A Bayesian Model for Predicting Road Traffic Fatalities in Ghana

Bayesian model for predicting the annual regional distribution of the number of road traffic fatalities in Ghana is derived, using road traffic accident statistics data from the National Road Safety Commission, Ghana Statistical Service and Driver and Vehicle Licensing Authority. The data span 1991 to 2009. Since the parameters are assumed to vary across the various regions, they are considered to be random variables with probability distributions. The Markov Chain Monte Carlo (MCMC) sampling techniques were used to draw samples from each of the posterior distribution, thereby determining the values of the unknown parameters for each region based on a given data. The study has shown that population and number of registered vehicles are predominant factors affecting road traffic fatalities in Ghana. The effect of other additional factors on road traffic fatality such as human error (due to the driver, passenger and/or pedestrian), vehicle (its condition and maintenance), environmental/weather and nature of the road cannot be ruled out.

Shifting from public shared toilets to home toilets in urban settlements: implications of household demand in Kumasi, Ghana

This study was conducted to assess the households’ attributes towards the use of public toilet, demand for improved household toilet and the implications of shifting from public shared toilet to improved household or home toilet. A sample of 120 houses was randomly selected from two groups – those without improved household toilets and those with improved household toilets built with subsidy. The results showed that most of the households using public toilet (86%) were not satisfied with the cleanliness and odour, but were not aware of the home toilet promotion. High and middle income households (82%) received subsidy of 50% of the cost of household toilet. Most of the low income households residing in multifamilies houses did not have improved household toilet due to limited space for facility, multilandlords from extended families, and lack of motivation resulting from the presence of public shared toilets. There are difficulties in shifting from public shared toilets to improved household toilets

Partnerships in sanitation service management and infrastructure provision in Kumasi, Ghana

This paper investigates the potentials of the private sector in the development and management of sanitation infrastructure and services within three Sub metros in the Kumasi Metropolitan Assembly (KMA). A case study approach was used and data on public toilets under Build-Operate-Transfer (BOT) and franchise management were collected. Results showed that users of BOT facilities were generally satisfied with the services they receive but the KMA-owned toilets under franchised management receive low patronage because of the poor management and political interference. Some factors plaguing the partnership include mistrust between the partners, political interference and socio-cultural behaviour of the users

A review of chest radiographic patterns in mild to moderate novel corona virus disease 2019 at an urban hospital in Ghana

Introduction: The novel corona virus disease 2019 (COVID-19) was diagnosed in Wuhan, China in December 2019 and, in Ghana, in March 2020. As of 30th July 2020, Ghana had recorded 35,142 cases. COVID-19 which can be transmitted by both symptomatic and asymptomatic individuals usually manifest as pneumonia with symptoms like fever, cough, dyspnoea and fatigue. The current non-availability of a vaccine or drug for COVID-19 management calls for early detection and isolation of affected individuals. Chest imaging has become an integral part of patient management with chest radiography serving as a primary imaging modality in many centres.Methods: The study was a retrospective study conducted at Ga East Municipal Hospital (GEMH). Chest radiographs of patients with mild to moderate disease managed at GEMH were evaluated. The age, gender, symptom status, comorbidities and chest x-ray findings of the patients were documented. Results: 11.4 % of the patients had some form of respiratory abnormality on chest radiography with 88.9% showing COVID-19 pneumonia features. 93.8% showed ground glass opacities (GGO), with 3.1% each showing consolidation (CN) only and CN with GGO. There was a significant association between COVID-19 radiographic features and patient’s age, symptom status and comorbidities but not with gender.Conclusion: Most radiographs were normal with only 11% showing COVID-19-like abnormality. There was a significant association between age, symptom status and comorbidities with the presence of COVID-19 like features but not for gender. There was no association between the extent of the lung changes and patient characteristics

PREventing Maternal And Neonatal Deaths (PREMAND): a study protocol for examining social and cultural factors contributing to infant and maternal deaths and near-misses in rural northern Ghana

Plain English Summary The Preventing Maternal And Neonatal Deaths (PREMAND) project works to understand the social and cultural factors that may contribute to the deaths and near-misses (people who almost die but end up surviving) of mothers and babies in four districts in Northern Ghana. Examples of these factors include such thing as treating a sick baby at home with traditional medicine instead of going to a hospital or health center, or pregnant women needing permission from several people before they can go to a hospital to deliver. These social and cultural factors will be placed on a map to understand where patterns and clusters of deaths and near-misses are present in these four communities. The final phase of the project will include support and small grants for community members and local leaders to use these maps and this information to create their own solutions that address the specific needs of each community. Abstract Background While Ghana is a leader in some health indicators among West African nations, it still struggles with high maternal and neonatal morbidity and mortality rates, especially in the northern areas. The clinical causes of mortality and morbidity are relatively well understood in Ghana, but little is known about the impact of social and cultural factors on maternal and neonatal outcomes. Less still is understood about how such factors may vary by geographic location, and how such variability may inform locally-tailored solutions. Methods/Design Preventing Maternal And Neonatal Deaths (PREMAND) is a three-year, three-phase project that takes place in four districts in the Upper East, Upper West, and Northern Regions of Ghana. PREMAND will prospectively identify all maternal and neonatal deaths and ‘near-misses’, or those mothers and babies who survive a life threatening complication, in the project districts. Each event will be followed by either a social autopsy (in the case of deaths) or a sociocultural audit (in the case of near-misses). Geospatial technology will be used to visualize the variability in outcomes as well as the social, cultural, and clinical predictors of those outcomes. Data from PREMAND will be used to generate maps for local leaders, community members and Government of Ghana to identify priority areas for intervention. PREMAND is an effort of the Navrongo Health Research Centre and the University of Michigan Medical School. Discussion PREMAND uses an innovative, multifaceted approach to better understand and address neonatal and maternal morbidity and mortality in northern Ghana. It will provide unprecedented access to information on the social and cultural factors that contribute to deaths and near-misses in the project regions, and will allow such causal factors to be situated geographically. PREMAND will create the opportunity for local, regional, and national stakeholders to see how these events cluster, and place them relative to traditional healer compounds, health facilities, and other important geographic markers. Finally, PREMAND will enable local communities to generate their own solutions to maternal and neonatal morbidity and mortality, an effort that has great potential for long-term impact.http://deepblue.lib.umich.edu/bitstream/2027.42/134530/1/12978_2016_Article_142.pd

Application of a value chain approach to understanding white kenkey production, vending and consumption practices in three districts of Ghana

Traditional processing and street vending of foods is a vital activity in the informal sector of the Ghanaian economy and offers livelihood for a large number of traditional food processors. Kenkey is a fermented maize ‘dumpling’ produced by traditional food processors in Ghana. Ga and Fante kenkey have received research attention and there is a lot of scientific information on kenkey production. White kenkey produced from dehulled maize grains is a less known kind of kenkey. A survey was held in three districts of Ghana to study production, vending and consumption of white kenkey and to identify major bottlenecks related to production, which can be addressed in studies to re-package kenkey for a wider market. Questionnaires were designed for producers, vendors and consumers of white kenkey to collate information on Socio-cultural data, processing technologies, frequency of production and consumption, product shelf life, reasons for consumption and quality attributes important to consumers using proportional sampling. The survey was conducted in white kenkey production zones and trade centers. Results showed that production of white kenkey is done on small-scale levels by middle-aged women in households with 10-50 kg of dehulled maize processed into white kenkey, 1-3 times weekly. A third (28%) of the women processed up to 50-100 kg of maize per week. Although 62% of vendors sell 50-100 balls of white kenkey daily, 15% of them sell more than 170 balls. Majority of consumers (45.9%) liked white kenkey because of its convenience (ready-to-eat). Texture and taste were quality attributes desired by kenkey consumers. Producers did not have written records of process controls and product throughputs. Inspite of their cottage nature, production of white kenkey is a profitable employment for producers and vendors and is popular among consumers. Product improvement, process and product characteristics could offer scale-up criteria for development of white kenkey production using standardized procedures for steeping times, steeping temperature and fermentation times.Keywords: maize, white kenkey, value chain, traditional, product development, re-engineerin

Chemical, functional and pasting properties of starches and flours from new yam compared to local varieties

Open Access Journal; Published online: 14 Jul 2022The potential uses of starches and flours depend on their physicochemical and functional properties. The chemical composition, functional and pasting properties of starch and flours obtained from some newly developed yam varieties from the Crops Research Institute (CRI), Ghana were evaluated, and compared with the existing local varieties. The results showed that the physicochemical and functional properties varied among the varieties studied. The CRI varieties were grouped in a principal component analysis as moisture (afase pa), amylose content (ahodenfo, soanyinto, afase biri), high starch content, bulk density and water absorption capacity (kukrupa, Mankrong pona, CRI pona). Starch pasting characteristics showed that Mankrong pona, CRI pona and afase pa exhibited stable pastes whereas afase biri, Mankrong pona and, afase soanyinto could be utilized for high-temperature processing. Overall, the new CRI varieties showed considerable functionalities that could be explored for potential food and industrial applications as compared to the existing local varieties

Hiv/Aids prevalence at the accident & emergency centre of a tertiary and referral health institution in Ghana

Background: Ghana has an estimated HIV prevalence of 1.4%, but the HIV prevalence of patients presenting at emergency departments in Ghana is not well documented in published literature. This study evaluated the prevalence of HIV infection at the Accident & Emergency Department, Komfo Anokye Teaching Hospital (KATH A&E), Kumasi, Ghana.Methods: A descriptive cross-sectional survey was carried out on patients aged 18 and above presenting to KATH A&E. An opt-in testing approach was used; consenting patients were screened for HIV using rapid HIV finger-stick testing with HIV 1-2 STAT-PAK. Sero-positivity was confirmed by OraQuick HIV 1-2 test. Data was analysed using multivariate logistic regression.Results: 1125 patients presenting at the KATH A&E during the study period were offered the Rapid HIV test. 667 of these patients consented to have the test. HIV prevalence was 13.5% (90/667). 53 females (58.9%) were HIV positive compared to 37 males (41.1%). The age group 30-50 years had the highest risk of being HIV-positive. Other socio-demographic variables such as educational level and occupation were significantly associated with HIV-infection (Pvalue = 0.001 at 95% CI).Conclusion: This study shows that emergency department HIV testing in Ghana is feasible. The prevalence of HIV sero-positive patients presenting at KATH A&E was tenfold higher than national estimates. We conclude that this study showed a high prevalence among patients seeking emergency care in our setting. Testing in the emergency department could lead to early detection of HIV-infected patients for linkage to care.Keywords: HIV Infections; HIV Screening; Prevalence, Diagnosis, Emergency Departmen

Yam pectin and textural characteristics: a preliminary study

Open Access Journal; Published online: 05 Jul 2022The texture of yams is a key determinant in the selection of yams for boiled and pounded yams. This study was conducted to quantify pectin from local and newly developed yam varieties and to correlate pectin and its degree of esterification (DE) with instrumental textural profile parameters of boiled and pounded yam. Isolation of pectin from yam cell wall material (CWM) was achieved with citric acid and the degree of esterification (DE) was determined. The textural parameters were obtained using a texture analyzer. All the new D. rotundata (Poir) varieties had low CWM which varied from 11.88 to 18.95% compared to the D. alata varieties which ranged from 27.60 to 32.79%. Pectin yield (%) for CRI D. alata varieties ranged from 4.47 to 11.35 while CRI D. rotundata (Poir) varieties ranged from 5.18 to 5.50%. Generally, CRI D. alata yam varieties had higher pectin than D. rotundata (Poir) varieties. The DE for all samples ranged from 22.54 to 51.37%, making yam pectin low methoxy. Positive correlations existed between the textural parameters and pectin content as well as the DE but were not significant (p > .05). This study shows that low methoxy yam pectin has no effect on textural characteristics of boiled and pounded yam

Gender-disaggregated consumer testing and descriptive sensory analysis of local and new yam varieties

Open Access JournalGender-disaggregated sensory evaluation has become an essential element that could enhance breeding activities by increasing the adoption of new varieties. The effect of age, sex and geographical location on descriptor preferences for boiled and pounded yam were studied using descriptive and consumer testing. Attributes with definitions and measurement scales were used to generate lexicons for boiled and pounded yam. Analytical tools employed for the inferential statistics were the independent t-test, analysis of variance, Kruskal–Wallis test, Mann–Whitney test and relative importance index (RII). Descriptive testing showed that all the D. rotundata varieties were good for boiling and pounding. The D. alata varieties afase soanyinto and afase biri were most liked, while afase pa and ahodenfo were disliked. Age had no significant effect on descriptor preferences. Being a female or male, however, influenced preferences for pounded yam descriptors such as mouldability, lumpiness and colour. The RII for the D. rotundata varieties (0.22–0.28) showed that they are all good varieties for boiling and pounding. The local D. alata varieties were still highly acceptable compared the new CRI varieties due to the aroma. Rural consumers preferred all the descriptors of boiled D. rotundata than urban consumers, whereas urban consumers liked the pounded yam varieties better than the rural consumers. Availability of the new yam varieties on local markets could therefore increase consumption and improve adoption
