NCT02770118
The goal of this proposed research is to test the hypothesis that long-term mild sleep restriction (SR), as occurs frequently in adults and adolescents, leads to a positive energy balance and weight gain. Aim 1. To determine the effects of SR, relative to habitual sleep (HS), on food choice and energy intake (EI) in adults at risk of obesity. * Hypothesis 1a. EI, assessed by multiple weekly 24-hour recalls, will be greater during a period of SR relative to HS. This will be mostly due to increased fat and carbohydrate intakes. * Hypothesis 1b. Neuronal responses to food stimuli, assessed by functional MRI (fMRI) after 6 weeks of SR or HS, will indicate increased activity in networks associated with reward and food valuation (insula, orbitofrontal cortex) during a period of SR relative to HS. These responses will be correlated with intakes of high carbohydrate and high fat foods (hypothesis 1a) and neuropeptide Y (NPY). Moreover, activation of the default mode network (DMN) will be suppressed to a lesser extent after SR compared to HS. Aim 2. To determine the effects of SR, relative to HS, on energy expenditure (EE) via independent and complementary approaches. * Hypothesis 2a. EE, assessed by doubly-labeled water (DLW), and physical activity level, monitored daily by actigraphy, will be lower during SR relative to HS. * Hypothesis 2b. Brown adipose tissue (BAT), assessed by positron emission tomography and magnetic resonance combined scanner (PET/MR) using 18F-fluorodeoxyglucose (18FDG-PET) and fat fraction (FF) measurement under cold stimulation, will be greater after SR relative to HS. This would suggest higher adaptive thermogenesis after SR compared to HS. BAT activation will also be correlated with NPY. Aim 3. To determine whether SR alters body weight and adiposity relative to HS. * Hypothesis 3a. SR will lead to weight gain and increased total adiposity, as assessed using magnetic resonance imaging (MRI), relative to HS. * Hypothesis 3b. Increased adiposity after SR will be correlated to an adverse cardio-metabolic risk profile (increased glucose, insulin, triglycerides, leptin, reduced high-density lipoprotein cholesterol and adiponectin) and neuronal responses to food stimuli (Hypothesis 1b), and EE (Hypothesis 2a \& 2b). Failure to stimulate BAT with SR will be associated with greater gain in adiposity.
NCT01288014
After immunization, particularly in older persons, some people are protected from disease by a vaccine and others are not. The investigators believe that this variable response may be due to overproduction of molecules that suppress development of immunity (antibodies and cell mediated immunity). Normally, these molecules are produced to make sure that immunity is regulated in just the right way for the body as a whole, and to prevent autoimmune disease. However, with aging, the immune system may have difficulty in proper immune regulation. Over production of immunosuppressive molecules after vaccination may interfere with the effects of a vaccine. For example when elderly individuals are immunized against zoster with a licensed vaccine, Zostavax, the vaccine is effective in only about 50 to 60%. The investigators will compare blood levels of antibodies, cellular immunity, and immunosuppressive molecules in recipients of Zostavax to see if there is a correlation between development low immunity and high levels of immunosuppressive molecules.

This is a Phase 2 study of oral dacomitinib given every 12 hours over days 1-4 of each two-week cycle to patients with Non-small cell lung cancer. The study includes two groups of patients, those whose tumor has a documented T790M mutation, and those without this mutation. All patients will receive repeated cycles of dacomitinib until disease progression, occurrence of unacceptable toxicity, or other withdrawal criteria are met.
NCT02267629
This research study tests whether GLYX-13 - an experimental drug that acts on a brain receptor called NMDA - can decrease symptoms of OCD within hours. This is not a treatment study. Results from this study will allow doctors and researchers to better understand if you and others with OCD may respond to a class of medications that target the NMDA brain receptor.
NCT01335490
The purpose of the study is to understand how cooking might affect the health of pregnant women and their babies. The goal of the research is to determine whether, interventions in decreasing exposure to smoke from cook stoves can bring about a significant change in the indoor air pollution levels and health of communities in Ghana. Hypothesis 1. Use of improved cook stoves starting by the third trimester pregnancy will lead to a significant increase in average birth weight in newborns. Hypothesis 2. Use of improved cook stoves will lead to a significant reduction in the rate of severe acute lower respiratory disease during the first 12 months of life.
NCT03219229
Young children have a high resting energy expenditure (REE) relative to their body weight and metabolically active compartment, fat-free mass (FFM). Both body weight and FFM are, however, metabolically heterogeneous and include organs and tissues varying widely in specific metabolic rate (i.e., organ REE/kg/d). One prevailing hypothesis is that most, if not all, of the higher REE observed in young animals and children compared to adults can be accounted for by a larger proportion of high metabolic rate components such as brain, liver, and heart..
NCT02042053
This study intents to provide an initial evaluation of the utility of positron emission tomography and magnetic resonance (PET/MR) imaging measures for the prediction of immunological response to Sipuleucel T (SipT) therapy.
NCT00988442

NCT01723423
The MROC Study seeks to evaluate and compare from the patient's point of view the leading options for breast reconstruction after mastectomy. This study will help patients, physicians, payers and policy makers better understand the various surgeries available for breast reconstruction. Although many women choose reconstruction, the number of options as well as their pros and cons can make decision making difficult and stressful. From this research, we hope to learn more about what works best for patients undergoing these operations.
NCT00033397
RATIONALE: Comparing results of diagnostic procedures performed before, during, and after chemotherapy may help doctors predict a patient's response to treatment and help plan the most effective treatment. PURPOSE: Diagnostic trial to study magnetic resonance imaging (MRI) and biomarkers in women who are receiving chemotherapy before surgery for locally advanced breast cancer.
NCT02688452

NCT02364700
This is an interventional pilot study investigating the feasibility of using the hand of hope (HOH) device for individuals with decreased hand function after stroke.
NCT00500695
This project will assess the utility of a brief motivational intervention to engage smokers with schizophrenia in treatment for tobacco dependence treatment. It is hypothesized that a brief motivational intervention will be more effective in engaging smokers with schizophrenia to tobacco dependence treatment than an educational intervention. The educational intervention will increase the likelihood to reducing cigarette intake and/or attending tobacco dependence treatment by teaching subjects about the negative effects of smoking and the success of tobacco dependence treatment. The motivational intervention will increase the likelihood to reducing cigarette intake and/or attending tobacco dependence treatment by increasing subjects' motivation to change by presenting objective and personalized information regarding their smoking behaviors in a non-judgmental and supportive manner.
NCT00501007
The primary purpose of this investigation is to determine the predictive value of task persistence as measured by a mirror tracing task. A secondary purpose is to evaluate differences in task persistence in smokers with or without schizophrenia. It is hypothesized that task persistence in smokers in both diagnostic categories (schizophrenia and no schizophrenia) will predict tobacco dependence treatment outcome at one and six months. It is also hypothesized that smokers with schizophrenia will show lower levels of task persistence after controlling for other motor skills than smokers without schizophrenia.
NCT00792922
Trachoma, an ocular infection caused by C. trachomatis, is the second leading infectious cause of blindness worldwide. Years of repeated infection with C. trachomatis cause the eyelid to scar and contract and ultimately to rotate inward such that the eyelashes rub against the eyeball and abrade the cornea (trichiasis). The World Health Organization (WHO) has endorsed a multi-faceted strategy to combat trachoma, which includes the use of antibiotic treatment to reduce the community pool of infection with C. trachomatis. The objective of this study is to conduct a randomized, community-based trial in three countries (Niger, Tanzania and The Gambia), representing different baseline endemicities, of alternative coverages and frequencies of administration of mass antibiotic treatment as well as to determine the cost-effectiveness of these different strategies from a program perspective.
NCT01054599
Many patients with epilepsy have memory deficits in the setting of otherwise normal intelligence. Unfortunately, the treatment options for memory dysfunction in patients with epilepsy are limited. The investigators are conducting a study to evaluate the effects of memantine for the treatment of verbal memory dysfunction in subjects with localization-related seizures. The study involves randomization to memantine therapy or placebo, with cognitive testing and EEG pre- and post-treatment, as well as after an open-label memantine treatment phase. The primary aim of this study is to evaluate the efficacy of memantine for the treatment of verbal memory dysfunction in subjects with left temporal lobe epilepsy. The investigators expect that verbal memory task performance will improve in those taking memantine, but not in those taking a placebo. The investigators propose that the expected benefit of memantine is specific to verbal memory in subjects with left temporal lobe seizures, rather than representing an overall improvement in cognitive function. The investigators expect no improvement on other cognitive tasks in either the memantine or placebo groups. The investigators will evaluate whether subjects with left temporal lobe epilepsy and memory difficulties have self-reported improvement in memory while taking memantine. The investigators expect improvement of self-rated memory function on the Quality of Life in Epilepsy Patient Inventory (QOLIE-89) in the memantine group, but no change on this scale in the placebo group.
