ABSTRACT Background Chemotherapy‐induced peripheral neuropathy (CIPN), characterized by loss of sensation and impaired physical function, is a prevalent and debilitating side effect of chemotherapy, affecting 30%–50% of breast cancer survivors (BCS) with effects lasting years after treatment completion. Mindfulness‐based interventions are shown to be efficacious in reducing symptoms in neuropathies. This subgroup analysis examined the effect of Mindfulness‐Based Stress Reduction on Breast Cancer (MBSR(BC)) compared to Breast Cancer Education Support (BCES) or Usual Care (UC) on CIPN among BCS who received chemotherapy or chemotherapy and radiation. Methods BCS ( n = 114) were randomly assigned to the 6‐week MBSR(BC) ( n = 48), BCES ( n = 52), or UC ( n = 14) regimen. Demographic and clinical data were assessed at baseline, and CIPN was assessed using the Chemotherapy‐Induced Peripheral Neuropathy assessment tool (CIPNAT) at baseline, 6, 12, and 26 weeks. Between‐ and within‐group differences were evaluated and change over time was compared between groups. Results BCS (mean age = 52.7 years, range: 28–81 years) were primarily White and non‐Hispanic ( n = 78, 68%). The pattern of effect sizes was similar for CIPNAT symptoms and interference with improvements in CIPN for MBSR(BC) and BCES groups overtime. For both groups, the effects were larger compared to the UC. Differences tended to increase over time with significant effects observed between MBSR(BC) and UC, and between BCES and UC at weeks 12 and 26. Conclusions The findings indicate that MBSR(BC) and BCES may effectively reduce CIPN symptoms among BCS compared to UC. MBSR(BC) and BCES programs are effective non‐pharmacological interventions for CIPN that may translate into practice.

ABSTRACTObjectiveTo conduct an economic evaluation of a group mindfulness program compared to an education support program for breast cancer survivors (BCS).MethodsThe cost‐utility analysis (cost per quality‐adjusted life year [QALY]) was performed from a single‐center randomized controlled trial in the United States. Data from 181 BCS were included in the analysis (91 from the mindfulness‐based stress reduction for breast cancer, MBSR(BC) and 90 from the Breast Cancer Education Support, (BCES)). Analyses were conducted from two perspectives: societal and healthcare system. The EuroQol EQ‐5D‐5L was used to measure quality of life and the Client Service Receipt Inventory (CSRI) was used to measure health services utilization from baseline through 26 weeks. The impact of MBSR(BC) on health services utilization and costs was estimated with generalized linear models.ResultsIn the reference case analyses (societal perspective), the average total cost in the MBSR(BC) group was $5744 compared with $6140 in the BCES group. At the end of follow‐up, the MBSR(BC) group dominated BCES in terms of Incremental Cost Utility Ratio (ICUR), with MBSR(BC) providing an incremental cost of −$541 (95% CI: −$3400, $2318) and a 0.021 QALY (95% CI: −0.014, 0.055). Net monetary benefit (NMB) analysis showed that MBSR(BC) has a higher probability of achieving positive NMB across a range of possible societal willingness‐to‐pay for improving quality of life.ConclusionsOur findings suggest that MBSR(BC) is likely to be cost‐effective for breast cancer survivors over 6 months. Cost savings primarily resulted from reduced ER and hospital admissions and tests.

Introduction: The Mindfulness-Based Stress Reduction program for breast cancer survivors (MBSR [BCs]) is a stress-reducing program designed to increase cognitive functioning through four meditational practices. This randomized clinical trial aimed to determine if improvements in cognitive functioning and perceived cognitive abilities achieved from the MBSR(BC) were mediated through increased mindfulness, decreased rumination, and decreased perceived stress. Methods: Breast cancer survivors (BCSs) who met inclusion criteria of stage I, II, or III BC and received either chemotherapy (CT) or both CT and radiation were randomized to either the 6-week MBSR(BC), or Breast Cancer Education Support (BCES) program, or to a usual care (UC) regimen. Analysis of covariance was first implemented to identify potential mediators, followed by a formal mediational analysis to evaluate the effects of MBSR(BC) on 6-, 12-, and 26-week outcomes. Results: After consent, 212 BCS were randomized to MBSR(BC) ( n = 91), BCES ( n = 90), or UC ( n = 31). The mean age was 56.5 and the majority of the BCS, 73.1%, were White and non-Hispanic. Results showed increases in “observing” as part of mindfulness as a potential mediator of MBSR(BC) effects on impairments on quality of life and logical memory at 6 months relative to UC. No mediation effects were identified for outcomes measured at 6 or 12 weeks and also when MBSR(BC) was compared with the BCES program. Discussion: These results partially supported our hypothesis that improvement in cognitive functioning would occur through increased mindfulness. Although few mediating relationships were identified, results showed a relationship between mindfulness and cognitive functioning. Both mediating relationships occurred through increases in “observing,” a subconcept of “mindfulness,” when compared to the MBSR(BC) with UC at 6 months. This study shows that mediators may help “optimize” clinical therapeutic treatment effects, thus contributing to the advancement of science.

Background Genetics may influence symptoms experienced by breast cancer survivors (BCS) by moderating the effects of stress-reducing interventions, including the Mindfulness-Based Stress Reduction (MBSR(BC)) program, to reduce symptom severity. As part of a larger clinical trial, the aim of this study was to evaluate genetic variants as moderators of MBSR(BC) on improvements among BCS in cognitive functioning and symptoms. Methods BCS ( n = 128) were randomized to MBSR(BC) or the Breast Cancer Education Support Program. Objective neuropsychological and subjective measures of cognitive performance, and psychological and physical symptoms were collected at baseline, 6, 12, and 26 weeks. Linear mixed models were implemented to identify MBSR(BC)’s effects over time. A total of 22 single nucleotide polymorphisms (SNPs) from 20 genes known to be related to these symptoms were investigated using genomic DNA. These SNPs were tested as moderators of MBSR(BC) program effects. Results Results showed MBSR(BC) participants experienced significantly greater benefits in cognitive functioning, however, the level of benefit varied based on one’s genetic profile. Effects sizes, consistency across similar measures were investigated. Among 22 candidate SNPs, rs4680 in COMT, rs1800497 in ANKK1, and rs6277 in DRD2 demonstrated the strongest, most consistent positive effects in moderating MBSR(BC)’s impact on cognitive outcomes. Conclusions Although the effects were small, this translational research may potentially identify BCS with genotypes that would be most influenced by the MBSR(BC) program. These results may be used to develop personalized intervention programs tailored to the genetic profile of each breast cancer survivor who received chemotherapy or chemotherapy and radiation.

Introduction: The Mindfulness-Based Stress Reduction (MBSR) Program for breast cancer survivors (BCS) is designed to enhance cognitive training through formal and informal meditational practices. This randomized clinical trial (RCT) aimed to evaluate if BCS assigned to either the MBSR(BC), Breast Cancer Education Support (BCES), or Usual Care (UC) regimens experienced greater improvements at 6, 12, and 26 weeks on objective and subjective cognitive performance. Methods: BCS ( n = 212) randomized to a three-group RCT: MBSR(BC) ( n = 91), BCES ( n = 90), or UC ( n = 31) were assessed on cognitive performance and symptoms at baseline, 6, 12, and 26 weeks. Linear mixed models were fit to evaluate the effects of the MBSR(BC) program, hypothesizing ordered effect improvements: (MBSR[BC] highest, BCES intermediate, UC lowest) along with baseline characteristics evaluated as moderators. Results: Of the BCS (mean age of 57), 73% were White, and non-Hispanic, and 77% received both chemotherapy (CT) and radiation. Cognitive performance improved in all groups. Although there were no statistically significant between-group differences in cognitive outcomes, significant symptom reductions occurred for the MBSR(BC) group ( p = 0.003). Within-group effect size analysis at 26 weeks showed substantial improvements in all three groups (effect sizes >0.50) in subjective impairments and quality of life (effect size >0.50) and objective measures of cognitive performance. MBSR(BC) showed the largest within-group effect size in the reduction of fatigue (effect size = 0.81). Effect sizes occurred in the hypothesized direction for 10 of the 18 outcomes. Discussion: Although the MBSR(BC) program did not show significant differences in cognitive performance compared with BCES and UC, all groups improved and reductions in fatigue were beneficial for MBSR(BC). Results suggest that cognitive performance may improve after CT over time considering one’s natural history. Furthermore, BCS enrolled in RCTs may be more motivated to improve their health status (NCT02786797).

Introduction : The incidence of spontaneous clinical improvement in acute cardiomyopathy (ACM) patients treated with evidence based medical therapy is unknown. We hypothesized that pts without LV dilatation at presentation would have the greatest potential for recovery of ejection fraction (EF). Methods: A multi-center NHLBI sponsored trial, Intervention in Myocarditis and Acute Cardiomyopathy II (IMAC 2) was designed to study the clinical course of ACM and the mechanisms associated with outcomes. A clinical, echocardiography, and genetics core lab are established. Results: 15 centers have enrolled 215 pts, mean age 45 ± 14 yrs, 34% female, NYHA class I–IV% 18/54/21/7, baseline EF 0.25 ± 0.09. Therapy included 80% beta blockers and 92% ACE or ARB treated. All patients enrolled had symptoms for ≤ 6 mos and were diagnosed with acute, idiopathic cardiomyopathy or myocarditis. Baseline and 6 mo echoes in 140 pts reviewed by the core lab demonstrated increased ejection fraction (EF): 0.25 ± 0.09 to 0.40 ± 0.11 p<0.001; mean increase 0.15 ± 0.10. Recovery in EF from baseline to 6 mos was related to LVEDD at baseline as shown in the Figure . Kaplan Meier survival n=207 at 1 and 2 years 96% and 94% and transplant free survival at 1 and 2 yrs 92% and 91%. Conclusions: Results of IMAC 2 reveal a marked spontaneous improvement in EF over 6 months, greatest in those with non-dilated LVEDD at baseline, and excellent overall survival in ACM pts treated with evidence based therapies.

Little is known about the experience of family caregivers when their care partner dies and their dyadic relationship comes to an end. This study qualitatively examined and characterized the loss of the dyadic experience for the caregiver after the death of their care partner. Data was accrued as part of a randomized clinical trial in 29 older hospice caregivers. Iterative thematic analysis focused on dyadic processes before, during and post death. Using two relational parameters from Relational Turbulence Theory resulted in a preliminary characterization of a new concept—dyadic dissolution as a cognitive and affective process whereby a remaining member of a dyad experiences relational uncertainty and partner interference while adapting (or not) to the death of their care partner. Findings suggest that asking several open-ended questions about the dyadic relationship will enable assessment for any continuing impact of relational uncertainty and partner interference on bereaved caregivers.

Abstract Complicated grief (CG), severe, prolonged (&gt;12 months) grieving, disproportionately affects older adults. A prospective two-group, waitlisted RCT examined whether four sessions of Accelerated Resolution Therapy (ART) was effective in informal caregivers by comparing pre-to-post ART changes and investigating variation in treatment response by baseline CG levels. Inclusion: ≥60 years, Inventory of Complicated Grief &gt;25. Paired t-tests of mean (SD) differences compared pre- to post-ART; pre-ART to 8-week follow-up, and post-ART to 8-week follow-up; then stratified by median baseline level of CG. Mean (SD) age of 54 participants was 68.7 (7.2) years, 85% female, and 93% white. Significantly greater CG reduction (-22.8 (10.3)) vs. waitlist (-4.3 (6.0)) was found. Within-participant effect sizes from baseline to 8-weeks post treatment were 1.96 (95% CI: 1.45, 2.47; p&lt;0.0001). Treatment effects did not substantially differ by baseline levels. Lesson learned was that it was possible to successfully recruit and treat CG in the community.

Biomarkers may serve as objective measures in complicated grief (CG) potentially capturing responses to stress reduction treatment. This paper reports challenges in obtaining and assessing salivary cortisol and α-amylase (sAA) for a recent randomized clinical trial. Within-session changes in salivary cortisol and sAA for 54 older adults with CG who received Accelerated Resolution Therapy were compared with perceived stress measured by Subjective Units of Distress Scale. Bivariate correlations and multiple regressions examined changes in biomarkers. Protocols, study logs, and audit reports identified challenges. Challenges included obtaining unstimulated passive drool salivary samples and their analyses. Our sample of older females on multiple medications may have resulted in a perfect storm of moderating and intervening variables which affected the stress response. This paper contributes to the discussion on designing clinical trials for older adults which must account for physiologic changes, multimorbidity, and polypharmacy common in this population and makes recommendations moving forward.

Complicated grief is a significant health concern for older adults, resulting in significant psychological and physical morbidity. Elements of post traumatic stress disorder (PTSD) are often present in individuals with complicated grief. Accelerated Resolution Therapy (ART) is a brief form of psychotherapy that utilizes the techniques of imaginal exposure, rescripting of events, and lateral eye movements that may be useful in complicated grief with PTSD symptoms. Two cases where ART was used for complicated grief with PTSD are presented. Both individuals had attempted to come to terms with their loss through traditional grief therapy with an inadequate response and substantial residual grief symptoms. These cases illustrate how ART can be used to address CG and PTSD and describe situations where it may be appropriate. Clinical and research implications are also discussed.
