Effectiveness of interventions to prevent mother-to-child transmission of HIV in Southern Ethiopia
Behailu Merdekios1, Adebola A Adedimeji2 1College of Medicine and Health Sciences, Arba Minch University, Ethiopia; 2Albert Einstein College of Medicine, Jack and Pearl Resnick Campus, New York, USA Background: In Ethiopia, Progress in Reducing Mother-to-Child-Transmission (PMTCT) of human immunodeficiency virus (HIV) is being curtailed by behavioral and cultural factors that continue to put unborn children at risk, and mother-to-child transmission is responsible for more than 90% of HIV infection in children. The objective of this study was to assess PMTCT services by examining knowledge about reducing vertical transmission among pregnant women. Methods: A multistaged sampling institution-based survey was conducted in 113 pregnant women in Arba Minch. Qualitative and quantitative data were obtained. Results: Of the 113 respondents, 89.4% were from Arba Minch, 43.4% were at least 25 years of age, 73.4% had formal education at primary level or above, 100% reported acceptance of voluntary counseling and testing, 92.0% were knowledgeable about mother-to-child transmission, and 90.3% were aware of the availability of the PMTCT service in the health facility. Of 74 HIV-positive women in PMTCT, only three (4.1%) had had skilled birth attendants at delivery. There was an unacceptable degree of loss of women from PMTCT. Maternal educational level had a statistical association with income (P < 0.001) and voluntary counseling and testing for pregnant women (P < 0.05). Factors that determined use of PMTCT included culture, socioeconomic status, and fear of stigma and discrimination. Conclusion: In the area studied, intervention to reduce mother-to-child transmission of HIV is failing to reach its goal. This is an alarming discovery requiring quick reconsideration and strengthening of preventive strategies at all levels.

HIV Risk Perception and Constraints to Protective Behaviour among Young Slum Dwellers in Ibadan, Nigeria
This study examined the relationship between HIV/AIDS risk perception and protective behaviour among sexually-active urban young slum dwellers in Ibadan, Nigeria. The multistage sampling techniques were used for selecting 1,600 respondents aged 15-24 years. Of these, 1,042 (65%) respondents who reported unprotected sex in the last three months were selected for analysis. Although the sexually-active respondents demonstrated basic knowledge of HIV/AIDS and high risk perception, risky behaviour was common and protective behaviour was poor. About 48% of 505 males and 12% of 537 females had multiple partners. Similarly, 29% of males and 38% of females were engaged in transactional sex. Only 14% of males and 5% of females used any form of protection, resulting in the high rates of sexually transmitted infections reported by 27% of males and 10% of females. Structural and environmental constraints were identified as barriers to adopting protective behaviour. Therefore, programme and policy interventions should be designed to address the peculiar circumstances of urban young slum dwellers to curtail the HIV epidemic

Traversing the cascade: urgent research priorities for implementing the 'treat all' strategy for children and adolescents living with HIV in sub-Saharan Africa
Children and adolescents living with HIV (CALHIV) in sub-Saharan Africa experience significant morbidity and alarmingly high mortality rates due to critical gaps in the HIV care cascade, including late diagnosis and initiation of treatment, as well as poor retention in care and adherence to treatment. Interventions to strengthen the adult HIV care cascade may not be as effective in improving the cascade for CALHIV, for whom specific strategies are needed. Particular attention needs to be paid to the contexts of sub-Saharan Africa, where more than 85% of the world's CALHIV live. Implementing the 'treat all' strategy in sub-Saharan Africa requires dedicated efforts to address the unique diagnosis and care needs of CALHIV, in order to improve paediatric and adolescent outcomes, prevent viral resistance and reduce the number of new HIV infections. We consider the UNAIDS 90-90-90 targets from the perspective of infants, children and adolescents, and discuss the key challenges, knowledge gaps and urgent research priorities for CALHIV in implementation of the 'treat all' strategy in sub-Saharan Africa
Expanding delivery of and access to evidence-based comprehensive HIV/SRH services among men who have sex with men (MSM) and transgender persons in Nigeria
The goals of this project were to: i) increase comprehensive HIV service delivery among MSM, transgender women, and their sexual partners, ii) build the capacity of a local NGO to function as a one-stop-shop for HIV and STI services, and iii) build evidence around the “hub and spokes” service delivery model, how to best reach transgender populations, and to pilot an intervention intended to promote mental health and reduce intersectional, internalized stigma experienced by sexual and gender minorities (both living with HIV and at risk of HIV acquisition). The project implemented a “hub and spokes” model of service provision of comprehensive HIV, sexual and reproductive health and support services to MSM and transgender women in Lagos. Key opinion leaders were essential in creating demand among their large social networks for services at the hub (a one-stop-shop facility) and public health facilities (spokes) that were trained to be a key-population friendly facility. Public health facilities can be capacitated to provide key population friendly services. The project also piloted a mental health promotion and stigma reduction intervention for MSM and transgender women, that addressed the mutiple stigmas experienced by sexual and gender minorities (i.e. intersectional stigma). The intervention determined that there is great need for and interest in such a stigma reduction intervention. The project also highlighted the need for more transgender-inclusive programming given the multiple levels of stigma that the community experiences. To reach more key populations, the hub and spokes model of service delivery should be expanded to other regions

Impact of the Mobile Game FightHPV on Cervical Cancer Screening Attendance: Retrospective Cohort Study
Background: The wide availability of mobile phones has made it easy to disseminate health-related information and make it accessible. With gamification, mobile apps can nudge people to make informed health choices, including attending cervical cancer screening.
Objective: This matched retrospective cohort study examined the association between exposure to the FightHPV mobile app gamified educational content and having a cervical exam in the following year.
Methods: Women aged 20 to 69 years who signed an electronic consent form after downloading the FightHPV app in 2017 (intervention group) were matched 1:6 with women of the same age and with the same screening history (reference group) in 2015. To estimate the impact of exposure to the FightHPV app, we estimated cumulative incidence and hazard ratios (HRs) with 95% CIs. We used data from the Norwegian Cervical Cancer Screening Program database and Statistics Norway to determine screening participation and outcomes, respectively.
Results: We matched 3860 women in the control group to 658 women in the intervention group; 6 months after enrollment, 29.6% (195/658) of the women in the intervention group and 15.21% (587/3860) of those in the reference group underwent a cervical exam (P<.01). Women exposed to the FightHPV app were 2 times more likely to attend screening (adjusted HR 2.3, 95% CI 2.0-2.7), during which they were 13 times more likely to be diagnosed with high-grade abnormality (adjusted HR 12.7, 95% CI 5.0-32.5) than the women in the reference group.
Conclusions: Exposure to the FightHPV app significantly increased cervical cancer screening attendance across the various analyses and improved detection of women with high risk for cervical cancer. For the first time, we demonstrated the effectiveness of gamification combined with mobile technology in cancer prevention by empowering women to make active health-related decisions. Gamification can significantly improve the understanding of complicated scientific concepts behind interventions and increase the acceptance of proposed cancer control measures.publishedVersio
Determinants of retention in HIV antiretroviral treatment (ART) in the Cameroon International epidemiology Database to Evaluate AIDS (IeDEA) study clinics: the context of the HIV treat all strategy in Cameroon
Introduction: retaining patients in antiretroviral treatment (ART) is essential for successful outcomes. Unfortunately, Cameroon continues to report suboptimal ART retention. This study focused on identifying determinants of ART retention in three HIV clinics in Cameroon within the HIV treat all context.
Methods: a medical chart review of 423 subjects who initiated ART between July and September 2016 in the Limbe, Bamenda and Jamot Hospitals. Patients' sociodemographic and clinical characteristics and ART retention data were abstracted using structured paper forms. Chi square test was used to assess bivariate associations. Logistic regression was used to adjust for confounders. P-value was set at <0.05 at 95% confidence interval.
Results: the mean age was 40±11 years, and 65.1% were females. Antiretroviral treatment retention after 24 months was 309/392(78.83%) and 30/423(7.1%) were transferred-out, 11/423(2.6%) reported dead and 73/423(17.3%) lost to follow-up. HIV status disclosure (AOR 0.16 95% CI: 0.05-0.51, p<0.01) and age group 31-50 years (AOR 3.63, 95% CI:1.04-12.59, P= 0.04) were associated with lower and higher ART retention respectively.
Conclusion: about a quarter of the participants were not retained in ART after 24 months. Patient-level factors determined ART retention. These factors should be considered in designing strategies to improve ART retention. More research is needed to identify other determinants of ART retention under the HIV treat all strategy
Characteristics of HIV-Infected Children at Enrollment into Care and at Antiretroviral Therapy Initiation in Central Africa
Background Despite the World Health Organization (WHO) regularly updating guidelines to recommend earlier initiation of antiretroviral therapy (ART) in children, timely enrollment into care and initiation of ART in sub-Saharan Africa in children lags behind that of adults. The impact of implementing increasingly less restrictive ART guidelines on ART initiation in Central Africa has not been described.
Materials and Methods Data are from the Central Africa International Epidemiologic Databases to Evaluate AIDS (IeDEA) pediatric cohort of 3,426 children (0±15 years) entering HIV care at 15 sites in Burundi, DRC, and Rwanda. Measures include CD4 count, WHO clinical stage, age, and weight-for-age Z score (WAZ), each at enrollment into HIV care and at ART initiation. Changes in the medians or proportions of each measure by year of enrollment and year of ART initiation were assessed to capture potential impacts of changing ART guidelines.
Results Median age at care enrollment decreased from 77.2 months in 2004±05 to 30.3 months in 2012±13. The median age at ART initiation (n = 2058) decreased from 83.0 months in 2004±05 to 66.9 months in 2012±13. The proportion of children 24 months of age at enrollment increased from 12.7% in 2004±05 to 46.7% in 2012±13, and from 9.6% in 2004±05 to 24.2% in 2012±13 for ART initiation. The median CD4 count at enrollment into care increased from 563 (IQR: 275, 901) in 2004±05 to 660 (IQR: 339, 1071) cells/μl in 2012±13, and the median CD4 count at ART initiation increased from 310 (IQR:167, 600) in 2004±05 to 589 (IQR: 315, 1113) cells/μl in 2012±13. From 2004±05 to 2012±13, median WAZ improved from -2 (IQR: -3.4, -1.1) to -1 (IQR: -2.5, -0.2) at enrollment in care and from -2 (IQR: -3.8, -1.6) to -1 (IQR: -2.6, -0.4) at ART initiation.
Discussion and Conclusion Although HIV-infected children 24 months of age accounted for half of all children enrolling in care in our cohort during 2012±13, they represented less than a quarter of all those who were initiated on ART during the same period. Further research is needed to identify barriers to timely diagnosis, linkage to care, and initiation of ART among children with HIV infection
