Impact of Psychological Aggression at the Workplace on Employees’ Health: A Systematic Review of Personal Outcomes and Prevention Strategies
Authors: Pacheco Emelda C. R. L. , Bártolo Ana , Rodrigues Fabiana , Pereira Anabela , Duarte João C. , Silva Carlos F.
Published: March 2021

Psychological aggression perpetrated by customers, coworkers, and supervisors is a behavior frequently experienced in the workplace with negative consequences for an individual’s health. The aim of this systematic review was to examine the personal outcomes of overt workplace psychological aggression and summarize empirical evidence on how to prevent and reduce its effects. A search on PubMed, Scopus, ProQuest, and Web of Science electronic databases was made. Data were obtained from 30 studies (26 cross-sectional, 3 longitudinal, 1 quasi-experimental) representing 20,683 employees. Longitudinal studies indicated that workplace psychological aggression is significantly associated with musculoskeletal injury and psychological strains (anxiety, depression, anger) over time. Research also suggests that psychological aggression at work predicts fear, emotional exhaustion, depersonalization, personal accomplishment, and physical symptoms, for example. Additionally, the information collected suggested that support from coworkers, supervisors, and management; informational support; political skills; job resources; and confidence to prevent and respond to aggression moderate significantly the impact of workplace psychological aggression on personal and organizational outcomes. Perceptions of a violence-prevention climate, aggression-preventive supervisor behavior, and aggression-preventive employee effort are also significantly associated with a reduction in psychological aggression at work and strains. In conclusion, this review allows us to understand the effects of the psychological aggression by identifying the preventive strategies that could be adopted by managers, supervisors, or leaders to deal with it and promote individual’s health in the workplace.
Identification of the 11-lncRNA signatures associated with the prognosis of endometrial carcinoma
Authors: Wan Jing , Chen Peigen , Zhang Yu , Ding Jie , Yang Yuebo , Li Xiaomao
Published: March 2021

Endometrial carcinoma (EC) is the fourth most common cancer in women. Some long non-coding RNAs (lncRNAs) are regarded as potential prognostic biomarkers or targets for treatment of many types of cancers. We aim to screen prognostic-related lncRNAs and build a possible lncRNA signature which can effectively predict the survival of patients with EC. We obtained lncRNA expression profiling from the TCGA database. The patients were classified into training set and verification set. By performing Univariate Cox regression model, Robust likelihood-based survival analysis, and Cox proportional hazards model, we developed a risk score with the Cox co-efﬁcient of individual lncRNAs in the training set. The optimum cut-off point was selected by ROC analysis. Patients were effectively divided into high-risk group and low-risk group according to the risk score. The OS of the low-risk patients was significantly prolonged compared with that of the high-risk group. At last, we validated this 11-lncRNA signature in the verification set and the complete set. We identified an 11-lncRNA expression signature with high stability and feasibility, which can predict the survival of patients with EC. These findings provide new potential biomarkers to improve the accuracy of prognosis prediction of EC.
Herder Publishers and the Second Vatican Council
Authors: O’Collins Gerald
Published: March 2021

This article examines the contribution made by the publishing house of Herder to the reception of the teaching and decisions of Vatican II (1962–1965). This input began with the five volumes of Commentary on the Documents of Vatican II (German original 1966–1968), edited by Herbert Vorgrimler and including contributions from twenty-one authors who had played roles in drafting the Council’s sixteen documents and could expound from the inside the authorial intentions ( intentio auctoris) of these texts. The subsequent five volumes of the Herders Theologischer Kommentar (2004–2009), edited by Peter Hünermann, could also explore the post-Vatican II history of interpretation and implementation of the conciliar texts (the intentio textus) and the insights of readers with their different questions and expectations (the intentio legentis).
“Like Yeast in Dough”: The Church–World Relationship in the Evolving Thought of Marie-Dominique Chenu
Authors: Kate Holman Mary
Published: March 2021

During his Parisian “exile” from 1942 to 1954, Marie-Dominique Chenu’s experiences with worker communities transformed his vision of the church–world relationship. This article highlights the overlooked social dimension of Chenu’s pre-conciliar thought, tracing his shift from a “New Christendom” ecclesiology towards a church in a state of mission and his growing call for ecclesial structural change in light of changing social structures. These life experiences would lead him to advocate for a church that reads and responds to the “signs of times.”
The Contribution of Francis A. Sullivan, SJ to a Deeper Understanding of Charisms in the Church
Authors: Stayne John
Published: March 2021

Francis A. Sullivan, SJ made a number of significant contributions to the Catholic theology of charism. Through an accepted emendation, he helped write Lumen Gentium 12; he investigated the new movement of “Catholic Pentecostals” for the Congregation for the Doctrine of the Faith; he later produced a number of related academic works exploring the nature of the charisms and their role in ecclesiology. This article argues that Sullivan’s reading of the division in Lumen Gentium 4 between charismatic and hierarchical gifts, and how he uses this division to argue that sacramental ordained ministry should presume prior charismatic gifts, has the capacity to support a re-conceptualization of ecclesial ministry.
Historical Crucifixion: A Liberationist Response to Deep Incarnation
Authors: Lee Michael E.
Published: March 2021

In light of the social-ecological crisis facing Puerto Rico, this article offers a response to deep incarnation theologies. Though it notes that deep incarnation offers a helpful account of divine presence and solidarity with all suffering creatures, the essay draws from liberationist theologians to argue that equating the cross with evolutionary death obscures the sinful causes of crucifixion. Ultimately, the essay insists that the notion of deep incarnation that addresses evolutionary suffering must be linked to a similarly “deep” notion of crucifixion rooted in historical reality.
Reflections on Satyagraha in Today’s India
Authors: Patkar Medha
Published: March 2021

Following Mahatma Gandhi is inspiring. But at the same time, it also brings certain feelings of guilt because one needs to follow not only his politics but also his ethics and thinking. Today neither Gandhi nor Gandhism has survived, not in our economy, not in our politics and certainly not in our society. Still, in the little things that surround us, somehow the idea of Gandhi remains alive. People who belong to the dalit, adivasi communities, farmers and labourers from the unorganised sector have shown their courage, commitment and confidence to fight their battles and continue their understanding of satyagraha and Gandhi. But times are changing. Casteism and communalism are now compelling everyone to fight a new freedom movement. What kind of satyagraha is needed to deal with these concerns? One effective way is through non-party people’s movements that necessarily define and re-define their own politics. These mass organisations have to challenge themselves to deal with the reality of not only casteism and communalism, but also that of the current development paradigm. Our next step is also to minimise consumerism to save nature, people and their livelihood.
Trauma-Informed Interventions for At-Risk and Justice-Involved Youth: A Meta-Analysis
Authors: Olaghere Ajima , Wilson David B. , Kimbrell Catherine S.
Published: March 2021

The impact of trauma on children and youth has potentially serious and long-lasting negative consequences, including increased involvement in the juvenile and criminal justice systems. The objective of this study was to meta-analyze research on the effectiveness of trauma-informed treatment programs for justice-involved youth and youth at risk of justice system involvement who have experienced some form of trauma. Our systematic search identified 29 publications that met our eligibility criteria and represent 30 treatment–comparison contrasts. Six of these evaluated the effectiveness of trauma-informed programs for justice-involved youth, and the remaining 24 evaluated programs for at-risk children and youth. The findings suggest that cognitive-behavioral therapy (CBT), including trauma-focused CBT, is effective. In addition, there was weak evidence suggesting that programs that used a cognitive restructuring component or had the participant create a trauma narrative were slightly more effective than programs without these features. Additional high-quality randomized controlled trials are needed.
The Precariousness of Immaterial Labor: Self-Taylorization in the Brazilian Software Industry
Authors: Amorim Henrique , Reis Grazia Mauricio
Published: March 2021

Contrary to theses that present the emergence of immaterial and digital labor as a paradigmatic break with industrial production, analysis of the “agile methodologies” employed in software production suggests that the “new” features of these forms of labor organization in the twenty-first century are configured as adaptations of Taylor-Fordism and Toyotism to a new productive frontier unexplored or explored to a limited extent by capital in the nineteenth and twentieth centuries, especially in that the self-Taylorization of labor is one of the bases of software production in Brazil.
Giant Fibrovascular Polyp as an Unusual Cause of Globus Pharyngeus
Authors: Sotirović Jelena , Pavićević Ljubomir , Petrović Stanko , Ristić Saša , Perić Aleksandar
Published: March 2021

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.
Are Breaks Better? A Comparison of Breaks Are Better to Check-In Check-Out
Authors: Majeika Caitlyn E. , Wehby Joseph H. , Hancock Eleanor M.
Published: March 2021

Identification and validation of effective Tier 2 interventions that address a wide range of student-level factors is critical to the sustainability of positive behavior interventions and supports (PBIS). Within the context of Check-in Check-out (CICO), function of behavior affects outcomes for many students, especially for those who engage in problem behavior to escape from tasks. Therefore, more research is needed to understand if and how we can support students with escape-maintained behavior. Breaks are Better (BrB) is a modified version of CICO that includes a system for taking breaks. The current research on BrB is limited but promising. The purpose of this study was to compare the effectiveness of CICO to BrB. Using a multitreatment design, we compared the effects of each intervention by measuring problem behavior and academic engagement across five elementary students who engaged in problem behavior to escape from tasks. Overall results were mixed and ranged from strong effects of BrB to no differential effects. However, despite the results, teachers and students consistently rated BrB as being a more preferable intervention. We conclude with limitations and implications for practice.
The use of Facebook in romantic relationships: An actor-partner interdependence mediation model predicting relationship visibility
Authors: Bouchard Geneviève , Harrigan Isabelle , Tobin Stephanie J.
Published: March 2021

The purpose of this paper was to document the use of social media in romantic relationships. More specifically, we examined whether the information that people desired to share (i.e., desired relationship visibility) and shared in practice (i.e., actual relationship visibility) about their romantic relationships on Facebook was predicted by their level of relational commitment. A sample of 139 couples, users of Facebook, aged 17 to 30 years, participated in the study. Participants completed questionnaires and used the Friendship application on Facebook (which gathered data directly from their Facebook accounts). The mediating role of desired relationship visibility in the link between relational commitment and actual relationship visibility on Facebook (i.e., declared relationship status and transient relationship visibility) was investigated using path analyses for dyadic data. Results of actor-partner interdependence mediation model analyses confirmed that women’s relational commitment was positively associated with their desired relationship visibility on Facebook. Men’s and women’s desired relationship visibility were, in turn, associated with their own and their partner’s declared relationship status and their own transient relationship visibility on Facebook. Our results provided evidence of the dyadic nature of Facebook self-presentations of coupledom.

Published: March 2021

Background:

Studies comparing end-of-life care between patients who are high cost users of the healthcare system compared to those who are not are lacking.

Aim:

The objective of this study was to describe and measure the association between high cost user status and several health services outcomes for all adults in Canada who died in acute care, compared to non-high cost users and those without prior healthcare use.

Settings and participants:

We used administrative data for all adults who died in hospital in Canada between 2011 and 2015 to measure the odds of admission to the intensive care unit (ICU), receipt of invasive interventions, major surgery, and receipt of palliative care during the hospitalization in which the patient died. High cost users were defined as those in the top 10% of acute healthcare costs in the year prior to a person’s hospitalization in which they died.

Results:

Among 252,648 people who died in hospital, 25,264 were high cost users (10%), 112,506 were non-high cost users (44.5%) and 114,878 had no prior acute care use (45.5%). After adjustment for age and sex, high cost user status was associated with a 14% increased odds of receiving an invasive intervention, a 15% increased odds of having major surgery, and an 8% lower odds of receiving palliative care compared to non-high cost users, but opposite when compared to patients without prior healthcare use.

Conclusions:

Many patients receive aggressive elements of end-of-life care during the hospitalization in which they die and a substantial number do not receive palliative care. Understanding how this care differs between those who were previously high- and non-high cost users may provide an opportunity to improve end of life care for whom better care planning and provision ought to be an equal priority.
BAIT: A New Medical Decision Support Technology Based on Discrete Choice Theory
Authors: ten Broeke Annebel , Hulscher Jan , Heyning Nicolaas , Kooi Elisabeth , Chorus Caspar
Published: March 2021

We present a novel way to codify medical expertise and to make it available to support medical decision making. Our approach is based on econometric techniques (known as conjoint analysis or discrete choice theory) developed to analyze and forecast consumer or patient behavior; we reconceptualize these techniques and put them to use to generate an explainable, tractable decision support system for medical experts. The approach works as follows: using choice experiments containing systematically composed hypothetical choice scenarios, we collect a set of expert decisions. Then we use those decisions to estimate the weights that experts implicitly assign to various decision factors. The resulting choice model is able to generate a probabilistic assessment for real-life decision situations, in combination with an explanation of which factors led to the assessment. The approach has several advantages, but also potential limitations, compared to rule-based methods and machine learning techniques. We illustrate the choice model approach to support medical decision making by applying it in the context of the difficult choice to proceed to surgery v. comfort care for a critically ill neonate.
Potential Effectiveness of Bicycle-Automatic Emergency Braking using the Washtenaw Area Transportation Study Data Set
Authors: Haus Samantha H. , Anderson Ryan M. , Sherony Rini , Gabler Hampton C.
Published: March 2021

In the United States, fatalities from vehicle–bicycle crashes have been increasing since 2010. A total of 857 cyclists were struck and killed in 2018 which is an increase from 623 fatalities in 2010. One promising countermeasure is Automatic Emergency Braking (AEB), which can help prevent and/or mitigate many vehicle–bicycle crashes. AEB is a vehicle-based system that can detect and mitigate an impending crash. The goal of this study was to elucidate U.S. vehicle–bicycle crashes and examine related factors to estimate AEB effectiveness. This study used a unique in-depth vehicle–bicycle crash study dataset collected under the collaboration of the Washtenaw Area Transportation Study (WATS) and the Toyota Collaborative Research Center conducted in southeast Michigan from 2011 to 2013. The WATS database provides in-depth investigations of vehicle–bicycle crashes in the United States. The characteristics of the WATS vehicle–bicycle crashes were validated against the Fatality Analysis Reporting System and the General Estimate System. The WATS database cases were examined to estimate the potential effectiveness of AEB to prevent or mitigate vehicle–bicycle collisions. In 60% of the WATS cases, cyclists were in the road for more than 1 s before impact. Assuming that a hypothetical AEB system requires a minimum of 1 s for detection and brake activation, these collisions would potentially be avoided or mitigated. However, for the remaining cases with less than 1 s of time to react (40% of cases), that AEB system would be challenged to avoid or mitigate the collision.
Review of Methods for Estimating Construction Work Zone Capacity
Authors: Mashhadi Ali H. , Farhadmanesh Mohammad , Rashidi Abbas , Marković Nikola
Published: March 2021

Road reconstruction and the resulting work zones are considered as a major source of traffic congestion and delays on freeways. The roadway capacity is decreased as a result of a reduced number of traffic lanes, narrower lanes, and work zone speed limits. Accurate prediction of construction work zone capacity helps traffic engineers to have a better estimation of the traffic flow characteristics. To this end, multiple methodologies have been developed to quantify the impacts of work zones on traffic flow. This paper presents a critical review of the three types of approaches to estimating construction work zone capacities, including parametric, non-parametric, and simulation. Then the most commonly considered factors and their frequency are presented. It also performs a detailed review of the approaches, their objectives, and weaknesses. Lastly, it provides recommendations for future research. The presented work could help researchers in the area of work zone capacity estimation by presenting all the previous methodologies in one place.
Measuring the Regional Economic Impact of Transportation Access Improvements in the Context of a Large Metropolitan Region
Authors: Weisbrod Glen , Goldberg Jenna , Frank Parry
Published: March 2021

Transportation planners are increasingly recognizing the importance of access in enabling employment growth and better paying job opportunities for residents. Although regional economic impact analysis is often an important element of transportation investment evaluation by state departments of transportation, it can be particularly challenging for metropolitan area planners because existing economic modeling methods do not fully account for the multifaceted roles that transportation links play in affecting access within large, polycentric metropolitan areas. This article examines these issues and presents information from a study of the Chicago region, to evaluate statistical relationships of employment cluster size and wage levels to zonal differences in business-to-business connectivity and population connectivity. It presents elasticities of employment and wage impact associated with various access measures for different sectors of the economy. These findings point to the importance of transportation planners considering the impacts on connectivity to both population markets and employment centers when evaluating the potential economic implications of proposed transportation system improvements in large, polycentric metropolitan areas. The article then lays out directions for future research and practice to improve transportation project evaluation and planning.
Understanding Urban Commercial Vehicle Driver Behaviors and Decision Making

Published: March 2021

As e-commerce and urban deliveries spike, cities grapple with managing urban freight more actively. To manage urban deliveries effectively, city planners and policy makers need to better understand driver behaviors and the challenges they experience in making deliveries. In this study, we collected data on commercial vehicle (CV) driver behaviors by performing ridealongs with various logistics carriers. Ridealongs were performed in Seattle, Washington, covering a range of vehicles (cars, vans, and trucks), goods (parcels, mail, beverages, and printed materials), and customer types (residential, office, large and small retail). Observers collected qualitative observations and quantitative data on trip and dwell times, while also tracking vehicles with global positioning system devices. The results showed that, on average, urban CVs spent 80% of their daily operating time parked. The study also found that, unlike the common belief, drivers (especially those operating heavier vehicles) parked in authorized parking locations, with only less than 5% of stops occurring in the travel lane. Dwell times associated with authorized parking locations were significantly longer than those of other parking locations, and mail and heavy goods deliveries generally had longer dwell times. We also identified three main criteria CV drivers used for choosing a parking location: avoiding unsafe maneuvers, minimizing conflicts with other users of the road, and competition with other commercial drivers. The results provide estimates for trip times, dwell times, and parking choice types, as well as insights into why those decisions are made and the factors affecting driver choices.
Spatio-Temporal Influence of Extreme Weather on a Taxi Market
Authors: Wong R. C. P. , Mak P. L. , Szeto W. Y. , Yang W. H.
Published: March 2021

Extreme weather conditions, strong gusts, and torrential rainfall threaten the safety of the general public and restrict people’s travel options. Most of the transportation modes are suspended because of safety reasons. Taxis are one of the only few available non-private transport modes to provide services to those who have urgent and unavoidable travel needs. This study uses global positioning system data collected from 460 Hong Kong urban taxis during nine ordinary and one tropical cyclone periods aiming to find out and explain the differences in relation to the percentage of taxis not in operation, the number of served passenger-trips, average time spent by vacant-taxi drivers finding a customer, and the percentage of taxi drivers in cross-district customer-search throughout the same 48 h duration. The findings show an inadequate level of taxi supply and a high passenger demand during the tropical-cyclone-affected period. Up to 80% of taxis were not in operation to serve the urgent and necessary trips. The average customer-search time for taxi drivers, which is anticipated inversely proportional to the demand for taxi rides, was very short (about 5 min). Policy measures are discussed and recommended to the government to improve the taxi services during extreme weather conditions.
Dangerous minds in dangerous times
Authors: Beiner Ronald
Published: March 2021

Friedrich Nietzsche and Martin Heidegger hold firmly entrenched places within the canon of modern philosophy. And rightly so: both are penetrating critics of liberal modernity. Yet we need to ask ourselves whether, as academics teaching these thinkers, we are doing full justice to the more disturbing aspects of their thought. They don’t simply interrogate the axioms of modern life as a subject for intellectual reflection; they have a praxis-oriented project to demolish the post-1789 moral-political dispensation that we tend to take for granted and replace it with a new radically illiberal and anti-egalitarian dispensation. The task of reconsidering the perils of going too easy on these thinkers, or giving them the benefit of the doubt, is made more urgent by the apparent return of fascist or ‘fascoid’ modes of politics, and in particular, the emergence of a far-right intelligentsia all too keen to appropriate these thinkers for far-right purposes.
Modeling Long-Term Housing Recovery after Technological Disaster Using a Virtual Audit with Repeated Photography
Authors: Hendricks Marccus D. , Meyer Michelle Annette
Published: March 2021

Many communities face risks of technological disasters at fertilizer plants and other facilities. Understanding damage and rebuilding of housing supports planners in implementing policies that will enable recovery. Using repeat photography, this study audited housing rebuilding in West, Texas for three years following an explosion. Photos were combined with appraisal data to understand variation in rebuilding across parcels. Results indicate that rebuilding slows dramatically after year 1, leaving many parcels vacant three years post-disaster. Parcels with higher pre-disaster values were more likely to be completely rebuilt. Planners need targeted programming to support rebuilding of lower-value homes and address vacancies.
Canadian Society of Thoracic Radiology/Canadian Association of Radiologists Clinical Practice Guidance for Non-Vascular Thoracic MRI

Published: March 2021

Historically thoracic MRI has been limited by the lower proton density of lung parenchyma, cardiac and respiratory motion artifacts and long acquisition times. Recent technological advancements in MR hardware systems and improvement in MR pulse sequences have helped overcome these limitations and expand clinical opportunities for non-vascular thoracic MRI. Non-vascular thoracic MRI has been established as a problem-solving imaging modality for characterization of thymic, mediastinal, pleural chest wall and superior sulcus tumors and for detection of endometriosis. It is increasingly recognized as a powerful imaging tool for detection and characterization of lung nodules and for assessment of lung cancer staging. The lack of ionizing radiation makes thoracic MRI an invaluable imaging modality for young patients, pregnancy and for frequent serial follow-up imaging. Lack of familiarity and exposure to non-vascular thoracic MRI and lack of consistency in existing MRI protocols have called for clinical practice guidance. The purpose of this guide, which was developed by the Canadian Society of Thoracic Radiology and endorsed by the Canadian Association of Radiologists, is to familiarize radiologists, other interested clinicians and MR technologists with common and less common clinical indications for non-vascular thoracic MRI, discuss the fundamental imaging findings and focus on basic and more advanced MRI sequences tailored to specific clinical questions.
Independent wheel control system design for highly automated driving
Authors: Li Shihuan , Wang Lei
Published: March 2021

For L4 and above autonomous driving levels, the automatic control system has been redundantly designed, and a new steering control method based on brake has been proposed; a new dual-track model has been established through multiple driving tests. The axle part of the model was improved, the accuracy of the transfer function of the model was verified again through acceleration-slide tests; a controller based on interference measurement was designed on the basis of the model, and the relationships between the controller parameters was discussed. Through the linearization of the controller, the robustness of uncertain automobile parameters is discussed; the control scheme is tested and verified through group driving test, and the results prove that the accuracy and precision of the controller meet the requirements, the robustness stability is good. Moreover, the predicted value of the model fits well with the actual observation value, the proposal of this method provides a new idea for avoiding car out of control.
Computation of passive suspension parameters for improvement of vehicle ride quality based on stochastic optimal controller with a look-ahead preview
Authors: Satyanarayana VSV , Gopala Rao LVV , Sateesh B , Mohan Rao N
Published: March 2021

This article aims to determine the optimum parameters of a half-car model passive suspension vehicle passing on a random road. The optimum parameters are obtained based on the response of linear quadratic regulator control with a look-ahead preview for attaining the passive suspension performance nearly equivalent to the active suspension performance. The optimum parameters are estimated by equalizing mean square suspension controlling forces of passive and active vehicle models and subsequently minimizing the performance error between the two systems. The response of passive suspension with optimized parameters matches approximately with the active suspension response, with respect to ride comfort and road holding.
Recognition of cutting rock hardness by hydraulic cylinder pressure
Authors: He Ying , Tian Muqin , Feng Junling
Published: March 2021

The online identification of rock hardness is the basis to adjust the rotation velocity and swing velocity of cutting head in real time. To effectively identify the hardness of rock around roadway under different cutting conditions, a novel method based on the hydraulic cylinder pressure signal is proposed. Here, we analyze the changing rule of cutting head load under different rock hardness through dynamic simulation, and the transfer characteristics between cutting dynamic load and the hydraulic cylinder pressure. On this basis, a function model between the hydraulic cylinder pressure and the protodyakonov scale of rock hardness is constructed to identify the rock hardness. The average recognition accuracy of the heavy-duty roadheader in the test is 92.01%. The experimental results indicate that the model can effectively identify the rock hardness under different cutting conditions. This study can be used for online identification of rock hardness and provide reliable basis for the automatic control of roadheader.

Published: March 2021

Recently, transplantation of cryopreserved ovarian tissue is the method for fertility preservation for oncologic and nononcologic reasons. The main challenge of ovarian cryopreservation followed by transplantation is that ischemia reperfusion injury (IRI) induced the loss of follicles. The aim of this study was to evaluate the effects of glutathione (GSH), ulinastatin (UTI) or both (GSH+UTI) on preventing ischemia reperfusion-induced follicles depletion in ovarian grafts.

Ovarian fragments were collected from 20 women aged 29±6 years. Frozen-thawed human ovarian tissue was xenografted into SCID mice, at the same time GSH, UTI and GSH+UTI was administrated respectively. The ovarian grafts were collected at the 1st, 3rd, 7th, 14th, 28th, 56th, and 85th day after xenotransplantation. Follicle survival rate was measured by H&E staining and Live/Dead staining. Angiogenic activity and macrophage recruitment was evidenced by immunohistochemical staining. The oxidative stress and inflammatory cytokines in human ovarian xenografts were measured by real-time PCR. The results indicated that after the treatments of GSH, UTI and GSH+UTI in the hosts, follicular survival in ovarian grafts were improved. The level of VEGF, CD31, and antioxidant enzymes superoxide dismutase 1 and superoxide dismutase 2 in ovarian grafts were increased. Accumulation of macrophages, level of IL6 and TNF-α, as well as malondialdehyde was decreased in ovarian grafts from treated groups. In conclusion, administration of GSH, UTI and GSH+UTI decreased the depletion of follicles in human grafts post-transplantation by inhibiting IRI-induced antiangiogenesis, oxidative stress and inflammation.

The Use of Spatial Metrics and Population Data in Mapping the Rural-Urban Transition and Exploring Models of Urban Growth in Hanoi, Vietnam
Authors: Nong Duong H. , Fox Jefferson M. , Saksena Sumeet , Lepczyk Christopher A.
Published: March 2021

The process by which cities (or urban areas) expand over time has remained a key focus for geographers, ecologists and other scientists interested in urban phenomena for decades. This study investigated the use of spatial metrics and population data for defining and mapping rural-urban transition zones in Hanoi and exploring urban growth models. The analysis showed that in 2010, about 30% of communes within Hanoi could be defined as rural, 38% as peri-urban and 32% as urban. The peri-urban communes showed a greater level of landscape fragmentation and a higher pace of population growth than rural communes. The urban landscape of Hanoi in 2010 shows characteristics of both transportation corridors and dispersed sites models—the two least eco-friendly models of urbanization. This study provides an effective method for mapping such rural-urban transition and identifies forms of urbanization in places where other socio-economic data sources are limited. This is particularly useful for planners and development agencies that require reliable methods for collecting and analysing data, which can enable them to assess variables along the rural-to-urban continuum.
Strategic Persistence in Family Business
Authors: Fang Hanqing “Chevy” , Chrisman James J. , Holt Daniel T.
Published: March 2021

Using a behavioral theory framework, we argue that family firms are more persistent (less likely to engage in the strategic renewal form of corporate entrepreneurship) in their strategic behaviors over time than nonfamily firms owing to their goals of maintaining family tradition and parsimony. We also argue that family firms controlled by founders or having a family member as Chairman or CEO are more likely to be persistent in their strategies than family firms with different governance structures. Panel regression based on a sample of 8,748 firm-year observations of S&P 1500 manufacturing firms from 1996 to 2013 support our hypotheses.

Peripheral artery disease (PAD) is a common disease affecting over 200 million people worldwide. PAD is associated with significant limb and cardiovascular morbidity and mortality which is reduced by antiplatelet and antithrombotic therapy. However, the optimal type, dose, and time of antithrombotic therapy is still uncertain.We searched 4 electronic databases from January 1, 1990, to June 1, 2020, for randomized controlled trials of patients who received oral anticoagulant and antiplatelet therapy for PAD. The primary outcome was a composite of acute limb ischemia, major amputation, myocardial infarction, ischemic stroke, death from cardiovascular events, or death from any cause. Secondary outcomes included major bleeding, fatal bleeding, and intracranial hemorrhage events.We identified 3 studies that satisfied inclusion and exclusion criteria. Compared with antiplatelet alone, oral anticoagulant plus antiplatelet therapy improved acute limb ischemia (p < 0.00001), stroke (p = 0.005), and major amputation events (p = 0.11). However, oral anticoagulant plus antiplatelet therapy was not effective for prevention of myocardial infarction (p = 0.23), death from cardiovascular events (p = 0.65), or death from any cause (p = 0.66). Additionally, a significant increase in major bleeding events was demonstrated (p < 0.00001). There was no significant difference in fatal bleeding (p = 0.16) or intracranial hemorrhage events (p = 0.43). This meta-analysis showed that oral anticoagulant plus antiplatelet therapy for PAD may improve acute limb ischemia and major amputation or stroke risk compared with antiplatelet therapy alone, but could increase the risk of major bleeding events. On the other hand, measuring myocardial infarction, death, fatal bleeding, or intracranial hemorrhage risk remains controversial.
On a new class of non-Gaussian molecular-based constitutive models with limiting chain extensibility for incompressible rubber-like materials
Authors: Anssari-Benam Afshin
Published: March 2021

In constitutive modelling of rubber-like materials, the strain-hardening effect at large deformations has traditionally been captured successfully by non-Gaussian statistical molecular-based models involving the inverse Langevin function, as well as the phenomenological limiting chain extensibility models. A new model proposed by Anssari-Benam and Bucchi ( Int. J. Non Linear Mech. 2021; 128; 103626. DOI: 10.1016/j.ijnonlinmec.2020.103626), however, has both a direct molecular structural basis and the functional simplicity of the limiting chain extensibility models. Therefore, this model enjoys the benefits of both approaches: mathematical versatility, structural objectivity of the model parameters, and preserving the physical features of the network deformation such as the singularity point. In this paper we present a systematic approach to constructing the general class of this type of model. It will be shown that the response function of this class of models is defined as the [1/1] rational function of [Formula: see text], the first principal invariant of the Cauchy–Green deformation tensor. It will be further demonstrated that the model by Anssari-Benam and Bucchi is a special case within this class as a rounded [3/2] Padé approximant in [Formula: see text] (the chain stretch) of the inverse Langevin function. A similar approach for devising a general [Formula: see text] term as an adjunct to the [Formula: see text] part of the model will also be presented, for applications where the addition of an [Formula: see text] term to the strain energy function improves the fits or is otherwise required. It is concluded that compared with the Gent model, which is a [0/1] rational approximation in [Formula: see text] and has no direct connection to Padé approximations of any order in [Formula: see text], the presented new class of the molecular-based limiting chain extensibility models in general, and the proposed model by Anssari-Benam and Bucchi in specific, are more accurate representations for modelling the strain-hardening behaviour of rubber-like materials in large deformations.

Introduction:

The dexamethasone (DEX) implant is an FDA approved treatment for diabetic macular edema, non-infectious posterior uveitis, and macular edema secondary to branch or central retinal vein occlusions. We describe a case of anterior chamber (AC) migration of a DEX implant in a patient with a history of congenital glaucoma and perform a review of the literature on this particular complication, summarizing the common risk factors, subsequent complications, and management options.

Case description:

A 46-year-old female with a history of congenital glaucoma, status post cataract extraction with insertion of intraocular lens, pars plana vitrectomy, and Baerveldt tube implant in the left eye was referred for post-operative cystoid macular edema (CME). The patient underwent insertion of a DEX implant, resulting in improvement in her CME. After the fourth implant was injected, the patient noticed a white line in her eye while looking in the mirror after doing jumping jacks. Slit lamp examination confirmed migration of the implant into the AC. Ultimately, the patient was taken to the operating room, where her implant was removed via bimanual vitrectomy through an anterior approach.

Conclusion:

This case report and literature review explores the ophthalmic structural changes specific to congenital glaucoma which may have predisposed this eye to anterior migration of the DEX implant. The purpose of this review is to detail the anatomic changes that may increase the risk of anterior chamber implant migration in patients with congenital glaucoma so that physicians may be aware of these risks when selecting patients for this implant.

Introduction:

Vitrectomy may improve visual acuity of hereditary transthyretin amyloidosis (ATTRv) patients presenting with vitreous opacities but is associated with severe complications. The objective of this study is to report visual outcomes, early and late complications of a series of ATTRv patients who underwent vitrectomy in the French ATTRv reference center.

Methods:

This retrospective, single-center study, included all ATTRv patients who underwent vitrectomy between 2002 and 2017. Data were collected on pre and postoperative best corrected visual acuity (BCVA) and early and late postoperative complications.

Results:

A total of 21 eyes from 15 patients were included. The mean postoperative follow-up was 40 ± 20 months (6–160 months). BCVA increased from 0.7 ± 0.4 LogMAR preoperatively to 0.3 ± 0.4 LogMAR ( p = 0.003) at last postoperative visit. During follow-up, all initially glaucomatous eyes worsened, with three eyes (37%) requiring filtering surgery and two eyes (25%) had further vision loss. Among non-glaucomatous patients, four eyes (31%) developed glaucoma with two requiring trabeculectomy and one eye (8%) had further vision loss. Three eyes (three patients) presented with complications of amyloid angiopathy. Three eyes (three patients) experienced recurrence of vitreous deposits requiring surgical revision.

Conclusion:

Due to the potential complications, vitrectomy in ATTRv requires specific perioperative management and life-long postoperative monitoring.

Introduction:

Ocular symptoms are uncommon manifestations of coronavirus disease 2019 (COVID-19) infection. Earlier study reported that dry eye, blurred vision, foreign body sensation, tearing, itching, conjunctival secretion, conjunctival congestion, ocular pain, and photophobia are among the ocular symptoms that could be found in COVID-19 patients. However, there are only a few reports available regarding corneal involvement in this disease. Here we report a case of keratoconjunctivitis as the only symptom of COVID-19 infection.

Case description:

A 27-year-old man who worked as an obstetrics and gynecology resident came to the outpatient clinic with the chief complaints of eye discomfort, foreign body sensation, conjunctival hyperemia, lacrimation, and photophobia in his right eye for the past 3 weeks. Fluorescence test showed a small corneal lesion. The patient was then diagnosed with keratoconjunctivitis. A week after the treatment, all symptoms were resolved. A month later, the patient came to the emergency room with the same eye complaints but with a more severe pain. The fluorescence test showed wider corneal lesion compared to last month. The result from the corneal swab is negative for bacterial or fungal infection, indicating a viral infection. Afterwards, reverse transcriptase polymerase chain reaction test from nasopharyngeal swab was performed and revealed that the patient was positive for COVID-19.

Conclusions:

This case report showed that keratoconjunctivitis may occur as the only manifestation of COVID-19 infection. Thus, patient presented with unexplainable eye symptoms should be evaluated for COVID-19 infection.
