Authors: da Costa Senior Oliver , De Temmerman Griet , Falter Bart , Politis Constantinus 
Published: March 2021

Abstract
Repeated sagittal split osteotomy might impose an increased risk for damage of the inferior alveolar nerve. Another contemporary orthognathic issue is surgical management of malocclusion following condylar resorption. Here we describe a modified C-osteotomy technique as a proposed solution for these difficulties in orthognathic surgery. The modified C-osteotomy might induce less stress on the condyles reducing the risk for relapse subsequent to condylar resorption, as well as reduce the risk of inferior alveolar nerve damage.
Sports-Related Craniofacial Injuries Among Pediatric and Adolescent Females: A National Electronic Injury Surveillance System Database Study
Authors: Kim Minji , Moeller Ellie , Thaller Seth R. 
Published: March 2021

Background:
Number of female athletes continues to exponentially increase in all sports; however, available literature detailing craniofacial injuries remains scarce. Compared to male athletes, female athletes may experience different types of injuries. These may be related to sex differences such as craniofacial pain and dimensions. Thus, this study assesses the type of sport and craniofacial injuries that pediatric and adolescent female athletes sustain.

Methods:
National Electronic Injury Surveillance System was analyzed for all hospital admissions for young female athletes (5–24 years old) experiencing a sports-related craniofacial injury. These included contusions and abrasions, lacerations, fractures, and hematomas. Following sports were analyzed for craniofacial injury: basketball, golf, soccer, ice skating, swimming, softball, horseback riding, volleyball, field hockey, and football.

Results:
Most of the sports-related craniofacial injury occurred in female athletes who are between 10 and 19 years old. Across all age groups, softball (34.9%), basketball (28.1%), and soccer (15.6%) caused majority of the craniofacial injuries. The most common presenting craniofacial injury types were contusions and abrasions as well as lacerations.

Conclusions:
There is a need for improved protective gear, such as face shields and low-impact balls, especially in softball and basketball. Physicians should consider the differences in female versus male and child versus adult injury pattern when treating female athletes in order to prevent long-term complications, such as scarring and depression. Overall, sports-related craniofacial injuries among female athletes need to be further examined as the epidemiology of their injuries and their health needs are unique.

Published: March 2021

Background:
Computer-based training modules use various multimedia components such as text, graphics, animation, and videos that can theoretically facilitate the learning process. Splenic flexure mobilization (SFM) is a crucial step for tension-free colorectal/anal anastomosis that can be a technically demanding step. This study is designed to demonstrate our novel training module for SFM with high-vessel ligation during surgery and present the anatomical landmarks and embryological plans for SFM.

Materials and Methods:
A step-by-step educational video was prepared to standardize and teach the technical steps of the SFM. 3D animation was prepared and cadaveric dissection was performed in a step-by-step manner similar to minimally invasive surgery. This is followed by the laparoscopic technique. Since we have started this modular training program in our department, a consecutive of 100 patients underwent laparoscopic low anterior resection and coloanal anastomosis with covering stoma. Demographics, characteristics, and postoperative outcomes were evaluated.

Results:
Surgical anatomical planes and important vascular structures/variations are both shown by 3D animation, cadaveric dissection, and laparoscopic surgery. Out of 100 consecutive cases, there were no mortality, 5 anastomotic leakages 1 of which necessitates reoperation, and 2 splenic injuries which were managed conservatively.

Conclusion:
This unique educational video module for SFM demonstrates surgical anatomical planes and important vascular structures/variations. The employment and implementation of time-independent multimedia components lead to effective training and can theoretically facilitate the learning process.
Mediastinoscopy-assisted Transhiatal Esophagectomy (MATHE) in End-stage Achalasia and Gastric Bypass: Technique and Early Results
Authors: Gergen Anna K. , Weyant Michael J. , McCarter Martin D. , Pratap Akshay 
Published: March 2021

Introduction:
Approximately 5% of patients who have undergone prior Heller myotomy and Roux en Y gastric bypass progress to end-stage achalasia (ESA). Surgical options for ESA are often limited to esophagectomy for management of severe dysphagia or life-threatening aspiration episodes. Mediastinoscopy-assisted transhiatal esophagectomy (MATHE) by a small left neck incision combined with an abdominal incision, without using a transthoracic approach, has been reported to reduce pulmonary complications. We herein present the first report of MATHE in 2 consecutive patients with ESA and gastric bypass.

Materials and Methods:
Between August 2017 and September 2020, 2 patients who had undergone Heller myotomy and Roux en Y gastric bypass underwent MATHE for ESA. Transhiatal esophagectomy with mediastinoscopy-assisted dissection was performed. The remnant stomach was used as the conduit in both cases. The embedded Supplemental Digital Content 1 (http://links.lww.com/SLE/A269) reports our novel technique.

Results:
Both cases were completed laparoscopically without conversion to laparotomy or thoracotomy. Median length of hospital stay was 9 days (range, 6 to 11 d). Postoperatively, 1 patient developed a cervical anastomotic leak, which healed with conservative management. No other major complications were observed.

Conclusions:
MATHE can be safely performed in patients with a history of gastric bypass and ESA without requiring thoracoscopic mobilization of the esophagus. Further studies are required to validate reproducibility of our technique as an alternative to using a thoracic incision.
Interference Resolution in Nonfluent Variant Primary Progressive Aphasia: Evidence From a Picture–Word Interference Task
Authors: Andreou Maria , Peristeri Eleni 
Published: March 2021

Background:
Picture–word interference tasks have been used to investigate (a) the time course of lexical access in individuals with primary progressive aphasia (PPA) and (b) how these individuals resolve competition during lexical selection.

Objective:
To investigate the time course of Greek-speaking individuals with PPA to produce grammatical gender-marked determiner phrases by examining their picture-naming latencies in the context of distractor words.

Method:
Eight individuals with nonfluent variant PPA (nfv-PPA; M age = 62.8 years) and eight cognitively intact controls (M age = 61.1 years) participated in our study. In a picture–word interference task, the study participants named depicted objects by producing determiner + noun sequences. Interference was generated by manipulating the grammatical gender of the depicted objects and distractor words. Two stimulus onset asynchronies were used: +200 ms and +400 ms.

Results:
The individuals with nfv-PPA exhibited longer picture-naming latencies than the controls (P = 0.003). The controls exhibited interference from incongruent distractors at both asynchronies (P < 0.001); the individuals with PPA exhibited interference from incongruent distractors only at the +400-ms interval (P = 0.002). The gender-congruency effect was stronger for the individuals with PPA than for the controls at the +400-ms interval (P = 0.05); the opposite pattern was observed at the +200-ms interval (P = 0.024).

Conclusion:
Gender interference resolution was abnormal in the individuals with nfv-PPA. The results point to deficits in lexicosyntactic networks that compromised the time course of picture-naming production.
Effects of morphine preconditioning on TRPV1 sensitization and ERK1/2 phosphorylation induced by TGFβ1 in neurocytes
Authors: Ma Zhen-Xiao , Wang Sheng 
Published: March 2021

Objective
Myocardium ischemia-reperfusion injury (IRI) is the major cause of cardiac dysfunction. While intrathecal morphine preconditioning (MPC) can alleviate IRI in animal model, the molecular processes underlying IRI and MPC remain elusive. This study aims to test whether pretreatment with morphine can ameliorate the increased activity of transient receptor potential vanilloid 1 (TRPV1) induced by transforming growth beta1 (TGFβ1) in cultured dorsal root ganglion neurons as a model of the effects of cardiac ischemia on nociceptive primary afferent neurons.

Methods
To simulate the effect of MPC on dorsal root ganglia (DRG) neurons during myocardial IRI in vivo, the cells were pretreated with morphine for 10 min, followed by wash-out for 30 min before TGFβ1 was added. Afterwards, DRG neurons and N2a cells in all groups were stimulated by capsaicin, and the inward current induced by capsaicin were detected by whole-cell recording on DRG neurons; the expression of TRPV1, phosphorylated (p) TRPV1, ERK1/2, and pERK1/2 were detected by western blot in N2a cells.

Results
In comparison with cells with normal culture, the inward current was enhanced of cells incubated with TGFβ1 (P < 0.05), and the relative expression of TRPV1, pTRPV1, and pERK1/2 was upregulated as well (P < 0.05); In comparison with cells incubated with TGFβ1, the inward current induced by capsaicin were decreased by pretreatment with morphine (P < 0.05), Moreover, the relative expression of TRPV1, pTRPV1, and pERK1/2 were also reduced by MPC (P < 0.05).

Conclusion
MPC inhibits TRPV1 sensitized by TGFβ1 in DRG cells, and the mechanism might be associated with the downregulation of pERK1/2 expression.
Ischemic-time associated reductions in equol monosulfate plasma levels in a mouse model of ischemic stroke: support the existence of a ‘brain–gut axis’
Authors: Kim Jung-Hoon , Lim Chiyeon , Cho Suin 
Published: March 2021

Background
Interest is growing in the role played by intestinal flora in the pathogeneses of diseases and in the possibility of treating disease by altering intestinal flora compositions. Recent studies have focused on the relationship between the intestinal microbiome and brain function as proposed by the brain–gut axis hypothesis.

Objectives
To investigate the relation between ischemic stroke and plasma equol monosulfate levels (a soy isoflavone metabolite) in a middle cerebral artery occlusion (MCAO) mouse model.

Methods
Mice (C57BL/6) were subjected to MCAO for various times (30 min to 24 h), and degrees of cerebral damage were assessed using total infarction volumes, brain edema severities and neurological deficit scores. Hematoxylin and eosin and cresyl violet staining were used to observe morphological changes in ischemic brains. Levels of equol monosulfate in plasma and the relationships between these and degree of brain injury were investigated.

Results
Infarction volumes, brain edema severity and neurological deficit scores were significantly correlated with ischemic time, and morphological deteriorations of brain neuronal cells also increased with ischemic duration. Equol monosulfate contents were ischemic-time dependently lower in MCAO treated animals than in sham-operated controls.

Conclusion
Ischemic stroke may time-dependently reduce plasma levels of equol monosulfate by lowering the metabolic rate of equol in MCAO-induced mice. This study provides indirect support of the brain–gut axis hypothesis.

Published: March 2021

AbstractVariations in the age patterns and magnitudes of excess deaths, as well as differences in population sizes and age structures make cross-national comparisons of the cumulative mortality impacts of the COVID-19 pandemic challenging. Life expectancy is a widely-used indicator that provides a clear and cross-nationally comparable picture of the population-level impacts of the pandemic on mortality. Life tables by sex were calculated for 29 countries, including most European countries, Chile, and the USA for 2015-2020. Life expectancy at birth and at age 60 for 2020 were contextualised against recent trends between 2015-19. Using decomposition techniques, we examined which specific age groups contributed to reductions in life expectancy in 2020 and to what extent reductions were attributable to official COVID-19 deaths. Life expectancy at birth declined from 2019 to 2020 in 27 out of 29 countries. Males in the USA and Lithuania experienced the largest losses in life expectancy at birth during 2020 (2.2 and 1.7 years respectively), but reductions of more than an entire year were documented in eleven countries for males, and eight among females. Reductions were mostly attributable to increased mortality above age 60 and to official COVID-19 deaths. The COVID-19 pandemic triggered significant mortality increases in 2020 of a magnitude not witnessed since WW-II in Western Europe or the breakup of the Soviet Union in Eastern Europe. Females from 15 countries and males from 10 ended up with lower life expectancy at birth in 2020 than in 2015.
Moderation effect of social support and personal resources between emotional work and employee wellbeing
Authors: Mehta Poonam , Sharma Jyoti 
Published: March 2021

PurposeThere is dearth of studies in the literature which have discussed the relevance of personal and social resources of employees to protect them from adverse impacts of emotional job demands. However, interaction effect of these two resources on wellbeing of the employees in context to emotional work is inadequate. The present study is aimed to address the existing gap and investigate the relevance of personal and social resources as moderators in the presence of each other between emotional work and employee wellbeing.Design/methodology/approachThe research work has focused on employees working on frontline profiles of civil aviation industry of north India. The responses of 720 frontline employees have been collected through pretested questionnaire. To understand the moderation effect of two variables, model number 3 developed by Hayes (2012) has been applied.FindingsThe findings have revealed that moderator role of social support between emotional work and employee wellbeing. However, research has pointed out that at high level of social support personal resources of employees' start to decline which subsequently reduces the wellbeing of employees.Research limitations/implicationsThe present research work has analysed the moderated moderation effect of personal and social resources between emotional work and employee wellbeing. Besides, the relative significance of personal resources vis-a vis social resources empirically in context of employee wellbeing in case of emotional work has also been highlighted in the work.Practical implicationsThe results of the study have suggested the employees to receive less social support from friends, family and other significant relationships to protect their personal resources in emotional work settings. Moreover, research work has implicated for employers to draw out the various interventions through which personal resources of employees can be enhanced in emotional work settings. Also, the research has assisted in designing the key competencies for different job domains of emotional work setups.Social implicationsThe present study is very substantial in offering various parameters over which wellbeing policies for individuals can be framed. Also, the study has outlined the consequences of receiving different levels of social support which is applicable for that set of population who wants to enhance their personal resources for attaining high wellbeing.Originality/valueThe study has empirically investigated interaction effect of social and personal resources of employees between emotional work and employee wellbeing which is scarce in the literature. Besides, a dark side of social support in emotional work context has also been highlighted which was scarcely discussed in emotional work settings previously.

Authors: Lawrence Eleanor T. , Tworoger Leslie , Ruppel Cynthia P. , Yurova Yuliya 
Published: March 2021

PurposeThe purpose of this study is to explore balanced leadership behaviors, which exhibit ambidexterity, in a top management team (TMT) recognized for innovation and operational success.Design/methodology/approachAn action research case study was conducted in a single global organization in an industry requiring high levels of innovation. Operationalized as a balance of exploratory and exploitative behaviors, leadership ambidexterity was measured using the strategic-operational dimension of the Leadership Versatility Index (LVI©) which when completed included 67 assessments provided by TMT peers, supervisors and direct reports. Using quantitative and qualitative data, we examined the behaviors of six executives and the degree of flexibility they exhibit when switching opposing behaviors.FindingsThis study provides empirical evidence that TMT leaders of a highly innovative company strive to flexibly move between explorative and exploitative behaviors both as individual members and as an executive team. A high degree of exploitation–exploration versatility was also linked to the TMT effective performance.Practical implicationsFor organizational practitioners, the study offers a quantifiable measure of individual and team leadership ambidexterity. It can be used to raise awareness and suggest ambidextrous behaviors to TMT leaders and “high-management-potentials”.Originality/valueThis study measures leadership ambidexterity of individual executives and the TMT as a group using a quantitative instrument supported by 360-degree qualitative data. Access to both secondary and proprietary information allowed in depth examination of the TMT behaviors in an innovative firm, which was acquired at a premium and was recognized with multiple innovation awards.

Professional parental status disclosure in intensive family intervention work
Authors: Archard Philip John 
Published: March 2021

Purpose
This paper is concerned with what intensive family intervention professionals reveal to the parents with whom they work about whether they themselves are parents or not, as a form of professional self-disclosure in child welfare work. This paper also addresses the act of lying in professional self-disclosure.

Design/methodology/approach
The paper draws on material from a series of narrative interviews completed with practitioners from one family intervention programme in an English local authority as part of a study looking at how children’s services professionals experience the suffering of parents. The study was based on a psychoanalytically informed methodological approach, which is represented in the analysis provided in the paper.

Findings
The overall team ethos regarding parental status disclosure is considered briefly first then two participants’ accounts are explored in depth. These involved, what can be considered as, questionable or unorthodox stances regarding parental status disclosure (and self-disclosure more generally). The exploration illustrates the role that practitioners’ personal lives and histories can play in influencing how the act of professional parental status disclosure is experienced and how particular positions are invested in regarding the role of self-disclosure in working relationships with parents.

Originality/value
Child welfare and family intervention professionals are often asked personal questions by the parents and carers they work with, including questions about whether they are a parent or not. These questions can be difficult to answer and there is a need for dedicated empirical analysis into the ways in which professionals experience, think about and respond to them and what they disclose about themselves when working with families.
Sprawl of the COVID-19 in changing scenario: a methodology based on social interaction
Authors: Kumar Gaurav , Kumar Akshay , Khan Farhan Mohammad , Gupta Rajiv 
Published: March 2021

PurposeThere are several methods developed in the recent past to predict the spread of COVID-19 in different countries. However, due to changing scenarios in terms of interaction among people, none could predict the case close to the actual figures. An attempt to simulate people's interaction due to economic reopening concerning the confirmed cases at various places as per changing situation has been made. The scenario development method's base lies in the hypothesis that if there were no inter-state transportation during India's lockdown after May 24th, the number of infection cases would have started lowering down in a normalized progression.Design/methodology/approachThis study has developed three scenarios from the worst to the business-as-usual to the best in order to project the COVID-19 infections in India concerning infections observed from January 30th till May 24th, 2020, since the domestic flights became operational from May 25th, 2020, in India.FindingsBased on the observed cases till May 24th, the rise of cases is projected further in a random progression and superimposed to the normal progression. The results obtained in the three scenarios present that worst case needs complete lockdown, business-as-usual case needs regulatory lockdown and best case assures complete lockdown release by the second week of September 2020. This study suggests the preparedness and mitigation strategy for a threefold lockdown management scheme in all-inclusive.Originality/valueThe work has been done on a hypothesis which is solely original.
