Climate-limited vegetation change in the conterminous United States of America.

The effects of climate change on vegetation composition and distribution are evident in different ecosystems around the world. Although some climate-derived alterations on vegetation are expected to result in changes in lifeform fractional cover, disentangling the direct effects of climate change from different non-climate factors, such as land-use change, is challenging. By applying "Liebig's law of the minimum" in a geospatial context, we determined the climate-limited potential for tree, shrub, herbaceous, and non-vegetation fractional cover change for the conterminous United States and compared these potential rates to observed change rates for the period 1986 to 2018. We found that 10% of the land area of the conterminous United States appears to have climate limitations on the change in fractional cover, with a high proportion of these sites located in arid and semiarid ecosystems in the Southwest part of the country. The rates of change in lifeform fractional cover for the remaining area of the country are likely limited by non-climate factors such as the disturbance regime, land management, land-use history, soil conditions, and species interactions and adaptations.

Mindfulness training and exercise differentially impact fear extinction neurocircuitry.

BACKGROUND: The ability to extinguish a maladaptive conditioned fear response is crucial for healthy emotional processing and resiliency to aversive experiences. Therefore, enhancing fear extinction learning has immense potential emotional and health benefits. Mindfulness training enhances both fear conditioning and recall of extinguished fear; however, its effects on fear extinction learning are unknown. Here we investigated the impact of mindfulness training on brain mechanisms associated with fear-extinction learning, compared to an exercise-based program. METHODS: We investigated BOLD activations in response to a previously learned fear-inducing cue during an extinction paradigm, before and after an 8-week mindfulness-based stress reduction program (MBSR, n = 49) or exercise-based stress management education program (n = 27). RESULTS: The groups exhibited similar reductions in stress, but the MBSR group was uniquely associated with enhanced activation of salience network nodes and increased hippocampal engagement. CONCLUSIONS: Our results suggest that mindfulness training increases attention to anticipatory aversive stimuli, which in turn facilitates decreased aversive subjective responses and enhanced reappraisal of the memory.

Diverse learners: learning disabilities and quality of life following mind-body and health education interventions for adults with neurofibromatosis.

PURPOSE: Neurofibromatosis (NF) is associated with low quality-of-life (QoL). Learning disabilities are prevalent among those with NF, further worsening QoL and potentially impacting benefits from mind-body and educational interventions, yet research on this population is scarce. Here, we address this gap by comparing NF patients with and without learning disabilities on QoL at baseline and QoL-related gains following two interventions. METHODS: Secondary analysis of a fully-powered RCT of a mind-body program (Relaxation Response Resiliency Program for NF; 3RP-NF) versus an educational program (Health Enhancement Program for NF; HEP-NF) among 228 adults with NF. Participants reported QoL in four domains (Physical Health, Psychological, Social Relationships, and Environmental). We compare data at baseline, post-treatment, and 12-month follow-up, controlling for intervention type. RESULTS: At baseline, individuals with NF and learning disabilities had lower Psychological (T = -3.0, p = .001) and Environmental (T = -3.8, p < .001) QoL compared to those without learning disabilities. Both programs significantly improved all QoL domains (ps < .0001-0.002) from baseline to post-treatment, regardless of learning disability status. However, those with learning disabilities exceeded the minimal clinically important difference in only one domain (Psychological QoL) compared to three domains in individuals without learning disabilities. Moreover, those with learning disabilities failed to sustain statistically significant gains in Psychological QoL at 12-months, while those without learning disabilities sustained all gains. CONCLUSION: Adults with NF and learning disabilities have lower Psychological and Environmental QoL. While interventions show promise in improving QoL regardless of learning disabilities, additional measures may bolster clinical benefit and sustainability among those with learning disabilities.

Lessons From the Coronavirus Disease Experience: Research Participant and Staff Satisfaction With Remote Cognitive Evaluations.

OBJECTIVE: In New York City in 2020 the pandemic shut down in-person research. Icahn School of Medicine's Alzheimer's Disease Research Center transitioned longitudinal evaluations from in-person to telephone to enhance equity of access. We assessed diverse research participants' and clinical research coordinators' (CRC) satisfaction with remote evaluation and examined sociodemographic, cognitive, and behavioral factors that might impact satisfaction. METHODS: Data collected: 241 participants with Clinical Dementia Rating (CDR) = 0/0.5 (3/2020 to 6/2021). A Telehealth Satisfaction Questionnaire for CRCs and participants was administered at the end of remote evaluations. We compared Telehealth Satisfaction Questionnaire items by CDR and Geriatric Depression Scale. RESULTS: Participants' mean age was 78.4, 61.4% were females, 16.2% were Hispanic, 17.1% Asian, 15.8% were non-Hispanic black, and 72.6% CDR = 0. Participant satisfaction was high [14.1 ± 1.4 (out of 15)] but was lower among those with depression. CRC satisfaction was high [16.9 ± 1.8 (out of 18)] but was lower concerning the ability to explain the test battery and interact with participants with CDR = 0.5. CONCLUSION: Telephone research assessments provide flexibility in a hybrid model. They offer equitable access to research participation for those who do not use computer technology and may promote the retention of diverse elderly research participants.

"I Wish I Had That!": A Qualitative Analysis of Psychosocial Treatment Preferences Among Young Adults With Recent Concussion and Anxiety.

OBJECTIVE: To assess psychosocial treatment preferences and factors that may affect treatment participation among young adults with a recent concussion and co-occurring anxiety. DESIGN: In-depth, semi-structured individual qualitative interviews, followed by thematic analysis using a hybrid deductive-inductive approach. SETTING: Academic medical center in the US Northeast. PARTICIPANTS: Seventeen young adults (18-24y) who sustained a concussion within the past 3-10 weeks and reported at least mild anxiety (≥5 on the Generalized Anxiety Disorder-7 questionnaire). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Primary outcomes include preferences for program content (eg, topics and skills), delivery modality, format, and barriers and facilitators to participation. RESULTS: We identified 4 domains characterizing participants' perceptions of and preferences for treatment. (1) Program content: Participants preferred a program early after injury that included psychoeducation and coping skills (eg, activity pacing, deep breathing, mindfulness). (2) Therapeutic processes: Participants preferred a person-centered approach in which clinicians normalized anxiety postconcussion and reassured them of recovery. (3) Program logistics: Participants endorsed that a brief, virtual program would be acceptable. They preferred access to program components through multiple modalities (eg, audio, video) and accommodations to manage concussion symptoms. (4) Barriers and facilitators to participation: Barriers included acute concussion symptoms (eg, screen sensitivity), time constraints, and forgetting sessions. Facilitators included a program that is flexible (format, scheduling), personalized (self-chosen mode for reminders, measure of accountability), and accessible (ie, advertising through health care professionals or social media). CONCLUSIONS: Participants need psychosocial support that normalizes their experiences and provides education and coping tools. Treatments should be accessible, flexible, and person centered. Psychosocial treatments meeting these preferences may help optimize the recovery of young adults with recent concussion and anxiety.

Anxiety, pain catastrophizing, and pain outcomes among older adults with chronic orofacial pain.

Although chronic orofacial pain (COFP) is common among older adults, the role of psychological factors in pain outcomes among this population has received limited attention. This study examined the role of anxiety and pain catastrophizing, two corelates of pain in other populations, in pain intensity and interference among 166 older adults with COFP (79% female, Mage = 68.84, SD = 5.56). Participants completed an online survey including measures of anxiety, pain catastrophizing, and pain intensity/interference. We applied mediation analyses to test indirect associations between anxiety and pain outcomes via pain catastrophizing. Results indicated that anxiety was positively associated with pain intensity and pain interference (bs = .70-1.12, ps < .05). There was also an indirect association between anxiety and pain interference through pain catastrophizing (b = .35, 95% CI [.0383, .7954]), indicating pain catastrophizing partially accounts for this relationship. Assessing and addressing anxiety and pain catastrophizing has the potential to improve treatment outcomes in this population.

A Meta-Regression of psychosocial factors associated with sleep outcomes in mindfulness-based intervention trials.

OBJECTIVES: In this meta-regression, we aimed to explore associations between changes in psychosocial factors and changes in sleep disturbance during mindfulness-based interventions (MBIs). We also investigated participant-specific and methodological factors associated with sleep disturbance during MBIs. METHOD: We utilized data from a published meta-analysis of 40 randomized controlled trials of MBIs (published from inception to 2020) with a sleep disturbance outcome measure in healthy and clinical adult populations. We conducted meta-regressions to test associations between sleep improvements following MBIs and psychosocial factors, as well as demographic and methodological factors. RESULTS: MBIs were associated with significant reductions in sleep disturbance (SMD = -0.523; 95% CI = -0.678 to -0.368) and psychosocial factors (SMD = -0.213 - -0.894). Reductions in sleep disturbance were associated with reductions in stress (r = 0.74, p = .02) and depression (r = 0.90, p < .001). CONCLUSIONS: MBIs improve sleep disturbance across a wide range of healthy and clinical populations. Stress and depression may be important psychosocial factors associated with sleep disturbance. Future RCTs should include measures of additional factors and should investigate longitudinal associations between psychosocial, demographic, and methodological factors with changes in sleep disturbance to test mechanisms and to identify "active ingredients" of MBIs.

Is there a placental microbiota? A critical review and re-analysis of published placental microbiota datasets.

The existence of a placental microbiota is debated. The human placenta has historically been considered sterile and microbial colonization was associated with adverse pregnancy outcomes. Yet, recent DNA sequencing investigations reported a microbiota in typical human term placentas. However, this detected microbiota could represent background DNA or delivery-associated contamination. Using fifteen publicly available 16S rRNA gene datasets, existing data were uniformly re-analyzed with DADA2 to maximize comparability. While Amplicon Sequence Variants (ASVs) identified as Lactobacillus, a typical vaginal bacterium, were highly abundant and prevalent across studies, this prevalence disappeared after applying likely  DNA contaminant removal to placentas from term cesarean deliveries. A six-study sub-analysis targeting the 16S rRNA gene V4 hypervariable region demonstrated that bacterial profiles of placental samples and technical controls share principal bacterial ASVs and that placental samples clustered primarily by study origin and mode of delivery. Contemporary DNA-based evidence does not support the existence of a placental microbiota.ImportanceEarly-gestational microbial influences on human development are unclear. By applying DNA sequencing technologies to placental tissue, bacterial DNA signals were observed, leading some to conclude that a live bacterial placental microbiome exists in typical term pregnancy. However, the low-biomass nature of the proposed microbiome and high sensitivity of current DNA sequencing technologies indicate that the signal may alternatively derive from environmental or delivery-associated bacterial DNA contamination. Here we address these alternatives with a re-analysis of 16S rRNA gene sequencing data from 15 publicly available placental datasets. After identical DADA2 pipeline processing of the raw data, subanalyses were performed to control for mode of delivery and environmental DNA contamination. Both environment and mode of delivery profoundly influenced the bacterial DNA signal from term-delivered placentas. Aside from these contamination-associated signals, consistency was lacking across studies. Thus, placentas delivered at term are unlikely to be the original source of observed bacterial DNA signals.

The impact of a virtual mind-body program on resilience factors among international English-speaking adults with neurofibromatoses: secondary analysis of a randomized clinical trial.

PURPOSE: To test the effects of the Relaxation Response Resiliency Program - Neurofibromatosis (3RP-NF), a mind-body resilience program for people with NF, on resilience factors from baseline to post-treatment and 6- and 12-month follow-up. METHODS: This is a secondary analysis of a fully powered randomized clinical trial (RCT) of 3RP-NF and health education control (HEP-NF). We recruited adults with NF1, NF2, or schwannomatosis who reported stress or difficulty coping with NF symptoms. Both conditions received 8 weekly 90-minute group sessions; 3RP-NF focused on building resilience skills. We measured resilience factors via the Measure of Current Status-A (adaptive coping), Cognitive and Affective Mindfulness Scale-Revised (mindfulness), Gratitude Questionnaire-6 (gratitude), Life Orientation Test Optimism Scale (optimism), and Medical Outcomes Study Social Support Survey (perceived social support) at baseline, post-intervention, and 6- and 12-month follow-up. We used linear mixed models with completely unstructured covariance across up to four repeated measurements (baseline, post-treatment, and 6- and 12-month follow-up) to investigate treatment effects on resilience factors. RESULTS: We enrolled 228 individuals (Mage=42.7, SD = 14.6; 74.5% female; 87.7% White; 72.8% NF1, 14.0% NF2, 13.2% schwannomatosis). Within groups, both 3RP-NF and HEP-NF showed statistically significant improvements in all outcomes across timepoints. 3RP-NF showed significantly greater improvement in adaptive coping compared to HEP-NF from baseline to post-intervention and baseline to 6 months (Mdifference= 0.29; 95% CI 0.13-0.46; p < 0.001; Mdifference= 0.25; 95% CI 0.07-0.33; p = 0.005); there were no other between-group differences amongst the remaining resilience factors. CONCLUSION: 3RP-NF showed promise in sustainably improving coping abilities amongst people with NF. TRIAL REGISTRATION INFORMATION: ClinicalTrials.gov Identifier: NCT03406208. Registration submitted December 6, 2017, first patient enrolled October 2017.

How Do Orthopaedic Providers Conceptualize Good Patient Outcomes and Their Barriers and Facilitators After Acute Injury? A Qualitative Study.

BACKGROUND: Good clinical outcomes in orthopaedics are largely dictated by the biomedical model, despite mounting evidence of the role of psychosocial factors. Understanding orthopaedic providers' conceptualizations of good clinical outcomes and what facilitates and hinders them may highlight critical barriers and opportunities for training providers on biopsychosocial models of care and integrating them into practice. QUESTIONS/PURPOSES: (1) How do orthopaedic trauma healthcare providers define good clinical outcomes for their patients after an acute orthopaedic injury? (2) What do providers perceive as barriers to good outcomes? (3) What do providers perceive as facilitators of good outcomes? For each question, we explored providers' responses in a biopsychosocial framework. METHODS: In this cross-sectional, qualitative study, we recruited 94 orthopaedic providers via an electronic screening survey from three Level I trauma centers in geographically diverse regions of the United States (rural southeastern, urban southwestern, and urban northeastern). This study was part of the first phase of a multisite trial testing the implementation of a behavioral intervention to prevent chronic pain after acute orthopaedic injury. Of the 94 participants who were recruited, 88 completed the screening questionnaire. Of the 88 who completed it, nine could not participate because of scheduling conflicts. Thus, the final sample included 79 participants: 48 surgeons (20 attendings, 28 residents; 6% [three of 48] were women, 94% [45 of 48] were between 25 and 55 years old, 73% [35 of 48] were White, and 2% [one of 48] were Hispanic) and 31 other orthopaedic professionals (10 nurse practitioners, registered nurses, and physician assistants; 13 medical assistants; five physical therapists and social workers; and three research fellows; 68% [21 of 31] were women, 97% [30 of 31] were between 25 and 55 years old, 71% [22 of 31] were White, and 39% [12 of 31] were Hispanic). Using a semistructured interview, our team of psychology researchers conducted focus groups, organized by provider type at each site, followed by individual exit interviews (5- to 10-minute debriefing conversations and opportunities to voice additional opinions one-on-one with a focus group facilitator). In each focus group, providers were asked to share their perceptions of what constitutes a "good outcome for your patients," what factors facilitate these outcomes, and what factors are barriers to achieving those outcomes. Focus groups were approximately 60 minutes long. A research assistant recorded field notes during the focus groups to summarize insights gained and disseminate findings to the broader research team. Using this procedure, we determined that thematic saturation was reached for all topics and no additional focus groups were necessary. Three independent coders identified the codes of good outcomes, outcome barriers, and outcome facilitators and applied this coding framework to all transcripts. Three separate data interpreters collaboratively extracted themes related to biomedical, psychological, and social factors and corresponding inductive subthemes. RESULTS: Although orthopaedic providers' definitions of good outcomes naturally included biomedical factors (bone healing, functional independence, and pain alleviation), they were also marked by nuanced psychosocial factors, including the need for patients to recover from psychological trauma associated with injury and feel heard and understood-not just as outcome facilitators, but also as key outcomes themselves. Regarding perceived barriers to good outcomes, providers interwove psychological and biomedical factors (for example, "if they're a smoker, if they have depression, anxiety…") and discussed how psychological dysfunction (for example, maladaptive avoidance or fear of reinjury) can limit key behaviors during recovery (such as adherence to physical therapy regimens). Unprimed, providers also cited resiliency-related terms from psychological research, including (low) "self-efficacy," "catastrophic thinking," and (lack of) psychological "hardiness" as barriers. Regarding perceived facilitators of good outcomes, various social and socioeconomic factors emerged, including a biosocial connection between recovery, social support, and "privilege" (such as occupation or education). These perspectives emerged across sites and provider types. CONCLUSION: Although the biomedical model prevails in clinical practice, providers across all sites, in various roles, defined good outcomes and their barriers and facilitators in terms of interconnected biopsychosocial factors without direct priming to do so. Thus, similar Level I trauma centers may be more ready to adopt biopsychosocial care approaches than initially expected. CLINICAL RELEVANCE: Providers' perspectives in this study aligned with a growing body of research on the role of biomedical and psychosocial factors in surgical outcomes and risk of transition to chronic pain. To translate these affirming attitudes into practice, other Level I trauma centers could encourage leaders who adopt biopsychosocial approaches to share their perspectives and train other providers in biopsychosocial conceptualization and treatment.

"Alone in the dark": A qualitative study of treatment experiences among young adults with a recent concussion and anxiety.

PURPOSE: Young adults with anxiety are vulnerable to developing persistent symptoms following concussions. In order to develop psychosocial interventions to prevent persistent post-concussion symptoms, we need to understand patients' 1) experiences with treatments offered by health care providers; 2) experiences with attempted concussion management strategies; and 3) needs after their injury. METHODS: We conducted in-depth interviews with 17 young adults with recent (≤ 10 weeks) concussions who have at least mild anxiety (Generalized Anxiety Disorder Assessment-7 ≥ 5). We used a hybrid deductive-inductive approach to thematic analysis. RESULTS: Findings provide insight into recommended treatments (e.g., active/avoidant strategies, accommodations, referrals), attempted strategies (e.g., lifestyle changes, pacing, relationships, acceptance-based coping skills), and patient needs (e.g., education, accommodations, referrals for cognitive and emotional skills). Participants frequently expressed that treatment recommendations were confusing and difficult to implement. They initiated non-prescribed strategies that helped promote recovery and expressed a desire for more interdisciplinary treatment and education on concussions. CONCLUSION: Patients' perceptions of health care provider recommendations after concussions did not fully meet patients' perceived needs. Young adults with concussions and anxiety would benefit from more education, guidance, and psychosocial and rehabilitation services. Addressing these gaps may help align treatments with patients' needs and therefore help optimize their recovery.

The use of subjective cognitive complaints for detecting mild cognitive impairment in older adults across cultural and linguistic groups: A comparison of the Cognitive Function Instrument to the Montreal Cognitive Assessment.

INTRODUCTION: This pilot study aims to explore the psychometric properties of the Cognitive Function Instrument (CFI) as a measure of subjective cognitive complaints (SCC) and its performance in distinguishing mild cognitive impairment (MCI) from normal control (NC) compared to an objective cognitive screen (Montreal Cognitive Assessment [MoCA]). METHODS: One hundred ninety-four community-dwelling non-demented older adults with racial/ethnic diversity were included. Unidimensionality and internal consistency of the CFI were examined using factor analysis, Cronbach's alpha, and McDonald's omega. Logistic regression models and receiver operating characteristic (ROC) analysis were used to examine the performance of CFI. RESULTS: The CFI demonstrated adequate internal consistency; however, the fit for a unidimensional model was suboptimal. The CFI distinguished MCI from NC alone or in combination with MoCA. ROC analysis showed comparable performance of the CFI and the MoCA. DISCUSSION: Our findings support the use of CFI as a brief and easy-to-use screen to detect MCI in culturally/linguistically diverse older adults. HIGHLIGHT: What is the key scientific question or problem of central interest of the paper? Subjective cognitive complaints (SCCs) are considered the earliest sign of dementia in older adults. However, it is unclear if SCC are equivalent in different cultures. The Cognitive Function Instrument (CFI) is a 14-item measure of SCC. This study provides pilot data suggesting that CFI is sensitive for detecting mild cognitive impairment in a cohort of older adults with racial/ethnic diversity. Comparing performance, CFI demonstrates comparable sensitivity to the Montreal Cognitive Assessment, an objective cognitive screening test. Overall, SCC may provide a non-invasive, easy-to-use method to flag possible cognitive impairment in both research and clinical settings.

The immunobiology of preterm labor and birth: intra-amniotic inflammation or breakdown of maternal-fetal homeostasis.

In brief: The syndrome of preterm labor comprises multiple established and novel etiologies. This review summarizes the distinct immune mechanisms implicated in preterm labor and birth and highlights potential strategies for its prevention. Abstract: Preterm birth, the leading cause of neonatal morbidity and mortality worldwide, results from preterm labor, a syndrome that includes multiple etiologies. In this review, we have summarized the immune mechanisms implicated in intra-amniotic inflammation, the best-characterized cause of preterm labor and birth, as well as novel etiologies non-associated with intra-amniotic inflammation (i.e. formally known as idiopathic). While the intra-amniotic inflammatory responses driven by microbes (infection) or alarmins (sterile) have some overlap in the participating cellular and molecular processes, the distinct natures of these two conditions necessitate the implementation of specific approaches to prevent adverse pregnancy and neonatal outcomes. Intra-amniotic infection can be treated with the correct antibiotics, whereas sterile intra-amniotic inflammation could potentially be treated by administering a combination of anti-inflammatory drugs (e.g. betamethasone, inflammasome inhibitors, etc.). Recent evidence also supports the role of fetal T-cell activation as a newly described trigger for preterm labor and birth in a subset of cases diagnosed as idiopathic. Moreover, herein we also provide evidence of two maternally-driven immune mechanisms responsible for preterm births formerly considered to be idiopathic. First, the impairment of maternal Tregs can lead to preterm birth, likely due to the loss of immunosuppressive activity resulting in unleashed effector T-cell responses. Secondly, homeostatic macrophages were shown to be essential for maintaining pregnancy and promoting fetal development, and the adoptive transfer of homeostatic M2-polarized macrophages shows great promise for preventing inflammation-induced preterm birth. Collectively, in this review, we discuss the established and novel immune mechanisms responsible for preterm birth and highlight the potential targets for novel strategies aimed at preventing the multi-etiological syndrome of preterm labor leading to preterm birth.

Mindfulness is inversely associated with psychological symptoms in long-term cardiac arrest survivors.

Identifying correlates of psychological symptoms in cardiac arrest (CA) survivors is a major research priority. In this longitudinal survey study, we evaluated associations between mindfulness, baseline psychological symptoms, and 1-year psychological symptoms in long-term CA survivors. We collected demographic and CA characteristics at baseline. At both timepoints, we assessed posttraumatic stress symptoms (PTS) through the PTSD Checklist-5 (PCL-5) and depression and anxiety symptoms through the Patient Health Questionnaire-4 (PHQ-4). At follow-up, we assessed mindfulness through the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R). We used adjusted linear regression to predict 1-year PCL-5 and PHQ-4 scores, with particular consideration of the CAMS-R as a cross-sectional correlate of outcome. We included 129 CA survivors (mean age: 52 years, 52% male, 98% white). At 1-year follow-up, in adjusted models, CAMS-R (ß: -0.35, p < 0.001) and baseline PCL-5 scores (ß: 0.56, p < 0.001) were associated with 1-year PCL-5 scores. CAMS-R (ß: -0.34, p < 0.001) and baseline PHQ-4 scores were associated with 1-year PHQ-4 scores (ß: 0.37, p < 0.001). In conclusion, mindfulness was inversely associated with psychological symptoms in long-term CA survivors. Future studies should examine the longitudinal relationship of mindfulness and psychological symptoms after CA.

"Hidden gains"? Measuring the impact of mindfulness-based interventions for people with mild traumatic brain injury: a scoping review.

BACKGROUND: Mindfulness-based interventions can support recovery from mild traumatic brain injury (mTBI). Although measurement is a key determinant of outcomes, there is no comprehensive assessment of measurement approaches used to capture outcomes of these programs. Here, we review the domains targeted, measurement techniques used, and domains and techniques most affected by mindfulness-based interventions for mTBI. METHODS: We conducted a scoping review. After screening and full-text review, we included 29 articles and extracted data related to measurement domains, techniques, and results. RESULTS: We identified 8 outcome domains, each with multiple subdomains. The most common domains were cognitive symptoms and general health/quality of life. No quantitative studies directly assessed sleep, physical-function, or pain-catastrophizing. Self-report was the most common measurement technique, followed by performance-based methods. Coping, somatic symptoms, emotional symptoms, stress response, and domains of cognition (particularly attention) were the most frequently improved domains. Qualitative results described benefits across all domains and suggested novel areas of benefit. Biomarkers did not reflect significant change. CONCLUSIONS: Mindfulness-based interventions for mTBI impact a range of clinical domains and are best captured with a combination of measurement approaches. Using qualitative methods and expanding the breadth of outcomes may help capture underexplored effects of mindfulness-based interventions for mTBI.

My Healthy Brain: a multimodal lifestyle program to promote brain health.

BACKGROUND: Promoting brain health depends on sustaining healthy behaviors across the lifespan. Yet, public adoption of lifestyle behaviors and knowledge of cognitive decline (CD) prevention remains poor. Our multidisciplinary team developed My Healthy Brain (MHB) to promote a healthy lifestyle (e.g. diet, exercise, alcohol, sleep) and build cognitive reserve (e.g. memory compensatory strategies). Our objective was to demonstrate early proof-of-concept for MHB by exploring the feasibility, acceptability, and improvement in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective wellbeing. MATERIALS AND METHODS: Older adults with subjective (self-report only) or objective (confirmed by cognitive testing) CD, referred by neurologists to modify lifestyle risk factors (e.g. sedentary), participated in a non-randomized open pilot of MHB (N = 24). Participants completed the 8-week MHB group (90 min each) and pre-post outcome measures. RESULTS: MHB met all a-priori set benchmarks, including good feasibility of recruitment (71% of patients screened) and enrollment (75% completed baseline), and good acceptability of treatment (75% completed 6 of 8 sessions and post-testing). Program satisfaction was excellent (100% of participants) and no adverse events were reported. We also observed improvements in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective well-being. DISCUSSION: While MHB demonstrated preliminary feasibility and the potential to modify lifestyle risk factors for CD, the program can be improved. Future work will explore the integration of mindfulness skills with behavioral principles to bolster multidomain lifestyle change, and the live video delivery format to bypass barriers to participation.

Depression explains the association between pain intensity and pain interference among adults with neurofibromatosis.

INTRODUCTION: Neurofibromatoses (NFs; NF1, NF2 and Schwannomatosis) are incurable genetic syndromes characterized by nerve sheath tumors and often accompanied by substantial emotional distress (e.g., depression and anxiety). Pain is also common but understudied in adults with NF and interferes with daily living. In other medical populations, depression and anxiety have a strong association with pain interference. However, research has not explored the relationship of depression and anxiety to pain interference among adults with NF experiencing pain. The aim of this study was to test the hypothesis that depression and anxiety will mediate the association between pain intensity and pain interference among geographically diverse adults with NF who endorse pain. METHODS: We used baseline data from an RCT of a mind-body intervention aimed at improving quality of life in adults with NF. Participants (N = 214) who endorsed pain completed measures of demographics, clinical characteristics, baseline pain intensity, pain interference, depression, and anxiety. We constructed a multiple mediation model in R using the lavaan package to test our hypothesis. RESULTS: Preliminary analyses showed differences in pain interference by NF diagnostic subtype (F(2, 206) = 6.82, p = 001). In a model that controlled for NF diagnostic subtype, we found that depression (ß = .07, p = .017), but not anxiety (ß = -.003, p = .878), partially mediated the association between pain intensity and pain interference. CONCLUSION: Improving depression has the potential to decrease pain interference among people with NF who experience pain. TRIAL REGISTRATION: Clinicaltrials.gov Registration #: NCT03406208.

Sustainability of Improvements in Adaptive Coping Following Mind-Body and Activity Training for Chronic Pain.

BACKGROUND: The strategies patients use to cope with chronic pain are key determinants of pain-related treatment outcomes and are often targeted in psychosocial interventions for chronic pain. However, improvements in coping often fade after intervention completion. Here, we test whether previously reported improvements in coping following two novel mind-body and activity interventions are maintained 3 months after completion. METHODS: Eighty-two patients with heterogeneous chronic pain were randomized to two identical mind-body and activity interventions, one with the addition of a Fitbit device (GetActive-Fitbit) and one without it (GetActive; n = 41 each). Participants completed measures of pain-catastrophizing, kinesiophobia, mindfulness, adaptive coping, and pain-resilience at baseline, post-intervention, and at 3-month follow-up. RESULTS: At follow-up, participants in both groups exhibited sustained improvements in all five coping measures compared to baseline (significant in both groups for all measures except for p = .05 in kinesiophobia in GetActive and p = .07 in pain resilience in GetActive-Fitbit). CONCLUSIONS: Overall, GetActive and GetcActive-Fitbit are promising interventions to sustainably improve coping with chronic pain. TRIAL REGISTRATION: This trial is registered under ClinicalTrials.gov identifier NCT03412916.

Smartphone ownership and usage in Chinese- and English-speaking older adults.

BACKGROUND: Data collection by smartphone is becoming more widespread in healthcare research. Previous studies reported racial/ethnical differences in the use of digital health technology. However, cross-language group comparison (Chinese- and English-speaking older adults) were not performed in these studies. This project will expand to smartphone technology use in diverse older populations with a focus on Chinese American older adults who are monolingual Chinese-speakers. METHOD: The Alzheimer's Disease Research Center (ADRC) at Icahn School of Medicine at Mount Sinai (ISMMS) evaluates diverse older populations using National Alzheimer's Coordinating Center's Uniform Data Set (NACC UDS). The UDS has different language versions, including English and Chinese. The evaluation includes a medical examination, cognitive assessments, and a research blood draw. Smartphone ownership and usage were captured using a local questionnaire developed by our ADRC. The questionnaire, available in English and Chinese, was administered by our ADRC coordinators during the COVID-19 pandemic. Multivariate analysis of variance (MANOVA) was used to examine differences in technology ownership and usages between the two language groups, while controlling for age, gender, education, and cognitive status (measured by Clinical Dementia Rating). RESULT: 33 Chinese- and 117 English-speaking older adults who received a diagnosis of normal cognition or mild cognitive impairment at consensus were included in the data analysis. Results reveal a high prevalence of smartphone ownership in our Chinese- (100%) and English-speaking older participants (86.3%). Participants in both language groups use mobile technology for a wide range of purposes, such as getting news and other information (Chinese=90.9%; English=87.2%), sending/receiving text (Chinese=97.0%; English=96.6%), watching videos/TV shows (Chinese=78.8%; English=69.2%), and taking classes (Chinese=57.5%; English=57.3%). However, Chinese-speaking older adults were less likely than English-speaking older adults to use mobile technology to post their own reviews or comments online (Chinese=9.1%; English=39.3%, p=0.001), download or purchase an app (Chinese=21.2%; English=70.9%, p<0.001), track health/ fitness via apps/website (Chinese=12.1%; English=47.9%, p<0.001) and manage/receive medical care (Chinese=15.2%; English=67.5%, p<0.001). CONCLUSION: Our findings highlight potential barriers to smartphone usage in Chinese American older adults with limited English proficiency. The results have implications for how smartphone technology can be used in clinical practice and aging research.

Getting Active Mindfully: Rationale and Case Illustration of a Group Mind-body and Activity Program for Chronic Pain.

Chronic pain is associated with substantial decreases in physical and emotional health. Psychosocial and physical restoration interventions, although potentially helpful, typically show small-to-moderate improvements that are limited to the short term, and often exhibit problematic adherence. Here, we present GetActive-Fitbit, a novel 10-week group program that integrates mind-body skills, pain coping and gradual increases in activity reinforced by a commercially available digital monitoring device (Fitbit). We illustrate the program among a group of 4 adults with heterogeneous chronic pain. We also highlight pre to post-program improvements in physical function (objective, performance-based and self-report), emotional function (depression and anxiety) and other relevant outcomes targeted by the program (e.g., pain intensity, catastrophizing, mindfulness, coping, kinesiophobia, emotional support, social isolation, pain resilience, program satisfaction and impression of change). Group participants' experiences suggest that GetActive-Fitbit is credible, useful, and shows potential to improve physical and emotional function among this challenging population.Clinical trial number: NCT03412916.
