Published: November 2015

AbstractSit–stand workstations offer a potential strategy to reduce prolonged occupational sitting. This controlled intervention study examined the effects of an environmental intervention on occupational sedentary time, musculoskeletal comfort and work ability, and the usability of sit–stand workstations in office work via a self‐reported questionnaire. The intervention group (n = 24) used sit–stand workstations during the 6‐month intervention period, and the control group (n = 21) used traditional sitting workstations. The results showed that working at sit–stand workstations can reduce sitting time significantly compared to control workstations (−6.7% vs. 5.0%, p = .019), which is reallocated mostly to standing (r = −0.719, p < .001). Sit–stand workstations improved perceived musculoskeletal comfort in the neck and shoulders (p = .028), as well as work ability (p = .022). The majority of intervention subjects rated sit–stand workstation adjustability as good (83.3%), and 75.0% were satisfied with the workstation. About 41.7% of the intervention participants, who were exclusively female, used the sit–stand function on a daily basis. While the environmental change alone was effective, it is likely that promoting the daily use of sit–stand workstations with counselling would lead to even more substantial positive effects.
Pregabalin Has Analgesic, Ventilatory, and Cognitive Effects in Combination with Remifentanil

Published: November 2015

AbstractAbstract
In a crossover study in 12 volunteers not undergoing surgery, pregabalin, 150 mg twice a day, alone did not affect endtidal carbon dioxide, but it mildly reduced pain report in a cold pressor test. Pregabalin was additive with remifentanil for analgesia and potentiated respiratory depression from remifentanil. The combination of these drugs adversely affected all cognitive tests, whereas each alone did not.

Background
Pregabalin is widely used perioperatively. The authors explored the effects of pregabalin, remifentanil, and their combination on experimental pain, ventilatory, and cognitive function.

Methods
In a randomized, double-blinded crossover study, 12 volunteers received (1) pregabalin + placebo, (2) placebo + remifentanil, (3) pregabalin + remifentanil, and (4) placebo + placebo. Pregabalin 150 mg/placebo was administered twice orally. After baseline, remifentanil/placebo was given as effect-site target-controlled infusion (TCI): 0.6, 1.2, and 2.4 ng/ml. Pain during cold pressor test was scored on visual analog scale (0 to 100 mm). Ventilation was measured by spirometry and cognition tested with Color-Word Interference and Rapid Information Processing tests.

Results
Pain intensity after placebo was (mean) 72 mm (95% CI, 62 to 83). Pregabalin reduced pain score by −10 mm (−14 to −7, P < 0.001). Remifentanil had dose-dependent analgesic effect, reducing pain score by −47 mm (−54 to −39, P < 0.001) on highest TCI level, whereas pregabalin + remifentanil exerted additive effect, reducing pain score by −57 mm (−64 to −50, P < 0.001). Respiratory depression was potentiated by adding pregabalin to remifentanil; end-tidal carbon dioxide was 39.3 mmHg (37.2 to 41.3) with placebo, increased 1.8 mmHg (−0.9 to 4.6, P = 0.4) with pregabalin, 10.1 mmHg (4.9 to 15.4, P < 0.001) with remifentanil, and 16.4 mmHg (11.3 to 21.5, P < 0.001) with pregabalin + remifentanil on highest TCI level. The combination pregabalin + remifentanil, but not either drug alone, adversely affected all cognitive tests.

Conclusions
The combination of pregabalin and remifentanil had additive analgesic effects, pregabalin potentiated remifentanil ventilatory depression, and the combination adversely affected cognition. These results question the clinical benefit of the combination compared with higher doses of opioids.

ABSTRACTIntroduction:Laparoscopic‐assisted ileostomy (LAI) represents a cornerstone for the staged approach to ulcerative colitis (UC). The aim is to determine stoma morbidity in a series of pediatric patients and possibly identify specific risk factors.Methods:All of the patients who underwent LAI for UC between January 2008 and December 2014 were included. The following data were collected: patient demographics, preoperative medical treatment, body mass index (BMI) at surgery, Pediatric UC Index (PUCAI), and stoma‐related complications. In this series of patients, a staged approach has been adopted (subtotal colectomy + ileostomy; restorative proctocolectomy with J‐pouch ileo‐rectal anastomosis + ileostomy; ileostomy closure).Results:Seventy‐two LAIs were fashioned in 37 pediatric patients with UC. Median age at surgery was 12 years (range 5–14.8 years). Boy to girl ratio was 0.85:1. Mortality was zero. Complications occurred after 8 procedures after a median of 31 days postoperatively (range 8–60 days). Those were significantly more frequent in the case of BMI‐z score >−0.51 (deleted in revised manuscript, ie, relatively overweight patients) and in the case of preoperative azathioprine administration. Pediatric UC Index score, sex, number of preoperative medications, and other preoperative parameters did not correlate with the incidence of complications.Conclusions:Our study suggests to keep a prudent behavior in the case of patients with a BMI‐z score >−0.51 and received preoperative azathioprine administration. Parents should be adequately acknowledged on this regard.

ABSTRACTObjectives:The diagnosis of coeliac disease (CD) remains sometimes difficult because the histological criteria are not fully met. The aim of this study was to refine histological diagnostic criteria of CD.Methods:One hundred seventy‐five duodenal bulb D1 (n = 79) and duodenal D2 (n = 96) biopsies of 96 patients with CD (58 girls, mean age 7 years), 135 normal D2 biopsies (69 girls, mean age 12 years), and 64 D2 biopsies of other digestive disorders (DDs) (39 girls, mean age 13 years) obtained from children during a period of 4 years were reviewed.Results:Interobserver agreement was greater for the classification of Corazza‐Villanacci than for Marsh‐Oberhuber (κ = 0.812 vs κ = 0.409, respectively). Between 40 and 70 intraepithelial lymphocytes (IELs) per 100 epithelial cells (ECs), 32% of patients were CD, whereas 50% had other DD. Above 70 IELs per 100 EC, 53% were CD, and only 6% had other DD. In CD, IELs were significantly located above EC nuclei compared with other DD, (12 IELs/100 EC vs 2 IELs/100 EC, respectively). In 21% of CD cases, D2 were normal and the diagnosis could only be made on D1. Finally, 6% of CD cases showed isolated increase of IELs in D1 without architectural modification.Conclusions:D1 allowed diagnosis of CD in 21% of cases and IEL >70 per 100 EC correlated strongly with CD. Between 40 and 70 IELs per 100 EC, CD is very likely but other DD must be considered. Finally, the preferential localisation of IELs above EC nuclei favours CD, and increased IEL in D1 may be the sole abnormality.

Objective
Scorpion stings are a major public health problem in many countries, particularly in pediatrics. Children are more susceptible to severe clinical manifestations of envenomation. The aim of this study is to determine the epidemiological and clinical characteristics of pediatric scorpionism in Hormozgan province of Iran during 2012.

Method
This was a cross-sectional study being conducted during 2010 in Hormozgan, the southern province of Iran. We included 350 patients admitted to emergency unit of the hospitals of 8 cities of Hormozgan with impression of scorpion envenomation. The clinical and epidemiological characteristics as well as the treatment and outcome were recorded.

Results
The prevalence rate of pediatric scorpion stings in the province was 1.8 in 1000 children. The mean age of the patients was 5.75 ± 4.54 (range, 1–18) years. There were 208 (59.5%) boys and 142 (40.5%) girls among the patients. The most common site of sting was sole to knee in 94 (26.8%) followed by hand in 61 (17.4%) and fingers in 47 (13.4%). The most common presenting symptom was vomiting in 236 (67.4%) followed by localized pain in 131 (37.3%), erythema in 120 (34.2%), and edema in 119 (33.9%). The highest and lowest frequency occurred in July (17.7%) and January (3.2%), respectively. Nocturnal envenomations (53.7%) were more common than diurnal (46.3%). Most of scorpionism were mild (83.4%) that all evolved to cure, without any deaths.

Conclusions
The results demonstrate the pediatric scorpionism is a public health problem in Hormozgan province of Iran, and special attention should be paid to prevention and treatment.

Published: November 2015

Introduction:
The bacterium Mycoplasma capricolum subsp. capricolum is known as a pathogen in goats. There have been no reports on a zoonotic potential so far.

Case presentation:
A case of septicaemia and meningoencephalitis in a 62-year-old patient has been associated with infection by M. capricolum subsp. capricolum. No other infectious agent could be detected.

Conclusion:
Although it was impossible to identify the source of infection, coincidental contact with small ruminants or consumption of food products from goats during a tourist trip may have played a role.

Authors: Srinivasacharya D. , Vijay Kumar P. 
Published: November 2015

Purpose
– The purpose of this paper is to study the mixed convection in a nanofluid along an inclined wavy surface embedded in a porous medium.

Design/methodology/approach
– The complex wavy surface is transformed to a smooth surface by employing a coordinate transformation. Using the similarity transformation, the governing equations are transformed into a set of ordinary differential equations and then lineralized using the successive linearization method. The Chebyshev pseudo spectral method is then used to solve linearized differential equations.

Findings
– The effects of Brownian motion parameter, thermophoresis parameter, amplitude of the wavy surface, angle of inclination of the wavy surface for aiding and opposing flows on the non-dimensional velocity, temperature, nanoparticle volume fraction, heat and nanoparticle mass transfer rates are studied and presented graphically.

Originality/value
– This is the first instance in which mixed convection, inclined wavy surface and nanofluid is employed to model fluid flow.

Authors: Hayat Tasawar , Abbasi Fahad Munir , Ahmad Bashir 
Published: November 2015

Purpose– The purpose of this paper is to develop a model for the peristaltic transport of water-based nanofluids and to analyze the impact of nanoparticles on the heat transfer characteristics.Design/methodology/approach– Numerical solutions are obtained using the shooting method.Findings– Pressure gradient decreases whereas the peristaltic pumping region increases with an increase in nanoparticle volume fraction. Silver-water nanofluid experiences greater frictional force at the wall. Temperature of the nanofluid decreases with an increase in nanoparticle volume fraction. Nanoparticles largely increase the heat transfer rate at the boundary. Such increase is maximum when is varied between zero and 0.1.Originality/value– This paper first time develops a model to examine the peristaltic flow of water-based nanofluids. Enhancement of heat transfer in the peristaltic flows due to addition of nanoparticles is investigated.

Authors: Yang Xiao-Hua , Di Chong-Li , He Jun , Zhang Jian , Li Yu-Qi 
Published: November 2015

Purpose
– The purpose of this paper is to assess the water resources vulnerability (WRV) rationally in Haihe River Basin (HRB) using set pair analysis (SPA) theory.

Design/methodology/approach
– An improved intelligent set pair analysis (IISPA) model is established, in which intelligent SPA theory is introduced and the weights are determined by use of the maximum entropy principle and the improved analytic hierarchy process method. The index systems and criteria of WRV assessment in terms of water cycle, socio-economy, and ecological environment are established based on the analysis of sensibility and adaptability.

Findings
– The authors apply IISPA to the WRV assessment of seven administrative divisions in HRB. Results show IISPA can fully take advantage of certain and uncertain information compared with fuzzy assessment and topsis assessment models. For present situation, Shanxi, Shandong, Tianjing, Inner Mongolia, Hebei are higher, Henan and Beijing are the middle vulnerability. But Henan will become worse under climate change scenario II and IV.

Research limitations/implications
– The analysis results may be affected by the limited climate change data.

Practical implications
– It is helpful for further research to the complexity analysis of water resources system.

Social implications
– This paper will have an important impact on water resources sustainable utilization.

Originality/value
– This is the first time to utilize IISPA method to analyze the WRV of seven administrative divisions in HRB. This paper provides an important theoretical support for water resources management.

Authors: Du Guangzhi , Hou Yanren 
Published: November 2015

Purpose
– The purpose of this paper is to propose a parallel partition of unity method to solve the time-dependent convection-diffusion equations.

Design/methodology/approach
– This paper opted for the time-dependent convection-diffusion equations using the finite element method and the partition of unity method.

Findings
– This paper provides one efficient parallel algorithm which reaches the same accuracy as the standard Galerkin method (SGM) but saves a lot of computational time.

Originality/value
– In this paper, a parallel partition of unity method is proposed for the time-dependent convection-diffusion equations. At each time step, the authors only need to solve a series of independent local sub-problems in parallel instead of one global problem.

Effect of curvature and magnetic field on MHD flow of a liquid metal in a curved annular duct
Authors: Bakalis Panteleimon A. , Hatzikonstantinou Pavlos M. 
Published: November 2015

Purpose
– The steady laminar quasi-3D fully developed magnetohydrodynamic (MHD) flow of a liquid metal in a curved annular channel is studied in order to determine the effect of the magnetic field on the velocity distribution. The paper aims to discuss this issue.

Design/methodology/approach
– Due to the fluid motion under the effect of the applied transverse external magnetic field, an additional magnetic field and an electric current density are induced. A hybrid formulation is used for the induced electric current density, implementing for its axial component the Ohm’s law and for its transverse components the Ampere’s law. The suggested formulation (denominated h-formulation) is combined with the extended Continuity Vorticity Pressure numerical variational method for MHD flows.

Findings
– Results are obtained for different values of curvature ratios and Hartmann numbers. It is proved that as the strength of the magnetic field increases, two side regions of velocity jets are formulated in the right and in the left half sides of the inner cylinder in a direction parallel to the external magnetic field. The magnitude of the axial velocity at each region is determined by the balance of the centrifugal and the electromagnetic forces. The results help to better understand the MHD flow in toroidal ducts.

Originality/value
– The results aim to help to a better understanding of the MHD flow in curved ducts.
Information security in supply chains: a management control perspective
Authors: P N Sindhuja , Kunnathur Anand S. 
Published: November 2015

Purpose– This paper aims to discuss the need for management control system for information security management that encapsulates the technical, formal and informal systems. This motivated the conceptualization of supply chain information security from a management controls perspective. Extant literature on information security mostly focused on technical security and managerial nuances in implementing and enforcing technical security through formal policies and quality standards at an organizational level. However, most of the security mechanisms are difficult to differentiate between businesses, and there is no one common platform to resolve the security issues pertaining to varied organizations in the supply chain.Design/methodology/approach– The paper was conceptualized based on the review of literature pertaining to information security domain.Findings– This study analyzed the need and importance of having a higher level of control above the already existing levels so as to cover the inter-organizational context. Also, it is suggested to have a management controls perspective for an all-encompassing coverage to the information security discipline in organizations that are in the global supply chain.Originality/value– This paper have conceptualized the organizational and inter-organizational challenges that need to be addressed in the context of information security management. It would be difficult to contain the issues of information security management with the existing three levels of controls; hence, having a higher level of security control, namely, the management control that can act as an umbrella to the existing domains of security controls was suggested.
User-centred authentication feature framework
Authors: Forget Alain , Chiasson Sonia , Biddle Robert 
Published: November 2015

Purpose
– This paper aims to propose that more useful novel schemes could develop from a more principled examination and application of promising authentication features. Text passwords persist despite several decades of evidence of their security and usability challenges. It seems extremely unlikely that a single scheme will globally replace text passwords, suggesting that a diverse ecosystem of multiple authentication schemes designed for specific environments is needed. Authentication scheme research has thus far proceeded in an unstructured manner.

Design/methodology/approach
– This paper presents the User-Centred Authentication Feature Framework, a conceptual framework that classifies the various features that knowledge-based authentication schemes may support. This framework can used by researchers when designing, comparing and innovating authentication schemes, as well as administrators and users, who can use the framework to identify desirable features in schemes available for selection.

Findings
– This paper illustrates how the framework can be used by demonstrating its applicability to several authentication schemes, and by briefly discussing the development and user testing of two framework-inspired schemes: Persuasive Text Passwords and Cued Gaze-Points.

Originality/value
– This framework is intended to support the increasingly diverse ecosystem of authentication schemes by providing authentication researchers, professionals and users with the increased ability to design, develop and select authentication schemes better suited for particular applications, environments and contexts.

Authors: Han Hyun-Sook , Kim Sungmin , Park Chang Kyu 
Published: November 2015

Purpose
– The purpose of this paper is to develop an automated custom-pattern-making system using the width-height independent grading method for semi-customized clothing.

Design/methodology/approach
– The system reads basic patterns and graded large patterns and calculates the grading ratio of independent horizontal and vertical values on all points in a pattern. The custom pattern is automatically generated by calculating the horizontal and vertical grading amount according to individual body measurements. The system does not follow any complicated alteration rules.

Findings
– The width-height independent grading method can provide custom-pattern fitted primary body circumference and length and helps to quickly produce semi-customized clothing.

Originality/value
– There are few studies on automated custom-pattern-making systems without an alteration rule. This study developed an automatic custom-pattern-making system using the width-height independent grading method.
