Active clinical trials for "Weight Loss"

Weight loss is a frequent problem associated with Alzheimers disease (AD). Mirtazapine has weight loss as a frequent side effect. The aim of this retrospective study is to check whether mirtazapine 30 mg (once daily) can counteract weight loss in patients with AD or mixed dementia (AD + vascular).

The sympathetic nervous (SNS) and the renin angiotensin aldosterone system (RAS) have a direct impact on renal hemodynamic, hormonal secretion and vasoactive peptide. Many mechanisms including the SNS, RAS and renal sodium handling could explain the pathogenesis of hypertension in obese patients. Lifestyle changes and bariatric surgery induce weight loss, which is associated with blood pressure lowering in obese patients. A diminution in the renal sympathetic stimulation and RAS activation could explain this effect. The AIM of this study is to show that weight loss induced by bypass surgery in obese patients affects renal salt excretion under " low body negative pressure (LBNP)" conditions . Secondary objectives are to investigate the impact of weight loss on renal hemodynamic (glomerular filtration rate (GFR), renal plasma flow) and neurohormonal responses under " low body negative pressure conditions ". We will also analyse renal blood oxygenation with Blood Oxygenation dependant IRM (BOLD-IRM) technique before and after weight loss. The population of this study will consist in two groups including 36 patients. The first one will include 24 obese patients that are going to undergo a bariatric surgery. The second one will include 12 obese patients without any weight loss associated surgery. Both group will undergo 3 investigation days. Each patient will have to undergo a screening visit that will provide dietary advice to ensure a standardized salt intake (120-180 mmol/day) for the duration of the study. The first investigation will define baseline, the second and third day of investigation will take place after 3 month and 12 month after bariatric surgery for surgical patients or after baseline for patients without surgery. One to two weeks before phase 1 and 3 patients will perform a BOLD-MRI. The surgery group will undergo bariatric surgery between the first investigation phase (baseline) and the second. An ambulatory blood pressure and 24-hour urine collection will precede each investigation day. An investigation day consists in renal hemodynamics, neurohormonal and natriuretic response measurements before, during and after 60 min of LBNP at -30mbar . The duration of the study per subject is going to take 12 months.

This is a prospective mixed methods study to assess weight changes in women randomized to receive Implanon ® or Depo Provera® (DMPA) immediately postpartum compared to women who choose non-hormonal contraception or no contraception immediately postpartum. After enrollment, subjects return for a visit at 3, 6 and 12 months postpartum to be asked a series of questions, take a pregnancy test, and be weighed. Total length of participation for each subject is 1 year or until pregnancy.

The purpose of this study is to determine communication content and strategies in primary care that predict improvement in weight status among overweight school-age children.

RATIONALE: A culturally sensitive weight loss program for obese African American breast cancer survivors may be more effective than a standard weight loss program in helping women lose weight. PURPOSE: This randomized clinical trial is studying personalized weight loss counseling to see how well it works in African American women who are breast cancer survivors.

Standard antiviral treatment consists of weekly injections with Peginterferon-α in combination with ribavirin. This treatment may lead to significant weight loss (7% within 24 weeks on average), with decreased quality of life. In this study the investigators will examine in 50 patients whether nutritional advise and support can prevent weight loss during antiviral therapy.

This study objectives are the following. To describe the updated clinical presentation, indications, and multidisciplinary medical management of patients with a failed and/or complicated jejunoileal bypass (JIB). To analyze the feasibility, safety, and efficacy of one-stage laparoscopic re-operative gastric bypass surgery for failed and/or complicated Jejunoileal bypass (JIB) for weight loss. To determine what factors or strategies are associated with a successful outcome. In particular, the completion of the surgery in one stage with a laparoscopic approach.

Patients with cancer often experience appetite loss and weight loss unintentionally. Rapid weight loss negatively impact on physical functioning, quality of life, and overall survival. Patients will be randomly assigned into two groups. An intervention with acupuncture may slow down or stop the progression of cancer-related anorexia and weight loss.

The first step in any clinical intervention against obesity involves sustained lifestyle changes. Researcher can use these strategies to beneficial the effects of weight and on cardiovascular risk. The researcher develope methods for assessing the effectiveness use optical technology to make such assessments, specifically in the area of fatty tissue can predict the effectiveness of the intervention in causing weight reduction and treating metabolic disease.

To assess the feasibility to translate an automated weight loss message intervention to a weight loss clinic population. Aim 1: To assess feasibility of translating the intervention in a clinic for patients who recently completed a structured weight loss program. Aim 2: To assess the ability to capture a trajectory of self-reported weight over 6 months through an automated intervention.
