Prevalência da co-infecção Leishmania/HIV em pacientes atendidos em unidades de referência do município de Belém

Com o objetivo de investigar a prevalência da co-infecção Leishmania/HIV em pacientes sorologicamente positivos para o HIV, sem histórico da co-infecção, foi realizado um estudo transversal através de análise de ficha clínico-epidemiológica aplicada aos pacientes registrados nas unidades de referência para aids em belém: CASA DIA e URE - DIPE, no período de julho a outubro de 2008. Foram coletadas amostras de sangue de 377 pacientes que concordaram em participar da pesquisa, por análise de IFI e PCR e em 55 deles foi realizada a IDRM. A média de idade foi de 38,2 anos e 59% dos pacientes era do sexo feminino. A carga viral média entre os 249 pacientes que apresentaram informações completas a respeito desta variável, foi de 30952,2. A IFI foi positiva em 08 pacientes e a PCR foi positiva em 22. Um total de 214 pacientes encontrva-se em tratamento com TARV. Foram registrados 218 pacientes com episódios de doenças associados à condição HIV positivos. Cinco pacientes relataram episódio de co-infecção M. leprae/HIV, e nenhum deles apresentou resultado positivo para Leishmania pela PCR. O uso de drogas intravenosas foi relatado por 27 pacientes, porém apenas um apresentou PCR positivo, indicando que a transmissão não foi do tipo inter-humana. Dentre os pacientes que foram submetidos à IDRM, nenhum apresentou reação positiva. No presente trabalho, a técnica de PCR foi mais sensível que a reação de IFI, 6% e 2%, respectivamente.

Prevalência da Rinotraqueíte Bovina (IBR) em touros bubalinos em propriedades localizadas no Amapá e Ilha de Marajó (PA), Brasil

Amostras sanguineas de 188 touros bubalinos, criados em sistema extensivo em areas de varzea, sem controle sanitario e reprodutivo eficiente, com idade de dois a 15 anos, das racas Murrah, Mediterraneo e seus mesticos, foram coletadas em tubos vacutainer esterilizados de 5 mL e avaliadas quanto a presenca de anticorpos para HBV-1, atraves do teste de soroneutrlizacao. Dos 188 touros examinados, somente de 51 foi possivel obter amostras de semen, as quais foram submetidas a analise de RT-PCR. Informacoes acerca da idade, raca e escore de condicao corporal (ECC) dos animais foram observadas. A estatistica descritiva foi aplicada atraves da distribuicao proporcional e determinacao dos quadris e medianas de variaveis categoricas. O estudo foi realizado em animais de oito propriedades, localizadas nos estados do Para e Amapa, regiao Norte do Brasil, encontrando-se distribuidos da seguinte forma: nos municipios de Itaubal do Piriri (N=59), Cutias do Araguari (N=33), Tartarugalzinho (N=14) e Bailique, distrito de Macapa (N=21), totalizando 127 animais no Amapa. Os 73 restantes localizavam-se no estado do Para nos municipios de Soure (N=38) e Muana (N=23), Ilha do Marajo. A analise estatistica constou da aplicacao do teste Binomial para comparar a prevalencia do HBV-1 nas propriedades examinadas nos municipios, e comparar a prevalencia entre as classes de raca, escore corporal e idade. Para avaliar a distribuicao da titulacao de anticorpos para HBV-1, entre Amapa e Marajo, foi utilizado o teste estatistico de Mann- Whitney. Todos os procedimentos foram executados pelo programa BioEstat 5, com nivel de significancia α=0.05. Em todas as propriedades estudadas havia animais positivos, e 82,4% das 188 amostras foram sorologicamente positivas. Entre as racas mediterraneo e Murrah e seus mesticos, houve diferenca real de prevalencia somente entre as racas Mediterraneo e Murrah (p=0,0004). Houve influencia do ECC na prevalencia de touros sorologicamente positivos, sendo que os de ECC=3 apresentaram maior prevalencia que os de ECC < 3 (p=0.009). A prevalencia conforme a idade mostrou que existe uma diferenca significativa (p<0.0001) entre os animais com dois anos e os touros com mais de dois anos de idade, havendo um incremento gradativo das taxas de infeccao com o avancar da idade. A prevalencia no estado do Amapa foi significativamente maior que no Para. As propriedades localizadas nos municipios de Cutias do Araguari, Tartarugalzinho e Bailique (Macapa), apresentram 100% de prevalencia. Foi observado que a titulacao minima ocorreu na maioria dos animais no Marajo, entretanto em somente em 4.8% do rebanho procedente do Amapa teve baixas titulacoes. Todas as 51 amostras de semen apresentaram-se negativas no teste da RTPCR. Concluimos assim que a prevalencia da IBR e altissima em touros bubalinos criados extensivamente no estado do Amapa e Para, Brasil.

Periostin as a modulator of chronic cardiac remodeling after myocardial infarction

OBJECTIVE: After acute myocardial infarction, during the cardiac repair phase, periostin is released into the infarct and activates signaling pathways that are essential for the reparative process. However, the role of periostin in chronic cardiac remodeling after myocardial infarction remains to be elucidated. Therefore, the objective of this study was to investigate the relationship between tissue periostin and cardiac variables in the chronic cardiac remodeling induced by myocardial infarction. METHODS: Male Wistar rats were assigned to 2 groups: a simulated surgery group (SHAM; n = 8) and a myocardial infarction group (myocardial infarction; n = 13). After 3 months, morphological, functional and biochemical analyses were performed. The data are expressed as means±SD or medians (including the lower and upper quartiles). RESULTS: Myocardial infarctions induced increased left ventricular diastolic and systolic areas associated with a decreased fractional area change and a posterior wall shortening velocity. With regard to the extracellular matrix variables, the myocardial infarction group presented with higher values of periostin and types I and III collagen and higher interstitial collagen volume fractions and myocardial hydroxyproline concentrations. In addition, periostin was positively correlated with type III collagen levels (r = 0.673, p = 0.029) and diastolic (r = 0.678, p = 0.036) and systolic (r = 0.795, p = 0.006) left ventricular areas. Considering the relationship between periostin and the cardiac function variables, periostin was inversely correlated with both the fractional area change (r = -0.783, p = 0.008) and the posterior wall shortening velocity (r = -0.767, p = 0.012). CONCLUSIONS: Periostin might be a modulator of deleterious cardiac remodeling in the chronic phase after myocardial infarction in rats.

Efeitos hemodinâmicos da anestesia em plano profundo com infusão intravenosa contínua de propofol ou propofol associado à lidocaína em cães

The hemodynamic effects of total intravenous anesthesia with propofol or propofol in combination with lidocaine were investigated in 12 dogs. In the P group (n=6), the dogs received a loading dose (LD) of 6mg kg-1 of propofol followed by a constant rate infusion (CRI) of 1.25mg kg-1 min-1. In the PL group (n=6), dogs received a LD of 6mg kg-1 of propofol and 1.5mg kg-1 of lidocaine followed by CRIs of 1.0mg kg-1 min-1 and 0.25mg kg-1 min-1 of propofol and lidocaine, respectively. The animals were instrumented for measurement of hemodynamic variables and bispectral index (BIS), recorded at 75, 90, 105 and 120 minutes during anesthesia. Cardiac index, stroke index, systolic, diastolic and mean arterial blood pressures were lower in the P group compared to the PL group (P<0.05). There were no significant differences between groups in heart rate, systemic vascular resistance index and BIS. Plasma concentrations of propofol were lower in group PL than in group P (medians of 5.7 to 6.1mg mL-1 in the P group versus 3.1 to 3.7mg mL-1 in the PL group). Measured lidocaine plasma concentrations (medians of 2.27 to 2.51mg mL-1) were in the range that result in analgesia and were below values that result in toxicity in dogs. The BIS values observed in the two groups of dogs were compatible with deep anesthesia (mean values of 43-46 and 45-49 in groups P and PL, respectively). Maintenance of deep anesthesia with lidocaine-propofol causes less cardiovascular depression than equipotent doses of propofol alone.

Genetic Parameters for Reproductive Traits of Crossbred Buffaloes from Brazil, Estimated by Bayesian Inference

The objective of the study was to estimate heritability for calving interval (CI) and age at first calving (AFC) and also calculate repeatability for CI in buffaloes using Bayesian inference. The Brazilian Buffaloes Genetic Improvement Program provided the database. Data consists on information from 628 females and four different herds, born between 1980 and 2003. In order to estimate the variance, univariate analyses were performed employing Gibbs sampler procedure included in the MTGSAM software. The model for CI included the random effects direct additive and permanent environment factors, and the fixed effects of contemporary groups and calving orders. The model for AFC included the direct additive random effect and contemporary groups as a fixed effect. The convergence diagnosis was obtained using Geweke that was implemented through the Bayesian Output Analysis package in R software. The estimated averages were 433.2 days and 36.7months for CI and AFC, respectively. The means, medians and modes for the calculated heritability coefficients were similar. The heritability coefficients were 0.10 and 0.42 for CI and AFC respectively, with a posteriori marginal density that follows a normal distribution for both traits. The repeatability for CI was 0.13. The low heritability estimated for CI indicates that the variation in this trait is, to a large extent, influenced by environmental factors such as herd management policies. The age at first calving has clear potential for yield improvement through direct selection in these animals.

Comparison between Itraconazole and Cotrimoxazole in the Treatment of Paracoccidiodomycosis

BackgroundThere are no published reports on studies comparing itraconazole (ITC), sulfamethoxazole-trimethoprim (cotrimoxazole, CMX), and ITC followed by CMX (ITC/CMX) in the treatment of paracoccidiodomycosis. This study aimed to compare the efficacy, effectiveness, safety and time to clinical and serologic cure in paracoccidioidomycosis patients treated with ITC or CMX, the antifungal agents most widely used.MethodologyA quasi-experimental study was performed in 177 patients with a confirmed or probable diagnosis of paracoccidioidomycosis. Treatment was divided into two stages: 1) initial, which was continued until clinical cure was achieved and the erythrocyte sedimentation rate decreased to normal values; 2) complementary, which was continued until serologic cure was achieved. Medians were compared via the Mann-Whitney test, and frequencies were compared via the chi-squared test. The assessment of variables as a function of time was performed using Kaplan-Meier curves and Cox regression. The significance level was established as p <= 0.05.Principal FindingsNo difference was found in the efficacy and effectiveness of the initial treatment of 47 individuals given ITC and 130 individuals given CMX; however, the time to clinical cure was shorter in the former compared with the latter group (105 vs. 159 days; p = 0.001), specifically in patients with the chronic form. Efficacy and effectiveness of the three regimens were similar in the complementary treatment; however, the time to serologic cure was shorter when ITC (161 days) or CMX (495 days) was used compared with ITC/CMX (881 days) [p = 0.02]. The independent predictors of a shorter time to serologic cure were treatment with ITC [risk ratio = 6.61 (2.01-21.75)] or with CMX [risk ratio = 5.11 (1.91-13.67)]). The prevalence of side effects was lower with ITC (6.4%) than with CMX (20.0%; p = 0.03).ConclusionsSince ITC induced earlier clinical cure and was better tolerated than CMX, such triazole should be considered the first-choice for PCM treatment.

Whole grain diet for Feedlot Lambs

For a lamb feedlot system became competitive it is essential that an equilibrate nutrition and functional feeding management happens naturally. Therefore, this experiment has the objective to evaluate the efficiency of whole corn grain diet on lambs performance and carcass quality parameters and ruminal papillae development. During the experiment twenty Dorper/Santa Inescrossbred lambs were used, divided randomly in two treatments: control diet and whole grain diet. The experimental design was completely randomized design and data analysis done by SISVAR using the Tukey test at 5% of probability. No statistical differences were observed on the characteristics evaluated for performance and carcass as well as the length and width of ruminal papillae. The composition of the diet together with the weight gain potential of the lambs can explain the good average daily weight gain of 0.284 kg. The initial body condition average was 2.1 (thin) and improved at the end of the trial period achieving3.15 (normal). Carcass yield reached 46.24%, the results is between the range ideal for specialty meat breeds ranging from 40 to 50%. The carcass conformation, fat cover conformation and the thickness of subcutaneous fat found can be classified as medians. Also there was no difference in the characteristics of ruminal papillae. Thus, it is concluded that the use of whole grain diet did not influence the characteristics evaluated; and the choice of diet should be made with regard to profitability, simplicity of use and availability of forage in feedlot.

Análise da flexibilidade e da postura em jovens atletas praticantes de futebol

there is evidence that sport can trigger the onset of postural patterns specific to each modality, regardless of the geopolitical aspects, social, cultural habits of everyday life and ethnicity. Since changes in flexibility are cited as possible precursors of decreased range of motion, thereby harming the mechanics of the lower limbs and gait. Objetcive: The objective of this study was to analyze changes in posture and flexibility in young soccer players. Methods: were assessed 51 youngsters, aged between 14 and 18 years, soccer players registered in the Municipal Presidente Prudente SP and categories of the base of Gremio of Presidente Prudente. Data were collected from the assessment by the postural software assessment, and flexibility tests the Bench, to jail and later by tests of muscle length to jail earlier proposed by Kendall et al , was also collected anthropometric data were later confronted with the results statistically. The results were organized into spreadsheets for computing, which later could be performed the statistical analysis. Values are expressed by means of central tendency and variability as well as medians and 95% confidence intervals. The comparison for each profile height and BMI was made by means of analysis of variance complemented by Tukey test. Were considered the statistical differences when P <0.05. Results: In the sample studied 64% of the subjects classified as normal posture, the same happened with 70.59% of the athletes for flexibility in relation to the center of gravity of the sample had 100% anterior displacement of the trunk and 86.28% with a deviation of center of gravity to the left, showing a tendency to some postural deviations for the group assessed. Conclusion: from the results we can conclude that there was significant relationship between the postural angle of the right leg and left angle of the pelvis with BMI and also ankle angle...

This paper is aimed to analyze the distribution of green areas in public spaces of the Limeira city. This study seeks to diagnose the current situation of the distribution of green areas in the city of Limeira and how these areas contribute to the quality of life of city residents. The concept of public green areas can be defined in different ways , and for this study were considered spaces where there is a prevalence of vegetation, parks , public gardens , squares and medians of avenues performing aesthetic and ecological , whose soil is not completely covered . The presence of urban green areas has several functions, such as a space for recreation , environmental education and interpretation , and thus contribute to a greater closeness between man and nature . The aim of this study is to discuss what benefits, incentives and difficulties exist for the maintenance and expansion of green areas in the city and investigate the population's perception of, and their relationship with, these spaces

CLSM assessment of tubule penetration and bacterial leakage evaluation of two resin-based sealer

Aim: The aims of this study were to assess the penetration of two endodontic sealers (salicylate and epoxy resin-based sealers) into dentinal tubules using CLSM; and to evaluate the bacterial leakage of roots filled with the same sealers associated with gutta-percha. Material and Methods: For sealer penetrability assessment, thirty bovine roots were instrumented and divided into three groups: AHP: EDTA + filling with AH Plus and gutta-percha (n=10), MTAF: EDTA + filling with MTA Fillapex and gutta-percha (n=10), control group: canals were not irrigated with EDTA and were filled with gutta-percha and AH Plus (n=5) or MTA Fillapex (n=5). Rhodamine B was added to the sealers in order to provide adequate fluorescence. The roots were transversely sectioned 3mm from the apex to enable CLSM analysis. Leakage was evaluated for turbidity of the broth in a split chamber model system for 30 days, using Enterococcus faecalis as a microbial marker. Thirty roots were instrumented and divided in four grupos: AHP: filling with AH Plus and gutta-percha (n=10); MTAF: filling with MTA Fillapex and gutta-percha (n=10); positive control: filling with gutta-percha without sealer (n = 5); negative control: sealing with cyanoacrylate to test the seal of the system (n = 5). Results: The medians for dentinal tubule penetration were 6.8% (AHP) and 6.6% (MTAF) (P = 0.82). The average time for bacterial leakage was 8 days in both experimental groups (P = 0.79). Conclusion: MTA Fillapex and AH Plus presented similar behavior regarding dentinal tubule penetration and bacterial leakage.
