Filter by:The study conducted a health survey among Thai adults in 2022 and found a significant increase in obesity and nonalcoholic fatty liver disease (NAFLD), leading to metabolic-associated steatotic liver disease (MASLD). The prevalence of NAFLD was 19.7%, with higher rates in individuals with metabolic syndrome and diabetes. MASLD is associated with insulin resistance and genetic polymorphisms, particularly the patatin like phospholipase domain containing 3-rs738409 variant. Additionally, physical activity was inversely related to liver disease risk, with higher step counts associated with reduced incidence of NAFLD and liver-related mortality. The study aims to investigate the impact of dietary advice and pedometer use on physical activity levels and health outcomes in MASLD patients over 24 weeks.
Study Aim and Goals 1. Evaluate the correlation between genetic polymorphism and ROP development 2. To study the possibility if there are any specific genetic polymorphisms that lead to poor outcome or recurrence of ROP after treatment.
The purpose of this study is to investigate the relationship between the side effects(especially arthralgia and arthritis) which appear in the patients who are prescribed aromatase inhibitor(AI) and the CYP19 genetic polymorphisms.
This is a multicentric prospective cohort of all stage melanoma patients from AP-HP ,the largest consortium of University hospitals over Europe. 7 investigation sites (7 dermatological services of AP-HP) in Ile de France region are involved. 1300 patients will be enrolled and be followed during 10 years.
The purpose of this study is to determine whether polymorphisms in G protein subunits, namely Galphas and Galphaq, are associated with altered cardiac performance in heart failure patients.
We are going to investigate the association of multiple genetic polymorphisms with the metabolic side effects in patients with schizophrenia taking clozapine.
Age related macular degeneration (AMD) is a multifactorial disease with a strong genetic component. Most importantly a genetic polymorphism in the gene encoding for the complement factor H (CFH) has been recently identified which is highly associated with an increased risk of developing AMD. This Tyr402His polymorphism located on chromosome 1q31 has been implicated to play a role in the development of the disease. Given that it is known that impaired regulation of choroidal vascular tone is present in patients with AMD, the current study seeks to investigate whether the Tyr402His polymorphism is associated with altered choroidal autoregulation in healthy subjects. For this purpose a total of 100 healthy volunteers will be included in order to test the hypothesis that an impaired regulation of choroidal blood flow is present in subjects with homozygous Tyr402His variant.
Heme oxygenase 1 (HO-1) serves as a protective gene. It has been shown that one factor modulating HO-1 activity is a genetic variation in the HO-1 gene (functional GT length polymorphism in the promotor region). Heme arginate is a strong inducer of HO-1 as shown in several animal experimental studies. The aim of this clinical trial is to evaluate the HO-1 stimulation of heme arginate in healthy humans.
Background: Satraplatin is an experimental drug that may be of benefit to patients with prostate cancer. Prednisone is approved for treating prostate cancer. The gene excision repair cross-complementing rodent repair deficiency complementation group 1 (ERCC1) helps repair cell damage caused by satraplatin. It is possible that patients who have a variant of this gene will not benefit from treatment with satraplatin because the drug will not be able to damage the cancer cells effectively. Objectives: To determine if satraplatin may help treat prostate cancer in patients with certain variants of the ERCC1 gene. Eligibility: Patients with advanced androgen-independent prostate cancer whose disease has not responded to hormonal therapy or at least one type of chemotherapy and whose x-rays, scans or other tests have shown their cancer to be spreading. Design: Participants have a blood test to determine if they have a variant of the ERCC1 gene. Participants take satraplatin by mouth every day for 5 consecutive days out of every 35 days and prednisone by mouth every day. These 35-day treatment cycles may continue for 6 months or longer, depending on the benefits and side effects of the treatment. During the treatment period, patients undergo the following tests and procedures: - Blood tests on days 1 of the treatment cycle. - Weekly blood draws for the first 3 treatment cycles. - Imaging studies (e.g., bone scans, computed tomography (CT) scans) every two cycles to determine the response to treatment. - Surgical or medical suppression of testosterone in patients whose cancer cells continue to grow due to exposure to the hormone....
This study will begin to define these critical determinants for patients undergoing procedures in the hybrid interventional cardiology/cardiac surgery suite. In future studies, the data obtained from this study will be used to prospectively stratify patients in terms of bleeding verses thrombotic risk to design studies to optimize anticoagulation and anti-platelet therapies in the hybrid setting.
