The EHRI Online Portal allows you to explore information about Holocaust-related institutions and their collections across Europe and beyond. It is one of the main achievements of the European Holocaust Research Infrastructure (EHRI) project, and it seeks to overcome one of the hallmark challenges of Holocaust research: the fragmentation and wide geographic dispersal of archival sources documenting the event.

This video gives a short introduction to the what, why and how of the online portal of the European Holocaust Research Infrastructure, in just under 3 minutes. www.ehri-project.eu

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric syndrome with complex etiology. Studies aiming to explore genetic susceptibility and environmental triggers of PTSD have been increasing. However, the results are limited and highly heterogeneous. To understand the genetic study status of PTSD and explore more reliable candidates, we obtained 105 PTSD related genetic studies by comprehensively literature searching and filtering 1762 studies. Detailed phenotype and sample information for each study and association results for each genetic marker were extracted.

Use of ED medication can be seen as a marker for ED. ED is associated with increasing age, exposure to traumatic events and physical injuries in military veterans. The objective of this study was to assess the prevalence of use of ED medication in Dutch military personnel in the period 2003–2012 and to assess its association with age and psychotropic medication use. Data on dispensing of ED medication, age and co-medication with psychotropic medication of all Dutch military personnel between 2003 and 2012 were collected.
