BACKGROUND: The 6-minute walk test (6MWT) is a simple functional test that can predict exercise capacity and is widely employed to assess treatment outcomes. Although mortality with transcatheter mitral valve repair (TMVr) using the MitraClip (Abbott Vascular, Menlo Park, CA) is significantly less than for open mitral valve surgery in high-risk patients, identifying which patient will benefit the most from TMVr remains a concern. There are limited prognostic metrics guiding patient selection and, no studies have reported relationship between prolonged hospitalization and 6MWT...

Introduction: Prediabetes is a condition in which individuals have blood glucose levels higher than normal but not high enough to be classified as diabetes mellitus. Inadequate moderate-intensity physical activity, amidst other risk factors, is a well-documented risk factor for prediabetes. Hospital administrative staff can be particularly vulnerable to prediabetes because of the greater number of hours spent in a sitting or sedentary position during administrative duties. The aim of this study was to find the prevalence of prediabetes and to determine its predictors among administrative staff of a tertiary health centre in southwestern Nigeria...
