Resting state fMRI has been employed to identify alterations in functional connectivity within or between brain regions following acute and chronic exposure to Δ9-tetrahydrocannabinol (THC), the psychoactive component in cannabis. Most studies focused a priori on a limited number of local brain areas or circuits, without considering the impact of cannabis on wholebrain network organization. The present study attempted to identify changes in the wholebrain human functional connectome as assessed with ultra-high field (7T) resting state scans of occasional (N=12) and chronic cannabis users (N=14) during placebo and following vaporization of cannabis. Two distinct data-driven methodologies, i.e. network-based statistics (NBS) and connICA, were used to identify changes in functional connectomes associated with acute cannabis intoxication and chronic cannabis use. Both methodologies revealed a broad state of hyperconnectivity within the entire range of major brain networks in chronic cannabis users compared to occasional cannabis users, which might be reflective of an adaptive network reorganization following prolonged cannabis exposure. The connICA methodology also extracted a distinct spatial connectivity pattern of hypoconnectivity involving the dorsal attention, limbic, subcortical and cerebellum networks and of hyperconnectivity between the default mode and ventral attention network, that was associated with the feeling of subjective high during THC intoxication across both user groups. Whole-brain network approaches identified spatial patterns in functional brain connectomes that distinguished acute from chronic cannabis use, and offer an important utility for probing the interplay between short and long-term alterations in functional brain dynamics when progressing from occasional to chronic use of cannabis.
Child sexual abuse has been discussed thoroughly; however, marginalized groups of victims such as victims of child sexual abuse in early childhood and victims of maternal sexual abuse have rarely been considered. This essay combines these two relevant perspectives in child protection and aims to pin out future directions in the field of child abuse and specifically maternal sexual abuse and its early prevention. In the course of the 7th Haruv International PhD Workshop on Child Maltreatment at the Hebrew University, Jerusalem, in 2019 the topics of maternal sexual abuse and early prevention of child maltreatment in Germany were discussed and intertwined. Problems concerning the specific research of maternal sexual abuse in early childhood and prevention were identified. Both, maternal sexual abuse as well as sexual abuse in early childhood, i.e. before the age of three, are underreported topics. Society still follows a “friendly mother illusion” while recent cases in German media as well as research findings indicate that the mother can be a perpetrator of child sexual abuse. Similarly, sexual abuse in early childhood, namely abuse before the age of three, is existent; although the recognition of it is difficult and young children are, in regards to their age and development especially vulnerable. They need protective adults in their environment, who are aware of sexual abuse in the first years of life. Raising awareness on marginalized or tabooed topics can be a form of prevention. An open dialog in research and practice about the so far marginalized topics of maternal sexual abuse and sexual abuse in early childhood is crucial.

Objective: Prisoners constitute a high-risk group for suicide, with suicide rates about 5 to 8 times higher than in the general population. The first weeks of imprisonment are a particularly vulnerable time, but there is limited knowledge about the risk factors for either early or late suicide events. Methods: Based on a national total sample of prison suicides in Germany between 2005 and 2017, suicides within the first 2 (4 and 8) weeks after reception into prison were matched by age and penalty length with cases that occurred later. Factors that potentially influence the timing of suicide were investigated. Results: The study has shown that 16.7% (31.5%) of all 390 suicides in German prisons occurred within the first two weeks (two months) of imprisonment. Factors that facilitate adaptation to the prison environment (e.g. prior prison experience) were negatively associated with early suicide events. Factors that hindered the adaptation process (e.g. withdrawal from illicit drugs) were observed more frequently in early suicide events than in late ones. These factors are active at different times of imprisonment. Conclusion: At reception, particular attention should be paid to the following factors associated with early suicide events: widowed marital status, lack of prison experience, and drug dependency.
Bisherige Forschungsergebnisse zeigen, dass auch Frauen sexuellen Kindesmissbrauch begehen und somit eine potentielle Gefahr für das Kindeswohl darstellen können. Aus Deutschland liegen bisher nur regionale oder Studien mit geringer Stichprobengröße vor. Die vorliegende Studie verfolgt das Ziel, eine umfassende Bestandserhebung des sexuellen Kindesmissbrauchs durch Frauen in Deutschland zu dokumentieren. Im Rahmen der vorliegenden Untersuchung wurden zum ersten Mal bundesweit Strafakten von 465 pädokriminellen Frauen ausgewertet, die in den letzten 30 Jahren nach §§174, 176, 180 oder 182 des StGB verurteilt wurden. Die standardisierte Analyse umfasst 185 Variablen und 54 selbst definierte Skalen. Die Ergebnisse zeigen, dass eine pädokriminelle Frau durchschnittlich 33 Jahre alt ist, zumeist in einer Ehe in einer Kleinstadt lebt und häufig keiner beruflichen Tätigkeit nachgeht. Sie ist eine Mittäterin, handelt überwiegend aus Abhängigkeit zu ihrem männlichen Komplizen heraus, zu dem sie eine intime Beziehung pflegt und missbraucht mehrheitlich weibliche Opfer (Verhältnis fast 2:1). Beinahe die Hälfte der 614 Opfer, zu denen Informationen vorlagen, waren leibliche Kinder der Täterinnen und rund jedes sechste Kind stammte vom männlichen Mittäter.
Für die Studie 2019 wurden Jugendliche aus 88 Klassen in 23 Schulen von Ende 2019 bis Anfang 2020 befragt. Sie waren im Durchschnitt 16,7 Jahre alt, 81 Prozent der Befragten wohnten in Frankfurt. Die Daten des Monitoring-System Drogentrends basieren auf Befragungen von jährlich ca. 1500 Frankfurter Schüler*innen, die das Centre for Drug Research der Goethe-Universität Frankfurt seit 2002 durchführt. An den hier dargestellten Ergebnissen der Hauptzielgruppe der 15- bis 18-Jährigen waren ca. 1100 Schüler*innen beteiligt. Ebenfalls abgefragt wurde in der MoSyD-Studie Medienkonsum, Glücksspiel und andere Freizeitaktivitäten. Die MoSyD-Studie (Monitoring-System Drogentrends) 2019 umfasst neben der Befragung der Schüler*-innen auch die Befragung von Expert*innen und Trendscouts. Das Drogenreferat der Stadt Frankfurt am Main fördert die Studie. Die gesamte Studie kann kostenfrei heruntergeladen werden unter https://www.uni-frankfurt.de/99133712/MoSyD_Jahresbericht_2019.pd
