Evaluating the Transformative Impact of Online Education on Medical Student Learning Outcomes.

Introduction: The COVID-19 pandemic forced educational institutions worldwide to shift to online learning as a means to continue education during lockdowns and social distancing measures. This study investigates the effectiveness of online learning in comparison to traditional on-campus learning, specifically within the context of medical education.

Methods: Two hundred and three first- and second-year medical students at King Saud University participated in this randomized experimental study.

High prevalence of lack of knowledge and unhealthy lifestyle practices regarding premature coronary artery disease and its risk factors among the Saudi population.

Objective: Literature regarding coronary artery disease (CAD) and awareness of its risk factors is available in Saudi Arabia (SA). However, it is lacking with respect to premature coronary artery disease (PCAD). Therefore, it is necessary to evaluate the lack of knowledge of this underrepresented critical issue and to devise a well-constructed strategy for PCAD.

Expression and function of mechanosensitive ion channels in human valve interstitial cells.

Background: The ability of heart valve cells to respond to their mechanical environment represents a key mechanism by which the integrity and function of valve cusps is maintained. A number of different mechanotransduction pathways have been implicated in the response of valve cells to mechanical stimulation. In this study, we explore the expression pattern of several mechanosensitive ion channels (MSC) and their potential to mediate mechanosensitive responses of human valve interstitial cells (VIC).
