Fungal systematics and evolution : FUSE 6

Fungal Systematics and Evolution (FUSE) is one of the journal series to address the “fusion” between morphological data and molecular phylogenetic data and to describe new fungal taxa and interesting observations. This paper is the 6th contribution in the FUSE series—presenting one new genus, twelve new species, twelve new country records, and three new combinations. The new genus is: Pseudozeugandromyces (Laboulbeniomycetes, Laboulbeniales). The new species are: Albatrellopsis flettioides from Pakistan, Aureoboletus garciae from Mexico, Entomophila canadense from Canada, E. frigidum from Sweden, E. porphyroleucum from Vietnam, Erythrophylloporus flammans from Vietnam, Marasmiellus boreoorientalis from Kamchatka Peninsula in the Russian Far East, Marasmiellus longistipes from Pakistan, Pseudozeugandromyces tachypori on Tachyporus pusillus (Coleoptera, Staphylinidae) from Belgium, Robillarda sohagensis from Egypt, Trechispora hondurensis from Honduras, and Tricholoma kenanii from Turkey. The new records are: Arthrorhynchus eucampsipodae on Eucampsipoda africanum (Diptera, Nycteribiidae) from Rwanda and South Africa, and on Nycteribia vexata (Diptera, Nycteribiidae) from Bulgaria; A. nycteribiae on Eucampsipoda africanum from South Africa, on Penicillidia conspicua (Diptera, Nycteribiidae) from Bulgaria (the first undoubtful country record), and on Penicillidia pachymela from Tanzania; Calvatia lilacina from Pakistan; Entoloma shangdongense from Pakistan; Erysiphe quercicola on Ziziphus jujuba (Rosales, Rhamnaceae) and E. urticae on Urtica dioica (Rosales, Urticaceae) from Pakistan; Fanniomyces ceratophorus on Fannia canicularis (Diptera, Faniidae) from the Netherlands; Marasmiellus biformis and M. subnuda from Pakistan; Morchella anatolica from Turkey; Ophiocordyceps ditmarii on Vespula vulgaris (Hymenoptera, Vespidae) from Austria; and Parvacoccum pini on Pinus cembra (Pinales, Pinaceae) from Austria. The new combinations are: Appendiculina gregaria, A. scaptomyzae, and Marasmiellus rodhallii. Analysis of an LSU dataset of Arthrorhynchus including isolates of A. eucampsipodae from Eucampsipoda africanum and Nycteribia spp. hosts, revealed that this taxon is a complex of multiple species segregated by host genus. Analysis of an SSU–LSU dataset of Laboulbeniomycetes sequences revealed support for the recognition of four monophyletic genera within Stigmatomyces sensu lato: Appendiculina, Fanniomyces, Gloeandromyces, and Stigmatomyces sensu stricto. Finally, phylogenetic analyses of Rhytismataceae based on ITS–LSU ribosomal DNA resulted in a close relationship of Parvacoccum pini with Coccomyces strobi.http://www.sydowia.at/index.htmpm2021Medical Virolog

Asymptotic behaviour and boundedness of solutions for third-order stochastic differential equation with multi-delay

Abstract In the present paper, we study stochastic stability and stochastic boundedness for the stochastic differential equation (SDE) with multi-delay of third order. The derived results extend and improve some earlier results in the relevant literature, which are related to the qualitative properties of solutions to third-order delay differential equations (DDEs) and SDEs with multi-delay. Two examples are given to illustrate the results

960 Maximizing success in single-session edge - predictive factors of stent migration

Background: Roux-en-Y gastric bypass anatomy poses a challenge in performing ERCP due to the inability to access the excluded stomach and duodenum. EUS-directed gastro-gastric ERCP (EDGE) uses a lumen apposing metal stent (LAMS) to access the excluded stomach and is most often performed in two-stages with initial placement of the LAMS followed by ERCP weeks later. The need for urgent ERCP in this patient population has led to the advent of single-session EDGE with LAMS and ERCP on the same day. The most serious and common complication of this procedure is intra-procedural migration of the LAMS. The purpose of this study was to identify predictive factors of LAMS complications during single-session EDGE in a large multicenter cohort. Methods: A multi-centered, retrospective chart review was conducted at nine tertiary medical centers. Single-session EDGE procedures were identified and data including age, gender, LAMS diameter, dilation, route of LAMS placement (gastric or jejunal), stent fixation and procedure complications were collected. The primary outcome was intra-procedural LAMS migration. Groups were compared using Fisher’s exact test for univariate analysis and binary logistic regression analysis to predict independent factors associated with stent migration. Results: 131 patients were included in the study who underwent single-session EDGE. Median age=58 y, 74.8% were female. LAMS migration occurred in 12 patients (9.1%). In univariate analysis, statistically fewer LAMS migrations occurred in patients with a 20mm diameter LAMS (2/84) vs 15mm (7/42), p=0.006, those with suture fixation, p=0.032, and those who underwent LAMS dilation, p=0.026. Location of LAMS placement did not affect the rate of stent migration (2/40 jejunal vs 10/91 gastric, p=0.343) although a trend towards more migration in the trans-gastric route was observed. The use of electrocautery-enhanced stents did not influence the rate of migration. Double pigtail stents for anchoring did not reduce the rate of migration. Binary logistic regression analysis of stent diameter, dilation, suture fixation, access route and electrocautery identified that 15mm stents were significantly more likely to migrate than 20mm (OR=7.9; 95% CI:1.3-47; p=0.024). Of the patients that experienced LAMS migration, 3 required surgery, 2 were rescued with esophageal stent bridging and 2 with a second LAMS. Bleeding occurred in 2 patients and was managed endoscopically at the time of the procedure. No deaths occurred in the cohort. Conclusions: Same day EDGE procedures can be performed safely with an acceptable complication rate. Larger diameter 20mm stents are the strongest predictor of a non-migrated LAMS, whereas stent fixation and dilation after deployment may also improve procedural success. Expanding on this cohort will offer further insights into the optimal technique for single-session EDGE
