ABSTRACT
Aim: The aim of this study is to analyze the effectiveness of the leukocyte albumin ratio (LAR) in predicting mortality in critical COVID-19 patients. Material(s) and Method(s): In this retrospectively-designed study, we evaluated a total of 98 critical patients who were hospitalized in the intensive care unit. Patients were divided into two groups according to hospital mortality as survivors (n=43) and non-survivors (n=55). Result(s): The non-survivors group was statistically significantly older (67.3+/-9.7 versus 62.5+/-10.9;p=0.023). HT and DM were detected more in the non-survivors group than in the survivors group (p=0.031, p=0.018, respectively). Mean LAR values were significantly higher in non-survivors than in survivors (5.9+/-3.5 versus 3.3+/-1.4;p<0.001). LAR values was positively correlated with urea (r=0.43, p<0.001), LDH (r=0.35, p<0.001), ferritin (r=0.25, p=0.015), procalcitonin (r=0.34, p<0.001), and pro-BNP (r=0.24, p=0.015) levels. A cut-off value of 3.71 ng/mL for LAR predicted mortality with a sensitivity of 76% and a specificity of 70% (AUC:0.779 95% Cl:0.689-0.870;p<0.001). Multivariable logistic regression analysis revealed that older age (OR:1.114, 95% CI:1.020-1.218;p=0.017) and increased ferritin (OR:1.003, 95% CI:1.001-1.004;p=0.002) and LAR (OR:1.583, 95% CI:1.073-2.337;p=0.021) values were independent predictors of mortality in patients with critical COVID-19. Discussion(s): LAR can be a useful and prognostic marker that can be used to predict mortality in COVID-19 patients admitted to the intensive care unit.Copyright © 2022, Derman Medical Publishing.

ABSTRACT
In this study, it was aimed to evaluate the relationship between the clinical course of the disease and hematological data, serum 25-hydroxyvitamin D (25 (OH) D), iron (Fe), free iron-binding capacity (UIBC), and D-dimer levels in calves with diarrhea in the neonatal period. Within the scope of the study, 10 healthy calves (group-I) and 30 diarrheal calves in the neonatal period of different races, ages and genders were used. Calves with diarrhea were divided into mild (group-II, n=10), moderate (group-III, n=10) and severe (group-IV, n=10) groups. Blood samples were taken from calves in all groups at once. Hematological analyzes were performed using a veterinary-specific hematology analyzer device. In serum samples, 25 (OH) D3, Fe and UIBC levels were determined with an autoanalyzer, and D-dimer levels were determined with an automatic immunoassay analyzer. In the hematological analysis, an increase was observed in the number of LYMs (lymphocytes) in group-II (5.04±1.3) and III (5.2±3.3) compared to group-I (4.47±1.2), and a decrease was observed in group IV (2.76±0.9) (P<0.05). Fe levels in group-II (59±56), group III (56±52) and group IV (72±63) were found to be decreased compared to group-I (131±66) (P<0.05). It was determined that the 25 (OH) D3 level of group IV (13.4±8.5) was higher than that of group-I (6.12±2.73) (P<0.05). D-dimer levels of group-III (1.15±1.13) and group-IV (0.96±0.88) were found to be higher than group-I (0.10±1.46) (P<0.05).
