Overweight and obesity are increasing dramatically worldwide and contribute substantially to the burden of morbidity and mortality. Obesity was considered in the past a relative contraindication for abdominal and pelvic laparoscopy surgeries due to the morbidity that is associated with it. Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging field in minimally invasive surgery. By incorporating the advantages of endoscopic surgery, the vNOTES approach avoids abdominal wall wounds and trocar-related complications, including reducing post operation pain.
The rate of caesarean section is higher among obese pregnant women, leading to increased morbidity in this already vulnerable population. Oxytocin is the main drug used in obstetrics to optimize progress of labour, but observational studies have suggested that its efficiency may be insufficient in obese women with usual doses. We design a randomised controlled trial to test the effect of an increased oxytocin dose on the rate of caesarean section in obese primiparous women with spontaneous or induced labour.
The primary objective of our study will be verify a possible improvement in arterial oxygenation in the obese patient undergoing robotic-assisted radical prostatectomy if the ventilation will be guided by electrical impedance tomography rather than peripheral saturation alone.
Magnesium sulfate has been shown to be a successful tool in a large number of clinical areas. Its benefits include neuroprotection, control of eclampsia / pre-eclampsia, control of intraoperative blood pressure, decreased neuroendocrine response during laryngoscopy and tracheal intubation and reduced levels of postoperative pain and consumption of analgesic. Obese patients have become more and more frequent in the operating rooms, due to the increasing prevalence of this population worldwide. However, although they have received magnesium sulfate as part of the analgesic strategy in many centers, there has been no study demonstrating the appropriate dose of this medication in obese patients. This study aims to compare two doses of magnesium sulfate in obese patients: based on their real weight or based on ideal weight.
The study investigates whether the addition of resolution molecules can inhibit inflammation and insulin resistance in human tissue taken from obese individuals, and whether the results of these studies correlate with patient-specific resolution phenotypes.
This is a rigorous, controlled clinical trial designed to show that diet, exercise training, and their combination in overweight, inactive men will alter epigenetic programming to create a "healthy" sperm epigenome. Our central hypotheses are: i) overweight and inactive lifestyle results in epimutations in the sperm epigenome relative to the normal epigenetic programming in lean and active men and ii) diet and exercise modulation leads to reversal of these epimutations resulting in both a healthier "phenotype" and "epigenotype" which may persist after stopping the interventions. The study is divided into three parts: 1. We will recruit 20 healthy, active men and 20 obese and inactive Hispanic men between 18 and 40 years to determine the differences in sperm epigenome (DNA methylation, histone modifications and non-coding RNAs) in a cross-sectional study in obese inactive vs. healthy active Hispanic men. Only Hispanic men will be studied because of the high prevalence of obesity and inactivity in Hispanic younger men and to reduce the genetic variability influencing the epigenome. 2. 80 obese and inactive men will be randomized to 4 groups of 20 men: 1) No intervention (control); 2) Low fat, low caloric diet; 3) Supervised, periodized endurance and resistance training without modification of diet; and 4) Both exercise and diet modification to characterize the plasticity of the sperm epigenome in response to 12-week diet and/or exercise training interventions in obese and inactive Hispanic men. Sperm epimutations will be compared before and after intervention within each group and between groups. 3. The sperm epigenome studies in 80 men randomized to no intervention or diet and/or exercise training will be repeated at 12 and 36 weeks after cessation of interventions to Identify the persistent effects of diet and exercise training on the sperm epigenome after stopping the interventions.
We propose to investigate effects of HP and HC weight loss diets in Newly Diagnosed T2DM (NT2DM) women and men for 6 months for remission of Type 2 Diabetes. Our long term goal is to establish a weight loss diet plan for remission of NT2DM which would be adaptable for use in physicians' clinics and metabolomics predictors for assessment of remission. The overall objective of this study is to determine if remission of NT2DM can be induced by dietary manipulation using a HP diet and the pathobiology of this remission. We hypothesize that NT2DM subjects will have remission to NGT on the HP diet when they are provided the food and daily menus for compliance. The rationale is the HP diet is palatable for subjects to continue after the 6 month study and stay in remission using diet plans we provide. We will compare the effects of the HP vs HC diet on remission. Specific aims of this study are to determine the effects of the HP and HC diets on NT2DM obese subjects in a 6 month feeding study and determine: (a)remission of NT2DM to Normal Glucose Tolerance(NGT), (b)weight loss, (c)improvements in metabolic markers, Cardiovascular Risk Factors(CVR), and inflammation markers, and epigenetic DNA methylation changes and pathways involved with remission and metabolomic markers to establish predictive markers of remission of NT2DM. We propose to use a non-pharmaceutical means (HP diet) for remission of T2DM and weight loss and determine the pathobiology involved in improvement in metabolic and CVRs by interrogating the samples with emerging technologies. The proposed research is significant because if we can demonstrate the HP diet cause remission of NT2DM to NGT along with other metabolic improvements, it would be a significant improvement in health risk and medical cost to subjects.
The weight reduction obtained after a first bariatric surgery would improve the vascular (correction of endothelial dysfunction, improvement of arterial wall compliance and evolution of the atherothrombotic process) and microcirculatory function in obese patients with type-2 diabetes.
Non-alcoholic fatty liver disease (NAFLD) is a condition of excessive hepatic lipid accumulation in subjects that consume less than 20g ethanol per day, without other known causes as drugs consumption or toxins exposure. In Western countries, the rate of this disease lies about 30% in the general adult population. The process of developing NAFLD can start from simple steatosis to non-alcoholic steatohepatitis (NASH), which eventually can lead to cirrhosis and hepatocellular carcinoma in the absence of alcohol abuse. Liver biopsy is considered the "gold standard" of steatosis, fibrosis and cirrhosis. However, it is rarely performed because it is an invasive procedure and investigators are focusing in the application of non-invasive liver damage scores for diagnosis. The pathogenesis of NAFLD is multifactorial and triggered by environmental factors such as unbalanced diets and overnutrition as well as by lack of physical activity in the context of a genetic predisposition. Nowadays, the treatment of NAFLD is based on diet and lifestyle modifications. Weight loss, exercise and healthy eating habits are the main tools to fight NAFLD. Nevertheless, there is no a well characterized dietary pattern and further studies are necessary. With this background, the general aim of this project is to increase the knowledge on the influence of nutritional/lifestyle interventions in obese patients with NAFLD, as well as contribute to identify non-invasive biomarkers/scores to early diagnosis of this pathology in future obese people.
