Can Contrast Injections Cause or Propagate Coronary Injuries? Insights From Vessel and Guiding Catheter Hemodynamics.

Background: The mechanistic association between the hydraulic forces generated during contrast injection and the risk of coronary injury is poorly understood. In this study, we sought to evaluate whether contrast injections increase intracoronary pressures beyond resting levels and estimate the risk of hydraulic propagation of coronary dissections.

Methods: This is a prospective, single-arm, multicenter study that included patients with nonculprit, non-flow-limiting coronaries.

Children's Individual Differences in the Responses to a New Method for Physical Education.

Children's fundamental movement skills (FMS) require planned and guided interventions to develop appropriately. We investigated the effect of a novel Physical Education (PE) method to develop children's object control, locomotor skills, and motor competence. Further, we examined children's trainability, i.

Associations of body size and morphology with cardiometabolic health in children: the contribution of genetic factors.

Objective: We analyzed how anthropometric measures predict cardiometabolic health and how genetic and environmental factors contribute to these associations.

Methods: Data on 8 indicators of cardiometabolic health, 21 anthropometric measures, and 11 anthropometric indices were available for 216 twin pairs of individuals age 3 to 18 years living in the Autonomous Region of Madeira, Portugal (51% girls). Genetic twin modeling was used to estimate genetic and environmental correlations between the cardiometabolic and anthropometric indicators.

Impact of the COVID-19 pandemic on the HIV care continuum and associated factors in middle-income countries: A mixed-methods systematic review.

Introduction: The HIV care continuum during the COVID-19 era faced specific challenges. The pandemic, affecting the delivery of HIV care, exacerbated existing healthcare inequities and vulnerabilities in middle-income countries with limited financial resources. This study aims to set the stage for the systematic review, focusing on the impact of COVID-19 on HIV care in middle-income countries with a focus on barriers and facilitators.
