Introduction: The synergetic evaluation of the hyperglycemia and the white blood count as leukoglycemic index (LGI) joins a bigger number of adverse events during the internment in patients with ST Elevation Myocardial Infarction (STEMI). Objective: To evaluate the predictive value of the leukoglycemic index (LGI) in the appearing of in-hospital complications in ST-elevation myocardial infarction (STEMI). Method: Multicentral and historic cohort study, which included 1133 patients inserted in the Cuban Registry of Acute Myocardial Infarction, among January 2018 and June 2021. Patients were divided in quartiles and in groups according to the optimal cut-point calculated for the LGI. Results: Optimal cut-point of the ILG to predict complications was 1188.4 (sensibility 61.4%; specificity 57.3%; area under curve 0.609; p < 0.001). The appearing of in-hospital complications was significantly increased in the LGI’s quartiles; as well as in the two groups according to cut-point. The analysis of logistic regression revealed that the LGI was an independent predictor of in-hospital complications (OR [IC 95%] = 1.27 [1.11-1.46]; p = 0.001). When the LGI was associated to the multivariate model, its predictive capability was rose (area under curve 0.813; p < 0.001). Kaplan Meier’s curves showed significant differences among groups of patient (p = 0.030). Conclusions: The LGI is an independent predictor of appearing of in-hospital complications in STEMI. The addition of the LGI to a basal model of risk has a strong positive effect in the prediction of adverse prognosis in patients with STEMI. [ABSTRACT FROM AUTHOR]

Introducción: la enfermedad de Pompe (EP) o glucogenosis tipo II es una enfermedad autosómica recesiva causada por mutaciones en el gen GAA que codifica para la proteína alfa-1,4-glucosidasa. Su deficiencia lleva a un almacenamiento anormal de glucógeno en los lisosomas de varias células, a través de los diferentes tejidos, lo que causa un compromiso musculoesquelético predominante. Contenidos: los fenotipos de la enfermedad dependen de las variantes genéticas y de los niveles de la actividad enzimática residual. La enfermedad se presenta como EP de inicio infantil, EP de inicio tardío y EP intermedio, por lo que es de suma importancia su diagnóstico temprano, por medio de estudios moleculares como la secuenciación de Sanger y la secuenciación de nueva generación. Conclusiones: se ha demostrado, mediante diferentes estudios, que las variaciones genéticas pueden diferir entre etnias, y es importante su caracterización molecular para determinar el tratamiento más adecuado, de acuerdo con el estado del material inmunológico de reacción cruzada (CRIM).

El aborto enzootico ovino es una enfermedad causada por Chlamydia abortus. Es considerada una zoonosis y una de las principales causas de pérdidas económicas en estas explotaciones. Este trabajo se enfocó en utilizar el cultivo de leucocitos de animales sin signos de abortos y la detección de anticuerpos para determinar la posible presencia de C. abortus en explotaciones de traspatio. Se obtuvieron 42 muestras de sangre periférica de ovejas de diferentes poblaciones. La detección de Chlamydia abortus se realizó mediante la tinción de Giemsa y la técnica de PCR. La detección de anticuerpos anti-C. abortus se dio mediante una técnica de ELISA comercial. Los resultados mostraron 21 muestras positivas mediante la técnica de PCR, de las cuales solo 10 fueron positivas mediante la técnica de Giemsa, mientras que 22 sueros mostraron anticuerpos anti-C. abortus. En este estudio el 38,1 % de las muestras fueron positivas a la infección por C. abortus, como se confirmó mediante PCR y serología. En conclusión, los leucocitos de sangre periférica pueden ser útiles para detectar una infección por Chlamydia spp. en explotaciones sin historial de abortos, con lo que se puede conocer la prevalencia real del aborto enzootico ovino en México.

The populations of Baird's (Centronyx bairdii) and grasshopper (Ammodramus savannarum) sparrows are decreasing as a consequence of the loss of their natural habitat and the indiscriminate use of agrochemicals in farming areas bordering their breeding habitat. Although these two species have been studied from an ecological perspective, there is no research on the presence of abnormalities in their leukocyte and erythrocytes counts, both of them health biomarkers. The objective of this work was to determine the spontaneous rate of polychromatic erythrocytes (PCE), micronucleated erythrocytes (MNE), and nuclear buds (NBs), as well as the leucocyte differential and the heterophil/lymphocyte ratio (H:L), in order to establish the health status of these sparrow species that live in Cuchillas de la Zarca, Durango, Mexico. With this aim, we captured 20 organisms of each species with mist nets. We carried two blood smears per individual which we analysed under the microscope (100x). There were no statistically significant differences among species regarding the frequencies of the various biomarkers, which had similar values to those established for other healthy bird species. Therefore, there is no evidence of genomic instability, nor of genotoxic or cytotoxic effects. Likewise, we detected no alterations in the immune system, based on the leukocyte differential and the H:L ratio evaluation. This is the first study that establishes reference values for these biomarkers among these particular species of sparrows. [ABSTRACT FROM AUTHOR]

Objective: To quantify the production of Th1/Th2/Th17 cytokines induced by Ascaris lumbricoides antigens in peripheral blood mononuclear cells (PBMCs) using a multiplex technique. Methods: PBMCs were cultured from individuals with mild A. lumbricoides infection (n = 20) and uninfected individuals (n = 21) and stimulated with A. lumbricoides extract (ExtAscaris), a mix of anti-CD2/CD3/CD28 (CDmix) as a positive control, and only medium (negative control). Cytokines in the supernatants were measured using the BD™ Cytometric Bead Array Human Th1/Th2/Th17 kit, to identify IFN-γ, TNF, IL-10, IL-6, IL-4, IL-2, and IL-17A. Readings were taken on a spectral cytometer (Northern Lights, Cytek, USA), and analysis was performed using R software with packages "tidyverse," "beadplexr," "flowCore," and "arsenal." Cytokine concentrations were calculated using a 5-parameter logistic curve. The t-test was used to compare cases and controls, and statistical significance was set at p < 0.05. The study was approved by the Ethics Committee of the University of Cartagena and the participants provided informed consent. This study was financially supported by the Colombian Sistema General de Regalías under the BPIN2020000100405 - BPIN2020000100364. Results: Efficient fluorescence intensity extraction for each cytokine was achieved using detection channel R8 and the "mclust" clustering model (Figure 1). No significant differences were found in the levels of the seven cytokines between cases and controls (Figure 2). Although the IFN-γ response to ExtAscaris was higher in cases than in controls (252.5 ng/mL vs. 173.1 ng/mL), the difference was not significant. IL-17A (detection limit: 18.9 pg/mL) was more detectable in cases than controls (5 cases, 23% vs. 2 controls, 9.5%). IL-4 was only detected in the supernatants from CDmix-stimulated cultures but not with the Ascaris extract (Figure 2). Conclusions: The multiplex technique using spectral flow cytometry combined with open-source software analysis proved applicable for quantifying cytokines induced by A. lumbricoides antigens in PBMCs. However, a more sensitive method is needed to evaluate IL-4 response in the context of ascariasis. The results did not reveal significant differences in cytokine production between cases and controls for the evaluated stimuli. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the effect of astaxanthin on the hematological, biochemical and somatic response of Nile tilapia (Oreochromis niloticus) orally administered in the feed for a period of 60 days. For the study, 105 tilapia (n=35) from the same spawn were used, constituting the following treatments: Control = animals (not treated with astaxanthin); T100 and T200 = fish treated with 100 and 200 mg of astaxanthin/kg of feed, respectively. There were no hematological alterations in red blood cells counts, hematocrit, hemoglobin, MCV and MCHC. In addition, astaxanthin-fed tilapia presented a better thrombocyte and leukocyte responses with a marked decrease in the number of thrombocytes, lymphocytes and neutrophils. Among treatments, there were no changes in serum levels of total protein, albumin, globulins, aspartate aminotransferase and alkaline phosphate. Treatment with astaxanthin resulted in a decrease in triglyceride and glucose levels, as well as increase in hepatosomatic indices. The results of hematological and biochemical analyzes of tilapias demonstrated the clinical safety of this carotenoid, not causing harmful effects to the health of fish. Therefore, the antioxidant activity of this compound in tilapias resulted in an improvement in the leukocyte profile and contributed to hypolipidemic effects at the dose of 200mg of astaxanthin/kg of feed.

Se evidencio en pacientes con Covid-19 que no sobrevivieron un recuento de células TCD8 de 98,89 mientras que pacientes sobrevivientes fue de 203,98; en los pacientes no sobrevivientes se evidenciaron niveles elevados de IL-6, 10 veces superiores a los que sobrevivieron. Se concluye que en pacientes con Covid-19 los niveles de IL-6 (>20 pg/mL), así como el recuento de TCD8 (63 pg/dL) se pueden utilizar como predictor de la gravedad del dengue

Differential counting and blood cell morphometry in the lizards Ameivula ocellifera (Squamata: Teiidae) and Tropidurus hispidus (Squamata: Tropiduridae) from the Brazilian semiarid region, with analysis of the effects by hemoparasites. The lizards Ameivula ocellifera and Tropidurus hispidus are sympatric species in the Brazilian semiarid region. Despite being considered in-teresting models for ecological studies, little is known about basic aspects of their biology, such as hematological parameters. Thus, the objective of this work was to perform the differential count of leukocytes and describe the morphometry of erythrocytes and leukocytes in these two species of lizards, with emphasis on hemoparasitism by intracellular protozoa. For this, 30 specimens (15 A. ocellifera and 15 T. hispidus) were used for analysis. After making the slides, a differential count of 100 leukocytes per slide was performed. In addition, 20 erythrocytes and 15 leukocytes were photographed per slide for morphometric analysis. The measurements wrere measured for the parameters area, perimeter, maximum and minimum axes, with the ellipse formulas used for area and perimeter. Interspecific and intraspecific differences (parasitized and non-parasitized lizards) were tested for erythrocyte morphometric parameters, erythrocyte nucleus and leukocytes. The differential count showed that heterophiles were the predominant cell type for both species of lizards, while basophils were the least abundant for A. ocellifera and eosinophils for T. hispidus. As for leukocyte measurements, only the monocyte differed significantly between species, greater in A. ocellifera, and intraspecifically only for the minimum axis parameter, greater in parasitized T. hispidus. Erythrocytes differed between species in terms of cell and nucleus size, being higher in T. hispidus. Among the hemoparasites, found only in T. hispidus, Plasmodium sp. caused more discrete changes in the erythrocyte, while Hepatozoon sp. caused marked macrocytosis and hypochromia in these cells. In general, there does not seem to be a relationship between the differential leukocyte count and hemoparasitism. [ABSTRACT FROM AUTHOR]

Objectives. to assess the anti-inflammatory effect of the flavonoid fraction of Lepechinia meyenii (Walp.) Epling on leukocytes of patients with rheumatoid arthritis (RA). Materials and Methods. Plants of the species Lepechinia meyenii (Walp.) Epling were collected and then different flavonoid fractions were extracted by column and thin layer chromatography. The superoxide anion production was evaluated by means of the reduction of nitroblue tetrazolium assay technique in neutrophils obtained from the blood of patients with RA, divided into three groups: negative control, which consisted of neutrophils (5x105 cells); positive control, made up of PMA (phorbol myristate acetate)-activated neutrophils (150 ng/mL), and the treatments, comprised of neutrophils activated and treated with different concentrations of the flavonoid fraction LM8 (60, 120, and 180 ug/mL). The expression of proinflammatory genes was studied by RTqPCR in mononuclear leukocytes obtained from patients with RA, divided into three groups: negative control, which consisted of mononuclear leukocytes (5x105 cells); positive control, made up of phytohaemagglutinin (PHA) (150 ug/ml)-activated mononuclear leukocytes, and the treatment, comprised of mononuclear leukocytes activated and treated with the flavonoid fraction LM8 (120 ug/mL). Results. Several flavonoid fractions were purified, with fraction LM8 showing the best immunomodulating effect. Said fraction diminished the superoxide anion production dependent on concentration. On the other hand, it diminished the expression of TNFα, IL8, and IL17 in mononuclear leukocytes. Conclusions. These results are encouraging in terms of the immunomodulating effect of this Peruvian medicinal plant and justify the continuation of their study for a potential clinical application.

Con el objetivo de establecer los límites de referencia de analitos hematológicos de cabras adultas de razas productoras de leche clínicamente sanas, sujetas al manejo y a las características de los sistemas de producción intensiva del Altiplano Mexicano, se recolectaron y analizaron muestras de sangre de cabras de 2 o más años de edad en diferentes etapas de producción. Con los resultados se obtuvieron los límites de referencia para hematocrito, cuenta de eritrocitos, volumen globular medio (VGM), plaquetas, sólidos totales, fibrinógeno, cuenta de leucocitos, neutrófilos segmentados, neutrófilos en banda, linfocitos, monocitos, eosinófilos y basófilos. Las medias obtenidas para cada analito fueron: hematocrito (0,22-0,36 L/L), cuenta de eritrocitos (9,07-18,47 x1012/L), volumen globular medio (VGM) (14,44-27,91), plaquetas (229-3 1 63 x109/L), solidos totales (65,64-84,64 g/L), fibrinógeno (0-6 g/L), cuenta de leucocitos (3,75-11,47 x109/L), neutrófilos segmentados (0,95-4,98 x109/L), neutrófilos en banda (0-0,16 x109/L), linfocitos (1,76-6,44 x109/L), monocitos (0-0,65 x109/L), eosinófilos (0-1,36 x109/L) y basófilos (0 - 0,37 x109/L). Estos valores se compararon con los obtenidos en otros estudios similares, y se encontraron algunas diferencias mayoritariamente en los valores obtenidos para hematocrito, eritrocitos, VGM, plaquetas, leucocitos y linfocitos, lo cual se debe a las diferencias en condiciones medioambientales y de alimientación entre los estudios.

Introducción: La enfermedad de Gaucher es un trastorno metabólico por deficiencia o ausencia de enzimaβ-Glucosidasa Ácida. El diagnóstico se sospecha clínicamente, pero requiere confirmación mediante medición, en leucocitos (estándar de oro) o en sangre seca sobre papel de filtro, de la actividad de la enzimaβ-Glucosidasa Ácida. Objetivo: Evaluar la validez de la medición de la actividad de la enzima β-Glucosidasa Ácida en sangre seca en papel de filtro, comparada con el estándar de oro, para el diagnóstico de enfermedad de Gaucher en pacientes con sospecha clínica. Metodología: Se hizo una revisión sistemática de literatura. Se construyó y validó una pregunta PICO. Se usó una estrategia de búsqueda genérica con base en los términos clave (Gaucher Disease y Dried Blood Spot Analysis). Dos evaluadores independientes revisaron, evaluaron la calidad y extrajeron la información de los artículos. Resultados: Descartando los duplicados, se obtuvieron 47 artículos. Se evaluaron los textos completos de cuatro, y tres de ellos fueron excluidos al aplicar criterios de inclusión y exclusión. El artículo incluido tuvo una calidad excelente y mostró que la actividad enzimática de la glucocerebrosidasa en sangre seca tuvo sensibilidad de 82.3% y especificidad de 94.0% con un punto de corte de 0.0-2.75 y sensibilidad de 88.2% y especificidad de 88.5% con un punto de corte de 0.0-4.4. Conclusiones: La medición enzimática de la β-glucosidasa ácida en sangre seca es una excelente prueba para diagnóstico inicial de enfermedad de Gaucher. Sin embargo, no es una prueba concluyente.

To evaluate the edema volume and leukocyte, platelet, and fibrinogen count of peripheral burn in an animal model. The back left leg of Rattus norvegicus (experimental group) was placed in water at 60 °C for 60 seconds or at room temperature (control group). An analysis was carried out before and after the induced burn (at 4, 8, 12, and 24 h). The edema volume was determined by an orthogonal photo, the leukocyte and platelet counts were determined using automated equipment, and the fibrinogen count was determined using the gravimetric method. The maximum value of the edema was recorded at 4 h and leukocytes at 24 h. The platelet count did not vary at different post-edema time intervals. The fibrinogen level increased at 4 h and 24 h. In this animal model we induced systemic inflammation characterized by leukocytosis and elevated fibrinogen levels, combined with edema located at the induction area.

Introduction: The leuko-glycaemic index has been proposed as a prognostic marker of death in patients with acute myocardial infarction, but there is uncertainty surrounding its prognostic value to predict one-year mortality. Objectives: The aim of this study was to determine the prognostic value of leukoglycaemic index for one-year mortality in Cuban patients with ST-segment elevation myocardial infarction. Method: The data were obtained from the medical records and all cause one-year deaths was the primary endpoint. The leuko-glycaemic index was calculated from measurements at admission. The patients were divided into leuko-glycaemic index tertiles to be evaluated. Receiver operating characteristics and Kaplan-Meier survival curves were performed. Cox regression model was used for all multivariable analysis. Results: Three hundred and forty-four patients were assessed (median age, 68 years; 65.7% males; 25.6% diabetic). The mortality rate was 25.6%, being significantly higher in the upper tertile (55.7%, p<0.0001). The deceased patients presented a median of leuko-glycaemic index significantly higher than the survivors (2.18 and 1.34 respectively, p<0.0001). The area under the curve for leuko-glycaemic index was 0.715 and its cut-off value was 2.2. Any leuko-glycaemic index value higher than 2.2 was associated with significantly lower survival (177 vs. 309 days, p<0.0001) and it was an independent predictor of mortality (HR=3.56, CI 95%, 2.09-6.07, p<0.0001). Conclusions: The leuko-glycaemic index is a good predictor for all cause one-year mortality in patients with ST-segment elevation myocardial infarction. [ABSTRACT FROM AUTHOR]

Selenium decreases cellular damage caused by oxidative stress and improves the organism physiological response. Leukocytes were evaluated during embryonic development in ewes with consumption of organic selenium. A total of 27 local ewes at the municipality of San Andrés Chiautla, Mexico State, with an average age of 2.5 years, were randomly assigned in two groups, 11 in control group (without Selenium, S-Se) and 16 with oral selenium (C-Se; selenium-enriched yeast) addition at dose of 0.3 ppm, for a period of seven days before Artificial Insemination (AI) consuming a diet based on alfalfa and corn stubble. White cell differential counting was performed on blood smears. Samples were taken before, during and after selenium treatment. Data were analyzed by mixed model, showing significant differences by treatment and time (p ≤ 0.05) in neutrophils; day 9 of embryonic development (5.91 ± 0.89 y 2.11 ± 0.46; S-Se y C-Se, respectively) and basophils amount was at day -3 (1.85 ± 0.31 y 1.05 ± 0.23). Regarding lymphocytes and eosinophils, they showed a difference in time (p ≤ 0.05) but not by treatment (p ≥ 0.05). It is concluded that selenium decreases the number of neutrophils and basophils; after blastocyst formation and four days after starting organic selenium treatment. [ABSTRACT FROM AUTHOR]

The effect of adding Agaricus blazei to the diet of broilers on immunity, serum parameters, and antioxidant activity was evaluated. A total of 840 1-day-old chicks were used, distributed among five levels of a completely randomized design (0.0, 0.05, 0.10, 0.15, and 0.20% A. blazei), with six replications and 28 birds per experimental unit. The weights of the thymus, spleen and cloacal bursa were not influenced (P > 0.05). Leukocytes, macrophages and nitric oxide were unaffected (P > 0.05), but at each supplementation level compared with the control, differences appeared in the percentages of eosinophils and macrophages (P < 0.05) at inclusion levels of 0.10, 0.15 and 0.20%. At 28 days, the antibody titer against Newcastle disease showed a quadratic response (P < 0.05) with supplementation, and from the estimated level of 0.08% the production of antibodies was stimulated; however, the same behavior was not observed (P > 0.05) at 42 days. Hypocholesterolemic effect was demonstrated (P < 0.05), but the serum triglyceride concentration was not affected (P > 0.05). The antioxidant activity of mushroom showed a positive linear effect (P < 0.05) on DPPH capture on day zero of meat cooling. The inclusion of A. blazei in the diet of broilers provided an immunostimulatory activity and hypocholesterolemic effect. Residual compounds with antioxidant activity were present in the meat, which may promote tissue protection of the animal in vivo, making possible the use of A. blazei as a natural additive.

ABSTRACT Euphorbia tirucalli (L.), commonly known as aveloz, has been indiscriminately used in popular medicine to treat various illnesses. However, some components can have devastating consequences. Injury to a cell's genetic material can cause mutations, cancer, and cell death. Our main goal in this work was to evaluate the genotoxic and cytotoxic effects of E. tirucalli extract on human leukocytes. For this purpose, we performed a phytochemical analysis to evaluate the plant's components. In the second step, we treated cultured human leukocytes with different concentrations of the dry extract of the plant and then evaluated the oxidative and genotoxic profiles of these leukocytes. We found that at 1% and 10% concentrations, the aveloz extract acted as a genotoxic agent that could damage DNA and increase oxidative damage. We conclude that despite its popular use, aveloz can act as a genotoxic agent, especially when it contains phorbol ester. Aveloz's indiscriminate use might actually promote tumors and therefore carry a considerable genetic risk for its users.

In therapy, nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used to treat mild conditions and severe musculoskeletal disorders. However, some effects may occur due to their use, such as agranulocytosis, leukopenia and aplastic anemia. Objectives: to evaluate the effect of some NSAIDs on leukocyte production; to evaluate possible modification of the granules of neutrophils and to compare the total leukocyte count, by using manual and automated methods. 42 samples of whole blood of female rats, Wistar race, were analyzed in this experiment. The animals ingested solutions of diclofenac (DC), dipyrone (DP) and naproxen (NX), in two concentrations: the therapeutic plasma and another ten times more concentrated, for 5 days. We performed differential counts on stained smear and leukocytes were counted using manual methods with the Neubauer counting chamber and automated method (Coulter T-890). The comparison between the methods presented no significant differences in any analyzed group. Regarding to the overall number of leukocytes, no significant changes between the groups were observed. Regarding to the differential count we observed a significant increase in the number of atypical lymphocytes found in the group treated with diluted DP. This study demonstrated that dipyrone: 1) served as a toxic agent due to lymphocyte activation and the large number of neutrophils with nuclear pyknosis; 2) the Coulter T-890 can be used for total leukocyte count of animals; 3 ) other anti-inflammatory drugs studied did not cause abnormalities.

Los guajolotes criollos en el medio rural han tenido un papel de suma importancia ya que han aportado a la población humana proteínas de alta calidad biológica (carne y huevo) por lo general en condiciones adversas. La presente investigación tiene como objetivo describir el perfil hematológico del guajolote criollo de traspatio de la región de Tecamachalco, Puebla. Se seleccionaron y adquirieron 23 guajolotes criollos (GC), que se mantuvieron en confinamiento durante un mes alimentándose con maíz molido y alfalfa, similar al lugar de origen. Para el estudio hematológico se tomó una muestra de dos ml de sangre del ala. Se colocó en un tubo vial con anticoagulante EDTA rotulándose para su identificación. Se realizaron las siguientes determinaciones: Hematocrito (método del Micro hematocrito con tubos capilares, centrifugados a 12.000 r.p.m. durante 5 minutos), Hemoglobina (método de Drabkin), Glóbulos blancos (Neubauer) y Formula leucocitaria (recuento diferencial en frotis según Giemsa). Los resultados obtenidos fueron los siguientes: para hematocrito, proteínas plasmáticas, leucocitos totales, linfocitos, heterófilos, eosinòfilos, basófilos y monocitos, 49.39%, 5.56 g/dl, 22.55x 103/ul, 50.48%,35.35%, 11.57%, 1.65% y 5.87%, respectivamente. Los valores de referencia son: 49.39%, 5.56g/dl, 20 x 103/ul, 50%, 43%, 19%, 3% y 9%, por lo que se considera mínima la diferencia entre lo obtenido y los rangos referenciales. Esta información hematológica de los GCM en las condiciones descritas es la base para futuras investigaciones sobre esta especie animal, en particular para los estudios de resistencia a enfermedades y otros factores ambientales.

A ingestão de líquidos isotônicos (carboidratos e eletrólitos), durante as marchas, pode melhorar a reposição hídrica e o desempenho nas atividades militares (Pitaluga, 2001). Desta forma, o objetivo deste estudo foi verificar o efeito de uma marcha militar de 16 km sobre o índice de desidratação (Inddes), índices hematológicos, contagem de leucócitos e densidade de urina, segundo diferentes tipos de repositores hídricos. Participaram do estudo 42 militares do Exército Brasileiro, do 1º Esquadrão de Cavalaria Pára-quedista, na cidade do Rio de Janeiro, do sexo masculino, idade 22,6 ± 2,34 anos, massa corporal 72,99 ± 7,70 kg e peso transportado (material militar) 27,04 ± 2,11 kg. A amostra foi dividida, de forma aleatória, em quatro grupos, conforme o tipo de repositor utilizado (1 litro por indivíduo): água mineral (Gp 1); sem re hidratação (Gp 2); soro Babydrax (Gp 3); e Gatorade (Gp 4). Duas horas antes da marcha, foi realizada hidratação controlada de 600 ml de água. A marcha foi realizada das 11:30h às 15:30 h, com temperatura média de 16 oC e umidade relativa do ar de 79%. Foram realizadas três paradas de 10 minutos, a cada quatro km. O consumo do repositor foi controlado nas três paradas, devendo ser totalmente consumido até a última. Foram medidas, antes (A) e após (D) a marcha, a massa corporal (Pes), para avaliação do Inddes (diferença percentual entre a massa pré e pós-marcha), densidade de urina (DensU), índices hematológicos (porcentagem do hematócrito-Hm e contagem de hemoglobina Hb) e contagem de leucócitos (Leuc). Foi caracterizada a normalidade pelo teste de Kolmogorov-Smirnov.Utilizou-se o teste estatísticoANOVA one way para verificar a diferença entre as médias dos grupos em cada indicador. Entre todos os índices, DensU (F = 1,981, para p = 0,07), Hm (F = 0,48, para p = 0,86), Hb (F = 0,44, para p = 0,88) e Inddes (F = 5,175 para p = 0,004), apenas o Inddes apresentou diferença significativa entre os grupos. Utilizou-se o teste post hoc de Tukey para apontar os grupos distintos, indicando que a diferença foi entre os Gp 2 e 4, comvalores sugestivos à desidratação (Inddes > 3%) no Gp 2 e menores perdas no Gp 4. Conclui-se que a abstinência de líquidos, em atividade de marcha, pode levar à desidratação (Gp 2) e, apesar de não serem significativas, as diferenças nos Inddes dos Gp 1 e Gp 3 sugerem a possibilidade de alterações mais relevantes em distâncias maiores ou em condições climáticas menos favoráveis, parecendo ser interessante o consumo de bebida isotônica nestas atividades. Provavelmente, o não fornecimento de repositores estabelecesse efeito negativo no prosseguimento de uma operação militar, fruto da desidratação.

Resumo: A indoleamina 2,3-dioxigenase (IDO) é uma enzima que cataboliza o aminoácido triptofano, levando à inibição da proliferação de linfócitos T, seja pela exaustão desse aminoácido no ambiente, ou pela indução via catabólitos induzindo-os a apoptose. Em mamíferos, esta enzima atua em diversas condições do organismo como a gestação, infecções, inflamações crônicas, transplantes e tumores, atuando na regulação imunológica. Estudos recentes identificaram a presença de moléculas homólogas a IDO em espécies filogeneticamente inferiores, cuja função parece estar restrita ao metabolismo do triptofano como fonte de energia. Este estudo teve por objetivo averiguar a expressão da IDO em células sanguíneas e órgãos hematopoiéticos de truta arco-íris pela imuno-histoquímica, buscando evidências de que a mesma poderia, nesta espécie, estar relacionada ao sistema imune. A expressão de IDO foi observada nos órgãos hematopoiéticos estudados incluindo o rim cefálico que apresentou marcação em células interrenais e leucócitos; baço, na qual a marcação restringiu à alguns leucócitos; no fígado a marcação ficou limitada à apenas algumas células dentro dos vasos sanguíneos e nas extensões sanguíneas pode-se visualizar a marcação de alguns leucócitos como os monócitos, linfócitos e neutrófilos. A predominância da marcação da IDO nesses tecidos pode constituir uma evidência de que a IDO identificada na O. mykiss esteja relacionada ao sistema imunológico nessa espécie.

BackgroundSpontaneous bacterial peritonitis is defined as an ascetic fluid infection without an evident intra-abdominal surgically treatable source. Spontaneous bacterial peritonitis is one of the severe complications in patients with cirrhosis and ascites. Without early antibiotic treatment, this complication is associated with high mortality rate; therefore, early diagnosis and treatment of spontaneous bacterial peritonitis is necessary for survival. Leukocyte esterase reagent can rapidly diagnose the spontaneous bacterial peritonitis.ObjectiveThis study aimed to find out the diagnostic accuracy of leukocyte esterase dipstick test for the diagnosis of spontaneous bacterial peritonitis.MethodsA single centered hospital-based cross-sectional study was conducted during July 2013 to August 2014 on children with cirrhotic liver disease and ascites who were admitted in the Department of Pediatric Gastroenterology in Nemazee Hospital affiliated to Shiraz University of Medical Sciences (Iran). All patients underwent abdominal paracentesis, and the ascitic fluid was processed for cell count, leukocyte esterase reagent strip test (Combiscreen SL10) and culture. Spontaneous bacterial peritonitis was defined as having a polymorphonuclear count (PMN ≥250/m3) in ascitic fluid. Sensitivity, specificity, positive predictive value and negative predictive value of leukocyte esterase test were calculated according to the formula.ResultsTotally, 150 ascitic fluid sample of cirrhotic male patients (53.2%) and their mean age (4.33±1.88 years) were analyzed. Biliary atresia (n=44, 29.4%) and idiopathic neonatal hepatitis (n=29, 19.3%) were the most frequent etiology of cirrhosis. Also, abdominal pain (68.6%) and distension (64%) were the most common presenting complaint. Of all cases, 41patients (27.35%) were diagnosed to have spontaneous bacterial peritonitis (PMN ≥250/mm3). Sensitivity and specificity of leukocyte esterase reagent test according to PMNs ≥250mm3 were 87.80% and 91.74%, also on ascitic fluid culture results were 88.23% and 77.44%. Positive predictive value and negative predictive value of this test in PMNs ≥250mm3 were 80% and 95.23% and in cases with positive culture 33.33% and 98.09% were obtained, respectively. Efficiency of leukocyte esterase reagent test in diagnosing spontaneous bacterial peritonitis, according to PMNs ≥250mm3 and culture results were 90.66% and 78.66%.ConclusionThe leukocyte esterase strip test may be used as rapid test for diagnosis of spontaneous bacterial peritonitis due to its high diagnostic validity.

Estudos têm evidenciado alterações na resposta do sistema imune provocada pelo exercício físico de forma aguda, gerando um desvio do estado da homeostase orgânica. Dentre estas modificações da homeostasia, destacamos o aumento do número de leucócitos, principalmente dos neutrófilos segmentados (pseudoneutrofilia). O objetivo deste estudo foi verificar as alterações do número de neutrófilos de militares após realização de um teste de VO2máx (teste de Cooper). A amostra foi composta por 16 militares do sexo masculino, com idade entre 18 e 27 anos, residentes em Santo Ângelo, RS. Foram mensurados: estatura (m), massa corporal (kg), VO2máx (ml.kg-1.min-1), percentual de gordura (%G). Para a verificação das alterações dos neutrófilos através do exercício físico foi utilizado o teste de Cooper (teste dos 12 minutos). Para isto foi coletado sangue, três minutos antes e depois do teste. Para a análise dos dados utilizou-se o teste “t” de Student para amostras dependentes. Os resultados mostraram um aumento significativo no número de leucócitos entre o pré-teste (9518,75/mm³ ± 1978,96) e o pós-teste (13050,00/mm³ ± 3685,65). Já os neutrófilos segmentados apresentaram diferença significativa entre as médias (pré 6413,88 ± 1980,68 e pós 8859,13 ± 2798,76) mostrando ser o teste realizado o responsável pelo aumento, ocasionando uma pseudoneutrofilia. Com os resultados apresentados podemos concluir que a realização de um teste de VO2máx provoca uma pseudoneutrofilia, demonstrando o grande efeito da sobrecarga fisiológica na musculatura, provocado pelo exercício físico de grande intensidade e pequena duração, gerando uma imunodepressão no indivíduo. ABSTRACT Variation of neutrophil numbers in militaries after a VO2max test Some studies have evidenced alterations in the reply of the immune system provoked by the physical exercise of acute form, generating a shunting line of the state of the organic homeostasis. Between the modifications of the homeostasis, provoked by the physical stresses, we can detach the increase of numbers of leukocytes, mainly of the segmented neutrophil (pseudoneutrophilic). Therefore, the present study had as aim to verify the alterations of the number of neutrophil of military after the realization of the test VO2máx (test of Cooper). This research is of cause-effect with experimental delineation. The sample was composed for 16 military of the masculine sex, with age between 18 and 27 years, residents in Santo Ângelo, RS. Had been measured: stature (m), corporal mass (kg), VO2máx (ml.kg-1.min-1), percentage of fat (%G). For the verification of the alterations of the neutrophil through the physical exercise, was been used the test of Cooper (test of the 12 minutes). For this was collected blood, three minutes before and after the test. For the analysis of the data was used the “t” test of Student for dependent samples. The results had shown a significant increase in the number of leukocytes between the daily pay-test (9518,75/mm ³ ±1978,96) and the after-test (13050,00/mm ³ ±3685,65).Already the segmented neutrophil had presented a significant difference between the averages (daily pay 6413,88±1980,68 and after 8859,13±2798,76) having shown to be the test carried through responsible for the increase, causing pseudoneutrophilic. For the presented results we can conclude that the realization of a of VO2máx provokes a pseudoneutrophilic, demonstrating the great effect of the physiological overload in the musculature, provoked by the physical exercise of great intensity and small duration, generating a immune depression in the individual.

A utilização de bactérias do ácido láctico (LAB) como uma alternativa ao uso de antimicrobianos tem sido proposta para o controle da mastite bovina. No entanto, antes dessas aplicações, o efeito in vivo das LAB sobre a glândula deve ser cuidadosamente avaliado. O objetivo deste estudo foi determinar se a infusão intramamária de Weissella confusa e seus metabólitos em vacas afeta a contagem de células somáticas (CCS) e a contagem diferencial de leucócitos no leite. Vinte e quatro tetos de seis vacas Hartón del Valle foram selecionados para a pesquisa. Uma alíquota de 5mL de uma solução aquosa de células de W. confusa (W) (concentração 109u.f.c. mL-1), 5mL de células de W. confusa com seus metabólitos (W + W10b) ou 5mL de metabólitos (W10b) foi aplicada ao acaso em três tetos de cada vaca. O teto restante em cada úbere representou a unidade experimental de controle (C). Nos dias 1, 2, 3, 5, 7, 9, 13 e 15 após infusão (PI), a CCS, o pH, a acidez titulável e a contagem diferencial de leucócitos no leite foram avaliadas. A aplicação das três substâncias biológicas produziu aumentos significativos na CCS, no pH e na contagem de neutrófilos polimorfonucleares. Não foram encontradas diferenças significativas entre W e W+W10b. O W10b mostrou a menor alteração sobre as variáveis avaliadas. Os resultados sugerem que a aplicação de W. confusa e seus metabólitos afeta a CCS e a contagem diferencial de leucócitos no leite.

Micotoxinas representam um vasto grupo de contaminantes químicos naturais originados a partir do metabolismo secundário de fungos filamentosos patogênicos. Elas são produzidas, principalmente, pelos gêneros Fusarium, Alternaria, Aspergillus e Penicillium, os quais podem contaminar grãos e cereais, como trigo, milho e soja. Conforme sua natureza e níveis de concentração, micotoxinas podem induzir efeitos tóxicos em animais de produção e humanos. Um estudo in vitro foi realizado para avaliar a susceptibilidade das células linfocitárias de frangos de corte a diferentes concentrações de ocratoxina A, deoxinivalenol e zearalenona. Cada micotoxina foi adicionada ao meio celular em diferentes concentrações (0,001; 0,01; 0,1 e 1μg/mL). A viabilidade celular e atividade de ecto-adenosina desaminase foram analisadas em 24, 48 e 72 horas através de ensaios colorimétricos. Para isso, foram utilizados 0,7x10(5) linfócitos/mL em meio RPMI 1640, suplementado com 10% de soro fetal bovino e 2,5 UI de penicilina/estreptomicina por mL, incubados em atmosfera de 5% de CO2 a 37 °C. Todos os experimentos foram realizados em triplicata e os resultados foram expressos como média e erro padrão da média. Os resultados obtidos demonstraram que tanto ocratoxina A como deoxinivalenol induziram proliferação linfocitária e baixa atividade enzimática in vitro (P0,05). Foi possível correlacionar os dados referentes à viabilidade celular e atividade de ecto-adenosina desaminase, sugerindo que, em concentrações mínimas, as micotoxinas testadas não estimularam a atividade da enzima, que possui ação pró-inflamatória e contribui para o processo de imunossupressão e, portanto, evitando um decréscimo na viabilidade celular. Este é o primeiro estudo feito com OCRA, DON e ZEA sobre linfócitos de frangos de corte em cultivos in vitro na avaliação desses parâmetros.

With the aim to establish the hematological analyte reference limits of clinically healthy adult goats of dairy producing breeds, subjected to the handling and characteristics of intensive production systems in the Mexican Plateau, the blood samples of 2-year old and older goats at different production stages were collected and analyzed. Reference limits (interval in brackets) for hematocrit (0.22-0.36 L/L), erythrocyte count (9.07-18.47 ×1012/L), mean cell volume (MCV) (14.44-27.91 fL), platelets (229-3163 ×109/L), total solids (65.64-84.64 g/L), fibrinogen (0-6 g/L), leukocyte count (3.75-11.47 ×109/L), segmented neutrophils (0.95-4.98 ×109/L), band neutrophils (0-0.16 ×109/L), lymphocytes (1.76-6.44 ×109/L), monocytes (0-0.65 ×109/L), eosinophils (0-1.36 ×109/L) and basophils (0-0.37 ×109/L) were obtained. These values were compared with similar study results. Differences were found mainly in the values for hematocrit, erythrocytes, MCV, platelets, total leukocytes, and lymphocytes; this is due to environmental and feeding differences between the studies.
