Filter by:Recently there was described an increase in left ventricular mass after kidney donation. It is uncertain whether this is reversible or not. Allopurinol lowers uric acid in the blood and is normally indicated for gout, but studies have showed that it also can reduce the thickness of the left ventricle of the heart in people with heart- and kidney disease. The investigators wish to give allopurinol or placebo to kidney donors based on randomization and investigate if this has the same effect on kidney donors. The investigators are assessing this by performing a cardiac MRI at baseline and after 9 months of treatment. In addition the investigators wish to see if allopurinol can have beneficial effects on blood pressure and insulin sensitivity as well.
Background: Despite similar treatment outcomes for surgery or conservative care, the number of surgeries for the care of rotator cuff (RTC) related shoulder pain has increased. With the increase in surgery, there is an increased risk of harms, increased costs, and high re-tear rates. Patient expectations are beliefs or attitudes that include pre-treatment thoughts and beliefs regarding the need for specific treatment methods and the timing and intensity of these methods. Brief interventions designed to alter and enhance treatment expectations for conservative care and have been shown to improve patient expectations, but to date, no studies have explored whether such interventions can influence patient decisions to pursue surgical care. The investigators propose a comprehensive intervention that involves Patient Engagement Education, and Restructuring of Cognitions (PEERC) that is designed to change expectations, will reduce the likelihood that patients will choose to have shoulder surgery and improve functional outcomes. The cognitive behavioral therapy (CBT) approaches that form the core of our PEERC protocol are patient-centered and are designed to empower the patient in their own recovery process. Purpose/Aims: To examine the effect of the PEERC protocol on the decision to have surgery (primary), and improve global well-being, pain catastrophizing, pain, functional outcomes, and follow up expectations (secondary).
Household air pollution (HAP) is a top-priority public health problem in developing countries. According to the most recent comparative risk assessment, 3.5 million people die prematurely each year as a result of HAP exposures. While uncertainties remain regarding causal links between HAP exposures and health, the time is ripe for focused research into effective interventions. Limited past research has shown that the demand for clean cookstoves is low, and that households continue to use traditional hearths even when they have clean stoves. The investigators propose to harness an existing cohort in Ghana to study factors that increase the adoption of clean cookstoves, and to test strategies to promote adoption and continued use.
The purpose of this study is to evaluate theColovac device, a single use, temporary intraluminal bypass device,intended to reduce contact of fecal content with an anastomotic site, following colorectal surgery (open or laparoscopic).
African Americans have considerably higher rates of HIV infections than do White, Hispanic, Asian, and Native Americans. African Americans accounted for 59% of all diagnoses of HIV infection among youth (13-24 years of age) in the United States. Young African Americans also have disproportionately high rates of other sexually transmitted infections (STIs). Therefore, the broad, long-term objective of this research is to identify interventions to reduce the risk of HIV and other STIs among young African Americans. Entertainment-education refers to narrative interventions designed to change behavior while providing entertainment. Several studies have evaluated the impact of media content on HIV risk behavior. One study found that exposure to an entertainment-education based HIV testing campaign was associated with increases in HIV testing among sexually active teens 12 months post exposure. Similarly, a radio soap opera called "Twende na Wakati" became the most popular television show in Tanzania and was highly successful in reducing the number of sexual partners and increasing condom use. A narrative video intervention study in STI clinic waiting rooms in three U.S. cities found a significant reduction in STI re-infection among patients visiting during months when the video was shown compared with patients visiting during months when it was not shown. Although these studies show that entertainment-education can be a promising medium for behavior change, none of them evaluated the efficacy of a tailored online entertainment-education intervention specifically designed for African American youth. To address this gap in the literature, this study tested the preliminary efficacy of an innovative, theory-based HIV risk-reduction serial drama intervention, Reality Check, specifically tailored to young African Americans. We used a randomized controlled trial, allocating African Americans 18 to 24 years of age to Reality Check, or an attention-control intervention promoting physical activity. Each intervention was delivered as a series of videos streamed online and accessible via any Internet-capable device. Participants completed surveys online at baseline, immediately post intervention, and 3 months post intervention. We hypothesized that, Reality Check would reduce condomless sex during the 3-month post-intervention period compared with the attention-matched control group, adjusting for baseline of the criterion.
This was a single center, open-label, single-arm study in which approximately 28 Hepatitis A virus (HAV)-seronegative healthy subjects were enrolled. There was a screening period of up to 28 days during which subjects were screened for enrollment in the study. Healthy subjects received a single intramuscular (IM) dose of GamaSTAN (0.2 mL/kg), followed by a pharmacokinetic (PK) sampling period of 150 days (approximately 5 half-lives). The protective levels of anti-HAV antibodies were assessed up to 60 days after the administration of GamaSTAN. A PK curve was obtained during the PK sampling period.
To prospectively assess the mechanical ventilation management when its provided by Emergency Physicians in French Hospital, and to assess complications and outcome of these patients. The study could be measure the proportion of patients developing an Acute Respiratory Failure Distress after a take care of by French Emergency Departments.
This study evaluates the impact of a solar lighting system on kerosene lamp use, levels of indoor air pollution, and health in women living in rural Uganda. Half of the participants will receive the lighting systems immediately, while the other half will receive them after an 18 month delay.
Lung cancer is the most common cancer in the world and the leading cause of cancer-related deaths in Western countries. Unfortunately, at the time of diagnosis, the majority of patients already have metastatic disease and a systemic, palliative treatment is the primary therapeutic option. Guidelines for PS 2 patients or older than 75 years old patients at the time of diagnosis recommend for fit patients a carboplatin doublet chemotherapy. Nivolumab has proven efficacy in 3rd line squamous cell lung carcinoma and is superior to chemotherapy in 2nd line treatment of squamous and non-squamous lung cancer in term of overall survival. In 1st line, nivolumab failed to show superiority compared to a platin based doublet in terms of progression free survival and overall survival in tumors ≥ 5% PD-L1 expression. The association Nivolumab plus Ipilimumab showed encouraging results in first line setting in phase 1 study. The investigators think that with regard to the manageable toxicity of nivolumab in lung cancer population and the possibility to obtain long responses, this association could be a valid option for this population of elderly and/or PS2 patients in term of overall survival.
