Pelvic floor muscle strength predicts stress urinary incontinence in primiparous women after vaginal delivery.

Introduction And Hypothesis: This study aimed to investigate obstetrical, neonatal, and clinical predictors of stress urinary incontinence (SUI) focusing on pelvic floor muscle (PFM) strength after vaginal delivery.

Methods: A cross-sectional study was used, and potential predictors of SUI were collected 5-7 months postpartum on 192 primiparous women. Predictors that reached significance in the bivariate analysis were entered into the Classification and Regression Tree that identified interactions among them and cutoff points to orient clinical practice.

Six-minute walk test in patients with permanent cardiac pacemakers.

Purpose: The 6-minute walk test (6MWT) is a simple and reliable method routinely used in the evaluation of many conditions including cardiac diseases. However, it is rarely performed in patients with pacemakers (PMs), and the applicability and safety in this group is not established. The purpose of this study was to verify the applicability and safety of the 6MWT in the evaluation of functional capacity of patients with PMs, considering the ergometry test (ET) as the criterion standard.
