RESUMO
Objetivo Evaluar la asociación entre el cociente de los dedos segundo y cuarto (2D:4D), como un biomarcador de la exposición prenatal a andrógenos, y la presencia de cáncer de próstata (CaP). Métodos Estudio de casos y controles con 260 hombres que consultaron en el Servicio de Urología del Hospital General Universitario Reina Sofía (Murcia, España). Los casos (n = 125) fueron pacientes diagnosticados de CaP por anatomía patológica a los que se les realizó una prostatectomía radical. Los controles (n = 135) fueron pacientes que consultaron en Urología por otro motivo y que no mostraron signos ni síntomas de patología prostática. La longitud del 2D y 4D de la mano derecha fue medida mediante un pie de rey digital y se calculó el cociente entre ambos (2D:4D). Para los análisis estadísticos se utilizaron modelos de regresión logística obteniendo Odds ratios (OR) crudas y ajustadas e intervalos de confianza al 95%. Resultados Los casos presentaron un cociente 2D:4D significativamente menor que los controles. El cociente 2D:4D se relacionó significativamente con la presencia de CaP. Tras el ajuste multivariante, se observó que los varones que se encontraban en el primer tercil de distribución del cociente 2D:4D, presentaban casi el doble de riesgo de padecer CaP (OR 1,9: IC 95% 1,14,0; P-valor = 0,040) en comparación con los varones que se encontraban en el segundo y tercer tercil. Conclusiones Una mayor exposición prenatal a andrógenos, reflejada por un cociente 2D:4D menor, podría estar asociado con riesgo aumentado de padecer CaP, pero más estudios son necesarios para corroborar esos hallazgos.
Objective To evaluate the association between second to fourth digit (2D:4D) ratio, as a biomarker of prenatal androgen exposure, and the presence of prostate cancer (PCa). Methods This was a case-control study of 260 men attending a Department of Urology in a Murcia Region hospital (Spain). Cases (n = 125) were patients who underwent radical prostatectomy due to PCa and were diagnosed by specimen's histopathology. Controls (n = 135) were patients who showed no signs or symptoms of prostate disease. The length of 2D and 4D of the right hand was measured two times using a digital caliper, and the ratio calculated (2D:4D). Unconditional multiple logistic regressions [crude and adjusted Odds ratios (OR) and 95% confidence intervals (CI)] were performed to evaluate associations between the 2D:4D ratio and presence of PCa. Results Cases showed significantly lower 2D:4D ratios than controls. 2D:4D ratios were significantly associated with the presence of PCa. After controlling for important covariates, men in the first tertile of the 2D:4D ratio distribution, compared with the second and third tertile, were almost two-times [OR 1.9 (95% CI 1.14.0; P-value = 0.040] more likely to have PCa. Conclusions A higher prenatal androgen exposure, indicated by lower 2D:4D ratios, might be associated with higher PCa risk, but further research is needed to confirm these findings in other male populations.

Immigrants are vulnerable to Intimate partner violence (IPV). This study aims at characterising IPV among Colombian immigrants, and to identify its associated factors. Cross-sectional study on 336 Colombian immigrants (46 % women), aged 15-70 years, living in Spain. Self-reported questionnaire information on IPV suffered throughout the last year was collected face-to-face. Multivariable logistic regression was used to identify factors associated with IPV. Almost 30 % of participants reported IPV, without differences by gender (p = 0.339). Partner's alcohol consumption was associated with a higher frequency of being victim of IPV in both sexes. In women, low educational level, and discrimination were further associated to IPV. Younger age, and poorer self-perceived health in Spain as compared to Colombia were factors associated in men. Results showed similarly high levels of IPV among immigrant men and women. Alcohol consumption, education, discrimination, age, and poor self-perceived health were factors associated to IPV.
