BackgroundIn our quest to improve pediatric neuro-oncological care in government tertiary institutions, growing calls to set up a recurring monthly MDT meeting finally came to fruition in 2024 despite the challenges characteristic of setting up a new program in a developing nation. A team comprising of, neurosurgeons, pediatric oncologists, radio-oncologists, pathologists, radiologists, and international collaborators from Cape Town and St Jude’s all convened for this monthly virtual meeting. Here we enumerate, reflect on, and map a way forward to address these issues.MethodologyAs we celebrate the first anniversary of the program, we are auditing the cases discussed, interventions done, morbidity and mortality, and explore growth potential going forward.ResultsWe have not only surpassed our expectations in terms of numbers but also realized tangible benefits brought by the multi-disciplinary efforts in streamlining neuro-oncological services in Zimbabwe. Challenges were encountered, and ongoing efforts are aimed at addressing these challenges through further engagement with the international community as well as public-private partnerships, notably the Kidzcan charity organization. Timely imaging, pathology, and radiotherapy capacity as well as the availability of much-needed surgical equipment are some of the notable constraints.ConclusionIn a nutshell, a multidisciplinary approach to neuro-oncological patients affords tailor-made individualized care to every patient and helps in formulating local treatment protocols best suited for our unique challenges. There is still room for improvement through further collaboration. This program can serve as a template for similar programs in resource-limited settings.

ObjectiveTo review the literature on caregiver involvement in infection prevention and control in low- and middle-income country (LMIC) neonatal units (NNUs).IntroductionThere is a high burden and mortality of neonatal infections globally, with most of the burden falling on LMIC. Healthcare-associated infections (HCAIs) are a particular challenge, with neonatal sepsis being one of the most common HCAIs. It is urgent to prevent infections, as both identification and treatment of neonatal sepsis are increasingly difficult in these contexts. Parents are consistently present on NNUs but their involvement in infection prevention and control (IPC) has been underexplored.Inclusion criteriaIncluded studies were carried out in LMIC NNUs and reported on caregivers’ involvement in design, implementation or experience of IPC interventions.MethodsFive databases were searched in four languages and were screened by two authors. Reference searching was carried out of included papers. Data were analysed by each sub-question; caregiver involvement in intervention design (descriptive analysis), caregiver involvement in IPC delivery (quantitative analysis) and caregiver experience of hygiene and care (thematic analysis).Results38 studies were included. Caregiver involvement in IPC design was limited, with examples from four papers. 30 papers contained information about caregiver delivery of IPC interventions. Most activities were related to being educated on IPC, carrying out core IPC activities or providing a specific aspect of an intervention (most frequently Kangaroo Mother Care). 10 papers discussed caregiver experience of NNU hygiene including ethnographic accounts from Ghana, Malawi, Mexico, India and Brazil. Across all contexts hierarchical social structures and challenging communication between healthcare professionals and families was a barrier to effective IPC within NNUs. Families showed a good understanding of core IPC practices and an awareness of contextual challenges of IPC.ConclusionCaregiver involvement in IPC is limited to date. However, interventions such as Kangaroo Mother Care indicate the benefits that can be achieved. Hierarchical structures and communication challenges between healthcare professionals and families are a barrier to inclusion at present and must be addressed in any designed intervention.Supplementary InformationThe online version contains supplementary material available at 10.1186/s13756-025-01643-1.

Neonatal sepsis is a major cause of morbidity and mortality in low-resource settings and accurate, context-appropriate diagnostic methods are urgently needed to improve clinical outcomes. We used data collected using Neotree, an open source digital health intervention tool, from neonates admitted to Sally Mugabe Central Hospital in Harare between February 2021 and September 2024 to model a composite outcome variable comprised of senior clinician-assigned diagnosis at discharge or cause of death and blood culture test results. Three statistical and machine learning algorithms were developed, tuned where appropriate using cross-validation and evaluated. In total, 917 cases of early-onset neonatal sepsis were identified among the 18 345 neonates in our study sample, comprising 664 cases of clinician diagnosis and 253 positive blood culture results. With area under the receiver operating characteristic curve as a metric, LightGBM, a machine learning gradient-boosted tree classifier, performed marginally better (0.712; 95% CI 0.673 to 0.75) than logistic regression (0.687; 95% CI 0.646 to 0.728) on a held-out evaluation dataset. A simple and easily interpretable machine learning model, the k-neighbours classifier, offered comparable performance (0.699; 95% CI 0.662 to 0.736). This study explored the potential advantages of using machine learning in the triage of neonates at risk of sepsis in low-resource settings where gold-standard blood culture test results are often unavailable. While the differences in performance metrics were not statistically significant, the machine learning approaches in our study offer other advantages including more intuitive predictions and the ability to handle missing data without imputation.

The Global Initiative on Sharing All Influenza Data, a public-access database for sharing severe acute respiratory syndrome coronavirus 2 genomic sequencing data, has received significantly less data from African countries compared to the global total. Furthermore, the contribution of these data was infrequent and, for some countries, non-existent. The primary aim of this review is to identify the technological barriers to routine genomic surveillance in Africa. PubMed and Google Scholar were searched for the relevant articles, and other eligible articles were identified from the reference list examination according to the PRISMA checklist. Eighty-four full-text articles were analysed for eligibility, and 49 published full-texted articles were included in the final qualitative analysis. The main technological barriers identified were limited genomic surveillance capacity, limited genomic sequencing infrastructure, lack of resources and skilled or trained scientists, and the high cost of importing, establishing, and maintaining a genomic sequencing facility. The Africa Pathogen Genomics Initiative aims to improve genomic surveillance capacity across Africa, through resources, training, education, infrastructure, and regional sequencing centres. Furthermore, collaborations between African governments and international partners or national, private, and academic institutions are imperative to sustain genomic surveillance in Africa, and investment in genomic sequencing and research and development is paramount. Longer turnaround times interfere with global viral evolution monitoring and national implementation of effective policies to reduce the burden and disease. Establishing effective genomic surveillance systems guides public health responses and vaccine development for diseases endemic in Africa.

Rapid diagnostic tests (RDTs) for coronavirus disease (COVID) are used in low- and middle-income countries (LMICs) to inform treatment decisions. However, to date, it is unclear when this use is cost-effective. Existing analyses are limited to a narrow set of countries and uses. The aim of this study is to assess the cost-effectiveness of COVID RDTs to inform the treatment of patients with severe illness in LMICs, considering real world practice. We assessed the cost-effectiveness of COVID testing across LMICs using a decision tree model, differentiating results by country income level, Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) prevalence, and testing scenario (none, RDTs, polymerase chain reaction tests-PCRs and combinations). LMIC experts defined realistic care pathways and treatment options. Using a healthcare provider perspective and net monetary benefit approach, we assessed both intended (COVID symptom alleviation) and unintended (treatment side effects) health and economic impacts for each testing scenario. We included the side effects of corticosteroids, which are often the only available treatment for COVID. Because side effects depend both on the treatment and the patient's underlying illness (COVID or COVID-like illnesses, such as influenza), we considered the prevalence of COVID-like illnesses in our analyses. We found that SARS-CoV-2 testing of patients with severe COVID-like illness can be cost-effective in all LMICs, though only in some circumstances. High influenza prevalence among suspected COVID cases improves cost-effectiveness, since incorrectly provided corticosteroids may worsen influenza outcomes. In low- and some lower-middle-income countries, only patients with a high index of suspicion for COVID should be tested with RDTs, while other patients should be presumed to not have COVID. In some lower-middle-income and upper-middle-income countries, suspected severe COVID cases should almost always be tested. Further, in these settings, negative test results in patients with a high initial index of suspicion should be confirmed through PCR and, during influenza outbreaks, positive results in patients with a low initial index of suspicion should also be confirmed with a PCR. The use of interleukin-6 receptor blockers, when supported by testing, may also be cost-effective in higher-income LMICs. The cost at which they would be cost-effective in low-income countries ($162 to $406 per treatment course) is below current prices. The primary limitation of our analysis is substantial uncertainty around some of the parameters in our model due to limited data, most notably on current COVID mortality with standard of care, and insufficient evidence on the impact of corticosteroids on patients with severe influenza. COVID testing can be cost-effective to inform treatment of LMIC patients with severe COVID-like disease. The optimal algorithm is driven by country income level and health budgets, the level of suspicion that the patient may have COVID, and influenza prevalence. Further research to better characterize the unintended effects of corticosteroids, particularly on influenza cases, could improve decision making around the treatment of those with COVID-like symptoms in LMICs.

A comprehensive operative report for cancer surgery is crucial for accurate disease staging, risk stratification, and therapy escalation/de-escalation, which affects the outcome. Narrative operative reports may fail to include some critical findings. Furthermore, standardized operative reports can form the basis of a local registry, which is often lacking in limited-resource settings (LRSs). In adult literature, synoptic operative reports (SOR) contain more key findings than narrative operative reports. In the LRSs, where the capacity of diagnostic pathology services is typically suboptimal, the value of a thorough operative report is even greater. The aim of this study was to develop a SOR template to help standardize childhood cancer surgery reporting in LRSs. Twenty-three experts in pediatric cancer with extensive experience practicing in LRSs were invited to participate in a modified Delphi procedure. SOR domains for pediatric oncology surgery were drafted based on a literature search and then modified based on experts' opinions. The experts anonymously answered multiple rounds of online questionnaires until all domains and subdomains reached a consensus, which was predefined as 70% agreement. Sixteen experts participated in the study, and two rounds of the survey were completed. Twenty-one domains were considered relevant, including demographics, diagnosis, primary site, preoperative disease stage, previous tumor biopsy or surgery, preoperative tumor rupture, neoadjuvant therapy, surgical access, type of resection, completeness of resection, tumor margin assessment, locoregional tumor extension, organ resection, intraoperative tumor spillage, vascular involvement, lymph node sampling, estimated blood loss, intraoperative complications and interventions to address them, specimen names, and specimen orientation. We developed a SOR template for pediatric oncology surgery in LRSs. Consensus for all 21 domains and associated subdomains was achieved using a modified Delphi procedure.

Physicians were most likely to recommend primary medical therapy upon diagnosis of glaucoma. Laser therapy was underutilized where they were available. Physicians were more likely to recommend surgery in severe glaucoma, laser therapy in mild glaucoma, while recommendation of medical therapy did not depend on glaucoma severity. To characterize treatment patterns for newly diagnosed glaucoma in sub-Saharan Africa (SSA). This was a multicenter cross-sectional study of adults newly diagnosed with glaucoma at 27 eye care centers in 10 African countries. In addition to demographic and clinical data, physician treatment recommendations (medication, laser, surgery, or no treatment) were recorded. Statistical analyses were performed using STATA version 14.0. Data from 1201 patients were analyzed. Physicians were most likely to recommend primary medical therapy upon diagnosis of glaucoma (69.4%), with laser (13.2%), surgery (14.9%), and no treatment (2.5%) recommended to the remaining patients. All sites had medical therapy available and most (25/27, 92.6%) could provide surgical treatment; only 16/27 (59.3%) sites offered laser, and at these sites, 30.8% of eyes were recommended to undergo primary laser procedures. As glaucoma severity increased, the laser was recommended less, surgery more, and medications unchanged. Patient acceptance of medical therapy was 99.1%, laser 88.3%, and surgery 69.3%. Medical therapy for first-line glaucoma management is preferred by most physicians in SSA (69%). Laser therapy may be underutilized at centers where it is available. These findings underscore the need for comparative studies of glaucoma treatments in SSA to inform the development of evidence-based treatment guidelines and of programs to reduce glaucoma blindness in SSA. Strategic approaches to glaucoma therapy in SSA must address the question of whether medical therapy is the most optimal first-line approach in this setting.

BackgroundAs part of the global Invasive Bacterial Vaccine-Preventable Diseases Surveillance Network, 12 African countries referred cerebrospinal fluid (CSF) samples to South Africa’s regional reference laboratory. We evaluated the utility of real-time polymerase chain reaction (PCR) in detecting and serotyping/grouping Haemophilus influenzae, Neisseria meningitidis, and Streptococcus pneumoniae (HNS).MethodsFrom 2008 to 2017, CSF samples collected from children <5 years old with suspected meningitis underwent routine microbiology testing in-country, and 11 680 samples were submitted for HNS PCR at the regional reference laboratory. Unconditional logistic regression, with adjustment for geographic location, was performed to identify factors associated with PCR positivity.ResultsThe overall HNS PCR positivity rate for all countries was 10% (1195 of 11 626 samples). In samples with both PCR and culture results, HNS PCR positivity was 11% (744 of 6747 samples), and HNS culture positivity was 3% (207 of 6747). Molecular serotype/serogroup was assigned in 75% of PCR-positive specimens (762 of 1016). Compared with PCR-negative CSF samples, PCR-positive samples were more often turbid (adjusted odds ratio, 6.80; 95% confidence interval, 5.67–8.17) and xanthochromic (1.72; 1.29–2.28), had elevated white blood cell counts (6.13; 4.71–7.99) and high protein concentrations (5.80; 4.34–7.75), and were more often HNS culture positive (32.70; 23.18–46.12).ConclusionPCR increased detection of vaccine-preventable bacterial meningitis in countries where confirmation of suspected meningitis cases is impeded by limited culture capacity.
