There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Background: Endocrine disorders occur when the glands that make hormones do not work properly. Hormones levels that are too high or too low can cause problems such as late or early puberty, irregular periods, and infertility. Environmental factors - including pollution; chemical exposure at home and work; foods; medicines; and sleep habits - may cause problems with the endocrine and reproductive systems. Objective: To learn how environmental factors may affect the endocrine and reproductive systems. Eligibility: Males or females, referring to sex assigned at birth, aged 8 years and older; they must have hypogonadism, infertility, or other reproductive disorders. Design: Adult participants will have 4 to 5 visits in 5 years. Children may have up to 12 visits; they may remain in the study up to the age of 23. Most visits will be less than 3 hours. Participants will be screened. They will have a physical exam. They will have blood and urine tests. They will complete questionnaires; they will answer questions about their diet, health, and other topics. Some may be referred for additional tests, such as imaging scans and semen analysis. Specific tests conducted during study visits will vary, depending on the participant s diagnosis. In addition to repeated blood and urine tests, these may include: Body composition measure: Participants will sit in a pod-shaped machine for about 6 minutes. The machines measures the air inside the capsule to record body fat and breathing volume. Resting energy expenditure test: Participants will lie down with a clear dome placed over their head. They will breathe quietly for 30 minutes. This test measures the number of calories their body burns at rest. ...
The purpose of this protocol is to study the efficacy of hiatal closure for early GERD disease. The study team hypothesizes that hiatal closure for early GERD disease is an efficacious treatment of GERD.
Foods that release glucose rapidly, leading to spikes in blood sugar and insulin (known as high glycemic index foods), generate lower satiety responses than foods with low glycemic index. High glycemic index foods are also linked to an increased risk of developing diabetes. The partial replacement of carbohydrates in rich staple foods with soy flour has the potential to reduce glycemic response and improve satiety. In many regions of Latin America, as well as in the Middle East and North Africa (MENA) regions, bread is the staple source of calories, but it is a relatively poor source of balanced nutrition. Bread enriched with soy flour could provide higher dietary protein while moderating blood glucose (and insulin) spikes, which can help reduce insulin resistance and metabolic diseases. The results of this study could provide government and private human nutritionists with the evidence they need to formulate soy flour into bread, corn tortillas, and arepas for schools and homes.
The purpose of this study is to determine whether SMDS patients treated with NR at the proposed dose exhibit decreased glucose uptake in the aorta, to determine if NR treatment results in measurable changes of blood NAD+ and NR levels, to determine if aortic measurements are stable after treatment with NR and to evaluate the safety and tolerability of NR in SMDS patients.
ACT18018 is a multinational, randomized, double-blind, placebo-controlled, parallel-group, Phase 2 study with 3 treatment groups. The purpose of this study is to evaluate efficacy, safety and tolerability with 2 dosing regimens of itepekimab compared with placebo in male and/or female participants with NCFB aged 18 years of age up to 85 years of age (inclusive). Study details include: - The study duration (screening, 24-52-week treatment, 20-week safety follow-up) will be up to 47-77 weeks. - The treatment duration will be up to 24-52 weeks. - The follow-up duration will be 20 weeks. - Site/phone visits are at a monthly interval.
The purpose is to optimize the EMPOWER program by integrating strategies to reduce food cravings, a critical yet often overlooked factor for long-term success in weight management. The objective of this study is to determine the efficacy of craving coping strategies on weight loss outcomes by conducting a randomized controlled trial. Participants will be randomized to receive one of the two strategies to manage food cravings.
This is a health services intervention study aimed at understanding the impact of intensive multi-disciplinary care compared with standard care on patient-reported symptom outcomes and prognostic awareness in patients with brain metastases.
This study is open to adults between 18 and 65 with a type of depression (major depressive disorder) for whom previous treatments for depression did not work. The purpose of the study is to find out whether a medicine called BI 1569912 helps people with depression. Participants continue their standard therapy throughout the study. Participants are put into 4 groups by chance. 3 of the 4 groups take different doses of BI 1569912. 1 group takes placebo. Placebo tablets looks like BI 1569912 but do not contain any medicine. Participants take the tablets once a day for 6 weeks. Participants are in the study for about 2 to 4 and a half months. During this time, they visit the study site at least 6 times. At the visits, doctors ask participants about their symptoms. The participants answer questions about their depression symptoms. The results are compared between the groups. The doctors also regularly check the general health of participants.
Assess the effect of skin rewarming during lower body negative pressure upon arterial blood pressure and tolerance to simulated blood loss after exercise in the cold.
This study investigates the immune profile of patients receiving treatment with venetoclax plus azacitidine for acute myeloid leukemia (AML). Studying the information gathered from the immune profile from blood and bone marrow samples may help researchers understand the associated responses to the treatment of patients undergoing therapy of venetoclax plus azacitidine and create future immune based treatment approaches.
