Forest fires occurrences and burned area in mainland Portugal: preliminary assessment to a fifteen years period

Portugal, as well as the Mediterranean basin, is favorable to the occurrence of forest fires. In this work a statistical analysis was carried out based on the official information, considering the forest fires occurrences and the corresponding burned area for each of the districts of the mainland Portugal, between 1996 and 2010. Concerning to the forest fires occurrence it was possible to identify three main regions in mainland Portugal, while the burned area can be characterized in two main regions. Associations between districts and years are different in the two approaches. The results obtained provide a synthetic analysis of the phenomenon of forest fires in continental Portugal, based on all the official information available to date.

Cork stoppers industry: defining appropriate mould colonization

Aims: The main aims of this work were the study of cork slabs moulds colonization and the evaluation of the moulds diversity during cork processing steps, in different cork stoppers factories. Simultaneously, it was envisaged to perform an evaluation of the air quality. Methods and Results: Moulds were isolated and identified from cork slabs and cork samples in four cork stoppers factories. The identification was based on morphological characters and microscopic observation of the reproductive structures. Airborne spore dispersion was assessed using a two stage Andersen sampler. It was observed that Chrysonilia sitophila was always present on cork slabs during the maturing period, but mould diversity appeared to be associated to the different factory configurations and processing steps. Conclusions: Spatial separation of the different steps of the process, including physical separation of the maturation step, is essential to guarantee high air quality and appropriate cork slabs colonization, i.e. C. sitophila dominance. The sorting and cutting of the edges of cork slabs after boiling and before the maturing step is also recommended. Significance and Impact of the Study: This study is very important for the cork stopper industry as it gives clear indications on how to keep high quality manufacturing standards and how to avoid occupational health problems.

Sedimentation in parasitological coproscopy

A sedimentation technique is described, in which a fecal suspension is placed on top of an aqueous sucrose solution of specific gravity 1.015 g/cm³. Using 100 by 15 mm test tubes, duplicate gravity sedimentation experiments were made using homogenized fecal suspensions (single-columns) and fecal suspensions placed on top of clear columns (double-columns). Egg- and cyst-counts, and turbidity determinations were made in the sediments obtained after definite time intervals. Most Ascaris lumbricoides, Trichuris trichiura and Ancylostomidae eggs sedimented within 20 minutes in single - and between 30 and 60 minutes in double-columns. Giardia duodenalis cysts required longer periods to sediment in double - than in single-columns; after 180 minutes (the maximum period of observation), double-column sediments produced 60.0% of the counts of single-columns. Double-column sediments were consistently less turbid than single-column ones

Efeito da exposição às temperaturas extremas na população portuguesa - um contributo da epidemiologia

Backgroud: O International Panel on Climate Change prevê que o aumento da temperatura média global, até ao ano de 2100, varie entre 1,4 e 5,8ºC desconhecendo-se a evolução da adaptação da população a esta subida da temperatura. Em Portugal morre-se mais no Inverno que no Verão. Mas existem evidências de repercussões na mortalidade atribuíveis ao calor extremo. Este estudo procura conhecer os grupos etários e/ou populacionais que parecem revelar vulnerabilidade acrescida à exposição a temperaturas extremas e identificar indicadores de saúde apropriados para revelar esses mesmos efeitos. Métodos: Foram analisados dados de internamentos hospitalar e mortalidade por doenças cardiovasculares, respiratórias, renais, efeitos directos do frio e do calor, na população com 75 e mais anos de idade, nos distritos de Beja, Bragança e Faro, nos meses de Janeiro e Junho. Para os dados de morbilidade o período de análise foi 2002 a 2005 e para os de mortalidade de 2002 a 2004. Os dados meteorológicos analisados corresponderam aos valores da temperatura máxima e percentis da temperatura máxima, nos meses de Janeiro (P10) e Junho (P90). Os excessos de internamentos hospitalares, definidos como os dias em que ocorreram internamentos acima do valor da média mais 2 desvio padrão, foram relacionados com a distribuição das temperaturas extremas (frias abaixo do P10, quentes acima do P90.Os dias com óbitos acima do valor da média foram relacionados com a distribuição das temperaturas extremas (frias abaixo do P10, quentes acima do P90). Os indicadores propostos foram baseados em Odds Ratios e intervalos de confiança que sugeriam as estimativas mais precisas. Resultados: O grupo que revelou maior vulnerabilidade às temperaturas extremas foi o grupo dos 75 e mais anos, com doenças cardiovasculares quando exposto a temperaturas extremas, nos 3 distritos observados.O nº de dias de excesso de óbitos por doenças cardiovasculares relacionados com temperaturas extremas foi o mais elevado comparado com as restantes causas de morte. O grupo etário dos 75 e mais anos com de doenças respiratórias também é vulnerável, às temperaturas extremas frias, nos 3 distritos. Verificaram-se dias de excessos de internamentos hospitalares e óbitos por esta causa de morte, relacionados com a exposição às temperaturas extremas frias. Em Junho, não se verificou excesso de mortalidade associado à exposição a temperaturas extremas por esta causa, em qualquer dos distritos analisados. Apenas se verificou a associação entre os dias de ocorrência de internamentos hospitalares por doenças renais e o calor extremo, em Bragança. Conclusões: Foram encontradas associações estatísticas significativas entre dias de excesso de ocorrência de internamentos hospitalares ou óbitos por causa e exposição a temperaturas extremas frias e quentes possibilitando a identificação de um conjunto de indicadores de saúde ambiental apropriados para monitorizar a evolução dos padrões de morbilidade, mortalidade e susceptibilidade das populações ao longo do tempo.-------------------- Backgroud: International Panel on Climate Change estimates that the rise of mean global temperature varies between 1,4 e 5,8ºC until 2100, with unknowing evolution adaptation of populations. In Portugal we die more in Winter than in Summer time. But there are several evidences of mortality attributable to extreme eat. The proposal of this study is to know the age and/or populations groups that reveal more vulnerability to exposure to extreme temperature and identifying proper health indicators to reveal those effects. Methods: Data from hospital admissions and mortality caused by cardiovascular, respiratory, renal diseases and direct effects from direct exposure to extreme cold and heat, in population with 75 and more years, in Beja, Bragança and Faro districts, during January and June, were analysed. Analysis period for morbidity data was from 2002 to 2005 and form mortality was 2002 to 2004. Meteorological data analysed were maximum temperature and percentile of maximum temperature, from January (P10) and June (P90. Relationship between excess of hospital admission, defined as the days that occurred hospital admissions above mean value more 2 standards desviation and distribution of extreme temperatures were established (cold under P10 and heat above P90. Proposal indicators were based on Odds Ratios and confidence intervals, suggesting the most precises estimatives. Results: The most vulnerable group to extreme temperature were people with 75 or more years older with cardiovascular diseases, observed in the 3 districts. Number of days caused by excess cardiovascular mortality and extreme temperature were the most number of days between the other causes. The group with 75 or more years old with respiratory diseases is vulnerable too, especially to cold extreme temperature, in all the 3 districts. There were excess of days of hospital admissions and days with deaths, for this cause relating to extreme cold temperature. In June, does not funded excess of mortality associated to extreme temperature by this cause in any district of the in observation. Just was found relationship between days of hospital admissions caused by renal diseases in Bragança in days with extreme heat. Conclusions: Were found statistically significant associations between days of excess of hospital admissions or deaths and exposure to extreme cold and heat temperatures giving the possibility of identifying a core of environmental indicators proper to monitoring patterns and trends evolutions on morbidity, mortality and susceptibly of populations for a long time.

Age-period-cohort effects in the incidence of hip fractures: political and economic events are coincident with changes in risk

Introduction: Healthcare improvements have allowed prevention but have also increased life expectancy, resulting in more people being at risk. Our aim was to analyse the separate effects of age, period and cohort on incidence rates by sex in Portugal, 2000–2008. Methods: From the National Hospital Discharge Register, we selected admissions (aged ≥49 years) with hip fractures (ICD9-CM, codes 820.x) caused by low/moderate trauma (falls from standing height or less), readmissions and bone cancer cases. We calculated person-years at risk using population data from Statistics Portugal. To identify period and cohort effects for all ages, we used an age–period–cohort model (1-year intervals) followed by generalised additive models with a negative binomial distribution of the observed incidence rates of hip fractures. Results: There were 77,083 hospital admissions (77.4 % women). Incidence rates increased exponentially with age for both sexes (age effect). Incidence rates fell after 2004 for women and were random for men (period effect). There was a general cohort effect similar in both sexes; risk of hip fracture altered from an increasing trend for those born before 1930 to a decreasing trend following that year. Risk alterations (not statistically significant) coincident with major political and economic change in the history of Portugal were observed around birth cohorts 1920 (stable–increasing), 1940 (decreasing–increasing) and 1950 (increasing–decreasing only among women). Conclusions: Hip fracture risk was higher for those born during major economically/politically unstable periods. Although bone quality reflects lifetime exposure, conditions at birth may determine future risk for hip fractures.

Legionnaires' disease in the renal transplant unit of "Hospital das Clinicas, FMUSP": during a five year period (1988-1993)

Several reports have related Legionella pneumophila with pneumonia in renal transplant patients, however this association has not been systematically documented in Brazil. Therefore this paper reports the incidence, by serologycal assays, of Legionella pneumophila serogroup 1 in these patients during a five year period. For this purpose sera from blood samples of 70 hospitalized patients with pneumonia from the Renal Transplant Unit of Hospital das Clinicas, FMUSP collected at the acute and convalescent phase of infection were submitted to indirect immunofluorescence assay (IFA) to demonstrate anti-Legionella pneumophila serogroup 1 antibodies. Of these 70 patients studied during the period of 1988 to 1993,18 (25.71 %) had significant rises in specific antibody titers for Legionella pneumophila serogroup 1. Incidence was interrupted following Hospital water decontamination procedures, with recurrence of infections after treatment interruption. In this study, the high susceptibility (25.71%) of immunodepressed renal transplant patients to Legionella pneumophila serogroup 1 nosocomial infections is documented. The importance of the implementation and maintenance of water decontamination measures for prophylaxis of the infection is also clearly evident.
