Synchrony-city: Sarajevo in five acts and few intervals
Authors: Harrington Selma , Dimitrijevic Branka , Salama Ashraf M.
Published: September 2019

Purpose

The purpose of this paper is to focus on Sarajevo, the capital of Bosnia and Herzegovina, giving a general overview of its urban context through five historical periods, as part of a research study on its modernist architectural heritage.

Design/methodology/approach

Designed to mimic the theatrical process which unfolds through acts and intervals, the paper combines literary, architectural, journalistic and historical sources, to sketch the key periods which characterise the city’s urban morphology.

Findings

The sequence of acts and intervals points to the dramatic historic inter-change of continuities and ruptures, in which the ruptures have often been less studied and understood. This explains the frequent conceptualising of Sarajevo through East–West binary, which synthesises it as a provincial capital from Ottoman and later Habsburg rule, a regional centre within two Yugoslav states and a capital city of a young state of Bosnia and Herzegovina. This highlights the need to study the ruptures as clues to the flow of continuities, in which the care and after care for built environment provide a field of evidence and possibilities for diverse perspectives of examination.

Research limitations/implications

Corroborated by secondary sources, the paper examines the accounts of urban heritage destruction in the 1990s war, as recorded by a writer, an architect and a journalist, and outlines a pattern of unbroken inter-relations between urban and architectural space (tangible) and sense and identity of place (intangible).

Practical implications

This discourse is relevant to the current situation where the city of Sarajevo expands again, in the complexity of a post-conflict society.

Social implications

Challenged by the political divisions and the laissez-faire economy, the public mood and interest is under-represented and has many conflicting voices.

Originality/value

Inspired by Italo Calvino’s Invisible Cities and the accounts from the siege of Sarajevo in the 1990s, this conceptual paper contributes to the formulation of a cross-disciplinary discursive prism through which the fragments of the city and its periods come together or apart, adding, subtracting and changing layers of meaning of the physical space.

Authors: Tian Zhe , Abdollahi Ali , Shariati Mahmoud , Amindoust Atefeh , Arasteh Hossein , Karimipour Arash , Goodarzi Marjan , Bach Quang-Vu
Published: September 2019

Purpose

This paper aims to study the fluid flow and heat transfer through a spiral double-pipe heat exchanger. Nowadays using spiral double-pipe heat exchangers has become popular in different industrial segments due to its complex and spiral structure, which causes an enhancement in heat transfer.

Design/methodology/approach

In these heat exchangers, by converting the fluid motion to the secondary motion, the heat transfer coefficient is greater than that of the straight double-pipe heat exchangers and cause increased heat transfer between fluids.

Findings

The present study, by using the Fluent software and nanofluid heat transfer simulation in a spiral double-tube heat exchanger, investigates the effects of operating parameters including fluid inlet velocity, volume fraction of nanoparticles, type of nanoparticles and fluid inlet temperature on heat transfer efficiency.

Originality/value

After presenting the results derived from the fluid numerical simulation and finding the optimal performance conditions using a genetic algorithm, it was found that water–Al2O3 and water–SiO2 nanofluids are the best choices for the Reynolds numbers ranging from 10,551 to 17,220 and 17,220 to 31,910, respectively.
Numerical investigation of anguilliform locomotion by the SPH method
Authors: Rahmat Amin , Nasiri Hossein , Goodarzi Marjan , Heidaryan Ehsan
Published: September 2019

Purpose

This paper aims to introduce a numerical investigation of aquatic locomotion using the smoothed particle hydrodynamics (SPH) method.

Design/methodology/approach

To model this problem, a simple improved SPH algorithm is presented that can handle complex geometries using updatable dummy particles. The computational code is validated by solving the flow over a two-dimensional cylinder and comparing its drag coefficient for two different Reynolds numbers with those in the literature.

Findings

Additionally, the drag coefficient and vortices created behind the aquatic swimmer are quantitatively and qualitatively compared with available credential data. Afterward, the flow over an aquatic swimmer is simulated for a wide range of Reynolds and Strouhal numbers, as well as for the amplitude envelope. Moreover, comprehensive discussions on drag coefficient and vorticity patterns behind the aquatic are made.

Originality/value

It is found that by increasing both Reynolds and Strouhal numbers separately, the anguilliform motion approaches the self-propulsion condition; however, the vortices show different pattern with these increments.

Authors: Duan Jun-Sheng , Chen Lian
Published: September 2019

Purpose

The purpose of this study is to investigate viscoelastic properties for the constitutive equation in terms of distributed-order derivatives.

Design/methodology/approach

The authors considered the steady oscillatory shear flow between two parallel plates (one is fixed and another oscillates in its own plane), and then examined the effects of different forms of the order-weight functions.

Findings

The constitutive equation in terms of distributed-order derivatives can characterize viscoelastic properties. The order-weight functions can effectively describe viscoelasticity.

Originality/value

Model the viscoelastic constitutive equation in terms of distributed-order derivatives, where order-weight functions can select to respond viscoelastic properties.

The porous media theory applied to radiofrequency catheter ablation
Authors: Iasiello Marcello , Andreozzi Assunta , Bianco Nicola , Vafai Kambiz
Published: September 2019

Purpose

Recently, the porous media theory has been successively proposed for many bioengineering applications. The purpose of this paper is to analyze if the porous media theory can be applied to model radiofrequency (RF) cardiac ablation.

Design/methodology/approach

Blood flow, catheter and tissue are modeled. The latter is further divided into a fluid and a solid phase, and porous media equations are used to model them. The heat source term is modeled using the Laplace equation, and the finite element method is used to solve the governing equations under the appropriate boundary conditions and closure coefficients.

Findings

After validation with available literature data, results are shown for different velocities and applied voltages to understand how these parameters affect temperature fields (and necrotic regions).

Research limitations/implications

The model might require further validation with experiments under different conditions after comparisons with available literature. However, this might not be possible due to the experimental complexity.

Practical implications

The improvement in predictions from the model might help the final user, i.e. the surgeon, who uses cardiac ablation to treat arrhythmia.

Originality/value

This is the first time that the porous media theory is applied to RF cardiac ablation. The robustness of the model, in which many variables are taken into account, makes it suitable to better predict temperature fields, and damaged regions, during RF cardiac ablation treatments.
Assessment of energy performance using bottom-up method
Authors: Djebbar Khadidja El-Bahdja , Salem Souria , Mokhtari Abderrahmane
Published: September 2019

Purpose

The purpose of this paper is to analyze energy performance of the multi-storey buildings built in the city of Tlemcen between 1872 and 2016.

Design/methodology/approach

A diagnosis based on a bottom-up methodology, using statistical techniques and engineering, has been developed and applied. To do this, demand condition analysis was conducted using a data collection survey on a sample of 100 case studies. Physical characteristics of the buildings have been determined through the archetype by period. This serves to define the strengths and weaknesses of buildings as energy consumers.

Findings

The obtained results showed that dwellings built between 1872 and 1920 offer better energy performance with a consumption index close to 130kWh/m2/year and this compared to the five periods considered. For dwellings built between 1974 and 1989, energy consumption is higher with an index approaching 300kWh/m2/year, thus qualifying the buildings of this period as energy intensive.

Originality/value

A database is established to collect physical information on the existing housing stock and thus allow their classification vis-à-vis of the energy label. This study is part of a research project aimed at evaluating and determining optimal measures for energy rehabilitation of multi-family buildings in Tlemcen. Thermal rehabilitation solutions are proposed using thermal simulations, in the following studies, to improve thermal performance of existing buildings. This study constitutes the first step of a roadmap applicable to other cities constituting climatic zones in Algeria. This helps to enrich the Algerian thermal regulation in thermal rehabilitation of existing residential buildings and conception of new ones, in urban areas with a similar climate.
Construction of China’s low-carbon competitiveness evaluation system
Authors: Wang Yongjing , Lan Qingxin , Jiang Feng , Chen Chaofan
Published: September 2019

Purpose

As the contradiction between economic development, resource and environment has become increasingly prominent, low-carbon competitiveness has received worldwide focus. This study aims to examine low-carbon competitiveness in 31 provinces (cities and regions) of China.

Design/methodology/approach

An evaluation index system for low-carbon competitiveness in China has been constructed, which is composed of 25 economic, social, environmental and policy indicators. To study the state of low-carbon competitiveness and resistance to China’ development of low-carbon competitiveness, this study uses a combination of the catastrophe progression model, the spatial autocorrelation model and the barrier method.

Findings

China’ low-carbon competitiveness gradually decreases from coastal to inland areas: the Tibet and Ningxia Hui autonomous regions are the least competitive regions, while the Shandong and Jiangsu provinces are the most competitive areas. The spatial correlation of the 31 provinces’ low-carbon competitiveness is very low and lacks regional cooperation. This study finds that the proportion of a region’ wetland area, the proportion of tertiary industries represented in its GDP and afforestation areas are the main factors in the development of low-carbon competitiveness. China should become the leader of carbon competitiveness by playing the leading role in the Eastern Region, optimizing the industrial structure, improving government supervision and strengthening environmental protection.

Originality/value

The paper provides a quantitative reference for evaluating China’ low-carbon competitiveness, which is beneficial for environmental policymaking. In addition, the evaluation and analysis methods offer relevant implications for developing countries.

Authors: Moro Sérgio , Rita Paulo , Esmerado Joaquim , Oliveira Cristina
Published: September 2019

Purpose

Airbnb Experiences is a new type of service launched by Airbnb in November 2016, where users can offer travellers a wide range of activities. This study devotes attention to analysing customer feedback expressed in online reviews published in Airbnb to evaluate those experiences.

Design/methodology/approach

A total of 1,110 reviews were collected from 12 categories, including 111 experiences, resulting in 10 reviews per experience. First, the sentiment score was computed based on the text of the reviews. Second, 17 quantitative features encompassing user, Airbnb experience and review information were used to model the score through a support vector machine. Third, a sensitivity analysis was performed to extract knowledge on the most relevant features influencing the sentiment score.

Findings

Tourists writing online reviews are not only influenced by their tourist experience but also by their own online experience with the booking and online review platform. The number of reviews made by the user accounted for more than 20 per cent of relevance, while users with more reviews tended to grant more positive reviews.

Originality/value

Current literature is enhanced with a conceptual model grounded on existing studies that assess tourist satisfaction with tour services. Both services online visibility and user characteristics have shown significant importance to tourist satisfaction, adding to the existing body of knowledge.
Evolutionary game of knowledge sharing in master-apprentice pattern of innovative organization
Authors: Wang Ruihua
Published: September 2019

Purpose

Knowledge sharing in a master-apprentice pattern is the process of transferring tacit knowledge from masters to apprentices. In addition, 90 per cent of knowledge required for organizational innovation is tacit knowledge in the master-apprentice pattern. The purpose of this paper is to analyze the evolution of knowledge sharing in master-apprentice pattern and explore the consequences of how to improve the knowledge sharing in the master-apprentice pattern.

Design/methodology/approach

This paper uses asymmetric evolutionary game theory to study the evolutionary track of knowledge sharing in master-apprentice pattern of innovative organizations by analyzing the utility of masters and apprentices during the process of knowledge sharing in master-apprentice pattern of the innovative organization.

Findings

The results reveal that when the masters obtained utility from sharing knowledge is greater than that from hoarding knowledge, and the apprentices obtained utility from studying hard is greater than the costs, the innovative organization can get the largest utility from the knowledge sharing in the mater-apprentice pattern.

Research limitations/implications

The limitation of the research is that this paper mainly studies knowledge sharing among individuals and does not research knowledge sharing between individuals and organizations.

Practical implications

This research has extended the understanding of knowledge sharing in master-apprentice and its evolution path. Also, the obtained findings are conducive to promoting knowledge sharing in master-apprentice and improving human resource management in innovative organizations.

Originality/value

This paper attempts to construct the evolution path of knowledge sharing in master-apprentice pattern, which is a useful exploration of the dynamics of knowledge sharing in master-apprentice pattern and makes up for the shortcomings of the existing research.
Modeling of Islamic consumer behavior and background music regarding ambiguity in the Islamic texts
Authors: Akhavan Kharazian Maryam , Azadfar Vahed
Published: September 2019

Purpose

This study aims to develop a model to analyze the effect of background music on Islamic consumer purchase behavior regarding to ambiguity in the Islamic texts.

Design/methodology/approach

In this experimental design, the population included chain store consumers in Tehran, among whom more than 17,000 consumers were selected during 42 days. ANOVA was used to analyze the collected data.

Findings

Based on the results, playing music in a store could significantly influence the total sales and average purchase value, while no positive role was observed on the number of purchases. Furthermore, dual impression form Islam viewpoints regarding music was observed in the present study as it failed to affect the number of sales in spite of influencing the amount of sales. Individuals affected by music buy more expensive goods, which may indicate that those who buy more luxury goods are less inclined to Islamic views or are inclined to those views which regards playing music as legitimate.

Research limitations/implications

Store managers and marketers in Islamic nation are recommended to play pop music in their store to improve total sales. Managers in islamic nation should play some music when they offer more luxury and less ordinary goods. Although the present study attempted to control potential intervening variables to increase validity, controlling intervening variables is a serious limitation for conducting a field study. Uncontrollable intervening variables established by other media are considered as another limitation in this study.

Originality/value

For the first time, this study sheds some light on how the types of background music influences on the Islamic consumers. The study shows the ambiguity in the islamic texts and the differences in the judgments of religious regarding playing music to muslim consumer.
Theoretical analysis of MHD Carreau liquid over a heated rotating disk under Von-Karman transformations
Authors: Bibi Memoona , Sohail Muhammad , Naz Rahila
Published: September 2019

Purpose

The purpose of this paper is to perform an analytical approximation for the flow of magnetohydrodynamic Carreau fluid with the association of nanoparticles over a rotating disk. The disk is moving with a constant uniform speed. Governing equations are obtained by using these assumptions in the form of partial differential equations with boundary conditions. These coupled, highly nonlinear equations are transformed into a coupled system of ordinary differential equations by engaging similarity transformation in the rotating frame of reference.

Design/methodology/approach

An efficient and reliable scheme, namely optimal homotopy asymptotic method, is used to obtain the solutions of the arising physical problem, which is further analyzed graphically. After computing the solutions of the arising problem, plots of velocities, temperature and concentration are discussed briefly.

Findings

It has been observed that dimensionless velocity reduced due to magnetic effect between the boundary layer and escalating values of the magnetic parameter upsurges the temperature and concentration profiles. Contour plots and numerical results are given for local numbers like skin friction coefficient, Nusselt number and Sherwood number.

Originality/value

The work presented in this manuscript is neither published nor submitted anywhere for the consideration/publications. It is a novel work.
Application of double diffusion theories to Maxwell nanofluid under the appliance of thermal radiation and gyrotactic microorganism
Authors: Sohail Muhammad , Naz Rahila , Raza Rabeeah
Published: September 2019

Purpose

The purpose of this paper is to address the entropy analysis of the 3D flow of Maxwell nanofluid containing gyrotactic microorganism in the presence of homogeneous–heterogeneous reactions with improved heat conduction and mass diffusion models over a stretched surface. Improved models are supported out by utilizing Cattaneo–Christov heat flux and generalized Fick’s law, respectively.

Design/methodology/approach

Governing equations which present the given flow phenomenon are modeled in the form of PDEs by applying boundary layer analysis and then suitable makeovers are engaged to transfigure prevailing partial differential equations into a set of ordinary differential equations. Transformed equations are handled via optimal homotopy analysis process in computational tool Mathematica and also a special case of already published work is substantiated and found to be in excellent settlement.

Findings

The bearing of innumerable convoluted physical parameters on velocity, temperature, concentration, reaction rate, the concentration of motile microorganism and entropy generation are presented and deliberated through graphs. Moreover, the convergence of the homotopic solution is presented in tabular form which confirms the reliability of the proposed scheme. It is perceived that mounting values of the magnetic parameter and Brinkman number boosts the irreversibility analysis and Bejan number diminishes for these parameters. Moreover, the growing values of Prandtl and Schmidt numbers reduce the temperature and concentration fields, respectively.

Practical implications

The work contained in this paper has applications in a different industry.

Originality/value

The work contained in this paper is original work and it is good for the researcher in the field of applied mathematics.
An empirical investigation of how information sharing affects cash flow performance through competitive capability
Authors: Lyngstadaas Hakim
Published: September 2019

Purpose

This paper aims to examine how information sharing affects cash flow performance through the competitive capabilities of low cost or product quality.

Design/methodology/approach

In total, 159 survey responses were collected from Norwegian manufacturing firms in 2018. Structural equation modelling (SEM) was used to analyse the data collected.

Findings

The low-cost competitive capability was found to positively mediate the effect of information sharing on cash flow performance. However, product quality competitive capability did not have a significant mediating effect between information sharing and cash flow performance. Rather, customer satisfaction fully mediated the relationship between product quality, capability and cash flow performance. The empirical results not only support how the competitive capabilities can be developed through information sharing but also illustrate that the competitive capabilities affect cash flow performance through different mediating routes.

Originality/value

While information sharing and competitive capabilities have been studied previously with regard to financial performance, less emphasis has been placed on how customer satisfaction might explain the mediated relationship between product quality, competitive capability and financial performance. In addition, financial performance is measured by the proxy of cash flow. The use of cash flow as a performance measure leads to a more forward-looking financial performance measure. This is especially appropriate for non-listed firms.

Authors: Bueno-Guerrero Alberto
Published: September 2019

Purpose

This paper aims to study the conditions for the hedging portfolio of any contingent claim on bonds to have no bank account part.

Design/methodology/approach

Hedging and Malliavin calculus techniques recently developed under a stochastic string framework are applied.

Findings

A necessary and sufficient condition for the hedging portfolio to have no bank account part is found. This condition is applied to a barrier option, and an example of a contingent claim whose hedging portfolio has a bank account part different from zero is provided.

Originality/value

To the best of the authors’ knowledge, this is the first time that this issue has been addressed in the literature.
What lessons have we learnt about the impact of maternal cigarette smoking from animal models?
Authors: Chan Yik L. , Oliver Brian G. , Chen Hui
Published: September 2019

Maternal first‐ or second‐hand tobacco smoking during pregnancy is still common albeit that the detrimental effects to the unborn child are well known. Maternal tobacco cigarette smoking can affect multiple organ systems in the offspring, rendering them at increased risk of various conditions throughout life (eg. intrauterine underdevelopment, asthma, substance abuse, diabetes). However, this review will only focus on its impact on the brain and the related molecular changes in the offspring based on evidence from animal studies. Although epidemiological studies have identified the associations between maternal cigarette smoke exposure (SE) and brain disorders, animal models can help identify the underlying mechanisms and test interventions. Human studies have found that maternal SE is closely linked to small brain size and changes in brain structure and associated with a high risk of cognitive defects. Animal models suggest that this may be due to increased brain oxidative stress and inflammation during the neonatal period, leading to increased brain cell apoptosis in adulthood. There is a distinct gender bias of such impacts, where male offspring are more affected than females. Female offspring seem to have developed the adaptation by increasing endogenous antioxidant levels. Indeed, animal studies have shown that using antioxidant supplementation during pregnancy can improve neurological outcomes in male offspring, however, the efficacy in humans is yet to be confirmed. Furthermore, some animal studies suggested nicotine as the key player in intrauterine underdevelopment due to maternal SE, while human clinical trials using nicotine replacement therapy do not support this mechanism. This review will discuss the possible reasons.

Effects of interdental cleaning devices in preventing dental caries and periodontal diseases: a scoping review
Authors: Amarasena N , Gnanamanickam ES , Miller J
Published: September 2019

To identify and map existing evidence on the effectiveness of interdental cleaning devices in preventing dental caries and periodontal diseases, a scoping review was carried out by electronically searching PubMed, Scopus and Embase. Studies on interdental cleaning devices, written in English, and published from January 2008 up to April 2019 were included in the review. Of 1860 studies identified, six systematic reviews (SR) were included in the review. One SR each was on flossing, interdental brushes, wood sticks and oral irrigation. Of two SR on multitude of interdental cleaning devices, one assessed comparative efficacy while the other both the individual and comparative efficacy. All reviews had assessed the heterogeneity and the methodological quality of studies included, and performed data extraction and meta‐analysis where appropriate. Evidence ranged from weak to moderate with very low‐ to low‐certainty for the adjunctive benefit of these devices to control plaque and gingivitis. It warrants long‐term studies with sufficient power and those assessing the impact of interdental cleaning on interproximal caries to corroborate such evidence. Available evidence on the efficacy of interdental cleaning devices suggests that dental practitioners recommend patient‐specific interdental cleaning devices that enable patients to achieve a safe and high standard of interdental cleaning.

Published: September 2019

Background

Airway ecology is altered in asthma and chronic obstructive pulmonary disease (COPD). Anti‐microbial interventions might have benefit in subgroups of airway disease. Differences in sputum microbial profiles at acute exacerbation of airways disease are reflected by the γProteobacteria:Firmicutes (γP:F) ratio. We hypothesized that sputum microbiomic clusters exist in stable airways disease, which can be differentiated by the sputum γP:F ratio.

Methods

Sputum samples were collected from 63 subjects with severe asthma and 78 subjects with moderate‐to‐severe COPD in a prospective single centre trial. Microbial profiles were obtained through 16S rRNA gene sequencing. Topological data analysis was used to visualize the data set and cluster analysis performed at genus level. Clinical characteristics and sputum inflammatory mediators were compared across the clusters.

Results

Two ecological clusters were identified across the combined airways disease population. The smaller cluster was predominantly COPD and was characterized by dominance of Haemophilus at genus level (n = 20), high γP:F ratio, increased H influenzae, low diversity measures and increased pro‐inflammatory mediators when compared to the larger Haemophilus‐low cluster (n = 121), in which Streptococcus demonstrated the highest relative abundance at the genus level. Similar clusters were identified within disease groups individually and the γP:F ratio consistently differentiated between clusters.

Conclusion

Cluster analysis by airway ecology of asthma and COPD in stable state identified two subgroups differentiated according to dominance of Haemophilus. The γP:F ratio was able to distinguish the Haemophilus‐high versus Haemophilus‐low subgroups, whether the Haemophilus‐high group might benefit from treatment strategies to modulate the airway ecology warrants further investigation.
Cooking together: The IKEA effect on family vegetable intake
Authors: Radtke Theda , Liszewska Natalia , Horodyska Karolina , Boberska Monika , Schenkel Konstantin , Luszczynska Aleksandra
Published: September 2019

Objective

Based on the idea of the ‘IKEA effect’, assuming that individuals like self‐created objects more than objects created by someone else, this study hypothesizes that parents’ involvement of their children in meal planning and preparation is positively related to vegetable intake, mediated via liking vegetables.

Design

Longitudinal observational study with two time points (10‐month interval).

Method

Nine hundred and twenty‐four parent–child dyads filled out questionnaires measuring involvement, vegetable liking, vegetable intake, and further environmental and food‐related determinants of vegetable intake. On average, parents were M = 36.10 (SD = 5.43) and children (54.3% girls) M = 8.24 (SD = 1.44; range 6–11) years old. Hypotheses were tested with path analyses, accounting for intra‐dyadic associations among respective constructs (e.g., parents’ and children's liking vegetables).

Results

Two direct effects were found: (1) parents’ involvement of their children in cooking activities impacted children's liking of vegetables and vegetable intake, and (2) liking vegetables impacted vegetable intake. The effect of involvement on vegetable intake was mediated via liking vegetables, but only for children and not for parents.

Conclusions

The findings emphasize the importance of parents’ encouragement for involving children in the preparation of healthy meals, as this improves liking of vegetables and, thereby, increases their vegetable intake.

Statement of contribution

What is already known on this subject?

Processes behind the effectiveness of shared cooking activities to increase vegetable intake are unclear.

Previous research suggests the IKEA effect as an explanation.

It assumes a higher consumption of self‐created products due to a higher liking compared to third‐party products.

What does this study add?

First test of the IKEA effect for joint cooking activities under consideration of spillover effects in families.

Affirmation of the IKEA effect was found for children, not for parents.

Interventions should focus on the involvement of children in cooking activities to improve vegetable intake.
Fluorescence in‐situ hybridisation for TP63 rearrangements in T cell lymphomas: single‐site experience of 470 patients and implications for clinical testing
Authors: Peterson Jess F , Pearce Kathryn E , Meyer Reid G , Greipp Patricia T , Knudson Ryan A , Baughn Linda B , Ketterling Rhett P , Feldman Andrew L
Published: September 2019

Aims

The aims of this study were to review our 5‐year experience with clinical FISH testing for TP63 rearrangements using both TP63 break‐apart (BAP) and TBL1XR1/TP63 dual‐fusion (D‐FISH) probes to evaluate the frequency of TP63 rearrangements and the distribution of TBL1XR1 vs. alternate partner loci, and to assess whether both probe sets are necessary in all cases undergoing FISH testing.

Methods and results

A retrospective review of the Mayo Clinic cytogenetic database identified 470 patients evaluated by FISH testing for TP63 rearrangements in formalin‐fixed paraffin‐embedded (FFPE) tissue using both BAP and D‐FISH probes. Of these, 25 (5.3%) had TP63 rearrangements. All samples were being investigated for anaplastic large‐cell lymphoma or other T cell lymphoma subtypes. A TBL1XR1 partner was identified by D‐FISH in 12 (48%) of 25 cases. All cases positive by TBL1XR1/TP63 D‐FISH were also positive by TP63 BAP FISH.

Conclusion

This is the largest series of TP63 rearrangements to date. The frequency of positive results among cases referred to a large reference laboratory for TP63 FISH testing was 5.3%. Approximately half of TP63 rearrangements have a TBL1XR1 partner. TP63 BAP FISH testing is sufficient for up‐front testing of FFPE tissue samples. However, because of the genomic proximity of the TP63 and TBL1XR1 loci, we recommend reflex TBL1XR1/TP63 D‐FISH testing in positive and equivocal cases.
The associations among illness perceptions, resilient coping, and medication adherence in young adult hypertensive black women
Authors: Spikes Telisa , Higgins Melinda , Lewis Tene’ , Dunbar Sandra B.
Published: September 2019

Hypertension, a modifiable risk factor of cardiovascular disease, is largely responsible for the disproportionate morbidity and mortality in black women. Black women 20 years of age and older have a higher prevalence of HTN compared to white women (44% vs 28%). Poor adherence and non‐adherence to hypertensive medications have been strongly indicated as a primary contributor to the early onset of disparity in cardiovascular disease morbidity and mortality experienced by black people. The purpose of this study was to examine medication adherence in black women relative to sociodemographic, clinical, cultural context, psychosocial, cognitive, and behavioral factors. This was a prospective, descriptive cross‐sectional study of N = 85, hypertensive black women, with mean age of 39 ± 5.4 years, 18‐45 years of age. Variables and measures included: sociodemographic characteristics, clinical, adverse social stressors, psychosocial, cognitive‐behavioral factors, and medication adherence. Descriptive statistics, correlations, multivariate logistic regressions, and moderation analysis were tested. 81.2% (n = 69) of the sample was categorized as non‐adherent. SBP was the only clinical covariate associated with HTN medication adherence. HTN illness perceptions, composite score, resilient coping, depressive symptoms, exposure to lifetime gender, and racial stressors, were not associated with HTN medication adherence. Using multivariate logistic regression, decreased SBP and lower scores on the “Consequence” dimension of the HTN illness perception scale were associated with medication adherence (χ2 = 10.53,P = .001). Adherence was associated with both the “Consequence” and “Identity” dimensions of the HTN illness perception scale indicating the need and importance for clinicians to have open and honest communication regarding HTN and its treatment in facilitating adherence.
Optical fluorescence imaging with shortwave infrared light emitter nanomaterials for in vivo cell tracking in regenerative medicine
Authors: Fath‐Bayati Leyla , Vasei Mohammad , Sharif‐Paghaleh Ehsan
Published: September 2019

In vivo tracking and monitoring of adoptive cell transfer has a distinct importance in cell‐based therapy. There are many imaging modalities for in vivo monitoring of biodistribution, viability and effectiveness of transferred cells. Some of these procedures are not applicable in the human body because of low sensitivity and high possibility of tissue damages. Shortwave infrared region (SWIR) imaging is a relatively new technique by which deep biological tissues can be potentially visualized with high resolution at cellular level. Indeed, scanning of the electromagnetic spectrum (beyond 1000 nm) of SWIR has a great potential to increase sensitivity and resolution of in vivo imaging for various human tissues. In this review, molecular imaging modalities used for monitoring of biodistribution and fate of administered cells with focusing on the application of non‐invasive optical imaging at shortwave infrared region are discussed in detail.

Published: September 2019

To describe the clinical features, management and outcomes in patients with fungal keratitis at the Sydney Eye Hospital, Australia, over a 9‐year period to guide appropriate initial therapy. A retrospective case review was conducted. Patients diagnosed with fungal keratitis from 1 January 2009 to 31 December 2017 were identified from hospital coding and pathology databases. Data were extracted from the medical records. A total of 55 episodes from 51 patients were included. Mean age was 60 ± 20 years (range: 19‐91 years), and 33 were male. The fungal species was not identified in two patients. Predisposing factors included ocular surface disease in 17 eyes (32%); corneal disease, 15 (28%); corneal trauma, 12 (23%); and contact lens wear, 13 (24.5%). Fusarium spp. (15, 27%) and Candida parapsilosis (10, 18%) were the most common isolates. The median visual acuity at presentation was 1.3 logMAR (range: 0 to 3) and after treatment 0.7 logMAR (range: −0.02 to 3) (P = .008). Despite medical therapy, most commonly with natamycin and topical and oral voriconazole, surgical intervention was required in 21 eyes (40%); including antifungal injections in 9 (16%); corneal transplantation, 16 (30%); evisceration, 2 (4%); and enucleation, 1 (2%). A poor visual outcome was recorded in 27 of 43 (63%) patients. Fungal keratitis remains a cause of significant ocular morbidity; the majority of patients face a poor outcome despite intense medical and at times surgical treatment. In our setting, fungal keratitis was more commonly associated with corneal or ocular surface disease.

Cytomegalovirus encephalitis is a challenging life‐threatening complication following hematopoietic stem cell transplantation for which medical treatment is usually ineffective or toxic. However, in recent years, adoptive T‐cell therapy has been reported to provide a significant chance of cure for patients with viral infections. Herein, two cases of pediatric patients successfully treated with third‐party donor‐derived virus‐specific T cells for CMV meningoencephalitis are reported.

Nevi are benign melanocytic tumors, and some nevi are considered to develop into malignant melanomas. Most nevi arise in the skin, but nevi occasionally occur in the conjunctiva, esophageal mucosa, or at other sites. Pulmonary melanocytic nevi are extremely rare, and only one case has been reported in the literature. Here, we present a case of pulmonary melanocytic nevus, involving a BRAF gene mutation (V600E), and we discuss the potential significance of this condition as a precursor to pulmonary malignant melanoma.

Demethylation inhibitor (DMI) fungicides are used to control brown rot in stone fruit worldwide. However, their specific mode of action can select resistant isolates of Monilinia fructicola. Monilinia fructicola resistant to DMI fungicides are associated with a fitness cost in the absence of selective pressure, indicating that the sensitive population can be re‐established when discontinuing the fungicide in the field. This work aimed to build up the sensitive population of M. fructicola after discontinuing the use of tebuconazole for successive crop seasons. The sensitivity of M. fructicola to tebuconazole was assessed in four commercial peach orchards in Paraná and São Paulo States from 2012/13 to 2015/16. Different fungicide programmes were used and DMI fungicides were discontinued from 2013/14. The sensitivity of M. fructicola to tebuconazole was assessed by a mycelial growth assay in vitro and by determining the frequency of the G461S mutation in the MfCYP51 gene. The isolates from Paraná had high sensitivity to the fungicide across all seasons and the frequency of the G461S mutation remained below 5%. The isolates from São Paulo were highly resistant in the 2012/13 season; however, there was a gradual decline until 2015/16. In addition, the G461S mutation frequency in Sao Paulo State was about 80% in the 2012/13 season, but reduced until it was completely undetectable in 2015/16. These results provide evidence that resistance can be managed in orchards with high selective pressure to tebuconazole after discontinuing the use of the fungicide for at least 3 years.
Maternal smoking during pregnancy and offspring utilisation of health care services: A population‐based cohort study

Published: September 2019

Background

Maternal smoking during pregnancy (MSDP) has been associated with a wide range of adverse effects on offspring health, such as low birthweight, behavioural disorders, and asthma. The number of women that smoke during pregnancy in Denmark is still high, making it relevant to study the long‐term health outcomes in offspring exposed to maternal smoking in utero.

Objective

We investigated whether exposure to MSDP is associated with more frequent use of health care services during the first 10 years of life.

Methods

This population‐based cohort study included participants enrolled in the Danish National Birth Cohort between 1996 and 2003. Data on MSDP were obtained from two telephone interviews during pregnancy and one interview after pregnancy. The primary outcome was contacts to the health care system. From Danish national registries, we obtained information on number and type of contacts to the general practitioner (GP), and information on the specific types of services provided. Further, we obtained information on hospital admissions, and redemption of prescribed medicine. We fitted negative binomial regression models and Cox proportional hazards regression models to estimate associations. All analyses were adjusted for socio‐economic status, birth year, and various maternal factors.

Results

We studied 83,905 liveborn singletons and found that offspring exposed to maternal smoking in utero had more contacts to the GP in the first 10 years of life with an incidence rate ratio of 1.05, 95% confidence interval [CI] 1.04, 1.06. A higher rate of admission to hospital in 9 out of 20 categories was found, as was a higher rate of being prescribed psychoanaleptics (hazard ratio [HR] 1.41, 95% CI 1.25, 1.60), drugs for obstructive pulmonary disease (HR 1.14, 95% CI 1.14, 1.20), and antibiotics (HR 1.03, 95% CI 1.01, 1.05).

Conclusions

We found that offspring exposed to MSDP had a higher use of health care services than unexposed offspring.

Storage of refrigerated semen is a simple and inexpensive procedure that can facilitate the management and reproduction programmes in aquaculture and allows to store semen for in vitro reproduction, quality analyses, hatchery production support, selective in vitro breeding, disease diagnosis, transportation, cryopreservation and advanced molecular studies. Implementation of semen short‐term storage protocols for threatened or endangered fish represents a useful strategy for preservation of these species. Semen cold storage as technique is a useful strategy for the conservation of fish sperm. Analysing the male broodstock sperm quality during cold storage is a tool to identify the reproductive ability of cultivated fish. Thus, in this review we analysed the most relevant factors that affect sperm quality during cold storage of male broodstock semen as well as its effects on motility, viability, mitochondrial membrane potential, superoxide anion level and DNA fragmentation.

Published: September 2019

Background

The efficacy of preemptive treatment containing rituximab to prevent post‐transplant lymphoproliferative disease (PTLD) in children has not yet been fully elucidated.

Methods

We analyzed 19 pediatric patients who developed high Epstein‐Barr virus (EBV) DNAemia (EBV viral load of greater than 40 000 copies/mL) after allogeneic hematopoietic stem cell transplantation (HSCT) and were preemptively administered rituximab. Rituximab was intravenously injected at a dose of 375 mg/m2 once the EBV viral load was greater than 40 000 copies/mL.

Results

In all 19 patients, EBV DNAemia was eradicated after a median of 9 days (range, 3‐20 days), and PTLD did not occur. One patient had transient fever, and four patients did not fully recover B cell counts after transplantation. We suggested that delayed B cell recovery was caused by chronic graft‐versus‐host disease (GVHD) related drugs, not rituximab administration. And there were no other infection‐related side effects.

Conclusions

In conclusion, preemptive therapy containing rituximab is expected to reduce the incidence of PTLD after HSCT and improve post‐transplantation outcomes in children.
