Combining Aesthetic Septorhinoplasty With Bioabsorbable Implants for Nasal Valve Insufficiency
Authors: Bueno Scott , Lam Blake Nguyen , Al-Obaidi Mohammed , Schlieve Thomas
Published: September 2021

This case report demonstrates the usage of a bioabsorbable nasal implant (BNI) in conjunction with an aesthetic septorhinoplasty. The authors uniquely chose to use this allograft due to inadequate autologous tissue secondary to previously performed temporomandibular joint arthroplasties. In addition to evaluating our case of a 22-year-old woman who received a BNI with an aesthetic septorhinoplasty, the authors performed a comprehensive literature review on the topic. Spanning 3 databases (Scopus, PubMed, and Cochrane), this review revealed 4 primary studies, totaling 349 patients. Each utilized nasal obstruction symptom evaluation (NOSE) scores to subjectively measure symptomatic improvement. We chose to use the NOSE questionnaire on our patient both preoperatively and postoperatively, in order to help demonstrate subjective improvement. The patient’s functional and aesthetic concerns were addressed in the operating room at Parkland Memorial Hospital under general anesthesia. Notably, the patient had previously had conchal cartilage harvested bilaterally, had insufficient septal cartilage for adequate grafting, and did not desire to undergo costal cartilage harvest. Therefore, all parties agreed to use a BNI to complete the functional component of the patient’s septorhinoplasty. This day-surgery first focused on the aesthetic septorhinoplasty followed by the placement of the BNI bilaterally. Following an uneventful postoperative course, our patient endorsed not only an aesthetic improvement but also an 88% functional improvement based on her NOSE score within 4 months of surgery. The authors were able to successfully integrate functional as well as aesthetic septorhinoplasty techniques under the constraints of having both limited autologous tissue and limited accepted options from the patient. For the patient and provider team, this newer allograft was confirmed to be effective and efficient. With the correct patient selection, this is an excellent adjunct procedure that can be quickly and safely performed either in conjunction with surgical rhinoplasty or as a standalone procedure by facial surgeons.
Behavior Sequence Analysis of Victims’ Accounts of Intimate Partner Violence
Authors: Keatley D. A. , Quinn-Evans L. , Joyce T. , Richards L.
Published: September 2021

Intimate partner violence (IPV) relates not only to physical forms of abuse, but also psychological, emotional, economic, and financial controlling behaviors. IPV is a dynamic, complex phenomenon that occurs over a relatively long period of time. While several measures of IPV exist, a method that can track the progression and escalation of such behaviors in relationships could offer more understanding and highlight key intervention points for individuals in such relationships. Behavior Sequence Analysis is used in the current research to map the chain and progression of behaviors in multiple real-world cases of IPV. Results indicate clear sequential clusters of behaviors such as physical and psychological abuse, and coercive controlling behaviors such as gaslighting, restricting movement, and removing freedoms. Overall, this research stands as a foundation framework to build a greater understanding of the processes and pathways of IPV, and offers workers in the field a novel method to assist with interviewing and intervening in such cases.
Multivariable predictive functional control of a compound power-split hybrid electric vehicle
Authors: Gao Ji , Lou Diming , Zhang Tong , Fang Liang , Zhang Yunhua
Published: September 2021

The Corun hybrid system (CHS) is a deeply coupled multiple-input–multiple-output (MIMO) hybrid system. The two inputs are the torques of the two motors. The two outputs are the carrier speed and transmission output torque. Using the traditional control method, the multi-objective control quality cannot be guaranteed because of the adopted static decoupling method and proportional–integral–derivative (PID) controllers. In this paper, the problems of the traditional control method are carefully analyzed, and a new control method is proposed. Instead of static decoupling, dynamic decoupling is adopted to improve the decoupling control effect. A predictive functional controller instead of a PID controller is adopted to deal with the pure delay caused by controller area network (CAN) communication. The tracking effect of the target value is further improved by predictive functional controllers. For the two decoupled subsystems, that is, the integral system and the second-order underdamped system, two predictive functional controllers are designed. The new control method was verified by simulations and tests. The results show that the new control method is superior to the traditional control method for CHS.
Intermittent cyclic load testing of polymer railway sleepers
Authors: van Belkom Aran , Pittrich Matthias , Lojda Vit
Published: September 2021

Before a new type of railway sleeper can be used in track, standardised laboratory tests must be carried out to determine its suitability. In addition to static load tests, assessments usually include cyclic load tests consisting of millions of load cycles, representing passing trains during the sleeper’s service life. In these laboratory tests, the loading cycles are applied continuously without resting periods to condense the test time. Traditional sleeper materials (timber, concrete) possess elastic properties for which such testing is appropriate. However, polymer sleepers exhibit viscoelastic properties, such as creep, a loading rate-dependent stiffness and heating due to non-linearity of the stress-strain curve. Subjecting polymer sleepers to continuous cyclic load tests with a load frequency reflecting permissible track speed can cause the sleeper to heat up. Intermittent testing with pauses between numbers of load cycles is proposed in this paper as a possible solution. The aim is to propose a laboratory loading procedure that adopts a traffic-resembling load of a railway line, considering an effective compromise between polymer visco-elastic behaviour and time consumption of the laboratory tests. The loading frequency is kept at the desired strain rate for track evaluation, giving a representative sleeper stiffness and strength assessment. Exemplary tests with varying test arrangements and loading procedures were performed to quantify the effects of intermittent loading in comparison with continuous loading. The proposed method eliminated most of the test-induced creep and heat accumulation, resulting in a more representative stiffness and strength assessment, which justifies the proposed intermittent testing for polymer sleepers. The proposed intermittent procedure is an optional test regime in ISO 12856-2 for polymer sleeper testing.
A Rare Case of Nasopharyngeal Glial Heterotopia in a Neonate
Authors: Singh Viveka , Nabar Neha , Badhwar Sanjiv , Joshi Preetha
Published: September 2021

Nasopharyngeal glial heterotopias is an extremely rare, nonhereditary, developmental malformation manifesting as a mass composed of mature neural tissue with no intracranial continuity. Glial heterotopia is a rare, non-neoplastic, extracranial midline malformation. Nasal glioma is the most frequently encountered entity among congenital nasal masses. Cases which are associated with intracranial extension are termed as encephalocele. It must be considered in the differential diagnosis of airway obstruction in neonates. Magnetic resonance imaging is mandatory to rule out intracranial extension. We report a rare case of heterotopic brain tissue in nasopharynx with no intracranial extension to attract attention to the diagnostic workup of nasopharyngeal obstruction in a neonate with respiratory distress. Clinical examination and radiological studies are diagnostic while early surgical excision and histopathological confirmation is the gold standard. This baby underwent complete intranasal endoscopic excision of mass on day 20 of life. The postoperative course was uneventful and the baby is growing well on follow-up. This case would be one of the few cases reported from India.
Do Donors provide higher Aid for Trade flows to Recipient-Countries that Diversify Export Products or Is It the Other Way Around?
Authors: Gnangnon Sèna Kimm
Published: September 2021

This article has explored whether Aid for Trade (AfT) flows that accrue to recipient-countries depend on the latter’s level of export product concentration. The analysis covers a sample of 132 countries over the period 2002–2017. The findings indicate that least developed countries (LDCs) receive higher AfT flows when they experience a rise in the level of export product concentration, while NonLDCs enjoy higher AfT flows when they diversify export products. Interestingly, higher amounts of AfT accrue to countries that diversify their export product basket towards manufacturing products, although different result patterns appear for the components of manufactured exports.

Proposed Specifiers for Conduct Disorder (PSCD): Factor Structure and Validation of the Self-Report Version in Community and Forensic Samples of Portuguese Youth
Authors: Ribeiro da Silva Diana , Sousa Ruben , Rijo Daniel , Mendez Beatriz , Tsang Siny , Salekin Randall T.
Published: September 2021

The Proposed Specifiers for Conduct Disorder (PSCD) was developed as a measure to assess the multifaceted model of psychopathic traits in children/youth (i.e., grandiose–manipulative [GM], callous–unemotional [CU], and daring–impulsive [DI] traits) in addition to Conduct Disorder (CD) symptoms. This study aims to test the psychometric properties of the PSCD-self-report version across community ( n = 648; 52.9% female) and forensic male youth ( n = 258) from the Portuguese population. Results supported a general factor and four specific factors (GM, CU, DI, CD), which was invariant across gender and sample type. Evidence for reliability, construct, and temporal validity were also found. Overall, the PSCD appears to be a promising measure for assessing psychopathic traits in youth from both community and forensic settings, which may contribute to the discussion around the conceptualization, assessment, predictive value, and clinical usefulness of the multifaceted model of psychopathy in youthful populations, particularly in its association with CD.

Published: September 2021

Older Latinxs engage in lower levels of leisure-time physical activity (PA) compared with non-Latinx Whites. Latin dance is a culturally relevant type of leisure-time PA that may engage older Latinx populations, particularly when coupled with mobile health technologies (mHealth). This single group pre–post feasibility study described the PA and health outcomes of middle-aged and older Latinxs participating in BAILA TECH—an intervention that combines the BAILAMOS Latin dance program with mHealth (Fitbit Charge 2, Fitbit app, and motivational text messages). Participants ( n = 20, Mage = 67 ± 7.1, female n = 15, 75%) were enrolled in the 16-week BAILA TECH intervention held twice a week. Participants received a Fitbit Charge 2 to assess PA at baseline, during the intervention, and postintervention. An mHealth platform (iCardia) collected Fitbit data and staff delivered weekly motivational and informational text messages. Participants completed questionnaires about PA, sedentary behavior, cardiorespiratory fitness, social support, quality of life, and cognitive function at baseline and postintervention. Paired t tests evaluated change in pre–post measures. There was a significant increase in device-assessed moderate-to-vigorous PA ( d = 0.69), self-reported light-leisure ( d = 1.91) and moderate-to-vigorous PA ( d = 1.05), moderate-to-vigorous leisure PA ( d = 1.55), predicted cardiorespiratory fitness ( d = 1.10), and PA social support ( d = 0.81 [family]; d = 0.95 [friends]) from baseline to postintervention. Although nonsignificant, there was a small effect on physical health–related quality of life ( d = 0.32) and executive function ( d = 0.29). These data describe an increase in PA levels and health-related outcomes of middle-aged and older Latinxs from participation in an mHealth-infused Latin dance intervention. An adequately powered trial is necessary to establish efficacy.
Restaurant Innovativeness and Brand Attachment: The Role of Memorable Brand Experience
Authors: Teng Hsiu-Yu , Chen Chien-Yu
Published: September 2021

The rise in restaurant failures suggests that a strong customer-brand attachment is essential for long-term viability. For restaurant managers, enhancing customer attachment to the restaurant brand is critical. However, few studies have examined the drivers of customer brand attachment. Our research investigated the association between innovativeness and brand attachment and the mediating role of memorable brand experience. A self-administered questionnaire survey method was adopted. Data were gathered from customers of coffee shops in Taiwan. The results revealed that out of four dimensions of restaurant innovativeness, menu innovativeness and experiential innovativeness exerted a positive influence on brand attachment through the creation of a memorable experience. Experiential innovativeness also exerted a direct positive influence on brand attachment. Few studies have explored the development of brand attachment from the perspective of innovativeness. Hence, our study may be the first to offer a framework that connects innovativeness, memorable brand experience, and brand attachment.
“That chart ain’t for us”: How Black women understand “obesity,” health, and physical activity
Authors: Justin Tori Alexis , Jette Shannon
Published: September 2021

In this article, we use qualitative methodology to explore how eight physically active Black women, who self-identify as “obese,” understand and experience health and physical activity, as well as how they position themselves in relation to discourses pertaining to “obesity” and Black femininity. Drawing on Foucauldian-informed critical obesity scholarship and Black feminist thought, we explore the ways in which physically active Black women concurrently resist, reproduce, and navigate racialized and gendered obesity discourse. Our findings advance critical obesity scholarship as we indicate that participants simultaneously adapt to, negotiate, and resist obesity discourse by re-defining health, questioning the BMI, and centering their desire for corporeal “thickness” as critical to their identity as Black women.
Feminism and the Politics of Resilience: Spectacular girls and the place of psychoanalytic approaches in feminist media and cultural studies during the Coronavirus crisis
Authors: Kennedy Melanie
Published: September 2021

In this review of Feminism and the Politics of Resilience, Angela McRobbie’s conceptualisation of the ‘perfect-imperfect-resilience dispositif’ is praised as offering a clear demarcation from McRobbie and others’ previous work on the earlier de-politicised and individualist era of postfeminism. It calls for more work in the field of feminist media and cultural studies to consider psychoanalytic approaches to questions around pleasure, affect and compulsion in girls’ and women’s popular media culture. In light of the Coronavirus crisis and with a reflection on the spectacular visibility of girls and former young female celebrities in recent mainstream media, this short essay explores two lines of inquiry in response to Feminism and the Politics of Resilience: first, what has the period of the pandemic done to the potent power of the p-i-r? And second, how might we be both careful to recognise the binaristic ways in which the girl subject is culturally constructed, while being sure not to reproduce such ‘ontologised dualisms’ of girlhood in our writing?
Ethers and esters as alternative fuels for internal combustion engine: A review
Authors: Hua Yang
Published: September 2021

Ether and ester fuels can work in the existing internal combustion (IC) engine with some important advantages. This work comprehensively reviews and summarizes the literatures on ether fuels represented by DME, DEE, DBE, DGM, and DMM, and ester fuels represented by DMC and biodiesel from three aspects of properties, production and engine application, so as to prove their feasibility and prospects as alternative fuels for compression ignition (CI) and spark ignition (SI) engines. These studies cover the effects of ether and ester fuels applied in the form of single fuel, mixed fuel, dual-fuel, and multi-fuel on engine performance, combustion and emission characteristics. The evaluation indexes mainly include torque, power, BTE, BSFC, ignition delay, heat release rate, pressure rise rate, combustion duration, exhaust gas temperature, CO, HC, NOx, PM, and smoke. The results show that ethers and esters have varying degrees of impact on engine performance, combustion and emissions. They can basically improve the thermal efficiency of the engine and reduce particulate emissions, but their effects on power, fuel consumption, combustion process, and CO, HC, and NOx emissions are uncertain, which is due to the coupling of operating conditions, fuel molecular structure, in-cylinder environment and application methods. By changing the injection strategy, adjusting the EGR rate, adopting a new combustion mode, adding improvers or synergizing multiple fuels, adverse effects can be avoided and the benefits of oxygenated fuel can be maximized. Finally, some challenges faced by alternative fuels and future research directions are analyzed.
Exploring game grammars: a sociosemiotic account of young people’s game-making practices
Authors: de Paula Bruno
Published: September 2021

This article investigates the relationship between young people’s game-making practices and meaning-making in videogames. By exploring two different games produced in a game-making club in London through a multimodal sociosemiotic approach, the author discusses how semiotic resources and modes were recruited by participants to realize different discourses. By employing concepts such as modality truth claims and grammar, he examines how these games help us reflect on the links between intertextuality, hegemonic gaming forms and sign-making through digital games. He also outlines how a broader approach to what has been recently defined as the ‘procedural’ mode by Hawreliak in Multimodal Semiotics and Rhetoric in Videogames (2018) can be relevant for promoting different and more democratic forms of meaning-making through videogames.
PAI-1 Polymorphisms Have Significant Associations With Cancer Risk, Especially Feminine Cancer
Authors: Wang Jiaxi , Peng Yuanyuan , Guo Hejia , Li Cuiping
Published: September 2021

Background:

The plasminogen activator inhibitor-1 (PAI-1) was found in many types of tumor cells, which involved in tumorigenesis. Some studies investigated the associations between PAI-1 polymorphisms and various cancers, but the results were inconsistent. So this study did a meta-analysis to assess the strength of relationship between PAI-1 and cancer.

Methods:

Articles that meet the requirements were searched from PubMed, EMBASE, MEDLINE, Scopus, CNKI, Wanfang and SinoMed electronic databases before June 17th 2021. Stata version 11.2 was performed to merge the odds ratios (ORs) values and calculate 95% confidence intervals (CIs). Stratified analyses were assessed on the basis of types of cancer, ethnicity and source of the control group. Heterogeneity and sensitivity analysis were tested, and publication bias was also estimated. A meta-regression analysis was applied to explore sources of heterogeneity. The false-positive report probabilities (FPRP) and the Bayesian False Discovery Probability (BFDP) test were used to assess the credibility of statistically significant associations.

Results:

Ultimately, in this study, 33 eligible reports were included with 9550 cases and 10431 controls for the rs1799889 polymorphism, 5 reports with 2705 cases and 3168 controls for the rs2227631 polymorphism, and 4 reports with 2799 cases and 4011 controls for the rs2227667 polymorphism. The ORs and 95% CIs showed a statistically significant relationship between rs1799889 4G>5G polymorphism and cancer risk, especially in feminine cancer. The term refers to cancers that occur in the female reproductive system, such as ovarian, breast, endometrial and cervical cancer. Moreover, there was no association observed for the PAI-1 promoter A>G polymorphism (rs2227631 and rs2227667). In further subgroup analyses of 4G>5G polymorphism (rs1799889), an increased susceptibility to cancer was observed in Caucasians group and some types of cancer groups.

Conclusions:

This article comes to a conclusion that the rs1799889 polymorphism might help to increase the risk of cancer; moreover, the susceptibility to feminine cancer is more evident.

Published: September 2021

Rare diseases affect nearly 300 million people globally with most patients aged five or less. Traditional diagnostic approaches have provided much of the diagnosis; however, there are limitations. For instance, simply inadequate and untimely diagnosis adversely affects both the patient and their families. This review advocates the use of whole genome sequencing in clinical settings for diagnosis of rare genetic diseases by showcasing five case studies. These examples specifically describe the utilization of whole genome sequencing, which helped in providing relief to patients via correct diagnosis followed by use of precision medicine.
‘It's a double whammy’: A qualitative study of illness uncertainty in individuals with Parkinson's disease in the context of COVID-19
Authors: Simpson Jane , Zarotti Nicolò , Varey Sandra , Anestis Eleftherios , Holland Carol , Murray Craig , Eccles Fiona JR
Published: September 2021

Objectives

The purpose of this study was to explore the experiences of individuals with Parkinson's through the theoretical lens of illness uncertainty during the first UK full lockdown period (March–June 2020) put in place due outbreak of the COVID-19 pandemic.

Methods

Individual semi-structured interviews were carried out via telephone in May 2020 with 10 individuals with Parkinson's (six men and four women) recruited from Parkinson's UK. Interviews were recorded and transcribed verbatim, and thematic analysis was adopted to analyse the resulting data.

Results

Four overarching themes emerged from the interview data: (1) COVID-19 amplifying existing fears and difficulties around the uncertainty of Parkinson's; (2) practical and psychological efforts to manage uncertainty; (3) benefit-finding as a way of acknowledging the positives of lockdown; (4) risk and future management in the context of uncertainty.

Discussion

Participants reported a range of implicit and explicit strategies to cope with the ‘double whammy’ of uncertainty caused by having Parkinson's during a global pandemic. While these were generally successful in maintaining well-being, it is important that such successful accounts are used to help inform novel strategies and interventions targeting individuals who might need additional support.

Six pyrophosphate analogues are prepared from zerumbone, murrayafoline A, acridone, and 4-hydroxycoumarin via 1,3-dipolar cycloaddition reactions. Their in vitro cytotoxic activity is evaluated against HepG2, LU-1, and HeLa cancer cell lines. Among them, diisopropyl ((ethoxy((4-((1-methoxy-3-methyl-9 H-carbazol-9-yl)methyl)-1 H-1,2,3-triazol-1-yl)methyl)phosphoryl)methyl)phosphonate (6a) and diisopropyl ((ethoxy((4-(((3-methyl-9 H-carbazol-1-yl)oxy)methyl)-1 H-1,2,3-triazol-1-yl)methyl)phosphoryl)methyl)phosphonate (6b) are found to show activity against HepG2, LU-1, and HeLa cancer cell lines, with IC50 values ranging from 7.31 to 17.88 μM.
A bibliometric study of news discourse analysis (1988‒2020)
Authors: Wang Guofeng , Wu Xiuzhen , Li Qiao
Published: September 2021

This study conducts a bibliometric analysis of news discourse analysis using CiteSpace to sketch its scientific landscape based on journal articles in English in the Scopus database from 1988 through 2020. The statistical analysis provides evidence for the interdisciplinarity of this area, and shows an upward trend in general over these years as well as an accelerating growth rate in the past decade. Findings also indicate that the problem-oriented CDA has gained the most popularity in this area since its emergence, and the appraisal framework, multimodality analysis, and discursive news values have become three hotspots of news discourse analysis. In addition, the authors in the West have contributed most in this area, but those from Chinese Mainland, Malaysia, South Africa, and Indonesia have gradually been an emerging powerhouse, which has added diversity in topics and will enhance equality and promote dialogue between different communities, ethnics, and races across the globe.
Quercetin Supplementation and COVID-19
Authors: Boretti Alberto
Published: September 2021

Quercetin is an antioxidant, detox, and anti-inflammatory agent, which may help lower inflammation as well as reduce toxic effects. It has been argued that vaccines have potential risks of local and systemic inflammatory responses and toxic effects of synthetic nucleosides and components for vaccine delivery. Administration of substances such as Quercetin may then mitigate these effects. It has similarly been argued that substances such as Quercetin may reduce the efficacy of vaccines, which works in building an immune response to produce antibodies. Under this other perspective, the assumption of Quercetin should be avoided when receiving vaccines. The purpose of this paper is to analyze the information available to understand if Quercetin may mitigate the damage from novel coronavirus disease 2019 (COVID-19) vaccines, or also reduce their efficacy.
Discovering needs for digital capitalism: The hybrid profession of data science
Authors: Dorschel Robert
Published: September 2021

Over the last decade, ‘data scientists’ have burst into society as a novel expert role. They hold increasing responsibility for generating and analysing digitally captured human experiences. The article considers their professionalization not as a functionally necessary development but as the outcome of classification practices and struggles. The rise of data scientists is examined across their discursive classification in the academic and economic fields in both the USA and Germany. Despite notable differences across these fields and nations, the article identifies two common subjectivation patterns. Firstly, data scientists are constructed as hybrids, who combine generally conflictive roles as both generalists and specialists; technicians and communicators; data exploiters and data ethicists. This finding is interpreted as demonstrating a discursive distinction between data scientists and other competing and supposedly more one-dimensional professionals, such as statisticians or computer scientists. Secondly, the article uncovers a discursive construction that interpellates data scientists as discoverers of needs. They are imagined as explorative work subjects who can establish growth for digital capitalism by generating behavioural patterns that allow for personalization, customization and optimization practices.
A study of the functions of political appointees from a comparative perspective
Authors: Makita Jun
Published: September 2021

In this article, the functions of political appointees have been classified by an index on the relation between politics and bureaucracy. Based on that classification, the real states of four democracies, the United States, the United Kingdom, France and Japan, have been examined. From this study, the causation consisting of the politico-administrative relation (concretely, the insider-outsider factor and the line-staff factor), the independent value, and the political appointees' functions (advice, decision-making and interface between politicians and civil servants), the dependent value, has been confirmed. Through this examination from a comparative perspective, a proposal of generalization about the political appointees' functions has been presented.
Using a Critical Hip-Hop School Counseling Framework to Promote Black Consciousness Among Black Boys
Authors: Washington Ahmad R.
Published: September 2021

In this article, I outline an approach for critical hip-hop school counseling (CHHSC) for novice and tenured school counselors to use when working with Black boys. Various facets of hip-hop culture (e.g., music, hip-hop scholarship) can sharpen Black boys’ conscientização ( Freire, 1996 ) and help them discern how interconnected social institutions (e.g., political systems, traditional schools) are grounded in anti-Black discourses and practices that endanger Black life (Baldwin, 1963; Dumas, 2016). The article begins with an operational definition of hip-hop culture. From there, I connect dissident ideas within hip-hop culture to the ways social justice has been operationalized in education and counseling, school counseling in particular. I conclude with suggestions and resources school counselors can research and integrate when using this approach with Black boys in middle and secondary school settings (Grades 6–12).
K–12 School Counselors Utilizing Critical Race Theory to Support the Racial Identity Development and Academic Achievement of African American Males
Authors: Appling Brandee , Robinson Shanel
Published: September 2021

This article examines the role of racial identity development in the academic achievement of African American adolescent males. Through the lens of critical race theory (CRT), we highlight how K–12 school counselors may support and enhance the schooling experiences of African American males by understanding and acknowledging how racial identity development may impact academic achievement. A focus on CRT in education emphasizes the continual persistence of racism ingrained in K–12 education located within the educational opportunities, curriculum, representation, and teacher perception of African American males. We offer insight into how school counselors may work to decrease barriers to achievement by analyzing the effect race and gender have on the identification, retention, and underachievement of their African American male students.
“Double-Pulley” Dual-Row Technique for Arthroscopic Fixation of Large Bony Bankart Lesion: Minimum 2-Year Follow-up With CT Evaluation
Authors: Guo Siyi , Jiang Chunyan
Published: September 2021

Background:

A “double-pulley” dual-row technique had been applied for arthroscopic fixation of large bony Bankart lesion in which the fragment has a wide base.

Purpose:

To investigate clinical outcomes and glenoid healing after arthroscopic fixation of bony Bankart lesion using the double-pulley dual-row technique.

Study Design:

Case series; Level of evidence, 4.

Methods:

A total of 25 patients were included in this retrospective study. The American Shoulder and Elbow Surgeons (ASES) score, pain visual analog scale (VAS) score, and range of motion of the affected shoulder were assessed. Radiographs and computed tomography (CT) scans (preoperatively, immediately after surgery, and at 1 year postoperatively) were performed to evaluate arthritic changes (Samilson-Prieto classification) and glenoid size. The intraobserver reliability of the CT measurements was analyzed.

Results:

At a mean follow-up of 3.4 years, the mean ASES and VAS scores were 94.87 ± 5.02 and 0.48 ± 0.59, respectively. Active forward elevation, external rotation with the arm at the side, and internal rotation were 165.80° ± 11.70°, 33.20° ± 8.02°, and T9 (range, T6-S1), respectively. No patient reported a history of redislocation or instability. The intraobserver reliability of the CT measurements was moderate to excellent. The mean preoperative size of the bony fragment was measured as 23.4% ± 7.8% of the glenoid articular surface. The quality of the reduction was judged to be excellent in 13 (52%) cases, good in 8 (32%), and fair in 4 (16%). The mean immediate postoperative glenoid size was 96.8% ± 4.3%, and bone union was found in all cases. There were no significant differences between reconstructed and immediate postoperative glenoid size or between preoperative and final Samilson-Prieto grades.

Conclusion:

The arthroscopic double-pulley method was a reliable technique for the fixation of large bony Bankart lesions with a wide base. Satisfactory results can be expected regarding the restoration of the glenoid morphology and stability of the shoulder. High healing rate and good shoulder function can be achieved. No radiological evidence of cartilage damage caused by suture abrasion was found at 2- to 5-year follow-up.
Home Thrive ScaleTM: Case Management Tool Towards Preventing Family Separation and Ensuring Children Thrive in Family-based and Alternative Care Options
Authors: Choudhury Audria
Published: September 2021

Case management can be a complex process where multiple factors must be considered for the safety and well-being of a child in any care option. Miracle Foundation’s proprietary Home Thrive ScaleTM is a strengths-based assessment tool that makes it easier to identify strengths, risks and address areas of support within a family home over time. A home’s safety is measured based on five well-being domains—family and social relations, health and mental health, education, living conditions and household economy—with the child and family’s thoughts at the core. Intervention options are then offered to put assessments into action. The tool serves to both prevent family breakdowns and reintegrate children from institutions back into families (or other family-based or alternative care options). Here, we provide an overview of the tool, including its purpose, set-up and functionality within a case management system. The use of the tool is illustrated with the COVID-19 situation in India where masses of children were rapidly placed from institutions back into families without preparation.

Guidelines aim to standardise and optimise asthma diagnosis and management. Nevertheless, adherence to guidelines is suboptimal and may vary across different healthcare professional (HCP) groups.

Further to these concerns, this European Respiratory Society (ERS)/European Academy of Allergy and Clinical Immunology (EAACI) statement aims to: 1) evaluate the understanding of and adherence to international asthma guidelines by HCPs of different specialtiesviaan international online survey; and 2) assess strategies focused at improving implementation of guideline-recommended interventions, and compare process and clinical outcomes in patients managed by HCPs of different specialtiesviasystematic reviews.

The online survey identified discrepancies between HCPs of different specialties which may be due to poor dissemination or lack of knowledge of the guidelines but also a reflection of the adaptations made in different clinical settings, based on available resources. The systematic reviews demonstrated that multifaceted quality improvement initiatives addressing multiple challenges to guidelines adherence are most effective in improving guidelines adherence. Differences in outcomes between patients managed by generalists or specialists should be further evaluated.

Guidelines need to consider the heterogeneity of real-life settings for asthma management and tailor their recommendations accordingly. Continuous, multifaceted quality improvement processes are required to optimise and maintain guidelines adherence. Validated referral pathways for uncontrolled asthma or uncertain diagnosis are needed.
Comparison of enhanced recovery after surgery protocol and conventional approach after laparoscopic transperitoneal radical prostatectomy: a retrospective analysis
Authors: Guleser Ahmet Semih , Basaga Yasar , Karadag Mert Ali
Published: September 2021

Background

Although open radical prostatectomy has been used in the treatment of localized prostate cancer for a long time, minimally invasive surgical approaches such as laparoscopic radical prostatectomy and robot-assisted radical prostatectomy have recently gained importance in order to improve postoperative results and shorten hospital stay. Although the enhanced recovery after surgery (ERAS) protocol was first defined for gastrointestinal surgeries in 2001, it has now been used in gynecological, orthopedic, thoracic and urological surgeries. In our study, we aimed to compare the results of the ERAS protocol with the conventional approach in patients who underwent laparoscopic radical prostatectomy.

Methods

There is a retrospective analysis of 70 patients who underwent laparoscopic radical prostatectomy at Kayseri City Hospital between May 2018 and January 2021. Data were analyzed using the Statistical Package for the Social Sciences (SPSS) for Windows, version 25.0 (IBM SPSS, Armonk, NY, USA). Seventy patients were included in the study. While 48 patients who underwent perioperative care with the traditional approach were included in the conventional group, 22 patients were included in the ERAS group. Age, comorbidities, preoperative PSA level, digital rectal examination findings, preoperative imaging, extra prostatic spread and lymph node involvement, location of tumors, time between biopsy and surgery, lymphadenectomy status, and histopathological findings of transrectal ultrasound biopsy and prostatectomy specimens were recorded for each patient. Initiation of enteral feeding, time to first defecation, duration of antibiotic use, ileus development rate and length of hospital stay (LOS) were compared for both groups.

Results

The mean age of 48 patients in the conventional group was 63.37 ± 7.01 years, while the mean age of 22 patients in the ERAS group was 66.36 ± 5.31 years (p = 0.080). Although the first defecation time was shorter in the ERAS group (4.75 ± 3.21 vs. 3.73 ± 2.12 days, p = 0.179), there was no statistically significant difference. Ileus developed in 10 (20.8%) patients in the conventional group and 2 (9.1%) in the ERAS group. Use of antibiotics in the postoperative period in the conventional group (5.83 ± 3.62 vs. 3.18 ± 2.42 days, p = 0.003) and LOS (7.92 ± 3.26 vs. 5.91 ± 2, 15 days, p = 0.011) were statistically significantly longer.

Conclusion

In summary, ERAS protocol is associated with short LOS, time to initiation of enteral feeding and duration of antibiotics use. There was no statistically significant difference in the rate of ileus and time to first defecation between the two groups. Randomized prospective studies on heterogeneous and larger patient groups are needed to confirm our findings.

Background

Isolated scrotal gunshot injuries are uncommon. Even more so when they are self-inflicted. The extent of the injury is determined by the caliber of the weapon. Established management protocols when followed yields excellent results.

Case presentations

We present two male patients, aged 41 and 51 years old, who sustained gunshot injuries to the scrotum following accidental discharges from hand guns stored in their trouser pockets. The first (41 years) sustained grade 5 American Association for Surgery of Trauma (AAST) left testicular injury and was managed by unilateral orchidectomy. The second (51 years old) sustained bilateral grade 4 AAST testicular injuries and had both testes salvaged by primary repair after meticulous debridement.

Conclusion

Isolated scrotal gunshot injuries can occur when low velocity guns are placed adjacent to the genitalia and accidentally discharged. The testes are endangered and can be devitalized requiring orchidectomy or salvaged by meticulous debridement and primary repair when viability is not compromised.
The practical part of train driver education: experience, expectations, and possibilities
Authors: Olsson Niklas , Lidestam Björn , Thorslund Birgitta
Published: September 2021

Objectives

The internship period of the Swedish train driver education was examined in terms of which types of situations can be sufficiently encountered in order to develop expertise to handle them safely and efficiently, and to quantify and specify the gap in expertise between expert and novice drivers in terms of risk of error and time efficiency. Focus
was on special cases (i.e., situations that occur rarely but may cause severe accidents if not handled correctly and efficiently).

Methodology

Data on which situations and special cases a driver's student can be expected to experience during the internship period were collected via a web-based questionnaire. Also, ratings of expectations on novice and expert drivers were obtained from train driver educators, employers, and instructors with the purpose of comparing the expectations with the novices practical experience.

Results and conclusions

The main results suggest that many special cases are generally insufficiently practiced during the internship and therefore should be practiced in simulators; that both experienced and novice drivers prioritize safety over efficiency; and that expectations on novice drivers are realistic considering their limited professional expertise.
MiR-200c-3p promotes ox-LDL-induced endothelial to mesenchymal transition in human umbilical vein endothelial cells through SMAD7/YAP pathway
Authors: Mao Yongzhong , Jiang Ling
Published: September 2021

Background

Endothelial to mesenchymal transition (EndMT) participates in the progression of atherosclerosis (AS). MiR-200c-3p has been implicated in EndMT. However, the functional role of miR-200c-3p in AS remains largely unknown. Here, we demonstrated the critical role of miR-200c-3p in regulating EndMT in AS.

Methods

ApoE−/− mice were fed with high-fat diet to establish AS mouse model, and human umbilical vein endothelial cells (HUVECs) were treated with oxidized low-density lipoprotein (ox-LDL) to mimic AS cell model. The expression of miR-200c-3p, SMAD7 and YAP in ApoE−/− mice and HUVECs was detected by quantitative real-time PCR. Rhodamine phalloidin staining and Western blot were performed to observe cell morphology and EndMT marker expression of HUVECs. Luciferase reporter assay and Co-Immunoprecipitation were performed to verify the relationship among miR-200c-3p, SMAD7, and YAP.

Results

MiR-200c-3p was highly expressed, and SMAD7 and YAP were down-regulated in the aortic tissues of ApoE−/− mice and ox-LDL-treated HUVECs. MiR-200c-3p overexpression promoted the transformation of ox-LDL-treated HUVECs from cobblestone-like epithelial phenotype to a spindle-like mesenchymal phenotype. Meanwhile, miR-200c-3p up-regulation repressed the expression of endothelial markers CD31 and vWF and promoted the expression of mesenchymal markers α-SMA and vimentin in the ox-LDL-treated HUVECs. MiR-200c-3p inhibited SMAD7 and YAP expression by interacting with 3′ untranslated region of SMAD7. Moreover, miR-200c-3p promoted EndMT in ox-LDL-treated HUVECs by inhibiting SMAD7/YAP pathway.

Conclusion

This work demonstrated that MiR-200c-3p promoted ox-LDL-induced EndMT in HUVECs through SMAD7/YAP pathway, which may be important for the onset of atherosclerosis.

Published: September 2021

Background

The risk factors of in-stent restenosis (ISR) among coronary artery disease (CAD) patients with syphilis after percutaneous coronary intervention (PCI) are not fully understood. Therefore, this study aimed to elucidate not only the risk factors of ISR among CAD patients with syphilis after performing PCI, but also the population attributable risk percentage (PAR%), which is used to quantify the proportion of ISR that could be eliminated if particular risk factors are not present.

Methods

Evaluation of the prevalence, risk factors, and their PAR% for ISR among CAD patients with syphilis undergoing PCI was conducted retrospectively at Beijing Ditan Hospital. CAD patients with syphilis underwent PCI from August 2010 to August 2019 and received a diagnosis, coronary angiography, PCI, and periodical follow-up. The clinical, laboratory, and imaging data were reviewed and summarised anonymously from electronic medical records. The chi-square or Fisher exact test was used in data analysis.

Results

Among 114 CAD patients with syphilis undergoing PCI, ISR occurred in 18 patients (15.78%). The multivariate Cox regression model indicated that average stent length ≥ 35 mm (adjusted hazard ratio [HR] = 4.47, 95% confidence interval [CI] = 1.30–15.44, p = 0.018) and titres of the toluidine red unheated serum test (TRUST) > 1:16 (adjusted HR = 3.72, 95% CI = 1.22–11.36, p = 0.021) were associated with an increased risk of ISR, while successful antisyphilitic treatment (adjusted HR = 0.12, 95% CI = 0.02–0.95, p = 0.045) was protective predictor of ISR among these patients. The PAR% values of particular risk factors associated with ISR including average stent length ≥ 35 mm, titres of TRUST > 1:16, and successful antisyphilitic treatment were 12.2%, 24.0%, and -39.6%, respectively, among these patients.

Conclusions

Preventing the occurrence of ISR among CAD patients with syphilis undergoing PCI requires clinical intervention. Our results indicated that carefully evaluating the length of the vessel lesion to determine whether the stent length is < 35 mm, prioritising the clinical intervention for titres of TRUST > 1:16, and providing successful antisyphilitic treatment could reduce the risk of ISR occurrence.
