OBJECTIVES: Iliofemoral arteries have been the preferred access for transcatheter aortic valve replacement (TAVR). When these arteries are too small, calcified or tortuous, an alternative access must be considered. Transinnominate (TI) access is an extrathoracic approach that does not require manipulation of major neurovascular structures or the apex. The aim of this study is to evaluate the efficacy and safety of TI TAVR as an alternative access in patients with severe aortic stenosis not amenable to a transfemoral approach...

BACKGROUND: Cerebral small vessel disease (SVD) can cause cognitive impairment, disability, and dementia. While it's still unclear about the pathogenesis of SVD, several risk factors of SVD have been identified, and studies suggested that hypertension may play a critical role in SVD. Furthermore, studies have demonstrated that CYP2J2 isoform, 50 G>T variant, is associated with increase the risk of ischemic stroke. Thus, we hypothesized that CYP2J2 50 G>T variant is associated with increased risk of cerebral SVD...

ANCA-associated vasculitis (AAV) is characterized by inflammation and destruction of small and medium-sized vessels. Current management strategies for AAV have been validated in large groups of patients. However, recent insights indicate that distinct patient subsets may actually exist within AAV, thereby justifying the development of more personalized treatment strategies. In this review, we discuss current evidence for a better classification of AAV based on ANCA type. We describe how thus defined categories of AAV patients may differ in genetic background, clinical presentation, immune pathology, response to treatment and disease outcome...

Background: More than 70 million Vietnamese rely on small-scale farming for some form of household income. Water on many of those farms is contaminated with waste, including animal manure, partly due to non-sustainable waste management. This increases the risk of water-related zoonotic disease transmission. The purpose of this research was to examine the impact of various demographic and management factors on the likelihood of finding Escherichia coli in drinking water sourced from wells and rainwater on farms in Vietnam...

Granulomatosis with polyangiitis (GPA) often causes small blood vessel lesions in multiple organs, with less impact on large vessels. We report a case involving not only large blood vessels, but also angina. The computed tomographic angiography of large vessels and vascular ultrasonography of the extremity also suggested great arteries of the body were involved. Further cytoplasmic antineutrophil cytoplasmic antibody tests, pathological examination and dynamic chest computed tomography scan confirmed the diagnosis of GPA...

We investigated the frequency and clinical significance of diagonal earlobe crease (DELC) in cognitively impaired patients using imaging biomarkers, such as white matter hyperintensities (WMH) on MRI and amyloid-β (Aβ) PET. A total of 471 cognitively impaired patients and 243 cognitively normal (CN) individuals were included in this study. Compared with CN individuals, cognitively impaired patients had a greater frequency of DELC (OR 1.6, 95% CI 1.1-2.2, P = 0.007). This relationship was more prominent in patients with dementia (OR 1...

BACKGROUND: Systemic sclerosis is a multisystem disorder characterized by microangiopathy, dysregulation of the immune system and massive deposition of collagen in the connective tissue of the skin, blood vessels and various internal organs. Although the mortality from renal crises has dropped significantly due to the use of angiotensin-converting enzyme inhibitors, cardiac and pulmonary involvement accounts for significant morbidity and mortality. We studied 28 patients with systemic sclerosis at Gandhi Medical College and Hospital, Hyderabad, over a period of two years for cardiopulmonary involvement...

Objective We explored the association between the total small vessel disease (SVD) score obtained with magnetic resonance imaging and risk factors and outcomes in the Japanese population. Methods The presence of SVD features, including lacunes, cerebral microbleeds, white matter changes, and basal ganglia perivascular spaces on MRI, was summed to obtain a "total SVD score" (range 0-4). Ordinal and multinomial logistic regression analyses were performed to investigate the association of higher total SVD scores with vascular risk factors, the Mini Mental State Examination (MMSE) score, and cerebral atrophy...

Monogenic autoinflammatory syndromes are a rare group of disorders characterized by periodic episodes of systemic inflammation of endogenous origin. Sometimes, these diseases may present with features akin to vasculitis. We conducted a literature review on such vasculitic manifestations in described monogenic autoinflammatory syndromes utilizing the Online Mendelian Inheritance in Man (OMIM), Medline, and Scopus databases. Our search identified that Familial Mediterranean fever (FMF) can manifest with features of either small, medium, large, or variable-vessel vasculitis...

INTRODUCTION: Assessing disease activity in patients suffering from autoimmune diseases is complex. Symptoms are multiple, often subjective and there are no reliable biomarkers. Many activity scores have been implemented to compare treatment efficacy in clinical trials. Their use in clinical practice is largely unknown. We performed a practical survey to analyze the use of activity scores in clinical practice to consider treatment response and to assess the determinants of their use. METHODS: A sample of French internists answered a questionnaire about activity scores of systemic lupus erythematosus, Sjögren's syndrome, autoimmune myositis and necrotizing vasculitis of small vessels...

Background Patients with cerebral small vessel disease may suffer from varying levels of cognitive deficit and may progress on to vascular dementia. The extent of involvement, as seen on conventional magnetic resonance (MR) measures, correlates poorly with the level of cognitive decline. The purpose of this study was to investigate the utility of diffusion tensor imaging (DTI) as a marker for white matter damage in small vessel disease and to assess its correlation with cognitive function. Methods Thirty consecutive patients with cerebral small vessel disease underwent conventional MR imaging, DTI, and neuropsychological assessment...

REVIEW
Santiago Martinez Sosa, Kenneth J Smith
The deep and periventricular white matter is preferentially affected in several neurological disorders, including cerebral small vessel disease (SVD) and multiple sclerosis (MS), suggesting that common pathogenic mechanisms may be involved in this injury. Here we consider the potential pathogenic role of tissue hypoxia in lesion development, arising partly from the vascular anatomy of the affected white matter. Specifically, these regions are supplied by a sparse vasculature fed by long, narrow end arteries/arterioles that are vulnerable to oxygen desaturation if perfusion is reduced (as in SVD, MS and diabetes) or if the surrounding tissue is hypoxic (as in MS, at least)...
