HIV Prevention Program for African American Teen Males
HIV InfectionsSexually Transmitted InfectionsThe purpose of this study is to test if sexual health interventions can reduce the incidence of STIs among African American teens (15 to 21 years old). By doing this study, we hope to help African American teens improve their condom use skills and encourage them to use condoms more frequently. If the number of STIs in this population can be decreased, the health of African American teen males will greatly improve. We also believe that sexual partners (typically African American teen females) will also benefit.

Role of Zinc in Recurrent Acute Lower Respiratory Infections
Acute Respiratory InfectionsAcute respiratory infections (ARIs) are the most frequent illnesses globally. Despite advances in the recognition and management ARIs, these account for over 20% of all child deaths globally.Trace mineral deficiencies have long been implicated in causation and consequences of many diseases. The importance of adequate zinc intake in human health is well documented and zinc deficiency is a large public health problem, especially among children in developing countries.Various studies suggest that zinc-deficient populations are at increased risk of developing diarrhoeal diseases, respiratory tract infections and growth retardation.Among the individual interventions zinc supplementation with universal coverage ranks 5th in preventing under five mortality in India, preceded only in order by breast feeding; complementary feeding; clean delivery; Hib vaccination; and clean water, sanitation and hygiene.Numerous studies have examined the association between child mortality and zinc deficiency. A number of randomized controlled trials evaluating effect of zinc supplementation have found the intervention to be beneficial in reducing ARI and diarrhoeal mortality and morbidity but few studies have found beneficial effect in diarrhea and no or even contrasting effects on morbidity pattern of acute respiratory infections. Whereas role of zinc in diarrhea is now a well established and specific guidelines and recommendations have been given for zinc supplementation in diarrhea, role of zinc in acute respiratory infections is controversial. The contrasting effect of zinc on diarrhoea and acute lower respiratory infection as reported in several studies is a public health concern, because zinc supplementation is carried out in many nutrition rehabilitation units. Further in many of randomized control trials supplement syrups also contained other vitamins, including vitamin A, known to have effect on respiratory morbidity. Most of the trials evaluating effect of zinc on respiratory morbidity and mortality are community based and children with well known causes of recurrent acute lower respiratory infections have not been excluded from the study pool. Hence the current study was planned to bridge this gap of information and attempts to detect the role of zinc using "zinc only preparations" in reducing respiratory morbidity in children aged 6 to 59 months with recurrent acute lower respiratory infections.

Interventional Study of Mucosal and Antimicrobial Responses to Repeated Vaginal Applications of...
HIV InfectionsTopical microbicides, substances that kill microbes, are being studied to prevent sexual transmission of HIV and other disease-causing agents. In the future, topical microbicides may be applied vaginally to prevent both acquisition and transmission of HIV and other sexually transmitted infections (STIs). The purpose of this study is to assess whether there is a measurable response to daily applications of a topical microbicide, 1% tenofovir gel, in women at low risk for HIV infection.

Controlled Clinical Trial of Supplemental Oxygen for the Prevention of Post-Cesarean Infectious...
Infection; Cesarean SectionSurgical Wound Infection1 morePrevious studies have demonstrated that patients who undergo surgery while they under general anesthesia have fewer wound infections if they receive higher concentrations of oxygen but this has never been studied in women who are undergoing cesarean section. We plan to randomize women who are undergoing cesarean to receive either standard of care oxygen flow through a nasal cannula during their cesarean section only or a higher concentration of oxygen than they would typically receive through a face mask. Women will receive this therapy during their cesarean and for 2 hours afterwards. We will follow them after their surgery for evidence of infection either in their wound or their uterus.

Cardiac SurgerySternal Wound InfectionThe purpose of this study is to determine whether the gentamicin-collagen sponge is safe and effective in preventing sternal wound infections in patients undergoing cardiac surgery who are at a greater risk of developing sternal wound infections.

Study to Evaluate the Immune Response of United Kingdom (UK) Infants Receiving DTaP/Hib/IPV, Meningococcal...
Meningococcal InfectionsPneumococcal InfectionsThe purpose of this study is: To assess whether there are differences in antibody persistence eight months post primary (pre-booster) or in responses to the booster with regard to the Meningococcal C Conjugate (MCC) vaccine given in infancy. To examine levels of diphtheria and tetanus antibody pre- and post-booster, with regard to the carrier proteins contained in the conjugate vaccines.

HIV InfectionsSexually Transmitted InfectionsThis study will evaluate the effectiveness of community-level behavioral and biomedical interventions, each alone and combined, in reducing sexual risk behavior and HIV/sexually transmitted infections in Peruvian men who have sex with men.

Two Strategies for Methicillin-resistant Staphylococcus Aureus (MRSA) Infection Prevention in Surgical...
MRSA InfectionThe study is a two-arm controlled multi-centre trial of two strategies to reduce nosocomial MRSA transmission and infection among surgical patients. Enrolment and primary analyses will be performed at the hospital level. A total of ten adult surgical departments with at least 3 surgical subspecialties each will participate in the study. Sites of the study are located in 9 countries (UK, France, Spain, Germany, Switzerland, Italy, Serbia, Greece and Israel). The primary objective is to determine the effect of an early MRSA detection & decolonization & isolation strategy compared to an enhanced standard control strategy on healthcare-associated MRSA isolation rates among surgical patients at risk of MRSA carriage, who are hospitalized for at least 24 hours.
