Aim: Atrial fibrillation (AF) is a rhythm disorder characterized by very rapid and disorganized atrial-derived electrical activations with uncoordinated atrial contractions. Very short periods of AF-like activity (micro-AF) may be precursors of undetected, silent episodes of atrial fibrillation. Here, we examined the relationship between natriuretic peptide concentrations and echocardiography findings in patients with micro-AF.

Article Synopsis
  • The study investigates the relationship between endocan levels and coronary artery disease (CAD) and coronary slow flow (CSF) in a group of 169 subjects undergoing coronary angiography.
  • Both CAD and CSF patients exhibited significantly higher endocan levels compared to a control group, with similar levels between the two conditions, suggesting endocan's role in these diseases.
  • Endocan levels, particularly when exceeding 450 pg/mL, are key predictors for both CAD and CSF, highlighting its potential as an important biomarker in these cardiovascular conditions.

Introduction: We compared the efficacy of first-generation granisetron and second-generation palonosetron in triplet anti-emetic prophylaxis in patients with non-small cell lung cancer (NSCLC) receiving cisplatin-based high emetogenic chemotherapy (HEC).

Methods: This prospective, multicenter, non-randomized, observational study was conducted between June 2018 and December 2021. Patients diagnosed with NSCLC who received triplet anti-emetic prophylactic treatment with aprepitant and dexamethasone plus granisetron or palonosetron before the first cycle of chemotherapy were included in the study.

Purpose: Vascular endothelial growth factor (VEGF) inhibition is one of the cornerstones of treatment in the treatment of metastatic renal cell carcinoma (mRCC). Since RCC is a disease of advanced age and hypertension as a side effect of VEGF receptor inhibitors, beta-blocker use is common in these patients. We aimed to compare the treatment efficacy and survival results in case of concomitant use of these two drugs due to the inhibition of VEGF in beta-blockers.

Objective: In our study, we aimed to find simple, useful biomarkers in patients with non-ST elevation myocardial infarction to predict coronary artery severity.

Methods: Between May 2022 and December 2022, patients diagnosed with non-ST elevation myocardial infarction according to the European cardiology guidelines were included in our study. The Synergy between PCI with Taxus and Cardiac Surgery score was calculated to determine the severity of coronary artery disease.

Purpose: The prognostic nutritional index (PNI), like other systemic inflammatory markers, has been shown to be a prognostic factor in various cancer patients. In this study, we aimed to show whether PNI calculated before adjuvant chemotherapy is a prognostic factor for overall survival (OS) and disease-free survival (DFS) in patients with lymph node-positive stage II-III gastric cancer.

Methods: The PNI was calculated using the albumin and lymphocyte count.

Aim: The aim of this study was to evaluate the presence of small bowel wall edema (SBWE) on computed tomography (CT) images in patients with metastatic renal cell carcinoma (mRCC) treated with sunitinib and to investigate the relationship between the presence of SBWE and survival.

Materials And Methods: We retrospectively evaluated the presence of SBWE on CT images of 27 mRCC patients who received at least one cycle of sunitinib. Then, we analyzed the relationship between the presence of SBWE and progression-free survival (PFS) and overall survival (OS).

Background: Coronary slow flow (CSF) refers to delayed distal vessel opacification in the absence of epicardial coronary artery stenosis. The etiopathogenic mechanism of CSF is still unclear.

Objectives: This study investigates the relationship between CSF and the triglyceride-glucose (TyG) index.

Aim: It is red cell distribution width (RDW) that has been reported to show an inflammatory response which has been studied recently. The aim of this study is to investigate whether the pre-treatment RDW in patients using first-line vascular endothelial growth factor tyrosine kinase inhibitor (VEGFR TKI) with the diagnosis of metastatic renal cell carcinoma (mRCC) predicts treatment response and is a prognostic factor or not.

Methods: About 92 patients diagnosed with mRCC who were being treated with sunitinib or pazopanib in the first line between January 2015 and June 2021 were included in the study.

Objective: In this article, we investigated the association of chromogranin A with coronary artery disease.

Methods: Biochemical parameters and chromogranin A levels obtained from peripheral blood samples during coronary angiography were analyzed in 90 patients. Patients were classified into two groups, namely, SYNergy between PCI with TAXUS and Cardiac Surgery score ≥1 (n=45) and SYNergy between PCI with TAXUS and Cardiac Surgery score=0 (n=45).

Objective: We designed a retrospective study to evaluate the performance and outcomes of a novel iopromide-based paclitaxel-coated balloon for the treatment of chronic total occlusion of femoropopliteal arteries.

Methods: Patients with femoropopliteal chronic total occlusion (<100 mm) on angiogram were screened from hospital management system and were included in the study. The width and length of the drug-eluting peripheral balloon was chosen to ensure a vessel/balloon ratio of 1: 1 and exceed the lesion by 10 mm on both ends (based on visual estimation).

Background: Not all RAS wild-type metastatic colorectal cancer (mCRC) patients experience the same benefit from anti-epidermal growth factor receptor (EGFR) treatments. Studies have shown that nuclear factor-κB (NF-κB), hypoxia-inducible factor-1α (HIF-1α), interleukin 8 (IL-8) and transforming growth factor β (TGF-β) may be therapeutic targets for mCRC. The aim of this study was to clarify the prognostic value of NF-κB, HIF-1α, IL-8, and TGF-β expression in patients with left-sided mCRC receiving EGFR inhibitors.

Aims: The addition of aflibercept to the fluorouracil and irinotecan (FOLFIRI) regimen significantly improved clinical outcomes in patients with metastatic colorectal cancer (CRC) previously treated with oxaliplatin. We aimed to investigate the efficacy and safety of second-line FOLFIRI and aflibercept combination in patients with metastatic CRC in real-life experience.

Materials And Methods: Four hundred and thirty-three patients who treated with FOLFIRI and aflibercept in the second-line were included in the study.

Objective: This study was an investigation of the role of left ventricular (LV) apical rotation seen in the early period after myocardial infarction (MI) in predicting infarct localization.

Methods: A total of 124 patients with a ST-Segment elevation myocardial infarction (STEMI) diagnosis who underwent primary percutaneous coronary intervention (PCI) and 50 healthy volunteers with similar demographic characteristics were included in the study.
