Filter by:This study involves collecting real-world data on body weight, body composition, cardiovascular parameters, and neurovegetative parameters using a connected scale in patients with severe obesity treated with Wegovy®.
This is an retrospective and prospective (ambispective) study with data collection from volunteer patients who passed an MMPI-2-RF (Minnesota Multiphasic Personality Inventory-2-Restructured form) questionnaire in the preoperative phase of a bariatric surgery project. The evolution of their BMI will be correlated to psychological dimensions collected in patient questionnaires, before and after bariatric surgery. The presence of possible risk factors such as depression, anxiety, eating disorders, quality of life, satisfaction and the perception of body, could make it possible to establish adapted therapies before surgery, in order to attenuate or eliminate the presence of these factors, and improve BMI evolution and bariatric surgery success.
Bariatric Surgery for morbid obesity is indicated when BMI > 40 kg/m2 without comorbidities or BMI > 35 kg/m2 with co-morbidities. Different surgeries performed for obesity are classified as restrictive, malabsorptive, and hybrid procedures. Because laparoscopic surgery has increased the interest and growth of bariatric surgery, soaring demand for laparoscopic bariatric surgery from patients has boosted the boom in bariatric surgery worldwide. Achieving pneumoperitoneum is the initial and one of the most crucial steps in any laparoscopic surgery, giving the surgeon working space to operate on a particular organ/organ system. Usually, pneumoperitoneum is achieved either by a closed technique with a veress needle or an open technique with many variations like finger assisted or the conventional open technique. Given the excess amount of subcutaneous fat in morbidly obese patients, putting a veress needle to achieve pneumoperitoneum successfully is particularly challenging which takes a toll on the operating surgeon when he/she is trying to locate the midline one can either overshoot to cause omental emphysema or undershoot getting lost in the subcutaneous fat. It is usually done in the supra umbilical area. Sometimes, due to previous surgical scars other sites are preferred. Sonography is routinely used by radiologists with negligible radiation exposure. Anesthesiologists in the operating room have used it for many assisted procedures like central line insertion / giving nerve blocks. It can also be used in obese patients undergoing metabolic surgery to assist in creating pneumoperitoneum by a veress needle. Advantages of Intraoperative ultrasonography in this particular study : 1. To quantify the thickness of subcutaneous fat 2. To visualise the linea alba and guide the veress needle safely into the peritoneal cavity 3. Real-time visualisation of the pneumoperitoneum created 4. Avoid complications like omental emphysema, bowel or vascular injury
This study will investigate whether an ultrasound-assisted technique is better than a classical land-mark technique to facilitate spinal anesthesia in the sitting position in super obese pregnant women with BMI ≥ 50 who will undergo elective cesarean section. The primary objective of this study is the rate of successful dural puncture at the first attempt. It was assumed that ultrasound could facilitate neuraxial blockade in super obese (BMI ≥ 50 kg/m2), pregnant women, according to the Who classification, whose topographic anatomy is difficult.
The investigators aimed to compare the effects of using enotracheal tube with stylet versus endotracheal tube alone in morbidly obese patients undergoing sleeve gastrectomy.
This study aims to evaluate the nutritional status of morbidly obese patients following gastric bypass surgery. Data from 76 patients aged 19-64, who will be monitored by a dietitian for at least six months, will be analyzed. Preoperative and postoperative biochemical parameters along with anthropometric measurements will assess.
Obesity is associated with type 2 diabetes (T2D) and cardiovascular disease (CVD). Metabolic and bariatric surgery (MBS) has in several randomized controlled trials (RCT) been shown to be superior to best medical therapy in the treatment of T2D. In the area of CVD, RCT after MBS are lacking. It was recently demonstrated in a cohort study that MBS in patients with severe obesity and a previous myocardial infarction (MI) was associated with a 50% reduction in the risk of death and new MI. The aim of this proposal is to confirm this in a nationwide RCT. Using the nationwide SWEDEHEART database patients with severe obesity and a previous MI will be identified. They will be contacted and offered participation. After informed consent the patients will be randomized to MBS or optimized care (including visit with a cardiologist and optimization of secondary preventive measures and referral to dietician/physiotherapist). The primary outcome measure is a major cardiovascular adverse event (MACE). Secondary outcome measures include mortality, new MI, stroke, heart failure and atrial fibrillation. Tertiary outcome measures include health related quality of life and surgical complications. Patients will be followed in the nationwide metabolic surgery register SOReg, the national inpatient register, national cause of death register, the Swedish prescribed drug register, and the Swedish population register. If positive results these can be included in guidelines for MBS.
The aim of this observational study is to evaluate the actual secretion of cortisol and testosterone in obese male subjects, together with the receptor sensitivity to these hormones in order to understand whether the hormonal milieu deriving from these parameters is associated with alterations in bone metabolism, lipoprotein concentration and function, and/or the severity and complications of obesity. It will be also investigated if this hormonal milieu is a predictive factor for cardiovascular disease in obese patients. Eligible subjects are male patients (age 18-80 years) with severe obesity and no other known causes of hypercortisolism or hypogonadism. Questionnaires for the evaluation of mood and symptoms will be collected upon enrollment, patient's anamnestic and clinical data relating to disease complications, BMI, previous blood tests, cortisol suppression with dexamethasone 1 mg will be collected, and blood sample will be sent to and analyzed at a centralized laboratory for the study of Steroid hormones, bone metabolism, lipoprotein function, genetics and receptor analysis.
Background: Ketosis after bariatric surgery is a metabolic process that occurs when the body breaks down fat for energy because of not getting enough carbohydrates. Insufficient production of ketone bodies reduces the rate of weight loss, and excessive amounts of ketones can lead to ketoacidosis or liver failure in patients with nonalcoholic steatohepatitis (NASH). The investigators hypothesize that weight loss is directly related to calorie intake, and a significant reduction in carbohydrate content leads to increased ketosis and the risk of ketoacidosis. Objectives: The study aimed to compare the incidence of ketoacidosis and liver failure in patients with NASH with different intakes of carbohydrates in the early postoperative period after gastric bypass. In addition, the investigators want to find out how carbohydrate restriction will affect weight loss for up to 1 year.
United Kingdom National Bariatric Surgery Registry (NBSR) records between 1st June 2017 and 23rd November 2022 were used to identify people undergoing primary bariatric (weight-loss) surgery. People undergoing primary bariatric (weight-loss) surgery with one baseline and at least one follow-up visit within one year from surgery were included. Statistical models were used to estimate the relationship between quality of life as assessed by a questionnaire and body mass index at baseline and over time.
