47 Clinical Trials for Various Conditions
This is a randomized, double-blind, placebo-controlled, 5-arm parallel-group study to evaluate the effects of 4 nutritional supplements on sleep over a 12 week period in healthy U.S. adults.
Purpura is a macule or papule of blood in the skin. It is mostly seen in mature skin that is often prone to significant bruising. Small lesions of less than 5 mm are called petechiae and larger ones, found mostly in subcutaneous tissue, are called ecchymosis. Actinic purpura occurs almost exclusively in elderly populations. This single-blind randomized clinical trial evaluates the effect of an 8-week nutritional supplement intervention in comparison with isolated vitamin C supplements on actinic purpura in older adults. We will enroll thirty (30) otherwise healthy participants, both male and female, aged 55 years and older. Changes in participants' skin condition will be assessed at visit 1 (baseline), visit 2 (4-week), and visit 3 (8-week) using questionnaires, standard digital photography, and clinical grading of the skin lesions.
Better understanding of the duration needed to overcome metabolic disturbances in patients experiencing exacerbation. Also, the explore role of nutritional intervention in the treatment program of stable COPD patients and in those recovering from an acute exacerbation (AECOPD) is important to restore loss of muscle mass and function and to reduce readmission and hospitalization rate of these patients, thereby leading to improved clinical and overall outcome as well as reduction of health care costs.
This study is a randomized controlled trial comparing outcomes between geriatric hip fractures who received a commercially available (XR RecoveryTM, Salt Lake City Utah) peri-operative nutritional supplement for three weeks post-operatively to those who receive standard nutritional counseling. The main question it aims to answer is: - Does supplementation decrease muscle loss via ultrasound measurements of the cross-sectional area of the rectus femoris of the uninjured leg?
The purpose of this study was to assess the usefulness of protein and carbohydrate supplementation, with and without creatine, on occupational performance in firefighters. Research has examined the effects of adding creatine to whey protein and carbohydrates on training adaptations in resistance-trained individuals with mixed finding. Furthermore, the ergogenic benefit of protein and carbohydrate supplementation, with or without creatine, in firefighters is largely unknown. Therefore, the primary aim of the current study was to examine the effects of protein and carbohydrate supplementation, with or without creatine, on occupational performance in firefighters.
This phase I clinical trial tests the immune effects of fermented wheat germ in patients with advanced solid tumor cancers who are being treated with standard of care checkpoint inhibitors. Fermented wheat germ is a nutritional supplement that some claim is a "dietary food for special medical purposes for cancer patients" to support them in treatment. There have also been claims that fermented wheat germ is "clinically proven" and "recognized by medical experts" to "enhance oncological treatment" and boost immune response to cancer; however, there are currently no documented therapeutic effects of fermented wheat germ as a nutritional supplement. Checkpoint inhibitors, given as part of standard of care for advanced solid tumors, are a type of immunotherapy that may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. The information gained from this trial may allow researchers to determine if there is any value of giving fermented wheat germ with standard of care checkpoint inhibitors for patients with advanced solid tumor malignancies.
The objective of this randomized, controlled trial is to evaluate the effects of consuming a pediatric oral nutritional supplement (ONS) plus dietary counseling for 120 days on anthropometric growth, strength, and nutritional status, compared with dietary counseling alone in undernourished children in the United States.
This non-randomized pilot study aims to investigate whether a protein rich nutritional shake (Ensure Enlive) given to patients pre-transplant will decrease skeletal muscle loss (measured by quadriceps ultrasound) and improve nutritional state (measured by Nutritional Risk Index). A nutritional supplement would be a cost-effective solution to treat malnutrition, a known risk factor implicated in poor outcomes for lung transplant recipients.
Many elderly experience weight loss and weakness with normal aging. Although there is extensive literature regarding nutritional advice for the elderly, there are few well- designed studies evaluating the effect of oral nutrition supplements in patients with weight loss and aging. The aim of this study is to examine the effect of dietary prescription with or without nutrition supplementation that includes soy protein, whey protein and fish oil in elderly patients who have suffered unintentional weight loss.
The main purpose of this research study is to determine if the use of a nutritional supplement and exercise improve or worsen cachexia.
The purpose of this study is to evaluate the combined effects of diabetes self-management education (DSME) and nutritional supplementation on visual function and retinopathy incidence \& progression in patients with type 1 diabetes, type 2 diabetes and pre-diabetes.
The study evaluated the safety, tolerability and acceptability of a lifestyle modification program with nutritional supplementation designed to restore balance to healthy bowel function in generally healthy subjects
Many older adults do not get enough zinc, vitamin C and vitamin D, and this can be related to decreased ability to fight infection. The purpose of this research study is to determine if taking a multivitamin/mineral supplement every day for 12 weeks will increase the ability of immune cells in blood to kill bacteria.
The aim of this study is to investigate the acute effects of ingestion of carbohydrates - with different glycemic profiles - on cognitive function among preadolescent children (i.e., 9-10 years).
Compare an over-the-counter dietary supplement (NutraStem Active®) and placebo over a 30-day intervention on aerobic exercise performance and fatigue. The hypothesis is that supplementation with NutraStem Active® improve aerobic performance and reduce subjective measures of fatigue.
This study will investigate the effect of an oral nutritional supplement (ONS) along with dietary counseling on improving the dietary intake among children with picky eating behaviors.
The ability of older adults to improve their muscle strength through exercise training appears related to how well their immune system functions. Thus, a nutritional supplement which improves immune function could theoretically boost strength gained for older adults from exercise. The purpose of this pilot study is to determine if a nutritional supplement has any effect on immune function. Veterans (age 60-80 yrs, N=12) be randomized in a double-blind placebo-controlled fashion to consume supplement or placebo for four weeks. After two weeks of consumption, subjects will be treated with a vaccine for tetanus, diphtheria, and pertussis. Blood will be drawn from each subject before and after vaccination to determine the effects of the supplement on immune response to vaccination. Additionally, subjects will undergo blood draw and muscle biopsy before and after two weeks of supplementation to determine the effects of supplementation on other measures of immune function (e.g. cytokine and growth factor levels). This is an important issue due to the serious health consequences associated with muscle loss in older adults and the need for improved strategies for rehabilitation.
Nutritional supplementation is more effective than placebo in the reduction of redness and bruising following facial ablative laser resurfacing treatments and following soft tissue filler injections to the lips and/or malar areas.
The purpose of this multisite randomized controlled trial (RCT) is to compare the short-term (6 week) and long-term (6 month) effect of chiropractic care combined with a specific nutritional supplement regimen to chiropractic care with a placebo supplement for patients with ankle sprains, in terms of improvement in physical function and pain.
Rotator Injury: * Strength/range of Motion * ASES, VAS
Several trials have found that nutritional supplementation can elicit an increased rate of skeletal muscle protein synthesis following a single bout of exercise in both young and older individuals. However, there have been no studies that have investigated if nutritional supplementation and exercise can cause a sustained increase in physical functioning and fat free mass, particularly in older adults with functional limitations. This study will compare the effects of a nutritional supplement versus a placebo on exercise training induced changes in physical functioning older adults who are at risk for mobility disability.
This is a nonblinded Case-only study that evaluates the effects of Agmatine Sulfate on small fiber peripheral neuropathy. Patients will be started on Agmatine sulfate (a metabolite of Arginine) and monitored for two months. Improvement will be noted on their response to the Neuropathic Pain Questionnaire. Additionally the investigators will note improvement by performing autonomic function testing at the beginning and end of the study.
The purpose of this study is to identify the influence of resistance and aerobic exercise with different nutritional supplements in middle-aged men and women on various physiological measures. Throughout the study, the investigators examine body composition, body weight, food intake, fitness level, metabolism, and blood hormones.
To evaluate the effect of supplemented berry fruit juice and whole fruit berry powder on memory performance and brain function in older adults
The purpose of the study is to compare two different nutritional supplements with respect to their effect on building muscle, and to determine the factors that control the rate at which muscle tissue can be produced in subjects with cancer. After three days of receiving all meals from the Reynolds Institute on Aging in order to stabilize their diet, subjects will then return to the Institute to perform a single day study, where they will be given one of two supplements to drink. Blood will be taken from a catheter placed in one of their arms and three muscle biopsy samples will be taken from a leg. Subjects will have x-ray evidence of cancer and be 40 years of age or older in order to participate. It is the hypothesis that a nutritional supplement with a high amount of protein and containing leucine will target the metabolism problems in cancer patients.
The goal of this study is to evaluate the metabolic effects of concomitant use of three consecutive doses of recombinant human growth hormone over three days and exercise during continuous nutrient infusion in chronic hemodialysis patients. We would also like to evaluate the metabolic effects of nutritional supplementation alone without the additional anabolic strategies.
In this study, the investigators hypothesize that long-term administration of adequate intradialytic oral nutritional supplementation will increase visceral protein concentrations and somatic protein stores in malnourished chronic hemodialysis patients.
The purpose of this study is to determine the effects of nooLVL containing arginine and inositol supplementation on executive function and memory prior to and following playing video games.
A novel prehabilitation method has been implemented at our institution to decrease perioperative outcome complications for frail complex spine fusion surgery patients. The goal of this randomized trial is to evaluate whether this prehabilitation program improves preoperative functional status of frail spine disease patients and benefits patients in their postsurgical outcomes.
The goal of this clinical trial is to prospectively evaluate the effects of essential amino acid (EAA) supplementation on the volume and structure of the muscles surrounding the spine (paraspinal musculature). The main questions it aims to answer are: * Does EAA supplementation preserve paraspinal muscle volume (PMV) and influence changes to spinal alignment following lumbar spine surgery? * Does preserving paraspinal muscle volume (PMV) improve post-operative functional status? * Does preserving PMV reduce post-operative complications, pain, and opioid consumption? Participants will be asked to: * Consume either EAA supplement or placebo (alanine) twice daily for one week before and two weeks after lumbar spine surgery * Record pain levels and medication use in a diary * Perform functional assessments at routine follow-up visits after surgery * Undergo blood draws to monitor nutrition status and health * Undergo one spine magnetic resonance imaging (MRI) before surgery as part of routine surgical planning * Undergo one additional spine MRI after surgery to monitor PMV after treatment Researchers will compare the group that consumed EAA supplement and the group that consumed placebo to see if there is a difference in paraspinal muscle volume changes and measures of spinal alignment, functional abilities, pain levels, and opioid use.
