ABSTRACT
Introducción: Las fracturas por fragilidad (FF) son frecuentes en pacientes osteoporóticos. Existen una serie de factores de riesgo y variables clínicas, que podrían predecir su aparición. Material y método: Se realizó un estudio observacional retrospectivo de casos y controles. Los casos estuvieron definidos por la presencia de una FF (326 participantes) y los controles por pacientes de similares características sin FF (629 participantes). Resultados: Ciertos factores aumentan el riesgo de FF, como un diagnóstico previo de DM tipo 2 (OR: 2,001), las elevaciones de 1ng/mL del CTX (OR: 1,88), tener antecedentes parentales de fractura de cadera (OR: 1,667), el aumento en 5 años en la edad (OR: 1,39) y los incrementos de 1kg/m2 del IMC (OR: 1,041). Por el contrario, otros factores evaluados disminuyen ese riesgo, como mantener unos niveles de 25(OH)D≥30ng/mL (OR: 0,686) y una T-score≥−2,5 (OR: 0,642). Conclusiones: Niveles de 25(OH)D≥30ng/mL y una T-score en el cuello femoral≥−2,5 son factores protectores de las FF, mientras que el diagnóstico previo de DM tipo 2, un CTX elevado, el antecedente parental de fractura de cadera, un incremento de 1kg/m2 del IMC y el aumento de la edad en 5 años serían predisponentes a padecer FF.(AU)
Introduction: Fragility fractures (FF) are frequent in osteoporotic patients. There are a series of risk factors and clinical variables that could predict their appearance. Material and method: A retrospective observational study of cases and controls was carried out. Cases were defined by the presence of FF (326 participants) and controls by patients with similar characteristics without FF (629 participants). Results: Certain factors increase the risk of FF, such as a previous diagnosis of type 2 DM (OR: 2.001), 1ng/mL elevations of CTX (OR: 1.88), having a parental history of hip fracture (OR: 1.667), 5-year increase in age (OR: 1.39), and 1kg/m2 increases in BMI (OR: 1.041). In contrast, other factors evaluated decreased this risk, such as maintaining 25(OH)D levels≥30ng/mL (OR: 0.686) and a T-score≥−2.5 (OR: 0.642). Conclusions: Levels of 25(OH)D≥30ng/mL and a T-score at the femoral neck≥−2.5 are protective factors for FF, while a previous diagnosis of type 2 DM, an elevated CTX, a parental history of hip fracture, an increase of 1kg/m2 in BMI and an increase in age by 5 years would be predisposing to FF.(AU)

A new method for the determination of clenbuterol by reversed-phase HPLC with UV detection has been developed. Clenbuterol was eluted on a C8 column (250 x 4.6 mm I.D), using an isocratic eluent consisting of an acetonitrile -0.02 M phosphate buffer (25:75, v/v) adjusted to pH 2.8 with phosphoric acid. The method was linear from 2.5 to 50 ng injected. The detection limit was established to be 0.5 ng (signal/background ratio: 3), and the quantification limit was 2.5 ng. With the proposed method, we got a simple and rapid detection of clenbuterol in the retina, part of the animal where the biggest amount of clenbuterol is accumulated and where it remains for the longest time after any treatment.
