  abstract  = {Bruxismus bezeichnet eine sich wiederholende Kaumuskelaktivit{\"a}t mit Knirschen oder Aufeinanderpressen der Z{\"a}hne. W{\"a}hrend bei Erwachsenen die Ursachen und die Pathophysiologie schon weitreichend erforscht wurden, gab es bei Kindern bislang keine systematische Untersuchung hinsichtlich des Zusammenhangs mit psychopathologischen Faktoren. Deshalb wurde unsere Studie nun erstmals mit Bruxismusmessung nach Goldstandard sowie mit normierten und validierten Frageb{\"o}gen zu verschiedenen psychosozialen Dimensionen als Querschnittsuntersuchung bei 53 acht- bis zw{\"o}lfj{\"a}hrigen Kindern durchgef{\"u}hrt. Besonderes Augenmerk wurde dabei auf den hypothetisierten Zusammenhang zwischen Schlafbruxismus und Angstsensitivit{\"a}t sowie Angstintensit{\"a}t gelegt. Außerdem wurde der Einfluss weiterer psychosozialer Faktoren (wie Lebensqualit{\"a}t, Anzahl negativer Lebensereignisse, Verhaltensauff{\"a}lligkeiten, ADHS-Symptomatik, depressive Symptomatik, Zwangssymptomatik, Ticsymptomatik, Alter und Geschlecht) auf die o.g. Pr{\"a}diktoren per multipler Regressionsanalyse gepr{\"u}ft. Auf Basis der durchgef{\"u}hrten Untersuchung ergaben sich keine Hinweise auf eine Assoziation von Bruxismus zu psychosozialen Dimensionen. Die vorbeschriebenen Zusammenh{\"a}nge erwiesen sich als statistisch nicht signifikant. Dies mag zum einen der Stichprobenauswahl von gesunden Kindern geschuldet sein, die weder von Bruxismus noch von anderen Faktoren vorbekannt klinisch beeintr{\"a}chtigt waren. Andererseits k{\"o}nnen aber auch fehlerhafte Ausgangs{\"u}berlegungen durch nicht dem Goldstandard entsprechenden Messungen der Vorstudien zu diesem Ergebnis gef{\"u}hrt haben. Dar{\"u}ber hinaus verl{\"a}uft die Kindesentwicklung interindividuell sehr variabel und tempor{\"a}re myofunktionelle Beeintr{\"a}chtigungen k{\"o}nnen ohne Bezug zu psychischer Belastung auftreten.},

  abstract  = {Background: Approximately 10\% of children, adolescents and young adults with an intellectual and developmental disability (IDD) in Bavaria live in residential institutions. 2015 saw media reports raising suspicions about excessive use of coercive measures (cM) in those institutions. Until a law reform at the end of 2017 made permission from family courts mandatory for cM, their use was governed by parental consent. The REDUGIA project conducted a representative survey comparing cM and their relation to challenging behaviour (cB) and employee stress in Bavaria pre and post reform. Methods: We sent questionnaires to 65 residential institutions for children, adolescents and young adults with IDD in 2017 (pre reform, T1) and 2019 (post reform, T2). To assess changes, we analysed data from all available questionnaire pairs (T1 and T2, N = 43). We calculated paired t-test and correlative analyses concerning the relationship between cB, cM, and employee stress. Results: The number of residents overall (T1: N = 1,661; T2: N = 1,673) and per institution (T1: m = 38.6 ± 32.0; T2: m = 38.9 ± 34.5, p = 0.920) remained stable. We did not see any changes in the Index cB (p = 0.508) or the proportion of residents per institution displaying various types of challenging behaviour (all ps>0.220). There was no change in the Index cM (p = 0.089) or any indicator of employee stress, all ps > 0.323. At follow-up, the Index cB correlated positively with the Index cM (r = 0.519 p < 0.001). Regarding employee stress, the Index cB correlated positively with the frequency of sick leave (r = 0.322, p = 0.037) and physical attacks on employees (r = 0.552, p < 0.001). The Index cM also correlated positively with the frequency of sick leave (r = 0.340, p = 0.028) and physical attacks on employees (r = 0.492, p = 0.001). Discussion: Coercive measures are not a general phenomenon, but are focused on specialised institutions. The law reform did not lead to changes in the number of children, adolescents and young adults with IDD affected by coercive measures in residential institutions in Bavaria. There were still large discrepancies between institutions in the prevalence of challenging behaviour and coercive measures. Coercive measures were associated with challenging behaviour and employee stress. Taken together, findings from REDUGIA emphasise the need to prevent challenging behaviour and thus coercive measures.},

  abstract  = {Background: The Catechol-O-methyltransferase (COMT) represents the key enzyme in catecholamine degradation. Recent studies suggest that the COMT rs4680 polymorphism is associated with the response to endogenous and exogenous catecholamines. There are, however, conflicting data regarding the COMT Met/Met phenotype being associated with an increased risk of acute kidney injury (AKI) after cardiac surgery. The aim of the current study is to prospectively investigate the impact of the COMT rs4680 polymorphism on the incidence of AKI in patients undergoing cardiac surgery. Methods: In this prospective single center cohort study consecutive patients hospitalized for elective cardiac surgery including cardiopulmonary-bypass (CPB) were screened for participation. Demographic clinical data, blood, urine and tissue samples were collected at predefined time points throughout the clinical stay. AKI was defined according to recent recommendations of the Kidney Disease Improving Global Outcome (KDIGO) group. Genetic analysis was performed after patient enrolment was completed. Results: Between April and December 2014, 150 patients were recruited. The COMT genotypes were distributed as follows: Val/Met 48.7\%, Met/Met 29.3\%, Val/Val 21.3\%. No significant differences were found for demography, comorbidities, or operative strategy according to the underlying COMT genotype. AKI occurred in 35 patients (23.5\%) of the total cohort, and no differences were evident between the COMT genotypes (20.5\% Met/Met, 24.7\% Val/Met, 25.0\% Val/Val, p = 0.66). There were also no differences in the post-operative period, including ICU or in-hospital stay. Conclusions: We did not find statistically significant variations in the risk for postoperative AKI, length of ICU or in-hospital stay according to the underlying COMT genotype.},

  abstract  = {Most research on human fear conditioning and its generalization has focused on adults whereas only little is known about these processes in children. Direct comparisons between child and adult populations are needed to determine developmental risk markers of fear and anxiety. We compared 267 children and 285 adults in a differential fear conditioning paradigm and generalization test. Skin conductance responses (SCR) and ratings of valence and arousal were obtained to indicate fear learning. Both groups displayed robust and similar differential conditioning on subjective and physiological levels. However, children showed heightened fear generalization compared to adults as indexed by higher arousal ratings and SCR to the generalization stimuli. Results indicate overgeneralization of conditioned fear as a developmental correlate of fear learning. The developmental change from a shallow to a steeper generalization gradient is likely related to the maturation of brain structures that modulate efficient discrimination between danger and (ambiguous) safety cues.},

Im Rahmen des Projekts REDUGIA wurde in bayerischen Heimeinrichtungen eine repr{\"a}sentative Erhebung zu freiheitsentziehenden Maßnahmen (FeM), herausforderndem Verhalten (hfV) und der Mitarbeiterbelastung (MaB) durchgef{\"u}hrt. Methodik: 65 Einrichtungen f{\"u}r junge Menschen mit Intelligenzminderung in Bayern wurde ein Fragebogen zu strukturellen Gegebenheiten sowie MaB, hfV und FeM zugesendet. Neben deskriptiven Auswertungen wurden korrelative Analysen bzw. Regressionsanalysen zum Zusammenhang zwischen hfV, FeM und MaB durchgef{\"u}hrt. Ergebnisse: Es wurden Daten zu 1839 Personen in 61 Einrichtungen erhoben. 84.3 \% der Einrichtungen berichteten geringe Raten an hfV und FeM, w{\"a}hrend 15.7 \% ein geh{\"a}uftes Vorkommen von hfV und FeM angaben. Auf n = 1809 Vollzeit{\"a}quivalente kam es innerhalb von 14 Tagen zu 639 k{\"o}rperlichen Angriffen durch Bewohner_innen. In 12 Monaten wurden problemverhaltensassoziiert 85 Krankmeldungen sowie 33 Versetzungsantr{\"a}ge/K{\"u}ndigungen berichtet. Es zeigte sich ein signifikant positiver Zusammenhang zwischen hfV und FeM (R² = .307, F = 21.719, p < .001). Die Mitarbeiterbelastung korrelierte positiv mit hfV (r = .507, p < .001). Schlussfolgerungen: Die Studienbefunde weisen darauf hin, dass hfV sowie FeM bei jungen Menschen mit Intelligenzminderung kein fl{\"a}chendeckendes Ph{\"a}nomen darstellen, sondern sich auf wenige spezialisierte Einrichtungen fokussieren.

  abstract  = {Traditionally, adversity was defined as the accumulation of environmental events (allostatic load). Recently however, a mismatch between the early and the later (adult) environment (mismatch) has been hypothesized to be critical for disease development, a hypothesis that has not yet been tested explicitly in humans. We explored the impact of timing of life adversity (childhood and past year) on anxiety and depression levels (N = 833) and brain morphology (N = 129). Both remote (childhood) and proximal (recent) adversities were differentially mirrored in morphometric changes in areas critically involved in emotional processing (i.e. amygdala/hippocampus, dorsal anterior cingulate cortex, respectively). The effect of adversity on affect acted in an additive way with no evidence for interactions (mismatch). Structural equation modeling demonstrated a direct effect of adversity on morphometric estimates and anxiety/depression without evidence of brain morphology functioning as a mediator. Our results highlight that adversity manifests as pronounced changes in brain morphometric and affective temperament even though these seem to represent distinct mechanistic pathways. A major goal of future studies should be to define critical time periods for the impact of adversity and strategies for intervening to prevent or reverse the effects of adverse childhood life experiences.},

  abstract  = {Background: Diagnostic guidelines recommend using a variety of methods to assess and diagnose ADHD. Applying subjective measures always incorporates risks such as informant biases or large differences between ratings obtained from diverse sources. Furthermore, it has been demonstrated that ratings and tests seem to assess somewhat different constructs. The use of objective measures might thus yield valuable information for diagnosing ADHD. This study aims at evaluating the role of objective measures when trying to distinguish between individuals with ADHD and controls. Our sample consisted of children (n = 60) and adults (n = 76) diagnosed with ADHD and matched controls who completed self- and observer ratings as well as objective tasks. Diagnosis was primarily based on clinical interviews. A popular pattern recognition approach, support vector machines, was used to predict the diagnosis. Results: We observed relatively high accuracy of 79\% (adults) and 78\% (children) applying solely objective measures. Predicting an ADHD diagnosis using both subjective and objective measures exceeded the accuracy of objective measures for both adults (89.5\%) and children (86.7\%), with the subjective variables proving to be the most relevant. Conclusions: We argue that objective measures are more robust against rater bias and errors inherent in subjective measures and may be more replicable. Considering the high accuracy of objective measures only, we found in our study, we think that they should be incorporated in diagnostic procedures for assessing ADHD.},

  abstract  = {Background: Methylphenidate (MPH) is the first-line pharmacological treatment of attention-deficit/hyperactivity disorder (ADHD). MPH binds to the dopamine (DA) transporter (DAT), which has high density in the striatum. Assessments of the striatal dopamine transporter by single positron emission computed tomography (SPECT) in childhood and adolescent patients are rare but can provide insight on how the effects of MPH affect DAT availability. The aim of our within-subject study was to investigate the effect of MPH on DAT availability and how responsivity to MPH in DAT availability is linked to clinical symptoms and cognitive functioning. Methods Thirteen adolescent male patients (9-16 years) with a diagnosis of ADHD according to the DSM-IV and long-term stimulant medication (for at least 6 months) with MPH were assessed twice within 7 days using SPECT after application of I-123-β-CIT to examine DAT binding potential (DAT BP). SPECT measures took place in an on- and off-MPH status balanced for order across participants. A virtual reality continuous performance test was performed at each time point. Further clinical symptoms were assessed for baseline off-MPH. Results On-MPH status was associated with a highly significant change (-29.9\%) of striatal DAT BP as compared to off-MPH (t = -4.12, p = 0.002). A more pronounced change in striatal DAT BP was associated with higher off-MPH attentional and externalizing symptom ratings (Pearson r = 0.68, p = 0.01). Striatal DAT BP off-MPH, but not on-MPH, was associated with higher symptom ratings (Pearson r = 0.56, p = 0.04). Conclusion Our findings corroborate previous reports from mainly adult samples that MPH changes striatal DAT BP availability and suggest higher off-MPH DAT BP, likely reflecting low baseline DA levels, as a marker of symptom severity.},

  abstract  = {According to theories on moral balancing, a prosocial act can decrease people's motivation to engage in subsequent prosocial behavior, because people feel that they have already achieved a positive moral self-perception. However, there is also empirical evidence showing that people actually need to be recognized by others in order to establish and affirm their self-perception through their prosocial actions. Without social recognition, moral balancing could possibly fail. In this paper, we investigate in two laboratory experiments how social recognition of prosocial behavior influences subsequent moral striving. Building on self-completion theory, we hypothesize that social recognition of prosocial behavior (self-serving behavior) weakens (strengthens) subsequent moral striving. In Study 1, we show that a prosocial act leads to less subsequent helpfulness when it was socially recognized as compared to a situation without social recognition. Conversely, when a self-serving act is socially recognized, it encourages subsequent helpfulness. In Study 2, we replicate the effect of social recognition on moral striving in a more elaborated experimental setting and with a larger participant sample. We again find that a socially recognized prosocial act leads to less subsequent helpfulness compared to an unrecognized prosocial act. Our results shed new light on the boundary conditions of moral balancing effects and underscore the view that these effects can be conceptualized as a dynamic of self-completion.},
