  abstract  = {Objectives Posttraumatic stress disorder (PTSD) is triggered by extremely stressful environmental events and characterized by high emotional distress, re-experiencing of trauma, avoidance and hypervigilance. The present study uses polygenic risk scores (PRS) derived from the UK Biobank (UKBB) mega-cohort analysis as part of the PGC PTSD GWAS effort to determine the heritable basis of PTSD in the South Eastern Europe (SEE)-PTSD cohort. We further analyzed the relation between PRS and additional disease-related variables, such as number and intensity of life events, coping, sex and age at war on PTSD and CAPS as outcome variables. Methods Association of PRS, number and intensity of life events, coping, sex and age on PTSD were calculated using logistic regression in a total of 321 subjects with current and remitted PTSD and 337 controls previously subjected to traumatic events but not having PTSD. In addition, PRS and other disease-related variables were tested for association with PTSD symptom severity, measured by the Clinician Administrated PTSD Scale (CAPS) by liner regression. To assess the relationship between the main outcomes PTSD diagnosis and symptom severity, each of the examined variables was adjusted for all other PTSD related variables. Results The categorical analysis showed significant polygenic risk in patients with remitted PTSD and the total sample, whereas no effects were found on symptom severity. Intensity of life events as well as the individual coping style were significantly associated with PTSD diagnosis in both current and remitted cases. The dimensional analyses showed as association of war-related frequency of trauma with symptom severity, whereas the intensity of trauma yielded significant results independently of trauma timing in current PTSD. Conclusions The present PRS application in the SEE-PTSD cohort confirms modest but significant polygenic risk for PTSD diagnosis. Environmental factors, mainly the intensity of traumatic life events and negative coping strategies, yielded associations with PTSD both categorically and dimensionally with more significant p-values. This suggests that, at least in the present cohort of war-related trauma, the association of environmental factors and current individual coping strategies with PTSD psychopathology was stronger than the polygenic risk.},

  abstract  = {During deployment, soldiers face situations in which they are not only exposed to violence but also have to perpetrate it themselves. This study investigates the role of soldiers' levels of posttraumatic stress disorder (PTSD) symptoms and appetitive aggression, that is, a lust for violence, for their engaging in violence during deployment. Furthermore, factors during deployment influencing the level of PTSD symptoms and appetitive aggression after deployment were examined for a better comprehension of the maintenance of violence. Semi-structured interviews were conducted with 468 Burundian soldiers before and after a 1-year deployment to Somalia. To predict violent acts during deployment (perideployment) as well as appetitive aggression and PTSD symptom severity after deployment (postdeployment), structural equation modeling was utilized. Results showed that the number of violent acts perideployment was predicted by the level of appetitive aggression and by the severity of PTSD hyperarousal symptoms predeployment. In addition to its association with the predeployment level, appetitive aggression postdeployment was predicted by violent acts and trauma exposure perideployment as well as positively associated with unit support. PTSD symptom severity postdeployment was predicted by the severity of PTSD avoidance symptoms predeployment and trauma exposure perideployment, and negatively associated with unit support. This prospective study reveals the importance of appetitive aggression and PTSD hyperarousal symptoms for the engagement in violent acts during deployment, while simultaneously demonstrating how these phenomena may develop in mutually reinforcing cycles in a war setting.},

  abstract  = {Diese Arbeit ist Teil einer prospektiv geplanten, nicht interventionellen Querschnittsstudie, in welcher psychische Belastungen nach allogener Stammzelltransplantation untersucht wurden. Hierf{\"u}r wurden von Juli bis August 2011 Daten von 50 Patienten der KMT Ambulanz der Universit{\"a}tsklinik W{\"u}rzburg erhoben. Die Studienteilnehmer wurden hinsichtlich Angst, Depression und Posttraumatischer Belastungsst{\"o}rung (PTBS) nach allogener Stammzelltransplantation befragt. Diese Dissertation besch{\"a}ftigte sich ausschließlich mit der Entwicklung einer PTBS nach allogener Transplantation. Zur Datenerhebung wurde die Posttraumatic Checklist Civilian Version (PCL-C) als etablierter und standardisierter Fragebogen verwendet. Neun Patienten gaben den Fragebogen nicht bzw. unvollst{\"a}ndig ab, wodurch sich eine endg{\"u}ltige Studienteilnehmerzahl von n=41 ergab. Das mittlere Alter betrug 53,4 Jahre (21-74 Jahre), 68\% waren m{\"a}nnlich und 85\% waren verheiratet. 22 Personen (54\%) litten an myeloischen Tumoren, 19 (46\%) litten an lymphatischen Tumoren. Die Mehrheit der Patienten erhielt periphere Blutstammzellen eines mit ihnen nicht verwandten Spenders (51\%). Zum Zeitpunkt der Datenerhebung lag die Transplantation im Schnitt 21,9 Monate zur{\"u}ck. Von den 41 untersuchten Patienten litten laut PCL-C sechs Personen (14,6\%) nach der Cut off Methode und f{\"u}nf Personen (12,2\%) nach der Cluster Methode an einer PTBS. Von einer partiellen PTBS waren zwei Patienten (4,9\%) betroffen. Das am h{\"a}ufigsten angegebene PTBS-Symptom war das Erleben von Intrusionen (41,5\%). Weder soziodemographische (Alter, Geschlecht, Familienstand) noch somatische Variablen (CMV Reaktivierung, akute oder chronische GvHD) zeigten eine signifikante Korrelation mit dem Auftreten einer PTBS. Ebenso konnte kein Zusammenhang zwischen der Zeit nach Transplantation und einer m{\"o}glichen psychischen Regeneration festgestellt werden. Von den sechs PTBS Patienten, die mittels PCL-C ermittelt werden konnten, wurden zwei gar nicht, drei mit Psychopharmaka und nur einer mit Psychopharmaka und Psychotherapie behandelt. Somit sind die Ergebnisse als Momentaufnahme zu verstehen, die einen Bedarf f{\"u}r eine optimierte Versorgung reflektiert. Dies unterstreicht auch die Notwendigkeit der Durchf{\"u}hrung weiterer, analytischer und gegebenenfalls auch interventioneller Studien in diesem Bereich, um einer PTBS vorzubeugen oder diese fr{\"u}hzeitig zu erkennen und entsprechend ad{\"a}quat zu behandeln.},
