Screening, brief intervention, and referral to treatment for tobacco consumption, alcohol misuse, and physical inactivity: an equity-informed rapid review

OBJECTIVE

This rapid review systematically synthesizes evidence of the effectiveness of the Screening, Brief Intervention, and Referral (SBIR/T) approach for tobacco use, alcohol misuse, and physical inactivity.

STUDY DESIGN

This was a rapid review.

METHODS

We searched primary studies between 2012 and 2022 in seven electronic databases. The search strategy used concepts related to alcohol-related disorders, intoxication, cigarette, nicotine, physical activity, exercise, sedentary, screening, therapy, and referral. We reviewed both title/abstract and full-text using a priori set inclusion and exclusion criteria to identify the eligible studies. We appraised study quality, extracted data, and summarized the characteristics of the included studies. We applied health equity lenses in the synthesis.

RESULTS

Of the 44 included studies, most focused on alcohol misuse. SBIR/T improved patients' attitudes toward alcohol behavior change, improved readiness and referral initiation for change, and effectively reduced alcohol consumption. Few studies pertained to smoking and physical inactivity. Most studies on smoking demonstrated effectiveness pertaining to patients' acceptance of referral recommendations, improved readiness and attempts to quitting smoking, and reduced or cessation of smoking. Findings were mixed about the effectiveness of SBIR/T in improving physical activity. Minimal studies exist on the impacts of SBIR/T for these three risk factors on healthcare resource use or costs. Studies considering diverse population characteristics in the design and effectiveness assessment of the SBIR/T intervention are lacking.

CONCLUSIONS

More research on the impacts of SBIR/T on tobacco use, alcohol misuse, and physical inactivity is required to inform the planning and delivery of SBIR/T for general and disadvantaged populations.

Structure guided mutagenesis of Henipavirus Receptor Binding Proteins reveals molecular determinants of receptor usage and antibody binding epitopes

Nipah virus (NiV) is a highly lethal, zoonotic henipavirus (HNV) that causes respiratory and neurological signs and symptoms in humans. Similar to other paramyxoviruses, HNVs mediate entry into host cells through the concerted actions of two surface glycoproteins: a receptor binding protein (RBP) that mediates attachment and a fusion glycoprotein (F) that triggers fusion in an RBP-dependent manner. NiV uses ephrin-B2 (EFNB2) and ephrin-B3 (EFNB3) as entry receptors. Ghana virus (GhV), a novel HNV identified in a Ghanaian bat, use EFNB2 but not EFNB3. In this study, we employ a structure-informed approach to identify receptor interfacing residues and systematically introduce GhV-RBP residues into a NiV-RBP backbone to uncover the molecular determinants of EFNB3 usage. We reveal two regions that severely impair EFNB3 binding by NiV-RBP and EFNB3-mediated entry by NiV pseudotyped viral particles. Further analyses uncovered two point mutations (NiVN557SGhV and NiVY581TGhV) pivotal for this phenotype. Moreover, we identify NiV interaction with Y120 of EFNB3 as important for usage of this receptor. Beyond these EFNB3-related findings, we reveal two domains that restrict GhV binding of EFNB2, identify the HNV-head as an immunodominant target for polyclonal and monoclonal antibodies, and describe putative epitopes for GhV and NiV-specific monoclonal antibodies. Cumulatively, the work presented here generates useful reagents and tools that shed insight to residues important for NiV usage of EFNB3, reveals regions critical for GhV binding of EFNB2, and describes putative HNV antibody binding epitopes.

Employment and emotional well-being in veterans with mental illness

The purpose of this study is to examine group differences between employed and unemployed Veterans with mental illnesses utilizing the National Institutes of Health (NIH) emotion toolbox factors including negative affect, psychological well-being, stress, and social relationships. Data was collected from three samples from 2018 to 2020. The first sample (Sample 1) is 156 Veterans with mental illness from Amazon MTurk; the second sample (Sample 2), recruited from a higher education institution, is 232 veterans with posttraumatic stress disorder (PTSD) symptoms; and the final sample (Sample 3), recruited from a higher education institution, is 129 Veterans with disabilities, including psychiatric disabilities. Independent-samples t-tests were carried out to test our objectives. Sample 1 results revealed that employed Veterans with mental illnesses had lower levels of depression and stress and higher levels of positive emotion, life satisfaction, meaning in life, and social relationships compared to unemployed Veterans. Sample 2 results revealed that employed Veterans with PTDS symptoms had lower levels of stress and higher levels of positive emotion and lower levels of stress compared to unemployed Veterans with PTSD symptoms. Sample 3 results revealed that employed Veterans with disabilities including psychiatric disabilities had lower levels of depression and higher levels of positive emotion and social relationships. Our findings are consistent with the previous research documenting that employment plays a central role in optimal psychological and physical health in both civilians and veterans.

Integrating a Tool to Automatically Determine Necessity of Online Adaptive Replanning

PURPOSE/OBJECTIVE(S)

As online adaptive replanning (OLAR) is labor-intensive and time-consuming, it's desirable to determine when OLAR is necessary before OLAR is initiated. We have previously reported a novel method to automatically determine the necessity of OLAR using machine leaning algorithms based on the structural similarity maps (SSIM) and wavelet texture maps (WMT) extracted from the daily MRI during MR-guided adaptive radiation therapy (MRgART). This study aims to integrate this method into a commercial software platform that has been used during our routine MRgART.

MATERIALS/METHODS

The method of automatically determining the necessity of OLAR based on daily MRI was implemented and integrated into the software platform through a specifically developed workflow. The obtained workflow was tested using 25 daily MRI sets acquired from 5 patients with pancreatic cancer in the following procedure: 1) rigidly registering the daily and reference MRIs, 2) identifying the region enclosed by the 50-100% iso-dose surfaces on the daily MRI by transferring the iso-dose surfaces from the reference to the daily MRIs, 3) launching our in-house codes to calculate significant changes in textures extracted from SSIM and WMT maps, 4) inputting the feature values into the pre-trained classifier models for SSIM and WMT, and 5) outputting results considering the WMT based prediction as the primary indicator and the SSIM-based as the secondary (validation) indicator on whether OLAR is needed for the daily MRI.

RESULTS

The execution of the developed workflow was fast and can be used to streamline the process. It provides the ability to scroll through the images for better decision making while providing quantitative prediction within 30-38 seconds. Eighty percent of the daily MRIs required OLAR. The SSIM map displayed was able to successfully captured the areas of similarity between the reference and daily MRIs and the WMT prediction agreed with the prediction class.

CONCLUSION

The integration of the prediction method for automatically determining the necessity of OLAR based on two independent machine learning classifiers into a commercially available software is feasible and can be used to streamline the process of MRgART. With larger verification studies, this workflow-based tool may be developed into a generalized tool that assist in OLAR using different platforms.

Resilience as a Moderator in the Relationship between Disability Related Stress and Community Participation in Individuals with Multiple Sclerosis

Resilience can be defined as one's ability to maintain or return to relatively stable psychological and physical functioning despite stressful life events and adversity. For people with multiple sclerosis (MS), building resilience has been shown to contribute to enhanced positive rehabilitation and mental health outcomes. However, there is no literature examining the role of resilience influencing the relationship between disability-related stress and community participation in individuals with MS. The present study aimed to examine the moderating role of resilience between disability-related stress and community participation among people with MS. Our findings suggested that the effect of disability-related stress on community participation was influenced by resilience. Interventions targeting resilience may help individuals effectively cope with MS and increase community participation in meaningful life situations.

Uncertainty in phosphorus fluxes and budgets across the U.S. long-term agroecosystem research network

Phosphorus (P) budgets can be useful tools for understanding nutrient cycling and quantifying the effectiveness of nutrient management planning and policies; however, uncertainties in agricultural nutrient budgets are not often quantitatively assessed. The objective of this study was to evaluate uncertainty in P fluxes (fertilizer/manure application, atmospheric deposition, irrigation, crop removal, surface runoff, leachate) and the propagation of these uncertainties to annual P budgets. Data from 56 cropping systems in the P-FLUX database, which spans diverse rotations and landscapes across the U.S. and Canada, were evaluated. Results showed that across cropping systems, average annual P budget was 22.4 kg P ha^-1 (range = -32.7 to 340.6 kg P ha^-1 ), with an average uncertainty of 13.1 kg P ha^-1 (range = 1.0 to 87.1 kg P ha^-1 ). Fertilizer/manure application and crop removal were the largest P fluxes across cropping systems and, as a result, accounted for the largest fraction of uncertainty in annual budgets (61 and 37%, respectively). Remaining fluxes individually accounted for <2% of the budget uncertainty. Uncertainties were large enough that determining whether P was increasing, decreasing, or not changing was inconclusive in 39% of the budgets evaluated. Findings indicate that more careful and/or direct measurements of inputs, outputs, and stocks are needed. Recommendations for minimizing uncertainty in P budgets based on the results of the study were developed. Quantifying, communicating, and constraining uncertainty in budgets among production systems and multiple geographies is critical for engaging stakeholders, developing local and national strategies for P reduction, and informing policy.

Validation of the multiple disability multidimensional attitudes scale toward persons with disabilities

PURPOSE/OBJECTIVE

This study investigated the psychometric properties of a Multiple Disability Multidimensional Attitudes Scale Toward Persons with Disabilities (MD-MAS), focusing on four types of disabilities: anxiety disorder, autism spectrum disorder (ASD), blindness, and schizophrenia. We developed new vignettes describing the situation of interacting with an individual with each type of disability.

RESEARCH METHOD/DESIGN

We recruited 991 participants from a crowdsourcing data collection tool (i.e., Prolific). Participants were randomly assigned to one of four online surveys depending on the disability type. Five MAS models were selected from the previous literature to conduct confirmatory factor analyses (CFA).

RESULTS

CFA supported the German model of MAS with a four-factor structure (i.e., calm, negative affect, positive cognition, behavioral avoidance) as a good fit for the MD-MAS for four disability types. High internal consistency was found for four subscales across the disability types.

CONCLUSIONS/IMPLICATIONS

This study modified the original MAS to assess attitudes toward persons with different types of disabilities. The adequate reliability and fit of the factor structure of the MD-MAS same across the four disability types allow researchers to compare attitudes based on disability types. This will provide significant implications for research and practice in understanding the nature of different attitudes by disability types.

Initial phase establishment of an in vitro method for developmental neurotoxicity test using Ki-67 in human neural progenitor cells

Building a precise alternative neurotoxicological test is of great importance to respond to societal and ethical requirements. In this study, a new developmental neurotoxicity test (DNT) was established with the human neural progenitor cell line. ReNcell CX cells were exposed to neurotoxic chemicals (aphidicolin, hydroxyurea, cytosine arabinoside, 5-fluorouracil, and ochratoxin A) or non-neurotoxic chemicals (sodium gluconate, sodium bicarbonate, penicillin G, and saccharin). Propidium iodide (PI) was used to evaluate cell viability. BrdU and Ki-76 were employed to determine cell proliferation. Based on the cell viability and proliferation, mathematical models were built by linear discriminant analysis. Furthermore, the neurotoxic-considered chemicals inhibited cell cycle progression at the protein level, supporting the biomolecular rationale for the predictive model. Overall, these results show that the new test method can be used to determine the potential developmental neurotoxicants or new drug candidates.

Integrating EM and Patch-seq data: Synaptic connectivity and target specificity of predicted Sst transcriptomic types

Neural circuit function is shaped both by the cell types that comprise the circuit and the connections between those cell types ¹ . Neural cell types have previously been defined by morphology ^{2, 3} , electrophysiology ^{4, 5} , transcriptomic expression ^6-8 , connectivity ^9-13 , or even a combination of such modalities ^14-16 . More recently, the Patch-seq technique has enabled the characterization of morphology (M), electrophysiology (E), and transcriptomic (T) properties from individual cells ^17-20 . Using this technique, these properties were integrated to define 28, inhibitory multimodal, MET-types in mouse primary visual cortex ²¹ . It is unknown how these MET-types connect within the broader cortical circuitry however. Here we show that we can predict the MET-type identity of inhibitory cells within a large-scale electron microscopy (EM) dataset and these MET-types have distinct ultrastructural features and synapse connectivity patterns. We found that EM Martinotti cells, a well defined morphological cell type ^{22, 23} known to be Somatostatin positive (Sst+) ^{24, 25} , were successfully predicted to belong to Sst+ MET-types. Each identified MET-type had distinct axon myelination patterns and synapsed onto specific excitatory targets. Our results demonstrate that morphological features can be used to link cell type identities across imaging modalities, which enables further comparison of connectivity in relation to transcriptomic or electrophysiological properties. Furthermore, our results show that MET-types have distinct connectivity patterns, supporting the use of MET-types and connectivity to meaningfully define cell types.

Positive Organizational Psychology Factors as Serial Multiple Mediators of the Relationship between Organization Support and Job Satisfaction Among Peer Support Specialists

BACKGROUND

Research has demonstrated the effectiveness of peer support specialists in helping people with severe mental illness increase community tenure, decrease hospitalization, boost treatment satisfaction, improve social functioning, and increase quality of life.

OBJECTIVE

The purpose of the present study was to evaluate positive organizational psychology constructs as serial multiple mediators of the relationships between perceived organizational support and job satisfaction among peer support specialists.

METHODS

One hundred and twenty-one peer support specialists from the Texas statewide peer certification training programs and the National Association of Peer Supporters participated in the present study. These peer support specialists completed an online survey composed of self-report measures related to perceived organizational support, positive organizational psychology factors, and job satisfaction. A serial multiple mediation (SMMA) analysis was conducted to evaluate autonomous motivation to work, work engagement, and organizational commitment as mediators of the relationship between perceived organizational support and job satisfaction.

RESULTS

The SMMA model accounted for 49% of the variation in job satisfaction scores (R² =. 49, f² = 0.96 [> 0.35], a large effect size). Autonomous motivation to work, work engagement, and organizational commitment were significantly associated with job satisfaction after controlling for the effect of perceived organizational support.

CONCLUSIONS

Perceived organizational support increased autonomous motivation to work, work engagement, organizational commitment, and job satisfaction. Peer support specialists are integral members of the interdisciplinary mental health treatment team. Leaders of community-based mental health and rehabilitation agencies who are committed to hire and retain peer support specialists must provide strong organizational support and develop interventions to increase peer support specialists' autonomous motivation to work, work engagement, and organizational commitment as a job retention and career development strategy.

Employer Practices for Integrating People With Disabilities Into the Workplace: A Scoping Review

Background:Workplace inclusion contributes to job satisfaction and innovation. Integrating people with disabilities (PWDs) improves productivity, morale, creativity, problem-solving, and commitment. Previous evidence revealed that employers are ambivalent about integrating PWDs. There remains a paucity of literature that examines demand-side employment practices of integrating PWDs in the workplace.

Objective:The present study comprehensively reviewed the demand-side employment literature to identify existing practices used to improve the integrating PWDs in the workplace.

Methods:A scoping review was employed. Articles were retrieved from PsycInfo, Academic Search, Web-science, American Business Index, and ProQuest Dissertations & Theses Global and published in English from January 1985 to August 2017.

Findings:The scoping review yielded 19 articles. Three themes were identified as common and effective employer practices, including (a) policy and allegation, (b) internal and external partnerships, and (c) organizational top-down management diversity support.

Conclusion:The findings of this scoping review provide collective information for integrating PWDs in the workplace. Findings shed some light on employer and rehabilitation counselors to engage and assist employers in promoting an inclusive workplace climate.

The relationship between meaning in life and apathy in people with Parkinson's disease: a cross-sectional analysis

BACKGROUND

Apathy remains a common and problematic neuropsychiatric feature associated with Parkinson's disease resulting in reductions in health-related quality of life, and effective treatments remain elusive. Meaning in life (MIL) has been implicated in a variety of positive health outcomes, and this study assesses the relationship between apathy and MIL while hoping to identify a potential new interventional target.

METHODS

A cross-sectional sample of 237 PwPD completed surveys to evaluate MIL and a variety of non-motor symptoms (NMS), and a hierarchical regression analysis was conducted to evaluate relationships of interest.

RESULTS

Correlational analysis indicated the presence of meaning in life was statistically negatively and moderately to strongly correlated with apathy (r = - 0.60, p < .001). Hierarchical regression analysis results showed that presence of meaning in life explained a total of 48% of variance in apathy. More specifically, the presence of meaning in life (β = - 0.43, p < .001) was associated with apathy after controlling for sociodemographic and other potentially confounding variables.

CONCLUSIONS

This study demonstrates the significant negative relationship between MIL and apathy. Considering the lack of effective treatments for apathy, which is one of the most disabling symptoms affecting PwPD, identifying a potential target for intervention is exciting. MIL has the potential to offer clinicians a novel intervention to provide a much-needed treatment option to improve both apathy and HRQoL.

Characteristics of individuals with disabilities receiving transportation services in vocational rehabilitation

BACKGROUND: Adequate, accessible public transportation is essential to fully address social and economic disparities that exist among individuals with disabilities. Despite removal of many physical barriers within transportation systems, significant barriers to public transportation for people with disabilities are still widespread. OBJECTIVE: Transportation is commonly cited as an obstacle to employment for individuals with disabilities, and as a result, a thorough analysis of specific factors influencing the use of public transportation by individuals with disabilities is necessary to fully understand patterns of use. METHOD: The current study used a national sample of individuals with disabilities in pursuit of employment to investigate characteristics that predict the receipt of transportation services by vocational rehabilitation personnel. RESULTS: Results indicate individuals who were not employed, who were receiving welfare and/or TANF, who were homeless, who were living in rehabilitation facilities, and/or living in substance abuse treatment centers were more likely to receive transit services from vocational rehabilitation programs. Also, individuals with substance use problems, mental health disorders, HIV/AIDS or other immune deficiency disorders, and/or people from racial or ethnic minority backgrounds were more likely to receive transit service support from vocational rehabilitation programs. CONCLUSION: Improvement in transportation services for individuals with disabilities is needed on a systems and individual level. State rehabilitation counselors can evaluate the extent high-risk clients identified in this study can benefit from transit services as well as other wrap around services that can improve their engagement in VR services leading to better employment outcomes.

Promoting Well-Being in Individuals With Autism: Applying Positive Psychology in Rehabilitation Counseling

Positive psychology is a subdomain that addresses the importance of human strengths and personal assets in individuals’ well-being. The principles of positive psychology align with the philosophy of rehabilitation counseling by emphasizing individuals’ strengths to promote psychosocial adjustment to disability. Considering the intersection between positive psychology and rehabilitation counseling, applying the positive psychology framework to rehabilitation counseling will be a promising foundation for improvement in services and outcomes. As the number of individuals on the autism spectrum increases, more innovative services are needed to keep abreast of their needs. This article discusses how positive psychology can be applied to the population of individuals with autism spectrum disorder (ASD) and explores possible practices that can be replicated by practitioners to provide quality services for this emerging disability population. Implications for education and research are also discussed.

Emerging vocational rehabilitation strategies for people with diabetes mellitus

BACKGROUND: People with diabetes mellitus constitute an emerging vocational rehabilitation (VR) consumer population. OBJECTIVE: The objective of this article is to (a) describe the characteristics and needs of Americans with diabetes mellitus, (b) examine the often devastating effects that this highly prevalent disease of the endocrine system has on employment and career development, and (c) suggest strategies that rehabilitation professionals can use to improve VR services and outcomes. METHOD: Following an overview of the etiology, incidence, prevalence, and impact of this high incidence endocrinological disease, the authors present strategies to meet the service and support needs of Americans with diabetes mellitus across the phases of the VR process. RESULTS: The importance of individualized case planning, employer consultation, workplace accommodations, interface with medical and mental health professionals, and adherence to self-care and symptom management regimens is emphasized throughout the article. CONCLUSION: Diabetes mellitus is an emerging disability that can affect people of any age, one that disproportionally affects people of color and people who live in poverty. Rehabilitation professionals must be prepared to meet the service needs of this growing clientele.

The association between hope and employment among individuals with multiple sclerosis: A hierarchical logistic regression model

BACKGROUND

Most people with multiple sclerosis (MS) are employed at the time of their diagnosis; however, due to the unpredictable nature of MS, most exit the workforce shortly thereafter. A plethora of research has examined factors that negatively affect employment outcomes for people with MS. However, little is known about how hope, a modifiable positive psychology factor, affects employment.

OBJECTIVE

This study examined the role of hope and its association with employment outcomes for people with MS.

METHODS

Two-hundred and fifty-five adults with MS (mean ± SD age, 45.45 years ± 10.28) completed surveys about their MS, employment, disability-related stress, and hope. A three-step hierarchical logistic regression was conducted to examine the extent to which hope explains the variance in employment, over and above demographic and disability related covariates.

RESULTS

The final model explained 28% of the variance in employment, suggesting that the model was able to distinguish people with MS who were employed versus those who were unemployed. Higher levels of hope were associated with an increased probability of being employed (OR = 4.65; 95% CI [1.98, 10.92]).

CONCLUSION

This study supports that hope is associated with favorable employment outcomes for people with MS. Persons with MS may benefit from working with rehabilitation professionals to enhance their hope, and this study provides a foundation for the development of hope-based interventions to improve employment outcomes among this population.

Stent expansion evaluated by optical coherence tomography and subsequent outcomes

Background

Regarding stent expansion indexes, previous optical coherence tomography (OCT) studies have shown minimal stent area (MSA) to be most predictive of adverse events.

Purpose

We sought to evaluate the impact of various stent expansion indexes by post-stent OCT on long-term clinical outcomes, and hence to find OCT-defined optimal stent expansion criteria.

Methods

Of the patients registered in the Yonsei OCT registry, a total of 1071 patients with 1123 native coronary artery lesions treated with new-generation drug-eluting stents under the OCT guidance and analyzable final post-stent OCT were included. Stent expansion indexes and different suboptimal stent expansion criteria were evaluated for their association with device-oriented clinical endpoints (DoCE) including cardiac death, target vessel-related myocardial infarction (TVMI) or stent thrombosis, and target lesion revascularization. Major safety events (MSE) included cardiac death, TVMI or stent thrombosis.

Results

The median follow-up period was 40.6 (interquartile range 22.0–50.0) months. As a continuous variable, MSA, adaptive volumetric stent expansion (stent volume/adaptive reference lumen volume) and overall volumetric stent expansion (stent volume/post-stent lumen volume) were significantly predictive of DoCE. As a categorical criteria, MSA &lt;5.0 mm2 (hazard ratio [HR] 3.80; 95% confidence interval [CI] 1.53–9.45), MSA/distal reference lumen area &lt;90% (HR 2.13; 95% CI 1.10–4.14), and overall volumetric stent expansion ≥96.6% (HR 2.38; 95% CI 1.09–5.22) were independently associated with DoCE after adjusting for confounders, and a total malapposition volume ≥7.0 mm3 (HR 3.38; 95% CI 1.05–10.93) was linked to MSE.

Conclusions

This OCT study highlights that sufficient stent expansion to achieve adequate absolute MSA and relative MSA by distal reference lumen area and alleviate significant malapposition is important to improve clinical outcome, but overall stent overexpansion may have deleterious effect.

Atrial fibrillation detection in ambulatory patients using a smart ring powered by deep learning analysis of continuous photoplethysmography monitoring

Background

Atrial fibrillation (AF) detection could be effective with photoplethysmography (PPG) signal monitoring by a wearable device.

Purpose

We aimed to validate the performance of AF detection among ambulatory patients who underwent electrical cardioversion for AF using a smart ring capable of continuous PPG monitoring and deep learning analysis.

Methods

In this prospective single-arm study, participants who underwent successful electrical cardioversion for AF were enrolled. The participants equipped a smart ring (CardioTracker, Sky Labs Inc., Seongnam, Republic of Korea) after the electrical cardioversion. The smart ring then continuously monitored PPG over 14 days to detect AF recurrence. The smart ring alarmed AF episodes based on deep learning analysis of PPG. The participants were asked to measure at least three daily ECGs using the smart ring to validate AF recurrence detected by PPG. All ECG snapshots were recorded along with lead I and saved with simultaneous PPG. ECG data were examined by the three cardiologists independently (SK, SRL, and EKC). The monitoring time, analyzable proportions of monitored signals, detection rates of AF episodes, and the diagnostic performance of PPG-based deep learning were evaluated. At the end of the monitoring, a survey on the use of the smart ring was performed.

Results

A total of 35 participants (mean age 58.9 years, male 74.3%) were enrolled. Figure 1 illustrates an example of PPG monitoring and PPG-ECG snapshots by the smart ring. The study participation period was a median of 14 days and the wearing time of the smart ring was a median of 9.2 days (IQR 7.1–11.5 days). Signal artifacts during daily activity decreased the analyzable proportions of monitored PPG by 68.5%. Irregular pulse episodes were detected by the smart ring in 29 (82.9%) participants after a median of 1 day from the cardioversion (Figure 2). A total of 2532 PPG-ECG snapshots were acquired and 1623 (64.1%) were interpretable by both the cardiologists (using ECG) and the deep learning analysis (using PPG). Comparing PPG by simultaneous ECG, the performance of AF detection by the smart ring was 98.7% for sensitivity, 97.8% for specificity, 2.2% for false positives, and 1.3% for false negatives (Figure 2). After using the smart ring, 76.9% of the participants responded that they had no discomfort in using the smart ring in daily activity and another 76.9% responded that it was helpful to monitor their disease.

Conclusion

Despite the signal artifacts during daily activity, AF detection with PPG monitoring by a smart ring could be effective for AF screening among ambulatory patients.

COVID-19 stress, resilience, and job loss concerns in people with chronic conditions and disabilities

BACKGROUND: People experience higher levels of psychological distress during times of crisis, such as the current COVID-19 pandemic. Resilience is a psychological resource that helps people to recover from adverse events. OBJECTIVE: The purpose of this study was to determine the effects of resilience on COVID-19-related stress and worry about job loss in people with chronic conditions and disabilities (PwCID). METHODS: The Perceived Stress Questionnaire -8 (PSQ-8) and the Brief Resilience Scale were used to measure COVID-19-related stress and resilience, respectively. Demographics were also assessed. A two-step hierarchical regression and binary regression analyses were conducted. RESULTS: A moderate amount of perceived stress and resilience with mean scores of 2.45 (SD = 0.69; range 1-4) and 3.17 (SD = 0.98; range 1-5), respectively, were found among the 269 participants. Resilience (β=-0.44, p <  0.001) was significantly associated withCOVID-19-related stress after controlling for demographic variables. Results also revealed that those with higher resilience scores had lower probability to worry about job loss. CONCLUSION: PwCID who have higher scores on resilience reported lower levels of COVID-19-related stress. Resilience can be cultivated among PwCID for better psychological outcomes during times of crisis. Vocational rehabilitation counselors can implement strategies to improve resilience in PwCID.

Relations among gratitude, adaptation to disability, and flourishing among adults with disabilities: A longitudinal mediation model

PURPOSE/OBJECTIVE

Flourishing, a primary outcome of rehabilitation psychology, is understudied among adults with disabilities. Gratitude has emerged as an individual strength that is both malleable and robust in predicting flourishing and adaptation to disability. The purpose of this study was to assess the influence of gratitude on flourishing over time and to analyze the potential mediating role of adaptation to disability on this relationship for a group of adults with disabilities.

RESEARCH METHOD/DESIGN

Data were collected at 3 time points over 21 months (N = 429). A single mediator model with external demographic variables was tested to determine the relationship of gratitude (Time 1) with adaptation to disability (Time 2) and flourishing (Time 3). Approximately 40% of the initial sample was retained across all time points.

RESULTS

Gratitude predicted later flourishing and adaptation to disability accounted for a significant portion of this relationship, accounting for 27% of the total effect.

CONCLUSIONS/IMPLICATIONS

Results of this single mediator model indicate that adaptation to disability serves as a partial mediator of the relationship between gratitude and flourishing, with both gratitude and adaptation to disability having a significantly positive influence on flourishing. Understanding gratitude's influence on later adaptation and flourishing provides data to inform rehabilitation psychology interventions. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Examining the Role of Resilience and Hope in Grit in Multiple Sclerosis

The purpose of this study was to examine the effects of resilience and hope on grit when controlling for demographic covariates, depression, and anxiety in people with multiple sclerosis (MS). This was a cross-sectional study with a sample of 348 participants with MS. Descriptive statistics were performed to examine participants' demographic characteristics. A three-step hierarchical regression analysis was conducted to evaluate the extent to which resilience and hope explain the unique variance in grit while controlling for demographic covariates, depression, and anxiety. Findings suggested that resilience and hope explained a significant amount of variance in grit when controlling for demographic covariates, depression, and anxiety. Furthermore, higher resilience and hope scores were associated with higher grit scores. Given that resilience, hope, and grit are modifiable, rehabilitation and mental health professionals (e.g., psychologists, psychiatrists, rehabilitation counselors) can integrate strength-based interventions into their practices to bolster resilience, hope, and grit in people with MS. Our paper also has implications for interdisciplinary research and clinical practice.

POS0763 A MULTIMODAL MAGNETIC RESONANCE IMAGING STUDY OF COGNITIVE FUNCTION IN SYSTEMIC LUPUS ERYTHEMATOSUS: A MACHINE LEARNING APPROACH

Background

Systemic lupus erythematosus (SLE) is a multisystem autoimmune disorder that can affect the central nervous system. Cognitive dysfuncion is the most common neuropsyhiatric event in SLE patients, yet it is also one of the hardest to diagnose.

Objectives

To investigate if multimodal imaging to assess anatomical magnetic resonance imaging (MRI) abnormalities in the brains of SLE patients can predict cognitive function.

Methods

Subjects underwent voxel-based morphometry (VBM), magnetization transfer imaging (MTI), and dynamic contrast-enhanced (DCE) MRI. Automated Neuropsychological Assessment Metrics (ANAM) was used to assess cognitive function in this cross-sectional study and the primary measure was the total throughput score (TTS). TTS is the total of the throughput scores for each of the 8 ANAM subtests: (i) code substitution learning (CSL); (ii) code substitution immediate (CSI); (iii) code substitution delayed (CSD); (iv) spatial processing (SP); (v) matching to sample (MSP); (vi) running memory continuous performance test (CPT); (vii) mathematical processing (MTH) and (viii) memory search (MS). Olfactory assessment was done using the University of Pennsylvania Smell Identification Test. We used a machine learning-based model (i.e. GLMnet) to predict TTS. Subjects with active SLE disease or above 40 years old were excluded.

Results

Thirty SLE patients [26 female, 32.0 (26.8-37.0) years] without clinically overt neuropsychiatric manifestations and 10 healthy controls (HCs) [9 females, 27.0 (23.0-31.5) years] were enrolled in this study. Both groups had comparable cognitive and olfactory functions. No significant differences were observed in VBM, MTR, olfactory blub and tract (OBT) volume in SLE patients compared to HCs. We observed increased blood-brain barrier (BBB) permeability parameters (Ktrans and PS) in several regions of SLE patients. DCE-MRI perfusion parameters such as perfusion (F) and vp but not permeability measures were associated with TTS. In particular, F right amygdala correlated with TTS in SLE patients (r = 0.636, FDR p < 0.05) (Table 1). Using GLMnet, we trained a multimodal MRI model comprising of VBM, MTR, DCE-MRI and OBT volume parameters to predict TTS in SLE patients (r = 0.998, p < 0.0005) (Figure 1).

Conclusion

These findings suggest that the BBB may be affected early in the course of cognitive dysfunction, even preceding detectable changes in other MRI sequences and machine learning algorithms can be used to predict TTS measures, even in asymptomatic SLE patients.

Measuring COVID-19 vaccine hesitancy among college students with disabilities: Sociodemographic and psychological correlates of COVID-19 vaccine hesitancy

Objective: The purpose of the study was to explore characteristics of vaccine hesitancy and behaviors among college students with disabilities. Participants and Methods: Participants consisted of 105 college students with disabilities (Mage=26.82, SD = 8.42), and a majority of participants were female (69.5%) and Hispanic (85%). Results: No demographic differences were observed in vaccine hesitancy scores in this sample. Those who do not know where to get reliable information about COVID-19 vaccination had higher scores on vaccine hesitancy than those who know how to obtain reliable information; and participants who had a negative experience with a previous vaccination also had higher scores of vaccine hesitancy. Additionally, findings demonstrated COVID-19 vaccine hesitancy scores were negatively associated with openness to experience personality trait and COVID-19-related perceived stress. Conclusions: Implications provide additional insight into factors associated with vaccine hesitancy among college students with disabilities.

Racial Differences in Associations of Cognitive Health Status With Happiness, Helplessness, and Hopelessness Among Older Adults: An Exploratory Study

Background

The relationship between healthy and positive aging and dementia and cognitive impairment has received limited attention in the field of aging. Affect impacts cognitive changes and processes, and cognitive impairment is associated with affective comorbidities. The purpose of the study was to examine (a) whether happiness, helplessness, and hopelessness are linked to cognitive health status, and (b) whether these associations differ by race.

Methods

Participants were enrollees in the Wisconsin Alzheimer's Disease Research Center's Clinical Core (ADRC). Average age at baseline was 60.85 (SD = 8.65), 73.70 (SD = 8.02), and 73.80 (SD = 9.59) years for cognitively normal individuals, individuals with MCI, and individuals with dementia, respectively.

Results

In the full sample, chi-square test results revealed associations between Cognitive Health Status (CHS) and (a) happiness, χ2(2) = 6.06, p < 0.05, (b) helplessness, χ2(2) = 6.44, p < 0.05, and (c) hopelessness, χ2(2) = 14.11, p < 0.01.

Conclusion

This study provides support for the association of both positive and negative affect with cognitive health status in middle- to older-aged adults.

P-FLUX: A phosphorus budget dataset spanning diverse agricultural production systems in the United States and Canada

Quantifying spatial and temporal fluxes of phosphorus (P) within and among agricultural production systems is critical for sustaining agricultural production while minimizing environmental impacts. To better understand P fluxes in agricultural landscapes, P-FLUX, a detailed and harmonized dataset of P inputs, outputs, and budgets, as well as estimated uncertainties for each P flux and budget, was developed. Data were collected from 24 research sites and 61 production systems through the Long-term Agroecosystem Research (LTAR) network and partner organizations spanning 22 U.S. states and 2 Canadian provinces. The objectives of this paper are to (a) present and provide a description of the P-FLUX dataset, (b) provide summary analyses of the agricultural production systems included in the dataset and the variability in P inputs and outputs across systems, and (c) provide details for accessing the dataset, dataset limitations, and an example of future use. P-FLUX includes information on select site characteristics (area, soil series), crop rotation, P inputs (P application rate, source, timing, placement, P in irrigation water, atmospheric deposition), P outputs (crop removal, hydrologic losses), P budgets (agronomic budget, overall budget), uncertainties associated with each flux and budget, and data sources. Phosphorus fluxes and budgets vary across agricultural production systems and are useful resources to improve P use efficiency and develop management strategies to mitigate environmental impacts of agricultural systems. P-FLUX is available for download through the USDA Ag Data Commons (https://doi.org/10.15482/USDA.ADC/1523365).

The Development and Psychometric Validation of the Brief Disability-Related Stress Scale in Individuals With Multiple Sclerosis

Disability-related stress is the unique stressful experiences and challenges people with disabilities encounter. The goal of the study was to develop and validate the Brief Disability-Related Stress Scale ( BDRSS) in a sample of people with multiple sclerosis (MS). Findings demonstrated that the BDRSS is unidimensional and has good psychometric properties (internal consistency reliability coefficient [Cronbach’s α = .86]). The BDRSS was also found to correlate with the Perceived Stress Scale–10 ( PSS-10; r = .69). Results of this study suggested the potential clinical utility of incorporating the BDRSS in rehabilitation, mental health, and neuropsychology settings to assess stressors experienced by people with MS.

The Intermediary Role of Optimism and Mental Health in the Relationship Between Disability-Related Stress and Life Satisfaction: A Serial Mediation Model

Although research has examined the relationship between stress and life satisfaction for individuals with multiple sclerosis (MS), less is known about the mechanism through which disability-related stress affects life satisfaction. The purpose of the study was to examine the intermediary role of optimism and mental health in the relationship between disability-related stress and life satisfaction in people with MS. In this cross-sectional study, the sample consisted of 373 adults with MS (mean age = 47.77 years; SD = 11.70). Descriptive statistics, correlation analyses, and a serial mediation analysis were conducted in this study. Our findings suggested that disability-related stress was inversely associated with optimism, mental health, and life satisfaction. Optimism was positively associated with mental health and life satisfaction. Mental health was positively associated with life satisfaction. The serial mediation analysis results suggested that disability-related stress was negatively associated with life satisfaction through optimism and mental health. Our findings provided implications for clinicians to facilitate optimism and mental health promotion for people with MS.

Character Strengths Across Disabilities: An International Exploratory Study and Implications for Positive Psychiatry and Psychology

The purpose of this study was to examine the differences in character strengths for people with disabilities by using an international dataset by the VIA Institiute on Character. Specifically, we aimed to explore (a) the top and bottom five character strengths reported by different disability groups and all people with disabilities more broadly, and (b) group differences in each character strength and total character strengths. The investigator contacted the VIA Institute on Character (http://www.viacharacter.org/) for obtaining the dataset for the current study. After data cleaning, our sample size resulted in 11,699 people with disabilities. Among most people with disabilities, the top five character strengths scores were love of learning, honesty, appreciation of beauty and excellence, kindness, and fairness. The bottom five character strengths scores were self-regulation, perseverance, zest, spirituality, and prudence. Knowing that there is heterogeneity in character strengths across groups gives us a better understanding of the areas that people with different disabilities and conditions might thrive and provides clinicians and practitioners with a more nuanced understanding for how to possibly intervene with their clients. Positive psychiatry and psychology implications are discussed.

Is Gratitude Associated With Suicidal Ideation in Veterans With Mental Illness and Student Veterans With PTSD Symptoms?

ABSTRACT

The present study is aimed to identify the effect of gratitude as an adaptive regulating mechanism from suicidal ideation (SI) for veterans with mental illness (study 1) and student veterans with posttraumatic stress disorder (PTSD) symptoms (study 2) in the United States. Descriptive statistics and regression analyses were used to examine sociodemographic characteristics and relationships between gratitude and SI. Our study 1 consisted of 156 veterans with mental illness. The mean age for study 1 was 37.85. Our study 2 consisted of 232 student veterans with PTSD symptoms. The mean age for study 2 was 28.43. Higher gratitude scores in study 1 and study 2 were significantly associated with lower SI scores after adjusting for demographics and depression. This study partially supports the association between gratitude and SI in veterans with mental illness. Based on the results from this study, gratitude interventions may be effective in reducing SI when working with veterans with mental illness.

Psychometric Validation of the Wisconsin Community Participation Scale in a Sample of People with Chronic Health Conditions and Disabilities Living in the Community

Increasing community participation can reduce the risk for functional disabilities; participation is influenced by person and environment contextual factors. Development and validation of a brief community participation assessment can advance and support evidence-based assessment in clinical rehabilitation counseling practice. It will be an invaluable rehabilitation and public health surveillance tool that can be used to gauge the health conditions and participation of people with disabilities. The current study evaluated and validated the Wisconsin Community Participation Scale (WCPS) in 982 individuals with chronic health conditions and disabilities. Participants indicated five most meaningful life roles: (a) being able to get around with or without help, (b) live independently with or without help, (c) live a healthy lifestyle, (d) work, and (e) leisure and recreation activities. The WCPS scores were positively associated with physical health, mental health, and life satisfaction and negatively related to functional disability in the theoretically expected directions. The WCPS can help rehabilitation counselors assess their clients’ current level of participation in meaningful life roles that are important to them. Rehabilitation counselors can use the WCPS assessment data to guide treatment planning and empower clients to build confidence and self-efficacy to participate in personally meaningful activities in the community.

Initial experience of TAS-102 chemotherapy in Australian patients with Chemo-refractory metastatic colorectal cancer

For patients with refractory metastatic colorectal cancer (mCRC) treatment with Trifluridine/Tipiracil, also known as TAS-102, improves overall survival. This study aims to investigate the efficacy and safety of TAS-102 in a real-world population from Victoria, Australia. A retrospective analysis of prospectively collected data from the Treatment of Recurrent and Advanced Colorectal Cancer (TRACC) registry was undertaken. The characteristics and outcomes of patients receiving TAS-102 were assessed and compared to those enrolled in the registration study (RECOURSE). Across 13 sites, 107 patients were treated with TAS-102. The median age was 60 years (range: 31-83), compared to 63 for RECOURSE. Comparing registry TAS-102-treated and RECOURSE patients, 75% vs 100% were ECOG performance status 0-1, 74% vs 79% had initiated treatment more than 18 months from diagnosis of metastatic disease and 36% vs 49% were RAS wild-type. Median time on treatment was 10.4 weeks (range: 1.7-32). Median progression-free survival (PFS) was 3.3 months compared to 2 months in RECOURSE, while median overall survival was the same at 7.1 months. Two patients (2.3%) had febrile neutropenia and there were no treatment-related deaths, where TAS-102 dose at treatment initiation was at clinician discretion.TRACC registry patients treated with TAS-102 were younger than those from the RECOURSE trial, with similar overall survival observed. Less strict application of RECIST criteria and less frequent imaging may have contributed to an apparently longer PFS.

A National Study to Assess Validity and Psychometrics of the Short Kessler Psychological Distress Scale (K6)

This study aimed to test the validity and reliability of the Kessler Psychological Distress Scale-6 (K6) with a nationally representative clinical sample with various mental health disorders. The cross-sectional, nationally representative, and publicly available data were extracted from the 2014 Health Center Patient Survey (HCPS), which was sponsored by the Health Resources and Services Administration (HRSA). After excluding certain individuals for the purpose of this study, we had a total of 1,863 participants. The highest and lowest psychological distress weighted scores were reported by individuals with bipolar disorder ( M = 17.16) and individuals with schizophrenia ( M = 16.09), respectively, although psychological distress interference was highest in individuals with schizophrenia ( M = 2.44). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) results yielded a unidimensional factor solution for K6 scale in all subgroups. The K6 is a brief, reliable, and valid measure of psychological distress in adults with panic disorder, generalized anxiety disorder, bipolar disorder, and schizophrenia.

Alterations of a serum marker of collagen X in growing children with osteogenesis imperfecta

Abnormalities in the structure and/or processing of type I collagen cause osteogenesis imperfecta and result in bone fragility, abnormal bone growth and short stature. Type I collagen is expressed in the growth plate but the mechanisms by which abnormalities in collagen I contribute to growth plate dysfunction and growth retardation are unknown. The non-collagenous domain (NC1) of type X collagen (CXM) is released from the hypertrophic zone of active growth plates and is a marker for new endochondral bone formation. Serum CXM levels are strongly correlated with the rate of growth in healthy children. We hypothesized that CXM levels in children with OI would be abnormal when compared to normally growing children. Using participants from the Brittle Bone Disease Consortium Natural History Study we analyzed the distribution of CXM over the ages of 8 months to 40 years in 187 subjects with OI (89 type I and 98 types III/IV) as well as analyzed the relationship between growth velocity and CXM levels in a subset of 100 children <16 years old with OI (44 type I and 56 types III/IV). CXM levels in both control and OI children demonstrated a similar pattern of variation by age with higher levels in early life and puberty followed by a post-pubertal drop. However, there was greater variability within the OI cohort and the relationship with growth velocity was weaker. The ratio of CXM level to growth velocity was elevated in children with type III/IV OI compared to controls. These results suggest that the relationship between hypertrophic zone function and the end point of skeletal growth is disrupted in OI.

Exploration of the Effects of Protective Person–Environment Factors Between Functional Impairments and Stress in Individuals With Multiple Sclerosis: Mediation and Moderation Analyses

Functional impairments can lead to stress in individuals with multiple sclerosis (MS). The study examined protective person and environment factors (i.e., positive cognitive stress appraisal, core self-evaluations [CSE], resilience, hope, spirituality, social support, and environmental supports) as both mediators and moderators of this association to guide understanding of the experience of stress in this population. The sample consisted of 373 participants with MS. In simple mediation analyses, positive cognitive stress appraisal, CSE, resilience, hope, social support, and environmental supports served as a partial mediator between functional impairments and stress. In a parallel mediation analysis, significant unique indirect effects were observed for two of the seven hypothesized mediator variables (CSE and environmental supports). Separate moderator tests provided support for the CSE variable as a protective factor. The positive association between functional impairments and stress was weaker for persons reporting high CSE compared with those reporting low CSE. The findings provide implications for rehabilitation counseling practices by promoting CSE and environmental supports in improving rehabilitation and psychosocial outcomes for individuals with MS.
