TL;DR: Among patients undergoing TAVR, younger age, male sex, history of diabetes mellitus, and moderate to severe residual aortic regurgitation were significantly associated with an increased risk of infective endocarditis.
Abstract: Importance Limited data exist on clinical characteristics and outcomes of patients who had infective endocarditis after undergoing transcatheter aortic valve replacement (TAVR). Objective To determine the associated factors, clinical characteristics, and outcomes of patients who had infective endocarditis after TAVR. Design, Setting, and Participants The Infectious Endocarditis after TAVR International Registry included patients with definite infective endocarditis after TAVR from 47 centers from Europe, North America, and South America between June 2005 and October 2015. Exposure Transcatheter aortic valve replacement for incidence of infective endocarditis and infective endocarditis for in-hospital mortality. Main Outcomes and Measures Infective endocarditis and in-hospital mortality after infective endocarditis. Results A total of 250 cases of infective endocarditis occurred in 20 006 patients after TAVR (incidence, 1.1% per person-year; 95% CI, 1.1%-1.4%; median age, 80 years; 64% men). Median time from TAVR to infective endocarditis was 5.3 months (interquartile range [IQR], 1.5-13.4 months). The characteristics associated with higher risk of progressing to infective endocarditis after TAVR was younger age (78.9 years vs 81.8 years; hazard ratio [HR], 0.97 per year; 95% CI, 0.94-0.99), male sex (62.0% vs 49.7%; HR, 1.69; 95% CI, 1.13-2.52), diabetes mellitus (41.7% vs 30.0%; HR, 1.52; 95% CI, 1.02-2.29), and moderate to severe aortic regurgitation (22.4% vs 14.7%; HR, 2.05; 95% CI, 1.28-3.28). Health care–associated infective endocarditis was present in 52.8% (95% CI, 46.6%-59.0%) of patients. Enterococci species and Staphylococcus aureus were the most frequently isolated microorganisms (24.6%; 95% CI, 19.1%-30.1% and 23.3%; 95% CI, 17.9%-28.7%, respectively). The in-hospital mortality rate was 36% (95% CI, 30.0%-41.9%; 90 deaths; 160 survivors), and surgery was performed in 14.8% (95% CI, 10.4%-19.2%) of patients during the infective endocarditis episode. In-hospital mortality was associated with a higher logistic EuroSCORE (23.1% vs 18.6%; odds ratio [OR], 1.03 per 1% increase; 95% CI, 1.00-1.05), heart failure (59.3% vs 23.7%; OR, 3.36; 95% CI, 1.74-6.45), and acute kidney injury (67.4% vs 31.6%; OR, 2.70; 95% CI, 1.42-5.11). The 2-year mortality rate was 66.7% (95% CI, 59.0%-74.2%; 132 deaths; 115 survivors). Conclusions and Relevance Among patients undergoing TAVR, younger age, male sex, history of diabetes mellitus, and moderate to severe residual aortic regurgitation were significantly associated with an increased risk of infective endocarditis. Patients who developed endocarditis had high rates of in-hospital mortality and 2-year mortality.

TL;DR: The peptide nucleic acid-mediated 5´ nuclease real-time polymerase chain reaction (TaqMan) assay used in this study can be used to efficiently assess EGFR mutations in cfDNA and may be a novel surrogate prognostic marker.
Abstract: Importance The EURTAC trial demonstrated the greater efficacy of erlotinib compared with chemotherapy for the first-line treatment of European patients with advanced non–small-cell lung cancer (NSCLC) harboring oncogenic epidermal growth factor receptor ( EGFR ) mutations (exon 19 deletion or L858R mutation in exon 21) in tumor tissue. Objective To assess the feasibility of using circulating free DNA (cfDNA) from blood samples as a surrogate for tumor biopsy for determining EGFR mutation status and to correlate EGFR mutations in cfDNA with outcome. Design, Setting, and Participants This prespecified analysis was a secondary objective of the EURTAC trial using patients included in the EURTAC trial from 2007 to 2011 with available baseline serum or plasma samples. Patients had advanced NSCLC, oncogenic EGFR mutations in the tumor, and no prior chemotherapy for metastatic disease and were treated with erlotinib or chemotherapy. EGFR mutations were examined in cfDNA isolated from 97 baseline blood samples by our novel peptide nucleic acid–mediated 5´ nuclease real-time polymerase chain reaction (TaqMan) assay. Main Outcomes and Measures Overall survival (OS), progression-free survival (PFS), and response to therapy were correlated with type of EGFR mutations in cfDNA. Results In samples from 76 of 97 (78%) patients with usable blood samples, EGFR mutations in cfDNA were detected. Median OS was shorter in patients with the L858R mutation in cfDNA than in those with the exon 19 deletion (13.7 [95% CI, 7.1-17.7] vs 30.0 [95% CI, 19.3-37.7] months; P EGFR mutations in cfDNA identified the L858R mutation in tumor tissue or in cfDNA as a marker of shorter OS (hazard ratio [HR], 2.70 [95% CI, 1.60-4.56]; P P = .008). For patients with the L858R mutation in tissue, median OS was 13.7 (95% CI, 7.1-17.7) months for patients with the L858R mutation in cfDNA and 27.7 (95% CI, 16.1-46.2) months for those in whom the mutation was not detected in cfDNA (HR, 2.22 [95% CI, 1.09-4.52]; P = .03). In the multivariate analysis of the 76 patients with EGFR mutations in cfDNA, only erlotinib treatment remained an independent predictor of longer PFS (HR, 0.41 [95% CI, 0.23-0.74]; P = .003). Conclusions and Relevance The peptide nucleic acid–mediated 5´ nuclease real-time polymerase chain reaction (TaqMan) assay used in this study can be used to efficiently assess EGFR mutations in cfDNA. The L858R mutation in cfDNA may be a novel surrogate prognostic marker. Trial Registration clinicaltrials.gov Identifier:NCT00446225

TL;DR: New guidelines for the management of acute mesenteric ischaemia are presented to provide recommendations for practice that will lead to improved outcomes for patients.
Abstract: Acute mesenteric ischaemia (AMI) accounts for about 1:1000 acute hospital admissions. Untreated, AMI will cause mesenteric infarction, intestinal necrosis, an overwhelming inflammatory response and death. Early intervention can halt and reverse this process leading to a full recovery, but the diagnosis of AMI is difficult and failure to recognize AMI before intestinal necrosis has developed is responsible for the high mortality of the disease. Early diagnosis and prompt treatment are the goals of modern therapy, but there are no randomized controlled trials to guide treatment and the published literature contains a high ratio of reviews to original data. Much of that data comes from case reports and often small, retrospective series with no clearly defined treatment criteria. A study group of the European Society for Trauma and Emergency Surgery (ESTES) was formed in 2013 with the aim of developing guidelines for the management of AMI. A comprehensive literature search was performed using the Medical Subject Heading (MeSH) thesaurus keywords “mesenteric ischaemia”, “bowel ischaemia” and “bowel infarction”. The bibliographies of relevant articles were screened for additional publications. After an initial systematic review of the literature by the whole group, a steering group formulated questions using a modified Delphi process. The evidence was then reviewed to answer these questions, and recommendations formulated and agreed by the whole group. The resultant recommendations are presented in this paper. The aim of these guidelines is to provide recommendations for practice that will lead to improved outcomes for patients.
