Abstract Ulcerative colitis (UC) is a chronic immune-mediated disorder, whose etiology not fully understood and for which no effective treatment available. Recently, research has focused on the dysbiosis of gut microbiome in UC. However, results so far remain inconsistent insufficient to understand microbial component UC pathogenesis. In this study, we determine specific changes profile Polish patients compared healthy subjects first time. Using 16S rRNA gene-based analysis have described...

Background: Several perioperative inflammatory markers are postulated to be significant factors for long-term survival after off-pump coronary artery bypass surgery (OPCAB). Hematological parameters, whether single or combined as indices, provide higher predictive values. Methods: The study group comprised 538 consecutive patients (125 (23%) females and 413 (77%) males) with a mean age of 65 ± 9 years, who underwent OPCAB follow-up time 4.7 1.7 years. This single-center retrospective...

Cardiovascular diseases, apart from commonly known risk factors, are related to inflammation. There several simple novel markers proposed present the relation between inflammatory reactions activation and atherosclerotic changes. They easily available whole blood count include neutrophil lymphocyte ratio (NLR), monocyte (MLR), platelets (PLR). The RDW results were excluded analysis.The study based on retrospective single-centre analysis of 682 consecutive patients (131 (19%) females 551...

Electroconvulsive therapy (ECT) is the most effective treatment for drug-resistant depression (DRD). We estimated short- and long-term effects of ECT on cognitive functions in patients with unipolar bipolar DRD.We investigated 63 (18 male, 45 female), aged 34-75 years. Cognitive assessments were performed before, immediately after 6-12 sessions, 3 months thereafter, using Benton Visual Retention, Trail Making (TMT), Rey-Osterrieth Complex Figure (ROCF) tests, Digit Span Wechsler Adult...

Platelets participate in the development and progression of atherosclerosis. During this process they interact with endothelial cells leukocytes. Therefore, we investigated associations between carotid atherosclerosis platelet reactivity markers. The surface expression P-selectin (CD62P) activated GPIIb/IIIa receptor (corresponding to increased binding PAC-1), as well fraction platelet-derived microparticles (PMPs) prior after stimulation TRAP or ADP, were determined using flow cytometry 94...

Background: Off-pump coronary artery bypass grafting (OPCAB) comprises 15–30% of all surgeries. The currently available perioperative scores such as Euroscore and STS score do not specifically predict long-term mortality after off-pump procedures. neutrophil-to-lymphocyte ratio (NLR) is one the new, easily accessible markers inflammation with proven predictive value in cardiovascular diseases. We aimed to develop first risk for OPCAB determine if NLR predicts patients. Methods: In total, 440...

Background: Currently, atherosclerotic cardiovascular disease is the major cause of mortality world-wide. Inflammatory processes are postulated to be a driving force for coronary plaque initiation and progression can evaluated by simple inflammatory markers from whole blood count analysis.
