PURPOSE: Seasonal allergic conjunctivitis (SAC) is an inflammatory disease of the conjunctiva. Red cell distribution width (RDW) is a widely accepted inflammatory marker. We aimed to investigate whether RDW level is associated with the development of SAC in pediatric population. METHODS: The present study consisted of 90 subjects (45 children with SAC and 45 age- and sex-matched healthy children). The demographic findings, complete blood count parameters including RDW and laboratory parameters, were evaluated...

BACKGROUND: The prognostic impact of red blood cell distribution width (RDW) on adverse outcomes in patients with heart failure with preserved ejection fraction (HFpEF) is unclear. We investigated the association between RDW values at admission and long-term prognosis in patients with acute decompensated HFpEF. METHODS: The present study enrolled 278 consecutive patients with acute decompensated HFpEF, whose RDW levels were measured at admission. We divided enrolled patients into 2 groups according to RDW value and investigated the association between RDW and patients' mortality...

BACKGROUND: Iron is an essential element of most living organisms but is a dangerous substance when poorly liganded in solution. The hormone hepcidin regulates the export of iron from tissues to the plasma contributing to iron homeostasis and also restricting its availability to infectious agents. Disruption of iron regulation in mammals leads to disorders such as anemia and hemochromatosis, and contributes to the etiology of several other diseases such as cancer and neurodegenerative diseases...

Daidzein has become increasingly popular as a dietary supplement, particularly for postpeak-estrus animals, as a safe and natural alternative estrogen-like compound. However, there is little available safety data of daidzein in laying hens. A study was conducted to examine if high-dose daidzein affected the safety of hens, including mortality, laying performance, egg quality, hematological parameters, clinical chemical parameters, organ development parameters, and hatchability. A total of 2,448 42-wk-old Rugao laying hens were randomly assigned to 4 groups with 6 replicates of 102 birds each (612 laying hens per group)...

The mouse footpad for its feature of hairlessness provides an available window for imaging vascular and cellular structure and function in vivo. Unfortunately, the strong scattering of its skin limits the penetration of light and reduces the imaging contrast and depth. Herein, an innovative footpad skin optical clearing agent (FSOCA) was developed to make the footpad skin transparent quickly by topical application. The results demonstrate that FSOCA treatment not only allowed the cutaneous blood vessels and blood flow distribution to be monitored by laser speckle contrast imaging technique with higher contrast, but also permitted the fluorescent cells to be imaged by laser scanning confocal microscopy with higher fluorescence signal intensity and larger imaging depth...

BACKGROUND: Some studies showed that the value of red blood cell distribution width (RDW) at admission may predict clinical outcomes in patients with acutely decompensated heart failure (ADHF). Therefore, this study was planned to investigate whether in-hospital variations of RDW may also predict mortality in this condition. METHODS: The final study population consisted of 588 patients admitted to the local Emergency Department (ED), who were hospitalized for ADHF...

Red blood cell aggregation plays a key role in microcirculatory flows, however, little is known about the transport characteristics of red blood cell aggregates in branching geometries. This work reports on the fluxes of red blood cell aggregates of various sizes in a T-shaped microchannel, aiming to clarify the effects of different flow conditions in the outlet branches of the channel. Image analysis techniques, were utilised, and moderately aggregating human red blood cell suspensions were tested in symmetric (∼50-50%) and asymmetric flow splits through the two outlet (daughter) branches...

INTRODUCTION: Red blood cell distribution width (RDW) and bilirubin have been proved to be prognostic factors for various types of cancer. However, their prognostic value in patients with gastric cancer (GC) remains largely unknown. METHODS: To verify whether RDW and bilirubin are prognostic factors for patients with GC, we performed a cross-sectional study to analyze the relationship between RDW, bilirubin, and the clinical characteristics of patients with GC. Medical records of all newly diagnosed and pathologically proved patients with GC admitted to Changzheng Hospital between January 2016 and July 2016 were retrospectively reviewed...

The hawksbill turtle, Eretmochelys imbricata, is a marine chelonian with a circum-global distribution, but the species is critically endangered and has nearly vanished from the eastern Pacific. Although reference blood parameter intervals have been published for many chelonian species and populations, including nesting Atlantic hawksbills, no such baseline biochemical and blood gas values have been reported for wild Pacific hawksbill turtles. Blood samples were drawn from eight hawksbill turtles captured in near shore foraging locations within the Galápagos archipelago over a period of four sequential years; three of these turtles were recaptured and sampled on multiple occasions...

BACKGROUND Atrial fibrillation (AF) is one of the most critical and frequent arrhythmias precipitating morbidities and mortalities. The complete blood count (CBC) test is an important blood test in clinical practice and is routinely used in the workup of cardiovascular diseases. This systematic review with meta-analysis aimed to determine the strength of evidence for evaluating the association of hematological parameters in the CBC test with new-onset and recurrent AF. MATERIAL AND METHODS We conducted a meta-analysis of observational studies evaluating hematologic parameters in patients with new-onset AF and recurrent AF...

STUDY OBJECTIVE: Multiple studies nationwide and at single hospitals have examined changes over time in the incidence of perioperative red blood cell (RBC) transfusion. However, the cost of RBC transfusions is related to the number of RBC units transfused, not to the incidence. We evaluate whether the readily available incidence of RBC transfusion can be used as a valid surrogate measure. DESIGN: Observational retrospective study. SETTING: One tertiary, academic hospital...

BACKGROUND: Changes in platelet indices have been reported in patients with panic disorder (PD). However, previous study findings are contradictory and inconclusive. The aim of this study was to evaluate and compare the platelet indices in patients with PD. MATERIALS AND METHODS: Patients with PD (n = 123) and healthy controls (n = 133) were enrolled in this case control study. The platelet indices (mean platelet volume [MPV] and platelet distribution width [PDW]) along with red blood cell (RBC) indices (RBC count and red cell distribution width [RDW]) were compared between the two groups using the unpaired t-test...

The microcirculation is responsible for blood flow regulation and red blood cell distribution throughout individual organs. Patients with circulatory shock have acute failure of the cardiovascular system in which there is insufficient delivery of oxygen to meet metabolic tissue requirements. All subtypes of shock pathophysiology have a hypovolemic component. Fluid resuscitation guided by systemic hemodynamic end points is a common intervention. Evidence shows that microcirculatory shock persists even after optimization of macrocirculatory hemodynamics...

Studies on the haemodynamics of human circulation are clinically and scientifically important. In order to investigate the effect of deformation and aggregation of red blood cells (RBCs) in blood flow, a computational technique has been developed by coupling the interaction between the fluid and the deformable RBCs. Parallelization was carried out for the coupled code and a high speedup was achieved based on a spatial decomposition. In order to verify the code's capability of simulating RBC deformation and transport, simulations were carried out for a spherical capsule in a microchannel and multiple RBC transport in a Poiseuille flow...

We present a novel automated system for morphology analysis of red blood cells (RBC) under flow. RBC concentrates collected by blood banks for transfusions are stored for periods of up to several weeks, during which time a number of changes occur, collectively termed the storage lesion. Typically the extent of hemolysis is the defining criterion to determine the acceptability of the RBCs for transfusions. Morphological changes are related with biochemical alteration during the storage of RBCs. The typical blood smear procedure for determining such changes is a labor-intensive and potentially biased manual process...
