Psychoneuroendocrinology. 86:78-86, 2017 Dec.

Abstract

OBJECTIVE: Mindfulness training has been shown to improve psychological well-being and physical health. One proposed pathway for the positive effects of mindfulness training is through the development of new emotion regulation strategies, such as the ability to experience emotions by observing and accepting them without judgment. Theoretically, this should facilitate recovery from negative emotional states; however, this has rarely been examined empirically. The goal of the current study was to determine whether mindfulness training is associated with more efficient emotional and cardiovascular recovery from induced negative affect.

METHODS: The current study tested emotional and cardiovascular recovery from induced negative affect during a personal recall task in women randomly assigned to 6-weeks of mindfulness training (n=39) compared to women assigned to a wait-list control condition (n=32). During baseline, task, and post-task rest, blood pressure and heart rate were monitored at fixed intervals and heart rate variability (HRV) and pre-ejection period (PEP) were monitored continuously. This study was embedded within a randomized trial that evaluated the effects of mindfulness training in a sample of younger breast cancer survivors, a group in need of access to effective psychosocial intervention as they can experience high stress, anxiety, and physical symptoms for many years in to survivorship.

RESULTS: In response to the personal recall task, women in both the intervention and control groups showed significant increases in sadness, anxiety, and anger, with the intervention group reaching higher levels of sadness and anger than controls. Further, the intervention group showed a significantly steeper decline in sadness and anger, as well as steeper initial decline in diastolic blood pressure compared to women in the wait list control condition. Groups did not differ in their self-reported feelings of anxiety, or in blood pressure, heart rate, or pre-ejection period (PEP) responses to the task. The control group demonstrated an increase in heart rate variability (HRV) during the task (indexed by the root mean square of successive differences in heart rate; RMSSD) while the intervention group remained flat throughout the task.

CONCLUSION: Compared to the control group, women in the intervention group experienced greater negative emotions when recalling a difficult experience related to their breast cancer, and demonstrated an efficient emotional and blood pressure recovery from the experience. This suggests that mindfulness training may lead to an enhanced emotional experience coupled with the ability to recovery quickly from negative emotional states.

Title

Effects of physical activity on depressive symptoms during breast cancer survivorship: a meta-analysis of randomised control trials.

Source

Esmo Open. 2(5):e000271, 2017.

Abstract

Background: Breast cancer is one of the most common cancers affecting women worldwide, and depressive symptoms are disturbing side effects of cancer diagnosis and treatment. Physical activity and exercise have emerged as an alternative treatment in handling psychological distress throughout breast cancer survivorship.

Aim: The aim of this review was to present the results of (1) physical activity and (2) exercise interventions in terms of type and duration regarding depressive symptoms among breast cancer survivors during and after treatment. The hypothesis was that cancer survivors who are engaged with physical activity will demonstrate statistically significant lower levels of depressive symptoms when compared with non-exercising control groups.

Methods: We searched PubMed, Elsevier and Google Scholar for recent articles published between January 2011 and November 2016. Fourteen randomised control trials with 1701 patients in total were assessed.

Results: Significant differences in levels were found between exercise intervention groups and control groups, while moderate aerobic exercise interventions with an optimal duration of >=135min for up to 12 weeks are significantly more beneficial in depressive symptoms when it comes to patients under treatment than resistance, aerobic and resistance training and yoga interventions.

Conclusions: It is concluded that when progressive exercise programmes are prescribed according to the individual needs, capabilities and preferences of breast cancer survivors, they offer a valid alternative to depression mood management throughout the course of survivorship.

Title

Randomized trial of Tibetan yoga in patients with breast cancer undergoing chemotherapy.

Source

Cancer. 124(1):36-45, 2018 Jan 01.

Abstract

BACKGROUND: The current randomized trial examined the effects of a Tibetan yoga program (TYP) versus a stretching program (STP) and usual care (UC) on sleep and fatigue in women with breast cancer who were undergoing chemotherapy.

METHODS: Women with stage (American Joint Committee on Cancer (AJCC) TNM) I to III breast cancer who were undergoing chemotherapy were randomized to TYP (74 women), STP (68 women), or UC (85 women). Participants in the TYP and STP groups participated in 4 sessions during chemotherapy, followed by 3 booster sessions over the subsequent 6 months, and were encouraged to practice at home. Self-report measures of sleep disturbances (Pittsburgh Sleep Quality Index), fatigue (Brief Fatigue Inventory), and actigraphy were collected at baseline; 1 week after treatment; and at 3, 6, and 12 months.

RESULTS: There were no group differences noted in total sleep disturbances or fatigue levels over time. However, patients in the TYP group reported fewer daily disturbances 1 week after treatment compared with those in the STP (difference, -0.43; 95% confidence interval [95% CI], -0.82 to -0.04 [P=.03]) and UC (difference, -0.41; 95% CI, -0.77 to -0.05 [P=.02]) groups. Group differences at the other time points were maintained for TYP versus STP. Actigraphy data revealed greater minutes awake after sleep onset for patients in the STP group 1 week after treatment versus those in the TYP (difference, 15.36; 95% CI, 7.25-23.48 [P=.0003]) and UC (difference, 14.48; 95% CI, 7.09-21.87 [P=.0002]) groups. Patients in the TYP group who practiced at least 2 times a week during follow-up reported better Pittsburgh Sleep Quality Index and actigraphy outcomes at 3 months and 6 months after treatment compared with those who did not and better outcomes compared with those in the UC group.

CONCLUSIONS: Participating in TYP during chemotherapy resulted in modest short-term benefits in sleep quality, with long-term benefits emerging over time for those who practiced TYP at least 2 times a week.

Title

Randomized Trial of ConquerFear: A Novel, Theoretically Based Psychosocial Intervention for Fear of Cancer Recurrence.

Source

Journal of Clinical Oncology. 35(36):4066-4077, 2017 Dec 20.

Abstract

Purpose:  Fear of cancer recurrence (FCR) is prevalent, distressing, and long lasting. This study evaluated the impact of a theoretically/empirically based intervention (ConquerFear) on FCR.

Methods: Eligible survivors had curable breast or colorectal cancer or melanoma, had completed treatment (not including endocrine therapy) 2 months to 5 years previously, were age > 18 years, and had scores above the clinical cutoff on the FCR Inventory (FCRI) severity subscale at screening. Participants were randomly assigned at a one-to-one ratio to either five face-to-face sessions of ConquerFear (attention training, metacognitions, acceptance/mindfulness, screening behavior, and values-based goal setting) or an attention control (Taking-it-Easy relaxation therapy). Participants completed questionnaires at baseline (T0), immediately post-therapy (T1), and 3 (T2) and 6 months (T3) later. The primary outcome was FCRI total score. Results Of 704 potentially eligible survivors from 17 sites and two online databases, 533 were contactable, of whom 222 (42%) consented; 121 were randomly assigned to intervention and 101 to control. Study arms were equivalent at baseline on all measured characteristics. ConquerFear participants had clinically and statistically greater improvements than control participants from T0 to T1 on FCRI total ( P < .001) and severity subscale scores ( P = .001), which were maintained at T2 ( P = .017 and P = .023, respectively) and, for FCRI total only, at T3 ( P = .018), and from T0 to T1 on three FCRI subscales (coping, psychological distress, and triggers) as well as in general anxiety, cancer-specific distress (total), and mental quality of life and metacognitions (total). Differences in FCRI psychological distress and cancer-specific distress (total) remained significantly different at T3.

Conclusion: This randomized trial demonstrated efficacy of ConquerFear compared with attention control (Taking-it-Easy) in reduction of FCRI total scores immediately post-therapy and 3 and 6 months later and in many secondary outcomes immediately post-therapy. Cancer-specific distress (total) remained more improved at 3- and 6-month follow-up.

Venom from Cuban Blue Scorpion has tumor activating effect in hepatocellular carcinoma.[Erratum appears in Sci Rep. 2017 Dec 22;7:46920; PMID: 29271404]

Abstract

Complementary and alternative medicine (CAM) is the term used to describe many kinds of products, practices, and systems that are not part of conventional medicine. Cancer patients usually do everything they can to combat the disease, manage its symptoms, and cope with the side effects of treatment. Unfortunately, patients who use CAM underestimate the risk of interaction with cancer therapy or worse they omit conventional therapy thus reducing the possibility of cancer remission. Herein we analyzed the effects of Vidatox 30 CH (venom extracted from the Junceus Rhopalurus scorpion) on hepatocellular carcinoma (HCC), the second leading cause of cancer-related deaths. We found out that Vidatox increases HCC proliferation and invasion whereas it does not seem to interact with sorafenib, the orally active multikinase inhibitor approved for the treatment of advanced hepatocellular carcinoma. Our results suggest that the concentration of Vidatox used in the present study has not anti-neoplastic effects and care must be taken in hiring Vidatox in patients with HCC.

Title

Mindfulness-Based Cognitive Therapy for Cancer Patients Delivered via Internet: Qualitative Study of Patient and Therapist Barriers and Facilitators.

Source

Journal of Medical Internet Research. 19(12):e407, 2017 Dec 18.

Abstract

BACKGROUND: The number of patients living with cancer is growing, and a substantial number of patients suffer from psychological distress. Mindfulness-based interventions (MBIs) seem effective in alleviating psychological distress. Unfortunately, several cancer patients find it difficult, if not impossible, to attend a group-based course. Internet-based MBIs (eMBIs) such as Internet-based mindfulness-based cognitive therapy (eMBCT) may offer solutions. However, it is yet to be studied what facilitators and barriers cancer patients experience during eMBCT.

OBJECTIVE: This study aimed to explore facilitators and barriers of individual asynchronous therapist-assisted eMBCT as experienced by both patients and therapists.

METHODS: Patients with heterogeneous cancer diagnoses suffering from psychological distress were offered eMBCT. This 9-week intervention mirrored the group-based MBCT protocol and included weekly asynchronous written therapist feedback. Patients were granted access to a website that contained the eMBCT protocol and a secured inbox, and they were asked to practice and fill out diaries on which the therapist provided feedback. In total, 31 patients participated in an individual posttreatment interview on experienced facilitators and barriers during eMBCT. Moreover, eight therapists were interviewed. The data were analyzed with qualitative content analysis to identify barriers and facilitators in eMBCT.

RESULTS: Both patients and therapists mentioned four overarching themes as facilitators and barriers: treatment setting (the individual and Internet-based nature of the treatment), treatment format (how the treatment and its guidance were organized and delivered), role of the therapist, and individual patient characteristics.

CONCLUSIONS: The eMBCT provided flexibility in when, where, and how patients and therapists engage in MBCT. Future studies should assess how different eMBCT designs could further improve barriers that were found.

Title

Beliefs and Determinants of Use of Traditional Complementary/Alternative Medicine in Pediatric Patients Who Undergo Treatment for Cancer in South America.

Journal of Global Oncology. 3(6):701-710, 2017 Dec.

Abstract

Purpose: The use of traditional complementary/alternative medicine (TCAM) among children with cancer has been well documented. South America has a rich history of traditional healers and medicinal resources; however, little is known about the use of TCAM among children with cancer. We sought to investigate patterns, beliefs, and determinants of TCAM use among South American children with cancer.

Methods: A cross-sectional survey was administered to 199 children treated for cancer at institutions located in Buenos Aires, Argentina, and Montevideo, Uruguay. Participants were queried about the type of TCAM and strength of beliefs associated with its use. Logistic regression analysis was used to estimate the odds ratios with 95% CIs.

Results We found that the use of TCAM was common in both Argentina (47%) and Uruguay (76%). Variations in the forms of TCAM used were observed between the countries; however, both countries used TCAM primarily for supportive care. Mother's education, wealth index, and TCAM belief system were significant predictors of TCAM. Conclusion To our knowledge, this study is the first to report on the use of TCAM in pediatric oncology in South America. The study identifies several predictors of TCAM use, which may serve as target variables for educational and research initiatives. The finding that most families use TCAM for supportive care suggests that future efforts could evaluate the role of TCAM to enhance existing supportive care regimens, particularly in settings where access to conventional medications are limited.
