NCT ID: NCT05781269 Recruiting - Obesity Clinical Trials

Long Term Effect of Very-low-calories Ketogenic Diet on Weight Control and Cardiovascular Brisk Factors (KETOHEART)

KETOHEART
Start date: February 20, 2022
Phase: N/A
Study type: Interventional

The growing obesity pandemic has a major impact on global cardiovascular (CVD)-related morbidity and premature mortality, severely compromising the quality of life of those affected and significantly increasing costs for the healthcare system. Numerous scientific evidences have demonstrated that a moderate weight loss (5-10% of the initial body weight) is already sufficient to determine the improvement of the cardiometabolic risk factors associated with overweight and obesity. With a view to obtaining a more significant weight loss in the initial stages of dietary treatment, in the last 10 years, the very low-calorie ketogenic diet (VLCKD) has become a strategy for the treatment of obesity and its comorbidities, also allowing to limit therapeutic failure and the high drop-out typical of traditional low-calorie diets. The present study aims to study the long-term efficacy (36 months) of VLCKD in patients with severe obesity and metabolic syndrome, on weight loss, on single factors of the metabolic syndrome compared to a restrictive Mediterranean diet. One hundred subjects with severe obesity and metabolic syndrome will be recruited and randomly assigned to VLCKD or to restrictive Mediterranean diet. Anthropometric parameters, metabolic status blood pressure, degree of arterial stiffness, prevalence and severity of snoring and OSA, cardiac systolic and diastolic function, the autonomic nervous control mode of the circulation will be evaluated at baseline, after one month and at the end of the study.

NCT ID: NCT05710263 Recruiting - Morbid Obesity Clinical Trials

Bariatric Embolization Before Sleeve Gastrectomy for Super Obese Patients

EMBOSLEEVE
Start date: January 10, 2023
Phase: N/A
Study type: Interventional

In patients with severe obesity, bariatric surgery provides consistent and long-term weight loss. BMI ≥50kg / m2 is an independent factor of increased morbidity / mortality in bariatric surgery compared with patients weighing less than 50 kg / m2 (1.2% and 0.8%) mainly due to technical difficulties. Preoperative weight loss reduces this morbidity / mortality. Recent studies have shown that blocking blood vessels to a particular portion of the stomach (bariatric or left gastric artery embolization) can temporarily decrease levels of the appetite inducing hormone ghrelin, and result in weight loss. The purpose of this study was to evaluate the safety and effectiveness of the association bariatric embolization before sleeve gastrectomy in super obese patients.

NCT ID: NCT05680909 Recruiting - Morbid Obesity Clinical Trials

Evaluation of SaCo Videolaryngeal Mask Airway in Morbidly Obese

Start date: May 20, 2022
Phase:
Study type: Observational

SaCo videolaryngeal mask airway is a novel third generation supraglottic device allowing for continuous observation of entrance to larynx via inserted in special channel videoscope connected with cable with external monitor. In obese patients airway management can be difficult so use of new devices that improve safety and potentially efficacy of airway management is indicated. In prospective observational study the SaCo VLM will be evaluated in terms of maintaining airway patency and effectiveness of intubation through it's lumen in morbidly obese scheduled for elective general surgery under general anesthesia.

Ondansetron and Gabapentin in Preventing Postoperative Nausea and Vomiting After Laparoscopic Sleeve Gastrectomy

Start date: October 1, 2022
Phase: Phase 3
Study type: Interventional

The aim of this study is to compare the possible efficacy of ondansetron and gabapentin on postoperative nausea and vomiting in patient with morbid obesity who will undergo laparoscopic sleeve gastrectomy.

NCT ID: NCT05569681 Recruiting - Morbid Obesity Clinical Trials

Two Different Regimens of Bemiparin as a Thromboprophylaxis in Morbidly Obese Surgical Patients

Start date: January 7, 2023
Phase: N/A
Study type: Interventional

Morbid obesity, is known to be associated with a high risk of VTE and, unfortunately, fixed doses of anticoagulant regimens may not provide optimal VTE prophylaxis in these patients especially after surgery.

NCT ID: NCT05537883 Recruiting - Morbid Obesity Clinical Trials

Transversus Abdominis Plane (TAP) Block Using Liposomal Bupivacaine in Metabolic and Bariatric Surgery Patients

TAP
Start date: November 29, 2022
Phase: Phase 1
Study type: Interventional

To investigate if laparoscopic Transversus Abdominis Plane (TAP) block using plain bupivacaine is equivalent to using liposomal bupivacaine in patients undergoing metabolic and bariatric surgery. The study will see if the plain bupivacaine group will be equivalent in terms of length of stay, Morphine Milligram Equivalents, Pain scores and patient satisfaction, but cost less.

NCT ID: NCT05529563 Recruiting - Insulin Resistance Clinical Trials

The Effect of Laparoscopic Sleeve Gastrectomy on Insulin Secretion Pattern in Morbidly Obese Patients With Acanthosis Nigricans

Start date: June 1, 2017
Phase:
Study type: Observational

Acanthosis nigricans (AN) is increasing in its prevalence and is the most prevalent cutaneous manifestation in individuals with obesity. Insulin resistance or hyperinsulinemia is the main pathophysiological mechanism of obesity-related AN. However, the effect of laparoscopic sleeve gastrectomy (LSG) on insulin secretion pattern in Chinese morbidly obese patients with AN is unknown. In these study, the investigators aimed to explore the insulin secretion patterns in Chinese morbidly obese patients with Acanthosis nigricans (AN) and their alterations after LSG.

NCT ID: NCT05000996 Recruiting - Hypertension Clinical Trials

Gut Microbiota in Metabolic Surgery

Start date: August 19, 2021
Phase:
Study type: Observational [Patient Registry]

Metabolic surgery is an emerging option to treat obesity-related metabolic diseases (e.g., type 2 diabetes) and prevent cardiovascular disease (CVD). Metabolic surgery can profoundly alter the gut microbiota; meanwhile, gut microbiota may affect surgical outcomes. Longitudinal studies that examined pre- to post-surgery changes in gut microbiota and its relation to cardiometabolic health after surgery are limited. Furthermore, few studies have included African Americans, a population with high rates of cardiometabolic diseases. The investigators aim to fill these research gaps by establishing a longitudinal, observational study of metabolic surgery patients and applying multi-omics to identify stool, blood, and/or tissue microbial features related to post-surgery cardiometabolic outcomes. In the current study, the investigators plan to enroll up to 300 patients who undergo metabolic surgery at Vanderbilt University Medical Center and follow them for up to 10 years after surgery. Fasting blood and stool samples will be collected at pre-surgery and 3-month, 1-year, 2-year, and 3-year post-surgery clinical visits. Tissue samples (e.g., biopsies of the liver and adipose and remnants of the stomach) will be collected during operation. Meanwhile, participants will complete a REDCap survey at baseline and 1-year, 2-year, and 3-year post-surgery. Participants' electronic medical records will be used to obtain additional information and facilitate long-term follow-up. The investigators will evaluate pre- to post-surgery changes in the fecal microbiome and fecal and blood levels of metabolites and proteins and the associations of microbiome, metabolites, and proteins with cardiometabolic improvements after surgery. This study will advance our understanding of the role of gut microbiota in metabolic surgery, which may translate into novel approaches to identify and treat obese patients for better cardiometabolic health.
