Evidence-Based Design Process for Nutrition-Sensitive Agriculture Interventions: A Case Study of the Advancing Local Dairy Development Programme in Nigeria

BACKGROUND

Nigeria is a significant contributor to the global burden of chronic undernutrition in children under 5 years of age. The undernutrition challenge constrains the productivity of rural households. This study was carried out among beneficiaries of the productivity-enhancing Nigerian Dairy Development Programme (NDDP) to guide incorporation of nutrition into the successor program-Advancing Local Dairy Development in Nigeria (ALDDN). Therefore, this study contributes to the literature about operationalizing nutrition-sensitive agricultural frameworks.

OBJECTIVE

The study sought to determine potential entry points for improving the nutrition of smallholder dairy farmers (≤ 5 milk cows) with a focus on food system entry points.

METHODS

Primary data were collected from 514 smallholder dairy households in Oyo and Kano states of Nigeria. Both quantitative and qualitative data were collected. Quantitative data collected included minimum dietary diversity for women, nutrition status, and socioeconomic characteristics of households. Qualitative data included information about sources of food, markets, and other food system characteristics. Quantitative data were analysed using descriptive statistical tools and correlation analysis, while common themes were identified from qualitative data.

CONCLUSIONS

The study showcased men's important role in food purchase and consumption, particularly in Kano. Increasing opportunities and the ability of women to use nutrition education appeared necessary for translating knowledge into improved practices. The own consumption (i.e., the portion of the milk kept for households' consumption as well as diversification of foods produced for consumption); income; women's empowerment; and environmental sanitation pathways seemed to be the most feasible pathways for improving nutrition within the context of the study population.

Training to Build Nutrition Capacity in the Nigerian Agricultural Sector: Initial Assessment and Future Directions

BACKGROUND

In response to calls to increase nutrition-sensitive agriculture (NSA), the Federal Ministry of Agriculture and Rural Development developed the Nigeria Agricultural Sector Food Security and Nutrition Strategy 2016-2025 (AFSNS). Capacity development activities to facilitate the AFSNS implementation subsequently commenced.

OBJECTIVE

This study analyzed the processes and outputs of initial capacity development efforts, examined findings from the analysis using existing literature, and identified critical next steps for nutrition capacity development in the Nigerian agriculture sector.

METHODS

The study reviewed documents including a proposal for nutrition training of agriculture sector actors, reports of meetings held among 6 resource persons who designed and/or delivered training, training reports, participants' pre- and posttraining assessments, and participants' training evaluation. Interviews were conducted with 2 resource persons involved in training design and delivery. Documents and interviews were coded and analyzed to identify emergent themes. Participants' pre- and posttests results were compared using paired t test in Stata 12.0.

RESULTS

Knowledge and practice gaps were more extensive than had been anticipated. Training had some but limited effects on knowledge scores at the federal level. Modules addressing implementation practices had to be scaled down for participants to keep up with the learning pace. Existing literature indicates that such training would have been better planned as part of a broader sectoral nutrition workforce strategy, to facilitate greater tailoring of training to participants' job roles.

CONCLUSION

Effective AFSNS implementation requires developing and operationalizing a comprehensive short-, medium- and long-term Agriculture Sector Nutrition Capacity Development Strategy for Nigeria.

Advancing a Multisectoral Platform for Nutrition-Sensitive Agriculture in Nigeria: Reflections on Effectiveness and Lessons Learned

BACKGROUND

Inadequate coordination mechanisms and capacity to coordinate are limiting factors for maximizing the ability of agriculture to improve nutrition in Sub-Saharan Africa. Effective coordination requires the availability of a platform for stakeholder convening, planning, operationalization of ideas, communication, and accountability. Nigeria's Federal Ministry of Agriculture and Rural Development established one such platform to support the institutionalization of nutrition-sensitive agriculture. Platform members include several departments within the Ministry, other ministries, and development partners. While the platform achieved key milestones and fostered collaboration, some gaps remained.

OBJECTIVE

This study reports an assessment to understand the perspectives of members of the coordination platform and identify ways of increasing effectiveness.

METHODS

Desk reviews of relevant documents and 18 key informant interviews were conducted. Documents and interview notes were coded and analysed to identify recurring themes. Themes were appraised using a nutrition coordination framework.

RESULTS

Sufficiently understanding the nutrition role of representatives' own organization/department and the purpose of the coordination platform and its activities was important for success. The profile and seniority of representing officers also mattered. While the leadership of the Ministry was committed to advancing nutrition through agriculture, the coordination platform could improve its functionality through consistent leadership, increased seniority of member representatives, and appropriate communication.

CONCLUSIONS

Multisectoral coordination platforms are necessary but do not alone achieve nutrition coordination. Effective leadership and investments in time, strategic orientation, and training are critical to achieving a shared purpose, individual sector fulfilment of nutrition roles, and additional coordination success factors.

Fostering an Enabling Environment for Nutrition-Sensitive Agriculture and Food Systems in Nigeria

BACKGROUND

Although recommendations exist for making agriculture and food systems nutrition sensitive, guidance about how to successfully operationalize these recommendations within national institutions is limited. Over the 13 years from 2010 to 2023, there were several undertakings to strengthen the enabling environment for sustainable nutrition-sensitive agriculture (NSA) and food systems in Nigeria. Some studies were also conducted over the period to foster better understanding of the national enabling environment and facilitate effective actions.

OBJECTIVE

This article documents successes and failures from Nigeria's experiences by reflecting on critical developments, events, policies, and programmes on Nigeria's journey toward advancing nutrition through agriculture and food systems; as well as findings from conducted studies.

DISCUSSION

Successes include the existence of a Nutrition and Food Safety Division in the Ministry of Agriculture and an approval for a Nutrition Department, existence of an agriculture sector nutrition strategy, increased private sector engagement and commitment to nutrition-sensitive food systems, and increased funding for nutrition in the agriculture sector. Challenges especially remain for scaling up strategic, operational, and delivery capacity of both organizations and individuals involved in advancing NSA and food systems. Lessons learned include-institutionalizing NSA and food systems takes time; knowledge brokering is indispensable and requires several collaborating entities and stakeholders; and approaches used should be suited to available government capacity.

CONCLUSION

More than a decade of efforts targeting different enabling environment factors has resulted in greater political commitment for nutrition within the agriculture sector and an improved enabling environment for NSA and food systems.

Nutrition Capacity Assessment of Agriculture Extension Services in Nigeria

BACKGROUND

Achieving meaningful malnutrition reductions in Nigeria and other high-burden countries requires sustained improvements in diets, mediated through nutrition-sensitive agriculture and food systems. Yet, the capacity to design, plan, implement, and monitor such nutrition-sensitive systems is very limited, including within agricultural extension services delivery. Understanding existing capacity of actors required to implement nutrition change is crucial for effective capacity development.

OBJECTIVE

This study assessed the nutrition capacity of agriculture extension agents (AEAs) in Nigeria and the capacity of their organizations and the institutions within which they operate.

METHODS

The study assessed 31 extension training materials for inclusion of recommendations for nutrition-sensitive agriculture. Structured interviews and focus group discussions were conducted with 23 extension agents and were coded and analyzed for major themes.

RESULTS

Training materials hardly included nutrition objectives and or nutrition-related services to be delivered. Some nutrition-related services were being delivered, including promotion of biofortified crops and nutrient-dense crops and animals, home gardening, food safety, and dietary diversification. However, these services were limited, and service delivery was unstructured, nonuniform, and inconsistent. Numbers of AEAs are quite inadequate while available AEAs had high workloads, are poorly motivated, and had limited funding, supervision, and logistics capacity to perform roles. Physical security was also a challenge for service delivery. Further, complementary activities in other sectors that were necessary for adequate delivery of nutrition-sensitive agriculture did not always exist.

CONCLUSION

Extensive development of nutrition capacities of extension agents appears unlikely to achieve nutrition-related changes if limiting institutional and organizational capacity deficits are not addressed.

PLAIN LANGUAGE TITLE

Capacity of Agriculture Extension Agents in Nigeria to Deliver Nutrition Services.

PLAIN LANGUAGE SUMMARY

Reducing the significant burden of malnutrition in Nigeria requires increased availability and consumption of foods that are nutritious and free from harmful substances. To produce such foods, farmers need adequate nutrition and food safety knowledge and skills. The production of such food will also need to support nutrition in other ways, including increased women's empowerment. Extension agents traditionally support farmers to adopt new methods of food production and/or processing that support increased food yields. These agents can also be used to deliver services that will address nutrition if they have the necessary knowledge and skills. This study assessed the capacity of agriculture extension agents in Nigeria to deliver nutrition services, in order to determine how to increase their capacity to deliver these services. The results from the study are that the extension agents do not have sufficient knowledge and skills to deliver nutrition services, and that their organizations and the wider context in which they work do not have the capacity to enable them to deliver nutrition services effectively. For instance, the organizations do not have sufficient numbers of staff and do not provide current staff with adequate means of transportation to visit farmers. Insecurity is high and so extension agents are unable to visit farmers frequently because of the potential threats to their lives. The study concludes that effectively using extension agents to deliver nutrition services will require not just training of the extension agents but also improvements in organizational capacity and contextual factors.

Government Budget for Nutrition-Sensitive Agriculture in Nigeria Increased Following Development of Related Strategy

BACKGROUND

Financial resources that are commensurate with the magnitude of malnutrition problem are requisite for effective interventions to reduce malnutrition. Understanding the amount and nature of sectoral investments in nutrition is important for advocating and mobilizing increased government budgetary allocations and release.

OBJECTIVE

This study assessed trends in Nigeria's agriculture sector nutrition allocations and whether launch of nutrition-sensitive agriculture strategy and/or the COVID-19 pandemic may have affected these nutrition allocations.

METHODS

Agricultural budgets from 2009 to 2022 of Nigeria's federal government were analyzed. Nutrition-related budget lines were identified using a keyword search and were then classified as nutrition-specific, nutrition-sensitive, or potentially nutrition-sensitive, based on defined criteria. Potentially nutrition-sensitive items were further screened. Budget lines finally included as nutrition allocations directly targeted improvements in nutrition or intermediate outcomes in pathways between agriculture and nutrition. Budget lines were summed, and these nominal values were adjusted for inflation (using the consumer price index for each year) to obtain real values.

RESULTS

Nutrition allocations in the agriculture budget increased considerably even after adjusting for inflation and went from 0.13% of agriculture capital budget in 2009 to 2.97% in 2022; while the real value of total government agricultural budget declined. Large budgetary increases coincided with the development/launch of costed strategies with nutrition-sensitive agriculture components. Still, there were some missed opportunities to increase nutrition allocations.

CONCLUSIONS

Existence of nutrition-sensitive agriculture strategies has facilitated increased nutrition funding and improved the enabling environment. There is need to optimize existing nutrition allocations while advocating for additional funds.

Stakeholders, Relationships, and Coordination: 2015 Baseline Study of Needed Enablers for Bridging Agriculture-Nutrition Gaps in Nigeria

BACKGROUND

Renewed efforts by the Nigerian government to address malnutrition have led to nutrition actions by several sectors, including the agriculture sector. However, the success of these actions depends on the characteristics of the stakeholders involved, including their relationships and coordination.

OBJECTIVE

This article reports a 2015 study of nutrition-sensitive agricultural stakeholders in Nigeria that assessed what the stakeholders do, where they work and how they are organized to improve nutrition. The study provides a baseline for assessing progress and measuring stakeholder and coordination changes in the Nigerian nutrition-sensitive agriculture landscape.

METHODS

Semi-structured interviews (n = 17) and focus group discussions (n = 2) were held with federal, state, and local government level stakeholders; reviews of stakeholder program documents were also conducted.

RESULTS

The study identified 7 groups of nutrition-sensitive agriculture stakeholders and several coordination challenges. Political leadership, advocacy and provision of material and human resource support by nongovernmental organizations, and donor interest and funding have been vital for mobilizing nutrition-sensitive agriculture. Still, although stakeholders frequently highlighted that nutrition was an important consideration in their interventions, nutrition goals and activities and/or indicators to measure outcomes were not regularly communicated. Also, while coordination mechanisms existed, there appeared to be minimal actual cross-sectoral partnerships because of inadequate trust, competition, and conflicts over institutional turf and mandates.

CONCLUSIONS

Needed enablers for improving nutrition-sensitive agriculture in Nigeria included improved stakeholder nutrition literacy, as well as enhanced stakeholder engagement facilitated by role definition, clarification, and consensus. Exploring different approaches to coordination may also be necessary.

Concordance and determinants of mothers' and children's diets in Nigeria: an in-depth study of the 2018 Demographic and Health Survey

OBJECTIVES

Improving the diversity of the diets in young children 6-23 months is a policy priority in Nigeria and globally. Studying the relationship between maternal and child food group intake can provide valuable insights for stakeholders designing nutrition programmes in low-income and middle-income countries.

DESIGN

We examined the relationship between maternal and child dietary diversity among 8975 mother-child pairs using the Nigeria 2018 Demographic and Health Survey (DHS). We assessed concordance and discordance between maternal and child food group intake using the McNemar's χ² test, and the determinants of child minimum dietary diversity (MDD-C) including women MDD (MDD-W) using hierarchical multivariable probit regression modelling.

SETTING

Nigeria.

PARTICIPANTS

8975 mother-child pairs from the Nigeria DHS.

PRIMARY AND SECONDARY OUTCOME MEASURES

MDD-C, MDD-W, concordance and discordance in the food groups consumed by mothers and their children.

RESULTS

MDD increased with age for both children and mothers. Grains, roots and tubers had high concordance in mother-child dyads (90%); discordance was highest for legumes and nuts (36%), flesh foods (26%), and fruits and vegetables (39% for vitamin-A rich and 57% for other). Consumption of animal source food (dairy, flesh foods, eggs) was higher for dyads with older mothers, educated mothers and more wealthy mothers. Maternal MDD-W was the strongest predictor of MDD-C in multivariable analyses (coef 0.27; 95% CI 0.25 to 0.29, p<0.000); socioeconomic indicators including wealth (p<0.000), mother's education (p<0.000) were also statistically significant in multivariable analyses and rural residence (p<0.000) was statistically significant in bivariate analysis.

CONCLUSION

Programming to address child nutrition should be aimed at the mother-child dyad as their food consumption patterns are related and some food groups appear to be withheld from children. Stakeholders including governments, development partners, non-governmental organizations, donors and civil society can act on these findings in their efforts to address undernutrition in the global child population.

Changes in Nigeria’s enabling environment for nutrition from 2008 to 2019 and challenges for reducing malnutrition

Key 2025 global nutrition targets are unlikely to be met at current rates of progress. Although actions necessary to reduce undernutrition are already mostly known, knowledge gaps remain about how to implement these actions in contextually appropriate ways, and at scales commensurate with the magnitude of the problem. This study describes the nutrition enabling environment in Nigeria, a country that contributes significantly to the global undernutrition burden, and identifies potential entry points for improving the enabling environment that could facilitate implementation and scale-up of essential intervention coverage. Study data were obtained from two sources: content analysis of 48 policies/strategies from agriculture, economic, education, environment, health, nutrition, and water/sanitation/hygiene sectors; and interviews at federal level (16) and in two states (Jigawa (10) and Kaduna (9) States). The study finds that aspects of the enabling environment improved between 2008 and 2019 and facilitated improvements in implementation of nutrition-specific and nutrition-sensitive interventions. Enabling environment components that improved included the framing of nutrition as a multisectoral issue, nutrition advocacy, political attention, evidence around intervention coverage, civil society involvement, and activity of nutrition champions. These factors have been especially important in creating and sustaining momentum for addressing malnutrition. While challenges remain in these aspects, greater challenges persist for factors needed to convert momentum into improvements in nutrition outcomes. Research and data that facilitate shared understanding of nutrition; improved multisectoral and vertical coordination; increased and improved delivery and operational capacity; and increased resource mobilization will be especially important for achieving future progress in nutrition in Nigeria.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study

BACKGROUND

No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge.

METHODS

The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing.

FINDINGS

2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters.

INTERPRETATION

The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Prevalence, Correction Coverage, Unmet Need and Impact on the Quality of Life of Presbyopia among Market Traders in Ibadan, Nigeria

Presbyopia is an age-related condition that results from the gradual decline in accommodation leading to inability to focus at near distances. This study sought to determine the prevalence, correction coverage, unmet need and impact on the quality of life of presbyopia among Bodija market traders in Ibadan, Nigeria. A cross sectional study was conducted on 314 participants aged 35 years and older selected by a non-probability sampling method. Their near vision was tested and corrected to the nearest diopter. Presbyopia was defined as being able to read the N8 optotype at a distance of 40 cm after correction with plus lens of at least one diopter. The prevalence of presbyopia was 46.8% (95% CI: 41.20, 52.5). The prevalence was significantly higher in those aged 50 years or more (95% CI: 2.98, 7.77), in females (95% CI: 1.45, 3.64) and in individuals with no formal education (95%CI: 3.32, 10.91). The presbyopia correction coverage was 29.9% and unmet need was = 70.1%. The major barriers reported as reasons for not obtaining near vision spectacles were lack of money and spectacles not being a priority. Presbyopes reported more difficulty with near work (p<0.001). The prevalence of presbyopia in Bodija market is relatively low compared to other reports with major risk factors being increasing age, female gender and no formal education. Presbyopia correction coverage is low with high unmet need it is important to create awareness and provide affordable and accessible near vision spectacles for those in need.

Coordinating Nigeria's micronutrient deficiency control programs is necessary to prevent deficiencies and toxicity risks

Nigeria has an alarming prevalence of micronutrient deficiencies that has persisted over decades. National Micronutrient Deficiency Control (MNDC) guidelines describe several interventions to address the issue. This study identified and described currently implemented interventions, assessed coverage and coordination of the interventions, and considered the risk of overdosage and gaps. Methods included reviews of policy and program documents, key informant interviews, market, and pharmacy visits. The study found that an array of MNDC interventions were being implemented, including public health supplementation, mandatory fortification, point-of-use fortification, biofortification, promotion of dietary diversity, voluntary fortification, and ad hoc individual supplement use. Insufficient coordination existed for government, private, and civil society interventions within the health sector and between health and other sectors. Dosages of micronutrients supplied by different interventions were set independently of each other and target populations overlapped. Inadequate implementation of various interventions appeared to reduce the risk of excessive micronutrient intakes, but increased the risk of deficiencies. The risk of excessive intakes will likely increase with improved implementation and scale-up. There is a need to develop effective coordination structures for MNDC in Nigeria that will critically examine the landscape, decide modalities for different interventions, and ensure that both deficiencies and risk of excessive intakes are minimized.

(B2) Periodontal Diseases and Other Bacterial Infections

The workshop addressed the following questions with respect to periodontal diseases and bacterial infections seen in HIV infection: (1) What is linear gingival erythema? Is it prevalent only in HIV disease? A crude Delphi technique was used to ascertain whether LGE existed, but a consensus could not be reached. It was agreed that a diagnosis of LGE should be considered only if the lesion persists after removal of plaque in the initial visit. (2) Do periodontal pockets contribute to viremia in HIV infection? At present, the data are not available to answer this question. (3) Do anti-viral drugs reach the sulcular fluid in significant concentrations? No one at the workshop was aware of data that could answer this question. (4) Does concurrent tuberculosis infection modify the oral manifestations of HIV infection? Though analysis of data from the developing countries does suggest an association between tuberculosis and oral candidiasis, more data and multivariate analysis considering immunosuppression as a confounding factor are necessary, for any conclusions to be derived. (5) What pathogens are involved in periodontal diseases in HIV infection? Periodontal disease may be initiated by conventional periodontal pathogens. But the progression and tissue destruction depend upon the presence of typical and atypical micro-organisms, including viruses, their by-products, increased secretion of potentially destructive inflammatory mediators, and overwhelming host response. (6) How can we diagnose the diseases seen in HIV infection? The answer can be obtained only with data from controlled and blinded studies. It is necessary to design collaborative multi-center longitudinal studies. The results obtained from such large sample sizes can contribute eventually to interpretation of the outcome.

Oral lesions, HIV phenotypes, and management of HIV-related disease: Workshop 4A

The workshop considered 5 questions related to oral lesions, HIV phenotypes, and the management of HIV-related disease, with a focus on evidence and challenges in resource-poor settings. First, are oral lesions unique with respect to geographic location or phenotype? Second, how useful would an oral lesion index be to predict HIV in resource-poor countries with no access to CD4 counts or viral load? Third, what are the latest methods and delivery modes for drugs used to treat oral lesions associated with HIV? Fourth, what is the role of the oral health care worker in rapid diagnostic testing for HIV? Fifth, what ethical and legal issues are to be considered when managing the HIV patient? The consensus of the workshop was the need for additional research in 4 key areas in developing countries: (1) additional investigation of comorbidities associated with HIV infection that may affect oral lesion presentation and distribution, especially in pediatric populations; (2) the development of region-specific algorithms involving HIV oral lesions, indicating cumulative risk of immune suppression and the presence of HIV disease; (3) well-designed clinical trials to test new therapies for oral lesions, new treatments for resistant oral fungal and viral diseases, effectiveness of therapies in children, and new drug delivery systems; and (4) the role of the oral health care worker in rapid diagnostic testing for HIV in various regions of the world.

The role of phosphorylated insulin-like growth factor binding protein-1 in predicting pre-term labour in twin pregnancies

This was a retrospective study, carried out at Yeovil District Hospital, UK, from January 2006 to December 2008, looking at 40 patients with twin pregnancies. The aim was to evaluate the role of phosphorylated insulin-like growth factor binding protein-1 (IGFBP-1) test in the prediction of pre-term delivery in twin pregnancies. All the patients had a transvaginal ultrasound scan for cervical length at 24 weeks, followed by a high vaginal swab for IGFBP-1 at 26 weeks. A total of 95% of women screened negative for the IGFBP-1 test. None of these women delivered before 30 weeks; 7.50% delivered between 30 and 33+6 weeks; 87.5% delivered after 34 weeks. Two women (5.00%) screened positive for phosphorylated insulin-like growth factor binding protein-1; one had a spontaneous pre-term delivery at 30 weeks, while the other patient delivered at 38 weeks. It was concluded that women with twin pregnancies that have negative phosphorylated insulin-like growth factor binding protein-1 have a low risk of delivery before 34 weeks in the absence of other obstetric complications.

Common psychiatric disorders over a lifetime: age of onset, risk and treatment contact in the Nigerian survey of mental health and wellbeing

The study is to estimate prevalence, risk, and contact with services of mental health problems in the Nigerian community. Face-to-face interviews with a representative sample of persons aged 18 years and over (n = 6752) using the World Health Organization's Composite International Diagnostic Interview, Version 3. Lifetime DSM-IV prevalence estimates were 6.5% for anxiety disorders, 3.3% for mood disorders, 3.7% for substance use disorders, and 12.0% for any disorder. The median age of onset (represented by the 50th percentile age of onset) is 25 years for any disorder but ranged from 11 years for anxiety disorder to 42 years for mood disorder. The projected lifetime risks at age 75 years were considerably higher than prevalence estimates. For mood disorders, lifetime risk was 170% higher than the prevalence estimate. Ascertainment bottlenecks seem to account for some low prevalence estimates. In general, only a minority of persons with mental disorders made any treatment contact. The median delay in duration before seeking care ranged between 6 years for mood disorders and 16 years for anxiety disorders. Projected lifetime risks of mood disorders and possible false negatives for some disorders suggest that the societal burden of mental disorders is considerably higher than the prevalence estimates indicate. Nevertheless, even for identified cases, current treatment coverage falls far short of need.

Neonatal bacterial meningitis and dexamethasone adjunctive usage in Nigeria

OBJECTIVE

Neonatal bacterial meningitis is devastating, with attendant high mortality and neurological sequelae. We, therefore, aimed to delineate its current incidence, etiologic, clinical, laboratory spectra, and the effect of steroid therapy on the outcome.

METHODOLOGY

Babies admitted from 1992 to 1995 in the Special Care Baby Unit of the University of Maiduguri Teaching Hospital, Maduguri, Nigeria, with bacterial meningitis were studied prospectively. Neonatal bacterial meningitis was confirmed if the cerebrospinal fluid (CSF) microbiological, chemical, immunological and clinical criteria were satisfied. Detailed neurological follow-up was made.

RESULT

Sixty-nine cases of neonatal bacterial meningitis were encountered, (25 were early-onset, and 44 late-onset); the incidence was 6.5/1000 live births. 22 Positive CSF cultures were grown in early-onset meningitis, and 28 in late-onset disease. Low birth weight showed higher risk of bacterial meningitis and it was significantly more likely in the preterm. X2 = 24.19, p = 0.000001). Gram-negative pathogens were more isolated (28/50, 56%); Escherichia coli (11) being the commonest, while of the Gram-positive pathogens Staphylococcus aureus was most predominant overall (13/50). Concomitant blood culture was positive in 39/50 (78%), inclusive of all 22 "definite" early-onset disease. The CSF WBC was minimally raised (25-30 x 10(6)/L) in 11 (22%) of "definite" neonatal bacterial meningitis. Detection of unusual pathogens was noteworthy: N. meningitidis (2) and H. influenzae (2), contributing 0.6 and 2.2 per 1000 live births and admissions, respectively. Overall mortality was 24.6%. Of the forty survivors, 9 (22.5%) had neurological sequelae: sensorineural hearing deficit (3), hydrocephalus (2), subdural effusion (2), hemiparesis (1), afebrile (recurrent) seizure (1), and there was reduced developmental quotients at 24 months follow-up in 33. Dexamethasone therapy decreased mortality significantly; p = 0.0004.

CONCLUSION

The new information highlighted by this research includes the lack of Group B Streptococcus isolation, the finding of S. pneumoniae, N. meningitidis, H. influenzae and S. aureus as significant pathogens, usefulness of blood cultures in the detection of neonatal bacterial meningitis, increasing resistance of Gram-positive neonatal pathogens to cloxacillin, low CSF WBC, and the finding that the adjunctive use of dexamethasone significantly decreases case fatality and neurological sequelae.

Attitudes toward directly administered antiretroviral therapy (DAART) among HIV-positive inpatients in an inner city public hospital

Directly administered antiretroviral therapy (DAART) is one approach to improve adherence among HIV-positive individuals. DAART has been assessed for confined participants such as prisoners and for patients enrolled in methadone clinics but community-based voluntary DAART programs are not well studied. We examined the attitudes toward DAART among 47 HIV-positive inpatients in an inner city public hospital, a population difficult to engage in conventional self-administered highly active antiretroviral therapy (HAART). This study found that 83% of participants prefer self-administered therapy (SAT) and only 17% elect for DAART. A significant proportion of participants think the approach is intrusive or impractical and few are willing to meet with providers daily. A proportion of our patients, however, struggle with medication non-adherence and fragmented medical care, evident in the high rates of missed clinic appointments, frequent emergency department visits and repeated hospitalizations. These data can inform the development of DAART programs and suggest that considerable effort is needed to 'sell' the idea of DAART to this patient population. It is likely that such patients will greatly benefit from a clinic that can provide intensive counseling, frequent follow-up, home visits and DAART. Patient education regarding the merits of such an approach will be key to success.

Analgesic activity of Peperomia pellucida aerial parts in mice

The methanol extract of Peperomia pellucida aerial parts, given orally at doses ranging from 70 to 210 mg/kg, showed a significant analgesic activity on acetic acid-induced writhing in mice.

Gram negative bacillary meningitis in infants and children in developing countries

Gram negative bacillary meningitis (GNBM) in postneonatal infants and children is two to three times more common in developed compared to developing countries. Other major differences are in the pattern of pathogens (mainly Klebsiella spp and Salmonella spp in developing versus E. coli in developed countries) and associated conditions (diarrhoeal diseases and malnutrition in developing versus neurosurgical and urinary tract abnormalities in developed countries). 12 (11.5%) of 104 cases of bacterial meningitis were due to GNB, including Klebsiella spp seven, E. coli, two and untyped Coliform spp, three; the age range of patients with GNBM was 3-24 months. Among seven completely evaluable patients, six presented after seven days of illness, five convulsed on or before admission, and six had accompanying respiratory or gastro-enteritic illnesses but none was severely malnourished or had associated neurosurgical or urinary tract abnormalities. Three patients died, three were discharged with sequelae and one without sequelae. The only significant difference between patients with GNBM and those with meningitis due to "usual" pathogens was the greater tendency to delayed presentation among the former (6/7 patients with GNBM versus 11/36 "usual" pathogens; p = 0.011); this was also the only striking difference in presentation when compared with patients from developed countries. The need for further studies, preferably multicentred, and for a revision of the traditional combination of gentamicin and ampicillin or chloramphenicol and ampicillin for the treatment of GNBM in developing countries is discussed.

Pattern and antibiotic susceptibility of bacteria in pyogenic meningitis in a children's emergency room population in Maiduguri, Nigeria, 1988-1992

From January 1988 to November 1992, 107 (3.5%) of 3074 postneonatal children admitted to the Children's Emergency Room, University of Maiduguri Teaching Hospital, Nigeria, had sporadic pyogenic meningitis; 66 (61.7%) were aged < or = 12 months. Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae together were responsible for 77.3% (58) of 75 culture-proven cases, 13.4% (10) had Enterobacteriaceae, 5.3% (4) had Staphylococcus aureus and 4% (3) untyped alpha-haemolytic streptococci. Fifty percent of 62 bacteria were resistant to ampicillin, 47.2% of 36 to penicillin and 10.7% of 56 to chloramphenicol; none of 21 bacteria was simultaneously resistant to all three antibiotics. Up until 1992, we have encountered treatment failure with a regimen containing chloramphenicol in only 2 of 53 patients; the 2 patients had coliform meningitis. Non-meningococcal bacteria are an important cause of sporadic pyogenic meningitis in sub-Saharan Nigeria and chloramphenicol is the most appropriate initial drug of choice at the present time for the management of sporadic meningitis.

The numbers and varieties of bacteria carried by filth flies in sanitary and unsanitary city area

Filth flies caught with nets in various localities of varying sanitary conditions in Ibadan city were predominantly Musca domestica and a few Fannia cannicularis. Seven genera of bacteria, some of which were pathogenic to humans, were isolated from the legs, wings, mouthparts and midguts of the flies. Flies were very abundant in areas where unsanitary conditions prevailed and scarce where sanitary conditions were enforced. The total number of bacteria isolated from flies caught in the market places was higher than those isolated from flies caught in any other locality; low numbers of bacteria were isolated from flies caught in areas where hygienic conditions prevailed. Bacillus spp. were the most numerous of the bacteria isolated. The greatest numbers of bacteria were found on the legs. From the house-flies caught on dairy animals were isolated a high number of Escherichia coli. The public health significance of these findings is discussed.
