Key take-home messages PEP initiated soon after exposure can reduce the risk of HIV seroconversion after occupational and non-occupational exposures, provided adherence to medications is sufficient (1–4). Evidence suggests that individuals prescribed tenofovir-based two- or three-drug regimens are more likely to complete a course of PEP and have lower discontinuation rates due to adverse events compared to zidovudine-based

Key take-home messages Economic evaluations of health care interventions can inform resource allocation and policy development. However, interpreting and generalizing results can be challenging (1). PrEP can be cost-effective or cost-saving depending on the local context, adherence rates, and program coverage (1). Interventions that target individuals at high risk of HIV exposure may improve the cost-effectiveness of PrEP (1–3). Non-occupational PEP may be cost-effective, or even cost-saving

4. HIV in pregnancy: Identification of intrapartum and perinatal HIV exposures

HIV in pregnancy: Identification of intrapartum and perinatal HIV exposures The benefits of human immunodeficiency virus (HIV) testing in pregnancy, when combined with appropriate maternal antiretroviral therapy and intrapartum and postnatal prophylaxis, are well established. The vertical rate of transmission of HIV in North America is now well below 2%. Efforts must continue to ensure that these benefits are sustained. Women who have received little or no prenatal care and those who present (...) for delivery with unknown HIV status need immediate testing. As more infants are exposed to antiretroviral agents, strategies need to be implemented to ensure adequate follow-up of these infants. Issues relating to the identification of HIV-exposed infants are highlighted. Keywords: Human immunodeficiency virus; Infant; Intrapartum transmission; Pregnancy; Screening

9. Effects of adolescent exposure to behaviour change interventions on their HIV risk reduction in Northern Malawi: a situation analysis (PubMed)

Effects of adolescent exposure to behaviour change interventions on their HIV risk reduction in Northern Malawi: a situation analysis Understanding adolescents' translation of HIV and AIDS-related behaviour change interventions (BCI) knowledge and skills into expected behavioural outcomes helps us appreciate behaviour change dynamics among young people and informs evidence-based programming. We explored the effects of adolescents' exposure to BCI on their HIV risk reduction in selected schools (...) model isolated sexual experience ([Beta = .727, p = .0001, p < .05]) as having the strongest correlation with the dependent variable - risk reduction. BCI exposure was stepwise excluded ([Beta = -.082, p = .053, p > .05]). There was therefore no evidence against the null hypothesis of no relationship between adolescent exposure to BCI and their HIV risk reduction. Overall there was limited BCI knowledge and skills translation to behavioural risk reduction. The study points to the need to evaluate

However, the period during which PEP is most efficacious is often said to be within (...) 72 hours of exposure. Most exposures have only a low risk of HIV transmission even in the absence of PEP. PEP given to HIV-negative people reduces likelihood of HIV seroconversion by approximately 80%. Duration of treatment is 28 days. New antiretroviral treatment regimens for PEP offer low risk of toxicity. There is an absence of randomised controlled studies evaluating PEP. Definition Post-exposure prophylaxis (PEP) is the administration of antiretroviral therapy (ART) to HIV-negative people

15. Recent advances in pre-exposure prophylaxis for HIV. (PubMed)

Recent advances in pre-exposure prophylaxis for HIV. Although pre-exposure prophylaxis (PrEP)-the use of antiretroviral drugs by non-infected people to prevent the acquisition of HIV-is a promising preventive option, important public health questions remain. Daily oral emtricitabine (FTC)-tenofovir disoproxil fumarate (TDF) is highly efficacious in preventing the acquisition of HIV in people at risk as a result of a range of different types of sexual exposure. There is good evidence of efficacy (...) of this treatment on the incidence of sexually transmitted infections (STIs) at a population level. Many challenges remain. Access to pre-exposure prophylaxis is limited and disparities exist, including those governed by race and sex. Different pricing and access models need to be explored to avoid further widening inequalities. The optimal combination prevention program needs to be defined, and this will depend on local epidemiology, service provision, and cost effectiveness. This review updates the evidence

Pre-exposure prophylaxis is the use of certain antiretroviral medications by HIV-uninfected per- sons who are at high, ongoing risk of HIV acquisition, beginning before and continuing after potential HIV exposures. Postexposure prophy- laxis (PEP) involves 28 days of antiretroviral medications immediately after a specific HIV exposure, and is “nonoccupational” (nPEP) when used after sexual and injection drug use exposures, rather than acci- dental

Occupational exposure, attitude to HIV-positive patients and uptake of HIV counselling and testing among health care workers in a tertiary hospital in Nigeria Health care workers (HCWs) are at risk of occupational exposure to HIV. Their attitude to HIV-positive patients influences patients' willingness and ability to access quality care. HIV counselling and testing (HCT) services are available to inform HCWs and patients about their status. There is little information about HCT uptake (...) and attitude to HIV-positive patients among HCWs in tertiary health facilities in Nigeria. The aim of this study was to determine occupational exposure and attitude to HIV-positive patients and level of uptake of HCT services among HCWs in a tertiary hospital in Nigeria. A cross-sectional design was utilized. A total of 977 HCWs were surveyed using semi-structured, self-administered questionnaires. Nurses and doctors comprised 78.2% of the respondents.
