Should you #DeleteAcademiaEdu?: on the role of commercial services in scholarly communication.

Reflecting on the recent surge of criticism about the commercial motives of scholarly social media platform Academia.edu, Paolo Mangiafico argues this is now an ideal opportunity for scholars to make informed choices about their work. If you are comfortable with the trade-offs and risks, and willing to exchange those for the service provided, then don’t #DeleteAcademiaEdu. But consider whether alternatives exist that will meet your needs while also preserving your ability to keep control of your work

Reason, Risk, and Reward: Models for Libraries and Other Stakeholders in an Evolving Scholarly Publishing Ecosystem

Scholarly publishing, and scholarly communication more generally, are based on patterns established over many decades and even centuries. Some of these patterns are clearly valuable and intimately related to core values of the academy, but others were based on the exigencies of the past, and new opportunities have brought into question whether it makes sense to persist in supporting old models. New technologies and new publishing models raise the question of how we should fund and operate scholarly publishing and scholarly communication in the future, moving away from a scarcity model based on the exchange of physical goods that restricts access to scholarly literature unless a market-based exchange takes place. This essay describes emerging models that attempt to shift scholarly communication to a more open-access and mission based approach and that try to retain control of scholarship by academics and the institutions and scholarly societies that support them. It explores changing practices for funding scholarly journals and changing services provided by academic libraries, changes instituted with the end goal of providing more access to more readers, stimulating new scholarship, and removing inefficiencies from a system ready for change

Making Scholarly Publishing Work for You: Empowering Graduate Students to Understand the Scholarly Publishing Ecosystem Through a Graduate Academy Seminar

Understanding the landscape of scholarly publishing is an essential competency for graduate students, whether they publish during their studies or after they’ve entered their professional fields. But the scholarly publishing ecosystem can be complicated to navigate, and students cannot always rely on their advisors and colleagues to demystify the processes. To help graduate students achieve their goals when sharing their research, the ScholarWorks Center for Scholarly Publishing at the Duke University Libraries (https://scholarworks.duke.edu/) taught “Navigating Scholarly Publishing,” a five-day, interdisciplinary course introducing essential aspects of scholarly communication and empowering students to make informed, proactive decisions about sharing their work. Taught by expert instructors in the ScholarWorks Center as part of Duke’s summer Graduate Academy (https://bit.ly/47ppflT), the course involved introductory readings, short lectures, forum posts, and seminar-style discussion to explore and address student questions on each day’s topic: Day One: Big Picture (copyright, technology, economics, and ethics as lenses for understanding the scholarly publishing ecosystem) Day Two: Synthesizing Your Research (how the desired audience for one’s research can influence how it’s synthesized and shared) Day Three: Publishing Your Work (legal and ethical considerations, such as copyright, licenses, and collaborations; the economics of discoverability; evaluating publishers and publishing options; APCs and subscriptions) Day Four: Measuring and Articulating Value (impact metrics; injustices hidden by research impact; measuring what we value versus valuing what we can measure) Day Five: Creating Scholarship That Lasts (factors helping or hindering accessibility and usefulness for future scholarship) These topics not only educated students about the current state of scholarly publishing but encouraged them to (1) consider the potential audience for their research before they decide how to publish it and (2) identify their own values when it comes to sharing their research. For instance, is equitable access an essential aspect of their professional moral framework? Do they need to select a journal based on impact metrics in order to advance in their career? How can they most appropriately license their work for long-term (re)usability? We invited students to discuss what research dissemination means to them and how they can operate in the current system to their advantage—and how they can make choices that might influence the future of that system. To serve graduate students is to engage them in the wider conversation and empower them to make scholarly publishing work for them. Each of the instructors will discuss their experience teaching this course: curriculum design, learning management tools, classroom interactions, content covered, student feedback, and lessons learned from the first iteration of this course. We will also discuss how our values of student empowerment and participation infused this course, and how we see libraries as critical advocates for improving publishing (rather than simply teaching students about the status quo)

Endoscopic submucosal dissection of gastric neoplastic lesions: An Italian, multicenter study

Endoscopic submucosal dissection (ESD) allows removing neoplastic lesions on gastric mucosa, including early gastric cancer (EGC) and dysplasia. Data on ESD from Western countries are still scanty. We report results of ESD procedures performed in Italy. Data of consecutive patients who underwent ESD for gastric neoplastic removal were analyzed. The en bloc resection rate and the R0 resection rates for all neoplastic lesions were calculated, as well as the curative rate (i.e., no need for surgical treatment) for EGC. The incidence of complications, the one-month mortality, and the recurrence rate at one-year follow-up were computed. A total of 296 patients with 299 gastric lesions (80 EGC) were treated. The en bloc resection was successful for 292 (97.6%) and the R0 was achieved in 266 (89%) out of all lesions. In the EGC group, the ESD was eventually curative in 72.5% (58/80) following procedure. A complication occurred in 30 (10.1%) patients. Endoscopic treatment was successful in all 3 perforations, whereas it failed in 2 out of 27 bleeding patients who were treated with radiological embolization (1 case) or surgery (1 case). No procedure-related deaths at one-month follow-up were observed. Lesion recurrence occurred in 16 (6.2%) patients (6 EGC and 10 dysplasia). In conclusion, the rate of both en bloc and R0 gastric lesions removal was very high in Italy. However, the curative rate for EGC needs to be improved. Complications were acceptably low and amenable at endoscopy

Percutaneous mitral valve repair with the MitraClip system: acute results from a real world setting

This study sought to evaluate the feasibility and early outcomes of a percutaneous edge-to-edge repair approach for mitral valve regurgitation with the MitraClip((R)) system (Evalve, Inc., Menlo Park, CA, USA).Patients were selected for the procedure based on the consensus of a multidisciplinary team. The primary efficacy endpoint was acute device success defined as clip placement with reduction of mitral regurgitation to < 2+. The primary acute safety endpoint was 30-day freedom from major adverse events, defined as the composite of death, myocardial infarction, non-elective cardiac surgery for adverse events, renal failure, transfusion of > 2 units of blood, ventilation for > 48 h, deep wound infection, septicaemia, and new onset of atrial fibrillation. Thirty-one patients (median age 71, male 81%) were treated between August 2008 and July 2009. Eighteen patients (58%) presented with functional disease and 13 patients (42%) presented with organic degenerative disease. A clip was successfully implanted in 19 patients (61%) and two clips in 12 patients (39%). The median device implantation time was 80 min. At 30 days, there was an intra-procedural cardiac tamponade and a non-cardiac death, resulting in a primary safety endpoint of 93.6% [95% confidence interval (CI) 77.2-98.9]. Acute device success was observed in 96.8% of patients (95% CI 81.5-99.8). Compared with baseline, left ventricular diameters, diastolic left ventricular volume, diastolic annular septal-lateral dimension, and mitral valve area significantly diminished at 30 days.Our initial results with the MitraClip device in a very small number of patients indicate that percutaneous edge-to-edge mitral valve repair is feasible and may be accomplished with favourable short-term safety and efficacy results

Endoscopic Submucosal Dissection for Subepithelial Tumor Treatment in the Upper Digestive Tract: A Western, Multicenter Study

Background/aims: Endoscopic submucosal dissection (ESD) has been proposed for removal of gastrointestinal subepithelial tumors (GI-SETs), but data are still scanty. This study aimed to report a case series from a western country. Patients and methods: Data of patients with upper GI-SETs suitable for ESD removal observed in 4 centers were retrospectively reviewed. Before endoscopic procedure, the lesion was characterized by endosonographic evaluation, histology, and CT scan. The en bloc resection and the R0 resection rates were calculated, as well as incidence of complications, and the 1-year follow-up was reported. Results: Data of 84 patients with esophageal (N = 13), gastric (N = 61), and duodenal (N = 10) GI-SETs were collected. The mean diameter of lesions was 26 mm (range: 12-110 mm). There were 17 gastrointestinal stromal tumors, 12 neuroendocrine tumors, 35 leiomyomas, 18 lipomas, and 2 hamartomas. En bloc and R0 resection were achieved in 83 (98.8%) and in 80 (95.2%) patients, respectively. Overall, a complication occurred in 11 (13.1%) patients, including bleeding (N = 7) and perforation (N = 4). Endoscopic approach was successful in all bleedings, but 1 patient who required radiological embolization, and in 2 perforations, while surgery was performed in the other patients. Overall, a surgical approach was eventually needed in 5 (5.9%), including 3 in whom R0 resection failed and 2 with perforation. Conclusions: Our study found that ESD may be an effective and safe alternative to surgical intervention for both benign and localized malignant GI-SETs

Decline in subarachnoid haemorrhage volumes associated with the first wave of the COVID-19 pandemic

BACKGROUND: During the COVID-19 pandemic, decreased volumes of stroke admissions and mechanical thrombectomy were reported. The study\u27s objective was to examine whether subarachnoid haemorrhage (SAH) hospitalisations and ruptured aneurysm coiling interventions demonstrated similar declines. METHODS: We conducted a cross-sectional, retrospective, observational study across 6 continents, 37 countries and 140 comprehensive stroke centres. Patients with the diagnosis of SAH, aneurysmal SAH, ruptured aneurysm coiling interventions and COVID-19 were identified by prospective aneurysm databases or by International Classification of Diseases, 10th Revision, codes. The 3-month cumulative volume, monthly volumes for SAH hospitalisations and ruptured aneurysm coiling procedures were compared for the period before (1 year and immediately before) and during the pandemic, defined as 1 March-31 May 2020. The prior 1-year control period (1 March-31 May 2019) was obtained to account for seasonal variation. FINDINGS: There was a significant decline in SAH hospitalisations, with 2044 admissions in the 3 months immediately before and 1585 admissions during the pandemic, representing a relative decline of 22.5% (95% CI -24.3% to -20.7%, p\u3c0.0001). Embolisation of ruptured aneurysms declined with 1170-1035 procedures, respectively, representing an 11.5% (95%CI -13.5% to -9.8%, p=0.002) relative drop. Subgroup analysis was noted for aneurysmal SAH hospitalisation decline from 834 to 626 hospitalisations, a 24.9% relative decline (95% CI -28.0% to -22.1%, p\u3c0.0001). A relative increase in ruptured aneurysm coiling was noted in low coiling volume hospitals of 41.1% (95% CI 32.3% to 50.6%, p=0.008) despite a decrease in SAH admissions in this tertile. INTERPRETATION: There was a relative decrease in the volume of SAH hospitalisations, aneurysmal SAH hospitalisations and ruptured aneurysm embolisations during the COVID-19 pandemic. These findings in SAH are consistent with a decrease in other emergencies, such as stroke and myocardial infarction
