Exploring delusional themes and other symptoms in first episode psychosis: A network analysis over two timepoints.

Delusions are a defining feature of psychosis and play an important role in the conceptualization and diagnosis of psychotic disorders; however, the particular role that different delusions play in the prognosis of these disorders is not well understood. This study explored relationships between delusions and other symptoms in 674 first episode psychosis (FEP) individuals by comparing symptom networks between baseline and 12 months after intake to an early intervention service. Specifically, we (1) estimated regularized partial correlation networks at baseline and month 12, (2) identified the most central symptoms in each network, (3) identified clusters of highly connected symptoms, and (4) compared networks to examine changes in structure and connectivity.

ISWI chromatin remodeler SMARCA5 is essential for meiotic gene expression and male fertility in mammals.

Regulation of the transcriptome to promote meiosis is important for sperm development and fertility. However, how chromatin remodeling directs the transcriptome during meiosis in male germ cells is largely unknown. Here, we demonstrate that the ISWI family ATP-dependent chromatin remodeling factor SMARCA5 (SNF2H) plays a critical role in regulating meiotic prophase progression during spermatogenesis.

Consistency of Delusion Themes Across First and Subsequent Episodes of Psychosis.

Importance: Despite growing interest in the phenomenology of delusions in psychosis, at present little is known about their content and evolution over time, including whether delusion themes are consistent across episodes.

Objective: To examine the course of delusions and thematic delusion content across relapse episodes in patients presenting to an early intervention service for psychosis.

Design, Setting, And Participants: This longitudinal, observational study used clinical data systematically collected from January 2003 to March 2018 from a cohort of consenting patients with affective or nonaffective first-episode psychosis, followed up naturalistically for up to 2 years in an early intervention service for psychosis in Montréal, Quebec, Canada.

Development of an early intervention in psychosis services fidelity questionnaire.

Purpose: We describe the development of an online fidelity questionnaire for early intervention in psychosis (EIP) services, to be used in population-level research, and that can be completed using self-reports from EIP staff.

Methods: A review of key literature sources on the components of EIP services was used to identify those components eligible for inclusion in the questionnaire. A modified Delphi approach, using experts in EIP services, was used to select the most important components to include in the questionnaire.

Preliminary evaluation of a questionnaire for assessing fidelity of early intervention for psychosis services.

Purpose: Fast, easy, and cost-effective methods are needed for fidelity assessment, quality improvement initiatives, and population-based studies in Early Intervention for Psychosis (EIP) services. Having an online questionnaire assessing the fidelity of EIP services, completed by staff self-reports, and having evidence of reliability and validity, could fill that gap. We assess the reliability and validity of the Early Intervention for Psychosis Services Fidelity Questionnaire (EIPS-FQ), developed in Part I of this set of papers.

Traumatic Brain Injury and Its Association With Orbital Fracture Characteristics and Repair.

Traumatic brain injury (TBI) is common in up to 50% of patients with facial fractures. Orbital fractures account for 25% of all facial fractures. The authors sought to determine the prevalence and risk factors for TBI in patients undergoing orbital fracture repair (OFR) and assess the impact of TBI on surgical timing.

Microbubble-Enhanced Focused Ultrasound for Infiltrating Gliomas.

Infiltrating gliomas are challenging to treat, as the blood-brain barrier significantly impedes the success of therapeutic interventions. While some clinical trials for high-grade gliomas have shown promise, patient outcomes remain poor. Microbubble-enhanced focused ultrasound (MB-FUS) is a rapidly evolving technology with demonstrated safety and efficacy in opening the blood-brain barrier across various disease models, including infiltrating gliomas.

Patient- and family-reported experiences of their treating teams in early psychosis services in Chennai, India and Montreal, Canada.

Background: Cross-cultural psychosis research has mostly focused on outcomes, rather than patient and family experiences. Therefore, our aim was to examine differences in patients' and families' experiences of their treating teams in early intervention services for psychosis in Chennai, India [low- and middle-income country] and Montreal, Canada [high-income country].

Methods: Patients (165 in Chennai, 128 in Montreal) and their families (135 in Chennai, 110 in Montreal) completed Show me you care, a patient- and family-reported experience measure, after Months 3, 12, and 24 in treatment.

Inhibition of lactate dehydrogenase A by diclofenac sodium induces apoptosis in HeLa cells through activation of AMPK.

Cancer cells exhibit a unique metabolic preference for the glycolytic pathway over oxidative phosphorylation for maintaining the tumor microenvironment. Lactate dehydrogenase A (LDHA) is a key enzyme that facilitates glycolysis by converting pyruvate to lactate and has been shown to be upregulated in multiple cancers due to the hypoxic tumor microenvironment. Diclofenac (DCF), a nonsteroidal anti-inflammatory drug, has been shown to exhibit anticancer effects by interfering with the glucose metabolism pathway.

Sociodemographic and clinical correlates of hallucinations in patients entering an early intervention program for first episode psychosis.

Hallucinations are a core feature of psychosis, and their severity during the acute phase of illness is associated with a range of poor outcomes. Various clinical and sociodemographic factors may predict hallucinations and other positive psychotic symptoms in first episode psychosis (FEP). Despite this, the precise factors associated with hallucinations at first presentation to an early intervention service have not been extensively researched.

Studying the context of psychoses to improve outcomes in Ethiopia (SCOPE): Protocol paper.

Background: Global evidence on psychosis is dominated by studies conducted in Western, high-income countries. The objectives of the Study of Context Of Psychoses to improve outcomes in Ethiopia (SCOPE) are (1) to generate rigorous evidence of psychosis experience, epidemiology and impacts in Ethiopia that will illuminate aetiological understanding and (2) inform development and testing of interventions for earlier identification and improved first contact care that are scalable, inclusive of difficult-to-reach populations and optimise recovery.

Methods: The setting is sub-cities of Addis Ababa and rural districts in south-central Ethiopia covering 1.

Characterization of plant produced V antibodies against cobra venom toxins for antivenom therapy.

Cobra () venom contains many toxins including α-neurotoxin (αNTX) and phospholipase A2 (PLA2), which can cause neurodegeneration, respiratory failure, and even death. The traditional antivenom derived from animal serum faces many challenges and limitations. Heavy-chain-only antibodies (HCAb), fusing V with human IgG Fc region, offer advantages in tissue penetration, antigen binding, and extended half-life.

Longitudinal inference of multiscale markers in psychosis: from hippocampal centrality to functional outcome.

Multiscale neuroscience conceptualizes mental illness as arising from aberrant interactions across and within multiple biopsychosocial scales. We leverage this framework to propose a multiscale disease progression model of psychosis, in which hippocampal-cortical dysconnectivity precedes impairments in episodic memory and social cognition, which lead to more severe negative symptoms and lower functional outcome. As psychosis represents a heterogeneous collection of biological and behavioral alterations that evolve over time, we further predict this disease progression for a subtype of the patient sample, with other patients showing normal-range performance on all variables.
