Active clinical trials for "Metabolic Diseases"

Hyperphosphatemia is still an unresolved problem among hemodialysis patients and significantly increases the risk of death from cardiovascular diseases. Research to date has not answered the question of whether dialysate bicarbonate concentration profiling can improve phosphate removal and its concentration without negative impact on the acid-base balance. This study addressed this issue. Twenty stable hemodialysis patients will enroll to a four-week study during which different dialysate bicarbonate concentration profiles will be used each week. Each patient will undergo the following profiles (one-week periods): Treatment A - stable dialysate bicarbonate concentration Dbic 35 mmol/L during the whole HD session, Treatment B - Dbic 35 mmol/L for the first two hours and Dbic 30 mmol/L for the next two hours and Treatment C - the opposite mid-HD change Dbic from 30 to 35 mmol/L and one week wash-out period between Treatment B and C. We will collect blood samples each hour during the session and one hour after HD completion.

People who are obese often have insulin resistance (inability of insulin to properly control blood sugar) and high blood sugar. However, not all people with obesity have this problem. About one-third of people with obesity have normal sugar metabolism (the way your body uses sugar). Similarly, not all people who are lean are also metabolically healthy and a subset of people who are lean are referred to as metabolically abnormal lean (MAL) or metabolically obese lean because they have the abnormalities in glucose metabolism typically associated with obesity. The reasons why some people with obesity have a problem with blood sugar control and others do not are not entirely clear. It is thought that impaired muscle sugar uptake is the main problem related to high blood sugar in people with obesity. However, adipose tissue (fat tissue) also consumes a substantial amount of blood sugar. Therefore, it is unclear whether muscle or adipose tissue (fat tissue) are primarily responsible for altered blood sugar concentrations in persons with metabolically abnormal obesity (MAO) (those with insulin resistance), compared to those with metabolically normal (healthy) obesity (MNO), or whether "healthy" adipose tissue (fat tissue) expansion in MNO people compared with lean people provides a vessel for blood sugar removal that helps maintain normal blood sugar concentration. Accordingly, the investigators will determine the amount of sugar that is taken up by the body and in the cells of adipose tissue (fat tissue) and muscle by infusing labeled sugar into the blood and looking at its disappearance from blood and appearance in adipose tissue (fat tissue) and muscle. The investigators will also determine how well insulin, a hormone that controls blood sugar, turns on signals that stimulate sugar uptake in fat and muscle cells. These studies will be done after an overnight fast and during an infusion of sugar and insulin (hyperinsulinemic-euglycemic clamp), in sex- and age-matched people who are insulin resistant and insulin sensitive. People with obesity will also be invited to complete a ~10% diet-induced weight loss program and will be studied again after they have achieved the weight loss goal. A group of sex- and age-matched metabolically normal lean participants will serve as control group. An attempt will be made to also study a group of sex- and age-matched metabolically abnormal lean participants.

The objective of this study is to compare laboratory tests profiles of a botanic drug XueZhiKang (XZK) 300 mg capsules versus a marketed drug Lovastatin 20 mg tablets in healthy male volunteers between 18 and 50 years of age.

This is an open-label, non-randomized crossover design feasibility trial comparing oral hydrocortisone treatment with interval bolus delivery (pulsatile) of subcutaneous hydrocortisone via infusion pump in children with congenital adrenal hyperplasia. Eight children, ages 4-18 yrs, will have 24-hr pharmacokinetic and pharmacodynamic profiles of cortisol, 17-hydroxyprogesterone and androstenedione concentrations while on oral hydrocortisone therapy (admission 1), during an initial trial of the subcutaneous hydrocortisone pump (admission 2), and after 6 weeks of subcutaneous hydrocortisone pump treatment (admission 3). An integrated pharmacokinetic and pharmacodynamic model will be used to determine cortisol, 17-hydroxyprogesterone and androstenedione parameters to compare the duration of time subjects have these concentrations outside acceptable ranges.

To determine the maximum tolerated dose (MTD), as a percentage of calories consumed, of triheptanoin (C7 oil; C7) in a pediatric and adult patient population genetically diagnosed with glucose transporter type 1 deficiency disorder (G1D).

The goal of this interventional study was to investigate the impact of daily ingestion of 30g of dark chocolate on omega-3 fatty acid status and gut microbial community in professional soccer players. The main questions it aims to answer are: Can 30g of dark chocolate positively influence the metabolism of polyunsaturated fatty acid (PUFAs) and, particularly, arachidonic acid (AA): eicosapentaenoic acid (EPA) ratio? Can 30g of dark chocolate change the microbial composition in professional soccer players? Elite male soccer players were randomly divided into 2 groups. One group was provided with 30g of dark chocolate 88% (2,5 mg/g of polyphenol) and one group, as control, was provided with with 30g of white chocolate (0 mg/g of polyphenol). Each group ingested the chocolate intervention as a "solid bar" in the morning (before 9:00 am) every day for 4 weeks. The dark chocolate and white chocolate were provided every morning to each subject by the nutritionist of each team, while, during off days, the chocolate was portioned into individual serving sizes and provided to each player. Adherence was checked by the nutritionist. For each assessment, the participants arrived at the training center in the morning, after an overnight fast. Before the beginning and the end of the study, a 3-days food record (3dr) was recorded (2 weekdays and 1 week-end day) by the nutritionist. Blood was collected between 08:00 and 09:00 hours, fecal sample was delivered within the end of the morning, and anthropometry measures were determined.

The aim of the present study is to evaluate the impact of vestibular rehabilitation on metabolic aspects when evaluated by means of bioelectrical impedenzometry analysis, smart watch device and actigraphy in a group of vestibular hypofunction patients previously studied by means of video head impulse test, posturography and clinical validated scales

Considering that the failure of the treatment of obesity is justified by the multifactorial pathophysiology of this morbidity, the present project has the following hypotheses: The occurrence of obesity is due to the derange,ent of mitochondrial energy metabolism ; The unbalance is therapeutically modified through physical training ; Obesity courses with the break-down in energy metabolism mitochondrial disease associated with systemic inflammatory characteristics that can be corrected through a combined long-term physical training program. This study have as objective : to analyse changes in mitochondrial function, inflammatory profile, oxidative stress and energy metabolism caused by concurrent physical training in obese women.

The objective of the present study was to evaluate the impact of a snack bar on some health indicators associated with diet (plasma antioxidant capacity, lipid profile, vitamin A profile (retinol and carotenoids)) and on the nutritional status (impact on energy and nutrients consumed) in a group of upper level students.
