TL;DR: The results do not support the existence of strong interaction effects as a common risk factor for MI, and a modest upper limit on the magnitude that epistatic risk effects are likely to have at the population level is placed.
Abstract: The genetic loci that have been found by genome-wide association studies to modulate risk of coronary heart disease explain only a fraction of its total variance, and gene-gene interactions have been proposed as a potential source of the remaining heritability. Given the potentially large testing burden, we sought to enrich our search space with real interactions by analyzing variants that may be more likely to interact on the basis of two distinct hypotheses: a biological hypothesis, under which MI risk is modulated by interactions between variants that are known to be relevant for its risk factors; and a statistical hypothesis, under which interacting variants individually show weak marginal association with MI. In a discovery sample of 2,967 cases of early-onset myocardial infarction (MI) and 3,075 controls from the MIGen study, we performed pair-wise SNP interaction testing using a logistic regression framework. Despite having reasonable power to detect interaction effects of plausible magnitudes, we observed no statistically significant evidence of interaction under these hypotheses, and no clear consistency between the top results in our discovery sample and those in a large validation sample of 1,766 cases of coronary heart disease and 2,938 controls from the Wellcome Trust Case-Control Consortium. Our results do not support the existence of strong interaction effects as a common risk factor for MI. Within the scope of the hypotheses we have explored, this study places a modest upper limit on the magnitude that epistatic risk effects are likely to have at the population level (odds ratio for MI risk 1.3-2.0, depending on allele frequency and interaction model).

TL;DR: Panton-Valentine leukocidin expressing S. aureus pneumonia can cause severe, necrotizing pneumonia associated with acute respiratory distress syndrome, which can be particularly challenging to manage, and managed with extracorporeal membrane oxygenation.
Abstract: Objective:Panton-Valentine leukocidin expressing Staphylococcus aureus pneumonia, an infection that affects predominantly young people, has a mortality rate of >70% despite aggressive conventional management. Little information is available on the management of patients with Panton-Valentine leukoci

TL;DR: Cases of the most common abdominal presentations of neurofibroma, malignant peripheral nerve sheath tumor, pheochromocytoma, carcinoid, gastrointestinal stromal tumor, and seminoma are presented.
Abstract: The purpose of this review is to illustrate, with examples, the abdominal manifestations of neurofibromatosis type 1 (NF1) on imaging, with emphasis on computed tomography. Mutations of the NF1 gene lead to abnormal tumor suppression. Consequently, NF1 is a complex disease, with patients having an increased prevalence of benign and malignant neoplasms throughout the body. We present cases of the most common abdominal presentations: neurofibroma, malignant peripheral nerve sheath tumor, pheochromocytoma, carcinoid, gastrointestinal stromal tumor, and seminoma.

24 Feb 2018TL;DR: The ESVS guidelines were the first to recommend that CEA/CAS should be targeted into a smaller cohort of patients who may be ‘higher risk for stroke’ on medical therapy, and there remain concerns that the results obtained in RCTs may not be generalisable into routine clinical practice.
Abstract: The European Society for Vascular Surgery (ESVS) has recently prepared updated guidelines for the management of patients with symptomatic and asymptomatic atherosclerotic carotid artery disease, with specific reference to the roles of best medical therapy, carotid endarterectomy (CEA) and carotid artery stenting (CAS). In symptomatic patients, there is a drive towards performing carotid interventions as soon as possible after onset of symptoms. This is because it is now recognised that the highest risk period for recurrent stroke is the first 7–14 days after onset of symptoms. The guidelines advise that there is a role for both CEA and CAS, but the levels of evidence are slightly lower for CAS than for CEA. This is because 30-day risks of death/stroke in the randomised controlled trials (RCTs) were significantly higher than after CEA (especially in the first 7–14 days after onset of symptoms) and there are concerns that the results obtained in the RCTs may not be generalisable into routine clinical practice. In asymptomatic patients, the 2018 ESVS guidelines were the first to recommend that CEA/CAS should be targeted into a smaller cohort of patients who may be ‘higher risk for stroke’ on medical therapy. As with symptomatic patients, the ESVS guidelines advise that there is a potential role for both CEA and CAS, but the levels of evidence are again slightly lower for CAS than for CEA. This is because 30-day risks of death/stroke in the two largest RCTs, which used credentialed (experienced CAS practitioners), were only just within the accepted 3% risk threshold and there remain concerns that the results obtained in RCTs may not be generalisable into routine clinical practice.

TL;DR: The role of mitral regurgitation in the BIOlogy Study to TAilored Treatment in chronic heart failure (BIOSTAT-CHF) was investigated in this paper.
Abstract: Background Few data regarding the prevalence and prognostic impact of mitral regurgitation (MR) in patients with worsening chronic or new-onset acute heart failure (HF) are available. We investigated the role of MR in the BIOlogy Study to TAilored Treatment in Chronic Heart Failure (BIOSTAT-CHF). Methods and results We performed a retrospective post-hoc analysis including patients from both the index and validation BIOSTAT-CHF cohorts with data regarding MR status. The primary endpoint was a composite of all-cause death or HF hospitalization. Among 4023 patients included, 1653 patients (41.1%) had moderate-severe MR. Compared to others, patients with moderate-severe MR were more likely to have atrial fibrillation and chronic kidney disease and had larger left ventricular (LV) dimensions, lower left ventricular ejection fraction (LVEF), worse QoL, and higher plasma concentrations of NT-proBNP. A primary outcome event occurred in 697 patients with, compared to 836 patients without, moderate-severe MR (Kaplan-Meier 2-year estimate: 42.2% vs. 35.3%; hazard ratio [HR], 1.28; 95% confidence interval [CI], 1.16-1.41; log-rank p Conclusions Moderate-severe MR is common in patients with worsening chronic or new-onset acute HF and is strongly associated with outcome, independently of other features related to HF severity.
