16An integrative bioinformatics pipeline shows that honeybee-associated microbiomes are driven primarily by pollen composition显示文摘The microbiomes associated with bee nests influence colony health through various mechanisms,although it is not yet clear how honeybee congeners differ in microbiome assembly processes,in particular the degrees to which floral visitations and the environment contribute to different aspects of diversity.We used DNA metabarcoding to sequence bacterial 16S rRNA from honey and stored pollen from nests of 4 honeybee species(Apis cerana,A.dorsata,A.florea,and A.laboriosa)sampled throughout Yunnan,China,a global biodiversity hotspot.We developed a computational pipeline integrating multiple databases for quantifying key facets of diversity,including compositional,taxonomic,phylogenetic,and functional ones.Further,we assessed candidate drivers of observed microbiome dissimilarity,particularly differences in floral visitations,habitat disturbance,and other key environmental variables.Analyses revealed that microbiome alpha diversity was broadly equivalent across the study sites and between bee species,apart from functional diversity which was very low in nests of the reclusive A.laboriosa.Turnover in microbiome composition across Yunnan was driven predominantly by pollen composition.Human disturbance negatively impacted both compositional and phylogenetic alpha diversity of nest microbiomes,but did not correlate with microbial turnover.We herein make progress in understanding microbiome diversity associated with key pollinators in a biodiversity hotspot,and provide a model for the use of a comprehensive informatics framework in assessing pattern and drivers of diversity,which enables the inclusion of explanatory variables both subtly and fundamentally different and enables elucidation of emergent or unexpected drivers.Douglas Chesters Xiuwei Liu Karen L.Bell Michael C.Orr Tingting Xie Qingsong Zhou Chaodong Zhu 2023Insect Science2023,30,2:0

18Trends in leadership at orthopaedic surgery sports medicine fellowships显示文摘BACKGROUND Fellowship directors(FDs)in sports medicine influence the future of trainees in the field of orthopaedics.Understanding the characteristics these leaders share must be brought into focus.For all current sports medicine FDs,our group analyzed their demographic background,institutional training,and academic experience.AIM To serve as a framework for those aspiring to achieve this position in orthopaedics and also identify opportunities to improve the position.METHODS Fellowship programs were identified using both the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America Sports Medicine Fellowship Directories.The demographic and educational background data for each FD was gathered via author review of current curriculum vitae(CVs).Any information that was unavailable on CV review was gathered from institutional biographies,Scopus Web of Science,and emailed questionnaires.To ensure the collection of as many data points as possible,fellowship program coordinators,orthopaedic department offices and FDs were directly contacted via phone if there was no response via email.Demographic information of interest included:Age,gender,ethnicity,residency/fellowship training,residency/fellowship graduation year,year hired by current institution,time since training completion until FD appointment,length in FD role,status as a team physician and H-index.RESULTS Information was gathered for 82 FDs.Of these,97.5%(n=80)of the leadership were male;84.15%(n=69)were Caucasian,7.32%(n=6)were Asian-American,2.44%(n=2)were Hispanic and 2.44%(n=2)were African American,and 3.66%(n=3)were of another race or ethnicity.The mean age of current FDs was 56 years old(±9.00 years),and the mean Scopus H-index was 23.49(±16.57).The mean calendar years for completion of residency and fellowship training were 1996(±15 years)and 1997(±9.51 years),respectively.The time since fellowship training completion until FD appointment was 9.77 years.17.07%(n=14)of FDs currently work at the same institution where they completed residency training;21.95%(n=18)of FDs work at the same institution where they completed fellowship training;and 6.10%(n=5)work at the same institution where they completed both residency and fellowship training.Additionally,69.5%(n=57)are also team physicians at the professional and/or collegiate level.Of those that were found to currently serve as team physicians,56.14%(n=32)of them worked with professional sports teams,29.82%(n=17)with collegiate sports teams,and 14.04%(n=8)with both professional and collegiate sports teams.Seven residency programs produced the greatest number of future FDs,included programs produced at least three future FDs.Seven fellowship programs produced the greatest number of future FDs,included programs produced at least four future FDs.Eight FDs(9.75%)completed two fellowships and three FDs(3.66%)finished three fellowships.Three FDs(3.66%)did not graduate from any fellowship training program.The Scopus H-indices for FDs are displayed as ranges that include 1 to 15(31.71%,n=26),15 to 30(34.15%,n=28),30 to 45(20.73%,n=17),45 to 60(6.10%,n=5)and 60 to 80(3.66%,n=3).Specifically,the most impactful FD in research currently has a Scopus H-index value of 79.By comparison,the tenth most impactful FD in research had a Scopus H-index value of 43(accessed December 1,2019).CONCLUSION This study provides an overview of current sports medicine FDs within the United States and functions as a guide to direct initiatives to achieve diversity equality.Nicholas C Schiller Andrew J Sama Amanda F Spielman Chester J Donnally III Benjamin I Schachner Dhanur M Damodar Christopher C Dodson Michael G Ciccotti 2021World Journal of Orthopedics2021,12,6:0
19Social media growth of orthopaedic surgery residency programs in response to the COVID-19 pandemic显示文摘BACKGROUND In the Spring of 2020,residency programs across the country experienced rapid and drastic changes to their application process as a result of the coronavirus disease 2019(COVID-19)pandemic.In response,residency programs shifted to virtual events and began harnessing social media to communicate with applicants.AIM To analyze the changes in social media usage by orthopaedic surgery programs in response to the COVID-19 pandemic.METHODS Based on the 2019 residency and fellowship electronic database,accredited US orthopaedic surgery programs were reviewed for social media presence on Instagram and Twitter.Approximately 47000 tweets from 2011-2021 were extracted through the Twitter application programming interface.We extracted:Total number of followers,accounts following,tweets,likes,date of account creation,hashtags,and mentions.Natural language processing was utilized for tweet sentiment analysis and classified as positive,neutral,or negative.Instagram data was collected and deemed current as of August 11,2021.The account foundation date analysis was based on the date recognized as the start of the COVID-19 outbreak in the United States,before or after March 1,2020.RESULTS A total of 85(42.3%)orthopaedic surgery residency program Twitter handles were identified.Thirty-five(41.2%)programs joined Twitter in the nine months after the 2020 covid outbreak.In 2020,there was a 126.6%increase in volume of tweets by orthopaedic surgery residency accounts as compared to 2019.The median number of followers was 474.5(interquartile range 205.0-796.5).The account with the highest number of tweets was Hospital for Special Surgery(@HSpecialSurgery)with 13776 tweets followed by University of Virginia(@UVA_Ortho)with 5063 and Yale(@OrthoAtYale)with 899.Sentiment analysis before 2020 revealed 30.4%positive,60.8%neutral,and 8.8%negative sentiments across tweets.Interestingly,the positive sentiment percentage increased in 2020 from 30.4%to 34.5%.Of the 201 ACGME-accredited orthopaedic residency programs on Fellowship and Residency Electronic Interactive Database,115(57.2%)participate on Instagram,with 101(87.8%)identified as“resident”-managed vs 14(12.2%)identified as“department”-managed.Over three quarters(77.4%)of Instagram accounts were created after March 1,2020.The average number of followers per account was 1089.5 with an average of 58.9 total posts.CONCLUSION Our study demonstrates a substantial growth of Instagram and Twitter presence by orthopaedic surgery residency programs during the COVID-19 pandemic.These data suggest that orthopaedic residency programs have utilized social media as a new way to communicate with applicants and showcase their programs in light of the challenges presented by the pandemic.Joseph S Geller Dustin H Massel Michael G Rizzo Ean Schwartz Jacob Eric Milner Chester J Donnally III 2022World Journal of Orthopedics2022,13,8:0
