Self-stigma in alcohol dependence scale: development and validity of the short form.

Background: Self-stigma is associated with low self-esteem, high shame and reduced drinking-refusal self-efficacy in people with alcohol use disorder (AUD). The Self-Stigma in Alcohol-Dependence Scale-Short Form (SSAD-SF) was designed to enable a brief, but valid assessment of AUD self-stigma.

Methods: We reduced the 64-item SSAD, originally derived from 16 stereotypes towards people with AUD, by removing the most offensive items based on perspectives of people with lived experience.

Public attitudes towards protecting the human rights of people with mental illness: a scoping review and data from a population trend study in Germany.

The human rights of people with mental illness are constantly threatened. We conduct a scoping review showing how public attitudes towards protecting human rights have so far been examined and providing an overview of our present knowledge of these attitudes, and present novel findings from a trend study in Germany over nine years, reporting attitudes elicited in 2020 and examining whether these attitudes have changed since 2011. Few studies address attitudes towards human rights explicitly, but several studies contain single items on either first generation human rights, mainly concerning involuntary admission, or civil liberties like the right to vote, or second generation human rights, mainly with regard to funding for healthcare, but also for example regarding career choice.

Mammillary body and hypothalamic volumes in mood disorders.

We have previously reported an in vivo enlargement of the left hypothalamus in mood disorders using 7 T magnetic resonance imaging. The aim of this follow-up study was to find out whether the hypothalamic volume difference may be located in the mammillary bodies (MB) rather than being widespread across the hypothalamus. We developed and evaluated a detailed segmentation algorithm that allowed a reliable segmentation of the MBs, and applied it to 20 unmedicated (MDDu) and 20 medicated patients with major depressive disorder, 21 medicated patients with bipolar disorder, and 23 controls.

Hypothalamic volume in pedophilia with or without child sexual offense.

The hypothalamus regulates sexual behavior and is simultaneously associated with aggression and violence. Consequently, this brain region is relevant in research of pedophilia and child sexual offenses (CSO). The distinction between these two phenomena is of great importance and was the object of consideration of this study.

Changes in mental illness stigma over 30 years - Improvement, persistence, or deterioration?

Background: Large efforts have been made to erase the stigma of mental illness, but it is unclear whether they have succeeded on a population level. We examine how attitudes toward people with depression or schizophrenia have evolved in Germany since 1990, and whether there are different developments for both disorders.

Methods: Using data from the three decades, four wave repeated cross-sectional representative population study in the "old" (western) states in Germany with surveys in 1990 ( = 2,044), 2001 ( = 4,005), 2011 ( = 1,984), and 2020 ( = 2,449), we calculate time-trends for social distance and emotional reactions toward someone with major depression or acute schizophrenia.

Changes in continuum beliefs for depression and schizophrenia in the general population 2011-2020: a widening gap.

Purpose: The public discourse about mental health and mental illness seems to have become more open over the last decade, giving rise to the hope that symptoms of mental illness have become more relatable. We examine whether continuum beliefs regarding schizophrenia and depression have increased on a population level over a period of 9 years, and whether notions of unfamiliarity and incomprehensibility have decreased.

Methods: In 2011 (n = 2455) and 2020 (n = 3042), two methodologically identical cross-sectional population surveys were conducted in Germany.

Stigma as a barrier to addressing childhood trauma in conversation with trauma survivors: A study in the general population.

Victims of childhood trauma report shame and anticipation of stigma, leading to non-disclosure and avoidance of help. Stigma is potentially aggravating the mental health consequences of childhood trauma. So far there is no comprehensive study examining stigma toward adult survivors of various forms of childhood trauma, and it is unclear whether stigma interferes with reaching out to affected individuals.

Continuum beliefs and mental illness stigma: a systematic review and meta-analysis of correlation and intervention studies.

Background: Promulgating a continuum model of mental health and mental illness has been proposed as a way to reduce stigma by decreasing notions of differentness. This systematic review and meta-analysis examines whether continuum beliefs are associated with lower stigma, and whether continuum interventions reduce stigma.

Methods: Following a pre-defined protocol (PROSPERO: CRD42019123606), we searched three electronic databases (PubMed, Web of Science, and PsycINFO) yielding 6726 studies.

A semi-automated algorithm for hypothalamus volumetry in 3 Tesla magnetic resonance images.

The hypothalamus, a small diencephalic gray matter structure, is part of the limbic system. Volumetric changes of this structure occur in psychiatric diseases, therefore there is increasing interest in precise volumetry. Based on our detailed volumetry algorithm for 7 Tesla magnetic resonance imaging (MRI), we developed a method for 3 Tesla MRI, adopting anatomical landmarks and work in triplanar view.

Pattern recognition receptors mediate pro-inflammatory effects of extracellular mitochondrial transcription factor A (TFAM).

Neuroinflammation is a common pathogenic mechanism for a number of neurodegenerative disorders including Alzheimer's and Parkinson's diseases. Microglia, the immune cells of the brain, contribute to the onset and progression of the neuroinflammation observed in these diseases. Microglia become activated and initiate an inflammatory response by interacting with a diverse set of molecules, including the group of endogenous proteins released upon cell damage, termed damage-associated molecular patterns (DAMPs).

Intensity standardisation of 7T MR images for intensity-based segmentation of the human hypothalamus.

The high spatial resolution of 7T MRI enables us to identify subtle volume changes in brain structures, providing potential biomarkers of mental disorders. Most volumetric approaches require that similar intensity values represent similar tissue types across different persons. By applying colour-coding to T1-weighted MP2RAGE images, we found that the high measurement accuracy achieved by high-resolution imaging may be compromised by inter-individual variations in the image intensity.

Elucidating the link between the modifiable risk factors of Alzheimer's disease and neuroinflammation.

Increased worldwide longevity through medical interventions, although beneficial, has allowed the age-related Alzheimer's disease (AD) to become an epidemic of the 21st century. AD pathology involves adverse activation of microglia, the immune cells of the brain and resulting chronic neuroinflammation. Certain diets, physical inactivity and Type 2 diabetes mellitus have been identified as the risk factors for developing AD, which may increase the risk of AD by neuroimmune mechanisms primarily through the overactivation of microglia.

Habenula volume increases with disease severity in unmedicated major depressive disorder as revealed by 7T MRI.

The habenula is a paired epithalamic structure involved in the pathogenesis of major depressive disorder (MDD). Evidence comes from its impact on the regulation of serotonergic and dopaminergic neurons, the role in emotional processing and studies on animal models of depression. The present study investigated habenula volumes in 20 unmedicated and 20 medicated MDD patients and 20 healthy controls for the first time by applying a triplanar segmentation algorithm on 7 Tesla magnetic resonance (MR) whole-brain T1 maps.

A new look at auranofin, dextromethorphan and rosiglitazone for reduction of glia-mediated inflammation in neurodegenerative diseases.

Neurodegenerative disorders including Alzheimer's disease are characterized by chronic inflammation in the central nervous system. The two main glial types involved in inflammatory reactions are microglia and astrocytes. While these cells normally protect neurons by providing nutrients and growth factors, disease specific stimuli can induce glial secretion of neurotoxins.

Microparticles: a new perspective in central nervous system disorders.

Microparticles (MPs) are a heterogeneous population of small cell-derived vesicles, ranging in size from 0.1 to 1  μ m. They contain a variety of bioactive molecules, including proteins, biolipids, and nucleic acids, which can be transferred between cells without direct cell-to-cell contact.

Mitochondrial transcription factor A (Tfam) is a pro-inflammatory extracellular signaling molecule recognized by brain microglia.

Microglia represent mononuclear phagocytes in the brain and perform immune surveillance, recognizing a number of signaling molecules released from surrounding cells in both healthy and pathological situations. The microglia interact with several damage-associated molecular pattern molecules (DAMPs) and recent data indicate that mitochondrial transcription factor A (Tfam) could act as a specific DAMP in peripheral tissues. This study tested the hypothesis that extracellular Tfam induces pro-inflammatory and cytotoxic responses of the microglia.

Development and evaluation of an algorithm for the computer-assisted segmentation of the human hypothalamus on 7-Tesla magnetic resonance images.

Post mortem studies have shown volume changes of the hypothalamus in psychiatric patients. With 7T magnetic resonance imaging this effect can now be investigated in vivo in detail. To benefit from the sub-millimeter resolution requires an improved segmentation procedure.

Diffusion imaging-based subdivision of the human hypothalamus: a magnetic resonance study with clinical implications.

The hypothalamus and its subdivisions are involved in many neuropsychiatric conditions such as affective disorders, schizophrenia, or narcolepsy, but parcellations of hypothalamic subnuclei have hitherto been feasible only with histological techniques in postmortem brains. In an attempt to map subdivisions of the hypothalamus in vivo, we analyzed the directionality information from high-resolution diffusion-weighted magnetic resonance images of healthy volunteers. We acquired T1-weighted and diffusion-weighted scans in ten healthy subjects at 3 T.

Structural studies of the hypothalamus and its nuclei in mood disorders.

A large body of evidence indicates that the hypothalamus is involved in pathogenetic mechanisms of mood disorders. It has been suggested that functional abnormalities of the hypothalamus are associated with structural hypothalamic changes. Structural neuroimaging allows in vivo investigation of the hypothalamus that may shed light on the underlying pathogenetic mechanisms of unipolar and bipolar disorder.

Fever in the test tube--towards a human(e) pyrogen test.

The human whole blood IL-1 test exploits the reaction of monocytes/macrophages for the detection of pyrogens: human whole blood taken from healthy volunteers is incubated in the presence of the test sample in any form, be it a solution, a powder or even solid material. Pyrogenic contaminations initiate the release of the "endogenous pyrogen" Interleukin-1beta determined by ELISA after incubation. In order to understand any differences between the pyrogenic activity in this test and the existing live rabbit test (species differences versus aberrant response of the particular blood sample), the rabbit whole blood test was developed.
