Filter by:The purpose of this study is to evaluate the value of positron emission tomography/computed tomography in various inflammatory conditions caused by bacterial infection or vasculitis. Glucose analog FDG is sensitive to detect inflammation foci but we hypothesize that other imaging agents such as PK11195 and Ga-citrate may have added value in certain applications.
This study will assess the effectiveness of social media website devoted to vaccines to change immunization knowledge, perceptions and behavior. If effective, this intervention will represent an innovative, low cost and broadly applicable resource to reduce parental vaccination concerns. The study has two hypothesis: 1. Parents receiving usual care plus social media website will demonstrate higher early childhood immunization rates to parents receiving either usual plus non interactive website or usual care only. 2. Parents receiving usual care plus social media website will demonstrate positive changes in knowledge, attitudes and beliefs supporting vaccination compared to parents receiving either usual care plus non-interactive website or usual care only.
The purpose of this study is to compare antibiotics versus no-treatment in kidney transplant recipients with asymptomatic bacteriuria.
The objective of the present study is to analyze the overall tubular function, and in particular that from the proximal tubule and the thick ascending loop of Henle (TALH) in patients with HIV infection receiving or not tenofovir-containing antiretroviral treatment in comparison with seronegative controls, by applying a validated tubular physiological test known as "Low sodium infusion test". Hypothesis is that patients with HIV infection and normal renal function will show subclinical tubular abnormalities compared with seronegative controls
The purpose of this comparative study is to evaluate the efficacy of an ovule with triple active agents (terconazole, clindamycin and fluocinolone) versus another ovule with triple active agents (nystatin, metronidazole and fluocinolone) in the treatment of symptoms caused by the presence of vaginitis (inflammation of the vagina) or bacterial vaginosis (polymicrobial, nonspecific vaginitis associated with positive cultures of Gardnerella vaginalis and other anaerobic organisms and a decrease in lactobacilli).
The purpose of this study is to determine the extent to which bacterial growth in the nostrils by S. aureus, a common bacteria that is found in hospital environment, can be reduced by NOZIN® Nasal Sanitizer® antiseptic nasal swabs during the course of a typical 10-hour work period in participants known to have S. aureus in their nose passages.
Adolescents with mental health (MH) disorders (MHD) have higher rates of HIV/STI sexual risk behaviors than those in the general population. In Brazil, among youth seeking HIV testing, those testing positive had more MH problems than HIV-negative youth; HIV/STI sexual risk reduction is not regularly implemented within MH care for adolescents. Our NIMH-funded RCT in Rio de Janeiro (Rio; R01MH065163; PI: Wainberg) promises to provide such intervention for adults with MHD. A comparable evidence-based HIV/STI prevention intervention for adolescents is not available in Brazil; this application targets this need. Using quantitative and qualitative methods we will explore the contextual influences on sexual risk behavior of Brazilian youth ages 13-24 with MHD to inform intervention adaptation. The investigators will then pilot-test the family-based (parent-adolescent dyad) intervention HIV, STI and pregnancy prevention intervention with a sample of male and female youth age 13-24 years (n=144) with MHD who are in MH treatment in four community-based sites in preparation for the RCT.
This is a study to evaluate the efficacy and safety of three experimental drugs compared with telaprevir (a licensed product) in people with hepatitis C virus infection who have not had treatment before.
The purpose of this study is to evaluate the safety and antiviral activity of 3 direct-acting antiviral agents (DAAs; ABT-450/ritonavir/ABT-267 [ABT-450/r/ABT-267; ABT-267 also known as ombitasvir] and ABT-333 [also known as dasabuvir]) plus ribavirin (RBV) compared with telaprevir (TPV) with pegylated interferon/ribavirin (pegIFN/RBV) in patients with chronic hepatitis C virus genotype 1 (HCV GT1) infection without cirrhosis who were previously treated with pegylated interferon/ribavirin (pegIFN/RBV).
Background: - Pulmonary nontuberculous mycobacterial (PNTM) infection is caused by a common type of bacteria in the environment. Although PNTM infection is most common in people with lung diseases, it can also affect healthy people. It can be difficult to treat, and affects parts of the body other than the lungs. For example, PNTM may affect the cilia, the hair-like structures inside the nose and lungs that help move dirt and debris out of the body. - Ciliary beat frequency (CBF) is a measurement of how fast cilia move. People with PNTM infection have a lower CBF than healthy people. Nitric oxide (NO) is a gas in the body that may affect CBF. People with PNTM infection produce lower amounts of NO in their noses than healthy people. Researchers want to see if a drug called sildenafil can increase NO production and CBF. If sildenafil can improve these measurements, it may be a useful treatment for PNTM infection. Objectives: - To study the effect of sildenafil on CBF and NO levels in people with PNTM infection. Eligibility: - Individuals at least 18 years of age who have PNTM infection. - Participants must be enrolled in a related National Institutes of Health study on bacterial infections. The study is Natural History, Genetics, Phenotype and Treatment of Mycobacterial Infections. Design: - Participants will be screened with a physical exam and medical history. They will also have heart and lung function tests, as well as tests of NO production in the nose. They will provide samples of sputum and cells from inside the nose. - Before the first study visit, participants will collect sputum samples for 24 hours. They will bring the samples to the study visit. - At the first study visit, participants will have heart and lung function tests, as well as tests of NO production in the nose. They will provide blood, urine, sputum, and nasal cell samples. They will also receive sildenafil tablets to take at home. - Participants will take sildenafil tablets three times a day. - The second study visit will be 7 days after the first one. The tests from the first visit will be repeated. Participants will receive more sildenafil tablets to take on the same schedule as before. - The third and final study visit will be 30 days after the first one. The tests from the first visit will be repeated. Participants will stop taking sildenafil at this visit. - A follow-up phone call will be made about 2 weeks after the final study visit. This call will ask questions about quality of life and any symptoms or side effects of the study.
