RESUMO
OBJECTIVE: No effective treatment has yet been found for SARS-Cov-2, which caused a pandemic outbreak in 2019. It is crucial to detect the progression of COVID-19 in patients as early as possible. Fibrinogen to albumin ratio (FAR) has been used as a new inflammatory marker. We aimed to find out whether the use of the FAR as a predictor of mortality in COVID-19 patients provides clinical benefit. MATERIALS AND METHODS: Data from 590 patients with COVID-19 from March 15, 2020 to January 15, 2021 in medicine wards and intensive care units (ICU) were retrospectively analysed. Demographic data and other laboratory markers were collected from the electronic medical records. Relationship between FAR was investigated between patients in the survivor/non-survivor patients. FINDINGS: The mean FAR levels in patients who were non-survivor was 24.44 ± 30.3 (n = 272 and 11.29 ± 6.29 (n = 275) (P = .000) in patients survivor COVID-19 infection. In ROC curve for FAR, the threshold FAR that may pose a risk for mortality was determined as 13.84 ((AUC: 0.808 (0.771-0.844)); 74.9% sensitivity, 74.6% specificity; P = .000)). RESULT: As a result of this study, increased FAR were found to be important markers in determining the mortality levels in COVID-19 patients.

BACKGROUND: Some biomarkers have been reported to be related to the prognosis of the coronavirus disease 2019 (COVID-19). There are sparse data regarding the prognostic value of serum calprotectin in COVID-19 patients. AIMS: This study aimed to investigate the relationship between serum calprotectin level and clinical severity of COVID-19 disease in hospitalized patients. METHODS: This retrospective cross-sectional cohort study included 80 consecutive hospitalized patients with confirmed diagnosis of COVID-19. The study population was divided into two groups as patients hospitalized in the intensive care unit (ICU) and patients hospitalized but not in the ICU. The serum calprotectin levels, other laboratory, and clinical parameters were compared between groups. RESULTS: The mean age of the patients was 66.5 ± 15.7 years. Of the patients, 42 were in the ICU and 38 were not. Serum calprotectin level and acute-phase reactants such as C-reactive protein, procalcitonin, ferritin, fibrinogen, and white blood cell were significantly higher in ICU patients than in non-ICU patients. ROC curve analysis identified that serum calprotectin level was a predictor for ICU requirement with an area under the curve of 0.641 (p = 0.031). Logistic regression analysis revealed that serum calprotectin was a significant determinant for whether or not patient required the ICU. CONCLUSIONS: These findings demonstrate that serum calprotectin level seems to be a useful biomarker that can predict the severity of COVID-19 disease. Serum calprotectin is a significant predictor of ICU requirement in patients with COVID-19.

INTRODUCTION: Introduction: some factors have been shown to be associated with survival in patients with pancreatic adenocarcinoma. Recently, some studies suggested that malnutrition, muscle mass, and inflammation might have an effect on survival in patients with pancreatic malignancy. Objectives: to investigate the association between psoas muscle mass, inflammation, nutritional status at the time of diagnosis, and survival in patients with pancreatic adenocarcinoma. Methods: this retrospective study included 219 patients diagnosed with pancreatic carcinoma. The nutritional status, inflammation, and psoas muscle mass of the patients at the time of diagnosis were evaluated. Nutritional status was assessed using the Prognostic Nutritional Index (PNI). Leucocyte count and neutrophil/lymphocyte ratio (NLR) were used for inflammation assessment. Psoas muscle mass was calculated by using abdominal computed tomography images of the patients. Results: the mean age of patients (80 female and 139 male) was 66.6 ± 11.7 years. According to the PNI results, 155 patients had a normal nutritional status (70 %), whereas 64 patients were malnourished (30 %). The survival of the patients with normal nutritional status was significantly longer than that of those who were malnourished (p < 0.001). There was no significant relationship between psoas muscle area, leucocyte count, NLR, and survival time. Conclusion: the survival of pancreatic adenocarcinoma patients with malnutrition at the time of diagnosis was significantly shorter than for patients without malnutrition.
INTRODUCCIÓN: Introducción: se ha demostrado que algunos factores se asocian a la supervivencia en los pacientes con adenocarcinoma de páncreas. Recientemente, algunos estudios sugirieron que la desnutrición, la masa muscular y la inflamación podrían afectar a la supervivencia de los pacientes con neoplasias malignas pancreáticas. Objetivo: investigar la asociación entre masa muscular del psoas, inflamación, estado nutricional en el momento del diagnóstico y supervivencia en pacientes con adenocarcinoma de páncreas. Métodos: este estudio retrospectivo incluyó a 219 pacientes diagnosticados de carcinoma de páncreas. Se evaluaron el estado nutricional, la inflamación y la masa del músculo psoas de los pacientes en el momento del diagnóstico. El estado nutricional de los pacientes se evaluó con el Índice Nutricional Pronóstico (PNI). El recuento de leucocitos y el cociente de neutrófilos/linfocitos (NLR) se emplearon para la evaluación de la inflamación. La masa del músculo psoas se calculó utilizando las imágenes de tomografía computarizada abdominal de los pacientes. Resultados: la edad media de los pacientes (80 mujeres y 139 hombres) fue de 66,6 ± 11,7 años. Según los resultados del PNI, 155 pacientes tenían un estado nutricional normal (70 %) mientras que 64 pacientes estaban desnutridos (30 %). La supervivencia de los pacientes con estado nutricional normal fue significativamente mayor que la de los pacientes desnutridos (p < 0,001). No hubo ninguna relación significativa entre el área del músculo psoas, el recuento de leucocitos, el NLR y el tiempo de supervivencia. Conclusión: la supervivencia de los pacientes con adenocarcinoma de páncreas con desnutrición en el momento del diagnóstico fue significativamente menor que la de los pacientes sin desnutrición.

OBJECTIVE: To analyse whether prealbumin could be a new biomarker for predicting mortality in severe COVID-19 patients. STUDY DESIGN: An observation study. PLACE AND DURATION OF STUDY: Intensive care units (ICU) of Sakarya University Training and Research Hospital, Sakarya, Turkey, from October 2020 to December 2020. METHODOLOGY: The data of 149 patients, who were admitted to the ICU were collected and analysed retrospectively. Routine blood samples were collected from all patients at the time of admission to the ICU; and 102 patients with the mortal course and 47 patients with the non-mortal course were included in the study. The data obtained from these patients were analyzed in the biostatistics programme. Results: The median age of all patients was 68 years; while 94 of them were males (63.1%) and 55 of them were females (36.9%). Median levels of potassium (K) (p=0.04), uric acid (p=0.001), C-reactive protein (CRP) (p=0.004), and procalcitonin (PCT) (p<0.001) were significantly higher and median level of prealbumin (p=0.002) was significantly lower in the deceased group. The cut-off level of prealbumin for mortality was found as 0.085 g/L (p=0.002). Further analysis revealed that the risk of mortality was found as 2.193 times more in patients with prealbumin levels of <0.085 g/L (Odds Ratio (OR): 2.193, 95% CI: 1.084-4.434). CONCLUSION: As a result of this study, it was found that patients with lower levels of prealbumin at the time of admission to the ICU have a higher risk for mortality. It was showed that prealbumin can be a useful biomarker for predicting mortality in patients with severe COVID-19. Key Words: Prealbumin, COVID-19, Mortality, Prognostic biomarkers, Severe disease.

OBJECTIVE: The present study compares the cardiac parameters of the survivor and nonsurvivor patients with COVID-19 infection. METHODS: This study was conducted in 379 patients diagnosed with COVID-19 disease. Information of 21 nonsurvivor and 358 survivor patients with COVID-19 was obtained from the hospital information management system and analyzed retrospectively. Relationship between cardiac parameters in patients categorized into the mortal and immortal groups was investigated. RESULTS: Of the total 379 patients involved in this study, 155 (40.9%) were females and 224 (59.1%) were males. No statistically significant difference in mortality was found between females and males (p=0.249). The total median age was 70, the median age in the nonsurvivor group was 74 (35-89), and it was 69.5 (18-96) in the survivor group (p=0.249). The median values of high-sensitivity troponin (hs-Tn), creatine kinase MB form, and especially myoglobin in the survivor and nonsurvivor groups were 25/64.9 (p=0.028), 18/23 (p=0.02), and 105.5/322.4 (p<0.001), and the difference was statistically significant. Comparing mortality, while there was 1 (0.7%) nonsurvivor out of 134 patients in the service unit, there were 20 (8.2%) nonsurvivors out of 245 patients in the intensive care unit. This difference was statistically significant (p=0.003). The cutoff value of myoglobin, which may pose a risk of mortality, was found to be 191.4 µg/L, while it was 45.7 ng/l for hs-Tn and 60.1 U/L for creatine kinase MB. CONCLUSIONS: Advanced age and increased levels of high-sensitivity troponin, creatine kinase MB, and myoglobin were found to be associated with mortality.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an acute inflammatory respiratory disease. Osteopontin (OPN) is a glycoprotein expressed in various cell types, such as bone, immune, smooth muscle, epithelial and endothelial cells. It also acts as a regulator of immune response. The aim of the present study was to reveal the place of serum osteopontin levels in predicting severity among patients with COVID-19. METHODS: This study included 84 patients, 43 female and 45 male. Patients were divided into 2 groups, group 1 non-severe group (n: 48), group 2 severe (n: 40). Demographic data, neutrophil, lymphocyte, platelet, white blood cell counts, albumin, procalcitonin, Creactive protein (CRP) and OPN levels were recorded. The OPN levels and these inflammatory parameters of the two groups were compared. RESULTS: There were no significant differences in terms of gender (female/male 25/23 vs. 18/22) and platelet count (178â¯K/µL vs. 191â¯K/µL) between the groups (pâ¯> 0.05). Ages (57.7⯱ 17.0 years vs. 71.4⯱ 12.8 years), procalcitonin (0.07 vs. 0.24â¯ng/mL), CRP (17 vs 158â¯mg/l), neutrophil count (3.7 vs 5.64â¯K/µL), WBC counts (5.38 vs 7.85â¯K/µL) and number of deaths (0 vs 26) (pâ¯< 0.001). The OPN levels (98.5 vs 13.75â¯ng/mL, pâ¯= 0.002) were found to be statistically higher, in group 2 than group 1. CONCLUSION: The present study showed that OPN can be used to predict the severity in patients with COVID-19.
