Filter by:This pilot study will explore the usefulness of a series of questions asking about views of research from the perspective of minority and economically disadvantaged research participants. Racial and ethnic minorities are consistently under-represented in clinical research. This under-representation has been attributed primarily to an unwillingness to participate in research because of mistrust in the research establishment, especially in light of widely known historical examples of abuse. However, more recent data suggests that not being invited to participate in research, or stringent entry criteria, may contribute substantially to the low numbers of ethnic minority research participants. The perspectives of racial and ethnic minorities who are knowledgeable about or participating in research are important to understanding the kinds of vulnerabilities that exist and any important barriers to participation. People 18 years of age and older from the Cardozo clinic in Washington, D.C., who are enrolled in the National Institute of Arthritis and Metabolic Studies' natural history study are eligible to participate in this protocol. Participants are interviewed with questions about their own experiences in clinical research as well as some hypothetical research studies. Questions include participants' general views of clinical research, perceived risks and benefits of research, alternatives to research participation, the limits of what they would be willing to accept in research and types of research or research procedures they might perceive as unfair.
Evaluate the effectiveness and acceptability of care given by nurse specialists in out patient clinics, through a randomized controlled study.
Studies in humans and animals support that stress and/or elevations in corticosteroids lead to changes in hippocampal structure and functioning. This is important as patients with major depression frequently have elevated cortisol, and millions of patients receive prescription corticosteroids (e.g. prednisone). Both depression and corticosteroid therapy are associated with memory impairment and hippocampal atrophy. Our research uses corticosteroid-treated patients to explore interventions that might protect the brain from the effects of stress or corticosteroids. We propose to give 30 corticosteroid-treated asthma patients acetaminophen or placebo. Between group differences in mood, memory and other neurocognitive measures will serve as outcome measures.

A bacterium called Group A Steptoccoccus or "strep" is commonly found in the nose and throat of healthy adults and children and can cause a variety of illnesses. If this bacterium infects another part of the body one or more times, children may get Rheumatic heart disease (RHD). The purpose of this community based study is to see how many children between 5-15 years of age have RHD in Leon, Nicaragua. The study will also help to determine if the usual methods of detecting this disease are working. Researchers hope that this study will help to develop vaccines that may prevent "strep" infections to Nicaragua and other parts of the world. About 3,600 children will take part in the study. The children will participate for a minimum of 1 day and have a 6 month follow-up visit if they are identified as possible or probable RHD cases. Study procedures will include clinical exams and echocardiograms to determine the presence of RHD.
The current study was designed to determine whether the HLA-DRB1, DQA1, DQB1 alleles are associated with the risk and the pattern of valve damage of RHD.
Intraarticular application of opioids versus glucocorticosteroids versus placebo in knee arthritis study goals: assessment of effectiveness and tolerability of locally applied morphine, dexamethasone or placebo in knee arthritis
This post-market clinical follow-up study was designed to compare hip replacement outcomes of the European Hip against 3 controls (Omniflex, Zweymuller, and Spotorno), however Omniflex did not end up being used. The first patient had surgery on February 18, 2000 and the final patient had surgery on September 2, 2005. There were 317 subjects consented but only 301 had hip replacement surgery (subjects received: 220 European hips, 33 Zweymuller, and 48 Spotorno). The study took place at three sites. Each site used their standard device as the control. The Austrian site enrolled 69 European hips and 33 Zweymuller hips. 92 European hips and 48 Spotorno hips were enrolled in Germany. Finally, the site in Italy enrolled 59 European hips. Although the study protocol intended collecting DEXA and RSA outcomes, the data collected by the sites did not include these outcomes.
The purpose of this study is to compare the performance and compare the wear characteristics of two polyethylene cup liners, Marathon™ and Enduron™, in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be randomly allocated to one of the polyethylene cup liners, Marathon™ or Enduron™ and will be evaluated at regular intervals using clinical and x-ray assessments.
The purpose of this study is to monitor the performance of the Pinnacle™ Cup with a polyethylene-on-metal bearing combination in the treatment of patients with hip joint disease requiring a total hip replacement. Patients who enter the study will be evaluated at regular intervals following hip surgery using patient, clinical and x-ray assessments.
