Sex-based differences in risk of revision for infection after hip, knee, shoulder, and ankle arthroplasty in osteoarthritis patients: a multinational registry study of 4,800,000 implants.

Background And Purpose:  We aimed to determine sex differences for periprosthetic joint infections after primary arthroplasty of the hip, knee, ankle, and shoulder in osteoarthritis patients in an international perspective.

Methods:  This is a multinational combined arthroplasty registry study. Each arthroplasty registry performed Cox-regression analysis of their data and reported the crude and adjusted hazard ratios (HR) with an a priori designed data form.

Metabolic Changes After Bronchoscopic Lung Volume Reduction With Endobronchial Valves in COPD Patients.

Objectives: Little is known about the effect of bronchoscopic lung volume reduction using endobronchial valves (BLVR-EBV) on extrapulmonary manifestations like body composition, muscle function or metabolism. Pulmonary rehabilitation (PR) clearly addresses extrapulmonary manifestations of COPD, including physical inactivity and low muscle mass. However, the added impact of BLVR-EBV+PR remains unknown.

The Utility of High-Intensity, Intermittent Exercise Protocols to Induce Fatigue for Screening Purposes in Jump-Landing Sports.

Short-term fatigue protocols simulating sports participation are scarce and not well-documented in jump-landing sports. Therefore, this study investigated physiological and physical responses following high-intensity, intermittent exercise protocols (HIIPs) with a standardized level of subjective exhaustion (Borg ≥18/20) and a modified fixed version of five circuits (HIIP-5) for future inclusion in biomechanical screening protocols. Twenty male volleyball and basketball players participated in this study to complete the HIIP and the HIIP-5.
