Miscellaneous notes on the genus Forsstroemia in Russia (Neckeraceae, Bryophyta)

Molecular phylogenetic analysis supports the position on the species known as Neckera konoi in the genus Forsstroemia, therefore it is transferred to this genus with a new combination, F. konoi (Broth.) Enroth, Fedosov & Ignatov. Molecular data also confirm the position of F. stricta Laz. described from the Russian Far East in F. producta, a pantropical species. Forstroemia neckeroides is reported from Russia, Primorsky Territory, for the first time.Peer reviewe

On the phylogenetic position of the genus Claopodium: a revival of a 19th century idea

Molecular phylogenetic analysis of nuclear ITS and plastid rps4–trnS found species of the genus Claopodium in the clade formed by species of Brachytheciaceae and Meteoriaceae, including Trachypodaceae. Claopodium is resolved as sister to Brachytheciaceae, thus we suggest its placement in this family, despite it will be the only taxon of the family with pluripapillose laminal cells. The taxonomic value of the papillose leaf cells in pleurocarpous mosses is discussed.</p

Alleniella aegaea Blockeel & Hugonnot (Neckeraceae), a new moss species from the Aegean islands of Greece

A new moss species, Alleniella aegaea (Neckeraceae) is described and illustrated from the Greek islands of Crete, Samos and Evvia based on morphological and molecular evidence. According to phylogenetic analysis of nuclear ITS and plastid trnS-F sequences it is sister to A. complanata, which it also morphologically resembles, but it differs from that species e.g. in its distinctly flattened habit, lack of caducous branchlets, more rounded leaf apices, and shorter median laminal cells. Alleniella aegaea is dioicous and the sporophytes remain unknow

Real World Performance of the 21st Century Cures Act Population Level Application Programming Interface

OBJECTIVE: To evaluate the real-world performance in delivering patient data on populations, of the SMART/HL7 Bulk FHIR Access API, required in Electronic Health Records (EHRs) under the 21st Century Cures Act Rule. MATERIALS AND METHODS: We used an open-source Bulk FHIR Testing Suite at five healthcare sites from April to September 2023, including four hospitals using EHRs certified for interoperability, and one Health Information Exchange (HIE) using a custom, standards-compliant API build. We measured export speeds, data sizes, and completeness across six types of FHIR resources. RESULTS: Among the certified platforms, Oracle Cerner led in speed, managing 5-16 million resources at over 8,000 resources/min. Three Epic sites exported a FHIR data subset, achieving 1-12 million resources at 1,555-2,500 resources/min. Notably, the HIE's custom API outperformed, generating over 141 million resources at 12,000 resources/min. DISCUSSION: The HIE's custom API showcased superior performance, endorsing the effectiveness of SMART/HL7 Bulk FHIR in enabling large-scale data exchange while underlining the need for optimization in existing EHR platforms. Agility and scalability are essential for diverse health, research, and public health use cases. CONCLUSION: To fully realize the interoperability goals of the 21st Century Cures Act, addressing the performance limitations of Bulk FHIR API is critical. It would be beneficial to include performance metrics in both certification and reporting processes

Coulomb dissociation of N 20,21

Neutron-rich light nuclei and their reactions play an important role in the creation of chemical elements. Here, data from a Coulomb dissociation experiment on N20,21 are reported. Relativistic N20,21 ions impinged on a lead target and the Coulomb dissociation cross section was determined in a kinematically complete experiment. Using the detailed balance theorem, the N19(n,γ)N20 and N20(n,γ)N21 excitation functions and thermonuclear reaction rates have been determined. The N19(n,γ)N20 rate is up to a factor of 5 higher at

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

On moss genera Hylocomiadelphus Ochyra & Stebel and Rhytidiadelphus (Limpr.) Warnst.

The moss family Hylocomiaceae is studied for the generic level taxonomy within a molecular phylogenetic approach. We confirm segregating of the species formerly known as Rhytidiadelphus triquetrus to Hylocomiadelphus Ochyra & Stebel from the genus Rhytidiadelphus. Hylocomiadelphus forms a clade with Loeskeobryum and Meteoriella, sharing with both genera cordate to auriculate leaf bases and non-squarrose leaves, and with the former undulate leaves and reticulate exostome teeth ornamentation. However, Loeskeobryum differs from Hylocomiadelphus in having paraphyllia, while Meteoriella has a straight capsule and reduced peristome, likely caused by its epiphytic ecology. In the group of species closely related to R. squarrosus, in addition to R. subpinnatus, the third species with North Pacific distribution is described as R. pacificum. Macrothamnium is found deeply nested in Rhytidiadelphus, although no nomenclatural implications are suggested at the moment due to insufficient sampling. Hylocomium splendens var. splendens and var. obtusifolium were found intermingled in the phylogenetic tree, indicating no correlation between morphology and variation in ITS region, thus supporting a view that these taxa are merely environmentally induced morphs
