Effects of low-dose, controlled-release, phentermine plus topiramate combination on weight and associated comorbidities in overweight and obese adults (CONQUER): a randomised, placebo-controlled, phase 3 trial.
Background: Obesity is associated with a reduction in life expectancy and an increase in mortality from cardiovascular diseases, cancer, and other causes. We therefore assessed the efficacy and safety of two doses of phentermine plus topiramate controlled-release combination as an adjunct to diet and lifestyle modification for weight loss and metabolic risk reduction in individuals who were overweight and obese, with two or more risk factors.
Methods: In this 56-week phase 3 trial, we randomly assigned overweight or obese adults (aged 18-70 years), with a body-mass index of 27-45 kg/m(2) and two or more comorbidities (hypertension, dyslipidaemia, diabetes or prediabetes, or abdominal obesity) to placebo, once-daily phentermine 7·5 mg plus topiramate 46·0 mg, or once-daily phentermine 15·0 mg plus topiramate 92·0 mg in a 2:1:2 ratio in 93 centres in the USA. Drugs were administered orally. Patients were randomly assigned by use of a computer-generated algorithm that was implemented through an interactive voice response system, and were stratified by sex and diabetic status. Investigators, patients, and study sponsors were masked to treatment. Primary endpoints were the percentage change in bodyweight and the proportion of patients achieving at least 5% weight loss. Analysis was by intention to treat. This study is registered with Clinical Trials.gov, number NCT00553787.
Findings: Of 2487 patients, 994 were assigned to placebo, 498 to phentermine 7·5 mg plus topiramate 46·0 mg, and 995 to phentermine 15·0 mg plus topiramate 92·0 mg; 979, 488, and 981 patients, respectively, were analysed. At 56 weeks, change in bodyweight was -1·4 kg (least-squares mean -1·2%, 95% CI -1·8 to -0·7), -8·1 kg (-7·8%, -8·5 to -7·1; p<0·0001), and -10·2 kg (-9·8%, -10·4 to -9·3; p<0·0001) in the patients assigned to placebo, phentermine 7·5 mg plus topiramate 46·0 mg, and phentermine 15·0 mg plus topiramate 92·0 mg, respectively. 204 (21%) patients achieved at least 5% weight loss with placebo, 303 (62%; odds ratio 6·3, 95% CI 4·9 to 8·0; p<0·0001) with phentermine 7·5 mg plus topiramate 46·0 mg, and 687 (70%; 9·0, 7·3 to 11·1; p<0·0001) with phentermine 15·0 mg plus topiramate 92·0 mg; for ≥10% weight loss, the corresponding numbers were 72 (7%), 182 (37%; 7·6, 5·6 to 10·2; p<0·0001), and 467 (48%; 11·7, 8·9 to 15·4; p<0·0001). The most common adverse events were dry mouth (24 [2%], 67 [13%], and 207 [21%] in the groups assigned to placebo, phentermine 7·5 mg plus topiramate 46·0 mg, and phentermine 15·0 mg plus topiramate 92·0 mg, respectively), paraesthesia (20 [2%], 68 [14%], and 204 [21%], respectively), constipation (59 [6%], 75 [15%], and 173 [17%], respectively), insomnia (47 [5%], 29 [6%], and 102 [10%], respectively), dizziness (31 [3%], 36 [7%], 99 [10%], respectively), and dysgeusia (11 [1%], 37 [7%], and 103 [10%], respectively). 38 (4%) patients assigned to placebo, 19 (4%) to phentermine 7·5 mg plus topiramate 46·0 mg, and 73 (7%) to phentermine 15·0 mg plus topiramate 92·0 mg had depression-related adverse events; and 28 (3%), 24 (5%), and 77 (8%), respectively, had anxiety-related adverse events.
Interpretation: The combination of phentermine and topiramate, with office-based lifestyle interventions, might be a valuable treatment for obesity that can be provided by family doctors.

Psychiatry · randomised controlled trial Comparison of behavioural activation with guided self-help for treatment of depression in adults with intellectual disabilities: a randomised controlled trial.
Background: Psychological therapies are first-line interventions for depression, but existing provision is not accessible for many adults with intellectual disabilities. We investigated the clinical and cost-effectiveness of a behavioural activation intervention (BeatIt) for people with intellectual disabilities and depression. BeatIt was compared with a guided self-help intervention (StepUp).
Methods: We did a multicentre, single-blind, randomised, controlled trial with follow-up at 4 months and 12 months after randomisation. Participants aged 18 years or older, with mild to moderate intellectual disabilities and clinically significant depression were recruited from health and social care services in the UK. The primary outcome was the Glasgow Depression Scale for people with a Learning Disability (GDS-LD) score at 12 months. Analyses were done on an intention-to-treat basis. This trial is registered with ISCRTN, number ISRCTN09753005.
Findings: Between Aug 8, 2013, and Sept 1, 2015, 161 participants were randomly assigned (84 to BeatIt; 77 to StepUp); 141 (88%) participants completed the trial. No group differences were found in the effects of BeatIt and StepUp based on GDS-LD scores at 12 months (12·03 [SD 7·99] GDS-LD points for BeatIt vs 12·43 [SD 7·64] GDS-LD points for StepUp; mean difference 0·26 GDS-LD points [95% CI -2·18 to 2·70]; p=0·833). Within-group improvements in GDS-LD scores occurred in both groups at 12 months (BeatIt, mean change -4·2 GDS-LD points [95% CI -6·0 to -2·4], p<0·0001; StepUp, mean change -4·5 GDS-LD points [-6·2 to -2·7], p<0·0001), with large effect sizes (BeatIt, 0·590 [95% CI 0·337-0·844]; StepUp, 0·627 [0·380-0·873]). BeatIt was not cost-effective when compared with StepUp, although the economic analyses indicated substantial uncertainty. Treatment costs were only approximately 3·6-6·8% of participants' total support costs. No treatment-related or trial-related adverse events were reported.
Interpretation: This study is, to our knowledge, the first large randomised controlled trial assessing individual psychological interventions for people with intellectual disabilities and mental health problems. These findings show that there is no evidence that BeatIt is more effective than StepUp; both are active and potentially effective interventions.

(2012)MEDLINE-indexed journal, not yet read by usLancet (London, England) Cancer mortality in India: a nationally representative survey.
Background: The age-specific mortality rates and total deaths from specific cancers have not been documented for the various regions and subpopulations of India. We therefore assessed the cause of death in 2001-03 in homes in small areas that were chosen to be representative of all the parts of India.
Methods: At least 130 trained physicians independently assigned causes to 122,429 deaths, which occurred in 1·1 million homes in 6671 small areas that were randomly selected to be representative of all of India, based on a structured non-medical surveyor's field report.
Findings: 7137 of 122,429 study deaths were due to cancer, corresponding to 556,400 national cancer deaths in India in 2010. 395,400 (71%) cancer deaths occurred in people aged 30-69 years (200,100 men and 195,300 women). At 30-69 years, the three most common fatal cancers were oral (including lip and pharynx, 45,800 [22·9%]), stomach (25,200 [12·6%]), and lung (including trachea and larynx, 22,900 [11·4%]) in men, and cervical (33,400 [17·1%]), stomach (27,500 [14·1%]), and breast (19,900 [10·2%]) in women. Tobacco-related cancers represented 42·0% (84,000) of male and 18·3% (35,700) of female cancer deaths and there were twice as many deaths from oral cancers as lung cancers. Age-standardised cancer mortality rates per 100,000 were similar in rural (men 95·6 [99% CI 89·6-101·7] and women 96·6 [90·7-102·6]) and urban areas (men 102·4 [92·7-112·1] and women 91·2 [81·9-100·5]), but varied greatly between the states, and were two times higher in the least educated than in the most educated adults (men, illiterate 106·6 [97·4-115·7] vs most educated 45·7 [37·8-53·6]; women, illiterate 106·7 [99·9-113·6] vs most educated 43·4 [30·7-56·1]). Cervical cancer was far less common in Muslim than in Hindu women (study deaths 24, age-standardised mortality ratio 0·68 [0·64-0·71] vs 340, 1·06 [1·05-1·08]).
Interpretation: Prevention of tobacco-related and cervical cancers and earlier detection of treatable cancers would reduce cancer deaths in India, particularly in the rural areas that are underserved by cancer services. The substantial variation in cancer rates in India suggests other risk factors or causative agents that remain to be discovered.

Symptoms and Distress in Children With Advanced Cancer: Prospective Patient-Reported Outcomes From the PediQUEST Study.
Purpose: Thousands of children are living with advanced cancer; yet patient-reported outcomes (PROs) have rarely been used to describe their experiences. We aimed to describe symptom distress in 104 children age 2 years or older with advanced cancer enrolled onto the Pediatric Quality of Life and Evaluation of Symptoms Technology (PediQUEST) Study (multisite clinical trial evaluating an electronic PRO system).
Methods: Symptom data were collected using age- and respondent-adapted versions of the PediQUEST Memorial Symptom Assessment Scale (PQ-MSAS) at most once per week. Clinical and treatment data were obtained from medical records. Individual symptom scores were dichotomized into high/low distress. Determinants of PQ-MSAS scores were explored using linear mixed-effects models.
Results: During 9 months of follow-up, PQ-MSAS was administered 920 times: 459 times in teens (99% self-report), 249 times in children ages 7 to 12 years (96% child/parent report), and 212 times in those ages 2 to 6 years (parent reports). Common symptoms included pain (48%), fatigue (46%), drowsiness (39%), and irritability (37%); most scores indicated high distress. Among the 73 PQ-MSAS surveys administered in the last 12 weeks of life, pain was highly prevalent (62%; 58% with high distress). Being female, having a brain tumor, experiencing recent disease progression, and receiving moderate- or high-intensity cancer-directed therapy in the prior 10 days were associated with worse PQ-MSAS scores. In the final 12 weeks of life, receiving mild cancer-directed therapy was associated with improved psychological PQ-MSAS scores.
Conclusion: Children with advanced cancer experience high symptom distress. Strategies to promote intensive symptom management are indicated, especially with disease progression or administration of intensive treatments.

Psychological Resources and Strategies to Cope with Stress at Work.
Introduction: the choice of strategies to cope with stress has differential effects on individual and organizational outcomes (e.g. well-being and performance at work). This study examined to what extent individuals differing in their positive psychological resources (optimism, hope, self-efficacy and resilience) implement different strategies to cope with stress in terms of change, acceptance, or withdrawal from a source of stress in an organizational setting.
Method: A questionnaire was filled out by 554 employees from different organizations representing a wide range of jobs and positions.
Results: Structural Equation Modeling (SEM; χ 2(7) = 27.64, ρ < .01, GFI = .99, NFI = .91, CFI = .93, RMSEA = .07).
Conclusion: the results indicated that psychological resources (optimism, hope, self-efficacy and resilience) were positively related to coping by change and by acceptance and negatively related to withdrawal. The theoretical implications are discussed.

Virtual reality biofeedback interventions for treating anxiety : A systematic review, meta-analysis and future perspective.
Background: Virtual reality (VR)-based biofeedback is a relatively new intervention and is increasingly being used for the treatment of anxiety disorders. This is the first research synthesis regarding effects and efficacy of this novel mode of treatment.
Method: We conducted a systematic review and meta-analysis of the VR biofeedback literature on treating anxiety symptoms. The MEDLINE/PubMed, Scopus and Web of Science databases were searched for eligible pre-post comparisons and randomized controlled trials (RCTs). We used self-reported anxiety, heart rate (HR), and heart rate variability (HRV) as primary outcome measures.
Results: A total of 7 studies with 191 participants reported VR biofeedback interventions. Of these studies 5 were RCTs, with 103 participants receiving VR biofeedback and 99 control participants (either 2D biofeedback or waiting list controls). We found that VR biofeedback significantly lowers self-reported anxiety (g = -0.28) and HR (g = -0.45), but not HRV. Furthermore, there were no significant differences in outcomes between VR biofeedback and 2D biofeedback but a significant reduction in HR in the VR biofeedback group compared with the waiting list (g = -0.52).
Conclusion: While the first findings are optimistic, more controlled studies with a wider variety of samples are needed to bring this field forward. Particularly, children and adolescents may profit from the combination of gamification elements, VR, and biofeedback.

Behavioural and cognitive-behavioural interventions for outwardly directed aggressive behaviour in people with intellectual disabilities.
Background: Outwardly directed aggressive behaviour in people with intellectual disabilities is a significant issue that may lead to poor quality of life, social exclusion and inpatient psychiatric admissions. Cognitive and behavioural approaches have been developed to manage aggressive behaviour but the effectiveness of these interventions on reducing aggressive behaviour and other outcomes are unclear. This is the third update of this review and adds nine new studies, resulting in a total of 15 studies in this review.
Objectives: To evaluate the efficacy of behavioural and cognitive-behavioural interventions on outwardly directed aggressive behaviour compared to usual care, wait-list controls or no treatment in people with intellectual disability. We also evaluated enhanced interventions compared to non-enhanced interventions.
Search methods: We used standard, extensive Cochrane search methods. The latest search date was March 2022. We revised the search terms to include positive behaviour support (PBS).
Selection criteria: We included randomised and quasi-randomised trials of children and adults with intellectual disability of any duration, setting and any eligible comparator.
Data collection and analysis: We used standard Cochrane methods. Our primary outcomes were change in 1. aggressive behaviour, 2. ability to control anger, and 3. adaptive functioning, and 4.
Adverse effects: Our secondary outcomes were change in 5. mental state, 6. medication, 7. care needs and 8. quality of life, and 9. frequency of service utilisation and 10. user satisfaction data. We used GRADE to assess certainty of evidence for each outcome. We expressed treatment effects as mean differences (MD) or odds ratios (OR), with 95% confidence intervals (CI). Where possible, we pooled data using a fixed-effect model.
Main results: This updated version comprises nine new studies giving 15 included studies and 921 participants. The update also adds new interventions including parent training (two studies), mindfulness-based positive behaviour support (MBPBS) (two studies), reciprocal imitation training (RIT; one study) and dialectical behavioural therapy (DBT; one study). It also adds two new studies on PBS. Most studies were based in the community (14 studies), and one was in an inpatient forensic service. Eleven studies involved adults only. The remaining studies involved children (one study), children and adolescents (one study), adolescents (one study), and adolescents and adults (one study). One study included boys with fragile X syndrome. Six studies were conducted in the UK, seven in the USA, one in Canada and one in Germany. Only five studies described sources of funding. Four studies compared anger management based on cognitive behaviour therapy to a wait-list or no treatment control group (n = 263); two studies compared PBS with treatment as usual (TAU) (n = 308); two studies compared carer training on mindfulness and PBS with PBS only (n = 128); two studies involving parent training on behavioural approaches compared to wait-list control or TAU (n = 99); one study of mindfulness to a wait-list control (n = 34); one study of adapted dialectal behavioural therapy compared to wait-list control (n = 21); one study of RIT compared to an active control (n = 20) and one study of modified relaxation compared to an active control group (n = 12). There was moderate-certainty evidence that anger management may improve severity of aggressive behaviour post-treatment (MD -3.50, 95% CI -6.21 to -0.79; P = 0.01; 1 study, 158 participants); very low-certainty evidence that it might improve self-reported ability to control anger (MD -8.38, 95% CI -14.05 to -2.71; P = 0.004, I2 = 2%; 3 studies, 212 participants), adaptive functioning (MD -21.73, 95% CI -36.44 to -7.02; P = 0.004; 1 study, 28 participants) and psychiatric symptoms (MD -0.48, 95% CI -0.79 to -0.17; P = 0.002; 1 study, 28 participants) post-treatment; and very low-certainty evidence that it does not improve quality of life post-treatment (MD -5.60, 95% CI -18.11 to 6.91; P = 0.38; 1 study, 129 participants) or reduce service utilisation and costs at 10 months (MD 102.99 British pounds, 95% CI -117.16 to 323.14; P = 0.36; 1 study, 133 participants). There was moderate-certainty evidence that PBS may reduce aggressive behaviour post-treatment (MD -7.78, 95% CI -15.23 to -0.32; P = 0.04, I2 = 0%; 2 studies, 275 participants) and low-certainty evidence that it probably does not reduce aggressive behaviour at 12 months (MD -5.20, 95% CI -13.27 to 2.87; P = 0.21; 1 study, 225 participants). There was low-certainty evidence that PBS does not improve mental state post-treatment (OR 1.44, 95% CI 0.83 to 2.49; P = 1.21; 1 study, 214 participants) and very low-certainty evidence that it might not reduce service utilisation at 12 months (MD -448.00 British pounds, 95% CI -1660.83 to 764.83; P = 0.47; 1 study, 225 participants). There was very low-certainty evidence that mindfulness may reduce incidents of physical aggression (MD -2.80, 95% CI -4.37 to -1.23; P < 0.001; 1 study; 34 participants) and low-certainty evidence that MBPBS may reduce incidents of aggression post-treatment (MD -10.27, 95% CI -14.86 to -5.67; P < 0.001, I2 = 87%; 2 studies, 128 participants). Reasons for downgrading the certainty of evidence were risk of bias (particularly selection and performance bias); imprecision (results from single, often small studies, wide CIs, and CIs crossing the null effect); and inconsistency (statistical heterogeneity).
Authors' conclusions: There is moderate-certainty evidence that cognitive-behavioural approaches such as anger management and PBS may reduce outwardly directed aggressive behaviour in the short term but there is less certainty about the evidence in the medium and long term, particularly in relation to other outcomes such as quality of life. There is some evidence to suggest that combining more than one intervention may have cumulative benefits. Most studies were small and there is a need for larger, robust randomised controlled trials, particularly for interventions where the certainty of evidence is very low. More trials are needed that focus on children and whether psychological interventions lead to reductions in the use of psychotropic medications.

(2016)MEDLINE-indexed journal, not yet read by usLancet (London, England) · randomised controlled trial Cost and Outcome of Behavioural Activation versus Cognitive Behavioural Therapy for Depression (COBRA): a randomised, controlled, non-inferiority trial.
Background: Depression is a common, debilitating, and costly disorder. Many patients request psychological therapy, but the best-evidenced therapy-cognitive behavioural therapy (CBT)-is complex and costly. A simpler therapy-behavioural activation (BA)-might be as effective and cheaper than is CBT. We aimed to establish the clinical efficacy and cost-effectiveness of BA compared with CBT for adults with depression.
Methods: In this randomised, controlled, non-inferiority trial, we recruited adults aged 18 years or older meeting Diagnostic and Statistical Manual of Mental Disorders IV criteria for major depressive disorder from primary care and psychological therapy services in Devon, Durham, and Leeds (UK). We excluded people who were receiving psychological therapy, were alcohol or drug dependent, were acutely suicidal or had attempted suicide in the previous 2 months, or were cognitively impaired, or who had bipolar disorder or psychosis or psychotic symptoms. We randomly assigned participants (1:1) remotely using computer-generated allocation (minimisation used; stratified by depression severity [Patient Health Questionnaire 9 (PHQ-9) score of <19 vs ≥19], antidepressant use, and recruitment site) to BA from junior mental health workers or CBT from psychological therapists. Randomisation done at the Peninsula Clinical Trials Unit was concealed from investigators. Treatment was given open label, but outcome assessors were masked. The primary outcome was depression symptoms according to the PHQ-9 at 12 months. We analysed all those who were randomly allocated and had complete data (modified intention to treat [mITT]) and also all those who were randomly allocated, had complete data, and received at least eight treatment sessions (per protocol [PP]). We analysed safety in the mITT population. The non-inferiority margin was 1·9 PHQ-9 points. This trial is registered with the ISCRTN registry, number ISRCTN27473954.
Findings: Between Sept 26, 2012, and April 3, 2014, we randomly allocated 221 (50%) participants to BA and 219 (50%) to CBT. 175 (79%) participants were assessable for the primary outcome in the mITT population in the BA group compared with 189 (86%) in the CBT group, whereas 135 (61%) were assessable in the PP population in the BA group compared with 151 (69%) in the CBT group. BA was non-inferior to CBT (mITT: CBT 8·4 PHQ-9 points [SD 7·5], BA 8·4 PHQ-9 points [7·0], mean difference 0·1 PHQ-9 points [95% CI -1·3 to 1·5], p=0·89; PP: CBT 7·9 PHQ-9 points [7·3]; BA 7·8 [6·5], mean difference 0·0 PHQ-9 points [-1·5 to 1·6], p=0·99). Two (1%) non-trial-related deaths (one [1%] multidrug toxicity in the BA group and one [1%] cancer in the CBT group) and 15 depression-related, but not treatment-related, serious adverse events (three in the BA group and 12 in the CBT group) occurred in three [2%] participants in the BA group (two [1%] patients who overdosed and one [1%] who self-harmed) and eight (4%) participants in the CBT group (seven [4%] who overdosed and one [1%] who self-harmed).
Interpretation: We found that BA, a simpler psychological treatment than CBT, can be delivered by junior mental health workers with less intensive and costly training, with no lesser effect than CBT. Effective psychological therapy for depression can be delivered without the need for costly and highly trained professionals.

(2018)MEDLINE-indexed journal, not yet read by usChild abuse & neglect · randomised controlled trial The impact of SafeCare® Dads to Kids program on father maltreatment risk and involvement: Outcomes and lessons learned from an efficacy trial.
Child Maltreatment (CM) is a public health problem, and experts recommend parent training programs as a prevention method. Few programs target fathers, even though male caregivers are involved as perpetrators in approximately 45% of substantiated CM cases. This study examines the efficacy of an adapted version of SafeCare (Dad2K) with marginalized fathers. Participants include a convenience sample of fathers with children ages 2-5 years. Fathers (n=99) were randomized to an 1) intervention group (SafeCare Dad2K) or to a 2) comparison group (receiving parenting information in the mail). Quantitative data were collected at baseline, post-intervention (7-weeks post-baseline), and 3-months post-intervention. Qualitative data (semi-structured interviews) were collected from 11 intervention father completers following the second quantitative data collection timepoint. Multi-level modeling results indicated no statistically significant time-by-treatment findings for father involvement (b=0.03, 95% confidence interval [CI]: -0.03, 0.08, p=0.38), total corporal punishment (b=-0.03, 95% CI: -0.47, 0.41, p=0.89), or neglect (b=-0.13, 95% CI: -1.93, 1.68, p=0.89). Qualitative findings indicated that Dad2K completers exhibited positive knowledge and behavioral change related to parenting. Study limitations, lessons learned from this formative work, and recommendations for future research are discussed.

(2015)MEDLINE-indexed journal, not yet read by usThe Lancet. Infectious diseases · randomised controlled trial Inactivated poliovirus vaccine given alone or in a sequential schedule with bivalent oral poliovirus vaccine in Chilean infants: a randomised, controlled, open-label, phase 4, non-inferiority study.
Background: Bivalent oral poliovirus vaccine (bOPV; types 1 and 3) is expected to replace trivalent OPV (tOPV) globally by April, 2016, preceded by the introduction of at least one dose of inactivated poliovirus vaccine (IPV) in routine immunisation programmes to eliminate vaccine-associated or vaccine-derived poliomyelitis from serotype 2 poliovirus. Because data are needed on sequential IPV-bOPV schedules, we assessed the immunogenicity of two different IPV-bOPV schedules compared with an all-IPV schedule in infants.
Methods: We did a randomised, controlled, open-label, non-inferiority trial with healthy, full-term (>2·5 kg birthweight) infants aged 8 weeks (± 7 days) at six well-child clinics in Santiago, Chile. We used supplied lists to randomly assign infants (1:1:1) to receive three polio vaccinations (IPV by injection or bOPV as oral drops) at age 8, 16, and 24 weeks in one of three sequential schedules: IPV-bOPV-bOPV, IPV-IPV-bOPV, or IPV-IPV-IPV. We did the randomisation with blocks of 12 stratified by study site. All analyses were done in a masked manner. Co-primary outcomes were non-inferiority of the bOPV-containing schedules compared with the all-IPV schedule for seroconversion (within a 10% margin) and antibody titres (within two-thirds log2 titres) to poliovirus serotypes 1 and 3 at age 28 weeks, analysed in the per-protocol population. Secondary outcomes were seroconversion and titres to serotype 2 and faecal shedding for 4 weeks after a monovalent OPV type 2 challenge at age 28 weeks. Safety analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01841671, and is closed to new participants.
Findings: Between April 25 and August 1, 2013, we assigned 570 infants to treatment: 190 to IPV-bOPV-bOPV, 192 to IPV-IPV-bOPV, and 188 to IPV-IPV-IPV. 564 (99%) were vaccinated and included in the intention-to-treat cohort, and 537 (94%) in the per-protocol analyses. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroconversion to type 1 poliovirus were 166 (98·8%) of 168, 95% CI 95·8-99·7; 178 (100%), 97·9-100·0; and 175 (100%), 97·9-100·0. Proportions with seroconvsion to type 3 poliovirus were 163 (98·2%) of 166, 94·8-99·4; 177 (100%), 97·9-100·0, and 172 (98·9%) of 174, 95·9-99·7. Non-inferiority was thus shown for the bOPV-containing schedules compared with the all-IPV schedule, with no significant differences between groups. In the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, the proportions of children with seroprotective antibody titres to type 1 poliovirus were 168 (98·8%) of 170, 95% CI 95·8-99·7; 181 (100%), 97·9-100·0; and 177 (100%), 97·9-100·0. Proportions to type 3 poliovirus were 166 (98·2%) of 169, 94·9-99·4; 180 (100%), 97·9-100·0; and 174 (98·9%) of 176, 96·0-99·7. Non-inferiority comparisons could not be done for this outcome because median titres for the groups receiving OPV were greater than the assay's upper limit of detection (log2 titres >10·5). The proportions of children seroconverting to type 2 poliovirus in the IPV-bOPV-bOPV, IPV-IPV-bOPV, and IPV-IPV-IPV groups, respectively, were 130 (77·4%) of 168, 95% CI 70·5-83·0; 169 (96·0%) of 176, 92·0-98·0; and 175 (100%), 97·8-100. IPV-bOPV schedules resulted in almost a 0·3 log reduction of type 2 faecal shedding compared with the IPV-only schedule. No participants died during the trial; 81 serious adverse events were reported, of which one was thought to be possibly vaccine-related (intestinal intussusception).
Interpretation: Seroconversion rates against polioviruses types 1 and 3 were non-inferior in sequential schedules containing IPV and bOPV, compared with an all-IPV schedule, and proportions of infants with protective antibodies were high after all three schedules. One or two doses of bOPV after IPV boosted intestinal immunity for poliovirus type 2, suggesting possible cross protection. Additionally, there was evidence of humoral priming for type 2 from one dose of IPV. Our findings could give policy makers flexibility when choosing a vaccination schedule, especially when trying to eliminate vaccine-associated and vaccine-derived poliomyelitis.

Shinde S, Weiss HA, Varghese B, Khandeparkar P, Pereira B, Sharma A, Gupta R, Ross DA, Patton G, Patel V. (2018)MEDLINE-indexed journal, not yet read by usLancet (London, England) · randomised controlled trial Promoting school climate and health outcomes with the SEHER multi-component secondary school intervention in Bihar, India: a cluster-randomised controlled trial.
Background: School environments affect health and academic outcomes. With increasing secondary school retention in low-income and middle-income countries, promoting quality school social environments could offer a scalable opportunity to improve adolescent health and wellbeing.
Methods: We did a cluster-randomised trial to assess the effectiveness of a multi-component whole-school health promotion intervention (SEHER) with integrated economic and process evaluations in grade 9 students (aged 13-14 years) at government-run secondary schools in the Nalanda district of Bihar state, India. Schools were randomly assigned (1:1:1) to three groups: the SEHER intervention delivered by a lay counsellor (the SEHER Mitra [SM] group), the SEHER intervention delivered by a teacher (teacher as SEHER Mitra [TSM] group), and a control group in which only the standard government-run classroom-based life-skills Adolescence Education Program was implemented. The primary outcome was school climate measured with the Beyond Blue School Climate Questionnaire (BBSCQ). Students were assessed at the start of the academic year (June, 2015) and again 8 months later at the end of the academic year (March, 2016) via self-completed questionnaires. This study is registered with ClinicalTrials.gov, number NCT02484014.
Findings: Of the 112 eligible schools in the Nalanda district, 75 were randomly selected to participate in the trial. We randomly assigned 25 schools to each of the three groups. One school subsequently dropped out of the TSM group, leaving 24 schools in this group. The baseline survey included a total of 13 035 participants, and the endpoint survey included 14 414 participants. Participants in the SM-delivered intervention schools had substantially higher school climate scores at endpoint survey than those in the control group (BBSCQ baseline-adjusted mean difference [aMD] 7·57 [95% CI 6·11-9·03]; effect size 1·88 [95% CI 1·44-2·32], p<0·0001) and the TSM-delivered intervention (aMD 7·57 [95% CI 6·06-9·08]; effect size 1·88 [95% CI 1·43-2·34], p<0·0001). There was no effect of the TSM-delivered intervention compared with control (aMD -0·009 [95% CI -1·53 to 1·51], effect size 0·00 [95% CI -0·45 to 0·44], p=0·99). Compared with the control group, participants in the SM-delivered intervention schools had moderate to large improvements in the secondary outcomes of depression (aMD -1·23 [95% CI -1·89 to -0·57]), bullying (aMD -0·91 [95% CI -1·15 to -0·66]), violence victimisation (odds ratio [OR] 0·62 [95% CI 0·46-0·84]), violence perpetration (OR 0·68 [95% CI 0·48-0·96]), attitude towards gender equity (aMD 0·41 [95% CI 0·21-0·61]), and knowledge of reproductive and sexual health (aMD 0·29 [95% CI 0·06-0·53]). Similar results for these secondary outcomes were noted for the comparison between SM-delivered intervention schools and TSM-delivered intervention schools (depression: aMD -1·23 [95% CI -1·91 to -0·55]; bullying: aMD -0·83 [95% CI -1·08 to -0·57]; violence victimisation: OR 0·49 [95% CI 0·35-0·67]; violence perpetration: OR 0·49 [95% CI 0·34-0·71]; attitude towards gender equity: aMD 0·23 [95% CI 0·02-0·44]; and knowledge of reproductive and sexual health: aMD 0·22 [95% CI -0·02 to 0·47]). However, no effects on these secondary outcomes were observed for the TSM-delivered intervention schools compared with the control group (depression: aMD -0·03 [95% CI -0·70 to 0·65]; bullying: aMD -0·08 [95% CI -0·34 to 0·18]; violence victimisation: OR 1·27 [95% CI 0·93-1·73]; violence perpetration: OR 1·37 [95% CI 0·95-1·95]; attitude towards gender equity: aMD 0·17 [95% CI -0·09 to 0·38]; and knowledge of reproductive and sexual health: aMD 0·06 [95% CI -0·18 to 0·32]).
Interpretation: The multi-component whole-school SEHER health promotion intervention had substantial beneficial effects on school climate and health-related outcomes when delivered by lay counsellors, but no effects when delivered by teachers. Future research should focus on the evaluation of the scaling up of the SEHER intervention in diverse contexts and delivery agents.

(2021)MEDLINE-indexed journal, not yet read by usThe lancet. Diabetes & endocrinology · randomised controlled trial A community-based, multi-level, multi-setting, multi-component intervention to reduce weight gain among low socioeconomic status Latinx children with overweight or obesity: The Stanford GOALS randomised controlled trial.
Background: There are few long-term studies of interventions to reduce in low socioeconomic status children with overweight or obesity. The Stanford GOALS trial evaluated a 3-year, community-based, multi-level, multi-setting, multi-component (MMM) systems intervention, to reduce weight gain among low socioeconomic status, Latinx children with overweight or obesity.
Methods: We did a two-arm, parallel group, randomised, open-label, active placebo-controlled trial with masked assessment over 3 years. Families from low-income, primarily Latinx communities in Northern California, CA, USA, with 7-11-year-old children with overweight or obesity were randomly assigned to a MMM intervention or a Health Education (HE) comparison intervention. The MMM intervention included home environment changes and behavioural counselling, community after school team sports, and reports to primary health-care providers. The primary outcome was child BMI trajectory over three years. Secondary outcomes included one- and two-year changes in BMI. This trial is registered with ClinicalTrials.govNCT01642836.
Findings: Between July 13, 2012, and Oct 3, 2013, 241 families were recruited and randomly assigned to MMM (n=120) or HE (n=121). Children's mean age was 9·5 (SD 1·4) years, 134 (56%) were female and 107 (44%) were male, and 236 (98%) were Latinx. 238 (99%) children participated in year 1, 233 (97%) in year 2, and 227 (94%) in year 3 of follow-up assessments. In intention-to-treat analysis, over 3 years, the difference between intervention groups in BMI trajectory was not significant (mean adjusted difference -0·25 [95% CI -0·90 to 0·40] kg/m2; Cohen's d=0.10; p=0·45). Children in the MMM intervention group gained less BMI over 1 year than did children in the HE intervention group (-0·73 [-1·07 to -0·39] kg/m2, d=0.55); the same was true over 2 years (-0·63 [-1·13 to -0·14] kg/m2; d =0.33). No differential adverse events were observed.
Interpretation: The MMM intervention did not reduce BMI gain versus HE over 3 years but the effects over 1 and 2 years in this rigorous trial show the promise of this systems intervention approach for reducing weight gain and cardiometabolic risk factors in low socioeconomic status communities.

Vitamin E in the primary prevention of cardiovascular disease and cancer: the Women's Health Study: a randomized controlled trial.
Context: Basic research provides plausible mechanisms and observational studies suggest that apparently healthy persons, who self-select for high intakes of vitamin E through diet or supplements, have decreased risks of cardiovascular disease and cancer. Randomized trials do not generally support benefits of vitamin E, but there are few trials of long duration among initially healthy persons.
Objective: To test whether vitamin E supplementation decreases risks of cardiovascular disease and cancer among healthy women.
Design, setting, and participants: In the Women's Health Study conducted between 1992 and 2004, 39 876 apparently healthy US women aged at least 45 years were randomly assigned to receive vitamin E or placebo and aspirin or placebo, using a 2 x 2 factorial design, and were followed up for an average of 10.1 years.
Intervention: Administration of 600 IU of natural-source vitamin E on alternate days.
Main outcome measures: Primary outcomes were a composite end point of first major cardiovascular event (nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death) and total invasive cancer.
Results: During follow-up, there were 482 major cardiovascular events in the vitamin E group and 517 in the placebo group, a nonsignificant 7% risk reduction (relative risk [RR], 0.93; 95% confidence interval [CI], 0.82-1.05; P = .26). There were no significant effects on the incidences of myocardial infarction (RR, 1.01; 95% CI, 0.82-1.23; P = .96) or stroke (RR, 0.98; 95% CI, 0.82-1.17; P = .82), as well as ischemic or hemorrhagic stroke. For cardiovascular death, there was a significant 24% reduction (RR, 0.76; 95% CI, 0.59-0.98; P = .03). There was no significant effect on the incidences of total cancer (1437 cases in the vitamin E group and 1428 in the placebo group; RR, 1.01; 95% CI, 0.94-1.08; P = .87) or breast (RR, 1.00; 95% CI, 0.90-1.12; P = .95), lung (RR, 1.09; 95% CI, 0.83-1.44; P = .52), or colon cancers (RR, 1.00; 95% CI, 0.77-1.31; P = .99). Cancer deaths also did not differ significantly between groups. There was no significant effect of vitamin E on total mortality (636 in the vitamin E group and 615 in the placebo group; RR, 1.04; 95% CI, 0.93-1.16; P = .53).
Conclusions: The data from this large trial indicated that 600 IU of natural-source vitamin E taken every other day provided no overall benefit for major cardiovascular events or cancer, did not affect total mortality, and decreased cardiovascular mortality in healthy women. These data do not support recommending vitamin E supplementation for cardiovascular disease or cancer prevention among healthy women.

Internet-based intervention for smoking cessation (StopAdvisor) in people with low and high socioeconomic status: a randomised controlled trial.
Background: Internet-based interventions for smoking cessation could help millions of people stop smoking at very low unit costs; however, long-term biochemically verified evidence is scarce and such interventions might be less effective for smokers with low socioeconomic status than for those with high status because of lower online literacy to engage with websites. We aimed to assess a new interactive internet-based intervention (StopAdvisor) for smoking cessation that was designed with particular attention directed to people with low socioeconomic status.
Methods: We did this online randomised controlled trial between Dec 6, 2011, and Oct 11, 2013, in the UK. Participants aged 18 years and older who smoked every day were randomly assigned (1:1) to receive treatment with StopAdvisor or an information-only website. Randomisation was automated with an unseen random number function embedded in the website to establish which treatment was revealed after the online baseline assessment. Recruitment continued until the required sample size had been achieved from both high and low socioeconomic status subpopulations. Participants, and researchers who obtained data and did laboratory analyses, were masked to treatment allocation. The primary outcome was 6 month sustained, biochemically verified abstinence. The main secondary outcome was 6 month, 7 day biochemically verified point prevalence. Analysis was by intention to treat. Homogeneity of intervention effect across the socioeconomic subsamples was first assessed to establish whether overall or separate subsample analyses were appropriate. The study is registered as an International Standard Randomised Controlled Trial, number ISRCTN99820519.
Findings: We randomly assigned 4613 participants to the StopAdvisor group (n=2321) or the control group (n=2292); 2142 participants were of low socioeconomic status and 2471 participants were of high status. The overall rate of smoking cessation was similar between participants in the StopAdvisor and control groups for the primary (237 [10%] vs 220 [10%] participants; relative risk [RR] 1·06, 95% CI 0·89-1·27; p=0·49) and the secondary (358 [15%] vs 332 [15%] participants; 1·06, 0·93-1·22; p=0·37) outcomes; however, the intervention effect differed across socioeconomic status subsamples (1·44, 0·99-2·09; p=0·0562 and 1·37, 1·02-1·84; p=0·0360, respectively). StopAdvisor helped participants with low socioeconomic status stop smoking compared with the information-only website (primary outcome: 90 [8%] of 1088 vs 64 [6%] of 1054 participants; RR 1·36, 95% CI 1·00-1·86; p=0·0499; secondary outcome: 136 [13%] vs 100 [10%] participants; 1·32, 1·03-1·68, p=0·0267), but did not improve cessation rates in those with high socioeconomic status (147 [12%] of 1233 vs 156 [13%] of 1238 participants; 0·95, 0·77-1·17; p=0·61 and 222 [18%] vs 232 [19%] participants; 0·96, 0·81-1·13, p=0·64, respectively).
Interpretation: StopAdvisor was more effective than an information-only website in smokers of low, but not high, socioeconomic status. StopAdvisor could be implemented easily and made freely available, which would probably improve the success rates of smokers with low socioeconomic status who are seeking online support.

Validation of the IDF-DAR risk tool for fasting in Ramadan for adults with diabetes mellitus in primary care: A nationwide multicentre study in Malaysia.
Introduction: Fasting during Ramadan is a religious obligation for Muslims but poses health risks for individuals with diabetes mellitus. The International Diabetes Federation-Diabetes and Ramadan Alliance (IDF-DAR) introduced a risk stratification tool in 2021 to guide clinicians, though its utility in primary care settings remains limited.
Methods: A retrospective observational study was conducted on adults with diabetes attending government health clinics in Malaysia from April 15 to June 15, 2024. Medical records of those who attempted fasting during Ramadan were reviewed. The primary outcome was a composite of hypoglycaemia, hyperglycaemia, diabetes-related hospitalization, or dehydration leading to breaking the fast. Discriminative performance of the IDF-DAR tool was evaluated using area under the receiver operating characteristic curve (AUC). Calibration was assessed via the Hosmer-Lemeshow test.
Results: A total of 310 patients were included (99 % with type 2 diabetes). The mean age was 61 years and the median diabetes duration was 7 years. Adverse fasting outcomes were observed in 18.4 % of patients, with hypoglycaemia being the most common (13.5 %). The IDF-DAR risk stratification tool demonstrated good discriminative ability, achieving an area under the ROC curve (AUC) of 0.78 (95 % CI: 0.72-0.84). At the recommended cut-off for distinguishing low-moderate from high-risk categories, the tool achieved a sensitivity of 92.9 % and a specificity of 40.9 %. The Hosmer-Lemeshow goodness-of-fit test indicated poor agreement between observed and predicted adverse outcomes, with a statistically significant result (P < 0.05).
Conclusion: The IDF-DAR risk stratification tool identifies high-risk patients fasting during Ramadan in primary care. However, its poor calibration and specificity as highlights the need for refinement of the model to improve its predictive accuracy. Enhancing the tool's calibration could allow for better individual risk estimation and more precise clinical decision-making in diverse primary care settings.

Capitalizing on everyday positive events uniquely predicts daily intimacy and well-being in couples coping with breast cancer.
Capitalization is the relational process of savoring positive life events by sharing them with responsive relationship partners. The purpose of the present study was to use dyadic intensive longitudinal methods to examine novel hypotheses regarding links between capitalization processes and daily intimacy and well-being in women with breast cancer and their intimate partners. Although couples coping with cancer often experience an increase in negative daily life events, we hypothesized that it would be important for them to share and capitalize on positive events in addition to sharing negative events. Female patients with early stage breast cancer and their intimate partners (99 couples) completed electronic daily diaries for 7 to 10 consecutive days tapping everyday processes of sharing negative and positive events with each other. Dyadic multilevel process modeling revealed that on days when capitalization attempts (i.e., sharing the best event of the day) occurred, daily feelings of intimacy in the sharer were higher for both patients and partners. Moreover, greater perceived partner responsiveness to capitalization attempts was associated with increases in the sharer's daily feelings of intimacy and decreases in the sharer's daily negative affect. When the patient's partner was the sharer, perceived partner responsiveness also was associated with increased daily positive affect. More important, all effects of capitalization were observed above and beyond the effects of event positivity and sharing negative events (i.e., social support attempts). Findings suggest that, even in the midst of significant life adversity, sharing daily good news with intimate partners enhances relationship well-being independently of sharing bad news.

Background: Transcaval access may enable fully percutaneous transcatheter aortic valve replacement (TAVR) without the hazards and discomfort of transthoracic (transapical or transaortic) access.
Objectives: The authors performed a prospective, independently adjudicated, multicenter, single-arm trial of transcaval access for TAVR in patients who were ineligible for femoral artery access and had high or prohibitive risk of complications from transthoracic access.
Methods: A total of 100 patients underwent attempted percutaneous transcaval access to the abdominal aorta by electrifying a caval guidewire and advancing it into a pre-positioned aortic snare. After exchanging for a rigid guidewire, conventional TAVR was performed through transcaval introducer sheaths. Transcaval access ports were closed with nitinol cardiac occluders. A core laboratory analyzed pre-discharge and 30-day abdominal computed tomograms. The Society of Thoracic Surgeons predicted risk of mortality was 9.6 ± 6.3%.
Results: Transcaval access was successful in 99 of 100 patients. Device success (access and closure with a nitinol cardiac occluder without death or emergency surgical rescue) occurred 98 of 99 patients; 1 subject had closure with a covered stent. Inpatient survival was 96%, and 30-day survival was 92%. Second Valve Academic Research Consortium (VARC-2) life-threatening bleeding and modified VARC-2 major vascular complications possibly related to transcaval access were 7% and 13%, respectively. Median length of stay was 4 days (range 2 to 6 days). There were no vascular complications after discharge.
Conclusions: Transcaval access enabled TAVR in patients who were not good candidates for transthoracic access. Bleeding and vascular complications, using permeable nitinol cardiac occluders to close the access ports, were common but acceptable in this high-risk cohort. Transcaval access should be investigated in patients who are eligible for transthoracic access. Purpose-built closure devices are in development that may simplify the procedure and reduce bleeding.

Prevalence of and Factors Related to Discordance About Prognosis Between Physicians and Surrogate Decision Makers of Critically Ill Patients.
Importance: Misperceptions about prognosis by individuals making decisions for incapacitated critically ill patients (surrogates) are common and often attributed to poor comprehension of medical information.
Objective: To determine the prevalence of and factors related to physician-surrogate discordance about prognosis in intensive care units (ICUs).
Design, setting, and participants: Mixed-methods study comprising quantitative surveys and qualitative interviews conducted in 4 ICUs at a major US medical center involving surrogate decision makers and physicians caring for patients at high risk of death from January 4, 2005, to July 10, 2009.
Main outcomes and measures: Discordance about prognosis, defined as a difference between a physician's and a surrogate's prognostic estimates of at least 20%; misunderstandings by surrogates (defined as any difference between a physician's prognostic estimate and a surrogate's best guess of that estimate); differences in belief (any difference between a surrogate's actual estimate and their best guess of the physician's estimate).
Results: Two hundred twenty-nine surrogate decision makers (median age, 47 [interquartile range {IQR}, 35-56] years; 68% women) and 99 physicians were involved in the care of 174 critically ill patients (median age, 60 [IQR, 47-74] years; 44% women). Physician-surrogate discordance about prognosis occurred in 122 of 229 instances (53%; 95% CI, 46.8%-59.7%). In 65 instances (28%), discordance was related to both misunderstandings by surrogates and differences in belief about the patient's prognosis; 38 (17%) were related to misunderstandings by surrogates only; 7 (3%) were related to differences in belief only; and data were missing for 12. Seventy-five patients (43%) died. Surrogates' prognostic estimates were much more accurate than chance alone, but physicians' prognostic estimates were statistically significantly more accurate than surrogates' (C statistic, 0.83 vs 0.74; absolute difference, 0.094; 95% CI, 0.024-0.163; P = .008). Among 71 surrogates interviewed who had beliefs about the prognosis that were more optimistic than that of the physician, the most common reasons for optimism were a need to maintain hope to benefit the patient (n = 34), a belief that the patient had unique strengths unknown to the physician (n = 24), and religious belief (n = 19).
Conclusions and relevance: Among critically ill patients, discordant expectations about prognosis were common between patients' physicians and surrogate decision makers and were related to misunderstandings by surrogates about physicians' assessments of patients' prognoses and differences in beliefs about patients' prognoses.

(2014)MEDLINE-indexed journal, not yet read by usLancet (London, England) · cohort or longitudinal International standards for fetal growth based on serial ultrasound measurements: the Fetal Growth Longitudinal Study of the INTERGROWTH-21st Project.
Background: In 2006, WHO produced international growth standards for infants and children up to age 5 years on the basis of recommendations from a WHO expert committee. Using the same methods and conceptual approach, the Fetal Growth Longitudinal Study (FGLS), part of the INTERGROWTH-21(st) Project, aimed to develop international growth and size standards for fetuses.
Methods: The multicentre, population-based FGLS assessed fetal growth in geographically defined urban populations in eight countries, in which most of the health and nutritional needs of mothers were met and adequate antenatal care was provided. We used ultrasound to take fetal anthropometric measurements prospectively from 14 weeks and 0 days of gestation until birth in a cohort of women with adequate health and nutritional status who were at low risk of intrauterine growth restriction. All women had a reliable estimate of gestational age confirmed by ultrasound measurement of fetal crown-rump length in the first trimester. The five primary ultrasound measures of fetal growth--head circumference, biparietal diameter, occipitofrontal diameter, abdominal circumference, and femur length--were obtained every 5 weeks (within 1 week either side) from 14 weeks to 42 weeks of gestation. The best fitting curves for the five measures were selected using second-degree fractional polynomials and further modelled in a multilevel framework to account for the longitudinal design of the study.
Findings: We screened 13,108 women commencing antenatal care at less than 14 weeks and 0 days of gestation, of whom 4607 (35%) were eligible. 4321 (94%) eligible women had pregnancies without major complications and delivered live singletons without congenital malformations (the analysis population). We documented very low maternal and perinatal mortality and morbidity, confirming that the participants were at low risk of adverse outcomes. For each of the five fetal growth measures, the mean differences between the observed and smoothed centiles for the 3rd, 50th, and 97th centiles, respectively, were small: 2·25 mm (SD 3·0), 0·02 mm (3·0), and -2·69 mm (3·2) for head circumference; 0·83 mm (0·9), -0·05 mm (0·8), and -0·84 mm (1·0) for biparietal diameter; 0·63 mm (1·2), 0·04 mm (1·1), and -1·05 mm (1·3) for occipitofrontal diameter; 2·99 mm (3·1), 0·25 mm (3·2), and -4·22 mm (3·7) for abdominal circumference; and 0·62 mm (0·8), 0·03 mm (0·8), and -0·65 mm (0·8) for femur length. We calculated the 3rd, 5th 10th, 50th, 90th, 95th and 97th centile curves according to gestational age for these ultrasound measures, representing the international standards for fetal growth.
Interpretation: We recommend these international fetal growth standards for the clinical interpretation of routinely taken ultrasound measurements and for comparisons across populations.

Hospital treatment of patients with ischemic stroke or transient ischemic attack using the "Get With The Guidelines" program.
Background: Adherence to evidence-based interventions for hospitalized patients who have experienced a stroke is suboptimal. We examined the association of process improvement and Internet-based data collection and decision support with stroke care.
Methods: A 1-year intervention study to assess performance measure adherence in hospitals using the "Get With The Guidelines-Stroke" program. The program included 18 410 patients with ischemic stroke or transient ischemic attack admitted to 99 volunteer community and teaching hospitals. Data from eligible patients in the preintervention baseline period were compared with data from 4 subsequent quarters for 12 acute care or secondary prevention measures and an all-or-none measure of care based on 7 prespecified measures.
Results: Significant improvements from baseline to the fourth quarter were seen in 11 of 13 measures: use of thrombolytic medications for patients with ischemic stroke presenting within 2 hours of onset, 23.5% vs 40.8% (P < .001); early use of antithrombotic medications, 88.2% vs 95.2% (P < .001); antithrombotic medications prescribed at discharge, 91.0% vs 97.9% (P < .001); anticoagulation agents for atrial fibrillation, 81.4% vs 96.5% (P < .001); smoking cessation counseling, 38.3% vs 54.5% (P < .001); lipid treatment for low-density lipoprotein levels 100 mg/dL or greater, 58.7% vs 77.0% (P < .001); diabetes mellitus treatment, 48.5% vs 83.5% (P = .001); and weight reduction counseling 32.5% vs 43.4% (P < .001). The all-or-none measure increased from 50.2% to 58.0% (P < .001). Complications from thrombolytic medications and prophylaxis for deep venous thrombosis did not change.
Conclusion: Statistically and clinically significant improvement in 11 of 13 quality improvement measures for the treatment of patients hospitalized for cerebrovascular disease was seen in hospitals participating in the Get With The Guidelines program.

(2012)MEDLINE-indexed journal, not yet read by usPlant molecular biology · cohort or longitudinal High-throughput sequencing-based gene profiling on multi-staged fruit development of date palm (Phoenix dactylifera, L.).
Date palm provides both staple food and gardening for the Middle East and North African countries for thousands of years. Its fruits have diversified significantly, such as nutritional content, size, length, weight color, and ripping process. Dates palm represent an excellent model system for the study of fruit development and diversity of fruit-bearing palm species that produce the most versatile fruit types as compared to other plant families. Using Roche/454 GS FLX instrument, we acquired 7.6 million sequence tags from seven fruiting stages (F1-F7). Over 99% of the raw reads are assembled, and the numbers of isotigs (equivalent to transcription units or unigenes) range from 30,684 to 40,378 during different fruiting stages. We annotated isotigs using BLASTX and BLASTN, and mapped 74% of the isotigs to known functional sequences or genes. Based on gene ontology categorization and pathway analysis, we have identified 10 core cell division genes, 18 ripening related genes, and 7 starch metabolic enzymes, which are involved as nutrition storage and sugar/starch metabolisms. We noticed that many metabolic pathways vary significantly during fruit development, and carbohydrate metabolism (especially sugar synthesis) is particularly prominent during fruit ripening. Transcriptomics study on various fruiting stages of date palm shows complicated metabolic activities during fruit development, ripening, synthesis and accumulation of starch enzymes and other related sugars. Most Genes are highly expressed in early stages of development, while late developmental stages are critical for fruit ripening including most of the metabolism associated ones.

Digital Technologies for Health Promotion and Disease Prevention in Older People: Scoping Review.
Background: Digital technologies have the potential to contribute to health promotion and disease prevention in the aging world.
Objective: This study aims to identify digital technologies for health promotion and disease prevention that could be used independently by older people in nonclinical settings using a scoping review.
Methods: Through database (MEDLINE, PsycINFO, CINAHL, and SCOPUS; to March 3, 2022) and manual searches (to June 14, 2022), 90 primary studies and 8 systematic reviews were included in this scoping review. The eligibility was based on the PCC (Population, Concept, and Context) criteria: (1) people aged 50 years or older (population), (2) any digital (health) technology (eg, smartphone apps, websites, virtual reality; concept), and (3) health promotion and disease prevention in daily life in nonclinical and noninstitutional settings (context). Data items included study characteristics, PCC criteria, opportunities versus challenges, and evidence gaps. Data were synthesized using descriptive statistics or narratively described by identifying common themes.
Results: The studies were published in 2005-2022 and originated predominantly from North America and Europe. Most primary studies were nonrandomized, reported quantitative data, and investigated effectiveness or feasibility (eg, acceptance or usability) of digital technologies in older people. The participants were aged 50 years to 99 years, predominantly female, affluent (ie, with high income, education, and digital competence), and intended to use or used digital technologies for a median of 3 months independently at home or in community settings. The digital technologies included mobile or nonmobile technologies or virtual reality. The studies used "modern devices" (eg, smartphones, wearables, or gaming consoles) or modern and "older devices" (eg, computers or mobile phones). The users interacted with digital technologies via websites, emails, text messages, apps, or virtual reality. Health targets of digital technologies were mobility, mental health, nutrition, or cognition. The opportunities versus challenges of digital technologies were (1) potential health benefits versus unclear or no benefits for some outcomes, (2) monitoring of health versus ethical issues with data collection and management, (3) implications for functioning in daily life (ie, potential to prolong independent living) versus unclear application for clinical management or care, (4) tailoring of technical properties and content toward older users versus general use, (5) importance of human support for feasibility versus other factors required to improve feasibility, (6) reduction of social isolation versus access to digital technologies, and (7) improvement in digital competence versus digital divide.
Conclusions: Various digital technologies were independently used by people aged 50 years or older for health promotion and disease prevention. Future studies should focus on (1) more diverse populations of older people, (2) new digital technologies, (3) other (clinical and care) settings, and (4) outcome evaluation to identify factors that could enhance any health benefits of digital technologies.

Lawn JE, Blencowe H, Oza S, You D, Lee AC, Waiswa P, Lalli M, Bhutta Z, Barros AJ, Christian P, Mathers C, Cousens SN, Lancet Every Newborn Study Group. (2014)MEDLINE-indexed journal, not yet read by usLancet (London, England) · review Every Newborn: progress, priorities, and potential beyond survival.
In this Series paper, we review trends since the 2005 Lancet Series on Neonatal Survival to inform acceleration of progress for newborn health post-2015. On the basis of multicountry analyses and multi-stakeholder consultations, we propose national targets for 2035 of no more than 10 stillbirths per 1000 total births, and no more than 10 neonatal deaths per 1000 livebirths, compatible with the under-5 mortality targets of no more than 20 per 1000 livebirths. We also give targets for 2030. Reduction of neonatal mortality has been slower than that for maternal and child (1-59 months) mortality, slowest in the highest burden countries, especially in Africa, and reduction is even slower for stillbirth rates. Birth is the time of highest risk, when more than 40% of maternal deaths (total about 290,000) and stillbirths or neonatal deaths (5·5 million) occur every year. These deaths happen rapidly, needing a rapid response by health-care workers. The 2·9 million annual neonatal deaths worldwide are attributable to three main causes: infections (0·6 million), intrapartum conditions (0·7 million), and preterm birth complications (1·0 million). Boys have a higher biological risk of neonatal death, but girls often have a higher social risk. Small size at birth--due to preterm birth or small-for-gestational-age (SGA), or both--is the biggest risk factor for more than 80% of neonatal deaths and increases risk of post-neonatal mortality, growth failure, and adult-onset non-communicable diseases. South Asia has the highest SGA rates and sub-Saharan Africa has the highest preterm birth rates. Babies who are term SGA low birthweight (10·4 million in these regions) are at risk of stunting and adult-onset metabolic conditions. 15 million preterm births, especially of those younger than 32 weeks' gestation, are at the highest risk of neonatal death, with ongoing post-neonatal mortality risk, and important risk of long-term neurodevelopmental impairment, stunting, and non-communicable conditions. 4 million neonates annually have other life-threatening or disabling conditions including intrapartum-related brain injury, severe bacterial infections, or pathological jaundice. Half of the world's newborn babies do not get a birth certificate, and most neonatal deaths and almost all stillbirths have no death certificate. To count deaths is crucial to change them. Failure to improve birth outcomes by 2035 will result in an estimated 116 million deaths, 99 million survivors with disability or lost development potential, and millions of adults at increased risk of non-communicable diseases after low birthweight. In the post-2015 era, improvements in child survival, development, and human capital depend on ensuring a healthy start for every newborn baby--the citizens and workforce of the future.

Originally published25 Jan 2000https://doi.org/10.1161/01.CIR.101.3.329Circulation. 2000;101:329–335Essential hypertension remains a major modifiable risk factor for cardiovascular disease (CVD) despite important advances in our understanding of its pathophysiology and the availability of effective treatment strategies. High blood pressure (BP) increases the risk of CVD for millions of people worldwide, and there is evidence that the problem is only getting worse. In the past decade, age-adjusted rates of stroke incidence have risen, and the slope of the age-adjusted rate of decline in coronary disease has leveled off. The incidence of end-stage renal disease and the prevalence of heart failure have also increased. A major contributor to these trends is inadequate control of BP in the hypertensive population. This review of current concepts regarding the definition, etiology, and treatment of essential hypertension is intended to aid the clinician in identifying those individuals at high risk who need to undergo evaluation and treatment, as well as in selecting optimal treatment strategies for hypertensive patients with comorbid conditions and/or target organ damage. The part of the review that deals with the genetic basis of hypertension and the gene/environment interaction that may lead to elevated BP is still a work in progress. Information gained from the Human Genome Project and from ongoing studies of the genetic basis of hypertension both in animal models and human populations may revolutionize the treatment of hypertension by replacing current empirical therapy with more effective, targeted treatments based on the genotype of the patient. Concepts introduced in this review form the basis for such "pharmacogenomic" approaches to antihypertensive therapy. Definition of Essential or Primary HypertensionBP is a quantitative trait that is highly variable1 ; in population studies, BP has a normal distribution that is slightly skewed to the right. There is a strong positive and continuous correlation between BP and the risk of CVD (stroke, myocardial infarction, heart failure), renal disease, and mortality, even in the normotensive range. This correlation is more robust with systolic than with diastolic BP.2 There is no specific level of BP where cardiovascular and renal complications start to occur; thus the definition of hypertension is arbitrary but needed for practical reasons in patient assessment and treatment. The Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VI) defined and classified hypertension in adults, as shown in Table 1.3 The diagnosis of hypertension is made when the average of 2 or more diastolic BP measurements on at least 2 subsequent visits is ≥90 mm Hg or when the average of multiple systolic BP readings on 2 or more subsequent visits is consistently ≥140 mm Hg. Isolated systolic hypertension is defined as systolic BP ≥140 mm Hg and diastolic BP <90 mm Hg. Individuals with high normal BP tend to maintain pressures that are above average for the general population and are at greater risk for development of definite hypertension and cardiovascular events than the general population. With the use of these definitions, it is estimated that 43 million people in the United States have hypertension or are taking antihypertensive medication, which is ≈24% of the adult population. This proportion changes with (1) race, being higher in blacks (32.4%) and lower in whites (23.3%) and Mexican Americans (22.6%); (2) age, because in industrialized countries systolic BP rises throughout life, whereas diastolic BP rises until age 55 to 60 years and thus the greater increase in prevalence of hypertension among the elderly is mainly due to systolic hypertension; (3) geographic patterns, because hypertension is more prevalent in the southeastern United States; (4) gender, because hypertension is more prevalent in men (though menopause tends to abolish this difference); and (5) socioeconomic status, which is an indicator of lifestyle attributes and is inversely related to the prevalence, morbidity, and mortality rates of hypertension. Essential, primary, or idiopathic hypertension is defined as high BP in which secondary causes such as renovascular disease, renal failure, pheochromocytoma, aldosteronism, or other causes of secondary hypertension or mendelian forms (monogenic) are not present. Essential hypertension accounts for 95% of all cases of hypertension. Essential hypertension is a heterogeneous disorder, with different patients having different causal factors that lead to high BP. Essential hypertension needs to be separated into various syndromes because the causes of high BP in most patients presently classified as having essential hypertension can be recognized. Known Etiological Factors in Essential HypertensionAlthough it has frequently been indicated that the causes of essential hypertension are not known, this is only partially true because we have little information on genetic variations or genes that are overexpressed or underexpressed as well as the intermediary phenotypes that they regulate to cause high BP.4 A number of factors increase BP, including (1) obesity, (2) insulin resistance, (3) high alcohol intake, (4) high salt intake (in salt-sensitive patients), (5) aging and perhaps (6) sedentary lifestyle, (7) stress, (8) low potassium intake, and (9) low calcium intake.56 Furthermore, many of these factors are additive, such as obesity and alcohol intake. In this review, variations in BP that are genetically determined will be called "inherited BP," although we do not know which genes cause BP to vary; we know from family studies that inherited BP can range from low normal BP to severe hypertension. Factors that increase BP, such as obesity and high alcohol and salt intake, will be called "hyperten-sinogenic factors." Some of these factors have inherited, behavioral, and environmental components. Inherited BP could be considered core BP, whereas hypertensinogenic factors cause BP to increase above the range of inherited BPs, thus creating 4 main possibilities: (1) patients who have inherited BP in the optimal category (<120/<80 mm Hg); if 1 or more hypertensinogenic factors are added, BP would probably increase but remain in the normal range (<135/<85 mm Hg) (Figure 1, first 2 columns); (2) patients who have inherited BP in the normal category (≤130/≤85 mm Hg); if 1 or more hypertensinogenic factors are added, BP will probably increase to the high normal range (130 to 139/85 to 89 mm Hg) or to stage 1 of the hypertensive category (140 to 159/90 to 99 mm Hg) (Figure 1, second 2 columns); (3) patients who have inherited BP in the high normal category (130 to 139/85 to 89 mm Hg); if 1 or more hypertensinogenic factors are added, BP will increase to the hypertensive range (≥140/≥90 mm Hg) (Figure 1, third 2 columns); and (4) patients who have inherited BP in the hypertensive range; addition of 1 or more hypertensinogenic factors will make hypertension more severe, changing it from stage 1 to stage 2 or 3 (Figure 1, fourth to sixth 2 columns).Theoretically, in a population unaffected by hypertensinogenic factors, BP will have a normal distribution; it will be skewed to the right and will have a narrow base or less variance (Figure 2, continuous line). When 1 hypertensinogenic factor is added to this population, such as increased body mass, one would expect the normal distribution curve to be further skewed to the right; consequently the base will be wider (more variance) and the curve will be flatter (Figure 2, broken line). If a second hypertensinogenic factor such as alcohol intake is added to increased body mass, the curve will be skewed more to the right and the variance will increase further, with more subjects classified as hypertensive (Figure 2, dotted line).Discovering which genetic variations place BP on the left or right side of the distribution curve is of both theoretical and practical importance because it could help the physician to better treat or cure hypertension.7 Recognition of the hypertensinogenic factors may allow nonpharmacological prevention, treatment, or cure of hypertension. Hypertensinogenic factors such as obesity, insulin resistance, or high alcohol intake also have an important genetic component. Furthermore, there are interactions between genetic and environmental factors (Figure 2) that influence intermediary phenotypes such as sympathetic nerve activity, the renin-angiotensin-aldosterone and renal kallikrein-kinin systems, and endothelial factors, which in turn influence other intermediary phenotypes such as sodium excretion, vascular reactivity, and cardiac contractility. These and many other intermediary phenotypes determine total vascular resistance and cardiac output and, consequently, BP. Recognition of the hypertensinogenic factor(s) and establishing that the patient's hypertension is the result of obesity (either alone or combined with other factors such as insulin resistance or high alcohol intake) or old age instead of essential hypertension may help the physician as well as the patient and his or her family to modify or eliminate these hypertensinogenic and CVD risk factors when possible, which may cure the hypertension or at least facilitate control of BP. When the hypertensinogenic factor cannot be reduced or eliminated, as with systolic hypertension induced by aging (arteriosclerosis), recognition of the underlying cause of high BP will emphasize the need for (1) further studies to determine whether the patient has arteriosclerosis and/or atherosclerosis, the magnitude of the disease, and whether there are occlusive lesions; (2) treatment of the atherosclerosis with lifestyle and dietary changes and lipid-lowering agents if necessary; and (3) pharmacological treatment of systolic hypertension to decrease passive stiffness (arteriosclerosis) of the major central elastic arteries and decrease morbidity and mortality rates. Thus recognition of factors that induce hypertension is not only of theoretical but also of practical importance. In conclusion, as stated by Beilin,8 "it is no longer appropriate to define essential hypertension as a rise in blood pressure without cause," since a number of causes can be clearly identified in most cases of so-called "essential hypertension." As discussed later in more detail, there is clear evidence that changes in lifestyle, including dietary changes that reduce body weight, fat, and alcohol intake and increase potassium and calcium intake,9 as well as exercise,1011 reduce or normalize BP in many patients. Inherited BPThe identification of variant (allelic) genes that contribute to the development of hypertension is complicated by the fact that the 2 phenotypes that determine BP, cardiac output and total peripheral resistance, are controlled by intermediary phenotypes, including the autonomic nervous system, vasopressor/vasodepressor hormones, the structure of the cardiovascular system, body fluid volume and renal function, and many others. Furthermore, these intermediary phenotypes are also controlled by complex mechanisms including BP itself.12 Thus there are many genes that could participate in the development of hypertension. The influence of genes on BP has been suggested by family studies demonstrating associations of BP among siblings and between parents and children. There is a better association among BP values in biological children than in adopted children and in identical as opposed to nonidentical twins. BP variability attributed to all genetic factors varies from 25% in pedigree studies to 65% in twin studies. Furthermore, genetic factors also influence behavioral patterns, which might lead to BP elevation. For example, a tendency toward obesity or alcoholism will be influenced by both genetic and environmental factors; thus the proportion of BP variability caused by inheritance is difficult to determine and may vary in different populations. Mutations in at least 10 genes have been shown to raise or lower BP through a common pathway by increasing or decreasing salt and water reabsorption by the nephron.1314 The genetic mutations responsible for 3 rare forms of mendelian (monogenic) hypertensive syndromes−glucocorticoid-remediable aldosteronism (GRA), Liddle's syndrome, and apparent mineralocorticoid excess−have been identified, whereas in a fourth, autosomal dominant hypertension with brachydactyly, the gene is not yet identified but has been mapped to chromosome 12 (12p). Subtle variations in one of these genes may also cause some forms of "essential" hypertension. For a review of the mutations that cause a decrease in BP, see Lifton.13Glucocorticoid-Remediable AldosteronismThis is an autosomal dominant form of monogenic hypertension in which aldosterone secretion is regulated by adrenocorticotropic hormone. Glucocorticoid treatment causes BP to decrease and gives the syndrome its name. The genetic mutation that causes GRA has been identified by Lifton14 as a chimeric gene fusing nucleotide sequences of the promoter-regulatory region of 11β-hydroxylase (controlled by adrenocorticotropic hormone) and the structural portion of the aldosterone synthase gene. The chimeric gene results from a meiotic mismatch and unequal crossing over. The patients are usually thought to have primary aldosteronism because they exhibit volume expansion, metabolic alkalosis with hypokalemia, low plasma renin, and high aldosterone. Most of the patients first described as having GRA showed severe hypertension and died prematurely from stroke. However, with the development of direct genetic testing, the BP of patients with this syndrome was found to cover a wide range, including normotensive levels.1516 In patients with GRA and normal BP, expression of the chimeric gene may be variable, but because steroid levels are similar in patients with severe and mild hypertension, this seems unlikely. It is also possible that the genetic background of the trait (other than the chimeric mutation), such as high renal kallikrein, places the inherited BP of these subjects in the low or ideal normal range and the mutation causes BP to increase to high normal or hypertensive stage 1. Thus the final BP would be the combined result of the inherited BP (including the genetic mutation) and the increase in BP caused by hypertensinogenic factors such as salt. Liddle's SyndromeThis is an autosomal dominant form of monogenic hypertension that results from mutations in the amiloride-sensitive epithelial sodium channel, leading to increased channel activity.17 The mutations reported to date result in the elimination of 45 to 75 amino acids from the cytoplasmic carboxyl terminus of β- or γ-subunits of the channel; thus Liddle's syndrome is genetically heterogeneous. It is characterized by the early onset of hypertension with hypokalemia and suppression of both plasma renin activity and aldosterone, the latter differentiating this syndrome from primary aldosteronism. Both the hypertension and the hypokalemia vary in severity, raising the possibility that some patients classified as having salt-sensitive essential hypertension actually have Liddle's syndrome.18 It is also possible that high BP in blacks, who are frequently salt-sensitive, is due to a polymorphism in one of the sodium channel genes or in one of the genes of systems that regulate it, causing its activity to increase. Apparent Mineralocorticoid ExcessThis is an autosomal recessive form of monogenic juvenile hypertension that results from a mutation in the renal-specific isoform 11β-hydroxysteroid dehydrogenase gene.19 Normally this enzyme converts cortisol to the inactive metabolite cortisone. In the distal nephron this is important because cortisol and aldosterone have a similar affinity for the mineralocorticoid receptor. The enzymatic deficiency allows the mineralocorticoid receptors in the nephron to be occupied and activated by cortisol, causing sodium and water retention, volume expansion, low renin, low aldosterone, and more importantly, a salt-sensitive form of hypertension. Thus this gene may be a locus for salt-sensitive essential hypertension. Autosomal Dominant Hypertension With BrachydactylyIn this monogenic syndrome, hypertension and brachydactyly are always inherited together (100% cosegregation).4 Affected persons are shorter than nonaffected relatives. The gene for hypertension has been mapped to the short arm of chromosome 12 (12p) in a large Turkish kindred. Two other families with this syndrome have been reported, 1 in Canada and 1 in the United States. In addition, the study of a Japanese child with hypertension and type E brachydactyly has allowed the area on 12p containing the gene mutation to be pinpointed further, although the gene responsible for this syndrome has not yet been cloned. Unlike the other 3 autosomal forms of hypertension, BP is not affected by volume expansion and the underlying mechanism is not known. Thus identification of the gene responsible may help clarify some of the genetic alterations in essential hypertension. Essential or Primary HypertensionThe genetic alterations responsible for inherited "essential" hypertension remain largely unknown.4 Results from family studies suggest several possible intermediary phenotypes (genetic traits) that may be related to inherited high BP, such as high sodium-lithium countertransport, low urinary kallikrein excretion, high fasting plasma insulin concentrations, high-density LDL subfractions, fat pattern index, and body mass index (BMI).12 Jeunemaitre et al2021 first reported a polymorphism in the angiotensinogen gene linked with essential hypertension in hypertensive siblings from Utah and France. This polymorphism consists of a substitution of thymidine for cytosine in nucleotide 704, which causes substitution of methionine for threonine at position 235 (M235T) and is associated with increased concentrations of plasma angiotensinogen. This variant appears to be in tight linkage disequilibrium with a promoter mutation in which adenine replaces guanine (-6A) upstream from the initiation side of transcription.22 Tests of promoter activity suggest that this nucleotide substitution increases the rate of gene transcription, which may explain the higher angiotensinogen concentration found in subjects with the variant M235T.22 Many studies have been published on various racial groups with regard to the association between allelic variations in angiotensinogen and hypertension.23 However, these variations explain only a small part of the BP variation (≈6%). Furthermore, plasma angiotensinogen concentrations, though higher in patients with the polymorphism, clearly overlap with normotensive patients. Polymorphisms and mutations in other genes such as angiotensin-converting enzyme, β2-adrenergic receptor, α-adducin, angiotensinase C, renin-binding protein, G-protein β3-subunit, atrial natriuretic factor, and the insulin receptor have also been linked to the development of essential hypertension; however, most of them show a weak association if any, and most of these studies need further confirmation. Thus these gene alterations will not be discussed here because they go beyond the scope of this review (see Luft4 ).Hypertensinogenic FactorsThere is evidence that obesity, insulin resistance, high alcohol intake, high salt intake, a sedentary lifestyle, stress, dyslipidemia, and low potassium or calcium intake increase BP in susceptible subjects. Here we will briefly discuss obesity and insulin resistance; other hypertensinogenic factors will be discussed in the section "Lifestyle Modification."Obesity and Insulin ResistanceObesity, and obesity, is the main hypertensinogenic It was estimated in the study that is associated with a mm Hg increase in systolic is also the cause of insulin resistance, left and Thus obesity is an important cardiovascular its incidence and prevalence are in most industrialized and in the United States has The between BP and body fat is not to the but is continuous throughout the range of body A direct association between hypertension and in by the in has been in and population studies from early to old A of is considered normal or whereas a of to with increases the risk of high BP by and the risk of insulin resistance by Thus insulin resistance is in many patients with obesity and hypertension.

Patients with asthma have an underlying chronic inflammation of the airways characterized by activated mast cells, eosinophils, and T-helper 2 lymphocytes. This results in increased responsiveness of the airways to such triggers as exercise, allergens, and air pollutants. This chronic inflammation underlies the typical symptoms of asthma, which include intermittent wheezing, coughing, shortness of breath, and chest tightness.

Use of rumination and activity monitoring for the identification of dairy cows with health disorders: Part I. Metabolic and digestive disorders.
The objectives of this study were to evaluate (1) the performance of an automated health-monitoring system (AHMS) to identify cows with metabolic and digestive disorders-including displaced abomasum, ketosis, and indigestion-based on an alert system (health index score, HIS) that combines rumination time and physical activity; (2) the number of days between the first HIS alert and clinical diagnosis (CD) of the disorders by farm personnel; and (3) the daily rumination time, physical activity, and HIS patterns around CD. Holstein cattle (n=1,121; 451 nulliparous and 670 multiparous) were fitted with a neck-mounted electronic rumination and activity monitoring tag (HR Tags, SCR Dairy, Netanya, Israel) from at least -21 to 80 d in milk (DIM). Raw data collected in 2-h periods were summarized per 24 h as daily rumination and activity. A HIS (0 to 100 arbitrary units) was calculated daily for individual cows with an algorithm that used rumination and activity. A positive HIS outcome was defined as a HIS of <86 during at least 1 d from -5 to 2 d after CD. Blood concentrations of nonesterified fatty acids, β-hydroxybutyrate, total calcium, and haptoglobin were determined in a subgroup of cows (n=459) at -11±3, -4±3, 0, 3±1, 7±1, 14±1, and 28±1 DIM. The sensitivity of the HIS was 98% [95% confidence interval (CI): 93, 100] for displaced abomasum (n=41); 91% (95% CI: 83, 99) for ketosis (n=54); 89% (95% CI: 68, 100) for indigestion (n=9); and 93% (95% CI: 89, 98) for all metabolic and digestive disorders combined (n=104). Days (mean and 95% CI) from the first positive HIS <86 and CD were -3 (-3.7, -2.3), -1.6 (-2.3, -1.0), -0.5 (-1.5, 0.5), and -2.1 (-2.5, -1.6) for displaced abomasum, ketosis, indigestion, and all metabolic and digestive disorders, respectively. The patterns of rumination, activity, and HIS for cows flagged by the AHMS were characterized by lower levels than for cows without a health disorder and cows not flagged by the AHMS from -5 to 5 d after CD, depending on the disorder and parameter. Differences between cows without health disorders and those flagged by the AHMS for blood markers of metabolic and health status confirmed the observations of the CD and AHMS alerts. The overall sensitivity and timing of the AHMS alerts for cows with metabolic and digestive disorders indicated that AHMS that combine rumination and activity could be a useful tool for identifying cows with metabolic and digestive disorders.

Lin SL. (2023)MEDLINE-indexed journal, not yet read by usJournal of affective disorders The "loneliness epidemic", intersecting risk factors and relations to mental health help-seeking: A population-based study during COVID-19 lockdown in Canada.
Background: Pandemic-induced social distancing and stay-at-home orders, while successful in decreasing the transmission of COVID-19, could exacerbate loneliness. Few studies have examined how pandemic-related social determinants intersect to shape pandemic loneliness and its relations to mental health care in Canada.
Methods: A population-representative sample of 3772 adults from the Canadian Perspective Survey Series (CPSS-6; January 25 to 31, 2021) was analyzed. Gender-specific logistic regression was employed to investigate the association between three-item loneliness scale (UCLA-3) with socio-demographics, job precarity, health behaviours, social isolation indicators, and mental health help-seeking. Classification and Regression Tree (CART) modelling was used to identify intersecting risk factors and the most important predictor of severe loneliness (UCLA-3 score ≥ 7).
Results: The estimated prevalence of severe loneliness was 34.7 % in Canada, with women significantly higher than men (38.1 % vs 31.3 %, p < 0.001). Pandemic loneliness were more prevalent in female (OR = 1.53, 99 % CI: 1.26-1.85), those who were younger (OR's range 1.42-3.00), women without college degree (OR = 1.44, 99 % CI: 1.01-2.04), those living alone (OR = 1.56, 99 % CI: 1.09-2.23), immigrant men (OR = 1.79, 99 % CI: 1.23-2.60), those with small network (OR's range: 1.73-3.26), those who were absent from work due to COVID-19 related reasons (OR = 2.11, 99 % CI: 1.04-4.28), past-month binge drinkers (OR's range: 1.39-1.70) and cannabis user (OR = 1.47, 99 % CI: 1.12-1.93). The CART algorithm identifies that immigrants who experienced pandemic-triggered job insecurity were the most-at-risk group of severely loneliness. Pandemic loneliness was positively associated with formal help-seeking from mental health professionals (OR = 1.71, 99 % CI: 1.21-2.41), informal help-seeking from social circle (OR = 1.51, 99 % CI: 1.17-1.95), and unmet mental health needs (OR = 1.78, 99 % CI: 1.29-2.49).
Limitations: Cross-sectional data prohibits causal inferences.
Conclusion: The COVID-19 pandemic converges with loneliness epidemic in Canada. Prevention and intervention programs should target upstream social determinants of mental health, especially the intersection of migration status and COVID-19-related job precarity, to eliminate loneliness during the pandemic.

Psychological mechanisms associated with food security status and BMI in adults: a mixed methods study.
Objective: This study examined psychological constructs (delay discounting, grit, future time perspective and subjective social status) in relation to food security status and body weight.
Design: A simultaneous triangulation mixed methods design was used to collect quantitative and qualitative data. Quantitative data were collected in fifty-six adults. Independent variables included food security status (food secure or food insecure) and BMI category (normal weight or overweight/obese). Participants, matched on race (African American and White), were categorised into four food security status by BMI category groups. Psychological constructs were measured via validated questionnaires. Qualitative data were collected in a subsample of twelve participants via in-depth interviews.
Setting: This study was conducted in Baton Rouge, Louisiana.
Participants: The sample was 66 % female and 48 % African American with a mean age of 32·3 (sd 9·2) years and BMI of 28·8 (sd 7·7) kg/m2.
Results: Quantitative results showed that food-insecure participants with overweight/obesity had greater delay discounting (-3·78 v. -6·16, P = 0·01; -3·78 v. -5·75, P = 0·02) and poorer grit (3·37 v. 3·99, P = 0·02; 3·37 v. 4·02, P = 0·02 ) than their food-secure counterparts and food-insecure participants with normal weight. Food-insecure participants with overweight/obesity also had a shorter time period for financial planning (0·72 v. 4·14, P = 0·02) than food-secure participants with normal weight. Qualitative data largely supported quantitative findings with participants discussing varied perceptions of psychological constructs.
Conclusions: This study found differences in delaying gratification, grit and financial planning between food security status and body weight groups.

Time-varying associations of pre-migration and post-migration stressors in refugees' mental health during resettlement: a longitudinal study in Australia.
Background: Understanding the time-varying association of pre-migration and post-migration stressors in refugees' mental health could help in designing tailored health promotion services at different resettlement stages and improving the efficiency of resource allocation. In this study, we explored these time-varying associations.
Methods: We used data from the first four waves (October, 2013, to February, 2017) of a national refugee-based longitudinal study, the Building a New Life in Australia (BNLA) project. Post-traumatic stress disorder (PTSD) and high risk of severe mental illness (HR-SMI) were used to assess mental health. The independent variables included the number of potentially traumatic events experienced during the pre-migration process, and a range of post-migration stressors. We used logistic regression models to analyse the relative importance of variables and time-varying associations between the pre-migration potentially traumatic events, post-migration resettlement stressors, and refugees' mental health. Analyses were stratified by gender, and sociodemographic covariates included age, marital status, education level, country of birth, and weekly income.
Results: 2399 participants were surveyed in Wave 1 of the BNLA project in 2013-14, of whom 2009 (83·7%) responded in Wave 2 in 2014-15, 1894 (78·9%) in Wave 3 in 2015-16, and 1929 (80·4%) in Wave 4 in 2016-17. The three most important factors associated with mental health in each wave differed for male and female refugees, but the socioeconomic stressors of loneliness and adjustment to life in Australia were consistently prominent. Positive associations between socioeconomic stressors and mental ill-health were found for both genders, with a peak at Wave 2 (adjusted odds ratio [AOR] among men, 1·60 [95% CI 1·26-2·03], p=0.0001 for PTSD; AOR 1·86 [1·35-2·55], p=0·0001 for HR-SMI; and among women, AOR 1·81 [1·27-2·57], p=0·0009 for PTSD; AOR 2·24 [1·49-3·38], p=0·0001 for HR-SMI). Associations between loneliness and mental health fluctuated, but were significant for both genders in Wave 4 (among men, AOR 1·90 [1·21-2·99], p=0·0051 for PTSD; AOR 3·70 [2·18-6·27], p<0·0001 for HR-SMI; and among women, AOR 3·65 [2·08-6·39], p<0·0001 for PTSD; AOR 3·68 [2·02-6·69], p<0·0001 for HR-SMI). The association between difficulties in adjustment to life in Australia and male refugees' mental ill-health increased continuously during the resettlement period.
Interpretation: Gender-specific and time-sensitive services should be considered to improve refugees' mental health. For both genders, improved economic conditions that complement social security benefits deserve attention and are relevant throughout the resettlement process. At the later stage of resettlement, services to reduce loneliness could be carried out, and reducing stressors related to adjustment to life in the host country is especially needed for male refugees.

Roles of cyberbullying, sleep, and physical activity in mediating the effects of social media use on mental health and wellbeing among young people in England: a secondary analysis of longitudinal data.
Background: There is growing concern about the potential associations between social media use and mental health and wellbeing in young people. We explored associations between the frequency of social media use and later mental health and wellbeing in adolescents, and how these effects might be mediated.
Methods: We did secondary analyses of publicly available data from the Our Futures study, a nationally representative, longitudinal study of 12 866 young people from age 13 years to 16 years in England. The exposure considered was the frequency of social media use (from weekly or less to very frequent [multiple times daily]) at wave 1 (participants aged 13-14 years) through wave 3 of the study (participants aged 15-16 years). Outcomes were mental health at wave 2 (with high 12-item General Health Questionnaire [GHQ12] scores [≥3] indicating psychological distress), and wellbeing at wave 3 (life satisfaction, feeling life is worthwhile, happiness, and anxiety, rated from 1 to 10 by participants). Analyses were adjusted for a minimal sufficient confounding structure, and were done separately for boys and girls. Cyberbullying, sleep adequacy, and physical activity were assessed as potential mediators of the effects.
Findings: Very frequent use of social media increased from wave 1 to wave 3: from 34·4% (95% CI 32·4-36·4) to 61·9% (60·3-63·6) in boys, and 51·4% (49·5-53·3) to 75·4% (73·8-76·9) in girls. Very frequent social media use in wave 1 predicted a high GHQ12 score at wave 2 among girls (adjusted odds ratio [OR] 1·31 [95% CI 1·06-1·63], p=0·014; N=4429) and boys (1·67 [1·24-2·26], p=0·0009; N=4379). Persistent very frequent social media use across waves 1 and 2 predicted lower wellbeing among girls only (adjusted ORs 0·86 [0·74-0·99], N=3753, p=0·039 for life satisfaction; 0·80 [0·70-0·92], N=3831, p=0·0013 for happiness; 1·28 [1·11-1·48], N=3745, p=0·0007 for anxiety). Adjustment for cyberbullying, sleep, and physical activity attenuated the associations of social media use with GHQ12 high score (proportion mediated 58·2%), life satisfaction (80·1%), happiness (47·7%), and anxiety (32·4%) in girls, such that these associations (except for anxiety) were no longer significant; however, the association with GHQ12 high score among boys remained significant, being mediated only 12·1% by these factors.
Interpretation: Mental health harms related to very frequent social media use in girls might be due to a combination of exposure to cyberbullying or displacement of sleep or physical activity, whereas other mechanisms appear to be operative in boys. Interventions to promote mental health should include efforts to prevent or increase resilience to cyberbullying and ensure adequate sleep and physical activity in young people.

Dapivirine vaginal ring for HIV prevention: modelling health outcomes, drug resistance and cost-effectiveness.
Introduction: A vaginal ring containing dapivirine is effective for HIV prevention as pre-exposure prophylaxis (PrEP). We evaluated the potential epidemiological impact and cost-effectiveness of dapivirine vaginal ring PrEP among 22- to 45-year-old women in KwaZulu-Natal, South Africa.
Methods: Using mathematical modelling, we studied dapivirine vaginal ring PrEP implementation, either unprioritized, or prioritized based on HIV incidence (≥3% per year), age (22 to 29 years) or female sex worker status, alongside the implementation of voluntary medical male circumcision and antiretroviral therapy scaled-up to UNAIDS Fast-Track targets. Outcomes over the intervention (2019 to 2030) and lifetime horizons included cumulative HIV infections, life-years lived, costs and cost-effectiveness. We assessed the incremental cost-effectiveness ratios against the revealed willingness to pay ($500) and the standard (2017 per capita gross domestic product; $6161) cost-effectiveness thresholds for South Africa.
Results: Compared to a reference scenario without PrEP, implementation of dapivirine vaginal ring PrEP, assuming 56% effectiveness and covering 50% of 22 to 29-year-old or high-incidence women, prevented 10% or 11% of infections by 2030 respectively. Equivalent, unprioritized coverage (30%) prevented fewer infections (7%), whereas 50% coverage of female sex workers had the least impact (4%). Drug resistance attributable to PrEP was modest (2% to 4% of people living with drug-resistant HIV). Over the lifetime horizon, dapivirine PrEP implementation among female sex workers was cost-saving, whereas incidence-based PrEP cost $1898 per life-year gained, relative to PrEP among female sex workers and $989 versus the reference scenario. In a scenario of 37% PrEP effectiveness, PrEP had less impact, but prioritization to female sex workers remained cost-saving. In uncertainty analysis, female sex worker PrEP was consistently cost-saving; and over the lifetime horizon, PrEP cost less than $6161 per life-year gained in over 99% of simulations, whereas incidence- and age-based PrEP cost below $500 per life-year gained in 61% and 49% of simulations respectively. PrEP adherence and efficacy, and the effectiveness of antiretroviral therapy for HIV prevention, were the principal drivers of uncertainty in the cost-effectiveness of PrEP.
Conclusions: Dapivirine vaginal ring PrEP would be cost-saving in KwaZulu-Natal if prioritized to female sex workers. PrEP's impact on HIV prevention would be increased, with potential affordability, if prioritized to women by age or incidence.

Single-arm trial of the second version of an acceptance & commitment therapy smartphone application for smoking cessation.
Background: The first randomized trial of a smartphone application (app) for adult smoking cessation (SmartQuit 1.0) revealed key features that predict cessation. These findings guided the revision of this Acceptance & Commitment Therapy (ACT)-based application (SmartQuit 2.0), which was primarily tested to examine participant receptivity, short-term cessation and reduction, and the relationship between program completion, smoking cessation and reduction. Secondarily, outcomes were descriptively compared with the SmartQuit1.0 trial.
Method: Adult participants (78% female, 25% with high school or less education, 30% unemployed) were recruited into the single-arm pilot trial (N=99) of SmartQuit 2.0 with a two-month follow-up (85% retention).
Results: Regarding receptivity, 84% of participants were satisfied with SmartQuit 2.0 (vs. 59% for SmartQuit1.0), 73% would recommend it to a friend (vs. 48% for SmartQuit1.0), 81% found the ACT exercises useful for quitting (vs. 44% for SmartQuit1.0). At the 2-month follow-up, the quit rates were 21% for 7-day point prevalence (vs. 23% for SmartQuit1.0), 11% for 30-day point prevalence (vs. 13% for SmartQuit1.0), and 75% of participants reduced their smoking frequency (vs. 57% for SmartQuit1.0). Among program completers (24% of total sample), the quit rates were 33% for 7-day point prevalence, 28% for 30-day point prevalence, and 88% of participants reduced their smoking frequency.
Conclusions: The revised app had high user receptivity, modest quit rates, and high smoking reduction rates. Program completion may be key to boosting the app's effectiveness.

Schwartz SR, Nowak RG, Orazulike I, Keshinro B, Ake J, Kennedy S, Njoku O, Blattner WA, Charurat ME, Baral SD, TRUST Study Group. (2015)MEDLINE-indexed journal, not yet read by usThe lancet. HIV The immediate eff ect of the Same-Sex Marriage Prohibition Act on stigma, discrimination, and engagement on HIV prevention and treatment services in men who have sex with men in Nigeria: analysis of prospective data from the TRUST cohort.
Background: In January, 2014, the Same-Sex Marriage Prohibition Act was signed into law in Nigeria, further criminalising same-sex sexual relationships. We aimed to assess the immediate effect of this prohibition act on stigma, discrimination, and engagement in HIV prevention and treatment services in men who have sex with men (MSM) in Nigeria.
Methods: The TRUST cohort study uses respondent-driven sampling to assess the feasibility and effectiveness of engagement of MSM in HIV prevention and treatment services at a clinical site located with a community-based organisation trusted by the MSM community. TRUST is a prospective implementation research cohort of MSM (≥16 years) in Abuja, Nigeria. We compared HIV clinical outcomes and stigma, including fear and avoidance of health care, across baseline and quarterly visits before and after implementation of the the Same-Sex Marriage Prohibition Act. Outcomes assessed were measures of stigma and discrimination, loss to follow-up, antiretroviral therapy status, and viral load. We compared outcomes before and after the legislation with χ2 statistics, and estimated incident stigma-related events and loss to follow-up with Poisson regression.
Findings: Between March 19, 2013, and Aug 7, 2014, 707 MSM participated in baseline study procedures, contributing to 756 before legislation (prelaw) and 420 after legislation (postlaw) visits. Reported history of fear of seeking health care was significantly higher in postlaw visits than in prelaw visits (n=161 [38%] vs n=187 [25%]; p<0・0001), as was avoidance of health care (n=118 [28%] vs n=151 [20%]; p=0・001). In incidence analyses, of 192 MSM with follow-up data and no history of an event at baseline, reported fear of seeking health care was higher in the postlaw than the prelaw period (n=144; incidence rate ratio 2・57, 95% CI 1・29–5・10; p=0・007); loss to follow-up and incident healthcare avoidance were similar across periods. Of the 161 (89%) of 181 HIV-infected MSM with HIV viral loads available, those who had disclosed sexual behaviour with a health-care provider were more often virally suppressed at baseline than those with no previous disclosure (18 [29%] of 62 vs 13 [13%] of 99 men; p=0・013).
Interpretation: These analyses represent individual-level, quantitative, real-time prospective data for the health-related effects resulting from the enactment of legislation further criminalising same-sex practices. The negative effects of HIV treatment and care in MSM reinforce the unintended consequences of such legislation on global goals of HIV eradication. Strategies to reach MSM less likely to engage in HIV testing and care in highly stigmatised environments are needed to reduce time to HIV diagnosis and treatment.

Volunteering and Changes in Cardiovascular Biomarkers: Longitudinal Evidence From the Health and Retirement Study.
Background and objectives: Growing body of research shows that volunteering is beneficial for those served, the volunteers, and the larger communities. However, major challenges remain that hinder the practical implications for volunteer activity as a public health intervention, including potential selection effects, lack of longitudinal studies that adjust for baseline characteristics, and a paucity of studies that consider multiple physical health outcomes in a single model.
Research design and methods: Data from 2006 to 2016 waves of the Health and Retirement Study (2006-2016) were used (N = 18,847). Outcome-wide analyses were utilized to evaluate if changes in volunteering between 2006/2008 (t0) and 2010/2012 (t1) were associated with 7 cardiovascular disease biomarkers 4 years later (2014/2016, t2). These models were adjusted for demographic factors, socioeconomic status, health behaviors, chronic conditions, baseline biomarkers, and volunteering. Additionally, selection into volunteering and attrition were taken into account.
Results: Compared with nonvolunteers, volunteering more than 200 hr a year was associated with a lower risk for clinically high diastolic blood pressure. In addition, increased volunteering effort (change from 1 to 99 hr at t0 to >100 hr at t1) was associated with a lower likelihood of clinically high systolic and diastolic blood pressure levels. Sustained high volunteering (>100 hr at both t0 and t1) was associated with lower diastolic blood pressure.
Discussion and implications: The current study adds to the evidence on the health benefits of volunteering for adults 50 and older by inferring a potential causal link between high-intensity volunteering and reduced blood pressure.

Factors Associated with Smoking Cessation in Pregnancy.
Objective The objective of this study was to quantify the influence of various patient characteristics on early smoking cessation to better identify target populations for focused counseling and interventions. Study Design This study was a population-based retrospective cohort study of 1,003,532 Ohio live births more than 7 years (2006-2012). Women who quit smoking in the first trimester were compared with those who smoked throughout pregnancy. Logistic regression estimated the strength of association between patient factors and smoking cessation. Results The factors most strongly associated with early smoking cessation were non-white race and Hispanic ethnicity, at least some college education, early prenatal care, marriage, and breastfeeding. Numerous factors commonly associated with adverse perinatal outcomes were found to have a negative association with smoking cessation: low educational attainment, limited or late prenatal care, prior preterm birth, age < 20 years, age ≥ 35 years, and indicators of low SES. In addition, the heaviest smokers (≥ 20 cigarette/day) were least likely to quit (adjusted relative risk [RR], 0.35; 95% confidence interval 0.34, 0.36). Conclusion Early prenatal care and initiation of breastfeeding before discharge from the hospital are associated with increased RR of quitting early in pregnancy by 52 and 99%, respectively. Public health initiatives and interventions should focus on the importance of early access to prenatal care and education regarding smoking cessation for these particularly vulnerable groups of women who are at inherently high risk of pregnancy complications.

Association of Short and Long Sleep Duration With Amyloid-β Burden and Cognition in Aging.
Importance: Disrupted sleep is common in aging and is associated with cognition. Age-related changes to sleep are associated with multiple causes, including early Alzheimer disease pathology (amyloid β [Aβ]), depression, and cardiovascular disease.
Objective: To investigate the associations between self-reported sleep duration and brain Aβ burden as well as the demographic, cognitive, and lifestyle variables in adults with normal cognition.
Design, setting, and participants: This cross-sectional study obtained data from participants in the Anti-Amyloid Treatment in Asymptomatic Alzheimer's Disease (A4) study, which is being conducted in 67 sites in the United States, Canada, Australia, and Japan. The sample for this analysis consisted of individuals aged 65 to 85 years who underwent an Aβ positron emission tomography (PET) scan, had complete apolipoprotein E (APOE) genotype data, and were identified as clinically normal (per a Clinical Dementia Rating score of 0) and cognitively unimpaired (per a Mini-Mental State Examination score of 25 to 30 and Logical Memory Delayed Recall test score of 6 to 18). Data were analyzed from April 3, 2020, to June 20, 2021.
Main outcomes and measures: The outcome was self-reported nightly sleep duration (grouped by short sleep duration: ≤6 hours, normal sleep duration: 7-8 hours, and long sleep duration: ≥9 hours) compared with demographic characteristics, Aβ burden (as measured with a fluorine 18-labeled-florbetapir PET scan), objective and subjective cognitive function measures, and lifestyle variables.
Results: The 4417 participants in the study included 2618 women (59%) and had a mean (SD) age of 71.3 (4.7) years. Self-reported shorter sleep duration was linearly associated with higher Aβ burden (β [SE] = -0.01 [0.00]; P = .005), and short sleep duration was associated with reduced cognition that was mostly in memory domains. No difference in Aβ was found between long and normal sleep duration groups (β [SE] = 0.00 [0.01]; P = .99). However, compared with normal sleep duration, both short and long sleep durations were associated with higher body mass index (short vs normal sleep duration: β [SE] = 0.48 [0.17], P = .01; long vs normal sleep duration: β [SE] = 0.97 [0.31], P = .002), depressive symptoms (short vs normal sleep duration: β [SE] = 0.31 [0.05], P < .001; long vs normal sleep duration: β [SE] = 0.39 [0.09], P < .001), and daytime napping (short vs normal sleep duration: β [SE] = 2.66 [0.77], P = .001; long vs normal sleep duration: β [SE] = 3.62 [1.38], P = .01). Long sleep duration was associated with worse performance across multiple cognitive domains.
Conclusions and relevance: In this cross-sectional study, both short and long sleep durations were associated with worse outcomes for older adults, such as greater Aβ burden, greater depressive symptoms, higher body mass index, and cognitive decline, emphasizing the importance of maintaining adequate sleep.

Risk factors for non-suicidal self-injury (NSSI) in adolescents: A meta-analysis.
Background: Non-suicidal self-injury (NSSI) in adolescents is a significant mental health problem around the world. Here, we performed a meta-analysis to systematically delineate the risk factors for NSSI.
Method: We searched Medline, Embase, Web of Science and Cochrane for relevant articles and abstracts published prior to 12 November 2021. Pooled odds ratios (ORs) and 95% confident intervals (CIs) were used to assess various risk factors, and publication bias was assessed by Egger's test, the trim and fill method and meta-regression. This study is registered with PROSPERO, CRD42021265885.
Results: A total of 25 articles were eventually included in the analysis. Eighty risk factors were identified and classified into 7 categories: mental disorders (ORs, 1·89; 95% CI, 1·60-2·24), bullying (ORs, 1·98; 95% CI, 1·32-2·95), low health literacy (ORs, 2·20; 95% CI, 1·63-2·96), problem behaviours (ORs, 2·36; 95% CI, 2·00-2·77), adverse childhood experiences (ORs, 2·49; 95% CI, 1·85-3.34), physical symptoms (ORs, 2·85; 95% CI, 1·36-5·97) and the female gender (ORs, 2·89; 95% CI, 2·43-3·43). The range of heterogeneity (I2) was from 20·3% to 99·2%.
Conclusion: This meta-analysis found that mental disorders, low health literacy, adverse childhood experiences, bullying, problem behaviours, the female gender and physical symptoms appear to be risk factors for NSSI.

Antecedents and sequelae of sudden parental death in offspring and surviving caregivers.
Objectives: To examine the psychiatric antecedents that put parents at risk for early death, and the psychological sequelae of bereavement in offspring and caregivers.
Design: A population-based study.
Setting: Bereaved families were recruited through the coroner's records and by advertisement. Control families were recruited by random-digit dialing and advertisement.
Participants: Families with biological offspring from 7 to 25 years of age in which 1 parent died of suicide, accident, or sudden natural death were included (n = 140). Controls (n = 99) had 2 living parents and their biological offspring and had no death of a first-degree relative within the past 2 years.
Main outcome measures: Lifetime psychiatric history for deceased parents (probands) and new-onset psychiatric disorders, self-reported symptoms, and functional status in offspring and surviving caregivers.
Results: Bipolar disorder, substance abuse, and personality disorders are more common in probands who died of suicide or accident than in control parents. Bereaved offspring and their caregivers were at increased risk for depression and posttraumatic stress disorder. Bereaved offspring had a 3-fold (95% confidence interval, 1.3-7.0) increased risk of depression, even after controlling for antecedent and concomitant risk factors. Offspring bereaved by suicide showed similar outcomes compared with those bereaved by other types of death.
Conclusions: Bereavement conveys an increased risk of depression and posttraumatic stress disorder above and beyond other vulnerability factors. Better integration of medical and psychiatric care may prevent premature parental death, but once it occurs, physicians should be alert to the increased risk for depression and posttraumatic stress disorder in bereaved offspring and their caregivers.

Childhood behavior problems and health at midlife: 35-year follow-up of a Scottish birth cohort.
Background: Childhood behavior problems are associated with premature mortality. To identify plausible pathways that may account for this association, we explored the extent to which childhood behavior problems relate to health behaviors and health outcomes at midlife.
Methods: The Aberdeen Children of the 1950s (ACONF) study comprises 12,500 children from the Aberdeen area, Scotland, UK. Childhood behavior problems were assessed by teacher ratings at children's age of 6-12 years. Between 2001 and 2003, surviving study members, then aged 46-51 years, were mailed a questionnaire containing enquiries about physician-diagnosed conditions (long-term disease, diabetes, high blood pressure), general health, well-being, weight, smoking, and alcohol intake. A total of 7,183 responded.
Results: Two dimensions of externalizing (conduct problems and hyperactivity) and one of internalizing (emotional problems) behaviors were associated with adult health. Childhood conduct problems were related to an increased risk of long-term disease (odds ratio per one standard deviation increase; 95% confidence interval: 1.15; 1.02-1.29 for men; 1.26; 1.08-1.47 for women), obesity (1.16; 1.01-1.33 in men; 1.38; 1.14-1.68 in women), cigarette smoking (1.20; 1.07-1.34 in men; 1.17; 1.01-1.35 in women), and lower well-being. Childhood hyperactivity was associated with earlier initiation of smoking in men and women; smoking more cigarettes in women; and binge-drinking, as well as a higher frequency of hangovers in men. Internalizing behavior was related to a reduced the risk of ever smoking (.87; .80-.95 in men; .92; .85-.99 in women) and to healthier drinking patterns. In women but not men, internalizing problems also predicted a later age of smoking onset. Adjusting for socio-economic status of origin, childhood intelligence, education and age had negligible effects on these results.
Conclusions: Childhood behavior problems were associated with a series of adult health-related habits that may partially account for the link between early problem behaviors and premature mortality.

Screening for depression and anxiety disorders from pregnancy to postpartum with the EPDS and STAI.
The Edinburgh Postnatal Depression Scale (EPDS) and the State Anxiety Inventory (STAI-S) are widely used self-report measures that still need to be further validated for the perinatal period. The aim of this study was to examine the screening performance of the EPDS and the STAI-S in detecting depressive and anxiety disorders at pregnancy and postpartum. Women screening positive on EPDS (EPDS ≥ 9) or STAI-S (STAI-S ≥ 45) during pregnancy (n = 90), as well as matched controls (n = 58) were selected from a larger study. At 3 months postpartum, 99 of these women were reassessed. At a second stage, women were administered a clinical interview to establish a DSM-IV-TR diagnosis. Receiver operator characteristics (ROC) analysis yielded areas under the curve higher than .80 and .70 for EPDS and STAI-S, respectively. EPDS and STAI-S optimal cut-offs were found to be lower at postpartum (EDPS = 7; STAI-S = 34) than during pregnancy (EPDS = 9; STAI-S = 40). EPDS and STAI-S are reasonably valid screening tools during pregnancy and the postpartum.

Does Improving Medical Record Documentation Better Reflect Severity of Illness in Neurosurgical Patients?
Physician documentation in the medical record is essential for communicating the clinical status and care plan to other healthcare providers. The medical record also serves as a medicolegal document to protect the physician should medical malpractice be alleged. In addition to these uses, documentation of patients' diagnoses and procedures is used by hospital coders to calculate severity of illness (SOI) and risk of mortality (ROM) ratings. A rating given from level 1 to 4 (4 being most severe), SOI reflects a patient's degree of physiological illness. Also scored from 1 to 4, ROM is a gauge of the patient's risk of death while in the hospital on the basis of the patient's diagnoses (Table 1).TABLE: 1. Severity of Illness and Risk of Mortality Grading SystemsBoth SOI and ROM have significant roles in healthcare economics. Hospital reimbursement depends in part on SOI. The Centers for Medicare and Medicaid Services (CMS) is the entity of the federal government that is responsible for healthcare financing, coverage, and payment of Medicare and Medicaid beneficiaries. Formerly known as the Health Care Financing Administration, CMS adopted diagnosis-related groups (DRGs) in 1983 after their development at Yale University in 1970. Their purpose was to replace the traditional per-diem method of hospital reimbursement. Per diems were cost based and characterized as an undifferentiated patient day regardless of patient illness. In contrast, each DRG classification represents similar resource consumption and length-of-stay patterns so that reimbursement is based on these expectations. In 2008, the CMS went one step further and added a severity-adjusted version to the original DRGs called Medicare-severity DRG.1 The severity adjustment takes into account the patient's SOI and is now used by the Medicare Inpatient Prospective Payment System. The SOI and ROM scores are also being used to gauge quality control issues. Data for every Medicare inpatient stay are maintained in the Medicare Provider and Analysis Review file.2 Quality improvement organizations contracted by CMS to provide quality oversight to Medicare providers use the data to assess potential problems with noncompliance. Additionally, these organizations analyze a facility's Medicare-severity DRG mix to look for problems with hospitals that may potentially always code for higher-weighted DRGs and appear as outliers compared with other similar facilities.3 Finally, “quality of care” assessments use SOI and ROM. Mortality rates vary between providers and hospitals; the presumption is that after controlling for patients' severity of illness, residual differences in mortality rates relate to differences in quality of care. Corporations such as Thompson Reuters have created a marketing tool and “status” based on this information that hospitals may strive to achieve. The well-known “Top 100 Hospitals”4 lists the 100 “best” hospitals across the country in a given specialty line. When the results of the Hospital Consumer Assessment of Healthcare Providers and Systems survey5 are compared between winners of the Top 100 Hospitals award and nonwinners, the award winners do slightly better than nonwinners on all survey items that showed modest but statistically significant differences between the 2 groups.6 These findings suggest that marketing tools such as the Top 100 Hospitals might play a role in consumer perception, assessment, and decision making. All-patient-refined DRGs (APR-DRGs) are another mode for comparison. Trademarked by 3M, APR-DRGs classify all inpatient admissions based on the SOI and ROM levels represented by International Classification of Disease, ninth revision (ICD-9), codes. Institutions such as the Agency for Healthcare Research and Quality are using APR-DRGs for quality monitoring purposes, especially for severity adjustment of mortality rates.1 The SOI and ROM are derived from documentation of patients' diagnoses and comorbidities.1,7 Errors in documentation can lead to overestimation or underestimation of expected mortality, which has an effect on an institution's comparison with other hospitals.8,9 Furthermore, neurosurgeons contribute significantly to hospitals' financial health.10,11 Better documentation of admitting diagnoses and comorbidities should enable more accurate ICD-9 coding, which in turn should lead to more accurate calculation of SOI and ROM. The rationale for the study stemmed from a need for resident participation in a quality improvement project, a requirement dictated by the Accreditation Council of Graduate Medical Education.12 Before the project, a preliminary review of progress notes on the neurosurgery service by one of the authors (N.S.L.) indicated suboptimal documentation of patient comorbidities. The objective of this study was to determine whether interventions designed to effectively improve physician clinical documentation would subsequently lead to increased capture of SOI and ROM. A secondary aim of the project was to simultaneously provide residents with a quality improvement opportunity. We hypothesize that the multimodality interventions that improve neurosurgeons' clinical documentation lead to better characterization of SOI and ROM. MATERIALS AND METHODS Documentation Improvement Interventions Before data collection, 3 specific interventions were used to educate physicians with the goal of improving medical record documentation as part of the master's thesis of one of the authors (C.H.). These modalities included the following: group in-service, development and use of a progress note template, and concurrent medical record coder review and feedback to the physician during the patients' in-hospital stays. Faculty and residents in the Division of Neurological Surgery at University of Missouri Hospitals and Clinics participated in a 30-minute in-service on coding, SOI, and ROM. A new neurosurgery progress note template (Figure 1) was introduced, and instructions for its use were provided. The template was organized to include comorbidities listed as ICD-9 codes and grouped into organ system for ease of location.FIGURE 1: Neurosurgery progress note. Mechanisms for queries to the physicians from the nurse reviewer and appropriate responses were explained to the group. Informed consent was obtained from the participating physicians. The study was approved by the Health Sciences Institutional Review Board. After the in-service, a nurse-reviewer (working in the capacity of assistant manager of medical records) began random review of neurosurgical patient records. Random record review was performed 2 to 3 times per week, averaging 10 to 15 h/wk, while patients were still hospitalized to look for potential diagnoses that were not appropriately documented. Charts for review were chosen at random; however, intensive care unit patients were given priority for review over floor patients. Information gathered was kept on a worksheet (Figure 2), and cases for which questions existed were e-mailed to the physicians with a copy to the senior author (N.S.L). A typical query follows: “Patient X, MNICU 13, had a 3400cc EBL during OR, and received several units of PRBCx and FFP. H&H dropped from 12.1/35.2 to 5.9/17. Would a secondary diagnosis of acute blood loss anemia be appropriate? If so, please document in the progress notes.”FIGURE 2: Clinical documentation review tool. Follow-up on queries was completed to determine whether the physician had documented the diagnosis in question. If no response was made, a second e-mail was sent. In cases when the patient had been discharged and confirmation or disagreement with the query was not documented in the progress notes as requested, an e-mail notification was sent, asking the physician to address the query in the discharge summary. This method of review, queries by e-mail, and rereview occurred for 8 weeks. Data Collection All neurosurgery service adult in-patient charts at University of Missouri Hospital and Clinics were retrospectively reviewed from 3 time intervals. June 2004 to December 2004 represented the preintervention period. August 2007 to December 2007 was the time period during active educational intervention. Finally, June 2008 to December 2008 represented the postintervention period. Data collected included patient age, sex, ICD-9 diagnoses, raw patient mortality, SOI, and ROM. Patients younger than 18 years of age at the time of admission were excluded. Versions 24 and 25 of the 3M APR-DRGs13,14 were used to calculate ROM and SOI. Preliminary data were pulled from each time period and analyzed according to the description below. From the results of the preliminary data analysis, the standard deviation for the SOI and ROM outcomes was estimated to be about 1.0 units. It was determined that sample sizes of 300 patients per time period would give well over 80% power for detecting differences in mean scores of 0.25 units. The estimated power was found using the POWER procedure in SAS version 9 (SAS Institute Inc, Cary, North Carolina). Data Analysis The outcomes of mortality, SOI, and ROM can all be influenced by a patient's age, sex, and primary diagnosis. Consequently, analyses were done to determine whether any of these variables differed between time periods. Furthermore, these variables were considered covariates when testing the primary outcomes for differences between time periods. Primary diagnoses were grouped into 9 categories based on ICD-9 codes as follows: malignant neoplasms, benign neoplasms, nervous system disorders, cardiovascular disease, musculoskeletal disorders, skull/spine injuries, brain contusions, complications, and other diagnoses. The Kruskal-Wallis test was used to test for differences in age between time periods. Sex differences were assessed with a χ2 model. Stratification or adjustment for differences in age and sex was performed with the Cochran-Mantel-Haenszel test. For the prediction of the probability of occurrence of mortality, logistic regression was used. Finally, the cumulative logit model was used to analyze SOI and ROM, taking into account differences in primary diagnoses over time. The SAS Analytical Software version 9.0 was used for the analysis. In view of the fact that preliminary data were reanalyzed, allowing 2 opportunities to reject the null hypothesis of no group differences, only values of P < .01 were considered significant. RESULTS Chart Review Intervention During the 8-week period of chart review, 53 inpatient charts were reviewed. A total of 99 reviews were completed in total, with 41 queries sent to physicians (41%). All but 2 queries were sent via e-mail. Sixteen second-request queries were sent. Twenty queries (53%) were agreed on and documented in the record. A physician disagreed with 1 query, so no change in documentation was made, and 17 queries yielded no response (44.7%). SOI/ROM Values Over the 3 time periods, 1009 cases were analyzed: 329 patients during the preintervention period, 306 patients during the intervention period, and 374 patients during the post-intervention period. The simple mean values of SOI in the 3 time periods were as follows: 1.72 before intervention, 1.69 during intervention, and 1.82 after intervention (P = .09, χ2). Simple mean values of ROM in each time period were 1.40, 1.43, and 1.56 respectively (P = .02, χ2), with mortality rates of 6.38%, 3.59%, and 5.61% respectively (P = .27, χ2). Raw data results are summarized in Table 2.TABLE: 2. Summary of Raw DataaEffect of Age and Sex on SOI and ROM Mean patient age differed significantly between time periods: 48.3 years of age before intervention, 52.1 years of age during intervention, and 53.1 years of age after intervention (P = .001, Kruskal-Wallis). Accounting for differences in age did not affect SOI (P = .24), ROM (P = .48), and raw mortality (P = .06, Cochran-Mantel-Haenszel). Sex distributions were similar in each time period (P = .64, χ2). Effect of Diagnosis The distribution of diagnoses in each time period is shown in Table 3. Primary diagnosis did not differ significantly between the preintervention and intervention time periods (P = .13), even when adjusted for age and sex (P = .28, Cochran-Mantel-Haenszel). However, when the preintervention and intervention periods were combined and compared with the postintervention period, differences in diagnoses were noted (P < .001, Cochran-Mantel-Haenszel).TABLE: 3. Distributions of Diagnoses Between 3 Time PeriodsIn an effort to account for differences in diagnoses, a statistical compromise had to be achieved between not using primary diagnoses as a covariant and using them with a large number of categories. Therefore, 3 categories were established on the basis of the diagnosis frequency: cardiovascular disease (32 deaths), brain contusion (6 deaths), and other (15 deaths). After diagnosis differences (3 categories) were accounted for with logistic regression, no differences in mortality rate were found between the postintervention period and either the intervention (P = .08) or preintervention (P = .15) period. No significant differences between preintervention and postinterventional periods for SOI (P = .29) or ROM (P = .48) were present when differences in diagnoses were accounted for (cumulative logit model). DISCUSSION Overall, we expected SOI to be lower during the preintervention period and the ROM modified by SOI to be lower during the intervention and postintervention periods. However, despite interventions such as educational in-service, progress note template, and reminders about the possibility of addending progress notes, no differences in SOI or ROM were present during active intervention or in the period after intervention. The lack of impact of intervention on SOI and ROM was not affected by the differences in age or diagnoses present among the 3 time periods. Other studies have shown success with progress note templates. Grogan et al15 focused on improvements to physician documentation and evaluated the effectiveness in terms of ICD-9 coding, APR-DRG, DRG weight, and University Healthcare Consortium-predicted mortality. A progress note template included a section developed by coding specialists with 40 of the most common general surgery comorbidities and complications (in check-box format). A significant increase was found in total ICD-9 codes, template-specific ICD-9 codes, APR-DRG, DRG weight, and University Healthcare Consortium-predicted mortality. Sprtel and Zlabek16 also showed success with the implementation of a progress note template in conjunction with a brief documentation lecture. Their results showed an absolute increase in the highest code by 14.5%, increased billable income by $10 385, and improved resident awareness of documentation. A number of interventions for improvement in documentation and assessment end points have been suggested. Marco and Buchman17 noted that simply asking for private commitment to change can yield measurable results. They obtained in writing acknowledgement that improvement in documentation was necessary and noticed that the acknowledging physicians showed improvement in the percentage of cases with the required documentation over time. As-Sanie et al18 had success with obstetrics/gynecology residents after providing individual instructional sessions with faculty on coding and documentation, whereas Lemen19 also showed success within the same specialty with the assistance of an online module. At the other end of the spectrum, Tinsley20 described the use of a whole multidisciplinary team to improve documentation among psychiatry residents. The team met regularly to clarify resident charting responsibilities, to make the inpatient record a better communication tool, and to consider the various causes of charting deficiencies. Improvement in charting 4 of 5 items (admission note, an off-service note, descriptions of medication changes, daily progress notes, and the name and discipline of the individual recording these items) improved significantly after 1 month of intervention and was maintained at 6 months. Table 4 summarizes these intervention results.TABLE: 4. Summary of Literature ReviewaTime is likely necessary to establish educational interventions that generate long-lasting habits in physicians and improve documentation. Relationships are present between repetition and automaticity of such habits. For instance, in 1 study,33 82 mostly postgraduate students were asked to choose a healthy eating, drinking, or exercise behavior to convert into a daily habit. A self-report habit index34 was used to quantify habit strength. During 12 weeks of active study, 48% of participants reached levels thought to be consistent with habit formation. Further analysis concluded that the time needed for participants to reach 95% of their automaticity ranged from 18 to 254 days (mean, 64 days). The 8 weeks of active intervention in this study may not have been sufficient to allow documentation habits to form fully. Furthermore, educators must also question whether the amount of time required to learn simple habits differs from more complex habits requiring additional planning. Verplanken35 showed that when repetitions are limited, a simple behavior had a higher habit score than a complex behavior. Physician documentation in the setting of demanding schedules and the intricacies of medical coding likely falls into the category of a complex habit. Therefore, physicians' documentation habits promoting better documentation may be on the longer end of the to The effect the number of daily repetitions on the time to automaticity is also This study other that may improvement in documentation. did not to of queries with documentation The physicians would not be to their e-mail in the day or and progress note were not Additionally, physicians may have that an or new note in the medical record for the purpose of to a query was given their other A more of review and physician feedback have to an increase in in the medical record. and medical for diagnoses that were and not appropriately documented is a Over the 8 weeks of the intervention period, 99 reviews on 53 charts were Therefore, of the total neurosurgical admissions during the 8-week period, only of them were reviewed at during their For review and more nurse-reviewer might be required to review a of inpatient charts before significant results can be in improving documentation be that the progress note template was progress note was from Grogan et was modified by a multidisciplinary the of neurosurgical and the assistant manager of medical to include complications and comorbidities typical of neurosurgical patients.

A longitudinal study of emotional intelligence training for otolaryngology residents and faculty.
Importance: Emotions underlie and influence physician communications and relationships with patients and colleagues. Training programs to enhance emotional attunement, or emotional intelligence (EI), for physicians and assess training effects are scarce.
Objective: To assess whether an EI training program for otolaryngology residents and faculty affects patient satisfaction.
Design, setting, and participants: Prospective longitudinal, cohort study of physician residents and faculty in an EI training program at the Department of Otolaryngology, University of Kansas Medical Center, with annual training from 2005 to 2011.
Interventions: Three levels of interventions included 4 years of repeated EI assessment, 7 years of highly interactive EI training with high-risk/high-stress simulations, and ongoing modeling and mentoring of EI skills by faculty.
Main outcomes and measures: Four levels of outcome of the EI training were assessed with the following questions: Did participants enjoy the program? Could they apply the training to their practice? Did it change their behavior? Did it affect patient satisfaction? The Emotional Quotient Inventory (EQ-i) was administered to faculty and residents, and the Press Ganey Patient Satisfaction Survey was completed by patients.
Results: Ninety-seven percent of participants (103 of 106) reported that they enjoyed the programs, and 98% (104 of 106) reported that they have or could have applied what they learned. Participants demonstrated improvement in mean EQ-i scores from 102.19 (baseline/pretraining) to 107.29 (posttraining and assessment 1 year later; change, 6.71; 95% CI, 3.44-9.98). This increase was sustained in successive years, and these results were supported with linear growth curve analysis. The total department mean EQ-i score in pretraining year 2005 was 104.29 ("average" range), with posttraining scores in the "high average" range (112.46 in 2006, 111.67 in 2007, and 113.15 in 2008). An increase in EQ-i scores and EI training corresponded with an increase in patient satisfaction scores. Percentile rank patient satisfaction scores before EI training ranged from 85% to 90%; after training, scores ranged from 92% to 99%.
Conclusions and relevance: Emotional intelligence training positively influences patient satisfaction and may enhance medical education and health care outcome.
