Assessing post-abortion care using the WHO quality of care framework for maternal and newborn health: a cross-sectional study in two African hospitals in humanitarian settings.

BACKGROUND: Abortion-related complications remain a main cause of maternal mortality. There is little evidence on the availability and quality of post-abortion care (PAC) in humanitarian settings. We assessed the quality of PAC in two hospitals supported by an international organization in Jigawa State (Nigeria) and Bangui (Central African Republic, CAR). METHODS: We mapped indicators corresponding to the eleven domains of the WHO Maternal and Newborn Health quality-of-care framework to assess inputs, processes (provision and experience of care), and outcomes of PAC. We measured these indicators in four components of a cross-sectional multi-methods study: 1) an assessment of the hospitals' PAC signal functions, 2) a survey of the knowledge, attitudes, practices, and behavior of 140 Nigerian and 84 CAR clinicians providing PAC, 3) a prospective review of the medical records of 520 and 548 women presenting for abortion complications and, 4) a survey of 360 and 362 of these women who were hospitalized in the Nigerian and CAR hospitals, respectively. RESULTS: Among the total 27 PAC signal functions assessed, 25 were available in the Nigerian hospital and 26 in the CAR hospital. In both hospitals, less than 2.5% were treated with dilatation and sharp curettage. Over 80% of women received blood transfusion or curative antibiotics when indicated. However, antibiotics were given to about 30% of patients with no documented indication. Among discharged women in CAR, 99% received contraceptive counseling but only 39% did in Nigeria. Over 80% of women in Nigeria reported positive experiences of respect and preservation of dignity. Conversely, in CAR, 37% reported that their privacy was always respected during examination and 62% reported short or very short waiting time before seeing a health provider. In terms of communication, only 15% felt able to ask questions during treatment in both hospitals. The risk of abortion-near-miss happening ≥ 24h after presentation was 0.2% in Nigeria and 1.1% in CAR. Only 65% of women in the Nigerian hospital and 34% in the CAR hospital reported that the staff provided them best care all the time. CONCLUSION: Our comprehensive assessment identified that these two hospitals in humanitarian settings provided lifesaving PAC. However, hospitals need to strengthen the patient-centered approach engaging patients in their own care and ensuring privacy, short waiting times and quality provider-patient communication. Health professionals would benefit from instituting antibiotic stewardships to prevent antibiotic-resistance.

In humanitarian contexts, abortion complications are a leading cause of maternal mortality. Providing quality post-abortion care (PAC) is therefore an important part of needed services. We assessed the quality of PAC in two hospitals supported by an international organization in Jigawa State (Nigeria) and Bangui (Central African Republic). We measured quality indicators in four components: 1) an assessment of the equipment and human resources available in hospitals, 2) a survey of the knowledge, attitudes, practices, and behavior of clinicians providing PAC, 3) an assessment of the medical care provided by clinicians to women presenting with abortion complications and, 4) a survey of a subgroup of these women who were hospitalized. Both hospitals had almost all the equipment and human resources necessary to provide post-abortion care. Less than 2.5% of women received a non-recommended method to evacuate their uterus in both hospitals. More than 80% of women received a blood transfusion or antibiotics when they needed them. However, 30% of women received antibiotics without written justification and only 15% of women reported being able to ask questions about their treatment. Overall, only 65% of Nigerian women and 34% of Central African women said that the staff provided them with the best care all the time. The fact that less than 2% of women experienced a very severe complication 24 hours or more after their arrival at the two hospitals suggests that the care provided was lifesaving. But they urgently need to adopt a better patient-centered approach as well as to improve the rational management of antibiotics.

Scaling training facilities for patent and proprietary medicine vendors in Nigeria: insights and lessons learned for policy implication and future partnerships.

Patent and proprietary medicine vendors in Nigeria play a very integral role in providing primary health care services and are an important source of care for the poor. They are located close to communities and are often the first source of care for hygiene and family planning (FP) products and treatment of child illnesses. Since 2017, Pharmacy Council of Nigeria (PCN) has partnered with Society for Family Health through the IntegratE project to address the poor quality of services by patent and proprietary medicine vendors (PPMVs) and reposition them for better service delivery through piloting the three-tier accreditation system. The partnership has engendered innovation for human resource for health, and considering the peculiarity of their situation, new emerging methods and arrangements to deliver the training to PPMVs in diverse geographical locations within their catchment areas are developed. In this study, we aimed to discuss the role of patent and proprietary medicine vendors in the provision of quality health delivery and provide key lessons and recommendations which have been learned from the pilot scaling of training facilities for PPMVs in Nigeria through the IntegratE project. From the lessons learnt, we propose that, for a successful scale-up of implementation of the three-tier accreditation of PPMVs, PCN will have to establish a budget line for accreditation. In addition, the government should also consider supporting this training through the Basic Healthcare Provision Fund as a way of strengthening human resources at the primary healthcare level. Other alternative sources of funding include licensing and registration fees and other dues generated internally by PCN.

Qualitative and quantitative water investigation of Erin-Ijesha (Olumirin) Waterfall, Erin-Ijesha, Nigeria.

This study focused on the assessment of water quality in Erin-Ijesha (Olumirin) Waterfall, a prominent natural attraction in southwestern Nigeria. The physiochemical parameters, heavy metal concentrations, and bacteriological characteristics were examined in the upstream, midstream, and downstream sections, to ensure the resource quality and safety from harm. The results revealed notable variations in water quality. The pH, Total Dissolved Solids, Electrical Conductivity, and Temperature were highest in the midstream while Total Hardness, Alkalinity, salinity, Chloride, sulphate, Phosphate, Nitrate, Calcium, and Magnesium were highest in the downstream section. The physicochemical parameters were within the acceptable limits of World Health Organization (WHO), United States Environmental Protection Agency (USEPA), and the Standard Organization of Nigeria (SON) standards, except the pH, temperature, and Total Hardness were higher than the acceptable limits of 6.5-8.5, <25 °C or >50 °C and 50 mg/L in all the sections. Iron was above the WHO, USEPA, and SON permissible limits of 3.0 mg/L in all the sections of the river while there was no indication of copper, lead, and cadmium. Bacterial contamination, particularly the presence of E. coli, exceeded recommended safety thresholds. The Total Bacterial Count (TBC) exceeded safety limits by 0.1 million cfu/mL in the downstream. The mean of the parameters was higher in some instances, and sometimes lower than the values in the various sections of the river. A significant relationship existed between most physical, chemical, and bacteriological parameters at p < 0.01. The appraisal of water quality in Olumirin Waterfalls emphasizes the need for proactive measures to ensure water safety, preserve ecosystems, and promote responsible water resource management.

Comparative analysis of virulence gene profiles of Escherichia coli from human and non-human sources in Rivers State, Nigeria.

Traditionally, the presence of virulence features has been thought to be a key factor in differentiating pathogenic from commensal strains. An understanding of the virulence potential of Escherichia coli isolates from various sources is essential to shed light on potential contamination/transmission rates between the various sources. This study was therefore aimed at exploring the occurrence of specific virulence genes and gene profiles associated with E. coli from human and non-human sources in Rivers State, Nigeria. Two hundred samples from human (urine and faeces) and non-human (soil and poultry droppings) sources (50 each) were analysed using standard microbiological procedures. DNA was extracted from isolates presumptively identified as E. coli using the Presto Mini gDNA Bacteria-Kit Quick protocol following the manufacturer's instructions. Isolate identities were confirmed using E. coli-specific 16S rRNA primers, and confirmed isolates were screened for the presence of six virulence genes [afimbriae binding adhesin (afa), type 1 fimbriae (fimH) and P-fimbrial usher protein (papC)], iron acquisition systems: aerobactin (aer), cytotoxic necrotizing factor I (cnf1) and alpha-hemolysin (hly). Results showed that all isolates harboured at least one of the tested virulence genes, with fimH (97%) as the most prevalent virulence gene and papC the least commonly occurring (35%). A higher occurrence of virulence genes was noted in non-human isolates, though hly and cnf were not detected at all in any of the isolates studied (0%). Ten different profiles were observed with the afaCc-aer-fimH profile the most commonly occurring virulence gene profile being in general (33.3%). For non-human isolates, however, aer-afaCc-fimH-papC was the most commonly occurring profile (42.9%). This study shows that the test E. coli from human and non-human sources do not carry distinct virulence gene profiles. Studies on a larger subset of isolates would however be necessary to determine if the virulence genes tested in this study really cannot be used to tell whether an isolate is from a human source or not in the South-South of Nigeria.

Are self-reported fertility preferences biased? Evidence from indirect elicitation methods.

Desired fertility measures are routinely collected and used by researchers and policy makers, but their self-reported nature raises the possibility of reporting bias. In this paper, we test for the presence of such bias by comparing responses to direct survey questions with indirect questions offering a varying, randomized, degree of confidentiality to respondents in a socioeconomically diverse sample of Nigerian women ([Formula: see text]). We find that women report higher fertility preferences when asked indirectly, but only when their responses afford them complete confidentiality, not when their responses are simply blind to the enumerator. Our results suggest that there may be fewer unintended pregnancies than currently thought and that the effectiveness of family planning policy targeting may be weakened by the bias we uncover. We conclude with suggestions for future work on how to mitigate reporting bias.

Detection and management of localized prostate cancer in Nigeria: barriers and facilitators according to patients, caregivers and healthcare providers.

BACKGROUND: Prostate cancer mortality rates are high in Nigeria. While prostate cancer is highly curable with early detection and effective multidisciplinary management, the quality of care is suboptimal in this setting. Sustainable delivery of high-quality care for patients with localized prostate cancer is needed to save more lives. To inform future interventions to improve care, this study aimed to identify barriers and facilitators that influence prostate cancer detection and management in Nigeria. METHODS: Six focus group discussions (FGDs), stratified by stakeholders were conducted with a purposive sample of prostate cancer patients (n = 19), caregivers (n = 15), and healthcare providers (n = 18), in two academic tertiary hospitals in northern and southern Nigeria. A discussion guide organized based on the socio-ecological model was used. FGDs were recorded, transcribed, and analysed using the framework technique. RESULTS: Barriers and facilitators were identified at the individual, interpersonal, and organizational levels. Barriers to detection included limited knowledge and misperceptions among patients, caregivers, and community-based non-specialist healthcare providers, and limitations of centralized opportunistic screening; while facilitators included the potential for religious institutions to encourage positive health-seeking behaviour. Barriers to management included non-uniformity in clinical guideline usage, treatment abandonment amidst concerns about treatment and survival, absence of patient interaction platforms and follow-up support systems, difficulty in navigating service areas, low health insurance coverage and limited financial resource of patients. Facilitators of management included the availability of resource stratified guidelines for prostate cancer management and the availability of patient peers, caregivers, nurses, and medical social workers to provide correct medical information and support patient-centred services. Participants also provided suggestions that could help improve prostate cancer detection and management in Nigeria. CONCLUSION: This study identified multiple determinants affecting the detection and management of localized prostate cancer. These findings will inform the refinement of implementation strategies to improve the quality of prostate cancer care in Nigeria.

Mpox Epidemiology and Risk Factors, Nigeria, 2022.

To investigate epidemiology of and risk factors for laboratory-confirmed mpox during the 2022 outbreak in Nigeria, we enrolled 265 persons with suspected mpox. A total of 163 (61.5%) were confirmed to have mpox; 137 (84.0%) were adults, 112 (68.7%) male, 143 (87.7%) urban/semi-urban dwellers, 12 (7.4%) self-reported gay men, and 3 (1.8%) female sex workers. Significant risk factors for adults were sexual and nonsexual contact with persons who had mpox, as well as risky sexual behavior. For children, risk factors were close contact with an mpox-positive person and prior animal exposure. Odds of being mpox positive were higher for adults with HIV and lower for those co-infected with varicella zoster virus (VZV). No children were HIV-seropositive; odds of being mpox positive were higher for children with VZV infection. Our findings indicate mpox affects primarily adults in Nigeria, partially driven by sexual activity; childhood cases were driven by close contact, animal exposure, and VZV co-infection.

Non-invasive assessment of hepatic fibrosis among patients with chronic hepatitis B virus infection in three tertiary hospitals in Nigeria.

Objective: This study aimed to assess hepatic fibrosis, using noninvasive tests, among patients with chronic hepatitis B virus infection in Nigeria. Methods: The study was a retrospective cross-sectional, hospital-based, multicentered study. The data of adult Nigerians who were aged 18 years and above who had been diagnosed with chronic hepatitis B infection and were not on treatment were extracted from three tertiary health institutions across Nigeria. Sociodemographic and relevant clinical data were obtained from the case notes of the patients. Fibrosis-4 and aspartate aminotransferase platelet ratio index scores were calculated to determine the presence and severity of liver fibrosis in the patients. The data obtained were analyzed using Statistical Package for the Social Sciences (version 25.0). A p-value of less than 0.05 was considered as statistically significant. Results: The data of a total of 234 patients were extracted for this study from across 3 tertiary hospitals in Nigeria. There were 132 (56.4%) males and 102 (43.6%) females in a ratio of 1.29:1 with a mean age of 37.92 ± 12.34 years. The fibrosis-4 score of the patients showed that 62.8% had "Normal/Mild Fibrosis," 25.6% had "Moderate Fibrosis," and 11.5% had "Severe Fibrosis/Cirrhosis." The aspartate aminotransferase platelet ratio index score of the patients showed that 64.1% had "No Fibrosis," 20.9% had "Mild Fibrosis," 6.4% had "Moderate Fibrosis," and 8.5% had "Severe Fibrosis/Cirrhosis." The median fibrosis-4 score of the patients was 1.18 (0.77-1.74), while the median aspartate aminotransferase platelet ratio index score was 0.40 (0.26-0.69). Liver ultrasonography detected cirrhosis in 8.5% of the patients. All the patients were not yet on treatment for hepatitis B infection. Conclusion: The prevalence of hepatic fibrosis is high among patients with chronic hepatitis B virus infection in Nigeria and a large number of these patients were not yet on therapy. Noninvasive assessment of hepatic fibrosis should be considered as a critical part of the work-up of patients with chronic hepatitis B infection.

Assessment of descending aortic blood flow velocities with continuous wave Doppler echocardiography among healthy Children in South East Nigeria.

Background: The descending aorta velocity is important predictor of aortic disease in children and can be very helpful in some clinical and surgical decision making. Aim: The purpose of this study is to assess the normative values of descending aorta velocity among children from South-East Nigeria. It also aimed to assess the correlation between age, body surface area and mean velocity across the descending aorta. Methods: This is a cross-sectional study where the descending aorta velocity of one hundred and eleven children were enrolled consecutively using digitized two-dimensional and Doppler echocardiography. Results: A total of 111 children had echocardiography to study their cardiac structures and compute their mean scores of their descending aorta velocity. The mean velocity across the descending aorta was 1.3±0.2m/s with maximum and minimum velocities of 2.06 and 0.84cm respectively. The mean descending aorta velocity in males (1.37±0.24 m/s) was significantly higher than that in females (1.24±0.18); (Student T test 3.09, p = 0.03). There was no correlation between age and mean velocity across the descending aorta (Pearson correlation coefficient; -0.03, p = 0.7) nor between body surface area and descending aorta velocity (correlation coefficient 0.01, p= 0.8). Conclusions: The presented normalized values of the descending aorta velocity using a digitized two-dimensional and Doppler echocardiography among healthy children will serve as a reference values for further studies and can be applied for clinical and surgical use in children with various cardiac anomalies.

Emerging cancer disease burden in a rural sub-Saharan African population: northeast Nigeria in focus.

Introduction: Sub-Saharan Africa (SSA) is plagued by myriads of diseases, mostly infectious; but cancer disease burden is rising among non-communicable diseases. Nigeria has a high burden of cancer, however its remote underserved culturally-conserved populations have been understudied, a gap this study sought to fill. Methods: This was a cross-sectional multi-institutional descriptive study of histologically diagnosed cancers over a four-year period (January 2019-December 2022) archived in the Departments of Pathology and Cancer Registries of six tertiary hospitals in the northeast of Nigeria. Data obtained included age at diagnosis, gender, tumor site and available cancer care infrastructure. Population data of the study region and its demographics was obtained from the National Population Commission and used to calculate incident rates for the population studied. Results: A total of 4,681 incident cancer cases from 2,770 females and 1,911 males were identified. The median age at diagnosis for females was 45 years (range 1-95yrs), and 56 years (range 1-99yrs) for males. Observed age-specific incidence rates (ASR) increased steadily for both genders reaching peaks in the age group 80 years and above with the highest ASR seen among males (321/100,000 persons) compared to females (215.5/100,000 persons). Breast, cervical, prostatic, colorectal and skin cancers were the five most common incident cancers. In females, breast, cervical, skin, ovarian and colorectal cancers were the top five malignancies; while prostate, haematolymphoid, skin, colorectal and urinary bladder cancers predominated in men. Conclusion: Remote SSA communities are witnessing rising cancer disease burden. Proactive control programs inclusive of advocacy, vaccination, screening, and improved diagnostics are needed.

Sero-Kinship: How Young People Living With HIV/AIDS Survive in Southeast Nigeria.

Research on the lived experiences of HIV survivors, including young people living with HIV, has primarily emphasized broader sociocultural concerns, such as stigmatization and cultural attitudes toward sexuality and gender, while giving less attention to the interconnectedness of these issues with the mental well-being of those affected by the illness. This study, drawing on relational ethnography including observations and interviews at four antiretroviral-administering healthcare facilities in Enugu State, southeast Nigeria, explores how young people living with HIV strive toward viral suppression and how they develop collaborative psychosocial support along with the global efforts in eradicating the HIV epidemic. We found that, in and between themselves, young people living with HIV weave for themselves a network of relationships, though discreetly, to foster and encourage survivorship. Such relatedness, where mutual trust and support have emerged and rebuilt HIV survivors' faith in a livable life, forms what we conceptualize as "sero-kinship." That is, sero-kinship, which focuses on how people create and change meanings in their everyday lives that ultimately contribute to controlling HIV and treatment management, forms an essential foundation on which a life with HIV becomes thinkable, bearable, then manageable, and acceptable.

The comprehensive epidemiological status of human African trypanosomiasis in Nigeria: meta-analysis and systematic review of the full story (1962-2022).

Human African trypanosomiasis (HAT) in Nigeria is caused primarily by Trypanosoma brucei gambiense (gHAT), which has historically been a major human and animal health problem. This study aims to examine the status of gHAT in Nigeria over the past 60 years. The World Health Organization (WHO) set two targets to eliminate HAT as a public health concern by 2020 and terminate its global transmission by 2030. The former target has been achieved, but accurate monitoring and surveillance are important for maintaining this success and delivering the second target. Although recent cases in Nigeria are rare, accurately estimating the national seroprevalence and actual prevalence of gHATs remains challenging. To address this, a meta-analysis reviewed studies on gHATs in Nigeria from databases such as Embase, Global Health, Ovid Medline, Web of Science, and Google Scholar. Ten studies were included, ranging between 1962 and 2016, covering 52 clusters and 5,671,877 individuals, even though databases were scrutinized up to 2022. The seroprevalence ranged from 1.75 to 17.07%, with an overall estimate of 5.01% (95% CI 1.72-9.93). The actual gHAT prevalence detected by parasitological or PCR methods was 0.001 (95% CI 0.000-0.002), indicating a prevalence of 0.1%. Notably, the seroprevalence was greater in southern Nigeria than in northern Nigeria. These findings suggest that the disease might be spreading unnoticed due to the increased movement of people from endemic areas. This study highlights the paucity of studies in Nigeria over the last 60 years and emphasizes the need for further research, systematic surveillance, and proper reporting methods throughout the country.

Bayesian spatial analysis of incomplete vaccination among children aged 12-23 months in Nigeria.

High childhood disease prevalence and under-five mortality rates have been consistently reported in Nigeria. Vaccination is a cost-effective preventive strategy against childhood diseases. Therefore, this study aimed to identify the determinants of Incomplete Vaccination (IV) among children aged 12-23 months in Nigeria. This cross-sectional design study utilized the 2018 Nigeria Demographic and Health Survey (NDHS) dataset. A two-stage cluster sampling technique was used to select women of reproductive age who have children (n = 5475) aged 12-23 months. The outcome variable was IV of children against childhood diseases. Data were analyzed using Integrated Nested Laplace Approximation and Bayesian binary regression models (α0.05). Visualization of incomplete vaccination was produced using the ArcGIS software. Children's mean age was 15.1 ± 3.2 months and the median number of vaccines received was four. Northern regions contributed largely to the IV. The likelihood of IV was lower among women aged 25-34 years (aOR = 0.67, 95% CI = 0.54-0.82, p < 0.05) and 35-49 years (aOR = 0.59, 95%CI = 0.46-0.77, p < 0.05) compared to younger women in the age group 15-24 years. An increasing level of education reduces the risk of odds of IV. Other predictors of IV were delivery at the health facility (aOR = 0.64, 95% CI = 053-0.76, p < 0.05), and media exposure (aOR = 0.63, 95%CI = 0.54-0.79, p < 0.05). Mothers' characteristics explained most of the variability in the IV, relatively to smaller overall contributions from the community and state-level factors (p < 0.05). The level of IV against childhood diseases was high in Nigeria. However, disparities exist across the regions and other socioeconomic segments of the population. More efforts are required to improve vaccination sensitization programs and campaigns in Nigeria.

"You Need to be Able to Stand Up for What is Right": MTV Shuga Naija's Transformative Impact on Youth Attitudes Toward Sexual Violence in Nigeria.

In Nigeria, approximately 10% of women of reproductive age report experiencing sexual violence in the past year, with potentially enduring health and social consequences. The effects can be especially severe for younger women and adolescents. MTV Shuga Naija utilizes an entertainment-education TV serial drama to promote gender equality and challenge norms around sexual violence. Using a two-wave panel survey of Nigerian youth (574 females; 317 males) aged 15 to 24 years, this study explores the impact of MTV Shuga Naija on disclosing experiences of sexual violence, reducing stigma, and fostering dialogue. Baseline data were collected in person, while endline data were collected by telephone due to the COVID-19 pandemic. The survey, informed by the Theory of Planned Behavior (TPB), examined shifts in self-reported sexual harassment and attitudes toward victims of sexual violence. A doubly robust, difference-in-differences (DID) analysis compares changes in outcomes in treatment versus comparison areas, adjusting for observed and unobserved differences and using inverse probability weighting to enhance the precision of impact estimates. DID models show significant attitude shifts and increased disclosure of sexual violence among youth exposed to MTV Shuga Naija. Agreement with victim-blaming statements dropped significantly for both men and women in treatment versus comparison areas. However, contrary to hypotheses, respondents in comparison areas were more likely to discuss sexual violence with family, although the context and content of these discussions could not be examined. This study therefore confirms that MTV Shuga Naija's entertainment-education effectively improves attitudes and behaviors concerning sexual violence. Even so, victim-blaming norms and experiences of sexual violence remain prevalent. While the program has made progress in addressing this sensitive issue in Nigeria, further research is needed to improve family and community dialogues and to enhance support for victims.

Epidemiological trends and treatment abandonment of paediatric solid tumours in a nigerian tertiary hospital: a seven-year review (2016-2022).

BACKGROUND: Paediatric solid tumours, both benign and malignant, present significant health challenges, particularly in Sub-Saharan Africa where comprehensive data is limited. This study aims to elucidate the prevalence, distribution, and treatment outcomes of paediatric solid neoplasms in a tertiary hospital in South-East Nigeria over a seven-year period. METHODS: A retrospective cohort study was conducted at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Clinical details and histological slides of confirmed cases from January 2016 to December 2022 were reviewed. Data extraction focused on socio-demographic variables and treatment outcomes, analysed using statistical methods. RESULTS: The study included 293 children diagnosed with solid tumours (58.1% malignant, 41.9% benign), with a female predominance (61.8%). The median age at diagnosis was 12 years. Fibroadenoma was the most common benign tumour (61.8% of benign cases), while non-Hodgkin lymphoma was the predominant malignant tumour (18.2% of malignant cases). Treatment abandonment rates differed significantly between benign (13.8%) and malignant (51.2%) tumours. Significant associations were found between treatment outcomes and factors such as gender (p = 0.0001 for benign tumours), age category (p = 0.0001 for benign tumours), and specific diagnoses (p = 0.0001 for both benign and malignant tumours). CONCLUSION: This study underscores the substantial burden of paediatric solid tumours in South-East Nigeria and highlights the critical need for improved treatment adherence strategies, particularly for malignant cases. The findings emphasize the importance of tailored interventions based on tumour type, age, and gender. These insights can inform future research, policy formulation, and healthcare strategies aimed at enhancing the management and outcomes of paediatric solid neoplasms in resource-limited settings.

Differences in neutralizing antibody sensitivities and envelope characteristics indicate distinct antigenic properties of Nigerian HIV-1 subtype G and CRF02_AG.

The magnitude of the HIV-1 epidemic in Nigeria is second only to the subtype C epidemic in South Africa, yet the subtypes prevalent in Nigeria require further characterization. A panel of 50 subtype G and 18 CRF02_AG Nigerian HIV-1 pseudoviruses (PSV) was developed and envelope coreceptor usage, neutralization sensitivity and cross-clade reactivity were characterized. These PSV were neutralized by some antibodies targeting major neutralizing determinants, but potentially important differences were observed in specific sensitivities (eg. to sCD4, MPER and V2/V3 monoclonal antibodies), as well as in properties such as variable loop lengths, number of potential N-linked glycans and charge, demonstrating distinct antigenic characteristics of CRF02_AG and subtype G. There was preferential neutralization of the matched CRF/subtype when PSV from subtype G or CRF02_AG were tested using pooled plasma. These novel Nigerian PSV will be useful to study HIV-1 CRF- or subtype-specific humoral immune responses for subtype G and CRF02_AG.

Knowledge, attitude and utilisation of evidence-based therapeutic exercises in knee osteoarthritis management in Nigeria.

Background: In Nigeria, there is a disparity among physiotherapists regarding therapeutic exercise as a core treatment for patients with knee osteoarthritis (OA). The attitudes and beliefs of physiotherapists could influence this. Objective: To investigate Nigerian physiotherapists' knowledge, attitude, and utilisation of evidence-based therapeutic exercises. Design: A mixed-method of cross-sectional survey and focus group discussion. Setting: Secondary and tertiary health institutions in Nigeria. Participants: Physiotherapists consecutively sampled from the selected institutions. Main outcome measures: Participants' knowledge, attitude and utilisation of evidence-based therapeutic exercises for the management of knee OA. Results: This study revealed that 81% of physiotherapists in Nigeria had a fair knowledge of evidence-based practice and the efficacy of therapeutic exercises in managing knee OA. Despite this fair knowledge, 95.3% had a poor attitude. The important emerging categories/themes are treatment preference, clinical experience, and strength of evidence. Conclusion: Physiotherapists in Nigeria have a fair knowledge of evidence-based therapeutic exercises in managing patients with knee OA, although there is a poor attitude and disparity between the use and current recommendations. Funding: The research received no funding from a commercial or non-profit organisation.

Divergent beliefs about food safety and affordability in Nigeria.

Access to safe, affordable diets is paramount for improved nutritional outcomes. Yet, how do stakeholders perceive the binding constraints and requisite policy actions to increase food safety and affordability? Focusing on Nigeria, this paper uses best-worst scaling techniques applied to a survey of 200 government and agrifood system stakeholders to examine their policy beliefs on safety and affordability vis-à-vis the vegetable and fish value chains. We find that divergence among stakeholders is greater for food safety than affordability. While antibiotics overuse and toxin exposure, lack of knowledge, and weak legislation were identified by different stakeholders as the binding constraints for food safety, high costs of inputs and infrastructure, as well as security threats, were seen as common challenges for affordability across most, though not all, stakeholders for both value chains. Overall, the paper highlights the importance of beliefs in the agrifood system policymaking process and emphasizes the need to explore not only the existence but also the source of divergent beliefs among policy actors in greater depth.

Perception, acceptability and challenges of digital adherence technology among TB healthcare workers.

INTRODUCTION: Successful treatment of TB requires high levels of adherence to treatment. This has been found to be below optimal with directly observed therapy (DOT), and digital adherence technologies (DATs) offer a promising approach to non-adherence to medication and improving treatment outcomes. This study explores the perception, acceptability, and challenges of DATs among healthcare workers (HCWs). METHODS: The study was conducted in eight states in Nigeria among Health Care workers involved in treating patients with TB. This was a descriptive cross-sectional study using an open questionnaire and analysed using IBM SPSS v25. RESULTS: Twenty-three HCWs (95.8%) agreed that DATs helped them provide better support and counselling to their patients. All of them would recommend DATs to their patients and found it easy to explain them. Eleven (45.8%) of them were not able to use DATs on a few occasions; their reasons were poor network (n = 9, 37.5%) and (n = 1, 4.2%) power failure. CONCLUSION: DATs help HCWs provide better support and care regarding real-time tracking of their patients' adherence to treatment and possibly reduction of attrition. This implies that DATs are a suitable alternative to DOT to help HCWs provide the best care and support to their patients towards achieving the End TB targets.

INTRODUCTION: Le traitement réussi de la TB nécessite des niveaux élevés d'observance du traitement. Cela s'est avéré inférieur à l'optimal avec le traitement sous observation directe, et les technologies d'observance numérique (DAT) offrent une approche prometteuse de la non-observance des médicaments et de l'amélioration des résultats du traitement. Cette étude explore la perception, l'acceptabilité et les défis des DAT chez les travailleurs de la santé (HCW, pour l'anglais « healthcare worker ¼). MÉTHODES: L'étude a été menée dans huit États du Nigeria auprès de travailleurs de la santé impliqués dans le traitement des patients atteints de TB. Il s'agissait d'une étude transversale descriptive utilisant un questionnaire ouvert et analysée à l'aide d'IBM SPSS v25. RÉSULTATS: Vingt-trois HCW (95,8%) ont convenu que les DAT les aidaient à fournir un meilleur soutien et des conseils à leurs patients. Tous recommandaient les fichiers DAT à leurs patients et trouvaient facile de les expliquer. Onze d'entre eux (45,8%) n'ont pas pu utiliser les fichiers DAT à quelques reprises, en raison d'une mauvaise qualité du réseau (n = 9 ; 37,5%) et d'une panne de courant (n = 1 ; 4,2%). CONCLUSION: Les DAT aident les HCW à fournir un meilleur soutien et des soins en ce qui concerne le suivi en temps réel de l'observance du traitement par leurs patients et éventuellement la réduction de l'attrition. Cela implique que les DAT sont une alternative appropriée au DOT pour aider les travailleurs de la santé à fournir les meilleurs soins et le meilleur soutien à leurs patients pour atteindre les objectifs de l'éradication de la TB.

Clinical students' perception of educational environment in a Nigerian university: a mixed method study.

BACKGROUND: Learning environment (LE) research has been given priority in higher education institutions globally because of its influence on learning processes and outcomes. Although studies reporting the perceptions of health science students about LE in Nigeria are available, none have compared the perceptions of students from different health professions. Therefore, this study aimed to assess final-year clinical students' perceptions of their LE from four programs (dentistry, medicine, nursing, and physiotherapy) and compared their LE perceptions. METHODS: This study adopted a cross-sectional study design using a mixed method approach. The quantitative survey involved all the final-year clinical students at the University of Ibadan, and they completed the Dundee Ready Education Environment Measure (DREEM) questionnaire. The qualitative aspect involved 24 consenting students in four focus group discussions. RESULTS: A total of 214 out of 223 copies of the DREEM questionnaire were duly completed and returned, yielding 96.0% response rate. The participants' mean age was 24 ± 2.3 years (ranged between 22 and 25 years, p = 0.001). The mean DREEM scores of the students from the four programs ranged between 119.68 ± 18.02 and 147.65 ± 15.89 out of a maximum of 200, interpreted as more positive than negative perceptions of LE. Physiotherapy students' DREEM score was significantly higher than those of medical, dental, and nursing students (p < 0.001). The DREEM scores of other students did not differ significantly (p > 0.05). Dental and medical students had similar positive perceptions. The qualitative aspect revealed that the students had positive perceptions of their teachers' knowledge base and self-acquisition of knowledge but negative perceptions of their teachers' communication skills, infrastructural facilities, lecturer-student relationships, and hostel accommodations. CONCLUSION: Although the survey indicated that these clinical students had more positive than negative perceptions of their learning environment, the qualitative aspect of the study revealed many challenges that the students were confronted with. The clinical students' perception of their learning environment could be improved if the university authorities would address these challenges.
