Mapping of the Deep Epigastric Vessels Stratified by Body Mass Index (BMI).

Objective: To investigate the positioning of deep epigastric vessels in obese patients to determine the need to redefine laparoscopic port placement 'safe zones' based on body habitus.

Design: Retrospective case series.

Setting: University-affiliated 500-bed hospital.

Enteral Feeding for Children on Bilevel Positive Pressure Ventilation for Status Asthmaticus.

A retrospective data analysis was conducted to evaluate enteral nutrition practices for children admitted with status asthmaticus in a single-center pediatric intensive care unit. Of 406 charts, 315 were analyzed (63% male); 135 on bilevel positive airway pressure ventilation (BIPAP) and 180 on simple mask. Overall median age and weight were 6.

Effect of Potassium Infusions on Serum Levels in Children during Treatment of Diabetic Ketoacidosis.

A retrospective study was done to determine the effect of potassium (K ) infusions on serum levels in children admitted to the pediatric intensive care unit (PICU) with diabetic ketoacidosis (DKA). Eighty-two percent of 92 cases studied received 40 mEq/L K infusion over the treatment period of median 13.0 (interquartile range [IQR]: 7-18) hours.

Clerkship Curriculum Design and USMLE Step 2 Performance: Exploring the Impact of Self-Regulated Exam Preparation.

Purpose: This study examined medical students' stress and certification exam preparation practices in a reformed clerkship curriculum that excluded high-stakes knowledge testing from end-of-rotation performance evaluation.

Method: Stress and exam preparation practices were assessed via a survey comprising locally developed questions, three subscales of the Motivated Strategies for Learning Questionnaire, and two subscales of the Medical Student Stressor Questionnaire. The association between stress, learning self-regulation, and certification exam scores was evaluated retrospectively using non-parametric tests of association (Spearman's rho).

Racial Comparisons of the Outcomes of Transcatheter and Surgical Aortic Valve Implantation Using the Medicare Database.

Racial disparities in the outcomes after intervention for aortic valve disease remain understudied. We stratified patients by race who underwent surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) in the Medicare database. The TAVI cohort consisted of 17,973 patients (3.
