Sarcopenia and Nutrition in Elderly Rheumatoid Arthritis Patients: A Cross-Sectional Study to Determine Prevalence and Risk Factors.

OBJECTIVE: To describe the prevalence of sarcopenia in rheumatoid arthritis (RA) patients aged ≥65 years and identify the risk factors associated with sarcopenia. METHODS: This is a multicenter, controlled, cross-sectional study of 76 RA patients and 76 age- and sex-matched healthy controls. Sarcopenia was defined according to the revised criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Whole-body dual-energy X-ray absorptiometry (DXA) was performed. Binary regression was used to assess the relationship between sarcopenia and sex, age, duration of RA, Mini Nutritional Assessment (MNA) score, and Short Physical Performance Battery (SPPB) score in patients with RA. RESULTS: Nearly 80% of participants were female, and the average age was >70 years. Patients with RA had lower muscle mass and greater adiposity (fat-to-muscle ratio mean [SD] 0.9 [0.2] vs. 0.8 [0.2]; p = 0.017) than controls, mainly in the central area (android/gynoid ratio, median [p25-p75]: 1.0 [0.9-1.2] vs. 0.9 [0.8-1.1]; p < 0.001). Twelve patients (15.8%) and three controls (3.9%) had confirmed sarcopenia (p = 0.014). Sarcopenic obesity was observed in 8/76 patients with RA (10.5%) and in 1/76 controls (1.3%) (p = 0.016). The factors associated with sarcopenia were male sex (OR [95% CI]: 9.3 [1.1-80.4]; p = 0.042), disease duration (OR [95% CI]: 1.1 [1.0-1.2]; p = 0.012), and nutritional status according to the MNA (OR [95% CI]: 0.7 [0.5-0.9]; p = 0.042). CONCLUSIONS: Our results suggest that patients with RA aged ≥65 years may be at increased risk for sarcopenia, adiposity, and malnutrition (especially male patients with long-standing disease) and have poor nutritional status.

[Influence of learning styles of nursing students on teaching strategies choice]. / Elección de estrategias de enseñanza. Influencia de los estilos de aprendizaje del alumnado de enfermería.

The objective of this research focuses on the framework of teaching strategies, by acknowledging learning styles as first determination and, in relation to the changes that these are going through, identifying the teaching strategies best rated and preferred by the students. This is a prospective open cohort study with the students of Nursing Diploma 2007/2010 of the Universidad de Córdoba. Once the population was identified in the first year (first analysis), annual measurings were undertaken every year during their training. In order to study the learning styles, the questionnaire CHAEA was administered and a scale from 1 to 10 (1 = highest, 10 = lowest) was used to determine the preferences for learning strategies. The results show the variability of the learner (up to 11 styles). However, the dominant style is the reflective, followed by the theoretical and the pragmatic. The least developed was the active style. As the years of training go by, a tendency towards a dual style (reflective-theoretical) can be observed. In relation to teaching strategies, the preferred ones were those set in professional areas, workshops and debates. Relevant changes were also seen as they advanced in their training. The results establish a specific significant relationship between learning styles and teaching strategies.
