RESUMEN
Public health interventions implemented during the COVID-19 pandemic may exacerbate anxiety symptoms for many. We conducted this study to better understand the role of leisure activity in promoting mental wellness during times of social isolation and reduced access to recreation facilities and mental health support services. We analyzed nationally representative survey data collected by Statistics Canada as part of the Canadian Perspectives Survey Series (CPSS) during May 4-10 (CPSS 2) and July 20 to 26, 2020 (CPSS 4). Data related to leisure activity and anxiety symptoms as measured by a score of more than 10 on the General Anxiety Disorder scale were examined using descriptive and log-binomial regression analyses. Survey sampling weights were applied in all analyses, and regression results were adjusted for sociodemographic characteristics. Exercise and communication with friends and loved ones were the most frequently reported leisure activity. Prevalence of moderate to severe anxiety symptoms reported by participants was lower in CPSS 4 compared to CPSS 2. Results of adjusted log-binomial regression analyses revealed lower prevalence of moderate to severe anxiety symptoms in those who engaged in exercise and communication, while those who meditated exhibited higher prevalence. In conclusion, leisure activities, such as exercise and communication with loved ones, can promote mental wellness. Future research should clarify the role of meditation for mental wellness promotion during periods of social isolation.

Introduction: Clozapine is the most effective antipsychotic in the management of treatment-resistant schizophrenia; however, its use is challenging due to the risk of severe adverse effects. Despite the risks associated with clozapine, there is no mandatory monitoring in Canada beyond hematologic testing for agranulocytosis surveillance. This study focuses on the development, implementation, and evaluation of a clozapine clinical toolkit (CTK) targeted at optimizing inpatient clozapine use. Methods: A comprehensive literature review was conducted to identify clozapine best practices, experts were consulted, and a comprehensive clozapine CTK was developed and implemented at a large Canadian tertiary hospital in December 2018. To evaluate the CTK, a retrospective chart review was conducted to assess for change in guideline-concordant monitoring pre- and post- CTK implementation. Patients were included if they were > 18 years of age and received clozapine during inpatient admission. Results were analyzed using descriptive and inferential statistics. Results: Among the charts reviewed, 185 and 113 admissions met the pre- and post-CTK inclusion criteria, respectively. Staff used the CTK in the care of 96% of clozapine patients post implementation, and its use resulted in improvements in guideline-concordant monitoring for agranulocytosis and myocarditis. Discussion: Implementation of the clozapine CTK increased the concordance of clozapine monitoring with best practice recommendations. Future research is necessary to assess the impact of the CTK on clinical outcomes and patient satisfaction.
RESUMEN
AIM: Prehabilitation for colorectal cancer has focused on exercise-based interventions that are typically designed by clinicians; however, no research has yet been patient-oriented. The aim of this feasibility study was to test a web-based multimodal prehabilitation intervention (known as PREP prehab) consisting of four components (physical activity, diet, smoking cessation, psychological support) co-designed with five patient partners. METHOD: A longitudinal, two-armed (website without or with coaching support) feasibility study of 33 patients scheduled for colorectal surgery 2 weeks or more from consent (January-September 2021) in the province of British Columbia, Canada. Descriptive statistics analysed a health-related quality of life questionnaire (EQ5D-5L) at baseline (n = 25) and 3 months postsurgery (n = 21), and a follow-up patient satisfaction survey to determine the acceptability, practicality, demand for and potential efficacy in improving overall health. RESULTS: Patients had a mean age of 52 years (SD 14 years), 52% were female and they had a mean body mass index of 25 kg m-2 (SD 3.8 kg m-2). Only six patients received a Subjective Global Assessment for being at risk for malnutrition, with three classified as 'severely/moderately' malnourished. The majority (86%) of patients intended to use the prehabilitation website, and nearly three-quarters (71%) visited the website while waiting for surgery. The majority (76%) reported that information, tools and resources provided appropriate support, and 76% indicated they would recommend the PREP prehab programme. About three-quarters (76%) reported setting goals for lifestyle modification: 86% set healthy eating goals, 81% aimed to stay active and 57% sought to reduce stress once a week or more. No patients contacted the team to obtain health coaching, despite broad interest (71%) in receiving active support and 14% reporting they received 'active support'. CONCLUSION: This web-based multimodal prehabilitation programme was acceptable, practical and well-received by all colorectal surgery patients who viewed the patient-oriented multimodal website. The feasibility of providing active health coaching support requires further investigation.

OBJECTIVE: The study objective was to describe patterns of depression and anxiety health care use before and after diagnosis among patients with inflammatory arthritis (IA), namely, ankylosing spondylitis, psoriatic arthritis, and rheumatoid arthritis. METHODS: We used population-based linked administrative health data from British Columbia, Canada, to build a cohort of individuals (≥18 years) with incident IA and individuals without IA ("IA-free controls") matched on age and sex. We computed the proportion of individuals with IA and controls who had one or more depression or one or more anxiety health care encounters and the use of one or more antidepressants or one or more anxiolytics in each yearly interval five years before and after IA diagnosis. We used multivariable logistic regression models to evaluate the association between IA status and aforementioned depression and anxiety health care use outcomes in each yearly interval. RESULTS: A total of 80,238 individuals with IA (62.9% female; mean ± SD age 56.2 ± 16.7 years) and 80,238 IA-free controls (62.9% female; mean ± SD age 56.2 ± 16.6 years) were identified between January 1, 2001, and March 31, 2018. Individuals with IA had significantly increased odds of depression and anxiety health care encounters and dispensation of antidepressants and anxiolytics for each yearly interval before and after diagnosis. Adjusted odds ratios (ORs) were highest in the year immediately before (one or more depression visits: adjusted OR 1.61, 95% confidence interval [CI] 1.55-1.66; one or more anxiolytics: adjusted OR 1.71, 95% CI 1.66-1.77) or after (one or more antidepressants: adjusted OR 1.95, 95% CI 1.89-2.00) IA diagnosis. CONCLUSION: Findings suggest a role for depression and anxiety in characterizing the IA prodrome period and generate hypotheses regarding overlapping biopsychosocial processes that link IA and mental health comorbidities.
RESUMEN
BACKGROUND: The rising trend of providing palliative care to residents in Canadian long-term care facilities places additional demands on care staff, increasing their risk of burnout. Interventions and strategies to alleviate burnout are needed to reduce its impact on quality of patient care and overall functioning of healthcare organizations. AIM: To examine the feasibility of implementing online modules with the primary goal of determining recruitment and retention rates, completion time and satisfaction with the modules. A secondary goal was to describe changes in burnout and related symptoms associated with completing the modules. SETTING: This single-arm, nonrandomized feasibility study was conducted in five long-term care sites of a publicly-funded healthcare organization in Vancouver, British Columbia, Canada. Eligible participants were clinical staff who worked at least 1 day per month. RESULTS: A total of 103 study participants consented to participate, 31 (30.1%) of whom were lost to follow-up. Of the remaining 72 participants, 64 (88.9%) completed the modules and all questionnaires. Most participants completed the modules in an hour (89%) and found them easy to understand (98%), engaging (84%), and useful (89%). Mean scores on burnout and secondary traumatic stress decreased by .9 (95% CI: .1-1.8; d = .3) and 1.4 (95% CI: .4-2.4; d = .4), respectively; mean scores on compassion satisfaction were virtually unchanged. CONCLUSIONS: Modules that teach strategies to reduce burnout among staff in long-term care are feasible to deliver and have the potential to reduce burnout and related symptoms. Randomized controlled trials are needed to assess effectiveness and longer-term impact.

Objectives: Poverty exposes children to adverse conditions that negatively impact development. However, there is limited understanding on how different types of poverty may affect children of various immigration backgrounds differently in outcomes such as school readiness. This study examined these relationships between household and/or neighbourhood poverty, poverty timing, and immigration background with school readiness outcomes at kindergarten. Methods: This study utilized a retrospective, population-based cohort of administrative records linked with surveys completed by kindergarten teachers for 15 369 children born in British Columbia, Canada. The exposures investigated were neighbourhood poverty (residing in a neighbourhood in the lowest income-quintile) and/or household poverty (receiving a health insurance subsidy due to low household income). Experiencing both neighbourhood and household poverty simultaneously was defined as "combined" household and neighbourhood poverty. The outcome of vulnerability on school readiness domains was assessed at kindergarten (47.8% female; mean age = 6.01 years) using teacher ratings on the Early Development Instrument (EDI). Results: Children exposed to combined poverty between age 0 and 2 had greater odds of being vulnerable in two or more domains of school readiness than children not exposed to any poverty during this period (adjusted odds ratio (aOR) = 2.07, 95% CI: [1.74; 2.47], p < 0.001). The effect of combined poverty was larger than household poverty only (aOR = 1.54, 95% CI: [1.31; 1.82], p < 0.001) or neighbourhood poverty only (aOR = 1.49, 95% CI: [1.30; 1.70], p < 0.001). Combined poverty was associated with negative outcomes regardless of timing. Both non-immigrants (aOR = 2.40, 95% CI: [1.92; 3.00], p < 0.001) and second-generation immigrants (aOR = 1.63, 95% CI: [1.22; 2.17], p < 0.001) experiencing combined poverty scored lower on school readiness. Conclusions: Children who experienced combined poverty had lower levels of school readiness at kindergarten, regardless of timing and immigration background.
RESUMEN
INTRODUCTION: People living with HIV (PLWH) and/or who inject drugs may experience lower vaccine effectiveness (VE) against SARS-CoV-2 infection. METHODS: A validated algorithm was applied to population-based, linked administrative datasets in the British Columbia COVID-19 Cohort (BCC19C) to ascertain HIV status and create a population of PLWH and matched HIV-negative individuals. The study population was limited to individuals who received an RT-PCR laboratory test for SARS-CoV-2 between 15 December 2020 and 21 November 2021 in BC, Canada. Any history of injection drug use (IDU) was ascertained using a validated administrative algorithm. We used a test-negative study design (modified case-control analysis) and multivariable logistic regression to estimate adjusted VE by HIV status and history of IDU. RESULTS: Our analysis included 2700 PLWH and a matched population of 375,043 HIV-negative individuals, among whom there were 351 and 103,049 SARS-CoV-2 cases, respectively. The proportion of people with IDU history was much higher among PLWH compared to HIV-negative individuals (40.7% vs. 4.3%). Overall VE during the first 6 months after second dose was lower among PLWH with IDU history (65.8%, 95% CI = 43.5-79.3) than PLWH with no IDU history (80.3%, 95% CI = 62.7-89.6), and VE was particularly low at 4-6 months (42.4%, 95% CI = -17.8 to 71.8 with IDU history vs. 64.0%; 95% CI = 15.7-84.7 without), although confidence intervals were wide. In contrast, overall VE was 88.6% (95% CI = 88.2-89.0) in the matched HIV-negative population with no history of IDU and remained relatively high at 4-6 months after second dose (84.6%, 95% CI = 83.8-85.4). Despite different patterns of vaccine protection by HIV status and IDU history, peak estimates were similar (≥88%) across all populations. CONCLUSIONS: PLWH with a history of IDU may experience lower VE against COVID-19 infection, although findings were limited by a small sample size. The lower VE at 4-6 months may have implications for booster dose prioritization for PLWH and people who inject drugs. The immunocompromising effect of HIV, substance use and/or co-occurring comorbidities may partly explain these findings.

BACKGROUND: Biosensor technologies have been proposed as a solution to provide recognition and facilitate earlier responses to unwitnessed out-of-hospital cardiac arrest (OHCA) cases. We sought to estimate the effect of recognition on survival and modelled the potential incremental impact of increased recognition of unwitnessed cases on survival to hospital discharge, to demonstrate the potential benefit of biosensor technologies. METHODS: We included cases from the British Columbia Cardiac Arrest Registry (2019-2020), which includes Emergency Medical Services (EMS)-assessed OHCAs. We excluded cases that would not have benefitted from early recognition (EMS-witnessed, terminal illness, or do-not-resuscitate). Using a mediation analysis, we estimated the relative benefits on survival of a witness recognizing vs. intervening in an OHCA; and estimated the expected additional number of survivors resulting from increasing recognition alone using a bootstrap logistic regression framework. RESULTS: Of 13,655 EMS-assessed cases, 11,412 were included (6314 EMS-treated, 5098 EMS-untreated). Survival to hospital discharge was 191/8879 (2.2%) in unwitnessed cases and 429/2533 (17%) in bystander-witnessed cases. Of the total effect attributable to a bystander witness, recognition accounted for 84% (95% CI: 72, 86) of the benefit. If all previously unwitnessed cases had been bystander witnessed, we would expect 1198 additional survivors. If these cases had been recognized, but no interventions performed, we would expect 912 additional survivors. CONCLUSION: Unwitnessed OHCA account for the majority of OHCAs, yet survival is dismal. Methods to improve recognition, such as with biosensor technologies, may lead to substantial improvements in overall survival.

OBJECTIVE: To examine the risk of hospitalization within 14 days of COVID-19 diagnosis among people living with HIV (PLWH) and HIV-negative individuals who had laboratory-confirmed SARS-CoV-2 infection. METHODS: We used Cox proportional hazard models to compare the relative risk of hospitalization in PLWH and HIV-negative individuals. Then, we used propensity score weighting to examine the influence of sociodemographic factors and comorbid conditions on risk of hospitalization. These models were further stratified by vaccination status and pandemic period (pre-Omicron: December 15, 2020, to November 21, 2021; Omicron: November 22, 2021, to October 31, 2022). RESULTS: The crude hazard ratio (HR) for risk of hospitalization in PLWH was 2.44 (95% confidence interval [CI]: 2.04-2.94). In propensity score-weighted models that included all covariates, the relative risk of hospitalization was substantially attenuated in the overall analyses (adjusted HR [aHR]: 1.03; 95% CI: 0.85-1.25), in vaccinated (aHR 1.00; 95% CI: 0.69-1.45), inadequately vaccinated (aHR: 1.04; 95% CI: 0.76-1.41) and unvaccinated individuals (aHR: 1.15; 95% CI: 0.84-1.56). CONCLUSION: PLWH had about two times the risk of COVID-19 hospitalization than HIV-negative individuals in crude analyses which attenuated in propensity score-weighted models. This suggests that the risk differential can be explained by sociodemographic factors and history of comorbidity, underscoring the need to address social and comorbid vulnerabilities (e.g., injecting drugs) that were more prominent among PLWH.
RESUMEN
Objectives: Dyspnoea is a common persistent symptom post-coronavirus disease 2019 (COVID-19) illness. However, the mechanisms underlying dyspnoea in the post-COVID-19 syndrome remain unclear. The aim of our study was to examine dyspnoea quality and intensity, burden of mental health symptoms, and differences in exercise responses in people with and without persistent dyspnoea following COVID-19. Methods: 49 participants with mild-to-critical COVID-19 were included in this cross-sectional study 4â months after acute illness. Between-group comparisons were made in those with and without persistent dyspnoea (defined as modified Medical Research Council dyspnoea score ≥1). Participants completed standardised dyspnoea and mental health symptom questionnaires, pulmonary function tests, and incremental cardiopulmonary exercise testing. Results: Exertional dyspnoea intensity and unpleasantness were increased in the dyspnoea group. The dyspnoea group described dyspnoea qualities of suffocating and tightness at peak exercise (p<0.05). Ventilatory equivalent for carbon dioxide (V'E/V'CO2) nadir was higher (32±5 versus 28±3, p<0.001) and anaerobic threshold was lower (41±12 versus 49±11% predicted maximum oxygen uptake, p=0.04) in the dyspnoea group, indicating ventilatory inefficiency and deconditioning in this group. The dyspnoea group experienced greater symptoms of anxiety, depression and post-traumatic stress (all p<0.05). A subset of participants demonstrated gas-exchange and breathing pattern abnormalities suggestive of dysfunctional breathing. Conclusions: People with persistent dyspnoea following COVID-19 experience a specific dyspnoea quality phenotype. Dyspnoea post-COVID-19 is related to abnormal pulmonary gas exchange and deconditioning and is linked to increased symptoms of anxiety, depression and post-traumatic stress.
RESUMEN
OBJECTIVE: The study objective was to assess mental and social health outcomes for individuals with rheumatic disease during the COVID-19 pandemic and evaluate the relationship of loneliness and social isolation with depression and anxiety. METHODS: We administered an international cross-sectional online survey to individuals with rheumatic disease(s) (≥18 years) between April 2020 and September 2020, with a follow-up survey from December 2020 to February 2021. We used questionnaires to evaluate loneliness (3-item UCLA Loneliness Scale [UCLA-3]), social isolation (Lubben Social Network Scale [LSNS-6]), depression (Patient Health Questionnaire [PHQ-9]), and anxiety (Generalized Anxiety Disorder 7-item [GAD-7] Scale). We used multivariable linear regression models to evaluate the cross-sectional associations of loneliness and social isolation with depression and anxiety at baseline. RESULTS: Seven hundred eighteen individuals (91.4% women, mean age: 45.4 ± 14.2 years) participated in the baseline survey, and 344 completed the follow-up survey. Overall, 51.1% of participants experienced loneliness (UCLA-3 score ≥6) and 30.3% experienced social isolation (LSNS-6 score <12) at baseline. Depression (PHQ-9 score ≥10) and anxiety (GAD-7 score ≥10) were experienced by 42.8% and 34.0% of participants at baseline, respectively. Multivariable models showed that experiencing both loneliness and social isolation, in comparison to experiencing neither, was significantly associated with an average 7.27 higher depression score (ß = 7.27; 95% confidence interval [CI]: 6.08-8.47) and 5.14 higher anxiety score (ß = 5.14; 95% CI: 4.00-6.28). CONCLUSION: Aside from showing substantial experience of loneliness and social isolation during the COVID-19 pandemic, our survey showed significant associations with depression and anxiety. Patient supports to address social health have potential implications for also supporting mental health.
RESUMEN
After a bout of isolated inspiratory work, such as inspiratory pressure threshold loading (IPTL), the human diaphragm can exhibit a reversible loss in contractile function, as evidenced by a decrease in transdiaphragmatic twitch pressure (PDI,TW ). Whether or not diaphragm fatigability after IPTL is affected by neural mechanisms, measured through voluntary activation of the diaphragm (D-VA) in addition to contractile mechanisms, is unknown. It is also unknown if changes in D-VA are similar between sexes given observed differences in diaphragm fatigability between males and females. We sought to determine whether D-VA decreases after IPTL and whether this was different between sexes. Healthy females (n = 11) and males (n = 10) completed an IPTL task with an inspired duty cycle of 0.7 and targeting an intensity of 60% maximal transdiaphragmatic pressure until task failure. PDI,TW and D-VA were measured using cervical magnetic stimulation of the phrenic nerves in combination with maximal inspiratory pressure maneuvers. At task failure, PDI,TW decreased to a lesser degree in females vs. males (87 ± 15 vs. 73 ± 12% baseline, respectively, p = 0.016). D-VA decreased after IPTL but was not different between females and males (91 ± 8 vs. 88 ± 10% baseline, respectively, p = 0.432). When all participants were pooled together, the decrease in PDI,TW correlated with both the total cumulative diaphragm pressure generation (R2 = 0.43; p = 0.021) and the time to task failure (TTF, R2 = 0.40; p = 0.30) whereas the decrease in D-VA correlated only with TTF (R2 = 0.24; p = 0.041). Our results suggest that neural mechanisms can contribute to diaphragm fatigability, and this contribution is similar between females and males following IPTL.

OBJECTIVES: We estimated the effectiveness of COVID-19 vaccines against laboratory-confirmed SARS-CoV-2 infection among people living with HIV (PLWH) and compared the estimates with a matched HIV-negative cohort. METHODS: We used the British Columbia COVID-19 Cohort, a population-based data platform, which integrates COVID-19 data on SARS-CoV-2 tests, laboratory-confirmed cases, and immunizations with provincial health services data. The vaccine effectiveness (VE) was estimated with a test-negative design using the multivariable logistic regression. RESULTS: The adjusted VE against SARS-CoV-2 infection was 71.1% (39.7, 86.1%) 7-59 days after two doses, rising to 89.3% (72.2, 95.9%) between 60 and 89 days. VE was preserved 4-6 months after the receipt of two doses, after which noticeable waning was observed (51.3% [4.8, 75.0%]). In the matched HIV-negative cohort (n = 375,043), VE peaked at 91.4% (90.9, 91.8%) 7-59 days after two doses and was sustained for up to 4 months, after which evidence of waning was observed, dropping to 84.2% (83.4, 85.0%) between 4 and 6 months. CONCLUSION: The receipt of two COVID-19 vaccine doses was effective against SARS-CoV-2 infection among PLWH pre-Omicron. VE estimates appeared to peak later in PLWH than in the matched HIV-negative cohort and the degree of waning was relatively quicker in PLWH; however, peak estimates were comparable in both populations.

PURPOSE: Evidence from systematic reviews suggests that adult immigrants living in areas of higher immigrant density (areas with a higher proportion of foreign-born residents) tend to experience fewer mental health problems-likely through less discrimination, greater access to culturally/linguistically appropriate services, and greater social support. Less is known about how such contexts are associated with mental health during childhood-a key period in the onset and development of many mental health challenges. This study examined associations between neighbourhood immigrant density and youth mental health conditions in British Columbia (BC; Canada). METHODS: Census-derived neighbourhood characteristics were linked to medical records for youth present in ten of BC's largest school districts from age 5 through 19 over the study period (1995-2016; n = 138,090). Occurrence of physician assessed diagnoses of mood and/or anxiety disorders, attention deficit hyperactivity disorder (ADHD), and conduct disorder was inferred through International Classification of Diseases (ICD) diagnostic codes in universal public health insurance records. Multi-level logistic regression was used to model associations between neighbourhood characteristics and odds of diagnoses for each condition; models were stratified by generation status (first-generation: foreign-born; second-generation: Canadian-born to a foreign-born parent; non-immigrant). RESULTS: Higher neighbourhood immigrant density was associated with lower odds of disorders among first-generation immigrant youth (e.g., adjusted odds of mood-anxiety disorders for those in neighbourhoods with the highest immigrant density were 0.67 times lower (95% CI: 0.49, 0.92) than those in neighbourhoods with the lowest immigrant density). Such protective associations generally extended to second-generation and non-immigrant youth, but were-for some disorders-stronger for first-generation than second-generation or non-immigrant youth. CONCLUSIONS: Findings suggest there may be protective mechanisms associated with higher neighbourhood immigrant density for mental health conditions in immigrant and non-immigrant youth. It is important that future work examines potential pathways by which contextual factors impact immigrant and non-immigrant youth mental health.

OBJECTIVE: We recently found that the risk of diagnosed non-affective psychotic disorder between the ages of 13 and 19 was lower for immigrant adolescents compared to those without a personal or parental migration history in British Columbia (BC), Canada. In the current study, we further examined the risk for migrants compared to non-migrants by region of origin and immigrant generation (first vs. second), adjusting for several demographic factors and migration class. METHODS: Administrative data were used to construct a cohort of individuals born 1990-98 and residing in South-Western BC (N = 193,400). Cases were identified by either one hospitalization or two outpatient physician visits with a primary diagnosis of a non-affective psychotic disorder. Poisson regression was used to estimate incidence rate ratios (IRR) of a diagnosed non-affective psychotic disorder by region of origin among first- and second-generation migrants compared to non-migrants, adjusting for sex, birth year, neighbourhood income and low family income. RESULTS: Risk of diagnosed non-affective psychotic disorder was lower among first-generation migrants from East Asia (IRR = 0.34[95% CI: 0.25-0.46]), South-Asia (IRR = 0.47[95% CI: 0.25-0.89]) and South-East Asia (IRR = 0.55[95% CI: 0.32-0.93]) and second-generation migrants from East Asia (IRR = 0.49[95% CI: 0.35-0.69]) and South Asia (IRR = 0.52[95% CI: 0.37-0.73]), compared to non-migrants. Adjusting for migration class attenuated but did not fully explain variation in risk by region among first-generation migrants. No groups exhibited a significantly elevated risk of the diagnosed non-affective psychotic disorder compared to non-migrants. CONCLUSION: Findings from this study underline the complexity of the association between migration and psychotic disorders. Future research should investigate why certain groups of migrants are less likely to be diagnosed and whether there are specific sub-groups that face an elevated risk.

INTRODUCTION: Mental disorders affect about 13% of the world's population. While evidence-based mental health treatments are available, a significant number of persons with mental illnesses are untreated or do not receive adequate mental healthcare due to various reasons, including costs, stigma and the desire to self-manage symptoms. In the past few years, there has been an increase in the body of evidence regarding leisure activities and mental wellness. However, there is currently no published overview of the state of the evidence on these activities and their potential preventive and therapeutic effects on mental health. METHODS AND ANALYSIS: Using Joanna Briggs Institute (JBI) review guidelines, an umbrella review will be undertaken to synthesise findings from systematic reviews and meta-analyses on the mental health benefits of home-based and community-based activities. MEDLINE, PsycInfo, Embase, CINAHL, Web of Science, Epistemonikos, Cochrane Database of Systematic Reviews, JBI Database of Systematic Reviews and Implementation Reports will be searched for potentially relevant systematic reviews and meta-analyses published from January 1991 to present. Title/abstract screening, full-text review, data extraction and assessment of methodological quality will each be performed independently by two reviewers. A third review author will be available to resolve discrepancies in any of the review tasks. To assess the quality of potentially eligible reviews, the JBI Critical Appraisal Checklist for Systematic Reviews and Research Syntheses will be used. Findings will be presented in table form and will be summarised by study population, type of home-based or community-based activity or intervention, and type of mental health outcomes. Overall assessment of the strength of existing evidence from eligible systematic reviews will be provided following the grading of recommendation, assessment, development and evaluation approach. ETHICS AND DISSEMINATION: No ethical approval is required. Results of this umbrella review will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42021266989.

BACKGROUND: South Asian immigrants in western countries are at a high risk for metabolic syndrome and associated chronic disease. While a physically active lifestyle is crucial in decreasing this risk, physical activity (PA) levels among this group remain low. The objectives of this study were to explore social and cultural factors that influence PA behavior, investigate how immigration process intersects with PA behaviors to influence PA levels and to engage community in a discussion about what can be done to increase PA in the South Asian community. METHODS: For this qualitative study, we conducted four Focus Group Discussions (FGDs) among a subset of participants who were part of a larger study. FGD data was coded and analysed using directed content analysis to identify key categories. RESULTS: Participants expressed a range of opinions, attitudes and beliefs about PA. Most believed they were sufficiently active. Women talked about restrictive social and cultural norms that discouraged uptake of exercise. Post-immigration levels of PA were low due to change in type of work and added responsibilities. CONCLUSION: Health promoters need to consider social, cultural, and structural contexts when exploring possible behavior change interventions for South Asian immigrants.

Aim: Cardiac arrest (CA) is the cessation of circulation to vital organs that can only be reversed with rapid and appropriate interventions. Sensor technologies for early detection and activation of the emergency medical system could enable rapid response to CA and increase the probability of survival. We conducted a systematic review to summarize the literature surrounding the performance of sensor technologies in detecting OHCA. Methods: We searched the academic and grey literature using keywords related to cardiac arrest, sensor technologies, and recognition/detection. We included English articles published up until June 6, 2022, including investigations and patent filings that reported the sensitivity and specificity of sensor technologies to detect cardiac arrest on human or animal subjects. (Prospero# CRD42021267797). Results: We screened 1666 articles and included four publications examining sensor technologies. One tested the performance of a physical sensor on human participants in simulated CA, one tested performance on audio recordings of patients in cardiac arrest, and two utilized a hybrid design for testing including human participants and ECG databases. Three of the devices were wearable and one was an audio detection algorithm utilizing household smart technologies. Real-world testing was limited in all studies. Sensitivity and specificity for the sensors ranged from 97.2 to 100% and 90.3 to 99.9%, respectively. All included studies had a medium/high risk of bias, with 2/4 having a high risk of bias. Conclusions: Sensor technologies show promise for cardiac arrest detection. However, current evidence is sparse and of high risk of bias. Small sample sizes and databases with low external validity limit the generalizability of findings.
RESUMEN
BACKGROUND: South Asians have high incidence of chronic disease. Physical activity (PA) and sedentary time are modifiable risk factors for chronic disease but their assessment in South Asians has been primarily based on self-report. This study presents directly-measured PA and sedentary time in South Asian adults in Canada. METHODS: A subset of 100 South Asian participants from a larger study who were identified at being at a higher risk for type 2 diabetes wore Actical accelerometers for 7 days. Anthropometric measures were taken and socio-demographic factors including age, income, education level, years since immigration, presence of children under the age of 12 years in the household and employment status were self-reported. RESULTS: Ninety-one participants (mean age 65.6 years) provided valid accelerometer data. Participants accumulated mean 673.5 (95% CI: 656.6, 691.0) min/day sedentary time, 130.5 (95% CI: 117.3, 145.3) min/day light PA (LPA) and 2.3 (95% CI: 1.3, 4.2) min/day moderate-to-vigorous PA (MVPA). For sedentary time and LPA, sex and BMI explained 51% of variability. For MVPA, BMI, season of assessment and employment status explained 23% variability with those who were employed accumulating significantly higher mean min/day of MVPA compared to those who were unemployed; (5.8, 95% CI: 1.5, 21.7) vs (1.5, 95% CI: 5.3, 20.0) respectively. CONCLUSION: High sedentary time, and low MVPA indicates the need to focus health promotion efforts on shifting sedentary time into LPA while trying to increase MVPA. Future studies need to be based on larger, representative samples of South Asians.

Fatigue is a common, debilitating, and poorly understood symptom post-COVID-19. We sought to better characterize differences in those with and without post-COVID-19 fatigue using cardiopulmonary exercise testing. Despite elevated dyspnoea intensity ratings, VÌO2peak (ml/kg/min) was the only significant difference in the physiological responses to exercise (19.9 ± 7.1 fatigue vs. 24.4 ± 6.7 ml/kg/min non-fatigue, p = 0.04). Consistent with previous findings, we also observed a higher psychological burden in those with fatigue in the context of similar resting cardiopulmonary function. Our findings suggest that lower cardiorespiratory fitness and/or psychological factors may contribute to post-COVID-19 fatigue symptomology. Further research is needed for rehabilitation and symptom management following SARS-CoV-2 infection.
