Italian healthcare professionals' attitude and barriers to mandatory reporting of elder abuse: An exploratory study.

INTRODUCTION: Elder abuse in recent times has reached a remarkable international importance. This complex phenomenon is still little understood and studied in Italy. The aim of this study was to explore Italian healthcare professionals' attitude and barriers toward elder abuse, with a glimpse on the current scenario and evidences to develop an action plan. MATERIALS AND METHODS: 42 healthcare professionals filled a questionnaire with 13 open-ended questions, analyzed with a qualitative content analysis. Data were grouped under the following 4 core-themes: description of elder abuse, abuse detection and perception, barriers to reporting, and professional orientation and approach; then they were analyzed to find their central component and discussed jointly. RESULTS: The respondents described physical (64%) and psychological (50%) abuse and neglect (50%) as the three main characteristics of elder abuse; the 59% of them reported at least one experience in detecting or suspecting elder abuse. The 76% of participants believed the report has to be submitted to the Judicial Authority only in presence of compelling evidences. Furthermore, the 73% of the sample perceived that healthcare professionals are the main figures who have to cope with elder abuse, however they did not feel as their exclusive role the assessment of the patients' potential abuse. CONCLUSION: Knowledge about elder abuse was limited to physical/psychological issues and, moreover, the legal obligation to report was only poorly known. Imperative is the creation of specific education and training courses, in addition to the need for a multidisciplinary and empathetic approach.

In vitro exposure of human lymphocytes to 900 MHz CW and GSM modulated radiofrequency: studies of proliferation, apoptosis and mitochondrial membrane potential.

The aim of this study was to investigate the nonthermal effects of radiofrequency (RF) fields on human immune cells exposed to a Global System for Mobile Communication (GSM) signal generated by a commercial cellular phone and by a sinusoidal non-modulated signal. To assess whether mobile phone RF-field exposure affects human immune cell functions, peripheral blood mononuclear cells (PBMCs) from healthy donors were exposed in vitro to a 900 MHz GSM or continuous-wave (CW) RF field 1 h/day for 3 days in a transverse electromagnetic mode (TEM) cell system (70-76 mW/kg average specific absorption rate, SAR). The cells were cultured for 48 or 72 h, and the following end points were studied: (1) mitogen-induced proliferation; (2) cell cycle progression; (3) spontaneous and 2-deoxy-D-ribose (dRib)-induced apoptosis; (4) mitochondrial membrane potential modifications during spontaneous and dRib-induced-apoptosis. Data obtained from cells exposed to a GSM-modulated RF field showed a slight decrease in cell proliferation when PBMCs were stimulated with the lowest mitogen concentration and a slight increase in the number of cells with altered distribution of phosphatidylserine across the membrane. On the other hand, cell cycle phases, mitochondrial membrane potential and susceptibility to apoptosis were found to be unaffected by the RF field. When cells were exposed to a CW RF field, no significant modifications were observed in comparison with sham-exposed cells for all the end points investigated.

Age-dependent changes in the susceptibility to apoptosis of peripheral blood CD4+ and CD8+ T lymphocytes with virgin or memory phenotype.

Susceptibility to apoptosis changes with age and most of the available data on lymphocytes refer to mitogen stimulated cells. We studied this susceptibility in quiescent, purified CD4+ or CD8+ T cells from a group of Italian old people compared with a group of young people. We found that an apoptotic agent such as 2-deoxy-D-ribose (dRib), which acts via glutathione depletion and oxidative stress, was more effective in CD4+ T cells from young donors, while no difference was found in CD8+ T cells. On the contrary, another agent such as TNF-alpha, which acts via receptor engagement, was more effective in CD8+ T cells from old subjects, and no difference was found in CD4+ T cells. When marker of activation-memory were investigated, no difference between young and old subjects was found when dRib was used. Differently, when TNF-alpha was used, memory and activated CD4+ T cells from old donors were less sensitive than younger counterparts, while memory CD8+ T cells from old donors were more sensitive than younger counterparts. This suggests that age-related changes in susceptibility to apoptosis of resting T cells largely depend on the type of the apoptotic stimulus which is used as well as on the memory phenotype of the cells. These results may also account, at least in part, for the deep remodelling of T cell repertoire that occurs during ageing.
