Characterizing the Effects of Concussion and Head Impact Exposure: Design, Methods, and Participant Traits of the CARE 2.0 Study.

This article describes the design, methods, and participant characteristics of the second phase of the Concussion Assessment, Research, and Education (CARE) Consortium study ("CARE 2.0") of the effects of concussion and repetitive head impact exposure on neuropsychiatric health. The authors conducted a prospective multisite observational study of male and female collegiate athletes and military service academy cadets and midshipmen participating in the CARE study. Participants were assessed at three time points: undergraduate baseline (UB), before departure from university or service academy (exit), and up to 6 years following graduation (postgrad) via an online battery of brain health assessments. Participant characteristics were compared across the three time points and four levels of head impact exposure. A total of 4,643 participants completed the exit assessment, and 3,981 completed the postgrad assessment. Relative to the UB assessment cohort, the exit and postgrad assessment cohorts differed with respect to the percentage of women, baseline Wechsler Test of Adult Reading scores, National Collegiate Athletic Association division category, sport contact level, and number of previous concussions. The median standardized difference across balancing variables, assessment time points, and degree of head impact exposure was 0.12 (with 90% of effect sizes ≤0.29). Although there were some statistically significant differences between participants across assessments, the effect sizes were modest, and overall the data suggest that the exit and postgrad cohorts reflect the characteristics of the baseline cohort. The CARE study design and its large, richly characterized sample provide an opportunity to answer important questions about cumulative and persistent effects of concussion and repetitive head impact exposure on neuropsychiatric health.

Application of a validated prognostic plasma protein biomarker test for renal decline in type 2 diabetes to type 1 diabetes: the Fremantle Diabetes Study Phase II

BackgroundThere are scant data relating to prognostic biomarkers for chronic kidney disease (CKD) complicating type 1 diabetes. The aim of this study was to assess the performance of the plasma protein biomarker-based PromarkerD test developed and validated for predicting renal decline in type 2 diabetes in the context of type 1 diabetes.MethodsThe baseline PromarkerD test score was determined in 91 community-based individuals (mean age 46.2 years, 56.5% males) with confirmed type 1 diabetes recruited to the longitudinal observational Fremantle Diabetes Study Phase II. The performance of the PromarkerD test in predicting the risk of incident CKD (estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73m2 in people without CKD at baseline) or an eGFR decline of ≥ 30% over the next four years was determined. The score can range from 0 to 100%, and is categorized as representing low (< 10%), moderate (10% to < 20%) or high (≥ 20%) risk.ResultsThe area under the receiver operating characteristic curve was 0.93 (95% confidence interval 0.87–0.99) for the composite renal endpoint, indicating strong predictive accuracy. The positive and negative predictive values at moderate (10% to < 20%) and high (≥ 20%) risk PromarkerD cut-offs were 46.7–50.0% and ≥ 92.0%, respectively.ConclusionsThese preliminary data suggest that PromarkerD is at least as good a prognostic test for renal decline in type 1 as type 2 diabetes.

Preliminary assessment of a robotic system for overground gait in children with cerebral palsy

PurposeCerebral palsy is one of the leading causes of chronic disability in children. The current pilot study investigated (1) whether an exoskeleton system enables physiological gait patterns and (2) whether the system is user-friendly enough to envision its use in a clinical setting.Design/methodology/approachParticipants included a convenience sample of six children with cerebral palsy. Following informed consent, study volunteers underwent baseline assessments, participated in eight sessions during which they used the exoskeleton system with the objective of achieving proficiency in use of the system, and underwent an end-of-study assessment of walking. Satisfaction and usability questionnaires were given to the family/caregiver.FindingsAll participants achieved a more regular gait pattern and improved their 6-Minute Walk Test scores. Overall satisfaction and usability were rated as good.Practical implicationsThe exoskeleton system enabled physiological gait patterns, and the system was user-friendly enough to envision its use in a clinical setting.Originality/valueThere is potential for guiding treatment plans for individuals with cerebral palsy.

Mode of delivery and behavioral and neuropsychological outcomes in children at 10 years of age.

Previous studies have reported that mode of delivery, particularly cesarean delivery (CD), is associated with neurodevelopmental outcomes in children. This study evaluates behavioral and neuropsychological test scores in children based on mode of delivery. Children enrolled in the Raine Study from Western Australia, born between 1989 and 1992 by instrumental vaginal delivery (IVD), elective CD, and non-elective CD, were compared to those with spontaneous vaginal delivery (SVD). The primary outcome was the Child Behavior Checklist (CBCL) administered at age 10. Secondary outcomes included evaluations of language, motor function, cognition, and autistic traits. Multivariable linear regression was used to evaluate score differences by mode of delivery adjusted for sociodemographic and clinical characteristics, and Poisson regression was used to evaluate for increased risk of clinical deficit. Of 2,855 children, 1770 (62.0 %) were delivered via SVD, 480 (16.8 %) via IVD, 346 (12.1 %) via elective CD, and 259 (9.1 %) via non-elective CD. Non-elective CD was associated with higher (worse) CBCL Internalizing (+2.09; 95 % CI 0.49, 3.96; p=0.01) scores, and elective CD was associated with lower (worse) McCarron Assessment of Neuromuscular Development (MAND) (-3.48; 95 % CI-5.61,-1.35; p=0.001) scores. Differences were not seen in other outcomes, and increased risk of clinical deficit was not observed with either the CBCL Internalizing or MAND scores. Differences in behavior and motor function were observed in children delivered by CD, but given that score differences were not associated with increased incidence of clinical deficit, clinical significance may be limited.

Serum Derivatives–Reactive Oxygen Metabolite Levels as a Marker of Clinical Conditions in Patients with Bronchial Asthma, COPD, or Asthma–COPD Overlap: A Prospective Study

Background: Oxidative stress plays an important role in the pathophysiology of bronchial asthma (BA), chronic obstructive pulmonary disease (COPD), and asthma–COPD overlap (ACO), but its relevance has not been fully elucidated. The aim of this study was to measure the levels of oxidative stress and investigate its clinical significance in patients with BA, COPD, or ACO. Methods: We recruited 214 patients between June 2020 and May 2023 (109 patients with BA, 63 with COPD, and 42 with ACO). To assess clinical conditions, we evaluated patient characteristics, results of respiratory function tests and blood tests, and administered several questionnaires. We evaluated oxidative stress using the test for derivatives–reactive oxygen metabolites (d–ROMs) in serum. Results: The d–ROMs levels were significantly higher in patients with COPD or ACO than in patients with BA. There was no difference in serum d–ROMs levels between the COPD and ACO groups. In BA, d–ROMs levels were positively correlated with interleukin (IL)-6, IL-8, serum amyloid A (SAA), and C-reactive protein (CRP) levels; white blood cell (WBC) and neutrophil counts; and St. George’s Respiratory Questionnaire (SGRQ) scores, and they were negatively correlated with forced expiratory volume in 1 s (%FEV1) and asthma control test (ACT) score. In COPD, d–ROMs levels were positively correlated with IL-6, SAA, and CRP levels; WBC, neutrophil, and eosinophil counts; and COPD assessment test (CAT) and SGRQ scores, and they were negatively correlated with forced vital capacity (%FVC), %FEV1, and %FEV1/FVC scores. In ACO, d–ROMs levels were positively correlated with IL-6, SAA, tumor necrosis factor alpha (TNF-α), and CRP levels; and CAT and SGRQ scores, and they were negatively correlated with %FVC and %FEV1 scores. Conclusions: Serum d–ROMs levels may serve as a marker reflecting clinical conditions such as systemic inflammation, symptom severity, and airflow limitation in patients with BA, COPD, and ACO.

Physical Activity and Cognitive Function Among Older Adults, United States

ABSTRACT Introduction Physical activity (PA) is a modifiable risk factor associated with cognitive health. However, the existing literature regarding the relationship between PA and cognitive functions among individuals ≥ 60 years remains inconclusive. Method We used data from the 2011–2014 National Health and Nutrition Examination Survey for this study. The Global Physical Activity Questionnaire (GPAQ) was used to assess PA. Cognitive function was assessed using the Animal Fluency Test Score. Multinomial logistic regression was used to examine the association adjusting for potential confounders. Results A total of 2947 participants were included in the analyses. Among the participants, 32% were physically active, males (53%), and non-Hispanic White individuals (80%). Physically active participants had decreased odds of Alzheimer’s disease (AOR 0.63, 95% CI: 0.45–0.89). In the gender- and race-specific strata, PA was associated with reduced odds of Alzheimer’s among females (AOR 0.54, CI: 0.34–0.86) and non-Hispanic White individuals (AOR 0.54, CI: 0.30–0.97). Conclusion Age, gender, and race modify the association between PA and cognitive function. Further research is needed to study the different forms of PA and their association with cognitive function.

Oral State and Salivary Cortisol in Multiple Sclerosis Patients

Background: MS patients experience gradual and progressive functional limitation, bulbar symptoms, cognitive dysfunction, and psychiatric disorders that can impinge on oral status. This study aimed to investigate the oral state, oral hygiene habits, and salivary cortisol levels in patients with relapsing-remitting multiple sclerosis (RRMS) compared to healthy controls. It also evaluated systemic parameters: disease duration, type of Disease Modifying Therapy (DMT), disability score, professional activity, and smoking in the study group. Methods: This study included 101 patients (71 women and 30 men, aged 16–71 years) and 51 healthy volunteers (36 women and 15 men, aged 28–82 years). The oral examination assessed the number of teeth, type and number of dental fillings and prosthetic restoration, oral hygiene state, and salivary cortisol. Results: It was found that MS patients had significantly more professional activity, swallowing problems, pronunciation issues, dry mouth, and taste disturbances than the control group. They brushed their teeth twice daily significantly less often. The API was higher, while the SBI was lower in MS patients. Disease duration positively correlated with age and number of missing teeth. The Expanded Disability Status Scale positively correlated with age, disease duration, number of missing teeth, number of composite fillings, and right and left-hand Nine Hole Peg test scores, and negatively correlated with the Sulcus Bleeding Index. Salivary cortisol levels did not differ between groups and correlated only with the disability scale. Conclusions: MS patients require ongoing dental care and preventive measures to manage both general and oral health symptoms effectively.

Neurodevelopmental outcomes among children with congenital gastrointestinal anomalies using Korean National Health Insurance claims data.

This study investigated neurodevelopment and risk factors in children surgically treated for congenital gastrointestinal anomalies (CGIA), excluding those with known high-risk factors such as low birth weight or chromosomal anomalies. Data of children born between 2008 and 2015 who underwent surgical treatment for CGIA were retrieved from the Korean National Health Insurance Database. CGIA included esophageal atresia, duodenal atresia, jejunoileal atresia, anorectal malformations, and congenital megacolon. Neurodevelopmental impairment (NDI) was defined as Korean Ages and Stages Questionnaire scores below the determined cut-off or Korean Developmental Screening Test scores < 2 standard deviations at 3 years of age. Children with CGIA had a significantly higher risk of NDI than controls (6.2% vs. 2.7%, p < 0.001). Growth failure was correlated with NDI. Longer durations of oxygen support (adjusted odds ratio [aOR], 1.037; 95% confidence interval [CI], 1.013-1.063), mechanical ventilation (aOR, 1.053; 95% CI, 1.018-1.089), and number of surgeries (aOR, 1.137; 95% CI, 1.016-1.273) were significantly associated with NDI. These findings emphasize that cautious yet proactive neurodevelopmental monitoring is crucial in affected children, ensuring timely intervention and that excessive concern among families is unnecessary.

Comparison of Web-Based and On-Site Lung Simulators for Education in Mechanical Ventilation.

Training in mechanical ventilation is a key goal in critical care fellowship education. Web-based simulators offer a cost-effective and readily available alternative to traditional on-site simulators. However, it is unclear how effective they are as teaching tools. In this study, we evaluated the test scores of fellows who underwent mechanical ventilation training by using a web-based simulator compared with fellows who used an on-site simulator during a mechanical ventilation course. This was a nonrandomized controlled trial conducted as part of a mechanical ventilation course that involved 70 first-year critical care fellows. The course was identical except for the simulation technology used. One group of instructors used a traditional on-site simulator, the ASL 5000 Lung Solution (n = 39). The second group was instructed in using a web-based simulator, VentSim (n = 31). Each fellow completed a pre-course test and a post-course test by using a validated, case-based ventilator waveform examination that consisted of 5 questions with a total possible score of 100. The primary outcome was a comparison of the mean scores on the posttest between the 2 groups. The study was designed as a non-inferiority trial with a predetermined margin of 10 points. There was no significant difference in the mean ± SD pretest scores between the web-based and the on-site groups (21.1 ± 12.6 and 26.9 ± 13.6 respectively; P = .11). The mean ± SD posttest scores were 45.6 ± 25.0 for the web-based simulator and 43.4 ± 16.5 for on-site simulator (mean difference 2.2; one-sided 95% CI -7.0 to ∞; P non-inferiority = .02 [non-inferiority confirmed]). Changes in mean ± SD scores (posttest - pretest) were 25.9 ± 20.9 for the web-based simulator and 16.5 ± 15.9 for the on-site simulator (mean difference 9.4, one-sided 95% CI 0.9 to ∞; P non-inferiority < .001 [non-inferiority confirmed]). In the education of first-year critical care fellows on mechanical ventilation waveform analysis, a web-based mechanical ventilation simulator was non-inferior to a traditional on-site mechanical ventilation simulator.

The effect of augmented reality storybooks on the story comprehension and retelling of preschool children

This study aimed to compare the retelling and story comprehension performance of two groups of preschool children—an experimental and a control group—who experienced printed and augmented reality storybooks. The participant group consisted of 90 participants, with 45 in the experimental group (22 girls, 23 boys) and 45 in the control group (21 girls, 24 boys). The average age of the children was 54.2 months. In the study, the researcher evaluated children’s story-retelling performance using the rubric and used a Story Comprehension Test to measure their story comprehension performance. The researchers utilized the ROAR application to incorporate augmented reality content into the books. In the pre-test phase, the teachers read the designated texts to the children in the experimental and control groups. After the eight-week break, the control group experienced the same texts with printed books, while the experimental group experienced them with augmented reality support. Each child participated individually in the reading process with the teacher. In the study, teachers asked the children to retell the story and asked the questions from the Story Comprehension Test at the end of each book reading section for pre-test and post-test measurements. The pre-test results revealed no significant difference in the two groups’ story-retelling and Story Comprehension Test scores. The post-test results indicated a significant difference in the story-retelling performance and Story Comprehension Test scores between the experimental and control groups, favoring the experimental group. Based on these findings, the augmented reality content can potentially enhance children’s retelling and story comprehension performances.

Educational Spillover Effects of New English Learners in a New Destination State

The number of English learners (ELs) enrolled in public schools has grown substantially in the United States over the past two decades. The growth is especially large in states in the South and Midwest that have not been traditional destinations for recent immigrants. In this study, we examine the effects of new ELs on students in receiving schools in Delaware, which is one of the so-called new destination states. We find significant positive spillover effects in the short term of new ELs on the test scores of the other students in the receiving schools. The positive effects are mainly concentrated among current and former ELs.

UroARC: A novel surgical risk calculator for older adults undergoing pelvic organ prolapse and stress urinary incontinence surgery.

Surgeries for pelvic organ prolapse (POP) and stress urinary incontinence (SUI) are commonly performed in older adults, many of whom are also frail. A surgical risk calculator for older adults undergoing POP/SUI surgeries that incorporates frailty, a factor known to increase the risk of surgical complications, would be helpful for preoperative counseling but currently does not exist. Medicare Carrier, Outpatient, and MedPAR files were examined for beneficiaries undergoing POP and SUI surgery between 2014 and 2016. A total of 15 POP/SUI categories were examined. The Claims-Based Frailty Index (CFI), a validated measure of frailty in Medicare data, and Charlson Comorbidity Index were deconstructed into their individual variables, and individual variables were entered into stepwise logistic regression models to determine which variables were most highly predictive of 30-day complications and 1-year mortality. To verify the prognostic accuracy for each model for surgical complications of interest, calibration curves and tests of model fit, including C-statistic, Brier scores, and Spiegelhalter p values, were determined. In total, 108 479 beneficiaries were included. Among these, 4.7% had CFI scores consistent with mild to severe frailty (CFI≥0.25). A total of 13 prognostic variable categories were found to be most highly predictive of postoperative complications. Calibration curves for each outcome of interest showed models were well-fit. Most models demonstrated high c-statistic values (≥0.7) and high Spiegelhalter p values (≥0.9), indicating good model calibration and excellent discrimination, and low Brier scores (<0.02), indicating high model accuracy. Urologic surgery for older Adults Risk Calculator serves as a novel surgical risk calculator that is readily accessible to both patients and clinicians that specifically factors in components of frailty. Furthermore, this calculator accounts for the heterogeneity of an aging population and can assist in individualized surgical decision-making for these common procedures.

Enhancing medical education for undergraduates: integrating virtual reality and case-based learning for shoulder joint

BackgroundThe integration of Virtual Reality (VR) with Case-Based Learning (CBL) has the potential to revolutionise undergraduate medical education, particularly in complex subjects such as the anatomy and rehabilitation of the shoulder joint. This study aimed to explore the effectiveness of this innovative approach in enhancing learning outcomes and knowledge retention.MethodsThis study employed a parallel-group, assessor-blinded randomised controlled trial (RCT) design. A comprehensive five-week educational programme was developed, combining traditional lecture-based learning with VR-enhanced CBL. The study involved 82 undergraduate students from China Medical University, who were divided into groups receiving different combinations of VR and CBL. Student performance was evaluated through tests and questionnaires.ResultsIn the anatomy-related courses, the integration of VR technology with CBL yielded significantly higher results (87.71 ± 5.60) compared to traditional methods (82.59 ± 6.64), with a statistically significant difference (P < 0.05). This provides compelling evidence of VR's potential to enhance student engagement and knowledge retention. In the context of physiotherapy-related courses, however, while the test scores of the VR-combined CBL group (81.85 ± 5.99) were marginally higher than those of the traditional CBL group (79.02 ± 7.57), this difference was not statistically significant (P > 0.05).ConclusionThe present study provides preliminary evidence for the benefits of incorporating VR into medical education, particularly in anatomy. While the results are promising, further research is needed to explore the optimal integration of VR and CBL in rehabilitation studies and to assess their long-term impact on student learning and clinical performance.Trial registrationThe study was registered with Chinese Clinical Trials Registry (Registration Number: ChiCTR2400089295) on 05/09/2024.

Age-Related Listening Performance Changes Across Adulthood.

This study compares auditory processing performance across different decades of adulthood, including young adults and middle-aged individuals with normal hearing and no spontaneous auditory complaints. We assessed 80 participants with normal hearing, at least 10 years of education, and normal global cognition. The participants completed various auditory tests, including speech-in-noise, dichotic digits, duration, pitch pattern sequence, gap in noise, and masking level difference. In addition, we conducted working memory assessments and administered a questionnaire on self-perceived hearing difficulties. Our findings revealed significant differences in auditory test performance across different age groups, except for the masking level difference. The youngest group outperformed all other age groups in the speech-in-noise test, while differences in dichotic listening and temporal resolution emerged from the age of 40 and in temporal ordering from the age of 50. Moreover, higher education levels and better working memory test scores were associated with better auditory performance as individuals aged. However, the influence of these factors varied across different auditory tests. It is interesting that we observed increased self-reported hearing difficulties with age, even in participants without spontaneous auditory complaints. Our study highlights significant variations in auditory test performance, with noticeable changes occurring from age 30 and becoming more pronounced from age 40 onward. As individuals grow older, they tend to perceive more hearing difficulties. Furthermore, the impact of age on auditory processing performance is influenced by factors such as education and working memory.

This research explores the effectiveness of the Project Based Learning (PBL) method in enhancing student learning outcomes in Catholic Religious Education and Character Education in Phase D for ninth-grade students at UPTD Negeri 3 Lolofitu Moi. Using a quantitative approach, this study involved 10 students from the school and employed an experimental design to analyze the impact of PBL on understanding the material related to Rights and Obligations as Members of the Church and Society. Data were collected through observations of teacher activities, student activities based on observation sheets, group discussions, the learning process, and the completion of student worksheets. The results showed that teacher activity in implementing PBL improved from 68.7% (good) to 98.8% (excellent). The findings indicate a significant increase in quiz test scores, from 50% (good) student mastery to 90% (excellent), suggesting progress in material comprehension. Further observations revealed that student engagement in the learning process and group discussions increased from 68.7% (good) to 98.4% (excellent), which not only enriched their learning experience but also developed collaborative skills and critical thinking. These findings confirm that the PBL method, with a focus on collaborative learning, can be an effective strategy for enhancing learning outcomes and student motivation in religious education. This study recommends the broader implementation of the PBL method in religious education curricula, as well as further research to explore other variables that may influence student learning outcomes.

High-Precision Heterogeneous Satellite Image Manipulation Localization: Feature Point Rules and Semantic Similarity Measurement

Misusing image tampering software makes it easier to manipulate satellite images, leading to a crisis of trust and security concerns in society. This study compares the inconsistencies between heterogeneous images to locate tampered areas and proposes a high-precision heterogeneous satellite image manipulation localization (HSIML) framework to distinguish tampered from real landcover changes, such as artificial constructions, and pseudo-changes, such as seasonal variations. The model operates at the patch level and comprises three modules: The heterogeneous image preprocessing module aligns heterogeneous images and filters noisy data. The feature point constraint module mitigates the effects of lighting and seasonal variations in the images by performing feature point matching, applying filtering rules to conduct an initial screening to identify candidate tampered patches. The semantic similarity measurement module designs a classification network to assess RS image feature saliency. It determines image consistency based on the similarity of semantic features and implements IML using predefined classification rules. Additionally, a dataset for IML is constructed based on satellite images. Extensive experiments compared with existing SOTA models demonstrate that our method achieved the highest F1 score in both localization accuracy and robustness tests and demonstrates the capability for handling large-scale areas.
