Characterization of the oral fungal microbiota in smokers and non‐smokers

This study aimed to assess the effect of smoking on the biodiversity of the oral fungal microbiota of healthy young subjects, using an improved culture method that assesses both total and pathogenic viable fungi. Forty individuals (20 smokers and 20 non‐smokers) were selected. All individuals presented fungal growth (100% for molds and 92.5% for yeasts), a prevalence higher than previously reported. The most commonly occurring molds were Penicillium sp., Aspergillus sp., and Cladosporium sp. Smokers presented significantly higher levels of yeasts and pathogenic molds than did non‐smokers. No differences in fungal prevalence and diversity were observed in smokers and non‐smokers following a 30‐wk observation period. In conclusion, tobacco smoking may alter the oral mycobiota and facilitate colonization of the oral cavity with yeasts and pathogenic molds. The effect of chronic fungal colonization on the oral health of tobacco smokers cannot be neglected.     

Geoprocessing in health area

The map's usage and the concerns about geographic distribution related with diseases are not a recent issue. A classical example is the John Snow survey -maps were used to locate cholera's cases and related them with the water supplying. The spatial representation techniques are fewer used in health sectors due to troubles in managing such information. So, the aim of this survey was to establish the disease spatial distribution in Ribeir?o Preto, 2002. Secondary data were used to elaborate this study. The spatial distribution of cases was realized by using the MapInfo 7.8 software. Although many cases were concentrated in the northeast region in the city, which consists the quarters of low economical income. The results contribute to show the Tb spatial distribution in Ribeirao Preto, they also reinforce the space category as a methodological alternative to manage, to monitor and to evaluate the health actions by directing interventions to decrease the iniquities.     

Intra- and extra-thymic expression of the pre-T cell receptor α gene

We have analyzed pre-T cell receptor α (pTα) gene expression in cells from various anatomical sites to investigate the lineage specificity of pTα RNA as well as its presence in pro-T cells and in sites of extrathymic T cell development. pTα RNA is found in precursors of αβ T cells but is absent from mature αβ T cells as well as T cells that express the γδ T cell receptor on the cell surface. pTα expression is exquisitely T lineage specific in that mature and immature B cells, myeloid cells, NK cells and pluripotent stem cells are pTα negative. On the other hand, pTα expression is found in pro-T cells outside the thymus as well as in intra- and extra-thymic sites of T cell development. The latter finding is consistent with the notion that early steps of T cell development within and outside the thymus may be similar.     

Unveiling the daily experience of the hospitalized adolescent

My experience in the adolescence was marked by the hospitalization process. Currently, as a nursing professional that take care of hospitalized young, there arose inquietudes that originated this study. The investigation object was the significance of the hospitalization in the adolescence, having as objective to understand this significance for the hospitalized adolescent. It was used the qualitative approach in the light of the Martin Heidegger's existential phenomenology. The setting was a specific internment unit for adolescents and the deponents were hospitalized young. This study made possible to understand that the adolescent unveiled himself as a being-with and understand of himself as a being--in the--world thrown to the death. The research pointed to the need of a real implementation of the public policies addressed to the hospitalized adolescent.     

Nursing: the meaning of this profession to nurses. A first approach

In an attempt to understand, tell and, why not, participate a little in the history of Nursing, we proposed to study the prejudices and negative stereotypes that have permeated this profession over time. This is a before-after experimental type of study in a population of adolescents regularly enrolled in the eleventh grade of a Brazilian public school. The intervention took the form of a lecture about the profession and a questionnaire with closed questions which was applied before and after the lecture. Conclusions were based on the results of binomial and McNemar's non-parametric tests for the significance of changes. Although the statistically significant presence of prejudice and negatives stereotypes was not found, the results of the intervention were in line with expectations, since the changes(or tendency towards changes) took place exactly in those subgroups that showed a greater frequency of stereotypes.     

Cultural adaptation to Brazil of the questionnaire Costs of caring for children with cancer

OBJECTIVE:

to present the cultural adaptation of the questionnaire Costs of caring for children with cancer, offering a valid and reliable tool to assess the economic repercussions of childhood cancer for Brazilian families.

METHOD:

it is a methodological research with a cross-sectional design. The methodological framework to validate the questionnaire was a combined process that included seven steps: translation to Portuguese; first translated consensus version; evaluation by Expert Committee; consensus on the Expert Committee version; back-translation; consensus of back-translated versions; semantic validation. The study was conducted in two phases: phase one was the translation and back-translations process, with five expert committee members. Phase two was the semantic validation, with 24 participants, who answered an instrument about their impressions of the questionnaire and suggested modifications.

RESULTS:

in phase one, items were included, excluded, and replaced to make the content equivalent and valid for use with Brazilian context. In phase two, the majority of the participants were mothers, who made suggestions about the relevance and clarity of the items in the questionnaire.

CONCLUSIONS:

the authors discussed these recommendations and made adaptations, turning the questionnaire into a valid and reliable tool for application.
