Published: May 2024

AbstractBackgroundThis systematic review aggregates the data of studies that include site‐specific analyses of patients undergoing salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma.MethodsThe primary outcomes are disease‐free, disease‐specific, and overall survival (DFS, DSS, and OS, respectively). Secondary outcomes include complications and postoperative feeding requirements.ResultsFifteen studies met the inclusion criteria with a total of 442 patients. Two‐year DFS is reported from 30.0 to 50.0% and 5‐year DFS ranges from 15.0 to 57.1%. Five‐year DSS ranges from 28.0 to 57.1%. Two‐year OS ranges from 38.8 to 52.0% and 5‐year OS ranges from 15.5 to 57.1%. Complications include pharyngocutaneous fistula (0.0–71.4%), carotid artery rupture (2.9–13.3%), and stomal stenosis (4.2–20.0%). Complete oral feeding achieved following surgery ranges from 61.9 to 100.0%, while complete gastrostomy tube dependence ranges from 0.0 to 28.6%.ConclusionsSalvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma has a relatively high complication rate and should be offered to patients with the understanding of a guarded prognosis.

Authors: Jones Katheryn , Crawford Gemma , Mahboub Lyn , Jancey Jonine 
Published: May 2024

AbstractBackgroundRecovery Colleges (RCs) represent an approach to enhancing mental wellbeing through education, lived experience and co‐production. Despite their increasing presence, scant literature explores the operationalisation of RCs and their embodiment of co‐production principles. The aim of this scoping review was to investigate the operationalisation of RCs and their application of co‐production in RCs located in high‐income countries over the past decade.MethodsEmploying an established scoping review methodology, searches were conducted across seven academic databases. Ten primary studies met the inclusion criteria. In addition, stakeholders were consulted to validate themes and uncover knowledge gaps.ResultsFindings suggest that RCs are inherently idiosyncratic, adapted to suit local contexts. Discussions persist regarding their optimal institutional contexts and positioning and the interpretation of key terms such as ‘recovery’ and ‘co‐production’, influencing daily operations and stakeholder involvement. Challenges surrounding measuring success against fidelity criteria underscore the need for a broader understanding of RC value and sustainability.ConclusionThis review offers a synopsis of the existing literature offering insights concerning the operationalisation of RCs. Through a synthesis of diverse primary studies, it systematically identifies and describes the operational nuances within the RC landscape and the fundamental elements underpinning RC operations, while shedding light on critical knowledge gaps in both research and practice.So What?This review underscores the importance of a broader understanding of RC value and sustainability, offering insights for both research and practice in the field of mental health and wellbeing. This review highlights the significance of further exploration and refinement of RC operationalisation to enhance their effectiveness and impact in supporting mental wellbeing.
Bilateral investment treaties and sovereign default risk: Evidence for emerging markets
Authors: Eichler Stefan , Nauerth Jannik André 
Published: May 2024

AbstractThis paper analyses the impact of bilateral investment treaties (BITs) on sovereign default risk using monthly data for 29 emerging markets from 1996 to 2016. Under a BIT, foreign investors can use an international arbitration scheme to enforce compensation claims against the host country's government. We focus on the so far unexplored legal risk associated with BITs since a higher likelihood of government expropriations implicitly increases public debt. We do not find a significant unconditional effect of BITs on sovereign default risk (measured by the month‐over‐month percentage change in a country's Emerging Market Bond Index). Considering the heterogeneity of BITs and political risk, we find robust and strong negative effects of BITs on sovereign bond returns. In countries with high political risk of expropriation (measured by low executive constraints), we find that the implementation of BITs with strong investor protection is associated with a significantly negative impact on sovereign bond returns (−0.45 percentage points), which compares to roughly 11.7% of bond returns' monthly standard deviation.

AbstractObjectivesThere remains an unmet need for a laser‐enabled tissue coring device that can effectively improve face and neck skin laxity and rhytides. We investigate a novel 2910 nm erbium‐doped fluoride glass fiber laser (2910 nm fiber laser) (UltraClear; Acclaro Medical) for laser‐coring of submental tissue.MethodsFive subjects, Glogau scale III−IV, were treated with a single pulse of the laser‐coring mode of the 2910 nm fiber laser in the submentum. A 4 mm punch biopsy was immediately performed. Biopsy specimens were sectioned and stained with hematoxylin and eosin and placed on glass slides. All sections were reviewed, and sections containing the center of the transected core were analyzed for depth and diameter of the ablative microchannel and width of the surrounding zone of coagulation.ResultsA total of 15 intact micro‐cores were analyzed. Histological analysis revealed an average ± standard deviation microchannel diameter of 242.5 ± 65.2 µm, an average ablative depth of 980 ± 318.8 µm, and an average zone of coagulation of 104 ± 32 µm.ConclusionsLaser‐enabled tissue coring with a novel 2910 nm fiber laser can safely achieve a wider microchannel diameter with ablative depth extending to the mid and deep dermis, which has the potential for collagen contraction and tissue tightening. Laser‐coring to this ablation diameter and depth and with the surrounding zone of coagulation was found to be safe without adverse effects of post‐inflammatory erythema or scarring in our study.
Self‐gifting and temporal selves: Insights from first‐time older motherhood
Authors: Liu Chihling , Karanika Katerina , Hogg Margaret K. 
Published: May 2024

AbstractPrior literature has long established self‐gifts as a form of symbolic self‐communication that can be particularly meaningful and impactful for individuals to enhance self‐concept clarity and self‐definition during life transitions. However, little is known about how life transitions may bring about changes in the practices and meanings of self‐gifting. Drawing on individual interviews with 22 first‐time older mothers, this research uses temporal self‐appraisal theory as the theoretical lens and temporal landmarks as a sensitizing framework to explore how people's past, present, and future selves may unfold and interact in influencing their self‐gifting practices and meanings. Our findings contribute to a fuller understanding of the temporal nature of self‐gifting by highlighting the varying self‐gifting orientations that emerge from the interaction, reflecting changes in temporal self‐appraisals and how they enable a sense of self‐(dis)continuity for psychological well‐being. The temporal perspective of self‐gifts offers a theoretical framework for understanding how self‐gifts, a form of symbolic self‐communication, express, manage, or facilitate perceived self‐changes and the need for self‐continuity. The marketing implications and applications of the theoretical framework are also discussed.

Published: May 2024

AbstractAll provinces of China respond to the central government, predict future carbon dioxide emissions, and formulate action plans detailing how the province intends to fulfill its target of carbon emission peaking before 2030. Based on the bottom‐up energy consumption prediction and top‐down goal verification, this paper constructs a set of regional carbon dioxide emission prediction methods. Compared to the traditional bottom‐up prediction method, this method could simplify the parameters while improving the prediction accuracy. This model is used to predict and analyze the process of carbon dioxide emission peaking in Zhejiang. The results show that the mean absolute percentage error of the retrospective prediction value is only 1.56%. Zhejiang will reach carbon dioxide emission peaking around 2029–2030, and the peak value will be 569.7 million tons. Different factors have different effects on the process of carbon dioxide emission peaking. There is a strong correlation between the peak time of carbon dioxide emission and the production time of major energy‐consuming projects in Zhejiang. Meanwhile, if the 16 nuclear reactors are not put into operation, Zhejiang will not be able to achieve the goal of carbon dioxide emission peaking. Besides, the basic data used in this model is mainly from the local statistical departments of the region. Thus, it can be applied to other provinces and regions conveniently.
Assessing the impact of bias correction approaches on climate extremes and the climate change signal

Published: May 2024

AbstractWe assess the impact of three bias correction approaches on present day means and extremes, and climate change signal, for six climate variables (precipitation, minimum and maximum temperature, radiation, vapour pressure and mean sea level pressure) from dynamically downscaled climate simulations over Queensland, Australia. Results show that all bias‐correction methods are effective at removing systematic model biases, however the results are variable and season‐dependent. Importantly, our results are based on fully independent cross‐validation, an advantage over similar studies. Linear scaling preserves the climate change signals for temperature, while quantile mapping and the distribution‐based transfer function modify the climate change signal and patterns of change. The Perkins score for all the values above the 95th percentile and below the 5th percentile was used to evaluate how well the climate model matches the observational data. Bias correction improved Perkins score for extremes for some variables and seasons. We rank the bias‐correction methods based on the Kling–Gupta efficiency (KGE) score calculated during the validation period. We find that linear scaling and empirical quantile mapping are the best approaches for Queensland for mean climatology. On average, bias correction led to an improvement in the KGE score of 23% annually. However, in terms of extreme values, quantile mapping and statistical distribution‐based transfer function approaches perform best, and linear scaling tends to perform worst. Our results show that, except linear scaling, all approaches impact the climate change signal.

Published: May 2024

AbstractThe primary aim of this work is to investigate the use iron di‐silicide (FeSi2) as a photoactive layer in order to achieve superior performance in the solar cell architecture—ITO/TiO2/FeSi2/CuSCN/Ni. The optimum thickness of the absorber layer was found to be 1000 nm, which gave optimal properties of the proposed cell—a short‐circuit current density (Jsc) of 51.41 mAm−2, an open‐circuit voltage (Voc) of 0.93 V, a fill factor (FF) of 77.99%, and power conversion efficiency (PCE) of 37.17%. The introduction of an ultrathin interfacial layer between the electron transport layer (ETL), the perovskite interface, and the hole transport layer (HTL) enhanced the electrical output of the proposed solar cell. The Jsc increased to 51.86 mAcm−2, Voc rose to 0.97 V, while FF and PCE increased to 82.86% and 41.84%, respectively. Accordingly, the proposed cell architecture is promising and can be introduced into the manufacturing workflow for commercial applications. Moreover, because of its exceptional photon absorption capabilities, FeSi2 is a potentially excellent photoactive material for solar cell fabrication. The detailed findings of this study have therefore indicated that high‐performance FeSi2‐based solar can be achieved in future.
Diffusion magnetic resonance imaging of cerebrospinal fluid dynamics: Current techniques and future advancements
Authors: Wright Adam M. , Wu Yu‐Chien , Feng Li , Wen Qiuting 
Published: May 2024

AbstractCerebrospinal fluid (CSF) plays a critical role in metabolic waste clearance from the brain, requiring its circulation throughout various brain pathways, including the ventricular system, subarachnoid spaces, para‐arterial spaces, interstitial spaces, and para‐venous spaces. The complexity of CSF circulation has posed a challenge in obtaining noninvasive measurements of CSF dynamics. The assessment of CSF dynamics throughout its various circulatory pathways is possible using diffusion magnetic resonance imaging (MRI) with optimized sensitivity to incoherent water movement across the brain. This review presents an overview of both established and emerging diffusion MRI techniques designed to measure CSF dynamics and their potential clinical applications. The discussion offers insights into the optimization of diffusion MRI acquisition parameters to enhance the sensitivity and specificity of diffusion metrics on underlying CSF dynamics. Lastly, we emphasize the importance of cautious interpretations of diffusion‐based imaging, especially when differentiating between tissue‐ and fluid‐related changes or elucidating structural versus functional alterations.
Dynamic optimization of nonlinear differential game problems using orthogonal collocation with analytical sensitivities
Authors: Xiao Long , Liu Miao , Shi Benyun , Liu Ping , Liu Xinggao 
Published: May 2024

AbstractThis article presents an effective computational method based on the orthogonal collocation on finite element for nonlinear pursuit‐evasion differential game problems. The original problems are transformed into two dynamic optimization problems at first, so that the difficulty of obtaining the solution is reduced. To improve the convergence rate and the efficiency, the sensitivities describing the influence of control and interval parameters on state are derived through the discretized dynamic equations for the resulting nonlinear programming problem. The convergence speed is introduced to measure the performance in the upper level iteration. The main structure and the algorithm of the method are also given. Two demonstrative differential game problems with different scenarios from practice are studied. Compared with the approach without sensitivity information, the proposed method needs less function evaluations and saves at least 68.4% of the computational time. The research results show the effectiveness of proposed approach.
Axisymmetric virtual elements for problems of elasticity and plasticity
Authors: Yaw Louie L. 
Published: May 2024

AbstractThe virtual element method (VEM) allows discretization of elasticity and plasticity problems with polygons in 2D and polyhedrals in 3D. The polygons (and polyhedrals) can have an arbitrary number of sides and can be concave or convex. These features, among others, are attractive for meshing complex geometries. However, to the author's knowledge axisymmetric virtual elements have not appeared before in the literature. Hence, in this work a novel first order consistent axisymmetric VEM is applied to problems of elasticity and plasticity. The VEM specific implementation details and adjustments needed to solve axisymmetric simulations are presented. Representative benchmark problems including pressure vessels and circular plates are illustrated. Examples also show that problems of near incompressibility are solved successfully. Consequently, this research demonstrates that the axisymmetric VEM formulation successfully solves certain classes of solid mechanics problems. The work concludes with a discussion of results for the current formulation and future research directions.
A systematic review of in‐person versus remotely delivered interventions for youth with chronic pain

Published: May 2024

AbstractThe COVID‐19 pandemic prompted a rapid shift from in‐person to virtually‐delivered care. Many youth with chronic pain have the ability to access care virtually; however, little is known about the efficacy of pain care for youth with chronic pain delivered virtually when compared to in‐person. Such evidence is essential to guide youth in making decisions about their care, but also to inform what options health professionals present to youth. The purpose of this systematic review and meta‐analysis was to examine the efficacy of interventions that are delivered in‐person versus virtually for youth with chronic pain. Five databases (i.e., CINAHL, EMBASE, MEDLINE, APA PsycINFO, and Web of Science) were searched in October 2022 to identify randomized controlled trials that compare single/multimodal interventions for pediatric chronic pain delivered in‐person versus virtually. A total 3638 unique studies were identified through database and other searching, two of which satisfied established criteria for inclusion in this review. Both studies compared psychological interventions delivered virtually versus in‐person for youth with chronic pain and showed comparable efficacy across modalities. The planned meta‐analyses could not be conducted due to different outcomes within each study that could not be combined. This systematic review highlights a critical gap in the evidence regarding the efficacy of virtually delivered interventions for youth with chronic pain. This evidence is necessary to inform treatment decisions for youth, and further research is required to develop the evidence to inform clinical interventions, especially as virtual treatments continue to be offered.
Direct prostacyclin transition in pediatric patients with pulmonary hypertension

Published: May 2024

AbstractPediatric patients with pulmonary arterial hypertension (PAH) are commonly treated with the prostacyclin analog treprostinil in IV, SQ, inhaled or oral form, or the prostacyclin receptor agonist selexipag. Patients who transition between these medications often follow recommendations for gradual up‐ and down‐titrations that take place over several days in the hospital or several weeks as an outpatient. However, hospital resources are limited, and long transitions are inconvenient for patients and families. We report a case series of eight pediatric patients with PAH transitioned directly between prostacyclins with no overlapping doses. Direct medication transitions occurred in the cardiac intensive care unit (CICU), at home and in cardiology clinic. Equivalent doses for selexipag were estimated using information extrapolated from experience, published materials and selexipag study guidelines. All patients completed direct transition as planned and remained on transition dose for at least 1 week. In most cases selexipag was up‐titrated at home after establishing initial transition dose. In select patients, direct prostacyclin transition in pediatric patients with PAH is safe, effective, convenient for families and reduces the use of hospital resources.

Published: May 2024

AbstractElevated stream temperatures under low‐flows, exacerbated by global warming, are a stressor that affects aquatic species directly or in combination with other stressors. Stream temperatures are influenced by energy fluxes across the air–water interface as well as by hydrological exchange processes occurring at the water–riverbed interface. Small‐scale stream temperature dynamics influenced by exchange flows are still underrepresented in stream temperature research. To investigate high‐resolution temperature dynamics and hydrological exchange processes at the sediment–water interface we applied fiber‐optic distributed temperature sensing (FO‐DTS) at two sites in the mountainous Kinzig catchment combined with mapping and measurement of additional environmental conditions. Two types of temperature anomalies could be observed at one site under conditions of low flow and high air temperature. Dampening effects coincided with riverine features such as pools, vegetation roots, fine sediment, and signs of streambank seepage which indicated hyporheic exchange flows. Increased heating of the substrate during the day was identified in shallow sections where sediment was exposed to the air and shading from riparian vegetation was patchy. At another site, at which the cable could not be buried because of the sediment composition, temperature anomalies in the overlying water indicated diffuse groundwater exfiltration. The results show that small‐scale processes in the hyporheic zone, low water tables, and riparian shading influence stream temperature in mountainous streams and can be identified with FO‐DTS under suitable conditions. The results improve our understanding of stream temperatures (in the hyporheic zone) and provide important information on how to improve hydrological modeling.
