Prognostic factors and overall survival of breast cancer in Benin: a hospital-based study. BMC Womens Health 2024; 24:295. [PMID: 38762733 PMCID: PMC11102149 DOI: 10.1186/s12905-024-03114-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Accepted: 04/24/2024] [Indexed: 05/20/2024] Open
Abstract
BACKGROUND In Benin, a country in West Africa, breast cancer is the leading cancer in women, both in terms of incidence and mortality. However, evidence on the mortality of breast cancer and its associated factors is lacking in this country. Our aim was to describe and analyze the clinical, histopathological, and prognostic aspects of breast cancer in Benin. METHODS A descriptive and analytical study was carried out at the CNHU-HKM and the CHU-MEL, two major tertiary referral hospitals for breast cancer management located in Cotonou, the capital city of Benin. All breast cancer medical records with histological evidence and immunohistochemistry studies were retrospectively collected between January 1, 2014, and September 30, 2020, in these two tertiary referral hospitals and analyzed in the current study. RESULTS Finally, 319 medical records were included. The mean age at diagnosis was 48.74 years. The tumors were most frequently classified as T4 (47.6%) with lymph node involvement N2 (34.5%), and metastases were clinically noted in 21.9% of cases. Stage was reported in the medical records of 284 patients. Tumors were diagnosed at very late AJCC stages: stage III (47.5%) and stage IV (24.7%). Grades SBR 2 (49.2%) and SBR 3 (32.6%) were the most frequent grades. Triple-negative breast cancer (31.3%) was the most common molecular type. The overall 5-year survival was 48.49%. In multivariable analysis, the poor prognostic factors were lymph node invasion (HR = 2.63; p = 0.026; CI: [1.12, 6.17]), the presence of metastasis (HR = 3.64; p < 0.001); CI: [2.36, 5.62] and the immunohistochemical profile (HR = 1.29; p < 0.001; CI: [1.13, 1.48]). CONCLUSIONS Breast cancer in Beninese is predominant in young adults and is often diagnosed at a late stage. The survival of breast cancer patients in Benin can be improved by enhancing early diagnosis and multidisciplinary management.

Intrageneric cross-reactivity of monospecific rabbit antisera against venoms of mamba (Elapidae: Dendroaspis spp.) snakes. Toxicon X 2024; 21:100183. [PMID: 38274651 PMCID: PMC10808963 DOI: 10.1016/j.toxcx.2023.100183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 12/20/2023] [Accepted: 12/27/2023] [Indexed: 01/27/2024] Open
Abstract
Snakebite envenomation is a neglected tropical disease posing a high toll of mortality and morbidity in sub-Saharan Africa. Polyspecific antivenoms of broad effectiveness and specially designed for this region require a detailed understanding of the immunological features of the mamba snake (Dendroaspis spp.) venoms for the selection of the most appropriate antigen combination to produce antivenoms of wide neutralizing scope. Monospecific antisera were generated in rabbits against the venoms of the four species of mambas. The toxic effects of the immunization scheme in the animals were evaluated, antibody titers were estimated using immunochemical assays, and neutralization of lethal activity was assessed. By the end of the immunization schedule, rabbits showed normal values of the majority of hematological parameters tested. No muscle tissue damage was noticed, and no alterations in most serum chemical parameters were observed. Immunological analyses revealed a variable extent of cross-reactivity of the monospecific antisera against the heterologous venoms. The venoms of D. jamesoni and D. viridis generated the antisera with broader cross-reactivity by immunochemical parameters. The venoms of D. polylepis and D. viridis generated the antisera with better cross-neutralization of lethality, although the neutralizing ability of all antisera was lower than 0.16 mg venom/mL antiserum against either homologous or heterologous venoms. These experimental results must be scaled to large animal models used in antivenom manufacture at industrial level to assess whether these predictions are reproducible.

Childhood stunting is highly clustered in Northern Province of Rwanda: A spatial analysis of a population-based study. Heliyon 2024; 10:e24922. [PMID: 38312557 PMCID: PMC10835355 DOI: 10.1016/j.heliyon.2024.e24922] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 01/03/2024] [Accepted: 01/17/2024] [Indexed: 02/06/2024] Open
Abstract
Background In Northern Province, Rwanda, stunting is common among children aged under 5 years. However, previous studies on spatial analysis of childhood stunting in Rwanda did not assess its randomness and clustering, and none were conducted in Northern Province. We conducted a spatial-pattern analysis of childhood undernutrition to identify stunting clusters and hotspots for targeted interventions in Northern Province. Methods Using a household population-based questionnaire survey of the characteristics and causes of undernutrition in households with biological mothers of children aged 1-36 months, we collected anthropometric measurements of the children and their mothers and captured the coordinates of the households. Descriptive statistics were computed for the sociodemographic characteristics and anthropometric measurements. Spatial patterns of childhood stunting were determined using global and local Moran's I and Getis-Ord Gi* statistics, and the corresponding maps were produced. Results The z-scores of the three anthropometric measurements were normally distributed, but the z-scores of height-for-age were generally lower than those of weight-for-age and weight-for-height, prompting us to focus on height-for-age for the spatial analysis. The estimated incidence of stunting among 601 children aged 1-36 months was 27.1 %. The sample points were interpolated to the administrative level of the sector. The global Moran's I was positive and significant (Moran's I = 0.403, p < 0.001, z-score = 7.813), indicating clustering of childhood stunting across different sectors of Northern Province. The local Moran's I and hotspot analysis based on the Getis-Ord Gi* statistic showed statistically significant hotspots, which were strongest within Musanze district, followed by Gakenke and Gicumbi districts. Conclusion Childhood stunting in Northern Province showed statistically significant hotspots in Musanze, Gakenke, and Gicumbi districts. Factors associated with such clusters and hotspots should be assessed to identify possible geographically targeted interventions.

Climate variability, armed conflicts and child malnutrition in sub-saharan Africa: A spatial analysis in Ethiopia, Kenya and Nigeria. Heliyon 2023; 9:e21672. [PMID: 38027550 PMCID: PMC10656247 DOI: 10.1016/j.heliyon.2023.e21672] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 10/24/2023] [Accepted: 10/25/2023] [Indexed: 12/01/2023] Open
Abstract
Background Sub-Saharan Africa (SSA) has one of the highest prevalence of malnutrition among children under 5 in the world. It is also the region most vulnerable to the adverse effect of climate change, and the one that records the most armed conflicts. The chains of causality suggested in the literature on the relationship between climate change, armed conflict, and malnutrition have rarely been supported by empirical evidence for SSA countries. Methods This study proposes to highlight, under the hypothesis of spatial non-stationarity, the influence of climatic variations and armed conflicts on malnutrition in children under 5 in Ethiopia, Kenya, and Nigeria. To do this, we use spatial analysis on data from Demographic and Health Surveys (DHS), Uppsala Conflict Data Program Georeferenced Event Dataset (UCDP GED), Climate Hazards center InfraRed Precipitation with Station data (CHIRPS) and Moderate Resolution Imaging Spectroradiometer (MODIS). Results The results show that there is a spatial autocorrelation of malnutrition measured by the prevalence of underweight children in the three countries. Also, local geographically weighted analysis shows that armed conflict, temperature and rainfall are positively associated with the prevalence of underweight children in localities of Somali in Ethiopia, Mandera and Turkana of Wajir in Kenya, Borno and Yobe in Nigeria. Conclusion In conclusion, the results of our spatial analysis support the implementation of conflict-sensitive climate change adaptation strategies.

Macrovascular and renal microvascular complications in West Africans with intermediate hyperglycemia living in West Africa and Europe: The RODAM study. Heliyon 2023; 9:e19334. [PMID: 37664733 PMCID: PMC10469941 DOI: 10.1016/j.heliyon.2023.e19334] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 08/14/2023] [Accepted: 08/18/2023] [Indexed: 09/05/2023] Open
Abstract
Background Metabolic conditions, including intermediate hyperglycemia (IH), affect migrants to a greater extent than the populations of origin. Evidence suggests that IH increases the risk of vascular complications, but it is unclear whether the differences in IH between the non-migrant and migrant populations translate to differences in vascular complications between the two populations. We compared the prevalence of macrovascular and renal microvascular complications among West Africans with IH living in West Africa and their migrant compatriots in Europe. Methods Data from the multicenter Research on Obesity and Diabetes among African Migrants(RODAM) study were analyzed. Ghanaians with IH(524 non-migrant and 1439 migrants) were included. Logistic regression analyses were used to determine the associations between migrant status and macrovascular [coronary artery disease(CAD) and peripheral artery disease(PAD)] and renal microvascular[nephropathy] complications with adjustment for age, sex, socioeconomic status, smoking, systolic blood pressure, BMI, total cholesterol, HbA1c, C-reactive protein, and serum uric acid. Findings The prevalence of microvascular/macrovascular complications was higher in non-migrants than in migrants(nephropathy 15.3vs.9.7%; PAD 3.1%vs.1.3%; and CAD 15.8% vs. 5.0%). The differences persisted in the fully adjusted model: nephropathy [odds ratio, 2.12; 95% CI(1.46-3.08); PAD, 4.44(1.87-10.51); CAD 2.35(1.64-3.37)]. Non-migrant females had higher odds of nephropathy[2.14(1.34-3.43)], PAD[7.47(2.38-23.40)] and CAD [2.10(1.34-3.27)] compared to migrant females. Non-migrant males had higher odds of nephropathy[2.54(1.30-4.97)] and CAD[2.85(1.48-5.50)], but not PAD[1.81(0.32-10.29)],than their migrant peers. Interpretation Macrovascular and renal microvascular complications were more prevalent in non-migrants than in migrant West Africans with IH. Further studies are needed to identify factors that increase the risk to aid preventive/treatment strategies.

Biodiesel potential of Cucumeropsis mannii (white melon) seed oil: A neglected and underutilized resource in Nigeria. Heliyon 2023; 9:e16799. [PMID: 37303580 PMCID: PMC10248266 DOI: 10.1016/j.heliyon.2023.e16799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 05/24/2023] [Accepted: 05/29/2023] [Indexed: 06/13/2023] Open
Abstract
A major challenge in the biodiesel industry is the availability of high-quality vegetable oil feedstocks. Thus, there is a continuous search for quality biodiesel feedstock whose production will trigger economic impact on the agricultural sector, minimize land degradation and without significant disruption to the food chain. In this work, we extracted and analysed oil from neglected and underutilized Cucumeropsis mannii seeds for their potential in biodiesel production. The oil content of C. mannii seed was 40.8 ± 0.56%. GC-MS analysis of the oil revealed the presence of 47.0% saturated fatty (predominantly palmitic acid, stearic acid) and 53.0% of unsaturated fatty acids (predominantly oleic, linoleic and erucic acids). The physicochemical properties were determined and values were as follows: iodine value (111.07 ± 0.15 g/100 g), saponification value (192.03 ± 0.37 mg/kg of oil), peroxide value (2.60 ± 0.10 meq/kg), acid value (4.20 ± 0.02 mgKOH/g) free fatty acid (2.51 ± 0.02%), relative density (0.93 ± 0.02), the refractive index at 28 °C (1.46 ± 0.04) and viscosity at 30 °C (3.00 ± 0.10 mm2/s). The fuel properties namely, cloud point, pour point, flash point and caloric value were determined and the values were 3.03 ± 0.11 °C, 1.00 ± 0.10 °C, 279.04 ± 0.99 °C and 31.10 ± 0.11 MJ/kg, respectively. In addition, the protein content of the defatted seed was found to be 47.4 ± 0.61 g/100 g. The defatted protein-rich cakes can be upgraded as a food additive; thus the C. mannii seed oil can serve as biodiesel feedstock without altering the food chain. These characteristics demonstrate the potential of C. mannii oil as a high-quality feedstock for biodiesel production. We envisage that its utilization as biodiesel feedstock will improve the market value of these seeds, thus supporting the economic development of local farmers in rural areas.

Childhood lower respiratory tract infections linked to residential airborne bacterial and fungal microbiota. ENVIRONMENTAL RESEARCH 2023; 231:116063. [PMID: 37156352 DOI: 10.1016/j.envres.2023.116063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/19/2023] [Accepted: 05/04/2023] [Indexed: 05/10/2023]
Abstract
Residential microbial composition likely contributes to the development of lower respiratory tract infections (LRTI) among children, but the association is poorly understood. We aimed to study the relationship between the indoor airborne dust bacterial and fungal microbiota and childhood LRTI in Ibadan, Nigeria. Ninety-eight children under the age of five years hospitalized with LRTI were recruited and matched by age (±3 months), sex, and geographical location to 99 community-based controls without LRTI. Participants' homes were visited and sampled over a 14-day period for airborne house dust using electrostatic dustfall collectors (EDC). In airborne dust samples, the composition of bacterial and fungal communities was characterized by a meta-barcoding approach using amplicons targeting simultaneously the bacterial 16S rRNA gene and the internal-transcribed-spacer (ITS) region-1 of fungi in association with the SILVA and UNITE database respectively. A 100-unit change in house dust bacterial, but not fungal, richness (OR 1.06; 95%CI 1.03-1.10) and a 1-unit change in Shannon diversity (OR 1.92; 95%CI 1.28-3.01) were both independently associated with childhood LRTI after adjusting for other indoor environmental risk factors. Beta-diversity analysis showed that bacterial (PERMANOVA p < 0.001, R2 = 0.036) and fungal (PERMANOVA p < 0.001, R2 = 0.028) community composition differed significantly between homes of cases and controls. Pair-wise differential abundance analysis using both DESEq2 and MaAsLin2 consistently identified the bacterial phyla Deinococcota (Benjamini-Hochberg (BH) adjusted p-value <0.001) and Bacteriodota (BH-adjusted p-value = 0.004) to be negatively associated with LRTI. Within the fungal microbiota, phylum Ascomycota abundance (BH adjusted p-value <0.001) was observed to be directly associated with LRTI, while Basidiomycota abundance (BH adjusted p-value <0.001) was negatively associated with LRTI. Our study suggests that early-life exposure to certain airborne bacterial and fungal communities is associated with LRTI among children under the age of five years.

Source identification with high-temporal resolution data from low-cost sensors using bivariate polar plots in urban areas of Ghana. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2023; 317:120448. [PMID: 36457223 DOI: 10.1016/j.envpol.2022.120448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 10/07/2022] [Accepted: 10/14/2022] [Indexed: 06/17/2023]
Abstract
The emergence of low-cost sensors for atmospheric observations presents a new opportunity for identifying atmospheric emission sources based on high-resolution data reporting. Low-cost sensors have been widely assessed for use in source monitoring and identification of hotspots of key atmospheric species in advanced countries (e.g., for CO, NOx, CO2, SO2, O3, VOCs and PM (PM10, PM2.5 including emerging PM1). In contrast, research in recent years has focused on their utility for real-time monitoring, understanding precision and associated calibration requirements in technologically lagging environments. This leads to limited evidence on the utility of high-resolution data from low-cost sensor networks for air pollution source identification in Ghana and more widely across the African continent. In this paper, we demonstrate the potential of low-cost sensors for emission source apportionment in urban areas of Ghana when used with analytical tools such as sectoral and cluster analysis. With a 14-week dataset from a low-cost sensor deployment study at Cape Coast in the Central Region of Ghana, we aimed to identify sources of particulate matter (PM2.5 and PM10). PM pollution was local (associated with increased PM at wind speeds of ≤2 m s-1). High levels of PM during this study were associated with transport from the NNE. For coarse PM, hourly levels as high as 125 μg m-3 were observed at higher wind speeds (7-8 m s-1) indicating the importance of meteorology in the transport of PM. This study suggests that low-cost sensors could be deployed to (1) augment any existing sparsely distributed air quality monitoring and (2) undertake air quality monitoring for source apportionment studies in areas with no existing air quality observational capability (with appropriate calibration and operation in both cases). The urban landscape monitored in this study is typical of both Ghana and wider areas across Sub-Saharan Africa demonstrating the reproducibility of this study.

Barriers and facilitators of antiretroviral therapy (ART) adherence habit formation in Sub-Saharan Africa: Evidence from a qualitative study in Kampala, Uganda. Soc Sci Med 2023; 317:115567.

Abstract
RATIONALE In 2020, nearly 40 million people lived with HIV/AIDS (PLWHA) worldwide, of whom 70% were receiving antiretroviral therapy (ART). Two-thirds of PLWHA reside in Sub-Saharan Africa (SSA), where rates of viral load suppression are often suboptimal and frequently attributed to low ART adherence. Strong pill-taking habits are often reported as a key strategy among those who successfully maintain medication adherence, yet not enough is known about the barriers and facilitators in SSA to pill-taking in response to the same contextual cue, which is a necessary step in the habit formation process. OBJECTIVE To address this knowledge gap and to inform a subsequent intervention to promote context-dependent repetition, called anchoring, we used a formative qualitative approach to collect in-depth narratives about barriers and facilitators of the anchoring intervention for establishing ART pill-taking habits at the Mildmay Hospital in Kampala, Uganda. METHODS We conducted interviews with 25 randomly selected patients starting ART, 5 expert patients, and 10 providers at Mildmay, and performed a rapid analysis to inform the intervention in a timely manner. RESULTS We found that pill taking in response to the same contextual cue, or anchor, was threatened by stigma and food insecurity and that the COVID-19 pandemic exacerbated these barriers. We also determined that important linguistic changes were needed to the instructional materials and reminder messages in the subsequent intervention to avoid words and phrases with negative connotations for this target population. CONCLUSIONS Several important barriers and facilitators to context-dependent pill taking in Uganda were identified through our formative research that helped to inform important revisions to our subsequent intervention. These findings underscore the importance of understanding local barriers and facilitators when designing and planning interventions, particularly when implementing theory-based intervention approaches that have yet to be tested in a new setting.

Abstract
Introduction Pilot/feasibility studies represent a fundamental phase of the research process and play a vital role in the preliminary planning of a full size HIV clinical trial. Published HIV clinical trial protocols were reviewed to establish the extent to which the proposed HIV clinical trials are informed by a prior pilot/feasibility study. Methods The JBI methodology for scoping reviews was followed. Six databases were systematically searched to identify articles for inclusion. Results Thirty two (32) published HIV study protocols were included. Articles were in the English language and were published in the past 10 years (2011-2020). The review results showed that the majority of HIV-related clinical trials in sub-Saharan Africa were not informed by pilot/feasibility studies. The results further indicated that the number of HIV clinical trials informed by a pilot/feasibility study have been on the increase in the 8 years' period since 2012, a trend that indicates positive uptake of pilot studies in HIV related studies. A few select countries (South Africa, Uganda, Zimbabwe, Malawi and Kenya) comprised more than 70% of all clinical trials that were informed by a pilot/feasibility study, conducted in sub Saharan Africa. Conclusions Although there is an increasing interest among researchers to integrate pilot/feasibility studies in HIV related research, limited countries in sub-Saharan Africa appear to have embraced this trend. Strategies that can motivate researchers to engage in a culture of incorporating pilot/feasibility studies in HIV related research should be implemented.

Abstract
INTRODUCTION Chronic diseases are increasing but underdiagnosed in low-income and middle-income countries (LMICs), where injury mortality is already disproportionately high. We estimated prevalence of known chronic disease comorbidities and their association with outcomes among injured patients in Cameroon. MATERIALS AND METHODS Injured patients aged ≥15 y presenting to four Cameroonian hospitals between October 2017 and January 2020 were included. Our explanatory variable was known chronic disease; prevalence was age-standardized. Outcomes were overall in-hospital mortality and admission or transfer from the emergency department (ED). Associations between known chronic disease and outcomes were evaluated using logistic regression adjusted for age, gender, estimated injury severity score (eISS), hospital, and household socioeconomic status. Unadjusted eISS-stratified and age-stratified outcomes were also compared via chi-squared tests. RESULTS Of 7509 injured patients, 370 (4.9%) reported at least one known chronic disease; age-standardized prevalence was 8.4% (95% confidence interval [CI] 7.5%-9.2%). Patients with known chronic disease had higher mortality (4.6% versus 1.5%, adjusted odds ratio [aOR]: 2.61 [95% CI: 1.25-5.47], P = 0.011) and were more likely to be admitted or transferred from the ED (38.7% versus 19.8%, aOR: 1.40 [95% CI: 1.02-1.92], P = 0.038) compared to those without known comorbidities. Crude differences in mortality (11.3% versus 3.3%, P = 0.002) and hospital admission or transfer (63.8% versus 46.6%, P = 0.011) were most notable for patients with eISS 16-24. CONCLUSIONS Despite underdiagnosis among Cameroonians, we demonstrated worse injury outcomes among those with known chronic diseases. Integrating chronic disease screening with injury care may help address underdiagnosis in Cameroon. Future work should assess whether chronic disease prevention in LMICs could improve injury outcomes.

Abstract
The RTS,S malaria vaccine was recently recommended for use among children at risk in malaria endemic regions. Although significant efforts have been made to minimise malaria cases, the results of these innovations have not been totally satisfactory due to specific limitations. However, this revolutionary vaccine has a great tendency to put an end to malaria. Being the first vaccine against malaria, this commentary examines its journey from the idealisation and conception to the recommendation by the World Health Organization. The commentary also examines some of the challenges that might affect the execution of the vaccination programme in sub-Saharan Africa and other malaria endemic regions and suggest recommendations to overcome the possible them.

Abstract
Hazardous drinking by persons living with HIV (PLHIV) is a well-established determinant of sub-optimal HIV care and treatment outcomes. Despite this, to date, few interventions have sought to reduce hazardous drinking among PLHIV in sub-Saharan Africa (SSA). We describe an iterative cultural adaptation of an evidence-based multi-session alcohol reduction intervention for PLHIV in southwestern Uganda. The adaptation process included identifying core, theoretically informed, intervention elements, and conducting focus group discussions and cognitive interviews with community members, HIV clinic staff and patients to modify key intervention characteristics for cultural relevance and saliency. Adaptation of evidence-based alcohol reduction interventions can be strengthened by the inclusion of the target population and key stakeholders in shaping the content, while retaining fidelity to core intervention elements.

Going viral - capacity strengthening in the context of pandemic(s). Best Pract Res Clin Obstet Gynaecol 2021; 80:39-48. [PMID: 34866002 PMCID: PMC8590612 DOI: 10.1016/j.bpobgyn.2021.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 10/19/2021] [Accepted: 10/22/2021] [Indexed: 11/22/2022]
Abstract
Strengthening the capacity of midwives and nurses in low- and middle-income countries to lead research is an urgent priority in embedding and sustaining evidence-based practice and better outcomes for women and newborns during childbearing. International and local travel restrictions, and physical distancing resulting from the COVID-19 pandemic have compromised the delivery of many existing programmes and challenged international partnerships working in maternal and newborn health to adapt rapidly. In this paper, we share the experiences of a midwife-led research partnership between Kenya, Malawi, Tanzania, Uganda, the UK, Zambia and Zimbabwe in sustaining and enhancing capacity strengthening activities remotely in this period. Whilst considerable challenges arose, and not all were overcome, collectively, we gained new insights and important learning which have shifted perspectives and will impact future design and delivery of learning programmes.

COVID-19 and handwashing: Implications for water use in Sub-Saharan Africa. WATER RESOURCES AND ECONOMICS 2021; 36:100189. [PMID: 34745865 PMCID: PMC8563594 DOI: 10.1016/j.wre.2021.100189] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 09/27/2021] [Accepted: 10/28/2021] [Indexed: 05/21/2023]
Abstract
Because the main modes of transmission of the COVID-19 virus are respiration and contact, WHO recommends frequent washing of hands with soap under running water for at least 20 s. This article investigates how the level of concern about COVID-19 affects the likelihood of washing hands frequently in sub-Saharan Africa. We discuss the implication of the findings for water-scarce environment. The study makes use of a unique survey dataset from 12 sub-Saharan African countries collected in April 2020 (first round) and May 2020 (second round) and employs an extended ordered probit model with endogenous covariate. The results show that the level of concern about the spread of the virus increases the likelihood of washing hands with soap under running water for a minimum of 20 s at least five times a day. The increase in the probability of handwashing due to concern about COVID-19, ranges from 3% for Benin to 6.3% for South Africa. The results also show heterogeneous effects across gender- and age-groups, locality and various water sources. However, in Africa, the sustainability of the handwashing protocol could be threatened by the severe water scarcity that exists in the region. To sustain frequent handwashing, sub-Saharan Africa needs an effective strategy for water management and supply.

Country-level assessment of agrifood waste and enabling environment for sustainable utilisation for bioenergy in Nigeria. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2021; 294:112929. [PMID: 34139644 DOI: 10.1016/j.jenvman.2021.112929] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Revised: 05/04/2021] [Accepted: 05/08/2021] [Indexed: 06/12/2023]
Abstract
It is essential to plug inefficiencies due to agrifood losses and wastes, which pose a significant threat to the sustainable supply of nutritional agrifood commodities/products. Country-specific evaluations of the extent of agrifood losses/wastes, including the pathways and impacts on net agrifood production, are crucial to inform interventions, research, policies and investments. This kind of knowledge is scarce in sub-Saharan Africa (SSA) countries, many of which are food insecure. This paper presents an estimation of and the bioenergy potential for agrifood loss and waste (AFW) - the edible and inedible residual biogenic fractions of crops and animal commodities/products - in Nigeria. Our findings reveal that Nigeria generates 183.3 ± 8.9MT of AFW per annum. About 27% of the average annual total domestic supply of edible agrifood commodities/products is lost before reaching markets/consumers. The intrinsic bioenergy potential of the inedible AFW fraction generated annually in Nigeria is estimated to be 1,816.8 ± 117.3PJ; this is sufficient to meet 2030's bioenergy targets and replace a third of its total (grid, off-grid and self-generation) supply targets. However, Nigeria lacks regulatory, policy and institutional frameworks specific to AFW management. This study recommends a sustainable approach to managing AFW, addressing the interlinked challenges of bioenergy production, public health and environmental sustainability. Besides addressing knowledge gaps in the Nigerian agrifood sector, the information generated in this study is well-timed to inform decision-making and policy formulation on decentralised AFW-based bioenergy interventions to achieve energy supply targets in the country by 2030 and beyond. This study is also strategic to guide future research/interventions that align with AFW utilisation/clean energy generation in SSA.

Food Should not be Forgotten: Impacts of Combined Cash Transfer Receipt and Food Security on Child Education and Cognition in South Africa and Malawi. AIDS Behav 2021; 25:2886-2897.

Abstract
Social protection can take many forms. Both cash transfers and food security may have important contributions to child cognitive development. This study examines the potential impact of combinations of cash transfers and food security status on child cognitive development and educational outcomes. Cross-sectional data for 796 HIV-affected children in the Child Community Care study were utilised for this analysis. Children and caregivers completed interview schedules comprised of standardised items on socio-demographics, household data, cash grant receipt and food security status, school achievement, and cognition. A series of logistic and linear regression models and marginal effects analyses were undertaken to explore the impacts of differing levels of social protection (none; either cash grant receipt or food secure status or, both in combination) on child educational and cognitive outcomes. Although all children lived in poverty-stricken households, 20% (157/796) of children did not live in a household in receipt of a cash grant and did not report food security; 32.4% (258/796) reported either component of social protection and, 47.9% (381/796) received both measures of social protection in combination. Compared to no social protection, being in receipt of either component of social protection was found to be significantly associated with being in the correct class for age, higher scores of non-verbal cognition, and higher working memory scores. Receiving both social protection measures in combination was found to be significantly associated with reduced educational risk scores, improved odds of being in the correct class for age, regular school attendance, missing less than a week of school in the previous two weeks, higher scores on measures of nonverbal cognition, higher working memory scores, and learning new things more easily. Educational and cognitive outcomes for children can be bolstered by social protection measures (cash grant receipt or food security). Benefits are enhanced when social protection is received in combination. Such findings support the notion of synergistic social protection responses for children living in environments impacted by high levels of HIV burden and deprivation.

Abstract
We investigated a novel community-based HIV testing and counseling (HTC) strategy by recruiting men from bars in northern Tanzania in order to identify new HIV infections. All bars in the town of Boma Ng'ombe were identified and male patrons were systematically invited to participate in a health study. HIV testing was offered to all enrolled participants. Outputs included HIV test yield, cost per diagnosis, and comparison of our observed test yield to that among male patients contemporaneously tested at five local facility-based HTC. We enrolled 366 participants and identified 17 new infections - providing a test yield of 5.3% (95% Confidence interval [CI] 3.3-8.4). The test yield among men contemporaneously tested at five local HTC centers was 2.1% (95% CI 1.6-2.8). The cost-per-diagnosis was $634. Our results suggest that recruiting male bar patrons for HIV testing is efficient for identifying new HIV infections. The scalability of this intervention warrants further evaluation.

Implementation of HPV-based screening in Burkina Faso: lessons learned from the PARACAO hybrid-effectiveness study. BMC WOMENS HEALTH 2021; 21:251. [PMID: 34162367 PMCID: PMC8220722 DOI: 10.1186/s12905-021-01392-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Accepted: 06/11/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Cervical cancer screening in sub-Saharan countries relies on primary visual inspection with acetic acid (VIA). Primary human papillomavirus (HPV)-based screening is considered a promising alternative. However, the implementation and real-life effectiveness of this strategy at the primary-care level in limited-resource contexts remain under explored. In Ouagadougou, Burkina Faso, free HPV-based screening was implemented in 2019 in two primary healthcare centers. We carried out a process and effectiveness evaluation of this intervention. METHODS Effectiveness outcomes and implementation indicators were assessed through a cohort study of screened women, observations in participating centers, individual interviews with women and healthcare providers and monitoring reports. Effectiveness outcomes were screening completeness and women's satisfaction. Logistic regression models and concurrent qualitative analysis explored how implementation variability, acceptability by women and the context affected effectiveness outcomes. RESULTS After a 3-month implementation period, of the 350 women included in the cohort, 94% completed the screening, although only 26% had their screening completed in a single visit as planned in the protocol. The proportion of highly satisfied women was higher after result disclosure (95%) than after sampling (65%). A good understanding of the screening results and recommendations increased screening completeness and women's satisfaction, while time to result disclosure decreased satisfaction. Adaptations were made to fit healthcare workers' workload. CONCLUSION Free HPV-based screening was successfully integrated within primary care in Ouagadougou, Burkina Faso, leading to a high level of screening completeness despite the frequent use of multiple visits. Future implementation in primary healthcare centers needs to improve counseling and reduce wait times at the various steps of the screening sequence.

Effect of operational strategies on microbial water quality in small scale intermittent water supply systems: The case of Moamba, Mozambique. Int J Hyg Environ Health 2021; 236:113794.

Abstract
Intermittent drinking water supply affects the health of over 300 million people globally. In Mozambique, it is largely practiced in cities and small towns. This results in frequent microbial contamination of the supplied drinking water posing a health risk to consumers. In Moamba, a small town in Southern Mozambique with 2,500 water connections, the impact of changes in operational strategies, namely increased chlorine dosage, increased supply duration and first-flush, on the microbial water quality was studied to determine best practices. To that aim, water quality monitoring was enhanced to provide sufficient data on the microbial contamination from 452 samples under the different strategies. The water at the outlet of the water treatment plant during all strategies was free of E. coli complying to the national standards. However, E. coli could be detected at household level. By increasing the chlorine dosage, the number of samples that showed E. coli absence increased at the two sampling locations in the distribution network: in Cimento from 72% to 83% and in Matadouro from 52% to 86%. Modifying the number and duration of supply cycles showed a different impact on the water quality at both locations in the distribution network. A positive effect was shown in Cimento, where the mean concentrations decreased slightly from 0.54 to 0.23 CFU/100 mL and 16.7 to 7.3 CFU/100 mL for E. coli and total coliforms respectively. The percentage of samples positive for bacteria was, however, similar. In contrast, a negative effect was shown in Matadouro where the percentage of positive samples increased and the mean bacterial concentrations increased slightly: E. coli from 0.9 to 1.5 CFU/100 mL and total coliforms 17.6 to 23.0 CFU/100 mL. Enhanced water quality monitoring improved operational strategies safeguarding the microbial water quality. The E. coli contamination of the drinking water at household level could point at recontamination in the distribution or unsafe hygienic practices at household level. Presence of faecal contamination at household level indicates potential presence of pathogens posing a health risk to consumers. Increasing chlorine dosage ensured good microbiological drinking water quality but changing the number of supply cycles had no such effect.

Economic empowerment and intimate partner violence: a secondary data analysis of the cross-sectional Demographic Health Surveys in Sub-Saharan Africa. BMC WOMENS HEALTH 2021; 21:241. [PMID: 34118922 PMCID: PMC8199805 DOI: 10.1186/s12905-021-01363-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 05/17/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND Intimate partner violence (IPV) has been recognized as a defining human rights, development and public health issue of our time. Economic empowerment is one of the most promising interventions to reduce IPV in sub-Saharan Africa, yet the evidence around economic factors that are key to ensure a reduction in IPV are still mixed. Furthermore, there is a lack of clarity on what kinds of economic empowerment works for which population group. This paper seeks a more nuanced understanding, by investigating whether the associations between indicators of economic empowerment and physical and/or sexual IPV are similar between the general population of women and among urban versus rural and young, or middle aged women versus older women. METHODS Using couples data from 25 DHS surveys across 15 countries (n = 70,993 women and men aged 15 and above at time of survey), we analyse how household wealth, men's and women's education and employment status, decision making on women's income, differences in education and employment of women and their partners and women's cash income are associated with physical and/or sexual IPV. We also provide sub-analyses for both urban and rural areas and for women aged, 15 to 24 25 to 34 and 35 to 49. RESULTS Across all surveys, 20% of women reported physical and/or sexual IPV in the last 12 months. On the one hand, our findings reinforced certain well-established patterns between women's economic empowerment and IPV, with women's and men's higher levels of education and increased household wealth associated with a decrease in IPV, and women's employment, especially if only the woman worked, and women earning more than her partner associated with an increase in IPV. Most patterns did not differ across urban and rural settings and age groups, but notable differences emerged regarding household wealth, women's and men's employment in the last 12 months and relative employment and education. CONCLUSIONS Factors relating to women's economic empowerment are vital in understanding and addressing IPV. Our analysis indicate however that future interventions need to consider the differing needs of urban and rural areas as well as be targeted to different age groups.

Abstract
Rural off-grid renewable energy solutions often fail due to uncertainties in household energy demand, insufficient community engagement, inappropriate financial models and policy inconsistency. Social shaping of technology (SST) of household appliances provides a critical lens of understanding the involved socio-technical drivers behind these constraints. This study employs an SST lens to investigate appliance uptake drivers in 14,580 households in Rwanda, such that these drivers can aid in policy design for green growth at the grassroots level. The methodology includes an epistemological review of non-income drivers of appliance uptake. Empirical analysis using a binary logistic regression, based on which disruptive innovation pathways were derived for fostering green growth. Results showed that appliance uptake was highly gendered and skewed across the Ubudehe (social welfare) categories. ICT-devices like mobile phones and radios had a higher likelihood of ownership than welfare appliances like refrigerator and laundry machines. Fans and cookers also demonstrated a greater probability of ownership. Disruptive innovation pathways were derived from leveraging the ICT-driven wave of appliance ownership, creation of service sectors through off-grid renewable solutions and promoting cleaner fuel-switching of cooking energy at the household level. Further policy implications were drawn to support the creation of consumption identities for green growth.

Abstract
In parts of sub-Saharan Africa, where HIV prevalence is high, HIV is a leading cause of death among youths. Orphaned and separated youths are an especially vulnerable group, yet we know little about what influences their testing behavior. We conducted multiple logistical regression to examine theory-based predictors of past-year HIV testing among 423 orphaned and separated youths in Ethiopia, Kenya and Tanzania. We also conducted moderation, assessing whether predictors varied by sex. Over one-third of our sample reported past-year HIV testing. Those with greater perceived social support and those who reported sexual HIV risk behavior were more likely to report past-year testing. Furthermore, boys who reported ever previously testing for HIV were more likely, a year later, to report past-year HIV testing. In conclusion, our findings have important implications for intervention development, including the potential for enhanced perceived social support to positively influence HIV testing among orphaned and separated youths.

Abstract
Human papillomavirus (HPV)-related cervical lesions in first-generation immigrant African women in France should reflect the epidemiology of high-risk (HR)-human papillomavirus (HPV) infection in sub-Saharan Africa. First-generation immigrant African women attending the Centre Hospitalier Régional of Orléans, France, were prospectively subjected to endocervical swabs for HPV DNA PCR and Pap smear. Fifty women (mean age, 41.7 years) living in France (mean stay, 10.7 years) were enrolled, including 26.0% of HIV-negative women from general population and 74.0% of women with known HIV infection. Cervical HPV prevalence was 68.0%, with 56.0% of HR-HPV. HR-HPV -68 and -58 were the predominant genotypes (20.0% and 14.0%, respectively). HR-HPV-16 and HR-HPV-18 were infrequently detected. HIV-infected women showed a trend to be more frequently infected by HPV than HIV-negative women (70.3% versus 61.5%). Most women (84.0%) showed normal cytology, while the remaining (16.0%) exhibited cervical abnormalities and were frequently HIV-infected (87.5%). These observations highlight the unsuspected high burden of cervical HR-HPV infections mostly associated with atypical genotypes, HIV infection and cervical abnormalities in first-generation immigrant African women living in France.

Abstract
The adverse impact of exposure to war-related traumatic events on mental health is well documented. Few studies, however, have focused on the impact of exposure to war-related traumatic events on HIV sexual risk behavior in post-conflict countries such as Liberia. We investigated whether exposure to war-related traumatic events was linked to HIV sexual risk behavior, and identified potential mediators of this relationship, including stressful life events, problematic alcohol use, and intimate partner violence (IPV) among women and men in Liberia. Data were collected from a sample of 395 participants in Monrovia, Liberia. Results from the serial multiple mediator model did not support direct or indirect effects between war-related traumatic events and HIV sexual risk behavior among women. For men, we found both direct and indirect effects between war-related traumatic events and HIV sexual risk behavior. Findings from this research highlight the need for trauma-informed HIV prevention strategies in Liberia.

Abstract
As in other sub-Saharan countries, the burden of depression is high among people living with HIV in Malawi. However, the association between depression at ART initiation and two critical outcomes-retention in HIV care and viral suppression-is not well understood. Prior to the launch of an integrated depression treatment program, adult patients were screened for depression at ART initiation at two clinics in Lilongwe, Malawi. We compared retention in HIV care and viral suppression at 6 months between patients with and without depression at ART initiation using tabular comparison and regression models. The prevalence of depression among this population of adults newly initiating ART was 27%. Those with depression had similar HIV care outcomes at 6 months to those without depression. Retention metrics were generally poor for those with and without depression. However, among those completing viral load testing, nearly all achieved viral suppression. Depression at ART initiation was not associated with either retention or viral suppression. Further investigation of the relationship between depression and HIV is needed to understand the ways depression impacts the different aspects of HIV care engagement.

Abstract
Intimate partner violence has been associated with numerous consequences for women, including pregnancy termination. This study aimed to examine the association between intimate partner violence and pregnancy termination among adolescent girls and young women in 25 sub-Saharan African countries. Data for this study was obtained from the demographic and health surveys of 25 countries in sub-Saharan Africa, published between 2010 and 2019. A total of 60,563 adolescent girls and young women were included in this study. Binary logistic regression models were used in analyzing the data and the results were presented as crude odds ratios (CORs) and adjusted odds ratios (AORs) at 95% confidence interval (CI). The prevalence of intimate partner violence and pregnancy termination among adolescent girls and young women in the 25 countries in sub-Saharan Africa were 19% and 10.1% respectively. In all these countries, the odds of pregnancy termination was higher among adolescent girls and young women who had ever experienced intimate partner violence, compared to those who had never experienced intimate partner violence [COR = 1.60, 95% CI = 1.51-1.71], and this persisted after controlling for confounders [AOR = 1.58, 95% CI = 1.48-1.68]. However, across countries, intimate partner violence had significant association with pregnancy termination among adolescent girls and young women in Angola, Chad, Congo DR and Gabon (Central Africa); Benin, Burkina Faso, Cote D'lvoire, Gambia and Mali (West Africa); Comoros, Rwanda and Uganda (East Africa); and Malawi and Zambia (Southern Africa). The findings imply that reducing pregnancy termination among adolescent girls and young women in sub-Saharan Africa depends on the elimination of intimate partner violence. Thus, policies and programmes aimed at reducing pregnancy termination among adolescent girls and young women in sub-Saharan Africa, should pay particular attention to those who have history of intimate partner violence.

Abstract
Mounting evidence suggests that youth in sub-Saharan Africa (SSA) find themselves increasingly drawn to gambling related activities; an issue, that if left unchecked, can lead to adverse consequences including financial difficulties, crime and mental health problems. To better understand the psychosocial mechanisms underlying problem gambling, there is a pressing need to conduct more research on gambling related disorders amongst this vulnerable stratum of society. Against this background, the present review explores gambling patterns, attitudes and behaviors among youth in SSA-in a manner aligning with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We systematically searched 8 databases including PubMed, Science Direct, Scopus, ProQuest, Wiley Online, Google Scholar, PsycINFO and PsycARTICLES for published research articles up until July 2019. A total of 1624 articles were screened, of which, only 13 studies met inclusion criteria. All of these studies were cross-sectional in nature and the quality of each study was evaluated using the Newcastle-Ottawa Scale. Studies varied considerably ranging from neuropsychological and personality trait assessment to application of item response theory. Due to this study heterogeneity we could not conduct a meta-analysis. The results presented here suggest that the existing body of evidence pertaining to patterns of gambling-related harm among youth in SSA is weak. This study highlights the need for additional good quality studies focusing on gambling related behaviors and prevalence levels among the continent's youth. Additionally, the findings reported herein emphasise the need for implementing social policies alongside effective public health interventions to tackle gambling addiction.

[PMID: 33478542 PMCID: PMC7819232 DOI: 10.1186/s12978-021-01072-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Accepted: 01/05/2021] [Indexed: 11/21/2022] Open
Abstract
Background Most maternal deaths occur during the intrapartum and peripartum periods in sub-Saharan Africa, emphasizing the importance of timely access to quality health service for childbirth and postpartum care. Increasing facility births and provision of postpartum care has been the focus of numerous interventions globally, including in sub-Saharan Africa. The objective of this scoping review is to synthetize the characteristics and effectiveness of interventions to increase facility births or provision of postpartum care in sub-Saharan Africa. Methods We searched for systematic reviews, scoping reviews, qualitative studies and quantitative studies using experimental, quasi experimental, or observational designs, which reported on interventions for increasing facility birth or provision of postpartum care in sub-Saharan Africa. These studies were published in English or French. The search comprised six scientific literature databases (Pubmed, CAIRN, la Banque de Données en Santé Publique, the Cochrane Library). We also used Google Scholar and snowball or citation tracking. Results Strategies identified in the literature as increasing facility births in the sub-Saharan African context include community awareness raising, health expenses reduction (transportation or user fee), non-monetary incentive programs (baby kits), or a combination of these with improvement of care quality (patient’s privacy, waiting time, training of provider), and or follow-up of pregnant women to use health facility for birth. Strategies that were found to increase provision of postpartum care include improvement of care quality, community-level identification and referrals of postpartum problems and transport voucher program. Conclusions To accelerate achievements in facility birth and provision of postpartum care in sub-Saharan Africa, we recommend strategies that can be implemented sustainably or produce sustainable change. How to sustainably motivate community actors in health interventions may be particularly important in this respect. Furthermore, we recommend that more intervention studies are implemented in West and Central Africa, and focused more on postpartum. Plain English summary In in sub-Saharan Africa, many women die when giving or few days after birth. This happens because they do not have access to good health services in a timely manner during labor and after giving birth. Worldwide, many interventions have been implemented to Increase the number of women giving birth in a health facility or receiving care from health professional after giving birth. The objective of this study is to synthetize the characteristics and effectiveness of interventions that have been implemented in sub-Saharan Africa, aiming to increase the number of women giving birth in a health facility or receiving care from health professional after birth. To proceed with this synthesis, we did a review of studies that have reported on such interventions in sub-Saharan Africa. These studies were published in English or French. The interventions identified to increase the number of women giving birth in a health facility include community awareness raising, reduction of health expenses (transportation or user fee), non-monetary incentive programs (baby kits), or a combination of these with improvement of care quality (patient’s privacy, waiting time, training of provider), and or follow-up of pregnant women to use health facility for birth. Interventions implemented to increase the number women receiving care from a health professional after birth include improvement of care quality, transport voucher program and community-level identification and referrals to the health center of mothers’ health problems. In sub-Saharan Africa, to accelerate increase in the number of women giving birth in a health facility and receiving care from a health professional after, we recommend interventions that can be implemented sustainably or produce sustainable change. How to sustainably motivate community actors in health interventions may be particularly important in this respect. Furthermore, we recommend the conduct in West and Central Africa, of more studies targeting interventions to increase the number of women giving birth in a health facility and or receiving care from a health professional after birth.

Investigating the Relationship between Food Insecurity and Fertility Preferences in Tanzania. Matern Child Health J 2020; 25:302-310. [PMID: 33185825 DOI: 10.1007/s10995-020-03022-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/04/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVE We analyze fertility preferences among women at risk of pregnancy with children ages five or younger as a function of two food security metrics: perceptions of household hunger and child stunting (height for age z scores ≤ -2.0) in order to convey a robust picture of food insecurity. METHODS We use data from the 2016 Tanzania Demographic and Health Surveys to analyze this research question. Multinomial generalized logit models with cluster-adjusted standard errors are used to determine the association between different dimensions of food insecurity and individual-level fertility preferences. RESULTS On average, women who experience household hunger are 19% less likely to want more children compared to women who do not experience household hunger (AOR: 0.81, p = 0.02) when controlling for education, residence, maternal age, number of living children, and survey month. Adjusting for the same covariates, having at least one child ≤ 5 years old who is stunted is associated with 13% reduced odds of wanting more children compared to having no children stunted (AOR: 0.87, p = 0.06). CONCLUSIONS FOR PRACTICE In the context of a divided literature base, this research aligns with the previous work identifying a preference among women to delay or avoid pregnancy during times of food insecurity. The similarity in magnitude and direction of the association between food insecurity and fertility preferences across the two measures of food insecurity suggest a potential association between lived or perceived resource insecurity and fertility aspirations. Further research is needed in order to establish a mechanism through which food insecurity affects fertility preferences. SIGNIFICANCE STATEMENT Individual fertility preferences are sensitive to dynamic multi-level factors in a woman's life. While qualitative research has explored the effect that food insecurity and associated resource constraints have on fertility preferences, results are conflicting. Here, we quantitatively examine how individual woman's fertility preferences associate with two measures of food insecurity and qualitatively compare the associations across food insecurity measures. We establish that two food insecurity measures- household hunger and child stunting- capture similar populations and have similar associations with fertility preferences. This is a critical step forward in understanding the dynamic relationship between resource availability, child well-being, and fertility preferences.

The Economic Costs of COVID-19 in Sub-Saharan Africa: Insights from a Simulation Exercise for Ghana. THE EUROPEAN JOURNAL OF DEVELOPMENT RESEARCH 2020; 32:1353-1378. [PMID: 33144762 PMCID: PMC7596625 DOI: 10.1057/s41287-020-00332-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 10/21/2020] [Indexed: 05/24/2023]
Abstract
Globally, countries have resorted to social distancing, travel restrictions and economic lockdowns to reduce transmission of COVID-19. The socioeconomic costs of these blunt measures are expected to be high, especially in sub-Saharan Africa where many live hand-to-mouth and lack social safety nets. Social Accounting Matrix multiplier model results show that Ghana's urban lockdown, although in force for only three weeks in April 2020, has likely caused GDP to fall by 27.9% during that period, while an additional 3.8 million Ghanaians temporarily became poor. Compared to the government's revised GDP growth rate of 1.5% for 2020, the model predicts a contraction of 0.6 to 6.3% for 2020, depending on the speed of the recovery. The US$200 million budgeted for Ghana's Coronavirus Alleviation Program will close only a small part of the estimated US$ 2.3 billion GDP gap between the fast recovery scenario and government's revised GDP trajectory.

Autonomy in HIV testing: a call for a rethink of personal autonomy in the HIV response in sub-Saharan Africa. MEDICINE, HEALTH CARE, AND PHILOSOPHY 2020; 23:519-536. [PMID: 32535874 PMCID: PMC7292930 DOI: 10.1007/s11019-020-09959-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 06/11/2023]
Abstract
The author reviews various conceptions of autonomy to show that humans are actually not autonomous, strictly speaking. He argues for a need to rethink the personal autonomy approaches to HIV testing in sub-Saharan Africa (SSA) countries. HIV/AIDS has remained a leading cause of disease burden in SSA. It is important to bring this disease burden under control, especially given the availability of current effective antiretroviral regimens in low- and middle-income countries. In most SSA countries the ethic or value of personal autonomy or self-determination is promoted as primary in HIV testing decision-making. SSA policymakers have an ontological and moral duty to adopt HIV testing policies that reflect human and medical realities, relationships, local contexts, and respect human rights for both individuals and others who are affected by HIV in society. Without rethinking the value of autonomy in HIV testing decision-making, the article cautions that attainment of the Sustainable Development Goal (SDG) 3 and the UNAIDS fast-track strategy that explicitly call to end the epidemic by 2030 will not be feasible for SSA.

Mental health response to the COVID-19 pandemic in Kenya: a review. Int J Ment Health Syst 2020; 14:68. [PMID: 32821271 PMCID: PMC7433266 DOI: 10.1186/s13033-020-00400-8] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 08/11/2020] [Indexed: 11/10/2022] Open
Abstract
Background The COVID-19 pandemic has exerted considerable impact on public mental health globally. With the pandemic rapidly rising in sub-Saharan Africa including Kenya, there is need to provide evidence to guide the mental health response in the region. Objectives The objective of this review is (1) to describe the mental health response to the COVID-19 pandemic in Kenya, guided by the Mental Health Preparedness and Action Framework (2) to offer context specific recommendations for improvement of the mental health response in Kenya. Such information could be useful in decision-making in Kenya as well as in the greater sub-Saharan Africa region. Methods This narrative review is based on information obtained from official government documents released from 13th March 2020, the beginning of the pandemic in Kenya, up to 31st July 2020. Discussion The COVID-19 response in Kenya has no formal mental health response plan. There is an unmet need for psychological first aid in the community. While guidelines for the management of mental health conditions during the COVID-19 pandemic have been prepared, implementation remains a major challenge due to a poorly resourced mental health system. There is no mental health surveillance system in place limiting ability to design evidence-based interventions. Conclusion We propose four key strategies for strengthening the mental health response in order to mitigate the harmful impact of COVID-19 on public mental health in Kenya: (1) preparation of a formal mental health response plan specific to the COVID-19 pandemic with allocation of funding for the response (2) training of community health workers and community health volunteers on psychological first aid to enable access to support for those in need during the pandemic (3) scaling up of mobile health to increase access to care (4) conducting systematic and continuous text message surveys on the mental health impact of the COVID-19 pandemic in order to inform decision-making.

Patient experiences in managing non-communicable diseases in Namibia. Res Social Adm Pharm 2020; 16:1550-1557. [PMID: 32919919 DOI: 10.1016/j.sapharm.2020.08.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2020] [Revised: 07/30/2020] [Accepted: 08/06/2020] [Indexed: 12/23/2022]
Abstract
INTRODUCTION The prevalence of non-communicable diseases (NCDs) is rising in Namibia, and with it, the need for pharmacists to empower patients. This research aims to 1) identify patient-reported barriers and facilitators to managing chronic NCDs for Namibians, and 2) characterize common patient-reported medication and health-related needs of Namibians with chronic NCDs. METHODS This qualitative study used semi-structured interviews to elicit participant perspectives regarding NCDs. The study used the conceptual frameworks of the Health Belief Model, the Theory of Planned Behavior, and the Explanatory Models of Illness to identify and understand key factors necessary to develop relevant patient-centered interventions. Participants were recruited from pharmacies throughout Namibia. Data were analyzed using thematic analysis from the transcribed interviews. RESULTS A total of 23 interviews were conducted, with 20 being included in the final analysis. Themes identified included: 1) participants were motivated to seek care when they were symptomatic; 2) participants felt motivated to care for their condition to improve their own lives and their families for their family's sake; 3) participants integrated information from a variety of sources into their disease knowledge; 4) participants describe wanting to be more engaged in managing their health and wanting support to help manage their condition; 5) participants describe awareness of lifestyle changes necessary to improve health, but face many barriers to achieving them. CONCLUSION This study identified key factors that are essential for pharmacists and other health care professionals to be aware of in order to support patients who are diagnosed with an NCD. Health care providers should consider strategies to engage patients to harness their motivations, enhance health education, and create systems to reduce barriers to addressing lifestyle.

The role of the University of Cape Town, South Africa in the training and retention of surgeons in Sub-Saharan Africa. Am J Surg 2020; 220:1208-1212. [PMID: 32771217 DOI: 10.1016/j.amjsurg.2020.06.070] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2020] [Revised: 04/22/2020] [Accepted: 06/26/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Sub-Saharan Africa (SSA) has a shortage of surgeon specialists. Many SSA countries lack specialty training programs but South Africa, an upper middle-income country, has several post-graduate surgical training programs. The primary objective of this study was to describe the retention rates of non-South African SSA surgical trainees from the University of Cape Town (UCT) on the African sub-continent. The secondary objective was to describe advantages and disadvantages of foreign surgical trainees on the UCT surgical training programs. METHODS This was a two-part cross-sectional survey administered via email between June 1, 2018 and March 1, 2019 to UCT 1) surgical residents and fellows who graduated between 2007 and 2017 and whose country of origin was in SSA but outside South Africa, and 2) UCT surgical division heads. RESULTS Thirty out of 78 (38%) trainees responded; 83% (n = 25) were male. There was a 96% retention rate of surgical trainees in SSA, 80% (n = 24) returned to their country of origin after training, 83% (n = 25) worked in the public sector, and 90% (n = 27) in teaching hospitals. Seven out of ten surgical division heads responded. Reported advantages of SSA trainees included more junior staff (n = 5, 71%) and the establishment of SSA networks (n = 4, 57%). Disadvantages included increased training responsibilities for educators (n = 2, 29%) and fewer cases for South African trainees (n = 2, 29%). DISCUSSION Retention on the African sub-continent of surgeons who trained at UCT was high. SSA doctors can utilize South African post-graduate surgical training programs until their own countries increase their training capacity. The majority of trainees returned to their countries of origin, utilizing their skills in the public and academic sectors, and contributing to the teaching of more trainees. These training partnerships also contribute to knowledge-sharing and facilitate a regional network of African surgeons. Active recruitment of more female trainees is needed to ensure gender equity.

A qualitative enquiry into the meaning and experiences of wellbeing among young people living with and without HIV in KwaZulu-Natal, South Africa. Soc Sci Med 2020; 258:113103.

Abstract
Young people in sub-Saharan Africa encounter health and livelihood challenges which may compromise their wellbeing. Understanding how young people's wellbeing is defined could strengthen wellbeing policies. We investigated perceptions and experiences of young people's wellbeing, and whether these aligned with Ryff's psychological wellbeing (PWB) model. Data were collected between January-August 2018 through focus-group discussions (n = 12) and in-depth interviews (n = 16) with young people living with and without HIV, selected purposively from South African healthcare facilities. Key informant interviews (n = 14) were conducted with healthcare workers and subject-matter experts. Using a framework approach, we situated our analysis around dimensions of Ryff's PWB model: autonomy, self-acceptance, purpose in life, environmental mastery, positive relationships, personal growth. Young people's wellbeing was rooted in family and peer relationships. Acceptance and belongingness received from these networks fostered social integration. HIV-related stigma, crime and violence reduced their perceived control and social trust. For males, fulfilling gendered roles made them feel socially valued. Self-perceived failure to uphold sexual norms undermined women's social contribution and autonomy. Social integration and contribution framed young people's wellbeing. However, these dimensions were not fully captured by Ryff's PWB model. Models that consider relationality across socio-ecological levels may be relevant for understanding young people's wellbeing.

A predictive model and socioeconomic and demographic determinants of under-five mortality in Sierra Leone. Heliyon 2020; 6:e03508. [PMID: 32181389 PMCID: PMC7063153 DOI: 10.1016/j.heliyon.2020.e03508] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Revised: 10/23/2019] [Accepted: 02/25/2020] [Indexed: 12/20/2022] Open
Abstract
Sierra Leone is among the countries that recorded high under-five child mortality rate in the world. To design and implement policies that can address this public health challenge, the present study developed a predictive model of factors that explained under-five mortality in Sierra Leone using the 2008 and 2013 Sierra Leone Demographic and Health Survey (SDHS) datasets. LASSO regression technique was used to select the predictors to build the under-five predictive single-level logit and multilevel logit models. Statistical analyses were performed in the R freeware version 3.6.1. About 588 (10.4%) and 1320 (11.1%) children under five were reported dead in 2008 and 2013, respectively. The significant predictors of under-five mortality in Sierra Leone were the total number of children ever born, number of children under five in the household, mother's birth in the last five years, mother's number of living children, and number of household members, household wealth, maternal contraceptive use and intention, number of eligible women in the household, type of toilet facility, sex of the child, and weight of the child at birth. The study identified certain predictors that deserve policy attention and interventions to strengthen the efforts of creating child welfare and survival atmosphere in Sierra Leone.
