We propose a framework for the robust and fully-automatic segmentation of magnetic resonance (MR) brain images called “Multi-Atlas Label Propagation with Expectation–Maximisation based refinement” (MALP-EM). The presented approach is on registration (MAPER), highly performant label fusion (joint fusion) intensity-based refinement using EM. further adapt this to be applicable gross changes in anatomy. account consistent errors by relaxing anatomical priors obtained multi-atlas propagation...

Abstract Background and Aims Acute heart failure (AHF) promotes inflammatory activation, which is associated with worse outcomes. Colchicine has proven effective in other cardiovascular conditions characterized by but never been evaluated the setting of AHF. Methods This multicenter, randomized, double-blind placebo-controlled trial included patients AHF, requiring ≥40 mg intravenous furosemide, regardless their left ventricular ejection fraction (LVEF) inpatient or outpatient setting....

Background: Poor natriuresis has been associated with a poorer response to diuretic treatment and worse prognosis in acute heart failure. Recommendations on how when measure urinary sodium (UNa) are lacking. We aim evaluate UNa quantification after furosemide stress test (FST) capacity predict appropriate decongestion during failure hospitalization. Methods: Patients underwent an FST day-1 of admission, was measured 2 hours after, dividing patients into low or high based the sample median...

Abstract Aims Sacubitril/valsartan is safe when initiated during hospitalization in a clinical trial setting. Its safety real‐life population not stablished. We compared the initiation of sacubitril/valsartan non‐selected population, PIONEER‐HF trial, and outpatients. Methods results Multicentre registry included 527 patients: 100 were started on (19.0%) 427 as outpatients (81.0%). Compared with those pivotal inpatients our cohort older (71 ± 12 vs. 61 14 years; P < 0.001); had more...

Immunotherapy targeting ganglioside antigens is a powerful tool for the treatment of high risk neuroblastoma. However, only with anti-GD2 antibodies has been used in clinical practice and other options may be pursued. We report use racotumomab, an anti-idiotype vaccine against N-glycolyl neuraminic acid (NeuGc)- containing gangliosides, eliciting immune response child relapsed neuroblastoma expressing NeuGcGM3 ganglioside.
