NCT01945866
Although anti-vascular endothelial growth factor (VEGF) therapy is generally effective as treatment for center-involved diabetic macular edema (DME), a substantial proportion of anti-VEGF-treated eyes with DME do not achieve vision of 20/20 or complete resolution of retinal thickening. Indeed, over 50% of ranibizumab-treated eyes did not achieve a 2 or more line improvement in visual acuity from baseline at 2 years in Protocol I, a previous DRCR.net (Diabetic Retinopathy Clinical Research Network) study. Furthermore, 27% of ranibizumab-treated eyes still had central subfield (CSF) thickness on time-domain optical coherence tomography (OCT) ≥ 300 at 1 year, and more than 40% of ranibizumab-treated eyes did not achieve complete resolution of retinal thickening (\< 250 microns) by 2 years. Thus, there is a need for alternative or additional treatments that will improve vision by reducing retinal edema in eyes with persistent DME following previous anti-VEGF therapy. Intravitreal steroid is not as efficacious as ranibizumab in eyes with DME overall, but it has been shown to have a positive effect for DME in some eyes and might add benefit in eyes that are already receiving anti-VEGF. The main objective of this study is to assess the short-term effects of combination steroid+anti-VEGF therapy on visual acuity and retinal thickness on OCT in comparison with that of continued anti-VEGF therapy alone in eyes with persistent central-involved DME and visual acuity impairment despite previous anti-VEGF treatment. This study will provide important information for the design of a future confirmatory phase III clinical trial on the efficacy of combination steroid and anti-VEGF in eyes with persistent DME and vision impairment following previous anti-VEGF therapy. The primary outcome for efficacy will be the mean change in visual acuity at 24 weeks. Each study eye is required to complete a 12-week run-in phase. The run-in phase will identify study eyes that truly have persistent DME despite anti-VEGF therapy by requiring an additional 3 injections while also collecting standardized visual acuity and OCT measurements. At the enrollment, 4-week and 8-week visits of the run-in phase, enrolled eyes will receive an intravitreal injection of ranibizumab 3mg. Then at the 12-week run-in visit, if the eye still has persistent DME, it will be randomized to receive either intravitreal sham+intravitreal ranibizumab 0.3 or intravitreal dexamethasone+intravitreal ranibizumab 0.3 injections. The randomized study duration is 24 week, during which a protocol visit takes place every month. The combination injections of sham+ranibizumab or dexamethasone +ranibizumab will be given at the randomization visit (baseline) and at the 12-week visit after randomization. In between, an intravitreal injection of ranibizumab only will be given to study eyes at the 4, 8, 16 and 20 week visits.

NCT03590795
Sleep is an important contributing factor to people's health. However, over one third of the general population has sleep complaints, causing both health related problems, and economic impact. Many do not think their problem sleep is serious enough to consult a physician (primary care or sleep specialist). For a selection of this population, self-tracking devices can be a solution, but these trackers are often activity based and therefore lacking in their capacity to give insight into underlying causes of poor quality sleep and daytime fatigue. A new options for these confused sleeper is an online questionnaire, developed by Philips and Cooperative Research Center (CRC) for Alertness, Safety and Productivity Imagine a troubled sleeper awake at 3 am, they search "Why can't I sleep?" and find the survey. From there the user takes the sleep survey, which has the ability to assess their most likely sleep problem or problems from a list of seven sleep problem categories based upon their responses. At the end of the survey, participants will get information about which problem category they will fall into, and the level of certainty around that. The purpose of the study is to determine the accuracy of the questionnaire in identifying the correct sleep problem when compared with the assessment of a sleep physician in a clinical sleep center. We hope to enroll 200 participants which was based upon an Initial power analyses were completed using pilot data, assuming accuracy rates of 70, 80, and 90% and a total sample size of 200. The intervals would be about ± 4.5% (for 90%) to ± 7% (for 70%). Participants will complete the survey, be blinded to the results, and then have a consultation with a sleep physician who will make an independent assessment.
NCT00053898
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Tamoxifen may fight breast cancer by blocking the use of estrogen. Anastrozole may fight breast cancer by decreasing estrogen production. It is not yet known whether anastrozole is more effective than tamoxifen in preventing the recurrence of breast cancer. PURPOSE: This randomized phase III trial is studying anastrozole to see how well it works compared to tamoxifen in preventing the recurrence of breast cancer in postmenopausal women with ductal carcinoma in situ who are undergoing lumpectomy and radiation therapy.

NCT00433381
This randomized phase II trial is studying the side effects and how well giving bevacizumab together with irinotecan or temozolomide works in treating patients with recurrent or refractory glioblastoma multiforme or gliosarcoma. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as irinotecan and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bevacizumab together with irinotecan or temozolomide may kill more tumor cells.

NCT00683306
The purpose of this study is to provide gefitinib treatment to patients who, on completion or closure of other gefitinib clinical studies, were either receiving placebo treatment, or are continuing on the same dose and regimen of gefitinib established in their preceding study, for as long as the patients continue to derive benefit.
NCT02425111
The purpose of this study is to evaluate endoscopic remission at Week 26 as assessed by ileocolonoscopy.
NCT03026322
Complications are common during endotracheal intubation of critically ill adults. Manual ventilation between induction and intubation ("bag-valve-mask" ventilation) has been proposed as a means of preventing hypoxemia, the most common complication of intubation outside the operating room. Safety and efficacy data, however, are lacking. PreVent is a randomized trial comparing manual ventilation between induction and laryngoscopy to no manual ventilation between induction an laryngoscopy during endotracheal intubation of critically ill adults. The primary efficacy endpoint will be the lowest arterial oxygen saturation. The primary safety endpoints will be the lowest oxygen saturation, highest fraction of inspired oxygen, and highest positive end-expiratory pressure in the 24 hours after the procedure.
NCT02135614
