Yield response factor (Ky) and initial growth in black pepper in a tropical environment

Black pepper is widely produced in Brazil, though there are few studies related to its water requirements and the effects of water deficit (WD) applied under tropical conditions. The growth, sensitivity to WD, and first-year productivity of irrigated plants from the Bragantina cultivar were evaluated, employing an irrigation system with automatic management. The plants were cultivated in plastic pots installed in the field for 391 days using emitters with different flow rates (2.2 [T1], 3.3 [T2], 4.3 [T3], and 5.3 L h­1 [T4 ­ control]). Fresh weight of the leaves, stems, and shoots, and dry weight of the leaves, stem, roots, and shoots as well as the total dry weight of the plant, were evaluated. Productivity was determined by evaluating the grains and spikes from a single harvest. Yield results and the actual versus maximum evapotranspiration rate for the entire growing season was used for calculating the Ky coefficient. Despite 1,346 mm of rainfall, the irrigation system was activated 165 times, distributing a mean volume of 19.0 (T1), 28.5 (T2), 37.1 (T3), and 45.8 L per plant (control). All traits were negatively affected by the WD, and the Ky values obtained (from 1.72 to 2.96) indicate the high sensitivity of black pepper to WD. In general, the spikes produced with at least 81 % of the crop water demand were larger and more numerous than those subjected to inferior treatments. WD occurring during the flowering stage severely hampers the size, weight, and quality of the spikes and grains of black pepper.(AU)

Diagnosis of transmissible venereal tumors in bitches - platelet indices are a remarkable marker?

Background: Hematological analyses are seen as more preferred laboratory analyses in canine transmissible venereal tumor studies. There is no information about the availability of platelets and their indices in routine practice in canine transmissible venereal tumor cases. Taking this as a starting point, this study analyzed the usefulness of platelet indices in dogs with transmissible venereal tumor in clinical laboratory diagnosis as well as examined the relationship between white blood cells, red blood cells, platelets (PLT), main platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), and the ratio of main platelet volume to platelets (MPV/PLT). Materials, Methods & Results: In the study, a total of 42 bitches of various breeds were used. Nineteen healthy bitches were used as a control group, and the others 23 with cTVT as a study group. Metastasis was not observed in any of the bitches involved in the study. History, clinical findings, and cytological examinations were evaluated for the diagnosis of cTVT. In animals with hemorrhagic discharge and neoplastic lesions, a vaginal cytological examination was performed. Typical TVT cells with large nuclei and intracytoplasmic vacuoles were observed in the vaginal cytological examinations, and the diagnosis of TVT was made. Healthy bitches (19) and those with TVT (23) were 39.16 5.37 months and 47.61 5.14 months old, respectively. From all animals, 2 mL blood samples were collected from V. cephalica to evaluate PIs in the complete blood count (CBC). Collected blood samples were analyzed using an automated hematology analyzer. As a result of the analysis, WBC, RBC, HGB, HCT, MCV, MCHC, RDW, PLT, MPV, PDW, PCT, and MPV/PLT data were obtained. Mild leukocytosis, an increase in PLT, and a decrease in MCV and MPV/PLT were determined in the study group compared to the control group. Cut-off values in CBC of bitches with TVT were determined as WBC: 13.35 (sensitivity: 78%; specificity: 90%); MCV: 67 (sensitivity: 57%; specificity: 95%); PLT: 315.50 (sensitivity: 65%; specificity: 74%); and MPV/PLT: 0.028 (sensitivity: 78%; specificity: 58%). In CBC analyses, a strong negative correlation between PLT and MPV/PLT was detected in both groups. Discussion: Canine transmissible venereal tumors are common in both stray and pet dogs. It is naturally transferred from animal to animal during mating by live tumor cells. This tumor can commonly affect the external genitalia and internal organs in some cases. It generally has the look of cauliflower, and its surface is ulcerated, inflammatory, hemorrhagic, and infectious. More preferred laboratory analyses are complete blood count and blood chemistry analysis in cTVT for to evaluate the success of treatments. Platelet indices have been investigated in many diseases such as endotoxemia, chronic enteropathy, mammary tumor, parvoviral enteritis, septic peritonitis, lymphoma, pyometra, visceral leishmaniasis, and babesiosis in dogs. There is no information available for either diagnostic or prognostic use of the PIs in canine TVT cases. Ultimately, in light of the presented study's results, platelet indices, especially PLT and the MPV/PLT ratio, seem to be notable laboratory markers in terms of easy accessibility and low-cost assessment techniques in canine transmissible venereal tumor cases. New data, however, should be established by a thorough follow-up study using a larger sample size and addressing its usefulness as a diagnostic or prognostic marker in canine transmissible venereal tumors.

Diarrhea in cats infected with Cystoisospora spp. - evaluation of the neutrophil-to-lymphocyte ratio and monocyte-to-lymphocyte ratio

Background: Cystoisospora spp. is considered a potential pathogen to cause diarrhoea in cats, and the disease occurs clinically, especially in young, weak and immunocompromised cats. The present study aimed to evaluate the clinical utility and diagnostic roles of neutrophil-to-lymphocyte ratio (NLR) and monocyte-to-lymphocyte (MLR) ratios in diarrheal cats infected with Cystoisospora spp. Materials, Methods & Results: Twenty-five cats with diarrhea due to infection caused by Cystoisospora spp. and 15 healthy cats were included in this study. The anamnesis, clinical and laboratory findings of all cats were recorded. A clinical severity score was generated for diarrheal cats, which included activity, appetite, presence of vomit, and faecal consistency. Also, cats infected with Cystoisospora spp. were classified as systemic inflammatory response syndrome (SIRS) positive (+) and SIRS (-) group according to the presence of at least 3 of the SIRS criteria. The Cystoisospora spp. oocysts were diagnosed by direct smear and simple faecal flotation. Cats found positive for other parasitic and protozoal agents by faeces examination were excluded from the study. Complete blood counts (CBC) were performed with an automated blood cell counter for all cats. Blood smears were prepared (with May-Grunwald Giemsa) from samples, and the CBC results were confirmed microscopically (obj.100x). White blood cell (WBC), neutrophil, lymphocyte and monocyte counts were recorded directly from the CBC. The neutrophil-to-lymphocyte ratio was calculated as the ratio of the absolute neutrophil count to the absolute lymphocyte count. The monocyte-to-lymphocyte was calculated as the absolute monocyte count ratio to the absolute lymphocyte count. White blood cell (P = 0.015), neutrophil (P = 0.001), monocyte (P = 0.033), NLR (P = 0.000) and MLR (P = 0.042) of diarrheal cats infected with Cystoisospora spp. were significantly higher than in the healthy group. There was no significant difference between groups in the lymphocyte counts (P > 0.05). SIRS (+) group had statistically significantly higher WBC (P = 0.014), neutrophil counts (P = 0.000), NLR (P = 0.000) and MLR (P = 0.037) than the healthy group. Also, neutrophil counts and NLR of the SIRS (+) group were statistically significantly higher than the SIRS (-) group (P = 0.032; P = 0.001, respectively). However, there was no significant difference SIRS (+), SIRS (-), and healthy groups regarding lymphocyte and monocyte counts (P > 0.05). The clinical severity of the disease positively correlated with NLR and MLR. Also, the best cut-off value of NLR to predict SIRS was > 1.67, with 92.86% sensitivity and 84.62% specificity. MLR was not a useful predictor for SIRS. Discussion: NLR and MLR are parameters derived from complete blood count. In recent years, they have been used in human and veterinary medicine as a biomarker in the diagnosis, prognosis and treatment follow-up of various diseases and provide valuable information about inflammation. In cats, there are limited studies on NLR, and to our knowledge, there are no studies on MLR. The current study suggests that NLR and MLR may be used to determine the severity of the inflammatory condition in diarrheal cats infected with Cystoisospora spp., and NLR is a useful marker for predicting SIRS status in these cats. In addition, this study also will contribute to larger-scale studies in the future.

Hyperhomocysteinemia as an Independent Risk Factor for Coronary Heart Disease. Comparison with Conventional Risk Factors / Hiper-homocisteinemia como fator de risco independente para doença coronariana: comparação com fatores de risco convencionais

Abstract The present study was designed to evaluate the strength of association of raised plasma homocysteine concentration as a risk factor for coronary heart disease independent of conventional risk factor. It was a case control study conducted at Punjab Institute of Cardiology Lahore. A total of 210 subjects aged 25 to 60 years comprising of 105 newly admitted patients of CHD as cases and 105 age and sex matched healthy individuals with no history of CHD as control were recruited for the study. Fasting blood samples were obtained from cases and controls. Plasma homocysteine was analyzed by fluorescence polarization immunoassay (FPIA) method on automated immunoassay analyzer (Abbott IMX). Total cholesterol, triglyceride and HDL cholesterol were analyzed using calorimetric kit methods. The concentration of LDL cholesterol was calculated using Friedewald formula. The patients were also assessed for traditional risk factors such as age, sex, family history of CVD, hypertension, smoking and physical activity, and were compared with control subjects. The collected data was entered in SPSS version 24 for analysis and interpretation.The mean age in controls and experimental groups were 43.00± 8.42 years and 44.72± 8.59 years with statistically same distribution (p- value= 0.144). The mean plasma homocysteine for cases was 22.33± 9.22 µmol/L where as it was 12.59±3.73 µmol/L in control group. Highly significant difference was seen between the mean plasma level of homocysteine in cases and controls (p˂0.001).Simple logistic regression indicates a strong association of coronary heart disease with hyperhomocysteinemia (OR 7.45), which remained significantly associated with coronary heart disease by multivariate logistic regression (OR 7.10, 95%C1 3.12-12.83, p=0.000). The present study concludes that elevated levels of Plasma homocysteine is an independent risk factor for coronary heart disease independent of conventional risk factors and can be used as an indicator for predicting the future possibility for the onset of CVD.

Resumo O presente estudo foi desenhado para avaliar a força da associação da concentração elevada de homocisteína no plasma como um fator de risco para doença cardíaca coronária independente do fator de risco convencional. Foi um estudo de caso-controle realizado no Punjab Institute of Cardiology Lahore. Um total de 210 indivíduos com idade entre 25 e 60 anos, compreendendo 105 pacientes recém-admitidos de CHD como casos e 105 indivíduos saudáveis ​​pareados por idade e sexo sem histórico de CHD como controle, foi recrutado para o estudo. Amostras de sangue em jejum foram obtidas de casos e controles. A homocisteína plasmática foi analisada pelo método de imunoensaio de polarização de fluorescência (FPIA) em analisador de imunoensaio automatizado (Abbott IMX). Colesterol total, triglicerídeos e colesterol HDL foram analisados ​​usando métodos de kit calorimétrico. A concentração de colesterol LDL foi calculada pela fórmula de Friedewald. Os pacientes também foram avaliados para fatores de risco tradicionais, como idade, sexo, história familiar de DCV, hipertensão, tabagismo e atividade física, e foram comparados com indivíduos de controle. Os dados coletados foram inseridos no SPSS versão 24 para análise e interpretação. A média de idade nos grupos controles e experimentais foi de 43,00 ± 8,42 anos e 44,72 ± 8,59 anos com distribuição estatisticamente igual (p-valor = 0,144). A homocisteína plasmática média para os casos foi de 22,33 ± 9,22 µmol / L, enquanto no grupo controle foi de 12,59 ± 3,73 µmol / L. Diferença altamente significativa foi observada entre o nível plasmático médio de homocisteína em casos e controles (p ˂ 0,001). A regressão logística simples indica uma forte associação de doença cardíaca coronária com hiper-homocisteinemia (OR 7,45), que permaneceu significativamente associada com doença cardíaca coronária por multivariada regressão logística (OR 7,10, 95% C1 3,12-12,83, p = 0,000). O presente estudo conclui que níveis elevados de homocisteína plasmática são fator de risco independente para doença cardíaca coronária, independentemente dos fatores de risco convencionais, e pode ser usado como um indicador para prever a possibilidade futura de aparecimento de DCV.

Staphylococcal cassette chromosome mec elements from Staphylococcus intermedius group (SIG) isolates from dogs in a center for veterinary diagnostics in Brazil / Cassetes cromossômicos estafilocócicos mec de isolados do grupo Staphylococcus intermedius (GSI) de cães em um centro veterinário de diagnósticos no Brasil

Methicillin resistance in the Staphylococcus intermedius group (SIG) has emerged in small animal practice. Methicillin-resistant SIG (MRSIG) members have been implicated as causes of infections in both companion animals and humans. Staphylococcal cassette chromosome mec (SCCmec) elements carry the mecA/C genes, which encode for the transpeptidase PBP2a (PBP2’) responsible for β-lactam antibiotic resistance in staphylococci. This study examined the SCCmec types of MRSIG isolates from different clinical specimens of dogs that exhibited methicillin MIC ≥ 0.5 μg/mL by an automated identification and susceptibility system in a Center for Veterinary Diagnostics in São Paulo, Brazil. Susceptibility to methicillin was determined by broth microdilution testing, and Oxoid® M.I.C.Evaluator® strips. PBP2a production was detected using a latex agglutination assay. SCCmec typing was performed according to the International Working Group on the Classification of Staphylococcal Cassette Chromosome Elements (IWG-SCC) guidelines. SCCmec type II (2A), SCCmec type III (3A), composite SCC structures consisting of a class A mec gene complex in addition to multiple ccr gene complexes, and non-typable SCCmec elements were reported in these MRSIG isolates. SCCmec type variants differing from those so far acknowledged by IWG-SCC were found, indicating new rearrangements in the genetic context of mecA in these canine MRSIG isolates.

A resistência à meticilina no grupo Staphylococcus intermedius (GSI) tem aumentado na clínica de pequenos animais.

Nosso objetivo foi investigar os elementos SCCmec de GSIRM isolados de diferentes amostras clínicas de cães que exibiram CIM de meticilina ≥ 0,5 μg/mL por meio de um sistema automatizado em um Centro Veterinário de Diagnósticos em São Paulo, Brasil. A sensibilidade à meticilina foi determinada por meio do teste de microdiluição em caldo e fitas Oxoid® M.I.C.Evaluator®. A produção de PBP2a foi detectada usando um ensaio de aglutinação de látex. A tipagem dos elementos SCCmec foi realizada de acordo com as diretrizes do International Working Group on the Classification of Staphylococcal Cassette Chromosome Elements (IWG-SCC). SCCmec tipo II (2A), SCCmec tipo III (3A), SCC compostos de um complexo mec de classe A com múltiplos complexos ccr, e elementos SCCmec não tipáveis foram encontrados nesses isolados GSIRM. Variantes que diferem dos elementos SCCmec reconhecidos até o momento pelo IWG-SCC foram encontradas, indicando novos rearranjos no contexto genético de mecA nesses isolados GSIRM caninos.

Sensitivity to antifungals by Candida spp samples isolated from cases of chronic atrophic candidiasis (CAC) / Sensibilidade a antifúngicos por amostras de Candida spp isoladas de casos de candidíase atrófica crônica (CAC)

The treatment of choice for chronic atrophic candidiasis (CAC), also known as denture stomatitis, is topical antifungal therapy. This study aimed to isolate, identify, and assess the antifungal susceptibility of Candida species from mucosal sites in denture wearers with a diagnosis of CAC and determine the prevalence of associated variables. The sample consisted of 44 patients wearing complete or partial dentures who had a clinical diagnosis of CAC. Using sterile cotton swabs, specimens were collected from the oral mucosa of all patients and grown at 30ºC for 48 h in CHROMagar Candida, as a means of isolating and screening the species. The complementary identification of the species was performed using the VITEK 2 automated system (BioMérieux), as well as the determination of their susceptibility to antifungal agents. Data were analyzed using the chi-square test. STATA 13.1 was used for statistical analysis ( = 5%). Of 44 patients with CAC, 33 (75%) had lesions classified as Newton type II. Yeasts were isolated in 38 cases. The most prevalent species was Candida albicans. None of the isolates were resistant to the antifungals tested. Our findings suggest that current indications for antifungal agents are appropriate. Also, antifungal susceptibility testing and proper fungal identification can help dentists to determine the optimal course of treatment for CAC.(AU)

O tratamento de escolha para candidíase atrófica crônica (CAC), também conhecida como estomatite protética, é a terapia antifúngica tópica. Este estudo teve como objetivo isolar, identificar e avaliar a susceptibilidade antifúngica de espécies de Candida de locais mucosos em portadores de prótese com diagnóstico de CAC e determinar a prevalência de variáveis associadas. A amostra consistiu em 44 pacientes portadores de próteses completas ou parciais que tiveram um diagnóstico clínico de CAC. Usando swab estéril, foram coletados espécimes da mucosa oral de todos os pacientes e cultivados a 30ºC durante 48 h em CHROMagar Candida, como forma de isolamento e triagem das espécies. A identificação complementar das espécies foi realizada no sistema automatizado VITEK 2 (BioMérieux), bem como a determinação da susceptibilidade delas a agentes antifúngicos. Os dados foram analisados usando o teste do qui-quadrado. O STATA 13.1 foi utilizado para análise estatística ( = 5%). Dos 44 pacientes com CAC, 33 (75%) apresentaram lesões classificadas como Newton tipo II. As leveduras foram isoladas em 38 casos. A espécie mais prevalente foi Candida albicans. Nenhum dos isolados foi resistente aos antifúngicos testados. Nossas descobertas sugerem que as indicações atuais para os agentes antifúngicos são apropriadas. Além disso, testes de susceptibilidade antifúngicos e identificação fúngica adequada podem ajudar os dentistas a determinar o curso ótimo de tratamento para CAC.(AU)

Distraction index measurement on the dog's hip joint using a dedicated software / [Medição do índice de distração da anca do cão usando um software especial]

The aim of this study was to test the accuracy of a new automated computer software tool for the assessment of passive hip laxity. The hip laxity was estimated using the dedicated computer software by two blinded evaluators, one previously trained and one without specific training for distraction index measurement, in two independent sessions using 230 hip joints from 115 dogs that underwent screening for passive hip laxity using the distraction view. Previously, all of these radiographs were sent to PennHIP Analysis Center for an official distraction index record. The measurement repeatability of the two sessions was adequate for both evaluators. The reproducibility of the official distraction index measurement, mean distraction index±standard deviation 0.44±0.15, was adequate (P>0.05) for the trained evaluator, 0.44±0.15, and non-adequate (P<0.05), for the non-trained evaluator 0.47±0.17. The distraction index measurement tool proposed can be used with confidence for hip laxity evaluation by trained evaluators, as it provided good repeatability and reproducibility of official reports. The simplicity of the process described leads to a less time-consuming and more affordable procedure.(AU)

O objetivo deste estudo foi testar a viabilidade de uma nova ferramenta de software informático para avaliação da lassitude articular passiva da articulação coxofemoral. A lassitude articular da articulação coxofemoral foi estimada usando-se um programa informático especial, desenvolvido para o efeito, por dois avaliadores, um com treino prévio e outro não treinado, na medição do índice de distração, em duas sessões independentes, utilizando-se 230 articulações coxofemorais de 115 cães, as quais efetuaram o rastreio de displasia coxofemoral realizando a projeção de distração da articulação coxofemoral. Previamente, todas as radiografias foram enviadas para o PennHIP Analysis Center, para se obter uma medida oficial do índice de distração. A repetibilidade das medições das duas sessões foi adequada para ambos os avaliadores. A reprodutibilidade do índice de distração oficial, média±desvio-padrão 0,44±0,15, foi adequada (P>0,05) para o avaliador treinado, 0,44±0,15, e não adequada (P>0,05) para o avaliador não treinado, 0,47±0,17. A ferramenta de medição do índice de distração proposta pode ser usada com segurança na medição do índice de distração por avaliadores treinados, uma vez que mostra uma adequada repetibilidade e reprodutibilidade das medições oficiais do índice de distração. A simplicidade do processo apresentado torna-o menos demorado e mais econômico.(AU)

The use of semi-automated methodology does not interfere significantly in the activity measurement of the urinary gamma-glutamyltransferase in dogs / A utilização da metodologia semiautomática não interfere significativamente na mensuração da atividade da gama glutamil transferase urinária em cães

The urinary gamma-glutamyltransferase (GGTu) is a precocious indicator of renal lesion and the gold standard for the measurement of its activity is the automated method, although semi-automation is often utilized and studies relating this methodology to the occurrence and intensity of analytical errors are still scarce. Therefore, this work aimed to calculate the systematic and random errors in the determination of the GGTu activity in dogs with the use of the semi-automated method and evaluate if that methodology statistically differs from the automated method. 49 dog urine samples were collected through cystocentesis and centrifuged for separation of the supernatant, which was employed for the measurement of the GGTu activity by automated (reference) and semi-automated methods. Linear regression and Pearson correlation (r) tests were employed for the establishment of the systematic error. The random error was calculated according to Westgard; Hunt (1973). Lin’s concordance correlation coefficient was employed to evaluate the presence of concordance between automated and semi-automated techniques. In the analysis of results, a constant error of + 9.51 UI/L (a=9.5118), a proportional error of –9.37% (b=0.9063) and a random error of 9.91% was observed when the semi-automated methodology was employed. The determination (R2) and Lin coefficients were, respectively, 0.9859 with p<0.0001 and 0.9912, suggesting a great similarity and almost perfect concordance between the two methods. Therefore, the data verified that the semi-automation does not interfere significantly in the measurement of the GGTu activity within the minimum and maximum values observed in the study.

A gama glutamil transferase urinária (GGTu) é um biomarcador precoce de lesão renal e o padrão ouro para mensuração da sua atividade é o método automatizado, apesar disto, a semiautomação é frequentemente utilizada e são escassos os trabalhos que relacionam essa metodologia à ocorrência e intensidade de erros analíticos. Sendo assim, este trabalho teve como objetivo calcular os erros sistemático e randômico na determinação da atividade de GGTu de cães a partir do uso do método semiautomatizado e avaliar se essa metodologia difere estatisticamente do método automático. Coletou-se 49 amostras de urina de cães por cistocentese, as quais foram centrifugadas para separação do sobrenadante, que foi utilizado para a mensuração da atividade da GGTu pelos métodos automático, considerado como referência, e semiautomático. Os testes de regressão linear e correlação de Pearson (r) foram utilizados para o estabelecimento do erro sistemático. O erro randômico foi calculado de acordo com Westgard; Hunt (1973). Para avaliar a presença de concordância entre as técnicas automática e semiautomática foi empregado o coeficiente de concordância de Lin. Na análise dos resultados observou-se a presença de erro constante de + 9,51 UI/L (a= 9,5118), erro proporcional de -9,37% (b=0,9063) e erro randômico de 9,91% quando a metodologia semiautomática foi utilizada. Os coeficientes de determinação (R2) e de Lin calculados foram, respectivamente, 0,9859 com p<0,0001 e 0,9912, indicando alta semelhança e concordância quase perfeita entre os métodos analisados. Dessa maneira, esses dados mostram que a semiautomação não interfere significativamente na mensuração da atividade da GGTu dentro dos valores mínimo e máximo observados no trabalho.

Therefore, the data verified that the semi-automation does not interfere significantly in the measurement of the GGTu activity within the minimum and maximum values observed in the study.(AU)

A gama glutamil transferase urinária (GGTu) é um biomarcador precoce de lesão renal e o padrão ouro para mensuração da sua atividade é o método automatizado, apesar disto, a semiautomação é frequentemente utilizada e são escassos os trabalhos que relacionam essa metodologia à ocorrência e intensidade de erros analíticos. Sendo assim, este trabalho teve como objetivo calcular os erros sistemático e randômico na determinação da atividade de GGTu de cães a partir do uso do método semiautomatizado e avaliar se essa metodologia difere estatisticamente do método automático. Coletou-se 49 amostras de urina de cães por cistocentese, as quais foram centrifugadas para separação do sobrenadante, que foi utilizado para a mensuração da atividade da GGTu pelos métodos automático, considerado como referência, e semiautomático. Os testes de regressão linear e correlação de Pearson (r) foram utilizados para o estabelecimento do erro sistemático. O erro randômico foi calculado de acordo com Westgard; Hunt (1973). Para avaliar a presença de concordância entre as técnicas automática e semiautomática foi empregado o coeficiente de concordância de Lin. Na análise dos resultados observou-se a presença de erro constante de + 9,51 UI/L (a= 9,5118), erro proporcional de -9,37% (b=0,9063) e erro randômico de 9,91% quando a metodologia semiautomática foi utilizada. Os coeficientes de determinação (R2) e de Lin calculados foram, respectivamente, 0,9859 com p<0,0001 e 0,9912, indicando alta semelhança e concordância quase perfeita entre os métodos analisados. Dessa maneira, esses dados mostram que a semiautomação não interfere significativamente na mensuração da atividade da GGTu dentro dos valores mínimo e máximo observados no trabalho.(AU)

Sensitivity to antifungals by Candida spp samples isolated from cases of chronic atrophic candidiasis (CAC)

Abstract The treatment of choice for chronic atrophic candidiasis (CAC), also known as denture stomatitis, is topical antifungal therapy. This study aimed to isolate, identify, and assess the antifungal susceptibility of Candida species from mucosal sites in denture wearers with a diagnosis of CAC and determine the prevalence of associated variables. The sample consisted of 44 patients wearing complete or partial dentures who had a clinical diagnosis of CAC. Using sterile cotton swabs, specimens were collected from the oral mucosa of all patients and grown at 30ºC for 48 h in CHROMagar Candida, as a means of isolating and screening the species. The complementary identification of the species was performed using the VITEK 2 automated system (BioMérieux), as well as the determination of their susceptibility to antifungal agents. Data were analyzed using the chi-square test. STATA 13.1 was used for statistical analysis ( = 5%). Of 44 patients with CAC, 33 (75%) had lesions classified as Newton type II. Yeasts were isolated in 38 cases. The most prevalent species was Candida albicans. None of the isolates were resistant to the antifungals tested. Our findings suggest that current indications for antifungal agents are appropriate. Also, antifungal susceptibility testing and proper fungal identification can help dentists to determine the optimal course of treatment for CAC.

Resumo O tratamento de escolha para candidíase atrófica crônica (CAC), também conhecida como estomatite protética, é a terapia antifúngica tópica. Este estudo teve como objetivo isolar, identificar e avaliar a susceptibilidade antifúngica de espécies de Candida de locais mucosos em portadores de prótese com diagnóstico de CAC e determinar a prevalência de variáveis associadas. A amostra consistiu em 44 pacientes portadores de próteses completas ou parciais que tiveram um diagnóstico clínico de CAC. Usando swab estéril, foram coletados espécimes da mucosa oral de todos os pacientes e cultivados a 30ºC durante 48 h em CHROMagar Candida, como forma de isolamento e triagem das espécies. A identificação complementar das espécies foi realizada no sistema automatizado VITEK 2 (BioMérieux), bem como a determinação da susceptibilidade delas a agentes antifúngicos. Os dados foram analisados usando o teste do qui-quadrado. O STATA 13.1 foi utilizado para análise estatística ( = 5%). Dos 44 pacientes com CAC, 33 (75%) apresentaram lesões classificadas como Newton tipo II. As leveduras foram isoladas em 38 casos. A espécie mais prevalente foi Candida albicans. Nenhum dos isolados foi resistente aos antifúngicos testados. Nossas descobertas sugerem que as indicações atuais para os agentes antifúngicos são apropriadas. Além disso, testes de susceptibilidade antifúngicos e identificação fúngica adequada podem ajudar os dentistas a determinar o curso ótimo de tratamento para CAC.

Methods for glomerular quantification in dogs: a comparative study / Metodologias para quantificação glomerular em cães: um estudo comparativo

It was evaluated the different methodologies for glomerular enumeration described in the literature in a quantitative, double-blind study on the number of glomeruli present in kidney biopsy specimens obtained using a Tru-cut-type biopsy needle. Eighteen samples were taken (n=18) from various regions of canine kidneys harvested immediately after euthanasia. Sample collection was carried out using Tru-cut-type, semi-automated, 16 gauge needles. Reading and evaluation of the specimens were performed independently by four researchers by means of eye loupe inspection, light microscopy, light microscopy with a reduced condenser aperture, and dissection microscopy. Samples were also subjected to histopathological evaluation for comparison purposes. There was no inter-researcher variation for any of the tested methods. The glomerular counts obtained using light microscopy with reduced condenser aperture were similar to those reported in the histopathological evaluation (P=0.44);whereas, the other glomerular enumeration methods yielded significantly lower counts when compared to the histopathological analysis (eye loupe inspection: P<0.01; conventional light microscopy: P=0.02; dissection microscopy: P<0.01).Light microscope with lowering of the condenser lens delivers better results than conventional light microscopy and eye loupe inspection. Results obtained using dissection microscopy and eye loupe inspection did not correlate well with those provided by histopathological evaluation; consequently, these two methods should be avoided.(AU)

Avaliou-se as diferentes metodologias de quantificação glomerular descritas na literatura em um estudo quantitativo, duplo-cego, sobre o número de glomérulos presentes em amostras de biópsias renais obtidas com agulha de biópsia tipo Tru-cut. Dezoito amostras foram coletadas (n=18) de várias regiões de rins caninos colhidos imediatamente após a eutanásia. A coleta das amostras foi realizada com agulhas semi-automáticas de calibre 16, tipo Tru-cut. A leitura e avaliação das amostras foram realizadas de forma independente por quatro pesquisadores por meio de inspeção visual, microscopia de luz, microscopia de luz com redução da lente condensadora e microscopia de dissecção. As amostras também foram submetidas à avaliação histopatológica para fins de comparação e variação do pesquisador para qualquer um dos métodos testados. As contagens glomerulares obtidas por microscopia de luz com redução da lente condensadora foram semelhantes àquelas encontradas na avaliação histopatológica (P=0.44), enquanto que os outros métodos de quantificação glomerular produziram contagens significativamente mais baixas a análise histopatológica (inspeção da lupa dos olhos: P<0.01; microscopia de luz convencional: P=0.02; microscopia dissecação: P<0.01). Microscópio de luz com abaixamento da lente condensadora fornece melhores resultados do que microscopia de luz convencional e inspeção da lupa. As contagens obtidas usando microscopia de dissecção e inspeção de lupa de olho não se correlacionaram bem com aqueles fornecidos pela avaliação histopatológica; consequentemente, estes dois métodos devem ser evitados.(AU)

Indicadores biológicos séricos em veado-campeiro ( Ozotoceros bezoarticus bezoarticus, Linnaeus 1758) de vida livre do Pantanal Sul-Mato-Grossense / Serum biological indicators in free-living pampas deer (Ozotoceros bezoarticus bezoarticus, Linnaeus 1758) of the Pantanal Sul-Mato-Grossense

O objetivo com este estudo foi estabelecer os intervalos de referência de diferentes analitos séricos em Ozotoceros bezoarticus bezoarticus de vida livre. Foram coletadas amostras de sangue de 54 fêmeas e 14 machos adultos, capturados no Pantanal de Mato Grosso do Sul. A determinação das concentrações de cálcio total, albumina, colesterol total, creatinina, glicose, fósforo, proteína total, triglicerídeos e ureia séricas e a atividade das enzimas alanina aminotransferase, aspartato aminotransferase, creatina quinase fração MB e fosfatase alcalina foi realizada em equipamento automático. Valores de globulinas, cálcio total e proporções (razões) entre analitos foram realizados por meio de cálculo matemático. Esta é a primeira descrição do intervalo de referência de parâmetros bioquímicos séricos em veado-campeiro de vida livre do Pantanal de Mato Grosso do Sul. O tamanho da amostra e a distribuição dos dados indicam que os valores médios obtidos são representativos e podem ser usados para a monitorização da saúde, do estado nutricional e do diagnóstico de enfermidades nesse estrato populacional.(AU)

The objective of the present study is to establish the reference intervals of different serum analytes in free - living Ozotoceros bezoarticus bezoarticus.

Determination of the reference interval for the activity of NAcetyl-ß-D-glucosaminidase (NAG) in urine of healthy dogs / Determinação de intervalo de referência para a atividade da NAcetyl-ß-D-glucosaminidase (NAG) na urina de cães sadios

The diagnosis of acute kidney injury by evaluating the activity of urinary enzymes is an important tool especially for its precocity in relation to methods of assessment of renal function considered late as the installation of injury precedes the function change. This study was performed to determine the reference interval for urinary NAG activity (N-Acetyl-β-D-glucosaminidase) in urine of healthy dogs of different breeds, ages and sexes. It was utilized an automated method for the determination of NAG activity standardized for dog urine samples. Through statistical analysis it was observed that NAG is positively correlated with the age of the animal and urine specific gravity but is not interfered by sex or weight. Based on the determination of urinary activity and after correcting the values for a 1,025 urine specific gravity was obtained an reference interval of X '= 3.62U/L±0.66U/L.(AU)

O diagnóstico da injúria renal aguda pela avaliação da atividade de enzimas urinárias é uma importante ferramenta para o médico veterinário, especialmente por sua precocidade em relação aos métodos de avaliação da função renal, considerados tardios, visto que a instalação da injúria precede a alteração da função. Neste estudo foi realizada a determinação do intervalo de referência médio para a atividade urinária de NAG (N-Acetyl- β-D-Glucosaminidase), em urinas de cães hígidos, de diferentes raças, sexos e faixas etárias. Para isso, trabalhou-se com um método automatizado para determinação da atividade de NAG, padronizado para amostras de urina de cães. Por meio de análise estatística, observou-se que a NAG apresenta correlação positiva com a idade do animal e com a densidade urinária, mas não sofre interferência quanto ao sexo ou peso. Com base na determinação da atividade urinária e após corrigir os valores para uma densidade de 1,025, obteve-se um intervalo de referência médio de X´ = 3,62U/L±0,66U/L.(AU)

Interpretation of Coagulation Tendency Contributing to Thrombosis in Vector-Borne Diseases (Ehrlichiosis, Anaplasmosis, Leishmaniosis, and Dirofilariasis) among Dogs

Background: Vector-borne infectious and zoonotic diseases are an important health problem that directly affects human and animal health negatively. Results through evaluation of coagulation disorders among vector-borne diseases should be of beneficial for both human and dogs studies. According to the present authors knowledge reports regarding changes in platelet (PLT) count, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and D-dimer levels in dogs naturally infected with one or more vector-borne pathogens are lacking. Therefore, the present study was aimed to detecting those parameters for relation between diagnosis and prognosis of vector-borne diseases among dogs.Materials, Methods & Results: The material of this study was 46 dogs (36 were naturally infected with vector-borne diseases and 10 were healthy) from different breed, age and of both sexes. Venous blood samples were obtained to detect PLT counts, antibodies of ehrlichiosis, anaplasmosis, borreliosis, leishmaniosis and antigens of Dirofilaria immitis. The diagnosis of vector-borne diseases was performed by using a commercial ELISA assay kits. PLT count was performed with an automated blood cell counter analyser. In addition, PT, APTT and FIB concentrations were measured using a microcoagulometer. D-dimer concentrations were determined using fluorescence immunoassay rapid qu
