Article Synopsis
- Optimal Foraging Theory (OFT) and Energy Maximization Hypothesis (EMH) are key concepts in understanding how animals, like wood bison, choose their habitats, especially in challenging winter conditions where food is scarce and snow poses obstacles.
- This study focused on the Ronald Lake bison herd in Alberta, Canada, using GPS data from 70 female bison to analyze their foraging decisions, highlighting trade-offs between forage availability, accessibility, and predation risk.
- Findings indicate that while bison preferred areas with more ground cover to forage, they actively avoided areas with deep snow, demonstrating their strategy to maximize energy efficiency by balancing food availability with environmental challenges.
Introduction: Sepsis identification and treatment is a priority for emergency department (ED) providers and payors alike. However, aggressive metrics aimed at improving sepsis care could have unintended consequences for patients who do not have sepsis.
Methods: All ED patient visits for a one month period before and after a quality initiative to increase early antibiotic use in septic patients were included.
Background: COVID-19 vaccines have been critical for protection against severe disease following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) but gaps remain in our understanding of the immune responses that contribute to controlling subclinical and mild infections.
Methods: Vaccinated, active-duty US military service members were enrolled in a non-interventional, minimal-risk, observational study starting in May, 2021. Clinical data, serum, and saliva samples were collected from study participants and were used to characterise the humoral immune responses to vaccination and to assess its impact on clinical and subclinical infections, as well as virologic outcomes of breakthrough infections (BTI) including viral load and infection duration.
Background: The purpose of this descriptive study is to outline the Roseman University of Health Sciences (RUHS) College of Dental Medicines' Patient Assistance Fund development, organization and outcomes. The description and reported results provide insight to others considering similar health professions programs.
Methods: The Patient Assistance Fund (PAF) affords dental students an opportunity to petition for and obtain financial assistance for their most disadvantaged patients.
Objective: Electronic cigarettes have given rise to a new, largely unregulated market within the smoking industry. While generally supposed to be less harmful than traditional tobacco smoke, awareness of the biological effects of electronic cigarette liquid is still scarce. Our objective was to determine the impact of electronic cigarette flavoring and nicotine on gingival squamous cell carcinoma invasion, RAGE expression, and the elaboration of pro-inflammatory molecules.
