Filter by:This study investigates the potential of vericiguat, a soluble guanylate cyclase stimulator, to improve cardiometabolic health in obese Black individuals with insulin resistance by directly enhancing cyclic guanosine monophosphate (cGMP) activity. Given that this population has been shown to have lower cGMP activity and the association of lower cGMP activity with increased cardiometabolic disease risk, the proposed study hypothesizes that augmenting cGMP activity in obese individuals will improve insulin sensitivity and energy expenditure. This study is a placebo-controlled randomized trial involving 200 Black obese participants with insulin resistance, assessing the effects of vericiguat on insulin sensitivity, resting, and exercise-induced energy expenditure over 12 weeks. Additionally, it will explore changes in brown adipose tissue and gene expression related to energy metabolism in white adipose tissue, aiming to provide insights into how increasing cGMP activity may improve cardiometabolic health in Black obese individuals.
The study aims to evaluate the impact of different dietary interventions on abdominal fat components and cardiometabolic parameters. This is a randomized clinical trial study conducted in overweight adults, selected by voluntary adherence, in an outpatient clinic of a cardiology hospital. The sample was calculated based on data from a study with the Brazilian population, with the sample size calculated as a function of a mean difference (d) in visceral adipose tissue (VAT) after the interventions, standard deviation (s) and a significance level of 5% (z). To correct eventual losses, the number was increased by 20%. Four dietary interventions will be applied in the 6-month period: group with calorie restriction and balanced distribution of macronutrients (group 1); group with calorie restriction and low-carbohydrate diet (group 2); group with calorie restriction and low-fat diet (group 3) and group with collective nutritional guidance (group 4). Patients will be followed up monthly to assess weight loss, analyze adherence to the diet therapy plan, reinforce nutritional guidelines and monitor anthropometric measurements and abdominal adipose tissue. The evaluation of VAT and subcutaneous adipose tissue (SAT) by ultrasonography will be performed at baseline and after 6 months of intervention. The present study is expected to clarify the effects that different dietary interventions produce over 6 months on abdominal fat deposits and cardiometabolic parameters.
The purpose of this study is to investigate the physical and mental health status of middle-aged and elderly people of different ages and practicing Tai chi for different periods of time, so as to provide a strong theoretical basis and practical guidance for delaying age-related aging and preventing and treating the occurrence and development of chronic diseases.
Fitness is one of the best predictors for heart and brain disease. To increase ones fitness, the American Heart Association (AHA) says to exercise at least 150 minutes per week or 75 minutes per week if really hard. These exercise guides are pretty effective, however not everyone will get the same results. What individuals do outside of the exercise bout can influence the effectiveness of exercise. One of these factors is our time sitting, which has caused the phrase "sitting is the new smoking". Other studies have said that the metabolic benefits of exercise are decreased when you exercise after a few days of low activity (less than 5,000 steps per day). This is important in that exercise may not be able to fully offset these times of inactivity. However, these studies were only looking at different fats in the blood. As exercise increases fat burn up to 10 times in the muscle, more research is needed to understand how inactivity affects the muscle during exercise and after exercise. This study will help answer two questions: 1) How does a day of sitting a lot affect the muscle's ability to respond to exercise? and 2) How does a day of sitting a lot affect carbohydrate and fat burn during and after a bout of exercise? The investigators will answer these questions by having people complete one day of inactivity (less than 5,000 steps) or normal activity (more than 8,500 steps). Subjects will then come in the next day to bike somewhat hard for 1 hour. The investigators will take blood samples before, during, and after exercise to measure energy sources. The investigators will also collect pieces of skeletal muscle before and after exercise to see how the muscle responded to exercise. This study is significant for the publication of exercise guidelines to minimize risk of heart and metabolic diseases.
The Investigators propose suture plication placement at the distal gastric body drives a significant portion of weight loss in endoscopic sleeve and sutures only need to be placed in the distal gastric body. Therefore, in this pilot study, the investigators aim to compare "belt" with "belt and suspenders" plication pattern using the Endomina system to determine percent total weight loss.
The purpose of this prospective, observational study is to evaluate the tolerability and acceptability of Zero minis, a range of protein substitute tablets for use in the dietary management of children with either TYROSINAEMIA Type I, II, III or ALKAPTONURIA, HOMOCYSTINURIA, or MAPLE SYRUP URINE DISEASE (MSUD) over the age of 7 years.
The goal of this clinical trial is to clarify (i) the contribution of brain insulin action on regulation of systemic metabolism, (ii) sex-specific differences in the central regulation and (iii) the influence of the menstrual cycle in women. Therefore, participants will undergo oral glucose tolerance tests combined with a double tracer dilution technique. This approach will be compared between days with insulin delivery to the brain as nasal spray and days with placebo spray.
The aims of this collaborative, interdisciplinary research project are to understand and describe the psychological impact of the announcement of a rare, serious disease present since birth and detected in the context of the systematic neonatal screening (DNS), in terms of the parents' experience, but also on the part of the medical team, in order to improve its process and the support it provides for the announcement of the diagnosis.
The goal of this observational prospective project is to study the metabolic alterations during normal and complicated pregnancies, obtaining an early detection of metabolic changes, offering new insights into future prevention and treatment strategies for both mother and offspring. Primary objectives: - measurement of maternal blood adipokine levels, during the first trimester of pregnancy, in two groups of women (high and low risk), in order to identify early markers which, in conjunction with the medical history, can identify women at increased risk of developing GDM - ultrasound measurement of adipose tissue deposits at ectopic sites, comparing low- and high-risk women, and assessing the effect of pregnancy on these deposits. - Identification, by targeted ultrasound assessment, of fetuses at increased risk of macrosomia. Secondary objectives: - Evaluation of the prevalence of GDM and its complications in a population of low- and high-risk women. - Evaluation of neonatal complications in children born to low- and high-risk mothers (need for resuscitation, hypoglycaemia, hypocalcaemia, admission to neonatal intensive care unit). The participants will be recruited during first trimester ultrasound after signing the informed consent.
The goal of this retrospective/observational study is to compare the clinical outcomes between the high-cumulative-dose group and the low- cumulative-dose group of oral/inhaled corticosteroid in the long-term management of asthma patients. The main hypothesis are: i. High cumulative dose of corticosteroid is related to the prevalence of osteoporosis/osteoporosis in the long-term management of adult asthma. ii. High cumulative dose of corticosteroid can affect populations that have a high-risk of osteoporosis (females over 50 years of age). iii. High cumulative dose of corticosteroid is related to the prevalence of diabetes mellitus, hypertension, and hyperlipidemia in the long-term management of adult asthma. iv. High cumulative dose of corticosteroid affects bone metabolism-related diagnostic tests and laboratory values and the prescription rate of bone metabolism-related medications.
