The impact of dementia on informal or family caregivers became a public health issue. One well-established tool for the assessment of emotional, physical and social impact on caregivers is the Zarit Burden Interview. Worldwide, it is widely used in epidemiological studies, drug or psychosocial clinical trials, and health services research. The original focus on burden among dementia caregivers has spread to oth...
RESUMO: Introdução: A hipótese colocada nesta tese é a de que poderia haver um número bastante mais elevado de ensaios clÃnicos na medicina familiar portuguesa se os obstáculos fossem removidos e as oportunidades exploradas de modo adequado. Contexto: Em Portugal existe uma nova geração de Médicos de FamÃlia que está a assumir postos de trabalho um pouco por todo o paÃs e que é aceite como sendo a...
This study combines geochemical and geochronological data in order to decipher the provenance of Carboniferous turbidites from the South Portuguese Zone (SW Iberia). Major and trace elements of 25 samples of graywackes and mudstones from the Mértola (Visean), Mira (Serpukhovian), and Brejeira (Moscovian) Formations were analyzed, and 363 U-Pb ages were obtained on detrital zircons from five samples of graywacke...
The areas of the counties of Estremoz, Borba and Vila Viçosa, traditionally and since ancient times, have been a major region for extraction of marbles for use as a dimension stone in Portugal. The geological evolution of the Iberian Peninsula allowed the formation, in Alto Alentejo, of one of the World’s most important and famous marble deposits. The Estremoz Anticline, about 42 km long and 8 km in maximum wid...
This study makes a comparison of the populations of detrital zircon from Late Ediacaran greywackes of the Ossa-Morena Zone (OMZ) and the southern domains of the Central Iberian Zone (S-CIZ). The results obtained reveal that the main difference between the age spectra of both populations of detrital zircon is the Neoproterozoic, in particularly the Cryogenian grains. Our new data suggest that deposition in both ...
This study makes a comparison between the populations of detrital zircon of the Cambrian sandstones from the Ossa-Morena Zone (OMZ) and the Ordovician quartzites from the southern domains of the Central Iberian Zone (S-CIZ) in order to identify the sources during development of North Gondwana basins (SW Iberia). The U-Pb results obtained for the Lower Cambrian sandstones of the OMZ show a remarkable similarity ...
