Influencer marketing
Authors: Stubb Carolina , Nyström Anna-Greta , Colliander Jonas 
Published: May 2019

PurposeThe purpose of this paper is to investigate the effects of a particular form of sponsorship disclaimer in sponsored content by social media influencers (SMIs), namely a sponsorship compensation justification disclosure. A sponsorship compensation justification disclosure explains why influencers and brands engage in sponsorship collaborations by providing a normative reason that justifies the existence and dissemination of sponsored content.Design/methodology/approachAn experimental design was used to compare the effects of a sponsorship compensation justification disclosure made by either an influencer or the sponsoring brand, to a simple sponsorship disclosure and a no disclosure control post, on consumers’ responses to a product-review video by a YouTube influencer.FindingsThe paper offers empirical evidence that sponsorship compensation justification generates more positive consumer attitudes toward influencers receiving sponsorship compensation, and increases source and message credibility, compared to a simple sponsorship disclosure.Research limitations/implicationsThe hypotheses were tested on one YouTube video, comprising of a single product category, one SMI and one social media platform. Further studies might replicate the experiment on different product categories and on different social media platforms.Practical implicationsThis empirical study can offer brand communication managers and influencers important information on how to communicate and design sponsorship disclosures to reach-desired responses from consumers.Originality/valueThe study is the first study to empirically demonstrate the effects of this particular type of sponsorship disclosure.
A critical review of female firefighter protective clothing and equipment workplace challenges
Authors: McQuerry Meredith , Kwon Cassandra , Johnson Heather 
Published: May 2019

Purpose
The purpose of this paper is to identify the challenging barriers faced by female firefighters, which limit workplace entrance and performance.

Design/methodology/approach
Occupational barriers from both psychological and physiological viewpoints were explored based on previous literature and the reported experiences of female firefighters.

Findings
A comprehensive review of literature synthesizes previous studies pertaining to gender anthropometric differences, female firefighters’ experiences in the work environment and protective clothing issues. The physical capabilities of men and women in specific relation to performing firefighting activities are also examined. Issues of greatest concern are identified for personal protective clothing (PPC) and equipment, which have traditionally been designed for the male human form. This leads to a lack of protection, an increased risk of onsite injury, reduction in mobility and poorer comfort for female firefighters.

Originality/value
This review provides an original overview of the critical workplace challenges faced by female firefighters. The need for female-specific PPC and equipment is specifically addressed to retain the growing number of women entering the male-dominated firefighting profession.
Market valuation and risk profile of listed European football clubs
Authors: Prigge Stefan , Tegtmeier Lars 
Published: May 2019

Purpose
The purpose of this paper is to explore whether stocks in football clubs are valued in line with the valuation of other capital assets in the capital market. Moreover, it analyzes the risk profile of football stocks. By taking this perspective, the paper also contributes to the discussion on the motives of those who invest in football clubs, particularly the question of whether they expect extra benefits, i.e., in addition to dividends and share price appreciation, from the investments.

Design/methodology/approach
The empirical study analyzes the share prices of 19 listed European football clubs from January 2010 to December 2016. Building on the capital asset pricing model, the authors used Zellner’s (1962) seemingly unrelated regressions.

Findings
The results indicate that the majority of the football clubs in the sample are overvalued. This implies that investments in football stocks are mainly attractive for those investors who expect to derive extra benefits from their investment. That might be likely for strategic, patron and fan investors, but not for purely financial investors.

Research limitations/implications
As a next step, more advanced factor models could be applied to the analysis.

Practical implications
For investors, the results imply that portfolio diversification is particularly beneficial while buying football stocks. For football clubs, the rather low general market risk, combined with the overvaluation, leads to low equity costs when new shares are issued.

Originality/value
The results suggest that dividends and share price appreciation are not the only benefits football stock owners derive from the stocks, thus underlining that further investigations in their motives to hold football stocks are very promising.

AbstractToxic epidermal necrolysis (TEN) is a rare condition, causing life‐threatening adverse cutaneous reactions. TEN occurrence after bone marrow transplantation (BMT) is a well‐known phenomenon; however, to date, only a few cases have been reported in the published work. Here, we describe the case of a 53‐year‐old woman who experienced TEN after undergoing allogenic BMT for malignant lymphoma. Skin erosion spread across a maximum of 70% of the body surface area and severe mucosal lesions developed. Steroid pulse therapy, plasma apheresis and immunoglobulin therapy were administrated, which resulted in the complete resolution of TEN. However, she developed hemophagocytic lymphohistiocytosis and died 38 days after BMT, owing to rupture of the lower digestive tract complicated by multi‐organ failure. In our case, engraftment failure occurred, and the peripheral white blood cell count was less than 100/μL during the TEN course, suggesting that the presence of only a few immune cells could cause TEN. Our findings showed that high mortality rates and widespread skin erosion could be regarded as the most important characteristics of TEN occurring after BMT.

AbstractHinokitiol, a component of the essential oil isolated from Cupressaceae, possesses antibacterial and antifungal activities and has been used in oral care products. In this study, the antibacterial activities of hinokitiol toward various oral, nasal and nasopharyngeal pathogenic bacteria, including Streptococcus mutans, Streptococcus sobrinus, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Fusobacterium nucleatum, methicillin‐resistant and ‐susceptible Staphylococcus aureus, antibiotic‐resistant and ‐susceptible Streptococcus pneumoniae, and Streptococcus pyogenes were examined. Growth of all these bacterial strains was significantly inhibited by hinokitiol, minimal inhibitory concentrations of hinokitiol against S. mutans, S. sobrinus, P. gingivalis, P. intermedia, A. actinomycetemcomitans, F. nucleatum, methicillin‐resistant S. aureus, methicillin‐susceptible S. aureus, antibiotic‐resistant S. pneumoniae isolates, antibiotic‐susceptible S. pneumoniae, and S. pyogenes being 0.3, 1.0, 1.0, 30, 0.5, 50, 50, 30, 0.3–1.0, 0.5, and 0.3 μg/mL, respectively. Additionally, with the exception of P. gingivalis, hinokitiol exerted bactericidal effects against all bacterial strains 1 hr after exposure. Hinokitiol did not display any significant cytotoxicity toward the human gingival epithelial cell line Ca9‐22, pharyngeal epithelial cell line Detroit 562, human umbilical vein endothelial cells, or human gingival fibroblasts, with the exception of treatment with 500 μg/mL hinokitiol, which decreased numbers of viable Ca9‐22 cells and gingival fibroblasts by 13% and 12%, respectively. These results suggest that hinokitiol exhibits antibacterial activity against a broad spectrum of pathogenic bacteria and has low cytotoxicity towards human epithelial cells.
Detection of microRNAs in DNA Extractions for Forensic Biological Source Identification
Authors: Lewis Carolyn A. , Layne Tiffany R. , Seashols‐Williams Sarah J. 
Published: May 2019

AbstractMolecular‐based approaches for biological source identification are of great interest in the forensic community because of a lack of sensitivity and specificity in current methods. MicroRNAs (miRNAs) have been considered due to their robust nature and tissue specificity; however, analysis requires a separate RNA extraction, requiring an additional step in the forensic analysis workflow. The purpose of this study was to evaluate miRNA detection in blood, semen, and saliva using DNA extraction methods commonly utilized for forensic casework. RT‐qPCR analysis revealed that the tested miRNAs were consistently detectable across most tested DNA extraction methods, but detection was significantly reduced compared to RNA extracts in some biological fluids. DNase treatment was not necessary to achieve miRNA‐specific results. A previously developed miRNA panel for forensic body fluid identification was evaluated using DNA extracts, and largely demonstrated concordance with results from samples deriving from RNA extracts of semen, blood, and saliva.
Impact of a Novel Cryoprotectant Blend on the Sensory Quality of Frozen Lobster (Homarus americanus)
Authors: English Marcia M. , Keough James, M. , McSweeney Mathew B. , Gulam Razul M. S. 
Published: May 2019

AbstractFrozen storage of lobster meat (Homarus americanus) can result in undesirable quality changes that decrease consumer acceptability of these products. Current seafood industry methods use cryoprotective agents that contain phosphates including sodium tripolyphosphates (STPP). However, recent evidence suggests that cryoprotective mixtures that combine different carbohydrates and STPP can have equal or even greater cryoprotective properties compared to using STPP alone. The objective of this study was to compare the overall consumer acceptability of lobster meat stored for 6 months in different blends of these cryoprotective solutions. One hundred and seven panelists were recruited to score the acceptability of the lobster samples using nine‐point hedonic scales. A check‐all‐that‐apply (CATA) question containing 27 literature‐informed, sensory descriptors was also used to identify terms frequently used to describe lobster meat. Analysis of variance analysis, indicated a significant increase for overall liking (22.1%, P < 0.0001), liking of flavor (23.6%, P < 0.0001) and texture (15.6%, P = 0.000) scores for samples stored in a novel carbohydrate blend plus sodium chloride (NaCl) and STPP compared to the water control. Subsequent penalty analysis revealed that overall liking scores were most positively associated with the attributes tender, sweet, moist and soft. Moreover, the attributes with the highest positive mean impact were more frequently used to describe lobster samples stored in solutions containing NaCl and the novel carbohydrate blend, as well as NaCl and STPP (Lobster‐3 and Lobster‐5 samples, respectively).Practical ApplicationThe positive impact on the sensory quality of this novel blend of cryoprotective compounds (carbohydrates and NaCl) is proof of concept that this mixture is comparable, if not better than preservatives currently used by the seafood industry. Given the necessary regulatory approval and industry acceptance, lobster processors may consider this novel blend as a suitable alternative to freeze lobster products for up to 6 months.
Potential KPC‐2 carbapenemase reservoir of environmental Aeromonas hydrophila and Aeromonas caviae isolates from the effluent of an urban wastewater treatment plant in Japan

Published: May 2019

SummaryAeromonas hydrophila and Aeromonas caviae adapt to saline water environments and are the most predominant Aeromonas species isolated from estuaries. Here, we isolated antimicrobial‐resistant (AMR) Aeromonas strains (A. hydrophila GSH8‐2 and A. caviae GSH8M‐1) carrying the carabapenemase blaKPC‐2 gene from a wastewater treatment plant (WWTP) effluent in Tokyo Bay (Japan) and determined their complete genome sequences. GSH8‐2 and GSH8M‐1 were classified as newly assigned sequence types ST558 and ST13, suggesting no supportive evidence of clonal dissemination. The strains appear to have acquired blaKPC‐2‐positive IncP‐6‐relative plasmids (pGSH8‐2 and pGSH8M‐1‐2) that share a common backbone with plasmids in Aeromonas sp. ASNIH3 isolated from hospital wastewater in the United States, A. hydrophila WCHAH045096 isolated from sewage in China, other clinical isolates (Klebsiella, Enterobacter and Escherichia coli), and wastewater isolates (Citrobacter, Pseudomonas and other Aeromonas spp.). In addition to blaKPC‐2, pGSH8M‐1‐2 carries an IS26‐mediated composite transposon including a macrolide resistance gene, mph(A). Although Aeromonas species are opportunistic pathogens, they could serve as potential environmental reservoir bacteria for carbapenemase and AMR genes. AMR monitoring from WWTP effluents will contribute to the detection of ongoing AMR dissemination in the environment and might provide an early warning of potential dissemination in clinical settings and communities.
Ethnic board diversity, earnings quality and institutional investors: evidence from Malaysian corporate boards
Authors: Tee Chwee Ming , Rassiah Puspavathy 
Published: May 2019

AbstractMotivated by calls to examine the issue of board diversity in emerging economies, this study explores the association between ethnic board diversity and earnings quality; and the moderating effect of institutional investors’ ownership. In a sample of Malaysian firms, we find that boards with higher ethnic diversity are associated with higher earnings quality. Consequently, our findings suggest that institutional investors prefer boards to be ethnically diverse. Consistent with geographical proximity theory, this effect is primarily driven by domestic institutional investors. Finally, we find that political connection attenuates the association between ethnic board diversity and higher earnings quality.

Published: May 2019

AbstractThough the ovine stifle is commonly used to study osteoarthritis, there is limited information about the age‐related morphometric changes of the tidemark. The objective of this study was to document the number of tidemarks in the stifle of research sheep without clinical signs of osteoarthritis and of various ages (n = 80). Articular cartilage of the medial and lateral tibial condyles and of the medial and lateral femoral condyles was assessed by histology: (a) to count the number of tidemark; and (b) to assess the OARSI (Osteoarthritis Research Society International) score for structural changes of cartilage. The number of tidemarks varied between anatomical regions, respectively, from 4.2 in the medial femoral condyle to 5.0 in the lateral tibial condyle. The axial part showed a significant higher number of tidemarks than the abaxial part, for all regions except the medial tibial condyle. Whilst the tidemark count strongly correlated with age (Spearman's correlation coefficient = 0.70; 95% confidence interval (95% CI): 0.67–0.73; p < 0.0001), the OARSI score was weakly correlated with age in our cohort of sheep (Spearman's correlation coefficient = 0.25; 95% CI: 0.19–0.30; p < 0.0001). Interestingly, no tidemark was seen in the three animals aged 6 months. Our data indicate that the number of tidemarks increases with age and vary with anatomical region. The regional variation also revealed a higher number of tidemarks in the tibia than in the femur. This could be attributed to the local variation in cartilage response to strain and to the difference in chondrocyte biology and density.

Published: May 2019

BackgroundCurrent evidence suggests that preimplantation genetic testing for aneuploidy (PGT‐A) used during assisted reproductive technology improves per‐cycle live‐birth rates but cumulative live‐birth rate (CLBR) was similar to a strategy of morphological assessment (MA) of embryos. No study has assessed the cost‐effectiveness of repeated cycles withPGT‐A using longitudinal patient‐level data.AimTo assess the cost‐effectiveness of repeated cycles withPGT‐A compared toMAof embryos in older women.Materials and MethodsMicro‐costing methods were used to value direct resource consumption of 2093 assisted reproductive technology‐naïve women aged ≥37 years undergoing up to three ‘complete assisted reproductive technology cycles’ (fresh plus cryopreserved embryos) with eitherPGT‐A orMAin an Australian clinic between 2011 and 2014. Incremental cost‐effective ratios were calculated from healthcare and patient perspectives with uncertainty assessed using non‐parametric bootstrap methods. Cost‐effectiveness acceptability curves were constructed to evaluate the probability ofPGT‐A being cost‐effective over a range of willingness‐to‐pay thresholds.ResultsTheCLBRand mean healthcare costs per patient were 30.90% and $22 962 for thePGT‐A group, and 26.77% and $21 801 for theMAgroup, yielding an incremental cost‐effective ratio of $28 103 for an additional live birth withPGT‐A. At a willingness‐to‐pay threshold of $50 000 and above, there is more than an 80% probability ofPGT‐A being cost‐effective from the healthcare perspective and a 50% likelihood from a patient perspective.ConclusionThis is the first study to use real‐world patient‐level data to assess the cost‐effectiveness ofPGT‐A in older women from the healthcare and patient perspectives. The findings contribute to the ongoing debate on the role ofPGT‐A in clinical practice.

Published: May 2019

SummaryFacemask ventilation is an essential part of airway management. Correctly predicting difficulties in facemask ventilation may reduce the risk of morbidity and mortality among patients at risk. We aimed to develop and evaluate a weighted risk score for predicting difficult facemask ventilation during anaesthesia. We analysed a cohort of 46,804 adult patients who were assessed pre‐operatively airway for 13 predictors of difficult airway management and subsequently underwent facemask ventilation during general anaesthesia. We developed the Difficult Facemask (DIFFMASK) score in two consecutive steps: first, a multivariate regression analysis was performed; and second, the regression coefficients of the adjusted regression model were converted into a clinically applicable weighted point score. The predictive accuracy of the DIFFMASK score was evaluated by assessment of receiver operating characteristic curves. The prevalence of difficult facemask ventilation was 1.06% (95%CI 0.97–1.16). Following conversion of regression coefficients into 0, 1, 2 or 3 points, the cumulated DIFFMASK score ranged from 0 to 18 points and the area under the receiver operating characteristic curve was 0.82. The Youden index indicated a sum score ≥ 5 as an optimal cut‐off value for prediction of difficult facemask ventilation giving a sensitivity of 85% and specificity of 59%. The DIFFMASK score indicated that a score of 6–10 points represents a population of patients who may require heightened attention when facemask ventilation is planned, compared with those patients who are obviously at a high‐ or low risk of difficulties. The DIFFMASK score may be useful in a clinical context but external, prospective validation is needed.

SummaryMonoMAC is a complex primary immunodeficiency caused by mutations in the myeloid transcription factor GATA2, characterized by multilineage cytopenia with malignant complications and severe infections, including mycobacteria and herpesviruses. We describe the clinical presentation, genetics and antiviral inflammatory responses in a small case series. Two patients presented in childhood with mycobacterial infection and were diagnosed with MonoMAC germline GATA2 variants; their healthy fathers with the same mutations were also studied. Three patients were elderly individuals with acquired GATA2 mutations and malignant haematological conditions. Overall, this study demonstrates the heterogeneous clinical presentation and variation in immunodeficiency caused by GATA2 mutations.
