A Unique Presentation of Multicentric Myofibromatosis in the Masseter Muscle of a Pediatric Patient
Authors: Padilla Elena P. , Voelz Katie , Kille Tony
Published: September 2022

A 12-year-old female with a history of multicentric infantile myofibromatosis (IM) presented with a tender, enlarging cheek mass and trismus. Imaging identified an intramasseteric tumor. Given the unknown etiology of the tumor and her bothersome symptoms, the mass was excised using a transoral approach with concurrent facial nerve monitoring. Her pathology report confirmed the diagnosis of a myofibromatosis lesion embedded within the masseter muscle. While IM can often present with lesions in the head and neck region, the intramasseteric location is rare and presents unique considerations for surgical approach. Myofibromatosis lesions typically occur before two years of age, although there are some rare documented cases of multicentric myofibromatosis lesions presenting at older ages. Furthermore, this patient’s family history of similar lesions suggests a familial variant, which may have implications for disease behavior and need for further work-up, monitoring, and management. Overall, this was an unusual presentation of IM given the patient's age, prevalent family history, and the location of the mass. This case report adds to the literature and discusses the clinical differential of a pediatric cheek mass, the surgical considerations for an intramasseteric tumor, and the natural history of infantile myofibromatosis.

Published: September 2022

The aim of this study is to identify the strategic indicators Internet of Things (IoT) application in libraries and to present a conceptual model. The research was performed qualitatively and the data method of the foundation. Data were collected through documentary methods and interviews with a statistical sample of 13 professors of information science and the snowball sampling method. Interview data were analysed in three steps of open, axial and selective coding. Validity assessment was determined by the responsive method and reliability of two coding tests. After analysing the findings, 35 main codes of subcategories and concepts were discovered. The main categories were divided into eight categories: control and supervision, providing advanced services, accessibility, intelligence, maintaining security, new thinking and development, information literacy and method of use and satisfaction, and based on this, a paradigmatic and theoretical model was presented. In the theoretical model of the main phenomenon, the strategic indicators are the use of IoT in libraries, and the classes and the main phenomenon are related to the main class of application strategies. Strategic indicators of IoT application are leading in the growth and development of libraries. These indicators are important in the IoT use in libraries and their development. The eight categories identified in the conceptual model were considered significant by the interviewees. Thus, the indicators discovered are effective and necessary in the success of libraries that use the IoT.
Aesthetic Subjectification Through Ambivalent Play: Exploring a Ludic Theory of Popular Propaganda
Authors: Zou Sheng
Published: September 2022

Propaganda research was central to the coalescence of communication studies into a modern social science field in the early twentieth century. Positivist and behaviorist in its orientation, traditional propaganda research centers on questions of message and effect, brushing aside the culturally rich forms that propaganda assumes as well as the myriad ways in which subjects experience these forms on an aesthetic and sensorial level. This article endeavors to complement the message-and-effect-centric orientation by proposing a (re)turn toward the aesthetic dimension of propaganda, with a particular emphasis upon the nexus between propaganda and the concept of play. Drawing on observations from modern China, I venture a ludic theory of popular propaganda that captures the affective, non-discursive, and post-ideological dimensions of propaganda artifacts as well as subjects' aesthetic engagement with them. My intent in this article is to diversify the perspectives, approaches, and possibilities of propaganda research within the field of communication and media studies.

Published: September 2022

Background

Lung sleeve resection is indicated for centrally located lung tumors, especially for patients who cannot tolerate pneumonectomy. With video-assisted thoracoscopic surgery (VATS) being increasingly implemented for a wide variety of thoracic pathologies, this study aims to compare the intraoperative, postoperative, and long-term outcomes of VATS and open bronchial sleeve lobectomy for non-small cell lung cancer (NSCLC).

Methods

The MEDLINE (via PubMed), Cochrane Library, and Scopus databases were searched. Original clinical studies, comparing VATS and open sleeve lobectomy for NSCLC were included. Evidence was synthesized as odds ratios for categorical and weighted mean difference (WMD) for continuous variables.

Results

Our analysis included six studies with non-overlapping populations reporting on 655 patients undergoing bronchial sleeve lobectomy for NSCLC (229 VATS and 426 open). VATS sleeve lobectomy was associated with significantly longer operative time ((WMD): 45.85 min, 95% confidence interval (CI): 12.06 to 79.65, p  =  0.01) but less intraoperative blood loss ((WMD): −34.57 mL, 95%CI: −58.35 to −10.78, p < 0.001). No significant difference was found between VATS and open bronchial sleeve lobectomy in margin-negative resection rate, number of lymph nodes resected, postoperative outcomes (drainage duration, length of hospital stay, 30-day mortality), postoperative complications (pneumonia, bronchopleural fistula/empyema, prolonged air leakage, chylothorax, pulmonary embolism, and arrhythmia), and long-term outcomes (overall survival, recurrence-free survival).

Conclusions

The limitation of our study arises mainly due to the heterogeneity of the included studies. Nevertheless, VATS bronchial sleeve lung resection constitutes a feasible and safe alternative to the open sleeve lung resection surgery for the management of centrally located lung tumors.
Britain and the repression of Black Power in the 1960s and ‘70s
Authors: Gowland Ben
Published: September 2022

This article details the extensive security regimes deployed against Black Power in the Caribbean that were operated by regional governments and the (neo)colonial British state. These regimes of securitisation targeted radical Black political groups and actors whose Black Power ideology placed them in an antagonistic relation to independent West Indian states and Britain. The author argues that the British state’s involvement in the suppression of Black Power in the Caribbean is inseparable from the domestic repression of the British Black Power movement. But also, shared opposition to British (neo)imperialism and the personal ties of West Indian migrants to Britain connected Black Power resistance on both sides of the Atlantic. By drawing on British Foreign & Commonwealth Office, Ministry of Defence and Cabinet Office files, as well as political newspapers and publications produced at the time, the author traces the British state’s involvement in the transnational repression of Black Power in the late 1960s and early 1970s.
Considering a Need for Dementia-Specific, Family-Centered Patient Navigation in Canada
Authors: Kokorelias Kristina M. , Markoulakis Roula , Hitzig Sander L.
Published: September 2022

Patient navigation has been proposed as a novel family-centered, integrated care model to address the care needs of persons living with dementia and their family caregivers by helping them navigate the complex range of dementia services offered in hospital and community settings. A key informant qualitative descriptive study explored the perspectives of 48 healthcare professionals to explore the need for dementia-specific patient navigation. Data were analyzed thematically. We identified one overarching theme: “Variability in the Need for Illness-Specific Patient Navigation” and five themes that highlight considerations when providing navigation to individuals with dementia: (1) Taking Part in Ongoing Training, (2) Addressing Stigma, (3) Focusing on Quality of Life, (4) Defining Home, and (5) A Continuous Process of Support. These themes provide preliminary insights into the conceptual differences about the need for illness-specific patient navigation and the areas within patient navigation where healthcare professionals are encouraged to find consensus.

Published: September 2022

Virucidal properties of N-chlorosulfonamides immobilized on fibrous styrene-divinylbenzene copolymers have been studied. Corresponding materials with different functional group structures and chlorine content have been synthesized on FIBAN polymer carriers in the form of staple fibers and non-woven fabrics. The study has been conducted in general accordance with EN 14476 standard on poliovirus type-1 and adenovirus type-5. It has been found that all tested samples exhibit pronounced virucidal activity: regardless of the carrier polymer form, sodium N-chlorosulfonamides inactivated both viruses in less than 30 s, and N,N-dichlorosulfonamides—in 30–60 s. The main mechanism of action of these materials, obviously, consists in the emission of active chlorine from the functional group into the treated medium under the action of the amino groups of virus fragments and cell culture. Considering the previously described antimicrobial and reparative properties of such materials, as well as their satisfactory physical and mechanical properties, the synthesized polymers are promising for the creation of medical devices with increased resistance to microbial contamination, such as protective masks, filter elements, long-acting wound dressings, and others.
Nonconsensual Distribution of Intimate Images: Exploring the Role of Legal Attitudes in Victimization and Perpetration
Authors: Said Iman , McNealey Rachel L.
Published: September 2022

In the last 10 years, following widespread outcry among legal scholars and activists, 48 states passed legislation explicitly criminalizing the nonconsensual distribution of intimate images (NCDII) or what is colloquially known as “revenge porn.” This increased authority granted to criminal justice agencies, coupled with greater media attention to NCDII incidents, may have influenced patterns of victimization and perpetration. Using a survey recently distributed to a sample of young adults ( N = 713), we find that NCDII perpetration is strongly related to previous victimization, risky online behaviors, and receipt of unsolicited images. Perceptions of police efficacy in addressing NCDII issues is the strongest predictor of attitudes toward both reporting victimization and the belief that perpetrators will experience some punitive consequence. We also conducted an experiment using vignettes with gender varying victim-offender dyads to explore how gender bias influences attitudes toward punishment for NCDII perpetrators as well as perceptions of “revenge porn” in incidents involving same-sex and mixed-sex couples; we find that respondents are less likely to attribute “revenge porn” or to suggest punitive responses when the perpetrator is female regardless of the gender of the victim. Importantly, we find initial evidence of a new typology of NCDII perpetrator that counters existing research on victim–perpetrator gender dyads: women who nonconsensually disseminate unsolicited intimate images sent by men. Collectively, our findings challenge the efficacy of existing criminal statutes, identify new challenges in effectively legislating against NCDII, and contribute to the body of work on gender-based violence, perceptions of police efficacy, and punitive attitudes.
A customer-oriented method to support multi-task green scheduling with diverse time-of-use prices in Cloud Manufacturing
Authors: Tong Huagang , Zhu Jianjun
Published: September 2022

Green manufacturing has become a hot topic globally, and Cloud Manufacturing (CMfg) provides a novel approach to support green manufacturing through manufacturing services (MS) composition. In this study, we design a customer-oriented method for supporting multi-task green scheduling in CMfg. First, we aim to minimize the total energy consumption during scheduling. Second, because CMfg is a type of customer-oriented manufacturing, the just-in-time objective is used to meet the customers on-time requirements. Subsequently, we study the different time-of-use prices of MS in CMfg. The price of utilizing MS is related not only to cost but also to the supply-demand relationship, which results in diverse time-of-use prices for MS. After establishing the scheduling model, a hybrid artificial bee colony algorithm is designed to solve the scheduling model. For the algorithm, we design a guiding mechanism to enhance the global search ability and an adaptive variable neighborhood search for improving the local search ability. To verify the performance of our algorithm, we compared it with similar algorithms, and the results indicate the high-level performance of our work.

Published: September 2022

The response of many governments to the COVID-19 pandemic has involved measures to control within- and between-household transmission, providing motivation to improve understanding of the absolute and relative risks in these contexts. Here, we perform exploratory, residual-based, and transmission-dynamic household analysis of the Office for National Statistics COVID-19 Infection Survey data from 26 April 2020 to 15 July 2021 in England. This provides evidence for: (i) temporally varying rates of introduction of infection into households broadly following the trajectory of the overall epidemic and vaccination programme; (ii) susceptible-Infectious transmission probabilities of within-household transmission in the 15–35% range; (iii) the emergence of the Alpha and Delta variants, with the former being around 50% more infectious than wildtype and 35% less infectious than Delta within households; (iv) significantly (in the range of 25–300%) more risk of bringing infection into the household for workers in patient-facing roles pre-vaccine; (v) increased risk for secondary school-age children of bringing the infection into the household when schools are open; (vi) increased risk for primary school-age children of bringing the infection into the household when schools were open since the emergence of new variants.
The social production of property
Authors: Willer David , Emanuelson Pamela
Published: September 2022

This paper investigates two forms of property as a social phenomenon and finds the Property Right Paradigm of economics to be wrongly conceived. Introducing new formulations for property reveals that private and communal property are frequently found together. When they are, as the scope of one increases the scope of the other shrinks. We examine how property rights are embedded in social exchange experiments. Calling on game theory, we find that communal property relations and private property relations contain exactly the same social dilemma. Furthermore, absent enforced rights, no property exists. Property comes to exist through socially producing its rights and we show that production must be coercive. We link our new theory of property to Robѐ’s analysis of property and power in contemporary society.
Characteristics of complete circumferential guided wave in a piezoelectric semiconductor cylindrical shell
Authors: Chen Tao , Zhang Xiaoming , Zhou Hongmei , Yu Jiangong
Published: September 2022

In this paper, the characteristics of circumferential Lamb-like wave in a cylindrical shell of N-type piezoelectric semiconductor are investigated by employing the analytic Legendre orthogonal polynomial method (ALOPM). Based on the linear phenomenological theory, the governing differential equations are derived for different electrical boundary conditions, and transformed into a matrix eigenvalues problem via using the ALOPM. The dispersion solutions for a piezoelectric semiconductor cylindrical shell with big radius-thickness ratio obtained from the ALOPM are verified by comparing with the results from the global matrix method (GMM). Three-dimensional spectrum is plotted for a better observation. The spectrum of piezoelectric semiconductor is symmetrically distributed about the frequency axis, which is different from the piezoelectric dielectric material. The effects of different electrical boundary conditions, steady-state carrier density and radius-thickness ratio on phase velocity dispersion curves are illustrated. The amplitude distributions of displacement, electric potential and perturbation of the carrier density are studied. The effects of steady-state carrier density on the stress distribution are also illustrated. Non-propagating wave modes with low attenuation and high phase velocity value are found. The corresponding results presented in this work can be used to optimize the design of piezoelectric semiconductor acoustic wave devices.
Safe Among the Unsafe: Psychological Safety Climate Strength Matters for Team Performance
Authors: Fyhn Bård , Bang Henning , Egeland Therese , Schei Vidar
Published: September 2022

Team psychological safety, as a shared perception, is persistently found to be important for team performance. However, team members may not necessarily agree on the level of safety within the team. What happens when team members have dispersed perceptions of team psychological safety? Through a survey-based study involving 1,149 members of 160 management teams, we found that, not only is the level of team psychological safety positively related to team performance, but also that sharedness among team members (team psychological safety climate strength) moderates this relationship. The more team members agree on the level of team psychological safety, the stronger the effect of team psychological safety on team performance. Further, having at least one member who perceives the team as psychologically safe may lift team performance in a team of low psychological safety. We discuss theoretical and practical implications of looking beyond average levels of team psychological safety for building high-performing teams.

Young children with visual impairment and their families often require specialized assistance through early intervention to develop adaptive routines, cues, and environmental settings during mealtimes and other daily tasks. There is little empirical data in the area of mealtime routines available to support families of young children with visual impairment, and the need for research-based interventions is great. The purpose of this initial needs assessment survey was to gather information as little is already known about what teachers of students with visual impairment trained in early intervention (TSVI-EIs) and other early interventionists who work with infants and toddlers with visual impairment already know about the development of independent mealtime skills. The results of this survey indicate that early intervention professionals would like additional opportunities to learn about mealtime routine strategies for young children with visual impairment, confirm their current experiences and knowledge, and identify additional training and resources.
State Policy and Funding in Gifted Education
Authors: Hafenstein Norma L. , Boley Vicki , Lin Joi
Published: September 2022

Policy and funding influence equitable education for students who are gifted. The concept of equity is examined through variations in policy and in funding at the state, district, and local levels. Challenges and barriers to equity in policy and funding include policy structures, where policy provides guidance without accountability measures, or where policy does include systemic evaluation for improvement. Examples have been drawn from four different states in different areas of the United States and multiple examples from various districts are presented. State level mandates for identification of and service to gifted learners are presented, including those following the Exceptional Children’s Education Act and those not. Variations in definitions of gifted are articulated. District level policies, demonstrating local control, illustrate ranges of service and guidance. Examples of the broad range of funding available for gifted programming are articulated and include base funding as well as formulaic metrics. Adequate resources for equitable gifted education are explored by considering expenditures and allocations of funding, frequently dependent on locale, school size, and economic resources. A call for action suggests practices to improve equity in gifted education include building and implementing strong advocacy skills, pursuing fiscal support for services for gifted learners, and committing to a professional developed workforce through formal and informal professional learning for educators and policymakers. Educator attitudes and beliefs and public perceptions that may perpetuate myths are examined in relation to equitable services for gifted students.
Policy Considerations for Twice-Exceptional Students
Authors: Foley-Nicpon Megan , Teriba Akorede
Published: September 2022

Policies for talented students with disabilities, or twice-exceptional students, exist in very few states across the country. Historically, families of twice-exceptional students have found most of their support though implementation of Individualized Education Plans (IEPs) or 504 Accommodation plans. Yet, there is no federal mandate for gifted education service provision; consequently, these students’ coexisting high abilities often are overlooked. We recommend states modify their gifted and talented policies to address specifically twice-exceptional best practices in identification, such as using universal screening methods tied to curriculum interventions, and intervention, such as creating Gifted Individual Education Plans in conjunction with IEPs. These methods outline not only service provision for one’s disability but also specify methods for developing talent among twice-exceptional youth.

Using Bronfenbrenner’s systems approach, the authors examine events from 1999 to 2022 and how they may have influenced this generation of students. The authors close with ways of dealing with these changes by increasing an ethic of care for one another, dealing with the changes in our times with innovation and creative solutions, and focusing on ways to create a secure world for children that puts care for their positive well-being first.
Back to the (invisible) Académie? The organization of poetry as a “pure” art form
Authors: Dubois Sébastien
Published: September 2022

Using the case of French contemporary poetry, this article investigates the organization of “pure” art forms. These are highly legitimate art forms which, instead of being profit-oriented, comprise actors who strive primarily for esthetic recognition. The organizational life of such arts is based on a new academy system which is in some regards comparable to that of the 17th century—leading me to call the current system a “return to the academy.” I define an academy system as an assemblage of artistic institutions coupled with public funding for artists and artistic organizations. This two-pronged system organizes the arts along four dimensions: strategic, administrative, ideological, and professional. Its strategic mission is to support artistic creation, spread cultural democracy, and guarantee the construction and transmission of literary heritage. Paradoxically, the State cannot make these choices directly, firstly because of the widely accepted autonomy of art, and secondly because, in a democracy, the State can no longer select artists according to an explicit ideology. The academy is thereby “invisible.” Second paradox, its organization has led to the marketization of pure arts, and the transformation of artists into independent workers providing goods and services. Finally, I discuss how this system fits a new consumerist definition of culture, based on “traces” that have to be recorded and managed as heritage. These findings question the typical narrative that the arts were emancipated from the patronage system thanks to the market, as this does not apply to most artists.
Research on parameter optimization based on multi-body dynamics model of monorail vehicle aiming at reducing running wheel wear
Authors: Wen Xiaoxia , Huang Linkui , Du Zixue , Chen Liang , Yang Zhen
Published: September 2022

A nonlinear dynamic model of monorail vehicle and a finite element model of “running wheel-rail beam” system is established respectively, which is integrated into the Modefrontier platform. The total friction work and friction work deviation value are proposed as indicators for evaluating the wear and partial wear of the running wheels. Taking the total friction work and friction work deviation as the goals, the stability and curve passing performance of the monorail vehicle as constraints, and the structural parameters and dynamic parameters of the monorail vehicle as the optimization variables, an optimization model of partial wear of running wheel was established. The structural parameters and dynamic parameters of monorail vehicle are optimized through improved genetic algorithm. The analysis results show that the two indicators of the total friction work and friction work deviation value of the running wheels both decreased. Among them, the total friction work of the front right and rear right running wheel with severe partial wear was reduced by 20% and 21.2% respectively, the friction work deviation value was reduced by 19.30% and 27.2% respectively. The partial wear of the running wheel is improved significantly, and the purpose of reducing the partial wear of the running wheel is achieved.
Contextual in situ help for visual data interfaces

Published: September 2022

As the complexity of data analysis increases, even well-designed data interfaces must guide experts in transforming their theoretical knowledge into actual features supported by the tool. This challenge is even greater for casual users who are increasingly turning to data analysis to solve everyday problems. To address this challenge, we propose data-driven, contextual, in situ help features that can be implemented in visual data interfaces. We introduce five modes of help-seeking: (1) contextual help on selected interface elements, (2) topic listing, (3) overview, (4) guided tour, and (5) notifications. The difference between our work and general user interface help systems is that data visualization provide a unique environment for embedding context-dependent data inside on-screen messaging. We demonstrate the usefulness of such contextual help through two case studies of two visual data interfaces: Keshif and POD-Vis. We implemented and evaluated the help modes with two sets of participants, and found that directly selecting user interface elements was the most useful.
Understanding doctoral progress assessment in the arts and humanities
Authors: Sillence Matthew
Published: September 2022

This study examines the early-stage progress assessment for doctoral candidates at a British university through the perceptions of academic staff who acted as assessors. It was conducted in response to staff concerns about changes to the process that shortened the timescale for candidates to prepare and present their research for peer review. As well as having an impact on doctoral supervisors, there were implications for researcher developers and ‘third space’ professionals who supported candidates with research skills training. The findings of four in-depth interviews with assessors in the arts and humanities are discussed in the form of a reflective, ‘structured debriefing’. The results of these reflections form recommendations for practice that highlight the importance of conceptual frameworks for doctoral assessment, and the interpretations of criteria at institutional, disciplinary and individual levels. These could be emphasised by academic supervisors and third space professionals supporting doctoral candidates through this milestone.
Adaptive resize-residual deep neural network for fault diagnosis of rotating machinery
Authors: Zou Li , Lam Heung Fai , Hu Jun
Published: September 2022

Accurate fault diagnosis technology is essential for ensuring reliable operation of rotating machinery. However, complex conditions and various damage forms bring challenges to present diagnosis technology. In this study, a novel fault diagnosis method is proposed utilizing the newly developed adaptive resize-residual deep neural networks. The usage of the proposed method consists of three steps. First, the continuous wavelet transform is used to transfer the acquired vibration signals into time–frequency images. Second, the histogram equalization algorithm is applied to enhance the contrast of these images. Finally, the enhanced images are used as the input of newly proposed adaptive resize-residual networks, in which the adaptive resize block can deduce the dimensions of input data by self-learning and feed them into the residual block for pattern recognition. Two experimental cases are designed to evaluate the performance of proposed method. The experimental results indicate that the proposed adaptive resize-residual network obtains superior recognition accuracy and outperforms many state-of-the-art methods.
Long-term analysis of a savings program in elementary school
Authors: Davidson Jennifer A , Walstad William B
Published: September 2022

The prevalence of in-school savings programs (ISSPs) for children and youth is widespread, but research on their effectiveness is limited. This study investigates the long-term effects of an ISSP conducted in one U.S. elementary school. Survey data were collected on the financial behaviors of high school students, who participated in or did not participate in an ISSP while attending the same elementary school at the same time. The results from a probit analysis of data controlling for demographic variables showed that ISSP participants compared with non-participants were more likely to have a bank account in high school. They also were more likely to have opened a bank account before attending high school. Further results show that high school students with bank accounts are more likely to save regularly, indicating that ISSP contributes indirectly to saving regularly through its direct influence on getting students to open a bank account and open it early.
Optimizing Looking and Buying on Instagram: Tracing the Platformization of Advertising and Retail on Mobile Social Media
Authors: Carah Nicholas , Brown Maria-Gemma , Hickman Sarah
Published: September 2022

Over its first decade Instagram became central to Facebook’s dominance of audience and advertising markets. In this article, we critically examine how marketing and advertising trade press documented the development of advertising and retail on the platform. Instagram’s platformization involved formalizing relationships among users, influencers, creators, advertisers, retailers, and analytics services. The development of advertising and retail on the platform was characterized by open-ended third-party experimentation and innovation, which was gradually incorporated into, and controlled by, the platform. Advertisers and marketers increasingly approach the platform not just as an advertising service, but an end-to-end advertising, analytics and retail infrastructure. While much attention has been given to the promotional and influencer culture of Instagram, advertisers and marketers saw it as an opportunity to integrate advertising with retail. We argue that Instagram has platformized practices of looking and buying historically associated with department stores, malls, home shopping, and catalogs.
A hybrid approach to comparing parallel-group and stepped-wedge cluster-randomized trials with a continuous primary outcome when there is uncertainty in the intra-cluster correlation
Authors: Sarkodie Samuel K , Wason James MS , Grayling Michael J
Published: September 2022

Background/Aims:

To evaluate how uncertainty in the intra-cluster correlation impacts whether a parallel-group or stepped-wedge cluster-randomized trial design is more efficient in terms of the required sample size, in the case of cross-sectional stepped-wedge cluster-randomized trials and continuous outcome data.

Methods:

We motivate our work by reviewing how the intra-cluster correlation and standard deviation were justified in 54 health technology assessment reports on cluster-randomized trials. To enable uncertainty at the design stage to be incorporated into the design specification, we then describe how sample size calculation can be performed for cluster- randomized trials in the ‘hybrid’ framework, which places priors on design parameters and controls the expected power in place of the conventional frequentist power. Comparison of the parallel-group and stepped-wedge cluster-randomized trial designs is conducted by placing Beta and truncated Normal priors on the intra-cluster correlation, and a Gamma prior on the standard deviation.

Results:

Many Health Technology Assessment reports did not adhere to the Consolidated Standards of Reporting Trials guideline of indicating the uncertainty around the assumed intra-cluster correlation, while others did not justify the assumed intra-cluster correlation or standard deviation. Even for a prior intra-cluster correlation distribution with a small mode, moderate prior densities on high intra-cluster correlation values can lead to a stepped-wedge cluster-randomized trial being more efficient because of the degree to which a stepped-wedge cluster-randomized trial is more efficient for high intra-cluster correlations. With careful specification of the priors, the designs in the hybrid framework can become more robust to, for example, an unexpectedly large value of the outcome variance.

Conclusion:

When there is difficulty obtaining a reliable value for the intra-cluster correlation to assume at the design stage, the proposed methodology offers an appealing approach to sample size calculation. Often, uncertainty in the intra-cluster correlation will mean a stepped-wedge cluster-randomized trial is more efficient than a parallel-group cluster-randomized trial design.
Concurrent validity and intra-unit reliability of the Speedtrack X radar gun device for measuring tennis ball speed
Authors: Abdioglu Mekki , Akyildiz Zeki , Manuel Clemente Filipe
Published: September 2022

The aim of this study was two-fold: (i) to test the concurrent validity of the Speedtrack X radar device for measuring tennis ball speed in comparison to a Pocket radar gun and (ii) to test the intra-unit reliability of the Speedtrack X radar device for measuring tennis ball speed. A total sample of 116 tennis ball throws performed by the same machine were measured in a single session. All throws were simultaneously measured by one Pocket radar device (reference criterion) and one Speedtrack X radar gun. Reliability levels were calculated using Pearson’s correlation test ( r), the intra-class correlation test (ICC), and coefficient of variation (CV), while concurrent validity was tested using Bland-Altman and effect size (for measuring between-device differences). High correlation between the data obtained from the two devices was found ( r = 0.932, p < 0.001). The ICC of the measurements of the data obtained from the two devices is high ( r = 0.964, p < 0.001). The results allow us to conclude that the Speedtrack X radar gun is valid and reliable for measuring tennis ball speed.
Treatment of filum terminale pial arteriovenous fistulas in the sacral region: A case report and systematic review
Authors: Guo Yunbao , Yu Jinlu
Published: September 2022

Spinal filum terminale pial arteriovenous fistulas (FT PAVFs) are uncommon. Most FT PAVFs are located in the lumbar region; far fewer are located in the sacral region. Due to the rarity of sacral FT PAVFs, the precise surgical dissection and removal of these lesions are challenging. Here, we report an FT PAVF in the sacral region. The patient was a 45-year-old male who suffered from progressive weakness and numbness of the bilateral lower limbs; his symptoms gradually worsened. Digital subtraction angiography (DSA) showed an AVF at the sacral canal at the S3-4 level. Microsurgical treatment with intraoperative DSA was performed, and the FT PAVF was resected. After the operation, the patient gradually recovered. Follow-up magnetic resonance imaging revealed a recession in the dilation of the spinal cord venous plexuses. A literature review was also performed, and a total of 14 FT PAVFs of the sacral region were identified. The patients identified in the literature review had an average age of 58.9 ± 12.9 years, and 92.9% of the patients were male. Spinal cord edema was present in 85.7% of the FT PAVF patients. Regarding treatment, 64.3% of the FT PAVF patients underwent microsurgical resection, 28.6% patients underwent endovascular treatment, and 7.1% patients underwent a hybrid operation; good outcomes were achieved with all three methods. Therefore, FT PAVF of the sacral region is a unique lesion whose angioarchitecture needs to be identified carefully; prompt treatment is necessary, and microsurgery can yield good outcomes.

Background:

Thrombocytopenia is a common feature of myelofibrosis (MF), a myeloproliferative neoplasm driven by dysregulated JAK/STAT signaling; however, pivotal trials assessing the efficacy of ruxolitinib (a JAK1/2 inhibitor) excluded MF patients with low platelet counts (<100 × 109/L).

Objectives:

Determination of the maximum safe starting dose (MSSD) of ruxolitinib was the primary endpoint, with long-term safety and efficacy as secondary and exploratory endpoints, respectively.

Design:

EXPAND (NCT01317875) was a phase 1b, open-label, ruxolitinib dose-finding study in patients with MF and low platelet counts (50 to <100 × 109/L).

Methods:

Patients were stratified according to baseline platelet count into stratum 1 (S1, 75 to <100 × 109/L) or stratum 2 (S2, 50 to <75 × 109/L). Previous analyses established the MSSD at 10 mg twice daily (bid); long-term results are reported here.

Results:

Of 69 enrolled patients, 38 received ruxolitinib at the MSSD (S1, n = 20; S2, n = 18) and are the focus of this analysis. The incidence of adverse events was consistent with the known safety profile of ruxolitinib, with thrombocytopenia (S1, 50%; S2, 78%) and anemia (S1, 55%; S2, 44%) the most frequently reported adverse events and no new or unexpected safety signals. Substantial clinical benefits were observed for patients in both strata: 50% (10/20) and 67% (12/18) of patients in S1 and S2, respectively, achieved a spleen response (defined as ⩾50% reduction in spleen length from baseline) at any time during the study.

Conclusion:

The final safety and efficacy results from EXPAND support the use of a 10 mg bid starting dose of ruxolitinib in patients with MF and platelet counts 50 to <100 × 109/L.

Development of a nomogram for predicting lymph node metastasis in patients with urothelial carcinoma of the bladder
Authors: Abdelatif Ahmed , Ali Ahmed Issam , Kattan Michael , Small Robert P , Gabr Ahmed H
Published: September 2022

Background and Objectives:

Multiple nomograms have previously been described to predict recurrence, overall, and cancer-specific survival following radical cystectomy (RC) for urothelial carcinoma of the bladder (UCB).Our aim was to develop a nomogram for the preoperative prediction of lymph node (LN) metastasis in UCB.

Methods:

We prospectively collected data from 483 patients which were used in construction of the statistical model. The variables considered as predictors in the model were demographic, histopathological and radiological factors.

Results:

The full model containing all 12 covariates produced an AIC (Akaike information criterion) value of 448.9. After model selection T-stage, grade, CIS (carcinoma in situ), pathology, LV (lymphovascular) invasion and CT (computed tomography) were included as the most parsimonious model while retaining predictive accuracy. Ta in 82 (17%), T1 in 214 (445) and T2 in 187 (38%) patients. This model had an AIC of 436.4, indicating a significant improvement in model fit after the removal of unimportant predictors. The C-indices were 0.821 and 0.808 for the reduced model and the full model, respectively, indicating greater discrimination ability for the reduced model.The nomogram further emphasises the effect of CT and LV invasion on the risk of LN positivity. Specifically, regardless of all other variables, a patient with a CT will have 100 points more than a patient without a CT, corresponding to a difference in risk of approximately 40%. The odds of LN positivity for patients with a CT are 7.45 times that of patients without a CT, regardless of all other covariates. LV invasion, pathology, CIS and T-stage are also statistically significant ( p = 0.05).

Conclusion:

This nomogram is a preoperative prediction tool that uses different preoperative variables with acceptable predictive accuracy for LN metastasis in patients with BC.

Introduction

Integrated and patient-focused healthcare is urgently needed, and there is an important role for case managers in implementing them. However, the understanding of healthcare providers, especially nurse anesthetists, about the role of case managers is still varied and is often considered only as a complement to hospital accreditation. This study aimed to determine the factors that influence the nurse anesthetist’s perception of the role of the case manager.

Methods

This cross-sectional study involved 369 nurse anesthetists who were selected using cluster sampling. Data collection was done using Google Forms. Furthermore, the data were analyzed using multiple logistic regression to identify the factors that influence the nurse anesthetists’ perception of the role of the case manager.

Results

From a total of 369 respondents, most (60%) have a positive perception of case managers. Marital status (AOR = 2.3; 95% CI: 1.27–4.15) and knowledge (AOR = 3.2; 95% CI: 2.03–5.07) were significant predictors of the nurse anesthetist’s perception of the role of the case manager.

Discussion

Even though the majority of nurse anesthetists have positive perceptions, socialization to increase knowledge about case managers is needed to reduce misperceptions about the role of case managers.
It’s Not How You Say It, It’s What You Say: Ambient Digital Racism and Racial Narratives on Twitter
Authors: Agudelo Felipe I. , Olbrych Natalie
Published: September 2022

Social media has been used to disseminate hate speech and racism. Racist opinions can be disguised through a language that may appear to be harmless; however, it can be part of a racist rhetoric toward communities of color. This type of racist communication is called Ambient Digital Racism (ADR). Through a thematic analysis, this project sought to identify and analyze social media racist discourses on Twitter in the context of George Floyd’s death. This research examined original tweets posted during the time of the protests using three known counter Black Lives Matter (BLM) hashtags, namely, #WhiteLivesMatter, #BlueLivesMatter, and #AllLivesMatter. After the analysis, two themes emerged, namely, the discourse of oppressor’s reverse racism and the social criminalization of BLM. These themes described the narratives used by these groups to develop a racist digital discourse that goes unnoticed by social media regulations and policies and that leaves an open space to negotiate what constitutes acceptable race talk and what constitutes a racist discourse. It was found that both themes were grounded on White victimization, color-blind racism, and the dehumanization of BLM as a social and racial justice movement.
A Rare Presentation of Sarcomatoid Carcinoma of Duodenum: A Case Report

Published: September 2022

Sarcomatoid tumors are very rare biphasic tumors characterized by a mixture of malignant epithelial and mesenchymal cells that have been usually identified in the lungs with other documented cases in skin, bone, thyroid gland, salivary glands, breast, and genitourinary and gastrointestinal systems. They have an incidence estimated to be 0.5 to 0.8 per 100 000 per year. Three classic features include the presence of a genuine sarcomatous component, no transitional zone between carcinomatous and sarcomatous components, and immunohistochemistry of the sarcomatous component that is positive for mesenchymal markers and negative for epithelial markers. Sarcomatoid carcinoma of the gastrointestinal tract is rare but more commonly found within the stomach, gallbladder, and esophagus. Small bowel involvement is very rare.
