BACKGROUND Asthma is a frequent chronic respiratory disease in both children and adults. However, few data on asthma prevalence are available in Portugal. The Portuguese National Asthma Survey is the first nationwide study that uses standardized methods. We aimed to estimate the prevalence of current asthma in the Portuguese population and to assess the… (More)
Objective To evaluate the psychometric properties of the Oral Heath Impact Profile (OHIP-14) to measure oral health in children.
The current fire regime threatens black pine (Pinus nigra Arn.) persistence in the Mediterranean Basin, which recommends larger-scale fuel treatments. Prescribed burning is an option for stand protection but its use in young stands (which are particularly at risk) is hindered by the scarce knowledge on post-fire tree survival. The objectives were to… (More)
OBJECTIVE To evaluate the psychometric properties of the Oral Heath Impact Profile (OHIP-14) to measure oral health in children. METHODS The OHIP-14 questionnaire was applied to 312 schoolchildren aged 12 years residing in Sabará, Brazil, in 2001. OHIP-14's reliability was evaluated using Cronbach's alpha and correlation intraclass coefficient. For… (More)
BACKGROUND Fruits and vegetables are rich in compounds with proposed antioxidant, anti-allergic and anti-inflammatory properties, which could contribute to reduce the prevalence of asthma and allergic diseases. OBJECTIVE We investigated the association between asthma, and chronic rhino-sinusitis (CRS) with intake of fruits and vegetables in European… (More)
Large fires and their impacts are a growing concern as changes in climate and land use proceed. The study of large-fire controls remains incipient in comparison with other components of the fire regime. Improved understanding of large-fire size drivers can disclose fire–landscape relationships and inform more sustainable and effective fire management. We… (More)
Eosinophilic esophagitis (EoE) is an inflammatory disease characterized by eosinophilic infiltration of the eso-phageal wall. It is an increasingly recognized disease that affects mostly caucasian males in two peaks of incidence: 5-10/20-40 years. Studies show that more than 90% of this patients are sensitized to mite or polens, 50% to food, and that the… (More)
OBJECTIVE To evaluate the validity of the Qualis database in identifying the levels of scientific evidence and the quality of randomized controlled trials indexed in the Lilacs database. METHODS We selected 40 open-access journals and performed a page-by-page hand search, to identify published articles according to the type of study during a period of six… (More)
