[Analysis of the effect of a program of cognitive stimulation in elderly people with normal aging in primary care: Randomized clinical trial]. / Análisis del efecto de un programa de estimulación cognitiva en personas con envejecimiento normal en Atención Primaria: ensayo clínico aleatorizado.

OBJECTIVE: To provide evidence of the effectiveness of a community health intervention, that includes a cognitive stimulation program, to prevent the deterioration of cognitive abilities in our population of elderly people with normal cognition that are living in the community. DESIGN: Randomized clinical trial (CONSORT group norms) LOCATION: San José Norte-Centro Health Center and La Caridad Foundation (Zaragoza, Spain). PARTICIPANTS: 201 people aged 65 or older, with a MEC score of at least 28 points, which were randomized between the Intervention group (101) and the Control group (100). INTERVENTION: The intervention was applied in 10 sessions of 45minutes, one per week. It used materials designed by one of the authors, which addressed the following areas: memory, orientation, language, praxis, gnosis, calculation, perception, logical reasoning, attention-concentration and programming. MAIN MEASUREMENTS: The main outcome variables were MEC, Set-Test, Barthel and Lawton-Brody. RESULTS: Increases of the main result variables over their baseline level were analized. For MEC variable, the Intervention group obtained, on average, 1.58 points more than the Control group in the evaluation performed immediately after the intervention. After 6months, the improvement was 1.51 points and after a year, it was of 2.04 points. All these differences were statistically significant. For Set-Test, Barthel and Lawton-Brody variables, no statistically significant differences were observed between Intervention group and Control group. CONCLUSIONS: Cognitive stimulation with our program is effective to maintain or improve cognitive performance, measured with the variable MEC, our population of elderly people with normal cognition that are living in the community. There is no evidence that this improvement is transferred to the activities of daily life measured with Barthel and Lawton-Brody variables.

Accurate Measurements of Spectral Reflectance in Picasso's Guernica Painting.

The use of non-invasive spectral measurements to control the conservation status is a part of the preventive conservation of artworks which nowadays is becoming increasingly interesting. This paper describes how to use a spectral measuring device and an illumination system specifically designed for such a task in a very large dimension artwork painting (7.8 m wide × 3.5 m high). The system, controlled by a Cartesian robot, allows spectral measurements in a spectral range of 400-780 nm. The measured data array has a total of 2201 circular regions with 5.5 mm spot diameter placed on a square grid. Colorimetric calculations performed from these spectral measurements may be used to characterize color shifts related to reflectance changes in specific areas of the paint. A color shifting from the expected gray has been shown.

The validity of the 12-item Bem Sex Role Inventory in older Spanish population: an examination of the androgyny model.

The Bem Sex Role Inventory (BSRI) is the most commonly used and validated gender role measurement tool across countries and age groups. However, it has been rarely validated in older adults and sporadically used in aging and health studies. Perceived gender role is a crucial part of a person's identity and an established determinant of health. Androgyny model suggests that those with high levels of both masculinity and femininity (androgynous) are more adaptive and hence have better health. Our objectives were to explore the validity of BSRI in an older Spanish population, to compare different standard methods of measuring gender roles, and to examine their impact on health indicators. The BSRI and health indicator questions were completed by 120 community-dwelling adults aged 65+ living in Aragon, Spain. Exploratory factor analysis was performed to examine psychometric properties of the BSRI. Androgyny was measured by three approaches: geometric mean, t-ratio, and traditional four-gender groups classification. Relationships between health indicators and gender roles were explored. Factor analysis resulted in two-factor solution consistent with the original masculine and feminine items with high loadings and good reliability. There were no associations between biological sex and gender roles. Different gender role measurement approaches classified participants differently into gender role groups. Overall, androgyny was associated with better mobility and physical and mental health. The traditional four groups approach showed higher compatibility with the androgyny model and was better able to disentangle the differential impact of gender roles on health.

[Creation of a unit for education in the self-management of oat]. / Creación de una unidad de educación en el autocontrol del TAO.

Oral anticoagulant therapy (OAT) with Vitamin K antagonists requires frequent analytical controls that create a certain degree of dependency and a loss of autonomy in the patient. These drugs have an undesirable variability due to food and drug interactions, febrile processes, etc. which can modify the patient's INR and predispose them to a thromboembolic or hemorrhagic event. OAT self-control is supported by more than 15 years of experience in countries such as Germany and the Netherlands, and by comparative studies that reflect a reduction of thromboembolism and other adverse effects. The reason of this is because these patients are in the correct therapeutic range for longer periods of time due to more frequent controls (once a week against every 4-5 weeks of traditional control) and also to a better understanding of their treatment. In Aragon, OAT is a free health service and in our hospital, OAT has been an institutional aim since 2070. After a training course, the patient is capable to make their own INR determinations at home, to evaluate their results and adjust their own dose. Additionally the patient should acquire the appropriate knowledge to detect any adverse symptom and to know how to react to any problem in their treatment. This article summarizes our experience regarding the implementation of the programme and creation of the specific unit: the organization and training of the professionals involved, establishment of the patient selection criteria, and design of the patients' training course, follow-up strategy and equipment. In addition, the results of the study conducted in our Unit, showing a high degree of patient satisfaction, are included. At this moment 20% of our patients are included in the self-control strategy.
