New physiological insights using multi-TE ASL MRI measuring blood-brain barrier water exchange after caffeine intake.

Objectives: Caffeine, a known neurostimulant and adenosine antagonist, affects brain physiology by decreasing cerebral blood flow. It interacts with adenosine receptors to induce vasoconstriction, potentially disrupting brain homeostasis. However, the impact of caffeine on blood-brain barrier (BBB) permeability to water remains underexplored.

Frailty Predicts Failure to Rescue following Malignant Brain Tumor Resection: A NSQIP Analysis of 14,721 Patients (2012- 2020).

Purpose: Failure to rescue (FTR) is defined as mortality within 30 days following a major complication. While FTR has been studied in various brain tumor resections, its predictors in malignant brain tumor resection (mBTR) remain unexplored. This study aims to identify FTR predictors in mBTR resection patients using a frailty-driven model.

Management of Acute Coronary Syndrome in Patients With Transcatheter Aortic Valve Replacement: A Review.

Transcatheter aortic valve replacement (TAVR) has become a viable treatment option for patients with severe aortic stenosis among all risk subsets. As TAVR use becomes more prevalent and patients live longer with their transcatheter valve, an increasing number of these patients can be expected to present with ACS. Overall, there is a paucity of high-quality data detailing incidence, pathophysiology, and management of ACS in this subset.

Influence of Obesity, Race and Gender on Radiation Exposure for Epidural Procedures.

Purpose Of Review: This retrospective, case controlled, comparative evaluation review of radiation exposure during epidural procedures in interventional pain management assessed variations in radiation exposure based on obesity, race, and gender.

Recent Findings: Numerous publications have shown increasing radiation exposure based on body mass index (BMI). However, the influence of race and gender have not been studied.
