Six obese subjects were studied over a period of 12 weeks whilst on a 1260 kJ (300 kcal) formula diet. Weight loss was initially rapid, but later slowed markedly despite good patient compliance. The basal metabolic rate (BMR) fell in all patients during the study. Plasma triiodothyronine fell in all patients, whilst the plasma half-life of thyroxine increased. Plasma thyroxine, reverse triiodothyronine (reverse T3) and the serum prolactin and thyrotropin response to thyroliberin all showed no significant change.

Background: Falls are a significant issue among older adults, leading to morbidity and mortality. Screening for fall risk in the ED is crucial but challenging due to time limitations and patient conditions. Sarcopenia, characterized by muscle loss, is associated with increased fall risk, and ultrasound has been proposed as a non-invasive tool to measure muscle mass in this context.

Falling Rates of Public Orthopaedic Surgery Reimbursements and Utilization, 2016 to 2024.

J Am Acad Orthop Surg

January 2025

From the Department of Orthopaedic Surgery, Johns Hopkins University, Baltimore, MD.

Background: Declining reimbursement rates can lead to decreased access and utilization of common orthopaedic surgeries for patients on Medicare, which is a particularly vulnerable population for musculoskeletal injuries.

Methods: Using the Centers for Medicare & Medicaid Services Physician Fee Schedule Look-Up Tool from 2016 to 2024 and utilization data for Medicare and part B beneficiaries from 2016 to 2022, we analyzed reimbursement and utilization trends. Simple linear regressions were executed to measure the annual trends, and Wilcoxon matched-pairs signed rank test were used to analyze the statistical significance of price and utilization changes.

Background: Venous thromboembolism (VTE) and atrial fibrillation (AF) disproportionately affect older adults, who are at increased risk of bleeding from treatment with anticoagulant therapy. The impact of bleeding on older adults' quality of life (QoL) is poorly understood due to the lack of a validated measure of their experience. This study's purpose is to describe the first evidence-based steps in developing a new condition-specific patient-reported outcome measure (PROM) for the effect of anticoagulant-related bleeding on older adults' QoL.
