Purpose
Interprofessional education (IPE), collaboration, and training are essential for health programs at the graduate level, but there are often challenges in implementing initiatives that transcend several departments/schools. Grand Rounds is an interprofessional case-based team-building activity that involves faculty facilitators and students from several health professions. The purpose of the current study was to explore the benefits of Grand Rounds for IPE, particularly among graduate students, and share the academic process and experience in developing IPE activities.

Method
Program directors were asked to e-mail surveys to eligible students inviting them to attend the Grand Rounds event; those who participated in the event were sent a follow-up survey.

Results
One hundred twenty-two faculty and students attended the event; 81 were graduate students. The data from graduate students' preevent and postevent surveys were analyzed. Students' knowledge of their own professions and those of others was enhanced as a result of participation in the Grand Rounds event.

Conclusion
The results indicate that Grand Rounds is a promising activity for IPE and a potential tool for cultivating interprofessional collaborations in higher education.

Published: April 2019

Climate change impacts viticulture with even stronger effects on sparkling wines. Innovative cultural practices represent effective short-term solutions. Among these, postponement of winter pruning later than budburst delayed both vegetative and reproductive cycles as well as technological maturity of several varieties from different wine regions. This research aims to assess the impact of delayed winter pruning on grapevine performance as a function of training system.The trial was carried out in a Pinot Noir vineyard sited at 385 m asl in Central Italy. Delayed winter pruning was performed when unpruned canes had shoots showing three unfolded leaves (BBCH 13) and compared to standard winter pruning within two separate experiments focused on: i) cane pruning, and ii) spur pruning. Grapevine phenology, vegetative growth, fruit ripening kinetics and productivity of selected vines were assessed over three years. Delayed winter pruning postponed budburst by 20 and 31 days in Guyot and spur pruned cordons, respectively; then, differences diminished over time showing a maximum delay of 17 days at bloom and 7–10 days at harvest. Despite a decrease in yield (ranging from −35 to −47% in cane and spur pruning, respectively), delayed winter pruning increased titratable acidity (40–89%) and reduced sugars (721%) as compared to control vines. Although effects of delayed pruning were stronger in spur pruned vines, delayed winter pruning was effective also on cane-pruned vines, therefore adapting to varieties marked by low basal-node fruitfulness
Hétéro-nucléation de cristaux de neige carbonique au débouchage d’une bouteille de champagne

Published: April 2019

Le débouchage d’une bouteille de champagne permet de revisiter la physique des changements de phase qui accompagnent la détente adiabatique du volume de gaz sous pression dans le col de la bouteille.
On s’intéresse ici aux phénomènes de condensation qui apparaissent dans le sillage du bouchon qui saute, en fonction de la température de ladite bouteille. Pour les bouteilles stockées à 20 °C, un panache bleu azur apparait dans le col de la bouteille et dans le sillage du bouchon qui saute. Il s’évanouit au bout de quelques millisecondes.
On montre que ce panache bleu est la signature de la transformation en cristaux de neige carbonique et par nucléation hétérogène, de la vapeur de dioxyde de carbone présente dans le col de la bouteille.
Thrombose und Antikoagulation bei Tumorpatienten
Authors: Zydek Barbara , Lindhoff-Last Edelgard 
Published: April 2019

ZUSAMMENFASSUNGBei bis zu 20 % aller Krebspatienten treten venöse Thromboembolien im Krankheitsverlauf auf. Patienten mit aktiver Krebserkrankung, die eine venöse Thrombose erleiden, weisen ein besonders hohes Rezidivthromboserisiko auf und benötigen daher bereits nach dem ersten venösen Thromboseereignis eine langfristige Antikoagulation. Neben dem erhöhten Erst- und Rezidivthromboserisiko besteht jedoch auch gleichzeitig ein erhöhtes Blutungsrisiko unter Antikoagulation. Aktuelle Leitlinien empfehlen niedermolekulare Heparine (NMH) für 3–6 Monate nach Auftreten einer venösen Thrombose bei Patienten mit aktiver Krebserkrankung, da diese bei vergleichbarem Blutungsrisiko zu niedrigeren Rezidivthromboseraten im Vergleich zu Vitamin-K-Antagonisten führen. In 2 aktuell publizierten Studien wurde erstmals untersucht, inwiefern direkte orale Antikoagulantien (DOAK) anstelle der NMH eine Therapieoption bei Malignompatienten mit venösen Thrombosen darstellen könnten. Während Thromboserezidive unter DOAK-Therapie seltener auftraten als unter Therapie mit niedermolekularen Heparinen, kam es unter DOAK-Therapie häufiger zu schweren Blutungen, insbesondere gastrointestinalen Blutungen. DOAK stellen daher inzwischen eine neue Alternative zum bisherigen Goldstandard NMH in der Antikoagulation dar, sollten jedoch bei gastrointestinalen Tumoren mit Zurückhaltung und nur nach eingehender Aufklärung des Patienten eingesetzt werden.
Embolischer Schlaganfall unbekannter Quelle (ESUS)
Authors: Ziemann Ulf 
Published: April 2019

ZUSAMMENFASSUNGESUS (embolischer Schlaganfall unbekannter Quelle) wurde als pathogenetisches Konzept mit der Erwartung entwickelt, dass eine orale Antikoagulation wirksamer als eine Thrombozytenfunktionshemmung einen erneuten Schlaganfall verhindern kann. Zwei pivotale Phase-III-Studien (NAVIGATE ESUS, RE-SPECT ESUS) haben diese Erwartung nicht bestätigt. ESUS ist keine singuläre pathogenetische Entität. Zukünftige Konzepte müssen das berücksichtigen, um einer personalisierten Therapie den Weg zu ebnen.
Was gibt es Neues zum Aspirin?
Authors: Hoffmeister Hans Martin 
Published: April 2019

ZUSAMMENFASSUNGIm Gegensatz zur Sekundärprophylaxe verschiedenster kardiovaskulärer Erkrankungen ist die Bedeutung von Aspirin in der Primärprophylaxe nicht eindeutig geklärt. Problematisch für die Klärung dieser Fragestellung ist bereits die Trennung zwischen Primär- und Sekundärprophylaxe. In den letzten Monaten sind mehrere Studien erschienen, die sich mit Aspirin in der Primärprohylaxe befasst haben: Die ARRIVE-Studie, die ASCEND-Studie und die ASPREE-Studie. Insgesamt zeigen diese Studien, dass Aspirin 100 mg/Tag bei Personen mit einem niedrigen oder niedrig-mäßigen Risiko keinen durchschlagenden positiven Effekt in der Primärprophylaxe kardiovaskulärer Erkrankungen besitzt. Dagegen manifestieren sich die mit Aspirin-assoziierten Nebenwirkungen unabhängig vom kardiovaskulären Risiko. Anders ist die Situation bei Personen mit hohem kardiovaskulären Risiko: Hier gibt es in der Regel zu Studienbeginn bereits fortgeschrittene vaskuläre und andere Veränderungen. In dieser noch nicht abschließend eindeutig zu beurteilenden Situation sollten der Patientenwunsch und das individuelle Blutungsrisiko berücksichtigt werden.

Published: April 2019

Background Valve-sparing aortic root replacement (VSARR) is an increasingly popular alternative to traditional aortic root replacement for aortic root aneurysm disease with a normal aortic valve. We evaluated the early and midterm outcomes of VSARR—reimplantation technique (VSARR-RT) done at a single institution over a decade.
Materials and Methods We performed a retrospective study of all patients who underwent VSARR-RT between January 2004 and July 2014.
Results A total of 85 patients underwent VSARR-RT. Median time to latest echocardiographic follow-up was 4 years (range: 15–72 months). Total observation time was 491 patient years. Mean age was 44.6 ± 14.3 years, and 13 (15%) were women. Thirty-nine (46%) patients had a connective tissue disorder and 6 (7%) had a bicuspid aortic valve. Thirty-three (39%) patients underwent concomitant procedures, including coronary artery bypass grafting (n = 9, 11%), mitral valve repair (n = 8, 9%), and aortic hemi-arch replacement (n = 7, 8%). There were no operative deaths or in-house mortality and no postoperative strokes. Kaplan-Meier analysis demonstrated survival of 99% (95% confidence interval [CI]: 97–100%) at 2 years and 98% (95% CI: 97–100%) at 8 years. Freedom from reoperation was 95.8% (95% CI: 91.2–100%) at 8 years. Freedom from endocarditis was 100% at 8 years. At the last echocardiographic follow-up, 95% of patients were free of severe aortic regurgitation (AR) and 82% free of moderate AR. Of the four patients who had severe AR, three underwent reoperations and received prosthetic valves and one is being clinically monitored.
Conclusion This study reports early and midterm outcomes after VSARR-RT at our institution, including those patients who underwent a VSARR-RT procedure combined with other procedures. Further follow-up remains necessary to determine long-term outcomes.

Published: April 2019

AbstractA 69-year-old man presented with precordial pain and a dilated ascending aorta with the suspicion of an intramural hematoma. At emergency operation, the aorta appeared grossly thickened with diffuse intimal scarring. Retrospectively, the patient tested positive to serologic screening for syphilis with histologic findings also compatible with a syphilitic aortitis.
Esophageal Atresia and Thenar Hypoplasia Associated with Asymmetric Crying Face

Published: April 2019

AbstractAsymmetric crying face (ACF) is a minor congenital anomaly that is often associated with a high rate of major malformations and may be considered an indication of a syndromic clinical presentation. Here, we report a 21-month-old male presenting with left- sided ACF, thenar hypoplasia, and esophageal atresia. Ultrasonographic images of the volar surface of the left hand evidenced the absence of muscle tissue around the thenar prominence at the level of the first metacarpal bone. No pathogenic copy number variation was detected on array-comparative genomic hybridization analysis (CGH). The association of esophageal atresia, thenar hypoplasia, and ACF has not been reported before. We discuss the possibility of a distinct association or of a sequence of anomalies associated with ACF.

SignificanceProvision of sufficient activating signals can drive self-tolerant T cells to cross-react on self-peptide-MHC in a breakdown of tolerance. This approach has been applied in the development of heteroclitic peptide vaccines, which retain sufficient similarity to self to allow reactivation of effector cells on unaltered self-epitopes but require detailed knowledge about the behavior of individual altered self-peptide antigens. We designed altered-self MHC mutant antigen-presenting molecules to drive CTL capable of cross-reacting on self-peptide-MHC and demonstrate the breaking of self-tolerance to defined and undefined self-antigens. These findings bear particular importance in the field of cancer immunotherapy in which breaking tolerance to weakly antigenic cancer-associated antigens is fundamental to vaccination strategies.
Indexical ‘mismatch’; or, adaptability at work
Authors: Verschueren Jef 
Published: April 2019

Abstract
This epilogue reflects on the notions of ‘irregularity’ and ‘mismatch’ which form the leitmotiv for this issue on perspectivization in language use, and more specifically on perspective shift and perspective persistence. While endorsing the approach, it is suggested that, given the complexities involved (who orients to what aspects of context and how?) any stable form-function coding would probably fail to perform the communicative task at hand, so that adaptable structures and processes are predictable. It is also pointed out that the observed irregularities seem to show a high degree of persistence across time and space, and it is suggested that this ‘regularity’ may be the most useful focus for this type of research.
Mudge's Medley Concerto
Authors: Gibson Ronnie , Talbot Michael 
Published: April 2019

AbstractA previously unnoticed concerto for two horns and strings published anonymously in London probably in late 1757 or 1758 is attributable to Richard Mudge (1718–63), a clergyman-composer best known for his Six Concertos in Seven Parts. The print names it A Concerto Principally Form'd upon Subjects Taken from Three Country Dances, and there is evidence to suggest that it is identical to the Medley Concerto listed elsewhere under Mudge's name. The concerto can in turn be linked to so-called ‘Medley Concerts’ that took place in London in 1757. The country dances, on whose material Mudge draws with obvious respect for the originals, are all Scottish tunes found in James Oswald's slightly earlier collections. Mudge's original and attractive work testifies to the great interest in Scottish, in particular ‘Highland’, music in mid-eighteenth-century London, prompting reflection on the many-sided and surprisingly intimate relationship that then existed between traditional music and art music.
Remediating Modernism: On the Digital Ends of Montreal's Electroacoustic Tradition
Authors: Valiquet Patrick 
Published: April 2019

AbstractThis article examines ongoing efforts to associate the decline of the modernist electroacoustic music tradition with the rise of digital technologies. Illustrative material is drawn from ethnographic and archival fieldwork conducted in 2011 and 2012 in the Canadian city of Montreal. The author surveys examples of institutions, careers, performances and works showing how the digital is brought into the ideological service of existing musical orders and power structures by musicians, policy-makers and other intermediaries. Drawing upon the social theories of Pierre Bourdieu and Georgina Born, as well as on contemporary media theory, the author argues that accounts of the disruptive agency of digital mediation are incomplete without a corresponding attention to the complex cultural mechanisms by which it is kept under control. What is at stake in the transformation of Montreal's electroacoustic tradition is not a collapse so much as a further remediation of modernist social and aesthetic principles.
Proposed experiments to detect keV-range sterile neutrinos using energy-momentum reconstruction of beta decay or K-capture events
Authors: Smith Peter F 
Published: April 2019

Abstract
Sterile neutrinos in the keV mass range may constitute the galactic dark matter. Various proposed direct detection and laboratory searches are summarized. It is suggested that a promising method for searching for keV sterile neutrinos in the laboratory is complete energy-momentum reconstruction of individual beta-decay or K-capture events, by measuring the vector momentum of all decay products from atoms suspended in a magneto-optical trap. Reconstruction of the ‘missing mass’ would isolate any keV-range sterile neutrinos as a separated population. A survey of suitable nuclides is presented, together with the measurement precision required in a typical experimental configuration. Among the most promising are the K-capture nuclides 131Cs, which requires measurement of an x-ray and several Auger electrons in addition to the atomic recoil, and 7Be which has only a single decay product but needs development work to achieve a trapped source. A number of background effects are discussed. It is concluded that, with current time-of-flight precision, sterile neutrinos with masses down to the 10 keV region would be detectable with relative couplings 10−5–10−6 in a 1–2 year running time, and with foreseeable future upgrades eventually able to reach coupling levels down to 10−10–10−11 using high-population trapped sources.

Abstract
Determining the scattering potential landscape for two-dimensional superlattices provides key insight into fundamental quantum electron phenomena. Theoretical and semiempirical methods have been extensively used to simulate confinement effects of the two-dimensional electron gas (2DEG) on superlattices with a single scatterer in the form of vicinal surfaces and dislocation networks or isolated structures such as quantum corrals and vacancy islands. However, the complexity of the problem increases when the building blocks (or scatterers) are heterogeneous, as in metal-organic nanoporous networks (MONNs), since additional potentials may come into play. Therefore, the parametrization of the surface potential landscape is often inaccurate, leading to incorrect scattering potentials. Here, we address this issue with a combination of scanning tunneling microscopy/spectroscopy, angle resolved photoemission spectroscopy and Kelvin probe force microscopy measurements together with electron plane-wave expansion simulations on a MONN grown on Cu(111). This experimental-theory approach, enables us to capture the 2DEG response to the intricate scattering potential landscape, and reveals systematic modeling procedures. Starting from a realistic geometry of the system, we determine the repulsive scattering potentials for both molecules and coordinated metal adatoms, the latter contradicting the established simulation framework. Moreover, we reveal local asymmetries and subtle renormalization effects of the 2DEG that relate to the interaction of the MONN and the underlying substrate.
Computational analysis of vibrational spectrum and hydrogen bonds of ice XVII

Abstract
Based on first-principles density functional theory, we investigated the relationship between the vibrational normal modes and the spectrum of the newest laboratory-prepared ice phase, an empty clathrate hydrate structure from gas hydrate named ice XVII. A 48-molecule supercell was designed to mimic the hydrogen-disordered structure. Despite its much lower density than ice Ih, its phonon density of states shows features very similar to those of that phase. In our previous studies of ice Ic and ice XIV, we found two basic hydrogen bond vibrational modes in these hydrogen-ordered ice phases, which contribute two sharp hydrogen bond peaks in the translation region. In this study, we found that this rule also holds in the hydrogen-disordered phase ice XVII. A water molecule vibrating along its angle bisector possesses strong energy, because this vibrational mode involves oscillation against four bonded neighbors. In contrast, a water molecule vibrating perpendicular to its angle bisector has low energy because this mode involves only two of the molecule’s hydrogen bonds. This is an evidence in hydrogen-disordered ice and strengthens our proposal that the existence of two basic hydrogen bond vibrational modes is a general rule among ice family.
Unknown spin radiation
Authors: Khrapko R 
Published: April 2019

Abstract
When the canonical spin tensor is used, a spin is detected along the axis of rotation of a rotating electric dipole. Early this spin radiation was obtained by Feynman in the frame of quantum mechanics. The magnitude of the spin flux is half the flux of the angular momentum that is emitted by a rotating dipole, according to modern electrodynamics, and this angular momentum flux is recognized here as an orbital angular momentum. Thus, the total angular momentum flux exceeds 1.5 times the value now recognized. It is shown that the torque experienced by a rotating dipole from the field is equal in magnitude to this total angular momentum flux.
Gender and Editorial Authorship in High-Impact Epidemiology Journals
Authors: Qureshi Riaz , Lê Jimmy , Li Tianjing , Ibrahim Michel , Dickersin Kay 
Published: April 2019

Abstract
Women comprise about half of senior epidemiologists, but little is known about whether they are also viewed as leaders (i.e., authorities) in the field. We believe editorial roles are markers of leadership in a field. Our objective was to describe the distribution of gender across authorship of editorials published in 5 high-impact epidemiology journals over the past 8 years. We included editorials and commentaries published in American Journal of Epidemiology, European Journal of Epidemiology, Epidemiology, International Journal of Epidemiology, and Journal of Clinical Epidemiology between 2010 and 2017. We classified genders of all authors as woman, man, or unknown and computed the proportions of women editorial authors over all journals and according to position (e.g., first author). Only 31% (682/2,228) of all editorial authors and 36% (524/1,477) of unique editorial authors (i.e., counting each editorial author name only once) were women. We identified 1,180 editorials; 594 had sole authors, 24% (141/594) of whom were women, and 586 had 2 or more authors, 31% (184/586) of which had women as first authors. If women are underrepresented as editorial authors across epidemiology journals (e.g., as a marker of epidemiology leadership), the situation merits immediate correction.

Published: April 2019

Abstract

Objective
The purpose of this experimental pilot study was to evaluate whether distraction can affect results of performance validity testing.

Method
Thirty-three veterans who have served in the US military since 09/11/2001 (Mage = 38.60, SD = 10.85 years) completed the Test of Memory Malingering (TOMM), Trail Making Test, and Medical Symptom Validity Test (MSVT). Subjects were randomly assigned to complete the MSVT in one of three experimental conditions: standard administration, while performing serial 2 s (Cognitive Distraction), and while submerging a hand in ice water (Physical Distraction).

Results
All participants included in primary analyses passed the TOMM (n = 30). Physical distraction did not affect performance on the MSVT. Cognitive distraction negatively affected MSVT performance.

Conclusions
Cognitive distraction can substantially affect MSVT performance in a subgroup of individuals. Physical distraction did not significantly affect MSVT performance.
