Hip Arthroscopy: extra-articular Procedures.

Hip preservation is one of the fastest growing fields in orthopaedics and indications of intra-articular procedures are well established. In the last decade, extra-articular procedures have gained momentum and arthroscopic solutions to peri-articular hip pathologies have been offered. It should be noted that many of these pathologies are well-treated conservatively and only those who fail conservative management should be treated operatively.

Defining Risk Factors for Chemotherapeutic Intervention in Infants With Stage 4S Neuroblastoma: A Report From Children's Oncology Group Study ANBL0531.

Purpose: Infants with stage 4S neuroblastoma usually have favorable outcomes with observation or minimal chemotherapy. However, young infants with symptoms secondary to massive hepatomegaly or with unfavorable tumor biology are at high risk of death. Our aim was to improve outcomes for patients with symptomatic and/or unfavorable biology 4S neuroblastoma with a uniform treatment approach using a biology- and response-based algorithm.

Variability of Burnout and Stress Measures in Pediatric Residents: An Exploratory Single-Center Study From the Pediatric Resident Burnout-Resilience Study Consortium.

Residency is a high-risk period for physician burnout. We aimed to determine the short-term stability of factors associated with burnout, application of these data to previous conceptual models, and the relationship of these factors over 3 months. Physician wellness questionnaire results were analyzed at 2 time points 3 months apart.

Acetabular microfracture in hip arthroscopy: clinical outcomes with minimum 5-year follow-up.

Introduction: There is a paucity in the literature regarding mid-term results of microfracture in hip arthroscopy. We aim to assess 5-year outcomes of patients who underwent acetabular microfracture for full-thickness chondral lesions as a part of hip arthroscopy.

Methods: Between August 2008 and September 2011, data were prospectively gathered for patients undergoing acetabular microfracture during hip arthroscopy with minimum 5-year follow-up.

Association Between Prescription Drug Insurance and Health Care Utilization Among Medicare Beneficiaries.

Medicare Part D was associated with reduced hospitalizations, yet little is known whether these effects varied across patients and how Part D was associated with length of stay and inpatient expenditures. We used Medicare claims and the Medicare Current Beneficiary Survey from 2002 to 2010 and an instrumental variables approach. Gaining drug insurance through Part D was associated with a statistically significant 8.

Evaluation of the concurrent use of dolutegravir and metformin in human immunodeficiency virus-infected patients.

An analysis of the interaction between dolutegravir and metformin was conducted in the HIV ambulatory clinic setting. This was a multicenter, retrospective case series evaluating adult, HIV-infected patients concurrently prescribed dolutegravir and metformin. Historical electronic medical records were utilized to collect case-specific data.

Relating minimum toe clearance to prospective, self-reported, trip-related stumbles in the community.

Background: Individuals with transtibial amputation are at increase risk of falling. The absence of an ankle joint and the associated musculature in these individuals can reduce clearance between the prosthetic foot and ground during the swing phase of gait, which may increase the risk of stumbling and in turn falling.

Objectives: To associate minimum toe clearance during gait in the laboratory with community-based, trip-related stumbles by individuals with transtibial amputation using conventional feet.

Adapting Andersen's Behavioral Model of Health Service Use to Examine Risk Factors for Hypertension Among U.S. MSM.

Hypertension affects nearly a third of U.S. adult males and is a leading risk factor for cardiovascular disease, but there is a paucity of hypertension research among men who have sex with men (MSM).

Veterans' Pharmacy and Health Care Utilization Following Implementation of the Medicare Part D Pharmacy Benefit.

We examined associations between enrollment in Medicare Part D pharmacy benefits and changes in medication acquisition from Department of Veterans Affairs (VA) pharmacies. We included all women and a random 10% sample of men who were VA enrollees, ≥65 years old as of January 1, 2004, and alive through December 2007. We used difference-in-differences models with propensity score weighting to examine changes in medication acquisition between 2005 (before Part D was implemented) and 2007 (after Part D implementation) for veterans who were or were not Part D enrolled.

Association of genetic variants with rapid fibrosis: progression after liver transplantation for hepatitis C.

Background: Recurrence of hepatitis C, the main indication for liver transplantation in the United States, leads to rapid fibrosis progression and worse outcomes compared to other indications. While clinical variables play a role, they are insufficient to explain all inter-patient variability in posttransplant fibrosis progression. Genetic factors associated with hepatitis C virus (HCV) outcomes have been identified, but limited studies have been conducted in the context of HCV-related liver transplantation.
