Published: December 2019

Abstract
Background
A small percentage of patients with foreign body ingestion develop complications, which have a variety of clinical presentations. Less than 1% of cases require surgical intervention. We present a patient with an abdominal wall abscess resulting from a fish bone that pierced the cecum. The patient was treated laparoscopically.

Case presentation
A 55-year-old Japanese man presented to our hospital with a complaint of right lower abdominal pain. A physical examination revealed tenderness, swelling, and redness at the right iliac fossa. Computed tomography showed a low-density area with rim enhancement in his right internal oblique muscle and a hyperdense 20 mm-long pointed object in the wall of the adjacent cecum. Based on the findings we suspected an abdominal wall abscess resulting from a migrating ingested fish bone. He was administered antibiotics as conservative treatment, and the abscess was not seen on subsequent computed tomography.
Two months after the initial treatment, he presented with the same symptoms, and a computed tomography scan showed the foreign body in the same location as before with the same low-density area. We diagnosed the low-density area as recurrence of the abdominal wall abscess. He underwent laparoscopic surgery to remove the foreign body. His appendix, and part of his cecum and the parietal peritoneum that included the foreign body, were resected. He had an uneventful postoperative course, and at 1 year after the surgery, the abdominal wall abscess had not recurred.

Conclusions
An abdominal wall abscess developed in association with the migration of an ingested fish bone. We suggest that a laparoscopic surgical resection of the portion of the bowel that includes the foreign body is a useful option for selected cases.

Published: December 2019

AbstractIn this article, an efficient analytical technique, called Laplace–Adomian decomposition method, is used to obtain the solution of fractional Zakharov– Kuznetsov equations. The fractional derivatives are described in terms of Caputo sense. The solution of the suggested technique is represented in a series form of Adomian components, which is convergent to the exact solution of the given problems. Furthermore, the results of the present method have shown close relations with the exact approaches of the investigated problems. Illustrative examples are discussed, showing the validity of the current method. The attractive and straightforward procedure of the present method suggests that this method can easily be extended for the solutions of other nonlinear fractional-order partial differential equations.

Published: December 2019

Abstract
Background
Porcine Reproductive and Respiratory Syndrome (PRRS) is an endemic swine disease causing significant productive and economic losses. Knowledge of PRRS epidemiology is crucial to develop control strategies against this disease. In that regard, classifying farms according to PRRS virus (PRRSV) shedding and exposure, and understanding key drivers of change in status over time, provides great applied knowledge for developing disease control programs. In most European countries, PRRSV monitoring is performed most frequently at the individual farm level although criteria selected for monitoring varies among different regions and farms. The aim of this study was to implement a systematic monitoring program for PRRSV in Spanish sow farms. Breeding herds were classified according to a standardized PRRSV infection status using sampling programs and terminology currently adopted in the United States (US), which allowed an evaluation of PRRSV epidemiology in a large integrated Spanish group during a one-year study period (February 2017–March 2018).

Results
Fifteen farms achieved a stable PRRSV status after the first 4 consecutive samplings and 20 farms were classified as unstable. One of the farms maintained a stable status throughout the duration of the whole monitoring period.
Among the 20 farms classified as unstable at the beginning of the monitoring protocol, 9 farms (45%) never reached the stable status and 11 farms (55%) reached stable status afterwards during the monitoring study period.
From PRRSV PCR positive pools, there were 47 different PRRSV nucleotide sequences from 24 different farms. More than one PRRSV sequence was obtained from 15 farms. In the farms with more than one sequence detected, we observed recirculation of the same PRRSV field strain in 7 farms and introduction of a different PRRSV strain in 5 farms and both events in 3 farms.

Conclusions
Systematic monitoring for PRRSV in breeding herds established a basis of knowledge of PRRSV epidemiology at the farm level and provided key data to classify farms according to PRRSV exposure and shedding status. These data allow further evaluation of the impact of the PRRSV farm status on production and economic performance in breeding herds and additional investigation of factors related to PRRSV epidemiology.
Self-reported diet management, dietary quality, and blood pressure control in Korean adults with hypertension
Authors: Shim Jee-Seon , Jung Sun Jae , Kim Hyeon Chang 
Published: December 2019

AbstractObjectivesHypertension control is a major public health concern. Daily preventive practices of the affected individual are essential for controlling blood pressure (BP). We investigated the association of diet management practice, dietary quality, and BP control among Korean adults with known hypertension.MethodsWe included 4107 participants aged 40–79 years who reported physician-diagnosed hypertension in the Korea National Health and Nutrition Examination Survey 2013–2016. Dietary management practice was defined by self-report, and dietary intakes were assessed by a 24-h dietary recall. Dietary quality and adherence were evaluated based on the Korean Healthy Eating Index (KHEI) using food and nutrient intakes assessed by a 24-h dietary recall. BP control was defined as systolic/diastolic BP < 140/90 mmHg.ResultsWhile the prevalence of dietary management was higher in women than men, BP control rate was not different by sex. Dietary management practice had no significant association with BP control in both men and women. Only in men, dietary quality was positively associated with BP control (OR: 1.10 per KHEI 10 score increase, 95% CI: 1.00–1.20,p-value = 0.04). Men who had a highly adherent diet seemed to have a higher possibility of BP control, but there was no statistical significance (OR: 1.54, 95% CI: 0.84–2.81,p-value = 0.16).ConclusionsA high-quality diet was positively associated with BP control in Korean men aware of their hypertension. Our findings highlight the beneficial impact of dietary management as a means for achieving blood pressure control.

Published: December 2019

Abstract

Background
The arterial effects of hormone therapy remain controversial. This study tested the effects of transdermal estradiol plus intermittent micronized progesterone (TE + IMP) in healthy perimenopausal and early postmenopausal women on several mechanisms involved in the pathophysiology of arterial disease.

Methods
Healthy perimenopausal and early postmenopausal women, ages 45 to 60 years, were enrolled in this randomized, double-blind, placebo-controlled trial. Women were randomized to receive TE (0.1 mg/day) + IMP (200 mg/day for 12 days) or identical placebo patches and pills for 12 months. Outcomes included: change in stress reactivity composite z-score (combining inflammatory, cortisol, and hemodynamic responses to a standardized psychological laboratory stressor); flow-mediated dilation (FMD) of the brachial artery (an index of vascular endothelial function); baroreflex sensitivity; and metabolic risk (presence of the metabolic syndrome or insulin resistance), all assessed at baseline and at months 6 and 12.

Results
Of 172 women enrolled, those assigned to TE + IMP tended to have higher resting baroreflex sensitivity than those assigned to placebo across the 6- and 12-month visits. Although treatment groups did not differ in terms of the other prespecified outcomes, a significant treatment-by-age interaction was found for FMD and stress reactivity such that an age-related decrease in FMD and increase in stress reactivity were seen among women assigned to placebo but not those assigned to TE + IMP. Women on TE + IMP also had lower resting diastolic blood pressure, lower levels of low-density lipoprotein cholesterol, and higher baroreflex sensitivity during stress testing.

Conclusions
TE + IMP tended to improve cardiac autonomic control and prevented age-related changes in stress reactivity and endothelial function among healthy perimenopausal and early postmenopausal women.

Authors: Lee Sun Y , Cabral Howard J , Aschengrau Ann , Pearce Elizabeth N 
Published: December 2019

Abstract

Context
The effects of maternal subclinical hypothyroidism on pregnancy outcomes are not clear.

Objective
We aimed to assess potential associations between maternal thyrotropin (thyroid-stimulating hormone [TSH]) levels in pregnancy and obstetric and perinatal outcomes.

Design
Retrospective cohort study.

Setting
Tertiary academic medical center.

Patients
Women aged ≥18 years with a singleton gestation and no known thyroid disease seen for prenatal care at Boston Medical Center from January 1, 2003 through May 22, 2014, and their fetuses and infants were included.

Main Outcome Measures
Risk ratios of adverse obstetric and perinatal outcomes.

Results
A total of 8,413 pregnant women (mean age 29.1 years, 15% white, 60% black, 13% Hispanic) and their fetuses and infants (mean gestational age at birth 38.5 weeks, 52% male, mean birth weight 3.2 kg) were included in the analyses. The median (interquartile range) TSH level was 1.06(0.62–1.60) mIU/L, and 130 women (1.6%) had TSH &gt; 4 mIU/L. Maternal TSH levels &gt; 4 mIU/L were associated with increased risks of prematurity (risk ratio [RR] 2.17 [95% confidence interval 1.15–4.07] P = .016) and neonatal respiratory distress syndrome (RDS) (RR 2.83 [95% confidence interval 1.02–7.86] P = .046) compared to TSH levels ≤ 4 mIU/L. Although not statistically significant, TSH levels &gt; 4 mIU/L were also associated with increased RRs for fetal loss, preeclampsia/eclampsia, and low birth weight. TSH levels &gt; 4 mIU/L were not associated with preterm labor, placental abruption, cesarean section, gestational hypertension or diabetes, or neonatal intensive care unit admission.

Conclusion
Maternal serum TSH concentration &gt; 4 mIU/L in pregnancy was associated with approximately 2-fold increased risks of prematurity and RDS in offspring. Elevated TSH was also associated with statistically non-significant increases in the risk of fetal loss, preeclampsia/eclampsia, and low birth weight.
Assessment of inducible clindamycin resistance and Hyper Variable Region (HVR) of mecA gene in clinical staphylococci
Authors: Khan Amir Afzal , Farooq Jahanzaib , Abid Madiha , Zahra Rabaab 
Published: December 2019

Objective: To study the prevalence of inducible clindamycin along with vancomycin and methicillin resistance and assessment of hyper variable region (HVR) of mecA gene among different clinical isolates of Staphylococcus spp.
Methods: A total of 176 clinical isolates of Staphylococci were collected from Pakistan Institute of Medical Sciences (PIMS), Islamabad during 2014-2015. The sample sources were pus, blood, urine, sputum, tracheal secretions and tissue fluids. Bacterial identification was done by colony morphology and biochemical tests. Kirby-Bauer disc-diffusion method was carried out to assess the susceptibility against different antibiotics. Minimal inhibitory concentrations (MICs) were done for vancomycin resistance. Double Disk Diffusion test (D-test) was used to detect the clindamycin inducible resistance. PCR was performed to detect erm(C), mecA and HVR genes.
Results: Clindamycin inducible resistance among Staphylococcal isolates was found to be 7%, whereas in S. aureus it was 4%, and in coagulase negative Staphylococci (CoNS) it was 11%. The highest resistance was observed against fosfomycin, fusidic acid and cefoxitin. Vancomycin resistance was observed in 23 isolates (13%) of Staphylococci. erm(C), mecA and HVR genes were found in 18%, 50% and 42% respectively.
Conclusions: D-test must be performed routinely to avoid clindamycin failure. A high level of resistance against vancomycin in Staphylococcal isolates is a concern for public health.

Comparing employability priorities of emerging and experienced interior designers
Authors: Huber Amy M. , Waxman Lisa K. 
Published: December 2019

Abstract
While design scholars have long explored the design process and its underlining decision-making tactics, few empirical studies have examined other judgements that may also influence design practice, such as the skills and contributions of new hires and their fit with their firms’ management style, culture and values. To probe employability priorities, this study first explored broad-based and discipline-specific literature, accreditation standards, and recent position announcements from interior design practice. Next, in order to define those skills and traits most highly valued in commercial interior design, new quantitative survey data was collected from emerging interior designers, and, in turn, was compared to extant research findings on the hiring priorities of experienced management practitioners within the interior design consultancy industry. Survey responses support earlier findings emphasizing soft skills while contributing to the literature by highlighting differing priorities between experienced interior designers and those whom they are likely to hire (i.e. emerging design professionals). Such differing priorities may have resonance in allied design disciplines, which is discussed with implications for design management hiring practice, emerging design professionals’ employability efforts, and practices of educators aiming to enhance the employability of design graduates.
Can participatory design support the transition into innovative learning environments?
Authors: Bøjer Bodil 
Published: December 2019

Abstract
When changing from traditional classrooms to innovative learning environments it is crucial to include the users of the environment in the design process. However, participatory processes might be limited by contrasting expertise, cultures, priorities or project restrictions, which poses a risk to the alignment of spatial design and pedagogical practices. To meet this challenge, the article proposes a post-design participatory activation process aimed to support the transition into new learning spaces. This is exemplified in an empirical case, where co-design methods and physical design objects have been explored as tools to foster spatial literacy and competencies in a fifth-grade cohort (teachers and students), and potentially match pedagogical practices with spatial affordances. Participatory activation is believed to be an ongoing process because learning environments are not static designs – they keep evolving based on people, pedagogies and practices.
Design Innovation for creative growth: Modelling relational exchange to support and evaluate creative enterprise in the Scottish Highlands and Islands
Authors: Pierre Johnson Michael , McHattie Lynn-Sayers , Champion Katherine 
Published: December 2019

Abstract
This article examines the development and delivery of a Creative Growth Model as part of a programme of Design Innovation activities with creative micro-enterprises and support organizations in the Highlands and Islands region of Scotland. There is a growing body of critique for how creative enterprise is framed, supported and evaluated in relation to economic notions of value and growth that struggle to incorporate the sociocultural interests and activities of sole traders and micro-enterprises. This article presents a Design Innovation approach for identifying situated conceptions of value, modelled as emergent value constellations, based on the diverse interactions and relational exchanges prevalent within the creative enterprise. This research draws predominantly on the work of Design Innovation for New Growth (DING), a two-year AHRC follow-on funded project between 2017 and 2019, which engaged with existing creative expertise in the Highlands and Northern Isles of Scotland to mobilize local practitioners as central drivers of innovation. The article aims to contribute to co-design literature seeking to develop ‘design practices that understand how value is co-produced, […] understood, generated, and employed’ (Whitham et al. 2019: 2) in conjunction with creative enterprises.

Published: December 2019

Background: Peripheral venous access is frequently performed in various health care settings. However, babiesâ€™ veins are smaller and poorly supported by surrounding soft tissue casing further difficulty of insertion compared to adult patientsâ€™vein. Transillumination device is recommended for difficult insertion of peripheral veins. Nursing practice should accommodate with evolving health care advancement, and therefore the nursesâ€™ are required to develop their knowledge and attitude towards new skill and practice.Objectives: To assess the level of nursesâ€™ knowledge and practice regarding the use of transillumination device for establishing venous access.Methods: A descriptive study design that was conducted among a sample of 20 Nurses working at Hail General Hospital, KSA. The study tool included a questionnaire sheet of 2 parts as demographic variables and then knowledge and practice regarding use of transillumination device for establishing venous access. Selected nurses were asked to fill up the questionnaire sheet.Results: The majority 50% of the nurses were under the age group of 31yrs and above. Most of the 95% nurses were bachelorâ€™s degree and only 5% was masterâ€™s degree. The year of experience were majority of nurses 35% had 7-9 yrs. Designation of nurses indicates, almost 50% of the nurses were working as a Charge Nurse, among 45% as staff Nurse and only 5% as Head Nurse.Obviously, 100% of the nurses perform cannulation in first attempt. Before, 65% of the nurses had no awareness of using veinlite. 100% of the nurses used 26G size cannula.Furtherly, 85% assures that they could incorporate transillumination device into practice. The opinion of 65% nurses feel, this device was easy to use.Conclusion: The study says that, most of the 65% NICU nurses has only average and 35% has good knowledge and practice regarding use of transillumination device for establishing venous access. The nurses have interest in practicing transillumination device and seems to be time saving and effective. Suitable interventional packages need to be given periodically for the effectiveness of qualitative nursing service.Â Â
How teachers can guide students towards the increased use of contextualised MALL in target and non-target countries: The case of L2 Chinese adult students
Authors: Ezra Orit , Cohen Anat 
Published: December 2019

Contextualised mobile assisted language learning (MALL) has been greatly discussed (Pegrum, 2014); however, its potential has not been reached in either target or non-target countries, and this calls for teachers’ attention. This study recommended a way for teachers to guide their Chinese second or foreign language students towards increasing their contextualised MALL, by relying on a framework proposed by Cohen and Ezra (2018) and based on the learners’ existing activities.’s contextualised components include real-world and real-life contexts (a measuring index is proposed), as well as device mobility. The study recommended the following: teachers in target and non-target countries should focus differently on generic and dedicated activities; content factors for dedicated activities should be taken into account; teachers should guide students to relate to the real world and real life, including objects and other core activities. The findings may encourage teachers to guide students without worrying about the extra time spent in an overcrowded curriculum.
Measuring emotions during learning: lack of coherence between automated facial emotion recognition and emotional experience
Authors: Hirt Franziska , Werlen Egon , Moser Ivan , Bergamin Per 
Published: December 2019

AbstractMeasuring emotions non-intrusively via affective computing provides a promising source of information for adaptive learning and intelligent tutoring systems. Using non-intrusive, simultaneous measures of emotions, such systems could steadily adapt to students emotional states. One drawback, however, is the lack of evidence on how such modern measures of emotions relate to traditional self-reports. The aim of this study was to compare a prominent area of affective computing, facial emotion recognition, to students’ self-reports of interest, boredom, and valence. We analyzed different types of aggregation of the simultaneous facial emotion recognition estimates and compared them to self-reports after reading a text. Analyses of 103 students revealed no relationship between the aggregated facial emotion recognition estimates of the software FaceReader and self-reports. Irrespective of different types of aggregation of the facial emotion recognition estimates, neither the epistemic emotions (i.e., boredom and interest), nor the estimates of valence predicted the respective self-report measure. We conclude that assumptions on the subjective experience of emotions cannot necessarily be transferred to other emotional components, such as estimated by affective computing. We advise to wait for more comprehensive evidence on thepredictive validityof facial emotion recognition for learning before relying on it in educational practice.
