The study is not related to any specific treatment options or pharmaceutical product. Collection of data will be performed via quantitative online survey by a third-party vendor. The goal of this study is to provide insights to drive awareness around the needs of People Living with Obesity (PLwO) and Health Care Professionals (HCPs) involved in obesity treatment and management.

NCT ID: NCT05642533 Enrolling by invitation - Clinical trials for Obesity and Cardiovascular Risk

Obesity and Cardiovascular Diseases, Cross-sectional Study in Saudi Arabia

Start date: December 31, 2022
Study type: Observational

The purpose of this research study is to collect information on participants body weight, blood sugar levels, heart related diseases and lifestyle. The collected information will help estimate the prevalence of participants disease. This study will take about 6 months. However, participants involvement in the study will not extend beyond their routine visit and will thus require a maximum of 1 day. If participants choose to take part, they will be asked to give information about their health in routine clinical visit. Participants will be asked to complete a questionnaire about their lifestyle. Participants will complete this questionnaire during their normally scheduled visit with their doctor. Participants will continue their normal way of life and will not get any medication other than those prescribed to them by their doctor. Participants will have no direct benefit from participation in this study and there are no risks involved. Participants decide voluntarily whether they want to participate in this study or not. Participants' decision will not affect their medical care and they do not have to justify their decision. Participants are free to leave the study at any time and without giving reasons. This does not affect their current or future treatment. The data collected up to that point are still being evaluated. There is no additional cost to participants for being in this study.

NCT ID: NCT05540314 Enrolling by invitation - Obesity Clinical Trials

Robotic Bariatric Database (RBD) Collaborative

Start date: August 10, 2022
Study type: Observational

With increased prevalence of obesity in the general population over the past 30 years, researchers have been focused on the development of new treatment options to achieve long-lasting weight loss. In 1991, the National Institutes of Health Conference Statement on Gastrointestinal Surgery for Severe Obesity developed a consensus stating that bariatric surgery was the most effective treatment for obesity since it is associated with good long-term results in terms of weight loss, glycemic control and decreased mortality. To collect and store clinical data related to the treatment outcomes of robotic bariatric surgery in order to develop an evidence base such that physicians can provide the best possible care to patients undergoing surgical weight loss interventions.

NCT ID: NCT05530356 Enrolling by invitation - Obesity Clinical Trials

Renal Hemodynamics, Energetics and Insulin Resistance: A Follow-up Study

Start date: September 30, 2022
Study type: Observational

The current protocol plans to enroll participants with youth-onset Type 2 Diabetes (T2D) as well as obese and lean controls from the Renal-HEIR - Renal Hemodynamics, Energetics and Insulin Resistance in Youth Onset Type 2 Diabetes Study (n=100) [COMIRB #16-1752] in a prospective investigation that seeks to 1) define the changes in kidney function by gold standard techniques and energetics by functional Magnetic Resonance Imaging (MRI) in adolescents with and without T2D as they transition to young adulthood; 2) quantify kidney oxidative metabolism by 11C-acetate Positron Emission Tomography (PET) in a subset of participants who are ≥18 years of age with youth-onset T2D and/or obesity; 3) determine peripheral arterial stiffness by SphygmoCor. Mechanistic insight will be provided by transcriptomic analyses of repeat biopsies 3-years after their initial biopsy for eligible participants with youth-onset T2D, as well as molecular analysis of tissue obtained from J-wire endovascular biopsies. This study will also leverage this well-characterized cohort of youths to define youth-onset T2D-related changes in brain morphology and function by structural MRI and resting-state functional MRI and through the assessment of cognitive function (fluid and crystallized intelligence) using the NIH Toolbox Cognitive Battery (NIHTB-CB), as an exploratory objective. All enrollees in Renal-HEIR have consented to be contacted for future research opportunities.

NCT ID: NCT05502692 Enrolling by invitation - Dolutegravir Clinical Trials

CHARACTERISE - A Cross-sectional, Observational Study to Characterise the Transition to Dolutegravir-based Regimens in South Africa in Terms of the Emergence of Obesity, Viral Re-suppression and Integration Into Routine Programme Care

Start date: July 12, 2022
Study type: Observational [Patient Registry]

The ADVANCE clinical trial compared three recommended first-line regimens two containing dolutegravir head-to-head and demonstrated virological non-inferiority at 48- and 96-weeks respectively1,2, paving the way for the mass- introduction of dolutegravir-containing regimens across low- and- middle-income countries. The dolutegravir-containing regimens in ADVANCE were very well tolerated and demonstrated remarkable viral re-suppression in patients with viraemia when adherence measures were instituted, even in the presence of genotypically-documented resistance1,2. Across Africa, including South Africa, and in many other low- and middle-income countries, the combination of tenofovir disoproxil fumarate/lamivudine (or emtricitabine) /dolutegravir has been rolled out to millions of patients, much of this with Unitaid support to research, programmes and communities. Most ADVANCE patients have since transitioned out of the study and are on tenofovir disoproxil fumarate/lamivudine/dolutegravir in South African public sector clinics in central Johannesburg. One of the unanticipated findings of ADVANCE and the concomitant Unitaid-supported NAMSAL3 study in Cameroon, as well as analyses of registration studies and observational studies, was the consistent finding that patients on dolutegravir experience significant weight gain and new-onset obesity. It remains unclear whether this is a feature of the integrase inhibitor class (and aggravated by tenofovir alafenamide), or whether other factors are at play - it is possible that HIV infection itself may predispose to weight gain in successfully treated patients, and other antiretrovirals may alter weight trajectories. The signal has been met with alarm by the public health community, as many countries where TLD is being rolled out are experiencing a parallel obesity epidemic. Obesity is strongly associated with adverse outcomes, including diabetes, cardio-vascular-disease (CVD), sleep apnoea, gastrointestinal and muscular-skeletal disorders, asthma, poor pregnancy outcomes, many cancers, mental health issues, and poor COVID-19 outcomes. In many countries with large antiretroviral programmes, these concurrent epidemics have significant public health and financial implications, and clarification of the extent of the obesity signal is urgent.

NCT ID: NCT05486169 Enrolling by invitation - Obesity Clinical Trials

Gastroesophageal Reflux Disease After Laparoscopic Sleeve Gastrectomy

Start date: September 1, 2022
Phase: N/A
Study type: Interventional

The planned research is to analyze the occurrence of gastroesophageal reflux disease (GERD) before and after sleeve gastrectomy (SG). The study includes patients with BMI above 40 kg / m2 without symptoms of GERD before surgery and any pathological changes in gastroscopy. The day before the surgery, patients will be tested with impedance pH measurement. Thereafter, patients will undergo SG according to standard technique. As part of the follow-up 6 months after the surgery, the pH-measurement test with impedance again will be performed again for evaluation of the occurrence of GERD after surgery. It was planned to include 50 people in the study. The main aim of the study is to assess the frequency and quality of GERD in patients after SG.

NCT ID: NCT05459675 Enrolling by invitation - Obesity Clinical Trials

Effects of Very Low-calorie Diet Versus Bariatric Surgery on Body Composition and Gut Microbiota Pattern

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

Obesity is a chronic disease characterized by the excessive accumulation of fat in body and it continues to be a major public health problem worldwide. Treatment options for obesity include lifestyle modification, pharmacotherapy and bariatric surgery. Bariatric surgery is a highly effective treatment for obesity and results in rapid and sustained weight loss. Also, it significantly alters gut microbiota composition and function. A very low-calorie diet (VLCD) is a rapid weight loss program which calorie intake is severely restricted (< 800 kcal/day). It has been shown to be very effective to induce rapid weight loss and result in comorbidities resolution similar to bariatric surgery. Therefore, this study was aimed to study the effects of 12-week VLCD compare to bariatric surgery (Laparoscopic Roux-en-Y gastric bypass (LRYGB) or Laparoscopic Sleeve Gastrectomy (LSG)) on weight loss, body composition, gut microbiota pattern and other metabolic parameters.
