Aim: We aimed to determine the frequency of troponin elevations in COVID-19 patients and to investigate the role of troponin in demonstrating the prognosis of COVID-19 by examining the clinical course of theese patients. Material and Method: Patients diagnosed with COVID-19 disease were included in the study. Patient files were analyzed retrospectively through the hospital information management system.Patients with high troponin levels were identified and comparisons were made with patients with normal troponin levels. Results: 1468 patients were included in the study.Troponin level was found to be high in 6.7% of the patients.The presence of pneumonia on thorax CT rate,hospitalization rate,ICU admission rate,intubation rate was significantly higher in patients with high troponin levels.The mortality rate was 2.1% in the whole group.The mortality rate was significantly higher in the patients with high troponin levels.Total length of hospital and ICU stay were significantly higher in patients with high troponin levels.There was a significant positive correlation between the troponin levels of the patients at admission and the total length of hospital stay and length of ICU stay. 49.5% of COVID-19 patients had another comorbid disease.Hypertension was the most common comorbid disease. The rate of troponin elevation and troponin levels were significantly higher in patients with other comorbid diseases. Conclusion: It has been found that high troponin levels in COVID-19 patients may be associated with a poor clinical prognosis. Troponin can be used as a predictor of prognosis with more comprehensive studies and long-term follw-up results in the future.

Introduction: To date, the world has experienced four waves of the Coronavirus disease- 19 (COVID-19) pandemic. Patients infected during the era of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant were the subject of this study. The objectives were to describe their clinical manifestations, explain their laboratory and radiological findings, conclude factors contributing to clinical outcomes, and evaluate treatment protocols. Methodology: Relevant data were collected retrospectively from records of patients admitted to six referral centers in four countries. Data included sociodemographic patterns, symptoms, associated comorbidities, physical examination, laboratory and radiologic findings, treatment received, and patient outcomes. Results: Data analysis identified symptomatology and variables related to acquisition and infection outcome. The most prevalent symptoms were cough (81.5%), body aches (74.1%), and fever (71.6%). Independent risk factors for mortality were age, vomiting, epigastric pain, diabetes, obesity, oxygen saturation less than 90%, leukocytosis, neutrophilia, lymphopenia, thrombocytopenia, elevated creatinine, high glucose level, lung ground glass opacities with consolidation, affection of four lobes and bilateralism. Neither d-dimer nor lactate dehydrogenase nor ferritin foretells death possibility. The efficacy of the medications used was convenient. Conclusions: Assessing the clinical features of different COVID-19 waves, identifying predictors of outcomes, and concluding the efficacy of treatment protocols provide insight into patients’ responses and viral behaviors, which help in the proper diagnosis and treatment of subsequent surges.

Aim: It was aimed to investigate the relationship between the prognostic nutritional index (PNI) and the clinical course in COVID-19 because the nutritional status is important in defense against infection. Material and Method: 1579 patients who applied to the hospital inpatient clinic between 01/04/2020 and 30/11/2020 were included in the study. The PNI scores of the patients were calculated at the time of admission to the hospital. Comparisons were made between PNI scores of the patients and intensive care unit admission status, treatment results, length of hospital stay, and presence of pneumonia on thorax CT. Moreover, comparisons were made between PNI scores and C-reactive protein (CRP), neutrophil/ymphocyte ratio (NLR), CRP/albumin ratio. Results: A total of 1579 patients (755 females and 824 males) were included in the study. The rate of admission to the ICU was significantly higher in males. The mortality rate of the study group was 9.4%. PNI scores were found to be significantly lower in patients who died and in patients admitted to the ICU. CRP and CRP/albumin ratio levels were significantly higher in patients with pneumonia on thorax CT, in patients admitted to the intensive care unit, and in patients who died. There were a significant negative correlation between PNI score and CRP/albumin ratio levels. Conclusion: PNI scores were found to be significantly lower in patients who needed admission to the intensive care unit and died due to severe COVID-19 than the others. In patients with a low PNI score, COVID-19 can be more severe and it may cause worse clinical outcomes.

This study aimed to evaluate the effects of sodium-glucose cotransporter-2 inhibitors on nutritional status in patients with heart failure with reduced ejection fraction. The sodium-glucose cotransporter-2 inhibitor treatment was initiated in 153 patients with heart failure with reduced ejection fraction who were symptomatic despite optimal medical treatment and were followed up for 6 months. The Minnesota Living With Heart Failure Questionnaire scores, New York Heart Association functional class, NT-pro-BNP levels, and nutritional index scores of the patients were evaluated before sodium-glucose cotransporter-2 inhibitor treatment and at the 6-month follow-up. The nutritional status of the patients was evaluated with the COntrolling NUTritional Status score, Geriatric Nutritional Risk Index, and Prognostic Nutritional Index. After sodium-glucose cotransporter-2 inhibitor treatment, significant changes were observed in the mean scores of the three different nutritional indexes: COntrolling NUTritional Status (before: 2.76±2.43 vs. after: 1.12±1.23, p<0.001), Geriatric Nutritional Risk Index (before: 98.2±9.63 vs. after: 104.4±5.83, p<0.001), and Prognostic Nutritional Index (before: 37.9±4.63 vs. after: 42.9±3.83, p<0.001) scores. A significant decrease in the number of patients with malnutrition was observed according to the COntrolling NUTritional Status (before: 46.4% vs. after: 9.7%, p<0.001), Geriatric Nutritional Risk Index (before: 41.8% vs. after: 18.9%, p=0.006), and Prognostic Nutritional Index (before: 36.6% vs. after: 13.7%, p=0.007) scores. A significant functional improvement was observed in patients after sodium-glucose cotransporter-2 treatment: Minnesota Living With Heart Failure Questionnaire scores (before: 39.2±7.2 vs. after: 20.4±7.4, p<0.001), NT-pro-BNP levels (before: 2989±681 vs. after: 1236±760, p<0.001), and New York Heart Association class (before: class II-III: 95.5%; class IV: 4.5% vs. after: class II-III: 78%; class IV: 0%, p<0.001). In patients with heart failure with reduced ejection fraction who are symptomatic despite optimal medical treatment, the addition of an sodium-glucose cotransporter-2 inhibitor to treatment can significantly improve both the nutritional and functional statuses.

The objective is to investigate the potential adverse effects of iron deficiency and iron deficiency anemia on renal functions by utilizing plasma Neutrophil Gelatinase-Associated Lipocalin (NGAL) levels. From September 2021 to February 2022, plasma NGAL levels, hemogram, biochemical parameters were assessed in all participants. They were divided into three groups: Group I (non-anemic iron deficiency), Group II (iron deficiency anemia), and Group III (healthy controls), with comparative analyses conducted. Group I had 38 individuals, Group II had 75 individuals, and Group III included 57 individuals. Plasma NGAL levels were higher in Groups I and II compared to Group III, with no significant difference between Groups I and II. ROC analysis revealed an AUC of 0.63 for NGAL in distinguishing Group II from Group III. No significant disparities were found in serum creatinine and glomerular filtration rate levels among the groups. A significant negative correlation was observed between plasma NGAL levels and ferritin, iron, hemoglobin, and mean corpuscular volume (MCV) levels. Plasma NGAL levels were significantly higher in adult patients with non-anemic iron deficiency and iron deficiency anemia compared to the healthy group. This suggests that elevated plasma NGAL levels in these patients might indicate renal injury due to various mechanisms.
