ABSTRACT
Abstract The little owl Athene noctua (Scopoli, 1769) is a small raptor that is widely distributed from northern to southern Portugal and several other countries in Europe, Asia and North Africa, and which has been introduced into New Zealand. In the current study, 18 fecal samples were collected from little owls kept at the Lisbon Center for Wild Animal Recovery, which is located in Monsanto Forest Park, Lisbon, Portugal. Twelve (67%) of them were found to be passing an undescribed species of Avispora in their feces. The oocysts of Avispora mochogalegoi n. sp. were ellipsoidal with a bilayered wall and measured 38.9 × 32.9 µm, with a shape index of 1.18. No micropyle, oocyst residuum or polar granule was present. The sporocysts were subspherical, measuring 21.1 × 20.1 µm. Stieda, sub-Stieda and para-Stieda bodies were absent. The sporocyst residuum was composed of a compact subspherical mass of granules. This is the fourth species of Avispora reported in Strigiformes.
Resumo O mocho-galego Athene noctua (Scopoli, 1769) é uma pequena ave de rapina amplamente distribuída de norte a sul de Portugal, em vários países da Europa, Ásia e norte da África, e foi introduzida na Nova Zelândia. No presente trabalho, 18 amostras de fezes foram coletadas de mochos-galegos mantidos no Centro de Recuperação de Animais Silvestres de Lisboa, localizado no Parque Florestal de Monsanto, Lisboa, Portugal. Doze (67%) deles eliminaram uma espécie não descrita de Avispora em suas fezes. Os oocistos de Avispora mochogalegoi n. sp. foram elipsóides, com parede de dupla camada, medindo 38,9 × 32,9 µm, e índice morfométrico de 1,18. A micrópila, resíduo do oocisto e grânulo polar foram ausentes. Os esporocistos foram subesféricos, medindo 21,1 × 20,1 µm. Corpos de Stieda, substieda e parastieda foram ausentes. O resíduo do esporocisto foi composto de uma massa subesférica compacta de grânulos. Esta é a quarta espécie Avispora relatada em Strigiformes.

Abstract The common kestrel Falco tinnunculus Linnaeus, 1758, is a widespread raptor, native in Europe, Asia and Africa, and vagrant in the Americas. In the current work, 27 fecal samples were collected from common kestrels kept in the Lisbon Center for Wild Animal Recovery, located at Monsanto Forest Park, Lisbon, Portugal. Five (19%) of them were found to be passing an undescribed species of Caryospora in their feces. The oocysts of Caryospora peneireiroi n. sp. were ellipsoidal with a bilayered wall and measured 47.1 × 37.6 µm with a shape index of 1.25. No micropyle, oocyst residuum or polar granule was present. The sporocysts were subspherical, measuring 25.1 × 24.3 µm. Stieda, sub-Stieda and para-Stieda bodies were absent. The sporocyst residuum was composed of many homogenous globules scattered throughout the periphery of the sporocyst. This is the fourth caryosporan species reported from F. tinnunculus.
Resumo O peneireiro Falco tinnunculus Linnaeus, 1758, é uma ave de rapina com vasta distribuição geográfica, nativa da Europa, Ásia e África, e errante nas Américas. No presente trabalho, 27 amostras de fezes foram coletadas de peneireiros mantidos no Centro de Recuperação de Animais Silvestres de Lisboa, localizado no Parque Florestal de Monsanto, Lisboa, Portugal. Cinco (19%) deles eliminaram uma espécie não descrita de Caryospora em suas fezes.

Resíduo do esporocisto foi composto de muitos glóbulos homogêneos espalhados por toda a periferia do esporocisto. Essa é a quarta espécie Caryospora descrita de F. tinnunculus.

O Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) é uma coorte prospectiva multicêntrica de funcionários públicos delineada para avaliar os determinantes das doenças crônicas, principalmente a doença cardiovascular e o diabetes tipo 2. Neste artigo são descritos os principais pontos do delineamento e implementação do projeto do biobanco do ELSA-Brasil. São detalhados aspectos econômicos, políticos, logísticos e tecnológicos do estudo. O artigo também discute o protocolo final de estocagem de material biológico e as instalações implementadas para atingir esse objetivo. O processo de delineamento e implementação do biobanco do ELSA-Brasil durou três anos. Tanto os biobancos centrais quanto os locais foram constituídos de acordo com as melhores práticas de estocagem de material biológico, usando soluções tecnológicas diferentes para as diferentes necessidades previstas no estudo.
The Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) is a multicenter prospective cohort of civil servants designed to assess the determinants of chronic diseases, especially cardiovascular diseases and type 2 diabetes. The present article describes the main design and implementation points of the ELSA-Brasil biobank project. Economic, political, logistical and technological aspects of this study are characterized. Additionally, it discusses the final biorepository protocol and the facilities implemented to achieve this objective. The design and implementation process of the ELSA-Brasil biobank took three years to be performed. Both the central and local biobanks were built according to the best biorepository techniques, using different technological solutions for the distinct needs expected in this study.

O Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) é um estudo de coorte multicêntrico com o objetivo de identificar os fatores de risco associados ao diabetes tipo 2 e à doença cardiovascular na população brasileira. O artigo descreve as estratégias de coleta, processamento, transporte e de controle de qualidade dos exames de sangue e urina no ELSA. O estudo optou pela centralização dos exames em um único laboratório. O processamento das amostras foi realizado nos laboratórios locais, reduzindo o peso do material a ser transportado e diminuindo os custos do transporte para o laboratório central no Hospital da Universidade de São Paulo. O estudo incluiu exames para avaliação de diabetes, resistência à insulina, dislipidemias, alterações eletrolíticas, hormônios tireoidianos, ácido úrico, alterações de enzimas hepáticas, inflamação e hemograma completo. Além desses exames, foram estocados DNA de leucócitos, amostras de urina, plasma e soro. O laboratório central realizou aproximadamente 375.000 exames.
The ELSA (Estudo Longitudinal de Saúde do Adulto - Brazilian Longitudinal Study for Adult Health) is a multicenter cohort study which aims at the identification of risk factors associated with type 2 diabetes and cardiovascular diseases in the Brazilian population. The paper describes the strategies for the collection, processing, transportation, and quality control of blood and urine tests in the ELSA. The study decided to centralize the tests at one single laboratory. The processing of the samples was performed at the local laboratories, reducing the weight of the material to be transported, and diminishing the costs of transportation to the central laboratory at the Universidade de São Paulo Hospital. The study included tests for the evaluation of diabetes, insulin resistance, dyslipidemia, electrolyte abnormalities, thyroid hormones, uric acid, hepatic enzyme abnormalities, inflammation, and total blood cell count. In addition, leukocyte DNA, urine, plasma and serum samples were stored. The central laboratory performed approximately 375,000 tests.

DNA samples from blood and nasal swabs of 125 healthy household contacts was submitted to amplification by polymerase chain reaction (PCR) using a Mycobacterium leprae-specific sequence as a target for the detection of subclinical infection with M. leprae.All samples were submitted to hybridization analysis in order to exclude any false positive or negative results. Two positive samples were confirmed from blood out of 119 (1.7 percent) and two positive samples from nasal secretion out of 120 (1.7 percent). The analysis of the families with positive individuals showed that 2.5 percent (n = 3) of the contacts were relatives of multibacilary patients while 0.8 percent of the cases (n = 1) had a paucibacilary as an index case. All positive contacts were followed up and after one year none of them presented clinical signs of the disease. In spite of the PCR sensitivity to detect the presence of the M. leprae in a subclinical stage, this molecular approach did not seem to be a valuable tool to screen household contacts, since we determined a spurious association of the PCR positivity and further development of leprosy.
