Published: August 2017

BackgroundEKG analysis investigating the impact of the ethnicity on cardiac adaptation to exercise has shown a higher presence of abnormalities, including marked repolarization changes, and signs of left ventricular (LV) hypertrophy in black compared to white athletes. Despite the wide availability of EKG analysis, echocardiographic studies on young black and white athletes is lacking in literature.ObjectiveAssess the effect in the secondary LV remodelling to load training in young black players compared to matched white players.Design4 years longitudinal study.SettingSport Medicine outpatients clinic.Patients49 young black soccer players (BP) and 50 white matched soccer players (WP) at the first evaluation: BP=13.3±0.58 and WP=13.9±0.50 years.InterventionsEchocardiography and EKG.Main Outcome MeasurementsInterventricular septum (IVS) and posterior wall (PW) thickness.ResultsNo differences in weight, height, blood pressure in maximal ergometry test.Electrocardiographic repolarization changes were significantly more frequent in BP compared to WP (55% in BP vs 7% of WP). In BP we observed higher level of LV remodelling, consisted in higher LV wall thickness, i.e. higher interventricular septum (IVS) and posterior wall (PW) thickness (IVS: BP=9.99±0.17, WP=9.07±0.14, p<0.001. PW: BP=9.61±0.25, WP=8.85±0.3 mm, p<0.001). At the beginning, BP showed a significantly higher left ventricular remodelling (IVS: BP=9.14±0.6, WP=8.54±0.21 mm, p<0.001. PW: BP=8.98±0.6, WP=8.4±0.26, p<0.001). Afterwards we observed an increase in LV wall thickness and chambers diameters proportionally with the increase in body-size and LV mass. (IVS: BP=10.87±0.23, WP=9.09±0.28 mm, p<0.001. PW: BP=11.69±1.32, WP=9.02±0.24 mm, p<0.001).ConclusionsAlso in young blacks athletes we can find an higher cardiac wall thickness compared to their Caucasian peers. This differences remained after 5 years giving probably reason of the fact that those remodelling events happened in the first years of life by genetic factors.
REGIONAL DIFFERENCES IN BICEPS FEMORIS FASCICLE LENGTH AND PENNATION ANGLE AFTER A SIMULATED SOCCER MATCH

Published: August 2017

BackgroundHamstring Strain Injuries (HSIs) represent 12% of all injuries in soccer players, and their incidence has increased in recent years. Between 53%-84% of HSIs involve the Biceps femoris muscle (BF). Recent studies have shown that soccer players with shorter BF fascicle length (FL) suffer more HSIs and exhibit regional differences in FL and pennation angle (PA) along BF. It is unclear whether there is any regional difference in the degree of change of these parameters after a soccer match.ObjectiveDescribe changes in BF muscle architecture after a simulated soccer match.DesignControlled laboratory study. Pre and Post single session.SettingLaboratory. Amateur Level.ParticipantsSoccer players without acute injuries/illness and no previous lower limb injuries. Data collection is still ongoing. To date, 4 players have been measured and analysed.AssessmentRandomized measurements of muscle architecture parameters at different submaximal contraction intensities, before and after a 45 min. soccer-specific fatigue protocol. Total time 3 hours.Main Outcome MeasuresBiceps femoris absolute and relative changes in PA and FL in 3 different regions of the muscle.Results from this ongoing study imply that relative changes in FL were region-dependent, whereby FL shortening after the protocol was greater in the proximal regions at higher contraction intensities (−2.0% vs 12.3% vs 19.5%), but greater in the distal regions at lower contraction intensities (−8.0% vs 6.7% vs 12.4%).ConclusionsAfter a soccer-specific fatigue protocol, FL and PA of the BF muscle varied regionally and with contraction intensity. Greater FL shortening at proximal regions after a soccer match, especially at higher contraction levels, may be linked to the higher incidence of HSI in these areas, and might help to explain the injury mechanism.
Resilience: Assemblage and Agency at the Echigo-Tsumari Triennale (レジリエンス (可能性): 越後妻有トリエンナーレ における集合体と主体)
Authors: Monsma Brad , モンスマ ブラッド 
Published: August 2017

I will consider the Echigo-Tsumari Art Triennale in Niigata, Japan as an “agentic assemblage” (Jane Bennett) that moves beyond the conception of “land” or “site” as an inert stage for human artistic intentions. The festival functions as the distributed agency of an assemblage including rice fields, river corridors, rural villages and villagers, landslides, heavy snowfall and art objects. This view suggests a fractal causality in which art is conceived within a network of human and nonhuman activity.
As artistic practice, the Triennale makes visible webs of relationships that move beyond notions of site specificity or socio-ecological restoration. From a New Materialist perspective, the festival’s interaction within a mosaic satoyama landscape becomes a visible representation of an evolution of art away from exclusively anthropocentric intentionality. This view suggests deeper readings of the festival’s practice, particular artworks, and of the emphasis on performative food production and consumption – the mutual transformation of material bodies.
私は、人間のアート製作という目的のための単なる舞台として「土地」や「場」を捉えるのではなく、「行為主の集合体」（ベネット）という観点から越後妻有トリエンナーレ（新潟県、日本）について考察する。この トリエンナーレは田圃、河川回路、地方の村と村人、がけ崩れ、大量の降雪とアートを含み込むひとつの集合体の分散的な行為体として機能している。この見方はフラクタルな因果関係を思わせ、その因果関係のなかでアートは人間及び人間以外のモノによる活動のネットワークとして理解される。
アート実践として、このトリエンナーレはサイト・スペシフィック性あるいは社会やエコロジーの回復といった考え方をさらに越えていくような関係性の網目を、眼に見える形にしている。ニュー・マテリアリズムの見地からすれば、このトリエンナーレのモザイク的な里山風景のなかでの相互作用は、過度に人間中心主義的な意図性から離れていくアートの進化を明瞭に表している。このように見ることで、越後妻有トリエンナーレの実践、個々の作品、そしてパフォーマンス的な食物生産と消費の強調−−−−物質的なもの同士の相互の変形−−−−をより深く解釈できるのである。

Ecologies of Land and Sea and the Rural/Urban Divide in Australia: Sugar vs the Reef? and The Yeomans Project (「オーストラリアにおける土地と海の生態学、地方／都市の分割 ：「サトウ対サンゴ？」と「ヨーマン・プロジェクト」」)
Authors: Fisher Laura , フィッシャー ローラ 
Published: August 2017

Australia is a markedly urbanised society, even though many of its most compelling cultural images and narratives are anchored to rural environments and the people and animals that inhabit them. In a country that has always been prone to floods, fires and droughts, there is growing awareness that Australia’s natural resources are under stress due to mining, industrial agriculture, urban development and the effects of climate change. When such issues are debated in the political arena, environmental conservation is regularly pitted against economic advancement in a very crude way, inhibiting cooperation. This essay discusses two art projects that engage meaningfully with the rural/urban divide in Australia: The Yeomans Project and Sugar vs the Reef?. Led by artists Lucas Ihlein, Ian Milliss and Kim Williams, these projects engage in practical and creative ways with rural food production and the individuals responsible for it. Specifically, they investigate innovative farming practices that have great potential to address environmental challenges but are rarely acknowledged in contemporary, city-centric culture. I will argue that by mingling different understandings of aesthetics, utility and ecology, these projects propose productive ways for the disparities between urban and rural Australia to be navigated.
オーストラリアの文化的イメージの多くが、地方の環境およびそこに住む人々や動物に依拠しているのにも関わらず、この国は著しく都市化された社会である。つねに洪水や火事、干ばつを引き起こしやすいオーストラリアにおいて、石炭採掘や産業的農業、都市開発や気候変動の影響によって自然資源に負荷がかかっているということに、多くの人が気付き始めている。このような問題が政治の領域において議論される際、環境保全はいつも粗野な仕方で経済発展と対置され、両者の協働は禁じられている。本稿は、オーストラリアにおける地方／都市の分割に有意義な仕方で関わっている2つのアート・プロジェクトである、「ヨーマン・プロジェクト」と「サトウ対サンゴ？」について論じる。ルーカス・イーライン、イアン・ミリス、キム・ウィリアムズの3人のアーティストによって組織されるこれらのプロジェクトは、実践的かつ創造的な仕方で、地方の食物生産とそれに対して責任を負う人々に関与している。とりわけ、環境の危機に取り組むための大きな可能性を持ちながらも、現代の都市中心の文化においてはめったに注目されない、発明的な農業実践を彼らは調査している。私は、美学、有用性、生態学についての多様な理解を混ぜ合わせながら、これらのプロジェクトを都市的オーストラリアとと地方的オーストラリアとのあいだの不均衡を扱うための生産的な方法として提示する。

Dynamics and Predictability of Downward-Propagating Stratospheric Planetary Waves Observed in March 2007

Abstract
The predictability of a downward-propagating event of stratospheric planetary waves observed in early March 2007 is examined by conducting ensemble forecasts using an AGCM. It is determined that the predictable period of this event is about 7 days. Regression analysis using all members of an ensemble forecast also reveals that the downward propagation is significantly related to an amplifying quasi-stationary planetary-scale anomaly with barotropic structure in polar regions of the upper stratosphere. Moreover, the anomaly is 90° out of phase with the ensemble-mean field. Hence, the upper-stratospheric anomaly determines the subsequent vertical-propagating direction of incoming planetary waves from the troposphere by changing their vertical phase tilt, which depends on its polarity. Furthermore, the regressed anomaly is found to have similar horizontal structure to the pattern of greatest spread among members of the predicted upper-stratospheric height field, and the spread growth rate reaches a maximum prior to the occurrence of the downward propagation. Hence, the authors propose a working hypothesis that the regressed anomaly emerges as a result of the barotropic instability inherent to the upper-stratospheric circulation.
In fact, the stability analysis for basic states constituting the ensemble-mean forecasted upper-stratospheric streamfunction field using a nondivergent barotropic vorticity equation on a sphere supports this hypothesis. Thus, the barotropic instability inherent to the distorted polar vortex in the upper stratosphere forced by incoming planetary waves from the troposphere determines whether the planetary waves are eventually absorbed or emitted downward in the stratosphere.
Buoy Measurements of Wind–Wave Relations during Hurricane Matthew in 2016
Authors: Hsu S. A. , He Yijun , Shen Hui 
Published: August 2017

AbstractStudies suggested that neutral-stability wind speed at 10 m U10 ≥ 9 m s −1 and wave steepness Hs/Lp ≥ 0.020 can be taken as criteria for aerodynamically rough ocean surface and the onset of a wind sea, respectively; here, Hs is the significant wave height, and Lp is the peak wavelength. Based on these criteria, it is found that, for the growing wind seas when the wave steepness increases with time during Hurricane Matthew in 2016 before the arrival of its center, the dimensionless significant wave height and peak period is approximately linearly related, resulting in U10 = 35Hs/Tp; here, Tp is the dominant or peak wave period. This proposed wind–wave relation for aerodynamically rough flow over the wind seas is further verified under Hurricane Ivan and North Sea storm conditions. However, after the passage of Matthew’s center, when the wave steepness was nearly steady, a power-law relation between the dimensionless wave height and its period prevailed with its exponent equal to 1.86 and a very high correlation coefficient of 0.97.
Teachers’ use of dietary recalls for exploratory dialogue in the classroom
Authors: Torres Irene 
Published: August 2017

Objective: This study examines teachers’ adoption and adaptation of 24-hour dietary recall technique for exploratory dialogue in the classroom with students aged 8–12 years. The focus is on the teachers’ use of the information collected through the recall tool to pose open questions, recap, reformulate and elaborate collectively with the students regarding food and nutrition practices. Setting: Three small rural schools in disadvantaged communities of Ecuador. Method: Qualitative participant observations of 24-hour dietary recall sessions, with 49 students aged 8–12, and interviews with seven teachers. Results: Teachers using the recalls as shared objects of learning guided the class through a collaborative process of sensemaking and understanding of their food practices. Based on children’s everyday knowledge and experiences, the teachers helped to search for explanations and solutions by contextualising the discussion while also linking it with specialised nutritional advice. Conclusion: The 24-hour dietary recall aids in organising, connecting and introducing additional information; localising and grounding knowledge; and holding a shared conversation about food and nutrition in the classroom. The tool has potential for teachers to develop instructional skills regarding the discussion of nutrition and health practices within pre-service or in-service training.

Authors: Morrow Sarah A , Classen Sherrilene , Monahan Miriam , Danter Tim , Taylor Robert , Krasniuk Sarah , Rosehart Heather , He Wenqing 
Published: August 2017

Background: Cognitive impairment is common in multiple sclerosis (MS). In other populations, cognitive impairment is known to affect fitness-to-drive. Few studies have focused on fitness-to-drive in MS and no studies have solely focused on the influence of cognitive impairment. Objective: To assess fitness-to-drive in persons with MS with cognitive impairment and low physical disability. Methods: Persons with MS, aged 18–59 years with EDSS ⩽ 4.0, impaired processing speed, and impairment on at least one measure of memory or executive function, were recruited. Cognition was assessed using the Minimal Assessment of Cognitive Function battery. A formal on-road driving assessment was conducted. Chi-square analysis examined the association between the fitness-to-drive (pass/fail) and the neuropsychological test results (normal/impaired). Bayesian statistics predicting failure of the on-road assessment were calculated. Results: Of 36 subjects, eight (22.2%) were unfit to drive. Only the BVMTR-IR, measuring visual-spatial memory, predicted on-road driving assessment failure ( X2 ( df = 1, N = 36) = 3.956; p = 0.047) with a sensitivity of 100%, but low specificity (35.7%) due to false positives (18/25). Conclusion: In persons with MS and impaired processing speed, impairment on the BVMTR-IR should lead clinicians to address fitness-to-drive.

Introduction: Neck enlargement is well described in patients treated with self-expandable endografts for abdominal aortic aneurysms. Double endografting (ie, overlapping of stent grafts) occurs in patients with proximal cuffs or bifurcated to monoiliacal configuration conversions. When the aortic neck of patients receives 2 suprarenal fixation endografts, it may behave differently in terms of radial force and interaction of additional suprarenal stents extending to the visceral aorta. Methods: We performed a retrospective study comparing 2 groups. Group 1 included 18 patients treated with 2 proximal self-expandable endografts. Group 2 included 17 patients treated with 1 self-expandable endograft who were consecutively treated during the period of treatment in group 1. Neck measurements were analyzed in both groups preoperatively and in the last computed tomography scan during follow-up. Suprarenal, interrenal, juxtarenal, and infrarenal (at 5 and 10 mm) diameters, as well as interrenal and infrarenal (5 mm) areas, were measured. Results: There was no significant difference in baseline characteristics, initial neck measurements, and aneurysmal sac evolution including endoleaks between the groups. Both groups showed neck enlargement. Group comparisons of all parameters in posttreatment neck measurements showed no statistical change. Univariate analysis showed oversizing to be significant in interrenal diameter and area and infrarenal at 10 mm diameter; however, 2-way analysis of variance analysis showed that the interaction between oversizing and the number of stent grafts was not significant. Conclusion: Neck enlargement occurs in patients with self-expandable endografts with a tendency to reach the size of the endograft in the long term. Double endografting seems to interact in the same way as simple endografting in the aortic neck. Although the main limitation of our study lies in the small sample size, the presence of an additional “double” stent graft does not appear to result in any differences in aortic neck dilatation when compared to a single stent graft.
PHArmacists’ perspective oN the Take hOme naloxone prograM (The PHANTOM Study)
Authors: Edwards Jenny , Bates Duane , Edwards Brett , Ghosh Sunita , Yarema Mark 
Published: August 2017

Objective: To evaluate pharmacists’ attitudes toward the Take Home Naloxone (THN) program and identify areas that could be improved to support pharmacists’ involvement. Methods: Pharmacists on the Alberta College of Pharmacists’ directory were invited to complete an online survey between July 10 and August 8, 2016. The survey consisted of 19 questions. Descriptive statistics were used to analyze the data. Results: Four hundred seventy pharmacists completed the survey (response rate = 11.2%). A total of 76.8% of respondents strongly agreed or agreed that pharmacists should be screening patients to identify those at risk of opioid overdose. Full-time pharmacists were more likely to agree ( p = 0.02). A total of 79.8% of respondents strongly agreed or agreed that pharmacists should be recommending THN kits. Pharmacists working in large population centres ( p = 0.008) and full-time pharmacists ( p = 0.02) were more likely to agree with this statement. Furthermore, 60.6% of pharmacists were extremely willing or very willing to participate in the THN program. Pharmacists in practice for ≤15 years were more willing to participate in the THN program than pharmacists in practice >15 years ( p = 0.03). The most common perceived barriers to implementation of the THN program were lack of time in pharmacists’ current work environment and education about the program. Conclusions: Overall, pharmacists had positive attitudes toward screening patients to identify those at risk of opioid overdose, recommending THN kits and willingness to participate in the program. Factors that may facilitate increased participation in the program include addressing time issues and improving education about the THN program.
Hip and Groin Injuries in Dancers: A Systematic Review
Authors: Trentacosta Natasha , Sugimoto Dai , Micheli Lyle J. 
Published: August 2017

Context: Injury data on hip and groin injuries vary, and these injuries are often misrepresented or overlooked for more commonly seen injuries, such as those to the foot and ankle. Objective: To provide a systematic review of the injury rates of hip and groin pathology in dancers and look to establish a better understanding of the occurrence of hip and groin injuries in the dancer population. Data Sources: A literature search was performed using PubMed and CINAHL databases for articles published between 2000 and 2016. Study Selection: Inclusion criteria consisted of (1) documentation of the number of hip and/or groin injuries, (2) study population consisting of dancers whose training included some level of ballet, and (3) studies of levels 1 through 3 evidence. Study Design: Systematic review. Level of Evidence: Level 3. Data Extraction: A single reviewer identified studies that met the inclusion criteria. The number of overall injuries, hip/groin injuries, study participants, injured participants, training hours per week, mean age of study group, injury definition, injury reporting method, and study time frame were extracted. Results: Thirteen unique studies were included in the descriptive analysis. Of the 2001 dancers included in this study, 3527 musculoskeletal injuries were seen in 1553 dancers. Of these, 345 injuries were localized to the hip and groin region (overall rate, 17.2%). An incidence rate of 0.09 hip and groin injuries per 1000 dance-hours was seen in the selected cohort studies. Of 462 professional dancers, 128 hip/groin injuries were recorded, for an injury rate of 27.7%. Of the 1539 student dancers, 217 hip/groin injuries were recorded, for an injury rate of 14.1% ( P < 0.01). Conclusion: Data on hip and groin injuries have many limitations. However, these injuries represent an important health issue for dancers of all skill levels, encompassing 17.2% of musculoskeletal injuries seen in dancers. An increasing rate of hip/groin injuries is seen in professional dancers compared with students.
The generalized traveling salesman problem solved with ant algorithms

Published: August 2017

AbstractA well known $$\mathcal{NP}$$
NP
-hard problem called the generalized traveling salesman problem (GTSP) is considered. In GTSP the nodes of a complete undirected graph are partitioned into clusters. The objective is to find a minimum cost tour passing through exactly one node from each cluster. An exact exponential time algorithm and an effective meta-heuristic algorithm for the problem are presented. The meta-heuristic proposed is a modified Ant Colony System (ACS) algorithm called reinforcing Ant Colony System which introduces new correction rules in the ACS algorithm. Computational results are reported for many standard test problems. The proposed algorithm is competitive with the other already proposed heuristics for the GTSP in both solution quality and computational time.
Considerations for pediatric burn sedation and analgesia

Published: August 2017

AbstractBurn patients experience anxiety and pain in the course of their injury, treatment, and recovery. Hence, treatment of anxiety and pain is paramount after burn injury. Children, in particular, pose challenges in anxiety and pain management due to their unique physiologic, psychologic, and anatomic status. Burn injuries further complicate pain management and sedation as such injuries can have effects on medication response and elimination. Burn injuries further complicate pain management and sedation as such injuries can have effects on medication response and elimination. The purpose of this review is to describe the challenges associated with management of anxiety, pain, and sedation in burned children and to describe the different options for treatment of anxiety and pain in burned children.
