BACKGROUND Although antibiotic prophylaxis for infective endocarditis (IE) has been recommended for persons with predisposing cardiac conditions (PCCs) for many years, its efficacy, which has not been demonstrated, has been recently challenged. To assess its usefulness, we estimated the risk of developing IE after undergoing a dental procedure for which subjects would be eligible for prophylaxi...

Bacterial endocarditis is an infection of the endothelial surface of the heart, including heart valves and is potentially life threatening. Antibiotic prophylaxis is indicated prior to invasive procedures in patients with certain high-risk cardiac conditions and thorough history needs to be elicited prior to performing such procedures. Herein, we present a case of splenorenal infarction seconda...

BACKGROUND Dissemination of research results to study participants and stakeholders and provision of proven effective products in the immediate post-trial period are core elements of the conduct of biomedical HIV prevention clinical trials. Few biomedical HIV prevention trials have demonstrated HIV protection with novel interventions, and thus, communication of positive trial results and provis...

We evaluated the efficacies of oral prophylactic treatment with amoxicillin (AMX), clindamycin (CLI), and moxifloxacin (MXF) in the prevention of bacteremia following dental extractions (BDE). Two hundred twenty-one adults who required dental extractions under general anesthesia were randomly assigned to a control group, an AMX group, a CLI group, and an MXF group (the individuals in the drug t...

BACKGROUND Common dental procedures induce bacteremia. To prevent infectious complications from bacteremia in patients with specific medical conditions, antibiotic prophylaxis is considered. Recommendations are often unclear and ambiguous. In a previous study we reported wide variations in general dental practitioners' (GDPs') administrations of antibiotic prophylaxis. We hypothesized that with...

The most recent revision of the American Heart Association guidelines on infective endocarditis prophylaxis occurred in 2007. These revisions were based on the fact that current data have brought into question the benefit of previous recommendations for infective endocarditis prophylaxis. It was noted that the bacteremia that occurs following dental procedures represents only a fraction of the ...

Preexposure prophylaxis (PrEP) is a highly effective HIV prevention method; however, it is underutilized among women who are at risk for acquisition of HIV. Women comprise one in five HIV diagnoses in the United States, and significant racial disparities in new HIV diagnoses persist. The rate of new HIV diagnoses among black and African American women in 2015 was 16 times greater than that of w...

Purpose of review Preexposure prophylaxis (PrEP) with daily Truvada has demonstrated clinical efficacy against HIV-1 acquisition that correlates with high adherence. Long-acting antiretroviral drugs offer an alternative to daily regimens and may improve PrEP adherence. This review summarizes the preclinical nonhuman primate studies for evaluating the efficacy of cabotegravir long-acting as PrEP...
