Neisseria meningitidis is the commonest cause of meningitis outbreaks; Streptococcus pneumoniae and Haemophilus influenzae causes. B Background: b Outbreaks of meningitis occur periodically in Nigeria, with the northern parts mostly affected. The increasing incidence of Neisseria meningitidis X is worrisome, because the reactive and preventive vaccination for meningitis does not cover this serogroup, countries in the African meningitis belt must prepare to face this potential new challenge.

Background: The blended learning (BL) approach to training health care professionals is increasingly adopted in many countries because of high costs and disruption to service delivery in the light of severe human resource shortage in low resource settings. The Covid-19 pandemic increased the urgency to identify alternatives to traditional face-to-face (f2f) education approach. A four-day f2f antenatal care (ANC) and postnatal care (PNC) continuous professional development course (CPD) was repackaged into a 3-part BL course; (1) self-directed learning (16 h) (2) facilitated virtual sessions (2.5 h over 3 days) and (3) 2-day f2f sessions. This study assessed the feasibility, change in healthcare providers' knowledge and costs of the BL package in Nigeria, Tanzania, and Kenya., Methods: A mixed methods design was used. A total of 89 healthcare professionals, were purposively selected. Quantitative data was collected through an online questionnaire and skills assessments, analyzed using STATA 12 software. Qualitative data was collected through key informant interviews and focus group discussions, analysed using thematic analysis., Results: Majority of participants (86%) accessed the online sessions using a mobile phone from home and health facilities. The median (IQR) time of completing the self-directed component was 16 h, IQR (8, 30). A multi-disciplinary team comprising of 42% nurse-midwives, 28% doctors, 20% clinical officers and 10% other healthcare professionals completed the BL course. Participants liked the BL approach due to its flexibility in learning, highly educative/relevant content, mixing of health worker cadres and CPD points. Aspects that were noted as challenging were related to personal log-in details and network connectivity issues during the self-directed learning and facilitated virtual sessions respectively., Conclusion: The blended learning approach to ANC-PNC in-service training was found to be acceptable, feasible and cost less to implement compared to face-to-face training approach in the study settings. The BL training approach was effective in improving the knowledge and skills of healthcare providers who participated in the training., Competing Interests: Declarations.

Background: Midwifery education is under-invested in developing countries with limited opportunities for midwifery educators to improve/maintain their core professional competencies. To improve the quality of midwifery education and capacity for educators to update their competencies, a blended midwifery educator-specific continuous professional development (CPD) programme was designed with key stakeholders. This study evaluated the feasibility of this programme in Kenya and Nigeria., Methods: This was a mixed methods intervention study using a concurrent nested design. 120 randomly selected midwifery educators from 81 pre-service training institutions were recruited. Educators completed four self-directed online learning (SDL) modules and three-day practical training of the blended CPD programme on teaching methods (theory and clinical skills), assessments, effective feedback and digital innovations in teaching and learning. Pre- and post-training knowledge using multiple choice questions in SDL; confidence (on a 0-4 Likert scale) and practical skills in preparing a teaching a plan and microteaching (against a checklist) were measured. Differences in knowledge, confidence and skills were analysed. Participants' reaction to the programme (relevance and satisfaction assessed on a 0-4 Likert scale, what they liked and challenges) were collected. Key informant interviews with nursing and midwifery councils and institutions' managers were conducted. Thematic framework analysis was conducted for qualitative data., Results: 116 (96.7%) and 108 (90%) educators completed the SDL and practical components respectively. Mean knowledge scores in SDL modules improved from 52.4% (± 10.4) to 80.4% (± 8.1), preparing teaching plan median scores improved from 63.6% (IQR 45.5) to 81.8% (IQR 27.3), and confidence in applying selected pedagogy skills improved from 2.7 to 3.7, p < 0.001. Participants rated the SDL and practical components of the programme high for relevance and satisfaction (median, 4 out of 4 for both). After training, 51.4% and 57.9% of the participants scored 75% or higher in preparing teaching plans and microteaching assessments. Country, training institution type or educator characteristics had no significant associations with overall competence in preparing teaching plans and microteaching (p > 0.05). Qualitatively, educators found the programme educative, flexible, convenient, motivating, and interactive for learning. Internet connectivity, computer technology, costs and time constraints were potential challenges to completing the programme., Conclusion: The programme was feasible and effective in improving the knowledge and skills of educators for effective teaching/learning. For successful roll-out, policy framework for mandatory midwifery educator specific CPD programme is needed., (© 2024. The Author(s).)

Background: Influenza is a leading cause of morbidity and mortality globally. Little is known of the true burden and epidemiology of influenza in Africa. Nigeria has a sentinel surveillance system for influenza virus (IFV). This study seeks to describe the epidemiological characteristics of influenza cases in Nigeria through secondary data analysis of the sentinel surveillance data from 2010 to 2020., Methodology: A retrospective secondary data analysis of data collected from patients with influenza-like illness (ILI) and severe acute respiratory infection (SARI) in the four Nigeria Influenza Sentinel Surveillance sites from January 2010 to December 2020. Data was cleaned and analyzed using Microsoft Excel and Epi info 7.2 for frequencies and proportions. The results of the analysis were summarized in tables and charts., Results: A total of 13,828 suspected cases of influenza were recorded at the sentinel sites during the study period. About 10.3% (1421/13,828) of these tested positive for IFV of which 1243 (87.5%) were ILI patients, 175 (12.3%) SARI patients, and 3 (0.2%) novel H1N1 patients. Males accounted for 54.2% (770/1421) of the confirmed cases. The median age of confirmed cases was 3 years (range: <1month-97 years). Children 0-4 years accounted for 69.3% (985/1421) of all cases. The predominant subtypes were B lineage not determined (32.3%), A/H1N1 pdm09 (28.8%) and A/H3 (23.0%). There were periods of sustained transmission in most years with 2011 having the highest number of cases. Overall, there were more cases around January to March and August to November. Heart disease and chronic shortness of breath were the most common co-morbidities identified among confirmed cases., Conclusion: Influenza remains a significant cause of respiratory illness, especially among children aged less than 4 years. Influenza cases occur all year round with irregular seasonality in Nigeria. Children less than 4 years and those with co-morbidities should be prioritized for vaccination. Vaccine composition in the country should take cognizance of the prevailing strains which are type B (lineage not determined), A/H1N1 pdm09 and A/H3., Competing Interests: Declaration of Competing Interest I declare that this manuscript is original and has not been published before. It is not currently being considered for publication elsewhere. No financial support was received for this study. As the corresponding author, I have approved the final version of the manuscript and agree to be accountable for all aspects of this work., (Copyright © 2024 The Authors. Published by Elsevier Ltd..

Introduction: Prompt access to emergency obstetrical care (EmOC) reduces the risk of maternal mortality. We assessed institutional maternal mortality by distance and travel time for pregnant women with obstetrical emergencies in Lagos State, Nigeria., Methods: We conducted a facility-based retrospective cohort study across 24 public hospitals in Lagos. Reviewing case notes of the pregnant women presenting between 1 November 2018 and 30 October 2019, we extracted socio-demographic, travel and obstetrical data. The extracted travel data were exported to Google Maps, where driving distance and travel time data were extracted. Multivariable logistic regression was conducted to determine the relative influence of distance and travel time on maternal death., Findings: Of 4181 pregnant women with obstetrical emergencies, 182 (4.4%) resulted in maternal deaths. Among those who died, 60.3% travelled ≤10 km directly from home, and 61.9% arrived at the hospital ≤30 mins. The median distance and travel time to EmOC was 7.6 km (IQR 3.4-18.0) and 26 mins (IQR 12-50). For all women, travelling 10-15 km (2.53, 95% CI 1.27 to 5.03) was significantly associated with maternal death. Stratified by referral, odds remained statistically significant for those travelling 10-15 km in the non-referred group (2.48, 95% CI 1.18 to 5.23) and for travel ≥120 min (7.05, 95% CI 1.10 to 45.32). For those referred, odds became statistically significant at 25-35 km (21.40, 95% CI 1.24 to 36.72) and for journeys requiring travel time from as little as 10-29 min (184.23, 95% CI 5.14 to 608.51). Odds were also significantly higher for women travelling to hospitals in suburban (3.60, 95% CI 1.59 to 8.18) or rural (2.51, 95% CI 1.01 to 6.29) areas., Conclusion: Our evidence shows that distance and travel time influence maternal mortality differently for referred women and those who are not. Larger scale research that uses closer-to-reality travel time and distance estimates as we have done, rethinking of global guidelines, and bold actions addressing access gaps, including within the suburbs, will be critical in reducing maternal mortality by 2030., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

The origin, tissue concentration, and health risk of polycyclic aromatic hydrocarbons (PAHs) contaminants in three economically important species of seafood, including catfish ( Chrysichthys nigrodigitatus ), prawns ( Macrobrachium macrobrachium ), and periwinkles ( Tympanotonus fuscatus ) from the crude oil-impacted Niger Delta region, were investigated. The concentrations of PAHs were measured by coupled gas chromatography-mass spectrometry after repeated extraction by ultrasonication in hexane and cleaning up in silica gel. The origin of PAHs was deduced using established mathematical protocols. Health risk from the consumption of contaminated seafood was evaluated for 60 kg bodyweight individuals at a fish consumption rate of 36.94 g per person per day. Different tissue concentrations of PAHs residues at low, moderate, and chronic levels were revealed. Mean total PAHs varied from 4.55 to 6.36 mg kg -1 in catfish, 4.61 to 7.75 mg kg -1 in prawns, and 4.91 to 6.14 mg kg -1 in periwinkles. The tissue concentrations were high above PM 2.5 , enough to suspect PAHs-related health risk, especially among residents who consume a large quantity of seafood. Carcinogenic PAHs index, benzo[ a ]pyrene, varied from below instrument detection (<0.01) to 0.29 mg kg -1 . The estimated carcinogenic potency equivalent concentrations (PEC) of PAH varied from 0.653 to 2.153 above the screening value (SV), 0.01624 in the three species investigated. Mathematical evaluation and dominant tissue concentration of high molecular weight PAHs in all the seafood investigated showed pyrogenic origin of PAHs.

The global COVID-19 pandemic is predicted to compromise the achievement of global reproductive, maternal, and newborn health (RMNH) targets. The objective of this study was to determine the health facility (HF) preparedness for RMNH service delivery during the outbreak from the perspective of RMNH providers and to determine what factors significantly predict this. An anonymous cross-sectional online survey of RMNH providers was conducted from to July 1-21, 2020 in Lagos State, Nigeria. We conducted a descriptive and ordinal regression analysis, with RMNH worker perception of HF preparedness for RMNH service delivery during the outbreak as the dependent variable. In all, 256 RMNH workers participated, 35.2% reported that RMNH services were unavailable at some time since March 2020, 87.1% felt work-related burnout, 97.7% were concerned about the availability of personal protective equipment (PPE) and related guidelines, and only 11.7% were satisfied with the preparedness of their HFs. Our final model was a statistically significant predictor of RMNH worker perception of HF preparedness explaining 54.7% of the variation observed. The most significant contribution to the model was communication by HF management (likelihood ratio chi-square [LRCS]: 87.94, P < 0.001) and the availability of PPE and COVID-19 guidelines (LRCS: 15.43, P < 0.001). A one-unit increase in the level of concern about the availability of PPE and COVID-19 guidelines would increase the odds of observing a higher category of satisfaction with HF COVID-19 preparedness. Adequate support of RMNH providers, particularly provision of PPE and guidelines, and appropriate communications about COVID-19 should be prioritized as part of HF preparedness.

Background: Globally, an estimate of 254,928 measles cases in 2015 and 89,780 deaths in 2016 occur annually. In Nigeria, measles is the fifth leading causes of under-five child mortality with 342 confirmed cases found in the first 9 epidemic weeks in some states including Osun State. We described the distribution, trend and make projection of measles cases in Osun State., Methods: The Osun State surveillance weekly reporting data on measles cases from all its 30 Local Government Area (LGA) were reviewed, from January 2016 to December 2018 (n = 1205). Data were analyzed using descriptive statistics and a multiplicative time series model (MTSM). The MTSM was used to determine the trend, seasonality in the data and make projections for 2019 and 2020., Results: Cases of measles were reported across the 30 LGAs of the state between January 2016 and December 2018. The rate of reported cases of measles was 20.2, 34.4 and 28.8 per 100,000 populations in 2016, 2017 and 2018 respectively in Ede south LGA where the highest rates were reported in the 3-year period. Out of the three studied years, year 2017, recorded the highest number of reported cases of measles in Osun State. The trend line for the 3-year period showed a positive correlation (r = + 0.4979, p = 0.056). The computed quarterly variation for the studied years was 1.094 for the 1st quarter, 1.162 for the 2nd quarter, 0.861 for the 3rd quarter and 0.888 for the 4th quarter. A quarterly projection for 2019 and 2020 showed an increasing trend with the second quarter of each year likely to have the highest reported cases of measles., Conclusions: Ede south LGA has the highest proportion of reported measles cases in Osun State. Measles cases may increase in years ahead, but the second quarter of a year has the highest number. Government should strengthen the existing framework on measles reduction and more attention should be given to the second quarter of each year.

Background: This study was carried out to study the demographic variables, treatment options and mortality in cases of abortion related pelvic abscess., Methods: A retrospective study of patients that had pelvic abscess as a complication of unsafe abortion. The retrieved case files were scrutinized for the necessary information., Result: The age ranged from thirteen years to forty six years, and teenagers accounted for 24.3% of the patients. About half of the patients, 51.4% were childless and parity ranged from zero to eight. The abortionists were mainly untrained personnel and the contraceptive prevalence rate was low, 5.4%. Most of the patient had conservative surgery and a significant number 94.6%, had blood transfusion. Maternal death of 18.9% was recorded with infection being the major cause., Conclusion: Unsafe abortion and its attendant complication is still a problem in Nigeria. High quality post abortion care will help a long way in saving many lives.
