Seasonal and Treatment-Related Variation in 25-Hydroxy Vitamin D Concentration in Patients with Rheumatoid Arthritis.

: 25-hydroxy vitamin D (25-OH-D) is a fat-soluble compound that plays many essential functions, including bone formation, neuromuscular functions, and prevention of osteoporosis and inflammation. Recent data indicate that its metabolites are associated with rheumatoid arthritis (RA) progression and neuropathic pain in RA patients. We aimed to assess the effect of RA pharmacotherapy and seasonal variation on serum levels of 25-OH-D in RA patients who received treatment with methotrexate (MTX) or leflunomide (LEF) for at least one year.

Circulating miRNA-451a and miRNA-328-3p as Potential Markers of Coronary Artery Aneurysmal Disease.

MicroRNAs (miRNAs) are currently investigated as crucial regulatory factors which may serve as a potential therapeutic target. Reports on the role of miRNA in patients with coronary artery aneurysmal disease (CAAD) are limited. The present analysis aims to confirm the differences in the expression of previously preselected miRNAs in larger study groups and evaluate their usefulness as potential markers of CAAD.

Neopterin as a predictive biomarker of postoperative atrial fibrillation following coronary artery bypass grafting.

Background: The pathophysiology of postoperative atrial fibrillation (POAF) is multifactorial. Inflammation and increased oxidative stress play a significant role in POAF development. Neopterin, a biomarker of cellular immune response that enhances oxidative stress and increases the cytotoxic potential of activated macrophages and dendritic cells, was recently found as an independent predictive biomarker of non-operative atrial fibrillation.

Circulating microRNAs in patients with aneurysmal dilatation of coronary arteries.

To understand the mechanism underlying coronary artery abnormal dilatation (CAAD), the present study identified and compared the expression of circulating microRNAs (miRNAs) in three groups of patients. Group 1 included 20 patients with CAAD, Group 2 included 20 patients with angiographically confirmed coronary artery disease (CAD), and Group 3 included 20 patients with normal coronary arteries (control). miRNAs were isolated from plasma samples and were profiled using PCR arrays and miRCURY LNA Serum/Plasma Focus PCR Panels.

Involvement of Angiogenesis in the Pathogenesis of Coronary Aneurysms.

The present study aimed to evaluate the plasma concentration of pro and antiangiogenic factors and their role in the pathogenesis of coronary artery abnormal dilation (CAAD). We measured the plasma concentration of matrix metalloproteinase-8 (MMP-8), transforming growth factor beta 1 (TGF-β1), Angiopoietin-2, vascular endothelial growth factor (VEGF), and fibroblast growth factor (FGF) using a sandwich ELISA technique in the plasma of patients with coronary artery abnormal dilation (CAAD, Group 1), coronary artery disease (CAD, Group 2), and normal coronary arteries (NCA, Group 3). Patients suffering from CAAD showed significantly higher plasma concentrations of VEGF ( = 0.

Endocan expression correlated with total volume of coronary artery dilation in patients with coronary artery ectasia.

Introduction: Inflammation and angiogenesis disturbances are considered as factors contributing to the development of coronary artery ectasias (CAE). Endocan (endothelial cell-specific molecule-1 - ESM-1) regulates both inflammatory and angiogenetic processes. However, there are no data about the correlation between endocan level and the severity of CAE measured with total volume of coronary artery dilation.

Prognostic Value of Oxidative Stress Markers in Patients with Pulmonary Arterial or Chronic Thromboembolic Pulmonary Hypertension.

Oxidative stress is regarded to play a crucial role in the pathophysiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). This study evaluated the prognostic value of serum oxidative stress markers (malondialdehyde (MDA), total antioxidant capacity (TAC), catalase activity (CAT), and superoxide activity (SOD)) in patients with PAH and CTEPH ( = 45). During 13 months of follow-up (median 9 months), clinical deterioration occurred in 14 patients (including 2 deaths).

Photosensitivity reactions in the elderly population: questionnaire-based survey and literature review.

Purpose: Older people are at risk of developing adverse drug reactions, including photosensitivity reactions. Therefore, the aim of the study was to assess the use of potentially photosensitizing medications and photoprotection in the elderly population.

Patients And Methods: Three hundred and fifty-six respondents (223 [63%] women and 133 [37%] men) aged ≥65 years filled in the original questionnaire concerning photosensitivity reactions to drugs.

Is it possible to prevent chemotherapy-induced heart failure with cardiovascular drugs - the review of the current clinical evidence.

Cardiovascular diseases and cancer are the most common death causes in the USA and Europe. Moreover, many patients suffer from both of these conditions - a situation which may result from cardiotoxicity of anticancer treatment. In order to reduce the severity of this adverse effect, various methods have been proposed, including the usage of new drug forms and less toxic analogs, omitting the combinations of potentially cardiotoxic drugs and introducing potential cardioprotective agents to the therapy.

Neopterin as a Biomarker in Patients with Pulmonary Arterial Hypertension and Chronic Thromboembolic Pulmonary Hypertension.

Background: Upregulation of the immune system is regarded to play an important role in the etiopathobiology of pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). To the best of our knowledge, neopterin (NP) has never been investigated in patients with PAH and CTEPH.

Objectives: The aim of the study was to evaluate the concentration of NP in blood in order to examine its impact on outcome and relationship with disease severity in that population.

Coenzyme Q10 - A new player in the treatment of heart failure?

Coenzyme Q10 is the only endogenously synthesized lipid with a redox function which exhibits broad tissue and intracellular distribution in mammals. Beneficial effects of Coenzyme Q10 supplementation were observed in several age-related diseases including heart failure. CoQ10 (coenzyme Q10) level is significantly decreased in patients with this disease, which correlates with severity of clinical symptoms.

[Analysis of the problem of addiction in the elderly].

Current approach for detection of sub-clinical left ventricular dysfunction associated with chemotherapy.

The article describes the current knowledge concerning approaches for detection of sub-clinical left ventricular dysfunction associated with chemotherapy. The authors focused on the problem of defining cardiotoxicity as well as diagnostic methods, which may be useful in predicting the occurrence of such complications. Currently, cardiac biomarkers measurement (troponin, NT-proBNP), tissue Doppler-based strain imaging and peak systolic longitudinal strain rate are most useful for detection of early myocardial changes during therapy, whereas speckle tracking echocardiography (STE) and peak systolic global longitudinal strain (GLS) appear to be the best measure.

[Safety of nicotine addiction treatment].

Not all smoking addicts can succeed in quitting smoking with willpower only. These people may use nicotine replacement therapy (patches, gums, lozenges, sublingual tablets, inhalers), medicines (bupropion, varenicline and cytisine) and psychological aid. Each drug, besides its therapeutic effect, creates the risk of adverse reactions which number and severity is not always accepted by the patient.
