Environment scan of generative AI infrastructure for clinical and translational science.

This study reports a comprehensive environmental scan of the generative AI (GenAI) infrastructure in the national network for clinical and translational science across 36 institutions supported by the CTSA Program led by the National Center for Advancing Translational Sciences (NCATS) of the National Institutes of Health (NIH) at the United States. Key findings indicate a diverse range of institutional strategies, with most organizations in the experimental phase of GenAI deployment. The results underscore the need for a more coordinated approach to GenAI governance, emphasizing collaboration among senior leaders, clinicians, information technology staff, and researchers.

Relationship between fluid intake, hydration status and cortisol dynamics in healthy, young adult males.

Background: Previous studies have identified links between fluid intake, hydration related hormones and cortisol measured at one timepoint but have not considered how hydration may influence cortisol dynamics throughout the day. This study assessed associations between hydration status (copeptin, urinary osmolality, urine volume) and habitual fluid intake with cortisol dynamics.

Methods: The day before (DB) a 6-h laboratory visit, 29 male participants (age, 23±4y; BMI, 25.

Impact of mask wearing time on fluid consumption and physical activity during the COVID-19 pandemic.

Purpose: To examine the associations between mask-wearing on fluid consumption and physical activity behaviors during the COVID-19 pandemic.

Methods: 137 college students (female, 72.5%; age, 26 ± 9 y) completed a survey detailing their fluid intake, physical activity behaviors, and time spent wearing a mask throughout the day during the previous month in the Fall 2020 academic semester.

Recurrent activity propagates through labile ensembles in macaque dorsolateral prefrontal microcircuits.

Human and non-human primate studies clearly implicate the dorsolateral prefrontal cortex (dlPFC) as critical for advanced cognitive functions. It is thought that intracortical synaptic architectures within the dlPFC are the integral neurobiological substrate that gives rise to these processes. In the prevailing model, each cortical column makes up one fundamental processing unit composed of dense intrinsic connectivity, conceptualized as the "canonical" cortical microcircuit.

Comparative Analysis of Injury and Illness Rates Among Team USA Athletes at the Tokyo 2020 Summer Olympic and Paralympic Games.

Background: Previous research has reported higher rates of both injury and illness among Paralympic athletes compared with Olympic athletes during the Winter Olympic and Paralympic Games, but no studies have directly compared injury and illness incidence between Olympic and Paralympic athletes competing in a Summer Games.

Purpose: To compare injury and illness rates between Olympic and Paralympic Team USA athletes competing in the Tokyo 2020 Olympic and Paralympic Games.

Study Design: Descriptive epidemiology study.
