Active clinical trials for "Weight Loss"

This is a randomized control trial testing the effect of walnut supplementation on prostate cancer progression in 50 men with biopsy confirmed prostate cancer and planning to undergo RP. Patients consented to the study will be randomly assigned to either continue their usual diets (control arm) or to the walnut arm for 4-10 weeks depending on the window between their consent date and the date for RP.

The current project aims at evaluating the feasibility and efficacy of a multi-disciplinary weight loss program, using an innovative and simple dietary intervention at the American University of Beirut Medical Center (AUB-MC). Such intervention is expected to enhance patients' compliance and adherence to lifestyle changes. In addition, the program includes supervised exercise sessions and behavioral therapy. Therefore, our project proposes an evidence based approach to close the obesity treatment gaps.

The therapeutic problem of obesity is weight control, a major difficulty, involving a significant change in eating behavior. A number of studies show that there are many factors of resistance to weight loss whether they are physiological, genetic, environmental pressure related, or psychological and behavioral. For some patients, the surgical approach seems the best alternative. Indeed, bariatric surgery is an effective therapeutic weapon in patients with morbid obesity. However, it has been shown that approximately 25% of patients are failing at two years of this surgery (Reinhold's index). Some of the failed subjects may benefit from surgical revision. As for the others, no intervention is currently proposed to them. Studies have shown that the psychological profile of patients who are candidates for bariatric surgery is predominantly impulsive, very anxious with a tendency to depression. The stress level of these patients would be important, and they would have low self-esteem. This study hypothesize that, in these patients, the establishment of hypnotherapeutic management associated with the usual dietary monitoring could modify eating habits thus promoting weight loss and an improvement in self-esteem , stress and anxiety compared to dietary monitoring alone.

This optimization trial will examine three tracking (or "self-monitoring") strategies for weight loss -- tracking dietary intake, steps, and/or body weight -- all delivered through digital health tools. The purpose of the study is to evaluate the combination of these strategies that maximizes 6-month weight loss in the context of a standalone digital health intervention for adults with overweight or obesity. The investigators will recruit 176 total participants to the trial. Recruitment will occur through remote channels. Interested individuals will be directed to an online screening questionnaire; those who are eligible will then be invited to attend an initial remote session with study personnel to ensure interest and eligibility in the study. The weight loss intervention will last 6 months, and all participants will receive a "core" treatment consisting of goal setting, behavioral lessons, action plans, and tailored feedback - all of which will be delivered remotely. Depending on which group participants are assigned to in the study, some individuals will be asked to track their dietary intake, their steps, and/or their body weight via digital tools. All study tasks will occur remotely, thus, participants never need to come in-person for any intervention or assessment tasks. The investigators will use the Multiphase Optimization Strategy (MOST) framework to identify the most effective combination of self-monitoring strategies. The factorial design will allow the research team to determine the unique and combined impact of each self-monitoring component on weight change. The primary outcome is weight change from baseline to 6 months. The research team will also assess self-monitoring engagement over 6 months and its association with weight change. To complement the main trial, the research team will also randomize half of participants to receive an interactive orientation video, in order to assess its impact on trial retention at 6 months. Overall, the information gathered from this trial will enable the construction of an optimized digital health intervention for weight loss that can be delivered remotely, which, if found to be effective, could have high potential for scalability.

Concurrent chemoradiotherapy(CCRT) is the principal treatment for nasopharyngeal carcinoma(NPC). Studies have shown that malnutrition is very common in patients with NPC after chemoradiotherapy. Malnutrition can lead to weight loss, treatment interruption, prolonged stay in hospital, increased treatment costs, reduced tolerance to anti-tumor therapy, reduced quality of life and shortened survival time. Nutritional intervention can improve the nutritional status, reduce treatment-related toxicity and improve the survival of patients with NPC. The first choice of nutritional intervention is oral nutritional supplements(ONS). Some retrospective studies with small samples have found that early nutritional intervention can reduce weight loss and severe oral mucositis in patients with NPC, compared with late nutritional intervention. Therefore, the investigators proposed the hypothesis that ONS from the beginning of radiotherapy can reduce the nutritional impairment, treatment-related toxicity and treatment costs of patients with NPC, and improve their quality of life. The aim of this multicenter randomized controlled clinical trial is to evaluate the efficacy and cost utility of ONS from the beginning to the end of radiotherapy.

Psoriatic Arthritis (PsA) is a type of auto-immune condition that affects roughly 90,000 Canadians. Patients with PsA often experience joint pain, skin problems, and issues with mobility that negatively impact their quality of life. Compared to the general population, patients with PsA are at a higher risk of having obesity (excess body weight). Although there is no cure for PsA, medications can be helpful for symptoms, and weight loss can provide an added benefit to the effectiveness of medications. Behavioral weight loss treatment (BWLT) is a proven way to lose weight and keep it off. BWLT usually includes individual or group sessions with a health professional to learn strategies and tools to change behaviours and thoughts in order to support weight loss. However, few studies have designed a BWLT with the unique needs of patients with PsA in mind. Before testing new treatments for chronic disease in large, expensive studies, it is important to do smaller-scale research to make sure that a future large study will be successful. In line with this, the objective of our study is to test the feasibility of a future, large study of a BWLT for patients with PsA and obesity. In other words, our small feasibility study will investigate how convenient, reasonable, and acceptable the future study's procedures are, using a small group of people with PsA and obesity. People who have PsA and obesity will take either a special BWLT program, or receive usual care for PsA from a community-based rheumatologist. Those in the BWLT group will complete 16 online group sessions to help them learn cognitive and behavioral changes to help improve their health and manage weight. After 24 weeks, we will determine study completion rates, examine patient satisfaction, and assess whether the BWLT was provided to people as-designed. We believe this research will help with efforts to provide more effective treatments to patients with PsA to help them lose weight and improve their quality of life through reduced pain and symptoms.

Approximately 20-40% of patients with ulcerative colitis (UC) are obese. The investigators have demonstrated that obesity adversely impacts disease course in patients with UC, leading to higher risk of persistently active disease, surgery, hospitalization, and treatment failure, particularly in biologic-treated patients. Intentional weight loss is effective in improving disease outcomes in patients with inflammatory arthritis, but there is limited data on its impact in UC. While dietary interventions for weight loss have limited efficacy and endoscopic bariatric interventions may be too invasive in patients with UC with active gastrointestinal symptoms, pharmacological weight loss with a highly effective oral agent may be a novel strategy to induce weight loss and augment the efficacy of biologic therapy in UC. Hence, the investigators are conducting a pilot, phase 2A, 22-week, randomized, placebo-controlled clinical trial of phentermine-topiramate in obese patients with active UC starting on a new biologic agent (infliximab, adalimumab, golimumab, vedolizumab). The overall objective is to (1) evaluate the efficacy, safety and tolerability of phentermine-topiramate, and (2) to assess the impact of pharmacological weight loss on clinical outcomes, inflammatory burden and biologic trough concentration in patients with UC. The central hypothesis is that phentermine-topiramate will be safe, effective, and well tolerated in patients with UC, and weight loss would achieve higher rates of clinical and biochemical remission, and higher biologic trough concentration.

The aim of this randomized, parallel, two-arm, placebo-controlled, double-blind, multicenter clinical trial is to evaluate the efficacy of a dietary supplement on weight loss and psychological well-being in overweight individuals.

Regional anaesthetic techniques, or nerve blocks, are commonly used to provide postoperative pain relief for patients undergoing surgery. At present in University Hospital Galway, it is standard practice for patients undergoing bariatric sleeve gastrectomy surgery to receive a regional anaesthetic technique to improve their postoperative pain. There are a number of different regional anaesthetic options available for this surgery, but as yet, published evidence regarding which specific approach confers most benefit for patients is lacking. This study aims to compare two regional anaesthetic techniques - erector spinae plane blockade versus serratus anterior plane blockade plus subcostal transversus abdominus plane blockade - and assess if one approach provides a superior quality of recovery postoperatively for sleeve gastrectomy patients over the other.

In the Time-Restricted Eating: Microbiome and Bone (TREMBO) study, the primary goal is to determine the effect of time-restricted eating with caloric restriction compared to caloric restriction alone on body weight, the gut microbiota, and bone health in older women who are overweight or obese.
