Authors: Xu Hewei , Chen Zhengsen , Shen Baixin , Wei Zhongqing 
Published: July 2020

Abstract

Introduction:
Primary bladder mucosa-associated lymphoid tissue (MALT) lymphoma is a rare tumor. To date, the PubMed database contains only 39 English articles covering 63 cases of primary bladder MALT lymphoma. Herein, we report a case of this disease and review the current literature.

Patient concerns:
A 77-year-old woman presented with frequent urination, urinary urgency, and dysuria for 3 years. In the past 3 years, the patient's symptoms recurred and progressively worsened, and she was admitted to the hospital.

Diagnosis:
A histopathological examination revealed the bladder mass as a tumor with high proliferation of atypical B-lymphocytes. Immunohistochemistry showed positive results for CD20, PAX-5, Ki-67, BCL-2, and CD21 and negative results for CD10, MUM1, TDT, and cyclin D1. These data supported the diagnosis of primary bladder MALT lymphoma.

Interventions:
A transurethral resection of bladder tumor was performed to treat the disease.

Outcomes:
The patient was alive and healthy at the 15-month follow-up.

Conclusion:
Primary bladder MALT lymphoma is a rare disease and can be easily missed or misdiagnosed before achieving a histological confirmation. Surgery may be the best choice for both diagnosis and treatment.

Abstract

Introduction:
Abundant myxoid stroma rarely occurs in urothelial carcinomas (UCs). We report an 83-year-old woman with UC of the urinary bladder with abundant myxoid stroma. We summarized the clinicopathological features, immunophenotype, diagnosis, and differential diagnosis of this type of bladder cancer, in order to improve the understanding of surgeons and pathologists.

Patient concerns:
An 83-year-old female presented with hematuria and frequent micturition, without odynuria, hypogastralgia, or fever.

Diagnosis:
The computed tomography scan demonstrated extensive tumors in the anterior wall of the bladder and a soft tissue shadow anterior to the sacrum. Cystoscopy showed massive wide-based tumors located on the anterior and lateral walls of the bladder, with no tumor involving the bladder neck. Multiple punch biopsies were performed, the histologic evaluation of which revealed a poorly differentiated invasive UCs with myxoid stroma.

Interventions:
The patient underwent a laparoscopic radical cystectomy and cutaneous ureterostomy.

Outcomes:
The patient discharged without any complications. Histologic evaluation revealed an invasive UC; the most prominent feature was an abundant myxoid stroma that covered approximately 80% of the lesion and the tumor cells were arranged in cords, small nests, or a sheet-like structure. Immunohistochemically, the tumor cells were positive for CK19, CK20, VEGF, EGFR, p63, 34βE12, MUC1, GATA3, uroplakin3, and TopII (rate = 15%), while the Ki-67 proliferation index was 10%. The myxoid stroma in the mesenchyme stained positively with AB-PAS and colloidal iron, and some tumor cells stained positive for colloidal iron. Considering the histologic, histochemical, and immunohistochemical findings, a diagnosis of UC with abundant myxoid stroma was made. After surgery, the regular follow-up was continued in clinic, and there was no recurrence for 2 years.

Conclusion:
Morbidity associated with UC with abundant myxoid stroma is very low. The diagnosis mainly depends on histopathological and immunohistochemical findings.

Authors: Phillips Emma C. , Smith Samantha E. , Hamilton Ailsa L. , Kerins Joanne , Clarke Benjamin , Tallentire Victoria R. 
Published: July 2020

Introduction
Nontechnical skills (NTS) have been acknowledged to be important for medical students and can be linked to improved clinical performance. However, existing tools to evaluate these within a simulated setting address only a limited number of NTS. The Medical Students' Nontechnical Skills (Medi-StuNTS) behavioral marker system (BMS) outlines 5 categories of NTS for medical students. This study aimed to seek evidence for completeness and content validity to refine the BMS and to ascertain which NTS are essential for medical students.

Methods
We asked 128 workshop participants if they felt there were any missing or irrelevant items in Medi-StuNTS system. A subject matter expert panel (n = 10) rated how essential they considered each item in the BMS. An Item-Content Validity Index was calculated for each skill element and the Scale-Content Validity Index was calculated as a measure of content validity of the full system.

Results
Of the workshop participants, 78.9% felt that there were no missing items and 93% felt that there were no irrelevant items. Potentially missing items highlighted were as follows: “working in a hierarchy,” “leadership,” “awareness of the emotional state of other team members,” and “nonverbal communication.” Fourteen of 16 skill elements achieved the recommended level for content validity (Item-Content Validity Index ≥ 0.78), and the Scale-Content Validity Index was higher than the acceptable level (≥0.8).

Conclusions
Evidence for completeness and content validity of Medi-StuNTS has been demonstrated. There is a far wider range of NTS that seem to be essential for medical students than those assessed by tools developed before Medi-StuNTS. Medi-StuNTS provides comprehensive cover of the essential NTS required by medical students, with specific reference to the skill categories “self-awareness” and “escalating care,” which do not feature in other tools for assessing NTS in this group.
Women Surgeons’ Perspectives on System-level Strategies to Address Interpersonal Workplace Conflict
Authors: Lindquist Kerry M. , Vitous C. Ann , Dossett Lesly A. , Jagsi Reshma , Telem Dana A. 
Published: July 2020

Objective:
We sought to gain a comprehensive understanding of the current methods for conflict resolution and the ways in which women surgeons would prefer workplace conflicts to be adjudicated.

Summary of Background Data:
Interprofessional workplace conflicts are poorly studied, particularly for women in surgery. These conflicts may negatively impact surgical team dynamic and be detrimental to patient safety. Moreover, workplace conflicts and their management are a proposed driver of decreased professional satisfaction and achievement. How women surgeons experience workplace conflicts and how these are managed remains unexplored.

Methods:
We conducted 30 semi-structured interviews with women surgeons across the United States who had experienced workplace conflict that resulted in action by a nonphysician. Surgeons were diverse with respect to demographics, specialty, and institutional settings. Through thematic analysis using NVivo, we analyzed and reported patterns within the data.

Results:
Although the majority of women asserted resilience in how they engage with these situations, many also cited ways in which these events could better be adjudicated. Recommendations included (1) more direct conflict resolution, (2) more transparency in reporting processes, (3) greater opportunity to address complaints, (4) explicit policies for events that repeatedly result in workplace conflict, and (5) divorcing interpersonal complaints from patient safety reporting mechanisms.

Conclusion:
This study motivates and informs best practices around adjudication of workplace conflict to help protect women surgeons and nonclinicians. Going forward, best practices should include more objective criteria for how conflicts are adjudicated. Continued efforts at an institutional level are needed to help mitigate inequities against women surgeons.

AbstractThe explosively expanding COVID-19 pandemic urges the development of safe, efficacious and fast-acting vaccines to quench the unrestrained spread of SARS-CoV-2. Several promising vaccine platforms, developed in recent years, are leveraged for a rapid emergency response to COVID-191. We employed the live-attenuated yellow fever 17D (YF17D) vaccine as a vector to express the prefusion form of the SARS-CoV-2 Spike antigen. In mice, the vaccine candidate, tentatively named YF-S0, induces high levels of SARS-CoV-2 neutralizing antibodies and a favorable Th1 cell-mediated immune response. In a stringent hamster SARS-CoV-2 challenge model2, vaccine candidate YF-S0 prevents infection with SARS-CoV-2. Moreover, a single dose confers protection from lung disease in most vaccinated animals even within 10 days. These results warrant further development of YF-S0 as a potent SARS-CoV-2 vaccine candidate.
Winning and losing at the same time
Authors: McKay Patrick F. 
Published: July 2020

PurposeThe purpose of the paper is to summarize the author’s negative experiences with police. The author seeks to enlighten readers to the differential experiences of blacks and whites in police interactions.Design/methodology/approachThe paper is an essay that details the author’s negative experiences with police, while living in a mid-sized Midwestern city.Research limitations/implicationsThe key research implication of the paper is that whites and blacks often have qualitatively different experiences with the police in local communities. While black professionals may be experiencing professional success at work, they may also grapple with racial slights and harassment that undermine their overall physical and psychological wellbeing.Practical implicationsPractically, this paper highlights the needs for police departments to train police on unconscious biases that lead to potential violence against black people. Prospective police officers should be screened on their racial attitudes and ideology to ensure they are equipped to police a broad array of citizens.Social implicationsSocially, the paper underscores the unique experiences of black people with police compared to their white counterparts. To reduce cultural mistrust among blacks against whites, the latter must show empathy and understanding when blacks report instances of racial harassment and mistreatment. Also, whites who witness racial harassment perpetrated by their families, friends, and people in general, should speak out against such practices.Originality/valueThe author thinks the paper is original in that it chronicles his unique, negative experiences with police as a black man in America. The author provides a theoretical background to understand the recent uptick in police violence against blacks and provide helpful tips for moving forward to improve intergroup relations.
Determinants of non-farm enterprise diversification in rural Ethiopia
Authors: Tshabalala Precious Makhosazana , Sidique Shaufique Fahmi 
Published: July 2020

Purpose
This study aims to analyze the factors that determine non-farm enterprise diversification among farm households in Ethiopia. It extends the analysis by examining enterprises and using pooled data, which has the capacity to generate more accurate outcomes. The existing empirical evidence has focused on all non-farm activities, based on single period, single region data. Much of the existing empirical evidence is based on small-scale and location-specific sample surveys that do not demonstrate the characteristics of aggregate populations.

Design/methodology/approach
The empirical analysis was conducted using a quantitative method. To cater to the censoring nature of participating in non-farm enterprise activities, a panel data double-hurdle model is used to a representative sample of 3,594 Ethiopian rural households.

Findings
The study finds that the age of household head, household size, distance to the market, social capital and access to credit, are determinants for owning one or more non-farm enterprises. The level of income from these enterprises is then determined by the age and education level of the household head, household size, agricultural equipment, distance to markets and access to credit.

Practical implications
This study brings to light factors that influence households to participate in non-farm enterprises and the determining factors for the income level.

Originality/value
Non-farm activities are an important source of household income and a driver of development. This paper provides empirical evidence on factors that determine enterprise ownership using panel data.

Published: July 2020

PurposeEnormous numbers of people suffer from the effects of disasters and humanitarian crises in Africa, including medical and healthcare emergencies. International response to the 2014–2016 Ebola pandemic in West Africa and COVID 19 pandemic vividly demonstrates the need for efficient and effective logistics and supply chain systems in bringing succor to impacted and vulnerable communities. This paper critically reviews the academic literature on logistics models for sourcing, delivery and distribution of medical and healthcare products for humanitarian emergencies in Africa from 1990 to 2018. The paper suggests areas for further research and proposes an effective logistics model useful for international and national humanitarian organizations as well as public health authorities in Africa and developing areas.Design/methodology/approachThe viewpoint paper draws upon a structured comprehensive and critical review of the academic literature on logistics and supply chain management and a qualitative analysis of the literature in 13 leading academic databases covering over 5,550 articles.FindingsThe paper finds significant gaps in the body of logistics and supply chain management research on practical deployable logistics models for sourcing, delivery, and distribution of medical and healthcare products for humanitarian emergencies. The paper suggests a model worthy of consideration by humanitarian and disaster response stakeholders as well as public health authorities in developing countries.Research limitations/implicationsThis is a critical literature review paper based on a comprehensive literature research and analysis for the period from 1990 to 2018 from which a viewpoint is formed.Social implicationsThis paper advocates for further research on appropriate models of logistics for the sourcing, delivery and distribution of medical and healthcare products to enhance the basic human rights and dignity of vulnerable people in developing countries.Originality/valueThe paper contributes directly to policy on logistics, humanitarian aid, disaster management, public health and health security policy in the developing world including Africa.
All to play for: LEGO® SERIOUS PLAY® and its impact on team cohesion, collaboration and psychological safety in organisational settings using a coaching approach
Authors: Wheeler Stephanie , Passmore Jonathan , Gold Richard 
Published: July 2020

PurposeCollaboration and psychological safety are key factors to effective teams. LEGO® SERIOUS PLAY® (LSP) has emerged over the past decade as a development tool used in both educational and workplace settings for a range of purposes. In this study, the authors sought to investigate the impact of the experience of participating in a LSP away-day on the collaboration and psychological safety of the participants.Design/methodology/approachIn this study the subjective experience of participants of LSP workshop awaydays using a coaching approach were examined through interpretative phenomenological analysis. Members of two teams were invited to participate in team awaydays and approximately six weeks later, they were invited to share their reflections on the experience and its impact on team relationships and team performance.FindingsThe interviews revealed that participants' felt experience of engaging with LSP was positive, created closer bonds within the team and a better understanding of each other and the challenges which the team were facing. Participants reported a tangible change in the way they are collaborating and engaging not only just with fellow participants but also with other colleagues.Originality/valueThe experience of the participants in this study supports the view that LSP can have a positive role to play in developing psychological safety and collaboration in organisational teams and that there was a lasting impact on group norms which was sustained after the event.
Understanding electronic and face-to-face word-of-mouth influencers: an emerging market perspective
Authors: Oraedu Chukwunonso , Izogo Ernest Emeka , Nnabuko Justie , Ogba Ike-Elechi 
Published: July 2020

Purpose
This paper aims to advance knowledge on the influencers of positive electronic and face-to-face word-of-mouth (WOM) behaviour by examining an interrelationship model of relationship quality (RQ) components and antecedents in the telecommunication service setting.

Design/methodology/approach
A survey design was used to generate data from informants and was analysed using the partial least square structural equation modelling technique.

Findings
Findings indicate that service quality and relationship value have positive effect on trust and satisfaction, while service communication is positively related to trust but not satisfaction. Both trust and satisfaction have positive effect on face-to-face word-of-mouth (fWOM) and electronic word-of-mouth (eWOM). Additionally, relationship value directly influences fWOM but not eWOM, while service quality did not directly influence either mode of WOM behaviour.

Research limitations/implications
The study was conducted in a single service setting, and thus, outcomes cannot be generalised. Further, the authors limited the study of electronic WOM to only Facebook, WhatsApp and Twitter media. As such, caution should be applied in generalising the research findings across contexts.

Practical implications
This paper provides a guide on how telecom service managers can develop and manage their relationship network. Specifically, it demonstrates how business referrals can be generated and harnessed to build customer retention from different relationship building strategies. The study suggests that service providers that deliver quality services, engineer superior value and provide reliable information are better placed to develop resounding relationships with customers and consequently get them to engage in positive referrals.

Originality/value
This study is unique because it investigates the antecedents of WOM from an inter-relational perspective. By simultaneously examining the direct effects of RQ, and its antecedents on both fWOM and eWOM in a single model, the authors illustrate the antecedents and outcomes of RQ in a distinctive way.
Dynamic Cost Inefficiency of the European Union Meat Processing Firms
Authors: Kapelko Magdalena , Oude Lansink Alfons 
Published: July 2020

AbstractWe apply dynamic data envelopment analysis (DEA) to estimate dynamic cost inefficiency for a sample of European Union (EU) large meat processing firms over the period 2005–2012 and decompose this into the contributions of technical and allocative inefficiency. The estimation of dynamic inefficiencies controls for adjustment costs associated with firms’ investments. We further contribute by measuring dynamic cost inefficiencies and their components with regard to own region group (managerial inefficiencies) and the gap between the pooled frontier and the region‐specific frontier (programme inefficiencies). Results show that technical inefficiency tends to be the largest component of cost inefficiency when both conducting the analysis for the EU as a whole and estimating a region‐specific frontier. Results suggest significant differences in cost, technical, and allocative inefficiencies between meat processing firms in eastern, western and southern EU countries. We also find that the gaps between the pooled and region‐specific frontiers tend to be small to negligible, which suggests that the main source of pooled inefficiencies are shortcomings in managerial practices rather than differences in region‐specific conditions.
Could bacterial associations determine the success of weevil species?
Authors: Morera‐Margarit Pilar , Pope Tom W. , Mitchell Carolyn , Karley Alison J. 
Published: July 2020

AbstractThe weevil superfamily Curculionoidea is the largest insect group and so the largest animal group on earth. This taxon includes species which represent an important threat to many economically important crops and, therefore, pose a risk to agriculture and food security. Insect–bacteria associations have been recognised to provide the insect host with many benefits, such as ensuring the acquisition of essential nutrients or protecting the host from natural enemies. The role of bacteria associations within the weevil superfamily remains nonetheless understudied in comparison with other insect taxa. This review draws together existing knowledge on the influence of bacteria associated with weevils known to be agricultural pest species. The implications of these weevil–bacterial associations in determining pest status and their relevance to targeted pest management interventions are discussed. Specific consideration is given to the role of bacteria in cuticle formation, flight activity, reproduction manipulation and adaptation to different environments and food sources.
