Predators and tourism increase intolerance? Comment on A. Treves and J. Bruskotter Perspective in Ecology "Tolerance for predatory wildlife" (2 May, 344: 476)

Predators and Tourism Increase Intolerance? A. Treves and J. Bruskotter Perspective in Ecology "Tolerance for Predatory Wildlife" (2 May, 344: 476) suggest that intolerance for predators do not fit into the conventional view of perceived threats for livelihoods but instead by complex social factors. Although the above perspective focuses in jaguars, wolves, lions and bears, the same reasoning is perfectly applied to other economical contexts and different human-wildlife interactions. Nature tourism is a growing industry attracting a significant number of people to exotic places to see wildlife and, of course, many predators are on the main "menu". [...].

Routine screening of harmful microorganisms in beach sands: implications to public health

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes harmful to human health, often in concentrations greater than the beach water. Currently, there are no standards for monitoring, sampling, analyzing, or managing beach sand quality. In addition to indicator microbes, growing evidence has identified pathogenic bacteria, viruses, and fungi in a variety of beach sands worldwide. The public health threat associated with these populations through direct and indirect contact is unknown because so little research has been conducted relating to health outcomes associated with sand quality. In this manuscript, we present the consensus findings of a workshop of experts convened in Lisbon, Portugal to discuss the current state of knowledge on beach sand microbiological quality and to develop suggestions for standardizing the evaluation of sand at coastal beaches. The expert group at the "Microareias 2012" workshop recommends that 1) beach sand should be screened for a variety of pathogens harmful to human health, and sand monitoring should then be initiated alongside regular water monitoring; 2) sampling and analysis protocols should be standardized to allow proper comparisons among beach locations; and 3) further studies are needed to estimate human health risk with exposure to contaminated beach sand. Much of the manuscript is focused on research specific to Portugal, but similar results have been found elsewhere, and the findings have worldwide implications.

Integrated Management of Childhood Illness: efficiency of primary health in Northeast Brazil

OBJECTIVE: The Integrated Management of Childhood Illness is a strategy designed to address major causes of child mortality. The aim of this study was to assess the impact of the strategy on the quality of child health care provided at primary facilities. METHODS: Child health quality of care and costs were compared in four states in Northeastern Brazil, in 2001. There were studied 48 health facilities considered to have had stable strategy implementation at least two years before the start of study, with 48 matched comparison facilities in the same states. A single measure of correct management of sick children was used to assess care provided to all sick children. Costs included all resources at the national, state, local and facility levels associated with child health care. RESULTS: Facilities providing strategy-based care had significantly better management of sick children at no additional cost to municipalities relative to the comparison municipalities. At strategy facilities 72% of children were correctly managed compared with 56% in comparison facilities (p=0.001). The cost per child managed correctly was US$13.20 versus US$21.05 in the strategy and comparison municipalities, respectively, after standardization for population size. CONCLUSIONS: The strategy improves the efficiency of primary facilities in Northeastern Brazil. It leads to better health outcomes at no extra cost.

Knowledge, attitude and practice of mammography among women users of public health services

OBJECTIVE: To evaluate knowledge, attitude and practice related to mammography among women users of local health services, identifying barriers to its performance. METHODS: A total of 663 women were interviewed at 13 local health centers in a city of Southeastern Brazil, in 2001. Interviewees were randomly selected at each center and they were representative from different socioeconomic conditions. The number of interviewees at each center was proportional to monthly mean appointments. For data analysis, answers were described as knowledge, attitude, practice and their respective adequacies and then they were correlated with control variables through the chi-square test. RESULTS: Only 7.4% of the interviewees had adequate knowledge on mammography, while 97.1% of women had an adequate attitude. The same was seen for the practice of mammography that was adequate in 35.7% of the cases. The main barrier to mammography was lack of referral by physicians working at the health center (81.8%). There was an association between adequacy of attitude and five years or more of education and being married. There was also an association between adequacy of mammography practice and being employed and family income up to four minimum wages. CONCLUSIONS: Women users of local health services had no adequate knowledge and practice related to mammography despite having an adequate attitude about this exam.

Oral health, hygiene practices and oral cancer

OBJECTIVE: To assess the association between oral health and hygiene practices and oral cancer. METHODS: Hospital-based case-control study in the metropolitan area of São Paulo, southeastern Brazil, from 1998 to 2002. A total 309 patients with squamous cell carcinoma of the mouth and the pharynx and 468 controls matched by sex and age were included in the study. Cases were recruited in seven reference hospitals and controls were selected in five out of the seven participating hospitals. Detailed information on smoking, alcohol consumption, schooling, oral health status and hygiene practices were obtained through interviews. Odds ratios (OR) and 95% confidence intervals (95% CI), adjusted by sex, age, schooling, smoking, alcohol consumption as well as the variables oral health status and hygiene practices were estimated using unconditional logistic regression analyses. RESULTS: The use of complete dental prosthesis was not associated with oral cancer but regular gum bleeding showed a strong association (OR 3.1; 95% CI 1.2-7.9). Those who never attended a dental visit were more likely to have oral cancer (OR 2.5; 95% CI 1.3-4.8). Daily mouthwash use showed a stronger association to pharynx (OR 4.7; 95% CI 1.8-12.5) than mouth cancer (OR 3.2; 95% CI 1.6-6.3). CONCLUSIONS: Gum bleeding, no dental care, and daily mouthwash use were factors associated with oral cancer regardless of tobacco and alcohol consumption.

Comparing the content of instruments assessing environmental factors using the International Classification of Functioning, Disability and Health

Purpose: To describe and compare the content of instruments that assess environmental factors using the International Classification of Functioning, Disability and Health (ICF). Methods: A systematic search of PubMed, CINAHL and PEDro databases was conducted using a pre-determined search strategy. The identified instruments were screened independently by two investigators, and meaningful concepts were linked to the most precise ICF category according to published linking rules. Results: Six instruments were included, containing 526 meaningful concepts. Instruments had between 20% and 98% of items linked to categories in Chapter 1. The highest percentage of items from one instrument linked to categories in Chapters 2–5 varied between 9% and 50%. The presence or absence of environmental factors in a specific context is assessed in 3 instruments, while the other 3 assess the intensity of the impact of environmental factors. Discussion: Instruments differ in their content, type of assessment, and have several items linked to the same ICF category. Most instruments primarily assess products and technology (Chapter 1), highlighting the need to deepen the discussion on the theory that supports the measurement of environmental factors. This discussion should be thorough and lead to the development of methodologies and new tools that capture the underlying concepts of the ICF.

Consciencialização dos operadores turísticos para a consulta do viajante

Partindo de uma hipótese que se veio a demonstrar válida, de que os Operadores Turísticos em Portugal têm muito pouca informação sobre a consulta do viajante e o seu papel em responsabilidade na promoção da saúde dos seus clientes, apresenta-se neste trabalho não só uma análise da situação anteriormente referida como uma estratégia de comunicação visando consciencializar os Operadores Turísticos para a necessidade de fomentarem a adesão dos seus clientes à consulta do viajante. Dois temas emergem como centrais, nomeadamente a questão do turismo na nossa contemporaneidade e a saúde dos que viajem essencialmente para fora da Europa em turismo. Transversal a todo o trabalho encontra-se a noção de comunicação e saúde, especialmente na sua vertente de comunicação para a saúde. Defende-se que a comunicação para a saúde pode ser pensada como um fator competitivo para os Operadores Turísticos e apresenta-se uma estratégia de comunicação subordinada ao título: “Projeto de Consciencialização dos Operadores para a Consulta do Viajante”. Na primeira parte apresenta-se uma revisão da literatura e de outras fontes sobre os temas: Turismo, Consulta do Viajante e Comunicação para a Saúde, e na segunda parte o projeto que já referi. Partindo da hipótese inicialmente formulada, para uma análise completa da situação utilizaram-se metodologias de análise qualitativa e quantitativa junto dos principais públicos envolvidos a saber os Operadores Turísticos.

Comunicação na saúde: a consulta do viajante no IHMT

O presente trabalho, é um Relatório de Estágio onde se descrevem as actividades desenvolvidas ao longo do Estágio Curricular realizado no Instituto de Higiene e Medicina Tropical (IHMT) no período de 5 de Novembro de 2012 a 8 de Março de 2013. Pretendeu-se aliar o estudo da teoria ao desenvolvimento de algumas acções de comunicação que colmatassem falhas detectadas durante a auditoria à comunicação. O Relatório de Estágio, aqui apresentado, divide-se em duas secções: a investigação e o desenvolvimento dos instrumentos de comunicação. Estas duas secções encontram-se intimamente ligadas pois, a investigação efectuada teve como principal objectivo a obtenção de dados que permitissem caracterizar o público da Consulta do Viajante do IHMT de modo a que fosse possível a alteração e/ou criação de suportes de comunicação adaptados às características – escolares, sociais, demográficas, profissionais, etc. – desse público. Desta forma, e após pesquisa bibliográfica sobre temas pertinentes para o trabalho como Medicina do Viajante, Comunicação em e para a Saúde, Metodologias de Investigação, entre outras tidas como necessárias, foi realizada uma investigação por questionário aos utentes do IHMT que permitiu o desenvolvimento do trabalho final de estágio. A investigação e consequente desenvolvimento dos suportes de comunicação são apresentados neste relatório que se pretende reflexivo sobre as práticas desenvolvidas.
