Two new species, Russula pseudopunicea C.L.Hou, G.Q.Cheng & H.Zhou sp. nov. and R. wulingshanensis C.L.Hou, G.Q.Cheng & H.Zhou sp. nov., from Yanshan mountains in North China are described herein based on morphological and phylogenetic analyses of nrITS, and nrLSU-rpb2-mtSSU gene regions. Morphologically, R. pseudopunicea sp. nov. is characterised by a reddish brown, light brown to brownish orange pileus with a greyish yellow margin, subglobose to broadly ellipsoid basidiospores with warts forming a partial reticulum and pleurocystidia turning grey to purplish red in sulfovanillin. Russula wulingshanensis sp. nov. is characterised by a purple pinkish pileus with a grey-white to grey-purple margin, subglobose to broadly ellipsoid basidiospores with isolated warts, and pileocystidia turning black in sulfovanillin. Phylogenetic and morphological analyses resolved the two species in Russula subg. Heterophyllidia. Russula pseudopunicea sp. nov. and R. wulingshanensis sp. nov. were placed in the lineages of subsect. Virescentinae and subsect. Griseinae, respectively.
Recent studies have reported that takotsubo syndrome (TTS) patients are suffering from life-threatening arrhythmias. The aim of our study was to understand the short and long-term usefulness of cardiac implantable electronic devices in TTS patients.We constituted a collective of 142 patients in a bi-centric study diagnosed with TTS between 2003 and 2017. The patient groups, divided according to the treatment with (n = 9, 6.3%) or without cardiac devices (n = 133, 93.7%), were followed-up to determine the importance of devices and its complications. One patient was treated with a permanent pacemaker, five patients with a wearable cardioverter defibrillator, two patients with a subcutaneous defibrillator and one patient with a transvenous defibrillator. Regular device check-up was documented in all patients, presenting an ongoing high-degree AV-block. Neither device complications nor life-threatening tachyarrhythmias were documented after acute TTS event. However, patients comprising the device group suffered significantly more often from a highly reduced EF (30 ± 7.7% versus 39.1 ± 9.7%; p < 0.05), cardiogenic shock with use of inotropic agents (66.6% versus 16.6%; p < 0.05) and cardiopulmonary resuscitation (44.4% versus 5.3%; p < 0.05). Our data confirm the usefulness of pacemaker in TTS patients. However, the cardioverter defibrillator including wearable cardioverter defibrillator may not be recommended.
