The Effect of Self-efficacy-Enhancing Interventions on Quality of Life of Cancer Survivors: A Systematic Review.

BACKGROUND: The influence of self-efficacy-enhancing interventions on quality of life (QOL) is not clear with recent randomized controlled trials (RCTs) because current reviews only evaluated self-efficacy as an outcome. OBJECTIVES: We conducted a systematic review to examine the effect of self-efficacy-enhancing interventions on QOL among patients with cancer and to summarize the effective determinants for designing self-efficacy-enhancing interventions. METHODS: A systematic search was performed on studies published from January 2003 to May 2023 using PubMed, CINAHL, PsycINFO, and Web of Science. Included studies were RCTs, adults diagnosed with cancer, interventions with explicit self-efficacy components, and QOL as the outcome. RESULTS: Nineteen RCTs were included. Risk-of-bias assessment revealed 12 studies with some concerns and 7 with high risk of bias. The mean intervention adherence rate was 88.2%; the most frequently listed reason for dropout was medical conditions and mortality. Self-efficacy interventions were shown to significantly improve at least 1 subscale of QOL in 9 of 19 studies, of which 7 studies used Bandura's 4 sources of self-efficacy. The interventions with between-session intervals shorter than 2 weeks, of 12-week duration, and with an in-person delivery approach were the most effective. CONCLUSIONS: Self-efficacy-enhancing interventions show potential beneficial effects on QOL among cancer survivors. Interventions that use Bandura's 4 sources of self-efficacy strategies and have between-session intervals shorter than 2 weeks, an in-person approach, and 12-week intervention duration are recommended. IMPLICATIONS FOR PRACTICE: Properly designed self-efficacy-enhancing interventions can facilitate behavioral change and improve QOL in cancer survivors.

An Integrative Review of Sex Differences in Quality of Life and Symptoms Among Survivors of Hematologic Malignancies.

OBJECTIVES: To conduct an integrative review of studies to identify disparities in quality of life (QOL), symptoms, and symptom burden between men and women diagnosed with hematologic malignancies. SAMPLE & SETTING: 11 studies comprising 13,546 participants aged 18 years or older were included in the analysis. Studies were original peer-reviewed research published in English between January 2005 and December 2020. METHODS & VARIABLES: A literature search was performed using keywords associated with health-related QOL, hematologic malignancy, and sex/gender differences. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to identify relevant studies. Data were extracted for sex differences in QOL, symptoms, and symptom burden. All studies were appraised for quality and level of evidence. RESULTS: Women have worse physical health and function, more pain, and higher symptom burden compared with men. IMPLICATIONS FOR NURSING: Healthcare providers need to understand the impact of sex-based differences on QOL, symptoms, and symptom burden to provide optimal, personalized care.

Caregiver burden in caregivers of patients with advanced stage cancer: A concept analysis.

PURPOSE: Caregiver burden is a term used to describe the strain endured by the family member who is providing care for a patient and does not have formal training to do so. Caregiver burden is associated with a lack of self-efficacy, a decrease in the caregiver's quality of life, and high levels of anxiety and depression, that can worsen over time, impacting the well-being of the dyad. Due to the dynamic nature of caregiver burden, the precise understanding of this condition in relation to advanced stage cancer patients has not been fully conceptualized. Clarity of the nature of caregiver burden guides researchers, policy makers, and providers with a better understanding of what is needed to detect who the caregivers are and who is at most risk for severe caregiver burden. METHOD: An electronic search of the literature using PubMed, CINAHL, PsycINFO, and Cochrane Library databases informed the analysis. Quantitative and qualitative studies related to caregiver burden of the cancer patient, published in English between 2000 and 2021 were used. RESULTS: Of the over 20,000 articles initially identified, 19 ultimately met the inclusion criteria. Analysis identified the defining attributes of caregiver burden of the advanced stage cancer patient as: (1) decreased self-efficacy, (2) decreased quality of life, (3) increased anxiety, (4) increased depression, (5) and time sensitivity. Antecedents were identified as predictors of negative outcomes without intervention. Consequences were highlighted for those who are not supported. CONCLUSIONS: Caregiver burden impacts more than 2.8 million informal caregivers in the United States, who are providing complex care to patients with cancer without proper preparation. The conceptual understanding of caregiver burden guides the design of specific interventions to identify and prepare the caregiver for their critical role.

The Role of Influential Actors in Fostering the Polarized COVID-19 Vaccine Discourse on Twitter: Mixed Methods of Machine Learning and Inductive Coding.

Background: Since COVID-19 vaccines became broadly available to the adult population, sharp divergences in uptake have emerged along partisan lines. Researchers have indicated a polarized social media presence contributing to the spread of mis- or disinformation as being responsible for these growing partisan gaps in uptake. Objective: The major aim of this study was to investigate the role of influential actors in the context of the community structures and discourse related to COVID-19 vaccine conversations on Twitter that emerged prior to the vaccine rollout to the general population and discuss implications for vaccine promotion and policy. Methods: We collected tweets on COVID-19 between July 1, 2020, and July 31, 2020, a time when attitudes toward the vaccines were forming but before the vaccines were widely available to the public. Using network analysis, we identified different naturally emerging Twitter communities based on their internal information sharing. A PageRank algorithm was used to quantitively measure the level of "influentialness" of Twitter accounts and identifying the "influencers," followed by coding them into different actor categories. Inductive coding was conducted to describe discourses shared in each of the 7 communities. Results: Twitter vaccine conversations were highly polarized, with different actors occupying separate "clusters." The antivaccine cluster was the most densely connected group. Among the 100 most influential actors, medical experts were outnumbered both by partisan actors and by activist vaccine skeptics or conspiracy theorists. Scientists and medical actors were largely absent from the conservative network, and antivaccine sentiment was especially salient among actors on the political right. Conversations related to COVID-19 vaccines were highly polarized along partisan lines, with "trust" in vaccines being manipulated to the political advantage of partisan actors. Conclusions: These findings are informative for designing improved vaccine information communication strategies to be delivered on social media especially by incorporating influential actors. Although polarization and echo chamber effect are not new in political conversations in social media, it was concerning to observe these in health conversations on COVID-19 vaccines during the vaccine development process.

Translational Genomic Research: The Association between Genetic Profiles and Cognitive Functioning or Cardiac Function Among Breast Cancer Survivors Completing Chemotherapy.

Introduction: Emerging evidence suggests that Chemotherapy (CT) treated breast cancer survivors (BCS) who have "risk variants" in genes may be more susceptible to cognitive impairment (CI) and/or poor cardiac phenotypes. The objective of this preliminary study was to examine whether there is a relationship between genetic variants and objective/subjective cognitive or cardiac phenotypes. Methods and Analysis: BCS were recruited from Moffitt Cancer Center, Morsani College of Medicine, AdventHealth Tampa and Sarasota Memorial Hospital. Genomic DNA were collected at baseline for genotyping analysis. A total of 16 single nucleotide polymorphisms (SNPs) from 14 genes involved in cognitive or cardiac function were evaluated. Three genetic models (additive, dominant, and recessive) were used to test correlation coefficients between genetic variants and objective/subjective measures of cognitive functioning and cardiac outcomes (heart rate, diastolic blood pressure, systolic blood pressure, respiration rate, and oxygen saturation). Results: BCS (207 participants) with a mean age of 56 enrolled in this study. The majority were non-Hispanic white (73.7%), married (63.1%), and received both CT and radiation treatment (77.3%). Three SNPs in genes related to cognitive functioning (rs429358 in APOE, rs1800497 in ANKK1, rs10119 in TOMM40) emerged with the most consistent significant relationship with cognitive outcomes. Among five candidate SNPs related to cardiac functioning, rs8055236 in CDH13 and rs1801133 in MTHER emerged with potential significant relationships with cardiac phenotype. Conclusions: These preliminary results provide initial targets to further examine whether BCS with specific genetic profiles may preferentially benefit from interventions designed to improve cognitive and cardiac functioning following CT.

Feasibility and Acceptability of a Group Music Intervention in Memory Care Communities.

Music-based interventions have been shown to reduce behavioral expressions among persons with dementia. The goal of this study was to examine the feasibility and acceptability of a group music intervention to reduce agitation. Two memory care communities were recruited to participate in this single-arm mixed-methods study. The group music intervention program included a total of 12 sessions delivered over 4 weeks. Agitation was assessed quantitatively at weeks 0, 2, and 4. Qualitative interviews of memory care staff were conducted post-intervention. Data were analyzed using linear mixed-effects models and qualitative content analysis. The study sample (N = 19) had a mean age of 82.74, and 73.7% were female. The great majority of participants completed the intervention and 63.2% experienced a reduction in agitation, suggesting that the intervention is feasible and acceptable in memory care and may be efficacious. Future research should evaluate the efficacy of the intervention in a randomized controlled trial.

A Review and Conceptual Analysis of Cancer Pain Self-Management.

OBJECTIVES: In this concept analysis article, we will clarify the concept "self-management of cancer pain" by identifying related antecedents, attributes, and consequences to further refine the conceptual and operational definitions of the concept. DESIGN: A review was conducted. REVIEW/ANALYSIS METHODS: The Walker and Avant method was used for this concept analysis. DATA SOURCES: CINAHL, PubMed, and PsycInfo were searched systemically.A total of eight studies on "self-management of cancer pain or self-care of cancer pain" published between 2004 and 2019 were identified. RESULTS: Attributes for self-management of cancer pain include self-efficacy, integration of methods for pain relief into daily life, decision-making related to pain management, process for solving pain-related issues, and initiation of interactions with healthcare professionals. Antecedents include knowledge regarding pain assessment and management, cognitive abilities, motivation, undergoing pain treatment, patient education and counseling, social support, and accountability from all parties involved. Consequences include pain control, improved quality of life, and increased opioid intake. CONCLUSIONS: Self-management of cancer pain was reported to be a self-regulation process with the aim to encourage patients to use skills attained through development of self-efficacy, so they can actively participate in their pain management. This outcome may enhance their quality of life by decreasing their pain, depression, and anxiety and increasing the availability of social support.

Mindfulness-based stress reduction for breast cancer survivors (MBSR(BC)): evaluating mediators of psychological and physical outcomes in a large randomized controlled trial.

MBSR(BC) is known to have a positive impact on psychological and physical symptoms among breast cancer survivors (BCS). The cognitive mechanisms of "how" MBSR(BC) works was addressed in a recent study that found that there was strong consistent evidence that reduced emotional reactivity is a mediator and moderate consistent evidence that mindfulness, rumination, and worry were mediators. The purpose of this study, as part of a larger R01 trial, was to test whether positive effects achieved from the MBSR(BC) program were mediated through changes in increased mindfulness, decreased fear of breast cancer recurrence, and perceived stress. Female BCS > 21 years diagnosed with Stage 0-III breast cancer were randomly assigned to a 6-week MBSR(BC) or a Usual Care (UC)regimen. Potential mediators of 6- and 12-week outcomes were identified by analysis of covariance (ANCOVA), followed by formal mediational analyses of main effects of MBSR(BC) on 6- and 12-week outcomes, including percentage of total effects explained. Among 322 BCS (167 MBSR(BC) and 155 UC), fear of recurrence and perceived stress, but not mindfulness, mediated reductions in anxiety and fatigue at weeks 6 and 12, partially supporting our hypothesis of cognitive mechanisms of MBSR(BC).

Qigong mind-body program for caregivers of cancer patients: design of a pilot three-arm randomized clinical trial.

BACKGROUND: Informal caregivers, often family and friends, experience significant psychological and physical distress leading to reductions in health and quality of life (QOL). Mind-body interventions focused on caregivers are often limited and do not address multiple barriers, including caregivers' economic, geographic, and time constraints. Translation of in-person, community-based interventions to Internet-based delivery may offer greater accessibility for caregivers, leading to increased adherence. METHODS: Caring for Caregivers with Mind-Body implements a three-arm, pilot, randomized controlled trial to evaluate the feasibility of delivering a Qigong intervention (Eight Brocades) to cancer caregivers. A total of 54 cancer caregivers will be randomized into one of three 12-week programs: (1) community-based Qigong, (2) Internet-based Qigong, or (3) a self-care control group. Study-specific aims include (1) modify intervention content for online delivery, (2) evaluate the feasibility of recruiting and retaining cancer caregivers into a 12-week clinical trial, and (3) evaluate the feasibility of collecting and managing data, and the suitability of questionnaires for this population. Several outcomes will be assessed, including caregiver QOL, caregiver burden, caregiver distress, perceived social support, physical function, and cognitive function. A 6-month follow-up will also assess longer-term changes in QOL and psychosocial well-being. DISCUSSION: Findings will be used to inform the design and conduct of a large-scale comparative effectiveness trial evaluating caregivers who received Qigong training delivered through community-based vs Internet-based programs. A finding that either or both programs are effective would inform care and options for caregivers. TRIAL REGISTRATION: NCT04019301 ; registered on July 15, 2019; clinicaltrials.gov.

Anthracycline Chemotherapy-Induced Cardiotoxicity in Breast Cancer Survivors: A Systematic Review.

PROBLEM IDENTIFICATION: This review identifies specific cardiotoxicity related to anthracycline chemotherapy, specific risk factors related to increased anthracycline chemotherapy-induced cardiotoxicity, and underlying mechanisms of action of anthracycline chemotherapy-induced cardiotoxicity. LITERATURE SEARCH: PubMed®, CINAHL®, Embase®, and Web of Science were searched in May 2018 using keywords related to heart diseases, anthracycline chemotherapy, and breast cancer. DATA EVALUATION: Data were extracted, and study quality was assessed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. SYNTHESIS: 1,117 articles were identified through the literature search. After a review of the abstracts and articles, 15 clinical studies were identified for the final analysis by using exclusion and inclusion criteria. IMPLICATIONS FOR PRACTICE: Nurses should recognize the critical elements for prevention and early detection of anthracycline chemotherapy-induced cardiotoxicity.

Translational genomic research: the role of genetic polymorphisms in MBSR program among breast cancer survivors (MBSR[BC]).

Genetic variations of breast cancer survivors (BCS) may contribute to level of residual symptoms, such as depression, stress, fatigue, and cognitive impairment. The objective of this study was to investigate whether particular single-nucleotide polymorphisms (SNPs) moderated symptom improvement resulting from the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR[BC]) program. An overarching goal of personalized medicine is to identify individuals as risk for disease and tailor interventions based on genetic profiles of patients with diseases including cancer. BCS were recruited from Moffitt Cancer Center and University of South Florida's Breast Health Program and were randomized to either the 6-week MBSR(BC) program (n = 92) or Usual Care (n = 93). Measures of symptoms, demographic, and clinical history data were attained at baseline, 6 weeks, and 12 weeks. A total of 10 SNPs from eight genes known to be related to these symptoms were studied using genomic DNA extracted from blood. Our results were examined for effect sizes, consistency, and statistical significance (p < .05). Three SNPs (rs4680 in COMT, rs6314 in HTR2A, and rs429358 in APOE) emerged as having the strongest (though relatively weak) and most consistent effects in moderating the impact of the MBSR program on symptom outcomes. Although effects were generally weak, with only one effect withstanding multiple comparisons correction for statistical significance, this translational behavioral research may help start the identification of genetic profiles that moderate the impact of MBSR(BC). The ultimate goal of this study is the development of personalized treatment programs tailored to the genetic profile of each patient.

A Large Randomized Trial: Effects of Mindfulness-Based Stress Reduction (MBSR) for Breast Cancer (BC) Survivors on Salivary Cortisol and IL-6.

Breast cancer survivors (BCS) often experience psychological and physiological symptoms after cancer treatment. Mindfulness-based stress reduction (MBSR), a complementary and alternative therapy, has reduced subjective measures of stress, anxiety, and fatigue among BCS. Little is known, however, about how MBSR affects objective markers of stress, specifically the stress hormone cortisol and the pro-inflammatory cytokine interleukin-6 (IL-6). In the present study, BCS ( N = 322) were randomly assigned to a 6-week MBSR program for BC or usual-care control. Measurements of cortisol, IL-6, symptoms, and quality of life were obtained at orientation and 6 weeks. Cortisol and IL-6 were also measured prior to and after the MBSR(BC) class Weeks 1 and 6. The mean age of participants was 56.6 years and 69.4% were White non-Hispanic. Most had Stage I (33.8%) or II (35.7%) BC, and 35.7% had received chemotherapy and radiation. Cortisol levels were reduced immediately following MBSR(BC) class compared to before the class Weeks 1 and 6 (Wilcoxon-signed rank test; p < .01, d = .52-.56). IL-6 was significantly reduced from pre- to postclass at Week 6 (Wilcoxon-signed rank test; p < .01, d = .21). No differences were observed between the MBSR(BC) and control groups from baseline to Week 6 using linear mixed models. Significant relationships with small effect sizes were observed between IL-6 and both symptoms and quality of life in both groups. Results support the use of MBSR(BC) to reduce salivary cortisol and IL-6 levels in the short term in BCS.

Feasibility of the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program for symptom improvement among breast cancer survivors.

OBJECTIVE: The purpose of this pilot study was to test the feasibility of delivering the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program using an iPad and to evaluate its impact on symptom improvement. METHODS: A single group, pre-posttest design was implemented among female stages 0-III breast cancer survivors (BCS) who completed treatment. Data were collected at baseline and week 6 on measures of psychological and physical symptoms and quality of life. The mMBSR(BC) program is a standardized, stress-reducing intervention that combines sitting and walking meditation, body scan, and yoga and is designed to deliver weekly 2-hour sessions for 6 weeks using an iPad. RESULTS: The mean age of the 15 enrolled BCS was 57 years; one participant was non-Hispanic black, and 14 were non-Hispanic white. Of the 13 who completed the study, there were significant improvements from baseline to 6 weeks post-mMBSR(BC) in psychological and physical symptoms of depression, state anxiety, stress, fear of recurrence, sleep quality, fatigue, and quality of life (P's < .05). Effect sizes for improvements of multiple symptoms ranged from medium to large. CONCLUSIONS: These results provide preliminary support that the mMBSR(BC) program may be feasible and acceptable, showing a clinical impact on decreasing psychological and physical symptoms. This mobile-based program offers a delivery of a standardized MBSR(BC) intervention to BCS that is convenient for their own schedule while decreasing symptom burden in the survivorship phase after treatment for breast cancer.

A Randomized Controlled Trial of the Effects of Mindfulness-Based Stress Reduction (MBSR[BC]) on Levels of Inflammatory Biomarkers Among Recovering Breast Cancer Survivors.

PURPOSE: The purpose of this substudy of a large randomized controlled trial was to evaluate the efficacy of the Mindfulness-Based Stress Reduction (Breast Cancer) (MBSR[BC]) program compared to usual care (UC) in normalizing blood levels of pro-inflammatory cytokines among breast cancer survivors (BCS). METHOD: A total of 322 BCS were randomized to either a 6-week MBSR(BC) program or a UC. At baseline and 6 and 12 weeks, 10 ml of venous blood and demographic and clinical data were collected and/or updated. Plasma cytokines (interleukin [IL]-1ß, IL-6, IL-10, tumor necrosis factor [TNF] α, transforming growth factor [TGF] ß1, soluble tumor necrosis factor receptor [sTNFR] 1) were assayed. Linear mixed models were used to assess cytokine levels across three time points (baseline and 6 and 12 weeks) by group (MBSR[BC] vs. UC). RESULTS: Of the six measured cytokines, three were nondetectable at rates greater than 50% (IL-10, IL-1ß, TGF-ß1) and, because of overall low prevalence, were not analyzed further. For the remaining cytokines (TNFα, IL-6, sTNFR1), results showed that TNFα and IL-6 increased during the follow-up period (between 6 and 12 weeks) rather than during the MBSR(BC) training period (between baseline and 6 weeks), while sTNFR1 levels did not change significantly across the 12-week period. CONCLUSIONS: Study results suggest that MBSR(BC) affects cytokine levels in BCS, mainly with increases in TNFα and IL-6. The data further suggest that B-cell modulation may be a part of immune recovery during breast cancer management and that increases in TNFα and IL-6 may be markers for MBSR(BC)-related recovery.

Mindfulness-Based Stress Reduction in Post-treatment Breast Cancer Patients: Immediate and Sustained Effects Across Multiple Symptom Clusters.

CONTEXT: Breast cancer survivors (BCS) face adverse physical and psychological symptoms, often co-occurring. Biologic and psychological factors may link symptoms within clusters, distinguishable by prevalence and/or severity. Few studies have examined the effects of behavioral interventions or treatment of symptom clusters. OBJECTIVES: The aim of this study was to identify symptom clusters among post-treatment BCS and determine symptom cluster improvement following the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR(BC)) program. METHODS: Three hundred twenty-two Stage 0-III post-treatment BCS were randomly assigned to either a six-week MBSR(BC) program or usual care. Psychological (depression, anxiety, stress, and fear of recurrence), physical (fatigue, pain, sleep, and drowsiness), and cognitive symptoms and quality of life were assessed at baseline, six, and 12 weeks, along with demographic and clinical history data at baseline. A three-step analytic process included the error-accounting models of factor analysis and structural equation modeling. RESULTS: Four symptom clusters emerged at baseline: pain, psychological, fatigue, and cognitive. From baseline to six weeks, the model demonstrated evidence of MBSR(BC) effectiveness in both the psychological (anxiety, depression, perceived stress and QOL, emotional well-being) (P = 0.007) and fatigue (fatigue, sleep, and drowsiness) (P < 0.001) clusters. Results between six and 12 weeks showed sustained effects, but further improvement was not observed. CONCLUSION: Our results provide clinical effectiveness evidence that MBSR(BC) works to improve symptom clusters, particularly for psychological and fatigue symptom clusters, with the greatest improvement occurring during the six-week program with sustained effects for several weeks after MBSR(BC) training.

Examination of Broad Symptom Improvement Resulting From Mindfulness-Based Stress Reduction in Breast Cancer Survivors: A Randomized Controlled Trial.

PURPOSE: The purpose of this randomized trial was to evaluate the efficacy of the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR[BC]) program in improving psychological and physical symptoms and quality of life among breast cancer survivors (BCSs) who completed treatment. Outcomes were assessed immediately after 6 weeks of MBSR(BC) training and 6 weeks later to test efficacy over an extended timeframe. PATIENTS AND METHODS: A total of 322 BCSs were randomly assigned to either a 6-week MBSR(BC) program (n = 155) or a usual care group (n = 167). Psychological (depression, anxiety, stress, and fear of recurrence) and physical symptoms (fatigue and pain) and quality of life (as related to health) were assessed at baseline and at 6 and 12 weeks. Linear mixed models were used to assess MBSR(BC) effects over time, and participant characteristics at baseline were also tested as moderators of MBSR(BC) effects. RESULTS: Results demonstrated extended improvement for the MBSR(BC) group compared with usual care in both psychological symptoms of anxiety, fear of recurrence overall, and fear of recurrence problems and physical symptoms of fatigue severity and fatigue interference (P < .01). Overall effect sizes were largest for fear of recurrence problems (d = 0.35) and fatigue severity (d = 0.27). Moderation effects showed BCSs with the highest levels of stress at baseline experienced the greatest benefit from MBSR(BC). CONCLUSION: The MBSR(BC) program significantly improved a broad range of symptoms among BCSs up to 6 weeks after MBSR(BC) training, with generally small to moderate overall effect sizes.

Body Image in Younger Breast Cancer Survivors: A Systematic Review.

BACKGROUND: Body image is a complex issue with the potential to impact many aspects of cancer survivorship, particularly for the younger breast cancer survivor. OBJECTIVE: The purpose of this review is to synthesize the current state of the science for body image in younger women with breast cancer. METHODS: Combinations of the terms "body image," "sexuality intervention," "women," "younger women," and "breast cancer" were searched in the PubMed, PsycINFO, CINAHL, Web of Knowledge, and Science Direct databases through January 2014. Inclusion criteria for this review were (1) original research, (2) published in English from the year 2000 forward, (3) measuring body image as an outcome variable, and (4) results included reporting of age-related outcomes. RESULTS: Thirty-six articles met the inclusion criteria. The majority of studies were cross-sectional, with extensive variation in body image assessment tools. Age and treatment type had a significant impact on body image, and poorer body image was related to physical and psychological distress, sex and intimacy, and the partnered relationship among younger women. Only 1 intervention study found a significant improvement in body image after intervention. CONCLUSIONS: Findings suggest body image is a complex posttreatment concern for breast cancer survivors, particularly younger women. The findings of this review are limited by the high level of variation in the methods for assessing body image. IMPLICATIONS FOR PRACTICE: Further research of interventions to address body image concerns following treatment for breast cancer is warranted. Improvement of body image may improve the quality of life of younger breast cancer survivors.

Mecanismos neurocognitivos de la terapia basada en Mindfulness / Neurocognitive mechanisms of the Mindfulness based therapy

Presentamos un resumen y una breve historia del creciente campo de Intervenciones Basadas en mindfulness o conciencia plena. En los últimos tiempos, existe un gran interés en este modelo terapéutico para reducir la vulnerabilidad al estrés crónico y distrés emocional. Mindfulness requiere intencionalmente enfocar nuestra atención a las experiencias que ocurren en el momento presente. A medida que la investigación avanza en esta temática, es vital definir cuidadosamente la estructura de mindfulness y comprender mejor sus mecanismos de acción neurocognitiva. Este informe presenta un marco conceptual que enfatiza el papel central de control atencional y mecanismos de sostenibilidad para desarrollar las habilidades de conciencia plena. También, repasamos la estructura de mindfulness y la autorregulación de las emociones; luego describimos brevemente nuestra investigación relacionada con nuestro programa de Reducción del Estrés en Cáncer de Mama basado en Mindfulness (MBSR-AC) en la University of South Florida. Se presenta, a partir de esta premisa, un modelo propuesto que explica nuestros mecanismos cognitivos basados en la lógica del modelo de biocomportamental.

We are presenting an overview and a brief history of the growing field of Mindfulness Based Interventions. There has been a significant interest in this therapeutic model to reduce vulnerability to chronic stress and emotional distress in recent times. Mindfulness requires intentionally bringing our attention to the experiences that occur in the present moment. As the research advances in this line of inquiry, it is vital to carefully define the construct of Mindfulness and better understand its neurocognitive mechanisms of action. This review presents conceptual framework that emphasizes the central role of attentional control and sustainability mechanisms to build mindfulness skills. We also review the construct of Mindfulness and self-regulation of emotions; then describe briefly our research related to our Mindfulness Based-Stress Reduction Breast Cancer (MBSR-BC) program at the University of South Florida. With this premise, we present a model explaining our proposed cognitive mechanisms based on the Logic of the Biobehavioral Model.

A Cost-Effective Mindfulness Stress Reduction Program: A Randomized Control Trial for Breast Cancer Survivors.

Many breast cancer survivors continue to experience residual symptoms including anxiety, cognitive impairment, depression, fatigue, and pain. In this study, the cost-effectiveness of a Mindfulness-Based Stress Reduction intervention for breast cancer survivors was examined. The cost of the program was assessed from the societal perspective, accounting for both direct medical and patient opportunity costs. The cost per quality-adjusted life year was relatively low compared to the cost-utility findings of other published breast cancer interventions. The program appears to provide for significantly improved health-related quality of life at a comparativelv low cost.

Moderating Effects of Genetic Polymorphisms on Improvements in Cognitive Impairment in Breast Cancer Survivors Participating in a 6-Week Mindfulness-Based Stress Reduction Program.

Breast cancer (BC) survivors often report cognitive impairment, which may be influenced by single-nucleotide polymorphisms (SNPs). The purpose of this study was to test whether particular SNPs were associated with changes in cognitive function in BC survivors and whether these polymorphisms moderated cognitive improvement resulting from the Mindfulness-Based Stress Reduction for Breast Cancer (MBSR[BC]) program. BC survivors recruited from Moffitt Cancer Center and the University of South Florida's Breast Health Program, who had completed adjuvant radiation and/or chemotherapy treatment, were randomized to either the 6-week MBSR(BC) program (n = 37) or usual care (UC; n = 35) group. Measures of cognitive function and demographic and clinical history data were attained at baseline and at 6 and 12 weeks. A total of 10 SNPs from eight genes known to be related to cognitive function were analyzed using blood samples. Results showed that SNPs in four genes (ankyrin repeat and kinase domain containing 1 [ANKK1], apolipoprotein E [APOE], methylenetetrahydrofolate reductase [MTHFR], and solute carrier family 6 member 4 [SLC6A4]) were associated with cognitive impairment. Further, rs1800497 in ANKK1 was significantly associated with improvements in cognitive impairment in response to MBSR(BC). These results may help to identify individuals who would be better served by MBSR(BC) or other interventions.
