Effect of Exercise-Induced Weight Loss on Energy Metabolism
MetabolismWeight LossThe E-MECHANIC Ancillary Study will measure changes in 24-hour energy expenditure and spontaneous physical activity in a subset of 60 obese individuals enrolled in the main study. We aim to determine if changes in energy metabolism might explain why people don't lose the expected amount of weight in an exercise program.

Impact of Smoke-free Legislation on Early-life Mortality and Low Birth Weight in England
StillbirthInfant Mortality5 moreThe purpose of this study is to investigate whether there has been a change in low birth weight and perinatal and infant mortality following the July 2007 introduction of a ban on smoking in public places and workplaces in England.

Diffusion Weighted Magnetic Resonance Imaging of the Breast During Chemotherapy: Response Evaluation...
Breast CancerEvaluation of the response to chemotherapy in breast cancer patients by the use of Diffusion-weighted magnetic resonance imaging of the breast before the start of chemotherapy, after one and 3 cycles of therapy and at the end of the therapy.

The Optimum Time for Preoxygenation Based on Body Mass Index
Body WeightObesityThe 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).

Changing resistance and incline on an elliptical trainer Ground jogging. Stair climbing. Treadmill running. Walking.

Diffusion Weighted Imaging as a Biomarker for Detection of Chemotherapy Induced Cardiotoxicity
Chemotherapy Induced Cardiotoxicity in Breast Cancer PatientsThe goal of this study is to see if a special type of heart scan called a diffusion weighted magnetic resonance imaging (DW-MRI) that uses extra measurements, can be used to find early signs of heart damage from chemotherapy.

Diffusion MRI; Predictive Value for Cervical Uterine Cancer Recurrence
Uterine Cervical CancerDiffusion-weighted MRI1 moreUterine cervical cancer is the second most common female malignancy. Therapy monitoring is essential to detect early recurrence. Diffusion-weighted magnetic resonance imaging is an emerging MRI imaging technique which has a potential value for the detection of primary and recurrent disease and for the assessment of response to therapy. The purpose of this project is to evaluate the predictive value of DWI during and after therapy in the prediction of recurrence of cervical uterine cancer. It will be considered whether DWI is able to provide early information about the response to therapy. This could enable the identification of less- or non-responsive tumors and in this way therapy can be adapted as soon as possible. Hence the investigators could offer the patient a more efficient treatment scheme and a reduction in toxicity related to the treatment could be established.

Relationship Between Body Weight and Glycohemoglobin
Type 2 Diabetes MellitusControl of body weight (BW) is important to prevent and manage type 2 diabetes. Regardless of the close association, little is understood about the precise relationship between BW and glycemic control, which might be of benefit for patients with type 2 diabetes. The researchers investigated the correlation between changes in BW and glycemic control in patients with type 2 diabetes treated with a diet therapy or pioglitazone.

The Impact of Texas Senate Bill 42 on Middle School Children's Level of Physical Activity
ObesityBody WeightThe purpose of this study was twofold: 1) to assess awareness of and adherence to Texas SB42 among a representative sample of public middle schools in Texas; and 2) to assess the impact of SB42 on the frequency of school PE class, the quality of school PE, and prevalence of child self-reported physical activity behaviors and child overweight along the Texas-Mexico border.

Laparoscopic Revision Gastric Bypass for Inadequate Initial Weight Loss
Inadequate Initial Weight LossPersistent Clinically Severe ObesityThe 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 inadequate initial weight loss.
