Incidence of Suicide in East Azerbaijan Province, Iran

AbstractBackground:Suicide is a major problem world-wide. The aim of this study was to determine the incidence of suicide in East Azerbaijan province, Iran. Methods: A cross-sectional study conducted from 2010 to 2011. We analysed some characteristics of the cases of suicide based on the health system database. Variables such as demographics, outcomes (fatal/nonfatal), and methods used were recorded. Data were analysed using Chi-square as well as T-test.Results: A total of 3,768 reported cases of suicide were analysed. More cases were reported by married than single people. The incidence rate of suicide was 101.3 per 100,000. Most of the attempted suicides occurred in younger people. Attempted suicide in women (63.7%) was higher than men (36.3%). The most frequent method of suicide in both sexes was drug overdose. There was a statistically significant relationship between suicide’s outcome and gender, job, marital status and education (p<0.001). The case fatality rate among males was significantly higher than females (OR=3.7, 95% CI: 2.5–5.8). Hanging (72.3%) and drug overdose (0.9%) had the highest and lowest case fatality rate, respectively. Drug overdose was slightly more frequent among women than men (91.3% versus 84.2%). The rate of poisoning increased gradually until the age-group 45-54 years. Drug overdose was more prevalent among single than married people.Conclusions: Due to the high incidence of completed suicide, it is recommended to establish counselling centres for mental ill-health, especially a suicide hotline with appropriate availability to all population

Highly-parallelized simulation of a pixelated LArTPC on a GPU

The rapid development of general-purpose computing on graphics processing units (GPGPU) is allowing the implementation of highly-parallelized Monte Carlo simulation chains for particle physics experiments. This technique is particularly suitable for the simulation of a pixelated charge readout for time projection chambers, given the large number of channels that this technology employs. Here we present the first implementation of a full microphysical simulator of a liquid argon time projection chamber (LArTPC) equipped with light readout and pixelated charge readout, developed for the DUNE Near Detector. The software is implemented with an end-to-end set of GPU-optimized algorithms. The algorithms have been written in Python and translated into CUDA kernels using Numba, a just-in-time compiler for a subset of Python and NumPy instructions. The GPU implementation achieves a speed up of four orders of magnitude compared with the equivalent CPU version. The simulation of the current induced on 10^3 pixels takes around 1 ms on the GPU, compared with approximately 10 s on the CPU. The results of the simulation are compared against data from a pixel-readout LArTPC prototype

The DUNE far detector vertical drift technology. Technical design report

DUNE is an international experiment dedicated to addressing some of the questions at the forefront of particle physics and astrophysics, including the mystifying preponderance of matter over antimatter in the early universe. The dual-site experiment will employ an intense neutrino beam focused on a near and a far detector as it aims to determine the neutrino mass hierarchy and to make high-precision measurements of the PMNS matrix parameters, including the CP-violating phase. It will also stand ready to observe supernova neutrino bursts, and seeks to observe nucleon decay as a signature of a grand unified theory underlying the standard model. The DUNE far detector implements liquid argon time-projection chamber (LArTPC) technology, and combines the many tens-of-kiloton fiducial mass necessary for rare event searches with the sub-centimeter spatial resolution required to image those events with high precision. The addition of a photon detection system enhances physics capabilities for all DUNE physics drivers and opens prospects for further physics explorations. Given its size, the far detector will be implemented as a set of modules, with LArTPC designs that differ from one another as newer technologies arise. In the vertical drift LArTPC design, a horizontal cathode bisects the detector, creating two stacked drift volumes in which ionization charges drift towards anodes at either the top or bottom. The anodes are composed of perforated PCB layers with conductive strips, enabling reconstruction in 3D. Light-trap-style photon detection modules are placed both on the cryostat's side walls and on the central cathode where they are optically powered. This Technical Design Report describes in detail the technical implementations of each subsystem of this LArTPC that, together with the other far detector modules and the near detector, will enable DUNE to achieve its physics goals

The relationship between the chronicity and severity of abuse, socio-economics, psychosocial factors and mental health

The abuse and mental health of older persons are sources of great concern. However, there are limited data on the relation between the chronicity (frequency of abuse) by severity (minor, severe) of abuse (e.g. psychological, physical) and mental health (e.g. depression). Women/men aged 60–84 years from seven European cities (n=4,467) participated in this study, and data were analysed with bivariate/multivariate methods. High chronicity (frequency, median/above) of psychological and physical abuse independently of severity was related to depression and anxiety; financial and overall abuse to anxiety; and minor financial abuse and overall abuse to depression. Regressions showed that some factors (e.g. being from Greece) were associated with a lower depression/anxiety “risk” and others (e.g. low social support) with high risk. Low chronicity (frequency, below median) of psychological abuse was associated with a lower anxiety risk. The management of depression/anxiety, particularly anxiety, among elders should also consider the roles of abuse and social support

Lifetime Abuse and Quality of Life among Older People

Few studies have evaluated the impact of lifetime abuse on quality of life (QoL) among older adults. By using a multinational study authors aimed to assess the subjective perception of QoL among people who have reported abuse during the course of their lifetime. The respondents (N = 4,467; 2,559 women) were between the ages of 60 and 84 years and living in seven European countries (Germany, Greece, Italy, Lithuania, Portugal, Spain, and Sweden). Lifetime abuse was assessed by using a structured questionnaire that allowed to assess lifetime experiences of abuse. QoL was assessed with the World Health Organization Quality of Life–Old module. After adjustment for potential confounders, authors found that to have had any abusive experience decreased the score of sensory abilities. Psychological abuse was associated with lower autonomy and past, present, and future activities. Physical abuse with injuries significantly decreased social participation. Intimacy was also negatively associated with psychological abuse, physical abuse with injury, and sexual abuse. The results of this study provide evidence that older people exposed to abuse during their lifetime have a significant reduction in QoL, with several QoL domains being negatively affected.ABUE

The prevalence, severity and chronicity of abuse towards older men : Insights from amultinational European survey

Background Elder abuse is a growing public health question among policy makers and practitioners in many countries. Research findings usually indicate women as victims, whereas male elder abuse still remains under-detected and under-reported. We aimed to investigate the prevalence, severity and chronicity of abuse (psychological, physical, physical injury, sexual, and financial) against older men, and to scrutinize factors (e.g. demographics) associated with high chronicity of any abuse. Methods Randomly selected older men (n = 1908) aged 60–84 years from seven European cities (Ancona, Athens, Granada, Kaunas, Stuttgart, Porto, Stockholm) were interviewed in 2009 via a cross-sectional study concerning abuse exposure during the past 12 months. Results Findings suggested that prevalence of abuse towards older men varied between 0.3% (sexual) and 20.3% (psychological), with severe acts between 0.2% (sexual) and 8.2% (psychological). On the whole, higher chronicity values were for injury, followed by psychological, financial, physical, and sexual abuse. Being from Sweden, experiencing anxiety and having a spouse/cohabitant/woman as perpetrator were associated with a greater “risk” for high chronicity of any abuse. For men, severity and chronicity of abuse were in some cases relatively high. Conclusions Abuse towards older men, in the light of severe and repeated acts occurring, should be a source of concern for family, caring staff, social work practice and policy makers, in order to develop together adequate prevention and treatment strategies.ABUE
