Endovascular Inferior Vena Cava Filters Placed in Duplicated Inferior Vena Cava Syndrome.

Duplicated inferior vena cava (D-IVC) is a relatively rare anatomical anomaly. Clinically, these anomalies are incidentally found on computed tomography (CT) or magnetic resonance imaging (MRI). Lack of pre-operative identification of this congenital malformation can lead to incomplete protection against thromboembolism or hemorrhage. We present a case of a 71-year-old male with a duplicated inferior vena cava who underwent insertion of bilateral inferior vena cava filters for deep vein thrombosis (DVT) management.

MIDRC-MetricTree: a decision tree-based tool for recommending performance metrics in artificial intelligence-assisted medical image analysis.

Purpose: The Medical Imaging and Data Resource Center (MIDRC) was created to facilitate medical imaging machine learning (ML) research for tasks including early detection, diagnosis, prognosis, and assessment of treatment response related to the coronavirus disease 2019 pandemic and beyond. The purpose of this work was to create a publicly available metrology resource to assist researchers in evaluating the performance of their medical image analysis ML algorithms. Approach: An interactive decision tree, called MIDRC-MetricTree, has been developed, organized by the type of task that the ML algorithm was trained to perform. The criteria for this decision tree were that (1) users can select information such as the type of task, the nature of the reference standard, and the type of the algorithm output and (2) based on the user input, recommendations are provided regarding appropriate performance evaluation approaches and metrics, including literature references and, when possible, links to publicly available software/code as well as short tutorial videos. Results: Five types of tasks were identified for the decision tree: (a) classification, (b) detection/localization, (c) segmentation, (d) time-to-event (TTE) analysis, and (e) estimation. As an example, the classification branch of the decision tree includes two-class (binary) and multiclass classification tasks and provides suggestions for methods, metrics, software/code recommendations, and literature references for situations where the algorithm produces either binary or non-binary (e.g., continuous) output and for reference standards with negligible or non-negligible variability and unreliability. Conclusions: The publicly available decision tree is a resource to assist researchers in conducting task-specific performance evaluations, including classification, detection/localization, segmentation, TTE, and estimation tasks.

Assessing variability in non-contrast CT for the evaluation of stroke: The effect of CT image reconstruction conditions on AI-based CAD measurements of ASPECTS value and hypodense volume.

Purpose: To rule out hemorrhage, non-contrast CT (NCCT) scans are used for early evaluation of patients with suspected stroke. Recently, artificial intelligence tools have been developed to assist with determining eligibility for reperfusion therapies by automating measurement of the Alberta Stroke Program Early CT Score (ASPECTS), a 10-point scale with > 7 or ≤ 7 being a threshold for change in functional outcome prediction and higher chance of symptomatic hemorrhage, and hypodense volume. The purpose of this work was to investigate the effects of CT reconstruction kernel and slice thickness on ASPECTS and hypodense volume. Methods: The NCCT series image data of 87 patients imaged with a CT stroke protocol at our institution were reconstructed with 3 kernels (H10s-smooth, H40s-medium, H70h-sharp) and 2 slice thicknesses (1.5mm and 5mm) to create a reference condition (H40s/5mm) and 5 non-reference conditions. Each reconstruction for each patient was analyzed with the Brainomix e-Stroke software (Brainomix, Oxford, England) which yields an ASPECTS value and measure of total hypodense volume (mL). Results: An ASPECTS value was returned for 74 of 87 cases in the reference condition (13 failures). ASPECTS in non-reference conditions changed from that measured in the reference condition for 59 cases, 7 of which changed above or below the clinical threshold of 7 for 3 non-reference conditions. ANOVA tests were performed to compare the differences in protocols, Dunnett's post-hoc tests were performed after ANOVA, and a significance level of p < 0.05 was defined. There was no significant effect of kernel (p = 0.91), a significant effect of slice thickness (p < 0.01) and no significant interaction between these factors (p = 0.91). Post-hoc tests indicated no significant difference between ASPECTS estimated in the reference and any non-reference conditions. There was a significant effect of kernel (p < 0.01) and slice thickness (p < 0.01) on hypodense volume, however there was no significant interaction between these factors (p = 0.79). Post-hoc tests indicated significantly different hypodense volume measurements for H10s/1.5mm (p = 0.03), H40s/1.5mm (p < 0.01), H70h/5mm (p < 0.01). No significant difference was found in hypodense volume measured in the H10s/5mm condition (p = 0.96). Conclusion: Automated ASPECTS and hypodense volume measurements can be significantly impacted by reconstruction kernel and slice thickness.

ChatGPT in radiology: A systematic review of performance, pitfalls, and future perspectives.

PURPOSE: The purpose of this study was to systematically review the reported performances of ChatGPT, identify potential limitations, and explore future directions for its integration, optimization, and ethical considerations in radiology applications. MATERIALS AND METHODS: After a comprehensive review of PubMed, Web of Science, Embase, and Google Scholar databases, a cohort of published studies was identified up to January 1, 2024, utilizing ChatGPT for clinical radiology applications. RESULTS: Out of 861 studies derived, 44 studies evaluated the performance of ChatGPT; among these, 37 (37/44; 84.1%) demonstrated high performance, and seven (7/44; 15.9%) indicated it had a lower performance in providing information on diagnosis and clinical decision support (6/44; 13.6%) and patient communication and educational content (1/44; 2.3%). Twenty-four (24/44; 54.5%) studies reported the proportion of ChatGPT's performance. Among these, 19 (19/24; 79.2%) studies recorded a median accuracy of 70.5%, and in five (5/24; 20.8%) studies, there was a median agreement of 83.6% between ChatGPT outcomes and reference standards [radiologists' decision or guidelines], generally confirming ChatGPT's high accuracy in these studies. Eleven studies compared two recent ChatGPT versions, and in ten (10/11; 90.9%), ChatGPTv4 outperformed v3.5, showing notable enhancements in addressing higher-order thinking questions, better comprehension of radiology terms, and improved accuracy in describing images. Risks and concerns about using ChatGPT included biased responses, limited originality, and the potential for inaccurate information leading to misinformation, hallucinations, improper citations and fake references, cybersecurity vulnerabilities, and patient privacy risks. CONCLUSION: Although ChatGPT's effectiveness has been shown in 84.1% of radiology studies, there are still multiple pitfalls and limitations to address. It is too soon to confirm its complete proficiency and accuracy, and more extensive multicenter studies utilizing diverse datasets and pre-training techniques are required to verify ChatGPT's role in radiology.

AAPM WGPE report 394: Simulated error training for the physics plan and chart review.

BACKGROUND: Simulated error training is a method to practice error detection in situations where the occurrence of error is low. Such is the case for the physics plan and chart review where a physicist may check several plans before encountering a significant problem. By simulating potentially hazardous errors, physicists can become familiar with how they manifest and learn from mistakes made during a simulated plan review. PURPOSE: The purpose of this project was to develop a series of training datasets that allows medical physicists and trainees to practice plan and chart reviews in a way that is familiar and accessible, and to provide exposure to the various failure modes (FMs) encountered in clinical scenarios. METHODS: A series of training datasets have been developed that include a variety of embedded errors based on the risk-assessment performed by American Association of Physicists in Medicine (AAPM) Task Group 275 for the physics plan and chart review. The training datasets comprise documentation, screen shots, and digital content derived from common treatment planning and radiation oncology information systems and are available via the Cloud-based platform ProKnow. RESULTS: Overall, 20 datasets have been created incorporating various software systems (Mosaiq, ARIA, Eclipse, RayStation, Pinnacle) and delivery techniques. A total of 110 errors representing 50 different FMs were embedded with the 20 datasets. The project was piloted at the 2021 AAPM Annual Meeting in a workshop where participants had the opportunity to review cases and answer survey questions related to errors they detected and their perception of the project's efficacy. In general, attendees detected higher-priority FMs at a higher rate, though no correlation was found between detection rate and the detectability of the FMs. Familiarity with a given system appeared to play a role in detecting errors, specifically when related to missing information at different locations within a given software system. Overall, 96% of respondents either agreed or strongly agreed that the ProKnow portal and training datasets were effective as a training tool, and 75% of respondents agreed or strongly agreed that they planned to use the tool at their local institution. CONCLUSIONS: The datasets and digital platform provide a standardized and accessible tool for training, performance assessment, and continuing education regarding the physics plan and chart review. Work is ongoing to expand the project to include more modalities, radiation oncology treatment planning and information systems, and FMs based on emerging techniques such as auto-contouring and auto-planning.

Clinical outcomes of outpatient thyroidectomy: A systematic review and single-arm meta-analysis.

BACKGROUND: The aim of this meta-analysis is to investigate the safety of outpatient thyroidectomy based on 24-h and same-day discharge criteria. METHODS: CENTRAL, Embase, PubMed, and Scopus were searched. A meta-analysis of selected studies was performed. The review was registered prospectively with PROSPERO (CRD42022361134). RESULTS: Thirty-one studies met the eligibility criteria, with a total of 74328 patients undergoing thyroidectomy in an outpatient setting based on 24-h discharge criteria. Overall postoperative complications after outpatient thyroidectomies were 5.7% (95%CI: 0.049-0.065; I2 â€‹= â€‹97.3%), consisting of hematoma (0.4%; 95%CI: 0.003-0.005; I2 â€‹= â€‹83.4%), recurrent laryngeal nerve injury (0.4%; 95%CI: 0.003-0.006; I2 â€‹= â€‹93.5%), and hypocalcemia (1.6%; 95%CI: 0.012-0.019; I2 â€‹= â€‹93.7%). The rate of readmission was 1.1% (95%CI: 0.007-0.015; I2 â€‹= â€‹95.4%). Results were similar for same-day criteria. CONCLUSIONS: Our analysis demonstrated that outpatient thyroidectomy is a safe procedure in the management of thyroid disease for selected patients.

Feasibility of a Self-directed Upper Extremity Training Program to Promote Actual Arm Use for Individuals Living in the Community With Chronic Stroke.

Objective: To determine the feasibility of a self-directed training protocol to promote actual arm use in everyday life. The secondary aim was to explore the initial efficacy on upper extremity (UE) outcome measures. Design: Feasibility study using multiple methods. Setting: Home and outpatient research lab. Participants: Fifteen adults (6 women, 9 men, mean age=53.08 years) with chronic stroke living in the community. There was wide range of UE functional levels, ranging from dependent stabilizer (limited function) to functional assist (high function). Intervention: Use My Arm-Remote protocol. Phase 1 consisted of clinician training on motivational interviewing (MI). Phase 2 consisted of MI sessions with participants to determine participant generated goals, training activities, and training schedules. Phase 3 consisted of UE task-oriented training (60 minutes/day, 5 days/week, for 4 weeks). Participants received daily surveys through an app to monitor arm training behavior and weekly virtual check-ins with clinicians to problem-solve challenges and adjust treatment plans. Outcome Measures: Primary outcome measures were feasibility domains after intervention, measured by quantitative study data and qualitative semi-structured interviews. Secondary outcomes included the Canadian Occupational Performance Measure (COPM), Motor Activity Log (MAL), Fugl-Meyer Assessment (FMA), and accelerometry-based duration of use metric measured at baseline, discharge, and 4-week follow-up. Results: The UMA-R was feasible in the following domains: recruitment rate, retention rate, intervention acceptance, intervention delivery, adherence frequency, and safety. Adherence to duration of daily practice did not meet our criteria. Improvements in UE outcomes were achieved at discharge and maintained at follow-up as measured by COPM-Performance subscale (F[1.42, 19.83]=17.72, P<.001) and COPM-Satisfaction subscale (F[2, 28]=14.73, P<.001), MAL (F[1.31, 18.30]=12.05, P<.01) and the FMA (F[2, 28]=16.62, P<.001). Conclusion: The UMA-R was feasible and safe to implement for individuals living in the community with chronic stroke. Adherence duration was identified as area of refinement. Participants demonstrated improvements in standardized UE outcomes to support initial efficacy of the UMA-R. Shared decision-making and behavior change frameworks can support the implementation of UE self-directed rehabilitation. Our results warrant the refinement and further testing of the UMA-R.

The safety and efficacy of radiofrequency ablation in benign pediatric thyroid disease in the US: An initial case series.

Objective: To evaluate the efficacy and safety of radiofrequency ablation (RFA) for benign nonfunctional thyroid nodules or functional lingual thyroid gland in a pediatric population. Methods: Four pediatric patients (four female; mean age 13.50 ± 4.04, range 8-17 years) with either benign thyroid nodules or mildly obstructive lingual thyroid glands were treated with RFA from 2020 to 2021 were evaluated. The inclusion criteria for RFA therapy were (i) age < 18 years; (ii) benign cytopathological results on ultrasound guided fine needle aspiration; (iii) pressure or pain symptoms caused by the thyroid nodules; (iv) dysphagia or obstruction caused by the lingual thyroid tissue; (v) follow up for >6 months with otolaryngology or endocrinology. Results: Two patients had benign non-functioning thyroid nodules and two had mildly obstructive functioning lingual thyroid glands. Mean follow up was 10.75 ± 4.79 months. Each patient underwent one RFA session with no complications. For the patients with thyroid nodules, there was >74% reduction in nodule size at last follow up with improvement in neck swelling and pain. For the patients with lingual thyroid glands, both did not have any other functional thyroid gland identified. Both had visible decrease in size of the gland as visualized transorally with improvement in dysphagia and obstructive symptoms when lying flat. Conclusion: RFA is a safe and effective option for managing benign thyroid nodules and lingual thyroid glands in a pediatric patient population. Level of evidence: 4.

Automated abdominal adipose tissue segmentation and volume quantification on longitudinal MRI using 3D convolutional neural networks with multi-contrast inputs.

OBJECTIVE: Increased subcutaneous and visceral adipose tissue (SAT/VAT) volume is associated with risk for cardiometabolic diseases. This work aimed to develop and evaluate automated abdominal SAT/VAT segmentation on longitudinal MRI in adults with overweight/obesity using attention-based competitive dense (ACD) 3D U-Net and 3D nnU-Net with full field-of-view volumetric multi-contrast inputs. MATERIALS AND METHODS: 920 adults with overweight/obesity were scanned twice at multiple 3 T MRI scanners and institutions. The first scan was divided into training/validation/testing sets (n = 646/92/182). The second scan from the subjects in the testing set was used to evaluate the generalizability for longitudinal analysis. Segmentation performance was assessed by measuring Dice scores (DICE-SAT, DICE-VAT), false negatives (FN), and false positives (FP). Volume agreement was assessed using the intraclass correlation coefficient (ICC). RESULTS: ACD 3D U-Net achieved rapid (< 4.8 s/subject) segmentation with high DICE-SAT (median ≥ 0.994) and DICE-VAT (median ≥ 0.976), small FN (median ≤ 0.7%), and FP (median ≤ 1.1%). 3D nnU-Net yielded rapid (< 2.5 s/subject) segmentation with similar DICE-SAT (median ≥ 0.992), DICE-VAT (median ≥ 0.979), FN (median ≤ 1.1%) and FP (median ≤ 1.2%). Both models yielded excellent agreement in SAT/VAT volume versus reference measurements (ICC > 0.997) in longitudinal analysis. DISCUSSION: ACD 3D U-Net and 3D nnU-Net can be automated tools to quantify abdominal SAT/VAT volume rapidly, accurately, and longitudinally in adults with overweight/obesity.

A needs assessment for simulation in African surgical education.

INTRODUCTION: There is a critical need for comprehensive surgical training in African countries given the unmet surgical burden of disease in this region. Collaborative and progressive initiatives in global surgical education will have the greatest impact on trainees. Little is known about surgical education needs from the perspective of practicing surgeons and trainees in low-middle-income countries (LMICs). Even less is known about the potential role for simulation to augment training. METHODS: A modified Delphi methodology with 2 rounds of responses was employed to survey program directors (PD) and associate program directors (APD) of Pan-African Association of Christian Surgeons (PAACS) general surgery residency programs across eight low-middle-income countries in Africa. 3 PD/APDs and 2 surgical residents participated in semi-structured interviews centered around the role of simulation in training. Descriptive analysis was performed to elicit key themes and illustrative examples. RESULTS: The survey of program directors revealed that teaching residents the psychomotor skills need to perform intracorporeal suturing was both high priority and desired in multiple training sites. Other high priority skills were laparoscopic camera driving and medial visceral rotation. The interviews revealed a specific desire to perform laparoscopic surgery and a need for a simulation curriculum to familiarize staff and trainees with laparoscopic techniques. Several barriers to laparoscopic surgery exist, such as lack of staff familiarity with the equipment, lack of public buy in, and lack of generalizable and adaptable educational modules. Trainees saw utility in the use of simulation to optimize time in the operating room and sought opportunities to improve their laparoscopic skills. CONCLUSION: Faculty and surgical trainees in LMICs have interest in learning advanced surgical techniques, such as laparoscopy. Developing a simulation curriculum tailored to the trainees' local context has the potential to fill this need.

Interstitial lung abnormality evaluated by an automated quantification system: prevalence and progression rate.

BACKGROUND: Despite the importance of recognizing interstitial lung abnormalities, screening methods using computer-based quantitative analysis are not well developed, and studies on the subject with an Asian population are rare. We aimed to identify the prevalence and progression rate of interstitial lung abnormality evaluated by an automated quantification system in the Korean population. METHODS: A total of 2,890 healthy participants in a health screening program (mean age: 49 years, men: 79.5%) with serial chest computed tomography images obtained at least 5 years apart were included. Quantitative lung fibrosis scores were measured on the chest images by an automated quantification system. Interstitial lung abnormalities were defined as a score ≥ 3, and progression as any score increased above baseline. RESULTS: Interstitial lung abnormalities were identified in 251 participants (8.6%), who were older and had a higher body mass index. The prevalence increased with age. Quantification of the follow-up images (median interval: 6.5 years) showed that 23.5% (59/251) of participants initially diagnosed with interstitial lung abnormality exhibited progression, and 11% had developed abnormalities (290/2639). Older age, higher body mass index, and higher erythrocyte sedimentation rate were independent risk factors for progression or development. The interstitial lung abnormality group had worse survival on follow-up (5-year mortality: 3.4% vs. 1.5%; P = 0.010). CONCLUSIONS: Interstitial lung abnormality could be identified in one-tenth of the participants, and a quarter of them showed progression. Older age, higher body mass index and higher erythrocyte sedimentation rate increased the risk of development or progression of interstitial lung abnormality.

Quantitative Computed Tomography Lung COVID Scores with Laboratory Markers: Utilization to Predict Rapid Progression and Monitor Longitudinal Changes in Patients with Coronavirus 2019 (COVID-19) Pneumonia.

Coronavirus disease 2019 (COVID-19), is an ongoing issue in certain populations, presenting rapidly worsening pneumonia and persistent symptoms. This study aimed to test the predictability of rapid progression using radiographic scores and laboratory markers and present longitudinal changes. This retrospective study included 218 COVID-19 pneumonia patients admitted at the Chungnam National University Hospital. Rapid progression was defined as respiratory failure requiring mechanical ventilation within one week of hospitalization. Quantitative COVID (QCOVID) scores were derived from high-resolution computed tomography (CT) analyses: (1) ground glass opacity (QGGO), (2) mixed diseases (QMD), and (3) consolidation (QCON), and the sum, quantitative total lung diseases (QTLD). Laboratory data, including inflammatory markers, were obtained from electronic medical records. Rapid progression was observed in 9.6% of patients. All QCOVID scores predicted rapid progression, with QMD showing the best predictability (AUC = 0.813). In multivariate analyses, the QMD score and interleukin(IL)-6 level were important predictors for rapid progression (AUC = 0.864). With >2 months follow-up CT, remained lung lesions were observed in 21 subjects, even after several weeks of negative reverse transcription polymerase chain reaction test. AI-driven quantitative CT scores in conjugation with laboratory markers can be useful in predicting the rapid progression and monitoring of COVID-19.

Lack of Association of A1C With Postoperative Complications in Children With Type 1 or Type 2 Diabetes.

Not meeting recommended A1C targets may be associated with postoperative complications in adults, but there are no studies reporting on the relationship between preoperative A1C and postoperative complications in children with type 1 or type 2 diabetes. The objective of this study was to determine whether elevated A1C levels were associated with an increased incidence of postoperative complications in children with diabetes presenting for elective noncardiac surgery or diagnostic procedures. It found no such association, suggesting no need to delay elective surgery in children with diabetes until A1C is optimized.

Stereotactic Radiosurgery in the Management of Brain Metastases: A Case-Based Radiosurgery Society Practice Guideline.

Purpose: Brain metastases are common among adult patients with solid malignancies and are increasingly being treated with stereotactic radiosurgery (SRS). As more patients with brain metastases are becoming eligible for SRS, there is a need for practical review of patient selection and treatment considerations. Methods and Materials: Two patient cases were identified to use as the foundation for a discussion of a wide and representative range of management principles: (A) SRS alone for 5 to 15 lesions and (B) a large single metastasis to be treated with pre- or postoperative SRS. Patient selection, fractionation, prescription dose, treatment technique, and dose constraints are discussed. Literature relevant to these cases is summarized to provide a framework for treatment of similar patients. Results: Treatment of brain metastases with SRS requires many considerations including optimal patient selection, fractionation selection, and plan optimization. Conclusions: Case-based practice guidelines developed by the Radiosurgery Society provide a practical guide to the common scenarios noted above affecting patients with metastatic brain tumors.

Delays in definitive endoscopic resection of previously manipulated colorectal polyps as a risk factor for inferior resection outcomes.

BACKGROUND AND AIMS: Manipulation of colorectal polyps by biopsy, incomplete resection, or tattoo placement under the lesion has been shown to cause submucosal fibrosis and associated inferior outcomes. The effect of delays between index manipulation and definitive resection on the incidence of fibrosis is unknown. METHODS: Patients undergoing endoscopic mucosal resection (EMR) of previously manipulated colorectal polyps ≥10 mm from 2016 to 2021 at a tertiary referral center were included. Time from index manipulation to definitive resection and the presence of fibrosis were noted. The effects of fibrosis on EMR outcomes were assessed. RESULTS: Among 221 previously manipulated lesions (180 biopsy, 23 incomplete/failed resection, 1 tattoo under lesion, 17 multiple types of manipulation), 51 (23%) demonstrated fibrosis. Fibrotic lesions were found to have been resected significantly later than nonfibrotic lesions (76 vs 61 days; P = .014). In a multivariate analysis controlling for other predictors of fibrosis, each 2-week delay was associated with a 14% increase in the odds of fibrosis. Fibrotic lesions had inferior outcomes with a lower en-bloc resection rate (8% vs 24%; P = .014) and longer procedure time (71 vs 52 minutes; P < .001). Adverse event and recurrence rates were similar between groups. CONCLUSIONS: Delays in definitive resection of previously manipulated polyps are associated with an increased incidence of fibrosis with time and associated inferior outcomes. Manipulation should be discouraged, and if it occurs, prompt referral and scheduling for definitive resection should be prioritized.

Impact of Biologics and Small-Molecule Agents on Postoperative Complications in IBD: A Systematic Review.

BACKGROUND: Patients with IBD may require colectomy for severe disease unresponsive or refractory to pharmacological therapy. The question of the impact of biologic use on postoperative complications is a topic of active investigation. OBJECTIVE: A systematic literature review was performed to describe the current state of knowledge of the impact of perioperative biologic and tofacitinib use on postoperative complications in patients with IBD. DATA SOURCES: PubMed and Cochrane databases were searched. STUDY SELECTION: Studies between January 2000 and January 2023, in any language, were searched, followed by a snowball search identifying further studies in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. Articles regarding pediatric or endoscopic management were excluded. INTERVENTIONS: Preoperative or perioperative exposure to biologics in IBD was included. MAIN OUTCOME MEASURES: Infectious and noninfectious complications, including anastomotic leaks, surgical site infections, urinary tract infections, pneumonia, sepsis, septic shock, postoperative length of stay, readmission, and reoperation, were the main outcomes measured. RESULTS: A total of 28 studies were included for analysis in this review, including 7 meta-analyses or systematic reviews and 5 randomized studies. Snowball search identified 11 additional studies providing topical information. Overall, tumor necrosis factor inhibitors likely do not increase the risk of postoperative adverse outcomes, while data on other biologics and small-molecule agents are emerging. LIMITATIONS: This is a qualitative review including all study types. The varied nature of study types precludes quantitative comparison. CONCLUSIONS: Although steroids increase postoperative infectious and noninfectious complications, tumor necrosis factor inhibitors do not appear to increase postoperative infectious and noninfectious complications. There is a need for further perioperative data for other agents. See video from symposium .

Comparison of Upper Extremity Function and Daily Use in Individuals with and without Post Stroke Depression.

BACKGROUND: Post-stroke depression (PSD) is a frequent psychiatric complication, however very few studies have investigated its relation to the affected upper extremity (UE) post-stroke. Objective. To compare the affected UE in terms of motor impairment, functional ability, and daily-use in individuals with and without PSD during the first 6 months post-stroke. METHODS: This study analyzed data from a previous cohort; participants were assessed at rehabilitation admission (T1), 6 weeks (T2), and 6 months (T3) post-stroke. At each time point we compared between participants with and without PSD (Geriatric Depression Scale score ≥ 5). The Fugl-Meyer Motor Assessment assessed motor impairment, Action Research Arm Test assessed functional ability, and the Rating of Everyday Arm-Use in the Community and Home assessed daily-use. Independence in daily activities and cognition were also assessed. RESULTS: A total of 116 participants were recruited, 38% had PSD at T1. No significant differences were found between groups at T1 and T2. However, significant differences (z = -5.23 to -2.66, p < .01) were found between groups for all UE measures at T3; participants with PSD had lower motor and functional ability and less daily hand-use than participants without PSD. At T3 participants with PSD were also less independent in daily-living. CONCLUSIONS: PSD is associated with greater UE motor, functional, and daily-use disability at 6 months post-stroke. Our findings underscore the negative impact of PSD on UE during the crucial transition period when individuals return home and integrate back into the community. Further research is needed to delineate the effect of change in PSD status on UE outcomes post stroke.

Effect of vicarious discrimination on race-based stress symptoms among Asian American young adults during the COVID-19 pandemic.

OBJECTIVE: The COVID-19 pandemic has led to a rise in anti-Asian hate crimes in the United States. Previous work has established that experiencing racism increases one's dysfunctional anxiety and avoidance actions-key symptoms of race-based stress symptoms. However, the psychological impact of vicarious, or secondhand, discrimination (witnessing racism targeting one's own race group) remains less understood. METHOD: We tested the hypothesis that higher reported vicarious discrimination would be associated with higher levels of race-based stress symptoms reported by Asian American young adults (n = 135) during the pandemic using a cross-sectional analysis of the COVID-19 Adult Resilience Experiences Study (CARES). Starting in April 2020, CARES assessed sociodemographic characteristics and key psychometric scales in young adults through three waves of online surveys. RESULTS: Our multiple regression analysis showed vicarious discrimination significantly predicted race-based stress symptoms, even after controlling for direct discrimination (p < .01). This association remained significant after controlling for age, gender, subjective childhood family social status, and preexisting psychiatric disorders (p < .01). Our results demonstrate that regardless of the effect that direct discrimination might have on race-based stress symptoms, witnessing discrimination against members of one's own racial group is significantly associated with increased race-based stress symptoms (b = 2.68, p < .01). Social media was the most common source of vicarious discrimination, with one out of three participants in our sample reporting nearly daily exposure. CONCLUSION: Providers should intentionally create a space within the therapeutic setting to discuss the effects of vicarious discrimination.

Patient-Reported Outcomes to Describe Global Health and Family Relationships in Pediatric Weight Management.

Background: Patient-reported outcomes (PROs) can assess chronic health. The study aims were to pilot a survey through the PEDSnet Healthy Weight Network (HWN), collecting PROs in tertiary care pediatric weight management programs (PWMP) in the United States, and demonstrate that a 50% enrollment rate was feasible; describe PROs in this population; and explore the relationship between child/family characteristics and PROs. Methods: Participants included 12- to 18-year-old patients and parents of 5- to 18-year-olds receiving care at PWMP in eight HWN sites. Patient-Reported Outcomes Measurement Information System (PROMIS®) measures assessed global health (GH), fatigue, stress, and family relationships (FR). T-score cut points defined poor GH or FR or severe fatigue or stress. Generalized estimating equations explored relationships between patient/family characteristics and PROMIS measures. Results: Overall, 63% of eligible parents and 52% of eligible children enrolled. Seven sites achieved the goal enrollment for parents and four for children. Participants included 1447 children. By self-report, 44.6% reported poor GH, 8.6% poor FR, 9.3% severe fatigue, and 7.6% severe stress. Multiple-parent household was associated with lower odds of poor GH by parent proxy report [adjusted odds ratio (aOR) 0.69, 95% confidence interval (CI) 0.55-0.88] and poor FR by self-report (aOR 0.36, 95% CI 0.17-0.74). Parents were significantly more likely to report that the child had poor GH and poor FR when a child had multiple households. Conclusions: PROs were feasibly assessed across the HWN, although implementation varied by site. Nearly half of the children seeking care in PWMP reported poor GH, and family context may play a role. Future work may build on this pilot to show how PROs can inform clinical care in PWMP.
