Active clinical trials for "Obesity"

This multi-national program applies a breakthrough approach to childhood obesity called, Brain-to-Society (BtS) Diagnostic Approach. In Montreal, Canada and Palwal, India, the investigators will recruit two cohorts of 612 children (6 to 12 years; 306 boy/306 girls) where Whole-of-Society (WoS) transformations are taking place (industrialized societal context with peaking childhood obesity and where a broad governmental plan to promote healthy lifestyle has been adopted -Canada; developing societal context with increasing childhood obesity if replication of past pathways that have lead to double burden; India) are taking place along with World Health Assembly (WHA) resolution A63-12 for marketing of food to children. Individual-level BtS Diagnostic will examine the degree to which individual differences in genetics and biology and differences in the environmental exposures modulate the behavioral, body weight/fatness and nutritional risk over time in the context of WoS transformations. Societal-level BtS Diagnostic shall examine the influence of decisions in policy, investment, business and innovation made by different stakeholders (government, private sector, civil society in health and non-health society systems including agriculture, business and media practices) on the community.

The very low carbohydrates diet (VLCKD) induces liver steatosis amelioration. Lysosomal acid lipase (LAL) deficiency plays a role in fats accumulation in liver. To date, no studies have assessed LAL activity in morbid obesity. The aim of our study is to evaluate VLCKD impact on metabolic/vascular parameters and LAL activity in obese patients. A VLCKD is administered for 25 days to 52 morbid obese patients (BMI 44.7±8.3 kg/m², age 49±12.5 years); at baseline and after diet we evaluated: BMI, glyco-lipidic pattern, abdominal ultrasonography (liver steatosis and visceral fat area) and flow-mediated dilation (FMD). In a subgroup of 20 patients we also tested lysosomal acid lipase (LAL)-activity. A group of healthy normal weight subjects (age 43±13, BMI 22.8±2.6 kg/m²) was also included in the study.

The purpose of this study is to determine the change in kidney function and blood pressure after gastric bypass versus conventional medical therapy in morbid obesity. The study mainly focus on glomerular filtration rate(GFR) with known relation to the renal function and 24 hours ambulatory blood pressure monitoring after intervention of gastric bypass or medical treatment.

The primary purpose of the study is to test the feasibility of a protocol of enhanced recovery after surgery for reducing the total length of hospital stay in a large scale setting

Before surgery, patients will fill the Beck anxiety, distress tolerance test and Pain katastrophizing test. Patients will be divided into two groups according to BMI> 30kg / m2 (Group A) and BMI <30kg / m2 (Group B). Compared to body weight, venous vascular pain of the groups will be compared.

This study seeks to correlate microbiome sequencing data with information provided by patients and their medical records regarding obesity.

Pediatric obesity is a risk factor for the onset of obesity in adulthood and is a risk factor for various chronic non-communicable diseases. Metabolic syndrome (MS) is the name for a group of risk factors that increase cardiovascular risk and other health problems characterized by the presence of abdominal obesity, dyslipidemia, hyperglycaemia and high blood pressure. Numerous preclinical and clinical data suggest a potential role of the intestinal microbiota in these diseaes. Unfortunately, comparative studies of the gut microbiota are still scarce in pediatric subjects suffering from obesity than obesity complicated by MS. The aim is to study the metagenomics and metabolomics characteristics of the intestinal microbiota in obese children/adolescents with or without MS, that could provide useful data for innovative intervention strategies for these conditions.

This is a cohort study where families with infants are followed closely for three years. It aims to assess if parental weight status (normal weight vs. overweight/obesity), their physical activity and eating habit will influence their young children's growth and be helpful in childhood obesity reducing.

In the United States cardiovascular disease (CVD) accounts for 1 in every 2.8 deaths and is the leading cause of death among men and women 65 years or older (1). Studies have shown that the risk for cardiovascular disease is higher in individuals with the Metabolic Syndrome (2). Metabolic Syndrome (MBS) is defined by the Adult Treatment Panel III (ATP III) guidelines as a group of risk factors that includes 3 or more of the following: abdominal obesity, hypertriglyceridemia, low high-density lipoprotein (HDL) cholesterol, high blood pressure, and high fasting glucose (3). These factors place individuals at increased risk for the development of both cardiovascular disease (CVD) and diabetes mellitus (3). It is commonly held that insulin resistance is the driving force for the development of the MBS. Although there is a significant increase in incidence of MBS in the elderly, there are few studies that specifically examined MBS in that population. The prevailing opinion is that the strikingly high prevalence of the MBS in the elderly is due to concurrent obesity - i.e., the population gains weight as it ages, and development of the MBS accompanies the weight gain. However, while it is true that becoming obese may decrease insulin sensitivity, it has also been demonstrated that not all obese individuals are insulin resistant. Some studies suggest that up to 40% of obese individuals demonstrate normal insulin sensitivity (4). In addition, it is notable that the rate of increasing MBS in the population exceeds that of the rate of increasing BMI, suggesting that, while BMI may be a modulating factor, another factor independent of obesity also contributes to the development of MBS in the elderly. It is the investigators hypothesize that the MBS in the obese elderly population is primarily linked to insulin resistance and not to obesity per se. The investigators propose to test this hypothesis by assessing MBS and insulin resistance in a population of obese elderly men and women and then determining whether or not the MBS tracks with insulin resistance.

The overall aim of the study is to investigate if patients with musculoskeletal chronic pain have reduced semen quality in comparison with age matched healthy controls. Secondly, the aim is to investigate whether overweight with or without chronic pain are related to reduced semen quality. We will investigate semen quality in obese chronic pain patients, normal weight chronic pain patients and in obese and normal weight healthy controls.
