Active clinical trials for "Obesity"

Backround:The incidence of difficulty in laryngoscopy and endotracheal intubation is more common in obese patients. There are conflicting data on factors predicting difficult intubation. Also, these predictors are uncertain when video laryngoscopy (VL) is used. In this study we aim to investigate the correlation between airway assessment tests, anthropometric measurements and Modified Cormack-Lehane Classification (MCLC), assessed by C-MAC-D-blade VL and predictive values for intubation difficulty in class-III patients. Methods: This prospective observational study was performed in 121 obese patients (Body mass index (BMI)≥45kg/m2) undergoing bariatric surgery. BMI, modified mallampati scores (MMS), thyromental distance (TMD), sternomental distance (SMD), interincisor distance (IID), and neck, waist, and chest circumference were all recorded preoperatively. Endotracheal intubations were performed with a C-MAC D-blade VL. The glottic view and intubation difficulty were determined according to the MCLC. MCLC I-IIa was recorded as the group with no risk of a difficult intubation, the MCLC IIb-III was recorded as the group with risk of a difficult intubation and the MCLC-IV was recorded as the group with a difficult intubation. The correlation between the airway tests, anthropometric parameters and the MCLC, as well as their sensitivity and specificity in predicting the intubation difficulty based on the MCLC, were analyzed. The duration of intubation, number of attempts, external laryngeal maneuver, the equipment requirements (style, guide), and complications during intubation were recorded.

ACTION Switzerland is a cross-sectional, observational, descriptive, and exploratory survey-based study without collection of laboratory data. 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.

Background: - Popular weight loss plans often restrict carbohydrates or fat. Research shows that very-low-carbohydrate (ketogenic) diets lead to greater weight loss than low-fat diets. Researchers want to know if eating fewer carbohydrates changes the number of calories the body uses. They also want to know how a ketogenic diet affects hunger, hormones, and food preferences. Objectives: - To better understand how the body responds to different diets. Eligibility: - Men 18 to 50 years old who are healthy but overweight. Design: Participants will have 3 screening visits: Medical history, physical exam, blood test, and EKG. They will eat during the visit. For the week before the visit, participants will wear physical activity monitors daily. They will record everything they eat and sample the special diet. At the visit, they will receive an EKG and heart rate test while biking for 30 minutes. For the week before the visit, participants will wear the physical activity monitors. They will eat all their meals from the special diet that will be provided. At the visit, they will answer questions and bike for 60 minutes. After screening, for 1 week, participants will visit the clinic daily to receive that day s food. They will not eat or drink anything else except water. Then participants will stay at the clinic for 8 weeks. They cannot leave but can have visitors. Participants will wear physical activity monitors, bike daily, and follow different diets. Tests will be given daily, and may include weighing, X-rays, and blood and urine tests. They will spend several days in a monitored room to test oxygen and carbon dioxide.

This project examines behavioral and household characteristics associated with food purchasing patterns.

Mutations in the melanocortin 4 receptor (MC4R) are the most common form of monogenic obesity, and can explain 2-6% of severe obesity. Studies have shown that mutations in MC4R are associated with increased fat mass, height-for-age, appetite and insulin resistance among children. In adults, mutations in MC4R are less penetrant for these phenotypes but it has been observed that individuals with MC4R mutations have a smaller than expected blood pressure for their degree of obesity. The purpose of this study is to explore the association between functional MC4R mutations and obesity, insulin resistance and blood pressure.

This study will test the potential of two techniques using light properties of adipose tissue to diagnose crown-like structures and inflammation to be compared with pathologic examination of adipose tissue biopsies from ongoing clinical studies.

The primary objective of this pilot study is to characterize the profile of lipoprotein, inflammatory, and metabolic markers of cardiovascular disease in obese adolescents as compared to normal-weight age-matched controls.

To examine the influence of obesity on brain activation during food cue, stress, and neutral relaxing conditions

Childhood obesity is a major public health issue, and the identification of children who are at increased risk of health problems due to their obesity is a priority for modern health care. Abdominal fat is considered to be the most harmful in the body, and the development of reliable landmarks and procedures for the assessment of intra-abdominal visceral adipose tissue and total body fat in children will have a major impact on 1) the early identification of children at elevated health risk, 2) the proper prioritization of health care resources, and 3) the standardization of obesity surveillance procedures within and between countries.

An altered gut microbiota composition has recently been linked to obesity and diabetes. The principal aim of this study was to investigate and compare the gut microbiota composition of obese, diabetic and control individuals. Then, associations between analyzed gut microbial concentrations and clinical-biochemical blood parameters were assessed.
