Abstract: objective: to understand the meanings attributed to self-assessment of health by the elderly. methods: qualitative study performed with 17 elderly individuals (> 70 years of age) of both sexes, living in the city of bambuí, southeastern brazil, in 2008. an anthropological approach based on the model of signs, meanings and actions, which associates individual actions, cultural codes and the macro-social context, was used. semi-structured interviews were conducted, focusing on self-assessment of health, description of health as "good" and "poor" and the criteria used by the elderly to rate their own health. analysis of results: the idea organizing reports associates self-assessment of health by the elderly with the "participating in life" and "being anchored in life" logics. the first logic has autonomy as its basic line of thinking, including the following categories: remaining active within advanced instrumental and functional abilities, being in charge of one's life (as opposed to being dependent on others), being able to solve problems and acting at will. the second logic unites the following categories: being able to interact, being engaged in meaningful relationships and being able to rely on family members, friends and neighbors. conclusions: health is understood by the elderly as having autonomy in the exercise of functional abilities required by society, such as the ability to meet family obligations and the ability to perform social roles. by defining their health as good or fair, the elderly individual is not characterized as someone free from diseases, but rather able to act over the environment.

Abstract: the object of this study was to identify context elements that have an influence on pesticide use, related perceptions, and actions in flower production. the study was carried out in barbacena, minas gerais state. the method used was based on an anthropological fast diagnosis approach inspired on the signs, meanings and actions model and on the analysis of semi-structured interviews with 20 workers from four different flower-growing fields. the field data analysis indicates that these workers face two realities: the need for pesticides and suffering generated by pesticide management. furthermore, there is clearly no direct relation between risk awareness and the effective hazards associated with pesticides. this gap is filled by beliefs which are at the basis of their actions. these beliefs reinterpret information and risk, influence behavior, and make it possible for these workers to move between these two paradoxical realities and pesticide. attributing new meanings to pesticide management risks, however, may imply in positively valuing potentially harmful behaviors.
γδ T Lymphocytes Coordinate Eosinophil Influx during Allergic Responses
Maria Das Gra?as Muller de Oliveira Henriques,Carmen Penido
Frontiers in Pharmacology , 2012, DOI: 10.3389/fphar.2012.00200
Abstract: Tissue eosinophil infiltration, which is a hallmark of allergic and helminthic diseases, is mainly coordinated by T lymphocytes, via the production of eosinophilotactic chemokines. Among T lymphocyte subsets, lymphocytes expressing γδ T cell receptor have been determined as a key factor for eosinophil accumulation via direct and indirect mechanisms. This knowledge is strongly supported by the fact that, in different experimental models of eosinophilic airway inflammation and helminth-induced Th2 lung inflammation, an evident tissue accumulation of γδ T lymphocytes is observed. In addition, the depletion of γδ T lymphocytes is correlated with the impairment of eosinophil accumulation in inflamed tissue. γδ T lymphocytes are non-conventional T lymphocytes, which comprise a minor T lymphocyte subset, mainly distributed in the tissue, and present crucial roles in innate and acquired immune responses. γδ T lymphocytes recognize several danger- and pathogen-associated molecular pattern molecules and stress antigens in a MHC-independent fashion and can provide rapid tissue-specific responses, via the production of a wide range of chemical mediators capable to modulate other cell populations. These mediators include chemoattractant cytokines and chemokines that attract eosinophils into the tissue by either direct recognition (such as IL-5, CCL11/eotaxin), or indirect mechanisms via the modulation of αβ T lymphocytes and macrophages (through the production of interferon-γ, IL-4, and CCL2/Monocyte chemoattractant protein-1, MCP-1, for example). The present review presents an overview of how γδ T lymphocytes coordinate eosinophil accumulation in allergy, by focusing on their role in airway inflammation and by discussing the involvement of cytokines and chemokines in this phenomenon.

Cadernos de Saúde Pública , 2011, DOI: 10.1590/S0102-311X2011001500007
Abstract: this paper explores the contribution of anthropological perspectives for clarifying the mechanisms through which socioeconomic circumstances influence the strategies developed by elderly for addressing their health problems in a small brazilian city. interviews with 20 key-informants explored the community's broad perception of the health situation of the elderly. life histories collected from 30 elderly women examined their own perception of their health status and their health strategies. narratives converge in emphasising the important role played by financial factors in accessing health services and medication. life histories also describe some damaging strategies resorted to by the elderly to deal with their lack of resources. elderly women emphasize the crucial support they receive from their family and/or neighbours to overcome health problems. thus, the issue of poverty is not only a matter of socioeconomic circumstances, but also the poverty of broader social networks.

Abstract: this ethno-epidemiological inquiry aims to comprehend hypertension-related experiences in the elderly population of bambuí, in the state of minas gerais, brazil. it combines ethnographic descriptions with statistical data. the subjective significance of factors associated with adequate arterial pressure control is explored. a baseline cohort of 26 people with hypertension, randomly selected from a total number of 1,494 residents over the age of 60, was interviewed utilizing signs, meanings and actions methodology. multivariate analysis shows an association (p < 0.001) between female gender and monthly household income and treatment of hypertension and adequate blood pressure control. the number of doctor visits is associated with treatment but not with adequate blood pressure control. conflicting cultural construction of "blood pressure problems" contributes to "non-adherence" to treatment. there is a fine line between blood pressure "control" and what is perceived as health professionals "controlling" patients' lives. doctor-prescribed regimes are perceived as "prohibiting life's pleasures" and "controlling" personal liberty and free choice. giving elderly people a voice regarding their social context can promote autonomy, well-being and happiness in later life.

Abstract: the objective of this study was to determine the prevalence and factors associated with the needs of caregivers for older adults living in the community. all residents (n = 1,742) of bambuí, minas gerais state, brazil (15,000 inhabitants) aged > 60 years were selected. of these, 92% were interviewed and 86% were examined. the dependent variable "need for a caregiver" was defined as the inability to perform at least one of the basic activities of daily living and/or a mini mental score under 13. some 23% of the elderly required caregivers. after adjustment for confounding, independent and positive associations with the need for a caregiver were found for: age, single marital status, history of alcohol abuse, hypertension, obesity, and use of > 2 prescription drugs. independent and negative associations were found for: level of schooling, familiar income, living alone, total cholesterol > 240mmhg, and having a private health plan. those requiring caregivers presented evidence of worse socioeconomic and health status. the study provides evidence that care of the dependent elderly is a public health problem.

Abstract: objective: to determine factors associated with self-rated health among older adults, considering five dimensions: sociodemographic variables, social support, lifestyle risk factors, health status, and access to/use of healthcare services. methods: of the 1,742 older adults (>60 years) living in the town of bambuí (southeastern brazil), 1,516 (87.0%) participated in the study. information was obtained by means of standardized interviews and physical and laboratory exams. results: self-rated health as good/very good, reasonable, and poor/very poor was reported by 24.7%, 49.2%, and 26.1% of subjects, respectively. the following characteristics showed independent positive associations with worse self-rated health: social ties (dissatisfaction with social network, attendance to clubs and associations), health status (symptoms of depression/anxiety in the last two weeks, sleeplessness in the last 30 days, greater number of prescribed medications used in the last 30 days), and access to/use of healthcare services (complaints when seeking medical care, greater number of medical appointments in the last 12 months, greater number of hospital admissions in the last 12 months). an independent negative association was found with monthly family income (<2.0 vs. >4 minimum wages). conclusions: our results show that self-rated health among older adults is multidimensional in structure, being influenced by socioeconomic conditions, social support, health status (with emphasis on mental health), and access to/use of healthcare services. this structure resembles the definition of health adopted by the world health organization (an individual's "physical, mental and social well-being").

Abstract: Objective. To describe, for the first time in Brazil, the prevalence of risk factors and the use of preventive health care services among adults 60 years and older. Methods. This population-based study was conducted during 1996-1997 in the state of Minas Gerais, in the town of Bambuí, which is located in the municipality of the same name. In 1996 the town had 14 950 inhabitants. For the study, all the town's residents aged > or = 60 years were selected, along with a comparison sample of persons aged 18-59 years. Data were gathered using interviews and physical examinations. Results. Of the 1 742 inhabitants of the town of Bambuí aged > or = 60 years, 1 606 (92.2%) participated in the interview and 1 495 (85.8%) were examined (blood pressure, anthropometric measurements, and blood tests). Among the 1 020 younger adults selected for the survey, 909 of them (89.1%) participated in the interview, and 820 of them (80.4%) underwent the physical examination. The prevalence of the following risk factors was higher among older adults than among younger adults: physical inactivity (47.7% vs. 28.0%); blood pressure 140-159 mmHg (systolic) or 90-99 mmHg (diastolic) (25.8% vs. 8.7%); blood pressure > or = 160 mmHg (systolic) or > or = 100 mmHg (diastolic) (19.1% vs. 4.1%); total cholesterol > or = 240 mg/dL (40.6% vs. 9.8%); and blood glucose > or = 126 mg/dL (12.4% vs. 2.2%). The daily consumption of fruits and vegetables was similar among the older adults and the younger ones (51.9% and 51.7%), as was also body mass index > or = 25 kg/m2 (51.6% and 56.2%). Smoking was lower among the older adults (18.7%) than among the younger ones (31.1%). The proportion of participants whose blood pressure had been checked in the preceding year was high (86.8% among the older adults and 61.2% among the younger ones), suggesting that the high prevalence of uncontrolled hypertension was not due to limited access to health care. Conclusions. For a long time it was believed that the kinds of risk factors that we found in the urban section of the municipality of Bambuí were public health problems only in large Brazilian cities. Around 72% of the municipalities in Brazil have<= 20 000 inhabitants, and these smaller municipalities contain some 19% of the country's entire population. The high prevalence of various risk factors among the older and younger adults in Bambuí indicates a great need for health promotion and disease prevention actions. More research is needed to find out whether our results in Bambuí reflect the reality of other small towns in Brazil.

Abstract: A abordagem antropológica foi empregada para investigar o universo de representa es (maneiras de pensar) e comportamentos (maneiras de agir) associados à doen a de Chagas, por um grupo de trabalhadores de um servi o público de Belo Horizonte (infectados/n o infectados). Procurou-se também avaliar as repercuss es deste universo de representa es e comportamentos sobre a vida dos indivíduos infectados. A coleta e a análise dos dados, inspirou-se no modelo dos "sistemas de signos, significados e a es", elaborado por Corin et al. (1989, 1992). Foram entrevistados 16 informantes chave, selecionados entre os trabalhadores soro-positivos e 12 entre os trabalhadores soro-negativos, com o objetivo de comparar as maneiras de pensar e agir, predominantes nesses dois grupos. A análise dos dados, permitiu identificar diversos elementos do contexto que vêm maximizar as limita es impostas pela doen a de Chagas, e que devem ser levados em conta no planejamento de campanhas educativas e na elabora o de modelos de aten o ao paciente chagásico.
