Filter by:The objective of the study is to assess the effect of two diets with different fat composition on cholesterol metabolism. The study was a randomized cross-over trial where volunteers follow two study periods with different types of meat (lean and fat red meat) separately by a ten days wash-out period. At the beginning of the study and after the study periods the following parameters are determined: anthropometric (weight, waist, circumference and body mass index), blood pressure, dietary (72-hours dietary registry) and exercise assessments and biochemical analysis (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, iron, transferring, ferritin, uric acid, glucose, HbA1c and insulin). Serum concentration of non cholesterol sterols (sitosterol, campesterol, stigmasterol, desmosterol and lanosterol) and oxysterols (24S-hydroxycholesterol, 27-hydroxycholesterol and 7α-hydroxycholestenone) were measured by High Performance Liquid Chromatography tandem Mass Spectrometry in these subjects throughout along the study in order to demonstrate the effect of different red meat on the hepatic metabolism of cholesterol.
This study plans to learn more about immune responses in intestinal (gut) tissue in people with human immunodeficiency virus (HIV) infection. This study will determine whether change in the composition of gut bacteria in HIV infected individuals is related to a high prevalence of chronic gut inflammation and metabolic disease. The investigators will also investigate immune-modulatory properties of specific bacteria that correlate with disease both by characterizing which functional genes are selected for in their genomes and by stimulating immune cells isolated from blood and gut tissue with bacterial isolates. This work will establish whether gain/loss of bacterial drivers/suppressors of information in the gut contributes to metabolic disease in HIV-infected individuals.
The primary objective of the study is to determine the safety and feasibility of intrathecal administration of DUOC-01 as an adjunctive therapy in patients with inborn errors of metabolism who have evidence of early demyelinating disease in the central nervous system (CNS) who are undergoing standard treatment with unrelated umbilical cord blood transplantation (UCBT). The secondary objective of the study is to describe the efficacy of UCBT with intrathecal administration of DUOC-01 in these patients.
Rationale: Increased intakes of n-3 long chain polyunsaturated fatty acids eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA), mainly found in fatty fish, are recommended for the prevention of coronary heart disease. Alpha-linolenic acid (ALA, C18:3n-3) is the most common vegetable-oil based n-3 fatty acid. Evidence exists that ALA supplementation can also have a protective effect on the development on cardiovascular disease, but may exert its cardio protective effects through different routes. The benefit may (partly) be due to blood pressure lowering. However, evidence for beneficial effects of ALA on blood pressure is conflicting. Therefore, we propose to investigate the effect of flaxseed oil, high in ALA, using a study powered on 24-hour blood pressure, in a population with high normal blood pressure and mild hypertension. Objective: To study the effects of flaxseed oil, rich in ALA on 24h-ambulatory mean arterial pressure (MAP) in men and women with high-normal blood pressure and mild hypertension compared to high oleic sunflower oil, poor in ALA. Study design: Using a double blind randomized, placebo-controlled parallel design, subjects will receive at random daily 10 g of flaxseed oil or a high-oleic acid sunflower oil (HOSF) as control for twelve weeks, with a run-in period of 14 days in advance. Study population: 72 men and women, aged 40-70 years, with untreated high-normal blood pressure and stage I hypertension and a body mass index between 25 and 35 kg/m2 will participate in the run-in and intervention period. It is estimated that 144 subject have to be screened to find 72 subjects that will enter the run-in period. Intervention: During the run-in period, subjects will receive daily 10 g of palm super olein oil. During the intervention period subjects receive either 10 g of HOSF or flaxseed oil. All oils are provided in bottles of 5 g, one will be consumed at breakfast or lunch and one at dinner. Main study parameters/endpoints: The main study parameter is the change in 24h-ambulatory mean arterial pressure (MAP)
The purpose of this study is to compare the effect of lanthanum carbonate and calcium carbonate on the progression of coronary calcification and vascular endothelial dysfunction.
The purpose of this study is to determine a safe dose of BPX-501 gene modified T cells infused after a haplo-identical stem cell transplant to facilitate engraftment and the safety of Rimiducid (AP1903) on day 7 to prevent GVHD.
The purpose of this study is to determine whether cholecalciferol supplementation decrease the blood concentrations of hepcidin-25 in hemodialysis patients.
Many patients in the hospital who are malnourished or not eating received intravenous feeding or total parenteral nutrition (TPN). Despite improving nutrition, TPN may increase the risk of infections and hospital complications. We do not know why TPN increases hospital complications, but it may be caused by the high sugar or fat content in TPN solutions. The investigators believe that the high sugar and high fat content can limit the ability to fight infections and produce stiffness of blood vessels. This study will compare the effect of high sugar, high fat content or both on blood sugars, blood vessel function, on blood vessel function. The investigators will also compare the effect of different fats (olive oil and soybean) in the TPN solution on the risk of infection and blood vessel function on a total of 12 healthy subjects.
This single-institution, phase II study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) using busulfan- and fludarabine-based conditioning regimens with busulfan therapeutic drug monitoring (TDM) for patients with various inherited metabolic disorders (IMD) and severe osteopetrosis (OP).
Background: - Being overweight may cause low-level inflammation. This inflammation may cause some of the medical problems of obesity, like high blood sugar (diabetes) and heart disease. This study will test whether a medication called colchicine can improve metabolism in adults who are overweight but have not yet developed diabetes. Objectives: - To learn whether colchicine improves sugar regulation and metabolism. Eligibility: - Healthy overweight adults18 to 100 years old. Design: - Participants must fast before each visit, including the screening visit. - Participants will be screened with blood tests,urine tests, medical history, and physical exam. They will have to drink sugar water, and have blood drawn to find out if they are healthy. - For visit 1, participants will have a medical history and physical exam and answer questions. They will have blood taken with an intravenous (IV) line, give urine sample, and give 2 stool samples.. - Also, subjects will get sugar water through one IV. Blood will be drawn from the other. This measures sugar and insulin levels. During this, participants will lie in a bed and can watch TV. - Participants will have a full-body X-ray, lying on a table while a camera passes over them. They will also have an abdominal CT scan, lying on a table that moves through a ring that takes pictures. - Participants will have a small fat tissue sample taken from their abdomen. It is like getting a mini-liposuction. - Participants will be given the study drug or placebo. They will take it twice daily for 3 months. - For visit 2, participants will have blood tests, urine tests, medical history, and physical exam. - For visit 3, participants will repeat the tests in visit 1.
