Background: re-hospitalisation after discharge following index stroke varies over time and with age and comorbidity. There is little knowledge about whether stroke unit care reduces the need of re-admissions.
Objectives: to examine whether stroke unit care as compared with care in general medical wards was associated with fewer re-hospitalisations for conditions judged to be secondary to acute stroke and to identify the influence of stroke severity on re-admission rates.
Design: we conducted a one-year randomised study to compare the outcome of treatment at an acute stroke unit in a care continuum with the outcome of treatment at general medical wards.
Settings: acute and geriatric hospitals in Göteborg, Sweden.
Subjects: 216 elderly patients aged >or=70 years discharged to their own homes or to institutionalised living after index stroke.
Methods: comparison of comorbidity classified according to Charlson's morbidity index, re-admission rates, length of hospital stay, number of re-admissions and diagnoses between a group treated at a stroke unit and a group treated at general wards.
Results: the re-admission rates, length of hospital stay and causes of re-admissions did not differ between the two groups. Complications related to the damage to the brain and concomitant heart disease were the most common causes of re-admissions in both groups. Index stroke severity did not influence the re-admission rates.
Conclusions: re-admissions for conditions judged to be secondary to acute stroke were equal in the two groups in this prospective study.

Echocardiographic index of left ventricular performance for prognostication in transthyretin cardiac amyloidosis: the central role of stroke volume index.
J Cardiovasc Med (Hagerstown)

Introduction: Cardiac amyloidosis typically causes restrictive cardiomyopathy, in which the impairment of diastolic function is dominant. Echocardiography provides prognostic information through some important parameters: left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS). However, LVEF often remains preserved despite disease progression, and GLS is not routinely performed as it is limited by suboptimal image quality.

In Alzheimer's disease (AD), amyloid-β (Aβ) triggers the aggregation and spreading of tau pathology, which drives neurodegeneration and cognitive decline. However, the pathophysiological link between Aβ and tau remains unclear, which hinders therapeutic efforts to attenuate Aβ-related tau accumulation. Aβ has been found to trigger neuronal hyperactivity and hyperconnectivity, and preclinical research has shown that tau spreads across connected neurons in an activity-dependent manner.

The genetic relationship between migraine and stroke remains underexplored, particularly in the context of druggable targets. Previous studies have been limited by small sample sizes and a lack of focus on genetic-targeted therapies for these conditions. We analyzed the association and causality between migraine and stroke using multivariable logistic regression in the UK Biobank cohort and Mendelian randomization (MR) analyses based on genome-wide association study (GWAS) data.

Purpose: To examine the effects of different warm-up methods on 50 m breaststroke performance in both breaststroke specialists and individual medley swimmers.
Methods: 18 swimmers (breaststroke group: 9, individual medley group: 9) who met the qualification standards for the National Intercollegiate Athletic Games participated in this study. Each participant completed four different warm-up protocols (a conventional 1,400 m warm-up and a 700 m conventional warm-up that integrated tubing-assisted (TA), paddle (PD), or squat (SQ) warm-ups) over four separate days.
Prevalence of transthyretin cardiac amyloidosis in patients with aortic stenosis.

Prince Sultan Cardiac Centre, Heart Function Unit, Department of Adult Cardiology Riyadh, Saudi Arabia.
Background: Transthyretin cardiac amyloidosis (ATTRCA) is a prevalent disease, and it can be associated with heart failure (HF), left ventricle hypertrophy (LVH), atrial fibrillation (AF), and aortic stenosis (AS).
Aim: The study aims to detect the prevalence of ATTRCA in the symptomatic AS population.
Method: A single-center prospective study screening for ATTRCA in patients diagnosed with symptomatic severe AS undergoing aortic valve (AV) intervention.
