In contrast, oesophageal lesions were observed in no patient ablated with PFA (0%, P &lt; 0.001 vs. thermal methods), despite similar rates of direct contact between the oesophagus and the ablation sites (P = 0.41). Acute lesions were detected on CMR on the descending aorta in 10/23 (43%) after thermal ablation, and in 6/18 (33%) after PFA (P = 0.52). CMR at 3 months showed a complete resolution of oesophageal and aortic LGE in all patients. No patient showed clinical complications.<br /><br /> PFA does not induce any signs of oesophageal injury on CMR after PVI. Due to its tissue selectivity, PFA may improve safety for catheter ablation of AF.<br /><br />PFA does not induce any signs of oesophageal injury on CMR after PVI.

For patients with diabetes mellitus, without a prior history of myocardial infarction or atherosclerotic disease, SGLT2i have been shown to reduce incident heart failure and worsening renal function. SGLT2i therapy is increasing among patients presenting for cardiac surgery. However, the perioperative use of SGLT2i carries a significant risk of euglycaemic diabetic ketoacidosis, due to their catabolic mechanism of action. This case report demonstrates euglycaemic ketoacidosis post-coronary artery bypass grafting secondary to SGLT2i, highlighting the multiple risk factors and consequences of this iatrogenic complication.<br /><br /> Inter-residue distance prediction by deep ResNet (convolutional residual neural network) has greatly advanced protein structure prediction. Currently the most successful structure prediction methods predict distance by discretizing it into dozens of bins. Here we study how well real-valued distance can be predicted and how useful it is for 3D structure modeling by comparing it with discrete-valued prediction based upon the same deep ResNet.<br /><br /> Different from the recent methods that predict only a single real value for the distance of an atom pair, we predict both the mean and standard deviation of a distance and then fold a protein by the predicted mean and deviation. Our findings include 1) tested on the CASP13 FM (free-modeling) targets, our real-valued distance prediction obtains 81% precision on top L/5 long-range contact prediction, much better than the best CASP13 results (70%); 2) our real-valued prediction can predict correct folds for the same number of CASP13 FM targets as the best CASP13 group, despite generating only 20 decoys for each target; 3) our method greatly outperforms a very new real-valued prediction method DeepDist in both contact prediction and 3D structure modeling; and 4) when the same deep ResNet is used, our real-valued distance prediction has 1-6% higher contact and distance accuracy than our own discrete-valued prediction, but less accurate 3D structure models.<br /><br /> https//github.com/j3xugit/RaptorX-3DModeling.<br /><br /> Supplementary data are available at Bioinformatics online.<br /><br />Supplementary data are available at Bioinformatics online.<br /><br /> IntAct App is a Cytoscape 3 application that grants in-depth access to IntAct's molecular interaction data. It builds networks where nodes are interacting molecules (mainly proteins, but also genes, RNA, chemicals…) and edges represent evidence of interaction. Users can query a network by providing its molecules, identified by different fields, and optionally include all their interacting partners in the resulting network. The app offers three visualisations one only displaying interactions, another representing every evidence, and the last one emphasizing evidence where mutated versions of proteins were used. Users can also filter networks and click on nodes and edges to access all their related details. Finally, the application supports automation of its main features via Cytoscape commands.<br /><br /> Implementation available at https//apps.cytoscape.org/apps/intactapp, while the source code is available at https//github.com/EBI-IntAct/IntactApp.<br /><br /> Supplementary data is available at Bioinformatics online.<br /><br />Supplementary data is available at Bioinformatics online.We present the results of a phase 2 study evaluating the combination of obinutuzumab + idelalisib in relapsed/refractory (R/R) Waldenström macroglobulinemia (WM). The goal was to determine the safety and efficacy of a fixed-duration chemotherapy-free treatment. During the induction phase, patients received idelalisib + obinutuzumab for 6 cycles, followed by a maintenance phase with idelalisib alone for ≤2 years. Forty-eight patients with R/R WM were treated with the induction combination, and 27 patients participated in the maintenance phase. The best responses, reached after a median of 6.5 months (interquartile range, 3.4-7.1; range, 2.6-22.1 months), were very good partial response in 5 patients, partial response in 27 patients, and minor response in 3 patients, leading to overall response rate and major response rate estimates of 71.4% (95% confidence interval [CI], 56.7-83.4) and 65.3% (95% CI, 50.4-78.3), respectively. With a median follow-up of 25.9 months, median progression-free survival was 25.4 months (95% CI, 15.7-29.0). Univariate analysis focusing on molecular screening found no significant impact of CXCR4 genotypes on responses and survivals but a deleterious impact of TP53 mutations on survival. Although there was no grade 5 toxicity, 26 patients were removed from the study because of side effects; the most frequent were neutropenia (9.4%), diarrhea (8.6%), and liver toxicity (9.3%). The combination of idelalisib + obinutuzumab is effective in R/R WM. Nonetheless, the apparent lack of impact of genotype on outcome could give new meaning to targeting of the phosphatidylinositol 3-kinase pathway in WM. This trial was registered at www.clinicaltrials.gov as #NCT02962401.The dilemma of whether to treat elderly patients with diffuse large B-cell lymphoma (DLBCL) with a full or reduced dose intensity (DI) of R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone+rituximab) is often faced by clinicians. We conducted a systematic review assessing the impact of R-CHOP DI on DLBCL survival outcomes, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols (PRISMA-P) guidelines. We searched MEDLINE, EMBASE, and Cochrane CENTRAL for studies with ≥100 patients treated with R-CHOP/R-CHOP-like therapies published from January 2002 through November 2020. [https://www.selleckchem.com/btk.html BTK inhibitor research buy] Studies were included if they reported the impact of R-CHOP DI on survival outcomes. We screened records, extracted data, and reviewed all the studies for quality and statistical appraisal. Of 380 screened records, 13 studies including 5188 patients were reviewed. DI was often calculated as the ratio of the cumulative delivered dose of prespecified drug(s) to the cumulative planned dose multiplied by a time-correction factor.
