NCT03501966
Randomized trial of adults (≥18 years old) with idiopathic intracranial hypertension and moderate to severe visual loss without substantial recent treatment who are randomly assigned to (1) medical therapy, (2) medical therapy plus ONSF, or (3) medical therapy plus VPS. The primary outcome is visual field mean deviation change at first of Month 6 (26 weeks) or time of treatment failure of the eligible eye(s), followed by a continuation study to assess time to treatment failure. The determination of eligible eye(s) is based on meeting the eligibility criteria at baseline.
NCT00002874
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Androgens can stimulate the growth of prostate cancer cells. Hormone therapy using bicalutamide may fight prostate cancer by reducing the production of androgens. It is not yet known if radiation therapy is more effective with or without bicalutamide for prostate cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without bicalutamide in treating patients who have stage II or stage III prostate cancer and elevated prostate-specific antigen (PSA) levels following radical prostatectomy.
NCT03663335
The purpose of this study is to investigate the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of three CFZ533 dose regimens in kidney transplant recipients. This study will allow assessment of the ability of CFZ533 to replace Calcineurin inhibitors (CNIs) in terms of anti-rejection efficacy, while providing better renal function with a better safety and tolerability profile. Results of this study will be used to inform the CFZ533 dose and regimen selection for investigation in later phases of clinical development.
NCT02777177
Bariatric surgery is a powerful tool for producing significant and durable weight loss. Yet, not all patients achieve initial weight loss success and many patients have weight regain as early as 1-2 years post-surgery. Suboptimal weight loss patterns not fully explained by surgical, demographic, and medical factors has led to greater emphasis on patient behaviors evidenced by clinical guidelines that focus on appropriate eating and physical activity. However, research to inform such guidelines typically has relied on imprecise measures or not been specific to bariatric surgery. There is also little understanding of mechanisms by which psychosocial factors influence outcomes. Thus, there is a need to: (a) measure behaviors and psychosocial factors thought to be related to surgical outcomes (particularly those emphasized in guidelines) using innovative strategies to maximize data quality, (b) determine which behaviors and psychosocial factors are related to outcomes, and (c) explore how psychosocial factors influence weight both directly and via influences on behavior. Our research team was the first to employ innovative mobile health (mHealth) technology within an Ecological Momentary Assessment (EMA) framework to measure adherence to recommended behaviors at 6 months post-surgery. The investigators propose to build on this work by using EMA to measure behavioral, psychosocial, and environmental factors over a longer period to understand how they predict success and risk after surgery. An NIH-funded multi-sensor PiLR HEALTH platform will integrate objective sensor data measuring behaviors and the environments in which they are performed with self-report information collected via smartphone in real-time and in patients' natural environment. Participants (N=100) recruited from 2 ASMBS-designated centers of excellence will complete a 10-day EMA protocol pre-surgery and at 3, 6, and 12 months post-surgery to assess recommended behaviors \[e.g., meal frequency, PA\], psychosocial indicators with the most prior evidence of an association with surgical outcomes (e.g., mood/depression), and key environmental factors (e.g., type/quality of the food environment). Participants will also be weighed at the above time points. Along with describing patterns in behaviors and their relation to weight loss, the investigators will test causal models to understand how complex systems of behavioral, psychosocial, and environmental factors affect weight loss, and to identify optimal targets for intervention. This project has the potential to build a much more sophisticated and valid understanding of who is and is not successful after bariatric surgery and why. This new understanding will directly contribute to improved (i.e., specific, consistent, and validated) guidelines for recommended pre and postoperative behaviors, which could lead to improved surgical outcomes. The enhanced understanding will also inform behavioral, psychosocial, and environmental targets for intervention that are mostly likely to improve surgical outcomes.
NCT01434290
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Given radiation therapy in different ways may kill more tumor cells. PURPOSE: This randomized phase II trial studies radiation therapy to see how well it works in treating patients with prostate cancer.

NCT03630770
This study evaluates whether adding a dietary supplement similar to coconut oil (MCT oil) to feedings in premature infants will reduce the amount of yeast (Candida) detectable in their stool. Infants who have Candida in their stool are eligible to participate. Half of the enrolled infants will have additional MCT oil added to their feedings and half will not.
NCT02625610
The purpose of this study was to demonstrate superiority of treatment with avelumab versus continuation of first-line chemotherapy.
NCT00777491
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy may kill more tumor cells. PURPOSE: This randomized phase II trial is studying two different chemotherapy and radiation therapy regimens to see how they work in treating patients with stage II or stage III bladder cancer that was removed by surgery.

NCT01563575
The project's background is the notion that patient centred clinical health promotion has been shown to significantly improve both outcomes and patient safety. Accordingly, the WHO describes health promotion as a key dimension of quality in hospitals, and the organization has developed standards on the topic in order to help hospital management and staff members to assess and improve the quality of health care and thereby achieve better health for patients, staff, and community. Even so, however, health promotion is still a very implicit part of nearly all quality standards on hospitals. Moreover, assessing hospitals departments' health promotion performance is still quite an unexplored area. On this basis, this project will test a new recognition process that uses the relevant WHO-HPH tools and standards to assess performance, by way of explicit documentation and evaluation of clinical health promotion activity. The project is deigned as a RCT, with a control group that undergoes the recognition process immediately and a control group that continue usual clinical routine. Then, after one year, the control group also begins the recognition process (= delayed start), while the Intervention group (=immediate-start) continues with the recognition process. Doing this allows for a great array of measurements, and hopefully the project will then show whether the recognition process really benefits implementation of health promotion in hospitals and health services, and also, if this really generates better health gains for patients and staff. The outcome measurements will be frequency of health promotion services delivered on smoking, excessive alcohol use, overweight, malnutrition, and physical activity to patients in need. Such services could for instance be motivational counselling and brief interventions, as well as intervention, rehabilitation and after treatment. Physical, mental, and social health status among patients and staff will be measured by short form (SF36).
NCT03219164

NCT03540069
This research project will investigate the determinants of cervical cancer screening uptake and sustained utilization in this region and develop and evaluate a context-specific peer education behavioral intervention to improve uptake. Research supports the effectiveness of peer education in increasing cancer screening rates but, currently, no cervical cancer screening peer education program specific to rural Senegal exists. To inform the participatory development of this program, the investigators will assess barriers and facilitators of screening at multiple levels: individuals (women aged 30 to 59), households (family or principle social unit of at-risk women), and the community (immediate village or neighborhood with common amenities of at-risk women). We hypothesize that a peer education program that adapts to changing contexts over time and is targeted at a multi-level audience will result in early, widespread uptake and sustained use of the VIA cervical cancer screening program. Study findings will inform programmatic planning in Kedougou and the peer education curriculum we develop can serve as a template for maximizing early impact of new cervical cancer screening services implemented in other areas of rural Senegal. Our long-term goal is to inform national-level policy to guide the implementation of cervical cancer screening programs in other rural Senegal regions.
