Short Assessment of Health Literacy for Portuguese-speaking Adults

OBJECTIVE: To develop and validate a short health literacy assessment tool for Portuguese-speaking adults. METHODS: The Short Assessment of Health Literacy for Portuguese-speaking Adults is an assessment tool which consists of 50 items that assess an individual's ability to correctly pronounce and understand common medical terms. We evaluated the instrument's psychometric properties in a convenience sample of 226 Brazilian older adults. Construct validity was assessed by correlating the tool scores with years of schooling, self-reported literacy, and global cognitive functioning. Discrimination validity was assessed by testing the tool's accuracy in detecting inadequate health literacy, defined as failure to fully understand standard medical prescriptions. RESULTS: Moderate to high correlations were found in the assessment of construct validity (Spearman's coefficients ranging from 0.63 to 0.76). The instrument showed adequate internal consistency (Cronbach's alpha=0.93) and adequate test-retest reliability (intraclass correlation coefficient=0.95). The area under the receiver operating characteristic curve for detection of inadequate health literacy was 0.82. A version consisting of 18 items was tested and showed similar psychometric properties. CONCLUSIONS: The instrument developed showed good validity and reliability in a sample of Brazilian older adults. It can be used in research and clinical settings for screening inadequate health literacy.

Cross-cultural validity of the demand-control questionnaire: Swedish and Brazilian workers

OBJECTIVE To evaluate the cross-cultural validity of the Demand-Control Questionnaire, comparing the original Swedish questionnaire with the Brazilian version. METHODS We compared data from 362 Swedish and 399 Brazilian health workers. Confirmatory and exploratory factor analyses were performed to test structural validity, using the robust weighted least squares mean and variance-adjusted (WLSMV) estimator. Construct validity, using hypotheses testing, was evaluated through the inspection of the mean score distribution of the scale dimensions according to sociodemographic and social support at work variables. RESULTS The confirmatory and exploratory factor analyses supported the instrument in three dimensions (for Swedish and Brazilians): psychological demands, skill discretion and decision authority. The best-fit model was achieved by including an error correlation between work fast and work intensely (psychological demands) and removing the item repetitive work (skill discretion). Hypotheses testing showed that workers with university degree had higher scores on skill discretion and decision authority and those with high levels of Social Support at Work had lower scores on psychological demands and higher scores on decision authority. CONCLUSIONS The results supported the equivalent dimensional structures across the two culturally different work contexts. Skill discretion and decision authority formed two distinct dimensions and the item repetitive work should be removed.

Paracoccidioides cerebriformis Moore, 1935. MYCOLOGIC AND IMMUNOCHEMICAL STUDY

The present study concern on mycologic and immunochemical data obtained from two samples of a fungus considered as belonging to the species Paracoccidioides cerebriformis described by Moore in 1935, and maintained since then on Sabouraud’s agar in the mycology collection of the Instituto de Medicina Tropical de São Paulo. After 60 years, the samples exhibited the same characteristics described by Moore (1935). However, experimental lesions did not resulted in guinea-pigs inoculated intratesticularly. The dominant antigen in Paracoccidioides brasiliensis, 43 kDa glicoprotein (gp43), could not be demonstrated by SDS PAGE and Western blotting. Immunoelectrophoresis did not demonstrated the E arch of cathodic migration using a policlonal anti gp43 serum. According to these findings, it is concluded that the fungus described by Moore (1935) as P. cerebriformis does not belong to the genus Paracoccidioides. Paracoccidioidomycosis should therefore be considered as resulting from infection by a single species, Paracoccidioides brasiliensis (Splendore, 1912) as asserted by Almeida (1930). Further studies, through molecular biology methods, could identify the mentioned fungus

A peste no nordeste oriental do Brasil e sua fitofisionomia geográfica no período de 1935-1967

Neste trabalho foram realizados estudos sôbre a distribuição da peste no Nordeste Oriental do Brasil, relacionando-se esta endemia com as zonas fitofisionômicas. Os dados aqui utilizados foram acumulados do período de 1935 a 1967. O autor faz ainda considerações sôbre a teoria da focalidade e conclui que a peste, dentro do conceito ecológico, deve ser considerada como uma doença euritópica.

Projeto Flora Amazônica: eight years of binational botanical expeditions

A review of the history and results of the first eight years of fieldwork of Projeto Flora Amazônica is given. This binational plant collecting program, sponsored by the Conselho Nacional de Desenvolvimento Científico e Tecnológico and the National Science Foundation, has mounted 25 expeditions to many parts of Brazilian Amazonia. Expeditions have visited both areas threatened with destruction of the forest and remote areas previously unknown botanically. The results have included the collection of 32,976 members of vascular plants, 16, 482 of cryptogams, as well as quantitative inventory of 18.67 hectares of forest with the collection of 7,294*** numbers of sterile vouncher collections. The non-inventory collections have been made in replicate sets of 10-13 where possible and divided equally between Brazilian and U.S. institutions. To date, 55 botanists from many different institutions and with many different specialities have taken part with 36 different Brazilian botanists. The resulting herbarioum material is just beginning to be worked up and many nem species have been collected as well as many interesting range extensions and extra material of many rare species.

ESTRATÉGIA REPRODUTIVA E ALGUNS ASPECTOS DEMOGRÁFICOS DO CAMARÃO Palaemonetes carteri GORDON, 1935 NA AMAZONIA CENTRAL, RIO NEGRO

A ecologia do camarão Palaemonetes carteri Gordon, 1935 (Decapoda: Palaemonidae) foi estudada através de coletas mensais, realizadas de janeiro 1989 até maio 1990, na região de Manaus. P. carteri vive na liteira submersa dos igarapés de terra firme em áreas baixas inundadas periodicamente pelas enchentes dos rios. A estratégia de reprodução e a dinâmica da razão sexual foram estudados na base dos 4,441 indivíduos coletados. P. carteri mostrou um dimorfismo sexual do comprimento, as fêmeas sendo maiores que os machos. O período de reprodução foi restrito a enchente e a cheia das águas. O número de ovos por fêmea variou entre 5 e 39, sem nenhuma correlação com o tamanho das fêmeas. A razão sexual mostrou uma predominância de fêmeas sem nenhuma variação sazonal significativa.

Distribuição de Paravelia recens (Drake & Harris, 1935) (Hemíptera, Heteroptera, Veliidae) em Guzmania brasiliensis Ule, 1907 (Bromeliaceae) na Reserva Florestal Adolpho Ducke, Amazonas, Brasil

Este é o primeiro registro de Paravelia recens (Drake & Harris, 1935) (Heteroptera: Veliidae) em fitotelmata de Guzmania brasiliensis Ule, 1907 (Bromeliaceae). O estudo foi conduzido na Reserva Florestal Adolpho Ducke, localizada na rodovia AM 010 km 26, Manaus, Amazonas. Foram realizadas doze amostragens, entre abril de 2003 e abril de 2005, seis no período chuvoso e seis no período de seca. Para cada amostragem, 12 bromélias foram analisadas, seis terrestres e seis epífitas, totalizando 144 amostras. Com exceção das amostras de março e outubro de 2004, 94 espécimes de P. recens foram encontrados. O número de indivíduos coletados foi semelhante nos estratos amostrados, sendo 46 terrestres e 48 epífitas. No período chuvoso foi encontrado um maior número de P. recens (teste-t entre períodos; t =2,57; p=0,011), assim como a abundância de indivíduos esteve positivamente correlacionada com o volume de água por bromélia (r s= 0,18; p=0,033). Este fato pode ser explicado pelo maior aporte de água no período chuvoso acarretando o aumento do volume médio de água nas bromélias.

Notas de ixodologia: III - conformação de Ixodes aragãoi Fonseca, 1935, de Ixodes amarali Fonseca, 1935, e lista das espécies do gênero Ixodes que ocorrem no Brasil (Acari, Ixodidae)

After comparison of the types of Ixodes ricinus aragãoi Fonseca, 1935, with a lot of Ixodes affinis Neumann, 1899, kindly loaned by Dr. Kohls, it was observed that both species differ by the aspect of the dorsal scutm, no large punctations being in the posterior border in the Brazilian material. Therefore is FONSECA'S species maintened as Ixodes aragãoi Fonseca, 1935. Ixodes amarali Fonseca, 1935 was reexamined and confirmed as a valid species. A list of Brazilian species of the genus Ixodes studied by the authors is presented.

Contribution to the knowledge of Philometra lateolabracis Yamaguti, 1935 (Nematoda, Filarioidea)

In this paper the authors refere Philometra lateolabracis Yamaguti, 1935 for the first time from the Atlantic Ocean also as a new host record. They report the rpesence of one male of diminished dimensions, found in close relationship with the females of Ph. lateolabracis; as the male of this species is unknown, they admit the possibility of this small nematode be the male of this species.
