Reliability and Validity of the ONAPS Physical Activity Questionnaire in Assessing Physical Activity and Sedentary Behavior in French Adults.

This study was conducted to assess the validity and reliability of a new questionnaire, the ONAPS-PAQ, developed to assess physical activity (PA) and sedentary behaviors (SB) in the general population. A total of 137 healthy adults aged 18 to 69 years were included. Following completion of two physical activity questionnaires (ONAPS-PAQ and GPAQ, the Global physical activity questionnaire) to study concurrent validity, participants wore an accelerometer (UKK-RM42) for 7 days to study criterion validity.

Does legislative framework favors prescription of physical activity in primary care ? The French experience.

Objective: Regular physical activity (PA) is a key element in chronic disease management. We studied the effect of a recent legislative framework given to physical activity prescription (PAP) on practices, motivations, barriers, and needs for PAP in primary care among general practitioners (GP) of the Auvergne-Rhône-Alpes region, France.

Methods: Our cross-sectional survey used a self-administrated questionnaire through two recruitment methods: e-mail address (online group) and face-to-face (office group).

BET 1: bedside ultrasound for the diagnosis of necrotising fasciitis.

A short-cut review was carried out to establish whether bedside ultrasound was accurate at diagnosing necrotising fasciitis in patients with limb infections. A total of 187 papers were found using the reported searches, of which one presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this paper is tabulated.

Effect of graded leg cycling on postischaemic forearm blood flow in healthy subjects.

This study assessed in healthy subjects, the effect of leg cycling on the forearm vascular responses to ischaemia to confirm previous results showing that exercise-induced sympathetic activation during leg cycling reduced postischaemic forearm hyperaemia. Seven young healthy subjects performed two bouts of cycling exercises at 50% and 80% of their maximal aerobic capacity (Ex(50), Ex(80) respectively) during which forearm arterial blood flow was successively occluded for 40, 90 and 180 s. Control forearm blood flow (FBF) and postischaemic forearm blood flow (pi-FBF) measured at the release of arterial occlusions were assessed using plethysmography.

Forelimb postischaemic reactive hyperaemia is impaired by hypotensive low body negative pressure in healthy subjects.

Local metabolic conditions adapt blood supply to metabolic requirement by a direct effect on vascular smooth muscles and indirectly by modulating sympathetic vasoconstrictor effectiveness. During exercise, sympathetic nervous activity could in turn interfere on local metabolic control of vascular tone and restrain blood flow to active muscles. In order to investigate that interaction non-invasively, we measured postischaemic reactive hyperaemia (RH) in the forelimb of eight healthy young men (22.
