Filter by:BACKGROUND: Binge eating disorder (BED) is the worldwide most-prevalent eating disorder. It is associated with psychiatric comorbidities and obesity, a high impact in life functioning, and high morbidity and mortality. First symptoms appear frequently in youths, who most commonly present incomplete (subthreshold) criteria for BED (precursor forms, PREC-BED). While some subjects will evolve from PREC-BED to BED, there is no gold standard to identify the clinical evolution. Information from prior studies suggest early alterations in reward and inhibitory brain circuits in PREC-BED may predict increased vulnerability or resilience to develop BED. Tools based on MRI brain connectivity analyses (MRI-BC), built on robust and interpretable connectivity whole-brain models, have proven successful in diagnostic classification and predicting certain clinical outcomes. OBJECTIVES: To study MRI-BC diagnostic markers of PREC-BED and to explore prognosis at 1 year of follow-up in a sample of adolescents with obesity (12-17 years old). METHODS: A) Transversal analytical design: 3-group (n=34 per group) comparison of neuroimaging (MRI-BC), neurocognitive and clinical markers in adolescents with obesity and i) BED, ii) PREC-BED, iii) no BED nor PREC-BED (Healthy group, HC). B) Longitudinal analytical design, pilot, exploratory: adolescents with PREC-BED will be evaluated in clinical and neurocognitive variables at 1 year. Baseline brain neuroimaging variables (alone and in combination with clinical and neurocognitive variables) will be analyzed as predictors of clinical prognosis, including conversion to BED.
The main purpose of this study is to determine if retatrutide can significantly lower the incidence of serious heart-related complications or prevent the worsening of kidney function. The trial will enroll adults with body mass index 27 kg/m^2 or higher and Atherosclerotic Cardiovascular Disease and/or chronic kidney disease. The study will last for about 5 years. Participants will have up to 27 clinic visits with the study doctor.
The overall aim is to identify the dietary pattern for prevention and treatment of type 2 diabetes. The specific aim of this pilot project is to compare effects of two diets with different diurnal distribution of carbohydrates and protein on the glucose metabolism in subjects with prediabetes and type 2 diabetes and its effects on inflammatory status.

The epidemic of overweight and obesity presents a major challenge to chronic disease prevention and health across the life course around the world. [1] Bariatric surgery has proved to be an efficient intervention in the management of obesity. As a result, the number of post-bariatric surgery patients in the population is growing [2]. Postoperative analgesia presents various challenges in vulnerable patient groups suffering from obesity. With the high potential risk of respiratory depression and postoperative pulmonary complications associated with opioid use, such as atelectasis and pneumonia, the availability of other pain management modalities is essential [14]. Ultrasound-guided erector spinae plane block (ESPB) is a regional anesthesia technique where local anesthetic agent is injected deep to the erector spinae muscle to fascial plane and allowed to diffuse caudally and cranially. It is supposed to provide both visceral and somatic abdominal analgesia [3]. ESPB is effective, easy to perform, and can be performed in a short time. [4] It has been shown efficacy in different conditions such as thoracic surgery, trauma, cardiac surgery, breast surgery, and abdominal surgery [5]. However, the main concern with the ESPB block is feasibility together with the potency of the block in challenging populations, such as patients suffering from obesity. Peripheral nerve blocks in the obese may pose challenges, like difficulties in proper patient positioning and landmark identification. However, Ultrasound guidance may help overcome many difficulties in regional techniques. But as expected, targets are more deeply situated in obese patients and the ultrasound beams are attenuated as they travel a greater distance through tissue layers. Additionally, when crossing a tissue boundary, a portion is reflected back to the transducer creating artifacts like speckling and clutter which are particular problems in the obese patient. [15] Few studies examined the use of ESPB in bariatric surgery [3,6,7], all indicating potential benefits of the technique in terms of opioid sparing and pain control. To date, the efficacy of ESPB has not been examined in superobese patient. So we aim to compare the perioperative analgesic effect of bilateral ultrasound-guided ESPB with controls, Local bupivacaine infiltration to the trocar sites, in super obese patients undergoing bariatric surgery We hypothesis that ESBP provides good applicable modality of perioperative analgesia for superobese patients undergoing bariatric surgeries.
The main purpose of this study is to determine if combining tirzepatide with the mibavademab will result in more weight loss in adult participants than tirzepatide alone. The study will last about 72 weeks and may include up to 19 visits.
The increase in childhood obesity is a multifactorial phenomenon influenced by dietary patterns, commercial factors, and social determinants; it has long-term consequences for both individual health and society as a whole. Despite recommendations for maintaining good health throughout life and promoting the Mediterranean Diet, due to the increased availability of ultra-processed and more appealing foods, children and adolescents are shifting towards a "Western" diet. One in four children consumes sugary and carbonated drinks every day, which contributes to a high intake of fructose in the diet, while fruits and vegetables are consumed less, and legumes are included in the diet of only 38% of children less than once a week. Fructose is a monosaccharide naturally found in fruits, vegetables, and honey; due to its high sweetness and taste-enhancing properties, fructose is widely used in the food industry. High-fructose corn syrup, in particular, is one of the most widely used ingredients in the production of soft drinks, jams, breakfast cereals, and bakery products. Non-alcoholic fatty liver disease (NAFLD), now also called metabolic dysfunction-associated fatty liver disease (MAFLD), is considered the hepatic manifestation of metabolic syndrome and currently represents the most common chronic liver disease in pediatric age in Western countries. Recent studies suggest that fructose consumption is implicated in the development of NAFLD both directly by providing metabolites that can be used for triglyceride and free fatty acid synthesis, and indirectly through increased uric acid production. High-fructose foods also appear to be a risk factor for bone loss. Numerous studies conducted over the past 25 years, during which fructose consumption has exponentially increased, have shown that this sweetener tends to increase the incidence of fractures and osteoarthritis and decrease bone mineral density (BMD) and new bone tissue deposition. The objective of this study is to understand the effect of fructose on the molecular events that contribute to the evolution of the pediatric age, and its effective relationship with the onset of liver and osteoarticular complications in this population. Understanding the mechanisms of fructose regulation and its effects on the body could be an important target to address the clinical and social problems arising from its spread in children.
This is a cohort study to understand the role of the human metagenome, and associated metabolites, in health and in various diseased states, in particular obesity as well as sarcopenia. Recruited participants will have their fecal, salivary, urine, serum, and in certain instances, mucosal samples taken, for metagenomic sequencing and metabolite testing. We hope to uncover various differences and signatures in the metagenome and metabolome in various diseased states, with potential future therapeutic applications in personalised medicine.

Sarcopenic obesity, characterised by concurrent reduced muscle mass and excess body fat, affects 11% of older adults worldwide, rising to 23% in those over 75. Considering the negative synergistic impact on health, promoting muscle mass gains while reducing fat mass remains a significant challenge, necessitating urgent and effective intervention strategies for managing SO. Exercise and nutrition are the primary interventions recommended for SO. This project aims to evaluate the effects of the EatWellLog App developed by the investigators' team for local older adults, in improving: - their sarcopenic obesity status, measured by all four diagnostic criteria, including grip strength, muscle mass, physical performance and body fat mass (primary outcome), and, - nutritional self-efficacy, nutritional status, dietary quality, health-related quality of life, and adherence to diet and exercise regimens (secondary outcomes), by enhancing the self-management abilities and longer-term adherence to daily diet management among participants in the M-health group using the App, compared to the control group. The EatWellLog App, designed for older adults with SO, incorporating Klasnja and Pratt's five-strategy framework for mobile health (mHealth) applications development to facilitate health behavioural change. This App supports users with SO in managing daily diets that promote gradual weight loss and muscle mass preservation, adhering to the dietary regimen for this population. Forty older adults with SO will be recruited from local community health centres and then randomized to either m-health or control groups. Both groups will receive an 8-week supervised programme separately. The programme consists of personalised dietary modification programme and group-based exercise training which have been tested and used in the investigators' pilot and General Research Fund (GRF) project. Additionally, only the m-health group will be instructed to use the App for daily diet self-management. Participants will be assessed on a variety of outcomes immediately after the 8-week supervised programme (T1), which will be compared to the baseline (T0). To explore the possible long-term effects of the intervention, other measurements will be conducted at 3-(T2) and 6-(T3) months after the supervised programme, which will be compared with those conducted at T0.
