NCT07255300
A large ongoing randomized, open-label trial aimed at evaluating the effects of two different dietary interventions, FMD and LD, on body composition and cardiovascular (CV) biomarkers in a real word population (NCT05698654) is actually ongoing. This trial started in January 2024 will enrol 501 adult subjects between the ages of 30 and 65: 167 subjects randomized to the FMD arm with a 5-day meal program once every three months for a 6-month period (arm 1); 167 subjects randomized to follow the FMD plus a Longevity Diet program (FMD+LD) for a 6-month period (arm 2); 167 randomized to the control group (arm 3) that will continue their usual diet. On 2024,410, participants were enrolled and randomly assigned to FMD, FMD + LD, or control arm. Although preliminary data demonstrated the beneficial effects of such nutritional plans on body weight, BMI, body composition, and cardiovascular (CV) biomarkers, limited data is available on the long-term effects of these powerful nutritional interventions.

NCT06987240
A comparison of two different methods used in routine anesthesia practices will be made for the insertion of a catheter that will be placed at the waist for anesthesia in obese patients who will undergo orthopedic surgery. 60 obese patients aged 40-80, ASA II-III, BMI\>30, who are planned to undergo elective orthopedic lower extremity surgery by placing a combined spinal epidural catheter at Sakarya University Medical Faculty Education and Research Hospital will be included in the study. General anesthesia or regional anesthesia techniques are routinely used in lower extremity surgery in our clinic. When placing a combined spinal epidural catheter, the entry site is determined by looking at anatomical landmarks or using ultrasound. Patients will be divided into two different groups as Anatomical Marking or Ultrasound. Patients in the Ultrasound group will be taken to the block room in our operating room before the operation and a location marking will be performed with Ultrasound in the block room. Patients in the Anatomical Marking group will be brought to a sitting position in the operating room in the operating room and a location marking will be performed by hand examination. After determining the needle entry site, patients in both groups will undergo the Combined spinal epidural catheter placement procedure, which is performed routinely under sterile conditions, and the success rate at the first attempt, total success rates, number of needle redirections, and complications during the procedure will be compared.
NCT03146156
Studies evaluating lifestyle intervention in obese women during pregnancy have reported limited success in decreasing excessive gestational weight gain, and have failed to achieve the key outcome of breaking the obesity cycle and reducing neonatal adiposity or birth weight. Although some investigators advocate weight loss during pregnancy in obese women, these recommendations were based on extrapolation of retrospective epidemiological data. Of concern, we reported increased small for gestational age babies and decreased lean body mass in neonates of obese women with weight loss or inadequate gestational weight gain. Based on our research, optimal outcomes from lifestyle interventions are likely to be temporal and therefore must be initiated prior to conception to first improve maternal metabolic function, and subsequently, placental/fetal growth. Several large retrospective cohort studies support our hypothesis. For example, women who lost weight between pregnancies had fewer large for gestational age babies in contrast to women who increased interpregnancy weight. In addition, prospective randomized controlled trials have shown that postpartum weight loss is achievable without adverse maternal or neonatal outcomes, these studies include women who breastfed. Based on these observations, we propose a randomized control trial to determine the effect of lifestyle intervention initiated prior to a planned pregnancy on improving neonatal metabolism and adiposity. Our overarching hypothesis is that the maternal pre-pregnancy metabolic condition determines the obesogenic in-utero environment, which affects programming of placental mitochondrial function and metabolic pathways, promoting lipid accumulation and neonatal adiposity. Our rationale is based on the need to establish the most effective time to introduce an intervention that will break the obesity cycle in mothers and their children. Understanding how pregravid metabolic conditioning improves maternal physiology, and cellular and molecular function in pregnancy will provide the empirical data to support the intervention. We have a highly successful record of recruiting women who are planning a pregnancy, obtaining compliance in longitudinal studies, and in long-term follow-up of mothers and their offspring. Lifestyle intervention will be initiated prior to conception to decrease maternal body fat, inflammation, insulin resistance, and ?-cell dysfunction. Our transdisciplinary team has the required expertise in lifestyle interventions management of obesity, and in human physiology that is needed to determine the effects of these interventions on maternal metabolism and fetalplacental growth and function. We will recruit 200 women to pursue the following specific aims: Specific Aim 1: To investigate the physiological significance of lifestyle intervention in preparation for pregnancy (LIPP) on maternal and neonatal metabolism and adiposity. Specific Aim 2: To determine the molecular effects whereby lifestyle intervention initiated before pregnancy can improve placental mitochondrial lipid oxidation and accumulation.
NCT06911346
This single-blind, randomized controlled trial aims to evaluate the effects of increased dietary polyphenol intake-either through a healthy plant-based diet (PBD) or supplementation-on body weight and cardiometabolic risk factors in adults with overweight or obesity. A total of 99 participants (aged 25-45 years, BMI 25-35 kg/m²) with cardiovascular risk factors will be recruited from local health centers and randomly assigned (1:1:1) to one of three intervention groups for 12 weeks: (1) a healthy PBD rich in polyphenols, with supplemental apple, blueberries, hazelnuts, extra-virgin olive oil, and coffee provided at no cost to the participant (2) a healthy diet plus polyphenol supplementation (≈30g/day) from maqui , green tea, olive leaf, cranberry, and grape extracts, or (3) a control group receiving placebo and standard healthy diet recommendations. All groups will follow a caloric deficit. Dietary intake will be assessed using three 24-hour dietary recalls at baseline and 12 weeks, with polyphenol intake estimated via the Phenol-Explorer database. Data collection will include lifestyle questionnaires, anthropometric and bioimpedance measurements, blood pressure assessments, physical activity monitoring via accelerometers, and strength evaluations. Blood samples will be analyzed using a large-scale targeted metabolomics approach (UHPLC-MS/MS) to identify metabolic signatures, particularly those linked to gut microbiota. Faecal samples will be collected at baseline and visit 3. Findings will provide insights into how dietary polyphenols-either from whole foods or supplementation-affect obesity-related outcomes and cardiometabolic risk, potentially unveiling gut microbial biomarkers as future therapeutic targets. This study aims to contribute to strategies for obesity and cardiometabolic risk prevention and treatment.
NCT07253155
Inflammatory bowel disease (IBD) affects over 6.8 million people worldwide, with current treatments often causing side effects and poor patient compliance. Dysbiosis of gut microbiota is a key factor, and while probiotics are considered safe and beneficial, conventional strains fail to function effectively during active inflammation due to high iron levels in the gut. Streptococcus thermophilus (FX856), unlike traditional probiotics, can thrive in this iron-rich environment, promoting mucosal healing. A 2-way crossover intervention study will be conducted with FX856 supplementation in overweight and obese individuals who often exhibit mild gut inflammation by measuring faecal calprotectin and systemic inflammatory markers.
NCT06935838
This is a prospective cohort study of 12 overweight (with one or more weight-related condition) or obese adults with well controlled HIV-1 on antiretroviral therapy (ART). An initial dose of tirzepatide (TZP) 2.5 mg subcutaneous (SQ) once weekly will be given, escalated by 2.5 mg at 4-week intervals to a final dose of 7.5mg. The investigators will collect the following information via review of the medical record: age, race/ethnicity, sex, medical conditions, medications, most recent standard of care HIV labs (including T-cell panel and HIV-1 viral load). The primary outcome will be the change in baseline body weight at 12 weeks. Secondary outcomes will be changes in body composition, liver fat content and liver stiffness, inflammatory markers, cardiometabolic markers (lipids and HbA1c), and monocytes at 12 weeks. There will be a 4-week safety follow up off TZP.

NCT06791837
Cerebral blood flow (CBF) is essential for maintaining brain health and function, as it ensures delivery oxygen and nutrients necessary to support neuronal activity. Reduced CBF can impair the brain's ability to meet its metabolic demands, leading to deficits in cognitive ability. Impairments in CBF are associated with cognitive decline and neurodegenerative disease such as Alzheimer's and dementia. Many factors influence CBF, but recently lactate has emerged as a key player. Blood glucose has long been considered the primary fuel for the brain, but emerging evidence indicates that lactate may be the preferred fuel for neurons, and lactate may become even more important under stressful conditions. Individuals with obesity often have impaired lactate metabolism resulting in higher resting blood lactate concentrations and reduced ability to clear lactate after a physiological stress. At the same time, it is known that exercise is a powerful intervention for improving lactate metabolism. Thus, this project seeks to investigate the role of lactate in brain blood flow in individuals with and without obesity as well as establish if short term exercise training (individuals with obesity only) will alter circulating lactate concentrations at rest and in response to exercise.
NCT07008352
This observational study aims to investigate the changes in serum amino acid metabolism before and after bariatric surgery in obese individuals. Blood samples will be collected from 50 patients at baseline (preoperative), and at 1 and 3 months postoperatively. An additional 50 healthy individuals will serve as the control group. Amino acid profiling will be conducted using LC-MS/MS. The study seeks to determine how bariatric surgery affects metabolic pathways associated with amino acid regulation.
NCT05940675
The GHK intervention was developed according to the United Kingdom Medical Research Council's framework for developing and evaluating complex interventions. A pilot- and feasibility study was conducted during December 2022-April 2023, and the intervention was subsequently adapted and adjusted. The GHK main trial is a two-school-year cluster-randomized school- and community trial designed to investigate the effect of the multi-setting, multi-component GHK intervention program on weight development, health and wellbeing in Danish children aged 6-11 years. The trial will include 24 schools in Denmark (12 intervention and 12 control). The primary aim of the cluster-randomized trial is to investigate whether the GHK intervention program can promote healthy body composition as measured by fat mass (FM) in the intervention group compared with the control group. We hypothesize that the intervention will result in less FM gain in the intervention group compared with the control group over the two school-year study period.
