Authors: Velmishi Virtut , Alushani Dritan , Dervishi Ermira , Heta Saimir , Sila Spiro , Cullufi Paskal
Published: May 2024

Background. Duodenal atresia or stenosis are different degrees of the same abnormality. They usually occur at the level of the ampulla of Vater and are thought to be an embryologic defect during the development of the foregut, leading to abnormal recanalization. Complete duodenal atresia is usually symptomatic in the early neonatal period, while partial obstruction (web, stenosis) may have a late presentation and a more challenging diagnosis such as in our case. Case Presentation. The patient, a 16-year-old girl, presented with abdominal pain, recurrent vomiting, and growth failure. An upper GI study with barium showed an image compatible with gastroptosis. Further diagnostic procedures confirmed a rare finding such as congenital duodenal stenosis. She underwent surgical intervention, and the recovery period was uneventful. Conclusion. Gastroptosis is not diagnostic for a particular disease. This rare radiological finding in children may obscure uncommon diagnosis, such as congenital duodenal stenosis, which can present a diagnostic challenge beyond early childhood.

Published: May 2024

Vegan leather derived from mushroom mycelium is a revolutionary technology that addresses the issues raised by bovine and synthetic leather. Jute–mycelium-based vegan leather was constructed using hessian jute fabric, natural rubber solution, and extracted polyhydroxyalkanoate (PHA) biopolymer from Bacillus subtilis strain FPP-K isolated from fermented herbal black tea liquor waste. The bacterial strain was confirmed using 16S rRNA genomic sequencing. The structural characteristics of sustainable mycelium vegan leather were identified using FTIR, SEM, and TGA methods. To address the functional features of the developed vegan leather, solubility, swelling degree, WVP, WCA, and mechanical strength were also evaluated. Mycelium networking was further validated by micromorphological examination (SEM) of the leather sample’s cross-sectional area. Jute–mycelium leather demonstrated a tensile strength of 8.62 MPa and a % elongation of 8.34, which were significantly greater than the control sample. Vegan leather displayed a strong peak in the O ═ H group of carbohydrates in the examination of chemical bonds. A high-frequency infrared wavelength of 1,462 cm−1 revealed the amide group of protein due to the presence of mycelium, while the absorption peak at 1,703 cm−1 in leather indicated the crosslinking of PHA. Moreover, the TGA study finalized the thermal stability of leather. The enhanced hydrophobicity and reduced swelling degree and solubility also endorsed the water resistance properties of the leather. The results of the investigation substantiated the potential properties of mycelium vegan leather as animal- and environment-free leather.
The Significance of Stochastic CTMC Over Deterministic Model in Understanding the Dynamics of Lymphatic Filariasis With Asymptomatic Carriers
Authors: Stephano Mussa A. , Irunde Jacob I. , Mayengo Maranya M. , Kuznetsov Dmitry
Published: May 2024

Lymphatic filariasis is a leading cause of chronic and irreversible damage to human immunity. This paper presents deterministic and continuous‐time Markov chain (CTMC) stochastic models regarding lymphatic filariasis dynamics. To account for randomness and uncertainties in dynamics, the CTMC model was formulated based on deterministic model possible events. A deterministic model’s outputs suggest that disease extinction is feasible when the secondary threshold infection number is below one, while persistence becomes likely when the opposite holds true. Furthermore, the significant contribution of asymptomatic carriers was identified. Results indicate that persistence is more likely to occur when the infection results from asymptomatic, acutely infected, or infectious mosquitoes. Consequently, the CTMC stochastic model is essential in capturing variabilities, randomness, associated probabilities, and validity across different scales, whereas oversimplification and unpredictability of inherent may not be featured in a deterministic model.

Published: May 2024

Long‐term diabetes often leads to chronic wounds refractory to treatment. Cell‐based therapies are actively investigated to enhance cutaneous healing. Various cell types are available to produce biological dressings, such as adipose‐derived stem/stromal cells (ASCs), an attractive cell source considering their abundancy, accessibility, and therapeutic secretome. In this study, we produced human ASC‐based dressings under a serum‐free culture system using the self‐assembly approach of tissue engineering. The dressings were applied every 4 days to full‐thickness 8‐mm splinted skin wounds created on the back of polygenic diabetic NONcNZO10/LtJ mice and streptozotocin‐induced diabetic K14‐H2B‐GFP mice. Global wound closure kinetics evaluated macroscopically showed accelerated wound closure in both murine models, especially for NONcNZO10/LtJ; the treated group reaching 98.7% ± 2.3% global closure compared to 76.4% ± 11.8% for the untreated group on day 20 (p= 0.0002). Histological analyses revealed that treated wounds exhibited healed skin of better quality with a well‐differentiated epidermis and a more organized, homogeneous, and 1.6‐fold thicker granulation tissue. Neovascularization, assessed by CD31 labeling, was 2.5‐fold higher for the NONcNZO10/LtJ treated wounds. We thus describe the beneficial impact on wound healing of biologically active ASC‐based dressings produced under an entirely serum‐free production system facilitating clinical translation.
Displacement Mechanism and Flow Characteristics of Polymer Particle Dispersion System Based on Capillary Bundle Model
Authors: Sui Yingfei , Cui Chuanzhi , Wang Yidan , Lu Shuiqingshan , Qian Yin
Published: May 2024

During the development of oil reservoirs, a rapid increase in water cut following reservoir flooding leads to inefficient or ineffective circulation of injected water, rendering a significant portion of the remaining oil in the reservoir inaccessible. The displacement method using polymer particle dispersion systems effectively solves the issue of rapid water breakthrough in oil reservoirs. Owing to the particle phase separation phenomenon, polymer particles can selectively penetrate into the larger pores where water circulation is inefficient, enhance their flow resistance, and thereby achieve equilibrium displacement along with an increased swept volume. This paper investigates the heterogeneous distribution of polymer particles within a porous medium, incorporates the red blood cell dendrite concentration distribution theory from biological fluid mechanics, and develops a mathematical model to delineate the viscosity characteristics of polymer particle dispersion systems, taking into account the phase separation phenomenon. Building on this foundation, it formulates a capillary bundle model for the polymer particle dispersion system specifically designed for oil displacement and proceeds to determine its relative permeability curve. Simulation outcomes reveal that at a water saturation level of 0.063, the concentration of polymer particles in fractured large pore capillaries is markedly elevated, yet capillaries with a pore size under 26 μm remain devoid of polymer particles. With the increase of water saturation, the concentration of polymer particles in large pore capillaries reduces, whereas it progressively augments in medium pore capillaries. Upon reaching a peak water saturation of 0.751, capillaries smaller than 18 μm are entirely free of polymer particles. These findings suggest that the heterogeneous distribution of polymer particles markedly inhibits the percolation capabilities of the dispersed system following a water phase breakthrough, facilitating the entry of more dispersion into oil‐laden capillaries and thus enhancing the flow capacity of the oil phase.

Published: May 2024

The efficacy of therapeutics for acute promyelocytic leukemia (APL) has exhibited an increase in recent years. Only a few patients experience relapse, including extramedullary relapse, and in patients with extramedullary relapse, the central nervous system (CNS) is the most common site. To date, there is no expert consensus or clinical guidelines available for CNS relapse, at least to the best of our knowledge. The optimal therapeutic strategy and management options for these patients remain unclear. The present study reports the treatment of a patient with APL with multiple isolated relapses in the CNS. In addition, through a mini-review of the literature, the present study provides a summary of various reports of this disease and discusses possible treatment options for these patients.

Published: May 2024

Energy storage systems (ESS) are seeing rapid market growth due to the changing worldwide landscape of electricity distribution and consumption. An ESS must possess the capability to oversee the functioning of the system’s modules under abnormal circumstances, while also having the ability to supervise, manage, and optimize the performance of one or more battery modules. At present, the condition of batteries is assessed based on two factors: the level of charge (SOC) and the overall condition (SOH). By using these two characteristics, it becomes feasible to compute the anticipated battery lifespan and evaluate a battery’s efficiency. The assessment of SOH is a crucial determinant in guaranteeing the effectiveness, dependability, and security of batteries in electric vehicles (EVs). Nevertheless, the safety issues resulting from the imprecise estimation and forecasting of battery health status have garnered significant attention in academic circles. This study presents a comprehensive evaluation of several SOH monitoring techniques. In order to achieve this objective, various scientific and technical literatures are examined and the corresponding methodologies are categorized into distinct groupings. The groupings are categorized based on the manner in which the procedure is executed: methods and techniques used in experiments and models. This paper provides a comprehensive overview of the benefits and drawbacks of several SOH assessment and prediction techniques, along with the associated obstacles in SOH estimation.

Published: May 2024

Yogurt consumption is a significant factor in reducing the risk of hypertension and preventing cardiovascular diseases. Although increasing evidence has emerged regarding the potential benefits of probiotics in hypertension, there is a lack of large, cross-sectional studies assessing the association between yogurt intake and blood pressure parameters. We aimed to evaluate the association between yogurt intake frequency and blood pressure. A cross-sectional study was designed using data from the National Health and Nutrition Examination Survey from 2003 to 2004 and 2005 to 2006. We included 3, 068 adults with blood pressure data and yogurt intake data. Multivariate regression analyses revealed significant inverse associations between yogurt and systolic blood pressure (P<0.05), diastolic blood pressure (P<0.05), and mean arterial pressure (P<0.05) in nonhypertensive participants (n = 1 822) but not in hypertensive participants (n = 1 246). Furthermore, a high frequency of yogurt intake prevented hypertension; however, no additional antihypertensive effects were observed in patients already diagnosed with hypertension.
Performance of the silica adsorbent from snake fruit peel for removing heavy metals of Ag, Cu, Mn, and Cr in SCW
Authors: Salamah Siti , Satar Ibdal
Published: May 2024

Silver crafts wastewater (SCW) typically contains environmentally harmful heavy metals, including Ag, Cu, Mn, and Cr, necessitating treatment before disposal. This study explores a promising solution using silica (SiO2) adsorbents derived from snake fruit peel through acidic activation with HCl concentrations of 2, 4, and 6 M. Qualitative analysis of the adsorbent involved Fourier-transform infrared spectrometer (FTIR) and x-ray fluorescence (XRF) techniques. XRF analysis revealed major compositions of Si (26%) and Cl (71.46%), with minor elements such as Ca (0.91%), P (0.42%), K (0.37%), Fe (0.12%), and others. FTIR analysis indicated the presence of siloxane (Si-O-Si) and silanol (Si-OH) on the adsorbent. The SiO2 adsorbent demonstrated effectiveness in removing heavy metals (Ag, Cu, Mn, and Cr) from SCW, achieving removal percentages of approximately 16.96%, 24.38%, 19.34%, and 9.82%, respectively. This research contributes to the development of an environmentally friendly approach for SCW treatment using silica adsorbents derived from agricultural waste.

Cavaleiros do Zodíaco: um mangá teopoético
Authors: Prilla João Paulo Vicente
Published: May 2024

It is an excerpt from a doctoral research that focuses on the manga Knights of the Zodiac (1985-1990), created by Masami Kurumada. Originally titled Saint Seiya, this Japanese comic book integrates Greek mythology as a structuring element of its narrative. The Greek mythology within the work is intersected by the combination of other themes - religion, astronomy, and astrology. Based on this amalgamation, Kurumada formulated a fundamental concept for the story: the cosmos, also known as the seventh sense. This is a complex and original idea that imparts a mystical and spiritual atmosphere to the manga. With that in mind, the objective of this article is to briefly explore the nature of the cosmos, conducting a theopoetic analysis of the work based on this concept. Therefore, the theoretical framework that underpins the study is primarily grounded in theopoetics (Kuschel, 1999; Ferraz, 2011; Bingemer; Villas Boas, 2020), which proposes comparative studies, initially between religion and literature, soon incorporating other artistic expressions - including comic books - into its research interests.

Published: May 2024

As histórias em quadrinhos não se limitam à sua própria linguagem de narrar histórias imagético-textuais, mas podem flertar com artes poéticas, visuais e além. Em diversos momentos, principalmente a partir da década de 1970, vimos experiências ricas na exploração livre da estrutura das histórias em quadrinhos. São exemplos a editora Le Terrain Vague, principalmente na publicação Saga de Xam, assim como Metal Hurlant e todo o quadrinho autoral que se estabelece a partir do período citado. No Brasil, essas investidas se mostram relevantes nos quadrinhos poético-filosóficos, mas também têm tido sua presença em produções que exploram a abstração nessa linguagem. O presente artigo procura localizar a antologia Autofagia, publicada pelo Selo Risco Impresso, dentro desse território da experimentação e autoralidade e como suas páginas abordam a vanguarda das histórias em quadrinhos e seu flerte com as artes, a poesia visual e o poema/processo.

El polimorfismo del espacio puede ser un factor importante para el desarrollo regional y el atractivo del territorio favorece la determinación de rutas para la expansión del ecoturismo. Este artículo se propone analizar el perfil de las Áreas Naturales Protegidas incluidas en el Programa de Concesión de Parques Estaduales de Minas Gerais, contribuyendo para avances en la gestión y monitoreo. Para ello, con base en la metodología del Índice de Atractivo Turístico, se establecieron los atributos biofísicos, sociales y de gestión de las 20 AP para fines de clasificación y posterior comparación respecto a la visitación promedio entre 2015 y 2019. Los resultados muestran que las áreas incluidas en el Programa se concentran en la Mata Atlántica (50%) o en su transición al Cerrado, están ubicados en regiones más desarrolladas y pobladas del estado. Además, son del tipo extensivo (65%), presentando, sin embargo, una gran diversidad en sus ambientes internos y externos. Con base en tal heterogeneidad, concluimos que es necesario impulsar nuevas alianzas público-privadas y la implementación de una administración basada en singularidades, en una antítesis de la masificación normativa actual, permitiendo así la ampliación de la mirada, para que todos los biomas puedan ser preservados, junto con el máximo de sus habilidades, único para cada área.
Nudges Podem Influenciar a Procura por Interpretação Ambiental em Áreas Protegidas? Estudo no Parque Estadual da Cantareira-SP
Authors: Martellotta Andre , Lobo Heros Augusto Santos
Published: May 2024

Environmental interpretation (IA) is an important component of ecotourism and public use in protected natural areas, as it provides information about biodiversity, ecosystems and environmental issues related to these places. However, understanding the factors that influence visitors to be interested in interpretive content is limited. In this context, research was conducted with the objective of identifying a behavioral direction in the search for interpretative content stimulated by nudges, with the help of mobile technology. The application of nudges, which are small interventions that seek to influence people's behavior in a subtle and non-coercive way, has proven increasingly relevant in several areas, including nature tourism. This is because these interventions can be applied in a non-intrusive way and can contribute to improving the visitor experience. The assumption was that, by reading the QR code installed at the entrance to a trail, visitors would be more interested in learning more about AI. Furthermore, it was tested whether social norm nudges would be more effective than direct questions in stimulating visitors' interest. The survey results showed that nudges were effective in sparking visitors' interest in AI. Furthermore, social norm nudges were more effective than direct questions. These results indicate that the use of nudges and gamification can be promising ways to increase visitors' interest in environmental themes in nature tourism itineraries.

Published: May 2024

Este estudo tem como objetivo compreender como mulheres empreendedoras do turismo fazem e desfazem gênero no seu empreender, buscando verificar ainda como elas desafiam a heteronormatividade binária de gênero existente no discurso do empreendedorismo. Foram realizadas entrevistas semiestruturadas com empreendedoras brasileiras do turismo, sendo os dados analisados por meio da técnica análise de conteúdo. A partir de uma ótica pós-estruturalista, pôde-se observar que as entrevistadas vivenciam no dia a dia expectativas de gênero que as pressiona a seguir certos padrões performáticos. Elas ora performam o feminino, ao lidar com o trabalho e o lar, desempenhando verdadeiros malabarismos como “mulheres polvo”; ora o masculino promulgando práticas ressignificativas no trabalho de maneira a atuar a partir de uma tendência estereotipadamente masculina. É possível perceber, a partir das análises realizadas, que a performance de gênero não é algo binário, sendo o masculino pertencente ao homem e o feminino a mulher, uma vez que indivíduos performam de diversas formas para sua sobrevivência social. As falas analisadas indicam que, o gênero varia de acordo com os espaços, corroborando com a problemática de performance de gênero desenvolvida Judith Butler. Este artigo evidencia as estratégias de enfrentamento utilizadas pelas empreendedoras frente aos desafios vividos, como assédio e machismo, resultando em performances que as levam a fazer e desfazer gênero nos diversos espaços sociais.

Módulos Experienciais, Memória e Intenções Comportamentais: a perspectiva dos turistasno Algarve, Portugal
Authors: Bender Ana , Lança Milene , Guerreiro Manuela , Pinto Patrícia
Published: May 2024

Para los destinos turísticos, el desarrollo de estrategias que utilicen la perspectiva del marketing de experiencias es vital para la competitividad, así como comprender cómo las experiencias que ofrecen determinan las decisiones de los turistas. A partir de lagunas en la literatura, se pretende contribuir a la comprensión de las relaciones entre los cinco módulos estratégicos de la experiencia de Schmitt (1999) - acción, sentimiento, sensación, pensamiento e identificación -, la memoria y las intenciones comportamentales de los turistas. Aunque la memoria y las intenciones de comportamiento se discuten ampliamente en la literatura, en el ámbito del marketing turístico, la influencia de cada dimensión experiencial, de forma aislada, aún requiere más investigación. A partir de una investigación empírica en el Algarve (sur de Portugal), se pretende comprender cómo los turistas experimentan el destino, así como analizar sus memorias y futuras intenciones de comportamiento. Entre los principales resultados, se destaca que, aunque de forma holística, la experiencia de consumo desempeña un papel categórico en la construcción de las intenciones de comportamiento de los turistas, cuando se tratan de forma aislada, los módulos experienciales presentan diferentes influencias en los turistas. Este fenómeno se produce, no sólo en sus intenciones de comportamiento, sino también en la construcción de sus memorias. Los resultados también señalan que, para reforzar la competitividad ante destinos similares, evitar la estacionalidad y revitalizarse como destino turístico, es fundamental que el Algarve se dedique a una planificación estratégica a largo plazo, centrada en el conocimiento de los diferentes segmentos turísticos.

Authors: Santos Glauber Eduardo de Oliveira
Published: May 2024

Este trabajo buscó preparar estimaciones de las dimensiones económicas del turismo en Brasil. La principal fuente de datos fue la Encuesta de Presupuestos Familiares 2017-2018 del IBGE. Este conjunto de datos ofreció una oportunidad sin precedentes para estimar la demanda turística de los hogares brasileños. Además, el presente trabajo adopta una estrategia de estimación innovadora basada en el cálculo de Cocientes de Participación del Turismo (QPT). Los QPT corresponden a la participación de los gastos relacionados con viajes turísticos en el total de gastos de los hogares con cada categoría de producto. Estos cocientes se aplicaron a datos del Sistema de Cuentas Nacionales, asegurando la compatibilidad de las estimaciones con la contabilidad nacional oficial. Los resultados se presentaron en el formato de Tablas de Origen y Destino. El PIB directo del turismo en 2018 se estimó en R$ 70 mil millones, lo que corresponde al 1% del PIB brasileño. Las actividades turísticas que más aportan al PIB son la hotelería y similares, los servicios de alimentación y el transporte aéreo. La investigación también destacó las principales deficiencias de datos para la elaboración de estimaciones más completas y consistentes, con énfasis en la falta de información sobre exportaciones turísticas, consumo turístico intermedio y gastos con vehículos, equipos y propiedades turísticas.

Educational Performance over Time: Changes in Mathematical Attainment between 1976 and 2009 in England
Authors: Hodgen Jeremy , Coe Robert , Brown Margaret , Küchemann Dietmar
Published: May 2024

Over the past fifty years, there have been substantial attempts to improve students’ mathematical performance around the world. Many commentators have criticised the efficacy of these initiatives, arguing that performance in western developed countries has either stagnated or fallen. Yet, there is limited robust comparative evidence available. This paper reports a replication of a study of student performance from the 1970s. In 2008 and 2009, in England, Grades 6–8 students (N ≈ 7000), in a nationally representative sample based on a stratified random sample of schools, were tested on their understandings of algebra, decimals, ratio and fractions. The survey used tests administered in 1976 and 1977 to an equivalent nationally representative sample of students. The findings indicate that, at Grade 8, overall understandings have generally fallen, although there are different patterns of change across the topics. The challenges of replicating studies where the full statistical findings are not available are considered.

Published: May 2024

Background:

The transition from primary to secondary school is a pivotal period in young people’s lives and can significantly impact their mental health. However, the experiences of young people from ethnically diverse groups during this crucial period of physical, social and emotional development are under-researched, limiting the evidence base for meaningful support.

Objectives:

This study explored the experiences of young people from ethnically diverse groups during primary-secondary school transition and co-designed ideas for culturally sensitive support. It explicitly focused on the intersection between ethnic and cultural identity, primary-secondary transition and mental health.

Methods:

The study employed participatory design to collaborate with seven young people from ethnically diverse groups and a peer researcher. Four online workshops mapped participant experiences and ideas concerning the primary-secondary transition, identity and mental health. These were developed into implications for practice, policy and research.

Results:

Participants highlighted feeling unprepared for the transition, with some experiencing poor mental health and difficulty navigating their ethnic and cultural identity during this time. Participants’ ideas for future transition experiences included: supporting a longer transition period, schools promoting diversity among students and staff, enabling education on ethnicity and culture, breaking stereotypes, enabling mutual learning among staff and students and enabling an open and caring environment to support mental health.

Conclusions:

The study provides an in-depth understanding of experiences of young people from ethnically diverse groups during primary-secondary transition and suggests ways of supporting multi-faceted transitions and mental health, with a key focus on ethnic and cultural identity formation.

Much has been made of Wagner Private Military Company’s (PMC) activities in Africa, and many have warned of Russia’s growing influence on the continent and the implications that this has for the West. But little work has been done to examine how African publics have reacted to these activities, even though one of the purposes of Wagner’s activities in Africa is to influence African public opinion. Have Wagner’s activities in Africa led to winning the battle for the “hearts and minds” of African publics on the continent, which appears to be, at least in part, the goal of such activities? Have they affected how Africans view Russia? Using data from a new report documenting Wagner political, military, and economic activities, coupled with recent Afrobarometer data from Wave 8 (2019–2021), I examine whether Wagner activities correlate with views on Russia. I find that rather than increasing positive evaluations of Russia, the presence of Wagner military activities is associated with a significant decrease in evaluations of Russia in the countries where Wagner is deployed. This suggests that Wagner activities may not be helping to improve Russia’s appeal in Africa.
Experimental investigation on the effects of stainless-steel mesh reinforcing layers on low-velocity impact response of hybrid thermoplastic glass fiber composites

Published: May 2024

This study aims to assess the hybridization effect on the perforation threshold of Low-Velocity Impact (LVI) in thermoplastic glass composite laminates, incorporating layers of resin-impregnated stainless-steel mesh. Reinforcing methodologies such as hybridization are recently being adopted as a practical approach to increasing the energy-absorbing capacity of polymer composites. In the current paper, a multi-step hot press lamination method has been employed to fabricate the hybrid composite laminates strengthened with stainless-steel mesh layers. Several stacking sequences, metal mesh wire sizes, orientation and position relative to the impactor have been examined under various LVI energies. It was revealed that the LVI penetration energy was increased for the thermoplastic-based composite laminates reinforced with stainless-steel mesh layers. Furthermore, the LVI penetration energy threshold was significantly influenced by the metal mesh wire size, orientation and stacking sequence. Finally, the backlight method capability was assessed to detect the after-impact interlaminar damages.
Some Reflections On The History And Current Status of Education in the Field of Death, Dying, and Bereavement at the College and University Level In North America

Published: May 2024

This article is a contribution to recording one dimension of the field of death, dying, and bereavement. It offers some personal reflections on the history and current status of formal education in this field at the college and university level in North America. The scope of this reflection looks back on the earliest known examples of formal education in this field that took place in the 1960s and 1970s, provides examples of some of the early pedagogical resources that were created to support and foster those initiatives, and sketches more recent developments as regards introductory or undergraduate survey courses in this field, other death-related courses, programs in thanatology, and efforts to offer certificates or certification for educators and other professionals in this field. The article concludes with some thoughts about what we have learned from and about education in the field of death, dying, and bereavement.
Megaprojects in austerity times: Populism, politicisation, and the breaking of the neoliberal consensus
Authors: Tarazona Vento Amparo
Published: May 2024

Drawing on the literature on neoliberalism and populism this paper examines the potential of contentious politics that target iconic megaprojects for promoting societal politicisation and effectively challenge the neoliberal consensus over the necessity of sustained growth and competitiveness, in a context of enduring austerity. Using the case of Valencia as an entry point, it looks at how, just as decision makers and global architects alike had mobilised iconic megaprojects and events to generate consent for the city’s neoliberal urban policy, opposition movements, with less economic resources but in innovative ways, provided an alternative narrative to interpret the urban policy and its social consequences. Empirically, this paper draws upon 35 semi-structured research interviews and a press coverage analysis of national and regional newspapers. Interviews were conducted with urban environment professionals, members of business associations, members of political parties, elected politicians, journalists, community representatives and members of the social movements involved. From both theoretical and empirical perspectives, the case of Valencia raises important questions regarding the potential of populist strategies to foster politicisation and challenge the neoliberal post-political consensus.

Introduction

The management of cardiopulmonary bypass (CPB) is still challenging in certain circumstances, especially for patients with anatomical variations. This challenge is even harder for reoperations, which are associated with increased morbidity and mortality risk.

Case report

We describe a minimally invasive, beating-heart redo tricuspid valve replacement in a 71-years old woman with persistent left superior vena cava.

Discussion

Preoperative planning via CT-scan, teamwork and custom-made management of CPB are crucial for reoperations with anatomical variations. The perfusionist has a pivotal role in constructing and managing the CPB.

Conclusion

We describe a strategy achieving the benefits of minimally invasive endoscopic and beating-heart surgery (avoidance of resternotomy risk and associated morbidity, right ventricular protection) in reoperative tricuspid surgery with persistent upper left vena cava.
The Social Contexts of Cultural Identity Among Adolescents of Immigrant Descent: Separate and Interacting Relations of Family and School Ethnic-Racial Socialization

Published: May 2024

This study explored the separate and interacting relations of family (cultural pluralism, promotion of mistrust) and school (equal treatment, intercultural learning) ethnic-racial socialization with cultural (heritage culture and German) identity among adolescents of immigrant descent. Analyses were based on survey data from 311 early to mid-adolescents in Germany ( M age = 13.85, SD = 1.82). Higher family cultural pluralism and intercultural learning at school were related to higher heritage culture identity, while higher equal treatment at school was related to lower heritage culture identity. Higher intercultural learning and equal treatment at school were related to higher German identity. Family promotion of mistrust had no direct relation to heritage culture or German identity. The interaction of family promotion of mistrust and equal treatment at school had relations to heritage culture but not to German identity. These findings expand our understanding of the complementary roles of family and school for supporting cultural identity development.
Danish Women Make Decisions about Participation in Breast Cancer Screening prior to Invitation Information: An Online Survey Using Experimental Methods

Published: May 2024

Introduction

At mammography screening invitation, the Danish Health Authority recommends women aged 50 to 69 y make an informed decision about whether to be screened. Previous studies have shown that women have very positive attitudes about screening participation. Therefore, we hypothesized that Danish women may already have decided to participate in breast cancer screening prior to receiving their screening invitation at age 50 y.

Methods

We invited a random sample of 2,952 Danish women aged 44 to 49 y (prescreening age) to complete an online questionnaire about barriers to informed screening decision making using the official digital mailbox system in Denmark. We asked participants about their screening intentions using 3 different questions to which women were randomized: screening presented 1) as an opportunity, 2) as a choice, and 3) as an opportunity plus a question about women’s stage of decision making. All women completed questions about background characteristics, intended participation in the screening program, use and impact of screening information, and preferences for the decision-making process. Data were linked to sociodemographic register data.

Results

A total of 790 (26.8%) women participated in the study. Herein, 97% (95% confidence interval: 96%–98%) reported that they wanted to participate in breast cancer screening when invited at age 50 y. When presented with the choice compared with the opportunity framing, more women rejected screening. When asked about their stage of decision making, most (87%) had already made a decision about screening participation and were unlikely to change their mind.

Conclusion

In our study, almost all women of prescreening age wanted to participate in breast cancer screening, suggesting that providing information at the time of screening invitation may be too late to support informed decision making.

Highlights

Almost all women of prescreening age (44–49 y) in our study wanted to participate in the Danish national mammography screening program starting at age 50 y. Early decision making represents a barrier for informed decision making as women in this study had intentions to participate in breast cancer screening prior to receiving an official screening invitation, and therefore, providing information at the time of screening invitation may be too late to support informed decision making. Very few women rejected screening participation; however, more women rejected screening when the information was framed as an active choice between having or declining breast cancer screening (continue with usual care) compared with presenting only the option of screening with no description of the alternative. Two-thirds of women reading the screening information in this study had unchanged attitudes toward screening after reading the presented information.
