HIV infection was associated with significant weight loss before the advent of potent antiretroviral therapy (ART). Weight gain while on treatment was seen as a clinical indicator of treatment success. Perceptions of health care providers (HCPs) about obesity among people living with (PLHIV) were examined. We conducted 16 key informant interviews with HCPs in two states in southeastern Nigeria, which were then coded thematically. The respondents included seven physicians, four nurses, three adherence counselors, and two pharmacists. The analysis revealed three key themes: HCPs do not see excess weight gain as a problem; there are several challenges in managing obesity among PLHIV; and comorbidities play a role in the management of obesity among PLHIV. We conclude that obesity among PLHIV is an important clinical issue that HCPs need to address with the commencement of ART.

To assess schoolchildren’s exposure to outdoor/indoor air pollution and identify those at a higher risk, it is desirable to conduct personal-level air quality monitoring. This paper documents a 2-month voluntary monitoring campaign with students attending the environmental club of the Spring Valley High School in urban Las Vegas, Nevada. The students wore low-cost sensors to log their exposure to PM2.5 (particulate matter with aerodynamic diameters

HIV testing among men is critical to ending the HIV epidemic in sub-Saharan Africa. Using the Multiple Indicator Cluster Survey, 2016/2017, we examined the uptake and determinants of HIV testing among sexually active men in Nigeria. A total of 1254 young people (15-24 years) and 7866 adults (25-49 years) were included in the analysis. We conducted binary logistic regression analyses to estimate the odds ratio (OR) and adjusted OR for testing for HIV in the last 12 months preceding the survey. Approximately 18.7% of men had tested for HIV (young people [17%] vs. adult [19%]

Background Lagos state is the industrial nerve centre of Nigeria and was the epicentre of the 2014 Ebola outbreak in Nigeria as it is now for the current Coronavirus Disease (COVID-19) outbreak. This paper describes how the lessons learned from the Ebola outbreak in 2014 informed the emergency preparedness of the State ahead of the COVID-19 outbreak and guided response. Discussion Following the Ebola outbreak in 2014, the Lagos State government provided governance by developing a policy on emergency preparedness and biosecurity and provided oversight and coordination of emergency preparedness strategies. Capacities for emergency response were strengthened by training key staff, developing a robust surveillance system, and setting up a Biosafety Level 3 laboratory and biobank. Resource provision, in terms of finances and trained personnel for emergencies was prioritized by the government. With the onset of COVID-19, Lagos state was able to respond promptly to the outbreak using the centralized Incident Command Structure and the key activities of the Emergency Operations Centre. Contributory to effective response were partnerships with the private sectors, community engagement and political commitment. Conclusion Using the lessons learned from the 2014 Ebola outbreak, Lagos State had gradually prepared its healthcare system for a pandemic such as COVID-19. The State needs to continue to expand its preparedness to be more resilient and future proof to respond to disease outbreaks. Looking beyond intra-state gains, lessons and identified best practices from the past and present should be shared with other states and countries.

There have been recent concerns about the failure of several global health interventions. Interventions are considered to have failed when they are unable to achieve the intended results. Failure may be linked to how the intervention was designed (design failure) or how it was implemented (implementation failure). Recently, substantial efforts have been employed to improve the outcomes of health interventions. These efforts have led to the development of several theories, models, and frameworks in implementation science to improve the quality of implementation, bridging the divide between evidence and practice. But significant gaps still exist. Whereas much work has been done to develop frameworks and approaches to improve implementation fidelity, not as much effort has been done to guide the adherence of interventions to program theory during the design of the programs. Further, there have been concerns about the applicability of these frameworks in the real-world. This article uses examples to illustrate these gaps and further proposes a pragmatic framework to address identified gaps, thus aiding evidence-informed program design and implementation. The proposed Theory-Design-Implementation (TyDI) framework will support policymakers, program planners and implementers to address potential design and implementation failure, thus improving the fidelity of interventions.

BackgroundThe Plan-Do-Study-Act (PDSA) cycle is fundamental to many quality improvement (QI) models. For the approach to be effective in the real-world, variants must align with standard elements of the PDSA at the design stage. The adapted design must also be implemented with fidelity. Gaps at the adaptation or implementation stages result in design and implementation failures respectively. Using Taylor’s framework, this study evaluates the alignment between theory, design and implementation of the DIVA (Diagnose-Intervene-Verify-Adjust) model, a PDSA variant adapted for Nigeria’s health system performance improvement.MethodsAn iterative consensus building approach was used to develop a scorecard evaluating new conceptual indices of design and implementation of QI interventions (design and implementation index, defects and gaps). The scorecard assigned quantitative scores that measured the extent to which the reported or documented design or implementation activity aligned with Taylor’s theoretical framework.ResultsDesign (adaptation) scores were across all standard features indicating that design was well adapted to the typical PDSA. Conversely, implementation fidelity scores were only optimal with two standard features: prediction-based test of change and the use of data over time. The other features, use of multiple iterative cycles and documentation, had implementation gaps of 17% and 50% respectively. This may imply that observed effectiveness deficits of DIVA may be attributable to implementation rather than design gaps.ConclusionsThe effectiveness of QI interventions depend of good contextual adaptation and implementation fidelity such that core features (theory and internal logic) must not be compromised. This study demonstrates how both adaptation and implementation are important for success of QI interventions. It also presents an approach for evaluating other QI models using Taylor’s PDSA assessment framework as a guide, which might serve to strengthen the theory behind future QI models, and provide guidance on their appropriate use.

In the era of highly active antiretroviral therapy (HAART), obesity is increasingly being reported among people living with HIV (PLHIV). In this study, we reviewed published literature on body mass index (BMI) changes among treatment-naïve adult PLHIV who started HAART and remained on treatment for at least six months. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline, four databases were searched, and results of included studies were synthesized to describe the BMI trend among PLHIV on treatment. The search generated 4948 studies, of which 30 were included in the qualitative synthesis and 18 were eligible for the meta-analysis. All the studies showed an increase in group BMI. HAART was associated with increase in BMI (pooled effect size [ES] = 1.58 kg/m

Social marketing campaigns have been increasingly used in HIV prevention efforts to address barriers to HIV testing. The purpose of this review is to evaluate the social marketing campaigns in the past ten years (2008-2017) that have targeted HIV testing or intent to test as an outcome, and synthesize the results to determine which campaigns work or do not work. The search was conducted using PubMed, Scopus, PsycINFO, EMBASE, and ABI/Inform. The quality assessment tool for quantitative studies developed by the Effective Public Health Practice Project was used to assess study quality. The search generated 373 articles, of which 13 articles met the inclusion criteria. These articles were from 13 distinct campaigns carried out in 9 countries, twelve of which were in high income countries. Sixty-nine percent (

Background: The highest-income countries procured 50 times as many COVID-19 vaccines as low-income countries, a global health inequity that resulted in only 4.6% of the poorest 5th of the world receiving a COVID-19 vaccine. High-income countries are considering vaccine mandates and passports to contain the spread of COVID-19. This study is a curated discourse aimed at examining how vaccine mandates and passports may impact global vaccine equity from an ethics perspective. Study Design: Narrative review adapted for a debate. Methods: In November 2021, we conducted a review of studies examining global vaccine mandates for an upper-level global health course at Northeastern University, Boston, United States (U.S.). In total, 19 upper-level students, one research assistant, and one instructor participated in the data collection, analysis, and discussion. Results: The review showed vaccine mandates are ethical and effective if autonomy-centered alternatives like soft mandates are first exhausted. Unwarranted stringent public health measures degrade public trust. In the U.S. alone, COVID-19-related deaths hovered above 300000 before COVID-19 vaccination began in mid-December 2020. Since then, the number of COVID-19 deaths more than doubled, despite the wide availability of the vaccine. For many low- and middle-income countries (LMICs) vaccines are not available or easily accessible. Global collaboration to facilitate vaccine availability in LMICs should be a priority. Conclusions: It is essential to get as many people as possible vaccinated to return to some normality. However, vaccine mandates and passports need to be used only sparingly, especially when other options have been exhausted.

Objectives Among all known risk factors of preterm birth, psychosocial factors form an intricate collection, which includes a multidimensional spectrum of interrelated mediating mechanisms. The understanding of these interconnected mechanisms is vital for designing targeted interventions to reduce preterm births. The objective of this systematic review was to investigate potential psychosocial maternal factors and their interactions to cause preterm birth. Methods PubMed, CINAHL, Scopus, Medline, and Cochrane Database of Systematic Reviews were searched for U.S.-based English language studies published between 1989 and 2019. Titles, abstracts, and full-texts were screened to determine eligibility for inclusion. Data were extracted from eligible studies using a customized data collection form. The National Institutes of Health assessment tool was utilized for quality assessment. Results Among the 76 full texts that were reviewed, 9 records met the eligibility criteria, and were included in the final review. The included publications addressed psychosocial factors including racial disparity, lifetime racism, neighborhood disadvantage, lack of partner support, childhood maltreatment and life-course variations, including homelessness and marital status. Antenatal stress was identified as a common mechanism through which psychosocial mediators may act to cause preterm birth. Conclusions This review highlights the need for controlling potential risk factors of maternal stress by improving prenatal care, providing proper housing, and establishing conducive social environments for pregnant women. The review also suggests the importance of maternal psychological counselling and extensive maternal health monitoring among minority groups during the pregnancy period.

Background Partner HIV testing during pregnancy has remained abysmally low in sub-Saharan Africa, particularly in Nigeria. Males rarely attend antenatal clinics with their female partners, limiting the few opportunities available to offer them HIV testing. In this study, we evaluated the scale-up of the Healthy Beginning Initiative (HBI), a community-driven evidenced-based intervention to increase HIV testing among pregnant women and their male partners. Our objectives were to determine the: (1) male partner participation rate; (2) prevalence of HIV among male partners of pregnant women; (3) factors associated with HIV positivity among male partners of HIV-positive pregnant women. Methods We reviewed program data of expectant parents enrolled in HBI in Benue State, north-central Nigeria. During HBI, trained lay health workers provided educational and counseling sessions, and offered free onsite integrated testing for HIV, hepatitis B virus and sickle cell genotype to pregnant women and their male partners who participated in incentivized, church-organized baby showers. Each participant completed an interviewer-administered questionnaire on demographics, lifestyle habits, and HIV testing history. Chi-square test was used to compare the characteristics of HIV-positive and HIV-negative male partners. Simple and multivariable logistic regression models were used to determine the association between participants' characteristics and HIV positivity among male partners of HIV-positive women. Results Male partner participation rate was 57% (5264/9231). Overall HIV prevalence was 6.1% (891/14495) with significantly higher rates in women (7.4%, 681/9231) compared to men (4.0%, 210/5264). Among the 681 HIV-positive women, 289 male partners received HIV testing; 37.7% (109/289) were found to be HIV-positive. In multivariate analysis, older age (adjusted odds ratio [aOR]: 2.45, 95% confidence interval [CI]: 1.27–4.72 for age 30–39 years vs.

Despite its scaled-up response for prevention of mother-to-child transmission of HIV (PMTCT), Nigeria still contributes the greatest number of infants infected with HIV worldwide. Drawing on our knowledge, and review of policy documents and research papers, we explored the achievements and challenges in the elimination of mother-to-child transmission of HIV in Nigeria using the WHO’s health systems framework. We found that Nigeria has increased the number of PMTCT sites, decentralized and integrated PMTCT care for expanded service delivery, adopted task-shifting to address the shortage of skilled healthcare providers, explored alternative sources of domestic funding to bridge the funding gap and harmonized the health management information system to improve data quality. Some of the challenges we identified included: difficulty in identifying HIV-infected pregnant women because of low uptake of antenatal care; interrupted supplies of medical commodities; knowledge gaps among healthcare workers; and lack of a national unique identifying system to enhance data quality. While there have been some achievements in the PMTCT program, gaps still exist in the different blocks of the health system. Elimination of mother-to-child transmission of HIV in Nigeria will require the implementation of feasible, culturally acceptable and sustainable interventions to address the health system-related challenges.

Objective The overall increase in global domestic HIV expenditure obscures the specific performances of many sub-Saharan Africa (SSA) countries in local resourcing of their HIV programs. In this study, we explored the pattern and correlates of domestic HIV expenditure in SSA. Study design This is a cross-sectional ecological study. Methods Data were obtained from the Joint United Nations Programme on HIV/AIDS, World Bank, and the World Health Organization. We included 30 countries with available country-reported HIV expenditures between 2012 and 2017. From the most recent data, we examined the domestic (public and private) HIV expenditure as percentage of the total HIV expenditure. Using Spearman's rho, we assessed the correlation between domestic expenditure as percentage of the total HIV expenditure and HIV prevalence, antiretroviral coverage, gross national income (GNI) per capita, domestic general government health expenditure (GGHE-D) as percentage of general government expenditure, and GGHE-D per capita. Significant correlates at bivariate level were included in a multivariate median regression model. Results The median domestic HIV expenditure as percentage of the total HIV expenditure was 24.9% (interquartile range [IQR]: 8.5–39.3%). In 15 of 30 (50%) countries, domestic HIV expenditure as percentage of the total HIV expenditure was ≤25%. In 23 of 30 (77%) countries, public source accounted for >75% of the domestic HIV expenditure. There was a significant positive correlation between domestic expenditure as percentage of total HIV expenditure and GNI per capita (r = 0.52, P = 0.003) and GGHE-D per capita (r = 0.494, P = 0.005). In the multivariate median regression model, only GNI per capita remained statistically significant (β = 0.006, P = 0.004). Conclusions Some countries in SSA are still overly dependent on external support for their HIV response. Although increasing domestic HIV expenditure in these countries may require growth in the economy, governments can improve the fiscal space for HIV response by looking inward for innovative and sustainable funding mechanisms.

Exclusive Breastfeeding (EBF) among human immunodeficiency virus (HIV)-infected mothers is known to be associated with a sustained and significant reduction in HIV transmission and has the potential to reduce infant and under-five mortality. Research shows that EBF is not common in many HIV-endemic, resource-limited settings despite recommendations by the World Health Organization. Although evidence abounds that male partner involvement increases HIV testing and uptake and retention of prevention of mother-to-child transmission interventions, few studies have evaluated the impact of male partners' involvement and decision-making on initiation, maintenance, and sustainment of EBF. We propose a comparative effectiveness trial of Men's Club as intervention group compared to the control group on initiation and sustainment of EBF. Men's Club will provide male partners of HIV-infected pregnant women one 5-hr interactive educational intervention to increase knowledge on EBF and explore barriers and facilitators of EBF and support. Additionally, participating male partners in the Men's Club as intervention group will receive weekly text message reminders during the first 6-week post-natal period to improve initiation and sustainment of EBF. Participants in the Men's Club as control group will receive only educational pamphlets. Primary outcomes are the differences in the rates of initiation and sustainment of EBF at 6 months between the two groups. Secondary outcomes are differences in male partner knowledge of infant feeding options and the intent to support EBF in the two groups. Understanding the role and impact of male partners on the EBF decision-making process will inform the development of effective and sustainable evidence-based interventions to support the initiation and sustainment of EBF.

Background: The unprecedented coverage of mobile technology across the globe has led to an increase in the use of mobile health apps and related strategies to make health information available at the point of care. These strategies have the potential to improve birth outcomes, but are limited by the availability of Internet services, especially in resource-limited settings such as Nigeria. Objective: Our primary objective is to determine the feasibility of developing an integrated mobile health platform that is able to collect data from community-based programs, embed collected data into a smart card, and read the smart card using a mobile phone-based app without the need for Internet access. Our secondary objectives are to determine (1) the acceptability of the smart card among pregnant women and (2) the usability of the smart card by pregnant women and health facilities in rural Nigeria. Methods: We will leverage existing technology to develop a platform that integrates a database, smart card technology, and a mobile phone-based app to read the smart cards. We will recruit 300 pregnant women with one of the three conditions—HIV, hepatitis B virus infection, and sickle cell trait or disease—and four health facilities in their community. We will use Glasgow’s Reach, Effectiveness, Adoption, Implementation, and Maintenance framework as a guide to assess the implementation, acceptability, and usability of the mHealth platform. Results: We have recruited four health facilities and 300 pregnant women with at least one of the eligible conditions. Over the course of 3 months, we will complete the development of the mobile health platform and each participant will be offered a smart card; staff in each health facility will receive training on the use of the mobile health platform. Conclusions: Findings from this study could offer a new approach to making health data from pregnant women available at the point of delivery without the need for an Internet connection. This would allow clinicians to implement evidence-based interventions in real time to improve health outcomes.

Public transit buses, which move more than 5 billion passengers annually in the United States (U.S.), can contribute substantially to the environmental health burden through emitted air pollutants. As a leader in transforming to cleaner bus fleets, the Regional Transport Commission of Southern Nevada (RTC) has been transitioning from diesel to compressed natural gas (CNG) transit buses since 1999. By 2017, ~75% of RTC&rsquo, s buses operating in Clark County, Nevada were CNG-powered. This study assesses the health benefits of the venture using the US Environmental Protection Agency&rsquo, s (EPA) Co-Benefits Risk Assessment (COBRA) model, considering the emission and exposure changes from the 2017 baseline for two hypothetical scenarios: (1) no transition (CC_D) and (2) complete transition (CC_N). The CC_D scenario shows realized health benefits, mostly due to avoided mortality, of $0.79&ndash, 8.21 million per year for 2017 alone, while CC_N suggests an additional $0.88&ndash, 2.24 million annually that could be achieved by completing the transition. The wide range of estimates partly reflects uncertainties in determining diesel bus emissions under business-as-usual. These health benefits were not limited locally, with ~70% going to other counties. Two national-scale scenarios, US_D and US_N, were also constructed to explore the health impact of transitioning from diesel to CNG buses across the U.S. As of 2017, with CNG powering only ~20% of transit bus mileages nationwide, there could be massive unrealized health benefits of $0.98&ndash, 2.48 billion per year including 114&ndash, 258 avoided premature deaths and &gt, 5000 avoided respiratory and cardiovascular illnesses. Taking into account the health benefits, economic costs, and the inter-state nature of air pollution, expanding federal assistances to accelerate a nationwide transition to cleaner bus fleets is highly recommended.

Background: Community-based strategies to test for HIV, hepatitis B virus (HBV), and sickle cell disease (SCD) have expanded opportunities to increase the proportion of pregnant women who are aware of their diagnosis. In order to use this information to implement evidence-based interventions, these results have to be available to skilled health providers at the point of delivery. Most electronic health platforms are dependent on the availability of reliable Internet connectivity and, thus, have limited use in many rural and resource-limited settings. Objective: Here we describe our work on the development and deployment of an integrated mHealth platform that is able to capture medical information, including test results, and encrypt it into a patient-held smartcard that can be read at the point of delivery without the need for an Internet connection. Methods: We engaged a team of implementation scientists, public health experts, and information technology specialists in a requirement-gathering process to inform the design of a prototype for a platform that uses smartcard technology, database deployment, and mobile phone app development. Key design decisions focused on usability, scalability, and security. Results: We successfully designed an integrated mHealth platform and deployed it in 4 health facilities across Benue State, Nigeria. We developed the Vitira Health platform to store test results of HIV, HBV, and SCD in a database, and securely encrypt the results on a Quick Response code embedded on a smartcard. We used a mobile app to read the contents on the smartcard without the need for Internet connectivity. Conclusions: Our findings indicate that it is possible to develop a patient-held smartcard and an mHealth platform that contains vital health information that can be read at the point of delivery using a mobile phone-based app without an Internet connection.
