Detection of Bacterial Infections and Malaria among Blood Culture-Negative Samples of Hospitalized Febrile Patients from a Tertiary Hospital in Ethiopia

Febrile illnesses contribute significantly to morbidity and mortality in sub-Saharan Africa, but the lack of diagnostic facilities and the broad spectrum of pathogens can lead to inadequate clinical management. The timely and reliable identification of the causative pathogens in febrile patients is the basis for the administration of optimal treatment. We aimed to evaluate the performance of a multiplex polymerase chain reaction (PCR) among blood culture-negative patients presenting with febrile diseases in Central Ethiopia. From April 2016 to June 2018, we collected blood samples from adults and children ≥1 year of age admitted with febrile diseases to the Asella Referral and Teaching Hospital, which is located at an altitude of 2,400 m. Total nucleic acids were extracted from frozen plasma samples using a MagNA Pure 96 instrument (Roche, Mannheim, Germany). The multiplex PCR assays were used in combination with LightCycler multiplex DNA master mix (Roche) on a LightCycler 480 instrument (Roche). We used the pathogen-specific assays targeted to Plasmodium spp., Borrelia spp., Rickettsia spp., Leptospira spp., Salmonella spp., and arboviruses. We tested plasma samples of 511 patients and found positive results for Plasmodium spp. (13, 2.5%), Borrelia spp. (12, 2.3%), and Rickettsia species (7, 1.3%); in total, pathogens were detected in 32 of the samples (6.3%). No pathogen was detected by multiplex PCR in 94% of blood culture-negative samples. Even if the pathogens identified by PCR were not necessarily causes of fever, molecular testing using a multiplex PCR can contribute to pathogen diagnosis in a proportion of febrile patients in the highland part of Ethiopia and help to improve the clinical management.

DISP-07. CURRENT NEURO-ONCOLOGY CAPACITY IN SUB-SAHARAN AFRICAN COUNTRIES: A QUESTIONNAIRE-BASED SURVEY

Abstract Brain tumors constitute significant morbidity and mortality in sub-Saharan Africa (SSA). There is no previous large-scale effort focusing on brain tumor genetics in SSA. This project aims to map out the current neuro-oncology capacity in terms of workforce and available services in SSA. This is an ongoing online survey among a cross section of neuro-oncology practitioners spread across SSA countries to capture information on the distribution, number of available neuro-oncology care practitioners, capacity for neuropathology and molecular diagnosis, management of brain tumors, cancer registration, and tumor biobanking. The survey was disseminated by the Society for Neuro-oncology in SSA (SNOSSA). There were 83 respondents representing 15 countries and 52 health institutions: 46 tertiary, 4 secondary, 1 private and 1 other. Here, we present data on the 52 institutions. The prevalence of specialties was 87% neurosurgery, 75% anatomic pathology, 69% medical oncology, 64% neurology, 60% radiation oncology, and 39% neuropathology. For radiologic evaluation, 81% of institutions were reported to have both CT and MRI, 17% CT only, and one institution neither. For molecular testing, 46% have access to IHC or NGS testing, whereas 52% were reported to have neither. A neuro-oncology tumor board was reported at 58% of institutions. A general cancer registry is available in 64% of institutions, 31% have a brain tumor specific registry and 10% have a brain tumor biorepository. This study shows that SSA has substantial potential in neuro-oncology care practice capacity and facilities. Most significant gaps remain in areas such as neuropathology and molecular testing, which makes widespread implementation of the WHO 2021 diagnosis challenging. Understanding the prevalence of CNS tumor subtypes is also difficult due to low number of brain tumor registries and biobanks in SSA. The present findings reveal strategic opportunities, especially in neuropathology, tumor registries, biobanks, and infrastructure for IHC and NGS in SSA.

Factors influencing antenatal care attendance in the eight contact era policy: a case of selected maternal health service facilities in Blantyre, Malawi

BackgroundMaternal mortality in sub-Saharan Africa and Malawi remains high. Effective antenatal care (ANC) services can reduce maternal morbidity and mortality. However, attendance to ANC clinics and the quality of services provided remain a challenge. Malawi adopted the 2016 WHO antenatal care model and there is a need to assess factors that influence antenatal care attendance. The main objective of this study was to assess factors influencing attendance in the era of the eight ANC contact policy in Blantyre.MethodsThis was an exploratory qualitative design in which 28 respondents participated using in-depth interviews and focus group discussions for the data collection process. The study sites included two healthcare facilities, namely Queen Elizabeth Central Hospital and Bangwe Health Centre, and a rural community (William Village Bangwe Rural) in Blantyre district. The 28 study participants included 11 ANC attendees, which comprised seven women in their final trimester and four postpartum women who attended ANC during their pregnancy, five midwives running the ANC clinics, and 12 non-users of ANC. The recordings were transcribed verbatim. The data were organized using Microsoft Excel and Microsoft word and analyzed using inductive content analysis.ResultsThe factors promoting ANC attendance in the context of the eight ANC contact policy include; motivation from health workers, family, and spouses and the women’s perceptions of ANC particularly the role it plays in preventing, detecting, and treating illness, but also preventing adverse pregnancy outcomes. On the other hand, the hindering factors to ANC attendance included lack of knowledge of the new ANC visit guidelines, financial constraints, quality of health services provided, attitude of healthcare workers, inadequate availability and training of healthcare workers, perceived poor quality of ANC services and personal beliefs.ConclusionIt is essential to provide comprehensive training to healthcare workers in the antenatal department regarding the new WHO ANC recommendations. This will help improve the quality of services at the antenatal clinics, including ensuring the availability of all necessary resources to encourage attendance. Additionally, promoting comprehensive spousal support, encouraging participation in activities, and adequately planning scheduled visits can help overcome financial barriers and further support antenatal attendance.

Rhizomatoflavonoid D and Other Flavonoids from the Twigs of Ochna Rhizomatosa as a Potential Inhibitor of HIV-1

AbstractCurrently, HIV morbidity and mortality in sub-Saharan Africa remain a huge concern and awaiting interventions. Even though the combination antiretroviral therapy (cART) has recorded significant success, drug resistance and limited access to available therapeutics are major factors responsible for the low impact of cART in several African communities. Herein, as part of our continuous effort on the investigation of bioactive metabolites of Ochna rhizomatosa, we report the isolation of a new flavonoid; Rhizomatoflavonoid D (1), alongside with four known ones (2–5). The structures of these compounds were elucidated by using spectroscopic techniques (1H NMR, 13C NMR, HSQC, HMBC, 1H-1H COSY, and ROESY) and mass spectrometry. The antiviral activity of the resulting compounds was assessed using deCIPhR assay run in parallel with the Alamar Blue based cytotoxicity assay. This assay revealed a moderate activity for compound 4 (72% inhibition at 2.5 µg/mL) while compound 1 had minimal activity (36% inhibition at 2.5 µg/mL). The prominent inhibitory effect on HIV-1 was showed by compound 4 (IC50 = 3.1 µM). Unfortunately, compound 4 proved to be non-selective as it demonstrated also a CC50 = 5.2 µg/mL (Selectivity index of 1.7). The prominent inhibitory effect on HIV-1 showed by compound 4 (IC50 = 3.1 µM) could be due the presence of a methoxy group at C-7, since this group enhances the lipophilicity of biflavonoids, thereby improving its incorporation into cells.

OTHR-05 FEASIBILITY STUDY ON BRAIN TUMOR BIOBANKING AND REGISTRY IN SUB-SAHARAN AFRICAN COUNTRIES: A QUESTIONNAIRE-BASED SURVEY

Abstract INTRODUCTION Brain tumors constitute significant morbidity and mortality in sub-Saharan Africa (SSA). Improvements in neuro-oncology practice and research have seen increased diagnosis of brain tumors. However, to our knowledge, there have been no previous projects on brain tumor genetics in SSA. To understand the feasibility of developing brain tumor biobanking and registries, this project aims to start by mapping out the current neuro-oncology capacity in terms of workforce and available services. METHODOLOGY We will conduct a descriptive questionnaire-based online survey among a cross section of neuro-oncology practitioners spread across SSA countries. The dissemination of the survey questionnaire will be facilitated by the Society for Neuro-oncology in SSA (SNOSSA). The Google designed questionnaire will capture information on the distribution, and number of available neuro-oncology care practitioners, capacity for brain tumor diagnosis and management, cancer registration, tumor biobanking, and research. CLINICAL IMPACT AND CONCLUSION This study will generate robust data from SSA, which can be used to improve future research and promote advocacy towards brain tumor diagnosis and management. This work will also serve as a pilot study for subsequent research that will focus on the development of brain tumor-specific registries and biorepositories in SSA.

Spatial distribution of teenage pregnancy and its associated factors in Ethiopia: spatial and multilevel analysis of EDHS 2019

BackgroundOne of the reasons for the high rates of maternal and child morbidity and mortality in Sub-Saharan Africa is the rising proportion of teenage pregnancy. Preventing teenage pregnancy is critical to meeting sustainable development goal number three which aims to reduce the global maternal mortality ratio to less than 70 per 100,000 live births. To support the achievement of this goal, this study aimed to assess the spatial variation and factors associated with teenage pregnancy in Ethiopia using the recent nationally representative data.MethodsA secondary data analysis of the 2019 Ethiopian mini Demographic and Health Survey was conducted with a total weighted sample of 2211 (unweighted 2100) teenagers. The Bernoulli model was fitted using SaTScan version 9.6 to identify hotspot areas and the geospatial pattern and prediction of teenage pregnancy were mapped using ArcGIS version 10.7. A multilevel logistic regression model was fitted to identify factors associated with teenage pregnancy among teenagers. Adjusted OR with 95% CI was calculated and variables having a p-value less than 0.05 were statistically significant factors of teenage pregnancy.ResultThe prevalence of teenage pregnancy among adolescents aged 15–19 years in Ethiopia was 12.89% (95% CI: 11.56%, 14.36%). The SaTScan analysis identified a primary cluster in the Gambella region of Ethiopia (log-likelihood ratio = 14.02, p < 0.001). A high prevalence of teenage pregnancy was observed in Somalia, Afar, Gambella, and the southern part of the Oromia regions of Ethiopia. Age, educational status- primary and secondary, religion- protestant, having television, contraceptive knowledge, household head-female, and region- Small peripheral were significant determinants of teenage pregnancy.ConclusionThe spatial distribution of teenage pregnancy in Ethiopia was nonrandom. Age, educational status, religion, having television, contraceptive knowledge, sex of household head, and region were significant determinants of teenage pregnancy. Therefore, concerned government bodies and other stakeholders should organize periodic educational campaigns and youth-friendly reproductive health services. Collaboration between healthcare professionals, and religious and community leaders could also form a strategic partnership that makes interventions more comprehensive, culturally sensitive, and effective in reducing teenage pregnancy.

Empowering adolescents living with perinatally-acquired HIV: tailored CD4+ count assessment for optimized care, the EDCTP READY-study.

The elevated rate of AIDS-related mortality in Sub-Saharan Africa among adolescents living with HIV (ALHIV) is influenced by various factors, notably immunosuppression, within a framework of limited therapeutic alternatives. We aimed to enhance the management of pediatric HIV by assessing the immune response and associated factors in perinatally-infected ALHIV on antiretroviral therapy (ART) in Cameroon. A cohort study was conducted from 2018-2020 among 271 ART-experienced ALHIV in Cameroon. Sociodemographic data, immunological (CD4), and virological (plasma viral load, PVL) responses were measured at enrolment (T0), 6-months (T1), and 12-months (T2) using PIMA CD4 (Abbott/Pantech (Pty) Ltd) and Abbott Applied Biosystem platform (Real-Time PCR m2000RT) respectively. Immunological failure (IF) was defined as absolute CD4 < 250 cells/mm3, and Virological failure (VF) as PVL ≥ 1,000 copies/ml. A linear mixed-effects model with R version 4.4.1 was used to estimate both fixed and random effects, with significance set at p < 0.05. Of the 271 perinatally-infected ALHIV enrolled over three phases, females were predominant (55.7, 55.1, and 56.0%); median age was 14 (IQR: 12-17); majority of the participants were followed-up in urban areas (77.5, 74.5, and 78.6%); and the age distribution favored older adolescents (48.7, 61.2, and 58.5%). Most participants achieved clinical success (93.1, 89.7, 88.9%), predominantly on first-line ART (80.8, 66.2, and 53.0%), with good adherence (64.2, 58.9, and 64.5%). Most participants had secondary education (67.2, 70.1, and 67.5%). Median CD4+ counts fluctuated overtime, with values of 563 (IQR: 249.0-845.0), 502 (IQR: 319.0-783.5), and 628 (IQR: 427.5-817.5), respectively. Of note, being male was linked to a reduction in CD4+ count compared to females, [-200.63 (-379.32 to -21.95), p = 0.028]. Similarly, late adolescence was associated with lower CD4+ counts compared to early adolescence, [-181.08 (-301.08 to -61.09), p = 0.003]. Moreover, participants experiencing VF showed significantly lower CD4+ counts compared to those with undetectable viral loads, [-353.08 (-465.81 to -240.36), p < 0.001]. Additionally, there was a marginally significant interaction between male gender and secondary educational level, [209.78 (-6.94-426.51), p = 0.058]. Among perinatally-infected ALHIV, age, gender, educational level, and virological status are key factors influencing their immune health and treatment outcomes. Prioritizing targeted interventions and close monitoring within these subgroups is crucial for optimal management, employing holistic care strategies that consider not only medical interventions but also psychosocial support and education.

Bridging the Gap: Immune Checkpoint Inhibitor as an Option in the Management of Advanced and Recurrent Cervical Cancer in Sub-Saharan Africa.

Cervical cancer remains a leading cause of cancer-related mortality in women in low and middle-income countries despite efforts to improve prevention and standard-of-care interventions. Sub-Saharan Africa (SSA) leads the numbers for global cervical cancer incidence and mortality, with the majority of the incidence diagnosed in the late stage of the malignancy. Although the global cervical cancer death rate has been on the decline for the last two decades owing to advancements in screening and treatment options, the mortality rate in SSA has not declined very much. Chemotherapy has been the treatment of choice for cervical cancer in SSA without meeting the expected survival outcomes in these patients, with the majority having advanced diseases at diagnosis. Immune checkpoint inhibitors have recently shown clinical promise in improving the survival of patients with advanced cervical cancer and have been integrated into the treatment guidelines in most high-income countries, which have helped further reduce the mortality rate of cervical cancer. However, many SSA countries are yet to fully benefit from using immune checkpoint inhibitors in cervical cancer. In this review, we discuss the challenges hindering the effective use of immune checkpoint inhibitors for advanced cervical cancer in Africa and possible solutions.

First Results From a Calibrated Network of Low-Cost PM2.5 Monitors in Mombasa, Kenya Show Exceedance of Healthy Guidelines.

The paucity of fine particulate matter (PM2.5) measurements limits estimates of air pollution mortality in Sub-Saharan Africa. Well calibrated low-cost sensors can provide reliable data especially where reference monitors are unavailable. We evaluate the performance of Clarity Node-S PM monitors against a Tapered element oscillating microbalance (TEOM) 1400a and develop a calibration model in Mombasa, Kenya's second largest city. As-reported Clarity Node-S data from January 2023 through April 2023 was moderately correlated with the TEOM-1400a measurements (R 2=0.61) and exhibited a mean absolute error (MAE) of 7.03μgm-3. Employing three calibration models, namely, multiple linear regression (MLR), Gaussian mixture regression and random forest (RF) decreased the MAE to 4.28, 3.93, and 4.40μgm-3 respectively. The R 2 value improved to 0.63 for the MLR model but all other models registered a decrease (R 2=0.44 and 0.60 respectively). Applying the correction factor to a five-sensor network in Mombasa that was operated between July 2021 and July 2022 gave insights to the air quality in the city. The average daily concentrations of PM2.5 within the city ranged from 12 to 18μgm-3. The concentrations exceeded the WHO daily PM2.5 limits more than 50% of the time, in particular at the sites nearby frequent industrial activity. Higher averages were observed during the dry and cold seasons and during early morning and evening periods of high activity. These results represent some of the first air quality monitoring measurements in Mombasa and highlight the need for more study.

Azithromycin to Reduce Mortality — An Adaptive Cluster-Randomized Trial

BackgroundTwice-yearly mass distribution of azithromycin to children is a promising intervention to reduce childhood mortality in sub-Saharan Africa. The World Health Organization recommended restricting distribution to infants 1 to 11 months of age to mitigate antimicrobial resistance, although this more limited treatment had not yet been tested.MethodsWe randomly assigned rural communities in Niger to four twice-yearly distributions of azithromycin for children 1 to 59 months of age (child azithromycin group), four twice-yearly distributions of azithromycin for infants 1 to 11 months of age and placebo for children 12 to 59 months of age (infant azithromycin group), or placebo for children 1 to 59 months of age. Census workers who were not aware of the group assignments monitored mortality twice yearly over the course of 2 years. We assessed three primary community-level mortality outcomes (deaths per 1000 person-years), each examining a different age group and pairwise group comparison.ResultsA total of 1273 communities were randomly assigned to the child azithromycin group (1229 were included in the analysis), 773 to the infant azithromycin group (751 included in the analysis), and 954 to the placebo group (929 included in the analysis). Among 382,586 children, 419,440 person-years and 5503 deaths were recorded. Lower mortality among children 1 to 59 months of age was observed in the child azithromycin group (11.9 deaths per 1000 person-years; 95% confidence interval [CI], 11.3 to 12.6) than in the placebo group (13.9 deaths per 1000 person-years; 95% CI, 13.0 to 14.8) (representing 14% lower mortality with azithromycin; 95% CI, 7 to 22; P<0.001). Mortality among infants 1 to 11 months of age was not significantly lower in the infant azithromycin group (22.3 deaths per 1000 person-years; 95% CI, 20.0 to 24.7) than in the placebo group (23.9 deaths per 1000 person-years; 95% CI, 21.6 to 26.2) (representing 6% lower mortality with azithromycin; 95% CI, −8 to 19). Five serious adverse events were reported: three in the placebo group, one in the infant azithromycin group, and one in the child azithromycin group.ConclusionsAzithromycin distributions to children 1 to 59 months of age significantly reduced mortality and was more effective than treatment of infants 1 to 11 months of age. Antimicrobial resistance must be monitored. (Funded by the Bill and Melinda Gates Foundation; AVENIR ClinicalTrials.gov number, NCT04224987.)

Under-Five Mortality and Associated Risk Factors in Children Hospitalized at David Bernardino Pediatric Hospital (DBPH), Angola: A Hierarchical Approach.

Reducing under-five mortality is a crucial indicator of overall development in a country. However, in Angola, understanding the factors contributing to hospital deaths in this vulnerable demographic remains incomplete despite improvements in healthcare infrastructure and public health policies. With one of the highest under-five mortality rates in sub-Saharan Africa, Angola faces significant challenges such as malaria, malnutrition, pneumonia, neonatal conditions, and intestinal infectious diseases, which are the leading causes of death among children. This study aimed to identify factors associated with hospital deaths among children aged 28 days to five years admitted to DBPH in Luanda between May 2022 and June 2023. Using a hospital-based case-control design, the study included 1020 children, among whom 340 experienced hospital deaths. Distal and intermediate determinants emerged as primary predictors of hospital mortality, showing significant associations with: mother without schooling (OR [95%CI] 4.3 [1.2-15.7], p < 0.027); frequent alcohol consumption during pregnancy (OR [95%CI] 3.8 [2.5-5.9], p < 0.001); hospital stay ≤24 h (OR [95%CI] 13.8 [6.2-30.8], p < 0.001); poor nutritional status (OR [95%CI] 2.1 [1.4-3.2], p < 0.001); short interbirth interval (OR [95%CI] 1.7 [1.1-2.5], p < 0.014); maternal age ≤19 years (OR [95%CI] 5.6 [3.0-10.8], p < 0.001); and maternal age ≥35 years (OR [95%CI] 2.1 [1.2-3.7], p < 0.006). These findings highlight the preventable nature of most under-five hospital deaths and underscore the urgent need to address social inequities and improve the quality of primary healthcare services to effectively reduce child mortality in Angola.

Drug-induced hepatotoxicity and association with slow acetylation variants NAT2*5 and NAT2*6 in Cameroonian patients with tuberculosis and HIV co-infection

BackgroundHuman immunodeficiency virus (HIV) and tuberculosis (TB) are major contributors to morbidity and mortality in sub-Saharan Africa including Cameroon. Pharmacogenetic variants could serve as predictors of drug-induced hepatotoxicity (DIH), in patients with TB co-infected with HIV. We evaluated the occurrence of DIH and pharmacogenetic variants in Cameroonian patients.MethodsTreatment-naïve patients with HIV, TB or TB/HIV co-infection were recruited at three hospitals in Cameroon, between September 2018 and November 2019. Appropriate treatment was initiated, and patients followed up for 12 weeks to assess DIH. Pharmacogenetic variants were assessed by allele discrimination TaqMan SNP assays.ResultsOf the 141 treatment naïve patients, the overall incidence of DIH was 38% (53/141). The highest incidence of DIH, 52% (32/61), was observed among HIV patients. Of 32 pharmacogenetic variants, the slow acetylation variants NAT2*5 was associated with a decreased risk of DIH (OR: 0.4; 95%CI: 0.17–0.96; p = 0.038), while NAT2*6 was found to be associated with an increased risk of DIH (OR: 4.2; 95%CI: 1.1–15.2; p = 0.017) among patients treated for TB. Up to 15 SNPs differed in ≥ 5% of allele frequencies among African populations, while 25 SNPs differed in ≥ 5% of the allele frequencies among non-African populations, respectively.ConclusionsDIH is an important clinical problem in African patients with TB and HIV. The NAT2*5 and NAT2*6 variants were found to be associated with DIH in the Cameroonian population. Prior screening for the slow acetylation variants NAT2*5 and NAT2*6 may prevent DIH in TB and HIV-coinfected patients.

Modeling the Impact of Proactive Community Case Management on Reducing Confirmed Malaria Cases in Sub-Saharan African Countries.

Malaria continues to be a major source of morbidity and mortality in sub-Saharan Africa. Timely, accurate, and effective case management is critical to malaria control. Proactive community case management (ProCCM) is a new strategy in which a community health worker "sweeps" a village, visiting households at defined intervals to proactively provide diagnostic testing and treatment if indicated. Pilot experiments have shown the potential of ProCCM for controlling malaria transmission; identifying the best strategy for administering ProCCM in terms of interval timings and number of sweeps could lead to further reductions in malaria infections. We developed an agent-based simulation to model malaria transmission and the impact of various ProCCM strategies. The model was validated using symptomatic prevalence data from a ProCCM pilot study in Senegal. Various ProCCM strategies were tested to evaluate the potential for reducing parasitologically confirmed symptomatic malaria cases in the Senegal setting. We found that weekly ProCCM sweeps during a 21-week transmission season could reduce cases by 36.3% per year compared with no sweeps. Alternatively, two initial fortnightly sweeps, seven weekly sweeps, and finally four fortnightly sweeps (13 sweeps total) could reduce confirmed malaria cases by 30.5% per year while reducing the number of diagnostic tests and corresponding costs by about 33%. Under a highly seasonal transmission setting, starting the sweeps early with longer duration and higher frequency would increase the impact of ProCCM, though with diminishing returns. The model is flexible and allows decision-makers to evaluate implementation strategies incorporating sweep frequency, time of year, and available budget.

Evaluating diabetes care in primary healthcare centers in Abuja, Nigeria: a cross-sectional formative assessment

IntroductionNoncommunicable diseases (NCDs) are associated with high and rising burden of morbidity and mortality in sub-Saharan Africa, including Nigeria. Diabetes mellitus (DM) is among the leading causes of NCD-related deaths worldwide and is a foremost public health problem in Nigeria. As part of National policy, Nigeria has committed to implement the World Health Organization (WHO) Package of Essential Non-communicable Disease interventions for primary care. Implementing the intervention requires the availability of essential elements, including guidelines, trained staff, health management information systems (HMIS), equipment, and medications, in primary healthcare centers (PHCs). This study assessed the availability of the DM component of the WHO package, and the readiness of the health workers in these PHCs to implement a DM screening, evaluation, and management program to inform future adoption and implementation.MethodsThis cross-sectional formative assessment adapted the WHO Service Availability and Readiness Assessment (SARA) tool to survey 30 PHCs selected by multistage sampling for readiness to deliver DM diagnosis and care in Abuja, Nigeria, between August and October 2021. The SARA tool was adapted to focus on DM services and the availability and readiness indicator scores were calculated based on the proportion of PHCs with available DM care services, minimum staff requirement, diagnostic tests, equipment, medications, and national guidelines/protocols for DM care within the defined SARA domain.ResultsAll 30 PHCs reported the availability of at least two full-time staff (median [interquartile range] = 5 [4–9]), which were mostly community health extension workers (median [interquartile range]) = 3 [1–4]. At least one staff member was recently trained in DM care in 11 PHCs (36%). The study also reported high availability of paper-based HMIS (100%), and DM screening services using a glucometer (87%), but low availability of DM job aids (27%), treatment (23%), and national guidelines/protocols (0%).ConclusionThis formative assessment of PHCs’ readiness to implement a DM screening, evaluation, and management program in Abuja demonstrated readiness to integrate DM care into PHCs regarding equipment, paper-based HMIS, and nonphysician health workers' availability. However, strategies are needed to promote DM health workforce training, provide DM management guidelines, and supply essential DM medications.

Population modifiable risk factors associated with neonatal mortality in 35 sub-Saharan Africa countries: analysis of data from demographic and health surveys

Sub-Saharan Africa (SSA) has the highest burden of neonatal mortality in the world. Identifying the most critical modifiable risk factors is imperative for reducing neonatal mortality rates. This study is the first to calculate population-attributable fractions (PAFs) for modifiable risk factors of neonatal mortality in SSA. We analysed the most recent Demographic and Health Surveys data sets from 35 SSA countries conducted between 2010 and 2022. Generalized linear latent and mixed models were used to estimate odds ratios (ORs) along with 95% confidence intervals (CIs). PAFs adjusted for communality were calculated using ORs and prevalence estimates for key modifiable risk factors. Subregional analyses were conducted to examine variations in modifiable risk factors for neonatal mortality across Central, Eastern, Southern, and Western SSA regions. In this study, we included 255,891 live births in the five years before the survey. The highest PAFs of neonatal mortality among singleton children were attributed to delayed initiation of breastfeeding (>1h after birth: PAF=23.88%; 95% CI: 15.91, 24.86), uncleaned cooking fuel (PAF=5.27%; 95% CI: 1.41, 8.73), mother's lacking formal education (PAF=4.34%; 95% CI: 1.15, 6.31), mother's lacking tetanus vaccination (PAF=3.54%; 95% CI: 1.55, 4.92), and infrequent antenatal care (ANC) visits (PAF=2.45; 95% CI: 0.76, 3.63). Together, these five modifiable risk factors were associated with 39.49% (95% CI: 21.13, 48.44) of neonatal deaths among singleton children in SSA. Our subregional analyses revealed some variations in modifiable risk factors for neonatal mortality. Notably, delayed initiation of breastfeeding consistently contributed to the highest PAFs of neonatal mortality across all four regions of SSA: Central, Eastern, Southern, and Western SSA. The PAF estimates in the present study indicate that a considerable proportion of neonatal deaths in SSA are preventable. We identified five modifiable risk factors that accounted for approximately 40% of neonatal deaths in SSA. The findings have policy implications. None.

Assessment of Neonatal Mortality amongst Sick Neonates in the Special Care Baby Unit of a Tertiary Institution in Orlu, Nigeria

Introduction: Neonatal mortality constitutes more than 41% of under 5 mortality in sub-Saharan Africa, despite advancement in technology and concerted effort aimed at decreasing under-five mortality. This study aims at assessing the risk factors and causes of neonatal mortality among sick infants in the special care baby unit (SCBU); focused at identification of possible areas of improvement in care and result. Methods: A retrospective review of medical records of sick neonates admitted into SCBU of Imo State University Teaching Hospital Orlu. Sociodemographic and clinical characteristics of 214 sick neonates that died was obtained out of the 948 admitted/treated over a five year period (2018-2022). Descriptive statistics was used to summarize data, logistic regression at 95% level of significance was used to determine association between independent variables and neonatal death. Values of p &lt; 0.05 were considered significant. Results: A total of 948 sick neonates were admitted into SCBU, with a neonatal mortality rate of 22.6%. Complications of prematurity 78 (36.7%), severe birth asphyxia 63(29.6%) and neonatal sepsis 31(14.6%) are the leading causes of death with majority of death occurring in the first 24 hours of life 130(60.8%). Low birth weight [OR=2.59 (95% CI 1.84-3.54)], prematurity [OR=2.79 (95% CI 2.03-3.83)] and spontaneous vaginal deliveries [OR=1.85 (95% CI 1.32-2.60)] were positively associated with increased mortality. While Caesarean section as mode of delivery [OR=0.54 (95% CI 0.38-0.76)] and birth weight &gt;2.5-4.0kg [OR=0.46 (95% CI 0.34-0.64)] significantly reduced neonatal mortality. Conclusion: Neonatal mortality rate is still unacceptably high, with complications of prematurity, severe birth asphyxia and neonatal sepsis contributing the highest percentage of poor outcome (death). Low birth weight, prematurity, and spontaneous vaginal deliveries were positively associated with increased mortality. Multidisciplinary measures aimed at reduction of neonatal morbidity and mortality such as improving the utilization of antenatal care services, quality of care at delivery, at the neonatal intensive care unit needs be strengthened.

Stroke care in sub-Saharan Africa: Evaluating the present landscape and proposing strategies for improving outcomes

The burden of stroke is alarmingly high in sub-Saharan Africa (SSA), characterized by increasing trends in stroke incidence, prevalence, and mortality. This review details the landscape of stroke care in SSA, encompassing epidemiology, risk factors, care availability, and challenges in advancing stroke care, along with a proposed strategic framework for improvement. Epidemiological studies in SSA indicate a rising trend in stroke incidence and prevalence, with significant variability attributable to differences in study methodologies. Crude incidence rates have risen from an average of 53 (range: 26 &amp;ndash; 101) cases/100,000 population between 1973 and 1991 to 88 (range: 25 &amp;ndash; 149) cases/100,000 population between 2003 and 2011. Similarly, prevalence rates have shown an upward trend. Stroke mortality in SSA remains high, with variability across studies. Key predictors of mortality include hemorrhagic stroke, gender, National Institute of Stroke Scale score at presentation, and comorbidities such as anemia and human immunodeficiency virus infection. However, the interpretation of mortality rates warrants caution due to methodological limitations. Both modifiable and non-modifiable risk factors significantly contribute to stroke risk in SSA. Notably, stroke occurs at a younger age in SSA compared to Western countries. Hypertension, diabetes, dyslipidemia, and lifestyle factors are among the major modifiable risk factors. The availability of organized stroke care varies significantly across SSA, with more advanced care typically found in higher-level health-care centers. However, efforts to improve access and quality of care are ongoing. The challenges in advancing stroke care in SSA include cultural beliefs, limited access to care, and prohibitive costs. A &amp;ldquo;5 Ps&amp;rdquo; framework involving collaboration among policymakers, payers, partners in health care, providers, and patients is proposed to improve stroke care. This review underscores the urgent need for enhanced public health strategies, medical interventions, and collaborative efforts to address the escalating stroke burden in SSA.
