OBJECTIVES
Data on US caregiver perceptions on coronavirus disease 2019 (COVID-19) and COVID-19 vaccination are limited. We identified trends in and associations with COVID-19 vaccine hesitancy in caregivers of hospitalized children.

METHODS
Cross-sectional surveys on pediatric COVID-19 disease and vaccine attitudes, behaviors, and beliefs were administered across study years (December 8, 2020–April 5, 2021, November 30, 2021–March 15, 2022, and October 26, 2022–March 15, 2023). English and Spanish-speaking caregivers of hospitalized children ages 6 months to 11 years were included. General vaccine hesitancy was assessed using the Parent Attitudes about Childhood Vaccines survey.

RESULTS
Of 1268 caregivers from diverse backgrounds, one-third vaccinated or intended to vaccinate their child. Half endorsed fear of their child receiving the COVID-19 vaccine and were concerned the vaccine was new. Over time, more believed “the COVID-19 vaccine does not work” and fewer agreed “children who are otherwise healthy can die from COVID-19.” Study season (2022–2023), older child age, higher income, child receipt of influenza vaccine, caregiver receipt of COVID-19 vaccine, and not being worried about vaccine novelty were positively associated with child vaccination. Intent to vaccinate was negatively associated with study season (2022–2023), Parent Attitudes about Childhood Vaccines score ≥50, lack of child influenza and caregiver COVID-19 vaccination, lack of fear of their child “getting COVID-19” and being “worried that the COVID-19 vaccine is new.” The majority who intended to vaccinate were willing to immunize before discharge.

CONCLUSIONS
Vaccine novelty and perceived lack of need were associated with refusal. Caregiver COVID-19 and child influenza vaccine acceptance were positively associated with COVID-19 vaccine acceptance. The inpatient setting offers the opportunity to improve vaccine uptake.

OBJECTIVE
Hospitalized children are a potentially underimmunized population. We sought to determine the proportion of patients admitted to our pediatric medicine inpatient units who are underimmunized or unimmunized and to identify barriers to immunization faced by families of children admitted to hospital.

METHODS
We conducted a prospective study of children aged 2 months to 18 years admitted to our pediatric medicine inpatient units between July 2021 and October 2022. Immunization and demographic data were collected from electronic medical charts. Immunization status of each child was categorized as up-to-date if they had received all eligible vaccine doses in accordance with the provincial immunization schedule. Caregivers completed a survey on barriers to immunizations; results were compared between caregivers of children whose vaccines were up-to-date and those who were not.

RESULTS
Hospitalized children were missing more doses of the preschool vaccines than the general population based on published provincial data. Only 142 of 244 (58.2%) of study patients were up-to-date on all their immunizations. Caregivers of children whose immunizations were not up-to-date reported significantly more barriers to vaccination in all survey categories: access to shots, concerns about shots, and importance of shots.

CONCLUSIONS
There is a disparity in immunization status between children admitted to hospital in a Canadian setting compared with national targets and community immunization rates. Caregivers of underimmunized hospitalized children cited significantly more barriers to immunization when compared with hospitalized children who are up-to-date. Pursuing a hospital-based immunization strategy could lead to improved immunization status for hospitalized children.

Published: August 2024

La pandemia causada por el Covid-19 implicó un cambio abrupto de la modalidad presencial a la educación remota de emergencia (ERT). El objetivo de este artículo es describir las experiencias pedagógicas y las acciones políticas que tuvieron una profesora y un profesor de inglés durante los tiempos de pandemia en una universidad pública. Al seguir los principios de la investigación cualitativa, se llevó a cabo un estudio de caso descriptivo. Durante la instrucción se realizaron actividades pedagógicas que incluyeron la presencia social que involucró respuestas cohesivas (saludos, formas de tratamiento), respuestas afectivas (sentimientos, emociones) y respuestas interactivas (reconocimiento, aprobación). Como sujetos políticos, el profesorado fue apoyo, guía y consejero del estudiantado con necesidades especiales. También, establecieron acuerdos con el estudiantado, fueron flexibles con las evaluaciones y remitieron al estudiantado al bienestar universitario. Finalmente, se concluye que la tarea del profesorado en cada encuentro pedagógico, además de formar al estudiantado en un área específica, corresponde también promover una educación crítica que le brinde al estudiantado los elementos necesarios para ejercer el poder sobre sus vidas.

Authors: Rejido Sánchez Giselle , Álvarez Iriarte Claudia 
Published: August 2024

El objetivo del estudio es evaluar el registro discursivo de docentes de la II región de Antofagasta, Chile, en relación con el autocuidado del profesorado, para contribuir al diseño de estrategias eficaces que promuevan la salud mental y el bienestar en los establecimientos educacionales. La propuesta consideró un diseño de investigación fenomenológico-hermenéutico, bajo un enfoque metodológico cualitativo que incluyó la participación de 420 docentes del sistema escolar regional.
Los instrumentos de recogida de información incluyeron la encuesta de pregunta abierta y el registro documental. El análisis discursivo se efectuó a través de la categorización y codificación de la información obtenida, por medio de la lógica inductiva. Respecto de los resultados, el discurso docente se inclina hacia una lógica de recreación más que al autocuidado, lo cual omite prácticas que tributen a una atención integral. En el ámbito emocional, se advierte la ausencia de prácticas que fortalezcan la reflexión personal, la autopercepción o la gestión emocional. En cuanto al ámbito social, se enfatiza la importancia de cultivar las relaciones sociales, mientras fortalecen la conexión profunda con su ser interior. Es crucial señalar que un número significativo reveló no efectuar actividades de autocuidado o no saber identificarlas. Se suma a lo anterior la confirmación de que ninguna de las unidades educativas cuenta con la sistematización de prácticas que promuevan el cuidado preventivo de su salud mental. En cuanto al análisis documental, las propuestas se inclinan hacia la dimensión emocional como el eje central que sustenta el cuidado de la salud mental. A modo de conclusión, se advierte la necesidad de que las unidades educativas diseñen, ejecuten y sistematicen estrategias para atender, concientizar y apoyar a los y las profesionales de la educación. Asimismo, el estudio proyecta la ampliación a nuevas líneas de investigación con miras a analizar la viabilidad de las propuestas con foco territorial, evaluando y adecuando la ejecución de los planes de trabajo centrados en el cuidado de la salud mental del grupo participante y su impacto en la promoción del autocuidado en beneficio de la mejora continua de los ambientes educativos propicios.

Key Points

Common kidney stones are unlikely to be an independent and direct cause of CKD in the general population.CKD may protect against kidney stones because of changes in key urinary factors critical for stone formation.

Background
Kidney stones and CKD are common disorders with a substantial interaction. Although observational studies have suggested a potential for enhanced CKD risk after prior kidney stones, the exact relationship remains ambiguous.

Methods
Shared comorbidities between two diseases were identified using unbiased screening. Genome-wide association study summary statistics were obtained from the UK Biobank (UKBB), FinnGen, and CKDGen, followed by genetic association analyses across various traits. Bidirectional Mendelian randomization (MR) analyses were performed to define causal links, complemented by multivariable MR that included the shared comorbidities including hypertension, diabetes, and obesity. Observational analyses were undertaken using cohorts from the Mayo Clinic and a UKBB subset.

Results
Despite identifying a total of 123 conditions as shared comorbidities, there was no significant genetic correlation between kidney stones and CKD. Unadjusted MR analysis revealed no significant association between kidney stones and CKD risk (UKBB [exposure]/FinnGen [outcome]: odds ratio [OR]=0.97, 95% confidence interval [CI], 0.88 to 1.06; FinnGen/UKBB: OR=1.17, 95% CI, 0.98 to 1.39). Kidney stones did significantly associate with a higher urinary albumin-creatinine ratio (β=0.014, 95% CI, 0.002 to –0.025), but this association disappeared in the multivariable MR model (β=0.009, 95% CI, −0.003 to 0.020). Furthermore, in a cross-sectional analysis limited to the UKBB cohort, a robust regression model did not detect an independent association between kidney stones and urinary albumin-creatinine ratio (β=0.16, 95% CI, −0.04 to 0.35) or eGFR (β=0.10, 95% CI, −0.07 to 0.28). Conversely, CKD associated with a diminished risk of kidney stones in multivariable MR models (UKBB/FinnGen: OR=0.77, 95% CI, 0.69 to 0.87; FinnGen/UKBB: OR=0.73, 95% CI, 0.66 to 0.81). Furthermore, in the Mayo Clinic cohort with available urinary biochemistries, lower eGFR was associated with lower urinary calcium excretion and urinary calcium oxalate/phosphate supersaturation.

Conclusions
In this study, kidney stones were not independently associated with CKD. Conversely, CKD was associated with a lower risk of calcium kidney stones likely via changes in key urinary traits, including lower calcium excretion.

INTRODUÇÃO: A estimulação sensório-motora (ESM) é uma intervenção precoce utilizada em recém-nascidos (RN) para a organização de seus sistemas. O fisioterapeuta que faz uso da ESM deve ter um olhar cuidadoso para os sinais apresentados pelos RN após os procedimentos. OBJETIVO: Analisar a percepção de fisioterapeutas sobre alterações do sistema autônomo e do estado comportamental de RN após procedimentos de ESM. MÉTODOS: Estudo transversal realizado com fisioterapeutas atuantes em unidades neonatais. Os dados foram coletados por questionário eletrônico, processados no programa SPSS (versão 21.0) e apresentados em frequência absoluta (n) e relativa (%). RESULTADOS: Participaram deste estudo 72 fisioterapeutas, 48,6% possuíam título de especialista, 63,9% atuavam em Unidade de Terapia Intensiva Neonatal, 38,8% residiam na região sul e 38,8% na região sudeste do Brasil. A percepção da maioria dos fisioterapeutas após procedimentos de ordem tátil foi estabilidade ou diminuição da frequência cardíaca (FC) e respiratória (FR), e estabilidade da saturação de oxigênio (SpO2), e após procedimentos de ordem vestibular foi estabilidade da FC, FR e SpO2. Houve percepção de sono ativo, sonolência e alerta ativo após todos os procedimentos de ordem tátil e vestibular. O alerta ativo foi percebido após todos os procedimentos e o choro intenso não foi percebido. CONCLUSÃO: Do sistema autônomo, a maioria dos fisioterapeutas perceberam a FC e FR estáveis ou diminuídas e SpO2 estável ou aumentada após os procedimentos de ESM. Do estado comportamental, o alerta ativo foi percebido com maior frequência entre os fisioterapeutas.

Published: August 2024

Zur Senkung der Emissionen im Straßenverkehr gewinnt der batterieelektrische Antriebsstrang nicht zuletzt aufgrund seiner hohen Effizienz zunehmend an Bedeutung. Deshalb rückt auch die Optimierung des Bordnetzes, das die Nebenverbraucher versorgt, in den Fokus der Entwicklung. Dessen Anteil am Gesamtverbrauch ist aufgrund des stetig zunehmenden Umfangs an Komfortfunktionen im Fahrzeug messbar signifikant für die Gesamteffizienz. Da die Energieversorgung der Nebenverbraucher im Bordnetz zusammen mit der kommunikativen Vernetzung der Komponenten ein komplexes System bildet, ist die Erlangung des für die Optimierung nötigen Systemverständnisses nicht trivial. Deshalb wird eine datenbasierte Methodik vorgeschlagen, mit der das Stromverbrauchsverhalten einzelner Verbraucher im Bordnetz anhand deren Kommunikation mit anderen Verbrauchern modelliert wird. Anschließend werden die Modelle durch den Einsatz ausgewählter Methoden der erklärbaren Künstlichen Intelligenz (Explainable AI, XAI) plausibilisiert. Zusätzlich wird eine Studie zur Anwendung einzelner globaler, sowie lokaler XAI-Methoden, die mit potenziellen Nutzern im entsprechenden Fachgebiet eines Automobilherstellers durchgeführt wurde, vorgestellt und interpretiert.
Automatische Partitionierung für die virtuelle Inbetriebnahme
Authors: Littfinski Daniel , Klingel Lars , Verl Alexander 
Published: August 2024

Die wachsenden Anforderungen an die Automatisierung von Produktionssystemen und -prozessen erfordern eine verstärkte virtuelle Absicherung, um eine effiziente Produktion zu gewährleisten. Eine etablierte Methode hierfür ist die virtuelle Inbetriebnahme (VIBN). Die dadurch steigende Komplexität der Simulationsmodelle von Produktionssystemen führt zu erhöhtem Rechenaufwand und längeren Simulationszykluszeiten. Die Aufteilung eines Simulationsmodells in einzelne Partitionen ist ein zeitintensiver Prozess, der zudem eine hohe Fehleranfälligkeit aufweist. Effizientere und intelligente Methoden zur Partitionierung von Simulationsberechnungen sind deshalb unerlässlich, um den Anforderungen an Echtzeit-Simulationen in der VIBN und dem erhöhten Berechnungsaufwand gerecht zu werden. In diesem Beitrag wird ein Konzept dafür vorgestellt.
Optimizing Gas-Flaring Solutions: Enabling Enhanced Oil Recovery and Power Generation
Authors: Gracian L. A. , Arguello I. M. , Diyashev I. R. 
Published: August 2024

Abstract
Produced gas is currently being flared into the atmosphere due to the lack of infrastructure to transport and sell the gas. We can re-inject this gas back into the formation, increasing the reservoir pressure and making the oil lighter thus enabling enhanced oil recovery. Additionally, the gas can be used to generate electricity during the highest energy demand times of the year to help stabilize grid usage. Prices would be monitored using real-time data provided by ERCOT to allow for rapid responses to changes in demand. There is a threefold benefit to this process: enhanced oil recovery, electricity generation, and a reduction in flared gas.
Following prior work in the Wolfcamp formation (SPE 213002), we looked at four additional unconventional formations in Texas: Spraberry, Bone Spring, Austin Chalk, and Eagle Ford. Each formation had reservoir properties taken from published SPE literature to build a single well simulation model. Each model was tested using a cyclic gas injection schedule. The schedule consisted of three months producing, two months injecting, and one month of soaking. Three different gas injection rates were used to compare the additional incremental oil production for each case. The cases simulated were 1.5 MMscf/D, 3 MMscf/D, and 5 MMscf/D.
Multiple economic evaluations were run to estimate the potential cashflow of the project in each formation. Assuming a gas engine with generator package costs $0.5 million, compressor $2 million, and a gearbox $0.3 million. The total cost of the project would be approximately $2.8 million. Assuming the current oil and gas prices of $80 and $2.75 respectively we estimate a return on investment of 2-3 years with additional oil production ranging from 30-80% based on the specific reservoir formation.
Water Sourcing Reliability, Cost, and Circularity for Low Carbon Hydrogen Development

Published: August 2024

Abstract
Clean hydrogen will require significant volumes of water given the high production targets in certain geographic locations, regardless of generation pathway, i.e., from an electrolyzer or natural gas-based process with carbon capture and sequestration (CCS). Therefore, reliable water sourcing related to the planned infrastructure's location is a critical input that needs to be considered in the early project planning stages. This paper will review the potential sources of water and costs associated with incorporating them within the hydrogen supply chain and will explore the respective attributes of alternatives.
Water demand will vary between different hydrogen production methods, site locations, and project specific facility designs. Furthermore, the cost of water will vary as well depending on the source water's respective quality, facilities, water conveyance, treatment, and waste disposal requirements.
For the energy industry, water for hydrogen production has become as important as natural gas for its processes and as important as crude oil has been for its refineries. Project viability depends on the long-term reliable access to the selected water source, forcing project siting to be a critical project consideration.
Additionally, water treatment processes vary according to the source's base purity and contaminants. Subsequently, these processes create waste streams with concentrated impurities, which may have to be mitigated prior to disposal.
We will provide the readers with awareness of the issues related to water sourcing options and considerations, conveyance, and rough order of magnitude (ROM) costs for water infrastructure, including treatment. The clarification of costs associated with different water sources used for hydrogen generation will allow project developers to make more informed decisions. Water sourcing should be a topic at the forefront of planning stages related to hydrogen production. The authors for this paper wish to provide a better understanding of costs related to different options.
Additionally, the implementation of circularity will be analyzed by considering recycled wastewater as the water source for a hydrogen plant. This could reduce the regional disparity in clean energy production and lessen the burden on fresh water supplies.
Accelerated Calibration and CO2 Plume Tracking at the Illinois Basin Decatur Project: A Dynamic Mode Decomposition and Data Assimilation Approach

Published: August 2024

Abstract
Addressing climate change through carbon capture and storage (CCS) technologies necessitates advanced computational methodologies for subsurface CO2 storage monitoring. This study focuses on the Illinois Basin Decatur Project (IBDP), a CCS demonstration pilot aimed at CO2 injection into a deep saline reservoir. We introduce a novel framework combining Dynamic Mode Decomposition (DMD), a data-driven model reduction technique, with direct data assimilation to streamline the calibration of CO2 plume evolution models. This approach enhances rapid tracking and overcomes the computational challenges of traditional high-fidelity numerical reservoir simulations known as the full-order model (FOM).
Using DMD, we analyzed five distinct FOM simulation cases of the IBDP with varied permeability in the Mt. Simon section to develop reduced-order models (ROMs). These ROMs utilize three state variables: reservoir pressure, CO2 plume saturation, and bottom-hole pressure (BHP) from a CO2 injection well alongside multi-level pressures from a monitoring well derived from the FOM and the actual field data respectively. Initial FOM simulation cases assessed the impact of permeability multipliers on pressure responses. We then transformed these into ROMs using DMD, preserving essential dynamics. Linear interpolation between permeabilities and DMD outputs—modes and eigenvalues—established relationships for rapid BHP prediction under different scenarios. Employing a Kalman filter, we optimized a global permeability multiplier, using the ROMs, to align measured and simulated BHP values, ensuring model calibration. The final calibrated FOM was further decomposed to a DMD-based ROM, enabling quick, accurate predictions, significantly reducing computational time from hours to minutes.
Utilizing an ROM derived through DMD, we achieved an order of 160 reduction in computational time (from 8 hours to just 3 minutes) for a 3-year historical CO2 injection period modeled with 547,000 cells of the FOM. The ROM demonstrated remarkable fidelity, with a mean absolute error of 1.46 psi for pressure and 3.7e-05 for CO2 plume saturation, effectively capturing the dynamics of the full-order model. This substantial decrease in computational time illustrates an advantageous trade-off between speed and accuracy, optimizing the potential for long-term forecasting and monitoring of CO2 sequestration.
Incorporating the IBDP as a case study, this research contributes a significant advancement to reservoir simulation practices, offering a potent, efficient tool for CCS monitoring. By integrating DMD for ROM construction with precise data assimilation-based calibration, the study provides a comprehensive solution for swift and accurate subsurface CO2 plume tracking, essential for the successful implementation of CCS projects and the broader effort to mitigate climate change impacts.
