The hepatitis B virus (HBV) is predominantly a hepatotropic virus but also infects cells of the lymphatic system. HBV genomes (DNA, messenger (m)RNA, covalently closed circular (ccc) DNA) and proteins have been found in extrahepatic sites such as peripheral blood mononuclear cells (PBMC), lymph nodes, spleen, bone marrow and cerebrospinal fluid. HBV entry into hepatocytes occurs by binding of the HBV preS1 surface protein to its specific receptor, the bile acid transporter, sodium taurocholate co-transporting polypeptide (NTCP)...

Dear Editor, Proper and consistent use of male condoms can be a highly effective method of preventing the transmission of sexually transmitted infections (STIs) and HIV (1), but this method relies on men's willingness and ability to use condoms. In the United States of America, about 20% overall and less than 50% of adults with multiple partners used a condom at last intercourse (2). In Serbia in 2013 (3), 50.0% of women and 62.5% of men aged 15-49 who had more than one partner in the past year used a condom during their last intercourse...

The hepatitis B virus (HBV) is a global problem; however, the burden of HBV infection in pregnant women in Botswana is unknown. We sought to determine the prevalence of chronic and occult HBV infection in human immunodeficiency virus (HIV)-infected and -uninfected pregnant women in Botswana. Samples from 752 pregnant women were tested for hepatitis B surface antigen (HBsAg), and HBsAg-positive samples were tested for hepatitis B e antigen (HBeAg) and HBV DNA load. Samples that were HBsAg negative were screened for occult HBV infection by determining the HBV DNA load...

Among 230,360 women with diagnosed HIV in the United States (U.S.), ~ 8,500 give birth annually, and unplanned pregnancies (as with HIV-negative women) are prevalent. However, unplanned pregnancies and contraceptive use among HIV-positive women have been understudied. To examine unplanned pregnancies and contraceptive use among HIV-positive women, we used 2013-2014 data from the Medical Monitoring Project (MMP), an HIV surveillance system that produces national estimates for HIV-positive adults in care in the U...

BACKGROUND: Water immersion during labour and birth is increasingly popular and is becoming widely accepted across many countries, and particularly in midwifery-led care settings. However, there are concerns around neonatal water inhalation, increased requirement for admission to neonatal intensive care unit (NICU), maternal and/or neonatal infection, and obstetric anal sphincter injuries (OASIS). This is an update of a review last published in 2011. OBJECTIVES: To assess the effects of water immersion during labour and/or birth (first, second and third stage of labour) on women and their infants...

BACKGROUND: Some HIV sero-discordant couples are faced with the dual challenge of preventing HIV transmission to the uninfected partner and avoiding unintended pregnancy. Therefore, we hypothesized that sero-discordance is associated with dual method use at last sex. METHODS: We analyzed data from a cross-sectional survey of HIV-infected men and women attending 2 ART clinics in Lilongwe, Malawi. We used Fisher's exact test and Wilcoxon rank sum to assess for associations between sero-discordance, covariates, and dual method use...

BACKGROUND: Global guidelines recommend pre-exposure prophylaxis (PrEP) use by women at risk for HIV, including during pregnancy, a period with heightened HIV risk. However, data to support safety of PrEP use during pregnancy are limited, particularly from women using PrEP throughout pregnancy. METHODS: In an open-label delivery study of PrEP integrated with ART for high risk HIV serodiscordant couples in Kenya and Uganda (the Partners Demonstration Project), women who became pregnant while using PrEP were offered the option to continue PrEP throughout pregnancy...

Atazanavir/ritonavir concentrations change over pregnancy in HIV-positive patients; the impact of genetic variants is unknown. 20 patients were enrolled: antiretrovirals' plasma and intracellular concentrations were measured in addition to single nucleotide polymorphisms in transport affecting genes. Linear logistic regression showed that genetic variants in organic-anion-transporter-1B1 and pregnane-X-receptor encoding genes affected third trimester atazanavir exposure. In this prospective study genetic variants partially explained the observed inter-patient variability in third-trimester antiretrovirals' exposure...

HIV-positive children are still born in Europe despite low mother-to-child transmission (MTCT) rates. We aimed to clarify the remaining barriers to the prevention of MTCT. By combining the national registers, we identified all women living with HIV delivering at least one child during 1983-2013. Of the 212 women delivering after HIV diagnosis, 46% were diagnosed during the pregnancy. In multivariate analysis, age >30 years (P = 0.001), sexual transmission (P = 0.012), living outside of the metropolitan area (P = 0...

In developing countries, up to 20% of maternal deaths during pregnancy are due to suicide, and being HIV-infected confers additional risk. This manuscript sought to identify perinatal correlates of suicidal ideation among women living with HIV (WLHIV) in rural South Africa. Pregnant WLHIV (N = 681) were recruited and re-assessed at 12-months postpartum. Mean age was 28.3 (SD = 5.7) years and 68% were below the poverty line. Prenatal suicidal ideation was 39%; suicidal ideation continued for 7% at 12 months, 13% experienced incident suicidal ideation, and for 19% suicidal ideation had stopped postnatally...

A 39-year-old HIV-positive black African woman with previously treated cerebral toxoplasmosis experienced a foetal intra-uterine death due to congenital toxoplasmosis. This case demonstrates the complexities of screening for maternal toxoplasmosis in the context of pregnancy and HIV infection-related cell-mediated immunosuppression. Additionally, the case highlights the challenges in providing effective preventative and therapeutic drug options for congenital toxoplasmosis.

The Appalachian region of the United States is experiencing a large increase in hepatitis C virus (HCV) infections related to injection drug use (IDU) (1). Syringe services programs (SSPs) providing sufficient access to safe injection equipment can reduce hepatitis C transmission by 56%; combined SSPs and medication-assisted treatment can reduce transmission by 74% (2). However, access to SSPs has been limited in the United States, especially in rural areas and southern and midwestern states (3). This report describes the expansion of SSPs in Kentucky, North Carolina, and West Virginia during 2013-August 1, 2017...
