Background The use of aspirin for primary prevention of cardiovascular events in men and women remains controversial. Our study aimed to investigate the role of aspirin in primary stroke prevention in men and women and the effect of aspirin on risk of ischemic stroke in patients with covert cerebral small vessel disease (ccSVD). Methods We perform...
Article
Rationale Direct oral anticoagulants (DOAC) are highly effective in preventing ischaemic strokes in people with atrial fibrillation (AF). However, it is unclear how soon they should be started after acute ischaemic stroke (AIS). Early initiation may reduce early risk of recurrence but might increase the risk of haemorrhagic complications. Aim To e...

Pregnancy, postpartum and menopause are regarded as periods women are more vulnerable to ischaemic events. There are conflicting results regarding stroke risk and hormone replacement therapy (HRT) during menopause. Stroke in pregnancy is generally increasing with serious consequences for mother and child; therefore, recommendations for acute treatm...

Background: An increased prevalence of Parkinson's disease (PD) disease has been previously reported in subjects with Fabry disease (FD) carrying alpha-galactosidase (GLA) mutations and their first-line relatives. Moreover, decreased alpha-galactosidase A (AGLA) enzymatic activity has been reported among cases with PD compared to controls. Object...
Article
Introduction: Atrial fibrillation (AF) is one of the leading causes of ischaemic stroke. However, screening for AF is often time-consuming in clinical practice. Therefore, the determination of an appropriate marker to detect the presence of AF would improve the diagnostic process. Objective: The aim of the current study was to evaluate the effic...

Vertebral haemangioma is a benign vascular tumour mostly seen in the thoracic region of the spine. Spinal haemangiomas are usually asymptomatic and are discovered incidentally. In a few patients, however, aggressive vertebral haemangiomas can cause local pain, radicular pain or neurologic deficits, which result from neural compression. The aetiolog...

Introduction: Recently, it has been shown in animal models that there is a variability in X-chromosome inactivation. Thus, in some brains a mother’s X chromosome may dominate to one hemisphere and the father’s dominate to the other one. Hence, response of brain to ischemia may differ in men and women. Our goal was to determine if there are differen...
