Abstract
Background
Although there are various surgical causes of and therapeutic approaches to the chronically failing ileoanal pouch (PF), cases are often detailed without distinguishing the exact cause and corresponding treatment. The aim of our study was to classify causes of PF and corresponding surgical treatment options, and to establish efficacy of surgical approach per cause.

Methods
This retrospective study included all consecutive adult patients with chronic PF surgically treated at our tertiary hospital between July 2014 and March 2021. Patients were classified according to a proposed sub-classification for surgical related chronic PF. Results were reported accordingly.

Results
A total of 59 procedures were completed in 50 patients (64% male, median age 45 years [IQR 34.5–54.3]) for chronic PF. Most patients had refractory ulcerative colitis as indication for their restorative proctocolectomy (68%). All patients could be categorized according to the sub-classification. Reasons for chronic PF were septic complications (n = 25), pouch body complications (n = 12), outlet problems (n = 11), cuff problems (n = 8), retained rectum (n = 2), and inlet problems (n = 1). For these indications, 17 pouches were excised, 10 pouch reconstructions were performed, and 32 pouch revision procedures were performed. The various procedures had different complication rates. Technical success rates of redo surgery for the different causes varied from 0 to 100%, with a 75% success rate for septic causes.

Conclusions
Our sub-classification for chronic PF and corresponding treatments is suitable for all included patients. Outcomes varied between causes and subsequent management. Chronic PF was predominantly caused by septic complications with redo surgery achieving a 75% technical success rate.
Estimating surface optical properties and thermal thrust for Galileo satellite body and solar panels
Authors: Duan Bingbing , Hugentobler Urs 
Published: August 2022

AbstractPrecise orbit determination of GNSS (Global Navigation Satellite System) satellites requires accurate models of perturbing forces acting on the spacecraft, i.e., solar radiation pressure (SRP) and thermal radiation forces. With the officially published satellite metadata, the analytical box-wing model is usually used to describe most of the SRP accelerations and the rest is assumed to be compensated by estimating ECOM/ECOM2 (Empirical CODE Orbit Model) parameters. However, we find that the precision of Galileo satellite orbits shows notable degradation inside eclipse seasons for 3-day-arc solutions and 24-h predictions. For instance, the RMS (root-mean-square) of orbit misclosures increases by about a factor of two in the eclipse season when using the box-wing model as the a priori and the 5-parameter ECOM model on top. The reason is proven to be mostly due to ignoring imbalanced thermal radiation forces (i.e., radiator emission and thermal radiation of solar panels) as satellite thermal properties are unknown. These imbalanced thermal effects cannot be fully absorbed by the ECOM/ECOM2 parameters inside eclipse seasons because the earth’s shadowing of a satellite in orbit causes periodic changes of the thermal environment. To cope with this problem, we first estimate satellite optical and thermal parameters as part of orbit determination based on Galileo tracking data covering 1 year. Then, we add physical thermal radiation models for radiators and solar panels as part of the a priori model and evaluate the performance of different ECOM models in Galileo satellite orbit determination. As shown by orbit misclosures, 24-h orbit predictions and SLR (Satellite Laser Ranging) residuals, the 7-parameter ECOM2 model performs better than the 5-parameter ECOM and the 9-parameter ECOM2 model for Galileo satellites. When using the 7-parameter ECOM2 model on top, the impact of the radiator emission and the thermal radiation of solar panels on Galileo satellite orbits is about 1 and 2 cm, respectively, inside eclipse seasons for 3-day-arc solutions.
A comparison of regularization models for few-view CT image reconstruction
Authors: Loli Piccolomini Elena 
Published: August 2022

AbstractIn this paper I analyse some regularization models for the reconstruction of X-rays Computed Tomography images from few-view projections. It is well known that the widely used low-cost Filtered Back Projection method is not suitable in case of low-dose data, since it produces images with noise and artifacts. Iterative reconstruction methods based on the model discretization are preferred in this case. However, since the problem has infinite possible solutions and is ill-posed, regularization is necessary to obtain a good solution. Different iterative regularization methods have been proposed in literature, but an organized comparison among them is not available. We compare some regularization approaches in the case of few-view tomography by means of simulated projections from both a phantom and a real image.
On an Application of Jack’s Lemma, Starlikeness and k-Fold Symmetry in $${\mathbb {C}}^{n}$$
Authors: Długosz Renata , Liczberski Piotr 
Published: August 2022

AbstractIt is known that the starlikeness plays a central role in complex analysis, similarly as the convexity in functional analysis. However, if we consider the biholomorphisms between domains in$${\mathbb {C}}^{n},$$Cn,apart from starlikeness of domains, various symmetries are also important. This follows from the Poincaré theorem showing that the Euclidean unit ball is not biholomorphically equivalent to a polydisc in$${\mathbb {C}}^{n},n>1$$Cn,n>1. From this reason the second author in 2003 considered some families of locally biholomorphic mappings defined in the Euclidean open unit ball using starlikeness factorization and a notion ofk-fold symmetry. The 2017 paper of both authors contains some results on the absorption by a family$$S(k),k\ge 2,$$S(k),k≥2,of the above kind, the families of mappings biholomorphic starlike (convex) and vice versa. In the present paper there is given a new sufficient criterion for a locally biholomorphic mappingf, from the Euclidean ball$${\mathbb {B}}^{n}$$Bninto$${\mathbb {C}}^{n},$$Cn,to belong to the family$$S(k),k\ge 2.$$S(k),k≥2.The result is obtained using ann-dimensional version of Jack’s Lemma.
A Hippocratic Oath for Mathematicians? Mapping the Landscape of Ethics in Mathematics
Authors: Müller Dennis , Chiodo Maurice , Franklin James 
Published: August 2022

AbstractWhile the consequences of mathematically-based software, algorithms and strategies have become ever wider and better appreciated, ethical reflection on mathematics has remained primitive. We review the somewhat disconnected suggestions of commentators in recent decades with a view to piecing together a coherent approach to ethics in mathematics. Calls for a Hippocratic Oath for mathematicians are examined and it is concluded that while lessons can be learned from the medical profession, the relation of mathematicians to those affected by their work is significantly different. There is something to be learned also from the codes of conduct of cognate but professionalised quantitative disciplines such as engineering and accountancy, as well as from legal principles bearing on professional work. We conclude with recommendations that professional societies in mathematics should sponsor an (international) code of ethics, institutional mission statements for mathematicians and syllabuses of ethics courses for incorporation into mathematics degrees.
Towards a Design Toolkit of Informed Consent Models Across Fields: A Systematic Review
Authors: Loosman Iris , Nickel Philip J. 
Published: August 2022

AbstractIn the 60+ years that the modern concept of informed consent has been around, researchers in various fields of practice, especially medical ethics, have developed new models to overcome theoretical and practical problems. While (systematic) literature reviews of such models exist within given fields (e.g., genetic screening), this article breaks ground by analyzing academic literature on consent models across fields. Three electronic research databases (Scopus, Google Scholar, and Web of Science) were searched for publications mentioning informed consent models. The titles, abstracts, and if applicable, full publications were screened and coded. The resulting data on fields, models, and themes were then analyzed. We scanned 300 sources from three databases to find 207 uniquely named consent models, and created a network visualization displaying which models occur primarily in one field, and which models overlap between fields. This analysis identifies trends in the consent debate in different fields, as well as common goals of consent models. The most frequently occurring consent models are identified and defined. The analysis contributes toward a cross-disciplinary “consent design toolkit” and highlights that there are more interrelationships between models and fields than are acknowledged in the literature. Where some models are designed to solve distinctively field-specific issues and are specific to biomedical ethics, some may be adaptable and applicable for other fields including engineering and design.

AbstractAn increasing number of evidences have shown that the carcinogenic effect of DRAXIN plays an important role in the malignant process of tumors, but the mechanism of its involvement in glioma has not yet been revealed. The main aim of this study is to explore the relationship between DRAXIN and the prognosis and pathogenesis of glioma through a large quality of data analysis. Firstly, thousands of tissue samples with clinical information were collected based on various public databases. Then, a series of bioinformatics analyses were performed to mine data from information of glioma samples extracted from several reputable databases to reveal the key role of DRAXIN in glioma development and progression, with the confirmation of basic experiments. Our results showed that high expression of the oncogene DRAXIN in tumor tissue and cells could be used as an independent risk factor for poor prognosis in glioma patients and was strongly associated with clinical risk features. The reverse transcription-quantitative PCR technique was then utilized to validate the DRAXIN expression results we obtained. In addition, co-expression analysis identified, respectively, top 10 genes that were closely associated with DRAXIN positively or negatively. Finally, in vitro experiments demonstrated that knockdown of DRAXIN significantly inhibited proliferation and invasion of glioma cell. To sum up, this is the first report of DRAXIN being highly expressed in gliomas and leading to poor prognosis of glioma patients. DRAXIN may not only benefit to explore the pathogenesis of gliomas, but also serve as a novel biological target for the treatment of glioma.

AbstractThe use of photosynthetic biohybrids to drive redox reactions in vitro is a promising strategy due to the natural abundance and high quantum efficiency of the bio-components. Here, we present different tools for the fabrication of photosystem I-based biohybrid devices by using redox-active polymers, 3D-structured electrodes as well as additional light-harvesting antennae modules.
Towards a Comparative Study of Animal Consciousness
Authors: Veit Walter 
Published: August 2022

AbstractIn order to develop a true biological science of consciousness, we have to remove humans from the center of reference and develop a bottom-up comparative study of animal minds, as Donald Griffin intended with his call for a “cognitive ethology.” In this article, I make use of the pathological complexity thesis (Veit 2022a, b, c) to show that we can firmly ground a comparative study of animal consciousness by drawing on the resources of state-based behavioral life history theory. By comparing the different life histories of gastropods and arthropods, we will be able to make better sense of the possible origins of consciousness and its function for organisms in their natural environments.
Forms of Interreligious Encounter in Contemporary Nigerian Fiction
Authors: Suhr-Sytsma Nathan 
Published: August 2022

AbstractAfricanist scholars continue to debate how best to frame Christian-Muslim encounters. Examining literary fiction that portrays interreligious conflict and dialogue in northern Nigeria, Suhr-Sytsma opens up an exchange between social scientists and Nigerian writers including Chimamanda Ngozi Adichie, Uwem Akpan, Abubakar Adam Ibrahim, and E. E. Sule. Suhr-Sytsma argues that, as social thinkers, Nigerian writers explore interreligious solidarity through forms of doubling and critique forms of sacrifice that authorize scapegoating. Consequently, contemporary Nigerian fiction raises fundamental questions not only about the relation of text to reality but also about the making and crossing of boundaries identified as religious.

Published: August 2022

AbstractObjective:To describe healthcare provider, veteran, and organizational barriers to, challenges to, and facilitators of implementation of the oral care Hospital-Acquired Pneumonia Prevention by Engaging Nurses (HAPPEN) initiative to prevent non–ventilator-associated hospital-acquired pneumonia (NV-HAP).Design:Concurrent mixed methods. Qualitative interviews of staff and patients were conducted in addition to a larger survey of VA employees regarding implementation.Setting:Medical surgical or extended care units in 6 high-complexity (01a–c) VA hospitals.Participants:Between January 2020 and February 2021, we interviewed 7 staff and 7 veterans, and we received survey responses from 91 staff.Intervention:Provide education, support, and oral care supplies to prevent NV-HAP.Results:Barriers to HAPPEN implementation and tracking at the pilot sites included maintaining oral care supplies and completion of oral care documentation. Facilitators for HAPPEN implementation included development of supportive formal and informal nurse leaders, staff engagement, and shared beliefs in the importance of care quality and infection prevention. Nurses worked together as a team to provide consistent oral care. Oral care was viewed as an essential infection control practice (not just “a task”) and was considered part of the “culture” and “mission” in caring for veterans.Conclusions:Nurse leaders and direct-care staff were engaged throughout HAPPEN implementation, and most reported feeling supported and well prepared as they walked through the steps. Veterans reported positive experiences and increased knowledge about prevention of pneumonia. Lessons learned included building a community of practice and sharing expertise, which led to the successful replication of the HAPPEN initiative nationwide, improving patient safety and care quality and influencing health policy.
The lives and work of Bob Dylan
Authors: Frith Simon 
Published: August 2022

According to the website Come writers and critics, which keeps a running list of all ‘documents related to Bob Dylan printed on paper’, by the end of 2021 (Dylan's 80th year), there were 829 books about him in English and 723 in 36 other languages (from 175 in German to one each in Bulgarian and Vietnamese).1 The list is indiscriminate in terms of the various books’ quality, originality or readability, but looking at the bibliographies of the various works I'm reviewing here, it seems that there are at least 50 Dylan books that academic Dylanologists take seriously (and many more journal articles).2 From this perspective, my four titles provide a useful cross-section of the most common academic Dylan studies in disciplinary terms: biography, literary criticism, musicology and cultural studies. I should also note that in March 2016 the George Kaiser Family Foundation bought Bob Dylan's personal archive (for $22 million according to Heylin) and gave it a permanent home in Tulsa. This has opened up significant new research possibilities. In its own words:
The Bob Dylan Archive® highlights the unique artistry and worldwide cultural significance of Bob Dylan. Housed at the University of Tulsa's Helmerich Center for American Research at Gilcrease Museum, the archive includes decades of never-before-seen handwritten manuscripts, notebooks and correspondence; films, videos, photographs and artwork; memorabilia; personal documents; unrecorded song lyrics and chords.
Like the writer and composer archives to be found in many university libraries, the Bob Dylan collection is accessible onsite (and by appointment) to ‘individuals with qualified research projects’, and The World of Bob Dylan is, in effect, a celebration of a new era for Dylan scholarship. Its editor, Sean Latham, is the Director of the related Institute for Bob Dylan Studies.3 However, the first book to draw on the Bob Dylan Archive systematically is Clinton Heylin's The Double Life.
Long-term results of biventricular correction for patients with double outlet right ventricle
Authors: Wang Zhangwei , Li Zhiqiang 
Published: August 2022

AbstractObjectives:The purpose of this study was to report outcomes of double outlet right ventricle biventricular repair at a single institution in developing countries and to investigate post-operatively determined risk factors for mortality and late intervention.Methods:Patients with double outlet right ventricle who underwent biventricular repair in our centre from January 2009 to December 2021 were included.Results:A total of 96 patients (male/female = 61/35) with biventricular repair were included. According to its specific anatomical type, the appropriate individual surgical plan was selected. Multivariate analysis indicated that prolonged cardiopulmonary bypass time(OR = 1.044; p = 0.012) and pre-operative moderate or above pulmonary hypertension(OR = 24.558; p = 0.023) were independent risk factors for early mortality. Univariate analysis showed that different anatomical types and different surgical methods had similar late intervention and late mortality. Concomitant coarctation of the aorta(OR = 40; p = 0.020) and concomitant ventricular septal defect enlargement(OR = 26.667; p = 0.005) were independent risk factors for late intervention by multivariate analysis.Conclusion:Selection of appropriate surgical techniques based on different anatomical types often results in similar late outcomes. For patients with concomitant ventricular septal defect enlargement during the operation, it is necessary to fully expand and avoid damage to the conduction bundle. We should timely intervention in patients with coarctation of the aorta and pay attention to the occurrence of left ventricular outflow tract obstruction during follow-up.
Patent ductus arteriosus ligation under high-frequency oscillatory ventilation in two critically ill pre-mature newborns

Published: August 2022

AbstractInformation on the use of high-frequency oscillatory ventilation in neonatal surgeries is very rare. In this report, we discuss two pre-term infants who had to receive high-frequency oscillatory ventilation as a rescue treatment due to severe pre-maturity. These two cases underwent successful bedside patent ductus arteriosus ligation under high-frequency oscillatory ventilation, and this shows us that patent ductus arteriosus ligation can be performed successfully in neonates even under high-frequency oscillatory ventilation.
Erosion Behavior of Sand‐Silt Mixtures: Revisiting the Erosion Threshold
Authors: Yao Peng , Su Min , Wang Zhengbing , van Rijn Leo C. , Stive Marcel J. F. , Xu Chunyang , Chen Yongping 
Published: August 2022

AbstractThe erosion threshold, beyond which bed sediments start to move, is a key parameter describing sediment transport processes. For silt‐dominated mixtures, in which the grain size is between sand and clay, existing experimental studies exhibit contradictory observations. That is, the erosion was either sand‐like or clay‐like, suggesting transitional erosion behavior. To explore the underlying mechanism of the transitional erosion behavior of silt‐sized sediment, we revisited the topic of the erosion threshold of sand‐silt mixtures by carrying out a series of erosion experiments for different bed compositions. The results suggest that there exists a critical silt content of approximately 35%, separating two domains. Below this critical value, the critical bed shear stress follows the Shields criterion, whereas above this value, the erosion threshold of a mixed bed increases abruptly and remains relatively constant with a further increase in silt content. By combining with existing data, we found that the proposed critical silt content acts as a tipping point, beyond which the mixed bed shifts from a sand‐dominated to a silt‐dominated domain. For the silt‐dominated domain, a stable silt skeleton can be formed by attraction forces that resist erosion. However, the attraction forces are too weak to form a stable silt skeleton when the silt content is too small. Based on this finding, a modified critical bed shear stress formula is proposed for silt‐dominated mixtures, which results in a better agreement with experimental data (an averaged bias of 10%), performing better than existing formulas (larger than 30%).
Urban Soil Safety Policies: The Next Frontier for Mitigating Lead Exposures and Promoting Sustainable Food Production

Published: August 2022

AbstractUrban soils bear the persistent legacy of leaded gasoline and past industrial practices. Soil safety policies (SSPs) are an important public health tool with the potential to inform, identify, and mitigate potential health risks faced by urban growers, but little is known about how these policies may protect growers from exposures to lead and other soil contaminants. We reviewed and evaluated 43 urban agriculture (UA) policies in 40 US cities pertaining to soil safety. About half of these cities had a least one SSP that offered recommendations or provided services for soil testing. Eight cities had at least one SSP containing a requirement pertaining to any topic (e.g., soil testing, a specific best practice for growing). We found notable inconsistencies across SSPs for “acceptable” levels of lead in soils and the activities and behaviors recommended at each level. We specify research needed to inform revisions to US Environmental Protection Agency guidance for lead in soils specific to UA. We conclude with a series of recommendations to guide the development or revision of SSPs.
