Kinetics of RPR Decline in Pregnant Persons Treated for Syphilis in Pregnancy and Their Infants.

Congenital syphilis is a re-emerging infectious threat in areas of North America. The purpose of this study was to quantitatively describe the rate of decline of nontreponemal (rapid plasma reagin, RPR) titers in pregnant persons with syphilis and their infants. In a retrospective review, we included 120 pregnant persons with 563 reactive RPR measurements (median 5, range 2 to 11 per person) and 35 infants with 81 RPR measurements (median 2, range 2 to 6 per infant).

A phase 1 randomized controlled trial of a peptide-based group A streptococcal vaccine in healthy volunteers.

Background: Group A streptococci (Strep A) orStreptococcus pyogenes is a major human pathogen causing an estimated 500,000 deaths worldwide each year. Disease can range from mild pharyngitis to more severe infections, such as necrotizing fasciitis, septicemia, and toxic shock syndrome. Untreated, Strep A infection can lead to the serious post streptococcal pathologies of rheumatic fever/rheumatic heart disease and post-streptococcal glomerulonephritis.

Advances in the Critical Care of Ischemic Brain Infarction.

Acute care for ischemic stroke has dramatically evolved over the last years. Cerebral reperfusion is possible up to 24 h after symptoms onset. Advanced brain imaging allows identifying salvageable ischemic brain tissue, and the development of newer endovascular devices permits access to distal vessels.

Life's Essential 8 and Poor Brain Health Outcomes in Middle-Aged Adults.

Background And Objectives: Mounting evidence points to a strong connection between cardiovascular risk during middle age and brain health later in life. The American Heart Association's Life's Essential 8 (LE8) constitutes a research and public health construct capturing key determinants of cardiovascular health. However, the overall effect of the LE8 on global, clinically relevant metrics of brain health is still unknown.
