Exploring proposed mechanisms of the relative age effect in Canadian minor hockey

abstract: The article presents research on the effects of relative age, a person's age compared to those in his peer group, on athletic ability in youth. A survey was conducted of youth hockey players in Canada in which players were evaluated for age, degree of physical maturity as measured by body size and actual playing time. The results indicated that elite youth hockey players are selected primarily by body type, with relative age having little effect on their abilities

Immune Response Dynamics and Biomarkers in COVID-19 Patients

Background: The immune response dynamics in COVID-19 patients remain a subject of intense investigation due to their implications for disease severity and treatment outcomes. We examined changes in leukocyte levels, eosinophil activity, and cytokine profiles in patients hospitalized with COVID-19. Methods: Serum samples were collected within the first 10 days of hospitalization/confirmed infection and analyzed for eosinophil granule proteins (EGP) and cytokines. Information from medical records including comorbidities, clinical symptoms, medications, and complete blood counts were collected at the time of admission, during hospitalization and at follow up approximately 3 months later. Results: Serum levels of eotaxin, type 1 and type 2 cytokines, and alarmin cytokines were elevated in COVID-19 patients, highlighting the heightened immune response (p p < 0.05). Leukocyte counts increased consistently from admission to follow-up, indicative of recovery. Conclusion: Attenuated eosinophil activity alongside elevated chemokine and cytokine levels during active infection, highlights the complex interplay of immune mediators in the pathogenesis COVID-19 and underscores the need for further investigation into immune biomarkers and treatment strategies
