NCT ID: NCT03768245 Completed - Obesity Clinical Trials

School-Based Program On Metabolic Disease

Start date: July 1, 2016
Phase: N/A
Study type: Interventional

Mexico occupies the first place worldwide in childhood obesity. Its urban and indigenous communities present different levels of westernization which have triggered different epidemiological diseases. This study aims to treat and prevent obesity and related diseases. A school-based multi-component intervention program is developed in three ethnic groups with varying levels of westernization: Mestizos, Seris and Yaquis. Measurements are obtained to evaluate obesity, cardiovascular, diabetes risk, hepatic and renal function, and physical fitness. The intervention consists on Physical Activity (PA), Health Education (HE) and Nutrition (NP) programs carried out in six urban (Mestizo ethnic group) and indigenous schools (Seri and Yaqui ethnic groups). A total of 800 participants were part of the PA and HE programs (Education Arm), and 117 of them were also part of the NP program (Nutrition Arm). Measurement differences, after and before treatments are used to assess the intervention effect by age, sex, ethnicity, nutritional status, and treatments. Expanded access is not applicable to this study. The Government's Secretary of Education does not allow developing a plan to share individual data of participants.

NCT ID: NCT03755674 Completed - Obesity Clinical Trials

CHRONOtype-adjusted DIET on Weight Loss

Start date: January 10, 2015
Phase: N/A
Study type: Interventional

BACKGROUND: Several reports have observed that the alteration of normal biological rhythms is associated with obesity development. In this regard, those subject with the preference for evening seems to be prone to develop obesity. However, the current treatment of obesity does not take into account these aspects OBJECTIVE: To evaluate whether a diet adjusted to patient's chronotype is more effective than the current dietary recommendations. SUBJECTS/METHODS: 209 subjects take part in a randomized, double-blind clinical trial. 104 subjects followed a typical hypocaloric dietary treatment (CONTROL) and the other 105 subjects undergone a diet with a daily caloric distribution adjusted to their chronotype (CHRONO). CONCLUSIONS: A chronotype-adjusted diet may be a promising alternative to the classical hypocaloric dietary treatment since the investigator's data indicate a higher effectiveness regarding weight loss when the diet was adjusted to the patient's chronotype.

NCT ID: NCT03752359 Completed - Healthy Clinical Trials

Start date: March 13, 2017
Phase: N/A
Study type: Interventional

The main purpose of the present study was to investigate the effects of whey protein following resistance training on body composition, muscular strength, functional capacity, and plasma-metabolism biomarkers in older women with sarcopenic obesity.

NCT ID: NCT03750604 Completed - Urologic Diseases Clinical Trials

Central Obesity in Cases of OAB

Start date: January 1, 2017
Phase: N/A
Study type: Interventional

Obesity is not a homogeneous condition and that the regional distribution of adipose tissue is important to understanding the relation of obesity to disturbances in glucose and lipid metabolism. Central abdominal fat is composed of abdominal subcutaneous fat and visceral fat. Regional distribution appears to be an important indicator for metabolic alterations since an inconstant correlation between body mass index (BMI) and these disturbances have been found. Visceral obesity is associated with increased adipocytokine production, proinflammatory activity, deterioration of insulin sensitivity, increased risk of developing diabetes, "high-triglyceride/low-HDL cholesterol dyslipidemia," hypertension and atherosclerosis. It might be more precise to divide central abdominal fat into subcutaneous(S) and visceral (V) fat surface area and volume and even ratio (S/V); risk factors for cardiovascular disease, particularly those related to glucose and lipid metabolism and hypertension, being>0.4; with evaluation of visceral fat functionality by visceral adiposity index (VAI) with integration with lipid profile. Adding bladder wall thickness with perivesical fat as a factor may impair bladder function and contribute to dysregulation. The data on the association between central adiposity with OAB symptoms and Urodynamics is not mature.

NCT ID: NCT03749772 Completed - Clinical trials for Overweight and Obesity

Cognitive Therapy Plus Dietary Intervention for Obesity Treatment

Start date: February 1, 2016
Phase: N/A
Study type: Interventional

This randomized clinical trial was carried out from January 2017 to December 2017 at the facilities of the Catholic University of Murcia. Written informed consent was required from each patient. The protocols of the present clinical trial follow the CONSORT standards. To measure the impact of cognitive training on weight loss in overweight / obese subjects, a double-blind study (de facto masking) was designed. Both the participants and the statistical assessors were unaware of the study hypothesis. Participants were unaware of treatments and possible assignments between groups, and only those subjects who were randomly assigned to the cognitive training group were informed that such training was part of dietary therapy. The principal investigator of the present study (J.J.H.M.) carried out the randomization, with the assistance of the Microsoft Excell program, with the help of a macro designed in Visual Basic® for that purpose. The randomization divided the subjects into two groups, as they were treated with a hypocaloric diet plus 12 nutrition education sessions (CONTROL group) or a group that were treated with a hypocaloric diet plus 12 sessions of cognitive training (COGNITIVE group). In order to obtain a similar size in both groups, a randomization in blocks with a 1: 1 allocation ratio was performed. Cognitive performance measures were performed before and after training. One week before the beginning of the cognitive and dietary intervention, the participants performed a series of cognitive tests. After 12 weeks of both dietary and cognitive intervention, participants were reexamined to measure performance on neurocognitive tests.

NCT ID: NCT03727607 Completed - Obesity Clinical Trials

TIVA Versus Desfluran Anaesthesia in Patients Undergoing Bariatric Surgery

Start date: January 30, 2016
Phase: Phase 2
Study type: Interventional

Many factors during laparascopic surgery leads to PONV (postoperative nausea and vomiting), such as C02 insufflations causing peritoneal stretch and irritation and type of anaesthesia given during surgery. The two anesthetic techniques used in bariatric surgery are gas anesthesia (Remifentanil TCI and Desfluran) and Total Intra Venous Anesthesia (TIVA) with propofol. There are studies which have shown a reduction in postoperative nausea and vomiting following TIVA, and there are publications showing no statistically significant difference. The aim of this study was to investigate the best anaesthetic approach for obese subjects, evaluating awakening time, postoperative nausea and pain. Our hypothesis was based on the fact that Propofol is a lipid-soluble anesthetic and therefore might have a prolonged effect in obese patients, leading to a longer awakening time along with postoperative nausea and vomiting. This hypothesis is also described earlier by obese patients have more depots (bulk fat) and also more fat surface making anaesthetics storage more easier, and also that the anesthetic will return into the circulation when the administration is stopped [18].

NCT ID: NCT03726567 Completed - Obesity Clinical Trials

Environmental Chemicals That Accumulate in Fat

Start date: October 12, 2012
Phase: N/A
Study type: Interventional

A crucial factor in evaluating the risk of dioxins, and related endocrine disruptor compounds (dioxins for short) in the human population is the accumulation of these chemicals in the human body. Human data on tissue background levels is extremely limited, and there are no studies in UK populations, although there are several European studies looking at blood levels of dioxins. Adipose tissue concentrations were 139 ng of TEQ (total dioxin-like compounds) per kg lipid weight (5.4 ± 4.6 ng of TCDD per kg lipid weight). However, given the different dietary habits of Japanese populations, compared to European populations, these estimates may differ considerably from UK values. Thus determining human tissue concentrations of dioxins is an important issue for assessing the risk to public health from these compounds, and this information is currently lacking for European populations. This information will also guide and inform the necessity fro continued measures to reduce the environmental dioxin levels in the UK. Aims Primary outcomes: 1. Investigation of the toxicodynamics of/dioxin distribution in adipose of a morbidly obese and comparative control population 2. Characterisation of the burden of dioxins in liver and adipose tissue, and the relationship with blood levels of dioxins, in a UK population Secondary outcome: Determining whether bariatric surgery-induced weight loss causes an increase in tissue concentration of dioxin-like compounds The primary aims of this study will yield useful information to refine the risk assessment process for the obese population. Experimental Methodology This proposal seeks to examine thirty non-obese patients taking liver (500mg) and adipose tissue (visceral and subcutaneous: 40g each) samples at the time of gastric/abdominal surgery; and thirty obese patients, taking liver (500mg) and adipose tissue (visceral and subcutaneous: 40g each) samples at the time of undertaking Roux -en-y bariatric surgery. Weight and bioimpedance and a food diary will be performed prior to surgery. A further body weight and bioimpedance will be undertaken at 3, 6, 9 and 12 months from the obese population. A subcutaneous adipose biopsy will be taken under local anaesthetic from these individuals at after bariatric surgery (minimum of 10% body weight loss). A record of weight loss since bariatric surgery will documented with the change in body composition. The statistical power for seeing an effect of gastroplasty, assuming a coefficient of variation of TEQ measurements of 75% and an increase in TEQ of two-fold, is 90% at P<0.05 for a population of thirty individuals. Should subjects need additional surgery (eg. cholecystectomy, diagnostic laproscopy) either as a consequence of bariatric surgery or for any other reasons during the 24 month following initial operation, a liver biopsy and visceral fat biopsy will be taken during the future surgery. If subjects undergo abdominal wall surgeries (eg. Apronectomy, ventral hernia repair) in the 24 months following initial bariatric surgery, an subcutaneous fat biopsy will be taken during the future surgery.
