BACKGROUND: The brain's cholinergic network has various interconnections with the cortical and subcortical structures. Disruption of cholinergic pathways by white matter hyperintensities (WMH) may cause pathologic changes within brain regions. Thus, WMH may represent an important pathological contributor of subcortical vascular cognitive impairment (scVCI). We aim to investigate associations between the magnitude of WMH and volumetric changes in cortical and subcortical regions innervated by cholinergic neurons in patients with scVCI...

Wu et al wrote an interesting manuscript that elaborates about a burning clinical question. (1) The study design contains a large population to address their man question: if non-HDL-C level is associated with prevalence of asymptomatic vulnerable carotid atherosclerotic plaque. Particularly the latter, collecting such a large population with asymptomatic patients with a vulnerable plaque, deservers credits. The most important question I had reading this important paper is how exactly the vulnerability of the (asymptomatic) plaque was defined...

BACKGROUND AND AIMS: Subclinical atrial fibrillation (AF) is known to underlie a number of cases of cryptogenic stroke (CrS). However there is need to define the most effective strategy for AF detection. We analyzed the diagnostic usefulness of a strategy based on ultra-early continuous monitoring in patients with CrS in terms of AF detection, oral anticoagulation treatment and stroke recurrence, in comparison to a standard outpatient strategy. METHODS: Patients with ischemic stroke of undetermined origin and confirmed to be cryptogenic after extensive work-up were searched for AF with: a) a conventional strategy (historical cohort, n=101) with serial ECGs and 24h-Holter monitoring; or b) an ultra-early monitoring strategy with insertable cardiac monitor (ICM) implanted before discharge (prospective cohort, n=90)...
