    To assess whether inflammatory markers measured in urine and blood during acute bronchiolitis in infancy were associated with asthma, lung function, bronchial hyper-responsiveness (BHR) and atopy at 11 years of age. We included 105 children hospitalised for bronchiolitis during their first year of life. At hospitalisation, urinary (U-) eosinophil protein X, U-leukotriene E4 , U-prostaglandin 9α, 11β-PGF2 and blood eosinophil counts were measured. Ninety-five children (90%) were available for follow-up at 11 years of age. At follow-up, higher blood eosinophil counts obtained during bronchiolitis were observed in the group with asthma than in the group without asthma (median 0.27 versus 0.09 × 10(9) /L, respectively, p = 0.048). By regression analyses, blood eosinophil counts during the acute bronchiolitis were positively associated with BHR (p = 0.006) and negatively associated with forced expiratory volume in first second (p = 0.025) at 11 years of age. None of the other inflammatory markers were associated with asthma, lung function, BHR or atopy at 11 years of age. Eosinophil inflammation during bronchiolitis may have a long-term impact on lung function and airway responsiveness. The associations could be related to virus-host interactions during bronchiolitis or to predisposed children. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    The circulating blood volume accounts for 8% of the body weight, of which 45% comprises cellular components (blood cells) and 55% liquid components. We can measure the number and morphological features of blood cells (leukocytes, red blood cells, platelets), or count the amount of hemoglobin in a complete blood count: (CBC). Blood counts are often used to detect inflammatory diseases such as infection, anemia, a bleeding tendency, and abnormal cell screening of blood disease. This count is widely used as a basic data item of health examination. In recent years, clinical tests before consultation have become common among outpatient clinics, and the influence of laboratory values on consultation has grown. CBC, which is intended to count the number of raw cells and to check morphological features, is easily influenced by the environment, techniques, etc., during specimen collection procedures and transportation. Therefore, special attention is necessary to read laboratory data. Providing correct test values that accurately reflect a patient's condition from the laboratory to clinical side is crucial. Inappropriate medical treatment caused by erroneous values resulting from altered specimens should be avoided. In order to provide correct test values, the daily management of devices is a matter of course, and comprehending data variables and positively providing information to the clinical side are important. In this chapter, concerning sampling collection, blood collection tubes, dealing with specimens, transportation, and storage, I will discuss their effects on CBC, along with management or handling methods.

    The design, fabrication, and tests of a prototype white blood cell counting system for use in the Skylab IMSS are presented. The counting system consists of a sample collection subsystem, sample dilution and fluid containment subsystem, and a cell counter. Preliminary test results show the sample collection and the dilution subsystems are functional and fulfill design goals. Results for the fluid containment subsystem show the handling bags cause counting errors due to: (1) adsorption of cells to the walls of the container, and (2) inadequate cleaning of the plastic bag material before fabrication. It was recommended that another bag material be selected.

    2015-07-15

    White blood cell count is an important indicator of each individual's health condition. An abnormal white blood cell count usually results from an infection, cancer, or other conditions that trigger systemic inflammation responses. White blood cell count also provides predictive information on the incidence of cardiovascular diseases and Type 2 diabetes. Therefore, monitoring white blood cell count on a regular basis can potentially help individuals to take preventive measures and improve healthcare outcomes. Currently, white blood cell count is primarily conducted in centralized laboratories, and it requires specialized equipment and dedicated personnel to perform the test and interpret the results. So far there has been no rapid test that allows white blood cell count in low-resource settings. In this study, we have demonstrated a vertical flow platform that quantifies white blood cells by trapping them in the paper. White blood cells were tagged with gold nanoparticles, and flowed through the paper via a small orifice. The white blood cell count was determined by measuring the colorimetric intensity of gold nanoparticles on the surface of white blood cells that were trapped in the paper mesh. Using this platform, we were able to quantify white blood cells in 15 μL of blood, and visually differentiate the abnormal count of white blood cells from the normal count. The proposed platform enabled rapid white blood cell count in low resource settings with a small sample volume requirement. Its low-cost, instrument-free operations would be attractive for point-of-care applications.

  19. Blood Level of Polymorphonuclear Neutrophil Leukocytes and Bronchial Hyperreactivity in Chronic Obstructive Pulmonary Disease

    Science.gov (United States)

    Cukic, Vesna

    2015-01-01

    Introduction: Polymorphonuclear neutrophil leukocytes (PMNL) have an important defensive role against various microorganisms and other agents, but by liberating various substances, first of all the superoxide anion (O 2¯), they can damage the bronchial mucosa and influence the development of bronchial inflammation which is the fundamental of bronchial hyperreactivity (BHR). Objective: to show the role of the PMNL for development and level of BHR in patients with chronic obstructive pulmonary disease (COPD). Material and methods: We observed 160 patients with COPD treated in Clinic for Pulmonary Diseases and TB “Podhrastovi” Sarajevo during three years :from 2012 to 2014. They were divided into groups and subgroups according to the first registration of BHR in the course of illness and to the number of exacerbations of the disease in one year. The number of blood PMNL was measured in a stable state of disease at the begging and at the end of investigation. Results: The number of blood PMNL was significantly greater in patients with 3 or more exacerbations per one year (p <0.01). Patients with BHR had significantly greater number blood PMNL than patients without BHR (p< 0.05). Patients with 3 exacerbations per year had a statistically significant increase of number of PMNL between first and last examination (p<0.01). Conclusion: There is statistically significant correlation between the number of blood PMNL and the level of BHR in COPD, but future examination need to be done to determine real role and mode of action of PMNL for these processes.

    Full Text Available We observed sixty patients with allergic bronchial asthma (ABA and 54 with non-allergic bronchial asthma (NABA. Quantitative SOCS3 and SOCS5 mRNA expression was evaluated by means of real-time PCR. Eighteen healthy persons served as a control group. In patients with bronchial asthma (irrespectively of pathogenetic form, a significant increase of SOCS3 transcription factor expression was detected in peripheral blood mononuclears, as compared with control group. This increase was more pronounced in NABA group. The mRNA SOCS5 level was significantly decreased in bronchial asthma patients, as compared to control group, especially, in ABA subgroup rather than in NABA patients. Thus, an increased expression of SOCS3 mRNA in BA patients could be regarded as a protective antiinflammatory response Decrease of SOCS5 mRNA expression in patients with bronchial asthma (being more pronounced in ABA, may be indicative for a deficiency in negative feedback regulation of gene transcription in allergic bronchial asthma.

    Full Text Available Objective: To observe the effect of azithromycin on the function of dendritic cells (DCs originated from peripheral blood mononuclear cells (PBMCs in children with bronchial asthma so as to explore the action mechanism of azithromycin in immunoregulation.Methods: Totally 32 children with bronchial asthma were selected as observation group, and 30 healthy children through physical examination as control group. Under sterile condition, PBMCs were prepared using density gradient centrifugation, and DCs were induced by recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF and recombinant human interleukin-4 (rhIL-4 in vitro. Observation group was intervened by different concentrations of azithromycin (0.0, 0.1 and 10.0 mg/L, while control group didn’t receive any intervention. The expression rates of CD80, CD83 and CD86 on the surface of DCs were detected using flow cytometry, and the levels of IL-10 and IL-12 in the cultured supernate were measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA.Results: The expression rate of CD86 was significantly higher, whereas the levels of IL-10 and IL-12 were markedly lower in observation group than in control group, and the differences were statistically significant (P<0.05 or P<0.01. In observation group, the level of IL12 was positively correlated with that of IL-10 (r=0.736, P<0.01, but no correlation was shown between the levels of IL-10 and IL-12 in control group (r=0.228, P>0.05. Significant difference was not shown by comparison to the expression rates of CD83, CD80 and CD86 on the surface of DCs intervened by azithromycin at 0.0, 0.1 and 10.0 mg/L (P>0.05. The levels of IL-10 at 0.1 and 10.0 mg/L were dramatically lower than that at 0.0 mg/L (P<0.01, and the level of IL-12 at 0.1 mg/L was notably lower than those at 0.0 and 10.0 mg/L (P<0.01.Conclusion: DCs in children with bronchial asthma are imperfect, and are mainly marked by increase of CD86

    Full Text Available Background Cardiovascular disease is resulted from malfunctioning’s of heart as well as blood vessels. More than two decades ago it was noted that the number of white blood cells can be an indicated of the existence of such disease. Platelet activation and aggregation are among the include processes. That are considered in pathophysiology of a coronary heart disease. However there seems to be a paucity of research on platelet count in patients suffering from obesity. Moreover although previous studies have indicated a positive correlation between platelet and white blood cells. Counts and mortality from coronary heath disease, how this might correlate with obesity is an issue still in need of more attention. Objectives The present study was designed to evaluate platelet count and white blood cell count in those patients who suffer from obesity as compared with control subjects who were not obese. Methods In this cross-sectional study, there were a total of 1024 Iranian subjects living in Hamedan include, staff of Islamic Azad University of Hamedan and subjects who referred to Ekbatan hospital in Hamedan during the period of 6 months randomly and staff of Islamic Azad University of Hamedan. The absence of infectious disease was confirmed by a general practitioner. Finally, the samples included 486 subjects, 254 male, and 232were females. Body mass index was calculated. Waist circumference in the Iranian subjects, at least in men 89 (cm and women 91 (cm was considered. White blood cell and platelet count was measured. T-test and Pearson’s correlation were run to analyze the collected data through SPSS software version 16. Results The average age of the subjects was 34.75 ± 8.1 years. The body mass indexes in 7.6 percent of men and 15.7 of women were greater than 30 (kg/m2. The averages of waist circumference in men and women was 1.04 ± 0.5 and 89.3 ± 10.2 (cm, respectively. Also there seemed to be a significant correlation between waist

  7. Complete blood count reference intervals for healthy Han Chinese adults.

    Directory of Open Access Journals (Sweden)

    Xinzhong Wu

    Full Text Available Complete blood count (CBC reference intervals are important to diagnose diseases, screen blood donors, and assess overall health. However, current reference intervals established by older instruments and technologies and those from American and European populations are not suitable for Chinese samples due to ethnic, dietary, and lifestyle differences. The aim of this multicenter collaborative study was to establish CBC reference intervals for healthy Han Chinese adults.A total of 4,642 healthy individuals (2,136 males and 2,506 females were recruited from six clinical centers in China (Shenyang, Beijing, Shanghai, Guangzhou, Chengdu, and Xi'an. Blood samples collected in K2EDTA anticoagulant tubes were analyzed. Analysis of variance was performed to determine differences in consensus intervals according to the use of data from the combined sample and selected samples.Median and mean platelet counts from the Chengdu center were significantly lower than those from other centers. Red blood cell count (RBC, hemoglobin (HGB, and hematocrit (HCT values were higher in males than in females at all ages. Other CBC parameters showed no significant instrument-, region-, age-, or sex-dependent difference. Thalassemia carriers were found to affect the lower or upper limit of different RBC profiles.We were able to establish consensus intervals for CBC parameters in healthy Han Chinese adults. RBC, HGB, and HCT intervals were established for each sex. The reference interval for platelets for the Chengdu center should be established independently.

  8. Is automated platelet counting still a problem in thrombocytopenic blood?

    Directory of Open Access Journals (Sweden)

    Raimundo Antônio Gomes Oliveira

    Full Text Available CONTEXT: Reliable platelet counting is crucial for indicating prophylactic platelet transfusion in thrombocytopenic patients. OBJECTIVE: To evaluate the precision and accuracy of platelet counting for thrombocytopenic patients, using four different automated counters in comparison with the Brecher & Cronkite reference method recommended by the International Committee for Standardization in Hematology (ICSH. TYPE OF STUDY: Automated platelet counting assessment in thrombocytopenic patients. SETTING: Hematology Laboratory, Hospital do Servidor Público Estadual de São Paulo, and the Hematology Division of Instituto Adolfo Lutz, São Paulo, SP, Brazil. MAIN MEASUREMENTS: Brecher & Cronkite reference method and four different automated platelet counters. PARTICIPANTS: 43 thrombocytopenic patients with platelet counts of less than 30,000/µl RESULTS: The ADVIA-120 (Bayer, Coulter STKS, H1 System (Technicom-Bayer and Coulter T-890 automatic instruments presented great precision and accuracy in relation to laboratory thrombocytopenic samples obtained by diluting blood from normal donors. However, when thrombocytopenic patients were investigated, all the counters except ADVIA (which is based on volume and refraction index showed low accuracy when compared to the Brecher & Cronkite reference method (ICSH. The ADVIA counter showed high correlation (r = 0.947. However, all counters showed flags in thrombocytopenic samples. CONCLUSION: The Brecher & Cronkite reference method should always be indicated in thrombocytopenic patients for platelet counts below 30,000 plt /µl obtained in one dimensional counters.

    Absolute neutrophil count (ANC) is used clinically to monitor physiological dysfunctions such as myelosuppression or infection. In the research laboratory, ANC is a valuable measure to monitor the evolution of a wide range of disease states in disease models. Flow cytometry (FCM) is a fast, widely used approach to confidently identify thousands of cells within minutes. FCM can be optimised for absolute counting using spiked-in beads or by measuring the sample volume analysed. Here we combine the 1A8 antibody, specific for the mouse granulocyte protein Ly6G, with flow cytometric counting in straightforward FCM assays for mouse ANC, easily implementable in the research laboratory. Volumetric and Trucount™ bead assays were optimized for mouse neutrophils, and ANC values obtained with these protocols were compared to ANC measured by a dual-platform assay using the Orphee Mythic 18 veterinary haematology analyser. The single platform assays were more precise with decreased intra-assay variability compared with ANC obtained using the dual protocol. Defining ANC based on Ly6G expression produces a 15% higher estimate than the dual protocol. Allowing for this difference in ANC definition, the flow cytometry counting assays using Ly6G can be used reliably in the research laboratory to quantify mouse ANC from a small volume of blood. We demonstrate the utility of the volumetric protocol in a time-course study of chemotherapy induced neutropenia using four drug regimens.

    White blood cell (WBC) analysis provides rich information in rapid diagnosis of acute bacterial and viral infections as well as chronic disease management. For patients with immune deficiency or leukemia WBC should be persistently monitored. Current WBC counting method relies on bulky instrument and trained personnel and is time consuming. Rapid, low-cost and portable solution is in highly demand for point of care test. Here we demonstrate a label-free smartphone based electrochemical WBC counting device on microporous paper with patterned gold microelectrodes. WBC separated from whole blood was trapped by the paper with microelectrodes. WBC trapped on the paper leads to the ion diffusion blockage on microelectrodes, therefore cell concentration is determined by peak current on the microelectrodes measured by a differential pulse voltammeter and the quantitative results are collected by a smartphone wirelessly within 1min. We are able to rapidly quantify WBC concentrations covering the common physiological and pathological range (200-20000μL(-1)) with only 10μL sample and high repeatability as low as 10% in CoV (Coefficient of Variation). The unique smartphone paper electrochemical sensor ensures fast cell quantification to achieve rapid and low-cost WBC analysis at the point-of-care under resource limited conditions.

    Alterations of mitochondrial DNA copy number (mtDNAcn) in the blood (mitochondrial to nuclear DNA ratio) appear associated with several systemic diseases, including primary mitochondrial disorders, carcinogenesis, and hematologic diseases. Measuring mtDNAcn in DNA extracted from whole blood (WB) instead of from peripheral blood mononuclear cells or buffy coat may yield different results due to mitochondrial DNA present in platelets. The aim of this work is to quantify the contribution of platelets to mtDNAcn in whole blood [mtDNAcn(WB)] and to propose a correction formula to estimate leukocytes' mtDNAcn [mtDNAcn(L)] from mtDNAcn(WB). Blood samples from 10 healthy adults were combined with platelet-enriched plasma and saline solution to produce artificial blood preparations. Aliquots of each sample were combined with five different platelet concentrations. In 46 of these blood preparations, mtDNAcn was measured by qPCR. MtDNAcn(WB) increased 1.07 (95%CI 0.86, 1.29; p<0.001) per 1000 platelets present in the preparation. We proved that leukocyte count should also be taken into account as mtDNAcn(WB) was inversely associated with leukocyte count; it increased 1.10 (95%CI 0.95, 1.25, p<0.001) per unit increase of the ratio between platelet and leukocyte counts. If hematological measurements are available, subtracting 1.10 the platelets/leukocyte ratio from mtDNAcn(WB) may serve as an estimation for mtDNAcn(L). Both platelet and leukocyte counts in the sample are important sources of variation if comparing mtDNAcn among groups of patients when mtDNAcn is measured in DNA extracted from whole blood. Not taking the platelet/leukocyte ratio into account in whole blood measurements, may lead to overestimation and misclassification if interpreted as leukocytes' mtDNAcn.

Not taking the platelet/leukocyte ratio into account in whole blood measurements, may lead to overestimation and misclassification if interpreted as leukocytes' mtDNAcn. PMID:27736919

  13. Ancestry informative markers and complete blood count parameters in Brazilian blood donors

    Full Text Available A complete blood count is very useful in clinical diagnoses when reference ranges are well established for the population. Complete blood counts and allele frequencies of Ancestry Informative Markers (AIMs were analyzed in Brazilians with the aim of characterizing the hematological values of an admixed population. Positive associations were observed between gender and neutrophils, monocytes, eosinophils, erythrocytes, hemoglobin, hematocrit, MCV, MCHC and platelet counts. No significant differences were found for age, alcohol consumption, educational status, ethnicity, smoking in respect to the complete blood count values. In general, men had higher red blood cell values, while women had higher values for white blood cells and platelets. The study of the population was highly heterogeneous with mean proportions (± SE of African, European and Amerindian ancestry being 49.0 ± 3.0%, 44.0 ± 9.0% and 7.0 ± 9.0%, respectively. Amerindian ancestry showed limited contribution to the makeup of the population, but estimated ancestral proportions were statistically significant (r = 0.9838; P<0.001. These hematologic values are similar to Afro-Americans, another admixed population.

    There is no automated, accurate assay for the enumeration of residual red blood cells (rRBCs) in non-RBC components for transfusion, despite the potential risk of allo-immunization when mismatched components are transfused. The automated ADVIA 120 cerebrospinal fluid (CSF) assay, which is approved to count RBCs and WBCs in CSF samples, was optimized and tested to measure rRBC in platelet concentrate (PC) and plasma components. Sample dilution, incubation time and reagent volume were optimized for use with non-RBC blood products. The assay was linear (R(2) = 0·99), even at low rRBCs counts. Intra- and inter-assay variation gave coefficients of variance (CV) between 2·2 and 9·4% and 2·6 and 14·9%, respectively, depending on rRBC levels. Good correlation (r = 0·995) was found between the automated assay and manual counting, which is considered the gold standard. Using the automated assay, the range of rRBCs (count/unit) in buffy-coat platelet concentrate (PCs) was 27-5505 × 10(6) and in apheresis PCs was 1-361 × 10(6). The ADVIA CSF assay is a sensitive, precise and accurate means to assess rRBC counts in non-RBC components. © 2012 The Author(s). Vox Sanguinis © 2012 International Society of Blood Transfusion.

    Current laboratory standards from Clinical Laboratory Standards Institute (CLSI) and manufacturer's (Becton Dickinson) data indicate that under-filling K(2)EDTA blood collection tubes can result in erroneous hematology values. To accommodate under-filled tubes and reduce collection volumes while optimizing our automation, we explored the acceptable limit of under-filled tubes for hematology values. We collected 8.0 ml of blood from 30 normal adult volunteers. Each donation was aliquoted in the following volumes: 4.0, 2.0, 1.0, 0.5 ml x 2. These samples were analyzed within 1 h of blood collection on Sysmex XE-2100 (Sysmex America Inc., Mundelein, IL, USA) for complete blood count, reticulocyte, and white blood cell differentials. Results of the under-filled tubes were compared to those of the standard volume. The Deming regression analysis show excellent correlation for all parameters between each under-filled blood collection volume compared to a standard 4 ml volume. The Bland and Altman analysis shows good agreement between both 1.0 and 2.0 ml compared to a 4.0 ml volume. The 0.5 ml compared to a 4.0 ml volume, however, shows increased variation on many parameters. In addition all three collection volumes show negative bias compared to the standard volume for platelet count, but the difference is considered insignificant with a percent difference of 5.5%, 3.2%, and 1.5% for 0.5, 1.0, and 2.0 ml collection volume respectively. Finally for 0.5 ml collection volume we noticed a low level of false positive flagging rate for white blood cell. Acceptable complete blood count values of under-filled powdered K(2)EDTA tubes can be obtained with as little as 1.0 ml of blood.

    Complete blood cell count (CBC) data from heparinized blood gas (H-Gas) samples were verified with primary focus on the platelet count (PLT). When a part of H-Gas sample was taken to a separation tube from the blood collection syringe and CBC of the sample in the separation tube was repeatedly measured (Procedure 1), the PLT from 5 samples relative to that obtained immediately after the separation was gradually reduced to 72.6-94.2% during serial measurements (every 5 minutes, up to 30 minutes). The change in the scattergram pattern suggested that this PLT decrease was due to the formation of platelet clumps. The white blood cell count (WBC), red blood cell count (RBC), hemoglobin (Hb) and hematocrit (Ht) values did not significantly change during the repeated measurements. On the other hand, PLT was significantly improved to 96.8-99.8% when the H-Gas sample was kept in the blood collection syringe so as to minimizing the exposure to the air, and the sample for the measurement from H-Gas was taken every time to separation tube from the syringe, followed by CBC measurement without delay (Procedure 2). In addition, while there were significant variations (CV: 11.8-18.2%) in PLT reproducibility among H-Gas samples by Procedure 1, measurements utilizing the Procedure 2 resulted in much smaller variations (CV: 2.2-3.7%). Thus the CBC data obtained from H-Gas samples were equivalent to those from EDTA samples when the Procedure 2 was applied. These data suggest that H-Gas samples can be used for the accurate CBC measurement, including PLT, by applying the Procedure 2.

    Full Text Available The present study was undertaken to see the effect of mastitic pathogens on the blood and milk counts of Murrah buffaloes. Milk and blood samples were collected from 9 mastitic Murrah buffaloes. The total leucocyte Counts (TLC and Differential leucocyte counts (DLC in blood were within normal range and there was a non-significant change in blood counts irrespective of different mastitic pathogens. Normal milk quarter samples had significantly (P<0.01 less Somatic cell counts (SCC. Lymphocytes were significantly higher in normal milk samples, whereas infected samples had a significant increase (P<0.01 in milk neutrophils. S. aureus infected buffaloes had maximum milk SCC, followed by E. coli and S. agalactiae. Influx of neutrophils in the buffalo mammary gland was maximum for S. agalactiae, followed by E.cli and S. aureus. The study indicated that level of mastitis had no affect on blood counts but it influenced the milk SCC of normal quarters.

    Elevated eosinophil count was shown to be associated with the development of cholesterol embolization syndrome, a potentially life-threatening condition, after catheter-based procedures. We investigated the association between stages of chronic kidney disease (CKD) and the absolute eosinophil count (AEC) among cardiac patients. CKD stages were determined solely on the estimated glomerular filtration rate or requirement for hemodialysis. Eosinophilia is defined as an eosinophil count exceeding 500/μL. A total of 1022 patients were enrolled in the current study, and eosinophil counts (/μL) in the first through fourth eosinophil count quartiles were blood pressure, and total white blood cell count. Similarly, after adjustment for the same variables, eosinophilia was associated with severe renal dysfunction with an odds ratio of 2.60 (95 % confidence interval, 1.08-6.26, P count was positively associated with higher CKD stages among cardiology patients, some fraction of which might be related to subclinical cholesterol embolization.

    This retrospective cross-sectional study examined if the white cell count (WCC) is increased in women with polycystic ovary syndrome (PCOS) and if so, is it due to PCOS or to the associated obesity? Body mass index (BMI) was calculated and body composition was measured using bioelectrical impedance analysis. Of the 113 women studied, 36 had PCOS and 77 did not. The mean WCC was higher in the PCOS group compared with the non-PCOS group (8.9 x 10(9)\\/l vs 7.4 x 10(9)\\/l p = 0.002). This increase was due to a higher neutrophil count (5.6 x 10(9)\\/l vs 4.3 x 10(9)\\/l; p = 0.003). There was a leucocytosis (WCC >11 x 10(9)\\/l) present in 19% of the PCOS group compared with 1% in the non-PCOS group (p < 0.001). The neutrophil count was abnormally high (>7.7 x 10(9)\\/l) in 14% of the PCOS group compared with 4% in the non-PCOS group (p < 0.001). On regression analysis, however, the only independent variable which explained both the increased WCC and the increased neutrophil count was PCOS. We found that PCOS is associated with an increased WCC due to increased neutrophils, which supports the evidence that PCOS is associated with low-grade inflammation. The increase appears to be due to the underlying PCOS, and not to the increased adiposity associated with PCOS.

    Full Text Available To investigate the relationship between local responsiveness and allergic symptoms, bronchial and nasal responsiveness were measured in the following four groups of subjects: (i bronchial asthma patients with serum house dust mite (HDM-specific IgE antibody; (ii allergic rhinitis patients with serum HDM-specific IgE antibody; (iii normal control subjects with HDM-specific IgE antibody; and (iv normal control subjects without IgE antibody specific for 10 common aero-allergens. Bronchial hyperresponsiveness was detected in all subjects with asthma (group 1 and in some subjects from groups 2 and 3, but not in subjects from group 4. Nasal hyperresponsiveness was found in all subjects with allergic rhinitis (group 2 and in some subjects from groups 1 and 3, but not in subjects from group 4. These findings indicate that local hyperresponsiveness of the non-diseased organ is influenced by an individual's atopic status. Interleukin (IL-4 and IL-5 production by peripheral blood mononuclear cells (PBMC was measured after stimulation with HDM in groups 1, 2 and 3 and was found to be similar in all three groups. A correlation between bronchial hyperresponsiveness and in vitro cytokine production was noted in asthma patients. These results suggest that the capacity of IL-4 or IL-5 production by PBMC may reflect local hyperresponsiveness in case of asthma.

    We demonstrate that the concentration of a red blood cell solution under physiological conditions can be determined by electrochemical voltammetry. The magnitude of the oxygen reduction currents produced at an edge-plane pyrolytic graphite electrode was diagnosed analytically at concentrations suitable for a point-of-care test device. The currents could be further enhanced when the solution of red blood cells was exposed to hydrogen peroxide. We show that the enhanced signal can be used to detect red blood cells at a single entity level. The method presented relies on the catalytic activity of red blood cells towards hydrogen peroxide and on surface-induced haemolysis. Each single cell activity is expressed as current spikes decaying within a few seconds back to the background current. The frequency of such current spikes is proportional to the concentration of cells in solution.

    Full Text Available Allergic respiratory disorders are fairly common visiting cases in pediatrics outpatient department (OPD. With an appropriate history and detailed examination, diagnosis may not be problematic. Routine investigation may not contribute much to the final diagnosis but may help in ruling out other possibilities. This study was done to evaluate sensitivity and specificity of blood or nasal eosinophilia in subjects suffering from allergic respiratory disorders and also to assess the feasibility of nasal cytogram which is a simple, economical and reliable investigation in allergic respiratory disorders. This is a prospective clinical correlation study of patients attending outpatient department. 100 subjects aged between 2-18 years of either sex were selected for the estimation of eosinophil count in nasal and peripheral smear in allergic respiratory disorders. All allergic respiratory cases based on eosinophillia. The nasal and blood eosinophilia were compared with each other and clinical findings of allergic rhinitis with or without asthma were studied. In this study peak age incidence was seen between 11-18 years and it was more common in males. Rhinorrhoea, pale mucosa and nasal obstruction were common findings in allergic rhinitis with bronchial asthma. Nasal eosinophilia was seen in 52.4% and 64.9% of cases of allergic rhinitis and allergic rhinitis with asthma respectively. Blood eosinophilia was seen in 54% and 56.8% of cases of allergic rhinitis with asthma respectively. Nasal cytogram which is a simple, economical and non- invasive procedure can be used as an alternative to invasive peripheral smear eosinophilia as both are equally efficacious in diagnosing allergic respiratory diseases.

We used multivariable logistic regression to calculate odds ratios (ORs) for the 4-year incidences of hematological malignancies and mortality between the eosinophil counts and a reference count of 0.16 × 10(9) /l which was the median eosinophil count in our data. Risks of hematological malignancies and mortality increased above the median eosinophil count. At the 99th percentile, corresponding to an eosinophil count of 0.75 × 10(9) /l, risks of hematological malignancies were increased more than twofold with OR (95% C.I.) of 2.39 (1.91-2.99). Interestingly, risks reached a plateau around an eosinophil count of 1.0 × 10(9) /l. Risks also increased when the eosinophil count approached zero. Here, counts associated relatively more with acute myeloid leukemia and myelodysplastic syndromes whereas counts above 0.16 × 10(9) /l associated more with myeloproliferative neoplasms. Eosinophil counts associate with hematological malignancies and mortality even below the definition of eosinophilia. The observed plateau of risks around 1.0 × 10(9) /l is important for physicians encountering patients with eosinophilia since even mild-to-moderate eosinophilia according to traditional definitions confers maximally increased risks of subsequent/subclinical hematological malignancy.

    Nucleated red blood cells (NRBCs) and reticulocytes are early and important measures of red blood cells' (RBCs) turnover, but little is known on how spurious hemolysis may affect the reliability of these parameters. Ten EDTA-anticoagulated samples were divided into three aliquots. The first was immediately tested, where-as the others (defined A and B) were mechanically hemolyzed by aspiration 5 and 10 times through a small-gauge needle. RBC, NRBC, and reticulocyte counts were performed on Sysmex XE-2100. An increasing amount of hemolysis was produced in hemolyzed aliquots A and B. The RBC and reticulocyte counts progressively decreased from the nonhemolyzed sample to hemolyzed aliquots 'A' and 'B'. The NRBC count increased in 3 of the 10 samples and decreased in the remaining seven. Hemolysis of venous blood samples may seriously jeopardize NRBC and reticulocyte counts. © 2012 Blackwell Publishing Ltd.

    Full Text Available Abstract. The aim of the study is to specify the levels of STAT6, and phospho-STAT6 under the influence of IL-4 in patients with bronchial asthma (BA. The samples from ten healthy controls and thirty-three BA patients with allergic and non-allergic clinical forms of different severity were under investigation. Peripheral blood lymphocytes were treated with 10 ng/ml of IL-4 (Sigma Aldrich, USA for 1 h. Then the proteins (STAT6 and phospho-STAT6 expressed in peripheral lymphocytes were analyzed by Western blot of cell lysates. Preparation of the cell lysates and Western blotting were carried out using standard procedures. Antibodies against phospho-STAT6 and STAT6 (10 ng/ml were used (Cell Signaling, USA. Levels of thespecific proteins were standardized according to β-actin (Cell Signaling, USA. Treatment with IL-4 caused an increase of phospho-STAT6 levels in lymphocytes of all BA patients, as compared with control group. In allergic BA, the phospho-STAT6 levels were significantly higher than in non-allergic clinical forms. Expression of STAT6 in lymphocytes of patients with severe BA was significantly higher, as compared to BA of moderate severity. An IL-4-induced activation of the STAT6 transcription factor was revealed in an in vitro system, being mostly expressed in allergic BA. The level of STAT6 may serve as a BA severity index.

    We present a visualization pipeline from sample to answer for point-of-care blood cell counting applications. Effective and low-cost point-of-care medical diagnostic tests provide developing countries and rural communities with accessible healthcare solutions [1], and can be particularly beneficial for blood cell count tests, which are often the starting point in the process of diagnosing a patient [2]. The initial focus of this work is on total white and red blood cell counts, using a microfluidic cartridge [3] for sample processing. Analysis of the processed samples has been implemented by means of two main optical visualization systems developed in-house: 1) a fluidic operation analysis system using high speed video data to determine volumes, mixing efficiency and flow rates, and 2) a microscopy analysis system to investigate homogeneity and concentration of blood cells. Fluidic parameters were derived from the optical flow [4] as well as color-based segmentation of the different fluids using a hue-saturation-value (HSV) color space. Cell count estimates were obtained using automated microscopy analysis and were compared to a widely accepted manual method for cell counting using a hemocytometer [5]. The results using the first iteration microfluidic device [3] showed that the most simple - and thus low-cost - approach for microfluidic component implementation was not adequate as compared to techniques based on manual cell counting principles. An improved microfluidic design has been developed to incorporate enhanced mixing and metering components, which together with this work provides the foundation on which to successfully implement automated, rapid and low-cost blood cell counting tests.

    This paper aims at providing a scientific basis for unifying the normal reference value standards of red blood cell count of Chinese presenile men. The paper, using microscopical counting method, studies the relationship between the normal reference values of 38,061 samples of red blood cell count ofpresenile men and eight geographical factors in297 units in China. It is found that the correlation of geographical factors and the normal reference value of red blood cell count of presenile men is quite significant (F=303.00, P=0.000). By using the method of stepwise regression analysis,one regression equation is inferred. It is concluded that if geographical data are obtained in a certain area, the normal reference value of red blood cell count of presenile men in this area can be reckoned by using the regression analysis.Furthermore, according to the geographical factors, China can be divided into eight regions: Northeast China Region,North China Region, Shanxi-Shaanxi-Inner Mongolia Region, Middle and Lower Reaches of the Changjiang River Region, Southeast China Region, Northwest China Region, Southwest China Region and Qinghai-Tibet Plateau Region.

    The aim of cardiovascular disease treatment is to reduce the risk of thrombogenesis and improve tissue perfusion, depending inter alia on the rheological properties of the blood. The reduction in blood viscosity and erythrocyte aggregation, as well as increase of erythrocyte deformability was observed under the influence of physical training. To compare the blood count and rheological properties of blood samples before and after outpatient cardiac rehabilitation programme. 35 men (average age: 57.2 ± 5.42), who after suffering myocardial infarction treated with percutaneous coronary intervention (PCI), took part in 24 physical training sessions of moderate intensity (40-60% of heart rate reserve). The standard ergometer submaximal (up to 85% of predicted HRmax) exercise test and echocardiography was performed before and after training. Blood count, fibrinogen concentration as well as aggregation and elongation properties of erythrocytes were analyzed too. Patients significantly increased exercise capacity (p rheology and blood count have been found in patients after myocardial infarction who took part in the physical training sessions of moderate intensity.

    Full Text Available The research goal is to develop an algorithm for the processing of photo images of native blood samples to determine the concentration of erythrocytes, leukocytes and platelets without individual separate preparation of cell samples. Materials and Methods. The objects of investigation were the samples of the whole donated blood, diluted 400 times by saline. Special "photo templates", the effect of "highlighting" of leukocytes, which was detect by authors, and the resolution of platelets from leukocytes by the areas of their photo images were suggested for identification of the cells. Results. 80 photo images of native blood solutions were selected for computer processing, while the total number of cells counted was: erythrocytes — 4184, platelets — 292 and leukocytes — 84, total — 4560 blood cells. Comparison of the results achieved with ones obtained by "manual" account or by the device for formed elements counting Sysmex XT-400i gives satisfactory results. Conclusion. It is shown that the accuracy of counting of the native blood cells may be comparable with the accuracy of similar studies by means of smears. At the same time the proposed analysis of native blood simplifies greatly the samples preparation in comparison to smears, permits to move from the detection of blood cells ratios to the determination of their concentrations in the sample.

    In studying the late health effects of atomic-bomb (A-bomb) survivors, earlier findings were that white blood cell (WBC) count increased with radiation dose in cross-sectional studies. However, a persistent effect of radiation on WBC count and other risk factors has yet to be confirmed. The objectives of the present study were 1) to examine the longitudinal relationship between A-bomb radiation dose and WBC and differential WBC counts among A-bomb survivors and 2) to investigate the potential confounding risk factors (such as age at exposure and smoking status) as well as modification of the radiation dose-response. A total of 7,562 A-bomb survivors in Hiroshima and Nagasaki were included in this study from 1964-2004. A linear mixed model was applied using the repeated WBC measurements. During the study period, a secular downward trend of WBC count was observed. Radiation exposure was a significant risk factor for elevated WBC and differential WBC counts over time. A significant increase of WBC counts among survivors with high radiation dose (> 2 Gy) was detected in men exposed below the age of 20 and in women regardless of age at exposure. Effects on WBC of low dose radiation remain unclear, however. Cigarette smoking produced the most pronounced effect on WBC counts and its impact was much larger than that of radiation exposure.

    1999-11-01

    A new non-flowing laser light scattering method for counting and classifying blood cells is presented. A linear charge- coupled device with 1024 elements is used to detect the scattered light intensity distribution of the blood cells. A pinhole plate is combined with the CCD to compete the focusing of the measurement system. An isotropic sphere is used to simulate the blood cell. Mie theory is used to describe the scattering of blood cells. In order to inverse the size distribution of blood cells from their scattered light intensity distribution, Powell method combined with precision punishment method is used as a dependent model method for measurement red blood cells and blood plates. Non-negative constraint least square method combined with Powell method and precision punishment method is used as an independent model for measuring white blood cells. The size distributions of white blood cells and red blood cells, and the mean diameter of red blood cells are measured by this method. White blood cells can be divided into three classes: lymphocytes, middle-sized cells and neutrocytes according to their sizes. And the number of blood cells in unit volume can also be measured by the linear dependence of blood cells concentration on scattered light intensity.

  3. Signatures of reproductive events on blood counts and biomarkers of inflammation: Implications for chronic disease risk

    Science.gov (United States)

    2017-01-01

    Whether inflammation mediates how reproductive events affect chronic-disease risk is unclear. We studied inflammatory biomarkers in the context of reproductive events using National Health and Nutrition Examination Survey (NHANES) data. From 15,986 eligible women from the 1999–2011 data cycles, we accessed information on reproductive events, blood counts, C-reactive protein (CRP), and total homocysteine (tHCY). We calculated blood-count ratios including: platelet-lymphocyte (PLR), lymphocyte-monocyte (LMR), platelet-monocyte (PMR), and neutrophil-monocyte (NMR). Using sampling weights per NHANES guidelines, means for counts, ratios, or biomarkers by reproductive events were compared using linear regression. We performed trend tests and calculated p-values with partial sum of squares F-tests. Higher PLR and lower LMR were associated with nulliparity. In postmenopausal women, lower PMR was associated with early age at first birth and higher NMR with later age at and shorter interval since last birth. Lower PNR and higher neutrophils and tHCY were associated with early natural menopause. In all women, the neutrophil count correlated positively with CRP; but, in premenopausal women, correlated inversely with tHCY. Reproductive events leave residual signatures on blood counts and inflammatory biomarkers that could underlie their links to chronic disease risk. PMID:28234958

    2004-01-01

    Measures of parasitemia by intraerythrocytic hematozoan parasites are normally expressed as the number of infected erythrocytes per n erythrocytes and are notoriously tedious and time consuming to measure. We describe a protocol for generating rapid counts of nucleated erythrocytes from digital micrographs of thin blood smears that can be used to estimate intensity of hematozoan infections in nonmammalian vertebrate hosts. This method takes advantage of the bold contrast and relatively uniform size and morphology of erythrocyte nuclei on Giemsa-stained blood smears and uses ImageJ, a java-based image analysis program developed at the U.S. National Institutes of Health and available on the internet, to recognize and count these nuclei. This technique makes feasible rapid and accurate counts of total erythrocytes in large numbers of microscope fields, which can be used in the calculation of peripheral parasitemias in low-intensity infections.

    Recent research has raised doubts regarding the utility of serum white blood cell count (WBC) for diagnosis of periprosthetic joint infection (PJI). As synovial WBC and neutrophil (PMN) percentage have been adopted as accurate markers of PJI, this study investigated the correlation of WBC in serum versus joint fluid and diagnostic value of all WBC levels for failed arthroplasty patients. 153 patients (73 PJI) undergoing revision knee arthroplasty were identified. Weak correlations between joint fluid and serum for WBC (R = 0.19), PMN count (R = 0.31), and lymphocyte count (R = -0.22) were observed. Diagnostic accuracy of PMN (93%) and WBC (93%) synovial count relative to serum was similar to synovial WBC (93%) and PMN% (95%) alone. Serum WBC analysis does little to improve the accurate diagnosis of PJI.

    Light's criteria misclassify a quarter of transudates as exudates. We assessed the influence of red blood cell counts on pleural lactate dehydrogenase (LDH) levels and, thereby, on the specificity of Light's criteria. We retrospectively reviewed 1,312 consecutive patients with pleural effusion, of whom 1,014 were exudates and 298 transudates according to clinical criteria. The relationship between pleural erythrocytes and LDH using simple linear regression analysis, as well as the operating characteristics of Light's criteria, were assessed. Finally, a formula to correct pleural LDH levels, according to the erythrocyte count, was generated. There was a linear relationship between the pleural erythrocyte count and LDH levels (r = 0.44; p exudates. A high pleural erythrocyte count, through its influence on the LDH levels, may lead to a transudate being misclassified as an exudate after applying Light's criteria.

    White blood cell (WBC) count appears to predict total mortality and coronary heart disease (CHD) mortality, but it is unclear to what extent the association reflects confounding by smoking, underlying illness, or comorbid conditions. We used data from the Women's Health Initiative to examine the associations of WBC count with total mortality, CHD mortality, and cancer mortality. WBC count was measured at baseline in 160,117 postmenopausal women and again in year 3 in 74,375 participants. Participants were followed for a mean of 16 years. Cox proportional hazards models were used to estimate the relative mortality hazards associated with deciles of baseline WBC count and of the mean of baseline + year 3 WBC count. High deciles of both baseline and mean WBC count were positively associated with total mortality and CHD mortality, whereas the association with cancer mortality was weaker. The association of WBC count with mortality was independent of smoking and did not appear to be influenced by previous disease history. The potential clinical utility of this common laboratory test in predicting mortality risk warrants further study. © The Author 2017.

    Full Text Available INTRODUCTION Epilepsy is a highly prevalent disease affecting 0.5-1.5% of the world's population. One of the most frequently used antiepileptics are valproates. These medicines show a negative impact on haemostasis and peripheral blood count. OBJECTIVE The objective of the study was to examine the negative impact of valproates on haemostasis and peripheral blood count in children and to analyse whether these disturbances were dependent on the dosage of valproates and drug level in blood. METHOD A two-year research was conducted. The research included: 35 children using valproates, 12 children using the therapy of both valproates and carbamazepine and 30 healthy children. Complete peripheral blood count, screening tests of haemostasis (bleeding time, prothrombin time, prothrombin ratio, activated partial thromboplastin time, fibrinogen and capacity of thrombocyte aggregation research were done in all the children. RESULTS We found significantly more common frequency of leukopenia and neutropenia in children using valproates in comparison with the healthy children group. We also found the more common frequency of eosinophilia in comparison with healthy children. The children with the valproate therapy have lower approximate values of the number of platelets, fibrinogen and platelet aggregation in comparison with healthy children, but they have a higher approximate value of bleeding time and prothrombin time. These disturbances are in correlation with the dosage and the level of the medicine in blood. CONCLUSION Valproates have a negative effect on certain blood count parameters and haemostasis in children. Drug dosage and blood drug level are correlated with their negative impact on haemostasis parameters.

    The avian hemogram is usually performed in veterinary diagnostic laboratories by using manual cell counting techniques and differential counts determined by light microscopy. There is no standard automated technique for avian blood cell count and differentiation to date. These shortcomings in birds are primarily because erythrocytes and thrombocytes are nucleated, which precludes the use of automated analyzers programmed to perform mammal complete blood cell counts. In addition, there is no standard avian antibody panel, which would allow cell differentiation by immunophenotyping across all commonly seen bird species. We report an alternative hematologic approach for quantification and differentiation of avian blood cells by using high-throughput image cytometry on blood smears in psittacine bird species. A pilot study was designed with 70 blood smears of different psittacine bird species stained with a Wright-Giemsa stain. The slides were scanned at 0.23 microm/pixel. The open-source softwares CellProfiler and CellProfiler Analyst were used for analyzing and sorting each cell by image cytometry. A "pipeline" was constructed in the CellProfiler by using different modules to identify and export hundreds of measures per cell for shape, intensity, and texture. Rules for classifying the different blood cell phenotypes were then determined based on these measurements by iterative feedback and machine learning by using CellProfiler Analyst. Although this approach shows promises, avian Leukopet results could not be duplicated when using this technique as is. Further studies and more standardized prospective investigations may be needed to refine the "pipeline" strategy and the machine learning algorithm.

    Full Text Available Background: Pregnancy induced hypertension is one of the most common causes of maternal and neonatal mortality and morbidity. New born delivered to mothers with hypertension are more liable for intrauterine growth retardation and may be delivered prematurely. We aimed to determine the effect of pregnancy-induced hypertension on complete blood count, gestational age and birth weight of newborn. Materials and Methods: This study includes 200 neonates, 100 neonates born to mothers diagnosed as having pregnancy induced hypertension this is considered as the study group and 100 neonates born in the same period to healthy mothers considered as the control group, the study conducted in the neonatal unit of the department of pediatrics and gynecological ward in AL-Imamein Al-Kadhimein Medical city, Iraq, from 1st August 2015 to 30th May 2016. Details of the baby including gender, Apgar score, birth weight and gestational age were recorded and hematological parameters (complete blood count of both babies and mothers have been studied. Results: The study showed the significant difference between the two groups regarding mode of delivery, 94% of mothers in study group delivered by cesarean section while 60% of control group, delivered by cesarean section. There was the significant effect of gestational hypertension on gestational age, birth weight, need for resuscitation, Apgar score, mean WBC count and mean platelet count since (P< 0.05. There were no significant differences between two groups regarding another element of complete blood count. Conclusion: At current study, gestational hypertension affects adversely growth parameter, wellbeing and both WBC and platelet count of a newborn.

    The proportion and potential risk of concomitant spuriously elevated white blood cell count (SEWC) are underestimated in ethylenediaminetetraacetic acid (EDTA)-dependent pseudothrombocytopenia (PTCP). The proportion, kinetics and prevention of SEWC remain poorly understood. A total of 25 patients with EDTA-dependent PTCP were enrolled in this study. With the hematology analyzer Coulter LH 750, we determined the time courses of WBC count, WBC differential and platelet count in EDTA- and sodium citrate-anticoagulated blood, respectively. Blood smears were prepared to inspect the presence of platelet clumps using light microscopy. The effect of automatic instrumental correction on the extent of SEWC was evaluated. The proportion of SEWC was 92% in EDTA-dependent PTCP and 73.9% of SEWCs were within the normal range. The development of SEWC was time-dependent, and neutrophils and lymphocytes were the main subpopulations involved in SEWC. A strong and significant correlation (r = 0.9937, p EDTA were significantly higher than their basal counts, respectively, p 0.05. A high proportion of concomitant SEWCs, which are mainly within normal range, are present in patients with EDTA-dependent PTCP. Proper interpretation of SEWC is crucial to avoid clinic errors. SEWC develops in a time-dependent pattern, although the Coulter LH 750 only partly mitigates the extent of SEWC, sodium citrate is able to effectively prevent SEWC.

    It is desirable in the interest of patient safety that the reporting of laboratory results should be standardized where no valid reason for diversity exists. This study considers the reporting units used for the extended blood cell count and makes a new ICSH recommendation to encourage standardization worldwide. This work is based on a literature review that included the original ICSH recommendations and on data gathered from an international survey of current practice completed by 18 countries worldwide. The survey results show that significant diversity in the use of reporting units for the blood count exists worldwide. The use of either non-SI or other units not recommended by the ICSH in the early 1980s has persisted despite the guidance from that time. The diversity in use of reporting units occurs in three areas: the persistence in use of non-SI units for RBC, WBC and platelet counts, the use of three different units for haemoglobin concentration and the manual reporting of WBC differential, reticulocytes and nucleated RBCs when the latter are available from automated analysis or can be expressed as absolute numbers by calculation. A new recommendation with a rationale for each parameter is made for standardization of the reporting units used for the extended blood count. © 2016 John Wiley & Sons Ltd.

    Background White blood cell count is an independent risk factor for cardiovascular disease. Several lifestyle and metabolic factors such as cigarette smoking and obesity are known to be associated with an elevated white blood cell count. However, the joint effect of cigarette smoking and obesity on white blood cell count has not yet been fully described. Methods We explored the joint effect of cigarette smoking and obesity on white blood cell count using multiple logistic regression analyses after adjusting for confounding variables in a population-based, cross-sectional study of 416,065 Korean adults. Results Cigarette smoking and body mass index have a dose-response relationship with a higher white blood cell count, but no synergistic interaction is observed between them (men, P for interaction=0.797; women, P for interaction=0.311). Cigarette smoking and body mass index might have an additive combination effect on high white blood cell count. Obese male smokers were 2.36 times more likely and obese female smokers 2.35 times more likely to have a high white blood cell count when compared with normal body mass index non-smokers. Conclusion Cigarette smoking and body mass index are independently associated with an elevated white blood cell count in both men and women. PMID:28360982

    This study aimed to investigate whether pregnant women with a normal 28-week gestation platelet count and no high-risk conditions for thrombocytopenia require a pre-epidural platelet count. All 1844 included women (platelet count > 150 × 10(9) /L at 28 weeks' gestation, term singleton birth, no thrombocytopenia risk conditions) had a platelet count > 100 × 10(9) /L prebirth, suggesting low-risk pregnant women do not require pre-epidural full blood count solely to check platelet count.

    In patients with thrombocytopenia, it can be difficult to predict a patient's bleeding risk based on platelet count alone. Platelet reactivity may provide additional information; however, current clinical assays cannot reliably assess platelet function in the setting of thrombocytopenia. New methods to study platelet reactivity in thrombocytopenic samples are needed. In this study, we sought to develop a laboratory model of thrombocytopenia using blood from healthy subjects that preserves the whole blood environment and reproducibly produces samples with a specific platelet count and hematocrit. We compared the activation state of unstimulated and agonist-stimulated platelets in thrombocytopenic samples derived from this method with normocytic controls. Whole blood was diluted with autologous red blood cell concentrate and platelet-poor plasma, which were obtained via centrifugation, in specific ratios to attain a final sample with a predetermined platelet count and hematocrit. P-selectin exposure and GPIIbIIIa activation in unstimulated platelets and platelets stimulated with collagen-related peptide (CRP) or adenosine diphosphate (ADP) in thrombocytopenic samples and the normocytic control from which they were derived were quantified by flow cytometry. Our methodology reliably produced thrombocytopenic samples with a platelet count ≤50,000/μL and an accurately and precisely controlled hematocrit. P-selectin exposure and GPIIbIIIa activation on unstimulated platelets or on ADP- or CRP-stimulated platelets did not differ in thrombocytopenic samples compared to normocytic controls. We describe a new method for creating thrombocytopenic blood that can be used to better understand the contributions of platelet number and function to hemostasis.

    Full Text Available BACKGROUND Prematurity refers to live births before 37 weeks of gestation, wherein the baby is born before the body and its organ systems achieve perfect maturity, and this disorder is still a global problem. The high incidence of prematurity is a problem in developing and also in developed countries. Certain conditions accompanying pregnancies like preeclampsia, infection, and placental insufficiency, may trigger uterine hypoxia, causing premature birth. The placental condition is related to the intra-uterine fetal condition. In prolonged placental hypoxia, there occurs a compensatory mechanism, i.e. an increase in placental angiogenesis. This study aimed to evaluate the effect of hypoxia on fetal blood vessel count as compensatory mechanism for tissue hypoxia. METHODS An observational-analytical cross-sectional design using paraffin blocks of conserved premature placentas, comprising 31 samples of hypoxic premature placentas and 28 samples of non-hypoxic premature placentas, selected using non-random consecutive sampling. The samples were made into slides and stained with hematoxylin-eosin for assessment of histological structure, including fetal blood vessel count and integrity, villus conditions, syncytiotrophoblastic nuclear changes, and syncytiotrophoblastic nuclear aggregation. Mann-Whitney test was used to compare the difference of blood vessel count between groups. RESULTS Assessment of histological structure showed a significant increase in fetal blood vessel count in the hypoxic group [8.00 (5-15] as compared with the non-hypoxic group [7.50 (3-15]. CONCLUSION The hypoxia in premature placentas caused an increase in the number of fetal blood vessels as a form of compensation for disturbed oxygen homeostasis.

    Peripheral blood cell counts are important biomarkers of radiation exposure. In this work, a simplified compartmental modeling approach is applied to simulate the perturbation of the hematopoiesis system in humans after radiation exposure, and HemoDose software is reported to estimate individuals' absorbed doses based on multi-type blood cell counts. Testing with patient data in some historical accidents indicates that either single or serial granulocyte, lymphocyte, leukocyte, and platelet counts after exposure can be robust indicators of the absorbed doses. In addition, such correlation exists not only in the early time window (1 or 2 d) but also in the late phase (up to 4 wk) after exposure, when the four types of cell counts are combined for analysis. These demonstrate the capability of HemoDose as a rapid point-of-care diagnostic or centralized high-throughput assay system for personnel exposed to unintended high doses of radiation, especially in large-scale nuclear/radiological disaster scenarios involving mass casualties.

      levels of IL-2, IL-4, and  IL-10, as compared to control group.  It was found that TNFα concentration is considerably higher in both cohorts of the patients, being 2to 3-fold higher than the levels of this cytokine in control group.  When comparing the cohorts with different  control of the disease course, we have found that TNFα concentration in the cohort with uncontrolled bronchial asthma is statistically higher  than  among  children with  controllable course  of the  disease.  Hence, the  following  parameters may serve as potential markers  of pediatric atopic  bronchial asthma with uncontrolled course:  low levels of total Т lymphocyte numbers in peripheral blood,  and decreased counts  of CD4+, CD8+ cells; IgE hyperproduction; low contents of common IgA, and high concentration of TNFα in peripheral blood serum.

    Full Text Available Background. Delivery of full doses of adjuvant chemotherapy on schedule is key to optimal breast cancer outcomes. Neutropenia is a serious complication of chemotherapy and a common barrier to this goal, leading to dose reductions or delays in treatment. While past research has observed correlations between complete blood count data and neutropenic events, a reliable method of classifying breast cancer patients into low- and high-risk groups remains elusive. Patients and Methods. Thirty-five patients receiving adjuvant chemotherapy for early-stage breast cancer under the care of a single oncologist are examined in this study. FOS-3NN stratifies patient risk based on complete blood count data after the first cycle of treatment. All classifications are independent of breast cancer subtype and clinical markers, with risk level determined by the kinetics of patient blood count response to the first cycle of treatment. Results. In an independent test set of patients unseen by FOS-3NN, 19 out of 21 patients were correctly classified (Fisher’s exact test probability P<0.00023 [2 tailed], Matthews’ correlation coefficient +0.83. Conclusions. We have developed a model that accurately predicts neutropenic events in a population treated with adjuvant chemotherapy in the first cycle of a 6-cycle treatment.

    These experimental studies have investigated the reliability of the peripheral blood leukocyte count to predict whether the leukopenic host can contain or eliminate infection. Additionally, we have investigated the possibility that determination of leukocyte recruitment, supplementary to peripheral blood leukocyte counts, might allow individuals with neutropenia at risk from serious infection to be distinguished with greater certainty. Varying doses of radiation, cyclophosphamide, and methylprednisolone were used to induce distinct levels of leukopenia in rats. Leukocyte recruitment was measured by quantifying the response of neutropenic animals to evocative, subcutaneous stimuli, and the results of this assay were then compared with circulating leukocyte counts in the same individuals. Six models of experimentally induced infection were used to compare circulating and recruitable leukocytes as indicators of the susceptibility of the leukopenic host to infection. Response curves relating leukocyte numbers to host resistance were similar when circulating or recruitable leukocytes were used as an index of defense capability. These findings support the use of peripheral blood leukocyte numbers as an index of resistance to infection in individuals with leukopenia and suggest that functional analyses such as leukocyte recruitment are unlikely to provide additional information.

    Full Text Available Bronchial stents are mostly used as a Palliative relief of symptoms often caused by airway obstruction, It is also used for sealing of stump fistulas after pneumonectomy and dehiscence after bronchoplastic operations. Advances in airway prosthetics have provided a variety of silicone stents, expandable metal stents, and pneumatic dilators, enabling the correction of increasingly complex anatomical problems. Several series have been published describing the application and results of these techniques. This manuscript reviews the historical development of stents, types, indication, outcome, and complications. Alternative therapies for tracheobronchial stenting were also reviewed

    Full Text Available BACKGROUND: Although a number of epidemiological studies, showing incidence and prevalence of atopic dermatitis, were available, scant attention has been paid to the correlation between the parameters of the disease like severity, absolute eosinophil count and IgE level, which has been known to be associated inconsistently. Hence this study was undertaken. METHODS: A total of 102 patients of atopic dermatitis, both children and adults, and 107 age matched controls were studied at the Pediatric Dermatology clinic, Institute of Child Health and department of Dermatology, AMRI-Apollo hospitals, Kolkata. RESULTS: The average age of onset of atopic dermatitis was observed to be 4.55 years. Both the average absolute eosinophil count and IgE levels in patients of atopic dermatitis were significantly higher than that of the controls. Each of these parameters showed significant correlation with severity of the disease and showed a nonhomogeneous distribution reflected by significant association with personal history of bronchial asthma and family history of atopy, when both parents were atopic. CONCLUSIONS: Our study shows that clinical activity of the disease as recorded by the "SCORAD" index can be used as an indicator of the hematological abnormalities as well as to some extent as a prognostic indicator. Family history of atopy correlates with the hematological abnormalities only if both parents are involved and bronchial asthma is the only associated atopic condition which correlates with the parameters of the disease .

    Assessment of platelet count is an important diagnostic parameter in haematology. Automated blood cell counters have largely replaced the manual method. However, all abnormal platelet counts are verified in Leishman's stained peripheral blood smear. Platelets also can be identified in the unstained blood smears. The objective of this study is to compare the unstained peripheral blood smears with the stained smears and determination of the effectiveness of unstained smears in the estimation of platelet count. 250 Venous blood samples sent for blood cell counts were analyzed. Platelets were counted in the unstained smear under 100× objective in 10 fields without placing immersion oil and the average number of platelets was calculated. Same smear was stained by Leishman's stain and platelets were counted under 100× objective after placing a drop of immersion oil. Collected data were analyzed for intra-class correlation coefficient (ICC). ICC showed excellent agreement (ICC > 0.85). The unstained smears were found to be as effective as stained smears for platelet count in most of the cases. However, in case of doubt a stained preparation has to be made to confirm the count. The turnaround time was 3-5 minutes compared to 15-20 minutes by stained smear technique, thus this technique may be used as an initial screening method whenever there is large sample load.

  10. Preoperative White Blood Cell Count and Risk of 30-Day Readmission after Cardiac Surgery

    Directory of Open Access Journals (Sweden)

    Jeremiah R. Brown

    2013-01-01

    Full Text Available Approximately 1 in 5 patients undergoing cardiac surgery are readmitted within 30 days of discharge. Among the primary causes of readmission are infection and disease states susceptible to the inflammatory cascade, such as diabetes, chronic obstructive pulmonary disease, and gastrointestinal complications. Currently, it is not known if a patient’s baseline inflammatory state measured by crude white blood cell (WBC counts could predict 30-day readmission. We collected data from 2,176 consecutive patients who underwent cardiac surgery at seven hospitals. Patient readmission data was abstracted from each hospital. The independent association with preoperative WBC count was determined using logistic regression. There were 259 patients readmitted within 30 days, with a median time of readmission of 9 days (IQR 4–16. Patients with elevated WBC count at baseline (10,000–12,000 and >12,000 mm3 had higher 30-day readmission than those with lower levels of WBC count prior to surgery (15% and 18% compared to 10%–12%, P=0.037. Adjusted odds ratios were 1.42 (0.86, 2.34 for WBC counts 10,000–12,000 and 1.81 (1.03, 3.17 for WBC count > 12,000. We conclude that WBC count measured prior to cardiac surgery as a measure of the patient’s inflammatory state could aid clinicians and continuity of care management teams in identifying patients at heightened risk of 30-day readmission after discharge from cardiac surgery.

    Full Text Available Background. Age-related decrease in bone marrow erythropoietic capacity is often accompanied by the telomere length shortening in peripheral white blood cells. However, limited and conflicting data hamper the conclusive opinion regarding this relationship. Therefore, the aim of this study was to assess an association between telomere length and peripheral blood cell count parameters in the Polish elderly population. Material and Methods. The substudy included 1573 of 4981 subjects aged 65 years or over, participants of the population-based PolSenior study. High-molecular-weight DNA was isolated from blood mononuclear cells. Telomere length (TL was measured by QRT-PCR as abundance of telomere template versus a single gene copy encoding acidic ribosomal phosphoprotein P0. Results. Only white blood count (WBC was significantly different in TL tertile subgroups in all subjects (P=0.02 and in men (P=0.01, but not in women. Merely in men significant but weak positive correlations were found between TL and WBC (r=0.11, P<0.05 and RBC (r=0.08, P<0.05. The multiple regression analysis models confirmed a weak, independent contribution of TL to both RBC and WBC. Conclusions. In the elderly, telomere shortening limits hematopoiesis capacity to a very limited extent.

    Our objective was to develop an effective method to prevent the fall in platelet count for patients with anticoagulant-dependent (AD) pseudothrombocytopenia, a spurious phenomenon due to anticoagulant-induced aggregation of platelets. We report a case of insidious multianticoagulant-dependent pseudothrombocytopenia in which AD pseudothrombocytopenia may be caused by 4 anticoagulants, eg, EDTA, sodium citrate, heparin, and sodium fluoride (NaF). Multianticoagulant-dependent pseudothrombocytopenia was confirmed by finding clumped platelets on microscopic evaluation in 4 anticoagulated blood samples. With this case, we tried a variety of reagents, including aminoglycosides, eg, gentamicin and amikacin, vitamin B(6), and aminophylline to inhibit pseudothrombocytopenia. Except for amikacin, all reagents failed to prevent pseudothrombocytopenia. Microscopic examination of K(2)-EDTA-, heparin-, sodium citrate-, and NaF-anticoagulated blood samples showed massive platelet clumping, but no aggregate was seen in the anticoagulated blood with amikacin. When amikacin was added within 1 hour after blood sample withdrawal, platelet, WBC, and RBC counts and hemoglobin level, mean corpuscular volume, and mean platelet volume remained unchanged for up to 4 hours at room temperature. These findings suggest that amikacin could inhibit and dissociate pseudo platelet aggregation in multianticoagulant-dependent pseudothrombocytopenia and EDTA-induced pseudothrombocytopenia.

    This paper describes a monolithic microfluidic device capable of on-chip sample preparation for both RBC and WBC measurements from whole blood. For the first time, on-chip sample processing (e.g. dilution, lysis, and filtration) and downstream single cell measurement were fully integrated to enable sample preparation and single cell analysis from whole blood on a single device. The device consists of two parallel sub-systems that perform sample processing and electrical measurements for measuring RBC and WBC parameters. The system provides a modular environment capable of handling solutions of various viscosities by adjusting the length of channels and precisely controlling mixing ratios, and features a new 'offset' filter configuration for increased duration of device operation. RBC concentration, mean corpuscular volume (MCV), cell distribution width, WBC concentration and differential are determined by electrical impedance measurement. Experimental characterization of over 100,000 cells from 10 patient blood samples validated the system's capability for performing on-chip raw blood processing and measurement.

    The purpose of this prospective study was to verify the changes in the preoperative and postoperative complete blood counts of patients with surgically treated facial fractures. Fifty consecutive patients with a mean age of 34 years who presented facial fractures and underwent surgical treatment were included. A complete blood count was performed, comprising the red and white blood cell count (cells/μL), hemoglobin (g/dL), and hematocrit (%) levels. These data were obtained preoperatively and postoperatively during a 6-week period. Statistical analyses were performed using the Kruskal-Wallis and Mann-Whitney tests to identify the possible differences among the groups and among the periods of observation using the Friedman and Wilcoxon matched-pairs signed-ranks tests. The most common location of the fractures was the mandible (42.3%), followed by the zygomatic-orbital (36.5%) and associated locations (21.2%). Leukocytosis was associated with neutrophilia in the immediate postoperative period in all of the groups. There were no values below the reference limits of the values of hemoglobin, hematocrit, and erythrocytes, and no values above the reference limits for the remaining white blood cells, although significant differences among periods were observed in most cells, depending on the type of fracture. The primary findings were leukocytosis associated with neutrophilia, verified in the immediate postoperative period in all of the groups, and the influence of the type of fracture on the significant alterations observed among studied periods on the values of hemoglobin, hematocrit, erythrocytes, leukocytes, neutrophils, and lymphocytes.

    Full Text Available BACKGROUND: Walking and cardiovascular mortality are inversely associated in type 2 diabetes, but few studies have objectively measured associations of walking with individual cardiovascular risk factors. Such information would be useful for "dosing" daily steps in clinical practice. This study aimed to quantify decrements in blood pressure and glycated hemoglobin (A1C per 1,000 daily step increments. METHODOLOGY/PRINCIPAL FINDINGS: Two hundred and one subjects with type 2 diabetes underwent assessments of step counts (pedometer-measured, blood pressure, A1C and anthropometric parameters. Due to missing data, the final analysis was conducted on 83 women and 102 men, with a mean age of 60 years. Associations of daily steps with blood pressure and A1C were evaluated using sex-specific multivariate linear regression models (adjusted for age, ethnicity, and BMI. Potential sex differences were confirmed in a combined model (women and men with interaction terms. Mean values for daily steps, blood pressure, A1C and BMI were 5,357 steps/day; 137/80 mm Hg; 7.7% and 30.4 kg/m(2 respectively. A 1,000 daily step increment among women was associated with a -2.6 (95% CI: -4.1 to -1.1 mm Hg change in systolic and a -1.4 (95% CI: -2.2 to -0.6 mm Hg change in diastolic blood pressure. Among men, corresponding changes were -0.7 (95% CI: -2.1 to 0.7 and -0.6 (95% CI: -1.4 to 0.3 mm Hg, respectively. Sex differences were confirmed in combined models. Step counts and A1C did not demonstrate clinically important associations. CONCLUSIONS/SIGNIFICANCE: A 1,000 steps/day increment is associated with important blood pressure decrements among women with type 2 diabetes but the data were inconclusive among men. Targeted "dose increments" of 1,000 steps/day in women may lead to measurable blood pressure reductions. This information may be of potential use in the titration or "dosing" of daily steps. No associations were found between step count increments and A1C.

    Full Text Available The objective of this study was to evaluate the effect of blood and milk zinc concentration on somatic cell count and occurrence of subclinical mastitis cases. The study was performed on thirty Holstein cows approximate same body weight, ages 3 to 5 years, with equally milk production. Blood samples were taken after the morning milking from the caudal vein and milk from all four quarters was taken before morning milking. All samples of blood and milk were taken to determined zinc, using inductively coupled plasma mass spectrometry. 37.67% (11/30 cows have blood serum zinc concentration below 7µmol/l, and 63.33% or 19/30 cows have blood serum zinc concentration higher then 13µmol/l. Also 30% (9/30 cows have somatic cell count lower then 400.000/ml which indicate absence of subclinical mastitis, but 70% (21/30 cows have somatic cell count higher then 400.000/ml which indicate subclinical mastitis. Results indicate that cows with level of zinc in blood serum higher then 13 µmol/l have lower somatic cell count. Cows with lower zinc blood serum concentration then 7 µmol/l have high somatic cell count and high incidence of subclinical mastitis. According to results in this research there is no significant effect of milk serum zinc concentration on somatic cell count in dairy cows.

    Asparaginase, an effective drug in the treatment of childhood acute lymphoblastic leukemia (ALL), has become an important component of most childhood ALL regimens during the remission induction or intensification phases of treatment. The incidence range of asparaginase-associated lipid abnormalities that are seen in children is 67-72%. Lipemia causes erroneous results, which uses photometric methods to analyze blood samples. We describe a case of l-asparaginase-associated severe hyperlipidemia with complete blood count abnormalities. Complete blood count analysis was performed with Beckman COULTER(®) GEN·S™ system, which uses the Coulter Volume, Conductivity, Scatter technology to probe hydrodynamically focused cells. Although an expected significant inaccuracy in hemoglobin determination occurred starting from a lipid value of 3450 mg/dl, we observed that triglyceride level was 1466 mg/dl. Complete blood count analysis revealed that exceptionally high hemoglobin, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration levels vs. discordant with red blood cell count, mean corpuscular volume, and hematocrit levels. Total leukocyte count altered spontaneously in a wide range, and was checked with blood smear. Platelet count was in expected range (Table 1). Thus, we thought it was a laboratory error, and the patient's follow-up especially for red cell parameters was made by red blood cell and hematocrit values.

    There continue to be important concerns about the possibility of the occurrence of acute radiation syndromes following nuclear and radiological terrorism or accidents that may result in mass casualties in densely populated areas. To guide medical personnel in their clinical decisions for effective medical management and treatment of the exposed individuals, biological markers are usually applied to examine radiation induced biological changes to assess the severity of radiation injury to sensitive organ systems. Among these the peripheral blood cell counts are widely used to assess the extent of radiation induced bone marrow injury. This is due to the fact that the hematopoietic system is the most vulnerable part of the human body to radiation damage. Particularly, the lymphocyte, granulocyte, and platelet cells are the most radiosensitive of the blood elements, and monitoring their changes after exposure is regarded as a practical and recommended laboratory test to estimate radiation dose and injury. Based upon years of physiological and pathophysiological investigation of mammalian hematopoietic systems, and rigorous coarse-grained bio-mathematical modeling and validation on species from mouse, to dog, monkey, and human, we have developed a set of software tools Hemodose, which can use single or serial granulocyte, lymphocyte, leukocyte, or platelet counts after exposure to estimate absorbed doses of adult victims very rapidly and accurately. Some patient data from historical accidents are utilized as examples to demonstrate the capabilities of these tools as a rapid point-of-care diagnostic or centralized high-throughput assay system in a large-scale radiological disaster scenario. Most significant to the improvement of national and local preparedness of a potential nuclear/radiological disaster, this HemoDose approach establishes robust correlations between the absorbed doses and victim's various types of blood cell counts not only in the early time window (1

    Diagnosis of MDS has changed during the last years because of the 2008 WHO classification. Complete blood cell count (CBC) is a very important tool both for diagnosis of MDS. The aim of this study was to evaluate if it is possible to use the abnormal signals produced by dysplastic cells to produce a flag "dysplasia" able to identify the patients needing further hematological investigations. The proposed flag has been tested in a large group of patients to evaluate the sensibility and specificity. We create 5 patterns of MDS. Our study demonstrated that the flag "dysplasia" is specific and sensible for MDS.

    Cytology tests, whether performed on body fluids, aspirates, or scrapings are commonly used to detect, diagnose, and monitor a wide variety of health conditions. Complete blood counts (CBCs) quantify the number of red and white blood cells in a blood volume, as well as the different types of white blood cells. There is a critical unmet need for an instrument that can perform CBCs at the point of care (POC), and there is currently no product in the US that can perform this test at the bedside. We have developed a system that is capable of tomographic images with sub-cellular resolution with consumer-grade broadband (LED) sources and CMOS detectors suitable for POC implementation of CBC tests. The systems consists of cascaded static Michelson and Sagnac interferometers that map phase (encoding depth) and a transverse spatial dimension onto a two-dimensional output plane. Our approach requires a 5 microliter sample, can be performed in 5 minutes or less, and does not require staining or other processing as it relies on intrinsic contrast. We will show results directly imaging and differentiating unstained blood cells using supercontinuum fiber lasers and LEDs as sources and CMOS cameras as sensors. We will also lay out the follow up steps needed, including image segmentation, analysis and classification, to verify performance and advance toward CBCs that can be performed bedside and do not require CLIA-certified laboratories.

    Leukopenia is a common manifestation of SLE. Addition of immunosuppressive therapy in a SLE patient who is already leukopenic is a clinical concern. It could worsen leukopenia, increase the risk of infection, or both. The aim of this study was to analyze the immediate effect of mycophenolate mofetil on the white blood cell count and the rate of infection in SLE patients. Two hundred and forty-four patients within the Hopkins Lupus Cohort who were newly started on mycophenolate mofetil were included in the study. The white blood cell count and interval infection history on the day mycophenolate mofetil was started were compared with the white blood cell count and interval infection history at the next visit. The study was based on 244 patients who began taking mycophenolate mofetil in the cohort. The study population included 47 % African Americans, 44 % Caucasians, and 9 % other ethnicities. There was a slight but not statistically significant increase in the white blood cell count (6.63 vs. 7.01), after starting mycophenolate mofetil. Patients with a baseline white blood cell count blood cell count after starting mycophenolate mofetil (2.57 vs. 5.13, P = 0.0047). We also found a statistically significant increase in the risk of bacterial infection (but not viral infection) after starting mycophenolate mofetil (4 vs. 9 %, P = 0.0036). Leukopenia does not worsen with mycophenolate mofetil. However, mycophenolate mofetil appears to slightly increase the rate of bacterial (but not viral) infection.

    Serum ferritin levels as well as blood counts are variously affected in diverse disease conditions, particularly those characterized by inflammation. To evaluate the relationship between serum ferritin levels and blood counts in apparently healthy Nigerian subjects. Five (5ml) of venous blood was collected for full blood count, malaria parasite, serum ferritin and C- reactive protein (CRP) estimation from 88 apparently healthy subjects. Those positive for malaria parasite (on blood film examination) or had elevated serum CRP were excluded. Statistical analysis was performed with SPSS version 16; (SPSS Inc., Chicago IL). Associations were tested between parameters using Pearson's correlation, set at a coefficient of p serum ferritin level were 0.37L/L, 7.10 x 10(9)/L, 246.39 x 10(9)/L and 18.35 ng/ml, respectively. Age of subjects varied significantly with serum ferritin, platelet count and TWBC (p > 0.05). The PCV, platelet count and TWBC varied significantly across the different age groups of the study population (p Serum ferritin level in our apparently healthy subjects is lower than previously reported but did not vary significantly with blood counts.

    The aim of this study was to investigate the clinical and laboratorial characteristics of splenic marginal zone lymphoma (SMZL) with an abnormal complete blood count (CBC). Data of 19 newly diagnosed SMZL patients with abnormal CBC were analyzed retrospectively. Seven patients were diagnosed by using splenic histology, 12 patients who did not undergo splenectomy were diagnosed on the basis of typical clinical presentation and cytologic, immunophenotypic and histologic characteristics of peripheral blood and bone marrow, according to SBLG guidelines. The results showed that leukocytosis (≥ 10.0×10(9)/L) was seen in 5 cases (26.3%); leukocytopenia (complete response was achieved in 9 out of 11 (81.8%) patients. It is concluded that SMZL with abnormal CBC has a higher incidence of cytopenia, bone marrow involvement and autoimmune phenomena. Therapeutic strategies consisting of Rituximab show a better efficacy.

    All types of blood cells are formed by differentiation from a small self-maintaining population of pluri-potential stem cells in the bone marrow. Despite abundant information on the molecular aspects of division, differentiation, commitment and maturation of these cells, comparatively little is known about the dynamics of the system as a whole, and how it works to maintain this complex ``ecology'' in the observed normal ranges throughout life. Here we report unexpected large, scale-free, fluctuations detected from the first long-term analysis of the day-to-day variability of a healthy animal's blood cell counts measured over one thousand days. This scale-invariance cannot be accounted for by current theoretical models, and resembles some of the scenarios described for self-organized criticality.

    Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.

    Sarcopenia is a major determinant of frailty, disability and mortality in the elderly. Whether low-grade inflammation, insulin resistance and vitamin D are independently associated with sarcopenia remains unclear. In our study, sarcopenia was defined as an appendicular skeletal muscle mass divided by height squared (ASM/Ht(2)) that was sarcopenia in Korean elderly men aged more than 65 years was 11.2%. ASM/Ht(2) were positively associated with vitamin D levels, but negatively associated with white blood cell counts and HOMA-IR by multiple regression analysis. After adjustment for covariables, sarcopenia was associated with the highest quartile of WBC counts (OR = 2.93, 95% CI = 1.21-7.14) and the highest quartile of serum vitamin D levels (OR = 0.38, 95% CI = 0.15-0.95). In conclusion, the study findings suggest that higher WBC counts and lower vitamin D levels are independently associated with the presence of sarcopenia in community-dwelling elderly men. They also provide a basis for further studies of the complex immune-endocrine network in sarcopenia.

    The possible role of exposure to radiation as a risk factor for human health has been of increasing public concern in the series of explosions at earthquake damaged nuclear reactors on the Japan. Current events throughout the world underscore the growing threat of different forms of accidental exposure to radiation including nuclear accidents, atomic weapons use and testing, and the side effects of cancer therapy. A large range of dose rates of ionizing radiations could be encountered in accidental radiation situations. Nevertheless, most of the studies related to radiation effects have only examined a high dose rate. In this study, we investigated the blood count and the cytokine levels in the serum of mice exposed to a high or low dose rate of radiation. In this study, the precise molecular mechanism underlying the low dose rate of radiation remains unclear, but differential hematopoietic effects of radiation exposed at a high dose rate versus low dose rate were observed using the number of peripheral blood count and serum cytokines. These data suggest that chronic low dose rate exposure caused a stimulation of heamatopoietic system occurrence, unlike those observed after higher dose rate exposure. Our data suggest that the dose rate, rather than the total dose, may be more critical in causing damage to the cellular hematopoietic compartments of the body.

    Recent studies have shown that there is a relationship between some inflammatory and biochemical markers derived from complete blood count (CBC) such as neutrophil/lymphocyte (N/L) ratio, platelet/lymphocyte (P/L) ratio, platelet distribution width (PDW), red blood cell distribution width (RDW), and coronary artery disease (CAD). The aim of this study was to determine N/L ratio, P/L ratio, PDW values, and RDW values, which are associated with myocardial perfusion in patients diagnosed with CAD. This study included 262 patients (149 with myocardial ischemia/infarction and 113 with normal myocardial perfusion) undergoing myocardial perfusion scintigraphy (MPS) with CBC within 90 days of MPS. Myocardial perfusion parameters such as summed stress score and summed difference score (SDS) were compared with N/L ratio, P/L ratio, PDW values, and RDW values. Neutrophil counts and N/L ratios were significantly higher in patients diagnosed with myocardial ischemia and/or infarct. However, there was no statistically significant relationship between myocardial perfusion abnormalities and P/L ratio, PDW values, and RDW values. This study showed that N/L ratio is related to myocardial ischemia/infarction and correlated to left ventricular ejection fraction (LVEF).

    We have examined the influence of erythrocytes containing inclusion bodies, nucleated red cells or giant platelets on the measurement of reticulocyte count by automated machine, R-1000. Correlation of the reticulocyte count between automated and conventional method was extremely good in the blood containing red cells with Jolly bodies, Pappenheimer bodies or basophilic stippling . However, correlation was poor when the sample contained the nucleated red cells. Reticulocyte count was decreased in the blood with significant amounts of nucleated red cells. Since nucleated red cells themselves are not counted as reticulocytes in the machine, this was considered to be due to increased young reticulocytes which frequently appeared with nucleated red cells. Both cold agglutinated red cells and giant platelets apparently influenced the reticulocyte count by the R-1000. These results suggest that red cells with Jolly bodies, Pappenheimer bodies or basophilic stippling do not influence the automatic counting of reticulocytes. Although nucleated red cells, cold agglutinated red cells and giant platelets affected the reticulocyte count, the machine shows abnormal flags in most of above cases (except highly agglutinated red cells), so that one can recount reticulocytes by conventional method. We conclude the machine can safely count the reticulocytes even in the blood containing abnormal red cells or platelets.

    To explore post-partum white blood cell (WBC) count, and possible factors affecting it. Retrospective cohort analysis of 12 079 healthy women, delivering a singleton term fetus with an uncomplicated course of labor, delivery and puerperium. All women delivered in a single tertiary, university-affiliated medical center from 2009 to 2014. Student's t-test, Mann-Whitney's U-test, χ(2) test and ANOVA were used to compare between variables. Multiple variable analyses was performed to allow adjustment for potential covariates and confounders. The main outcome measures included post-partum WBC count and the difference in the post-partum versus ante-partum WBC count, in association to mode of delivery, type of analgesia, timing of cesarean delivery and perineal trauma. The mean post-partum WBC count was 13.39 ± .24 × 10(9)/L (range 1.20-37.30 × 10(9)/L). There is a significant increase in the WBC after delivery (2.1 9 ± 3.33 × 10(9)/L) with significant differences according to mode of delivery (2.34 ± 3.48, 3.32 ± 3.69 and 1.6 0 ± 2.87 × 10(9)/L for spontaneous, assisted and cesarean deliveries. Multiple variables can affect post-partum leukocytosis, including: age, parity, gestational age, mode of delivery, type of anesthesia, timing of cesarean delivery in relation to labor onset and the extent of perineal trauma. Post-partum leukocytosis is a physiological phenomenon with a wide normal variation and multiple contributing factors. As a single parameter, post-partum leukocytosis should not prompt further work up.

    Atherosclerosis is an inflammatory disease, and several inflammatory biomarkers, such as C-reactive protein, have been used to predict the risk of coronary heart disease. High white blood cell count is a strong and independent predictor of coronary risk in patients of both sexes, with and without coronary heart disease. A high number of white blood cells and their subtypes (for example, neutrophils, monocytes, lymphocytes, and eosinophils) are associated with the presence of coronary heart disease, peripheral arterial disease, and stroke. The coronary heart disease risk ratios associated with a high white blood cell count are comparable to those of other inflammatory markers, including C-reactive protein. In addition, other components of the complete blood count, such as hematocrit and the erythrocyte sedimentation rate, also are associated with coronary heart disease, and the combination of the complete blood count with the white blood cell count can improve our ability to predict coronary heart disease risk. These tests are inexpensive, widely available, and easy to order and interpret. They merit further research.

    We assessed the acute effects of a 1-h exposure to second-hand smoke (SHS) on complete blood count (CBC) markers in a controlled simulated bar/restaurant environment. Nineteen adult never-smokers completed a 1-h .exposure to SHS at bar/restaurant levels, and a 1-h exposure to normal room air. Blood samples were collected at the baseline at 30 min during each exposure, and at 0, 0.5, 1, 2, 3, and 4 h after each exposure. The values of white blood cells (WBC) at 1 h (p = 0.010), 3 h (p = 0.040), and 4 h (p = 0.008) following SHS were significantly increased compared with the baseline values. Also, there was a positive association between the WBC and cotinine levels (r = 0.28, p = 0.007). A 1-h exposure to SHS at bar/restaurant levels significantly increased the WBC for at least 4 h following the exposure time. This effect of SHS on WBC has dose-response characteristics and should be considered to prescribing CBC.

    Increased levels of circulating soluble type of E-selectin (sE-selectin), neutrophil counts and blood pressure are associated with the development of cardiovascular diseases (CVD). In this study, we conducted a cross-sectional study of men who participated in health check-ups, and selected those who were not diagnosed with or being treated for metabolic diseases such as diabetes, hypertension and lipid abnormality according to the health check-ups. We measured their basic clinical parameters including blood pressure and neutrophil count, plasma sE-selectin concentration and lifestyle factors, and assessed their interrelations by multivariate linear regression (MLR) analysis. A total of 351 subjects aged 47.5±8.41 (range, 30-64) y were recruited. Significantly correlated with sE-selectin concentration were neutrophil count, diastolic blood pressure (DBP), and systolic blood pressure (SBP) (Pearson's correlation coefficient, 0.194, 0.220 and 0.175, respectively). MLR analysis showed that sE-selectin concentration was independently positively related with DBP and neutrophil count, whereas neutrophil count was positively associated with sE-selectin concentration but not DBP. DBP, but not SBP, was independently positively correlated with sE-selectin concentration but not neutrophil count. These results indicate that circulating sE-selectin concentration may be a biomarker for indicating subsequent development of metabolic diseases, in particular CVD, from a healthy state.

    The conventional method of estimating parasite densities employ an assumption of 8000 white blood cells (WBCs)/μl. However, due to leucopenia in malaria patients, this number appears to overestimate parasite densities. In this study, we assessed the accuracy of parasite density estimated using this assumed WBC count in eastern Myanmar, where Plasmodium vivax has become increasingly prevalent. From 256 patients with uncomplicated P. vivax malaria, we estimated parasite density and counted WBCs by using an automated blood cell counter. It was found that WBC counts were not significantly different between patients of different gender, axillary temperature, and body mass index levels, whereas they were significantly different between age groups of patients and the time points of measurement. The median parasite densities calculated with the actual WBC counts (1903/μl) and the assumed WBC count of 8000/μl (2570/μl) were significantly different. We demonstrated that using the assumed WBC count of 8000 cells/μl to estimate parasite densities of P. vivax malaria patients in this area would lead to an overestimation. For P. vivax patients aged five years and older, an assumed WBC count of 5500/μl best estimated parasite densities. This study provides more realistic assumed WBC counts for estimating parasite densities in P. vivax patients from low-endemicity areas of Southeast Asia.

    Immune alterations may play a role in bipolar disorder etiology; however, the relationship between overall immune system functioning and mood symptom severity is unknown. The two comparative effectiveness trials, the Clinical and Health Outcomes Initiatives in Comparative Effectiveness for Bipolar Disorder Study (Bipolar CHOICE) and the Lithium Treatment Moderate-Dose Use Study (LiTMUS), were similar trials among patients with bipolar disorder. At study entry, white blood cell count and bipolar mood symptom severity (via Montgomery-Aasberg Depression Rating Scale and Bipolar Inventory of Symptoms Scale) were assessed. We performed analysis of variance and linear regression analyses to investigate relationships between deviations from median white blood cell and multinomial regression analysis between higher and lower white blood cell levels. All analyses were adjusted for age, gender, body mass index, smoking, diabetes, hypertension and hyperlipidemia. Among 482 Bipolar CHOICE participants, for each 1.0 × 10(9)/L white blood cell deviation, the overall Bipolar Inventory of Symptoms Scale severity increased significantly among men (coefficient = 2.13; 95% confidence interval = [0.46, -3.79]; p = 0.013), but not among women (coefficient = 0.87; 95% confidence interval = [-0.87, -2.61]; p = 0.33). Interaction analyses showed a trend toward greater Bipolar Inventory of Symptoms Scale symptom severity among men (coefficient = 1.51; 95% confidence interval = [-0.81, -3.82]; p = 0.2). Among 283 LiTMUS participants, higher deviation from the median white blood cell showed a trend toward higher Montgomery-Aasberg Depression Rating Scale scores among men (coefficient = 1.33; 95% confidence interval = [-0.22, -2.89]; p = 0.09), but not among women (coefficient = 0.34; 95% confidence interval = [-0.64, -1.32]; p = 0.50). When combining LiTMUS and Bipolar CHOICE, Montgomery-Aasberg Depression Rating Scale scores

    In this paper we overview a method to automatically count morphologically normal red blood cells (RBCs) by using off-axis digital holographic microscopy and statistical methods. Three kinds of RBC are used as training and testing data. All of the RBC phase images are obtained with digital holographic microscopy (DHM) that is robust to transparent or semitransparent biological cells. For the determination of morphologically normal RBCs, the RBC's phase images are first segmented with marker-controlled watershed transform algorithm. Multiple features are extracted from the segmented cells. Moreover, the statistical method of Hotelling's T-square test is conducted to show that the 3D features from 3D imaging method can improve the discrimination performance for counting of normal shapes of RBCs. Finally, the classifier is designed by using statistical Bayesian algorithm and the misclassification rates are measured with leave-one-out technique. Experimental results show the feasibility of the classification method for calculating the percentage of each typical normal RBC shape.

    To develop a miniature complete blood count (CBC) analyzer for point-of-care testing (POCT), a MEMS CBC sensor based on the impedance method is discussed. A novel MEMS CBC sensor that is fabricated through a simple photolithography process using SU-8 is realized. However, the fabricated sensor exhibits a noisy output signal due to electrolysis gas. The relationship between the noise and the gas is revealed through microscopic observation and finite element method (FEM) simulation. To solve the problem of electrolysis gas, an improved MEMS CBC sensor with vanes is developed. The improved sensor is unaffected by electrolysis gas. Moreover, the signal stability of the sensor and the signals detected for latex particles are successfully evaluated.

    Combining a polymerase chain reaction (PCR) test with bronchoscopy is frequently performed to allow a rapid diagnosis of smear-negative pulmonary tuberculosis (PTB). However, limited data are available concerning clinical judgment in patients with suspected PTB and AFB smear- and PCR-negative bronchial aspirates (BA). The present study evaluated the usefulness of whole-blood QuantiFERON-TB Gold In-Tube (QFT) testing in these patients. Of 166 patients with suspected PTB who had undergone bronchoscopy because of smear-negative sputum or inadequate sputum production, 93 (56%) were diagnosed with culture-positive PTB. Seventy-four patients were either AFB smear- or PCR-positive. In the 75 patients whose BA AFB smear and PCR results were both negative, 19 were finally diagnosed with PTB by culture. The QFT test had a negative predictive value of 91% for PTB. The QFT test may be useful for excluding PTB in patients with suspected PTB whose BA AFB smear and PCR results are both negative.

    While cigarette smoking is a well-recognized cause of elevated white blood cell (WBC) count, studies on longitudinal effect of smoking cessation on WBC count are limited. We attempted to determine causal relationships between smoking and elevated WBC count by retrospective cross-sectional study consisting of 37,972 healthy Japanese adults who had a health check-up between April 1, 2008 and March 31, 2009 and longitudinal study involving 1730 current smokers who had more than four consecutive annual health check-ups between April 1, 2007 and March 31, 2012. In the cross-sectional study, younger age, male gender, increased body mass index, no alcohol habit, current smoking, and elevated C-reactive protein level were associated with elevated WBC count. Among these factors, current smoking had the most significant association with elevated WBC count. In subgroup analyses by WBC differentials, smoking was significantly associated with elevated counts of neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Ex-smoking was not associated with elevated WBC count. In the longitudinal study, both WBC and neutrophil counts decreased significantly in one year after smoking cessation and remained down-regulated for longer than next two years. There was no significant change in either WBC or neutrophil count in those who continued smoking. These findings clearly demonstrated that current smoking is strongly associated with elevated WBC count and smoking cessation leads to recovery of WBC count in one year, which is maintained for longer than subsequent two years. Thus, current smoking is a significant and reversible cause of elevated WBC count in healthy adults.

    Bronchial asthma is a heterogeneous disease that includes various subtypes. They may share similar clinical characteristics, but probably have different pathological mechanisms. To identify phenotypes using cluster analysis in moderate to severe bronchial asthma and to compare differences in clinical, physiological, immunological and inflammatory data between the clusters. Forty adult patients with moderate to severe bronchial asthma out of exacerbation were included. All underwent clinical assessment, anthropometric measurements, skin prick testing, standard spirometry and measurement fraction of exhaled nitric oxide. Blood eosinophilic count, serum total IgE and periostin levels were determined. Two-step cluster approach, hierarchical clustering method and k-mean analysis were used for identification of the clusters. We have identified four clusters. Cluster 1 (n=14) - late-onset, non-atopic asthma with impaired lung function, Cluster 2 (n=13) - late-onset, atopic asthma, Cluster 3 (n=6) - late-onset, aspirin sensitivity, eosinophilic asthma, and Cluster 4 (n=7) - early-onset, atopic asthma. Our study is the first in Bulgaria in which cluster analysis is applied to asthmatic patients. We identified four clusters. The variables with greatest force for differentiation in our study were: age of asthma onset, duration of diseases, atopy, smoking, blood eosinophils, nonsteroidal anti-inflammatory drugs hypersensitivity, baseline FEV1/FVC and symptoms severity. Our results support the concept of heterogeneity of bronchial asthma and demonstrate that cluster analysis can be an useful tool for phenotyping of disease and personalized approach to the treatment of patients.

This means that the condition of individuals must be related to or compared with reference data. Determination of a reference range for the healthy term newborn is clinically important in terms of various complete blood count parameters. The purpose of this study was to establish a local reference range for full blood count parameters in neonatal cord plasma in Hilla, Babil, Iraq.Methods: A total of 220 mothers and their neonates were enrolled in this cross-sectional study from February 2011 to January 2012. Maternal inclusion criteria were age 15–45 years, an uneventful pregnancy, and hemoglobin ≥ 10 g. Neonatal inclusion criteria were full term (37–42 weeks and normal birth weight. The umbilical cord was immediately clamped after delivery of the baby; 3 mL of cord blood was then taken from the umbilical vein and collected in a tube containing ethylenediamine tetra-acetic acid, its plasma was analyzed for full blood count parameters by standard Coulter gram, and the differential leukocyte count was done manually.Results: Mean neonatal hemoglobin was 13.88 ± 1.34 (range 11–17.3 g/dL and mean white cell count was 10.12 ± 2.8 (range 3.1–21.6 × 109/L. Mean platelet count was 267.63 ± 60.62 (range 152–472 × 109/L. No significant differences in red cell, white cell, or platelet counts were found between males and females, except for neutrophil count. The current study shows lower levels of hemoglobin, white cells, and red cells compared with other studies, and there is agreement with some studies and disagreement with others concerning platelet count.Conclusion: Most results

    The diagnosis of myelodysplastic syndromes (MDS) requires a high clinical index of suspicion to prompt bone marrow studies as well as subjective assessment of dysplastic morphology. We sought to determine if data collected by automated hematology analyzers during complete blood count (CBC) analysis might help to identify MDS in a routine clinical setting. We collected CBC parameters (including those for research use only and cell population data) and demographic information in a large (>5,000), unselected sequential cohort of outpatients. The cohort was divided into independent training and test groups to develop and validate a random forest classifier that identifies MDS. The classifier effectively identified MDS and had a receiver operating characteristic area under the curve (AUC) of 0.942. Platelet distribution width and the standard deviation of red blood cell distribution width were the most discriminating variables within the classifier. Additionally, a similar classifier was validated with an additional, independent set of >200 patients from a second institution with an AUC of 0.93. This retrospective study demonstrates the feasibility of identifying MDS in an unselected outpatient population using data routinely collected during CBC analysis with a classifier that has been validated using two independent data sets from different institutions.

    Exercise, even though it has a beneficial effect, can cause muscle damage and trigger inflammatory responses, as evidenced by increased neutrophils in the blood. Acupuncture is a therapeutic modality that is expected to reduce acute inflammatory responses due to exercise. Thirty untrained men were divided randomly into two groups. The manual acupuncture group (n = 15) received stimulation at acupoints ST36 and SP6 bilateral by needle insertion, while the placebo group (n = 15) received insertion of needles on plaster without penetrating the skin. Therapy was done once for 30 minutes immediately after the subjects completed the exercise. Blood neutrophil counts were assessed before exercise and one hour after exercise ended. The results show there is a statistically significant difference in the number of neutrophils before and after exercise between the manual acupuncture group and the placebo group (0.08±0.91 and 0.97±0.70 p = 0.006). Acupuncture therapy effectively mitigates the acute inflammatory response triggered by exercise.

    The objectives of this study were to describe and relate perioperative changes in blood leukocyte counts to the outcome of surgical colic horses, determine a cut-off value in the early postoperative period to obtain an indicator of the outcome, and compare the obtained value to a validation population of horses. Fifty-three horses undergoing colic surgery were included in the descriptive part of the study. Total leukocyte counts were performed before, during and serially after surgery. A receiver operating characteristic analysis was performed on the leukocyte counts of 45 of these horses to determine a cut-off value for the outcome. The results obtained were validated on a second set of 50 horses that underwent colic surgery in similar conditions. The kinetics of blood leukocytes in survivors was higher than in non-survivors during the first days. Non-survivor horses were more likely to have at least one blood leukocyte count ≤ 3.9 × 10(3)/mm(3) between 28 and 60 hours after surgery than survivor horses. This cut-off value was confirmed in the validation population. These results suggest that routine values of blood leukocyte counts can be used as an additional prognostic indicator after colic surgery alongside other predictors previously associated with the outcome.

    Therapeutic decisions regarding urinalysis are commonly based on the presence of white and red blood cells. Traditionally, numbers per high-power field are estimated using wet-mount microscopic examination. This technique is not standardized and counts are likely prone to inaccuracy. In addition, differentiation of leukocyte types is not possible. The aims of this study were to (1) compare WBC and RBC estimates using wet-mount examination with counts obtained using a hemocytometer, (2) assess if a hematology automated analyzer (Sysmex ST-2000iV/XT) provides reliable WBC and RBC counts in urine comparable to hemocytometer counts, and (3) evaluate air-dried Wright-Giemsa-stained urine drop sediment preparations for the determination of differential leukocyte counts. WBC and RBC counts were obtained by performing wet-mount estimates, manual hemocytometer counts, and Sysmex automated counts on 219 canine and feline urine samples. Results were correlated using Spearman rank correlation. Air-dried Wright-Giemsa stained sediment drop preparations (n = 215) were examined for differential counts of leukocytes. A low but significant association was found between WBC estimates on wet-mount examination and hemocytometer counts (rho = 0.37, P < .01). There was a high and significant association when RBC counts were compared between wet-mount and hemocytometer evaluation (rho = 0.7, P < .01). There was very high and significant interassay correlation between Sysmex data from duplicate samples for what the analyzer classified as WBC (rho = 0.97, P < .01) and RBC (rho = 0.94, P < .01). Low correlations were found between the Sysmex RBC counts and both wet-mount estimates and hemocytometer RBC counts (rho = 0.43, P < .01 and rho = 0.39, P < .01, respectively). Cell preservation in the air-dried sediment preparations was so poor that differential counts could not be performed. WBC and RBC estimates on wet-mount examination agreed with hemocytometer counts and are therefore

    Full Text Available Abstract Background Mammalian cells transform into individual tubular straw cells naturally in tissues and in response to desiccation related stress in vitro. The transformation event is characterized by a dramatic cellular deformation process which includes: condensation of certain cellular materials into a much smaller tubular structure, synthesis of a tubular wall and growth of filamentous extensions. This study continues the characterization of straw cells in blood, as well as the mechanisms of tubular transformation in response to stress; with specific emphasis placed on investigating whether tubular transformation shares the same signaling pathway as apoptosis. Results There are approximately 100 billion, unconventional, tubular straw cells in human blood at any given time. The straw blood cell count (SBC is 45 million/ml, which accounts for 6.9% of the bloods dry weight. Straw cells originating from the lungs, liver and lymphocytes have varying nodules, hairiness and dimensions. Lipid profiling reveals severe disruption of the plasma membrane in CACO cells during transformation. The growth rates for the elongation of filaments and enlargement of rabbit straw cells is 0.6~1.1 (μm/hr and 3.8 (μm3/hr, respectively. Studies using apoptosis inhibitors and a tubular transformation inhibitor in CACO2 cells and in mice suggested apoptosis produced apoptotic bodies are mediated differently than tubular transformation produced straw cells. A single dose of 0.01 mg/kg/day of p38 MAPK inhibitor in wild type mice results in a 30% reduction in the SBC. In 9 domestic animals SBC appears to correlate inversely with an animal's average lifespan (R2 = 0.7. Conclusion Straw cells are observed residing in the mammalian blood with large quantities. Production of SBC appears to be constant for a given animal and may involve a stress-inducible protein kinase (P38 MAPK. Tubular transformation is a programmed cell survival process that diverges from apoptosis

However, few studies have evaluated the association of RBC count with microvascular complications in patients with type 2 diabetes mellitus (T2DM. The purpose of this study was to investigate the association of RBC count with microvascular complications in patients with T2DM.Methods: This study involved 369 patients with T2DM: 243 with one or more microvascular complications and 126 without microvascular complications. Anticoagulated blood was collected and analyzed in an automated blood cell counter. The presence of risk factors for microvascular complications was determined.Results: The proportion of patients with microvascular complications increased as the RBC count decreased (P < 0.001. After adjustment for known risk factors for microvascular complications by logistic regression analysis, lower quartiles of RBC count were associated with a higher risk of microvascular complications compared with the reference group composed of the highest quartile (first quartile, odds ratio 4.98, 95% confidence interval 1.54–6.19, P = 0.008; second quartile, odds ratio 3.21, 95% confidence interval 1.17–5.28, P = 0.024.Conclusion: A decreased RBC count is associated with microvascular complications in Chinese patients with T2DM.

    2016-10-01

    Full Text Available Introduction: In order to carry out an autologous transplantation, hematopoietic stem cells should be mobilized to peripheral blood and later collected by apheresis. The CD34+ cell count is a tool to establish the optimal time to begin the apheresis procedure. Objective: To evaluate the association between peripheral blood CD34+ cell count and the successful collection of hematopoietic stem cells. Materials and methods: A predictive test evaluation study was carried out to establish the usefulness of peripheral blood CD34+ cell count as a predictor of successful stem cell collection in patients that will receive an autologous transplantation. Results: 77 patients were included (median age: 49 years; range: 5-66. The predominant baseline diagnosis was lymphoma (53.2 %. The percentage of patients with successful harvest of hematopoietic stem cells was proportional to the number of CD34+cells in peripheral blood at the end of the mobilization procedure. We propose that more than 15 CD34+cells/μL must be present in order to achieve an adequate collection of hematopoietic stem cells. Conclusion: Peripheral blood CD34+ cell count is a useful tool to predict the successful collection of hematopoietic stem cells.

    Introduction It is well known that the efficacy of intravenous (IV) tissue plasminogen activator (tPA) is time-dependent when used to treat patients with acute ischemic strokes. Aim Our study examines the safety issue of giving IV tPA without complete blood count (CBC) resulted. Materials and Methods This is a retrospective observational study by examining the database from Huashan Hospital in China and OSF/INI Comprehensive Stroke Center in United States. Patient data collected included demographics, occurrence of symptomatic intracranial hemorrhage, door to needle intervals, National Institute of Health Stroke Scale scores on admission, CBC results on admission and follow-up modified Rankin Scale scores. Linear regression and multivariable logistic regression analysis were used to identify factors that would have an impact on door-to-needle intervals. Results Our study included120 patients from Huashan Hospital and 123 patients from INI. Among them, 36 in Huashan Hospital and 51in INI received IV tPA prior to their CBC resulted. Normal platelet count was found in 98.8% patients after tPA was given. One patient had thrombocytopenia but no hemorrhagic event. A significantly shorter door to needle interval (DTN) was found in the group without CBC resulted. There was also a difference in treatment interval between the two hospitals. Door to needle intervals had a strong correlation to onset to treatment intervals and NIHSS scores on admission. Conclusion In patients presented with acute ischemic stroke, the risk of developing hemorrhagic event is low if IV tPA is given before CBC has resulted. The door to needle intervals can be significantly reduced. PMID:26147994

    Full Text Available Introduction: Increased numbers of nucleated red blood cells (NRBC circulating in the blood of neonates can be associated with relative hypoxia and adverse outcomes. Thus, the aim of this study was to assess the NRBC count during the first week of life in neonates diagnosed with asphyxia as compared to healthy neonates and to determine the short-term morbidity and mortality for the affected babies. Methods: The cross-sectional study compared 15 healthy neonates with 15 neonates diagnosed with asphyxia confirmed by pH of cord blood or Apgar scores. The nucleated red blood cell (NRBC counts were calculated right after birth, and on days 3 and 7, and the hematological parameters of umbilical cord blood were also evaluated. The infants were followed for mortality and associated morbidity. Statistical analysis was conducted using the Mann-Whitney U test, analysis of variance, chi-square tests, and Pearson’s correlation coefficient. A p-value < 0.05 was considered as statistically significant. Results: The initial NRBC counts were significantly higher in the asphyxiated group than in the control group and the difference remained significant through the end of first week. All of the umbilical cord blood parameters were significantly lower in the study group and were negatively correlated with the NRBC count. At birth, higher NRBC count correlated with higher mortality. conclution: Results show that NRBC count is a useful predictive factor for neonatal asphyxia through the end of the first week of life, although a larger study population and a longer follow up period seems to be necessary.

    Sepsis is a serious disease condition and a major cause of intensive care unit (ICU) admission. Its diagnosis in critically ill patients is complicated. To diagnose an infection rapidly, and to accurately differentiate systemic inflammatory response syndrome (SIRS) from sepsis, is challenging yet early diagnosis is vital for early induction of an appropriate therapy. The aim of this study was to evaluate whether the immature granulocyte (IG) count is a useful early diagnostic marker of sepsis compared to other markers. Therefore, a total of 70 consecutive surgical intensive care patients were assessed. IGs were measured from whole blood samples using an automated analyzer. C-reactive protein (CRP), lipopolysaccharide binding protein (LBP) and interleukin-6 (IL-6) concentrations were also determined. The observation period was a maximum of 21 days and ended with the patients' discharge from ICU or death. Receiver operating characteristic (ROC) analyses were conducted and area under the curve (AUC) was calculated to determine sensitivities and specificities for the parameters. We found that the IG count significantly discriminates between infected and non-infected patients (P SIRS onset. Regarding the discriminative power for infection, the IG count was more indicative than other clinical parameters such as CRP, LBP and IL-6, which had a sensitivity of less than 68%. Additionally, the highest diagnostic odds ratio (DOR) with 26.7 was calculated for the IG count within the first 48 hours. During the course of the disease ROC curve analyses showed a superior positive predictive value of the IG count compared to the other measured parameters during the first five days following the fulfillment of SIRS criteria. However, the number of IGs was not correlated with ICU mortality. The total number of IG in peripheral blood from ICU patients is a good marker to discriminate infected and non-infected patients very early during SIRS. However, the IG count is not suitable

    - A novel automated slide-based approach to the complete blood count and white blood cell differential count is introduced. - To present proof of concept for an image-based approach to complete blood count, based on a new slide preparation technique. A preliminary data comparison with the current flow-based technology is shown. - A prototype instrument uses a proprietary method and technology to deposit a precise volume of undiluted peripheral whole blood in a monolayer onto a glass microscope slide so that every cell can be distinguished, counted, and imaged. The slide is stained, and then multispectral image analysis is used to measure the complete blood count parameters. Images from a 600-cell white blood cell differential count, as well as 5000 red blood cells and a variable number of platelets, that are present in 600 high-power fields are made available for a technologist to view on a computer screen. An initial comparison of the basic complete blood count parameters was performed, comparing 1857 specimens on both the new instrument and a flow-based hematology analyzer. - Excellent correlations were obtained between the prototype instrument and a flow-based system. The primary parameters of white blood cell, red blood cell, and platelet counts resulted in correlation coefficients (r) of 0.99, 0.99, and 0.98, respectively. Other indices included hemoglobin (r = 0.99), hematocrit (r = 0.99), mean cellular volume (r = 0.90), mean corpuscular hemoglobin (r = 0.97), and mean platelet volume (r = 0.87). For the automated white blood cell differential counts, r values were calculated for neutrophils (r = 0.98), lymphocytes (r = 0.97), monocytes (r = 0.76), eosinophils (r = 0.96), and basophils (r = 0.63). - Quantitative results for components of the complete blood count and automated white blood cell differential count can be developed by image analysis of a monolayer preparation of a known volume of peripheral blood.

    Full Text Available Colorectal cancer (CRC is the third most common malignancy in males and the second most common in females worldwide. Distant metastases have a strong negative impact on the prognosis of CRC patients. The most common site of CRC metastases is the liver. Both disease progression and metastasis have been related to the patient's peripheral blood monocyte count. We therefore performed a case-control study to assess the relationship between the preoperative peripheral blood monocyte count and colorectal liver metastases (CRLM.Clinical data from 117 patients with colon cancer and 93 with rectal cancer who were admitted to the Chinese People's Liberation Army General Hospital (Beijing, China between December 2003 and May 2015 were analysed retrospectively, with the permission of both the patients and the hospital.Preoperative peripheral blood monocyte counts, the T and N classifications of the primary tumour and its primary site differed significantly between the two groups (P 0.505 × 109 cells/L, high T classification and liver metastasis were independent risk factors for 5-year OS (RR: 2.737, 95% CI: 1.573~ 4.764, P <0.001; RR: 2.687, 95%CI: 1.498~4.820, P = 0.001; RR: 4.928, 95%CI: 2.871~8.457, P < 0.001.The demonstrated association between preoperative peripheral blood monocyte count and liver metastasis in patients with CRC recommends the former as a useful predictor of postoperative prognosis in CRC patients.

    Background & aims Red blood cell (RBC) indices have been demonstrated to be associated with fatty liver disease (FLD) and metabolic syndrome. However, controversy exists regarding the relationship of RBC indices with FLD to date and few has focused on RBC count. This study aimed to explore the association between RBC count and risk of FLD in Southern Chinese adults. Methods A hospital-based cross-sectional study was performed in two hospital health examination centers, including information on ultrasonography-diagnosed FLD, anthropometric indices and biochemical measurements. Covariance analysis was used to evaluate group differences. After quintile classification of RBC counts, logistic regression analysis was conducted to evaluate the odds ratios (ORs) of FLD. Results This study consisted of 8618 subjects (4137 men and 4481 women) aged between 20 and 89 years. FLD cases had higher RBC counts than non-FLD cases in both genders (Pwomen. Binary logistic regression analysis showed positive association between RBC count and FLD, and the OR (95% confidence interval (CI)) were 2.56 (2.06–3.18) in men and 3.69 (2.74–4.98) in women, respectively, when comparing Q5 with Q1. Stratified analyses showed similar trends among subjects with and without FLD risk factors. Gender independent results were similar to gender dependent results. Conclusions Elevated RBC count is independently associated with high risk of FLD, suggesting that the RBC count may be a potential risk predictor for FLD. PMID:28187211

    Platelets play a crucial role in hemostasis. Their activation has not yet been evaluated in healthy dogs with a normal and low platelet count. The aim of this study was to determine the influence of activators on platelet activation in dogs with a normal platelet count and asymptomatic thrombocytopenia. 72 clinically healthy dogs were enrolled. Patients were allocated into three groups. Group 1 consisted of 30 dogs with a normal platelet count, group 2 included 22 dogs with a platelet count between 100 and 200×109/l and group 3 consisted of 20 dogs with a platelet count lower than 100×109/l. Platelet rich-plasma (PRP) was obtained from peripheral blood samples using tripotassium ethylenediaminetetraacetic acid (K3-EDTA) as anticoagulant. Next, platelets were stimulated using phorbol-12-myristate-13-acetate or thrombin, stabilized using procaine or left unstimulated. The expression of CD51 and CD41/CD61 was evaluated. Co-expression of CD41/CD61 and Annexin V served as a marker of platelet activation. The expression of CD41/CD61 and CD51 did not differ between the 3 groups. Thrombin-stimulated platelets had a significantly higher activity in dogs with a normal platelet count than in dogs with asymptomatic thrombocytopenia. Procaine inhibited platelet activity in all groups. In conclusion, activation of platelets of healthy dogs in vitro varied depending on the platelet count and platelet activator.

    Analysis of the association between antibodies against bovine leukemia virus (BLV), BLV proviral load, and white blood cell (WBC) and lymphocyte counts was performed with 774 dairy cows. The average age, WBC counts and lymphoid cell counts tended to be higher in BLV antibody-positive cows than in antibody-negative cows. There was a similar trend in levels of proviral DNA. We analyzed age, WBC counts and lymphocyte counts by principal component analyses to create a distribution chart of the principle component scores. Using the chart, we categorized cows into four quadrants based on additional information, such as the presence of antibody and the levels of proviral DNA. Antibody-positive cows and cows with high BLV proviral load were found mostly in one quadrant of the chart, indicating that it is possible to predict the risk of infection without any knowledge on antibody status by using information, such as WBC counts as a biomarker. When only antibody-positive cows were included in the analysis, a characteristic distribution of different levels of proviral DNA was seen in the quadrants, suggesting that it is possible to estimate the extent of bovine leukosis infection by using this analysis. For this analysis and categorization of the cows into quadrants, we computed a mathematical formulation using discriminant analysis based on age and WBC and lymphocyte counts. This mathematical formulation for the hematological preliminary diagnosis of the disease is recommended as a screening tool to monitor bovine leukosis. PMID:27064146

    Leukocytes normally marginate toward the vascular wall in large vessels and within the microvasculature. Reversal of this process, leukocyte demargination, leads to substantial increases in the clinical white blood cell and granulocyte count and is a well-documented effect of glucocorticoid and catecholamine hormones, although the underlying mechanisms remain unclear. Here we show that alterations in granulocyte mechanical properties are the driving force behind glucocorticoid- and catecholamine-induced demargination. First, we found that the proportions of granulocytes from healthy human subjects that traversed and demarginated from microfluidic models of capillary beds and veins, respectively, increased after the subjects ingested glucocorticoids. Also, we show that glucocorticoid and catecholamine exposure reorganizes cellular cortical actin, significantly reducing granulocyte stiffness, as measured with atomic force microscopy. Furthermore, using simple kinetic theory computational modeling, we found that this reduction in stiffness alone is sufficient to cause granulocyte demargination. Taken together, our findings reveal a biomechanical answer to an old hematologic question regarding how glucocorticoids and catecholamines cause leukocyte demargination. In addition, in a broader sense, we have discovered a temporally and energetically efficient mechanism in which the innate immune system can simply alter leukocyte stiffness to fine tune margination/demargination and therefore leukocyte trafficking in general. These observations have broad clinically relevant implications for the inflammatory process overall as well as hematopoietic stem cell mobilization and homing.

  10. Auto-validation of complete blood counts in an outpatient's regional laboratory.

    The rate of auto-validation is dependent on the ability of the laboratory information system (LIS) to integrate historical data, on the frequency and methods for identifying analyzer errors, and on the criteria for reflex testing, including the need for peripheral smear review. The rate of auto-validation in outpatient laboratories, however, is unclear. We examined 45,925 consecutive complete blood count (CBC) test results (1 January, 2014-31 January, 2014) from patients aged 50±24 years. The LIS auto-validates all samples according to set criteria. Technicians validated test results when previous CBC test results were required to determine: 1) the need for peripheral slide review and/or sample rerun or 2) the need for reflex testing to detect autoimmune hemolytic anemia or β-thalassemia minor. The auto-validation rates were 97.6% after rejecting results requiring validation to determine the need for a peripheral smear review and/or sample rerun. This decreased to 92.9% after including reflex testing to determine the reasons for normocytic and microcytic anemia. We estimated that auto-validation decreased the workload by 7.7-11.6 h per 3000 test results. We conclude that very high auto-validation rates are possible in outpatient general laboratories, leading to conformity in the validation process and a considerable estimated savings in technician time. Further studies are needed in other settings.

    This study presents the results of an aging stability study of complete blood count (CBC) and leukocyte differential parameters using the Abbott CELL-DYN Sapphire hematology analyzer. Stability studies showed no substantial change in CBC parameters up to 24-48 h at +23 +/- 2 degrees C (room temperature), except for optical platelet count (PLTo). For specimens aged over 24, the value of impedance platelet count yielded more reliable results than the routine PLTo. White blood cell (WBC) differential parameters, except eosinophils, were stable for up to 48 h at +23 +/- 2 degrees C. CBC parameters were stable for 72 h, except mean platelet volume, which slightly increased between 48 and 72 h, at +4 degrees C. WBC differentials were stable 48-72 h, with a slight decrease observed in absolute neutrophils and lymphocytes at +4 degrees C.

    Counting morphologically normal cells in human red blood cells (RBCs) is extremely beneficial in the health care field. We propose a three-dimensional (3-D) classification method of automatically determining the morphologically normal RBCs in the phase image of multiple human RBCs that are obtained by off-axis digital holographic microscopy (DHM). The RBC holograms are first recorded by DHM, and then the phase images of multiple RBCs are reconstructed by a computational numerical algorithm. To design the classifier, the three typical RBC shapes, which are stomatocyte, discocyte, and echinocyte, are used for training and testing. Nonmain or abnormal RBC shapes different from the three normal shapes are defined as the fourth category. Ten features, including projected surface area, average phase value, mean corpuscular hemoglobin, perimeter, mean corpuscular hemoglobin surface density, circularity, mean phase of center part, sphericity coefficient, elongation, and pallor, are extracted from each RBC after segmenting the reconstructed phase images by using a watershed transform algorithm. Moreover, four additional properties, such as projected surface area, perimeter, average phase value, and elongation, are measured from the inner part of each cell, which can give significant information beyond the previous 10 features for the separation of the RBC groups; these are verified in the experiment by the statistical method of Hotelling's T-square test. We also apply the principal component analysis algorithm to reduce the dimension number of variables and establish the Gaussian mixture densities using the projected data with the first eight principal components. Consequently, the Gaussian mixtures are used to design the discriminant functions based on Bayesian decision theory. To improve the performance of the Bayes classifier and the accuracy of estimation of its error rate, the leaving-one-out technique is applied. Experimental results show that the proposed method can

    This paper is the first report whether or not pneumatic tube system affects the selection of apheresis donors according to the results of complete blood count. According to the apheresis guidelines, hemoglobin level must be ≥12.5g/dL and platelet level ≥150/μL to be a donor. Paired blood samples of 26 healthy volunteers were transported by either hand delivered or a pneumatic tube system to the laboratory. No statistically significant differences were observed in order to mean values of routine complete blood cell count and white cell differential parameters that were send for selection of apheresis donor before the procedure. Therefore, all healthy volunteers decided as a donor according to the laboratory results independent from transport method.

    Full Text Available Abstract Background Smoking has been linked to low-grade systemic inflammation, a known risk factor for disease. This state is reflected in elevated white blood cell (WBC count. Objective We analyzed the relationship between WBC count and smoking in healthy men and women across several age ranges who underwent preventive medical check-ups in the workplace. We also analysed the relationship between smoking and lung function. Methods Cross-sectional descriptive study in 163 459 men and 59 382 women aged between 16 and 70 years. Data analysed were smoking status, WBC count, and spirometry readings. Results Total WBC showed higher counts in both male and female smokers, around 1000 to 1300 cell/ml (t test, P 1% was higher in nonsmokers for both sexes between 25 to 54 years (t test, P 1% were found to have higher WBC counts, in comparison to smokers with a normal FEV1% among similar age and BMI groups. Conclusions Smoking increases WBC count and affects lung function. The effects are evident across a wide age range, underlining the importance of initiating preventive measures as soon as an individual begins to smoke.

Preoperative peripheral blood monocyte counts, the T and N classifications of the primary tumour and its primary site differed significantly between the two groups (P rectal versus colon cancer (OR: 0.078, 95%CI: 0.020~0.309, P TNM staging and preoperative monocyte counts (P 0.505 × 109 cells/L, high T classification and liver metastasis were independent risk factors for 5-year OS (RR: 2.737, 95% CI: 1.573~ 4.764, P <0.001; RR: 2.687, 95%CI: 1.498~4.820, P = 0.001; RR: 4.928, 95%CI: 2.871~8.457, P < 0.001). The demonstrated association between preoperative peripheral blood monocyte count and liver metastasis in patients with CRC recommends the former as a useful predictor of postoperative prognosis in CRC patients.

    The purpose of this study was to assess the effects of exercise on the aerobic power, serum lactate level, and cell blood count among active individuals in the environments with similar climatic characteristics differing in their level of air pollution. This trial comprised 20 volunteer students of Physical education in The University of Isfahan, Iran. Two places with the same climate (altitude, temperature, and humidity), but low and high level of air pollutants air were selected in Isfahan, Iran. Participants underwent a field Cooper test with a 12-minute run for fitness assessment. Then the aerobic power, serum lactate, and cell blood counts were measured and compared between the two areas. The study participants had a mean (SD) age of 21.70 (2.10) years and body mass index (BMI) of 24.44 (2.32) Kg/m2. We found a significant decrease in mean Vo2 max, red blood cell count, hemoglobin, hematocrit, and mean corpuscular hemoglobin, as well as significant increase in mean lactate level, white blood cell count and mean corpuscular volume in the higher-polluted than in the lower-polluted area. No significant difference was documented for other parameters as platelet counts or maximum heart rate. Exercise in high-polluted air resulted in a significant reduction in the performance at submaximal levels of physical exertion. Therefore, the acute exposure to polluted air may cause a significant reduction in the performance of active individuals. The clinical importance of these findings should be assessed in longitudinal studies.

    Resveratrol is a phytoestrogen that has many beneficial actions. This study aimed to evaluate the effect of resveratrol on the complete blood count (CBC) and the acetylcholinesterase (AChE) activity of lymphocytes of ovariectomized rats experimentally demyelinated by ethidium bromide (EB). Forty adult female Wistar rats (60 days, 200-220 g) were divided randomly into five groups (n = 4) to evaluate the demyelination phase and five groups (n = 4) to evaluate the remyelination phase. In each phase, the groups consisted of sham rats-G1; ovariectomized rats, not demyelinated, treated only with vehicle (ethanol 25%)-G2; demyelinated ovariectomized rats treated only with vehicle-G3; ovariectomized rats, not demyelinated, treated with resveratrol-G4; and demyelinated ovariectomized rats treated with resveratrol-G5. Only during the remyelination phase, CBC showed a significant difference (p < 0.05) in the number of monocytes between G2 and G5 groups. In the demyelination phase, there was a significant decrease (p < 0.05) in the AChE activity in the G4 group, while the G5 group was statistically similar to the G1, G2 and G4 groups. In the remyelination phase, there were no significant differences in the AChE activity among the groups. The treatment for 7 days with resveratrol with or without the experimental demyelization with EB appears to influence the AChE activity of lymphocytes, without changing the number of these cells in the circulation. However, in the remyelination phase, there seems to be stabilization in its effect on the lymphocyte AChE activity.

    Full Text Available Cold agglutinin disease is an autoimmune disorder that is characterized by antibodies attacking polysaccharide antigens on one’s own erythrocytes. In cold agglutinin disease, hemolysis occurs due to degeneration of erythrocyte membranes and autoagglutination of erythrocytes. Both autoagglutination and hemolysis alter many laboratory test results of the patients, especially complete blood count (CBC and peripheral blood smear analyses. In our laboratory, we have encountered a blood sample of a 65-years-old man, who was independently diagnosed with cold agglutinin disease, and failed to produce meaningful CBC or peripheral blood smear analysis. Fresh blood samples were taken from the patient, and CBC and peripheral blood smear analyses were repeated with and without water bath incubation at 37 °C. Also, varying amounts of dithio­threitol (DTT were added to fresh samples without heat treatment prior to blood analysis. Heat treatment at 37 °C for varying lengths of time failed to improve CBC and peripheral blood smear analysis. On the other hand, addition of DTT into a blood sample of 2 ml in a K3-EDTA tube was sufficient to negate cold agglutination interference during both CBC and peripheral blood smear analyses. The presented method supports the potential for DTT to be used in negating cold agglutination interference during CBC and peripheral blood smear analyses of patients with cold agglutinin disease. The method we describe is very easy and quick with remarkable results.

    The Metabolic Syndrome (MetS) is a cluster of metabolic abnormalities that includes hyperglucemia, hypertension, dyslipidemia and central obesity, conferring an increased risk of cardiovascular disease. The white blood cell (WBC) count has been proposed as a marker for predicting cardiovascular risk. However, few prospective studies have evaluated the relationship between WBC subtypes and risk of MetS. Participants were recruited from seven PREDIMED study centers. Both a baseline cross-sectional (n = 4,377) and a prospective assessment (n = 1,637) were performed. Participants with MetS at baseline were excluded from the longitudinal analysis. The median follow-up was 3.9 years. Anthropometric measurements, blood pressure, fasting glucose, lipid profile and WBC counts were assessed at baseline and yearly during the follow-up. Participants were categorized by baseline WBC and its subtype count quartiles. Adjusted logistic regression models were fitted to assess the risk of MetS and its components. Of the 4,377 participants, 62.6% had MetS at baseline. Compared to the participants in the lowest baseline sex-adjusted quartile of WBC counts, those in the upper quartile showed an increased risk of having MetS (OR, 2.47; 95%CI, 2.03-2.99; P-trendcomponents hypertriglyceridemia and low HDL-cholesterol. Likewise, lymphocyte counts were found to be associated with the incidence of the MetS components low HDL-cholesterol and high fasting glucose. An increase in the total WBC during the follow-up was also associated with an increased risk of MetS. Total WBC counts, and some subtypes, were positively associated with MetS as well as hypertriglyceridemia, low HDL-cholesterol and high fasting glucose, all components of MetS.

    The most important factor for the selection of an umbilical cord blood unit (CBU) for hematopoietic stem cell transplantation is the total nucleated cell (TNC) count as a surrogate marker for stem cell content in the CBU. At present, about one in five donors can provide a CBU with a sufficient TNC count for umbilical cord blood (UCB) banking. It is labor-intensive to obtain consent of all eligible donors and optimization of the selection is needed. The purpose of this study was to investigate prenatal clinical predictors for TNC count that would help to identify successful UCB donors already on admission to the delivery unit. This study was a retrospective analysis of 758 cryopreserved CBUs, collected from 2002 to 2006. Maternal and fetal factors analyzed were maternal age, gravidity, parity, weight, height, diabetes, premature rupture of membranes, gestational age, fetal sex, and birthweight. The impact on a high TNC count (banking rates from 22.7% to 31.9% while decreasing the number of banked CBUs from 149 to 79. Our prenatal prediction model increases the efficacy of obtaining informed consent for UCB banking while still allowing relevant numbers of CBUs to be banked. © 2014 AABB.

    Abnormal complete blood count (CBC) and high plasma C-reactive protein (CRP) are associated with neonatal infections and could be helpful in the diagnosis of neonatal sepsis and to monitor the antibiotic treatment. The aim of this work is to evaluate and compare the performance of a bedside analyzer for blood count and C-reactive protein (CRP) with a conventional analyzer in a neonatal population. 150 capillary or venous blood samples of term and preterm newborns were processed on an ABX-MicrosCRP200 analyzer and on a SysmexXE2100 (conventional hematology analyzer) for CBC, leukocyte differential, reticulocytes, and nucleated red blood cells (NRBC); high-sensitivity CRP (hs-CRP) was performed on a ModularPE. The differences between complete blood count and CRP were regressed against their means and assessed by means of intra-class-correlation. The intra-class-correlation for white blood cell (WBC) was 0.98, for hemoglobin 0.97, for hematocrit 0.96, for mean corpuscular volume 0.95, and for platelet 0.98. ABX-MicrosCRP200 overestimated the WBC (+1.27 x 10(3)/microL; p < 0.001), hematocrit (+1.80%; p < 0.001), and platelet (+13.55 x 10(3)/microL; p < 0.001). The intra-class-correlation for CRP was high (0.97), without systematic difference between the two values (p = 0.64). The agreement between the two methods was high for both tests. However, the SD of the difference for WBC and platelet could be clinically important in leukopenic or thrombocytopenic newborns.

    A significant association between elevated white blood cell (WBC) count and mortality in patients with cancer has been reported, but the predictive value of elevated WBC on mortality in cancer patients with acute venous thromboembolism (VTE) has not been explored. RIETE is an ongoing registry of consecutive patients with acute VTE. We compared the three-month outcome of cancer patients with acute VTE according to their WBC count at baseline. As of May 2007, 3805 patients with active cancer and acute VTE had been enrolled in RIETE. Of them, 215 (5.7%) had low- (11,000 cells/microl) WBC count. During the study period 190 patients (5.0%) had recurrent VTE, 156 (4.1%) major bleeding, 889 (23%) died (399 of disseminated cancer, 113 of PE, 46 of bleeding. Patients with elevated WBC count at baseline had an increased incidence of recurrent VTE (odds ratio [OR]: 1.6; 95% confidence interval [CI]: 1.2-2.2), major bleeding (OR: 1.5; 95% CI: 1.1-2.1) or death (OR: 2.7; 95% CI: 2.3-3.2). Most of the reported causes of death were significantly more frequent in patients with elevated WBC count. Multivariate analysis confirmed that elevated WBC count was independently associated with an increased incidence of all three complications. In conclusion, cancer patients with acute VTE and elevated WBC count had an increased incidence of VTE recurrences, major bleeding or death. This worse outcome was consistent among all subgroups and persisted after multivariate adjustment.

    The role of white blood cell (WBC) count in pathogenesis of diabetes, cardiovascular disease, and obesity-related disorders has been reported earlier. Recent studies revealed that higher WBC contributes to atherosclerotic progression and impaired fasting glucose. However, it is unknown whether variations in WBC and haematologic profiles can occur in healthy obese individuals. The aim of this study is to further evaluate the influence of obesity on WBC count, inflammatory biomarkers, and metabolic risk factors in healthy women to establish a relationship among variables analyzed. The sample of the present study consisted of 84 healthy women with mean age of 35.56 +/- 6.83 years. They were categorized into two groups based on their body mass index (BMI): obese group with BMI > 30 kg/m2 and non-obese group with BMI count (PLT) with serum interleukin 6 (IL-6), C-reactive protein (CRP), angiotensin pi (Ang pi), body fat percentage (BF %), waist-circumference (WC), and lipid profile. WBC, PLT, CRP, and IL-6 in obese subjects were significantly higher than in non-obese subjects (p count in obese subjects was 6.4 +/- 0.3 (x10(9)/L) compared to 4.4 +/- 0.3 (x10(9)/L) in non-obese subjects (p = 0.035). WBC correlated with BF% (r = 0.31, p = 0.004), CRP (r = 0.25, P = 0.03), WC (r = 0.22, p = 0.04), angiotensin 11 (r = 0.24, p = 0.03), triglyceride (r = 0.24, p = 0.03), and atherogenic index of plasma (AIP) levels (r = 0.3, p = 0.028) but not with IL-6. Platelet count was also associated with WC and waist-to-hip ratio (p count and inflammatory parameters. There was also a positive relationship between WBC count and several inflammatory and metabolic risk factors in healthy women.

    Full Text Available Aim: The present study was aimed to study the use of cell counts as an early indicator of mammary health. Materials and Methods: Milk and blood cell counts were estimated from 8 healthy, 8 subclinical (SCM, and 8 clinically mastitis (CM groups of Karan Fries (KF cows. Results: Total leucocyte counts and neutrophil percent in blood and milk somatic cells and milk neutrophil percent of healthy cows increased significantly (p<0.05 in SCM cows and CM cows. Viability of blood and milk neutrophils was more in healthy cows, but decreased significantly (p<0.05 in SCM and CM cows. Significant (p<0.05 decrease were also observed in both the blood and milk lymphocytes and monocytes of SCM and CM cows. Phagocytic activity (PA of blood neutrophils also decreased significantly (p<0.05 in SCM cows. There was no difference between the PA of SCM and CM cows. Milk neutrophil percent was more in the SCM and clinically infected milk than in the blood of these cows. About 96-97% of the neutrophils had segmented nucleus in both healthy and subclinical milk, whereas, 2-3% were having band shaped or immature nuclei. There was a significant decrease in the segmented neutrophils, whereas, band neutrophils increase significantly to about 5% in the infected milk of mastitic cows. Viability of the milk neutrophils decreased more in case of subclinical and clinical milk as compared to that of blood. PA was found to be highest in the milk of healthy group of cows, but decreased significantly (p<0.05 in subclinically infected cows. However, there was no difference between the PA of milk neutrophils of SCM and CM cows. PA of milk was also found to be significantly lower in the milk of healthy cows when compared to that of blood neutrophils. Conclusion: This study indicated that percent neutrophils and their type in conjunction with milk somatic cell counts can be used as a more reliable indicator of mammary health in cows.

    Since the advent of automation in the field of hematological cell counters there has been a constant refinement of the technology and increase in the number of newer parameters available on CBC analysers. Many novel parameters are being put into routine clinical use and both clinical evaluation and monitoring critically depend on knowledge of laboratory reference ranges. Here, we present reference interval for the Sysmex XE-2100, with emphasis on the novel or newer research parameters. Blood samples from a total of 122 clinically asymptomatic and apparently healthy subjects were evaluated and a final of 100 subjects (54-M, 46-F) were included in the study. A broad spectrum of parameters available with the analyser was assessed and reference ranges for the same evaluated.

    Background The Metabolic Syndrome (MetS) is a cluster of metabolic abnormalities that includes hyperglucemia, hypertension, dyslipidemia and central obesity, conferring an increased risk of cardiovascular disease. The white blood cell (WBC) count has been proposed as a marker for predicting cardiovascular risk. However, few prospective studies have evaluated the relationship between WBC subtypes and risk of MetS. Methods Participants were recruited from seven PREDIMED study centers. Both a baseline cross-sectional (n = 4,377) and a prospective assessment (n = 1,637) were performed. Participants with MetS at baseline were excluded from the longitudinal analysis. The median follow-up was 3.9 years. Anthropometric measurements, blood pressure, fasting glucose, lipid profile and WBC counts were assessed at baseline and yearly during the follow-up. Participants were categorized by baseline WBC and its subtype count quartiles. Adjusted logistic regression models were fitted to assess the risk of MetS and its components. Results Of the 4,377 participants, 62.6% had MetS at baseline. Compared to the participants in the lowest baseline sex-adjusted quartile of WBC counts, those in the upper quartile showed an increased risk of having MetS (OR, 2.47; 95%CI, 2.03–2.99; P-trend<0.001). This association was also observed for all WBC subtypes, except for basophils. Compared to participants in the lowest quartile, those in the top quartile of leukocyte, neutrophil and lymphocyte count had an increased risk of MetS incidence. Leukocyte and neutrophil count were found to be strongly associated with the MetS components hypertriglyceridemia and low HDL-cholesterol. Likewise, lymphocyte counts were found to be associated with the incidence of the MetS components low HDL-cholesterol and high fasting glucose. An increase in the total WBC during the follow-up was also associated with an increased risk of MetS. Conclusions Total WBC counts, and some subtypes, were positively

    Early detection of iron deficiency (ID) and iron deficiency anemia (IDA) in young children is important to prevent impaired neurodevelopment. Unfortunately, many biomarkers of ID are influenced by infection, thus limiting their usefulness. The aim of this study was to investigate the value of red blood cell distribution width (RDW) and the platelet count for detecting ID(A) among otherwise healthy children. A multicenter prospective observational study was conducted in the Netherlands to investigate the prevalence of ID(A) in 400 healthy children aged 0.5-3 years. ID was defined as serum ferritin (SF) count were determined in the complete blood cell count. RDW was inversely correlated with SF and not associated with CRP. Calculated cutoff values for RDW to detect ID and IDA gave a relatively low sensitivity (53.1% and 57.1%, respectively) and specificity (64.7% and 69.9%, respectively). Anemic children with a RDW >14.3% had a 2.7 higher odds (95% confidence interval [CI]: 1.2-6.3) to be iron deficient, compared with anemic children with a RDW count showed a large range in both ID and non-ID children. In conclusion, RDW can be helpful for identifying ID as the cause of anemia in 0.5- to 3-year-old children, but not as primary biomarker of ID(A). RDW values are not influenced by the presence of infection. There appears to be no role for the platelet count in diagnosing ID(A) in this group of children.

    Purpose: Radiation pneumonitis (RP) is an inflammatory response to radiation therapy (RT). We assessed the association between RP and white blood cell (WBC) count, an established metric of systemic inflammation, after RT for non-small cell lung cancer. Methods and Materials: We retrospectively analyzed 366 patients with non-small cell lung cancer who received ≥60 Gy as definitive therapy. The primary endpoint was whether WBC count after RT (defined as 2 weeks through 3 months after RT completion) was associated with grade ≥3 or grade ≥2 RP. Median lung volume receiving ≥20 Gy (V{sub 20}) was 31%, and post-RT WBC counts ranged from 1.7 to 21.2 × 10{sup 3} WBCs/μL. Odds ratios (ORs) associating clinical variables and post-RT WBC counts with RP were calculated via logistic regression. A recursive-partitioning algorithm was used to define optimal post-RT WBC count cut points. Results: Post-RT WBC counts were significantly higher in patients with grade ≥3 RP than without (P<.05). Optimal cut points for post-RT WBC count were found to be 7.4 and 8.0 × 10{sup 3}/μL for grade ≥3 and ≥2 RP, respectively. Univariate analysis revealed significant associations between post-RT WBC count and grade ≥3 (n=46, OR=2.6, 95% confidence interval [CI] 1.4‒4.9, P=.003) and grade ≥2 RP (n=164, OR=2.0, 95% CI 1.2‒3.4, P=.01). This association held in a stepwise multivariate regression. Of note, V{sub 20} was found to be significantly associated with grade ≥2 RP (OR=2.2, 95% CI 1.2‒3.4, P=.01) and trended toward significance for grade ≥3 RP (OR=1.9, 95% CI 1.0-3.5, P=.06). Conclusions: Post-RT WBC counts were significantly and independently associated with RP and have potential utility as a diagnostic or predictive marker for this toxicity.

    Full Text Available The systemic effect of low temperature suggests that sessions in a cryogenic chamber might improve athletes’ capacity as a standard element of training. Therefore the authors decided to evaluate the impact of 10 sessions of whole body cryostimulation (WBCT on aerobic and anaerobic efficiency as well as on selected blood count parameters. The study group included 32 volunteers – 16 women and 16 men. The volunteers underwent 10 sessions of WBCT in a cryogenic chamber. Blood samples (RBC, WBC, PLT, HGB, HCT were taken, and aerobic and anaerobic efficiency and lactate concentration in capillary blood were measured before the first session and one day after the last one. No significant differences were observed in values of aerobic capacity after 10 sessions of WBCT. There was a rising trend in men and a declining trend in women. The lactate concentration did not differ significantly before and after WBCT. A slight rise in aerobic and anaerobic threshold was observed in men, while in women the values slightly fell. The Wingate test showed no significant differences in results before and after cryostimulation. Only the TOBT was significantly shorter in men (6.12±1.49 vs 3.79±1.14 s. The WBCT sessions resulted in a significant rise of the haematological parameters both in women and men, excluding HCT, which showed a statistically insignificant rise. Ten sessions of whole body cryostimulation did not affect aerobic or anaerobic capacity in the tested group, although it improved the blood count parameters.

    Bronchial carcinoids are uncommon pulmonary neoplasms and represent 1 to 2 % of all lung tumors. In early stage of disease, the mainstay and only curative treatment is surgery. Bronchial carcinoids are generally regarded as low-grade carcinomas and metastatic dissemination is unusual. The management of the metastatic stage is not currently standardized due to a lack of relevant studies. As bronchial carcinoids and in particular their metastatic forms are rare, we apply treatment strategies that have been evaluated in gastrointestinal and pancreatic neuroendocrine tumors. However, bronchial carcinoids have their own characteristic. A specific therapeutic feature of these metastatic tumors is that they require a dual approach: both anti-secretory for the carcinoid syndrome, and anti-tumoral.

    Aurora Flight Sciences, in partnership with Draper Laboratory, has developed a miniaturized system to count white blood cells in microgravity environments. The system uses MEMS technology to simultaneously count total white blood cells, the five white blood cell differential subgroups, and various lymphocyte subtypes. The OILWBCS-MEMS detection technology works by immobilizing an array of white blood cell-specific antibodies on small, gold-coated membranes. When blood flows across the membranes, specific cells' surface protein antigens bind to their corresponding antibodies. This binding can be measured and correlated to cell counts. In Phase I, the partners demonstrated surface chemistry sensitivity and specificity for total white blood cells and two lymphocyte subtypes. In Phase II, a functional prototype demonstrated end-to-end operation. This rugged, miniaturized device requires minimal blood sample preparation and will be useful for both space flight and terrestrial applications.

    Tests were conducted to prove that muscular exertion (in this instance swimming) of different duration and intensity, as well as hypodynamia, result in an increase of hemoglobin and number of red blood cells in peripheral blood rats. Catalase activity increased with an increase in the duration of swimming, but only up to 6 hr; with 7-9 hr of swimming as well as in hypodynamia, catalase activity decreased. It was also observed that under hypodynamia as well as in 3, 5 and 6 hr exertion (swimming) the color index of blood decreased. Pressure chamber treatment (for 8 min each day for one week), alternating a 2 min negative pressure up to 35 mm Hg with 1 min positive pressure, increased the erythrocyte count and hemoglobin content.

    Full Text Available Recent studies reported seasonal differences in gene expression in white blood cells, adipose tissue, and inflammatory biomarkers of the immune system. There is no data on the seasonal variations of these biomarkers in the US general population of both children and adults. Then aim of this study is to explore the seasonal trends in complete blood count (CBC, and C-reactive protein (CRP in a large non-institutionalized US population.Seven cross-sectional data collected in the National Health and Nutrition Examination Survey (NHANES during 1999-2012 were aggregated; participants reporting recent use of prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. Linear regression models were used to compare levels of CBC and CRP between winter-spring (November-April and summer-fall (May-October, adjusting for demographics, personal behavioral factors, and chronic disease conditions.A total of 27,478 children and 36,644 adults (≥18 years were included in the study. Levels of neutrophils, white blood cell count (WBC, and CRP were higher in winter-spring than summer-fall (p≤0.05. Red blood cell components were lower in winter-spring than in summer-fall, while the opposite was seen for platelets.This large population-based study found notable seasonal variations in blood cell composition and inflammatory biomarkers, with a more pro-inflammatory immune system seen in winter-spring than summer-fall. The red blood cell patterns could have implications for the observed cardio-vascular seasonality.

    Cell counting in human body fluids such as blood, urine, and CSF is a critical step in the diagnostic process for many diseases. Current automated methods for cell counting are based on flow cytometry systems. However, these automated methods are bulky, costly, require significant user expertise, and are not well suited to counting cells in fluids other than blood. Therefore, their use is limited to large central laboratories that process enough volume of blood to recoup the significant capital investment these instruments require. We present in this talk a combination of a (1) low-cost microscope system, (2) simple sample preparation method, and (3) fully automated analysis designed for providing cell counts in blood and body fluids. We show results on both humans and companion and farm animals, showing that accurate red cell, white cell, and platelet counts, as well as hemoglobin concentration, can be accurately obtained in blood, as well as a 3-part white cell differential in human samples. We can also accurately count red and white cells in body fluids with a limit of detection ~3 orders of magnitude smaller than current automated instruments. This method uses less than 1 microliter of blood, and less than 5 microliters of body fluids to make its measurements, making it highly compatible with finger-stick style collections, as well as appropriate for small animals such as laboratory mice where larger volume blood collections are dangerous to the animal's health.

    Veterinarians rely on results of both the complete blood cell count (CBC) and plasma protein electrophoresis (EPH) in conjunction with the results of the plasma biochemical analysis to evaluate the health status of avian patients. Because the CBC and protein EPH measure different aspects of the immune response to disease, both tests are recommended in avian patients to rule out infectious or inflammatory disease. To evaluate results of the CBC and protein EPH in pet psittacine birds, the records of 144 pet psittacine birds, comprising 11 genera, that were presented for suspected illness were reviewed. Results of the CBC (total white blood cell count and packed cell volume) and protein EPH (alpha, beta, and gamma globulin concentrations) from submitted blood samples from each bird were evaluated. Of the 144 birds, 63 (43.8%) had abnormal CBC results, and 25 (17.4%) had abnormal EPH measurements. Results of the CBC and protein EPH were within reference ranges in 73 birds (50.7%). Abnormal results of the CBC in conjunction with normal EPH results were present in 46 birds (31.9%), compared with 8 birds (5.6%) with normal results of the CBC and abnormal EPH results. The findings of this study could aid practitioners in evaluating psittacine patients and prioritizing the value of individual diagnostic tests.

    Full Text Available Considering the incidence of meconium-stained amniotic fluid (MSAF in newborns and its complications, and also based on indirect reports pointing out relationship between nucleated red blood cell (nRBC, as a marker of chronic hypoxia, and MSAF in term newborns, and in order to determine this relationship more accurately, this study was done on women with uncomplicated singleton term pregnancy that admitted for delivery at Shariati hospital in year 2000. After excluding confounding factors on nRBC, case group who includes infants with MSAF, and control group who have clear amniotic fluid were determined. Maternal age and parity, gestational age, birth weight, apgar score, neonatal out come, and FHR pattern as well as newborn hemoglobin values were evaluated. Venous cord blood was analyzed for nRBC counts per 100 WBC. Case and control groups were divided according to nRBC counts with cutoff point of 10 and then compared statistically. From the samples, 117 cases and 67 controls were evaluated. Maternal and neonatal factors were similar in two situations. Number of nRBC was 3.75±4.8 in control group and 12.04±11.7 in case group (P<0.01 and it was abnormal (>10 in 9 percent of newborns with clear fluid and 32 percent of MSAF (P<0.01. Cord blood nRBC count increased when meconium is passed intrauterine. This suggests that cases with MSAF may be at risk of chronic hypoxia. Cohort research is recommended to study the affect of delivery mode on the neonatal outcome in cases with MSAF and to evaluate the cause of fetal hypoxia in uncomplicated pregnancy with MSAF.

Thirty-six patients with localized testicular cancer with a mean age of 34.22±14.89 years and 36 healthy controls with a mean age of 26.67±2.89 years were enrolled in the study. White blood cell counts and NLR were calculated from complete blood cell counts. White blood cell counts and NLR were statistically significantly higher in patients with testicular cancer compared with the control group (ptesticular cancer besides the well-known accurate serum tumor markers as AFP (alpha fetoprotein), hCG (human chorionic gonadotropin) and LDH (lactate dehydrogenase).

    Preliminary evaluation of quantitative clinical laboratory measurements is a prerequisite for the accreditation of clinical laboratories, according to the French Committee of Accreditation guidelines following the European reference Standard EN ISO 15189. Numerous papers have been published regarding biochemistry and immunology. However, data are lacking for automated complete blood count accreditation. We report here our experience at Hôpital européen Georges Pompidou hematology laboratory and present the performance characteristics of two mirrored LH750 Beckman-Coulter analysers, including precision, accuracy and uncertainty of measurement.

    Full Text Available Abstract Background Cigarette smokers have increased white blood cell (WBC counts and the activation of tumor necrosis factor (TNF. The effect of smoking on WBC counts and TNF system activity, however, has not been separately investigated yet. Subjects and Methods One hundred and forty-two Japanese male subjects with normal glucose tolerance were recruited. They were stratified into two groups based on the questionnaire for smoking: one with current smokers (n = 48 and the other with current non-smokers (n = 94. Whereas no significant differences were observed in age, BMI, high molecular weight (HMW adiponectin, and TNF-α between the two groups, current smokers had significantly higher soluble TNF receptor 1 (sTNF-R1 (1203 ± 30 vs. 1116 ± 21 pg/ml, p = 0.010 and increased WBC counts (7165 ± 242 vs. 5590 ± 163/μl, p p = 0.031 as compared to current non-smokers. Next, we classified 48 current smokers into two subpopulations: one with heavy smoking (Brinkman index ≥ 600 and the other with light smoking (Brinkman index Results Whereas no significant difference was observed in age, BMI, HMW adiponectin, WBC counts and TNF-α, sTNF-R1 and sTNF-R2 were significantly higher in heavy smoking group (1307 ± 44 vs. 1099 ± 30 pg/ml, p p = 0.005 than in light smoking group, whose sTNF-R1 and sTNF-R2 were similar to non-smokers (sTNF-R1: 1116 ± 15 pg/ml, p = 0.718, sTNF-R2; 1901 ± 32 pg/ml, p = 0.437. In contrast, WBC counts were significantly increased in heavy (7500 ± 324/μl, p p = 0.001 smoking group as compared to non-smokers (5590 ± 178/μl. There was no significant difference in WBC counts between heavy and light smoking group (p = 0.158. Conclusion We can hypothesize that light smoking is associated with an increase in WBC counts, while heavy smoking is responsible for TNF activation in Japanese male subjects with normal glucose tolerance.

    Body mass index (BMI), the prevalent indicator of obesity, is not easily grasped by patients nor physicians. Waist circumference (WC) is correlated to obesity, is better understood and has a stronger relationship to the metabolic syndrome. We compiled WC, complete blood count (CBC) parameters as well as other pertinent data of 6766 25-55-year-old US volunteers sampled in the US National Health and Nutrition Examination Survey, in the years 2005-2010. To determine reference intervals of typical US patients visiting their clinician, we used minimal exclusion criteria. We compiled hemoglobin, red blood cell count, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration, mean cell hemoglobin (MCH), red cell distribution width (RDW), platelet count, mean platelet volume, and counts of white blood cells (WBC), neutrophils, lymphocytes, monocytes, eosinophils, and basophils. In addition, we also compiled serum C reactive protein and serum iron. The three major US races were studied and reference interval diagrams were constructed for each CBC parameter plotted against WC. WBC count, RDW, lymphocyte, neutrophil, and red blood cell count increase with WC. Conversely, serum iron and MCH and MCV decrease. These relationships may be related to insulin resistance and chronic activation of the immune system and the resulting low-grade inflammatory state. WC is a strong predictor for many CBC parameters, suggesting that WC should be taken into account when evaluating blood count results. Clinicians who take care of obese patients should be aware of altered hematology and investigate and treat accordingly.

    Full Text Available The leading pathophysiological changes during sepsis include systemic abnormalities in the immune
    response. Due to the general character of these disturbances, sepsis is usually studied as a homogenous clinical
    condition. We aimed to compare the immune response in intraabdominal sepsis (IAS and pneumonia-derived
    sepsis (PDS. The following cell populations were examined: white blood cell count (WBC, monocytes, lymphocytes:
    CD3+, CD4+ and CD8+ T cells, B cells, and NK cells. In both studied groups (i.e. IAS and PDS, the
    WBC was elevated. However, it was significantly higher in the IAS group than in the PDS group. The difference
    was due to a lower granulocyte count, as well as a lower monocyte count in PDS. We found no significant
    correlation between the total lymphocyte number and CD3+CD8+ T cells in either form of sepsis. Similarly, we
    observed no correlation between the total lymphocyte number and the NK cells subset in IAS. However, the
    numbers of CD3+CD8+ and NK cells correlated similarly in both types of sepsis. Both studied types of sepsis
    induced profound lymphocytopenia, with marked loss of CD8+ T cells and the NK cells. However, the similar
    relation between them, which was independent of the infection type, suggests that the NK and CD3+CD8+ cells
    have shared mechanisms of regulation. The primary site of infection has an impact on the global immune reaction.
    These alternations include especially myeloid cells: granulocytes and monocytes which disappear from peripheral
    blood during PDS, but increase in IAS.

    Objective: To observe changes in RBC count, changes, RBC morphology, and serum potassium during compressed transfusion of WBC-removal whole blood. Methods: Prepared human WBC-removal whole blood and connected transfusion apparatus with different sizes of intravenous detaining needles ( 18G, 20G, 22G and 24G) . Observed RBC count and serum potassium concentration under different pressures ( 100 mmHg, 200 mmHg, and 300 mmHg) as blood flowed out of the pinhead end of the intravenous detaining needle. Samples ob-tained with the 20G needle were smeared on glass slides, and RBC morphologic changes were ob-served under an oil immersion lens. Results: RBC count and serum potassium changed slightly under different pressures with differ-ent sizes of intravenous detaining needles as blood flowed through the transfusion apparatus. In ad-dition, the observation of blood samples under a common light microscope revealed that coarse-prick, oblong, and spindle cell counts in the visual fields increased gradually as the pressure in-creased. Additionally, a portion of cells had undergone splintering. Conclusions: While applying 18G, 20G, 22G and 24G intravenous detaining needles for blood transfusion under less than 300 mmHg of pressure, no significant RBC count change was found in blood samples in the short term. However, there were significant RBC morphologic changes. The results could offer more basis to ensure the clinical safety of patients undergoing blood transfusion.

    Full Text Available The rapid growth in microelectronics and crunching RISC in the field of bio-medical sciences incorporated of soft tools to diagnose various parameters of human fluids. Conventional method of blood sample analysis makes use of laboratory technique of titration, which is operator-dependent and results in lot of errors depending on the skill of the technician. In order to eliminate the human errors involved in the conventional method, in this paper an attempt has been made to present a capillary centrifuge technique driven by high speed DC motor fed by Morgan chopper and controlled by powerful ARM processor. It results in accurate analysis of the blood samples. The various techniques involved in accurate sensing of speed using timer and generation of firing pulses to thyristor in the Morgan chopper is judiciously achieved. This paper clearly brings out the advantages of the proposed blood measurement technique which effectively gives blood analysis faster and at a low cost.

    INTRODUCTION: Acute appendicitis (AA) remains a diagnostic challenge as indicated by the high rate of unnecessary surgery. Blood samples, primarily C-reactive protein (CRP) and leucocyte counts, are used as a diagnostic supplement despite their relatively low sensitivities and specificities....... However, their influence on diagnostic decision-making has not previously been investigated. The aim of the present study was to investigate if the results of CRP and leucocytes had any positive or negative influence on the decision-making of surgeons handling patients with suspected AA. METHODS...... the blood results and re-evaluate their diagnosis. The surgeon's diagnosis before and after was compared with the final diagnosis defined by surgical findings or follow-up. The gold standard was any degree of appendicitis on histology. RESULTS: A total of 226 patients were included of whom 91 (40.3%) had...

    Severe scoliosis may have a significant effect on respiratory function. The effect is most often restrictive due to severe anatomical distortion of the chest, leading to reduced lung volumes, limited diaphragmatic excursion and chest wall muscle inefficiency. Bronchial compression by the deformed spine may also occur but is more unusual. Management options include a conservative approach using bracing and physiotherapy in mild cases, as well as surgical correction of the scoliosis in more severe cases. Bronchial stenting has also been used successfully as an alternative to surgical correction, and in cases in which spinal surgery was either unsuccessful or not feasible. The authors present a case involving a 52-year-old woman who exhibited symptomatic compression of the bronchus intermedius by severe residual scoliosis despite previous corrective surgery. She was treated with an indwelling bronchial stent.

    Expression of CD56 has recently been introduced as one of the adverse prognostic factors in acute promyelocytic leukemia (APL). However, the clinical significance of CD56 antigen in APL has not been well elucidated. We assessed the clinical significance of CD56 antigen in 239 APL patients prospectively treated with all-trans retinoic acid and chemotherapy according to the Japan Adult Leukemia Study Group APL97 protocol. All patients were prospectively treated by the Japan Adult Leukemia Study Group APL97 protocol. The median follow-up period was 8.5 years. Positive CD56 expression was found in 23 APL patients (9.6%). Expression of CD56 was significantly associated with lower platelet count (P = 0.04), severe disseminated intravascular coagulation (P = 0.04), and coexpression of CD2 (P = 0.03), CD7 (P = 0.04), CD34 (P < 0.01) and/or human leukocyte antigen-DR (P < 0.01). Complete remission rate and overall survival were not different between the two groups. However, cumulative incidence of relapse and event-free survival (EFS) showed an inferior trend in CD56(+) APL (P = 0.08 and P = 0.08, respectively). Among patients with initial white blood cell counts of 3.0 × 10(9)/L or more, EFS and cumulative incidence of relapse in CD56(+) APL were significantly worse (30.8% vs 63.6%, P = 0.008, and 53.8% vs 28.9%, P = 0.03, respectively), and in multivariate analysis, CD56 expression was an unfavorable prognostic factor for EFS (P = 0.04). In conclusion, for APL with higher initial white blood cell counts, CD56 expression should be regarded as an unfavorable prognostic factor.

    Abstract Radioactive iodine (RAI) is considered to be related with hematologic changes. This study aimed to evaluate influence of the first RAI ablation on peripheral complete blood count (CBC) in patients with differentiated thyroid cancer (DTC). Data of CBC at baseline and 6 months after RAI were obtained in 385 patients with DTC with approximately 3700 MBq 131I (ranging 2220–7585 MBq). Further comparison was done in 196 patients with 1-month postablation data available. Routine blood examinations were performed to determine impact of RAI on white blood cell (WBC), red blood cell (RBC), hemoglobin, platelet, neutrophil, lymphocyte, and monocyte in both sexes. Continuous variables were compared by paired t tests and independent samples t test, and categorical variables were compared by chi-square analysis. Data with repeated measurements were analyzed by analysis of variance. The first RAI after thyroidectomy was associated with mild, yet significant declines in WBC, platelet, and lymphocyte, which persisted for 6 months. One month after RAI, significant declines were found in all CBC, including RBC and hemoglobin (all P DTC. PMID:27583853

    We have gravimetrically calibrated the volumes dispensed by 1 mL syringes in the range between 1 µL and 100 µL using ultra-pure water. Protocols are based on series of consecutive difference measurements of masses in order to precisely compensate for evaporation, being the most important disturbing quantity. We determined expanded uncertainties of volume measurements for glass syringes of typically 0.2% (expansion factor 2) when dispensing volumes of 10 µL. For polypropylene syringes, selected with respect to the manufacturer, expanded uncertainties of 0.25% (expansion factor 2) were observed. Calibrated syringes were applied for measuring concentrations of blood cells in a flow cytometer demonstrating the capability to determine reference measurement values. Since the direct interaction of blood cells and syringe walls may lead to cell adhesion, glass syringes as well as (disposable) polypropylene syringes were calibrated.

    To determine reference values for full blood count parameters in a population of children 8 to 12 years old, living at an altitude of 2760 m above sea level. Our sample consisted of 102 individuals on whom a full blood count was performed. The parameters included: total number of red blood cells, platelets, white cells, and a differential count (millions/μl and %) of neutrophils, lymphocytes, monocytes, eosinophils and basophils. Additionally, we obtained values for hemoglobin, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, concentration of corpuscular hemoglobin and red blood cell distribution width. The results were statistically analyzed with a non-parametric test, to divide the sample in quartiles and obtain the lower and upper limits for our intervals. Moreover, the values for the intervals obtained from this analysis were compared to intervals obtained estimating+- 2 standard deviations above and below from our mean values. Our results showed significant differences compared to normal interval values reported for the adult Mexican population in most of the parameters studied. The full blood count is an important laboratory test used routinely for the initial assessment of a patient. Values of full blood counts in healthy individuals vary according to gender, age and geographic location; therefore, each population should have its own reference values.

    The peripheral blood mononuclear cell (PBMC) count is a routinely used and meaningful index for infection and blood diseases. PBMCs may be closely related to osteoclasts and include osteoclast precursors; we examined the association between the PBMC count and bone health. This research included 2806 community men aged ≥50 years who underwent full health examinations from October 2007 through December 2011 in four medical centers. The PBMC count was significantly high among subjects with "at least osteopenia" compared with controls. In analysis of covariance adjusted for potential confounders, the bone mineral density (BMD) value and T-score had a significant decreasing trend across the quartiles of PBMC count. In univariate analysis, the PBMC count had a strong association with "at least osteopenia" (odds ratio [OR] = 2.520, 95% confidence interval [CI]: 1.397-4.547). After adjustment for confounding factors (multivariate analysis) from Model 1 to 4, PBMC count remained as an independent risk factor for "at least osteopenia" (OR = 2.481, 95% CI: 1.176-5.236). Moreover, after adjusting for all confounding variables, participants had a significantly high OR in the body mass index (BMI) blood pressure (SBP) count is significantly associated with bone loss in elderly men and the exact mechanism requires further clarification.

Methods Febrile children presenting to the Medical Research Unit at the Albert Schweitzer Hospital (HAS in Lambaréné, Gabon, were assessed for malaria. Giemsa-stained thick films for qualitative and quantitative diagnosis and enumeration of malaria pigment, or haemozoin (Hz-containing leukocytes (PCL were performed, and full blood counts (FBC were generated with a Cell Dyn 3000® instrument. Results Compared to standard light microscopy of Giemsa-stained thick films, diagnosis by platelet count only, by malaria pigment-containing monocytes (PCM only, or by pigment-containing granulocytes (PCN only yielded sensitivities/specificities of 92%/93%; 96%/96%; and 85%/96%, respectively. The platelet count was significantly lower in children with malaria compared to those without (p ® instrument detected significantly more patients with PCL (p Conclusion In the age group examined in the Lambaréné area, platelets are an excellent adjuvant tool to diagnose malaria. Pigment-containing leukocytes (PCL are more readily detected by automated scatter flow cytometry than by microscopy. Automated Hz detection by an instrument as used here is a reliable diagnostic tool and correlates with disease severity. However, clinical usefulness as a prognostic tool is limited due to an overlap of PCL numbers recorded in severe versus non-severe malaria. However, this is possibly because of the instrument detection algorithm was not geared towards this task, and data lost during processing; and thus adjusting the instrument's algorithm may allow to establish a meaningful cut-off value.

    Discovery and validation of genetic variants that influence disease severity in children with sickle cell anemia (SCA) could lead to early identification of high-risk patients, better screening strategies, and intervention with targeted and preventive therapy. We hypothesized that newly identified genetic risk factors for the general African American population could also impact laboratory biomarkers known to contribute to the clinical disease expression of SCA, including variants influencing the white blood cell count and the development of albuminuria and abnormal glomerular filtration rate. We first investigated candidate genetic polymorphisms in well-characterized SCA pediatric cohorts from three prospective NHLBI-supported clinical trials: HUSTLE, SWiTCH, and TWiTCH. We also performed whole exome sequencing to identify novel genetic variants, using both a discovery and a validation cohort. Among candidate genes, DARC rs2814778 polymorphism regulating Duffy antigen expression had a clear influence with significantly increased WBC and neutrophil counts, but did not affect the maximum tolerated dose of hydroxyurea therapy. The APOL1 G1 polymorphism, an identified risk factor for non-diabetic renal disease, was associated with albuminuria. Whole exome sequencing discovered several novel variants that maintained significance in the validation cohorts, including ZFHX4 polymorphisms affecting both the leukocyte and neutrophil counts, as well as AGGF1, CYP4B1, CUBN, TOR2A, PKD1L2, and CD163 variants affecting the glomerular filtration rate. The identification of robust, reliable, and reproducible genetic markers for disease severity in SCA remains elusive, but new genetic variants provide avenues for further validation and investigation.

    A rotary blood pump fuzzy logic flow controller without flow sensors was developed and tested in vitro. The controller, implemented in LabView, was set to maintain a flow set point in the presence of external pressure disturbances. Flow was estimated as a function of measured pump's delta P and speed, using a steady-state, nonlinear approximation. The fuzzy controller used the pump's flow estimate and delta P as feedback variables. The defuzzified control output manipulated the pump speed. Membership functions included flow error, delta P, and pump speed. Experimental runs in a mock loop (water/glycerin 3.5 cPs, 37 degrees C), using the estimated flow, were compared with those using a Transonic flow meter for nine conditions of flow and delta P (4 to 6 L/min, 150 to 350 mm Hg). Pressure disturbances generated by a servo pinch valve ranged from +/-23 to +/-47 mm Hg. Results indicated that the fuzzy controller ably regulated the flow set point to within +/-10% of the baseline even under large swings in pressure. There was no difference in controller performance between the ultrasonic flow measurement and the estimated flow calculation scenarios. These tests demonstrated that the fuzzy controller is capable of rejecting disturbances and regulating flow to acceptable limits while using a flow estimate.

    Full Text Available In this review we discuss the potential of a new procedure, termed Bronchial Thermoplasty to prevent serious consequences resulting from excessive airway narrowing. The most important factor in minimizing an asthmatic attack is limiting the degree of smooth muscle shortening. The premise that airway smooth muscle can be either inactivated or obliterated without any long-term alteration of other lung tissues, and that airway function will remain normal, albeit with reduced bronchoconstriction, has now been demonstrated in dogs, a subset of normal subjects, and mild asthmatics. Bronchial Thermoplasty may thus develop into a useful clinical procedure to effectively impair the ability for airway smooth muscle to reach the levels of pathologic narrowing that characterizes an asthma attack. It may also enable more successful treatment of asthma patients who are unresponsive to more conventional therapies. Whether this will remain stable for the lifetime of the patient still remains to be determined, but at the present time, there are no indications that the smooth muscle contractility will return. This successful preliminary experience showing that Bronchial Thermoplasty could be safely performed in patients with asthma has led to an ongoing clinical trial at a number of sites in Europe and North America designed to examine the effectiveness of this procedure in subjects with moderately severe asthma.

    Full Text Available White blood cell (WBC count has been associated with diabetic risk, but whether the correlation is independent of other risk factors has hardly been studied. Moreover, very few such studies with large sample sizes have been conducted in Chinese. Therefore, we investigated the relationship between WBC count and glucose metabolism in china. We also examined the relevant variables of WBC count. A total of 9,697 subjects (mean age, 58.0 ± 9.1 years were recruited. The subjects were classified into four groups, including subjects with normal glucose tolerance, isolated impaired fasting glucose, impaired glucose tolerance and type 2 diabetes mellitus (T2DM. We found that WBC count increased as glucose metabolism disorders exacerbated. WBC count was also positively correlated with waist hip ratio, body mass index, smoking, triglycerides, glycosylated haemoglobin A1c (HbA1c and 2-h postprandial glucose. In addition, high density lipoprotein and the female gender were inversely correlated with WBC count. In patients with previously diagnosed T2DM, the course of T2DM was not correlated with WBC count. Our findings indicate that elevated WBC count is independently associated with worsening of glucose metabolism in middle-aged and elderly Chinese. In addition, loss of weight, smoking cessation, lipid-modifying therapies, and control of postprandial plasma glucose and HbA1c may ameliorate the chronic low-grade inflammation.

    Few studies have assessed the relationship between a subnormal inflammatory status and metabolic syndrome (MS). We therefore designed a cross-sectional and 5-year cohort study to evaluate how a subnormal peripheral blood leukocyte count is related to MS. Participants were recruited from Tianjin Medical University General Hospital-Health Management Centre. Both a baseline cross-sectional (n = 46,179) and a prospective assessment (n = 13,061) were performed. Participants without a history of MS were followed up for 5 years. Leukocyte counts and MS components were assessed at baseline and yearly during the follow-up. Adjusted logistic and Cox proportional hazards regression models were used to assess relationships between the categories of leukocyte counts and MS. The subnormal leukocyte counts group (1,100–3,900 cells/mm3) had the lowest prevalence and incidence of MS. The odds ratio and hazard ratio (95% confidence interval) of the highest leukocyte counts were 1.98 (1.57–2.49) and 1.50 (1.22–1.84) (both P for trend <0.0001), respectively, when compared to the subnormal leukocyte counts group after adjusting for potential confounders. This study has shown that subnormal leukocyte counts are independently related to the lowest prevalence and incidence of MS. The findings suggest that it is necessary to restudy and discuss the clinical or preventive value of subnormal leukocyte counts. PMID:24876672

    Blood bank regulatory agencies including the Drug and Cosmetics Act (DCA) of India do not mandate a predonation platelet count in whole blood donation. Mandating such practice will definitely optimize the quality of random donor platelets (RDP) in terms of platelet yield and patient therapeutic benefit. We observed poor platelet yield in RDP concentrates prepared at our center with a significant number not meeting the DCA guideline of ≥ 4.5 × 10(10) per bag processed from 450 ml of whole blood. Therefore we planned this study to evaluate the pre-donation hematological values in our blood donor population and effect of these values on the quality of platelet concentrates. The prospective study included 221 blood donors eligible for donating 450 ml of whole blood (WB). Following the departmental standard operating procedure (SOP) RDPs were prepared using the 'Top & Bottom' quadruple bag system and automated component extractor. Quality of RDP was assessed as per departmental protocol. All results were recorded and subsequently transcribed to SPSS working sheet. A significant (pblood counts has been observed after WB donation. Mean donor Hb and platelets reduced by 0.72 g/dl and 22.1 × 10(6)/ml respectively. Quality of RDPs in terms of platelet yield was significantly better (pcount was >200 × 10(6)/ml. Although platelet yield significantly correlated with the donor platelet count however quality of RDPs in terms of red cell contamination showed no correlation with the donor hematocrit. Platelet yield in random donor platelets is a concern in Eastern India. A platelet yield of 4.5 × 10(10) per bag as mandated by the DCA of India was only achieved when the donor platelet count was >200 × 10(6)/ml. Posttransfusion platelet recovery (PPR) was unsatisfactory in the transfused patient. Introduction of pre-donation platelet count in whole blood donation will maximize donor safety and optimize patient platelet transfusion management.

    Asthma is an inflammatory disease of the airways clinically characterised by recurrent bronchial obstructions at least partially reversible. Recent epidemiologic data suggest that asthmatics have an increased rate of decrease of their expiratory volumes during life. This irreversible lung function impairment is associated with fundamental structural changes of the bronchial wall in terms of conjunctive tissue and smooth muscle composition. We describe these changes and explore the different mechanisms proposed to explain these structural modifications. We also review their consequences in terms of bronchial physiology and their potential influence on bronchial hyperresponsiveness.

    Full Text Available AIMS AND OBJECTIVES: To observe the change in haemoglobin level and leukocyte counts in the cord blood of neonates born of hypertensive mothers by comparing it with the haemoglobin level and leukocyte counts of cord blood of neonates born of healthy mothers. MATERIALS AND METHODS: A Prospective observational study was carried out among thirty newborns of hypertensive mothers and thirty apparently healthy newborns of normotensive mothers in, West Tripura. Haemoglobin level was estimated by Sahli’s method and total Leukocyte count (TLC was done using Improved Neubauer’s Counting chamber. Absolute counts were obtained by doing Differential Leukocyte Count (DLC and the value obtained from TLC. For DLC, slides were stained with Leishman’s stain. Statistical analysis was carried out using t-test for the comparison of differences of the means by SPSS 15.0. RESULTS: Haemoglobin level was found to be significantly higher in the study group as compared to control group. Leukopenia, neutropenia, lymphopenia and anaemia were found in 10%, 3.3%, 13.3% and 23.3% subjects respectively in the study group. Leukopenia, lymphopenia and anaemia were also found in 6.6%, 10% and 56.6% subjects respectively in the control group. CONCLUSION: A significant haematological changes occur in the newborns of hypertensive mothers and further research need to be carried out to find the relation between hypertensive disorders and changes in haematological parameters of the newborns.

    Radioactive iodine (RAI) is considered to be related with hematologic changes. This study aimed to evaluate influence of the first RAI ablation on peripheral complete blood count (CBC) in patients with differentiated thyroid cancer (DTC).Data of CBC at baseline and 6 months after RAI were obtained in 385 patients with DTC with approximately 3700 MBq I (ranging 2220-7585 MBq). Further comparison was done in 196 patients with 1-month postablation data available. Routine blood examinations were performed to determine impact of RAI on white blood cell (WBC), red blood cell (RBC), hemoglobin, platelet, neutrophil, lymphocyte, and monocyte in both sexes. Continuous variables were compared by paired t tests and independent samples t test, and categorical variables were compared by chi-square analysis. Data with repeated measurements were analyzed by analysis of variance.The first RAI after thyroidectomy was associated with mild, yet significant declines in WBC, platelet, and lymphocyte, which persisted for 6 months. One month after RAI, significant declines were found in all CBC, including RBC and hemoglobin (all P < 0.05). While CBC partly recovered 6 months after RAI, this follow-up CBC still demonstrated significant declines in WBC, platelet, and lymphocyte (all P < 0.05) without gender differences. Significant rises in RBC and hemoglobin in males and females were found. The decline of platelet in females was more obvious than in males at 3700 to 4440 MBq of RAI. On the contrary, the rises of RBC and hemoglobin in males were higher than in females. There were no significant complications during the follow-up.WBC and platelet decreased obviously 1 month after RAI. While they partly recovered 6 months after RAI, they were still lower than the baseline. However, RBC and hemoglobin transiently decreased at 1 month and then increased to levels even higher than baseline 6 months later. At 3700 to 4440 MBq of RAI, the decline of platelet in females was more obvious

    The erythrocyte sedimentation rate (ESR) and white blood cell (WBC) count are frequently obtained in the work-up of post-operative fever. However, their diagnostic utility depends upon comparison with normative peri-operative trends which have not yet been described. The purpose of this study is to define a range of erythrocyte sedimentation rates and white blood cell counts following spinal instrumentation and fusion in non-infected patients. Seventy-five patients underwent spinal instrumentation and fusion. The erythrocyte sedimentation rate and white blood cell count were recorded pre-operatively, at 3 and 7 days post-operatively, and at 1 and 3 months post-operatively. Both erythrocyte sedimentation rate and white blood cell count trends demonstrated an early peak, followed by a gradual return to normal. Peak erythrocyte sedimentation rates occurred within the first week post-operatively in 98% of patients. Peak white blood cell counts occurred with the first week in 85% of patients. In the absence of infection, the erythrocyte sedimentation rate was abnormally elevated in 78% of patients at 1 month and in 53% of patients at 3 months post-operatively. The white blood cell count was abnormally elevated in only 6% of patients at 1 month post-operatively. Longer surgical time was associated with elevated white cell count at 1 week post-operatively. The fusion of more vertebral levels had a negative relationship with elevated erythrocyte sedimentation rate at 1 week post-operatively. The anterior surgical approach was associated with significantly lower erythrocyte sedimentation rate at 1 month post-operatively and with lower white cell count at 1 week post-operatively. In non-infected spinal fusion surgeries, erythrocyte sedimentation rates are in the abnormal range in 78% of patients at 1 month and in 53% of patients at 3 months post-operatively, suggesting that the erythrocyte sedimentation rate is of limited diagnostic value in the early post

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    Full Text Available This experiment was carried out to assess the effect of Azadirachta indica, Newbouldia laevis and Spondias mombin leaves on rumen fermentation, microbial count and blood urea nitrogen (BUN of West African Dwarf (WAD goats. Sixteen WAD bucks (11.6 ? 0.9 kg in body weight were allocated to 4 treatments: 1 Control and 2 40 g/day of Azadirachta indica, 3 40 g/day of Newbouldia laevis and 4 40 g/day of Spondias mombin leaves arranged in a completely randomised design. The ground leaves were included in concentrate diets served on dry matter basis at 2% of body weight while Panicum maximum was fed ad libitum. The control diet had no tree leaves. Data were collected on chemical composition, rumen fermentation and microbial ecology, and BUN. Saponin was highest (P < 0.05 in S. mombin (8.14% while A. indica and N. laevis had 5.78% and 1.56%, respectively. Rumen ammonia nitrogen was least (P < 0.05 in goats fed A. indica (8.35 mg/dL while the highest (P < 0.05 total volatile fatty acid (TVFA was obtained from goats fed S. mombin with 125.51 mM. Goats fed N. laevis yielded the highest (P < 0.05 acetate with 70.65 mol/100 mol while propionate production was highest (P < 0.05 in the rumen of goats fed S. mombin (27.15 mol/100 mol. Viable bacteria count was lowest (P < 0.05 in rumen of goats fed A. indica (3.95?1012 cfu/ml while the least (P < 0.05 protozoa population was obtained from the rumen of bucks fed S. mombin (4.18?109 cfu/ml. All goats in the treatments containing tree leaves had higher (P < 0.05 and a rapid increase in BUN between 0 and 6 h post feeding when compared with the Control. It is concluded that feeding ground leaves of S. mombin to goats increases rumen total volatile fatty acid and propionate production and reduces the protozoa population.

    Full Text Available This study was designed to investigate the possible adverse effects that may be induced by once-daily therapeutic doses of either glucosamine sulfate or glucosamine/chondroitin sulfate administered orally to rats for 30 days on blood cells (RBCs, WBCs and platelets counts. Forty three white healthy adult Albino rats of both sexes were selected randomly for this study. They were divided into three groups (І, ІІ, ІІІ. Group І received 0.05 ml distilled water, group ІІ received once daily therapeutic dose of glucosamine sulphate and group ІІІ received once daily therapeutic dose of glucosamine sulphate/chondroitin sulphate orally. The treatment period was for 30 days. At day 31, the animals were subjected to light ether anaesthesia and blood was withdrawn from the eye by retro-orbital puncture for the estimation of blood cells (RBCs, WBCs and platelets count. Treatment with single daily therapeutic dose of either GS alone or GS/CS for 30 days on blood cells count in rats produced a non significant change in RBCs counts compared to control and to each other. There were no statistically significant differences in total WBCs count at day 31 in animals administered once daily therapeutic dose of either GS or GS/CS orally compared to control group. In contrast, there was a statistically significant elevation in total WBCs count in GS/CS- treated rats compared to that in the GS-treated rats. The results of this study also showed that there was statistically significant decrease in neutrophils percentage in both drug treatment groups compared to control group. A statistically significant reduction in the percentage of monocytes was observed in GS/CS group compared to the corresponding percentage in animals of control group; while, there were non-significant differences in the percentage of monocytes in GS treated rats compared to that in the control group. There were no significant differences in the percentage of monocytes at day 31 of GS

    This study was conducted to evaluate the prognostic significance of pre-treatment complete blood cell count (CBC), including white blood cell (WBC) differential, in epithelial ovarian cancer (EOC) patients with primary debulking surgery (PDS) and to develop nomograms for platinum sensitivity, progression-free survival (PFS), and overall survival (OS). We retrospectively reviewed the records of 757 patients with EOC whose primary treatment consisted of surgical debulking and chemotherapy at Samsung Medical Center from 2002 to 2012. We subsequently created nomograms for platinum sensitivity, 3-year PFS, and 5-year OS as prediction models for prognostic variables including age, stage, grade, cancer antigen 125 level, residual disease after PDS, and pre-treatment WBC differential counts. The models were then validated by 10-fold cross-validation (CV). In addition to stage and residual disease after PDS, which are known predictors, lymphocyte and monocyte count were found to be significant prognostic factors for platinum-sensitivity, platelet count for PFS, and neutrophil count for OS on multivariate analysis. The area under the curves of platinum sensitivity, 3-year PFS, and 5-year OS calculated by the 10-fold CV procedure were 0.7405, 0.8159, and 0.815, respectively. Prognostic factors including pre-treatment CBC were used to develop nomograms for platinum sensitivity, 3-year PFS, and 5-year OS of patients with EOC. These nomograms can be used to better estimate individual outcomes.

    1. The oxygen consumption of blood of normal individuals, when the hemoglobin is saturated with oxygen, is practically zero within the limits of experimental error of the microspirometer used. 2. The oxygen consumed in a microspirometer by the blood of patients with chronic myelogenous leucemia with a high white blood cell count, and of one with leucocytosis from sepsis, was proportional to the number of adult polymorphonuclear neutrophils in the blood. 3. No correlation could be made between the rate of oxygen absorption and the total number of white blood cells in the blood, or the total number of immature cells, or the number of red blood cells, or the amount of oxyhemoglobin. 4. The blood of patients with chronic myelogenous leucemia continued to use oxygen in the microspirometer longer than that of normal individuals, and the hemoglobin, in the leucemic bloods, became desaturated even though exposed to air. 5. In blood in which the bulk. of the cells were immature and the mature cells few, the oxygen consumption was lower than in blood in which the mature cells predominated. The rate of oxygen consumption of the immature cells was relatively low as compared to the mature. 6. The slower rate of oxygen absorption by the immature leucocytes in chronic myelogenous leucemia as compared to the mature cells, places them, in accord with Warburg's reports, in the class of the malignant tissues in this respect rather than in the group of young or embryonic cells.

    Full Text Available Background: Most lantern mantles contain low levels of radioactive thorium. Although radioactive lantern mantles present a minimal radiation health hazard, it is generally believed when inhaled or ingested, it can be dangerous. The purpose of this study was to assess the effect of short term exposure to radioactive lantern mantle on serum cortisol level and blood count.Materials and Methods: This experimental study was conducted in 2007-2009 in the school of medicine of Rafsanjan University of Medical Sciences. Twenty eight rats were divided randomly into two groups of 14 animals each. The first group was exposed to 600 mg burned radioactive lantern mantle powder (activity of 800Bq for 24 hours and inhaled radon released from mantles. The second group was exposed to non-radioactive lantern mantle powder at the same interval. Paired t-test was used to evaluate the difference in the means of cortisol and blood cell count in both groups. P<0.05 was considered as the significance level.Results: Short term exposure of animals to radioactive lantern mantle powder led to a statistically significant decreased cortisol level, while no statistically significant decrease was found in animals that were exposed to non-radioactive mantle powder. Furthermore, a significant reduction was shown in post-exposure counts of WBC in the case group.Conclusions: Despite alteration of serum cortisol level, this study could not show stimulatory effects in some blood counts

    Epigenome-wide association studies of prenatal exposure to different environmental factors are becoming increasingly common. These studies are usually performed in umbilical cord blood. Since blood comprises multiple cell types with specific DNA methylation patterns, confounding caused by cellular heterogeneity is a major concern. This can be adjusted for using reference data consisting of DNA methylation signatures in cell types isolated from blood. However, the most commonly used reference data set is based on blood samples from adult males and is not representative of the cell type composition in neonatal cord blood. The aim of this study was to generate a reference data set from cord blood to enable correct adjustment of the cell type composition in samples collected at birth. The purity of the isolated cell types was very high for all samples (>97.1%), and clustering analyses showed distinct grouping of the cell types according to hematopoietic lineage. We explored whether this cord blood and the adult peripheral blood reference data sets impact the estimation of cell type composition in cord blood samples from an independent birth cohort (MoBa, n = 1092). This revealed significant differences for all cell types. Importantly, comparison of the cell type estimates against matched cell counts both in the cord blood reference samples (n = 11) and in another independent birth cohort (Generation R, n = 195), demonstrated moderate to high correlation of the data. This is the first cord blood reference data set with a comprehensive examination of the downstream application of the data through validation of estimated cell types against matched cell counts.

    Increasing evidence has indicated that insulin resistance is associated with inflammation. However, few studies have investigated the association between white blood cell (WBC) count and insulin resistance, as measured by a homeostasis model assessment of insulin resistance (HOMA-IR) in a general pediatric population. This study aimed to examine the association between WBC count and insulin resistance as measured by HOMA-IR in a nationally representative sample of children and adolescents. In total, 2761 participants (1479 boys and 1282 girls) aged 10-18 years were selected from the 2008-2010 Korean National Health and Nutrition Examination Survey. Insulin resistance was defined as a HOMA-IR value greater than the 90th percentile. The odds ratios and 95% confidence intervals for insulin resistance were determined using multiple logistic regression analysis. The mean values of most cardiometabolic variables tended to increase proportionally with WBC count quartiles. The prevalence of insulin resistance significantly increased in accordance with WBC count quartiles in both boys and girls. Compared to individuals in the lowest WBC count quartile, the odds ratio for insulin resistance for individuals in the highest quartile was 2.84 in boys and 3.20 in girls, after adjusting for age, systolic blood pressure, body mass index, and waist circumference. A higher WBC count was positively associated with an increased risk of insulin resistance in Korean children and adolescents. This study suggests that WBC count could facilitate the identification of children and adolescents with insulin resistance.

    Inflammatory processes are implicated in the development and progression of age-related macular degeneration (AMD). However, there are limited data on longitudinal associations between systemic markers of inflammation and AMD. The authors examined the prospective relation between the circulating white blood cell (WBC) count and early and late AMD in a population-based cohort of 3,654 participants, aged 49-97 years, in the Blue Mountains region, Australia. The main outcome of interest was the 10-year incidence of early and late AMD among individuals free from corresponding disease at the baseline (1992-1994). An elevated baseline WBC count was associated with early AMD incidence, independent of smoking and other major confounders. The multivariable relative risk comparing tertile 3 of WBC count (>6.7 x 10(9) cells/liter) with tertile 1 (count and early AMD was present consistently in analyses of different early AMD lesions, including incident pigmentary abnormalities and soft indistinct/reticular drusen. Moreover, this association persisted in subgroup analyses by gender and smoking. An elevated WBC count at baseline was not consistently associated with late AMD incidence. This study provides population-based evidence supporting a longitudinal association between the circulating WBC count, a widely available marker of inflammation, and incidence of early AMD.

    The metabolic syndrome is highly prevalent in patients with schizophrenia, and is associated with a state of chronic, low-grade inflammation. Schizophrenia is also associated with increased inflammation, including aberrant blood levels of pro-inflammatory cytokines and high-sensitivity C-reactive protein (hsCRP). The purpose of this study is to investigate the relationship between total and differential white blood cell (WBC) counts, hsCRP, and the metabolic syndrome in patients with schizophrenia and related non-affective psychoses. Fifty-nine inpatients and outpatients age 18-70 with non-affective psychotic disorders and 22 controls participated in this cross-sectional study. Subjects had a fasting blood draw between 8 and 9 am for glucose, lipids, total and differential WBC counts, and hsCRP. Vital signs and anthropometric measures were obtained. Patients with non-affective psychosis and the metabolic syndrome had significantly higher total WBC counts, monocytes, and hsCRP levels than patients without the metabolic syndrome (p≤0.04 for each). In binary logistic regression analyses, after controlling for potential confounding effects of age, race, sex, age at first hospitalization for psychosis, parental history of diabetes, smoking, and psychotropic medications, total WBC count, monocytes, and hsCRP were significant predictors of metabolic syndrome in patients (p≤0.04 for each). hsCRP was also a significant predictor of increased waist circumference and triglycerides in patients (p≤0.05 for each). Our findings suggest that measurement of total and differential WBC counts and hsCRP blood levels may be germane to the clinical care of patients with schizophrenia and related disorders, and support an association between inflammation and metabolic disturbance in these patients.

    Successful bronchial healing after a bronchoplastic procedure mainly depends on bronchial circulation at the anastomostic site. We developed a bronchial fluorescein angiography (B-FAG) technique for visualizing circulation on the bronchial surface. The technique was evaluated in animals. Fluorescein was used as a contrast agent and an autofluorescence imaging (AFI) bronchoscope as a detector. The left main pulmonary artery (PA) and main bronchus of 10 pigs were isolated. After transection of the left main bronchus and bronchial arteries and re-anastomosis of the bronchus, the pigs were randomly divided into two groups: the PA- group (n = 5), in which the pulmonary artery was transected; and the PA+ group (n = 5), in which the pulmonary artery was preserved. Following intravenous injection of fluorescein, the distal anastomotic site was observed for 30 min with autofluorescence imaging bronchoscopy. Bronchial specimens sampled 2 days after the surgical intervention were histologically evaluated. In the PA- group, there was no fluorescein enhancement in the distal bronchus throughout the observation time. However, enhancement, which turned the bronchial surface from magenta to bright green, was clearly observed in less than 207 ± 102.5 s in the PA+ group. The enhancement status detected by bronchial fluorescein angiography was related to the extent of tissue damage, as was proven histologically in the acute healing stage. Bronchial fluorescein angiography clearly visualized the circulatory status promptly after the anastomosis procedure at the central bronchus. This technique is a potentially practical approach to predict ischaemic airway complications following bronchial anastomosis. © The Author 2016.

    It remains controversial whether adjuvant therapy should be delivered to pathological T3N0M0 rectal cancer without neoadjuvant chemoradiotherapy. Thus identification of patients at high risk is of particular importance. Herein, we aimed to evaluate whether the absolute peripheral blood monocyte count can stratify the pathological T3N0M0M0 rectal cancer patients in survival. A total of 270 pathological T3N0M0 rectal cancer patients with total mesorectal excision-principle radical resection were included. The optimal cut-off value of preoperative monocyte count was determined by receiver operating characteristic curve analysis. Overall survival and disease-free survival between low- and high-monocyte were estimated by Kaplan-Meier method and Cox regression model. The optimal cut-off value for monocyte count was 595 mm(3). In univariate analysis, patients with monocyte counts higher than 595/mm(3) had significantly inferior 5-year overall survival (79.2 vs 94.2 %, P = 0.006) and disease-free survival (67.8 vs 86.0 %, P count remained to be associated with poor overall survival (HR = 2.55, 95 % CI 1.27-5.10; P = 0.008) and disease-free survival (HR = 2.63, 95 % CI 1.48-4.69; P = 0.001). Additionally, the significant association of monocyte count with disease-free survival was hardly influenced in the subgroup analysis, whereas this correlation was restricted to the males and patients with normal carcinoembryonic antigen (CEA) level (count is independently predictive of worse survival of pathological T3N0M0 rectal cancer patients without neoadjuvant chemoradiotherapy. Postoperative adjuvant therapy might be considered for patients with high-monocyte count.

    Current flow-based blood counting devices require expensive and centralized medical infrastructure and are not appropriate for field use. In this paper we report a method to count red blood cells, white blood cells as well as platelets through a low-cost and fully-automated blood counting system. The approach consists of using a compact, custom-built microscope with large field-of-view to record bright-field and fluorescence images of samples that are diluted with a single, stable reagent mixture and counted using automatic algorithms. Sample collection is performed manually using a spring loaded lancet, and volume-metering capillary tubes. The capillaries are then dropped into a tube of pre-measured reagents and gently shaken for 10-30 seconds. The sample is loaded into a measurement chamber and placed on a custom 3D printed platform. Sample translation and focusing is fully automated, and a user has only to press a button for the measurement and analysis to commence. Cost of the system is minimized through the use of custom-designed motorized components. We performed a series of comparative experiments by trained and untrained users on blood from adults and children. We compare the performance of our system, as operated by trained and untrained users, to the clinical gold standard using a Bland-Altman analysis, demonstrating good agreement of our system to the clinical standard. The system's low cost, complete automation, and good field performance indicate that it can be successfully translated for use in low-resource settings where central hematology laboratories are not accessible.

    Full Text Available El traumatismo torácico es una entidad patológica emergente, relacionada con accidentes automovilísticos. La lesión más frecuente es la fractura costal. Dependiendo de su gravedad, éste puede provocar tórax volante, contusión cardíaca, lesiones vasculares u otras alteraciones. La ruptura bronquial se observa ocasionalmente en traumatismos torácicos cerrados, y por lo general tiene lugar en el tronco principal del árbol tráqueo-bronquial. Su diagnóstico y manejo inicial representan un problema mayor. Los signos clásicos son la persistencia de neumotórax y flujo masivo de aire a través del drenaje torácico; sin embargo también hay casos que no son típicos.

    Full Text Available Background: Atrial fibrillation (AF occurs in 30% patients on the second or third day post operation; therefore, it is the most prevalent and complicated arrhythmia after open heart surgery. White blood cell (WBC count seems to be most significantly associated with cardiovascular disorders. This study was designed to evaluate the exact relationship between preoperative WBC count and post-Coronary artery bypass graft (CABG AF in patients with severe left ventricle (LV dysfunction who underwent elective off-pump coronary artery bypass. Methods: This study was conducted on 104 patients from among 400 patients with severe LV dysfunction undergoing elective off-pump CABG surgery from February 2011 to February 2012, in Afshar Cardiovascular Center, Yazd, Iran. Patients with emergency surgery, unstable angina creatinine higher than 2.0 mg/dL, malignancy, or immunosuppressive disease were excluded. Preoperative serological tests of the participants, such as WBC counts, were saved in their medical dossiers. Of the 400 patients undergoing CABG, AF was found in 54 cases; these 54 male patients formed the experimental group and 60 other patients in the intensive care unit (ICU and hospital stay without postoperative AF were part of the control group. Results: The average age of the patients was 68.5±12.8 years. WBC counts in patients with and without AF three days before surgery were 12,340±155 and 8,950±170, respectively. On surgical day, WBC counts in the patients with and without AF were 13,188±140 and 9,145±255, respectively (P value three days before surgery: 0.04; P value on surgical day: 0.01. Of the 54 male patients with postoperative AF (POAF, duration of AF was more in cases with elevated WBC count (12,000-14,000 than in those with lower elevated WBC count (10,000-12,000 ( P=0.025, but there was no relationship between frequency of recurrence of AF and grading of elevation of WBC count ( P=0.81.

    Inflammation is an important underlying mechanism in the pathogenesis of atherosclerosis, and an elevated resting heart rate underlies the process of atherosclerotic plaque formation. We hypothesized an association between resting heart rate and subclinical inflammation. Resting heart rate was recorded at baseline in the KoGES-ARIRANG (Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population) cohort study, and was then divided into quartiles. Subclinical inflammation was measured by white blood cell count and high-sensitivity C-reactive protein. We used progressively adjusted regression models with terms for muscle mass, body fat proportion, and adiponectin in the fully adjusted models. We examined inflammatory markers as both continuous and categorical variables, using the clinical cut point of the highest quartile of white blood cell count (≥7,900/mm(3)) and ≥3 mg/dL for high-sensitivity C-reactive protein. Participants had a mean age of 56.3±8.1 years and a mean resting heart rate of 71.4±10.7 beats/min; 39.1% were men. In a fully adjusted model, an increased resting heart rate was significantly associated with a higher white blood cell count and higher levels of high-sensitivity C-reactive protein in both continuous (P for trend heart rate is associated with a higher level of subclinical inflammation among healthy Korean people.

    Full Text Available Introduction. Bronchial carcinoids belong to a rare type of lung tumors. If they do not expose outstanding neuroendocrine activity, they develop without clearly visible symptoms. They are often detected during a routine examination. According to their clinical pathological features, they are divided into typical and atypical tumors. Typical bronchial carcinoids metastasize to distant organs very rarely. Localized forms are effectively treated by surgery. The methods of conservative treatment should be applied in other cases. Case report. We presented a 65-year-old patient with carcinoid lung tumor detected by a routine examination. Additional analysis (chest X-ray, computed tomography of the chest, ultrasound of the abdomen, skeletal scintigraphy, bronhoscopy, histopathological analysis of the bioptate of bronchial tumor, as well as bronchial brushing cytology and immunohistochemical staining performed with markers specific for neuroendocrine tumor proved a morphologically typical lung carcinoid with dissemination to the liver and skeletal system, which is very rarely found in typical carcinoids. Conclusion. The presented case with carcinoid used to be showed morphological and pathohistological characteristics of typical bronchial carcinoid. With its metastasis to the liver and skeletal system it demonstrated unusual clinical course that used to be considered as rare phenomenon. Due to its frequent asymptomatic course and varied manifestation, bronchial carcinoid could be considered as a diagnostic challenge requiring a multidisciplinary approach.

    Massive hemoptysis is one of the most dreaded of all respiratory emergencies and can have a variety of underlying causes. It is mostly caused by bleeding from bronchial circulation. Bronchial artery embolization is now considered to be the treatment of choice for acute massive hemoptysis. Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis. However, nonbronchial systemic arteries can be a significant source of massive hemoptysis and a cause of recurrence after successful BAE. So knowledge of the bronchial artery anatomy, together with an understanding of the pathophysiologic features of massive hemoptysis, are essential for planning and performing BAE in affected patients. In addition, interventional radiologists should be familiar with the techniques, results, efficacy, safety and possible complications of BAE and with the characteristics of the various embolic agents. Bronchial arterial catheterisation in human via a percutaneous approach has been practiced for 32 years (1973) in the world and 20 years (1986) in China, initially for direct chemotherapy treatment for bronchial malignancies and then for the embolization of patients with massive haemoptysis. A review of clinical experience to evaluate technique,embolic materials,outcome and complications of BAE is presented.

    Full Text Available The study involved 30 students with severe bronchial asthma and 30 children with moderate to severe course. Patients with severe bronchial asthma revealed a clear tendency to increase the relative content of interleukin 4 in peripheral blood, which indirectly indicates the severity of inflammation in the bronchi. Almost every second child suffering from severe bronchial asthma reported an increase in the concentration of immunoglobulin E (more than 545.3 IU/ml, and the odds ratio was 1.9 (95% CI 1.1–3.4. In the group of patients with severe bronchial asthma, cases of increased skin sensitivity to household allergens were significantly more frequent compared to the second group. Thus, the size of hyperemia over 15.0 mm was recorded in 81.5 % of children of the first group and only in 51.9 % of persons (Pϕ < 0.05 in the second one. Clinical and epidemiological risk and diagnostic value of individual indicators of atopic reactivity were determined to verify the phenotype of severe bronchial asthma.

    Full Text Available Background: Radiotherapy is frequently used in treatment approaches of pelvic malignancies. Nevertheless, it has some known systemic effects on blood cells and the immune system that possibly results in their susceptibility to infection. Probiotics are live microbial food ingredients that provide a health advantage to the consumer. Honey has prebiotic properties. The aim of this clinical trial was to investigate probable effects of probiotic or probiotics plus honey on blood cell counts and serum IgA levels in patients receiving pelvic radiotherapy. Materials and Methods: Sixty-seven adult patients with pelvic cancer were enrolled. Patients were randomized to receive either: (1 Probiotic capsules (including: Lactobacillus casei, Lactobacillus acidophilus, Lactobacillus rhamnosus, Lactobacillus bulgaricus, Bifidobacterium breve, Bifidobacterium longum, and Streptococcus thermophiles (n = 22, (2 probiotic capsules plus honey (n = 21 or (3 placebo capsules (n = 24 all for 6 weeks. Blood and serum samples were collected for one week before radiotherapy and 24-72 h after the end of radiotherapy. Results: White blood cells (WBC, red blood cells (RBC, platelet counts, and serum IgA level were not significantly changed in patients taking probiotic (alone or plus honey during pelvic radiotherapy. The mean decrease in RBC count was 0.52, 0.18, and 0.23 × 10 6 cells/μL, WBC count was 2.3, 1.21, and 1.34 × 10 3 cells/μL and platelet count was, 57.6, 53.3, and 66.35 × 10 3 cells/μL for the probiotic, probiotic plus honey, and placebo groups, respectively. The mean decrease of serum IgA was 22.53, 29.94, and 40.73 mg/dL for the probiotic, probiotic plus honey, and placebo groups, respectively. Conclusion: The observed nonsignificant effect of probiotics may be in favor of local effects of this product in the gut rather than systemic effects, however, as a trend toward a benefit was indicated, further studies are necessary in order to extract effects of

    Full Text Available The paper analyzes the performance of extracranial hemodynamics — volumetric and linear blood flow velocity, the state of peripheral vascular resistance and vascular reactivity at ultrasound Doppler examination of the internal carotid and vertebral arteries of 66 children with bronchial asthma and and 22 healthy children. Development of regional hypoperfusion in vertebrobasilar zone, disorders of the carotid system are proven, but these changes have not led to a decrease in the volumetric blood flow velocity in both internal carotid arteries and the total volume of cerebral blood flow, indicating the compensation of hemodynamic disturbances due to the influence of constant rates in volumetric blood flow in the carotid system. Changes in parameters of extracranial hemodynamics in children with bronchial asthma should be considered as predictor of cerebrovascular complications in this group of patients.

    Lung transplantation has resulted in dramatic functional improvement in patients with end-stage pulmonary diseases. Among the complications of lung transplantation are dehiscence and stenosis at the site of the bronchial or tracheal anastomosis. In this case report, we describe a single lung transplant recipient in whom partial bronchial dehiscence, followed by exuberant growth of granulation tissue, resulted in obstruction of the bronchial lumen. After mechanical dilation failed to produce lasting relief of bronchial obstruction, a novel approach to this problem was successfully employed: YAG laser phototherapy was used to remove obstructing granulation tissue, followed by application of a preparation derived from autologous blood platelets to promote epithelialization of the bronchial anastomosis. The bronchus remains patent and fully epithelialized six months after therapy.

    A 53-year-old man with a history of blood transfusion at the age of 20 was admitted to our hospital because of liver dysfunction. He had bronchial asthma when he was 18 years old, which naturally resolved within 2 years. However, his bronchial asthma recurred at the age of 45 and was treated with oral theophylline. He was diagnosed as having chronic hepatitis C based on the histological and clinical findings, and then interferon (IFN) therapy was administered. The frequency of bronchial asthma attack was gradually decreasing after IFN therapy with marked improvement of hypereosinophilia. He achieved sustained viral response (SVR) and his bronchial asthma did not worsen even after the cessation of IFN. Hepatitis C virus (HCV) infection and IFN therapy were considered in the remission of asthma in this case. HCV infection could be the cause of bronchial asthma, especially in patients with late appearance of asthma.

    A close anatomical and functional relationship between superior and inferior airways is well documented. A typical example is offered by the close relationship between allergic rhinitis and asthma whose close connection is documented by epidemiological and pathological data. The mechanisms which can explain this phenomenon are not fully known but naso-bronchial reflexes, mouth-breathing due to nasal obstruction and aspiration of nasal secretions seem all to be important. Moreover it has been recently proved that the treatment of rhinitis can improve the concomitant asthma thus confirming their relationship. Another less frequent association is between sinusitis and asthma. Such a connection seems to be frequent in patients suffering of atopic rhinitis but also in patients presenting a nasal obstruction of different nature such as deviations of the nasal septum, adenoid hypertrophy etc. Also in this case a correct medical or surgical treatment of sinusitis can improve asthma symptomathology. Finally a classic example of involvement of superior and inferior airways is represented by the syndrome of ASA intolerance. These patients in fact initially complain of rhinitis which afterwards is complicated by the onset of nasal polyposis and asthma which can prove clinically very severe. Nowadays, anyway, there is no evidence that the treatment of rhinitis or polypectomy can improve the clinical course of asthma. In conclusion, diseases of superior and inferior airways must be considered in strict connection and need the same global treatment.

    Eosinophilia may represent an early paraclinical sign of malignant disease and a host anti-tumor effect. The association between eosinophilia and the development of solid tumors has never before been examined in an epidemiological setting. The aim of the present study was to investigate eosinophilia in routine blood samples as a potential biomarker of solid tumor development in a prospective design. From the Copenhagen Primary Care Differential Count (CopDiff) Database, we identified 356 196 individuals with at least one differential cell count (DIFF) encompassing the eosinophil count during 2000-2007. From these, one DIFF was randomly chosen and categorized according to no (eosinophilia. From the Danish Civil Registration System and the Danish Cancer Registry we ascertained all-cause death and solid tumors within the first three years following the DIFF. Using multivariable logistic regression, odds ratios (OR) were calculated and adjusted for previous eosinophilia, sex, age, year, month, C-reactive protein, previous cancer and Charlson's Comorbidity Index. The risk of bladder cancer was increased with mild eosinophilia [OR 1.93 (CI 1.29-2.89), p = 0.0013]. No associations with eosinophilia were observed for the remaining solid cancers. We demonstrate that eosinophilia in routine blood samples associates with an increased risk of bladder cancer. Our data emphasize that additional preclinical studies are needed in order to shed further light on the role of eosinophils in carcinogenesis, where it is still unknown whether the cells contribute to tumor immune surveillance or neoplastic evolution.

  1. Erythrocytes and the regulation of human skeletal muscle blood flow and oxygen delivery: role of erythrocyte count and oxygenation state of haemoglobin.

    Blood flow to dynamically contracting myocytes is regulated to match O(2) delivery to metabolic demand. The red blood cell (RBC) itself functions as an O(2) sensor, contributing to the control of O(2) delivery by releasing the vasodilators ATP and S-nitrosohaemoglobin with the offloading of O(2) from the haemoglobin molecule. Whether RBC number is sensed remains unknown. To investigate the role of RBC number, in isolation and in combination with alterations in blood oxygenation, on muscle and systemic perfusion, we measured local and central haemodynamics during one-legged knee-extensor exercise ( approximately 50% peak power) in 10 healthy males under conditions of normocythaemia (control), anaemia, anaemia + plasma volume expansion (PVX), anaemia + PVX + hypoxia, polycythaemia, polycythaemia + hyperoxia and polycythaemia + hypoxia, which changed either RBC count alone or both RBC count and oxyhaemoglobin. Leg blood flow (LBF), cardiac output (Q) and vascular conductance did not change with either anaemia or polycythaemia alone. However, LBF increased with anaemia + PVX (28 +/- 4%) and anaemia + PVX + hypoxia (46 +/- 6%) and decreased with polycythaemia + hyperoxia (18 +/- 5%). LBF and Q with anaemia + PVX + hypoxia (8.0 +/- 0.5 and 15.8 +/- 0.7 l min(-1), respectively) equalled those during maximal knee-extensor exercise. Collectively, LBF and vascular conductance were intimately related to leg arterial-venous (a-v) O(2) difference (r(2)= 0.89-0.93; P < 0.001), suggesting a pivotal role of blood O(2) gradients in muscle microcirculatory control. The systemic circulation accommodated to the changes in muscle perfusion. Our results indicate that, when coping with severe haematological challenges, local regulation of skeletal muscle blood flow and O(2) delivery primarily senses alterations in the oxygenation state of haemoglobin and, to a lesser extent, alterations in the number of RBCs and haemoglobin molecules.

    Objective To explore the associations of white blood cell (WBC) count,alanine aminotransferase (ALT),and aspartate aminotransferase(AST) in the first trimester of pregnancy with gestational diabetes mellitus (GDM). Methods Totally 725 GDM women and 935 women who remained euglycemic throughout pregnancy were enrolled in this study. Pre-pregnancy weight/height were recorded. WBC,ALT,and AST levels were detected between 8 and 12 weeks of pregnancy.At 24 to 28 weeks of pregnancy,the glucose and insulin levels were measured. The WBC,ALT,and AST levels were compared between two groups,and the associations of WBC,ALT,and AST levels with the blood glucose and insulin levels were retrospectively analyzed. Meanwhile,the potential associations of those factors with the occurrence of GDM were analzyed. Results WBC count [9.41(8.15,10.84)?10(9)/L vs. 9.04 (7.64,10.37)?10(9)/L,P=1.0?10(-5)] and ALT levels [18.00(12.00,30.00)U/L vs. 16.00 (11.00,26.00)U/L,P=0.004] in the first trimester of pregnancy were significantly increased in GDM subjects than in normal glucose tolerance(NGT)subjects;however,the AST level showed no significant difference between these two groups [41.00 (26.00,43.00)U/L vs. 41.00 (23.00,43.00)U/L,P=0.588]. Logistic regression analysis illustrated that elevated WBC count was an independent risk factor for GDM after adjustment for age,pre-pregnancy body mass index,blood pressure,and family history of diabetes(OR=1.119,P=0.001). The ROC curve revealed that threshold of WBC count was 7.965?10(9)/L(AUC=0.566,P=1?10(-5)),which had a sensitivity of 79.4% and a specificity of 31.3%. Multivariate linear regression analysis showed that homeostasis model assessment of insulin resistance was positively correlated with WBC count(B=0.051,P=0.022,R(2)=0.083);1-hour blood glucose after oral 50 grams of sugar (B=0.044,P=0.001,R(2)=0.044) and fasting plasma true insulin(B=0.214,P=0.032,R(2)=0.066) were positively correlated with WBC count;1-hour true insulin after 100 grams

    To investigate the relationship between white blood cell count, neutrophils ratio and erythrocyte sedimentation rate and short outcomes among patients with acute ischemic stroke at admission to the hospital. A total of 2675 acute ischemic stroke patients were included in this study. Data on demographic characteristics, life style, history of disease, white blood cell count (WBC), neutrophils ratio (NEUR), erythrocyte sedimentation rate (ESR) and clinical outcomes were collected for all the participants. Poor clinical outcome was defined as neurologic deficiency (NIHSS ≥ 5) at discharge or death during hospitalization. White blood cell count, neutrophils ratio and erythrocyte sedimentation rate were higher in patients with poor outcome than in those without clinical outcome. According to the quartile range, WBC, NEUR and ESR were divided into four levels at admission. After adjustment for multivariate, compared with WBC ≤ 5.6× 10(9)/L, the odds ratio (95% confidence intervals) of poor outcome with ≥ 8.7×10(9)/L was 1.883 (1.306 - 2.716). When compared with NEUR ≤ 0.56, the odds ratio (95% confidence intervals) of poor outcome with 0.57 - 0.64 and with ≥ 0.74 were 1.572 (1.002 - 2.466) and 2.577 (1.698 - 3.910), respectively. When compared with ESR ≤ 4 mm/h, the odds ratio (95% confidence intervals) of poor outcome with ≥ 17 mm/h was 2.426 (1.233 - 4.776). Elevated WBC count and NEUR at admission were significantly and positively associated with poor clinical outcomes among patients with acute ischemic stroke (trend test P acute ischemic stroke (trend test P > 0.05). There appeared associations between WBC, NEUR, ESR and poor outcome among patients with acute ischemic stroke at admission to the hospital. Both elevated WBC count and NEUR showed significantly positive association with poor clinical outcomes among patients with acute ischemic stroke at admission.

    Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies. For stage I - III RCC surgery is the primary treatment. Systemic therapy is used in the patients with disseminated disease (stage IV). Sunitinib malate is commonly used in the patients with clear cell renal cell carcinoma (ccRCC) rated as 'low' or 'intermediate' risk according to the Motzer scale. Treatment with sunitinib malate is associated with myelotoxicity. To assess its clinical significance we conducted a pilot study in a group of 10 patients. We noticed a gradual decrease in the mean haemoglobin level during subsequent treatment cycles. Alternations in the platelet count were of no clinical significance. Episodes of the neutropenia were noticed in the study group. In some patients neutrophil count decreased to the level that put them at risk of the infectious complications.

    False thrombocytopenia may result from platelet aggregation, especially in feline ethylenediamine tetra-acetic acid (EDTA) blood specimens. Citrate, theophylline, adenosine and dipyridamole (CTAD) was added to 46 feline EDTA specimens to test its anti-aggregation action. Platelet aggregation was estimated from blood films and a complete blood count was performed with a Sysmex XT-2000iV analyser. Platelet aggregation score was >2 in 11/46 EDTA tubes and only in one EDTA+CTAD specimen. The platelet count was higher in all CTAD-supplemented tubes except one, medians measured by cytometry being 225.5 × 10(9)/l and 249.0 × 10(9)/l in EDTA and EDTA+CTAD, respectively (P = 0.007). Adding CTAD had statistically and analytically significant but moderate effects on other blood variables, the most intense variations being observed for reticulocytes (about 3% higher in EDTA specimens) and reticulocyte indexes. Addition of CTAD to EDTA when sampling feline blood is a useful option to reduce platelet clumping.

    Background Inflammation is an important underlying mechanism in the pathogenesis of atherosclerosis, and an elevated resting heart rate underlies the process of atherosclerotic plaque formation. We hypothesized an association between resting heart rate and subclinical inflammation. Methods Resting heart rate was recorded at baseline in the KoGES-ARIRANG (Korean Genome and Epidemiology Study on Atherosclerosis Risk of Rural Areas in the Korean General Population) cohort study, and was then divided into quartiles. Subclinical inflammation was measured by white blood cell count and high-sensitivity C-reactive protein. We used progressively adjusted regression models with terms for muscle mass, body fat proportion, and adiponectin in the fully adjusted models. We examined inflammatory markers as both continuous and categorical variables, using the clinical cut point of the highest quartile of white blood cell count (≥7,900/mm3) and ≥3 mg/dL for high-sensitivity C-reactive protein. Results Participants had a mean age of 56.3±8.1 years and a mean resting heart rate of 71.4±10.7 beats/min; 39.1% were men. In a fully adjusted model, an increased resting heart rate was significantly associated with a higher white blood cell count and higher levels of high-sensitivity C-reactive protein in both continuous (P for trend <0.001) and categorical (P for trend <0.001) models. Conclusion An increased resting heart rate is associated with a higher level of subclinical inflammation among healthy Korean people.

    Full Text Available Background & Objective: The regular exercise training is known as a preventive and adjuvant therapy in inflammatory diseases such as cancer. The aim of this study was to determine the effect of the aerobic training on IL-10 and IL-8 levels and the count of white blood cells (WBC in women with breast cancer. Material & Methods: The statistical society of the present study included Kerman women with breast cancer. Forty patients with breast cancer were randomly divided into two groups: exercise (n = 20 and control (n = 20. The exercise group performed the endurance training for 8 weeks with the intensity between 40 to 55 percent of the target heart rate. Twenty four hours before the first session and 48 hours after the last session of the exercise protocol, blood samples were taken from both groups and then IL-10 and IL-8 levels in serum were measured by ELISA via a Boster kit. Results: The results of the present study showed that 8 weeks of the endurance exercise training did not significantly increase the IL-10 (P=0.113 serum level, but increased the WBC count (p=0.019 and decreased the serum level of IL-8 (p=0.03 significantly. Conclusion: According to the results of the present study, regular endurance training via decreasing the inflammatory factors can be considered as an effective factor along with other therapies in improving breast cancer.

    Radioactive131 iodine (RAI) body burden is estimated in thyroid cancer patients by a) exposure rate meter and b) external probe counting. A calibration factor of 301 cpm/MBq (d = 16 cm) is used for the probe for estimates of whole body activity. Patients sit in a rotating stool with their center corresponding to the field of view for estimation of whole body RAI. Radioactive counts are obtained for anterio posterior (AP) and postero anterior (PA) geometries. Whole body retention factor is expressed as a ratio against assayed activity administered to the patient on day 1. With exposure rate measurement, for off-thyroxin (hypothyriod) patients, the retention factors were 0.148 ± 0.12 (n = 211) and 0.07 ± 0.08 (n = 68) at 48 h and 72 h, respectively. For recombinant TSH (rhTSH) (euthyroid) group, the retention factors were 0.089 ± 0.06 (n = 24) and 0.05 ± 0.05 (n = 19) at 48 h and 72 h, respectively. By probe counting method, the obtained retention factors were 0.081 ± 0.013 (range: 0.071–0.096) (off-thyroxine group) and 0.039 ± 0.03 (range: 0.008–0.089) for the rhTSH group at 48 h. The 72 h retentions in the off thyroxine (hypothyriod) group and the rhTSH (euthyroid) group were 0.048 ± 0.024 (range: 0.016–0.076) and 0.005, respectively. The radioactive body burdens at 48 h were in the range of 290-315 MBq (7.8–8.5 mCi) for the off-thyroxine group and 44–286 MBq (1.2–7.7 mCi) for the rhTSH group. The calculated residence times in whole body were 21.97 ± 3.8 h (range: 17.1–27.1) for off-thyroxine group and 14.28 ± 2.75 h (range: 9.97-19.46) showing high statistical significance (P radioactive iodine. There was no correlation between administered activity and retained body burden at 48 h or 72 h. PMID:27651735

    IL-33 is a tissue-derived cytokine that induces and amplifies eosinophilic inflammation and has emerged as a promising new drug target for asthma and allergic disease. Common variants at IL33 and IL1RL1, encoding the IL-33 receptor ST2, associate with eosinophil counts and asthma. Through whole-genome sequencing and imputation into the Icelandic population, we found a rare variant in IL33 (NM_001199640:exon7:c.487-1G>C (rs146597587-C), allele frequency = 0.65%) that disrupts a canonical splice acceptor site before the last coding exon. It is also found at low frequency in European populations. rs146597587-C associates with lower eosinophil counts (β = -0.21 SD, P = 2.5×10–16, N = 103,104), and reduced risk of asthma in Europeans (OR = 0.47; 95%CI: 0.32, 0.70, P = 1.8×10–4, N cases = 6,465, N controls = 302,977). Heterozygotes have about 40% lower total IL33 mRNA expression than non-carriers and allele-specific analysis based on RNA sequencing and phased genotypes shows that only 20% of the total expression is from the mutated chromosome. In half of those transcripts the mutation causes retention of the last intron, predicted to result in a premature stop codon that leads to truncation of 66 amino acids. The truncated IL-33 has normal intracellular localization but neither binds IL-33R/ST2 nor activates ST2-expressing cells. Together these data demonstrate that rs146597587-C is a loss of function mutation and support the hypothesis that IL-33 haploinsufficiency protects against asthma. PMID:28273074

    The aim of the study was to examine the effects of melatonin impact on changes in haematological profile, biomarkers of oxidative stress (dienes conjugates, malondialdehyde (MDA), oxidatively modified protein levels, total antioxidant capacity and antioxidant enzyme activity) in liver, muscle, kidney and erythrocytes, and glycated haemoglobin (HBA1c) in mice during acute ethanol stress. Assays were carried out in quadruplicate: control, melatonin (10 mg/kg, 10 days), acute ethanol stress (0.75 g/kg/day, 10 days) and acute ethanol stress plus melatonin groups. Acute ethanol stress caused a significant increase in the total number of white blood cells (WBC), especially neutrophils in the blood, and HBA1c levels vs. control mice. The correlation between lipid peroxidation and the glycated haemoglobin level was shown (r = 0.93, P = 0.007). Ethanol reduced the antioxidant capacity by increasing reactive oxygen species (ROS) production and the level of oxidatively modified protein content, diene conjugates and MDA. Melatonin administration in animals during acute ethanol stress reduced antioxidant stress biomarkers, WBC, HBA1c levels and ROS production. Melatonin had protective effects on liver, kidney and muscle tissues by preventing the intensive lipid peroxidation processes in initial (diene conjugation production) and late stages (MDA level), and significantly reduced the level of aldehyde and ketone protein derivatives. Furthermore, melatonin restored elevated WBC count and HBA1c level and diminished ROS production. Ethanol reduces antioxidant capacity and leads to exaggerated reactive oxygen species production and consequent increases in oxidatively modified proteins. Melatonin exerts protective effects by preventing the intensive lipid peroxidation processes. Melatonin significantly reduces the level of aldehyde and ketone protein derivatives, restores glycated haemoglobin level and white blood cell count.

    Traditional statistical models often are based on certain presuppositions and limitations that may not presence in actual data and lead to turbulence in estimation or prediction. In these situations, artificial neural networks (ANNs) could be suitable alternative rather than classical statistical methods.  A prospective cohort study. The study was conducted in Shahrekord Blood Transfusion Center, Shahrekord, central Iran, on blood donors from 2008-2009. The accuracy of the proposed model to prediction of number of return to blood donations was compared with classical statistical models. A number of 864 donors who had a first-time successful donation were followed for five years. Number of return for blood donation was considered as response variable. Poisson regression (PR), negative binomial regression (NBR), zero-inflated Poisson regression (ZIPR) and zero-inflated negative binomial regression (ZINBR) as well as ANN model were fitted to data. MSE criterion was used to compare models. To fitting the models, STATISTICA 10 and, R 3.2.2 was used RESULTS: The MSE of PR, NBR, ZIPR, ZINBR and ANN models was obtained 2.71, 1.01, 1.54, 0.094 and 0.056 for the training and 4.05, 9.89, 3.99, 2.53 and 0.27 for the test data, respectively. The ANN model had the least MSE in both training, and test data set and has a better performance than classic models. ANN could be a suitable alternative for modeling such data because of fewer restrictions.

    After surgery, breast cancer patients are offered adjuvant chemotherapy to avoid cancer cell spread. During chemotherapy process, neutrophils could fall relatively, and side effects could spike to the peak. Therefore, the medical care personnel should prevent the progression of the side effects. This study aimed to examine the effects of Chan-Chuang qi-gong therapy on complete blood counts in breast cancer patients treated with chemotherapy. This study used a quasi-experimental design. The experiment group (n = 32) received a 21-day Chan-Chuang qi-gong therapy, whereas the control group (n = 35) did not. White blood cells, platelet, and hemoglobin were measured on the day before chemotherapy and on days 8, 15, and 22 during chemotherapy. According to this study, there were significant differences in white blood cells (F = 115.76, P qi-gong therapy may decrease leukopenia in breast cancer patients treated with chemotherapy. It is recommended conducting more studies on qi-gong and then introducing it in clinical nursing practice at an appropriate time to promote quality of nursing care and quality of patient life.

    EGID is a known post-transplant complication. Its etiology has been related to antirejection medication, but other factors may also play a role as only few transplant recipients develop EGID despite standardized treatment. This study aimed to determine whether EGID is associated with rejection events and with a specific phenotype of the rejection-positive graft biopsies in children with solid organ transplant. All patients with liver, heart, and kidney transplant followed at our institution were included in the study. Digestive tract eosinophilia was more common in heart and liver recipients and was a rare event after renal transplantation. Subjects with EGID had higher incidence of rejection and elevated peripheral blood AEC. The first rejection event and high AEC values preceded EGID diagnosis in the majority of patients. Histologically, the initial rejection-positive graft biopsy revealed accentuated eosinophilia in EGID patients compared with non-EGID cohort, which correlated with higher blood eosinophil counts at the time of first rejection episode. Prominent graft tissue and peripheral blood eosinophilia prior to EGID diagnosis suggests a predisposition for eosinophil activation in patients with post-transplant digestive eosinophilic disorder. These parameters can be used as markers for subsequent development of EGID. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Bronchial asthma is a worldwide disease with high incidence. It not only harms children's physical and mental health, but it also brings a heavy burden to their families as well as the society. However, the trigger and pathogenesis of the disease remain unclear. This study aimed to analyze TRPV1 gene mutation and expression of cytokines in children with acute bronchial asthma before and after treatment, thus providing theoretical guidance for the diagnosis and treatment of bronchial asthma in children. Real-time quantitative polymerase chain reaction was adopted to detect TRPV1 mRNA expression level and enzyme-linked immuno sorbent assay was used to detect the serum total IgE level, eosinophil (EOS) number, IL-4, IL-5, and interferon (IFN) gamma levels in peripheral venous blood of children in the healthy control group and asthma group before and after treatment. Logistic regression analysis was applied to analyze the most essential factor inducing bronchial asthma in children. TRPV1 mRNA level of peripheral blood in the asthma group was higher than that in the control group before treatment (p asthma in children. TRPV1 gene mutation was closely related to bronchial asthma in children, which provided a theoretical basis for the treatment and prognosis of children with bronchial asthma.

    In lung sound analysis, the narrower the airways are, the higher the frequency of breathing sounds is, and, if a patient has higher than normal breathing sounds, i.e., bronchial sounds, he or she may have airway narrowing or airway inflammation. It is sometimes difficult to detect subtle changes in lung sounds; therefore, we anticipate that automated analysis of lung sounds will be used to overcome these difficulties in the near future.

    Full Text Available Abstract Background Nosocomial bacteremia is associated with a poor prognosis. Early adequate therapy has been shown to improve outcome. Consequently, rapid detection of a beginning sepsis is therefore of the utmost importance. This historical cohort study was designed to evaluate if different patterns can be observed in either C-reactive protein (CRP and white blood cell count (WCC between Gram positive bacteremia (GPB vs. Gram negative bacteremia (GNB, and to assess the potential benefit of serial measurements of both biomarkers in terms of early antimicrobial therapy initiation. Methods A historical study (2003–2004 was conducted, including all adult intensive care unit patients with a nosocomial bacteremia. CRP and WCC count measurements were recorded daily from two days prior (d-2 until one day after onset of bacteremia (d+1. Delta (Δ CRP and Δ WCC levels from the level at d-2 onward were calculated. Results CRP levels and WCC counts were substantially higher in patients with GNB. Logistic regression analysis demonstrated that GNB and Acute Physiology and Chronic Health Evaluation (APACHE II score were independently associated with a CRP increase of 5 mg/dL from d-2 to d+1, and both were also independently associated with an increase of WCC levels from d-2 to d+1 of 5,000 × 103 cells/mm3. Conclusion Increased levels of CRP and WCC are suggestive for GNB, while almost unchanged CRP and WCC levels are observed in patients with GPB. However, despite the different patterns observed, antimicrobial treatment as such cannot be guided based on both biomarkers.

    To focus on both positive and negative aspects of the interaction between asthmatic patients and the social networks, and to highlight the need of a psychological approach in some individuals to integrate pharmacological treatment is the purpose of review. There is evidence that in some asthmatic patients, the excessive use of social networks can induce depression and stress triggering bronchial obstruction, whereas in others their rational use can induce beneficial effects in terms of asthma management. The increasing asthma prevalence in developed countries seen at the end of last century has raised concern for the considerable burden of this disease on society as well as individuals. Bronchial asthma is a disease in which psychological implications play a role in increasing or in reducing the severity of bronchial obstruction. Internet and, in particular, social media are increasingly a part of daily life of both young and adult people, thus allowing virtual relationships with peers sharing similar interests and goals. Although social network users often disclose more about themselves online than they do in person, there might be a risk for adolescents and for sensitive individuals, who can be negatively influenced by an incorrect use. However, although some studies show an increased risk of depression, other observations suggest beneficial effects of social networks by enhancing communication, social connection and self-esteem.

    Full Text Available This study was conducted to determine the effect of using plant essential oils in triticale-based broiler diets as alternative to antimicrobial growth promotors (AGPs on growth, E.coli counts in small intestine and blood parameters. 720 male broiler chicks were randomly distributed to nine experimental groups with four replicates. The control group received the triticale-soybean meal basal diet. In the other treatment groups the basal diet was supplemented with one of the following; flavomycin, enzyme, flavomycin+enzyme, enzyme+thyme oil, enzyme+fennel oil, enzyme+bay leaf oil, enzyme+thyme oil+fennel oil and enzyme+thyme oil+fennel oil+bay leaf oil. Results showed that the weight gain and feed intake were not influenced by the treatments (P>0,05. The use of the combination of plant extracts significantly improved the feed conversion. Use of plant extracts in triticale-based broiler diets as an alternative to AGPs had no regular effect on E.coli count in small intestine segments (P>0,05. Feeding broiler chickens with the enzyme+thyme oil supplemented diets increased eritrocyte level in serum (P0,05 by the treatments. In conclusion, these plant ectracts can be also used with enzyme in triticale-based broiler diets as alternative to AGPs.

    Thirty-nine samples of synovial fluid were collected from the joints of 32 horses with suspected septic arthritis and 39 samples were collected from horses euthanased for non-orthopaedic conditions. The white blood cell counts (WBCC) were determined and the pro and active forms of matrix metalloproteinases (MMPs) 2 and 9 were measured by gelatin zymography and image analysis in each sample. The initial measurements of the ratio of proMMP9:proMMp2 and WBCC were good prognostic indicators of the survival of the horses. There was no significant relationship between the interval between the injury and the horse being referred for treatment and either the WBCC or the levels of MMP2 and MMP9 initially, and no evidence that this interval significantly affected the chances of the horses surviving.

    Failure in mobilization of peripheral blood (PB) stem cells is a frequent reason for not performing hematopoietic stem cell transplantation (HSCT). Early identification of poor mobilizers could avoid repeated attempts at mobilization, with the administration of pre-emptive rescue mobilization. Data from the first mobilization schedule of 397 patients referred consecutively for autologous HSCT between 2000 and 2010 were collected. Poor mobilization was defined as the collection of 13.8/μL was enough to ensure ≥ 2 × 10(6) CD34(+)cells/kg, with high sensitivity (90%) and specificity (91%). The prevalence of poor mobilization was high, being associated with disease type, therapy with purine analogs and multiple chemotherapy regimens. The threshold of CD34(+) cell count in PB identified poor mobilizers, in whom the administration of immediate or pre-emptive plerixafor could be useful to avoid a second mobilization.

    This study was undertaken to determine whether concentrations of procalcitonin in the blood of neonates with nosocomial infections depend on the type of pathogen. Qualification for the study group was based on the clinical signs of infection. We found that infections with Gram-positive (chiefly coagulase-negative staphylococci) and Gram-negative bacteria are accompanied by elevated concentrations of procalcitonin. In the case of Gram-positive bacteria, other laboratory signs of infection studied by us (concentration of C-reactive protein, white blood cell count, immature-to-total neutrophil ratio) were not discriminatory, confirming the diagnostic usefulness of procalcitonin measurements in nosocomial infections of the neonate with Gram-negative or Gram-positive bacteria.

    Background and Aims: We sought to evaluate the prognosis of preoperative blood routine parameters for the mortality of colorectal cancer patients after surgery by eliciting a subset of data from the ongoing Fujian prospective investigation of cancer (FIESTA) study. Methods: 1318 colorectal cancer patients with completed survival data were enrolled between 2000 and 2008. Effect-size estimates are expressed as hazard ratio (HR) and 95% confidence interval (CI). Results: The median follow-up time was 58.6 months. Elevated levels of neutrophil (adjusted HR, 95% CI, P: 1.22, 1.06-1.41, 0.006) and monocyte (1.32, 1.06-1.65, 0.013) were significantly associated with an increased risk of colorectal cancer mortality, whereas that of lymphocyte (0.60, 0.44-0.82, 0.001) and red blood cell count (0.20, 0.09-0.43, <0.001) were significantly associated with a reduced risk. Additionally, remarkable significance was reached for the neutrophil-to-lymphocyte ratio (1.12, 1.06-1.19, <0.001) and lymphocyte-to-monocyte ratio (0.60, 0.46-0.79, <0.001). Based on individual effect-estimates, a new derivate, monocyte to red blood cell count ratio namely MRR was created, and its association with colorectal cancer mortality was strikingly significant (1.48, 1.18-1.85, 0.001). Notably, elevated MRR was significantly associated with the mortality of early stage colorectal cancer, especially in patients with stage I-II (1.63, 1.04-2.56, 0.034), invasion depth T1-T2 (2.85, 1.45-5.61, 0.002), regional lymph node metastasis N0 (1.89, 1.29-2.77, 0.001) and tumor size ≤ 4.5 cm (1.84, 1.25-2.70, 0.002). Conclusions: We created a new derivate MRR, which was superior over classic blood routine derivates, and importantly the MRR exhibited a stronger ability in predicting poor prognosis of colorectal cancer, especially at the early stage.

    Full Text Available miR-155 has been confirmed to be a key factor in immune responses in humans and other mammals. Therefore, investigation of variations in miR-155 could be useful for understanding the differences in immunity between individuals. In this study, four SNPs in miR-155 were identified in mice (Mus musculus and humans (Homo sapiens. In mice, the four SNPs were closely linked and formed two miR-155 haplotypes (A and B. Ten distinct types of blood parameters were associated with miR-155 expression under normal conditions. Additionally, 4 and 14 blood parameters were significantly different between these two genotypes under normal and lipopolysaccharide (LPS stimulation conditions, respectively. Moreover, the expression levels of miR-155, the inflammatory response to LPS stimulation and the lethal ratio following Salmonella typhimurium infection were significantly increased in mice harboring the AA genotype. Further, two SNPs, one in the loop region and the other near the 3' terminal of pre-miR-155, were confirmed to be responsible for the differential expression of miR-155 in mice. Interestingly, two additional SNPs, one in the loop region and the other in the middle of miR-155*, modulated the function of miR-155 in humans. Predictions of secondary RNA structure using RNAfold showed that these SNPs affected the structure of miR-155 in both mice and humans. Our results provide novel evidence of the natural functional SNPs of miR-155 in both mice and humans, which may affect the expression levels of mature miR-155 by modulating its secondary structure. The SNPs of human miR-155 may be considered as causal mutations for some immune-related diseases in the clinic. The two genotypes of mice could be used as natural models for studying the mechanisms of immune diseases caused by abnormal expression of miR-155 in humans.

    Full Text Available Total white blood cell (WBC and neutrophil counts are lower among individuals of African descent due to the common African-derived "null" variant of the Duffy Antigen Receptor for Chemokines (DARC gene. Additional common genetic polymorphisms were recently associated with total WBC and WBC sub-type levels in European and Japanese populations. No additional loci that account for WBC variability have been identified in African Americans. In order to address this, we performed a large genome-wide association study (GWAS of total WBC and cell subtype counts in 16,388 African-American participants from 7 population-based cohorts available in the Continental Origins and Genetic Epidemiology Network. In addition to the DARC locus on chromosome 1q23, we identified two other regions (chromosomes 4q13 and 16q22 associated with WBC in African Americans (P<2.5×10(-8. The lead SNP (rs9131 on chromosome 4q13 is located in the CXCL2 gene, which encodes a chemotactic cytokine for polymorphonuclear leukocytes. Independent evidence of the novel CXCL2 association with WBC was present in 3,551 Hispanic Americans, 14,767 Japanese, and 19,509 European Americans. The index SNP (rs12149261 on chromosome 16q22 associated with WBC count is located in a large inter-chromosomal segmental duplication encompassing part of the hydrocephalus inducing homolog (HYDIN gene. We demonstrate that the chromosome 16q22 association finding is most likely due to a genotyping artifact as a consequence of sequence similarity between duplicated regions on chromosomes 16q22 and 1q21. Among the WBC loci recently identified in European or Japanese populations, replication was observed in our African-American meta-analysis for rs445 of CDK6 on chromosome 7q21 and rs4065321 of PSMD3-CSF3 region on chromosome 17q21. In summary, the CXCL2, CDK6, and PSMD3-CSF3 regions are associated with WBC count in African American and other populations. We also demonstrate that large inter

    Interest in childhood metabolic syndrome (MetS) has increased substantially due to the increasing prevalence of childhood obesity on a global scale. Early recognition of MetS is critical in order to delay the development of cardiovascular disease (CVD). In this study, we evaluated the relationship between complete blood count (CBC) parameters and MetS among pre-pubertal children which may provide evidence in support of using low cost, readily available clinical haematological parameters for the detection of MetS. A retrospective analysis was carried out on 330 (125 lean vs. 205 overweight) Turkish pre-pubertal children who attend to a paediatric outpatient clinic. Age, gender, puberty, body mass index, CBC parameters, cardiometabolic risk factors including lipid profiles, high sensitive serum reactive protein (hsCRP) and insulin resistance index calculated by homeostasis model assessment (HOMA-IR) were evaluated and compared among lean, overweight children and children with MetS. The mean age of the study population was 7.4 ± 1.9 years. In both gender, the mean values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were significantly lower and red blood cell (RBC), platelet (PLT) counts were significantly higher in overweight children. Overall, 8.4% (n = 28) of patients met the criteria of MetS. Children with MetS had higher levels of PLT and lower levels of mean platelet volume (MPV). Of all the haematological parameters analysed, PLT was positively, whereas MPV was negatively correlated with MetS in girls. In addition, MPV was inversely correlated with fasting blood glucose, HOMA-IR, low density lipoprotein-cholesterol (LDL-C) and low density lipoprotein-cholesterol/high density lipoprotein-cholesterol (LDL-C/HDL-C) ratio in girls after adjusting for confounding factors. The risk analyses of MetS in terms of MPV quartiles showed that the adjusted OR (95% CI) for the lowest vs. the

    The analysis of the prescriptions for bronchial asthma (BA) patients in outpatient practice was made using data base created at the Regional Fund of Obligatory Health Insurance in the Sverdlovsk region with consideration of GINA principles of BA stepped care. The real structure of prescriptions was compared with the pattern drug official list for asthma care. The cost of each BA care step was calculated on the base of the computer programs. The analysis showed low quality of BA care in outpatient practice. The created computer programs are very useful for the prescriptions structure monitoring, cost-effect analysis and pharmacotherapeutical management of the diseases.

    Epidural emphysema is an exceptional complication of bronchial asthma, revealed by an incidental finding in chest tomography. We report a case of a 21-year-old man admitted with asthma attack complicated by subcutaneous and mediastinal emphysema. Chest tomography confirmed the mediastinal emphysema and also revealed the epidural emphysema within the vertebral canal. Neurological examination was negative. The patient showed complete recovery 10days after the onset of symptoms. The epidural emphysema is a rare complication during asthma attacks. The benignity of this complication should not require a systematic chest tomography.

    BACKGROUND:Course of diabetes and hypertension are independent risk factors for diabetic microvascular complications, and fasting C-peptide level is a protective factor. There are many studies concerning glycated hemoglobin, C-reactive protein, white blood cel count and diabetic microvascular complications, but studies about neutrophils are rarely reported. OBJECTIVE:To investigate the relationship of peripheral blood neutrophil count with diabetic microvascular complications. METHODS:Totaly 112 patients with type 2 diabetes melitus were selected and divided into two groups according to the presence or absence of microvascular complications: diabetes group and diabetes+ microvascular complication group. The gender, age, ethnic group, disease history and laboratory examination parameters were colected and analyzed with univariate analysis and multivariate analysis. RESULTS AND CONCLUSION:(1) Univariate analysis: Patients in the diabetes+microvascular complication group had significantly higher age, course of diabetes, globulin, creatinine, the percentage of neutrophile granulocytes, nertrophil count, rate of hypertension than those in the diabetes group (P < 0.05), while the lymphocyte percentage, glomerular filtration rate, and triglyceride level were significantly lower than those in the diabetes group (P < 0.05). (2) Logistic regression analysis showed that age, course of diabetes and nertrophil count were the independent risk factors of microvascular complications in patients with type 2 diabetes melitus (odds ratio=1.155, 2.145, 2.275, alP < 0.01). Based on the adjustment of the age factor, the partial correlation analysis showed that the nertrophil count was positively correlated to the levels of creatinine, low-density lipoprotein cholesterol, globulin and hemoglobin, but negatively correlated to the levels of serum bile acid and glomerular filtration rate. Chronic subclinical inflammations are closely correlated to the occurrence of microvascular

    Full Text Available Forty-two patients with allergic bronchial asthma (ABA forty persons with non-allergic bronchial asthma (NABA, and 47 healthy controls were involved into the study. Expression of FoxP3 mRNA was analyzed by RT-PCR. In patients with bronchial asthma (ABA and NABA we have revealed a significant decrease in FoxP3 mRNA expression levels, in comparison with control group. The patients with severe BA exhibited lowest levels of the FoxP3 mRNA expression as compared with other groups.We revealed a decreased FoxP3 mRNA expression in mononuclear cells from peripheral blood, and an increased IL-17 level in blood serum of patients with bronchial asthma. These results may be considered a manifestation of serious inflammatory process. Probably, the data may reflect a disregulated expression of FoxP3 transcription factor. Therefore, we may assume a key role of FoxP3 for regulation of inflammatory activity in bronchial asthma.

    1. Needle acupuncture was performed at three sites in twenty patients in a clinical attack of bronchial asthma. 2. In all patients the symptoms of bronchoconstriction improved during the attacks when the correct site was stimulated, and in five patients wheezing was abolished. 3. Stimulation at the correct site produced a significant increase in the mean FEV1-0 (58%) and FVC (29%) but not in maximal mid-expiratory flow rate (MMFR; 76%), when compared with the findings before acupuncture, along with a significant fall in the Pa,CO2 and an insignificant fall in Pa,O2. A mild tachycardia was also observed. 4. After acupuncture a greater improvement in FEV1-0, FVC and MMFR was produced by inhalation of isoprenaline. 5. No significant changes in FEV1-0, FVC, MMFR, pulse rate or arterial blood gas tensions occurred after acupuncture at control sites. 6. In four of the patients during clinical remission acupuncture was performed before and after histamine aerosol challenge, but there was no effect on either the severity or the duration of the histamine-induced bronchoconstriction. 7. It is concluded that acupunture probably reduced the reflex component of the bronchoconstriction, but failed to influence direct smooth muscle constriction caused by histamine.

    Full Text Available OBJECTIVE: Biological evidence suggests that inflammation might induce type 2 diabetes (T2D, and epidemiological studies have shown an association between higher white blood cell count (WBC and T2D. However, the association has not been systematically investigated. RESEARCH DESIGN AND METHODS: Studies were identified through computer-based and manual searches. Previously unreported studies were sought through correspondence. 20 studies were identified (8,647 T2D cases and 85,040 non-cases. Estimates of the association of WBC with T2D were combined using random effects meta-analysis; sources of heterogeneity as well as presence of publication bias were explored. RESULTS: The combined relative risk (RR comparing the top to bottom tertile of the WBC count was 1.61 (95% CI: 1.45; 1.79, p = 1.5*10(-18. Substantial heterogeneity was present (I(2 = 83%. For granulocytes the RR was 1.38 (95% CI: 1.17; 1.64, p = 1.5*10(-4, for lymphocytes 1.26 (95% CI: 1.02; 1.56, p = 0.029, and for monocytes 0.93 (95% CI: 0.68; 1.28, p = 0.67 comparing top to bottom tertile. In cross-sectional studies, RR was 1.74 (95% CI: 1.49; 2.02, p = 7.7*10(-13, while in cohort studies it was 1.48 (95% CI: 1.22; 1.79, p = 7.7*10(-5. We assessed the impact of confounding in EPIC-Norfolk study and found that the age and sex adjusted HR of 2.19 (95% CI: 1.74; 2.75 was attenuated to 1.82 (95% CI: 1.45; 2.29 after further accounting for smoking, T2D family history, physical activity, education, BMI and waist circumference. CONCLUSIONS: A raised WBC is associated with higher risk of T2D. The presence of publication bias and failure to control for all potential confounders in all studies means the observed association is likely an overestimate.

    Fatal asthma is characterised by enlargement of bronchial mucous glands and tenacious plugs of mucus in the airway lumen. Myoepithelial cells, located within the mucous glands, contain contractile proteins which provide structural support to mucous cells and actively facilitate glandular secretion. To determine if myoepithelial cells are increased in the bronchial submucosal glands of patients with fatal asthma. Autopsied lungs from 12 patients with fatal asthma (FA), 12 patients with asthma dying of non-respiratory causes (NFA) and 12 non-asthma control cases (NAC) were obtained through the Prairie Provinces Asthma Study. Transverse sections of segmental bronchi from three lobes were stained for mucus and smooth muscle actin and the area fractions of mucous plugs, mucous glands and myoepithelial cells determined by point counting. The fine structure of the myoepithelial cells was examined by electron microscopy. FA was characterised by significant increases in mucous gland (p = 0.003), mucous plug (p = 0.004) and myoepithelial cell areas (p = 0.017) compared with NAC. When the ratio of myoepithelial cell area to total gland area was examined, there was a disproportionate and significant increase in FA compared with NAC (p = 0.014). Electron microscopy of FA cases revealed hypertrophy of the myoepithelial cells with increased intracellular myofilaments. The NFA group showed changes in these features that were intermediate between the FA and NAC groups but the differences were not significant. Bronchial mucous glands and mucous gland myoepithelial cell smooth muscle actin are increased in fatal asthma and may contribute to asphyxia due to mucous plugging.

    The automated laser-based hematology analyzer Sysmex XT-2000iV™ providing a complete blood cell count (CBC) and 5-part differential has been introduced in large veterinary laboratories. The aim of the current study was to determine precision, linearity, and accuracy of the Sysmex analyzer. Reference method for the accuracy study was the laser-based hematology analyzer ADVIA® 2120. For evaluation of accuracy, consecutive fresh blood samples from healthy and diseased cats (n = 216), dogs (n = 314), and horses (n = 174) were included. A low intra-assay coefficient of variation (CV) of approximately 1% was seen for the CBC except platelet count (PLT). An intra-assay CV ranging between 2% and 5.5% was evident for the differential count except for feline and equine monocytes (7.7%) and horse eosinophils (15.7%). Linearity was excellent for white blood cell count (WBC), hematocrit value, red blood cell count (RBC), and PLT. For all evaluated species, agreement was excellent for WBC and RBC, with Spearman rank correlation coefficients (r(s)) ranging from >0.99 to 0.98. Hematocrit value correlated excellently in cats and dogs, whereas for horses, a good correlation was evident. A good correlation between both analyzers was seen in feline and equine PLT (r(s) = 0.89 and 0.92, respectively), whereas correlation was excellent for dogs (r(s) = 0.93). Biases were close to 0 except for mean corpuscular hemoglobin concentration (4.11 to -7.25 mmol/l) and canine PLT (57 × 10(9)/l). Overall, the performance of the Sysmex analyzer was excellent and compared favorably with the ADVIA analyzer.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

    Molecular and cellular markers associated with malignant disease are frequently identified in healthy individuals. The relationship between these markers and clinical disease is not clear, except where a neoplastic cell population can be identified as in myeloma/monoclonal gammopathies of undetermined significance (MGUS). We have used the distinctive phenotype of chronic lymphocytic leukemia (CLL) cells to determine whether low levels of these cells can be identified in individuals with normal complete blood counts. CLL cells were identified by 4-color flow cytometric analysis of CD19/CD5/CD79b/CD20 expression in 910 outpatients over 40 years old. These outpatients were age- and sex-matched to the general population with normal hematologic parameters and no evident history of malignant disease. CLL phenotype cells were detectable in 3.5% of individuals at low level (median, 0.013; range, 0.002- 1.458 x 10(9) cells/L), and represented a minority of B lymphocytes (median, 11%; range, 3%-95%). Monoclonality was demonstrated by immunoglobulin light-chain restriction in all cases with CLL phenotype cells present and confirmed in a subset of cases by consensus-primer IgH-polymerase chain reaction. As in clinical disease, CLL phenotype cells were detected with a higher frequency in men (male-to-female ratio, 1.9:1) and elderly individuals (2.1% of 40- to 59-year-olds versus 5.0% of 60- to 89-year-olds, P =.01). The neoplastic cells were identical to good-prognosis CLL, being CD5+23+20(wk)79b(wk)11a(-)22(wk)sIg(wk)CD38-, and where assessed had a high degree (4.8%-6.6%) of IgH somatic hypermutation. The monoclonal CLL phenotype cells present in otherwise healthy individuals may represent a very early stage of indolent CLL and should be useful in elucidating the mechanisms of leukemogenesis.

    The aim of this study was to compare the effect of an intermittent intense aerobic exercise session and a resistance exercise session on blood cell counts and oxidative stress parameters in middle-aged women. Thirty-four women were selected and divided into three groups: RE group (performing 60 min of resistance exercises, N = 12), spinning group (performing 60 min of spinning, N = 12), and control group (not exercising regularly, N = 10). In both exercise groups, lymphocytes and monocytes decreased after 1-h recuperation (post-exercise) compared to immediately after exercise (P < 0.05). Immediately after exercise, in both exercised groups, a significant increase in TBARS (from 16.5 ± 2 to 25 ± 2 for the spinning group and from 18.6 ± 1 to 28.2 ± 3 nmol MDA/mL serum for the RE group) and protein carbonyl (from 1.0 ± 0.3 to 1.6 ± 0.2 for the spinning group and from 0.9 ± 0.2 to 1.5 ± 0.2 nmol/mg protein for the RE group) was observed (P < 0.05). A decrease in antioxidant activities (non-protein sulfhydryl, superoxide dismutase, catalase) was also demonstrated with a negative correlation between damage markers and antioxidant body defenses (P < 0.05). These results indicate that an acute bout of intermittent or anaerobic exercise induces immune suppression and increases the production of reactive oxygen species, causing oxidative stress in middle-aged and trained women. Furthermore, we demonstrated that trained women show improved antioxidant capacity and lower oxidative damage than sedentary ones, demonstrating the benefits of chronic regular physical activity.

    Full Text Available Dengue often presents with non-specific clinical signs, and given the current paucity of accurate, rapid diagnostic laboratory tests, identifying easily obtainable bedside markers of dengue remains a priority. Previous studies in febrile Asian children have suggested that the combination of a positive tourniquet test (TT and leucopenia can distinguish dengue from other febrile illnesses, but little data exists on the usefulness of these tests in adults or in the Americas. We evaluated the diagnostic accuracy of the TT and leucopenia (white blood cell count <5000/mm(3 in identifying dengue as part of an acute febrile illness (AFI surveillance study conducted in the Emergency Department of Saint Luke's Hospital in Ponce, Puerto Rico. From September to December 2009, 284 patients presenting to the ED with fever for 2-7 days and no identified source were enrolled. Participants were tested for influenza, dengue, leptospirosis and enteroviruses. Thirty-three (12% patients were confirmed as having dengue; 2 had dengue co-infection with influenza and leptospirosis, respectively. An infectious etiology was determined for 141 others (136 influenza, 3 enterovirus, 2 urinary tract infections, and 110 patients had no infectious etiology identified. Fifty-two percent of laboratory-positive dengue cases had a positive TT versus 18% of patients without dengue (P<0.001, 87% of dengue cases compared to 28% of non-dengue cases had leucopenia (P<0.001. The presence of either a positive TT or leucopenia correctly identified 94% of dengue patients. The specificity and positive predictive values of these tests was significantly higher in the subset of patients without pandemic influenza A H1N1, suggesting improved discriminatory performance of these tests in the absence of concurrent dengue and influenza outbreaks. However, even during simultaneous AFI outbreaks, the absence of leucopenia combined with a negative tourniquet test may be useful to rule out dengue.

    Current National Comprehensive Cancer Network guidelines for breast cancer staging include pre-treatment complete blood count (CBC) and liver function tests (LFT) to screen for occult metastatic disease. To date, the relevance of these tests in detecting metastatic disease in asymptomatic women with early-stage breast cancer (Stage I/II) has not been demonstrated. Although chest x-rays are no longer recommended in the NCCN guidelines, many centers continue to include this imaging as part of their screening process. We aim to determine the clinical and financial impact of these labs and x-rays in the evaluation of early-stage breast cancer patients. A single institution IRB-approved retrospective chart review was conducted of patients with biopsy-proven invasive breast cancer treated from January 1, 2005–December 31, 2009. We collected patient demographics, clinical and pathologic staging, chest x-ray, CBC, and LFT results at the time of referral. Patients were stratified according to radiographic stage at the time of diagnosis. We obtained Medicare reimbursement fees for cost analysis. From 2005 to 2009, 1609 patients with biopsy-proven invasive breast cancer were treated at our institution. Of the 1082 patients with radiographic stage I/II disease, 27.3 % of patients had abnormal CBCs. No additional testing was performed to evaluate these abnormalities. In the early-stage population, 24.7 % of patients had elevated LFTs, resulting in 84 additional imaging studies. No metastatic disease was detected. The cost of CBC, LFTs and chest x-rays was $110.20 per patient, totaling $106,410.99. Additional tests prompted by abnormal results cost $58,143.30 over the five-year period. We found that pre-treatment CBCs, LFTs, and chest x-rays did not improve detection of occult metastatic disease but resulted in additional financial costs. Avoiding routine ordering of these tests would save the US healthcare system $25.7 million annually.

    Background A few recent studies have reported that inflammation is associated with the prognosis of acute aortic dissection (AD).There is,however,no systemic investigation regarding the role of plasma C-reactive protein (CRP) and white blood cell (WBC) levels in predicting in-hospital clinical events of acute type AAD.Methods The levels of high-sensitivity CRP and WBC counts were systemically determined after admission in 36 patients with acute type A AD.The variations of plasma CRP and WBC levels in different time windows (admission,1,2,3,4,6,8 days) in patients with acute type A AD were analyzed between patients with events and without events.Results During hospitalization,five patients died,and increased levels of CRP and WBC were found in patients died with acute type A AD compared with patients survived (P <0.01,respectively).Medical treatment may significantly decrease inflammatory response in survived patients with acute type A AD.Additionally,patients with complication of pleural effusion showed higher CRP and WBC levels (P=0.046,P=0.018,respectively).Lower WBC levels were found in survived patients treated medically (P=0.001).Moreover,mean CRP and WBC levels had positive correlations with aortic diameter (r=0.364,P=0.000;r=0.333,P=0.000,respectively) and age (r=0.270,P=0.000,respectively),while negative correlations with the time from onset of symptoms to hospital admission (r=-0.229,P=0.000,r=-0.200,P=0.002,respectively).Univariate analysis showed that age ≥65 years,CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48mm,pleural effusion and diastolic blood pressure ≥105 mmHg were associated with hospital mortality.While CRP ≥12.05 mg/L,WBC ≥12.16×109/L,aortic diameter ≥48 mm were strongly associated with hospital mortality in multiple Logistic regression analysis.Conclusions The results suggested that CRP and WBC were preferred markers for predicting the clinical events in patients with acute type A AD,especially death during

    A knowledge of the limitations of automated platelet counting is essential for the effective care of thrombocytopenic patients and management of platelet stocks for transfusion. For this study, 29 external quality assessment specimen pools with platelet counts between 5 and 64 × 10(9)/L were distributed to more than 1,100 users of 23 different hematology analyzer models. The same specimen pools were analyzed by the international reference method (IRM) for platelet counting at 3 reference centers. The IRM values were on average lower than the all-methods median values returned by the automated analyzers. The majority (~67%) of the automated analyzer results overestimated the platelet count compared with the IRM, with significant differences in 16.5% of cases. Performance differed between analyzer models. The observed differences may depend in part on the nature of the survey material and analyzer technology, but the findings have implications for the interpretation of platelet counts at levels of clinical decision making.

  8. Correlation between Bronchovascular and Cardiovascular Disorders in Children with Bronchial Asthma: Multifacetedness and Inexhaustibility of Problem Study

    T.Ye. Shumna

    2014-12-01

    Full Text Available Due to tight functional interrelation between respiratory apparatus and blood circulation, exacerbation of bronchial asthma in children is associated with changes of cardiovascular system. Multifacetedness of this problem determines comprehensive approach to examination of children with bronchial asthma, involving most available methods of heart function evaluation: echocardiographic heart study with Doppler sonography and electrocardiography. Of great importance is investigation of systemic and pulmonary hemodynamics and microcirculation in bronchial asthma depending on its clinical course. It was found that children with exacerbation of bronchial asthma were detected with pulmonary hypertension, which had gradual regression after attack alleviation. During the remission stage, hemodynamics disturbances in lesser circulation were present in long-lasting and severe course of disease. However, the increase in the pulmonary blood flow parameters in patients only in the early period after attack can be regarded as a compensatory response from the lesser circulation to the decline in respiratory function indices. Therefore, despite the great achievements of science in the study of pathophysiological mechanisms and clinical features of bronchial asthma at different ages, it is necessary to continue further study of all aspects of bronchial asthma in children, because it is not as well studied as asthma in adults.

    Lipopolysaccharides (LPS, the major part of endotoxins) are bacterial proinflammatory substances which can induce in asthmatic patients after inhalation a bronchial obstruction with an increase in both histamine bronchial hyperresponsiveness and blood inflammatory markers. The aim of the present study was to evaluate whether an acute inhalation of sodium cromoglycate, an anti-inflammatory and membrane-stabilizating agent, can block the LPS-induced lung function response. Using a double-blind placebo-controlled crossover method, 7 asthmatic subjects were submitted, at 4 days' interval, to a bronchial challenge test with either solvent solution or LPS (20 micrograms) preceded by inhalation of sodium cromoglycate (10 mg) or placebo. Compared to the solvent reaction, LPS induced a significant bronchial obstruction [measured by both the forced expiratory volume in 1 s (FEV1) and the airway resistances] beginning at the 60th minute and lasting more than 300 min (p sodium cromoglycate significantly inhibited the LPS-induced bronchial obstruction. The total lung capacity did not change significantly after LPS inhalation. Thus, this study showed that in asthmatics the LPS-induced FEV1 response is blocked by acute treatment with sodium cromoglycate. Sodium cromoglycate could be an active treatment in asthmatics exposed to house dust containing endotoxin.

    Full Text Available Background. Bronchial asthma is a common disease caused by interplay between multiple determinants, including genetic and immune variations. Objective. To investigate the main indices of humoral and cellular branches of immunity, features of cytokine regulation and cytokine genes in children with atopic bronchial asthma (BA with different levels of disease control. Design. Fifty children with controlled BA (CBA and 50 with uncontrolled BA (UBA were analyzed. Mean age in the sample was 13.36±2.24 years. A control group of healthy children (n=50 was also studied. All individuals were Russians (Eastern Slavs from the Krasnoyarsk Territory, West Siberia. Diagnoses, severity and level of disease control were defined according to the Global Initiative for Asthma (GINA recommendations. The lymphocytes were counted in blood using fluorescent microscopy. Humoral branch indices and cytokine levels (IL-2, IL-4, IL-10 and TNF-α in blood serum were measured by ELISA. Genotyping of single-nucleotide polymorphism (SNP in −590 position of the IL4 and −597 position of the IL10 gene was performed by restriction fragment length analysis. Results. No statistically significant differences in total IgE and cytokines blood levels were found in CBA and UBA. However, significant differences between the groups were found for CD3+, CD4+, and CD8+, cell counts. The T-590 allele of the IL4 gene, which is responsible for an increased serum level of IL-4, showed a tendency to an association with UBA. A decreased level of IL-10 enhances control over BA, which proves its association with the allelic variant A-597 IL10. Conclusions. Our data show that children with UBA have higher counts of CD3+, cells and an increase of sub-population of CD4+, -cells as well as higher levels of IgE, IL-4 and TNF-α in blood serum as compared to CBA. Polymorphisms of the IL4 and IL10 genes are associated with allergic inflammation in UBA.

    Objective To investigate the changes of fetal nucleated red blood cells count (FNRBC) in peripheral blood of pregnant women with different pregnancy complications, such as hypertensive disorders in pregnancy, gestational diabetes mellitus (GDM) and pregnancy with thrombocytopenia. Methods Thirty clinically diagnosed hypertensive disorders in pregnancy patients (12 cases mild preeclampsia, 12 cases severe preeclampsia,6 cases eclampsia),23 cases GDM patients (13 cases blood sugar control ideal and without hypoglycemia or ketosis,10 cases whose blood sugar control was not ideal and ever occurred hypoglycemia or ketosis) and 18 cases pregnancy with thrombocytopenia patients were analyzed in this study. Twenty cases normal pregnant women were taken as control at the same time. The peripheral blood of women in each group was obtained to count FNBRC and perform Wright-Giemsa stain after single density gradient centrifugation. Results There were significant differences in FNRBC number in peripheral blood of mild preeclampsia patients, severe preeclampsia patients and eclampsia patients compared with normal pregnant women in control group (P0. 05). Conclusion The FNRBC number of preeclampsia patients,eclampsia patients and GDM patients increase; moreover, the increase of FNRBC number in maternal peripheral blood is more obvious when illness is aggravated. The results suggest that increasing of FNRBC number can indicate aggravation of pregnancy complications and threat fetal life. Doctors should take effective interventions actively, and terminate pregnancy if necessary.%目的 探讨妊娠期高血压疾病、妊娠期糖尿病、妊娠合并血小板减少症时,母血中胎儿有核红细胞(fetal nucleated red blood cell,FNRBC)数量的变化.方法 选择临床确诊的妊娠期高血压疾病患者30例(其中子痫前期轻度12例,子痫前期重度12例,子痫6例),妊娠期糖尿病患者23例(其中血糖控制理想无低血糖或酮症发生13例,血糖控制

    Chronic low-grade inflammation may be involved in the pathogenesis of insulin resistance and type 2 diabetes. We examined whether a high white blood cell count (WBC), a marker of inflammation, predicts a worsening of insulin action, insulin secretory function, and the development of type 2 diabetes in Pima Indians. We measured WBC in 352 nondiabetic Pima Indians (215 men and 137 women, aged 27 +/- 6 years [means +/- SD], body fat 32 +/- 8%, WBC 8,107 +/- 2,022 cells/mm(3)) who were characterized for body composition (by hydrodensitometry or dual-energy X-ray absorptiometry), glucose tolerance (by 75-g oral glucose tolerance test), insulin action (M; by hyperinsulinemic clamp), and acute insulin secretory response (AIR; by 25-g intravenous glucose challenge). Among 272 subjects who were normal glucose tolerant (NGT) at baseline, 54 developed diabetes over an average follow-up of 5.5 +/- 4.4 years. Among those who remained nondiabetic, 81 subjects had follow-up measurements of M and AIR. Cross-sectionally, WBC was related to percent body fat (r = 0.32, P < 0.0001) and M (r = -0.24, P < 0.0001), but not to AIR (r = 0.06, P = 0.4). In a multivariate analysis, when adjusted for age and sex, both percent body fat (P < 0.0001) and M (P = 0.03) were independently associated with WBC. A high WBC value predicted diabetes (relative hazard 90th vs. 10th percentiles [95%CI] of 2.7 [1.3-5.4], P = 0.007) when adjusted for age and sex. The predictive effect of WBC persisted after additional adjustment for established predictors of diabetes, i.e., percent body fat, M, and AIR (relative hazard 2.6 [1.1-6.2], P = 0.03). After adjustment for follow-up duration, a high WBC at baseline was associated with a subsequent worsening of M (P = 0.003), but not a worsening of AIR. A high WBC predicts a worsening of insulin action and the development of type 2 diabetes in Pima Indians. These findings are consistent with the hypothesis that a chronic activation of the immune system may play a

    A wide range of patient health data is recorded in Electronic Health Records (EHR). This data includes diagnosis, surgical procedures, clinical laboratory measurements, and medication information. Together this information reflects the patient's medical history. Many studies have efficiently used this data from the EHR to find associations that are clinically relevant, either by utilizing International Classification of Diseases, version 9 (ICD-9) codes or laboratory measurements, or by designing phenotype algorithms to extract case and control status with accuracy from the EHR. Here we developed a strategy to utilize longitudinal quantitative trait data from the EHR at Geisinger Health System focusing on outpatient metabolic and complete blood panel data as a starting point. Comprehensive Metabolic Panel (CMP) as well as Complete Blood Counts (CBC) are parts of routine care and provide a comprehensive picture from high level screening of patients' overall health and disease. We randomly split our data into two datasets to allow for discovery and replication. We first conducted a genome-wide association study (GWAS) with median values of 25 different clinical laboratory measurements to identify variants from Human Omni Express Exome beadchip data that are associated with these measurements. We identified 687 variants that associated and replicated with the tested clinical measurements at pdata from the EHR provides a record of a patient's medical history, we utilized this information to further investigate the ICD-9 codes that might be associated with differences in variability of the measurements in the longitudinal dataset. We identified low and high variance patients by looking at changes within their individual longitudinal EHR laboratory results for each of the 25 clinical lab values (thus creating 50 groups - a high variance and a low variance for each lab variable). We then performed a PheWAS analysis with ICD-9 diagnosis codes, separately in the high

    The review is dedicated to an actual problem--genetic prognosis of risk of bronchial asthma development that is quite a complex aspect of studies from a methodological viewpoint. Bronchial asthma--heterogeneous disease by both etiology and clinical characteristics. At the same time genetic prognosis is based on the unity of pathogenetic mechanisms of development, though in immunological reactions that are the base of this disease, alternative variants are possible. The aim of this review is carrying out parallels between modern achievements in the field of deciphering trigger mechanisms of bronchial asthma pathogenesis and object of genetic studies based on these mechanisms. Among the examined conceptions--role of epithelial tissue in trigger mechanisms of bronchial asthma, variants of key role of immune system cells, first of all, T-helpers of various types for further development of inflammatory-effector reactions with damage characteristic for this disease. Compliance of contemporary approaches of genetic studies and novel concepts of bronchial asthma pathogenesis is shown.

    Obesity and asthma are common inflammatory conditions, having presence of both local and systemic inflammation and this relationship is not well understood. This study was undertaken to compare pulmonary function parameters, inflammatory marker like C-reactive protein (hs-CRP), exhaled nitric oxide (FENO) and atopic profile between non-obese and obese bronchial asthma patients in Indian population. The study aims to elucidate the association between the systemic and local inflammatory response relating to obesity in asthmatics. Sixty bronchial asthma patients were recruited for the study, and were divided equally into obese (BMI>30 kg/m(2)) and non-obese (BMIgroups. These were assessed for pulmonary function parameters, blood hs-CRP levels, exhaled breath analysis of nitric oxide and skin prick testing for atopic profile. The study was approved by institutional ethical committee. The mean body mass index (BMI) for the non-obese and obese group was 21.64 kg/m(2) and 34.1 kg/m(2) respectively (P = 0.001). The functional residual capacity (FRC% predicted) (100.9 ± 4.21 vs 80.40 ± 4.03; P = 0.009) and expiratory reserve volume (ERV% predicted) (95.13 ± 6.71 vs. 67.03 ± 4.54; P = 0.001) both were significantly lower in the obese group. The non-obese and obese group had hs-CRP levels of 3.01 mg/L and 4.07 mg/L, respectively; the difference being statistically insignificant (P = 0.15). Similarly, FENO levels of non-obese and obese group were 63.20 ppb and 63.75 ppb, respectively; difference was not statistically significant (P = 0.95). Atopic profile of both the groups did not differ significantly. Obesity does not appear to increase the local and systemic inflammatory responses in bronchial asthma patients in Indian population.

    To study the relationship of the incidence of bronchial dysplasia (bronchial anomalous origin and bronchial stenosis) with congenital heart disease. A total of 185 children with congenital heart disease or bronchial dysplasia were enrolled. Bronchial dysplasia was identified by the 64-MSCT conventional scanning or thin slice scanning with three-dimensional reconstruction. Forty-five children (25.3%) had coexisting bronchial dysplasia and congenital heart disease. The incidence rate of bronchial dysplasia in children with congenital heart disease associated with ventricular septal defect was higher than in those without ventricular septal defect (33.7% vs 15.0%; Pdysplasia between the children with congenital heart disease who had a large vascular malformation and who did not. Bronchial dysplasia often occurs in children with congenital heart disease. It is necessary to perform a tracheobronchial CT scanning with three-dimensional reconstruction to identify tracheobronchial dysplasia in children with congenital heart disease, especially associated with ventricular septal defect.

    Full Text Available Timothy Williamson supports the thesis that every possible entity necessarily exists and so he needs to explain how a possible son of Wittgenstein’s, for example, exists in our world:he exists as a merely possible object (MPO, a pure locus of potential. Williamson presents a short argument for the existence of MPOs: how many knives can be made by fitting together two blades and two handles? Four: at the most two are concrete objects, the others being merely possible knives and merely possible objects. This paper defends the idea that one can avoid reference and ontological commitment to MPOs. My proposal is that MPOs can be dispensed with by using the notion of rules of knife-making. I first present a solution according to which we count lists of instructions - selected by the rules - describing physical combinations between components. This account, however, has its own difficulties and I eventually suggest that one can find a way out by admitting possible worlds, entities which are more commonly accepted - at least by philosophers - than MPOs. I maintain that, in answering Williamson’s questions, we count classes of physically possible worlds in which the same instance of a general rule is applied.

    Full Text Available Bronchial atresia is a rare pulmonary developmental anomaly characterized by the presence of a focal obliteration of a segmental or lobar bronchial lumen. The lung distal to the atretic bronchus is typically emphysematous along with the presence of mucus filled ectatic bronchi (mucoceles. BA is usually asymptomatic but pulmonary infections can rarely develop in the emphysematous lung distal to the atretic bronchus. We present a unique case of chronic pulmonary aspergillosis (CPA in a patient with BA with no evidence of immune dysfunction. The patient was treated initially with voriconazole and subsequently underwent surgical excision of the involved area. On follow-up, she has done extremely well with no evidence for recurrence. In summary, we describe the first case of chronic pulmonary aspergillosis in an immunocompetent patient with bronchial atresia.

    Full Text Available Bronchial asthma is one of the widespread chronic diseases of lungs. Immune mechanisms of disorder are one of the causes which lead to pathologic changes in lungs. The aim: to determine the clinical and immunologic effectiveness of pressure adaptation to the periodical hypobaric hypoxic stimulation of treatment of children with bronchial asthma of prepubertal and pubertal periods. In the present work there were observed the clinical and immunologic parameters of 129 children with the verified atopic bronchial asthma of different degree at the remission period before and after the course of pressure adaptation to the periodical hypobaric hypoxic stimulation in conditions of the medical hypobaric pressure chamber with many seats «Ural'1». Clinic effectiveness of hypobaric hypoxic stimulation revealed in continuation of remissions and diminishing of total numerical score of asthma degree. The positive dynamic indexes of cytokine profile was observed. It revealed in reduction of IL 1_, IL 4, IL 5, IL 18 levels and stimulated production of IFN - in blood serum. The course of hypobaric hypoxic stimulation has the positive impact on the named indexes of the patients with bronchial asthma and its intensity depends on the degree of disease and of the age of the child' patient. Thus the use of pressure adaptation to the periodical hypobaric hypoxic stimulation in treatment of children's with bronchial asthma led to the immunologic positive dynamics, especially of the children of prepubertal period. Determination of the immunologic indexes and the level of the cytokines can be used as the additional tests for the evaluation of the effectiveness of pressure adaptation to the periodical hypobaric hypoxic stimulation of children.Key words: bronchial asthma, periodical hypobaric hypoxic stimulation, cytokines, children.

    We studied changes in lung volumes and in bronchial response to methacholine chloride (MC) challenge when antishock trousers (AST) were inflated at venous occlusion pressure in healthy subjects in the standing posture, a maneuver known to shift blood toward lung vessels. On inflation of bladders isolated to lower limbs, lung volumes did not change but bronchial response to MC increased, as evidenced by a greater fall in the forced expiratory volume in 1 s (FEV1) at the highest dose of MC used compared with control without AST inflation (delta FEV1 = 0.94 +/- 0.40 vs. 0.66 +/- 0.46 liter, P less than 0.001). Full inflation of AST, i.e., lower limb and abdominal bladder inflated, significantly reduced vital capacity (P less than 0.001), functional residual capacity (P less than 0.01), and FEV1 (P less than 0.01) and enhanced the bronchial response to MC challenge compared with partial AST inflation (delta FEV1 = 1.28 +/- 0.47 liter, P less than 0.05). Because there was no significant reduction of lung volumes on partial AST inflation, the enhanced bronchial response to MC cannot be explained solely by changes in base-line lung volumes. An alternative explanation might be a congestion and/or edema of the airway wall on AST inflation. Therefore, to investigate further the mechanism of the increased bronchial response to MC, we pretreated the subjects with the inhaled alpha 1-adrenergic agonist methoxamine, which has both direct bronchoconstrictor and bronchial vasoconstrictor effects.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Introduction. Bronchial hyperresponsiveness (BHR is a factor in predicting bronchial asthma independently of inflammation markers. Objective. The aims were to determine the frequency and important predictive facts of BHR and the effect of prophylaxis by Global Initiative for Asthma (GINA and National Asthma Education and Prevention Program (NAEPP on BHR in asthmatic children. Methods. BHR in 106 children was evaluated by the bronchoprovocation test with methacholine. Results. The prevalence rate of symptomatic BHR is 18% for crucial point of PC20=4.1±3.03 mg/ml and PD20=3.22±2.59 μmol methacholine. On average asthmatic children express moderate BHR, which persists even two years after administering prophylaxis. After two years bronchial reactivity is significantly smaller, the change of FEV1 is significantly smaller, the velocity of change of slope dose response curve (sDRC is faster and the provocative concentration of methacholine that causes wheezing is 2-3 times lower. A mild sDRC shows milder bronchoconstriction after two years. The fast change of bronchial reactivity in 41% of asthmatic children is contributed to aero-pollution with sulfur dioxide and/ or, possible insufficient and/or inadequate treatment during two years of administering prophylaxis. A simultaneous effect of allergens from home environment and grass and tree pollens and of excessive aero-pollution on children’s airways is important in the onset of symptomatic BHR. After two years of treatment by GINA and NAEPP children do not show asthma symptoms or show mild asthma symptoms, however bronchial sensitivity remains unchanged. Conclusion. Optimal duration of anti-inflammatory treatment in asthmatic children who show moderate bronchial hyperresponsiveness should be longer than two years.

    @@ Bronchial asthma is a disease with reversible tracheospasm and tracheostenosis due to excessively increased tracheal-bronchial reactivity induced by sensitinogen or non-sensitinogen. Although its etiology is complicated, the disease is generally caused by internal injury resulting from accumulation of phlegm in the lungs, damage to the spleen by improper diet and impairment of the kidneys by overstrain and excessive coitus;or it can be caused by six exogenous pathogenic factors, with obstruction of the airways by phlegm and upward adverse flow of the lung-qi.

    Full Text Available Forty-four patients with allergic (ABA and non-allergic (NABA variants of bronchial asthma (BA were examined to evaluate levels of key adipokines (leptin, resistin, adiponectin in sputum in different variants of BA. Adipokines in sputum and blood plasma were measured by Enzyme-Linked Immunosorbent Assay (ELISA. The indices that reflect the percentage of adipokines in sputum regarding adipokines in plasma of the same patients were worked out to evaluate the ratio of levels of corresponding adipokines in plasma and sputum in patients with BA. Two regularities are clearly seen in the study: the first - levels of proinflammatory adipokines (leptin, resistin in sputum in ABA correlate directly with indicators of respiratory function but levels of anti-inflammatory adipokines (adiponectin in sputum correlate inversely with indicators of respiratory function; the second -correlation of levels of the studied adipokines with indicators of respiratory function are almost not revealed in NABA. The first regularity reflects the important fact that the content of adipokines in bronchial secretion is to a certain extent one of regulating local mechanisms in target organ controlled system levels of corresponding adipokines in exacerbation of BA.

    It is important to examine progression to acquired immunodeficiency syndrome (AIDS) or death and its predictors among human immunodeficiency virus (HIV) infected persons before and after the introduction of the highly active antiretroviral therapy (HAART) available in Japan since 1997. The data used were from a survey of persons with HIV infected through blood coagulation factor products in Japan. Progression to AIDS or death during two periods, between January 1994 and March 1997, and between April 1997 and March 2002, were observed. The AIDS-free proportion after 3 years was 74% among 417 participants for the earlier period and 94% among 605 participants in the later one. The hazard ratio of low CD4 cell count (less than 200 cells/microL) was 50.8 for the earlier period and 4.7 for the later one compared with that of 500 cells/microL or more. After adjustment by plasma HIV RNA levels and use of antiretroviral therapy, the hazard ratios of the low CD4 cell count for the later period were still significant. The AIDS-free proportion among people with HIV infected through blood products in Japan largely increased after the introduction of HAART. The CD4 cell count remains an important predictor of future progression, but its importance might be less because of HAART.

    Fructans are dietary fibers with beneficial effects on the gastrointestinal physiology and offer a promising approach for the treatment of some metabolic disorders associated with obesity. In vitro and in vivo studies were developed to test the safety of fructans obtained from Agave tequilana Weber var. azul. Additionally, an in vivo experiment using a diet-induced obesity model was performed to compare the effect of agave fructans with different degree of polymerization (DP) profiles: agave fructans with DP > 10 (LcF), agave FOS with DP agave fructans with and without demineralization (dTF, TF) versus commercial chicory fructans (OraftiSynergy1™) on the body weight change, fat, total cholesterol, triglycerides and count of fecal Lactobacillus spp. and Bifidobacterium spp. Results showed that A. tequilana fructans were not mutagenic and were safe even at a dose of 5 g per kg b.w. Obese mice that received ScF showed a significant decrease in body weight gain, fat tissue and total cholesterol without increasing the count of fecal Bifidobacteria. Whereas, obese mice that received LcF and TF showed decreased triglycerides and an increased count of fecal Bifidobacteria. Interestingly, although obese mice that received dTF did not show changes in body weight gain, fat tissue, total cholesterol or triglycerides, they showed an increase in the count of Bifidobacteria. These results demonstrate that both the degree of polymerization and the demineralization process can influence the biological activity of agave fructans.

    Objective: To evaluate the necessity of weekly monitoring by means of leukocyte and platelet counts of patients with head and neck, chest, and pelvis cancer submitted to conventional radiotherapy. Materials and methods: A hundred and one adult patients with cancer of head and neck (n = 11), chest (n = 35) and pelvis (n = 55), submitted to radiotherapy were assessed by means of leukocyte and platelet counts on a weekly basis, with a comparison between the results before and during the treatment and in correlation with the area treated, patient's sex and age group. Results: The most significant decrease in leukocytes was observed in the fourth week, when lymphocytes, total leukocytes, neutrophils, monocytes and platelets presented a decrease of 53.5%, 26.8%, 19.4%, 22.2% and 14.6%, respectively, in comparison with the values found before the beginning of the therapy. Geometric means for pelvis during the treatment were lower than those for chest, and head and neck. Lymphocytes demonstrated to be more sensitive to radiation therapy. No alteration was found in leukocyte or platelet counts in correlation with patients' sex or age. Conclusion: Based on the results of the present study, weekly leukocyte and platelet counts do not seem to be useful in the assessment patients submitted to conventional radiotherapy for localized cancer.

    Eduardo R Alves-Junior

    Full Text Available Quantification of parasite density is an important component in the diagnosis of malaria infection. The accuracy of this estimation varies according to the method used. The aim of this study was to assess the agreement between the parasite density values obtained with the assumed value of 8,000 cells/μL and the automated WBC count. Moreover, the same comparative analysis was carried out for other assumed values of WBCs. The study was carried out in Brazil with 403 malaria patients who were infected in different endemic areas of the Brazilian Amazon. The use of a fixed WBC count of 8,000 cells/μL to quantify parasite density in malaria patients led to overestimated parasitemia and resulted in low reliability when compared to the automated WBC count. Assumed values ranging between 5,000 and 6,000 cells/μL, and 5,500 cells/μL in particular, showed higher reliability and more similar values of parasite density when compared between the 2 methods. The findings show that assumed WBC count of 5,500 cells/μL could lead to a more accurate estimation of parasite density for malaria patients in this endemic region.

    Full Text Available Introduction. The course of bronchial asthma in children is often accompanied by gastrointestinal (GI diseases associated with H.pylori infection. The presence of H.pylori leads to the activation and maintenance of inflammatory process with release of cytokines and mediators of inflammation and subsequent systemic effects. Objective: to study the peculiarities of interferon gamma (IFN-γ and interleukin (IL-4, -5 and -13 production as markers of allergic inflammation severity in children with bronchial asthma infected with H.pylori. Materials and methods. There were examined 120 children with bronchial asthma aged 6 to 18 years. Identification of H.pylori was carried out with the help of brea­thing Helic-test (LLC AMA, Russia. Serum concentrations of IFN-γ and IL‑4, -5 and -13 were determined by enzyme-linked immunoassay (Diaclone test-kits, France before and 7 days after the end of treatment for GI pathology. Statistical processing was performed using the methods of variation statistics implemented in the software package Statistica 6.1. Results. 78 children with bronchial asthma were diagnosed with GI disease, including 37 cases associated with H.pylori infection. To study the influence of H.pylori on the course of bronchial asthma, children were divided into 3 groups: I group — 37 children with bronchial asthma and GI pathology, infected with H.pylori, II — 41 H.pylori-negative children with bronchial asthma and GI pathology, III — 42 H.pylori-negative children with bronchial asthma without GI disorders. Duration of bronchial asthma in group I was 7.80 ± 0.17 years, in II — 5.90 ± 0.26 years, in group III — 3.90 ± 0.48 years (p < 0.05. The presence of H.pylori infection in children with bronchial asthma was accompanied by lower concentrations of IFN-γ compared to children of group II (8.47 ± 0.14 pg/ml and 9.69 ± 0.32 pg/ml, respectively, p < 0.05. The level of IL‑13 in the blood serum was

    The purpose of this study was to evaluate the prevalence and type of lung function disorders in Danish farmers. Three samples of farmers were drawn from a group of unselected farmers who had participated in an epidemiological study. Group I (47 persons) was a sample of the 8% of all farmers who had reported that they had asthma; group II (63 persons) was a sample of the 28% of farmers who had had wheezing, shortness of breath, or cough without phlegm; and group III (34 persons) a sample of the farmers (64% of the total) who had no asthma and no respiratory symptoms. The farmers with symptoms (groups I and II) had low mean levels of FEV1 and high values for residual volume, whereas the symptomless farmers had normal lung function and no airways obstruction. The proportion of farmers with an FEV1 below the 95% confidence limit for predicted values was 43% in group I and 23% in group II; there were none in group III. Bronchial hyperreactivity to histamine occurred in 96% of asthmatic farmers, 67% of farmers with wheezing or shortness of breath, and 59% of symptomless farmers. A low level of FEV1 was associated with the number of years in pig farming and bronchial hyperreactivity in group II but not group I or III. Most of the bronchial hyperreactivity was explained in the multiple regression analysis by a low FEV1, though this was significant only for farmers in group II. Thus farmers who reported asthma, wheezing, shortness of breath, or a dry cough in general had airways obstruction with an increased residual volume, whereas symptomless farmers had normal lung function. Severe bronchial hyperreactivity was mostly explained by a diagnosis of asthma and poor lung function, though some farmers with normal lung function and no respiratory symptoms had increased bronchial reactivity.

    Introduction The aim of this study was to assess pneumatic tube system (PTS) alteration on platelet function by the light transmission aggregometry (LTA) and whole blood aggregometry (WBA) method, and on the results of platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen. Materials and methods Venous blood was collected into six 4.5 mL VACUETTE® 9NC coagulation sodium citrate 3.8% tubes (Greiner Bio-One International GmbH, Kremsmünster, Austria) from 49 intensive care unit (ICU) patients on dual anti-platelet therapy and immediately hand carried to the central laboratory. Blood samples were divided into 2 Groups: Group 1 samples (N = 49) underwent PTS (4 m/s) transport from the central laboratory to the distant laboratory and back to the central laboratory, whereas Group 2 samples (N = 49) were excluded from PTS forces. In both groups, LTA and WBA stimulated with collagen, adenosine-5’-diphosphate (ADP), arachidonic acid (AA) and thrombin-receptor-activated-peptide 6 (TRAP-6) as well as platelet count, PT, APTT, and fibrinogen were performed. Results No statistically significant differences were observed between blood samples with (Group 1) and without (Group 2) PTS transport (P values from 0.064 – 0.968). The AA-induced LTA (bias: 68.57%) exceeded the bias acceptance limit of ≤ 25%. Conclusions Blood sample transportation with computer controlled PTS in our hospital had no statistically significant effects on platelet aggregation determined in patients with anti-platelet therapy. Although AA induced LTA showed a significant bias, the diagnostic accuracy was not influenced. PMID:28392742

    Activated bronchial epithelial cells release alarmins, including thymic stromal lymphopoietin (TSLP) that drive type 2 inflammatory responses. We hypothesize that bronchial epithelial-derived factors enhance in situ eosinophil differentiation and maturation from myeloid precursors, a process that is driven by an IL-5 rich micro-environment within asthma airways. To assess the eosinophilopoietic potential of epithelial-derived factors, eosinophil/basophil colony forming units (Eo/B-CFU) were enumerated in 14-day methylcellulose cultures of blood-derived mononuclear cells (NAMNCs) incubated with bronchial epithelial cell supernatants (BECSN) from healthy non-atopic controls (NC; n = 8), mild atopic asthmatics (MA; n = 9) and severe asthmatics (SA; n = 5). Receptor blocking antibodies were used to evaluate the contribution of alarmins. Modulation of mRNA expression of transcription factors crucial for eosinophil differentiation was evaluated. BECSN stimulated the clonogenic expansion of eosinophil progenitors, in vitro. In the presence of IL-5, Eo/B-CFU growth was significantly greater in co-cultures of BESCN from SA, compared to MA and NC. This effect was attenuated by a TSLP receptor blocking antibody but not by an ST2 antibody. Recombinant human TSLP (optimal at 100 pg/ml) stimulated significant Eo/B-CFU growth, which was significantly enhanced in presence of IL-5 (1 ng/ml). Overnight culture of CD34+ cells with IL-5 and TSLP synergistically increased GATA-2 and CEBP-alpha mRNA expression. The eosinophilopoietic potential of factors derived from bronchial epithelial cells is increased in severe asthma. Our data suggest that TSLP is a key alarmin produced by bronchial epithelial cells, which promotes in situ eosinophilopoiesis in a type 2 rich microenvironment.

    Full Text Available Life-threatening hemoptysis is one the most challenging condition encountered in critical care. Bronchial artery embolization (BAE has become an established procedure, in the management of massive and recurrent hemoptysis. Bronchial arteries have variable anatomy. The reported prevalence of bronchial arteries with an anomalous origin ranges from 8.5 -35%. We are describing two patients who presented with hemoptysis and were effectively managed with bronchial artery embolization. Both these patients had anomalous origin of bronchial artery from the internal mammary artery, one from the Right Internal Mammary Artery (RIMA and one from the Left Internal Mammary Artery (LIMA. The procedures were performed under general anesthesia. In the first case a double lumen endobronchial tube was used while in the second case, the patient was managed without tracheal intubation. The first patient was dyspnoeic; saturation was poor and was unable to maintain her airway probably due to profuse blood in her airways. We used a double lumen tube in her to isolate the diseased lung from the healthier lung. We gave her muscle relaxants and mechanical ventilation so that a stable lung field could be provided during embolization. The second patient was quite stable and comfortable while breathing room air. We decided not to interfere with his airway. A back-up plan and preparation for urgent airway control and lung isolation was done inside the catheterization laboratory.From the management point of view, an unstable patient with life-threatening hemorrhage needs airway control and lung isolation. A stable patient with minimum to moderate bleeding may be managed safely under general anesthesia with the patient spontaneously breathing.

    Young's Modulus and dynamic force moduli were measured on human bronchial airway tissues by compression. A simple and low-cost system for measuring the tensile-strengh of soft bio-materials has been built for this study. The force-distance measurements were undertaken on the dissected bronchial airway walls, cartilages and mucosa from the surgery-removed lungs donated by lung cancer patients with COPD. Young's modulus is estimated from the initial slope of unloading force-displacement curve and the dynamic force moduli (storage and loss) are measured at low frequency (from 3 to 45 Hz). All the samples were preserved in the PBS solution at room temperature and the measurements were perfomed within 4 hours after surgery. Young's modulus of the human bronchial airway walls are fond ranged between 0.17 and 1.65 MPa, ranged between 0.25 to 1.96 MPa for cartilages, and between 0.02 to 0.28 MPa for mucosa. The storage modulus are found varying 0.10 MPa with frequency while the loss modulus are found increasing from ...

    BACKGROUND: An approach to the study of the pharmacokinetics of drugs in the lung is to measure their concentrations in bronchial biopsy specimens. The main criticism of this technique is that bronchial biopsy specimens consist of more than one tissue type and that drugs are often not distributed evenly. The morphology of bronchial biopsy specimens and the distribution of water between the extracellular and the intracellular compartments is therefore important. METHODS: Fifteen subjects under...

  18. [Bronchial hyperresponsiveness and its importance for the clinician].

    Science.gov (United States)

    Mihalache, A; Fitting, J-W

    2014-11-19

    Asthma is a chronic inflammatory airway disease, characterised by bronchial hyperresponsiveness causing bronchoconstriction, and thereby provoking typical symptoms (dyspnoea, cough, wheezing). Bronchial hyperres- ponsiveness indicates a temporary airflow limitation when exposed to a bronchoconstricting stimulus. Its measurement by challenge tests can be a valuable tool for confirming or excluding asthma, as well as for evaluating the efficacy of treatment. However, the origin of bronchial hyperresponsiveness is multifactorial and the different challenge tests are not equivalent. Direct challenge tests, like methacholine, mainly reflect chronic airway remo- delling, whereas indirect tests, like mannitol, better reflect bronchial inflammation.

    Full Text Available Alcohol consumption is common problem in Uganda. Among the types of alcohols consumed include beers, spirits, liqueurs, wines and traditional brew. These alcohols are easily accessible and consumed by many people including the HIV infected patients who are on the d4T/3TC/NVP regimen. The aim of this study was to determine the effect of chronic alcohol intake on the red blood cell count (RBC and the RBC indices in the HIV-infected patients on d4T/3TC/NVP regimen. It was a case control study that used a repeated measures design model where serial measurements of the red blood cell count (RBC and RBC indices were determined at 3 month interval for 9 months. A total of 41 HIV infected patients were recruited and grouped into two arms; the control group had 21 patients and the chronic alcohol group had 20 patients. The RBC and RBC indices of the whole blood were determined using automated hematological Coulter CBC-5 Hematology Analyzer system using standard procedures. The data was sorted into alcohol-use self reporting by WHO AUDIT tool and alcohol-use biomarkers groups. It was analysed using the SAS 2003 version 9.1 statistical package with the repeated measures fixed model. The means were compared using the student t-test. The mean MCV and MCH values in the chronic alcohol use group were higher than in the control group and there was a significant difference between the 2 groups (p<0.05 for both the WHO AUDIT tool group and chronic alcohol use biomarkers group. The mean RBC count, Hct, HGB and MCHC values in both the control and chronic alcohol use groups were within the normal reference ranges for both groups though the trend was lower in alcohol group. Chronic alcohol use affects the RBC and RBC indices in the HIV infected patients on d4T/3TC/NVP treatment regimen. [Int J Basic Clin Pharmacol 2013; 2(5.000: 528-536

    Full Text Available The aim of the present study was to comparatively evaluate hemogram, blood serum components and anatomopathologic alterations in commercial layers experimentally challenged with an attenuated vaccine candidate strain (SG∆cobS∆cbiA and other two pathogenic strains (SGDcobS and SGNalr of Gallinarum (SG. In total, 280 commercial layers were randomly divided into 4 groups (G1, G2, G3 and G4. At five days of age, birds from groups G1 received approximately 107 colony forming units (CFU of SGDcobS; meanwhile birds from group G2 and G3 received the same dose of SGNalr and SG∆cobS∆cbiA, respectively. Birds from G4 were not infected. At 24 hours before (DBI and 24 hours after (1 DAI, and three (3 DAI, five (5 DAI, seven (7 DAI ten (10 DAI, and fifteen (15 DAI days after the infection, 10 birds of each group were humanely killed and blood samples collected to hematological and serum tests. Samples of liver, spleen, thymus, bursa of Fabricius, kidney and heart were also collected for the histological examination. Birds inoculated with SGDcobS and SGNalr showed similar alterations in hemogram, blood serum components and anatomopathologic exams. On the other hand, the exams of birds inoculated with SG∆cobS∆cbiA strain were similar to those of the uninfected birds. However, changes could be noticed in levels of uric acid and cholesterol during the course of the infection of birds from G3. Decrease in levels of light IgG 3 DAI was also observed in birds from this group. Pyknosis in kidney cells was a microscopic alteration found in birds from G3. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SG∆cobS∆cbiA strain.

    The pathogenesis of atherosclerosis is multifactorial, however the impact of inflammatory cells in this process is well known. Different traditional cardiovascular risk factors (CVRFs) may have specifically different effects on leukocyte subtype. Thus, these special interactions may induce different vascular involvement forms due to the altered endothelial damage and vascular repair mechanisms. The aim of the present study was to investigate whether there is any specific relationship between the leukocyte subtypes and the traditional CVRFs and to evaluate the independency of possible relationships. The study had a cross-sectional observational design. The study population consisted of the patients who underwent coronary angiography with a suspicion of coronary artery disease (CAD) at our institution in an outpatient manner. We enrolled 677 consecutive eligible patients with CAD or normal coronary arteries (NCA) and investigated the associations of traditional CVRFs, demographic properties and biochemical parameters including fasting plasma glucose (FPG), creatinine, serum uric acid level (SUA) and lipids with total circulating inflammatory cell (WBC, leukocytes) and subtype counts including neutrophils (N), lymphocytes (L) and monocytes (M). As a dependent variable, total leukocyte count and subtypes, and neutrophil/lymphocyte ratio (N/L ratio) which has been found to being related with increased vascular risk and events were investigated in the groups determined by the presence or absence of CVRFs and CAD by the univariate analyses and then multiple linear regression analyses. When we performed multiple linear regression analyses to determine the independent associations of inflammatory cell subtypes, we have found that FPG had an independent incremental association with WBC (β±SE:4.2±1.4, p=0.004) and N (β±SE:4.2±1.2, p=0.001). Current smoking had an independent incremental association with WBC and all cell subtypes (for WBC, N, L, and M: β±SE: 748±161

It subsequently spread worldwide.Investigators involved in an international collaboration have attempted to determine a specific etiology in order to redefine what is currently best described as a syndrome into a specific disease. At present, a novel coronavirus is generally accepted as the single most probable causative agent. In the case of HIV infection, monocytes/macrophages are infected early in the infection process,and the activation of monocytes/macrophages can influence the susceptibility of these cells to infection. 1Therefore, we examined the number of monocytes and the expression of CD14 and HLA-DR in the peripheral blood of patients with SARS to determine whether monocytes were involved in the pathogenesis of SARS.

    Radioaerosol inhalation imaging (RII) has been used in radionuclide pulmonary studies for the past 20 years. The method is well accepted for assessing regional ventilation because of its usefulness, easy fabrication and simple application system. To evaluate its clinical utility in the study of impaired regional ventilation in bronchial asthma, we obtained and analysed RIIs in 31 patients (16 women and 15 men; age ranging 21-76 years) with typical bronchial asthma at the Department of Radiology, Kangnam St. Mary's Hospital, Catholic University Medical college, from January, 1988 to August, 1989. Scintiscans were obtained with radioaerosol produced by a HARC(Bhabha Atomic Research Center, India) nebulizer with 15 mCi of {sup 99m}Tc-phytate. The scanning was performed in anterior, posterior and lateral projections following 5-minute inhalation of radioaerosol on sitting position. The scans were analysed and correlated with the results of pulmonary function study and the findings of chest radiography. Fifteen patients had concomitant lung perfusion image with {sup 99m}Tc-MAA. Follow-up scans were obtained in 5 patients after bronchodilator therapy. 1 he patients were divided into (1) attack type (4 patients), (2) resistant type (5 patients), (3) remittent type (10 patients) and (4) bronchitic type (12 patients). Chest radiography showed hyperinflation, altered pulmonary vascularity, thickening of the bronchial wall and accentuation of hasal interstitial markings in 26 of the 31 patients. Chest radiographs were normal in the remaining 5 patients. Regardless of type, the findings of RII were basically the same, and characterized by the deposition of radioaerosol in the central parts or in the main respiratory air ways along with mottled nonsegmental ventilation defects in the periphery. Peripheral parenchymal defects were more extensive than that of expected findings from clinical symptoms, pulmonary function test and chest radiograph. Broomstick sign was present

    A study was conducted to evaluate the level of bronchial responsiveness among workers recently exposed to vanadium pentoxide during periodical removal of ashes and clinker from the boilers of an oil-fired power station. A total of 11 male workers were examined 40-60 hours after the last exposure; male subjects, comparable as to age and smoking habits and not exposed to vanadium, were randomly chosen among the employees of the same power station as a control group. None of the subjects in the two groups had symptoms of bronchial inflammation or significant airways obstruction. However, bronchial responsiveness, investigated using a methacholine challenge test, was significantly higher in the exposed group. It is suggested that exposure to vanadium increases bronchial responsiveness even without clinical appearance of bronchial symptoms. The role of such increased level of airways responsiveness as a risk factor for chronic obstructive lung disease is speculated.

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    To study the diagnostic values of bactericidal/permeability-increasing protein (BPI), group IIA phospholipase A(2) (PLA(2)GIIA), white blood cell count (WBC), and C-reactive protein (CRP) in identifying severe sepsis upon admission in an emergency room. This was a single-centre prospective cohort study involving 525 adult patients admitted to the emergency room with suspected infection. Plasma samples were taken concurrently with the blood cultures. Forty-nine patients with severe sepsis and 476 other patients (58 with no systemic inflammatory response syndrome (SIRS) and no bacterial infection, 63 with bacterial infection but no SIRS, 53 with SIRS but no bacterial infection, and 302 with sepsis but no organ dysfunction) were evaluated. BPI and PLA(2)GIIA were measured by time-resolved fluoroimmunoassay, and CRP with an immunoturbidimetric assay. WBC was measured using an automatic cell counter. There was a positive correlation between the plasma levels of PLA(2)GIIA and CRP (Pearson's correlation coefficient 0.60, p sepsis from others (OR 1.37, 95% Cl 1.05-1.78, p = 0.019). After adjusting for confounders PLA(2)GIIA remained a significant independent predictor of severe sepsis. PLA(2)GIIA seemed to be superior to CRP, BPI, and WBC in differentiating patients with severe sepsis. BPI gave no additional information in this respect.

    Objective: In this work, effect of tamsulosin as antagonist of alpha1A and alpha1B adrenergic receptor and effect of agonists of beta2 adrenergic receptor–salbutamol in patients with increased bronchial reactibility was studied. Methods: Parameters of the lung function are determined with Body plethysmography six (6) hours after administration of tamsulosin. Raw and ITGV were registered and specific resistance (SRaw) was calculated as well. Tamsulosin was administered in per os manner as a preparation in the shape of the capsules with a brand name of “Prolosin”, produced by Niche Generics Limited, Hitchin, Herts. Results: After six (6) hours of administration of tamsulosin, results gained indicate that blockage of alpha1A and alpha1B-adrenergic receptor (0.8 mg per os) has not changed significantly (p > 0.1) the bronchomotor tonus of tracheobronchial tree in comparison to the check-up that has inhaled salbutamol agonist of adrenergic beta2 receptor (2 inh. x 0.2 mg), (p < 0.05). Blood pressure suffered no significant decrease following administration of the 0.8 mg dose of tamsulosin. Conclusion: This suggests that even after six hours of administration of tamsulosin, and determining of lung function parameters, the activity of alpha1A and alpha1B-adrenergic receptor in the smooth bronchial musculature has not changed in patients with increased bronchial reactibility.

    Full Text Available The aim of research is to study the state of circadian arterial tension profile in the patients with bronchial asthma and hypertensive disease as comorbid disease. Materials and methods. The research has been performed at 76 patients with bronchial asthma and hypertensive disease as comorbid disease (the main group and 52 patients with hypertensive disease as the comparison group. The groups were comparable with respect to the gender and age sign. Investigation was performed in the period of clinical remission. The main method used in this research was the investigation of day arterial tension profile in the time of its monitoring. Results. It has been revealed the presence of frequent and expressed change from the side of the studied indexes, especially in the patients with comorbid pathology, which were characterized by more frequent and more significant disorders from the side of diastolic blood pressure, especially at night in combination with more considerable and more rapid rise in early morning hours. The day arterial tension profile was characterized either with insufficient decline of arterial pressure at night or, opposite, with its sharp decrease. Specified disorders were increased as far as heaving of main and comorbid diseases, presence of disorders from the side of lipid exchange were not related to the phase of bronchial asthma (remission, exacerbation and level of its flow control.

    Full Text Available We studied the interaction between deoxynivalenol (DON-feeding and a subsequent pre- and post-hepatic immune stimulus with the hypothesis that the liver differently mediates the acute phase reaction (APR in pigs. Barrows (n = 44 were divided into a DON-(4.59 mg DON/kg feed and a control-diet group, surgically equipped with permanent catheters pre- (V. portae hepatis and post-hepatic (V. jugularis interna and infused either with 0.9% NaCl or LPS (7.5 µg/kg BW. Thus, combination of diet (CON vs. DON and infusion (CON vs. LPS, jugular vs. portal created six groups: CON_CONjug.-CONpor., CON_CONjug.-LPSpor., CON_LPSjug.-CONpor., DON_CONjug.-CONpor., DON_CONjug.-LPSpor., DON_LPSjug.-CONpor.. Blood samples were taken at −30, 15, 30, 45, 60, 75, 90, 120, 150, 180 min relative to infusion and analyzed for leukocytes and TNF-alpha. Concurrently, clinical signs were scored and body temperature measured during the same period. LPS as such induced a dramatic rise in TNF-alpha (p < 0.001, hyperthermia (p < 0.01, and severe leukopenia (p < 0.001. In CON-fed pigs, an earlier return to physiological base levels was observed for the clinical complex, starting at 120 min post infusionem (p < 0.05 and persisting until 180 min. DON_LPSjug.-CONpor. resulted in a lower temperature rise (p = 0.08 compared to CON_LPSjug.-CONpor.. In conclusion, APR resulting from a post-hepatic immune stimulus was altered by chronic DON-feeding.

  6. Differential white cell count by centrifugal microfluidics.

    Energy Technology Data Exchange (ETDEWEB)

    Sommer, Gregory Jon; Tentori, Augusto M.; Schaff, Ulrich Y.

    2010-07-01

    We present a method for counting white blood cells that is uniquely compatible with centrifugation based microfluidics. Blood is deposited on top of one or more layers of density media within a microfluidic disk. Spinning the disk causes the cell populations within whole blood to settle through the media, reaching an equilibrium based on the density of each cell type. Separation and fluorescence measurement of cell types stained with a DNA dye is demonstrated using this technique. The integrated signal from bands of fluorescent microspheres is shown to be proportional to their initial concentration in suspension. Among the current generation of medical diagnostics are devices based on the principle of centrifuging a CD sized disk functionalized with microfluidics. These portable 'lab on a disk' devices are capable of conducting multiple assays directly from a blood sample, embodied by platforms developed by Gyros, Samsung, and Abaxis. [1,2] However, no centrifugal platform to date includes a differential white blood cell count, which is an important metric complimentary to diagnostic assays. Measuring the differential white blood cell count (the relative fraction of granulocytes, lymphocytes, and monocytes) is a standard medical diagnostic technique useful for identifying sepsis, leukemia, AIDS, radiation exposure, and a host of other conditions that affect the immune system. Several methods exist for measuring the relative white blood cell count including flow cytometry, electrical impedance, and visual identification from a stained drop of blood under a microscope. However, none of these methods is easily incorporated into a centrifugal microfluidic diagnostic platform.

    Full Text Available Bronchial webs are thin, membrane-like diaphragms that may obstruct the airway. Several congenital cases have been reported. Though rare, the true incidence of these lesions is probably underestimated because many of them are unrecognized. The case of a 71-year-old woman with an acquired bronchial web causing right main stem bronchus obstruction that went unrecognized for 47 years post-trauma is reported. The lesion was successfully treated using rigid bronchoscopy with laser therapy, balloon dilation and stent placement. This is the first reported case of an acquired bronchial web formation. It is also the first reported case that was successfully treated with this technique.

    To describe the radiological features of pulmonary tuberculosis (TB) in patients infected with human immunodeficiency virus (HIV) and its correlation with the blood CD4 cell count. We present 44 HIV+patients, 24 with CD4 cell counts of less than 200 cells/mm''3 (group A) and 20 in whom the CD4 counts surpassed this level (group B). We also assessed the chest x-ray images to determine whether or not there was any correlation with the blood CD4 cell counts. Fisher's exact test was used for the statistical study of the differences in the radiological findings in the two groups. The incidence of atypical features was significantly greater in the patients with CD4 cell counts of less than 200 cells/mm''3 (group A) than in those with CD4 counts of over 200 cells/mm''3 (group B). Among HIV+patients, those with a more intact immune status were more likely to present lung x-ray images typical of post-primary TB, with cavitary lesions in upper lobes. The group of patients in whom the immune deficiency was more marked showed a greater incidence of atypical pulmonary findings, more characteristics of primary TB. (Author)

    To describe a new CT perfusion technique for assessing the dual blood supply in lung cancer and present the initial results. This study was approved by the institutional review board. A CT protocol was developed, and a dual-input CT perfusion (DI-CTP) analysis model was applied and evaluated regarding the blood flow fractions in lung tumours. The pulmonary trunk and the descending aorta were selected as the input arteries for the pulmonary circulation and the bronchial circulation respectively. Pulmonary flow (PF), bronchial flow (BF), and a perfusion index (PI, = PF/ (PF + BF)) were calculated using the maximum slope method. After written informed consent was obtained, 13 consecutive subjects with primary lung cancer underwent DI-CTP. Perfusion results are as follows: PF, 13.45 {+-} 10.97 ml/min/100 ml; BF, 48.67 {+-} 28.87 ml/min/100 ml; PI, 21 % {+-} 11 %. BF is significantly larger than PF, P < 0.001. There is a negative correlation between the tumour volume and perfusion index (r = 0.671, P = 0.012). The dual-input CT perfusion analysis method can be applied successfully to lung tumours. Initial results demonstrate a dual blood supply in primary lung cancer, in which the systemic circulation is dominant, and that the proportion of the two circulation systems is moderately dependent on tumour size.

  16. Peripheral blood neutrophilia as a biomarker of ozone-induced pulmonary inflammation.

    Directory of Open Access Journals (Sweden)

    Jenny A Bosson

    Full Text Available BACKGROUND: Ozone concentrations are predicted to increase over the next 50 years due to global warming and the increased release of precursor chemicals. It is therefore urgent that good, reliable biomarkers are available to quantify the toxicity of this pollutant gas at the population level. Such a biomarker would need to be easily performed, reproducible, economically viable, and reflective of ongoing pathological processes occurring within the lung. METHODOLOGY: We examined whether blood neutrophilia occurred following a controlled ozone challenge and addressed whether this could serve as a biomarker for ozone-induced airway inflammation. Three separate groups of healthy subjects were exposed to ozone (0.2 ppm, 2h and filtered air (FA on two separate occasions. Peripheral blood samples were collected and bronchoscopy with biopsy sampling and lavages was performed at 1.5h post exposures in group 1 (n=13, at 6h in group 2 (n=15 and at 18h in group 3 (n=15. Total and differential cell counts were assessed in blood, bronchial tissue and airway lavages. RESULTS: In peripheral blood, we observed fewer neutrophils 1.5h after ozone compared with the parallel air exposure (-1.1±1.0x10(9 cells/L, p<0.01, at 6h neutrophil numbers were increased compared to FA (+1.2±1.3x10(9 cells/L, p<0.01, and at 18h this response had fully attenuated. Ozone induced a peak in neutrophil numbers at 6h post exposure in all compartments examined, with a positive correlation between the response in blood and bronchial biopsies. CONCLUSIONS: These data demonstrate a systemic neutrophilia in healthy subjects following an acute ozone exposure, which mirrors the inflammatory response in the lung mucosa and lumen. This relationship suggests that blood neutrophilia could be used as a relatively simple functional biomarker for the effect of ozone on the lung.

    Congenital lung malformations are increasingly detected before birth. However, bronchial atresia is rarely identified in utero and not always recognized in neonates. There are two types of atresia: (1) proximal, located at the level of the mainstem or the proximal lobar bronchi, which is extremely rare and usually lethal during pregnancy, causing a tremendous volume increase of the distal involved lung with secondary hypoplasia of the normal lung, and (2) peripheral, located at the segmental/subsegmental bronchial level, which may present as an isolated lesion or as part of a complex congenital malformation. Prenatal findings are mostly nonspecific. Postnatal exams show overinflated lung areas and focal bronchial dilations. The typical fluid-filled bronchoceles are not always observed in neonates but develop progressively in the first months of life. This pictorial essay describes the spectrum of imaging findings of bronchial atresia in fetuses, neonates and infants. (orig.)

    Full Text Available Background. The control of severe bronchial asthma, such as corticosteroid-resistant asthma, is difficult. It is also possible that immunosuppressive agents would be effective for bronchial asthma. Case Summary. A 55-year-old Japanese female presented with severe bronchial asthma controlled with tacrolimus. She had been diagnosed with bronchial asthma during childhood. Her asthma worsened, and a chest radiograph showed atelectasis of the left lung. Bronchoscopy revealed the left main bronchus to be obstructed with viscous sputum consisting of 82% neutrophils and no eosinophils. The atelectasis did not improve with corticosteroid treatment, but was ameliorated by administration of tacrolimus. Discussion. This patient had severe asthma due to neutrophilic inflammation of the airways. Tacrolimus is effective for treating severe asthma, for example, in corticosteroid-resistant cases.

    Full Text Available   Introduction: To assess the efficacy and safety of bronchial artery embolization in the treatment of massive hemoptysis.   Materials and Methods: A retrospective study on 46 patients (26 males and 20 females who were referred to the Razavi Hospital from April 2009 to May 2012 with massive hemoptysis and had bronchial artery embolization procedures. General characteristics of the patients including age, gender, etiology, and thorax computed tomograms, findings of bronchial angiographic, results of the embolization, complications related to bronchial artery embolization and clinical outcome during follow-up were reviewed. Results: The etiology included previous pulmonary tuberculosis in 20 cases, previous tuberculosis with bronchiectasis in 16 cases, bronchiectasis in 6 cases, and active pulmonary tuberculosis in one case. No identifiable causes could be detected in three patients. Moreover, massive hemoptysis was successfully and immediately controlled following the embolization procedure in all patients. One patient developed recurrent hemoptysis during one month following the procedure and was treated by re-embolization. No major procedure–related complication such as bronchial infarction was identified However none of the patientsexperienced neurological complications. Conclusion: Bronchial artery embolization is a safe and effective means of controlling massive hemoptysis and should be regarded as the first-line treatment for this condition.

    The authors discuss the efficacy of methacholine challenge to discriminate fit subjects to military service. We evaluated the relation between bronchial hyperreactivity and clinical symptoms, airways caliber and atopic status in a group of italian conscripts who reported to have bronchial asthma. Five-hundred-four subjects were studied. Bronchial hyperreactivity was measured by methacholine test, and atopic status was assessed by skin-tests. A measurable PC20 FEV1 was detected in 424 subjects. On the basis of the methacholine threshold concentration the overall sample was divided in four categories. The four categories differed as regards onset of disease, lung function and skin reactivity towards Dermatophagoides Pter, whereas no difference was found as regards skin reactivity towards Grass. In the group evaluated in spring, the four categories differed as regards skin reactivity towards Grass. In conclusion we found that bronchial hyperreactivity is related to clinical history, lung function and atopic status; the measurement of bronchial hyperreactivity is important to evaluate conscripts referring bronchial asthma.

    The prevalence of allergic respiratory diseases such as bronchial asthma has increased in recent years, especially in industrialized countries. A change in the genetic predisposition is an unlikely cause of the increase in allergic diseases because genetic changes in a population require several generations. Consequently, this increase may be explained by changes in environmental factors, including indoor and outdoor air pollution. Over the past two decades, there has been increasing interest in studies of air pollution and its effects on human health. Although the role played by outdoor pollutants in allergic sensitization of the airways has yet to be clarified, a body of evidence suggests that urbanization, with its high levels of vehicle emissions, and a westernized lifestyle are linked to the rising frequency of respiratory allergic diseases observed in most industrialized countries, and there is considerable evidence that asthmatic persons are at increased risk of developing asthma exacerbations with exposure to ozone, nitrogen dioxide, sulphur dioxide and inhalable particulate matter. However, it is not easy to evaluate the impact of air pollution on the timing of asthma exacerbations and on the prevalence of asthma in general. As concentrations of airborne allergens and air pollutants are frequently increased contemporaneously, an enhanced IgE-mediated response to aeroallergens and enhanced airway inflammation could account for the increasing frequency of allergic respiratory allergy and bronchial asthma. Pollinosis is frequently used to study the interrelationship between air pollution and respiratory allergy. Climatic factors (temperature, wind speed, humidity, thunderstorms, etc) can affect both components (biological and chemical) of this interaction. By attaching to the surface of pollen grains and of plant-derived particles of paucimicronic size, pollutants could modify not only the morphology of these antigen-carrying agents but also their allergenic

Storage temperature influenced leukocytes and erythrocytes counts, which showed lower values at room temperature. Hemoglobin, PCV, platelet and PCT did not change significantly. The changes observed did not compromise the results obtained by automatic cell counter, showing that blood samples stored for two days remained in good condition for processing, especially when stored under refrigeration.

    The aim of our work was the study of macro-and microelemensts characteristics of the state of the blood serum of children with asthma, depending on the severity. A total of 107 children aged 10 to 18 years with asthma in the acute stage. The results of the proposed asthma control test (GINA, 2011) to the level of asthma control the children were distributed as follows: 34 (31.8%)--with controlled, 47 (43.9%)--partly controlled and 26--with uncontrolled bronchial asthma. Investigation of serum trace elements were determined by atomic absobtsionnoy spectrophotometry. Found that with varying degrees of control of asthma changes were reduction of magnesium, zinc, when excessive amounts of copper and calcium. We show some dizelements in patients with nontrol bronhial asthma. The most pronounced manifestation dyzelements documented in patients with uncontrolled asthma. It is with same with uncontrolled asthma, there are marked hypoxic change, energy shortage, bronchial hyperreactivity, as a result of increasing stress level of response to an antigen, reduce antioxidant enzyme systems, immune system dysfunction. This changes in the macro-and microelement composition of the blood significantly reduce the reserves of the immune system, chronic inflammatory processes in the bronches, which exacerbates the severity of the disease, which in practice requires a differential diagnosis, comprehensive treatment based on identified dyzelements states.

    Full Text Available A 56-year-old woman was referred to our hospital because of dyspnea, wheezing, and a productive cough. Eight years before presentation, bronchial asthma was diagnosed and the patient received inhaled corticosteroids plus antiasthmatic agents (a long-acting inhaled p2-agonist, leukotriene modifiers, and theophylline. Chest radiography showed small diffuse nodular shadows, and a computed tomographic scan showed thickening of the bronchi and bronchioles, with diffuse centrilobular nodules in both lung fields. A blood test and microscopic examination of the bronchoalveolar fluid revealed marked eosinophilia. Transbronchial lung biopsy and transbronchial biopsy showed eosinophilic bronchitis and bronchiolitis. After treatment with oral prednisolone (40 mg daily and inhaled corticosteroids, the symptoms, blood eosinophilia, and radiographic findings improved. Recently, several similar cases of eosinophilic bronchiolitis have been reported. Studies of further cases and elucidation of the pathophysiology of eosinophilic bronchiolitis are necessary to establish a concept for this disease and to determine whether it should be classified as a subtype of bronchial asthma or as a distinct entity.

    Objective To analyze the hematopoietic cell counts in 4711 cord blood unites and explore the relationship between the cell counts and the therapeutic effect of umbilical cord blood transplantation (UCBT). Methods The distribution of total nucleated cells (TNC) and the absolute CD34 + cells counts were analyzed in 4711 cord blood unites. Meanwhile, the differences among hematopoietic cells input, HLA disparity, gender, age, weight, the type of the disease as well as the survival rates were investigated. Results The median counts of TNC and CD34+ cells were 1. 14 × 109 and 4. 06 × 10, respectively, 93.2% of frozen cord blood was suitable for the transplantation in the patients with weight less than 50kg; the engraft rate was 84. 3% (75/89). Neutrophil cells reconstitution at 0. 5 × 109/L, platelet reconstitution at 20 × 109/L and 50 × 109/L occurred at the 17th, 34th and 46th days of UCBT, respectively. Among 75 engrafted cases, 47 patients got complete remission, 26 patients died and 2 patients relapsed. The incidences of acute graft-versus-host disease (GVHD) with grade Ⅰ -Ⅱ, Ⅲ-Ⅳ and chronic GVHD were 54. 7%, 20. 0% and 9. 3%, respectively. The risk factors of engraftment included age, the counts of TNC and CD34 + cells, the overall survival rate was related to the factors including age, weight and the counts of TNC and CD34 +cells. Conclusions Umbilical cord blood could be considered as the source of hematopoietic stem cells and used for the transplantation of the childhood and adult patients with leukemia when there is no acceptably matched bone marrow donor. The cell counts of TNC and CD34 + cells are useful reference index for the selection of cord blood in UCBT.%目的 分析4711份库存脐血造血细胞含量及探讨脐血造血细胞含量与白血病脐血移植疗效的关系.方法 分析4711例库存脐血总有核细胞数(NC)和CD34+细胞数分布情况,探讨不同的造血细胞输入量、供受者HLA不相合数、受者性别、

    Full Text Available Infection with respiratory viruses, including rhinoviruses, influenza virus, and respiratory syncytial virus, exacerbates asthma, which is associated with processes such as airway inflammation, airway hyperresponsiveness, and mucus hypersecretion. In patients with viral infections and with infection-induced asthma exacerbation, inflammatory mediators and substances, including interleukins (ILs, leukotrienes and histamine, have been identified in the airway secretions, serum, plasma, and urine. Viral infections induce an accumulation of inflammatory cells in the airway mucosa and submucosa, including neutrophils, lymphocytes and eosinophils. Viral infections also enhance the production of inflammatory mediators and substances in airway epithelial cells, mast cells, and other inflammatory cells, such as IL-1, IL-6, IL-8, GM-CSF, RANTES, histamine, and intercellular adhesion molecule-1. Viral infections affect the barrier function of the airway epithelial cells and vascular endothelial cells. Recent reports have demonstrated augmented viral production mediated by an impaired interferon response in the airway epithelial cells of asthma patients. Several drugs used for the treatment of bronchial asthma reduce viral and pro-inflammatory cytokine release from airway epithelial cells infected with viruses. Here, I review the literature on the pathogenesis of the viral infection-induced exacerbation of asthma and on the modulation of viral infection-induced airway inflammation.

    A prospective survey aiming to study the predictive value of bronchial histamine challenge was performed on 151 patients with a forced expiratory volume1 (FEV1) above 60% of predicted. According to variations in peak expiratory flow rate (PEFR) and medical history the patients were classified...... as asthmatics (n = 97) or non-asthmatics (n = 54). The diagnostic properties of the challenge were calculated using the statement of Baye. Considering PC20 values below 4.00 mg/ml as positive, the predictive value of a positive test was about 0.80 and the predictive value of a negative about 0.76. When PC20...... was below 0.125 mg/ml the predictive value of a positive test was 1.00, but an increase in PC20 in the range from 4.00 to 16 mg/ml did not increase the predictive value of a negative test. In this study the prevalence of asthma was about 0.6. We therefore conclude that bronchial histamine challenge...

    We studied subvocal counting in two pure anarthric patients. Analysis showed that they performed definitively worse than normal subjects free to articulate subvocally and their scores were in the lower bounds of the performances of subjects suppressing articulation. These results suggest that subvocal counting is impaired after anarthria.

    Full Text Available Techniques that analyze biological remains from sediment sequences for environmental reconstructions are well established and widely used. Yet, identifying, counting, and recording biological evidence such as pollen grains remain a highly skilled, demanding, and time-consuming task. Standard procedure requires the classification and recording of between 300 and 500 pollen grains from each representative sample. Recording the data from a pollen count requires significant effort and focused resources from the palynologist. However, when an adaptation to the recording procedure is utilized, efficiency and time economy improve. We describe EcoCount, which represents a development in environmental data recording procedure. EcoCount is a voice activated fully customizable digital count sheet that allows the investigator to continuously interact with a field of view during the data recording. Continuous viewing allows the palynologist the opportunity to remain engaged with the essential task, identification, for longer, making pollen counting more efficient and economical. EcoCount is a versatile software package that can be used to record a variety of environmental evidence and can be installed onto different computer platforms, making the adoption by users and laboratories simple and inexpensive. The user-friendly format of EcoCount allows any novice to be competent and functional in a very short time.

    There have been many reports on lung cancer among chromate workers. Chromate compounds are thought to be a carcinogen and lung cancer among chromate workers is considered one of the occupational lung cancers. Recently, it is debated that metaplastic and hyperplastic changes of bronchial epithelium are revealed or not to the development of bronchogenic carcinoma. Histopathological study on changes of bronchial epithelium among chromate workers was performed in order to clarify the effect of chromate compounds to bronchial epithelium. The subjects were 14 cases of lung cancer among chromate workers. As a control, 18 cases of non cancer among chromate workers. Lung tissue which was obtained at necropsy or surgery was fixed by formalin and was produced cross-sections and was stained on Haematoxylin-Eosin. The results were as follows. Of examined 235 cross-sections, basal cell hyperplasia of bronchial epithelium was found in 13 percent. Squamous metaplasia was found in 29 percent, on the contrary, atypical metaplastic changes were observed in 34 percent. Of four cases of carcinoma in situ and two cases of small invasive carcinoma, four cases revealed development from atypical squamous metaplasia to precancerous changes. These cases developed invasive carcinoma from atypical squamous metaplasia for a long period, of which were found by successive exfoliative cytology of sputum. From these findings, it was concluded that inhalation of chromate dust affected bronchial epithelium and caused highly atypical squamous metaplasia which developed to carcinoma in situ and finally to invasive carcinoma.

  19. Connective Tissue Growth Factor Expression in Human Bronchial Epithelial Cells

    Connective tissue growth factor (CTGF) is a cysteine-rich protein that promotes extracellular matrix deposition. CTGF is selectively induced by transforming growth factor β and des-Arg kallidin in lung fibroblasts and increases steady-state mRNA levels of α type I collagen, 5α-integrin and fibronectin in fibroblasts. Bronchial epithelial cells have been proposed to functionally interact with lung fibroblasts. We therefore investigated if bronchial epithelial cells are able to synthesize CTGF. Human bronchial epithelial cells were grown to subconfluence in standard growth media. Proliferating cells grown in small airway growth media were harvested following starvation for up to 24 h. Expression of CTGF transcripts was measured by PCR. Immunocytochemistry was also completed using a commercially available antibody.The cells expressed readily detectable CTGF transcripts. Starvation of these cells resulted in a quantitative decline of CTGF transcripts. Direct sequencing of the PCR product identified human CTGF. Immunocytochemistry confirmed intracellular CTGF in the cells and none in negative control cells. We conclude that bronchial epithelial cells could be a novel source of CTGF. Bronchial epithelial cell-derived CTGF could thus directly influence the deposition of collagen in certain fibrotic lung diseases.

    To compare the effectiveness of high-frequency jet ventilation via Wei jet nasal airway and controlled ventilation with improved laryngeal mask airway during bronchial thermoplasty. Twenty-eight patients undergoing bronchial thermoplasty were equally divided into two groups: group A (high-frequency jet ventilation through Wei jet nasal airway) and group B (controlled ventilation with improved laryngeal mask airway). Pulse oxygenation,heart rate,and mean arterial blood pressure were recorded after entering the operating room (T0), 1 minute after administration/induction (T1), bronchoscope inserting (T2), 15 minutes (T3)/30 minutes (T4)/45 minutes (T5) after ventilation,at the end of the operation (T6), and at the recovery of patients' consciousness (T7). The pH,arterial oxygen partial pressure,and arterial carbon dioxide partial pressure were recorded at T0, T4, and T6. The endoscope indwelling duration,operative time,patients' awakening time,adverse events during anesthesia,satisfactions of patients and operators, anesthesic effectiveness were also recorded. The arterial carbon dioxide partial pressur in group A at T4 and T6 were significantly higher than in group B (P<0.05). The pH in group A at T4 and T6 was significantly lower than in group B (P<0.05). The endoscope indwelling duration and the operative time in group B were significantly shorter than in group A (P<0.05) while the recovery of consciousness in group B was significantly longer than in group A (P<0.05). The satisfaction for operators and the efficacy of anesthesia in group B were better than in group A (P<0.05). The number of adverse events in group B was significantly smaller than in group A (P<0.05). The improved laryngeal mask airway with controlled ventilation is more suitable for bronchial thermoplasty.

  1. Exhaled flow monitoring can detect bronchial flap-valve obstruction in a mechanical lung model.

    Flap-valve obstruction to expiratory flow (V) in a major bronchus can result from inspissated secretions, blood, or foreign body. During inhalation, increasing airway caliber preserves inspired V past the obstruction; during exhalation, decreasing airway diameter causes airflow obstruction and even frank gas trapping. We reasoned that the resultant sequential, biphasic exhalation of the lungs would be best detected by measuring exhaled V versus time. Accordingly, we designed an airway obstruction element in a mechanical lung model to examine flap-valve bronchial obstruction. A mechanical lung simulator was ventilated with a pressure-limited flow generator, where f = 10/min, tidal volume = 850 mL, and respiratory compliance = 40 mL/cm H2O. Airway V (pneumotachometer) and pressure (P) were digitally sampled for 1 min. Then, the circumference of the diaphragm in a respiratory one-way valve was trimmed to generate unidirectional resistance to expiratory V. Measurement sequences were repeated after this flap-valve was interposed in the right "main-stem bronchus." Integration of airway V versus time generated changes in lung volume. During flap-valve obstruction of the right bronchus, the V-time plot revealed preservation of peak expired flow from the normal lung, followed by retarded and decreased flow from the obstructed right lung. Gas trapping of the obstructed lung occurred during conditions of decreased expiratory time and increased expiratory resistance. Airway P could not differentiate between bronchial and tracheal flap-valve obstruction because P decreased abruptly in both conditions. The flow-volume loop displayed less distinctive changes than the flow-time plot, in part because the flow-volume loop was data (flow) plotted against its time integral (volume), with loss of temporal data. In this mechanical lung model, we conclude that bronchial flap-valve obstruction was best detected by the flow-time plot, which could measure the sequential emptying of the

    Manual reticulocyte counts were examined under light microscopy, using the property whereby supravital stain precipitates residual ribosomal RNA versus the automated flow methods, with the suggestion that in the latter there is greater precision and an ability to determine both mature and immature reticulocyte fractions. Three hundred and forty-one venous blood samples of patients were analyzed of whom 224 newborn and the rest adults; 51 males and 66 females, with ages between 0 and 89 years, as part of the laboratory routine for hematological examinations at the Clinical Laboratory of the Hospital Universitário do Oeste do Paraná. This work aimed to compare manual and automated methodologies for reticulocyte countings and evaluate random and systematic errors. The results obtained showed that the difference between the two methods was very small, with an estimated 0·4% systematic error and 3·9% random error. Thus, it has been confirmed that both methods, when well conducted, can reflect precisely the reticulocyte counts for adequate clinical use.

  3. Evaluation of the Xpert Carba-R (Cepheid) Assay Using Contrived Bronchial Specimens from Patients with Suspicion of Ventilator-Associated Pneumonia for the Detection of Prevalent Carbapenemases

    There is a critical need for rapid diagnostic methods for multidrug-resistant (MDR) pathogens in patients with a suspicion of ventilator-associated pneumonia (VAP). The Xpert Carba-R detects 5 targets for carbapenemase-producing organisms (blaKPC, blaNDM, blaVIM, blaOXA-48, and blaIMP-1). Our objective was to evaluate the performance of this assay directly on bronchial aspirates and to correlate the cycle number for a positive result (Ct) with the bacterial count. Bronchial aspirates from patients with a suspicion of VAP were spiked with a dilution of 1 of 4 MDR organisms carrying the resistance genes detected by the test prepared to a final concentration of 102−105 cfu/mL. We used a ROC curve and provided areas under the curve (AUC) with their 95% confidence intervals (CI). A point of maximum sensitivity (Se) and specificity (Sp) was derived and validity indices were calculated. One hundred contrived tests were performed. Se and Sp were 100% for all bacterial counts. A positive sample with a Ct ≤24.7 corresponded to a count ≥105 cfu/mL; if the Ct was within the range >24.7-≤26.9, this corresponded to a count ≥104 cfu/mL. When the Ct was >26.9, this corresponded to a count <104 cfu/mL. The Xpert Carba-R detects carbapenemase-producing organisms directly in contrived bronchial aspirates. Still, an important issue to consider is that the number of gene copies may vary according to many factors in vivo. If confirmed in further studies, the strong correlation observed between Ct values and the results of semiquantitative cultures suggests this test could serve to differentiate between infection and colonization in routine clinical practice.

    We herein report a case of recurrent pneumothorax associated with congenital bronchial atresia. A 26-year-old male presented with chest pain. Chest roentgenograms showed left pneumothorax, a left apical bulla and an area of hyperlucency in the left upper lung field, and chest computed tomography revealed a discontinuation of the left superior bronchus. Additionally, both ventilation and perfusion scintigraphy showed a defect in the left superior segment. A thoracoscopy-assisted left superior segmentectomy was performed, and a pathological examination indicated left superior segmental bronchial atresia, which might have predisposed the peripheral lung to emphysematous conditions. No relapse was observed 6 months after the operation. Although this entity is rare, congenital bronchial atresia should be considered in the differential diagnosis when a patient has suffered from a recurrent spontaneous pneumothorax.

In present investigation, we studied influence of body-oriented psychotherapeutic methods directed towards clinico-immunological parameters and special psychological features of the patients with bronchial asthma, i.e., decrease in alexithymia, as an important pathogenetic factor of bronchial asthma, and improvement in motor coordination and interhemispheric interactions in motor sphere. We investigated 38 patients (18 men and 20 women, while discriminating those patients who underwent a course of body-oriented psychotherapy, and a group of comparison, who did not undergo similar therapy. When observing conventional standards of randomization according to sex, age, clinical variants, and disease severity, some heterogeneity of these groups was revealed. In general, the people with active life attitude, being ready to work with a psychologist, possessed special features both in psychological and immunological spheres.

    Abelian orbifolds of C^3 are known to be encoded by hexagonal brane tilings. To date it is not known how to count all such orbifolds. We fill this gap by employing number theoretic techniques from crystallography, and by making use of Polya's Enumeration Theorem. The results turn out to be beautifully encoded in terms of partition functions and Dirichlet Series. The same methods apply to counting orbifolds of any toric non-compact Calabi-Yau singularity. As additional examples, we count the orbifolds of the conifold, of the L^{aba} theories, and of C^4.

    Purpose: We aimed to retrospectively evaluate bronchial and nonbronchial systemic arteries using multi-detector row helical computed tomographic (MDCT) angiography in patients with pulmonary disorders. Materials and Methods: Thirty-nine patients (24 men, 15 women; mean age, 63.4 years; range, 20-82 years) with congenital and acquired pulmonary disorders of the bronchial and nonbronchial systemic arteries underwent multi-detector row helical computed tomographic angiography of the thorax using a 16-detector row scanner. Each of these patients had experienced an episode of hemoptysis. Computed tomographic angiogram data, which included maximum intensity projections, multiplanar reconstruction, and three-dimensional volume-rendered images, were used to retrospectively analyse the characteristics of the bronchial and nonbronchial systemic arteries. Results: We identified a total of 128 bronchial arteries (76 on the right side and 52 on the left) in 39 patients. We detected 42 nonbronchial systemic artery branches, including 19 internal mammary artery branches, 8 subclavian artery branches, 8 inferior phrenic artery branches, 5 intercostal artery branches, 1 thyrocervical trunk branch, and 1 celiac trunk branch. Thirty-five dilated and tortuous nonbronchial systemic arteries entered into the lung parenchyma and extended down to the lesions. Every case, except the one case of sequestration, was associated with pleural thickening where the vascular structures passed through the extrapleural fat. Conclusions: The variations in both the bronchial artery anatomy and the location and type of the nonbronchial arteries were great. Nonbronchial arteries may be a significant source of hemoptysis. MDCT angiography can be used to detect detailed anatomical information about the origins and courses of bronchial and nonbronchial systemic arteries and their pathophysiologic features.

  13. Counting Belief Propagation

    Kersting, Kristian; Natarajan, Sriraam

    2012-01-01

    A major benefit of graphical models is that most knowledge is captured in the model structure. Many models, however, produce inference problems with a lot of symmetries not reflected in the graphical structure and hence not exploitable by efficient inference techniques such as belief propagation (BP). In this paper, we present a new and simple BP algorithm, called counting BP, that exploits such additional symmetries. Starting from a given factor graph, counting BP first constructs a compressed factor graph of clusternodes and clusterfactors, corresponding to sets of nodes and factors that are indistinguishable given the evidence. Then it runs a modified BP algorithm on the compressed graph that is equivalent to running BP on the original factor graph. Our experiments show that counting BP is applicable to a variety of important AI tasks such as (dynamic) relational models and boolean model counting, and that significant efficiency gains are obtainable, often by orders of magnitude.

    Characterizing rates of occurrence of various features of a signal is of great importance in numerous types of physical measurements. Such signal features can be defined as certain discrete coincidence events, e.g. crossings of a signal with a given threshold, or occurrence of extrema of a certain amplitude. We describe measuring rates of such events by means of analog multivariate counting analyzers. Given a continuous scalar or multicomponent (vector) input signal, an analog counting analyzer outputs a continuous signal with the instantaneous magnitude equal to the rate of occurrence of certain coincidence events. The analog nature of the proposed analyzers allows us to reformulate many problems of the traditional counting measurements, and cast them in a form which is readily addressed by methods of differential calculus rather than by algebraic or logical means of digital signal processing. Analog counting analyzers can be easily implemented in discrete or integrated electronic circuits, do not suffer fro...

    Full Text Available Abstract. A study of leukocyte regulation system in patients with exacerbated bronchial asthma (BA was performed by means of measuring spontaneous and induced production of certain cytokines (IL-4, IL-1b, IL-10 and IFNg in whole blood, and drawing some specific coefficients reflecting production of the cytokines, as compared to control values. Group 1 consisted of mixed-type BA patients, with mild clinical manifestations at exacerbation stage. A control group included twelve healthy persons. The cytokine network was evaluated according to spontaneous production of cytokines (IL-4, IL-1b, IL-10 and IFNg, or their induction with standard mitogens (PHA and E. coli LPS. The results obtained have shown that in BA as a clinical model of chronic inflammation, synthesis and activation of the cytokines depend on the phase of disease. At stage of exacerbation, an imbalance occurs between pro- and anti-inflammatory cytokines, with predominance of anti-inflammatory IL-10, which is targeted to suppression of bronchial inflammation.

    Full Text Available Abstract Background Asthma is characterised by increased numbers of Th2-like cells in the airways and IgE secretion. Generation of Th2 cells requires interleukin (IL-4 and IL-13 acting through their specific receptors and activating the transcription factor, signal transducer and activator of transcription 6 (STAT6. STAT6 knockout mice fail to produce IgE, airway hyperresponsiveness and bronchoalveolar lavage eosinophilia after allergen sensitisation, suggesting a critical role for STAT6 in allergic responses. Methods We have investigated the expression of STAT6 in peripheral blood T-lymphocytes, alveolar macrophages and bronchial biopsies from 17 normal subjects and 18 mild-moderate steroid-naïve stable asthmatic patients. Results STAT6 expression was variable and was detected in T-lymphocytes, macrophages and bronchial epithelial cells from all subjects with no difference between normal and stable asthmatic subjects. Conclusions STAT6 expression in different cells suggests that it may be important in regulating the expression of not only Th2-like cytokines in T cells of man, but may also regulate STAT-inducible genes in alveolar macrophages and airway epithelial cells.

    In liquid scintillation counting (LSC) we use the process of luminescense to detect ionising radiation emit$ed from a radionuclide. Luminescense is emission of visible light of nonthermal origin. 1t was early found that certain organic molecules have luminescent properties and such molecules are used in LSC. Today LSC is the mostwidespread method to detect pure beta-ernitters like tritium and carbon-14. 1t has unique properties in its efficient counting geometry, deteetability and the lack of...

    In this paper we consider an elementary, and largely unexplored, combinatorial problem in low-dimensional topology. Consider a real 2-dimensional compact surface $S$, and fix a number of points $F$ on its boundary. We ask: how many configurations of disjoint arcs are there on $S$ whose boundary is $F$? We find that this enumerative problem, counting curves on surfaces, has a rich structure. For instance, we show that the curve counts obey an effective recursion, in the general framework of to...

    2016-01-01

    Interpreting renormalization group flows as solitons interpolating between different fixed points, we ask various questions that are normally asked in soliton physics but not in renormalization theory. Can one count RG flows? Are there different "topological sectors" for RG flows? What is the moduli space of an RG flow, and how does it compare to familiar moduli spaces of (supersymmetric) dowain walls? Analyzing these questions in a wide variety of contexts --- from counting RG walls to AdS/C...

  2. Neutron counting with cameras

    A research project is presented in which we aim at counting individual neutrons with CCD-like cameras. We explore theoretically a technique that allows us to use imaging detectors as counting detectors at lower counting rates, and transits smoothly to continuous imaging at higher counting rates. As such, the hope is to combine the good background rejection properties of standard neutron counting detectors with the absence of dead time of integrating neutron imaging cameras as well as their very good spatial resolution. Compared to Xray detection, the essence of thermal neutron detection is the nuclear conversion reaction. The released energies involved are of the order of a few MeV, while X-ray detection releases energies of the order of the photon energy, which is in the 10 KeV range. Thanks to advances in camera technology which have resulted in increased quantum efficiency, lower noise, as well as increased frame rate up to 100 fps for CMOS-type cameras, this more than 100-fold higher available detection energy implies that the individual neutron detection light signal can be significantly above the noise level, as such allowing for discrimination and individual counting, which is hard to achieve with X-rays. The time scale of CMOS-type cameras doesn't allow one to consider time-of-flight measurements, but kinetic experiments in the 10 ms range are possible. The theory is next confronted to the first experimental results. (authors)

    Diglycidyl ether of bisphenol A (DGEBA) epoxy resins belong to the most common causes of occupational allergic contact dermatitis. DGEBA has on rare occasions caused occupational asthma. Here we present a patient who first developed occupational allergic contact dermatitis (ACD) caused by a single accidental exposure to DGEBA. Then, on continued occupational exposure to DGEBA, the patient developed occupational asthma from DGEBA, in addition to ACD. A bronchial provocation test with DGEBA caused a 36% drop in the peak expiratory flow, reflecting a delayed type of occupational asthma. This bronchial provocation test caused a strong dermatitis of the exposed skin of the face, in accordance with airborne ACD from DGEBA.

    A controlled, blind study was conducted to define the initial inflammatory response and lung damage associated with the death of precardiac stages of Dirofilaria immitis in cats as compared to adult heartworm infections and normal cats. Three groups of six cats each were used: UU: uninfected untreated controls; PreS I: infected with 100 D. immitis L3 by subcutaneous injection and treated topically with selamectin 32 and 2 days pre-infection and once monthly for 8 months); IU: infected with 100 D. immitis L3 and left untreated. Peripheral blood, serum, bronchial lavage, and thoracic radiographic images were collected from all cats on Days 0, 70, 110, 168, and 240. CT images were acquired on Days 0, 110, and 240. Cats were euthanized, and necropsies were conducted on Day 240 to determine the presence of heartworms. Bronchial rings were collected for in vitro reactivity. Lung, heart, brain, kidney, and liver tissues were collected for histopathology. Results were compared for changes within each group. Pearson and Spearman correlations were performed for association between histologic, radiographic, serologic, hematologic and bronchoalveolar lavage (BAL) results. Infected cats treated with selamectin did not develop radiographically evident changes throughout the study, were heartworm antibody negative, and were free of adult heartworms and worm fragments at necropsy. Histologic lung scores and CT analysis were not significantly different between PreS I cats and UU controls. Subtle alveolar myofibrosis was noted in isolated areas of several PreS I cats and an eosinophilic BAL cytology was noted on Days 75 and 120. Bronchial ring reactivity was blunted in IU cats but was normal in PreS I and UU cats. The IU cats became antibody positive, and five cats developed adult heartworms. All cats with heartworms were antigen positive at one time point; but one cat was antibody positive, antigen negative, with viable adult females at necropsy. The CT revealed early involvement

    The retrospective study aimed to evaluate the diagnostic value of bronchial brushing and sputum using acid fast bacilli smear, mycobacterial culture and real-time PCR in detection of pediatric pulmonary tuberculosis, sensitivity and specificity of bronchial brushing and sputum examined by the three methods were calculated and compared to each other. Data showed there were no significant difference in sensitivity between bronchial brushing and matched sputum using each method. But the specificity of real-time PCR on bronchial brushing was lower than on sputum. Compared with bronchial brushing, sputum was better specimen in detection of pediatric pulmonary tuberculosis.

    In the article, a new method of diagnosing the extent of the tumor spread in the bronchial wall without involvement of the mucosa (a peripbronchial form of the growth) is described. The method consists of two components - angiography of bronchial arteries with subsequent injection of a staining material in the corresponding bronchial artery and bronchoscopy, by means of which staining of the mucous membrane of the bronchial tree is observed. In case of tumor infiltration of the bronchial wall staining was absent completely or partially. A clinical trial of the method indicated its high efficacy.

    It has been considered by modern medicine that bronchial asthma is a chronic airway allergic inflammation (AAI) which is the major factor that induces reversible airway ventilating disturbance and bronchial hyper-responsiveness (BHR) in asthmatic patients, as well as a correlation between the delayed-phase onset of asthma and AAI is more significant than immediate-phase onset of asthma in its pathogenesis. Anti-inflammatory therapy as a fundamental principle of treatment for bronchial asthma has been brought forward during the interval phase so that a large number of anti-AAI drugs to significantly enhance the curative effect such as inhalant corticoid, disodium cromoglycate, and leukotriene receptors antagonist, etc., has been rapidly developed. Additionally, traditional Chinese medicine (TCM) and integration of TCM and western medicine (WM) therapies, including acupuncture, are gradually taken into account by the medical circle as a characteristic in our country for treatment of bronchial asthma. It is worthy of being pointed out that the curative effect of acupuncture and moxibustion in treating asthma is evident, and that its therapeutic mechanism has to a certain extent, been found along with the recent deep-going acupunctural research.……

    Full Text Available Abstract Background Airway narrowing associated with chronic asthma results in the transmission of injurious compressive forces to the bronchial epithelium and promotes the release of pro-inflammatory mediators and the denudation of the bronchial epithelium. While the individual effects of compression or denudation are well characterized, there is no data to elucidate how these cells respond to the application of mechanical compression in the presence of a compromised epithelial layer. Methods Accordingly, differentiated normal human bronchial epithelial cells were exposed to one of four conditions: 1 unperturbed control cells, 2 single scrape wound only, 3 static compression (6 hours of 30 cmH2O, and 4 6 hours of static compression after a scrape wound. Following treatment, wound closure rate was recorded, media was assayed for mediator content and the cytoskeletal network was fluorescently labeled. Results We found that mechanical compression and scrape injury increase TGF-β2 and endothelin-1 secretion, while EGF content in the media is attenuated with both injury modes. The application of compression after a pre-existing scrape wound augmented these observations, and also decreased PGE2 media content. Compression stimulated depolymerization of the actin cytoskeleton and significantly attenuated wound healing. Closure rate was partially restored with the addition of exogenous PGE2, but not EGF. Conclusion Our results suggest that mechanical compression reduces the capacity of the bronchial epithelium to close wounds, and is, in part, mediated by PGE2 and a compromised cytoskeleton.

  13. Inhaled Mannitol as a Laryngeal and Bronchial Provocation Test.

    Timely diagnosis of vocal cord dysfunction (VCD), more recently termed "inducible laryngeal obstruction," is important because VCD is often misdiagnosed as asthma, resulting in delayed diagnosis and inappropriate treatment. Visualization of paradoxical vocal cord movement on laryngoscopy is the gold standard for diagnosis, but is limited by poor test sensitivity. Provocation tests may improve the diagnosis of VCD, but the diagnostic performance of current tests is less than ideal. Alternative provocation tests are required. This pilot study demonstrates the feasibility of using inhaled mannitol for concurrent investigation of laryngeal and bronchial hyperresponsiveness. Consecutive patients with suspected VCD seen at our institution's asthma clinic underwent flexible laryngoscopy at baseline and following mannitol challenge. VCD was diagnosed on laryngoscopy based on inspiratory adduction, or >50% expiratory adduction of the vocal cords. Bronchial hyperresponsiveness after mannitol challenge was also assessed. We evaluated the interrater agreement of postmannitol laryngoscopy between respiratory specialists and laryngologists. Fourteen patients with suspected VCD in the context of asthma evaluation were included in the study. Mannitol provocation demonstrated VCD in three of the seven patients with normal baseline laryngoscopy (42.9%). Only two patients had bronchial hyperresponsiveness. There was substantial interrater agreement between respiratory specialists and laryngologists, kappa = 0.696 (95% confidence interval: 0.324-1) (P = 0.006). Inhaled mannitol can be used to induce VCD. It is well tolerated and can evaluate laryngeal and bronchial hyperresponsiveness at the same setting. Copyright © 2017 The Voice Foundation.
