The global burden of perinatal common mental health disorders and substance use among migrant women: a systematic review and meta-analysis.
Background: There are one billion migrants globally, of whom 82 million are forced migrants. Pregnant migrants face pre-migration stressors such as conflict, transit stressors including poverty, and post-migration stressors including navigating the immigration system; these stressors can make them vulnerable to mental illness. We aimed to assess the global prevalence of and risk factors for perinatal mental health disorders or substance use among women who are migrants.
Methods: In this systematic review and meta-analysis, we searched OVID MEDLINE, Embase, PsycINFO, CENTRAL, Global Health, Scopus, and Web of Science for studies published from database inception until July 8, 2022. Cohort, cross-sectional, and interventional studies with prevalence data for any mental illness in pregnancy or the postnatal period (ie, up to a year after delivery) or substance use in pregnancy were included. The primary outcome was the prevalence of perinatal common mental health disorders among women who are migrants, globally. Data for study quality and risk factors were also extracted. A random-effects meta-analysis was used to calculate pooled prevalence estimates, when appropriate. Sensitivity analyses were conducted according to study quality, sample representativeness, and method of outcome assessment. Risk factor data were synthesised narratively. This study is registered with PROSPERO, CRD42021226291.
Findings: 18 650 studies were retrieved, of which 135 studies comprising data from 621 995 participants met the inclusion criteria. 123 (91%) of 135 studies were conducted in high-income host countries. Five (4%) of 135 studies were interventional, 40 (30%) were cohort, and 90 (66%) were cross-sectional. The most common regions of origin of participants were South America, the Middle East, and north Africa. Only 26 studies presented disaggregated data for forced migrants or economic migrants. The pooled prevalence of perinatal depressive disorders was 24·2% (range 0·5-95·5%; I2 98·8%; τ2 0·01) among all women who are migrants, 32·5% (1·5-81·6; 98·7%; 0·01) among forced migrants, and 13·7% (4·7-35·1; 91·5%; 0·01) among economic migrants (p<0·001). The pooled prevalence of perinatal anxiety disorders was 19·6% (range 1·2-53·1; I2 96·8%; τ2 0·01) among all migrants. The pooled prevalence of perinatal post-traumatic stress disorder (PTSD) among all migrant women was 8·9% (range 3·2-33·3; I2 97·4%; τ2 0·18). The pooled prevalence of perinatal PTSD among forced migrants was 17·1% (range 6·5-44·3; I2 96·6%; τ2 0·32). Key risk factors for perinatal depression were being a recently arrived immigrant (ie, approximately within the past year), having poor social support, and having a poor relationship with one's partner.
Interpretation: One in four women who are migrants and who are pregnant or post partum experience perinatal depression, one in five perinatal anxiety, and one in 11 perinatal PTSD. The burden of perinatal mental illness appears higher among women who are forced migrants compared with women who are economic migrants. To our knowledge, we have provided the first pooled estimate of perinatal depression and PTSD among women who are forced migrants. Interpreting the prevalence estimate should be observed with caution due to the very wide range found within the included studies. Additionally, 66% of studies were cross-sectional representing low quality evidence. These findings highlight the need for community-based routine perinatal mental health screening for migrant communities, and access to interventions that are culturally sensitive, particularly for forced migrants who might experience a higher burden of disease than economic migrants.

Exercise training undertaken by people within 12 months of lung resection for non-small cell lung cancer.
Background: Decreased exercise capacity and health-related quality of life (HRQoL) are common in people following lung resection for non-small cell lung cancer (NSCLC). Exercise training has been demonstrated to confer gains in exercise capacity and HRQoL for people with a range of chronic conditions, including chronic obstructive pulmonary disease and heart failure, as well as in people with prostate and breast cancer. A programme of exercise training may also confer gains in these outcomes for people following lung resection for NSCLC. This systematic review updates our 2013 systematic review.
Objectives: The primary aim of this review was to determine the effects of exercise training on exercise capacity and adverse events in people following lung resection (with or without chemotherapy) for NSCLC. The secondary aims were to determine the effects of exercise training on other outcomes such as HRQoL, force-generating capacity of peripheral muscles, pressure-generating capacity of the respiratory muscles, dyspnoea and fatigue, feelings of anxiety and depression, lung function, and mortality.
Search methods: We searched for additional randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2019, Issue 2 of 12), MEDLINE (via PubMed) (2013 to February 2019), Embase (via Ovid) (2013 to February 2019), SciELO (The Scientific Electronic Library Online) (2013 to February 2019), and PEDro (Physiotherapy Evidence Database) (2013 to February 2019).
Selection criteria: We included RCTs in which participants with NSCLC who underwent lung resection were allocated to receive either exercise training, which included aerobic exercise, resistance exercise, or a combination of both, or no exercise training.
Data collection and analysis: Two review authors screened the studies and identified those eligible for inclusion. We used either postintervention values (with their respective standard deviation (SD)) or mean changes (with their respective SD) in the meta-analyses that reported results as mean difference (MD). In meta-analyses that reported results as standardised mean difference (SMD), we placed studies that reported postintervention values and those that reported mean changes in separate subgroups. We assessed the certainty of evidence for each outcome by downgrading or upgrading the evidence according to GRADE criteria.
Main results: Along with the three RCTs included in the original version of this review (2013), we identified an additional five RCTs in this update, resulting in a total of eight RCTs involving 450 participants (180 (40%) females). The risk of selection bias in the included studies was low and the risk of performance bias high. Six studies explored the effects of combined aerobic and resistance training; one explored the effects of combined aerobic and inspiratory muscle training; and one explored the effects of combined aerobic, resistance, inspiratory muscle training and balance training. On completion of the intervention period, compared to the control group, exercise capacity expressed as the peak rate of oxygen uptake (VO2peak) and six-minute walk distance (6MWD) was greater in the intervention group (VO2peak: MD 2.97 mL/kg/min, 95% confidence interval (CI) 1.93 to 4.02 mL/kg/min, 4 studies, 135 participants, moderate-certainty evidence; 6MWD: MD 57 m, 95% CI 34 to 80 m, 5 studies, 182 participants, high-certainty evidence). One adverse event (hip fracture) related to the intervention was reported in one of the included studies. The intervention group also achieved greater improvements in the physical component of general HRQoL (MD 5.0 points, 95% CI 2.3 to 7.7 points, 4 studies, 208 participants, low-certainty evidence); improved force-generating capacity of the quadriceps muscle (SMD 0.75, 95% CI 0.4 to 1.1, 4 studies, 133 participants, moderate-certainty evidence); and less dyspnoea (SMD -0.43, 95% CI -0.81 to -0.05, 3 studies, 110 participants, very low-certainty evidence). We observed uncertain effects on the mental component of general HRQoL, disease-specific HRQoL, handgrip force, fatigue, and lung function. There were insufficient data to comment on the effect of exercise training on maximal inspiratory and expiratory pressures and feelings of anxiety and depression. Mortality was not reported in the included studies.
Authors' conclusions: Exercise training increased exercise capacity and quadriceps muscle force of people following lung resection for NSCLC. Our findings also suggest improvements on the physical component score of general HRQoL and decreased dyspnoea. This systematic review emphasises the importance of exercise training as part of the postoperative management of people with NSCLC.

Rapee RM, Shaw T, Hunt C, Bussey K, Hudson JL, Mihalopoulos C, Roberts C, Fitzpatrick S, Radom N, Cordin T, Epstein M, Cross D. (2020)MEDLINE-indexed journal, not yet read by usAggressive behavior · randomised controlled trial Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized, effectiveness trial.
Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated "real-world" implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.

Koehler VB, Rutherford MD. (2026)MEDLINE-indexed journal, not yet read by usEvolutionary psychology : an international journal of evolutionary approaches to psychology and behavior Harshness Predicts Reproduction in Brazilian Municipalities and US Counties: A Life History Theory Approach.
Psychosocial acceleration theory (PAT) posits that harsh and unpredictable ecologies during childhood can cue humans into developing earlier and more frequent reproduction. This study tested whether variables measuring harsh and unpredictable circumstances in 4,135 Brazilian municipalities and in 2,763 US counties would predict reproductive behavior 10 to 14 years later. Data was extracted from the Brazilian Census and American Community Survey samples. A secondary analysis explored whether the percentage of visible minorities (Black and Indigenous population) would also be a predictor or mediator of the same outcomes. Partial least squares structural equation modeling and multivariate linear regression were used in the analysis of Brazil and US data, respectively. Municipalities with higher rates of lack of resources, with young mothers both married or separated, and with large families with many residents per room were predictive of higher rates of teenage and young adult mothers and of young children in Brazil. Harshness predicted the percentage of young children in US counties, but the direction of this association was mixed. Some findings were contrary to PAT predictions. Divorce rates were negative predictors of reproduction in both countries. Education and employment indicators were not significant predictors of reproduction in Brazil. Higher rates of perceived minorities were not a relevant predictor in Brazil, and they were a negative predictor of the percentage of children in the United States. Findings suggest that harsh ecologies and the proportion of children in the population impact patterns of reproduction a decade later.

Novak I, Honan I. (2019)MEDLINE-indexed journal, not yet read by usAustralian occupational therapy journal · systematic review Effectiveness of paediatric occupational therapy for children with disabilities: A systematic review.
Introduction: Paediatric occupational therapy seeks to improve children's engagement and participation in life roles. A wide variety of intervention approaches exist. Our aim was to summarise the best-available intervention evidence for children with disabilities, to assist families and therapists choose effective care.
Methods: We conducted a systematic review (SR) using the Cochrane methodology, and reported findings according to PRISMA. CINAHL, Cochrane Library, MEDLINE, OTSeeker, PEDro, PsycINFO were searched. Two independent reviewers: (i) determined whether studies met inclusion: SR or randomised controlled trial (RCT); an occupational therapy intervention for children with a disability; (ii) categorised interventions based on name, core components and diagnostic population; (iii) rated quality of evidence and determined the strength of recommendation using GRADE criteria; and (iv) made recommendations using the Evidence Alert Traffic Light System.
Results: 129 articles met inclusion (n = 75 (58%) SRs; n = 54 (42%)) RCTs, measuring the effectiveness of 52 interventions, across 22 diagnoses, enabling analysis of 135 intervention indications. Thirty percent of the indications assessed (n = 40/135) were graded 'do it' (Green Go); 56% (75/135) 'probably do it' (Yellow Measure); 10% (n = 14/135) 'probably don't do it' (Yellow Measure); and 4% (n = 6/135) 'don't do it' (Red Stop). Green lights were: Behavioural Interventions; Bimanual; Coaching; Cognitive Cog-Fun & CAPS; CO-OP; CIMT; CIMT plus Bimanual; Context-Focused; Ditto; Early Intervention (ABA, Developmental Care); Family Centred Care; Feeding interventions; Goal Directed Training; Handwriting Task-Specific Practice; Home Programs; Joint Attention; Mental Health Interventions; occupational therapy after toxin; Kinesiotape; Pain Management; Parent Education; PECS; Positioning; Pressure Care; Social Skills Training; Treadmill Training and Weight Loss 'Mighty Moves'.
Conclusion: Evidence supports 40 intervention indications, with the greatest number at the activities-level of the International Classification of Function. Yellow light interventions should be accompanied by a sensitive outcome measure to monitor progress and red light interventions could be discontinued because effective alternatives existed.

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

Cognitive-behavioral therapy (CBT) versus acceptance and commitment therapy (ACT) for dementia family caregivers with significant depressive symptoms: Results of a randomized clinical trial.
Objective: The differential efficacy of acceptance and commitment therapy (ACT) and cognitive-behavioral therapy (CBT) for dementia family caregivers' is analyzed through a randomized controlled trial.
Method: Participants were 135 caregivers with high depressive symptomatology who were randomly allocated to the intervention conditions or a control group (CG). Pre-, postintervention, and follow-up measurements assessed depressive symptomatology, anxiety, leisure, dysfunctional thoughts, and experiential avoidance.
Results: Depression: Significant effects of interventions compared with CG were found for CBT (p < .001, d = 0.98, number needed to treat [NNT] = 3.61) and ACT (p < .001, d = 1.17, NNT = 3.53) at postintervention, but were maintained only at follow-up for CBT (p = .02, d = 0.74, NNT = 9.71). Clinically significant change was observed in 26.7% participants in CBT, 24.2% in ACT, and 0% in CG. At follow-up, 10.53% in CBT and 4% in ACT were recovered (0% CG). Anxiety: At postintervention, ACT participants showed lower anxiety than CBT participants (p < .05, d = 0.50) and CG participants (p < .01, d = 0.79, NNT = 3.86), with no effects at follow-up. At postintervention, 23.33% in CBT, 36.36% in ACT, and 6.45% in CG showed clinically significant change. At follow-up, 26.32% in CBT, 36% in ACT, and 13.64% in CG were recovered. Significant changes at postintervention were found in leisure and dysfunctional thoughts in both ACT and CBT, with changes in experiential avoidance only for ACT.
Conclusion: Similar results were obtained for ACT and CBT. ACT seems to be a viable and effective treatment for dementia caregivers.

(2022)MEDLINE-indexed journal, not yet read by usThe Lancet. Infectious diseases · randomised controlled trial Remdesivir plus standard of care versus standard of care alone for the treatment of patients admitted to hospital with COVID-19 (DisCoVeRy): a phase 3, randomised, controlled, open-label trial.
Background: The antiviral efficacy of remdesivir against SARS-CoV-2 is still controversial. We aimed to evaluate the clinical efficacy of remdesivir plus standard of care compared with standard of care alone in patients admitted to hospital with COVID-19, with indication of oxygen or ventilator support.
Methods: DisCoVeRy was a phase 3, open-label, adaptive, multicentre, randomised, controlled trial conducted in 48 sites in Europe (France, Belgium, Austria, Portugal, Luxembourg). Adult patients (aged ≥18 years) admitted to hospital with laboratory-confirmed SARS-CoV-2 infection and illness of any duration were eligible if they had clinical evidence of hypoxaemic pneumonia, or required oxygen supplementation. Exclusion criteria included elevated liver enzymes, severe chronic kidney disease, any contraindication to one of the studied treatments or their use in the 29 days before random assignment, or use of ribavirin, as well as pregnancy or breastfeeding. Participants were randomly assigned (1:1:1:1:1) to receive standard of care alone or in combination with remdesivir, lopinavir-ritonavir, lopinavir-ritonavir and interferon beta-1a, or hydroxychloroquine. Randomisation used computer-generated blocks of various sizes; it was stratified on severity of disease at inclusion and on European administrative region. Remdesivir was administered as 200 mg intravenous infusion on day 1, followed by once daily, 1-h infusions of 100 mg up to 9 days, for a total duration of 10 days. It could be stopped after 5 days if the participant was discharged. The primary outcome was the clinical status at day 15 measured by the WHO seven-point ordinal scale, assessed in the intention-to-treat population. Safety was assessed in the modified intention-to-treat population and was one of the secondary outcomes. This trial is registered with the European Clinical Trials Database, EudraCT2020-000936-23, and ClinicalTrials.gov, NCT04315948.
Findings: Between March 22, 2020, and Jan 21, 2021, 857 participants were enrolled and randomly assigned to remdesivir plus standard of care (n=429) or standard of care only (n=428). 15 participants were excluded from analysis in the remdesivir group, and ten in the control group. At day 15, the distribution of the WHO ordinal scale was: (1) not hospitalised, no limitations on activities (61 [15%] of 414 in the remdesivir group vs 73 [17%] of 418 in the control group); (2) not hospitalised, limitation on activities (129 [31%] vs 132 [32%]); (3) hospitalised, not requiring supplemental oxygen (50 [12%] vs 29 [7%]); (4) hospitalised, requiring supplemental oxygen (76 [18%] vs 67 [16%]); (5) hospitalised, on non-invasive ventilation or high flow oxygen devices (15 [4%] vs 14 [3%]); (6) hospitalised, on invasive mechanical ventilation or extracorporeal membrane oxygenation (62 [15%] vs 79 [19%]); (7) death (21 [5%] vs 24 [6%]). The difference between treatment groups was not significant (odds ratio 0·98 [95% CI 0·77-1·25]; p=0·85). There was no significant difference in the occurrence of serious adverse events between treatment groups (remdesivir, 135 [33%] of 406 vs control, 130 [31%] of 418; p=0·48). Three deaths (acute respiratory distress syndrome, bacterial infection, and hepatorenal syndrome) were considered related to remdesivir by the investigators, but only one by the sponsor's safety team (hepatorenal syndrome).
Interpretation: No clinical benefit was observed from the use of remdesivir in patients who were admitted to hospital for COVID-19, were symptomatic for more than 7 days, and required oxygen support.

Long-term effects of the family bereavement program on multiple indicators of grief in parentally bereaved children and adolescents.
Objectives: This article reports on results from a randomized experimental trial of the effects of the Family Bereavement Program (FBP) on multiple measures of grief experienced by parentally bereaved children and adolescents over a 6-year period.
Method: Participants were 244 youths (ages 8-16, mean age = 11.4 years) from 156 families that had experienced the death of a parent. The sample consisted of 53% boys and 47% girls; ethnicity was 67% non-Hispanic White and 33% ethnic minority. Families were randomly assigned to the FBP (N = 135) or a literature control condition (N = 109). Two grief measures, the Texas Revised Inventory of Grief and the Intrusive Grief Thoughts Scale (IGTS) were administered at 4 times over 6 years: pretest, posttest, and 11-month and 6-year follow-ups. A 3rd measure, an adaptation of the Inventory of Traumatic Grief (ITG) was administered only at the 6-year follow-up.
Results: Compared with the control group, the FBP group showed a greater reduction in their level of problematic grief (IGTS) at posttest and 6-year follow-up and in the percentage at clinical levels of problematic grief at the posttest. The FBP also reduced scores on a dimension of the ITG, Social Detachment/Insecurity, at 6-year follow-up for 3 subgroups: those who experienced lower levels of grief at program entry, older youths, and boys.
Conclusion: These are the first findings from a randomized trial with long-term follow-up of the effects of a program to reduce problematic levels of grief of parentally bereaved youths.

Effectiveness of internet-based cognitive behavioural treatment for adolescents with chronic fatigue syndrome (FITNET): a randomised controlled trial.
Background: Chronic fatigue syndrome is characterised by persistent fatigue and severe disability. Cognitive behavioural therapy seems to be a promising treatment, but its availability is restricted. We developed Fatigue In Teenagers on the interNET (FITNET), the first dedicated internet-based therapeutic program for adolescents with this disorder, and compared its effectiveness with that of usual care.
Methods: Adolescents aged 12-18 years with chronic fatigue syndrome were assigned to FITNET or usual care in a 1:1 ratio at one tertiary treatment centre in the Netherlands by use of a computer-generated blocked randomisation allocation schedule. The study was open label. Primary outcomes were school attendance, fatigue severity, and physical functioning, and were assessed at 6 months with computerised questionnaires. Analysis was by intention to treat. Thereafter, all patients were offered FITNET if needed. This trial is registered, number ISRCTN59878666.
Findings: 68 of 135 adolescents were assigned to FITNET and 67 to usual care, and 67 and 64, respectively, were analysed. FITNET was significantly more effective than was usual care for all dichotomised primary outcomes at 6 months-full school attendance (50 [75%] vs 10 [16%], relative risk 4·8, 95% CI 2·7-8·9; p<0·0001), absence of severe fatigue (57 [85%] vs 17 [27%], 3·2, 2·1-4·9; p<0·0001), and normal physical functioning (52 [78%] vs 13 [20%], 3·8, 2·3-6·3; p<0·0001). No serious adverse events were reported.
Interpretation: FITNET offers a readily accessible and highly effective treatment for adolescents with chronic fatigue syndrome. The results of this study justify implementation on a broader scale.

Multiple sclerosis and extract of cannabis: results of the MUSEC trial.
Objective: Multiple sclerosis (MS) is associated with chronic symptoms, including muscle stiffness, spasms, pain and insomnia. Here we report the results of the Multiple Sclerosis and Extract of Cannabis (MUSEC) study that aimed to substantiate the patient based findings of previous studies.
Patients and methods: Patients with stable MS at 22 UK centres were randomised to oral cannabis extract (CE) (N=144) or placebo (N=135), stratified by centre, walking ability and use of antispastic medication. This double blind, placebo controlled, phase III study had a screening period, a 2 week dose titration phase from 5 mg to a maximum of 25 mg of tetrahydrocannabinol daily and a 10 week maintenance phase. The primary outcome measure was a category rating scale (CRS) measuring patient reported change in muscle stiffness from baseline. Further CRSs assessed body pain, spasms and sleep quality. Three validated MS specific patient reported outcome measures assessed aspects of spasticity, physical and psychological impact, and walking ability.
Results: The rate of relief from muscle stiffness after 12 weeks was almost twice as high with CE than with placebo (29.4% vs. 15.7%; OR 2.26; 95% CI 1.24 to 4.13; p=0.004, one sided). Similar results were found after 4 weeks and 8 weeks, and also for all further CRSs. Results from the MS scales supported these findings.
Conclusion: The study met its primary objective to demonstrate the superiority of CE over placebo in the treatment of muscle stiffness in MS. This was supported by results for secondary efficacy variables. Adverse events in participants treated with CE were consistent with the known side effects of cannabinoids. No new safety concerns were observed.

Gender perspective on quality of life, comparisons between groups 4-5.5 years after unsuccessful or successful IVF treatment.
Objective: To describe and compare quality of life in men and women who had in vitro fertilization (IVF) within the Swedish public health system 4-5.5 years previously, either unsuccessfully and were subsequently living without children, or successfully, having children aged 4-5.5 years. These groups were compared to a control group of men and women with children born at the same time as in the successful group.
Design: Cross-sectional study.
Setting: Reproductive Unit, Sahlgrenska University Hospital, Gothenburg, Sweden.
Sample: Twenty-six men and 37 women in the unsuccessful group, 135 men and 154 women in the successful group and 93 men and 118 women in the control group.
Methods: Questionnaire study. The respective gender differences were studied in the control and study groups.
Main outcome measures: Psychological general well-being (PGWB), sense of coherence (SOC), experience of infertility, demographic-socio-economic, and health characteristics.
Results: Men in the unsuccessful IVF group scored lower in total PGWB and SOC indices than the successful group men. They reported more depression, lower PGWB and lower SOC than the control group men. Women in the unsuccessful IVF group reported more anxiety, depression, and lower SOC than the successful group women and more depression and lower SOC indices than control group women. Men and women in the unsuccessful IVF group did not differ in any of the parameters. Men in the successful IVF group had higher PGWB, less signs of depression and more self-confidence than women in that group.

Development and validation of the Body and Appearance Self-Conscious Emotions Scale (BASES).
The purpose of these studies was to develop a psychometrically sound measure of shame, guilt, authentic pride, and hubristic pride for use in body and appearance contexts. In Study 1, 41 potential items were developed and assessed for item quality and comprehension. In Study 2, a panel of experts (N=8; M=11, SD=6.5 years of experience) reviewed the scale and items for evidence of content validity. Participants in Study 3 (n=135 males, n=300 females) completed the BASES and various body image, personality, and emotion scales. A separate sample (n=155; 35.5% male) in Study 3 completed the BASES twice using a two-week time interval. The BASES subscale scores demonstrated evidence for internal consistency, item-total correlations, concurrent, convergent, incremental, and discriminant validity, and 2-week test-retest reliability. The 4-factor solution was a good fit in confirmatory factor analysis, reflecting body-related shame, guilt, authentic and hubristic pride subscales of the BASES. The development and validation of the BASES may help advance body image and self-conscious emotion research by providing a foundation to examine the unique antecedents and outcomes of these specific emotional experiences.

(2021)MEDLINE-indexed journal, not yet read by usJMIR aging · review Impact of the COVID-19 Pandemic on Older Adults: Rapid Review.
Background: The COVID-19 pandemic has drastically changed the lives of countless members of the general population. Older adults are known to experience loneliness, age discrimination, and excessive worry. It is therefore reasonable to anticipate that they would experience greater negative outcomes related to the COVID-19 pandemic given their increased isolation and risk for complications than younger adults.
Objective: This study aims to synthesize the existing research on the impact of the COVID-19 pandemic, and associated isolation and protective measures, on older adults. The secondary objective is to investigate the impact of the COVID-19 pandemic, and associated isolation and protective measures, on older adults with Alzheimer disease and related dementias.
Methods: A rapid review of the published literature was conducted on October 6, 2020, through a search of 6 online databases to synthesize results from published original studies regarding the impact of the COVID-19 pandemic on older adults. The Human Development Model conceptual framework-Disability Creation Process was used to describe and understand interactions between personal factors, environmental factors, and life habits. Methods and results are reported following the Preferred Reporting Items for Systematic Reviews and Meta-analyses Statement.
Results: A total of 135 records were included from the initial search strategy of 13,452 individual studies. Of these, 113 (83.7%) studies were determined to be of level 4 according to the levels of evidence classification by the Centre for Evidence-Based Medicine. The presence of psychological symptoms, exacerbation of ageism, and physical deterioration of aged populations were reported in the included studies. Decreased social life and fewer in-person social interactions reported during the COVID-19 pandemic were occasionally associated with reduced quality of life and increased depression. Difficulties accessing services, sleep disturbances, and a reduction of physical activity were also noted.
Conclusions: Our results highlight the need for adequate isolation and protective measures. Older adults represent a heterogeneous group, which could explain the contradictory results found in the literature. Individual, organizational, and institutional strategies should be established to ensure that older adults are able to maintain social contacts, preserve family ties, and maintain the ability to give or receive help during the current pandemic. Future studies should focus on specific consequences and needs of more at-risk older adults to ensure their inclusion, both in public health recommendations and considerations made by policy makers.

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

Patients with asthma have an underlying chronic inflammation of the airways characterized by activated mast cells, eosinophils, and T-helper 2 lymphocytes. This results in increased responsiveness of the airways to such triggers as exercise, allergens, and air pollutants. This chronic inflammation underlies the typical symptoms of asthma, which include intermittent wheezing, coughing, shortness of breath, and chest tightness. Corticosteroids are the most effective treatment for asthma, and inhaled corticosteroids have become first-line treatment for children and adults with persistent symptoms.

Social connection and mortality in UK Biobank: a prospective cohort analysis.
Background: Components of social connection are associated with mortality, but research examining their independent and combined effects in the same dataset is lacking. This study aimed to examine the independent and combined associations between functional and structural components of social connection and mortality.
Methods: Analysis of 458,146 participants with full data from the UK Biobank cohort linked to mortality registers. Social connection was assessed using two functional (frequency of ability to confide in someone close and often feeling lonely) and three structural (frequency of friends/family visits, weekly group activities, and living alone) component measures. Cox proportional hazard models were used to examine the associations with all-cause and cardiovascular disease (CVD) mortality.
Results: Over a median of 12.6 years (IQR 11.9-13.3) follow-up, 33,135 (7.2%) participants died, including 5112 (1.1%) CVD deaths. All social connection measures were independently associated with both outcomes. Friends/family visit frequencies < monthly were associated with a higher risk of mortality indicating a threshold effect. There were interactions between living alone and friends/family visits and between living alone and weekly group activity. For example, compared with daily friends/family visits-not living alone, there was higher all-cause mortality for daily visits-living alone (HR 1.19 [95% CI 1.12-1.26]), for never having visits-not living alone (1.33 [1.22-1.46]), and for never having visits-living alone (1.77 [1.61-1.95]). Never having friends/family visits whilst living alone potentially counteracted benefits from other components as mortality risks were highest for those reporting both never having visits and living alone regardless of weekly group activity or functional components. When all measures were combined into overall functional and structural components, there was an interaction between components: compared with participants defined as not isolated by both components, those considered isolated by both components had higher CVD mortality (HR 1.63 [1.51-1.76]) than each component alone (functional isolation 1.17 [1.06-1.29]; structural isolation 1.27 [1.18-1.36]).
Conclusions: This work suggests (1) a potential threshold effect for friends/family visits, (2) that those who live alone with additional concurrent markers of structural isolation may represent a high-risk population, (3) that beneficial associations for some types of social connection might not be felt when other types of social connection are absent, and (4) considering both functional and structural components of social connection may help to identify the most isolated in society.

The vascular response to acute sauna heating is similar in young and middle-aged adults.
Sauna has been linked to a reduction of cardiovascular disease risk and is a promising nonpharmacological treatment for populations at risk of cardiovascular disease. This study examined the vascular response to an acute bout of sauna heating in young and middle-aged individuals. Ten young (25 ± 4 yr, 6 males and 4 females) and eight middle-aged adults (56 ± 4 yr, 4 males and 4 females) underwent 40 min of sauna exposure at 80°C. Esophageal and intramuscular temperatures, brachial and superficial femoral artery blood flow, artery diameter, and shear rates were recorded at baseline and following heat exposure. Brachial artery flow-mediated dilation (FMD) was measured at baseline and following 90 min of recovery. Esophageal and muscle temperatures increased similarly in the young and middle-aged adults by 1.5 ± 0.53 and 1.95 ± 0.70°C, respectively (P < 0.05). The shear rate increased by 170-200% (P < 0.001), while blood flow increased by 180-390% (P < 0.001) in the superficial femoral and brachial arteries, respectively, and did not differ between age groups (P = 0.190-0.899). Systolic blood pressure was reduced from 135 ± 17 to 122 ± 20 mmHg (P = 0.017) in middle-aged participants. These data indicate that young and middle-aged adults have similar vascular responses to acute sauna heating.NEW & NOTEWORTHY Sauna therapy has been shown to improve cardiovascular health and function in older adults and individuals with cardiovascular disease risk factors. Specifically, improvements in vascular function have been reported and have been attributed to the increased hemodynamic stimuli on the vasculature associated with thermal stress. The present study quantified this hemodynamic response to a sauna protocol associated with improved cardiovascular health across the lifespan. Our data show that middle-aged adults have the same shear rate and blood flow response to sauna as young adults.
