Global geriatric evaluation of the Algarve population

The ageing of population challenges communities to adapt and evolve to accommodate the needs of people that live longer (mostly out of work, either healthy, fragile or with chronic disease). Population ageing in the Algarve is higher than in overall Portugal. Studies on health conditions, frailty risk factors and elderly specific needs are undeveloped in Portugal and unknown in the Algarve. Objective To prepare a tool for Global Geriatric Evaluation, to be used in the “Survey of Health and Ageing in the Region of Algarve - SHARA”, a commitment to “European Innovation Partnership on Active and Healthy Ageing”. Methods A preliminary version of the screening tool, which includes well-known instruments to measure health condition (EASY-care), risk of fall (Tinetty), physical activity (Baecke’s modified questionnaire), nutritional condition (MNA), cognitive and depressive status (MMSE, Yesavage geriatric depression scale), together with socio-demographic characteristics, was applied to an independent sample of subjects from an elderly community centre - ARPI (“Associação de Reformados, Pensionistas e Idosos do Concelho de Faro”), with ages between 55 and 89. Results ARPI is mostly frequented by women, who either have risk of malnutrition or malnutrition incidence, a relevant risk of fall or are physically active. Those who live alone, show a higher risk of fall. Conclusions ARPI members are active, but with risk of malnutrition and fall, suggesting the relevance and importance of future interventions in these areas. The proposed screening tool showed to be adequate for the SHARA study, suitable to provide wider information on frailty.

Characterization of 10 new tetranucleotide microsatellite markers for the European eagle owl, Bubo bubo: Useful tools for conservation strategies

Bubo bubo is the largest owl in the world, showing a wide geographical distribution throughout the Palaearctic region. It underwent a demographic decline in many European countries during the last century and was considered “vulnerable” (Annex II of the CITES). Nowadays, it is classified as “Least Concern” according to IUCN. Despite its ecological importance and conservation status, few polymorphic molecular markers are available to study its diversity and population genetics. We report on the isolation and development of 10 new microsatellites for the Eagle owl, B. bubo. All loci (10 tetra-nucleotide) are characterized by high polymorphism levels. Number of alleles ranged from 5 to 13 and expected heterozygosity varied from 0.733 to 0.840. These microsatellites would be very useful to assess the genetic diversity, connectivity patterns and parentage of B. bubo. This information will allow to establish new conservation strategies and improve the management of the species.
