Objective: To evaluate risk factors and outcomes of syphilis during pregnancy.
Design: Hospital based, cross sectional study.
Setting: Harare Maternity Hospital, Harare, Zimbabwe.
Subjects: A random sample of 2 969 pregnant women.
Main Outcome Measures: Syphilis seroprevalence.
Results: Of the 2 969 women who provided blood samples, 4.8% were RPR positive. Approximately 2.2% of study subjects were RPR positive and TPHA negative. Notably, 2.5% of the population was RPR and TPHA positive at the time of giving birth. Older women had a higher risk of having positive syphilis status (p = 0.057). Increases in parity and gravidity were significantly associated with increased risk of syphilis infection. Prior stillbirths were associated with an increased risk of syphilis infection (odds ratio [OR], 3.4; 95% CI, 1.61 to 7.37; p = 0.001). Syphilis positive mothers were significantly more likely to give birth to syphilis positive newborns (p < 0.0001).
Conclusions: Our results suggest that there should be more effective antenatal screening and treatment of syphilis in Harare. Syphilis affects many sub-Saharan countries where effective educational outreach, screening, and treatment should take place to prevent the transmission of this venereal disease, especially among reproductive age and pregnant women.

Background: Nonenveloped viruses, such as hepatitis A virus (HAV) and parvovirus B19 (B19V), are not inactivated by detergents and solvents commonly used to manufacture plasma derivatives. Cases of transfusion-transmitted HAV and B19V have already been described in several countries. This study aimed to determine the incidence of HAV and B19V asymptomatic infections in blood donors from Rio de Janeiro and evaluate the residual risk of transmission to blood derivative recipients.

The incidence of syphilis has increased steadily over the past 25 years. Undiagnosed cases have presumably increased in the same proportions, and rare complications are at particularly high risk of being unrecognised. A previously healthy 60-year-old man presented with rapidly progressive heart failure and severe aortic and mitral valve insufficiency, with direct valvular destruction and preservation of the aortic valve annulus and aortic root.

Background: In recent years, HIV self-testing (HIVST) has emerged as a promising approach to enhance accessibility and uptake of HIV testing, particularly among populations at high risk for sexually transmitted infections (STIs). Despite its potential benefits, the effectiveness, and challenges of HIVST warrant careful examination to inform public health strategies effectively. This study investigates the effectiveness and challenges of HIV self-testing (HIVST) in populations at high risk for sexually transmitted infections (STIs).

Routine preventive care (RPC) services are recommended for people with HIV, who have higher risk of certain preventable conditions. We used a pooled cross-section of patient-years to examine receipt of 5 annual RPC services among Medicaid enrollees in the US South. Data were person-level administrative claims (Medicaid Analytic eXtract, 2008-2012) and county-level characteristics for 16 Southern states plus District of Columbia.

Consider prescribing doxycycline as prophylaxis for bacterial sexually transmitted infections (STIs) in certain clinical scenarios. New data suggests that a one-time dose of 200 mg doxycycline taken within 72 hours of an unprotected sexual encounter may reduce transmission of syphilis, gonorrhea and chlamydia by a combined two thirds in a high-risk population.
