Alcohol Consumption and Cerebral Small- and Large-Vessel Diseases: A Mendelian Randomization Analysis
CONCLUSIONS: Our findings suggest a positive association of alcohol consumption with risk of cerebral SVDs and its inverse association with risk of large-vessel disease through intermediaries, such as hypertension or low-density lipoprotein cholesterol. These findings provide insight into potential causal mechanisms linking alcohol consumption with stroke risk.PMID:37612092 | DOI:10.5551/jat.64222

Association of chocolate consumption with neurological and cardiovascular outcomes in atrial fibrillation: data from two Swiss atrial fibrillation cohort studies (Swiss-AF and BEAT-AF)
CONCLUSION: While chocolate consumption was not associated with MRI findings and major adverse cardiac events in an atrial fibrillation population, No/Low-Ch was associated with a lower cognitive construct score, higher risk of heart failure hospitalisation and increased all-cause mortality compared to Mod-Ch.CLINICALTRIALS: gov Identifier: NCT02105844.PMID:37609948 | DOI:10.57187/smw.2023.40109

Consensus statement for the management of incidentally found brain white matter hyperintensities in general medical practice
Med J Aust. 2023 Aug 21. doi: 10.5694/mja2.52079. Online ahead of print.ABSTRACTINTRODUCTION: There is a paradigm shift in our understanding of white matter hyperintensities (WMH) found on brain imaging. They were once thought to be a normal phenomenon of ageing and, therefore, warranted no further investigation. However, evidence now suggests these lesions are markers of poor brain and cardiovascular health, portending an increased risk of stroke, cognitive decline, depression and death. Nevertheless, no specific guidelines exist for the management of incidentally found WMH for general medical practitioners and other clin...

Correlation of the middle cerebral artery atherosclerotic plaque characteristics with ischemic stroke recurrence: a vessel wall magnetic resonance imaging study
This study aims to analyze the imaging features of atherosclerotic plaques in the middle cerebral artery (MCA) of patients with recurrent ischemic stroke using vessel wall magnetic resonance imaging (VWMRI) and investigate the correlation between these imaging features and the recurrence of ischemic stroke. Consecutive patients with ischemic stroke caused by atherosclerotic stenosis of the MCA were collected. The patients were divided into recurrent and non-recurrent ischemic stroke groups. We obtained VWMRI images of MCA plaques using 3.0T MRI by black-blood sequences, and the differences in VWMRI characteristics and clin...

Perivascular spaces mediate a relationship between diabetes and other cerebral small vessel disease markers in cerebrovascular and neurodegenerative diseases
Cerebral small vessel disease (SVD) is used to describe heterogeneous pathological changes in perforating arterioles, venules, and capillaries that supply blood to subcortical structures.1 These pathological changes manifest on magnetic resonance imaging (MRI) as quantifiable volumetric measures. Established markers of SVD identified on MRI include deep white matter hyperintensities (dWMH) and periventricular white matter hyperintensities (pWMH) of presumed vascular origin and lacunes, and MRI visible enlarged perivascular spaces (PVS) in the white matter (wmPVS) or basal ganglia (bgPVS).

Biliverdin reductase B is a plasma biomarker for intraplaque hemorrhage and a predictor of ischemic stroke in symptomatic carotid stenosis
Background and Aims: Intraplaque hemorrhage (IPH) is a hallmark of atherosclerotic plaque instability. Biliverdin reductase B (BLVRB) is enriched in plasma and plaques from patients with symptomatic carotid atherosclerosis and functionally associated with plaque IPH. We explored the biomarker potential of plasma BLVRB through 1) its correlation with IPH in carotid plaques assessed by magnetic resonance imaging (MRI) and with recurrent ischemic stroke; and 2) its use for monitoring pharmacotherapy targeting IPH in a preclinical setting.

Secondary neurodegeneration of ipsilateral substantia nigra in acute ischemic stroke
ConclusionsA better understanding of the secondary degeneration of the substantia nigra has the potentiality to offer a chance for neuroprotection in acute stroke, but further studies are needed.

Low-dose intravenous recombinant tissue plasminogen activator in acute ischemic stroke without large vessel occlusion screened by 3T MRI
CONCLUSIONS: Our study indicates the efficacy and safety of low-dose rTPA treatment for AIS without LVO within 4.5 hours. Patient selection for rTPA by 3T MRI decreased complications and mortality.PMID:37522667 | DOI:10.26355/eurrev_202307_33126
