Item Hearing impairment among chronic kidney disease patients on haemodialysis at a tertiary hospital in Ghana(Ghana Medical Journal, 2019-09) Boateng, J.O.; Boafo, N.; Osafo, C.; Anim-Sampong, S.Background: Chronic kidney disease is a major public health challenge, globally. Inadequate excretion of metabolic waste products by the kidneys results in circulation of these toxic materials in the body. This can cause damage to tissues and organ systems including the auditory system which can lead to hearing loss. Aim: The study was aimed at determining the prevalence, degrees and types of hearing impairment among Chronic kidney disease patients on haemodialysis in Ghana. Methods: A case-control study involving 50 Chronic Kidney disease patients and 50 age and gender-matched control group was carried out at the Korle Bu Teaching Hospital (KBTH). A structured questionnaire was administered to obtain basic socio-demographic data and case history of the participants. Audiological assessment was performed using a test battery comprising otoscopy, tympanometry and pure tone audiometry in a soundproof booth. Results: Higher hearing thresholds were recorded across all the frequencies tested among the case group than the control group (p < 0.05) in both ears. Only sensorineural hearing loss was identified among the cases. The prevalence of hearing loss was 32% among the case group and 12% among the control group. No significant association was observed between hearing loss and duration of Chronic kidney disease (p = 0.16), gender of Chronic kidney disease patient and hearing loss (p = 0.88), and duration of Chronic kidney disease and degree of hearing loss (p=0.31). Conclusion: Our study showed that Chronic Kidney disease patients on haemodialysis are at higher risk of experiencing hearing loss.Item The Impact of Exchange Rate Fluctuations on Firms Financial Performance: A Case Study of Some Selected Manufacturing Firms in Ghana.(University of Ghana, 2019-07) Boateng, J.O.The Ghanaian economy has for some time witnessed a seemingly unstable exchange rate. The strength of the cedi against the dollar has been fluctuating for the past decades. Analysts established that the instability in the exchange rate stems from the massive importation of goods and services which could be produced in the country. The worsening and unstable strength of the cedi against major currencies like the US dollar has contributed immensely to the rise in the cost of goods and services in Ghana. Firms that engage in international trade are hard hit with this occurrence. Manufacturing firms whose inputs are mostly imported from other countries are mostly at the receiving end. This study therefore found it expedient to employ panel data analysis to examine how fluctuations in the exchange rate has had impact on the financial performance of some selected firms and the manufacturing industry in general. The study observed that apart from Real Exchange Rate which is the variable of interest in this study, GDP and Interest Rate are the variables which have significant impact on both ROA and ROE of the manufacturing firmItem When trash fish is treasure: the case of Ghana in West Africa(Fisheries Research (96): 167-172, 2009) Nunoo, F.K.E.; Boateng, J.O.; Ahulu, A.M.; Agyekum, K.A.; Sumalia, U.R.
