Filter by:Metabolic disorders that can occur during pregnancy, in particular disorders of lipid metabolism and insulin resistance, can have a detrimental effect on pregnancy and the fetus. The triglyceride level and other lipids increase slightly during pregnancy. This increase has a positive effect on the development of the fetus. However, an excessive increase in lipid levels can cause some metabolic disorders such as gestational diabetes and increase feto-maternal morbidity/mortality. While some existing studies have shown that elevated triglyceride levels can cause fetal macrosomia, others have found no correlation between these two variables. The ratio of triglycerides to HDL is a widely used marker for lipid disorders. In addition, the triglyceride-glucose index is also an index used to detect insulin resistance.
The goal of this single-group, open-label, phase I/II clinical trial is to evaluate the safety and efficacy of the transplantation of umbilical cord mesenchymal stem cells in aging-related low-grade inflammation patients' pro-inflammatory cytokines. The main questions to answer are: - Is the transplantation of umbilical cord mesenchymal stem cells in aging-related low-grade inflammation patients safe? - Comparison of the expression levels of pro-inflammatory cytokines (IL-1α/β, TNF-α/β, IL-6, IL-11, IL-18, IFN-γ) in the patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Comparison of the expression levels of anti-inflammatory cytokines (IL-10, TGFβ, IL-1) in the patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Comparison of the inflammation balance by the ratios of pro-inflammatory cytokines to anti-inflammatory cytokines in the patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Comparison of the HbA1C index in the diabetes patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Comparision of the indices of Cholesterol, Triglyceride, LDLc, HDLc in the dislipidemia patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Comparison of the BMI in the obese patient's blood before (day 0), after 90 days, and after 180 days of cell transplantation. - Determination of adverse effect frequency in the patients before (day 0), during, after 90 days, and after 180 days of cell transplatation. Participants will receive two intravenous infusions of 100 million umbilical cord mesenchymal stem cells on days 0 and 90. The patient will be monitored for safety and measured as per the study protocol until day 180.
The goal of this clinical trial is to explore the role of wheat and corn germ blended oils in regulating oxidative stress and immunomodulation in dyslipidaemic populations, to explore their effects on intestinal flora, antioxidant and immunomodulation. The main questions it aims to answer are: - How does phytosterol-rich wheat corn germ blended oil affect oxidative stress and immune function in dyslipidaemic people compared to peanut oil? - How does phytosterol-rich wheat corn germ blended oil affect serum metabolites, serum fatty acid profile, and intestinal flora in dyslipidaemic populations compared to peanut oil? What are the specific mechanisms involved? Participants will be randomly assigned to the intervention and control groups, the packaging of germ oil and peanut oil will have a uniform appearance, and participants will be instructed to replace their household cooking oils with the distributed cooking oil for three months, in addition to replacing all the canteens in the staff units with the trial oil for more than three months. Participants did not know who was the control oil, germ oil or peanut oil, and both were randomly distributed to different groups of participants by the third-party supervisors. Researchers will compare peanut oil to see if phytosterol-rich germ oil can improve oxidative stress and immune function in dyslipidaemic populations, in addition to exploring possible underlying mechanisms of improvement using multi-omics techniques.
The breath analysis (BreathSpec® device) data of all participants that were included into the VAARA study (NCT05771090) will be analysed, this includes data from up to 40 breath samples from each of the 10 participants who underwent 2 insulin-induced hypoglycaemic episodes during two visits. The primary objective is to find a possible association between volatile organic compounds (VOCs) measured by the BreathSpec® device and blood glucose. For this we will use descriptive statistics, correlation coefficients, as well as a Principal Component Analysis and a partial least squares discriminant analysis. Furthermore, the time lag between hypoglycaemia onset and change in VOCs will be quantified.
In HIV-infected people with metabolic fatty liver disease and liver fibrosis of any degree, as measured by non-invasive testing, antiretroviral treatment that includes rilpivinire for 18 months results in a slowing of progression and/or reduction of fatty metabolic liver disease, attenuating inflammation and liver fibrosis.
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.
Epidemiological evidence is accumulating that a high consumption of added sugars is associated with metabolic diseases such as non-alcoholic fatty liver disease and type 2 diabetes. Fructose, one of the principal added sugars, is believed to be the most disadvantageous sugar. Data from a large population-based cohort demonstrated that fructose intake from fruit juice and sugar-sweetened beverages, but not whole fruits, is associated with higher intrahepatic lipid content. A study in mice demonstrated that fast fructose exposure resulted in higher intrahepatic lipid content than slow fructose exposure. The food matrix, i.e. the complex spatial organisation of and interactions between nutrients, may account for the fast versus slow fructose exposure and subsequent health consequences. Therefore the investigators aim to investigate the role of the fructose matrices on serum fructose peaks. The investigators hypothesize that liquid fructose matrices will cause higher serum fructose peaks in comparison to solid fructose matrices. Objective: To quantify serum fructose peaks within 150 minutes following intake of fructose-containing matrices.
The goal of this factorial randomized controlled trial is to find out whether time-restricted eating and flexitarian diet (on its own and combined) can improve cardiometabolic health markers in normal weight, young men with metabolic abnormalities? Participants will be assigned to four groups: control, flexitarian, time-restricted eating and time-restricted eating + flexitarian. Investigators will look for men with elevated fasting blood glucose or blood lipids level or blood pressure and with normal body weight and waistline. Participants from the flexitarian group will be asked to follow a diet that has been carefully designed for them by the PI and dietitian for the period of 8 weeks. Participants from the control group will receive general healthy eating recommendations. We aim to investigate if the experiment had any effect on changes in metabolic, inflammation and nutritional markers, blood pressure and body weight and composition. Also, the effect of diets on men's sleep, general wellbeing and satisfaction with treatment will be investigated. The proposed study can test a potentially effective nutritional intervention which is feasible to adopt and sustainable (in line with recent planetary diet recommendations). Confirming its effectiveness can fill the research gap, providing new knowledge and approach to the prevention and treatment of metabolic abnormalities in young, lean men.
Obesity and glucose intolerance or overt diabetes are increasing at an alarming rate in the population, and are bound to become a public health issue and a major cause of disability, loss of independence and high social costs in the near future. A large body of evidence has in recent years highlighted, among the negative effects of overnutrition and glucose dysmetabolism, also an acceleration of cognitive decline and of brain senescence, through cellular (vascular, neuronal, or both) and molecular mechanisms still incompletely clarified. Understanding how overweight and impaired glucose homeostasis negatively affect brain function represents both a major scientific challenge and an avenue to early detection and possibly prevention of this invalidating complication. The aim of this project is to obtain neuronal progenitor-like cells from skin fibroblasts in order to correlate patient-specific metabolism to adult neural stem cell (NSC) and neuronal function in vitro.
Dietary interventions have been consistently proposed as a part of a comprehensive strategy to lower the incidence and severity of atherosclerosis and cardiovascular diseases (CVD). Excessive consumption of fats enriched in saturated fatty acids (SFA) is associated with an increased risk of atherosclerosis and other CVD. By contrast, replacement of SFA with monounsaturated fatty acids (MUFA) and omega-3 long-chain polyunsaturated fatty acids (ω-3 PUFA) has been reported to be inversely associated with risk of atherosclerosis. This is partly due to the ability of MUFA (and PUFA) in modulating low-density lipoprotein (LDL) and triglyceride-rich lipoprotein (TRL) lipid composition and oxidation status, and thereby the functionality of such lipoproteins. While most of the nutritional studies have focused on elucidating the mechanisms by which dietary fats affect LDL and TRL, little or nothing is known about the regulatory effect of MUFA and PUFA on structure and functional remodelling of high-density lipoproteins (HDL). There is clear evidence of an inverse association between plasma levels of HDL and the formation of atherosclerotic plaques. However, recent studies have suggested that HDL may not be as beneficial as thought at least in patients with established cardiometabolic disorders. In those patients, the HDL behaves as pro-inflammatory lipoproteins. Until now, few studies have addressed this "dark side" of HDL and has never been evaluated the role of dietary fatty acids on HDL plasticity (i.e. phenotype and functionality). A better understanding of this duality between anti-inflammatory and pro-inflammatory HDL would be relevant to prevent HDL-related atherogenic dyslipidemias and to provide personalized dietary advices for a successful management of atherogenic lipid profiles. This step of proof-of-principle will determine the instrumental role of major fatty acids present on a diet (SFA, MUFA and MUFA plus ω-3 PUFA) in promoting or reversing the phenotype of pro-inflammatory HDL. We expect to offer a novel insight on HDL and its relationship with dietary fatty acids through the following objectives: 1) To analyse acute changes in the lipidome, proteome and functional properties of HDL in humans (healthy volunteers and patients with metabolic syndrome) upon a challenge of a meal rich in SFA, MUFA or MUFA plus ω-3 PUFA; and 2) To analyse the influence of diets rich in SFA, MUFA and MUFA plus ω-3 PUFA on HDL plasticity in a preclinical animal model of diet-induced metabolic syndrome and that develops atherosclerosis.
