Active clinical trials for "Body Weight"

High intake of insoluble fiber is strongly associated with a reduced incidence of diabetes and cardiovascular events in prospective observation studies. Our primary objective is to compare a life style diabetes prevention program(PRAEDIAS) with and without added insoluble fibers in its effectiveness to prevent incident diabetes type 2 in high risk individuals with impaired glucose tolerance. Subjects with IGT not willing to participate in the intervention will be used as independent controls. Secondary aims are to identify mechanisms of action with regard to body composition, anti-inflammatory and metabolic effects of fibers. We propose a randomized, prospective intervention study. The results will be of general relevance for guidance of fiber intake in the population and will help the food industry to design healthy high fiber foods. Fiber can be added at low cost to numerous foods. Increased fiber intake may therefore provide a simple non-cognitive prevention strategy effective at the population level.

The investigators hypothesize exercise increases short term appetite and food intake, and interferes with satiety and satiations to a preload in normal weight, boys.

Preoperative staging for gastric adenocarcinoma is an important procedure to detect advanced disease stateS for the patients in which the surgery may be unnecessary to perform. Although there are many imaging techniques for this purpose, sensitivity and specificity of these techniques still remains to be low.Preoperative detection of peritoneal carcinomatosis and involvement of lymph nodes beyond D2 may prevent surgical procedures. Removal of the determined lymph nodes according to the type of the surgery is the accepted surgical method. However, accurate determination of malignant lymph nodes may prevent dissection of some groups of the lymph nodes. These findings may cause a new definition of gastric lymph node dissection.

The investigators will test the efficacy of a tailored behavioral lifestyle modification program to support cardiovascular health in postpartum women with excessive gestational weight gain. This program will include a mobile health texting component postpartum to support changes in nutrition and physical activity. The investigators will randomize women into either the control arm (usual care) or the intervention (usual care + mobile health program postpartum). The women will be recruited during their 3rd trimester once they have been identified as gaining too much weight according to the 2009 IOM guidelines during pregnancy.

The purpose of this study is to identify how adult men respond to a weight loss diet that includes pork and eggs and increasing the number of meals consumed throughout the day. This is a 13-week study (12-weeks of weight loss and 1-week of baseline measurement).

This study assess whether a small-group seminar intervention to prevent weight gain is effective in a general university student population, and to address the relative role of biological vs. lifestyle factors in predicting weight gain in humans.

The purpose of this study is to examine if single skin cleansing with 0.25% chlorhexidine affects skin condition, temperature, and bacterial colonization in stable preterm (28-36 weeks gestational age) low birth weight (1001-2000 g) infants admitted in a health facility.

The purpose of the present study is to determine whether weight gain may be prevented by a small group seminar-based two-year educational intervention on healthy lifestyle in freshmen at the Faculté de médecine de l'Université de Sherbrooke.

Background Risk factors for cardiometabolic diseases have their onset in infancy. Comorbidities such as overweight, abdominal obesity, hypertension, insulin resistance and elevated triglycerides have been observed in childhood with a tendency to persist into adult life. Furthermore, this situation has generated an increase in morbidity and mortality rates due to chronic non-communicable diseases. One approach to decrease the impact of cardiometabolic diseases is the intervention with exercise training (strength and aerobic capacity), where an important role of protein intake plays a role in influencing the performance of strength training, due to the greater utilization of low-energy protein compared to aerobic exercise. In children, a better tolerance was reported in muscle strength exercises, with at least one supervised training session per week with moderate intensity (20 minutes of physical activity). Currently, there is no consensus on the minimum time required to intervene and achieve significant changes in the metabolic profile of adolescents and children. Objective To evaluate the relationship between weight at birth and adaptations to aerobic exercise and muscular strength, and its effects on metabolic risk, body composition and physical capacity. Methodology An experimental study with individual analysis per participant would be perform. The sample will include a 12 to 17-year-old adolescent population. It will consist of two phases. The intervention will be based on moderate strength, power and resistance training programs, and/or moderate aerobic capacity exercise in circuit steps. The workouts will be done two times a week, approximately 30 to 40 minutes including warm-up, stretching and cooling. All participants personal and family history data would be collected and blood samples would be taken. Potential results Within the expected results, the protocol wants to implement a new methodology of physical capacity training. Furthermore, the protocol will evaluate if related cardiometabolic risk factors with the intervention would improve in target patients at risk of developing cardiometabolic diseases to identify them and prevent the occurrence of these pathologies in adult life.

Computed Tomography (CT) is widely used in abdominal imaging for a variety of indications. Contrast media (CM) is used to enhance vascular structures and organ parenchyma. Attenuation of the liver makes it possible to recognize hypo- and hypervascular lesions, which are often invisible on unenhanced CT images. Lesions can only be detected in case they are large enough and the contrast with the background is high enough. Heiken et al. showed already in 1995 that a difference in Hounsfield Units (HU) of at least 50 HU is needed to be able to recognize liver lesions [1]. On the other hand, patients should not receive more CM than necessarily, because of possible underlying physiological effects [2-4]. Although there has been some controversy about this recently, there is no need to give patients more CM than needed, because of increased costs, no quality improvement and their might still be a relationship with contrast induced nephropathy (CIN) [5]. Recent publications suggested individualization of injection protocols that can be based on either total body weight (TBW) or lean body weight (LBW) [6-9]. In the investigators department an injection protocol based on TBW is currently used. Besides the CM injection parameters, scanner parameters are of influence on the attenuation as well. Because of recent technical developments it became possible to reach a good image quality (IQ) at lower tube voltages [10]. When the x-ray output comes closer to the 33 keV k-edge of Iodine, attenuation increases. In short, decreasing the tube voltage increases the attenuation of iodine. Scanning at a lower tube voltage therefore gives rise to even lower CM volumes. Lastly, it would be revolutionary to accomplish a liver enhancement that is homogenous, sufficient for lesion detection and comparable between patients and in the same patients, regardless of weight and scanner settings used.
