The Incredible Years Parents and Babies Program: A Pilot Randomized Controlled Trial.

Introduction: Infancy is an important period of life; adverse experiences during this stage can have both immediate and lifelong impacts on the child's mental health and well-being. This study evaluates the effects of offering the Incredible Years Parents and Babies (IYPB) program as a universal intervention. Method: We conducted a pragmatic, two-arm, parallel pilot randomized controlled trial; 112 families with newborns were randomized to the IYPB program (76) or usual care (36) with a 2:1 allocation ratio. The primary outcome was parenting confidence at 20 weeks(Karitane Parenting Confidence Scale and Parental Stress Scale). Secondary outcomes include measures of parent health, parent-child relationship, infant development, parent-child activities, and network. Interviewers and data analysts were blind to allocation status. Multiple linear-regression analyses were used for evaluating the effects of the intervention. Results: There were no intervention effects on the primary outcomes. Only one effect was detected for secondary outcomes, intervention mothers reported a significantly smaller network than control mothers (β = -0.15 [-1.85,-0.28]). When examining the lowest-functioning mothers in moderator analyses, we found that intervention mothers reported significantly higher parent stress (β = 5.33 [0.27,10.38]), lower parenting confidence (β = -2.37 [-4.45,-0.29]), and worse mental health than control mothers (β = -18.62 [-32.40,-4.84]). In contrast, the highest functioning intervention mothers reported significantly lower parent stress post-intervention (β = -6.11 [-11.07,-1.14]). Conclusion: Overall, we found no effects of the IYPB as a universal intervention for parents with infants. The intervention was developed to be used with groups of low functioning families and may need to be adapted to be effective with universal parent groups. The differential outcomes for the lowest and highest functioning families suggest that future research should evaluate the effects of delivering the IYPB intervention to groups of parents who have similar experiences with parenting and mental health. Trial registration: ClinicalTrials.gov NCT01931917.

The EMPOWER blended digital intervention for relapse prevention in schizophrenia: a feasibility cluster randomised controlled trial in Scotland and Australia.

Background: Early warning signs monitoring by service users with schizophrenia has shown promise in preventing relapse but the quality of evidence is low. We aimed to establish the feasibility of undertaking a definitive randomised controlled trial to determine the effectiveness of a blended digital intervention for relapse prevention in schizophrenia. Methods: This multicentre, feasibility, cluster randomised controlled trial aimed to compare Early signs Monitoring to Prevent relapse in psychosis and prOmote Well-being, Engagement, and Recovery (EMPOWER) with treatment as usual in community mental health services (CMHS) in Glasgow and Melbourne. CMHS were the unit of randomisation, selected on the basis of those that probably had five or more care coordinators willing to participate. Participants were eligible if they were older than 16 years, had a schizophrenia or related diagnosis confirmed via case records, were able to provide informed consent, had contact with CMHS, and had had a relapse within the previous 2 years. Participants were randomised within stratified clusters to EMPOWER or to continue their usual approach to care. EMPOWER blended a smartphone for active monitoring of early warning signs with peer support to promote self-management and clinical triage to promote access to relapse prevention. Main outcomes were feasibility, acceptability, usability, and safety, which was assessed through face-to-face interviews. App usage was assessed via the smartphone and self-report. Primary end point was 12 months. Participants, research assistants and other team members involved in delivering the intervention were not masked to treatment conditions. Assessment of relapse was done by an independent adjudication panel masked to randomisation group. The study is registered at ISRCTN (99559262). Findings: We identified and randomised eight CMHS (six in Glasgow and two in Melbourne) comprising 47 care coordinators. We recruited 86 service users between Jan 19 and Aug 8, 2018; 73 were randomised (42 [58%] to EMPOWER and 31 [42%] to treatment as usual). There were 37 (51%) men and 36 (49%) women. At 12 months, main outcomes were collected for 32 (76%) of service users in the EMPOWER group and 30 (97%) of service users in the treatment as usual group. Of those randomised to EMPOWER, 30 (71%) met our a priori criterion of more than 33% adherence to daily monitoring that assumed feasibility. Median time to discontinuation of these participants was 31·5 weeks (SD 14·5). There were 29 adverse events in the EMPOWER group and 25 adverse events in the treatment as usual group. There were 13 app-related adverse events, affecting 11 people, one of which was serious. Fear of relapse was lower in the EMPOWER group than in the treatment as usual group at 12 months (mean difference -7·53 (95% CI -14·45 to 0·60; Cohen's d -0·53). Interpretation: A trial of digital technology to monitor early warning signs blended with peer support and clinical triage to detect and prevent relapse appears to be feasible, safe, and acceptable. A further main trial is merited. Funding: UK National Institute for Health Research Health Technology Assessment programme and the Australian National Health and Medical Research Council.

A randomized controlled trial of 'MUMentum Pregnancy': Internet-delivered cognitive behavioral therapy program for antenatal anxiety and depression.

Background: Anxiety and depression are common during pregnancy and associated with adverse outcomes for the mother and infant if left untreated. Despite the need to improve treatment accessibility and uptake in this population, no studies have investigated internet-delivered cognitive behavioural therapy (iCBT) for antenatal anxiety and depression. In a randomised controlled trial, we examined the efficacy and acceptability of a brief, unguided iCBT intervention - the MUMentum Pregnancy program - in pregnant women with anxiety and/or depression. Methods: Participants meeting clinical threshold on validated self-report measures of generalised anxiety and/or depression were recruited online and randomised to iCBT (n = 43) or a treatment as usual (TAU) control (n = 44). Outcomes were assessed at baseline, post-treatment and four-week follow-up; and included anxiety, depression, psychological distress, antenatal bonding, quality of life, and treatment acceptability. Results: Of the 36 women who started iCBT, 26 completed all three lessons of treatment (76% adherence rate). iCBT produced moderate to large effect size reductions for anxiety on the GAD-7 (Hedges' g = 0.76) and psychological distress on the Kessler-10 (g = 0.88) that were superior to TAU. Only small nonsignificant differences were found for depression outcomes (g = < 0.35). Participants reported that iCBT was an acceptable treatment for antenatal anxiety and/or depression. Limitations: Lack of an active control condition and long-term postpartum follow-up. Conclusions: This is the first study to evaluate brief unguided iCBT for antenatal anxiety and depression. While our findings are promising, particularly for anxiety reduction, additional RCTs are required to establish treatment efficacy.

The Association of Grit With Burnout Components (Professional Efficacy, Exhaustion, and Cynicism) Among Academic Rheumatologists: The TRUMP 2 -SLE Study.

Objectives: There is a high prevalence of burnout among rheumatologists. Grit, which is defined as possessing perseverance and a passion to achieve long-term goals, is predictive of success in many professions; however, whether grit is associated with burnout remains unclear, especially among academic rheumatologists, who have multiple simultaneous responsibilities. Thus, the purpose of this study was to examine the associations between grit and self-reported burnout components-professional efficacy, exhaustion, and cynicism-in academic rheumatologists. Methods: This cross-sectional study involved 51 rheumatologists from 5 university hospitals. The exposure was grit, measured using mean scores for the 8-item Short Grit Scale (range, 1-5 [5 = extremely high grit]). The outcome measures were mean scores for 3 burnout domains (exhaustion, professional efficacy, and cynicism; range, 1-6; measured using the 16-item Maslach Burnout Inventory-General Survey). General linear models were fitted with covariates (age, sex, job title [assistant professor or higher vs lower], marital status, and having children). Results: Overall, 51 physicians (median age, 45 years; interquartile range, 36-57; 76% men) were included. Burnout positivity was found in 68.6% of participants (n = 35/51; 95% confidence interval [CI], 54.1, 80.9). Higher grit was associated with higher professional efficacy (per 1-point increase; 0.51 point; 95% CI, 0.18, 0.84) but not with exhaustion or cynicism. Being male and having children were associated with lower exhaustion (-0.69; 95% CI, -1.28, -0.10; p = 0.02; and -0.85; 95% CI, -1.46, -0.24; p = 0.006). Lower job title (fellow or part-time lecturer) was associated with higher cynicism (0.90; 95% CI, 0.04, 1.75; p = 0.04). Conclusions: Grit is associated with higher professional efficacy among academic rheumatologists. To prevent burnout among staff, supervisors who manage academic rheumatologists should assess their staff's individual grit.

The relevance of cognitive emotion regulation to psychotic symptoms - A systematic review and meta-analysis.

Numerous studies emphasise the pivotal role of negative affect in the formation and maintenance of positive symptoms, which moves emotion regulation (ER) as a contributing factor into focus. We systematically reviewed and meta-analysed case-control studies reporting cross-sectional, correlative and experimental data of ER strategies in patients with psychotic disorders. In total, 42 studies were eligible, providing data for 2498 subjects and 3381 healthy controls. Questionnaire-based cross-sectional data (k=39) indicated strongest effects for rumination (g=-0,67 [-0,85 to -0,48]), self-blaming (g=-0,56; [-0,76 to -0,37]) and distraction (g=0,55 [0,11 to 0,98]). Suppression was more frequently (g=-0,36 [-0,56 to -0,16]) and cognitive reappraisal less frequently used (g=0,41 [0,28 to 0,55]), but heterogeneity was high. Correlative data (k=6) supported the assumption of an association between maladaptive strategies and positive symptoms (r=0,34 [0,22 to 0,44]). Less evidence of group differences was found in the experimental studies (k=3). The findings support the notion that ER is markedly impaired in patients with psychotic disorders. However, future research will need to further clarify the extent to which difficulties continue to exist after controlling for context and emotion intensity. The large effects for rumination and self-blaming point to promising treatment targets but also raise questions concerning the specifity of findings.

Effects of Balance Training on Balance Performance in Healthy Older Adults: A Systematic Review and Meta-analysis.

Background: The effects of balance training (BT) in older adults on proxies of postural control and mobility are well documented in the literature. However, evidence-based dose-response relationships in BT modalities (i.e., training period, training frequency, training volume) have not yet been established in healthy older adults. Objectives: The objectives of this systematic literature review and meta-analysis are to quantify BT intervention effects and to additionally characterize dose-response relationships of BT modalities (e.g., training period, training frequency) through the analysis of randomized controlled trials (RCTs) that could maximize improvements in balance performance in healthy community-dwelling older adults. Data sources: A computerized systematic literature search was performed in the electronic databases PubMed and Web of Science from January 1985 up to January 2015 to capture all articles related to BT in healthy old community-dwelling adults. Study eligibility criteria: A systematic approach was used to evaluate the 345 articles identified for initial review. Only RCTs were included if they investigated BT in healthy community-dwelling adults aged ≥65 years and tested at least one behavioral balance performance outcome (e.g., center of pressure displacements during single-leg stance). In total, 23 studies met the inclusionary criteria for review. Study appraisal and synthesis methods: Weighted mean standardized mean differences between subjects (SMDbs) of the intervention-induced adaptations in balance performance were calculated using a random-effects model and tested for an overall intervention effect relative to passive controls. The included studies were coded for the following criteria: training modalities (i.e., training period, training frequency, training volume) and balance outcomes [static/dynamic steady-state (i.e., maintaining a steady position during standing and walking), proactive balance (i.e., anticipation of a predicted perturbation), reactive balance (i.e., compensation of an unpredicted perturbation) as well as balance test batteries (i.e., combined testing of different balance components as for example the Berg Balance Scale)]. Heterogeneity between studies was assessed using I2 and Chi2-statistics. The methodological quality of each study was tested by means of the Physiotherapy Evidence Database (PEDro) Scale. Results: Weighted mean SMDbs showed that BT is an effective means to improve static steady-state (mean SMDbs = 0.51), dynamic steady-state (mean SMDbs = 0.44), proactive (mean SMDbs = 1.73), and reactive balance (mean SMDbs = 1.01) as well as the performance in balance test batteries (mean SMDbs = 1.52) in healthy older adults. Our analyses regarding dose-response relationships in BT revealed that a training period of 11-12 weeks (mean SMDbs= 1.26), a frequency of three training sessions per week (mean SMDbs= 1.20), a total number of 36-40 training sessions (mean SMDbs = 1.39), a duration of a single training session of 31-45 min (mean SMDbs = 1.19), and a total duration of 91-120 min of BT per week (mean SMDbs = 1.93) of the applied training modalities is most effective in improving overall balance performance. However, it has to be noted that effect sizes for the respective training modalities were computed independently (i.e., modality specific). Because of the small number of studies that reported detailed information on training volume (i.e., number of exercises per training session, number of sets and/or repetitions per exercise, duration of single-balance exercises) dose-response relationships were not computed for these parameters. Limitations: The present findings have to be interpreted with caution because we indirectly compared dose-response relationships across studies using SMDbs and not in a single controlled study as it is difficult to separate the impact of a single training modality (e.g., training frequency) from that of the others. Moreover, the quality of the included studies was rather limited with a mean PEDro score of 5 and the heterogeneity between studies was considerable (i.e., I2 = 76-92 %). Conclusions: Our detailed analyses revealed that BT is an effective means to improve proxies of static/dynamic steady-state, proactive, and reactive balance as well as performance in balance test batteries in healthy older adults. Furthermore, we were able to establish effective BT modalities to improve balance performance in healthy older adults. Thus, practitioners and therapists are advised to consult the identified dose-response relationships of this systematic literature review and meta-analysis. However, further research of high methodologic quality is needed to determine (1) dose-response relationships of BT in terms of detailed information on training volume (e.g., number of exercises per training session) and (2) a feasible and effective method to regulate training intensity in BT.

Psychiatric and neuropsychiatric presentations associated with severe coronavirus infections: a systematic review and meta-analysis with comparison to the COVID-19 pandemic.

Background: Before the COVID-19 pandemic, coronaviruses caused two noteworthy outbreaks: severe acute respiratory syndrome (SARS), starting in 2002, and Middle East respiratory syndrome (MERS), starting in 2012. We aimed to assess the psychiatric and neuropsychiatric presentations of SARS, MERS, and COVID-19. Methods: In this systematic review and meta-analysis, MEDLINE, Embase, PsycINFO, and the Cumulative Index to Nursing and Allied Health Literature databases (from their inception until March 18, 2020), and medRxiv, bioRxiv, and PsyArXiv (between Jan 1, 2020, and April 10, 2020) were searched by two independent researchers for all English-language studies or preprints reporting data on the psychiatric and neuropsychiatric presentations of individuals with suspected or laboratory-confirmed coronavirus infection (SARS coronavirus, MERS coronavirus, or SARS coronavirus 2). We excluded studies limited to neurological complications without specified neuropsychiatric presentations and those investigating the indirect effects of coronavirus infections on the mental health of people who are not infected, such as those mediated through physical distancing measures such as self-isolation or quarantine. Outcomes were psychiatric signs or symptoms; symptom severity; diagnoses based on ICD-10, DSM-IV, or the Chinese Classification of Mental Disorders (third edition) or psychometric scales; quality of life; and employment. Both the systematic review and the meta-analysis stratified outcomes across illness stages (acute vs post-illness) for SARS and MERS. We used a random-effects model for the meta-analysis, and the meta-analytical effect size was prevalence for relevant outcomes, I2 statistics, and assessment of study quality. Findings: 1963 studies and 87 preprints were identified by the systematic search, of which 65 peer-reviewed studies and seven preprints met inclusion criteria. The number of coronavirus cases of the included studies was 3559, ranging from 1 to 997, and the mean age of participants in studies ranged from 12·2 years (SD 4·1) to 68·0 years (single case report). Studies were from China, Hong Kong, South Korea, Canada, Saudi Arabia, France, Japan, Singapore, the UK, and the USA. Follow-up time for the post-illness studies varied between 60 days and 12 years. The systematic review revealed that during the acute illness, common symptoms among patients admitted to hospital for SARS or MERS included confusion (36 [27·9%; 95% CI 20·5-36·0] of 129 patients), depressed mood (42 [32·6%; 24·7-40·9] of 129), anxiety (46 [35·7%; 27·6-44·2] of 129), impaired memory (44 [34·1%; 26·2-42·5] of 129), and insomnia (54 [41·9%; 22·5-50·5] of 129). Steroid-induced mania and psychosis were reported in 13 (0·7%) of 1744 patients with SARS in the acute stage in one study. In the post-illness stage, depressed mood (35 [10·5%; 95% CI 7·5-14·1] of 332 patients), insomnia (34 [12·1%; 8·6-16·3] of 280), anxiety (21 [12·3%; 7·7-17·7] of 171), irritability (28 [12·8%; 8·7-17·6] of 218), memory impairment (44 [18·9%; 14·1-24·2] of 233), fatigue (61 [19·3%; 15·1-23·9] of 316), and in one study traumatic memories (55 [30·4%; 23·9-37·3] of 181) and sleep disorder (14 [100·0%; 88·0-100·0] of 14) were frequently reported. The meta-analysis indicated that in the post-illness stage the point prevalence of post-traumatic stress disorder was 32·2% (95% CI 23·7-42·0; 121 of 402 cases from four studies), that of depression was 14·9% (12·1-18·2; 77 of 517 cases from five studies), and that of anxiety disorders was 14·8% (11·1-19·4; 42 of 284 cases from three studies). 446 (76·9%; 95% CI 68·1-84·6) of 580 patients from six studies had returned to work at a mean follow-up time of 35·3 months (SD 40·1). When data for patients with COVID-19 were examined (including preprint data), there was evidence for delirium (confusion in 26 [65%] of 40 intensive care unit patients and agitation in 40 [69%] of 58 intensive care unit patients in one study, and altered consciousness in 17 [21%] of 82 patients who subsequently died in another study). At discharge, 15 (33%) of 45 patients with COVID-19 who were assessed had a dysexecutive syndrome in one study. At the time of writing, there were two reports of hypoxic encephalopathy and one report of encephalitis. 68 (94%) of the 72 studies were of either low or medium quality. Interpretation: If infection with SARS-CoV-2 follows a similar course to that with SARS-CoV or MERS-CoV, most patients should recover without experiencing mental illness. SARS-CoV-2 might cause delirium in a significant proportion of patients in the acute stage. Clinicians should be aware of the possibility of depression, anxiety, fatigue, post-traumatic stress disorder, and rarer neuropsychiatric syndromes in the longer term.

A co-designed mHealth programme to support healthy lifestyles in Māori and Pasifika peoples in New Zealand (OL@-OR@): a cluster-randomised controlled trial.

Background: The OL@-OR@ mobile health programme was co-designed with Māori and Pasifika communities in New Zealand, to support healthy lifestyle behaviours. We aimed to determine whether use of the programme improved adherence to health-related guidelines among Māori and Pasifika communities in New Zealand compared with a control group on a waiting list for the programme. Methods: The OL@-OR@ trial was a 12-week, two-arm, cluster-randomised controlled trial. A cluster was defined as any distinct location or setting in New Zealand where people with shared interests or contexts congregated, such as churches, sports clubs, and community groups. Members of a cluster were eligible to participate if they were aged 18 years or older, had regular access to a mobile device or computer, and had regular internet access. Clusters of Māori and of Pasifika (separately) were randomly assigned (1:1) to either the intervention or control condition. The intervention group received the OL@-OR@ mHealth programme (smartphone app and website). The control group received a control version of the app that only collected baseline and outcome data. The primary outcome was self-reported adherence to health-related guidelines, which were measured with a composite health behaviour score (of physical activity, smoking, alcohol intake, and fruit and vegetable intake) at 12 weeks. The secondary outcomes were self-reported adherence to health-related behaviour guidelines at 4 weeks; self-reported bodyweight at 12 weeks; and holistic health and wellbeing status at 12 weeks, in all enrolled individuals in eligible clusters; and user engagement with the app, in individuals allocated to the intervention. Adverse events were not collected. This study is registered with the Australian New Zealand Clinical Trials Registry, ACTRN12617001484336. Findings: Between Jan 24 and Aug 14, 2018, we enrolled 337 Māori participants from 19 clusters and 389 Pasifika participants from 18 clusters (n=726 participants) in the intervention group and 320 Māori participants from 15 clusters and 405 Pasifika participants from 17 clusters (n=725 participants) in the control group. Of these participants, 227 (67%) Māori participants and 347 (89%) Pasifika participants (n=574 participants) in the intervention group and 281 (88%) Māori participants and 369 (91%) Pasifika participants (n=650 participants) in the control group completed the 12-week follow-up and were included in the final analysis. Relative to baseline, adherence to health-related behaviour guidelines increased at 12 weeks in both groups (315 [43%] of 726 participants at baseline to 329 [57%] of 574 participants in the intervention group; 331 [46%] of 725 participants to 369 [57%] of 650 participants in the control group); however, there was no significant difference between intervention and control groups in adherence at 12 weeks (odds ratio [OR] 1·13; 95% CI 0·84-1·52; p=0·42). Furthermore, the proportion of participants adhering to guidelines on physical activity (351 [61%] of 574 intervention group participants vs 407 [63%] of 650 control group participants; OR 1·03, 95% CI 0·73-1·45; p=0·88), smoking (434 [76%] participants vs 501 [77%] participants; 1·12, 0·67-1·87; p=0·66), alcohol consumption (518 [90%] participants vs 596 [92%] participants; 0·73, 0·37-1·44; p=0·36), and fruit and vegetable intake (194 [34%] participants vs 196 [30%] participants; 1·08, 0·79-1·49; p=0·64) did not differ between groups. We found no significant differences between the intervention and control groups in any secondary outcome. 147 (26%) intervention group participants engaged with the OL@-OR@ programme (ie, set at least one behaviour change goal online). Interpretation: The OL@-OR@ mobile health programme did not improve adherence to health-related behaviour guidelines amongst Māori and Pasifika individuals.

Parent Training for Preschool ADHD in Routine, Specialist Care: A Randomized Controlled Trial.

Objective: Parent training is recommended for attention-deficit/hyperactivity disorder (ADHD) in preschool children. Evidence-based interventions are important, but only if they produce better outcomes than usual care. Method: The authors conducted a multicenter, 2-arm, parallel-group, randomized controlled trial in routine specialist ADHD clinics in the Danish Child and Adolescent Mental Health Services. Children (N = 164, 3-7 years old) with ADHD received a well-established parent training program (New Forest Parenting Programme; n = 88) or treatment as usual (n = 76). The primary outcome was parent ratings of child ADHD symptoms. Secondary outcomes included teacher ratings and direct observations of ADHD symptoms. Outcomes were measured at baseline, after treatment, and at follow-up (36 weeks later). Representativeness of participants was evaluated against the total national cohort of children (N = 1,378, 3-7 years old) diagnosed with ADHD during the same period using the Danish Civil Registration System. Statistical analysis used a repeated measure model. Results: After treatment, the parent training program was superior to treatment as usual on parent-rated ADHD symptoms (p = .009; effect size d = 0.30) and on parenting self-efficacy and family strain. Effects persisted to 36 weeks after treatment. There were no effects on teacher ratings or direct observations of ADHD or on ratings of conduct problems or parenting. The clinical sample was similar to the national cohort of young children with ADHD. Conclusion: Evidence-based parent training has value as an intervention for preschool ADHD in routine clinical settings. As in previous trials, effects were restricted to parent-reported outcomes. Surprisingly, there were no effects on child conduct problems.

An online breathing and wellbeing programme (ENO Breathe) for people with persistent symptoms following COVID-19: a parallel-group, single-blind, randomised controlled trial.

Background: There are few evidence-based interventions for long COVID; however, holistic approaches supporting recovery are advocated. We assessed whether an online breathing and wellbeing programme improves health related quality-of-life (HRQoL) in people with persisting breathlessness following COVID-19. Methods: We conducted a parallel-group, single-blind, randomised controlled trial in patients who had been referred from one of 51 UK-based collaborating long COVID clinics. Eligible participants were aged 18 years or older; were recovering from COVID-19 with ongoing breathlessness, with or without anxiety, at least 4 weeks after symptom onset; had internet access with an appropriate device; and were deemed clinically suitable for participation by one of the collaborating COVID-19 clinics. Following clinical assessment, potential participants were given a unique online portal code. Participants were randomly assigned (1:1) to either immediate participation in the English National Opera (ENO) Breathe programme or to usual care. Randomisation was done by the research team using computer-generated block randomisation lists, with block size 10. The researcher responsible for randomisation was masked to responses. Participants in the ENO Breathe group participated in a 6-week online breathing and wellbeing programme, developed for people with long COVID experiencing breathlessness, focusing on breathing retraining using singing techniques. Those in the deferred group received usual care until they exited the trial. The primary outcome, assessed in the intention-to-treat population, was change in HRQoL, assessed using the RAND 36-item short form survey instrument mental health composite (MHC) and physical health composite (PHC) scores. Secondary outcome measures were the chronic obstructive pulmonary disease assessment test score, visual analogue scales (VAS) for breathlessness, and scores on the dyspnoea-12, the generalised anxiety disorder 7-item scale, and the short form-6D. A thematic analysis exploring participant experience was also conducted using qualitative data from focus groups, survey responses, and email correspondence. This trial is registered with ClinicalTrials.gov, NCT04830033. Findings: Between April 22 and May 25, 2021, 158 participants were recruited and randomly assigned. Of these, eight (5%) individuals were excluded and 150 participants were allocated to a treatment group (74 in the ENO Breathe group and 76 in the usual care group). Compared with usual care, ENO Breathe was associated with an improvement in MHC score (regression coefficient 2·42 [95% CI 0·03 to 4·80]; p=0·047), but not PHC score (0·60 [-1·33 to 2·52]; p=0·54). VAS for breathlessness (running) favoured ENO Breathe participation (-10·48 [-17·23 to -3·73]; p=0·0026). No other statistically significant between-group differences in secondary outcomes were observed. One minor self-limiting adverse event was reported by a participant in the ENO Breathe group who felt dizzy using a computer for extended periods. Thematic analysis of ENO Breathe participant experience identified three key themes: (1) improvements in symptoms; (2) feeling that the programme was complementary to standard care; and (3) the particular suitability of singing and music to address their needs. Interpretation: Our findings suggest that an online breathing and wellbeing programme can improve the mental component of HRQoL and elements of breathlessness in people with persisting symptoms after COVID-19. Mind-body and music-based approaches, including practical, enjoyable, symptom-management techniques might have a role supporting recovery. Funding: Imperial College London.

Antiretrovirals for reducing the risk of mother-to-child transmission of HIV infection.

Background: Antiretroviral drugs reduce viral replication and can reduce mother-to-child transmission of HIV either by lowering plasma viral load in pregnant women or through post-exposure prophylaxis in their newborns. In rich countries, highly active antiretroviral therapy (HAART) which usually comprises three drugs, has reduced the mother-to-child transmission rates to around 1-2%, but HAART is not always available in low- and middle-income countries. In these countries, various simpler and less costly antiretroviral regimens have been offered to pregnant women or to their newborn babies, or to both. Objectives: To determine whether, and to what extent, antiretroviral regimens aimed at decreasing the risk of mother-to-child transmission of HIV infection achieve a clinically useful decrease in transmission risk, and what effect these interventions have on maternal and infant mortality and morbidity. Search strategy: We sought to identify all relevant studies regardless of language or publication status by searching the Cochrane HIV/AIDS Review Group Trials Register, The Cochrane Library, MEDLINE, EMBASE and AIDSearch and relevant conference abstracts. We also contacted research organizations and experts in the field for unpublished and ongoing studies. The original review search strategy was conducted in 2002 and updated in 2006 and again in 2009. Selection criteria: Randomised controlled trials of any antiretroviral regimen aimed at decreasing the risk of mother-to-child transmission of HIV infection compared with placebo or no treatment, or compared with another antiretroviral regimen. Data collection and analysis: Two authors independently selected relevant studies, extracted data and assessed trial quality. For the primary outcomes, we used survival analysis to estimate the probability of infants being infected with HIV (the observed proportion) at various specific time-points and calculated efficacy at a specific time as the relative reduction in the proportion infected. Efficacy, at a specific time, is defined as the preventive fraction in the exposed group compared to the reference group, which is the relative reduction in the proportion infected: 1-(Re/Rf). For those studies where efficacy and hence confidence intervals were not calculated, we calculated the approximate confidence intervals for the efficacy using recommended methods. For analysis of results that are not based on survival analyses we present the relative risk for each trial outcome based on the number randomised. No meta-analysis was conducted as no trial assessed identical drug regimens. Main results: Twenty-five trials including 18,901 participants with a median trial sample size of 627 ranging from 50 to 1,844 participants were included in this update. Twenty-two trials randomised mothers (18 pre-natally and four in labour) and followed up their infants, and three trials randomised infants. The first trial began in April 1991 and assessed zidovudine (ZDV) versus placebo and since then, the type, dosage and duration of drugs to be compared has been modified in each subsequent trial. We present the results stratified by regimen and type of feeding. Antiretrovirals versus placebo In breastfeeding populations, three trials found that:ZDV given to mothers from 36 to 38 weeks gestation, during labour and for 7 days after delivery significantly reduced HIV infection at 4-8 weeks (Efficacy 32.00%; 95% CI 1.50 to 62.50), 3 to 4 months (Efficacy 33.07%; 95% CI 5.57 to 60.57), 6 months (Efficacy 34.55%; 95% CI 9.05 to 60.05), 12 months (Efficacy 34.31%; 95% CI 9.30 to 59.32) and 18 months (Efficacy 29.74%; 95% CI 2.73 to 56.75).ZDV given to mothers from 36 weeks gestation and during labour significantly reduced HIV infection at 4 to 8 weeks (Efficacy 43.78%; 95% CI 8.78 to 78.78) and 3 to 4 months (Efficacy 36.95%; 95% CI 2.94 to 70.96) but not at birth.ZDV plus lamivudine (3TC) given to mothers from 36 weeks gestation, during labour and for 7 days after delivery and to babies for the first 7 days after birth (PETRA 'regimen A') significantly reduced HIV infection (Efficacy 62.75%; 95% CI 40.76 to 84.74) and a combined endpoint of HIV infection or death (Efficacy 62.75 [, ]61.00%; 95% CI 40.76 to 84.74) at 4 to 8 weeks but these effects were not sustained at 18 months.ZDV plus 3TC given to mothers from the start of labour until 7 days after delivery and to babies for the first 7 days after birth (PETRA 'regimen B') significantly reduced HIV infection (Efficacy 41.83%; 95% CI 12.82 to 70.84) and HIV infection or death at 4 to 8 weeks (Efficacy 35.91%; 95% CI 8.41 to 63.41) but the effects were not sustained at 18 months.ZDV plus 3TC given to mothers during labour only (PETRA 'regimen C') with no treatment to babies did not reduce the risk of HIV infection at either 4 to 8 weeks or 18 months. In non-breastfeeding populations, three trials found that:ZDV given to mothers from 14 to 34 weeks gestation and during labour and to babies for the first 6 weeks after birth significantly reduced HIV infection in babies at 18 months (Efficacy 66.22%; 95% CI 33.94 to 98.50).ZDV given to mothers from 36 weeks gestation and during labour with no treatment to babies ('Thai-CDC regimen') significantly reduced HIV infection at 4 to 8 weeks (Efficacy 50.26%; 95% CI 13.80 to 86.72) but not at birthZDV given to mothers from 38 weeks gestation and during labour with no treatment to babies did not influence HIV transmission at 6 months. Longer versus shorter regimens using the same antiretrovirals One trial in a breastfeeding population found that:ZDV given to mothers during labour and to their babies for the first 3 days after birth compared with ZDV given to mothers from 36 weeks and during labour (similar to 'Thai-CDC') resulted in HIV infection rates that were not significantly different at birth, 4-8 weeks, 3 to 4 months, 6 months and 12 months. Three trials in non-breastfeeding populations found that:ZDV given to mothers from 28 weeks gestation during labour and to infants for the first 3 days after birth compared with ZDV given to mothers from 35 weeks gestation through labour and to infants from birth to 6 weeks significantly reduced HIV infection rate at 6 months (Efficacy 45.35 %; 95% CI 1.39 to 89.31) but compared with the same regimen ZDV given to mothers from 28 weeks gestation through labour and to infants from birth to 6 weeks did not result in a statistically significant difference in HIV infection at 6 months. ZDV given to mothers from 35 weeks gestation during labour and to infants for the first 3 days after birth was considered ineffective for reducing transmission rates and this regimen was discontinued. An antenatal/intrapartum course of ZDV used for a median of 76 days compared with an antenatal/intrapartum ZDV regimen used for a median 28 days with no treatment to babies in either group did not result in HIV infection rates that were significantly different at birth and at 3 to 4 months. In a programme where mothers were routinely receiving ZDV in the third trimester of pregnancy and babies were receiving one week of ZDV therapy, a single dose of nevirapine (NVP) given to mothers in labour and to their babies soon after birth compared with a single dose of NVP given to mothers only resulted in HIV infection rates that were not significantly different at birth and 6 months. However the reduction in risk of HIV infection or death at 6 months was marginally significant (Efficacy 45.00%; 95% CI -4.00 to 94.00).Antiretroviral regimens using different drugs and durations of treatmentIn breastfeeding populations, three trials found that:A single dose of NVP given to mothers at the onset of labour plus a single dose of NVP given to their babies immediately after birth ('HIVNET 012 regimen') compared with ZDV given to mothers during labour and to their babies for a week after birth resulted in lower HIV infection rates at 4-8 weeks (Efficacy 41.00%; 95% CI 11.84 to 70.16), 3-4 months (Efficacy 38.91%; 95% CI 11.24 to 66.58), 12 months (Efficacy 35.98 [9.25, 62.71]36.00%; 95% CI 8.56 to 63.44) and 18 months (Efficacy 39.15%; 95% CI 13.81 to 64.49). In addition, the NVP regimen significantly reduced the risk of HIV infection or death at 4-8 weeks (Efficacy 41.74%; 95% CI 14.30 to 69.18), 3 to 4 months (Efficacy 40.00%; 95% CI 14.34 to 65.66), 12 months (Efficacy 32.17%; 95% CI 8.51 to 55.83) and 18 months (Efficacy 32.57 [9.93, 55.21]33.00%; 95% CI 9.93 to 55.21).The 'HIVNET 012 regimen' plus ZDV given to babies for 1 week after birth compared with the 'HIVNET 012 regimen' alone did not result in a statistically significant difference in HIV infection at 4 to 8 weeks.A single dose of NVP given to babies immediately after birth plus ZDV given to babies for 1 week after birth compared with a single dose of NVP given to babies only significantly reduced the HIV infection rate at 4 to 8 weeks (Efficacy 36.79%; 95% CI 3.57 to 70.01).Five trials in non-breastfeeding populations found that:In a population in which mothers were receiving 'standard' antiretroviral for HIV infection a single dose of NVP given to mothers in labour plus a single dose of NVP given to babies immediately after birth ('HIVNET 012 regimen') compared with placebo did not result in a statistically significant difference in HIV infection rates at birth and at 4 to 8 weeks. The 'Thai CDC regimen' compared with the 'HIVNET 012 regimen' did not result in a significant difference in HIV infection at 4 to 8 weeks.A single dose of NVP given to babies immediately after birth compared to ZDV given to babies for the first 6 weeks after birth did not result in a significant difference in HIV infection rates at 4-8 weeks and 3 to 4 months.

Geriatric assessment-identified deficits in older cancer patients with normal performance status.

Background: We investigated whether a brief geriatric assessment (GA) would identify important patient deficits that could affect treatment tolerance and care outcomes within a sample of older cancer patients rated as functionally normal (80%-100%) on the Karnofsky performance status (KPS) scale. Methods: Cancer patients aged ≥65 years were assessed using a brief GA that included both professionally and patient-scored KPS and measures of comorbidity, polypharmacy, cognition, function, nutrition, and psychosocial status. Data were analyzed using descriptive statistics and multivariable logistic regression. Results: The sample included 984 patients: mean age was 73 years (range: 65-99 years), 74% were female, and 89% were white. GA was conducted before (23%), during (41%), or after (36%) treatment. Overall, 54% had a breast cancer diagnosis (n = 528), and 46% (n = 456) had cancers at other sites. Moreover, 81% of participants (n = 796) had both professionally and self-rated KPS ≥80, defined as functionally normal, and those patients are the focus of analysis. In this subsample, 550 (69%) had at least 1 GA-identified deficit, 222 (28%) had 1 deficit, 140 (18%) had 2 deficits, and 188 (24%) had ≥3 deficits. Specifically, 43% reported taking ≥9 medications daily, 28% had decreased social activity, 25% had ≥4 comorbidities, 23% had ≥1 impairment in instrumental activities of daily living, 18% had a Timed Up and Go time ≥14 seconds, 18% had ≥5% unintentional weight loss, and 12% had a Mental Health Index score ≤76. Conclusion: Within this sample of older cancer patients who were rated as functionally normal by KPS, GA identified important deficits that could affect treatment tolerance and outcomes.

Randomized, double-blind, placebo-controlled study of postoperative nightly sildenafil citrate for the prevention of erectile dysfunction after bilateral nerve-sparing radical prostatectomy.

Four weeks after bilateral nerve-sparing radical retropubic prostatectomy, men with normal erectile function before surgery were randomized to double-blind sildenafil (50 or 100 mg) or placebo nightly for 36 weeks, followed by an 8-week drug-free period before assessment of erectile function. Enrollment was prematurely ceased and only 76 men completed because, assuming a placebo response rate similar to the published literature (for example, 34% in meta-analysis), the 25% response at blinded interim review suggested a lack of treatment effect. On the contrary, spontaneous erectile function (a combined score of >or=8 for questions 3 and 4 of the International Index of Erectile Function and a positive response to 'Were erections good enough for satisfactory sexual activity?') occurred in only 4% of the placebo group (n=1 of 25) versus 27% (n=14 of 51, P=0.0156, Fisher's exact test) of the sildenafil group. Nightly sildenafil administration for 36 weeks after surgery markedly increased the return of normal spontaneous erections.

Percutaneous mitral valve repair for mitral regurgitation in high-risk patients: results of the EVEREST II study.

Background: The EVEREST II (Endovascular Valve Edge-to-Edge REpair STudy) High-Risk registry and REALISM Continued Access Study High-Risk Arm are prospective registries of patients who received the MitraClip device (Abbott Vascular, Santa Clara, California) for mitral regurgitation (MR) in the United States. Objectives: The purpose of this study was to report 12-month outcomes in high-risk patients treated with the percutaneous mitral valve edge-to-edge repair. Methods: Patients with grades 3 to 4+ MR and a surgical mortality risk of ≥12%, based on the Society of Thoracic Surgeons risk calculator or the estimate of a surgeon coinvestigator following pre-specified protocol criteria, were enrolled. Results: In the studies, 327 of 351 patients completed 12 months of follow-up. Patients were elderly (76 ± 11 years of age), with 70% having functional MR and 60% having prior cardiac surgery. The mitral valve device reduced MR to ≤2+ in 86% of patients at discharge (n = 325; p < 0.0001). Major adverse events at 30 days included death in 4.8%, myocardial infarction in 1.1%, and stroke in 2.6%. At 12 months, MR was ≤2+ in 84% of patients (n = 225; p < 0.0001). From baseline to 12 months, left ventricular (LV) end-diastolic volume improved from 161 ± 56 ml to 143 ± 53 ml (n = 203; p < 0.0001) and LV end-systolic volume improved from 87 ± 47 ml to 79 ± 44 ml (n = 202; p < 0.0001). New York Heart Association functional class improved from 82% in class III/IV at baseline to 83% in class I/II at 12 months (n = 234; p < 0.0001). The 36-item Short Form Health Survey physical and mental quality-of-life scores improved from baseline to 12 months (n = 191; p < 0.0001). Annual hospitalization rate for heart failure fell from 0.79% pre-procedure to 0.41% post-procedure (n = 338; p < 0.0001). Kaplan-Meier survival estimate at 12 months was 77.2%. Conclusions: The percutaneous mitral valve device significantly reduced MR, improved clinical symptoms, and decreased LV dimensions at 12 months in this high-surgical-risk cohort.

Effectiveness of a Novel Integrative Online Treatment for Depression (Deprexis): Randomized Controlled Trial

BACKGROUND: Depression is associated with immense suffering and costs, and many patients receive inadequate care, often because of the limited availability of treatment. Web-based treatments may play an increasingly important role in closing this gap between demand and supply. We developed the integrative, Web-based program Deprexis, which covers therapeutic approaches such as behavioral activation, cognitive restructuring, mindfulness/acceptance exercises, and social skills training. OBJECTIVE: To evaluate the effectiveness of the Web-based intervention in a randomized controlled trial. METHODS: There were 396 adults recruited via Internet depression forums in Germany, and they were randomly assigned in an 80:20 weighted randomization sequence to either 9 weeks of immediate-program-access as an add-on to treatment-as-usual (N = 320), or to a 9-week delayed-access plus treatment-as-usual condition (N = 76). At pre- and post-treatment and 6-month follow-up, we measured depression (Beck Depression Inventory) as the primary outcome measure and social functioning (Work and Social Adjustment Scale) as the secondary outcome measure. Complete analyses and intention-to-treat analyses were performed. RESULTS: Of 396 participants, 216 (55%) completed the post-measurement 9 weeks later. Available case analyses revealed a significant reduction in depression severity (BDI), Cohen's d = .64 (CI 95% = 0.33 - 0.94), and significant improvement in social functioning (WSA), Cohen's d = .64, 95% (CI 95% = 0.33 - 0.95). These improvements were maintained at 6-month follow-up. Intention-to-treat analyses confirmed significant effects on depression and social functioning improvements (BDI: Cohen's d = .30, CI 95% = 0.05 - 0.55; WSA: Cohen's d = .36, CI 95% = 0.10 - 0.61). Moreover, a much higher percentage of patients in the intervention group experienced a significant reduction of depression symptoms (BDI: odds ratio [OR] = 6.8, CI 95% = 2.90 - 18.19) and recovered more often (OR = 17.3, 95% CI 2.3 - 130). More than 80% of the users felt subjectively that the program had been helpful. CONCLUSIONS: This integrative, Web-based intervention was effective in reducing symptoms of depression and in improving social functioning. Findings suggest that the program could serve as an adjunctive or stand-alone treatment tool for patients suffering from symptoms of depression.

Case-mix, care pathways, and outcomes in patients with traumatic brain injury in CENTER-TBI: a European prospective, multicentre, longitudinal, cohort study.

Background: The burden of traumatic brain injury (TBI) poses a large public health and societal problem, but the characteristics of patients and their care pathways in Europe are poorly understood. We aimed to characterise patient case-mix, care pathways, and outcomes of TBI. Methods: CENTER-TBI is a Europe-based, observational cohort study, consisting of a core study and a registry. Inclusion criteria for the core study were a clinical diagnosis of TBI, presentation fewer than 24 h after injury, and an indication for CT. Patients were differentiated by care pathway and assigned to the emergency room (ER) stratum (patients who were discharged from an emergency room), admission stratum (patients who were admitted to a hospital ward), or intensive care unit (ICU) stratum (patients who were admitted to the ICU). Neuroimages and biospecimens were stored in repositories and outcome was assessed at 6 months after injury. We used the IMPACT core model for estimating the expected mortality and proportion with unfavourable Glasgow Outcome Scale Extended (GOSE) outcomes in patients with moderate or severe TBI (Glasgow Coma Scale [GCS] score ≤12). The core study was registered with ClinicalTrials.gov, number NCT02210221, and with Resource Identification Portal (RRID: SCR_015582). Findings: Data from 4509 patients from 18 countries, collected between Dec 9, 2014, and Dec 17, 2017, were analysed in the core study and from 22 782 patients in the registry. In the core study, 848 (19%) patients were in the ER stratum, 1523 (34%) in the admission stratum, and 2138 (47%) in the ICU stratum. In the ICU stratum, 720 (36%) patients had mild TBI (GCS score 13-15). Compared with the core cohort, the registry had a higher proportion of patients in the ER (9839 [43%]) and admission (8571 [38%]) strata, with more than 95% of patients classified as having mild TBI. Patients in the core study were older than those in previous studies (median age 50 years [IQR 30-66], 1254 [28%] aged >65 years), 462 (11%) had serious comorbidities, 772 (18%) were taking anticoagulant or antiplatelet medication, and alcohol was contributory in 1054 (25%) TBIs. MRI and blood biomarker measurement enhanced characterisation of injury severity and type. Substantial inter-country differences existed in care pathways and practice. Incomplete recovery at 6 months (GOSE <8) was found in 207 (30%) patients in the ER stratum, 665 (53%) in the admission stratum, and 1547 (84%) in the ICU stratum. Among patients with moderate-to-severe TBI in the ICU stratum, 623 (55%) patients had unfavourable outcome at 6 months (GOSE <5), similar to the proportion predicted by the IMPACT prognostic model (observed to expected ratio 1·06 [95% CI 0·97-1·14]), but mortality was lower than expected (0·70 [0·62-0·76]). Interpretation: Patients with TBI who presented to European centres in the core study were older than were those in previous observational studies and often had comorbidities. Overall, most patients presented with mild TBI. The incomplete recovery of many patients should motivate precision medicine research and the identification of best practices to improve these outcomes.

The adult respiratory distress syndrome cognitive outcomes study: long-term neuropsychological function in survivors of acute lung injury.

Rationale: Cognitive and psychiatric morbidity is common and potentially modifiable after acute lung injury (ALI). However, practical measures of neuropsychological function for use in multicenter trials are lacking. Objectives: To determine whether a validated telephone-based neuropsychological test battery is feasible in a multicenter trial. To determine the frequency and risk factors for long-term neuropsychological impairment. Methods: As an adjunct study to the Acute Respiratory Distress Syndrome Clinical Trials Network Fluid and Catheter Treatment Trial, we assessed neuropsychological function at 2 and 12 months post-hospital discharge. Measurements and main results: Of 406 eligible survivors, we approached 261 to participate and 213 consented. We tested 122 subjects at least once, including 102 subjects at 12 months. Memory, verbal fluency, and executive function were impaired in 13% (12 of 92), 16% (15 of 96), and 49% (37 of 76) of long-term survivors. Long-term cognitive impairment was present in 41 of the 75 (55%) survivors who completed cognitive testing. Depression, post-traumatic stress disorder, or anxiety was present in 36% (37 of 102), 39% (40 of 102), and 62% (63 of 102) of long-term survivors. Enrollment in a conservative fluid-management strategy (P = 0.005) was associated with cognitive impairment and lower partial pressure of arterial oxygen during the trial was associated with cognitive (P = 0.02) and psychiatric impairment (P = 0.02). Conclusions: Neuropsychological function can be assessed by telephone in a multicenter trial. Long-term neuropsychological impairment is common in survivors of ALI. Hypoxemia is a risk factor for long-term neuropsychological impairment. Fluid management strategy is a potential risk factor for long-term cognitive impairment; however, given the select population studied and an unclear mechanism, this finding requires confirmation.

The influence of Chinese culture on family caregivers of stroke survivors: A qualitative study.

Aims and objectives: To explore and describe the caregiving experiences of Chinese stroke caregivers. Background: Previous research has indicated that culture can have a significant impact on the stroke caregiving experience. Moreover, scant research exists on stroke caregivers' experience within the Chinese culture. Design: A qualitative descriptive design was used. Methods: In-depth, semistructured interviews were conducted with 25 family caregivers of stroke survivors. The interviews were audiotaped, transcribed and analysed. Content analysis was also performed. Findings: Twenty-five family caregivers of stroke survivors were recruited for the study. On average, respondents were 66 years old (range 45-82 years). Of 25 interviewees, 76% were female, 64% were spouse-caregivers and 36% were children-caregivers. Three themes reflecting the influence of Chinese culture on stroke caregiving emerged from the interviews. (i) Caregiving role perception. Informants accepted caregiving for the sick family member as an expected part of life, a culturally prescribed obligation and an expression of reciprocal love. (ii) Coping strategies. Connecting with family resources and connecting with inner strength were frequently reported coping strategies. (iii) Self-sacrifice. Informants identified self-reliance and feeling of restraint in their utilisation or access of formal caregiving service. Chinese caregivers sacrifice themselves for the care recipients regardless of the hardships and the neglect of their own health. Conclusion: Our findings provide a comprehensive and culturally sensitive perspective in understanding the experience of stroke caregivers in Chinese communities. Cultural and religious backgrounds were found to influence Chinese stroke caregivers' experience, coping strategies and self-sacrifice behaviour in idiosyncratic ways. Relevance to clinical practice: Research on the practice of culture can serve as a basis for the formulation of specific policies and effective interventions for supporting stroke caregivers of different cultural backgrounds.

Traditional expectations versus US realities: first- and second-generation Asian Indian perspectives on end-of-life care.

Background: Although end-of-life care preferences vary across racial/ethnic groups, little is known about how cultural values affect end-of-life care preferences among South Asian immigrants and their offspring in the US. Objective: To examine the perspectives of first- and second-generation South Asians living in the US regarding end-of-life care. Design: Focus group study. Discussions explored participant preferences and experiences with family members facing the end of life. Participants: Twelve first-generation and 11 second-generation self-identified Asian Indians living in the mid-Atlantic region. Approach: Content analysis of focus group transcripts. Results: First-generation participants ranged in age from 41 to 76 years and were evenly split by gender. Second-generation participants ranged in age from 23 to 36 years and included seven women and four men. All participants were highly educated, and two thirds were either studying or working in a health care field. All but two subjects were Hindu. Several themes emerged that highlighted cultural differences and challenges for this population in the context of end-of-life care: attitudes toward death and suffering; family duty; and preferences for information disclosure and decision making. Participants described cultural challenges due to the evolution of traditional roles, lack of explicit discussion between patients and family members about preferences and care expectations, and a tension between wanting to meet traditional expectations and the challenges in doing so given US social realities. Conclusions: Traditional cultural values, such as duty to family, greatly influenced end-of-life care preferences and retained importance across generations. Clinicians caring for Asian Indian patients at the end of life may be better able to assess care preferences after exploring the complex interplay between traditional expectations and specific social realities for each patient. Particular attention should be given to attitudes toward death and suffering, family duty, and preferences for information disclosure and decision making.

Heterogeneity of phenotypes in severe asthmatics. The Belgian Severe Asthma Registry (BSAR).

Unlabelled: The Belgian severe asthma registry is a web-based registry encompassing demographic, clinical, functional and inflammatory data of severe asthmatics (SA), aiming at improving awareness, knowledge on its natural history and subphenotypes, and offering tools to optimize care of this asthma population. Methods: The cross-sectional analyses of this registry included 350 SA as defined by the ATS (2000) from 9 Belgian centres, with at least one year follow up. Results: Mean age was 55 ± 14 yrs. SA were more frequently female (57%) and atopic (70%). Late-onset asthma (≥40 yr) was observed in 31% of SA. Current smokers represented 12% while 31% were ex-smokers. In addition to high doses ICS + LABA, 65% of patients were receiving LTRA, 27% anti-IgE and 24% maintenance oral corticosteroids (8 mg (Interquartile range-IQR:4-8) methylprednisolone). Despite impaired airflow (median FEV1:67%; IQR: 52-81) only 65% had a post-bronchodilator FEV1/FVC ratio <70%. The median blood eosinophil count was 240/mm³. The median FENO was 26 ppb (IQR: 15-43) and 22% of SA had FENO ≥ 50 ppb. Induced sputum was successful in 86 patients. Eosinophilic asthma (sputum Eos ≥ 3%) was the predominant phenotype (55%) while neutrophilic (sputum Neu ≥ 76%) and paucigranulocytic asthma accounted for 22% and 17% respectively. Comorbidities included rhinitis and chronic rhinosinusitis (49%), nasal polyposis (19%), oesophageal reflux (36%), overweight and obesity (47%) and depression (19%). In addition, 8% had aspirin-induced asthma and 3% ABPA. Asthma was not well-controlled in 83% according to ACT < 20 and 77% with ACQ > 1.5. Conclusion: In this cohort of patients with severe asthma, the majority displayed indices of persistent airflow limitation and eosinophilic inflammation despite high-dose corticosteroids, suggesting potential for eosinophil-targeted biotherapies.

Emergency IVF for embryo freezing to preserve female fertility: a French multicentre cohort study.

Study question: What are the outcomes of French emergency IVF procedures involving embryo freezing for fertility preservation before gonadotoxic treatment? Summary answer: Pregnancy rates after emergency IVF, cryopreservation of embryos, storage, thawing and embryo transfer (embryo transfer), in the specific context of the preservation of female fertility, seem to be similar to those reported for infertile couples undergoing ART. Study design, size, duration: A French retrospective multicentre cohort study initiated by the GRECOT network-the French Study Group for Ovarian and Testicular Cryopreservation. We sent an e-mail survey to the 97 French centres performing the assisted reproduction technique in 2011, asking whether the centre performed emergency IVF and requesting information about the patients' characteristics, indications, IVF cycles and laboratory and follow-up data. The response rate was 53.6% (52/97). Participants/materials, setting, methods: Fourteen French centres reported that they performed emergency IVF (56 cycles in total) before gonadotoxic treatment, between 1999 and July 2011, in 52 patients. Main results and the role of chance: The patients had a mean age of 28.9 ± 4.3 years, and a median length of relationship of 3 years (1 month-15 years). Emergency IVF was indicated for haematological cancer (42%), brain tumour (23%), sarcoma (3.8%), mesothelioma (n = 1) and bowel cancer (n = 1). Gynaecological problems accounted for 17% of indications. In 7.7% of cases, emergency IVF was performed for autoimmune diseases. Among the 52 patients concerned, 28% (n = 14) had undergone previous courses of chemotherapy before beginning controlled ovarian stimulation (COS). The initiation of gonadotoxic treatment had to be delayed in 34% of the patients (n = 19). In total, 56 cycles were initiated. The mean duration of stimulation was 11.2 ± 2.5 days, with a mean peak estradiol concentration on the day on which ovulation was triggered of 1640 ± 1028 pg/ml. Three cycles were cancelled due to ovarian hyperstimulation syndrome (n = 1), poor response (n = 1) and treatment error (n = 1). A mean of 8.2 ± 4.8 oocytes were retrieved, with 6.1 ± 4.2 mature oocytes and 4.4 ± 3.3 pronuclear-stage embryos per cycle. The mean number of embryos frozen per cycle was 4.2 ± 3.1. During follow-up, three patients died from the consequences of their disease. For the 49 surviving patients, 22.5% of the couples concerned (n = 11) requested embryo replacement. A total of 33 embryos were thawed with a post-thawing survival rate of 76%. Embryo replacement was finally performed for 10 couples with a total of 25 embryos transferred, leading to one biochemical pregnancy, one miscarriage and three live births. Clinical pregnancy rate and live birth per couple who wanted a pregnancy after cancer were, respectively, 36% (95% CI = 10.9-69.2%) and 27% (95% CI = 6.0-61%). Limitations, reasons for caution: The overall response rate for clinics was 53.6%. Therefore, it is not only that patients may not have been included, but also that those that were included were biased towards the University sector with a response rate of 83% (25/30) for a small number of patients. Wider implications of the findings: According to literature, malignant disease is a risk factor for a poor response to COS. However, patients having emergency IVF before gonadotoxic treatment have a reasonable chance of pregnancy after embryo replacement. Embryo freezing is a valuable approach that should be included among the strategies used to preserve fertility. Study funding/competing interest(s): No external funding was sought for this study. None of the authors has any conflict of interest to declare.

Heart rate variability

IN FOCUSHeart rate variabilityHarald M. StaussHarald M.

Indeed, the periodic beat of the heart was used to define the speed of music. In music notation, the traditional Italian term "moderato" originally referred to one beat of the measure per walking pace (76-80 paces/min) or heartbeat (∼72 beats/min). The use of the heartbeat to define the speed of music may imply that the periodicity of the beat of the heart is very constant. However, this is not necessarily the case. In fact, loss of heart rate variability can indicate severe cardiovascular diseases and reliably predict poor outcome of such conditions (18, 22, 27, 47a). This In Focus article reviews sources of heart rate variability, its role as a prognostic marker for cardiovascular diseases, and its application in estimation of cardiac autonomic nervous system activity. All of these topics have been addressed intensely in articles published in the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology during the last two years. In healthy subjects, the sinoatrial node located at the posterior wall of the right atrium initiates each beat of the heart. Due to the unstable membrane potential of the myocytes located in this region, action potentials are generated periodically at a fairly constant frequency. This relatively constant frequency generated by the autorhythmicity of the sinoatrial node is modulated by many factors that add variability to the heart rate signal at different frequencies. According to the Task Force of The European Society of Cardiology and The North American Society of Pacing and Electrophysiology (47a) these frequencies are classified into 1) ultra-low frequencies (ULF; >5-h cycle length) that include the circadian rhythm (6, 9, 34, 54); 2) very low frequencies (VLF; >25-s cycle length) that are supposed to be affected by temperature regulation (1, 7, 34, 52, 54) and humoral systems (9, 36); 3) low frequencies (LF; >6-s cycle length in humans) that are sensitive to changes in cardiac sympathetic (and presumably parasympathetic) nerve activity (27, 30); and 4) high frequencies (HF; 2.5- to 6.0-s cycle length in humans) that are synchronized to the respiratory rhythm (5) and are primarily modulated by cardiac parasympathetic innervation (38).The most prominent oscillation in the ULF band of the heart rate spectrum is the circadian rhythm. The autonomic nervous system contributes significantly to circadian heart rate variability. Using long-term recordings in conscious rabbits, Barrett et al. (6) demonstrated a strong circadian rhythm in heart rate, mean arterial blood pressure, renal blood flow, and renal sympathetic nerve activity. The importance of this study is that it clearly demonstrates that sympathetic nerve discharges exhibit a strong circadian rhythmicity. The paraventricular nucleus of the hypothalamus (PVN) appears to play a central role in mediating the circadian rhythm of autonomic nervous system activity. First, GABAergic and glutamatergic neurons project from the suprachiasmatic nuclei of the hypothalamus (SCN) to spinal-projecting neurons of the PVN (12). The SCN is the major central oscillator that triggers the day/night cycle. It receives photic input from the retina (47) and drives many neuroendocrine, metabolic, autonomic, and behavioral circadian rhythms (14, 16, 21, 31, 35, 44, 46, 50). In addition, microinjections of the inhibitory neurotransmitter GABA into the PVN of anesthetized rats elicit dose-dependent decreases in renal sympathetic nerve activity, whereas bicuculline (a GABA antagonist) increases renal sympathetic nerve activity (56). Second, from the PVN, neurons project to the nucleus of the solitary tract (that integrates inputs from the baroreceptors), the nucleus ambiguus (origin of preganglionic parasympathetic neurons to the heart), the rostroventrolateral medulla (location of sympathetic premotor neurons), and the intermediolateral cell column of the thoracolumbar spinal cord (location of preganglionic sympathetic neurons). Thus PVN neurons can modulate autonomic nervous system activity by sending inputs to major sites of autonomic nervous system regulation. As an example, a pivotal role of the PVN for sympathoexcitation during parturition was recently demonstrated in sheep. The increase in sympathetic nerve activity that accompanies birth in maternal animals was prevented by stereotactic lesioning of the PVN (43). Taken together, a major component of the circadian heart rate variability is elicited by diurnal fluctuations in autonomic nervous system activity, generated by corresponding fluctuations of neuronal activity within the PVN, which depend on circadian inputs originating from the SCN.It has been suggested that thermoregulation affects VLF heart rate variability (10, 26). Cooling the heart causes bradycardia, a mechanism used in heart surgeries. Conversely, fever is known to increase heart rate. Raising body core temperature from 36.0 to 36.6°C caused an increase in heart rate by almost 40 beats/min in male subjects (1), whereas acutely reducing ambient temperature from thermoneutral conditions (35°C) to 29, 23, and 17°C, reduced heart rate from 400 to 250 beats/min in 8-day-old rats (7). In addition, lowering temperature in the isolated working rat heart from 37 to 31°C reduced heart rate from 332 to 215 beats/min and markedly increased heart rate variability (28), indicating that parts of the temperature effects on heart rate and heart rate variability are independent from the autonomic nervous system. In contrast to the tachycardia that accompanies acute elevations in temperature, chronically raising ambient temperature in adult rodents from a standard housing temperature of 21-23°C to thermoneutral conditions (29-30°C) reduced heart rate by roughly 50 beats/min in rats (34) and by 200-300 beats/min in mice (54). The authors of these articles (34, 54) suggested that standard housing temperatures are associated with cold stress that causes parallel activation of brown adipose tissue, cardiac, and vasomotor sympathetic drives that elicits nonshivering thermogenesis and tonically elevates heart rate and arterial blood pressure. These and other studies indicate that both direct effects of temperature on pacemaker activity of the sinus node (28) and indirect effects mediated via the autonomic nervous system (11, 25, 51, 55) mediate temperature effects on heart rate and heart rate variability. Thus fluctuation in temperature is an important source of heart rate variability that should not be underestimated. In a more recent study, this was taken into account by core body temperature correction of heart rate variability (3).Endocrine factors affecting heart rate variability include thyroxine, reproductive hormones, the renin-angiotensin system, steroids, and others. Chronic subcutaneous infusion of angiotensin II in rats markedly increased blood pressure and heart rate variability, expressed as standard deviation (9). In contrast, chronic corticosterone treatment is likely to reduce baroreflex-mediated heart rate variability, because baroreceptor-heart rate (39) and baroreceptor-renal sympathetic nerve activity reflex sensitivity (41) were blunted in chronically corticosterone-treated rats. Furthermore, an interaction between angiotensin II and glucocorticoids was recently described. Intracerebro-ventricular microinjections of angiotensin II AT1 receptor antagonists caused marked decreases in mean blood pressure and heart rate in rats chronically treated with corticosterone but not in control animals (40). This interaction is likely to take place in the central nervous system, because peripheral angiotensin II AT1 receptor blockade did not alter the effects of betamethasone treatment on blood pressure, heart rate, and baroreceptor-heart rate reflex sensitivity in newborn lambs (42).Adenosine is a substance less known to affect heart rate variability. It is produced locally in the heart (53) and binds to A1-adenosinergic receptors, which are among the earliest expressed G protein-coupled receptors in the heart (36). The A1-adenosinergic agonist N6-cyclopentyladenosine dose dependently reduced heart rate in murine embryos, whereas 1,3-dipropyl-8-cyclopentylxanthine, an A1-adenosinergic antagonist, increased heart rate (36). Adenosine also exerts central nervous system effects in various brain areas (15, 20). Microinjections of adenosine into the nucleus of the solitary tract of awake rats caused dose-dependent changes in heart rate: low doses (0.01 nmol) produced a bradycardic response, whereas high doses (2.5-5.0 nmol) elicited a tachycardic response (15). Thus adenosine may indeed be involved in the regulation of heart rate and modulate heart rate variability via local cardiac and central nervous system effects. It has been proposed that the intrinsic cardiac nervous system plays an active role in regulating cardiac function (4, 37, 45, 57). This nervous system consists of sympathetic and parasympathetic neurons and interconnecting local circuits (37). Neurons in the canine right atrial ganglionated plexus (RAGP) spontaneously generate activity even after chronic cardiac autonomic denervation (45). Right atrial neurons in patients undergoing coronary artery bypass surgery generated spontaneous activity that was unrelated to the cardiac cycle but sensitive to changes in systemic arterial pressure, indicating that these neurons receive pressure-sensitive sensory inputs (4). In addition, it has been suggested that substance P acts as a neuromodulator and neurotransmitter in intracardiac ganglia of the guinea pig, modulates the response to vagal inputs, and triggers action potentials at the site of parasympathetic ganglia independent of acetylcholine (57). Furthermore, the right atrial (RAGP) and the posterior atrial ganglionated plexus (PAGP) appear to have different functions. Ablation of the PAGP reduced vagally mediated bradycardia by 26%, whereas RAGP ablation completely abolished this response. Inhibition of sympathetically mediated tachycardia by vagal stimulation was attenuated by ablation of either plexus (37). Thus parasympathetic efferent neurons are primarily located in the RAGP, whereas prejunctional parasympathetic-sympathetic interactions also involve neurons within the PAGP (37). The spontaneous activity of neurons in the intrinsic cardiac nervous system, even after cardiac denervation (45), suggests an active role of this system in regulating heart rate. However, the impact of the intrinsic cardiac nervous system on heart rate variability remains to be elucidated. The importance of the autonomic nervous system for heart rate variability in humans becomes apparent in patients following cardiac transplantation, in whom heart rate variability is markedly reduced (49). Although reinnervation is possible after months and years, initially transplanted hearts can be considered to be denervated. Thus the reduced heart rate variability in cardiac transplanted patients (49) underlines the importance of an intact autonomic innervation for spontaneously occurring heart rate variability. A major component of the chronotropic effect of the autonomic nervous system is linked to cAMP. Intracellular cAMP increases the inward current of Na+ (funny current, If), which determines the rate of the slow diastolic depolarization that precedes each action potential. The activity of adenylate cyclase and thus intracellular cAMP levels are increased by stimulation of sympathetic β1-adrenergic receptors and decreased (via a Gi protein) by stimulation of parasympathetic muscarinic receptors. Thus cardiac sympathetic innervation increases the rate of the slow diastolic depolarization and accelerates heart rate, while cardiac parasympathetic innervation elicits opposite effects. Interestingly, parasympathetic-mediated changes in heart rate occur much faster than sympathetic-mediated effects on heart rate (27, 30, 47a). As a result, cardiac sympathetic nervous system activity can only affect LF components of heart rate variability, whereas the parasympathetic nervous system can also modulate HF components. A hitherto unsolved question in this context is if the rapid heart rate response to parasympathetic stimulation compared with the slow effect of sympathetic inputs is due to 1) different kinetics of β1-adrenergic vs. muscarinic receptors, 2) different kinetics of adenylate cyclase vs. phosphodiesterase, the enzyme that cleaves cAMP, or 3) fast parasympathetic-mediated opening of KACh channels (via muscarinic receptors and a GK protein). Support for the latter possibility comes from experiments in the rabbit sinoatrial node that demonstrated that activation of KACh channels contributes to the initial slowing of heart rate as a result of vagal stimulation (8).On the basis of the different frequency response characteristics of sympathetic and parasympathetic modulation of heart rate, frequency analysis of heart rate variability is often used as a tool to determine "autonomic balance" or sympathetic and parasympathetic nervous system activity (27, 47a). As an example, the wavelet transform was recently used to determine cardiac autonomic responses to reperfusion in patients with thrombolysis after coronary thrombosis. Depending on the location of the infarct, marked alterations in LF or HF spectral power of heart rate or in the LF/HF ratio was observed in all successful reperfusions (48).The HF component corresponds to the frequency of respiration and is driven by the vagus as indicated by the strong respiratory pattern of cardiac vagal motoneurons in the nucleus ambiguus (38). The LF component has been ascribed to sympathetic modulation of cardiac pacemaker activity, because a variety of studies demonstrated that acute interventions that increase sympathetic nervous system activity, such as orthostatic perturbations (17, 19, 33), mental stress (32), or handgrip exercise (13, 24) increases LF spectral power of heart rate (27, 30). In addition to acute perturbations of cardiac sympathetic nerve activity, feedback oscillations generated by the baroreceptor reflex also appear to contribute to LF spectral power of heart rate as it was demonstrated that sinoaortic denervation markedly reduces the LF component (27, 30). Despite the strong modulation of heart rate by the autonomic nervous system, the LF and HF spectral components of heart rate variability may not always be very reliable markers for cardiac sympathetic and parasympathetic "tone" (30). In a recent study, muscle sympathetic nerve activity was recorded together with heart rate variability during application of lower body negative pressure that is known to increase muscle sympathetic nerve activity (17, 33). At higher levels of lower body negative pressure (-15 mmHg), both muscle sympathetic nerve activity and relative LF spectral power of heart rate increased significantly, whereas HF spectral power decreased (17). These findings suggest that LF spectral power reflects cardiac sympathetic "tone." However, no correlation within subjects was found between changes in LF/HF ratio and muscle sympathetic nerve activity (17). Thus heart rate variability does not reliably reflect the sympathetic response to orthostatic stress. Respiration-related fluctuation of heart rate (respiratory sinus arrhythmia) is probably the most often investigated component of heart rate variability, as it is believed that this component reflects respiration-driven vagal modulation of sinus arrhythmia (27). In a recent study, Rentero et al. (38) recorded the electrical activity from cardiac vagal motoneurons in the nucleus ambiguus. Firing of these neurons was modulated by the central respiratory cycle. This and other studies support the view that respiratory sinus arrhythmia is generated by central coupling of the respiratory oscillator with autonomic centers in the brain stem. However, a mechanical cardiopulmonary coupling as a source of respiration-related heart rate variability has also been suggested (5). The Bainbridge reflex causes a tachycardia in response to hypervolemia. This reflex is initiated by atrial mechanoreceptors and uses efferent sympathetic and parasympathetic pathways to modulate heart rate in response to changes in central venous pressure (23). Thus respiratory changes in central blood volume cause corresponding respiratory fluctuations in cardiac autonomic nervous system activity via the Bainbridge reflex. Only the parasympathetic component of the efferent pathway of the reflex can contribute to respiratory sinus arrhythmia, because sympathetic actions on heart rate are too damped to follow the respiratory frequency. The gain and phase of the transfer function between respiratory changes in lung volume and R-R intervals of the ECG were calculated in human subjects during graded changes in central blood volume (5). At the respiratory frequency, the phase was -180 degree, indicating that an inspiratory increase in central blood volume was associated with a decrease in R-R interval (increase in heart rate). Furthermore, the gain of the transfer function at the respiratory frequency steadily increased with increasing central volumes (except at the highest volume). Both of these findings confirm the presence of the Bainbridge reflex in humans (5). Thus, in addition to the central coupling of respiratory oscillators with cardiovascular centers, the Bainbridge reflex may contribute to respiration-related heart rate variability by mechanical cardiopulmonary coupling. There is general agreement that low heart rate variability is an unfavorable prognostic marker for cardiovascular diseases, such as diabetic autonomic neuropathy, hypertension, myocardial infarction, and heart failure (18, 22, 27, 29, 47a). Heart rate variability (variance of R-R intervals) was reduced in patients with mild hypertension (29) compared with normal values (1,134 ± 202 vs. 3,466 ± 1,018 ms2) provided by the Task Force (47a). In the rat model of myocardial infarction-induced congestive heart failure, Francis and colleagues (18) reported loss of spontaneous heart rate variability 6 wk after coronary artery ligation. Interestingly, reduced heart rate variability was also observed in a rat model of depression that is based on chronic (4 wk) mild stress application (22). Because depression is an independent risk factor for coronary artery disease, this finding may realistically model a human disease process. The reduction in heart rate variability was abolished by β-adrenergic receptor blockade, indicating that the reduced heart rate variability in this model of depression is related to elevated cardiac sympathetic tone (22).In summary, heart rate variability is generated by multiple factors not exclusively limited to the autonomic nervous system. Specific frequency components of heart rate variability mirror acute perturbations of the autonomic nervous system but do not always reflect autonomic nervous system activity. Simple statistics of heart rate variability, such as the standard deviation of R-R intervals in the ECG, can reliably predict the prognosis of cardiovascular diseases.I thank Dr. R.

Antiretrovirals for reducing the risk of mother-to-child transmission of HIV infection.

Background: Antiretroviral drugs (ARV) reduce viral replication and can reduce mother-to-child transmission of HIV either by lowing plasma viral load in pregnant women or through post-exposure prophylaxis in their newborns. In rich countries, highly active antiretroviral therapy (HAART) has reduced the vertical transmission rates to around 1-2%, but HAART is not yet widely available in low and middle income countries. In these countries, various simpler and less costly antiretroviral regimens have been offered to pregnant women or to their newborn babies, or to both. Objectives: To determine whether, and to what extent, antiretroviral regimens aimed at decreasing the risk of mother-to-child transmission of HIV infection achieve a clinically useful decrease in transmission risk, and what effect these interventions have on maternal and infant mortality and morbidity. Search strategy: We sought to identify all relevant studies regardless of language or publication status by searching the Cochrane HIV/AIDS Review Group Trials Register, The Cochrane Library, Medline, EMBASE and AIDSearch and relevant conference abstracts. We also contacted research organizations and experts in the field for unpublished and ongoing studies. The original review search strategy was updated in 2006. Selection criteria: Randomised controlled trials of any antiretroviral regimen aimed at decreasing the risk of mother-to-child transmission of HIV infection compared with placebo or no treatment. Data collection and analysis: Two authors independently selected relevant studies, extracted data and assessed trial quality. For the primary outcomes, we used survival analysis to estimate the probability of infants being infected with HIV (the observed proportion) at various specific time-points and calculated efficacy at a specific time as the relative reduction in the proportion infected. Efficacy, at a specific time, is defined as the preventive fraction in the exposed group compared to the reference group, which is the relative reduction in the proportion infected: 1-(Re/Rf). For those studies where efficacy and hence confidence intervals were not calculated, we calculated the approximate confidence intervals for the efficacy using recommended methods. For analysis of results that are not based on survival analyses we present the relative risk for each trial outcome based on the number randomised. No meta-analysis was conducted as no trial assessed the identical drug regimens. Main results: Eighteen trials including 14,398 participants conducted in 16 countries were eligible for inclusion in the review. The first trial began in April 1991 and assessed zidovudine (ZDV) versus placebo and since then, the type, dosage and duration of drugs to be compared has been modified in each subsequent trial. Antiretrovirals versus placebo In breastfeeding populations, three trials found that:ZDV given to mothers from 36 to 38 weeks gestation, during labour and for 7 days after delivery significantly reduced HIV infection at 4-8 weeks (Efficacy 32.00%; 95% CI 0.64 to 63.36), 3 to 4 months (Efficacy 34.00%; 95% CI 6.56 to 61.44), 6 months (Efficacy 35.00%; 95% CI 9.52 to 60.48), 12 months (Efficacy 34.00%; 95% CI 8.52 to 59.48) and 18 months (Efficacy 30.00%; 95% CI 2.56 to 57.44).ZDV given to mothers from 36 weeks gestation and during labour significantly reduced HIV infection at 4 to 8 weeks (Efficacy 44.00%; 95% CI 8.72 to 79.28) and 3 to 4 months (Efficacy 37.00%; 95% CI 3.68 to 70.32) but not at birth.ZDV plus lamivudine (3TC) given to mothers from 36 weeks gestation, during labour and for 7 days after delivery and to babies for the first 7 days of life (PETRA 'regimen A') significantly reduced HIV infection (Efficacy 63.00%; 95% CI 41.44 to 84.56) and a combined endpoint of HIV infection or death (Efficacy 61.00%; 95% CI 41.40 to 80.60) at 4 to 8 weeks but these effects were not sustained at 18 months.ZDV plus 3TC given to mothers from the start of labour until 7 days after delivery and to babies for the first 7 days of life (PETRA 'regimen B') significantly reduced HIV infection (Efficacy 42.00%; 95% CI 12.60 to 71.40) and HIV infection or death at 4 to 8 weeks (Efficacy 36.00%; 95% CI 8.56 to 63.44) but the effects were not sustained at 18 months.ZDV plus 3TC given to mothers during labour only (PETRA 'regimen C') with no treatment to babies did not reduce the risk of HIV infection at either 4 to 8 weeks or 18 months. In non-breastfeeding populations, three trials found that:ZDV given to mothers from 14 to 34 weeks gestation and during labour and to babies for the first 6 weeks of life significantly reduced HIV infection in babies at 18 months (Efficacy 66.00%; 95% CI 34.64 to 97.36).ZDV given to mothers from 36 weeks gestation and during labour with no treatment to babies ('Thai-CDC regimen') significantly reduced HIV infection at 4 to 8 weeks (Efficacy 50.00%; 95% CI 12.76 to 87.24) but not at birthZDV given to mothers from 38 weeks gestation and during labour with no treatment to babies did not influence HIV transmission at 6 months. Longer versus shorter regimens using the same antiretrovirals One trial in a breastfeeding population found that:ZDV given to mothers during labour and to their babies for the first 3 days of life compared with ZDV given to mothers from 36 weeks and during labour (similar to 'Thai-CDC') resulted in HIV infection rates that were not significantly different at birth, 4-8 weeks, 3 to 4 months, 6 months and 12 months. Three trials in non-breastfeeding populations found that:ZDV given to mothers from 28 weeks gestation during labour and to infants for the first 3 days after birth compared with ZDV given to mothers from 35 weeks gestation through labour and to infants from birth to 6 weeks significantly reduced HIV infection rate at 6 months (Efficacy 45.00%; 95% CI 1.88 to 88.12) but compared with the same regimen ZDV given to mothers from 28 weeks gestation through labour and to infants from birth to 6 weeks did not result in a statistically significant difference in HIV infection at 6 months. ZDV given to mothers from 35 weeks gestation during labour and to infants for the first 3 days after birth was considered ineffective for reducing transmission rates and this regimen was discontinued. An antenatal/intrapartum course of ZDV used for a median of 76 days compared with an antenatal/intrapartum ZDV regimen used for a median 28 days with no treatment to babies in either group did not result in HIV infection rates that were significantly different at birth and at 3 to 4 months. In a programme where mothers were routinely receiving ZDV in the third trimester of pregnancy and babies were receiving one week of ZDV therapy, a single dose of nevirapine (NVP) given to mothers in labour and to their babies soon after birth compared with a single dose of NVP given to mothers only resulted in HIV infection rates that were not significantly different at birth and 6 months. However the reduction in risk of HIV infection or death at 6 months was marginally significant (Efficacy 45.00%; 95% CI -4.00 to 94.00). Antiretroviral regimens using different drugs and durations of treatment In breastfeeding populations, three trials found that:A single dose of NVP given to mothers at the onset of labour plus a single dose of NVP given to their babies immediately after birth ('HIVNET 012 regimen') compared with ZDV given to mothers during labour and to their babies for a week after birth resulted in lower HIV infection rates at 4-8 weeks (Efficacy 41.00%; 95% CI 11.60 to 70.40), 3-4 months (Efficacy 39.00%; 95% CI 11.56 to 66.44), 12 months (Efficacy 36.00%; 95% CI 8.56 to 63.44) and 18 months (Efficacy 39.00%; 95% CI 13.52 to 64.48). In addition, the NVP regimen significantly reduced the risk of HIV infection or death at 4-8 weeks (Efficacy 42.00%; 95% CI 14.56 to 69.44), 3 to 4 months (Efficacy 40.00%; 95% CI 14.52 to 65.48), 12 months (Efficacy 32.00%; 95% CI 8.48 to 55.52) and 18 months (Efficacy 33.00%; 95% CI 9.48 to 56.52). The 'HIVNET 012 regimen' plus ZDV given to babies for 1 week after birth compared with the 'HIVNET 012 regimen' alone did not result in a statistically significant difference in HIV infection at 4 to 8 weeks.A single dose of NVP given to babies immediately after birth plus ZDV given to babies for 1 week after birth compared with a single dose of NVP given to babies only significantly reduced the HIV infection rate at 4 to 8 weeks (Efficacy 37.00%; 95% CI 3.68 to 70.32). Five trials in non-breastfeeding populations found that:In a population in which mothers were receiving 'standard' ARV for HIV infection a single dose of NVP given to mothers in labour plus a single dose of NVP given to babies immediately after birth ('HIVNET 012 regimen') compared with placebo did not result in a statistically significant difference in HIV infection rates at birth and at 4 to 8 weeks. The 'Thai CDC regimen' compared with the 'HIVNET 012 regimen' did not result in a significant difference in HIV infection at 4 to 8 weeks.A single dose of NVP given to babies immediately after birth compared to ZDV given to babies for the first 6 weeks of life did not result in a significant difference in HIV infection rates at 4-8 weeks and 3 to 4 months.ZDV plus 3TC given to mothers in labour and for a week after delivery and to their infants for a week after birth (similar to 'PETRA regimen B') compared with NVP given to mothers in labour and immediately after delivery plus a single dose of NVP to their babies immediately after birth (similar to 'HIVNET 012 regimen') did not result in a significant difference in the HIV infection rate at 4 to 8 weeks.

Determinants of Fitness App Usage and Moderating Impacts of Education-, Motivation-, and Gamification-Related App Features on Physical Activity Intentions: Cross-sectional Survey Study.

Background: Smartphone fitness apps are considered promising tools for promoting physical activity and health. However, it is unclear which user-perceived factors and app features encourage users to download apps with the intention of being physically active. Objective: Building on the second version of the Unified Theory of Acceptance and Use of Technology, this study aims to examine the association of the seven determinants of the second version of the Unified Theory of Acceptance and Use of Technology with the app usage intentions of the individuals and their behavioral intentions of being physically active as well as the moderating effects of different smartphone fitness app features (ie, education, motivation, and gamification related) and individual differences (ie, age, gender, and experience) on these intentions. Methods: Data from 839 US residents who reported having used at least one smartphone fitness app were collected via a web-based survey. A confirmatory factor analysis was performed, and path modeling was used to test the hypotheses and explore the influence of moderators on structural relationships. Results: The determinants explain 76% of the variance in the behavioral intention to use fitness apps. Habit (β=.42; P<.001), performance expectancy (β=.36; P<.001), facilitating conditions (β=.15; P<.001), price value (β=.13; P<.001), and effort expectancy (β=.09; P=.04) were positively related to behavioral intention to use fitness apps, whereas social influence and hedonic motivation were nonsignificant predictors. Behavioral intentions to use fitness apps were positively related to intentions of being physically active (β=.12; P<.001; R2=0.02). Education-related app features moderated the association between performance expectancy and habit and app usage intentions; motivation-related features moderated the association of performance expectancy, facilitating conditions, and habit with usage intentions; and gamification-related features moderated the association between hedonic motivation and usage intentions. Age moderated the association between effort expectancy and usage intentions, and gender moderated the association between performance expectancy and habit and usage intentions. User experience was a nonsignificant moderator. Follow-up tests were used to describe the nature of significant interaction effects. Conclusions: This study identifies the drivers of the use of fitness apps. Smartphone app features should be designed to increase the likelihood of app usage, and hence physical activity, by supporting users in achieving their goals and facilitating habit formation. Target group-specific preferences for education-, motivation-, and gamification-related app features, as well as age and gender differences, should be considered. Performance expectancy had a high predictive power for intended usage for male (vs female) users who appreciated motivation-related features. Thus, apps targeting these user groups should focus on goal achievement-related features (eg, goal setting and monitoring). Future research could examine the mechanisms of these moderation effects and their long-term influence on physical activity.

Prevalence and management of chronic insomnia in Swiss primary care: Cross-sectional data from the "Sentinella" practice-based research network.

We investigated the prevalence and treatment of patients with chronic insomnia presenting to Swiss primary care physicians (PCPs) part of "Sentinella", a nationwide practice-based research network. Each PCP consecutively asked 40 patients if they had sleep complaints, documented frequency, duration, comorbidities, and reported ongoing treatment. We analysed data of 63% (83/132) of the PCPs invited. The PCPs asked 76% (2,432/3,216) of included patients about their sleep (51% female); 31% (761/2,432) of these had had insomnia symptoms; 36% (875/2,432) had current insomnia symptoms; 11% (269/2,432) met the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for chronic insomnia (61% female). In all, 75% (201/269) of patients with chronic insomnia had comorbidities, with 49% (99/201) reporting depression. Chronic insomnia was treated in 78% (209/269); 70% (188/268) took medication, 38% (102/268) benzodiazepines or benzodiazepine receptor agonists, 32% (86/268) took antidepressants. Only 1% (three of 268) had been treated with cognitive behavioural therapy for insomnia (CBT-I). A third of patients presenting for a non-urgent visit in Swiss primary care reported insomnia symptoms and 11% met the DSM-5 criteria for chronic insomnia. Hypnotics were the most common treatment, but almost no patients received first-line CBT-I. Reducing the burden of insomnia depends on disseminating knowledge about and access to CBT-I, and encouraging PCPs to discuss it with and offer it as a first-line treatment to patients with chronic insomnia.

Domestic violence in pregnancy: prevalence and characteristics of the pregnant woman.

Aims and objectives: To determine the prevalence of domestic violence (physical, psychological or sexual) during pregnancy and to characterise these women. Background: Pregnant women are not immune to domestic violence and therefore may be subject to any form of physical, psychological or sexual violence by partners. Health professionals' knowledge and awareness are important in the identification and intervention of pregnant women who experience domestic violence. Methods: Quantitative, descriptive, correlational study, using a nonprobabilistic convenience sample consisting of a total of 852 postpartum women, of whom 370 were experiencing domestic violence according to the criteria adopted through the modified scale of prevalence, applied between February-June 2012 in two Portuguese public health institutions. Authorisation was given by the Ethics Committees/Administration Councils of both institutions involved and the National Committee of Data Protection. Results: The prevalence of DV during pregnancy was 43·4% (physical violence - 21·9%; psychological violence - 43·2%; and sexual violence - 19·6%). These women had the following profile: immigrant (OR = 5·70; IC95% 3·32-9·78), non-Caucasian (OR = 6·27; IC95% 3·76-10·46), single/divorced/widowed (OR = 2·28; IC95% 1·70-3·05), academic qualifications up to year 9 (OR = 4·94; IC95% 3·31-7·37); between 10-12 years of schooling (OR = 2·36; IC95% 1·70-3·29); unemployed (OR = 2·01; IC95% 1·50-2·69); and with a monthly income <1000 euros (OR = 1·90; IC95% 1·44-2·50). Through logistic regression, the following protective factors have been identified: nationality (Portuguese), race (Caucasian) and place of residence (city). Conclusions: Almost half of the sample had experienced some form of domestic violence. This is associated with certain sociodemographic factors identified in the study. Psychological violence was the most prevalent during pregnancy. Relevance to clinical practice: Knowledge of the prevalence and characteristics of pregnant women who experience domestic violence is of paramount importance in planning appropriate strategies for their needs during pregnancy. Results indicate the need for nurses to intervene when warning signs of domestic violence against pregnant women are detected.

Association of neighbourhood migrant density and risk of non-affective psychosis: a national, longitudinal cohort study.

Background: Elevated risk of psychotic disorders in migrant groups is a public mental health priority. We investigated whether living in areas of high own-region migrant density was associated with reduced risk of psychotic disorders among migrants and their children, and whether generation status, probable visible minority status, or region-of-origin affected this relationship. Methods: We used the Swedish registers to identify migrants and their children born between Jan 1, 1982, and Dec 31, 1996, and living in Sweden on or after their 15th birthday. We tracked all included participants from age 15 years or date of migration until emigration, death, or study end (Dec 31, 2016). The outcome was an ICD-10 diagnosis of non-affective psychosis (F20-29). We calculated own-region and generation-specific own-region density within the 9208 small areas for market statistics neighbourhoods in Sweden, and estimated the relationship between density and diagnosis of non-affective psychotic disorders using multilevel Cox proportional hazards models, adjusting for individual confounders (generation status, age, sex, calendar year, lone dwelling, and time since migration [migrants only]), family confounders (family income, family unemployment, and social welfare), and neighbourhood confounders (deprivation index, population density, and proportion of lone dwellings), and using the Akaike information criterion (AIC) to compare model fit. Findings: Of 468 223 individuals included in the final cohort, 4582 (1·0%) had non-affective psychotic disorder. Lower own-region migrant density was associated with increased risk of psychotic disorders among migrants (hazard ratio [HR] 1·05, 95% CI 1·02-1·07 per 5% decrease) and children of migrants (1·03, 1·01-1·06), after adjustment. These effects were stronger for probable visible minority migrants (1·07, 1·04-1·11), including migrants from Asia (1·42, 1·15-1·76) and sub-Saharan Africa (1·28, 1·15-1·44), but not migrants from probable non-visible minority backgrounds (0·99, 0·94-1·04). Among migrants, adding generation status to the measure of own-region density provided a better fit to the data than overall own-region migrant density (AIC 36 103 vs 36 106, respectively), with a 5% decrease in generation-specific migrant density corresponding to a HR of 1·07 (1·04-1·11). Interpretation: Migrant density was associated with non-affective psychosis risk in migrants and their children. Stronger protective effects of migrant density were found for probable visible minority migrants and migrants from Asia and sub-Saharan Africa. For migrants, this risk intersected with generation status. Together, these results suggest that this health inequality is socially constructed.

Integrating Mental Health and HIV Services in Zimbabwean Communities: A Nurse and Community-led Approach to Reach the Most Vulnerable.

Alcohol use and depression negatively impact adherence, retention in care, and HIV progression, and people living with HIV (PLWH) have disproportionately higher depression rates. In developing countries, more than 76% of people with mental health issues receive no treatment. We hypothesized that stepped-care mental health/HIV integration provided by multiple service professionals in Zimbabwe would be acceptable and feasible. A three-phase mixed-method design was used with a longitudinal cohort of 325 nurses, community health workers, and traditional medicine practitioners in nine communities. During Phase 3, 312 PLWH were screened by nurses for mental health symptoms; 28% were positive. Of 59 PLWH screened for harmful alcohol and substance use, 36% were positive. Community health workers and traditional medicine practitioners screened 123 PLWH; 54% were positive for mental health symptoms and 29% were positive for alcohol and substance abuse. Findings indicated that stepped-care was acceptable and feasible for all provider types.

Centralized patient-reported outcome data collection in transplantation is feasible and clinically meaningful.

Background: Allogeneic hematopoietic cell transplantation (HCT) cures many patients, but often with the risk of late effects and impaired quality of life. The value of quantifying patient-reported outcomes (PROs) is increasingly being recognized, but the routine collection of PROs is uncommon. This study evaluated the feasibility of prospective PRO collection by an outcome registry at multiple time points from unselected HCT patients undergoing transplantation at centers contributing clinical data to the Center for International Blood and Marrow Transplant Research (CIBMTR), and then it correlated the PRO data with clinical and demographic data. Methods: The Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), 36-Item Short Form Health Survey (SF-36), and Pediatric Quality of Life Inventory measures were administered before HCT, on day 100, and at 6 and 12 months. Patients were recruited by the transplant center, but posttransplant PRO collection was managed centrally by the CIBMTR. Results: There were 580 eligible patients, and 390 (67%) enrolled. Feasibility was shown by high time-specific retention rates (176 of 238 at 1 year or 74%) and participant satisfaction. Factors associated with higher response rates were an age > 50 years (odds ratio [OR], 1.58; 95% confidence interval [CI], 1.03-2.41; P = .0355), white race (OR, 4.61; 95% CI, 2.66-7.99; P < .0001), and being married (OR, 2.28; 95% CI, 1.42-3.65; P = .0006) for adults and a higher family income for children (OR, 4.99; 95% CI, 2.12-11.75; P = .0002). Importantly, pre-HCT PRO scores independently predicted survival after adjustments for patient-, disease-, and transplant-related factors. The adjusted probabilities of 1-year survival were 56%, 67%, 75%, and 76% by increasing quartiles of the pre-HCT FACT-BMT score and 58%, 72%, 62%, and 82% by increasing quartiles of the pre-HCT SF-36 physical component score. Conclusions: A hybrid model of local consent for centralized PRO collection is feasible, and pretransplant PROs provide critical prognostic information for HCT outcomes.

An objective assessment of children's exposure to brand marketing in New Zealand (Kids'Cam): a cross-sectional study.

Background: Marketing promotes values of consumerism and overconsumption, and negatively affects children's wellbeing and psychological development. The threat marketing poses to planetary health is just being realised. However, little is known about children's exposure to marketing at an aggregate level. Using an objective method of wearable cameras, we aimed to determine the nature and extent of children's exposure to marketing. Methods: Kids'Cam was a cross-sectional study of children aged 11-13 years in New Zealand, from which we randomly selected a sample of 90 children. Children wore cameras from when they woke up until they went to sleep for four consecutive days (Thursday-Sunday) that captured images at an angle of 136° every 7 s for exposure to marketing. Marketing brands were categorised into three groups: core food and social marketing messages, harmful commodities (eg, non-core food, alcohol, and gambling), or other. Exposure rates by marketing medium, setting, and product category were calculated using negative binomial regression models. Findings: From June 21, 2014, to June 30, 2015, we recruited 168 children, and randomly selected data from 90 children for the present study. Children in this study were exposed to a mean of 554 brands per 10 h day (95% CI 491-625), nearly a brand a minute, through multiple mediums (predominantly brand labels [36% of exposures] and product packaging [22%]) and mostly in schools (43%) and at home (30%). Food and beverages (20% of exposures) were the dominant product category. The most pervasive marketing brands typically sold a range of products across more than one product category (eg, children were exposed to Nike on average 20 exposures per day). Children were exposed to more than twice as many harmful commodities (mean 76 per 10 h day [95% CI 55-105]) as core food and social marketing messages (32 [26-39]) per day. Interpretation: We found that children are repeatedly exposed to marketing through multiple mediums and across all settings, and our findings suggests that marketing privileges particular messages, for example, marketing of harmful commodities. Given the key role marketing plays in establishing and supporting consumption norms, and perpetuating the normalisation of overconsumption which contributes to environmental degradation, these findings suggest an urgent need to reduce marketing to promote planetary health.

Catastrophic health expenditure, social protection coverage, and financial coping strategies in adults with symptoms of chronic respiratory diseases in Kenya: a cross-sectional study.

Background: Despite the socioeconomic consequences of an increasing burden of chronic respiratory diseases, there is little evidence on the incidence and determinants of catastrophic health expenditure (CHE) in people with chronic respiratory disease symptoms in Kenya. We aimed to generate this evidence by collecting data on medical and non-medical costs, lost income, social protection coverage, and financial coping strategies for such people in Kenya. Methods: We conducted a cross-sectional survey of consecutively recruited adults seeking care for chronic respiratory disease symptoms at five public health-care facilities in Meru County, Kenya, between Sept 5, 2019, and Oct 1, 2020. Patient costs, National Health Insurance Fund (NHIF) coverage, financial coping strategies, and sociodemographic and clinical data were collected from surveys and medical records. The main study outcomes were the incidence of, and social and health factors associated with, CHE in this cohort. CHE incidence was calculated through the WHO threshold of direct out-of-pocket costs being greater than 10% of a household's monthly total expenditure. Multivariable logistic regression analyses generated adjusted odds ratios (aORs) with 95% CIs of health and social factors associated with CHE, including age, sex, education level, tobacco use, income, being accompanied, poverty level (with the first quintile being the richest to the fifth quintile being the poorest), NHIF usage, coping strategies, final diagnosis, and health system level at which they were seeking care. Findings: Of 319 eligible people invited, 296 (93%) consented to participate and completed surveys. Mean total cost was 1062 Kenyan shillings (KES; 95% CI 896-1228; US$9·1), of which 40·0% was due to direct non-medical costs (KES 425, 95% CI 361-489; $3·7), 36·7% to direct out-of-pocket medical costs (KES 390, 324-456; $3·1), and 23·3% to lost income (KES 247, 153-341, $2·1). 212 (72%) of 296 participants did not have NHIF, 282 (95%) of 296 used coping strategies during care-seeking, and 59 (20%) of 296 were accompanied by a carer during health-care seeking. 76 (26%) of 296 participants had CHE. CHE was associated with being aged 30-44 years old (aOR 2·6, 95% CI 1·3-5·3, p=0·010), being female (1·8, 1·3-2·7, p=0·0021), having higher than secondary school education (1·6, 1·1-2·3, p=0·0083), being accompanied during health-care-seeking visits (3·2, 1·7-5·9, p<0·0001), belonging to the second poverty quintile (2·0, 1·9-2·1, p<0·0001), and seeking care from subcounty hospitals (9·7, 9·6-9·8, p<0·0001) and county hospitals (25·1, 15·7-40·2, p<0·0001). Interpretation: These findings suggest a sizeable burden of CHE in people seeking care for chronic respiratory disease symptoms in Meru County in Kenya, driven by socioeconomic and sex inequalities and impaired access to health care and social protection.

Combat sports and wellbeing: advancing health and inclusion in athletes and practitioners. An opinion paper

Historically, combat sports have been predominantly conceptualized within the framework of elite competition, emphasizing physical aptitude, technical proficiency, and strategic execution (1-3). Despite their traditional and peculiar constitutions and developments, disciplines such as judo, karate, taekwondo, wrestling, fencing, boxing, and mixed martial arts have commonly been associated with high-performance athletes striving for competitive excellence on national and international stages (1, 4-6). However, contemporary discourse increasingly recognizes their expansive role in contributing to physical and psychological well-being, and social inclusion of the practitioners (7, 8). This paradigmatic shift underscores the capacity of combat sports to function as inclusive and accessible modalities for fostering multidimensional health benefits across diverse populations, including individuals with disabilities and other marginalized groups (9-13).The interdisciplinary exploration of physical activity and health highlights the intricate interrelationship between structured sports engagement and holistic well-being (14). Whilst conventional team and individual sports have long been acknowledged for their physiological and psychosocial benefits, combat sports exhibit distinct characteristics that might amplify these advantages (15, 16). Within combat sports, the synergistic interplay of rigorous physical conditioning, the cognitive engagement, adherence to rules, competition dynamics, respect, externalizing emotions regulation, are intertwined with pedagogical and philosophical values, thus presenting a unique framework for enhancing psychological resilience, cognitive adaptability, and emotional control. Consequently, the systematic practice of combat sports has been increasingly examined as a way of promoting mental health, stress modulation, and social cohesion (17, 18).The inclusive nature of many combat sports programmes further accentuates their relevance in dismantling stereotypes, facilitating integration, and fostering equity and social integration (19-21). In fact, they demonstrated significant adaptability to accommodate individuals with disabilities (e.g., physical impairments, developmental, emotional, intellectual disorders), thereby ensuring equitable access and fostering empowerment (9, 22). Adapted judo, para-taekwondo, and other modified combat disciplines provide individuals with disabilities a structured platform to engage in physical activity, cultivate self-efficacy, and develop meaningful social connections within a supportive and adaptive environment (23). From a public health perspective, the integration of combat sports within community-based health initiatives offers a compelling opportunity to engage populations that may not traditionally participate in structured physical activity programmes (7, 8, 19). The distinctive accessibility of combat sports, which cater to practitioners of all skill levels (e.g., from novices to elite athletes) sets them apart from many other sports. While their structured progression, adaptability, and emphasis on holistic development make them a viable option for lifelong and intergenerational participation (19, 24, 25), the mentorship and pedagogical frameworks cultivate positive role modeling, discipline, and intrinsic motivation, which are integral for sustaining long-term adherence to health-promoting behaviors (8).Furthermore, the intersection between combat sports and mental health has increasingly emerged as a focal point within academic and clinical research (17) with empirical evidence suggesting an association between participation and enhanced self-regulation and self-efficacy, and reduction in anxiety and depressive symptomatology (8, 26, 27). In necessitating sustained focus, adaptability, and emotional equilibrium, combat sports inherently require cognitive and affective demands, which align closely with established psychological frameworks that underpin mental well-being (28, 29). Moreover, the integration of mindfulness techniques, stress management strategies, and resilience-building paradigms within combat sports training substantiates their potential as a non-pharmacological intervention for addressing various mental health challenges (e.g., autism spectrum and oppositional defiant disorders) (30, 31).Despite these advantages, the discourse surrounding combat sports and well-being necessitates a critical examination of inherent risks and potential challenges. Issues related to injury risk, hypercompetitive environments, eating disorders, sexual harassment, and the psychological stressors associated with high-intensity training warrant careful scrutiny (32-36). The implementation of evidence-based injury prevention protocols, the establishment of ethically responsible coaching methodologies, and the promotion of safe training environments are imperative to ensure that the benefits of combat sports are maximized while minimizing adverse outcomes. Against this backdrop, this opinion paper seeks to examine the role of combat sports in advancing health and social inclusion among athletes and practitioners. Through a synthesis of contemporary empirical findings, theoretical paradigms, and applied insights, this paper aims to contribute to the evolving discourse on the potential of combat sports as a catalyst for holistic well-being. By delineating the multidimensional impact of combat sports on physical, psychological, and social health, this paper endeavors to underscore their transformative potential as an instrument for fostering individual and community well-being within different populations. DiscussionWhilst an expanding body of research and an evolution in scholarly discourse is recognizing the combat sports’ broader implications for holistic well-being (30, 37), a rigorous evaluation of the investigation methodologies, the validity of hypotheses, and the translational potential of recent findings is necessary to contextualize their significance within the sports and public health sciences, considering their strengths, weaknesses, opportunities, and threats (Figure 1).----------------------------------------ADD FIGURE 1 ABOUT HERE----------------------------------------Empirical evidence robustly shows the positive impact of combat sports on physical fitness, motor coordination, and cardiovascular health (3, 38). These benefits are attributed to the high-intensity, intermittent nature of combat sports training, which enhances aerobic and anaerobic endurance, muscular strength, and neuromuscular control (39). However, concerns regarding injury risk, particularly in striking and contact-intensive disciplines such as boxing, taekwondo, and mixed martial arts, necessitate continued research into injury mitigation strategies, particularly those targeting concussion and repetitive head trauma (6, 35, 40, 41). Moreover, many combat sports have developed styles with reduced or simulated contact to minimize injury risk. For example, the French "boxe éducative" emphasizing technique and control, penalizing any violent behaviors (42) and the value and application of kata (i.e., forms; prearranged, pattern practices) to learning and adopting judo technique in a safe way educating the athlete culturally, to enrich her/him as a person (43).Beyond physical health, recent studies highlight the psychological benefits of combat sports, including reductions in anxiety and depression and improvements in self-efficacy, emotional regulation, resilience, and stress management (27, 44-47). Therefore, combat sports-based interventions for individuals with mental health conditions have yielded promising outcomes (23). Despite these encouraging findings, variability in study designs, participant demographics, and intervention protocols limits their external validity, underscoring the need for further rigorously controlled investigations. Furthermore, some authors claimed that combat sport athletes might present symptoms of low energy availability and high anxiety levels associated with competition- and injury-related psychological stressors, deficits in executive functions and neuropsychological impairments associated with occurrence of concussions, disordered eating and eating disorders associated with weight-loss, and might suffer offensive, frightening, hostile, degrading, humiliating experiences, or sexual harassment, which urge safeguarding actions (32-36).The role of combat sports in fostering social inclusion has gained empirical support, particularly in programmes aimed at individuals with disabilities and marginalized communities (25, 48). For instance, a recent systematic review shows that judo interventions adapted for intellectual disabilities help improve social integration and self-perception and enhance participants' quality of life (49). The development of para-combat sports demonstrates enhanced physical and motor abilities while providing psychosocial benefits to various populations with different disabilities, promoting social integration, self-perception, and community belonging (50, 51). However, longitudinal research is needed to assess the long-term retention rates and sustainability of these benefits. Furthermore, there is a need of studies focused on the most appropriate adapted rules to achieve a fairer competition for ensuring a sense of success in individuals with physical, emotional, mental, hearing or visual impairments participating in adapted sports competitions at local, national, and international levels. Methodological approaches in combat sports research encompass experimental, longitudinal, qualitative, and systematic review designs. While randomized controlled trials remain the gold standard for establishing causality, their application in combat sports research is constrained by ethical concerns, logistical challenges, and the inherently dynamic nature of training environments (52, 53). Consequently, many studies rely on observational designs, which, despite their value in identifying associations, are susceptible to confounding variables and biases (24, 54).Qualitative methodologies have provided critical insights into the lived experiences of combat sports practitioners, offering perspectives on psychological and social dimensions that are often overlooked in quantitative studies (28). Ethnographic research has been particularly instrumental in elucidating the role of combat sports in shaping identity, discipline, and personal development (55). However, limitations in reproducibility and generalizability highlight the need for mixed-methods approaches to generate a more comprehensive understanding of combat sports' impact (25, 56).Additionally, the incorporation of biometric and neurocognitive assessments, such as heart rate variability analysis, functional MRI, and salivary cortisol measurements, has advanced our understanding of the physiological and psychological mechanisms underlying combat sports participation (47, 57, 58). Despite their objective precision, these techniques often face challenges related to cost, accessibility, and limited sample sizes, necessitating the development of scalable and cost-effective methodologies for broader research application. Finally, recent studies show that virtual reality (VR) technology and digital platforms are increasingly becoming part of combat sports training methods. Due to COVID-19 restrictions, martial arts schools and organizations implemented hybrid or online training models, which allowed athletes to stay engaged. VR boxing programmes provide users with virtual sparring simulations to enhance their motor skills without needing physical interaction. Initial results indicate that VR training enhances response behavior in karate athletes (59). Digital adaptations offer great potential, especially for people with limited mobility or remote locations. However, further studies are necessary to prove their enduring effects on physical health and psychological and social aspects (59-61).Strengths and Weaknesses of Scientific HypothesesThe hypothesis that combat sports confer multidimensional health benefits is strongly supported by empirical evidence spanning physiological, psychological, and social domains (8, 62-64). The integration of physical exertion, cognitive engagement, and structured discipline inherent in combat sports aligns with established theories of exercise psychology, neuroplasticity, and social identity formation (65, 66). This multidimensional perspective provides a robust theoretical foundation for advocating combat sports as a health-promoting activity. Nevertheless, several limitations warrant consideration. The heterogeneity of disciplines, which vary highly in intensity, contact level, and training methodologies, is often inadequately addressed in research, leading to overgeneralized conclusions (17, 39). Often underexamined, individual differences in personality, motivation, and previous trauma history may strongly moderate the psychological outcomes of combat sports participation (35, 67, 68).Additionally, a research focus is needed on concerns regarding the potential for adverse psychological effects (e.g., anxiety, depression, disordered eating behaviors, burnout, and decreased self-esteem), particularly in competitive environments where performance pressure, extreme weight-cutting practices, and aggressive coaching styles are prevalent (69, 70). Indeed, a balanced perspective that considers both benefits and risks is essential for the development of evidence-based recommendations (10, 71).Future DirectionsTo enhance the field, future research should prioritize well-structured longitudinal studies that assess the long-term impact of combat sports participation on physical, psychological, and social health. Standardization of outcome measures, intervention protocols, and participant demographics would facilitate cross-study comparisons and strengthen the reliability of findings (72, 73). Moreover, interdisciplinary collaborations incorporating sports science, psychology, and sociology could provide a more holistic perspective on combat sports' broader implications on practitioners (74).From a policy perspective, to yield valuable insights into combat sports’ practical applications research should investigate their efficacy within public health, educational, and rehabilitation initiatives, particularly for underserved and vulnerable populations (23, 75, 76).Furthermore, while safety remains a primary concern, advancements in protective equipment, training methodologies, education for athletes, coaches, referees and tournament directors, and regulatory frameworks should be continually evaluated to optimize benefits while mitigating risks (40, 41, 58, 77, 78). Ethical considerations, particularly concerning athlete well-being and inclusive participation, should remain a central focus in both research and practical implementation (17, 34, 36).Therefore, key research challenges to be addressed are: 1. Injury risk and safety: a need for injury prevention strategies, especially for concussions and head trauma in striking sports. 2. Psychological wellbeing: risks of stress, anxiety, burnout, and negative self-perception in competitive environments. 3. Inclusion and accessibility: a need for more research on long-term social and psychological benefits for marginalized groups and individuals with disabilities. 4. Methodological limitations: lack of standardized protocols, variability in study designs, and limited reproducibility of findings. 5. Ethical and regulatory issues: concerns over coaching practices, extreme weight-cutting, and athlete wellbeing in high-pressure environments. 6. Technological innovations: more research required on the effectiveness of VR and digital training tools in combat sports. 7. Public health and policy: exploration of combat sports' role in health initiatives, rehabilitation, and educational programs. ConclusionThe evolving discourse on combat sports highlights their potential as a multidimensional tool for well-being promotion. While a substantial body of evidence supports their benefits, a critical examination of methodological limitations, scientific hypotheses, and practical applications is essential for further refine our understanding and enhance their effectiveness. Finally, this article makes a significant contribution not only to the field of martial arts but also to public health and sports psychology. Its interdisciplinary approach calls for scientific collaboration and methodological rigor, reinforces the need for evidence-based policies and can serve as a valuable guide for researchers and policymakers looking to integrate combat sports into strategies for promoting health and social inclusion.

Rumination and impaired cortisol recovery following a social stressor in adolescent depression.

Response styles theory promotes rumination as a central cognitive construct driving negative mood and depression, and past research suggests that at least part of the mechanism driving rumination's depressogenic effect is through inhibiting the individual's ability to shift attentional focus away from negative environmental stimuli. In the current study, we hypothesized that high trait rumination would be associated with impaired recovery of the body's biological response to psychological stress. In a community sample of depressed (n = 31) and non-depressed (n = 33) adolescents we assessed rumination and the more adaptive trait of distraction and problem-solving with the Children's Response Styles Questionnaire (CRSQ; Abela 2000), and diagnostic status was confirmed using the Child and Adolescent Schedule of Affective Disorders and Schizophrenia (K-SADS; Kaufman et al. Journal of the American Academy of Child and Adolescent Psychiatry 36:980-988, 1997). Participants completed the Trier Social Stress Test (TSST; Kirschbaum et al. Neuropsychobiology 28:76-81, 1993), and the focus of our analyses was the change in salivary cortisol concentration between peak cortisol output (25 min post-stressor) and a sample taken during the "Recovery" period 65 minutes post-stressor. Consistent with the predictions of response style theory, among the depressed adolescents only, high trait rumination was associated with delayed post-stressor cortisol recovery, whereas high trait distraction and problem-solving was associated with more rapid recovery. In contrast, response styles were not associated with cortisol recovery in the non-depressed group. These findings implicate impaired post-stress cortisol recovery as a potential mechanism underlying the pathological effect of rumination on the development and maintenance of Major Depressive Disorder (MDD).

Iron deficiency without anemia is associated with anger and fatigue in young Japanese women.

Iron deficiency without anemia (IDNA), the most prevalent nutritional deficiency worldwide, affects young women of reproductive age. This study aimed to elucidate the relationship between IDNA and mental and somatic symptoms including anger and fatigue using the Japanese version of the Cornell Medical Index Health Questionnaire (CMI-J). Data regarding demographic characteristics, anthropometry, hematological, and biochemical indices of the iron status, frequencies of selected food intakes assessed by self-administered food frequency questionnaires (FFQs), frequencies of nonspecific symptoms, and grades of neurotic tendencies assessed by CMI-J were collected from 76 young women aged 18-22 years living in the metropolitan area of Tokyo, Japan. The subjects were classified as having IDNA (hemoglobin (Hb)≥12 g/dL and serum ferritin<20 ng/mL; n=29), having iron deficiency anemia (IDA) (Hb<12 g/dL and serum ferritin<20 ng/mL; n=10), or having a normal iron status (Hb≥12 g/dL and serum ferritin≥20 ng/mL; n=36). One subject was excluded from the analyses because of Hb<12 g/dL and serum ferritin≥20 ng/mL. Fisher's protected least significant difference and the Dwass-Steel-Chritchlow-Fligner multiple comparison tests were used to compare the data of the three groups. P values<0.05 were considered significant. Sections M-R (mental complaints) were significantly higher in the IDNA subjects than in the normal subjects. No significant difference in CMI scores was found between the normal and IDA subjects. Sections I (fatigability), Q (anger), and R (tension) were significantly higher in the IDNA subjects than in the normal subjects, regardless of no significant differences between the normal and IDA subjects in those sections. Young women with IDNA demonstrated a significantly higher proportion of neurotic tendencies (grades II-IV). The intake frequency score of canned or bottled green tea fortified with vitamin C was significantly higher in the IDNA subjects than the IDA subjects. The findings suggest that IDNA may be a risk factor for anger, fatigue, and tension in women of childbearing age.
