Restaurant Health and Hygiene: A Model Program with Theory-Based Guidelines for Implementation

Poor hygienic practices and illness of restaurant employees are major contributors to the contamination of food and the occurrence of food-borne illness in the United States, costing the food industry and society billions of dollars each year. Risk factors associated with this problem include lack of proper handwashing; food handlers reporting to work sick; poor personal hygiene; and bare hand contact with ready-to-eat foods. However, traditional efforts to control these causes of food-borne illness by public health authorities have had limited impact, and have revealed the need for comprehensive and innovative programs that provide active managerial control over employee health and hygiene in restaurant establishments. Further, the introduction and eventual adoption by the food industry of such programs can be facilitated through the use of behavior-change theory. This Capstone Project develops a model program to assist restaurant owners and operators in exerting active control over health and hygiene in their establishments and provides theory-based recommendations for the introduction of the program to the food industry.

Prerequisite Programs at Schools: Diagnosis and Economic Evaluation

In this study, 20 Brazilian public schools have been assessed regarding good manufacturing practices and standard sanitation operating procedures implementation. We used a checklist comprised of 10 parts ( facilities and installations, water supply, equipments and tools, pest control, waste management, personal hygiene, sanitation, storage, documentation, and training), making a total of 69 questions. The implementing modification cost to the found nonconformities was also determined so that it could work with technical data as a based decision-making prioritization. The average nonconformity percentage at schools concerning to prerequisite program was 36%, from which 66% of them own inadequate installations, 65% waste management, 44% regarding documentation, and 35% water supply and sanitation. The initial estimated cost for changing has been U.S.$24,438 and monthly investments of 1.55% on the currently needed invested values. This would result in U.S.$0.015 increase on each served meal cost over the investment replacement within a year. Thus, we have concluded that such modifications are economically feasible and will be considered on technical requirements when prerequisite program implementation priorities are established.

An e-marketplace of healthcare and social care services: the perceived interest

Purpose – The health and social care sector is receiving growing attention due to the increased life expectancy and to the public demand for a better quality of life and better health services. New cost-efficient approaches are required, and the paper aims to present and discuss the main results of a study undertaken in a Portuguese municipality on the perceived relevance of an e-marketplace of social and healthcare services for the inhabitants in general, and for people with special needs in particular, and the identification of the most relevant services to be offered through this platform. Design/methodology/approach – A wide survey was undertaken to identify the needs of potential users and their expectancies with relation to the proposed platform. The results of the study are a support for the project promoters to understand the viability of the solution and the requirements to the deployment of the pilot experiment, as well as to drive the selection of domains of activities/classes of services to be offered by the platform. Findings – Services such as information about healthcare services, home monitoring/accompanying services 24 hours per day, and personal hygiene services provided at home are the ones recognized by the inquired citizens as the most important, which indicates that the potential users will be mostly people with special needs or their family or caregivers. Originality/value – While still at a preliminary development phase, the project represents a good opportunity to develop a totally innovative service with high potential impact for the senior population and for individuals with special needs.

Caracterização dos estilos de vida dos sem-abrigo da cidade do Porto

O fenómeno dos sem-abrigo está em constante crescimento nos centros urbanos, na cidade no Porto o mesmo acontece, sendo esta uma realidade ainda pouco conhecida. Têm sido realizados alguns estudos sobre esta problemática, no entanto poucos incidem sobre a população portuguesa, pouco se sabe sobre como vivem estes indivíduos e sobre o que define o seu estilo de vida. Os estilos de vida têm vindo a ser uma área de crescente interesse para estudo, visto que afecta a nossa saúde e a longo prazo tem influência nos padrões de morbilidade e mortalidade. Com este estudo procurou-se caracterizar os sem-abrigo da cidade do Porto e os comportamentos que tipificam o seu estilo de vida, bem como verificar se existem variáveis dos estilos de vida que se encontram correlacionadas com a presença de sintomatologia psicopatológica. Para este efeito, foi realizado um inquérito por questionário a 30 pessoas que vivem na condição de sem-abrigo na cidade do Porto, através da administração de um questionário de estilos de vida e da Brief Psychiatric Rating Scale (BPRS). Concluímos que os sem-abrigo se caracterizam por ser do sexo masculino, solteiros de nacionalidade portuguesa e baixa escolaridade. Constatamos que a maioria apresenta comportamentos pouco saudáveis como fumar e não praticar exercício físico, contudo têm cuidado com a higiene pessoal, apresentam uma boa higiene do sono e manifestam poucos comportamentos sexuais de risco. Verificamos que a ansiedade se encontra correlacionada negativamente com o stress, higiene do sono, insight e alimentação. As perturbações somáticas mostraram uma correlação com a higiene do sono, o humor depressivo com a higiene do sono e insight, o retraimento emocional com a socialização e falta de cooperação com a socialização, sendo todas estas correlações negativas. Encontramos ainda uma correlação positiva entre a lentificação e o consumo de substâncias e uma correlação negativa entre a lentificação e higiene do sono. Considerando os resultados obtidos pensamos ser fundamental prosseguir com estudos de investigação nesta área, para que de futuro as intervenções junto desta população consigam dar uma melhor resposta ao seu estado de saúde.

Exposição a fungos dos trabalhadores dos ginásios com piscina

RESUMO - Os trabalhadores dos ginásios com piscinas apresentam maior prevalência de lesões fúngicas, como a Tinea pedis e a onicomicose, devido às características intrínsecas da sua actividade profissional, pois apresentam mais horas por dia de exposição à contaminação fúngica das superfícies. Esta situação verifica-se não só por serem os que mais frequentam os locais possíveis de estarem contaminados, como é o caso de balneários, vestiários e zona envolvente às piscinas, mas também porque algumas das actividades desenvolvidas são realizadas com os pés descalços. Além disso, a utilização de roupa sintética e de calçado ocluso, que retêm a sudação excessiva, favorece o desenvolvimento fúngico. Constituiu objectivo deste trabalho conhecer o risco de infecção e/ou lesão (Tinea pedis e onicomicose) nos trabalhadores dos ginásios com piscina e a sua eventual relação com a exposição à contaminação fúngica (ar e superfícies) dos locais de trabalho. Foram descritas as variáveis ambientais e biológicas que influenciam a infecção e/ou lesão fúngica em ambiente profissional e exploradas eventuais associações entre essas mesmas variáveis. Foram também conhecidas as diferenças da contaminação fúngica das superfícies entre as duas principais estações do ano (Verão e Inverno) e entre antes e depois da lavagem e desinfecção. O estudo realizado possui uma componente transversal, em que se pretendeu descrever os fenómenos ambientais e biológicos da contaminação fúngica em ambiente profissional e explorar eventuais associações entre variáveis; uma componente longitudinal, em que foram conhecidas as diferenças sazonais da contaminação fúngica das superfícies; e, ainda, uma componente quase experimental, em que foi analisada a distribuição fúngica nas superfícies antes e depois da lavagem e desinfecção. Na vertente transversal foi considerada uma amostra de 10 ginásios com piscina e outra amostra de, pelo menos, 10 profissionais de cada estabelecimento, perfazendo um total de 124 trabalhadores (75 Homens - 60,48% e 49 Mulheres - 39,52%). Foram realizadas 258 colheitas biológicas aos pés dos trabalhadores, efectuada a avaliação ambiental da contaminação fúngica dos estabelecimentos através de 50 colheitas de amostras de ar e 120 colheitas de amostras de superfícies (60 antes e 60 depois da lavagem e desinfecção) e efectuados os respectivos processamento laboratorial e identificação fúngica. Foram também avaliadas as variáveis ambientais temperatura, humidade relativa e velocidade do ar, preenchidas 10 grelhas de observação, com o objectivo de efectuar o registo de informação sobre as variáveis que xx influenciam a exposição ocupacional às espécies fúngicas e, ainda, completadas 124 grelhas de observação inerentes à colheita de material biológico, de modo a realizar o registo dos profissionais com lesão e outras informações pertinentes para a análise laboratorial. Todos os 124 trabalhadores responderam a um questionário, em simultâneo à realização das colheitas biológicas, de modo a conhecer algumas das variáveis individuais e profissionais com pertinência para o presente estudo. Num dos estabelecimentos, foram também estudadas as diferenças da contaminação fúngica das superfícies entre antes e depois da lavagem e desinfecção e, ainda, entre as duas estações do ano (Verão e Inverno). Nesse estabelecimento, foram realizadas 36 colheitas de superfícies antes e 36 colheitas depois da lavagem e desinfecção, em 6 dias diferentes da semana, durante 6 semanas sequenciais em cada estação do ano, completando um total de 72 colheitas de superfícies. Foi ainda criado e aplicado um método para estabelecer um padrão de exposição profissional a fungos nas superfícies, de modo a permitir definir níveis semi-quantitativos de estimação do risco de infecção fúngica dos trabalhadores dos ginásios com piscinas. Para o critério da Gravidade, considerou-se que a gravidade da contaminação e, consequentemente, da possível lesão, está intimamente relacionada com a espécie fúngica envolvida. Foram calculadas as médias da contaminação fúngica por cada estabelecimento antes da lavagem e desinfecção, de modo a estabelecer os níveis de Frequência e, em relação à Exposição, foram estabelecidos intervalos para agrupar as horas semanais de trabalho. Dos 124 trabalhadores que participaram no estudo, 58 (46,8%) possuíam lesões visíveis. Nesses 58, as Leveduras foram as mais isoladas (41,4%), seguidas dos Dermatófitos (24,1%) e de Fungos Filamentosos Não Dermatófitos (6,9%). Candida parapsilosis e Rhodotorula sp. foram as Leveduras mais frequentemente isoladas (20,2%); no caso dos Dermatófitos, Trichophyton rubrum foi a espécie mais frequente (55,5%) e, relativamente aos Fungos Filamentosos Não Dermatófitos, Penicillium sp. foi o mais isolado (15,6%), seguido do género Fusarium (12,5%). No que concerne à contaminação fúngica das superfícies, 37 fungos filamentosos foram isolados. Fusarium foi o género mais frequente, antes e depois da lavagem e desinfecção (19,1% - 17,2%). Em relação aos fungos leveduriformes, 12 leveduras diferentes foram identificadas, tendo sido os géneros Cryptococcus (40,6%) e Candida (49,3%) os mais frequentes antes e depois da lavagem e desinfecção, respectivamente. Em relação à contaminação fúngica do ar, foram identificados 25 fungos filamentosos diferentes, em que os 3 géneros mais frequentemente isolados foram Cladosporium (36,6%), Penicillium (19,0%) e Aspergillus (10,2%). Relativamente às leveduras, foi identificado o género xxi Rhodotorula (87,5%) e as espécies Trichosporon mucoides e Cryptococcus unigutulattus (12,5%). Verificou-se associação, ao nível de significância de 5%, entre lesão visível e horas semanais e entre lesão visível e tempo de profissão, comprovando a influência da duração da exposição ao factor de risco (contaminação fúngica do ambiente profissional), para a presença de lesão visível nos trabalhadores expostos (Tinea pedis e onicomicose), ficando demonstrada a relação entre a exposição ao factor de risco em estudo – exposição profissional a fungos – com os efeitos para a saúde. As variáveis ambientais avaliadas (temperatura, humidade relativa e velocidade do ar) não influenciaram a contaminação fúngica do ar e das superfícies, não tendo sido evidenciada nenhuma relação estatisticamente significativa (p>0,05). Contudo, verificou-se influência do número de ocupantes que frequentaram cada um dos estabelecimentos nas médias das unidades formadoras de colónias por metro quadrado nas superfícies antes da lavagem e desinfecção. Não se verificou correlação entre os resultados quantitativos da contaminação fúngica do ar e a das superfícies dos 10 estabelecimentos monitorizados. No entanto, verificaram-se diferenças significativas, ao nível de significância de 10%, entre a contaminação fúngica das superfícies e a contaminação fúngica do ar (p<0,1), tendo-se constatado que apesar de 50% dos valores mais baixos terem sido superiores na contaminação fúngica do ar, a contaminação fúngica das superfícies apresentou-se com maior variabilidade quantitativa. Em relação às diferenças significativas na contaminação fúngica das superfícies nos 10 estabelecimentos entre antes e depois da lavagem e desinfecção, apenas se verificou redução significativa (p<0,05) da contaminação fúngica depois da lavagem e desinfecção nos balneários e vestiários masculinos em relação aos fungos leveduriformes. No estabelecimento seleccionado, verificou-se que a relação entre a contaminação fúngica e a temperatura e humidade relativa não foi significativa (p>0,05) em ambas as estações do ano e também não se constatou influência dos ocupantes nos valores médios das unidades formadoras de colónias por metro quadrado das superfícies antes da lavagem e desinfecção em ambas as estações de ano. Em quase todas as situações em que se verificaram diferenças significativas entre as duas estações do ano, verificou-se um aumento das unidades formadoras de colónias por metro quadrado no Inverno, com excepção do total das unidades formadoras de colónias por metro quadrado antes da lavagem e desinfecção nos balneários e vestiários masculinos em que se verificou aumento no Verão. Constatou-se também que apenas ocorreu redução da xxii contaminação fúngica depois da lavagem e desinfecção nas escadas de acesso no Inverno e nos balneários e vestiários masculinos no Verão. Com a aplicação do método para estabelecer um padrão de exposição profissional a fungos nas superfícies obteve-se, nos 10 estabelecimentos, com Nível de Risco Mínimo 65 locais (54,2%), com Nível de Risco Médio 23 locais (19,2%) e com Nível de Risco Elevado 32 locais (26,6%). Próximo do jacuzzi e junto ao tanque foram os locais com mais classificações de Nível de Risco Elevado. No estabelecimento seleccionado verificou-se que, no Verão, depois da lavagem e desinfecção, ocorreu um maior número de locais classificados no Nível de Risco Elevado e, no Inverno, constatou-se a situação inversa, tendo sido observado maior número de locais com Nível de Risco Elevado antes da lavagem e desinfecção. Junto ao tanque e nas escadas de acesso à zona envolvente ao jacuzzi e tanque foram os locais com mais classificações de Nível de Risco Elevado, no Verão e no Inverno. Foram isolados nas superfícies fungos comuns aos isolados nos trabalhadores. Antes da lavagem e desinfecção, 30,3% dos fungos foram isolados nas superfícies e nos trabalhadores e depois desses procedimentos 45,5% dos fungos foram também isolados comummente. As Leveduras foram as mais isoladas comummente e as que se verificaram mais frequentes antes e depois da lavagem e desinfecção da superfícies e, também, nos resultados das colheitas biológicas realizadas aos trabalhadores, foram o género Rhodotorula e a espécie Candida parapsilosis, permitindo confirmar que a infecção fúngica dos trabalhadores está relacionada com a contaminação fúngica das superfícies. Concluiu-se que é necessária a intervenção em Saúde Ocupacional no âmbito da vigilância ambiental e da vigilância da saúde, com o intuito de diminuir a prevalência das infecções fúngicas. Para a prossecução desse objectivo, sugere-se a implementação de medidas preventivas, nomeadamente: o controlo da contaminação fúngica das superfícies mediante procedimentos de lavagem e desinfecção eficazes, de modo a minimizar a contaminação fúngica das superfícies; a identificação precoce da infecção através da realização de colheitas biológicas periódicas aos trabalhadores, inseridas num protocolo de vigilância da saúde; e, ainda, a sensibilização para a aplicação de medidas de higiene pessoal e o tratamento das patologias. A aplicação do método criado para estabelecer um padrão de exposição profissional a fungos nas superfícies servirá não só para a estimação do risco de infecção fúngica dos trabalhadores de ginásios com piscinas, mas também para facilitar o estabelecimento de valores fúngicos de referência, a implementação de medidas correctivas adequadas e imediatas e, ainda, a prevenção de infecções fúngicas, não só nos ginásios com piscina, mas também noutros contextos profissionais. ------------ SUMMARY - Gyms with swimming pools workers have higher prevalence of fungal injuries, such as Tinea pedis and onychomycosis. This is due to their work intrinsic characteristics, since they have more hours per day of exposure to surfaces fungal contamination. This occurs not only because they attend sites most likely to be contaminated, such as showers, changing rooms and pool surrounding area, but also because some of the activities are done barefoot. Furthermore, synthetic clothing and occluded footwear use, which retain the excessive sweating, promotes fungal development. The aim of this study was to know gymnasiums with swimming pool workers infection and/or injury (Tinea pedis and onychomycosis) risk, and its possible relationship with exposure to workplace fungal contamination (air and surfaces). This study describes environmental and biological variables that influence infection and/or fungal injury in a professional setting and explored possible associations between these variables. Differences in surfaces fungal contamination between the two main seasons (summer and winter), as well between before and after cleaning and disinfection were known. It was developed a study with an cross-sectional perspective, that aimed to describe the biological and environmental phenomena of fungal contamination in a professional environment and explore possible associations between variables; an longitudinal perspective in which were known surfaces fungal contamination seasonal differences; and also with an almost experimental perspective that analyzed surfaces fungal distribution before and after cleaning and disinfection. The cross-sectional perspective comprised 10 gyms with swimming pool sample, and another sample of, at least, 10 professionals in each establishment totalling 124 workers (75 men – 60,48%, and 49 women – 39,52%). Were performed 258 biological samples at workers feet, environmental fungal contamination evaluation from the establishments through 50 air samples and 120 surfaces samples (60 before and 60 after cleaning and disinfection) and conducted their laboratory processing and fungal identification. Were also evaluated environmental variables, such as temperature, relative humidity and air velocity completed 10 observation grids, in order to obtain data about variables that affect occupational exposure to fungal species, and also completed 124 observation grids inherent to biological material collection, in order to know the professionals with injury and other relevant information for laboratory analysis. All 124 workers answered to a questionnaire at the same time that occur biological samples collection, in order to xxv obtain information about some of the individual and professional variables with relevance to this study. In one of the establishments were also studied differences concerning surfaces fungal contamination between before and after cleaning and disinfection, and also between two main seasons (summer and winter). In this setting, there were performed 36 surfaces samples before and 36 surfaces samples after cleaning and disinfection on 6 different week days for 6 sequential weeks in each season, totalling 72 surfaces samples. It was also created and implemented a method to establish a pattern for surfaces fungal occupational exposure, in order to help define semi-quantitative levels estimation to fungal infection risk in gyms with swimming pools workers. For Gravity criterion it was considered that contamination severity and, thus, the possible injury are closely related to implicate fungal species. Was calculated fungal contamination average by each establishment prior cleaning and disinfection, in order to establish Frequency levels. Regarding Exposure, were established weekly hours group intervals spent in professional activity. From the 124 professionals tested, 58 (46,8%) had visible injuries. In the 58 workers, Yeasts were the most isolated (41,4%), followed by Dermatophytes (24,1%) and Other Filamentous Fungi Besides Dermatophytes (6,9%). Candida parapsilosis and Rhodotorula sp. were the most frequently isolated Yeasts (20,2% for each), from Dermatophytes, Trichophyton rubrum was the most frequently isolated species (55,5%) and from Other Filamentous Fungi Besides Dermatophytes, Penicillium sp. was the most frequent (15,6%), followed by Fusarium genera (12,5%). Regarding surfaces fungal contamination, 37 filamentous fungi were isolated. Fusarium genera was the most frequent, before and after cleaning and disinfection (19,1% - 17,2%). Considering yeasts, 12 different yeasts were identified, being Cryptococcus (40,6%) and Candida (49,3%) genera the more frequent before and after cleaning and disinfection, respectively. In relation to air fungal contamination, 25 different filamentous fungi were identified and the 3 most frequently isolated genera were Cladosporium (36,6%), Penicillium (19,0%) and Aspergillus (10,2%). For yeasts, were identified Rhodotorula genera (87,5%), and also the species Trichosporon mucoides and Cryptococcus unigutulattus (12,5%). Was found association with 5% significance level, between visible injury and weekly hours and between visible injury and occupation time, confirming exposure duration influence to risk factor (work environment fungal contamination) for the visible injury presence in exposed workers (Tinea pedis and onychomycosis), being confirmed the relation between the study exposure risk - occupational exposure to fungi - with health effects. xxvi Environmental variables evaluated (temperature, relative humidity and air velocity) did not affect air and surfaces fungal contamination and wasn’t found no statistically significant relation (p>0,05). However, there was evidence that occupant’s number influence surfaces colony forming units mean per square meter before cleaning and disinfection. There was no correlation between quantitative data from air fungal contamination and surfaces fungal contamination from the 10 establishments monitored. However, there were significant differences with 10% significance level, between surfaces and air fungal contamination (p<0,1), and despite 50% of the lowest rates were higher in air fungal contamination, it was found that surfaces fungal contamination had more quantitative variability. Regarding differences from the 10 establishments surfaces fungal contamination, between before and after cleaning and disinfection, there was only a significant reduction (p<0,05) in fungal contamination after cleaning and disinfection in male changing rooms for yeasts. In the selected establishment, it was found that relation between fungal contamination and temperature and relative humidity was not significant (p>0,05) in both seasons, and also there wasn’t no influence observed from occupants in surfaces colony forming units mean per square meters before cleaning and disinfection in both seasons. In almost all situations where significant differences between the two seasons were shown, there was a colony-forming units per square meter increase in winter. There was an exception in total colony forming units per square meter before cleaning and disinfection in male changing room’s exception, where there was an increase in summer. Furthermore, was found that only occur a reduction in fungal contamination after cleaning and disinfection, on access stairs in winter, as well as in male changing rooms in summer. With application from the method to establish pattern for surfaces fungal occupational exposure, it was obtained, in the 10 establishments, 65 sites with Low Risk Level (54,2%), 23 sites with Average Risk Level (19,2%) and 32 sites with High Risk Level (26,6%). Near swimming pool and jacuzzi were the places with more High Risk Level classifications. In the selected establishment, was found that in the summer, after cleaning and disinfection, there were a greater number of sites classified as High Risk Level, and in winter it was found the opposite situation, being noted more places with High Risk Level before cleaning and disinfection. Next to swimming pool and access stairs to swimming pool and jacuzzi were the places with more High Risk Level classifications in Summer and Winter. Were isolated common fungi in surfaces and in workers. Prior to cleaning and disinfection 30,3% of fungi were isolated on surfaces and workers, and after 45,5% of fungi were also xxvii commonly isolated. The Yeasts were the most commonly isolated and the most frequent before and after surfaces cleaning and disinfection, and also in workers biological samples, were Rhodotorula genera and Candida parapsilosis, allowing confirming that workers fungal infection is related with surfaces fungal contamination. It was concluded that Occupational Health intervention it is necessary, in environmental monitoring and health surveillance perspective, in order to reduce fungal infections prevalence. To achieve this objective, preventive measures implementation it’s recommended, including: surfaces fungal contamination control, through effective cleaning and disinfecting in order to minimize surfaces fungal contamination; early infection identification by performing periodic biological sampling from workers, included in a health surveillance protocol; and also personal hygiene and diseases treatment awareness. Application of the created method to establish pattern for surfaces fungal occupational exposure, will be useful not only for estimating workers from gymnasiums with swimming pools fungal infection risk, but also to facilitate fungal reference values stipulation, effective and corrective measures implementation, and also, fungal infections prevention, not only in gymnasiums with swimming pool, but also in other professional settings.----------------- RÉSUMÉ - Les travailleurs des gymnases avec des piscines présentent souvent des infections fongiques, telles que Tinea pedis et aussi des onychomycoses, dues à leur activité professionnel, parce qu’ils restent plus longtemps tout prés des surfaces avec une certaine contamination fongique. Toute cette situation est due non seulement parce qu’ils sont ceux qui fréquentent plus souvent les places plus contaminées: des balnéaires, des vestiaires et des zones autour des piscines, mais aussi ils réalisent des activités aux pieds nus ou avec des chaussures très fermés et encore quelques fois avec des vêtements synthétiques. Tout cela emmène à une grande sudation ce qui aidera au développement fongique. Un objective de ce travaille a été connaître le risque d’infection et/ou présence de lésion (Tinea pedis et des onychomycoses) dans les travailleurs des gymnases avec des piscines et leur éventuel rapport avec l’exposition à la contamination fongique (de l’air et des surfaces) dans leurs locaux de travaille. On a décrit aussi des variables d’environnement et biologiques qui ont une certaine influence dans les infections fongiques dans tout l’environnement professionnel et aussi approfondir des éventuels associations entre ces même variables. On a encore reconnu des différences de la contamination fongique avant et après des lavages et désinfection de ces surfaces. Aussi on a trouvé des différences de contamination en Été et en Hiver. Cet étude a un composante transversale, en visant la description des phénomènes de contamination fongique biologique et de l'environnement dans un environnement professionnel et l’étude des associations possibles entre les variables; une composante longitudinale dans laquelle ils étaient connus comme des variations saisonnières de la contamination fongique des surfaces, et même; un quasi-composante expérimentale, où elle a examiné la répartition des champignons surfaces avant et après le lavage et la désinfection. Dans la composante transversale on été considérés 1 échantillons de 10 gymnases avec des piscines et un autre échantillon de au moins 10 professionnels de chaque établissement dans un total 124 travailleurs (75 hommes - 60,48% et 49 femmes - 39,52%). On a réalisé 258 prélèvements aux pieds des travailleurs et on a effectué en simultané la validation par contamination fongique de l’environnement par 50 prélèvements de l’air et par 120 prélèvements de surfaces (60 avant et 60 après des lavages et des désinfections) et on a effectué leur traitement en laboratoire et l’identification fongique. On a fait aussi l’évaluation des variables de l’environnement, la température, l’humidité relative et la vitesse de l’air. On a remplie 10 tableaux xxix d’observation, avec l’objective d’obtenir des informations sur les variables qu’influenceront l’exposition occupationnel aux souches fongiques, et encore 124 tableaux d’observation liée au prélèvement du matériel biologique, pour réaliser le registre des professionnels avec des lésions et des autres informations pertinentes pour une analyse laboratoire. Tous ces 124 travailleurs ont rempli un questionnaire au même temps que les prélèvements biologiques, afin de connaître quelques variables individuels et professionnels importants pour cet étude. Dans un des établissements on a aussi étudié les différences fongiques des surfaces parmi avant et après les lavages et de la désinfection et encore parmi l’Été et l’Hiver. Dans ce même établissement on a réalisé 36 prélèvements des surfaces avant et 36 après des lavages et de la désinfection, pendant 6 jours différents de la semaine, pendant 6 semaines en chaque saison de l’année, dans un total de 72 prélèvements des surfaces. On a encore crié et appliqué une méthode pour établir un standard d’exposition professionnelle au fungi sur les surfaces, afin de permettre la définition des niveaux semi quantitative d’estimation des risques d’infection fongique des travailleurs des gymnases avec des piscines. Pour le critère de Gravité, il a été considéré que la gravité de la contamination, et donc les possibles dommages, est étroitement liée aux espèces fongiques impliquées. Nous avons calculé la moyenne de la contamination fongique par chaque établissement avant le lavage et la désinfection afin d'établir les niveaux de Fréquence et, par rapport à l'Exposition, ont été crées pour regrouper les intervalles d'heures hebdomadaires consacrées à l'activité professionnelle en question. Sur les 124 travailleurs qui ont participé à l'étude, 58 (46,8%) avaient des lésions visibles. Parmi ces 58, les Levures ont été les plus isolées (41,4%), suivis par des Dermatophytes (24,1%) et des Filamenteux Non Dermatophytes (6,9%). Candida parapsilosis and Rhodotorula sp. ont été les Levures les plus fréquemment isolées (20,2%); dans le cas des Dermatophytes, Trichophyton rubrum est le plus fréquent (55,5%) et pour les Filamenteux Non Dermatophytes, Penicillium sp. a été le plus isolé (15,6%), suivi par Fusarium sp. (12,5%). En ce qui concerne la contamination fongique des surfaces, 37 champignons filamenteux ont été isolés. Le genre Fusarium est le plus fréquent avant et après le lavage et la désinfection (19,1% - 17,2%). Pour la levure, 12 levures différentes ont été identifiées, ayant été Cryptococcus sp. (40,6%) et Candida sp. (49,3%) les plus fréquents avant et après le lavage et la désinfection, respectivement. En ce qui concerne la contamination fongique de l'air, on a identifié 25 différents champignons filamenteux, où les 3 genres les plus fréquemment isolés étaient Cladosporium (36,6%), Penicillium (19,0%) et Aspergillus (10,2%). Pour les levures, il a été identifié le genre xxx Rhodotorula (87,5%) et les espèces Trichosporon mucoides et Cryptococcus unigutulattus (12,5%). On a vérifié une association, au niveau de signification de 5%, entre les lésions visibles et les heures hebdomadaires et entre les lésions visibles et la durée d’occupation, ce qui confirme l'influence de la durée de l'exposition aux facteurs de risque (contamination fongique dans le milieu de travail) pour la présence des lésions visibles chez les travailleurs exposés (Tinea pedis et onychomycose), en démontrant une relation entre l'exposition au facteur de risque dans ces études - l'exposition professionnelle aux champignons - avec les effets sur la santé. Les variables environnementales évalué (température, humidité relative et la vitesse de l'air) ne modifient pas la contamination fongique de l'air et des surfaces; donc, n'a pas été démontré aucune relation statistiquement significative (p>0,05). Cependant, il y a une influence du nombre d'occupants qui ont participé à chacun des établissements en moyenne des unités formant colonie par mètre carré sur la surface avant le lavage et la désinfection. Il n'y avait pas de corrélation entre les résultats quantitatifs de la contamination fongique de l'air et des surfaces des 10 établissements surveillés, cependant il existe des différences importantes, au niveau de signification de 10% entre la contamination fongique des surfaces et de la contamination fongique de l'air (p <0,1), on a constaté que malgré 50% des niveaux les plus bas étaient plus élevés dans la contamination fongique de l'air, la contamination fongique des surfaces présentée une plus grande variabilité quantitativement. En ce qui concerne les différences de la contamination fongique des surfaces dans les 10 établissements entre avant et après le lavage et la désinfection, il y avait seulement une réduction significative (p<0,05) de la contamination fongique après le lavage et la désinfection dans les balnéaires et vestiaires pour les hommes par rapport aux levures. Lors de l'établissement choisi, on a constaté que le rapport entre la contamination fongique et la température et l'humidité relative n'était pas significatif (p>0,05) dans les deux saisons et aussi on n’a pas observé l'influence des occupants en moyenne des unités formant colonie par mètres carrés de surfaces avant le lavage et la désinfection dans les deux saisons de l'année. Dans presque toutes les situations ou on a vérifié des différences significatives entre les deux saisons, il ya eu une augmentation des unités formant des colonies par mètre carré en Hiver, à l'exception du total des unités formant des colonies par mètre carré avant le lavage et désinfection dans les balnéaires et vestiaires des hommes où il y a eu une augmentation en Été. On a également été constaté que seulement a eu une réduction de la contamination des xxxi champignons après la désinfection de l'escalier d'accès en Hiver et dans les balnéaires et vestiaires des hommes en Été. Avec la méthode pour établir standard d’exposition professionnelle au fungi sur les surfaces on a obtenu dans les 10 établissements, avec le Niveau de Risque Faible de 65 places (54,2%), avec le Niveau de Risque Moyen 23 places (19,2%) et 32 places avec le Niveau de Risque Élevé (26,6%). Près du jacuzzi et près de la piscine sont les lieux avec des plus évaluations de Niveau de Risque Élevé. Lors de l'établissement choisi, il a été constaté que, dans l'Été, après le lavage et la désinfection, un plus grand nombre de places évaluées comme présentant un Niveau de Risque Élevé et en Hiver on a constaté la situation inverse avec de nombreux points de Niveau de Risque Élevé avant le lavage et la désinfection. A côté de la piscine et les escaliers ont été les lieux avec plus grands classifications de Niveau de Risque Élevé en Été et en Hiver. On a isolé, chez les travailleurs, des champignons communs aux isolés sur les surfaces. Avant le lavage et la désinfection, 30,3% des champignons ont été isolés sur les travailleurs et sur les surfaces et, après ces procédures, 45,5% des champignons ont été isolés fréquemment. Les levures les plus souvent isolées et les plus fréquentes avant et après le lavage et la désinfection des surfaces, et aussi dans les résultats d'échantillons biologiques prélevés sur les travailleurs, étaient du genre Rhodotorula et les espèces de Candida parapsilosis, ce qui permet confirmer que l'infection fongique des travailleurs est liée à la contamination fongique des surfaces. On a conclu qu’il est nécessaire l'intervention en Santé Occupationnelle sous la surveillance de l'environnement et sous la surveillance de la santé, afin de réduire la prévalence des infections fongiques. Pour atteindre cet objectif, nous suggérons la mise en oeuvre de mesures préventives, y compris: le contrôle de la contamination fongique des surfaces par des méthodes de lavage et de désinfection afin de minimiser la contamination fongique des surfaces, l'identification précoce de l'infection avec des prélèvements biologiques périodiques, notamment un protocole pour la surveillance de la santé, et aussi la conscience du sens de l'hygiène personnelle et le traitement des pathologies. La méthode mise en place pour l’établissement d’un standard d’exposition professionnelle au fungi sur les surfaces, servira à estimer non seulement le risque d'infection fongique des travailleurs dans les gymnases avec des piscines, mais aussi pour faciliter l'établissement de valeurs de référence de champignons, l'application des mesures correctives immédiates et appropriées, et aussi la prévention des infections fongiques, non seulement dans les gymnases avec piscine, mais aussi dans d'autres contextes professionnels.

Sexual transmission of hepatitis C

It is generally agreed that the hepatitis C virus (HCV) can be efficiently transmitted parenterally, although data on viral transmission by sexual or non-sexual intrafamilial contact are conflicting. Since data collection began in 1989, the first study dealt with the risk of sexual transmission among multiple sex partners. Other investigations followed, emphasizing that risk increases in specific groups such as patients co-infected with HIV and HBV, sex workers, homosexuals, illicit drug users and patients attended at sexually transmittable disease clinics. The question arises as to what might be the risk for monogamous heterosexuals in the general population, in which one of the partners has HCV? The literature provides overall rates that vary from zero to 27%; however, most studies affirm that the chances of sexual transmission are low or almost null, with rates for this mode fluctuating from zero to 3%. Intrafamilial transmission is strongly considered but inconclusive, since when mentioning transmission between sex partners within the same household, specific situations also should be considered, such as the sharing of personal hygiene items, like razorblades, toothbrushes, nail clippers and manicure pliers, which are important risk factors in HCV transmission. In this review, we discuss the hypotheses of sexual and/or intrafamilial transmission.

Hepatitis C: sexual or intrafamilial transmission? Epidemiological and phylogenetic analysis of hepatitis C virus in 24 infected couples

The role of sexual or intrafamilial transmission of hepatitis C is controversial. A phylogenetic analysis was performed on the non-structural region 5B of the hepatitis C virus (NS5B-HCV). High percentages of homology (mean of 98.3%) were shown between the couples. Twenty (83.3%) of the 24 men but only two of the women (8.3%) reported having had sexually transmitted diseases during their lives. The risk factors for HCV acquisition were blood transfusion (10 couples), use of illegal injected drugs (17), use of inhalants (15), acupuncture (5) and tattoos (5). The shared use of personal hygiene items included toothbrushes between six couples (25%), razor blades between 16 (66.7%), nail clippers between 21 (87.5%) and manicure pliers between 14 (58.3%). The high degree of similarity of the hepatitis C virus genome supports the hypothesis of hepatitis C virus transmission between these couples. The shared use of personal hygiene items suggests the possibility of intrafamilial transmission of infection.

Caracterização dos beneficiários do Programa De volta para casa de Belo Horizonte/MG/Brasil quanto à autonomia e comportamento social

RESUMO: INTRODUÇÃO E OBJETIVOS: Trata-se de estudo transversal descritivo, em etapa única, cujo objetivo foi traçar o perfil dos beneficiários do Programa De volta para casa (PVC), munícipes de Belo Horizonte / Minas Gerais / Brasil, quanto ás habilidades de vida independente (autonomia) e comportamento social. MÉTODO: O universo inicial de beneficiários era de 210, em julho de 2013, data de aprovação do protocolo. Por questões operacionais, o público-alvo considerado e estudado foi de 121 beneficiários. Foram utilizados como instrumentos as escalas Independent Living Skills Survey (ILSS) e Social Behavior Scale (SBS). Foi feita a análise estatística dos dados e os resultados foram analisados à luz do paradigma emergente de produção social da saúde. RESULTADOS: Considerando o total válido estudado de 121 beneficiários, os resultados revelaram que 82,4% apresentam diagnóstico de esquizofrenia e 62% eram do sexo masculino. Apresentaram média de idade de 57,9 anos e tempo médio de internação psiquiátrica antes de inserção no programa de 30,9 anos. Quanto à autonomia, os resultados da ILSS revelaram uma média global de 1,6 sendo que os melhores índices foram alcançados nos subitens Cuidados pessoais (2,69), Alimentação (2,53), Saúde (2,07) e os piores índices foram encontrados nos subitens Emprego (0,47), Lazer (0,86) e Preparo e armazenamento de alimentos (0,98). Quanto aos problemas no comportamento social, os resultados da SBS revelaram uma média global de 0,69 sendo que as áreas de maiores dificuldade foram: Rir ou falar sozinho (40,5%), Incoerência da fala (29%), Auto-cuidado precário e Pouca atividade (ambas com 25,6% cada). As áreas de menores dificuldades, ainda quanto à SBS, foram: Idéias suicidas 92,4%), Comportamento sexual inapropriado (7,4%) e Depressão (9,9%). CONCLUSÃO: Concluiu-se que o perfil dos beneficiários do PVC, quanto à autonomia e aos problemas de comportamento social, aponta para médias relativamente baixas. O desafio para o enfrentamento desta questão deverá considerar estratégias múltiplas de ação à luz do paradigma emergente de saúde e da reabilitação psicossocial que priorize o empoderamento e protagonismo do beneficiário. É necessário o desenvolvimento de outros estudos que ampliem o evidenciamento desta clientela no que tange às suas reais necessidades e potencialidades para que se possa efetivar o ajuste necessário para a legitimação do programa enquanto ação efetivo-eficaz de promoção de saúde.-------------ABSTRACT: descriptive cross-sectional study in a single stage was conducted to investigate independent living skills and social behavior profile of beneficiaries of Programa De Volta para casa (PVC) who live in Belo Horizonte/Minas Gerais/Brazil. METHODS: The target population included a total of 210 individuals in july 2013, when the study was approved by the ethics committees. Because of operational reasons only 121 individuals were evaluated. Data were collected using the Independent Living Skills Survey (ILSS) and the Social Behavior Scale (SBS). Statistical results were analyzed considering as a reference framework both the emerging paradigm of social health production. RESULTS: Considering a sample of 121 individuals, results revealed that 82.4% were diagnosed with schizophrenia, and 62% were male. The mean age was 57.9 years and the mean stay in the psychiatric hospital prior to PVC was 30.9 years. Independent living skills measured by ILSS revealed a global mean of 1.6, and the best scores were in the following subscales: personal care (2.69), feeding (2.53) and health (2.07). On the other hand, the worst scores were in the following subscales: employment (0.47), leisure (0.86) and food preparation (0.98). Impairment of social functioning measured by SBS revealed a global mean of 0.69, and the best scores were in the following subscales: laughing and talking by itself (40.5%), conversation: incoherence (29%), appearance and personal hygiene (25.6%), and idleness (25.6%). The worst scores were in the following subscales: suicidal ideations (92.4%), improper sexual behavior (7.4%), and depression (9.9%). CONCLUSION: It was concluded that the profile of PVC beneficiaries, regarding their autonomy and their problems of social behavior, points to a relatively low average. The challenge of facing this issue should consider multiple strategies of intervention that prioritizes the empowerment and leadership of the beneficiaries, based on the emerging paradigm of health and psychosocial rehabilitation as a reference framework. The development of other studies that expand the evidencing of this target population with respect to their real needs and capabilities in order to carry out the necessary adjustments for the legitimacy of the program as effective health promotion action is required.

Development and psychometric properties of ECPICID-AVC to measure informal caregivers’ skills when caring for older stroke survivors at home

Introduction: Informal caregivers provide a significant part of the total care needed by dependent older people poststroke. Although informal care is often the preferred option of those who provide and those who receive informal care, informal caregivers often report lack of preparation to take care of older dependent people. This article outlines the development and psychometric testing of informal caregivers’ skills when providing care to older people after a stroke – ECPICID-AVC. Design: Prospective psychometric instrument validation study. Methods: Eleven experts participated in a focus group in order to delineate, develop and validate the instrument. Data were gathered among adult informal caregivers (n = 186) living in the community in Northern Portugal from August 2013 to January 2014. Results: The 32-item scale describes several aspects of informal caregiver’s skills. The scale has eight factors: skill to feed/hydrate by nasogastric feeding, skill to assist the person in personal hygiene, skill to assist the person for transferring, skill to assist the person for positioning, skill to provide technical aids, skill to assist the person to use the toilet, skill to feed/hydrate and skill to provide technical aids for dressing/undressing. Analysis demonstrated adequate internal consistency (Cronbach’s alpha = 0.83) and good temporal stability 0.988 (0.984–0.991). Conclusion: The psychometric properties of the measurement tool showed acceptable results allowing its implementation in clinical practice by the nursing community staff for evaluating practical skills in informal caregivers when providing care to older stroke survivors living at home.

The frequency of Toxocara infection in mental retarded children

Human toxocariasis is commonly seen in places where stray and Toxocara canis-infected dog population is high. There is a strong correlation between frequency of Toxocara infection, life style, and infection risk. Institutionalization of mental retarded patients increases to risk of toxocariasis. In this study, we aimed at investigating the frequency of Toxocara infection among children with mental retardation not requiring institutionalization. The study included 96 cases, who had educatable mental retardation and 85 healthy subjects who comprised the control group. Anti-Toxocara IgG or IgM antibodies were investigated in all serum samples, using ELISA method. The frequency of Toxocara infection was found significantly higher in mental retarded cases than in those in the control group (18.8% and 7.1% respectively) (p < 0.05). There was no significant difference between mental retarded children and the control group in terms of mean age, age groups, gender, owning dogs and cats and duration of their ownership, socio-economic level and behavioural factors, and personal hygiene (p > 0.05). We did not find any significant difference between Toxocara seropositive and seronegative mental retarded children in terms of demographic factors and epidemiological factors that could increase the risk of Toxocara infection (p > 0.05). The present study is the first seroprevalence study carried out with a mental retarded group not requiring institutionalization. Determination of high frequency of Toxocara infection suggests that these subjects constitute a risk factor for Toxocara infection, which may be attributed to their behavioural patterns.

Questioni di pulizia: rappresentazioni e valori

In the framework of social representation, this research explores how the concept of cleanness does not refer solely to individual hygienic praxes and thoughts, but it is also linked to social and cultural aspects. In this way, the definitions of what is dirty and what is clean, what is pure and what is impure, are linked to social discrimination attitudes, based for example on the fear for contamination. Our general hypothesis is that the representations of dirt/cleanness and purity/impurity define ideas and praxes linked to personal hygiene, but refer also to the way people interact with the world and the others. Hence, we hypothesize that the representations of dirt/cleanness and purity/impurity are linked to values and political and religious orientations. A questionnaire with closed-answer questions and a free association task were distributed to 450 subjects. Results show how, in effects, the concepts of dirt/cleanness, purity/ impurity skip from their daily praxis connotations and assume a symbolic function for discriminating between individuals and social groups.

Pollution of air, water and soil by industrial chemicals presents a potential health risk to humans. Such chemicals can enter the human body by three routes, namely by inhalation, dermal absorption, and ingestion and in special cases by injection (needle sticks, bites, cuts, etc.). In the workplace, pulmonary and dermal absorption are the main routes of entry, but poor personal hygiene and work habits can result in ingestion that contributes to the dose. Air monitoring provides reliable information on inhalation exposure, and patches can be used to estimate dermal exposure. Local adverse effects, such as skin and eye irritation, or nose and lung irritation, are closely related to the external exposure. Systemic adverse effects, on the other hand, are related to the absorbed amount (dose), or to the level of the pollutant or its metabolite in the target organ. Human biological monitoring is becoming a powerful tool for scientists and policy makers to assess and manage the risk of exposure to chemicals both in the general population and at the workpalce. This chapter will focus on the occupational environment keeping in mind that biological monitoring in humans is a very actual issue in public health politics, in environmental medicine, and in science in general.

Occupational therapy in spinocerebellar ataxia type 3: an open-label trial

Occupational therapy (OT) is a profession concerned with promoting health and well-being through occupation, by enabling handicapped people to participate in the activities of everyday life. OT is part of the clinical rehabilitation of progressive genetic neurodegenerative diseases such as spinocerebellar ataxias; however, its effects have never been determined in these diseases. Our aim was to investigate the effect of OT on both physical disabilities and depressive symptoms of spinocerebellar ataxia type 3 (SCA3) patients. Genomically diagnosed SCA3 patients older than 18 years were invited to participate in the study. Disability, as evaluated by functional independence measurement and Barthel incapacitation score, Hamilton Rating Scale for Depression, and World Health Organization Quality of Life questionnaire (WHOQOL-BREF), was determined at baseline and after 3 and 6 months of treatment. Twenty-six patients agreed to participate in the study. All were treated because OT prevents blinding of a control group. Fifteen sessions of rehabilitative OT were applied over a period of 6 months. Difficult access to food, clothing, personal hygiene, and leisure were some of the main disabilities focused by these patients. After this treatment, disability scores and quality of life were stable, and the Hamilton scores for depression improved. Since no medication was started up to 6 months before or during OT, this improvement was related to our intervention. No association was found between these endpoints and a CAG tract of the MJD1 gene (CAGn), age, age of onset, or neurological scores at baseline (Spearman test). Although the possibly temporary stabilization of the downhill disabilities as an effect of OT remains to be established, its clear effect on depressive symptoms confirms the recommendation of OT to any patient with SCA3 or spinocerebellar ataxia.
