OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

Abstract The spittlebugs Mahanarva spectabilis economically challenges cattle production of neotropical regions, due to its voracious feeding on tropical grasses. Here, we evaluated biochemical responses of the interaction between M. spectabilis and the widely cultivated tropical grasses Brachiaria spp. (i.e., brizantha and decumbens) and elephant grasses (cvs. Roxo de Botucatu and Pioneiro), regarding lipoxygenases, protease inhibitors, phytohormones, and proteolytic activities in the midgut of M. spectabilis. The M. spectabilis-infested grasses increased lipoxygenases activity, except for cv. Pioneiro. The levels of the phytohormones jasmonic and abscisic acids were similarly low in all genotypes and increased under herbivory. Furthermore, salicylic acid concentration was constitutively higher in Brachiaria sp., increasing only in spittlebug-infested B. decumbens. M. spectabilis infestations did not induce increases of protease inhibitors in any forage grass type. The trypsin activity remained unaltered, and the total proteolytic activity increased only in B. decumbens-fed insects. Our findings revealed that most forage grasses exposed to spittlebugs activate the lipoxygenases pathway, resulting in increased abscisic and jasmonic acids. However, greater amounts of these hormones do not induce protease inhibitory activity in response to spittlebug attack. This knowledge certainly helps to guide future projects aiming at reducing the impact of spittlebugs on forage production.

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

This work describes the synthesis and characterization of two new compounds with ligand opy (N-(2-pyridyl)oxamate): the copper(II) precursor [Me4N]2[Cu(opy)2].5H2O and CoII CuII coordination polymer {[CoCu(opy)2]}n×4nH2O. This latter compound was obtained by reaction of [Me4N]2[Cu(opy)2].5H2O and CoCl2.6H2O in water. The heterobimetallic CoII CuII chain was characterized by elemental analysis, IR spectroscopy, thermogravimetry and magnetic measurements. Magnetic characterization revealed typical behavior of one-dimensional (1D) ferrimagnetic chain as shown in the curves of temperature (T) dependence of magnetic susceptibility (χM), in the form of χMT versus T, and dependence of magnetization (M) with applied field (H).

OBJETIVO: Avaliar o efeito da cirurgia de revascularização miocárdica (CRM) sobre episódios isquêmicos assintomáticos (EIA). MÉTODOS: Foram estudados 28 homens, com angina estável (idade média 57,3±9,6) anos sem condições relacionadas a alterações de microcirculação e que, após retirada da medicação, apresentaram EIA à eletrocardiografia ambulatorial (ECGA). No pré-operatório e 4 meses após a cirurgia foram analisados os comportamentos dos EIA, segundo sua freqüência, e o de suas freqüências cardíacas (FC). A revascularização miocárdica foi completa em 75% dos casos. RESULTADOS: O número dos EIA foi reduzido de 162 (9 sintomáticos) no pré-operatório para, apenas, 4 no pós-operatório (p<0,05). Nos dois pacientes com EIA no operatório, estudo cinecoronariográfico confirmou obstrução de enxertos aortocoronários. A análise das FC no início e pico dos EIA sugeriram envolvimento de mecanismo de redução de oferta e aumento de consumo de oxigênio pelo miocárdio. CONCLUSÃO: A CRM eliminou os episódios isquêmicos relacionados ou não ao aumento da FC. Quando os EIA encontram-se presentes após CRM, devemos considerar a possibilidade de oclusão de enxerto.

PURPOSE: To evaluate the effect of coronary artery bypass graft surgery (CABG) on ischemic asymptomatic episodes (IAE). METHODS: Twenty eight males (mean age 57.3±9.6 years) with stable angina and no microcirculation abnormalities, who presented with IAE after medication withdrawal, were studied using ambulatory electrocardiography monitoring. Presence of IEA was analyzed before and 4 months after CABG according to its frequency and heart rate (HR) response. CAGB was considered complete in 75% of the cases. RESULTS: The number of IAE was reduced from 162 (9 symptomatic) in the preoperative period to 4 after surgery (p<0.05). In two patients with IAE in the postoperative period, coronariography confirmed obstruction of aortocoronary grafts. Analysis of HR at the beginning and peak of IAE suggested as mechanisms both reduced blood flow and increased oxygen consumption by the myocardium. CONCLUSION: CABC eliminated IAE regardless of HR. When IAE is present after surgery, graft occlusion should be suspected.

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

Analisou-se a epidemia de calazar ocorrida no Estado do Piauí, no período de 1980-1986. Os dados foram coletados pela SUCAM-Piauí, órgão do Ministério da Saúde para o controle de endemias, pela busca ativa na rede de assistência à saúde do Estado. A epidemia iniciou-se em municípios do centro e do norte, em 1980. No interior, ao contrário do período endêmico, quando predominou em áreas de maior altitude e clima semi-árido, a epidemia grassou nos vales de rios e em região mais úmida, de clima tropical. A capital do Piauí, Teresina, foi atingida em 1981, com pico epidêmico em 1984 e tendo sido responsável por mais de 60% dos 1.509 casos de todo o Estado. Foram feitas tentativas de controle pelo uso intensivo de inseticidas e eliminação de cães. Nas outras regiões do Piauí, borrifadas intensivamente para o controle da doença de Chagas e da malária, a epidemia foi pouco importante e cedeu espontaneamente. Nem a casuística e nem a população flebotomínica de Teresina apresentaram variações sazonais significativas, mas estiveram moderadamente correlacionadas entre si. Houve maior prevalência em menores de cinco anos, principalmente nos anos de maior incidência, e menor em maiores de 40 anos. A distribuição geográfica do processo epidêmico e a concomitância de seu início com seca prolongada acompanhada de emigração de pessoas e animais domésticos procedentes de regiões endêmicas para aquelas epidêmicas, sugerem que estes movimentos migratórios desencadearam a epidemia. O fato de o processo epidêmico ter cedido espontaneamente em áreas onde não se tentou o seu controle indica que não se pode atribuir apenas às medidas de controle o fim da epidemia. A partir da análise dos coeficientes de incidência específicos por faixa etária, é discutida a possiblilidade da progressiva redução na proporção de suscetíveis, determinada tanto por um grande número de infecções assintomáticas como pela ocorrência de imunidade duradoura, ter contribuído para a extinção da epidemia.

The kala-azar epidemic in the State of Piauí 1980-1986 is analyzed on the basis of the data collected by SUCAM Piauí. The outbreak began in towns of central and northern Piauí in 1980. In contrast what has happened in endemic periods in which the disease occurred in areas of higher altitude and semi-arid climate, the epidemic developed in humid tropical river valleys in rural zones. The epidemic was worst in the towns. The state capital, Teresina, hit in 1981, reached the epidemic peak in 1984 and accounted, for more than 60% of the 1,509 cases in the state. The epidemic was not substantial in those regions sprayed to combat malaria and Chagas' disease. While control in Teresina was attempted through intensive use of insecticides, the outbreak gave way spontaneously in rural areas. Neither the number of cases nor the phlebotomine population of Teresina presented significant seasonal variations but were moderately correlated. There was greater prevalence in children of 5 years of age or less, especially during the peak epidemic years, and much lesser prevalence in adults over 40 years of age. The geographical distribution of the epidemic process and its beginning, concommitant with a prolonged drought with its accompanying migration of people and domestic animals from endemic to epidemic regions, suggests that migration unleashed the epidemic. The fact that the epidemic process spontaneously relinquished its hold in areas where no control was attempted, indicates that the end of the epidemic cannot be attributed solely to measures of control. An analysis of the coefficients of specific incidence within age groups sparks the discussion about the possibility that progressive reduction of susceptibility (determined by the great number of assymptomatic infections as well as by long-lasting immunity) contributed to the extinction of the epidemic.

Êste trabalho estuda estatísticamente dados sôbre café rebeneficiado por cooperativas de cafeicultores do Estado de São Paulo. Seis cooperativas foram estudadas, com um total de 289 partidas de café. Em cada partida se determinou a média ponderada, do número de defeitos, antes e depois do rebeneficiamento. As raízes quadradas dos dados assim obtidos é que foram analisados. Melhoria estatisticamente significativa do tipo do café foi comprovada em tôdas as cooperativas, com uma única exceção, referente à Cooperativa da Média Sorocabana, onde a diminuição do número de defeitos não atingiu o nível de significância. Esta exceção da Cooperativa da Média Sorocabana provàvelmente se deve às seguintes razões: a) Apenas 7 partidas de café foram beneficiadas. b) A Cooperativa, ainda nova, não dispunha ainda de equipamento completo. Resultados excelentes foram obtidos, por exemplo, na Cooperativa dos Cafeicultores da Alta Mogiana, onde a diferênça observada foi significativa ao nível de 1% de probabilidade. As médias foram as seguintes: Média das raízes quadradas dos números de defeitos antes do rebeneficiamento = 7,81 ± 0,21. Média das raízes quadradas dos números de defeitos depois do rebeneficiamento = 3,53 ± 4,21. Estas médias correspondem a 61 defeitos para o café antes do rebeneficiamento, e 12 depois dêle.

This paper deals with the statistical analysis of data referring to raw coffee processed by cooperatives in the State of São Paulo, Brasil. Six cooperatives were studied, with a total 289 batches of coffee for all of them. For each batch the weighted average of defects was determined, before and after processing. The square roots of the data thus obtained were submitted to the technique of analysis of variance. Significant improvement in coffee type was proved in all cases, with only one exeption. The exception ocurred for the "Cooperativa da Média Sorocabana", where observed improvement was not statistically significant, this being probably due to tre following reasons: a) data of only 7 batches were available; b) the cooperative is new, and had not yet all the equipment needed. Excellent results were obtained, for example, in the "Cooperativa dos Cafeicultores da Alta Morgiana", were a difference significant at the 1% level of probability was observed, with the following means of square roots of defects and standard errors of the mean: Average number of defects before processing = 7.81 ±0.21. Average number of defects after processing = 3.53 ± 0.21. This mans that the average number of defects was lowered from aproximately 61, before processing, to 12, after processing.
