RESUMEN

Intimate partner violence (IPV) has been highlighted as one of the challenges to the effectiveness of the Prevention of Mother-to-Child Transmission of HIV (PMTCT) programs in rural areas in South Africa. This study aimed at assessing the prevalence of prenatal and postnatal physical as well as psychological IPV, and corresponding time-invariant and time-varying predictors, among HIV-positive women attending PMTCT services in rural South Africa. The Conflict Tactics Scale (CTS) was used to assess IPV at four time points prenatal and postnatal. This study highlighted high levels of physical and psychological IPV experienced by HIV-infected women during pregnancy and in the first year after childbirth. Time-invariant predictors and time-varying predictors of physical IPV and psychological IPV were individual, social, and behavioral factors. Multi-dimensional evidence-based interventions are needed to deal with the high levels of prenatal and postnatal physical as well as psychological IPV experienced by these women.

RESUMEN

BACKGROUND: We evaluate the impact a multicomponent, behavioural, prevention of mother to child transmission (PMTCT), cluster randomised controlled trial on HIV stigma reduction among perinatal HIV infected women in rural South Africa. METHODS: In a cluster randomised controlled trial, twelve community health centres (CHCs) in Mpumalanga Province, South Africa, were randomised; pregnant women living with HIV enrolled received either: A Standard Care (SC) condition plus time-equivalent attention-control on disease prevention (SC; 6 CHCs; n =357), or an Enhanced Intervention (EI) condition of SC PMTCT plus the 'Protect Your Family' intervention (EI; 6 CHCs; n =342). HIV-infected pregnant women in the SC attended four antenatal and two postnatal video sessions; those in the EI, four antenatal and two postnatal group PMTCT sessions, including stigma reduction, led by trained lay health workers. Maternal PMTCT, HIV knowledge and HIV related stigma were assessed. The impact of the EI was ascertained on stigma reduction (baseline, 12 months postnatally). A series of logistic regression and latent growth curve models were developed to test the impact of the intervention. RESULTS: In all, 699 women living with HIV were recruited during pregnancy (8-24 weeks), and assessments were completed prenatally at baseline and at 12 months (59.5%) postnatally. Baseline scores of overall HIV related stigma and the four scale factors (personalised stigma, disclosure concerns, negative self-image, and concern public attitudes) decreased at follow-up in the intervention group, while baseline scores of overall stigma and three scale factors (personalised stigma, negative self-image, and concern public attitudes) increased at follow-up in the control group. Using longitudinal analyses, Model 1, which included time-invariant predictors of stigma assessed over the two time periods of baseline and 12 months, increases in stigma from baseline to 12 months were associated with being unemployed, having been diagnosed with HIV before the current pregnancy, and alcohol use. In Model 2, which included time-varying predictors, lower stigma scores were associated with participation in the intervention, greater male partner involvement, and consistent condom use. CONCLUSION: The enhanced PMTCT intervention, including stigma reduction, administered by trained lay health workers had a significant effect on the reduction of HIV related stigma. TRIAL REGISTRATION: clinicaltrials.gov: number NCT02085356.

RESUMEN

PURPOSE OF REVIEW: While mosquitoes have been primarily responsible for outbreaks of Zika virus worldwide, most prominently in the Americas during 2015 and 2016, there has been increased recognition of the importance of sexual transmission. We review human reports and animal model studies of Zika sexual transmission and summarize potential therapeutic candidates. RECENT FINDINGS: Male-to-female, male-to-male, and female-to-male transmission has been reported, among unprotected sexual contacts of returning travelers. Human studies have shown the potential importance of long-term persistence of Zika virus in semen while animal models have begun to yield important insights into pathogenesis of Zika infection of the genital tract. Adherence to federal and global guidelines for prevention of sexual transmission of Zika virus from travelers to their sexual partners represents the best strategy for reducing the risk of transmission outside of endemic areas. Active research on potential treatments may soon yield candidates for clinical trials.

RESUMEN

Pregnancies are frequently unplanned, and higher rates of unplanned pregnancies occur among HIV-infected women. Reviewers examined reproductive decision making, conception practices, and patient-provider communication among women living with HIV. Qualitative interviews were conducted with 19 HIV-infected sexually active women aged 18-45 in southern Florida, USA. Using thematic analysis, we found decisions to conceive were influenced by women and partners; knowledge and use of safer conception practices were low. Discussion and support from partners, family, and providers was limited and diminished by stigma and nondisclosure. Preconception counseling discussions in HIV care should be comprehensive and initiated frequently by all health care providers.

RESUMEN

The development of methods to achieve efficient reprogramming of human cells while avoiding the permanent presence of reprogramming transgenes represents a critical step toward the use of induced pluripotent stem cells (iPSC) for clinical purposes, such as disease modeling or reconstituting therapies. Although several methods exist for generating iPSC free of reprogramming transgenes from mouse cells or neonatal normal human tissues, a sufficiently efficient reprogramming system is still needed to achieve the widespread derivation of disease-specific iPSC from humans with inherited or degenerative diseases. Here, we report the use of a humanized version of a single lentiviral "stem cell cassette" vector to accomplish efficient reprogramming of normal or diseased skin fibroblasts obtained from humans of virtually any age. Simultaneous transfer of either three or four reprogramming factors into human target cells using this single vector allows derivation of human iPSC containing a single excisable viral integration that on removal generates human iPSC free of integrated transgenes. As a proof of principle, here we apply this strategy to generate >100 lung disease-specific iPSC lines from individuals with a variety of diseases affecting the epithelial, endothelial, or interstitial compartments of the lung, including cystic fibrosis, α-1 antitrypsin deficiency-related emphysema, scleroderma, and sickle-cell disease. Moreover, we demonstrate that human iPSC generated with this approach have the ability to robustly differentiate into definitive endoderm in vitro, the developmental precursor tissue of lung epithelia.
