Multifaceted concussion assessment battery: sensitivity at the expense of specificity?

ABSTRACT Objectives A multifaceted assessment battery is recommended for testing suspected concussed athletes; however, the individual tests have limitations and potentially may lead to false positive outcomes. Therefore, the purpose of this study was to psychometrically evaluate concussion assessment tools used for intercollegiate student-athletes, with a focus on the time interval between baseline and subsequent assessments. Methods 92 collegiate student-athletes matched between concussion (N = 46. F32/M14) and non-concussion (N = 46, 32F/14 M) completed the standard assessment of concussion, balance error scoring system, symptom questionnaire, and computerized neurocognitive tests at baseline and acutely (<48 hours) following a concussion. Test outcomes were compared between time points with three approaches, 1) vs baseline, 2) reliable change scores (RCI), and 3) vs American College of Rehabilitation Medicine (ACRM). Concussion assessment sensitivity, specificity, likelihood ratios, predictive values, and diagnostic odds ratio were calculated. A receiver operator characteristic compared area under the curve (AUC) for the overall battery as well as between academic years. Results The sensitivity of the battery was high (78.3 – 95.7%), but specificity was low to moderate (6.5 – 52.2%) with comparison to the RCI typically performing best. The three approaches yielded AUC values between 0.51 – 0.63 which is below the discriminatory threshold (0.70) with comparison to RCI performing best. By academic year, Juniors was the only year in which the ROC exceeded the threshold (0.75). The number of tests failed did not improve any AUC values (0.51 – 0.69) to exceed the threshold. Conclusions The outcomes of this study support the premise that concussion must be evaluated using a comprehensive clinical examination including a variety of assessments to evaluate each clinical domain. Clinicians need to recognize that the multifaceted assessment battery has high sensitivity, but the overall psychometrics do not exceed the threshold for group discrimination and caution must be used in their interpretation.

Parental attitudes and experiences in pursuing genetic testing for their child's motor speech disorder.

Rare and typically severe motor speech disorders such as childhood apraxia of speech (CAS) and dysarthria affect about 1 in 1000 children. The genetic basis of these speech disorders is well-documented, with approximately 30% of children who undergo genomic testing receiving an explanatory genetic diagnosis. As more children with speech disorders are offered genetic testing, understanding parental views and experiences around genetic testing for their child is critical in providing effective pre- and post-test genetic counselling. This research explored parental attitudes, experiences, and perceived implications of pursuing genetic testing for their child with motor speech disorder. Semi-structured interviews were conducted with 20 parents of children with CAS or dysarthria who had undergone exome sequencing. Eight parents had received a genetic diagnosis for their child and 12 received uninformative genetic test results. Interviews were transcribed verbatim, co-coded, and analysed using reflexive thematic analysis. Parents were highly motivated to pursue genetic testing for their child's speech disorder due to the perceived personal, clinical, social, and financial utility in obtaining a genetic diagnosis. Regardless of testing outcome, parents experienced complex emotional responses in receiving their child's genetic test results. Parents whose child received a genetic diagnosis reported improved access to funding and clinical care; however, they also hoped for ongoing informational, clinical, and peer support in navigating the uncertainty surrounding their child's rare diagnosis. Conversely, parents who received uninformative genetic test results reported finding meaning in this test outcome, and used emotional-focused and problem-focused strategies to cope with their child's continued diagnostic odyssey.

Miniaturize the Redox Flow Battery for Accelerated Materials Discovery and Development

Abstract Redox flow batteries are a promising technology for grid-scale energy storage. The aqueous organic redox flow battery is of particular interest for its potentially low material cost and sustainability. Developing novel organic active material for flow battery electrolytes typically entails molecular engineering toward desired properties, necessitating organic synthesis. In a research laboratory setting, the synthesis of specifically designed organic molecules featuring targeted functional groups is time and resources intensive. In the past, synthesizing materials required for battery testing has often required gram-scale production, presenting considerable constraints on the pace of novel organic material discovery. In this report, we introduce a miniaturized cell design that mandates only milligram-scale material synthesis while yielding testing outcomes equivalent or superior to those reported with other commercially available or homemade flow cells in the literature. The test results under various pH conditions validate the scale-down strategy to accelerate the flow battery material discovery and development using the newly designed mini cell. This approach offers researchers an efficient means to notably reduce the time and resource required to develop novel materials for flow batteries.

Neglecting Transparency in the Qur'an Recitation Test for Legislative Candidates in Aceh

This research examines the neglect of the principle of transparency in Qur'an literacy tests for legislative candidates in Aceh, which has hindered voters from making informed decisions. It explores two key questions: What forms does the neglect of transparency take in the Qur'an literacy test for legislative candidates in Aceh? And what are the causes and impacts of this neglect? The findings reveal that the neglect of transparency occurs in two primary forms: first, the establishment of subjective score standards, and second, the refusal of the Independent Electoral Commission (KIP) Aceh to publicly announce the test results. This issue arises from the absence of regulatory mechanisms that would require KIP Aceh to disclose the test outcomes and from the closed process by which the score standards are determined in collaboration with the Qur'an Reading Test Team. The impact of this neglect is the limited public access to vital information needed to elect legislators with religious competence, a quality of significant importance in Aceh, where religious knowledge plays a key role in qualifying individuals for public office.

Clinical implementation of Nephrologist-led Genomic Testing for Glomerular Diseases in Singapore: Rationale and Protocol.

Introduction The early diagnosis and appropriate treatment of monogenic glomerular diseases can reduce kidney failure, avoid unnecessary investigations such as kidney biopsies and ineffective treatment with immunosuppressants, guide transplant decisions, and inform the genetic risks of their family members. Yet, genetic testing for kidney disease is under-utilized in Singapore. We aimed to implement a nephrologist-led genetic service and evaluate the acceptance, adoption, utility and cost-effectiveness of genetic testing for monogenic glomerular disease in Singapore. Methods We will perform a prospective, multi-center, Type II hybrid effectiveness-implementation study with a post design to evaluate both implementation and clinical outcomes of nephrologist-led genetic testing for suspected genetic glomerular kidney diseases. The multi-disciplinary implementation team will train "genetic nephrologists" to provide pre- and post-test counselling, order targeted exome panel sequencing for suspected glomerular kidney diseases (persistent microscopic haematuria and/or albuminuria or proteinuria in the absence of known causes; steroid-resistant primary nephrotic syndrome; apparent familial IgA nephropathy; or chronic kidney disease with no apparent cause) and interpret genetic test results; create workflows for patient referral, evaluation and management, and discuss genetic results at regular genomic board meetings. The outcomes are acceptance, appropriateness and adoption among patients and nephrologists, utility (proportion of patients who received genetic testing and have a confirmed diagnosis of genetic glomerular disease) and cost-effectiveness. Conclusion This study will create and evaluate a nephrologist-led genetic service, develop an efficient variant curation process and inform future recommendations on the optimal referral and genetic testing strategy for monogenic glomerular disease in Singapore. This will facilitate the future mainstreaming of genetic testing that will enable precision medicine in kidney care.

Numerical Simulation of Anchor Pullout and Shear Tests Using a Regularized Damage Model

The prediction of the mechanical behavior of anchorage plates in reinforced concrete is crucial for ensuring equipment reliability, particularly in sensitive installations. This paper employs finite element analysis to forecast the experimental outcomes of anchor pullout and shear tests. In this article, a regularized damage model is proposed to simulate the effects of loads transmitted to the concrete by the anchor rod. Specifically, a modified Mazars model is introduced, incorporating an “energetic” regularization in both tension and compression. The model is validated for a single anchor rod under tension and subsequently for a complete anchorage system subjected to both tension and shear forces. Various failure modes, such as concrete cone cracking or steel rupture, are accurately represented, alongside the overall anchorage strength. This approach, thus, faithfully reproduces the mechanical behavior of anchorage plates, ensuring equipment robustness under diverse loading conditions.

Task design and rater effects in task‐based language assessment

AbstractTask‐based language assessment represents a major component of task‐based language teaching syllabi. Current perspectives emphasise the importance of tasks in the assessment process, suggesting that adherence to influential models of language production during task design yields predictable test outcomes. The current study contends that the significance of the rater has been overlooked, resulting in adverse consequences when employing current task‐based frameworks. The article reviews literature on the rating process, with a focus on interactions between rater characteristics, rating scales, and rater effects. Drawing on the findings of the review, the author proposes a revised model of task‐based language assessment that curbs the impact of task design on test scores. The revised model underscores the need to regard raters as active agents in the assessment process to enhance validity and fairness and makes recommendations about minimizing rater effects.

A qualitative description of HIV testing and healthcare experiences among trans women in Ghanaian urban slums BSGH-012.

Achieving the UNAIDS 90-90-90 targets hinges on identifying and engaging individuals with HIV in care, requiring 90% of those infected to be diagnosed, initiated on ART, and achieving viral suppression. Despite this imperative, HIV testing services as well as research in Ghana often overlook the unique experiences of transgender women in urban slums, impacting their engagement with care. Using the gender affirmative model lens, this study reports the HIV testing experiences of trans women in Ghanaian slums, highlighting how the healthcare environment, counseling, and healthcare provider attitudes shape these experiences. The study used a qualitative descriptive interview design with 20 trans women aged 18 to 31 from urban slums in Greater Accra Metropolitan Area, Ghana. Participants were recruited through purposive and snowball sampling. Data were collected via face-to-face interviews, transcribed, and analyzed using NVivo, with results presented in categories and subcategories. Two main categories emerged from our data analysis: 1) Positive Experiences with HIV Testing, and 2) Negative Experiences with HIV Testing. Positive experiences with HIV testing among trans women in Ghanaian slums included a welcoming environment at healthcare facilities, supportive counseling, and relatability with HIV-positive nurses. Negative experiences were characterized by fear and anxiety during testing, often intensified by healthcare worker attitudes, including unwelcoming behaviors and judgmental body language, especially in facilities that are not key population friendly. These categories provided a framework for understanding the varied experiences of trans women in Ghanaian slums regarding HIV testing. The study highlights the urgent need for Ghanaian slum healthcare facilities to address discrimination against trans women by creating inclusive, supportive environments. It stresses the importance of using a gender-affirmative approach to improve HIV testing and health outcomes for trans women. Policymakers and healthcare providers must focus on training, inclusive care, and cultural competence to reduce health disparities for this population.

The Implementation of Enterprise Resource Planning During the Product Design Process Through the Process of Design Thinking

The implementation of Enterprise Resource Planning (ERP) systems in the product design phase plays a crucial role in modern industries. The product design phase with the design thinking approach produces an innovative product that meets user requirements. The product design process, which begins with capturing user requirements and culminating in a thorough specification of a finished product, requires extensive data and expertise. Iterative product design processes contribute to the complexity of the data that must be managed within an organization. This study involved the implementation of an Enterprise Resource Planning (ERP) software named Odoo within the product design process using a design thinking methodology. By examining the student practicum activities in automotive design, starting from the user survey phase and going all the way to the component design details, a comprehensive ERP system was developed. This system is capable of seamlessly integrating all the data throughout the entire process. Based on the outcomes of testing and assessment, it can be concluded that the modules in Odoo software can be effectively integrated into the product design process. Effective processes in integrating ERP into product design phases can improve production quality and efficiency as well as facilitate greater flexibility and innovation. Implementing ERP throughout the product design phase results in a seamless flow of information, enhanced inventory control, and overall productivity enhancement. This ultimately leads to operational efficiency, competitive advantage, and high user satisfaction in the industry.

Study on icing characteristics of bundled conductor of transmission line based on shadowing effect analysis

Icing on transmission lines significantly threatens the safety and stability of power system. Particularly for bundled conductors, the shadowing effect of the upwind conductor on the downwind one affects airflow and droplet distribution, leading to unique icing characteristics. This paper employs numerical simulations and icing tests to investigate the icing shadowing effect of bundled conductors. Firstly, the distributions of airflow and droplets around the bundled conductor are solved by the Eulerian-Eulerian two-phase flow model. Then, by solving mass and thermodynamic balance equations, the icing mass and shape accreted on the bundled conductors under various icing conditions are obtained. Further, two novel parameters, the shadowing coefficient and the offset angle, are introduced to quantify the shadowing effect's impact on ice mass and shape. The findings indicate that the ice mass ratio on the downwind conductor to the upwind conductor is influenced by wind speed, wind angle, bundle spacing, conductor diameter, and droplet parameters. In most cases, the ratio is less than 1; however, under certain wind angles, this ratio exceeds 1. The shadowing effect also impacts the ice shape on the downwind conductor, inducing an additional offset in the ice shape. The magnitude of this offset angle is also correlated with environmental parameters. Finally, the accuracy of our numerical simulations is validated by the outcomes of natural icing tests.

Isokinetic Dynamometry for External and Internal Rotation Shoulder Strength in Youth Athletes: A Scoping Review.

Accurately measuring shoulder strength in overhead athletes is critical, as sufficient strength is essential for safe and sustained performance during repetitive athletic movements. Isokinetic dynamometry (ID) offers dynamic strength assessments that surpass the capabilities of static methods, such as manual muscle testing and handheld dynamometry. The dynamic assessment provided by ID may enhance upper extremity evaluation, aiding in the prediction of injury risk and the determination of return-to-sport criteria for overhead athletes. The purpose of this review was to examine the existing literature concerning the application of isokinetic shoulder strength testing in rehabilitation and clinical decision-making processes among youth athletes who perform repetitive overhead activities. Scoping review. A comprehensive literature search was conducted using PubMed and EBSCO Host databases, covering publications from 2000-2024. Search terms included "isokinetic dynamometry," "shoulder," and "youth athlete." Inclusion criteria focused on youth athletes (<18 years) engaged in overhead sports, excluding those with neurological conditions or those designated as college or professional athletes. The PRISMA-ScR guidelines were followed. A total of 23 articles met the inclusion criteria. Volleyball and swimming were the most studied sports, with the most common testing position being the seated 90/90 position. Variations in testing speeds and outcome measures, such as peak torque and external rotation (ER) ratios, were identified. Isokinetic dynamometry is a valuable tool for assessing shoulder strength in youth overhead athletes. It provides critical insights into muscle strength dynamics, aiding in injury prevention and rehabilitation. Further research is needed to optimize strength assessment protocols and enhance clinical decision-making for safe return-to-sport practices.

Study on flexural resilience of composite foam sandwich structures under hygrothermal environment

Under hygrothermal environments, the structural stability and strength of all-fiber composite aircraft are significantly affected during long-term flight use. The wing skin, as a critical structural component, plays a vital role in bearing and transmitting aerodynamic loads. Therefore, it is crucial to investigate the structural compressive stability and strength of the wing skin throughout the aircraft's entire life cycle under these conditions. This study employs a real wing carbon fiber foam sandwich structure to investigate the compressive stability and strength of the wing skin structure of a new energy aircraft under actual flight conditions, specifically during the entire process of the room temperature dry state (RTD) and elevated temperature wet state (ETW). Initially, three-point bending tests were conducted on carbon fiber reinforced polymer (CFRP) laminates, foam cores, and CFRP reinforced foam sandwich structures. The CFRP laminates fully rebounded after bending damage in both the RTD and ETW environments. While CFRP reinforced foam sandwich structures also rebounded fully in the RTD environment, their rebound performance diminished in hygrothermal conditions due to the thermoplastic mobility of the foam cores, resulting in only weak rebound capabilities. In hygrothermal environments, the thermoplastic mobility of the foam core leads to diminished resilience after bending damage, resulting in only weak rebound capabilities. Subsequently, compressive instability tests were conducted on the wing skin foam sandwich structure. The results indicated that the basic test study effectively predicted the structural test outcomes. Structural components in the RTD environment exhibited overall flexural instability under compressive load, with damage morphology resembling a circular curve; the damaged specimens fully rebounded after unloading. Conversely, specimens in the ETW environment displayed localized instability, characterized by a wrinkled damage profile, resulting in only weak rebound capabilities after unloading.

Beyond the blur: Scopolamine's utility and limits in modeling cognitive disorders across sexes - narrative review.

Scopolamine, widely regarded as the gold standard in preclinical studies of memory impairments, acts as a non-selective antagonist of central and peripheral muscarinic receptors. While its application in modeling dementia primarily involves antagonism at the M1 receptor, its non-selective peripheral actions may introduce adverse effects that influence behavioral test outcomes. This review analyzes preclinical findings to consolidate knowledge on scopolamine's use and elucidate potential mechanisms responsible for its amnestic effects. We focused on recognition, spatial and emotional memory processes, alongside executive functions such as attention, cognitive flexibility, and working memory. The cognitive effects of scopolamine are highly dose-dependent, influenced by factors such as species, age, and sex of subjects. Notably, scopolamine rapidly induces observable memory impairments across species, from fish to rodents and primates, often with deficits that can persist for days. However, the compound's broad action on muscarinic receptors and its peripheral side effects, including pupil dilation and reduced salivation, complicates result interpretation, particularly in tasks requiring visual discrimination or food intake. The review also highlights scopolamine's translational value in modeling dementia and Alzheimer's disease, emphasizing the importance of considering individual factors and task-specific designs. Despite its widespread use, scopolamine's limited specificity for cholinergic dysfunction and inability to fully mimic the complex pathophysiology of cognitive disorders like Alzheimer's and Parkinson's disease point to the need for complementary models. This review aims to guide researchers in using scopolamine for modeling cognitive impairments, ensuring attention to factors impacting experimental outcomes.

Shear performance of 25 m full-scale prestressed UHPC-NC composite I-beam without stirrups

The burgeoning preference for prestressed Ultra-High Performance Concrete (UHPC) I-girders without stirrups, stemming from the remarkable tensile strength of UHPC, indicating a promising trajectory for future construction endeavors. This research delved into real-world engineering scenarios, focusing on shear tests conducted on both 9.0m and 6.5m segments cut off a 25.0m full-scale prestressed UHPC-NC composite I-beam without stirrups, which had already undergone flexural failure. Employing Finite Element Models (FEM), the study scrutinized and forecasted test outcomes. In asymmetric loading shear test, the end with a lower shear span ratio and higher shear capacity fails earlier. Subsequently, a validated FEM, reflective of the tested beam, was established. Leveraging this validated model, a comprehensive analysis ensued, probing into parameters influencing the shear performance of the full-scale prestressed UHPC-NC composite I-beam without stirrups. Parameters under study encompassed the prestressed tension level, web width, and shear span ratio. Findings revealed minimal impact of prestressed tension level on the shear performance of the tested beam, with augmented web width substantially enhancing stiffness and shear capacity. Conversely, an increase in shear span ratio correlated with a decline in shear performance of the tested beam. Finally, it juxtaposed various predictive equations for the shear capacity of the beams without stirrups from disparate global locales, advocating for the utilization of equations outlined in the French equation to predict the shear capacity of the tested beams in this study, aiming for minimized margin of error and conservative estimation.

Tracking Shaft Integrity of Jet Grouting Piles Injected in Soft Soil Layers Based on Sonic Integrity Test Method: A Case Study from Erdemli, Mersin Region, South Turkey

Many studies have focused on using the non-destructive testing (NDT) method to determine defects in piles. This paper presents an analytical approach that compares the obtained profiles with typical profiles to confirm the integrity of jet grouting column piles using the cast-in-situ Sonic Integrity Testing (SIT) method. In this context, grouting piles are being constructed within the scope of the under-foundation in Erdemli/Mersin Province, Turkey. SIT testing was performed on jet grouting piles by performing integrity tests on piles manufactured, which varied in length according to the field geology and the thickness of the soil layer. These pile tests are performed to determine changes that may occur in the pile's cross-section for various reasons. In the present study (in 2024) SIT was carried out on a total of 148 jet grout piles. In the SIT performed on the piles, at least six records were taken for each pile, the records were examined, and the evaluations and results were given graphically. The cross-sectional alterations and fractures that can be found in the pile cross-section as well as the subsurface soil condition are the outcomes of the integrity tests, and they have an immediate impact on carrying capacity. Based on the acquired data and comparisons with reference profiles, the 148 piles that were produced and examined at the site exhibit no discontinuities or flaws and are structurally intact. By utilizing this method, the necessity for costly on-site soil replacement or foundation handling will be avoided or prevented.

Study on dynamic mechanical properties and damage characteristics of wollastonite fiber reinforced oil well cement paste

In cement engineering, the cement sheath is not only influenced by elevated temperatures, increased pressure, and the static load confining pressure within the formation but also encounters external impact loads. These loads can rupture the cement paste, compromising the cement sheath’s interlayer sealing capability. Consequently, this can give rise to an annular flow of oil, gas, and water. Hence, this study introduces wollastonite fiber (WF) into the cement slurry to modify the cement paste. The investigation explores the mechanical properties, energy evolution, and damage characteristics of the cement paste with WF under dynamic impact loads. This is achieved by simulating the dynamic impact loads experienced downhole using the separated Hopkinson pressure bar (SHPB) technique. A straightforward SHPB model is constructed using ABAQUS finite element simulation software, and its accuracy is confirmed through experimental validation. The impact test outcomes revealed a notable enhancement in the dynamic load peak strength of the cement paste cured for 14 days. Specifically, there was an increase of 136.75%, 202.10%, and 320.55% compared to the control group at impact speeds of 6 m/s, 8 m/s, and 10 m/s, respectively. The absorption energy increased remarkably, showing 356.03%, 388.61%, and 142.14%, respectively. The simulation findings confirm that the devised simple SHPB model effectively replicates electrical signals aligned with the observed experimental results. The dispersed fibers create a three-dimensional network within the cement paste. This network enhances the impact resistance of the cement paste by leveraging the mechanisms of crack deflection, fiber fracture, and energy dissipation through fiber pull-out.

Accounting for learning environments in academic screening

Within multi-tiered systems of support (MTSS) practice and research, students' need for academic intervention is often determined by comparison of students' screening scores to cut scores. We examined the degree to which the relationship between students' fall screening data (i.e., Measures of Academic Progress) and their outcome on a spring summative state test related to the quality of the classroom learning environment and how core instructional strategies influenced this relationship. Fall screening data and spring state test outcomes in English/language arts (ELA) and math were analyzed from a sample of 72 teachers and 1554 third-grade students. Multilevel logistic regression revealed that the association between students' ELA or math skills at the beginning of a school year and state test at the end of the year were not identical across classrooms (odds ratios range = 0.81–0.92). A significant interaction was observed between students' fall ELA screening scores and teachers' instructional strategy use in predicting state test outcomes (p = .03). Teacher strategy use was found to be a significant contributor to false positives in screening decisions based on optimal cut scores for ELA (p = .003), but not math.
