    Elder abuse among Spanish and Iranian people: new methodological approach to the same old story
    (Springer, 2021-03-30) Maurandi-López, Antonio; Perez-Carceles, M.D.; Didáctica de las Ciencias Matemáticas y Sociales
    Elder abuse continues to be a taboo, mostly underestimated, ignored by societies across the world. Recent systematic reviews and meta-analyses have revealed significant variations in the prevalence of elder abuse, with large geographic variations. This is the first study that compares the prevalence of elder abuse and risk factors between a European and Asian countries and using the same method. Cross-sectional surveys were conducted in Spain and Iran. Eight hundred forty subjects, aged 65 and over, were chosen randomly from patients in primary care health centres. Prevalence of abuse and subtypes and risk factors were obtained using structured interviews. To minimize the potential effects of selection bias, a propensity score matching was performed. Multiple correspondence analysis was used to evaluate the possible relationships among all the variables and to identify specific profiles. Five hundred thirty-two older people remained for the analysis after matching. The prevalence of abuse was 39.1% in Spain and 80.5% in Iran. Elder abuse and its subtypes are significantly more probable in Iran than in Spain. Out of every five elderly people questioned, two in Spain and four in Iran responded affirmatively to a question concerning elder abuse. Multiple correspondence analysis allows the differences between patterns of elder abuse between both populations to be visualized. Elder abuse is a prevalent problem in Spain and Iran. While some characteristics are shared in the pattern of abuse there are different profiles between the two countries. Detecting elder abuse should be a priority objective in clinical and forensic setting.

    Trace elements in forensic human lung: a new approach to the diagnosis of seawater drowning. A preliminary study

    The diagnosing of drowning remains one of the most challenging activities for the forensic pathologist. There is little information on the impact on the lung as a target organ in death by drowning. We aimed to investigate the concentration of trace elements in the lungs of people who had suffered different types of death to evaluate the discriminating ability of trace elements to identify seawater drowning (SWD). A total of 11 trace elements were analyzed by Inductively Coupled Plasma-Mass Spectrometry in 74 forensic cases. Sampler scanning electron microscopy and Energy Dispersive X-ray spectroscopy (EDX) were used to identify ultrastructural lung alterations. A Principal Component Analysis (PCA) of trace elements was carried out. The trace elements in SWD lungs were detected in the following order of concentration: Br˃Zn˃Sr˃Cr˃Cu˃As˃Pb˃Se˃Mn˃Ni˃Cd. Our results showed significantly higher concentrations of Br and Sr (P = 0.010 and P = 0.000) and significantly lower concentrations of Zn, Pb, Cu, Cd, and Se in SWD compared with other causes of death. After adjusting by confounder factors, Sr and Br remained as predictive independent factors for diagnosis of drowning (p = 0.042, in both cases). These results were confirmed by PCA, which revealed a wide separation between SWD and the rest of the causes of death. Our SWD cohort was characterized by high concentrations of the trace elements Br and Sr and low concentrations of Zn, Pb, Cu, Cd, and Se in lung tissue, while PCA showed its discriminatory capacity to identify death by seawater drowning. These findings, together with those obtained using other techniques, can be of great importance in the diagnosis of SWD.
