One Step Back from Bedside to the Bench-How Do Different Arterial Stiffness Parameters Behave in Relation to Peripheral Resistance?

The investigation of arterial stiffening is a promising approach to estimating cardiovascular risk. Despite the widespread use of different methods, the dynamic nature of measured and calculated stiffness parameters is marginally investigated. We aimed to determine the stability of large artery elasticity parameters assessed via commonly used, ultrasound-based and oscillometric methods in relation to peripheral resistance modulation.

Impaired decision-making in borderline personality disorder.

Introduction: Borderline personality disorder (BPD) is a complex mental disorder with core symptoms like interpersonal instability, emotion dysregulation, self-harm, and impulsive decision-making. Previous neuropsychological studies have found impairment in the decision-making of patients with BPD related to impulsivity. In our study, we focus on a better, more nuanced understanding of impulsive decision-making in BPD with the help of Rogers' decision-making test that simulates a gambling situation.

Role of Altered Metabolism of Triglyceride-Rich Lipoprotein Particles in the Development of Vascular Dysfunction in Systemic Lupus Erythematosus.

Background: Impaired lipid metabolism contributes to accelerated inflammatory responses in addition to promoting the formation of atherosclerosis in systemic lupus erythematosus (SLE). We aimed to evaluate the lipid profile, inflammatory markers, and vascular diagnostic tests in active SLE patients to clarify the association between dyslipidemia and early vascular damage.

Patients And Methods: 51 clinically active SLE patients and 41 age- and gender-matched control subjects were enrolled in the study.

Monitoring and recovery of hyperglycaemia-induced endothelial dysfunction with rheopheresis in diabetic lower extremity ulceration with hyperviscosity.

Aims: Rheopheresis is an extracorporeal haematotherapy that improves haemorheological status by filtering proteins that enhance blood viscosity. It also has anti-inflammatory effects by removing inflammatory cytokines. Our study aims to examine the effects of rheopheresis on the endothelial status in diabetic lower extremity ulceration.

The Predictive Role of Thyroid Hormone Levels for Early Diabetic Retinal Changes in Experimental Rat and Human Diabetes.

Purpose: In diabetic subjects, early visual functional alterations such as color vision deficiencies (CVDs) are known to precede clinically apparent diabetic retinopathy. Prominent photoreceptor outer segment degeneration and an increase in the number of retinal dual cones (co-expressing S- and M-opsins simultaneously) have been described in diabetic rat models, suggesting a connection with the development of CVDs. As cone opsin expression is controlled by thyroid hormones, we investigated the diabetic retina in association with thyroid hormone alterations.

Anti-β-glycoprotein I autoantibodies influence thrombin generation parameters via various mechanisms.

Introduction: Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterised by recurrent thrombotic events, pregnancy loss and thrombocytopenia and the presence of antiphospholipid antibodies (APL). The exact pathomechanism of APS is still unknown, thus we investigated the effect of anti-β-glycoprotein I (anti-βGPI) on thrombin generation in different plasma samples.

Methods: For the separation of anti-βGPI IgG, overall 12 APS patients were selected.

Distinct and overlapping effects of β-glycoprotein I conformational variants in ligand interactions and functional assays.

One of the most abundant coagulation proteins is β-glycoprotein I (βGPI) that is present in humans at a concentration of around 200 mg/L. Its physiological role is only partially understood, but it adopts several different structural forms the majority of which are the open and closed forms. We isolated native (circular) βGPI and converted it into an open conformation.

Correction to: A prospective, longitudinal monocentric study on laser Doppler imaging of microcirculation: comparison with macrovascular pathophysiology and effect of adalimumab treatment in early rheumatoid arthritis.

A prospective, longitudinal monocentric study on laser Doppler imaging of microcirculation: comparison with macrovascular pathophysiology and effect of adalimumab treatment in early rheumatoid arthritis.

Increased cardiovascular (CV) morbidity and mortality have been found in rheumatoid arthritis (RA). Tumour necrosis factor α (TNF-α) inhibitors may improve vascular function. In the first part of this study, we determined microcirculation during postoocclusive reactive hyperemia (PORH) representing endothelial function.

[-induced immunglobulin E-dependent allergic anaphylaxis in Crohn's disease. ].

Immunglobulin E (IgE)-based, irregularly recurring, severe anaphylactic reactions occurred in a 50-year-old European white male patient suffering also from Crohn's disease. On the base of immunologic laboratory tests concerning the mechanism of the phenomenon, the idea arose whether molecules derived for certain microbial derivatives could enter the blood circulation the damaged bowel walls in the patient with Crohn's disease and they might act as allergens. The microbial analysis diagnosed atypical in the stool.

[National survey of the therapeutic apheresis in Hungary, 2013-2017].

Therapeutic apheresis is a treatment option for several subspecialities. It is a relatively expensive intervention, which can only be done by dedicated centers based on specific indications. The Therapeutic Apheresis Committee and the National Health Insurance Fund of Hungary jointly control the number of interventions to be made, the introduction of new diagnoses and the application of new apheresis procedures in Hungary.

Hypertension-induced subclinical vascular and cognitive changes are reversible-An observational cohort study.

Beside the well-known complications of poorly controlled, long-standing hypertension, milder abnormalities induced by early-stage hypertension have also been described. In our study, the authors examined the reversibility of changes induced by early-stage hypertension. The authors performed laboratory testing, ambulatory blood pressure monitoring, carotid intima-media thickness (IMT) measurement, evaluation of stiffness parameters, assessment of various cardiac and cerebral hemodynamic parameters during head-up tilt table (HUTT) testing, and neuropsychological examinations in 49 recently diagnosed hypertensive patients.

Microthrombotic renal involvement in an SLE patient with concomitant catastrophic antiphospholipid syndrome: the beneficial effect of rituximab treatment.

Antiphospholipid syndrome is characterized by multiple arterial and/or venous thrombotic events, recurrent fetal losses in the presence of antiphospholipid antibodies (aPL). Catastrophic antiphospholipid syndrome is a life-threatening, rare subset of antiphospholipid syndrome when the thrombotic events affect at least three organs, and clinical manifestations develop simultaneously or within a week. Diagnostically, small vessel occlusions can be detected by histopathology in the presence of aPL.

[Immunoadsorption in a patient with dilated cardiomyopathy. The first case in Hungary].

Dilated cardiomyopathy is the main cause of heart transplantation. The etiology is unknown in almost half of the cases. Many cardiac specific antibodies have been identified till now which can cause decreased cardiac function, ventricular tachycardia or sudden heart death.

Posterior-Anterior Brain Maturation Reflected in Perceptual, Motor and Cognitive Performance.

Based on several postmortem morphometric and imaging studies it has been postulated that brain maturation roughly follows a caudal to rostral direction. In this study, we linked this maturational pattern to psychological function employing a series of well-established behavioral tasks. We addressed three distinct functions and brain regions with a perceptual (contour integration, CI), motor (finger tapping, FT), and executive control (Navon global-local) task.

Rheopheresis in vascular diseases.

Rheopheresis is an extracorporal selective double-filtration procedure. In the first part of the treatment the blood is passes through the plasma filter, which separates blood cells from the plasma. Then the plasma flow to a second filter called MONET (Membranefiltration Optimised Novel Extracorporal Treatment).

[Favourable effects of kidney transplantation on vascular condition of patients: Potential prognostic significance of non-invasive measurement of arterial stiffness].

Introduction: Development of atherosclerosis is accelerated in kidney transplant patients. Impaired metabolic pathways have complex effect on the arterial wall which can be measured by non-invasive techniques. Only few data are available on the change of stiffness parameters in the postoperative course.

Elevated LDL-C combined with hypertension worsens subclinical vascular impairment and cognitive function.

Hypertension and dyslipidemia belong to the most prevalent modifiable risk factors for cerebrovascular and cardiovascular diseases. Hereby, we aimed to examine the combined effects of newly diagnosed hypertension and hyperlipidemia on the characteristics of the arterial wall and on cognitive function. We examined 72 hypertensive and 85 apparently healthy individuals.

Three-year longitudinal clinical trial of arterial function assessed by a oscillometric non-invasive method in comparison with carotid sclerosis and transferrin kidney-transplanted patients.

Chronic kidney disease remains one of the main risk factors of cardiovascular disease. However, patients with kidney transplantation have better life expectancy and better quality of life compared with patients on dialysis. In patients with a well-functioning graft, the main cause of death is cardiovascular in origin.

Rheumatoid arthritis and metabolic syndrome.

Rheumatoid arthritis (RA), especially active disease, is associated with considerable changes in body composition, lipids, adipokines and insulin sensitivity. Metabolic changes, such as increased total cholesterol, LDL cholesterol and triglyceride levels, occur even in preclinical RA. Active RA is associated with decreased lipid levels, BMI, fat and muscle mass, as well as altered lipid profiles.
