Chest ultrasonography, intended for lung, pleura, and mediastinum is a safe, non-invasive medical imaging modality in both affluent and resource-limited settings in respiratory diseases detection including pulmonary Tuberculosis. The purpose of this study is to inform clinicians and policymakers on efficient use of thoracic ultrasound in the screening of tuberculosis and to enrich the existing literature on ultrasonography use in pulmonary Tuberculosis management. This was a hospital based cross-sectional study at Baraka Health center-Mathare slum. Patients presenting at the outpatient section irrespective of age were screened to be included in the study. On the first day, participants with suggestive symptoms of tuberculosis were screened by performing a comprehensive respiratory examination, measuring erythrocyte sedimentation rate and performing chest ultrasonography. Exhaustion of study screening protocols ushered in use of Kenya’s ministry of health guidelines in TB diagnosis including a chest x-ray interpreted by a radiologist. Out of 100 participants who met the inclusion criteria 80 (80%) provided consent to be enrolled into the study.  Majority were male 63.8% with a mean age of 35.83 ± 15.6 years. The most prominent thoracic ultrasound features identified were lung cavitation and consolidation (52.8%) pleural thickening (77.4%) and sub-pleural nodes (52.8%). In conclusion, Thoracic ultrasound is a safe and effective procedure to visualize pleural space, mediastinum and lung parenchyma in pulmonary tuberculosis screening. Pleural thickening can be identified by ultrasound in more than 77.4% of PTB patients. For precise diagnosis of pulmonary tuberculosis other supporting investigation are recommended to complement thoracic ultrasonography.            

This research paper electronic banking and economic productivity in Nigeria. Secondary data were sources from CBN statistical bulletin Real Gross Domestic Product (RGDP) and electronic banking (ATM, POSand Mobile banking) for the period of 2009 to 2019. The collected data was analysed using ordinary least square (OLS) regression technique. Findings of the research revealed that ATM and MPS has positive and significant relationship with economic productivity while POS shows negative and inverse relationship with economic productivity. The paper concludes from its findings that electronic bankinghas mixed effect on economic productivity of Nigeria. Thus, while ATMand mobile banking leads to improvements in economic productivity, same cannot be said for point of sales machines which has a negative effect on economic productivity.The study recommends that regulatory authorities should investigate further on the usage of point of sales since it asserts negative effect on economic productivity in Nigeria. The study also proffers that there is need for improvement on the performance of automated teller machine and mobile payment system since they assert positive and significant impact on economic productivity.
