Cor Triatriatum Dexter: Contrast Echocardiography Is Key to the Diagnosis of a Rare but Treatable Cause of Neonatal Persistent Cyanosis

Cor triatriatum dexter (CTD) is an extremely uncommon and underreported congenital cardiac anomaly in which the persistence of the embryonic right venous valve separates the right atrium into two chambers with varying degrees of obstruction to antegrade flow and variable degree of right to left shunt at atrial level. Depending on the size of the valves, clinical manifestations vary from absence of symptoms to severe hypoxia, requiring urgent surgical correction. We herein describe the diagnostic difficulties in a case of neonatal CTD, who developed increasingly severe and unresponsive cyanosis, first interpreted as postnatal maladjustment with pulmonary hypertension. The failure to respond to oxygen and pulmonary vasodilators led us to reconsider a different diagnosis. The use of contrast echocardiography improved the diagnostic performance of transthoracic echocardiogram (TTE) and revealed a massive right-to-left shunt secondary to the presence of an atrial membrane that required urgent surgery

Ideje a praxe zelených ploch v evropských městech

Již téměř dvě století jsou zelené plochy v evropských městech přehodnocovány a tvořeny na základě měnících se idejí a praktických postupů týkajících se významu přírody ve městech. I když jsou v dnešních evropských městech velké rozdíly v kvantitě a kvalitě zelených ploch, myšlenky a postupy, které stojí za jejich tvorbou nebo zánikem, jsou na celém kontinentu vcelku podobné. Od poloviny devatenáctého století začali představitelé evropských měst vnášet přírodu zpět do města, aby čelili negativním dopadům industrializace. Později začali modernističtí architekti a projektanti používat vědecké metody a populistické ideje přírody ve snaze vytvořit dostupné zdravé bydlení pro rychle se rozvíjející městskou průmyslovou pracovní sílu. Nejnověji evropská města přijímají jako hlavní ideu udržitelnost, což je někdy protichůdné úsilí o rovnováhu mezi neoliberální komodifikací přírody a vědecky legitimními přínosy pro kvalitu života.For almost two centuries, green spaces in European cities have been rethought and built based on the shifting ideas and practices about the role of nature in cities. Although there is a great diversity in the quantity and quality of green spaces in European cities today, the ideas and practices behind their creation and destruction are quite common across the continent. Starting in the mid-nineteenth century, European city leaders started bringing nature back into the city to counter the negative effects of industrialization. Later, modernist architects and planners began using cientific methods and populist ideas of nature in an attempt to create accessible healthy quality living for a rapidly expanding urban industrial workforce. Most recently, European cities are embracing sustainability, a sometimes contradictory effort to balance neoliberal commodification of nature with its scientifically legitimated quality of life benefits

The ATLAS experiment at the CERN Large Hadron Collider: a description of the detector configuration for Run 3

Abstract The ATLAS detector is installed in its experimental cavern at Point 1 of the CERN Large Hadron Collider. During Run 2 of the LHC, a luminosity of  ℒ = 2 × 1034 cm-2 s-1 was routinely achieved at the start of fills, twice the design luminosity. For Run 3, accelerator improvements, notably luminosity levelling, allow sustained running at an instantaneous luminosity of  ℒ = 2 × 1034 cm-2 s-1, with an average of up to 60 interactions per bunch crossing. The ATLAS detector has been upgraded to recover Run 1 single-lepton trigger thresholds while operating comfortably under Run 3 sustained pileup conditions. A fourth pixel layer 3.3 cm from the beam axis was added before Run 2 to improve vertex reconstruction and b-tagging performance. New Liquid Argon Calorimeter digital trigger electronics, with corresponding upgrades to the Trigger and Data Acquisition system, take advantage of a factor of 10 finer granularity to improve triggering on electrons, photons, taus, and hadronic signatures through increased pileup rejection. The inner muon endcap wheels were replaced by New Small Wheels with Micromegas and small-strip Thin Gap Chamber detectors, providing both precision tracking and Level-1 Muon trigger functionality. Trigger coverage of the inner barrel muon layer near one endcap region was augmented with modules integrating new thin-gap resistive plate chambers and smaller-diameter drift-tube chambers. Tile Calorimeter scintillation counters were added to improve electron energy resolution and background rejection. Upgrades to Minimum Bias Trigger Scintillators and Forward Detectors improve luminosity monitoring and enable total proton-proton cross section, diffractive physics, and heavy ion measurements. These upgrades are all compatible with operation in the much harsher environment anticipated after the High-Luminosity upgrade of the LHC and are the first steps towards preparing ATLAS for the High-Luminosity upgrade of the LHC. This paper describes the Run 3 configuration of the ATLAS detector.</jats:p
