Active clinical trials for "Metabolic Diseases"

This research application will explore the impact of the Non-nucleoside reverse transcriptase inhibitor (NNRTI) doravirine in the setting of established Nucleoside reverse transcriptase inhibitors (NRTIs) backbone [Tenofovir alafenamide (TAF) / Emtricitabine (FTC) as a possible therapeutic strategy to minimize the detrimental impact of ART-related toxicities on metabolism and instigators of atherosclerosis. Given the possible favorable role of NNRTI in pathogenesis of HIV-related dyslipidemia and cardiovascular disease (CVD), this research will provide mechanistic insights into HIV pathogenesis and safety data regarding doravirine (DOR). These data may promote DOR as a robust "HDL friendly" and "metabolism friendly", therapeutic agent that may attenuate morbidity in chronic treated HIV infection. Towards this aim, the investigators will study DOR-related effects on HDL (HDL-C levels and function) and ex vivo assays that determine key molecular determinants of atherogenesis.

Androgen excess is the cardinal biochemical feature of polycystic ovary syndrome (PCOS), a lifelong metabolic disorder affecting 10% of women. Serum testosterone correlates with insulin resistance in women, however, there is an urgent need to improve our understanding of the association between androgens and the risk of type 2 diabetes. Recently, a new subclass of androgenic steroids known as 11-oxygenated androgens has been identified. Utilising highly sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) techniques, our group has recently demonstrated that 11-oxygenated steroids are the predominant androgens in both health controls and women with PCOS, and that these correlate closely with markers of insulin resistance. The bioactive 11-oxygenated androgen 11-ketotestosterone (11KT) binds and activates the androgen receptor with equal affinity to testosterone, yet nothing is known about its impact on metabolism or glucose homeostasis. Intriguingly, unlike testosterone, 11-oxygenated androgens do not decline with age in women, and, therefore, may mediate an increased risk of T2DM in women across their life course. Therefore, this previously ignored androgen class is likely of major importance in female metabolic health, and may represent a novel metabolic risk factor and biomarker. However, 11-oxygenated androgens are not currently measured in routine clinical practice. To date, no population-based or human in vivo physiology studies have examined the association between 11-oxygenated androgens, glucose metabolism and diabetes risk in women, despite the high prevalence of PCOS in the female population. There is emerging evidence, even in women without a confirmed history of PCOS, that the levels of androgens over time correlate with their likelihood of developing metabolic and cardiovascular disease. This has not been studied to date in a prospective manner in healthy women in the background population using long term follow up data.

Background: Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates may not work well for all people. Researchers want to find more accurate ways to measure a person s metabolism. Objective: This natural history study will examine the relationships between metabolism, body composition, and body surface area in a wide range of people. Eligibility: Healthy children and adults aged 2 years or older. Also, people aged 2 years or older with conditions that may alter metabolism. These may include diabetes, obesity, renal disease, or cancer. Design: Participants will spend 2 days and 1 night in the hospital. They will provide a medical history and answer questions about their activity levels, the foods they eat, and their lifestyle. They will also eat a special diet. Participants will undergo many tests: They will lie in a bed with a clear hood covering their head for 30 to 45 minutes to measure the gases in their breath. They will lie on a padded table for about 15 minutes while their body is scanned. They will stand on a platform while a 3D scanner measures their body. They will have a test to measure how fast an electric signal moves through their body. They will grip an instrument to measure the strength of their hands. They will drink salty water and provide blood and urine samples. Participants may be invited to return for these 2-day visits up to 8 times per year. Return visits must be at least 2 weeks apart.

To collect lab data from capillary and venous blood specimens for use in analytical research studies to support the development and validation of laboratory procedures.

PräVaNet is a prospective, 1:1 randomized, controlled trial to investigate the efficacy of a new, digitalized prevention strategy ("ePrevention") in cardiovascular high-risk patients with type 2 diabetes mellitus in the outpatient sector.

Steroid injections are used for interventional pain management. However, their side-effect of immunosuppression may increase the risk of infections. Magnesium is an alternative anti-nociceptive injection that may be used instead of steroids. Prospective observational study of patients who received magnesium injection for interventional pain therapy, instead of steroid injection. Post-injection data collection includes numerical rating pain score, and sleep quality score. Pain is measured using the numeric pain rating scale. Sleep score is measured using the Likert sleep scale. A change in the pain or sleep scores by 2-points is considered significant.

SchizOMICS is a Phase IV, multicenter, dose-flexible, open-label, randomized controlled clinical trial to evaluate the efficacy and safety of aripiprazole versus paliperidone using multi-omics data in patients with a first psychotic episode. The trial will include a total of 244 patients, with two arms of treatment with paliperidone and aripiprazole (1:1). The main objectives of the study are: To compare the efficacy and safety of aripiprazole and paliperidone in the treatment of first episode psychosis (FEP) subjects in real-world clinical settings at 3 months. To elucidate whether non-responders after 3 months of adequate treatment may display different molecular signatures at baseline based on multi omics data and systems biology analysis. To uncover whether the appearance of side effects after 1 year of adequate treatment may be related to different molecular signatures based on multi-omics data and lifestyle phenotype using systems biology analysis.

The Physical Activity and Nutrition in Children (PANIC) Study is a single-centre controlled trial on the effects of a combined physical activity and dietary intervention on cardiometabolic risk factors and other health outcomes in a population sample of children from the city of Kuopio, Finland. The study provides novel scientific information for the identification of cardiometabolic diseases and other chronic diseases since fetal period and for the prevention of these chronic diseases since childhood. The main hypothesis of the PANIC study is that individuals at increased risk of cardiometabolic diseases and other chronic diseases can be identified in childhood and that it is possible to start the prevention of these chronic diseases by a long-term physical activity and dietary intervention since childhood.

The Nutrition Research Unit at Copenhagen University Hospital Herlev will during the fall 2013 initiate a randomized and controlled intervention study engaging 390 obese pregnant women. The overall aim of APPROACH is to investigate how an optimal diet during pregnancy influences the programming of the offspring. The children will after birth be included in a prospective cohort according to maternal randomization and examined six times from delivery until the age of nine years.

Consistent evidence suggests that mitochondrial dysfunction plays a crucial role in Parkinson¿s disease pathogenesis. Inhibition of complex I of the mitochondrial electron transport chain is sufficient to reproduce biochemical and pathological features of Parkinson¿s Disease in animal models (PD). Alterations of mitochondrial energy metabolism may intervene in PD pathogenesis by inducing inflammation, generation of reactive oxygen species (ROS), and neurodegeneration. The Nuclear factor erythroid 2-related factor 2 (Nrf2) is a regulator both of mitochondrial function and biogenesis, and of cellular resistance to oxidative stress, and may represent a novel target of PD disease-modifying therapies. The aims of the present study are to validate indicators of energy metabolism as biomarkers in PD patients and to evaluate the efficacy of drugs and natural food supplements acting on the Nrf2 pathway in improving motor impairment and Gait in PD patients.
