How social media fosters the elders' COVID-19 preventive behaviors: perspectives of information value and perceived threat
Authors: Nguyen Tran Hung , Le Xuan Cu 
Published: April 2021

PurposeAlthough crisis communication via social media has engaged academia's attention during the disease outbreak, information value for preventive behaviors is inadequately studied. The purpose of this paper is to cast light on how to strengthen the uptake of older people's coronavirus disease 2019 (COVID-19) behavioral outcomes due to information value and perceived threat through social media.Design/methodology/approachThis study designs a survey and applies structural equation modeling to examine a research framework. A sample comprises 334 Vietnamese older participants who have utilized social media.FindingsThe results illustrate that preventive behaviors are determined by perceived threat (i.e. severity and susceptibility). Furthermore, older people heighten risk perceptions based on information characteristics, including information relevance, informative support and source credibility. Lastly, information relevance is a strong predictor of source credibility.Practical implicationsThe findings assist practitioners to enhance crisis communication effectiveness via social media by imparting valuable information to the public. Moreover, this paper offers overarching guidelines on the improvement in credibility with creators, risk consciousness and preventive behaviors.Originality/valueAlthough earlier studies focused attentiveness on the power of social media for raising threat perceptions, this work seems the first to unveil informative motives for perceived COVID-19 threat across older individuals, which subsequently presents plausible reasons for behavioral disclosure, including facemask-wearing, hand-washing and social distancing.
Readers' engagement through digital social reading on Twitter: the TwLetteratura case study
Authors: Pianzola Federico , Toccu Maurizio , Viviani Marco 
Published: April 2021

PurposeThe purpose of this article is to explore how participants with different motivations (educational or leisure), familiarity with the medium (newbies and active Twitter users), and participating instructions respond to a highly structured digital social reading (DSR) activity in terms of intensity of engagement and social interaction.Design/methodology/approachA case study involving students and teachers of 211 Italian high school classes and 242 other Twitter users, who generated a total of 18,962 tweets commenting on a literary text, was conducted. The authors performed both a quantitative analysis focusing on the number of tweets/retweets generated by participants and a network analysis exploiting the study of interactions between them. The authors also classified the tweets with respect to their originality, by using both automated text reuse detection approaches and manual categorization, to identify quotations, paraphrases and other forms of reader response.FindingsThe decoupling (both in space and time) of text read (in class) and comments (on Twitter) likely led users to mainly share text excerpts rather than original personal reactions to the story. There was almost no interaction outside the classroom, neither with other students nor with generic Twitter users, characterizing this project as a shared experience of “audiencing” a media event. The intensity of social interactions is more related to the breadth of the audience reached by the user-generated content and to a strong retweeting activity. In general, better familiarity with digital (social) media is related to an increase in the level of social interaction.Originality/valueThe authors analyzed one of the largest educational social reading projects ever realized, contributing to the still scarce empirical research about DSR. The authors employed state-of-the-art automated text reuse detection to classify reader response.

Purpose
Measuring parent satisfaction is regarded as essential but there is a paucity of research reporting on parental satisfaction with community youth mental health services. This study aims to examine parent satisfaction with Jigsaw – a primary care youth mental health service.

Design/methodology/approach
A measure of parent satisfaction was developed and administered to parents in 12 Jigsaw services over a two-year period (n = 510, age range: 28 to 70 years) when young people and parents were ending their engagement with these services.

Findings
Overall, parents had high levels of satisfaction with Jigsaw and their level of satisfaction did not vary depending on the parent or young person’s age and/or gender. Examination of qualitative feedback revealed three overarching themes relating to growth and change in young people, parents and their families; strengths of the service and; suggestions for future service development. Analysis of the psychometric properties of the measure provided evidence for a two-factor structure examining satisfaction with the intervention and outcomes and service accessibility and facilities.

Originality/value
This study represents one of the first efforts to measure parent satisfaction with primary care youth mental health services. It has resulted in the development of a brief measure that can be more widely administered to parents engaging with primary care youth mental health services.

Published: April 2021

AbstractSkin graft vascularization is investigated mainly by histological evaluation. Immunohistochemical analysis has been conducted only in mice. Transcutaneous oxygen tension (TcPO2), which is an index of blood flow, has not been evaluated in skin grafts and only a few studies have reported biologic monitoring data using color tone evaluation and surface temperature. In humans, these tests can be performed non‐invasively. To evaluate human skin graft vascularization, we analyzed biomonitoring data after skin grafting. We evaluated 14 patients who underwent skin grafting surgery at Nagoya City University Hospital. The TcPO2, color tone, surface temperature, and dermoscopic observations at recipient sites were measured at postoperative day (POD) 4, 6, and 11. Mean TcPO2 levels at POD4, 6, and 11 were 12.7, 15.2, and 33.5 mmHg, respectively, and significantly higher at POD11 than at POD4 (p = 0.003, Steel–Dwass test). Dermoscopic observation revealed gradually increasing redness and yellowness. Color tone evaluation measured by spectrophotometry supported the appearance. The a*(redness) value at POD4, 6, and 11 was 6.19, 9.20, and 11.27, respectively, and significantly higher at POD11 than at POD4 (p < 0.001, Steel–Dwass test). The b*(yellowness) value at POD4, 6, and 11 was 8.83, 9.24, and 13.02, respectively, and significantly higher at POD11 than at POD4 (p = 0.020, Steel–Dwass test). The surface temperature did not significantly differ between graft and control sites. These findings suggest that skin graft vascularization started by POD6 and stabilized by POD11. Because TcPO2 increases after POD4, skin grafts should remain undisturbed until at least POD11.
Mitigating Psychic Distance and Enhancing Internationalization of Fintech SMEs from Emerging Markets: The Role of Board of Directors

Published: April 2021

AbstractPrior research suggests that corporate boards and directors play important roles in firm strategy and performance. In this paper, we examine an important yet under‐explored avenue and focus on their role in overcoming the multilevel psychic distance (PD) faced by internationalizing small and medium‐sized enterprises (SMEs) originating from an emerging market. Analysing Indian Fintech SMEs, using multiple case studies, our findings reveal that boards contribute important network‐level resources and knowledge about foreign markets, which in turn assists internationalizing SMEs in mitigating PD. We demonstrate that the human and social capital of boards play important, yet distinctly different, roles in mitigating PD at pre‐ and post‐internationalization phases. At the pre‐internationalization phase, directors’ prior international and industry experience, as well as board interlocks and prior connections, are most valuable, whereas at the post‐entry phase, transnational boards, and those with stronger trust‐based personal relationships (i.e. greater depth of social capital, facilitate faster experiential learning. Taken together, our findings contribute novel insights into the mechanisms through which boards affect the outcomes of firms operating, and originating from, extreme institutional environments. Further, we draw implications for research and practice.

AbstractObjectiveFixed ratio blood product administration may improve outcomes in trauma patients with massive blood loss. The present study aimed to describe the impact of a major haemorrhage protocol (MHP) on the ratio of blood products administered for paediatric major trauma.MethodsRetrospective observational study in a state‐designated paediatric major trauma centre in Melbourne, Australia. Children with major trauma who received blood products in the ED were identified from a hospital trauma registry. Blood product ratios before, during and after implementation of a hospital MHP were compared in consecutive 2 year blocks.ResultsOver a 6 year period, 767 major trauma patients were identified, of whom 47 received blood products in the ED and were included in the analysis; 14 pre‐MHP implementation, 24 during‐MHP implementation and nine post‐MHP implementation. No patients received blood products at a ratio of 1:1:1 for red blood cells:fresh frozen plasma:platelets, respectively, during any time period. In this cohort of predominantly blunt trauma, blood products were infrequently administered in the ED because of the low prevalence of massive blood loss. Coagulopathy and hypofibrinogenaemia were commonly observed, nearly half of included patients were managed operatively and one quarter did not survive their injuries.ConclusionThe implementation of a MHP did not change the ratio of blood product administration in this cohort of patients because of the infrequency of massive blood loss. Future studies may focus on the impact of treating coagulopathy and hypofibrinogenaemia on patient‐centred outcomes.

AbstractThe gut bacteria of honey bee recognized as a mutualistic partner with the insect host might have originated from a free‐living or parasitic lifestyle. However, little is known about the genomic features underlying this lifestyle transition. Here we compared the genomes of bee gut bacteria Apibacter with their close relatives living in different lifestyles. We found that despite general reduction in the Apibacter genome, genes involved in amino acid synthesis and monosaccharide detoxification were retained, which is putatively beneficial to the host. Interestingly, the microaerobic Apibacter species specifically acquired genes encoding for the nitrate respiration (NAR). These together with nitrate transporter and enzymatic cofactor synthesis genes were found clustered in the genomes. The NAR system is also conserved in the cohabitating bee gut microbe Snodgrassella, although with a different structure. This convergence suggests a key role of respiratory nitrate reduction for microaerophilic microbiomes to colonize bee gut epithelium. Genes involved in lipid, histidine degradation were found partially or completely lost in Apibacter. Particularly, genes encoding for the conversion to the toxic intermediates in phenylacetate degradation, as well as other potential virulence factors, are specifically lost in Apibacter group. Antibiotic resistance genes are only sporadically distributed among Apibacter species, but are prevalent in their relatives, which may be related to the remotely living feature and less exposure to antibiotics of their bee hosts. Collectively, this study advanced our knowledge of genomic features specialized to bee gut symbionts.

Published: April 2021

AbstractBackgroundWe report a subgroup analysis of afatinib with respect to its efficacy, safety, and the long‐term survival of patients in a Named Patient Use program at a single institution.MethodsWe analyzed 60 patients with stage IV non‐small cell lung cancer (NSCLC) who had been treated with ≥1 line of platinum‐based chemotherapy and had activating epidermal growth factor receptor (EGFR) mutations or disease control for ≥6 months with prior EGFR inhibitors. Afatinib was started on a daily dose of 50 mg, which was decreased according to the adverse events and tolerability.ResultsA total of 13 patients achieved partial remission, whereas 33, 12, and two showed stable disease, had progression, and were not evaluable, respectively, resulting in an objective response rate and disease control rate of 21.7% and 76.7%, respectively. The median progression‐free survival (PFS) was 5.4 (95% confidence interval [CI]: 4.0–7.7) months and median overall survival (OS) was 10.1 (8.5–13.6) months. Toxicities leading to drug discontinuation were experienced by four patients (6.7%). Grade 3 diarrhea occurred in 10 patients (16.7%), and afatinib dose reductions were required in 35 patients. The PFS and OS were significantly longer for patients whose dose was reduced to 40 or 30 mg than for those without dose reduction (7.0 vs 3.1 months and 13.5 vs 8.1 months, respectively, p < 0.05).ConclusionsThe efficacy of afatinib was similar to that identified in the global data without unexpected adverse events. Survival analyses support the currently approved dose of afatinib as first‐line treatment for NSCLC.

Published: April 2021

AbstractBackgroundAlthough perineural invasion is a well known prognostic factor used in several cancers, its prognostic role in esophageal squamous cell carcinoma remains controversial. Here, we investigated the prognostic role of perineural invasion in surgically treated esophageal squamous cell carcinoma.MethodsWe retrospectively reviewed the medical records of 316 patients who underwent esophagectomy and lymph node dissection for esophageal squamous cell carcinoma between 2007 and 2016.ResultsOverall, 287 men (mean age: 62.73 ± 7.97 years) were included in the study. The median follow‐up period was 35.97 ± 30.99 months, perineural invasion was confirmed in 25 patients, and three‐year overall and disease‐free survival were significantly lower in the perineural invasion group than in the no‐perineural invasion group (75.9% vs. 40.0%, p < 0.001; 70.3% vs. 21.6%, p < 0.001). Cumulative incidences of locoregional recurrence and distant metastasis over three years were higher in the perineural invasion group (13.8% vs. 9.6%, p = 0.009 and 52.8% vs. 14.6%, p < 0.001). On performing multivariable analysis, perineural invasion, pathological stage, incomplete resection, and neoadjuvant therapy were adverse risk factors for disease‐free survival. The concordance index increased when perineural invasion was included in the model (0.712 vs. 0.723). On subgroup analysis, perineural invasion demonstrated a prognostic value in node‐negative patients (79.4% vs. 35.7%, p = 0.012).ConclusionsPerineural invasion was found to be an adverse risk factor for disease‐free survival in surgically treated patients with esophageal squamous cell carcinoma. Close observation and individualized adjuvant therapy may be helpful for patients with perineural invasion.
A motion‐detection based camera trap for small nocturnal mammals with low latency and high signal‐to‐noise ratio
Authors: Klemens Jeffrey A. , Tripepi Manuela , McFoy Shane A. 
Published: April 2021

Abstract

Camera traps are useful for monitoring wildlife populations, but traps may not always trigger when targeting small, nocturnal species. Motion‐detection techniques have advantages over time‐lapse and heat‐triggered traps, but need to be deployed to maximize signal‐to‐noise ratio.

As part of a study of flying squirrels (Glaucomys) in urban environments we developed motion‐detecting camera traps using a raspberry pi microcomputer and camera and a 940 nm IR illuminator on a tree‐mounted wooden platform. The system was built from commercially available parts and was comparable in cost to a consumer camera trap, although this cost did not include a waterproof housing. We compared the performance of our system to commercial trailcams.

Four pi cameras successfully documented visits by Glaucomys and other animals to bait placed on the platform over three nights at four wooded sites: suburban and rural backyards, a private outdoors club and a small urban nature reserve (16 camera X site combinations, 48 trap nights). The traps showed low latency, with an average of <1 night until detection of Glaucomys at each site. Data collected had a high signal‐to‐noise ratio; of 2,182 capture events 55% documented Glaucomys, 40% documented non‐target mammals, 1% were caused by large insects and the remaining 4% were unknown. Commercial camera traps placed at the sites failed to capture many of these events.

The low cost and high signal‐to‐noise ratio of this system may make it easy to adapt for other small animal applications. The main modification required to deploy this system in new situations will be in locating or providing a fixed or static background against which animals can be observed and in using masking techniques within motion‐detection software.
Innovations in movement and behavioural ecology from camera traps: Day range as model parameter

Published: April 2021

Abstract

Camera‐trapping methods have been used to monitor movement and behavioural ecology parameters of wildlife. However, when considering movement behaviours to estimate DR is mandatory to include in the formulation the speed ratio, otherwise DR results will be biased. For instance, some wildlife populations present movement patterns characteristic of each behaviour (e.g. foraging or displacement between habitat patches), and further research is needed to integrate the behaviours in the estimation of movement parameters. In this respect, the day range (average daily distance travelled by an individual, DR) is a model parameter that relies on movement and behaviour. This study aims to provide a step forward concerning the use of camera‐trapping in movement and behavioural ecology.

We describe a machine learning procedure to differentiate movement behaviours from camera‐trap data, and revisit the approach to consider different behaviours in the estimation of DR. Second, working within a simulated framework we tested the performance of three approaches to estimate DR: DROB (i.e. estimating DR without behavioural identification), DRTB (i.e. estimating DR by identifying behaviours manually and weighting each behaviour on the basis of the encounter rate obtained) and DRRB (i.e. estimating DR based on the classification of movement behaviours by a machine learning procedure and the ratio between speeds). Finally, we evaluated these approaches for 24 wild mammal species with different behavioural and ecological traits.

The machine learning procedure to differentiate behaviours showed high accuracy (mean = 0.97). The DROB approach generated accurate results in scenarios with a speed‐ratio (fast relative to slow behaviours) lower than 10, and for scenarios in which the animals spend most of the activity period on the slow behaviour. However, when considering movement behaviours to estimate DR is mandatory to include in the formulation the speed ratio, otherwise the DR results will be biased. The new approach, DRRB, generated accurate results in all the scenarios. The results obtained from real populations were consistent with the simulations.

In conclusion, the integration of behaviours and speed‐ratio in camera‐trap studies makes it possible to obtain unbiased DR. Speed‐ratio should be considered so that fast behaviour is not overrepresented. The procedures described in this work extend the applicability of camera‐trap‐based approaches in both movement and behavioural ecology.

Published: April 2021

BackgroundPost‐operative organ complications in liver resection surgery are not uncommon. This prospective observational pilot study was performed to evaluate the incidence, degree and timing of myocardial, renal and intestinal injury in patients undergoing liver resection surgery using the low central venous pressure (LCVP) technique and the Pringle manoeuvre.MethodsBlood samples were obtained before, during and after elective liver resection until post‐operative day (POD) 5. High‐sensitive troponin T (hs‐TnT), serum creatinine, urea, intestinal fatty acid binding protein (I‐FABP), D‐lactate, arterial lactate, portal lactate, amylase, as well as urine N‐acetyl‐ß‐D‐glucosaminidase (NAG) were analysed. Systemic haemodynamics were measured intraoperatively.ResultsEighteen patients fulfilled the protocol. The Pringle manoeuvre was used in all but 1 patient. hs‐TnT increased significantly over time (P < .001) and 5 patients (28%) developed myocardial injury. Five patients had a pre‐operative elevation of hs‐TnT, four of those developed myocardial injury. Serum creatinine increased significantly over time (P = .015). Acute kidney injury (AKI) occurred in 5 patients (28%), while NAG, as a marker of tubular injury, was not affected. I‐FABP increased over time (P < .001) with a maximal 75% increase at 3 hours after resection. D‐lactate was below detection level at all measuring points.ConclusionsIn patients undergoing liver resection surgery, using LCVP technique and Pringle manoeuvre, myocardial injury was seen in approximately 30% of the patients post‐operatively and almost 30% developed transient AKI in the early post‐operative period with no tubular injury. Furthermore, a transient increase of the enterocyte damage marker I‐FABP was demonstrated with no signs of gut barrier dysfunction.
