Neuro-QOL: brief measures of health-related quality of life for clinical research in neurology

Relationship between social support, functional outcomes and health-related quality of life in working-aged adults at three months after ischemic stroke: results from the FRAILTY study

BACKGROUND

The relationship between social support and functional outcomes and health-related quality of life (HRQoL) after ischemic stroke (IS) remains unclear, especially in working-aged patients.

AIM

To assess the relationship between perceived social support, functional outcomes, post-stroke psychosocial symptoms, and HRQoL in working-aged adults three months after IS.

METHODS

A prospective and correlational design was used. Patients of working age (18-65 years) admitted for first-ever IS were enrolled in the prospective FRAILTY (Factors Affecting the Quality of Life After Ischemic Stroke in Young Adults) study (NCT04839887). HRQoL (using the Stroke Impact Scale, Quality of Life in Neurological Disorders), social support (using the Multidimensional Scale of Perceived Social Support), functional outcomes (using a modified Rankin Scale-mRS), and post-stroke psychosocial symptoms were assessed three months after IS. Descriptive statistics, Wilcoxon signed-rank test, Spearman's correlations and multiple linear regression were used for analysis.

RESULTS

A total of 121 (54.5% males, mean age 51.7 ± 8.4 years) IS patients were analyzed. Of those, 87.7% had excellent clinical outcomes (mRS 0-1) after three months. Patients reported significant improvement in all domains of self-reported HRQoL except memory and communication after three months. The overall perceived social support was not associated with HRQoL domains. Post-stroke depression was negatively associated with all domains of HRQoL. Living arrangements (living alone) and post-stroke depression were negatively associated with perceived social support after IS.

CONCLUSIONS

More insight into the relationship between variables of HRQoL in working-aged adults might increase their social participation, strengthen supportive relationships, and promote their recovery and rehabilitation process. Focusing on the management of emotional problems and supporting functional outcomes may be modifiable factors that may represent targets for strategies to improve the HRQoL. Further research is needed to clarify the relationship between pre-stroke perceived social support and its types and post-stroke psychosocial symptoms in the long term.

Sleep health of adults and children with Moebius syndrome

INTRODUCTION

Moebius syndrome is a rare congenital disorder with frequent anecdotal reports of sleep disturbances not sufficiently categorized by prior literature. The present mixed-methods, two-phase study aimed to characterize the sleep health and symptoms of a cohort of adults and children (via parent proxies) with Moebius syndrome.

METHODS

In Phase 1, participants were 46 adults with Moebius Syndrome (Mage=33.5[13.0]; 72 % female) and 17 parent-proxies for children with Moebius Syndrome (child Mage=10.47[3.4]; 53 % female). Participants completed a self-reported questionnaire battery. In Phase 2, five adults (Mage=25.4[6.5]; 100 % female) from Phase 1 completed 2 weeks of sleep diary and actigraphy, 2 nights of single-channel EEG, and diagnostic and qualitative interviews.

RESULTS

Adults endorsed elevated rates of self-reported sleep disorder symptoms including sleep apnea (26 %), insomnia (56 %), nightmares (35 %), excessive daytime sleepiness (30 %), cataplexy (26 %), REM sleep behavior disorder (61 %), and parasomnias (100 %). Children had elevated rates of sleep disturbances (71 %), sleep-related daytime impairment (82 %), parasomnias (76 %) and daytime sleepiness (53 %). Qualitative interviews revealed participants endorsed a history of sleep problems dating to childhood and continuing into adulthood that impacted social relationships and quality of life and had experienced little treatment success.

DISCUSSION

These findings shed light on the constellation of sleep health experiences among individuals with Moebius syndrome. Poor sleep health may represent a modifiable treatment target to improve health and well-being in individuals with Moebius syndrome. The heterogenous nature of sleep problems among people with Moebius syndrome may not respond well to a one-size-fits-all intervention, instead necessitating personalized approaches.

Real world effectiveness, persistence, tolerability, and safety of ofatumumab in clinical practice

AIMS

To describe the 12-month effectiveness, persistence, tolerability, and safety of ofatumumab (OMB), a highly effective disease-modifying therapy (DMT) for relapsing multiple sclerosis (MS), in a real-world MS population.

PATIENTS & METHODS

Electronic medical records of patients starting OMB from October 2020 to August 2022 at two comprehensive MS centers were reviewed. Demographics and disease characteristics and 6- and 12-month clinical, patient-reported, and radiologic outcome measures were analyzed.

RESULTS

A total of 175 patients started OMB with mean age 44.9 (SD 10.4) and disease duration 13.6 (SD 9.6) years. The cohort was 74% female, included 81% White and 13% Black American patients, and consisted of 80% relapsing-remitting MS or clinically isolated syndrome. Most (87%) had prior DMT exposure with 38% switching from high efficacy DMT. Over 12 months, 9.7% discontinued OMB (mean 117 days, SD 99.2), with tolerability issues being the most common reason. Thirty-nine (22%) had relapses in the year before starting OMB. By 12 months, only 1 relapse had occurred after approximately 4 months post-treatment initiation.

DISCUSSION

This real-world study demonstrated that OMB is highly effective with robust persistence and good safety and tolerability by 12-month follow-up. Further analyses are planned to examine longer-term outcomes.

Building consensus on clinical outcome assessments for BCI devices. A summary of the 10th BCI society meeting 2023 workshop

Objective: The 10th International brain computer interface (BCI) Society Meeting, 'Balancing Innovation and Translation', was held from the 6th to 9th of June 2023 in Brussels, Belgium. This report provides a summary of the workshop 'Building Consensus on Clinical Outcome Assessments (COAs) for BCI Devices'. This workshop was intended to give participants an overview of the current state of BCI, future opportunities, and how different countries and regions provide regulatory oversight to support the BCI community to develop safe and effective devices for patients.Approach: Five presentations and a panel discussion including representatives from regulators, industry, and clinical research stakeholders focused on how various stakeholders and the BCI community might best work together to ensure studies provide data that is useful for evaluating safety and effectiveness, including reaching consensus on COAs that represent clinically meaningful benefits and support regulatory and payor requirements. This report focuses on the regulatory and reimbursement requirements for medical devices and how to best measure safety and effectiveness and summarizes the presentations from five experts and the discussion between the panel and the audience.Main results: Consensus was reached on the following items specifically related to BCI: (i) the importance of and need for a new generation of COAs, (ii) the challenges facing the development of appropriate clinical outcome assessments, and (iii) that improvements in COAs should demonstrate obvious and clinically meaningful benefit(s). There was discussion on: (i) clinical trial design for BCIs and (ii) considerations for payor reimbursement and other funding.Significance: Whilst the importance of building community consensus on COAs was apparent, further collaboration will be required to reach consensus on which specific current and/or novel COAs could be used for the BCI field to evolve from research to market.

A Comparison of In-Person and Telehealth Treatment Modalities using the SpeechVive Device

Telehealth is increasing popular as a treatment option for people with Parkinson disease (PD). The SpeechVive device is a wearable device that uses the Lombard effect to help patients speak more loudly, slowly, and clearly. This study sought to examine the effectiveness of the device to improve communication in people with PD, delivered over a telehealth modality as compared to in-person, using implementation science design. 66 people with PD were enrolled for 12 weeks with 34 choosing the in-person group and 32 in the telehealth group. Participants were assessed pre-, mid-, and post-treatment. Participants produced continuous speech samples on and off the device at each timepoint. Sound pressure level (SPL), utterance length, pause frequency, and total pause duration were measured. Psychosocial surveys were administered to evaluate the effects of treatment on depression, self-efficacy, and participation. The in-person group increased SPL when wearing the device while the telehealth group did not. Both groups paused less often while wearing the device. Utterance length increased post-treatment for the telehealth group, but not for the in-person group. An increase in communication participation ratings in the telehealth group, but not the in-person group, was the only significant change in the psychosocial metrics. The in-person group showed similar treatment effects as previous studies. The device was not as effective in the telehealth group. One limitation was data loss due to recording issues that impacted the telehealth group more than the in-person group.

Eye Tracking during Passage Reading Supports Precise Oculomotor Assessment in Ataxias

Abnormal eye movements occur early in the course of disease in many ataxias. However, clinical assessments of oculomotor function lack precision, limiting sensitivity for measuring progression and the ability to detect subtle early signs. Quantitative assessment of eye movements during everyday behaviors such as reading has potential to overcome these limitations and produce functionally relevant measures. In this study, we analyze eye movements in individuals with ataxia during passage reading. Binocular gaze sampled at 1000 Hz was collected from 102 individuals with ataxia diagnoses (including 36 spinocerebellar ataxias, 12 Friedreich's ataxia, and 5 multiple system atrophy among other conditions) and 70 healthy controls participating in the Neurobooth study. Longitudinal data were available for 26 participants with ataxia. Saccades were categorized as progressive (rightward) saccades, regressive saccades, or sweeps (large displacement saccades primarily generated when scanning to the beginning of the next line) based on their direction and displacement. Saccade and fixation kinematics were summarized using 28 statistical features. A linear model was trained to estimate clinician-performed ataxia rating scale scores. Model scores were reliable (ICC=0.96, p<0.001) and demonstrated convergent validity with Brief Ataxia Rating Scale total (r=0.82, p<0.001), oculomotor (r=0.52, p<0.001), and speech (r=0.73, p<0.001) scores, as well as patient surveys. The scores were also sensitive to disease progression (d=0.36, p=0.03), demonstrated strong separability between healthy controls and participants with ataxias (AUC=0.89, p<0.001), and showed evidence of the ability to detect subclinical oculomotor patterns (AUC=0.69, p=0.02). Several kinematic saccade and fixation features demonstrated strong differences across disease severity groups. Notable features included the mean angular displacement of fixations ( η 2 =0.44, p<0.001), the number ( η 2 =0.27, p<0.001) and frequency of saccades ( η 2 =0.25, p<0.001), and the proportion of regressive saccades ( η 2 =0.11, p<0.001). Quantitative assessment of eye movements during passage reading were highly informative of ataxia severity, were sensitive to disease progression, and enabled detection of subclinical signs. These properties support the inclusion of video-oculography-based measures of reading in natural history studies and clinical trials. Furthermore, this study demonstrates the feasibility of integration of oculomotor assessments in clinical workflows.

Multi-domain Online Therapeutic Investigation Of Neurocognition (MOTION) - A randomized comparative-effectiveness study of two remotely delivered mind-body interventions for older adults with cognitive decline

BACKGROUND

Research suggest that mind-body movement programs have beneficial effects on cognitive outcomes for older adults with cognitive decline. However, few studies have directly compared specific approaches to mind-body movement or studied the impact of remote program delivery.

METHODS

In a 3-arm randomized controlled trial (RCT) for older adults with cognitive impairment, we are comparing a multidomain mind-body program that emphasizes movement, body awareness, personal meaningfulness, and social connection, and a traditional Chinese mind-body exercise (Tai Chi) to a health and wellness education control condition. All 3 interventions are delivered remotely two times per week (onehour per session) for 12 weeks. The two active interventions are live-streamed. Outcomes are assessed prior to, after, and 6-months after the interventions. The co-primary outcomes are changes on the Alzheimer's Disease Assessment Scale - Cognitive Subscale (ADAS-cog) and brain functional connectivity in the Default Mode Network (DMN). Secondary outcomes include measures of specific cognitive domains (e.g., executive function, attention), mobility, and self-report measures of general well-being, quality of life, social engagement, self- and attention-regulation.

CONCLUSION

This RCT will directly compare the effects of two mind-body movement programs versus an education control delivered remotely over 12 weeks on cognitive, neuroimaging, and participant-reported outcomes. If successful, these programs may provide scalable strategies for slowing cognitive decline, which could potentially delay dementia onset in some individuals.

Focused Ultrasound Neuromodulation: Exploring a Novel Treatment for Severe Opioid Use Disorder

BACKGROUND

Opioid use disorder remains a critical healthcare challenge as current therapeutic strategies have limitations resulting in high recurrence and deaths. We evaluated safety and feasibility of focused ultrasound (FUS) neuromodulation to reduce substance cravings and use in severe opioid- and co-occurring substance use disorders.

METHODS

This prospective, open-label, single-arm study enrolled 8 participants with severe, primary opioid use disorder with co-occurring substance use. Participants received a 20-minute session of low-intensity FUS (220 kHz) neuromodulation targeting the bilateral nucleus accumbens (NAc) with follow-up for 90-days. Outcome measures included safety, tolerability, feasibility, and effects of FUS neuromodulation by assessment of adverse events, substance craving, substance use (self-report, urine toxicology), mood, neurologic examinations, and anatomic and functional MRI, at 1-, 7-, 30-, 60, and 90- day post-FUS.

RESULTS

No serious device-related adverse events or imaging abnormalities were observed. Following FUS, participants demonstrated immediate (p<.002) and sustained (p<.0001; mean 91%) reduction in cue-induced opioid craving with median rating on scale from 0-10: 6.9 (pre-FUS) vs. 0.6 (90-day post-FUS). Craving reductions were similar for other illicit substances (e.g., methamphetamine (p<.002), cocaine (p<.02)). Decreases in opioid and co-occurring substance use were confirmed by urine toxicology. Seven participants remained abstinent at 30-days; 5 remained abstinent throughout 90-days post-FUS. Resting-state functional MRI demonstrated decrease in connectivity from the NAc to reward and cognitive regions post-FUS.

CONCLUSIONS

NAc FUS neuromodulation is safe and a potential adjunctive treatment for reducing drug cravings and use in individuals with severe opioid- and co-occurring substance use disorders. Larger, sham-controlled, randomized studies are warranted.

Comparative Effectiveness of In-Person and Virtual Picture-Naming Treatment for Poststroke Anomia

PURPOSE

In light of COVID-19, telepractice for speech therapy has been increasingly adopted. Telepractice promotes accessibility to therapy services for those in rural environments, lowers the frequency of missed appointments, and reduces the costs of rehabilitation. The efficacy of telepractice has been scarcely explored in the aphasia literature. Preliminary research has demonstrated comparable results of telepractice and in-person therapy for people with aphasia, but the current scope of research is insufficient to guide clinical practice. The present study examined whether the virtual administration of a picture-naming therapy paradigm was as effective as in-person administration.

METHOD

The treatment effects of two similar clinical trials, one completed in-person (n = 13) and one completed virtually (n = 13), are compared. Participants were adults with chronic (> 6 months) poststroke aphasia. Both clinical trials administered Cued Picture-Naming Therapy 4 days a week for 2 weeks (eight treatment sessions). Treatment outcomes were analyzed using Tau-U effect sizes and Mann-Whitney U tests.

RESULTS

Weighted Tau-U averages showed an advantage of telepractice over in-person treatment in the acquisition effects of trained words, with participants demonstrating a very large effect (0.84, p < .01) following telepractice and a large effect (0.75, p < .01) following in-person treatment. Both telepractice and in-person rehabilitation demonstrated significant treatment effects and were not significantly different from each other per Mann-Whitney U independent-samples t tests.

CONCLUSIONS

The present study demonstrated that telepractice of a picture-naming paradigm is as effective as in-person treatment administration. This justifies the use of telepractice to overcome accessibility and cost barriers to speech therapy administration and justifies taking patient preference into account. Future research should explore the efficacy of telepractice for treatments that promote greater generalizability to functional communication.

Management of Velopharyngeal Impairment in Adults With Dysarthria: A Systematic Review

PURPOSE

Velopharyngeal impairment (VPI) is a common manifestation of dysarthria, yet there is uncertainty regarding the evidence for treatment options. The aim of this systematic review was to identify and evaluate published intervention studies of VPI and to update the original Practice Guidelines for VPI, as part of the Dysarthria Writing Group of the Evidence-Based Clinical Research Committee of the Academy of Neurologic Communication Disorders and Sciences.

METHOD

Four electronic databases were searched for articles published through September 2022 in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses standards. Multiple indices of methodological quality and risk of bias were used to evaluate studies.

RESULTS

The search yielded 1,347 articles, of which 31 met inclusion criteria and were reviewed by two blinded co-investigators and a third consensus reviewer. Therapeutic approaches centered on prosthetic treatment (n = 13), prosthetic treatment combined with another form of therapy (n = 7), and behavioral exercise (n = 7), with four additional studies reporting unconventional approaches (e.g., use of medication). No single treatment approach garnered strong evidence. However, converging moderate evidence suggests positive treatment outcomes for prosthetic approaches for moderate-severe speakers with flaccid/spastic dysarthria and behavioral treatment approaches for speakers spanning a range of nonprogressive dysarthrias.

CONCLUSIONS

There is a critical need for well-controlled treatment studies of VPI that incorporate comprehensive and systematic description of baseline speech function, treatment protocols, and operationally defined outcome measures, particularly related to social validity and participation goals. Suggestions for how clinicians can apply extant research findings to practice are provided.

Optimizing rare disorder trials: a phase 1a/1b randomized study of KL1333 in adults with mitochondrial disease

Over the past two decades there has been increased interest in orphan drug development for rare diseases. However, hurdles to clinical trial design for these disorders remain. This phase 1a/1b study addressed several challenges, while evaluating the safety and tolerability of the novel oral molecule KL1333 in healthy volunteers and subjects with primary mitochondrial disease. KL1333 aims to normalize the NAD+:NADH ratio that is critical for ATP production. The trial incorporated innovative design elements with potential translatability to other rare diseases including patient involvement, adaptive design and exploratory objectives, all of which have subsequently informed the protocol of an ongoing phase 2, pivotal efficacy study of KL1333. Results indicate KL1333 is safe and well tolerated, with dose-dependent gastrointestinal side effects, and validate potential novel outcome measures in primary mitochondrial disease including the 30-s Sit to Stand, and the patient-reported fatigue scales. Importantly, the data from the trial support efficacy of KL1333 based on improvements in fatigue and functional strength and endurance. Furthermore, the study highlights the value in using phase 1 studies to capture data that helps optimize later phase efficacy trial design.

Changes in Subjective Cognitive and Social Functioning in Parkinson's Disease from Before to During the COVID-19 Pandemic

Background/Objectives: Social isolation and health-related consequences of the COVID-19 pandemic may have significantly impacted quality of life in people with Parkinson's disease (PwPD). The effect of the COVID-19 pandemic specifically on subjective cognition and social functioning in PwPD is poorly understood. We conducted a longitudinal analysis of changes in subjective cognitive and social functioning in PwPD before (T1, 2017-2019) and during (T2, 2021) the COVID-19 pandemic. Methods: At T1, 347 PwPD completed online surveys. At T2, 123 of them (54 males, 69 females) responded to follow-up questionnaires including Quality of Life in Neurological Disorders (Neuro-QoL) subscales, Beck Depression Inventory-II, Parkinson's Anxiety Scale, motor and non-motor experiences of daily living from the MDS-Unified Parkinson's Disease Rating Scale, and the Coronavirus Impact Scale. Results: T1-T2 declines in subjective cognition and social functioning both were correlated with more anxiety, fatigue, and motor symptoms. Additionally, declines in subjective cognition correlated with depression, and with decline in social functioning. Women reported greater COVID-19 impact than men, unrelated to cognition and social functioning; in men, personal experience with COVID-19 was associated with decline in subjective cognition. Conclusions: Our finding that subjective cognition and social functioning are associated with different motor and non-motor symptoms of PD suggests that the impacts of PD on subjective cognition and social functioning are complex, which has important implications for treatment.

Beyond the Nest: The Role of Financial Independence in Young Adult Health

BACKGROUND

This study aimed to examine the impact of neighborhood conditions and household material hardship experiences on young adult health outcomes, while also considering financial autonomy as a critical determinant of health.

METHOD

We employed a cross-sectional observational design with a diverse sample of young adults from a large urban university. Structural equation modeling was used to analyze the relationships between neighborhood conditions and material hardship with health outcomes by financial autonomy.

RESULTS

Material hardship and neighborhood conditions were significantly related to various health outcomes among young adults. Food insecurity emerged as a significant mediator linking neighborhood conditions to health including global physical health, cognitive functioning, and depression. Financially independent young adults showed stronger direct and indirect effects of neighborhood conditions on health compared to financially dependent counterparts.

CONCLUSION

This study underscores the complex interplay of neighborhood conditions, household material hardship, and financial autonomy in shaping young adult health. Our findings also suggest how the impact of SDOH on young adult health may have long-term effects later in life. Future research should consider these factors comprehensively to address disparities in emerging adult health.

Impact of Upper Limb Function on Activities of Daily Living and Quality of Life in Huntington's Disease

Background/Objectives: Huntington's disease (HD) is a neurodegenerative movement disorder associated with significant disability and impairment of Activities of Daily Living (ADLs). The impact of upper limb disability on quality of life (QoL) and its influence on ADLs is not well known yet. The aim of this study was to describe the manipulative dexterity, strength, and manual eye coordination of patients with manifest and premanifest-HD compared to healthy individuals and to analyze its influence on ADLs and QoL. Methods: We performed an observational, cross-sectional study including 71 ambulatory participants (27 manifest-HD patients, 15 premanifest-HD, and 29 controls). We gathered sociodemographic data, as well as clinical data, including cognition (MMSE), HD motor severity (Unified HD rating scale, UHDRS-TMS), QoL (Neuro-QoL), and ADLs (HD-ADL). Hand dexterity and strength in the dominant and non-dominant hand were assessed with the Nine Hole Peg Test, Ten Neurotest, Nut and Bolt Test, dynamometry, and Late-Life FDI. Analysis of covariance (ANCOVA) models were performed to investigate differences in hand function between manifest-HD, premanifest-HD, and controls. Results: Manifest-HD patients had significantly worse performance in manual and finger dexterity, fine-motor coordination, and poorer handgrip strength than premanifest-HD and controls. Premanifest-HD required more time to complete the test than controls. Significant correlations were found between hand variables and Late-Life FDI, Neuro-QoL, HD-ADL, and UHDRS-TMS. Conclusions: HD affects manipulative dexterity and hand function in premanifest and manifest patients. Therefore, to prevent disability and decreased QoL, evaluating the progression of upper limb dysfunction in HD is important to offer the best possible therapeutic interventions.

Effects of Situational Loneliness on Mental Health and Sleep Health Outcomes among White Older Adults during the COVID-19 Pandemic

OBJECTIVES

This study examined the cross-sectional and 2-year prospective associations between situational loneliness and health outcomes in older adults during the COVID-19 pandemic.

METHODS

Data were collected using an online survey that evaluated behaviors (e.g., socialization) and health outcomes at two points (May-June 2020 and October-November 2022) during the pandemic. Logistic regression was used to analyze the cross-sectional associations between situational loneliness and health outcomes (i.e., depressive symptoms, anxiety symptoms, and sleep health) while linear regression was used to examine the prospective associations.

RESULTS

In a sample of 428 older adults (age 65 +), situational loneliness was associated with short-term, but not long-term, increases in depressive symptoms, anxiety symptoms, and problems with sleep.

CONCLUSION

Findings suggest that the older adult population demonstrates resilience in the face of short-term increases in loneliness. Thus, promoting resilience may be a promising strategy for mitigating the negative consequences of situational loneliness.

SPOON: an observational, cross-sectional study of perceptions and expectations of adults with generalised myasthenia gravis in France

OBJECTIVES

To capture patient perceptions about living with myasthenia gravis (MG) with respect to aspirations and ways to improve treatment.

DESIGN

Online patient survey.

SETTING

Patients recruited by MG patient associations or at MG reference treatment centres.

PARTICIPANTS

Adults with physician-diagnosed generalised MG, living in France for ≥12 months, who had received ≥1 MG treatment were eligible. 291 patients opened the questionnaire, 255 were eligible and 246 completed the survey (age range 41-67 years; 187 women and 59 men).

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary: free-text response to the question 'Living with your disease, what would you like to do that you currently find difficult or impossible to do?' Secondary: free-text response to the question 'What improvements do you think could be made to treatments for MG?' Themes from replies to these questions were analysed using grounded theory and cluster analysis.

RESULTS

For the disease aspirations question, 617 citations were provided by 238 participants, which were grouped into 45 dimensions and six high-level domains (physical activity, activities of daily living, psychological burden, social activities, work/school and other). The most frequently cited dimensions were sport (82 citations), greater mobility (56 citations), being less tired (46 citations) and greater endurance (37 citations). Younger age, female gender, recent diagnosis and poorer quality of life were associated with citing more themes. For the treatment amelioration question, 263 citations were provided by 195 participants, which were grouped into 60 dimensions and three high-level domains (medication characteristics, safety and care paradigm). The most cited treatment-related dimensions were fewer side effects (40 citations), fewer daily medication intakes (21 citations) and fewer digestive side effects (20 citations).

CONCLUSIONS

These findings could help healthcare professionals to understand and better address patients' aspirations about living with MG, notably concerning the importance of physical activity, and their expectations for improved treatments.

A digital intervention for cognitive deficits following COVID-19: a randomized clinical trial

Post-COVID-19 cognitive deficits are common, persistent, and disabling. Evidence on effective treatments is limited. The goal of this study was to investigate the efficacy of a digital intervention to reduce cognitive and functional deficits in adults with persistent post-COVID-19 cognitive dysfunction. We used the remotely-delivered intervention in a randomized clinical trial conducted from July 13, 2021 to April 26, 2023. We hypothesized that participants in the intervention group would improve in measures of cognition and daily functioning. Participants were adults with cognitive deficits persisting >4 weeks following acute COVID-19 illness. Of 183 participants screened, 110 were enrolled; 98 participants (78.6% female; mean age = 48.1) completed at least one study visit. Participants were randomized 1:1 to the intervention (AKL-T01) or waitlist control. AKL-T01 is a digital therapeutic using a videogame interface to target attention and executive control. The intervention was delivered remotely for 6 weeks. The primary outcome was change in performance on a sustained attention measure (Digit Symbol Matching Task). The difference in the primary outcome between the intervention (n = 49) and controls (n = 49) was not statistically significant (F [3,261] = 0.12, p = 0.95). Secondary cognitive outcomes of task-switching (F[3,262] = 2.78, p = 0.04) and processing speed (F[3,267] = 4.57, p = 0.004) improved in the intervention relative to control. Secondary measures of functioning also improved in the intervention relative to control, including disability (F[1,82] = 4.02, p = 0.05) and quality of life (F[3,271] = 2.66, p = 0.05). Exploratory analyses showed a greater reduction in total fatigue (F[1,85] = 4.51, p = 0.04), cognitive fatigue (F[1,85] = 7.20, p = 0.009), and anxiety (F[1,87] = 7.42, p = 0.008) in the intervention relative to control. Despite the lack of improvement in sustained attention, select post-COVID-19 cognitive deficits may be ameliorated by targeted cognitive training with AKL-T01, with associated improvements in quality of life and fatigue. If replicated, the scalable nature of this digital intervention may help address substantial need for accessible, effective treatments among individuals with long COVID.

Sleep fragmentation despite intact rest-activity patterns in premanifest Huntington's disease: An actigraphy study

OBJECTIVE

Sleep research in Huntington's disease (HD) has primarily focused on manifest HD, with significantly less attention given to premanifest HD (Pre-HD). Therefore, we investigated sleep and rest-activity patterns in people with Pre-HD versus healthy controls (HC).

METHODS

We conducted a cross-sectional study including 36 Pre-HD and 48 HC participants. Pre-HD participants were stratified into three groups according to their proximity to estimated diagnosis, using a cytosine-adenine-guanine (CAG) and current age-based predictive model: NEAR (<9 years to diagnosis), MID (9-15 years to diagnosis) and FAR (>15 years to diagnosis). Sleep and rest-activity patterns were assessed using wrist-worn actigraphy, a sleep diary, and sleep questionnaires.

RESULTS

NEAR and MID groups experienced higher fragmentation index than HC and FAR groups. NEAR and MID groups also exhibited greater WASO than the FAR group. NEAR and MID groups showed lower intra-daily variability (IV) than HC and FAR groups, with the NEAR group also being more active in the most active 10 h (M10). Groups did not differ on subjective sleep measures, inter-daily stability (IS), sleep regularity index, relative amplitude, or amount of activity in the least active 5 h (L5). Considering all Pre-HD participants, fewer years to diagnosis, higher CAG-age-product (CAP) scores (a measure of cumulative exposure to the HD-causing gene mutation) and larger CAG repeat lengths correlated with higher WASO, fragmentation index, L5, IS, and lower sleep efficiency and IV. Higher CAP score correlated with higher M10.

CONCLUSIONS

Despite intact rest-activity patterns and similar subjective sleep quality to HC, greater sleep fragmentation is a prominent and early feature in Pre-HD. Therefore, reducing sleep fragmentation may be a potential target for sleep intervention in HD. Longitudinal studies using larger samples are needed to assess sleep across the disease spectrum and its impact on clinical outcomes, like cognition.

Respiratory Strength Training Versus Respiratory Relaxation Training in the Rehabilitation of Physical Impairment, Function, and Return to Participation After Stroke: Protocol for a Randomized Controlled Trial

BACKGROUND

Persistent disability in chronic stroke survivors is often attributed to arm or leg weakness; however, respiratory muscle weakness also impedes poststroke rehabilitation, reduces quality of life, and increases the risk of health complications. Respiratory complications are common after stroke and place patients at risk for both prolonged functional disability and mortality. In addition, stroke survivors face ongoing cardiovascular disease that places them at risk for recurrent stroke.

OBJECTIVE

The study aims to compare the effects of 2 respiratory training programs, paired with individualized flexibility, strengthening, and cardiovascular exercise programs, on physiologic, activity, and societal participation outcomes in chronic stroke survivors.

METHODS

This study will be a randomized controlled trial. Participants are 80 community-dwelling adults with chronic stroke. In conjunction with a 24-session (3 times/week for 8 weeks), American Heart Association-informed, whole-body exercise program, participants will be randomized to receive either respiratory strength training or respiratory relaxation training. Study intervention will be directed by a physical therapist and take place in a community fitness center. Outcome assessments will occur in a clinical research center. The primary outcome measure is maximal respiratory pressure. Secondary outcome measures include airway clearance, walking endurance, spatial-temporal gait characteristics, community walking, functional strength and fatigue, depression, and societal participation measures. Longer-term societal participation is a complex domain that may be influenced by other factors beyond physical function. Participants' health status will be monitored for 1 year following the intervention for falls, respiratory illness, and hospitalizations. Additional subanalyses will evaluate the effect of smoke exposure on short- and long-term outcomes. Outcome assessors are blinded to group assignments. Respiratory relaxation training is an active comparator, but no pure control group is included.

RESULTS

This study was funded in March 2020 with enrollment commencing in November 2020. Completion of enrollment is projected for May 2025 with a study projected end date of April 2026. Published results are anticipated in Fall 2026.

CONCLUSIONS

Results from this study will improve our understanding of the additive benefits of respiratory exercises on short- and long-term physiologic, functional, and societal gains for these individuals. These data will be instructive to meet a current unmet rehabilitative need to promote patient-centered care and contribute to decreasing morbidity and mortality in chronic stroke survivors.

Four New Patient-Reported Outcome Measures Examining Health-Seeking Behavior in Persons With Type 2 Diabetes Mellitus (REDD-CAT): Instrument Development Study

BACKGROUND

The management of type 2 diabetes mellitus (T2DM) includes mastery of complex care activities, self-management skills, and routine health care encounters to optimize glucose control and achieve good health. Given the lifelong course of T2DM, patients are faced with navigating complex medical and disease-specific information. This health-seeking behavior is a driver of health disparities and is associated with hospitalization and readmission. Given that health-seeking behavior is a potentially intervenable social determinant of health, a better understanding of how people navigate these complex systems is warranted.

OBJECTIVE

To address this need, we aimed to develop new patient-reported outcome (PRO) measures that evaluate health-seeking behavior in persons with T2DM. These new PROs were designed to be included in the Re-Engineered Discharge for Diabetes-Computer Adaptive Test (REDD-CAT) measurement system, which includes several other PROs that capture the importance of social determinants of health.

METHODS

Overall, 225 participants with T2DM completed 56 self-report items that examined health-seeking behaviors. Classical Test Theory and Item Response Theory were used for measurement development. Exploratory factor analysis (EFA; criterion ratio of eigenvalue 1 to eigenvalue 2 being >4; variance for eigenvalue 1 ≥40%) and confirmatory factor analysis (CFA; criterion 1-factor CFA loading <.50; 1-factor CFA residual correlation >.20; comparative fit index ≥0.90; Tucker-Lewis index ≥0.90; root mean square error of approximation <0.15) were used to determine unidimensional sets of items. Items with sparse responses, low-adjusted total score correlations, nonmonotonicity, low factor loading, and high residual correlations of high error modification indices were candidates for exclusion. A constrained graded response model was used to examine item misfit, and differential item functioning was examined to identify item bias. Cronbach α was used to examine internal consistency reliability for the new PROs (criterion ≥0.70), and floor and ceiling effects were examined (criterion ≤20%).

RESULTS

Four unidimensional sets of items were supported by EFA (all EFA eigenvalue ratios >4; variance for eigenvalue 1=41.4%-67.3%) and CFA (fit statistics all exceeded criterion values). This included (1) "Health-Seeking Behavior: PCP-Specific" (6 items); (2) "Health-Seeking Behavior: General Beliefs" (13 items); (3) "Health-Seeking Behavior: Family or Friends-Specific" (5 items); and (4) "Health-Seeking Behavior: Internet-Specific" (4 items). All items were devoid of differential item functioning for age, sex, education, or socioeconomic status factors. "Health-Seeking Behavior: General Beliefs" was developed to include both a computer adaptive test and a 6-item short form version; all other PROs were developed as static short forms. The psychometric reliability of these new PROs was supported; internal consistency ranged from acceptable to excellent (Cronbach α=.78-.91), and measures were free of significant floor or ceiling effects (floor effects range: 0%-8.9%; ceiling effects range: 0%-8.4%).

CONCLUSIONS

The new REDD-CAT Health-Seeking Behavior PROs provide reliable assessments of health-seeking behaviors among those with T2DM.

Apathy and Functional Status in Early-Stage Huntington's Disease

OBJECTIVE

Apathy is common in Huntington's disease (HD) and difficult to treat. Multiple recent calls have been made to increase understanding of apathy across the spectrum of HD severity. Functional status is an important outcome in HD trials; however, no consensus currently exists regarding the impact of apathy on functional status in HD. The authors aimed to identify correlates of apathy and effects on functional status in a primarily early-stage HD sample.

METHODS

This study included secondary analyses of data from a study of neuropsychiatric symptoms in a clinical HD sample. Spearman correlation analyses were used to assess the relationships between apathy (with the Frontal Systems Behavior Scale-Apathy [FrSBe-Apathy] subscore), clinical variables, and patient-reported outcomes. To assess the association of apathy with functional status, two multiple regression analyses were performed, with a different functional status measure (Adult Functional Adaptive Behavior [AFAB] scale or Total Functional Capacity [TFC] scale) as the dependent variable in each analysis.

RESULTS

Statistically significant correlates of apathy included the Quality of Life in Neurological Disorders (Neuro-QoL) Satisfaction With Social Roles and Activities and Neuro-QoL Positive Affect and Well-Being scores (N=70 patients). Univariate correlation analyses also revealed statistically significant associations of FrSBe-Apathy scores with both functional status measures. In the multiple regression analyses, apathy significantly contributed to variability in functional status as measured by both the AFAB (N=49 patients) and TFC (N=56 patients) scales.

CONCLUSIONS

These results underscore the need to address apathy as a target for improving functional status, social satisfaction, and well-being in HD, even for individuals with early-stage HD.

Persistent symptoms after COVID-19: an Australian stratified random health survey on long COVID

OBJECTIVE

To determine the impact of persistent symptoms after coronavirus disease 2019 (COVID-19) in an Australian population.

DESIGN, SETTING, PARTICIPANTS

We conducted a statewide health survey of a stratified random sample of adults who had had a confirmed acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (COVID-19-positive group) and their close contacts (control group). The sample was drawn from Victoria's COVID-19 database between January 2020 and October 2022. Data were collected from 12 688 survey respondents between September 2022 and April 2023 (11 174 in the COVID-19-positive group and 1514 in the control group).

MAIN OUTCOME MEASURES

Persistent new symptoms, recovery, and daily function using validated questionnaires for fatigue, neurocognitive symptoms, anxiety, depression and quality of life.

RESULTS

At a mean of 12.6 months after infection, 4560 respondents in the COVID-19-positive group (39.1%; 95% CI, 37.9-40.3%) reported at least one persistent new symptom, compared with 216 respondents in the control group (20.8%; 95% CI, 18.5-23.1%). A total of 1656 respondents (14.2%; 95% CI, 13.4-15.0%) were classified as having clinical long COVID using the criteria of at least one persistent new symptom and less than 80% recovery three months after the infection. Of the respondents with clinical long COVID, 535 (3.2%; 95% CI, 2.6-3.8%) reported at least moderate problems with usual activities at 12 months after their infection. The proportion of respondents with clinical long COVID was lower for those with more recent infections. The risk factors for clinical long COVID were female sex, age 40-49 years, infection severity, chronic illness, and past anxiety or depression. Factors associated with a decreased risk of having clinical long COVID included infection when the Omicron strain was dominant and infection when the Delta strain was dominant, as compared with when the ancestral strain of the virus was dominant.

CONCLUSION

Persistent symptoms after COVID-19 are common, though with a lower incidence following infection from less virulent strains. Although long COVID can be largely managed in primary care, a minority of people who have persistent symptoms and impaired function may require specialist care pathways, the effectiveness of which should be a focus of future research.

The Impact of Functionality and Psychological Outcome on Social Engagement 3-months after Intracerebral Hemorrhage

BACKGROUND

Although it is well-known that intracerebral hemorrhage (ICH) is associated with physical and psychological morbidity, there is scant data on factors influencing social engagement after ICH. Understanding the relationship between functionality, psychological outcome and social engagement post-bleed may facilitate identification of patients at high risk for social isolation after ICH.

METHODS

Patients ≥18-years-old with non-traumatic ICH from January 2015-March 2023 were identified from the Neurological Emergencies Outcomes at NYU (NEON) registry. Data on discharge functionality were collected from the medical record. 3-months post-bleed, patients/their legally-authorized representatives (LARs) were contacted to complete Neuro-QoL social engagement, anxiety, depression, and sleep inventories. Patients were stratified by ability to participate in social roles and activities (good=T-score>50, poor=T-score≤50) and satisfaction with social roles and activities (high=T-score>50 and low=T-score≤50). Univariate comparisons were performed to evaluate the relationship between post-bleed social engagement and both functionality and psychological outcome using Pearson's chi-square, Fisher's Exact test, and Mann-Whitney U tests. Multivariate logistic regression was subsequently performed using variables that were significant on univariate analysis (p<0.05).

RESULTS

The social engagement inventories were completed for 55 patients with ICH; 29 (53 %) by the patient alone, 14 (25 %) by a LAR alone, and 12 (22 %) by both patient and LAR. 15 patients (27 %) had good ability to participate in social roles and activities and 10 patients (18 %) had high satisfaction with social roles and activities. Social engagement was associated with both functionality and psychological outcome on univariate analysis, but on multivariate analysis, it was only related to functionality; post-bleed ability to participate in social roles and activities was associated with discharge home, discharge GCS score, discharge mRS score, and discharge NIHSS score (p<0.05) and post-bleed satisfaction with social roles and activities was related to discharge mRS score and discharge NIHSS score (p<0.05).

CONCLUSION

In patients with nontraumatic ICH, social engagement post-bleed was related to discharge functionality, even when controlling for depression, anxiety, and sleep disturbance.

Career duration and later-life health conditions among former professional American-style football players

OBJECTIVES

Career duration is often used as a metric of neurotrauma exposure in studies of elite athletes. However, as a proxy metric, career length may not accurately represent causal factors, and associations with health outcomes may be susceptible to selection effects. To date, relationships between professional American-style football (ASF) career length and postcareer health remain incompletely characterised.

METHODS

We conducted a survey-based cross-sectional cohort study of former professional ASF players. Flexible regression methods measured associations between self-reported career duration and four self-reported health conditions: pain, arthritis, mood and cognitive symptoms. We also measured associations between career duration and four self-reported ASF exposures: prior concussion signs and symptoms (CSS), performance enhancing drugs, intracareer surgeries and average snaps per game. Models were adjusted for age and race.

RESULTS

Among 4189 former players (52±14 years of age, 39% black, 34% lineman position), the average career length was 6.7±3.9 professional seasons (range=1-20+). We observed inverted U-shaped relationships between career duration and outcomes (all p<0.001), indicating that adverse health effects were more common among men with intermediate career durations than those with shorter or longer careers. Similar findings were observed for play-related exposures (eg, CSS and snaps).

CONCLUSIONS

Relationships between ASF career duration and subsequent health status are non-linear. Attenuation of the associations among longer career players may reflect selection effects and suggest career length may serve as a poor proxy for true causal factors. Findings highlight the need for cautious use of career duration as a proxy exposure metric in studies of former athletes.

Sensor-Acquired Reachable Workspace (RWS) Correlates with Activities of Daily Living (ADL) Function in Stroke as Measured by Functional Independence Measure (FIM) Self-Care

Optimal upper extremity motor control and range of motion are necessary to achieve even the basic activities of daily living (ADL) function. Stroke, with resulting hemiparesis, can significantly and negatively impact an individual's ADL function. Functional Independence Measure (FIM) self-care score can provide an assessment of what aspects and to what degree ADL functions are impaired. FIM self-care assessment can also track changes in ADL function during stroke recovery and rehabilitation. Recently, the sensor-acquired 3D motion analysis of stroke patients' upper extremity has shown promise as a potential alternative to assess ADL function. This observational study evaluates whether the sensor-acquired upper extremity reachable workspace (RWS) measure correlates with clinician-evaluated FIM self-care score in stroke patients. Seventeen patients with stroke were enrolled in the study. FIM self-care, NeuroQoL upper extremity, and reachable workspace outcome measures (relative surface area, RSA) were collected upon rehabilitation hospital admission, at discharge, and at the 3-month visit. Pearson and Spearman's rank correlation coefficients as well as multiple linear regression analyses were used to determine the relationships between FIM self-care, NeuroQoL, and reachable workspace RSAs. Moderately strong correlation between total reachable workspace RSA and total FIM self-care score at discharge and at 3 months were noted (r = 0.619, r = 0.661, p < 0.05), and similarly strong correlation was also noted with the upper extremity NeuroQoL total score (r = 0.690, r = 0.815, p < 0.05). Multiple linear regression analyses revealed a change in average bilateral total RSA of 0.1 unit from admission to the 3-month follow-up correlated with a respective change in the FIM self-care score of 2.011 points (95%CI: 0.663-3.360). Longitudinal improvement in ADL function during stroke rehabilitation and recovery process is correlated with improvement in reachable workspace.

Neurologic Quality of Life Outcomes in Patients with Normal Pressure Hydrocephalus After Ventriculoperitoneal Shunt Placement: A Prospective Assessment of Cognition, Mobility, and Social Participation

BACKGROUND

Idiopathic normal pressure hydrocephalus (iNPH) typically presents with gait disturbances, cognitive decline, and urinary incontinence. Symptomatic improvement generally occurs following shunt placement, but limited evidence exists on the quality of life (QOL) metrics in iNPH. Therefore, we conducted a prospective study of the effect of shunt placement on QOL in iNPH patients, using Quality of Life in Neurologic Disorders (Neuro-QOL) metrics.

METHODS

Eligible patients underwent shunt placement after evidence of symptomatic improvement following temporary cerebrospinal fluid diversion via inpatient lumbar drain trial. Patients were administered short- and long-form Neuro-QOL assessments prior to shunt placement and at 6-month and 1-year postoperative timepoints to evaluate lower extremity mobility, cognitive function, and social roles and activities participation. Changes in QOL measures were analyzed using a repeated-measures linear mixed effects model.

RESULTS

There were 48 patients with a mean age of 75.4 ± 6.3 years. Average short-form mobility scores improved by 3.9 points (14.6%) at 6-month follow-up and by 6.2 points (23.2%) at 1-year follow-up compared with preoperative baseline (P = 0.027 and P = 0.0002, respectively). Short-form cognition scores increased by 5.2 points (22.4%) at 6 months and 10.9 points (47.0%) at 1 year postoperatively (P = 0.007 and P < 0.0001, respectively). On long-form assessment, social roles and activity participation scores improved by 29.3 points (23.4%) at 6 months and 31.6 points (25.2%) at 1 year after surgery compared to baseline (P = 0.028 and P = 0.02, respectively).

CONCLUSIONS

Our findings demonstrate that shunt placement leads to improved QOL in iNPH patients across multiple domains. Significant improvements in mobility, cognition, and social roles and activity participation are realized within the first 6 months and are sustained on 1-year follow-up.

Anxiety Symptoms and Disease Severity in Parkinson Disease

ABSTRACT

BACKGROUND: Anxiety is prevalent in Parkinson disease (PD), negatively affecting quality of life for patients and their families. Targeted anxiety interventions are needed that account for variables such as disease severity; however, there is insufficient evidence regarding the trajectory of anxiety along the disease course. OBJECTIVE: The aim of this study was to investigate the association between disease severity and anxiety symptoms in a PD sample. METHODS: This descriptive study used secondary data analyses of data from a web-based survey study of individuals with PD in the United States. Participants were 21 years or older, had access to the Internet, and were given a diagnosis of PD (N = 72). We performed multiple regression analyses to assess the relationship between patient-reported disease severity and anxiety symptoms. RESULTS: There was a statistically significant association between disease severity and anxiety symptoms in people with PD, after controlling for all 5 explanatory variables (sex, age, wearing off, disease severity, and disease duration) ( P < .001). Age and wearing off PD medication also had statistically significant, although smaller, effects on anxiety symptoms ( P < .05). CONCLUSION: Disease severity was related to increased anxiety symptoms among individuals with PD. Anxiety intervention research is needed, and future studies should account for variations in disease severity and medication effects in both intervention and study design.

Age of First Exposure Does Not Relate to Post-Career Health in Former Professional American-Style Football Players

OBJECTIVE

Prior studies examining small samples of symptomatic former professional football players suggest that earlier age of first exposure (AFE) to American football is associated with adverse later life health outcomes. This study examined a larger, more representative sample of former professional American football players to assess associations between AFE before age 12 (AFE < 12) and clinical outcomes compared with those who started at age 12 or older (AFE 12 +).

METHODS

Former professional American football players who completed a questionnaire were dichotomized into AFE < 12 and AFE 12 + . AFE groups were compared on outcomes including symptoms of depression and anxiety, perceived cognitive difficulties, neurobehavioral dysregulation, and self-reported health conditions (e.g., headaches, sleep apnea, hypertension, chronic pain, memory loss, dementia/Alzheimer's disease, and others).

RESULTS

Among 4189 former professional football players (aged 52 ± 14 years, 39% self-reported as Black), univariable associations with negligible effect sizes were seen with AFE < 12, depressive symptoms (p = 0.03; η2 = 0.001), and anxiety-related symptoms (p = 0.02; η2 = 0.001) only. Multivariable models adjusting for age, race, body mass index, playing position, number of professional seasons, and past concussion burden revealed no significant relationships between AFE < 12 and any outcome. Linear and non-linear models examining AFE as a continuous variable showed similar null results.

CONCLUSIONS

In a large cohort of former professional American-style football players, AFE was not independently associated with adverse later life outcomes. These findings are inconsistent with smaller studies of former professional football players. Studies examining AFE in professional football players may have limited utility and generalizability regarding policy implications for youth sports.

Motor and Non-Motor Factors of Concern About Falling and Fear of Falling in Multiple Sclerosis

BACKGROUND AND PURPOSE

Despite the frequency of concern about falling (CAF) and fear of falling (FOF) in multiple sclerosis (MS), there remains a lack of clarity between FOF and CAF, though persons with MS have indicated that CAF and FOF are distinct constructs. Our team previously developed and validated a new questionnaire, the Concern and Fear of Falling Evaluation (CAFFE), to assess these concepts. This study aimed to examine CAF and FOF prevalence, and determine relationships among CAF, FOF, and self-reported motor, cognitive, and psychological function in MS relapsing (RRMS) and progressive (PMS) subtypes.

METHODS

In a single online survey, participants with MS completed questions about CAF and FOF, demographic information, the CAFFE, and self-report measures of motor, cognitive, and psychological function.

RESULTS

A total of 912 individuals completed the survey. Persons with PMS reported greater CAF (80.1%) and FOF (59.1%) than those with RRMS (57.0% and 41.6%, respectively). Persons with PMS endorsing FOF (yes/no) reported greater FOF on the CAFFE, greater avoidance behavior, greater walking impairment, and poorer motor function than people with RRMS ( P < 0.001). Self-reported motor function, walking impairment, and avoidance behavior were highly correlated to the CAFFE across the overall sample ( P < 0.001).

DISCUSSIONS AND CONCLUSIONS

These findings underscore the disparity between CAF and FOF, emphasize the importance of evaluating CAF and FOF in MS subtypes separately, and highlight both motor and non-motor factors contributing to CAF and FOF. Future work should focus on interventions that incorporate motor, cognitive, and psychological components to address CAF and FOF.

Optimizing Detection and Prediction of Cognitive Function in Multiple Sclerosis With Ambulatory Cognitive Tests: Protocol for the Longitudinal Observational CogDetect-MS Study

BACKGROUND

Cognitive dysfunction is a common problem in multiple sclerosis (MS). Progress toward understanding and treating cognitive dysfunction is thwarted by the limitations of traditional cognitive tests, which demonstrate poor sensitivity and ecological validity. Ambulatory methods of assessing cognitive function in the lived environment may improve the detection of subtle changes in cognitive function and the identification of predictors of cognitive changes and downstream effects of cognitive change on other functional domains.

OBJECTIVE

This paper describes the study design and protocol for the Optimizing Detection and Prediction of Cognitive Function in Multiple Sclerosis (CogDetect-MS) study, a 2-year longitudinal observational study designed to examine short- and long-term changes in cognition, predictors of cognitive change, and effects of cognitive change on social and physical function in MS.

METHODS

Participants-ambulatory adults with medically documented MS-are assessed over the course of 2 years on an annual basis (3 assessments: T1, T2, and T3). A comprehensive survey battery, in-laboratory cognitive and physical performance tests, and 14 days of ambulatory data collection are completed at each annual assessment. The 14-day ambulatory data collection includes continuous wrist-worn accelerometry (to measure daytime activity and sleep); ecological momentary assessments (real-time self-report) of somatic symptoms, mood, and contextual factors; and 2 brief, validated cognitive tests, administered by smartphone app 4 times per day. Our aim was to recruit 250 participants. To ensure standard test protocol administration, all examiners passed a rigorous examiner certification process. Planned analyses include (1) nonparametric 2-tailed t tests to compare in-person to ambulatory cognitive test scores; (2) mixed effects models to examine cognitive changes over time; (3) mixed effects multilevel models to evaluate whether ambulatory measures of physical activity, sleep, fatigue, pain, mood, and stress predict changes in objective or subjective measures of cognitive functioning; and (4) mixed effects multilevel models to examine whether ambulatory measures of cognitive functioning predict social and physical functioning over short (within-day) and long (over years) time frames.

RESULTS

The study was funded in August 2021 and approved by the University of Michigan Medical Institutional Review Board on January 27, 2022. A total of 274 adults with MS (first participant enrolled on May 12, 2022) have been recruited and provided T1 data. Follow-up data collection will continue through March 2026.

CONCLUSIONS

Results from the CogDetect-MS study will shed new light on the temporal dynamics of cognitive function, somatic and mood symptoms, sleep, physical activity, and physical and social function. These insights have the potential to improve our understanding of changes in cognitive function in MS and enable us to generate new interventions to maintain or improve cognitive function in those with MS.

Cognitive behavioral interventions for depression and anxiety in adults with neurological disorders: a systematic review and meta-analysis

We examined the efficacy of cognitive and behavioral interventions for improving symptoms of depression and anxiety in adults with neurological disorders. A pre-registered systematic search of Cochrane Central Register of Controlled Trials, MEDLINE, PsycINFO, Embase, and Neurobite was performed from inception to May 2024. Randomized controlled trials (RCTs) which examined the efficacy of cognitive and behavioral interventions in treating depression and/or anxiety among adults with neurological disorders were included. Estimates were pooled using a random-effects meta-analysis. Subgroup analyses and meta-regression were performed on categorical and continuous moderators, respectively. Main outcomes were pre- and post-intervention depression and anxiety symptom scores, as reported using standardized measures. Fifty-four RCTs involving 5372 participants with 11 neurological disorders (including multiple sclerosis, epilepsy, stroke) were included. The overall effect of interventions yielded significant improvements in both depression (57 arms, Hedges' g = 0.45, 95% confidence interval [CI] 0.35-0.54) and anxiety symptoms (29 arms, g = 0.38, 95% CI 0.29-0.48), compared to controls. Efficacy was greater in studies which employed a minimum baseline symptom severity inclusion criterion for both outcomes, and greater in trials using inactive controls for depression only. There was also evidence of differential efficacy of interventions across the neurological disorder types and the outcome measure used. Risk of bias, intervention delivery mode, intervention tailoring for neurological disorders, sample size, and study year did not moderate effects. Cognitive and behavioral interventions yield small-to-moderate improvements in symptoms of both depression and anxiety in adults with a range of neurological disorders.

Perceived Chronic Traumatic Encephalopathy and Suicidality in Former Professional Football Players

Importance

Participation in American-style football (ASF) has been linked to chronic traumatic encephalopathy neuropathological change (CTE-NC), a specific neuropathologic finding that can only be established at autopsy. Despite being a postmortem diagnosis, living former ASF players may perceive themselves to have CTE-NC. At present, the proportion and clinical correlates of living former professional ASF athletes with perceived CTE who report suicidality are unknown.

Objective

To determine the proportion, clinical correlates, and suicidality of living former professional ASF players with perceived CTE.

Design, Setting, and Participants

A cross-sectional study within the Football Players Health Study at Harvard University was conducted from 2017 to 2020. Using electronic and paper surveys, this population-based study included former ASF players who contracted with a professional league from 1960 to 2020 and volunteered to fill out a baseline survey. Data for this study were analyzed from June 2023 through March 2024.

Exposures

Data included demographics, football-related exposures (eg, position, career duration), and current health problems (anxiety, attention-deficit/hyperactivity disorder, depression, diabetes, emotional and behavioral dyscontrol symptoms, headache, hyperlipidemia, hypertension, low testosterone level, pain, sleep apnea, and subjective cognitive function).

Main Outcomes and Measures

The proportion of participants reporting perceived CTE. Univariable and multivariable models were used to determine clinical and suicidality correlates of perceived CTE.

Results

Among 4180 former professional ASF players who volunteered to fill out a baseline survey, 1980 (47.4%) provided follow-up data (mean [SD] age, 57.7 [13.9] years). A total of 681 participants (34.4%) reported perceived CTE. Subjective cognitive difficulties, low testosterone level, headache, concussion signs and symptoms accrued during playing years, depressive/emotional and behavioral dyscontrol symptoms, pain, and younger age were significantly associated with perceived CTE. Suicidality was reported by 171 of 681 participants with perceived CTE (25.4%) and 64 of 1299 without perceived CTE (5.0%). After adjusting for established suicidality predictors (eg, depression), men with perceived CTE remained twice as likely to report suicidality (odds ratio, 2.06; 95% CI, 1.36-3.12; P < .001).

Conclusions and Relevance

This study found that approximately one-third of living former professional ASF players reported perceived CTE. Men with perceived CTE had an increased prevalence of suicidality and were more likely to have health problems associated with cognitive impairment compared with men without perceived CTE. Perceived CTE represents a novel risk factor for suicidality and, if present, should motivate the diagnostic assessment and treatment of medical and behavioral conditions that may be misattributed to CTE-NC.

Pomalidomide for Epistaxis in Hereditary Hemorrhagic Telangiectasia

BACKGROUND

Hereditary hemorrhagic telangiectasia (HHT) is characterized by extensive telangiectasias and arteriovenous malformations. The primary clinical manifestation is epistaxis that results in iron-deficiency anemia and reduced health-related quality of life.

METHODS

We conducted a randomized, placebo-controlled trial to evaluate the safety and efficacy of pomalidomide for the treatment of HHT. We randomly assigned patients, in a 2:1 ratio, to receive pomalidomide at a dose of 4 mg daily or matching placebo for 24 weeks. The primary outcome was the change from baseline through week 24 in the Epistaxis Severity Score (a validated bleeding score in HHT; range, 0 to 10, with higher scores indicating worse bleeding). A reduction of 0.71 points or more is considered clinically significant. A key secondary outcome was the HHT-specific quality-of-life score (range, 0 to 16, with higher scores indicating more limitations).

RESULTS

The trial was closed to enrollment in June 2023 after a planned interim analysis met a prespecified threshold for efficacy. A total of 144 patients underwent randomization; 95 patients were assigned to receive pomalidomide and 49 to receive placebo. The baseline mean (±SD) Epistaxis Severity Score was 5.0±1.5, a finding consistent with moderate-to-severe epistaxis. At 24 weeks, the mean difference between the pomalidomide group and the placebo group in the change from baseline in the Epistaxis Severity Score was -0.94 points (95% confidence interval [CI], -1.57 to -0.31; P = 0.004). The mean difference in the changes in the HHT-specific quality-of-life score between the groups was -1.4 points (95% CI, -2.6 to -0.3). Adverse events that were more common in the pomalidomide group than in the placebo group included neutropenia, constipation, and rash.

CONCLUSIONS

Among patients with HHT, pomalidomide treatment resulted in a significant, clinically relevant reduction in epistaxis severity. No unexpected safety signals were identified. (Funded by the National Heart, Lung, and Blood Institute; PATH-HHT Clinicaltrials.gov number, NCT03910244).

The psychometric properties of the Quality of Life in Neurological Disorders (Neuro-QoL) measurement system in neurorehabilitation populations: a systematic review

OBJECTIVE

To systematically review the literature of existing evidence on the measurement properties of the Quality of Life in Neurological Disorders (Neuro-QoL) measurement system among neurorehabilitation populations.

DATA SOURCES

The Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) guided this systematic review in which we searched nine electronic databases and registries, and hand-searched reference lists of included articles.

STUDY SELECTION

Two independent reviewers screened selected articles and extracted data from 28 included studies.

DATA EXTRACTION

COSMIN's approach guided extraction and synthesizing measurement properties evidence (insufficient, sufficient), and the modified GRADE approach guided synthesizing evidence quality (very-low, low, moderate, high) by diagnosis.

DATA SYNTHESIS

Neuro-QoL has sufficient measurement properties when used by individuals with Huntington's disease, Multiple Sclerosis, Parkinson's disease, stroke, lupus, cognitive decline, and amyotrophic lateral sclerosis. The strongest evidence is for the first four conditions, where test-retest reliability, construct validity, and responsiveness are nearly always sufficient (GRADE: moderate-high). Structural validity is assessed only in multiple sclerosis and stroke but is often insufficient (GRADE: moderate-high). Criterion validity is sufficient in some stroke and Huntington's disease domains (GRADE: high). Item response theory analyses were reported for some stroke domains only. There is limited, mixed evidence for responsiveness and measurement error (GRADE: moderate-high), and no cross-cultural validity evidence CONCLUSIONS: Neuro-QoL domains can describe and evaluate patients with Huntington's disease, multiple sclerosis, Parkinson's disease, and stroke, but predictive validity evidence would be beneficial. In the other conditions captured in this review, a limited number of Neuro-QoL domains have evidence for descriptive use only. For these conditions, further evidence of structural validity, measurement error, cross-cultural validity and predictive validity would enhance the use and interpretation of Neuro-QoL.

Detecting fatigue in multiple sclerosis through automatic speech analysis

Multiple sclerosis (MS) is a chronic neuroinflammatory disease characterized by central nervous system demyelination and axonal degeneration. Fatigue affects a major portion of MS patients, significantly impairing their daily activities and quality of life. Despite its prevalence, the mechanisms underlying fatigue in MS are poorly understood, and measuring fatigue remains a challenging task. This study evaluates the efficacy of automated speech analysis in detecting fatigue in MS patients. MS patients underwent a detailed clinical assessment and performed a comprehensive speech protocol. Using features from three different free speech tasks and a proprietary cognition score, our support vector machine model achieved an AUC on the ROC of 0.74 in detecting fatigue. Using only free speech features evoked from a picture description task we obtained an AUC of 0.68. This indicates that specific free speech patterns can be useful in detecting fatigue. Moreover, cognitive fatigue was significantly associated with lower speech ratio in free speech (ρ = -0.283, p = 0.001), suggesting that it may represent a specific marker of fatigue in MS patients. Together, our results show that automated speech analysis, of a single narrative free speech task, offers an objective, ecologically valid and low-burden method for fatigue assessment. Speech analysis tools offer promising potential applications in clinical practice for improving disease monitoring and management.

Neuroinflammatory Biomarkers and Their Associations With Cognitive, Affective, and Functional Outcomes 3 to 12 Months After a Traumatic Brain Injury: A Pilot Study

BACKGROUND

Neuroinflammation is an important feature of traumatic brain injury (TBI) that remains poorly understood in the 3- to 12-month period post-TBI.

OBJECTIVE

The purpose of our pilot study was to examine the relationships between biomarkers of neuroinflammation and functional outcomes in TBI patients 3 to 12 months postinjury.

METHODS

TBI patients (n = 36) 3 to 12 months post-TBI were recruited from a South Florida TBI clinic from May 2022 to June 2023. The Disability Rating Scale, Satisfaction with Life Scale, NIH Toolbox Sorting Working Memory, Neuro-Quality of Life Cognitive Function, Anxiety, Depression, and Sleep assessments were performed. Multiple plasma biomarkers were assayed. Analysis of variance was used to compare between-group results. Linear regression was performed to analyze relationships between biomarkers and outcomes.

RESULTS

Brain-derived neurotrophic factor concentrations were higher as postinjury time interval increased and were associated with cognitive battery outcomes. S-100β and glial fibrillary acidic protein were associated with anxiety score and hospital length of stay; S-100β was also associated with depression. Interleukin 6 was associated with cognitive function score and time since injury.

CONCLUSIONS

We found S-100β, glial fibrillary acidic protein, Interleukin 6, and brain-derived neurotrophic factor to play a larger role in the TBI recovery period than other biomarkers examined. Clinicians should continue to monitor for symptoms post-TBI, as the neuroinflammatory process continues to persist even into the later rehabilitation stage.

Intraindividual variability in post-stroke cognition and its relationship with activities of daily living and social functioning: an ecological momentary assessment approach

INTRODUCTION

Ecological momentary assessment (EMA) is a methodological approach to studying intraindividual variation over time. This study aimed to use EMA to determine the variability of cognition in individuals with chronic stroke, identify the latent classes of cognitive variability, and examine any differences in daily activities, social functioning, and neuropsychological performance between these latent classes.

METHODS

Participants (N = 202) with mild-to-moderate stroke and over 3-month post-stroke completed a study protocol, including smartphone-based EMA and two lab visits. Participants responded to five EMA surveys daily for 14 days to assess cognition. They completed patient-reported measures and neuropsychological assessments during lab visits. Using latent class analysis, we derived four indicators to quantify cognitive variability and identified latent classes among participants. We used ANOVA and Chi-square to test differences between these latent classes in daily activities, social functioning, and neuropsychological performance.

RESULTS

The latent class analysis converged on a three-class model. The moderate and high variability classes demonstrated significantly greater problems in daily activities and social functioning than the low class. They had significantly higher proportions of participants with problems in daily activities and social functioning than the low class. Neuropsychological performance was not statistically different between the three classes, although a trend approaching statistically significant difference was observed in working memory and executive function domains.

DISCUSSION

EMA could capture intraindividual cognitive variability in stroke survivors. It offers a new approach to understanding the impact and mechanism of post-stroke cognitive problems in daily life and identifying individuals benefiting from self-regulation interventions.

Negative disease-related stigma 3-months after hemorrhagic stroke is related to functional outcome and female sex

OBJECTIVES

The objective of this study was to determine factors associated with negative disease-related stigma after hemorrhagic stroke.

MATERIALS AND METHODS

Patients with non-traumatic hemorrhage (ICH or SAH) admitted between January 2015 and February 2021 were assessed by telephone 3-months after discharge using the Quality of Life in Neurological Disorders (Neuro-QoL) Negative Disease-Related Stigma Short Form inventory. We evaluated the relationship between disease-related stigma (T-score >50) and pre-stroke demographics, admission data, and poor functional outcome (3-month mRS score 3-5 and Barthel Index <100).

RESULTS

We included 89 patients (56 ICH and 33 SAH). The median age was 63 (IQR 50-69), 43 % were female, and 67 % graduated college. Admission median GCS score was 15 (IQR 13-15) and APACHE II score was 12 (IQR 9-17). 31 % had disease-related stigma. On univariate analysis, disease-related stigma was associated with female sex, non-completion of college, GCS score, APACHE II score, and 3-month mRS score (all p < 0.05). On multivariate analysis, disease-related stigma was associated with female sex (OR = 3.72, 95 % CI = 1.23-11.25, p = 0.02) and 3-month Barthel Index <100 (OR = 3.46, 95 % CI = 1.13-10.64, p = 0.03) on one model, and female sex (OR = 3.75, 95 % CI = 1.21-11.58, p = 0.02) and 3-month mRS score 3-5 (OR = 4.23, 95 % CI = 1.21-14.75, p = 0.02) on a second model.

CONCLUSION

Functional outcome and female sex are associated with disease-related stigma 3-months after hemorrhagic stroke. Because stigma may negatively affect recovery, there is a need to understand the relationship between these factors to mitigate stroke-related stigma.

Family characteristics and childcare patterns associated with early social functioning in cancer-bereaved parents

BACKGROUND

Bereaved parents experience life-long grief after the death of their child from cancer. Parents who can integrate their grief and maintain their social functioning early in bereavement, even in the setting of concurrent psychosocial distress, have improved outcomes. Identifying the factors associated with bereaved parents' early social functioning can guide future supportive interventions.

METHODS

The authors surveyed parents of children who died from cancer at two large centers 6-24 months after death, assessing bereavement experiences using validated and pilot tested tools. Univariable and multivariable logistical regression models were used to examine which family and child demographic, treatment, and end-of-life (EOL) factors were associated with maintained parental social functioning (T scores ≥40 on the Patient-Reported Outcomes Measurement Information System Ability to Participate in Social Roles and Activities-Short Form questionnaire).

RESULTS

One hundred twenty-eight parents of 88 children participated (38% household response rate); most parents identified as female (63%) and White (88%). Parents' median age was 47 years (interquartile range, 10 years); and the median time from the child's death to survey completion was 13 months (interquartile range, 10 months). In multivariate modeling, parents without household material hardship and those who felt prepared for EOL circumstances had increased odds of maintained social functioning (odds ratio, 4.7 [95% confidence interval, 1.6-13.7; p < .004] and 5.5 [95% confidence interval, 1.9-15.9; p < .002], respectively).

CONCLUSIONS

Parents who felt prepared for their child's EOL and those without household material hardship were more likely to have maintained social functioning in the first 2 years after their child's death. Interventions targeting EOL preparedness and alleviating household material hardship may improve bereavement outcomes.

The Impact of Death and Dying Education for Undergraduate Students During the COVID-19 Pandemic

Fear of COVID-19 may make the imminence of death prescient for undergraduate students, increasing death anxiety and worsening mental health. Formal death education may provide benefits such as reduced fear of COVID-19 and death anxiety, and improved mental health. In this study, 86 undergraduate students completed a pre- and post-semester online questionnaire on fear of COVID-19, death anxiety, and mental health outcomes. Findings indicate indirect effects of death anxiety on fear of COVID-19 to anxiety. Moreover, fear of COVID-19, individual concerns about death, and death anxiety were reduced over the semester for undergraduate students in formal death education.

Sleep deprivation and recovery: Endurance racing as a novel model

The aim of this study was to investigate sleep-wake behavior and gain insights into perceived impairment (sleep, fatigue, and cognitive function) of athletes competing in two international multi-day adventure races. Twenty-four athletes took part across two independent adventure races: Queensland, Australia and Alaska, USA. Individual sleep periods were determined via actigraphy, and racers self-reported their perceived sleep disturbances, sleep impairment, fatigue and cognitive function. Each of these indices was calculated for pre-, during- and post-race periods. Sleep was severely restricted during the race period compared to pre-race (Queensland, 7:46 [0:29] vs. 2:50 [1:01]; Alaska, 7:39 [0:58] vs. 2:45 [2:05]; mean [SD], hh:mm). As a result, there was a large cumulative sleep debt at race completion, which was not 'reversed' in the post-race period (up to 1 week). The deterioration in all four self-reported scales of perceived impairment during the race period was largely restored in the post-race period. This is the first study to document objective sleep-wake behaviors and subjective impairment of adventure racers, in the context of two geographically diverse, multi-day, international adventure races. Measures of sleep deprivation indicate that sleep debt was extreme and did not recover to pre-race levels within 1 week following each race. Despite this objective debt continuing, perceived impairment returned to pre-race levels quickly post-race. Therefore, further examination of actual and perceived sleep recovery is warranted. Adventure racing presents a unique scenario to examine sleep, performance and recovery.

Fatigue, Fogginess, and Sleep Complaints: Presence and Impact on Functioning After Childhood Traumatic Brain Injury

PURPOSE

The purpose of this study was to examine the occurrence and impact of fatigue, fogginess, and sleep complaints on functioning at 3, 6, 10, and 16 months after childhood traumatic brain injury (TBI).

METHOD

Eighty-eight caregivers completed online surveys regarding their children with TBI, with 17 participants included at the final time point. Measures included questions related to demographic and injury characteristics, executive functioning, social relations, health-related quality of life, and fatigue, fogginess, and sleep complaints.

RESULTS

Fatigue, fogginess, and sleep complaints were persistent and ultimately increased at 16 months postinjury. Over half of the participants were experiencing each symptom at 16 months postinjury (i.e., 52.94% fatigue and fogginess, 58.82% sleep complaints). At 16 months postinjury, fatigue was significantly associated with female sex, and fatigue and sleep complaints were significantly associated with lower physical quality of life, but no other differences were found with symptoms and current functioning.

CONCLUSIONS

The results of this study support that fatigue, fogginess, and sleep complaints can persist (from baseline, from postinjury, and in fluctuation) chronically for about half of the children with TBI but little association or impact on other domains of functioning. The present study supports the continued investigation of fatigue, fogginess, and sleep complaints after childhood brain injury, but further investigation with a larger sample size is necessary to inform clinical practices for assessment and management, particularly for speech-language pathologists in rehabilitation and educational settings.

Self-Report of Changes in Cognitive-Communication Function and Social Engagement Among Adults With Cancer-Related Cognitive Impairment

PURPOSE

This study aimed to examine the prevalence of cognitive-communication deficits in adult cancer survivors who reported experiencing cancer-related cognitive impairment (CRCI). The study also aimed to determine how these problems impact their ability to engage socially and find satisfaction in their social roles.

METHOD

This study employed a cross-sectional survey to collect data from adult cancer survivors. The survey included questions on demographic characteristics, self-perceived cognitive-communication abilities, social engagement, and satisfaction with social participation. Data analysis included descriptive statistics, Spearman rank-order correlation, Mann-Whitney U tests, and Kruskal-Wallis H tests.

RESULTS

Of 172 participants, 78% completed the survey, with 109 self-reporting CRCI. The participants predominantly had breast cancer, and most were diagnosed with Stage II cancers. The results indicated self-perceived impairment in various cognitive-communication domains, with functional daily communication being the most affected. Participants reported more difficulty participating in social roles and activities than their overall satisfaction with social participation. This study explored the relationships between cognitive-communication scores and social engagement, considering variables such as education, cancer type, stage, age, and treatment.

CONCLUSIONS

This study underscores the multidimensional nature of CRCI, emphasizing the importance of addressing both cognitive-communication and social aspects in interventions and support services. It highlights the clinical implications for speech-language pathology, suggesting a potential role in identifying and addressing cognitive-communication deficits. Future research needs are discussed.

Correlates of Self-Reported Executive Function Impairment Among Medicaid Beneficiaries With Type 2 Diabetes

Aims

Executive function (EF) impairment is associated with poorer outcomes for individuals with type 2 diabetes. Previous research has identified risk factors for EF impairment, but many of these are also associated with type 2 diabetes. To address this issue, this study identified relevant variables from the literature and compared their association with EF in a sample of people with type 2 diabetes.

Methods

Adult members of a Medicaid health plan diagnosed with type 2 diabetes were enrolled in a social needs intervention trial. Using baseline data from the trial, bivariate and multivariable regression analyses examined associations between EF and demographic, health, and psychosocial factors.

Results

When controlling for other factors, we identified six significant correlates of EF impairment: age (β = 0.10), education (college vs. no college; β = -0.38), depression symptoms (β = 0.18), comorbidity burden (β = 0.21), diabetes-related distress (β = 0.14), and future time orientation (β = -0.13).

Conclusion

Our analysis identified several factors associated with greater EF impairment, which may interfere with diabetes self-management. Providers should consider these factors when prescribing treatments and determine whether additional resources or accommodations are warranted.

Exploring Health-Related Social Needs and Components of Social Competence Following Childhood Traumatic Brain Injury

PURPOSE

Health-related social needs (HRSNs) impact general health care and educational outcomes for children with traumatic brain injury (TBI) and their families. Furthermore, children with TBI of all severities experience negative social competence outcomes chronically postinjury. However, studies have not investigated the relationship between HRSNs and social competence outcomes for children after TBI. The aim of this study was to identify the relationship between HRSNs and components of social competence (i.e., social skills, social communication, family functioning, and behavioral domains per the biopsychosocial framework for social competence) for children with TBI, per parent report.

METHOD

This study used a prospective, cross-sectional study design with a convenience sample. Online surveys were completed by parents of children with TBI (N = 22). On average, children with TBI were 4.84 years old at the time of their TBI and 9.24 years old at the time of study participation.

RESULTS

Having a parent identify an HRSN in the domain of mental health was associated with social communication and family functioning difficulties for children with TBI. Statistically significant relationships were found between social communication and family functioning, externalizing behavior, and total behavior; family functioning and social relations; and family functioning and externalizing behavior.

CONCLUSIONS

The findings of this study support that children with TBI experience chronic deficits in components of social competence, and HRSNs are associated with these outcomes. Further research needs to consider HRSNs to improve equitable prevention, supports, and services for children with TBI.

Poststroke Communication Ability Predicts Patient-Informant Discrepancies in Reported Activities and Participation

BACKGROUND

Participation in life situations has been identified by people with aphasia (PWA) as an ultimate outcome of rehabilitation and is often measured with patient-reported outcome measures (PROMs) or informant-reported measures. It is known that PWA and informants do not always produce similar scores on measures of activities and participation. However, systematic differences between PWA and informants and the causes of these differences are not well understood. Here, we investigated these differences as a function of language impairment, perceived level of activity and participation success, and depressive symptoms.

METHOD

Participants were 29 PWA-informant dyads who completed a performance-based language assessment and three measures related to different aspects of activities and participation. Outcome variables were PWA-informant difference scores in the activities and participation measures.

RESULTS

PWA ratings of activities and participation were not statistically significantly associated with performance-based language severity. Hierarchical regression models with both language impairment and informant-reported scores as predictor variables explained 53%-71% of the variance in PWA-informant difference scores (all p < .05). In particular, mild communication challenges were associated with the PWA reporting significantly worse participation than the informant perceived. In contrast, more severe communication challenges were associated with the PWA reporting significantly better participation than the informant perceived.

DISCUSSION

These findings highlight the importance of measuring participation by PROM. The PWA's experience of participation is not related to their level of language impairment and is predictably different from their care partners' perspective. As others have also reported, "mild" aphasia is not so mild to the PWA. Similarly, "severe" may not be so severe to the PWA. Further research is needed to connect these findings with counseling and caregiver education. Research on response processes (e.g., response shift) is also warranted.

Effect of a Smartphone App (S-Check) on Actual and Intended Help-Seeking and Motivation to Change Methamphetamine Use Among Adult Consumers of Methamphetamine in Australia: Randomized Waitlist-Controlled Trial

BACKGROUND

Interventions are required that address delays in treatment-seeking and low treatment coverage among people consuming methamphetamine.

OBJECTIVE

We aim to determine whether a self-administered smartphone-based intervention, the "S-Check app" can increase help-seeking and motivation to change methamphetamine use, and determine factors associated with app engagement.

METHODS

This study is a randomized, 28-day waitlist-controlled trial. Consenting adults residing in Australia who reported using methamphetamine at least once in the last month were eligible to download the app for free from Android or iOS app stores. Those randomized to the intervention group had immediate access to the S-Check app, the control group was wait-listed for 28 days before gaining access, and then all had access until day 56. Actual help-seeking and intention to seek help were assessed by the modified Actual Help Seeking Questionnaire (mAHSQ), modified General Help Seeking Questionnaire, and motivation to change methamphetamine use by the modified readiness ruler. χ2 comparisons of the proportion of positive responses to the mAHSQ, modified General Help Seeking Questionnaire, and modified readiness ruler were conducted between the 2 groups. Logistic regression models compared the odds of actual help-seeking, intention to seek help, and motivation to change at day 28 between the 2 groups. Secondary outcomes were the most commonly accessed features of the app, methamphetamine use, feasibility and acceptability of the app, and associations between S-Check app engagement and participant demographic and methamphetamine use characteristics.

RESULTS

In total, 560 participants downloaded the app; 259 (46.3%) completed eConsent and baseline; and 84 (32.4%) provided data on day 28. Participants in the immediate access group were more likely to seek professional help (mAHSQ) at day 28 than those in the control group (n=15, 45.5% vs n=12, 23.5%; χ21=4.42, P=.04). There was no significant difference in the odds of actual help-seeking, intention to seek help, or motivation to change methamphetamine use between the 2 groups on the primary logistic regression analyses, while in the ancillary analyses, the imputed data set showed a significant difference in the odds of seeking professional help between participants in the immediate access group compared to the waitlist control group (adjusted odds ratio 2.64, 95% CI 1.19-5.83, P=.02). For participants not seeking help at baseline, each minute in the app increased the likelihood of seeking professional help by day 28 by 8% (ratio 1.08, 95% CI 1.02-1.22, P=.04). Among the intervention group, a 10-minute increase in app engagement time was associated with a decrease in days of methamphetamine use by 0.4 days (regression coefficient [β] -0.04, P=.02).

CONCLUSIONS

The S-Check app is a feasible low-resource self-administered intervention for adults in Australia who consume methamphetamine. Study attrition was high and, while common in mobile health interventions, warrants larger studies of the S-Check app.

Safety and Feasibility of Stereotactic Radiosurgery for Patients with 15 or more Brain Metastases

Background

Current standard of care treatment for patients with ≥15 brain metastases (BM) is whole brain radiation therapy (WBRT), despite poor neurocognitive outcomes. We analyzed our institutional experience of treating these patients with stereotactic radiosurgery (SRS), with the aim of evaluating safety, cognitive outcomes, and survival metrics.

Methods

Patients who received SRS for ≥15 BMs in 1 to 5 fractions from 2014 to 2022 were included. Cognitive outcomes were objectively evaluated using serial Patient-Reported Outcome Measurement Information System (PROMIS) scores. The Kaplan-Meier method was used for survival analysis and log-rank test for intergroup comparisons.

Results

Overall, 118 patients underwent 124 courses of LINAC-based SRS. The median number of lesions treated per course was 20 (range, 15-94). Most patients received fractionated SRS to a dose of 24 Gy in 3 fractions (81.5%). At the time of SRS, 19.4% patients had received prior WBRT, and 24.2% had received prior SRS. The rate of any grade radiation necrosis (RN) and grade ≥3 RN were 15.3% and 3.2%, respectively. When evaluating longitudinal PROMIS score trends, 25 of 31 patients had a stable/improved PROMIS score. Patients who did not receive prior brain RT had a longer median survival (7.4 months vs 4.6 months, P = .034). The 12m local control was 97.6%, and the cumulative incidence of distant intracranial failure, with death as a competing event, was 46% (95% CI, 36%, 55%). One year freedom from neurologic death, leptomeningeal disease, and salvage WBRT were 89%, 94.6%, and 84%, respectively.

Conclusion

We present here one of the largest studies evaluating SRS for patients with ≥15 BMs. SRS was safe, had favorable cognitive outcomes, and had comparable survival outcomes to contemporary studies evaluating WBRT in this population. Treatment-naïve patients had a median survival of >6 months, long enough to benefit from cognitive sparing with SRS. Our study supports randomized studies comparing SRS and hippocampal avoidance WBRT approaches for these patients.

Adults with cerebral palsy and functional decline: A cross-sectional analysis of patient-reported outcomes from a novel North American registry

BACKGROUND

Adults with cerebral palsy (CP) have unique healthcare needs and risks, including high risk of functional decline. Understanding functional decline is an area of priority for CP research.

OBJECTIVE

Describe factors associated with patient-reported changes in function among adults with CP living in the community.

METHODS

Cross-sectional analysis of adult patient-reported outcomes collected by the CP Research Network (CPRN) Community Registry.

RESULTS

Participants included 263 respondents (76% female (n = 200); mean age 42 years (SD 14); 95% White (n = 249); 92% non-Hispanic (n = 241)). Many reported functional changes, most commonly a decline in gross motor function since childhood (n = 158, 60%). Prevalence of gross motor decline varied significantly by Gross Motor Function Classification System (GMFCS) level (p < 0.001), but neither hand function decline (p = 0.196) nor communication decline (p = 0.994) differed by GMFCS. All types of decline increased with increasing age, with statistically significant differences between age groups (p < 0.001 gross motor; p = 0.003 hand function; p = 0.004 communication). Those with spastic CP (n = 178) most commonly reported gross motor functional decline (n = 108/178, 60.7%). However, the prevalence of gross motor decline did not significantly differ between those with spastic CP and those without spastic CP (p = 0.789).

CONCLUSIONS

Many adults in the CPRN Community Registry reported functional decline, most commonly in gross motor function. Functional decline across domains increased with age. Further research into risk stratification and preventive and rehabilitative measures is needed to address functional decline across the lifespan.
