Awareness of, willingness to use, and experiences with Pre-exposure prophylaxis among youth in Nigeria.

BACKGROUND: Youth (ages 14-24) in Nigeria have disproportionately high rates of new HIV infection. Pre-exposure prophylaxis could substantially reduce new infections among youth but has not been scaled up. This cross-sectional study aimed to assess Pre-exposure prophylaxis awareness, willingness to use, and prior use of Pre-exposure prophylaxis among youth in Nigeria. METHODS: This is a secondary analysis of cross-sectional data from a quasi-experimental pilot study (clinical trial NCT04070287). The analysis focused on Pre-exposure prophylaxis awareness, willingness to use, and prior use among 324 youth recruited between September 2019 to March 2020. Descriptive statistics were calculated as frequencies and percentages for categorical variables and means and standard deviations for continuous variables. RESULTS: Of the 324 participants, the mean age and standard deviation were 21.17 (± 2.20) years. The majority were 20-24 years old (75.9%) and male (57.7%). Only 30.7% used condoms consistently over three months. Regarding Pre-exposure prophylaxis awareness and willingness, 62.6% had never heard of Pre-exposure prophylaxis, and 158 (50.1%) reported willingness to use Pre-exposure prophylaxis. Only 10 (3.2%) reported having used Pre-exposure prophylaxis. CONCLUSION: Nigerian youth have low awareness of and prior use of Pre-exposure prophylaxis. Given the gap between prior use and willingness to use Pre-exposure prophylaxis, our findings suggest missed opportunities to prevent new HIV infections among youth in Nigeria. Efforts to increase awareness and uptake of Pre-exposure prophylaxis among this population should consider youth-led Pre-exposure prophylaxis outreach efforts and effectively communicate the benefits of Pre-exposure prophylaxis to this population. TRIAL REGISTRATION: NCT04070287, the Date of registration of the trial is 20-07-2019.

Sustaining HIV Research in Resource-Limited Settings Using PLAN (People, Learning, Adapting, Nurturing): Evidence from the 4 Youth by Youth Project in Nigeria.

PURPOSE OF REVIEW: Sustaining evidence-based interventions in resource-limited settings is a perennial challenge. Despite growing research on the significance of sustainability, few frameworks describe why and how to plan for sustainability in settings limited with resources. Drawing on a synthesis of the literature on sustainability, including the Dynamic Sustainability Framework, we review lessons learned from research to date, to point out a path forward for sustaining evidence-based interventions in resource-limited settings. RECENT FINDINGS: We describe PLAN or why people learning, adapting, and nurturing the core values of an intervention can enhance its sustainability over time. PLAN is a dynamic framework that simplifies the process of planning for sustainability of evidence-based interventions throughout the lifecyle of an intervention, taking into consideration the people that matter as well as the learning, adaptation, and nurturing involved with understanding and studying the interactions between interventions/innovations, practice settings, intervention fit, and the broader ecological contexts in which implementation occurs. We use case-study data from our ongoing pragmatic HIV implementation trial, the 4 Youth by Youth project, to detail the value and implications of why people learning, adapting, and nurturing HIV interventions implemented in resource-limited settings matter. PLAN is designed to further the dialogue on ways research and practice teams can critically work to ensure the sustainability of their evidence-based interventions from the onset, particularly in settings and with populations limited with resources. It also illustrates how attention to sustainability from the beginning may foster actions necessary for sustained program → sustained benefits → sustained capacity → sustained value, but in the absence of early and active planning, none of this will occur. Ultimately, we hope to accelerate the sustainability of evidence-based HIV interventions, and making a PLAN at the bare minimum may ensure that the goals of continuing and maintaining desirable features of any evidence-based interventions can be realized.

Challenges in conducting population-based seroepidemiology survey of COVID-19 in Lagos State, Nigeria.

Population-based study is known to be a very essential type of study during and after a pandemic or epidemic, as it provides crucial information on the incidence, prevalence, and risk factors of the disease in question. There has been limited information about the challenges faced in conducting such surveys in Nigeria. In this paper, we will share our experience, and describe the challenges faced in conducting a population-based seroepidemiological study of COVID-19 in Lagos, Nigeria. Some challenges were peculiar to specific Local Government Areas (LGAs) while others were general. The challenges include general misconceptions of community members about health research, difficulties in mapping houses, planning for data collection, standardizing data collection, working in hard-to-reach communities when resources were limited as well as difficulty in collection of blood and naso-oropharyngeal swabs. Ways of overcoming these problems, lessons learnt, and recommendations are hereby discussed.

Training primary healthcare workers on a task-strengthening strategy for integrating hypertension management into HIV care in Nigeria: implementation strategies, knowledge uptake, and lessons learned.

BACKGROUND: With improved access to anti-retroviral drugs, persons living with HIV/AIDS (PLWHA) are living longer but with attendant increased risks of non-communicable diseases (NCDs). The increasing burden of NCDs, especially hypertension, could reverse gains attributed to HIV care. Nurses and Community Health Officers (CHO) in Nigeria are cardinal in delivering primary health care. A task-strengthening strategy could enable them to manage hypertension in HIV care settings. This study aimed to assess their knowledge and practice of hypertension management among Healthcare workers (HCWs) and to explore the challenges involved in conducting onsite training during pandemics. METHODS: Nurses and CHOs in the employment of the Lagos State Primary Health Care Board (LSPHCB), Lagos State, Nigeria, were recruited. They were trained through hybrid (virtual and onsite) modules before study implementation and a series of refresher trainings. A pre-and post-training test survey was administered, followed by qualitative interviews to assess skills and knowledge uptake, the potential barriers and facilitators of task-sharing in hypertension management in HIV clinics, and the lessons learned. RESULTS: Sixty HCWs participated in the two-day training at baseline. There was a significant improvement in the trainees' knowledge of hypertension management and control. The average score during the pre-test and post-test was 59% and 67.6%, respectively. While about 75% of the participants had a good knowledge of hypertension, its cause, symptoms, and management, 20% had moderate knowledge, and 5% had poor knowledge at baseline. There was also an increase in the mean score between the pre-test and post-test of the refresher training using paired t-tests (P < 0.05). Role-playing and multimedia video use improved the participants' uptake of the training. The primary barrier and facilitator of task sharing strategy in hypertension management reported were poor delineation of duties among HCWs and the existing task shifting at the Primary Healthcare Centres (PHC) level, respectively. CONCLUSIONS: The task strengthening strategy is relevant in managing hypertension in HIV clinics in Nigeria. The capacity development training for the nurses and CHOs involved in the Integration of Hypertension Management into HIV Care in Nigeria: A Task Strengthening Strategy (TASSH-Nigeria) study yielded the requisite improvement in knowledge uptake, which is a reassurance of the delivery of the project outcomes at the PHCs.

Digital sexually transmitted infection and HIV services across prevention and care continuums: evidence and practical resources.

Increased demand for sexual health services (including prevention and treatment) have spurred the development of digital STI/HIV services. Earlier advances in testing technologies opened the door for self-testing and self-sampling approaches, in line with broader self-care strategies. Advances in HIV management mean that many people are living well with HIV and no longer need intensive in-person monitoring, whereas those at-risk of HIV are recommended to have regular asymptomatic STI screening and pre-exposure prophylaxis. This narrative review examines the evidence and implications of digital STI/HIV services, focused on promoting testing, facilitating testing, clinical management and referrals, partner services, and prevention. We have used a prevention and care continuum to structure the review to increase utility to policy as well as practice. Digital STI/HIV services can be interwoven into existing clinical pathways to enhance face-to-face services or standalone digital STI/HIV services. A growing evidence base, including randomised controlled trials and observational studies, should help inform strategies for designing effective digital STI/HIV services. However, most studies to date have focused on high-income countries and people with smartphones, despite a substantial burden of STI/HIV in low- and middle-income countries. There are also important differences between digital STI and HIV services that require careful consideration. We discuss digital STI/HIV service evidence and implications to inform research and programs in this exciting field.

Antimicrobial resistance awareness and antibiotic prescribing behavior among healthcare workers in Nigeria: a national survey.

BACKGROUND: Antimicrobial resistance (AMR) is a global problem compromising the effective treatment of infectious diseases. The World Health Organization (WHO) is encouraging and promoting awareness creation among health workers as one of its strategies to reduce the rate of emergence and transmission of AMR. Available data on the prescribing behavior of healthcare workers (HCWs) in Nigeria remains incomplete. This study was designed to provide an up-to-date estimate of the knowledge, attitude and antibiotic prescribing behavior of HCWs in Nigeria. METHODS: This is a cross-sectional study. Self-administered questionnaires were distributed to healthcare workers selected from six states, one each from the 6 geopolitical zones in Nigeria. A multi-stage sampling technique was used to reflect the three tiers of healthcare: primary, secondary and tertiary levels. Quantitative data was summarized using descriptive statistics. All data analysis was done using the Statistical package for social sciences version 26.0. RESULTS: Of the 420 questionnaires distributed, 358 (85.2%) responded. The mean year of practice of the respondents was 9.32 ± 7.8 years. About a half (50.3%) agreed that their prescribing behavior could promote antimicrobial resistance. 49.2% had a good knowledge of AMR and physicians had significantly better knowledge than other HCWs (X2 = 69.59, P < 0.001). Several participants prescribed antibiotics for common viral infections such as sore throats (75.7%), measles (37.7%), common cold and flu (21.2%). Over 60.3% admitted prescribing antibiotics just to be on the safe side. In general, 70.9% of the respondents frequently or moderately use practice guidelines while 25.7% often apply the delayed antibiotic prescription (DAP) strategy to reduce antimicrobial prescription. CONCLUSION: This study reveals an overall moderate level of knowledge of AMR and attitude towards minimizing the emergence of antimicrobial resistance though this did not translate significantly to practice. Further efforts must be made in order to improve rational prescription of antimicrobials among HCWs in Nigeria.

A designathon to co-create community-driven HIV self-testing services for Nigerian youth: findings from a participatory event.

BACKGROUND: Youth are at high risk for HIV, but are often left out of designing interventions, including those focused on adolescents. We organized a designathon for Nigerian youth to develop HIV self-testing (HIVST) strategies for potential implementation in their local communities. A designathon is a problem-focused event where participants work together over a short period to create and present solutions to a judging panel. METHODS: We organized a 72-h designathon for youth (14-24 years old) in Nigeria to design strategies to increase youth HIVST uptake. Proposals included details about HIVST kit service delivery, method of distribution, promotional strategy, and youth audience. Teams pitched their proposals to a diverse seven-member judging panel who scored proposals based on desirability, feasibility, potential impact and teamwork. We examined participants' socio-demographic characteristics and summarized themes from their HIVST proposals. RESULTS: Forty-two youth on 13 teams participated in the designathon. The median team size was 3 participants (IQR: 2-4). The median age was 22.5 years (IQR: 21-24), 66.7% were male, 47.4% completed tertiary education, and 50% lived in Lagos State. Themes from proposals included HIVST integration with other health services, digital marketing and distribution approaches, and engaging students. Judges identified seven teams with exceptional HIVST proposals and five teams were supported for further training. CONCLUSIONS: The designathon provided a structured method for incorporating youth ideas into HIV service delivery. This approach could differentiate HIV services to be more youth-friendly in Nigeria and other settings.

Young people's preferences for HIV self-testing services in Nigeria: a qualitative analysis.

BACKGROUND: HIV self-testing (HIVST) provides young people with a convenient, discreet, and empowering way to know their HIV status. However, there is limited knowledge of young people's preferences for HIVST services and potential factors that may influence the uptake of HIVST among this population. The purpose of this research was to use qualitative methods to examine HIVST preferences among Nigerian youth. METHODS: Semi-structured in-depth interviews with a purposive sample of young people 14-24 years old were conducted in Lagos, Nigeria. Data were analyzed thematically to identify themes and domains related to preferences and factors influencing the use of HIV self-testing. RESULTS: A total of 65 youth with mean age of 21 years, were interviewed, and the majority were females (56%). Four themes emerged as the most important characteristics that may influence young people's preferences for HIV self-testing: 1) Cost (i.e. majority of participants noted that they would pay between NGN500 to NGN1,500 naira (USD1.38-USD4.16) for oral HIV self-testing kits); 2) Testing method (i.e. although blood-based sample kits were more popular than oral-based self-testing kits, most preferred the oral-based option due to its perceived benefits and for some, phobia of needles); 3) Access location (i.e. participants suggested they preferred to obtain the HIVST kits from youth-friendly centers, pharmacies, private health facilities, and online stores); and 4) Continuing care and support (i.e. participants highlighted the importance of linkage to care with trained youth health workers for positive or negative test results or toll-free helpline). CONCLUSION: HIV self-testing preferences among Nigerian youth appear to be influenced by several factors including lower cost, less invasive testing method, location of testing, and linkage to care and support post testing. Findings underscore the need to address young people's HIV self-testing preferences as a foundation for implementing programs and research to increase the uptake of HIVST.

Addressing Stroke Literacy in Nigeria Through Music: A Qualitative Study of Community Perspectives.

BACKGROUND: The incidence of stroke in Nigeria is unknown, but stroke literacy, defined here as awareness of stroke warning symptoms and risk factors may be poor in high-risk communities. Although there is growing recognition of the use of music as a conduit to promote health literacy, African music is often overlooked as a source of health information. We sought to understand community-level perspectives on using African music to promote acute stroke literacy. METHODS: A purposive sample of education, health and music professionals, high school and university students were recruited to participate in the qualitative study. Study participants completed a brainstorming exercise that elicited their perceptions of potential barriers and facilitators to the use of music to promote acute stroke literacy in Nigeria. Content analysis was used to identify key themes emerging from the brainstorming exercise. RESULTS: A total of 44 individuals, comprising of 25 students with a mean age of 15.9 ± 1.6 years (52% females) and 19 professionals with a mean age of 39 ± 7.7 years (57.9% males) participated in the brainstorming exercise. Facilitators to the use of music to promote acute stroke literacy in Nigeria include the cultural relevance of music, the ubiquity of music, and government involvement. Key barriers include religious beliefs that discourage the use of "secular" music, cost-related barriers, and limited government support. CONCLUSIONS: Findings from this study provide guidance aimed at improving acute stroke literacy in Nigeria, particularly the importance of government involvement in the development and implementation of stroke literacy interventions guided by African music. Future work should consider implementing interventions that leverage the cultural elements of African music and further assess the extent to which these identified facilitators and/or barriers may influence stroke literacy.

Musculoskeletal symptoms and non-prescribed treatments are common in an urban African population of people living with HIV.

There are no data from West Africa reporting musculoskeletal (MSK) disease in people living with HIV (PLWH). Our primary outcome was to measure the prevalence of MSK symptoms in PLWH in urban West Africa. Our secondary outcomes were to describe the disability, impact on work and treatment use associated with the presence of MSK pain. We conducted an e-questionnaire-based point prevalence study of musculoskeletal symptoms, associated disability and treatment in 292 PLWH attending routine follow-up in Lagos, Nigeria. Seventy-three (25%) patients reported MSK pain; 28 (38%) reported chronic symptoms (> 3 months). HIV suppression rates were high in this population (n = 240, 82%) and comparable between individuals with and without chronic pain. MSK pain was associated with female gender and higher body mass index (BMI). Mechanical pain was the most common pain syndrome identified (n = 34, 47%). Lumbar spine and knee were the most common sites. Chronic pain was associated with increased disability compared with the presence of any MSK pain. High rates of treatment-seeking behaviour were seen in those individuals reporting MSK pain (n = 62, 85%). The majority of these individuals sought traditional treatments (n = 48, 66%). Chronic MSK pain and non-prescribed treatments are common in PLWH established on ART in urban West Africa. Studies are required to measure the long-term impact of these symptoms and medicines on retention in HIV care and ART adherence, besides other long-term health outcomes.

Interventions connecting young people living in Africa to healthcare; a systematic review using the RE-AIM framework.

Introduction: Africa's young people are among the least focused groups in healthcare linkage. The disproportionally high burden of youth-related health problems is a burden, especially in developing regions like Africa, which have a high population of young people. More information is needed about factors that impact linkages in healthcare and the sustainability of health interventions among young people in Africa. Methods: A systematic literature search was performed from October 2020 to May 2022 in PubMed, CINAHL, Scopus, Global Health, and the Web of Science. Studies included in the review were conducted among young people aged 10-24 living in Africa, written in English, and published between 2011 and 2021. Results were reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Data was analyzed using narrative synthesis, synthesizing the details of the RE-AIM reporting component. Interventions were systematically compared using the Cochrane Collaboration risk-of-bias tool to evaluate the rigor of each intervention. Results: A total of 2,383 potentially relevant citations were obtained after an initial database search. Retained in the final group were seventeen articles from electronic data searches; among these articles, 16 interventions were identified. Out of the seventeen studies, nine (53%) were randomized controlled trials, three (18%) were quasi-experimental designs, and five (29%) were observational studies. At the same time, the included interventions were reported on 20 (76.92%) of the 26 components of the RE-AIM dimensions. In eastern Africa, twelve (80%) interventions were conducted, and all the interventions addressed linkage to care for young people in preventing and treating HIV. The least reported RE-AIM dimensions were implementing and maintaining interventions connecting young people to care. Discussion: Timely care remains critical to treating and preventing ailments. This review indicates that interventions created to link young people to care, especially HIV care, can help link them to health care and strengthen the programs. It is also clear that further research with more extended follow-up periods is needed to examine connections to care in all other aspects of health and to bridge the gap between research and practice in the care of young people in Africa.

Expanding Youth-Friendly HIV Self-Testing Services During the COVID-19 Pandemic: Qualitative Analysis of a Crowdsourcing Open Call in Nigeria.

BACKGROUND: HIV self-testing (HIVST) among young people is an effective approach to enhance the uptake of HIV testing recommended by the World Health Organization. However, the COVID-19 pandemic disrupted conventional facility-based HIV testing services, necessitating the exploration of innovative strategies for the effective delivery of HIVST. OBJECTIVE: This study analyzed the outcomes of a digital World AIDS Day crowdsourcing open call, designed to elicit youth responses on innovative approaches to promote HIVST among young people (14-24 years) in Nigeria during COVID-19 restrictions. METHODS: From November 2 to 22, 2020, a World AIDS Day 2020 crowdsourcing open call was held digitally due to COVID-19 restrictions. The crowdsourcing open call followed World Health Organization standardized steps, providing a structured framework for participant engagement. Young people in Nigeria, aged 10-24 years, participated by submitting ideas digitally through Google Forms or email in response to this crowdsourcing open call prompt: "How will you promote HIV self-testing among young people during COVID-19 pandemic?" Data and responses from each submission were analyzed, and proposed ideas were closely examined to identify common themes. Four independent reviewers (AE, SM, AZM, and TG) judged each submission based on the desirability, feasibility, and impact on a 9-point scale (3-9, with 3 being the lowest and 9 being the highest). RESULTS: The crowdsourcing open call received 125 eligible entries, 44 from women and 65 from men. The median age of participants was 20 (IQR 24-20) years, with the majority having completed their highest level of education at the senior secondary school level. The majority of participants lived in the South-West region (n=61) and Lagos state (n=36). Of the 125 eligible entries, the top 20 submissions received an average total score of 7.5 (SD 2.73) or above. The panel of judges ultimately selected 3 finalists to receive a monetary award. Three prominent themes were identified from the 125 crowdsourcing open call submissions as specific ways that HIVST can adapt during the COVID-19 pandemic: (1) digital approaches (such as gamification, photoverification system, and digital media) to generate demand for HIVST and avoid risks associated with attending clinics, (2) awareness and sensitization through existing infrastructures (such as churches, schools, and health facilities), and (3) partnerships with influencers, role models, and leaders (such as religious and youth leaders and social influencers in businesses, churches, organizations, and schools) to build trust in HIVST services. CONCLUSIONS: The crowdsourcing open call effectively engaged a diverse number of young people who proposed a variety of ways to improve the uptake of HIVST during the COVID-19 pandemic. Findings contribute to the need for innovative HIVST strategies that close critical knowledge and practice gaps on ways to reach young people with HIVST during and beyond the pandemic.

Molecular characterization of the circulating strains of Vibrio cholerae during 2010 cholera outbreak in Nigeria.

This study aimed at characterizing the phenotypic and toxigenic status of circulating strains of cholera during outbreaks in Nigeria, employing molecular typing techniques. Two hundred and one samples of rectal swabs, stool, vomitus, water (from the well, borehole, sachet, stream, and tap) and disinfectants (sodium hypochlorite) were collected from three states in the country. The samples were inoculated on thiosulphate-citrate bile salt-sucrose (TCBS), Cary-Blair transport medium and smeared on glass slides for direct examination. The Vibrio cholerae isolates were serotyped, biotyped, and characterized using PCR of the cytotoxin gene A (ctxA), wbeO1, and wbfO139 gene primer. Of the 201 samples screened, 96 were positive for V cholerae O1 (48%), with 69 (72%) positive for ctxA gene. The results from this study showed that the circulating strains of cholera in Nigeria were of Ogawa serotype, also observed in other outbreaks in Nigeria (1991, 1992, and 1996). However, the strains were of the Classical biotype and were mainly (72%) ctxA gene-positive. This current investigation has confirmed the production of cholera toxin by the circulating strains, and this could be harnessed for possible cholera vaccine production in Nigeria.

An Unstructured Supplementary Service Data System to Verify HIV Self-Testing Among Nigerian Youths: Mixed Methods Analysis of Usability and Feasibility.

BACKGROUND: Mobile health (mHealth) interventions among adolescents and young adults (AYAs) are increasingly available in African low- and middle-income countries (LMICs). For example, the unstructured supplementary service data (USSD) could be used to verify HIV self-testing (HIVST) among AYAs with poor bandwidth. OBJECTIVE: The aim of this study is to describe the creation of an USSD platform and determine its feasibility and usability to promote the verification of HIVST results among AYAs in Nigeria. METHODS: We developed and evaluated a USSD platform to verify HIVST results using a user-centered approach. The USSD platform guided AYAs in performing HIVST, interpreting the result, and providing linkage to care after the test. Following the usability assessment, the USSD platform was piloted. We used a mixed methods study to assess the platform's usability through a process of quantitative heuristic assessment, a qualitative think-aloud method, and an exit interview. Descriptive statistics of quantitative data and inductive thematic analysis of qualitative variables were organized. RESULTS: A total of 19 AYAs participated in the usability test, with a median age of 19 (IQR 16-23) years. There were 11 females, 8 males, and 0 nonbinary individuals. All individuals were out-of-school AYAs. Seven of the 10 Nielsen usability heuristics assessed yielded positive results. The participants found the USSD platform easy to use, preferred the simplicity of the system, felt no need for a major improvement in the design of the platform, and were happy the system provided linkage to care following the interpretation of the HIVST results. The pilot field test of the platform enrolled 164 out-of-school AYAs, mostly young girls and women (101, 61.6%). The mean age was 17.5 (SD 3.18) years, and 92.1% (151/164) of the participants reported that they were heterosexual, while 7.9% (13/164) reported that they were gay. All the participants in the pilot study were able to conduct HIVST, interpret their results, and use the linkage to care feature of the USSD platform without any challenge. A total of 7.9% (13/164) of the AYAs had positive HIV results (reactive to the OraQuick kit). CONCLUSIONS: This study demonstrated the usability and feasibility of using a USSD system as an alternative to mobile phone apps to verify HIVST results among Nigerian youth without smartphone access. Therefore, the use of a USSD platform has implications for the verification of HIVST in areas with low internet bandwidth. Further pragmatic trials are needed to scale up this approach.

Using a Designathon to Develop an HIV Self-Testing Intervention to Improve Linkage to Care Among Youths in Nigeria: Qualitative Approach Based on a Participatory Research Action Framework.

BACKGROUND: UNAIDS (Joint United Nations Programme on HIV and AIDS) and the Nigeria National HIV/AIDS Strategic Framework recommend HIV self-testing and youth-friendly services to enhance HIV testing, linkage to health services, and prevention. However, the voices of youths are seldom incorporated into interventions. We examined qualitative data generated from a series of participatory events in partnership with Nigerian youths focused on enhancing linkage to care. OBJECTIVE: The aim of this study was to assess youth-initiated interventions developed during a designathon to improve linkage to care and sexually transmitted infection services. METHODS: This study conducted a designathon informed by crowdsourcing principles and the participatory research action framework. A designathon is a multistage process including an open call, a sprint event, and follow-up activities. The open call solicited Nigerian youths (14-24 years old) to develop intervention strategies for linkage to care and youth-friendly health services. A total of 79 entries were received; from this, a subset of 13 teams responded to the open call and was invited to participate in a sprint event over 72 hours. Narratives from the open-call proposals were analyzed using grounded theory to identify emergent themes focused on youth-proposed interventions for linkage to care and youth-friendly services. RESULTS: A total of 79 entries (through the web=26; offline=53) were submitted. Women or girls submitted 40 of the 79 (51%) submissions. The average age of participants was 17 (SD 2.7) years, and 64 of 79 (81%) participants had secondary education or less. Two main themes highlighted strategies for enhancing youths' HIV linkage to care: digital interventions and collaboration with youth influencers. A total of 76 participants suggested digital interventions that would facilitate anonymous web-based counseling, text prompt referrals, and related services. In addition, 16 participants noted that collaboration with youth influencers would be useful. This could involve working in partnership with celebrities, gatekeepers, or others who have a large youth audience to enhance the promotion of messages on HIV self-testing and linkage. The facilitators of youths' linkage included health facility restructuring, dedicated space for youths, youth-trained staff, youth-friendly amenities, and subsidized fees. Barriers to HIV linkage to care among youths included a lack of privacy at clinics and concerns about the potential for breaching confidentiality. CONCLUSIONS: Our data suggest specific strategies that may be useful for enhancing HIV linkage to care for Nigerian youths, but further research is needed to assess the feasibility and implementation of these strategies. Designathons are an effective way to generate ideas from youths.

Crowdsourcing to support training for public health: A scoping review.

Crowdsourcing is an interactive process that has a group of individuals attempt to solve all or part of a problem and then share solutions with the public. Crowdsourcing is increasingly used to enhance training through developing learning materials and promoting mentorship. This scoping review aims to assess the literature on crowdsourcing for training in public health. We searched five medical and public health research databases using terms related to crowdsourcing and training. For this review, the concept of crowdsourcing included open calls, designathons, and other activities. We used a PRISMA checklist for scoping reviews. Each full-text was assessed by two independent reviewers. We identified 4,071 citations, and 74 studies were included in the scoping review. This included one study in a low-income country, 15 studies in middle-income countries, 35 studies in high-income countries, and 11 studies conducted in multiple countries of varying income levels (the country income level for 12 studies could not be ascertained). Nine studies used open calls, 35 used a hackathon, designathon or other "a-thon" event, and 30 used other crowdsourcing methods, such as citizen science programs and online creation platforms. In terms of crowdsourcing purpose, studies used crowdsourcing to educate participants (20 studies), develop learning materials (17 studies), enhance mentorship (13 studies) and identify trainees (9 studies). Fifteen studies used crowdsourcing for more than one training purpose. Thirty-four studies were done in-person, 31 were conducted virtually and nine used both meeting options for their crowdsourcing events. Seventeen studies generated open access materials. Our review found that crowdsourcing has been increasingly used to support public health training. This participatory approach can be a useful tool for training in a variety of settings and populations. Future research should investigate the impact of crowdsourcing on training outcomes.

Tracking adaptation strategies of an HIV prevention intervention among youth in Nigeria: a theoretically informed case study analysis of the 4 Youth by Youth Project.

BACKGROUND: Although many behavioral interventions are adapted, little is known about the reasons for adaptations and the process and outcomes influencing adaptations. To address this gap, we explored the adaptations made to promote HIV prevention services, including HIV self-testing (HIVST), among Nigerian youth. METHODS: The main objective of this qualitative case study design was to document the adaptations made over time using the Framework for Reporting Adaptations and Modifications - Expanded (FRAME). Between 2018 and 2020, we organized four participatory activities as part of the 4 Youth by Youth project to increase the uptake of HIVST services in Nigeria-an open call, a designathon, a capacity-building bootcamp and a pilot feasibility trial. We also began the process of implementing a final intervention using a pragmatic randomized control trial (RCT). The open call solicited creative strategies to promote HIVST among Nigerian youth and then had experts evaluate them. The designathon brought together youth teams to further develop their HIVST service strategies into implementation protocols. Teams determined to be exceptional were invited to a four-week capacity-building bootcamp. The five teams that emerged from the bootcamp were supported to pilot their HIVST service strategies over a 6-month period. The adapted intervention is currently being evaluated in a pragmatic RCT. We transcribed meeting reports and conducted document reviews of study protocols and training manuals. RESULTS: Sixteen adaptations were identified and categorized into three domains: (1) modifications to the content of the intervention (i.e. photo verification system and/or Unstructured Supplementary Service Data (USSD) system to verify HIVST); (2) modifications to the delivery the intervention (i.e. implement participatory learning community sessions to provide supportive supervision and technical support); (3) modifications to the evaluation processes (i.e. economic evaluation to estimate the cost of implementing intervention on a larger scale). Frequent reasons for adaptation included increasing intervention reach, modifying interventions to enhance their appropriateness and fit with the recipient, and increasing the intervention's feasibility and acceptability. Most adaptations were planned and reactive, and the need for modifications was determined by the youths, 4YBY program staff, and advisory group. CONCLUSIONS: Findings suggest that the nature of adaptations made throughout the implementation process reflects the necessity of evaluating services in context while adjusting to specific challenges as they are identified. Further research is needed to understand the effect of these adaptations on the overall intervention effect as well as the quality of youth engagement.

Incidence of and socio-biologic risk factors for spontaneous preterm birth in HIV positive Nigerian women.

BACKGROUND: Recent studies have identified HIV as a leading contributor to preterm delivery and its associated morbidity and mortality. However little or no information exists in our sub-region on this subject. Identifying the factors associated with preterm delivery in HIV positive women in our country and sub-region will not only prevent mother to child transmission of HIV virus but will also reduce the morbidity and mortality associated with prematurity and low birth weight. This study was designed to determine the incidence and risk factors for preterm delivery in HIV positive Nigerians. METHOD: The required data for this retrospective study was extracted from the data base of a cohort study of the outcome of prevention of mother to child transmission at the Nigerian Institute of Medical Research, Lagos. Only data of women that met the eligibility of spontaneous delivery after 20 weeks of gestation were included. Ethical approval was obtained from the Institution's Ethical Review Board. RESULTS: 181 women out of the 1626 eligible for inclusion into the study had spontaneous preterm delivery (11.1%). The mean birth weight was 3.1 ± 0.4 kg, with 10.3% having LBW. Spontaneous preterm delivery was found to be significantly associated with unmarried status (cOR: 1.7;1.52-2.57), baseline CD4 count <200 cells/mm(3) (cOR: 1.8; 1.16-2.99), presence of opportunistic infection at delivery (cOR: 2.2;1.23-3.57), multiple pregnancy (cOR 10.4; 4.24 - 26.17), use of PI based triple ARV therapy (eOR 10.2; 5.52 - 18.8) in the first trimester (cOR 2.5; 1.77 - 3.52) on univariate analysis. However after multivariate analysis controlling for potential confounding variables including low birth weight, only multiple pregnancy (aOR: 8.6; CI: 6.73 - 12.9), presence of opportunistic infection at delivery (aOR: 1.9; CI: 1.1 - 5.7), and 1st trimester exposure to PI based triple therapy (aOR: 5.4; CI: 3.4 - 7.8) retained their significant association with preterm delivery. CONCLUSION: The spontaneous preterm delivery rate among our cohort was 11.1%. HIV positive women with multiple pregnancies, symptomatic HIV infection at delivery and first trimester fetal exposure to PI based triple therapy were found to be at risk of spontaneous preterm delivery. Early booking and non-use of PI based triple therapy in the first trimester will significantly reduce the risk of preterm delivery.

Sustainability of breastfeeding interventions to reduce child mortality rates in low, middle-income countries: A systematic review of randomized controlled trials.

Child mortality is the lowest it has ever been, but the burden of death in low- and middle-income countries (LMICs) is still prevalent, and the numbers average above the global mean. Breastfeeding contributes to the reduction of child mortality by improving chance of survival beyond childhood. Therefore, it is essential to examine how evidence-based breastfeeding interventions are being maintained in resource-constrained settings. Guided by Scheirer and Dearing's sustainability framework, the aim of this systematic review was to explore how evidence-based breastfeeding interventions implemented to address child mortality in LMICs are sustained. The literature search included randomized controlled trials (RCTs) of breastfeeding interventions from the following electronic databases: Cochrane Library, Global Health, PubMed, Scopus, and Web of Science. Literature selection and data extraction were completed according to the PRISMA guidelines. A narrative synthesis was used to investigate factors that contributed to sustainability failure or success. A total of 497 articles were identified through the database search. Only three papers were included in the review after the removal of duplicates and assessment for eligibility. The three RCTs included breastfeeding interventions predominately focusing on breastfeeding initiation and exclusivity in rural, semi-rural, and peri-urban areas in South Africa, Kenya, and India. The number of women included in the studies ranged from 901 to 3,890, and the duration of studies stretched from 6 weeks to 2.5 years. In two studies, sustainability was reported as the continuation of the intervention, and the other study outlined program dissemination and scale-up. Facilitators and barriers that influenced the sustainability of breastfeeding interventions were largely related to specific characteristics of the interventions (i.e., strong intervention implementers-facilitator; small number of CHWs involved-barrier). Optimizing the sustainability of breastfeeding interventions in LMICs is imperative to reduce child mortality. The focal point of implementation must be planning for sustainability to lead to continued benefits and changes in population outcomes. A defined action plan for sustainability needs to be included in both funding and research.

Understanding factors that promote uptake of HIV self-testing among young people in Nigeria: Framing youth narratives using the PEN-3 cultural model.

It is important to understand how to frame the formats for promoting HIV self-testing to increase uptake among young people. In this study, we used a culture-centered model to understand the narratives of HIV self-testing preferences among young people in Nigeria. We conducted a crowdsourcing contest to solicit ideas surrounding HIV self-testing promotion among young people (10-24 years) in Nigeria from October to November 2018 as part of the 2018 World AIDS Day event. We received 903 submissions and employed thematic content analysis to evaluate 769 eligible youth narratives. Thematic content analysis of the statements from the youth narratives was guided by the PEN-3 cultural model to examine the positive, existential, and negative perceptions (beliefs and values), enablers (resources), and nurturers (roles of friends and family) of HIV self-testing promotion among young people in Nigeria. Several themes emerged as factors that influence the uptake of HIV self-testing among young people in Nigeria. Specifically, seven themes emerged as perceptions: HIV testing accessibility, stigma reduction, and autonomy (positive); HIV self-testing kit packaging and advertisements (existential); lack of knowledge and increased stigma (negative). Seven themes emerged as enablers: social media, school, and government promotion (positive); gamification and animation (existential); high cost and access to linkage to care services (negative); And seven themes emerged as nurturers: peer, families, and faith-based communities (positive); parents and family-centered approach (existential); and partners and family (negative). Our data suggests that increased awareness around HIV self-testing on current youth-friendly platforms, de-stigmatization of HIV and HIV self-testing, decreased prices for HIV self-testing kits, reliability of testing kits, increased linkage to care services, and promotion of self-testing among family members and the community will be beneficial for HIV self-testing scale-up measures among young people in Nigeria.
