Surgically Treated Carpal Tunnel Syndrome and Ulnar Nerve Entrapment at the Elbow in Different Occupations and their Effect on Surgical Outcome
Authors: Linde Filippa , Rydberg Mattias , Zimmerman Malin 
Published: May 2022

Objective
We investigated whether certain occupations were over-represented among surgically treated carpal tunnel syndrome and ulnar entrapment at the elbow, and if manual occupation affected surgical outcome.

Methods
We included 9030 patients operated for CTS and 1269 for UNE registered in the Swedish National Quality Register for Hand Surgery (HAKIR) 2010–2016. Occupational data was retrieved from Statistics Sweden. Outcome was assessed using the QuickDASH questionnaire.

Results
In patients operated for CTS, there were more assistant nurses, attendants/care providers/personal assistants, nannies/student assistants, carpenters/bricklayers/construction workers, cleaners, nurses, and vehicle mechanics than in the general population. In the UNE population, assistant nurses and attendants/care providers/personal assistants were over-represented. Manual workers with CTS scored the preoperative QuickDASH higher than non-manual workers.

Conclusions
Manual workers are overrepresented among surgically treated CTS and UNE. Manual workers with CTS have more symptoms preoperatively than non-manual workers.

Published: May 2022

Purpose

68Gallium-labeled prostate-specific membrane antigen-11 (PSMA) PET/CT is the new reference to identify relapse during biochemical recurrence of prostate cancer (PCa). However, this method lacks specificity for bone foci. This study aimed to report the prevalence of PCa bone metastases and to assess the diagnostic performances of PSMA reporting and data systems (RADS), clinical, biological, and imaging features for identification.

Patients and Methods
A multicentric retrospective cohort of consecutive patients with biochemical recurrence after local treatment was analyzed. Clinical and biological features at initial staging and during recurrence were retrieved from medical reports. The metastatic status of each bone uptake on PSMA PET/CT was determined according to histopathology, comparisons with concomitant and previous conventional imaging, prostate-specific antigen kinetic, and follow-up. Two nuclear medicine physicians assessed PSMA-RADS, anatomic location, radiological patterns, SUVmax, and the presence of other molecular lesions. Univariate and multivariate analyses were conducted to identify independent predictors of PCa metastases.

Results
In the eligible population, 98/298 patients (32.9%) showed bone uptake on PSMA PET/CT. In patients with a final diagnosis, 28/81 lesions (34.6%) were metastases. PSMA-RADS-4 or 5 showed sensitivity of 79%, specificity of 94%, and accuracy of 89%. PSMA-RADS had a significantly higher area under the receiver operating characteristic curve than the initial reading in clinical practice (0.91 vs 0.83, P = 0.0074). Initial Gleason score ≥8, age ≤71 years at recurrence, and SUVmax >6.21 were independent predictors of PCa metastases in multivariate logistic regression (P = 0.0314, 0.0179, and 0.0003, respectively).

Conclusions
Most bone uptakes at PSMA PET/CT were benign lesions. PSMA-RADS, patients and tumor characteristics, and SUVmax could help identify PCa bone metastases.
Exploring governance issues between online food delivery platforms and restaurant partners in India
Authors: Yadav Nidhi , N. Meenakshi , Banerjee Parthasarathi 
Published: May 2022

Purpose
This paper aims to explore the governance of external entities that lie outside the boundaries of digital platform firms by using the theoretical lens of the transaction cost theory (TCT). TCT offers alternative modes of governance for effectively managing transactions in market, hierarchy or hybrid scenarios providing a perfect framework to study platform governance.

Design/methodology/approach
The paper explores governance issues between restaurant partners and online food delivery platforms in India via qualitative analysis of semi-structured interviews of various stakeholders, including restaurant partners and platform managers.

Findings
The study reveals that information asymmetry, opportunism, control and trust deficit are the major strategic governance issues in online food delivery platforms.

Research limitations/implications
Though care had been taken to cover all types of restaurants, due to lockdown number of restaurants studied was restricted in number. Despite the restrictions, findings provided valuable insights into the governance issues of the digital platform. Challenging times like Covid-19 make the study even more crucial from the strategic perspective. The study also adds to the literature on platform governance and provides practical implications for account managers and policymakers.

Practical implications
The study uncovers various critical governance issues. These, if resolved using the right combination of governance mechanisms, will lead to increased partner participation and value creation on the platform.

Originality/value
Platforms outsource the value creation to external entities without having any hierarchical control over partners. The paper studies governance outside the boundaries of the firm using TCT. Hence, it helps to extend governance outside the boundaries of the firm.
Evaluation of modified turbulent viscosity on shedding dynamic of three-phase cloud cavitation around hydrofoil – numerical/experimental analysis
Authors: Hasani Malekshah Emad , Wróblewski Wlodzimierz , Bochon Krzysztof , Majkut Mirosław 
Published: May 2022

PurposeThis paper aims to focus on the cavitating flow around the Clark-Y hydrofoil when the dissolved air is taken into account as the third phase. As the RNG k-epsilon model yields poor prediction due to overestimation of viscosity, the modification approaches including density corrected method, filter-based model and filter-based density correction model are used, and the turbulence model is modified. Also, the numerical results are compared with the experimental data.Design/methodology/approachThe cavitating flow is known as a complex multi-phase flow and appeared in the regions where the local pressure drops under saturation vapor pressure. Many researches have been conducted to analyze this phenomenon because of its significant impact on the erosion, vibration, noise, efficiency of turbomachines, etc.FindingsThe experiments are conducted in a rectangular test section equipped with Clark-Y hydrofoil providing cavity visualization, instantaneous pressure and vibration fluctuations. The simulations are carried out for different cavitation numbers with and without dissolved air. The Fast Fourier Transform, continues wavelet transform and temporal-spatial distribution of gray level are implemented to extract and compare the shedding frequency of experiments and numerical predictions and cavitation evolution. It is concluded that the flow structure, shedding frequency and time-averaged characteristics are highly influenced by the dissolved air. Also, the numerical prediction will be more satisfactory when the modified turbulence models are applied.Originality/valueTo the best of the authors’ knowledge, the originality of this study is the modification of the turbulence model for better prediction of cavitating flow, and the validation of numerical results with corresponding experimental data.
Open source software adoption for development of institutional repositories in university libraries of Islamabad
Authors: Kabir Khan Muhammad , Sheikh Arslan 
Published: May 2022

Purpose
This study aims to explore the present status of open-source institutional repository (IR) software’s usage in the university libraries of Islamabad. This study also investigates the views, satisfaction level and challenges of librarians in the adoption and use of IR software.

Design/methodology/approach
A survey was conducted to collect data from the Library Information Science (LIS) professionals working in the university libraries of Islamabad. Data were collected from all library professionals of the Islamabad university libraries by using a structured questionnaire. Out of the total 104 LIS professionals, 84 participated in the study with a response ratio of 80.76%.

Findings
The findings disclose that out of 23 universities recognized by Higher Education Commission (HEC) in Islamabad, 17 (public and private) have developed IRs. Currently, university libraries that have fully implemented the IRs are less as compared with those universities that have partially implemented IR software. However, a good number of university libraries are in the process to develop IRs. Free and open-source software is being used mostly in libraries as compared with in-house developed, locally developed or commercial software. The opinion of librarians about using IR software expressed a positive attitude of librarians. Some of the major challenges encountered by the librarians in using open-source IR software include selection of suitable software and materials for digitization, lack of cooperation from the parent organization, inadequate training opportunities and lack of skilled staff.

Research limitations/implications
This study is geographically limited to the university libraries in Islamabad.

Practical implications
This study will encourage the Pakistani LIS professionals to use open-source software for the development of IRs in their libraries.

Originality/value
This study concludes that the development of IRs in university libraries is a need of the hour. Although the launching of IRs requires certain skills and competencies, Pakistani librarians can overcome these challenges by mastering the ICT skills.
Understanding food choice factors of rural households from northwest Vietnam
Authors: Genova Christian , Umberger Wendy , Newman Suzie , Peralta Alexandra 
Published: May 2022

PurposeThis study aims to investigate the food choice motivations of rural households using a cross-sectional dataset of 510 households from northwest Vietnam interviewed in 2016.Design/methodology/approachA modified Food Choice Questionnaire (FCQ) is used to assess factors related to food choice and explore relationships between food choice factors, diet quality and various sociodemographic characteristics.FindingsResults show four distinct food choice factors: “Natural and healthy,” “Familiarity,” “Balanced diet” and “Convenience.” Two distinct consumer clusters are identified: “Health-conscious” households and “Pragmatic” households. “Health-conscious” households rank “Balanced diet” and “Natural and healthy” highly, while “Pragmatic” households prioritize “Convenience” and “Familiarity.” “Health-conscious” households have significantly more diverse diets, are wealthier and have a greater geographic concentration in the high vegetable density per capita-high elevation areas (36%). Their main food preparers are more educated and about 13% have Kinh ethnicity.Research limitations/implicationsFurther research is warranted to explore the temporal dimension of parental food choice motivations given the changing agrifood system in Vietnam.Originality/valueThis study is one of the few studies that assess the food choice motivations among ethnic minority groups in a rural setting.
Brand love and ethnic identification: the mediating role of brand attachment among African American consumers
Authors: Madadi Rozbeh , Torres Ivonne M. , Fazli-Salehi Reza , Zúñiga Miguel Ángel 
Published: May 2022

PurposeFrom a distinctiveness theory and elaboration likelihood model (ELM) perspective, this study aims to investigate the determinants, the direct and indirect effects of ethnic identification on brand attachment, brand love and behavioral outcomes. The authors examine two types of products (high- vs low-involvement).Design/methodology/approachIn a survey, participants were randomly assigned to four conditions consisting of two high-involvement (i.e. a smart watch and a car) and two low-involvement (i.e. a soda/soft drink and a shampoo) stimuli. A total of 192 respondents participated in this study; 39% were male, 61% were female and 90% were 18-22 years old.FindingsIn line with ELM, the authors offer evidence that ethnic advertising is more effective for low-involvement products targeted at African American consumers. Results also showed that brand attachment partially mediates the effect of ethnic identification with the ad (EthIdenAD) and brand love. In summary, the structural equation modeling (SEM) results support the efficacy of ethnic-targeted ads for developing brand attachment, brand love and behavioral outcomes.Practical implicationsUsing ethnically targeted ads to target minority groups may not be sufficient to increase the efficacy of ads. According to distinctiveness theory, African Americans with different levels of ethnic identification will respond differently to ad attitudes, brand attachment, brand love, identification with the model in the ad and varying degrees of belief that the ad was targeted toward them.Originality/valueThis study examines the effect of ethnically targeted advertising on brand love, and behavioral outcomes with the mediation effect of brand attachment and moderation effect of product involvement. The results of this study suggest several theoretical and practical implications for marketing and brand management, including directions for advertising strategy and consumer–brand relationships.
But did they get it “right”? Deadly force, body-worn camera footage, and hindsight bias
Authors: Roche Sean Patrick , Fenimore Danielle M. , Taylor Paul 
Published: May 2022

PurposeAmerican police agencies' swift adoption of body-worn camera (BWC) technology, coupled with the ubiquity of smartphones and social media, has led to a “new visibility” of policing. Video recordings are often touted as objective evidentiary accounts of police-civilian interactions. Yet even these recordings are rarely seen in a vacuum, but instead accompanied by headlines and accounts.Design/methodology/approachUsing a diverse sample of young American adults (N = 943) and an experimental design incorporating a short poorly recorded BWC video embedded within a survey, this study investigates perceptions of the appropriateness of police behavior in an ambiguous situation where officers used deadly force on a Black civilian. All respondents viewed the same video, but were randomly assigned to one of four ultimate outcomes.FindingsRespondents overwhelmingly reported the BWC video was personally important and significant for a subsequent investigation and public opinion. The experimental manipulation, along with background factors, exerted a substantial effect on perceptions of the officers' actions. Respondents found the officers' actions more appropriate when told the civilian held a weapon.Originality/valueAmericans are divided on the role of police in a democratic society. Objective accounts like video recordings may be used to build consensus, but our results, derived from a novel method and dataset, suggest deeper cognitive biases must also be overcome.
Benevolent leadership and organizational citizenship behaviors in a higher education context: a moderated mediation model
Authors: Nguyen Phong Dong , Khoi Nguyen Huu , Le Angelina Nhat Hanh , Ho Huong Xuan 
Published: May 2022

PurposeDrawing upon the conservation of resources (COR) theory, this paper investigates the moderated mediation model linking benevolent leadership to organizational citizenship behaviors towards the organization (OCBO) and towards individuals (OCBI) in the context of higher education. The mediating roles of leader-member exchange and affective commitment as well as the moderating roles of the two attachment styles—attachment anxiety and attachment avoidance—are also examined.Design/methodology/approachData were collected from a sample of 333 university lecturers and analyzed using partial least square structural equation modeling (PLS-SEM).FindingsThe results demonstrate that leader-member exchange and affective commitment are mediating resources that help benevolent leaders motivate university lecturers to engage in two types of OCBs. Moreover, attachment anxiety and attachment avoidance act as the respective enhancer and inhibitor for the indirect effects of benevolent leadership on both OCBs through leader-member exchange. In contrast, the relationships between benevolent leadership and two types of OCBs through the mediating role of affective commitment are not contingent on the attachment styles of lecturers.Practical implicationsThe findings suggest that university leaders who aim at promoting OCBs among lecturers should deploy benevolent leadership style to facilitate a positive social exchange relationship as well as foster their affective commitment. Such leadership style is especially effective in influencing lecturers who possess attachment anxiety personality traits.Originality/valueThis pioneer research develops and empirically tests a COR theory-grounded moderated mediation model pertaining to benevolent leadership and lecturers' OCBs. The findings contribute to the educational management literature by demonstrating that benevolent leadership, a crucial organizational resource, significantly motivates lecturers' voluntary and extra-role behaviors in a dynamic and contingent manner. Leader-member exchange and affective commitment are important mediating resources in the process of transforming benevolent leadership into beneficial behaviors. Further, the effectiveness of benevolent leadership largely depends on lecturers' personality traits of attachment anxiety and avoidance. These novel mediating and moderating findings demonstrate the sequential and interaction effects of various organizational and individual resources on lecturers' OCBs; thus, adding value to the COR theory's core principles, including resource caravans and resource investment behaviors.

Authors: Alimoglu Orhan , Colapkulu Nuray 
Published: May 2022

AbstractObjectiveImproving global surgery through postgraduate medical training in Africa is needed. In this context, implementing surgical residency programs into international developments for global surgery might play a great role to achieve successful results in low‐income countries. The aim of this study is to provide insight about postgraduate surgical training program that was initiated in Somalia where there was no prior formal surgical residency program.MethodologyA general surgery residency program was initiated within the collaboration of Istanbul Medeniyet University and Benadir University. Medical doctors from Somalia, who were successful on enrollment exams, were selected for the program. All residents completed a 3‐year course of theoretical and practical training, including 2 months at Istanbul Medeniyet University Department of General Surgery each year.ResultsSince 2013, 24 residents graduated from the program and 22 of them currently work as attending physicians in Somalia. Abdominal wall hernias, proctological diseases, cholelithiasis, thyroid diseases and breast diseases are the most common pathologies within the elective operations by graduated general surgeons. Also, appendectomy, infection‐induced perforation or ischaemia of colon and small bowel and acute mechanical intestinal obstruction due to tumours and adhesions are the most common emergency surgeries. Interventions due to blunt and penetrating trauma are frequently performed.ConclusionsThis surgical residency program provides surgical care and supports health systems in Somalia. We believe such programs are important to reduce global burden of surgical diseases.

Published: May 2022

AbstractObjectiveMost patients with pancreatic ductal adenocarcinoma receive chemo‐radiotherapy as first approach, some of them with the future hope to undergo surgery.MethodologyThe aim of the study was to estimate the probabilities to receive surgery, to experience tumour progression or post‐operative recurrence. We performed a competing‐risk approach to estimate competing events of disease progression and surgery, as well as post‐operative recurrence and death without recurrence.ResultsOf 96 enrolled patients, 49 received chemotherapy because they were judged borderline resectable, 21 were locally advanced and 7 had liver‐only limited metastatic disease. Competing‐risk analyses showed that resectability status at diagnosis not only determines future probabilities of surgery, but also tumour progression and post‐operative recurrence (p < .05 in all cases). CA19‐9 decrease ≥50% predicted surgery (p = .032), whereas CA19‐9 ≥ 300 U/mL predicted post‐operative recurrence (p = .001). Younger age also predicted surgery (p = .001) and margin status predicted recurrence (p = .047). The combination of the competing events suggested that the best outcomes since diagnosis depended not only on resectability and final surgical margin, but also on the combination of relative decrease of CA19‐9 and its absolute value after therapy.ConclusionsThe combination of CA19‐9 decrease, added to resectability criteria, can be used to optimise the selection of surgical candidates.

Authors: Mao Yingming , Wang Kaili 
Published: May 2022

AbstractThis study was performed to evaluate the effects of dietary Clanis bilineata larvae (CBL) on laying performance and biochemical blood parameters of Japanese quails. CBL was used to replace 10% corn meal of the basic diet to formulate the treatment feed, while the basic diet without CBL served as control feed. CBL treatment increased egg production, egg weight, egg mass, feed consumption, yolk ratio, shell ratio and egg shape index and serum total protein, albumin, globulin, high‐density lipoprotein cholesterol, low‐density lipoprotein cholesterol, IgG and IgG and decreased feed conversion ratio and albumin ratio of eggs and serum aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglycerides and total cholesterol. The results indicated that CBL could improve laying performance and health status of Japanese quails.
