Transfer Penalty Estimation of Bus Passengers Considering Travel Frequency in Chengdu, China
Authors: Ye Pengyao , Deng Yifeng , Yang Hong , Fan Wenbo
Published: July 2022

The paper aims to examine bus passengers’ route choice behavior in the context of transfer penalty estimation. Methodologically, it leverages passengers’ stop-level trip information inferred from automatic vehicle location (AVL) and automated fare collection (AFC) data and compares the stop-level origin–destination (O-D) pairs with direct paths and transfer paths. The route choice models were established with the inclusion of normalized travel frequency as a key variable. A case study was performed using the trip data of adult card holders from the bus systems in Chengdu, China. The results show that the normalized travel frequency is a variable that makes an informative contribution to the explanation of passenger route choices. Specifically, passengers with higher travel frequency prefer to choose the transfer path. Moreover, the transfer penalty function in the context of the monthly travel frequency was obtained and shows that the travel frequency can reduce a passenger’s transfer penalty. Finally, the stabilities of the normalized travel frequency function and transfer penalty function were assessed using the trip data from the weekdays in four weeks with the results showing that the normalized travel frequency function is similar in shape. In addition, the relationship between a passenger’s monthly travel frequency and their familiarity with the bus network was discussed using the second derivative of the normalized travel frequency function.
Overfitting Prevention in Accident Prediction Models: Bayesian Regularization of Artificial Neural Networks
Authors: Fiorentini Nicholas , Pellegrini Diletta , Losa Massimo
Published: July 2022

In the present paper, we implemented the Bayesian regularization (BR) backpropagation algorithm for calibrating an artificial neural network (ANN) as an accident prediction model (APM) to be used on Italian four-lane divided roads. We chose the BR-ANN since it efficiently allows for dealing with small sample size and avoiding overfitting issues by adding a regularization term in the objective function to be minimized during training. Moreover, BR-ANNs are sparsely employed in road safety analyses, and their peculiarities deserve to be emphasized. In our work, the BR-ANN aims to predict the number of fatal and injury (FI) crashes across 236 road elements, for a total length of 78 km. The input features are road element length, horizontal and vertical alignment, cross-section geometry, operating speed, traffic flow, sight distance, and road area type (i.e., a categorical predictor accounting for the potential influence of merge and diverge influence areas). Training and test phases of the BR-ANN have been evaluated by determination coefficient ( R2), root mean square error (RMSE), overfitting ratio (OR), scatterplots, residuals analysis, and by the same ANN architecture trained with the gradient descent (GD) with momentum and adaptive learning rate backpropagation algorithm (GD-ANN). Results demonstrate that the BR-ANN markedly outperforms the GD-ANN, which suffers severe overfitting issues. Furthermore, BR-ANN does not overfit data (OR close to the unity), reports a satisfactory R2 (0.726), and shows a Gaussian residual distribution with zero mean. Therefore, road authorities could consider regularized ANNs for performing appropriate safety analyses, especially when dealing with small road sample sizes.
Examining Deviant Peer Association as a Moderator of the Relationship Between Borderline Personality Disorder Symptoms and Substance Use
Authors: Wojciechowski Thomas
Published: July 2022

Borderline personality disorder has been identified as a robust risk factor predicting substance use. There is a dearth of research examining how peer ties may condition this relationship. This study hypothesized that deviant peer association would amplify the relationship between Borderline personality disorder (BPD) symptoms and substance use. The Pathways to Desistance data were analyzed. Ordered logistic regression was used to analyze data. Results indicated that elevated levels of BPD symptoms predicted increased substance use frequency. Deviant peer association moderated the effects of BPD symptoms on marijuana use frequency and daily cigarette use. This moderation effect was in the opposite direction hypothesized, indicating that greater levels of deviant peer association dulled the effect on BPD symptoms on substance use. The unexpected effect indicated that youth reporting symptoms may be buffered against the impact of strain by having any peer relationships, even deviant ones.
Perceptions of School Resource Officers: Protectors or Prosecutors?
Authors: Almanza Matthew , Mason Makayla , Melde Chris
Published: July 2022

Since the 1990s there has been a significant rise in the number of police officers in schools. There have been growing concerns regarding the effects of school resource officers (SRO) on students’ long-term outcomes and whether or not they are an effective aspect of school safety. Public opinion, especially among key stakeholder groups, impacts policy and practice decisions, and, therefore, there is a need to examine and synthesize the current state of the literature on stakeholder perceptions of SROs. We conducted a systematic review of the literature regarding student, teacher, principal, parent, and SRO perceptions of the role and effectiveness of SROs. The findings across thirty-one publications suggest that key stakeholder groups largely report SROs as a positive presence within schools. Findings are mixed across studies, however, and key differences in perceptions of law enforcement among important school stakeholder populations are discussed.
Reorienting Lower Lateral Cartilages With Lateral Crural Struts: Aesthetic and Functional Benefits
Authors: Ambaram Rishal , Duplechain Kevin
Published: July 2022

Nasal tip shape and position play a major role in the aesthetic appearance of the nose. Cephalically oriented lower lateral cartilages (LLC) are associated with a broad boxy nasal tip. Reorienting cephalically positioned LLC with lateral crural strut grafts is a technique used to correct the nasal tip. An open approach surgical technique is described to evaluate the true orientation of the LLC and correct the boxy nasal tip. Five cases are shown with pre- and post-op pictures. The identical surgical technique is used in all cases with a variation in grafts necessary to create the desired esthetic result. All 5 described cases are on female patients. In all cases, reorientation of the lateral crura with lateral crural strut grafts were performed. In all, 4 of the 5 cases required a columellar strut graft, 3 cases required a shield graft to increase nasal tip projection and control the columellar-lobular angle, and 2 cases required spreader grafts for internal nasal valve support. All 5 cases required a variation of inter and intra-domal suture techniques to refine the nasal tip. A boxy nasal tip with supra-tip fullness is commonly associated with cephalically oriented LLC. Changing the orientation of the LLC to a more favorable angle and using lateral crural strut grafts can be used to not only correct the nasal tip deformity, but also facilitate projecting/de-projecting the nose, changing the rotation of the tip, and also supporting the external nasal valve. Reorienting cephalically oriented LLC is a versatile approach to reshaping the nasal tip. It is a technically demanding maneuver that when executed, allows complete control of the nasal tip complex. We have used this approach in many cases involving a boxy nasal tip with long ptotic tips and poorly supported external valves.

Published: July 2022

The bone conditions of mandibular bone vary from patient to patient, and as a result, a patient-specific dental implant needs to be designed. The basal dental implant is implanted in the cortical region of the bone since the top surface of the bone narrows down because of aging. Taguchi designs of experiments technique are used in which 25 optimum solid models of basal dental implants are modeled with variable geometrical parameters, viz. thread length, diameter, and pitch. In the solid models the implants are placed in the cortical part of the 3D models of cadaveric mandibles, that are prepared from CT data using image processing software. Patient-specific bone conditions are varied according to the strong, weak, and normal basal bone. A compressive force of 200 N is applied on the top surface of these implants and using finite element analysis software, the microstrain on the peri-implant bone ranges from 1000 to 4000 depending on the various bone conditions. According to the finite element data, it can be concluded that weak bone microstrain is comparatively high compared with normal and strong bone conditions. A surrogate artificial neural network model is prepared from the finite element analysis data. Surrogate model assisted genetic algorithm is used to find the optimum patient-specific basal dental implant for a better osseointegration-friendly mechanical environment.
Stochastic convergence of nitrogen oxides by fuel for OECD countries covering 1820–2019
Authors: Solarin Sakiru Adebola , Yilanci Veli , Gorus Muhammed Sehid
Published: July 2022

Addressing the challenges posed by pollutants is necessary to achieve the Sustainable Development Goals (SDGs) target 12 or achieve sustainable production and consumption patterns. Convergence assessment of air pollution provides information which can be beneficial to how to handle that air pollution across different countries. Nitrogen oxides (NOx) are one of the most popular air pollutants. However, the current empirical literature on environmental economics largely ignores the convergence of per capita NOx. For this reason, this study investigates the stochastic convergence of aggregate and fuel-specific per capita NOx emissions in 20 OECD countries. This paper employs a recently introduced panel stationarity test that considers both smooth and sharp structural changes in the data generation process. The panel results show that the convergence hypothesis is rejected only for NOx from light-oil consumption. However, country-specific results reveal substantial evidence for divergence in the sample countries when NOx emissions per capita generated through diesel consumption, light-oil consumption, and natural gas consumption are considered. Besides, we find that most of the series have convergent behaviour for aggregate NOx, NOx from biomass consumption, NOx from hard-coal consumption, NOx from heavy-oil consumption, and NOx from the process. The policy implications of the empirical results for proper environmental management are elucidated in the paper. Actions taken based on the convergence findings will likely lead to a decrease in NOx emissions per capita as the countries will converge towards a lower level of NOx emissions per capita, in line with SDG's target 12.

Published: July 2022

Tobacco use among youth in the South-East Asian region is quite prevalent. This study aims to examine if psychosocial factors (perceived loneliness, peer, and parental relationships) were associated with adolescent smoking, and whether the effects were different according to sex and age. Data came from the Global School-based Student Health Surveys collected between 2012 and 2015 in Brunei, Cambodia, Indonesia, Laos, Malaysia, Philippines, Thailand, Timor-Leste, and Vietnam. 64 578 (males = 48.5%) adolescents aged 13-18 completed the survey. Prevalence of past-month cigarette use was 10.6%. Adolescent smoking was associated with loneliness (OR = 1.75), lack of close friends (OR = 1.43), and lack of parental understanding (OR = 1.35). There was significant interactions between sex with loneliness, close friends, and parental understanding ( p < .001). Interactions indicated having no close friends is associated with smoking and is stronger for females than males. Conversely, loneliness was associated with smoking more strongly in males than females. Results indicate that psychosocial factors are linked to adolescent smoking in South-East Asia, suggesting a further need for research on the relation of psychosocial factors with smoking, and their underlying factors.
Verification of the fCAL turbo immunoturbidimetric assay for measurement of the fecal calprotectin concentration in dogs and cats
Authors: Enderle Lena L. , Köller Gabor , Heilmann Romy M.
Published: July 2022

The concentration of calprotectin in feces (fCal) is a clinically useful marker of chronic gastrointestinal inflammation in humans and dogs. No commercial assay is widely available to measure fCal in small animal medicine, to date. Thus, we verified the immunoturbidimetric fCAL turbo assay (Bühlmann) of fCal for canine and feline fecal extracts by determining linearity, spiking and recovery, and intra-assay and inter-assay variability. We determined RIs, temporal variation over 3 mo, and effect of vaccination and NSAID treatment. Observed:expected (O:E) ratios (x̄ ± SD) for serial dilutions of feces were 89–131% (106 ± 9%) in dogs and 77–122% (100 ± 12%) in cats. For spiking and recovery, the O:E ratios were 90–118% (102 ± 11%) in dogs and 83–235% (129 ± 42%) in cats. Intra- and inter-assay CVs for canine samples were ≤19% and ≤7%, and for feline samples ≤22% and ≤21%. Single-sample RIs were <41 μg/g for dogs and <64 μg/g for cats. With low reciprocal individuality indices, using population-based fCal RIs is appropriate, and moderate fCal changes between measurements (dogs 44.0%; cats: 43.2%) are considered relevant. Cats had significant (but unlikely relevant) fCal increases post-vaccination. Despite individual fCal spikes, no differences were seen during NSAID treatment. The fCAL turbidimetric assay is linear, precise, reproducible, and sufficiently accurate for measuring fCal in dogs and cats. Careful interpretation of fCal concentrations is warranted in both species during the peri-vaccination period and for some patients receiving NSAID treatment.
Coccidioidomycosis in 26 horses in California, USA: case series and review of the literature
Authors: Macías-Rioseco Melissa , Sheley Matthew , Ochoa Jennine , Carvallo-Chaigneau Francisco R. , Uzal Francisco A.
Published: July 2022

Coccidioidomycosis is a fungal disease caused by Coccidioides immitis or Coccidioides posadasii. We searched the records of the California Animal Health and Food Safety Laboratory from 1990 through 2020 for cases of coccidioidomycosis in horses. The selection criteria for these cases were: 1) live-born horses submitted for autopsy, and 2) a diagnosis of coccidioidomycosis was established, regardless of cause of death. During that time, 19,054 horses were received, and 26 cases (0.14%) of coccidioidomycosis were diagnosed in horses, of which 19 (73%) cases had pneumonia and/or pleuritis with or without lesions in other organs, and 7 (27%) cases had lesions only in organs other than the lungs (nasal mucosa, spleen, thoracic lymph nodes, heart, pericardial sac, liver, kidney, mediastinum, and/or mesentery). Pneumonia was diagnosed as the cause of death in 1,838 (9.64%) of the horses received; Coccidioides spp. was the cause of pneumonia in 19 (1.0%) of these animals. Horses have been reported to have low susceptibility to coccidioidomycosis, and the severity and chronicity of the disease can be variable. Lesions in our cases consisted of multifocal-to-coalescing pyogranulomas with intralesional fungal spherules. Coccidioidomycosis must be considered a differential diagnosis in cases of persistent cough, chronic weight loss, fever, and cases with a travel history to, or living in, a region considered endemic for coccidioidomycosis. Coccidioides spp. infection should also be considered when pyogranulomatous inflammation is found within lung, spleen, nasal mucosa, and lymph nodes of horses.

Authors: Aquino Katherine C.
Published: July 2022

Background: The COVID-19 pandemic created significant disruption within the educational setting, including the rapid shift to a fully online learning environment. Purpose: The purpose of this study was to explore how graduate students collaborated synchronously and reimagined an in-person academic service learning project into an asynchronous workshop format. Methodology/Approach: An explanatory single case study approach was used to explore how educational leadership doctoral students developed content for and transitioned the modality of an academic service learning project—a college readiness workshop for middle school students—during the COVID-19 pandemic. Findings/Conclusions: Overall, the development of and transition to a fully online workshop website format highlighted the importance and additional need for technology to support project content, the challenge of how to best incorporate audience engagement through an asynchronous platform, and the shift in roles and expectations of the graduate students throughout the workshop development process. Implications: Although this learning experience was adapted due to pandemic-related restrictions, this reimagined student-led project provided additional and unique opportunities for collaboration and technology integration that can be useful and applicable to the students’ post-lockdown lives.
The effect of axial length to basement-membrane opening to fovea distance on optical coherence tomography
Authors: Dersch Anne M. , Stucker Kathryn L. , Hajrasouliha Amir R.
Published: July 2022

Background

Optical Coherence Tomography (OCT) lateral scaling is influenced by axial length (AL). There is a need to incorporate a method to correct this measurement bias for accurate lateral OCT measurement.

Purpose

To identify the correlation of optic-nerve-to-fovea distance measurement to AL by OCT) as an internal factor for lateral scaling.

Methods

Using Heidelberg Spectralis OCT, distance from the basement membrane opening at the optic disc margin to the centre of the fovea (BMO-fovea distance) was measured in 135 eyes (77 subjects, ages 25–85). These measurements were correlated with AL measurements from Zeiss IOLMaster 700 using linear regression before and after correction for ocular magnification. Statistical analysis including Shapiro-Wilk test for normality, Pearson correlation, and multivariate analysis of the association between disc-fovea distance and AL was performed using Wizard statistical software for mac.

Results

After lateral scaling, the mean distance between the fovea and BMO was 3.60 ± 0.25 mm (median: 3.59; range 3.07–4.23 mm). There was a significant positive correlation between AL and Bennett's formula-corrected BMO-fovea distance (p <0.001, r = 0.354).

Conclusions

While there is significant variability in BMO-fovea distances, it is positively correlated with AL. A standard method is needed to improve the lateral scaling measurements in order to unify the results for enface OCT imaging.
Bilingual fiction series, genre conventions, and the economy of linguistic interaction in Israeli television
Authors: Ribke Nahuel
Published: July 2022

During the last decade, an increasing number of transnational and multilingual television shows have been produced, distributed, and consumed via global streaming platforms. The present study aims to examine bilingual fiction series through the analysis of two high-impact Hebrew-Arabic bilingual television shows, produced by the Israeli television industry: Arab Labor (2007–13) and Fauda (2015–present). While previous studies on these shows focused on the on-screen representation of the Jewish-Israeli and Palestinian population, and the Israeli-Palestinian conflict, the present article proposes a methodology for a quantitative and qualitative analysis of multilingual fiction series. Instead of a linear textual analysis, it suggests focusing on the genre conventions, televisual structure, and linguistic performances that made possible the complex amalgamation of the languages spoken in both series.
Risk Factors for Incomplete Aortic Remodeling With Stent-Assisted Balloon-Induced Intimal Disruption and Relamination in Aortic Dissection Repair for Complicated Aortic Dissection: Results of a Multicenter Study
Authors: Vecchini Fabien , Haupert Gautier , Baudry Anna , Mancini Julien , Dumur Lucie , Martinez Robert , Piquet Philippe , Picquet Jean , Gaudry Marine
Published: July 2022

Purpose:

The STABILISE technique has extended the treatment of aortic dissection to the thoracoabdominal aorta to achieve complete aortic remodeling. The aim of this multicenter study was to analyze the short- and midterm anatomical results of the STABILISE technique.

Materials and Methods:

We retrospectively analyzed patients treated with the STABILISE technique for complicated aortic dissection at 3 French academic centers. The aortic diameter at different levels was measured preoperatively, postoperatively, and at 1 year.

Results:

Between 2018 and 2020, 58 patients, including 47 men (average patient age: 60±11 years), were treated for type B aortic dissection in 34 cases and residual aortic dissection after type A repair in 24 cases. Three (5.2%) patients died postoperatively. Complete aortic remodeling (false lumen thrombosis and complete reapposition of the intimal flap) was achieved in 45/55 patients (81.8%), and false lumen thrombosis in the thoracic aorta was achieved in 52/55 patients (94.5%). At 1 year, with a computed tomographic (CT) scan available for 98.2% (54/55) of patients, we observed a significant decrease in the maximal thoracic aortic diameter and a significant increase in the aortic diameter at the bare-stent level compared with the preoperative CT scan. Severe aortic angulation (p=0.024) was a risk factor for incomplete aortic remodeling and significantly increased the aortic diameter (p=0.032). Chronic aortic dissection was associated with an increased risk of incomplete aortic remodeling (p=0.002).

Conclusions:

STABILISE for complicated aortic dissection results in false lumen thrombosis, complete reapposition of the intimal flap, and a decrease in the maximum aortic diameter in most cases. Incomplete reapposition of the intimal flap, which is more frequent in cases of chronic aortic dissection and severe aortic angulation, is a risk factor for a significant increase in the aortic diameter at the bare-stent level, and this risk justifies close follow-up and better patient selection.

Clinical impact

STABILISE technique for complicated aortic dissection results in false lumen thrombosis, complete aortic remodeling and a decrease in the maximum aortic diameter in most cases. At the bare-stent level, incomplete reapposition of the intimal flap, more frequent in chronic aortic dissection and severe aortic angulation, is a risk factor for an increased aortic diameter. This finding justifies close follow-up and better patient selection; thus, the STABILISE technique should be used with care in chronic aortic dissection and severe aortic angulation.
GP5 regulates epithelial–mesenchymal transition in breast cancer via the PI3K/AKT signaling pathway
Authors: Xiang Kui , Yanshan Hua , Chunmei Zhao , Minmin Guo , Yan Wang , Xiaojia Yi
Published: July 2022

Recent evidences have shown that glycoprotein V (GP5) protein, which is initially considered as an important adhesion molecule unique to the megakaryocyte line, was also specifically expressed in malignant human breast epithelial cells. However, its expression level and function are not clear. This study aimed to reveal the abnormal expression of GP5 in breast cancer (BC), research the associations between the GP5 abnormal expression and BC progression, and explore the molecular mechanism of GP5 in BC. Immunohistochemistry, Western blot (WB), and quantitative reverse transcription–polymerase chain reaction (RT-PCR) assays were used to determine the expression patterns of GP5 in BC tissues and cells. The expression profiles of GP5 in the Cancer Genome Atlas databases were analyzed by UALCAN. The GP5 knockdown and over-expression BC cell lines were constructed and confirmed by RT-PCR and WB. Transcriptome sequencing and KEGG database were performed to screen cellular processes and signal pathways. Phosphatidylinositol 3-kinase (PI3K)/AKT pathway was verified by RT-qPCR, and epithelial–mesenchymal transition (EMT) was confirmed by WB. The results indicated GP5 was highly expressed in BC tissues and might play an important role as a cancer-promoting gene in BC. The high expression of GP5 was significantly associated with higher nuclear grade, higher TNM stage, and human epidermal growth factor receptor 2 (HER2) negativity. GP5 may promote the proliferation, invasion, and metastasis of BC cells by activating PI3K/AKT signaling pathway to up-regulate the EMT. This study provides a new idea that GP5 was expected to become a potential molecular target for early BC clinic diagnosis and treatment.
Fixation of Distal Radius Fractures Under Wide-Awake Local Anesthesia: A Systematic Review
Authors: Gouveia Kyle , Harbour Eric , Gazendam Aaron , Bhandari Mohit
Published: July 2022

Background:

The purpose of this systematic review was to analyze the available literature on fixation of distal radius fractures (DRFs) under wide-awake local anesthesia no-tourniquet (WALANT), and to examine postoperative pain scores and functional outcomes, operative data including operative time and blood loss, and the frequency of adverse events.

Methods:

Embase, MEDLINE, Web of Science, and SCOPUS were searched from inception until May 2022 for relevant studies. Studies were screened in duplicate, and data on pain scores, functional outcomes, and adverse events were recorded. Due to methodological and statistical heterogeneity, the results are presented in a descriptive fashion.

Results:

Ten studies were included comprising 456 patients with closed, unilateral DRFs, of whom 226 underwent fixation under WALANT. These patients had a mean age of 52.8 ± 8.3 years, were 48% female, and had a mean follow-up time of 11.6 months (range: 6-24). Operative time for WALANT patients averaged 60.4 ± 6.5 minutes, with mean postoperative pain scores of 1.4 ± 0.6 on a 10-point scale. Studies that compared WALANT to general anesthesia found shorter hospital stays with most WALANT patients being sent home the same day, decreased postoperative pain scores, and decreased costs to the healthcare system. No adverse events were reported for WALANT patients.

Conclusions:

A growing body of literature reports that for closed, unilateral DRF, surgical fixation under WALANT is a safe and effective option. It allows patients to have surgery sooner, with improved pain scores and good functional outcomes, with a very low incidence of adverse events.
Exploring how power distance influences principal instructional leadership effects on teacher agency and classroom instruction in Oman: A moderated-mediation analysis
Authors: Hendawy Al-Mahdy Yasser F. , Hallinger Philip , Omara Ehab , Emam Mahmoud
Published: July 2022

Nations throughout the world have been engaged in efforts to redefine the role of principals to include instructional leadership. This is based upon research that has verified a positive indirect relationship between principal instructional leadership and student learning. This study tested a moderated mediation model of how the power distance orientation of teachers influences the effects of principal instructional leadership on teacher agency and classroom instruction. Data collected from 464 teachers in 65 middle schools in Oman were analysed using structural equation modelling, factor analysis and bootsrapping. The results supported a partial mediation model in which principal instructional leadership was associated with moderate direct and indirect effects through teacher agency on classroom instruction. In addition, lower power distance in principal–teacher professional relationships was associated with stronger effects of instructional leadership on teacher agency. These findings support assertions that instructional leadership is a relational process rather than a top-down bureaucratic form of leadership.
Inventing the American City: Dion Boucicault, John Brougham, and Transatlantic Urban Melodrama
Authors: Daly Nicholas
Published: July 2022

Two Dublin-born playwrights, Dion Boucicault and John Brougham (9 May 1810–7 June 1880), shadowed each other through the world of nineteenth-century theatre. In recent years, critical attention has often focused on their representations of racial and national identities, with Boucicault's plantation drama, The Octoroon, and Brougham's frontier parodies deservedly attracting attention. However, in this essay I want to spotlight their contribution to the local drama, and in particular their staging of urban America within the wider transatlantic context of staging the nineteenth-century city, in such plays as The Poor of New York (1857) and The Lottery of Life (1868). The city as it appears in their work is a place of spectacle, shapeshifting, and sheer illicit fun.

Implications of the findings are presented to offer guidance to principals who serve in high-poverty schools.
The Use of Indomethacin for Nocturnal Enuresis in Children With Nephrogenic Diabetes Insipidus: A Case Report and Review of the Literature
Authors: Hedin Erin , Alabbas Abdullah
Published: July 2022

Rationale:

Nocturnal enuresis is a common symptom of nephrogenic diabetes insipidus (NDI) in children. Published reports on the treatment of nocturnal enuresis in this population are scarce. Presenting concern of the patient: 2 brothers, aged 8 and 9 years, presented for outpatient pediatric nephrology follow-up. Despite being medically stable on their current medication regimen, they both experienced significant distress due to primary nocturnal enuresis, including decreased self-esteem and social stress.

Diagnoses:

The brothers had primary nocturnal enuresis related to their high urine output from NDI. Interventions: we describe a case of 2 brothers with NDI in whom indomethacin was added to their pharmacologic treatment specifically to address enuresis.

Outcome:

Both brothers experienced a significant decrease in the frequency of nocturnal enuresis and improvement in their perceived quality of life.

Teaching points:

Nocturnal enuresis is a bothersome symptom of NDI with adverse psychological effects. Indomethacin can improve nocturnal enuresis in some patients. Treatment with nonsteroidal anti-inflammatory drugs carries a risk of gastrointestinal and kidney side effects. We advocate for a patient-centered approach to the treatment of NDI which includes optimizing both the medical and the psychological needs of the patient.
#DomesticViolence During the COVID-19 Global Pandemic: An Analysis of Public Commentary via Twitter
Authors: López Gabriela , Bogen Katherine W , Meza-Lopez Richard J , Nugent Nicole R , Orchowski Lindsay M
Published: July 2022

The current study sought to characterize commentary regarding intimate partner violence during the COVID-19 (SARS-CoV-2) pandemic via the Twitter hashtags #DomesticAbuse and #DomesticViolence. A sample of 481 original, English-language tweets containing the hashtag #DomesticAbuse or #DomesticViolence posted across five consecutive weekdays from March 22 to March 27, 2020—during which many places were enacting lockdown mandates—was examined using thematic content analyses. Overall, Twitter users commented on potential increased rates of IPV, while adding details about abuse tactics that could be employed by perpetrators during the pandemic. Additionally, Twitter users disclosed personal experiences of IPV victimization. Four themes were identified, including (1) type of domestic violence (i.e. whether the violence was COVID-specific or general domestic violence), (2) commentary about IPV (i.e. general reflections, decentralizing and centralizing survivorhood), (3) perpetrator tactic (i.e. abuse tactic used by the perpetrator), and (4) institutions responsible (i.e. institutions responsible for providing services to survivors). Overall, the commentary on Twitter reflected an effort to raise awareness and share informational aid for potential victims/survivors of IPV. Data highlight the potential of social media networks in conveniently facilitating the sharing and spreading of useful resources to other users. Future research should examine whether resources shared via Twitter reach individuals who need them and empower individuals to garner support.
Gift-Giving as a Conversion Device in Online Marketplaces
Authors: Darr Asaf
Published: July 2022

The social foundations of the platform economy stand at the forefront of academic research in economic sociology, communication, and organization studies. Can a study of patterns of gift-giving in online marketplaces further our understanding of the social ties and normative structures underpinning trade? This study suggests that the answer is in the affirmative. Studies of gift-giving in offline markets assert that gifting is predicated on reciprocity and social obligation, and enables the constitution and reproduction of social ties that facilitate trade. This article presents a three-pronged theoretical argument. First, it extends the argument that gifting creates a social space that is open to manipulations and interpretations. Second, it asserts that gift-giving in the online marketplace should be viewed as a particular type of “market device,” an object that guides market actors how to make sense of their socio-economic actions. Third, the article argues that gifting operates as a “conversion device” providing buyers and sellers with a flexible material and symbolic resource that allows them to oscillate and convert between distinct moral frameworks that co-exist within the socio-cultural institution of gift-giving. Based on 54 in-depth interviews, this study finds that gifting flourishes around reputation systems, pointing to their central role in the platform economy. The role of gift-giving as a conversion device is developed and discussed, and the way sellers employ it to convert the normative framework depicting reputation systems as rational and calculative, into a framework highlighting reciprocity and obligation.
Relationship Between Satisfaction With Medical Care, Physical Health, and Emotional Well-Being in Adult Men: Mediating Role of Communication
Authors: Ramos-Vera Cristian , Saintila Jacksaint , Calizaya-Milla Yaquelin E. , Acosta Enríquez María Elena , Serpa Barrientos Antonio
Published: July 2022

Background:

Non-communicable diseases and psychiatric pathologies are the health problems that most affect the population in the United States.

Objective:

This study aimed to examine the mediating role of patient-centered communication (PCC) in the relationship between satisfaction with medical care, physical health, and emotional well-being in American men.

Methods:

A cross-sectional - predictive study was carried out. The variables analyzed were satisfaction with medical care, physical health, and emotional well-being. Information from the Health Information National Trends Survey Data (HINTS) was used; HINTS 5, cycle 3 (collected between January and June 2019) and 4 (2020). Data from 3338 men were considered (mean age: M = 55.40, SD = 19.53). Data analyses were carried out using structural equation modeling (SEM) to represent the statistical mediation model with latent and observable variables.

Results:

Analyses showed that the variables were significantly related ( P < .01). In the mediation model, there is evidence that satisfaction predicts communication (β = .764, P < .001) and this, in turn, is related to physical health (β = .079, P = .007) and emotional well-being (β = .145, P < .001). In addition, the standardized estimates of the structural multiple mediation model presented acceptable goodness-of-fit indices: χ2/gl = 2.24, CFI = 0.999, TLI = 0.999, RMSEA = 0.019 [90% CI: 0.013-0.022], SRMR = 0.018.

Conclusion:

Patient-centered communication plays a significant dual mediating role in the relationship between satisfaction with medical care, physical health, and emotional well-being, respectively. Therefore, PCC is essential in healthcare for American men.

Published: July 2022

Background:

Preoperative coracoid dimensions may affect the size of the bone graft transferred to the glenoid rim and thus the postoperative outcomes of Latarjet coracoid transfer.

Purpose:

To determine the effect of coracoid length and width as measured on preoperative magnetic resonance imaging (MRI) on outcomes after Latarjet treatment of anterior shoulder instability.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

Included were patients who underwent primary Latarjet surgery between 2009 and 2019 and had preoperative MRI scans and minimum 2-year postoperative outcomes. Longitudinal coracoid length was measured on axial MRI sequences as the distance from the coracoclavicular ligament insertion to the distal tip. Comparisons were made between shorter and longer coracoids and between narrower and wider coracoids. The outcomes of interest were recurrent instability, reoperation, complications, return to sport (RTS), and American Shoulder and Elbow Surgeons (ASES) score. Independent-samples t test, Mann-Whitney test, chi-square test, and Fisher exact test were used to compare outcomes between groups, and univariate correlation coefficients were calculated to evaluate the relationships between demographics and coracoid dimensions.

Results:

Overall, 56 patients were included (mean age, 28.4 years). The mean ± SD coracoid length was 21.6 ± 2.4 mm and width 10.0 ± 1.0 mm. Relative to patients with a longer coracoid (≥22 mm; n = 26), patients with a shorter coracoid (<22 mm; n = 30) had similar rates of recurrent instability (shorter vs longer; 6.7% vs 3.8%), complications (10.0% vs 15.4%), reoperation (3.3% vs 7.7%), and RTS (76.5% vs 58.8%) and similar postoperative ASES scores (85.0 vs 81.6) ( P ≥ .05 for all). Likewise, relative to patients with a wider coracoid (≥10 mm; n = 27), patients with a narrower coracoid (<10 mm; n = 29) had similar prevalences of recurrent instability (narrower vs wider; 6.9% vs 3.7%), complications (17.2% vs 7.4%), reoperation (3.5% vs 7.4%), and RTS (66.7% vs 68.4%) and similar postoperative ASES scores (87.1 vs 80.0) ( P ≥ .05 for all).

Conclusion:

Patients undergoing Latarjet coracoid transfer had similar postoperative outcomes regardless of preoperative coracoid dimensions. These findings should be confirmed in a larger cohort before further clinical recommendations are made.
The Boosters That Foster Creativity-Competencies Among MBA Students: Identifying and Modelling the Relationships

Published: July 2022

The higher education system, particularly management education institutions (MEIs), is recognized as a significant source of creative talent for organizations. Organizations have to carefully select the necessary talent from MEIs. In this light, MEIs would seek to maximize their students’ creativity competencies. This exploratory research study identifies the significant boosters of creativity-competencies employing a sample survey among 269 student-respondents on the verge of completing their MBA programmes. The relationships between the identified boosters were modelled using structural equation modelling.

The study found that adaptive-thinking and teamwork serve as the foundation for various other competencies, eventually fostering creativity competencies among the MBA students. The study restricts the assessment of creativity competencies concerning selected MBA institutions.

The model created will serve as the basis for developing creativity-competencies in management education. This study is new to examine the relationship among the individual competencies and traits boosting the creativity competencies and test the model in MEIs.
Serum cystatin C level can be used to estimate GFR in patients with solid tumors: Moderator Commentary
Authors: Vanhoutte Thomas , Sprangers Ben
Published: July 2022

The precise estimation of kidney function in patients with cancer is of great importance as deterioration and decreased kidney function are common and often kidney function-based dose adjustments of chemotherapy and other cancer-related medicines are necessary in these patients. There is an ongoing debate regarding the most suitable technique to determine kidney function based on the availability, accuracy, and validation of available glomerular filtration rate-estimating formulas in patients with cancer. Recent data suggest that cystatin-based formulas are superior to creatinine-based GFR formulas not only in the general population but also in patients with cancer.
A Systematic Review and Meta-analysis of Total Ankle Arthroplasty or Ankle Arthrodesis for Treatment of Osteoarthritis in Patients With Diabetes
Authors: Tarricone Arthur , Gee Allen , Chen Simon , De La Mata Karla , Muser Justin , Axman Wayne , Krishnan Prakash , Perake Vinayak
Published: July 2022

Background:

End-stage ankle osteoarthritis often requires one of 2 major surgical procedures: total ankle arthroplasty or ankle arthrodesis. Although the gold standard has been arthrodesis, patients with diabetes represent a unique cohort that requires additional considerations because of their decreased mobility and risk factors for cardiovascular complications. The purpose of this study is to review odds of major and minor adverse events for patients with diabetes and patients without diabetes in both total ankle arthroplasty and ankle arthrodesis.

Methods:

A total of 14 articles published between 2010 and 2020 were included in this review. Databases included PubMed, Scopus, MEDLINE/Embase, and Cochrane Library. Key words included ankle arthroplasty, total ankle arthroplasty, ankle arthrodesis, and diabetes.

Results:

The total number of procedures was 26 287, comprising 13 830 arthroplasty and 12 457 arthrodesis procedures. There was a significant association between patients with diabetes treated with arthrodesis and major adverse events (odds ratio [OR] 1.880, 95% CI 1.279, 2.762), whereas no significant association was observed between patients with diabetes treated with arthroplasty and major adverse events (OR 1.106, 95% CI 0.871, 1.404).

Conclusion:

This meta-analysis suggests patients with diabetes to be at significantly higher risk for major and minor adverse events after undergoing ankle arthrodesis. However, it suggests no significant differences in major adverse events between patients with diabetes and patients without diabetes having undergone total ankle arthroplasty.

Level of Evidence:

Level III, systematic review and meta-analysis.
Mobilizing ‘impermaculture’: Temporary urban agriculture and the sustainability fix
Authors: McCann Eugene , McClintock Nathan , Miewald Christiana
Published: July 2022

This paper addresses the alliance between some urban agriculturalists, developers, and the local state in promoting a certain type of ‘green urbanism’ through what we call ‘impermaculture’. Impermaculture is a model of urban agriculture whereby some urban farmers approach their impermanence – the possibility of their operations being replaced by higher value developments – less as a threat to be avoided, as traditionally understood in the literature, and more as an intended modus operandi to which they are committed. We discuss how they use lightweight and portable growing containers, planter beds, greenhouses, and livestock pens to operate within and enhance contemporary regimes of development in global North cities. We identify a spatio-temporal impermanence that stands in contrast to classic understandings of sustainability fixes as either a form of greenwashing or as spatial fixes involving the sinking of capital into construction of a ‘greener’ built environment. In what follows, we develop a conceptual framework that will facilitate these contributions and provide a language for discussing cases of impermaculture in Portland, Oregon and Vancouver, British Columbia. We discuss how urban agriculture is mobilized as part of the sustainability fix in the two cities. We first demonstrate how impermaculture emerges as a means of stabilizing the fix which is always prone to coming apart, or fracturing. We then draw on two examples – goat husbandry in Portland and temporary gardens in Vancouver – to demonstrate how urban agriculturalists are embracing and leveraging impermanence. This ‘impermaculture by design’ not only marks a new form of urban agriculture in the neoliberal city but shores up and temporally rescales the sustainability fix while providing urban agriculture initiatives stability.
