The association between adverse childhood experiences and alterations in brain volume and cortical thickness in adults with alcohol use disorder.

Background: Previous studies have established a connection between adverse childhood experiences (ACE) and alcohol use disorder (AUD), both of which are associated with alterations in grey matter volume (GMV) and cortical thickness (CT). The current study aimed to assess the neurobiological impact of ACE specifically in the context of AUD, as well as the role of maltreatment type (i.e.

New insights into the effects of type and timing of childhood maltreatment on brain morphometry.

Childhood maltreatment (CM) is known to influence brain development. To obtain a better understanding of related brain alterations, recent research has focused on the influence of the type and timing of CM. We aimed to investigate the association between type and timing of CM and local brain volume.

Usage Behaviour and Adoption Criteria for Mobile Health Solutions in Patients with Chronic Diseases in Gastroenterology.

Introduction: Mobile Health (mHealth) applications allow for new possibilities and opportunities in patient care. Their potential throughout the whole patient journey is undisputed. However, the eventual adoption by patients depends on their acceptance of and motivation to use mHealth applications as well as their adherence.

Childhood Maltreatment and Amygdala Response to Interpersonal Threat in a Transdiagnostic Adult Sample: The Role of Trait Dissociation.

Background: Childhood maltreatment (CM) confers risk for different mental disorders as well as transdiagnostic symptoms such as dissociation. Aberrant amygdala response to interpersonal threat may link CM to transdiagnostic psychopathology and has recently been shown to depend on type and developmental timing of CM experiences. Still, most studies on CM and threat-related amygdala response employ categorical disorder-specific perspectives and fail to consider type and timing of CM exposure.

The DNA methylation landscape of the human oxytocin receptor gene (OXTR): data-driven clusters and their relation to gene expression and childhood adversity.

The oxytocin receptor gene (OXTR) is of interest when investigating the effects of early adversity on DNA methylation. However, there is heterogeneity regarding the selection of the most promising CpG sites to target for analyses. The goal of this study was to determine functionally relevant clusters of CpG sites within the OXTR CpG island in 113 mother-infant dyads, with 58 of the mothers reporting childhood maltreatment (CM).

Structural Correlates of Lifetime Voice-Hearing in Patients with Borderline Personality Disorder: A Pilot Study.

Introduction: Auditory verbal hallucinations (AVH) are transdiagnostic phenomena that can occur in several mental disorders, including borderline personality disorder (BPD). Despite the transdiagnostic relevance of these symptoms, very little is known about neural signatures of AVH in BPD.

Methods: We used structural magnetic resonance imaging to investigate multiple markers of brain morphology in BPD patients presenting with a lifetime history of AVH (AVH, n = 6) versus BPD patients without AVH (nAVH, n = 10) and healthy controls (HC, n = 12).

Neurostructural associations with traumatic experiences during child- and adulthood.

Adverse experiences can lead to severe mental health problems, such as posttraumatic stress disorder (PTSD), throughout the lifespan. In individuals with PTSD, both global and local brain volume reductions have been reported-especially in the amygdala and hippocampus-while the literature on childhood maltreatment suggests a strong dependency on the timing of adverse events. In the present study, we pooled data from two studies to contrast the effects of reported trauma exposure during neurodevelopmentally sensitive periods in early life with trauma exposure during adulthood.

Open and reproducible science practices in psychoneuroendocrinology: Opportunities to foster scientific progress.

This perspective article was written by invitation of the editors in chief as a summary and extension of the symposium entitled which was held at the virtual meeting of the 2021. It highlights the opportunities presented by the application of open and reproducible scientific practices in psychoneuroendocrinology (PNE), an interdisciplinary field at the intersection of psychology, endocrinology, immunology, neurology, and psychiatry. It conveys an introduction to the topics preregistration, registered reports, quantifying the impact of equally-well justifiable analysis decisions, and open data and scripts, while emphasizing 'selfish' reasons to adopt such practices as individual researcher.

Survey on Open Science Practices in Functional Neuroimaging.

Replicability and reproducibility of scientific findings is paramount for sustainable progress in neuroscience. Preregistration of the hypotheses and methods of an empirical study before analysis, the sharing of primary research data, and compliance with data standards such as the Brain Imaging Data Structure (BIDS), are considered effective practices to secure progress and to substantiate quality of research. We investigated the current level of adoption of open science practices in neuroimaging and the difficulties that prevent researchers from using them.

Psychological structure and neuroendocrine patterns of daily stress appraisals.

Threat and challenge are two fundamental appraisal concepts of psychological stress theories, determined by the mismatch between demands and resources. Previous research has predominantly investigated the neuroendocrine correlates of stress appraisal in laboratory contexts during acute demanding situations. We tested whether the psychoneuroendocrinology of stress appraisals can also be investigated in naturalistic trans-contextual everyday life settings.

Emotion dysregulation in borderline personality disorder: A fronto-limbic imbalance?

Borderline personality disorder is most consistently characterized as a disorder of the experience and regulation of emotions. Neuropathological models have predominantly explained these clinical traits with an imbalance between prefrontal regulatory and limbic emotion generating structures. Here, we review the current evidential state of the fronto-limbic imbalance hypothesis of borderline personality disorder, based on task-related functional magnetic resonance imaging research.

Differential Effects of Early Adversity and Posttraumatic Stress Disorder on Amygdala Reactivity: The Role of Developmental Timing.

Background: Posttraumatic stress disorder (PTSD) is associated with altered processing of threat-related stimuli. Neurobiological models implicate right amygdala hyperreactivity in these alterations, but this potential biomarker also has been observed in individuals exposed to adverse childhood experiences (ACEs) (i.e.

Highs and lows: Genetic susceptibility to daily events.

Why people differ in their susceptibility to external events is essential to our understanding of personality, human development, and mental disorders. Genes explain a substantial portion of these differences. Specifically, genes influencing the serotonin system are hypothesized to be differential susceptibility factors, determining a person's reactivity to both positive and negative environments.

Oxytocin and the stress buffering effect of social company: a genetic study in daily life.

Social relationships are a crucial determinant of both mental and physical health. This effect is partly due to social buffering of stress. Animal studies suggest that social buffering is mediated via the oxytocin system, while studies in humans are sparse and limited by the low ecological validity of laboratory settings.
