OBJECTIVES: Current evidence suggests that subclinical inflammation plays a significant role in the development of hyperemesis gravidarum (HEG). Simple hematological markers, such as mean platelet volume (MPV), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), have been shown to reflect inflammatory burden and disease activity in several disorders. This study aimed to determine the diagnostic value of these hematological parameters for HEG. MATERIAL AND METHODS: A total of 54 HEG patients and 58 age- and gestational-age-matched control subjects were studied...

The purpose was to evaluate the predictive value of baseline neutrophil to lymphocyte ratio (NLR) level in the incidence of grade 3 or higher radiation induced lung injury (RILI) for lung cancer patients. A retrospectively analysis with 166 lung cancer patients was performed. All of the enrolled patients received chemoradiotherapy at our hospital between April 2014 and May 2016. The Cox proportional hazard model was used to identify the potential risk factors for RILI. In this cohort, the incidence of grade 3 or higher RILI was 23...

BACKGROUND AND PURPOSE: Blood-brain barrier (BBB) disruption detected on magnetic resonance imaging (MRI) in acute ischemic stroke as a hyperintense acute reperfusion marker (HARM) is associated with upregulation of matrix metalloproteinase-9 (MMP-9). Although activated leukocytes, including monocytes, are the main source of MMPs, limited data exist to support relationship between leukocyte activation and BBB disruption in patients with acute ischemic stroke. The goal of this study is to investigate the relationship between neutrophils, lymphocytes, and monocytes with BBB disruption detected as HARM (+) in patients with acute ischemic stroke...

BACKGROUND AND AIMS: Parameters derived from complete blood count such as mean platelet volume (MPV), neutrophil to lymphocyte (NLR), platelet to lymphocyte (PLR) are recently proposed as measures of inflammation in addition to C-reactive protein (CRP), a classical inflammatory marker. Significant association of these parameters with atherosclerosis and complications have increasingly been reported. Our aim is to evaluate relationship between these parameters and presence of myocardial viability assessed with positron emission tomography (PET) in patients with ischemic cardiomyopathy...

We propose a framework to detect and segment nuclei and segment overlapping cytoplasm in cervical cytology images. This is a challenging task due to folded cervical cells with spurious edges, poor contrast of cytoplasm and presence of neutrophils and artifacts. The algorithm segments nuclei and cell clumps in extended depth of field (EDF) images and uses volume images to segment overlapping cytoplasm. The boundaries are first approximated by a defined similarity metric and are refined in two steps by reducing concavity, iterative smoothing and outliers removal...

BACKGROUND AND PURPOSE: Although preclinical studies have shown inflammation to mediate perihematomal edema (PHE) after intracerebral hemorrhage, clinical data are lacking. Leukocyte count, often used to gauge serum inflammation, has been correlated with poor outcome but its relationship with PHE remains unknown. Our aim was to test the hypothesis that leukocyte count is associated with PHE growth. METHODS: We included patients with intracerebral hemorrhage admitted to a tertiary-care stroke center between 2011 and 2015...

Spontaneous bacterial peritonitis (SBP) is a potentially life-threatening complication of ascites diagnosed by paracentesis. We determined predictors of SBP to facilitate patient selection. The 301 paracenteses performed in 119 patients (51 women, 68 men) from July to November 2015 were retrospectively reviewed. Presentation, lab data, depth of the deepest ascites pocket on ultrasound, total volume of ascites removed, absolute neutrophil count, and complications were studied. Of 301 paracenteses, 16 (5%) diagnosed SBP...

Neutrophils and monocytes are key components of the innate immune system that undergo age-associated declines in function. This study compared the impact of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on immune function in sedentary adults. Twenty-seven (43 ± 11 years) healthy sedentary adults were randomized into ten weeks of either a HIIT (>90% maximum heart rate) or MICT (70% maximum heart rate) group training program. Aerobic capacity (VO2peak), neutrophil and monocyte bacterial phagocytosis and oxidative burst, cell surface receptor expression, and systemic inflammation were measured before and after the training...

The anti-inflammatory effects of boldine and reticuline isolated from Litsea cubeba were evaluated by using xylene-induced ear edema and carrageenan-induced paw edema in mice and rats. Our results demonstrated that intragastric administration with boldine and reticuline significantly mitigated ear weight in mice and decreased paw volume in rats. A combination administration of boldine (0.5 mg/kg) + reticuline (0.25 mg/kg) resulted in a potentiated inhibition in these two models. In parallel, boldine or reticuline reduce the infiltration of neutrophil leukocytes in rat paw tissue, respectively, and the combination of the two groups performed a better anti-inflammatory activity as shown in histopathologies...

Toll-like receptor 2 (TLR2) was recently shown to contribute to secondary brain damage after intracerebral hemorrhage (ICH), although the molecular mechanisms of this contribution are elusive. In this study, we tested the hypothesis that hemin functions as a TLR2 endogenous agonist, causing proinflammatory astrocyte activation and secondary brain damage after ICH. Hemin administration to the mouse brain striatum induced ICH injury and neurological deficits, however, the brain injury volume and neurological deficits due to hemin injection were significantly reduced in TLR2 knock-out (KO) mice...

Titanium dioxide nanoparticles (TiO2 NPs) have been extensively used in industry, medicine, and daily life, and have shown potential toxic effects for animals or humans. We noted that the effects of TiO2 NPs on the immune system and its mechanism of action in animals or humans have not been elucidated. Thus, mice were exposed to the TiO2 NPs (0, 1.25, 2.5, or 5 mg kg(-1) body weight) for 9 consecutive months. Exposure to TiO2 NPs was accumulated in the thymus, leading to a decrease in body weight and increases in the weight of the thymus or thymus indices...

BACKGROUND: Debate around the value of laboratory tests in establishing the diagnosis of acute appendicitis (AA) still continues. This prospective study aimed to investigate the changes in mean platelet volume (MPV), platelet distribution width (PDW), and red cell distribution width (RDW) with the diagnosis of acute appendicitis. METHOD: 200 patients who underwent emergency appendectomy were included. According to postoperative histology, patients were divided into three groups: acute non-complicated, acute complicated appendicitis (positive appendicectomy groups), and negative appendectomy group...

It has been established that voltage-gated proton channels (VSOP/Hv1), encoded by Hvcn1, support reactive oxygen species (ROS) production in phagocytic activities of neutrophils (El Chemaly et al. 2010) and antibody production in B lymphocytes (Capasso et al. 2010). VSOP/Hv1 is a potential therapeutic target for brain ischemia, since Hvcn1 deficiency reduces microglial ROS production and protects brain from neuronal damage (Wu et al. 2012). In the present study, we report that VSOP/Hv1 has paradoxical suppressive role in ROS production in microglia...

BACKGROUND: Sepsis most often presents to the emergency department (ED), and delayed detection is harmful. The white blood count (WBC) is often used to detect sepsis, but changes in WBC size also correspond with sepsis. We sought to determine if volume increases of circulating immune cells adds value to the WBC for early sepsis detection in the ED. METHODS: A blinded, prospective cohort study was conducted in two different ED populations within a large academic hospital...
