Effects of Adapted Physical Activity on White Matter Integrity in Patients with Schizophrenia.

Schizophrenia is associated with changes in white matter (WM) integrity and with reduced life expectancy, in part because of the cardiometabolic side effects of antipsychotics. Physical activity (PA) has emerged as a candidate lifestyle intervention that is safe and effective. The study aimed to assess how an adapted PA program delivered remotely by web (e-APA) improved WM integrity in patients with schizophrenia (SZPs) and healthy controls (HCs) and to evaluate associations among WM integrity, cardiorespiratory fitness, and symptom severity.

Does the Paraphilia Scale Work for Everyone? Confirmatory Factor Analysis and Measurement Invariance Across Gender and Sexual Orientation Groups.

We conducted three studies to examine the factor structure and measurement invariance of the Paraphilia Scale, a measure of paraphilic interests used in multiple studies. In the first study, we conducted a confirmatory factor analysis (CFA) testing different a priori models with a community sample of 1,040 adults previously reported by Seto et al. (2021), and found support for a hierarchical four-factor model: An involving coercion or physical pain (biastophilia, sexual sadism, masochism), (pedophilia, hebephilia), (voyeurism, exhibitionism, and frotteurism), and (object fetishism, transvestic fetishism, urophilia-coprophilia).

Effects of web-based adapted physical activity on hippocampal plasticity, cardiorespiratory fitness, symptoms, and cardiometabolic markers in patients with schizophrenia: a randomized, controlled study.

Among the lifestyle interventions, the physical activity (PA) has emerged as an adjuvant non-pharmacological treatment improving mental and physical health in patients with schizophrenia (SZPs) and increasing the hippocampus (HCP) volume. Previously investigated PA programs have been face-to-face, and not necessary adapted to patients' physiological fitness. We propose an innovative 16-week adapted PA program delivered by real-time videoconferencing (e-APA), allowing SZPs to interact with a coach and to manage their physical condition.

Studying Muscle Transcriptional Dynamics at Single-molecule Scales in Drosophila.

Skeletal muscles are large syncytia made up of many bundled myofibers that produce forces and enable body motion. Drosophila is a classical model to study muscle biology. The combination of both Drosophila genetics and advanced omics approaches led to the identification of key conserved molecules that regulate muscle morphogenesis and regeneration.

Measurement invariance of the Youth Self-Report across youth who have committed sexual and nonsexual offenses.

Justice-involved youth experience high rates of mental health problems that require proper screening and assessment in order to effectively intervene. The Youth Self-Report (YSR) is a general psychopathology rating scale that measures several dimensions of psychopathology and is commonly used in clinical assessments, including with justice-involved youth. Yet, the underlying factor structure of the YSR has not been examined specifically in a sample of justice-involved youth.

Tau Transfer via Extracellular Vesicles Disturbs the Astrocytic Mitochondrial System.

Tauopathies are neurodegenerative disorders involving the accumulation of tau isoforms in cell subpopulations such as astrocytes. The origins of the 3R and 4R isoforms of tau that accumulate in astrocytes remain unclear. Extracellular vesicles (EVs) were isolated from primary neurons overexpressing 1N3R or 1N4R tau or from human brain extracts (progressive supranuclear palsy or Pick disease patients or controls) and characterized (electron microscopy, nanoparticle tracking analysis (NTA), proteomics).

How to Successfully Generate an Alternative Approach to a Thorough QT Study: GLPG1972 as an Example.

During development of a drug, the requirement of evaluating the proarrhythmic risk and delayed repolarization needs to be fulfilled. Would it be possible to create an alternative to a thorough QT (TQT) study or is there a need to perform a dedicated TQT study? How is an alternative approach generated, what information is available, and which instructions are considered missing today to generate such an approach? This tutorial describes the considerations and path followed to create an early and feasible alternative to a TQT study using experience-based insights from a successful application to the US Food and Drug Administration for GLPG1972, an ADAMTS-5 inhibitor, and discusses the approach used in light of the current guidelines and literature.

Sexual Sadism Disorder and Coercive Paraphilic Disorder: A Scoping Review.

Background: Valid and reliable diagnostic criteria are essential in forensic psychiatry and sexual medicine due to the severe implications of potential misdiagnoses. One challenge in this field is the poor operationalization of sexual sadism disorder (SSD) and coercive paraphilic disorder (CP+) definitions.

Aim: The aim of this scoping literature review is to provide a comprehensive overview of the key conceptual differences between SSD and CP+, as well as consider pragmatic and clinically useful approaches to their diagnostic formulation.

[Extracellular vesicles in the central nervous system].

Extracellular Vesicles (EVs) are released by a wide diversity of cells. They contain proteins, RNAs and lipids that will be exchanged between these cells. They represent therefore a major form of intercellular communication in both physiological and pathological conditions.

Safety, Pharmacokinetics, and Pharmacodynamics of the ADAMTS-5 Inhibitor GLPG1972/S201086 in Healthy Volunteers and Participants With Osteoarthritis of the Knee or Hip.
