O objetivo deste trabalho foi avaliar a suscetibilidade de genótipos de videira à drosófila?da?asamanchada, Drosophila suzukii (Diptera: Drosophilidae), em bagas de uva intactas e em bagas infestadas após a ocorrência de puncturas, causadas pela oviposição da mosca?das?frutas sul?americana [Anastrepha fraterculus (Diptera: Tephritidae)] ou por danos mecânicos (alfinetes). Os experimentos foram realizados em laboratório, a 22±1°C, umidade relativa de 65±10% e fotófase de 12 horas. A suscetibilidade foi avaliada para 18 genótipos de videira, em bagas intactas submetidas às fêmeas de D. suzukii. O potencial de interação foi verificado em bagas de uva 'Italia', cuja epiderme foi danificada por puncturas de A. fraterculus ou por alfinete, em comparação a frutos de morango 'Albion'. As cultivares de Vitis labrusca 'Niagara Rosada' e 'Concord' não foram infestadas por D. suzukii, e cinco dos oito genótipos que foram infestados são cultivares melhoradas. A infestação de D. suzukii em bagas de uva 'Italia' com danos mecânicos, feitos com um alfinete ou pela oviposição de A. fraterculus, foi semelhante à de bagas íntegras. Há baixa adequação hospedeira de videiras a D. suzukii, mesmo com a presença de danos. As cultivares 'Benitaka', 'BRS Vitória' e 'BRS Morena' são as mais suscetíveis a D. suzukii.

Este trabalho foi conduzido na área abrangida pelo campus da Escola Superior de Agricultura Luiz de Queiroz da Universidade de São Paulo, no município de Piracicaba, Estado de São Paulo. Teve como objetivos, determinar a composição do gênero Anastrepha Schiner e verificar a associação das espécies de plantas hospedeiras, estabelecidas na área, com as espécies de Anastrepha. Foram examinadas 23.277 fêmeas de Anastrepha coletadas por meio de armadilhas McPhail e 18 espécies pertencentes a nove grupos de espécies foram registradas. Um total de 563 amostras de frutos pertencentes a nove famílias e, pelo menos, 23 espécies de plantas foi coletado em 47 estações de capturas. Foram identificadas 10.243 fêmeas e das 18 espécies de Anastrepha capturadas em armadilhas somente seis emergiram das amostras de frutos: A. bistrigata Bezzi, A. fraterculus (Wied.), A. obliqua (Macquart), A. pseudoparallela (Loew), A. serpentina (Wied.) e A. sororcula Zucchi. A. fraterculus infestou maior diversidade de frutos. Os hospedeiros preferidos de A. obliqua foram as espécies da família Anacardiaceae. A. pseudoparallela e A. serpentina infestaram exclusivamente Passifloraceae e Sapotaceae, respectivamente. A. fraterculus é registrada pela primeira vez em sapoti (Manilkara zapota L.) no Brasil.

Endosymbiotic bacteria of the genus Wolbachia are widespread among arthropods and cause a variety of reproductive abnormalities, such as cytoplasmic incompatibility, thelytokous parthenogenesis, male-killing, and host feminization. In this study, we used three sets of Wolbachia-specific primers (16S rDNA, ftsZ, and wsp) in conjunction with the polymerase chain reaction (PCR), cloning and sequencing to study the infection of fruit flies (Anastrepha spp. and Ceratitis capitata) by Wolbachia. The flies were collected at several localities in Brazil and at Guayaquil, Ecuador. All of the fruit flies studied were infected with Wolbachia supergroup A, in agreement with the high prevalence of this group in South America. Phylogenetic analysis showed that the wsp gene was the most sensitive gene for studying the relationships among Wolbachia strains. The Wolbachia sequences detected in these fruit flies were similar to those such as wMel reported for other fruit flies. These results show that the infection of Anastrepha fruit flies by Wolbachia is much more widespread than previously thought.

Among the organisms acting in the natural biological control of tephritids, members of the family Braconidae are the most active form of natural parasite, and in Neotropical regions, members of Opiinae are the main control agents of Anastrepha. The objective of this work was to discover the percentage of parasitism and the species of braconid associated with fruit trees growing in cities on the southern coast of Bahia. During the period of August, 2005 to March, 2008, hosts fruits of fruit flies from several plant species were collected and from the fruits the following species of Anastrepha were obtained: A. fraterculus, A. obliqua, A. bahiensis, A. serpentina, A. sororcula and A. zenildae. Of the total of 838 specimens of braconids, 21.36% were of the species Utetes anastrephae (Viereck), obtained from yellow mombin, carambola, guava, mango and pitanga; 4.42% were of the species Asobara anastrephae (Muesebeck) obtained from the fruits of the yellow mombin, carambola and guava, and only one example of Opius bellus Gahan (0.12%) that came from a guava sample. The species Doryctobracon areolatus (Szepligeti) (74.10%) was predominant and emerged from puparia from all the host fruits collected, probably due to the greater efficiency of this species in locating tephritid larvae. The mean percentage of parasitism by Anastrepha spp. was 4.45%.

Dentre os organismos que atuam no controle biológico natural dos tefritídeos, os representantes da família Braconidae constituem-se no mecanismo de parasitismo natural mais atuante, e na região Neotropical, representantes de Opiinae são os principais agentes de controle de Anastrepha. Este trabalho teve por objetivo conhecer a percentagem de parasitismo e as espécies de braconídeos associados às fruteiras cultivadas em municípios da região Litoral Sul da Bahia. No período de agosto de 2005 a março de 2008, coletaram-se frutos hospedeiros de moscas-das-frutas de diversas espécies botânicas, e dos frutos foram obtidas as seguintes espécies de Anastrepha: A. fraterculus, A. obliqua, A. bahiensis, A serpentina, A. sororcula e A. zenildae. Do total de 838 exemplares de braconídeos, 21,36% foram da espécie Utetes anastrephae (Viereck), provenientes de cajá, carambola, goiaba, manga e pitanga; 4,42% da espécie Asobara anastrephae (Muesebeck) obtidos dos frutos de cajá, carambola e goiaba, e apenas um exemplar da espécie Opius bellus Gahan (0,12%) que emergiu da amostra de goiaba. A espécie Doryctobracon areolatus (Szépligeti) (74,10%) foi predominante e emergiu dos pupários provenientes de todos os frutos hospedeiros coletados, provavelmente pela maior eficiência desta espécie em localizar as larvas dos tefritídeos. A percentagem média de parasitismo de Anastrepha spp. foi de 4,45%.

Acute disseminated encephalomyelitis (ADEM) is a widespread monophasic inflamatory disease affecting the central nervous system, that usually follows an infection or vaccination. In this study, we present an analysis of magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) and clinical aspects in four patients with clinical diagnosis of ADEM. The presence of MRI demyelinating lesions was crucial, but not in itself sufficient for definitive diagnosis. Clinical and MRI follow up, in order to exclude new lesions and to reevaluate the former ones, as well as CSF, were important for the differential diagnosis with other demyelinating diseases, particularly multiple sclerosis. In addition, we have shown that early treatment with methylprednisolone after the initial symptoms was effective for improving clinical manifestations as well as for reducing MRI lesions.

The purpose of this article is to introduce elements that allow building an interface between the academic research and the programs of basic education for youngsters and adults. It discusses contributions to these programs that can be found in the results of qualitative research studies. To this end, results of a five-year long project on teacher education are used, which aim was that of analyzing the interaction between teacher and student in youngster and adult literacy classes. The research project was conducted in natural contexts with the purpose of understanding a given social reality, and not of establishing general laws. Therefore, the credibility of its results was built through the observation of multiple contexts, and the gathering of data was made through various methods, from the perspective of several participants observed during a prolonged period of time. This empirical basis was used to evaluate recommendations contained in the report commissioned by Unesco to the International Literacy Institute for presentation at the World Forum on Education held in 2000 in Dakar. This report proposed that the continuous attendance of students to basic education programs is one of the great challenges of the new millennium. With respect to the problem of adult evasion from courses and programs, the article discusses the motivation and accessibility factors, pointed out in official documents as relevant factors to the success or failure of the programs.

OBJECTIVE: The intensive care unit is synonymous of high severity, and its mortality rates are between 5.4 and 33%. With the development of new technologies, a patient can be maintained for long time in the unit, causing high costs, psychological and moral for all involved. This study aimed to evaluate the risk factors for mortality and prolonged length of stay in an adult intensive care unit. METHODS: The study included all patients consecutively admitted to the adult medical/surgical intensive care unit of Hospital das Clínicas da Universidade Estadual de Campinas, for six months. We collected data such as sex, age, diagnosis, personal history, APACHE II score, days of invasive mechanical ventilation orotracheal reintubation, tracheostomy, days of hospitalization in the intensive care unit and discharge or death in the intensive care unit. RESULTS: Were included in the study 401 patients; 59.6% men and 40.4% women, age 53.8±18.0. The mean intensive care unit stay was 8.2±10.8 days, with a mortality rate of 13.5%. Significant data for mortality and prolonged length of stay in intensive care unit (p <0.0001), were: APACHE II>11, OT-Re and tracheostomy. CONCLUSION: The mortality and prolonged length of stay in intensive care unit intensive care unit as risk factors were: APACHE>11, orotracheal reintubation and tracheostomy.

INTRODUCTION: Subclinical hypothyroidism (SCH), defined as elevated concentrations of thyroid stimulating hormone (TSH) despite normal levels of thyroid hormones, is highly prevalent in Brazil, especially among women and the elderly. Although an increasing number of studies have related SCH to an increased risk of coronary artery disease and mortality, there have been no randomized clinical trials verifying the benefit of levothyroxine treatment in reducing these risks, and the treatment remains controversial. OBJECTIVE: This consensus, sponsored by the Thyroid Department of the Brazilian Society of Endocrinology and Metabolism and developed by Brazilian experts with extensive clinical experience with thyroid diseases, presents these recommendations based on evidence for the clinical management of SCH patients in Brazil. MATERIALS AND METHODS: After structuring the clinical questions, the search for evidence in the literature was initially performed in the MedLine-PubMed database and later in the Embase and SciELO - Lilacs databases. The strength of evidence was evaluated according to the Oxford classification system and established based on the experimental design used, considering the best available evidence for each question and the Brazilian experience. RESULTS: The topics covered included SCH definition and diagnosis, natural history, clinical significance, treatment and pregnancy, and the consensus issued 29 recommendations for the clinical management of adult patients with SCH. CONCLUSION: Treatment with levothyroxine was recommended for all patients with persistent SCH with serum TSH values > 10 mU/L and for certain patient subgroups.
