A new strategy for risk assessment of PM2.5-bound elements by considering the influence of wind regimes.

For regulatory purposes, air pollution has been reduced to management of air quality control regions (AQCR), by inventorying pollution sources and identifying the receptors significantly affected. However, beyond being source-dependent, particulate matter can be physically and chemically altered by factors and elements of climate during transport, as they act as local environmental constraints, indirectly modulating the adverse effects of particles on the environment and human health. This case study, at an industrial site in a Brazilian coastal city - Joinville, combines different methodologies to integrate atmospheric dynamics in a strategic risk assessment approach whereby the influence of different wind regimes on environmental and health risks of exposure to PM2.5-bound elements, are analysed. Although Joinville AQCR has been prone to stagnation/recirculation events, distinctly different horizontal wind circulation patterns indicate two airsheds within the region. The two sampling sites mirrored these two conditions and as a result we report different PM2.5 mass concentrations, chemical profiles, geo-accumulation, and ecological and human health risks. In addition, feedback mechanisms between the airsheds seem to aggravate the air quality and its effects even under good ventilation conditions. Recognizably, the risks associated with Co, Pb, Cu, Ni, Mn, and Zn loadings were extremely high for the environment as well as being the main contributors to elevated non-carcinogenic risks. Meanwhile, higher carcinogenic risks occurred during stagnation/recirculation conditions, with Cr as the major threat. These results highlight the importance of integrating local airshed characteristics into the risk assessment of PM2.5-bound elements since they can aggravate air pollution leading to different risks at a granular scale. This new approach to risk assessment can be employed in any city's longer-term development plan since it provides public authorities with a strategic perspective on incorporating environmental constraints into urban growth planning and development zoning regulations.

Reliability from Cronbach's alpha homogeneity and test-retest stability). Results In face and content validation, the tool showed good acceptance among the judges and the target audience. The final exploratory factor analysis model resulted in a seven-item scale, divided into three domains, with an explained variance of 71.4%, with Cronbach's alpha ranging from 0.50 to 0.88. For scale reliability, Pearson r and Spearman ρ showed high reliability (0.997 and 0.986). Conclusion The Brazilian version of Champion's Health Belief Model Scale provides good evidence of validity based on internal structure and is reliable. It may be used in Brazil to assess mammography compliance monitoring.

Assessment of dapagliflozin effect on diabetic endothelial dysfunction of brachial artery (ADDENDA-BHS2 trial): rationale, design, and baseline characteristics of a randomized controlled trial.

BACKGROUND: Endothelial dysfunction (ED) is a hallmark in type 2 diabetes mellitus (T2DM) that favor both atherogenesis and ischemia and reperfusion injury (IRI). Sodium-glucose-2 co-transporter inhibitors (SGLT2i) may hypothetically improve microvascular and macrovascular functions via a broad spectrum of mechanisms, being superior to traditional antidiabetic therapy such as sulfonylurea, even in subjects under equivalent glycemic control. Hence, the present clinical trial was designed to compare the effect of these two treatments on markers of arterial wall function and inflammation in T2DM patients as well as on the potential mediating parameters. METHOD AND RESULTS: ADDENDA-BHS2 is a prospective, single-center, active-controlled, open, randomized trial. Ninety-eight participants (40-70 years old) with HbA1c 7-9% were randomized (1:1, stratified by gender, BMI and HbA1c levels) to either dapagliflozin 10 mg/day or glibenclamide 5 mg/day on top of metformin. The primary endpoint was the change of flow-mediated dilation (FMD) after a 12-week period of treatment evaluated at rest and after IRI between dapagliflozin and glibenclamide arms. Secondary outcomes were defined as the difference between treatments regarding: plasma nitric oxide (NO) change after FMD, plasma isoprostane, plasma levels of vascular inflammatory markers and systemic inflammatory markers, plasma levels of adipokines, anthropometric measures, glucose control parameters, office and ambulatory BP control. Safety endpoints were defined as systolic and diastolic function assessed by echocardiography and retinopathy change. Serious adverse events were recorded. The study protocol was approved by the Independent Scientific Advisory Committee. CONCLUSION: The ADDENDA-BHS2 trial is an investigator-initiated clinical trial comparing the effect of dapagliflozin versus glibenclamide on several aspects of vascular function in high cardiovascular risk T2DM patients. Besides, a large clinical and biochemical phenotype assessment will be obtained for exploring potential mediations and associations.Trial registration Clinical trial registration: NCT02919345 (September, 2016).

Detection of Breast Cancer: Knowledge, Attitude, and Practice of Family Health Strategy Women.

In rural area, control of breast cancer is related to health promotion and early diagnosis, which includes knowledge, awareness, and stimulating behavioral change, emphasizing screening for disease. The present study was developed to assess the knowledge, attitude, and practice of rural women about early detection of breast cancer in the Primary Health Care Centre. This is a cross-sectional study in a Primary Health Care Centre with 243 rural women participating in the public health service. Data collection was made by a self-administered questionnaire which included sociodemographic characteristics, questions on breast cancer risk factors, screening, and diagnostic methods. Marks were attributed to each question and calculated for each section. Participants fell in three categories of knowledge, attitude, and practice: appropriate, regular and inappropriate. Knowledge, attitude, and practice of early detection methods were considered especially appropriate for those rural women with education and higher economic level, but inadequate responses to such methods were still significant. It is noted that there is still a significant number of rural women who do not have basic knowledge regarding early detection methods of breast cancer, contributing to the non-realization of these methods, as its advocates.

Labor, trabalho e ação: elementos pertinentes aos conceitos arendtianos em relatos autobiográficos de trabalhadores do setor de transportes / Labor, work, and action: relevant elements regarding Arendt’s concepts in autobiographical reports of workers from the transportation sector

A reflexão, junto à classe trabalhadora, sobre questões relacionadas à saúde no ambiente de trabalho, visando à criticidade e às ações que resultem no enfrentamento de seus problemas é um importante instrumento de mudança da realidade. O objetivo desta pesquisa exploratória é identificar elementos pertinentes aos conceitos arendtianos (labor, trabalho e ação) presentes no discurso de trabalhadores do setor de transportes participantes de um projeto de extensão universitária. A abordagem é qualitativa e a metodologia consiste em relato autobiográfico. As histórias dos trabalhadores foram gravadas em DVD e posteriormente transcritas. Para a análise, optou-se pela definição de categorias a priori (labor, trabalho e ação), uma vez que o marco teórico era a obra de Hannah Arendt. Como resultado, foram encontrados: insegurança alimentar, doenças crônicas não transmissíveis relacionadas ao conceito de labor; riscos ergonômicos e distúrbios psíquicos relacionados ao trabalho; e participação coletiva e inclusão digital como elementos da ação. Concluiu-se que conhecer, compreender e discutir essas três categorias para o incremento da reflexão acerca da saúde do trabalhador pode ser importante, uma vez que todas elas foram expressas nos relatos de vida, mostrando sua permanência e relevância na história de todos e de cada um...

Reflection, along with the working class, on health-related issues at the workplace, aiming at criticality and actions that result in facing its problems, is a significant instrument to change reality. The purpose of this exploratory research is identifying relevant elements with regard to Arendt’s concepts (labor, work, and action) observed in the discourse of workers from the transportation sector participating in a university outreach project. The approach is qualitative and the methodology is autobiographical account. Workers’ histories were recorded on DVD and then transcribed. For the analysis, we chose to define a priori categories (labor, work, and action), since the theoretical framework was Hannah Arendt’s work. As a result, we found: food insecurity, chronic noncommunicable diseases related to the concept of labor; ergonomic hazards and psychic disorders related to work; and collective participation and digital inclusion as elements of action. It was concluded that knowing, understanding, and discussing these three categories in order to increase the reflection on occupational health may be important, since all of them were expressed in life accounts, showing their permanence and relevance in the history of everybody and each one...
