NCT00135707
Preeclampsia is one of the most common complications of pregnancy and is characterized by high blood pressure and protein in the urine. This can cause problems in the second half of pregnancy for both the mother and fetus. This study of preeclampsia consists of two parts: 1) a randomized, placebo controlled, multicenter clinical trial of 10,000 low-risk nulliparous women between 9 and 16 weeks gestation and 2) an observational, cohort study of 4,000 patients between 9 and 12 weeks gestation who are also enrolled in the trial. Subjects in both parts will receive either 1000 mg of vitamin C and 400 IU of vitamin E or matching placebo daily. The purpose of the randomized, clinical trial is to find out if high doses of vitamin C and E will reduce the risk of preeclampsia and other problems associated with the disease. The study will also evaluate the safety of antioxidant therapy for mother and infant. Patients will be seen monthly to receive their supply of study drug, to have weight and blood pressure recorded, to have urine protein measured, and to assess any side effects. At two visits, blood and urine will be collected. The observational, cohort study will prospectively measure potential biochemical and biophysical markers that might predict preeclampsia. These patients will have additional procedures including uterine artery Doppler and blood drawn for a complete blood count (CBC).
NCT01925482
This study will measure the speed at which gases move between the middle-ear air-space and the blood flowing through the middle-ear lining. The middle ear is a rigid biological gas pocket located behind the eardrum and is filled with the same gases as in air, primarily oxygen (O), nitrogen (N) and carbon dioxide (CO2), but in different proportions. The middle ear is lined by a thin layer of cells overlying tissues that surround blood vessels. The blood that flows through the middle-ear lining also contains these same gases but at different proportions from both the atmosphere (room air) and middle ear. Because of the differences in the proportions of these gases, each gas tends to flow between the middle ear and blood trying to make the proportions of gases in those compartments the same. This flow of gases to and from the middle ear changes the middle-ear pressure. If the middle-ear pressure decreases much below the air pressure of the atmosphere, the ability to hear sounds is impaired and fluid can build up in the middle ear. It is expected that each different gas will move between the middle ear and blood at a different speed, but it is not known what those speeds are for any of the gases. It is also expected that those speeds will be different for ears that have had middle-ear disease and those that have not. In this study, we will measure the speed of nitrogen, oxygen and carbon dioxide exchanges in both directions between the middle ear and blood. To do this, the gas mixture in the middle ear will be changed so that there is movement of only one gas for each experiment and then measure the change in the amount of the gas in the middle ear. This can be done using a special instrument called a mass spectrometer if there is an open, working tympanostomy (ventilation) tube, a small plastic tube, in the eardrum. For all participants in this study, we will conduct 6 experiments lasting about 2 hours each to measure the speed of nitrogen, oxygen and carbon dioxide flow. Subjects with and without tympanostomy tubes will be recruited. Those without a tube will have a tube inserted in one ear for study purposes and it will be removed at the end of the study; these subjects will be followed weekly until the hole in the eardrum (where the tube was) is closed.
NCT00833170
The purpose of the Pediatric Inflammatory Bowel Disease Collaborative Research Group Registry is to study the contemporary natural history of children \<16 years of age newly diagnosed with inflammatory bowel disease.

NCT02665468
On October 1, 2016, the VHA Office of Telehealth and the Connected Health Office will merge to create a single entity that will be responsible for the implementation and evaluation of eHealth technologies across the healthcare system. In an effort to successfully fulfill its mission, the new combined Connected Health/Telehealth Office is pledging $1,100,000 for an eHealth Partnered Evaluation Initiative (PEI) to support the further implementation of eHealth technologies across VHA, and to measure their impacts on dimensions of access and other outcomes. Developed in close consultation with leadership of the new office, the proposed objectives of the eHealth PEI are to (1) implement a patient-level "supported adoption intervention" for secure messaging and evaluate the impact of secure messaging use through a rapid, one-year randomized trial; and (2) evaluate the initial rollout of VHA's automated telehealth text messaging system to Veterans and clinical team members.

NCT01523587
This randomised, open-label phase III trial will be performed in patients with advanced squamous cell carcinoma of the lung requiring second-line treatment after receiving first-line platinum-based chemotherapy. The primary objective of this trial is to compare the efficacy of BIBW 2992 to erlotinib as second-line treatment in this group of patients.

NCT01817712
The primary objective of CSP#589 VIP-STAR is to evaluate the effectiveness of Individual Placement \& Support (IPS) in unemployed Veterans with PTSD. The primary hypothesis is that, compared to those treated with transitional work program (TWP), unemployed Veterans with PTSD treated with IPS will be significantly more likely to become a steady worker. A steady worker is defined as holding a competitive job for greater than or equal to 50% of the 18-month study follow-up period (i.e., greater than or equal to 39 of the 78 weeks). All participants will be followed for 18 months post-randomization. 12/14/12: Analytic plan augmented to allow for a sensitivity analysis of the primary outcome that would exclude the first 12 weeks post-randomization, and evaluate between group proportion of steady worker status, as defined by working in a competitive job for greater than or equal to 50% of the weeks during week 13-78. 7/1/13: Analysis plan has been augmented to include a logistic regression analysis of the primary outcome, adjusted for participating medical center. 10/4/13: Addition of the IPS-25 Fidelity Scale. The addition of the IPS-25 scale should increase the validity of study results. 1/15/15: Addition of an Interactive Voice Recognition/Web-based (IVR/Web) System; as an option for weekly data capture of the primary outcome data (employment history). 8/17/15: Approval of Supplemental Data Collection at Participant Study Exit; use of the data collected will supplement the study analysis plan and, provide further insight into the impact of vocational rehab. A Participant Satisfaction Survey will allow study participants to indicate their level of satisfaction with the study, vocational rehabilitation intervention and, suggestions for future research.
