Background: Sparse information regarding the long-term risk of acute myocardial infarction (MI) following a transient ischemic attack (TIA) emphasizes further research to guide preventive strategies and risk stratification in patients with a TIA.
Methods: We conducted a nationwide cohort study to investigate the 5-year risk of MI and all-cause mortality in patients with a first-time TIA. Patients with a first-time TIA were identified in the Danish Stroke Registry (2013-2020), matched on age, sex, and calendar year (1:4) with the general population and (1:1) with patients with first-time ischemic stroke.
Objectives: To calculate a polygenic risk score (PRS) based on single nucleotide variants (SNVs) previously associated with primary Sjögren's disease (SjD) with genome-wide significance, and determine the genetic risk for SjD stratified by antibodies, sex and age at diagnosis.
Methods: Patients with SjD (n = 1065) were genotyped using Illumina OmniExpressExome chip. Control genotype data were available (n = 7742).
Introduction: Patients with pulmonary embolism (PE) experience impaired functional ability and reduced quality of life long after discharge from the hospital. However, there are no structured follow-up programmes in Denmark for these patients, and there is considerable variation in practice patterns of post-PE management. No studies have investigated the effectiveness of structured follow-up care models in patients with PE.

- A nationwide study in Denmark from 2010 to 2020 analyzed the relationship between socioeconomic status (SES) and poststroke dementia (PSD) among stroke patients, focusing on income, education, and employment.
- The study included 98,489 patients and found that those with low SES had significantly higher rates of PSD, with low income linked to a 1.24 times increase, low education to a 1.11 times increase, and unemployment to a 1.57 times increase in dementia rates.
- Disparities were more pronounced in certain groups, notably women, immigrants, and patients younger than 70, indicating that socioeconomic factors play a crucial role in long-term stroke outcomes beyond typical risk factors.
