Filter by:The aim of this randomized, crossover clinical trial is to determine the efficacy of a gut microbiota-targeted nutritional intervention containing a blend of fermentable fibers and polyphenols (FP) for mitigating increases in GI permeability, and decrements in immune function and neuropsychologic performance following rapid ascent to simulated high altitude. Fifteen healthy young adults will participate in each of three study phases that include a 14-day supplementation period in which participants will consume 1 of 2 supplement bars: placebo (PL, will be consumed during 2 phases) and FP supplementation (will be consumed during one phase only). During the final 2-d of each phase, participants will live in a hypobaric chamber under sea level or high altitude conditions.
Long-term DAPT is recommended after percutaneous coronary intervention (PCI) in patients with coronary artery disease. However, antiplatelet therapy may have adverse consequences, the most common of which is gastrointestinal mucosal injury with ulceration and bleeding. The extent to which an an abbreviated DAPT strategy reduces gastrointestinal mucosal injury has not been studied, principally due to the lack of sensitive, noninvasive measurements capable of detecting gastrointestinal injury.ANKON® magnetically controlled capsule endoscopy (AMCE) is a non-invasive, active controlled system which affords assessment of the stomach and entire small intestine.The current randomized study will assess gastrointestinal mucosal injury and bleeding via AMCE in patients on three different antiplatelet regimens and establish a gastrointestinal mucosal injury scoring system which may prove useful in guiding optimal antiplatelet agent usage after PCI.
Emergent abdominal surgeries have very high rate of wound contamination due to exposure to bacteria from GI tract. There are several different approaches to wound management in these patients including wet-to-dry dressing or application vacuum assisted device on the wound. The investigators propose using the vacuum assisted device with Dakin's solution on patients undergoing emergency surgery for hollow viscus perforation installed immediately at the end of operation and remained there for the first 3 postoperative days, followed by delayed primary closure on postoperative day 4. The investigators believe this technique can achieve earlier wound closure, decrease patient discomfort, improve cost savings, and potentially standardize and revolutionize the investigators management of heavily contaminated wounds.
