Resumo Objetivo Avaliar a frequência de anomalias congênitas (ACs) estruturais no centro-oeste brasileiro e a associação com fatores de risco maternos. Métodos Estudo prospectivo, observacional, caso-controle, baseado em uma população hospitalar. Foram analisadas gestantes atendidas em um serviço de medicina fetal no Brasil, no período de outubro de 2014 a fevereiro de 2016. Foram analisadas 357 gestantes, dentre as quais 223 tiveram fetos com ACs estruturais (grupo controle) e 134 tiveram fetos estruturalmente normais (grupo controle). A história clínica foi feita antes da consulta de pré-natal, e o diagnóstico da AC estrutural foi realizado por ultrassonografia. Resultados Observou-se uma frequência de 64,27% (n = 223) de gestantes com fetos com ACs estruturais. As ACs estruturais mais frequentes foram as do sistema nervoso central (30,94%), seguidas das anomalias do sistema gênito-urinário (23,80%), e, por fim, das ACs múltiplas (16,60%). Antecedentes de crianças com AC (razão de probabiliade [RP]: 3,85; p = 0,022), antecedentes familiares (RP: 6,03; p = < 0,001), e consanguinidade entre os grupos progenitores (RP: 4,43; p = 0,034) influenciaram a ocorrência de AC estrutural. Conclusão As ACs mais frequentes foram as do sistema nervoso central, as do sistema gênito-urinário, e as ACs múltiplas. Os fatores de risco maternos que podem ter influenciado a ocorrência de AC estrutural foram antecedentes de crianças com AC, história familiar, e a consanguinidade entre os pais.

Abstract Objective To evaluate the frequency of structural congenital anomalies (CAs) in the midwest of Brazil and its association with maternal risk factors. Methods This was a prospective, observational, case-control study based on a hospital population. Pregnant women attended at a fetal medicine service in Brazil were analyzed in the period from October 2014 to February 2016.A total of 357 pregnant women were included, 223 of whom had fetuses with structural anomalies (group case), and 134 of whom had structurally normal fetuses (control group). The clinical history was made previous to prenatal consultation, and the diagnosis of the structural CA was performed through ultrasound. Results A frequency of 64.27% (n = 223) of pregnant women with fetuses with structural anomalies was observed. The most frequent structural CAs were those of the central nervous system (30.94%), followed by anomalies of the genitourinary system (23.80%), and, finally, by multiple CAs (16.60%). The background of previous children with CAs (odds ratio [OR]: 3.85; p = 0.022), family history (OR: 6.03; p = < 0.001), and consanguinity between the progenitors (OR: 4.43; p = 0.034) influenced the occurrence of structural CA. Conclusion The most frequent CAs are those of the central nervous system, followed by those of the genitourinary system, and then multiple anomalies. The maternal risk factors that may have influenced the occurrence of structural CA were previous children with CA, family history, and consanguinity among the parents.

Resumo Objetivo Avaliar e comparar a prevalência de anomalias congênitas (ACs) estruturais de acordo com o índice de massa corporal (IMC) materno. Métodos Estudo transversal envolvendo gestantes com fetos diagnosticados com ACs estruturais por ultrassonografia morfológica entre novembro de 2014 e janeiro de 2016. O estado nutricional das gestantes foi classificado de acordo como valor bruto do índice de massa corporal. As gestantes foram categorizadas em quatro grupos: baixo peso, peso adequado, sobrepeso e obesidade. A análise estatística foi realizada no programa Stata/SE versão 12.0 (Stata Corporation, College Station, TX), comvalores de p ≤ 0,05 considerados estatisticamente significantes. Resultados Um total de 223 gestantes tiveram fetos diagnosticados com ACs. A prevalência de AC estrutural emgestantes combaixo peso foi de 20,18%, emgestantes com peso adequado foi de 43,50%, em gestantes com sobrepeso foi de 22,87%, e em gestantes com obesidade foi de 13,45%. A prevalência de anomalias do sistema nervoso central (SNC) e do sistema geniturinário foi alta para os quatro grupos. Observou-se associação positiva entre múltiplas anomalias em gestantes com peso adequado (razão de prevalência [RP] = 1,65; p ≤ 0,004) e entre anomalias do sistema linfático em gestantes obesas (RP = 4,04, p ≤ 0,000). Conclusão A prevalência das anomalias do SNC e do sistema geniturinário foi alta em todas as categorias de IMC. Gestantes obesas foram associadas a anomalias do sistema linfático. Portanto, o rastreamento e a identificação dos fatores de risco para as AC são importantes, independentemente do IMC materno. Nossos achados reforçam a importância de discutir com gestantes sobre a nutrição materna e seu efeito no desenvolvimento fetal e no desfecho neonatal.

Abstract Objective To evaluate and compare the prevalence of structural congenital anomalies (CAs) according to maternal body mass index (BMI). Methods The present cross-sectional study involved pregnant women with fetuses diagnosed with structural CAs through morphological ultrasonography between November 2014 and January 2016. The nutritional status of the pregnant women was classified according to the gross value of the body mass index. The pregnant women were categorized into four groups: low weight, adequate weight, overweight, and obesity. Statistical analysis was performed using Stata/SE version 12.0 (Stata Corporation, College Station, TX), with values of p ≤ 0.05 considered statistically significant. Results A total of 223 pregnant women had fetuses diagnosed with CAs. The prevalence of structural CAs in pregnant women with lowweight was of 20.18%, of 43.50% in pregnant women with adequate weight, of 22.87% in pregnant women with overweight, and of 13.45% in pregnant women with obesity. The prevalence of central nervous system (CNS) anomalies and of genitourinary systemanomalieswas high for the four groups of pregnant women. A positive association was observed between multiple anomalies in pregnant women with adequate weight (prevalence ratio [PR] = 1.65; p ≤ 0.004) and between anomalies of the lymphatic system in obese pregnant women (PR = 4.04, p ≤ 0.000). Conclusion The prevalence of CNS and genitourinary systemanomalies was high in all of the BMI categories. Obese pregnancies were associated with lymphatic system anomalies. Therefore, screening and identification of the risk factors for CAs are important, regardless of the maternal BMI. Our findings reinforce the importance of discussing with pregnant women maternal nutrition and its effect on fetal development and on neonatal outcome.

Abstract: En | Text: En | PDF: En

The current yellow fever outbreak in Brazil is the most severe one in the country in recent times. It has rapidly spread to areas where YF virus (YFV) activity has not been observed for more than 70 years and vaccine coverage is almost null. Here, we sequenced the whole YFV genome of two naturally infected howler-monkeys (Alouatta clamitans) obtained from the Municipality of Domingos Martins, state of Espírito Santo, Brazil. These two ongoing-outbreak genome sequences are identical. They clustered in the 1E sub-clade (South America genotype I) along with the Brazilian and Venezuelan strains recently characterised from infections in humans and non-human primates that have been described in the last 20 years. However, we detected eight unique amino acid changes in the viral proteins, including the structural capsid protein (one change), and the components of the viral replicase complex, the NS3 (two changes) and NS5 (five changes) proteins, that could impact the capacity of viral infection in vertebrate and/or invertebrate hosts and spreading of the ongoing outbreak.

ABSTRACT The present study evaluated a probiotic and a competitive exclusion product injected in ovo on day 18 of incubation together with Marek's disease vaccine in eggs of 56-week-old broiler breeders. Three experiments were carried out. The first trial evaluated the effect of treatments on hatchability, cecal colonization of Salmonella Heidelberg (SH), and intestinal mucosa immunity (immunoglobulin A levels in the intestinal fluid). The second trial evaluated the viability of the microorganisms in the products inoculated in a solution containing diluent and Marek's disease vaccine. The third trial evaluated the colonization of the cecal microbiota in non-challenged chickens during first four days of life by culturing cecal samples under aerobic and anaerobic conditions. Hatchability was not affected by the treatments. SH cecal counts were reduced in three-day-old broilers inoculated in ovo with the competitive exclusion product. Liver and spleen pool SH counts were not different among treatments. Broilers inoculated in ovo presented higher intestinal IgA titers 24 hours after SH challenge compared with the controls. When birds were not challenged, lower cecal microbial counts in aerobic culture were determined in the control group than in the probiotic group on day 3, and in the competitive exclusion group on day 2 when cultured in anaerobiosis. The products inoculated and diluted in the vaccine solution were viable at all analyzed periods when cultured in anaerobiosis. The results of this study suggest in-ovo inoculation is an effective route for the administration of the evaluated products, which effectively enhanced the broilers' immune response to a SH challenge, as shown by the increase in IgA titers, and the reduction in cecal Salmonella Heidelberg colonization with the in-ovo inoculation with the competitive exclusion product.

Resumo Objetivo Avaliar a eficácia de quatro tipos de substâncias usadas para ajuste do pH da água de coco (AC) sobre a viabilidade de fibroblastos humanos (HFF). Material e método O pH da AC natural e industrializada foi ajustado para pH 7,0 utilizando: (1) Hidróxido de Sódio (NaOH), (2) bicarbonato de sódio (NaHCO3), (3) Trietanolamina (C6H15NO3), (4) 2-Amino-2- Methil-1-propanol (C4H11NO). Células HFF foram plaqueadas em 2×104 células/poço em placas de 96 poços e mantidas nas diferentes soluções de AC acima durante 2 h e 4 h. Controle positivo foi representado por HFF mantidas em DMEM e o controle negativo por água da torneira. A viabilidade celular foi avaliada pelo método de MTT Formazan. Os dados foram analisados por 3-way ANOVA seguido pelo teste de Tukey e Dunnett. Resultado A viabilidade celular não é influenciada pelo período de avaliação, e as interações entre AC e período de avaliação, AC e método de ajuste de pH, método de ajuste de pH e período de avaliação (p>0,05). Conclusão O produto utilizado para ajuste do pH não interfere na viabilidade de FH, embora, haja uma tendência de melhor desempenho em AC natural.

Abstract Objective This study evaluated four types of pH adjustment of the coconut water (CW) on viability of human fibroblasts (HFF). Material and method Natural and industrialized CW were adjusted to pH 7.0 using: (1) Sodium Hidroxide (NaOH), (2) Sodium bicarbonate (NaHCO3), (3) Triethanolamine (C6H15NO3), (4) 2-Amino-2-Methil-1-Propanol (C4H11NO). Fibroblasts were plated at 2×104/ well in 96 well plates and maintained in the CW solutions for 2 h and 4 h. Positive control was represented by HFF maintained in DMEM and the negative control by tap water. Cell viability was analyzed by MTT formazan method. Data were analyzed by 3-way ANOVA followed by Tukey’s and Dunnet’s test. Result There are no significant effect on the cell viability regarding type of CW, period of evaluation, and the interactions between CW and period of evaluation, CW and pH adjustment method, pH adjustment method and period of evaluation (p>0.05). Conclusion The product used for CW pH adjustment did not influenced HFF viability, thought there are a tendency of better performance in natural CW.

RESUMO CONTEXTO E OBJETIVO: As hemoglobinopatias estão entre as alterações genéticas mais comuns e mundialmente difundidas, variando conforme a composição étnica e/ou geográfica. Nosso objetivo foi verificar a incidência de hemoglobinopatias por métodos de triagem laboratorial e sua associação com a etnia em 1.004 recém-nascidos. TIPO DE ESTUDO E LOCAL: Estudo transversal; realizado em um hospital público de referência do Triângulo Mineiro, Minas Gerais, Brasil. MÉTODOS: Avaliação qualitativa das hemoglobinas foi realizada por eletroforese em acetato de celulose: em pH alcalino para identificação do perfil hemoglobínico, em pH ácido para diferenciação das Hb S da Hb D e Hb C da Hb E, e outras que migrem em posições semelhantes em pH alcalino e em pH neutro para detecção de Hb Bart's, identificada na talassemia alfa (α-thal); e avaliação quantitativa das hemoglobinas pelo método de eluição após eletroforese. RESULTADOS: Houve predomínio da α-thal, com 105 (10,46%) casos, seguida da Hb S, com 61 casos (6,08% - 46 Hb AS, 2 Hb SS e 13 Hb S/α-thal), 9 casos (0,9%) de Hb AC e 6 (0,6%) sugestivos de beta-talassemia (β-thal). A incidência de hemoglobinopatias foi significantemente maior em afrodescendentes. CONCLUSÕES: Esses achados reforçam a importância do Programa Nacional de Triagem Neonatal para o diagnóstico das síndromes falciformes e hemoglobinopatias C, D, E e β-thal e robustecem os dados da literatura sobre a necessidade da pesquisa da α-thal em sangue de cordão (não identificada pelo Programa Nacional) e em pacientes com anemia microcítica não responsivos à ferroterapia.

ABSTRACT CONTEXT AND OBJECTIVE: Hemoglobinopathies are among the commonest and most widespread genetic disorders worldwide. Their prevalence varies according to ethnic composition and/or geographical region. The aim of this study was to investigate the presence of hemoglobinopathies and their association with ethnicity among 1,004 newborns, to confirm the guideline of the Brazilian National Neonatal Screening Program. DESIGN AND SETTING: Cross-sectional study conducted in a public referral hospital in the Triângulo Mineiro region, Minas Gerais, Brazil. METHODS: Qualitative assessment of hemoglobin was performed through electrophoresis on cellulose acetate: at alkaline pH to identify the hemoglobin (Hb) profile and at acid pH to differentiate Hb S from Hb D and Hb C from Hb E and others that migrate to similar positions at alkaline pH. Neutral pH was used to detect Hb Bart's identified in alpha thalassemia (α-thal). The elution method after electrophoresis was used to quantitatively assess hemoglobins. RESULTS: There was predominance of α-thal, with 105 cases (10.46%), followed by Hb S with 61 cases (6.08%, comprising 46 Hb AS, 2 Hb SS and 13 Hb S/α-thal), 9 cases (0.9%) of Hb AC and 6 cases (0.6%) suggestive of beta thalassemia (β-thal). The frequency of hemoglobinopathies was significantly higher among Afro-descendants. CONCLUSIONS: These findings corroborated of the National Neonatal Screening Program for diagnosing sickle cell disease and Hb C, Hb D, Hb E and β-thal hemoglobinopathies.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Uma análise geral do comportamento do “Cebus apella” mostra que este primata quando desloca para se alimentar ou realizar outra atividade apresenta diferentes maneiras de locomoção. Estas informações mostram que o músculo bíceps braquial deste animal é usado freqüentemente nas suas atividades de locomoção, mas deve ser lembrado ainda que este músculo é usado também para desenvolvimento de outras atividades como esconder-se, procurar objetos, vasculhar arboredos, além de cavar o chão. Considerando-se o exposto acima decidiu-se pesquisar as características histoenzimológicas do músculo bíceps braquial do macaco-prego com o objetivo de comparar se este músculo esta melhor adaptado para funções posturais ou fásicas. As amostras foram retiradas das regiões superficiais e profundas; inserções proximais (medial e lateral) e distal de seis macacos-prego machos e adultos, os quais foram submetidos às reações de m-ATPase, NADH-Tr. Baseado nos resultados das reações, as fibras foram classificadas em Fast Twitch Glycolitic (FG), Fast Twitch Oxidative Glycolitic (FOG) e Slow Twitch (SO). Quanto à área dos diferentes tipos de fibras, os resultados encontrados foram semelhantes em todas as amostras estudadas, e as fibras de contração rápida foram sempre maiores do que as de contração lenta (FG=FOG>SO). Os dados obtidos sobre a frequência foram: nas três regiões superficiais estudadas FOG=FG>SO; nas regiões profundas das inserções proximais FOG=FG=SO e na inserção distal FOG>FG=SO. Baseado nestes dados pode-se concluir que o músculo bíceps braquial do macaco-prego está bem adaptado tanto para atividades posturais como fásicas.

A general analysis of the behaviour of “Cebus” shows that when this primate moves position to feed or perform another activity, it presents different ways of locomotion. This information shows that the brachial biceps muscle of this animal is frequently used in their locomotion activities, but it should also be remembered that this muscle is also used for other development activities like hiding, searching for objects, searching out in the woods, and digging in the soil. Considering the above, it was decided to research the histoenzimologic characteristics of the brachial biceps muscle to observe whether it is better adpted to postural or phasic function. To that end, samples were taken from the superficial and deep regions, the inserts proximal (medial and lateral) and distal brachial biceps six capuchin monkeys male and adult, which were subjected to the reactions of m-ATPase, NADH-Tr. Based on the results of these reactions fibres were classified as in Fast Twitch Glycolitic (FG), Fast Twitch Oxidative Glycolitic (FOG) and Slow Twitc (SO). In general, the results, considering the muscle as a whole, show a trend of frequency FOG> FG> SO. The data on the frequency were studied on three superficial regions FOG=FG>SO; the deep regions of the inserts proximal FOG=FG=SO and inserting the distal FOG>FG=SO. In conclusion, the biceps brachii of the capuchin monkey is well adapted for both postural and phasic activities.

FUNDAMENTO: Os gastos com cirurgia de revascularização do miocárdio (RVM) e angioplastia coronariana (AC), representaram importante ônus para o SUS. OBJETIVO: Analisar gastos do SUS com RVM e AC e sua performance nos hospitais do Estado do Rio de Janeiro (ERJ), de 1999 a 2008. MÉTODOS: As informações provieram das AIH pagas dos hospitais com mais de 100 revascularizações. As taxas de letalidade foram ajustadas por modelos Poisson (covariáveis idade, dias de permanência no hospital e gasto em UTI). Foram construídos índices de gasto médio relativo, dividindo-se o valor médio da fração de gasto em cada hospital pelo gasto médio no ERJ, em dólares. Para análise estatística empregou-se o Stata. RESULTADOS: Foram pagas 10.983 RVM e 19.661 AC em 20 hospitais nos 10 anos, com valores médios de US$ 3.088,12 e 2.183,93, respectivamente. A taxa de letalidade nas RVM flutuou de 9,2%-1999 para 7,7%-2008, com valores extremos de 5,0%-9,2% e nas AC de 1,6%-1999 para 1,5%-2008, com valores extremos de 0,9%-2,3%. Os hospitais diminuíram a realização de RVM e duplicaram a de AC. Idade, tempo de internação e gastos em UTI correlacionaram-se significativamente com a letalidade nas RVM e AC pagas no ERJ. Em média, os gastos com os serviços hospitalares representaram 41% do total das RVM e 18% das AC, e os com as órteses e próteses, 55% das AC e 28% nas RVM. CONCLUSÃO: Evidencia-se necessidade de melhorar a qualidade do atendimento das instituições que realizam RVM e AC pagas pelo SUS.

BACKGROUND: Expenses with coronary artery bypass grafting (CABG) surgery and coronary angioplasty (CA) represented a significant cost to SUS. OBJECTIVE: To analyze SUS expenses with CABG and CA and their performance in hospitals in the state of Rio de Janeiro (SRJ), from 1999 to 2008. METHODS: The information came from paid HAA in hospitals with more than 100 revascularization procedures. Mortality rates were adjusted by Poisson (with covariates age, length of hospital stay and ICU expenses). Mean relative cost indices were calculated by dividing the mean value of the cost fraction spent in each hospital by the mean expense in the SRJ in U.S. dollars. Stata software was used for statistical analysis. RESULTS: A total of 10,983 CABG and 19,661 CA were paid by SUS in 20 hospitals during the 10 years, with mean values of US$ 3,088.12 and 2,183.93, respectively. The mortality rate in CABG varied from 9.2%-1999 to 7.7%-2008, with ranges of 5.0%-9.2% and in CA, from 1.6%-1999 to 1.5%-2008, with ranges of 0.9%-2.3%. The hospitals decreased the number of CABG procedures and doubled CA procedures. Age, time of hospital stay and ICU costs significantly correlated with lethality in CABG and CA paid by SUS in the SRJ. On average, hospital service costs represented 41% of the total cost of CABG and 18% of CA, and with ortheses and prostheses, 55% in CA and 28% in CABG. CONCLUSION: It is clear the need to improve the quality of healthcare service in institutions that perform CABG and CA paid by SUS.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

OBJETIVO: Estimar a letalidade nos procedimentos de doenças isquêmicas do coração (DIC) aguda e crônica e por revascularização miocárdica (RVM) e angioplastia coronariana (AC) nos hospitais cadastrados no SIH/SUS (Sistema de Informações Hospitalares/Sistema Único de Saúde) no Estado do Rio de Janeiro (ERJ), de 1999 a 2003. MÉTODOS: Os procedimentos considerados de RVM e de AC provieram do Datasus. As taxas foram padronizadas por sexo, idade e gravidade de doença, tendo como padrão todos os procedimentos de alta complexidade cardiovascular, realizados no ERJ em 2000. Os grupos de DIC são: angina, infarto agudo do miocárdio, outras DIC agudas e DIC crônicas. RESULTADOS: As letalidades por angina, IAM, outras DIC agudas e DIC crônicas foram de 2,8%, 16,2%, 2,9% e 3,9%, respectivamente, no ERJ. As taxas de letalidade, ajustadas por idade, sexo e grupo diagnóstico, nas RVM e AC foram elevadas, variando entre 1,9% e 12,8% nas RVM, e atingindo 3,2% nas AC, e de 2,3% e 11,1%, quando o tratamento clínico era realizado. CONCLUSÃO: As RVM e AC no tratamento das DIC no ERJ vêm aumentando progressivamente. A letalidade esteve acima do desejável, principalmente nas internações por DIC crônicas (5,4% e 1,7%, respectivamente). O tratamento clínico otimizado parece boa opção terapêutica, reservando-se as RVM e AC para os casos de pior prognóstico. A letalidade no IAM com tratamento clínico foi semelhante à existente quando não se utilizam trombolíticos (16,7%).

OBJECTIVE: To estimate the lethality rate of acute and chronic ischemic heart disease (IHD) procedures, coronary artery bypass graft (CABG) procedures and percutaneous transluminal coronary angioplasty (PTCA) procedures in the hospitals that are registered as service providers for the Hospital Information System / Single Healthcare System (SIH/SUS) plan in the state of Rio de Janeiro (RJ) between 1999 and 2003. METHODS: The procedures considered as CABGs and PTCAs were provided by Datasus (SUS databank). The rates were standardized in accordance with gender, age, and disease severity. The common factors among these procedures are that they are highly complex cardiovascular procedures performed in RJ in the year 2000. The IHD groups are: angina, acute myocardial infarction, other acute IHDs and chronic IHDs. RESULTS: Lethality rates for angina, acute myocardial infarction (AMI), other acute and chronic IHDs were 2.8%, 16.2%, 2.9% and 3.9%, respectively, in the RJ. The lethality rates for CABG and PTCA, adjusted by age, sex and diagnostic groups, were elevated ranging from 1.9% to 12.8% for CABG procedures and as high as 3.2% for PTCA. When medical therapy was performed the rates were 2.3% for CABG and 11.1% for PTCA. CONCLUSION: There has been a progressive increase in the number of CABG and PTCA procedures to treat IHDs in the RJ. Lethality rates were above the desirable level, mainly for chronic IHD hospital admissions (5.4% and 1.7%, respectively). Optimized medical therapy appears to be a worthwhile therapeutic option, reserving CABG and PTCA procedures for the cases with the worst prognoses. Lethality rates for AMI with medical therapy was comparable to current rates when thrombolytics were not used (16.7%).

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

O presente artigo descreve um novo método para a síntese de filmes finos de óxidos metálicos. Um filamento de metal, que pode ser aquecido por uma fonte de corrente alternada é instalado numa câmara de vácuo. Por meio de um fluxômetro de massa, oxigênio pode ser admitido no interior da câmara. Da reação entre o oxigênio e o metal do filamento aquecido, espécies de óxidos voláteis Me xOy, onde Me é o metal, são formadas, se condensando num substrato colocado próximo ao filamento, formando o filme. Foi observado que os filmes finos de WxOy e Mo xOy podem ser depositados de forma satisfatória por este novo método. Embora várias outras técnicas de análise tenham sido usadas para caracterizar os óxidos, esta nota enfatiza os resultados obtidos por espectroscopia de fotoelétrons de raio-X (XPS).

This short report describes a novel method for the synthesis of metal oxide thin films. The experimental setup consists of a metal filament installed inside a vacuum chamber. The filament can be heated by an ac power supply while oxygen is admitted into the chamber using a mass flowmeter. From reactions between oxygen and the heated metal filament, volatile oxide species, Me xOy, where Me is the metal, can be formed, condensing on a nearby substrate. We have observed that thin films of WxOy and Mo xOy can be satisfactorily deposited by this novel method. Although several techniques were used to characterize the oxides, this note emphasizes the results obtained by X-ray Photoelectron Spectroscopy (XPS).

O objetivo deste trabalho foi avaliar a utilização da polpa de citros peletizada (PCP) como cama de frango, bem como analisar a composição bromatológica desse material. O experimento foi constituído de 1.792 pintos de um dia-machos e dividido em duas fases: 1 a 21 e 35 a 49 dias. Foi utilizado o delineamento em blocos ao acaso, com quatro repetições, em esquema fatorial 2x2x2, sendo os fatores tipo de cama: PCP e maravalha x altura de cama: 7 e 10 cm x densidade: 10 e 14aves/m². Foram avaliados os parâmetros: gsnho de peso(GP), consumo de ração (CR), conversão alimentar (CA),viabilidade (V), incidência de lesões no coxim plantar e de calo de peito, matéria seca (MS) e pH da cama aos 21 e 49 dias. Para verificar as possíveis alterações bromatológicas na cama foram feitas análises de Weende e Van Soest, bem como de energia bruta. Independentemente da altura da cama, as aves criadas em PCP numa densidade de 14 aves/m² apresentaram piores resultados de GP e CR no período de 35 a 49 dias. Em geral, os resultados de GP e CR foram mais influenciados pelas densidades do que pelos materiais utilizados. Não houve diferença significativa entre os tratamentos para ambas as lesões. De uma maneira geral, a MS da cama de PCP foi maior enquanto o pH foi menor quando comparados com a maravalha. Nas análises bromatológicas, observou-se um efeito significativo dos tratamentos para todas as variáveis, com exceção da MM, a qual não apresentou diferença entre as médias (p>0,05). Melhores valores de PB, FDN e FDA foram obtidos com a cama de PCP.

The object of this experiment was to evaluate the citrus pulp-pelleted (CPP) as a broiler litter and their chemical composition. The experiment used 1792 one day-old males, and it was divided into two phases: 1 to 21 and 35 to 49 days of age. The experimental design was a factorial 2x2x2 with four replicates. The factors were: type of broiler litter (CPP and wood shaving), broiler litter depth (7 and 10 cm) and stocking densities (10 and 14 broilers/m²). The parameters analyzed were: weight gain (WG), feed consumption(FC), feed conversion, incidence of breast blister and foot pad lesion, survivability, dry matter and pH of the broiler litter (21 and 49 days old). To evaluate the possible alteration in the litter chemical composition Weende and van Soest analyses was performed and gross energy was also determined. Independently of depth of litter, the broilers reared on CPP and in the density of 14 broiler/m² showed worse results to WG and FC of 35 to 49 days of age. The results of WG and FC were more affected by the density than the types of broiler litter. There was no significant difference among the treatments for footpad lesion and for lesions of breast blister. The dry matter was higher in CPP than wood shaving. The pH of the broiler litter of CPP was smaller than wood shaving. The chemical analysis showed significant differences due to treatment (p<0.05) for all variables except to mineral matter (MM), with no significant differences between the means. Best values of CP, NDF, ADF were obtained with the CPP used as material for broiler litter.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

O estudo objetivou: estudar a prevalência de potencial tardio, em portadores de cardiopatia chagásica crônica, e sua relação com taquicardia ventricular sustentada. Foram estudados pelo eletrocardiograma de alta resolução 192 pacientes com Cardiopatia Chagásica Crônica, sendo 96 (50%) do sexo masculino. A idade variou entre 17 e 75 anos (média de 42,93). De acordo com presença ou ausência de bloqueio de ramo e taquicardia ventricular sustentada foram constituídos 4 grupos. Admitiu-se a presença de potencial tardio, com filtro de 40 Hz, nos grupos sem bloqueio de ramo, quando a duração do QRS filtrado ≥ 110 ms, duração do sinal abaixo de 40 µV ≥ 35ms e voltagem da raiz quadrada dos últimos 40ms (VM 40) ≤ 20 µV. Nos grupos com Bloqueio de ramo considerou-se o VM40 ≤ 14 µV como indicativo de potencial tardio. RESULTADOS: nos grupos sem bloqueio de ramo o potencial tardio esteve presente em 21(78%) dos pacientes com taquicardia ventricular sustentada e em 22(31%) dos sem taquicardia ventricular sustentada (p<0,001), com sensibilidade (S) 78%, especificidade (E) 70% e acurácia (Ac) 77%. O potencial tardio esteve presente em 30 (48%) dos pacientes sem taquicardia ventricular sustentada e em 20 (67%) com taquicardia ventricular sustentada nos grupos com bloqueio de ramo (p=0,066) com S, 66%, E, 52% e Ac, 57%. No seguimento, 12 (21%) pacientes apresentaram recorrência de taquicardia ventricular sustentada: 91,6% destes pacientes tinham potencial tardio. Ocorreram quatro óbitos sem relação com eventos arrítmicos, todos pertencentes ao grupo com bloqueio de ramo e sem taquicardia ventricular sustentada, e com potencial tardio ausente. CONCLUSÕES: Potencial tardio ocorreu em 77,7% dos pacientes com taquicardia ventricular sustentada e sem bloqueio de ramo. Na ausência de bloqueio de ramo o eletrocardiograma de alta resolução diferenciou pacientes com e sem taquicardia ventricular sustentada. Nos grupos sem bloqueio de ramo observou-se S=78% , E=70% e Ac= 72%. Nos grupos com bloqueio de ramo, em 66,6% dos casos, houve associação entre potencial tardio e taquicardia ventricular sustentada. A recorrência de taquicardia ventricular sustentada esteve presente em 21% dos casos e destes 91,6% tinham potencial tardio.

The aim of the study was to register the prevalence of late potentials (LP) in patients with chronic Chagas' heart disease (CCD) and the relationship with sustained ventricular tachycardia (SVT). 192 patients (96 males), mean age 42.9 years, with CCD were studied through a Signal Averaged ECG using time domain analysis. According to presence or absence of bundle branch block (BBB) and SVT, four groups of patients were created: Group I (n = 72): without SVT (VT-) and without BBB (BBB-): Group II (n = 27): with SVT (VT+) and BBB-; Group III (n = 63): VT- and with BBB (BBB+); and Group IV (N = 30): VT+ and BBB+. The LP was admitted, with 40 Hz filter, in the groups without BBB using standard criteria of the method. In the group with BBB, the root-mean-square amplitude of the last 40 ms (RMS) < =14µV was considered as an indicator of LP. RESULTS: In groups I and II, LP was present in 21 (78%) of the patients with SVT and in 22 (31%) of the patients without SVT (p < 0.001), with Sensitivity (S) 78%; Specificity (SP) 70% and Accuracy (Ac) 72%. LP was present in 30 (48%) of the patients without and 20 (67%) of the patients with SVT, in groups III and IV. p = 0.066, with S = 66%; SP = 52%; and Ac = 57%. In the follow-up, there were 4 deaths unrelated to arrhythmic events, all of them did not have LP. Eight (29,6%) of the patients from group II and 4 (13%) from group IV presented recurrence of SVT and 91,6% of these patients had LP. CONCLUSIONS: LP occurred in 77.7% of the patients with SVT and without BBB. In the groups with BBB, there was association of LP with SVT in 66,6% of the cases. The recurrence of SVT was present in 21% of the cases from which 91,6% had LP.
