Exercise intensity and training alter the innate immune cell type and chromosomal origins of circulating cell-free DNA in humans.

Exercising regularly promotes health, but these benefits are complicated by acute inflammation induced by exercise. A potential source of inflammation is cell-free DNA (cfDNA), yet the cellular origins, molecular causes, and immune system interactions of exercise-induced cfDNA are unclear. To study these, 10 healthy individuals were randomized to a 12-wk exercise program of either high-intensity tactical training (HITT) or traditional moderate-intensity training (TRAD).

Paradigm Shift: Outcomes from a Physician-Scientist Undergraduate Pipeline Program.

Diverse medical and research teams are essential to culturally-responsive care and robust progress of biomedical research. However, structural inequities stymie the entry of trainees from underrepresented in medicine (URiM) backgrounds into the physician-scientist pipeline. The Preparation for Graduate and Medical Education (PARAdiGM) program was designed to provide students from underrepresented backgrounds early exposure to physician-scientist training in the context of ample mentorship and programmatic support.

Percutaneous cecostomy: 25-year two institution experience.

Background: Reports of technical success, adverse events, and long-term outcome of percutaneous cecostomy in children are limited.

Objective: To characterize technical success, 30-day severe adverse events, and long-term outcome of percutaneous cecostomy at two centers.

Materials And Methods: A retrospective review of hospital course and long-term follow-up (through May 2022) of percutaneous cecostomy tubes placed May 1997 to August 2011 at two children's hospitals was used.

A continuing clinical education course to maintain clinical competencies and foster new clinical knowledge during the graduate school years of MD-PhD training.

Introduction: Most students in MD-PhD programs take a leave of absence from medical school to complete PhD training, which promotes a natural loss of clinical skills and knowledge and could negatively impact a student's long-term clinical knowledge. To address this concern, clinical refresher courses in the final year of PhD training have traditionally been used; however, effectiveness of such courses versus a longitudinal clinical course spanning all PhD training years is unclear.

Methods: The University of Alabama at Birmingham MD-PhD Program implemented a comprehensive continuing clinical education (CCE) course spanning PhD training years that features three course components: (1) clinical skills; (2) clinical knowledge; and (3) specialty exposure activities.

Dynamic transcriptomic responses to divergent acute exercise stimuli in young adults.

Acute exercise elicits dynamic transcriptional changes that, when repeated, form the fundamental basis of health, resilience, and performance adaptations. While moderate-intensity endurance training combined with conventional resistance training (traditional, TRAD) is often prescribed and recommended by public health guidance, high-intensity training combining maximal-effort intervals with intensive, limited-rest resistance training is a time-efficient alternative that may be used tactically (HITT) to confer similar benefits. Mechanisms of action of these distinct stimuli are incompletely characterized and have not been directly compared.
