BACKGROUND: Identification of lobar spontaneous intracerebral haemorrhage associated with cerebral amyloid angiopathy (CAA) is important because it is associated with a higher risk of recurrent intracerebral haemorrhage than arteriolosclerosis-associated intracerebral haemorrhage. We aimed to develop a prediction model for the identification of CAA-associated lobar intracerebral haemorrhage using CT features and genotype. METHODS: We identified adults with first-ever intracerebral haemorrhage diagnosed by CT, who died and underwent research autopsy as part of the Lothian IntraCerebral Haemorrhage, Pathology, Imaging and Neurological Outcome (LINCHPIN) study, a prospective, population-based, inception cohort...

White matter hyperintensities (WMH) have been linked to cognitive dysfunction and dementia, although the reasons are unclear. One possibility is that WMH promote neurodegeneration, which, in turn, affects cognition. We examined whether cortical thickness, a marker of neurodegeneration, mediates the relationship between WMH and cognition among 519 older adults. Using conditional process analysis modeling techniques, we examined the association between WMH volume and global cognition and tested whether cortical thickness mediates this relationship statistically...

This study investigated for the first time brain ischemic involvement in 19 consecutive neurologically asymptomatic PNH patients by non-enhanced cerebral MRI, and by intracranial arterial and venous angio-MRI. Eleven cases (58%, 7 aged <65) showed pathological findings: 9 white matter (WM) abnormalities related to chronic ischemic small vessel disease, 2 a focal abnormality >5 mm, and 5 cases a score >4 by the age-related white matter changes (ARWMC) scale. Compared with age and sex-matched controls (1:2 ratio), patients showed an increased frequency of periventricular WM vascular degeneration (32% versus 5...

The pauci-immune crescentic glomerulonephritis (PICGN) is generally associated with small-vessel vasculitis with a few reported cases associated with other autoimmune diseases such as Systemic Lupus Erythematosus (SLE). We present the case of a female 34-year-old patient with acute kidney injury symptoms with indication for renal replacement therapy in the context of clinical SLE diagnosis. A kidney biopsy was conducted and it was found that most glomeruli showed some segmental sclerosis with synechia to the Bowman's capsule...

BACKGROUND: Psoriasis is a chronic inflammatory disease. Pustular, erythrodermic, and extensive plaque psoriasis are responsible for systemic complications. Systemic capillary leak syndrome is the complication with greater progression to death and occurs due to vascular changes. PURPOSE: The aim of this study was to evaluate vascular changes through the expression of CD34 and ICAM-1 in plaque, pustular, and erythrodermic psoriasis. METHODS: The sample consisted of seven patients with erythrodermic psoriasis, 24 with moderate-severe plaque psoriasis, 14 with mild plaque psoriasis and 13 with pustular psoriasis...

Vascular structures of skin are important biomarkers in diagnosis and assessment of cutaneous conditions. Presence and distribution of lesional vessels are associated with specific abnormalities. Therefore, detection and localization of cutaneous vessels provide critical information towards diagnosis and stage status of diseases. However, cutaneous vessels are highly variable in shape, size, color and architecture, which complicate the detection task. Considering the large variability of these structures, conventional vessel detection techniques lack the generalizability to detect different vessel types and require separate algorithms to be designed for each type...

BACKGROUND/AIMS: Pathogenetic mechanisms involved in enlargement of basal ganglia perivascular spaces (BG-PVSs) are controversial. Here, we assessed whether pulsatile or steady components of blood pressure (BP) are associated with enlarged BG-PVS. METHODS: We evaluated the association between BG-PVS and pulsatile and steady components of BP in Atahualpa residents aged ≥60 years, by the use of regression models and receiver operator characteristics (ROC) curve analysis, after taking into account the effect of demographics, cardiovascular risk factors, and other signatures of cerebral small vessel disease (SVD)...

REVIEW
Milton Packer
A primary goal of the treatment of type 2 mellitus is the prevention of morbidity and mortality due to cardiovascular disease. However, antihyperglycemic drugs have the capacity to cause deleterious effects on the circulation, a risk that is not adequately reflected by the endpoints selected for emphasis in large-scale clinical trials that are designed to evaluate cardiovascular safety. The primary endpoint of the large-scale studies mandated by regulatory authorities focuses only on 3-4 events that depict only a limited view of the circulatory system...

Hereditary Haemorrhagic Telangiectasia, also known as Osler-Rendu-Weber disease is a rare autosomal dominant disorder affecting small vessels of multiple systems whose main pathological change is the presence of abnormal arteriovenous communications. Usually presents as skin and mucosal telangiectasias, epistaxis, gastrointestinal bleeding and visceral arteriovenous malformations. Although the epistaxis and gastrointestinal blood loss can result in anaemia, patients with hereditary haemorrhagic telangiectasia rarely presents as severe anaemia1 or CNS infections...

BACKGROUND AND PURPOSE: The genetic contribution to dilated perivascular space (dPVS) burden-an emerging MRI marker of cerebral small vessel disease-is unknown. We measured the heritability of dPVS burden and its shared heritability with other MRI markers of cerebral small vessel disease. METHODS: The study sample comprised 1597 participants from the population-based Three City (3C) Dijon Study, with brain MRI and genome-wide genotyping (mean age, 72.8±4.1 years; 61% women)...

Alzheimer's disease (AD) is the most common cause of cognitive dysfunction in older adults. The pathological hallmarks of AD such as beta amyloid (Aβ) aggregation and neurometabolic change, as indicated by altered myo-inositol (mI) and N-acetylaspartate (NAA) levels, typically precede the onset of cognitive dysfunction by years. Furthermore, cerebrovascular disease occurs early in AD, but the interplay between vascular and neurometabolic brain change is largely unknown. Thirty cognitively normal older adults (age = 70 ± 5...

Cyclooxygenase-2 (COX-2) derived-prostanoids participate in the altered vascular function and mechanical properties in cardiovascular diseases. We investigated whether regulator of calcineurin 1 (Rcan1) participates in vascular contractility and stiffness through the regulation of COX-2. For this, wild type (Rcan1+/+) and Rcan1-deficient (Rcan1-/-) mice untreated or treated with the COX-2 inhibitor rofecoxib were used. Vascular function and structure were analysed by myography. COX-2 and phospo-p65 expression were studied by western blotting and immunohistochemistry and TXA2 production by ELISA...

OBJECTIVES: Cerebral white matter lesions (WMLs) are regarded to be subclinical ischemic changes of the cerebral parenchyma. Many previous studies have shown that baseline blood pressure (BP) is one of the most important factors for WMLs, but the relation between exercise BP and WMLs has not been fully evaluated. So, we sought to investigate the relationships between cerebral WMLs and peak exercise BP. METHODS: Brain magnetic resonance imaging scan and treadmill testing were performed simultaneously in 130 consecutive subjects without history of stroke or transient ischemic stroke...

BACKGROUND: The role of nonobstructive (<50% stenosis) carotid atherosclerosis (NOCA) in young adults with ischemic stroke is not well understood. In the present study, we investigated the prevalence and the ultrasonic characteristics of NOCA in a consecutive series of young adults with cryptogenic stroke (CS). METHODS: Patients aged 18-54, consecutively treated in a tertiary hospital for first-ever CS (defined as an ischemic stroke without ASCOD (A: atherosclerosis; S: small-vessel disease; C: cardiac pathology; O: other causes) grade 1 potential cause) in the carotid artery territory, were prospectively enrolled...

BACKGROUND: Unrecognized myocardial infarction (MI) is a frequent condition with unknown underlying reason. We hypothesized the lack of recognition of MI is related to pathophysiology, specifically differences in underlying small and large vessel disease. METHODS: 6128 participants were examined with retinal photography, ultrasound of the carotid artery and a 12‑lead electrocardiography (ECG). Small vessel disease was defined as narrower retinal arterioles and/or wider retinal venules measured on retinal photographs...
