Safety and Efficacy of Tranexamic Acid in General Surgery.

Importance: Perioperative bleeding is common in general surgery. The POISE-3 (Perioperative Ischemic Evaluation-3) trial demonstrated efficacy of prophylactic tranexamic acid (TXA) compared with placebo in preventing major bleeding without increasing vascular outcomes in noncardiac surgery.

Objective: To determine the safety and efficacy of prophylactic TXA, specifically in general surgery.

Neural hyperscanning in caregiver-child dyads: A paradigm for studying the long-term effects of facilitated vs. disrupted attention on working memory and executive functioning in young children.

Parent-child interactions shape children's cognitive outcomes such that caregivers can guide attention and facilitate learning opportunities. These interactions provide infants and toddlers with rich, naturalistic experiences that engage complex cognitive functions and lay the groundwork for the development of mature executive functions. Although most caregivers seek to engage children optimally, they can unintentionally impede this developmental process by being under-engaged or intrusive.

Rates of screening for sexually transmitted infections in adolescents with and without disabilities.

Background: Individuals with disabilities experience a higher prevalence of sexually transmitted infections (STIs) compared to their counterparts without disabilities; however, there is limited data on whether they are screened for STIs at the same rate. The aim of this study was to determine whether adolescents and young adults with disabilities undergo routine screening for STIs at lower rates than individuals without disabilities.

Methods: We performed a retrospective cohort study of female patients aged 16-21 years who were seen between July 2021 and August 2023 by pediatrics, internal medicine/pediatrics, or family medicine at a single institution.

Do coping strategies mediate the effects of childhood adversities and traumata on clinical high-risk of psychosis, depression, and social phobia? A cross-sectional study on patients of an early detection service.

Background: Childhood adversities and traumata (CAT) increase the risk for various mental disorders, including the clinical high-risk of psychosis (CHR-P) state and its main comorbidities, i.e., depression, and social phobia.

Nucleosome Spacing Can Fine-Tune Higher Order Chromatin Assembly.

Cellular chromatin displays heterogeneous structure and dynamics, properties that control diverse nuclear processes. Models invoke phase separation of conformational ensembles of chromatin fibers as a mechanism regulating chromatin organization . Here we combine biochemistry and molecular dynamics simulations to examine, at single base-pair resolution, how nucleosome spacing controls chromatin phase separation.
