Safe driving practices and factors associated with motor-vehicle collisions among people with insulin-treated diabetes mellitus: Results from the Diabetes and Driving (DAD) study.

Introduction: The aim of this study was to assess the prevalence of people with insulin-treated diabetes mellitus (ITDM) who have discussed issues related to diabetes and driving with their health care providers (HCPs). We also sought to determine the safe driving practices that are currently employed by this group. Finally, we investigated the factors that might increase the risk of motor-vehicle collisions (MVCs) among this group in Saudi Arabia.

Heart Rate Beat-to-Beat Slope Change during Six-Minute Walk Test: a Useful Clinical Tool for Estimating Fitness level.

Background: The six-minute walk test (6MWT) is one of the most common exercise tests and is used to estimate the level of physical fitness. This study aimed to evaluate the feasibility of the beat-to-beat heart rate 6MWT slope (6MWTS) and recovery slope for predicting and estimating the level of physical fitness during 6MWT, instead of depending on the distance covered during the test.

Methods: Seventy healthy adult male subjects aged 18 to 27 years were recruited randomly from the general Saudi population in Riyadh.
