Increasing Nursing Students’ Knowledge of Autism Spectrum Disorder by Using a Standardized Patient
Authors: McIntosh Constance E. , Thomas Cynthia M. , Wilczynski Susan , McIntosh David E. 
Published: November 2017

Abstract
Nursing students participated in a simulation using a standardized patient role-playing an adolescent with autism spectrum disorder (ASD). The researchers used student feedback to develop and improve a simulation aimed at increasing learner skills and knowledge for treating ASD patients. Students indicated that the standardized patient provided realism not obtained when using static manikins or high-fidelity simulators. Students strongly agreed or agreed that classroom instruction prior to the simulation was important to increasing their knowledge of ASD. Overall, the simulation provided students an opportunity to practice and develop their clinical skills in caring for patients with ASD.
Nursing Humanities: Teaching for a Sense of Salience
Authors: Lim Fidelindo , Marsaglia Matthew John 
Published: November 2017

Abstract
Reports have indicated that nursing programs in the United States are not generally effective in teaching nursing science, natural science, the social sciences, and the humanities. The value of the lifelong study of humanities for nurses is the invitation for contemplation on the human experience so we can make informed moral, spiritual, and intellectual sense of the world. In essence, when we understand, we become more empathetic. This article adds to the call for teaching for a sense of salience in nursing through the meaningful synthesis of humanities in baccalaureate education.
Transforming Nursing Education: A Call for a Conceptual Approach
Authors: Feller Frederica 
Published: November 2017

Abstract
In an effort to meet the changing landscape of the health care system and the explosion of nursing knowledge, the Institute of Medicine and the Robert Wood Johnston Foundation have summoned nursing academia to partner on curriculum development with an emphasis on the professional socialization of the new nurse. As health care continues to change, the education of nurses must also evolve to meet these changes. Curriculum transformation is needed at nearly every aspect of health care. This policy statement will explore these challenges and the transformation in nursing education required to meet them.
Can Clinical Simulation Increase Confidence Levels in Performing Postpartum Care in a Diverse Group of Baccalaureate Nursing Students?
Authors: Germain Michelle , O’Leary-Kelley Colleen , Goyal Deepika , Anand Sulekha 
Published: November 2017

Abstract
Nursing duties are often sensitive in nature and may contribute to feelings of inadequacy for students, especially when providing postpartum care. Our study assessed confidence levels among 61 junior baccalaureate nursing students before and after a simulation workshop with a follow-up survey administered after completion of two full clinical days on a postpartum unit. The four-hour simulation included stations for breast, fundus, and lochia exam skills. Overall confidence and confidence in performing patient assessments were significantly increased at postsimulation and follow-up (p < .001), demonstrating the efficacy of the simulation.

ABSTRACT

Introduction: It was observed that women with aneurysmal subarachnoid hemorrhage (aSAH) tended to have earlier menses than a typical 21- to 28-day cycle. The goal was to determine whether there is an association between aSAH and early onset of menses. Methods: All cases of aSAH in women aged 18 to 55 years who were admitted to our facility’s neuroscience intensive care unit from June 1, 2011, to June 30, 2012, were reviewed. The electronic healthcare record for each of these patients was examined for documentation of menses onset, computed tomography of the head, brain aneurysm characteristics, modified Fisher score and Glasgow Coma Scale on admission, presence/absence of vasospasm, medical/surgical history, and use of medications that affect the menstrual cycle. The mean onset of menses in this study population was compared with the mean of 21 to 28 days with the 1-sample t test. Results: During the study period, 103 patients with subarachnoid hemorrhage were admitted. Sixty-one were women, and 15 were aged 18 to 55 years. Nine of the 15 (60%) had documentation of menses occurring during their initial week of hospitalization; 1 patient had documentation of menses on hospital day 12. There is a significant difference when the mean onset of menses in our patient population is compared with the approximate normal menstrual cycle of 21 to 28 days (P < .01). Conclusion: Early onset of menses or abnormal uterine bleeding after SAH may occur in women with aSAH and typically within the first 7 to 10 days after intracranial aneurysm rupture. The physiologic cause of early onset of menses after aSAH, whether primary or secondary, remains unknown.
Patient, Injury, Assessment, and Treatment Characteristics and Return-to-Play Timelines After Sport-Related Concussion: An Investigation from the Athletic Training Practice-Based Research Network
Authors: Valovich McLeod Tamara C. , Kostishak Nicholas , Anderson Barton E. , Welch Bacon Cailee E. , Lam Kenneth C. 
Published: November 2017

Objectives:
To describe the patient, injury, assessment and treatment characteristics, as well as return-to-play timelines and clinical findings at discharge for adolescent patients after sport-related concussion.

Design:
Retrospective analysis of electronic medical records.

Setting:
Athletic training facilities of secondary school members of the Athletic Training Practice-Based Research Network (AT-PBRN).

Patients:
In total, 1886 patient records were reviewed. [1204 (63.8%) male, 682 (36.2%) female, age = 15.3 ± 1.9 years, height = 169.5 ± 13.5 cm, mass = 70.3 ± 17.0 kg]. Patients were diagnosed with a concussion by an athletic trainer or team/directing physician.

Interventions:
None.

Main Outcome Measures:
Descriptive analysis of patient, injury, assessment, treatment, and participation status characteristics, as well as discharge information.

Results:
Injury demographic forms were completed for 1886 concussion cases. A concussion-specific evaluation form was completed for 55.9% (n = 1054) of cases. Treatment documentation was completed on 829 patients (44.0% of initial documented cases). Discharge forms were completed for 750 patients (40.0% of initial documented cases). Most cases were coded as 850.9-Concussion (85.5%, n = 642) and occurred during an in-season game (49.4%, n = 308). Time lost from competition was 24.9 ± 39.9 days.

Conclusions:
Most concussion cases documented in this study were not on-field emergencies, as indicated by their normal clinical examinations and the lack of immediate referral to an emergency department. However, certain aspects of the clinical examination were often not assessed during the initial evaluation. These findings describe concussion assessment and recovery in adolescents and reinforce the need for a standardized approach to concussion assessment and appropriate documentation.

Published: November 2017

Background
Data on the association of Helicobacter pylori infection and BMI are conflicting. The fact that both H. pylori infection and BMI are associated with low socioeconomic status (SES) makes this relationship difficult to characterize.

Materials and methods
We aimed to evaluate the association between BMI and H. pylori infection after adjusting for multiple covariates. We analyzed a cohort of 235 107 individuals aged 18 years or older, who performed a 13C urease breath test (13C-UBT), from 2007 to 2014. Data on BMI, age, sex, SES, ethnicity, and medications were extracted from a nationwide population-based database. BMIs were classified according to the WHO recommendations: underweight (<18.5 kg/m2), normal weight (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2), obese class I (30–34.9 kg/m2), and obese class II or more (>35 kg/m2).

Study results
The positivity rate for H. pylori among underweight, normal weight, overweight, and obese class I and class II or more was 55.6, 58.5, 63.0, 64.5, and 65.5%, respectively (P<0.001, P
linear trend 0.007). The association between BMI and H. pylori infection was significant across all SES, sex, ethnicity, and age categories. After adjusting for age, sex, ethnicity, and SES, being overweight and obese class I and class II or more were associated significantly with H. pylori positivity: odds ratio 1.13 [95% confidence interval (CI): 1.11–1.15], 1.14 (95% CI: 1.11–1.17), and 1.15 (95% CI: 1.11–1.19), respectively, P value less than 0.001 for all.

Conclusion
Among individuals who were referred to a 13C-UBT by primary care physician, after adjusting for multiple covariates including SES, we found a positive association between H. pylori infection and an increased BMI.
Fluorine-18-fluorodeoxyglucose uptake of bone marrow on PET/CT can predict prognosis in patients with colorectal cancer after curative surgical resection
Authors: Lee Jeong Won , Baek Moo-Jun , Ahn Tae Sung , Lee Sang Mi 
Published: November 2017

Objective
This study investigated the relationship of fluorine-18-fluorodeoxyglucose (18F-FDG) uptake of bone marrow (BM) on PET/computed tomography (PET/CT) with clinicopathologic factors and survival in patients with colorectal cancer.

Patients and methods
The study retrospectively included 226 patients with colorectal cancer who underwent 18F-FDG PET/CT for staging workup and treated with curative surgical resection. The maximum 18F-FDG uptake of primary cancer (T
max) and mean 18F-FDG uptake of BM [BM standardized uptake value (SUV)] were derived from PET/CT images. The relationships between BM SUV and clinicopathologic factors and prognostic value of BM SUV for predicting recurrence-free survival (RFS) were assessed.

Results
Patients with T3–T4 stage and hepatic metastases had significantly higher values of BM SUV than those with T1–T2 stage and no distant metastases (P<0.05). BM SUV showed significant positive correlation with T
max, tumor size, serum C-reactive protein level, white blood cell count, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio (P<0.05). Univariate survival analysis revealed that N stage, M stage, tumor involvement of resection margin, lymphatic invasion, and BM SUV were significant predictors for RFS (P<0.05), whereas T
max failed to show significance. In multivariate analysis, N stage (P=0.012 for N1 stage and P=0.020 for N2 stage), tumor involvement of resection margin (P=0.009), and BM SUV (P=0.005) were significantly associated with RFS.

Conclusion
Increased BM SUV was observed in patients with advanced stage and increased serum inflammatory markers. BM SUV was an independent predictor for RFS in colorectal cancer.

Authors: Stocker Daniel , Manoliu Andrei , Becker Anton S. , Barth Borna K. , Nanz Daniel , Klarhöfer Markus , Donati Olivio F. 
Published: November 2017

Purpose
The aim of this study was to compare qualitative and quantitative image quality and geometric distortion of 4 magnetic resonance diffusion-weighted imaging (DWI) sequences of the prostate using comparable imaging parameters and similar acquisition times.

Methods and Materials
Axial T2-weighted turbo spin echo images and axial DWI echo-planar imaging (EPI) sequences, including single-shot spin-echo (ss-EPI), readout-segmented multishot (rs-EPI), selective excitation–reduced field of view (sTX-EPI), and prototype single-shot technique applying slice-specific shimming (iShim-EPI) sequences, were acquired at 3 T in 10 healthy volunteers (mean age, 26.1 ± 3.8 years; body mass index, 23.2 ± 3.0 kg/m2). Two radiologists, blinded to the type of DWI, independently rated DWIs on a 5-point Likert scale regarding subjective image quality features (resolution, demarcation of prostate capsule, zonal anatomy). Interreader agreement was assessed using the intraclass correlation coefficient. Signal-to-noise ratio (SNR) and apparent diffusion coefficient (ADC) values were assessed separately in the peripheral and transitional zone. For the analysis of geometric distortion, the diameter of the prostate from left to right and from anterior to posterior was measured at the level of the verumontanum on b-1000 DWIs and on T2-weighted turbo spin echo images. Differences were compared using the Wilcoxon rank sum test for qualitative parameters, analysis of variance, and Friedman test for quantitative parameters. A P value of less than 0.05 was considered significant, with correction for multiple comparisons.

Results
Interreader agreement was good to excellent (intraclass correlation coefficient, 0.71–0.79) for all qualitative features. Subjective image quality regarding “resolution” was significantly better for ss-EPI than rs-EPI (mean Likert score, 4.25 vs 3.8; P = 0.031) and sTX-EPI (4.25 vs 3.3; P = 0.046) and for iShim-EPI as compared with rs-EPI (4.4 vs 3.8; P = 0.031) and sTX-EPI (4.4 vs 3.3; P = 0.047). There was no significant difference regarding capsule demarcation and zonal anatomy. Signal-to-noise ratio was significantly higher in iShim-EPI than sTX-EPI (SNR ± standard deviation [SD], 28.13 ± 8.21 vs 14.96 ± 2.4; P = 0.015). The ADC values were lower for the peripheral zone in the sTX-EPI than in the ss-EPI (ADC ± SD, 1002.94 ± 83.51 vs 1165.05 ± 115.64; P = 0.013) and the rs-EPI (1002.94 ± 83.51 vs 1244.40 ± 89.95; P = 0.0012) and in the transitional zone in the sTX-EPI compared with the rs-EPI (874.50 ± 200.72 vs 1261.47 ± 179.23; P = 0.0021). There were no statistically significant differences in geometric distortion between all DWI sequences.

Conclusions
Single-shot spin-echo EPI and iShim-EPI showed a tendency toward superior image quality and SNR compared with rs-EPI and sTX-EPI with no significant differences in geometric distortion.

Published: November 2017

BACKGROUND
The American Association for the Surgery of Trauma (AAST) anatomic severity grading system for adhesive small bowel obstruction (ASBO) was validated at a single institution. We aimed to externally validate the AAST ASBO grading system using the Eastern Association for the Surgery of Trauma multi-institutional small bowel obstruction prospective observational study.

METHODS
Adults (age ≥ 18) with (ASBO) were included. Baseline demographics, physiologic parameters (heart rate, blood pressure, respiratory rate), laboratory tests (lactate, hemoglobin, creatinine, leukocytosis), imaging findings, operative details, length of stay, and Clavien-Dindo complications were collected. The AAST ASBO grades were assigned by two independent reviewers based on imaging findings. Kappa statistic, univariate, and multivariable analyses were performed.

RESULTS
There were 635 patients with a mean (±SD) age of 61 ± 17.8 years, 51% female, and mean body mass index was 27.5 ± 8.1. The AAST ASBO grades were: grade I (n = 386, 60.5%), grade II (n = 135, 21.2%), grade III (n = 59, 9.2%), grade IV (n = 55, 8.6%). Initial management included: nonoperative (n = 385; 61%), laparotomy (n = 200, 31.3%), laparoscopy (n = 13, 2.0%), and laparoscopy converted to laparotomy (n = 37, 5.8%). An increased median [IQR] AAST ASBO grade was associated with need for conversion to an open procedure (2 [1–3] vs. 3 [2–4], p = 0.008), small bowel resection (2 [2–2] vs. 3 [2–4], p < 0.0001), postoperative temporary abdominal closure (2 [2–3] vs. 3 [3–4], p < 0.0001), and stoma creation (2 [2–3] vs. 3 [2–4], p < 0.0001). Increasing AAST grade was associated with increased anatomic severity noted on imaging findings, longer duration of stay, need for intensive care, increased rate of complication, and higher Clavien-Dindo complication grade.

CONCLUSION
The AAST ASBO severity grading system has predictive validity for important clinical outcomes and allows for standardization across institutions, providers, and future research focused on optimizing preoperative diagnosis and management algorithms.

Amsterdam house price ripple effects in The Netherlands
Authors: Teye Alfred Larm , Knoppel Michel , de Haan Jan , Elsinga Marja G. 
Published: November 2017

Purpose
This paper aims to examine the existence of the ripple effect from Amsterdam to the housing markets of other regions in The Netherlands. It identifies which regional housing markets are influenced by house price movements in Amsterdam.

Design/methodology/approach
The paper considers the ripple effect as a lead-lag effect and a long-run convergence between the Amsterdam and regional house prices. Using the real house prices for second-hand owner-occupied dwellings from 1995q1 to 2016q2, the paper adopts the Toda–Yamamoto Granger Causality approach to study the lead-lag effects. It uses the autoregressive distributed lags (ARDL)-Bounds cointegration techniques to examine the long-run convergence between the regional and the Amsterdam house prices. The paper controls for house price fundamentals to eliminate possible confounding effects of common shocks.

Findings
The cumulative evidence suggests that Amsterdam house prices have influence on (or ripple to) all the Dutch regions, except one. In particular, the Granger Causality test concludes that a lead-lag effect of house prices exists from Amsterdam to all the regions, apart from Zeeland. The cointegration test shows evidence of a long-convergence between Amsterdam house prices and six regions: Friesland, Groningen, Limburg, Overijssel, Utrecht and Zuid-Holland.

Research limitations/implications
The paper adopts an econometric approach to examine the Amsterdam ripple effect. More sophisticated economic models that consider the asymmetric properties of house prices and the patterns of interregional socio-economic activities into the modelling approach are recommended for further investigation.

Originality/value
This paper focuses on The Netherlands for which the ripple effect has not yet been researched to the authors’ knowledge. Given the substantial wealth effects associated with house price changes that may shape economic activity through consumption, evidence for ripples may be helpful to policy makers for uncovering trends that have implications for the entire economy. Moreover, the analysis controls for common house price fundamentals which most previous papers ignored.
Coopetition among nascent craft breweries: a value chain analysis
Authors: Flanagan David J. , Lepisto Douglas A. , Ofstein Laurel F. 
Published: November 2017

Purpose
The purpose of this paper is to employ an inductive approach to explore how small, nascent, firms in the craft brewing industry use cooperative behaviours with direct competitors to achieve their goals.

Design/methodology/approach
Data were gathered from interviews with the founders of seven small, newly established, craft brewers in a Midwestern city in the USA for this exploratory study. Data analysis followed the general tenants of inductive coding. Porter’s value chain model was used as a framework to organise and conceptualise the coopetitive behaviour uncovered.

Findings
The firms engage in cooperative behaviours with their direct competitors in areas such as process technology development, procurement, inbound logistics and marketing. A particularly interesting and common collaborative activity was breweries recommending/promoting competing breweries to their own customers.

Practical implications
This study provides clear examples of how relationship building with competitors could be advantageous and help small, nascent firms overcome the liabilities of newness and smallness.

Originality/value
Research on coopetition has called for a greater understanding of the nature of cooperative behaviours in small firms, start-ups and firms outside of high-technology industries. Moreover, research has called for finer-grained approaches to conceptualising coopetition. This paper fills these gaps and shows how Porter’s value chain is a useful tool for organising the types of collaborative behaviours that can be part of coopetition. The findings enhance understanding and facilitate future research by illustrating a broad array of cooperative activities that occur between direct competitors.
And then he threatened to kill himself: nightmare viva stories as opportunities for learning
Authors: Sikes Pat 
Published: November 2017

Purpose
In the UK and countries following similar systems of doctoral assessment, there is little research-based evidence about what goes on in vivas. However, “doctoral assessment ‘horror stories’”, abound. The purpose of this paper is to report a study focussing on difficult doctoral examining experiences and argue that sharing such stories can provide a useful basis for examiner and supervisor education.

Design/methodology/approach
The study took a narrative auto/biographical approach.

Findings
The stories participants told show that doctoral examining is relational, emotional and ethical work and that viva outcomes are strongly influenced by subjectivities. There was felt to be a need to share stories of difficulties in order to bring them into the open with a view to prompting transformational change.

Research limitations/implications
Participants were self-selecting and all worked at the same institution.

Originality/value
There are few accounts of examiners’ experiences of the viva.
