Coexisting Kienböck's and Preiser's Disease of the Wrist: Experience with Proximal Row Carpectomy with Dorsal Capsular Interposition Technique
Authors: Oh Seungbae , Park Hyun Woo , Kang Soo‐Hwan , Lim Dohyung , Park Il‐Jung 
Published: June 2023

BackgroundIdiopathic avascular necrosis of the lunate is known as Kienböck's disease and that of the scaphoid is known as Preiser's disease. Because the prevalence of coexisting Kienböck's and Preiser's diseases is very low, standardized stages of disease and treatments are not established.Case PresentationWe report coexisting avascular necrosis of the scaphoid and lunate in a 68‐year‐old woman with no history of steroids or other risk factors. We treated her with proximal row carpectomy with capsular interposition technique. A distal‐based dorsal capsular flap was prepared and repaired the palmar capsule. At the last follow‐up, she had no pain and had gained improved range of wrist motion. There was no arthritic change at the newly formed radiocapitate joint.ConclusionsIn the case of collapsed lunate and scaphoid with avascular necrosis, the proximal row carpectomy procedure has an advantage. Proximal row carpectomy with dorsal capsular interposition can be performed when the lunate or scaphoid cannot be saved. Arthritic changes of the capitate head and distal radius lunate facet can be covered with the dorsal capsule.

AbstractBackgroundCow's milk allergy (CMA) is one of the most common food allergies world‐wide. The emergence of online CMA symptom questionnaires, aimed at parents and/or healthcare professionals (HCP), may raise awareness about the possible diagnosis of CMA, but also increases the risk for overdiagnosis leading to unnecessary dietary restriction impacting on growth and nutrition. This publication sets out to establish the availability of these CMA symptom questionnaires and critically assesses the development and validity.MethodsThirteen HCP working in the field of CMA, from different countries, were recruited to participate. A combination of a Pubmed and CINAHL literature and online review using the Google search engine in English language was used. Symptoms in the questionnaires were assessed, using the European Academy for Allergy and Clinical Immunology guidelines for food allergy. Following the assessment of both the questionnaires and literature, the authors followed the modified Delphi approach to generate consensus statements.ResultsSix hundred and fifty‐one publications were identified, of which 29 were suitable for inclusion, with 26 being associated with the Cow's Milk‐Related Symptoms Score. The online search yielded 10 available questionnaires: 7/10 were sponsored by formula milk companies and 7/10 were aimed at parents and three at HCP. Following the assessment of data, 19 statements were generated in two rounds of anonymous voting reaching 100% agreement.ConclusionsOnline CMA questionnaires, available to parents and HCP's, are varied in symptoms, and most were not validated. The overarching consensus generated from authors is that these questionnaires should not be used without the involvement of HCP.

Published: June 2023

AbstractBackgroundMutations in the TTN gene, encoding the muscle filament titin, are a major cause of inherited dilated cardiomyopathy. Early‐onset skeletal muscle disorders due to recessive TTN mutations have recently been described, sometimes associated with cardiomyopathies.Case DescriptionWe report the case of a boy with congenital core myopathy due to compound heterozygosity for TTN variants. He presented in infancy with rapidly evolving restrictive cardiomyopathy, requiring heart transplantation at the age of 5 years with favorable long‐term cardiac and neuromuscular outcome.ConclusionHeart transplantation may have a role in selected patients with TTN‐related congenital myopathy with disproportionally severe cardiac presentation compared to skeletal and respiratory muscle involvement.
From noise to knowledge: Improving evidentiary standards for program efficacy to better inform public policy and management decisions

Published: June 2023

AbstractCurrent approaches employed by U.S.‐based clearinghouses to rate the efficacy of interventions to address social problems typically do not result in sufficient information to help practitioners. Current standards of evidence employed across the United States apply a positivist notion of validity with quantitative research criteria that discourage answering importanthowandwhyquestions, explicitly privilege quantitative/RCT evidence, offer few contextual insights, and rarely discuss disparities in outcomes across participants differing by race, gender, and ethnicity. We offer a set of standards of evidence to assess qualitative and mixed methods studies, as well as RCTs and quasi‐experimental designs, and probe the extent to which the studies address context and equity. We applied our proposed new standards of evidence to all intervention studies rated as the highest quality by the What Works Clearinghouse (WWC) sponsored by the U.S. Department of Education from 2017 to 2021 to demonstrate the usefulness of our standards.
The formation of schwertmannite colloids and natural remediation of toxic elements from Shojin River, Hokkaido, Japan

Published: June 2023

AbstractPassive treatment systems are a sustainable solution to mine drainage remediation, however, clarity lacks in the detailed understanding of the geochemical processes that govern the remediation processes. A study was carried out at Shojin River in Southwest Hokkaido, Japan, which has an acidic pH and is high in Fe, to represent the principal processes that occur in mine drainages of similar characteristics. At Shojin, Fe and S were mined from the Shojingawa mine, after which, wastewater contaminated by toxic elements such as Fe, As and Pb continue to flow from the underground. This wastewater flows through industrial and fishing areas, hence ensuring that the water meets environmental standards is important. In particular, the role of colloidal materials in transporting the toxic elements was investigated by analyzing the distribution of the elements (Fe, As and Pb) in the drainage as the dissolved and colloidal fractions, obtained from micro‐, and ultrafiltration respectively. Iron, particularly schwertmannite colloid formation was observed in the Shojin River system. Itwas present in the dissolved fraction in the wastewater like As, but after mixing with the uncontaminated river water, Fe in the colloid fraction gradually increased toward the downstream. Arsenic trends are similar to those of iron, indicating efficient sequestration by the schwertmannite colloids. Lead is dominantly in the dissolved fraction throughout the drainage and is comparatively less sequestered due to competitive adsorption with As and its pH dependence to be efficiently adsorbed. A detailed observation of the concentration trends suggests that pH 3.1 may efficiently allow colloid formation and subsequently, toxic element sequestration. The behavior of Fe colloids in Shojin River was compared to those of a circum‐neutral drainage system (Ainai mine drainage). The formation of the colloids in the acidic system was limited by the pH range, while colloids formed faster and more abundantly in the circumneutral system. The acidic and circum‐neutral systems are abundant in schwertmannite and ferrihydrite colloids respectively. The colloids in both systems were transported after their formation, however, the colloids in the Shojin (acidic) system were transported further than those of the circumneutral system. Aggregation is observed in both systems which results in a deposition of the colloid aggregates and hence an efficient removal of Fe and As, and minimally, Pb from the mine drainages.
Epistemic uncertainty in catastrophe models—A base level examination
Authors: Born Patricia , Dumm Randy , Johnson Mark E. 
Published: June 2023

AbstractIn this paper, we evaluate sources of variation in the output from catastrophe models with emphasis on the epistemic uncertainty in modeled expected losses. Using building data from the 34 buildings that comprised the California Northridge campus at the time of the Northridge earthquake, we explore the sensitivity of estimated average annual losses obtained from a cat model to the quality of model input. Namely, we consider how changes in four key model assumptions—building locations, building height, construction type, and the event catalog—affect cat model loss estimates. We find that accurate information on some input variables is critical (e.g., all steel construction) and the interaction between input variables should not be discounted. Our results have important implications for insurer decisions that are informed by the output of catastrophe models—product pricing, portfolio diversification and underwriting decisions, negotiations and discussions with regulators and similar activities with capital market participants. The financial impact of improving data quality and targeting data related to key model inputs for that insurer when at scale is not trivial. As such, this paper provides an impetus for establishing and improving benchmarks for model inputs.
Victor Pelevin and Eurasianist Geopolitics
Authors: Filimonova Tatiana 
Published: June 2023

AbstractThe first decades of Victor Pelevin’s writing coincided with the burst in popularity of neo‐Eurasianist and neo‐imperialist ideas. This paper traces the various forms that Pelevin’s treatment of civilizational and geopolitically focused ideologies has taken over the course of his career. His preoccupation with these ideas ranges from inconspicuous reflection of the Eurasian phenomenon to Eurasianism’s intensifying critique, and, eventually, to a more comprehensive engagement with concepts of classical geopolitics. If early on Pelevin’s portrayal of neo‐imperialists and their ideas has been largely satirical (Empire V, 2006), in the 2010s his texts began to demonstrate a deeper entanglement in civilizational thought and expression of a geopolitical worldview. “Operation ‘Burning Bush’” (2010), S.N.U.F.F. (2012), and Batman Apollo (2013), while maintaining a satirical take on aspects of the neo‐imperialist worldview, reveal the author’s internalized perception of the world as a stage for the clash of civilizations, and Pelevin’s seemingly growing conservatism. Ultimately, as postmodernist tendencies become common in the political sphere, Pelevin again blends the esoteric and the political by bringing Eurasianist noospherism into “The Art of Light Touches” (2019), lending a metaphysical angle to the antagonism between Russia and the West, and demonstrating how fiction can penetrate public discourse and vice versa.
Do tax subsidies for retirement saving affect total private saving? New evidence on middle‐income workers*
Authors: Christensen Camilla Skovbo , Ellegaard Bastian Emil 
Published: June 2023

AbstractWe exploit exogenous variation from a pension reform in Denmark to estimate the effect of tax subsidies on total private saving. We present new evidence on individuals in the middle of the income distribution and show that a reduction in tax subsidies for retirement saving reduces total private saving. The reform changed the tax incentives for saving in the pension scheme that holds the highest tax advantage for middle‐income workers in Denmark. We find that for each unit of reduced saving in this pension scheme, only 64 percent is substituted to other types of saving.
Emerging modes of digitalisation in the delivery of welfare‐to‐work: Implications for street‐level discretion
Authors: Ball Sarah , McGann Michael , Nguyen Phuc , Considine Mark 
Published: June 2023

AbstractCountries are increasingly looking to ‘digitalise’ how public services are delivered, with welfare‐to‐work and public employment services being key sites of reform. It is hoped that digitalisation can achieve efficient, effective, and targeted services for those in need and there is now a growing body of research on both the opportunities and pitfalls associated with this transition to digital welfare states. However, as a concept, ‘digitalisation’ remains ambiguously defined, hindering understanding of the distinct ways that discrete technological innovations are reshaping citizens' access to social protection and the role of street‐level discretion in welfare administration. Drawing on interviews with expert informants from three countries pioneering digital reforms, this study aims to better understand what digitalisation entails for the delivery of activation. We identify three discrete modes of ‘digitalisation’ in welfare‐to‐work programmes: virtual engagement (remote activation), transactional automation (self‐activation), and digital triaging (targeted activation). Far from digitalisation heralding the automation and curtailment of frontline discretion, the different modes reshape frontline delivery and citizens' access to social protection in specific ways.
Whatever happened to the Child Trust Fund? The abandonment of universal savings for UK children
Authors: McKay S. , Tian L. , Lymer A. 
Published: June 2023

AbstractChild development accounts (CDAs) provide subsidised savings accounts for children to help meet life course needs. While now largely forgotten, the Child Trust Fund was an innovative savings scheme for UK children that sought to generate a capital sum when they turned 18. The first children to receive these funds reached this point in late 2020 so it is timely to review the impact of this national scheme, which by 2022 had £10 bn saved in it. We consider how far the Child Trust Fund led to higher levels of savings for those children who were eligible for it and whether there is any evidence it created a savings habit in young people and their parents. We use six waves of longitudinal ONS Wealth and Assets Survey data. While we find a small effect on savings, with children from better‐off families benefiting the most, there is little evidence of a meaningful effect on savings habits. Nonetheless, the policy's impact on generating even small amounts of savings could be important, especially as most children in the UK have no savings. The study offers policy recommendations to support children's savings in the UK, based on the significant example of asset‐based welfare policy that the CTF provides.

Effects of Incremental Changes to Frame Mass on Manual Wheelchair Propulsion Cost
Authors: Misch Jacob , Sprigle Stephen 
Published: June 2023

Abstract
The objective of this study was to assess the effects of small, incremental additions to wheelchair frame mass (0 kg, +2 kg, and +4 kg) on the mechanical propulsion characteristics in both straight and curvilinear maneuvers. A robotic propulsion system was used to propel a manual wheelchair over a smooth tiled surface following rectilinear (“Straight”) and curvilinear (“Slalom”) trajectories. Three unique loading conditions were tested. Propulsion costs and system rolling resistance estimations were empirically collected using the robotic wheelchair tester. Propulsion cost values were equivalent across all loading conditions over the Slalom trajectory. In the Straight trajectory, adding 2 kg on the axle had equivalent propulsion cost to the unloaded configuration. Adding 4 kg on axle was comparable, but not equivalent, to the unloaded configuration with small (≤4.1%) increases in propulsion cost. This study demonstrates that small (0–4 kg) changes to the frame mass have no meaningful impacts on the propulsion characteristics of the manual wheelchair system. Differences in propulsion cost and rolling resistance were detectable but contextually insignificant.
Well Test Analysis for a Well in Gas Storage Reservoirs With the Formation Containing High Salinity Water

Published: June 2023

Abstract
The production capacity of the gas wells is seriously affected by salt deposition during the injection and production process for underground gas storage with high salt content, so it is necessary to predict the production performance through well test technology. However, the existing well test analysis methods cannot be reliably used to interpret the well test data affected by salt deposition phase change and high-speed non-Darcy flow during the injection and production process. Therefore, this paper first determines the relationship between salt deposition and temperature and pressure through flash calculation of phase equilibrium of saltwater and hydrocarbon system, then establishes a porosity and permeability model considering the effect of salt deposition, and further establishes a high-speed injection-production well test analysis model considering the effect of salt deposition in combination with Forchheimer’s percolation law. Finally, the model is solved by numerical method, and the dynamic changes of reservoir pressure and salt deposition are simulated and calculated. The results show that the higher the salinity of formation water is, the greater the risk of salt deposition in the reservoir is, and the permeability of the reservoir will significantly decrease after salt deposition occurs; the non-Darcy flow effect will aggravate the risk of salt deposition in the reservoir. The research results provide a theoretical method for the evaluation of reservoir parameters and production performance prediction of salt gas storage reservoirs.

Purpose: The potential impact of hormonal contraceptives (HCs) on player health and performance in women’s rugby union (rugby) is not well understood, despite rugby’s growing popularity worldwide. This study investigated the prevalence of HC use and reported associations with training and performance in a global sample of women rugby players. Method: A globally distributed online survey, seeking to explore experiences in women’s rugby, was completed by 1596 current or former adult women 7s or 15s rugby players (mean age 27 [6] y; 7 [5] y playing experience) from 62 countries. The survey included a section of questions about reported HC use, including the type, reason for use, symptoms, and experiences relating to rugby training and performance. Results: A total of 606 (38%) participants from 33 of the 62 (53%) countries reported using HCs, with the combined oral contraceptive pill reported as the most frequently used (44%). Almost half of participants using HCs (43%) tracked HC-related symptoms. Over 10% reported altered rugby performance due to HC-related symptoms, 22% required medication to manage symptoms, and 11% used HCs to control or stop their menstrual periods for rugby training and performance. Conclusions: The current study highlights the prevalence of HC use in women’s rugby, identifying practices that may negatively affect performance, health, and well-being. Thus, there is an urgent need to better understand the motivations for such practices and knowledge of potential side effects among women rugby players across all levels and countries.
Association between Triglyceride-Glucose Index and carotid plaque in Japanese population: a cross-sectional study
Authors: Liu Jiuling , Ye Min , Wang Yuanwei 
Published: June 2023

ObjectivePrevious studies linking Triglyceride Glucose (TyG) Index to carotid plaque have yielded inconsistent results. Moreover, related studies on the population of Japan are rare. This study aims to provide further results.DesignA hospital-based cross-sectional study.SettingThe Shin Takeo Hospital.ParticipantsWe assessed 1904 Japanese participants (988 men and 916 women) whose mean age was 57±11.9 years, and those participants underwent health check-ups at Shinbuf Hospital at Shin Takeo Hospital from 1 April 2016 to 31 October 2017.MethodologyCarotid plaque, triglyceride and fasting glucose and other relevant indicators were collected. We used ultrasonography to evaluate carotid plaque. A multivariable logistic regression model and generalised additive model were used to evaluate the association between the TyG Index and carotid plaque. Subgroup and interaction analyses were validated for the consistency of these correlations.ResultsFollowing the adjustment of traditional carotid plaque risk factors, the non-linear relationship between the TyG Index and carotid plaque was investigated. Using a two-piecewise regression model, we calculated the inflection point to be 9.06. The OR and 95% CIs for the inflection points on the left and right sides were 1.70 (1.27 to 2.29) and 0.88 (0.52 to 1.47), respectively. According to the variables tested, the interactions between the TyG Index and all subgroup factors were analysed and significant interactions were not observed.ConclusionIn individuals who underwent a comprehensive check-up in Japan, the relationship between the TyG Index and carotid plaque is non-linear. When the TyG Index is less than 9.06, it is associated with carotid plaque.
