ABSTRACT
Coronavirus disease 2019 (COVID-19) is a rapidly spreading deadly respiratory disease that emerged in the city of Wuhan in December 2019. As a result of its rapid and widespread transmission, the WHO declared a pandemic on March 11, 2020 and studies evaluating mortality and prognosis in COVID-19 gained importance. The aim of this study was to determine the factors affecting the survival of COVID-19 patients followed up in a tertiary intensive care unit (ICU) and undergoing chest computed tomography (CT) scoring. This retrospective cross-sectional study was conducted with the approval of Usak University Medical Faculty Ethics Committee between July and September 2020. It included 187 symptomatic patients (67 females, 120 males) with suspected COVID-19 who underwent chest CT scans in the ICU. Demographics, acute physiology and chronic health evaluation (APACHE II), chest CT scores, COVID-19 real-time polymerase chain reaction (RT PCR) results, and laboratory parameters were recorded. SPSS 15.0 for Windows was used for the data analysis. The ages of the patients ranged from 18 to 94 and the mean age was 68.0â ±â 13.9 years. The COVID-19 RT PCR test was positive in 86 (46.0%) patients and 110 patients (58.8%) died during the follow-up. ICU stay (Pâ =â .024) and total invasive mechanical ventilation time (Pâ <â .001) were longer and blood urea nitrogen (BUN) was higher (Pâ <â .001) in the nonsurvivors. Patients with an APACHE II score of 23 and above had a 1.12-fold higher mortality rate (95% CI 0.061-0.263). There was no significant difference in total chest CT score between the survivors and nonsurvivors (Pâ =â .210). Chest CT score was not significantly associated with mortality in COVID-19 patients. Our idea that COVID-19 will cause greater mortality in patients with severe chest CT findings has changed. More studies on COVID-19 are needed to reveal the markers that affect prognosis and mortality in this period when new variants are affecting the world.

BACKGROUND: To investigate the levels of neutrophil-to-lymphocyte (NLR) and platelet-to-lymphocyte (PLR) ratios in those having a pulmonary embolism (PE) in the course of coronavirus disease 2019 (COVID-19). METHODS: The records of those having COVID-19 were retrospectively obtained from the hospital automation system. NLR and PLR were measured with the help of patients' blood cell counts. RESULTS: Of 1,452 COVID-19 patients, 17 (1.2%) were diagnosed with PE. Compared with the controls, while leukocyte (p = 0.001), neutrophil (p <0.001), and neutrophil percentages, (p = 0.001) and NLR (p <0.001) and PLR (p = 0.006) had higher values, lymphocyte count (p = 0.004) and lymphocyte percentage (p <0.001) showed lower values in the patients with PE.Compared to the survivors, the non-survivors were found to have increased leukocyte (p <0.001), neutrophil (p <0.001), and neutrophil percentages (p <0.001), NLR (p <0.001) and PLR (p <0.001), and decreased lymphocyte (p <0.001) counts and percentage (p <0.001), hemoglobin (p = 0.005), hematocrit (p = 0.012), and platelet counts (p <0.001).While NLR and PLR cutoffs were found as 4.338 and 187.83 in predicting PE, the cutoff values of NLR and PLR were, respectively, 4.301 and 172.5 in predicting mortality.The logistic regression analysis also revealed that all hematological parameters had no effects on the development of PE. CONCLUSION: Although NLR and PLR had higher scores in PE patients, no relationship was determined between the levels of NLR and PLR and PE development. Further prospective studies including larger populations are required to enlighten the increased NLR and PLR in PE patients having COVID-19.

ABSTRACT
Hashimoto's Thyroiditis (HsT) is one of the most frequently occurring autoimmune diseases, characterized by lymphocytic infiltration, destruction and fibrosis of thyroid tissue and the presence of antibodies to thyroid peroxidase and thyroglobulin. The effects of euthyroid Hashimoto's thyroiditis (eHsT) on cardiovascular system are unclear. We aimed to identify if any deteriorations in LA and LV myocardial functions in patients with eHsT by 3D-STE in the current study. Fifty eight patients with eHsT and 60 age- and gender-matched controls were enrolled into the study. All participants underwent laboratory analyses which included thyroid hormones and thyroid autoantibody levels; and conventional 2D echocardiographic and 3D-STE analyses were performed. The mean age of the study patients was 34.5 ± 9 years, and 68.6% were female. Left ventricular global longitudinal strain (LV-GLS) was significantly depressed in the eHsT (+) group than in the control group (- 15.3 ± 3.6 vs. - 22.8 ± 3.8, p < 0.001). The LV-GLS was found to be disrupted linearly as thyroid autoantibodies increased (r = 0.684 for anti-TPO-ab and LV-GLS; r = 0.649 for anti-Tg-ab and LV-GLS). The present study demonstrated that 3D-STE is useful in the early detection of LV myocardial dysfunction in patients with eHsT. We found that eHsT had a negative effect on LV myocardial dynamics. According to these findings, these myocardial alterations that are present early in the disease process may be considered as a reason to start medical treatment earlier, even at the euthyroid stage to prevent LV myocardial impairment.
