Aim: Acute coronary syndromes (ACSs) are classified as ST-segment elevated myocardial infarction (STEMI), non-ST-segment elevated myocardial infarction (NSTEMI) and unstable angina pectoris (USAP). Cardiac troponins constitute the cornerstone biomarkers for the laboratory diagnosis of ACS. In this study, we aimed to investigate whether systemic immune-inflammation index (SII) is associated with peak cardiac troponin T (TnT) levels in ACS.Methods: Consecutive patients with ACS whose coronary angiography was performed were included in the present study (n=397). Admission SII was determined as platelet count x neutrophil count/lymphocyte count. Serum levels of cardiac enzymes, including high-sensitivity TnT and creatine kinase-myocardial band (CK-MB), were measured at the time of admission and repeated daily during patients’ hospital stay.Results: Patients were categorized as namely STEMI (n=92) and NSTEMI/USAP (n=141). The findings obtained in this study showed that the median of SII levels was higher in STEMI than NSTEMI/USAP at a significant level. Correlation analysis of SII with various clinical and laboratory parameters demonstrated a significant correlation with C-reactive protein, peak CK-MB (r=0.52, p

Aim: Methanol poisoning (MP) is an essential medical problem worldwide, and despite advances in diagnosis and treatment, the mortality rate in these cases is high. This study aimed to evaluate the clinical and laboratory factors to determine in-hospital mortality in patients with MP. Methods: This single-center, retrospective, observational study was conducted with adult 65 MP cases visiting the emergency department (ED) of a tertiary training and research hospital between January 01, 2017, and February 01, 2022. Data were statistically compared between survivors and non-survivors. Results: The in-hospital mortality rate was 41.5%. The rate of cases with respiratory distress, low Glasgow coma scale (GCS) (≤8), and delayed arrival to the hospital (>24 hours) was higher in the group of non-survivors compared to the group of survivors. Non-survivors had a higher anion gap (30.5 mEq/L vs. 25.5mEq/L), base excess (-25.0 mmol/L vs. -18.6 mmol/L), lactate (10.2 mmol/L vs. 2.2 mmol/L) levels, and lower pH (6.76 vs. 7.14) and bicarbonate (6.3 mmol/L vs. 10.3 mmol/L) levels than survivors (p
