BACKGROUND The study aim was to test the accuracy (intra and interobserver variability), sensitivity, and specificity of a simplified noninvasive ultrasound methodology for mapping superficial and deep veins of the lower limbs. METHODS 62 consecutive patients, aged 62 ± 11 years, were enrolled. All underwent US-examinations, performed by two different investigators, of both legs, four anatomi...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

HYPOTHESIS Risk factors for the presence and extent of Barrett esophagus (BE) can be identified in patients with gastroesophageal reflux disease (GERD). DESIGN Case-comparison study. SETTING University tertiary referral center. PATIENTS Five hundred two consecutive patients with GERD documented by 24-hour esophageal pH monitoring and with complete demographic, endoscopic, and physiologica...

OBJECTIVE To describe the long term costs, health benefits, and cost effectiveness of laparoscopic surgery compared with those of continued medical management for patients with gastro-oesophageal reflux disease (GORD). DESIGN We estimated resource use and costs for the first year on the basis of data from the REFLUX trial. A Markov model was used to extrapolate cost and health benefit over a ...

BACKGROUND & AIMS Central adiposity has been implicated as a risk factor for Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC), possibly promoting the progression from inflammation to metaplasia and neoplasia. We performed a systematic review and meta-analysis of studies to evaluate the association between central adiposity and erosive esophagitis (EE), BE, and EAC, specifically expl...

OBJECTIVE To measure the relative risks of adenocarcinomas of the oesophagus and gastro-oesophageal junction associated with measures of obesity, and their interactions with age, sex, gastro-oesophageal reflux symptoms and smoking. DESIGN AND SETTING Population-based case-control study in Australia. PATIENTS Patients with adenocarcinomas of the oesophagus (n = 367) or gastro-oesophageal jun...

Abstract Long-term maintenance missions present a challenge for low-orbit heterogeneous area-to-mass ratio (AMR) microsatellite constellations due to inconsistent fuel consumption and carrying capacity. Based on the idea of cooperative control, fuel-rich satellites is properly increased in this paper assist fuel-starved saving fuel, so as optimize balance each satellite extend controllable life...

BACKGROUND Perioperative lidocaine treatment is commonly used in horses that undergo surgical treatment of colic, to prevent or treat postoperative ileus and reduce the effects of intestinal ischaemia-reperfusion injury. However, its clinical efficacy has not been evaluated in a large population of horses undergoing small intestinal surgery. The aim of the current study was to evaluate whether ...
