Cannabis is the most commonly used illicit drug in the world. However, because of a changing legal landscape and rising interest in therapeutic utility, there is an increasing trend in (long-term) use and possibly cannabis impairment. Importantly, a growing body of evidence suggests that regular cannabis users develop tolerance to the impairing, as well as the rewarding, effects of the drug. However, the neuroadaptations that may underlie cannabis tolerance remain unclear. Therefore, this double-blind, randomized, placebo-controlled, cross-over study assessed the acute influence of cannabis on the brain and behavioral outcomes in two distinct cannabis user groups. Twelve occasional and 12 chronic cannabis users received acute doses of cannabis (300-μg/kg delta-9-tetrahydrocannabinol) and placebo and underwent ultrahigh field functional magnetic resonance imaging and magnetic resonance spectroscopy. In occasional users, cannabis induced significant neurometabolic alterations in reward circuitry, namely, decrements in functional connectivity and increments in striatal glutamate concentrations, which were associated with increases in subjective high and decreases in performance on a sustained attention task. Such changes were absent in chronic users. The finding that cannabis altered circuitry and distorted behavior in occasional, but not chronic users, suggests reduced responsiveness of the reward circuitry to cannabis intoxication in chronic users. Taken together, the results suggest a pharmacodynamic mechanism for the development of tolerance to cannabis impairment, of which is important to understand in the context of the long-term therapeutic use of cannabis-based medications, as well as in the context of public health and safety of cannabis use when performing day-to-day operations.

In a significant number of cases, clerical sex offenders impregnate their victims and force them into hiding, abortion, or adoption. This phenomenon is referred to in this paper as reproductive abuse. Clearly, most victims of reproductive abuse are adults, but even among minor victims of clerical child abuse, between 1 and 10 percent may have experienced reproductive abuse. On the basis of pertinent studies, this paper explores archival material on several dozen allegations of reproductive abuse in the context of clergy sexual abuse of minors in the US Catholic Church. Besides some tentative estimates of the general frequency of the phenomenon, this paper offers a distinction of three different types of reproductive abuse and an analysis of the interplay of clericalist and secular misogyny, which appears to be largely responsible for the silencing of victims as well as for the impunity of perpetrators and leads to the invisibility of this phenomenon, despite the high importance attributed to reproductive issues in the Catholic context.
In this article, we examine anti-refugee hate crime in the wake of the large influx of refugees to Germany in 2014 and 2015. By exploiting institutional features of the assignment of refugees to German regions, we estimate the impact of unexpected and sudden large-scale immigration on hate crime against refugees. Results indicate that it is not simply the size of local refugee inflows which drives the increase in hate crime, but rather the combination of refugee arrivals and latent anti-refugee sentiment. We show that ethnically homogeneous areas, areas which experienced hate crimes in the 1990s, and areas with high support for the Nazi party in the Weimar Republic, are more prone to respond to the arrival of refugees with incidents of hate crime against this group. Our results highlight the importance of regional anti-immigration sentiment in the analysis of the incumbent population’s reaction to immigration.
Zielsetzung: Untersuchung der Auswirkungen der Covid-19-Pandemie auf Angebote der vor allem niedrigschwelligen Drogenhilfe und Reaktionen der Klientel auf geänderte Angebote. Methodik: Verwendet wurden in erster Linie Daten aus einer asynchronen qualitativen Onlinebefragung für Mitarbeiter_innen der ambulanten Drogenhilfe, ergänzt durch Zahlen aus einer quantitativen Onlinebefragung für dieselbe Zielgruppe. Ergebnisse: Während übliche Infektionsschutzmaßnahmen nahezu überall angewendet wurden, reichte die Spanne der tatsächlichen Auswirkungen von Komplettschließungen bis zu eher geringen Einschränkungen. Schwerpunkte wurden zumeist auf Überlebenshilfe und Straßensozialarbeit gelegt. Beratung wurde oft per Telefon durchgeführt, was für viele Anliegen als sinnvoll erachtet wurde, Beziehungsarbeit aber erschwerte. Vor allem stark verelendete Klient_innen nutzten weiterhin häufig Hilfsangebote. Schlussfolgerungen: Es zeigen sich unterschiedliche Umgangsweisen der Drogenhilfe mit den pandemiebedingten Maßnahmen. Oft entwickelte man kreative Lösungen zur Umsetzung, mit Schwerpunktsetzung auf Existenzsicherung. Sowohl Mitarbeiter_innen als auch Klientel waren durch die Pandemie zahlreichen Belastungen ausgesetzt.
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.
Die Paulinenpflege Winnenden e.V. wurde 1823 gegründet als Rettungshaus für verwahrloste Kinder. Bald wurde daraus eine Doppelanstalt einerseits für Kinder, die aus sozialen Gründen nicht zuhause leben konnten, andererseits für hör- und sprachbehinderte Kinder. Zum 200-jährigen Jubiläum im Jahr 2023 erscheint dieses wissenschaftliche Werk. Dieses Werk erscheint zusätzlich in weitgehend identischer Weise als Buch.
Hintergrund: Depressionen sind häufige, schwere und oft lebensbedrohliche Erkrankungen, bei denen es – trotz sehr guter Behandlungsmethoden – Versorgungslücken gibt. Hierzu tragen Vorbehalte gegen eine leitlinienkonforme pharmako- und/oder psychotherapeutische Behandlung bei. Ziel der Arbeit ist es zu ermitteln, in welchen soziodemographischen Bevölkerungssegmenten diese Vorbehalte besonders ausgeprägt sind.
Methodik: Die Untersuchung basiert auf Online-Befragungen der deutschen Bevölkerung aus den Jahren 2021, 2020 und 2019, darunter 1656 Personen (2021), 1775 Personen (2020) und 1729 Personen (2019) ohne Depressionserfahrungen. Mit einer CHAID-Analyse wurde geprüft, in welchen Bevölkerungssegmenten die Vorbehalte gegen eine leitliniengerechte Behandlung besonders groß sind.
Ergebnisse: Vorbehalte gegen Pharmakotherapie hatten insgesamt 69,8 % der Befragten ohne Depressionserfahrungen. Am größten waren die Vorbehalte unter jüngeren Personen (< 40 Jahre); hier lag der Anteil bei 74,2 %. Vorbehalte gegen Psychotherapie äußerten 31,4 % ohne Depressionserfahrungen; unter Frauen mit geringerer Schulbildung hatten 40,5 % Vorbehalte gegen eine Psychotherapie; unter Männern mit geringerer Schulbildung waren es 39,1 %. Vorbehalte gegen beide Behandlungsformen zeigten 27,7 %. Am größten waren die Vorbehalte unter Männern mit Schulbildung unterhalb der Hochschulreife (34,1 %). Die Ergebnisse sind signifikant (χ2-Test, p < 0,05).
Diskussion: Eine allgemeine Informationsstrategie wäre geeignet, Vorbehalten gegen Pharmakotherapie und Psychotherapie gleichermaßen zu verringern. Für eine spezifische Informationsstrategie müssen die Botschaften hinsichtlich Inhalt und Kommunikationskanälen so gestaltet werden, dass die jüngere Zielgruppe zuverlässig erreicht wird.

Der Ukrainekrieg und seine psychologischen Folgen : Hilfe für Geflüchtete in Frankfurt und vor Ort
(2022)
Die Psychosoziale Beratungsstelle für Flüchtlinge der Goethe-Universität (PBF) unter Leitung von Prof. Dr. Ulrich Stangier beschäftigt sich angesichts der aktuellen Zuwanderung Geflüchteter aus der Ukraine mit den psychischen Folgen von Migration und Flucht im Rahmen der Ukrainekrise. Durch die Unterstützung der Freunde und Förderer der Goethe-Universität sowie die Polytechnische Gesellschaft konnten in Kooperation mit der Stadt Frankfurt die Angebote der Beratungsstelle an den gestiegenen Bedarf und die Bedürfnisse ukrainischer Geflüchteter angepasst werden. Weiterhin werden im Rahmen einer Kooperation mit ukrainischen Kolleg*innen in der Ukraine Workshops zum Umgang mit psychischen Kriegsfolgen angeboten.
Background: Predicted increases in suicide were not generally observed in the early months of the COVID-19 pandemic. However, the picture may be changing and patterns might vary across demographic groups. We aimed to provide a timely, granular picture of the pandemic's impact on suicides globally.
Methods: We identified suicide data from official public-sector sources for countries/areas-within-countries, searching websites and academic literature and contacting data custodians and authors as necessary. We sent our first data request on 22nd June 2021 and stopped collecting data on 31st October 2021. We used interrupted time series (ITS) analyses to model the association between the pandemic's emergence and total suicides and suicides by sex-, age- and sex-by-age in each country/area-within-country. We compared the observed and expected numbers of suicides in the pandemic's first nine and first 10-15 months and used meta-regression to explore sources of variation.
Findings: We sourced data from 33 countries (24 high-income, six upper-middle-income, three lower-middle-income; 25 with whole-country data, 12 with data for area(s)-within-the-country, four with both). There was no evidence of greater-than-expected numbers of suicides in the majority of countries/areas-within-countries in any analysis; more commonly, there was evidence of lower-than-expected numbers. Certain sex, age and sex-by-age groups stood out as potentially concerning, but these were not consistent across countries/areas-within-countries. In the meta-regression, different patterns were not explained by countries’ COVID-19 mortality rate, stringency of public health response, economic support level, or presence of a national suicide prevention strategy. Nor were they explained by countries’ income level, although the meta-regression only included data from high-income and upper-middle-income countries, and there were suggestions from the ITS analyses that lower-middle-income countries fared less well.
Interpretation: Although there are some countries/areas-within-countries where overall suicide numbers and numbers for certain sex- and age-based groups are greater-than-expected, these countries/areas-within-countries are in the minority. Any upward movement in suicide numbers in any place or group is concerning, and we need to remain alert to and respond to changes as the pandemic and its mental health and economic consequences continue.
