The effect of fampridine on working memory: a randomized controlled trial based on a genome-guided repurposing approach.

Working memory (WM), a key component of cognitive functions, is often impaired in psychiatric disorders such as schizophrenia. Through a genome-guided drug repurposing approach, we identified fampridine, a potassium channel blocker used to improve walking in multiple sclerosis, as a candidate for modulating WM. In a subsequent double-blind, randomized, placebo-controlled, crossover trial in 43 healthy young adults (ClinicalTrials.

Silexan in anxiety, depression, and related disorders: pharmacological background and clinical data.

We present a narrative review of clinical trials investigating the anxiolytic and antidepressant effects of silexan, an active substance derived from lavender oil and summarize nonclinical findings from pharmacological studies supporting its therapeutic use. Six studies investigated the efficacy of the lavender oil in patients with subthreshold and generalized anxiety disorders as well as in mixed anxiety and depressive disorder (MADD). Furthermore, we present data indicating that silexan may influence sleep quality as well as anxiety or depressive disorders in individuals with post-COVID-19.

Gelsemium low doses protect against serum deprivation-induced stress on mitochondria in neuronal cells.

Ethnopharmacological Relevance: Gelsemium dynamized dilutions (GDD) are known as a remedy for a wide range of behavioral and psychological symptoms of depression and anxiety at ultra-low doses, yet the underlying mechanisms of the mode of action of G. sempervirens itself are not well understood.

Aim Of The Study: The present study was designed to examine the neuroprotective effects of Gelsemium preparations in counteracting stress-related mitochondrial dysfunctions in neuronal cells.

Neurocognitive performance of patients undergoing intravenous versus oral opioid agonist treatment: a prospective multicenter study on three-month treatment effects.

Introduction: The first-line treatment for opioid dependence is opioid agonist treatment (OAT) with oral opioids. However, in some cases, treatment with intravenous diacetylmorphine (IV-DAM) is indicated. Research on neurocognitive impairments and treatment effects of OAT - particularly with IV-DAM - on neurocognitive functioning, is scarce.

Polygenic susceptibility for multiple sclerosis is associated with working memory in low-performing young adults.

Background: Multiple sclerosis (MS) is a complex disease with substantial heritability estimates. Besides typical clinical manifestations such as motor and sensory deficits, MS is characterized by structural and functional brain abnormalities, and by cognitive impairment such as decreased working memory (WM) performance.

Objectives: We investigated the possible link between the polygenic risk for MS and WM performance in healthy adults (18-35 years).

The mitochondrial translocator protein (TSPO) in Alzheimer's disease: Therapeutic and immunomodulatory functions.

The translocator protein (TSPO) has been widely investigated as a PET-imaging biomarker of neuroinflammation and, more recently, as a therapeutic target for the treatment of neurodegenerative disease. TSPO ligands have been shown to exert neuroprotective effects in vivo and in vitro models of Alzheimer's disease (AD), by reducing toxic beta amyloid peptides, and attenuating brain atrophy. Recent transcriptomic and proteomic analyses, and the generation of TSPO-KO mice, have enabled new insights into the mechanistic function of TSPO in AD.

Tweaking synaptic plasticity: Deciphering the role of WWC1 in memory opens new therapeutic horizons.

WWC1 is a scaffolding protein in the evolutionarily conserved Hippo signaling network and is genetically linked to human memory and synaptic plasticity. In the archives of , Stepan demonstrate the translational potential of modulating WWC1 through pharmacological inhibition of Hippo-pathway kinases to enhance cognition.

Prolonged diacetylmorphine take-home during the COVID-19 pandemic-Results of a retrospective cohort study.

Background And Aims: Legal regulations for dispensing in Swiss heroin-assisted treatment were relaxed during the COVID-19 pandemic, allowing prolonged take-home of up to 7 days instead of two to reduce patient contact and the risk of infection. Our study aimed to measure the consequences of this new practice.

Design, Setting And Participants: This was a retrospective cohort study set in Switzerland's largest outpatient centre for opioid agonist therapy.

Child and family characteristics in multisystemic therapy for child abuse and neglect (MST-CAN): Are there associations with treatment outcome?

Evidence-based indication for targeted interventions is a central approach in the field of child welfare and psychotherapy. This study explored the characteristics of children and families referred to Multisystemic Therapy for Child Abuse and Neglect (MST-CAN) in Switzerland and their associations with treatment outcomes. We sought to identify subgroups of children and families referred to MST-CAN and understand their specific needs and alignment with the program.

Enhanced conductive body heat loss during sleep increases slow-wave sleep and calms the heart.

Substantial evidence suggests that the circadian decline of core body temperature (CBT) triggers the initiation of human sleep, with CBT continuing to decrease during sleep. Although the connection between habitual sleep and CBT patterns is established, the impact of external body cooling on sleep remains poorly understood. The main aim of the present study is to show whether a decline in body temperatures during sleep can be related to an increase in slow wave sleep (N3).

Translocator protein (TSPO) ligands attenuate mitophagy deficits in the SH-SY5Y cellular model of Alzheimer's disease via the autophagy adaptor P62.

Mitochondrial dysfunction has been widely implicated in the pathogenesis of Alzheimer's disease (AD), with accumulation of damaged and dysfunctional mitochondria occurring early in the disease. Mitophagy, which governs mitochondrial turnover and quality control, is impaired in the AD brain, and strategies aimed at enhancing mitophagy have been identified as promising therapeutic targets. The translocator protein (TSPO) is an outer mitochondrial membrane protein that is upregulated in AD, and ligands targeting TSPO have been shown to exert neuroprotective effects in mouse models of AD.

"Alone Again, Naturally": Mental Health Problems, Level of Personality Functioning, Social Withdrawal and Loneliness in Adolescents Admitted as Acute Inpatients in the Aftermath of the COVID-19 Pandemic.

(1) Background: Adolescents admitted as acute inpatients belong to a particularly psychosocially vulnerable population. This study aimed to examine the clinical characteristics of an affected population in Germany using a theory-based approach. (2) Methods: We assessed the mental health problems, levels of personality functioning, and the severity of social withdrawal and loneliness in = 62 adolescents admitted to an acute psychiatric inpatient unit.

Interplay between stress, sleep, and BDNF in a high-risk sample of young adults.

Children in institutional care have a high risk to experience childhood adversities (CAs), with consequences for physical and mental well-being. The long-term effects of CAs on the brain, including consequences for neuronal plasticity and sleep, are poorly understood. This study examined the interplay between stress (including CAs), sleep, and brain-derived neurotrophic factor (BDNF), a prominent marker for neuronal plasticity.

Sex-dependent differences in connectivity patterns are related to episodic memory recall.

Previous studies have shown that females typically outperform males on episodic memory tasks. In this study, we investigated if (1) there are differences between males and females in their connectome characteristics, (2) if these connectivity patterns are associated with memory performance, and (3) if these brain connectome characteristics contribute to the differences in episodic memory performance between sexes. In a sample of 655 healthy young subjects (n = 391 females; n = 264 males), we derived brain network characteristics from diffusion-weighted imaging (DWI) data using models of crossing fibers within each voxel of the brain and probabilistic tractography (graph strength, shortest path length, global efficiency, and weighted transitivity).

Operationalized Psychodynamic Diagnostic of Adolescents in Light of the New ICD-11 Model of Personality Functioning: Personality Structure, Psychodynamic Conflicts, and Mental Health Problems.

The International Classification of Diseases and Related Health Problems, 11th Revision introduced a fully dimensional approach to personality disorders which conceptionally converges with the long-standing psychodynamic understanding of psychopathology through underlying intra- and interpersonal impairments. In this study, the diagnostic contributions of the two psychodynamic concepts of personality structure and psychodynamic conflicts were investigated through the comparison of self-report data of 189 adolescents with mental health problems and 321 mentally healthy controls. The study results reveal that adolescents with mental health problems show significantly higher impairments in all four domains of personality structure and significantly higher levels of several psychodynamic conflicts.

ER-mitochondria contacts and cholesterol metabolism are disrupted by disease-associated tau protein.

Abnormal tau protein impairs mitochondrial function, including transport, dynamics, and bioenergetics. Mitochondria interact with the endoplasmic reticulum (ER) via mitochondria-associated ER membranes (MAMs), which coordinate and modulate many cellular functions, including mitochondrial cholesterol metabolism. Here, we show that abnormal tau loosens the association between the ER and mitochondria in vivo and in vitro.

With great power comes great vulnerability: an ethical analysis of psychedelics' therapeutic mechanisms proposed by the REBUS hypothesis.

Psychedelics are experiencing a renaissance in mental healthcare. In recent years, more and more early phase trials on psychedelic-assisted therapy have been conducted, with promising results overall. However, ethical analyses of this rediscovered form of treatment remain rare.

Effects of cannabis regulation in Switzerland: Study protocol of a randomized controlled trial.

Background: Cannabis is the most widely used illicit substance. Various countries have legalized cannabis for recreational use. Evidence on the health effects of cannabis regulation remains unclear and is mainly based on observational studies.

Spermidine Rescues Bioenergetic and Mitophagy Deficits Induced by Disease-Associated Tau Protein.

Abnormal tau build-up is a hallmark of Alzheimer's disease (AD) and more than 20 other serious neurodegenerative diseases. Mitochondria are paramount organelles playing a predominant role in cellular bioenergetics, namely by providing the main source of cellular energy via adenosine triphosphate generation. Abnormal tau impairs almost every aspect of mitochondrial function, from mitochondrial respiration to mitophagy.

Epigenetics of traumatic stress: The association of NR3C1 methylation and posttraumatic stress disorder symptom changes in response to narrative exposure therapy.

Epigenetic processes allow plasticity in gene regulation in response to significant environmental events. Accumulating evidence suggests that effective psychotherapy is accompanied by epigenetic changes, rendering DNA methylation a potential biomarker of therapy success. Due to the central role of glucocorticoid dynamics in stress regulation and the alteration of aversive memories, glucocorticoid receptors are likely involved in the molecular processes that are required to successfully treat Posttraumatic Stress Disorder (PTSD).

Mitochondria Transfer in Brain Injury and Disease.

Intercellular mitochondria transfer is a novel form of cell signalling in which whole mitochondria are transferred between cells in order to enhance cellular functions or aid in the degradation of dysfunctional mitochondria. Recent studies have observed intercellular mitochondria transfer between glia and neurons in the brain, and mitochondrial transfer has emerged as a key neuroprotective mechanism in a range of neurological conditions. In particular, artificial mitochondria transfer has sparked widespread interest as a potential therapeutic strategy for brain disorders.

Psychometric assessment of the German version of the Questionnaire about the Process of Recovery.

Personal recovery is important for mental health services and service users; moreover, valid and reliable assessment instruments are necessary for measuring personal recovery. Therefore, this study aimed to evaluate the unidimensional factor structure of the German version of the Questionnaire about the Process of Recovery. The study was conducted using a cross-sectional design with a convenience sample.

Is helping you helping me? The assessment of helping others using event sampling methodology in a clinical and a non-clinical sample.

Individuals diagnosed with major depressive disorder (MDD) and social phobia (SP) have difficulties in social interactions. It is unknown, however, whether such difficulties prevent them from helping others, thereby depriving them of the natural benefits of helping, such as receiving gratitude. Using event sampling methodology (ESM), individuals (MDD, n = 118; SP, n = 47; and control group, n = 119) responded to questions about the frequency of helping, in total at 5333 time points, and their well-being.
