Electrodiagnostic errors contribute to chronic inflammatory demyelinating polyneuropathy misdiagnosis
Authors: Allen Jeffrey A. , Ney John , Lewis Richard A. 
Published: October 2017

ABSTRACTIntroductionDocumentation of peripheral nerve demyelination is an important part of the chronic inflammatory demyelinating polyneuropathy (CIDP) diagnostic process.MethodsWe performed a retrospective analysis of patients referred with a diagnosis of CIDP who were found to have a different condition. Electrodiagnostic study data and interpretations formulated at the time of the initial diagnosis were compared to those obtained during the reevaluation.ResultsThirty‐nine of 86 patients were found not to have CIDP. Initial electrodiagnostic data quality was generally acceptable, but initial electrodiagnostic conclusions were confirmed in only 45% of misdiagnosed studies.DiscussionVulnerability to interpretive errors increases when amplitude‐dependent slowing occurs with length‐dependent axonal neuropathies or motor neuron disease, amplitude‐independent slowing occurs in diabetic patients, fibular nerve to extensor digitorum brevis (EDB) muscle findings are the focal diagnostic abnormality, conduction block is absent, conduction velocity (CV) slowing is limited to compressible sites, and accurate electrodiagnostic interpretations are dismissed in favor of equivocal clinical and cerebrospinal fluid findings.

ABSTRACTIntroductionSince the late 1980s, critical illness myopathy (CIM) and critical illness polyneuropathy (CIP) have been increasingly recognized in the intensive care unit (ICU). We explored whether these causes of ICU weakness were now more likely to lead to electrodiagnostic studies (EDX) at our institution than they were 19–20 years earlier.MethodsWe reviewed 100 consecutive ICU patients who underwent EDX from 2009 to 2015 and compared them to a previously reported study population from 1990–1995.ResultsThirty‐seven (39%) had CIM, CIP, or both versus 55% in the previous study (P = 0.04). Thirty‐four (36%) were diagnosed with “traditional” pre‐ICU causes of weakness, such as motor neuron disease or Guillain‐Barre syndrome, versus 29% in the earlier study (P = 0.3).DiscussionCIM and CIP continue to be common disorders that lead to ICU EDX, but their proportion declined compared with 19–20 years earlier, possibly due to the perceived role and selective use of EDX in the ICU.

Published: October 2017

BackgroundPeptidergic nerve fibers provide important contributions to urethral function. Urethral innervation of female mice is not well documented.AimsTo determine the distribution and projection sites of nerve fibers immunoreactive for vasoactive intestinal peptide (VIP), calcitonin gene‐related peptide (CGRP), substance P (SP), and neuropeptide Y (NPY) in the urethra of wild‐type control mice and compare innervation characteristics between the proximal and distal urethra of young nullipara and older multipara mice. Furthermore, to identify the location and neurochemical coding of the spinal afferent nerve endings in the urethra, whose sensory neurons reside in lumbosacral dorsal root ganglia (DRG).MethodsMultiple labeling immunohistochemistry of urethral sections of nulliparous (6‐8 weeks old), and multiparous (9‐12 months old) mice, and anterograde axonal tracing from L5‐S2 (DRG) in vivo.ResultsAbundant VIP‐, CGRP‐, SP‐, and NPY‐immunoreactive nerve fibers were identified in the adventitia, muscularis, and lamina propria of proximal and distal segments of the urethra. A proportion of fibers were closely associated with blood vessels, glands, and cells immunoreactive for PGP9.5. The epithelium contained abundant nerve fibers immunoreactive for CGRP and/or SP. Epithelial innervation was increased in the distal urethra of multipara mice. Abundant fibers were traced from L5‐S2 DRG to all urethral regions.ConclusionsWe present the first identification of spinal afferent endings in the urethra. Peptidergic nerve fibers, including multiple populations of spinal afferents, provide rich innervation of the female mouse urethra. The morphology of fibers in the epithelium and other regions suggests multiple nerve‐cell interactions impacting on urethral function.
A semidefinite program approach for computing the maximum eigenvalue of a class of structured tensors and its applications in hypergraphs and copositivity test

Published: October 2017

SummaryFinding the maximum eigenvalue of a symmetric tensor is an important topic in tensor computation and numerical multilinear algebra. In this paper, we introduce a new class of structured tensors called W‐tensors, which not only extends the well‐studied nonnegative tensors by allowing negative entries but also covers several important tensors arising naturally from spectral hypergraph theory. We then show that finding the maximum H‐eigenvalue of an even‐order symmetric W‐tensor is equivalent to solving a structured semidefinite program and hence can be validated in polynomial time. This yields a highly efficient semidefinite program algorithm for computing the maximum H‐eigenvalue of W‐tensors and is based on a new structured sums‐of‐squares decomposition result for a nonnegative polynomial induced by W‐tensors. Numerical experiments illustrate that the proposed algorithm can successfully find the maximum H‐eigenvalue of W‐tensors with dimension up to 10,000, subject to machine precision. As applications, we provide a polynomial time algorithm for computing the maximum H‐eigenvalues of large‐size Laplacian tensors of hyperstars and hypertrees, where the algorithm can be up to 13 times faster than the state‐of‐the‐art numerical method introduced by Ng, Qi, and Zhou in 2009. Finally, we also show that the proposed algorithm can be used to test the copositivity of a multivariate form associated with symmetric extended Z‐tensors, whose order may be even or odd.

Data assimilation (DA) methods for convective‐scale numerical weather prediction at operational centres are surveyed. The operational methods include variational methods (3D‐Var and 4D‐Var), ensemble methods (LETKF) and hybrids between variational and ensemble methods (3DEnVar and 4DEnVar). At several operational centres, other assimilation algorithms, like latent heat nudging, are additionally applied to improve the model initial state, with emphasis on convective scales. It is demonstrated that the quality of forecasts based on initial data from convective‐scale DA is significantly better than the quality of forecasts from simple downscaling of larger‐scale initial data. However, the duration of positive impact depends on the weather situation, the size of the computational domain and the data that are assimilated. Furthermore it is shown that more advanced methods applied at convective scales provide improvements over simpler methods. This motivates continued research and development in convective‐scale DA.Challenges in research and development for improvements of convective‐scale DA are also reviewed and discussed. The difficulty of handling the wide range of spatial and temporal scales makes development of multi‐scale assimilation methods and space–time covariance localization techniques important. Improved utilization of observations is also important. In order to extract more information from existing observing systems of convective‐scale phenomena (e.g. weather radar data and satellite image data), it is necessary to provide improved statistical descriptions of the observation errors associated with these observations.
The double sampling range chart
Authors: Costa Antonio 
Published: October 2017

AbstractThe R chart and the S2 chart are the usual charts for monitoring process dispersion; however, the double sampling (DS) scheme has only be used with the S2 chart. The difficulty in obtaining the properties of the DS R chart might explain the lack of papers dealing with this type of DS chart. The S2 chart has the advantage of being more efficient than the R chart, but the same is not always observed with their DS versions. Depending on the size of the 2 samples, the DS R chart performs better. The trade‐off between operational simplicity and power of detection might lead the practitioner to choose the DS R chart, even with the DS S2 chart signaling faster.

AbstractBackgroundThe stereo laparoscope is an important tool for achieving depth perception in robot‐assisted minimally invasive surgery (MIS).MethodsA dynamic convergence accommodation algorithm is proposed to improve the viewing experience and achieve accurate depth perception. Based on the principle of the human vision system, a positional kinematic model of the binocular view system is established. The imaging plane pair is rectified to ensure that the two rectified virtual optical axes intersect at the fixation target to provide immersive depth perception.ResultsStereo disparity was simulated with the roll and pitch movements of the binocular system. The chessboard test and the endoscopic peg transfer task were performed, and the results demonstrated the improved disparity distribution and robustness of the proposed convergence accommodation method with respect to the position of the fixation target.ConclusionsThis method offers a new solution for effective depth perception with the stereo laparoscopes used in robot‐assisted MIS.

The lithiated/delithiated vanadium pentoxide films deposited by sol‐gel spin coating on indium tin oxide–coated glass substrates were analyzed by sputter‐induced photon spectroscopy, X‐ray diffraction, and optical absorption techniques. First, it is shown that the crystalline structure of V2O5 after intercalation remains practically unchanged. Particularly, in the optical spectra during 5 keV Kr+ ion bombardment of clean, intercalated, and deintercalated V2O5 films, a series of sharp lines and unexpected continuum radiation were observed and well explained. It is also demonstrated that the intercalation and deintercalation of lithium have strong influences on various characteristics of pentoxide vanadium. The interpretations of the obtained results in the 3 experiments—X‐ray diffraction, sputter‐induced photon spectroscopy, and optical absorption techniques—are coherent and complement each other.

Published: October 2017

Potassium permanganate was applied to improve the surface properties of the ultra‐high molecular weight polyethylene (UHMWPE) fibers. The results suggested that the surface oxygen atoms increased dramatically and the O/C ratio increased from 0.030 to 0.563 after treatment. The increased surface roughness and the O‐containing groups on the treated fiber surface decreased the contact angles with water and ethylene glycol. The crystallinity and the crystallite size of the treated fibers increased, and the DSC results indicated that chain scission and the formation of ―C═O chemical defects in the amorphous region were the main mechanisms of the deterioration of the treated UHMEPE fibers. The breaking strength and the elongation at break of the fibers decreased, but the modulus increased after treatment. The treated fibers exhibited better adhesion with epoxy matrix. An improvement of 27.6% from 101.4 to 129.4 MPa in ILSS confirmed the improvement in the interfacial adhesion strength of composites. The impact and bending strength of composites were both improved.

AbstractBackgroundThe American College of Surgeons has always promoted education and collaborations with other countries and their scientific organizations. The International Guest Scholarship program was established in 1968 to support the travel of foreign surgeons to medical Institutions in the USA and Canada. The program has grown substantially over time and now includes different categories of scholarships and surgeons. The objective of this article is to describe the experiences gained by the international scholars who visited US and Canadian institutions through these ACS programs.Study designIn order to collect information regarding these scholarships from the surgeons who have already participated in the program, an Internet‐based survey was e‐mailed to alumni. The surveys were constructed to gather career information on former scholars and to analyze the perceived impact of these programs on their careers.ResultsAmong the international scholarships alumni, most are now Fellows of the American College of Surgeons. The majority of respondents maintained contact with their host surgeons in the USA or Canada; they began or continued research, surgical education and surgical quality improvement initiatives in their country of origin based upon their experiences as international scholars. Most of the alumni reported that the experience they had during the scholarship was inspiring, opened their minds and broadened their horizons.ConclusionsThe overall effect of ACS international scholarship program should be considered as positive, as 80–90% of respondent alumni consider their experience very helpful and feel that it provided them with opportunities that would not have been possible without it. It is incumbent upon the ACS to continue along this path by identifying funding and donation sources, as well as enriching the content and goals.

AbstractAs of May 2017, there were 4242 Certified Genetic Counselors (CGC) (American Board of Genetic Counseling, Inc. 2017) and 41 graduate‐level genetic counseling training programs (Accreditation Council for Genetic Counseling 2017) in North America, and the demand for CGCs continues to increase. In the Fall of 2015 the Genetic Counselor Workforce Working Group, comprised of representatives from the American Board of Genetic Counseling (ABGC), the Accreditation Council for Genetic Counseling (ACGC), the Association of Genetic Counseling Program Directors (AGCPD), the American Society of Human Genetics (ASHG), and the National Society of Genetic Counselors (NSGC) commissioned a formal workforce study to project supply of and demand for CGCs through 2026. The data indicate a shortage of genetic counselors engaged in direct patient care. Assuming two scenarios for demand, supply is expected to reach equilibrium between 2024 and 2030. However, given the rate of growth in genetic counseling training programs in the six months since the study was completed, it is reasonable to expect that the number of new programs may be higher than anticipated by 2026. If true, and assuming that growth in programs is matched by equivalent growth in clinical training slots, the supply of CGCs in direct patient care would meet demand earlier than these models predict.

BackgroundPrecision medicine approach holds great promise to tailored diagnosis, treatment and prevention. Individuals can be vastly different in their genomic information and genetic mechanisms hence having unique transcriptomic signatures. The development of precision medicine has
demanded moving beyond DNA sequencing (DNA‐Seq) to much more pointed RNA‐sequencing (RNA‐Seq) [ Cell, 2017, 168: 584–599].ResultsHere we conduct a brief survey on the recent methodology development of transcriptome assembly approach using RNA‐Seq.ConclusionsSince transcriptomes in human disease are highly complex, dynamic and diverse, transcriptome assembly is playing an increasingly important role in precision medicine research to dissect the molecular mechanisms of the human diseases.
Transatlantic Contrafacta, Musical Formats, and the Creation of Political Culture in Revolutionary America
Authors: GOODMAN GLENDA 
Published: October 2017

AbstractThis article investigates Revolutionary-era American political culture through contrafacta of the British anthem “God Save the King.” Before, during, and after the Revolution the tune was frequently set with new lyrics that addressed political topics. The formats through which the song circulated (it was disseminated widely in manuscript and print), shaped the meaning and reception of these various contrafacta. Tracking “God Save the King” through the eighteenth century reveals how the United States remained connected to Britain, even when the lyrics—and the goals of the Revolution—repudiated that bond. Song versions also provide a musical map of the fragmenting political landscape of the early Republic. Ultimately, the diversity of the formats and the song versions reveal the ambivalent relationship between postcolonial United States and Britain, as well as the diversity of political culture within the United States.
“Yes, [Gospel] Is Real”: Half a Century with Chicago's Martin and Morris Company
Authors: NORTON KAY 
Published: October 2017

AbstractThe Martin and Morris Music Studio (MMMS) imprint permeated the first fifty years of black gospel music. Jointly owned by singer/impresaria Sallie Martin (1895/6–1988) and composer/arranger/pianist/organist Kenneth Morris (1917–88), the MMMS delivered gospel songs to an eager public and offered ordinary Americans the chance to see their names in print as author or composer on the cover of a gospel octavo, copies of which could then be sold to benefit that same ordinary American. Their influence extended far beyond that service, however. Martin and her Singers performed and popularized music bearing the MMMS imprint in venues ranging from small churches in the Deep South to national conventions in Washington, D.C., and widened circulation of MMMS music via Los Angeles recording studios. The unprecedented accomplishments of the MMMS, active from 1940 to 1993, have not been fully explored. Relying on transcribed interviews of the owners by Bernice Johnson Reagon, James Standifer, and others, accounts in historical newspapers, and company archives, this article addresses that void. The centrality of the MMMS in twentieth-century gospel of all types is clarified through examination of contexts for black-owned music publishing in the last century, the owners’ early business models, and their changing roles in the creation, publication, popularization, and dissemination of gospel music for more than fifty years.
Performing Catfish Row in the Soviet Union: The Everyman Opera Company andPorgy and Bess, 1955–56
Authors: UY MICHAEL SY 
Published: October 2017

AbstractFor three weeks in 1955 and 1956 the Everyman Opera Company stagedPorgy and Bessin Leningrad and Moscow. In the previous two years, the Robert Breen and Blevins Davis production of Gershwin's opera had toured Europe and Latin America, funded by the U.S. State Department. Yet when Breen negotiated a performance tour to Russia, the American government denied funding, stating, among other reasons, that a production would be “politically premature.” Surprisingly, however, the opera was performed with the Soviet Ministry of Culture paying the tour costs in full. I argue that this tour, negotiated amid the growing civil rights movement, was a non-paradigmatic example of cultural exchange at the beginning of the Cold War: an artistic product funded at different times byboththe United Statesandthe Soviet Union. Through an examination of the tour's archival holdings, interviews with surviving cast members, and the critical reception in the historically black press, this essay contributes to ongoing questions of Cold War scholarship, including discussions on race, identity, and the unpredictable nature of cultural exchange.
Highly structured prokaryote communities exist within the skeleton of coral colonies
Authors: Marcelino Vanessa R , van Oppen Madeleine J H , Verbruggen Heroen 
Published: October 2017

Abstract
Physiological performance, disease and bleaching prevalence are often patchy within individual coral colonies. These responses are largely influenced by coral-associated microbes, but how the coral microbiome changes over small spatial scales has never been quantified before. We performed a high-resolution quantification of the spatial scale of microbial species turnover (β-diversity) within skeletons of boulder-forming Porites corals. We found very strong prokaryotic species turnover across spatial scales ranging from 4 mm to 2 m within individual colonies, possibly resulting from dispersal limitation and microbial interactions. The microalgal community was more homogeneously distributed, which is likely due to these photosymbionts actively boring through limestone. Our findings highlight unprecedented levels of intra-colony heterogeneity in the skeletal microbiome, which has implications for the experimental design of coral microbiome studies and for our understanding of coral resilience.
