Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Phyllanthus muellerianus (Kunze) Exell, a member of the Phyllanthaceae family, is a medicinal plant widely distributed in Africa. Decoctions from the leaves are used in Nigeria to treat fevers, convulsions, some neurological disorders and malaria. AIM OF THE STUDY This study is to evaluate the anti-malarial properties of methanol extract of Phyllanthus muellerianus (MEPM) leaves and its ethyl acetate fraction using a murine malaria model infected with Plasmodium berghei. Additionally, we seek to investigate the potential modulatory effects of this extract and fraction on CD4+ T-cell populations in the context of malaria infection. MATERIALS AND METHODS The anti-malarial effects of the leaf methanol extract of Phyllanthus muellerianus (MEPM) were screened using three established in vivo models of anti-plasmodial screening namely the curative, suppressive and prophylactic models. The methanol extract (MEPM) was afterwards fractionated into hexane (HFPM), ethyl acetate (EAFPM), and methanol (MFPM) fractions. In the pilot anti-malarial screening of the fractions, EAFPM exhibited the best antiparasitic activity. Subsequently, EAFPM was screened for anti-malarial activity using the three models above. The effects of the MEPM and EAFPM on haematological indices (Hb and PCV) of the inoculated animals were further screened and the mean survival time (MST) of the animals was monitored. CD4+ T cells of various groups were counted before and after treatment using a flow cytometer. The EAFPM was further subjected to HPLC analysis for identification of its major compounds. RESULTS The EAFPM (100 and 200 mg/kg) elicited 88% and 93% cure respectively in the curative model, while artesunate (5 mg/kg,- the positive control) gave 87% protection. The MEPM and EAFPM also gave significant suppression of parasitemia in the suppressive model. The treated groups survived beyond 28 days as against 11 days by the control group (infected but not treated). The treated groups also prevented anaemia seen in the negative control. The EAFPM group significantly modulated the CD4+ T cell. Compounds identified were Gallocatechin, Quercetin -3-O-gallate, Ellagic acid, and Methylellagic acid rhamnoside). CONCLUSION The study established that the leaf of Phyllanthus muellerianus possesses antimalarial activity, thus lending support to its use in the folkloric treatment of malaria.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achyranthes ferruginea (A. ferruginea) Roxb. is a common plant used in traditional medicine in Asia and Africa. It has a variety of local names, including "Gulmanci" in Nigeria, "Dangar" in Pakistan, "Thola" in Ethiopia, and "Roktoshirinchi" in Bangladesh. It is edible and has several ethnomedical uses for a wide range of illnesses, including hysteria, dropsy, constipation, piles, boils, asthma, and shigellosis. However, the neuropharmacological and analgesic potential of A. ferruginea remains uninvestigated. AIM OF THE STUDY To assess the neuropharmacological and analgesic potential of A. ferruginea through a multifaceted approach encompassing both experimental and computational models. MATERIALS AND METHODS Methanol was used to extract the leaves of A. ferruginea. It was then fractionated with low to high polar solvents (n-hexane, chloroform, ethyl acetate, and water) to get different fractions, including chloroform fraction (CLF). The study selected CLF at different doses and conducted advanced chemical element and proximate analyses, as well as phytochemical profiling using GC-MS. Toxicological studies were done at 300 μg per rat per day for 14 days. Cholinesterase inhibitory potential was checked using an in-vitro colorimetric assay. Acetic acid-induced writhing (AAWT) and formalin-induced licking tests (FILT) were used to assess anti-nociceptive effects. The forced swim test (FST), tail suspension test (TST), elevated plus maze (EPM), hole board test (HBT), and light and dark box test (LDB) were among the behavioral tests used to assess depression and anxiolytic activity. Network pharmacology-based analysis was performed on selected compounds using the search tool for interacting chemicals-5 (STITCH 5), Swiss target prediction tool, and search tool for the retrieval of interacting genes and proteins (STRING) database to link their role with genes involved in neurological disorders through gene ontology and reactome analysis. RESULTS Qualitative chemical element analysis revealed the presence of 15 elements, including Na, K, Ca, Mg, P, and Zn. The moisture content, ash value, and organic matter were found to be 11.12, 11.03, and 88.97%, respectively. GC-MS data revealed that the CLF possesses 25 phytoconstituents. Toxicological studies suggested the CLF has no effects on normal growth, hematological and biochemical parameters, or cellular organs after 14 days at 300 μg per rat. The CLF markedly reduced the activity of both acetylcholinesterase and butyrylcholinesterase (IC50: 56.22 and 13.22 μg/mL, respectively). Promising dose-dependent analgesic activity (p < 0.05) was observed in chemically-induced pain models. The TST and FST showed a dose-dependent substantial reduction in immobility time due to the CLF. Treatment with CLF notably increased the number of open arm entries and time spent in the EPM test at doses of 200 and 400 mg/kg b.w. The CLF showed significant anxiolytic activity at 200 mg/kg b.w. in the HBT test, whereas a similar activity was observed at 400 mg/kg b.w. in the EPM test. A notable increase in the amount of time spent in the light compartment was observed in the LDB test by mice treated with CLF, suggesting an anxiolytic effect. A network pharmacology study demonstrated the relationship between the phytochemicals and a number of targets, such as PPARA, PPARG, CHRM1, and HTR2, which are connected to the shown bioactivities. CONCLUSIONS This study demonstrated the safety of A. ferruginea and its efficacy in attenuating cholinesterase inhibitory activity, central and peripheral pain, anxiety, and depression, warranting further exploration of its therapeutic potential.

Abstract
AIM Implementing the Baby-Friendly Hospital Initiative (BFHI) programme has been fraught with challenges globally. The study aimed to assess the implementation of the BFHI and breastfeeding practices in healthcare facilities in Ogun State, Nigeria. METHODS It was a questionnaire-based cross-sectional study carried out between August and October 2019 among 100 healthcare workers and 110 mothers from health facilities in Ijebu-Ode Local Government Area of Ogun State, Nigeria. RESULTS Nearly two-thirds (61.0%) of the healthcare workers were community health workers while the others were nurses. Less than a quarter (23.8%) of the healthcare workers had ever attended breastfeeding educational programmes since they started working. About half of the healthcare workers had good knowledge, attitude and practice of BFHI. Nurses had a significantly better practice of BFHI than community health workers. Understaffing was a major limitation to the implementation of BFHI. The mothers had an exclusive breastfeeding rate of 47%. CONCLUSION The knowledge, attitude, and practice of BFHI were suboptimal and the exclusive breastfeeding rate among the mothers was low. There is a need to improve staff strength, training and re-training of staff, as well as regular monitoring and evaluation of healthcare facilities on the implementation of BFHI.

Abstract
Investing in adolescents in Africa holds great promise for the development of the continent. The steps involved in identifying factors linked to interventions that may accelerate the attainment of multiple SDGs for adolescents in Nigeria are described. Data from a survey to investigate the well-being of 1800 adolescents aged 10-19 years in Southwest Nigeria was analysed. A four-step process was employed: 1) Mapping of variables deemed as suitable proxies for SDG targets; 2) Mapping hypothesised protective factors (accelerators) from the study instruments. Consequently, SDG targets related to elimination of hunger, good health, gender equality and peace; and seven accelerators (safe schools, parenting support, good mental health, no survival work, food security, stable childhood, and regular physical activity) were identified; 3) evaluating associations using bivariate analysis and multivariable logistic regression, 4) calculating adjusted probabilities. The mean age of the adolescents was 15.02 ± 2.27 years (48.6% female). Good mental health, not doing survival work, safe schools, stable childhood and parental support were significantly associated with at least two SDG targets. For example, food security was significantly associated with the highest number of SDG outcomes: one SDG target related to child survival (no substance use: x2 = 3.39, p = <0.001); three SDG targets related to educational outcomes (school progression: x2 = 5.68, p = 0.017, ability to concentrate in school: x2 = 26.92, p = <0.001, and school attendance: x2 = 25.89, p = <0.001); and four SDG targets related to child protection (no risky sexual behaviours: x2 = 16.14, p = <0.001, no perpetration of violence: x2 = 15.74, p = <0.001, no community violence: x2 = 39.06, p =<0.001, and no sexual abuse: x2 = 7.66, p = 0.006). Interventions centred around good mental health, not doing survival work, safe schools, small family size, stable childhood and parental support are potential accelerators for the attainment of SDG outcomes by adolescents living in Nigeria.

Abstract
BACKGROUND The adoption of Collaborative Goal Setting (CGS) is limited in most rehabilitation settings in Nigeria despite its recommendations in clinical practice guidelines. OBJECTIVE To explore the perceptions of physiotherapists and patients about CGS at a tertiary healthcare facility in Ibadan, Nigeria. METHODS We conducted focus group discussions among purposively selected physiotherapists (n = 8) and patients (4 stroke survivors, 3 patients with brain injury) to qualitatively explore their perceptions. Audio-taped discussions were transcribed verbatim and thematically analyzed. RESULTS We identified four themes around CGS which were: 1) paternalistic view of goal setting; 2) physiotherapists as goal setters; 3) perceived benefits of collaborative goal setting; and 4) barriers and facilitators to CGS. The physiotherapists articulated goals as expected outcomes from treatment and believed they were better poised and experienced to determine what patients could achieve during each phase of treatment. Patients' view of goal setting agreed with the physio-therapists', as they also opined that goal setting is the responsibility of physiotherapists. Time constraint, inadequate knowledge and the inability of patients to appropriately articulate their goals and expectations from treatment were barriers to CGS. Concerns about who to collaborate with when dealing with patients with impaired cognition and/or disorders of consciousness were raised by the physiotherapists. Participants in both groups indicated that education on how to set patient-oriented goals could facilitate CGS. CONCLUSIONS Though rarely practiced, participants agreed that collaborative goal setting could be beneficial. Both the physiotherapists and patients require education on how to appropriately collaborate in setting goals of rehabilitation.

Abstract
BACKGROUND The z-scoring system shows the mean deviation of cardiac dimensions from age-specific population. The use of the European-based z-score studies has resulted in misdiagnosis and late treatment of Nigerian children with heart diseases leading to increased mortality and morbidity. OBJECTIVES This study aimed to determine the z‑scores for various cardiac structures and functions among healthy children in Southeast Nigeria. MATERIALS AND METHODS This is a cross-sectional observational study where z-scores of the cardiac structure and function of three hundred healthy children were estimated using echocardiography and compared with the standard Detroit values. RESULT There was a significant positive correlation between age and cardiac valve diameter. The aortic valve strongly correlated positively with age with the Pearson correlation coefficient (ρ) of 0.8 and probability value (P-value) of 0.00. None of the ventricular function variables deviated beyond the +2 or -2 z-score. There was a positive correlation between the z-scores of ventricular function parameters and participants' age, although the strength of the correlation varied. Comparing these values with that of Detroit values, there was a significant difference in the deviation of the mean of the mitral valve and left pulmonary artery diameters from the Detroit values between the males and the females. While the mean z-score mitral valve was 0.8 in males, it was 0.6 in females (P = 0.02). CONCLUSION Z-scores of cardiac structures and function are derived from children in this locale. These values were similar to that of Detroit values except for the mitral valve and left pulmonary artery.

Abstract
BACKGROUND Typhoid Fever remains a major cause of morbidity and mortality in low-income settings. The Severe Typhoid in Africa programme was designed to address regional gaps in typhoid burden data and identify populations eligible for interventions using novel typhoid conjugate vaccines. METHODS A hybrid design, hospital-based prospective surveillance with population-based health-care utilisation surveys, was implemented in six countries in sub-Saharan Africa. Patients presenting with fever (≥37·5°C axillary or ≥38·0°C tympanic) or reporting fever for three consecutive days within the previous 7 days were invited to participate. Typhoid fever was ascertained by culture of blood collected upon enrolment. Disease incidence at the population level was estimated using a Bayesian mixture model. FINDINGS 27 866 (33·8%) of 82 491 participants who met inclusion criteria were recruited. Blood cultures were performed for 27 544 (98·8%) of enrolled participants. Clinically significant organisms were detected in 2136 (7·7%) of these cultures, and 346 (16·2%) Salmonella enterica serovar Typhi were isolated. The overall adjusted incidence per 100 000 person-years of observation was highest in Kavuaya and Nkandu 1, Democratic Republic of the Congo (315, 95% credible interval 254-390). Overall, 46 (16·4%) of 280 tested isolates showed ciprofloxacin non-susceptibility. INTERPRETATION High disease incidence (ie, >100 per 100 000 person-years of observation) recorded in four countries, the prevalence of typhoid hospitalisations and complicated disease, and the threat of resistant typhoid strains strengthen the need for rapid dispatch and implementation of effective typhoid conjugate vaccines along with measures designed to improve clean water, sanitation, and hygiene practices.

Abstract
We have investigated the occurrence, distribution, and biomagnification of per- and polyfluoroalkyl substances (PFAS) in two tropical lakes (Asejire and Eleyele) of Southwestern Nigeria, with contrasting urban intensities. Over an 8-month period, we sampled sediment and fish species (Clarias gariepinus: CIG; Oreochromis niloticus: ON; Coptodon guineensis: CG; Sarotherodon melanotheron: SM) across trophic levels, and analyzed various PFAS congeners, in addition to a select group of toxicological responses. While herbivores (SM) and benthic omnivores (CIG) at Asejire exhibited elevated levels of PFBS and PFOS, the pelagic omnivores (ON) showed a dominance of PFOS, PFDA, PFHxDA and EtFOSE in the muscle. At the Eleyele urban lake, PFAS patterns was dominated by PFBS, EtFOSE, PFPeS, PFOcDA and PFOS in the herbivores (SM, CG), EtFOSE, PFOS and PFBS in the pelagic omnivore (ON) and benthic omnivore (ClG). The estimated biomagnification factor (BMF) analysis for both lakes indicated trophic level increase of PFOS, PFUnA and PFDA at the suburban lake, while PFOS and EtFOSE biomagnified at the urban lake. We detected the occurrence of diSAMPAP and 9CL-PF3ONS, novel compounds not commonly reported, in PFAS studies at both lakes. The studied toxicological responses varied across trophic groups in both lakes with probable modulations by environmental conditions, trophic structure, and relative PFAS exposures in the lakes. The present study documents, for the first time in Nigeria, or any other African country, the role of urbanization on contaminant load into the environment and their implications for contaminant dynamics within the ecosystem and for aquatic food safety.

Abstract
Bats are not only ecologically valuable mammals but also reservoirs of zoonotic pathogens. Their vast population, ability to fly, and inhabit diverse ecological niches could play some role in the spread of antibiotic resistance. This study investigated non-aureus staphylococci and Mammaliicoccus colonization in the Hipposideros bats at Obafemi Awolowo University, Ile-Ife, Nigeria. Pharyngeal samples (n = 23) of the insectivorous bats were analyzed, and the presumptive non-aureus staphylococcal and Mammaliicoccus isolates were confirmed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). The isolates were characterized based on antibiotic susceptibility testing and whole-genome sequencing (WGS). Six bacterial genomes were assembled, and three species were identified, including Mammaliicoccus sciuri (n = 4), Staphylococcus gallinarum (n = 1), and Staphylococcus nepalensis (n = 1). All the isolates were resistant to clindamycin, while the M. sciuri and S. gallinarum isolates were also resistant to fusidic acid. WGS analysis revealed that the M. sciuri and S. gallinarum isolates were mecA-positive. In addition, the M. sciuri isolates possessed some virulence (icaA, icaB, icaC, and sspA) genes. Multi-locus sequence typing identified two new M. sciuri sequence types (STs) 233 and ST234. The identification of these new STs in a migratory mammal deserves close monitoring because previously known ST57, ST60, and ST65 sharing ack (8), ftsZ (13), glpK (14), gmk (6), and tpiA (10) alleles with ST233 and ST234 have been linked to mastitis in animals. Moreover, the broad host range of M. sciuri could facilitate the dispersal of antibiotic resistance genes. This study provides evidence of the importance of including migratory animals in monitoring the development and spread of antibiotic resistance.

An empirical analysis of the demand for family planning satisfied by modern methods among married or in-union women in Nigeria: Application of multilevel binomial logistic modelling technique. PLoS One 2024; 19:e0300744. [PMID: 38512904 PMCID: PMC10956820 DOI: 10.1371/journal.pone.0300744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
BACKGROUND Given the health and economic benefits of family planning (FP), Nigeria's very low demand for FP satisfied by modern methods (mDFPS) of less than 50% is therefore a major public health concern, especially considering the global target aimed at achieving an mDFPS of at least 75% by year 2030 for all countries. In view of this, together with recognising the possible contextual nature of health outcomes, this study aimed to empirically analyse the mDFPS among married or in-union women of reproductive age (WRA) in Nigeria. MATERIALS AND METHODS A multilevel binomial logistic model with two levels of analysis was used: individual and community levels. Secondary cross-sectional data were obtained from the 2018 Nigeria Demographic and Health Survey, and analyses were performed using Stata 15.0. The analytical sample size was 9,122 WRA nested in a total of 1,072 communities. RESULTS The mDFPS was approximately 31.0%. The median odds ratio (MOR) estimated from the final multilevel model was 2.245, which was greater than the adjusted odds ratio (aOR) for most of the individual-level variables, suggesting that the unexplained/residual between-community variation in terms of the odds of women having their mDFPS was more relevant than the regression effect of most of the individual-level variables. This was with the exception of the regression effects of the following individual-level variables: women's husbands that had higher education level in comparison to their counterparts who had husbands with no formal education (aOR = 2.539; 95% CI = 1.896 to 3.399; p<0.001); and women from the Yoruba ethnic group in comparison to their counterparts from the Hausa/Fulani/Kanuri ethnic group (aOR = 2.484; 95% CI = 1.654 to 3.731; p value<0.001). However, other individual-level variables with positive statistically significant regression effects on mDFPS were: women who mentioned that money for accessing health care was not a problem; women's empowerment in relation to the visitation of family and relatives; and women being exposed to FP messages through various media sources, all in comparison to their respective counterparts. On the other hand, at the community level, women in communities where a high percentage of them had at least a secondary education had statistically significant greater odds of having mDFPS than women in communities with lower education levels (aOR = 1.584; 95% CI = 1.259 to 1.991; p<0.001). We found similar findings regarding women residing in communities with exposure to FP messages through various media sources. However, using the 80% interval ORs (80% IORs) as a supplemental statistical measure for further understanding the regression effects of community-level variables showed that all of the 80% IORs had a value of '1', signifying considerable uncertainty in the regression effects of all community-level variables due to the substantial residual variation existing between communities. CONCLUSIONS Our study showed that to achieve the dire increase in mDFPS in Nigeria, policy interventions aimed at improving the education level of both females and males, especially beyond the secondary school level, should be implemented. Additionally, all of the various media sources should be extensively utilised, both at the individual and the community level, by the Nigerian government to spread information on the importance of women having their mDFPS.

Abstract
The presence of antimicrobials in water has grown into a major global health concern. This study thus focused on the presence, ecological implications, and potential health risks associated with nine antimicrobials: five antibiotics (ampicillin, chloramphenicol, ciprofloxacin, metronidazole, and tetracycline) and four parabens (methylparaben, ethylparaben, propylparaben, and butylparaben) in surface water and groundwater samples collected from three Southwestern States in Nigeria (Osun, Oyo, and Lagos States). These antimicrobials were widely detected across the three States with ciprofloxacin being the most dominant having maximum average concentrations of 189 μg L-1 and 319 μg L-1 in surface water and groundwater respectively. The range of average concentrations of antibiotics in surface water are 47.3-235 μg L-1 (Osun), 27.9-166 μg L-1 (Oyo) and 52.1-159 μg L-1 (Lagos). For groundwater, it is 35.3-180 μg L-1 (Osun), 26.5-181 μg L-1 (Oyo) and 32.3-319 μg L-1 (Lagos). The average concentrations of all parabens were 32.4-153 μg L-1, 53.4-80.1 μg L-1, and 83.2-132 μg L-1 for surface water and 46.7-55.7 μg L-1, 53-117 μg L-1, and 62.4-118 μg L-1 for groundwater in Osun, Oyo, and Lagos States respectively. Methylparaben was most frequently detected paraben with average concentrations of 153 μg L-1 and 117 μg L-1 in surface water and groundwater respectively. The measured environmental concentrations of these antimicrobials pose a significant ecological risk while those of ciprofloxacin and ampicillin pose a high health risk to all population groups studied. The average concentrations of antibiotics investigated in this study exceeded their threshold values for Predicted No-Effect Concentrations (PNEC) associated with resistance selection, except for tetracycline.

Abstract
INTRODUCTION In Nigeria, breast cancer (BC), a disorder marked by the unchecked growth of breast cells, has been the commonest cancer among women in Nigeria. Breast self-examination (BSE) is one of the suggested methods for screening for the early diagnosis of breast cancer. However, studies have reported inadequate knowledge, negative attitudes and poor practices of BSE among undergraduate female students. The study was designed as an interventional study to examine the effect of educational intervention on knowledge, attitude and practice of breast self-examination among female students in a private university in southern Nigeria. METHODS This pretest posttest design study was carried out on 103 students of Novena University at baseline in 2022, which were chosen through the use of simple random sampling. A validated questionnaire with components on demographics, knowledge, attitude, and BSE practice was used to gather the data. After that, the students participated in three hourly sessions of an educational intervention for two weeks. A month later, the students' data were once again collected, and SPSS 20 software was used to evaluate the results using the mean, paired t test, and logistic regression at the P < 0.05 level of significance. RESULTS The mean age of the respondents was 22.37 ± 1.92 years. Only 53 (51.3%) were aware of BSE. The mean knowledge, attitude and practice of BSE at pretest significantly increased at posttest after the educational intervention (1.58 ± 1.48 vs. 4.31 ± 1.15, 2.37 ± 1.27 vs. 4.80 ± 0.49 and 1.97 ± 0.09 vs. 5.81 ± 3.26, respectively). Furthermore, age and family history of BC were predictors of knowledge (OR = 4.00 95% CI = 0.29-41.99, OR = 141, 95% CI = 0.15-13.18), attitude (OR = 2.39, 95% CI = 0.28-12.32, OR = 1.15, 95% CI = 0.24-8.34) and practice of BSE (OR = 2.66, 95% CI = 0.38-18.41, OR = 1.44, 95% CI = 0.24-8.34) respectively. CONCLUSION The findings showed that using an educational intervention strategy will improve the knowledge, attitude and practice of BSE among undergraduate students.

Abstract
BACKGROUND With the rapid growth of Nigeria's older population, it has become important to establish age-friendly healthcare systems that support care for older people. This study aimed to explore the barriers and facilitators to the delivery of age-friendly health services from the perspectives of primary healthcare managers in Lagos State, Nigeria. METHOD We conducted 13 key informant interviews including medical officers of health, principal officers of the (Primary Health Care) PHC Board and board members at the state level. Using a grounded theory approach, qualitative data analysis was initially done by rapid thematic analysis followed by constant comparative analysis using Dedoose software to create a codebook. Three teams of two coders each blind-coded the interviews, resolved coding discrepancies, and reviewed excerpts by code to extract themes. RESULTS The main barriers to the delivery of age-friendly services included the lack of recognition of older adults as a priority population group; absence of PHC policies targeted to serve older adults specifically; limited training in care of older adults; lack of dedicated funding for care services for older adults and data disaggregated by age to drive decision-making. Key facilitators included an acknowledged mission of the PHCs to provide services for all ages; opportunities for the enhancement of older adult care; availability of a new building template that supports facility design which is more age-friendly; access to basic health care funds; and a positive attitude towards capacity building for existing workforce. CONCLUSION While we identified a number of challenges, these offer opportunities to strengthen and prioritize services for older adults in PHCs and build on existing facilitators. Work is needed to identify and test interventions to overcome these challenges and improve the responsiveness of the PHC system to older adults through the delivery of age-friendly health services in PHCs in Lagos, Nigeria.

Abstract
BACKGROUND Antimicrobial resistance (AMR) remains a significant global health threat particularly impacting low- and middle-income countries (LMICs). These regions often grapple with limited healthcare resources and access to advanced diagnostic tools. Consequently, there is a pressing need for innovative approaches that can enhance AMR surveillance and management. Machine learning (ML) though underutilized in these settings, presents a promising avenue. This study leverages ML models trained on whole-genome sequencing data from England, where such data is more readily available, to predict AMR in E. coli, targeting key antibiotics such as ciprofloxacin, ampicillin, and cefotaxime. A crucial part of our work involved the validation of these models using an independent dataset from Africa, specifically from Uganda, Nigeria, and Tanzania, to ascertain their applicability and effectiveness in LMICs. RESULTS Model performance varied across antibiotics. The Support Vector Machine excelled in predicting ciprofloxacin resistance (87% accuracy, F1 Score: 0.57), Light Gradient Boosting Machine for cefotaxime (92% accuracy, F1 Score: 0.42), and Gradient Boosting for ampicillin (58% accuracy, F1 Score: 0.66). In validation with data from Africa, Logistic Regression showed high accuracy for ampicillin (94%, F1 Score: 0.97), while Random Forest and Light Gradient Boosting Machine were effective for ciprofloxacin (50% accuracy, F1 Score: 0.56) and cefotaxime (45% accuracy, F1 Score:0.54), respectively. Key mutations associated with AMR were identified for these antibiotics. CONCLUSION As the threat of AMR continues to rise, the successful application of these models, particularly on genomic datasets from LMICs, signals a promising avenue for improving AMR prediction to support large AMR surveillance programs. This work thus not only expands our current understanding of the genetic underpinnings of AMR but also provides a robust methodological framework that can guide future research and applications in the fight against AMR.

Abstract
We investigate the factors that influence the selection and productivity of informal service-oriented family enterprises in Nigeria. Using nationally representative micro-data from the Nigerian General Household Survey (2010-2015), we employed random-effect probit and selectivity-adjusted regression models to estimate and analyze the results. The findings reveal that the location of informal Non-Farm Household Enterprises (NFHEs)-whether home-based or non-home-based-significantly impacts the wholesale, retail, personal, and consultancy service sectors operated by informal NFHEs. This impact remains significant even after accounting for variations in individuals, households, or locational characteristics. Furthermore, when considering selectivity in the earnings equation, we found that home-based informal enterprises exhibit lower productivity compared to non-home-based enterprises, a difference that varies across sectors. Overall, factors such as the gender of business owners, educational levels, geopolitical zones, infrastructure, and business characteristics play a crucial role in determining the locational and productivity disparities among service-oriented enterprises in Nigeria. Key recommendations stemming from this study include addressing gender-based segregation and economic disparities, prioritising financial inclusion for small business development, bridging infrastructure gaps, and implementing policies that acknowledge and bolster the informal sector.

Abstract
BACKGROUND Multidrug resistance in Staphylococcus aureus continues to influence treatment complications in clinical settings globally. Multidrug-resistant-S. aureus (MDR-SA) is often genetically driven by resistance markers transferable in pathogenic strains. This study aimed to determine the distribution of resistance markers in clinical isolates of S. aureus in Nsukka, Nigeria. METHODS A total of 154 clinical samples were cultured on mannitol salt agar. Isolates were characterized using conventional cultural techniques and confirmed by PCR detection of S. aureus-specific nuc gene. Antibiotic resistance profiles of the isolates were determined against selected antibiotics using the disk-diffusion method, while screening for antibiotic resistance genes (Mec A, Erm A, Erm B, Erm C, Van A, and Van B) was by PCR. RESULTS A total of 98 isolates were identified as S. aureus by conventional methods. Of these, 70 (71.43%) were confirmed by PCR. Phenotypically, the isolates exhibited high degrees of resistance to oxacillin (95.72%), erythromycin (81.63%), and ertapenem (78.57%) and 75.51% and 47.30% against methicillin and vancomycin, respectively. Multiple antibiotic resistance indexes of the isolates ranged from 0.3 to 1, and the most prevalent pattern of resistance was oxacillin-ertapenem-vancomycin-erythromycin-azithromycin-clarithromycin-ciprofloxacin- cefoxitin-amoxicillin-clavulanic acid. PCR screening confirmed the existence of various antibiotic resistance makers among the strains, with the most common resistance genes found in the isolates being Mec A (32.14%), Van A (21.43%), Van B (10.71%), Erm B (10.71%), and Erm C (17.86%). None possessed the Erm A gene. CONCLUSION The study supports the need for necessary action, including rational drug use, continuous surveillance, and deployment of adequate preventive and curative policies and actions.

Abstract
BACKGROUND Despite the increased risk of cervical cancer (CC) among women living with HIV (WLHIV), CC screening and treatment (CCST) rates remain low in Africa. The integration of CCST services into established HIV programs in Africa can improve CC prevention and control. However, the paucity of evidence on effective implementation strategies (IS) has limited the success of integration in many countries. In this study, we seek to identify effective IS to enhance the integration of CCST services into existing HIV programs in Nigeria. METHODS Our proposed study has formative and experimental activities across the four phases of the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework. Through an implementation mapping conducted with stakeholders in the exploration phase, we identified a core package of IS (Core) and an enhanced package of IS (Core+) mostly selected from the Expert Recommendations for Implementing Change. In the preparation phase, we refined and tailored the Core and Core+ IS with the implementation resource teams for local appropriateness. In the implementation phase, we will conduct a cluster-randomized hybrid type III trial to assess the comparative effectiveness of Core versus Core+. HIV comprehensive treatment sites (k = 12) will be matched by region and randomized to Core or Core+ in the ratio of 1:1 stratified by region. In the sustainment phase, we will assess the sustainment of CCST at each site. The study outcomes will be assessed using RE-AIM: reach (screening rate), adoption (uptake of IS by study sites), IS fidelity (degree to which the IS occurred according to protocol), clinical intervention fidelity (delivery of CC screening, onsite treatment, and referral according to protocol), clinical effectiveness (posttreatment screen negative), and sustainment (continued integrated CCST service delivery). Additionally, we will descriptively explore potential mechanisms, including organizational readiness, implementation climate, CCST self-efficacy, and implementation intentions. DISCUSSION The assessment of IS to increase CCST rates is consistent with the global plan of eliminating CC as a public health threat by 2030. Our study will identify a set of evidence-based IS for low-income settings to integrate evidence-based CCST interventions into routine HIV care in order to improve the health and life expectancy of WLHIV.

Abstract
The COVID-19 pandemic caused a surge in the number of unimmunized and under-immunized children in Africa. The majority of unimmunized (or zero-dose) children live in hard-to-reach rural areas, urban slums, and communities affected by conflict where health facilities are usually unavailable or difficult to access. In these settings, people mostly rely on the informal health sector for essential health services. Therefore, to reduce zero-dose children, it is critical to expand immunization services beyond health facilities to the informal health sector to meet the immunization needs of children in underserved places. In this perspective article, we propose a framework for the expansion of immunization services through the informal health sector as one of the pillars for the big catch-up plan to improve coverage and equity. In African countries like Nigeria, Ethiopia, Tanzania, and the Democratic Republic of Congo, patent medicine vendors serve as an important informal health sector provider group, and thus, they can be engaged to provide immunization services. A hub-and-spoke model can be used to integrate patent medicine vendors into the immunization system. A hub-and-spoke model is a framework for organization design where services that are provided by a central facility (hub) are complimented by secondary sites (spokes) to optimize access to care. Systems thinking approach should guide the design, implementation, and evaluation of this model.

Abstract
Smart lockers are automated delivery machines. They have been used in dispensing ARVs and Tuberculosis medication to chronically ill patients in South Africa, Kenya, and Eswatini. However, there is no evidence of smart lockers in dispensing chronic disease medication in Nigeria. This study aimed to assess the acceptability of smart lockers in dispensing chronic disease medication and to describe the barriers to accessing care among patients with chronic diseases medication in 5 states in Nigeria. We conducted a cross-sectional study among healthcare workers and patients living with chronic diseases in five Nigerian states of Adamawa, Akwa Ibom, Cross River, Benue, and Niger between November and December 2021. A total of 1,133 participants were recruited (728 patients and 405 healthcare workers). The results revealed that most patients and healthcare workers agreed that using smart lockers for drug dispensing will lead to reduced transportation costs, hospital waiting times, the workload of healthcare workers, and decongestion of health facilities. The majority of the patients living with chronic diseases (43%) and healthcare workers (51%) showed high acceptability for the use of smart lockers. The use of smart lockers in dispensing chronic disease medication in Nigeria is feasible, and patients and healthcare workers are willing to accept the smart lockers, provided that a patient-centred implementation strategy is developed.

Abstract
BACKGROUND Community pharmacists play a crucial role in the care of people with depression. This study aimed to evaluate the level of care provided by community pharmacists for clients with depression in Enugu, Nigeria. METHODS A cross-sectional survey was conducted among randomly selected community pharmacists in Enugu, Nigeria. The data obtained were analysed descriptively. KEY FINDINGS Approximately 25% of pharmacists perform depression screening, and 14.4% refer clients to psychiatrists. Pharmacists rarely provide information on antidepressant dosage, side effects, frequency, and duration. CONCLUSION Community pharmacists in Enugu are not providing effective care to depressed patients. Thus, appropriate interventions are recommended.

Abstract
Mosquito-borne diseases (MBDs) are major public health burdens in tropical nations, including Nigeria. This study assessed mosquito larval species composition, abundance, and abiotic factors influencing mosquito breeding in slum communities of Lagos with the goal of informing MBD control measures. Three slum communities-Bariga, Makoko, and Ajegunle-were selected along with the nonslum community of Ikeja, which served as a control site. Larval sampling was done using the standard dipping technique between December 2021 and July 2022 across the dry and wet seasons. Mosquito larvae were raised to adults and identified using morphological keys and molecular assays. A total of 57,753 immature mosquitoes were collected from all study sites, with a significantly (P < 0.05) greater abundance in the dry season than the wet season. The majority (98.1%) of the mosquitoes collected belonged to Culex pipiens s.l., the only species found during the dry season in almost all locations. In the wet season, species identified from all sites combined were Anopheles gambiae ss., Anopheles arabiensis, Aedes aegypti, Aedes albopictus, Cx. pipiens s.l., and Lutzia tigripes, with Ajegunle having the greatest species diversity (H = 0.593). Among physicochemical parameters measured, only water temperature had a significant positive correlation (r = 0.934, P = 0.020) with larval densities in Ajegunle only. Permanent mosquito-breeding habitats had significantly greater larval densities than temporary habitats within the slum communities. These findings could inform the development of integrated vector control strategies that address the different species of mosquitoes in the fight against MBDs in urban slums.

Abstract
BACKGROUND Nigeria has a high proportion of the world's underimmunised children. We estimated the inequities in childhood immunisation coverage associated with socioeconomic, geographic, maternal, child, and healthcare characteristics among children aged 12-23 months in Nigeria using a social determinants of health perspective. METHODS We conducted a systematic review to identify the social determinants of childhood immunisation associated with inequities in vaccination coverage among low- and middle-income countries. Using the 2018 Nigeria Demographic and Health Survey (DHS), we conducted multiple logistic regression to estimate the association between basic childhood vaccination coverage (1-dose BCG, 3-dose DTP-HepB-Hib (diphtheria, tetanus, pertussis, hepatitis B and Haemophilus influenzae type B), 3-dose polio, and 1-dose measles) and socioeconomic, geographic, maternal, child, and healthcare characteristics in Nigeria. RESULTS From the systematic review, we identified the key determinants of immunisation to be household wealth, religion, and ethnicity for socioeconomic characteristics; region and place of residence for geographic characteristics; maternal age at birth, maternal education, and household head status for maternal characteristics; sex of child and birth order for child characteristics; and antenatal care and birth setting for healthcare characteristics. Based of the 2018 Nigeria DHS analysis of 6,059 children aged 12-23 months, we estimated that basic vaccination coverage was 31% (95% CI: 29-33) among children aged 12-23 months, whilst 19% (95% CI:18-21) of them were zero-dose children who had received none of the basic vaccines. After controlling for background characteristics, there was a significant increase in the odds of basic vaccination by household wealth (AOR: 3.21 (2.06, 5.00), p < 0.001) for the wealthiest quintile compared to the poorest quintile, antenatal care of four or more antenatal care visits compared to no antenatal care (AOR: 2.87 (2.21, 3.72), p < 0.001), delivery in a health facility compared to home births (AOR 1.32 (1.08, 1.61), p = 0.006), relatively older maternal age of 35-49 years compared to 15-19 years (AOR: 2.25 (1.46, 3.49), p < 0.001), and maternal education of secondary or higher education compared to no formal education (AOR: 1.79 (1.39, 2.31), p < 0.001). Children of Fulani ethnicity in comparison to children of Igbo ethnicity had lower odds of receiving basic vaccinations (AOR: 0.51 (0.26, 0.97), p = 0.039). CONCLUSIONS Basic vaccination coverage is below target levels for all groups. Children from the poorest households, of Fulani ethnicity, who were born in home settings, and with young mothers with no formal education nor antenatal care, were associated with lower odds of basic vaccination in Nigeria. We recommend a proportionate universalism approach for addressing the immunisation barriers in the National Programme on Immunization of Nigeria.

Abstract
As persons with HIV live longer as the result of antiretroviral therapy, morbidity from HIV-associated noncommunicable diseases (NCDs) is increasing. The Vanderbilt-Nigeria Building Research Capacity in HIV and Noncommunicable Diseases program is a training platform created with the goal of training a cohort of successful Nigerian investigators to become leaders in HIV-associated NCD research. We describe survey findings from two week-long workshops in Kano, Nigeria, where trainees received instruction in implementation science and grant writing. Surveys assessed participants' self-perceived knowledge and confidence in topics taught during these workshops. Thirty-seven participants (all assistant professors) attended the implementation science workshop; 30 attended the grant-writing workshop. Response rates for the implementation science workshop were 89.2% for the preworkshop survey and 91.9% for the postworkshop survey. For the grant-writing workshop, these values were 88.2% and 85.3%, respectively. Improvement in participant knowledge and confidence was observed in every domain measured for both workshops. On average, a 101.4% increase in knowledge and a 118.0% increase in confidence was observed across measured domains among participants in the implementation science workshop. For the grant-writing workshop, there was a 68.8% increase in knowledge and a 70.3% increase in confidence observed. Participants rated the workshops and instructors as effective for both workshops. These workshops improved participants' knowledge and competence in implementation science and grant writing, and provide a model for training programs that aim to provide physician scientists with the skills needed to compete for independent funding, conduct locally relevant research, and disseminate research findings.

Abstract
BACKGROUND Hand hygiene (HH) is a proven low-cost means to curtail the problem of hospital-acquired infection (HAI). However, a low HH compliance rate of 17.1% was found among surgical health workers at Ahmadu Bello University Teaching Hospital (ABUTH) in Zaria, Nigeria. METHODS This was an intervention study conducted utilizing mixed methods to investigate the effectiveness of the World Health Organization (WHO) multimodal strategy to improve the HH compliance rate of doctors at ABUTH Zaria. The study was conducted between June and August 2022 and included delivering a behavioural change HH workshop to doctors followed by data collection in the surgical wards that had received environmental modification through the provision of an alcohol-based hand rub (ABHR), HH posters and nurses for visual and/or verbal reminders. RESULTS The cumulative HH compliance rate was 69% (n=1774) and was significantly different from the baseline HH compliance rate of 17.1% (confidence interval 45.5 to 57.7, p<0.001). Observed HH was highest in the ward with both visual and verbal reminders (78%) and lowest (59%) where neither visual nor verbal reminders were provided (n=444 per ward). All respondents reported motivation to perform HH with the presence of ABHR. CONCLUSIONS The WHO multimodal strategy is good for enhancing HH among health workers in the context of low- and middle-income countries. More research is needed to understand how much of a reduction in HAI is directly associated with efficient HH by health workers.

Abstract
BACKGROUND Nigeria instituted the National Health Insurance Scheme (NHIS) for universal health coverage. This study compared the NHIS and out-of-pocket (OOP) antibiotic prescribing with the World Health Organization (WHO) optimal values. METHODS A total of 2190 prescription forms from the NHIS and OOP were included in this study conducted at Obafemi Awolowo University Teaching Hospitals Complex, Nigeria from January 2021 to December 2022 and analysed using WHO drug prescribing guidelines. RESULTS The average number of drugs per encounter was higher in the NHIS prescribing (χ2=58.956, p=0.00) than in OOP prescribing. The percentage of encounters with an antibiotic prescribed is higher in NHIS prescribing (χ2=46.034, p=0.000) than in OOP prescribing. The percentage of parenteral antibiotic prescribing is higher in OOP prescribing (χ2=25.413, p=0.000) than in NHIS prescribing. The percentage of antibiotic prescribed from the National Essential Medicine List is higher in NHIS prescribing (χ2=8.227, p=0.000) as well as the antibiotics prescribed from the Access category of the WHO Access, Watch and Reserve (AWaRe) Classification of antibiotics (χ2=23.946, p=0.000) when compared with OOP prescribing. CONCLUSIONS Prescribing indicators show better performances with NHIS antibiotic prescribing and are closer to the WHO-recommended optimal values than in OPP prescribing. Hence NHIS prescribing can be an easy target for hospital antibiotic stewardship intervention for optimal antibiotic prescribing.

Abstract
With rapid urbanization, balancing urban ecological infrastructure (UEI) construction and residents' ecological demands (RED) has become an imperative but challenging issue for sustainable development. This study develops an integrated framework to systematically prioritize UEI implementation based on localized RED and government policies. We incorporate the Kano model and quality function deployment (QFD) approach to quantify the complex associations between various resident needs and existing policies. Taking Chengdu City as a case study, resident surveys and policy reviews are conducted to construct the demand-policy linkage matrix and determine the importance of UEI tasks. Results reveal that, (1) flood control capacity is most prioritized by RED, followed by wetland area and less PM2.5, while cultural service demands rank lower; (2) Forest coverage, green space development, wetland construction and park construction emerge as priority UEI implementation tasks that can maximize fulfilling RED. This novel framework enables adaptive customization of UEI planning for different cities through configurable modeling. It provides a valuable decision support tool that enables optimizing or improving the prioritization of UEI implementation tasks based on residents' preferences. The research results have important reference value for the prioritization of UEI implementation tasks.

Abstract
Lateritic soils are prevalent in the tropical regions, and they are used for various construction purposes including landfill liner applications. However, their contaminant attenuation potentials through sorption and the influence of parent rocks on this property are poorly understood. This study investigates lateritic soils from southwestern Nigeria as barrier to leachate migration in engineered landfills and related waste containment facilities. The lateritic soils were investigated through X-ray diffraction (XRD), geochemical analysis and batch equilibrium sorption test to evaluate the competitive sorption of Mn, Cd, Pb, Cu and Cr which are common in landfill leachates. The XRD analysis shows that the kaolinite and dickite are the dominant clay minerals present in the lateritic soils, implying low desiccation cracking and low shrink-swell behaviour. The geochemical analysis indicate that the lateritic soils are silico-alumino-feruginuous with average major oxide composition of SiO2, Al2O3and Fe2O3 of 50.86 wt%, 29.83 wt% and 14.29 wt%), respectively. Additional oxides with lower abundance include TiO2 (1.55 wt%), Na2O (0.01 wt%), MgO (0.36 wt%), CaO (0.15 wt%) and K2O (1.52 wt%). The lateritic soils contain trace amount of heavy metals with average concentrations of Cd (0.039 ppm), Pb (0.548 ppm), Cr (0.189 ppm), Cu (0.964 ppm), Mn (0.145 ppm). Furthermore, the low abundance of sodium oxide in the lateritic soils indicates that the soil particles are not susceptible to dispersion while the presence of considerable amount of iron and manganese oxides signify its good heavy metal retention. The batch equilibrium sorption analysis shows that the lateritic soils derived from granite-gneiss and charnockite exhibit better sorption potential than those derived from schist and quartzite. This high sorption capacity is intricately related to the presence of goethite in the soils. The sorption of these trace metals onto the lateritic soils follows Langmuir type isotherm and these isotherms deviate from the corresponding desorption isotherms to different degrees indicating various extents of hysteresis. The sorption hysteresis indices for these trace metals range from 0.63 to 0.99 and imply that the trace metals may re-leached to the surrounding soils and groundwater. Thus, it is recommended that landfill liners utilizing these lateritic soils are design as a composite containment facility by integrating compacted soil liners, leachate collection systems and monitoring networks to ensure effective environmental protection.

Abstract
BACKGROUND The presacral space is a clinically relevant potential space and contents may give rise to a variety of benign and malignant conditions, hence the need for detailed knowledge of its dimensions. PURPOSE To determine the width of the presacral space and existing variations among adults in south-western Nigeria using a magnetic resonance imaging (MRI) technique. MATERIAL AND METHODS A total of 369 consenting adults were included in the study. Measurements of the presacral space were then made electronically by consensus of two radiologists. Values derived were recorded and subjected to analyses of variance. RESULTS The mean normal widths of the presacral space in men and women were 11.7 mm and 11.1 mm at the S1 level, 11.7 mm and 10.35 mm at the S2 level, and 12.3 mm and 9.7 mm at the S3 level, respectively. Measurements of the presacral space width were significantly larger in the male population. Variations in the dimensions due to age greater than 40 years, male sex, and increasing body mass index (BMI) were also noted. CONCLUSION This study provides baseline dimensions under more physiological conditions and gives more accurate information about the true width of the space in Nigerian adults. Variations due to age, sex, and BMI may also be considered while interpreting abnormal values.

Abstract
This study compared the effect of interactive media-based cognitive behaviour, art, and music therapies in reducing depression in children who survived abduction in Nigeria. A randomized control trial was conducted using three randomly selected secondary schools in Northern Nigeria. The study sample comprised 450 children randomly divided into a control group of (n = 225) and an experimental group of (n = 225). The treatment group was further divided into three groups; cognitive behavior (n = 75), art (n = 75), and music (n = 75) therapy, respectively. According to the findings of this study, cognitive behaviour, art, and music therapies via interactive media are a successful intervention technique for treating the depression of schoolchildren who survived abduction in Nigeria. However, compared to art and music therapy, cognitive behaviour therapy is more effective at treating depression. To lessen the depression of children who survived kidnapped in Nigeria, we recommend adopting cognitive behavioural therapy.

Abstract
Existing knowledge of how maternal autonomy relates to child undernutrition in Nigeria is few and limited to children under 24 months old. Nothing is known about how it affects older children. Therefore, this study investigated whether mothers' household autonomy affects children 24-59 months, as do children under 24 months old. We used data from 2018 Nigerian Demographic and Health Survey, which is a nationally representative survey. Samples include 3502 and 5463 children under 24 months and between 24 and 59 months old, respectively. Three anthropometry indexes were used to determine child undernutrition: weight-for-height, height-for-age, and weight-for-age, which indicate wasting, stunting, and underweight, respectively. Three domains of maternal autonomy: decision-making, financial-control, and mobility, were operationalized using responses from mothers. Results from logistic regression analysis show that in unadjusted models, maternal decision-making autonomy and mobility were associated with undernutrition in both samples. After adding covariates, only associations between maternal decision-making autonomy and underweight in children 24-59 months old retained statistical significance. Findings show that gendered social inequalities are linked to differences in child nutritional outcomes. Future studies could investigate how feeding practices mediate associations between maternal autonomy and childhood undernutrition.

Abstract
Nigeria sits at the crossroads of West and Central Africa; two increasingly critical regions for global health security. To strengthen cross-border collaboration for health security between its neighbors from West and Central Africa, the Federal Ministry of Health, Nigeria through the public health authority at the Points of Entry-Port Health Services, led the design of a multi-lateral framework for cross-border collaboration between Nigeria, the Republic of Benin, the Republic of Chad, the Republic of Cameroon and the Republic of Niger. This framework provides a platform for agreeing on bilateral national and district-level infectious disease surveillance information sharing as well as laying the groundwork for expanded collaboration in incident reporting, joint investigation and response across borders.

Abstract
Universal Health Coverage (UHC) can only be achieved if people receive good quality care from health workers, yet in Nigeria, as in many other low- and middle-income countries (LMICs), many health workers are absent from work. Absenteeism is a well-known phenomenon but is often considered as the self-serving behaviour of individuals, independent from the characteristics of health systems structures and processes and the broader contexts that enable it. We undertook a qualitative inquiry among 40 key informants, comprising health facility heads and workers, community leaders and state-level health policymakers in Nigeria. We employed a phenomenology approach to examine their lived experiences and grouped findings into thematic clusters. Absenteeism by health workers was found to be a response to structural problems at two levels -midstream (facility-level) and upstream (government level) - rather than being a result of moral failure of individuals. The problems at midstream level pointed to an inconsistent and unfair application of rules and regulations in facilities and ineffective management, while the upstream drivers relate mainly to political interference and suboptimal health system leadership. Reducing absenteeism requires two-pronged interventions that tackle defects in the upstream and midstream rather than just focusing on sanctioning deviant staff (downstream).

Abstract
ABSTRACTEnvironmental and health risks posed by radionuclides in quarry pit soils are of great concern in environmental health monitoring. The current investigation was aimed at determining the natural radionuclide activity concentration (in Bq kg-1) of the understudied quarry pit granules used as construction materials. The collection and preparation of pit soil samples from Abeokuta quarry sites were done using standard methods, analysis of radiological parameters was carried out using hyperpure germanium (HPGe) spectrometer. Specific activity concentrations of 226Ra, 232Th, and 40K were measured. The values obtained were greater than the world weighted average of 35, 30, and 400 Bq kg-1 for 226Ra, 232Th, and 40K, respectively. The absorbed dose, the annual effective dose, and the radium equivalent were calculated and demonstrated significant values. The radionuclide content of the samples is relatively high and the use of pit soils as a building material, therefore, raises radiological concerns for dwellers in this area and requires periodic monitoring and undergoing a radiation protection program.

Abstract
Agriculture in sub-Saharan Africa remains highly vulnerable to climate related shocks, since most production relies on rainfall. It is important to accurately measure the resilience of farmers and farming communities to weather variabilities, for both government policy and farmer management responses. This paper develops a Resilience Index Framework, which is further used to assess the resilience of farmers to climate shocks in Nigeria. We conceptualized our Resilience Index (RI) in this study to be a composite function of 60 indicators encompassing four resilience domains namely, Economic & Financial Resilience (ER); Technical-know-how Resilience (TR); Social Resilience (SR); and Physical Resilience (PR). A three-stage standardization approach to construct the resilience index is taken in this study. In the first stage, each indicator is standardized. In the second stage, the resilience domain is computed by averaging the corresponding standardized indicators. In the final stage, the composite RI is computed by estimating the weighted average of all the resilience domains. The study uses the baseline survey data collected between 2021 and 2022 from a total of 5954 farmers in the rainforest, derived and guinea savannah agroecological zones of Nigeria. The result of the study shows that the majority (96.5%) of the farmers are less resilient to climate shocks, with only 0.9% economically & financially resilient, 1.4% socially resilient, 31.4% technically resilient, and 18.5% physically resilient. Finally, some recommend steps to be taken by the government and relevant stakeholders to improve the resilience of farmers through provision of good infrastructural facilities and subsidized improved resistant seed varieties are proposed.

Abstract
Stillbirth commonly affects women in Nigeria, but their experiences of grief following stillbirth is under explored. This study aimed to describe Nigerian women's experiences of grief after stillbirth. Face-to-face, semi-structured interviews were conducted with 20 women in Nigeria who experienced stillbirth. The results from the thematic analysis suggest that mothers had an unmet need to see their stillborn baby, and they experienced communication challenges such as being blindsided/misled about the baby during their interactions with health personnel. The participants experienced emotional and psychological reactions to grief that manifested in the form of emotional pain, sadness, blame and shock, but having a sense of gratitude helped them cope. The findings of this study highlight gaps in bereavement care and suggest the need for basic bereavement training for health personnel.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are known to be representative carcinogenic environmental pollutants with high toxicity. However, information on the potential ecological and environmental risks of PAH contamination in soil remains scarce. Thus, this study was evaluated the potential ecological risks of PAHs in soils of five Korean areas (Gunsan (GS), Gwangju, Yeongnam, Busan, and Gangwon) using organic carbon (OC)-normalized analysis, mean effect range-median quotient (M-ERM-Q), toxic equivalent quantity (TEQ) analysis, and risk quotient (RQ) derived by the species sensitivity distribution model. In this study, atmospheric particulate matter has a significant effect on soil pollution in GS through the presence of hopanes and the similar pattern of PAHs in soil and atmospheric PAHs. From analysis of source identification, combustion sources in soils of GS were important PAH sources. For PAHs in soils of GS, the OC-normalized analysis, M-ERM-Q, and TEQ analysis have 26.78 × 105 ng/g-OC, 0.218, and 49.72, respectively. Therefore, the potential ecological risk assessment results showed that GS had moderate-high ecological risk and moderate-high carcinogenic risk, whereas the other regions had low ecological risk and low-moderate carcinogenic risk. The risk level (M-ERM-Q) of PAH contamination in GS was similar to that in Changchun and Xiangxi Bay in China. The Port Harcourt City in Nigeria for PAH has the highest risk (M-ERM-Q = 4.02 and TEQ = 7923). Especially, compared to China (RQPhe =0.025 and 0.05), and Nigeria (0.059), phenanthrene showed the highest ecological risk in Korea (0.001-0.18). Korea should focus on controlling the release of PAHs originating from the PM in GS.

Abstract
This study uses 26 in-depth interviews conducted with people who use drugs (PWUD) who had sought care for chronic non-cancer pain in public health facilities in Nigeria, to explore how drug consumption stigma constitutes patient legitimacy based on neoliberal ideals. It found drug consumption stigma to be salient and pervasive in PWUD health-care encounters, operating through interpersonal interactions and institutionalised policies and practices to shape access to care. Crucially, stigma emerged through disciplinary opioid prescribing and dispensing practices that defined, categorised and marginalised PWUD based on how their drug consumption disrupted normative values of rationality and responsibility. Accounts additionally revealed disengagement from biomedical care and reliance on alternative pain management approaches (e.g. herbal remedies and illegal drugs), which show how structural positions shape the exercise of choice and agency in socially marginalised populations. In conclusion, the study considers the need to improve the health-care experiences of PWUD as a strategy for enhancing health-care engagement and improving health outcomes. It called for interventions to address the structural factors and interactional dynamics that influence stigma in health-care settings as well as for a review of current guidelines and practices to improve access to opioids for chronic non-cancer pain management.

Abstract
In Nigeria and tropical Africa, the bias towards the protection of natural sites on account of terrestrial biodiversity or their resultant ecosystem services has led to a considerably low number of freshwater conservation studies in the region. To close this gap, six lotic freshwater systems in three different natural sites (Obudu Mountains, Agbokim Waterfalls, and Cross River National Park) along the Cameroon border of Nigeria were evaluated for the biodiversity of macroinvertebrates and some aspects of water quality in December 2021 and March 2022. Among other macroinvertebrate-related indices, the community conservation index (CCI), which considers the presence of threatened, rare, and notable species, was used for the conservation evaluation of the freshwater systems. The Ephemeroptera-Plecoptera-Trichoptera (EPT) species were notably rich at the sites, with over 12 species each at the Afundu Stream, Kwa River, Cataract Stream, and Agbokim River. All of the sites had a very high conservation value, according to the CCI, which was greater than 20. Some Obudu sites (Grotto and Becheve streams), despite having fewer EPT taxa, had higher CCI than the Kwa or Agbokim River. This was due to the presence of the endangered damselflies (Africocypha centripunctata and Allocnemis vicki) at the Obudu sites and a rare mayfly species in Nigeria (Tricorythus tinctus), which was reported at Agbokim and Kwa Rivers. The presence of a notable damselfly genus (Pentaphlebia) at the Afundu stream of the Obudu Mountains also raises some hope that the critically endangered damselfly (Pentaphlebia gamblesi), whose adult was last seen in 1973, could still be alive at the site. Canonical Correspondence Analysis revealed that the proportion of scrapers had a strong association with high BOD and EC in Agbokim River, while the Becheve and Grotto streams which had high vegetal cover was positively associated with shredders. Also, increasing DO in Afundu Stream, Kwa River and Cataract Stream was positively associated with EPT richness. This study revealed that more freshwater ecological studies need to be conducted at isolated natural sites and protected areas in Africa. Findings from such studies have implications for preserving freshwater ecosystems of high conservation value from the various threats that characterize the Anthropocene.

Abstract
BACKGROUND AND OBJECTIVES This study examined the roles of rank and its interaction with armed service characteristics, including combat exposure, frequency of deployments, and length of service on psychological distress among non-commissioned military officers (NCOs). METHODS A cross-sectional sample of 256 NCOs (Meanage = 34.10 ± 7.33) of the Nigerian Army deployed to fight Boko Haram in North-East, Nigeria, participated in the study. Data were collected using self-report instruments and analyzed using multiple linear regression. RESULTS The ranks of corporal and lance corporal/private (LCP) were associated with greater psychological distress than the sergeants. However, corporals had higher psychological distress than sergeants and LCPs. Rank accounted for almost twice the variances in psychological distress more than other service characteristics. LCPs had adverse mental health at increased service length than sergeants and corporals. Also, LCPs were more vulnerable to stress at higher combat experience than the corporals. CONCLUSION Other factors may be inherent in rank effect on psychological distress beyond combat experience, deployments, and service length. Nevertheless, these service characteristics are important in the rank effect on psychological distress. Identifying relevant combat-related structural problems may additionally explain the association of rank with psychological distress beyond combat experience, deployments, and service length among NCOs.

Abstract
PURPOSE The objective was to determine the efficacy of intraoperative vancomycin powder in preventing SSIs in neurological surgeries. METHODS A prospective randomized controlled study of patients who had clean cranial and non-implant spine surgeries at the Irrua Specialist Teaching Hospital, Irrua, Nigeria from February 1, 2021 to January 31, 2022. Patients were randomized into two groups. Group A patients had prophylactic intraoperative vancomycin powder applied to the surgical bed before wound closure while group B patients did not. Patients in both groups were followed up for 30 days post-operatively for evidence of SSI. The occurrence of SSIs was determined using clinical and laboratory parameters. Baseline characteristics, operative details, rates of wound infection, and microbiological data for each case were recorded. Data was analyzed using Statistical Package for Scientific Solution (SPSS) version 23 software. RESULTS Forty-two patients were randomized into 2 groups of 21 patients each. The age range of the patients was 20 to 80 years. The majority of the patients were males (32 out of 42). The mean age of patients in group A was 48.05 ± 17.03 years, while group B had a mean age of 45.95 ± 19.14 years. The mean Body Mass Index of patients in groups A and B were 23.92 ± 5.21 and 23.21 ± 3.99 respectively. Seven out of 21 patients (33.3 %) in the control group ( group B) had superficial SSIs while no patient in the experimental group had SSI, p-value < 0.05. The organisms cultured were Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. CONCLUSION Intraoperative vancomycin powder was effective in reducing the rate of SSIs following neurological surgeries and without adverse drug reactions.

Abstract
OBJECTIVES Equitable distribution of quality healthcare services among different subpopulations in China and Nigeria is inconsistent. This necessitates an examination of potential avenues for improving healthcare provision in both countries. A comparative analysis of both health systems was carried out to provide insights into the progress each nation has made, the obstacles they face, and areas both countries can learn from each other. METHODS We assessed 3 key dimensions of these systems using the Hsiao analytical framework. First, we scrutinized the policy levers of the health systems. Next, we evaluated intermediate outcomes, such as access to healthcare and the quality of care. Lastly, we assessed the extent to which the health systems achieve their ultimate goals, including improving citizen health status and enhancing overall patient satisfaction with the healthcare services. RESULTS China surpasses Nigeria in terms of better birth outcomes, life expectancy, and management of communicable diseases. Both countries offer minimal protection against out-of-pocket spending on medical bills, which consequently exacerbates the poverty rate. CONCLUSIONS China surpasses Nigeria in every health metrics. However, Nigeria's healthcare system offers services to a larger proportion of its populace because of the involvement of the private sector in healthcare delivery. Both countries continue to experience significant challenges, such as limited access to healthcare services in rural areas and overall patient dissatisfaction with the quality of care provided.

Abstract
Introduction: Telemedicine practice experiences during the COVID-19 pandemic have not been well documented in resource-constrained settings, such as Nigeria. We set out to assess knowledge, attitude, and factors associated with telemedicine practice during the COVID-19 lockdown, as well as physician experiences in Kano, Nigeria. Methods: We employed a mixed-methods approach, utilizing structured questionnaires administered to 246 physicians, followed by in-depth interviews with a purposive subsample of 20 individuals. The data were analyzed using logistic regression and the framework approach. Results: Overall, 65.0% of the respondents demonstrated moderate to good knowledge of telemedicine. Before COVID, only 47.6% (n = 117) reported practicing telemedicine, compared with 77.2% (n = 190) during the COVID lockdown (p < 0.05). Factors associated with telemedicine practice included having at least 5 years of work experience, working in pediatrics, undergoing senior residency training, receiving formal telemedicine training, possessing good knowledge of telemedicine, and having a positive attitude toward it. The odds of engaging in telemedicine practice were four times higher (adjusted odds ratio = 4.10, 95% confidence interval: 1.79-9.40) for those who practiced it before the pandemic. Challenges identified included knowledge and skill gaps, slow internet connectivity, unstable electricity, and inadequate equipment. Conclusion: To enhance telemedicine practice in resource-limited settings, it is important to focus on strengthening information and communication infrastructure, providing comprehensive clinician training, implementing careful patient selection processes, and improving practice guidelines.

Abstract
High emissions of aerosols and trace gases during nighttime can cause serious air quality, climate, and health issues, particularly in extremely polluted cities. In this paper, an effort has been made to examine the variations in aerosols and trace gases over a sub-Saharan city of Ilorin (Nigeria) during nighttime. We have used Aerosol Robotic Network data of aerosol optical depth (AOD) at 500 nm, Angstrom exponent (AE) (440/870), and precipitable water (WVC). Both AE and WVC showed a decreasing trend of -0.0012% and -0.0010% per year, respectively. We also analyzed nighttime data of carbon monoxide (CO), methane (CH4 ), and ozone (O3 ) from Atmospheric Infrared Sounder and aerosol subtypes from CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation). AOD, AE, and WVC average values are found to be 0.64 ± 0.33, 0.74 ± 0.24, and 3.40 ± 0.97, respectively. As a result of northeasterly winds carrying Saharan dust during the dry season, the greatest value of AOD (1.29) was observed in February. Desert dust aerosols (37.63%) were the most prevalent type, followed by mixed aerosols (44.15%). Winds at a height of 1500 m above ground level were likely transporting Saharan dust to Ilorin. CALIPSO images revealed that Ilorin's atmosphere contained dust, polluted continental, clean maritime, and polluted dust on high AOD days. The National Oceanic and Atmospheric Administration's vertical sounding profiles showed that the presence of high AOD values was caused by the inversion layer trapping aerosol pollution. Average nighttime concentrations of CO, O3 , and CH4 were measured to be 127 ± 18, 29.7 ± 2.1, and 1822.6 ± 12.7 ppbv, respectively. The wavelet coherence spectra exhibited significant quasi-biannual and quasi-annual oscillations at statistically significant levels.

Abstract
Obstetric fistula is a life transforming event resulting in embodied biographical disruption. Survivors suffer myriad long-term physical and emotional consequences. This paper is an account of a narrative inquiry, conducted with 15 fistula survivors in North-central, Nigeria, who described how their identities had been transformed by their condition. A narrative therapeutic approach, using Frank's 'chaos, restitution and quest' typology, was used to map their recovery narratives. 'Chaos', described by Frank as the opposite of restitution, dominated, with women losing hope of recovery. Women's shift towards 'restitution' began with treatment, but inadequate health-care access often delayed this process. In their quest narratives, women's life and identify changes enabled them to derive meaning from their experience of obstetric fistula within the context of their own lives. The findings highlight socio-structural factors raising the risk of obstetric fistula, which in turn causes biographical disruption and hampers sufferers' treatment and recovery. Rehabilitation should include income-generating skills to bring succour to survivors, particularly those whose incontinence persists after repairs.

Abstract
Human health effects can arise from unregulated manual disassembly of electronic waste (e-waste) and/or hydraulic fracturing fluid spills. There is limited literature on the effects of e-waste and hydraulic fracturing wastewater exposure on the male reproductive system. Thus, this proof-of-concept study begins to address the question of how wastewater from two potentially hazardous environmental processes could affect sperm quality. Therefore, three groups of eight-week-old adult mice were exposed (5 d/wk for 6 wks) via a mealworm (Tenebrio molitor and Zophabas morio) feeding route to either: (1) e-waste leachate (50% dilution) from the Alaba Market (Lagos, Nigeria); (2) West Virginia hydraulic fracturing flowback (HFF) fluid (50% dilution); or, (3) deionized water (control). At 24-hours (hr), 3 weeks (wk), or 9-wk following the 6-wk exposure period, cohorts of mice were necropsied and adverse effects/persistence on the male reproductive system were examined. Ingestion of e-waste leachate or HFF fluid decreased number and concentration of sperm and increased both chromatin damage and numbers of morphological abnormalities in the sperm when compared to control mice. Levels of serum testosterone were reduced post-exposure (3- and 9-wk) in mice exposed to e-waste leachate and HFF when compared to time-matched controls, indicating the long-term persistence of adverse effects, well after the end of exposure. These data suggest that men living around or working in vicinity of either e-waste or hydraulic fracturing could face harmful effects to their reproductive health. From both a human health and economic standpoint, development of prevention and intervention strategies that are culturally relevant and economically sensitive are critically needed to reduce exposure to e-waste and HFF-associated toxic contaminants.

Abstract
Intimate partner violence (IPV) is considered a serious public health concern among couples, regardless of the sexual orientation. However, there is a dearth of data about the determining factors of IPV among couples with mixed-romantic orientations, and not much is known about the role that intra-psychic factors play in the relationship between psychological factors and IPV. Therefore, the study set out to examine the mediating role of emotional suppression in the relationship between psychological factors and IPV among couples with mixed-romantic orientations in Nigeria. The study adopted a correlational research design. A total of 241 respondents (61.4% identified as heterosexual and 38.6% as bisexual) in mixed-romantic orientation marriages, were engaged using respondents-driven sampling. Outcomes revealed that emotional suppression (indirectly) mediated the relationship between depressive symptoms [c'-path analysis; b = .029, t(240) = 108, p = <.01; bootstrap =.0573-1715], anxiety [c'-path analysis; b = .027, t(240) = -0.044, p = <.05; bootstrap = .108-.004], stress [c'-path analysis; b = 0.019, t(240) = 0.057, p = <.001; bootstrap = .0247-.0992] and IPV among couples with mixed-romantic orientations. It was concluded that emotional suppression directly and indirectly mediated the relationship between psychological factors and IPV. Recommendations and limitations are discussed.

Abstract
AIM Antibiotic consumption has increased dramatically in recent years, and this increase is predominantly fuelled by low- and middle-income countries. This is a worrying report, as antimicrobial resistance (AMR) is primarily driven by antibiotic consumption. To combat AMR, the Nigerian Ministry of Health established the Antimicrobial Resistance Technical Working Group (AMR-TWG), which developed and implemented the National Action Plan on Antimicrobial Resistance. This study aims to identify and appraise the current situation in the fight against AMR in Nigeria. METHODS This study contains a qualitative descriptive assessment of the advancements and the present status of efforts to combat AMR in Nigeria following the execution of the 2017-2022 National Action Plan (NAP) for AMR. The data for this study is soured primarily from the official national policy document on AMR and the responses of the Tracking AMR Country Self-assessment Survey (TrACSS). RESULTS The results from this study reveal that there have been significant efforts aimed at addressing AMR in Nigeria. These efforts have been focused on improving public awareness of AMR, improving One Health surveillance of AMR, improving infection prevention and control, improving antimicrobial stewardship practices in the country, and investing in research on AMR. However, significant gaps still exist in each of these focus areas that can potentially undermine the attempts that have been made hitherto. CONCLUSIONS Nigeria's commitment to the fight against AMR, as exemplified by the 2017-2022 National Action Plan, needs to be sustained and reinforced to safeguard public health and promote responsible antimicrobial use.

Abstract
BACKGROUND Perinatal death results in long-lasting intense grief for bereaved mothers with a potential to negatively impact on their short- and long-term outcomes and quality of life if inadequately supported in coping with and managing their experience. AIM This study aimed at exploring the lived experience of women, of care and support following perinatal death in South-Western, Nigeria. METHODS A qualitative methodology using Heideggerian phenomenology was used. Fourteen women who had experienced perinatal death in South-Western Nigeria within the last (5) five years were interviewed, and Van Manen's approach to hermeneutic phenomenology was used in data analysis. FINDINGS Four main themes were identified: "they did not tell me the baby died", "response of health care professionals after the baby died", "moving on from hospital", and "support from family". The physical health status of mothers determined how they were informed of perinatal death. Health care professionals were distant, rude, nonempathetic and did not offer emotional support, in some cases. Mothers were given opportunity to see and hold their babies. There was no routine follow-up support in the community, besides a postnatal check-up appointment offered to all mothers regardless of their birth outcome. Family provided emotional support for mothers on discharge. CONCLUSION This study was the first to explore the lived experience of women of the care and support following perinatal death in South-Western, Nigeria. There is a need for healthcare systems to review bereavement care and support provisions for women who experience perinatal death.

Abstract
The World Health Organization has launched campaigns to boost immunisation rates to 70 percent globally by the middle of 2022. However, despite the global success of about 64% COVID-19 vaccination coverage, there is a big gap in Nigeria. To date, only 13.8% of the population has received the recommended dose. This demonstrates a significant disparity between the vaccinated and the unvaccinated. Amidst the wide gap in vaccination, COVID-19 vaccine wastage still occurs in Nigeria. At the end of 2021, it was estimated that over a million doses of the COVID-19 vaccine had been wasted. It is anticipated that there will be more COVID-19 vaccine wastage in Nigeria, because of the combined factors that threaten vaccination uptake including vaccine accessibility, lack of appropriate storage facilities, poor electricity supply, insecurity challenges, and inadequate health promotion. This results in concomitant financial and opportunity losses. In this paper, we discuss COVID-19 vaccine wastage in Nigeria including causes, and solutions that can be applied to mitigate this wastage.
