Internamentos hospitalares da população com mais de 65 anos em Portugal – Análise Descritiva

RESUMO - As mudanças na saúde são cada vez mais rápidas e os serviços de saúde têm cada vez mais dificuldade em dar resposta aos problemas de saúde dos portugueses. Responsáveis por grande parte da despesa em saúde, os idosos são a população que mais utiliza os serviços de saúde e as respetivas unidades hospitalares e serviços de urgência. Estes têm estadias mais prolongadas e consomem mais recursos durante essas permanências nas instituições de saúde. Sabendo isto revelou-se oportuno encontrar as principais causas de internamento hospitalar, os principais diagnósticos secundários, demoras médias e a sua relação com as principais causas de morte na população portuguesa com mais de 65 anos no período de 2003-2012. Para tal, optou-se por uma análise descritiva de 3375817 episódios de internamento referentes a dez anos. Daqui retirou-se que os diagnósticos principais mais frequentes para todos os anos e todas as faixas etárias são o acidente vascular cerebral isquémico e a pneumonia, sendo que o primeiro é o mais frequente até 2006, passando depois a ser a pneumonia o mais frequente. A demora média é maior quanto mais diagnósticos secundários associados houver e aumenta com a idade. Os diagnósticos secundários mais frequentes são a hipertensão essencial e a diabetes mellitus. Estes dados são relevantes para o conhecimento da saúde em Portugal, podendo-se alterar e uniformizar e melhorar práticas hospitalares e com isso progredir na qualidade dos tratamentos e aumentar a qualidade de vida com hipótese de diminuição da demora média.

Device-specific weighted T-score for two quantitative ultrasounds: operational propositions for the management of osteoporosis for 65 years and older women in Switzerland.

The World Health Organization (WHO) criteria for the diagnosis of osteoporosis are mainly applicable for dual X-ray absorptiometry (DXA) measurements at the spine and hip levels. There is a growing demand for cheaper devices, free of ionizing radiation such as promising quantitative ultrasound (QUS). In common with many other countries, QUS measurements are increasingly used in Switzerland without adequate clinical guidelines. The T-score approach developed for DXA cannot be applied to QUS, although well-conducted prospective studies have shown that ultrasound could be a valuable predictor of fracture risk. As a consequence, an expert committee named the Swiss Quality Assurance Project (SQAP, for which the main mission is the establishment of quality assurance procedures for DXA and QUS in Switzerland) was mandated by the Swiss Association Against Osteoporosis (ASCO) in 2000 to propose operational clinical recommendations for the use of QUS in the management of osteoporosis for two QUS devices sold in Switzerland. Device-specific weighted "T-score" based on the risk of osteoporotic hip fractures as well as on the prediction of DXA osteoporosis at the hip, according to the WHO definition of osteoporosis, were calculated for the Achilles (Lunar, General Electric, Madison, Wis.) and Sahara (Hologic, Waltham, Mass.) ultrasound devices. Several studies (totaling a few thousand subjects) were used to calculate age-adjusted odd ratios (OR) and area under the receiver operating curve (AUC) for the prediction of osteoporotic fracture (taking into account a weighting score depending on the design of the study involved in the calculation). The ORs were 2.4 (1.9-3.2) and AUC 0.72 (0.66-0.77), respectively, for the Achilles, and 2.3 (1.7-3.1) and 0.75 (0.68-0.82), respectively, for the Sahara device. To translate risk estimates into thresholds for clinical application, 90% sensitivity was used to define low fracture and low osteoporosis risk, and a specificity of 80% was used to define subjects as being at high risk of fracture or having osteoporosis at the hip. From the combination of the fracture model with the hip DXA osteoporotic model, we found a T-score threshold of -1.2 and -2.5 for the stiffness (Achilles) determining, respectively, the low- and high-risk subjects. Similarly, we found a T-score at -1.0 and -2.2 for the QUI index (Sahara). Then a screening strategy combining QUS, DXA, and clinical factors for the identification of women needing treatment was proposed. The application of this approach will help to minimize the inappropriate use of QUS from which the whole field currently suffers.

Low prevalence of abdominal aortic aneurysm in the Seychelles population aged 50 to 65 years.

The prevalence of abdominal aortic aneurysm (AAA) and its risk factors are well known in Western countries but few data are available from low- and middle- income countries. We are not aware of systematically collected population- based data on AAA in the African region. We evaluated the prevalence of AAA in a population- based cardiovascular survey conducted in the Republic of Seychelles in 2004 (Indian Ocean, African region). Among the 353 participants aged 50 to 64 years and screened with ultrasound, the prevalence of AAA was 0.3% (95% CI: 0- 0.9) and the prevalence of ectatic dilatations of the abdominal aorta was 1.5% (95% CI: 0.2- 2.8). The prevalence of AAA in the general population seemed lower in Seychelles than in Western countries, despite a high prevalence in Seychelles of risk factors of AAA, such as smoking (in men), high blood pressure and hypercholesterolaemia.

La repercussió de l'onada de calor de 2003 en la població major de 65 anys de Barcelona i l'àrea metropolitana

Les onades de calor eren un fenomen desconegut per la població fins fa pocs anys, i tot i que avui dia ja son més populars, les seves conseqüències passen molt més desapercebudes que la d’altres catàstrofes naturals. En aquest estudi, a partir de l’episodi que va patir la península durant l’agost de 2003, es pretén aprofundir en els factors que van fer propiciar que la mortalitat entre les persones majors de 65 anys augmentés de manera notable en comparació amb anys anteriors. Els resultats de l’estudi mostren que un dels grups més vulnerables son les persones grans que viuen soles i per tant caldria tenir en compte aquest factor a l’hora de fer plans d’acció, així com també que els pics de màxima mortalitat es corresponen amb dies posteriors als de la pujada de temperatura, ja que aquesta agreuja patologies prèvies de les persones i moren temps després. També seria interessant un consens internacional a l’hora d’establir uns criteris estàndards per tal de tenir així uns registres més fiables que permetin extreure noves mesures per lluitar contra les onades de calor.

¿Qué ocurre con el déficit de vitamina d en la población general mayor de 65 años después del verano?

Estudi d’una cohort de persones majors de 64 anys ateses en 5 Àrees Bàsiques de Salut del Vallès Occidental, a les que es van determinar els nivells de vitamina D desprès de l’estiu, per analitzar la possible existència d’una variació estacional en el seu estat vitamínic, i els factors associats. Es van comparar els resultats amb les dades obtingudes en un estudi previ realitzat desprès de l’hivern. Es manté una elevada prevalença d’hipovitaminosi D en aquesta població desprès de l’estiu. Els factors associats amb la deficiència vitamínica van ser els nivells basals previs de 25(OH)D3 i la menor exposició solar.

A quick, free scan for all men aged 65+

The Northern Ireland Abdominal Aortic Aneurysm (AAA) Screening Programme began in June 2012 and offers AAA screening to all men aged 65 and over in Northern Ireland. All men in their 65th year receive an invite in the post. All men aged over 65 who have not been screened can request an appointment. The aim of the AAA screening programme is to reduce AAA-related mortality by providing systematic, population-based screening.� This poster was sent out to all GPs, GP practice managers and pharmacies as part of a professional information pack in the run-up to the launch of the programme. The poster is also distributed to relevant voluntary organisations and charities as a means of raising awareness among the target population.

Energy cost of walking and gait instability in healthy 65- and 80-yr-olds.

This study tested whether the lower economy of walking in healthy elderly subjects is due to greater gait instability. We compared the energy cost of walking and gait instability (assessed by stride to stride changes in the stride time) in octogenarians (G80, n = 10), 65-yr-olds (G65, n = 10), and young controls (G25, n = 10) walking on a treadmill at six different speeds. The energy cost of walking was higher for G80 than for G25 across the different walking speeds (P < 0.05). Stride time variability at preferred walking speed was significantly greater in G80 (2.31 +/- 0.68%) and G65 (1.93 +/- 0.39%) compared with G25 (1.40 +/- 0.30%; P < 0.05). There was no significant correlation between gait instability and energy cost of walking at preferred walking speed. These findings demonstrated greater energy expenditure in healthy elderly subjects while walking and increased gait instability. However, no relationship was noted between these two variables. The increase in energy cost is probably multifactorial, and our results suggest that gait instability is probably not the main contributing factor in this population. We thus concluded that other mechanisms, such as the energy expenditure associated with walking movements and related to mechanical work, or neuromuscular factors, are more likely involved in the higher cost of walking in elderly people.

Altered expression of beta-galactosidase-1-like protein 3 (Glb1l3) in the retinal pigment epithelium (RPE)-specific 65-kDa protein knockout mouse model of Leber's congenital amaurosis

Purpose: In this study, we investigated the expression of the gene encoding beta-galactosidase (Glb)-1-like protein 3 (Glb1l3), a member of the glycosyl hydrolase 35 family, during retinal degeneration in the retinal pigment epithelium (RPE)-specific 65-kDa protein knockout (Rpe65(-/-)) mouse model of Leber congenital amaurosis (LCA). Additionally, we assessed the expression of the other members of this protein family, including beta-galactosidase-1 (Glb1), beta-galactosidase-1-like (Glb1l), and beta-galactosidase-1-like protein 2 (Glb1l2).Methods: The structural features of Glb1l3 were assessed using bioinformatic tools. mRNA expression of Glb-related genes was investigated by oligonucleotide microarray, real-time PCR, and reverse transcription (RT) -PCR. The localized expression of Glb1l3 was assessed by combined in situ hybridization and immunohistochemistry.Results: Glb1l3 was the only Glb-related member strongly downregulated in Rpe65(-/-) retinas before the onset and during progression of the disease. Glb1l3 mRNA was only expressed in the retinal layers and the RPE/choroid. The other Glb-related genes were ubiquitously expressed in different ocular tissues, including the cornea and lens. In the healthy retina, expression of Glb1l3 was strongly induced during postnatal retinal development; age-related increased expression persisted during adulthood and aging.Conclusions: These data highlight early-onset downregulation of Glb1l3 in Rpe65-related disease. They further indicate that impaired expression of Glb1l3 is mostly due to the absence of the chromophore 11-cis retinal, suggesting that Rpe65 deficiency may have many metabolic consequences in the underlying neuroretina.
