High-resolution MRI assessed carotid atherosclerotic plaque characteristics comparing men and women with elevated ApoB levels

AbstractPrevious studies demonstrated that men were more likely to have plaque rupture and are at greater risk for myocardial infarction and stroke than women. We evaluated differences in carotid plaque characteristics by MRI between men and women with mild-moderate atherosclerosis and elevated ApoB levels. One hundred eighty-two subjects (104 men and 78 women) with CAD or carotid stenosis ( ≥ 15% by ultrasound), ApoB ≥ 120 mg/dL and carotid MRI scan were included. Percent wall volume (%WV) was calculated as (wall volume/total vessel volume) × 100%. Three major plaque compositions, fibrous tissue (FT), calcification (CA) and lipid rich necrotic core (LRNC), were identifi ed and quantified using published MRI criteria. Adventitial and plaque neovascularization as fractional plasma volume (Vp) and permeability as transfer constant (Ktrans) were analyzed using kinetic modeling. These characteristics were compared between men and women. Men, compared to women, were younger (54  ± 8 vs. 58 ± 8 years,p  =  0.01), had higher rate of previous MI (46 vs. 26%,p  =  0.005) but lower proportions of metabolic syndrome (37 vs. 59%,p  =  0.003). After adjusting for between-gender differences, men were significantly more likely to have LRNC (OR 2.22, 95% CI 1.04–4.89,p  =  0.04) and showed significantly larger %LRNC than women (diff&...

Authors: Oszukowska M, Kozłowska M, Kaszuba A Abstract Introduction: Psoriasis is considered as a risk factor for atherosclerosis and contributes to myocardial infarction, ischemic heart disease and brain stroke. Aim: To estimate the atherogenic potential of psoriasis by analysing antioxidative and prooxidative factors (paraoxonase-1, α-tocopherol, uric acid, homocysteine), compare levels of these parameters between groups of psoriatic patients and healthy individuals as well as to analyse the impact of psoriasis severity and duration on the factors under the study and to define correlation between the m...

CONCLUSION: On the basis of a broadly based research and participatory development process, a set of indicators has been developed that enables comprehensive evaluation of the regional quality of care of cross-indication, integrated care models focusing on common diseases. In order to be able to increasingly evaluate aspects of care coordination and patient orientation, health promotion as well as nursing, palliative and emergency care in the future, it would be helpful if routine data were collected or made accessible in these areas as well.

In this study, we investigated the link between AF and senescence markers through the assessment of protein expression in the tissue lysates of human appendages from patients in AF, including paroxysmal (PAF) or permanent AF (PmAF), and in sinus rhythm (SR). The major findings of the study indicated that the progression of AF is strongly related to the human atrial senescence burden as determined by p53 and p16 expression. The stepwise increase of senescence (p53, p16), prothrombotic (TF), and proremodeling (MMP-9) markers observed in the right atrial appendages of patients in SR, PAF, and PmAF points toward multiple inter...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epige...

Abstract Objective: The underlying mechanisms by which cystatin C affects cardiovascular disease (CVD) are not very clear. Metabolic syndrome (MetS) is a cluster of risk factors that increase the risk of CVD. Here, we aimed to investigate the association of cystatin C with metabolic syndrome and cardiovascular outcomes in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) with preserved renal function. Methods: In total, 422 NSTE-ACS patients with preserved renal function were enrolled to examine the association of cystatin C with MetS. MetS was defined based on the NCEP-ATP-III guidelines. Major adv...

AbstractIntroductionThe main objective of this research was to evaluate the association of insulin resistance (IR) with micro- and macrovascular complications, sex hormones, and other clinical data.MethodsCross-sectional study of patients older than 18  years old with type 1 diabetes mellitus (T1DM) was performed. Participants filled in questionnaires about T1D, disease duration, smoking, glycemic control, chronic diabetes complications, and hypertension status. Data about chronic diabetic complications (neuropathy, retinopathy, and nephropathy) were collected from medical records. History of major cardiovascular even...

Abstract The modern way of life contributes to the higher frequency of a complex state medically called metabolic syndrome (MetS), which is an inevitable consequence of several most common diseases of modern civilization. Patients with MetS have three times higher risk of experiencing a heart attack or a stroke and twice higher possibility to die from them. Serbia holds the infamous third place in Europe in mortality from heart disease, just behind Russia and Ukraine. The study explores the correlation of every combination of genotypes of apoE (apolipoprotein E) and LRP1 (low density receptor- related protein 1) g...
