Filter by:The overall purpose of this research is to test whether adding a supplement to the feeding of extremely low birth weight infant (infants weighing less than 2 pound 2 oz at birth) will help him/her achieve full feeding faster and achieve better weight gain.
Study design: Double blind, randomized, placebo controlled study.The proposed study will consist of two main segments: 1. Segment 1 is aimed to assess the effect of 6-12 months treatment with nutritional supplementation standardized formula, in short and lean prepubertal children on weight SDS, height SDS, BMI SDS and growth velocity 2. Segment 2 is aimed to explore the eating behavior of idiopathic short stature and lean prepubertal children against their sibling who have a normal height and body weight and to find out whether there is a difference in eating patterns and quality of life between idiopathic short stature and lean prepubertal children and children with normal height and body weight Segment 1 Population: 200 subjects and controls will be recruited to segment 1 of the proposed study, 100 at each group. Participants will be recruited from healthy children who will be referred to either the institute for endocrinology or the gastroenterology unit, at Schneider Children's Medical Center for growth assessment, due to low height and weight, in whom, no gastrointestinal morbidity or other underlying cause was found. Methods: Randomization & Blinding: Participants will be randomly assigned either to the intervention group or the placebo control group. Randomization for the two study groups will be made in a ratio of 1:1. Both participants and study team will be blinded to the type of treatment that each patient will receive during the first 6 months of the study. Treatment: Participants in the intervention group will be treated with a nutritional supplementation standardized formula.Participants in the control group will be instructed to consume the same volume of formula as was calculated if they were in the intervention group. Treatment duration: The study will be divided into two treatment periods: 6 months of intervention versus active placebo followed with additional 6 months (an extension period), in which participants at the intervention group will be offered to extend the intervention period and participants at the control arm will be offered to switch to the intervention group. Study Schedule: Follow up visits will take place at 0, 3, 6, 9 and 12 months and will include: 1. Demographic data, medical history and growth data (month 0): Demographic parameters, including birth date, gender, birth weight and length for gestational age, medical history and growth data, including height velocity, parent's and sibling's weight and height will be documented from patient's file. 2. Nutritional assessment 3. Anthropometric assessment (months 0, 3, 6, 9 12): 1. Height without shoes 2. Length 3. Weight with light cloths and without shoes 4. MAC 5. Body mass index (BMI) will be calculated from children's weight and height and age and gender specific BMI SDS will be calculated 6. Body composition assessment using the method of bioelectrical impedance 4. Laboratory parameters (months 0, 6 and 12): 5. Sleeping Questionaire Segment 2: 86 subjects and controls will be recruited to segment 2 of the proposed study Population: Short and lean prepubertal children participating at segment 1 of the study and who are at study entry under 10th percentile in height, when the weight percentile is equal or smaller to the height percentile. Only participants from segment 1 who have siblings with normal height and body weight for age and gender, will be able to participate in segment 2 of the study Control group 1: Sibling of participants in segment 1 of the study, who have a normal height- above 25th percentile and normal BMI for age and gender- above 5th percentile and under 85th percentile. Control group 2: Healthy children from the community who have a normal height above 25th percentile and normal BMI for age and gender above 5th percentile and under 85th percentile Segment 2 of the study will be designed as a case- control study and will focus on the eating patterns, sleeping patterns and quality of life of participants at segment 1 at time 0 month of the study, before the beginning of the nutrition intervention. These findings will be compared to data of a control group, which will be comprised of siblings of participants in segment 1, with normal height and body weight which are matched in age.
You are invited to take part in a research study about the role of leptin (a fat cell hormone that normally circulates in the blood) on maintaining a reduced body weight. This study will also evaluate how leptin impacts hormone levels, metabolic rate (how many calories are used at rest), autonomic nervous function (the part of your brain that controls your heart rate and breathing), changes in body composition and your sense of appetite. Under normal conditions, leptin is secreted by fat cells and signals to the brain to decrease appetite and regulate energy usage and hormone levels. When obese individuals lose weight, their leptin levels go down, which may cause them to later regain the weight. This study will provide leptin as an investigational medication (not yet approved by the Food and Drug Administration) to increase the levels of the leptin hormone that normally circulates in your blood back to a normal range. We will see if this can help you to maintain your reduced body weight and improve your hormonal and metabolic function.
The prevalence of obesity in young adults has been increasing, and excessive body weight have been linked to numerous chronic conditions including cardiovascular disease, diabetes, many forms of cancer, and numerous musculoskeletal problems. This study will focus of the development and evaluation of interventions that may be appropriate for young adults (age 18-35 years) to improve weight loss outcomes following a 24 month intervention. The primary aim of this study is to examine whether an enhanced weight loss intervention (EWLI) that includes technology components results in improved weight loss in young adults (18-35 years of age) compared to a standard behavioral weight loss intervention (SBWP) over a period of 24 months. Eligible participants will also be assessed for body composition, body fat distribution, fitness, physical activity, dietary intake, and behavioral/psychosocial measures that may be predictive of behavior change. Assessments will occur at 0, 6, 12, 18, and 24 months. Subjects will participate in a 24 month behavioral weight loss program that includes a reduction in energy intake and moderate-to-vigorous intensity exercise (progressively increasing from 100 to 300 minutes per week). The technologies added to EWLI are text messaging, a wearable device that provides feedback on physical activity, and access to a website to monitor dietary behaviors.
Roux-and-Y gastric bypass is one of the most common forms of bariatric surgery; due to a reduction in size of the stomach and intestine, the available surface area for the absorption of oral drugs is strongly decreased. This may lead to a reduced bioavailability resulting in a reduced efficacy of the drug. However, in literature there is no information available about the impact of bariatric surgery on the pharmacokinetics of moxifloxacin. This protocol evaluates the moxifloxacin plasma levels, the variability between subjects and the absolute bioavailability, after oral administration of 400 mg moxifloxacin in healthy volunteers who have had a gastric bypass at least 6 months ago and who now have a stable body weight.
The objective of this clinical trial is to in determining weight-bearing deficits following anterior cruciate ligament reconstruction.
This clinical trial will assess growth, tolerance and adverse events of cow milk-based infant formulas in healthy, term infants.
Study goal is to determine whether behavioral lifestyle intervention during pregnancy can reduce the number of women who exceed the Institute of Medicine recommendations for weight gain during pregnancy. It is hypothesized that the intervention will reduce the number of women who exceed weight gain guidelines relative to standard care. The investigators also expect the intervention to reduce the proportion of women exceeding weight gain guidelines in both normal weight and overweight groups.
The purpose of this study is to evaluate the relationship between the time needed to raise the oxygen concentration in patient's blood to 90% and his/or her body mass index. The prevalence of obesity in our society continues to rise. No studies have shown the time required for preoxygenation (oxygen given) in relation to body mass index (body weight in kg/height in meter2).
