    As coronavirus disease 2019 (COVID-19) spreads across the world, the ongoing clinical trials are leading to a big race worldwide to develop a treatment that will help control the pandemic. Unfortunately, COVID-19 does not have any known effective treatment with reliable study results yet. In this pandemic, there is not a lot of time to develop a new specific agent because of the rapid spread of the disease. The process of developing a vaccine is long and requires hard work. Although the pathophysiology of the disease is not fully understood, some of the proposed treatment alternatives are based on old evidence and some have been used with the idea that they might work owing to their mechanism of action. The efficacy, reliability, and safety of the currently available treatment alternatives are therefore a matter of debate. Currently, the main therapies used in the treatment of COVID-19 are antiviral drugs and chloroquine/hydroxychloroquine. Other proposed options include tocilizumab, convalescent plasma, and steroids, but the mainstay of the treatment in intensive care units remains supportive therapies.

    The Perspective of the Turkish Thoracic Society Members on Institutional Preparedness During the COVID-19 Pandemic in Turkey
    (2021) Sandal, Abdulsamet; Töreyin, Zehra Nur; Saltürk, Cüneyt; Arbak, Peri Meram
    OBJECTIVE: We aimed to evaluate the perspective of the Turkish Thoracic Society (TTS) members regarding institutional preparedness, in terms of administrative measures and availability of personal protective equipment (PPE), in the first and third months of the coronavirus disease 2019 (COVID-19) pandemic in Turkey.MATERIAL AND METHODS: A 22-item online survey was e-mailed between the first and third months to TTS members, and participants’ responses were evaluated.RESULTS: The number of participants was 295 in the first survey and 141 in the second. In the second survey, the percentage of answers implying availability increased in all 18 control measures, 16 of which were statistically significant. However, there were still less than half of the respondents who reported the availability of psychological and behavioral support and some PPE, including respirators, facial protectors, goggles, and gowns. Statistical significance was observed for provision of a waiting area (P = .008), rooms for aerosol-generating procedures (P = .042), and special wards for patients with suspected or definite COVID-19 (P < .001); testing healthcare workers (HCWs) with a history of contact with a COVID-19 case (P < .001); and surveillance of symptomatic HCWs (P = .048), between tertiary vs. primary and secondary healthcare facilities in the first survey, but provision of special wards (P = .002) and supply for aprons (P = .027) in the second survey.CONCLUSION: Our results showed an improvement in control measures in the third month of the pandemic. However, the persistent low availability of psychological and behavioral support and several items of PPE pointed out the need for action. Considering the health and safety of HCWs, the control measures should be actively monitored and deficiencies eliminated

    Unclear Issues Regarding COVID-19

    Scientists from all over the world have been intensively working to discover different aspects of Coronavirus disease 2019 (COVID-19) since the first cluster of cases was reported in China. Herein, we aimed to investigate unclear issues related to transmission and pathogenesis of disease as well as accuracy of diagnostic tests and treatment modalities. A literature search on PubMed, Ovid, and EMBASE databases was conducted, and articles pertinent to identified search terms were extracted. A snow-ball search strategy was followed in order to retrieve additional relevant articles. It was reported that viral spread may occur during the asymptomatic phase of infection, and viral load was suggested to be a useful marker to assess disease severity. In contrast to immune response against viral infections, cytotoxic T lymphocytes decline in SARS-CoV-2 infection, which can be partially explained by direct invasion of T lymphocytes or apoptosis activated by SARS-CoV-2. Dysregulation of the urokinase pathway, cleavage of the SARS-CoV-2 Spike protein by FXa and FIIa, and consumption coagulopathy were the proposed mechanisms of the coagulation dysfunction in COVID-19. False-negative rates of reverse transcriptase polymerase chain reaction varied between 3% and 41% across studies. The probability of the positive test was proposed to decrease with the number of days past from symptom onset. Safety issues related to infection spread limit the use of high flow nasal oxygen (HFNO) and continuous positive airway pressure (CPAP) in hypoxic patients. Further studies are required to elucidate the challenging issues, thus enhancing the management of COVID-19 patients.
