Relationship between the FRAX index and physical and cognitive functioning in older people.

OBJECTIVE: To assess the relationship between the FRAX index and the Barthel index/MiniMental State Examination in older people. PATIENTS AND METHODS: Observational descriptive study. Demographic data, comorbidity, dependency and cognitive state, and risk of osteoporotic fracture were collected. RESULTS: A total of 375 patients were included (60% female) Patients with a low-risk FRAX for hip fractures had a higher Mini-mental (25, 95% CI = 24-27 vs. 22, 95% = 21 to 23, p = .0001), a higher Barthel index (88, 95% CI = 84-93 vs 72, 69 to 76, p = .0001) without differences in the Charlson index. Bivariate analysis showed an inverse association between FRAX and scales but logistic regression showed only female sex (OR 4.4, 95% CI = 2.6-7.6) and the non-dependent Barthel index (OR = 0.104, 95% CI = 0.014-0.792) remained significant and. Barthel index/Mini-mental constructed a significant model capable of predicting a risk of hip fracture of >3% measured by the FRAX index, with an area under the curve of 0.76 (95% CI = 0.7-0.81). CONCLUSIONS: The FRAX index is related to other markers of geriatric assessment and the association between these variables can predict a risk of hip fracture of >3% measured by the FRAX index. Key messages Geriatric assessment indexes may be as important as the FRAX index, which is based on clinical risk factors, in predicting the fracture risk in older patient.

Retrieval of fractured files based on electrochemical dissolution / Retiro de limas fracturadas basado en la disolución electroquímica

The purpose of this study was to investigate whether the Electrochemical Dissolution (DE) facilitates the retrieval of fractured files, from Endo-Training block with an artificial root canal, by using ultrasonic techniques (US). Twenty Endo-Training block with an artificial single canal with working length 16 mm and twenty nickel-titanium (NiTi) Protaper Universal rotary files were used. 10 Shaping S1 files and 10 Shaping S2 files, were sectioned transversally within the conduit, to 5mm of the apical tip. Twenty samples were divided into four groups: Group1 and 3 received the action of DE and US, and groups 2 and 4 received the action of US. To remove the fragments we used Staging Platform and Dental Microscope. Outcome was analyzed statistically by Student t test. Statistical Analysis showed a significant difference in retrieval time of the fragments and weight loss mass of Endo training block ultrasonic tips were used, between groups that applied Ultrasonic with electrochemical dissolution and the group using only ultrasonic. It can be concluded that there was weight loss mass of separated fragment by electrochemical action, however, it was not sufficient and its use alone was inconclusive to retrieve the fragments. The procedure needs to be complemented with the use of the staging platform, ultrasonic tips and Dental Microscope.

Este estudio tiene como propósito determinar si la Disolución Electroquímica (DE) favorece el retiro de fragmentos de limas fracturadas, insertos en bloc endodónticos de entrenamiento de resina, con un conducto radicular simulado, mediante el uso de ultrasonido (US). Se utilizaron 20 bloc y 20 limas rotatorias usadas ProTaper Universal de NiTi Shaping Files, 10 S1, 10 S2, que fueron fracturadas dentro del conducto, a 5 mm desde la punta apical y divididos en Grupo1 y 3 que recibieron la acción de la DE y US; y Grupo 2 y 4 sólo utilizó US. Para retirar los fragmentos se utilizó Plataforma de Trabajo y Microscopio Dental. Los datos fueron analizados con la prueba T de Student. Los resultados indican que existen diferencias estadísticamente significativas en el tiempo de retiro de los fragmentos y en la pérdida de masa del bloc de entrenamiento por el uso del ultrasonido, en los grupos que se aplicó Disolución Electroquímica más Ultrasonido. Se puede concluir que la acción electroquímica permite que exista pérdida de masa del fragmento fracturado, sin embargo, no es suficiente y su sola utilización no es concluyente para retirar los fragmentos, es necesario complementar el procedimiento con la utilización de la Plataforma de Trabajo, puntas de ultrasonido y el Microscopio Dental.
