New Experimental Evidence on Anti-Asian Bias in White Parents’ School Preferences
Authors: Mellon Greer , Siegler Bonnie
Published: June 2023

Existing research has found evidence of widespread anti-Asian bias in the United States, yet limited work has examined whether anti-Asian biases affect parents’ school preferences. In this article, using a conjoint experiment, we examine White parents’ views on schools with varying percentages of Asian students. We find that respondents strongly prefer schools with fewer Asian students, and we examine potential mechanisms that may explain these preferences. We do not find evidence that our results are driven by academic stereotypes. Instead, participants anticipated less student-level “fit” and less “commonality” with parents at schools with larger Asian populations, in line with past research on anti-Asian bias and stereotypes. Our findings extend existing literature on race and school choice and speak to the importance of addressing anti-Asian discrimination in U.S. educational settings.
The Right to Live in Peace: Musical Responses to Violence in the 2019 Chilean Uprising
Authors: Party Daniel
Published: June 2023

Two protest songs created within the first month of the 2019 Chilean uprising were intended as explicit statements against violence and in favor of peace, but they voiced different understandings of violence and proposed different ways out of the conflict. The artists behind each song argued that their recordings were nonpartisan, cutting across traditional left-right divides. The songs’ use and reception, however, shows that for Chilean audiences these songs conveyed a clear political cleavage through their lyrics, music, and audiovisual content. More broadly, consideration of music in the Chilean uprising foregrounds the ways in which the uses of music have changed since the classic era of protest song of the 1960s and 1970s.

Dos canciones de protesta creadas en el primer mes del levantamiento chileno de 2019 pretendían ser declaraciones explícitas contra la violencia y a favor de la paz, pero expresaban distintas interpretaciones de la violencia y propusieron diferentes formas de salir del conflicto. Los artistas detrás de cada canción argumentaron que sus grabaciones no eran partidistas, cortando así a través de las tradicionales divisiones de izquierda y derecha. El uso y recepción de las canciones, sin embargo, muestra que, para el público chileno, dichas piezas transmitían una clara división política a través de sus letras, música y contenido audiovisual. En términos más generales, considerar el aspecto musical en el levantamiento chileno pone en relieve las formas en que los usos de la música han cambiado desde la era clásica de la canción de protesta de las décadas del sesenta y setenta.
A Tale of Two Crashes: Pandemic Politics in Brazil and Peru
Authors: Cameron Maxwell A. , Hurtado Veronica , Sosa Villagarcia Paolo , Gombata Marsílea
Published: June 2023

Health care system preparedness did not correlate consistently with policy performance during the COVID-19 pandemic. In Brazil and Peru, the preparedness of health care systems was inversely related to the perceived political risks associated with the spread of COVID-19. Lack of preparedness of the Peruvian health care system heightened fears of a system crash and thus encouraged a more stringent initial response by President Martín Vizcarra, the political actor both most accountable and able to act. In Brazil, the combination of a robust health care system and the highly fragmented political system enabled President Jair Bolsonaro to politicize the pandemic and prioritize economic growth while blaming his opponents for what he considered excessively costly public health measures.

La preparación del sistema de atención de salud no se correlacionó de manera consistente con el desempeño de las políticas durante la pandemia de COVID-19. En Brasil y Perú, la preparación del sistema de salud estaba inversamente relacionada con los riesgos políticos percibidos asociados a la propagación de COVID-19. La falta de preparación del sistema de salud peruano aumentó los temores de un colapso del sistema de atención médica y, por lo tanto, dio lugar a una respuesta inicial más estricta por parte del presidente Martín Vizcarra, el actor político más responsable y capaz de actuar. En Brasil, la combinación de un sistema de salud robusto y un sistema político altamente fragmentado permitieron que el presidente Jair Bolsonaro politizara la pandemia y priorizara el crecimiento económico mientras culpaba a sus oponentes por lo que consideraba medidas de salud pública excesivamente costosas.
“They were here, and they still matter”: A qualitative study of bereaved parents legacy experiences and perceptions
Authors: Jones Maile T , Albanese Elena , Boles Jessika C
Published: June 2023

Background:

Legacy building interventions are used in pediatric healthcare settings to help families cope with difficult healthcare experiences and typically reserved for intentional use at or near the end of a child’s life. However, little is known about how bereaved families perceive the concept of legacy that these practices are meant to address. Emerging research challenges the view of legacy as a standardized, handheld keepsake item but rather as a summation of qualities and experiences that affect those left behind. Therefore, more research is needed.

Aim:

To explore the legacy perceptions and experiences of bereaved parents/caregivers in an effort to inform legacy-oriented interventions in pediatric palliative care.

Design:

In this qualitative, phenomenological study grounded in social constructionist epistemology, bereaved parent/caregivers completed a semi-structured interview about their legacy perceptions and experiences. The interviews were audio-recorded, transcribed, and analyzed using an inductive, open coding approach grounded in psychological phenomenology.

Setting/participants:

Participants were parents/caregivers and one adult sibling of children (ages 6 months–18 years) that died between 2000 and 2018 at a children’s hospital in the Southeastern United States and spoke English as their primary language.

Results:

Sixteen parents/caregivers and one adult sibling were interviewed. Participants’ responses converged across three themes: (1) definitions of legacy, including traits and characteristics, impacts on others, and the child’s enduring presence; (2) manifestations of legacy, such as tangible items, experiences, traditions, and rituals, and altruism; and (3) factors perceived to affect legacy experiences, including characteristics of the child’s death and one’s personal grief process.

Conclusion:

Bereaved parents/caregivers define and experience their child’s legacy in ways and manifestations that conflict with current legacy building interventions used in pediatric healthcare settings. Thus, an immediate shift from standardized legacy-oriented care to individualized assessment and intervention is needed to provide high-quality patient- and family-centered pediatric palliative care.
Validating a Physics-Based Automatic Classification Scheme for Impact Echo Signals on Data Using a Concrete Slab with Known Defects
Authors: Sengupta Agnimitra , Azari Hoda , Guler S. Ilgin , Shokouhi Parisa
Published: June 2023

Impact echo (IE) is capable of locating subsurface defects in concrete slabs from the vibrational response of the slab to a mechanical impact. For an intact slab (“good” condition), the frequency spectrum of the IE is dominated by a single peak corresponding to the slab’s “thickness resonance frequency,” whereas the presence of subsurface defects (“fair” or “poor” conditions) could manifest in various ways such as multiple distinct peaks at frequencies higher, or lower, than the thickness resonance. In previous research, the authors have proposed a frequency partitioning of the spectrum for IE signal classification. Firstly, the thickness resonance frequency band is identified using a data-driven approach and then the IE signals are represented by their energy distribution in three bands—frequencies less than, within, and greater than the thickness resonance. Following this feature extraction, an unsupervised clustering approach is used to identify the centroids for each signal class—good, fair, and poor—which are further used to classify any test signal into one of the three aforementioned classes. The classification is developed by training on unlabeled IE signals from real bridge deck data (the Federal Highway Administration’s [FHWA’s] InfoBridge dataset) without making use of any labeled data. This study aims to validate the proposed methodology on a labeled dataset of eight reinforced concrete specimens constructed at the FHWA Advanced Sensing Technology Nondestructive Evaluation laboratory having known artificial defects. Our findings indicate that the physics-based feature definition and the method developed on real bridge data are robust and can classify IE signals in the labeled data with moderate accuracy.
“The Real is Relational”: An Epistemological Analysis of Pierre Bourdieu's Generative Structuralism
Authors: Vandenberghe Frédéric
Published: June 2023

An internal reconstruction and an immanent critique of Bourdieu's generative structuralism is presented. Rather than starting with the concept of “habitus,” as is usually done, the article tries to systematically reconstruct Bourdieu's theory by an analysis of the relational logic that permeates his whole work Tracing the debt Bourdieu's approach owes to Bachelard's rationalism and Cassirer's relationalism, the article examines Bourdieu's epistemological writings of the 1960s and 70s. It tries to make the case that Bourdieu's sociological metascience represents a rationalist version of Bhaskar's critical realism, and enjoins Bourdieu to give heed to the realist turn in the philosophy of the natural and the social sciences. The article shows how Bourdieu's epistemological assumptions are reflected in his primary theoretical constructs of “habitus” and “field.” To concretize their discussion, it analyzes Bourdieu's reinterpretation of Weber in his theory of the field of religion and of the young Mannheim in his theory of the scientific field.

Dr. Schuler is working with colleagues toward developing an understanding of how nursing experiences inform their role development. In this scholarly dialogue, Dr. Schuler shares her path to nursing scholarship and her recent contributions to nursing knowledge development.
Middle-Range Theory of the Adapting Foster Family: Mathematical Modeling in Nursing Science
Authors: Platt Christine , Gephart Sheila , Platt Brennan
Published: June 2023

Nursing science has the epistemic advantage of using nursing practice for developing middle-range theories to bridge abstract ideas with clinical research. The theory of the adapting foster family draws upon extant theories of both family systems theory and transition theory while integrating experiences from nursing practice. The new theory provides a framework for improving outcomes for children in foster care through greater placement stability. Theory development incorporated a literature review, concept exploration, statement synthesis, and mathematical theory modeling to elucidate the interaction between concepts and provide insight to the unique fostering experience.

Pursuing Money and Power, Prosocial Contributions, or Personal Growth: Measurement and Nomological Net of Different Career Strivings
Authors: Hirschi Andreas , Pang Dandan
Published: June 2023

There is considerable agreement that individuals need an “inner compass” to manage their careers as self-directed and values-driven. However, how different career strivings (i.e., long-term, values-related career goals) affect career development remains largely unaddressed. To tackle this issue, we conducted a study to develop and validate new scales to assess self-enhancement, self-transcendence, and personal growth career strivings, representing key self-focused and other-focused extrinsic and intrinsic career goals. The validation of the scales among 389 U.S. and 490 German workers confirmed that career strivings are differentially related to existing measures of intrinsic and extrinsic career goals, work values, and motivational work strivings. Moreover, we confirmed with a time-lagged study among 354 German workers that career strivings (especially personal growth strivings) relate positively to career commitment, career satisfaction, and life meaningfulness. The studies support the utility of examining different career strivings as critical motivational factors in self-directed career management in future research.
When Online Reputation Drives Consumers’ Online Repurchase Intentions: An Egyptian Story
Authors: Shamma Hamed M. , El Masry Radwa , Dutot Vincent
Published: June 2023

The aim of this article is to understand how e-reputation can be a positive predictor of online repurchase intentions. Building on the Hierarchy-of-Effects model and the scale of e-reputation developed by Dutot and Castellano (2015 , Corporate Reputation Review 18(4), 294–313), the study is applied and validated in an Egyptian context. Following a quantitative approach, data were collected through an online survey and tests were performed following a structural equation modelling approach (SmartPLS software). The results indicate that 57.9% of the online repurchase decision is dependent upon e-reputation. Three of the four e-reputation dimensions are validated in the Egyptian context, with interesting differences based on age and gender. Practical and academic implications are identified that can help managers and academicians study e-reputation and understand how to enhance their consumers repurchase intentions. The approach is driven by the goal of helping firms understand how they could build and maintain strong e-reputations to sell more. This study (1) proposes new predictors of online repurchase intentions, (2) validates an e-reputation management scale and (3) examines its effect on online repurchase intentions. Moreover, it supports the idea that gender-oriented strategies should be designed.
Fault classification using convolutional neural networks and color channels for time-frequency analysis of acoustic emissions
Authors: Nashed Mohamad S , Renno Jamil , Mohamed M Shadi
Published: June 2023

We present a novel method for real-time fault classification using the time history of acoustic emissions (AEs) recorded from a lab-scale gas turbine operating under normal and faulty conditions across multiple turbine speeds. Time-frequency features are extracted using the continuous wavelet transform, and for each signal, the root mean square (RMS) and kurtosis are calculated. We employ a color mapping technique to combine the time-frequency and statistical features into a single red–green–blue (RGB) image. The red channel is mapped to the time-frequency data, whereas the green and blue channels are mapped to the RMS and kurtosis, respectively. Subsequently, a deep convolutional neural network is trained on the generated images to classify the gas turbine condition. We show that the proposed model can form an online monitoring system using AEs to classify multiple running conditions at various turbine speeds. The methodology not only achieves real-time classification of faults but also minimizes the human intervention in identifying these faults. The datasets and codes used in this paper will be openly available.
Gemcitabine-associated digital necrosis in metastatic breast cancer
Authors: Türkel Alper , Özdemir Mustafa , Kurtuluş Aziz , Doğan Mutlu
Published: June 2023

Introduction

Gemcitabine is a nucleoside analog antimetabolite used in various malignancies, including metastatic breast cancer. Objective response rates in its use as a single agent in the treatment of metastatic breast cancer are not to be underestimated. Cutaneous, hematological, pulmonary, and vascular side effects are well-known side effects. Venous thromboembolism may occur with antineoplastics, such as platinum compounds. Arterial thromboembolism is rare in cancer, almost rare with chemotherapy. Here, we present a metastatic breast cancer patient who had digital necrosis due to arterial occlusion with gemcitabine monotherapy.

Case report

A 54-year-old metastatic breast cancer female patient had digital ischemia and necrosis in the left hand's fifth finger after the second course of single-agent gemcitabine as the fourth line setting. Gemcitabine was discontinued, and medical treatment was started. Thrombus was detected in the left subclavian artery digital angiography. Balloon angioplasty and stenting were applied. However, digital amputation had to be performed since tissue necrosis had not regressed despite radiological interventions and medical treatment.

Management and outcome

Gemcitabine was discontinued. Low molecular weight heparin and acetylsalicylic acid were started. The distal phalanx was amputated due to necrosis during follow-up. Gemcitabine was permanently stopped.

Discussion

Gemcitabine-related vascular events, including arterial thrombosis, may also occur in cancer patients, especially those with higher tumor burden. Therefore, predisposing factors for hypercoagulability and vascular occlusion should be questioned in more detail even before starting antineoplastics which are known to have a lower risk for thrombosis, such as gemcitabine monotherapy.

Authors: Hsin Chun-Hsien , Yang Hsuan-Tzu , Feng Pin-Chao , Su Ta-Wei , Yu Sheng-Yueh , Ko Po-Jen
Published: June 2023

Objective:

To report the efficacy and safety of a drug-coated balloon (Ranger, Boston Scientific) in patients with dysfunctional autogenous arteriovenous fistula.

Methods:

In this investigator-initiated, prospective observational cohort study, 25 participants with dysfunctional arteriovenous fistula were enrolled from January 2018 to June 2019. The drug-coated balloon was applied after successful vessel preparation by high-pressure balloon angioplasty. The primary endpoint was the target lesion primary patency rate at 6 months. The secondary outcome included anatomical and clinical success rate, postoperative major adverse events within 30 days, and the target lesion primary patency rate at 12 months. Statistical analysis of the data was performed. The χ test or Fisher’s exact test was used for analyzing categorical variables, and continuous variables were analyzed using Student’s t-test. Also, Kaplan-Meier analysis was used to evaluate the target lesion primary patency days with the log-rank test.

Results:

At 6 months, the target lesion primary patency rate was 68% in the drug-coated balloon treatment group. The anatomical and clinical success rates were 100%. One patient had thrombosed access 10 days after the index procedure, and two died of cardiovascular events 4 months after the operation. Subgroup analysis showed that the early recurrent stenosis group had non-inferior mean drug-coated balloon primary patency days (less than 90 days after prior percutaneous angioplasty, n = 10) compared with the late recurrence group (prior PTA patency days more than 90 days, n = 10), 179.3 ± 102.9 versus 257.1 ± 71 days ( p = 0.153). DCB angioplasty had significant improvement in primary patency days for early recurrent stenosis (67.7 ± 19.3 vs 179.3 ± 102.9, p < 0.001).

Conclusions:

The results demonstrated the appliance of Ranger DCB in stenotic AVFs is a safe and effective treatment modality, especially for early recurrent AVF stenosis.

An indoor location-based hospital porter management system and trace analysis
Authors: Lee Chia-Rong , Chu Edward T.-H. , Shen Hong-Cheng , Hsu Juin , Wu Hui-Mei
Published: June 2023

Porters play an important role in supporting hospital operations. Their responsibilities include transporting patients and medical equipment between wards and departments. They also need to deliver specimens, drugs, and patients’ notes to the correct place at the right time. Therefore, maintaining a trustworthy and reliable porter team is crucial for hospitals to ensure the quality of patient care and smooth the flow of daily operations. However, most existing porter systems lack detailed information about the porter movement process. For example, the location of porters is not transparent to the dispatch center. Thus, the dispatcher does not know if porters are spending all their time providing services. The invisibility makes it difficult for hospitals to assess and improve the efficiency of porter operations. In this work, we first developed an indoor location-based porter management system (LOPS) on top of the infrastructure of indoor positioning services in the hospital National Taiwan University Hospital YunLin Branch. The LOPS provides real-time location information of porters for the dispatcher to prioritize tasks and manage assignments. We then conducted a 5-month field trial to collect porters’ traces. Finally, a series of quantitative analyses were performed to assess the efficiency of porter operations, such as the movement distribution of porters in different time periods and areas, workload distribution among porters, and possible bottlenecks of delivering services. Based on the analysis results, recommendations were given to improve the efficiency of the porter team.
“‘You cannot come to this country’—that's what the government says sometimes, when you’re Brown”: African American children's critical literacies and emergent solidarity
Authors: Johnson Wintre Foxworth
Published: June 2023

Decades of research demonstrate that young children make meaning about race and racism. Yet there remains a dearth of scholarship about whether and how African American children are thinking across racial and ethnic difference to make sense of systemic inequities. Moreover, there are but a handful of scholars who have documented the ways that children and youth engage in acts of solidarity. Extending the growing body of literature that privileges young children of color's critical perspectives, this article examines African American first-graders’ sociopolitical awareness; in particular, it explores how they expressed their understanding that racial discrimination undergirded contemporary US immigration policies. These data reveal that the children possessed a capacity for demonstrating solidarity with other non-white people, in that they named and critiqued the marginalization experienced by immigrant communities of color. Drawing on Black feminist epistemologies, critical literacy, and critical consciousness, the author argues that the children's emergent solidarity can be understood through their three rhetorical moves: (1) interchanging Black and Brown people in name; (2) advancing a critical moral ideal by juxtaposing current and former political leaders; and (3) invoking knowledge of US history. Although popular media and political discourse seldom portray immigration as an issue that concerns Black communities in the US, African Americans have long understood that their own liberation is connected to that of other marginalized groups. As such, this article urges early childhood researchers to examine the nature of the questions being asked about young African American children's racial meaning-making practices and knowledges about belonging, equity, and inclusion within and outside schools.
Outcomes of Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB) Procedure for the Treatment of Extensive Aortoiliac Occlusive Disease Using the BeGraft Balloon-Expandable Covered Stent: A Multicenter Observational Study

Published: June 2023

Purpose:

The covered endovascular reconstruction of the aortic bifurcation (CERAB) technique offers an alternative for Trans-Atlantic Inter-Society Consensus (TASC) C/D lesions involving the aortic bifurcation. The study aims to evaluate the outcomes of the CERAB technique for extensive aortoiliac occlusive disease (AIOD) using the BeGraft balloon-expandable covered stent (BECS).

Materials and Methods:

This is a physician-initiated, multicenter, retrospective, observational study. Between June 2017 and June 2021, all consecutive patients who underwent the CERAB procedure using the BeGraft stent (Bentley InnoMed, Hechingen, Germany) in 3 clinics were enrolled. Patients’ demographics, lesion characteristics, and procedural results were collected and retrospectively analyzed. Follow-up was done at 1, 6, and 12 months and then annually with clinical examination, ankle-brachial index (ABI), and duplex ultrasound. The primary endpoint was the patency at 12 months. Secondary endpoints included procedural-related complications, secondary patency, freedom from target lesion revascularization (TLR), and clinical improvement.

Results:

In all, 120 patients (64 men) with a median age of 65 years (range: 34–84 years) were analyzed. Most patients had extensive AIOD classified as TASC II C (n=32; 26.7%) or TASC II D (n=81; 67.5%). The median duration of the procedure was 120 minutes (interquartile range [IQR]: 80–180 minutes). All 454 BeGraft stents (137 aortic and 317 peripheral) were successfully delivered and deployed. The overall procedural complication rate was 14 (11.7%). The median hospital length of stay was 5 days (IQR: 3–6 days). All patients improved clinically, and the ABI increased significantly (p<0.05). The median follow-up was 19 months (range: 6–56 months). The primary patency rate, secondary patency rate, and freedom from TLR at 12 months were 94.5%, 97.3%, and 93.5%, respectively.

Conclusions:

The CERAB procedure with BeGraft BECSs has a high technical success rate, favorable patency outcomes, and low morbidity, even in relatively ill patients with extensive AIOD. Prospective randomized studies on the CERAB technique are definitely recommended.

Clinical Impact

This study evaluates the outcomes of BeGraft stents used during the covered endovascular reconstruction of the aortic bifurcation (CERAB) procedure. To date, several balloon-expandable covered stents have been used for this technique with satisfactory results. This study showed the safety and excellent patency of the CERAB technique in extensive AIOD using BeGraft balloon-expandable covered stents.
Reevaluating Sleep Quality During COVID-19 and Associations With Quarantine, Mental Health, Stress, and Screen Time in Young Adults: Results From a Cross-Sectional Online Survey
Authors: Wiciak Michelle Teresa , Shazley Omar , Santhosh Daphne
Published: June 2023

The COVID-19 pandemic affected individual sleep quality, especially with high-stress levels. We assessed sleep quality in young adults during COVID-19, and mental health, stress, and screen time (ST) use. An international cross-sectional study was conducted from September 2020 to January 2021. The surveys assessed sleep quality (PSQI), ST use, and mental health. 183 participants were eligible for analysis. The average global PSQI score was 7.29 (sd = 3.58, n = 99). Associations were found between global PSQI scores and Fear of COVID-19 (r (98) = .223, P = .027), anxiety scores (r (99) = -.541, P < .001), increased total stress scores (r (88) = .486, P < .001), and depression (r (97) = .628, P < .001). Those currently quarantining had statistically higher PSQI scores than those who quarantined in the past (F (2,175) = 3.397, P = .036), but not for those who did not quarantine. Differences were found between genders for global PSQI (F (4,94) = 2.865, P < .027) and poor vs good sleep (X2 (1,98) = 3.982, P = .046). There was also a relationship between ethnicity and poor vs good sleep quality (X2 (2,94) = 6.538, P = .038). We did not find associations between ST and sleep quality but found poor sleep quality significantly related to mental health during COVID-19. We found no direct evidence that quarantining itself results in poor sleep quality. Interventions need to maximize sleep quality in certain groups, like females and ethnic minorities.
Utilizing the supreme anterior connecting artery in embolization of a parietal lobe arteriovenous malformation
Authors: Ishigami Daiichiro , Ota Takahiro , Dofuku Shogo
Published: June 2023

Background

The supreme anterior connecting artery (SAConnA) is an exceedingly rare anatomical variant. This artery may interconnect bilateral anterior cerebral arteries (ACAs), yet its existence and clinical implications are scarcely discussed in the literature.

Case description

A 60-year-old man with no significant past medical or family history presented to our emergency department. He exhibited right homonymous hemianopsia and Gerstmann's syndrome. Cranial computed tomography indicated a left parietal lobar hemorrhage, and digital subtraction angiography revealed a flow-related aneurysm in the anterior communicating artery, with the arteriovenous malformation (AVM) receiving blood supply from the anterior, middle, and posterior cerebral arteries. Notably, the angiography also disclosed the presence of a SAConnA. We adopted a treatment approach of staged embolizations followed by resection. During the second session, the SAConnA was utilized for the embolization of feeding arteries within the ACA system.

Conclusions

This case demonstrates that SAConnA can be associated with AVMs and can serve as an access route during AVM embolization. SAConnA may be a remnant artery interconnecting bilateral ACAs formed during early embryogenesis.
Perceiving others’ cognitive effort through movement: Path length, speed, and time
Authors: Székely Marcell , Michael John
Published: June 2023

Effort perception is a crucial capacity underpinning characteristically human forms of sociality, allowing us to learn about others’ mental states and about the value of opportunities afforded by our environment, and supporting our ability to cooperate efficiently and fairly. Despite the crucial importance and prevalence of effort perception, little is known about the mechanisms underpinning it. Across two online experiments ( N = 462), we tested whether adults estimate others’ cognitive effort costs by tracking perceptible properties of movement such as path length, time, and speed. The results showed that only time had a consistent effect on effort perception, that is, participants rated longer time as more effortful. Taken together, our results suggest that within the context of our task—observing an agent deciphering a captcha—people rely on the time of others’ actions to estimate their cognitive effort costs.
Modes of failure following locking plate fixation of the distal radius: a thematic analysis of 517 fractures
Authors: Newton Ashley , Julian Harriet , Theodoraki Mona , Redfern James , Cheung Graham , Brown Daniel
Published: June 2023

Anterior locking plate fixation of the distal radius is a common procedure with reliable results. Failure of fixation is sometimes seen. The aim of the present study was to identify the reasons for failure. In total, 517 cases met the study inclusion criteria. Of them, 23 cases had failure of fixation (4.4%). Failure analysis generated qualitative data. Subsequent thematic analysis identified the primary mode of failure and contributing factors. Primary modes were identified as failure to support all key fracture fragments ( n = 20), wrong choice of implant ( n = 1), failure of union ( n = 1) and poor bone quality ( n = 1). Contributing factors were errors in plate positioning, fracture reduction, implant selection and screw configuration, as well as fracture pattern complexity and poor bone quality. Most failed fixations had a primary mode and two or three contributing factors. Overall anterior plating is reliable with a low rate of surgical failure. Knowledge of failure modes will aid operative planning and prevent failure.

Published: June 2023

State-level school nursing infrastructure supports are essential for building equitable, evidence-based, quality school nursing services. Two recently published instruments, the State School Health Infrastructure Measure (SSHIM) and the Health Services Assessment Tool for Schools (HATS), provide opportunities to assess the extent of state-level infrastructure supports for school nursing and school health services. These instruments can be useful for planning and prioritizing to address needs to improve system-level quality and equity in school health services for the preK–12 population in each state.
Cross-cultural adaptation and validation of the Bangla version of the Psoriasis Disability Index
Authors: Nishat Farhana , Bhuiyan Mohammed Saiful Islam , Khan Md. Alauddin , Jesmin Afroza , Khan Md. Abdullah Saeed , Hasan Mohammad Jahid
Published: June 2023

Background:

The Psoriasis Disability Index (PDI) is used for the quality-of-life assessment of psoriasis patients. However, a locally adapted Bangla version of the PDI ( B-PDI) instrument is currently lacking in Bangladesh. To translate the instrument, adapt, and validate it among psoriatic patients of the country was the objective of the study.

Methods:

Translation, adaptation, and back-to-back translation to Bangla were made from the original English PDI. The final Bangla instrument was applied among 83 psoriasis patients twice at 10 days intervals. The psychometric property of the instrument was evaluated. Item-level content-validity index (CVI) was used to check the content validity of the instrument. Convergent validity was tested by comparing the B-PDI with the validated Bangla version of Short Form 36(SF-36) and the Psoriasis Area Disability Index (PASI) score. Necessary testing was used to assess internal consistency and test-retest reliability.

Result:

The B-PDI was well-accepted by the patients. It showed good internal consistency (Cronbach’s alpha = 0.76) and very high test-retest reliability (Pearson r = 0.92, p < 0.001). The scale demonstrated excellent content validity (Content Valid Index [CVI] = 1). The instrument had satisfactory convergent validity with four components of SF-36. Pearson correlation coefficient for physical, emotional, social, and pain domains of SF-36 was 0.663, 0.644, 0.808, and 0.862, respectively, and for PASI score was 0.812.

Simple Correlations for Thickness Profiles in Melt Casting
Authors: Lightfoot Edwin J
Published: June 2023

Neck-in during melt casting of polymeric film and extrusion coating along with the related issue of edge bead formation, has been widely studied. However, one aspect of this problem that has received relatively little attention is empirical correlations for the thickness profile near the edges of the sheet. The correlations given here may prove useful for industrial operations as well as provide benchmarks for numerical studies of the myriad factors that influence neck-in.

Background

Oxides of lanthanide rare-earth elements show great potential in the fields of imaging and therapeutics due to their unique electrical, optical and magnetic properties. Oxides of lanthanide-based nanoparticles enable high-resolution imaging of biological tissues by magnetic resonance imaging (MRI), computed tomography (CT) imaging, and fluorescence imaging. In addition, they can be used to detect, treat, and regulate diseases by fine-tuning their structure and function. It remains challenging to achieve safer, efficient, and more sensitive nanoparticles for clinical applications through the structural design of functional and nanostructured rare-earth materials.

Result

In this study, we designed a mesoporous silica-coated core–shell structure of europium oxide ions to obtain near-infrared two-photon excitation fluorescence while maintaining high contrast and resolution in MRI. We designed enhanced 800 nm photoexcitation nanostructures, which were simulated by the finite-difference method (FDM) and finite-difference time-domain method (FDTD). The nanoparticle structure, two-photon absorption, up-conversion fluorescence, magnetic properties, cytotoxicity, and MRI were investigated in vivo and in vitro. The nanoparticle has an extremely strong optical fluorescence response and multiple excitation peaks in the visible light band under the 405 nm continuous-wave laser excitation. The nanoparticle was found to possess typical optical nonlinearity induced by two-photon absorption by ultrafast laser Z-scan technique. Two-photon excited fluorescence of visible red light at wavelengths of 615 nm and 701 nm, respectively, under excitation of the more biocompatible near-infrared (pulsed laser at 800 nm). In an in vitro MRI study, a T1 relaxation rate of 6.24 mM−1 s−1 was observed. MRI in vivo showed that the nanoparticles could significantly enhance the signal intensity in liver tissue.

Conclusions

These results suggest that this sample has applied potential in visible light fluorescence imaging and MRI.
Measuring bereavement prevalence in a complex sampling survey: the 2019 Georgia Behavioral Risk Factor Surveillance System (BRFSS)

Published: June 2023

Background

The Behavioral Risk Factor Surveillance System (BRFSS) is an annual survey designed to identify trends in the public’s health. In its 2019 field survey, the U.S. state of GA tested a new 3 – item module to measure the numbers of bereaved, resident adults aged 18 years and older. Participants were eligible if they answered ‘Yes’ to the item ‘Have you experienced the death of a family member or close friend in the years 2018 or 2019?’. This analysis explores two research questions. Can estimates for bereavement prevalence be derived without large sampling errors, low precision, and small subsamples? Can multiple imputation techniques be applied to overcome non-response and missing data to support multivariate modeling?

Methods

BRFSS is a non-institutionalized sample of adults aged 18 years and older living in the U.S. state of Georgia. Analyses in this study were conducted under two scenarios. Scenario 1 applies the complex sample weights created by the Centers for Disease Control and imputes values for missing responses. Scenario 2 treats the data as a panel – no weighting combined with removal of persons with missing data. Scenario 1 reflects the use of BRFSS data for public health and policy, while Scenario 2 reflects data as it is commonly used in social science research studies.

Results

The bereavement screening item has a response rate (RR) of 69.1% (5206 of 7534 persons). Demographic subgroups and categories of health have RR of 55% or more. Under Scenario 1, the estimated prevalence of bereavement is 45.38%, meaning that 3,739,120 adults reported bereaved in 2018 or 2019. The estimated prevalence is 46.02% with Scenario 2 which removes persons with any missing data (4,289 persons). Scenario 2 overestimates the bereavement prevalence by 1.39%. An illustrative logistic model is presented to show the performance of exposure to bereavement under the two data scenarios.

Conclusions

Recent bereavement can be ascertained in a surveillance survey accounting for biases in response. Estimating bereavement prevalence is needed for measuring population health. This survey is limited to one US state in a single year and excludes persons aged 17 years and younger.

Published: June 2023

Background

We aimed to address the shortage of evidence regarding the safety of the local resection approach by comparing long-term oncological outcomes between patients managed by local resection and those who underwent radical resection.

Methods

This was a propensity-score matched cohort analysis study that included patients of all ages diagnosed with locally advanced rectal cancer (LARC) who had received neoadjuvant chemoradiotherapy (nCRT) at the Fujian Medical University Union Hospital and Fujian Medical University Affiliated Zhangzhou Hospital, China, between Jan 10, 2011, to Dec 28, 2021. Partial patients with a significant downstage of the tumor were offered management with the local resection approach, and most of the rest were offered radical resection if eligible.

Findings

One thousand six hundred ninety-three patients underwent radical resection after nCRT, and another 60 patients performed local resection. The median follow-up times were 44.0 months (interquartile range = 4–107 months). After propensity-core matching (PSM), in the Kaplan–Meier curves, local resection (n = 56) or radical resection (n = 211) was not significantly associated with 1-, 3-, and 5-year cumulative incidence of overall survival (OS) (HR = 1.103, 95% CI: 0.372 ~ 3.266), disease-free survival (DFS) ((HR = 0.972, 95% CI: 0.401 ~ 2.359), local recurrence (HR = 1.044, 95% CI: 0.225 ~ 4.847), and distant metastasis (HR = 0.818, 95% CI: 0.280 ~ 2.387) (all log-rank P > 0.05). Similarly, multivariate Cox regression analysis indicates that local excision still was not an independent risk factor for OS (HR = 0.863, 95% CI: 0.267 ~ 2.785, P = 0.805) and DFS (HR = 0.885, 95% CI: 0.353 ~ 2.215, p = 0.794).

Conclusion

Local resection can be a management option in selected patients with middle-low rectal cancer after nCRT for LARC and without loss of oncological safety at five years.

Published: June 2023

Objective

To construct a survival prediction model for patients with TNM stage III hepatocellular carcinoma (HCC) to guide the clinical diagnosis and treatment of HCC patients and improve prognosis.

Methods

Based on data from patients with stage III (AJCC 7th TNM stage) recorded by the American Institute of Cancer Research from 2010 to 2013, risk factors affecting the prognosis were screened by Cox univariate and multivariate regression, line plots was constructed, and the credibility of the model was verified by Boostrap method. ROC operating curves, calibration curves and DCA clinical decision curves were used to evaluate the model, and Kaplan–Meier was used for survival analysis was used to evaluate the efficacy of the model. External survival data from patients newly diagnosed with stage III hepatocellular carcinoma during 2014–2015 were used to validate and fit the model and to optimize the model.

Results

Age > 75 years vs.18-53 years [HR = 1.502; 95%CI(1.134–1.990)], stage IIIC vs. Stage IIIA [HR = 1.930; 95%CI(1.509–2.470)], lobotomy vs. non-surgery [HR = 0.295; 95%CI(0.228–0.383)], radiotherapy vs. non-radiotherapy [HR = 0.481; 95%CI(0.373–0.619)], chemotherapy vs. Non-chemotherapy [HR = 0.443; 95%CI(0.381–0.515)], positive serum AFP before treatment vs. negative [HR = 1.667; 95%CI(1.356–2.049)], the above indicators are independent prognostic factors for patients with stage III hepatocellular carcinoma, and the P values for the above results were less than 0.05. A joint prediction model was constructed based on age, TNM stage, whether and how to operate, whether to receive radiotherapy, whether to receive chemotherapy, pre-treatment serum AFP status and liver fibrosis score. The consistency index of the improved prognosis model was 0.725.

Conclusions

The traditional TNM staging has limitations for clinical diagnosis and treatment, while the Nomogram model modified by TNM staging has good predictive efficacy and clinical significance.
