17 Clinical Trials for Various Conditions
This study aims to compare the COAST (comprehensive older adult screening tool) to muscle mass as determined by BIA (bioelectric impedance analysis) and thus, determine if the COAST is a valid predictor of muscle loss in older adults. This study follows a comparison of COAST to MNA and will further test the validity of the COAST nutrition screening tool.
This study is being conducted to define the specific nutritional biomarkers and nutritional risk during the course of chemoradiation therapy for cancers of the head and neck. This prospective, longitudinal observational study is focused on specific antioxidants and B vitamins. The ORAC was selected as an index of overall antioxidant capacity. We chose to evaluate antioxidant status because administering antioxidants has been shown to reduce chemotherapeutic agent toxicities.
This research study will be conducted in two parts. The first part will consist of selecting appropriate screening and assessment tools for Veterans undergoing elective surgery and identifying the number of Veterans who are malnourished and at risk of malnutrition. The second portion of the study will be to determine if a protein-enhanced diet before and after surgery will improve function and postoperative outcomes and compare the results to an education control group.
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.
The goal of this randomized controlled trial is to compare the effect of receiving 6 months of monetary support for healthy food through a food delivery platform on change in glycosylated hemoglobin (HbA1c) levels among adults with type 2 diabetes mellitus with glycemic control that is above target level. The main study aims are to: 1. To evaluate whether providing monthly financial support for home-delivered healthy food vs. only free food delivery through the Instacart platform reduces glycosylated hemoglobin levels within 6 months among Medi-Cal-insured Kaiser Permanente adult members with diabetes mellitus and suboptimal glycemic control. 2. To evaluate whether providing monthly financial support for home-delivered healthy food vs. only free food delivery through the Instacart platform reduces medical resource utilization within 6 months among Medi-Cal-insured Kaiser Permanente adult members with diabetes mellitus and suboptimal glycemic control.
This study is designed to evaluate the efficacy of two diets, a low glycemic load diet and a low saturated fat diet, in the treatment of adolescents with some heart disease risk factors associated with being overweight, such as high blood pressure, pre-diabetes, and cholesterol problems. The objective of the study is to determine which diet improves these risk factors more. The design of the study is a modified feeding study, which requests that the participants eat all and only the food provided by the study for 8 weeks, most days per week. Dietary counseling by phone will continue between 2 and 6 months of the study and the effects of this maintenance period will be assessed at 6 months time.
There is a well-documented association between androgen deprivation therapy (ADT) and cardiovascular morbidity. A majority of men on ADT gain weight contributing to an increase in cardiovascular risk factors (CVRFs) and cardiovascular morbidity. Dietary intervention combined with exercise have shown success in reducing weight/fat mass and improving cardiovascular risk factors (CVRF). There is little data on whether African American men would respond to diet and exercise interventions differently from non-Hispanic white men. We will conduct a pilot, controlled two-phase intervention study stratified by race to investigate the following objectives: 1. Compare effect of a hypocaloric, anti-inflammatory diet on changes in fat mass between African- American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. 2. Compare effect of a hypocaloric, anti-inflammatory diet on changes in cardiovascular risk factors (body weight, lean body mass, waist-to-height ratio, blood pressure, lipids and HbA1C) and inflammatory markers (hs-CRP and cytokines) between African-American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. 3. Compare effect of a hypocaloric, anti-inflammatory diet on changes in cancer-related fatigue and quality of life between African-American vs non-Hispanic white men with metastatic prostate cancer on ADT therapy. We will enroll 35 African American and 35 non-Hispanic white men with prostate cancer undergoing ADT therapy. In phase 1, after baseline assessment, men will consume their habitual diet and continue their habitual activity level for 3 months. During phase 2, participants will be instructed to consume a hypocaloric (-500 kcal), anti- inflammatory diet and walk for 1 hour on 3 days per week for 3 months. At baseline, after phase 1 and 2 primary outcome (fat mass) and secondary outcomes (CVRF and inflammatory markers) and tertiary outcomes (cancer-related fatigue and quality of life) will be determined.
US residents who have obesity and sign the informed consent form and are screened and enrolled for this study. Participants who are enrolled complete a survey upon enrollment and are randomized into one of three arms. This study is direct to participant and will not utilize clinical sites.
This study is a virtual, remote, decentralized pragmatic clinical trial comparing the efficacy of medically tailored meals alone or medically tailored meals with remote nutritional counseling compared with usual standard of care in adults with a targeted, nutrition-sensitive chronic medical condition (heart failure, diabetes mellitus, chronic kidney disease).
Individuals who suffer from paralysis after spinal cord injury (SCI) are estimated to have an even greater (66%) prevalence of obesity. Obesity is a major public health concern and is associated with a plethora of cardiometabolic health complications (heart disease, stroke and type II diabetes mellitus). Although the benefits of physical activity to counteract obesity and cardiometabolic disease have been documented, SCI typically limits voluntary exercise to the often injured arms (60-90%). On the other hand, functional electrical stimulation (FES) cycling has proven to be a safe and effective way to exercise paralyzed leg muscles in clinical and home settings, saving the often overworked arms. The investigators have developed a novel high-intensity interval training (HIIT) protocol for FES lower extremities cycling that may provide equal or greater benefits with less time commitment. The investigators proof-of-principle study in 3 obese persons with SCI confirmed that HIIT-FES cycling 3 times per week for 8 weeks without dietary monitoring can increase legs lean mass (5-9%), increase cardiovascular health markers (58% on average) and decrease HbA1c blood levels (2-4%). Also, 2 persons decreased body weight and BMI. The investigators hypothesize that combining HIIT-FES cycling with nutritional counseling will be effective for reducing obesity and enhancing cardiometabolic health in persons with chronic SCI. Research AIM: To determine preliminary efficacy of HIIT-FES cycling combined with nutritional counseling in obese adults with SCI. In this pilot two-arm, parallel, pre-post, subject-matched controlled trial, we will test the hypothesis that the experimental group receiving HIIT-FES cycling plus nutritional counseling will decrease total body weight, decrease body fat percentage, decrease fat mass, increase total and legs lean mass, improve blood lipid levels, decrease blood glucose and HbA1c levels and improve vascular endothelial health (flow mediated dilation) significantly more than age-, sex- and injury-matched controls receiving nutritional counseling only. The investigators will recruit 20 obese adults, 21-65 years of age, with chronic post-traumatic SCI ranging in neurological level between C4 and T12. Participants will be divided into experimental (HIIT-FES cycling plus nutritional counseling) and control (nutritional counseling only) groups.
The overall purpose of this application is to evaluate the efficacy of an intervention designed to decrease health disparities in pregnant, emotionally distressed, minority women. This randomized controlled trial will test a six session (spaced over 18 weeks) cognitive behavioral skills building (CBSB) prenatal care intervention (specifically designed and based on prior research for pregnant minority women experiencing emotional distress) at three sites (Jacobi Medical Center, New York City and The Ohio State University Total Health and Wellness Clinic, and The Ohio State University Wexner Medical Center OB/GYN Columbus, Ohio.
Animal studies have found that vitamin K-dependent proteins matrix Gla protein and osteocalcin beneficially influence lipid and glucose metabolism, respectively. However, this concept has not been tested in humans at risk for dyslipidemia and diabetes risk. Vitamin K supplementation presents an opportunity to test the hypothesized link between the vitamin K-dependent proteins and markers of lipid and glucose metabolism. The investigators will conduct an 8-week vitamin K intervention (to manipulate carboxylation of matrix Gla protein and osteocalcin) and determine its effects on markers of dyslipidemia and diabetes risk. Sixty obese children will be randomly allocated to either the control group receiving placebo or the low-dose (45 mcg/d) or high-dose group (90 mcg/d) receiving vitamin K (menaquinone-7).
The investigators propose to obtain facial photographs for use in testing a computer algorithm that recognizes males at high risk for Hypohidrotic Ectodermal Dysplasia (XLHED). FDNA (www.fdna.com), a software company with expertise in the area of facial recognition, is collaborating with the Sponsor in algorithm development based on 2D photographs not requiring special photographic technologies. A frontal facial photograph will be taken at the time of study conduct. The anonymized photographs will be transmitted to FDNA for analysis. A limited number of unaffected controls will be also be recruited. A subset of affected males between ages 5 and 25 years will have the option of having a blood draw for a set of laboratory studies assessing nutritional status.
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.
The purpose of this study is to test whether compounds found in strawberries (polyphenolics which are typically found in berry products, tea, coffee, red wine, and chocolate) will help reduce insulin resistance and inflammation, known factors in your blood associated with disease risk, when eaten with a standard high fat/carbohydrate meal.
Type 1 Diabetes (T1D) is an autoimmune disease. This means that the immune system (the part of the body which helps fight infections) mistakenly attacks and destroys the cells that produce insulin (islet cells found in the pancreas). As these cells are destroyed, the body's ability to produce insulin decreases. The autoimmune process is thought to be initiated by a gene-environment interaction. The genetics involved in the development of T1D are fairly well understood. There is a higher risk of developing T1D with the presence of the human leukocyte antigen (HLA) DR3 or DR4. It is also known that not everyone with these genes actually develops T1D. Therefore, one or more environmental factors are thought to contribute to the process of developing T1D. The consumption of the anti-inflammatory fatty acids, the omega-3 fatty acids, has decreased significantly in the past 100 years. At the same time a rise in the incidence of T1D, especially in young children has occurred. Because of the warnings to eliminate fish during pregnancy, pregnant women are consuming even less omega-3 fatty acids during fetal development. Observations have been made that children who have received omega-3 fatty acid supplementation have a lower risk of T1D. Omega-3 fatty acids could have a protective effect that may occur during pregnancy, infancy, or both. The mechanism of this protection may be due to the DHA mediated suppression of the inflammatory response. Patients at higher risk for T1D have an increased pro-inflammatory environment. We hypothesize that DHA supplementation during pregnancy and early childhood will block the initial pro-inflammatory events and prevent development of islet cell autoimmunity in children at higher risk for T1D. This study is a feasibility study to determine if a full-scale DHA supplementation study will be implemented. If a full study is implemented, the primary outcome will be to determine if nutritional supplementation with omega-3 fatty acids during the last trimester of a mother's pregnancy and/or the first three years of life for children who are at higher risk of T1D will prevent the development of islet autoimmunity.
The goal of this study is to compare the impact of a SMART ((specific, measurable, attainable, realistic, or timely) Goal setting protocol on body weight, metabolic parameters (Hemoglobin A1c, lipids), diet quality and physical activity frequency in obese children with prediabetes in the outpatient setting. The main question is if participants using the SMART Goal Setting Protocol (SGSP) will have a significant reduction. The participants randomized to the study group will receive the SGSP, consisting of the SMART Goal Selection Guide (SGSG) and Weekly Goal Monitoring Tool (WGMT), in BMI Z-score, A1c, and dyslipidemia in 6 months compared to controls.
