BACKGROUND Difficult-to-control asthma has been associated with gastroesophageal acid reflux. Acid-suppressive treatment has been inconsistent in improving asthma control. OBJECTIVE To determine whether a proton-pump inhibitor improves asthma control in adult asthmatic patients with acid reflux symptoms. DESIGN Multicenter, double-blind, randomized,(More)
BACKGROUND An observational study in veterans showed that a novel water method (water infusion in lieu of air insufflation) enhanced cecal intubation and willingness to undergo a repeat scheduled unsedated colonoscopy. OBJECTIVE To confirm these beneficial effects and significant attenuation of discomfort in a randomized, controlled trial (RCT). DESIGN(More)
OBJECTIVES Minimal sedation obviates patient recovery burdens, but intolerable pain limits success of cecal intubation. Painless or minimally uncomfortable insertion ensures success of cecal intubation, current patient satisfaction, and willingness to repeat future colonoscopy with minimal sedation. Water immersion (WI) and water exchange (WE), when(More)
BACKGROUND Water-aided methods for colonoscopy are distinguished by the timing of removal of infused water, predominantly during withdrawal (water immersion) or during insertion (water exchange). OBJECTIVE To discuss the impact of these approaches on colonoscopy pain and adenoma detection rate (ADR). DESIGN Systematic review. SETTING Randomized,(More)
BACKGROUND Despite advances in bowel preparation methods, the quality of bowel preparation in some patients undergoing colonoscopy remains unsatisfactory. The effect of telephone re-education (TRE) on the day before colonoscopy on the quality of bowel preparation and other outcome measures had not been studied. METHODS A prospective colonoscopist-blinded(More)
BACKGROUND: Colonoscopy has been reported to fail to prevent some post screening colonoscopy incident cancers or minimize cancer mortality in the proximal colon. These reports question the effectiveness of colonoscopy in detecting all proximal adenomas. Diminutive ones which can be obscured by residual feces are particularly at risk. The water method(More)
An abundant seed protein, which is exceptionally rich in the sulfur-containing amino acids, methionine (18%) and cysteine (8%), is synthesized in Brazil nut embryos about 9 months after flowering. This sulfur-rich protein consists of two low-molecular-mass polypeptide components, a 9-kDa polypeptide and a 3-kDa polypeptide. The two-subunit polypeptides(More)
Endoscopic reflectance spectrophotometry was used to compare the effect of vasopressin and propranolol on gastric mucosal hemodynamics in dogs with surgically induced esophageal varices and prehepatic portal hypertension. Reflectance spectrophotometry provides indices of mucosal hemoglobin concentration (IHB) and oxygen saturation (ISO2). Hyperemia(More)
Hip fracture is a common injury among the elderly. Although patients who receive hip fracture surgery carry the best functional recovery compared to other treatment modalities, the presence of postoperative pulmonary complications, such as atelectasis, pneumonia, and pulmonary thromboembolism, may contribute to increased length of hospital stay,(More)
Conditioned medium from mesenchymal stem cells (MSC-CM) may represent a promising alternative to MSCs transplantation, however, the low concentrations of growth factors in non-activated MSC-CM hamper its clinical application. Recent data indicated that the paracrine potential of MSCs could be enhanced by inflammatory factors. Herein, we pre-activated(More)
