Intrinsic and environmental drivers of pairwise cohesion in wild Canis social groups.

Ecology

January 2025

Wildlife Research and Monitoring Section, Ministry of Natural Resources and Forestry, Peterborough, Ontario, Canada.

Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group-level processes such as subgroup formation and fission-fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing cohesion remains a gap in our knowledge of cooperative behavior in animals.

Identifying factors that drive among-individual variation in mixed parasitic infections is fundamental to understanding the ecology and evolution of host–parasite interactions. However, a lack of non-invasive diagnostic tools to quantify mixed infections has restricted their investigation for host populations in the wild. This study applied DNA metabarcoding on parasite larvae cultured from faecal samples to characterize mixed strongyle infections of 320 feral horses on Sable Island, Nova Scotia, Canada, in 2014 to test for the influence of host (age, sex and reproductive/social status) and environmental (location, local density and social group membership) factors on variation.

Dental trauma is highly prevalent, involving 25% of school-age children and about 12.5% of the general population of the world. Due to the young age of the patients that are usually involved in dental trauma, there are tooth-related complicating factors, such as open apices, thin dentinal walls, and unfavorable crown-to-root ratio, as well as patient-related factors, such as anxiety and cooperation, and other challenges related to the complex diagnosis and treatment.

Article Synopsis
  • PMMA materials are prone to microbial growth, leading to potential oral infections in patients, which prompted a study using montmorillonite clay (MMT) combined with antimicrobial agents like chlorhexidine (CHX) and metronidazole (MET) to improve resistance.
  • The researchers created three groups of PMMA samples—control (no nanoparticles), MMT/CHX, and MMT/MET—and tested their mechanical properties and antimicrobial effectiveness against bacteria such as Enterococcus faecalis and Porphyromonas gingivalis.
  • Results showed that MMT/CHX maintained PMMA’s mechanical strength while exhibiting antibacterial properties, whereas MMT/MET negatively impacted strength, leading to the conclusion that MMT/CHX is the

Introduction: In 2018, competency-based medical education (CBME) was introduced to Canadian urology residency training. We examined learner and faculty experiences with CBME five years post-implementation.

Methods: Two online surveys were developed from a scoping review of CBME literature and expert consultation.

Article Synopsis
  • The study focuses on developing a fully automated segmentation method for spinal MRI images using a convolutional-deconvolution neural network to improve efficiency and accuracy in diagnosing spinal diseases.
  • A combination of patch extraction and feature representation techniques allows the model to effectively learn and accurately segment spine MRI data, resulting in high precision and performance metrics compared to traditional methods.
  • Experimental results demonstrate the proposed method's capability, achieving impressive statistics (e.g., 91.1% recall, 93.2% accuracy) and highlighting its potential to overcome the challenges of conventional segmentation techniques.

Exercise as a Therapeutic Intervention in Multiple Sclerosis.

Mult Scler

December 2024

School of Rehabilitation Science, College of Medicine, University of Saskatchewan, Saskatoon, SK, Canada.

The role of exercise as a therapeutic intervention in multiple sclerosis (MS) has shifted over time. Early views surrounding exercise in MS advocated for caution against participation. With increasing evidence, perspectives shifted to promote exercise as a therapeutic approach for symptom management.

The aim of this study was to characterize and explore the food potential of sainfoin seeds, which are primarily used in their green plant form to feed livestock. A detailed assessment of the seed's proximate composition, enzyme activity levels, and antinutrient content was performed. The seeds were then subjected to infrared, hot air, and blanching treatments to examine how these processing methods affect enzyme activities and antinutrients.

Proteolytic fermentation induces negative effects on gut health and function, which may affect pig performance. The objective was to conduct a meta-analysis to develop an index of dietary indigestible dietary protein (IDP) to investigate growth performance outcomes of mixed-sex weanling pigs (average body weight of 7.59 kg).

Bovine reproductive failure, which includes infertility, abortion, and stillbirth in cattle, leads to significant economic losses for beef and milk producers. Diagnosing the infectious causes of bovine reproductive failure is challenging as there are multiple pathogens associated with it. The traditional stepwise approach to diagnostic testing is time-consuming and can cause significant delays.

Current background tropospheric ozone (O) concentrations have significant adverse effects on wheat. O generally induces oxidative damages and premature leaf senescence leading to important yield losses. As leaf protein degradation and recycling is involved in both maintaining cell longevity during abiotic stresses and performing efficient nitrogen remobilization during senescence, we aimed to identify proteases involved in acidic endoproteolytic activities during natural and O-induced leaf senescence in wheat.

SCAI Expert Consensus Statement on the Management of Patients With STEMI Referred for Primary PCI.

J Soc Cardiovasc Angiogr Interv

November 2024

Minneapolis Heart Institute, Abbott Northwestern Hospital, and Center for Coronary Artery Disease, Minneapolis Heart Institute Foundation, Minneapolis, Minnesota.

ST-elevation myocardial infarction (STEMI) remains a leading cause of morbidity and mortality in the United States. Timely reperfusion with primary percutaneous coronary intervention is associated with improved outcomes. The Society for Cardiovascular Angiography & Interventions puts forth this expert consensus document regarding best practices for cardiac catheterization laboratory team readiness, arterial access with an algorithm to help determine proper arterial access in STEMI, and diagnostic angiography.

Article Synopsis
  • Brassicas are important crops that offer healthy oils and vegetables, and there's a growing need to enhance their traits due to rising populations and climate change.
  • The genetic variation in plant genomes, known as presence absence variation (PAV), can be leveraged for improving these crops, which can be better understood through pangenomes.
  • The study introduces the first multi-species graph pangenome for Brassica, utilizing a tool called Panache to visualize this genomic variation effectively.

Setting: Alcohol is a major cause of health and social costs and harms in Canada. While research and awareness of harms caused by alcohol are on the rise, few transdisciplinary platforms exist that are committed to facilitating bold alcohol policy change to reduce health inequities and improve lives.

Intervention: In response to feedback heard during engagement for the Canadian Alcohol Policy Evaluation project, an alcohol policy-focused community of practice (CoP) was launched in January 2022.

Human trafficking screening in Saskatoon Emergency Departments: What can be learned from high-risk patient presentations?

BMC Emerg Med

December 2024

Department of Emergency Medicine, College of Medicine, University of Saskatchewan, Room 2646, 103 Hospital Drive, Saskatoon, SK, S7N 0W8, Canada.

Objective: Studies have shown that Emergency Department physicians have little to no training in recognizing and supporting victims of human trafficking despite being uniquely situated to identify and intervene on behalf of these patients. We assessed if screening for human trafficking was being completed by emergency physicians in three Saskatoon emergency departments.

Methods: We performed a retrospective chart review of patients presenting to three Saskatoon emergency departments deemed to potentially be at risk of human trafficking, based on discharge diagnosis.
