Mental Health and Dispositional Predictors of Simultaneous Versus Concurrent Cannabis and Alcohol Use in a Canadian Context.

Objective: Cannabis has become more available in Canada since its legalization in 2018. Many individuals who use cannabis also use alcohol (co-use), which can be used either at the same time such that their effects overlap (simultaneous use) or at different times (concurrent use). Though studies have identified predictors of co-use relative to single-substance use, less is known about the predictors of specific types of co-use.

Examining the Relationship Between Cannabis Use and Mood, Anxiety, and Psychotic Symptoms in Psychiatric Patients with Severe Concurrent Mental Health and Substance Use Disorders Before and After Recreational Cannabis Legalization in Canada.

Objective: The relationship between cannabis use and mental health has garnered significant attention in recent decades. However, studies have largely been in general populations or in countries in which recreational cannabis use is illegal.

Method: The current cross-sectional study examines the relationship between cannabis use, mood disorders, anxiety, and psychosis in an inpatient psychiatric population with severe concurrent mental health and substance use disorders, exploring the potential moderating effect of the legalization of recreational cannabis in Canada.

Preparation, articulation, and photogrammetry of a neonatal moose skeleton.

Objective: Neonatal skeletal articulations for research and display purposes are uncommon due to issues surrounding incomplete bone maturation and reduced structural integrity that affect the bone preparation and articulation procedures. The present project was designed to add to the veterinary literature on neonatal moose osteological specimens, document the procedures of preparing and articulating a delicate specimen, and construct a 3-dimensional (3D) scan of the articulated skeleton that could be used for scientific and veterinary research and study worldwide.

Animal: A neonatal moose that had succumbed to capture myopathy resulting from entanglement in a barbed wire fence was the sole subject of this project.

Hepatic infection in a dog with cavitary lung disease.

A 9-year-old neutered male cairn terrier dog was initially presented because of inappetence, increased respiratory effort, and occasional coughing. A cavitary lung mass was diagnosed using CT and removed with lung lobectomy. Histopathology of the mass revealed necrosuppurative inflammation with acid-fast rod bacteria in macrophages, with spp.

How Marine Megabenthos Fauna Responds to River Discharge and Artificial Flood in Large River Estuary.

Estuaries are ecologically sensitive areas influenced by river regulation. Knowledge of how marine megabenthos responds to river regulation and artificial flooding events remains limited. The study aims to provide a comprehensive understanding of the impacts of river regulation on marine megabenthic fauna.

The prevalence of HIV pre-exposure prophylaxis (HIV-PrEP) use and HIV-PrEP-to-need ratio in nine Canadian provinces, 2018-2021.

Background: Measuring trends in HIV pre-exposure prophylaxis (HIV-PrEP) uptake is important to inform planning for prevention programs and policies. The HIV-PrEP-to-need ratio (PnR) is a construct used by public health organizations to explore disparities in the provision of HIV-PrEP across geographic areas and demographic categories (e.g.

Burden of disease of respiratory syncytial virus in older adults and adults considered at high risk of severe infection.

Background: Availability of new vaccines for adults has increased interest in understanding Canada's respiratory syncytial virus (RSV) burden in older adults and adults considered at high risk of severe infection.

Objective: To characterize the burden of RSV disease in Canada by joint analysis of the published literature and hospitalization data from a healthcare administrative database.

Methods: Electronic databases of published literature were searched to identify studies and systematic reviews reporting data on outpatient visits, hospitalizations, intensive care unit (ICU) admissions and deaths associated with RSV infection in adults.

Prior thermal acclimation gives White Sturgeon a fin up dealing with low oxygen.

Assessing how at-risk species respond to co-occurring stressors is critical for predicting climate change vulnerability. In this study, we characterized how young-of-the-year White Sturgeon () cope with warming and low oxygen (hypoxia) and investigated whether prior exposure to one stressor may improve the tolerance to a subsequent stressor through "cross-tolerance". Fish were acclimated to five temperatures within their natural range (14-22°C) for one month prior to assessment of thermal tolerance (critical thermal maxima, CTmax) and hypoxia tolerance (incipient lethal oxygen saturation, ILOS; tested at 20°C).

Establishment of Mongolia's first independent and sustainable minimally invasive general thoracic surgery program: A Mongolian-Canadian initiative.

Objective: The advent of video-assisted thoracoscopic surgery in Mongolia has faced funding and accessibility challenges, leading to languid adoption. A Mongolian-Canadian collaboration was inaugurated to support the development of a self-sustainable, self-governed minimally invasive thoracic surgery (MITS) program in Mongolia.

Methods: A multidisciplinary Canadian thoracic surgery team collaborated with the National Cancer Center of Mongolia Thoracic Surgery service from 2016 to 2023.

The effect of environmental factors on transepithelial potential in a model Amazonian teleost, the tambaqui (Colossoma macropomum): Implications for sodium balance in harsh environments.

The tambaqui (Colossoma macropomum, G. Cuvier 1818) thrives both in the ion-poor waters of the Amazon and in commercial aquaculture. In both, environmental conditions can be harsh due to low ion levels, occasional high salt challenges (in aquaculture), low pH, extreme PO levels (hypoxia and hyperoxia), high PCO levels (hypercapnia), high ammonia levels (in aquaculture), and high and low temperatures.

Intertwined people-nature relations are central to nature-based adaptation to climate change.

Adaptation to climate change is a social-ecological process: it is not solely a result of natural processes or human decisions but emerges from multiple relations within social systems, within ecological systems and between them. We propose a novel analytical framework to evaluate social-ecological relations in nature-based adaptation, encompassing social (people-people), ecological (nature-nature) and social-ecological (people-nature) relations. Applying this framework to 25 case studies, we analyse the associations among these relations and identify archetypes of social-ecological adaptation.

Quality of Non-Surgical and Non-Pharmacological Knee Osteoarthritis Care in the Maritimes.

Objectives: To evaluate the quality and types of care individuals with mild-to-moderate knee osteoarthritis receive in the Canadian Maritime provinces, and determine associations with demographic, social, and patient-reported factors.

Methods: Individuals with knee osteoarthritis were invited to complete a healthcare quality survey based on the British Columbia Osteoarthritis (BC OA) survey. The cross-sectional descriptive observational survey assessed four healthcare quality indicators: advice to exercise, advice to lose weight, assessment of ambulatory function, and assessment of non-ambulatory function.

Biochemical and structural characterization of Rab3GAP reveals insights into Rab18 nucleotide exchange activity.

The heterodimeric Rab3GAP complex is a guanine nucleotide exchange factor (GEF) for the Rab18 GTPase that regulates lipid droplet metabolism, ER-to-Golgi trafficking, secretion, and autophagy. Why both subunits of Rab3GAP are required for Rab18 GEF activity and the molecular basis of how Rab3GAP engages and activates its cognate substrate are unknown. Here we show that human Rab3GAP is conformationally flexible and potentially autoinhibited by the C-terminal domain of its Rab3GAP2 subunit.

Higher spatial resolution is not always better: evaluating satellite-sensed sea surface temperature products for a west Pacific coral reef system.

As marine heatwaves and mass coral bleaching events rise in frequency and severity, there is an increasing need for high-resolution satellite products that accurately predict reef thermal environments over large spatio-temporal scales. Deciding which global sea surface temperature (SST) dataset to use for research or management depends in part on the desired spatial resolution. Here, we evaluate two SST datasets - the lower-resolution CoralTemp v3.

DJK-5, an anti-biofilm peptide, increases Staphylococcus aureus sensitivity to colistin killing in co-biofilms with Pseudomonas aeruginosa.

Chronic infections represent a significant global health and economic challenge. Biofilms, which are bacterial communities encased in an extracellular polysaccharide matrix, contribute to approximately 80% of these infections. In particular, pathogens such as Pseudomonas aeruginosa and Staphylococcus aureus are frequently co-isolated from the sputum of patients with cystic fibrosis and are commonly found in chronic wound infections.

The impact of an interactive online informational and peer support application (app) for patients with low anterior resection syndrome (LARS) on quality of life: a multicenter randomized controlled trial.

Introduction: Low Anterior Resection Syndrome (LARS) describes bowel dysfunction post-restorative proctectomy (RP) and is associated with poor quality of life (QoL). The aim of this study was to assess the impact of an interactive online informational and peer support App on participants' QoL (primary outcome), LARS, and emotional distress (secondary outcomes).

Methods: A multicentre, randomized, parallel-group trial was conducted across five Canadian colorectal surgery practices.

Milk feeding and calf housing practices on British Columbia dairy farms.

Decades of research have helped inform practices on how to care for calves, but little is known about how well these practices are adopted on commercial dairy farms. The primary aim of this study was to describe rearing practices of dairy calves in British Columbia, Canada. Measures of calf growth are sometimes used to assess success in calf rearing, so a secondary aim was to describe methods used to assess calf growth on these farms.

Characterizing the urobiome and associated metabolic profiles during acute rejection in renal transplant patients: A pilot study.

Characteristic alterations in the urinary microbiome, or urobiome, are associated with renal transplant pathology. To date, there has been no direct study of the urobiome during acute allograft rejection. The goal of this study was to determine if unique urobiome alterations are present during acute rejection in renal transplant recipients.

Current evidence around key underrepresented women's health topics in pregnancy and postpartum nutrition: a narrative review.

Adequate nutrition during pregnancy and postpartum is critical to maternal and child health, but there is often a missing focus around health outcomes specifically for women. Women's health includes sex-specific biological attributes and socially constructed gender roles framing behaviours and practices. This narrative review aims to highlight key areas where women's health has been underrepresented in pregnancy and postpartum nutrition research.

Social Disengagement in Post-Pandemic China: A Translation, Validation and Cross-Cultural Comparison of the Pandemic Disengagement Syndrome Scale.

Background: In contrast to abundant research on the various acute mental effects of COVID-19, the long-term influences of the pandemic are still underexplored in China owing to the paucity of assessment tools. The Pandemic Disengagement Syndrome Scale (PDSS) assesses people's social disengagement as a lasting psychological consequence in Western countries during the post-COVID-19 pandemic era. However, its generalizability across cultures is untested.

Examining the effects of race/ethnicity and other factors on outcomes of care for complex regional pain syndrome type 1 in the United States.

Complex regional pain syndrome is a chronic pain disorder marked by symptoms such as swelling, impaired motor function, and sympathetic dysfunction. Our primary objective was to determine the total number of complex regional pain syndrome type 1 (CRPS-1) emergency department (ED) visits and hospitalizations by race/ethnicity, as well as to assess sex and age distributions by race/ethnicity. Secondary objectives were to examine whether race/ethnicity, as well as select characteristics, are associated with hospitalization and longer length of stay.
