The St. Lawrence Estuary (SLE) beluga () population in Canada is Endangered, and endocrine disrupting contaminants, such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and other halogenated flame retardants, have been identified as a threat to the recovery of this population. Here, potential impacts of these contaminants on SLE beluga were evaluated by comparing skin transcriptome profiles and biological pathways between this population and a population less exposed to contaminants (Eastern Beaufort Sea) used as a reference.

Adult neurogenesis has most often been studied in the hippocampus and subventricular zone-olfactory bulb, where newborn neurons contribute to a variety of behaviors. A handful of studies have also investigated adult neurogenesis in other brain regions, but relatively little is known about the properties of neurons added to non-canonical areas. One such region is the striatum.

Treated municipal wastewater effluent is an important pathway for Contaminants of Emerging Concern (CEC) to enter aquatic ecosystems. As the aging wastewater infrastructure in many industrialized countries requires upgrades or replacement, assessing new treatment technologies in the context of CEC effects may provide additional support for science-based resource management. Here, we used three lines of evidence, analytical chemistry, fish exposure experiments, and fish and water microbiome analysis, to assess the effectiveness of membrane bioreactor treatment (MBR) to replace traditional activated sludge treatment.

Purpose Of Review: Trigeminal neuralgia (TN) is a highly heterogeneous condition with a wide choice of successful treatment options. However, differences between subtypes are poorly understood and it remains unknown which patients will respond to different treatments. This review aims to summarize the current state of the TN field and explore the problem of predicting surgical outcomes.

Background: There are limited data on duration of aromatase inhibitor (AI) and cardiovascular disease (CVD) risk in breast cancer (BC) survivors. We examined risk of CVD and mortality associated with duration of AI use in postmenopausal women with early-stage hormone receptor-positive BC.

Methods: Postmenopausal women diagnosed with hormone receptor-positive BC (n = 5,853) who used an AI were included.

Machine learning reveals the dynamic importance of accessory sequences for outbreak clustering.

mBio

January 2025

Department of Molecular Biology and Biochemistry, Simon Fraser University, Burnaby, British Columbia, Canada.

Unlabelled: Bacterial typing at whole-genome scales is now feasible owing to decreasing costs in high-throughput sequencing and the recent advances in computation. The unprecedented resolution of whole-genome typing is achieved by genotyping the variable segments of bacterial genomes that can fluctuate significantly in gene content. However, due to the transient and hypervariable nature of many accessory elements, the value of the added resolution in outbreak investigations remains disputed.

Selection on animal signal form often changes significantly with the environment, yet signal form may itself be environment dependent. Little is known about how variation in individual responses to changing environments affects the relationship between selection and the subsequent evolution of signal traits. To address this question, we assess the effects of variation in temperature on individual signaling and mating behavior responses across temperatures in the wolf spider Schizocosa floridana.

Maternal diet has long-term effects on offspring brain development and behavior. Sucrose (table sugar) intakes are high in modern diets, but it is not clear how a maternal high-sucrose diet (HSD) affects the offspring. In rats, a maternal HSD (26% of calories from sucrose, which is human-relevant) alters maternal metabolism and brain and also alters adult offspring endocrinology and behavior in a sex-specific manner.

Objective: To evaluate the association between tumour size and the growth rate (GR) of small renal masses (SRMs) in patients managed by active surveillance (AS).

Materials And Methods: We queried the prospective, multi-institutional Delayed Intervention and Surveillance for Small Renal Masses (DISSRM) registry for patients on AS with an imaging interval of ≥6 months, identifying 456 patients. We tracked tumour size over time; a GR >0.

People living with HIV (PLWH) in Canada experience high rates of interpersonal violence which may lead to adverse health outcomes that require hospitalization. Using self-reported data on experiences of violence linked to administrative health data on hospitalizations, we used Poisson regression modelling to examine and compare the associations between experiences of violence (recent [in the past 6 months], non-recent [>6 months ago], or none) and hospitalization rates, among a sample of PLWH in British Columbia, Canada. Of 984 PLWH included in this study, 60.

Although many parents worry that their child will be the target of racial profiling, there is a dearth of literature on how parental worries about children facing racism are linked to racial socialization (RS) practices and youth internalizing symptoms. Additionally, it is unclear how RS content relative to competency may uniquely influence whether and how parental worries influence youth internalizing outcomes. Using data from 203 Black parents (M = 44.

Exploratory laparotomies for blunt or penetrating trauma often result in significant morbidity. Despite advancements in resuscitation, surgical techniques, and antibiotics, intra-abdominal abscesses remain a serious complication, contributing to poor outcomes and extended hospital stays. Percutaneous computed tomography-guided drainage is the standard treatment for abscesses, offering high success rates and low morbidity.

Background: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is typically diagnosed following an arrhythmic event or during screening after a family member experiences sudden cardiac death. Implantation of a defibrillator (ICD) improves survival but can be associated with morbidity and risks, an important consideration within a shared decision-making context. This study examined patient decisional needs and preferences surrounding ARVC screening and prophylactic ICD implantation.

Background: Out-of-hospital cardiac arrest (OHCA) remains a prominent medical concern worldwide. Epidemiologic metrics and trends over time for OHCA cases in Canada are not well defined. This study evaluated geographic differences in the incidence and outcomes of OHCA patients admitted to hospitals across Canada, during the period 2013-2017.

Background: Guideline-directed medical therapy (GDMT) reduces events in patients with heart failure (HF) with reduced ejection fraction (HFrEF). Despite this impact, underutilization of GDMT persists. This report sought to describe HF management in Canadian outpatients treated at specialized HF clinics (HFCs).

Idiopathic inflammatory myopathies (IIM), or myositis, are a heterogeneous group of autoimmune disorders that can affect multiple organs, including the muscles, skin, joints, lungs, heart, and gastrointestinal tract. While new-onset myositis has been reported following SARS-CoV-2 infection, cases associated with COVID-19 vaccination remain rare. We describe a unique case of severe progressive edematous facial myositis resembling angioedema in a 22-year-old man, with onset one to two weeks after receiving dual SARS-CoV-2 and influenza vaccinations.

Coronary artery disease (CAD) is associated with poor outcomes after orthotopic liver transplantation (OLT). We report on six high-risk end-stage liver disease (ESLD) patients who underwent percutaneous coronary intervention (PCI) with bare metal stents during the preoperative evaluation process. There was no mortality or major adverse cardiac event (MACE) within 90 days of OLT.
