Previous research has documented significant variation in the prevalence of posttraumatic stress disorder (PTSD) depending on type traumatic experience (TE) and history TE exposure, but relatively small sample sizes these studies resulted a number unresolved basic questions.To examine disaggregated associations with PTSD large cross-national community epidemiologic data set.The World Health Organization Mental surveys assessed 29 types (lifetime age at first exposure) DSM-IV that was...

The U.S. Environmental Protection Agency (EPA) presently uses a 40 ppbv background O 3 level as baseline in its risk assessments. This is defined those concentrations that would exist the absence of North American emissions. Lefohn et al. [2001] have argued frequent occurrences above 50–60 at remote northern sites spring are stratospheric origin, challenging EPA estimate and implying current standard (84 ppbv, 8‐hour average) may be unattainable. We show 3‐D global model tropospheric...

BackgroundAlthough childhood adversities are known to predict increased risk of post-traumatic stress disorder (PTSD) after traumatic experiences, it is unclear whether this association varies by adversity or experience types age.AimsTo examine variation in associations with PTSD according types, and life-course stage.MethodEpidemiological data were analysed from the World Mental Health Surveys (n = 27 017).ResultsFour (physical sexual abuse, neglect, parent psychopathology) associated...

The months after psychiatric hospital discharge are a time of high risk for suicide. Intensive postdischarge case management, although potentially effective in suicide prevention, is likely to be cost-effective only if targeted at high-risk patients. A previously developed machine learning (ML) model showed that suicides can predicted from electronic health records and geospatial data, but it unknown prediction could improved by adding additional information. To determine whether information...

There is a very high suicide rate in the year after psychiatric hospital discharge. Intensive postdischarge case management programs can address this problem but are not cost-effective for all patients. This issue be addressed by developing risk model to predict which inpatients might need such program. We developed 391,018 short-term admissions of US veterans Veterans Health Administration (VHA) hospitals 2010-2013. Records were linked with National Death Index determine within 12 months...

The Department of Veterans Affairs recently began requiring annual suicide ideation (SI) screening all patients and additional structured questions for reporting SI. Related changes are under consideration at the Defense. These will presumably lead to higher SI detection, which require hiring clinical staff and/or developing a decision support system focus in-depth risk assessments on considered high risk.To carry out proof-of-concept study whether brief question battery from survey US Army...
