Filter by:The goal of this clinical trial is to test the effectiveness of #BabyLetsMove - a 24-week mobile Health and peer health coaching intervention paired with the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) - to increase physical activity and reduce sedentary behavior in pregnant, Black teens in the Mississippi Delta. The main questions it aims to answer are: - Does #BabyLetsMove increase objective moderate-to-vigorous physical activity and decrease sedentary behavior from ≤16 to 26- and 36-gestational weeks compared to usual WIC care alone? - Does # BabyLetsMove decrease the rate of gestational weight gain and mean arterial pressure from ≤16 to 26- and 36-gestational weeks compared to usual WIC care alone? - Is #BabyLetsMove a feasible and acceptable intervention according to the RE-AIM framework? - Using the Practical, Robust Implementation and Sustainability Model and the Consolidated Framework for Implementation Research, what are the barriers to organizational uptake and how can strategies be improved for future testing? Participants will be given three empirically supported behavior goals including (1) watching ≤2 hours of TV or other screen time per day, and (2) walking ≥10,000 steps per day - or - (3) engaging in ≥20 minutes of organized exercise per day. Researchers will compare the #BabyLetsMove groups to the WIC care only groups to see if the #BabyLetsMove intervention improves traditional WIC care for bettering health outcomes ( amongst pregnant, Black teens in the Mississippi Delta.
During general anaesthesia, pulmonary atelectasis has been shown to occur in 85 to 90% of patient. Pulmonary atelectasis increases occurrence of postoperative pulmonary complication including pneumoniae. Pulmonary atelectasis can be prevented or reversed by alveolar recruitment manoeuvres (ARM). Two methods for ARMs have been described. A sustained continuous positive airway pressure (CPAP) or a stepwise increase in PEEP.The transient increase in intrathoracic pressure during ARMs decreases venous return and increases pulmonary vascular resistance. This result in a decrease in right and left ventricular stroke volume (SV). Finally, the deleterious hemodynamic effects of ARMs may be exacerbated by hypovolemia, heart failure, and in patients with chronic treatment wich impedes cardiovascular responses to hypovolemia. At our best knowledge, there is no study which compared the hemodynamic effects of ARM using sustained CPAP or stepwise increase in PEEP. Consequently, the present study was designed to examine the hemodynamic effects of 2 ARM methods in anesthetized patients.
The ideal mean arterial pressure in patients with septic shock is unknown. The expert's recommandations have stated a target between 65 and 70 mm Hg. However the scientific basis are weak. Indead there are only few prospective studies which addressed this question without clear answer. Therefore we designed a RCT in order to assess the effect on mortality of two levels of mean arterial pressure in patients with septic shock.(800 patients, 30 centres)
