Diagnóstico pré-natal
Pinto Júnior,Walter;
Ciência & Saúde Coletiva , 2002, DOI: 10.1590/S1413-81232002000100013
Abstract: this article contains all the methods for pré-natal diagnosis of genetic and chromosomal abnormalities, as well infectious diseases in pregnancy. the author discuss the difference among them and the new tools of molecular biology applied in these diagnoses. at the end there is a description of the technique of pre-implantation diagnosis and its use in vitro fertility laboratories distant as long as 2000 kilometers one from the other.

Abstract: O presente artigo apresenta uma descri o de todos os métodos de diagnóstico pré-natal de anormalidades genéticas e cromoss micas, bem como dos relativos a doen as infecciosas na gravidez. O autor discute as diferen as entre eles, e as novas ferramentas da biologia molecular que s o aplicadas nesses diagnósticos. Ao final é feita uma descri o da técnica de diagnóstico pré-implanta o e de seu uso in vitro em laboratórios de fertilidade situados a mais de dois mil quil metros um do outro.
Studies on Barlow points, Gauss points and Superconvergent points in 1D with Lagrangian and Hermitian finite element basis
Pinto Júnior, David Soares;
Computational & Applied Mathematics , 2008,
Abstract: in this work, we consider the superconvergence property of the finite element derivative for lagrange's and hermite's family elements in the one dimensional interpolation problem. we also compare the barlow points, gauss points and superconvergence points in the sense of taylor's series, confirming that they are not the same as believed before. we prove a not evident and new superconvergence property of hermite's basis as well which shows that the centroid is not only a superconvergent for u'hbut an o(h5) accuracy point.

Trabalho e saúde: a atividade da queima de resíduos tóxicos em fornos de cimenteiras de Cantagalo, Rio de Janeiro
Pinto Júnior,Afranio Gomes; Braga,Ana Maria Cheble Bahia;
Ciência & Saúde Coletiva , 2009, DOI: 10.1590/S1413-81232009000600008
Abstract: this study analyzes the work and health conditions through the discourse of the employees involved in the activity of toxic waste co-processing in cement kilns in cantagalo, rj. a qualitative approach was adopted using a semi-structured interview with 13 individuals. after analyzing the discourse, it was possible to observe relevant failures in the work process planning, in the identification of risks, in preventing diseases, in monitoring health impacts and to the environment, even their identification and notification to the competent authorities. the assimilation of the uncertainties of the process, favoring the interests of the entrepreneurs, has passed on the workers the burden of illness, rendered acceptable in that they deny clinical evidences. it is imperative to establish a broad debate involving public and private entities, the society in all its representations, confronting ethical, environmental and health issues to the interests of capital in order to set new guidelines for the process.
Does the use of paclitaxel or rapamycin-eluting stent decrease further need for coronary-artery bypass grafting when compared with bare-metal stent?
Lemos Júnior, Hernani Pinto de;Atallah, álvaro Nagib;
Sao Paulo Medical Journal , 2007, DOI: 10.1590/S1516-31802007000400010
Abstract: context and objective: the safety and efficacy of drug-eluting stents reduce the need for surgical revascularization. the objective of the present study was to investigate whether paclitaxel or rapamycin-eluting stent are effective in avoiding the need for coronary-artery bypass grafting. methods: this was a systematic review of the literature using the methodology of the cochrane collaboration. the type of study considered was controlled randomized trials; the type of intervention was drug-eluting or bare-metal stents; and the main outcome investigated was coronary-artery bypass grafting. results: the ten studies included in this systematic review did not show any statistically significant difference between the drug-eluting stents and the bare-metal stents with regard to the outcome of coronary-artery bypass grafting (confidence interval: 0.31 to 1.42). conclusion: the surgical revascularization rate was not reduced by the use of drug-eluting stents.
Cardiac resynchronization therapy in patients with heart failure: systematic review
Lemos Júnior, Hernani Pinto de;Atallah, álvaro Nagib;
Sao Paulo Medical Journal , 2009, DOI: 10.1590/S1516-31802009000100009
Abstract: context and objective: cardiac resynchronization therapy (crt) has emerged as the predominant electrical treatment strategy for patients on pharmacological therapy who present heart failure with wide qrs and low ejection fraction. the objective of this study was to investigate whether cardiac resynchronization therapy improved mortality and morbidity among patients with heart failure. methods: this was a systematic review using the cochrane collaboration's methodology. the online search strategy included the cochrane library, medline (medical literature analysis and retrieval system online), lilacs (literatura latino-americana e do caribe em ciências da saúde) and cardiology congresses from 1990 to 2006. the criteria for considering studies for this review were as follows:-types of studies: randomized controlled trials; types of interventions: cardiac resynchronization therapy compared with other therapies; types of participants: patients with heart failure with low ejection fraction and wide qrs; outcomes: death or hospitalization. results: seven trials met the selection criteria. the risk of death due to congestive heart failure was nonsignificant: relative risk (rr), 0.79; 95% confidence interval (ci): 0.60 to 1.03. there was an absolute risk reduction of 4% in all-cause mortality for the experimental group #&091;rr 0.70; ci: 0.60 to 0.83; number needed to treat (nnt) 25#&093;; sudden cardiac death showed a statistically significant difference favoring the experimental group, with absolute risk reduction of 1% (ci: 0.46 to 0.96; rr 0.67; nnt 100). there was an absolute risk reduction of 9% for hospitalization due to heart failure (rr 0.64; ci: 0.50 to 0.80; nnt 11) in the experimental group. conclusions: patients receiving crt had a significantly lower risk of hospitalization due to heart failure, but death rates due to heart failure were similar.
Comparison of methods to monitor populations of Alphitobius diaperinus (PANZER, 1797) (Coleoptera: Tenebrionidae) in poultry farm, Pelotas, RS, Brazil / Compara o de métodos para monitorar popula es de Alphitobius diaperinus (PANZER, 1797) (Coleoptera: Tenebrionidae) em granja avícola, em Pelotas, RS, Brasil

Abstract: Alphitobius diaperinus (PANZER, 1797) (Coleoptera: Tenebrionidae) it colonizes the substratum found at farms, growing up in high populations, causing sanitary problems with economical reflexes. In this work the comparative evaluation of monitoring methods was accomplished of A. diaperinus. The evaluations were made in a period of twelve months, in broiler barn of the Conjunto Agrotécnico Visconde da Gra a, in Pelotas - RS, Brazil, using traps of the type "tube" or of Arends and type "sandwich". The type sandwich trap was shown more efficient in the capture of larvae and adults of A. diaperinus. Alphitobius diaperinus (Panzer, 1797) (Coleoptera: Tenebrionidae) coloniza o substrato encontrado em granjas, criando-se em altas popula es, causando problemas sanitários com reflexos econ micos. Neste trabalho foi realizada a avalia o comparativa de métodos de monitoramento de A. diaperinus. As avalia es foram feitas em um período de doze meses, em galp o de poedeiras do Conjunto Agrotécnico Visconde da Gra a, em Pelotas - RS, Brasil, utilizando armadilhas do tipo “tubo” ou de Arends e tipo “sanduíche”. A armadilha do tipo sanduíche mostrou-se mais eficiente na captura de larvas e adultos de A. diaperinus.
