RESUMEN
BACKGROUND: Global Health (GH) in Germany increasingly becomes subject of political priority and scientists and policy makers. The aim of this study was to gain understanding of the current state, potential barriers and enablers of interdisciplinarity in GH in the academic sector in Germany. METHODS: Between October 2019 and February 2020, we conducted thirteen semi-structured interviews with ten academics and three policymakers engaged in GH in Germany. Purposive and maximum contrast sampling based on review of the literature was performed to ensure a heterogenous set of study participants. FINDINGS: We found that interdisciplinary exchange in GH research and education is limited in the German academic setting. Several context-specific barriers of interdisciplinary collaboration in the academic sector in Germany were detected, including terminological ambiguities and more biomedical actors being involved in global health compared to other disciplines. At the same time, enablers such as promotion of young academics and fostering topic-specific collaboration in GH research and education were identified to improve interdisciplinary working. CONCLUSION: The importance of following an interdisciplinary approach is discussed and acknowledged across scientists working on GH in Germany. The current challenge is to identify which GH topics lend themselves to the collaboration of Germany-based scientists from various backgrounds and to establish common goals to advance interdisciplinarity research.

INTRODUCTION: The aim of this review was to map evidence of integrating pre-exposure prophylaxis (PrEP) for HIV prevention into family planning services. A comprehensive package, using a combination of PrEP and contraceptive delivery, could reduce the number of new HIV infections and/or unintended pregnancies for at-risk women and adolescent girls. METHODS: A scoping literature search was conducted between August 2020 and October 2020. After developing the review question, electronic databases (MEDLINE, Embase, Cochrane Library, Global Health, Web of Science) were systematically reviewed. All types of articles published from 2012 to August 2020 in English were included. The intended outcome was to identify barriers and enablers of integrating services at the client-level and provider-level. RESULTS: 38 articles met inclusion criteria, with 16 from low-and middle-income countries and 22 from high-income countries. Barriers at the client-level included a lack of risk perception associated with low uptake and continuation of PrEP and pill burden; and at the provider-level, barriers included a lack of studies on cost-effectiveness of integrating services and provider training and knowledge. Facilitators included the initiation of PrEP and contraception at the same time and by the same provider or HIV self-testing. CONCLUSION: Mapping and synthesising current evidence, this review identified key barriers and facilitators for the integration of PrEP into family planning services for women and adolescent girls. In order to address these factors, more implementation research in a variety of settings is needed to meet women's sexual and reproductive health needs globally.

BACKGROUND: HIV self-testing (HIVST) has the potential to increase coverage of HIV testing, but concerns exist about intended users' ability to correctly perform and interpret tests, especially in poor communities with low literacy rates. We assessed the clinical performance of the 2016 prototype OraQuick® HIV Self-Test in rural and urban communities in Zambia to assess the sensitivity and specificity of the test compared to the national HIV rapid diagnostic test (RDT) algorithm and a laboratory reference standard using 4th generation enzyme immunoassays and HIV RNA detection. METHODS: Participants were recruited from randomly selected rural and urban households and one urban health facility between May 2016 and June 2017. Participants received a brief demonstration of the self-test, and then self-tested without further assistance. The research team re-read the self-test, repeated the self-test, drew blood for the laboratory reference, and conducted RDTs following the national HIV testing algorithm (Determine™ HIV1/2 (Alere) confirmed using Unigold™ HIV1/2 (Trinity Biotech)). Selected participants (N = 85) were videotaped whilst conducting the testing to observe common errors. RESULTS: Initial piloting showed that written instructions alone were inadequate, and a demonstration of self-test use was required. Of 2,566 self-test users, 2,557 (99.6%) were able to interpret their result. Of participants who were videoed 75/84 (89.3%) completed all steps of the procedure correctly. Agreement between the user-read result and the researcher-read result was 99.1%. Compared to the RDT algorithm, user-conducted HIVST was 94.1% sensitive (95%CI: 90.2-96.7) and 99.7% specific (95%CI: 99.3-99.9). Compared to the laboratory reference, both user-conducted HIVST (sensitivity 87.5%, 95%CI: 82.70-91.3; specificity 99.7%, 95%CI: 99.4-99.9) and the national RDT algorithm (sensitivity 93.4%, 95%CI: 89.7-96.1%; specificity 100% (95%CI: 99.8-100%) had considerably lower sensitivity. CONCLUSIONS: Self-testers in Zambia who used OraQuick® HIV Self-Test achieved reasonable clinical performance compared to the national RDT algorithm. However, sensitivity of the self-test was reduced compared to a laboratory reference standard, as was the national RDT algorithm. In-person demonstration, along with the written manufacturer instructions, was needed to obtain accurate results. Programmes introducing self-care diagnostics should pilot and optimise support materials to ensure they are appropriately adapted to context.
