Sepsis-trained macrophages promote antitumoral tissue-resident T cells.

Sepsis induces immune alterations, which last for months after the resolution of illness. The effect of this immunological reprogramming on the risk of developing cancer is unclear. Here we use a national claims database to show that sepsis survivors had a lower cumulative incidence of cancers than matched nonsevere infection survivors.

Incremental value of the combined brain-cardiac CT protocol on prediction of atrial fibrillation after stroke.

Introduction: Atrial fibrillation (AF) is one of the most common causes of ischemic stroke. It is essential to target patients at highest risk of AF detected after stroke (AFDAS), who should benefit from a prolonged rhythm screening strategy. Cardiac-CT angiography (CCTA) was added to the stroke protocol used in our institution in 2018.

Attachment-line, crossflow and Tollmien-Schlichting instabilities on swept ONERA-D and Joukowski airfoils.

Linear stability analyses are performed to investigate the boundary layer instabilities developing in an incompressible flow around the whole leading-edge of swept ONERA-D and Joukowski airfoils of infinite span. The stability analyses conducted in our study are global in the chordwise direction and local in the spanwise direction. A neutral curve is drawn at a given leading-edge Reynolds number and several overlapping regions, called "lobes", are identified on a physical basis.

Coronary-subclavian steal syndrome causing myocardial infarction after arteriovenous fistula creation: a case report.

Coronary subclavian steal syndrome (CSSS) caused by left subclavian artery (LSA) stenosis is a rare cause of myocardial infarction in patients having coronary artery bypass grafting (CABG), and it has also been observed after an arteriovenous fistula (AVF) was made. A 79-year-old woman who had undergone CABG years earlier and an AVF creation 1 month before experienced a non-ST-elevation myocardial infarction (NSTEMI). While selective catheterization of the left internal thoracic artery graft was impossible, a computed tomography scanner showed patency of all bypasses and proximal subocclusive LSA stenosis, and the digital blood pressure measurements objectified a haemodialysis-induced distal ischaemia.
