Assessing the impact of COVID-19 pandemic on the health of residents and the healthcare system in Alberta, Canada: an observational study-The Alberta POST-COVID Follow-up Study.

INTRODUCTION: Very little is known about how the COVID-19 pandemic has affected the health of residents and the healthcare system in Alberta, Canada. The purpose of this study is to establish an observational study to characterise the health of residents in Alberta, Canada, over time, covering a population that tested negative or positive for COVID-19 during the pandemic. The primary outcome is to characterise 'long COVID-19' and the health status of residents during the COVID-19 pandemic. Secondary outcomes include the estimation of the risk of and risk factors associated with adverse health outcomes and healthcare utilisation and burdens. METHODS AND ANALYSIS: This is a population-level provincial observational study which will follow-up with Alberta residents who underwent testing for COVID-19 and completed surveys adapted from the ISARIC COVID-19 long-term follow-up survey. The survey data will be linked with medical records. Statistical analyses will be carried out to characterise 'long COVID-19' and the health status of residents during the pandemic. The outcomes of this study will inform strategies for primary care and rehabilitation services to prevent chronic consequences; contribute to healthcare management, interventional studies, rehabilitation and health management to reduce overall morbidity and improve long-term outcomes of COVID-19 and the COVID-19 pandemic and potentially guide a self-evaluation of a remote monitoring system to manage individuals' health. ETHICS AND DISSEMINATION: This study was reviewed and approved by the University of Alberta ethics committee (Study ID: Pro00112053 & Pro00113039) on 13 August 2021 and adheres to the Alberta Health Services research information management policy. Study results will be used to manage clinical care, published in peer-reviewed journals and presented at local, national and international conferences.

Mental health and well-being of unpaid caregivers: a cross-sectional survey protocol.

INTRODUCTION: Unpaid caregiving, care provided by family/friends, is a public health issue of increasing importance. COVID-19 worsened the mental health conditions of unpaid caregivers, increasing substance/drug use and early development of chronic disease. The impact of the intersections of race and ethnicity, sex, age and gender along with unpaid care work and caregivers' health and well-being is unknown. The aim of this study is to describe the inequities of caregiver well-being across the intersections of race and ethnicity, sex, age and gender using a cross-sectional survey design. METHODS AND ANALYSIS: We are collaborating with unpaid caregivers and community organisations to recruit a non-probability sample of unpaid caregivers over 18 years of age (n=525). Recruitment will focus on a target sample of 305 South Asian, Chinese and Black people living in Canada, who represent 60% of the Canadian racial and ethnic populations. The following surveys will be combined into one survey: Participant Demographic Form, Caregiver Well-Being Index, interRAI Self-report of Carer Needs and the GENESIS (GENdEr and Sex DetermInantS of Cardiovascular Disease: From Bench to Beyond-Premature Acute Coronary Syndrome) PRAXY Questionnaire. Sample characteristics will be summarised using descriptive statistics. The scores from the Caregiver Well-Being Index will be dichotomised into fair/poor and good/excellent. A two-stage analytical strategy will be undertaken using logistic regression to model fair/poor well-being and good/excellent well-being according to the following axes of difference set a priori: sex, race and ethnicity, gender identity, age, gender relations, gender roles and institutionalised gender. The first stage of analysis will model the main effects of each factor and in the second stage of analysis, interaction terms will be added to each model. ETHICS AND DISSEMINATION: The University of Toronto's Health Sciences Research Ethics Board granted approval on 9 August 2022 (protocol number: 42609). Knowledge will be disseminated in pamphlets/infographics/email listservs/newsletters and journal articles, conference presentation and public forums, social media and through the study website. TRIAL REGISTRATION NUMBER: This is registered in the Open Sciences Framework with a Registration DOI as follows: https://doi.org/10.17605/OSF.IO/PB9TD.

Sex and Gender Impact Mental and Emotional Well-Being During COVID-19 Pandemic: A European Countries Experience.

Objective: The COVID-19 pandemic influences mental health drastically. Therefore, our aim was to investigate whether biological sex and gender-related factors are associated with mental health during the COVID-19 pandemic. Materials and Methods: The International COVID-19 Awareness and Responses Evaluation Study is an international multiwave cross-sectional observational cohort study of public awareness, attitudes, and responses to public health policies (www.mbmc- cmcm.ca/covid19). The study is led by the Montreal Behavioural Medicine Centre in collaboration with 200 international collaborators from 42 countries. It has received research ethics board approval from the Comité d'éthique de recherche du CIUSSS-NIM (Centre intégré universitaire de santé et de services sociaux du Nord- de-l'île-de-Montréal), approval no.: 2020-2099/25-03-2020. Recruitment began on March 27, 2020, and the survey is available in 34 languages. The associations between biological sex, sociocultural gender, and mental health were assessed in multivariate logistic regression models only for the European population (n = 12,300). Results: Positive correlations were found between female sex and "feeling nervous, anxious or worried" (OR = 3.2, p < 0.001, 95% CI 1.87-5.63) and "feeling sad, depressed or hopeless" (OR 1.8, p = 0.031, CI 1.05-3.05). Male sex was related to more frequently "feeling irritable, frustrated, and angry" (OR = 1.8, p = 0.04, 95% CI 1.03-2.99). Concerning gender, a negative correlation between being employed and "feeling lonely or isolated" (OR = 0.26, p < 0.001, 95% CI 0.11-0.59) was observed in the female cohort. Conclusion: Sex and gender differences exist in the emotional responses during the COVID-19 pandemic. Especially, within the female cohort, unemployment is negatively associated with mental health. Therefore, this study suggests more targeted psychological and social support for females during the pandemic.

Importance of sex and gender factors for COVID-19 infection and hospitalisation: a sex-stratified analysis using machine learning in UK Biobank data.

OBJECTIVE: To examine sex and gender roles in COVID-19 test positivity and hospitalisation in sex-stratified predictive models using machine learning. DESIGN: Cross-sectional study. SETTING: UK Biobank prospective cohort. PARTICIPANTS: Participants tested between 16 March 2020 and 18 May 2020 were analysed. MAIN OUTCOME MEASURES: The endpoints of the study were COVID-19 test positivity and hospitalisation. Forty-two individuals' demographics, psychosocial factors and comorbidities were used as likely determinants of outcomes. Gradient boosting machine was used for building prediction models. RESULTS: Of 4510 individuals tested (51.2% female, mean age=68.5±8.9 years), 29.4% tested positive. Males were more likely to be positive than females (31.6% vs 27.3%, p=0.001). In females, living in more deprived areas, lower income, increased low-density lipoprotein (LDL) to high-density lipoprotein (HDL) ratio, working night shifts and living with a greater number of family members were associated with a higher likelihood of COVID-19 positive test. While in males, greater body mass index and LDL to HDL ratio were the factors associated with a positive test. Older age and adverse cardiometabolic characteristics were the most prominent variables associated with hospitalisation of test-positive patients in both overall and sex-stratified models. CONCLUSION: High-risk jobs, crowded living arrangements and living in deprived areas were associated with increased COVID-19 infection in females, while high-risk cardiometabolic characteristics were more influential in males. Gender-related factors have a greater impact on females; hence, they should be considered in identifying priority groups for COVID-19 infection vaccination campaigns.

Impact of biological sex and gender-related factors on public engagement in protective health behaviours during the COVID-19 pandemic: cross-sectional analyses from a global survey.

OBJECTIVE: Given the role of sociocultural gender in shaping human behaviours, the main objective of this study was to examine whether sex and gender-related factors were associated with the public's adherence to COVID-19-recommended protective health behaviours. DESIGN: This was a retrospective analysis of the survey that captured data on people's awareness, attitudes and behaviours as they relate to the COVID-19 policies. SETTING: Data from the International COVID-19 Awareness and Responses Evaluation survey collected between March 2020 and February 2021 from 175 countries. PARTICIPANTS: Convenience sample around the world. MAIN OUTCOME MEASURES: We examined the role of sex and gender-related factors in relation to non-adherence of protective health behaviours including: (1) hand washing; (2) mask wearing; and (3) physical distancing. Multivariable logistic regression was conducted to determine the factors associated with non-adherence to behaviours. RESULTS: Among 48 668 respondents (mean age: 43 years; 71% female), 98.3% adopted hand washing, 68.5% mask wearing and 76.9% physical distancing. Compared with males, females were more likely to adopt hand washing (OR=1.97, 95% CI: 1.71 to 2.28) and maintain physical distancing (OR=1.28, 95% CI: 1.22 to 1.34). However, in multivariable sex-stratified models, females in countries with higher Gender Inequality Indexes (GII) were less likely to report hand washing (adjusted OR (aOR)=0.47, 95% CI: 0.21 to 1.05). Females who reported being employed (aOR=0.22, 95% CI: 0.10 to 0.48) and in countries with low/medium GIIs (aOR=0.18, 95% CI 0.06 to 0.51) were less likely to report mask wearing. Females who reported being employed were less likely to report physical distancing (aOR=0.39, 95% CI: 0.32 to 0.49). CONCLUSION: While females showed greater adherence to COVID-19 protective health behaviours, gender-related factors, including employment status and high country-wide gender inequality, were independently associated with non-adherence. These findings may inform public health and vaccination policies in current as well as future pandemics.

Predicting the Risk Factors Associated With Severe Outcomes Among COVID-19 Patients-Decision Tree Modeling Approach.

Background: The COVID-19 pandemic has seen a large surge in case numbers over several waves, and has critically strained the health care system, with a significant number of cases requiring hospitalization and ICU admission. This study used a decision tree modeling approach to identify the most important predictors of severe outcomes among COVID-19 patients. Methods: We identified a retrospective population-based cohort (n = 140,182) of adults who tested positive for COVID-19 between 5th March 2020 and 31st May 2021. Demographic information, symptoms and co-morbidities were extracted from a communicable disease and outbreak management information system and electronic medical records. Decision tree modeling involving conditional inference tree and random forest models were used to analyze and identify the key factors(s) associated with severe outcomes (hospitalization, ICU admission and death) following COVID-19 infection. Results: In the study cohort, nearly 6.37% were hospitalized, 1.39% were admitted to ICU and 1.57% died due to COVID-19. Older age (>71Y) and breathing difficulties were the top two factors associated with a poor prognosis, predicting about 50% of severe outcomes in both models. Neurological conditions, diabetes, cardiovascular disease, hypertension, and renal disease were the top five pre-existing conditions that altogether predicted 29% of outcomes. 79% of the cases with poor prognosis were predicted based on the combination of variables. Age stratified models revealed that among younger adults (18-40 Y), obesity was among the top risk factors associated with adverse outcomes. Conclusion: Decision tree modeling has identified key factors associated with a significant proportion of severe outcomes in COVID-19. Knowledge about these variables will aid in identifying high-risk groups and allocating health care resources.

Bedtime versus morning use of antihypertensives for cardiovascular risk reduction (BedMed): protocol for a prospective, randomised, open-label, blinded end-point pragmatic trial.

Healthcare workers' perception of gender and work roles during the COVID-19 pandemic: a mixed-methods study.

OBJECTIVES: A high functioning healthcare workforce is a key priority during the COVID-19 pandemic. We sought to determine how work and mental health for healthcare workers changed during the COVID-19 pandemic in a universal healthcare system, stratified by gender factors. DESIGN: A mixed-methods study was employed. Phase 1 was an anonymous, internet-based survey (7 May-15 July 2020). Phase 2 was semistructured interviews offered to all respondents upon survey completion to describe how experiences may have differed by gender identity, roles and relations. SETTING: National universal healthcare system (Canada). PARTICIPANTS: 2058 Canadian healthcare worker survey respondents (87% women, 11% men, 1% transgender or Two-Spirit), including 783 health professionals, 673 allied health professionals, 557 health support staff. Of the 63 unique healthcare worker types reported, registered nurses (11.5%), physicians (9.9%) and pharmacists (4.5%) were most common. Forty-six healthcare workers were interviewed. MAIN OUTCOME MEASURES: Reported pandemic-induced changes to occupational leadership roles and responsibilities, household and caregiving responsibilities, and anxiety levels by gender identity. RESULTS: Men (19.8%) were more likely to hold pandemic leadership roles compared with women (13.4%). Women (57.5%) were more likely to report increased domestic responsibilities than men (45%). Women and those with dependents under the age of 10 years reported the greatest levels of anxiety during the pandemic. Interviews with healthcare workers further revealed a perceived imbalance in leadership opportunities based on gender identity, a lack of workplace supports disproportionately affecting women and an increase in domestic responsibilities influenced by gender roles. CONCLUSIONS: The COVID-19 pandemic response has important gendered effects on the healthcare workforce. Healthcare workers are central to effective pandemic control, highlighting an urgent need for a gender-transformative pandemic response strategy.

Virtual visits in cardiovascular disease: a rapid review of the evidence.

Given the high prevalence of cardiovascular disease (CVD) in Canada and globally, as well as the staggering cost to human life and health systems, there is an urgent need to understand the successful applications of telemedicine in cardiovascular medicine. While telemedicine in cardiology is well documented, reports on virtual care in the form of synchronous, real-time communication between healthcare providers and patients are limited. As a result of the immediate suspension of ambulatory services for cardiology in Alberta, Canada, due to the Coronavirus Disease 2019 pandemic, we undertook a rapid review on the impact of non-virtual visits in cardiovascular ambulatory settings on patients' healthcare utilization and mortality. Evidence from 12 randomized control trials and 7 systematic reviews was included in the rapid review, with the majority of papers (n = 15) focusing on telemedicine in heart failure. Based on our appraisal of evidence from the last 5 years, virtual visits are non-inferior, or more effective, in reducing hospitalizations and visits to emergency departments in patients with CVD compared to traditional standard in-clinic/ambulatory care. The evidence for a superior effect of virtual visits in reducing mortality was not supported in this review. While telemedicine is an appropriate tool for CVD follow-up care, more research into the efficacy of different components of telemedicine and virtual visits is required.

Sex differences in COVID-19: candidate pathways, genetics of ACE2, and sex hormones.

Biological sex is increasingly recognized as a critical determinant of health and disease, particularly relevant to the topical COVID-19 pandemic caused by the SARS-CoV-2 coronavirus. Epidemiological data and observational reports from both the original SARS epidemic and the most recent COVID-19 pandemic have a common feature: males are more likely to exhibit enhanced disease severity and mortality than females. Sex differences in cardiovascular disease and COVID-19 share mechanistic foundations, namely, the involvement of both the innate immune system and the canonical renin-angiotensin system (RAS). Immunological differences suggest that females mount a rapid and aggressive innate immune response, and the attenuated antiviral response in males may confer enhanced susceptibility to severe disease. Furthermore, the angiotensin-converting enzyme 2 (ACE2) is involved in disease pathogenesis in cardiovascular disease and COVID-19, either to serve as a protective mechanism by deactivating the RAS or as the receptor for viral entry, respectively. Loss of membrane ACE2 and a corresponding increase in plasma ACE2 are associated with worsened cardiovascular disease outcomes, a mechanism attributed to a disintegrin and metalloproteinase (ADAM17). SARS-CoV-2 infection also leads to ADAM17 activation, a positive feedback cycle that exacerbates ACE2 loss. Therefore, the relationship between cardiovascular disease and COVID-19 is critically dependent on the loss of membrane ACE2 by ADAM17-mediated proteolytic cleavage. This article explores potential mechanisms involved in COVID-19 that may contribute to sex-specific susceptibility focusing on the innate immune system and the RAS, namely, genetics and sex hormones. Finally, we highlight here the added challenges of gender in the COVID-19 pandemic.
