Dihydropyridine calcium channel blockers may possess antioxidant properties, and might improve micro and macrovascular structure and function. Combination treatment with an ACE inhibitor may have additional advantages, compared with a thiazide diuretic. The aim of the present study is to investigate the effects of a short-term treatment with lercanidipine, and to compare two combination treatments: lercanidipine + enalapril vs. lercanidipine + hydrochlorothiazide on structural alterations in retinal arterioles, on skin capillary density and on large artery distensibility...

BACKGROUND: Varices and venous insufficiency are common and serious health problems in the general population which affect quality of life. Endothermal treatment of the great saphenous vein has become the first line of treatment for superficial venous reflux, and the endovenous laser ablation (EVLA) method has been widely accepted all over the world. In this method, ablation is provided by a laser fiber inserted into the lumen of the vein. Initially, the fibers were 810 nm, but today the fibers are usually 940, 980, or 1470 nm...

BACKGROUND: Musculoskeletal findings in Sjögren's syndrome are arthralgia, arthritis, myalgia, myositis, fibromyalgia, and chronic fatigue. Enthesis zones are important in the formation of pain in the musculoskeletal system. Musculoskeletal ultrasound (US) may show subclinical enthesitis in the synovial joints and in the axial skeleton before joint swelling in inflammatory diseases characterized by arthritis. OBJECTIVE: In this study, we aimed to determine the presence of enthesopathy using the Madrid sonographic enthesitis index (MASEI) in patients with primary Sjögren's syndrome (PSS)...

INTRODUCTION: Mental stress-induced ischemia approximately doubles the risk of cardiac events in patients with coronary artery disease, yet the mechanisms underlying changes in coronary blood flow in response to mental stress are poorly characterized. Neuronal nitric oxide synthase (nNOS) regulates basal coronary blood flow in healthy humans and mediates mental stress-induced vasodilation in the forearm. However, its possible role in mental-stress-induced increases in coronary blood flow is unknown...

Early recognition of joint inflammation will increase treatment efficacy in rheumatoid arthritis (RA). Yet, conventional power Doppler (PD) ultrasound might not be sufficiently sensitive to detect minor inflammation. We investigated the sensitivity of high-frame rate Doppler, combined with singular value decomposition technique, to suppress tissue signals, for microvascular flow in a flow phantom setup and in a proof-of-principle study in healthy controls and in RA patients with different disease activities...

Diastolic dysfunction is a sensitive early indicator of heart failure and can provide additional data to conventional measures of systolic function. Transmitral Doppler ultrasound, which measures the one-dimensional flow of blood through the mitral valve, is currently the preferred method for the measurement of diastolic function, but the measurement of the left ventricular volume changes using high-temporal-resolution cinematic magnetic resonance imaging (CINE MRI) is an alternative approach which is emerging as a potentially more robust and user-independent technique...

The neurovascular coupling response has been defined for the adult brain but in the neonate non-invasive measurement of local cerebral perfusion using NIRS or BOLD fMRI have yielded variable and inconsistent results, including negative responses suggesting decreased perfusion and localised tissue tissue hypoxia. Also, the impact of permissive hypercapnia (Pa CO2  > 50 mmHg) in the management of neonates on cerebrovascular responses to somatosensory input is unknown. Using NIRS to measure changes in cerebral oxy- and deoxy-haemoglobin (ΔoxyHb, ΔdeoxyHb) in 8 anaesthetised newborn lambs, we studied the cerebral haemodynamic functional response to left median nerve stimulation using stimulus trains of 1...

BACKGROUND: Diabetic peripheral neuropathy (DPN) is a common complication of Type 2 diabetes (T2D). Apart from hyperglycemia, its pathogenesis is poorly understood. Apolipoprotein-CIII (apoC-III) associated with triglyceride metabolism, is a risk factor for cardiovascular disease. Its role in DPN is not well-established. We studied the associations of apoC-III, endothelial function and DPN. METHODS: In patients with T2D, anthropometric data, fasting blood, and urine were collected for biochemistry and urine albumin/creatinine measurements (uACR)...
