Advances in patient selection, organ procurement and preservation, surgical technique, immunosuppression, and infection prevention have conferred significant decrease in rejection, infection, and subsequently improve cause-specific graft failure rates after kidney transplantation (KT). However, cardiovascular diseases (CVD) remained the main burden impairing both short-and long-term survival. Compared with the general population, conventional CVD risk factors, including obesity, liver and muscle insulin resistance, dyslipidemia, hypertension, and diabetes mellitus, are all highly prevalent in this population. Risk factors of these metabolic disorders are generally reported, including common risk factors and those specifically for kidney transplants, including long-term exposure to steroids and calcineurin inhibitors. Previous studies demonstrated that adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) is a central regulator of multiple metabolic pathways and a key player in regulating cellular energy metabolism. Activation of AMPK by pharmacological agents may hold a considerable potential to reverse the metabolic abnormalities in chronic metabolic diseases. Metformin, a widely used antidiabetic drug, have been reported to act as an AMPK activator by inhibiting complex I of the mitochondrial electron transport chain in many tissues, including adipose, skeletal muscle, and heart. A recent small clinical trial observed that metformin administration did improve some of the metabolic profiles for glucocorticoid-treated patients with inflammatory disease but without pre-existing diabetes. In addition, another antidiabetic drug sodium-glucose-cotransporter-2 (SGLT-2) inhibitors can improve metabolic parameters and cardiovascular risk in patients with or without diabetes in preclinical and clinical studies. A small clinical trial reported that compared to metformin, significant improvement in anthropometric parameters and body composition, in overweight and obese women with polycystic ovary syndrome after 12 weeks of treatment with empagliflozin. Hence, metformin and SGLT2 agents may be used as potential adjuvant therapies to improve metabolic disorders after KT. However, both metformin and SGLT-2 inhibitors were not recommended in patients with impaired kidney function considering their elimination and action mechanism. Although several preliminary clinical trials showed that metformin and SGLT-2 inhibitors can be used safely and improve glucose control after KT, but they are small-sample sized and only include patients with diabetes. We will conduct a prospective clinical trial with the first aim of exploring the safety of metformin and SGLT-2 inhibitors in kidney transplant recipients with or without diabetes, and the second aim of exploring their roles in improving metabolic profiling.
Raised plasma Homocysteine (Hcy) was 1st proposed as a cause of vascular pathology in patients with inherited disorders of Homocysteine metabolism.leading to the hypothesis that individuals with slight to moderate elevated levels of Homocysteine may have an increased hazard for vascular disease. As an amino acid with a reactive sulfhydryl group, homocysteine has been proposed to intermediate vascular inflammation and damage by stimulating oxidative stress secondary to reactive oxygen species accumulation. which in turn leads to an rise in cardiac and vascular disease risk by stimulating endothelial dysfunction, smooth muscle cell proliferation, and vascular calcification. Consistent with this hypothesis, hyperhomocysteinemia a has been associated with an increased risk for coronary heart disease (CHD), heart failure, atrial fibrillation, stroke, and mortality.
Background: In the U.S., about 53 million informal, unpaid caregivers provide care to a person who is ill, is disabled, or has age-related loss of function. These caregivers may be adult children, spouses, parents, or others. The stress of providing long-term care affects caregivers health and well-being. Researchers want to learn more about this stress and its effects. Objective: To learn how the caregiving process affects the health and well-being of caregivers over time. Eligibility: Adults aged 18 years and older who are caregivers for a person with a chronic medical condition and who have already given consent to take part in other study activities. Design: Participants will be put in different groups. They will complete some or all of the following tasks over 1 year. They may repeat these tasks once a year for up to 5 years. Participants will fill out 2 online surveys. One will ask about their health and their caregiving experience. The other will ask them to list people in their social network and their care recipient s social network who give them support. Participants will have a 2-part phone interview. It will be audio recorded. In part 1, they will be asked about the people they listed in the survey. In part 2, they will be asked about their caregiving experience and events in the care recipient s life. Participants may fill out a weeklong diary every 3 months. It will ask about their daily social activities, well-being, and stress levels. It will also ask about their thoughts and feelings about caregiving. Participants may give a blood sample each year they are in the study. ...
The aim of our study is to understand the biological pathways involved in the occurrence of IDy in patients with HF since ID is very common and supposes a negative impact in terms of clinical outcomes in these patients. In this context, a deeper understanding of the mechanisms involved in the development of ID in these patients and the impact on the altered biological pathways after iron replenishment will pave the way for an improvement and simplification of the preventive strategies in patients with HF.
The aim of this study is to report and describe cardiac manifestations associated with IMD in a cohort of patients followed in a reference center for rare diseases (Lausanne University Hospital, CHUV) from 2017-2020.
Numerous studies have established the role of nutrition on obesity and its related metabolic diseases, which together affect a billion individuals worldwide. Evidence indicate that meal timing regulates numerous metabolic processes suggesting that meal time manipulation may be a simple intervention against obesity and its metabolic diseases. Time-restricted eating (TRE) is a dietary manipulation that involves restricting food intake to 6-10 h/day with no energy intake the rest of the day. In rodents, TRE significantly decreases hepatic steatosis and dyslipidemia, while it supports a healthier hepatic cellular content even without caloric restriction, potentially by alternating activation of nutrient sensing mechanisms and effects on circadian oscillations. However, an understanding of the effect of TRE on liver health in people is not clear. Accordingly, we will conduct a randomized controlled trial in people with overweight/obesity and hepatic steatosis to determine the effect of 9 h TRE for 12 weeks, on key metabolic outcomes in liver health: 1) intrahepatic triglyceride content using magnetic resonance imaging; 2) de novo lipogenesis during fasting and postprandial conditions using administration of deuterated water in conjunction with mathematical modeling. The proposed study will enable us to determine the effect of meal timing on metabolic function in people with NAFLD.
The aim of the study is to evaluate modifications in the metabolism of polyunsaturated fatty acids (PUFA) and biosynthesis of the lipid mediators N-acylethanolamines (NAE), both known to induce and be induced by the nuclear peroxisome proliferator-activated receptor (PPAR)-α, which may also explain the well-established improved lipid and energy metabolism after bariatric surgery. The study is focused on understanding the weight loss mechanisms in order to develop targeted dietary protocols.
In order to obtain suitable exercise intervention model for children and adolescents with obese or metabolic syndrome in China, we conduct a RCT to examine the effects of different intensity exercise intervention on weight, and other cardiometabolic risk factors among children and adolescents, we also test the effects of exercise interventions on multi-omics such as metabolomics, gut microbiome, genetics, and explore the potential mechanisms by which exercise interventions modulate cardiometabolic risk. This is a randomized controlled study. Children and adolescents with obesity or metabolic syndrome were randomly divided into three groups, including low intensity exercise training group, moderate and intermittent high intensity exercise training group. The investigators will obtain organ hydrodynamics indexes by abdominal ultrasound and computational fluid dynamics technology, and obtain the metabolic regulation mechanism of the body in response to exercise through the detection of metabolism related small molecules in blood and urine and the analysis of intestinal flora, so as to explore the potential value and mechanism of different exercise modes in the treatment of obesity and metabolic syndrome. At the same time, the behavior and self-consciousness of children and adolescents will be investigated to obtain the suitable exercise intervention model for Chinese children and adolescents with obesity and metabolic syndrome. In conclusion, this study aims to demonstrate which exercise mode can alleviate obesity or reverse metabolic diseases, analyze which factors can sense exercise, and explore the potential mechanisms through mutil-omic approach, so as to improve metabolic syndrome.
