Effects of population-based screening for atrial fibrillation on quality of life.

Background: Screening for atrial fibrillation is rising and may worsen or improve quality of life.

Methods: We assessed quality of life (EQ-5D-5L) data in 6,004 participants with stroke risk factors randomised to usual care (n=4,503) or implantable loop recorder with anticoagulation upon detection of atrial fibrillation (n=1,501). Five domains (mobility, selfcare, usual activities, pain/discomfort, anxiety/depression) each scored from one to five were calculated into individual index scores (worst=-0.

Point of view: Challenges in implementation of new immunotherapies for Alzheimer's disease.

The advancement of disease-modifying treatments (DMTs) for Alzheimer's disease (AD), along with the approval of three amyloid-targeting therapies in the US and several other countries, represents a significant development in the treatment landscape, offering new hope for addressing this once untreatable chronic progressive disease. However, significant challenges persist that could impede the successful integration of this class of drugs into clinical practice. These challenges include determining patient eligibility, appropriate use of diagnostic tools and genetic testing in patient care pathways, effective detection and monitoring of side effects, and improving the healthcare system's readiness by engaging both primary care and dementia specialists.

Dual-ligand fluorescence microscopy enables chronological and spatial histological assignment of distinct amyloid-β deposits.

Different types of deposits comprised of amyloid-β (Aβ) peptides are one of the pathological hallmarks of Alzheimer's disease (AD) and novel methods that enable identification of a diversity of Aβ deposits during the AD continuum are essential for understanding the role of these aggregates during the pathogenesis. Herein, different combinations of five fluorescent thiophene-based ligands were used for detection of Aβ deposits in brain tissue sections from transgenic mouse models with aggregated Aβ pathology, as well as brain tissue sections from patients affected by sporadic or dominantly inherited AD. When analyzing the sections with fluorescence microscopy, distinct ligand staining patterns related to the transgenic mouse model or to the age of the mice were observed.
