Objectives: The incidence of thromboembolism in patients with SLE is higher than that in the general population. HCQ, widely used to treat lupus, may have vascular protective effects. The aim of this study was to determine whether long-term HCQ exposure is associated with decreased thromboembolism risk in SLE. Methods: We designed a prospective cohort study within an SLE population based on the National Health Insurance Research Database in Taiwan. We divided participants into HCQ and control groups according to HCQ prescription during the first year...

Introduction. It is estimated up to 6 % of prosthetic vascular grafts become infected. Staphylococcus aureus is predominant in early infection and coagulase-negative staphylococci are predominant in late infections. Enterobacteriaceae cause 14-40 % of prosthetic vascular graft infections. This is, to our knowledge the first reported case of Salmonella gastroenteritis causing chronic prosthetic vascular graft infection (PVGI). Case presentation. A 57 years old lady presented with signs and symptoms of prosthetic vascular graft infection...

REVIEW
Natalie Ly Ngu, Mark McEvoy
BACKGROUND AND AIMS: Despite worldwide reductions in active smoking, non-smokers continue to be exposed to environmental tobacco smoke, especially at home or workplace. There is a well-recognised association between active smoking and peripheral arterial disease, however, a relationship to environmental tobacco smoke exposure is less substantiated. The aims of this paper are to review the literature regarding the association between environmental tobacco smoke and peripheral arterial disease and identify the public health implications of the findings...

Autologous cell therapy represents a novel treatment option for vascular regeneration in different disease conditions. Both experimental and clinical studies indicate a therapeutic potential for different proangiogenic cells (PCs), including endothelial progenitor cells (EPCs) in the treatment of peripheral artery disease. A significant improvement of ischemic symptoms has been reported in different trials evaluating PCs for the treatment of critical limb ischemia. However, contrasting results from different meta-analyses question the efficacy of PC-based approaches on long-term outcomes, including amputation and survival...

BACKGROUND: Hypertension is a prominent preventable cause of premature morbidity and mortality. People with hypertension and established cardiovascular disease are at particularly high risk, so reducing blood pressure below standard targets may be beneficial. This strategy could reduce cardiovascular mortality and morbidity but could also increase adverse events. The optimal blood pressure target in people with hypertension and established cardiovascular disease remains unknown. OBJECTIVES: To determine if 'lower' blood pressure targets (≤ 135/85 mmHg) are associated with reduction in mortality and morbidity as compared with 'standard' blood pressure targets (≤ 140 to 160/ 90 to 100 mmHg) in the treatment of people with hypertension and a history of cardiovascular disease (myocardial infarction, angina, stroke, peripheral vascular occlusive disease)...

BACKGROUND: Osteoprotegerin (OPG) is a potential biomarker for severity and complications of cardiovascular diseases. Peripheral arterial disease (PAD) is associated with an increased risk of death in kidney transplantation (KT) patients. This prospective cross-sectional study evaluated the relationship between serum OPG and PAD in KT patients. METHODS: Seventy-four KT patients were enrolled for this PAD study. Fasting blood samples were obtained to measure serum OPG levels by using enzyme-linked immunosorbent assay kits...

Perivascular spaces play a pivotal role in the exchange between cerebrospinal and interstitial fluids, and in the clearance of waste in the CNS, yet their precise anatomical components are not well described. The aim of this study was to characterise the ultrastructure of perivascular spaces and their role in the transport of fluid, in the spinal cord of healthy rats, using transmission electron microscopy. The distribution of cerebrospinal fluid tracers injected into the subarachnoid space was studied using light, confocal and electron microscopy...

OBJECTIVE: Readmission rates are known to be high for vascular surgery patients in general, but there are limited data describing the risk of surgical and nonsurgical readmission among patients with diabetic foot ulcers (DFUs). Our aim was to identify factors associated with unplanned readmission in DFU patients treated in a multidisciplinary setting. METHODS: We studied a single-center cohort of patients enrolled in a multidisciplinary diabetic foot service (July 2012-June 2017)...

BACKGROUND: The remarkable success of clinical trials in mineralocorticoid receptor (MR) inhibition in heart failure has driven research on the physiological and pathological role(s) of nonepithelial MR expression. MR is widely expressed in the cardiovascular system and is a major determinant of endothelial function, smooth muscle tone, vascular remodeling, fibrosis, and blood pressure. An important new dimension is the appreciation of the role MR plays in immune cells and target organ damage in the heart, kidney and vasculature, and in the development of insulin resistance...

A 56-year-old middle-eastern male with a long-standing history of poorly controlled type 2 diabetes mellitus presented to us complaining of severely painful bilateral upper and lower extremity cramps occurring shortly after his rapid-acting insulin analog injection(s). The cramps had started 6 months ago and have been occurring intermittently in non-predictable episodes since then. He had otherwise never experienced any insulin-related adverse reaction(s) before. His cramps are very painful and debilitating, interfering with his daily activities and placing him in a state of constant fear/anxiety of re-experiencing them...

Advancing age is the top risk factor for the development of neurodegenerative disorders, including Alzheimer's disease (AD). However, the contribution of aging processes to AD etiology remains unclear. Emerging evidence shows that reduced brain metabolic and vascular functions occur decades before the onset of cognitive impairments, and these reductions are highly associated with low-grade, chronic inflammation developed in the brain over time. Interestingly, recent findings suggest that the gut microbiota may also play a critical role in modulating immune responses in the brain via the brain-gut axis...

Synopsis Claudication from peripheral artery disease (PAD) may mimic or coexist with musculoskeletal conditions and represents an important diagnostic consideration in patients over 50. Physical therapists are optimally positioned to recognize this condition by incorporating a vascular history and physical examination in appropriately selected patients. Recognition of PAD is important both from the standpoint of addressing the ischemic risk to the limb and because PAD associated with high cerebrovascular and cardiovascular risk...

BACKGROUND: Type-2 diabetes mellitus accounts for 80-90% of diabetic patients. So far, the treatment of diabetes mainly aims at elevating insulin level and lowering glucose level in the peripheral blood and mitigating insulin resistance. Physiologically, insulin secretion from pancreatic β cells is delicately regulated. Thus, how insulin-related therapies could titrate blood glucose appropriately and avoid the occurrence of hypoglycemia remains an important issue for decades. Similar question is addressed on how to attenuate vascular complication in diabetic subjects...

RATIONALE: The role of hypertension in cerebral small vessel disease is poorly understood. At the base of the brain (the 'vascular centrencephalon'), short straight arteries transmit blood pressure directly to small resistance vessels; the cerebral convexity is supplied by long arteries with many branches, resulting in a drop in blood pressure. Hypertensive small vessel disease (lipohyalinosis) causes the classically described lacunar infarctions at the base of the brain; however, periventricular white matter intensities (WMIs) seen on MRI and WMI in subcortical areas over the convexity, which are often also called 'lacunes', probably have different aetiologies...

BACKGROUND AND AIMS: The rapidly growing discipline of lipidomics allows the study of a wide spectrum of lipid species in body fluids and provides new insights into the pathogenesis of cardiovascular disease. We investigated serum phosphatidylcholine (PC) and lysophosphatidylcholine (lysoPC) species in relation to arterial stiffness, hemodynamics, and endothelial dysfunction in symptomatic patients with atherosclerosis and in healthy controls. METHODS AND RESULTS: Thirty-two patients with peripheral arterial disease (age 61...

PURPOSE OF REVIEW: To review recent literature pertaining to sickle cell retinopathy (SCR) and, in particular, sickle cell maculopathy. RECENT FINDINGS: Several recent studies suggest that macular perfusion abnormalities seen in patients with sickle cell disease of various genotypes may affect both the superficial and deep capillary plexi, with a predilection for the deep capillary plexus. Further, these changes may be associated with areas of macular thinning, as well as with peripheral retinal ischemia, even in individuals without visual symptoms, contrary to what has previously been described in both diabetic retinopathy and retinal vein occlusion...

Background -Nitric oxide signaling plays a key role in regulation of vascular tone and platelet activation. Here, we seek to understand the impact of a genetic predisposition to enhanced nitric oxide signaling on risk for cardiovascular diseases, thus informing the potential utility of pharmacologic stimulation of the nitric oxide pathway as a therapeutic strategy. Methods -We analyzed the association of common and rare genetic variants in two genes that mediate nitric oxide signaling [Nitric Oxide Synthase 3 (NOS3) and Guanylate Cyclase 1, Soluble, Alpha 3 (GUCY1A3)] with a range of human phenotypes...

OBJECTIVES: Systemic sclerosis (SSc) is a rare, autoimmune disease characterised by endothelial dysfunction, which is associated with peripheral vasculopathy, such as digital ulcers (DU). We sought to determine if acute oral administration of tetrahydrobiopterin (BH4), an essential cofactor for endothelial nitric oxide synthase, would augment endothelial function in patients with SSc. METHODS: Twelve SSc patients, of whom a majority had a history of DU, were studied 5 hours after oral BH4 administration (10 mg/kg body mass) or placebo on separate days using controlled, counterbalanced, double-blind, crossover experimental design...

Black patients have a higher prevalence of peripheral artery disease (PAD) than white patients, and also tend to have a greater extent and severity of disease, and poorer outcomes. The association of race with quality of health (QOH) after peripheral vascular intervention (PVI), however, is less well-known. In our study, we hypothesized that after PVI, black patients experience worse QOH than white patients. We retrospectively assessed racial differences in health status using responses to the Peripheral Arterial Questionnaire (PAQ) at baseline (pre-PVI) and up to 6 months following PVI among 387 patients...
