Objective: Graft-versus-host disease (GvHD) is a common and serious complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), significantly impacting transplant efficacy. In the treatment of GvHD, numerous therapeutic approaches have been explored, with mesenchymal stem cells (MSCs) emerging as a prominent immunomodulatory option. We aimed to evaluate efficacy and outcomes of using MSCs for steroid refractory acute GVHD (SR-aGvHD) management.

Background And Objectives: Following an allogeneic hematopoietic stem cell transplant (allo-HSCT), a primary cause of morbidity and mortality is still steroid-refractory acute graft-versus-host disease (SR-aGVHD). Recently, ruxolitinib, an oral inhibitor of JAK1 and JAK2, was approved for use in individuals suffering from SR-aGVHD. This study aimed to analyze the efficacy and toxicity of ruxolitinib in the real world.

Objective: Vitamin D deficiency is common in adult patients undergoing allogenic hematopoietic stem cell transplantation (allo-HSCT). Since vitamin D is an important regulatory factor for the immune system, vitamin D deficiency may have effects on antitumor activity, relapse rates, graft versus host disease (GVHD) occurrence and infection rates in allo-HSCT. We aimed to investigate the effects of vitamin D levels on the outcome of allo-HSCT.

Objectives: In this study, we aimed to compare the engraftment days, graft versus host disease (GVHD) development, relapse and overall survival (OS) rates in patients using variable intensity conditioning regimens with two different post-transplant cyclophosphamide (PTCy) doses for hematological malignancies.

Material And Methods: We retrospectively analyzed 162 patients who have had PTCy at a dose of 25 mg/kg × 2 and 50 mg/kg × 2 between 2018 and 2024. Patients were divided in 2 groups; PTCy dose with 25 mg/kg × 2 (Group 1, n = 45) and PTCy dose with 50 mg/kg × 2 (Group 2, n = 117).

Background: Recent advances have increased the importance of the human microbiome, including the skin microbiome. Despite the hand microbiome research, the factors affecting the composition of the hand microbiome and their personal characteristics are incompletely known.

Objectives: Despite changing environmental factors and personal variation, we aimed to indicate the interpersonal distinction between skin microbiota using simple and rapid molecular methods.

Article Synopsis
  • Ovarian cancer (OC) has a high mortality rate, particularly in advanced stages, so understanding genetic factors is important for prevention and treatment; this study focuses on the roles of two DNA repair-related genes, XPC and DDB2, in OC susceptibility.
  • The study examined genetic variations in XPC rs2228001 and DDB2 rs830083 among 103 OC patients and 104 control subjects from Turkey, utilizing a PCR genotyping method.
  • Results indicated that certain genotypes of XPC and DDB2 are linked to either reduced or increased risk of developing OC, highlighting the significance of DNA repair systems in the disease and suggesting the need for more extensive research

Background/aim: Meningiomas are one of the most common intracranial tumors, accounting for 30% of the tumors of the central nervous system. MicroRNAs (miRNAs) are noncoding RNAs containing approximately 18-22 nucleotides that regulate gene expression by interfering with transcription or inhibiting translation. Recent studies have reported that miRNAs could provide information about the molecular pathogenesis of several types of tumors.

Objective: The discovery of imatinib was a milestone for chronic myeloid leukemia (CML). As the life expectancy of CML patients has approached that of the general population, research has shifted towards improving quality of life and economic considerations. After 2010, it was shown that some patients could maintain molecular response even after discontinuing imatinib.

Our aim was to determine the laboratory parameters that distinguish pseudothrombocytopenia from true thrombocytopenia. A total of 107 patients who were referred to the adult hematology outpatient clinic with thrombocytopenia and subsequently diagnosed with acute myeloid leukaemia, immune thrombocytopenia and pseudothrombocytopenia were included in our study. Hemogram parameters on admission, platelet value in the control hemogram and peripheral smear findings were recorded.

Objective: Panic disorder (PD) may cause serious cardiac arrhythmias by causing electrical abnormalities. Abnormal P-wave axis (aPwa), presence of fragmented QRS (fQRS), wide frontal QRS-T angle (fQRSTa), QRS duration corrected (QRSdc) and log/ logQRS duration/RR interval (log/logQRS/RR) have been correlated with increased risk of serious supraventricular and ventricular cardiac arrhythmias in a general population. The purpose of this study was to compare these newly explored atrial and ventricular arrhythmia indicators in patients with PD and in healthy subjects.

In this study, we measured the levels of depression and cognition in people recovering from COVID-19. Moreover, we aimed to investigate the relationship between depression and cognition levels by measuring homocysteine concentrations. It included 62 people recovering from COVID-19 (at least 3 months after positive RT-PCR) and 64 people without COVID-19 (control group).

Purpose: Monocyte/HDL cholesterol ratio (MHR) is a novel inflammatory marker that is used as a prognostic factor for cardiovascular diseases and has been studied in many diseases. The aim of this study was to investigate the role of inflammatory factors in schizophrenia patients by examining MHR levels and to compare schizophrenia patients and healthy controls in terms of cardiovascular disease risk.

Method: A total of 135 participants between the ages of 18-65, 85 diagnosed with schizophrenia, and 50 healthy individuals in the control group were included in this cross-sectional study.

Objectives: The relationship between ventricular arrhythmias and major depressive disorder (MDD) has been previously revealed. Recently, frontal QRS-T angle (fQRSTa) and Tp-Te/QT ratio proved to provide more accurate predictive data about ventricular arrhythmias than the measurement of QT, QTc, and QT dispersion. The aim of this study was to determine the effects of MDD on contemporary ventricular arrhythmia indicators.
