Association between atherogenic index of plasma and in-hospital mortality in patient with STEMI undergoing primer PCI

Aim: Dyslipidemia is an established risk factors for cardiovascular disease. Increased triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) levels, and decreased HDL-C levels were associated with increased cardiovascular risk. Recently, comprehensive lipid profile indices derived from these conventional parameters have attracted to attention. Atherogenic index of plasma (AIP) is one of the indices calculated as the logarithm of TG/HDL-C levels and, it is accepted as an alternative and simple marker of plasma atherogenicity. Although various studies demonstrated that their relationship with these lipid indices and clinical outcomes in patients with acute coronary syndrome, this situation is not yet clear in acute ST-elevation myocardial infarction (STEMI) patients undergoing primer percutaneous coronary intervention (pPCI). The aim of this study was to focus on the relationship traditional lipid levels and non-traditional comprehensive lipid indices and in hospital-mortality in patients with STEMI after pPCI. In this study, it is planned to investigate the relationship of AIP with early mortality in STEMI patients undergoing primary percutaneous coronary intervention. Material and Methods: In this retrospective, single center, hospital-based study, between January 2019 and April 2021, a total of 873 consecutive STEMI patients (705 men; median age 59 years), whose undergoing pPCI, are enrolled. The patients were divided into two groups according to in-hospital mortality status namely survivor and deceased. Conventional lipid values were measured and non-traditional lipid indexes including non-HDL-C [Total cholesterol minus HDL-C], Total cholesterol/HDL-C, LDL-C/HDL-C, atherogenic index (AI) [non-HDL-C/HDL-C], lipoprotein combine index (LCI) [Total cholesterol*TG*LDL-C/HDL-C] and atherogenic index of plasma (AIP) [Log(TG/HDL-C)] were calculated. Angiographic evaluations of the patients were performed through the hospital automation system. Results: AIP was significantly higher in hospital mortality patients compared to survivor group (0.59, 0.47, p=0.006, respectively). AI, non-HDL-C, Total cholesterol/HDL-C ratio, LDL-C/HDL-C ratio and LCI measurements were similar between two groups. The cut-off value of the AIP (0.50) was associated with 70% sensitivity and 52% specificity for predicts in-hospital mortality. Multivariate logistic regression model yielded AIP (OR: 3.77, 95% CI: 1.34–10.6, p < 0.012) as independent predictor of in-hospital mortality. Conclusion: AIP predicts in-hospital mortality in patients with STEMI undergoing pPCI. AIP, which can be calculated easily from complete blood, can be beneficial in the prognostication of these patients.

Risk factors associated with mortality in patients with methanol poisoning: a retrospective study

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

Anaplastik tiroid kanseri hücre hattının morfolojik analizi

Aim: Thyroid follicular cell derived cancers are classified into three groups such as papillary thyroid cancer (85%), follicular thyroid cancer (12%) and anaplastic (undifferentiated) thyroid cancer (ATC) (3%). ATCs have very rapid course, poor treatment outcomes and they are very aggressive. The aim of current study was to assess the analysis of the morphological differences of ATC cell line with the normal thyroid cell line (NTC). Materials and Methods: NTH and ATC cells were examined with haematoxylin and eosin, the nucleus: cytoplasm (N:C) ratios were detected, and cell cycles were investigated. These cell lines were compared according to their N:C ratio and their abundance in cell cycle phases. Results: The N:C ratio was higher in ATC than NTC. Both cell groups were mostly found in G0/G1 phase (68.4; 82.8) and have statistical difference in both G0/G1 and S phases. Conclusion: The rapid course and the rarity of ATC are significant barriers for clinical trials. Cultured cell lines are very important to explore the behaviour in the biology of ATC cells (such as the cell cycle), to understand the course of the disease, and to find an effective target for treatment.

Therapeutic plasma exchange in hypertriglyceridemic patients

Background/aim

High triglyceride (TG) levels are associated with increases in atherosclerotic cardiovascular disease (CVD), hepatic steatosis, and pancreatitis. Acute pancreatitis is a condition with high mortality. Therapeutic plasma exchange (TPE) in the treatment of hypertriglyceridemic pancreatitis (HTGP) is a rapid and effective treatment modality. In this study, the results of TPE were evaluated and the frequency of lipoprotein lipase (LPL) mutation in these patients was determined.

Materials and methods

TPE was performed in 31 patients with HTGP at the Adult Therapeutic Apheresis Center.

Results

A TG level under 500 mg/dL was achieved by applying apheresis at a median of 2 times (IQR 2–2, min 1, max 6) in the 31 cases. LPL mutation was detected in 8 (25.8%) of the 31 hypertriglyceridemia cases. When TG levels before and after TPE were evaluated, the mean TG level before TPE was significantly higher (3132 ± 1472 mg/dL) than the mean TG level afterwards (948 ± 465 mg/dL, P < 0.001). This result represented a decrease of 69.7% TG after TPE.

Conclusion

TPE is a safe, fast, and effective treatment modality in experienced centers.
