Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is the most common form of vascular cognitive impairment. White matter hyperintensities (WMH) secondary to SIVCI often result in impaired executive function. Cognitive reserve is a property of the brain that allows for preserved cognitive performance given brain injury or disease.

Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is highly prevalent in older individuals. White matter hyperintensities (WMH) are a defining feature of SIVCI. There are sex differences in SIVCI, with females having higher volume and faster WMH progression than males.

Public Health.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is the most common form of vascular cognitive impairment. White matter hyperintensities (WMH) are hallmarks of SIVCI and are associated with impaired executive function. Cognitive reserve is a property of the brain that moderates an individual's ability to maintain cognitive performance given brain injury or pathology.

Biomarkers.

Background: Subcortical ischemic vascular cognitive impairment (SIVCI) is the most common form of vascular cognitive impairment. Exercise is a potentially effective intervention for SIVCI. However, the mechanisms through which exercise promotes brain health and cognitive function are not well understood.

The Role of Machine Learning in the Detection of Cardiac Fibrosis in Electrocardiograms: Scoping Review.

Background: Cardiovascular disease remains the leading cause of mortality worldwide. Cardiac fibrosis impacts the underlying pathophysiology of many cardiovascular diseases by altering structural integrity and impairing electrical conduction. Identifying cardiac fibrosis is essential for the prognosis and management of cardiovascular disease; however, current diagnostic methods face challenges due to invasiveness, cost, and inaccessibility.

Eight novel diagnostic markers differentiate lineages of the highly invasive myrtle rust pathogen .

is the causal agent of myrtle rust in over 480 species within the family Myrtaceae. Lineages of are structured by their hosts in the native range, and some have success in infecting newly encountered hosts. For example, the pandemic biotype has spread beyond South America, and proliferation of other lineages is an additional risk to biodiversity and industries.

A Prime-Boost Vaccination Approach Induces Lung Resident Memory CD8+ T Cells Derived from Central Memory T Cells That Prevent Tumor Lung Metastasis.

Memory T cells play a key role in immune protection against cancer. Vaccine-induced tissue-resident memory T (TRM) cells in the lung have been shown to protect against lung metastasis. Identifying the source of lung TRM cells can help to improve strategies, preventing tumor metastasis.

Improvements in Function With Inpatient Rehabilitation in a Patient Following a Traumatic Brain Injury: A Case Report.

Traumatic brain injury has been a leading cause of morbidity, mortality, and disability. Patients may experience cognitive and functional decline, depending on the severity. In this case report, a patient presents with a closed-head traumatic brain injury that was sustained after a motor vehicle accident.

The Canadian Prospective Cohort Study to understand progression in multiple sclerosis: baseline characteristics.

Background: Disease progression is observed across the spectrum of people with multiple sclerosis (MS) and identification of effective treatment strategies to halt progression remains one of the greatest unmet clinical needs.

Objectives: The Canadian Prospective Cohort Study to Understand Progression in MS (CanProCo) was designed to evaluate a wide range of factors associated with the onset and rate of clinical disease progression in MS and to describe the interplay between these factors.

Design: A prospective cohort study.

Cardiac Anomaly: Reverse Takotsubo Following Gallbladder Surgery.

Takotsubo cardiomyopathy is an acute but often reversible left ventricular dysfunction commonly triggered by emotional stress. There are multiple variants within the general condition; however, reverse Takotsubo cardiomyopathy is a rare variant of stress-induced cardiomyopathy affecting the basilar segment of the left ventricle. This commonly manifests in younger women with clinical presentations similar to acute coronary syndrome.

'We're taught green is good': Perspectives on time in range and time in tight range from youth with type 1 diabetes, and parents of youth with type 1 diabetes.

Aims: Continuous glucose monitoring (CGM) systems are standard of care for youth with type 1 diabetes with the goal of spending >70% time in range (TIR; 70-180 mg/dL, 3.9-10 mmol/L). We aimed to understand paediatric CGM user experiences with TIR metrics considering recent discussion of shifting to time in tight range (TITR; >50% time between 70 and 140 mg/dL, 3.

Physical reserve and its underpinning functional neural networks moderate the relationship between white matter hyperintensity and postural balance in older adults with subcortical ischemic vascular cognitive impairment.

White matter hyperintensities (WMH) are markers of subcortical ischemic vascular cognitive impairment (SIVCI) associated with impaired postural balance. Physical reserve (PR) is a recently established construct that reflects one's capacity to maintain physical function despite brain pathology. This cross-sectional study aims to map functional networks associated with PR, and examining the relationship between PR, WMH, and postural balance.

Centrosome-organized plasma membrane infoldings linked to growth of a cortical actin domain.

Regulated cell shape change requires the induction of cortical cytoskeletal domains. Often, local changes to plasma membrane (PM) topography are involved. Centrosomes organize cortical domains and can affect PM topography by locally pulling the PM inward.

End-of-Life Care of a Patient With Pontine Stroke and Prolonged Hospitalization: A Case Report.

Stroke is a leading cause of long-term disability in the United States that can lead to loss of function and consciousness. With the abrupt onset of the brain insult, end-of-life care discussions are an important attribute of respecting the patient's best wishes and upholding the ethical principles of autonomy, beneficence, nonmaleficence, fidelity, and justice. Furthermore, the topic of extending life support to individuals with poor prognostic factors of improvement in quality of life and functional recovery has been a continued topic of debate due to a multitude of factors, including the wishes of the patient, familial emotions, cultural beliefs, and religious influences.

Fecal incontinence patients categorized based on anal pressure and electromyography: Anal sphincter damage and clinical symptoms.

Background: Disruption of external anal sphincter muscle (EAS) is an important factor in the multifactorial etiology of fecal incontinence (FI).

Objectives: We categorize FI patients into four groups based on the location of lesion in neuromuscular circuitry of EAS to determine if there are differences with regards to fecal incontinence symptoms severity (FISI) score, age, BMI, obstetrical history, and anal sphincter muscle damage.

Methods: Female patients (151) without any neurological symptoms, who had undergone high-resolution manometry, anal sphincter EMG, and 3D ultrasound imaging of the anal sphincter were assessed.

SSiT: Saliency-Guided Self-Supervised Image Transformer for Diabetic Retinopathy Grading.

Self-supervised Learning (SSL) has been widely applied to learn image representations through exploiting unlabeled images. However, it has not been fully explored in the medical image analysis field. In this work, Saliency-guided Self-Supervised image Transformer (SSiT) is proposed for Diabetic Retinopathy (DR) grading from fundus images.

Multiplexed effector screening for recognition by endogenous resistance genes using positive defense reporters in wheat protoplasts.

Plant resistance (R) and pathogen avirulence (Avr) gene interactions play a vital role in pathogen resistance. Efficient molecular screening tools for crops lack far behind their model organism counterparts, yet they are essential to rapidly identify agriculturally important molecular interactions that trigger host resistance. Here, we have developed a novel wheat protoplast assay that enables efficient screening of Avr/R interactions at scale.
