NCT00883909
ARI103094 is a follow-up study in adult male subjects who have received investigational product (either dutasteride or placebo) in the REDUCE Study (REduction by DUasteride of prostate Cancer Events), ARI40006, A Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study of the Efficacy and Safety of Dutasteride 0.5mg Administered Orally Once Daily for Four Years to Reduce the Risk of Biopsy-Detectable Prostate Cancer. There are 2 parts to this REDUCE Follow-Up Study, Part A and Part B: * REDUCE Follow-Up Study, Part A, is a 2 year observational study which will follow eligible subjects for 2 years after completion of the 4 Contact in the REDUCE study. Eligible subjects for Part A, the 2 Year Observational Study fall into 3 groups as follows: (1) REDUCE subjects who completed treatment with investigational product (dutasteride or placebo) through the REDUCE 4 Year study visit \[Visit 10\], (2) REDUCE subjects who developed prostate cancer, were withdrawn from investigational product and participated in Prostate Cancer follow-up until the REDUCE 4 Year study visit \[Visit 10P\] or (3) REDUCE subjects who were withdrawn from investigational product and participated in observational phone follow up until the REDUCE 4 Year phone call after withdrawing from IP (expected Visit 10). The objective of this observational study for eligible REDUCE subjects is to collect and summarize data on prostate cancer (the incidence of newly diagnosed prostate cancers and changes in prostate cancer diagnosed during the REDUCE study) and serious adverse events (SAEs) for 2 years beyond the prospectively planned 4 year double blind, placebo-controlled study, REDUCE. * REDUCE Follow-Up Study, Part B, is for collection of cancer positive prostate biopsy tissue blocks/slides from subjects who were diagnosed with prostate cancer in the REDUCE study.
NCT01910792
Patients with fat malabsorption due to Crohn's disease, ulcerative colitis, or other causes including cystic fibrosis, among others, or who have undergone gastric bypass have increased incidence of vitamin D deficiency relative to the general population. Given that vitamin D is fat soluble and absorbed in the proximal small intestine, it has been documented that vitamin D deficiency in people with a fat malabsorption syndrome is due to decreased absorption of vitamin D. The amount of vitamin D produced from winter sunlight (in Boston, MA) and dietary sources will negligibly raise blood vitamin D levels in these patients, and oral vitamin D supplementation may have limited efficacy due to malabsorption. A variety of UV light sources have been developed and sold as in-home tanning devices and to produce vitamin D in reptiles. The efficacy of correcting vitamin D deficiency by the skin exposure to an artificial source of UVB radiation in patients with fat malabsorption syndromes (Crohn's disease, ulcerative colitis, or cystic fibrosis) or after gastric bypass surgery has not been studied. The investigators have conducted a pilot study in healthy adults that demonstrated that exposure to the lamp raised the blood level of 25-hydroxyvitamin D with no side effects. The main purpose of this study is to evaluate the effect of the FDA approved artificial source of ultraviolet (UVB) radiation (Sperti® lamp) in improving vitamin D status in patients with fat malabsorption syndromes and patients who have undergone roux-en-Y gastric bypass surgery.
NCT00345332

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.
NCT00047294
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Thalidomide and celecoxib may stop the growth of tumor cells by stopping blood flow to the tumor and may increase the effectiveness of temozolomide by making tumor cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of combining temozolomide, thalidomide, and celecoxib following radiation therapy in treating patients who have newly diagnosed glioblastoma multiforme.
NCT02856737
Delirium is an acute disturbance in mental abilities and confusion that affects many patient in the hospital and is caused by multiple factors including and altered sleep/wake cycles and multiple sedating medications. Patients in the ICU are particularly susceptible to developing delirium due to increased noise levels and metabolic derangements. Numerous studies have shown that delirium can be associated with many negative outcomes, including longer hospital length of stay, increased time on a ventilator, higher mortality rates, and greater long-term cognitive dysfunction. There are a series of non-pharmacological interventions that have been shown to reduce delirium especially in intensive care units. These include noise reduction, frequent reorientation, reducing unnecessary stimulation at night, and grouping patient care procedures. The aim of this study is to evaluate the benefits of eye masks and earplugs (used concurrently) on reducing delirium and to assess for associated outcomes such as length of stay, use of sedating medications, morbidity, and mortality. The benefits of this are to improve sleep quality, and this intervention has been associated with a reduction in the risk of delirium.
NCT00008346
RATIONALE: Screening tests may help doctors detect cancer cells early and plan more effective treatment for cancer. It is not yet known which type of mammography is more effective in detecting breast cancer. PURPOSE: Screening and diagnostic trial to compare the effectiveness of two types of mammography in detecting breast cancer in women.
NCT02484703
This study will evaluate the safety, tolerability, efficacy, and pharmacokinetic and pharmacodynamic activity of 3 different dosages of RO5186582 compared with placebo. A total of approximately 46 participants will be enrolled, in order to have at least 32 evaluable, and will be randomly assigned to 1 of 4 treatments in a 1:1:1:1 ratio, with 9 children per treatment arm. The target ratio between 6-8 years and 9-11 years age groups is approximately 1:1 in each treatment arm, with a minimum of 3 children per age group in each treatment arm.
NCT01354132
The investigators seek to examine the effect of add-on N-Acetyl-Cysteine (NAC) in the early phase of schizophrenia spectrum illness in collaboration with researchers Kim Do, PhD, and Philippe Conus, MD in Switzerland. Modifications of brain structure are thought to occur during the pre-illness phase and around the transition to psychosis. Therefore, studying new treatments that could target changes occurring during this period is of critical importance. Aims: Does add-on NAC treatment in early psychosis influence: * positive and negative symptoms * extrapyramidal side-effects of other medication * plasma concentration of glutathione * Mismatch Negativity, a physiological marker
NCT00339638
This study will identify chemical and protein markers in the blood of people who carry the human T-lymphotropic virus type I (HTLV-I), a virus associated with various pathologies, including an increased risk in adults of a rare and aggressive cancer called adult T cell leukemia/lymphoma (ATL). The study will also examine differences in these markers before and after the onset of ATL. ATL has been reported in every area where HTLV-1 is common, including the Caribbean and parts of Japan, West Africa, the Middle East, South America, and Pacific Melanesia. Risk factors for the disease are largely unknown and seem to vary among those affected in different endemic regions. People who acquire the infection early in life are thought to be at higher risk than those who are infected later. In Japan, men seem to be at greater risk than women, but the same is not evident among the black population in the Caribbean and Brazil. Findings from this study will increase understanding of the cause of ATL and identify differences in tumor characteristics and the course of disease across geographical areas. Study subjects are drawn from among participants in eight studies of HTLV-1 carriers, including the 1) Jamaica Mother-Infant Cohort Study, 2) Jamaica Family Study, 3) Jamaica Food Handlers Study, 4) Miyazaki Cohort Study in Japan, 5) Nagasaki Cohort Study in Japan, 6) Japan Public Health Center-based Prospective Study on Cancer and Cardiovascular Disease, 7) HTLV Outcome Studies in the United States, and 8) GIPH Cohort Study in Brazil. Stored blood samples previously collected from patients in the above studies who did and did not develop ATL will be analyzed for immunologic and genetic factors.
NCT00833976
This is an open-label pilot study of omega-3 fatty acids (Lovaza) for hypertriglyceridemia in subjects who have been on an atypical (second-generation) antipsychotic medication. The investigators hypotheses are that patients who receive Lovaza will experience a significant decrease in triglycerides from baseline. Secondary hypotheses include: Patients will experience a significant decrease in total cholesterol, and Lovaza will be well tolerated.
NCT01522235
The purpose of the study is to see if administering intravenous immune globulin (IVIG) (putting immune globulin directly into your blood) helps to improve the symptoms of orthostatic hypotension (sudden fall in blood pressure when a person stands up) and quality of life in men and women who have autoimmune autonomic ganglionopathy (AAG).

NCT00001192
This study will allow researchers to use various types of tests to evaluate cognitive and sensory functions. These tests, referred to as "batteries" will evaluate attention, executive functions, general intellectual functioning, language, memory, motor functions, orientation, personality, selected sensory and perceptual functions, vigilance (alertness), and visual-spatial functions. Children and adult patient will receive different test batteries. The goals of this research study are to; 1. Create descriptions based on the performance of each patient on the test batteries. Then use this information to relate patient behavior to their neurophysiological, neuroradiological, and biochemical descriptions. 2. Define subgroups of patients based on their neurobehavior in order to decrease the variability of psychiatric diagnoses, treatments, and prognoses.
