A Gap in Culturally Responsive Classroom Management Coverage? A Critical Policy Analysis of States’ School Discipline Policies
Authors: Williams John A. , Mallant Cheryl , Svajda-Hardy Megan
Published: April 2022

A signature item that beleaguers most teachers is classroom management. Recognizing the futility of punitive classroom management within school discipline practices, Weinstein and colleagues forged culturally responsive classroom management (CRCM). While nearly 20 years of scholarship highlights the importance of teachers employing CRCM to reduce their reliance on punitive discipline approaches, which are disproportionally skewed against students of color, there exists a gap between educational research and educational policies concerning the use of CRCM in schools. We employed a critical policy analysis to determine the existence of CRCM in student code-of-conduct policies, across all 50 states. Our findings highlight an absence of CRCM in states’ policies, and limited support for the incorporation of CRCM in schools and school districts. Ultimately, an opportunity awaits stakeholders (teachers, school districts, education preparation programs, and policymakers) to reform educational policies and the tools teachers can employ to affirm and sustain students’ learning environments.

Published: April 2022

Today, the automotive industry faces its biggest challenge, which is keeping a constant evolution, accounting for the market needs in what comes to the enormous quantity of parts and systems that go hand in hand with the production of the vehicle, and at the same time, keep up with the quality requirements and deadlines. Throughout time, automation and robotics became the best way to achieve the goals required by the market. In the automotive industry, automation presents itself at a continuous evolution, constantly presenting new solutions, and the production and assembly lines increasingly resort to completely automated processes. This work is based on the needs of an automotive parts’ supplier. In which regards to the injection of plastic, the production is fluent and quick, and to take advantage of such production speed, it is desirable to execute the assembly steps immediately after the removal of the parts from the injection moulds. The proposed work consists of the design of a robotized cell with the goal of inserting metal clips in two different automotive parts after the injection process. The idea is to conceptualize and conceive a completely automated equipment, capable of executing this task using a six-axis robot. To secure the part for clip assembly, the equipment must be ready to ensure the positioning and locking of the part in all axes and, to lighten the robot’s job, it must also be capable of using a feeding system to load the robot’s tool. The results of this project were positive, the equipment was successfully concluded and delivered to the customer, meeting the construction requirements, and, most importantly, the cycle time.
Thermally and organomodified montmorillonite as effective regulators of the structure formation process in polypropylene/polystyrene blends
Authors: Budash Yurii , Rezanova Natalia , Plavan Viktoriia , Rezanova Viktoriia
Published: April 2022

The influence of the concentration of thermally and organomodified montmorillonite on the processes of structure formation in a blend of polypropylene/polystyrene (PP/PS) was studied. It is established that in nanofilled compositions, as well as in the original, is formed a microfibrillar structure, the dimensional characteristics of which depend on the content of the additive and the method of its modification. The investigated clays by content (0.2–2.0) wt. % by weight of polypropylene have a compatibilizing effect in the blend of PP/PS, which reduces the average diameter of microfibers by 1.6 times and increases the homogeneity of their distribution by diameter: statistical indicators decrease (standard deviation, variance, coefficient of variation). The modifying effect of thermally modified clay is higher—the improvement of the dimensional characteristics of PP microfibers is achieved at its minimum content in the blend (0.2 wt. %). The formation of anisotropic PP structures in the PS matrix and the relaxation of the accumulated stresses at the exit of the molding hole is the main factor that causes high values of the coefficient of swelling of the extrudates (4.0–7.7). The change in the microstructure of the extrudates of nanofilled systems during spinning depends on the composition of the blend and the method of modification of montmorillonite. The average diameters of microfibers decrease from 2.2 μm (in the original blend) to (1.3–2.0) μm (in three-component) depending on the content of additives. The ability to regulate the microstructure of incompatible polymer blends by introducing additives of thermally and organomodified montmorillonite will contribute to the creation of nanocomposites with controlled morphology, as well as new fine-fiber materials with improved filtering characteristics.
Quality as an Intermediate Goal of the Dutch Healthcare System: Presentation and Evaluation of the Quality of Cancer Care
Authors: Hrudey Ilona
Published: April 2022

Cancer care represents a challenge for the healthcare systems of OECD member states. This also applies to the Netherlands, as cancer is the leading cause of death. High quality of care is essential to effectively tackle the burden of disease caused by cancer. According to the WHO health systems framework, quality is an intermediate goal of health systems, alongside safety, access and coverage. This study aimed to assess the quality of cancer care in the Netherlands, especially in terms of effectiveness. To assess the quality of cancer care in the Netherlands, participation rates in screening and 5-year survival rates for breast, cervical and colorectal cancer were used. The Netherlands is interested in ensuring quality healthcare, and quality is one of the three main objectives of the healthcare system. The 5-year survival rates for breast, cervical and colorectal cancer were above the respective OECD averages in 2014, but some countries are better positioned. Participation in screening for cervical cancer was relatively low in the Netherlands in 2017, below the OECD average. It can be concluded that the Netherlands has high-quality, effective cancer care and is striving to continuously improve it. However, there is room for improvement , especially with regard to participation in cervical cancer screening, transparency about the quality of healthcare and regional differences in the quality of care.
Relationship Between Poor Sleep Quality and Injury Experience in Korea
Authors: Kim Sung-Kyung , Yong Sang Yeol
Published: April 2022

To develop preventive policies to reduce injuries, the responsible factors should be identified. In this study, causative factors were identified by analyzing data from the Korean Community Health Survey. Logistic regression was used to analyze the data of 192 480 individuals in the survey. Correlations were found between the injury experience and the following socioeconomic factors: age, sex, monthly income, smoking status, education, marital status, and neuropsychiatric factors: depressive symptoms, cognitive decline, and stress. The study subjects were divided into two groups based on sleep quality, as determined by Pittsburgh Sleep Quality Indices of ≤5 or >5. Logistic regression analysis adjusted for potential confounders revealed a correlation between sleep quality and injury experience. The odds ratio (OR) of poor sleep quality was associated with higher odds of injury (OR: 1.26), and it was also associated with higher odds of severe injury (OR: 1.23), even in the adjustment of socioeconomic factors only as well as in the adjustment of socioeconomic and neuropsychiatric factors. Poor sleep quality was associated with higher odds of several injury mechanisms of severe injury, such as slipping, poisoning, and falling into water.

Published: April 2022

Early intervention (EI) provision is critical for families who have children with developmental disabilities (DD), but existing evidence suggests accessing EI is not always straightforward. The purpose of this study was to provide a comprehensive description of access to various EI supports (e.g., professionals, services, interventions) for families of young children with suspected or diagnosed DD across the United Kingdom and to investigate perceived ease of access to support, unmet need for support, and barriers and facilitators of access to support. Overall, 673 parental caregivers of children aged 0 to 6 years with suspected or diagnosed DD (e.g., developmental delay, intellectual disability, autism) completed our survey anonymously. Across education, health, and social care, services accessed the most were pediatrics ( N = 569, 84.5%), speech and language ( N = 567, 84.2%), and general medical practice ( N = 530, 78.8%). However, only 18.9% ( N = 127) accessed packaged interventions. More than three-quarters ( N = 508, 75.5%) reported an unmet need for early support, indicating a mismatch between the availability and capacity of services and demand for support. Parents also reported common barriers (e.g., obstructive services and unhelpful professionals) and facilitators (e.g., supportive and competent professionals, enabling parent factors) of access. Implications for policy, practice, and research are discussed.

Published: April 2022

Many preschool agencies nationwide continue to experience closures and/or conversions to virtual or hybrid instruction due to the ongoing coronavirus disease 2019 (COVID-19) pandemic. Despite the importance of understanding young children’s learning and development during the COVID emergency, limited knowledge exists on adaptable practices for assessing young children during the pandemic. We assess the learning of 336 Head Start children across four states and three different time periods during the 2020 to 2021 school year, using adaptations of traditionally in-person assessments of early numeracy, early literacy, and executive functioning. In doing so, we distill early lessons for the field from the application of a novel, virtual assessment method with the early childhood population. This article describes the adaptations of assessment administration for virtual implementation and incorporation of feedback into continued virtual delivery of assessments. Applications and limitations in broader contexts are discussed.
Adalimumab-Adbm: The First Interchangeable Biosimilar for the Treatment of Inflammatory Diseases
Authors: Bhat Shubha , Patel Maitri , Duly Kristine , Choi David
Published: April 2022

Objective

The objective of the study was to review the pharmacologic and clinical profile of adalimumab-adbm (BI 695501), the first interchangeable biosimilar for treatment of inflammatory diseases.

Data Sources

A PubMed search was conducted from inception to December 2021 using the keywords BI 695501 and adalimumab-adbm. Information was also obtained from published abstracts and package inserts.

Study Selection and Data Extraction

Phase 1, 2 and 3 studies plus relevant literature on adalimumab-adbm pharmacologic and clinical profile were reviewed.

Data Synthesis:

Adalimumab-adbm approval was based on a series of phase 3 VOLTAIRE trials, which evaluated the biosimilar’s efficacy and safety in the treatment of moderate to severe Crohn’s disease, rheumatoid arthritis, and psoriasis. Interchangeability status was granted based on data from the VOLTAIRE-X trial. The VOLTAIRE and VOLTAIRE-X studies demonstrated comparable efficacy and safety between adalimumab-adbm and reference adalimumab. Common adverse events included infections and injection site reactions. Similar to reference adalimumab, adalimumab-adbm contains black box warnings related to serious infections and malignancy.

Relevance to Patient Care and Clinical Practice

Adalimumab-adbm is the first interchangeable biosimilar to be approved for inflammatory diseases and has the potential to improve patient access to treatment while decreasing medication-related costs. However, it will not be commercially available for patient use until 2023 and its adoption into clinical practice may face potential barriers seen with other biosimilars.

Conclusion

As an interchangeable biosimilar with comparable efficacy and safety to reference adalimumab, adalimumab-adbm is an important advance toward cost-effective management of inflammatory diseases.
Firm Performance During a Crisis: Effects of Adhocracy Culture, Incremental Product Innovation, and Firm Size
Authors: Noone Breffni M. , Lin Michael S. , Sharma Amit
Published: April 2022

The government-mandated closure of U.S. restaurants for in-restaurant dining during the early stages of the COVID-19 crisis cast a spotlight on operators’ ability to effectively innovate, and re-imagine their product offerings. In this context, this research draws on the resource-advantage theory of competitive advantage, proposing that (1) an adhocracy culture is a key internal resource that operators can leverage to drive rapid incremental product innovation under forced change, and (2) firm size is a contextual factor that moderates the degree of incremental product innovation-firm performance relationship. Findings from two empirical studies indicate that adhocracy culture positively and indirectly effects firm performance through degree of incremental product innovation, and that this effect is moderated by firm size. Larger firms yield superior performance effects due to access to a network of interconnected resources for rapid innovation diffusion in a crisis.
Arteriovenous fistula self-care behaviors in patients receiving hemodialysis treatment: Association with health literacy and self-care agency
Authors: Bulbul Elif , Yildiz Ayvaz Meryem , Yeni Tugba , Turen Sevda , Efil Sevda
Published: April 2022

Background:

Arteriovenous fistula-related self-care behaviors, self-care agency and health literacy are important for vascular access patency, which is vital in the continuation of hemodialysis treatment. The purpose of this study was to determine the arteriovenous fistula-related self-care behaviors of patients receiving chronic hemodialysis treatment and the relationship between these behaviors and their health literacy and self-care agency levels.

Methods:

In this descriptive correlational study, the data were collected from 216 chronic hemodialysis patients.

Results:

The rate of the patients who had good self-care behaviors levels was 83.96%. The sociodemographic variables that were significantly related to AVF-related self-care behaviors were education, employment status and age. It was found that the patients who had had AVF for a longer time had better self-care behaviors regarding their management of symptoms and findings ( p < 0.05). As the self-care agency of the patients ( r = 0.612, p < 0.001) and their health literacy ( r = 0.421, p < 0.001) increased, their AVF-related self-care behaviors also increased.

Conclusion:

Age, education status, health literacy and self-care agency were identified to affect AVF-related self-care behaviors.
Effect of kidney transplantation activity on arteriovenous fistula use in prevalent haemodialysis patients: A registry-based study
Authors: Roca-Tey Ramon , Comas Jordi , Tort Jaume
Published: April 2022

Background:

Kidney transplantation (KT) is considered to be the best kidney replacement therapy (KRT) option for most end-stage kidney disease (ESKD) patients. Arteriovenous fistula (AVF) is considered to be the best vascular access (VA) for most haemodialysis (HD) patients. In this study, we investigated the effect of KT activity on AVF use in prevalent HD patients. The probability of receiving a kidney graft (KTx) over time, depending on the first VA used to start the HD program, was also evaluated.

Methods:

Data from the Catalan Registry of prevalent patients on KRT by either KT or HD were examined over a 20-year period (1997–2017).

Results:

The percentage of prevalent ESKD patients with a functioning KTx increased from 40.5% in 1997 to 57.0% in 2017 and, conversely, the percentage of AVF utilisation in HD patients decreased from 86.0% to 63.2% during the same period (for both comparisons, p < 0.001). This inverse relationship was also demonstrated in other countries and regions worldwide by performing a simple linear regression analysis ( R2 = 0.4974, p = 0.002). The probability of prevalent patients dialysed through an AVF in Catalonia was independently associated with the percentage of functioning KTx among KRT population, after adjusting by age, gender, primary kidney disease, time on KRT, cardiovascular disease and type of HD Unit. Incident patients starting HD through an AVF had a significantly higher probability of receiving a KTx over time in comparison to patients who initiated HD through a catheter (hazard ratio 1.68 [95% confidence interval: 1.41–2.00], p < 0.001).

Conclusions

In addition to some demographical and clinical characteristics of patients and type of HD Unit, KT activity can be a determining factor in AVF use in prevalent HD patients. Starting an HD programme through an AVF is independently associated with a greater probability of receiving a KTx as compared to starting HD through a catheter.
Regionalism or Multilateralism: Evidence from India
Authors: Kathjoo Umar Nisar , Fazili Asif
Published: April 2022

With an impasse at Doha round of negotiations, many countries started to change their course of economic liberalization from generic policies of multilateralism to regional trade agreements (RTAs). In this scenario, India plausibly lacks the presence and will of concluding such agreements with some of its major trading partners while being sceptical about the existing ones. Using structural gravity, this study has quantified the impact of country-specific globalization levels and RTAs on international trade among India and its 32 major trading partners. Unlike a plethora of studies employing the gravity model on Indian trade policy issues, we have made use of many recent advancements in gravity modelling. Our methodology robust to the use of intra-national trade data, two alternative estimators, and multiple scenarios naturally addresses the endogeneity issues that are prominent with trade policy variables like RTAs. The empirical results reveal that RTAs have a comparatively strong impact in promoting trade among sample countries. However, country-specific globalization levels measured by the KOF globalization index have a very negligible impact on promoting trade among sample countries. Furthermore, we have obtained very slight asymmetries across the impact of country-specific globalization levels on exports versus imports of mid-income countries with high-income countries.

Acceptance of vulgarity in marketing: The moderating roles of product type and consumers’ political ideology
Authors: Verhoff Stephen David , Chan Eugene Y
Published: April 2022

One debate about theories of disgust surround whether the emotion is elicited by adaptationist or by cultural sensitivities. We examine this question by examining the disgust that profanity elicits. This research examines two moderators that predict consumers’ acceptance of vulgar language within advertising contexts. Specifically, we focus on product type (new vs old) and consumers’ political ideology (conservative vs liberal), proposing that conservatives (vs liberals) are less accepting of new (vs existing) products advertised using vulgar language. This is potentially because, we propose and find, conservative consumers are more sensitive to the disgust emotion, and new products advertised with vulgar language elicit more disgust. We conducted three experiments to test the hypotheses. Experiment 1 finds support for our overall hypothesis while Experiments 2 and 3 find evidence for the role of disgust via both mediation and moderation techniques. Our findings suggest that the disgust emotion is driven by cultural and not purely by evolutionary sensitivities. We are also the first authors, to our knowledge, to connect the disgust literature to vulgar language. Hence, our findings offer both practical and theoretical implications regarding the use of vulgar language in marketing.
“Pose”: Examining moments of “digital” dark sousveillance on TikTok
Authors: Peterson-Salahuddin Chelsea
Published: April 2022

Over the past year, many young creators who use the Chinese-owned social networking platform TikTok have claimed that its underlying algorithm surveils and suppresses the reach of content by Black, brown, fat, queer, and disabled creators. However, despite these algorithmic biases, these marginalized creators have continued to find new and ingenious ways to not only create but also successfully share anti-racist, anti-misogynistic, LGBTQIA+supportive, and body-positive content on the platform. Using this tension, this essay engages visual content analysis and critical technocultural discourse analysis to examine the innovative ways marginalized creators employ TikTok’s various medium and technological affordances to evade algorithmic surveillance and oppression. Building on Simone Browne’s concept of dark sousveillance, I theorize these practices as acts of digital dark sousveillance, defined within the essay as the use of digital tools to enact surveillance subversion, obfuscation, inversion while operating within systems of racializing surveillance.
Growing and Glowing: A Digital Media Campaign to Increase Access to Pregnancy-Related Health Information for Black Women During the COVID-19 Pandemic
Authors: Bonnevie Erika , Barth Chelsea , May Jamillah , Carey Toni , Knell Savannah B. , Wartella Ellen , Smyser Joe
Published: April 2022

Background

Low birthweight is a health issue disproportionately experienced by Black women. In Hillsborough County, Florida, Black women experience higher rates of low birthweight compared to the rest of Florida. This study examines the feasibility of a second attempt to use a digital low birthweight campaign to increase knowledge about low birthweight and pregnancy among Black women in Hillsborough.

Methods

Content for the Growing and Glowing campaign was delivered on social media through a web series with local prenatal care providers and educational images. Two cross-sectional surveys examined changes in pregnancy-related knowledge, attitudes, and behaviors among Black women in Hillsborough. Digital metrics showed campaign reach and engagement.

Results

Growing and Glowing attained 1,234 followers, 805,437 impressions, and a reach of 19,875. Web series videos were viewed almost 27,000 times, with 89% average viewer retention. The website attracted 2,634 unique page views. Evaluation surveys showed significant improvements in positive pregnancy-related intentions. Women aware of the campaign showed significantly higher awareness of the importance of prenatal care, and higher awareness of local resources.

Conclusion

Results from the second study of this campaign approach suggest that using a highly targeted digital intervention can be a well-received and potentially effective way to deliver pregnancy-related health information to Black women, even during a global pandemic. This approach has numerous benefits in reaching women who may fall outside traditional health marketing approaches.
Endovascular Thrombus Aspiration and Catheter-Directed Thrombolysis for Acute Thromboembolic Renal Artery Occlusion
Authors: Li Hai-Lei , Chan Yiu Che , Guo Zongjin , Zhou Ruming , Cheng Stephen W.
Published: April 2022

Purpose

We report a case of revascularization for an occluded renal artery using endovascular renal thrombus aspiration followed by catheter-directed thrombolysis.

Case Report

A 56-year-old man presented with sudden onset severe left-sided abdominal and loin pain for 6 hours. Urgent computed tomography (CT) angiogram showed occlusion of left renal artery. Emergency selective left renal angiogram and thrombus aspiration using a 5-French Cobra catheter was performed. Catheter-directed thrombolysis with urokinase was initiated after aspiration thrombectomy. Angiogram 24 hours after thrombolysis showed the left renal artery and its segmental branches were successfully revascularized. Patient was put on anticoagulation after operation and his renal function recovered well.

Conclusion

Percutaneous aspiration thrombectomy with conventional catheters combined with intra-arterial local fibrinolysis could be used to salvage the renal function in case of complete renal artery thromboembolic occlusion.
Novel Intraoperative CT-Guided Marking Using O-arm System in Video-Assisted Thoracoscopic Surgery: An Easy, Safe, Time-Saving, Practical Method
Authors: Yata Yumi , Hirai Yoshimitsu , Iguchi Hideto , Fusamoto Aya , Ohashi Takuya , Nishimura Yoshiharu
Published: April 2022

Objective: With the increased frequency of small lung tumor detection, there has been a similar increase in limited surgery, such as wedge resection. To identify such small lung tumors, we use a computed tomography (CT)–guided intraoperative marking method using the O-arm Surgical Imaging System. We retrospectively investigated its usefulness. Methods: Of 1,043 cases of thoracic surgery performed at our department between May 2017 and June 2021, O-arm System marking was used in 30 cases (2.9%), totaling 39 lesions. Tumor location was predicted preoperatively based on 3-dimensional CT and anatomic positioning. Visceral pleura near the tumor was marked with a metal clip, and the O-arm System was brought to the surgical site. CT was taken after the tumor side lung was fully re-expanded and clamped. After confirming the tumor and the clip locations, the clip was repositioned as necessary and marked in the same way. If the marking was successful, the clips were used as markers when performing lung resection. Results: Marking was successful in all cases. The average number of targets was 1.3, the average number of O-arm insertions was 1.3, and the average total number of marking clips was 2.6. In all cases, we checked the specimens, and if the tumor was palpable, the resection margin was also checked. No intraoperative or postoperative complications were observed in any patients. Conclusions: If the O-arm System is available, this technique is a noninvasive, simple, and useful method that could be widely used in clinical practice with a low dose of radiation.
Reoperation After Operative Treatment of Open Finger Fractures
Authors: Oflazoglu Kamilcan , Smits Lisanne J. H. , Rakhorst Hinne , Eberlin Kyle R. , Ritt Marco J. F. P. , Chen Neal C.
Published: April 2022

Background

Our primary aim was to develop a prediction model for return to the operating room (OR) after open finger fractures by studying the reoperation rate of open finger fractures based on patient demographics, injury mechanism, injury severity, and type of initial surgical fixation. The secondary aim was to study the predictors for secondary surgery due to nonunion, postoperative infection, and secondary amputation.

Methods

In the retrospective chart review, 1321 open finger fractures of 907 patients were included. Demographic-, injury-, and treatment-related factors were gathered from medical records.

Results

We found that open fractures involving the thumb had lower odds of undergoing secondary surgery. Crush injury, proximal phalangeal fracture, arterial injury, other injured fingers, and other injuries to the ipsilateral hand were associated with higher odds of undergoing secondary surgery. However, the associated factors we identified were not powerful enough to create a predictive model. Other injury to the ipsilateral hand, vein repair, and external fixator as initial treatment were associated with postoperative nonunion. Crush injury and proximal phalangeal fracture were associated with postoperative infection. No factors were associated with secondary amputation.

Conclusions

A quarter of open finger fractures will likely need more than one surgical procedure, especially in more severely injured fingers, due to crush or with vascular impairment. Furthermore, fractures involving the thumb have less reoperation, while fractures involving the proximal phalanx have poorest outcomes.
Patient outcomes after treatment of brain aneurysm in small diameter vessels with the silk vista baby flow diverter: A systematic review
Authors: Hanel Ricardo A , Cortez Gustavo M , Benalia Victor H C , Sheffels Erin , Sutphin Daniel J , Pederson John M , Pereira Vitor M
Published: April 2022

Background

The Silk Vista Baby (SVB, BALT) is a first-in-class flow-diverter device delivered using a 0.017” microcatheter, designed for the treatment of intracranial aneurysms, including those in small diameter vessels. This study reports a systematic literature review (SLR) to evaluate the safety and efficacy of using SVB to treat intracranial aneurysms in vessels less than 3.5 mm in diameter.

Methods

We performed a PRISMA-compliant SLR to evaluate the outcomes of SVB in the treatment of aneurysms in small intracranial vessels. Primary outcomes were occlusion status and major stroke, and secondary outcomes included all-cause mortality, procedure-related neurologic death, and post-operative aneurysm rupture. Data were expressed as descriptive statistics only.

Results

A total of four studies, including 163 patients with 173 intracranial aneurysms, were included. The most common aneurysm locations were the anterior cerebral artery (24.9% [43/173]), the middle cerebral artery (24.3% [42/173]), and the anterior communicating artery (23.1% [40/173]). Parent artery diameter ranged from 0.9 mm to 3.6 mm, and 29% were acutely or previously ruptured aneurysms. Overall, complete or near-complete occlusion was 72.1% on early-term follow-up. Mortality rate among the studies was 2.5%, with 3 instances adjudicated as neurologic deaths (1.8%). Major stroke was noted in 1.2% of cases, and branch occlusion or stent thrombus formation in 5.5%.

Conclusion

Our review suggests that SVB is a safe and effective treatment for intracranial aneurysms in small vessels. Further prospective and comparative studies with patient outcome data specific to aneurysm location are needed to confirm the safety and efficacy of SVB.
Tribological behavior of pits textured multi-rollers sliding-rolling tribo-pair under periodic varied load and dry wear
Authors: Long Risheng , Li Manhong , Jin Zhihao , Zhang Yimin , Han Hui
Published: April 2022

To reveal the influence of pit units on the friction and wear performance of multi-rollers-sliding-rolling tribo-pairs (MRSRTs), the tribological behavior of pits textured MRSRTs with 18 rollers under periodic varied load and dry wear were researched. The texture parameters include: diameter of pits (DAOP, 200, 250, and 300 μm), depth of pits (DPOP, 10, 20, and 30 μm). The wear losses and worn surfaces of samples were obtained. The influence mechanism of pits on the tribological performance of MRSRT was also discussed. The results show that: The average coefficients of friction (COFs) of pits textured MRSRTs are all lower than that of smooth one under periodic varied load and dry wear. Their mass losses are almost all higher than that of smooth MRSRT. The influence of DPOP on the tribological properties of textured MRSRTs is significant and continuous compared with that of DAOP. The depth-diameter ratio is an important factor for the wear losses. In this work, when the DAOP is 200 μm and the DPOP is 30 μm, that is, the depth-diameter ratio is 0.15, compared with the smooth sample, the mass loss of MRSRT is reduced by about 13%, and its average COF is reduced by 30.5%. This work can provide a valuable reference for the surface design and optimization of rolling element bearings.
Transcarotid artery revascularization in reverse for innominate artery stenosis
Authors: Mukherjee Dipankar , Kittner Janine
Published: April 2022

Stenotic lesions of the supra-aortic vessels have been reported in 2–6% of patients presenting with corresponding symptoms. In the past, these lesions have been treated with open surgical techniques. More recently, endovascular treatment approaches have been proposed for occlusive lesions in the innominate (IA) or common carotid (CCA) arteries. Retrograde stenting of IA and CCA lesions using flow reversal has been described in a retrospective case series; however, a modification of their technique is proposed. Case Presentation: The patient is a 68-year-old male with symptoms of right upper extremity claudication. CT angiogram revealed critical stenosis of the innominate artery and high-grade stenosis of the right subclavian artery. The patient consented to retrograde stenting of the innominate stenosis with neuroprotection using flow reversal or transcarotid revascularization (TCAR) in reverse. Surgical cut-down was performed of the carotid bifurcation, and a U-stitch was placed on the anterior wall of the distal common carotid artery. Flow reversal was achieved by connecting the arterial sheath to the venous sheath. The innominate lesion was crossed, primarily stented with a VBX stent, and post-dilated with a non-compliant balloon. Just prior to crossing the lesion and primary stent placement, the vessel loop around the common carotid and internal carotid arteries were pulled up to ensure neuroprotection while the stent was expanded. This was continued for two minutes before restoring antegrade flow first in the external carotid and then in the internal carotid artery. There were no adverse events. At one month follow-up, the patient reported no right arm claudication symptoms. TCAR for the proximal lesion as described in other case series may not adequately attain flow based neuroprotection. Under that circumstance, the arterial sheath is acting as a conduit to deliver the stent. Risk of embolization to the brain may not be mitigated when the proximal lesion is stented and antegrade flow restored.

Published: April 2022

Background:

Glomerulonephritis (GN) is a leading cause of kidney failure and accounts for 20% of incident cases of end-stage kidney disease (ESKD) in Canada annually. Reversal of kidney injury and prevention of progression to kidney failure is possible; however, limited knowledge of underlying disease mechanisms and lack of noninvasive biomarkers and therapeutic targets are major barriers to successful therapeutic intervention. Multicenter approaches that link longitudinal clinical and outcomes data with serial biologic specimen collection would help bridge this gap.

Objective:

To establish a national, patient-centered, multidimensional web-based clinical database and federated virtual biobank to conduct human-based molecular and clinical research in GN in Canada.

Design:

Multicenter, prospective observational registry, starting in 2019.

Setting:

Nine participating Canadian tertiary care centers.

Patients:

Adult patients with a histopathologic pattern of injury consistent with IgA nephropathy, focal and segmental glomerulosclerosis, minimal change disease, membranous nephropathy, C3 glomerulopathy, and membranoproliferative GN recruited within 24 months of biopsy.

Measurements:

Initial visits include detailed clinical, histopathological, and laboratory data collection, blood, urine, and tonsil swab biospecimen collection, and a self-administered quality of life questionnaire. Follow-up clinical and laboratory data collection, biospecimen collection, and questionnaires are obtained every 6 months thereafter.

Methods:

Patients receive care as defined by their physician, with study visits scheduled every 6 months. Patients are followed until death, dialysis, transplantation, or withdrawal from the study. Key outcomes include a composite of ESKD or a 40% decline in estimated glomerular filtration rate (eGFR) at 2 years, rate of kidney function decline, and remission of proteinuria. Clinical and molecular phenotypical data will be analyzed by GN subtype to identify disease predictors and discover therapeutic targets.

Limitations:

Given the relative rarity of individual glomerular diseases, one of the major challenges is patient recruitment. Initial registry studies may be underpowered to detect small differences in clinically meaningful outcomes such as ESKD or death due to small sample sizes and short duration of follow-up in the initial 2-year phase of the study.

Conclusions:

The Canadian Glomerulonephritis Registry (CGNR) supports national collaborative efforts to study glomerular disease patients and their outcomes.

The Use of Drama Pedagogy in Teaching Morality in a Chinese Primary School
Authors: Feng (冯梦雨) Mengyu
Published: April 2022

Purpose

This paper aims to explore the potential of the drama pedagogy that may contribute to primary children's moral growth in the Chinese educational context. It argues that drama may offer an ensemble-based, dialogic, and narrative pedagogy for teaching morality to complement the didactic traditional model.

Design/Approach/Methods

The methodological approach is that of case study research, using different methods to assess the effects and effectiveness of the author's teaching. The fieldwork was undertaken in a public primary school in Beijing, in which the drama workshop The Boat was taught to 16 children on a voluntary basis.

Findings

The study demonstrates that drama can be seen to some extent to assist pupils in aspects of their empathetic attitudes, dialogic thinking abilities, and autonomous thinking capacities.

Originality/Value

The author hopes the study might stimulate more and deeper research in similar contexts and that this may further extend the understanding of Chinese teachers of this resourceful new pedagogy.

Authors: Chen Jennifer J.
Published: April 2022

Highlights

This commentary centers on one of the insightful articles in this Special Issue: “Curriculum Hybridization and Cultural Glocalization: A Scoping Review of International Research on Early Childhood Curriculum in China and Singapore,” authored by Yang and Li (2022) . The commented article provides insights and directions regarding early childhood curriculum policy and practice in China and Singapore. Aligning with Yang and Li’s (2022) findings, this commentary further paints a new three-component framework (the foreground, the background, and the middle ground) for understanding and harmonizing the global–local dissonance in the early childhood curriculum landscape. Leveraging both hindsight and foresight, this commentary also provides insights for policy and practice to advance a harmonious early childhood curriculum landscape in China and Singapore as well as in other societies confronted with similar predicaments.

Published: April 2022

The advent of the era of big data is bound to promote the development of databases. How to bring clinicians’ focus back to clinical practice and enhance the clinical capabilities of general physicians at the primary level is a question that every member of the academic publishing profession needs to consider. If data and knowledge can be shared openly, research and medical management will develop at an accelerated pace. Given the global consensus on open science, the co-construction and sharing of a Chinese medical case repository will surely improve the practical capability of clinicians.
Percutaneous Posterior Cervical Pedicle Instrumentation (C1 to C7) With Navigation Guidance: Early Series of 27 Cases
Authors: Coric Domagoj , Rossi Vincent
Published: April 2022

Study Design:

This is a technique paper describing minimally invasive, navigated, percutaneous pedicle screw fixation of the cervical spine. In addition, we include a retrospective feasibility analysis of our initial experience with 27 patients undergoing this procedure.

Objective:

The purpose of this study is to describe the technique of MIS navigated percutaneous cervical pedicle screw instrumentation and to report our initial experience.

Methods:

This is a retrospective review of 27 patients undergoing MIS navigated percutaneous posterior cervical pedicle screw fixation at 2 institutions. We describe the technique and report the radiographic outcomes and all intraoperative and postoperative complications.

Results:

A total of 27 patients underwent MIS navigated percutaneous pedicle screw fixation. Indications included odontoid fracture, subaxial fracture dislocations and burst fracture, pathological fracture, and degenerative spondylosis. There were no nerve root or vascular injuries. There were no spinal cord injuries. Two screws required repositioning intraoperatively, and 1 patient required reoperation for symptomatic malpositioned screw.

Conclusions:

MIS navigated percutaneous posterior pedicle screw fixation can be performed safely. These constructs are biomechanically superior with neurovascular complication rates comparable to traditional lateral mass screw technique. While the current indications for this technique are relatively limited, the evolution of MIS cervical decompression techniques as well as navigation and robotics will provide an expanded role for percutaneous cervical pedicle screw instrumentation.
Comparative Analysis of Optoelectronic Accuracy in the Laboratory Setting Versus Clinical Operative Environment: A Systematic Review
Authors: Cunningham Bryan W. , Brooks Daina M.
Published: April 2022

Study Design:

Systematic review.

Objectives:

The optoelectronic camera source and data interpolation process serve as the foundation for navigational integrity in robotic-assisted surgical platforms. The current systematic review serves to provide a basis for the numerical disparity observed when comparing the intrinsic accuracy of optoelectronic cameras versus accuracy in the laboratory setting and clinical operative environments.

Methods:

Review of the PubMed and Cochrane Library research databases was performed. The exhaustive literature compilation obtained was then vetted to reduce redundancies and categorized into topics of intrinsic accuracy, registration accuracy, musculoskeletal kinematic platforms, and clinical operative platforms.

Results:

A total of 465 references were vetted and 137 comprise the basis for the current analysis. Regardless of application, the common denominators affecting overall optoelectronic accuracy are intrinsic accuracy, registration accuracy, and application accuracy. Intrinsic accuracy equaled or was less than 0.1 mm translation and 0.1 degrees rotation per fiducial. Controlled laboratory platforms reported 0.1 to 0.5 mm translation and 0.1 to 1.0 degrees rotation per array. Accuracy in robotic-assisted spinal surgery reported 1.5 to 6.0 mm translation and 1.5 to 5.0 degrees rotation when comparing planned to final implant position.

Conclusions:

Navigational integrity and maintenance of fidelity of optoelectronic data is the cornerstone of robotic-assisted spinal surgery. Transitioning from controlled laboratory to clinical operative environments requires an increased number of steps in the optoelectronic kinematic chain and error potential. Diligence in planning, fiducial positioning, system registration and intra-operative workflow have the potential to improve accuracy and decrease disparity between planned and final implant position.
Is it Safe to Save Levels and Choose the Lowest Instrumented Vertebra as Touched Vertebra While Selectively Fusing Lenke 1/2 Curves? A Proportional Meta-Analysis of Existing Evidence

Published: April 2022

Study design

Meta-analysis.

Objective

To compare the clinical and radiological outcomes in patients with Adolescent Idiopathic scoliosis (AIS) treated by selective thoracic fusion (STF) with lowest instrumented vertebra (LIV) at touched vertebra (TV) vs stable vertebra (SV).

Methods

The databases PubMed, Embase and Google Scholar were searched until November 2020.Studies which had Lenke type 1 curves and Lenke type 2 curves in adolescent population treated by STF and which reported pre- and post-operative curve characteristics including correction percentage and complications were included. Studies which did not report the LIV selection, curve correction percentages and whose full text could not be acquired were excluded.

Results

Eight studies were included for analysis of which seven were found to be retrospective studies (level III evidence) and one was prospective study (level II evidence) each. Overall proportional meta-analysis found no significant difference in correction rate, total srs-22 scores, and complication rates.

Conclusion

The evaluation of SV group and TV group as LIV for selective thoracic fusions in AIS reveals a comparable outcome in terms of curve correction, patient satisfaction scores and complication rates. The TV can be chosen safely as the LIV especially in type A and B Lenke 1&2 curves, as it saves more motion segments when compared to SV.
Do Female Board Members Influence Corporate Social Responsibility Performance?
Authors: Oino Isaiah , Liu Jonathan
Published: April 2022

Caring for the environment has become everyone’s responsibility because of our significant negative impact. Considering this, companies are spending a substantial amount on corporate social responsibility (CSR) activities not only as part of corporate citizenship but also to enhance corporate image. Using a fixed-effect model on 2,260 companies’ annual data from 2012 to 2017, we analyze whether female board members influence CSR performance. The results indicate that the proportion of female board directors (PFBD) in Chinese firms is relatively small compared with the male. In other words, the boards members are predominantly male.

The fixed effects model indicates that both the number and proportion of female directors are significant in influencing CSR performance. Surprisingly, we note that the average age of female board directors has a significant and negative impact on CSR performance. The results also indicate that the education level of the female director does play a significant role in CSR performance. This demonstrates that firms need to recruit educated board directors and with a right mix of age.
