Filter by:The assessment of health status and physical function is fundamental in patients with obesity, as they play an important role among the various factors influencing quality of life in this population. Several studies have shown an association between high BMI values and a significant deterioration in quality of life, especially in women. Excess body fat in obese patients appears to be responsible for impaired muscle function. This causal link is probably linked to dysfunctions in adipose tissue, leading to a decrease in the expression of proteins responsible for muscle contraction. The recent literature highlights an alteration in quality of life, particularly in obese and elderly subjects, for which changes in muscle function are partly responsible. Changes in muscle function can be assessed by simple, rapid and non-invasive tools. These changes in the obese patient could be predictive of reduced quality of life. To our knowledge, no study has evaluated the predictive capacity of muscle alteration assessed by ultrasound on the medium-term quality of life of obese patients. The main objective of this study is to evaluate the predictive capacity of structural alteration of the quadriceps on the decrease in quality of life at 1 year in patients with obesity. The secondary objectives are to assess the association between : - Grip strength and quality of life at 1 year; - Quadriceps muscle strength and quality of life at 1 year; - Ultrasound measurements of the quadriceps and quality of life at 1 year; - Ultrasound measurements of the quadriceps and autonomy at 1 year; - Grip strength and autonomy at 1 year. This is a prospective, monocenter, observationnal and cohort study. All outpatients for nutrition assessment will be included.
This study will investigate the role of dupilumab in the treatment of asthma with comorbid obesity. It is hypothesized that in airway epithelial cells, unique transcriptomic and proteomic expression patterns distinguish allergic and non-allergic patients with asthma and obesity and drive significant differential responses to dupilumab. It is further hypothesized that dupilumab will increase interleukin-13 receptor alpha 2 (IL-13Rα2) levels and/or signaling activity on airway epithelial cells isolated from allergic asthma patients with obesity. This is a pre-clinical research study of dupilumab-induced gene and protein expression analyses in nasal airway epithelial cells of adults with asthma and comorbid obesity. The study primarily seeks to: 1) assess the effect of dupilumab on transcriptomes, phosphoproteomes and secretomes of well-differentiated, primary airway epithelial cells as a function IL-13R subunit expression and IL-13Ra2 signaling, in allergic and non-allergic asthma patients with obesity; and 2) test whether dupilumab-induced gene and protein changes significantly correlate with parameters of airway inflammation in allergic and non-allergic asthma.
This study is open label, with one arm only. In this study will be enrolled patients with obesity (BMI more than 30). Aim of the study is to determine the influence (if any) of a very low calorie ketogenic diet (VLCKD) on gut permeability and liver steatosis. The first objective is to examine the influence of obesity on the prevalence and severity of impaired intestinal permeability and hepatic steatosis. Intestinal permeability means the ability of the intestinal barrier to block the passage of substances potentially harmful to our body. The second objective is to evaluate whether a low-calorie and ketogenic dietary intervention, lasting 6 weeks, can change intestinal permeability and hepatic steatosis
With the development of China's economy, people's living standard have improved, and the dietary structure have changed. Metabolic diseases, such as hypertension, diabetes, hyperuricemia and obesity have gradually become an important health burden in China. The pathophysiological mechanism of renal injury caused by metabolic diseases has always been a hotspot of research. Currently, it is believed that various mechanisms including the activation of Renin-Angiotensin-Aldosterone System, vascular endothelial dysfunction, oxidative stress and inflammatory process may be involved. Although there are differences in renal pathological manifestations caused by different metabolic diseases, the kidney will eventually present ischemic changes and fibrosis with the progression of the disease. So there must be some common pathogenesis. This study is designed to build a disease cohort of patients with chronic kidney disease caused by metabolic diseases, to identify risk factors leading to disease progression and to explore biomarkers for early diagnosis and treatment of kidney damage.
In this preliminary short-term study it is investigated, whether a short olfactory stimulation with distinct odours impacts energy expenditure in patients with obesity and lean patients.
This study will provide nutrition counseling via FaceTime on an iPad to persons with traumatic spinal cord injury (SCI) who are overweight or obese and are at least one-year post-injury. Nutrition counseling may help participants to develop eating behaviors that match the participants' needs and help improve heart health. The purpose of this project is to decrease the risk of complications like obesity, high cholesterol, or diabetes, and explore associations between bowel and bladder function and nutrition. This study will require 3 in person visits that are about 3 months apart. The total length of the study is about 6 months and includes 3 months of telenutrition counseling.
This study will investigate the effects of at least 12 weeks of weekly cold water immersions (water temperature 18ºC) on BAT perfusion in individuals with obesity. BAT oxygen uptake and tissue perfusion will be measured using 15O-O2 and 15O-H2O PET-CT, at room temperature and after cold exposure. In addition, BAT glucose uptake will be measured using 18F-FDG after 2 hours of cold exposure and BAT NEFA uptake will be analyzed using 18F-FTHA at room temperature. To understrand the metabolic effects of BAT activation in individuals with obesity and how the cold water immersions affect the BAT perfusion in humans is critical for the development of new strategies to treat obesity and its comorbidities.
Children with obesity are prone to suffering from metabolic diseases, which undoubtedly increases the burden of public health. Since obesity is a multiple gene disease, a comprehensive approach using polygenic risk scores (PRS), rather than individual genetic variant, may be a more appropriate method. The aim of the study was to establish a polygenic risk score model to assess differences to assess differences in weight loss treatment outcomes.
This study will evaluate the effects of whole vs. nonfat milk consumption on body composition, cardiometabolic disease risk factors, and dietary quality.
The purpose of this research study is to understand why certain HIV medication regimens (called anti-retroviral or ARV medications) cause more weight gain than others. In this research, the investigators will compare micro-RNA profiles of people who take Symtuza(darunavir(D)/cobicistat(C)/emtricitabine(F)/tenofovir alafenamide (TAF))[D/C/F/TAF] with those who take Biktarvy(bictegravir(B)/emtricitabine(F)/tenofovir alafenamide (TAF))[B/F/TAF] and try to correlate this with the change in body weight and BMI over a course of 48 weeks. The investigators will also attempt to monitor the calorie intake of the participants in the two groups and correlate it with treatment-induced weight gain. Micro-RNAs are small molecules that are produced naturally in the human body, and which are responsible for modifying the expressions of genes. They have the potential to be used in diagnostic and therapeutic medicine and their putative role has been explored in many diseases across many clinical trials. By doing this research, the investigators hope to learn more about their role in HIV disease and its correlation with treatment-induced weight gain.
