Anticoagulação oral em portadores de próteses valvares cardíacas mecânicas: experiência de dez anos

INTRODUÇÃO: Dados da literatura sugerem que as taxas de tromboembolismo e sangramento em pacientes com próteses valvares cardíacas mecânicas podem ser muito reduzidas se a terapia anticoagulante for otimizada. OBJETIVOS: Avaliar a ocorrência de complicações em portadores de próteses valvares cardíacas mecânicas submetidos à terapêutica anticoagulante, otimizada por meio de ambulatório especializado. MÉTODOS: Estudou-se a ocorrência de complicações ao longo de 10 anos em 261 pacientes com próteses valvares cardíacas mecânicas, anticoagulados e acompanhados em ambulatório especializado. Esses pacientes foram divididos em dois grupos conforme porcentual de consultas com tempo de protrombina (RNI) dentro do intervalo desejado: G1-0% a 50,00% e G2-50,01% a 100% das consultas. Foram avaliadas as ocorrências de complicações tromboembólicas e hemorrágicas na sua totalidade, ou subdivididas em maiores e menores, de acordo com a gravidade. Os resultados estão apresentados sob forma de estudo atuarial e de frequência linearizada de ocorrência de eventos. RESULTADOS: O estudo atuarial mostrou que, ao longo do tempo, no grupo G2 (com 50,01% a 100% das consultas com a RNI no intervalo desejado) maior número de pacientes esteve livre da ocorrência de qualquer tipo de evento, de eventos hemorrágicos menores ou da elevação exacerbada da RNI. As frequências linearizadas de ocorrência, em todos os tipos eventos, também foram menores nos pacientes do grupo G2. CONCLUSÕES: O tempo de permanência dentro do intervalo de anticoagulação desejado está diretamente relacionado com a ocorrência de complicações. Entretanto, mesmo com acompanhamento otimizado por meio de ambulatório especializado, apenas cerca de um terço dos pacientes apresentaram nível de anticoagulação adequado em mais da metade das consultas.

Environmental risk factors for canine toxoplasmosis in a deprived district of Botucatu, SP, Brazil

Toxoplasmosis is a worldwide zoonosis caused by Toxoplasma gondii that can infect a large variety of animals, including humans. The present study aimed to evaluate the frequency of anti-T. gondii antibodies in dogs from a peripheral district of Botucatu and to establish the association among some epidemiological variables in order to evaluate risk factors for toxoplasmosis infection. Serum samples from dogs were screened using an indirect fluorescent antibody (IFA) test. Anti-T. gondii antibody prevalence was 56%. The highest titer was 1024 (1.79%) and the most frequent titers were 16 (57.14%) and 64 (33.93%). The chi-square (X-2) test revealed significant association among variables such as dog access to street, ingestion of raw meat and presence of synantropic animals in the domestic environment. These results demonstrate that toxoplasmosis is present in dogs from Jardim Santa Elisa district.

Programa de Pos-Graduacao em Ciencia, Tecnologia e Inovacao em Agropecuaria, Universidade Federal Rural do Rio de Janeiro, BR 465, Km 7, Seropedica, RJ 23890-000, Brasil. E-mail: stelmann.ppgctia@gmail.comA dermoid cyst is a non-neoplasic, benign dermatologic injury. This article describes the finding of a dermoid cyst that was surgically extracted in a nine months aged ewe. The patient was admitted to the Large Animal Veterinary Hospital Department at the Federal Rural of Rio de Janeiro University, with a history of a non-healing wound that also contained fur. The ewe was referred to the surgical service and the histopathologic analysis of the lesion revealed a structure lined by stratified epithelium containing hair follicles, sudoriparous and sebaceous glands, which are conclusive for a dermoid cyst diagnosis.

Efeito do grupo genético sobre as características de carcaça e maciez da carne fresca e maturada de bovinos superprecoces

Objetivou-se estudar o efeito das diferentes proporções de sangue Simental e Nelore sobre as características da carcaça e da carne de bovinos superprecoces. Foram utilizados 72 bovinos jovens inteiros (18 Nelore; 18 ½ Simental × Nelore; 18 Simbrasil e 18 Simental), com 8 meses de idade e 250 kg PV médio inicial. Os animais foram desmamados aos 8 meses de idade em sistema creep-feeding e posteriormente confinados durante 150 dias até atingirem o peso de abate, acima de 465 kg, e abatidos em frigorífico comercial. Os valores de pH e temperatura durante o resfriamento das carcaças foi semelhante para todos os grupos genéticos. da mesma forma, as variáveis carcaça fria, dianteiro e traseiro, não apresentaram diferenças entre os grupos genéticos. Os cortes foram bastante homogêneos, com excessão do contrafilé e do filé-mignon, que foram maiores nos animais Simental. Os animais da raça Nelore e ½ Simental apresentaram maior força de cisalhamento (4,98 e 4,45 kgf) em relação aos Simental e Simbrasil (3,13 e 3,33 kgf). No entanto, após a maturação da carne durante sete dias, não se constataram diferenças entre os valores de maciez entre os grupos. As perdas por evaporação e gotejamento foram maiores na carne in natura para os animais Simental e Simbrasil, no entanto, aos sete dias de maturação se tornaram semelhantes. O sistema de produção de bovinos superprecoces produz carcaças e cortes semelhantes entre as diferentes raças estudadas. Aos sete dias de maturação, a maciez da carne de animais Nelore foi semelhante à dos demais grupos genéticos utilizados neste estudo.

Episodes of water deprivation enhance daily hypertonic NaCl intake in rats

Water and 1.8% NaCl intake was recorded daily in adult male rats (N = 6) submitted to four water deprivations plus four sodium appetite tests, each at the end of each 7-day interval, or in controls (non-deprived, N = 6). Water deprivation was achieved by removing water and 1.8% NaCl for 24 h. Water was then offered for 2 h. At the end of this period, 1.8% NaCl was also offered in addition to water (sodium appetite test). Average daily 1.8% NaCl intake was enhanced from 5.2 ± 1.0 to 15.7 ± 2.5 ml from the first to the fifth week in the experimental group and was unchanged in the control group. Daily water intake was not altered in either group. Thus, repeated episodes of water deprivation enhance daily NaCl intake.

Effect of temporary cements on the shear bond strength of luting cements

Objective: The purpose of this study was to evaluate, by shear bond strength (SBS) testing, the influence of different types of temporary cements on the final cementation using conventional and self-etching resin-based luting cements. Material and Methods: Forty human teeth divided in two halves were assigned to 8 groups (n=10): I and V (no temporary cementation); II and VI: Ca(OH)(2)-based cement; III and VII: zinc oxide (ZO)based cement; IV and VIII: ZO-eugenol (ZOE)-based cement. Final cementation was done with RelyX ARC cement (groups I to IV) and RelyX Unicem cement (groups V to VIII). Data were analyzed statistically by ANOVA and Tukey's test at 5% significance level. Results: Means were (MPa): I - 3.80 (+/- 1.481); II - 5.24 (+/- 2.297); III - 6.98 (+/- 1.885); IV - 6.54 (+/- 1.459); V - 5.22 (+/- 2.465); VI - 4.48 (+/- 1.705); VII - 6.29 (+/- 2.280); VIII - 2.47 (+/- 2.076). Comparison of the groups that had the same temporary cementation (Groups II and VI; III and VII; IV and VIII) showed statistically significant difference (p<0.001) only between Groups IV and VIII, in which ZOE-based cements were used. The use of either Ca(OH) 2 based (Groups II and VI) or ZO-based (Groups III and VII) cements showed no statistically significant difference (p>0.05) for the different luting cements (RelyX (TM) ARC and RelyX (TM) Unicem). The groups that had no temporary cementation (Groups I and V) did not differ significantly from each other either (p>0.05). Conclusion: When temporary cementation was done with ZO- or ZOE-based cements and final cementation was done with RelyX ARC, there was an increase in the SBS compared to the control. In the groups cemented with RelyX Unicem, however, the use of a ZOE-based temporary cement affected negatively the SBS of the luting agent used for final cementation.

LaTBP1: A Leishmania amazonensis DNA-binding protein that associates in vivo with telomeres and GT-rich DNA using a Myb-like domain

Different species of Leishmania can cause a variety of medically important diseases, whose control and treatment are still health problems. Telomere binding proteins (TBPs) have potential as targets for anti-parasitic chemotherapy because of their importance for genome stability and cell viability. Here, we describe LaTBP1 a protein that has a Myb-like DNA-binding domain, a feature shared by most double-stranded telomeric proteins. Binding assays using full-length and truncated LaTBP1 combined with spectroscopy analysis were used to map the boundaries of the Myb-like domain near to the protein only tryptophan residue. The Myb-like domain of LaTBP1 contains a conserved hydrophobic cavity implicated in DNA-binding activity. A hypothetical model helped to visualize that it shares structural homology with domains of other Myb-containing proteins. Competition assays and chromatin immunoprecipitation confirmed the specificity of LaTBP1 for telomeric and GT-rich DNAs, suggesting that LaTBP1 is a new TBP. (C) 2007 Elsevier B.V.
