Machine learning based on event-related oscillations of working memory differentiates between preclinical Alzheimer's disease and normal aging.

Objective: To apply machine learning approaches on EEG event-related oscillations (ERO) to discriminate preclinical Alzheimer's disease (AD) from age- and sex-matched controls.

Methods: Twenty-two cognitively normal preclinical AD participants with elevated amyloid and 21 cognitively normal controls without elevated amyloid completed n-back working memory tasks (n = 0, 1, 2). The absolute and relative power of ERO was extracted using the discrete wavelet transform in the delta, theta, alpha, and beta bands.

Benefits and limits of decellularization on mass-spectrometry-based extracellular matrix proteome analysis of mouse kidney.

The extracellular matrix (ECM) is composed of collagens, ECM glycoproteins, and proteoglycans (also named core matrisome proteins) that are critical for tissue structure and function, and matrisome-associated proteins that balance the production and degradation of the ECM proteins. The identification and quantification of core matrisome proteins using mass spectrometry is often hindered by their low abundance and their propensity to form macromolecular insoluble structures. In this study, we aimed to investigate the added value of decellularization in identifying and quantifying core matrisome proteins in mouse kidney.

Sensory reweighting of postural control requires distinct rambling and trembling sway adaptations.

Background: Implementation of the Sensory Organization Test (SOT) under the rambling-trembling (RM-TR) framework allows for an examination of both individual sensory contributions and compensatory mechanisms, a valuable insight in research and clinical settings. Such investigation could substantially improve our ability to assess and treat fall risk in older adults and people living with neurological disorders.

Research Question: How are RM and TR components of sway influenced by SOT-induced challenges in healthy adults?

Methods: Twenty-three healthy adults (27.

Multimodal exercise training to reduce frailty in people with multiple sclerosis: study protocol for a pilot randomized controlled trial.

Background: Frailty, a syndrome characterized by decreased reserve and resistance to stressors across multiple physiologic systems, is highly prevalent in people living with multiple sclerosis (pwMS), independent of age or disability level. Frailty in MS is strongly associated with adverse clinical outcomes, such as falls, and may aggravate MS-related symptoms. Consequently, there is a pressing necessity to explore and evaluate strategies to reduce frailty levels in pwMS.

Automated Vehicles: Future Initiatives for Occupational Therapy Practitioners and Driver Rehabilitation Specialists.

This article addresses a critically important topic for the occupational therapy (OT) profession and driver rehabilitation specialists (DRS), related to the introduction and deployment of personal and public automated vehicles (AVs); and discusses the current and corresponding changing roles for these professionals. Within this commentary, we provide an overview of the relevant literature on AV regulations, policy, and legislation in North America, the various levels of AV technology, and inclusive and universal design principles to consider in AV deployment for people with disabilities. The role of the OT practitioner and DRS is described within the context of the person-environment-occupation-performance model, and within the guidelines of the Association for Driver Rehabilitation Specialists and the American Occupational Therapy Association.

The Effect of Sensory Reweighting on Postural Control and Cortical Activity in Parkinson's Disease.

Aims: Balance requires the cortical control of visual, somatosensory, and vestibular inputs. The aim of this cross-sectional study was to compare the contributions of each of these systems on postural control and cortical activity using a sensory reweighting approach between participants with Parkinson's disease (PD) and controls.

Methods: Ten participants with PD (age: 72 ± 9; 3 women; Hoehn & Yahr: 2 [1.

Germline heterozygous SH2B3-mutations and (idiopathic) erythrocytosis: Detection of a previously undescribed mutation.

Erythrocytosis or polycythemia refers to a true or apparent increase in hemoglobin or hematocrit. When no etiology of erythrocytosis is identified, people are diagnosed with "idiopathic erythrocytosis" (IE). The identification of new contributing genes has recently improved the diagnostic workup of IE.

Alternative genetic alterations of MYC, BCL2, and/or BCL6 in high-grade B-cell lymphoma (HGBL) and diffuse large B-cell lymphoma (DLBCL): Can we identify different prognostic subgroups?

High-grade B-cell lymphoma (HGBL)/diffuse large B-cell lymphoma (DLBCL) with rearrangements (R) in MYC and BCL2 and/or BCL6 are correlated with poor prognosis. Little is known about the impact of other genetic alterations (gain (G) or amplification (A)) of these genes. The aim of the study was to investigate whether we can identify new prognostic subgroups.

The Role of Rehabilitation for Early-Stage Alzheimer's Disease and Related Dementias: Practice and Priorities.

The World Health Organization describes rehabilitation as interventions that focus on addressing disability through optimizing functional ability for individuals living with various health challenges in their unique daily life contexts. Rehabilitation services are typically seeking to enhance functional capacity and health, either in concert with, or in place of pharmacologic interventions. These services typically fall into 2 categories, restorative, where the client endeavors to return to a prior level of independent function, and compensatory, where s/he may not.

Quantitative hemodynamic assessment of stenotic below-the-knee arteries using spatio-temporal bolus tracking on 4D-CT angiography.

Background: Peripheral arterial disease (PAD) is a chronic occlusive disease that restricts blood flow in the lower limbs, causing partial or complete blockages of the blood flow. While digital subtraction angiography (DSA) has traditionally been the preferred method for assessing blood flow in the lower limbs, advancements in wide beam Computed Tomography (CT), allowing successive acquisition at high frame rate, might enable hemodynamic measurements.

Purpose: To quantify the arterial blood flow in stenotic below-the-knee (BTK) arteries.

Driving Automation for Older Adults with Preclinical Alzheimer's Disease.

Introduction: Older adults with preclinical Alzheimer's disease (AD) show changes in on-road driving performance. The impact of preclinical AD on using automated vehicle (AV) technology is unknown. The aim was to evaluate safety and cognitive workload while operating AV technology in drivers with preclinical AD.

Longitudinal Assessment of Postconcussion Driving: Evidence of Acute Driving Impairment.

Background: Current medical practices and recommendations largely ignore the safety of postconcussion driving, even though commonly used measures of neurocognition, balance, and vestibulo-ocular function show impairment.

Purpose: To compare simulated driving between patients with concussion and controls throughout concussion recovery using a case-control design.

Study Design: Cohort study; Level of evidence, 2.

Reviewing the Regulators of COL1A1.

The collagen family contains 28 proteins, predominantly expressed in the extracellular matrix (ECM) and characterized by a triple-helix structure. Collagens undergo several maturation steps, including post-translational modifications (PTMs) and cross-linking. These proteins are associated with multiple diseases, the most pronounced of which are fibrosis and bone diseases.

Bias reduction improves accuracy and informativity of high-throughput sequencing chimerism assays.

Background And Aims: Chimerism monitoring by means of high-throughput sequencing of biallelic polymorphisms has shown promising advantages for patient follow-up after hematopoietic stem cell transplantation. Yet, the presence of method bias precludes achievement of an assay's theoretically attainable informativity rate, as method bias necessitates the exclusion of some markers. This method bias arises because of preferential observation of one allele over the other, and for some allelic constellations because of stochasticity.
