Clinical Utility and Performance of the Traditional Chinese Version of the 4-As Test for Delirium Due to Traumatic Brain Injury.

Background: Delirium is a common symptom following a traumatic brain injury (TBI) that is often overlooked by healthcare professionals. Early detection of post-traumatic delirium is crucial to improving patient outcomes and quality of life. The four As Test (4AT: alertness, attention, abbreviated mental test-4, and acute mental changes) is a brief and rapid tool for delirium assessment with acceptable reliability and validity.

Social jetlag and sleep habits in children and adolescents: Associations with autonomy (bedtime setting and electronics curfew) and electronic media use before sleep.

For young people attending school, social jetlag (SJL) refers to discrepancy in sleep/wake timing between school days and weekends. This study investigated SJL in school-aged children and adolescents in England and whether this is associated with age, gender, and sleep habits including bedtimes and electronic media use. Students (school y 5-13; typical age 9-18 y) completed the 2021 OxWell Student Survey.

Reduced White Matter Damage and Lower Neuroinflammatory Potential of Microglia and Macrophages in Hri/Eif2ak1 Mice After Contusive Spinal Cord Injury.

Cellular stressors inhibit general protein synthesis while upregulating stress response transcripts and/or proteins. Phosphorylation of the translation factor eIF2α by one of the several stress-activated kinases is a trigger for such signaling, known as the integrated stress response (ISR). The ISR regulates cell survival and function under stress.

Prenatal Stress and Maternal Role in Neurodevelopment.

This review summarizes recent findings on stress-related programming of brain development , with an emphasis on situating findings within the mothers' broader psychosocial experiences. Meta-analyses of observational studies on prenatal stress exposure indicate the direction and size of effects on child neurodevelopment are heterogeneous across studies. Inspired by lifespan and topological frameworks of adversity, we conceptualize individual variation in mothers' lived experience during and prior to pregnancy as a key determinant of these heterogeneous effects across populations.

TClC effectively suppresses the growth and metastasis of NSCLC via polypharmacology.

Despite significant advances in targeted therapies and immunotherapies, non-small cell lung cancer (NSCLC) continues to present a global health challenge, with a modest five-year survival rate of 28 %, largely due to the emergence of treatment-resistant and metastatic tumors. In response, we synthesized a novel bioactive compound, ethyl 6-chlorocoumarin-3-carboxylyl L-theanine (TClC), which significantly inhibited NSCLC growth, epithelial mesenchymal transition (EMT), migration, and invasion and tumor growth and metastasis without inducing toxicity. TClC disrupts autocrine loops that promote tumor progression, particularly in stem-like CD133-positive NSCLC (CD133+ LC) cells, which are pivotal in tumor metastasis.

Predictive modeling and interpretative analysis of risks of instability in patients with Myasthenia Gravis requiring intensive care unit admission.

Objective: Myasthenia gravis (MG), a low-prevalence autoimmune disorder characterized by clinical heterogeneity and unpredictable disease fluctuations, presents significant risks of acute exacerbations requiring intensive care. These crises contribute substantially to patient morbidity and mortality. This study aimed to develop and validate machine-learning models for predicting intensive care unit (ICU) admission risk among patients with MG-related disease instability.

Assessment of social isolation and changes in Parkinson's disease symptoms during the COVID-19 pandemic: A longitudinal study.

Background: COVID-19-related social restrictions provided an opportunity to evaluate the impact of social isolation on Parkinson's disease.

Objective: This study aimed to explore changes in social isolation and their associations with PD symptoms using the Lubben Social Network Scale-Revised (LSNS-R).

Methods: Data from 80 participants of the Early Parkinson's Disease Longitudinal Singapore cohort were collected from April 2019 to April 2023, covering the periods before and after the imposition of COVID-19 restrictions.

Acceleration of spontaneous visual recovery by voluntary physical exercise in adolescent amblyopic rats.

Abnormal visual experience during development resulting from an imbalance in the activity of the two eyes can lead to permanent severe visual deficits, a pathology called amblyopia (lazy eye). While this condition is extremely difficult to treat in adults, current interventions can elicit significant amounts of visual recovery when performed in juveniles before the end of the critical period, even if the achievable results can be unsatisfactory due to the progressive decline in visual cortical plasticity. Similarly to human subjects, rodents becoming amblyopic due to early visual deprivation can display spontaneous functional recovery if the deprivation ends within the critical period time window.

AIDS-related mycoses: advances, challenges, and future directions.

Method: Observational studies reporting the prevalence of or risk factors for delirium following acute stroke published in the PubMed, Embase, and Scopus databases before April 16, 2024, were identified.

Consensus review and considerations on TMS to treat depression: A comprehensive update endorsed by the National Network of Depression Centers, the Clinical TMS Society, and the International Federation of Clinical Neurophysiology.

This article updates the prior 2018 consensus statement by the National Network of Depression Centers (NNDC) on the use of transcranial magnetic stimulation (TMS) in the treatment of depression, incorporating recent research and clinical developments. Publications on TMS and depression between September 2016 and April 2024 were identified using methods informed by PRISMA guidelines. The NNDC Neuromodulation Work Group met monthly between October 2022 and April 2024 to define important clinical topics and review pertinent literature.

Humans rationally balance detailed and temporally abstract world models.

How do people model the world's dynamics to guide mental simulation and evaluate choices? One prominent approach, the Successor Representation (SR), takes advantage of temporal abstraction of future states: by aggregating trajectory predictions over multiple timesteps, the brain can avoid the costs of iterative, multi-step mental simulation. Human behavior broadly shows signatures of such temporal abstraction, but finer-grained characterization of individuals' strategies and their dynamic adjustment remains an open question. We developed a task to measure SR usage during dynamic, trial-by-trial learning.

Antithrombin III deficiency and idiopathic intracranial hypertension: a case report.

Background: Idiopathic intracranial hypertension (IIH) is a condition where the pressure of the cerebrospinal fluid in the brain increases without a known cause. It typically affects adults but can also occur in adolescents and children, although it is less common. Numerous elements, including coagulopathy, have been documented in previous cases as potential etiological factors of IIH.

A systematic review and meta-analysis of endovascular treatment of carotid blowout syndrome.

Unlabelled: Carotid Blowout Syndrome (CBS) is a rare and life-threatening condition that necessitates prompt intervention to prevent fatal hemorrhage. This study compares the outcomes of two primary endovascular approaches: reconstructive interventions, which aim to preserve carotid artery function using stents or balloon angioplasty, and deconstructive interventions, which involve vessel occlusion to halt bleeding. A systematic review and meta-analysis were performed by searching multiple databases for relevant studies published from January 2000 to August 2023.

Excitatory/Inhibitory imbalance as a mechanism linking autism and sleep problems.

Sleep problems occur more frequently in individuals with autism spectrum disorder (ASD) than in typically developing individuals, and recent studies support a genetic link between ASD and sleep disturbances. However, it remains unclear how sleep problems may be mechanistically connected to ASD phenotypes. A longstanding hypothesis posits that an imbalance between excitatory and inhibitory (E/I) signaling in the brain underlies the behavioral characteristics of ASD.

Rescue therapy after failed thrombectomy in medium/distal vessel occlusions: A retrospective analysis of an international, multi-center registry.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Intra-arterial Alteplase Thrombolysis After Successful Thrombectomy for Acute Ischemic Stroke in the Posterior Circulation (IAT-TOP): Study protocol and rationale.

Rationale: The Chemical Optimization of Cerebral Embolectomy (CHOICE) trial suggested that the administration of intra-arterial alteplase after successful endovascular thrombectomy (EVT) may improve neurological outcomes in patients with acute ischemic stroke due to large-vessel occlusion (AIS-LVO) in the anterior circulation. However, the use of adjunctive intra-arterial alteplase following successful EVT in acute posterior circulation stroke remains unexplored.

Aims: This study aims to investigate the efficacy and safety of intra-arterial alteplase after successful EVT for AIS-LVO in the posterior circulation.

Impact of number of passes and futile reperfusion in basilar artery occlusion acute ischaemic stroke.

Introduction: Mechanical thrombectomy (MT) is the standard of care in anterior circulation large vessel occlusion. A vital modifiable factor is successful reperfusion. While multiple passes improve the rates of successful reperfusion, previous studies have reported progressively diminishing returns.

Integrated Mendelian Randomization and Single-Cell Transcriptomics Analysis Identifies Critical Blood Biomarkers and Potential Mechanisms in Epilepsy.

Background: Epilepsy has a genetic predisposition, yet causal factors and the dynamics of the immune environment in epilepsy are not fully understood.

Methods: We analyzed peripheral blood samples from epilepsy patients, identifying key genes associated with epilepsy risk through Mendelian randomization, using eQTLGen and genome-wide association studies. The peripheral immune environment's composition in epilepsy was explored using CIBERSORT.

Plasma proteomic signatures of social isolation and loneliness associated with morbidity and mortality.

The biology underlying the connection between social relationships and health is largely unknown. Here, leveraging data from 42,062 participants across 2,920 plasma proteins in the UK Biobank, we characterized the proteomic signatures of social isolation and loneliness through proteome-wide association study and protein co-expression network analysis. Proteins linked to these constructs were implicated in inflammation, antiviral responses and complement systems.

Microsurgical resection now represents a valuable option for treating patients with hemorrhagic or symptomatic lesions. The aim of this study was to provide a practical guide for surgical planning by analyzing postoperative neurological and functional outcomes.

Risk factors for overtaking, rear-end, and door crashes involving bicycles in the United Kingdom: Revisited and reanalysed.

Background And Objective: Relevant research has provided valuable insights into risk factors for bicycle crashes at intersections. However, few studies have focused explicitly on three common types of bicycle crashes on road segments: overtaking, rear-end, and door crashes. This study aims to identify risk factors for overtaking, rear-end, and door crashes that occur on road segments.

Immunometabolism In Brain Aging and Neurodegeneration: Bridging Metabolic Pathways and Immune Responses.

The complex set of interactions between the immune system and metabolism, known as immunometabolism, has emerged as a critical regulator of disease outcomes in the central nervous system. Numerous studies have linked metabolic disturbances to impaired immune responses in brain aging, neurodegenerative disorders, and brain injury. In this review, we will discuss how disruptions in brain immunometabolism balance contribute to the pathophysiology of brain dysfunction.

Subanesthetic Ketamine Ameliorates Activity-Based Anorexia of Adult Mice.

Objective: Anorexia nervosa (AN) is an eating disorder with the second highest mortality of all mental illnesses and high relapse rate, especially among adult females, yet with no accepted pharmacotherapy. A small number of studies have reported that adult females who struggled with severe and relapsing AN experienced sustained remission of the illness following ketamine infusions. Two other reports showed that 30 mg/kg IP ketamine can reduce vulnerability of adolescent mice to activity-based anorexia (ABA), an animal model of AN.
