Abstract
Introduction
In vitro studies demonstrated that targeted deletion of the transcription factor encoding gene TCF21, was associated with vascular smooth muscle cell disruption. Recent research showed that TCF21 expression contribute to fibrous cap formation, preventing heart attacks.
Purpose
Analyse the TCF21 rs12190287 gene and evaluate its association with atherosclerosis severity measured according to the coronary angiogram patients´ data. Methods: Prospective study with 1,639 coronary artery disease (CAD) patients (mean age 53.4 ± 7.8 years). Two age groups (< 55 and > 55 years) were stratified and analyzed. TCF21 rs12190287 G > C was genotyped in all patients. The severity of CAD was graded according to the number of obstructed coronary arteries with at least 70% narrowed lumen. Chi-squared tests and multivariate logistic regression models were analysed.
Results
The CC genotype was associated with > 70% obstructive lesions (vascular disease rate, 48.1%). Contrariwise, the GG wild genotype was associated with less severe obstructive disease (19.5%) (P = 0.003). When we stratified the TCF21 genotypes per age group (55 years), the CC genotype in the younger group had more obstructed disease (47.4%) when compared with GG (18.8%) (P = 0.012), but this effect was not significant in the older group. Multivariate analysis (logistic regression) showed that the CC genotype had a high risk of multivessel coronary disease (OR = 2.88; P = 0.001) than GG.
Conclusion
This work shows that the TCF21 wild genotype protects against CAD severity. In contrast, the CC genotype is associated with an increased risk of CAD severity.

Abstract
Abstract
Introduction
The new European SCORE2 estimates the combined risk of fatal and non-fatal cardiovascular (CV) events, in contrast with SCORE's use for CV mortality only. Although controversial, several studies point out that Coronary Artery Calcification (CAC) scoring could improve CV risk stratification in primary prevention.
Purpose
Assess the impact of including CAC score to the new SCORE2 in MACE prediction and CV risk stratification in an asymptomatic Portuguese population.
Methods
The new SCORE2 was calculated in a population-based cohort of 1,014 individuals (mean age 58.6±8.5 years) without known CV disease and diabetes. Population was stratified into three SCORE2 risk categories (low-, moderate- and high-risk). According to the Hoff's nomogram, CAC score was categorized into: low CAC (0≤CAC<100 or P<50); moderate CAC (100≤CAC<400 or P50–75) and high or severe CAC (CAC≥400 or P>75). Kaplan-Meier survival curves were estimated and a multivariate regression analysis predicted the MACE risk for both scores. C-statistic methodology evaluated the ability of CAC when added to the SCORE2 model in MACE prediction.
Results
Kaplan-Meier curves showed that the highest categories of both scores presented a worst survival. Cox regression analysis showed that the highest categories of both CAC and SCORE2 remained in the equation with an increased MACE risk (HR) of 3.69 (p=0.008) and 9.87 (p=0.005), respectively, when compared with the lowest categories. C-statistic demonstrated that the predictive value for MACE increased from 0.668 (SCORE2 model) to 0.787 when CAC was included (p=0.012), showing a better predictive and discriminative capacity for MACE.
Conclusions
Our results highlight the importance of adding CAC score to SCORE2 in primary prevention to improve cardiovascular risk stratification and MACE risk prediction. Larger prospective multicenter cohorts with longer follow-up should reproduce and validate these findings.

Abstract
Abstract
Introduction
Lipoprotein(a) [Lp(a)] is an LDL-like molecule composed of a part of apolipoprotein(a) bounding covalently to apolipoprotein B-100. High plasma Lp(a) levels were associated with MACE in stable CAD patients. Recent research shows contradictory results in stable CAD patients with high Lp(a) plasmatic levels and impaired glucose metabolism in MACE occurrence.
Purpose
Investigate whether high Lp(a) levels were associated with MACE in CAD patients with impaired glucose metabolism, at an extended follow-up.
Methods
A prospective cohort of 1,127 CAD patients with impaired glucose metabolism (pre-diabetes and diabetes) was observed during 4.9±3.4 years. Pre-diabetes was considered when fasting plasma glucose ranged from 5.6 to 6.9 mmol/L, or hemoglobin A1c levels ranging from 5.7 to 6.4%. Lp(a) levels ≥30 mg/dL were considered high. Bivariate and multivariate Cox regression analysis evaluated the risk of Lp(a) ≥30 mg/dL for MACE occurrence. Kaplan-Meier curves estimated the survival probability for high and low Lp(a) levels.
Results
Of the patients with Lp(a) levels ≥30, 44.4% presented MACE and 32.0% had no MACE (p<0.0001). Cox regression analysis with smoking, hypertension, dyslipidemia, physical inactivity and kidney failure (creatinine clearance <60 mL/min) showed that high Lp(a) remained in the equation as an independent risk factor for MACE (HR=1.24; p=0.031). The Kaplan-Meier showed, at 10-year' follow-up, a better survival in the group with lower Lp(a) levels (p=0.023).
Conclusion
Our study demonstrated that high Lp(a) levels were an independent predictor of MACE and cardiovascular mortality in a CAD population with impaired glucose metabolism. Lp(a) measurement may help further risk stratification for diabetes and pre-diabetes patients suffering CAD. With the recent development of drugs that selectively lower Lp(a) levels, this marker can become a clinical target for reducing CVD risk.

Abstract
Abstract
Introduction
Coronary artery calcium (CAC) score has emerged as the most predictive cardiovascular risk marker in asymptomatic individuals, capable of adding prognostic information beyond the traditional risk factors (TRF). Genetic risk score (GRS) significantly improves cardiovascular genetic risk assessment at the individual level providing a more personalized measure of disease risk.
Purpose
We intend to evaluate which tool, added to TRF, is more valuable in predicting and discriminating cardiovascular events and death (MACE) - GRS or CAC score?
Methods
We performed a prospective study with 1153 participants without CAD history at baseline (74.2% male, age 51.7±8.3 years) during a mean follow-up of 5.4±3.4 years. We selected 14 SNPs previously associated with CAD presenting a risk (HR) for cardiovascular events ≥1. A weighted GRS was calculated, as the sum of these 14 risk alleles weighted by the corresponding effect size in prognostic (HR), and subsequently, subdivided into tertiles. CAC (Agatson) score was calculated in all participants and categorized into: low CAC (0≤CAC<100 or P<50); moderate CAC (100≤CAC<400 or P50–75) and high or severe CAC (CAC≥400 or P>75). Two models were created with TRF baseline (hypertension, smoking, body mass index, dyslipidemia, diabetes, chronic kidney disease, physical inactivity): 1) plus wGRS and 2) plus CAC score categories. Cox Regression Analyses and C-statistic assessed the predictive and discriminative capacity of both models.
Results
For model 1, Cox regression presented an HR of 4.292 for TRF (p=0.007) and 2.713 for 3rd tertile of wGRS (0.036). A modest but statistically significant improvement in MACE discriminative capacity was verified by adding wGRS to TRF, increasing the C-statistic from 0.617 to 0.687 (ΔC=0.070; p=0.013). On the other hand, model 2 better discriminated MACE when the CAC score (C-statistic = 0.765) was added to TRF (ΔC=0.148; p=0.001). Cox regression displayed an HR of 4.42 for TRF (p=0.015) and an HR of 4.55 for high-risk CAC score (p=0.001).
Conclusion
Our results suggest that adding a polygenic risk score to conventional risk factors provides a modest improvement in the discrimination of first-onset MACE. However, the CAC score added to the traditional model allows better discrimination of MACE compared to wGRS. CAC score could be helpful for MACE prediction, at least in individuals belonging to the higher genetic risk group. However, further investigation is required before clinical implementation.

Abstract
Abstract
Introduction
The new SCORE2 provides risk estimates for the combined outcome of fatal and non-fatal cardiovascular disease (CVD) events, in contrast with SCORE's use for CVD mortality only. Genetic predisposition to CVD is not considered in SCORE2 for prevention and treatment.
Purpose
Evaluate the impact of adding a Genetic Risk Score (GRS) to the new European SCORE2 in MACE prediction and estimate the additional value in cardiovascular risk stratification in an asymptomatic Portuguese population.
Methods
A prospective study was performed in a population-based cohort of 1,100 individuals without known CVD and diabetes (mean age 53.3±6.9 years). For all included participants, SCORE2 was calculated and three risk categories were considered: low-, moderate- and high-risk. A 33-SNP GRS was constructed and two groups were analyzed: lower and higher than the GRS median. Kaplan-Meier survival curves were created and a Cox regression model was performed with the two scores to assess MACE risk. C-statistic methodology compared the model between SCORE2 solely and SCORE2 plus GRS.
Results
After Kaplan-Meier analysis for MACE occurrence, the high categories of SCORE 2 and GRS showed worst survival when compared to the lower categories (p<0.0001). Cox regression presented an HR of 8.528 (p=0.001) for high-risk SCORE2 and an HR of 4.520 (p<0.0001) for GRS higher than the median. C-statistic demonstrated that the SCORE2 predictive value was 0.678, increasing to 0.792 when GRS was included (p=0.0005).
Conclusions
In this work, combining SCORE2 with multiple genetic loci gathered into a GRS, improved the identification of patients with the worst prognosis. This new tool may be of great utility in risk stratification in primary prevention. Larger prospective multicenter cohorts with longer follow-up should reproduce and validate these findings.

Abstract
Abstract
Introduction
TCF21 is a member of the basic helix-loop-helix (bHLH) transcriptor factor family, being critical for embryogenesis of the heart. It regulates epicardium-derived cells differentiation into smooth muscle (SMC) and fibroblast lineages. The biological roles of TCF21 in epicardial fate determination and the progression of atherosclerosis remains a controversial issue.
Purpose
Investigate the impact of the TCF21 rs12190287 G>C variant on the prognosis of a coronary artery disease (CAD) cohort.
Methods
A prospective study was performed with 1,713 CAD patients (mean age 53.3±7.8; 78.7% male) surveyed in terms of MACE occurrence in an extended follow-up of 5.0±4.3. TCF21 rs12190287 was genotyped and analysed using the dominant model (GC+CC) and, subsequently, compared with the wild-type GG to evaluate the survival probability by Kaplan-Meier. A Cox regression analysis with all the risk factors and genetic models was performed to assess the independent variables associated with the prognosis of CAD patients.
Results
GG wild genotype was present in 9.5% of the population, GC in 43.2% and the risk genotype CC accounted for 47.3% of the CAD patients. The dominant model GC+CC showed a worse survival throughout the follow-up period. After multivariate Cox regression analysis, this model remained in the equation as an independent risk factor for MACE occurrence with an HR of 1.41 (p=0.033) together with multivessel disease, physical inactivity, chronic kidney disease (CKD) and diabetes.
Conclusion
TCF21 rs12190287 is a risk factor for prognosis in our population. The role of this gene may influence fundamental SMC processes in response to vascular stress, accelerating atherosclerosis progression and may represent a target for future therapies.

Abstract
Abstract
Introduction
Coronary artery disease (CAD) is a dynamic inflammatory disease caused by atherosclerosis. GWAS showed that ZNF259 rs964184 encoding zinc finger protein (ZPR1) was associated with dyslipidemia and CAD. Recent research found that ZPR1 transcription is up-regulated in the brain of mice fed a high-fat diet, influencing the cell cycle, apoptosis, and RNA metabolism in neurons. This process at the heart vessels may increase oxidative stress and CAD.
Purpose
Study the association between the ZNF259 rs964184 C>G polymorphism with dyslipidemia and CAD susceptibility in a Portuguese population.
Methods
A case-control study was performed with 3,160 individuals, namely 1,723 CAD patients (mean age 53.3±7.9; 78.7% male) and 1,437 controls (mean age 52.8±7.8; 76.3% male). Participants were stratified into two age groups (<45 and >55 years). ZNF259 rs964184 C>G was genotyped and analysed using the dominant model (CG+GG vs CC). Multivariate logistic regression was performed in both age groups to investigate whether rs964184 polymorphism was associated with dyslipidemia and CAD susceptibility.
Results
The dominant model of ZNF259 was associated with dyslipidemia (OR=1.85; 95% CI: 1.22–2.79; p=0.003) and CAD (OR=1.46; 95% CI: 1.02–2.09; p=0.036) in the younger population under 45 years. In the >55 years group, this model was associated with dyslipidemia (OR 1.46; 95% CI: 1.06–2.01; p=0.020) but not with CAD. After multivariate logistic regression, the CG+GG remained an independent risk factor for CAD susceptibility only in the population <45 years (OR=1.60; 95% CI: 1.03–2.50; p=0.037).
Conclusion
ZNF259 rs964184 is a risk factor for dyslipidemia in the whole population. Dyslipidemia may up-regulate ZPR1 transcription, enhancing the vulnerability of coronary endothelial cells to both oxidative stress and inflammatory response, increasing CAD susceptibility. This mechanism seems more relevant at the cellular level in young patients representing a possible prophylactic and therapeutic target, especially in this age group.

Abstract
Abstract
Genome-wide association studies have identified several loci linked to coronary artery disease, and coronary atherosclerosis progression. However, the impact of the genetic contribution to MACE occurrence in sub-clinical atherosclerosis is unknown.
Purpose
This study intended to assess the relationship between a set of single nucleotide popymorphism (SNP) associated with CAD by GWAS and the MACE occurrence in an asymptomatic population. After that evaluate whether a wGRS englobing these variants is useful to estimate the prognostic.
Methods
Prospective study performed in an asymptomatic cohort from GENEMACOR population-based sample of 1114 subjects aged 51.7±8.3, 74.2 male, without prior coronary artery disease. Coronary Artery Calcium (CAC) score was assessed by coronary computed tomography (Agatston method), and two categories were considered 1–99 and >100. 33 SNP were evaluate to assess the significantly associated with prognostic. A weighted (wGRS) was constructed as the sum of the risk alleles weighted by the corresponding effect size (HR). Cox regression analysis adjusted for the main risk factors, calcium score (CAC) and wGRS to assess the risk of MACE during follow-up. Kaplan Meier assessed the survival.
Results
Of the studied 33 SNPs previously associated with CAD (GWAS), only 4 presented the significant association with MACE occurrence: CDKN2B-AS1 rs4977574, HNF4A rs1884613,
APOE rs7412/rs429358A and GJA4A rs 618675. After Cox regression analysis the wGRS remained in the equation (HR=2.834); p=0.012, together with CAC score (HR 3.35); p=0.012; diabetes (HR=2.398); p=0.032 and age (HR=1.056; p=0.049. WGRS above the median presented a worst survival rate (p=0.006).
Conclusion
The wGRS englobing: CDKN2B-AS1 rs4977574, HNF4A rs1884613, APOE rs7412/rs429358A and GJA4A rs 618675 is independently associated with cardiovascular events in an asymptomatic population. CDKN2B-AS1 rs4977574 gene expression modulates the progression and severity of vascular calcification in vascular smooth muscle cells (VSMCs), HNF1α-AS1 is an important regulatory molecule in cancer biology and cardiovascular disease (its expression may regulate VSMCs, and high expression promotes atheroprotection). More research is crucial for understand prognosis in asymptomatic population.

Abstract
Abstract
Background
The coronary calcium score has been increasingly used to stratify and predict cardiovascular risk, particularly in low and intermediate-risk persons. Understanding which determinants have more impact on coronary calcium score level, could lead to the development of new stricter preventive measures for reducing coronary artery calcification (CAC) and, consequently, cardiovascular risk.
Purpose
Our study aimed to investigate the impact of the traditional risk factors (TRFs) on the CAC score level and if there is a different association between this TRFs and CAC score degrees, in an asymptomatic population.
Methods
The study cohort comprised 1,122 consecutive asymptomatic individuals without known coronary artery disease (CAD) belonging to the healthy controls of GENEMACOR study and referred for computed tomography for CAC scoring assessment. The traditional risk factors considered were (1) current cigarette smoking, (2) dyslipidemia, (3) diabetes mellitus, (4) hypertension and (5) family history of coronary artery disease. According to the Hoff's nomogram, 3 categories were created: low CAC (0≤CAC<100 and P<50); moderate CAC (100≤CAC<400 or P50–75) and high or severe CAC (CAC≥400 or P>75). We evaluated the association of the different TRFs with these levels of CAC score (Chi-square test). Finally, we performed a logistic regression model adjusted for all significant TRFs selected in the bivariate analyses.
Results
Smoking was significantly associated with high levels of CAC score, 28.4% vs 21.7%; p=0.038 as well as hypertension, 58.8% vs 45.6%; p=0.001, type 2 diabetes 21.1% vs 9.6%; p<0.0001, dyslipidemia, 73.0% vs 66.1%; p=0.057. Family history did not show a significant association with CAC (p=0.717). Then, we constructed a logistic regression model adjusted the significant risk factors in previous analysis. The final multivariate analysis, selected as independent predictors of high CAC: Type 2 diabetes; OR=2.309; 95% CI 1.533–3.479; p<0.0001, hypertension; OR=1.627; 95% CI 1.185–2.233; p=0.003, and smoking, OR=1.565; 95% CI 1.102–2.222; p=0.012.
Conclusions
In this study, well-known and modifiable cardiovascular risk factors are associated with high calcium score levels. However, hypertension and diabetes seem to be preferentially associated with higher CAC scores, while tobacco, although it has a significant association, seems to be not so strong as diabetes and hypertension. This concept may mean that smoking has its primary role in plaque instability and not so much in the growing and calcification of plaques.

Abstract
Abstract
Background
Hepatocyte nuclear factor4 A (HNF4A) gene was considered by GWAS associated with atherosclerosis and CAD susceptibility. Loss-of-function mutations in human hepatocyte nuclear factor 4α (HNF4α), a transcriptor factor encoded by the HNF4A gene, are associated with maturity-onset diabetes of the young and lipid disorders. However, the mechanisms underlying the lipid disorders are poorly understood.
Aim
We propose identifying the genetic predisposition to atherosclerosis progression and events occurrence or regression and better prognosis, through a cohort study from GENEMACOR population.
Methods
We investigated a cohort of 1,712 patients who underwent coronary angiography with more than 70% stenosis of at least one main coronary vessel. 33 SNPs associated with the risk of CAD in previous GWAS were genotyped by TaqMan assays methodology. We evaluated the best genetic model associated with CAD prognosis (events) with a 95% CI in bivariate analysis. The hazard function was performed by a Cox survival regression model adjusted for age, sex, type 2 diabetes, hypertension, and hypercholesterolemia, to evaluate their relationship with the event's incidence. Finally, we constructed Kaplan–Meier cumulative-event curves for the significant genetic variants.
Results
Our evaluation revealed a SNP paradoxically associated with protection from atherosclerosis progression and events occurrence: rs1884613 C>G in the HNF4A gene on chromosome 20 dominant model [OR=0.653; 95% CI (0.522–0.817); p=0.0002]. Cox survival regression model showed a CAD protective effect of HNF4A with a Hazard ratio (HR) of 0.771; p=0.007. The Kaplan-Meier cumulative event analysis disclosed that the CG+GG vs CC genotype of rs1884613 HNF4α was associated with a better prognosis (Breslow test, p=0.004) at the end of the follow-up.
Conclusion
We identified, in this study, one SNPs paradoxically associated with a better CAD prognosis rs1884613 in HNF4A. The HNF4A gene variants could induce loss of HNF4α function, modifying and modulating hepatic lipase and lipid metabolism conferring a beneficial effect on atherosclerosis progression and events occurrence.

Abstract
Abstract
Introduction
Epicardial adipose tissue (EAT) volume can be noninvasively detected by CT and has been suggested to predict major adverse cardiovascular events (MACE). Framingham Risk Score is one of a number of scoring systems used to determine an individual's chances of developing cardiovascular disease, hence identifying who is most likely to benefit from prevention.
Objectives
The purpose of this study was to determine net reclassification improvement (NRI) and improved risk prediction based on EAT volume, in comparison to a traditionally known cardiovascular risk score, such as the Framingham.
Methods
895 asymptomatic volunteers were prospectively enrolled in a single Portuguese center (mean age 51.9±7.7, 78.5% male) and underwent a median follow-up time of 3.7 years (IQR 5.0). EAT volume was measured by Cardiac Computed Tomography (CCT) using a modified simplified method. For NRI assessment, EAT volume as a continuous variable was added to the Framingham Risk Score.
Results
After 3.7 median years of follow-up, 27 patients developed a MACE. Using NRI, the net proportion of events (netNRIe) that assigned a higher risk was 33.3% (better reclassified), and the net ratio of non-events (netNRIne) was 24.7%, resulting in a net reclassification index (netNRI) of 58.0%. When the new marker was included in the model, 58.0% of patients were better reclassified. In our work, a total of 33.3% of patients who suffered events (n=27) were correctly reclassified and assigned a higher risk.
Conclusion
EAT volume results in a high reclassification rate in an asymptomatic, low-risk population, demonstrating the benefit of this marker beyond traditional risk assessment models. Our study supports its application, especially in carefully selected individuals.

Abstract
Abstract
Background
Metabolic syndrome (MetS) is a clinical condition composed of metabolic and cardiovascular risk factors, such as abdominal obesity, hyperglycemia, dyslipidemia and hypertension. Many patients with MetS suffer major adverse cardiovascular events (MACE) that are not adequately identified by traditional risk assessment, suggesting the need for early detection of subclinical coronary heart disease to identify those at high-risk. Coronary artery calcification (CAC) screening has added utility in categorizing patients with low, intermediate and high cardiovascular risk.
Purpose
Evaluate the prognostic role of CAC score in asymptomatic population patients with metabolic syndrome in cardiovascular events risk prediction.
Methods
A total of 1,122 asymptomatic individuals without known coronary heart disease, enrolled from GENEMACOR study, were followed for a mean of 5.3±3.4 years for the primary endpoint of all-cause of cardiovascular events. All were referred for computed tomography for the CAC scoring assessment. According to the Hoff's nomogram, 3 categories were created: low CAC (0≤CAC<100 or P<50); moderate CAC (100≤CAC<400 or P50–75) and high or severe CAC (CAC≥400 or P>75). In a subgroup of 507 individuals with MetS and 615 controls, CAC values were compared by T-student and association of CAC severity with events occurrence was evaluated. Finally, a logistic regression model adjusted for CAC severity was performed in patients with MetS.
Results
Among our population, the extent of CAC differs significantly between men and women in the same age group. Patients with Mets (23.2%, n=115) had higher CAC scores than controls (219.0±486.0 vs 115.8±370.8, p<0.0001). In this cohort, with higher CAC scores, 46.7% vs 22.5% had MACEs (p=0.049) during the follow-up. The logistic regression analysis revealed that CAC≥400 is a MACE predictor (OR=4.326, CI 95% 1.241–15.080, p=0.021) in patients with MetS.
Conclusion
Our results point to the importance of the inclusion of CAC screening in patients with MetS to further stratify those patients that, despite tight control of cardiovascular risk factors, may benefit from more intensive therapies. This tool is a useful and straightforward method that could have a significant impact on the prognosis of future cardiovascular disease in patients with MetS.

Abstract
Abstract
Introduction
Epicardial adipose tissue (EAT) is an emerging cardiovascular risk marker. It has been suggested to be an inflammatory mediator with a role in subclinical atherosclerosis and coronary artery disease. However, its prognostic relevance in hard clinical outcomes remains thoroughly unexplored in the literature.
Purpose
Evaluate the prognostic relevance of EAT, regarding the occurrence of major adverse cardiovascular events (MACE) in an asymptomatic population.
Methods
895 asymptomatic volunteers were prospectively enrolled in a single Portuguese center (mean age 51.9±7.7, 78.5% male) and underwent a median follow-up time of 3.7 years (IQR 5.0). EAT volume was measured by Cardiac Computed Tomography (CCT) using a modified simplified method. Participants were distributed into two groups, above and below the EAT-volume median. We compared both groups regarding the occurrence of MACE through univariate analysis, Kaplan-Meier Survival curves and log-rank test. Association to subclinical atherosclerosis was addressed using correlation between EAT volume and calcium score (Agatson).
Results
There is a strong correlation between EAT volume and calcium score (r=0.205, p<0.0001), sustaining that it may play an important role in mediating coronary artery disease and subclinical atherosclerosis. Patients with higher EAT volume, were exposed to higher occurrence of MACE on follow-up [70.4% (19 of 27) vs 49.4% (429 of 868), p=0.032] with a clearer separation of the curves after 5.7 years.
Conclusion
In an asymptomatic population, EAT volume seems to be related to subclinical atherosclerosis and to the occurrence of adverse cardiovascular events on long-term follow-up. Our study addresses some unanswered questions, such as the prognostic relevance of EAT as an emerging cardiovascular risk marker.

Abstract
Abstract
Background
The development of personalized susceptibility profiles based on genetic information to aid prediction, early detection and prevention of type 2 diabetes (T2D) with potential clinical application, begins to awaken interest in the scientific community. However, its clinical translation is controversial.
Objective
Evaluate the clinical utility of a genetic risk score (GRS) created with the GWAS-derived genetic variants associated to T2D to predict and discriminate the susceptibility to Type 2 diabetes, in a Southern European population with and without T2D.
Methods and results
We studied through a case-control with 3,139 subjects (772 with T2D and 2,367 without) the usefulness of implementing a GRS in clinical practice. We constructed a multiplicative GRS (mGRS) calculated using 10 SNPs of genetic loci robustly associated to T2D (HNF4A rs1884613, IGF2BP2 rs4402960, PPARG rs1801282, TCF7L2 rs7903146, SLC30A8 rs1326634, MC4R rs17782313, ADIPOQ rs266729, FTO rs8050136, TAS2R50 rs1376251 and APO E rs7412 and rs429358), to evaluate the prediction and discrimination of T2D. Two logistic regression models were performed the first with age, sex and BMI. The second with these three risk factors plus hypertension, LDL >130mg/dl and physical inactivity. Logistic regression models, receiver operating characteristic analyses (ROC curve) were used. Each model was analysed individually and added with mGRS to calculate the area under the ROC curve (AUC), which may be considered a global estimate of each model's predictive power. The inclusion of GRS in the first model increased the discriminative power of T2D (AUC=0.669 to 0.692; p<0.0001. In the second model, the increase was AUC=0.712 to 0.729; p<0.0001.
Conclusions
Adding genomic information to traditional models improves the ability to predict and discriminate type 2 Diabetes slightly, compared to traditional models alone. Nevertheless, this increase is not sufficiently robust for translation in clinical practice. However, clinicians should be conscious that T2D genetic research is experiencing a dramatic revolution and stay optimistic that these innovative studies translate into improved care for diabetic patients.

Abstract
Abstract
Background
Traditional and clinical risk factors are indicators of atherosclerosis over time and strong independent predictors of cardiovascular events, but it is unknown whether other genetic markers could provide information about the evolution of atherosclerotic coronary artery disease (CAD).
Objective
We propose identifying the genetic predisposition to atherosclerotic plaque progression and events occurrence, through a study cohort from GENEMACOR study population.
Methods
We performed a study with a cohort of 1,712 patients who underwent coronary angiography with more than 70% stenosis of at least one main coronary vessel, during a mean follow-up of 5 years (amplitude range 20 years). 33 SNPs associated with risk of CAD in previous GWAS, were genotyped by TaqMan assays methodology. The best model in the bivariate analysis at 95% CI with all genetic variants was generated, to investigate their association with prognostic and events occurrence. The hazard function at a set of confounding-variables was determined to evaluate their relationship with the event's incidence by the Cox survival analysis regression model. Finally, we constructed Kaplan–Meier cumulative-event curves for the significant variants.
Results
The analysis revealed two SNPs associated with the progression of atherosclerosis and events occurrence: rs12190287 G>C in the TCF21 gene on chromosome 10 (dominant model; OR=1.542; 95% CI 1.069 – 2.224; p=0.020) and the rs1333049 G>C in the CDKN2-AS1 gene on chromosome 9 (recessive model; OR=1.228; 95% CI 1.001 – 1.518; p=0.050). The Kaplan-Meier cumulative event curves in the TCF21 variant rs12190287 G> C showed that the GC+CC vs GG genotype was associated with a worse prognosis (log-rank test, p=0.016) and the CDKN2B-AS1 rs1333049 G> C revealed that the CC vs GG+GC genotype also presented severe prognosis and more events at the end of the follow-up period (log-rank test, p=0.046).
Conclusion
We have identified two SNPs associated with the prognosis of CAD, rs12190287 of TCF21 gene and rs1333049 of CDKN2-AS1 gene. Both are in non-coding enhancer regions and regulate transcriptional mechanisms shared among multiple CAD risk loci and could provide new insights into CAD's pathophysiology identifying core mechanisms for therapeutic intervention modulating the disease risk.

Abstract
Abstract
Introduction
Coronary Heart Disease (CAD) is a multifactorial disease, including environmental and genetic risk factors. Current smoking, dyslipidemia and diabetes have a significant impact in long- term mortality and morbidity. However, several genetic variants associated with CAD but not with traditional risk factors (TRFs) has been reported to improve prediction of events and extended mortality, in younger CAD people.
Aim
To evaluate the clinical utility of a GRS composed by variants from GWAS associated to CAD but not with TRF to predict life-long residual risk in patients under 55 years old and a low level of TRFs.
Methods
We conducted a prospective study with 573 consecutive patients aged <55 years presenting with AMI and a low level of TRFs (without diabetes and with LDL cholesterol >150 mg/ml). We analysed several biochemical markers and performed a GRS with variants not associated with TRFs (TCF21 rs12190287, CDKN2B-AS1 rs1333049, CDKN2B rs4977574, PHACTR1 rs1332844, MIA3 rs17465637, ADAMTS7 rs3825807, ZC3HC1 rs11556924, SMAD3 rs17228212 and GJA4 rs618675). We studied the GRS association with a primary composite endpoint of all-cause vascular morbidity and mortality including recurrent acute coronary syndrome (myocardial infarct and unstable angina), coronary revascularization (coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI), re-hospitalization for heart failure, ischemic stroke and cardiovascular dead.
Results
A total of 573 patients were studied and followed up for a mean of 4.7±4.0 years. There were 169 recurrent cardiovascular events. The GRS was sub-divided into terciles, verifying that patients in the third tercile (high risk) had a higher number of risk alleles. Compared with the low-risk GRS tercile, the multivariate-adjusted HR for recurrences was 1.520 (95% CI 1.011–2.286); p=0.044 for the intermediate-risk group and was 2.051 (95% CI 1.382–3.044); p<0.0001 for the high-risk group. Inclusion of the GRS in the model with TRFs alone (low risk) improved the C-statistic analysis (C-statistic = 0.030; p=0.004), cNRI (continuous net reclassification improvement) (30.8%), and the IDI (integrated discrimination improvement index) (0.022).
Conclusions
A multilocus GRS may identify young coronary disease patients with a low level of TRFs but at significant risk of long-term events recurrence. The genetic information may improve prediction discrimination, and reclassification over the conventional risk factors alone, providing better cost-effective therapeutic strategies.

Abstract
Abstract
Background
The risk for Coronary Artery Disease (CAD) can be estimated using different scores, such as the European SCORE (Systematic Coronary Risk Evaluation) scale or genetic risk score (GRS). The addition of GRS to the European SCORE may increase the precision of predicting MACE (Major Adverse Cardiovascular Events).
Purpose
This study aims to compare the European SCORE and the multiplicative genetic risk score (mGRS) in predicting MACE.
Methods and results
The study included 1110 asymptomatic individuals without known CAD from GENEMACOR prospective registry. We defined the primary endpoint of all-cause cardiovascular events.
The study population had mean age of 51.6 years, 74.1% male and had risk factors of diabetes (11.6%), dyslipidemia (67.5%), hypertension (48.1%) and smoking (22.9%). Using C-index methodology, mGRS score was superior to SCORE in predicting MACE (mGRS = 0.832 Vs SCORE = 0.615; p=0.014).
Conclusions
The mGRS score was superior to SCORE in predicting MACE in an asymptomatic and free of CAD population. Genetic information may improve cardiovascular risk stratification in primary prevention.

Abstract
Abstract
TCF21 is a member of the basic-helix-loop-helix (bHLH) transcriptor factor family, being critical for embryogenesis of the heart, kidney and spleen. TCF21 also regulates epicardium-derived cells differentiation into smooth muscle and fibroblast lineages.
Aim
Investigate the impact of TCF21 rs12190287 in the prediction and discrimination of CAD risk, individually or into a genetic risk score (GRS) formed by a set of 13 genetic variants.
Methods
We performed a case-control study with 3050 subjects (1619 coronary patients with 53.3±8 years; 78.9% male and 1431 controls with 52.8±8 years; 76.6% male) from GENEMACOR study. We investigated all traditional risk factors (TRF), as well as 13 genetic variants from GWAS with unknown pathophysiological pathway so far, including TCF21 (rs12190287), ZC3HC1 (rs11556924), PSRC1/SORTI (rs599839), PHACTR1 (rs1332844), MIA3 (rs17465637), SMAD3 (rs17228212), ZNF259 (rs964184), ADAMTS7 (rs3825807), CDKN2B (rs4977574), 9p21.3 (rs1333049), KIF6 (rs20455), PCSK9 (rs2114580) and GJA4 (rs618675). A multiplicative genetic risk score with these 13 genetic variants (m13GRS), was calculated. Subsequently, two logistic regressions were performed; primarily with all the TRF and all the genes individually and the second with TRF and m13GRS.
Results
The first multivariate analysis shows that, besides the strong association of the TRF with CAD risk (with smoking status on the top of the list, with an OR of 3.2; p<0.0001), TCF21 rs12190287 was the most significant variant from all the studied genetic set with a CAD risk of 1.5 (95% CI: 1.1–1.9; p=0.004), followed by the well-known genetic determinant CDKN2B rs4977574 (OR=1.4; 95% CI: 1.1–1.7; p<0.002) and ZC3HC1 rs11556924 (OR=1.3; 95% CI: 1.0–1.7; p=0.034). When GRS is included to the model, all the TRF remain in the equation by the same order, and the m13GRS persisted as an independent predictor for CAD risk (OR=1.7; 95% CI: 1.4–2.0; p<0.0001).
Conclusion
TCF21 rs12190287 is a risk factor for CAD in the Portuguese population, either individually or incorporated in a m13GRS. TCF21 risk is independent from TRF. In the future, TCF21 can provide a new clues to identify patients at high cardiovascular risk and become a potential target for gene therapy.

Abstract
Abstract
Background
The prognostic impact of the timing where new-onset Atrial Fibrillation (AF) occurs in Acute Coronary Syndrome (ACS) patients isn't well studied.
Objective
Evaluate the predictors and prognostic impact of early-onset AF (EAF) and late-onset AF (LAF) in ACS patients.
Methods
We analysed 17016 patients with ACS enrolled in a national multicenter registry from October 2010 to January 2019. Patients with history of valvular disease, valve replacement, AF present at hospital admission or those who died in the first 48 hours were excluded. EAF was defined as AF in the first 48 hours of hospitalization and LAF after 48 hours. The primary endpoint was a composite of death and readmission from cardiovascular causes at 1 year.
Results
The mean age was 65±13 years; 74% were males and 42% had STEMI). 324 (1.9%) had EAF and 344 (2.0%) had LAF.
The predictors of EAF were age ≥75 years (OR 2.04, 95% CI 1.53–2.70, p<0.001); history of heart failure (OR 1.82, 95% CI 1.09–3.02, p=0.022), STEMI diagnosis (OR 2.74, 95% CI 2.06–3.61, p<0.001), admission Killip class (KK)≥2 (OR 2.70, 95% CI 1.98–3.69, p<0.001).
The predictors of LAF were age ≥75 years (OR 3.15, 95% CI 2.36–4.19, p<0.001), history of stable angina (OR 1.42, 95% CI 1.06–1.90, p=0.018), cerebrovascular disease (OR 1.68, 95% CI 1.14–2.46, p=0.008), COPD (OR 2.33, 95% CI 1.58–3.44, p<0.001), STEMI diagnosis (OR 2.31, 95% CI 1.77–3.03, p<0.001), admission KK ≥2 (OR 2.06, 95% CI 1.54–2.76, p<0.001) and stress hyperglycemia (OR 1.54, 95% CI 1.15–2.05, p=0.003)
In STEMI patients only those with LAF had higher symptoms time (245 (IQR 165–400) minutes vs 284 (IQR 200–425) min; p=0.02).
During hospitalization, LAF patients had a worse prognosis with a higher rate of heart failure, re-infarction, stroke, major bleeding and death (Table 1).
In the follow-up, in multivarite analysis, only LAF was a predictor of the primary endpoint (EAF: HR 0.79, 95% CI 0.50–1.25, p=0.314; LAF: HR 1.45, 95% CI 1.05–2.00, p<0.025).
Complications during hospitalization No AF EAF LAF p Death 1.3 6.5 12.5 <0.001 Heart Failure 11.4 38.3 50.3 <0.001 Re-enfarction 1.0 0.9 3.5 <0.001 Stroke 0.5 0.9 3.8 <0.001 Major bleeding 1.3 4.3 4.1 <0.001
Kaplan Meier curve
Conclusion
Patients with EAF and LAF have different characteristics and outcomes with LAF patients having a worse in-hospital and long term prognosis.

Abstract
Abstract
Background
Stress hyperglycaemia (SH) is a transient elevation of blood glucose (Gc) associated with acute, severe illness. However, the presence of hyperglycemia does not necessarily indicate the presence of SH, thus, the relative acute Gc rise provided by the ratio between acute and chronic Gc levels (A/C ratio) could more accurately represent so.
Objective
We investigated the association between the A/C ratio with in-hospital and long term prognosis in Acute Coronary Syndrome (ACS) patients.
Methods
Retrospective study of patients with ACS included in a single center between Jan/2012 and Dec/2017. Gc and HbA1c levels were measured at hospital admission. To calculate the A/C ratio the published formula 28.7×HbA1c-46.7 to estimate chronic Gc was used. The primary endpoints were a composite of in-hospital death and Killip class (KK) ≥III and a composite of infarction, stroke, heart failure and cardiovascular death (MACCE) in the follow-up.
Results
We included 404 patients (68±13 years; 72.8% males; 43.6% STEMI). The median A/C ratio was 1.07 (IQR 0.92–1.32). Patients in the highest tertile of the A/C ratio had a higher GRACE risk score (134±32, 139±38, 158±42; p<0.001); higher KK (≥II: 11%, 24%, 33%; p<0.001) and a lower ejection fraction (EF) (53±10%, 50±10%, 48±12%; p=0.003), than patients in the lower tertiles.
During hospitalization 9 (2.2%) patientss died and 48 (11.9%) had the primary endpoint. The incidence of the in-hospital primary endpoint increased with A/C ratio tertiles (4.4%, 8.2%, 23.0%; p for trend <.001), for which it showed a good predictive capability (AUC=0.72, 95% CI: 0.67–0.76). Using the Youden index the cut-off value of 1.31 for the A/C ratio was decided.
After a median follow-up of 34 months (IQR 19–51), 50 (13%) patients died and 84 (21.9%) had MACCE.
After adjusting for admission diagnosis, diabetes mellitus, GRACE and EF, an A/C ratio>1.31 was an independent predictor for the risk of death (HR 2.79, 95% CI: 1.17–6.65; p=0.021) and MACCE (HR 1.79, 95% CI: 1.09–2.93; p=0.020) in the follow-up.
Conclusion
In ACS patients, the A/C glycemic ratio increased with the severity of the index event and was a predictor of death and MACCE during the follow-up. It is readily available and provides valuable risk stratification and prognostic information.

Abstract
Abstract
Introduction
Previous research reported that LPA gene is a strong and independent predictor of CAD in non-diabetic patients but not in patients with type 2 diabetes. These results suggest that LPA gene might contribute less to CAD risk in patients with T2DM than in general population.
Objective
Investigate, in our population, the association between LPA gene CT variant and CAD risk among diabetic patients.
Methods
3050 individuals (1619 coronary patients and 1431 controls) were genotyped for LPA rs3798220 TT/CT. Pearson's chi-squared test was applied to evaluate the association between LPA variants and CAD, firstly, in the general population and, secondly, in the group of patients with T2DM (n=735). Multivariate logistic regression was performed with LPA CT variant and 6 traditional risk factors (TRF) (smoking, dyslipidemia, diabetes, hypertension, family history of CAD and physical inactivity) in both general and diabetic population.
Results
In total population, LPA CT variant was found to be strongly and significantly associated with CAD with an OR of 2.32 (95% CI: 1.56–3.45; p<0.0001). However, this association was less pronounced in the diabetic population with a CAD risk of 1.38 (95% CI: 0.56–3.43) without statistical significance (p=0.485). In the presence of 6 major TRF, multivariate analysis showed that LPA CT remained a strong and independent predictor of CAD risk (OR= 2.34; 95% CI: 1.52–3.62; p<0.0001). In diabetic population, LPA was no longer an independent predictor for CAD by multivariate analysis.
Conclusions
Our results show that the effect of LPA gene on CAD risk among diabetic patients might be different from that in the general population. Diabetes status is such a strong risk factor that may attenuate the genetic effects of LPA on CAD risk. This may indicate a complex role of Lp (a) and diabetes interaction in cardiometabolic diseases.

Type 2 Diabetes (T2D) is a risk factor for dysregulation of glomerular filtration rate (GFR) and albuminuria. However, it remains unclear whether this association is only causal. Genetic variants are inherited independent of potential confounding factors and represent a lifetime exposure.
Aim
Investigate whether the reduction of GFR is a direct consequence of T2D or there are other genetic mechanisms involved in the pathophysiology of the evolution to chronic kidney disease.
Methods
Cross-sectional study with a total of 2579 individuals was performed, of which 735 patients had T2D. Subjects were classified as `'diabetic” if they were taking oral anti-diabetic medication or insulin or if their fasting plasma glucose was higher than 7.0 mmol/l or 126 mg/dl. Within the diabetic group, we considered those with (n=63) and without (n=627) decreased GFR. GFR was calculated through the Cockcroft and Gault formula and decreased GFR was defined as GFR<60 ml/min/1.73m2. Twenty-four genetic variants associated with T2D, metabolic syndrome, dyslipidemia and hypertension were investigated for its impact on GFR, namely: MTHFR 677 and 1298; MTHFD1L; PON 55, 192 and 108; ATIR A/C; AGT M235T; ACE I/D; TCF7L2; SLC30A8; MC4R; ADIPOQ; FTO; TAS2R50; HNF4A; IGF2BP2; PPARG; PCSK9; KIF6; ZNF259; LPA; APOE; PSRS1. Risk factors for decreased GFR were also evaluated (essential hypertension, glycaemia >120 mg/ml, dyslipidemia, alcohol consumption, CAD diagnosis). A logistic regression was performed firstly with the risk factors solely; and secondly adding the genetic variants in order to evaluate the independent predictors of progression to renal failure in T2D.
Results
After the first multivariate logistic regression with all the risk factors for decreased GFR, only CAD remained in the equation, showing to be an independent risk factor for progression to renal failure, in T2D (OR=4.17; 95% CI: 1.64–10.59; p=0.003). In the second logistic regression, including risk factors and the genetic variants, only ZNF259 rs964184 showed an independent and significant association with the risk of decreased GFR (OR=3.03; 95% CI: 1.06–8.70; p=0.039).
Conclusion
This study shows that the variant ZNF259 rs964184 is associated with decreased kidney function, independently of other risk factors. This finding needs further investigation to clarify the genetic mechanism behind the association of rs964184 with decreased GFR, in Type 2 diabetes.

Abstract
Abstract
Introduction
Coronary artery disease (CAD) is a multifactorial process with substantial genetic contribution. However, genetic predisposition among patients with a different number of lifestyle factors and premature CAD, remains a complex and thoroughly unexplored topic.
Objective
To evaluate, in a young population, the importance of conventional risk factors as well as of a genetic risk score in the appearance of CAD.
Methods
A case-control study was conducted with 1075 patients from the GENEMACOR study population, under 50 years-old (555 cases, 86.8% male, mean age 44.1±4.9 years and 520 controls, 86.2% male, mean age 44.3±4.8 years). Univariate analysis addressed the association of different modifiable risk factors with premature CAD. Genetic risk score (GRS) was computed comprising 33 genetic risk variants in a multiplicative method. GRS was evaluated according to the number of traditional risk factors and risk for premature CAD was estimated and its independent predictive value estimated by logistic regression.
Results
72.6% of patients had ≥3 risk factors vs 31.2% of controls (p<0.0001). In comparison with having no risk factors (rf), patients with 1 rf had an OR of 2.79 (1.19–6.53; p=0.015), patients with 2 risk factors had a OR of 6.87 (3.03–15–57, p<0.0001) and patients with 3 modifiable risk factors had a OR of 24.17 (10.87–53.73, p<0.0001) – graph 1. In this young population, mean GRS level was consistently higher among patients with coronary artery disease comparing with a healthy population (0.6±0.6 vs 0.4±0.4, p<0.0001, respectively) – graph 2. GRS in multivariate analysis, proved to be an independent predictor for premature CAD (OR 1.71, CI95% 1.25–2.34, p=0.001).
Conclusion
In our population, GRS was an independent predictor for premature CAD. In young patients with ≥3 risk factors, genetics play a less decisive role in the development of CAD. Even in young patients, modifiable risk factors should be addressed aggressively as they may represent a higher burden than genetic predisposition itself.

Abstract
Abstract
Introduction
The complex interaction between genes and environmental factors contribute to individual-level risk of coronary artery disease (CAD), often resulting in premature CAD. The role for genetic risk scores in premature CAD is still controversial.
Objective
To evaluate the importance of conventional risk factors and of a genetic risk score in younger and older patients with coronary artery disease
Methods
From a group of 1619 pts with angiographic documented CAD from the GENEMACOR study, we selected 1276 pts admitted for ACS and analysed them in 2 groups (group A: ≤50 years, n=491 pts, 87.2% male, mean age 44±4.9 and group B: >50 years, n=785 pts, 75.2% male, mean age 57±4.2). Univariate analysis was used to characterize the traits of each group and we used ROC curves and respective AUCs to evaluate the power of genetics in the prediction of CAD, through a Genetic Risk Score (GRS).
Results
99.3% of the young patients had at least one modifiable risk factor, 18.4% had 2 modifiable risk factors and 75.2% had 3 or more modifiable risk factors. The pattern of risk factors contributing to CAD were different among groups: family history (A: 27.5%, B: 21.4%, p=0.015) and smoking habits (A: 64.8%, B: 42.9%, p<0.001) were more frequent among patients under 50, and traditional age-linked factors like hypertension (A: 58%, B: 75.7%, p<0.001), diabetes (A: 21.6%, B: 38.6%, p<0.001) were more common in the older group. Acute ST-elevation myocardial infarction was more frequent among the young (A: 55.4%, B: 47.4%, p=0.006), as non-ST clinical presentation was higher among elder patients. Regarding angiographic presentation, single vessel CAD was higher in group A (A: 50.3%, B: 40.9%, p<0.001), while multivessel diasease was higher in group B (A: 33.3%, B: 53.9%, p<0.001). At a mean follow-up of 5 years, older patients had a worst prognosis, registering a higher rate of cardiovascular death (A: 4.1%, B: 8.6%, p=0.002) and higher MACE (A: 26.8%, B: 31%, p=0.128),. Adding the genetic risk score (GRS), we achieved only a slight improvement in the AUC for predicting CAD (0.796->0.805, p=0.0178 and 0.748->0.761, p=0.0007 in patients under and over 50, respectively).
Conclusion
Coronary artery disease is not all the same, as premature CAD shares a unique and specific pattern of risk factors, clinical presentation, angiographic severity and prognosis. Genetics should not be used as an excuse to justify premature CAD, as there is frequently more than one potentially reversible risk factor present even in young patients and the additive predictive value of GRS is modest.

Abstract
Stress, a well-known sculptor of brain plasticity, is shown to suppress hippocampal neurogenesis in the adult brain; yet, the underlying cellular mechanisms are poorly investigated. Previous studies have shown that chronic stress triggers hyperphosphorylation and accumulation of the cytoskeletal protein Tau, a process that may impair the cytoskeleton-regulating role(s) of this protein with impact on neuronal function. Here, we analyzed the role of Tau on stress-driven suppression of neurogenesis in the adult dentate gyrus (DG) using animals lacking Tau (Tau-knockout; Tau-KO) and wild-type (WT) littermates. Unlike WTs, Tau-KO animals exposed to chronic stress did not exhibit reduction in DG proliferating cells, neuroblasts and newborn neurons; however, newborn astrocytes were similarly decreased in both Tau-KO and WT mice. In addition, chronic stress reduced phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR)/glycogen synthase kinase-3β (GSK3β)/β-catenin signaling, known to regulate cell survival and proliferation, in the DG of WT, but not Tau-KO, animals. These data establish Tau as a critical regulator of the cellular cascades underlying stress deficits on hippocampal neurogenesis in the adult brain.

Abstract
BACKGROUND A growing body of evidence suggests that indicators of social disadvantage are associated with an increased risk of psychosis. However, only a few studies have specifically looked at cumulative effects and long-term associations. The aims of this study are: To compare the prevalence of specific indicators of social disadvantage at, and prior to, first contact with psychiatric services in patients suffering their first episode of psychosis and in a control sample. To explore long-term associations, cumulative effects, and direction of effects. METHOD We collected information on social disadvantage from 332 patients and from 301 controls recruited from the local population in South London. Three indicators of social disadvantage in childhood and six indicators of social disadvantage in adulthood were analysed. RESULTS Across all the domains considered, cases were more likely to report social disadvantage than were controls. Compared with controls, cases were approximately two times more likely to have had a parent die and approximately three times more likely to have experienced a long-term separation from one parent before the age of 17 years. Cases were also more likely than controls to report two or more indicators of adult social disadvantage, not only at first contact with psychiatric services [odds ratio (OR) 9.5], but also at onset of psychosis (OR 8.5), 1 year pre-onset (OR 4.5), and 5 years pre-onset (OR 2.9). CONCLUSIONS Greater numbers of indicators of current and long-term exposure are associated with progressively greater odds of psychosis. There is some evidence that social disadvantage tends to cluster and accumulate.

Abstract
MK 3814 is a potent and selective antagonist of the A2a receptor. A2a receptor antagonists have the potential for the treatment of Parkinson disease. Three distinct isotopically labelled forms of MK 3814 were synthesized. [3 H]MK 3814 was prepared for a preliminary absorption, distribution, metabolism, and excretion data (ADME) evaluation of the compound and [14 C]MK 3814 for more definitive ADME work, including an absorption, metabolism, and excretion study in man. In addition, [2 H4 ]MK 3814 was prepared as an internal standard for a liquid chromatography mass spectrometry bioanalytical method. This paper discusses the synthesis of 3 isotopically labelled forms of MK 3814.

Abstract
Recent genetic studies have revealed an association between polymorphisms at the ADAMTS7 gene locus and coronary artery disease (CAD) risk. Functional studies have shown that a CAD-associated polymorphism (rs3825807) affects ADAMTS7 maturation and vascular smooth muscular cell (VSMC) migration. Here, we tested whether ADAMTS7 (A/G) SNP is associated with cardiovascular (CV) survival in patients with established CAD. A cohort of 1,128 patients with angiographic proven CAD, who were followed up prospectively for a mean follow-up period of 63 (range 6–182) mo, were genotyped for rs3825807 A/G. Survival statistics (Cox regression) compared heterozygous (AG) and wild-type (AA) with the reference homozygous GG. Kaplan-Meier (K-M) survival curves were performed according to ADAMTS7 genotypes for CV mortality. Results showed that 47.3% of patients were heterozygous (AG), 36.5% were homozygous for the wild-type allele (AA) and only 16.2% were homozygous for the GG genotype. During the follow-up period, 109 (9.7%) patients died, 77 (6.8%) of CV causes. Survival analysis showed that AA genotype was an independent risk factor for CV mortality compared with reference genotype GG (HR = 2.7, P = 0.025). At the end of follow-up, the estimated survival probability (K-M) was 89.8% for GG genotype, 82.2% for AG and 72.3% for AA genotype ( P = 0.039). Carriage of the mutant G allele of the ADAMTS7 gene was associated with improved CV survival in patients with documented CAD. The native overfunctional ADAMTS7 allele (A) may accelerate VSMC migration and lead to neointimal thickening, atherosclerosis progression and acute plaque events. ADAMTS7 gene should be further explored in CAD for risk prediction, mechanistic and therapeutic goals.

Abstract
Pediococcus pentosaceus SB83 is a bacteriocinogenic culture having potential use as a vaginal probiotic. The objective of this study was to evaluate the behaviour of P. pentosaceus SB83 incorporated in a liquid system for eventually formulating a gel for vaginal delivery. The vaginal probiotic incorporated into glycerol was able to survive in simulated vaginal fluid at normal vaginal pH (4.2) and at pH of vaginal infections (5.5 and 6.5). The probiotic can be stored at 4 °C for a longer period of time than at room temperature, however, after 13 weeks of storage at low temperature, there was a total loss of viable cells. The probiotic strain incorporated into glycerol showed bacteriocinogenic activity in simulated vaginal fluid, although the antimicrobial activity against Listeria monocytogenes declined during storage. This study showed the behaviour of P. pentosaceus SB83 in glycerol and in simulated vaginal fluid. However, it is necessary to optimise the formulation to produce an actively probiotic vaginal gel.

Abstract
AIMS The aim of our research was to select, identify and characterize an isolate of lactic acid bacteria to be considered as a vaginal probiotic. METHODS AND RESULTS Thirty-five isolates of Pediococcus spp. showed bacteriocinogenic activity against Listeria monocytogenes and the ability to survive in simulated vaginal fluid (SVF) at pH 4.2. One isolate of Pediococcus spp. was selected and characterized to evaluate its safety before the use as vaginal probiotic. Pediococcus pentosaceus SB83 did not show the presence of virulence factors such as the production of gelatinase, lipase and DNase, haemolytic activity, nor the presence of virulence genes (genes esp, agg, gelE, efaAfm, efaAfs, cylA, cylB and cylM). Pediococcus pentosaceus SB83 was considered sensitive to chloramphenicol, gentamicin, streptomycin, kanamycin, erythromycin and ampicillin. This strain was considered resistant to tetracycline and vancomycin. Pediococcus pentosaceus SB83 was a biofilm producer at different pH values (4.2, 5.5 and 6.5) in SVF and in de Man, Rogosa and Sharpe medium. CONCLUSIONS The in vitro results provide a basis for the use of P. pentosaceus SB83 as a vaginal probiotic, to prevent colonization by L. monocytogenes in pregnant women. SIGNIFICANCE AND IMPACT OF STUDY The application of vaginal probiotics could have the potential for preventing vaginal infections and consequently reduce abortion and neonatal infections.

Abstract
Abstract
Epigenetic silencing of tumor suppressing genes by promoter-specific DNA methylation is common in many types of cancer. As an early event, this process has been well shown to promote tumor initiation and progression; however little is known how such epigenetic silencing can contribute to tumor metastasis. The PRKD1 gene encodes Protein Kinase D1 (PKD1), a serine/threonine kinase expressed in epithelial cells of the normal mammary gland that maintains the epithelial phenotype of normal breast cells and prevents epithelial-to-mesenchymal transition (EMT). PKD1 is also a critical suppressor of tumor cell invasion and is silenced in expression and activity during breast tumor progression. Here, we show that aberrant methylation of PRKD1 promoter region is not only correlated with the silencing of its expression but is also associated with invasiveness of breast cancer cell lines and with aggressiveness of breast tumors. Using the highly invasive MDA-MB-231 cells, we show that the inhibition of PRKD1 promoter methylation with the DNA methyltransferase inhibitor decitabine restores PKD1 expression and significantly decreases their invasive abilities in vitro. More importantly, in a tumor xenograft model it dramatically blocks tumor spread and metastasis to the lung in a PKD1-dependent fashion. Our data suggest that the status of epigenetic regulation of the PRKD1 promoter can provide valid information on the invasiveness of breast tumors, and therefore could serve as an early diagnostic marker. Moreover, targeted upregulation of PKD1 expression may be used as a therapeutic approach to reverse the invasive phenotype of breast cancer cells.

Abstract
The effects of previous exposure to sub-lethal acidic and osmotic stresses on the survival of Listeria monocytogenes during exposure to gastro-intestinal (GI) tract simulation, was investigated. Six L. monocytogenes strains isolated from cheeses were selected and exposed to high salt concentrations or acidic conditions and their viability compared in quick and slow digestions. The results demonstrated that (i) all isolates were more sensitive to the exposure to acidic than to osmotic sub-lethal conditions (ii) significant differences (p < 0.05) between the two types of digestion were observed; in slow digestion, the log reduction was higher for all the tested isolates (iii) all isolates were inhibited in the presence of bile salts for both types of digestion (iv) differences between quick and slow digestion were not observed (p > 0.05) after exposure to either osmotic or acidic stress (v) a higher cellular inactivation (p < 0.001) was observed during the passage through the GI tract simulation after exposure to osmotic than to acidic stresses and (vi) neither osmotic nor acidic sub-lethal stresses conferred resistance to simulated GI tract conditions.
