From histology to diagnosis: Leveraging pathology foundation models for glioma classification.

The fifth edition of the WHO classification of brain tumors increasingly emphasizes the role of extensive genetic testing in the diagnosis of gliomas. In this context, computational pathology foundation models (FMs) present a promising approach for inferring molecular entities directly from conventional, H&E-stained histological images, potentially reducing the need for genetic analysis. We conducted a robust investigation into the ability of five established FMs to generate effective embeddings for downstream glioma classification using three datasets (TCGA, n=839 samples; EBRAINS, n=786 samples; TUM, n=250 samples) and state-of-the-art augmentation techniques.

The goal is to develop a model that enhances risk stratification and informs personalized treatment strategies.

Materials And Methods: Within the AURORA retrospective trial, patients (n = 352) who received surgical resection followed by post-operative stereotactic radiotherapy (SRT) were collected from seven hospitals.

Quality of life in older adults is enhanced by piano practice: Results from a randomized controlled trial.

Although hobbies can improve quality of life (QoL), the role that music might play in healthy aging still needs to be established. The aim of the present study was to investigate the causal influence of piano practice on QoL in seniors. Furthermore, we aimed to identify brain regions of the reward circuit that are related to QoL and piano practice.

Increased functional connectivity of motor regions and dorsolateral prefrontal cortex in musicians with focal hand dystonia.

Background: Musician's dystonia is the most common form of focal task-specific dystonia and is suggested to be the result of dysfunctional communication among sensory-motor networks. Thus far, few functional connectivity studies have investigated musician's dystonia specifically, leaving its exact pathophysiological mechanisms unclear. The goal of this study was to verify connectivity findings from other task-specific dystonias on a large sample of musician's hand dystonia patients and to analyze associations with possible adverse childhood experiences, a suggested risk factor for dystonia.

Acquisition of musical skills and abilities in older adults-results of 12 months of music training.

Background: Older adults can acquire new skills across different domains. Practicing a musical instrument has been identified as a promising activity for improving cognition, promoting well-being, and inducing brain plasticity in older individuals. However, the mechanisms of these changes are still poorly understood.

Stress in Musicians with and Without Focal Dystonia Is Not Reflected in Limbic Circuit Activation.

Background: Musicians' dystonia (MD) is a movement disorder with several established risk factors, but the exact pathophysiology remains unknown. Recent research suggests dysfunction in sensory-motor, basal ganglia, cerebellar, and limbic loops as potential causes. Adverse childhood experiences are also considered risk factors.

Fabrication and Characterization of PDMS Waveguides for Flexible Optrodes.

With the growth of optogenetic research, the demand for optical probes tailored to specific applications is ever rising. Specifically, for applications like the coiled cochlea of the inner ear, where planar, stiff, and nonconformable probes can hardly be used, transitioning from commonly used stiff glass fibers to flexible probes is required, especially for long-term use. Following this demand, polydimethylsiloxane (PDMS) with its lower Young's modulus compared to glass fibers can serve as material of choice.

Defining the clinical and procedural opportunities available to residents during rural rotations.

Introduction: Many emergency medicine (EM) residency programs include clinical rotations in rural emergency departments ("rural rotations") as part of their curriculum. These rotations are designed to expose residents to clinical scenarios that are less frequently encountered in tertiary centers. The objective of this study was to determine the rate at which residents were exposed to certain clinical and procedural experiences (CPEs) while on rural rotations compared to their usual academic training hospital.

Increased functional connectivity in the right dorsal auditory stream after a full year of piano training in healthy older adults.

Learning to play an instrument at an advanced age may help to counteract or slow down age-related cognitive decline. However, studies investigating the neural underpinnings of these effects are still scarce. One way to investigate the effects of brain plasticity is using resting-state functional connectivity (FC).

Efficient SNN multi-cores MAC array acceleration on SpiNNaker 2.

The potential low-energy feature of the spiking neural network (SNN) engages the attention of the AI community. Only CPU-involved SNN processing inevitably results in an inherently long temporal span in the cases of large models and massive datasets. This study introduces the MAC array, a parallel architecture on each processing element (PE) of SpiNNaker 2, into the computational process of SNN inference.

Focal Dystonia and the Stress Network: The Role of Stress Vulnerability and Adverse Childhood Experiences in the Development of Musician's Dystonia.

Musician's dystonia is often described as a neurological disorder, resulting from reduced inhibition in the basal ganglia and the cerebellum and dysfunctional cortical plasticity. However, several studies over the last decades support the hypothesis that psychological factors play an important role in the aetiology of dystonia, contradicting its classification as "purely neurological". Especially adverse childhood experiences (ACEs) such as neglect, maltreatment, or household dysfunction may influence the sensorimotor system, additionally to the impact they have on psychological traits.

Fine motor control improves in older adults after 1 year of piano lessons: Analysis of individual development and its coupling with cognition and brain structure.

Musical training can improve fine motor skills and cognitive abilities and induce macrostructural brain changes. However, it is not clear whether the changes in motor skills occur simultaneously with changes in cognitive and neurophysiological parameters. In this study, 156 healthy, musically naïve and right-handed older adults were recruited and randomly assigned to a piano training or a music listening group.

Music interventions in 132 healthy older adults enhance cerebellar grey matter and auditory working memory, despite general brain atrophy.

Normal aging is associated with brain atrophy and cognitive decline. Working memory, involved in cognitive functioning and daily living, is particularly affected. Music training gained momentum in research on brain plasticity and possible transfer effects of interventions on working memory, especially in the context of healthy aging.

Low Self-Esteem and Music Performance Anxiety Can Predict Depression in Musicians.

Background: Music performance anxiety (MPA) is an issue concerning musicians from all levels but is still a rather neglected topic in the education and employment of musicians. This study investigated the link between self-esteem, MPA, and depression within a German-speaking sample of musicians of different professions. The underlying question of this study was generated during psychotherapy treatment of musicians with depression and MPA.

Automotive Radar Processing With Spiking Neural Networks: Concepts and Challenges.

Frequency-modulated continuous wave radar sensors play an essential role for assisted and autonomous driving as they are robust under all weather and light conditions. However, the rising number of transmitters and receivers for obtaining a higher angular resolution increases the cost for digital signal processing. One promising approach for energy-efficient signal processing is the usage of brain-inspired spiking neural networks (SNNs) implemented on neuromorphic hardware.

Influence of Adverse Childhood Experiences and Perfectionism on Musician's Dystonia: a Case Control Study.

Background: Musician's dystonia (MD) is a task-specific movement disorder characterized by muscle cramps and impaired voluntary motor-control whilst playing a musical instrument. Recent studies suggest an involvement of adverse childhood experiences (ACEs) in the development of MD.

Objectives: By investigating the prevalence of ACEs in MD patients with perfectionism as possible mediating factor this study aims to gain further insights into the etiology of MD.

Association of Music Interventions With Health-Related Quality of Life: A Systematic Review and Meta-analysis.

Importance: Increasing evidence supports the ability of music to broadly promote well-being and health-related quality of life (HRQOL). However, the magnitude of music's positive association with HRQOL is still unclear, particularly relative to established interventions, limiting inclusion of music interventions in health policy and care.

Objective: To synthesize results of studies investigating outcomes of music interventions in terms of HRQOL, as assessed by the 36- and 12-Item Health Survey Short Forms (SF-36 and SF-12).

Evidence of cortical thickness increases in bilateral auditory brain structures following piano learning in older adults.

Morphological differences in the auditory brain of musicians compared to nonmusicians are often associated with life-long musical activity. Cross-sectional studies, however, do not allow for any causal inferences, and most experimental studies testing music-driven adaptations investigated children. Although the importance of the age at which musical training begins is widely recognized to impact neuroplasticity, there have been few longitudinal studies examining music-related changes in the brains of older adults.

Six Months of Piano Training in Healthy Elderly Stabilizes White Matter Microstructure in the Fornix, Compared to an Active Control Group.

While aging is characterized by neurodegeneration, musical training is associated with experience-driven brain plasticity and protection against age-related cognitive decline. However, evidence for the positive effects of musical training mostly comes from cross-sectional studies while randomized controlled trials with larger sample sizes are rare. The current study compares the influence of six months of piano training with music listening/musical culture lessons in 121 musically naïve healthy elderly individuals with regard to white matter properties using fixel-based analysis.

Sea-ice derived meltwater stratification slows the biological carbon pump: results from continuous observations.

The ocean moderates the world's climate through absorption of heat and carbon, but how much carbon the ocean will continue to absorb remains unknown. The North Atlantic Ocean west (Baffin Bay/Labrador Sea) and east (Fram Strait/Greenland Sea) of Greenland features the most intense absorption of anthropogenic carbon globally; the biological carbon pump (BCP) contributes substantially. As Arctic sea-ice melts, the BCP changes, impacting global climate and other critical ocean attributes (e.

Neural Plasticity in a French Horn Player with Bilateral Amelia.

Precise control of movement and timing play a key role in musical performance. This motor skill requires coordination across multiple joints, muscles, and limbs, which is acquired through extensive musical training from childhood on. Thus, making music can be a strong driver for neuroplasticity.

Improved Speech in Noise Perception in the Elderly After 6 Months of Musical Instruction.

Understanding speech in background noise poses a challenge in daily communication, which is a particular problem among the elderly. Although musical expertise has often been suggested to be a contributor to speech intelligibility, the associations are mostly correlative. In the present multisite study conducted in Germany and Switzerland, 156 healthy, normal-hearing elderly were randomly assigned to either piano playing or music listening/musical culture groups.

Impact of Psychic Traumatization on the Development of Musicians' Dystonia: Six Exploratory Case Studies.

Objective: Musician's dystonia represents a special case of focal dystonia. It is described as a task-specific movement disorder which presents itself as muscular incoordination or loss of voluntary fine-motor control of extensively trained movements while a musician is playing the instrument. Several triggering factors have been identified, such as overuse, chronic pain, perfectionism, and anxiety disorders.

Train the brain with music (TBM): brain plasticity and cognitive benefits induced by musical training in elderly people in Germany and Switzerland, a study protocol for an RCT comparing musical instrumental practice to sensitization to music.

Background: Recent data suggest that musical practice prevents age-related cognitive decline. But experimental evidence remains sparse and no concise information on the neurophysiological bases exists, although cognitive decline represents a major impediment to healthy aging. A challenge in the field of aging is developing training regimens that stimulate neuroplasticity and delay or reverse symptoms of cognitive and cerebral decline.
