Background: Poorly managed hypertension is still a serious global public health issue, despite medication. It is unclear what is causing treated hypertensive patients to have trouble achieving their target blood pressure (BP). Aim: The goal of this study was to determine the predictors of BP control amongst hypertensive patients attending a teaching hospital in North-eastern Nigeria. Materials and Methods: A cross-sectional study was conducted on 277 hypertensive patients from a tertiary healthcare institution. Data were analysed using version 20 of the Statistical Package for the Social Sciences (SPSS). Frequency and percentages were used to summarise data while Chi-square test was used to test for associations. To identify the factors linked to BP control, logistic regression was employed. At P < 0.05, predictors of BP control were found using adjusted odds ratios (AORs) with a 95% confidence interval (CI). Results: The respondents' average age was 53.1 ± 14.6 years, of which 67.5% were female. The level of optimal BP control was 40.8%. Factors associated with reduced BP control include not currently married (AOR = 0.29 [95% CI: 0.16–0.53], P ≤ 0.0001), imperfect adherence (AOR = 0.37 [95% CI: 0.22–0.64], P ≤ 0.0001), taking more than two drugs (AOR = 0.3 [95% CI: 0.14–0.64], P = 0.001) and body mass index (BMI) ≥25 kg/m² (AOR = 0.40 [95% CI: 0.22–0.72], P = 0.002). Conclusion: The optimal BP control is alarmingly low in this setting. Marital status, medication adherence, increased pill burden and BMI ≥25 kg/m² negatively affect the attainment of BP control.

Introduction: Histoplasmosis commonly occurs in the advanced HIV disease population and also in immunocompetent individuals. Previous reviews and recent studies highlight several cases of histoplasmosis reported in Nigeria. We aimed to describe the current epidemiology of histoplasmosis in Nigeria and the need for active surveillance in the at-risk populations. Methods: Literature searches for all publications on histoplasmosis in Nigeria were performed using online databases including Google scholar, PubMed and African Journal online. The following search terms: 'histoplasmosis' and 'Nigeria', AND/OR 'Histoplasma and Nigeria' were used. No limitations on the date or other search criteria were applied, to avoid the exclusion of articles on histoplasmosis in Nigeria. All publications on histoplasmosis outside Nigeria were excluded. Results: Our review identified a total of 231 cases of histoplasmosis reported from Nigeria: 128 were from individual case reports and case series while 103 were cases from two observational studies. Of the 231 cases, 97 (42.0%) were from South West Nigeria, 66 (28.6%) were from South-South Nigeria, 24 (10.4%) were from North West, 22 (9.5%) from North Central Nigeria, 17 (7.4%) from South East Nigeria and 5 (2.2%) from the North East. Based on Nigeria's current population size of 216,953,585 the burden of histoplasmosis per 100,000 inhabitants was estimated to be 0.1%. The sheer number of cases detected in recent observational studies compared with individual case reports and series reported over a longer duration of 6 decades suggests gross under-reporting of histoplasmosis in Nigeria. Conclusion: Histoplasmosis is not an uncommon clinical entity in Nigeria. Histoplasmosis case finding should be improved by training and retraining healthcare professionals and providing much-needed diagnostic capacity and infrastructure across health facilities in Nigeria.

Introduction: In Nigeria, immunisation with coronavirus disease 2019 (COVID-19) vaccines commenced in March 2021. COVISHIELD from AstraZeneca (AZ), a viral vector vaccine, was the brand administered in the first phase of vaccinations for pre-determined eligible adults 18 years and above. As more brands of COVID-19 vaccines have been introduced in Nigeria, identifying effective and safe vaccine brands is essential to pharmacovigilance and public health. The current study assessed the safety of the AZ-AZD1222 (ChAdOx1) COVID-19 vaccine in adults during the first phase of the vaccination exercise in Nigeria. Methodology: We conducted a descriptive analysis of safety data from selected vaccination sites across six states in Nigeria between June 2021 and September 2021. Respondents were monitored over 3 months for local and systemic reactions, as well as hospitalisation and mortality. Measures obtained from respondents include age, sex, pre-existing comorbidity, local and systemic reactions to vaccines, timing onset of reactions, hospitalisation and mortality. Bivariate and multivariable regression models were used to assess factors associated with vaccine reactogenicity. Results: A total of 1284 individuals were enrolled in the cohort study from the six selected states (Anambra, Borno, Edo, Katsina, Lagos and Plateau) representing the geopolitical zones of Nigeria. A total of 675 individuals or 52.6% of enrolees reported non-serious adverse effects, and only one individual or 0.08% reported a serious adverse event following immunisation in the first 7 days after vaccination. None of the enrolled participants reported adverse events requiring hospitalisation. The most common self-reported symptoms amongst vaccine recipients were tenderness at the injection site 20.9% and fever 20.3%. A majority of symptoms (55.5%) occurred on or before the 3^rd day after vaccination. Multivariable logistic regression model showed that age 60 years or above (vs. 18–24 years) was significantly associated with a lower likelihood of a vaccine-related symptomatic reaction (adjusted odds ratio: 0.35; 95% confidence interval: 0.20–0.61). There was no reported mortality amongst all the enrolled and followed-up vaccine recipients. Conclusion: Our findings suggest that the safety profile of the AZ vaccine is acceptable, and the observed symptoms were mild and mostly within the first 3 days following vaccination. Vaccine recipients will benefit from counselling about potential transient reactions, and improving public awareness can potentially encourage the uptake of vaccines and reduce the spread of the COVID-19 pandemic.

Context: Adolescence is a crucial phase in preventing and controlling anaemia. One of the efforts made by the Indonesian government to overcome adolescent girl's anaemia is the iron and folic acid (IFA) supplementation programme. This programme is one of the most effective interventions that various countries have used to overcome anaemia. The key to the success of the supplementation of IFA is the compliance of adolescent girls. Aims: This study investigates the compliance and its contributing factors of IFA supplementation and the role of social support and interpersonal trust as a source of information and reminder amongst adolescent girls in Sidoarjo, Indonesia. Methods: This research was a qualitative study using the in-depth interview to collect data. Thirteen adolescent girls from three high schools in Sidoarjo, Indonesia, were recruited using a snowball sampling technique. Results: Most of the girls did not comply with IFA supplementation. Contributing factors were the influence of peers, influence of teachers, parental influence, risk and benefit of taking IFA tablet and also failure to remember to take IFA tablet. The social environment that provided information and reminder came from teacher, parent, peer and also health worker. Interpersonal trust was needed to have positive perceived social support. Conclusions: Compliance with the consumption of IFA supplements requires the cooperation of various parties (teachers, parents, peers and health workers) and also interpersonal trust between adolescent girls to their social environment so the programme could be run optimally.

Background: Adverse pregnancy outcomes occur more commonly in developing countries and are still prevalent in our sub-region. Microalbuminuria is a marker of endothelial dysfunction and has been proposed as an aetiological factor in the development of some adverse pregnancy outcomes such as pre-eclampsia, intrauterine growth restriction (IUGR) and pre-term labour. Aim: The aim is to determine the prevalence of microalbuminuria and its association with adverse pregnancy outcomes. Methods: This was a prospective cross-sectional study with follow-up amongst women in early pregnancy presenting at Usmanu Danfodiyo University Teaching Hospital, Sokoto. Three hundred and thirty women with singleton pregnancy at gestational age <20 weeks, blood pressure <140/90 mmHg, normal fasting blood sugar and normal renal function were recruited. Those with a history of hypertension, diabetes mellitus, chronic kidney disease, sickle cell anaemia were excluded, multiple pregnancies, urinary tract infection or positive dipstick proteinuria at first contact were excluded. They were recruited consecutively and a structured interviewer-administered questionnaire was completed. Single-spot urine analysis for albumin was performed. The women were followed up to the time of delivery and the puerperium and any adverse outcome were documented. Results: The prevalence of microalbuminuria was 58.4%. The maternal and foetal adverse outcomes such as hypertensive disorders of pregnancy, pre-mature rupture of membrane, IUGR, preterm birth and stillbirth occurred more amongst the women with microalbuminuria. However, there was no statistically significant association between microalbuminuria and having these adverse outcomes (P > 0.05). Conclusion: There was a high prevalence of microalbuminuria amongst healthy pregnant women and pregnancy complications occurred more frequently in women with microalbuminuria than in those without. However, this association was not sufficient to predict adverse outcomes in pregnancy.

Carbapenem antibiotics are considered one of the most effective and the last-resort antibiotics for the treatment of infections caused by multidrug-resistant Gram-negative bacteria. However, with the advent of carbapenem resistance, it becomes obvious that quality health-care delivery will be hampered if adequate measure is not put in place. This review assessed the prevalence of carbapenem-resistant Gram-negative bacteria (CR-GNB) and also provided an up-to-date position on carbapenem resistance (CR) in Nigeria. Three electronic databases (Google Scholar, PubMed and African Journal online) were searched for relevant literatures, and 38 articles published between January 2013 and June 2022 that met the criteria for inclusion were recruited into the study. The mean prevalence of CR in Nigeria stands at 21.3%, with the southern and northern regions documenting a mean prevalence of 22.0% and 20.9%, respectively. Most of the reviewed articles were from clinical settings (81.6%), with urine samples (38.7%) constituting the most prevalent clinical sample in which CR-GNB were detected. The preponderance of phenotypic methods (55.3%) over molecular method (44.7%), particularly the use of disk diffusion test breakpoint and Modified Hodge test was documented. The most prevalent carbapenem-resistant bacteria were Escherichia coli (50.0%) and Klebsiella pneumoniae (26.3%). The blaNDM and blaVIM were the major reported carbapenemase-encoded genes, particularly among E. coli, K. pneumoniae and Pseudomonas species. This systematic review revealed a mean prevalence of CR-GNB in Nigeria that required urgent attention. Furthermore, the detection of clinically and epidemiologically important carbapenemase coding genes is of public health importance.

Background: It is predicted that the population of sub-Saharan Africa will be thrice its size by the end of the 21^st century. Our study compared patterns, incentives and disincentives for the uptake of contraceptives in rural and urban communities of Lagos, Nigeria. Materials and Methods: This is a population-based cross-sectional study on 1445 women of reproductive ages 15–49 years using a cluster sampling technique and a pre-tested, interviewer-administered electronic questionnaire in 2020. Data were analysed using the Statistical Package for the Social Sciences (SPSS) software version 26.0 and ethical approval was obtained for the study. Results: About 32.4% of the respondents were rural dwellers and 67.6% were urban residents. The overall mean age was 31.7 ± 7.8 years. In terms of pattern, slightly over half (53.3%) of all respondents had ever used family planning (FP), including modern contraceptives and slightly less than a third (30.8%) currently use FP methods in both rural and urban communities, respectively. Predominant disincentives for non-use of FP include a desire to retain fertility, lack of further need, unbearable side effects and lack of spousal support. The odds of being an urban dweller currently using a method of contraceptive method is 4.169 times higher for earners above ₦60,000, which is twice the minimum wage compared to those without income (adjusted odd's ratio: 4.169, 95% confidence interval: 1.395–12.462). Conclusion: Sustained effort is required to improve contraceptive uptake, FP service delivery and demand satisfaction for modern contraceptives to enable the achievement of demographic dividends and gains.

Introduction: The scalp hairs on an average African is dry with low tensile strength and a tendency to break easily. This is mostly due to poor penetration of the natural oils on the scalp and the very curly hair texture. Various techniques developed to manage African hair are associated with certain hair and scalp disorders and are sources of distress. Objectives: This was a cross-sectional survey to compare natural African hair and chemically processed (relaxed) hair to determine the effect of hair care and grooming practices on common scalp disorders and the psychological effect in Nigerian women. Subjects and Methods: Questionnaires were administered to women at the market, churches and outreaches with many women in attendance to document the hair grooming practices, common scalp symptoms and psychological effects experienced. They were also examined for the presence of seborrhoeic dermatitis and traction alopecia. Results: The study involved 452 women (62.17%) with relaxed hair and 275 women (37.83%) with natural (untreated) hair. Women with relaxed hair experienced significantly more flaking of the scalp (P = 0.046, x² = 6.16), hair breakage (P = 0.023, x² = 11.35) and hair loss (P = 0.020, x² = 7.87) than those with natural hair. The most common psychological effects of hair scalp disorders in all participants were feeling of uneasiness 142 (19.5%), frustration 49 (6.7%), poor body image 40 (5.5%) and anger 38 (5.2%). Significantly more women with relaxed hair experienced moderate hair loss from traction than women with natural hair (P = 0.014, x² = 8.52). Conclusion: Nigerian women experienced clinical and psychological distress consequent to their hair grooming practices. Individuals with relaxed hair had more physical symptoms, hair loss and psychological disturbances than those with natural hair.

Context: Currently, little is known about the timely application of clinical screening tools and blood sampling for decision-making in the management of patients with suspected sepsis in the accident and emergency units of hospitals in Nigeria. Aim: The aim of the study was to ascertain the association between the time taken for the conduct of serum lactate and blood culture investigations following a clinical suspicion of sepsis, and the mortality of patients admitted to a Nigerian tertiary hospital. Methods: Over a 6-month period (November 2021 to April 2022), 119 patients hospitalised for sepsis or septic shock at the Lagos University Teaching Hospital were followed until discharge or death. The proportion of patients whose serum lactate, serum procalcitonin and blood culture samples was taken was also determined. Predictors of mortality were determined using bivariate analysis and logistic regression. Kaplan–Meier plots were used to predict survival using sepsis diagnostic criteria. Results: Eighty (67%) of 119 sepsis patients met systemic inflammatory response syndrome or quick sequential (sepsis-related) organ failure assessment criteria. Only 3 (2.5%) patients had blood cultures and serum procalcitonin and 0 (0%) had serum lactate tests. Forty-one (34.5%) patients died, but clinical and laboratory procedures for sepsis management were not linked to death. A shorter hospital stay increased the death risk (χ² = 14.83, P = 0.002). Conclusion: This study revealed low compliance with sepsis care guidelines and no impact of timely clinical and laboratory procedures on sepsis mortalities. Further study is needed to explore patient care models that can improve the objective assessment and treatment of sepsis patients in emergency departments of busy tertiary hospitals.

Background: Abortion is one of the leading causes of morbidity and mortality amongst Nigerian women in a country with restrictive abortion laws. Despite being illegal, abortions are still performed, and about 50% of abortions are performed by untrained persons in unhygienic conditions. This study assessed the determinants of attitude of undergraduates to legalisation of safe abortion in Nigeria. Methods: It is a descriptive cross-sectional study. We used a three-stage sampling technique to select 423 undergraduates using a pre-tested questionnaire. The predictors of attitude towards abortion and its legalisation were identified during multivariate analysis. Results: Good knowledge of abortion and its sequelae was found in about two-thirds (62.2%) of the participants, while over half (56.3%) had a negative perspective to abortion legalisation in Nigeria. Older participants were more likely to have positive perspectives to legalisation of abortion compared to their younger counterparts (odds ratio [OR] = 4.72, confidence interval [CI]: 2.61–8.55). Furthermore, respondents from upper social class and those with good knowledge were more likely to have positive perspectives to legalisation of abortion compared to their counterparts (OR = 5.63, CI: 3.12–10.16 and OR = 4.50, CI: 2.89–7.01). Conclusion: The study showed that respondents' knowledge of abortion was relatively low amongst the study population, and more than half of the respondents did not want abortion to be legalised. Increasing awareness on the importance of abortion and its complications in Nigeria will curb the menace of death due to abortion now and in the future.

We report a rare case of a 32-year-old Indian male who presented to the retina outpatient department with a history of sudden worsening of vision in the left eye. There was a background history of poor vision and deficient night vision since childhood. At the first presentation, the best corrected visual acuity was 6/36 and 6/60 in the right and left eye, respectively. Ocular examination revealed waxy pale disc, bone spicule pigmentation, attenuated vessels and epiretinal membrane in the right eye in keeping with retinitis pigmentosa. An astrocytic harmatoma was also present in the right eye. Vitreous haemorrhage in the left eye precluded a view of the fundus. He subsequently had a left pars plana vitrectomy, and intravitreal bevacizumab on account of non-resolving vitreous haemorrhage and a vasoproliferative tumour and astrocytic hamartoma were noticed intraoperatively. He had a good immediate post-operative outcome post-left vitrectomy but subsequently developed left neovascular glaucoma 2 years after. Neovascular glaucoma may be a sequela of vasoproliferative tumour; hence, regular follow-up and monitoring are essential in these patients.

Introduction: Periodic evaluations are an indispensable part of any training programme. This study assessed ophthalmology residency training in Nigeria from the perspective of ophthalmology trainers. Materials and Methods: This was a nationwide web-based survey of ophthalmology trainers at the 30 institutions accredited by the National Postgraduate Medical College of Nigeria from April 2021 to June 2021. Trainers were invited to complete a Google form via E-mail and WhatsApp. Data were collected on the characteristics of trainers and the training programme. Results: One hundred and fifty-eight (71.2%) out of 222 trainers responded to the survey comprising 67 (42.4%) males and 91 (57.6%) females, amongst whom were 97 (61.4%) subspecialists. The mean age (±standard deviation) was 51.47 ± 8.61 years (range, 38–75 years). Most respondents rated human resources (trainers and support staff) as 'much more' than adequate (n = 30, 19%), the volume of surgery as 'less or much less' than adequate (n = 82, 51.9%), the conduct of examinations as 'good' or better than good (n = 120, 75.9%) and impact of emigration of ophthalmologists on training as 'very negative' (n = 36, 22.8%). Overall, 94 (59.4%) respondents rated the quality of training as 'good' or better than good. Respondents recommended improving funding and training resources, revising the current conduct of examinations, increasing the use of appropriate technology and improving remunerations and national security. Conclusions: The majority of ophthalmology trainers rated ophthalmology residency training in Nigeria as 'good' but rated 'volume of surgery' as inadequate for training. Recommendations were made to improve the quality of training, revise examination practices and reduce the negative impact of emigration.
