NCT ID: NCT05443347 Recruiting - Obesity Clinical Trials

Activity, Adiposity, and Appetite in Adolescents 2 Intervention

AAAA2 INT
Start date: September 14, 2022
Phase: N/A
Study type: Interventional

The objective of the study is to quantify the relationship between physical activity, metabolic function, and appetite in adolescents. To do this we will test our working hypothesis that high levels of regular moderate-to-vigorous physical activity (MVPA), as opposed to body weight status, results in a metabolic phenotype consisting of enhanced metabolic function and proper regulation of appetite. We will randomly assigning sedentary overweight/obese adolescents (N=44) to either a control or structured-exercise group for three months.

NCT ID: NCT05307367 Recruiting - Quality of Life Clinical Trials

Cancer-associated Muscle Mass - Molecular Factors and Exercise Mechanisms

PANACEA
Start date: April 1, 2022
Phase: N/A
Study type: Interventional

Muscle mass loss is a common adverse effect of cancer. Muscle mass loss occurs with or without reduction in body weight. Cancer cachexia (CC) is the involuntary loss of body weight of >5% within 6 months and it occurs in 50-80% of patients with metastatic cancer. It is estimated that CC is a direct cause of up to 30% of all cancer-related deaths. No treatment currently is available to prevent CC, likely because the chemical reactions that causes of this devastating phenomenon in unknown. No treatment currently is available to prevent muscle mass loss in patients with cancer but is urgently needed as the reduced muscle mass and function is associated with impaired physical function, reduced tolerance to anticancer therapy, poor quality of life (QoL), and reduced survival. There is evidence of an interdependence between informal caregiver (e.g. spouse) and patient QoL. Thus, identifying caregiver distress and needs can potentially benefit QoL for patients with cancer cachexia. Despite the enormous impact on disease outcomes, it is not known why the loss of muscle mass and function occurs and very few studies have investigated the underlying molecular causes in humans. In particular, there is a severe lack of studies that have obtained human skeletal muscle and adipose tissue sample material. Such reference sample materials will be invaluable to obtaining in-depth molecular information about the underlying molecular causes of the involuntary but common muscle mass and fat mass loss in cancer. At a whole body level, cancer cachexia is associated with reduced sensitivity to the hormone insulin, high levels of lipids in the blood, and inflammation. Within the skeletal muscle, the muscle mass loss is associated with elevated protein breakdown and reduced protein build-up while emerging, yet, limited data also suggest malfunction of the power plants of the cells called mitochondrions. The role of malnutrition and how it contributes to weight loss is understood only to the extent of the observed loss of appetite and the reduced food intake because of pain, nausea, candidiasis of the mouth, and breathlessness. Evidence is increasing that the environment of the intestinal system could be implicated in cancer cachexia, yet, the possible effect of cancer and the cancer treatment on the intestinal environment is not understood. Thus, large and as yet poorly understood details of this syndrome precede a later weight loss. Exercise training could help restore muscle function and how the chemical reactions works in cancer. In healthy people, and patients with diabetes, cardiovascular disease, and obesity exercise potently improves health. Exercise has been thought to slow down the unwanted effects of cancer cachexia by changing the reactions mentioned above. Thus, there is a tremendous gap in our knowledge of how and if exercise can restore the cells power plants function, muscle mass, strength, and hormone sensitivity in human cachexic skeletal muscle. Tackling that problem and examining potential mechanisms, will enable us to harness the benefits of exercise for optimizing the treatment of patients with cancer. The data will provide novel clinical knowledge on cachexia in cancer and therefore addressing a fundamental societal problem. Three specific aims will be addressed in corresponding work packages (WPs): - investigate the involvement of hormone sensitivity of insulin and measure the chemical reactions between the cells in patients with lung cancer (NSCLC) and describe the physical performance and measure amount of e.g. muscles and adipose tissue across the 1st type of cancer treatment and understand how that is related to the disease and how patients and informal caregiver feel (WP1). - find changes in the chemical reactions in skeletal muscle, adipose tissue (AT), and blood samples in these patients, to understand how to predict how the disease will develop (WP2). - measure changes of skeletal muscle tissue in response to exercise and see if it might reverse the hormone insensitivity and improve muscle signaling and function (WP3). The investigators believe that: - the majority of patients with advanced lung cancer, at the time of diagnosis already are in a cachectic state, where they lose appetite, and have hormonal changes, and an overall altered chemical actions between the cells affecting both muscle mass and AT. The investigators propose that all this can predict how the disease will progress, and how patient- and informal caregiver fell and how they rate their quality of life. - lung cancer and the treatment thereof is linked with changes in the blood, the muscle tissues, and the adipose tissues, especially in patients experiencing cachexia, that could be targeted to develop new treatment. - exercise can restore the muscles and improve insulin sensitivity and improve the function of the cells power plants in patients with lung cancer-associated muscle problems.

NCT ID: NCT05009433 Recruiting - Depression Clinical Trials

HIIT vs MICT During Pregnancy and Health and Birth Outcomes in Mothers and Children

HIIT MAMA
Start date: June 24, 2021
Phase: N/A
Study type: Interventional

Regular exercise during pregnancy and postpartum leads to health benefits for mother and child. Inactivity during pregnancy and after delivery is now treated as risky behavior. Physically active pregnant women significantly less often suffer from, among others, gestational diabetes, excessive weight gain, lipids disorders, hypertension, preeclampsia, depressive symptoms, functional and structural disorders, including stress urinary incontinence, back pain or diastasis recti abdominis (DRA). Prenatal physical activity reduces the risk of premature delivery and miscarriage, fetal macrosomia, complications in labor or the risk of metabolic disorders in children. High-intensity interval training (HIIT) has become one of the most popular trends in the fitness sector. The effectiveness of HIIT on a number of health indicators has been proven in various populations but limited data are available on HIIT during pregnancy. The first hypothesis is that the HIIT, implemented during pregnancy and after childbirth, as a stronger exercise stimulus, will have a better impact on selected biological and psychological parameters of mothers, as well as on selected health parameters of their children, compared to the MICT (moderate intensity continuous training). Therefore, it promises better preventive effects on pregnancy complications and ailments as well as non-communicable diseases occurring in these populations. In the second hypothesis, it was assumed that HIIT and MICT implemented during pregnancy and after childbirth, tailored to the specific needs of the perinatal period, will not differ in the effectiveness of maintaining normal functional parameters in women, including prevention of urinary incontinence, back pain, DRA, etc. Pregnant women who apply for the study will be divided into three groups: those attending the HIIT, MICT or educational programs. During the study, the participants will be under standard obstetric care. As comparative groups, non-pregnant women will be also recruited. The investigators will collect data on selected biological, functional and psychological parameters in the study women at each trimester of pregnancy, during the puerperium and one year after childbirth. The data from the medical documentation on the course of childbirth and the assessment of the new-born, as well as the results of preventive examinations in the study women's children aged one, two, four and six years will be also analyzed.

NCT ID: NCT04735835 Recruiting - Healthy Clinical Trials

Personalized Responses to Dietary Composition Trial 3

Start date: July 20, 2020
Phase: N/A
Study type: Interventional

The PREDICT 3 study will build on previous research in over 2,000 individuals to further refine machine learning models that predict individual responses to foods, with the aim of advancing precision nutrition science and individualized dietary advice. The study incorporates both standardized and controlled dietary intervention, for the purpose of testing postprandial responses to specific mixed meals, in addition to a free-living period with a dietary record for measuring responses to a large variety of meals consumed in a realistic context, where the role of external factors (e.g. exercise, sleep, time of day) on postprandial responses may be determined. For the first time this PREDICT study is built on top of a commercial product which will allow access to a much larger group of participants who are already collecting large amounts of data through digital and biochemical devices that can contribute to science.

NCT ID: NCT04482556 Recruiting - Clinical trials for Mechanical Ventilation

Comparison of the Q-NRG+ Indirect Calorimetry Device Versus the V(Max) Encore Device in Mechanically Ventilated Children

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

The overarching aim of this proposal is to examine the feasibility of the Q-NRG+ indirect calorimetry device and its agreement with (Vmax) Encore indirect calorimetry device in mechanically ventilated children. The overall hypothesis of this study is that the Q-NRG+ will provide minute-to-minute oxygen consumption (VO2) and carbon dioxide production (CO2) measurements that are in agreement with those obtained by the standard indirect calorimetry device currently used at our institution (Vmax Encore).

NCT ID: NCT04281407 Recruiting - Metabolism Clinical Trials

Impact of Probiotics on Drug, Vitamin, and Hormone Metabolism

NCT ID: NCT04178681 Recruiting - Nutrition Clinical Trials

Postprandial Effects of Milk Fats

POEMI
Start date: December 2, 2019
Phase: N/A
Study type: Interventional

Nowadays, mostly vegetable fat blends are used in infant formula, but the use of bovine milk fat is increasing. In terms of fat structure, bovine milk fat and vegetable fats differ. Bovine milk fat has a higher percentage of palmitic acid attached to the sn-2 position of the glycerol backbone compared to vegetable fat blend. Also bovine milk fat contains milk fat globular membranes, as opposed to vegetable fat. With this study the investigators want to examine the effects of a vegetable fat blend versus bovine milk fat without globular membranes and bovine milk fat with globular membranes on underlying mechanistic, immune and metabolic responses.

NCT ID: NCT04055428 Recruiting - Clinical trials for Cardiovascular Diseases

NAUTICAL: Effect of Natriuretic Peptide Augmentation on Cardiometabolic Health in Black Individuals

Start date: August 15, 2020
Phase: Phase 2
Study type: Interventional

Black individuals are more likely to have decreased insulin sensitivity which results in a high risk for the development of cardiometabolic disease. The reasons for this are incompletely understood. Natriuretic peptides (NPs) are hormones produced by the heart that play a role in regulating the metabolic health of an individual. Low circulating level of NPs is an important contributor to increased risk for diabetes. The NP levels are relatively lower among Black individuals thus affecting their metabolic health and putting them at a higher risk for diabetes. This study aims to test the hypothesis that by augmenting NP levels using sacubitril/valsartan, among Black Individuals one can improve their metabolic health (as measured by insulin sensitivity & energy expenditure) and help establish the role of NPs in the underlying mechanism behind increased risk for cardiometabolic disease in these population.
