Investigation of cerebrospinal fluid flow in the cerebral aqueduct using high-resolution phase contrast measurements at 7T MRI
Authors: Markenroth Bloch Karin , Töger Johannes , Ståhlberg Freddy 
Published: November 2017

Background The cerebral aqueduct is a central conduit for cerebrospinal fluid (CSF), and non-invasive quantification of CSF flow in the aqueduct may be an important tool for diagnosis and follow-up of treatment. Magnetic resonance (MR) methods at clinical field strengths are limited by low spatial resolution. Purpose To investigate the feasibility of high-resolution through-plane MR flow measurements (2D-PC) in the cerebral aqueduct at high field strength (7T). Material and Methods 2D-PC measurements in the aqueduct were performed in nine healthy individuals at 7T. Measurement accuracy was determined using a phantom. Aqueduct area, mean velocity, maximum velocity, minimum velocity, net flow, and mean flow were determined using in-plane resolutions 0.8 × 0.8, 0.5 × 0.5, 0.3 × 0.3, and 0.2 × 0.2 mm2. Feasibility criteria were defined based on scan time and spatial and temporal resolution. Results Phantom validation of 2D-PC MR showed good accuracy. In vivo, stroke volume was −8.2 ± 4.4, −4.7 ± 2.8, −6.0 ± 3.8, and −3.7 ± 2.1 µL for 0.8 × 0.8, 0.5 × 0.5, 0.3 × 0.3, and 0.2 × 0.2 mm2, respectively. The scan with 0.3 × 0.3 mm2 resolution fulfilled the feasibility criteria for a wide range of heart rates and aqueduct diameters. Conclusion 7T MR enables non-invasive quantification of CSF flow and velocity in the cerebral aqueduct with high spatial resolution.

Published: November 2017

Background: No studies have focused on the everted type of bursal-sided partial-thickness rotator cuff tears (PTRCTs). Purpose: To evaluate the radiological characteristics, arthroscopic findings, and clinical and structural outcomes after arthroscopic repair of the everted type of bursal-sided PTRCTs. Study Design: Cohort study; Level of evidence, 3. Methods: Two groups of patients with bursal-sided PTRCTs (simple type, 25 shoulders; everted type, 25 shoulders) were enrolled. The mean age was 59.6 years (range, 47-73 years) and 60.8 years (range, 48-72 years) among patients with the simple and everted type, respectively. The mean follow-up period was 2.7 years (range, 2.0-5.1 years). Results: The everted type always exhibited an acromial spur (hat-shaped, 52%; heel-shaped, 48%) and bony changes in the greater tuberosity (bony spur, 52%; sclerotic changes, 48%). Hat-shaped spurs of the acromion were not observed in the simple type. The everted type showed significantly thicker tendon on magnetic resonance imaging (MRI), as the stump was retracted superomedially (mean thickness: 8.1 ± 1.2 mm vs 5.5 ± 1.1 mm for the everted and simple type, respectively). During arthroscopic repair, additional sutures were needed more often for the everted type than for the simple type (64% vs 16%, respectively). After repair, the tendon margin was uneven and ragged in 16% of shoulders with the everted type. Preoperatively, the visual analog scale (VAS) score for pain during motion and range of motion (ROM) were significantly worse in patients with the everted type than in those with the simple type (VAS score, 7.2 vs 5.6, respectively; ROM for forward flexion, 146.8° vs 156.4°, respectively). Postoperatively, no significant differences in the VAS score, ROM, or clinical outcomes were observed between the 2 groups, with no retears on follow-up MRI in either group. Conclusion: The everted type of bursal-sided PTRCTs showed a characteristic hat-shaped acromion, often with bony spurs of the greater tuberosity. On MRI, the tendon stump appeared thickened because of the everted flap. The everted type was more likely to require additional sutures because of an uneven or ragged tendon margin. However, satisfactory clinical and structural outcomes were observed for both the simple and everted types.

Published: November 2017

Objectives: Sepsis-3 recommends using the quick Sequential Organ Failure Assessment (qSOFA) score followed by SOFA score for sepsis evaluation. The SOFA is complex and unfamiliar to most emergency physicians, while qSOFA is insensitive for sepsis screening and may result in missed cases of sepsis. The objective of this study was to devise an easy-to-use simple SOFA score for use in the emergency department (ED). Methods: Retrospective study of ED patients with sepsis with in-hospital mortality as the primary outcome. A simple SOFA score was derived and validated and compared with SOFA and qSOFA. Results: A total of 3297 patients with sepsis were included, and in-hospital mortality was 10.1%. Simple SOFA had a sensitivity and specificity of 88% and 44% in the derivation set and 93% and 44% in the validation set for in-hospital mortality, respectively. The sensitivity and specificity of qSOFA was 38% and 86% and for SOFA was 90% and 50%, respectively. There were 2760 (84%) of 3297 qSOFA-negative (<2) patients. In this group, simple SOFA had a sensitivity and specificity of 86% and 48% in the derivation set and 91% and 48% in the validation set, respectively. Sequential Organ Failure Assessment was 86% sensitive and 57% specific in qSOFA-negative patients. For all encounters, the areas under the receiver–operator characteristic curves (AUROC) were 0.82 for SOFA, 0.78 (derivation) and 0.82 (validation) for simple SOFA, and 0.68 for qSOFA. In qSOFA-negative patients, the AUROCs were 0.80 for SOFA and 0.76 (derivation) and 0.82 (validation) for simple SOFA. Conclusions: Simple SOFA demonstrates similar predictive ability for in-hospital mortality from sepsis compared to SOFA. External validation of these findings is indicated.

Authors: Cojocari Vladimir , Culiuc Vasile , Bzovii Florin , Casian Dumitru , Gutu Eugen 
Published: November 2017

Introduction: Although saphenofemoral junction aneurysms are not so rare, only scarce of the published cases reported thrombosis of the aneurysmal sac and saphenous trunk. Presentation of case: A 65-year-old male with varicose disease, developed acute ascending superficial vein thrombosis of the left greater saphenous vein, involving the 6-cm saphenofemoral junction aneurysm. The patient underwent common femoral vein thrombectomy, aneurysm removal, and greater saphenous vein excision with uneventful postoperative course. Conclusion: Thrombosed giant saphenofemoral junction aneurysms require emergent surgical intervention aimed at preventing potential progression to deep vein thrombosis and pulmonary embolism.
Challenges in the Clinical Application of the American Society of Clinical Oncology Value Framework: A Medicare Cost-Benefit Analysis in Chronic Lymphocytic Leukemia
Authors: Seymour Erlene K. , Schiffer Charles A. , de Souza Jonas A. 
Published: November 2017

Purpose: The ASCO Value Framework calculates the value of cancer therapies. Given costly novel therapeutics for chronic lymphocytic leukemia, we used the framework to compare net health benefit (NHB) and cost within Medicare of all regimens listed in the National Comprehensive Cancer Network (NCCN) guidelines. Methods: The current NCCN guidelines for chronic lymphocytic leukemia were reviewed. All referenced studies were screened, and only randomized controlled prospective trials were included. The revised ASCO Value Framework was used to calculate NHB. Medicare drug pricing was used to calculate the cost of therapies. Results: Forty-nine studies were screened. The following observations were made: only 10 studies (20%) could be evaluated; when comparing regimens studied against the same control arm, ranking NHB scores were comparable to their preference in guidelines; NHB scores varied depending on which variables were used, and there were no clinically validated thresholds for low or high values; treatment-related deaths were not weighted in the toxicity scores; and six of the 10 studies used less potent control arms, ranked as the least-preferred NCCN-recommended regimens. Conclusion: The ASCO Value Framework is an important initial step to quantify value of therapies. Essential limitations include the lack of clinically relevant validated thresholds for NHB scores and lack of incorporation of grade 5 toxicities/treatment-related mortality into its methodology. To optimize its application for clinical practice, we urge investigators/sponsors to incorporate and report the required variables to calculate the NHB of regimens and encourage trials with stronger comparator arms to properly quantify the relative value of therapies.

Published: November 2017

Objective:
To use the patient outcome endpoints overall survival and progression-free survival to evaluate functional parameters derived from dynamic contrast-enhanced CT.

Methods:
69 patients with metastatic renal cell carcinoma had dynamic contrast-enhanced CT scans at baseline and after 5 and 10 weeks of treatment. Blood volume, blood flow and standardized perfusion values were calculated using deconvolution (BVdeconv, BFdeconv and SPVdeconv), blood flow and standardized perfusion values using maximum slope (BFmax and SPVmax) and blood volume and permeability surface area product using the Patlak model (BVpatlak and PS). Histogram data for each were extracted and associated to patient outcomes. Correlations and agreements were also assessed.

Results:
The strongest associations were observed between patient outcome and medians and modes for BVdeconv, BVpatlak and BFdeconv at baseline and during the early ontreatment period (p &lt; 0.05 for all). For the relative changes in median and mode between baseline and weeks 5 and 10, PS seemed to have opposite associations dependent on treatment.
Interobserver correlations were excellent (r ≥ 0.9, p &lt; 0.001) with good agreement for BFdeconv, BFmax, SPVdeconv and SPVmax and moderate to good (0.5 &lt; r &lt; 0.7, p &lt; 0.001) for BVdeconv and BVpatlak. Medians had a better reproducibility than modes.

Conclusion:
Patient outcome was used to identify the best functional imaging parameters in patients with metastatic renal cell carcinoma. Taking patient outcome and reproducibility into account, BVdeconv, BVpatlak and BFdeconv provide the most clinically meaningful information, whereas PS seems to be treatment dependent. Standardization of acquisition protocols and post-processing software is necessary for future clinical utilization.

Advances in knowledge:
Taking patient outcome and reproducibility into account, BVdeconv, BVpatlak and BFdeconv provide the most clinically meaningful information. PS seems to be treatment dependent.

Published: November 2017

Abstract
Implementing an art-appreciation programme enabled a group of 5- and 6-year-old children to explore artists and their artworks and to understand artistic/aesthetic elements through a systematic sequence investigation. This study examines the impact of a sixteen-week art programme based on a visual literacy theory focusing on children’s art appreciation and critical thinking in Korea. Using mixed methods, data were collected through measurement of children’s appreciation and critical thinking ability, interviews with teacher and class observations. Quantitative analysis demonstrated significant effects of the art intervention programme on children’s abilities to appreciate art and artists and think critically about them. Three qualitative themes emerged: (1) deepening understanding of art, (2) experimenting with art, and (3) expressing themselves through art. Suggestions and implications for curriculum and research are provided.
Teachers adopting artists’ pedagogies: Is it really that simple?
Authors: Selkrig Mark 
Published: November 2017

Abstract
Bringing artists into learning sites such as schools has resulted in diverse educational benefits for students. As a consequence a gaze has turned to the pedagogies artists employ, to consider how their strategies might inform the practice of ‘mainstream’ school teachers. With this scrutiny of artists’ pedagogies, the voices of artists involved in this type of work and how they describe what they do has received limited attention. Drawing on data from a research project in Australia, which explored the learning for artists who work in educational settings, I consider the teaching approaches these artists described along with ‘effective pedagogy’ espoused in educational discourse. While acknowledging the good work artists claim they do in educational settings, rather than viewing artist pedagogies as better or competing with teachers’ pedagogies, they are or can be complementary. Both art teachers and artists play important roles in school art programmes.
Next Art Education: Eight theses future art educators should think about
Authors: Meyer Torsten 
Published: November 2017

Abstract
The next art is the art of the Next Society. Sociologist and cultural theorist Dirk Baecker pinpoints the term Next Society to the society based on the computer as the leading media technology. Baecker develops his argument on the assumption that nothing influences societal structures and cultural forms as significantly as the respective dominating media technology. As a result in the long run, the introduction of the computer will impact society as dramatically as the introduction of language, writing and printing press. Next Art Education is the attempt to tie in with this assumption by looking for adequate considerations in the field of art education.
Building communities of practice: Pre-service teachers as content architects
Authors: Shields Sara Scott , Jesup Cindy 
Published: November 2017

Abstract
In this visual essay we map a pedagogical exploration from conception to realization. Informed by scholarship in collaborative learning and inspired by the work of contemporary artist, Annalise Rees, we asked pre-service educators to visualize their instructional strengths and weaknesses through the construction of buildings. We asked our students to act as educational content architects, tasked with building a structure physically and conceptually reliant on collaboration and connection. This visual essay first explores collaborative learning in pre-service education through the lens of communities of practice. Next, the essay introduces the parameters of the assignment, before closing with an overview of student outcomes.
Meaning-Centrism in Roland Barthes’ Structuralism
Authors: Zhang Shuping 
Published: November 2017

Abstract
Meaning and form are two important concepts in philosophy, literature, and other humanities, and discussions on the dialectical relationship between meaning and form have lasted for 2,000 years. Though the importance of meaning was considered, attention, interest, and studies were overwhelmingly focused on form much more than meaning, especially in the popular period of aestheticism, formalism, and structuralism. Henceforth, form retained ultimate supremacy over meaning. Roland Barthes was one of the giants of structuralism and was traditionally regarded as a formalist during his structuralist period (1950s–1967). In fact, Barthes’ semiotic thought was composed of two branches, cultural semiotics and literary semiotics. He valued meaning and the way of meaning-making in his cultural semiotics, and was devoted to exploration of hidden meaning, as well as the relationship between meaning and form. He found three layers of meaning hiding in mass media, i.e. denotation, connotation, and myth, which shape and reshape readers’ ideology, and persuade them to accept the ideology of the middle class. While forms are plentiful, even overflowing, meaning is relatively simple, but meaning is of supreme importance, as it manipulates forms in an implicit way. Consequently, Roland Barthes was really meaning-oriented or meaning-centrist in his cultural semiotic thought.
Spread of Eragrostis albensis (Poaceae) and Dittrichia graveolens (Asteraceae) in the southern Poland
Authors: Wróbel Anna , Nobis Marcin 
Published: November 2017

Abstract
New localities of Eragrostis albensis H. Scholz and Dittrichia graveolens (L.) Greuter have been found in the southern Poland. The former taxon is currently considered a kenophyte (epecophyte and holoagriophyte) in the country. It occurs on sandy alluvia along Vistula, Oder and San River Valleys as well as on anthropogenic sites mainly in the eastern and south-eastern Poland. The latter species is a recent newcomer regarded as an ephemerophyte, which so far has been reported from only one locality in Śląskie Province. In 2017 we discovered 16 new localities of E. albensis and five of D. graveolens on the territory of the southern Poland. Populations of both species consisted of few to several dozen individuals which grew within anthropogenic habitats, mainly roadsides. Distribution maps of both species in the southern Poland were presented.
Structure of avian communities in lowland coniferous forests in Opole Silesia (SSW Poland)
Authors: Kopij Grzegorz 
Published: November 2017

Abstract
In Poland, forests comprise 31% of the total surface area, while the lowland coniferous forests comprise 51% of 94 000 km2 afforested areas. The line transect method was employed in 2002 and 2004 to estimate population densities and dominance of all bird species breeding in a selected fragment of such forest (eight transects with 165 sections and 77.7 km in total length). In total, 54 breeding bird species were recorded. The numbers varied between 37 and 44 on the particular transect. The number of breeding pairs per 10 ha varied on each transect from 41.0 to 93.6 (x=64.8; SD=102.22). Shannon’s diversity index varied between 1.2 and 1.4 on particular transects, while Simpson’s diversity index varied between 0.7 and 0.9. Also Pieleau’s evenness index varied slightly between 0.05 and 0.07. In overall, the differences between densities of breeding species on 8 transects were not statistically significant. The Chaffinch Fringilla coelebs was by far the most numerous bird species, recorded as eudominant in all eight transects and present in all 165 sections. The second to the Chaffinch was the Chiffchaff Phylloscopus collybita; also recorded in all sections and as a dominant in all transects. Three other species, namely the Blackbird Turdus merula, Willow Warbler Phylloscopus trochilus and Blackcap Sylvia atricapilla were recorded each one in more than 90% sections (N=165), and on particular transects their dominance varied between 4 and 11%. Residents comprised 57.5% of all breeding pairs. Short-distance migrants were almost twice more common than long-distance migrants. Insectivores were by far the most numerous feeding guild represented 88.9% of all breeding pairs. Overall density, cumulative dominance, diversity and evenness were unexpectedly very similar in this study (managed forest) and in natural primeval lowland coniferous forests of Białowieża.

This article places the book in the context of the poet’s Scandinavian reception since her own time and today. The travelling book forms an appropriate illustration of the spread of women’s writing, as studied by the EU-funded project
Redefining the Road for the Industry
Authors: Amsel Tuvya T. 
Published: November 2017

Abstract
The polygraph is an instrument that detects, monitors, and records physiological responses that are allegedly of psychological origin and attributed to deception. Hence the human mind and its complex psychology are the core of the detected physical responses. However, the polygraph industry has almost entirely overlooked psychological issues in its training and publishing. The industry focuses its attention and interest on various technical aspects of the test such as e.g. scoring, rather than concentrating on what is most important, i.e. the examinee’s psychology, as it is responsible for almost the entire test result. The paper extensively explains the importance of examinee psychology and its influence on test outcome, points to the shortfalls in training and publication activity of the industry, and discusses the result and impact of the industry’s approach.
Interprofessionality in the model courses of study for healthcare and nursing professions in North Rhine-Westphalia, Germany / Interprofessionalität in den Modellstudiengängen der Pflege- und Gesundheitsberufe in Nordrhein-Westfalen
Authors: Hallwaß Anke , Hollweg Wibke 
Published: November 2017

Abstract
Interprofessional cooperation is attributed a special significance in overcoming new challenges in the health system. For the educational system, this means the development of innovative teaching and learning formats that encourages interaction between students from different professions within healthcare. In Germany in the state of North Rhine-Westphalia (NRW), eleven model courses of study for healthcare and nursing professions have been developed and evaluated. Evaluation reports do not tell whether social interaction between students of different professions is promoted. The following study investigates to what extent interprofessionality is incorporated into the model courses of study for healthcare and nursing professions in NRW and to what extent the courses of study include social interaction between students of different professions. In addition, an analysis is made as to what extent structural and organisational conditions and the course management influence the (further) development of the courses with a view to interprofessionality. Structured expert interviews have been carried out with those responsible for the courses of study, for a total of seven model courses. These have then been evaluated using qualitative content analysis. The promotion of interprofessional expertise is incorporated into all model study courses that were considered and is generally governed by international standards. Six of the seven courses of study offer social interaction between students of different professions. Valuable hints for interprofessional education at colleges for health could be achieved.
