Filter by:The aim of this study is to gain insight into brain structure and the neural networks that control taste and eating behaviour in patients with severe obesity undergoing a primary sleeve gastrectomy (SG) or a lifestyle intervention for weight loss compared with normal weight individuals, using functional magnetic resonance imaging (fMRI).
The Communities for Healthy Living (CHL) program is a family-focused intervention to promote healthy lifestyle behaviors including diet and physical activity among children (age 3-to 5-years) and their families, enrolled in Head Start.
The objective of the present study is to estimate the effect of nudging proposals on the students' Body Mass Index, based on changes made in the school environment. This is a factorial randomized community trial, which will be conducted in 18 public schools in the city of Duque de Caxias, RJ.
The objective of the present study is to implement and evaluate the effect of a counseling program to promote healthy eating and practice of physical activity in the nutritional status, quality of life and prognosis of women Type I (endometrioid) endometrial cancer.
Clinical trial, multicenter, double-blind, placebo-controlled, comparative of three parallel groups, randomized treatment to assess the efficacy and safety using a fixed dose combination of metformin hydrochloride with fluoxetine as adjunctive treatment in patient with obesity or overweight in order to generate new knowledge and give a greater number of therapeutic options to the clinicians, one group will receive metformin 1700 mg and 40 mg of fluoxetine; Another group will receive metformin 1000 mg with 40 mg of fluoxetine, and a third group called control will receive placebo. The above described treatments will be administered according to the "Dosage Schedule" The three groups will receive tablets of physical characteristics equal to the reference drug to preserve the blinding.
Hepatocellular carcinoma (HCC) is the most common primary malignant liver tumor and has a grave prognosis. Obesity is an epidemic in the US.Patients with HCC and obesity are not candidates for liver transplantation, depriving them of the best option for cure from HCC. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss.The purpose of this study is to determine if Left gastric artery embolization (LGAE) in patients with cirrhosis and HCC who are not transplant candidates due to morbid obesity, leads to clinically significant weight loss with eligibility for liver transplantation.
Increasing rates of obesity over the last few decades have led to growing demand for bariatric surgery, which may resulted in decreased comorbidities and improved patient outcomes. Laparoscopic bariatric surgery has several clinical benefits in terms of improved quality of analgesia, reduced pulmonary complications, enhanced recovery of bowel function, less immune suppression, and shortened duration of hospital stay than open laparotomies. Some investigators reported delayed return of bowel function for approximately two days after laparoscopic bariatric surgery, despite it occurred one day earlier than after open laparotomy. This potentially can lengthen the duration of hospital stay after bariatric procedures. With the impeding cost of health care in the developing countries, safely reducing length of stay is essential. Other investigators reported early return of bowel movements during the first postoperative day in 65% of patients undergoing laparoscopic gastric bypass surgery due to reduced morphine use with implementation of a multimodal analgesia strategy including ketorolac, and propoxyphene hydrochloride/acetaminophen. Lidocaine was investigated in several studies for its use in multi-modal management strategies to reduce postoperative pain and opioid use and enhance recovery. A recent Cochrane review including 45 trials demonstrated that systemic administration of lidocaine was associated with reduced pain scores at most of 'early time points' in patients undergoing laparoscopic abdominal surgery (MD -1.14, 95% CI -1.51 to -0.78; low-quality evidence), shorter times to first flatus (MD -5.49 hours, 95% CI -7.97 to -3.00; low-quality evidence) and first bowel movement (MD -6.12 hours, 95% CI -7.36 to -4.89; low-quality evidence), and less risk of paralytic ileus (risk ratio (RR) 0.38, 95% CI 0.15 to 0.99; low-quality evidence). However, no evidence of effect was found for lidocaine on shortening the time to first defecation. This low-quality evidence may be related to the heterogeneity between the studies in respect to the optimal dose, timing and duration of the administration of intravenous lidocaine.
Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder in reproductive age women. PCOS is usually characterized by an excessive androgen production, menstrual irregularities, and polycystic ovaries. Women with PCOS are often obese and have a varying degree of insulin resistance (IR). Weight reduction constitutes the initial treatment for these patients. Metformin has proven to be useful in IR and is frequently used in PCOS. However metformin use may be accompanied by gastrointestinal discomfort, and a high abandon rate. Other therapeutic alternatives such as magnesium and polyunsaturated fatty acids have been used in other IR states and may be useful in PCOS. The aim of this study is to asses the efficacy of these alternatives in obese PCOS patients.
The purpose of this study is to examine how physical activity and lifestyle factors influence postoperative recovery and postoperative complications after bariatric surgery. The hypothesis is that physically active people, with a healthy alcohol consumption and non smokers have shorter lengths of hospital stay, shorter sick-leave, fewer re-hospitalizations and fewer re-operations, fewer complications as well as a faster recovery after a surgical procedure. The investigators also hypothesize that possible risk factors for non-surgical postoperative complications e g abdominal discomfort are also life-style related factors such as smoking, high alcohol consumption, low level of physical activity, as well as other risk factors such as prior frequent abdominal pains (e g irritable bowel syndrome symptoms), high levels of anxiety and/or depression, difficulties with coping with the changed food intake regimen after obesity surgery, and generally high sensitivity for painful-sensations and nausea. First aim of this study is to investigate how life style factors prior to obesity surgery are related to hospital stay, sick-leave, immediate postoperative complication rates and the rate of resumption of QoL and normal physical function. The second aim of the study is to identify risk factors for the development of chronic abdominal discomfort and dumping symptoms after obesity surgery.
A number of studies have shown that short duration, high intensity interval training can improve health-related outcomes, such as insulin sensitivity and cardiorespiratory fitness. However, these often use specialized equipment, such as cycle ergometers, which makes it difficult to roll these interventions out for wide-scale use in the general population. This study aims evaluate the effects of a high intensity shuttle running intervention on insulin sensitivity, fitness and related cardiometabolic risk factors in men who are currently inactive. Participants will be randomized into intervention (4 weeks of shuttle running) and control groups. We hypothesize that the shuttle running programme will result in improved insulin sensitivity, fitness and increased fat oxidation at rest compared with the control group.
