Respiratory problems represent one of the main morbidity causes in children in practically all of Brazil, with air pollution being one of the chief causes. This work was intended to evaluate the association between the number of hospital admissions for respiratory problems in children and the concentration of suspended particulate material in suspension in the town of Divinópolis, Minas Gerais State, in the period from 2000 to 2006. The methodology used was that of the descriptive and exploratory non-experimental research, characterizing itself in a retrospective study. It was found that during the investigated period, respiratory disturbances reached the top position in hospitalizations in public hospitals, corresponding to the main cause of admission and representing one third of all admissions over that period. The analysis of the data stressed an inverse ratio between the concentration of particulates in air and meteorological change. The data show further that there is a direct relationship between the concentration of particulates in the atmosphere, air quality and the epidemiologic picture, the latter pictured by the number of hospital admissions of children for respiratory diseases.

Polycyclic aromatic hydrocarbons (PAH) are carcinogenic to humans and can be found in various environments. This paper describes a cold fiber (CF) solid-phase microextraction (SPME) sampling method with gas chromatography mass spectrometry (GC/MS) to identify 16 PAH in spring water. The method yields good results for some validation parameters. The LOD and LOQ ranged from 7.10 to 57.96ngL-1 and from 23.60 to 193.19ngL-1, respectively. The intra-assay precision shows a coefficient of variation (CV) ranging from 4.38 to 17.65%, and recovery tests varied from 76±13% to 99±8%. The proposed method was attractive, as it extracted higher amounts of PAH in a single extraction procedure in comparison with conventional approaches. The method was applied to the analyses of PAH in twenty-four spring water samples collected in Divinópolis City, Minas Gerais, Brazil. Average PAH concentrations were in the range of 62.80±10.40ngL-1 for Benzo[a]anthracene and 146.58±98.98ngL-1 for Benzo[a]pyrene. © 2013 Elsevier B.V.

The aim of this article is to identify the social representations of the users of operative groups about health and the physical therapy role in the health/disease process, as well as to verify how the representations of the users are related to the purposes of these groups. The present study was developed under a qualitative approach using the semi-structured interview. Users of the "Quality of Life" project from four basic health units of the city of Divinópolis, Minas Gerais State, were interviewed. The interviews were recorded and transcribed in order to preserve the totality of the statements. The analysis of the data was performed based on the thematic units. The main themes that emerged were: health as absence of disease, dependency of the group, physical therapy linked to physical rehabilitation and to health promotion, physical therapy linked to the psychological improvement and humanization of the physical therapy assistance. The knowledge of the social representations of the users from the "Quality of Life" project reinforces the need of the participation of the population in the development, accomplishment and evaluation of the health programs in order to reach coherence between the user expectations and the purposes of the program.

Stretching is used to modify muscle length. However, its effects seem to be temporary. There is evidence in animal models that strengthening in a lengthened position may induce long lasting changes in muscle length. The objective of this study was to compare changes in hamstrings flexibility, peak torque angle and stretch tolerance after two training programs: stretching and strengthening in a lengthened position. Forty-five subjects with tight hamstrings were randomly assigned into three groups: control, stretching and strength training in lengthened position. The interventions were performed three times a week for eight weeks. The subjects were assessed before and after the end of the programs. Data provided by an isokinetic dynamometer were used to assess hamstrings flexibility, peak torque angle, and stretch tolerance. The data analysis demonstrated that strengthening in lengthened position changed peak torque angle in the direction of knee extension (p=0.001). No change in flexibility was observed (p=0.449). Both experimental groups showed an increase in stretch tolerance (p=0.001). The results demonstrated that strengthening in a lengthened position produced a shift of the torque-angle curve, which suggests an increase in muscle length. Conversely, stretching did not produce modification of torque-angle curve and flexibility; its effects appear restricted to increases in stretch tolerance.
