Abstract
OBJECTIVES To evaluate the effect of esophageal stimulation on nutritional adequacy in critically ill patients at risk for enteral feeding intolerance. DESIGN A multicenter randomized sham-controlled clinical trial. SETTING Twelve ICUs in Canada. PATIENTS We included mechanically ventilated ICU patients who were given moderate-to-high doses of opioids and expected to remain alive and ventilated for an additional 48 hours and who were receiving enteral nutrition or expected to start imminently. INTERVENTIONS Patients were randomly assigned 1:1 to esophageal stimulation via an esophageal stimulating catheter (E-Motion Tube; E-Motion Medical, Tel Aviv, Israel) or sham treatment. All patients were fed via these catheters using a standardized feeding protocol. MEASUREMENTS AND MAIN RESULTS The co-primary outcomes were proportion of caloric and protein prescription received enterally over the initial 7 days following randomization. Among 159 patients randomized, the modified intention-to-treat analysis included 155 patients: 73 patients in the active treatment group and 82 in the sham treatment group. Over the 7-day study period, the percent of prescribed caloric intake (± SE) received by the enteral route was 64% ± 2 in the active group and 65% ± 2 in sham patients for calories (difference, -1; 95% CI, -8 to 6; p = 0.74). For protein, it was 57% ± 3 in the active group and 60% ± 3 in the sham group (difference, -3; 95% CI, -10 to 3; p = 0.30). Compared to the sham group, there were more serious adverse events reported in the active treatment group (13 vs 6; p = 0.053). Clinically important arrhythmias were detected by Holter monitoring in 36 out of 70 (51%) in the active group versus 22 out of 76 (29%) in the sham group (p = 0.006). CONCLUSIONS Esophageal stimulation via a special feeding catheter did not improve nutritional adequacy and was associated with increase risk of harm in critically ill patients.

Abstract
Background Exercise training as part of a comprehensive cardiac rehabilitation is recommended for patients with cardiac heart failure. It is a valuable method for the improvement of exercise tolerance. Some studies reported a similar improvement with quadricipital electrical myostimulation, but the effect of combined exercise training and electrical myostimulation in cardiac heart failure has not been yet evaluated in a large prospective multicentre study. Purpose The aim of this study was to determine whether the addition of low frequency electrical myostimulation to exercise training may improve exercise capacity and/or muscular strength in cardiac heart failure patients. Methods Ninety-one patients were included (mean age: 58 ± 9 years; New York Heart Association II/III: 52/48%, left ventricular ejection fraction: 30 ± 7%) in a prospective French study. The patients were randomised into two groups: 41 patients in exercise training and 50 in exercise training + electrical myostimulation. All patients underwent 20 exercise training sessions. In addition, in the exercise training + electrical myostimulation group, patients underwent 20 low frequency (10 Hz) quadricipital electrical myostimulation sessions. Each patient underwent a cardiopulmonary exercise test, a six-minute walk test, a muscular function evaluation and a quality of life questionnaire, before and at the end of the study. Results A significant improvement of exercise capacity (Δ peak oxygen uptake+15% in exercise training group and +14% in exercise training + electrical myostimulation group) and of quality of life was observed in both groups without statistically significant differences between the two groups. Mean creatine kinase level increased in the exercise training group whereas it remained stable in the combined group. Conclusions This prospective multicentre study shows that electrical myostimulation on top of exercise training does not demonstrate any significant additional improvement in exercise capacity in cardiac heart failure patients.

Abstract
AIM: Postoperative ileus is the most commonly observed morbidity following ileostomy closure. Studies have demonstrated that the defunctionalized bowel of a loop ileostomy undergoes a series of functional and structural changes, such as atrophy of the intestinal villi and muscular layers, which may contribute to ileus. A single-centre study in Spain demonstrated that preoperative bowel stimulation via the distal limb of the loop ileostomy decreased postoperative ileus, length of stay and time to gastrointestinal function. METHOD A multicentre randomized controlled trial involving patients from Canadian institutions was designed to evaluate the effect of preoperative bowel stimulation before ileostomy closure on postoperative ileus. Stimulation will include canalizing the distal limb of the ileostomy loop with an 18Fr Foley catheter and infusing it with a solution of 500 ml of normal saline mixed with 30 g of a thickening agent (Nestle© Thicken-Up© ). This will be performed 10 times over the 3 weeks before ileostomy closure in an outpatient clinic setting by a trained Enterostomal Therapy nurse. Surgeons and the treating surgical team will be blinded to their patient's group allocation. Data regarding patient demographics, and operative and postoperative variables, will be collected prospectively. Primary outcome will be postoperative ileus, defined as an intolerance to oral food in the absence of clinical or radiological signs of obstruction, that either requires nasogastric tube insertion or is associated with two of the following on or after post-operative day 3: nausea/vomiting; abdominal distension; and the absence of flatus. Secondary outcomes will include length of stay, time to tolerating a regular diet, time to first passage of flatus or stool and overall morbidity. A cost analysis will be performed to compare the costs of conventional care with conventional care plus preoperative stimulation. DISCUSSION This manuscript discusses the potential benefits of preoperative bowel stimulation in improving postoperative outcomes and outlines our protocol for the first multicenter study to evaluate preoperative bowel stimulation before ileostomy closure. The results of this study could have considerable implications for the care of patients undergoing ileostomy closure.

Abstract
OBJECTIVE The closed-loop gastric electrical stimulation (CLGES) abiliti® system provides tailored gastric electrical stimulation activated by food entry into the stomach and sensor-based data to medical professionals. The aim of this study was to analyze behavior changes using sensor-based food intake and activity data in participants treated with the CLGES system. METHODS Food intake and activity data (3D accelerometer) were downloaded at baseline and monthly/bimonthly for 12 months in a subset of patients with obesity (N = 45) participating in a multicenter trial with CLGES. Measured food intake parameters included the number of intakes during allowed and disallowed periods, nighttime intakes, and between-meal snacks (average/d). Activity parameters included time in different levels of physical activity (min/d), sleep/sedentary (h/d), and estimated energy expenditure (EE). RESULTS Weight loss at 12 months averaged 15.7 ± 7.7% of the baseline body weight. Stable reduction in the number of disallowed meals and between-meal snacks (P < 0.05), an increase in all levels of physical activity (P < 0.001), and an increase in activity-based EE (303 ± 53 kcal/d on average, P < 0.001) were seen. CONCLUSIONS Significant improvement in eating and activity was seen in participants. It is hypothesized that feedback of the sensor-based data induced behavioral changes and contributed to weight loss in patients treated with CLGES.

Abstract
BACKGROUND The aim of the study was to evaluate the safety and effectiveness of a novel closed-loop gastric electric stimulation device (abiliti system) featuring a transgastric sensor to detect food intake and an accelerometer to record physical activity to induce and maintain lifestyle changes to treat obesity. METHODS In a prospective, multi-center study, 34 obese subjects (BMI of 42.1 ± 5.3 kg/m(2)) who passed an eligibility evaluation were implanted with the abiliti system. Safety evaluation included an endoscopic exam to assess the intragastric electrode healing. Efficacy evaluation at 1 year of therapy included weight loss, improvements in eating, and exercise behavior and quality of life. RESULTS The transgastric implant controlled by endoscopy was stable for all participants. At 12 months (12 M) the mean excess weight loss (EWL) was 28.7% (95%CI, 34.5 to 22.5%), and mean reduction in BMI was 4.8 ± 3.2 kg/m(2). At 27 months (27 M), the EWL was 27.5% (95% CI, 21.3% to 33.7%). Eating behavior, evaluated by the "Three Factor Eating Questionnaire", showed a significant increase in the cognition factor and decrease in the disinhibition and hunger factors at 12 M in comparison to baseline (p < 0.001). Participants significantly increased their weekly physical activity (p < 0.001). Quality of life was improved in 55.2% of the patients. CONCLUSIONS Gastric electrical stimulation with abiliti system in obese participants is well tolerated and leads to significant 12 M weight loss, which was stable to 27 M. We suggest that weight loss is achieved due to the assessed alteration of eating behavior in particular the reduction in disinhibition and hunger, and the measured increase in physical activity.
