Background: Being bullied has been increasingly recognized as a risk factor for the development of psychiatric disorders, but there is very limited evidence on the association of bullying with temperament. Methods: The data was collected in a large web-survey on psychological and psychiatric measures (BRAINSTEP). Bullying was assessed with a question on time exposed to bullying (none, <1 year, 1-3 years and >3 years) during childhood and adolescence. Emotional traits and affective temperaments were evaluated with the Affective and Emotional Composite Temperament Scale (AFECTS). The final sample consisted of 50,882 subjects (mean age 30.8±10.4 years, 73.4% females) with valid answers. Results: About half of the sample reported exposure to bullying and ∼10% reported being victimized by peers for longer than 3 years. Longer exposure to bullying was associated with lower Volition, Coping and Control scores, and more Emotional Sensitivity, Anger and Fear, with statistical significance between all groups. To a lower degree, exposure to bullying was associated with lower Caution and higher Desire scores. Bullying victimization was also associated with a much lower proportion of euthymic and hyperthymic types in both genders, which was compensated by an increase mainly in the proportion of depressive, cyclothymic and volatile types. Limitations: Retrospective assessment of bullying with a single question on time exposed to bullying and use of self-report instruments only. Conclusions: Being bullied was associated with a broad and profound impact on emotional and cognitive domains in all dimensions of emotional traits, and with internalized and unstable affective temperaments. © 2012 Elsevier B.V.

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.

Purpose of review Heat therapy, such as sauna and hot tub, has become an increasingly regular therapeutical practice around the world since several studies have shown benefits of heat therapy in metabolic and cardiovascular diseases. The use of heat therapy in people with type 2 diabetes mellitus revealed a striking reduction of 1% unit in the glycated hemoglobin, suggesting this therapy for the treatment of diabetes. Herein, we shall discuss the use of heat therapy and the mechanisms involved, and suggest a provisional guide for the use of heat therapy in obesity and diabetes. Recent findings Human studies indicate that heat therapy reduces fasting glycemia, glycated hemoglobin, body weight, and adiposity. Animal studies have indicated that nitric oxide and the increase in heat shock protein 70 expression is involved in the improvements induced by heat therapy on insulin sensitivity, adiposity, inflammation, and vasomotricity. Summary Heat therapy is a promising and inexpensive tool for the treatment of obesity and diabetes. We proposed that transient increments in nitric oxide and heat shock protein 70 levels may explain the benefits of heat therapy. We suggest that heat therapy (sauna: 80-100°C; hot tub: at 40°C) for 15 min, three times a week, for 3 months, is a safe method to test its efficiency. Copyright © 2015 Wolters Kluwer Health, Inc.

Objective: Diseases of the circulatory system are a principal cause of mortality in Brazil. Using as a basis drugs dispensed through Brazil's Popular Pharmacy Program (FPB, for its name in Portuguese), prices for drugs used to treat circulatory diseases were analyzed to identify the advantages of using generic drugs and the FPB. Methods: Drug prices were obtained using Brazil's Pharmacy Price Guide and FPB price tables. The costs of 15 drugs available through the FPB were compared with those of three generic pharmaceutical products, three similar products, and the reference drug. Results: The generic drugs were lower in price for 10 of the drugs and for four of the similar products. The FPB drugs were of the lowest price. Conclusions: Generic and FPB drugs are easily accessed by the population and thus facilitate the continuity of pharmacotherapy when these drugs are not available through the Unified Health System and/or are not affordable through other means. Access to drugs should be taken into consideration at the time prescriptions are filled, especially as regards those used to treat chronic diseases.

This paper addresses a new methodology for servo pneumatic actuators mathematical modeling and selection from the dynamic behavior study in engineering applications. The pneumatic actuator is very common in industrial application because it has the following advantages: its maintenance is easy and simple, with relatively low cost, self-cooling properties, good power density (power/dimension rate), fast acting with high accelerations, and installation flexibility. The proposed fifth-order nonlinear mathematical model represents the main characteristics of this nonlinear dynamic system, as servo valve dead zone, air flow-pressure relationship through valve orifice, air compressibility, and friction effects between contact surfaces in actuator seals. Simulation results show the dynamic performance for different pneumatic cylinders in order to see which features contribute to a better behavior of the system. The knowledge of this behavior allows an appropriate choice of pneumatic actuator, mainly contributing to the success of their precise control in several applications. © 2011 Antonio Carlos Valdiero et al.

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.

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.

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.
