BACKGROUND During the administration of advanced cardiac life support for resuscitation from cardiac arrest, a combination of vasopressin and epinephrine may be more effective than epinephrine or vasopressin alone, but evidence is insufficient to make clinical recommendations. METHODS In a multicenter study, we randomly assigned adults with(More)
OBJECTIVE To highlight the discrepancies in accelerometry cut-off points of moderate-to-vigorous physical activity (MVPA) according to the definitions of Puyau et al. (MVPA(P)) and Trost et al. (MVPA(T)). RESEARCH METHODS AND PROCEDURES Forty-five children from 8 to 11 years old were monitored with the ActiGraph (ActiGraph, LLC, Fort Walton Beach, FL) for(More)
BACKGROUND This study was designed to model the relationship between an ActiGraph-based "in-school" physical activity (PA) and the daily one among children and to quantify how school can contribute to the daily PA recommendations. METHOD Fifty boys and 43 girls (aged 8 to 11 years) wore ActiGraph for 2 schooldays of no structured PA. The daily(More)
AIM To compare Actigraph-defined moderate-to-vigorous physical activity (MVPA) cutpoints among children, combining statistical and biobehavioural analyses. METHODS One hundred and thirteen children aged 10.0 +/- 0.8 years wore accelerometer for three days. The time they spent in MVPA was estimated using 10 thresholds ranged from 3000 to 3900 cpm.

This study is aimed at updating the relationships between physical activity (PA) and the metabolic syndrome (MetS) and/or insulin resistance (IR) in youth. Cross-sectional, prospective cohort and intervention studies, which examined the effect of PA on MetS, its components and IR in children and adolescents (<18 yrs), were searched by applying a combination(More)

This study was designed to examine the hourly variation in and the interplay between physical activity and sedentary behavior (SB) in order to highlight key time periods for physical activity interventions for children. Data for physical activity and SB obtained with ActiGraph in 56 boys and 47 girls aged from 8 to 11 years. These data were divided into(More)
Clinical decision support systems are a combination of software techniques to help the clinicians in their medical decision making process via functionalities ranging from basic signal analysis to therapeutic planning and computerized guidelines. The algorithms providing all these functionalities must be very carefully validated on real patient data and(More)
INTRODUCTION Out-of-hospital cardiac arrest (OHCA) is an important public health issue with an estimated incidence of 50,000 cases per year in France. Community survival rates for OHCA are still low (approximately 5%). An effective, recognized way to study, assess, and improve OHCA care is to create a standard-format database. OBJECTIVE The aim of this(More)
