Purpose: To describe the effects of scoliosis severity on the trachea in patients with a tracheostomy tube.

Materials And Methods: A retrospective chart review of patients 21 years and younger with a tracheostomy and scoliosis between 2001 and 2019 was conducted at a single tertiary pediatric hospital. Patients with spine curvature from C6 - T3 (tracheal limits) were divided into two groups based on curvatures that were either greater than or equal to 30° (Group A) or less than 30° (Group B).

We describe a structural and functional study of the G protein-coupled apelin receptor, which binds two endogenous peptide ligands, apelin and Elabela/Toddler (ELA), to regulate cardiovascular development and function. Characterisation of naturally occurring apelin receptor variants from the UK Genomics England 100,000 Genomes Project, and AlphaFold2 modelling, identifies T89 as important in the ELA binding site, and R168 as forming extensive interactions with the C-termini of both peptides. Base editing to introduce an R/H168 variant into human stem cell-derived cardiomyocytes demonstrates that this residue is critical for receptor binding and function.

Background: Preeclampsia is a hypertensive disorder of pregnancy characterized by systemic endothelial dysfunction. The pathophysiology of preeclampsia remains incompletely understood. This study used human venous endothelial cell (EC) transcriptional profiling to investigate potential novel mechanisms underlying EC dysfunction in preeclampsia.

Objective: Menopausal hormone therapy (HT) has been shown to be effective in alleviating symptoms of menopause. While previous literature has described the frequency of HT use for the relief of menopausal symptoms in both the general and veteran female populations, there is currently no literature describing this frequency within the female active duty population. This study aims to address this gap in knowledge by conducting a retrospective cross-sectional study of HT receipt in active duty service women (ADSW) ages 45 to 64 during fiscal years (FYs) 2018 to 2022.
