“The Pause”: A Delphi Methodology Examining an End-of-Life Practice
Authors: Cunningham Tim , Ducar Dallas M. , Keim-Malpass Jessica
Published: January 2019

“The Pause” was first practiced by a nurse at a Level 1 trauma center to honor the death of a deceased patient. This practice has spread internationally and is used in emergency departments, intensive care, transplant, and oncology units, in addition to pre-hospital settings. There is a paucity of research published on the effects of The Pause for health care workers. We used a three-staged Delphi methodology to understand the barriers, benefits, and language used in The Pause. Analyses of email communication and interview transcripts suggest that The Pause poses minimal risk and has considerable benefits. Benefits include increased perceived team cohesion, a moment for reflection, and a method by which to honor a deceased patient. The Pause allows nurses to feel more present to meet the needs of the next patient they care for during a shift. Further research is merited.
Perspectives of bereaved relatives of patients with haematological malignancies concerning preferred place of care and death: A qualitative study
Authors: McCaughan Dorothy , Roman Eve , Smith Alexandra G , Garry Anne C , Johnson Miriam J , Patmore Russell D , Howard Martin R , Howell Debra A
Published: January 2019

Background:

People with haematological malignancies have different end-of-life care patterns from those with other cancers and are more likely to die in hospital. Little is known about patient and relative preferences at this time and whether these are achieved.

Aim:

To explore the experiences and reflections of bereaved relatives of patients with leukaemia, lymphoma or myeloma, and examine (1) preferred place of care and death; (2) perceptions of factors influencing attainment of preferences; and (3) changes that could promote achievement of preferences.

Design:

Qualitative interview study incorporating ‘Framework’ analysis.

Setting/participants:

A total of 10 in-depth interviews with bereaved relatives.

Results:

Although most people expressed a preference for home death, not all attained this. The influencing factors include disease characteristics (potential for sudden deterioration and death), the occurrence and timing of discussions (treatment cessation, prognosis, place of care/death), family networks (willingness/ability of relatives to provide care, knowledge about services, confidence to advocate) and resource availability (clinical care, hospice beds/policies). Preferences were described as changing over time and some family members retrospectively came to consider hospital as the ‘right’ place for the patient to have died. Others shared strong preferences with patients for home death and acted to ensure this was achieved. No patients died in a hospice, and relatives identified barriers to death in this setting.

Conclusion:

Preferences were not always achieved due to a series of complex, interrelated factors, some amenable to change and others less so. Death in hospital may be preferred and appropriate, or considered the best option in hindsight.
Minocycline and the risk of acute psychiatric events in adolescence: A self-controlled case series
Authors: Brauer Ruth , Herrero-Zazo Maria , Barlow David J , Gaughran Fiona , Taylor David , Howard Louise M
Published: January 2019

Background

Minocycline has neurological anti-inflammatory properties and has been hypothesised to have antipsychotic effects.

Aim

The aim of this study was to investigate, using routinely collected United Kingdom primary health care data, whether adolescent men and women are more or less likely to receive an urgent psychiatric referral during treatment for acne with minocycline compared with periods of non-treatment.

Method

A self-controlled case series using United Kingdom Clinical Practice Research Datalink to calculate the incidence rate ratio of urgent psychiatric referrals for individuals, comparing periods during which minocycline was prescribed with unexposed periods, adjusted for age.

Results

We found 167 individuals who were at the time exposed to minocycline for a mean of 99 days and who received an urgent psychiatric referral. There was no difference in psychiatric referral risk during periods of exposure compared with periods of non-exposure: incidence rate ratio first 6 weeks of exposure 1.96, 95% confidence interval 0.82–4.71, p=0.132; incidence rate ratio remaining exposure period=1.97, 95% confidence interval 0.86–4.47, p=0.107.

Conclusions

We found no evidence in support of a protective effect of minocycline against severe psychiatric symptoms in adolescence.
Perinatal exposure to fluoxetine increases anxiety- and depressive-like behaviours and alters glutamatergic markers in the prefrontal cortex and hippocampus of male adolescent rats: A comparison between Sprague-Dawley rats and the Wistar-Kyoto rat model of depression
Authors: Millard Samuel J , Lum Jeremy S , Fernandez Francesca , Weston-Green Katrina , Newell Kelly A
Published: January 2019

Background:

With approximately 10% of pregnant women prescribed antidepressant drugs for the treatment of depressive disorders, there is growing concern regarding the potential long-term effects of this exposure on offspring. Research is needed in clinically relevant models to determine the effects on offspring behaviour and associated neurobiological systems.

Aim:

The aim of this study was to determine the effects of maternal fluoxetine treatment on anxiety-like and depressive-like behaviours in adolescent offspring as well as associated glutamatergic markers, using a clinically relevant rodent model of depression.

Methods:

Wistar-Kyoto (model of innate depression) and Sprague-Dawley rats were treated with fluoxetine (10 mg/kg) from gestational day 0 to postnatal day 14. Male offspring underwent behavioural testing (open field, elevated plus maze, forced swim test) at adolescence followed by quantitative immuno-detection of glutamatergic markers in the prefrontal cortex and ventral hippocampus.

Results:

Perinatal fluoxetine exposure exacerbated the anxiety-like and depressive-like phenotype in Wistar-Kyoto offspring and induced an anxiety-like and depressive-like phenotype in Sprague-Dawley offspring. Wistar-Kyoto offspring showed reductions in NMDA receptor NR1, NR2A and NR2B subunits, as well as post-synaptic density 95 (PSD-95) and metabotropic glutamate receptor subtype 1 (mGluR1) in the prefrontal cortex; perinatal fluoxetine exposure further reduced NR1, NR2A, PSD-95 and mGluR1 expression in Wistar-Kyoto as well as Sprague-Dawley offspring. In the ventral hippocampus perinatal fluoxetine exposure reduced PSD-95 and increased metabotropic glutamate receptor subtype 5 (mGluR5) and Homer1b/c in both Sprague-Dawley and Wistar-Kyoto strains.

Conclusion:

These findings suggest that maternal fluoxetine treatment exacerbates effects of underlying maternal depression on offspring behaviour, which may be mediated through alterations in the glutamatergic system. Further research investigating how to minimise these effects, whilst ensuring optimal treatment for mothers, is essential to move the field forward.
Effect of Emulsion Type on Bond Behavior of Asphalt Concrete Layers in Cold Regions
Authors: Stasiuk Laura , Soliman Haithem , Anthony Ania
Published: January 2019

Tack coat materials, which are typically emulsified bituminous products, are used to provide a sufficient bond between asphalt concrete (AC) layers/lifts. Owing to construction limitations and severe temperature variations in cold regions, agencies are investigating the use of fast curing and non-tracking emulsions as tack coat materials. The objective of this study is to evaluate the performance of various tack coat products in cold climates. Several tack coat products were installed during a field study in Saskatchewan, Canada. The tack coat products included slow setting, medium setting, and three proprietary fast curing/non-tracking emulsions. Core samples were collected three weeks after construction to evaluate the initial interlayer shear strength (ISS) for typical construction conditions in cold regions. Although the ISS values for all of the products, except one SS-1 section, varied in a narrow range, this does not indicate that all products will have a similar long-term performance. The modes of failure for the bond strength samples were classified into two types according to the shape and location of the failure surface: type A and type B. Failure type B indicates that the tack coat material can successfully provide sufficient bond strength to make the two AC lifts behave as one thick homogenous layer. The results showed that the failure mode should be included as an evaluation criterion in addition to ISS. The results showed that the energy required to reach peak shear stress is a comprehensive parameter that should also be considered when evaluating tack coat materials.
Implications of Field Loading Patterns on Different Tie Support Conditions using Discrete Element Modeling: Dynamic Responses
Authors: Feng Bin , Hou Wenting , Tutumluer Erol
Published: January 2019

With increasing demands for rail passenger and freight operations, sharing a line or track is an economical solution if operational efficiency and track reliability challenges can be accommodated properly. This paper presents findings of ballast layer dynamic responses related to four different freight and passenger car loading patterns studied for four different tie support conditions using the Discrete Element Method (DEM). With the DEM model setup being identical for each support condition, ballast particle contact force networks were visualized first under one dynamic load cycle. Certain load transfer chains were observed associated with all four support conditions. Next, crosstie dynamic velocities were analyzed for all sixteen combinations of the different loading patterns and support conditions. The freight car loads traveling at 50 mph could induce higher crosstie vibration velocities than the lighter passenger car loads traveling at 110 mph and 150 mph in three support conditions: lack of center support, high center binding, and lack of rail seat support. Dynamic movements of ballast particles were visualized in velocity vector plots based on their initial and final centroid coordinates. Results reveal that for the same axle load, higher speeds will cause larger ballast particle movements. However, with higher load magnitudes, larger particle movements can be observed even at lower speeds. Generally, high center binding results in the smallest particle movement while lack of center support presents the largest particle movement. Dynamic load responses of the ballast layer simulations provide insights into evaluating and optimizing tracks to be shared by passenger and freight trains.
Nonbeneficial Intensive Care: Misalignments Between Provider Assessments of Benefit and Use of Invasive Treatments
Authors: Hwe Christopher , Parrish Jennifer , Berry Bryan , Stens Oleg , Chang Dong W.
Published: January 2019

Background:

The purpose of this study was to examine how frequently invasive intensive care unit (ICU) treatments are delivered to critically ill patients despite clinicians’ impressions that ICU care may be nonbeneficial.

Methods:

Patients admitted to the medical ICU of an academic public hospital were prospectively categorized according to guidelines from the Society of Critical Care Medicine which classifies patients based on severity of illness and likelihood of recovery (categories 1-4). Clinical data and use of ICU treatments in patients with high (category 1) and low (category 3) likelihoods of benefit were collected by chart review. Multivariable regression analyses examined associations between use of invasive treatments and patient categories, and clinical factors associated with receiving invasive ICU treatments despite low likelihood of benefit.

Results:

There were 533 patients (369 in category 1 and 164 in category 3) in the study. A total of 19.8%, 29.9%, and 28.9% of patient-days on mechanical ventilation, vasopressors, and renal replacement therapy, respectively, were delivered to patients who were considered unlikely to benefit from ICU treatments (category 3) and ultimately did not survive hospitalization. These patients also received 35.2% of cardiopulmonary resuscitation attempts and 22.6% of central venous catheter placements. Clinicians’ impressions of likelihood of benefit (category 1 vs 3) were not associated with odds of receiving invasive ICU treatments. Clinical characteristics associated with greater odds of receiving potentially nonbeneficial treatments included older age, presence of dementia or malignancy, and higher Acute Physiologic Assessment and Chronic Health Evaluation score.

Conclusions:

Invasive ICU treatments are frequently delivered to patients who are not expected to benefit from ICU care and die during hospitalization. These findings highlight the need to improve utilization of ICU services among patients with advanced medical illnesses.
Fall Worry Restricts Social Engagement in Older Adults
Authors: Choi Namkee G. , Bruce Martha L. , DiNitto Diana M. , Marti C. Nathan , Kunik Mark E.
Published: January 2019

Objective: To examine cross-sectional and longitudinal associations between (a) activity-limiting fall worry (ALW) and (b) self-reported health-related restrictions and social engagement among older adults. Method: The National Health and Aging Trends Study Waves 5 (T1) and 6 (T2) provided data ( n = 6,279). Binary and multinomial logistic regression models were used to examine association of T2 social engagement restrictions with T2 fall worry and association of T1–T2 changes in social engagement restrictions with T1–T2 changes in fall worry. Results: ALW was significantly associated with both informal and formal social engagement restriction at T2. Onset of ALW and continued ALW between T1 and T2 were also significantly associated with newly reported restrictions in both informal and formal social engagement at T2 even controlling for falls incidents and changes in health status and other covariates. Discussion: The findings underscore the importance of reducing fall worry and preventing social disengagement in late life.

Published: January 2019

Objective: The objective of this study was to estimate healthy life expectancies in eight low- and middle-income countries (LMICs), using two indicators: disability-free life expectancy (DFLE) and dependence-free life expectancy (DepFLE). Method: Using the Sullivan method, healthy life expectancy was calculated based on the prevalence of dependence and disability from the 10/66 cohort study, which included 16,990 people aged 65 or above in China, Cuba, Dominican Republic, India, Mexico, Peru, Puerto Rico, and Venezuela, and country-specific life tables from the World Population Prospects 2017. Results: DFLE and DepFLE declined with older age across all sites and were higher in women than men. Mexico reported the highest DFLE at age 65 for men (15.4, SE = 0.5) and women (16.5, SE = 0.4), whereas India had the lowest with (11.5, SE = 0.3) in men and women (11.7, SE = 0.4). Discussion: Healthy life expectancy based on disability and dependency can be a critical indicator for aging research and policy planning in LMICs.
Association of Financial Burden With Self-Rated and Mental Health in Older Adults With Cancer
Authors: Jones Salene M. W. , Nguyen Trung , Chennupati Shasank
Published: January 2019

Objective: Financial problems in cancer survivors are associated with distress and reduced quality of life. Most studies have been cross-sectional, and a longitudinal study is needed to guide clinical interventions. Method: We used data from two surveys of the National Health and Aging Trends Study (NHATS). Participants ( n = 307) reported whether they experienced six indicators of financial burden. The Patient Health Questionnaire 4 assessed depressive symptoms and general anxiety. Cross-lagged panel analyses assessed whether financial burden predicted distress and health or vice versa. Results: In the total sample, financial burden at the first survey predicted depressive symptoms ( p < .01), general anxiety ( p < .01), and self-rated health ( p < .01) at the second survey. Depressive symptoms, general anxiety, and self-rated health at the first survey did not predict later financial burden ( ps > .05). Discussion: Results suggest financial problems predict later distress and poor health. This study highlights the need to address financial burden in cancer survivors.
A cross-cultural examination of fat women’s experiences: Stigma and gender in North American and Finnish culture
Authors: Gailey Jeannine A. , Harjunen Hannele
Published: January 2019

In this manuscript, the voices of women of size in North America and Finland indicate that there is a shared experience of being fat. Based on cross-cultural analysis of our respective empirical findings, we argue that there is a shared Western fat lived experience that perpetuates a stigmatized gendered landscape of living with a fat body. The emergent themes tended to revolve around two similar contradictions—the phenomenon of hyper(in)visibility and a belief their fatness is a temporary or liminal state—both of which lead to an internalization of fat hatred. We argue that these findings stem from the tremendous stigma and mistreatment that both samples of women face in their daily lives. The present study contributes to the literature by addressing two research lacunas: 1) the lack of cross-cultural research in fat studies; and 2) the limited mainstream feminist research from the perspective of fat women.
Fatal hepatic sarcocystosis in a free-ranging grizzly bear cub associated with Sarcocystis canis–like infection
Authors: Britton Ann P. , Bidulka Julie , Scouras Andrea , Schwantje Helen , Joseph Tomy
Published: January 2019

We describe herein fatal hepatic sarcocystosis in a free-ranging grizzly bear ( Ursus arctos horribilis) cub with apicomplexan infection of the liver and brain, both demonstrating 100% homology for Sarcocystis canis and S. arctosi. Fatal hepatic sarcocystosis in dogs has been etiologically associated with intrahepatic schizonts of S. canis. In black and polar bears, a S. canis–like organism produces schizonts in the liver and massive hepatic necrosis. Although intramuscular sarcocysts, taxa S. arctosi and S. ursusi, have been described in healthy brown and black bears, respectively, they have not been detected in bears with hepatic sarcocystosis, to our knowledge, and it is currently unknown whether bears represent an aberrant or intermediate host.

Published: January 2019

Patients with chronic illness are associated with high health-care utilization and this is exacerbated in the end of life, when health-care utilization and costs are highest. Complex Care Management (CCM) is a model of care developed to reduce health-care utilization, while improving patient outcomes. We aimed to examine the relationship between health-care utilization patterns and patient characteristics over time in a sample of older adults enrolled in CCM over the last 2 years of life. Generalized estimating equation models were used. The sample (n = 126) was 52% female with an average age of 85 years. Health-care utilization rose sharply in the last 3 months of life with at least one hospitalization for 67% of participants and an emergency department visit for 23% of participants. In the last 6 months of life, there was an average of 2.17 care transitions per participant. The odds of hospitalization increased by 27% with each time interval ( P < .001). Participants demonstrated 11% greater odds of having a hospitalization for each additional comorbidity ( P = .05). A primary diagnosis of heart failure or coronary artery disease was associated with 21% greater odds of hospitalization over time compared to other primary diagnoses ( P = .017). Females had 70% greater odds of an emergency department visit compared to males ( P = .046). For each additional year of life, the odds of an emergency department visit increased by about 7% ( P < .001). Findings suggest the need for further interventions targeting chronically ill older adults nearing end of life within CCM models.
Riding the Special Education Technology Wave: Policy, Obstacles, Recommendations, Actionable Ideas, and Resources
Authors: Thomas Cathy Newman , Peeples Katherine N. , Kennedy Michael J. , Decker Mary
Published: January 2019

This article provides an overview of the literature on special education law and policy and teacher preparation for special education technology use and identifies current issues, focusing on four key obstacles regarding the status of special education technology access and implementation: (a) the mismatch between legal requirements, policy recommendations, and the supports students with disabilities actually receive in schools; (b) the limited professional knowledge about special education technology and few meaningful options for making improvements to this professional body of knowledge; (c) the rapid pace of innovation in terms of availability of new apps, products, and hardware; and (d) the inherent conflicts between the commercial nature of special education technology and best special education technology practice. Recommendations, resources, and actionable ideas toward transformative change are shared with hopes for equitable and meaningful special education technology access and implementation for students with disabilities.
Effects of Vapocoolant Spray Prior to SC LMWH Injection: An Experimental Study
Authors: Unal Nursemin , Tosun Betul , Aslan Ozlem , Tunay Servet
Published: January 2019

The aim of this study was to evaluate the effects of vapocoolant spray administration prior to subcutaneous (SC) low molecular weight heparin injection on local ecchymosis, hematoma, and pain. This randomized controlled study was carried out on 64 patients ( n = 128 injections) in an orthopedics and traumatology clinic. After randomization, vapocoolant spray and then heparin injection was applied on one arm. The second necessary dose of heparin was applied to his or her other arm as a placebo by a water spray. Then, the pain of the patients was assessed. After 2 days, ecchymosis and hematoma were evaluated. Significant lower pain scores were determined in applications in which the vapocoolant spray was used. There was no statically significant difference between the mean diameter values of ecchymosis in both arm groups. There was no hematoma on the injection site after injections. However, this method did not create any significant reductive effect on ecchymosis. Nurses are advised to take advantage of vapocoolant spray effects prior to SC heparin injection.
Dentoalveolar Arch Dimensions in UCLP Boys After Neonatal Cheiloplasty or After Lip Surgery at the Age of 3 or 6 Months
Authors: Kotova Magdalena , Urbanova Wanda , Sukop Andrej , Peterkova Renata , Peterka Miroslav , Petrova Tereza
Published: January 2019

Objective:

To compare the influence of 3 different time protocols of cleft lip and palate operations on the growth of the dentoalveolar arch in patients with unilateral cleft lip and palate (UCLP).

Materials and Methods:

We evaluated 64 plaster casts of 8-year-old boys with UCLP operated on according to 3 different time protocols: lip repair at the age of 6 months and palate repair at 4 years, lip repair at 3 months and palate repair at 9 months, and neonatal lip repair and palate repair at 9 months. The control group contained 13 plaster casts of 8-year-old boys. The dentoalveolar arch width was measured between deciduous canines and between the second deciduous molars; the length was measured between incisive papilla and the line connecting both tuber maxillae.

Results:

All measured distances were statistically significantly smaller in boys with UCLP than in the control group. Intercanine width was not statistically significantly different between the patients operated on according to the different time protocols. In comparison to the lip repair at 6 months and palate repair at 4 years, the intermolar width was statistically significantly smaller in the group with neonatal lip repair; the alveolar arch length was statistically significantly shorter in both groups with lip repair performed neonatally or at 3 months.

Conclusions:

The length of the dentoalveolar arch is shorter after surgical repair of cleft lip neonatally or at the age of 3 months. Cleft palate repair at 9 months can contribute to a reduction in the width of the dentoalveolar arch.
Outcomes of Salvage Arthrodesis and Arthroplasty for Failed Osteochondral Allograft Transplantation of the Ankle
Authors: Gaul Florian , Barr Cameron R. , McCauley Julie C. , Copp Steven N. , Bugbee William D.
Published: January 2019

Background:

Osteochondral allograft (OCA) transplantation is a useful treatment for posttraumatic ankle arthritis in young patients, but failure rates are high and reoperations are not uncommon. The aim of this study was to evaluate the outcomes of failed ankle OCA transplantation converted to ankle arthrodesis (AA) or total ankle arthroplasty (TAA).

Methods:

We evaluated 24 patients who underwent salvage procedures (13 AA and 11 TAA) after primary failed ankle OCA transplantation. Reoperations were assessed. Failure of the salvage procedure was defined as an additional surgery that required a revision AA/TAA or amputation. Evaluation among nonfailing ankles included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM), pain, and satisfaction.

Results:

In the salvage AA cohort, 3 patients were classified as failures (2 revision AA and 1 amputation). The 10 nonfailing patients had a mean follow-up of 7.4 years. Eighty-eight percent were satisfied with the procedure, but 63% reported continued problems with their ankle (eg, pain, swelling, stiffness). Mean pain level was 1.9 and AAOS-FAM core score was 83±13. In the salvage TAA cohort, 2 patients were classified as failures (both revision TAA). The 9 nonfailing patients had a mean follow-up of 3.8 years. Fifty percent were satisfied with the procedure, but 40% reported continued problems with their ankle. The mean pain level was 1.3, and the median AAOS-FAM core score was 82±26.

Conclusion:

Revision and reoperation rates for salvage procedures following failed OCA transplantation of the ankle are higher compared to published data for primary AA and TAA procedures. However, we believe OCA transplantation can serve as an interim procedure for younger patients with advanced ankle joint disease who may not be ideal candidates for primary AA or TAA at the time of initial presentation.

Systematic study of homogenization and the utility of circular simplified representative volume element
Authors: Firooz Soheil , Saeb Saba , Chatzigeorgiou George , Meraghni Fodil , Steinmann Paul , Javili Ali
Published: January 2019

Although both computational and analytical homogenization are well-established today, a thorough and systematic study to compare them is missing in the literature. This manuscript aims to provide an exhaustive comparison of numerical computations and analytical estimates, such as Voigt, Reuss, Hashin–Shtrikman, and composite cylinder assemblage. The numerical computations are associated with canonical boundary conditions imposed on either tetragonal, hexagonal, or circular representative volume elements using the finite-element method. The circular representative volume element is employed to capture an effective isotropic material response suitable for comparison with associated analytical estimates. The analytical results from composite cylinder assemblage are in excellent agreement with the numerical results obtained from a circular representative volume element. We observe that the circular representative volume element renders identical responses for both linear displacement and periodic boundary conditions. In addition, the behaviors of periodic and random microstructures with different inclusion distributions are examined under various boundary conditions. Strikingly, for some specific microstructures, the effective shear modulus does not lie within the Hashin–Shtrikman bounds. Finally, numerical simulations are carried out at finite deformations to compare different representative volume element types in the nonlinear regime. Unlike other canonical boundary conditions, the uniform traction boundary conditions result in nearly identical effective responses for all types of representative volume element, indicating that they are less sensitive with respect to the underlying microstructure. The numerical examples furnish adequate information to serve as benchmarks.
Surgical approach does not affect deep infection rate after primary total hip arthroplasty
Authors: Triantafyllopoulos Georgios K , Memtsoudis Stavros G , Wang Haijun , Ma Yan , Alexiades Michael M , Poultsides Lazaros A
Published: January 2019

Background:

There is a concern for higher rates of wound complications and a potentially increased periprosthetic joint infection (PJI) risk after total hip arthroplasty (THA) with the direct anterior approach (DAA) compared to the posterolateral approach (PLA). Our purpose was to compare PJI risk after THA with the DAA or the PLA and to identify risk factors for PJI after primary THA.

Methods:

Clinical characteristics of patients treated in our institution with primary DAA or PLA THA between 1/2010 and 12/2015 were retrospectively reviewed. The respective deep PJI rates were calculated. A logistic regression model was constructed to determine a potential difference in the PJI risk between the 2 groups, and risk factors for hip PJI in all patients.

Results:

During the period studied, there were 1,182 DAA THAs and 18,853 PLA THAs. The PJI rate was 0.25% for the DAA group and 0.31% for the PLA group ( p = 1.0). The DAA was not associated with a significantly increased risk for PJI compared to the PLA. Compared to younger patients, older patients had lower PJI risk; patient discharge to home was also associated with lower PJI risk compared to other discharge disposition; longer length of stay was associated with higher PJI risk compared to shorter length of stay.

Conclusion:

The DAA is equally safe compared the PLA with respect to PJI risk. Younger age, discharge to facilities other than home and increased length of stay increase the risk for deep PJI after primary THA.
Novel insights from actigraphy: Anxiety is associated with sleep quantity but not quality during childhood
Authors: Cohodes Emily M , Abusch Aviva , Odriozola Paola , Gee Dylan G
Published: January 2019

Anxiety and sleep function change dynamically across development, and sleep dysfunction has emerged as a correlate and predictor of anxiety in pediatric clinical samples. Despite this, previous research has not investigated how associations between qualitative and quantitative measures of sleep function change with anxiety across development, specifically from childhood to adolescence. The present study used actigraphy collection to examine whether associations between quantitative and qualitative sleep function and anxiety differed as a function of developmental stage in a community pediatric sample (8–17 years old; N = 92). Age moderated the association between anxiety and sleep quantity, but not sleep quality. Contrary to hypotheses, higher anxiety was related to increased sleep for children, but not adolescents. Results suggest age-related changes in the association between sleep function and anxiety across development, with implications for targeting sleep-related interventions for youth with anxiety.
Turning the Pushkin Museum into a ‘Russian Tate’: Informal creative labour in a transitional cultural economy (the case of privately funded Moscow art centres)
Authors: Kuleva Margarita I
Published: January 2019

This article investigates the creative work that is now taking place in newly established cultural institutions in Moscow, the non-governmental museums of contemporary art (MoCAs). The exploration of creative work in Russian art centres is of particular interest because it promises to record the transition of the contemporary art market from the Soviet-era cultural monopoly to the market economy, during the real-time formation of new, informal standards of cultural production. The present article evaluates what informality means within these new standards of the organization of creative work: while standing for culture ‘in a new and innovative way’, the new art centres preserve many residues of the ‘old system’, such as the practices of blat, favour-swapping and clientelism. The article is based on an empirical study conducted in 2016 which included 25 in-depth interviews with cultural workers employed full-time, and 20 live observations in offices and exhibition areas of the art centres.
Reducing stress: Social support and group identification
Authors: McKimmie Blake M. , Butler Tamara , Chan Edward , Rogers Allira , Jimmieson Nerina L.
Published: January 2019

Three studies systematically explored the relationship between social support and group identification in the context of how individuals cope with stress. In Study 1, 101 participants took part in a simulated group task where they either received social support or not under conditions of either high or low demand. Social support was associated with higher group identification, and this mediated the effect of social support on more positive appraisals and task satisfaction. In Study 2, 83 participants were either made aware of their group membership or worked as individuals on a group task under high or low demand. In this study, group membership salience was associated with greater perceived support, which was associated with greater group identification, and subsequently more positive primary and secondary appraisals, more problem-focused coping, and task satisfaction. Study 3 assessed the perceived social support and group identification reported by 71 volleyball team members before and after a game. Results were more consistent with the notion that support and identification were two concurrent perceptions associated with being in a group, rather than identification priming the recognition of support or support increasing identification.
Computer-aided sensitivity analysis of a multicriteria decision-making methodology for the evaluation of materials requirements stringency in the nuclear components manufacturing
Authors: Rodríguez-Prieto Álvaro , Camacho Ana M , Yanguas-Gil Ángel , Sebastián Miguel A
Published: January 2019

A methodology developed specifically for the evaluation of requirements of materials intended to high-demanding applications is the stringency levels methodology. The objective of this work is to perform a sensitivity analysis of the methodology of multicriteria stringency levels for the evaluation of technological requirements of materials, creating a new methodology that provides a final results studying variability that let us make an objective decision. The case study has been the evaluation of steels used in the manufacture of components housed in the primary loop of a nuclear power plant. To ease the calculation of the stringency levels, the algorithm has been computed in Labview®. Considering the dispersion that can generate the numerical weighting process, the analysis has shown that the variability in calculated values is not significant. The analysis proposed with this methodology could be used, in the future, for the selection of materials for innovative manufacturing processes.
The presentation of brand personality in English-Chinese brand name translation
Authors: Cui Ying
Published: January 2019

The brand name is an important asset of a business, for consumers rely on brand names to identify goods for purchase. English-Chinese brand name translation is of significance as it influences how a brand is received in China, which has become one of the largest consumer markets in the world. Brand names often cause consumers’ emotional response to enhance their memory, establish positive images about the brands, and serve the purpose of promotion. This paper discusses the issue of emotional involvement in English-Chinese brand name translation via discourse analysis and exploration of the presentation of brand personality in translation. The causes for and types of emotional involvement are investigated with reference to studies on brand personality which can invoke consumers’ emotional response and play a key role in enhancing consumers’ loyalty to and trust of a brand, and a revised framework of brand personality for Chinese brand name translations is provided on the basis of current research on English and Chinese brand personality, as well as analysis and classification of the brands in our corpus. The examples in our corpus are analyzed according to this framework, and the features of emotional involvement in the Chinese translations are summarized and discussed.
How eWord of Mouth valences affect price perceptions
Authors: Liang Wai Ki , Corkindale David
Published: January 2019

The influence of electronic Word of Mouth (eWOM) on consumers’ perceptions of price, allowing for consumers having different price acceptability levels, was examined through nine online experiments. Three valences of eWOM were systematically examined: positive, negative, and inconsistent, that is, both positive and negative present in the word-of-mouth communication. When contemplating making a purchase of an item, consumers have ranges of prices that would be acceptable. It was found that eWOM was more influential on consumers’ price perceptions than the advertised price for all price acceptability levels. However, the price perception of an item was found to be less acceptable when eWOM was inconsistent compared to when eWOM was absent or was positive. Inconsistent eWOM had a negative effect on price perceptions but not as great as that when negative eWOM was present and this was consistently found to apply for all price acceptability levels. The market context for the experiments was that of a tourism service, a Group Package Tour in Japan. We present the study’s implications for practitioners in this type of market, as well as the contribution to the research literature on word-of-mouth influence on consumer response to prices.

Introduction:

The purpose of the current study was to investigate the periprocedural and long-term outcomes of stent implantation for de novo subclavian artery (SCA) disease.

Material and Methods:

We retrospectively investigated consecutive patients with de novo SCA lesions undergoing elective endovascular therapy procedures at our center between April 2004 and September 2015. All patients were included in the analyses of periprocedural outcomes, including procedural and clinical success. Subsequently, patients who completed the clinical follow-up and were assessed with brachial systolic pressure differences between the diseased and the contralateral arms, or angiographic stenosis, after stent implantation with procedural success were included in the analyses of long-term outcomes, including primary patency.

Results:

There were 62 patients (median 71.0 years, interquartile range 65.3-76.0 years; 45 men) with 62 de novo SCA lesions included in the analyses of periprocedural outcomes. There were 46 stenoses (74.2%) and 16 occlusions (25.8%). Our results indicated high procedural success rates for overall (95.2%), stenotic (97.8%), and occlusive (87.5%) lesions. Similarly, high clinical success rates were observed for overall (91.9%), stenotic (93.5%), and occlusive (87.5%) lesions. The median follow-up time was 6.0 years (interquartile range, 2.6-8.3 years). There were 48 patients with 48 de novo SCA lesions included in the analyses of long-term outcomes. Primary patency estimates were 97.7% (1 year), 97.7% (3 years), 93.1% (5 years), and 87.6% (7 years). Also, we observed a high estimate for freedom from reintervention for the target vessel (93.8%).

Conclusion:

Stent implantation for de novo SCA disease can be performed successfully and safely with favorable periprocedural and long-term outcomes.

To predict the manoeuvrability of unmanned marine vehicle and improve its manoeuvrability, the parameters of the manoeuvring model of unmanned marine vehicle need to be obtained. Aiming at the inconvenience of obtaining model parameters under the traditional experimental method, this article studies the parameter identification of unmanned marine vehicle’s manoeuvring model based on extended Kalman filter and support vector machine. Firstly, the second-order nonlinear manoeuvring response model of unmanned marine vehicle is discretized by the difference method, and the corresponding data are collected by the manoeuvring motion simulation of the response model. Secondly, the discrete response model is transformed into an augmented state vector based on extended Kalman filter, and the optimal estimation of the state vector is calculated to identify the parameters. And then, the discrete response model is transformed into a support vector machine-based regression model, the collected data are processed and a set of support vectors are obtained to further identify the parameters of the response model. Finally, by comparing the simulation experiments’ results from the original model and the identification model, the recognition results-based extended Kalman filter and support vector machine are analysed and some research results are obtained. The results of this article will provide a powerful reference for the design of unmanned marine vehicle’s motion control algorithm.
How news media (de-)legitimize national and international climate politics – A content analysis of newspaper coverage in five countries

Published: January 2019

Implementing global climate change policies on the national and sub-national level requires the support of many societal actors. This support depends on the perceived legitimacy of climate policies, which can be sustained by legitimation debates in domestic news media. This article analyses legitimation statements on climate politics in newspapers of five countries for three Conferences of the Parties in 2004, 2009 and 2014 ( n = 369 legitimation statements). According to our data, it is mainly the legitimacy of international climate policies (instead of national ones) which is evaluated in national fora, and it is usually portrayed negatively. However, there is a noticeable shift in the arguments used over our 10-year period of analysis, moving from efficiency as the dominating evaluation criterion to questions of fairness in the distribution of costs and gains.
Improvement of lung function and pulmonary hypertension after pulmonary aneurysm repair: case series

Published: January 2019

Pulmonary artery aneurysms (PAA) can be complicated with pulmonary arterial hypertension (PAH), causing sudden death due to PA rupture and dissection. Because treatment with PAH‐targeted drugs does not always prevent PAA progression, prophylactic surgical repair of the PAA seems a promising alternative. However, although it avoids rupture and dissection of the PAs, additional benefits have not been forthcoming. We therefore present two patients with co‐existing PAH and a PAA who underwent surgical repair of the aneurysm. Following the surgery, their lung function and pulmonary hypertension improved. Optimal treatment of PAA remains uncertain, however, with no clear guidelines regarding the best therapeutic approach. This case series provides physicians with reasons to repair PAA surgically in patients with PAH.

Background

The early diagnosis of cardiac abnormalities in young athletes may be helpful not only to identify subjects potentially at risk of sudden cardiac death but also to prevent stress-related cardiac dysfunction and cardiovascular events during the life of these subjects. The aim of our study was to investigate the prevalence of cardiac abnormalities in a population of young male soccer players undergoing pre-participation screening through electrocardiogram and trans-thoracic echocardiography.

Methods

All consecutive male football players undergoing pre-participation screening comprehensive of medical history, physical examination, 12-lead electrocardiogram and trans-thoracic echocardiography at the FMSI Sport Medicine Institute in Rome between January 2008–March 2009 were enrolled in the study.

Results

Overall, 2261 consecutive young athletes aged 12.4 ± 2.6 years were evaluated. Training-unrelated electrocardiogram abnormalities were observed in 65 (2.9%) athletes. Abnormal trans-thoracic echocardiography was observed in 102 athletes (4.5%), including two cases of hypertrophic cardiomyopathy, eight of mild left ventricular hypertrophy, six of mild left ventricular dilation and 17 of bicuspid aortic valve. An abnormal electrocardiogram was associated with anomalous trans-thoracic echocardiography in 11/65 (16.9%) cases. All athletes requiring sport disqualification were identified by electrocardiogram. Notably, among 2216 athletes with a normal electrocardiogram, 91 had abnormal trans-thoracic echocardiography, including six cases of left ventricular dilation and six of ventricular hypertrophy.

Conclusions

In a wide population of peri-pubertal male athletes, evaluation of the electrocardiogram identified all cardiac diseases requiring sport disqualification. Trans-thoracic echocardiography alone allowed the identification of cardiac abnormalities potentially leading to cardiomyopathies or major cardiovascular events over time.
