Active clinical trials for "Body Weight"

This is a completely text-messaging based study and all data will be collected via surveys administered on a mobile phone. For this study, we will gather and analyze data on changes in body weight over a 6-month interval in individuals aged 12 and over. This will help us learn more about the normal variation in weight, over time, in the PWS population.

This study aimed to examine the relation between trunk control and gross motor performance in LBW and NBW infants.

Background: Osteoporotic fractures are a major public health issue. They cause substantial disability, loss of autonomy, morbidity and excess mortality. Diabetes is also associated with increased risk for falls and fractures through a direct impact of elevated blood glucose on the skeleton and on muscles. Research project overview: The investigators propose a cross-sectional study that will involve 2 research centers in the province of Quebec. The investigators will recruit 20 obese participants, without diabetes, who have not undergone bariatric surgery, for one-time measurements to be compared with baseline measurements (pre-surgery) from participants in the bariatric obese diabetic groups with type II diabetes mellitus from the ongoing study BODI study (NCT03455868). Bone Mineral Density as well as muscle quality, strength and function will be evaluated at a single study visit. Relevance: This data will permit the evaluation of the bone-muscle unit in patients with obesity with and without diabetes, and assess whether the presence and duration of diabetes impacts further on clinical and functional musculoskeletal outcomes (falls, fractures and mobility and strength) in this population. AGEs, if associated with muscle and bone deterioration, might become an easily accessible biomarker of musculoskeletal health in the clinical setting.

Given the dismal prognosis of pancreatic cancer, detecting liver metastases early can avoid inappropriate therapy with the associated substantial risks, long-term hospital admissions and high costs, but without survival benefit. The current standard of diagnostic workup with contrast-enhanced CT (CECT) has a poor sensitivity (38-76%) for the detection of liver metastases. As more sophisticated and expensive treatment options emerge, better staging of pancreatic cancer is needed to avoid unnecessary procedures and select the most appropriate treatment strategy. New imaging modalities are available, but their value in staging of pancreatic cancer has not been evaluated yet. Therefore prospective imaging studies are necessary. The main aim of this study is to determine the diagnostic accuracy of contrast-enhanced diffusion-weighted MRI (CE-DW-MRI) in the detection of liver metastases in patients with pancreatic cancer compared to a reference standard of histopathology and follow up imaging. The study is an international, multicenter prospective cohort study (inclusion of patients until 138 patients with liver metastases are included, with a total maximum of 465 patients). Patients with pancreatic cancer will undergo additional CE-DW-MRI within two weeks from the CECT. CECT and CE-DW-MRI will be read independently by two radiologists. Suspected liver lesions on CECT and/or CE-DW-MRI will be biopsied to obtain histopathology as reference standard. For liver lesions without histopathologic proof of metastases a paired follow-up CECT and CE-DW-MRI serve as a composite reference standard. Pancreatic resection will be pursued in patients without proven liver or distant metastases. Patients with locally advanced or metastatic disease will be offered palliative treatment. Follow up CECT and CE-DW-MRI will be performed in all patients at 3, 6, and 12 months.

Diffusion weighted imaging (DWI) can reflect the microstructure and pathological changes of tissue, and diffusion tensor imaging (DTI) can quantitatively evaluate the fine structure of white matter in brain. In this study, conventional and diffusion-weighted MRI (DWI, DTI) sequences were used to analyze the brain of monochorionic twin pregnancies with demise of one fetus.

The purpose of this project is to examine potential bias or expectancies in individuals' measurement and recording of weight in a clinical-research setting.

The main aim of this study is to analyze and report traditional, patient-centered, and composite intermediate-term outcomes after laparoscopic revision Roux-en-Y gastric bypass surgery for weight recidivism.

The aim of this study is to measure important components of weight change in patients who underwent bariatric surgery on measures of fat mass and its distribution and fat-free mass (FFM) (bone mineral density, skeletal muscle, and specific organs) at 60 months (T60) and 84 months (T84) post-surgery, and to compare compartment sizes with stable weight controls.

This study is part of an effort to learn about interactions between doctors and patients. We aim to understand how women feel about techniques that doctors use to talk with patients about their weight. We are studying women s reactions to these techniques using a virtual reality version of a doctor s office to create as realistic a model of a doctor s visit as possible. This can help us better understand what happens during real doctor s visits. Women between the ages of 20 and 50 who are currently overweight may be eligible for this study. Participants will be recruited from the Washington D.C. area. This is not a weight treatment study. Participants undergo the following procedures: Complete an online questionnaire about themselves, their experiences, and their thoughts about their weight Participate in activities in a virtual reality environment in which they interact with a virtual doctor in a virtual clinical scenario. For this experiment, participants wear a head-mounted display that allows them to see the virtual world images. Fill out a questionnaire after completing the virtual reality activities. This questionnaire includes information on the participants' virtual reality experience, the information provided in the experience, and additional questions about themselves and their thoughts.

Type 2 Diabetes Mellitus (T2DM) and Gestational Diabetes Mellitus (GDM) create complications during pregnancy, particularly in women with gestational weight gain (GWG) that falls over the recommended limit. On the other hand Medical nutrition therapy (MNT) has been shown to reduce some complications in women with T2DM and GDM. The aim of this project was to assess the association of MNT consultations and eating behavior with GWG in Mexican women with T2DM and GDM.
