RESUMO
The provision of specialized spine care in Nigeria presents a pressing challenge amid limited resources and geographical disparities. This correspondence offers a comprehensive roadmap for improving spine surgery and care within the country. We examine the current state of spinal health infrastructure, highlighting barriers such as limited access to specialists and facilities, particularly in rural areas, and financial constraints for patients. Innovations in spinal treatment, including the adoption of minimally invasive techniques and advancements in surgical modalities, are discussed alongside persistent challenges such as disparities in access and equipment costs. Training and education of spine surgeons emerge as critical areas requiring attention, with a shortage of qualified professionals exacerbated by inadequate training programs and resource constraints. We advocate for fostering local and international collaborations to address these gaps, emphasizing the role of partnerships in capacity building and knowledge exchange. Additionally, we explore the potential of public-private partnerships and investments to enhance the Nigerian spine healthcare system, calling for strategic initiatives to modernize infrastructure and improve accessibility. Finally, we propose a strategic blueprint encompassing infrastructure enhancement, training programs, research initiatives, policy advocacy, and public awareness campaigns. Through concerted efforts from local stakeholders and international partners, we envision a future where spine care in Nigeria is comprehensive, accessible, and of high quality, leading to improved health outcomes and a higher quality of life for those affected by spinal conditions.

PURPOSE: Prostate cancer disproportionately affects men of African descent, yet their representation in tissue-based studies is limited. This multinational, multicenter pilot study aims to establish the groundwork for collaborative research on prostate cancer in sub-Saharan Africa. METHODS: The Men of African Descent and Carcinoma of the Prostate network formed a pathologist working group representing eight institutions in five African countries. Formalin-fixed paraffin-embedded prostate tissue specimens were collected from Senegal, Nigeria, and Ghana. Histology slides were produced and digitally scanned. A central genitourinary pathologist (P.L.) and eight African general pathologists reviewed anonymized digital whole-slide images for International Society of Urological Pathology grade groups and other pathologic parameters. Discrepancies were re-evaluated, and consensus grading was assigned. A virtual training seminar on prostate cancer grading was followed by a second assessment on a subcohort of the same tissue set. RESULTS: Of 134 tissue blocks, 133 had evaluable tissue; 13 lacked cancer evidence, and four were of insufficient quality. Post-training, interobserver agreement for grade groups improved to 56%, with a median Cohen's quadratic weighted kappa of 0.83 (mean, 0.74), compared with an initial 46% agreement and a quadratic weighted kappa of 0.77. Interobserver agreement between African pathologist groups was 40%, with a quadratic weighted kappa of 0.66 (95% CI, 0.51 to 0.76). African pathologists tended to overgrade (36%) more frequently than undergrade (18%) compared with the reference genitourinary pathologist. Interobserver variability tended to worsen with a decrease in tissue quality. CONCLUSION: Tissue-based studies on prostate cancer in men of African descent are essential for a better understanding of this common disease. Standardized tissue handling protocols are crucial to ensure good tissue quality and data. The use of digital slide imaging can enhance collaboration among pathologists in multinational, multicenter studies.

Background: The 2013-2016 West Africa Ebola outbreak highlighted the importance of laboratory capacity to outbreak response while also revealing its long-standing neglect. The outbreak prompted massive international investment into strengthening laboratory services across multiple healthcare settings. Objective: In this article, we explore hospital-based clinical laboratory workers' experiences and perceptions of their everyday working environment in Sierra Leone, and how recent investments in laboratory strengthening have shaped these. Methods: This qualitative study draws on in-depth interviews with eight laboratory workers and participant observation of laboratory practices at a tertiary referral hospital in Freetown between April 2019 and December 2019. Interview and observational data were coded and analysed using a reflexive thematic approach. Results: The Ebola outbreak prompted international investments in automated devices, biosafety training, and a new dedicated infectious diseases laboratory. However, little investment was made in the infrastructure and supply systems needed to sustain routine laboratory work or keep machines functioning. Laboratory workers perceived their work to be under-recognised and undervalued by the government, hospital managers and clinical staff, a perception compounded by under-use of the hospital's laboratory services by clinicians. Conclusion: Understanding laboratory technicians' views, experiences, and priorities is essential to any sustainable laboratory-strengthening effort. Investments in personnel should match investments in technologies and infrastructure for outbreak response. What this study adds: This study contributes to an understanding of how clinical laboratory personnel in Sierra Leone view and experience their work, and introduces the concept of social invisibility to explain these experiences.

OBJECTIVE: Sub-Saharan Africa is one of the regions with the highest burdens of HIV and hepatitis B virus (HBV), but data on the impact of antiretroviral therapy (ART) on HBV DNA suppression is limited. In this study, we aimed to determine the prevalence and associated factors of a positive hepatitis B surface antigen (HBsAg) among people living with HIV, and assess the suppression of ART on HBV replication in people living with HIV in Sierra Leone. METHODS: A cross-sectional study was designed to recruit people living with HIV aged 18 years or older in ten public hospitals in Sierra Leone between August 2022 and January 2023. Statistical analyses were performed using R software. Logistic regression analysis was used to assess factors independently associated with positive HBsAg and HBV DNA suppression. RESULTS: Of the 3106 people living with HIV recruited in this study, 2311 (74.4%) were women. The median age was 36 years, 166 (5.3%) had serological evidence of HBV vaccination. The overall prevalence of HBsAg positivity was 12.0% (95% CI: 10.9% to 13.2%). Male sex (adjusted OR (aOR) 2.11, 95% CI: 1.67 to 2.68; p<0.001) and being separated (aOR 1.83, 95% CI: 1.06 to 3.16, p=0.031; reference group: being married) were independent predictors of HBsAg seropositivity. Among 331 people living with HIV and HBV receiving ART, 242 (73.1%) achieved HBV DNA suppression (below 20 IU/mL). HBV suppression rate was higher in HIV-virally suppressed patients than those with unsuppressed HIV viral load (p<0.001). In addition, the male sex was more likely to have unsuppressed HBV DNA (aOR 1.17, 95% CI: 1.17 to 3.21; p=0.010). CONCLUSIONS: We reported a high prevalence of HBsAg seropositivity and low HBV immunisation coverage in people living with HIV in Sierra Leone. In addition, we observed that ART can efficiently result in a viral suppression rate of HBV infection. Therefore, achieving the global target of eliminating HBV infection by 2030 requires accelerated access to care for people living with HIV and HBV, including HBV testing, antiviral treatment and hepatitis B vaccination.

BACKGROUND: There is limited evidence on COVID-19 vaccination uptake among people living with HIV (PLHIV) and health care workers (HCWs), with the current evidence concentrated in high-income countries. There is also limited documentation in the published literature regarding the feasibility and lessons from implementing targeted vaccination strategies to reach PLHIV and HCWs in low- and middle-income countries. PROGRAM DEVELOPMENT, PILOTING, AND IMPLEMENTATION: We designed and implemented multifaceted strategies to scale up targeted COVID-19 vaccination among PLHIV and HCWs in 11 administrative regions on the mainland of Tanzania plus Zanzibar. An initial 6-week intensification strategy was implemented using a diverse partnership model comprising key stakeholders at the national- and subnational levels. A layered package of strategies included expanding the number of certified vaccinators, creating vaccination points within HIV clinics, engaging HCWs to address their concerns, and building the capacity of HCWs as "champions" to promote and facilitate vaccination. We then closely monitored COVID-19 vaccination uptake in 562 high-volume HIV clinics. Between September 2021 and September 2022, the proportion of fully vaccinated adult PLHIV increased from <1% to 97% and fully vaccinated HCWs increased from 23% to 80%. LESSONS AND IMPLICATIONS: Our intra-action review highlighted the importance of leveraging a strong foundation of existing partnerships and platforms, integrating COVID-19 vaccination points within HIV clinics, and refining strategies to increase vaccination demand while ensuring continuity of vaccine supply to meet the increased demand. Lessons from Tanzania can inform targeted vaccination of vulnerable groups in future health emergencies.

OBJECTIVE: In Ghana, the shifting demographics of stroke incidence towards young adults have prompted the expansion of stroke care and rehabilitation efforts. Nevertheless, the precise impact of stroke rehabilitation remains unclear. We conducted a systematic review to explore the landscape and effects of stroke rehabilitation in Ghana. METHOD: We identified articles on stroke rehabilitation services in Ghana through searches of PubMed, Scopus, Embase, and Web of Science from inception until February 2024. The Critical Appraisal Skills Programme (CASP) Qualitative Checklist was employed to assess the risk of bias in the included studies, supplemented by qualitative synthesis. RESULTS: Among the 213 articles screened, 8 were deemed suitable for review. These studies primarily focused on two groups: stroke survivors (n = 335) and healthcare professionals (HCPs) (n = 257). Many stroke survivors reported significant benefits from telerehabilitation, with increased participation in rehabilitation activities correlating with improved physical and cognitive outcomes. The findings also underscored a lack of knowledge about stroke rehabilitation among HCPs, alongside variations in the availability of protocols and guidelines for stroke management across different hospital levels. CONCLUSIONS: The review reveals several challenges in stroke rehabilitation in Ghana, including disparities in HCPs' perceptions and utilization of rehabilitation services. The findings emphasize the need for comprehensive, patient-centered approaches, standardized training for HCPs, improved resource allocation, and the integration of telehealth to overcome barriers and enhance stroke rehabilitation in Ghana. These insights hold significance not only for Ghana but also for guiding strategies in similar contexts worldwide, aiming to improve stroke rehabilitation outcomes.

AIM: Heart failure (HF) is a major cause of morbidity and mortality in older adults. Randomized controlled trials (RCTs) inform HF policy and practice, but the accurate interpretation of results is contingent on clear and transparent reporting. The CONsolidated Standards Of Reporting Trials (CONSORT) statement serves as a guide to RCT reporting. We evaluated the quality of reporting in HF RCTs in high-impact journals by assessing their adherence to CONSORT. METHODS AND RESULTS: We searched MEDLINE, EMBASE and CINAHL for HF RCTs published in high-impact journals 2000-2020. We assessed the proportion of CONSORT criteria that individual HF RCTs adhered to, and used the Jonckheere-Terpstra test to examine temporal trends in adherence. Multivariable linear regression explored the association between trial characteristics and adherence to CONSORT. Primary analysis assessed adherence to CONSORT 2010 update. A sensitivity analysis assessed adherence to the original (1996) CONSORT criteria. Among 221 RCTs analysed, the mean (standard deviation [SD]) adherence was suboptimal overall (mean [SD] adherence 69.7 [11.5]%) (5513/7913 criteria), with a temporal increase in adherence over the 20-year period (p < 0.001). Factors associated with adherence included publication after versus during/before 2010 (ß = 10.17, 95% confidence interval [CI] 7.64-12.70; p < 0.001); two-group parallel individual-level randomization versus other (including multi-group or cluster randomization) (ß = 5.81, 95% CI 2.88-8.73; p < 0.001); and multicentre versus single-centre trials (ß = 7.26, 95% CI 3.25-11.27; p < 0.001). There was no difference in trial adherence to the updated CONSORT (2010) versus the original (1996) CONSORT criteria, and temporal trends in adherence to both sets of criteria were similar, likely due to overlap between the two sets of criteria. Trials with greater adherence to CONSORT were published in higher impact factor journals, with a positive correlation (r = 0.312; p < 0.001). CONCLUSION: The quality of reporting in HF RCTs, as measured by CONSORT adherence, has improved over time but remains suboptimal.

As antiretroviral treatment (ART) coverage for people living with HIV (PLHIV) increases, HIV programmes require up-to-date information about evolving HIV risk behaviour and transmission risk, including those with low-level viremia (LLV; >50 to ≤1000 copies/mL), to guide prevention priorities. We aimed to assess differences in sexual risk behaviours, distribution of viral load (VL) and proportion of transmission across PLHIV subgroups. We analysed data from Population-based HIV Impact Assessment surveys in 14 sub-Saharan African countries during 2015-2019. We estimated adjusted prevalence ratios (aPR) of self-reported HIV high-risk behaviour (multiple partners and condomless sex) across cascade stages via generalised estimation equations. We modelled the proportions of transmission from each subgroup using relative self-reported sexual risk, a Hill function for transmission rate by VL, and proportions within cascade stages from surveys and UNAIDS country estimates for 2010-2020. Compared to PLHIV with undetectable VL (≤50 copies/mL), undiagnosed PLHIV (aPR women: 1.28 [95% CI: 1.08-1.52]; men: 1.61 [1.33-1.95]) and men diagnosed but untreated (2.06 [1.52-2.78]) were more likely to self-report high-risk sex. High-risk behaviour was not significantly associated with LLV. Mean VL was similar among undiagnosed, diagnosed but untreated, and on ART but non-suppressed sub-groups. Across surveys, undiagnosed and diagnosed but untreated contributed most to transmission (40-91% and 1-41%, respectively), with less than 1% from those with LLV. Between 2010 and 2020, the proportion of transmission from individuals on ART but non-suppressed increased. In settings with high ART coverage, effective HIV testing, ART linkage, and retention remain priorities to reduce HIV transmission. Persons with LLV are an increasing share of PLHIV but their contribution to HIV transmission was small. Improving suppression among PLHIV on ART with VL ≥1000 copies/mL will become increasingly important.
