    This study examined the perceptions of Basic School (K-9) Teachers in Greater Accra towards continuous professional development programs. In carrying out this research, a descriptive survey design was applied. A survey was designed with Google Forms, and the link was posted to a WhatsApp group of 141 teachers from 63 basic schools in the Greater Accra Region of Ghana who were purposively sampled to participate in the study. All 141 teachers responded to the survey questions.The findings revealed mixed reactions from teachers towards continuous professional development programs/activities in Ghana. Some professional development programs, for instance, ā€œCluster/School Based INSET, ICT Integration in Teaching and Learning, Peer Class Observation, Classroom Management, and Subject Content and Methodology Professional Developmentā€ activities geared toward the needs of teachers therefore effective, whereas ā€œEducational Leadership and School Management, Education of persons with Special Needs, Micro Teaching, and Social Dialogueā€ activities were not geared towards teachers needs therefore ineffective. The findings of this study provide valuable information to policymakers, Educational Administrators, and all stakeholders in Education. Considering the study's findings, conclusions and suggestions were provided.

    The study investigated the effect of cash flow management on financial performance of listed manufacturing firms in Ghana. Specifically, the study examined the effect of operating cash flows, investing cash flows, financing cash flows and free cash flows on financial performance. The study used a panel data of 10 conveniently selected firms over a 7-year period from 2012 to 2018. Pooled Ordinary Least Squares, Fixed Effect and Random Effect Models to analyze the data. The results indicates that operating cash flows has a negative and statistically significant impact on financial performance, investing cash flows does not have any significant effect on financial performance while financing cash flows has a direct and significant effect on financial performance. Lastly, free cash flow was found to have a positive and significant effect on financial performance of listed manufacturing firms in Ghana. The study concludes that policies by investors or equity holders should not focus entirely on investment cash flows but rather, operating cash flows, financing cash flows and free cash flows as they are found to significantly affect financial performance.

    BACKGROUND: Currently in the U.S. it is recommended that tuberculosis screening and treatment programs be targeted at high-risk populations. While a strategy of targeted testing and treatment of persons most likely to develop tuberculosis is attractive, it is uncertain how best to accomplish this goal. In this study we seek to identify geographical areas where on-going tuberculosis transmission is occurring by linking Geographic Information Systems (GIS) technology with molecular surveillance. METHODS: This cross-sectional analysis was performed on data collected on persons newly diagnosed with culture positive tuberculosis at the Tarrant County Health Department (TCHD) between January 1, 1993 and December 31, 2000. Clinical isolates were molecularly characterized using IS6110-based RFLP analysis and spoligotyping methods to identify patients infected with the same strain. Residential addresses at the time of diagnosis of tuberculosis were geocoded and mapped according to strain characterization. Generalized estimating equations (GEE) analysis models were used to identify risk factors involved in clustering. RESULTS: Evaluation of the spatial distribution of cases within zip-code boundaries identified distinct areas of geographical distribution of same strain disease. We identified these geographical areas as having increased likelihood of on-going transmission. Based on this evidence we plan to perform geographically based screening and treatment programs. CONCLUSION: Using GIS analysis combined with molecular epidemiological surveillance may be an effective method for identifying instances of local transmission. These methods can be used to enhance targeted screening and control efforts, with the goal of interruption of disease transmission and ultimately incidence reduction

    Objective: Synedrella nodiflora is traditionally used in the treatment of several ailments. Pharmacologically, this plant has anticonvulsant, sedative, anti-nociceptive and anti-proliferative effects. This study further investigated S. nodiflora for its antioxidant and in vitro inhibition of cancerous cell lines. Methods: Phytochemical assays, and the DPPH radical scavenging method were employed in preliminary screening for antioxidant activities of the crude hydro-ethanolic extract (SNE) and resulting fractions. The potent ethyl acetate fraction (EAF), was further investigated for total phenol and flavonoid contents, reducing power, lipid peroxidation potential, and cytotoxic effects on human breast cancer (MCF-7), leukemic (Jurkat), and normal liver (Changā€™s liver) cell lines. Results: The extract contained phenols, flavonoids, tannins, glycosides, sterols, terpenoids, and alkaloids. It scavenged for DPPH with an IC50 of 114 Āµg/ml, whereas that of EAF was 8.9 Āµg/ml. EAF prevented peroxidation of egg lecithin at an IC50 of 24.01Ā±0.08 Āµg/ml. These IC50s are four and three times lower than the reference standards. EAF produced anti-proliferative effects against MCF-7, and Jurkat cell lines with IC50s of 205.2 and 170.9 Āµg/ml, respectively. EAF had a high IC50 of 252.2 Āµg/ml against Changā€™s liver cells. At 0.1 mg/ml EAF had similar total flavonoid content to SNE, but a significantly higher total phenol content. Conclusion: The ethyl acetate fraction of S. nodiflora, exhibited the most potent antioxidant activity. It inhibited the proliferation of breast and leukemic cancer cell lines, whiles having weak cytotoxic effect on normal liver cells. These can be explored for further drug development

    Most prescribers and patients in Ghana now opt for the relatively expensive artemether/lumefantrine rather than artesunate-amodiaquine due to undesirable side effects in the treatment of uncomplicated malaria. The study sought to determine the existence of substandard and/or counterfeit artemether-lumefantrine tablets and suspension as well as artemether injection on the market in Cape Coast. Six brands of artemether-lumefantrine tablets, two brands of artemether-lumefantrine suspensions, and two brands of artemether injections were purchased from pharmacies in Cape Coast for the study. The mechanical properties of the tablets were evaluated. The samples were then analyzed for the content of active ingredients using High Performance Liquid Chromatography with a variable wavelength detector. None of the samples was found to be counterfeit. However, the artemether content of the samples was variable (93.22%āˆ’104.70% of stated content by manufacturer). The lumefantrine content of the artemether/lumefantrine samples was also variable (98.70%ā€“111.87%). Seven of the artemether-lumefantrine brands passed whilst one failed the International Pharmacopoeia content requirements. All brands of artemether injections sampled met the International Pharmacopoeia content requirement. The presence of a substandard artemether-lumefantrine suspension in the market should alert regulatory bodies to be more vigilant and totally flush out counterfeit and substandard drugs from the Ghanaian market

    Objective This study aimed to evaluate the effect of different levels of exercise on markers of oxidative stress and selected metabolic parameters in Ghanaian young adults. Results Significant increases in a marker of oxidative stress malondialdehyde and antioxidants such as superoxide dismutase and uric acid were observed in the exercisers compared with the inactive group (pā€‰<ā€‰0.05). Total cholesterol and high density lipoprotein levels were significantly different (pā€‰<ā€‰0.05) between the two groups. Positive associations between exercise intensity, antioxidant concentration and malondialdehyde were observed within the exercise group for vigorous exercise with regards to uric acid, superoxide dismutase and malondialdehyde (rā€‰=ā€‰0.512, pā€‰=ā€‰0.004; rā€‰=ā€‰0.810, pā€‰=ā€‰0.001; rā€‰=ā€‰0.715, pā€‰=ā€‰0.001) respectively and moderate exercise vs malondialdehyde (rā€‰=ā€‰0.841, pā€‰=ā€‰0.001) compared to the inactive group. Exercise participants performed more vigorous exercise (pā€‰<ā€‰0.001), moderate exercise (pā€‰<ā€‰0.001) and more walking (pā€‰<ā€‰0.001) compared with the inactive group while the inactive group exhibited more sitting (pā€‰<ā€‰0.001). The study provides a first report on the risk associated with increase in oxidative stress and the importance of walking as a health promotion intervention among young Ghanaian adults

    Developing a modified low-density lipoprotein (M-LDL-C) Friedewaldā€™s equation as a substitute for direct LDL-C measure in a Ghanaian population: a comparative study

    Despite the availability of several homogenous LDL-C assays, calculated Friedewald\u27s LDL-C equation remains the widely used formula in clinical practice. Several novel formulas developed in different populations have been reported to outperform the Friedewald formula. This study validated the existing LDL-C formulas and derived a modified LDL-C formula specific to a Ghanaian population. In this comparative study, we recruited 1518 participants, derived a new modified Friedewald\u27s LDL-C (M-LDL-C) equation, evaluated LDL-C by Friedewald\u27s formula (F-LDL-C), Martin\u27s formula (N-LDL-C), Anandaraja\u27s formula (A-LDL-C), and compared them to direct measurement of LDL-C (D-LDL-C). The mean D-LDL-C (2.47Ā±0.71 mmol/L) was significantly lower compared to F-LDL-C (2.76Ā±1.05 mmol/L), N-LDL-C (2.74Ā±1.04 mmol/L), A-LDL-C (2.99Ā±1.02 mmol/L), and M-LDL-C (2.97Ā±1.08 mmol/L) p \u3c 0.001. There was a significantly positive correlation between D-LDL-C and A-LDL-C (r=0.658, p\u3c0.0001), N-LDL-C (r=0.693, p\u3c0.0001), and M-LDL-C (r=0.693, p\u3c0.0001). M-LDL-c yielded a better diagnostic performance [(area under the curve (AUC)=0.81; sensitivity (SE) (60%) and specificity (SP) (88%)] followed by N-LDL-C [(AUC=0.81; SE (63%) and SP (85%)], F-LDL-C [(AUC=0.80; SE (63%) and SP (84%)], and A-LDL-C (AUC=0.77; SE (68%) and SP (78%)] using D-LDL-C as gold standard. Bland-Altman plots showed a definite agreement between means and differences of D-LDL-C and the calculated formulas with 95% of values lying within Ā±0.50 SD limits. The modified LDL-C (M-LDL-C) formula derived by this study yielded a better diagnostic accuracy compared to A-LDL-C and F-LDL-C equations and thus could serve as a substitute for D-LDL-C and F-LDL-C equations in the Ghanaian population

    Drug discovery research in Ghana, challenges, current efforts, and the way forward

    Get PDF
    We have a long-term vision to develop drug discovery research capacity within Ghana, to tackle unmet medical needs in Ghana and the wider West African region. However, there are several issues and challenges that need to be overcome to enable this vision, including training, human resource, equipment, infrastructure, procurement, and logistics. We discuss these challenges from the context of Ghana in this review. An important development is the universities and research centres within Ghana working together to address some of these challenges. Therefore, while there is a long way to go to fully accomplish our vision, there are encouraging signs

    High prevalence of multidrug-resistant tuberculosis among patients with rifampicin resistance using GeneXpert Mycobacterium tuberculosis/rifampicin in Ghana

    Get PDF
    AbstractObjective/BackgroundDrug-resistant strains of tuberculosis (TB) represent a major threat to global TB control. In low- and middle-income countries, resource constraints make it difficult to identify and monitor cases of resistance using drug susceptibility testing and culture. Molecular assays such as the GeneXpert Mycobacterium tuberculosis/rifampicin may prove to be a cost-effective solution to this problem in these settings. The objective of this study is to evaluate the use of GeneXpert in the diagnosis of pulmonary TB since it was introduced into two tertiary hospitals in Ghana in 2013.MethodsA 2-year retrospective audit of clinical cases involving patients who presented with clinically suspected TB or documented TB not improving on standard therapy and had samples sent for GeneXpert testing.ResultsGeneXpert identified 169 cases of TB, including 17 cases of rifampicin-resistant TB. Of the seven cases with final culture and drug susceptibility testing results, six demonstrated further drug resistance and five of these were multidrug-resistant TB.ConclusionThese findings call for a scale-up of TB control in Ghana and provide evidence that the expansion of GeneXpert may be an optimal means to improve case finding and guide treatment of drug-resistant TB in this setting

    Association between malaria and household air pollution interventions in a predominantly rural area of Ghana.

    BACKGROUND: Though anecdotal evidence suggests that smoke from HAP has a repellent effect on mosquitoes, very little work has been done to assess the effect of biomass smoke on malaria infection. The study, therefore, sought to investigate the hypothesis that interventions to reduce household biomass smoke may have an unintended consequence of increasing placental malaria or increase malaria infection in the first year of life. METHODS: This provides evidence from a randomized controlled trial among 1414 maternal-infant pairs in the Kintampo North and Kintampo South administrative areas of Ghana. Logistic regression was used to assess the association between study intervention assignment (LPG, Biolite or control) and placental malaria. Finally, an extended Cox model was used to assess the association between study interventions and all episodes of malaria parasitaemia in the first year of infant's life. RESULTS: The prevalence of placental malaria was 24.6%. Out of this, 20.8% were acute infections, 18.7% chronic infections and 60.5% past infections. The study found no statistical significant association between the study interventions and all types of placental malaria (ORā€‰=ā€‰0.88; 95% CI 0.59-1.30). Of the 1165 infants, 44.6% experienced at least one episode of malaria parasitaemia in the first year of life. The incidence of first and/or only episode of malaria parasitaemia was however found to be similar among the study arms. CONCLUSION: The findings suggest that cookstove interventions for pregnant women and infants, when combined with additional malaria prevention strategies, do not lead to an increased risk of malaria among pregnant women and infants
