OBJECTIVE To find ways to improve response rates of medical and health surveys. We investigated whether a prenotification letter instead of a second reminder and varying senders of the questionnaires would affect response rates. STUDY DESIGN AND SETTING We present the results of two studies. In the first study, four groups were compared that either received a prenotification letter (group 1 a...
متن کاملVentilation during cardiopulmonary bypass did not attenuate inflammatory response or affect postoperative outcomes
INTRODUCTION Cardiopulmonary bypass causes a series of inflammatory events that have adverse effects on the outcome. The release of cytokines, including interleukins, plays a key role in the pathophysiology of the process. Simultaneously, cessation of ventilation and pulmonary blood flow contribute to ischaemia-reperfusion injury in the lungs when reperfusion is maintained. Collapse of the lung...
متن کاملTiming of carbohydrate ingestion did not affect inflammatory response and exercise performance during prolonged intermittent running

However, the influence of timing of carbohydrate ingestion remains unclear. PURPOSE The present study investigated the influence of different timing of carbohydrate ingestion during a simulated soccer game on exercise performance, metabolic and inflammatory response...
