NCT01207687
People who have neurofibromatosis type 2 (NF2) can have tumors that grow on the auditory nerves and cause hearing loss. These tumors are called vestibular schwannomas (VSs), or acoustic neuromas. People with NF2 can also get schwannomas in other parts of their body, as well as tumors called meningiomas and ependymomas. Because VSs can cause hearing loss, many people with NF2 will have treatment to preserve their hearing. This treatment usually involves surgery. Because surgery has risks and is not able to help everyone with VSs, other methods of treatment are being explored. One area of exploration is looking to see if there is a drug that can be taken that might prevent the VSs from growing larger and causing hearing loss or brainstem compression. This study is exploring whether a drug that is approved by the FDA and is currently used to treat other tumors might also work to treat VSs. Based on people who have taken this drug to treat VSs already, there is some reason to think that it might be helpful to certain people with NF2. People enrolled in this study will receive the drug one time every three weeks for one year by infusion. This study will follow subjects over the course of the year that the person is taking the drug and for six months after the drug is stopped. This study is recruiting people who have NF2 and are currently having symptoms of tinnitus, dizziness, and/or hearing loss from their VSs. If you have NF2 and are currently having symptoms caused by your VSs, you may be eligible to participate.
NCT01383642
Vestibular dysfunction is a known contributor to imbalance and fall risk, and may be a precursor to the frailty phenotype seen in the elderly population. A recent study found that vestibular dysfunction is common in the US population, and that the prevalence of this impairment increases steeply with age. However, it is unknown whether the aging process has global effects on the vestibular end-organ or whether specific structures, e.g. the semicircular canals or the otoliths, are selectively impaired. Moreover, the clinical implications of specific deficits of the vestibular end-organ are unclear. As such, the aims of this proposed research are: 1) to evaluate whether the normative aging process is predominantly associated with dysfunction of the semicircular canals (as measured by caloric and angular vestibulo-ocular reflex testing) or of the otoliths (as measured by vestibular-evoked myogenic potential (VEMP) testing); 2) to determine if there are any characteristic clinical features associated with the subtypes of vestibular dysfunction; and 3) to assess whether dysfunction of the semicircular canals or of the otoliths is associated with a higher risk of frailty and falls. The investigators plan to pursue these aims through a cross-sectional and prospective cohort study of a group of individuals age 70 and above. Vestibular physiologic tests will be administered to all study participants, and test results will be correlated with baseline clinical symptoms and frailty status as well as prospective one-year fall risk. A greater understanding of vestibular physiologic deficits and clinical implications in older individuals can inform the development of rational vestibular rehabilitation strategies that may more effectively mitigate the frailty phenotype and reduce fall risk.
NCT00289783

NCT02051465
Colorectal cancer accounted for 142,570 new cancer cases and 51,370 cancer deaths in USA in 2010 and worldwide has become the third most common cancer and second leading cause of cancer related deaths. Colonic adenomatous polyps are known precursors of colorectal cancer and endoscopic removal of the polyps prevents development of colon cancer. Removal of such large polyps requires special endoscopic techniques-endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), which are more technically difficult to perform, labor intensive, time consuming and carries higher risks of complications (bleeding, perforations, etc.). The purpose of this study is to determine the effectiveness and safety of the LumenR Retractor in performing EMR and ESD. It is hypothesized that the use of this modified colonic overtube will simplify colonoscopic removal of difficult polyps, decrease the time needed to complete the procedure and decrease the rate of complications post endoscopic removal of large and flat colonic.
NCT01871805

NCT01335932
To evaluate whether administration of ganciclovir reduces serum IL-6 levels (i.e. reduction between baseline and 14 days post-randomization) in immunocompetent adults with severe sepsis or trauma associated respiratory failure. Primary Hypotheses: \- In CMV seropositive adults with severe sepsis or trauma , pulmonary and systemic CMV reactivation amplifies and perpetuates both lung and systemic inflammation mediated through specific cytokines, and contributes to pulmonary injury and multiorgan system failure, AND \- Prevention of CMV reactivation with ganciclovir decreases pulmonary and systemic inflammatory cytokines that are important in the pathogenesis of sepsis and trauma related complications.
NCT00129129
This study is evaluating the safety and immunogenicity of GSK Biologicals' Hib-MenCY-TT vaccine compared to a control group receiving licensed Hib conjugate vaccine, each administered at 2, 4, and 6 months of age, and compared to licensed meningococcal serogroups A, C, Y, and W-135 polysaccharide vaccine administered at 3 to 5 years of age. The safety and immunogenicity of a booster dose of Hib-MenCY-TT vaccine will be compared to a booster dose of licensed Hib conjugate vaccine, each administered at 12 to 15 months of age. The group primed with the Hib conjugate vaccine will re-randomized at 12-15 months of age to receive a booster dose of Hib-MenCY-TT or a booster dose of the Hib conjugate vaccine.

NCT01636453
To assess the safety and effectiveness of the Penumbra Liberty Stent System as adjunctive treatment to embolic coils for wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA). The Liberty Stent System is an implantable device comprised of a stent and delivery system designed as an adjunct to embolic coils in the treatment of wide-neck, saccular, intracranial aneurysms. It has three components: an implant, an introducer sheath and a delivery wire assembly. The implant component is made of superelastic and biocompatible nitinol tubular material. Patients presenting with wide-neck, saccular, intracranial aneurysms in the internal carotid artery (ICA) from the cavernous segment to the carotid terminus (including the paraclinoid, ophthalmic, hypophyseal and posterior communicating segments) will receive stent assisted coiling by the Penumbra Liberty Stent with any approved embolic coils currently on the market. Wide-neck aneurysms are defined by a neck ≥4mm or a dome-to-neck ratio \<2. Each patient will be followed and assessed for 2, 6 and 12 months after enrollment.
NCT01473771
The purpose of this multi-site randomized controlled trial is to determine if the Caring Letters intervention is effective in preventing suicide and suicidal behaviors among U.S. Service Members and Veterans. The primary aim of this project is determine whether caring communications following inpatient psychiatric treatment reduce suicide and self-inflicted injuries among U.S. military personnel and Veterans. The investigators will also explore treatment utilization by comparing the frequency of treatment visits after enrollment into the study. The following specific hypotheses will be tested: Hypothesis 1: During a two year follow-up after the index hospital discharge, the frequency of suicide will be lower among participants in the Caring Letters group compared to those in the Usual Care group. Hypothesis 2: The frequency of medically admitted self-inflicted injuries will also be lower in the Caring Letters group compared to the Usual Care group. Hypothesis 3: The time to suicidal act, among those who do subsequently exhibit one, will be longer among participants in the Caring Letters group compared to the Usual Care group.
NCT02273037
A novel handheld Doppler has been developed which is rugged and is powered only by a hand crank. This study aims to test the use of this Doppler versus the Pinard horn to monitor the fetal heart rate in labour in a hospital setting in Uganda. The investigators propose that with its ease of use, both for the woman and midwife, midwives using the Doppler will identify more babies in need of prompt delivery and the risk of stillbirth and neonatal mortality will decline. In the research study, the investigators will compare the risk of stillbirths and neonatal mortality in two randomized groups of labouring women. The second part of the study consists of an audit of the documentation in labour by midwives. The partograph is an uncomplicated, low cost form on which observations during labour are documented. It includes three sections of information: fetal condition, maternal condition and labour progress. Although the use of a partograph during labour is strongly recommended by the WHO, there are limited published systematic evaluations of the correct use of the tool. The investigators aim to use this randomized trial design to assess rates of intrapartum stillbirth and neonatal mortality in the first 24 hours after delivery, and assess the quality of partographs comparing two groups. This trial will provide insights on the potential benefits of using handheld Doppler devices for intrapartum monitoring, and the audit of partograph quality will provide insights to improve care during labour. This study hypothesizes that the quality of partograph completion and of fetal heart rate monitoring may systematically differ between the Doppler and Pinard groups.
NCT01985243
Despite recent economic growth in Ghana, the prevalence of childhood malnutrition remains high. Wasting prevalence affected 29% among 6- to 8-months-old infants in 2008. Poor nutrition contributes to about one-third of child mortality, diminishes cognitive development, and is a major determinant of maternal mortality. The specific objectives of the 5-year project are to: (1) enhance human capacity of government, civil, and private institutions through improvement of knowledge and skills of personnel in agriculture, nutrition and health, entrepreneurship, and pedagogy; (2) identify information needs of local institutions that are not presently met and develop a representative and sustainable longitudinal data system to support evidence-based decision-making in programs; (3) increase vulnerable households' access to quality services in agriculture/fisheries, nutrition and health, and finance; (4) implement integrated intervention activities to improve infant and young child and adolescent nutrition outcomes; and (5) examine differential benefits of the interventions for diverse vulnerable populations. The project comprises two major activities: part I - the creation of a longitudinal data system to support evidence-based decision-making in programs, and part II - the implementation of intervention activities to improve nutrition outcomes. The survey will include demographic, socioeconomic, health, diet, and nutritional status information collected annually from a representative same of 1500 households with infants (0-12 mo) and 1500 households with adolescents (9-12 y). The data will be analyzed and presented rapidly each year to district program and policy leaders to assist them in developing their activity plans for the following year.
