Introduction and objectives
The association between HDL cholesterol (HDL-C) levels and death from cardiovascular disease follows a U-shaped pattern, increasing at the extremes. The objective of the study was to characterize a sample of subjects with extreme hyperalphalipoproteinemia (HAE).
Material and methods
53 cases with HAE were recruited, 24 women (HDL-C > 135 mg/ dL) and 29 men (HDL-C > 116 mg/ dL). A detailed medical history was taken and questionnaires on adherence to the Mediterranean diet and physical activity were collected. Carotid ultrasounds were performed to detect the presence of suclinical atherosclerosis.
Results
The most prevalent cardiovascular risk factor (CVRF) was dyslipidemia (64%) with no significant differences between men and women, unlike hypertension (21% in women, versus 55% in men, p = 0.01) and others CVRF, for example, diabetes. 7% of the series had previous cardiovascular disease, women had higher LDL cholesterol (p = 0.002) and HDL-C than men (without significant differences). Plaque was detected in 53% of cases, being more prevalent in men. Patients with plaque were older, drank more alcohol and smoked more (p < 0.05).
Conclusions
Men had a higher prevalence of CVRF than women, except for dyslipidemia. Subclinical atherosclerosis occurred in more than half of the series. Age, alcohol consumption and smoking were independently associated with the presence of plaque, however, our data do not show a significant influence of HDL-C levels.

To understand the prevalence of subclinical atherosclerosis (SCA) in psoriatic arthritis (PsA) patients; to explore the correlation between PsA combined with SCA and traditional cardiovascular risk factors and disease activity; to compare the role of Framingham Risk Score (FRS) and atherosclerotic cardiovascular disease (ASCVD) scores.
Methods
We included 50 PsA patients who met the CASPAR classification criteria, 50 diabetes patients and 50 healthy people. Clinical data were collected from all patients, minimal disease activity (MDA), disease activity index for psoriatic arthritis (DAPSA), ASCVD, FRS were assessed in patients with PsA, and carotid artery intima–media thickness was measured.
Results
The prevalence of SCA in PsA patients was significantly higher than that in healthy controls (44% vs 24%, P < 0.05). Smoking, drinking, ASCVD, FRS were the risk factors of PsA with SCA (P < 0.05). Psoriasis (PsO) duration, PtGA, VAS and DAPSA were the risk factors for PsA with SCA (P < 0.05). FRS and ASCVD scores underestimated SCA risk in PsA patients.
Conclusion
Compared with healthy controls, patients with PsA have higher prevalence of SCA. High DAPSA is a risk factor for PsA with SCA. Carotid ultrasound can monitor SCA in patients with PsA, improve stratification of cardiovascular risk.

Aim
Epidemiological evidence suggests adherence to vegetable-rich diets is associated to atheroprotective effects and bioactive components are most likely to play a relevant role. The notion of inter-kingdom regulation has opened a new research paradigm and perhaps microRNAs (miRNAs) from edible vegetables could influence consumer gene expression and lead to biological effects. We aimed to investigate the potential impact of broccoli-derived miRNAs on cellular cholesterol efflux in vitro.
Methods
Four miRNAs (miR159a, miR159b, miR166a and miR403) from Brassica oleracea var. italica (broccoli), a widely consumed cruciferous vegetable, were selected for further investigation, based on their high abundancy in this vegetable and their presence in other plants. Selected miRNAs were synthesized with a 3′-terminal 2′-O-methylation and their cellular toxicity, in vitro gastrointestinal resistance and cellular uptake were evaluated. Potential target genes within the mammalian transcriptome were assessed in silico following pathway analysis. In vitro cholesterol efflux was assessed in human THP-1-derived macrophages.
Results
miRNAs survival to in vitro GI digestion was around 1%, although some variation was seen between the four candidates. Cellular uptake by mammalian cells was confirmed, and an increase in cholesterol efflux was observed. Pathway analysis suggested these miRNAs are involved in biological processes related to phosphorylation, phosphatidylinositol and Wnt signaling, and to the insulin/IGF pathway.
Conclusions
Health-promoting properties attributed to cruciferous vegetables, might be mediated (at least in part) through miRNA-related mechanisms.

Pathological vascular remodeling of the vessel wall refers to the structural and functional changes of the vessel wall that occur in response to injury that eventually leads to cardiovascular disease. The vessel wall is composed of two main types of cells, endothelial cells and vascular smooth muscle cells, whose communication is crucial in both the development of the vasculature and the homeostasis of mature vessels. Changes in the dialogue between endothelial cells and vascular smooth muscle cells are associated with various pathological states that triggers remodeling of the vascular wall. For many years, considerable efforts have been made to develop effective diagnoses and treatments for these pathologies by studying their mechanisms in both in vitro and in vivo models. Compared to animal models, in vitro models can provide great opportunities to obtain data in a more homogeneous, economical and massive way, providing an overview of the signaling pathways responsible for these pathologies. The implementation of three-dimensional in vitro co-culture models for the study of other pathologies has been postulated as a potentially applicable methodology, which determines the importance of its application in studies of cardiovascular diseases. In this article we present a method for culturing human endothelial cells and vascular smooth muscle cells, grown under non-adherent conditions, that generate three-dimensional spheroidal structures with greater physiological equivalence to in vivo conditions. This in vitro modeling could be used as a study tool to identify cellular and molecular mechanisms involved in the pathological processes underlying vascular remodeling.

Introduction
Despite the key role of the endothelium in atherosclerosis, there are no direct techniques for its analysis. The study of extracellular vesicles of endothelial origin (EEVs), might lead to the identification of molecular signatures and early biomarkers of atherosclerosis. The aim of this work was to set up the methods for EEVs separation and transcriptomic analysis.
Methods
We adapted an antibody-magnetic-bead based immunocapture protocol for plasma EEVs separation from control (G1), subclinical atherosclerosis (G2) and peripheral artery disease subjects (PAD) (G3), and modified an ultra-low input RNASeq method (n = 5/group). By bioinformatics analysis we compared the transcriptome of plasma EEVs with that of human aortic endothelial cells (TeloHAECs), and then, searched for differentially expressed genes (DEG) among EEVs of G1, G2 and G3. From those DEG, UCP2 was selected for further validation in plasma EVs (qPCR), and in vitro, in stimulated TeloHAECs (IL-1β, TNFα, oxLDL and hypoxia).
Results
The RNASeq analysis of plasma EEVs rendered 1667 genes enriched in transcripts expressed by TeloHAECs (NES: 1.93, p adjust = 1.4e−73). One hundred seventy DEGs were identified between G2 vs G1, and 180 between G3 vs G1, of which 17 were similarly expressed in G2 and G3 vs control, including UCP2. IL-1β and TNFα (10 ng/mL, p < 0.05), hypoxia (1% O2, p = 0.05) and oxLDL (100 μg/mL, p = 0.055) reduced UCP2 expression in TeloHAECs.
Conclusions
We set up a protocol for EEVs separation and sequencing that might be useful for the identification of early markers of endothelial dysfunction in atherosclerosis.
