The determinants of pottery demand in Ghana

The pottery industry in Ghana has been experiencing low demand for its products due to the influx of plastic products and other substitutes. Empirical studies reveal that consumers prefer these traditional products for their domestic and aesthetic uses. This paper examined the determinants of pottery demand in Ghana. Two pottery centres each in five regions in Ghana in addition to 1421 pottery consumers were randomly selected for the study. Using descriptive statistics under the qualitative and quantitative research designs, the study revealed that price of pottery products and their availability play a very significant role in determining demand. Results on quality and perceived purpose or function of pottery products are however mixed. Keywords: Pottery; demand; determinants; Ghan

Re-evaluating the effi cacy of the aqueous leaf extract of Bridelia ferrugenia and its potential combination with metformin in the management of diabetes mellitus

Herbal medicinal products play a significant role in the management of diabetes and other chronic diseaseseither as a monotherapy or in combination with allopathic treatments. The hypoglycemic activity of a Ghanaianherbal antidiabetic product (Bridelia Tea) prepared from the dried leaves of Bridelia ferrugenia [BRD] was reevaluatedin this study with the view of improving, its activity and explore the possible benefit of using theproduct in combination with metformin (MET). Male and female Sprague-Dawley rats (210-220 g) were renderedhyperglycemic by a single intraperitoneal administration of streptozocin (70 mg/kg) after an overnight fast. Thehyperglycemic rats then received one of the following treatments ([BRD 30 mg/kg or 300 mg/kg], [MET 250 mg/kgor 1000 mg/kg], [MET 250 mg/kg and BRD 30 mg/kg], [MET 1000 mg/kg and BRD 300 mg/kg]). The hypoglycemiceffect of BRD, MET, and the combination of the two products were not significantly different during an initial6 h of monitoring (P > 0.05). In the long-term study over 28 days, BRD 300 mg/kg had hypoglycemic effectscomparable to MET 1000 mg/kg p.o. and better than BDF 30 mg/kg p.o. (P < 0.05). However, the combination ofthe two products BRD and MET at the two doses reduced their therapeutic effect compared to animals receivingeither one of the two treatments alone

Associations of blood glucose levels with some diabetes risk factors (body mass index, blood pressure and total body fat) in inhabitants of Ho Municipality, Ghana: a cross-sectional survey

One complex metabolic disorder that can unenviably affect the normal human physiology is diabetes mellitus (DM). It is indeed one of the commonest noncommunicable diseases that has heightened to an epidemic level worldwide. For diseases like DM, hypertension, cardiovascular disease, type II DM, and other chronic diseases, body mass index (BMI) is identified as a positive and independent risk factor associated with morbidity and mortality. The objective of the study was to determine the relationships between BMI, blood pressure, and total body fat among inhabitants of periurban Ho, Ghana. A cross-sectional survey was carried out between May and June, 2018, among 132 inhabitants of Ho to determine the prevalence and associations among DM risk factors. The participants were selected by systematic random sampling. Standardized international protocols were used to measure BMI, blood pressure, blood glucose, and total body fat. Out of 132 respondents, majority 96 (72.7%) were female and the most common age group was 54-60 (31.1%). From the BMI classifications, 65 (49.2%) people were of normal weight while 6 (4.5%) were underweight. Total body fat (%) and blood pressure, likewise total body fat and BMI recorded significant associations of values (0.299, p<0.001-systolic; 0.298, p=0.001-diastolic), and 0.585 (p<0.001), respectively. On the contrary, there were insignificant associations found between blood glucose and diastolic blood pressure and also blood glucose and systolic blood pressure (0.100, p=0.253) and (0.057. p=0.514), respectively using the Spearman’s correlation analysis. Lastly, the test of association of socio-demographics and anthropometrics revealed there was a significant (p<0.001) correlation between total body fat and BMI using Pearson’s correlation analysis. BMI is closely related to total body fat and blood pressure; hence, education on lifestyle modification needs to be intensified to create awareness among the inhabitants of Ho municipality of Ghana. It is imperative to educate Ghanaians and beyond about the risk factor associations that predispose an individual to DM

Five Years Of Family Medicine Undergraduate Education In Ghana: A Wake-Up Call!

Objectives: Given the introduction in 2008 of undergraduate family medicine in the University of Ghana, the study aimed to identify the perceptions of medical students in Ghana about family medicine with regard to knowledge and relevance as well as specialty preferences.Design: A cross-sectional surveyMethod: Investigators conducted yearly surveys of first clinical year students at the University of Ghana School of Medicine and Dentistry over a 5-year period (2008-2012) using a semi-structured questionnaire. Data was analysed using the first class group as baseline for comparison.Main outcome measures: Trends in respondents’ awareness of different aspects of family medicine, their attitudes towards the specialty and their expressed preference or lack of preference for family medicine as a potential specialty for themselves.Results: Over the five-year period, 748 of 893 eligible first year students participated which comprised 84% of students. Awareness of family medicine as a medical specialty remained high but insignificantly declined over the period of study (88% to 80%, p=0.058). Preference for family medicine as career choice remained low at 4%, but an increase from 2% baseline though insignificant (p=0.397). The primary reason for not listing family medicine as career choice was unfamiliarity with the specialty (80%).Conclusion: Although awareness of family medicine among medical students in Ghana remains relatively high, their knowledge is insufficient to influence their career decisions for family medicine. This is a wake-up call!Funding: None declaredKeywords: education, family medicine, Ghana, primary care, undergraduat

Retinopathy in severe malaria in Ghanaian children - overlap between fundus changes in cerebral and non-cerebral malaria

<p>Abstract</p> <p>Background</p> <p>In malaria-endemic areas, reliably establishing parasitaemia for diagnosis of malaria can be difficult. A retinopathy with some features unique to severe malaria with a predictive value on prognosis, has been described. Detection of this retinopathy could be a useful diagnostic tool. This study was designed to determine the diagnostic usefulness of retinopathy on ophthalmoscopy in severe malaria syndromes: Cerebral malaria (CM) and non-cerebral severe malaria (non-CM), i.e. malaria with respiratory distress (RD) and malaria with severe anaemia (SA), in Ghanaian children. Secondly, to determine any association between retinopathy and the occurrence of convulsions in patients with CM.</p> <p>Methods and subjects</p> <p>A cross-sectional study of consecutive patients on admission with severe malaria who were assessed for retinal signs, at the Department of Child Health, Korle-Bu Teaching Hospital, Accra, from July to August 2002 was done. All children had dilated-fundus examination by direct and indirect ophthalmoscopy.</p> <p>Results</p> <p>Fifty-eight children aged between six months and nine years were recruited. Twenty six(45%) had CM, 22 with convulsion; 26(45%) had SA and six(10%) had RD.</p> <p>Any retinopathy was seen in: CM 19(73%), SA 14(54%), RD 3(50.0%), CM with convulsion 15(68%) and CM without convulsion 4(100%). Comparison between CM versus non-CM groups showed a significant risk relationship between retinal whitening and CM(OR = 11.0, CI = 2.2- 56.1, p = 0.001). There was no significant association with papilloedema(OR = 0.9, CI = 0.3 - 3.0, p = 0.9), macular whitening(OR = 1.6, CI = 0.5 - 4.8, p = 0.4), macular haemorrhage(OR = 0.28, CI = 0.03 - 2.7 p = 0.2), retinal haemorrhage(OR = 1.9, CI = 0.6 - 5.6, p = 0.3), vessel abnormality(OR = 1.9, CI = 0.6 - 6.1, p = 0.3) and cotton wool spots(OR not calculated, p = 0.08).</p> <p>Tortuous and engorged retinal veins, not previously described as a feature of CM, was the most common vascular abnormality(15/58 = 26%) and was detected even in the absence of papilloedema.</p> <p>Conclusion</p> <p>Retinal whitening, a sign suggestive of retinal ischaemia, was significantly more common in CM than in non-CM syndromes. However, the high prevalence of any retinopathy in the latter suggests that the brain and the retina may be suffering from ischaemia in both CM and non-CM.</p

Household food security determinants and nutritional status of inhabitants of a peri-urban community: a case study in the Volta region of Ghana

Food shortages and malnutrition widely persist and continue to be rural peculiarities across the sub-region. A cross-sectional study was conducted in a peri-urban community of Dzodze in the Volta region to ascertain the level of food security as well as the nutritional status of the inhabitants using a random sampling technique. This community-based comparative cross-sectional study conducted from May to July 2018 adopted a multistage random sampling and selected 105 households. Sociodemographic data were collected using a structured questionnaire. Chi-square, Cramer’s-V, and Pearson’s correlations models were used to assess the association of socio-demographic, anthropometric and food frequency data while the Logit model, FSI, HCR were used to measure food security. Over half of the sample (59.6%) were in the normal range of BMI which implied good nutritional status. Remarkably, a majority of those in this normal BMI range 81 (77%) were female. Women aged 41years and above constituted a large portion of study participants (54.3%) of which many 43 (41%) were married. Just 4.8% of this group said they were both separated and cohabited with their partners non-customarily. Data on the frequency of food intake by the community revealed that, a majority of 63.4% of the respondents ate three times a day. Most of the people (77.2%, 68.7%, and 86.9%) ate breakfast, lunch, and supper, respectively, daily over a week. The fallouts from the work showed majority (71.5%) of the respondents were food secure and the remaining (about 28.5%) were food insecure. Factors such as age, gender, educational level, household size, and age were found to be significant predictors that influenced food security of the peri-urban community according to the logit model used. The smallholder households according to the computed food security index of 1.13 and normal range of BMI were identified to be indices of food security.&nbsp

Visual impairment among eye health workers in a tertiary eye centre in Ghana

Objective: To determine causes of visual impairment (VI) among staff of the Eye Centre at the Korle Bu Teaching Hospital.Design: This was a cross-sectional study.Setting: The Eye Centre, Korle Bu Teaching Hospital (KBTH), from October 2016 to March 2017 on all consenting members of staff.Participants: Eighty-four (79.3%) of 106 consenting staff members participated in this study.Data collection/Intervention: A detailed history (demographic, ocular, medical co-morbid conditions), ocular examination and relevant diagnostic investigations were conducted. Interventions initiated included treatment for glaucoma, dry eye and allergic conjunctivitis and spectacles prescription for refractive errors.Main outcomes: Prevalence of avoidable causes of VI (glaucoma, cataract, refractive errors). Secondary outcomes included prevalence of unavoidable causes of VI. Results Eighty-four (79.3%) members of staff participated in this study. Most of the participants were females, 54(64.3 %). Age ranged from 23 to 60 years with an average of 35.8±9.9 years (mean ± SD). Prevalence of VI was 9.5 % (8/84), all due to uncorrected refractive error. Other known causes of VI included open angle glaucoma in 12(14.3 %), macular scar of unknown cause, 1(1.2 %) and sutural cataract, 1(1.2 %) but were all visually insignificant.Conclusions: The prevalence of VI among the staff of the Eye Centre of the KBTH was 9.5 %, all due to refractive errors. Other known causes of avoidable visual impairment and blindness encountered were glaucoma (14.3 %), macular scar (1.2 %) and cataract (1.2 %), all asymptomatic. Routine eye screening should be part of periodic medical examination for employees

Exploring the knowledge and awareness of diabetes mellitus among inhabitants of Ho municipality in Ghana: A cross-sectional study

One of the fast-growing major non-communicable diseases (NCD) that poses a danger to global public health is Diabetes mellitus (DM). Trends in&nbsp; the incidence of DM indicate a disproportionate increase in developing countries due to current rapid demographic transitions from traditional to&nbsp; more westernized and urbanized lifestyles. Knowledge of DM is vital for curbing or control. The objectives of this study were to evaluate the level of&nbsp; knowledge and awareness of DM among the Ho municipality general population, identify areas of deficiency for targeted health education efforts,&nbsp; and identify respondent characteristics that may be associated with knowledge of diabetes. A survey involving 132 respondents (age over 18 years)&nbsp; was conducted in the Ho municipality of the Volta region of Ghana. A 42-item pre-tested questionnaire was administered to participants to evaluate&nbsp; general and specific knowledge and awareness of DM. The Pairwise Multiple Comparison and Fisher’s Exact tests were used to test the hypotheses&nbsp; and associations between the respondents’ knowledge level and groups respectively. Of the 132 respondents, 22% were in the age range of 40-46&nbsp; years; 72.7% were female. Mean over all diabetes knowledge composite score was poor: 32.99% (CI; 27.5, 38.5). Respondents performed best in the&nbsp; symptoms section: mean score was 36.247% (CI; 29.0, 43.4); and worst in the section on complications: mean score was 30.909% (CI; 23.6, 38.2). In&nbsp; multiple linear regression analyses, education level, older age, own self having diabetes, and having a family member/relative/friend with diabetes&nbsp; were significantly associated with knowledge of diabetes. Knowledge of diabetes among the inhabitants of Ho municipality respondents was&nbsp; interpreted as being inadequate 32.99% (CI; 27.5, 38.5). Some deficient portions and factors associated with knowledge of diabetes were identified.&nbsp; Relevant information for targeted health education programs in Ghana and beyond may be considered as one of such benefits of these findings.&nbsp;&nbsp;&nbsp

Automated Detection of Malarial Retinopathy in Digital Fundus Images for Improved Diagnosis in Malawian Children with Clinically Defined Cerebral Malaria

Cerebral malaria (CM), a complication of malaria infection, is the cause of the majority of malaria-associated deaths in African children. The standard clinical case definition for CM misclassifies ~25% of patients, but when malarial retinopathy (MR) is added to the clinical case definition, the specificity improves from 61% to 95%. Ocular fundoscopy requires expensive equipment and technical expertise not often available in malaria endemic settings, so we developed an automated software system to analyze retinal color images for MR lesions: retinal whitening, vessel discoloration, and white-centered hemorrhages. The individual lesion detection algorithms were combined using a partial least square classifier to determine the presence or absence of MR. We used a retrospective retinal image dataset of 86 pediatric patients with clinically defined CM (70 with MR and 16 without) to evaluate the algorithm performance. Our goal was to reduce the false positive rate of CM diagnosis, and so the algorithms were tuned at high specificity. This yielded sensitivity/specificity of 95%/100% for the detection of MR overall, and 65%/94% for retinal whitening, 62%/100% for vessel discoloration, and 73%/96% for hemorrhages. This automated system for detecting MR using retinal color images has the potential to improve the accuracy of CM diagnosis
