The purpose of this study is to assess the safety profile of bariatric embolizations and confirm published reports of sustained post-procedural weight loss, and pathologically assess post-procedural metabolic effects.
Prospective multicenter observational clinical study on a dietary regimen in obese patients scheduled for bariatric surgery.
Obesity is an epidemic in the US. With progression of obesity, Nonalcoholic steatohepatitis (NASH) has been a growing public health issue. Presently there is no cure for NASH.Prevention of progression of fibrosis in NASH is crucial, as they are at a high risk for cirrhosis and may need liver transplant. 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 obesity and NASH leads to clinically significant weight loss with improvement of NASH.
Title: Embolization of Gastric Arterial Supply for Weight Loss Sample size: 10 patients Study Population: Morbidly obese patients who were seen by the bariatric surgery program at Toronto Western Hospital but are either not interested or not eligible for surgery. Study Design: Single center, randomized, prospective, non-blinded pilot study. Study Duration: 12 months (November 2015 - December 2015). Agent: 150-250 micron polyvinyl alcohol particles Primary objective: To further evaluate the safety of embolization of the left gastric and gastroepiploic arteries. To determine if either or both will result in significant weight loss and decrease in waist circumference among obese patients. Primary objective measure: The number of adverse events in a 1 year period will be recorded. The weight change from baseline will be recorded.
Evaluation of the subchondral mineralization plate after excess weight loss in patientes undergoing bariatric operation by means of CT-osteoabsorptiometry.
Elevated subconscious nervous system activity is a characteristic of the obese state and contributes importantly to the risk of heart disease and diabetes. This project will compare sympathetic nervous system activity and function in a group of obese persons with differing levels of sugar tolerance (normal, impaired and type 2 diabetic). Inter-relationships with insulin action, blood pressure, heart and kidney function will be determined before and after a 4-month weight loss and 3-month weight loss maintenance program. It is hypothesized that the transition from normal sugar tolerance to impaired sugar tolerance to type 2 diabetes will be accompanied by escalating sympathetic nervous system dysfunction. Furthermore, that weight loss will favorably improve sympathetic function, with greatest benefits occurring in those subjects who are insulin resistant with high blood insulin concentration.
The relative risk of psoriasis and its severity are directly related to the body mass index (BMI).Patients with psoriasis likely undergo a vicious circle where obesity and skin disease reinforce each other. To investigate patients' opinion about their body weight (BW), the possibility of dietary approach to psoriasis, and to examine the adherence and the effects of hypo-energetic diet to maintain disease remission in obese patients a dedicated questionnaire was administered to 200 consecutive patients (125 men and 75 women) with moderate-to-severe chronic plaque psoriasis investigating whether diet factors could influence psoriasis severity and course. In second part of study, obese patients with psoriasis in remission (PASI improvement ≥ 75%) for at least 12 weeks after methotrexate therapy were randomly assigned to receive a hypo-caloric diet or free diet for 24 weeks, and then followed up for additional 12 weeks.
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.
Mucositis and xerostomia are the most common complications of head and neck (H&N) irradiation, and the combination of chemotherapy and radiation therapy is associated with a significantly higher rate of complications. Mucositis usually develops during the second or third week of a course of standard radiotherapy, and the pain it causes peaks between the third and last week of treatment. The pain then persists for at least one month following the completion of therapy, and may be so overwhelming that it prevents patients from swallowing food and fluids. The patient is therefore at a risk to develop malnutrition, and must be treated vigorously. In this respect, the use of gastrostomy tubes (PEG) has been shown to be beneficial. Completion of the full course of irradiation, without interruption, is important for achieving best possible results in cancer of the H&N. It is therefore essential to identify and refer patients at risk to receive effective and timely nutritional intervention. Since mucositis represents a clinical continuum which differs between patients, it is difficult to assess before-hand which patients will be at risk. There is no simple laboratory tool available, which could predict which patients are susceptible to develop severe mucositis and dysphagia, and eventually will require a feeding gastrostomy. The first phase of mucositis, inflammation, results in the production of pro-inflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α). In general, the inflammatory cytokines IL-1, interleukin-6 (IL-6) and TNF-α are elevated in inflammatory conditions and are found in increased levels in blood and tissue fluid during inflammation, while anti-inflammatory cytokines are produced in a decreased manner. The main purpose of this study is to find the best indicators and prognosticators of mucositis occurring in the healthy oral tissues of H&N cancer patients receiving treatment, and to understand the cytokines balance mechanism of action. Assuming there is a correlation between high cytokines levels during inflammation and the severity of radiation induced mucositis, finding these prognostic factors may help us predict during the first part of the treatment the need for PEG, placing it prior to the complications associated with severe mucositis on one hand, and avoiding unnecessary procedures on the other hand.
