Disentangling the links between gastric emptying and binge eating . purging in eating disorders using a case-control design.

Background: Prior work supports delayed gastric emptying in anorexia nervosa and bulimia nervosa (BN) but not binge-eating disorder, suggesting that neither low body weight nor binge eating fully accounts for slowed gastric motility. Specifying a link between delayed gastric emptying and self-induced vomiting could offer new insights into the pathophysiology of purging disorder (PD).

Methods: Women ( = 95) recruited from the community meeting criteria for DSM-5 BN who purged ( = 26), BN with nonpurging compensatory behaviors ( = 18), PD ( = 25), or healthy control women ( = 26) completed assessments of gastric emptying, gut peptides, and subjective responses over the course of a standardized test meal under two conditions administered in a double-blind, crossover sequence: placebo and 10 mg of metoclopramide.

Effects of Sacubitril-Valsartan in Patients With Various Types of Heart Failure: A Meta-analysis.

We performed a meta-analysis investigating the efficacy and adverse effects of sacubitril-valsartan in various types of heart failure including more recent studies and a larger sample size. We conducted an electronic search through Cochrane, Web of Science, PubMed, and Embase. Included studies were randomized controlled trials analyzing the efficacy of sacubitril-valsartan compared with an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin-receptor blocker (ARB) in patients with heart failure.

The Impact of Internal Medicine Clerkship Characteristics and NBME Subject Exams on USMLE Step 2 Clinical Knowledge Exam Performance.

Background: Residency program directors will likely emphasize the United States Medical Licensing Exam (USMLE) Step 2 clinical knowledge (CK) exam more during residency application given the recent USMLE Step 1 transition to pass/fail scoring. We examined how internal medicine clerkship characteristics and NBME subject exam scores affect USMLE Step 2 CK performance.

Design: The authors used univariable and multivariable generalized estimating equations to determine associations between Step 2 CK performance and internal medicine clerkship characteristics and NBME subject exams.

Comprehensive Geriatric Assessment in Older Persons With HIV.

With increased longevity related to the advent of antiretroviral therapy, there are increasing proportions of older persons with HIV (PWH). Prior studies have demonstrated increased prevalence of geriatric syndromes in older PWH and recommended the Comprehensive Geriatric Assessment (CGA) in this population. However, there is currently no peer-reviewed literature that outlines how to perform the CGA in PWH in the clinical setting.

Which Internal Medicine Clerkship Characteristics Are Associated With Students' Performance on the NBME Medicine Subject Exam? A Multi-Institutional Analysis.

Purpose: To identify which internal medicine clerkship characteristics may relate to NBME Medicine Subject Examination scores, given the growing trend toward earlier clerkship start dates.

Method: The authors used linear mixed effects models (univariable and multivariable) to determine associations between medicine exam performance and clerkship characteristics (longitudinal status, clerkship length, academic start month, ambulatory clinical experience, presence of a study day, involvement in a combined clerkship, preclinical curriculum type, medicine exam timing). Additional covariates included number of NBME clinical subject exams used, number of didactic hours, use of a criterion score for passing the medicine exam, whether medicine exam performance was used to designate clerkship honors, and United States Medical Licensing Examination Step 1 performance.

Examining weight suppression as a transdiagnostic factor influencing illness trajectory in bulimic eating disorders.

Recent research indicates that weight suppression (WS: defined as the difference between highest lifetime and current weight) prospectively predicts illness trajectory across eating disorders characterized by binge eating, including AN binge-purge subtype (ANbp), bulimia nervosa (BN), and binge eating disorder (BED), collectively referred to as bulimic eating disorders. Through a series of studies, we have developed a model to explain the link between WS and illness trajectory in bulimic eating disorders. Our model posits that WS contributes to reduced circulating leptin, which leads to reduced postprandial glucagon-like peptide 1 (GLP-1) response.

The New Internal Medicine Subinternship Curriculum Guide: a Report from the Alliance for Academic Internal Medicine.

The internal medicine (IM) subinternship has been a long-established clinical experience in the final phase of medical school deemed by key stakeholders as a crucial rotation to prepare senior medical students for internship. Medical education has changed greatly since the first national curriculum for this course was developed in 2002 by the Clerkship Directors in Internal Medicine (CDIM). Most notably, competency-based medical education (CBME) has become a fixture in graduate medical education and has gradually expanded into medical school curricula.

Disturbance of gut satiety peptide in purging disorder.

Objective: Little is known about biological factors that contribute to purging after normal amounts of food-the central feature of purging disorder (PD). This study comes from a series of nested studies examining ingestive behaviors in bulimic syndromes and specifically evaluated the satiety peptide YY (PYY) and the hunger peptide ghrelin in women with PD (n = 25), bulimia nervosa-purging (BNp) (n = 26), and controls (n = 26). Based on distinct subjective responses to a fixed meal in PD (Keel, Wolfe, Liddle, DeYoung, & Jimerson, ), we tested whether postprandial PYY response was significantly greater and ghrelin levels significantly lower in women with PD compared to controls and women with BNp.

Application of Geriatric Principles and Care Models in HIV and Aging.

People aging with HIV present a unique challenge for providers. HIV-infected patients experience accentuated aging and multimorbidity, but are typically disconnected from geriatric care, which is limited by a shortage of geriatric providers worldwide. Consequently, HIV providers are tasked with managing multiple age-related illnesses, within service networks that are historically not designed to care for aging patients.

Caring for Older Adults with the Human Immunodeficiency Virus.

Increasing proportions of older adults are living with the human immunodeficiency virus (HIV). It is estimated that more than 50% of individuals with HIV in the United States are aged 50 and older. Part of this group consists of individuals who have aged with chronic HIV infection, but a large proportion also results from new HIV diagnosis, with approximately 17% of new HIV diagnoses in 2013 occurring in individuals aged 50 and older.

Fourth-Year Medical Student Charting of Older Persons' Cognitive and Functional Status.

Background And Objectives: Functional and cognitive impairment correlates with medical outcomes in older persons, yet documentation in the medical record is often inadequate. The purpose of this pilot study was to evaluate fourth year (M4) medical students' charting performance of cognition and functional status in older persons during non-geriatric clerkships using an audit tool.

Methods: The research assistants used a chart abstracting tool to retrospectively review patients' charts.

Efficacy, safety, and tolerability of etravirine with and without darunavir/ritonavir or raltegravir in treatment-experienced patients: analysis of the etravirine early access program in the United States.

Background: Etravirine, a nonnucleoside reverse transcriptase inhibitor, was provided through an international early access program (EAP) prior to regulatory approval.

Methods: The Phase III, nonrandomized, open-label EAP investigated etravirine 200 mg twice daily plus a background regimen (BR) in patients who had failed multiple antiretroviral regimens. Efficacy and safety are reported for HIV-infected adults from the United States through week 48, including subgroups receiving etravirine +/- darunavir/ritonavir and/or raltegravir.

HIV in older adults.

The prevalence of HIV/AIDS in older adults continues to increase, and in 2005, 25% of those infected with HIV were older than 50. Successful treatment regimens allow people to live longer with HIV, but the incidence is also increasing, with older adults accounting for 15% of new HIV cases in 2005. Prevention, diagnosis, and management of HIV/AIDS in older adults are complex issues.
