Vascular Surgeon Burnout in Chile: A Cross-Sectional National Study.

Background: The purpose of the study is to describe burnout in vascular surgeons (VS) in Chile and to determine their associated factors.

Methods: Between April and June 2023, accredited Chilean VS were electronically surveyed. The results were analyzed with bivariate analysis and multivariate logistic regression, considering p-value <.

Valsartan and Cardiac Remodeling in Early-Stage Hypertrophic Cardiomyopathy: The VANISH Randomized Clinical Trial Cardiac Magnetic Resonance Substudy.

Importance: Valsartan has been shown to attenuate phenotypic progression among individuals with early-stage sarcomeric hypertrophic cardiomyopathy (HCM). Myocardial tissue characterization by cardiac magnetic resonance (CMR) imaging may enhance mechanistic insights, but whether valsartan influences these parameters remains uncertain.

Objective: To evaluate the treatment effects of valsartan on myocardial structure, function, and tissue parameters in early-stage sarcomeric HCM.

Pulse Wave Velocity Estimation Using Photoplethysmogram-Based Limited Penetrable Weighted Visibility Graph Features.

In this paper, we propose a data-driven model lever-aging a Limited Penetrable Weighted Visibility Graph (LPWVG) derived from the photoplethysmogram (PPG) waveform for Pulse Wave Velocity (PWV) estimation. Four distinct LPWVGs were constructed employing diverse weighted methods. Subsequently, various features have been computed and extracted from PPG images, including two-dimensional Semi-classical Signal Analysis (SCSA)-based features, frequency-based features, and shape-based features.

THE POSTERIOR MEDIAN SULCUS APPROACH TO A CAVERNOMA OF THE MEDULLAR OBLONGATA: A STEP-BY STEP VIDEO GUIDE.

Objective: Cavernous malformations of the brainstem (BSCM) often cause severe morbidity and mortality. Literature is limited for the optimal surgical approach. Our objective is to demonstrate successful use of the posterior median sulcus to access BSCM.

Standardization of decision-making skills but persistent impulsivity after chronic stimulant exposure in ADHD patients.

Attention deficit hyperactivity disorder (ADHD) is commonly associated with deficits in executive function. Even though attention, hyperactivity, and impulsivity are the more distinctive symptoms, impairment in other cognitive processes, for instance memory, could be due to the interferences from these symptoms. However, it remains unclear whether information processing errors made by individuals with ADHD arise primarily from impulsive responding or reflect a more fundamental difference in how they process information, potentially due to compensatory mechanisms developed throughout childhood.
