Advancements in diagnosing Post-concussion Syndrome: insights into epidemiology, pathophysiology, neuropathology, neuroimaging, and salivary biomarkers.

Post-Concussion Syndrome (PCS) represents a complex constellation of symptoms that persist following a concussion or mild traumatic brain injury (mTBI), with significant implications for patient care and outcomes. Despite its prevalence, diagnosing PCS presents considerable challenges due to the subjective nature of symptoms, the absence of specific diagnostic tests, and the overlap with other neurological and psychiatric conditions. This review explores the multifaceted diagnostic challenges associated with PCS, including the heterogeneity of symptom presentation, the limitations of current neuroimaging techniques, and the overlap of PCS symptoms with other disorders.

The Association Between Traumatic Brain Injury and the Risk of Cognitive Decline: An Umbrella Systematic Review and Meta-Analysis.

Background: There is currently increasing interest in the implication of traumatic brain injury (TBI) as a potential risk factor for long-term neurodegenerative conditions, such as dementia and Alzheimer's disease (AD). In this context, we performed a systematic review and meta-analysis to evaluate the association between TBI and the risk of dementia.

Methods: A systematic search was performed across multiple electronic databases, including PubMed, Embase, and Cochrane Library, to identify relevant meta-analyses and cohort studies.

A risk-risk tradeoff approach for incorporating the public's risk perceptions into quantitative microbial risk assessment.

In public health, risk experts often define acceptable risk targets without community input. We developed a novel method for applying behavioral microeconomics to integrate individuals' risk preferences into risk assessment. To demonstrate this methodology, we explored a risk-risk tradeoff case scenario: increased asthma risk from increased cleaning and disinfection (C&D) and increased infection risk from decreased C&D for healthcare staff.

"My name is bond. Green bond." Informational efficiency of climate finance markets.

This paper investigates the informational efficiency of green bond markets using a recently introduced quantitative measure for market inefficiency. The paper finds that, first, the degree of inefficiency of the green bond market is very similar to that of benchmark bond markets; in addition, fundamental factors that drive bond prices in general also drive prices for green bonds. The green bond market, however, is less affected by challenging environments such as the COVID outbreak in 2020 and the inflation shock in 2022/2023 than the benchmark markets.

Shared leadership and team creativity: Examining effects of shared leadership level and concentration and the countervailing mechanisms.

Integrating insights from team hierarchy literature and shared leadership research, we propose and test a model that illuminates the positive and negative team processes through which shared leadership relates to team creativity. We use a social network lens to examine both shared leadership level (indexed by team density of informal leadership ties) and shared leadership concentration (indexed by team centralization of such ties). With a sample of 136 work teams and three waves of surveys, we found that shared leadership concentration weakens the positive effect of shared leadership level on team creativity.

Materials And Methods: A Google Form (Google, UK) was electronically distributed to UK ophthalmologists with a special interest in cornea from November 2023 to June 2024. The survey consisted of 13 mandatory questions.

Foreign Accent Syndrome: insights from Neuroimaging and Pathophysiological mechanisms.

Foreign Accent Syndrome (FAS) is a rare and complex speech disorder characterized by the sudden emergence of a foreign accent, typically following neurological events such as strokes, traumatic brain injuries, or neurodegenerative diseases. This comprehensive review explores the pathophysiology, neuroimaging findings, and prevalence of FAS. Neuroimaging studies, including MRI and fMRI, reveal significant brain reorganization predominantly in the left hemisphere, involving regions such as the superior temporal gyrus and medial frontal structures.

High-performance human resource practices, organizational identification and employee commitment: the moderating role of organizational culture.

Purpose: Drawing on social exchange and social identity theories, this study examines the mediating role of organizational identification on the relationship between high-performance human resource practices (HPHRPs) and employee commitment. The study further examines the moderating role of organizational culture in this mediated relationship.

Method: A cross-sectional survey was conducted with 340 employees from state-owned enterprises in China, and SPSS was used to test the hypothesized relationships.

Communicating Probabilities of Cervical Cancer Screening Results with Icon Arrays or Tree Diagrams: A Longitudinal Experiment.

Simple graphical displays such as icon arrays and tree diagrams have been proposed for communicating health risks and supporting informed decisions. The UK's National Health Service (NHS) uses tree diagrams to communicate the chances of different cervical cancer screening results, but their effectiveness has not been compared to icon arrays. We conducted a well-powered longitudinal experiment involving 3,100 UK women eligible for cervical screening (25-64 years) to examine the effectiveness of icon arrays to communicate possible cervical screening results, relative to the UK NHS's tree diagram and to a numerical-only format.

Enhancing the Photovoltaic Efficiency of InGaN/GaN Quantum Well Intermediate Band Solar Cells Using Combined Electric and Magnetic Fields.

This study presents a theoretical investigation into the photovoltaic efficiency of InGaN/GaN quantum well-based intermediate band solar cells (IBSCs) under the simultaneous influence of electric and magnetic fields. The finite element method is employed to numerically solve the one-dimensional Schrödinger equation within the framework of the effective-mass approximation. Our findings reveal that electric and magnetic fields significantly influence the energy levels of electrons and holes, optical transition energies, open-circuit voltages, short-circuit currents, and overall photovoltaic conversion performances of IBSCs.

Lymphatic Disorder Management in Pediatric Patients With Congenital Heart Disease in European Pediatric Cardiology Centers: Current Status, Disparities, and Future Considerations.

Background: Lymphatic disorders such as protein-losing enteropathy, plastic bronchitis, and chylothorax are important complications of the Fontan circulation and ultimately result in an increased risk of early death. Several European centers are now performing lymphatic procedures. The aim of this study is to map the extent of these lymphatic disorders and treatments provided across European pediatric cardiology centers.

Praise Is for Actions That Are Neither Expected nor Required.

In six studies, we examined two foundational questions about moral praise. First, what makes an action praiseworthy? In Study 1, participants reported that actions that exceed duties (compared with dutiful actions) deserve greater praise and are perceived as less likely to happen. Second, what do observers infer from praise? Praise may communicate information about local norms.

Charting the Course of the Nursing Professional Identity: A Qualitative Descriptive Study on the Identity of Nurses Working in Care for Older Adults.

Aims: To explore and describe the meaning of nurses working in care for older adults give to the nursing professional identity.

Design: A qualitative approach was taken.

Methods: Semi-structured interviews were conducted with 50 bachelor and vocational-educated nurses working in care for older adults.

The public as a definitive stakeholder of corporate environmental sustainability practices: A cross-national institutional approach.

An emerging body of literature connects the well-known Varieties of Capitalism framework (and its variants) with the propensity of nations to move away from hydrocarbons. Our study extends this work by exploring how macro-level institutional configurations matter for public expectations towards corporate environmental sustainability practices. By linking survey data of public-as-stakeholders to institutional systems encompassing 16 countries (N = 7156), we use multi-level modelling to test the explanatory power of a theoretically well-refined recent construct, namely, the Varieties of Institutional Systems - and discover significant variations associated with public expectations across different institutional systems.

Cost-effectiveness of a novel AI technology to quantify coronary inflammation and cardiovascular risk in patients undergoing routine Coronary Computed Tomography Angiography.

Aims: Coronary Computed Tomography Angiography (CCTA) is a first line investigation for chest pain in patients with suspected obstructive coronary artery disease (CAD). However, many acute cardiac events occur in the absence of obstructive CAD. We assessed the lifetime cost-effectiveness of integrating a novel artificial intelligence-enhanced image analysis algorithm (AI-Risk) that stratifies the risk of cardiac events by quantifying coronary inflammation, combined with the extent of coronary artery plaque and clinical risk factors, by analysing images from routine CCTA.

Investigating the Impact of Nutrition and Oxidative Stress on Attention Deficit Hyperactivity Disorder.

Attention deficit hyperactivity disorder (ADHD) is the most common childhood-onset neurodevelopmental disorder, characterized by difficulty maintaining attention, impulsivity, and hyperactivity. While the cause of this disorder is still unclear, recent studies have stated that heredity is important in the development of ADHD. This is linked to a few comorbidities, including depression, criminal behavior, and anxiety.

Community-based complex interventions to sustain independence in older people, stratified by frailty: a systematic review and network meta-analysis.

Background: Sustaining independence is important for older people, but there is insufficient guidance about which community health and care services to implement.

Objectives: To synthesise evidence of the effectiveness of community services to sustain independence for older people grouped according to their intervention components, and to examine if frailty moderates the effect.

Review Design: Systematic review and network meta-analysis.

What is the relationship between changes in the size of economies and mortality derived population health measures in high income countries: A causal systematic review.

Context: The economy has been long recognised as an important determinant of population health and a healthy population is considered important for economic prosperity.

Aim: To systematically review the evidence for a causal bidirectional relationship between aggregate economic activity (AEA) at national level for High Income Countries, and 1) population health (using mortality and life expectancy rates as indicators) and 2) inequalities in population health.

Methods: We undertook a systematic review of quantitative studies considering the relationship between AEA (GDP, GNI, GNP or recession) and population health (mortality or life expectancy) and inequalities for High Income Countries.

How to activate threat perceptions in behavior research: A simple technique for inducing health and resource scarcity threats.

Understanding our cognitive and behavioral reactions to large-scale collective problems involving health and resource scarcity threats, such as the COVID-19 pandemic, helps us be better prepared for future collective threats. However, existing studies on these threats tend to be restricted to correlational data, partly due to a lack of reliable experimental techniques for manipulating threat perceptions. In four preregistered experiments (N = 5152), we developed and validated an experimental technique that can separately activate perceptions of personal health threat or resource scarcity threat, either in the specific context of the COVID-19 pandemic or in general.

Comparative Safety and Effectiveness of Ustekinumab and Anti-TNF in Elderly Crohn's Disease Patients.

Background: Biologic therapies are associated with increased infection risk among elderly patients with inflammatory bowel disease (IBD). However, there are few data on the safety and effectiveness of ustekinumab compared with anti-tumor necrosis factor (anti-TNF) agents in the elderly.

Methods: The study sought to compare the safety and effectiveness of ustekinumab and anti-TNF agents in elderly Crohn's disease (CD) patients.

Exploring Symptom Overlaps: Post-COVID-19 Neurological Syndrome and Post-Concussion Syndrome in Athletes.
