Supporting young people through the COVID-19 pandemic and beyond: a multi-site qualitative longitudinal study.

Background: Throughout the COVID-19 pandemic, youth have experienced substantial stress due to abrupt changes in education, finances, and social life, compounding pre-existing stressors. With youth (ages 15-26) often at critical points in development, they are vulnerable to long-term mental health challenges brought on by pandemic trauma.

Methods: To identify youth experiences throughout the pandemic and examine changes over time, we conducted semi-structured interviews among n = 141 youth in two Canadian provinces (Ontario and British Columbia) and across the country of Ireland at three time points over the course of more than one year (August 2020-October 2021).

Changes in hepatic steatosis before and after direct acting antiviral treatment in people living with HIV and Hepatitis C coinfection.

Background: Both HIV and hepatitis C virus (HCV) infection increase the risk of hepatic steatosis (HS), which in turn contributes to the severity and progression of liver disease. Direct acting antivirals (DAAs) can cure HCV but whether they reduce HS is unclear.

Methods: HS was assessed using the controlled attenuation parameter (CAP) and the hepatic steatosis index (HSI) in participants coinfected with HIV-HCV from the Canadian Coinfection Cohort.

Population perinatal substance use and an environmental scan of health services in British Columbia, Canada.

Background: Substance use during pregnancy is underreported globally and there is limited data on its prevalence and the availability of supportive services. This study determined population perinatal substance use in British Columbia (BC) by region and examined the availability of clinical and community-based programs.

Methods: Using linked provincial health administrative data, we conducted a population-based retrospective cohort study including all BC residents accessing care for substance use (alcohol, opioids, stimulants, sedatives, and cannabis) within 12 months of first perinatal care record to delivery during 2016-2021.

Detecting cardiac states with wearable photoplethysmograms and implications for out-of-hospital cardiac arrest detection.

Out-of-hospital cardiac arrest (OHCA) is a global health problem affecting approximately 4.4 million individuals yearly. OHCA has a poor survival rate, specifically when unwitnessed (accounting for up to 75% of cases).

The Longitudinal Evidence on Social Ties and Fruit and Vegetable Intake among Aging Adults: A Systematic Review.

Context: Social ties are associated with the mortality and morbidity of aging populations; however, the role of social ties in healthy eating practices or gender differences in this link is less understood.

Objective: The objective of this study was to examine the longitudinal evidence for the impact of changes in social ties on fruit and vegetable (FV) intakes among aging adults, with attention to gender differences.

Data Sources: Medline, Embase, Scopus, CINAHL, and ProQuest databases were searched until December 2022.

Access and barriers to safer supply prescribing during a toxic drug emergency: a mixed methods study of implementation in British Columbia, Canada.

Background: In March 2020, British Columbia, Canada, introduced prescribed safer supply involving the distribution of pharmaceutical grade alternatives to the unregulated toxic drug supply. Prior research has demonstrated positive impacts on overdose mortality, but with limited reach to people who use substances. Objectives of this study were to (1) identify barriers to accessing safer supply prescribing among people who use substances; and (2) determine whether and how barriers differed between people with and without prescriptions, and between urban and rural settings.

Trends, transitions and patterning in social activity over time among aging women and men: A secondary analysis of the Canadian Longitudinal Study on Aging (CLSA).

Social isolation matters for health and longevity, but little research examines transitions into or out of social isolation or whether transitions are gendered or socially patterned. We described gender-specific trends in breadth and lack of social participation over 6 years overall and by age, country of origin, geographic location, education, wealth, and household income. We used three waves of CLSA data to evaluate changes in social isolation (0-1 activities) and broad social participation (5+ activities) in adults aged 45-75 (n = 24,788), by gender and socio-demographics, in linear and multinomial logistic regressions with post-estimated predicted probabilities.

Characteristics of lung resistance and elastance associated with tracheal stenosis and intrapulmonary airway narrowing in ex vivo sheep lungs.

Increases in housing rules and surveillance during COVID-19: impacts on overdose and overdose response in a community-based cohort of sex workers who use drugs in Vancouver, BC.

Introduction: Since the beginning of the COVID-19 pandemic, COVID-19 risk mitigation measures have expanded to include increased rules and surveillance in supportive housing. Yet, in the context of the dual public health emergencies of COVID-19 and the unregulated drug toxicity crisis, we have not evaluated the unintended health and social consequences of such measures, especially on criminalized women. In order to address this dearth of evidence, our aim was to assess the association between increased housing rules and surveillance during COVID-19 and (a) nonfatal overdose, and (b) administration of naloxone for overdose reversal among women sex workers who use drugs in Vancouver, BC.

AN EVALUATION OF INDOOR SEX WORKERS' PSYCHOSOCIAL OCCUPATIONAL HEALTH AND SAFETY IN METRO VANCOUVER, CANADA.

Criminalization of sex work is linked to increased risk of violence and lack of workplace protections for sex workers. Most jurisdictions globally prohibit some or all aspects of sex work with New Zealand constituting a notable exception, where sex work has been decriminalized and regulated via OHS guidelines. We used the as an analytical framework to examine the lived-experiences of psychosocial OHS conditions of indoor sex workers in Metro Vancouver under end-demand criminalization.

Interleukin-1α inhibits transforming growth factor-β1 and β2-induced extracellular matrix production, remodeling and signaling in human lung fibroblasts: Master regulator in lung mucosal repair.

Background: Lung fibroblasts play a central role in maintaining lung homeostasis and facilitating repair through the synthesis and organization of the extracellular matrix (ECM). This study investigated the cross-talk between interleukin-1 alpha (IL-1α) and transforming growth factor-β (TGF-β) signaling, two key regulators in tissue repair and fibrosis, in the context of lung fibroblast repair in the healthy lung.

Results: Stimulation of lung fibroblasts with TGF-β1 and TGF-β2 induced collagen-I and fibronectin protein expression (p < 0.

A case study of the DULF compassion club and fulfillment centre-A logical step forward in harm reduction.

In 2022, the Drug User Liberation Front's Compassion Club and Fulfillment Centre emerged as a groundbreaking initiative and research endeavor aimed at addressing the alarming rise in overdose deaths within Vancouver's Downtown Eastside. As the first of its kind, this pioneering model operated as a non-profit, low-barrier, and non-medicalized approach to regulating the volatility of the content of the illicit drug market in order to prevent overdose deaths. Going beyond traditional overdose prevention methods, the Drug User Liberation Front's Compassion Club and Fulfillment Centre not only provided supervised consumption services, but also supplied rigorously tested cocaine, heroin, and methamphetamine at cost to club members.

Can supervised deep learning architecture outperform autoencoders in building propensity score models for matching?

Purpose: Propensity score matching is vital in epidemiological studies using observational data, yet its estimates relies on correct model-specification. This study assesses supervised deep learning models and unsupervised autoencoders for propensity score estimation, comparing them with traditional methods for bias and variance accuracy in treatment effect estimations.

Methods: Utilizing a plasmode simulation based on the Right Heart Catheterization dataset, under a variety of settings, we evaluated (1) a supervised deep learning architecture and (2) an unsupervised autoencoder, alongside two traditional methods: logistic regression and a spline-based method in estimating propensity scores for matching.

Breastfeeding and Neonatal Age Influence Neutrophil-Driven Ontogeny of Blood Cell Populations in the First Week of Human Life.

The first few days of life are characterized by rapid external and internal changes that require substantial immune system adaptations. Despite growing evidence of the impact of this period on lifelong immune health, this period remains largely uncharted. To identify factors that may impact the trajectory of immune development, we conducted stringently standardized, high-throughput phenotyping of peripheral white blood cell (WBC) populations from 796 newborns across two distinct cohorts (The Gambia, West Africa; Papua New Guinea, Melanesia) in the framework of a Human Immunology Project Consortium (HIPC) study.

The effect of the mechanodynamic lung environment on fibroblast phenotype via the Flexcell.

The lung is a highly mechanical organ as it is exposed to approximately 10 strain cycles, (where strain is the length change of tissue structure per unit initial length), with an approximately 4% amplitude change during quiet tidal breathing or 10 strain cycles at a 25% amplitude during heavy exercises, sighs, and deep inspirations. These mechanical indices have been reported to become aberrant in lung diseases such as acute respiratory distress syndrome (ARDS), pulmonary hypertension, bronchopulmonary dysplasia (BPD), idiopathic pulmonary fibrosis (IPF), and asthma. Through recent innovations, various in vitro systems/bioreactors used to mimic the lung's mechanical strain have been developed.
