Optimising episodic encoding within segmented virtual contexts.

The encoding of episodic memories depends on segmentation; memory performance improves when segmentation is available and performance is impaired when segmentation is absent. Indeed, for episodic memories to be created, the encoding of information into long-term memory requires the experience of event boundaries (i.e.

Theories of Arousal Predict a Link Between Heart Rate Variability and Reactive Aggression: Meta-Analytic Results Disagree.

Polyvagal theory posits that habitually aggressive individuals might have an impaired capacity to calm after arousal, which has led to the investigation of Arousal-based biological indicators - "biomarkers" - of aggression, to identify individuals at high risk. The most popular approach in research examining (specifically reactive) aggression is the use of wearable technologies that can non-invasively measure heart rate variability (HRV), a cardiovascular phenomenon impacted by activation of the parasympathetic ("rest and digest") nervous system. But there is a problem: no one has systematically analyzed the results of these studies to determine if HRV is an effective predictor of reactive aggression.

Selinexor in combination with dexamethasone with or without bortezomib in heavily pretreated multiple myeloma: A case series.

This report describes the characteristics and outcomes of 18 heavily pretreated patients with multiple myeloma (MM) who were subsequently treated with selinexor. This is a case series of 18 patients with MM who were treated with selinexor and dexamethasone (Sd) or selinexor, bortezomib, and dexamethasone (SVd) in 12 hospitals in the UK between 2019 and 2021. Eight patients received Sd and 10 patients received SVd.

Both partners' negative emotion drives aggression during couples' conflict.

Researchers examining conflict between intimate partners believe that the experience and expression of emotion drives aggressive behaviour. Intra-personally, increases in negative affect make aggression more likely. Inter-personally, theoretical models suggest that each individuals' perception of their partners' emotion also influences aggression, potentially creating a Violence Escalation Cycle.

Commit to your putting stroke: exploring the impact of quiet eye duration and neural activity on golf putting performance.

Introduction: There is a growing interest in characterizing the cognitive-motor processes that underlie superior performance in highly skilled athletes. The aim of this study was to explore neural markers of putting performance in highly skilled golfers by recording mobile EEG (electroencephalogram) during the pre-shot period.

Methods: Twenty-eight right-handed participants (20 males) with a mean age of 24.

Electrophysiologic and cardiovascular manifestations of Duchenne and Becker muscular dystrophies.

There have been significant advances in the diagnosis and management of the hereditary muscular disorders Duchenne and Becker muscular dystrophy (DMD and BMD). Cardiac electrophysiologic and cardiovascular involvement has long been important in the surveillance, care, and prognosis of patients with both BMD and DMD and is the leading cause of mortality in patients with DMD. With improved long-term prognosis, rhythm disorders and progressive cardiomyopathy with resultant heart failure are increasingly common.

Investigating the Brain Mechanisms of Externally Cued Sit-to-Stand Movement in Parkinson's Disease.

Background: One of the more challenging daily-life actions for Parkinson's disease patients is starting to stand from a sitting position. Parkinson's disease patients are known to have difficulty with self-initiated movements and benefit from external cues. However, the brain processes underlying external cueing as an aid remain unknown.

Neural correlates of motor imagery and execution in real-world dynamic behavior: evidence for similarities and differences.

A large body of evidence shows that motor imagery and action execution behaviors result from overlapping neural substrates, even in the absence of overt movement during motor imagery. To date it is unclear how neural activations in motor imagery and execution compare for naturalistic whole-body movements, such as walking. Neuroimaging studies have not directly compared imagery and execution during dynamic walking movements.

Left Atrial Appendage Closure: Therapy Overview and Future Perspective.

The left atrial appendage (LAA) has gained increasing attention in the field of cardiology as a potential site for intervention in patients with atrial fibrillation (AF) and an elevated risk of thromboembolic events. Left atrial appendage occlusion (LAAO) has emerged as a promising therapeutic strategy to mitigate the risk of stroke and systemic embolism, especially in individuals who are unsuitable candidates for long-term anticoagulation therapy. This review aims to provide a comprehensive analysis of the current state of LAAO, encompassing its anatomic considerations, procedural techniques, clinical outcomes, and future directions.

The evolving landscape of COVID-19 and post-COVID condition in patients with chronic lymphocytic leukemia: A study by ERIC, the European research initiative on CLL.

In this retrospective international multicenter study, we describe the clinical characteristics and outcomes of patients with chronic lymphocytic leukemia (CLL) and related disorders (small lymphocytic lymphoma and high-count monoclonal B lymphocytosis) infected by SARS-CoV-2, including the development of post-COVID condition. Data from 1540 patients with CLL infected by SARS-CoV-2 from January 2020 to May 2022 were included in the analysis and assigned to four phases based on cases disposition and SARS-CoV-2 variants emergence. Post-COVID condition was defined according to the WHO criteria.

Phosphorus adsorption and organic release from dried and thermally treated water treatment sludge.

The study investigated water treatment sludge (WTS) as a phosphorus (P) adsorbent and examined the release of organic matter during the P adsorption process. Previous studies indicated that WTS is an effective adsorbent for P but also releases organic matter, which may affect the organoleptic properties of treated water, but no study has characterised organic release and conducted an in-depth study on its behaviours. This study characterised the organic release during the P adsorption process from four different WTS samples.

Metabolic Alterations in Multiple Myeloma: From Oncogenesis to Proteasome Inhibitor Resistance.

Despite significant improvements in treatment strategies over the past couple of decades, multiple myeloma (MM) remains an incurable disease due to the development of drug resistance. Metabolic reprogramming is a key feature of cancer cells, including MM, and acts to fuel increased proliferation, create a permissive tumour microenvironment, and promote drug resistance. This review presents an overview of the key metabolic adaptations that occur in MM pathogenesis and in the development of resistance to proteasome inhibitors, the backbone of current MM therapy, and considers the potential for therapeutic targeting of key metabolic pathways to improve outcomes.

Ocular pathology in aquarium fish with a focus on the Syngnathidae and Apogonidae families.

This study catalogued ocular pathology in fish histopathology submissions to a specialist diagnostic service and investigated associations with species and systemic disease, with a focus on species of conservation interest. Cross-tabulations and Fisher's exact tests were used to identify associations among the variables and results are reported as prevalence ratios (PRs) with 95% confidence intervals (CI). Of 12,488 reports reviewed, ocular histology examination was available for 4,572 submissions, in which histopathological ocular lesions were identified in 18% (813/4572).

Teachers' emotions in the time of COVID: Thematic analysis of interview data reveals drivers of professional agency.

Purpose: We explored two complex phenomena associated with effective education. First, teachers' professional agency, the volitional actions they take in response to perceived opportunities, was examined to consider individual differences in its enactment. Second, "strong" emotions have been proposed as important in teaching and learning, and we wished to clarify which basic emotions might be involved, besides curiosity, which is a known emotional factor in engagement in teaching.

Animals Studied: Retrospective review of dogs that underwent SPL placement for treatment of ocular disease at the Ophthalmology Department, University of Bristol Small Animal Hospital between 2017 and 2021.

Procedure(s): Data recorded included signalment, history, diagnosis, treatment, reason for SPL placement, uni- or bilateral placement, duration of placement, complications, and outcome.

The neural response is heightened when watching a person approaching compared to walking away: Evidence for dynamic social neuroscience.

The action observation network has been proposed to play a key role in predicting the action intentions (or goals) of others, thereby facilitating social interaction. Key information when interacting with others is whether someone (an agent) is moving towards or away from us, indicating whether we are likely to interact with the person. In addition, to determine the nature of a social interaction, we also need to take into consideration the distance of the agent relative to us as the observer.

Development of a Care Pathway for Atrial Fibrillation Patients in the Emergency Department.

Atrial fibrillation (AF) is the most common cardiac arrhythmia and its prevalence is continuously increasing in the United States, leading to a progressive rise in the number of disease-related emergency department (ED) visits and hospitalizations. Although optimal long-term outpatient management for AF is well defined, the guidelines for optimal ED management of acute AF episodes is less clear. Studies have demonstrated that discharging patients with AF from the ED after acute stabilization is both safe and cost effective; however, the majority of these patients in the United States and in our institution are admitted to the hospital.

Mutations Identified Using NGS Comprise the Overwhelming Majority of Disruptions in CLL: Results From a Multicentre Study.

Limited data exists to show the correlation of (tumour protein 53) mutation detected by Next generation sequencing (NGS) and the presence/absence of deletions of 17p13 detected by FISH. The study which is the largest series to date includes 2332 CLL patients referred for analysis of del(17p) by FISH and mutations by NGS before treatment. Using a 10% variant allele frequency (VAF) threshold, cases were segregated into high burden mutations (≥10%) and low burden mutations (<10%).

Objective: To compare the incidence of corneal injury during general anesthesia (GA) and the immediate post-operative period in eyes protected with topical ocular lubricant alone with eyes protected with topical lubricant followed by complete eyelid closure using tape.

Animals Studied: One hundred client-owned dogs (200 eyes) undergoing GA for MRI scan.

Methods: Patients had ocular lubricant applied to both eyes upon induction of anesthesia.

Implantation of a Dual-chamber Pacemaker in a Patient with Dextrocardia, Situs Inversus, and Sick Sinus Syndrome.

Situs inversus with dextrocardia is a rare congenital anomaly that presents a unique challenge for the consultant electrophysiologist. Implantation of cardiac device in these patients may be challenging owing to their individual cardiac and vascular anatomy. Consequently, adverse procedural outcomes are more common in this group and an informed pre- and intraoperative approach is critical.
