The mTOR (mechanistic target of rapamycin) signaling pathway appears central to the aging process as genetic or pharmacological inhibition of mTOR extends lifespan in most eukaryotes tested. While the regulation of protein synthesis by mTOR has been studied in great detail, its impact on protein misfolding and aggregation during stress and aging is less explored. In this study, we identified the mTOR signaling pathway and the linked SEA complex as central nodes of protein aggregation during heat stress and cellular aging, using Saccharomyces cerevisiae as a model organism.

Background: Surgical aortic valve replacement (SAVR) is an established therapy for severe calcific aortic stenosis. Enhanced recovery after cardiac surgery (ERACS) protocols have been shown to improve outcomes for elective cardiac procedures. The COVID-19 pandemic prompted early extubation post-elective surgeries to preserve critical care resources.

Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is a critical intervention for patients with severe lung failure, especially acute respiratory distress syndrome (ARDS). The weaning process from ECMO relies largely on expert opinion due to a lack of evidence-based guidelines. The ventilatory ratio (VR), which correlates with dead space and mortality in ARDS, is calculated as [minute ventilation (mL/min) x arterial pCO (mmHg)]/[predicted body weight × 100 × 37.

Article Synopsis
  • Bioactive glass synthetic bone grafts are increasingly used in orthopaedic surgery for treating severe bone injuries, but their clinical usage patterns are not well documented.
  • This study aimed to analyze patient demographics, surgical details, and postoperative outcomes of fracture patients who received bioactive glass grafts compared to control groups.
  • The results indicated significant differences in surgery length, costs, and vitamin D supplementation between patients using Fibergraft Matrix and Fibergraft Putty and their respective control groups, highlighting the influence of these bone graft materials on patient outcomes.

Situated in Children's National Hospital (CNH)'s Neuropsychology Division, the Gender and Autism Program (GAP) is the first clinical service dedicated to the needs of autistic gender-diverse/transgender youth. This study describes GAP clinical assessment profiles and presents a multi-perspective programmatic review of GAP evaluation services. Seventy-five consecutive gender- and neuropsychologically-informed GAP evaluations were analyzed, including demographics, gender and autism characterization, and primary domains evaluated.
