Background Hip fractures (HF) are a high-impact geriatric syndrome. Vitamin B12 deficiency is an HF risk factor. There are few studies on prevalence of B12 deficiency in older adults with HF. The objectives are as follows: in older adults with HF, to describe/characterize plasma levels of vitamin B12 (PL-B12); to verify presence/absence of a subgroup with borderline, near-deficient PLB12; to describe HF incidence; and to analyse relationships between PL-B12 and studied variables.

Introduction Within the occupational field, changes in the characteristics of work have revealed risks associated with static, repetitive work and litle physical activity, which together with individual health conditions of workers can trigger diseases and musculoskeletal disorders. Objectives To obtain a preliminary characterization of workers in an industrial area, including their health and working conditions. Methods This is a cross-sectional study with a quantitative approach, developed with 69 men who worked in the industrial area of Viña del Mar, Chile. A clinical and occupational evaluation was carried out with the application of the International Physical Activity Questionnaire as well as the Standardized Nordic Questionnaire. Results The following risk factors were identified: 53.6% of the workers were smokers, 92.8% presented low levels of physical activity, and 70.3% reported feeling pain in body segments that were physically required during their work tasks. Among all workers, 63% were overweight according to their body mass index and 62% presented high systolic pressure. Pain was mostly detected in the spine, and it was slightly associated with forklif operation by older workers (t-test p < 0.05). Conclusions Workers were in the presence of cardiovascular and occupational risks. It is necessary to promote timely education and training on health conditions and to evaluate risks associated with machinery operation in order to prevent work-related pain.

Introducción. se ha descrito que una favorable percepción de los estudiantes sobre un proceso de enseñanza y aprendizaje constituye un aspecto relevante que favorece el desempeño académico. sin embargo, existe escasa información sobre otros factores de riesgo académico de los estudiantes que ingresan en la educación superior. Objetivo. Conocer la experiencia académica previa de los estudiantes de cinesiología, su percepción sobre las metodologías de enseñanza y su relación con el rendimiento. Sujetos y métodos. Estudio descriptivo de corte transversal, en el cual se estudiaron 108 alumnos de la Escuela de Cinesiología de la asignatura 'Anatomía del aparato locomotor'. se diseñó y validó un cuestionario para evaluar la percepción de satisfacción y la experiencia académica previa. Posteriormente se aplicó a los estudiantes y se registraron sus calificaciones durante el semestre. Resultados. los estudiantes evaluaron positivamente la gestión docente en metodología y enseñanza en sus tres dimensiones, obteniendo una puntuación de 3,5 ± 0,3. sin embargo, el 65,7% de los estudiantes reprobó la asignatura. los resultados indican que no hay una relación directa entre la metodología de enseñanza y el rendimiento académico. no obstante, la experiencia académica previa parece ser de gran importancia. Conclusión. Es necesario debatir sobre variables de índole académica, como la experiencia previa de los estudiantes, que constituyen factores de predicción del éxito académico y también aquellas que favorecen el burnout académico, e incorporar estrategias de apoyo a estudiantes que presentan estas características para un mejor desempeño académico. Palabras clave. Educación médica. Experiencia académica. Percepción estudiantil. rendimiento académico.
