Advancing prevention of sexually transmitted infections through point-of-care testing : target product profiles and landscape analysis

Objectives: Advancing the field of point-of-care testing (POCT) for STIs can rapidly and substantially improve STI control and prevention by providing targeted, essential STI services (case detection and screening). POCT enables definitive diagnosis and appropriate treatment in a single visit and home and community-based testing. Methods: Since 2014, the WHO Department of Reproductive Health and Research, in collaboration with technical partners, has completed four landscape analyses of promising diagnostics for use at or near the point of patient care to detect syphilis, Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis and the human papillomavirus. The analyses comprised a literature review and interviews. Two International Technical Consultations on STI POCTs (2014 and 2015) resulted in the development of target product profiles (TPP). Experts in STI microbiology, laboratory diagnostics, clinical management, public health and epidemiology participated in the consultations with representation from all WHO regions. Results: The landscape analysis identified diagnostic tests that are either available on the market, to be released in the near future or in the pipeline. The TPPs specify 28 analytical and operational characteristics of POCTs for use in different populations for surveillance, screening and case management. None of the tests that were identified in the landscape analysis met all of the targets of the TPPs. Conclusion: More efforts of the global health community are needed to accelerate access to affordable quality-assured STI POCTs, particularly in low-and middle-income countries, by supporting the development of new diagnostic platforms as well as strengthening the validation and implementation of existing diagnostics according to internationally endorsed standards and the best available evidence

Accelerating the dual elimination of mother-to-child transmission of syphilis and HIV: Why now?

Even though the elimination of congenital syphilis has been on the maternal and child health (MCH) agenda for over a decade, elimination has not yet been achieved; what, then, are the factors currently facilitating the elimination of mother-to-child transmission (MTCT) of syphilis

Factors Influencing Adoption of Emerging Technology of the Banking Sector of Kenya: A Case Study of Commercial Banks in Meru County

The general objective of this research was to find out the factors influencing adoption of emerging technology in the banking sector among Commercial Banks in Meru town. The objectives were to determine whether banking regulation, Competition, Security concerns, Management and cost   influences adoption of technology in the banking sector. The target population was 22 Branch managers, 22 IT managers and 22 Operational Managers. Research adopted descriptive research design methodology strategy so as to enable researcher to describe the state of affairs as they were. The data was analyzed using both quantitative data and qualitative data whereby, the quantitative data collected was analyzed by the use of descriptive statistics using SPSS version 22. Qualitative data was arranged into topics that were similar and was presented by use of narration and tables. Multiple Linear Regression analysis was used to show the relationship between the independent variables and the dependent variable and to test the hypotheses. Research revealed that there was a significant relationship between banking regulation and adoption of technology but there was no relationship between, security concerns, competitions, cost and management in banking sector. The study recommends banks should regularly respond to issues arising from banking regulations, competitions, security, cost and management on adoption of technology in order for their function to serve its purpose

Scoping review protocol to map evidence on South-South learning exchange in family planning

Introduction: South-South learning exchange (SSLE) is an interactive learning process where stakeholder teams exchange knowledge and experience to help one, or both to work towards change, by identifying, adopting and/or strengthening implementation of a best practice. SSLE has been conducted between countries to share knowledge on best practices and policies in family planning. To the best of our knowledge, no scoping review has been conducted to synthesise evidence on SSLE in family planning. In this paper, we outline the protocol to conduct scoping review on SSLE in family planning. Methods and analysis: Arksey and O'Malley's scoping review framework with adaptions from Levac et al will be used to guide this scoping review. We will search electronic databases (Medline, Embase, CINAHL, Hinari, ProQuest DB, PUBMED, Web of Science and WorldCat), grey literature sources and reference lists of included studies. We will focus on literature published till August 2022. The abstract and title screening, full-text screening and data charting will be conducted by two independent reviewers. The findings will be summarised into a narrative based on thematic analysis. Stakeholder interviews will be conducted to understand their perception and experiences in applying SSLE in family planning. Ethics and dissemination: The ethics review committee at WHO, Geneva, has exempted this study from ethical approval (ERC.0003752). The findings from the study will provide useful insights into effective approaches, barriers, facilitators to conduct SSLE in family planning. This knowledge will be of significant public health relevance and will help in designing future learning exchanges between countries in the south to accelerate access to quality family planning services. The findings will be disseminated via peer-reviewed journals, conference proceedings, newsletters and workshops

Scoping review on the use of South-South learning exchange to scale up evidence-based practices in family planning

Background: South-South learning exchange (SSLE) is an interactive learning process where teams from low-income and middle-income countries exchange knowledge and experience to support one or both team's work towards a change in policies, programmes or practices. SSLE has been used by countries to improve family planning (FP) outcomes such as increased contraceptive prevalence rate and reduced unmet need for FP, but at present, there are no reviews that summarise its use. We conducted a scoping review with stakeholder consultations to summarise the use of SSLE to change FP outcomes. Objective: To systematically identify and map the purposes, approaches, outputs, outcomes, enablers and barriers to using SSLE in FP. Methods: A search was conducted on electronic databases, grey literature sources, websites and the reference list of included studies. The scoping review is based on an adapted version of Arksey and O'Malley's scoping review framework suggested by Levac et al. Experts were interviewed on their experiences in SSLE. Results: The initial search yielded 1483 articles; however, only 29 were selected in the final analysis. The articles were published between 2008 and 2022. Most of the articles were reports, case studies or press releases, only two were peer-reviewed publications. Capacity building of FP providers, policy-makers and community was the most commonly reported purpose of SSLE, with study tours (57%) being the most common approach. Policy dialogue was the most common (45%) output and improved contraceptive prevalence was the most frequently reported outcome. The experiences of the 16 interviewed experts aligned with the scoping review findings. Conclusion: The evidence on the effectiveness of SSLE for addressing FP outcomes is very limited and of very low quality. We call on stakeholders conducting SSLE to document their experiences in detail, including the outcomes achieved

Advancing point of care diagnostics for the control and prevention of STIs: the way forward.

WHO recognises the global impact of sexually transmitted infections (STIs) on global public health and individual sexual and reproductive health and well-being. As a component of the WHO Global Health Sector Strategy for the control and prevention of STIs, there has been a growing recognition of the importance of integrating point-of-care tests (POCTs) into overall strategic planning. The process of integrating STI POCTs, in addition to providing a definitive diagnosis and appropriate treatment in a single visit, also includes innovative delivery options, such as on-site delivery, community-based testing (including screening), as well as self-testing at home after purchase of a test online or over-the-counter. WHO organised two technical consultations in May 2014 and July 2015. This article summarises the discussions of the meeting participants on advancing the use of POCTs to control and prevent STIs. The following priorities were identified: the need for pathogens' target discovery; encouragement of multiplexing, miniaturisation, simplification and connectivity; promotion of standardisation of evaluation of new diagnostic platforms across all stages of the evaluation pipeline; the need for an investment case, modelling and scenarios to ensure buy-in among key stakeholders, including developers and the private sector; the need for norms and standards, including guidelines, to support introduction of STI POCTs in programmes; anticipating potential tensions between different parties at the implementation level; and leveraging on the global initiative, Sustainable Development Goals (SDGs)/global health sector STI strategy, to sustain investment in STI POCT programmes. There is a rich pipeline of diagnostic products, but some have stalled in development. An approach to accelerate the evaluation of new diagnostics is to set up a competent network of evaluation sites ahead of time, harmonise regulatory approval processes with development of models to estimate cost-effectiveness, informed by better STI data. This should result in accelerating policy development. Although it may be some time before good POCTs can be widely implemented in low resource settings, it is important to be a catalyst for continued development and use of these essential tools as an integral part of both the WHO Global Health Sector Strategy and the agenda for 2030

Uptake of prevention of mother to child transmission interventions in Kenya: health systems are more influential than stigma

<p>Abstract</p> <p>Background</p> <p>We set out to determine the relative roles of stigma versus health systems in non-uptake of prevention of mother to child transmission (PMTCT) of HIV-1 interventions: we conducted cross-sectional assessment of all consenting mothers accompanying infants for six-week immunizations.</p> <p>Methods</p> <p>Between September 2008 and March 2009, mothers at six maternal and child health clinics in Kenya's Nairobi and Nyanza provinces were interviewed regarding PMTCT intervention uptake during recent pregnancy. Stigma was ascertained using a previously published standardized questionnaire and infant HIV-1 status determined by HIV-1 polymerase chain reaction.</p> <p>Results</p> <p>Among 2663 mothers, 2453 (92.1%) reported antenatal HIV-1 testing. Untested mothers were more likely to have less than secondary education (85.2% vs. 74.9%, p = 0.001), be from Nyanza (47.1% vs. 32.2%, p < 0.001) and have lower socio-economic status. Among 318 HIV-1-infected mothers, 90% reported use of maternal or infant antiretrovirals. Facility delivery was less common among HIV-1-infected mothers (69% vs. 76%, p = 0.009) and was associated with antiretroviral use (p < 0.001). Although internal or external stigma indicators were reported by between 12% and 59% of women, stigma was not associated with lower HIV-1 testing or infant HIV-1 infection rates; internal stigma was associated with modestly decreased antiretroviral uptake. Health system factors contributed to about 60% of non-testing among mothers who attended antenatal clinics and to missed opportunities in offering antiretrovirals and utilization of facility delivery. Eight percent of six-week-old HIV-1-exposed infants were HIV-1 infected.</p> <p>Conclusions</p> <p>Antenatal HIV-1 testing and antiretroviral uptake was high (both more than 90%) and infant HIV-1 infection risk was low, reflecting high PMTCT coverage. Investment in health systems to deliver HIV-1 testing and antiretrovirals can effectively prevent infant HIV-1 infection despite substantial HIV-1 stigma.</p

Field evaluation of two point-of-care tests for syphilis among men who have sex with men, Verona, Italy

Objectives: The incidence of HIV and syphilis among men who have sex with men (MSM) in Europe has recently increased. Rapid point-of-care tests (POCTs) for syphilis can improve access to screening. The purpose of this study was to evaluate the performance of two syphilis POCTs compared with laboratory tests among MSM. Methods: The study was undertaken in Verona, Italy. Asymptomatic MSM, potentially exposed to syphilis, were enrolled prospectively. The POCTs evaluated were SD Bioline Syphilis 3.0 and Chembio DPP Syphilis Screen & Confirm Assay on both serum and fingerprick blood. The results of the POCTs were read by the naked eye by two independent readers and their concordance assessed. Results: A total of 289 MSM were enrolled in the study. Based on laboratory tests, 35 MSM (12.1%) were TPPA-positive alone and 16 (5.5%) were both Treponema pallidum particle agglutination test (TPPA) and rapid plasma reagin (RPR)-positive. The specificities of both POCTs were above 99% on both serum and fingerstick blood specimens, while sensitivities varied considerably. The sensitivity of the SD Bioline test was lower on fingerprick blood (51.4% and 54.3%, readers 1 and 2, respectively) compared with that on serum (80.0% and 82.9%). In contrast, the Chembio test exhibited similar sensitivity values for serum and fingerprick samples (57.7% and 64.0% on serum vs 65.4% and 69.2% on fingerprick for the treponemal component; 63.6% on both samples by both readers for the non-treponemal component). The positive predictive value ranged between 100% and 93.9% for the treponemal component of both syphilis POCTs, but was lower (76.3%-100%)%) for the non-treponemal component of the Chembio POCT. The negative predictive value surpassed 90% for both tests on both samples. The agreement between readers was very high (>99%). Conclusion: The diagnostic performance of the syphilis POCTs was lower than expected; however, considering the prevalence of syphilis among MSM, POCTs should be recommended to improve syphilis detection among MSM
