Influenza Vaccination for the Prevention of Cardiovascular Disease in the Americas: Consensus document of the Inter-American Society of Cardiology and the Word Heart Federation

Background Cardiovascular mortality is decreasing but remains the leading cause of death world-wide. Respiratory infections such as influenza significantly contribute to morbidity and mortality in patients with cardiovascular disease. Despite of proven benefits, influenza vaccination is not fully implemented, especially in Latin America. Objective The aim was to develop a regional consensus with recommendations regarding influenza vaccination and cardiovascular disease. Methods A multidisciplinary team composed by experts in the management and prevention of cardiovascular disease from the Americas, convened by the Inter-American Society of Cardiology (IASC) and the World Heart Federation (WHF), participated in the process and the formulation of statements. The modified RAND/UCLA methodology was used. This document was supported by a grant from the WHF. Results An extensive literature search was divided into seven questions, and a total of 23 conclusions and 29 recommendations were achieved. There was no disagreement among experts in the conclusions or recommendations. Conclusions There is a strong correlation between influenza and cardiovascular events. Influenza vaccination is not only safe and a proven strategy to reduce cardiovascular events, but it is also cost saving. We found several barriers for its global implementation and potential strategies to overcome them

Populations of planets in multiple star systems

Astronomers have discovered that both planets and binaries are abundant throughout the Galaxy. In combination, we know of over 100 planets in binary and higher-order multi-star systems, in both circumbinary and circumstellar configurations. In this chapter we review these findings and some of their implications for the formation of both stars and planets. Most of the planets found have been circumstellar, where there is seemingly a ruinous influence of the second star if sufficiently close (<50 AU). Hosts of hot Jupiters have been a particularly popular target for binary star studies, showing an enhanced rate of stellar multiplicity for moderately wide binaries (>100 AU). This was thought to be a sign of Kozai-Lidov migration, however recent studies have shown this mechanism to be too inefficient to account for the majority of hot Jupiters. A couple of dozen circumbinary planets have been proposed around both main sequence and evolved binaries. Around main sequence binaries there are preliminary indications that the frequency of gas giants is as high as those around single stars. There is however a conspicuous absence of circumbinary planets around the tightest main sequence binaries with periods of just a few days, suggesting a unique, more disruptive formation history of such close stellar pairs.Comment: Invited review chapter, accepted for publication in "Handbook of Exoplanets", ed.

Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer.

To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC. This identified three additional susceptibility loci at 2q13, 8q24.1 and 12q24.31. Integrated analyses of genes and regulatory biofeatures at each locus predicted candidate susceptibility genes, including OBFC1, a new candidate susceptibility gene for low-grade and borderline serous EOC

Hybrid Processing

Human societies have converted biomass into energy and products for millennia using both biochemical and thermochemical processes. Familiar examples of biochemical processing includes fermentation of sugar- or starch-rich crops and milk into sauerkraut, beer, wine, yogurt, and cheese. Familiar examples of thermochemical processing include baking and cooking of food and burning wood for heat and power

Polygenic Risk Modelling for Prediction of Epithelial Ovarian Cancer Risk

Funder: Funding details are provided in the Supplementary MaterialAbstractPolygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance over standard approaches of PRS construction. Here, we implemented computationally-efficient, penalized, logistic regression models (lasso, elastic net, stepwise) to individual level genotype data and a Bayesian framework with continuous shrinkage, “select and shrink for summary statistics” (S4), to summary level data for epithelial non-mucinous ovarian cancer risk prediction. We developed the models in a dataset consisting of 23,564 non-mucinous EOC cases and 40,138 controls participating in the Ovarian Cancer Association Consortium (OCAC) and validated the best models in three populations of different ancestries: prospective data from 198,101 women of European ancestry; 7,669 women of East Asian ancestry; 1,072 women of African ancestry, and in 18,915 BRCA1 and 12,337 BRCA2 pathogenic variant carriers of European ancestry. In the external validation data, the model with the strongest association for non-mucinous EOC risk derived from the OCAC model development data was the S4 model (27,240 SNPs) with odds ratios (OR) of 1.38(95%CI:1.28–1.48,AUC:0.588) per unit standard deviation, in women of European ancestry; 1.14(95%CI:1.08–1.19,AUC:0.538) in women of East Asian ancestry; 1.38(95%CI:1.21-1.58,AUC:0.593) in women of African ancestry; hazard ratios of 1.37(95%CI:1.30–1.44,AUC:0.592) in BRCA1 pathogenic variant carriers and 1.51(95%CI:1.36-1.67,AUC:0.624) in BRCA2 pathogenic variant carriers. Incorporation of the S4 PRS in risk prediction models for ovarian cancer may have clinical utility in ovarian cancer prevention programs.</jats:p

Background: In patients with coronary artery disease (CAD), the presence of atherosclerotic lesions in other vascular beds is associated with a markedly worse prognosis. Aim: To determine the prevalence and predictors of extracranial supra-aortic artery atherosclerotic disease (SAD) in patients with suspected CAD. Methods: Supra-aortic artery angiography was performed in 379 consecutive patients aged 64.2 &#177; 8.8 years (231 male) referred for coronary angiography. Clinical and laboratory data (total cholesterol, LDL, HDL cholesterol, hs-CRP, creatinine level) and left ventricular ejection fraction were analysed. Results: Significant stenosis (ł 50% by quantitative angiography) within at least one main branch of the coronary arteries was found in 314 (82.8%) patients, including 87 (27.7%), 96 (30.6%) and 131 (41.7%) with 1-vessel, 2-vessel, and 3-vessel CAD, respectively. Among all 379 patients, stenosis ł 50% of the carotid artery was documented in 9.5%, vertebral in 13.7%, and subclavian in 7.4% of patients. We found 130 stenoses ł 50% within the supra-aortic arteries in 90 patients (23.7% of the whole study group, and 28.7% of CAD patients), including 42 internal carotid artery stenoses in 36 patients, 58 vertebral artery stenoses in 52, and 30 subclavian stenoses in 28 patients. In 24 (6.3%) patients more than one SAD was present. The SAD ł 50% was found in 8 (12.3%) patients without significant CAD, in 22 (25.3%), 17 (17.7%) and 43 (32.8%) with 1-, 2- and 3-vessel CAD, respectively (p = 0.001). Independent predictors of SAD ł 50% identified by multivariate analysis were: previous neurological ischaemic event (p = 0.001), CAD (p = 0.015), creatinine level (p = 0.031), male gender (p = 0.001), claudication (p < 0.001) and low HDL cholesterol (p = 0.033). The following independent predictors of vertebral and/or subclavian artery stenosis ł 50% were identified: CAD severity (p = 0.002), creatinine level (p = 0.024), male gender (p = 0.013), claudication (p < 0.001) and low HDL cholesterol level (p = 0.059). Conclusions: In a large patient sample, we have found that significant supra-aortic atherosclerosis is present in a quater of patients with suspected CAD. Importantly, SAD prevalence increases with CAD severity. Previous neurological ischaemic event, CAD, creatinine level, male gender, claudication and hyperlipidaemia were identified as independent predictors of SAD ł 50%.Wstęp: U osób z chorobą wieńcową (CAD) miażdżyca tętnic pozawieńcowych związana jest ze złym rokowaniem. Cel: Ocena częstości występowania zwężeń tętnic dogłowowych (SAS) i ich czynniki predykcyjne u chorych z CAD. Metody: Angiografię tętnic dogłowowych wykonano u 379 kolejnych chorych (231 mężczyzn) w średnim wieku 64,2 &#177; 8,8 roku, poddanych angiografii tętnic wieńcowych. U wszystkich chorych poddano analizie obraz kliniczny, badania laboratoryjne: stężenie cholesterolu całkowitego, frakcji LDL i HDL, hs-CRP, kreatyniny, oraz oceniono frakcję wyrzutową lewej komory. Wyniki: Zwężenia ł 50% w co najmniej jednej głównej gałęzi tętnicy wieńcowej stwierdzono u 314 (82,8%) chorych, w tym u 87 (27,7%) 1-naczyniową CAD, u 96 (30,6%) chorych 2-naczyniową oraz u 131 (41,7%) &#8211; 3-naczyniową CAD. Brak zwężeń lub zwężenia < 50% w tętnicach wieńcowych odnotowano u 65 (17,2%) osób. Stwierdzono 130 zwężeń ł 50% w tętnicach dogłowowych u 90 chorych, co stanowi 23,7% całej grupy oraz 28,7% wśród chorych z CAD. Stwierdzono 42 zwężenia w tętnicy szyjnej wewnętrznej u 36 chorych, 58 zwężeń tętnicy kręgowej u 52 oraz 30 zwężeń tętnicy podobojczykowej u 28 chorych. Zwężenie więcej niż jednej tętnicy dogłowowej było obecne u 24 (6,3%) chorych. Zwężenia tętnic dogłowowych ł 50% stwierdzono u 8 (12,3%) chorych bez istotnych zwężeń w tętnicach wieńcowych oraz u odpowiednio 22 (25,3%), 17 (17,7%) i 43 (32,8%) chorych z 1-, 2- i 3-naczyniową chorobą wieńcową (p = 0,001). Metodą analizy wieloczynnikowej wykazano, że niezależnymi czynnikami prognostycznymi SAS ł 50% są: przebyty udar niedokrwienny mózgu (p < 0,001), CAD (p = 0,015), stężenie kreatyniny (p = 0,031), płeć męska (p = 0,001), chromanie kończyn dolnych (p < 0,001) oraz niskie stężenie frakcji HDL cholesterolu (p = 0,033). Wnioski: Zwężenie tętnic dogłowowych jest częstym znaleziskiem u chorych kierowanych na koronarografię z podejrzeniem oraz udokumentowaną CAD i dotyczy ok. 1/4 chorych. Częstość SAS wzrasta wraz ze wzrostem zaawansowania choroby wieńcowej. Zidentyfikowano następujące niezależne czynniki prognostyczne SAS ł 50%: przebyty udar niedokrwienny mózgu, CAD, stężenie kreatyniny, płeć męska, chromanie kończyn dolnych oraz niskie stężenie frakcji HDL cholesterolu
