This is a qualitative and descriptive study, which aimed to identify the occupational risks of a shoe industry, as well as the preventive measures taken against those risks, from the workers' perspective. The sample consisted of fifteen workers. Data were collected through semi-structured interviews and analyzed according to content analysis. The ethical aspects were respected and the research was approved by the Committee of Ethics in Research of the Northwest Regional University of Rio Grande do Sul. The results showed that the workers are aware of the risks of their work process, made use of safety measures for personal protection, and the company offers safety devices, informing and performing periodical visits to the sectors, aiming to develop educational actions.

Introduction: Benzodiazepines are among the most prescribed drugs for anxiety and one of the most used drug classes in the world and have a high potential for addiction. The objective of this study was to assess levels of dependence and anxiety among users of these drugs in the public health system. Methods: This was a cross-sectional, descriptive and quantitative study. Benzodiazepine users treated on the public health system were selected. Anxiety levels were assessed with the Hamilton Anxiety Scale and dependency with the Benzodiazepine Dependence Self-Report Questionnaire. Results: Benzodiazepine use was higher among women and in older age groups. Duration of benzodiazepine use was greater than 1 year for all respondents. The dependence assessment indicated that more than half of users were dependent on taking benzodiazepines and most had a severe degree of anxiety. Conclusion: This study found evidence of prolonged and inappropriate use of benzodiazepines. It is necessary to educate users about the risks of these drugs and to develop strategies to rationalize use of these drugs by working with prescribers and dispensers. © 2016, Sociedade de Psiquiatria do Rio Grande do Sul.

The present article is the result of a bibliographical survey that seeks to present, by using a methodology based on the hypothetical-deductive method, to present a reflection on the biotechnological advances taking in consideration the vulnerability of the individuals submitted to researches involving human beings in Latin America, especially regarding the limitations of health professionals' actions and their liability. The basis of this works is the assumption that it is impossible to separate science from ethics. For this work's purposes we consider health professionals to be everyone involved in scientific investigations, from the scientist responsible for the initial project to the members of the Ethics Committees which have the power either to approve or not research projects. It has been noticed that recent social developments created a great number of documents aiming at establishing boundaries to the actions of health professionals in the biomedical investigation field, documents which however have showed themselves incapable of protecting the rights of the individuals involved. The conclusion extracted from the present research is that health professionals must have their actions guided and limited by the Ethics Codes related to their professional areas but also that there must be a legal regulation that takes into account the diversity and vulnerability of Latin Americans in order to make possible holding referred professionals liable and thus protecting the individuals involved.

Mate (Ilex paraguariensis A. St. Hil.) is a raw material used to prepare popular beverages in South America, whose healthy effects have been pointed out. The leaves and stems of mate contain a complex assemblage of saponins, mainly ursolic acid and oleanolic acid glycosides, and their quantification presents difficulties such as weak cromophorous sites and interference of other compounds. On the other hand, the sugar moieties are a chief character that distinguishes them. We developed and validated a high-performance liquid chromatography method using a refractometer detector for quantifying the major saponins in extractive solution of mate leaves. The validation indicates the suitability of the method, presenting linearity in the concentration range between 102.5 to 854.0 microg/mL to matesaponin 1 and between 103.0 to 515.0 microg/mL to matesaponin 3. The repeatability coefficient of variation was 4.70% and 6.61% for matesaponin 1 and matesaponin 3, respectively. The inter-day coefficient of variation was 6.77% and 7.79% for matesaponin 1 and matesaponin 3, respectively. The analysis of plants from Brazilian States Mato Grosso do Sul and Rio Grande do Sul showed the predominance of matesaponins 1, 2, and 3 in the corresponding extractive solution. The sum of these three saponins ranged between 3 and 10 mg/g for mature leaves in the majority of sampled plants.

Cardiovascular diseases are the leading cause of death and disability in the elderly. In this study, healthy eating habits and associated factors in the prevention of cardiovascular disease in elderly hypertensive individuals were identified. It involved a cross-sectional study gathering primary data in a family health unit in a city in the interior of the state of Rio Grande do Sul and 212 elderly hypertensive individuals participated in the study. A higher prevalence among the lower age bracket of elderly individuals, female, with little schooling and low income was revealed. Healthy eating habits among the elderly hypertensive individuals assessed are below those recommended in the prevention of cardiovascular disease. Social and economic factors, health characteristics and the use of health services influenced the adoption of healthy eating habits. The results of this study suggest that elderly hypertensive individuals find it difficult to adopt healthy eating habits. This contributes further to the definition of strategies for routine prevention and control of cardiovascular diseases in the elderly.
