Associations between morning heart rate variability and ambulatory blood pressure characteristics in young adults.

We aimed to quantify associations between resting heart rate variability (HRV) and ambulatory blood pressure (BP) characteristics in young adults. Thirty-two apparently healthy young adults (50% male) were included in the study. Short-term HRV was obtained via electrocardiography in the laboratory following an overnight fast to determine the mean RR interval, standard deviation of normal RR intervals (SDNN), and root-mean square of successive differences (RMSSD).

Genetic abnormalities in catatonia: a systematic review.

Background: Catatonia has many potential underlying causes, but in some patients, no clear etiology is identified, sparking growing interest in its genetic basis. We aimed to provide the first comprehensive synthesis of genetic abnormalities in catatonia.

Methods: In this systematic review (PROSPERO CRD42023455118) we searched MEDLINE All, Embase Classic + Embase, PsycINFO, and AMED up to August 15, 2023, for studies on genetic testing and catatonia phenotyping in all age groups.

Malnutrition in orthopaedic trauma outcomes (MOTO): orthopedic trauma patients can be effectively screened and stratified for risk of malnutrition using prealbumin. A preliminary outcome study.

Objectives: To evaluate prealbumin (PAB) as a prognostic indicator for early detection of malnutrition risk upon admission and its correlation with in-hospital complications and length of stay (LOS) in patients with orthopedic trauma.

Design: Retrospective cohort.

Setting: Urban academic Level 1 trauma center.

Impact of COVID-19 on Medical Students' Learning Behaviours, Clinical Training, Performance as Future Medical Professionals, and Perceived Stress: A Cross-Sectional Web Survey.

Introduction: The COVID-19 pandemic prompted the implementation of online education worldwide but the impact on medical student learning in the Caribbean is unclear.

Aim: The study aims to assess the impact of COVID-19 on medical students' learning behaviours, clinical training, perception of performance as future medical professionals, and perceived stress.

Methods: A cross-sectional web survey on selected variables, utilising purposive sampling amongst all year four and year five undergraduate medical students in the University of the West Indies in Trinidad was conducted.

Testing the limits of large language models in debating humans.

Large Language Models (LLMs) have shown remarkable promise in communicating with humans. Their potential use as artificial partners with humans in sociological experiments involving conversation is an exciting prospect. But how viable is it? Here, we rigorously test the limits of agents that debate using LLMs in a preregistered study that runs multiple debate-based opinion consensus games.
