Active clinical trials for "Metabolic Syndrome"

Along with the improvement of childhood acute leukemia treatment, survival rates have increased. Therefore, the number of long term childhood leukemia survivors has increased progressively over the last decades. So, the assessment of long term health status in this population becomes very important. Many studies have shown an increased risk of life threatening late complications and early mortality. Cardiovascular morbidity and mortality are particularly frequent. Among these late complications, the metabolic syndrome (MS) is an important concern since it is associated with cardiovascular morbidity and mortality. The overall MS prevalence in the French prospective cohort of survivors of childhood acute leukemia was 9.2% and 18.6% in cases of total body irradiation (TBI) during the leukemia treatment. Since the median age at MS evaluation was 21 years, this prevalence was very high. Anyway, the MS pathophysiology in this population is still poorly understood. One of the most recent hypothesis about the MS mechanism is based on the adipose tissue inability to store fatty acids: when adipose tissue cannot expanse further to store excess nutriments then lipids accumulate in other tissues. This ectopic lipids accumulation can cause insulin resistance and MS. The investigators hypothesized that the adipose tissue could be damaged by treatments received during childhood acute leukemia treatment (particularly TBI). This leads to morphological and functional abnormalities that could promote the insulin resistance and MS. This ectopic adipose tissue contains less preadipocytes, which could impair its functional properties. The primary endpoint of this study is to compare the morphological and functional characteristics of adipose tissue in patients with a MS who received or not TBI during childhood leukemia treatment . This comparison will focus on: The adipose tissue repartition and evaluation of the ectopic adipose tissue Fibrosis and inflammation of the adipose tissue Preadipocytes quantification The secondary endpoint is to describe: for the whole cohort of included patients, the clinical and biological characteristics associated with the MS. Cardiovascular risk factors and nutritional statement Anthropometric measurements Detection of other endocrinal abnormalities possibly associated with the MS Analysis of inflammation blood markers and adipokines quantification.

To evaluate the prevalence of lipodystrophy syndrome in patients receiving currently available antiretroviral drugs, and the prevalence of associated metabolic syndrome in HIV-infected patients with a previous diagnosis of lipodystrophy syndrome, according to the severity of fat accumulation and antiretroviral drug use.

The study is being conducted to test the ability of a simple questionnaire to detect mild, moderate or severe obstructive sleep apnea. The investigators are also investigating whether adding the size of the neck and waist can add to the accuracy of the questionnaire. The study will be conducted at the Center for Sleep Medicine at Tufts Medical Center. The investigators hope to enroll 250 patients in our study at Tufts Medical Center.

Patients with schizophrenia are more likely to have metabolic syndrome compared to general population. The criterion for metabolic syndrome in Asian people including: elevated waist circumference (male ≥ 90cm, female ≥ 80cm), elevated triglycerides ≥ 150mg/dL, reduced HDL cholesterol: male < 40mg/dL, female < 50mg/dL, elevated blood pressure: ≥ 130/85 mmHg, elevated fasting glucose: ≥ 100mg/dL. Several factors have been found to be associated with metabolic syndrome in schizophrenia, e.g. age, antipsychotic drugs, smoking, family history of metabolic disorder, stress, and quality of life. However, little is known about the prevalence of and factors associated in Asian. This study aimed to: Identify the prevalence of metabolic syndrome in patients with schizophrenia. Identify the factors associated with metabolic syndrome in patients with schizophrenia.

The purpose of this study is to find out if there is a connection between a higher level of peptide alpha defensin in blood serum with the metabolic profile of adolescents aged 13-17.

Rates of obesity and the metabolic syndrome are increasing in the young adult population (years 18-28). Modifying diet, especially increasing fruit and vegetable intake, can help assist in health maintenance and disease prevention. The purpose of this project is to evaluate the impact of the FRUVEDomics behavior intervention on dietary behaviors and metabolic parameters on young adults "at-risk" of disease. FRUVEDomics is an 8-week free-living dietary intervention, based on the USDA Dietary Guidelines for Americans and driven by the Social Cognitive Theory, conducted in young adults (18-28 years old) at West Virginia University. Individuals were recruited if they had pre-existing poor nutritional habits. A metabolic syndrome risk screening score was given to participants at baseline to measure "risk" status for chronic disease. Subjects were randomized into one of three nutritional intervention groups: 1) "FRUVED" (50% fruit & vegetable), 2) "FRUVED+LRC" (50% fruit & vegetable plus low refined carbohydrate), and 3) "FRUVED+LF" (50% fruit & vegetable plus low fat). Anthropometrics, surveys, venous blood samples and body composition were collected before and after the intervention. Group nutrition education including basic nutrition for the prescribed intervention, culinary tool kit distribution, sample budget and grocery shopping tips were delivered to each participant group prior to the start of the intervention. Participants underwent individual weekly consultations with a Registered Dietitian Nutritionist using food logs, food pictures and receipt management, to assess adherence and cost of the intervention.

Obesity is a chronic inflammatory disorder in which leptin, adiponectin and C reactive protein (CRP) play an important role. This study aimed to investigate the relationship between markers of adiposity like leptin, adiponectin and high sensitive C reactive protein (hsCRP) in obese children, and to determine whether these adipokines are significant markers in defining metabolic syndrome in pediatric population

Energy metabolism and insulin sensitivity were assessed in a case-control study in patients with branched-chain organic acidemias.

A growing number of cross-sectional studies is investigated the role of the human lipidome as a new biomarker for metabolic diseases. However, data on this issue is still sparse and especially interventional data is not available up to now. "GesundLeben" will provide data on 100 human subjects with metabolic syndrome, undergoing distinct types of lifestyle intervention for 6 weeks. Standardized metabolic assessment will be covered with routine laboratory parameters and oral glucose tolerance test as well as non-radiologic anthropometric measurements.

Metabolic syndrome is defined by the presence of at least two of the following five criteria: abdominal perimeter> 94 cm in men, 80 cm in women, high triglycerides, low HDL cholesterol, HTA and hyperglycemia. The metabolic syndrome can lead to ultrasound hepatic steatosis in 20 to 40% of cases depending on the population studied (overweight vs obesity). What is the impact of this syndrome on pancreatic echogenicity?
