Authors: Ramaraj Akila , Jensen Guy , Rice-Townsend Samuel , DiGeronimo Robert , Yalon Larissa , Stark Rebecca
Published: July 2021

Purpose:

Complications associated with use of dual-lumen venovenous extracorporeal membrane oxygenation (VV-ECMO) cannulas are of concern in pediatric patients. While the risk of atrial perforation is believed to be higher with bicaval cannulas, direct comparison of complication rate between atrial and bicaval cannulas has not been conducted in this population.

Methods:

A retrospective review was conducted at a free-standing children’s hospital of all patients 0–18 years old, placed on VV-ECMO with a dual-lumen cannula from January 2009 to December 2018. Patients were grouped based on cannula type. Complications were assessed over the entire duration of the ECMO run. Logistic regression analyses were used to evaluate for an association between cannula type and risk of pericardial effusion or cannula-related complication requiring median sternotomy or pericardial drain placement.

Results:

During the study period 119 patients were placed on VVECMO using a dual-lumen cannula. Eighty-two patients (69%) were <2 years old, 19 (16%) were 2–10 years old, and 18 (15%) were 11–18 years old. Seventy-three were cannulated with an atrial cannula and 46 patients received a bicaval cannula. Pericardial effusions were seen in 30% and 24% of these patients respectively while severe complications were seen in 9.6% and 8.7% of patients respectively. Compared to patients treated with a bicaval cannula, those who received an atrial cannula had similar odds of effusions (OR: 1.41, 95% CI: 0.62–3.36) and severe complications (OR 0.89, 95% CI: 0.27–3.18). After adjusting for age, weight, cannula and circuit manipulations, and use of echocardiography, the OR of effusion was 1.91 (95% CI: 0.65–6.42), and the adjusted OR of severe complication was 0.69 (95% CI: 0.16–3.33).

Conclusions:

There were no significant differences in frequency of pericardial effusions or severe cannula-related complications between the treatment groups across all pediatric patients and within the subgroup of patients under 2 years of age.
Community Health Education for Health Crisis Management: The Case of COVID-19 in Cameroon
Authors: Mbah Marcellus , Bang Henry , Ndi Humphrey , Ndzo Judwin Alieh
Published: July 2021

The current coronavirus disease 2019 (COVID-19) pandemic has led Cameroon’s government to implement public health measures aimed at preventing its spread. This paper investigates how community health education on the virus was being carried out, what gaps exist and what further action could be taken. A survey instrument was used to gather data among a total of 179 Cameroonians recruited via opportunistic and snowball sampling methods. According to our findings, gaps exist. These include the need for adequate community health education on COVID-19, maximising multilingualism and indigenous cultural assets and disbanding misconceptions on the pandemic, as well as stigmatisation. The paper culminates by underlining the significance of an integrated approach to confront the pandemic. This approach captures the need to frame but also firm up community health education architecture on COVID-19 that captures inputs from different stakeholders, including indigenous knowledge holders, for collective wellbeing.

Published: July 2021

Relatively little is known about readiness of urban health systems to address health needs of the poor. This study explored stakeholders’ perception of health needs and strategies for improving health of the urban poor using qualitative analysis. Focus group discussions (n = 5) were held with 26 stakeholders drawn from two Nigerian states during a workshop. Urban areas are characterised by double burden of diseases. Poor housing, lack of basic amenities, poverty, and poor access to information are determinants of health of the urban poor. Shortage of health workers, stock-out of medicines, high cost of care, lack of clinical practice guidelines, and dual practice constrain access to primary health services. An overarching strategy, that prioritises community-driven urban planning, health-in-all policies, structured linkages between informal and formal providers, financial protection schemes, and strengthening of primary health care system, is required to address health needs of the urban poor.
Delayed diagnosis of critical congenital heart defects predicting risk factors and survival rate in newborns in Beijing: a retrospective study
Authors: Zhang Wen , Xu Hong-Yan , Zhang Yan-Chun , Liu Kai-Bo
Published: July 2021

Objective

To assess the prevalence and survival rate of newborns with a delayed diagnosis of critical congenital heart defects (CCHD) in Beijing.

Methods

This retrospective study analysed data from births between 2010 and 2017 from the Birth Defects Monitoring Network in Beijing. Newborns with CCHD were analysed according to seven categories. Statistical analyses were used to calculate the mortality rate within the first week (days 0–6) after live birth. Multivariate logistic regression analysis of survival was performed to analyse the potential risk factors for newborn mortality.

Results

A total of 1 773 935 perinatal newborns were screened in Beijing and 1851 newborns were diagnosed with CCHD, showing a prevalence of 10.43 per 10 000. Among the total 1851 CCHD patients, the majority (1692 of 1851; 91.41%) were identified through prenatal diagnosis, 104 of 1851 (5.62%) were diagnosed before obstetric discharge/transfer and 55 of 1851 (2.97%) were identified through delayed diagnosis. The prevalence of CCHD in newborns was 1.96 per 10 000 births. Multivariate logistic regression analysis of survival demonstrated that gestational age at delivery was the only risk factor for death within the first week after birth.

Conclusions

Within the first week after birth, gestational age was the only risk factor for death in newborns with CCHD.
Functional status in postural tachycardia syndrome
Authors: Rich Emily M , Vas Asha , Parsons Thomas D , Krone Ryan , Goodman Brent P
Published: July 2021

Introduction

Postural tachycardia syndrome is a form of orthostatic intolerance that often leads to functional impairment.

Methods

This survey explored functional status and impact of symptoms in adults ( n = 958) ages 18 to 60 (M = 32.63 ± 10.52 years, 96.7% female) with postural tachycardia syndrome.

Results

Individuals reported an average of 11 daily life activities impacted by postural tachycardia syndrome with high levels of self-perceived disability. Additionally, 93.4% reported some degree of cognitive impairment and falls occurred in 55.3% of participants annually. Despite frequent falls and functional impairment, participants infrequently (26.9%) utilized therapy services.

Conclusion

Individuals with postural tachycardia syndrome are at an increased risk of experiencing disability and often require assistance with daily activities. Further research is necessary to understand the potential role of therapy in improving function and quality of life.
Searching for tūpuna
Authors: Andrews Nicola
Published: July 2021

The Burke Museum of Natural History and Culture opened the “Pacific Voices” exhibition in 1997, a community-led exhibition of Indigenous cultures throughout the Pacific Rim, including Māori. Twenty years later, Nicola Andrews, a Ngāti Pāoa Māori student at the University of Washington, serendipitously visited the Burke and began collaborating with the museum to reframe taonga (treasure, anything prized) descriptions in its catalogue and physical spaces. The Burke collection also includes 962 Māori photographs spanning the 19th century, which were removed from Aotearoa New Zealand and donated to the museum in 1953. These photographs had been digitized but not published, and the museum had almost no identifying information about their subjects. This article describes what is perhaps the first attempt in over six decades to identify the rangatira (chief, person of high rank) depicted in these images, and ways for the Burke to honor the tūpuna (ancestors) and taonga in its care as it prepared to open a new location in late 2019.
Work-Life-Study Balance and Executive Education: Case of India
Authors: Sharma Anshu , Mor Surender , Garg Ruchi , Chhikara Ritu , Pal Amit , Narula Sanjiv
Published: July 2021

This article aims to understand the unique phenomenon of the work-life-study interface by studying the lived-in experiences of executive education students qualitatively. It delivers a unique contribution by highlighting the third element of ‘study’ in Work-life balance (WLB), unlike most of the literature, which is skewed towards work-life balance and neglects the ‘study’ aspect. The study used phenomenology as the qualitative research method to explore the work-life-study balance of 25 executive education students working in middle-level positions, employing the purposive sampling technique for the year 2020. The findings reveal positive and negative experiences of work-life balance phenomena among executive education students. The results further provide a real-time sneak peek into an executive education scholar’s life and hence, may be used as a point of reference for mental mapping before opting for executive education courses. The study advocates interventions to support executives wishing to re-skill themselves in mid-careers and manage emotions, stress, and burnout.
Raising the bar? The impact of the UNISON ethical care campaign in UK domiciliary care
Authors: Johnson Mathew , Rubery Jill , Egan Matthew
Published: July 2021

This article critically analyses a major trade union initiative in the United Kingdom to raise standards in public contracts for domiciliary care, and in turn to improve wages and working conditions for outsourced care workers. The campaign successfully built alliances with national employer representatives, and around 25 per cent of commissioning bodies in England, Scotland and Wales have signed a voluntary charter that guarantees workers an hourly living wage, payment for travel time and regular working hours. The campaign overall, however, has had only limited effects on standards across the sector, in which low wages, zero-hours contracts and weak career paths predominate. Furthermore, the campaign has not yet yielded significant gains in terms of union recruitment, although there are signs of sporadic mobilisations of care workers in response to localised disputes.
State Guardianship Laws and Supported Decision-Making in the United States After Ross and Ross v. Hatch: Analysis and Implications for Research, Policy, Education, and Advocacy
Authors: Martinis Jonathan , Harris Jason , Fox Dean , Blanck Peter
Published: July 2021

In the last decade, and especially after the 2013 Virginia court case of Ross and Ross v. Hatch, there has been a dramatic increase in knowledge, use, and legal recognition of supported decision-making (SDM) in the United States. SDM is a methodology in which people work with trusted friends, family members, and professionals who help them understand their situations and choices so they may make their own decisions and direct their lives. After the Hatch case, in which a young woman with Down syndrome defeated a petition for permanent guardianship by demonstrating that she uses SDM, this methodology has increasingly been considered and used as an alternative to guardianship to enable people to retain their legal rights and make life choices to the maximum extent possible. This article reviews the guardianship laws of the 50 U.S. states and the District of Columbia. Using criteria we developed, in light of the findings and values expressed in Hatch, we assessed the extent to which those laws recognize or encourage the use of SDM as an alternative to guardianship and as a means to enhance self-determination for people in guardianship. We then offer recommendations for future SDM research, policy, education, and advocacy efforts.
Speech Outcome and Self-Reported Communicative Ability in Young Adults Born With Unilateral Cleft Lip and Palate: Comparing Long-Term Results After 2 Different Surgical Methods for Palatal Repair
Authors: Peterson Petra , Nyberg Jill , Persson Christina , Mark Hans , Lohmander Anette
Published: July 2021

Objective:

To compare speech outcome and self-reported speech and communicative ability (SOK) in young adults treated with one-stage (OS) or two-stage (TS) palatal repair. Furthermore, to compare with normative data on individuals without cleft lip and palate and to study the relationship between patients’ and experts’ judgments.

Design:

A cross-sectional group comparison study with long-term follow-up. Participants: Patients born with unilateral cleft lip and palate treated at 2 cleft centers; 17 with OS at 14 months and 25 with TS, soft palate repair at 7 months and hard palate repair at 6.2 years. Pharyngeal flap surgery was performed in 53% (OS) and 24% (TS) of patients.

Main Outcome Measure(s):

Speech characteristics were blindly assessed by speech and language pathologist from audio recordings, SOK at 19 years of age.

Results:

No group differences were found. Although the occurrence of nasality symptoms was low in both groups, only 60% (OS)/65% (TS) were assessed with competent velopharyngeal function (VPC). Articulation proficiency (percentage of consonants correct [PCC]) was 91%/97%, the /s/-sound specifically 87%/91%. Good intelligibility was found in 91%/87%. Patient opinion was in agreement with norms and significantly associated with intelligibility ( rs = 0.436, P < .01), PCC ( rs = −0.534, P < .01), and correct /s/ ( rs = −0.354, P < .05).

Conclusions:

No differences in speech outcome were related to operation method. The low prevalence of VPC was not clearly reflected in nasality symptoms. Patient opinion was related to articulation and intelligibility. A higher burden of care in terms of pharyngeal flap surgery was seen after the OS technique.
Resilience and Parental Burnout Among Finnish Parents During the COVID-19 Pandemic: Variable and Person-Oriented Approaches
Authors: Sorkkila Matilda , Aunola Kaisa
Published: July 2021

During the coronavirus disease 2019 (COVID-19) crisis, different personality characteristics may have influenced parental well-being in different ways. In the present study, we combined variable and person-oriented approaches and examined relationships between resilience, parental burnout, and perfectionism during the lockdown. We first used structural equation modeling to assess the paths between variables. We then used latent profile analysis to examine different profiles of parents based on resilience, perfectionism, and symptoms of parental burnout. Finally, we examined how these profiles differ in terms of relevant background variables. The results showed that resilience predicted parental burnout negatively even after controlling for multidimensional perfectionism. Parents’ age, children's age, children's special needs, and the increase in time spent with children due to lockdown contributed independently to burning out as a parent. Three profiles were found: a resilient profile, perfectionist profile, and burned-out profile. Resilient parents were likely to be men, older, and with less financial difficulties than parents in the other two profiles, and less likely to spend increased time with their children due to lockdown than the burned-out parents. Perfectionist parents, in turn, had older children than the burned-out parents did. These results suggest that resilience may help parents overcome burnout at times of crisis.
Validation of Work Need Satisfaction Scales Among Chinese Working Adults: A Psychology of Working Theory Perspective
Authors: Xu Yan , Li Chaoping , Wang Jiayan , Lan Yuanmei
Published: July 2021

This study translated the Work Need Satisfaction Scales (WNSS), which was conceptualized in the Psychology of Working Theory (PWT), and tested the reliability and validity of the Chinese version (WNSS-C). In Study 1 ( N = 423), the WNSS was translated into Chinese, and an exploratory factor analysis yielded a five-factor solution representing needs related to survival, social contribution, competence, relatedness, and autonomy. In Study 2 ( N = 425), confirmatory factor analyses found no significant differences between the correlated five-factor, higher-order, and higher-order self-determination needs models. The results suggest the effectiveness of using a flexible five-factor model. Then, configural, metric, and scalar invariance models were tested, demonstrating that the WNSS-C is equivalent across gender, age, education level, and job position. Finally, we tested the concurrent, convergent, and discriminant validity of the WNSS-C and demonstrated that WNSS-C is a useful tool in the Chinese context.
The Role of Pyroptosis in Ischemic and Reperfusion Injury of the Heart

Published: July 2021

While ischemia itself can kill heart muscle, much of the infarction after a transient period of coronary artery occlusion has been found to result from injury during reperfusion. Here we review the role of inflammation and possible pyroptosis in myocardial reperfusion injury. Current evidence suggests pyroptosis’s contribution to infarction may be considerable. Pyroptosis occurs when inflammasomes activate caspases that in turn cleave off an N-terminal fragment of gasdermin D. This active fragment makes large pores in the cell membrane thus killing the cell. Inhibition of inflammation enhances cardiac tolerance to ischemia and reperfusion injury. Stimulation of the purinergic P2X7 receptor and the β-adrenergic receptor and activation of nuclear factor κ-light-chain-enhancer of activated B cells (NF-κB) by toll-like receptor (TLR) agonists are all known to contribute to ischemia/reperfusion (I/R) cardiac injury through inflammation, potentially by pyroptosis. In contrast, stimulation of the cannabinoid CB2 receptor reduces I/R cardiac injury and inhibits this pathway. MicroRNAs, Akt, the phosphate and tension homology deleted on chromosome 10 protein (PTEN), pyruvate dehydrogenase and sirtuin-1 reportedly modulate inflammation in cardiomyocytes during I/R. Cryopyrin and caspase-1/4 inhibitors are reported to increase cardiac tolerance to ischemic and reperfusion cardiac injury, presumably by suppressing inflammasome-dependent inflammation. The ambiguity surrounding the role of pyroptosis in reperfusion injury arises because caspase-1 also activates cytotoxic interleukins and proteolytically degrades a surprisingly large number of cytosolic enzymes in addition to activating gasdermin D.
Implications of a Mortgage Interest Credit for the United States
Authors: Drukker Austin J.
Published: July 2021

The US mortgage interest deduction (MID) allows homeowners to deduct the interest paid on their mortgages from their federal tax returns, provided that they itemize deductions. Since the benefit depends on a taxpayer’s marginal tax rate, which increases with income, the MID is an “upside-down subsidy” that becomes more valuable for higher-income homeowners. I analyze the implications of converting the US MID to a mortgage interest credit (MIC) and evaluate the effects on federal revenue and the distribution of income. I argue that a MIC could be better targeted at low- and middle-income taxpayers on the margin of homeownership while also being more progressive and less expensive than the current MID.
Masquerading the Government: Drivers of Government Impersonation Fraud
Authors: Goel Rajeev K.
Published: July 2021

This article uniquely examines the drivers of government impersonation across US states. Government impersonation is a relatively new white-collar crime that is slowly being recognized by policy makers and largely ignored by researchers. Results show that it is the decentralized government structure, rather than government size, that significantly affects government impersonation. Greater diffusion of the Internet and economic freedom also contribute to impersonation fraud, while urbanization has a mitigating effect. The share of elderly residents, democratic governorships, or the distance of a state from the nation’s capital did not appreciably impact government impersonation but impacted overall fraud. Interestingly, greater enforcement employment results in more fraud coming to light. Some of the factors impacting government impersonation fraud differ from those affecting overall fraud. Therefore, blanket policies to combat overall fraud would not necessarily be effective in checking government impersonation.
Understanding Evaluation Policy and Organizational Capacity for Evaluation: An Interview Study
Authors: Al Hudib Hind , Cousins J. Bradley
Published: July 2021

Evaluation policy has been identified as an important means of shaping and influencing organizational evaluation practice, yet, to date, little empirical research has been conducted to deepen our understanding of this relationship. The purpose of this study was to illuminate evaluation policy’s role in leveraging organizational capacity to do and use evaluation. We interviewed 18 published evaluation scholars and practitioners from North America and Europe about this topic. A thematic analysis of findings underscores the importance of context, policy attributes, enablers, and organizational benefits. Based on the findings, we developed an ecological conceptual framework to guide thinking about the role of evaluation policy in capacity building. We discuss these findings in terms of practical implications of understanding context, redressing the imbalance between learning and accountability purposes of evaluation, and organizational leadership, and we conclude with some implications for research.
Supportive assessment strategies as curriculum events in a performance-oriented classroom context
Authors: Vogt Bettina
Published: July 2021

This article examines the role and pedagogical implications of supportive assessment strategies at the interface where curriculum, general Didaktik and pedagogy meet; theoretically, the article draws upon concepts from research in each of those domains. This interplay is examined in relation to the performance-orientation on two curricular levels: on the programmatic curriculum level, Sweden is used as an example for a result-oriented curricular assessment context. On the enacted curriculum level, a high-performing class in year 8 in a Swedish compulsory school is chosen as a concrete case. Methodologically, the study represents a classroom case study. The empirical data corpus has been collected during one school year and consists of video-recorded lesson observations in the subjects of Swedish and science, semi-structured interviews with teachers and students, and field notes and teaching artefacts in the form of teaching documents. The results show that the supportive assessment strategies used in this classroom context can be understood as a kind of catalyst for the curricular performance orientation, where the effective achievement of externally set up outcome expectations is the purpose. Finally, this is critically discussed, among others, in relation to a bildungs-oriented understanding of education.
Techniques of corrosion monitoring of steel rebar in reinforced concrete structures: A review
Authors: Fan Liang , Shi Xianming
Published: July 2021

Reinforcement corrosion is a major culprit that undermines the service life of reinforced concrete (RC) structures. It costs billions of dollars each year in the US alone and negatively impacts safety, reliability, resilience, and environmental performance of RC infrastructure. Corrosion monitoring of steel rebar is critical to provide early warning of deficiency, enable timely and effective maintenance strategies, and prevent catastrophes associated with premature failure of RC structures. To improve corrosion monitoring in the engineering practice, this work comprehensively reviews the state of the art of five major types of techniques, that is, electrochemical sensors, optical fiber sensors, sensors based on elastic wave methods, sensing based on electromagnetic methods, and untouched sensors. Each type of technique is systematically divided into sub-categories based on the sensing principle and key characteristics. For each sensor type, its maturity, application range, and the problems that hinder its application are discussed, aimed to provide guidance in selecting the appropriate sensors for specific engineering applications. This work concludes with an overview of opportunities and challenges, including the following six aspects for future research: spatial resolution, sensitivity, and measurement range; reliability and interpretation of the measurement; sensor selection based on three corrosion stages of steel rebar; long-term stability and service life; cost-efficiency of the sensing system; and monitoring of existing structure.
Moral Judgment as Categorization (MJAC)
Authors: McHugh Cillian , McGann Marek , Igou Eric R. , Kinsella Elaine L.
Published: July 2021

Observed variability and complexity of judgments of “right” and “wrong” cannot be readily accounted for within extant approaches to understanding moral judgment. In response to this challenge, we present a novel perspective on categorization in moral judgment. Moral judgment as categorization (MJAC) incorporates principles of category formation research while addressing key challenges of existing approaches to moral judgment. People develop skills in making context-relevant categorizations. They learn that various objects (events, behaviors, people, etc.) can be categorized as morally right or wrong. Repetition and rehearsal result in reliable, habitualized categorizations. According to this skill-formation account of moral categorization, the learning and the habitualization of the forming of moral categories occur within goal-directed activity that is sensitive to various contextual influences. By allowing for the complexity of moral judgments, MJAC offers greater explanatory power than existing approaches while also providing opportunities for a diverse range of new research questions.
Hanna-Barbera’s Cacophony: Sound Effects and the Production of Movement
Authors: Sullivan Patrick
Published: July 2021

Zaps, crashes, boinks, and bangs flooded TV’s airwaves with the rise of Hanna-Barbera Productions at the end of the 1950s, and these sound effects have been heard ever since. Hanna-Barbera Productions created and proliferated one of the most recognizable collections of sounds in television and animation history. This article traces the formation of Hanna-Barbera’s library of sound effects and how these sound effects operate within the studio’s cartoons. Motored by television’s demanding production schedule and restrictive budgets, Hanna-Barbera persistently recycled its sound effects across episodes, seasons, and series. These sound effects, heard over and over again, were paired to the studio’s brand of limited animation – a form of animation that is often seen as kinetically wanting – to enliven images through sonically invoking movement, what this article calls trajectory mimesis. This logic of trajectory mimesis facilitates the repetition of the studio’s sound effects. These conditions – television’s economic restraints and the studio’s limited animation aesthetics –provided the ideal conditions for the creation of Hanna-Barbera’s iconic library of sound effects.
Extending the Participant’s Voice to Guide Artificial Intelligence Transformation Using Futures Methodology and Layered User Story Analysis
Authors: Farrow Elissa
Published: July 2021

Artificial intelligence (AI) is a vital driver of the next wave of automatisation of Industry 4.0. It impacts product-based and service-based organisations and is becoming an investment stream in organisational transformation strategies. The transformation teams that deploy AI use agile incremental methodologies that ideally match the learning and adaptation requirements for the machine, as well as the human user who is the source of data and requires a service response. This research outlines a layered analysis process of 65 user stories (a common agile method of obtaining user requirements) generated via a participatory process, involving 110 participants in three workshop settings, in what they determined AI would not do. The results outline the workshop approach undertaken to generate user stories and the analysis of user stories via persona and futures methodology causal layered analysis (Inayatullah S. 1998. Causal layered analysis. Futures 30(8): 815-829). The final component of the analysis generated a futures focussed set of guiding principles that can be used as a lens to broaden the transformation teams perspective in AI deployment. Concepts also consider the importance of futures literacy as a key competency of AI creation teams.
Eighty Percent Survival of Resurfacing Implants in the Knee After 10 Years: A Nationwide Cohort Study on 379 Procedures from the Danish Knee Arthroplasty Registry
Authors: Christensen Bjørn B. , El-Galaly Anders , Laursen Jens Ole , Lind Martin
Published: July 2021

Objective

Focal cartilage injuries are debilitating and difficult to treat. Biological cartilage repair procedures are used for patients younger than 40 years, and knee arthroplasties are generally reserved for patients older than 60 years. Resurfacing implants are well suited for patients in this treatment gap. The objective was to investigate the 10-year survival of resurfacing implants in the Danish Knee Arthroplasty Registry.

Design

In this retrospective cohort study, patients treated with resurfacing implants were followed longitudinally in the Danish Knee Arthroplasty Registry from 1997 to 2020. The primary endpoint was revision surgery. The survival of the resurfacing implants was analyzed by Kaplan-Meier method.

Results

A total of 379 resurfacing implant procedures were retrieved from the Danish Knee Arthroplasty Registry. The mean age and weight of patients were 50 years (SD = 11) and 84 kg (SD = 17), respectively. The indications for surgery were as follows: secondary osteoarthritis (42%), primary osteoarthritis (32%), and osteochondral lesions (20%). Within the follow-up period, 70 (19%) of the implants were revised to arthroplasties. The 1-, 5-, and 10-year revision-free survival estimation was 0.95 (95% CI 0.93-0.97), 0.84 (95% CI 0.80-0.88), and 0.80 (95% CI 0.75-0.84), respectively. The median time to revision was 2 years.

Conclusion

The 10-year revision-free survival rate for resurfacing implants was 80%. Based on the revision rates, this treatment offers a viable alternative to biological cartilage repair methods in patients aged 40 to 60 years with focal cartilage pathology. Improved patient selection could further improve the implant survival rate. Further studies are needed to investigate this treatment method.
Digital detox: An effective solution in the smartphone era? A systematic literature review
Authors: Radtke Theda , Apel Theresa , Schenkel Konstantin , Keller Jan , von Lindern Eike
Published: July 2021

Smartphone use, e.g., on social network sites or instant messaging, can impair well-being and is related to clinical phenomena, like depression. Digital detox interventions have been suggested as a solution to reduce negative impacts from smartphone use on outcomes like well-being or social relationships. Digital detox is defined as timeouts from using electronic devices (e.g., smartphones), either completely or for specific subsets of smartphone use. However, until now, it has been unclear whether digital detox interventions are effective at promoting a healthy way of life in the digital era. This systematic literature review aimed to answer the question of whether digital detox interventions are effective at improving outcomes like health and well-being, social relationships, self-control or performance. Systematic searches of seven databases were carried out according to PRISMA guidelines, and intervention studies were extracted that examined timeouts from smartphone use and/or smartphone-related use of social network sites and instant messaging. The review yielded k = 21 extracted studies (total N = 3,625 participants). The studies included interventions in the field, from which 12 were identified as randomized controlled trials. The results showed that the effects from digital detox interventions varied across studies on health and well-being, social relationships, self-control, or performance. For example, some studies found positive intervention effects, whereas others found no effect or even negative consequences for well-being. Reasons for these mixed findings are discussed. Research is needed to examine mechanisms of change to derive implications for the development of successful digital detox interventions.
‘I wish my body was stronger’: A qualitative study of attitudes and behaviours regarding treatment of hypertensive disorders of pregnancy
Authors: Helou Amyna , Stewart Kay , Ryan Kath , George Johnson
Published: July 2021

Objectives:

To investigate pregnant women’s attitudes and behaviours towards hypertensive disorders of pregnancy and their treatment.

Methods:

Face-to-face, in-depth interviews were undertaken with 27 pregnant women diagnosed with and being treated for hypertensive disorders of pregnancy to investigate attitudes and behaviours regarding the conditions and their treatment. Written consent was obtained individually from each participant, and the interviews ranged from 16 to 54 minutes. Data collection was continued until thematic saturation was reached. Thematic analysis was employed to interpret the data.

Results:

Four major themes emerged around beliefs and behaviours of pregnant women regarding treatment of their hypertension: understanding of hypertensive disorders of pregnancy and their implications, risks versus benefits of antihypertensive medication during pregnancy, trust in medical professionals and adherence to medication. The women’s level of understanding of hypertensive disorders of pregnancy and their implications determined whether they were able to make informed decisions about their treatment. Prior experiences and concern for preservation of the pregnancy played major roles in the perception of the risk/benefit balance of using antihypertensive medication during pregnancy. The degree of trust in the treating medical professionals varied according to the perception of their confidence and knowledge.

Conclusions:

Sound understanding of the condition, a positive risk/benefit balance regarding antihypertensive medication use during pregnancy, and trust in medical professionals contributed to adherence to medication. Good communication with healthcare professionals is important to achieve optimal treatment.
How policy influence varies with race and gender in the US courts of appeals
Authors: Hinkle Rachael K.
Published: July 2021

Even when women and people of color achieve positions of political power, institutional norms may combine with social constructions of difference to create a system in which power is distributed disproportionately. Such a pattern is evident in the US courts of appeals. Each case is resolved by a panel of three judges who also decide whether the opinion should be binding precedent (i.e., published) or not. I theorized that the variety of views and extended deliberation often attributed to diversity in a small-group environment depressed the rate of publication if judges were willing to compromise on the outcome but less willing to publish an opinion after such compromise. Using a massive original dataset of virtually all dispositive circuit opinions from 2002 to 2012, I found that homogeneous panels (98% of which are composed of white men) shaped policy more frequently than diverse panels.
Ventilatory failure in a cat following radical chest wall resection for feline injection site sarcoma
Authors: Bilko Samantha J , Veytsman Stan , Amsellem Pierre M , Chow Rosalind S
Published: July 2021

Case summary

A 12-year-old spayed female domestic shorthair cat presented for chest wall resection and radiation therapy following incomplete surgical excision of a feline injection site sarcoma. A CT scan for surgical planning was performed under general anesthesia and showed extensive tumor infiltration of the soft tissues of the right thorax. The cat recovered uneventfully from this anesthetic event. Nineteen days later, the patient was reanesthetized for forequarter amputation plus radical chest wall resection, including ribs 3–8 and all associated soft tissues plus adjacent spinous processes. Postoperatively, the patient developed acute respiratory failure secondary to hypoventilation. The cat was mechanically ventilated for 12 h prior to being successfully weaned from the ventilator. However, the improvement was transient and mechanical ventilation was reinitiated 6 h later owing to respiratory fatigue. On the second day, the cat developed unexplained central nervous system signs and was euthanized.

Relevance and novel information

To our knowledge, this is the first case report to describe ventilatory failure secondary to radical chest wall resection in a cat. Hypoventilation with subsequent need for mechanical ventilation is a potential complication that should be considered during preoperative planning in patients requiring extensive chest wall resections.
Uncovering the low-profile #MeToo movement: Towards a discursive politics of empowerment on Chinese social media
Authors: Han Xiao
Published: July 2021

In China, a few posts related to #MeToo movement survived and remained online well after its peak and the state’s response in July 2018. This article proposes a theoretical framework that pays attention to discursive meaning-making and employs a broad notion of empowerment, referred to as ‘empowerment through discourse’, in order to offer a more nuanced understanding of the low-profile #MeToo movement in the Chinese context. This framework is used to analyse a corpus of uncensored #MeToo material, which appeared on Chinese social media. This article combines a discourse analysis of these posts and interviews with feminists from activist collectives to critically examine feminist empowerment by reflecting on survivor/victim narration and storytelling practices, digital media’s capacity to facilitate critical dialogue between witnesses and survivors/victims and activist collectives’ organising role in opening up a dialogic space for collective reading, listening and healing. These reflections lead to broader considerations on how notions of empowerment can spur collective action and structural change. In short, this article demonstrates the potential possibility of discursive change and reflects on this mode of feminist politics as a way to speak to empowerment in the Chinese context.
Object Control Skills Training for Children With Intellectual Disability: An Implementation Case Study
Authors: Capio Catherine M. , Eguia Kathlynne F.
Published: July 2021

Children with intellectual disability (ID) tend to have difficulty with mastering fundamental movement skills, associated with cognitive deficits that impair skill acquisition. In this case study, motor learning evidence was transformed into an object control skills training program for children with ID in a school context. An implementation framework was used for program design, pilot, and evaluation. Research evidence on error-reduced motor learning was combined with practitioners’ insights to inform the program design. Children with ID in the participant school were allocated to a training or control group for the pilot; object control skills proficiency was the measured outcome. The lead trainer was interviewed and their notes were reviewed for process evaluation. Significant improvements in participants’ object control skills proficiency were found following training. The process evaluation confirmed fidelity and identified implementation factors. The systematically designed application was found beneficial for children with ID. Implementation criteria were identified for future iterations of an error-reduced approach to training movement skills of children with ID.
Risk as an Approach to Regulatory Governance: An Evidence Synthesis and Research Agenda
Authors: van der Heijden Jeroen
Published: July 2021

Governments around the world have begun to develop and implement risk governance and risk-based regulation and are often inspired by the insights from risk studies in doing so. Following these developments, scholars have begun to map, explore, and interrogate risk governance models and strategies and risk-based regulatory approaches and instruments, and their performance. This article presents an evidence of academic literature on risk as an approach to regulatory governance. It follows the logic and applies tools of meta-research, a systematic and replicable process of synthesizing research findings across a body of original research. Following a staged approach, 135 peer-reviewed journal articles from an initial body of 1,125 articles were analyzed. The article presents the main findings from the evidence synthesis, presents the gaps in our knowledge, and suggests a future agenda for research on risk as an approach to regulatory governance. The article finds that despite ongoing conceptual and normative debates about the need for risk governance and risk-based regulation, we lack a good understanding of how it operates in practice. Future scholarship is urged to be critical of the potential gap between academic and policy rhetoric on risk-based regulatory governance and the application of this approach to regulatory governance on the ground.
CSR Initiatives and Practices: Empirical Evidence From Indian Metal and Mining Companies
Authors: Singal Ajay K.
Published: July 2021

This study investigates the corporate social responsibility (CSR) discourse on community and environment by Indian metal and mining (extractive) sector. Specifically, we examine the change in internal governance and external implementation mechanisms in response to affirmative CSR policy actions. Applying text network analysis technique on CSR related expenditures provided in the annual reports and CSR annexures (2014–2018), our study reveals that CSR discourse of extractive firms improved significantly and became more focused after the introduction of post-affirmative policy. CSR initiatives in the extractive sector are primarily focused toward local social development, with little emphasis on the environmental sustainability. Furthermore, companies have adopted two-tier governance structures for managing CSR. The top tier comprises board members who formulate the CSR programs, while the second tier has executives responsible for the implementation. Another tier of governance involving local domain experts is emerging. The three-tier implementation mechanisms give firms a tighter control on spending and enhance the effectiveness of initiatives. We present the results visually in the form of network graphs.
Lumbar Level Significantly Influences Postoperative Global Sagittal Balance Following Pedicle Subtraction Osteotomy
Authors: Zavras Athan G. , Sullivan T. Barrett , Dandu Navya , An Howard S. , DeWald Christopher J. , Colman Matthew W.
Published: July 2021

Study Design:

Retrospective cohort study.

Objectives:

The current evidence regarding how level of lumbar pedicle subtraction osteotomy (PSO) influences correction of sagittal alignment is limited. This study sought to investigate the relationship of lumbar level and segmental angular change (SAC) of PSO with the magnitude of global sagittal alignment correction.

Methods:

This study retrospectively evaluated 53 consecutive patients with adult spinal deformity who underwent lumbar PSO at a single institution. Radiographs were evaluated to quantify the effect of PSO on lumbar lordosis (LL), thoracic kyphosis (TK), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), T1-spinopelvic inclination (T1SPI), T1-pelvic alignment (TPA), and sagittal vertical axis (SVA).

Results:

Significant correlations were found between PSO SAC and the postoperative increase in LL ( r = 0.316, P = .021) and PT ( r = 0.352, P = .010), and a decrease in TPA ( r = −0.324, P = .018). PSO level significantly correlated with change in T1SPI ( r = −0.305, P = .026) and SVA ( r = −0.406, P = .002), with more caudal PSO corresponding to a greater correction in sagittal balance. On multivariate analysis, more caudal PSO level independently predicted a greater reduction in T1SPI (β = −3.138, P = .009) and SVA (β = −29.030, P = .001), while larger PSO SAC (β = −0.375, P = .045) and a greater number of fusion levels (β = −1.427, P = .036) predicted a greater reduction in TPA.

Conclusion:

This study identified a gain of approximately 3 degrees and 3 cm of correction for each level of PSO more caudal to L1. Additionally, a larger PSO SAC predicted greater improvement in TPA. While further investigation of these relationships is warranted, these findings may help guide preoperative PSO level selection.
Properties of Knee Joint Position Sense Tests for Anterior Cruciate Ligament Injury: A Systematic Review and Meta-analysis
Authors: Strong Andrew , Arumugam Ashokan , Tengman Eva , Röijezon Ulrik , Häger Charlotte K.
Published: July 2021

Background:

Knee proprioception is believed to be deficient after anterior cruciate ligament (ACL) injury. Tests of joint position sense (JPS) are commonly used to assess knee proprioception, but their psychometric properties (PMPs) are largely unknown.

Purpose:

To evaluate the PMPs (reliability, validity, and responsiveness) of existing knee JPS tests targeting individuals with ACL injury.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

PubMed, Allied and Complementary Medicine, CINAHL, SPORTDiscus, Web of Science, Scopus, CENTRAL, and ProQuest databases were searched to identify studies that assessed PMPs of knee JPS tests in individuals with ACL injury. The risk of bias for each included study was assessed and rated at the outcome level for each knee JPS test. Overall quality and levels of evidence for each PMP were rated according to established criteria. Meta-analyses with mean differences were conducted using random effects models when adequate data were available.

Results:

Included were 80 studies covering 119 versions of knee JPS tests. Meta-analyses indicated sufficient quality for known-groups and discriminative validity (ACL-injured knees vs knees of asymptomatic controls and contralateral noninjured knees, respectively), owing to significantly greater absolute errors for ACL-injured knees based on a strong level of evidence. A meta-analysis showed insufficient quality for responsiveness, which was attributed to a lack of significant change over time after diverse interventions with a moderate level of evidence. Statistical heterogeneity ( I 2 > 40%) was evident in the majority of meta-analyses. All remaining PMPs (reliability, measurement error, criterion validity, convergent validity, and other PMPs related to responsiveness) were assessed qualitatively, and they failed to achieve a sufficient quality rating. This was a result of either the study outcomes not agreeing with the statistical cutoff values/hypotheses or the level of evidence being rated as conflicting/unknown or based on only a single study.

Conclusion:

Knee JPS tests appear to have sufficient validity in differentiating ACL-injured knees from asymptomatic knees. Further evidence of high methodologic quality is required to ascertain the reliability, responsiveness, and other types of validity assessed here. We recommend investigations that compare the modifiable methodologic components of knee JPS tests on their PMPs to develop standardized evidence-based tests.
