  • Formal thought disorder (FTD) is a key symptom of schizophrenia, but its exact neurobiological causes and correlation with brain volume loss are still unclear, which this study seeks to address using a large cohort of patients and controls.
  • The research focuses on differentiating between positive, negative, and total formal thought disorder while investigating brain structural changes and their cellular bases using virtual histology tools.
  • Findings reveal distinct neural networks for positive and negative FTD, with negative FTD showing preserved orbitofrontal thickness and both FTD types linked to unique cellular fingerprint patterns, advancing our understanding of the disorder.

Bipolar disorder (BD) is a heritable mental illness with complex etiology. While the largest published genome-wide association study identified 64 BD risk loci, the causal SNPs and genes within these loci remain unknown. We applied a suite of statistical and functional fine-mapping methods to these loci, and prioritized 17 likely causal SNPs for BD.

Article Synopsis
  • Schizophrenia is characterized by significant changes in brain structure, but it's not clear if these changes relate to the brain's network organization.
  • Researchers analyzed MRI scans from nearly 2,500 people with schizophrenia alongside healthy controls to see how structural changes connect to brain networks.
  • The study found that certain regions in the brain that are crucial for connectivity are more affected in schizophrenia, indicating a link between brain network vulnerability and the disease's impact, with some similarities to bipolar disorder but not major depressive disorder.

Importance: There are currently 55 million adults living with declining functional cognition-altered perception, thoughts, mood, or behavior-as the result of Alzheimer's disease (AD) and related neurocognitive disorders (NCDs). These changes affect functional performance and meaningful engagement in occupations. Given the growth in demand for services, occupational therapy practitioners benefit from consolidated evidence of effective interventions to support adults living with AD and related NCDs and their care partners.

The relationship between childhood maltreatment and subsequent offending/victimization is well established. However, the magnitude of this relationship for different levels of child protection services (CPS) involvement is poorly understood, due to measurement issues, lack of longitudinal data, and reliance on reports of substantiated maltreatment, which can underestimate the impact of maltreatment. This study examined associations between CPS involvement during childhood (ages 0 to <11 years) and police services contact (as a victim and/or a person of interest) for criminal incidents in early adolescence (11 to ~14 years), differentiated according to levels of CPS involvement (i.

While RNA expression appears to be altered in several brain disorders, the constraints of postmortem analysis make it impractical for well-powered population studies and biomarker development. Given that the unique molecular composition of neurons are reflected in their extracellular vesicles (EVs), we hypothesized that the fractionation of neuron derived EVs provides an opportunity to specifically profile their encapsulated contents noninvasively from blood. To investigate this hypothesis, we determined miRNA expression in microtubule associated protein 1B (MAP1B)-enriched serum EVs derived from neurons from a large cohort of individuals with schizophrenia and nonpsychiatric comparison participants.

Leucine-rich repeat and immunoglobulin domain-containing protein (Lingo-1) plays a vital role in a large number of neuronal processes underlying learning and memory, which are known to be disrupted in schizophrenia. However, Lingo-1 has never been examined in the context of schizophrenia. The genetic association of a single-nucleotide polymorphism (SNP, rs3144) and methylation (CpG sites) in the 3'-UTR region was examined, with the testing of cognitive dysfunction and white matter (WM) integrity in a schizophrenia case-control cohort (n = 268/group).

Assessment practices in Higher Education remain beholden to the twin pillars of neoliberal economic orthodoxy and White supremacy. The former has given rise to the modularization and commodification of education, wherein student performance is measured according to narrow and often meaningless metrics that foster and maintain ineffective assessment mechanisms. The latter imbues those metrics with a deference to, and valorization of, "Whiteness" as a marker of success, and this manifests in persistent awarding gaps across the sector.

Article Synopsis
  • Schizotypy, which indicates a person's vulnerability to psychosis, is linked to both childhood trauma and structural brain changes.
  • A study involving 1182 healthy adults found that interactions between schizotypy levels and childhood trauma exposure affect brain morphology, specifically in regions related to cognitive processing.
  • Results suggest that individuals with high levels of both schizotypy and childhood trauma show significant variations in brain regions important for cognition, indicating that trauma may intensify the effects of schizotypy on brain structure.

Introduction: Treatment of coronavirus disease 2019 (COVID-19) patients may require antithrombotic and/or anti-inflammatory medications. We hypothesized that individualized anticoagulant (AC) management, based on diagnosis of coagulopathy using thromboelastography with platelet mapping (TEG-PM), would decrease the frequency of pulmonary failure (PF) requiring mechanical ventilation (MV), mitigate thrombotic and hemorrhagic events, and, in-turn, reduce mortality.

Methods: Hospital-admitted COVID-19 patients, age 18 or older, with escalating oxygen requirements were included.
