Leveraging Cross-Campus Expertise to Contribute to Dementia Care Through Music.

While there is evidence of the benefits of music for health and wellness, current US clinical practice does not commonly incorporate arts-based interventions, one drawback of which appears to be limited communication among practitioners within the arts, sciences, and health professions fields. This article shares a story of a 2-year multidisciplinary music in medicine program that aims to inspire joy and connection among people with dementia through interactive, creative musical experiences. The authors discuss the program from conception to pilot, canvass adaptations made to adhere to COVID-19 protocols, illuminate common themes of flexibility and curiosity, and share cross-campus, multidisciplinary collaboration experiences that guided the work.

Behavioral Interventions in Mild Cognitive Impairment (MCI): Lessons from a Multicomponent Program.

Comparative effectiveness of behavioral interventions to mitigate the impacts of degeneration-based cognitive decline is not well understood. To better address this gap, we summarize the studies from the Healthy Action to Benefit Independence & Thinking (HABIT®) program, developed for persons with mild cognitive impairment (pwMCI) and their partners. HABIT® includes memory compensation training, computerized cognitive training (CCT), yoga, patient and partner support groups, and wellness education. Studies cited include (i) a survey of clinical program completers to establish outcome priorities; (ii) a five-arm, multi-site cluster randomized, comparative effectiveness trial; (iii) and a three-arm ancillary study. PwMCI quality of life (QoL) was considered a high-priority outcome. Across datasets, findings suggest that quality of life was most affected in groups where wellness education was included and CCT withheld. Wellness education also had greater impact on mood than CCT. Yoga had a greater impact on memory-dependent functional status than support groups. Yoga was associated with better functional status and improved caregiver burden relative to wellness education. CCT had the greatest impact on cognition compared to yoga. Taken together, comparisons of groups of program components suggest that knowledge-based interventions like wellness education benefit patient well-being (e.g., QoL and mood). Skill-based interventions like yoga and memory compensation training aid the maintenance of functional status. Notably, better adherence produced better outcomes. Future personalized intervention approaches for pwMCI may include different combinations of behavioral strategies selected to optimize outcomes prioritized by patient values and preferences.

Latent Factor Structure of Outcome Measures Used in the HABIT® Mild Cognitive Impairment Intervention Programs.

BACKGROUND: In Alzheimer's disease and related disorders (ADRD) research, common outcome measures include cognitive and functional impairment, as well as persons with mild cognitive impairment (pwMCI) and care partner self-reported mood and quality of life. Studies commonly analyze these measures separately, which potentially leads to issues of multiple comparisons and/or multicollinearity among measures while ignoring the latent constructs they may be measuring. OBJECTIVE: This study sought to examine the latent factor structure of a battery of 12-13 measures of domains mentioned above, used in a multicomponent behavioral intervention (The HABIT® program) for pwMCI and their partners. METHODS: Exploratory factor analysis (EFA) involved 214 pwMCI-partner pairs. Subsequent Confirmatory factor analyses (CFA) used 730 pairs in both pre- and post-intervention conditions. RESULTS: EFA generated a three-factor model. Factors could be characterized as partner adjustment (29.9%), pwMCI adjustment (18.1%), and pwMCI impairment (12.8%). The subsequent CFA confirmed our findings, and the goodness-of-fit for this model was adequate in both the pre- (CFI = 0.937; RMSEA = 0.057, p = 0.089) and post-intervention (CFI = 0.942; RMSEA = 0.051, p = 0.430) groups. CONCLUSION: Results demonstrated a stable factor structure across cohorts and intervention conditions suggesting that three broad factors may provide a straightforward and meaningful model to assess intervention outcome, at least during the MCI phase of ADRD.

Computerized Cognitive Training (CCT) versus Yoga Impact on 12 Month Post Intervention Cognitive Outcome in Individuals with Mild Cognitive Impairment.

There is currently limited and mixed evidence for the cognitive benefits of Computerized Cognitive Training (CCT) and yoga in persons with Mild Cognitive Impairment (pwMCI). The objective of this study was to investigate the benefit of computerized cognitive training (CCT) vs. physical (yoga) intervention on cognitive abilities. Participants in this study were part of the larger Mayo Clinic's Healthy Action to Benefit Independence and Thinking (HABIT) program comparative effectiveness trial. The HABIT program is designed for pwMCI and their care partner and consists of five behavioral interventions: CCT, Memory Support System-Calendar (MSS-Calendar), wellness education, support groups, and yoga. The subtractive study design randomly withheld one of the interventions for a total of five study arms. Longitudinal mixed-effects regression models were used to investigate the hypothesis that CCT and yoga has a greater positive impact on psychomotor and basic attention abilities at 12 months post-intervention as compared to the other HABIT interventions. Findings showed CCT had a positive impact compared to yoga on the Cogstate psychomotor/attention composite at 12 months post-intervention (ES = 0.54; unadjusted p value = 0.007, adjusted p value = 0.021). The impact of yoga or combining CCT with yoga did not show statistically significant improvement. Continued CCT practice at home showed further benefit on psychomotor/attention at 12 months post-intervention. There was no significant benefit of CCT or yoga on Cogstate learning/working memory composite.

Comparative Effects of Physical Exercise and Other Behavioral Interventions on Functional Status Outcomes in Mild Cognitive Impairment.

OBJECTIVES: Lifestyle modifications for those with mild cognitive impairment (MCI) may promote functional stability, lesson disease severity, and improve well-being outcomes such as quality of life. The current analysis of our larger comparative effectiveness study evaluated which specific combinations of lifestyle modifications offered as part of the Mayo Clinic Healthy Action to Benefit Independence in Thinking (HABIT) program contributed to the least functional decline in people with MCI (pwMCI) over 18 months. METHODS: We undertook to compare evidence-based interventions with one another rather than to a no-treatment control group. The interventions were five behavioral treatments: computerized cognitive training (CCT), yoga, Memory Support System (MSS) training, peer support group (SG), and wellness education (WE), each delivered to both pwMCI and care partners, in a group-based program. To compare interventions, we randomly withheld one of the five HABIT® interventions in each of the group sessions. We conducted 24 group sessions with between 8 and 20 pwMCI-partner dyads in a session. RESULTS: Withholding yoga led to the greatest declines in functional ability as measured by the Functional Activities Questionnaire and Clinical Dementia Rating. In addition, memory compensation (calendar) training and cognitive exercise appeared to have associations (moderate effect sizes) with better functional outcomes. Withholding SG or WE appeared to have little effect on functioning at 18 months. CONCLUSIONS: Overall, these results add to the growing literature that physical exercise can play a significant and lasting role in modifying outcomes in a host of medical conditions, including neurodegenerative diseases.

Changes in description naming for common and proper nouns after left anterior temporal lobectomy.

Numerous studies have shown that surgical resection of the left anterior temporal lobe (ATL) is associated with a decline in object naming ability (Hermann et al., 1999). In contrast, few studies have examined the effects of left ATL surgery on auditory description naming (ADN) or category-specific naming. Compared with object naming, which loads heavily on visual recognition processes, ADN provides a more specific measure of concept retrieval. The present study examined ADN declines in a large group of patients who were tested before and after left ATL surgery, using a 2 × 2 × 2 factorial manipulation of uniqueness (common vs. proper nouns), taxonomic category (living vs. nonliving things), and time (pre- vs. postsurgery). Significant declines occurred across all categories but were substantially larger for proper living (PL) concepts, i.e., famous individuals. The disproportionate decline in PL noun naming relative to other conditions is consistent with the notion that the left ATL is specialized not only for retrieval of unique entity concepts, but also plays a role in processing social concepts and person-specific features.

Assessing Cognitive Functioning in People Living With HIV (PLWH): Factor Analytic Results From CHARTER and NNTC Cohorts.

BACKGROUND: Single summary scores, such as the Global Deficit Score, are often used to classify overall performance on neuropsychological batteries. The factor structure of test scores that underlie Global Deficit Score in studies of people living with HIV (PLWH) was assessed to determine whether individual test scores loaded onto a unitary factor to summarize performance. SETTING: Secondary data analysis on baseline data of PLWH from National NeuroAIDS Tissue Consortium and CNS HIV Antiretroviral Therapy Effects Research (CHARTER) Study. METHOD: Primary analyses included testing model structure and fit of neuropsychological test scores with confirmatory and exploratory factor analyses. Secondary analyses involved receiver operating characteristic curves, and associations with psychosocial and medical variables. RESULTS: Participants with confounds were excluded, leading to 798 (National NeuroAIDS Tissue Consortium) and 1222 (CHARTER) cases. When confirmatory factor analysis models were structured to be consistent with theoretically-based cognitive domains, models did not fit adequately. Per exploratory factor analyses, tests assessing speeded information processing, working memory, and executive functions loaded onto a single factor and explained the most variance in both cohorts. This factor tended to be associated with age, estimated premorbid ability, and aspects of substance use history. Its relation to age, in context of demographically corrected neuropsychological scores, suggested accelerated aging. CONCLUSION: Results indicate that individual neuropsychological tests did not load exactly onto expected domains, suggesting another framework for future analyses of cognitive domains. The possibility of a new index, and its use to assess cognitive impairment in PLWH, is suggested for further diagnostic and prognostic purposes.

Functional ability is associated with higher adherence to behavioral interventions in mild cognitive impairment.

Objective: Behavioral interventions during early memory decline hold promise in delaying the development of dementia. In the present study, participants in a multimodal behavioral intervention study were assessed for post-intervention adherence and predictors of adherence.Methods: Participants (N = 272, mean age = 75.04 ± 7.54) diagnosed with amnestic Mild Cognitive Impairment (aMCI) were assigned to intervention groups receiving four out of five behavioral intervention components, including yoga, memory compensation training, computerized cognitive training, support groups, and/or wellness education. Length of the intervention was 10 days, 4 h per day, with post-intervention follow-up at 6, 12, and 18 months.Results: Two-hundred and thirty-seven participants completed the 6-month post-intervention follow-up measures, 228 participants completed the 12-month measures, and 218 participants completed the 18-month measures. Participants fully adhered to a mean of 2 out of the 4 taught intervention components. Eighty-nine percent of participants were at least partially adherent to one or more taught intervention components at 6-, 12-, and 18-month post-intervention follow-up. Physical activity was the most adhered to intervention while group support was the least adhered to intervention across all three follow-up time-points. Higher educational level, higher baseline depressive symptoms, higher baseline global cognitive functioning, and better baseline and concurrent functional abilities were associated post-intervention adherence.Conclusion: Changes in functional abilities are associated with disease progression among persons with aMCI. In the present study, individuals with aMCI who have higher education, higher depressive symptoms, and better baseline functioning abilities are more likely to adhere to behavioral intervention components over time. Post-intervention adherence also associates with concurrent daily function.

Comparative Effectiveness of Behavioral Interventions on Quality of Life for Older Adults With Mild Cognitive Impairment: A Randomized Clinical Trial.

Importance: Recommendations to engage in behavioral strategies to combat clinically significant cognitive and behavioral symptoms are routinely given to persons with mild cognitive impairment (MCI). The comparative effectiveness of these behavioral interventions is not well understood. Objective: To compare the incremental effects of combinations of 5 behavioral interventions on outcomes of highest importance to patients with MCI. Design, Setting, and Participants: In this multisite, cluster randomized, multicomponent comparative effectiveness trial, 272 patients from 4 academic medical outpatient centers (Mayo Clinic, Rochester, Minnesota; Mayo Clinic, Scottsdale, Arizona; Mayo Clinic, Jacksonville, Florida; and University of Washington, Seattle) were recruited from September 1, 2014, to August 31, 2016, with last follow-up March 31, 2019. All participants met the National Institute on Aging-Alzheimer's Association criteria for MCI. Interventions: The intervention program was modeled on the Mayo Clinic Healthy Action to Benefit Independence and Thinking (HABIT) program, a 50-hour group intervention conducted during 2 weeks, including memory compensation training, computerized cognitive training, yoga, patient and partner support groups, and wellness education. In our study, 1 of 5 interventions was randomly selected to be withheld for each intervention group. Participants and their partners had 1-day booster sessions at 6 and 12 months after intervention. Main Outcomes and Measures: Quality-of-life measurement of participants with MCI at 12 months was the primary outcome, selected based on the preference rankings of previous program participants. Mood, self-efficacy, and memory-based activities of daily living were also highly ranked. Results: A total of 272 participants (mean [SD] age, 75 [8] years; 160 [58.8%] male and 112 [41.2%] female) were enrolled in this study, with 56 randomized to the no yoga group, 54 to no computerized cognitive training, 52 to no wellness, 53 to no support, and 57 to no memory support system. The greatest effect size for quality of life was between the no computerized cognitive training and no wellness education groups at 0.34 (95% CI, 0.05-0.64). In secondary analyses, wellness education had a greater effect on mood than computerized cognitive training (effect size, 0.53; 95% CI, 0.21-0.86), and yoga had a greater effect on memory-related activities of daily living than support groups (effect size, 0.43; 95% CI, 0.13-0.72). Conclusions and Relevance: These results provide further support for behavioral interventions for persons with MCI. Different outcomes were optimized by different combinations of interventions. These findings provide an initial exploration of the effect of behavioral interventions on patient-advocated outcomes in persons with MCI.

Self-Efficacy Mediates the Association Between Physical Function and Perceived Quality of Life in Individuals with Mild Cognitive Impairment.

BACKGROUND: Research has shown that individuals with mild cognitive impairment (MCI) value quality of life (QoL) above and beyond cognitive function or other potential outcomes in MCI. There is evidence supporting the negative impact of poor physical function on QoL ratings. OBJECTIVE: The study explored whether a modified measure of self-efficacy for managing MCI and education mediated and/or moderated the relationship between physical function and QoL in persons with MCI. METHODS: Baseline data from 200 participants with MCI were obtained from a larger study assessing the effectiveness of a behavioral intervention. Physical function was assessed by the Short Physical Performance Battery. QoL was assessed with the Quality of Life in Alzheimer's Disease scale. Memory-related self-efficacy was assessed using a modified 9-item version of the Chronic Disease Self-Efficacy Scales. Mediation and moderation analyses tested the hypotheses that self-efficacy and education alter the association between physical function and QoL in individuals with MCI. All analyses were adjusted for age, cognitive severity, and sex. RESULTS: Self-efficacy for managing MCI was a significant mediator of the association between physical function and perceived QoL. Individuals with better physical function reported higher self-efficacy which was associated with higher QoL ratings. CONCLUSIONS: Greater self-efficacy for managing MCI mediated the negative association between physical function and quality of life in this exploratory study. Interventions aimed at enhancing memory self-efficacy in MCI may improve perceived QoL, even in the presence of poor physical function. Future research is needed to investigate this further.

Behavioral Interventions to Prevent or Delay Dementia: Protocol for a Randomized Comparative Effectiveness Study.

BACKGROUND: Currently, people at risk for dementia and their caregivers are confronted with confusing choices about what behavioral interventions are most effective. OBJECTIVE: The objective of this study is to determine which empirically supported behavioral interventions most impact the outcomes highly valued by patients with mild cognitive impairment and their partners. METHODS: This protocol describes a comparative effectiveness trial targeting 300 participants with mild cognitive impairment and their study partners. The trial is being conducted at the Mayo Clinic campuses in Arizona, Florida, Minnesota, and the University of Washington in Seattle. The study examines the contribution of five behavioral interventions (yoga, memory compensation training, computerized cognitive training, support groups, and wellness education) on primary outcomes of participant and partner quality of life and self-efficacy. In this unique 10-day multicomponent intervention, groups of couples were randomized to have one of the five interventions withheld while receiving the other four. Although the longitudinal follow-up is still under way, enrollment results are available and reported. RESULTS: In total, 272 couples have been enrolled in the trial and follow-up visits continue. Outcomes will be assessed at the end-of-intervention and 6-, 12-, and 18-month follow-ups. We anticipate reporting on our primary and secondary outcomes across time points in the next 2 years. CONCLUSIONS: This paper describes the protocol for a randomized comparative effectiveness study of behavioral interventions to prevent or delay dementia. We describe of the rationale, design, power analysis, and analysis plan. Also because enrollment is complete and we are in follow-up phases of the study, we have included enrollment data from the trial.

Language treatment prior to anterior temporal lobe surgery: Can naming skills be preserved?

Epilepsy affects 1% of the general population and is highly prevalent among Veterans. The purpose of this phase I study was to investigate a presurgical linguistically distributed language treatment program that could potentially diminish effects of proper-name retrieval deficits following left anterior temporal lobe resection for intractable epilepsy. A single-subject multiple-baseline design was employed for three individuals with late-onset chronic left temporal lobe epilepsy. Word retrieval treatment was administered prior to anterior temporal lobe resection. The primary outcome measure was confrontation naming of proper nouns. Immediately posttreatment (before surgery), there was a positive effect for all trained stimuli in the form of improved naming as compared with pretreatment. In addition, trained stimuli were found to be better after surgery than they were at pretreatment baseline, which would not be expected had language treatment not been provided. This series of case studies introduces two fundamentally novel concept: that commonly occurring deficits associated with left temporal lobe epilepsy can be treated despite the presence of damaged neural tissue and that providing this treatment prior to surgery can lead to better preservation of language function after surgery than would be expected if the treatment were not provided.

Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) as a Cognitive Evaluation Tool for Patients with Normal Pressure Hydrocephalus.

External lumbar drainage (ELD) is recognized as a screening method for ventriculo-peritoneal shunting (VPS) candidacy for possible normal pressure hydrocephalus (NPH). This study focused on the ELD predictability of the cognitive outcome after VPS for NPH. In addition, Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) was examined in ELD cognition screening. ELD results were considered positive with any improvement in gait and/or cognition. Among 36 patients examined for possible NPH, 26 underwent VPS because of positive ELD. Cognitive outcome after VPS was assessed at 6-month follow-up. The RBANS scores, examined pre- and post-ELD, were evaluated statistically to identify consistency with the neuropsychologist judgment and the predictability of cognitive outcome after VPS. Among 26 shunted patients, gait was improved in 24. Cognitive improvement was rated in 19, and there were 9 false negative and 5 false positive in ELD cognition screening. The neuropsychologist judgment in ELD cognition screening is most consistent with the RBANS score in delayed memory. The patients rated as improved in cognition after VPS had significantly lower RBANS scores pre-ELD in immediate memory and delayed memory. If both scores at pre-ELD were ≤ 80 (13 patients), all were rated as improved in cognition after VPS. ELD screening was highly predictive of clinical gait improvement but not of cognitive improvement after VPS for possible NPH. Particularly among patients with a positive ELD gait response, pre-ELD low RBANS scores in memory predicted cognitive improvement after VPS. RBANS seems effective in evaluating cognition for NPH.

Better object recognition and naming outcome with MRI-guided stereotactic laser amygdalohippocampotomy for temporal lobe epilepsy.

OBJECTIVES: Patients with temporal lobe epilepsy (TLE) experience significant deficits in category-related object recognition and naming following standard surgical approaches. These deficits may result from a decoupling of core processing modules (e.g., language, visual processing, and semantic memory), due to "collateral damage" to temporal regions outside the hippocampus following open surgical approaches. We predicted that stereotactic laser amygdalohippocampotomy (SLAH) would minimize such deficits because it preserves white matter pathways and neocortical regions that are critical for these cognitive processes. METHODS: Tests of naming and recognition of common nouns (Boston Naming Test) and famous persons were compared with nonparametric analyses using exact tests between a group of 19 patients with medically intractable mesial TLE undergoing SLAH (10 dominant, 9 nondominant), and a comparable series of TLE patients undergoing standard surgical approaches (n=39) using a prospective, nonrandomized, nonblinded, parallel-group design. RESULTS: Performance declines were significantly greater for the patients with dominant TLE who were undergoing open resection versus SLAH for naming famous faces and common nouns (F=24.3, p<0.0001, η2=0.57, and F=11.2, p<0.001, η2=0.39, respectively), and for the patients with nondominant TLE undergoing open resection versus SLAH for recognizing famous faces (F=3.9, p<0.02, η2=0.19). When examined on an individual subject basis, no SLAH patients experienced any performance declines on these measures. In contrast, 32 of the 39 patients undergoing standard surgical approaches declined on one or more measures for both object types (p<0.001, Fisher's exact test). Twenty-one of 22 left (dominant) TLE patients declined on one or both naming tasks after open resection, while 11 of 17 right (nondominant) TLE patients declined on face recognition. SIGNIFICANCE: Preliminary results suggest (1) naming and recognition functions can be spared in TLE patients undergoing SLAH, and (2) the hippocampus does not appear to be an essential component of neural networks underlying name retrieval or recognition of common objects or famous faces.

Treatment of proper name retrieval deficits in an individual with temporal lobe epilepsy.

PURPOSE: Studies investigating language deficits in individuals with left temporal-lobe epilepsy have consistently demonstrated impairments in proper name retrieval. The aim of this Phase I rehabilitation study was to investigate the effects of a linguistically distributed word retrieval treatment on proper name retrieval in an individual with left temporal-lobe epilepsy. METHOD: A 61-year old right-handed male with left temporal-lobe epilepsy (clinical onset at the age of 50) and a deficit in proper name retrieval participated in this study. A single-subject, repeated-probe ABAA design with testing before, immediately after, and 3 months after treatment completion was employed. Proper name retrieval treatment was administered 2 hr per day for 5 days. RESULTS: Results demonstrated improved naming on trained items and maintenance of trained items 3 months after treatment completion. CONCLUSION: Treatment, which took advantage of the individual's undamaged linguistic networks, promoted the reorganization of networks supporting proper naming, leading to improved proper name retrieval. Further research replicating these findings in individuals with varying degrees of proper name retrieval impairment is warranted. Additionally, the mechanism behind the observed improvements in proper name retrieval needs to be investigated further using functional neuroimaging.

Famous face identification in temporal lobe epilepsy: support for a multimodal integration model of semantic memory.

This study aims to demonstrate that the left and right anterior temporal lobes (ATLs) perform critical but unique roles in famous face identification, with damage to either leading to differing deficit patterns reflecting decreased access to lexical or semantic concepts but not their degradation. Famous face identification was studied in 22 presurgical and 14 postsurgical temporal lobe epilepsy (TLE) patients and 20 healthy comparison subjects using free recall and multiple choice (MC) paradigms. Right TLE patients exhibited presurgical deficits in famous face recognition, and postsurgical deficits in both famous face recognition and familiarity judgments. However, they did not exhibit any problems with naming before or after surgery. In contrast, left TLE patients demonstrated both pre- and postsurgical deficits in famous face naming but no significant deficits in recognition or familiarity. Double dissociations in performance between groups were alleviated by altering task demands. Postsurgical right TLE patients provided with MC options correctly identified greater than 70% of famous faces they initially rated as unfamiliar. Left TLE patients accurately chose the name for nearly all famous faces they recognized (based on their verbal description) but initially failed to name, although they tended to rapidly lose access to this name. We believe alterations in task demands activate alternative routes to semantic and lexical networks, demonstrating that unique pathways to such stored information exist, and suggesting a different role for each ATL in identifying visually presented famous faces. The right ATL appears to play a fundamental role in accessing semantic information from a visual route, with the left ATL serving to link semantic information to the language system to produce a specific name. These findings challenge several assumptions underlying amodal models of semantic memory, and provide support for the integrated multimodal theories of semantic memory and a distributed representation of concepts.

Complementary and alternative medicine: use and disclosure in radiation oncology community practice.

PURPOSE: The aims of this study were to evaluate the frequency of complementary and alternative medicine (CAM) use among radiation oncology patients, the coping strategies that influenced this use, and the rates of disclosure of CAM use to their healthcare providers. METHODS: One hundred fifty-three patients undergoing radiation therapy for various neoplasms at rural cancer centers in Minnesota completed the Mayo Complementary and Alternative Medicine Use Survey and the Coping Inventory for Stressful Situations questionnaires. Data regarding CAM use was also compared with provider consultation notes in the medical record at the onset of radiation therapy to determine rates of patient disclosure of CAM use to their healthcare providers. RESULTS: A total of 153 participants completed the study with 61.4% females and 38.6% males and a mean age of 64.9 years. The two most frequent diagnoses of participants were breast cancer (43.8%) and prostate cancer (22.9%). CAM use was reported in 95% of the participants and was categorized into three domains: treatments and techniques, vitamins, and herbs and supplements. The three most frequently reported treatments and techniques were spiritual healing/prayer (62.1%), exercise (19.6%), and music (17.6%). The top three most frequently used biologically based CAM therapies were multivitamins (48.1%), calcium (37.3%), and vitamin with minerals (21.5%). The most frequently used herbs and other dietary supplements were fish oil (19.0%), flaxseed (15.0%), glucosamine (15.0%), and green tea (15.0%). The most common reason cited for CAM treatments and techniques use was previous use (26.1%), for use of vitamins and minerals was recommendation by a physician (33.0%), and for use of herbs and other supplements was previous use (19.0%). One hundred twelve participants reported taking vitamins, minerals, or supplements, and 47% of those 112 did not disclose this use to their providers. CONCLUSIONS: Consistent with previous research, our study found that the majority of cancer patients used CAM treatments. Spiritual healing/prayer was the most commonly reported, followed by multivitamins. Patients reported using CAM primarily due to previous use and physician recommendation. Unfortunately, disclosure of CAM use to healthcare providers was relatively low.

The Personality Assessment Inventory as a tool for diagnosing psychogenic nonepileptic seizures.

Using 184 subjects with valid personality assessment interview (PAI) profiles and video-electroencephalography (VEEG)-confirmed diagnoses of epileptic seizures (ES; n = 109) or psychogenic nonepileptic seizures (PNES; n = 75), we present the diagnostic test performance of the PAI PNES Indicator and other PAI scales when used to differentiate PNES from ES. Subjects with PNES reported significantly higher somatic, conversion, depressed, anxious, and suicidal symptoms. As a diagnostic tool, the PNES Indicator does not add additional accuracy beyond the conversion subscale (SOM-C). The somatization (SOM-S) and physiological depression (DEP-P) subscales perform as well as the SOM-C subscale. The SOM-C scale (cut point > or =70) was 58.7% sensitive and 83.5% specific at diagnosing PNES. Assuming a 30% prevalence of PNES, the SOM-C scale has a positive predictive value (PPV) of 60.4% and negative predictive value (NPV) of 82.5%. Overall, the PAI SOM-C subscale does not appear more accurate than other psychometric tests used to differentiate PNES from ES.

The mayo high performance teamwork scale: reliability and validity for evaluating key crew resource management skills.

PURPOSE: To develop and evaluate a participant rating scale for assessing high performance teamwork skills in simulation medicine settings. METHODS: In all, 107 participants in crisis resource management (CRM) training in a multidisciplinary medical simulation center generated 273 ratings of key CRM skills after participating in two or three simulation exercises. These data were analyzed using Rasch and traditional psychometric approaches to develop the 16-item Mayo High Performance Teamwork Scale (MHPTS). Sensitivity to change as a result CRM training was also evaluated. RESULTS: The MHPTS showed satisfactory internal consistency and construct validity by Rasch (person reliability = 0.77; person separation = 1.85; item reliability = 0.96; item separation = 5.04) and traditional psychometric (Cronbach's alpha = 0.85) indicators. The scale demonstrated sensitivity to change as a result of CRM training (pretraining mean = 21.44 versus first posttraining rating mean = 24.37; paired t = -4.15, P < 0.0001; first posttraining mean = 24.63 versus second posttraining mean = 26.83; paired t = -4.31 P < 0.0001). CONCLUSIONS: The MHPTS provides a brief, reliable, practical measure of CRM skills that can be used by participants in CRM training to reflect on and evaluate their performance as a team. Further evaluation of validity and appropriateness in other simulation and medical settings is desirable.
