BACKGROUND AND OBJECTIVES: Treosulfan is a prodrug applied in the treatment of ovarian cancer and conditioning prior to stem cell transplantation. So far, the bioanalysis of treosulfan in either whole blood or red blood cells (RBC) has not been carried out. In this work, the RBC/plasma partition coefficient (Ke/p ) of treosulfan and its active monoepoxide was determined for the first time. METHODS: Male and female 10-week-old Wistar rats (n = 6/6) received an intraperitoneal injection of treosulfan at the dose of 500 mg/kg body weight...

Introduction We investigated the association of the neutrophil/lymphocyte ratio (NLR) with tumor size and Fuhrman grade in nonmetastatic renal cell carcinoma (RCC) cases. Materials and methods Data of nonmetastatic RCC (T1-4N0M0) cases, operated between 2010 and 2016, were retrospectively reviewed and 103 patients were included in the study. The patients were divided into two groups according to tumor diameter (Group 1 T < 4 cm, Group 2 T ≥ 4 cm) and into three groups according to Fuhrman grade. Twenty-eight patients with a tumor diameter of 4 cm or less in Group 1 and 75 patients with a tumor diameter greater than 4 cm in Group 2 were compared...

We aimed to investigate the relationship between the histologic severity and red blood cell distribution width to platelet ratio (RPR) in patients with primary biliary cholangitis (PBC). One hundred and seven consecutive patients with liver biopsy-proven and as yet treatment-naïve PBC were enrolled as the primary and validation cohort. The histologic stages were divided into early stage (Scheuer's stage 1 & 2) and late stage (Scheuer's stage 3 & 4). The overall patient demographics, clinical manifestations, hematological tests and biochemical profile were retrospectively collected from our database...

Objective: Tonsillectomy is one of the most common surgical procedures performed at ear, nose, and throat clinics. Chronic recurrent tonsillitis, obstructive tonsillitis, and halitosis are among the most common indications for surgery. Determining whether the infection is chronic and the patient's annual number of infections are important in estimating the necessity for surgery to be performed due to infectious causes. Red blood cell distribution width (RDW) is a numerical value present in normal complete blood count that provides information about erythrocytes and their dimensions...

Legionella pneumophila causes water-based infections resulting in severe pneumonia. Recently, we showed that different variable numbers of tandem repeat analysis (MLVA-8) genotypes dominated different sites of a drinking-water distribution system, with a genotype-related temperature and abundance regime. Here we compare the pathogenicity potential of different MLVA-8 genotypes of environmental and clinical strains. The virulence traits studied were hemolytic activity and cytotoxicity towards amoebae and macrophages...

CONTEXT AND OBJECTIVE: Microcytic anaemia results from defective synthesis of haemoglobin in the erythroid precursors, causing a reduction in its mean corpuscular volume (MCV). The most common causes of microcytosis, without the increase in HbA2 levels, are iron deficiency anaemia (IDA) and α-thalassemia. The aim of this study was to identify the causes of microcytic anaemia and evaluate the haematological parameters from blood donors deemed ineligible (due to the low haematocrit level) that would differentiate the IDA and α-thal, whether isolated or in association...

Inertial and deformability- based particles separations gradually attract more significant attentions. In this work, we present a hybrid chip by combining the advantages of inertial and deformability -based principle. The chip is a triplet parallelizing spiral inertial microfluidic chip interconnected with numerable tilted slits (Spiral-Slits Chip) for continuous separation of circulating tumor cells. Utilizing the inertial lift and viscous drag forces, different sized particles achieve different equilibrium at distinct streamlines of the spiral microchannel...

This thesis is comprised of three studies focusing on severe postpartum haemorrhage (PPH). PPH is a major cause of maternal morbidity and mortality worldwide. Risk factors include retained placenta, prolonged duration of the third stage of labour, previous caesarean section, and operative vaginal delivery. Occurrence and development of PPH are, however, unpredictable and can sometimes give rise to massive haemorrhage or even hysterectomy and maternal death. Severe haemorrhage can lead to coagulopathy causing further haemorrhage and requiring substitution with blood transfusions...

INTRODUCTION: Cardiovascular diseases constitute a major cause of health problems and death in developed countries across the world. The increased value of the index of distribution of red blood cells volume (RDW) may be a prognostic marker in patients diagnosed with chronic heart failure (CHF). Hypothyroid patients present higher RDW values if compared to healthy controls. Taking into consideration that RDW might be both affected by thyroid status and CHF, we decided to determine the effect of concomitant hypothyroidism following radioiodine therapy (RIT) and CHF on hematological parameters...

BACKGROUND: Acute exacerbation of COPD (AECOPD) is one of the leading causes for hospitalization and readmission in developed countries. No laboratory indices were consistently found to be associated with readmission risk. Recent evidence attests that red blood cell distribution width (RDW), conveys important information for short and long term prognosis in a variety of medical conditions. Prognostic usefulness of RDW in patients with AECOPD has not been investigated. OBJECTIVE: To evaluate the usefulness of RDW in predicting early adverse outcomes in patients hospitalized due to AECOPD...

Background: The red cell distribution width (RDW) has been shown to be associated with the incidence and complications of type 2 diabetes (T2D). However, the relevance of RDW with the risk of being in poor glycemic control among patients with established T2D is largely overlooked. Methods: A total of 702 T2D participants from the REACTION study were enrolled in this study. Blood routine index, fasting plasma glucose, hemoglobin A1c and lipid profile data were available for all of the enrolled population...
