Predicting Subclinical Atherosclerosis in Low-Risk Individuals Ideal Cardiovascular Health Score and Fuster-BEWAT Score
BACKGROUND The ideal cardiovascular health score (ICHS) is recommended
for use in primary prevention. Simpler tools not requiring laboratory
tests, such as the Fuster-BEWAT (blood pressure [B], exercise [E],
weight [W], alimentation [A], and tobacco [T]) score (FBS), are
also available.
OBJECTIVES The purpose of this study was to compare the effectiveness of
ICHS and FBS in predicting the presence and extent of subclinical
atherosclerosis.
METHODS A total of 3,983 participants 40 to 54 years of age were
enrolled in the PESA (Progression of Early Subclinical Atherosclerosis)
cohort. Subclinical atherosclerosis was measured in right and left
carotids, abdominal aorta, right and left iliofemoral arteries, and
coronary arteries. Subjects were classified as having poor,
intermediate, or ideal cardiovascular health based on the number of
favorable ICHS or FBS.
RESULTS With poor ICHS and FBS as references, individuals with ideal
ICHS and FBS showed lower adjusted odds of having atherosclerotic
plaques (ICHS odds ratio [OR]: 0.41; 95\% confidence interval [CI]:
0.31 to 0.55 vs. FBS OR: 0.49; 95\% CI: 0.36 to 0.66), coronary artery
calcium (CACS) >= 1 (CACS OR: 0.41; 95\% CI: 0.28 to 0.60 vs. CACS OR:
0.53; 95\% CI: 0.38 to 0.74), higher number of affected territories (OR:
0.32; 95\% CI: 0.26 to 0.41 vs. OR: 0.39; 95\% CI: 0.31 to 0.50), and
higher CACS level (OR: 0.40; 95\% CI: 0.28 to 0.58 vs. OR: 0.52; 95\%
CI: 0.38 to 0.72). Similar levels of significantly discriminating
accuracy were found for ICHS and FBS with respect to the presence of
plaques (C-statistic: 0.694; 95\% CI: 0.678 to 0.711 vs. 0.692; 95\% CI:
0.676 to 0.709, respectively) and for CACS >= 1 (C-statistic: 0.782;
95\% CI: 0.765 to 0.800 vs. 0.780; 95\% CI: 0.762 to 0.798,
respectively).
CONCLUSIONS Both scores predict the presence and extent of subclinical
atherosclerosis with similar accuracy, highlighting the value of the FBS
as a simpler and more affordable score for evaluating the risk of
subclinical disease. (C) 2017 The Authors. Published by Elsevier on

Midterm outcome of patients with asymptomatic restenosis after coronary balloon angioplasty
AbstractAlthough many patients with restenosis after balloon coronary angioplasty have recurrence of angina, others remain asymptomatic. To assess the clinical implications of asymptomatic coronary restenosis, we analyzed clinical and angiographie characteristics of 277 consecutive patients with restenosis, 133 (48%) of whom were asymptomatic (group I) and 144 (52%) symptomatic (group II). Restenosis was documented 6 to 9 months after the index procedure, or earlier if angina recurred, and was defined as a >50% lumen narrowing (visual estimation). Group I (asymptomatic group) included fewer female (9% vs. 18%, p < 0.05) and hypertensive patients (38% vs. 56%, p < 0.005) and more patients with a previous myocardial infarction (48% vs. 28%, p < 0.05) and single-vessel disease (67% vs. 55%, p < 0.05).Before angioplasty, symptoms had lasted for a shorter period (10 ± 25 vs. 23 ± 42 months, p < 0.001), ischemia after a recent infarction was a more frequent indication (21% vs. 10%, p < 0.05) and total revascularization more frequently obtained (74% vs. 63%, p < 0.05) in group I than in group II patients. Only a normal blood pressure, previous myocardial infarction, singlevessel disease and a shorter duration of symptoms were independent correlates of asymptomatic restenosis. No differences were found in stenosis severity before angioplasty (90% in both groups) or after angioplasty (22% ± 12% vs. 24% ± 16%).By the time of follow-up angiography, group I patients had exercised more (9.8 ± 2.7 vs. 7.7 ± 3 metabolic exercise equivalents (METs), p < 0.05) and had achieved a faster heart rate (140 ± 21 vs. 127 ± 23 beats/min, p < 0.025), and more of them had a negative test result (33% vs. 9%, p < 0.05). Stenosis was less severe in group I patients (79 ± 15% vs. 86 ± 11%, p < 0.05), and 32% of them versus 8% of group II had <75% stenosis. After 17 ± 13 months, 15 asymptomatic patients had recurrence of angina; recurrence was considered related to restenosis in 6 (21%) of 29 patients with exercise-induced ST segment changes, in 4 (9.5%) of 42 without ST changes and in none of the 15 with ST changes and “elective” angioplasty. No group I patient died or was operated on, and only six underwent another angioplasty procedure indicated for angina. By contrast, 6 patients (4%) in group II died, 11 (8%) required surgery and 81 (56%) underwent repeat angioplasty.It is concluded that asymptomatic coronary restenosis is a frequent phenomenon with a good prognosis mainly in patients with a negative exercise test result. Prospective, randomized studies are required to determine the potential role of repeat angioplasty in asymptomatic patients with documented restenosis and evidence of exercise-induced ST segment changes
Does Socioeconomic Status Influence the Risk of Subclinical Atherosclerosis?: A Mediation Model
BACKGROUND: Socioeconomic status (SES)-education, income level, and occupation-is associated with cardiovascular risk. OBJECTIVES: This study aimed to investigate the association between SES and subclinical atherosclerosis and the potential mechanisms involved. METHODS: SES, lifestyle habits (smoking, dietary patterns, physical activity, and hours of sleep), traditional risk factors, and subclinical atherosclerosis extent were prospectively assessed in 4,025 individuals aged 40 to 54 years without known cardiovascular disease enrolled in the PESA (Progression of Early Subclinical Atherosclerosis) study. After factors associated with atherosclerosis were identified, a multiple mediation model was created to quantify the effect of SES on subclinical atherosclerosis as explained by lifestyle behaviors. RESULTS: Although education level was significantly associated with the presence of atherosclerosis, no differences were found according to income level in this population. Participants with lower education presented with a higher risk of generalized atherosclerosis than those with higher education (odds ratio: 1.46; 95% confidence interval: 1.15 to 1.85; p = 0.002). Lifestyle behaviors associated with both education level and atherosclerosis extent were: smoking status, number of cigarettes/day, and dietary pattern, which explained 70.5% of the effect of SES on atherosclerosis. Of these, tobacco habit (smoking status 35% and number of cigarettes/day 32%) accounted for most of the explained differences between groups, whereas dietary pattern did not remain a significant mediator in the multiple mediation model. CONCLUSIONS: Despite the relative economic homogeneity of the cohort, lower education level is associated with increased subclinical atherosclerosis, mainly mediated by the higher and more frequent tobacco consumption. Smoking cessation programs are still needed, particularly in populations with lower education level.The PESA study is cofunded equally by the Fundación Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC), Madrid, Spain; and Banco Santander, Madrid, Spain.

Oxidized LDL Is Associated With Metabolic Syndrome Traits Independently of Central Obesity and Insulin Resistance
This study assesses whether oxidative stress, using oxidized LDL (ox-LDL) as a proxy, is associated with metabolic syndrome (MS), whether ox-LDL mediates the association between central obesity and MS, and whether insulin resistance mediates the association between ox-LDL and MS. We examined baseline data from 3,987 subjects without diabetes in the Progression of Early Subclinical Atherosclerosis (PESA) Study. For the second, third, and fourth ox-LDL quartiles versus the first, the odds ratios (95% CI) for MS were 0.84 (0.52, 1.36), 1.47 (0.95, 2.32), and 2.57 (1.66, 4.04) (P < 0.001 for trend) once adjusted for age, sex, smoking, LDL-cholesterol, BMI, waist circumference, and HOMA-insulin resistance (HOMA-IR). Results showing the same trend were found for all MS components except glucose concentration. Ox-LDL mediated 13.9% of the association of waist circumference with triglycerides and only 1-3% of the association with HDL-cholesterol, blood pressure, and insulin concentration. HOMA-IR did not mediate the association between ox-LDL and MS components. This study found higher ox-LDL concentrations were associated with MS and its components independently of central obesity and insulin resistance. Ox-LDL may reflect core mechanisms through which MS components develop and progress in parallel with insulin resistance and could be a clinically relevant predictor of MS development.Y.H.-R. received support from Republic of Peru and the Inter-American Development Bank through FINCyT Science and Technology Program Scholarships No. 088-FINCyT-BDE-2014 under agreement 1663/OC-PE.

Recent GRBs observed with the 1.23m CAHA telescope and the status of its upgrade
We report on optical observations of Gamma-Ray Bursts (GRBs) followed up by
our collaboration with the 1.23m telescope located at the Calar Alto
observatory. The 1.23m telescope is an old facility, currently undergoing
upgrades to enable fully autonomous response to GRB alerts. We discuss the
current status of the control system upgrade of the 1.23m telescope. The
upgrade is being done by the ARAE our group, based on members of IAA (Instituto
de Astrofiisica de Andalucia). Currently the ARAE group is responsible to
develop the BOOTES network of robotic telescopes based on the Remote Telescope
System, 2nd Version (RTS2), which controls the available instruments and
interacts with the EPICS database of Calar Alto. Currently the telescope can
run fully autonomously or under observer supervision using RTS2. The fast
reaction response mode for GRB reaction (typically with response times below 3
minutes from the GRB onset) still needs some development and testing. The
telescope is usually operated in legacy interactive mode, with periods of
supervised autonomous runs under RTS2. We show the preliminary results of
several GRBs followed up with observer intervention during the testing phase of
the 1.23m control software upgrade.Comment: 15 pages, 7 figures. Accepted for publication in the Special issue

Glycated Hemoglobin, Fasting Insulin and the Metabolic Syndrome in Males. Cross-Sectional Analyses of the Aragon Workers' Health Study Baseline
Background and Aims
Glycated hemoglobin (HbA1c) is currently used to diagnose diabetes
mellitus, while insulin has been relegated to research. Both, however,
may help understanding the metabolic syndrome and profiling patients. We
examined the association of HbA1c and fasting insulin with clustering of
metabolic syndrome criteria and insulin resistance as two essential
characteristics of the metabolic syndrome.
Methods
We used baseline data from 3200 non-diabetic male participants in the
Aragon Workers' Health Study. We conducted analysis to estimate
age-adjusted odds ratios (ORs) across tertiles of HbA1c and insulin.
Fasting glucose and Homeostatic model assessment - Insulin Resistance
were used as reference. Here we report the uppermost-to-lowest tertile
ORs (95\% CI).
Results
Mean age (SD) was 48.5 (8.8) years and 23\% of participants had
metabolic syndrome. The ORs for metabolic syndrome criteria tended to be
higher across HbA1c than across glucose, except for high blood pressure.
Insulin was associated with the criteria more strongly than HbA1c and
similarly to Homeostatic model assessment - Insulin Resistance
(HOMA-IR). For metabolic syndrome, the OR of HbA1c was 2.68, of insulin,
11.36, of glucose, 7.03, and of HOMA-IR, 14.40. For the clustering of 2
or more non-glycemic criteria, the OR of HbA1c was 2.10, of insulin,
8.94, of glucose, 1.73, and of HOMA-IR, 7.83. All ORs were statistically
significant. The areas under the receiver operating characteristics
curves for metabolic syndrome were 0.670 (across HbA1c values) and 0.770
(across insulin values), and, for insulin resistance, 0.647 (HbA1c) and
0.995 (insulin). Among non-metabolic syndrome patients, a small insulin
elevation identified risk factor clustering.
Conclusions
HbA1c and specially insulin levels were associated with metabolic
syndrome criteria, their clustering, and insulin resistance. Insulin
could provide early information in subjects prone to develop metabolic
syndrome.M. Laclaustra was supported in part by grant FIS CP08/00112 from

MIGRATE: mobile device virtualisation through state transfer
Delegation of processing tasks to the network has moved from cloud-based schemes to edge computing solutions where nearby servers process requests in a timely manner. Virtualisation technologies have recently given data cloud and network providers the required flexibility to offer such on-demand resources. However, the maintenance of close computing resources presents a challenge when the served devices are on the move. In this case, if processing continuity is desired, a transference of processing resources and task state should be committed to maintain the service to end devices. The solution here presented, MIGRATE, proposes the concept of virtual mobile devices (vMDs) implemented as Virtual Functions (VxF) and acting as virtual representatives of physical processing devices. vMDs are instantiated at the edge of the access network, following a Multi-Access Edge Computing (MEC) approach, and move across different virtualisation domains. MIGRATE provides seamless and efficient transference of these software entities to follow the real location of mobile devices and continue supporting their physical counterparts. Software Defined Networks and Management and Operation functions are exploited to “migrate” vMDs to new virtualisation domains by forwarding data flows to the former domain until the new one is prepared, while a distributed data base avoids the transference of data. The solution has been deployed in a reference vehicular scenario at the Institute of Telecommunications Aveiro premises within the 5GINFIRE European project. In particular, the system has been evaluated under different virtualisation domains to study the operation of the migration approach in a vehicular monitoring scenario. The results validate the system from the application viewpoint with a Web monitoring tool, and the migration of the digital twin provided as VxF is analysed attending to the modification of data flows, indicating a seamless transition between virtualisation domains in a timely manner.publishe
Meta-Analysis Design and Results in Real Life: Problem Solvers or Detour to Maze. A Critical Review of Meta-Analysis of DAPT Randomized Controlled Trials.
Therapeutic strategies - such as duration of dual antiplatelet therapy after coronary artery stenting - usually generate a large quantity of meta-analyses. The meta-analyses that include the same randomized clinical trials should produce similar results. Our aim in the study is to analyze the quality and to compare the results of meta-analyses focused on a controversial topic such as dual antiplatelet therapy after percutaneous coronary intervention.
We searched all published meta-analyses published up to November 2015 (near DAPT trial publication) selecting those that included the same randomized clinical trials comparing patterns of briefer versus longer-term double antiplatelet therapy.
Seventeen meta-analyses achieved our selection criteria. Of the seventeen analyzed, we identified seven (41.1%) based on the same ten randomized clinical trials (RCTs), yet their results varied widely. Many of the meta-analyses differed in only some minor aspect of the design (i.e. eligible studies, length of comparators and statistical methods used). Some authors differed in the number of patients participating in RCTs and even, despite reviewing the same underlying trials, only 2 of the 7 meta-analyses included the same number of patients.
Meta-analyses around cardiovascular, all-cause or non-cardiovascular death differ frequently. In the DAPT duration setting, several meta-analyses have been recently published based on the same data, presenting several issues making it difficult to determine clear recommendations on certain points.IN receives research funding from Astrazeneca; has received minor

Ice Cream: new virtual reality tool for the assessment of executive functions in children and adolescents: a normative study
This study focuses on the obtention of normative data for participants between 8 and 16 years old who were administered the Ice Cream test, a virtual reality tool designed to evaluate executive functions. The normative sample comprised n = 821 participants (49% female), with an age range of 8 to 16 years old, recruited across nine different testing sites in Spain. Experienced evaluators in psychological assessment, recruited and trained by the developer of the test, administered the test to the recruited sample. An empirical analysis of Ice Cream identified three factors, namely planning, learning and flexibility. Descriptive normative groups by age and gender were initially provided. A homoscedasticity analysis by gender showed no statistically significant differences between male and female participants. Cluster analysis by age suggested the creation of different age groups, respectively, 8 to 11 and 12 to 16 in Planning and Flexibility, and 8 to 9 and 10 to 16 in Learning, and subsequently, descriptive data for the established age groups per factor are shown. A confirmatory factor analysis showed the suitability of the 3 factors established as measured of three differentiated executive functions. Complementary data on the validity and reliability, and internal consistency of the scales are provided. Obtained normative data are relevant for evaluating executive functions in children and adolescents in a more ecological way. Further studies are needed to determine sensitivity and specificity of Ice Cream VR test to measure executive functions in different clinical populations
