Abstract
Most individuals diagnosed with borderline personality disorder (BPD) have been exposed to severe and traumatic stressors and thus frequently present with symptoms of a posttraumatic stress disorder (PTSD). Severe sleep disturbances often accompany these complex cases, but changes of sleep parameters during therapy and the impact of sleep on treatment response have barely been studied. Narrative Exposure Therapy (NET) is an evidence-based approach for the treatment of trauma-related psychological disorders. To investigate the effect of NET on sleep in patients with BPD and comorbid PTSD, we screened 45 inpatients and outpatients who met the inclusion criteria of both diagnoses according to DSM-IV and who had a minimum of 2 weeks' stable medication. Patients were allocated to NET (N = 13) or treatment as usual (TAU; N = 8) in blocks. Polysomnographies and psychological questionares were performed before, directly and 6 months after the last therapy session. The aim of this pilot study was to investigate the effectiveness of trauma therapy by NET on sleep quantity (total sleep time) and sleep continuity (sleep efficiency and awakenings) in patients with comorbid BPD and PTSD. Participants of the NET group compared with those who received TAU showed an increased reduction in sleep latency from baseline to the end of therapy and a reduction in arousals over time. Patients with longer pre-treatment total sleep time and pre-treatment REM sleep duration showed a better outcome of NET with respect to PTSD symptoms. NET seems not lead to a change in sleep for the worse during therapy and seems to improve sleep as good as treatment as usual. Furthermore, our results provide evidence of an influence of sleep structure at baseline on treatment success later on.

Abstract
BACKGROUND Prenatal stress and other prenatal risk factors (e.g. intimate partner violence) have a negative impact on mother's health, fetal development as well as enduring adverse effects on the neuro-cognitive, behavioral and physical health of the child. Mothers of low socio-economic status and especially those living in crime-ridden areas are even more exposed to a host of risk factors. Societies of extreme violence, poverty and inequalities, often present difficulties to provide adequate mental health care to the most needed populations. The KINDEX, a brief standardized instrument that assesses 11 different risk factors was used by midwives to identify pregnant women at-risk, in a suburban area with one of the highest levels of domestic violence in Lima. The instrument was designed to be used by medical staff to identify high-risk child-bearing women and, based on the results, to refer them to the adequate psychological or social support providers. The aim of this study is to assess the feasibility of psychosocial screening using the KINDEX in a Latin American Country for the first time, and to explore the relationship of the KINDEX with thee major risk areas, maternal psychopathology, perceived stress and traumatic experiences. METHODS The study was conducted in cooperation with the gynecological department of a general hospital in a suburban area of Lima. Nine midwives conducted interviews using the KINDEX of ninety-five pregnant women attending the gynecological unit of the hospital. From these, forty pregnant women were re-interviewed by a clinical psychologist using established instruments in order to assess the feasibility of the prenatal assessment in public health settings and the relationship of the KINDEX with maternal perceived stress, psychopathology symptoms and trauma load during pregnancy. RESULTS We found high rates of risk factors in the examined pregnant women comparable with those found in the general population. Significant correlations were found between the KINDEX sum score and the three risks areas, stress, psychopathology and trauma load as assessed in the Clinical Expert interviews. The different risks assessed by the KINDEX are related to higher levels of stress, psychopathology and trauma load, depending on the risk. CONCLUSIONS The relationship between past adverse experience and current stressors with perceived maternal stress, psychopathology symptoms and traumatic experiences confirm the importance of prenatal assessment for psychosocial risks. The use of KINDEX by midwives providing obstetrical care to pregnant women in urban Peru is feasible and can be used to identify high-risk women and refer them to the adequate mental health or social services for necessary attention and support. Early interventions are essential to mitigating the adverse effects of maternal stress, trauma and psychopathology on the fetus and child.

A study with unaccompanied refugee minors. Eur J Psychotraumatol 2016; 7:27856. [PMID: 26886483 PMCID: PMC4756624 DOI: 10.3402/ejpt.v7.27856] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2015] [Revised: 09/07/2015] [Accepted: 09/29/2015] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND There is strong support for familial abuse as a risk factor for later delinquency and violent offending, whereas empirical evidence about the contribution of experienced organized violence to the cycle of violence is less clear. Nevertheless not all abused children do become violent offenders. This raises the question of which factors influence these children's risk of future aggressive behavior. Recent evidence suggests that the trait of appetitive aggression plays an important role in the prediction of aggressive behavior. OBJECTIVE The focus of the study is to investigate whether exposures to 1) organized; and 2) family violence equally contribute to aggressive behavior and how this is related to a trait of appetitive aggression. Furthermore it is of interest to uncover how the severity of posttraumatic stress disorder (PTSD) symptoms modulates associations between violent experiences and aggression. METHOD To answer these questions, we investigated unaccompanied refugee minors who had been exposed to varying levels of both violence types. Using structured interviews, experiences of organized and familial violence, self-committed aggressive acts, the trait of appetitive aggression, and PTSD symptoms were assessed in 49 volunteers. RESULTS A sequential regression analysis revealed that the trait of appetitive aggression and experienced family violence were independent and significant predictors of self-committed aggressive acts, altogether accounting for 70% of the variance. Exposure to organized violence, however, was not significantly associated with aggressive acts or appetitive aggression. PTSD symptom severity was not correlated with measures of aggression but with the exposure to familial and organized violence. CONCLUSIONS Results suggest that in addition to the impact of family violence, an elevated trait of appetitive aggression plays a crucial role in aggressive behavior and should be considered in psychotherapeutic treatment.

Abstract
BACKGROUND Previous research reveals an association between traumatic stress and an increased risk for numerous diseases, including cancer. At the molecular level, stress may increase carcinogenesis via increased DNA damage and impaired DNA repair mechanisms. We assessed DNA breakage in peripheral blood mononuclear cells from individuals with post-traumatic stress disorder (PTSD) and measured the cellular capacity to repair single-strand breaks after exposure to ionizing X-radiation. We also investigated the effect of psychotherapy on both DNA breakage and DNA repair. METHODS In a first study we investigated DNA breakage and repair in 34 individuals with PTSD and 31 controls. Controls were subdivided into 11 trauma-exposed subjects and 20 individuals without trauma exposure. In a second study, we analysed the effect of psychotherapy (Narrative Exposure Therapy) on DNA breakage and repair. Thirty-eight individuals with PTSD were randomly assigned to either a treatment or a waitlist control condition. Follow-up was performed 4 months and 1 year after therapy. RESULTS In study 1 we found higher levels of basal DNA breakage in individuals with PTSD and trauma-exposed subjects than in controls, indicating that traumatic stress is associated with DNA breakage. However, single-strand break repair was unimpaired in individuals with PTSD. In study 2, we found that psychotherapy reversed not only PTSD symptoms, but also DNA strand break accumulation. CONCLUSION Our results show - for the first time in vivo - an association between traumatic stress and DNA breakage; they also demonstrate changes at the molecular level, i.e., the integrity of DNA, after psychotherapeutic interventions.

Obstetric care providers are able to assess psychosocial risks, identify and refer high-risk pregnant women: validation of a short assessment tool - the KINDEX Greek version. BMC Pregnancy Childbirth 2015; 15:41.

Abstract
Background Prenatal assessment for psychosocial risk factors and prevention and intervention is scarce and, in most cases, nonexistent in obstetrical care. In this study we aimed to evaluate if the KINDEX, a short instrument developed in Germany, is a useful tool in the hands of non-trained medical staff, in order to identify and refer women in psychosocial risk to the adequate mental health and social services. We also examined the criterion-related concurrent validity of the tool through a validation interview carried out by an expert clinical psychologist. Our final objective was to achieve the cultural adaptation of the KINDEX Greek Version and to offer a valid tool for the psychosocial risk assessment to the obstetric care providers. Methods Two obstetricians and five midwives carried out 93 KINDEX interviews (duration 20 minutes) with pregnant women to assess psychosocial risk factors present during pregnancy. Afterwards they referred women who they identified having two or more psychosocial risk factors to the mental health attention unit of the hospital. During the validation procedure an expert clinical psychologist carried out diagnostic interviews with a randomized subsample of 50 pregnant women based on established diagnostic instruments for stress and psychopathology, like the PSS-14, ESI, PDS, HSCL-25. Results Significant correlations between the results obtained through the assessment using the KINDEX and the risk areas of stress, psychopathology and trauma load assessed in the validation interview demonstrate the criterion-related concurrent validity of the KINDEX. The referral accuracy of the medical staff is confirmed through comparisons between pregnant women who have and have not been referred to the mental health attention unit. Conclusions Prenatal screenings for psychosocial risks like the KINDEX are feasible in public health settings in Greece. In addition, validity was confirmed in high correlations between the KINDEX results and the results of the validation interviews. The KINDEX Greek version can be considered a valid tool, which can be used by non-trained medical staff providing obstetrical care to identify high-risk women and refer them to adequate mental health and social services. These kind of assessments are indispensable for the promotion of a healthy family environment and child development.

Abstract
BACKGROUND Traumatic stress does not only increase the risk for posttraumatic stress disorder (PTSD), but is also associated with adverse secondary physical health outcomes. Despite increasing efforts, we only begin to understand the underlying biomolecular processes. The hypothesis-free assessment of a wide range of metabolites (termed metabolite profiling) might contribute to the discovery of biological pathways underlying PTSD. METHODS Here, we present the results of the first metabolite profiling study in PTSD, which investigated peripheral blood serum samples of 20 PTSD patients and 18 controls. We performed liquid chromatography (LC) coupled to Quadrupole/Time-Of-Flight (QTOF) mass spectrometry. Two complementary statistical approaches were used to identify metabolites associated with PTSD status including univariate analyses and Partial Least Squares Discriminant Analysis (PLS-DA). RESULTS Thirteen metabolites displayed significant changes in PTSD, including four glycerophospholipids, and one metabolite involved in endocannabinoid signaling. A biomarker panel of 19 metabolites classifies PTSD with 85% accuracy, while classification accuracy from the glycerophospholipid with the highest differentiating ability already reached 82%. CONCLUSIONS This study illustrates the feasibility and utility of metabolite profiling for PTSD and suggests lipid-derived and endocannabinoid signaling as potential biological pathways involved in trauma-associated pathophysiology.

Abstract
BACKGROUND The relationships between traumatic stress and self-conscious emotions, such as shame and guilt, remain to be fully explored, especially in refugees, who frequently are exposed to a multitude of stressors. OBJECTIVE The aim of the present study was to investigate shame and guilt in refugee minors and to assess to what extent a greater cumulative exposure to traumatic stressors would result not only in more severe posttraumatic stress disorder (PTSD) symptoms but also in higher levels of shame and guilt. METHODS Thirty-two male refugee minors, who were all below the age of 18 when they sought asylum in Germany, agreed to participate. At the time of the assessment, the age ranged from 11 to 20 years. Eighteen refugees had arrived without relatives in their host country ("unaccompanied minors"). In structured diagnostic interviews, a PTSD diagnosis was established using the UCLA PTSD Index. Posttraumatic guilt was assessed by means of the Trauma-related Guilt Inventory, and the Shame Variability Questionnaire was used to record the intensity, duration, and frequency of shame episodes. RESULTS Feelings of guilt and shame as well as trauma symptoms were all associated with the number of traumatic event types subjects had experienced. Posttraumatic guilt and shame were both correlated with PTSD symptom severity. CONCLUSIONS The findings indicate that cumulative stress such as exposure to multiple traumatic events poses a risk factor for the mental health including greater suffering and functional impairment due to shame and guilt.

Abstract
The evolutionary model of the defense cascade by Schauer and Elbert (2010) provides a theoretical frame for a short interview to assess problems underlying and leading to the dissociative subtype of posttraumatic stress disorder. Based on known characteristics of the defense stages "fright," "flag," and "faint," we designed a structured interview to assess the vulnerability for the respective types of dissociation. Most of the scales that assess dissociative phenomena are designed as self-report questionnaires. Their items are usually selected based on more heuristic considerations rather than a theoretical model and thus include anything from minor dissociative experiences to major pathological dissociation. The shutdown dissociation scale (Shut-D) was applied in several studies in patients with a history of multiple traumatic events and different disorders that have been shown previously to be prone to symptoms of dissociation. The goal of the present investigation was to obtain psychometric characteristics of the Shut-D (including factor structure, internal consistency, retest reliability, predictive, convergent and criterion-related concurrent validity). A total population of 225 patients and 68 healthy controls were accessed. Shut-D appears to have sufficient internal reliability, excellent retest reliability, high convergent validity, and satisfactory predictive validity, while the summed score of the scale reliably separates patients with exposure to trauma (in different diagnostic groups) from healthy controls. The Shut-D is a brief structured interview for assessing the vulnerability to dissociate as a consequence of exposure to traumatic stressors. The scale demonstrates high-quality psychometric properties and may be useful for researchers and clinicians in assessing shutdown dissociation as well as in predicting the risk of dissociative responding.

Abstract
BACKGROUND High levels of stress due to diverse psychosocial factors have a direct impact on the mothers' wellbeing during pregnancy and both direct and indirect effects on the fetus. In most cases, psychosocial risk factors present during pregnancy will not disappear after delivery and might influence the parent-child relationship, affecting the healthy development of the offspring in the long term. We introduce a short innovative prenatal assessment to detect psychosocial risk factors through an easy to use instrument for obstetrical medical staff in the daily clinical practice, the KINDEX Spanish Version. METHODS In the present study midwives and gynecologists interviewed one hundred nineteen pregnant women in a public health center using the KINDEX Spanish Version. Sixty-seven women were then randomly selected to participate in an extended standardized validation interview conducted by a clinical psychologist using established questionnaires to assesses current stress (ESI, PSS-14), symptoms of psychopathology (HSCL-25, PDS) and traumatic experiences (PDS, CFV). Ethical approval was granted and informed consent was required for participation in this study. RESULTS The KINDEX sum score, as assessed by medical staff, correlated significantly with stress, psychopathology and trauma as measured during the clinical expert interview. The KINDEX shows strong concurrent validity. Its use by medical staff in daily clinical practice is feasible for public health contexts. Certain items in the KINDEX are related to the respective scales assessing the same risks (e.g.PSS-4 as the shorter version of the PSS-14 and items from the ESI) used in the validation interview. CONCLUSIONS The KINDEX Spanish Version is a valid tool in the hands of medical staff to identify women with multiple psychosocial risk factors in public health settings. The KINDEX Spanish Version could serve as a base-instrument for the referral of at-risk women to appropriate psychosocial intervention. Such early interventions could prove pivotal in preventing undesirable mother-child relationships and adverse child development.

Abstract
BACKGROUND Traumatic stress leads to functional reorganization in the brain and may trigger an alarm response. However, when the traumatic event produces severe helplessness, the predominant peri-traumatic response may instead be marked by a dissociative shutdown reaction. The neural correlates of this dissociative shutdown were investigated by presenting rapidly presented affective pictures to female participants with posttraumatic stress disorder (PTSD), and comparing responses to a Non-PTSD control group. METHODS Event-related-magnetic-fields were recorded during rapid visual serial presentation of emotionally arousing stimuli (unpleasant or pleasant), which alternated with pictures with low affective content (neutral). Neural sources, based on the L2-surface-minimum-norm, correlated with the severity of the symptom clusters: PTSD, depression and shutdown dissociation. RESULTS For the early cortical response (60 to 110 ms), dissociation and PTSD symptom severity show similar spatial distributions of correlates for unpleasant stimuli. Cortical networks that could be involved in the relationships seem to be widespread. CONCLUSION We conclude that shutdown dissociation, PTSD and depression all have distinct effects on early processing of emotional stimuli.

Abstract
Posttraumatic stress disorder (PTSD) is associated with a reduced ratio of naïve cytotoxic T lymphocytes, an increased ratio of memory cytotoxic T lymphocytes, and a reduced proportion of FoxP3(+) regulatory T lymphocytes. This study investigated whether these immunological alterations are reversible through an evidence-based psychotherapeutic treatment. Therefore, 34 individuals with PTSD were randomly assigned to either a treatment condition of 12 sessions narrative exposure therapy (NET) or a waitlist control (WLC) group. PTSD symptoms were significantly reduced in the NET group, but not in the WLC group, four months post-therapy (effect size: Hedges' g = -1.61). One year after therapy, PTSD symptoms were improved even further in the NET group compared to baseline (Hedges' g = -1.96). This symptom improvement was mirrored in an increase in the originally reduced proportion of regulatory T cells (Tregs) in the NET group at the one-year follow-up, when comparing subgroups matched for baseline Treg numbers. However, no changes were found for the initially reduced proportion of CD45RA(+)CCR7(+) naïve T lymphocytes. In conclusion, NET was effective in reducing trauma-related PTSD symptoms and had a positive effect on the proportion of Tregs cells, thus demonstrating an effect of psychotherapy on an immunological level. Yet, the shift in the proportion of naïve and memory T lymphocytes in individuals with PTSD, discussed in the literature as a correlate of premature immunosenescence, was not reversible and thus might render these patients permanently more susceptible to infectious diseases.

Abstract
Hintergrund: Belastende Kindheitserfahrungen steigern das Risiko für Psychopathologie und beeinflussen die Erkrankungsschwere und den Behandlungserfolg. Validierte Instrumente zur umfangreichen Erfassung von Kindheitsbelastungen sind für die klinisch-psychologische Arbeit unabdingbar jedoch nur bedingt vorhanden. Fragestellung: Diese Arbeit stellt die Konstruktion und psychometrische Prüfung der Skala „Belastende Kindheitserfahrungen” (KERF), einem Instrument zur umfangreichen Erfassung von Kindheitsbelastungen vor. Die KERF beruht auf einer modifizierten Version des US-amerikanischen „Adversive Childhood Experiences” Index. Methode: Basierend auf den Daten von 165 Probandinnen wurden mit Rasch-Modellen zehn Subskalen modelliert. Korrelationen mit dem CTQ (Childhood Trauma Questionnaire) und Psychopathologie wurden bestimmt. Ergebnisse: Unterstützt durch konzeptuelle Überlegungen konnten zehn Subskalen gebildet werden. Wir fanden zufriedenstellende Assoziationen mit dem CTQ und Psychopathologie. Schlussfolgerungen: KERF ermöglicht eine detaillierte valide Erfassung belastender Kindheitserfahrungen.

Abstract
Hintergrund: Die Prävalenz von Traumafolgestörungen bei erwachsenen Flüchtlingen ist bekanntermaßen hoch. Gleichzeitig zeigen auch Flüchtlingskinder multiple psychische Auffälligkeiten und Funktionseinschränkungen. Theorien zu generationsübergreifender Traumatisierung vermuten, dass die Posttraumatische Belastungsstörung (PTBS) der Eltern sowie familiäre Gewalt die psychische Gesundheit der Kinder maßgeblich beeinflussen. Doch auch andere Faktoren wie eigene traumatische Erfahrungen im Herkunfts- und Aufnahmeland oder die Lebensbedingungen im Exil stehen möglicherweise mit der psychischen Gesundheit der Kinder in Zusammenhang. Fragestellung: Ziel der vorliegenden Arbeit ist es, den Zusammenhang von PTBS, weiteren Traumafolgeerkrankungen und Gewalterfahrungen von Flüchtlingsmüttern und ihren Kindern transgenerational zu untersuchen. Methode: 41 Flüchtlingsmütter und ihre Kinder (Alter 11-18 Jahre) wurden mit Hilfe von standardisierten, psychodiagnostischen Instrumenten unabhängig voneinander interviewt. Bei den Kindern wurde das Ausmaß der erlebten familiären Gewalt, erlebte traumatische Ereignisse, Ängstlichkeit, Depressivität sowie PTBS erfasst. Bei den Müttern wurde das Ausmaß der erlebten familiären Gewalt in der Kindheit, Gewalterfahrungen in der Partnerschaft in den letzten 12 Monaten ebenso wie andere traumatische Ereignisse sowie PTBS und Depressivität erhoben. Ergebnisse: Die Schwere der PTBS-Symptomatik bei den Müttern zeigt keinen direkten Zusammenhang mit der PTBS-Symptomatik, der Ängstlichkeit und der Depressivität der Kinder. Die Schwere der mütterlichen PTBS-Symptomatik ist aber mit der vom Kind erlebten familiären Gewalt positiv assoziiert. Die von den Kindern berichtete Anzahl unterschiedlicher traumatischer Ereignistypen und das Ausmaß der familiären Gewalt korrelieren wiederum positiv sowohl mit deren PTBS-Symptomatik als auch mit deren Depressivität und Ängstlichkeit. Schlussfolgerung: Die Ergebnisse veranschaulichen, dass nicht die PTBS-Symptomatik der Mutter, sondern die von den Kindern selbst erlebten traumatischen Erfahrungen, einschließlich der erlebten familiären Gewalt, mit den Traumafolgeerkrankungen der Kinder in Zusammenhang stehen. Die PTBS-Symptomatik der Mutter steht jedoch mit der vom Kind erlebten familiären Gewalt in Zusammenhang. Psychotherapeutische, trauma-fokussierte Interventionen sind daher sowohl für Mütter als auch Kinder indiziert. Darüber hinaus können Elterntrainings sinnvoll sein, um langfristig den Zyklus der Gewalt zu durchbrechen.

Abstract
People with post-traumatic stress disorder (PTSD) often suffer from memory disturbances. In particular, previous studies suggest that PTSD patients perform atypically on tests of directed forgetting, which may be mediated by an altered emotional appraisal of the presented material. Also, a special role of dissociative symptoms in traumatized individuals’ memory performance has been suggested. Here, we investigate these issues in traumatized immigrants in Germany. In an item-method directed forgetting task, pictures were presented individually, each followed by an instruction to either remember or forget it. Later, recognition memory was tested for all pictures, regardless of initial instruction. Overall, the PTSD group’s discrimination accuracy was lower than the control group’s, as PTSD participants produced fewer hits and more false alarms, but the groups did not differ in directed forgetting itself. Moreover, the more negatively participants evaluated the stimuli, the less they were able to discriminate old from new items. Participants with higher dissociation scores were particularly poor at recognizing to-be-forgotten items. Results confirm PTSD patients’ general discrimination deficits, but provide no evidence for a distinct directed forgetting pattern in PTSD. Furthermore, data indicate that, in general, more negatively perceived items are discriminated with less accuracy than more positively appraised ones. Results are discussed in the larger context of emotion and stress-related modulations of episodic memory, with particular focus on the role of dissociative symptoms.

Abstract
Many studies have reported that during high fertility points in the menstrual cycle, women demonstrate increased preference for men with masculinized faces and bodies. In this study, we analyzed whether appetitive aggression in men serves as an additional signal for a favored partner choice. Appetitive aggression describes the intrinsic motivation to act violently even when not being threatened. This study evaluated the responses of 1212 women to one of four descriptions regarding a soldier´s experience after returning from war. The four vignettes included trauma related symptoms with high or low appetitive aggression, or no trauma related symptoms with high or low appetitive aggression. Participants rated their desirability for the soldier in regards to potential long-term and short-term relationships. Results indicate that women preferred a soldier high in appetitive aggression as a short-term mate but not as a long-term relationship. This preference for the "warrior" was higher for women in their fertile window of the menstrual cycle. We conclude that women in their fertile window prefer men exhibiting higher appetitive aggression as a short-term partner, revealing appetitive aggression in men may serve as a signal for a higher genetic fitness.

Abstract
As a consequence of the ongoing conflict in the Democratic Republic of the Congo (DRC), combatants are constantly involved in various forms of violence. Findings concerning the impact of perpetrating violence on mental health are contradictory, ranging from increasing to buffering the risk for mental ill health. The present study investigated the impact of perpetrating violence on mental health. In total, 204 forcibly recruited and voluntary male combatants (mean age = 24.61 years) from different armed groups in the eastern DRC took part in the study. In a semistructured interview, respondents were questioned about appetitive aggression and posttraumatic stress disorder (PTSD) as well as self-experienced violence and self-perpetrated violent offending. A multivariate analysis of variance (η(2) = .23) revealed that voluntary combatants perpetrated more violent acts (η(2) = .06) and showed higher appetitive aggression η(2) = .03). A moderated multiple regression analysis (R(2) = .20) showed that perpetrating violence was positively related to PTSD in forcibly recruited combatants, but not in voluntary combatants. Thus, perpetrating violence may not necessarily qualify as a traumatic stressor. Further studies might consider assessing the combatant's perception of committing violent acts.

Abstract
BACKGROUND Child soldiers are often both victims and perpetrators of horrendous acts of violence. Research with former child soldiers has consistently shown that exposure to violence is linked to trauma-related disorders and that living in a violent environment is correlated with enhanced levels of aggression. OBJECTIVE To gain more insight into the experiences and the mental health status of former child soldiers, we conducted a survey with N=200 former child soldiers and adult combatants in the DR Congo. METHODS We conducted semi-structured interviews concerning military experiences, experienced and perpetrated violence, and mental health. RESULTS Former child soldiers reported more experienced and perpetrated violence, a greater severity of trauma-related suffering, as well as higher appetitive aggression than adult ex-combatants. Appetitive aggression was related to more perpetrated violence, higher military ranks, voluntary recruitment and higher rates of reenlistments in former child soldiers. CONCLUSIONS Our results indicate that growing up in an armed group is related to higher levels of trauma-related disorders and aggressive behavior. This may explain the challenge of reintegrating former child soldiers. It is thus important to consider mental health problems, particularly trauma-related disorders and aggressive behavior, of former child soldiers for designing adequate reintegration programs.

Abstract
BACKGROUND In the ongoing conflict in the Democratic Republic of the Congo (DRC), combatants are exposed to massive forms of violence and other traumatic stressors. Nevertheless, many combatants do not suffer from trauma-related disorders, although they have experienced numerous traumatizing events. Perceiving aggressive behavior as fascinating and arousing might be a defense against trauma-related disorders in the violent environment of war and conflict. OBJECTIVE Thus, in this study we investigated the relationship between the exposure to traumatic stressors, appetitive aggression, and posttraumatic stress disorder (PTSD) symptom severity. We hypothesized that cumulative traumatic experiences correlated positively and appetitive aggression negatively with PTSD symptom severity. METHOD In total, 105 voluntary male combatants from different armed groups in the eastern DRC took part in this study. In a semistructured interview, respondents were questioned about their exposure to traumatic stressors, the extent of appetitive aggression (Appetitive Aggression Scale) and their PTSD symptom severity (PTSD Symptom Scale - Interview). RESULTS A multiple sequential regression analysis showed that traumatic events were positively related to PTSD symptom severity. For participants with low to medium PTSD symptom severity, appetitive aggression correlated negatively with PTSD symptom severity. CONCLUSIONS The results of this study provide further support for earlier findings that repeated exposure to traumatic stressors cumulatively heightens the risk of PTSD and revealed that appetitive aggression buffers the risk of developing PTSD symptoms under certain circumstances. Thus, the perception of aggressive behavior as fascinating and arousing seem to help combatants to adapt to violent environments but may also be one reason for recurrent failure of reintegration programs for excombatants.

Abstract
BACKGROUND An earlier published series of neoadjuvant radiochemotherapy (NRT-CHX) in locally advanced noninflammatory breast cancer (LABC) has now been updated with a follow-up of more than 15 years. Long-term outcome data and predictive factors for pathologic complete response (pCR) were analyzed. PATIENTS AND METHODS During 1991-1998, 315 LABC patients (cT1-cT4/cN0-N1) were treated with NRT-CHX. Preoperative radiotherapy (RT) consisted of external beam radiation therapy (EBRT) of 50 Gy (5 × 2 Gy/week) to the breast and the supra-/infraclavicular lymph nodes combined with an electron boost in 214 cases afterwards or-in case of breast conservation-a 10-Gy interstitial boost with (192)Ir afterloading before EBRT. Chemotherapy was administered prior to RT in 192 patients, and concomitantly in 113; 10 patients received no chemotherapy. The update of all follow-up ended in November 2011. Age, tumor grade, nodal status, hormone receptor status, simultaneous vs. sequential CHX, and the time interval between end of RT and surgery were examined in multivariate terms with pCR and overall survival as end point. RESULTS The total pCR rate after neoadjuvant RT-CHX reached 29.2%, with LABC breast conservation becoming possible in 50.8% of cases. In initially node-positive cases (cN+), a complete nodal response (pN0) after NRT-CHX was observed in 56% (89/159). The multivariate analysis revealed that a longer time interval to surgery increased the probability for a pCR (HR 1.17 [95% CI 1.05-1.31], p < 0.01). However, in large tumors (T3-T4) a significantly reduced pCR rate (HR 0.89 [95% CI 0.80-0.99], p = 0.03) was obtained. Importantly, pCR was the strongest prognostic factor for long-term survival (HR 0.28 [95% CI 0.19-0.56], p < 0.001). CONCLUSION pCR identifies patients with a significantly better prognosis for long-term survival. However, a long time interval to surgery (> 2 months) increases the probability of pCR after NRT-CHX.

Abstract
Esophageal perforations are life threatening emergencies associated with high morbidity and mortality. We report on 22 consecutive patients (age 20-86; 13 female and 9 male) with an oesophageal perforation treated at the university hospital Duesseldorf. The patients' charts were reviewed and follow-up was completed for all patients until demission, healed reconstruction or death. Patients' history, clinical presentation, time interval to surgical presentation, and treatment modality were recorded and correlated with patients' outcome. Six esophageal perforations were due to a Boerhaave-syndrome, eleven caused by endoscopic perforation, two after osteosynthesis of the cervical spine and three foreign body induced. In 7 patients a primary local suture was performed, in 4 cases a supplemental muscle flap was interposed, and 7 patients underwent an oesophageal resection. Four patients were treated without surgery (three esophageal stent implantations, one conservative treatment). Eleven patients (50 %) were presented within 24 h of perforation, and 11 patients (50 %) afterwards. Time delay correlates with survival. In 17 (80.9 %) cases a surgical sufficient reconstruction could be achieved. One (4.7 %) patient is waiting for reconstruction after esophagectomy. Four (18.2 %) patients died. A small subset of patients can be treated conservatively by stenting of the Esophagus, if the patient presents early. In the majority of patients a primary repair (muscle flap etc.) can be performed with good prognosis. If the patient presents delayed with extensive necrosis or mediastinitis, oesophagectomy and secondary repair is the only treatment option with high mortality.

Abstract
Soldiers and combatants often report that committing violence can be appealing, fascinating and exciting (Elbert, Weierstall, & Schauer, 2010). This appetite for aggression was investigated in a sample of 224 former combatants from different armed groups and forces in eastern DRC. In a semistructured interview they were questioned about their military history, exposure to violence and perpetrated violence. Appetitive aggression was assessed with a 15-item-scale (Weierstall & Elbert, 2011), which was successfully implemented in comparable samples (Weierstall, Schalinski, Crombach, Hecker, & Elbert, submitted for publication). A sequential multiple regression was conducted to determine possible predictors of appetitive aggression. Perpetrated violence types, recruitment type, and joining as a child were significant predictors and explained 26% of the variability in appetitive aggression. Duration or military rank within the armed group and exposure to violence did not play a significant role. Thus, combatants reporting high levels of appetitive aggression are characterized by perpetrating a high number of violent acts, joining armed groups on their own accord and as children. Joining an armed group on one's own accord indicates pre-existing appetitive aggression. However, joining young and perpetrating violence on a regular basis seem to intensify the appetite for aggression.
