Misinformation, or fake news, has exploded across social media platforms and communities over the past few years, with serious social and political implications. Many library practitioners and organizations have argued that libraries can and should play a central role in educating the public about this emerging issue. However, serious gaps exist in understanding how libraries can create effective community education about misinformation. This article maps out a research agenda that researchers and public library practitioners can use to make libraries more effective sites for combatting misinformation. This research agenda is grounded in analysis of interviews and workshop discussions of public library staff from Washington State. This analysis reveals three areas in which academic partners can support public libraries: through the design of effective programming, through the development of tools that help librarians keep up-to-date on relevant misinformation, and through interventions in the political and economic contexts that hamper the freedom of librarians to engage controversial topics. Our hope is that this article can help to spur more expansive library and information science research across these areas and become the beginning of a longer and more empirically grounded conversation about how public libraries can achieve their potential for combating misinformation.

Objective Emerging off-pump beating heart valve repair techniques offer patients less invasive alternatives for mitral valve (MV) repair. However, most of these techniques rely on the limited spatial and temporal resolution of transesophageal echocardiography (TEE) alone, which can make tool visualization and guidance challenging. Methods Using a magnetic tracking system and integrated sensors, we created an augmented reality (AR) environment displaying virtual representations of important intracardiac landmarks registered to biplane TEE imaging. In a porcine model, we evaluated the AR guidance system versus TEE alone using the transapically delivered NeoChord DS1000 system to perform MV repair with chordal reconstruction. Results Successful tool navigation from left ventricular apex to MV leaflet was achieved in 12 of 12 and 9 of 12 (P = 0.2) attempts with AR imaging and TEE alone, respectively. The distance errors of the tracked tool tip from the intended midline trajectory (5.2 ± 2.4 mm vs 16.8 ± 10.9 mm, P = 0.003), navigation times (16.7 ± 8.0 seconds vs 92.0 ± 84.5 seconds, P = 0.004), and total path lengths (225.2 ± 120.3 mm vs 1128.9 ± 931.1 mm, P = 0.003) were significantly shorter in the AR-guided trials compared with navigation with TEE alone. Furthermore, the potential for injury to other intracardiac structures was nearly 40-fold lower when using the AR imaging for tool navigation. The AR guidance also seemed to shorten the learning curve for novice surgeons. Conclusions Augmented reality–enhanced TEE facilitates more direct and safe intracardiac navigation of the NeoChord DS tool from left ventricular apex to MV leaflet. Tracked tool path results demonstrate fourfold improved accuracy, fivefold shorter navigation times, and overall improved safety with AR imaging guidance.

Objective For robot-assisted coronary artery bypass graft interventions, surgeons typically use a preoperative thoracic computed tomography scan of the patient to plan the procedure. However, the cardiac anatomy is prone to changes induced perioperatively in the effort to access the heart and surgical targets, which, in turn, may invalidate the initial plan. This article presents a method to estimate the perioperative heart migration, information which can be further exploited to refine the preoperative surgical plan. Methods Tracked transesophageal ultrasound images of four patients’ hearts were acquired at each stage in the procedure: before lung deflation, after lung deflation, and after both lung deflation and CO2 thoracic insufflation. Anatomic features of interest—the mitral and aortic valves—were identified from each dataset, and their movement between the different procedure stages was recorded and used to estimate the global heart displacement. Moreover, the local morphology of the features of interest was investigated to provide insight on the extent of the deformation the heart has undergone during the workflow. Results The study suggested that the heart does undergo substantial displacement—on the order of 10 to 15 mm in each direction (axial, coronal, and sagittal) after lung deflation and CO2 thoracic insufflation. However, no significant differences (P > 0.1) were observed in the morphologic characteristics of the features of interest across the multiple workflow stages, suggesting that local deformations occur at a much smaller scale compared with the global migration. Conclusions The quantification of the perioperatively induced changes is critical to track the displacement of the heart and surgical targets. The recorded migration patterns should not be ignored but rather be used to update the surgical plan to better suit the intraoperative environment.

Une etude de faisabilite a ete faite pour la CEE en vue d'examiner la possibilite de creer un centre d'echange et de compensation international comme aide aux transferts technologiques. Les initiatives recentes et connexes pour promouvoir l'innovation et la communication a l'interieur de la CEE sont decrites. Un projet est propose, reposant sur les activites des agents du transfert de l'information industrielle qui pourraient collecter l'information pour un centre national qui le transfererait au Clearinghouse. En retour, les centres nationaux recevraient l'information des autres etats membres et la diffuseraient vers ses utilisateurs. Une etude par questionnaire sur ce projet a montre que celui-ci etait largement approuve. Des suggestions sont faites pour une evaluation plus poussee de ce projet. (INTD)
