Introduction

Thoracic endovascular aortic repair (TEVAR) has become an accepted treatment for thoracic aortic disease. However, the principal complications relate to coverage of the thoracic aortic wall and deliberate occlusion of aortic branches over a potentially long segment. Complications include risk of stroke, spinal cord ischaemia (SCI) and arterial insufficiency to the left arm (left arm ischaemia (LAI)). This study specifically scrutinised the development of SCI and LAI after TEVAR for interventions for thoracic aortic disease from 1999 to 2020. In particular, those who underwent extra-anatomical bypass (both immediate and late) were compared to the length of thoracic aortic coverage by the stent graft.

Materials and methods

Ninety-eight patients underwent TEVAR. The presenting symptoms, pathology, procedural and follow-up data were collected prospectively with particular evidence of stroke, SCI and LAI both immediate onset and after 48 h of graft placement.

Results

Fifty underwent TEVAR for an aneurysm (thoracoabdominal aortic aneurysm), 22 for dissection, 19 for acute transection and 7 for intramural haematoma/pseudoaneurysm of the thoracic aorta. Twenty-nine (30%) required a debranching procedure to increase the proximal landing zone (1 aorto-carotid subclavian bypass, 10 carotid/carotid subclavian bypass and 18 carotid/subclavian bypass). Ten patients (10%) died within 30 days of TEVAR. Twenty-four grafts covered the left subclavian artery origin without a carotid/subclavian bypass. Five required a delayed carotid/subclavian bypass for LAI (4) and SCI (1). Six developed immediate signs of SCI after TEVAR and these 11 (group i) had a mean (SD) length of coverage of the thoracic aorta of 30.2 (10.6) cm compared to 21.5 (11.2) cm (group g) in those who had no LAI or SCI post TEVAR, p < 0.05.

Conclusions

In this series, delayed carotid/subclavian bypass may be required for chronic arm ischaemia and less so for SCI. The length of coverage of thoracic aorta during TEVAR is a factor in the development of delayed SCI and LAI occurrence. Carotid subclavian bypass is required for certain patients undergoing TEVAR (particularly if greater than 20 cm of thoracic aorta is covered).
The Will of the Gods: Patterns of Dream Interpretation in Early Tamil Literature
Authors: Gunasekaran S.
Published: April 2021

Societies interpreted their dreams in various ways. While dream interpretation has always been an essential part of medical and philosophical discourse, it was only recently that historians began to show certain interest in writing what is called the cultural history of dream interpretation. In fact, dreams, rituals, myths, social memories and consciously constructed histories all share certain similarities since they engage with the past and are expressed in a narrative form. Dream psychology, therefore, may provide a useful analytical tool for historians who are interested in mapping the mental structure of societies. This article is an attempt to unearth the patterns of dream interpretations by analysing the dream expressions found in Tamil literature up to the twelfth century ad. The social attitude towards dreams in the Sangam literature, early Tamil epics and Bhakti literatures is studied in the sociocultural context of their times. One can presume that the literary language of dreams more or less reflected the contemporary cultural beliefs and social practices.

Published: April 2021

Background

Obesity is one of the most important public health problems in the world, which is occurred by various factors. The purpose of this study is to explore the causes of obesity in the Kurdish regions of Iran with a qualitative approach.

Methods

A qualitative content analysis study was conducted in the Kurdish regions of Iran from June 2019 to November 2019. The data were collected by holding focus group discussions and semi-structured interviews with 111 obese and thin men and women, and experts from different fields, who were selected through purposive sampling. Additionally, the data were analyzed by the conventional content analysis approach following the steps proposed by Graneheim and Lundman. The researchers used ATLAS.ti (Version 2019) software for data analysis and management. Lincoln and Guba’s criteria were used to assess the quality of the research.

Results

The results of the data analysis were classified into 5 categories and 16 sub-categories. The main categories included the modern lifestyle, sociocultural norms, indigenous culture of nutrition, lack of institutionalization of exercise, and low health literacy.

Conclusion

Changing people's beliefs and values ​​about obesity and thinness, changing the dietary habits of individuals, expanding and institutionalizing exercise and physical activity, and enhancing health literacy can prevent and control obesity.

Published: April 2021

This study assesses the impact of the introduction of connected and automated vehicles on Virginia freeway corridors. Three vehicle types: legacy vehicles (LV), automated vehicles (AV), and connected automated vehicles (CAV), were considered in mixed traffic scenarios. Previous relevant studies were reviewed and the proper operating parameters for LV, AV, and CAV identified. AV and CAV driving behavior models were developed in the VISSIM environment. According to the basic freeway test network results, AV and CAV increase road capacity by 29% and 91%. In the merging freeway test network, AV and CAV increase road capacity by 48% and 60% compared with LV, respectively. A model with diverse LV, AV, and CAV market penetration and diverse traffic demand was tested on I-95 in Virginia, where the research team tested the speed and throughput. Under the current traffic demand, the average speed was higher when there were more AV and no CAV in the traffic flow. However, the average speed of CAV in a congested segment is higher than LV. In the case of throughput, CAV shows poor performance under current traffic demand. With increased traffic demand, high penetrations of AV and CAV present better performance because of their short headway and homogeneity. Therefore, the study predicts that in the future, as the traffic demand grows, AV and CAV can reduce traffic congestion.

Published: April 2021

Since the 1980s, the falling weight deflectometer (FWD) has been the primary deflection-measuring device in the United States to evaluate the structural conditions of in-service pavements. However, the stop and go nature of the FWD limits its application at the network level. In the early 2000s, the traffic speed deflectometer (TSD) was introduced as an alternate deflection-measuring device for network-level applications. TSD collects deflection measurements while traveling at traffic speed, which provides improved spatial coverage and no traffic disturbance. The verification of TSD measurements is of great interest as many agencies move toward widespread implementation. This study aims at developing a reliable and straightforward procedure for the verification of TSD measurements using limited FWD measured deflection measurements. The verification procedure employs a trained artificial neural network (ANN) model to shift TSD deflections to their corresponding FWD deflections. The ANN model was trained and verified based on FWD and TSD measurements from two deflection-testing programs. The developed model accurately predicted FWD measurements with a coefficient of determination (R2) of 0.994. The suitability of the proposed verification procedure was evaluated using statistical and engineering-based measures and showed acceptable accuracy. Results also validated that the proposed method could be used to verify TSD measurements before its use for conducting deflection measurements at the network level.

Published: April 2021

Large data sets of Washington State Department of Transportation (WSDOT) pavement construction and condition data are linked together and used to investigate an implemented change in in-place density to lower specification limit (LSL) from 91% to 92%. This serves as a test case for using such large in-service data sets to create analysis value for a state DOT. Findings include: (1) WSDOT field density has remained relatively steady at 93% for over 20 years; (2) raising the density LSL to 92% will likely result in more contractor effort to achieve higher densities; (3) no clear trend links density with better pavement condition; (4) raising the density LSL will likely result in fewer problematically low densities; and (5) there is no evidence of differing pavement performance based on asphalt content, gradation, or nominal maximum aggregate size.

Published: April 2021

The paper presents a data-driven framework and related field studies on the use of supervised machine learning and smartphone technology for the spatial condition-assessment mapping of roadway pavement surface anomalies. The study explores the use of data, collected by sensors from a smartphone and a vehicle’s onboard diagnostic device while the vehicle is in movement, for the detection of roadway anomalies. The research proposes a low-cost and automated method to obtain up-to-date information on roadway pavement surface anomalies with the use of smartphone technology, artificial neural networks, robust regression analysis, and supervised machine learning algorithms for multiclass problems. The technology for the suggested system is readily available and accurate and can be utilized in pavement monitoring systems and geographical information system applications. Further, the proposed methodology has been field-tested, exhibiting accuracy levels higher than 90%, and it is currently expanded to include larger datasets and a bigger number of common roadway pavement surface defect types. The proposed system is of practical importance since it provides continuous information on roadway pavement surface conditions, which can be valuable for pavement engineers and public safety.
Incorporating Low-Stress Bicycling Connectivity into Expanded Transit Service Coverage
Authors: Zuo Ting , Wei Heng , Chen Na
Published: April 2021

The speed advantage in bicycling over walking is believed to ease first-and-last mile (F&LM) travel and expand transit service coverage. To quantitatively investigate the potential effect of using bicycle as a F&LM connector, the paper measures and compares the impacts of walking and bicycling F&LM access on transit service coverage. In the estimation of transit service coverage, F&LM travel decay functions representing the attractiveness of public transit that declines with increasing walking/biking time to access transit facilities and the spatial boundaries of transit catchment areas are developed using GPS trajectory data collected from the latest Cincinnati Household Travel Survey in Hamilton County, Ohio. Level of traffic stress is used to evaluate the bicycle suitability of streets and bike network connectivity. Based on the F&LM distance decay functions and low-stress bike network connectivity, the transit service coverage area as well as the transit-served population and employment in Hamilton County, Ohio, are estimated. Results show that more population can reach transit services and therefore employment by bicycling than walking. Meanwhile, disadvantaged groups, that is, low-income and zero-car population, can be better served by transit if using bicycle as the F&LM connector. In addition, low-stress bicycling connectivity is a significant factor determining the bicycle-transit service coverage, and a well-connected low-stress bike network with quality bikeways is crucial to guaranteeing that. These findings can be used as references to assist planners in their decision-making process to achieve better mobility and accessibility.

Introduction:

We aim to present a rare case of a patient who developed a late testicular metastasis of PCa after radical prostatectomy.

Case description:

A 78 years old man presenting for left testicular swelling slowly increasing of size over the last 2 months. He underwent a retropubic radical prostatectomy and extended bilateral lymphadenectomy in 2007 for prostatic adenocarcinoma. At the time of the presentation the last PSA was 0.91 ng/mL. The patient underwent a standard left orchifunicolectomy in April 2019 without intra- or perioperative complications. The pathological analysis showed a testicular metastasis of acinar adenocarcinoma.

Conclusions:

In conclusion, testicular metastasis from PCa are uncommon conditions. PSA evaluation and physical examination of all sites of metastasis and accurate evaluation of all signs/symptoms during the clinical visit remains crucial to the diagnosis of recurrence.
Unequal Opportunity Spreaders: Higher COVID-19 Deaths with Later School Closure in the United States
Authors: Rauscher Emily , Burns Ailish
Published: April 2021

Mixed evidence on the relationship between school closure and COVID-19 prevalence could reflect focus on large-scale levels of geography, limited ability to address endogeneity, and demographic variation. Using county-level Centers for Disease Control and Prevention (CDC) COVID-19 data through June 15, 2020, two matching strategies address potential heterogeneity: nearest geographic neighbor and propensity scores. Within nearest neighboring pairs in different states with different school closure timing, each additional day from a county’s first case until state-ordered school closure is related to 1.5 to 2.4 percent higher cumulative COVID-19 deaths per capita (1,227–1,972 deaths for a county with median population and deaths/capita). Results are consistent using propensity score matching, COVID-19 data from two alternative sources, and additional sensitivity analyses. School closure is more strongly related to COVID-19 deaths in counties with a high concentration of Black or poor residents, suggesting schools play an unequal role in transmission and earlier school closure is related to fewer lives lost in disadvantaged counties.

Published: April 2021

Objectives:

We aimed to evaluate the efficacy of the modified Atkins diet in children with epileptic spasms who had failed hormonal therapy.

Methods:

Children aged 9 months to 3 years having daily epileptic spasms despite a trial of ACTH or oral prednisolone and 1 additional anticonvulsant medication were enrolled. Children were randomly assigned to receive the modified Atkins diet either immediately or after a delay of 4 weeks. The ongoing anticonvulsant medications were continued unchanged. The primary outcome variable was the proportion of children who achieved spasm freedom as per parental reports at 4 weeks. Secondary outcomes included time to spasm cessation, proportion of children with electroclinical remission, the proportion of children with >50% reduction of spasms at 4 weeks, and adverse effects of the diet. ( ClinicalTrials.gov Identifier: NCT03807141).

Results:

A total of 91 children were enrolled in the study; 46 in the diet group and 45 in the control group. At the end of 4 weeks, 11 children in the diet group were spasm free compared with none in the control group ( P ≤ .001). The median time to achieve spasm cessation was 10 days (interquartile range 9-20). Nine of these had resolution of hypsarrhythmia on electroencephalography (EEG). Thirty (65.2%) in the diet group had >50% reduction in spasms, compared with none in the control group ( P < .001). The most common side effect was constipation, noted in 34.8% of the children.

Conclusions:

The modified Atkins diet was found to be effective and well tolerated in children with epileptic spasms refractory to hormonal therapy.
Are value–behavior relations stronger than previously thought? It depends on value importance
Authors: Lee Julie Anne , Bardi Anat , Gerrans Paul , Sneddon Joanne , van Herk Hester , Evers Uwana , Schwartz Shalom
Published: April 2021

Research has found that value–behavior relations are usually weak to moderate. But is this really the case? This paper proposes that the relations of personal values to behavior are stronger at higher levels of value importance and weaker at lower levels. In a large, heterogeneous sample, we tested this proposition by estimating quantile correlations between values and self-reported everyday behavior, at different locations along the distribution of value importance. We found the proposed pattern both for self-reports of everyday behaviors chosen intentionally to be value-expressive and everyday behaviors subject to strong situational constraints (e.g., spending allocation to clothing and footwear). Our findings suggest that value–behavior relations may be stronger than previously recognized, depending on value importance. People who attribute high importance to a value will not only engage in value-expressive behaviors more frequently, but as we move up the value importance distribution, the relations strengthen. In contrast, people who attribute low importance to a value not only engage in value-expressive behaviors less frequently, but as we move down the value importance distribution, the relations weaken. These findings provide important insight into the nature of values.
Precise dynamic modeling of pneumatic muscle actuators with modified Bouw–Wen hysteresis model
Authors: Sheikh Sofla Mohammad , Sadigh Mohammad Jafar , Zareinejad Mohammad
Published: April 2021

Pneumatic muscle actuators (PMAs) are frequently used in a wide variety of biorobotic applications, such as robotic orthoses and wearable exoskeletons, due to their high power/weight ratio and significant compliance. However, the asymmetric hysteresis nonlinearity reduces their fidelity and cause difficulties in the accurate control procedure. In this paper, Bouc–Wen hysteresis model is modified to describe the asymmetric force/length hysteresis of the PMA. The effect of muscle length on hysteretic restoring force is considered in this modified model and experimental results show that the proposed model has a better performance to characterize the asymmetric hysteresis loop of pneumatic muscles. The nonlinear pressure/force model of these actuators also is modeled precisely and its performance is experimentally verified for different muscle lengths.
Design and operational assessment of a low-boom low-drag supersonic business jet
Authors: Sun Yicheng , Smith Howard
Published: April 2021

There has been a worldwide interest to develop a supersonic business jet (SSBJ) for a minimum range of 4000 nm with low sonic boom intensity and high fuel efficiency. An SSBJ design model is developed in the GENUS aircraft conceptual design environment. With the design model, a low-boom low-drag SSBJ concept is designed and optimized. This article studies the design concept for its operational performances. The sustained supersonic cruise flight is studied to find out the fuel-efficient Mach number and altitude combinations. The combined supersonic and subsonic cruise flight scenarios are studied to evaluate the feasibility of boom-free flight routes. The one-stop supersonic cruise flight scenario is studied to compare the fuel consumption and time advantage over subsonic airliners. The off-design sonic boom intensity is studied to explore the operational space assuming there would be a sonic boom intensity limit in the future. Through the studies, it is revealed that there is a corresponding most fuel-efficient operating altitude for a specific cruise Mach number. To operate the aircraft near the cutoff Mach number leads to both increases in the fuel consumption (6.3%–8.1%) and the mission time (11.7%–13.1%). The business-class supersonic transport (231 g/PAX/km) consumes nearly three times fuel as the economic-class supersonic transport (77 g/PAX/km), which is still far more than the economic-class subsonic transport (20 g/PAX/km). Off-design sonic boom intensity studies reveal different trends against the common understanding: the sonic boom intensity does not necessarily decrease as the altitude increases; the sonic boom intensity does not necessarily decrease as the Mach number decreases.
Numerical analysis of the mechanical behaviour of intact and implanted lumbar functional spinal units: Effects of loading and boundary conditions
Authors: Talukdar Rahul Gautam , Mukhopadhyay Kiran Kumar , Dhara Santanu , Gupta Sanjay
Published: April 2021

The objective of this study was to develop an improved finite element (FE) model of a lumbar functional spinal unit (FSU) and to subsequently analyse the deviations in load transfer owing to implantation. The effects of loading and boundary conditions on load transfer in intact and implanted FSUs and its relationship with the potential risk of vertebral fracture were investigated. The FE models of L1-L5 and L3-L4 FSUs, intact and implanted, were developed using patient-specific CT-scan dataset and segmentation of cortical and cancellous bone regions. The effect of submodelling technique, as compared to artificial boundary conditions, on the elastic behaviour of lumbar spine was examined. Applied forces and moments, corresponding to physiologic movements, were used as loading conditions. Results indicated that the loading and boundary conditions considerably affect stress-strain distributions within a FSU. This study, based on an improved FE model of a vertebra, highlights the importance of using the submodelling technique to adequately evaluate the mechanical behaviour of a FSU. In the intact FSU, strains of 200–400 µε were observed in the cancellous bone of vertebral body and pedicles. High equivalent stresses of 10–25 MPa and 1–5 MPa were generated around the pars interarticularis for cortical and cancellous regions, respectively. Implantation caused reductions of 85%–92% in the range of motion for all movements. Insertion of the intervertebral cage resulted in major deviations in load transfer across a FSU for all movements. The cancellous bone around cage experienced pronounced increase in stresses of 10–15 MPa, which indicated potential risk of failure initiation in the vertebra.
Convergent and Discriminant Validity of Retrospective Assessments of the Quality of Childhood Parenting: Prospective Evidence From Infancy to Age 26 Years
Authors: Nivison Marissa D. , Vandell Deborah Lowe , Booth-LaForce Cathryn , Roisman Glenn I.
Published: April 2021

Retrospective self-report assessments of adults’ childhood experiences with their parents are widely employed in psychological science, but such assessments are rarely validated against actual parenting experiences measured during childhood. Here, we leveraged prospectively acquired data characterizing mother–child and father–child relationship quality using observations, parent reports, and child reports covering infancy through adolescence. At age 26 years, approximately 800 participants completed a retrospective measure of maternal and paternal emotional availability during childhood. Retrospective reports of childhood emotional availability demonstrated weak convergence with composites reflecting prospectively acquired observations ( R2s = .01–.05) and parent reports ( R2s = .02–.05) of parenting quality. Retrospective parental availability was more strongly associated with prospective assessments of child-reported parenting quality ( R2s = .24–.25). However, potential sources of bias (i.e., depressive symptoms and family closeness and cohesiveness at age 26 years) accounted for more variance in retrospective reports (39%–40%) than did prospective measures (26%), suggesting caution when using retrospective reports of childhood caregiving quality as a proxy for prospective data.
France – RFA (Séville, 1982) : l’évènement footballistique
Authors: Violette Louis
Published: April 2021

This contribution offers an original reading of the representations surrounding the semi-final of the Football World Cup between France and Germany on 8 July 1982 in Seville. Input and output of the historical process by its status of socio-cultural rupture, this sporting fact postulates to be categorized as a symbolic event. In order to measure its social impacts, the challenge for academic sciences is to objectify its nature. Through a combined analysis of its manifestation, its future and its normalization, this study demonstrates the event-driven dimension of the Seville drama. In fact, captured and relayed by the media in a mythological way, it sees the emergence of a long-term memory movement. The social sciences make the football process of identification intelligible but they have so far failed to explain this still present past.

Authors: An SJ , Lee EJ , Jeong S-H , Hong Y-p , Ahn S , Yang Y-J
Published: April 2021

Introduction:

Di-(2-ethylhexyl) phthalate (DEHP) is a commonly used plasticizer in consumer products and medical devices. It is also suspected to exacerbate the development of fatty liver. However, the mechanisms underlying excessive lipid synthesis and its deposition in the liver are yet to be identified. This study was aimed to evaluate the molecular mechanisms of hepatic lipid accumulation in adult male offspring after perinatal exposure to DEHP.

Method:

Corn oil and DEHP (0.75 mg/kg/day) were administered once per day to dam from gestation day 6 to postnatal day (PND) 21 by oral gavage. After the weaning period, DEHP treated male pups were categorized into early life stage- and lifelong period group. Male rats both control and early life stage group administered corn oil, and lifelong period group administered DEHP from PND 22 to 70. Histological examination and triglyceride (TG) levels in the liver were analyzed. Expressions of transcription factors associated with lipid accumulation in the liver were analyzed.

Results:

Both early life stage- and lifelong period group, hepatic TG levels, and mRNA and protein expression of diacylglycerol acyltransferase 1 (DGAT1) were significantly higher than control (TG: all p < 0.05, mRNA & protein: p < 0.05 and p < 0.001, respectively). The average body weight from PND 35 to 63, and mRNA and protein expression of sterol regulatory element binding protein 1c in lifelong period group were significantly lower than control (all p < 0.05); however, alanine transaminase were significantly higher than control (p < 0.01).

Conclusion:

Perinatal exposure to DEHP may induce the hepatic lipid accumulation through up-regulation of DGAT1 expression.

The United Nation’s 2030 Agenda for Sustainable Development identifies 17 goals as a shared blueprint for peace, prosperity, people and the planet. Australian academic libraries have started documenting and planning how academic libraries contribute to the Sustainable Development Goals (SDGs), including the identification of assessment frameworks and key performance indicators. In 2019, the University of Southern Queensland (USQ) Library stepped through an exercise of understanding how our day-to-day work and annual planning targets mapped to the SDGs. The article is a case study. The authors outline how an academic library’s services, projects and action plans were mapped to the SDGs and how the mapping exercise was communicated to the community. The article will situate this activity among the broader approaches being taken by the Australian library community, including the 2030 stretch targets for Australian libraries. USQ Library staff found that existing services, collections and projects correlated to eight of the 17 SDGs. Activities were mapped to these eight goals and reported to senior executive of the University. The mapping exercise increased the awareness of library staff about the broader cultural and societal implications of their roles. The communication strategy led to conversations that increased university leaders’ awareness of the SDGs and the value and impact of USQ Library in improving access to information as well as the library’s role in transforming the lives of USQ students and community. By undertaking an exercise to map collections, services and projects to the SDGs, USQ Library has been able to demonstrate how their knowledge and information infrastructures which enable student achievement and research excellence. The SDGs can be used by university libraries as a benchmarking tool and as a challenge to set stretch targets aligned with the United Nation’s 2030 agenda.

Authors: Sisselman-Borgia Amanda , Budescu Mia , Torino Gina , Ramos Massiel
Published: April 2021

Microaggressions, or subtle forms of discrimination, are associated with poor mental and physical health as well as chronic stress and disease. The current study sought to add to the microaggressions literature by exploring the effects of socioeconomic status (SES)-based microaggressions on the mental health of urban low-income adolescents. Data were collected from 291 adolescents in New York City regarding experiences with SES-based microaggressions and their association with mental health symptoms. Multiple regression models indicated that higher levels of agreement with experiences of SES microaggressions were positively associated with higher levels of anxiety, depression, somatic symptoms, obsessive-compulsivity, and interpersonal sensitivity among Black youth. The association was not significant for White or LatinX youth. Implications for youth, families, and communities are discussed.
An Exploration of Co-Workers’ Group Identification as Moderator of the Leadership-Health Link
Authors: Fladerer Martin P. , Kugler Sonja , Kunze Louisa G.
Published: April 2021

This study explores the leadership-health link from a social identity perspective. It focuses on leadership behaviors that seek to form a strong shared social identity (i.e., identity leadership) and the contextual influence of co-workers’ group identification. In a sample of 319 members in 77 workgroups, data supports the indirect link of identity leadership and reduced symptoms of burnout via perceived social support. However, contrary to our expectation, high levels of co-workers’ group identification weakened the relationship of identity leadership and perceived social support. The implications of this finding for the understanding of leadership as a group process are discussed.
Pulp Friction in the La Plata Basin: The Importance of Natural Resource Governance for South American Regionalism
Authors: Siegel Karen M.
Published: April 2021

Over the last two decades, natural resource governance has become an increasingly important element of South American regionalism as commodities became a central driver for regional development strategies. Yet, due to socio-environmental impacts and dissatisfaction with decision-making processes, it is also frequently contested. This article focuses on one particularly prominent contestation with transboundary and regional repercussions, the case of the pulp mill conflict which escalated between Argentina and Uruguay in the 2000s. Using the concepts of regionness and politics of scale, it examines in which ways the pulp mill conflict affected regional cohesion and seeks to understand why it evolved in this way. This shows that the way national governments address socio-environmental conflicts is an important additional obstacle to regional cohesion which has received little attention in studies of South American regionalism so far.

Authors: Kiyat Pelin , Palamar Melis , Gerceker Turk Bengu
Published: April 2021

Purpose:

To analyze the relation between Meibomian gland dysfunction, dry eye, and sarcoidosis.

Materials and Methods:

Twenty eyes of 10 sarcoidosis patients (Group 1) and 20 left eyes of 20 age-sex matched healthy volunteers (Group 2) were included. Presence of dry eye was evaluated with Schirmer 1 test, tear film break-up time (T-BUT), Oxford scale scoring, Ocular Surface Disease Index (OSDI) score assessments. A slit-lamp biomicroscope infrared filter (Topcon, SL-D701, IJssel, The Netherlands) was used to evaluate Meibomian glands. The drop-out ratio according to meibography was scored for each eyelid from grade 0 (no loss) through grade 3 (lost area >2/3 of the total Meibomian gland area).

Results:

Among dry eye tests mean Schirmer 1 and T-BUT values were lower and OSDI score was higher in Group 1 compared to Group 2 and the differences were statistically significant ( p = 0.017, p = 0.039, p = 0.003, respectively). In addition, the upper, lower and total meiboscores were statistically significantly higher in Group 1 ( p = 0.047, p = 0.003, p = 0.005, respectively).

Conclusion:

A significantly higher presence of dry eye and Meibomian gland drop out ratios was detected in sarcoidosis patients. It is important to monitor sarcoidosis patients for dry eye and Meibomian gland dysfunction and when detected, to treat adequately to prevent ocular surface damage.

Authors: Perkins Thomas J , Kop Alan M , Whitewood Colin , Pabbruwe Moreica B
Published: April 2021

Background:

Although the Pinnacle Acetabular Hip System (DePuy Synthes) has demonstrated excellent survivorship results since it was first introduced in 2003, there have been a growing number of cases indicating that Pinnacle liners may be subject to a higher-than-expected rate of early dissociation failure. Between 2006 and 2020, our Centre received 212 retrieved Pinnacle liners from Western Australian hospitals. Of these, 26 were removed due to liner dissociation.

Methods:

To better understand the frequency and cause of this complication we assessed all retrieved Pinnacle acetabular components for type, damage modes and patient demographics. The leverage force required to dissociate Pinnacle liners was also measured and compared with another commonly used acetabular system, the Trident (Stryker Orthopaedics).

Results:

The estimated minimum incidence of liner dissociation from our data was 0.35%. Characterisation of dissociated Pinnacle cases (n = 26) revealed 73% were female with an average age of 59 compared to all retrieved Pinnacle cases (n = 212) where 58% were female with an average age of 66. Retrieval analysis indicated plastic deformation of the liner into an ovoid shape, signs of impingement on the rim postero-superiorly and shearing of the liner’s anti-rotation tabs was common. Mechanical testing indicated that the dissociation strength of Pinnacle cups decreases at approximately 6.6 N/year in situ (p = 0.01).

Conclusion:

The survival rate of Pinnacle acetabular cups is exceptional with only 5% revised at 10 years. However, surgeons should be aware of the clinical symptoms and high-risk demographics when assessing patients with polyethylene Pinnacle liners.

The emerging pathogen SARS-CoV2 causing coronavirus disease 2019 (COVID-19) is a global public health challenge. To the present day, COVID-19 had affected more than 40 million people worldwide. The exploration and the development of new bioactive compounds with cost-effective and specific anti-COVID 19 therapeutic power is the prime focus of the current medical research. Thus, the exploitation of the molecular docking technique has become essential in the discovery and development of new drugs, to better understand drug-target interactions in their original environment. This work consists of studying the binding affinity and the type of interactions, through molecular docking, between 54 compounds from Moroccan medicinal plants, dextran sulfate and heparin (compounds not derived from medicinal plants), and 3CLpro-SARS-CoV-2, ACE2, and the post fusion core of 2019-nCoV S2 subunit. The PDB files of the target proteins and prepared herbal compounds (ligands) were subjected for docking to AutoDock Vina using UCSF Chimera, which provides a list of potential complexes based on the criteria of form complementarity of the natural compound with their binding affinities. The results of molecular docking revealed that Taxol, Rutin, Genkwanine, and Luteolin-glucoside have a high affinity with ACE2 and 3CLpro. Therefore, these natural compounds can have 2 effects at once, inhibiting 3CLpro and preventing recognition between the virus and ACE2. These compounds may have a potential therapeutic effect against SARS-CoV2, and therefore natural anti-COVID-19 compounds.

The nursing schedule generation is an important activity that takes a considerable amount of time for managers to prepare and amend. It involves the optimal allocation of nurses to shifts, factoring various constraints like shift timings, holidays, leaves, and emergencies. This paper provides the design and development details for an automated nurse scheduling system called “ROTA,” implemented for a 2032 bed multi-specialty tertiary teaching hospital, having 1800 staff nurses and 98 wards. The system generates daily, weekly, monthly schedules, nurse face sheets, duty allocation charts, swapping schedules, and training details for nurses. The system improved managerial control and saved a considerable amount of time for nurses to prepare the schedule. A survey conducted to gauge the system’s satisfaction level showed that 91% of nurses were satisfied with ROTA. Overall, the system saved 78% of nurse scheduling time, resulting in a 3% cost reduction for the hospital.
Narratives of normality: Finnish prisoners envisioning their future
Authors: Villman Emma
Published: April 2021

The ambition of living ‘a normal life’ appears to be common among prisoners prior to release. Besides portraying for the life desired upon release, the notion of a normal life can say something about what the persons aspiring to it thinks of their present life, what they want their life to be like in future, and what they consider attainable. This article explores the subjective and social considerations of prisoners’ desires for normality. Qualitative interviews with prisoners at low-security open prisons in Finland ( N = 45) revealed three narratives of normality: (1) nostalgic normality, balancing the disruption caused by imprisonment; (2) imagined normality, envisioning a future life script; (3) challenging views of normality, which is still desired, but whose legal and conventional norms are contested. While prison authorities and prisoners generally idealize normality in terms of conduct, prisoners’ stories reveal that they utilize the notion for a number of reasons. The personal narratives of normality can function as genuine and strategic expressions of conformity or resistance. In their narratives, the prisoners disclose the obstacles to normality that they anticipate, showing the uncertainty behind their simple wish to “just live a normal life.”
Cavitation between cylinder-liner and piston-ring in a new designed optical IC engine

Published: April 2021

A new engine block with optical access has been designed and manufactured capable of running up to 3000 r/min with the same specification as the unmodified engine. The optical window allowed access to the full length of the liner over a width of 25 mm to investigate the lubricant flow and cavitation at contact point between the rings and cylinder-liner. In addition, it allowed good access into the combustion chamber to allow charged flow, spray and combustion visualisation and measurements using different optical methods. New custom engine management system with build in LabView allowed for the precise full control of the engine. The design of the new optical engine was a great success in producing high quality images of lubricant flow, cavitation formation and development at contact point at different engine speeds ranging from 208 to 3000 r/min and lubricant temperatures (30°C–70°C) using a high-speed camera. The results under motorised operation confirmed that there was no cavitation at contact points during the intake/exhaust strokes due to low in-cylinder presure, while during compression/expansion strokes, with high in-cylinder pressure, considerable cavities were observed, in particular, during the compression stroke. Lubricant temperatures had the effect of promoting cavities both in their intensity and covered ring area up to 50°C as expected. Beyond that, although the cavitation intensity increases further with temperature, its area reduces due to possible collapse of the cavitating bubbles at higher temperature. The change of engine speed from 208 to 800 r/min increased cavitating area considerably by 52% of the ring area and was further increased by 19% at 1000 r/min. After that, the results showed very small increase in cavitation area (1.3% at 2000 r/min) with similar intensity and distribution across the ring.

Authors: Mishra Anubhav A , Verma Megha
Published: April 2021

This study explores the lived phenomenon of customer experience (CX) across the customer decision journey of two divergent segments of customers in a naturalistic environment. Specifically, the study focusses on understanding the similarities and differences with respect to—(a) dimensions of CX, (b) consequences of CX, (c) moderators of CX, and (d) situating CX in customer decision journey. The findings are in congruence with the various theories from cognitive psychology, environmental psychology, and economic geography. The findings contribute to existing research that is primarily focussed on conceptualizing and measuring CX by providing an in-depth analysis of its formation for these two customer segments. Managers can utilize the findings to identify these touchpoints that lead to relevant customer responses. In all, the propositions drawn from the study findings are assimilated in the theoretical framework that adds to the nascent research on CX and customer decision journey.
