    Background Blood group O protects African children against severe malaria and has reached high prevalence in malarious regions. However, its role in malaria in pregnancy is ambiguous. In 839 delivering Ghanaian women, associations of ABO blood groups with Plasmodium falciparum infection were examined. Methods Plasmodium falciparum infection was diagnosed in placental blood samples by microscopy and PCR assays. Present or past infection was defined as the detection of parasitaemia or haemozoin by microscopy, or a positive PCR result. Blood groups were inferred from genotyping rs8176719 (indicating the O allele) and rs8176746/rs8176747 (distinguishing the B allele from the A allele). Results The majority of women had blood group O (55.4%); present or past P. falciparum infection was seen in 62.3% of all women. Among multiparae, the blood groups had no influence on P. falciparum infection. In contrast, primiparae with blood group O had significantly less present or past infection than women with non-O blood groups (61.5 vs 76.2%, P = 0.007). In multivariate analysis, the odds of present or past placental P. falciparum infection were reduced by 45% in blood group O primiparae (aOR, 0.55 [95% CI, 0.33–0.94]). Conclusions The present study shows a clear protective effect of blood group O against malaria in primiparae. This accords with findings in severe malaria and in vitro results. The data underline the relevance of host genetic protection among primiparae, i.e. the high-risk group for malaria in pregnancy, and contribute to the understanding of high O allele frequencies in Africa

    Objectives - To explore the degree of agreement on issues surrounding the proposals for dental health personnel requirements among key oralhealth personalities who are central to determining policy on oral health personnel requirements for Ghana and to make recommendations to assist in the future development of dental health personnel requirements. Design - A review of the literature, published documents and in-depth semi-structured interviews. Setting – Dental health service in Ghana Participants - Key oral health personalities who are central to determining policy on oral health personnel requirements for Ghana Results - There was a lack of consensus regarding key aspects of planning personnel requirements including the numbers and the kinds of professionals complementary to dentistry (PCDs) to develop, who should be responsible for their training, and which people to admit as trainees of PCDs. Conclusion - Greater discussion between the various agencies involved should take place to help ensure consensus on the overall policy objectives

    In developing countries modern medicines are often beyond the affordability of the majority of the population. This is due to the reliance on expensive imported raw materials despite the abundance of natural resources which could provide an equivalent or even an improved function. The aim of this study was to investigate the potential of sesamum gum (SG) extracted from the leaves of Sesamum radiatum (readily cultivated in sub-Saharan Africa) as a matrix former. Directly compressed matrix tablets were prepared from the extract and compared with similar matrices of HPMC (K4M) using theophylline as a model water soluble drug. The compaction, swelling, erosion and drug release from the matrices were studied in deionized water, 0.1 N HCl (pH 1.2) and phosphate buffer (pH 6.8) using USP apparatus II. The data from the swelling, erosion and drug release studies were also fitted into the respective mathematical models. Results showed that the matrices underwent a combination of swelling and erosion, with the swelling action being controlled by the rate of hydration in the medium. SG also controlled the release of theophylline similar to the HPMC and therefore may have use as an alternative excipient in regions where Sesamum radiatum can be easily cultivated

    Coping with adversity: Resilience dynamics of livestock farmers in two agroecological zones of Ghana

    Despite the increasing occurrence of adverse events including droughts and conflicts, livestock farmers in Ghana continue to raise animals to support their livelihoods and the national economy. We assessed the resilience of cattle farmers (CF) to adverse events they faced using a cross-sectional survey of 287 CF in two agroecological zones in Ghana. Resilience to adversities was assessed using the Resilience Scale (RS-14). Resilience scores and categories were computed and factors that explained variations in resilience categories assessed. The farmers kept, on average, 31 cattle per household, with a majority (91%) also growing crops. Key adverse events confronting them in both districts were animal disease outbreaks, pasture shortages, and theft, with 85% (240/287) losing, on average, seven cattle (15% of the herd size) over a one-year period. The mean resilience score was 71 (SD = 8) out of 98; 52% were highly resilient. Resilience was higher in the southern district (72 versus 70), albeit not statistically significant (p = 0.06). The resilience significantly improved with age, each unit increase in cattle in the herd, and having experience raising livestock (p < 0.001). The CF have relatively high resilience to adverse events affecting their productivity. The findings provide relevant information for implementing mitigation measures to improve production by reducing animal mortalities through high-quality veterinary services

    An ecological correlation study of the prevalence of hypertension with human immunodeficiency virus (HIV) prevalence in sub-Saharan Africa was conducted to determine the extent to which these conditions coincide at country level. Data on prevalence of hypertension were derived from a systematic search of literature published between 1975 and 2014 with corresponding national estimates on HIV prevalence and antiretroviral therapy (ART) coverage from the Demographic and Health Surveys and the joint United Nations Programme on HIV/AIDS databases. National estimates on gross national income (GNI) and under-five mortality were obtained from the World Bank database. Linear regression analyses using robust standard errors (allowing for clustering at country level) were carried out for associations of age-standardised hypertension prevalence ratios (standardized to rural Uganda’s hypertension prevalence data) with HIV prevalence, adjusted for national indicators, year of study and sex of the study population. In total, 140 estimates of prevalence of hypertension representing 25 nations were sex-and area-matched with corresponding HIV prevalence. A two-fold increase in HIV prevalence was associated with a 9.29% increase in age, sex and study year-adjusted prevalence ratio for hypertension (95% CI 2.0 to 16.5, p = 0.01), which increased to 16.3% (95% CI 9.3 to 21.1) after adjusting for under-five mortality, GNI per capita and ART coverage. Countries with a pronounced burden of HIV may also have an increased burden of non-communicable diseases such as hypertension with potential economic and health systems implications

    Nutrition-sensitive education and social protection policies have implications for food-based dietary guidelines for Ghana

    Get PDF
    Ghana continues to address persistent malnutrition through political action and programme development. Government-led efforts have included the formulation of multi-sectoral policies and programmes to improve the diet and nutritional status of various at-risk population groups. Globally, an important tool for promoting healthy diets are Food-Based Dietary Guidelines (FDBGs). To achieve and sustain the desired goal of promoting healthy eating habits and lifestyles, FBDGs require, among many factors, supportive national policies and programmes. When coherently incorporated in relevant nutrition-related policies and programmes, FBDGs enhance their impact on shaping and sustaining healthier dietary habits. In this context, it is essential to understand the national policy and programme environment and its potential contribution during the formulation of FBDGs. The present review aimed to identify existing nutrition-related education and social protection policies and programmes in Ghana and their relevance to the development and implementation of FBDGs. Previously conducted scoping reviews, gap analyses, and a benchmarking report of Ghana’s public health nutrition policies were used as information sources to identify relevant policies and programmes. Additionally, websites of relevant government ministries, departments and agencies were searched to retrieve applicable policies or actions that were not included in previous reviews. Nutrition-related education policies that were identified primarily support school health services, whereas social protection policies broadly target social assistance, social welfare, social equity and insurancebased policies and programmes. Specific ways these policies and programmes could support the development and implementation of Ghana’s dietary guidelines include embedding FBDGs in the school nutrition curriculum to motivate healthier food choices by schoolchildren and using FBDGs to plan meals provided as part of the country’s school feeding programme. Regarding social protection, existing instruments such as food transfers, social pensions and conditional cash transfers could be aligned with FBDGs to ensure vulnerable households can access foods and follow recommended guidelines. Although some nutrition actions are incorporated in existing policies and programmes, there are opportunities to improve their nutrition sensitivity.&nbsp

    BACKGROUND: Despite global scale up of interventions for Preventing Mother to child HIV Transmissions (PMTCT), there still remain high pediatric HIV infections, which result from unequal access in resource-constrained settings. Sub-Saharan Africa alone contributes more than 90 % of global Mother-to-Child Transmission (MTCT) burden. As part of efforts to address this, African countries (including Ghana) disproportionately contributing to MTCT burden were earmarked in 2009 for rapid PMTCT interventions scale-up within their primary care system for maternal and child health. In this study, we reviewed records in Ghana, on ANC registrants eligible for PMTCT services to describe regional disparities and national trends in key PMTCT indicators. We also assessed distribution of missed opportunities for testing pregnant women and treating those who are HIV positive across the country. Implications for scaling up HIV-related maternal and child health services to ensure equitable access and eliminate mother-to-child transmissions by 2015 are also discussed. METHODS: Data for this review is National AIDS/STI Control Programme (NACP) regional disaggregated records on registered antenatal clinic (ANC) attendees across the country, who are also eligible to receive PMTCT services. These records cover a period of 3 years (2011–2013). Number of ANC registrants, utilization of HIV Testing and Counseling among ANC registrants, number of HIV positive pregnant women, and number of HIV positive pregnant women initiated on ARVs were extracted. Trends were examined by comparing these indicators over time (2011–2013) and across the ten administrative regions. Descriptive statistics were conducted on the dataset and presented in simple frequencies, proportions and percentages. These are used to determine gaps in utilization of PMTCT services. All analyses were conducted using Microsoft Excel 2010 version. RESULTS: Although there was a decline in HIV prevalence among pregnant women, untested ANC registrants increased from 17 % in 2011 to 25 % in 2013. There were varying levels of missed opportunities for testing across the ten regions, which led to a total of 487,725 untested ANC clients during the period under review. In 2013, Greater Accra (31 %), Northern (27 %) and Volta (48 %) regions recorded high percentages of untested ANC clients. Overall, HIV positive pregnant women initiated onto ARVs remarkably increased from 57% (2011) to 82 % (2013), yet about a third (33 %) of them in the Volta and Northern regions did not receive ARVs in 2013. CONCLUSIONS: Missed opportunities to test pregnant women for HIV and also initiate those who are positive on ARVs across all the regions pose challenges to the quest to eliminate mother-to-child transmission of HIV in Ghana. For some regions these missed opportunities mimic previously observed gaps in continuous use of primary care for maternal and child health in those areas. Increased national and regional efforts aimed at improving maternal and child healthcare delivery, as well as HIV-related care, is paramount for ensuring equitable access across the country

    Background: West African immigrants in Europe are disproportionally affected by metabolic conditions compared to European host populations. Nutrition transition through urbanisation and migration may contribute to this observations, but remains to be characterised. Objective: We aimed to describe the dietary behaviour and its socio-demographic factors among Ghanaian migrants in Europe and their compatriots living different Ghanaian settings. Methods: The multi-centre, cross-sectional RODAM (Research on Obesity and Diabetes among African Migrants) study was conducted among Ghanaian adults in rural and urban Ghana, and Europe. Dietary patterns were identified by principal component analysis. Results: Contributions of macronutrient to the daily energy intake was different across the three study sites. Three dietary patterns were identified. Adherence to the 'mixed' pattern was associated with female sex, higher education, and European residency. The 'rice, pasta, meat, and fish' pattern was associated with male sex, younger age, higher education, and urban Ghanaian environment. Adherence to the 'roots, tubers, and plantain' pattern was mainly related to rural Ghanaian residency. Conclusion: We observed differences in food preferences across study sites: in rural Ghana, diet concentrated on starchy foods; in urban Ghana, nutrition was dominated by animal-based products; and in Europe, diet appeared to be highly diverse

    This study was aimed to describe the outcomes of a hypertension treatment programme in two outpatient clinics in Cambodia. We determined proportions of patients who met the optimal targets for blood pressure (BP) control and assessed the evolution of mean systolic and diastolic BP (SBP/DBP) over time. Multivariate analyses were used to identify predictors of BP decrease and risk factors for LTFU. A total of 2858 patients were enrolled between March 2002 and June 2008 of whom 69.2% were female, 30.5% were aged >/=64years and 32.6% were diabetic. The median follow-up time was 600 days. By the end of 2008, 1642 (57.4%) were alive-in-care, 8 (0.3%) had died and 1208 (42.3%) were lost to follow-up. On admission, mean SBP and DBP were 162 and 94 mm Hg, respectively. Among the patients treated, a significant SBP reduction of 26.8 mm Hg (95% CI: 28.4-25.3) was observed at 6 months. Overall, 36.5% of patients reached the BP targets at 24 months. The number of young adults, non-overweight patients and non-diabetics reaching the BP targets was more. Older age (>64 years), uncontrolled DBP (>/=90 mm Hg) on last consultation and coming late for the last consultation were associated with LTFU, whereas non-diabetic patients were 1.5 times more likely to default than diabetics (95% CI: 1.3-1.7). Although the definite magnitude of the BP decrease due to antihypertension medication over time cannot be assessed definitely without a control group, our results suggest that BP reduction can be obtained with essential hypertension treatment in a large-scale programme in a resource-limited setting
