Accuracy of Humeral Articular Surface Restoration in a Novel Anatomic Shoulder Arthroplasty Technique and Design: A Cadaveric Study
Authors: Goldberg Steven S , Akyuz Ephraim , Murthi Anand M , Blaine Theodore 
Published: January 2018

Introduction Accurate restoration of the humeral joint line during shoulder arthroplasty is critical to maximizing outcomes. However, clinical studies show that both resurfacing and stemmed arthroplasty systems routinely do not restore the articular surface accurately, even by experienced surgeons. The purpose of this study was to evaluate surgeons’ ability to recreate the 3-dimensional geometry of the proximal humerus using a newly developed arthroplasty system. Methods The difference in articular surface location before and after arthroplasty was measured using a new nonspherical arthroplasty system which uses a calibrated multiplanar osteotomy technique matching bone removal thickness to implant thickness. Eight human cadaver specimens were measured at 9 separate point locations over the articular surface from a fixed reference point on the lateral humerus. We repeated the measurements after bone preparation with the implant trial. Articular surface points >3.0 mm from their original location were considered outliers, based on literature. Results Average absolute deviation of each point on the articular surface measured 0.9 ± 0.7 mm (range: 0.0–2.7 mm) from preoperative to postoperative articular surface location. All (72/72) points measured were below the 3.0 mm outlier threshold from their original location. Conclusion Surgeons using the new system, ie, using a nonspherical head design and a calibrated multiplanar osteotomy surgical technique, were able to restore the joint line accurately with minimal (<1.0 mm) change from preop, with no outliers. Arthroplasty systems matching bone removal directly to implant thickness potentially may improve the reproducibility of arthroplasy and improve shoulder kinematics compared to traditional systems.

AbstractThe new mineral magnesiocanutite (IMA2016-057), NaMnMg2[AsO4]2[AsO2(OH)2], was found at the Torrecillas mine, Iquique Province, Chile, where it occurs as a secondary phase in association with anhydrite, canutite, halite, lavendulan and magnesiokoritnigite. Magnesiocanutite occurs as pale brownish-pink to rose-pink, lozenge-shaped tablets that are often grouped in tightly intergrown aggregates. The crystal forms are {110} and {102}. Crystals are transparent, with vitreous lustre and white to very pale pink streak. The Mohs hardness is 2½, tenacity is brittle, and the fracture is splintery. Crystals exhibit two perfect cleavages: {010} and {101}. The calculated density is 3.957 g/cm3. Optically, magnesiocanutite is biaxial (+), with α = 1.689(2), β = 1.700(2), γ = 1.730(2) (measured in white light); 2Vmeas. = 64.3(4)°; slight dispersion, r <v; orientation Z = b; X ∧ a = 15° in obtuse angle β. The mineral is slowly soluble in dilute HCl at room temperature. Electron-microprobe analyses, provided Na2O 5.44, CaO 0.26, MgO 8.84, MnO 18.45, CoO 1.47, CuO 2.13, As2O5 59.51, H2O(calc) 2.86, total 98.96 wt.%. Magnesiocanutite is monoclinic, C2/c, a = 12.2514(8), b = 12.4980(9), c = 6.8345(5) Å, β = 113.167(8)°, V = 962.10(13) Å3 and Z = 4. The eight strongest powder X-ray diffraction lines are [dobs Å(I )(hkl)]: 6.25(42)(020), 3.566(43)(310,1̄31), 3.262(96)(1̄12), 3.120(59)(002,131,040,221), 2.787(93)(400,022,041,330), 2.718(100) (4̄21,240,112,402), 2.641(42)(1̄32) and 1.5026(43)(multiple). Magnesiocanutite has a protonated alluaudite-type structure (R1 = 2.59% for 789 Fo > 4σF reflections) and is the Mg analogue of canutite. Using the results of both the microprobe analyses and structure refinement, the structurally based empirical formula is Na(Mn0.78Mg0.22)Σ1.00(Mg1.04Mn0.70Cu0.15Co0.11)Σ2.00[AsO4]2[AsO2(OH)2].

Published: January 2018

Background: Diagnoses of respiratory tract infections usually happen in the late phase of the disease and usually result in reduction of the pathogen load after broad-spectrum antibiotic therapy, but not in eradication of the pathogen. The development of a non-invasive, fast, and accurate method to detect pathogens has always been of interest to researchers and clinicians alike. Previous studies have shown that bacteria produce organic gases. The current study aimed to identify the volatile organic compounds (VOCs) produced by three respiratory tract pathogens, including Staphylococcus aureus, Escherichia coli and Candida albicans. Methods: The VOCs produced were identified by gas chromatography–mass spectrometry (GC-MS), with prior collection of microbial volatile compounds using solid phase microextraction (SPME) fiber. The volatile compounds were collected by obtaining bacterial headspace samples. Results: Results showed that these three organisms have various VOCs, which were analyzed under different conditions. By ignoring common VOCs, some species-specific VOCs could be detected. The most important VOC of E. coli was indole, also some important VOCs produced by S. aureus were 2,3-pentandione, cis-dihydro-α-terpinyl acetate, 1-decyne, 1,3-heptadiene, 2,5-dimethyl pyrazine, ethyl butanoate and cyclohexene,4-ethenyl. Furthermore, most of the identified compounds by C. albicans are alcohols. Conclusions: The detection of VOCs produced by infectious agents maybe the key to make a rapid and precise diagnosis of infection, but more comprehensive studies must be conducted in this regard.

Published: January 2018

Background: The phyllosphere hosts a variety of microorganisms, including bacteria, which can play a positive role in the success of the host plant. Bacterial communities in the phylloplane are influenced by both biotic and abiotic factors, including host plant surface topography and chemistry, which change in concert with microbial communities as the plant leaves develop and age.Methods: We examined how theZea maysL. leaf microbial community structure changed with plant age. Ribosomal spacer length and scanning electron microscopic imaging strategies were used to assess microbial community composition across maize plant ages, using a novel staggered experimental design.Results: Significant changes in community composition were observed for both molecular and imaging analyses, and the two analysis methods provided complementary information about bacterial community structure within each leaf developmental stage.Conclusions: Both taxonomic and cell-size trait patterns provided evidence for niche-based contributions to microbial community development on leaves.
How Does Advertising Depend on Competition? Evidence from U.S. Brewing
Authors: Chandra Ambarish , Weinberg Matthew 
Published: January 2018

The relationship between market structure and advertising has been extensively studied, but has generated sharply opposing theoretical predictions, as well as inconclusive empirical findings, likely because of severe endogeneity concerns. We exploit the 2008 merger of Miller and Coors in the U.S. brewing industry to examine how changes in local concentration affect firms’ advertising behavior. Well-established regional preferences over beer brands, and the sharp increase in concentration from the merger, make this an excellent setting to analyze this question. We find a significant positive effect of local market concentration on advertising expenditures: a 100-point increase in the Herfindahl–Hirschmann Index measure of concentration increases advertising per capita by about 5%. Our findings shed light on how and when firms choose to deploy advertising. The online appendix is available at https://doi.org/10.1287/mnsc.2017.2889.

Truth Telling Under Oath

Published: January 2018

Oath taking for senior executives has been promoted as a means to enhance honesty within and toward organizations. Herein we explore whether people who voluntarily sign a solemn truth-telling oath are more committed to sincere behavior when offered the chance to lie. We design an experiment to test how the oath affects truth telling in two contexts: a neutral context replicating the typical experiment in the literature, and a “loaded” context in which we remind subjects that “a lie is a lie.” We consider four payoff configurations, with differential monetary incentives to lie, implemented as within-subjects treatment variables. The results are reinforced by robustness investigations in which each subject made only one lying decision. Our results show that the oath reduces lying, especially in the loaded environment—falsehoods are reduced by 50%. The oath, however, has a weaker effect on lying in the neutral environment. The oath did affect decision times in all instances: the average person takes significantly more time deciding whether to lie under oath.This paper was accepted by Uri Gneezy, behavioral economics.
A Stochastic Programming Model for Casualty Response Planning During Catastrophic Health Events
Authors: Caunhye Aakil M. , Nie Xiaofeng 
Published: January 2018

Catastrophic health events are natural or man-made incidents that create casualties in numbers that overwhelm the response capabilities of healthcare systems. Proper response planning for such events requires community-based surge solutions such as the location of alternative care facilities and ways to improve coordination by considering triage and the movement of self-evacuees. In this paper, we construct a three-stage stochastic programming model to locate alternative care facilities and allocate casualties in response to catastrophic health events. Our model integrates casualty triage and the movement of self-evacuees in a systemic response framework that treats uncertainties involved in such large-scale events as probabilistically distributed scenarios. Solution times being instrumental to the practicality of the model, we propose an algorithm, based on Benders decomposition, to generate good solutions fast. We derive new valid inequalities, which we add to the Benders decomposition master problem to reduce the number of weak feasibility cuts generated. Because our algorithm can also be ineffective if the number of scenarios is large, we propose a two-stage approximation model that attempts to guess good third-stage solutions without third-stage decision variables and constraints. Our model, algorithm, and two-stage approximation are implemented in the case study of an earthquake situation in California based on the realistic ShakeOut Scenario data.

Blue and pink in extracurricular music education. Some differences associated with gender at the beginning of studies
Authors: Cantero Irene Martínez 
Published: January 2018

Several studies have already been carried out to analyse the reasons of why a boy or a girl starts to study music outside school and chooses his or her instrument. These results make it possible to raise some knowledge, one of them about the gender differences that exist in this educational sector which leads to the perpetuation of stereotypes linked to them, thereby limiting the possibilities according to the sex with which they were born. This article presents a research carried out with students in different educational centres in the Region of Murcia and the province of Alicante, with the aim of knowling the influence that gender has on the instruments selected, those of the environment and those that these students prefer. From this perspective, students’ initial motivations towards music and their instrument are also analysed. The results, parallel to other researchs, show important similarities in all of these matters. They also provide data that can be related to the musical environment of this research.
Hacia una epistemología decolonial de la notación musical
Authors: Burcet María Inés 
Published: January 2018

Musical notation appears as a problematic aspect in the debate about the forms of coloniality of knowledge. It is often seen as an instrument of domination because it imposes itself as a mode of representation for music coming from oral tradition, which finds innumerable limitations in the notation for its record. The epistemology of musical notation that is questioned here as hegemonic is that which: (i) limits its possibilities to academic repertoire; (ii) warns about its (in)ability to register other music; (iii) limits and reduces its function to that of a register; (iv) encourages the development of reading skills in particular; and (v) assumes the activity of reading as decoding and writing as codifying with its concomitant pedagogy. This epistemology entails a Eurocentric perspective of musical notation that has colonized music education, naturalizing not only in the fields of musical training, but also in ordinary life. In this article we propose to question that epistemology, providing empirical evidence and arguments that allow us to estimate alternative assumptions for thinking about musical notation as a system of representation, with the consequent decolonial possibilities that this implies.
Continuing Professional Development: Vital airway management skills when treating a pulmonary embolism
Authors: Higginson Ray , Parry Andy , Burrows Paul 
Published: January 2018

Overview A pulmonary embolism (PE) is an occlusion of the pulmonary artery that occurs because of a thrombus originating from a deep vein thrombosis. In this CPD module, we will highlight key steps in performing respiratory assessment of a patient with PE, and outline paramedic treatment and management of this condition. A PE results in ventilation with a reduced perfusion. Early intervention to maintain the airway and facilitate oxygen delivery can reduce PE-associated mortality.
Locked posterior dislocation of the shoulder
Authors: Basal Ozgur , Dincer Recep , Turk Bulent 
Published: January 2018

Locked posterior dislocation of the shoulder is very rare. Seizures and trauma are the most common causes of this injury. There is no current benchmark treatment strategy for these rare cases. This study has shown that reconstruction of the shoulder joint in an anatomical way in acute and chronic cases up to 16 weeks provides good results. The purpose of this study is to evaluate the results of different treatment procedures with outcomes and to compare the results of the same procedures in acute and chronic cases.Cite this article: EFORT Open Rev 2017;3:15–23.

Published: January 2018

AbstractBACKGROUNDThe diagnosis of active tuberculosis (TB) cases primarily relies on methods that detect Mycobacterium tuberculosis (Mtb) bacilli or their DNA in patient samples (e.g., mycobacterial culture and Xpert MTB/RIF assays), but these tests have low clinical sensitivity for patients with paucibacillary TB disease. Our goal was to evaluate the clinical performance of a newly developed assay that can rapidly diagnose active TB cases by direct detection of Mtb-derived antigens in patients' blood samples.METHODSNanoparticle (NanoDisk)-enriched peptides derived from the Mtb virulence factors CFP-10 (10-kDa culture factor protein) and ESAT-6 (6-kDa early secretory antigenic target) were analyzed by high-throughput mass spectrometry (MS). Serum from 294 prospectively enrolled Chinese adults were analyzed with this NanoDisk-MS method to evaluate the performance of direct serum Mtb antigen measurement as a means for rapid diagnosis of active TB cases.RESULTSNanoDisk-MS diagnosed 174 (88.3%) of the study's TB cases, with 95.8% clinical specificity, and with 91.6% and 85.3% clinical sensitivity for culture-positive and culture-negative TB cases, respectively. NanoDisk-MS also exhibited 88% clinical sensitivity for pulmonary and 90% for extrapulmonary TB, exceeding the diagnostic performance of mycobacterial culture for these cases.CONCLUSIONSDirect detection and quantification of serum Mtb antigens by NanoDisk-MS can rapidly and accurately diagnose active TB in adults, independent of disease site or culture status, and outperform Mycobacterium-based TB diagnostics.
The beginning of theatre in Saudi Arabia
Authors: Althaqeel Naif Khalaf 
Published: January 2018

Abstract
Saudi Arabia’s oil potential has attracted attention from international governments since 1973. However, aside from discussions of this aspect of the Saudi economy, there is little information readily available in the international arena regarding its other potentialities, such as its people, society and cultural heritage. Theatre in Saudi Arabia dates to the 1930s, when not only Saudi Arabia but also most of its Arabic neighbours encountered the art form. At present, there are few resources and studies describing Saudi theatre, which limits knowledge and understanding about the dramatic arts in the country. This article, therefore, represents an effort to bridge the gap between Saudi theatre and the international theatrical community, by allowing unique access to this context. To achieve this, the article focuses on the beginnings of Saudi theatre, exploring its origins, the manner in which it began, and the conditions surrounding its emergence.
The respectable courtesan: Malka Pukhraj, music and the postcolonial nation
Authors: Afzal-Khan Fawzia 
Published: January 2018

Abstract
Within the spirit of tracing continuities between an occluded past (Hindu-majority India) with the present-day nation of Muslim Pakistan, this article examines Malka Pukhraj’s memoir, Song Sung True (2003), which weaves a narrative of courtly and classical music and folklore traditions of early twentieth-century Indo-Pakistan in her performative work. As a classically trained female singer of India and Pakistan, Pukhraj enacts a tale of gender, class and ‘respectability politics’ that poses a challenge to traditional norms at one level, while paradoxically working within/even accepting some of these same norms. Her work can be read as a Pakistani-style ‘queer’ performative monologue that allows her to signify a persona as a singer and a woman at a particular historical juncture in India and later in Pakistan. And that resists fitting in to a monolithic definition of any of these constructs.

Rare birds in Slovenia in 2016 – Slovenian Rarities Committee Report
Authors: Hanžel Jurij 
Published: January 2018

Summary
This report by the Slovenian Rarities Committee presents records of rare bird species in Slovenia in 2016, with some addenda for previous years. The numbers in brackets refer to the number of records (first number) and individuals (second number) recorded between 1 Jan 1950 and 31 Dec 2015. Since 1 Jan 2013, submission to the Committee has been required for 37 additional species, 17 of which are regional rarities. Records of these species are not numbered, since records from previous years were not collected by the Committee. Two new species, Scopoli’s Shearwater Calonectris diomedea and Arctic Tern Sterna paradisaea, were added to Category A. Other notable observations were the second record of Lesser Yellowlegs Tringa flavipes, third and fourth records of Pallid Swift Apus pallidus, fifth to seventh records of Long-legged Buzzard Buteo rufinus and the sixth and seventh records of Gannet Morus bassanus. Twelve records of Pallid Harrier Circus macrourus are an all-time annual high. Among Category E species, the Hooded Merganser Lophodytes cucullatus was recorded for the second time. The list of birds recorded in Slovenia (as of 31 Dec 2016) contains 388 species (373 in Category A, 6 in Category B, 9 exclusively in Category C; 4 species are both in Categories A and C). Category D contains 6 species, while Category E contains 38, two of which are classified into Subcategory E*. These two categories are not part of the list.
Review of Middle Spotted Woodpecker Dendrocopos medius distribution in the Karst region (W Slovenia), results of the first systematic census and first recorded breeding of the species in the area
Authors: Cernich Sara , Stanič Domen 
Published: January 2018

Abstract
The Middle Spotted Woodpecker Dendrocopos medius is a highly specialised woodpecker inhabiting mature deciduous forests. The presence of large mature oaks Quercus sp. is a very important factor determining the species' presence and distribution. In Slovenia it is more common in the eastern part, where it inhabits mainly lowland flood-plain oak forests. In other parts of the country it is more localised, as is the case in western Slovenia, where small isolated populations were recently discovered. In this paper we present the currently known observations of Middle Spotted Woodpecker in the Karst region (W Slovenia), the results of the first systematic survey and the first documented breeding of the species in this area. The survey was carried out on the 20 of March 2016 in the wooded hills between the villages of Senožeče and Veliko polje. Using playback method we recorded a total of 8 territorial woodpeckers, confirming our initial expectations about the species' abundance in that area. Breeding was also confirmed in the hills of Senožeče, an active nest-hole was found on 23 Apr 2017. On 18 May 2017 at least 3 juveniles successfully left the nest. Middle Spotted Woodpeckers have recently been observed also in other oak woodlands across the Karst and nearby areas, especially outside the breeding season. These areas include Lipica, Bazovica, the Brkini hills and the Gorica Karst. From summer 2016 onwards several observations of Middle Spotted Woodpeckers have been reported from Lipica, involving up to four different individuals. Repeated sightings in this area and the presence of suitable habitat suggest a probable breeding. The increased number of data in western Slovenia during the last decade might be a consequence of more frequent field visits by ornithologists. Moreover, the presence of the Middle Spotted Woodpecker in this part of the country might be linked to the gradual spreading of forests and the maturing of oak stands already present here. In the above-mentioned areas, further investigations and systematic censuses are therefore needed in the coming springs.
The occurrence of rufous-morph Cuckoo Cuculus canorus females in NE Slovenia
Authors: Bračko Franc 
Published: January 2018

Summary
Between 1982 and 2016, I observed 103 Cuckoos Cuculus canorus in NE Slovenia (3,170 km2). The data were collected randomly, thus only individuals that were seen or ringed are included in the total. Among these, seven females (6.7%) belonged to the rufous morph. The percentage of rufous individuals varies regionally throughout Central Europe.
