Filter by:Several hormones involved in body weight regulation increase the subject's ability to burn fat for energy. The purpose of this study is to investigate how burning fat for energy may affect those hormones and body weight in children. The study will also determine if eating a diet higher in protein alters the amount of fat you burn and how these hormones control body weight.
The purpose of this study is to evaluate the effect of SCH 497079 on weight in obese and overweight participants. The primary measure of effectiveness is the change in body weight during treatment. Additional measures include waist circumference and body mass index (BMI). In addition, the safety of SCH 497079 in obese and overweight participants will be evaluated. The primary hypothesis is that treatment with SCH 497079 will be more efficacious than that with placebo with respect to the primary efficacy variable.
This is a randomized clinical trial for evaluate the impact of a nutritional intervention in the weight control of pregnant women according to the nutritional status, and consequently, the reduction of pregnancy complications. The sample of this study will be composed by 318 pregnant women in the pre-natal care unit of the Health Center in Viamão city / Rio Grande do Sul, including women between the 10th and 25th weeks of gestation, aged up to 35 years old. The eligible pregnant women will be invited by the fieldworks to participated in the trial after be informed about the overall aims of the study. These women willing to participate will be randomly allocated to either the intervention or control group. The intervention group received specific guidelines about feeding practices appropriate to each nutritional status. Data on pregnant women will be collected through a questionnaire in both groups, and to assess the food intake, three 24-hour food recall will be applied in the interventional group and two recall in the control group, in initial and final gestational period. In all appointments pregnant women of the two groups will be weight and classified according to Body Mass Index of pre-gestational (BMI). The dietary advices will be elaborated by the author of the project and nutrition graduation students of Federal University of Health Science of Porto Alegre.
Background: Use of variable definitions of exercise and disparate results, emphasize the need of proper randomized controlled trials examining the relationship between physical activity and weight development during pregnancy. So far, only few intervention studies aiming at weight management during pregnancy have been performed (Gray-Donald et al., 2000,Olson et al., 2004,Polley et al., 2002,Kinnunen et al., 2007). Moreover, most of these interventions have focused on how gestational weight gain may be altered through individual counselling combining diet and exercise habits, rather than supervised training. Search on PubMed revealed no randomized controlled trial where the main outcome was to investigate how the effect of supervised structured exercise may reduce the proportion of women gaining more weight than optimal. The aim of the present study is to assess whether a 12-week aerobic exercise program during pregnancy can prevent excessive gestational weight gain. Method: This is a single blind randomized controlled trial to evaluate the effects of a structured, supervised aerobic exercise program on weight gain stabilization in primiparous pregnant women. The aim is to include 100 women. Interested women eligible for the present study will be invited to a pre-test including interview and assessments at the university. The women are examined three times during the study period. The first visit is between 12 and 24 weeks of gestation, the second at week 36-38 and the last 8-12 week after delivery. The exercise program consists of supervised exercise for 60 minutes, performed at least 2 times per week, for 12-16 weeks. Compliance with the training protocol is controlled by the instructors and registrations in the womens personal training diary
The aim of the study is to determine mechanisms leading to glutathione deficiency in low birth weight newborn babies. Compared to full term neonates, depletion in this population may be due to a decreased synthesis rate or to an enhanced utilization or a combination of both mechanisms.The protocol is constituted of two steps. The objective of the first step is to quantify the blood concentration of glutathione in the artery and the vein of umbilical cord in full term newborn babies. Objectives of the second step are to determine if the glutathione synthesis rate, measured in vitro, is lower in erythrocytes collected from umbilical cord blood of low weight newborn babies compared to full term newborn babies. In this case, the next objective will be to determine if the adjunction of an excess of cysteine in vitro can restore the glutathione synthesis rate in these cells.
The specific aim of the proposed project is to test two separate self-regulation interventions to prevent weight gain in young adults, one based on making sustained small changes in behavior to prevent weight gain and the other on making periodic larger behavior changes resulting in weight loss.
Objective: To investigate whether recombinant EPO reduces the need for transfusion in extremely low birth weight (ELBW) infants and to determine the optimal time for treatment. The concentrations of trace elements and of antioxidant enzymes were investigated in all patients, too. Study population: 219 patient randomized into 3 groups
Magnetic resonance imaging (MRI) is a diagnostic study that makes pictures of organs of the body using magnetic field and radio frequency pulses that can not be felt. Dynamic contrast enhanced-magnetic resonance imaging (DCE-MRI) uses faster imaging and contrast material (a substance used to make specific organs, blood vessels, or tumors easier to see) that is given by vein. Diffusion weighted magnetic resonance imaging (DW-MRI) allows to measure the motion of water around the cells in the tumor. Proton magnetic resonance spectroscopy (MRS) obtains chemical information from the tumor. During MRS, signals are detected from the chemicals (spectroscopy) naturally present in your tumor using radio waves. DCE-MRI, DW-MRI and MRS give extra information which is not available with the regular MRI. The regular MRI only shows pictures of the tumor while the DCE-MRI also gives information about the blood vessels of the tumor. DW-MRI provides information related to the state of the tumor tissue with regards to the quality or condition of cells present in it and MRS gives information about the chemical makeup of the tumor. The purpose of this study is to see whether DCE-MRI, DW-MRI and MRS done before treatment can predict which patients will do well with either surgery or chemo-radiation therapy. This study will also see if DCE-MRI, DW-MRI and MRS done early in treatment can tell if the therapy is working.
Advances in newborn intensive care have lead to dramatic improvements in survival for the most premature infants—often weighing 1 pound at birth. Unfortunately, cerebral palsy, mental retardation, and developmental delay affect more than 10,000 of these premature infants in the U.S. annually. In his studies, Dr. Jeffrey R. Kaiser is trying to understand why these premature infants are at such high risk of brain injury, and to learn ways to prevent injury. Experts believe that disturbances of brain blood flow regulation are important in causing these injuries. Using a novel continuous monitoring system, Dr. Kaiser is able to determine an infant's capacity for normal brain blood flow regulation. Contrary to previous thinking, he has shown that many of these babies in fact due have normal regulation of their brain blood flow. He has observed that brain blood flow may be disturbed during suctioning of the breathing tube. Further, he has also shown that infants with high carbon dioxide, those not breathing well, have impaired regulation of their brain blood flow. Thus, even stable infants are prone to disturbed brain regulation during routine intensive care, which may lead to bleeding in the brain and long-term neurologic problems. Dr. Kaiser will study up to 200 infants to determine 1) the developmental pattern of normal regulation of cerebral blood flow; 2) in those with impaired regulation, determine when it develops during the first week of life; and 3) determine the relationship between impaired brain blood flow regulation and brain injury. Results from this study will help us recognize when premature infants are most vulnerable to developing brain injury, allowing prevention and intervention strategies to be initiated in a timely fashion.
