Design, Implementation, and Coordination of Malaria Therapeutic Efficacy Studies in Nigeria in 2018.

Prior to 2018, malaria therapeutic efficacy studies (TESs) in Nigeria were implemented separately at different sites, as assigned by the National Malaria Elimination Program (NMEP). In 2018, however, the NMEP engaged the Nigerian Institute of Medical Research to coordinate the 2018 TESs in 3 of 14 sentinel sites with the objective of standardizing their conduct across all three sites: Enugu, Kano, and Plateau states in three of six geopolitical zones. Artemether-lumefantrine and artesunate-amodiaquine, the two first-line drugs for treatment of acute uncomplicated malaria in Nigeria, were tested in both Kano and Plateau states. In Enugu State, however, artemether-lumefantrine and dihydroartemisinin-piperaquine were the test drugs, with dihydroartemisinin-piperaquine being tested for potential inclusion in Nigerian treatment policy. The TES was conducted in 6-month to 8-year-old children and was funded by the Global Fund with additional support from the WHO. A multipartite core team comprised of the NMEP, the WHO, the U.S. Presidential Malaria Initiative, academia, and the Nigerian Institute of Medical Research was set up to oversee the execution of the 2018 TES. This communication reports best practices adopted to guide its coordination, and lessons learned during in the process, including applying developed standard operating procedures, powering the sample size adequately for each site to report independently, training the investigating team for fieldwork, facilitating stratification of decisions, determining efficiencies derived from monitoring and quality assessment, and optimizing logistics. The planning and coordination of the 2018 TES activities is a model of a consultative process for the sustainability of antimalarial resistance surveillance in Nigeria.

Determinants of infant feeding practices among Black mothers living with HIV: a multinomial logistic regression analysis.

BACKGROUND: Infant feeding practices are imperative for babies' and mothers' health and emotional wellbeing. Although infant feeding may seem simple, the decisions surrounding it are complex and have far-reaching implications for women globally. This is an especially difficult concern among mothers living with HIV because breastfeeding can transmit HIV from mother to child. This is further complicated by cultural expectations in case of Black mothers living with HIV. This paper discusses determinants of infant feeding practices among Black mothers living with HIV who were on anti-retroviral therapy (ART) in two North American cites and one African city. METHODS: A cross-sectional, multi-country survey using venue-based convenience sampling of Black mothers living with HIV was employed. The effective response rates were 89% (n = 89) in Ottawa, Canada; 67% (n = 201) in Miami, Florida, US; and 100% (n = 400) in Port Harcourt, Nigeria, equaling a total sample size of 690. Data were collected in Qualtrics and managed in Excel and SPSS. Multinomial logistic regression analyses were used to determine the factors influencing the mothers' infant feeding practices (Exclusive Formula Feeding [EFF] = 1; Mixed Feeding [MF] = 2; and Exclusive Breastfeeding [EBF while on ART] =3). RESULTS: The results highlight socio-demographics, EFF determinants, and EBF determinants. The statistically significant determinants of infant feeding practices included national guideline on infant feeding, cultural beliefs and practices, healthcare systems, healthcare personnel, infant feeding attitudes, social support, and perceived stress. Mothers' mean ages were Ottawa (36.6 ± 6.4), Miami (32.4 ± 5.8), and Port Harcourt (34.7 ± 5.7). All sampled women gave birth to least one infant after their HIV diagnoses. Statistically significant (p < .05) determinants of EFF relative to MF were the national guideline of EFF (relative risk [RR] = 218.19), cultural beliefs (RR = .15), received healthcare (RR = 21.17), received healthcare through a nurse/midwife (RR = 3.1), and perceived stress (RR = .9). Statistically significant determinants of EBF relative to MF were received healthcare (RR = 20.26), received healthcare through a nurse/midwife (RR = 2.31), functional social support (RR = 1.07), and perceived stress (RR = .9). CONCLUSION: While cultural beliefs and perceived stress favoured MF over EFF, advice of healthcare workers, and the care received from a nurse/midwife improved EFF over MF. Also while the mothers' perceived stress favoured MF over EBF, advice of their nurses or midwife and the social support improved EBF over MF. The providers advice was congruent with WHO and national guidelines for infant feeding among mothers living with HIV. These results have implications for nursing, healthcare practice, and policies on infant feeding practices for mothers living with HIV.

Motherhood among Black women living with HIV: A "north-south" comparison of sociocultural and psychological factors.

We compared factors mediating motherhood experiences among Black nursing mothers living with HIV in two North American cities to one African city. Motherhood was measured with the Being a Mother Scale, and we compared their predictors between the two continents using difference in difference estimation within hierarchical linear modeling. Cultural beliefs congruent with infant feeding guidelines and social support had significant positive but differing effects on motherhood in the two continents. Perceived stress had significant negative impact on motherhood in the two continents. Due considerations to sociocultural contexts in policy development, HIV interventions and education of health care providers were recommended.

Determinants of Adherence to National Infant Feeding Guidelines by Black Mothers Living with HIV.

Objective: Worldwide, 160,000 children were newly infected with HIV in 2018; half of these were infected through breastfeeding. Infant feeding guidelines are distinct depending on each country's resources and national or sub-national guidelines. Because of divergent guidelines, the best infant feeding approach to prevent mother-to-child transmission can become unclear. The purpose of this study was to examine the sociocultural and psychosocial factors related to adherence to infant feeding guidelines through a city-level, North-South comparison of Black mothers living with HIV in Nigeria, Canada, and the United States. Design: Using a cross-sectional multi-country survey, a convenience sample of 690 mothers were recruited from June 2016 - December 2019. Socio-cultural and psychosocial factors influencing infant feeding practices were measured. Results: Using binary logistic regression, infant feeding attitudes (OR = 1.10), motherhood experiences (OR = 1.08), low hyper-vigilance score (OR = .93), paternal support (OR = 1.10) and perception that the health care provider supported adherence to infant feeding guidelines (OR = 2.43) were associated with guideline adherence. Mothers who had cultural beliefs that were inconsistent with infant feeding guidelines and mothers with low incomes (OR = 2.62) were less likely adherent with their country's guidelines. Conclusion: City-level factors were not found to influence adherence to infant feeding guidelines; however, socio-cultural and psychosocial factors at community, family and individual levels were significant. Policy formulation and targeted interventions must be cognizant of cultural expectations of motherhood and mindful of psychosocial determinants of adherence to infant feeding guidelines.

Infant feeding guideline awareness among mothers living with HIV in North America and Nigeria.

BACKGROUND: WHO guidelines recommend breastfeeding for mothers living with HIV adherent to antiretroviral therapy in countries where formula is not accessible. In Canada and the US, guidelines for mothers living with HIV recommend exclusive formula feeding. Awareness of national infant feeding guidelines and socio-cultural factors influence infant feeding choices that may result in an increased risk of vertical transmission of HIV. The purpose of this paper is to present factors associated with awareness of guidelines among Black mothers living with HIV. Data were derived from a survey conducted as part of a recent international study that examined infant feeding practices among Black women living with HIV in Ottawa, Canada; Port Harcourt, Nigeria; and Miami, Florida. METHODS: Participants (n = 690) from Port Harcourt (n = 400), Miami (n = 201), and Ottawa (n = 89) were surveyed on their awareness of infant feeding guidelines for mothers living with HIV. Data were collected between November, 2016 and March, 2018. RESULTS: Participants' mean ages were 34.3 ± 5.9 years. Across all sites, 15.4% (95% CI 13.2, 7.7) of mothers were NOT aware of their country's infant feeding guidelines. Cultural beliefs (OR = 0.133, p = 0.004, 95% CI 0.03, 0.53) and functional social support influenced infant feeding choices (OR = 1.1, p = 0.034, 95% CI 1.01, 1.20) and were statistically significant predictors of guideline awareness (Χ2 = 38.872, p < .05) after controlling for age, years of formal education, marital status, and country of residence. As agents of functional social support, family members and health workers (e.g., nurses, physicians, social workers, other health care workers) influenced participants' awareness of infant feeding guidelines and guided them in their infant feeding choices. CONCLUSIONS: Among participants, awareness of national infant feeding guidelines was associated with functional social support and cultural beliefs influenced infant feeding choices. Therefore, culturally adapted messaging via social supports already identified by mothers, including family relationships and health workers, is an appropriate way to enhance awareness of infant feeding guidelines. Ultimately, contributing to the global health goals of maternal health and reduced infant mortality.

HIV-Related Stigma Among Black Mothers in Two North American and One African Cities.

HIV-related stigma is a negative attitude or behaviour towards persons living with HIV, and is detrimental to effective care, management, and treatment of HIV. Using a revised 10-item stigma scale, we compared levels of HIV-related stigma and its correlates among Black women living with HIV in Ottawa, Canada, and Miami, FL, USA, with those in Port Harcourt, Nigeria. HIV-related stigma scores were calculated, with a maximum score of 10 and averaged 4.71 in Ottawa, 5.06 in Miami, and 3.78 in Port Harcourt. No significant difference in HIV-related stigma scores between Ottawa and Miami. HIV-related stigma was significantly (p < 0.05) higher among women in the North American cities compared with women in the African city. Hierarchical linear modelling shows that psychosocial variables contributed to variations in HIV-related stigma in Ottawa (22.3%), Miami (36.3%), and Port Harcourt (14.1%). At p < 0.05, discrimination was a significant predictor of increased HIV-related stigma in Ottawa (ß = 0.077), Miami (ß = 0.092), and Port Harcourt (ß = 0.068). Functional social support had a significant diminishing effect on HIV-related stigma in Miami (ß = - 0.108) and Port Harcourt (ß = - 0.035). Tackling HIV-related sigma requires sociocultural considerations within specific regional and national contexts.

Sociocultural factors influencing infant-feeding choices among African immigrant women living with HIV: A synthesis of the literature.

BACKGROUND AND PURPOSE: The World Health Organizations (WHO) strategy is to eliminate pediatric HIV. HIV prevention guidelines in high-income countries recommend mothers living with HIV avoid breastfeeding. Yet, breastfeeding is promoted as the normal and unequalled method of feeding infants. This creates a paradox for mothers coming from cultures where breastfeeding is an expectation and formula feeding suggests illness. Therefore, the purpose of this literature review is to examine the context influencing infant feeding among African immigrant women living with HIV to develop interventions to reduce the risk of HIV mother-to-child transmission. METHODS: Using the PEN-3 cultural model as a guide, we selected 45 empirical studies between 2001 and 2016 using 5 electronic databases on the sociocultural factors influencing infant-feeding choices and practices among African women from HIV endemic countries. CONCLUSIONS: Findings are congruent with the importance of culture when developing guidelines. Our review provides support that culture-centered interventions are crucial toward achieving the WHO's strategy to eliminate pediatric HIV. IMPLICATIONS FOR PRACTICE: Understanding the sociocultural determinants of infant-feeding choices is critical to the development of prevention initiatives to eliminate pediatric HIV.

Private sector malaria RDT initiative in Nigeria: lessons from an end-of-project stakeholder engagement meeting.

The malaria rapid diagnosis testing (RDT) landscape is rapidly evolving in health care delivery in Nigeria with many stakeholders playing or having potential for critical roles. A recent UNITAID grant supported a pilot project on the deployment of quality-assured RDTs among formal and informal private service outlets in three states in Nigeria. This paper describes findings from a series of stakeholder engagement meetings held at the conclusion of the project. The agreed meeting structure was a combination of plenary presentations, structured facilitated discussions, and nominal group techniques to achieve consensus. Rapporteurs recorded the meeting proceeding and summaries of the major areas of discussion and consensus points through a retrospective thematic analysis of the submitted meeting reports. Key findings indicate that private providers were confident in the use of RDTs for malaria diagnosis and believed it has improved the quality of their services. However, concerns were raised about continued access to quality-assured RDT kits. Going forward, stakeholders recommended increasing client-driven demand, and continuous training and supervision of providers through integration with existing monitoring and supervision mechanisms.

Status of the use and compliance with malaria rapid diagnostic tests in formal private health facilities in Nigeria.

BACKGROUND: Nigeria has the largest number of malaria-related deaths, accounting for a third of global malaria deaths. It is important that the country attains universal coverage of key malaria interventions, one of which is the policy of universal testing before treatment, which the country has recently adopted. However, there is a dearth of data on its implementation in formal private health facilities, where close to a third of the population seek health care. This study identified the level of use of malaria rapid diagnostic testing (RDT), compliance with test results and associated challenges in the formal private health facilities in Nigeria. METHODS: A cross-sectional study that involved a multi-stage, random sampling of 240 formal private health facilities from the country's six geo-political zones was conducted from July to August 2014. Data were collected using health facility records, healthcare workers' interviews and an exit survey of febrile patients seen at the facilities, in order to determine fever prevalence, level of testing of febrile patience, compliance with test results, and health workers' perceptions to RDT use. RESULTS: Data from the 201 health facilities analysed indicated a fever prevalence of 38.5% (112,521/292,430). Of the 2077 exit interviews for febrile patients, malaria testing was ordered in 73.8% (95% CI 71.7-75.7%). Among the 1270 tested, 61.8% (719/1270) were tested with microscopy and 38.2% (445/1270) with RDT. Compliance to malaria test result [administering arteminisin-based combination therapy (ACT) to positive patients and withholding ACT from negative patients] was 80.9% (95% CI 78.7-83%). Compliance was not influenced by the age of patients or type of malaria test. The health facilities have various cadres of the health workers knowledgeable on RDT with 70% knowing the meaning, while 84.5% knew what it assesses. However, there was clearly a preference for microscopy as only 20% reported performing only RDT. CONCLUSION: In formal private health facilities in Nigeria there is a high rate of malaria testing for febrile patients, high level of compliance with test results but relatively low level of RDT utilization. This calls for improved engagement of the formal private health sector with a view to achieving universal coverage targets on malaria testing.

Prevalence and risk factors for stroke in an adult population in a rural community in the Niger Delta, south-south Nigeria.

Sub-Saharan Africa is experiencing an epidemiologic transition with stroke contributing to the disease burden. However, community-based stroke prevalence studies are sparse. This study aimed to determine the prevalence of stroke in a rural population in the Niger Delta region in south-south Nigeria and to describe known risk factors for stroke among them. A door-to-door stroke prevalence study was conducted in 2008 among randomly selected adults of 18 years or older in rural Kegbara-Dere community in Rivers State, south-south Nigeria. We administered a modified screening tool by the World Health Organization, a stroke-specific questionnaire, and conducted a physical/neurological examination (on persons screening positive) in 3 stages of assessments. The crude prevalence of stroke was 8.51/1000 (95% confidence interval [CI] = 3.9-16.1) representing 9 of 1057 participants. The age-adjusted prevalence was 12.3/1000 using the US Population 2000. Men had higher unadjusted prevalence than women (12.9/1000 versus 5.1/1000) but were not at more risk (unadjusted relative risk = .99; 95% CI = .98-1.00). Stroke prevalence increased with age (Mantel-Haenszel χ(2) P = .00). Hypertension (blood pressure ≥140/90 mm Hg) was present in all stroke cases and diabetes mellitus (fasting blood sugar >126 mg/dL) in 1 person, but none had hypercholesterolemia, obesity (body mass index >30 kg/m(2)), or a history of alcohol intake or smoking. Stroke prevalence was found to be high, commoner among men and the elderly population, and likely to be predisposed by hypertension, in rural south-south Nigeria. The need to conduct follow-up studies on the burden and outcomes of stroke among this study population is acknowledged.

Prevalence of hypertension in Kegbara-Dere, a rural community in the Niger Delta region, Nigeria.

OBJECTIVES: Hypertension has become a major health burden in sub-Saharan Africa, mainly due to urbanization and Western acculturation. We investigated the prevalence of hypertension and risk factors in a rural community in South-South Nigeria. DESIGN, SETTING, PARTICIPANTS: Blood pressure and anthropometric indices were measured during a cross-sectional study of community health status among 1078 adults, aged > or = 18 years, in 2008. Information on lifestyle was also collected through structured interviews. STATISTICS: Unadjusted hypertension prevalence was calculated against selected risk factors, and association was demonstrated using risk ratios with 95% confidence intervals. Chi-square was used to test for statistical significance at P < .05. Adjusted analysis was done for age by direct standardization using a reference population. MAIN OUTCOME MEASURE: Prevalence of hypertension, defined as systolic and diastolic blood pressure > or = 140 mm Hg and > or = 90 mm Hg respectively and/or current use of antihypertensive medication. RESULTS: Crude prevalence of hypertension was 18.3% (95% CI = 16.0-20.7), while the age-adjusted prevalence was 2.63% (95% Cl = 2.59-2.66). Hypertension rate increased with age (RRs > 2.0, P = .00) and was higher in those married (RR = .35, P = .00), but showed no sex difference (RR = 1.13, P = .34). Hypertension was associated with tobacco chewing/ snuffing (RR = 2.32, P = .05) and history of diabetes (RR = 3.36, P = .00); but central obesity, alcohol intake, cigarette smoking, and family history of hypertension or diabetes showed no valid association. CONCLUSIONS: The study found a high prevalence of hypertension in a rural community. Although, the influence of selected risk factors could not be established, screening and health promotion in rural areas should be intensified.

Status of emergency obstetric care in a local government area in south-south Nigeria.

This study assessed the status of the availability and performance of emergency obstetric care (EmOC) in 12 functional public health facilities out of the existing 19 in Gokana Local Government Area of Rivers State in south-south Nigeria, prior to the midwives service scheme (MSS) launch in 2009. No facility qualified as basic EmOC, while one had comprehensive EmOC status. Signal functions that required supply of medical consumables were performed by more facilities than services that required special training, equipment and maintenance. Only two facilities (16.67%) had the minimum requirement of > or =4 midwives for 24-hour EmOC service; while only 2.2% of expected births occurred at the facilities. The poor state of maternal health resources in the study area requires urgent interventions by Local and State Governments for infrastructure upgrade and deployment and training of staff towards attainment of MDG-5. A follow-up evaluation would be required since the commencement of the MSS.

Diabetes, hand and/or foot ulcers: a cross-sectional hospital-based study in Port Harcourt, Nigeria.

OBJECTIVE: The study aimed to establish the prevalence of diabetes mellitus and the pattern of diabetic hand and foot ulcers in hospitalized adult patients in a teaching hospital in Port Harcourt, Nigeria. RESEARCH DESIGN AND METHODS: All medical admission at the University of Port Harcourt Teaching Hospital between January 2000 and April 2001 were included in this cross-sectional study. Diabetes mellitus was diagnosed based on a fasting venous plasma glucose >or=7.0 mmol/l or a 2-h post-prandial venous plasma glucose level of >or=11.1 mmol/L using the glucose oxidase method. Data was processed for the 60 diabetic patients with limb ulcers excluding ulcers from major trauma. RESULTS: The prevalence of diabetes mellitus was 38.1% (95% CI=34.8-41.4) among medical in-patients; while hand and foot ulcer was 19.1% among diabetic patients. The left lower limb ranked highest in ulcer involvement (32/60); hand ulcers were found in 5 cases (8.3%). Twenty (33.3%) of the patients had a previous limb ulcer. In 31 patients (51.7%) the ulcers evolved spontaneously without an identifiable cause (p-value=0.00). By Wagner's Grading System, Grade III lesions ranked highest (21/64). CONCLUSIONS: A high prevalence of hand and foot ulcers was confirmed among patients with diabetics, which are common indications for hospitalization, and usually associated with long hospital stay with adverse outcomes including amputation and death. Diabetes education needs to be stepped-up, with emphasis on foot care and early presentation to hospital in the event of limb ulceration.

Type 2 diabetes in adult Nigerians: a study of its prevalence and risk factors in Port Harcourt, Nigeria.

OBJECTIVES: This study aimed to assess the prevalence rates of type 2 diabetes and to determine potential associated risk factors of the disease in Port Harcourt, Nigeria. RESEARCH DESIGN AND METHODS: Five hundred and two (502) subjects aged above 40 years, obtained by a two-stage cluster sampling technique participated in this survey. Casual (random) plasma glucose estimations were done for all subjects after relevant personal data were obtained. Subjects with casual plasma glucose (CPG) > or =7.0 mmol/l had oral glucose tolerance tests (OGTT) done. Fasting and 2 h post glucose load blood samples were analyzed for plasma glucose levels. RESULTS: Thirty-four (34) subjects had diabetes, giving a crude prevalence rate of 6.8% (CI=4.6-9.0%), and standardized rate of 7.9%. The crude prevalence rates were 7.7 and 5.7% for males and females, respectively. Of the 34 diabetic subjects seen, 14 (41.2%) of them were not previously known to have diabetes; 83.7% of these were asymptomatic. Body mass index (BMI) > or = 25 kg/m2 and WHR > or = 0.85, family history of diabetes, physical inactivity, heavy consumption of alcohol, older age as well as high social status and Hausa-Fulani or Ibibio origin were associated with significantly higher prevalence of type 2 diabetes. CONCLUSION: The prevalence of type 2 diabetes in Port Harcourt is relatively high. Changing lifestyle associated with industrialization may explain this. A significant proportion of the diabetic subjects are asymptomatic and undiagnosed. The risk factors as shown in our study clearly emphasize the point that type 2 diabetes is to a large extent a preventable disease.
