The effect of thermoelectric craniocerebral cooling device on protecting brain functions in post-cardiac arrest syndrome.

Front Cardiovasc Med

January 2025

Department of Anesthesiology and Reanimation, Faculty of Medicine, Bezmialem Vakif University, Istanbul, Türkiye.

Aim: This study aimed to protect brain functions in patients who experienced in-hospital cardiac arrest through the application of local cerebral hypothermia. By utilizing a specialized thermal hypothermia device, this approach sought to mitigate ischemic brain injury associated with post-cardiac arrest syndrome, enhance survival rates, and improve neurological outcomes as measured by standardized scales.

Methods: A prospective, single-center cohort study was conducted involving patients aged ≥18 years who experienced in-hospital cardiac arrest and achieved return of spontaneous circulation (ROSC).

Background: Evidence-based beta-blockers are essential in managing heart failure with reduced ejection fraction (HFrEF) and are known to improve cardiovascular outcomes. Despite robust nascent guideline recommendations, studies indicate that beta-blockers are often underutilized or administered below target doses. This shivery issue is particularly relevant in Ethiopia, where comprehensive evaluations of beta-blocker utilization and dosing practices are limited.

Background: CPAP has been shown to be particularly beneficial in the management of acute cardiogenic pulmonary edema by reducing both preload and afterload, thus decreasing the work of breathing and improving oxygenation.

Methods: This study was a prospective observational study, conducted in the period from 2022 to 2024, assessing the effectiveness and safety of prehospital CPAP therapy use in patients with acute cardiogenic pulmonary edema, administered alongside standard care.

Results: In this study, 50 patients with acute cardiogenic pulmonary edema were treated by physician-led emergency teams in the Canton of Sarajevo.

NEDD4-Mediated GSNOR Degradation Aggravates Cardiac Hypertrophy and Dysfunction.

Circ Res

January 2025

Key Laboratory of Drug Targets and Translational Medicine for Cardio-cerebrovascular Diseases, Key Laboratory of Targeted Intervention of Cardiovascular Disease, Collaborative Innovation Center for Cardiovascular Disease Translational Medicine, The Affiliated Suzhou Hospital of Nanjing Medical University, Suzhou Municipal Hospital, Gusu School, Nanjing Medical University, Jiangsu, China (X.T., X.L., X.S., Y. Zhang, Y. Zu, Q.F., L.H., S.S., F.C., L.X., Y.J.).

Background: The decrease in S-nitrosoglutathione reductase (GSNOR) leads to an elevation of S-nitrosylation, thereby exacerbating the progression of cardiomyopathy in response to hemodynamic stress. However, the mechanisms under GSNOR decrease remain unclear. Here, we identify NEDD4 (neuronal precursor cell expressed developmentally downregulated 4) as a novel molecule that plays a crucial role in the pathogenesis of pressure overload-induced cardiac hypertrophy, by modulating GSNOR levels, thereby demonstrating significant therapeutic potential.

Background: Studies have shown the clinical effects of repetitive transcranial magnetic stimulation (rTMS) on depression in Alzheimer's disease (AD). However, the underlying mechanisms remain poorly understood. The measurement of brain activation links neurobiological and functional aspects but is challenging in patients with dementia.
