ABSTRACT

In this paper, we compare the pandemic management performance of 22 countries that belong to the middle-high income class based on criteria including the pandemic data, population characteristics, and health system capacity. The management of the COVID-19 pandemic requires considering many and often conflicting aspects at the same time which necessitates an MCDM approach. We use a standard deviation (SDV) based range of value (ROV) method which coincides with the black-box nature of the disease. The weights obtained from the SDV method reveal that the number of COVID-19 deaths, current health expenditure, and deaths due to cardiovascular diseases are the most important criteria. The ROV method indicates that most Asian countries are ranked in higher positions due to their strong healthcare systems and quick implementation of social distancing rules. The lowest performances belong to Bulgaria, Montenegro, and Bosnia and Herzegovina. They have experienced an elevated number of deaths due to having an elderly population and inefficient usage of healthcare resources. We also show that extreme poverty is an important determinant of country performance. In countries where poverty is higher, as the case with Indonesia, implementing the social distancing rules becomes almost impossible which affects the overall country performance significantly. © 2021 by the authors.

ABSTRACT

This study aimed to evaluate the chest Computed Tomography (CT) scans of COVID-19 suspected patients in the first period of the pandemic, to reveal the frequency of parenchymal-extraparenchymal incidental findings (IFs). Our single-center retrospective observational study was initiated with the approval of the ethics committee. Chest CT records taken during March-August 2020 due to the suspicion of COVID-19 pneumonia were scanned using the imaging archive of our center. The study was conducted with 1540 patients with non-contrast chest CT without prior CT imaging to detect IFs. Histopathological results and clinical-radiological follow-up data of the patients were scanned from medical records. Of the 1540 patients in our study, 902 (58.57%) were male and 638 (41.43%) were female, with a mean age of 41.96±17.08 (5-92) years. While 248 (16.1%) patients had a typical appearance for COVID-19 pneumonia on thorax CT, no findings were found in 1180 (76.6%) patients. Except for COVID-19 pneumonia, parenchymal IFs(primary malignant lung lesions, metastatic lesions, benign pathologies) were detected in 73 patients (4.74%) and extraparenchymal IFs(lymphadenopathy, breast lesions, thyroid nodule, bone, liver and kidney lesions…) in 280 patients (18.8%). Our study showed that the number of patients without any findings in terms of COVID-19 pneumonia on CT scans is high. It is understood that CT scans for pneumonia are unnecessary due to radiation exposure and should be used when clinically necessary. However, due to the ability of CT to detect incidental findings, it is also important to define IFs oth er than pneumonia in patients who underwent chest CT examination during the pandemic.

ABSTRACT

Several legal amendments regarding the economic life in Turkey have been made to prevent the negative impacts of the coronavirus disease 2019 (COVID-19). The Provisional Article 13 of the Turkish Commercial Code (TCC) has been adopted due to the precautionary principle. This regulation aims to keep the equity of stock corporations within the company during this epidemic. The provision aims to ensure the continuity of the stock corporations in our country by overcoming the COVID-19 pandemic with minimum damage. According to the provision, for a certain period of time, the corporations can only distribute their net profits for the fiscal year of 2019 up to 25%, cannot subject the previous years' dividends and distributable reserves to distribution, and cannot give authority to their governing bodies to distribute advance dividend. The enforcement date of the provision has initiated new discussions in Turkish law about the validity and execution of general assembly resolutions. This study examines the principle of capital maintenance and possible problems regarding the outcome of the general assembly resolution about distribution after determining the basic concepts, scope, and execution area of the TCC's Provisional Article 13.
