AbstractIntroduction and ObjectivePerioperative antimicrobial prophylaxis is crucial for prevention of prosthesis and patient morbidity after artificial urinary sphincter (AUS) placement. While antibiotic guidelines exist for many urologic procedures, adoption patterns for AUS surgery are unclear. We aimed to assess trends in antibiotic prophylaxis for AUS and outcomes relative to American Urological Association (AUA) Best Practice guidelines.MethodsThe Premier Healthcare Database was queried from 2000 to 2020. Encounters involving AUS insertion, revision/removal, and associated complications were identified via ICD and CPT codes. Premier charge codes were used to identify antibiotics used during the insertion encounter. AUS‐related complication events were found using patient hospital identifiers. Univariable analysis between hospital/patient characteristics and use of guideline‐adherent antibiotics was done via chi‐squared and Kruskal–Wallis tests. A multivariable logistic mixed effects model was used to assess factors related to the odds of complication, specifically the use of guideline‐adherent versus nonadherent regimens.ResultsOf 9775 patients with primary AUS surgery, 4310 (44.1%) received guideline‐adherent antibiotics. The odds of guideline‐adherent regimen use increased 7.7% per year with 53.0% (830/1565) receiving guideline‐adherent antibiotics by the end of the study period. Patients with guideline‐adherent regimens had a decreased risk of any complication (odds ratio [OR]: 0.83, 95% confidence interval [CI]: 0.74–0.93) and surgical revision (OR: 0.85, 95% CI: 0.74–0.96) within 3 months; however, no significant difference in infection within was noted (OR: 0.89, 95% CI: 0.68–1.17) within 3 months.ConclusionsAdherence to AUA antimicrobial guidelines for AUS surgery appears to have increased over the last two decades. While guideline‐adherent regimens were associated with decreased risk of any complication and surgical intervention, no significant association was found with risk of infection. Surgeons appear to be increasingly following AUA recommendations for antimicrobial prophylaxis for AUS surgery, however, further level 1 evidence should be obtained to demonstrate conclusive benefit of these regimens.

Published: May 2023

AbstractMobile edge computing (MEC) integrates mobile and edge computing technologies to provide efficient computing services with low latency. It includes several Internet of Things (IoT) and edge devices that process the user data at the network's edge. The architectural characteristic of MEC supports many internet‐based services, which attract more number of users, including attackers. The safety and privacy of the MEC environment, especially user information is a significant concern. A lightweight accessing and sharing protocol is required because edge devices are resource constraints. This paper addresses this issue by proposing a blockchain‐enabled security management framework for MEC environments. This approach provides another level of security and includes blockchain security features like temper resistance, immutable, transparent, traceable, and distributed ledger in the MEC environment. The framework guarantees secure data storage in the MEC environment. The contributions of this paper are twofold: (1) We propose a blockchain‐enabled security management framework for MEC environments that address the security and privacy concerns, and (2) we demonstrate through simulations that the framework has high performance and is suitable for resource‐constrained MEC devices. In addition, a smart contract‐based access and sharing mechanism is proposed. Our research uses a combination of theoretical analysis and simulation experiments to demonstrate that the proposed framework offers high security, low latency, legitimate access, high throughput, and low operations cost.
Considerations on the identifiability of fracture and bond properties of reinforced concrete
Authors: Dobrilla Simona , Matthies Hermann G. , Ibrahimbegovic Adnan 
Published: May 2023

AbstractThis work tackles the issue of identifiability of fracture and bond properties in reinforced concrete. The basis for modeling of fracture is a computational model capable of describing damage and failure mechanisms in concrete, as well as bond‐slip which is a result of degradation of the concrete‐steel interface. The discrete approximation combines ED‐FEM for concrete crack representation in each element and X‐FEM representation of bond‐slip along a particular reinforcement bar. The uncertain model parameters are modeled as random variables and identified via Bayesian inference with the help of observations from tensile tests on concrete tie beams with a single embedded reinforcement bar. We discuss how the choice of observation type affects the parameter identifiability and propose combinations which improve the estimation capabilities and reduce the discrepancy between the computed and observed quantities of interest.
A comparative analysis of resource networks of intermediary support organizations for nonprofit development: Evidence from incubators for nonprofit organizations
Authors: Liu Zejin , Van de Walle Steven 
Published: May 2023

AbstractIncubators for nonprofit organizations (NPOs) are agencies that provide diverse services to support the creation, survival, and early stage growth of NPOs. A primary task of such agencies is to provide NPO clients access to resources through networking. Drawing on the literature on intermediary support organizations (ISOs) and tie formation and a comparative case study of three incubators for NPOs in China, this study examines differences in their resource networks for supporting NPOs and the various factors associated with those different network characteristics. The analysis shows that the types of organizations that play a pivotal role in each case's resource network—business organizations, governmental organizations, and NPOs—are different. Each of these distinctive network characteristics is individually associated with organizational influence, resource dependence, and institutional design. These differences in resource networks and the mechanisms underlying network formation contribute to the literature on ISOs.

AbstractAimThe aim of the study was to find differences in perceived reasons for implicit rationing of nursing care across hospital types and units.DesignA descriptive multicentre study.MethodsThe study in 14 Czech acute care hospitals was conducted from September 2019 to October 2020. The sample consisted of 8316 nurses working in medical and surgical units. Items for rating the reasons for implicit rationing of nursing care were selected from the MISSCARE Survey. Nurses were asked to rate each item on a scale from 0 (a not significant reason) to 10 (the most significant reason).ResultsThe most significant reasons for implicit rationing of nursing care were ‘Inadequate number of staff’, ‘Inadequate number of assistive personnel’ and ‘Unexpected patient admission and discharge’. Most reasons were rated as more significant by nurses from non‐university hospitals. Nurses from medical units perceived all reasons for implicit rationing of nursing care as more significant.

AbstractAimTo determine the associated factors of professional identity among intensive care unit (ICU) nurses during the COVID‐19 pandemic in China.DesignMulticentre cross‐sectional study.MethodsThis study invited 348 ICU nurses in five hospitals in China from May to July 2020. Online self‐report questionnaires were adopted to collect their demographic and occupational characteristics, perceived professional benefits and professional identity. Based on univariate and multiple linear regression analysis, a path analysis was performed to determine the associated factors' effects on professional identity.ResultsThe mean score of professional identity was 102.38 ± 16.46. Perceived professional benefits, doctor recognition level and family support level were associated with ICU nurses' professional identity. The path analysis revealed that perceived professional benefits and doctor recognition level had direct effects on professional identity. In addition, doctor recognition level and family support level had indirect effects on professional identity through the mediation of perceived professional benefits.

AbstractAimThis study was to investigate the association between character strengths and job crafting among nurses in tertiary hospitals in China.DesignA cross‐sectional survey was conducted.MethodsFrom February 2021 to April 2021, 1006 nurses from four tertiary hospitals in China were recruited to complete a series of online questionnaires assessing their job crafting and character strengths. The analysis was conducted using structural equation modelling (SEM).ResultsThe mean scores for task crafting, cognitive crafting and relationship crafting were 3.19 ± 0.58, 3.50 ± 0.55 and 3.58 ± 0.51. There is a moderate level of job crafting and character strengths among Chinese nurses working at tertiary hospitals. Additionally, it was revealed by the SEM that character strengths contributed to 81% of the variance of job crafting and job crafting was positively correlated with nurses' character strengths. The study shows the need to develop nurses' character strengths to enhance job crafting behaviours.

AbstractAimTo describe the impact on nursing practice of using continuous pulse oximetry monitoring to monitor patients at high risk for respiratory depression after surgery.DesignA convergent mixed method design.MethodsThirty (30) hours of non‐participant structured observation and explanatory interviews were conducted with 10 nurses from the surgery care unit and intensive care unit.ResultsWe found that nursing practice to evaluate and monitor at‐risk patients through continuous pulse oximetry monitoring is mainly linked to technical care. Nurses generally meet the frequency of bedside monitoring required by established protocols. During the structured non‐participant observation periods, it was observed that 90% of the alarms were false (unsustained desaturations). This was confirmed by the nurses during the explanatory interviews. Noisy environments, high number of false alarms, poor communication between nurses and various operational failures might have a negative impact on nursing practice.ConclusionSeveral challenges must be overcome for this technology to achieve the desired outcomes of continuous surveillance and rapid detection of respiratory depression episodes for post‐surgical patients.No Patient or Public Contribution.

Authors: Manakhov Pavel D. , Evteev Andrej A. 
Published: May 2023

AbstractThe ecogeographic trends in the shape of the internal nasal cavity and external facial skeleton were explored in a sample of Mesolithic, Neolithic, and Bronze Age skulls from Northeastern Europe and the Caucasus and tested against a background of the variation in recent populations from the same area. The volume, surface area, and several linear dimensions of the internal nasal cavity as well as a set of 3D landmarks of the external mid‐face were collected in a sample of computed tomography (CT) scans of 121 adult male skulls from six modern human populations of Eastern Europe, Anatolia, and Caucasus (74 individuals) and seven ancient burial sites (47 individuals). Various measures of the association between nasal cavity morphology and climate revealed moderate to high levels of correlation. The modern populations from colder climates and all but one ancient group display a substantial decrease in the nasal cavity heights and widths, volume and nasal protrusion, a relative narrowing of the nasal cavity, and a substantial increment in length of the maxillary part of the cavity. These groups also exhibit a less protruding external nose, smaller orbits, and a vertically taller zygomatic region. Our results show that the suite of morphological features associated with living in a cold climate is more strongly pronounced in ancient Europeans compared with the Medieval or modern groups of the same continent.
Size effect and scaling in quasi‐static and fatigue fracture of graphene polymer nanocomposites
Authors: Qiao Yao , Guo Kaiwen , Salviato Marco 
Published: May 2023

AbstractThis work investigated how the structure size affects the quasi‐static and fatigue behaviors of graphene polymer nanocomposites, a topic that has been often overlooked. The results showed that both quasi‐static and fatigue failure of these materials scale nonlinearly with the structure size due to the presence of a significant fracture process zone (FPZ) ahead of the crack tip induced by graphene nanomodification. Such a complicated size effect and scaling in either quasi‐static or fatigue scenario cannot be described by the linear elastic fracture mechanics, but can be well captured by the size effect law (SEL) which considers the FPZ. Thanks to the SEL, the enhanced quasi‐static and fatigue fracture properties were properly characterized and shown to be independent of the structure size. In addition, the differences on the morphological and mechanical behaviors between quasi‐static fracture and fatigue fracture were also identified and clarified in this work. The experimental data and analytical analyses reported in this article are important to deeply understand the mechanics of polymer‐based nanocomposites and even other quasi‐brittle materials (e.g., fiber‐reinforced polymers or their hybrid with nanoparticles, and so forth), and further advance the development of computational models capable of capturing size‐dependent fracture of materials under various loads.
