Improve the Ability to Control the Brain’s Activity with Prayer and Meditation

 

By John M. de Castro, Ph.D.

 

“You can sculpt your brain just as you’d sculpt your muscles if you went to the gym. Our brains are continuously being sculpted, whether you like it or not, wittingly or unwittingly.” – Ritchie Davidson

 

The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. For example, the brain area that controls the right index finger has been found to be larger in blind subjects who use braille than in sighted individuals.  Similarly, cab drivers in London who navigate the twisting streets of the city, have a larger hippocampus, which is involved in spatial navigation, than predefined route bus drivers. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits.

 

Prayer and meditation can be quite similar. It is possible that they can both produce changes to the brain. Since, both involve a degree of self-control, it is possible that they both change the brain to enhance self-control mechanisms. In today’s Research News article “Ability to Gain Control Over One’s Own Brain Activity and its Relation to Spiritual Practice: A Multimodal Imaging Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5442174/ ), Kober and colleagues studied the ability of meditation and prayer to alter the nervous system and improve self-control. They recruited healthy adults who reported either a low or a high frequency of prayer or meditation. They were measured for spirituality and religiousness, mindfulness and locus of control. In addition, the participants had their brains scanned with Magnetic Resonance Imaging (MRI).

 

The participants had their brain activity measured with an electroencephalogram (EEG). They were shown a display with three bars the height of which was determined by brain activity in the 4-7 hertz (Theta), 12-25 hertz (SMR- Sensory-motor rhythm), and 21-35 hertz (Beta) range respectively. They received rewards (points) whenever their SMR was above a prescribed threshold and both their Theta and Beta were below a certain threshold. In other words, whenever their EEG reflected a specific prescribed pattern. If the participant was able to increase their SMR and decrease their Theta and Beta rhythms over training, it indicated and ability to control their brain activity.

 

They found, not surprisingly, that the high frequency group had higher levels of religiosity and mindfulness than the low frequency group. Importantly, they found a significant difference in the groups in their ability to control their brains. In particular, they found that the high frequency of meditation or prayer group was able to significantly increase their SMR while decreasing their Theta and Beta rhythms over training, while the low frequency group was not. When asked about their mental strategies to control their brain waves, the high frequency group reported significantly more “doing nothing”, similar to meditating or praying, than the low frequency group. Hence, the group who meditated and prayed often showed an ability to control their brains activity by employing a meditative strategy.

 

These are striking results. It has been known that with reward (biofeedback) people could learn to change their brain activity. But, it has never been shown before that people who prayed or meditated often would be significantly better at it than those who didn’t. The high frequency group is “assumed to be experts in focusing attention on inner states and self-referential processes.” This suggests that focused meditative practice improves the individual’s ability to control their brain activity. In other words, spiritual practice made them better at “doing nothing” and preventing thoughts from disrupting control of brain activity.

 

So, improve the ability to control the brain’s activity with prayer and meditation.

 

“The idea that there’s something specific about religious practices that changes your brain is just ridiculous. Everything changes your brain. Your brain is changing now, as is mine, as we’re having this conversation. There’s nothing special or magical about engaging in religious practices and showing certain changes in brain structure or function.” – Richard Sloan

Abstract

Spiritual practice, such as prayer or meditation, is associated with focusing attention on internal states and self-awareness processes. As these cognitive control mechanisms presumably are also important for neurofeedback (NF), we investigated whether people who pray frequently (N = 20) show a higher ability of self-control over their own brain activity compared to a control group of individuals who rarely pray (N = 20). All participants underwent structural magnetic resonance imaging (MRI) and one session of sensorimotor rhythm (SMR, 12–15 Hz) based NF training. Individuals who reported a high frequency of prayer showed improved NF performance compared to individuals who reported a low frequency of prayer. The individual ability to control one’s own brain activity was related to volumetric aspects of the brain. In the low frequency of prayer group, gray matter volumes in the right insula and inferior frontal gyrus were positively associated with NF performance, supporting prior findings that more general self-control networks are involved in successful NF learning. In contrast, participants who prayed regularly showed a negative association between gray matter volume in the left medial orbitofrontal cortex (Brodmann’s area (BA) 10) and NF performance. Due to their regular spiritual practice, they might have been more skillful in gating incoming information provided by the NF system and avoiding task-irrelevant thoughts.

Improve Physical and Psychological Well-Being with Cancer with Yoga

Improve Physical and Psychological Well-Being with Cancer with Yoga

 

By John M. de Castro, Ph.D.

 

“For those enduring chemotherapy and radiation, yoga for cancer provides a means to strengthen the body, boost the immune system, and produce a much-sought-after feeling of well-being. For those recovering from surgery, such as that for breast cancer, yoga can help restore motion and flexibility in a gentle, balanced manner.” – Yoga U

 

Receiving a diagnosis of cancer has a huge impact on most people. Feelings of depression, anxiety, and fear are very common and are normal responses to this life-changing and potentially life-ending experience. These feeling can result from changes in body image, changes to family and work roles, feelings of grief at these losses, and physical symptoms such as pain, nausea, or fatigue. People might also fear death, suffering, pain, or all the unknown things that lie ahead. So, coping with the emotions and stress of a cancer diagnosis is a challenge and there are no simple treatments for these psychological sequelae of cancer diagnosis.

 

But cancer diagnosis is not necessarily a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly increasing. It is estimated that 15 million adults and children with a history of cancer are alive in the United States today. But, surviving cancer carries with it a number of problems. “Physical, emotional, and financial hardships often persist for years after diagnosis and treatment. Cancer survivors are also at greater risk for developing second cancers and other health conditions.” National Cancer Survivors Day.

 

Mindfulness training has been shown to help with cancer recovery and help to alleviate many of the residual physical and psychological symptoms, including stress,  sleep disturbance, and anxiety and depression. In today’s Research News article “Yoga into cancer care: A review of the evidence-based research.” (See summary below or view the full text of the study at: http://www.ijoy.org.in/article.asp?issn=0973-6131;year=2018;volume=11;issue=1;spage=3;epage=29;aulast=Agarwal), Agarwal and Maroko-Afek review and summarize the published research literature on the effects of yoga practice on the physical and psychological symptoms of cancer diagnosis. They found 138 published studies with patients suffering from cancer and cancer treatment-related symptoms and side effects.

 

They found that yoga practice had widespread positive benefits for the psychological state and quality of life of the patients including reductions in anxiety, depression, anger, stress, PTSD symptoms, fear of reoccurrence, delirium, memory and concentration problems, and increases in self-esteem and social function. They also found that the literature demonstrated that yoga practice reduced a wide variety of physical symptoms of cancer or cancer treatment, including cardiovascular and pulmonary problems, inflammation, sleep and sexual dysfunctions, urinary and bladder problems, and skin and hair problems.

 

Hence, the published research makes a compelling case for the addition of yoga practice to the usual treatment of cancer. It is a safe, effective, and inexpensive treatment, with profound benefits for the psychological and physical health and quality of life of cancer patients.

 

So, improve physical and psychological well-being with cancer with yoga.

 

“Yoga for cancer patients—what better way to manage anxiety, gain strength, increase flexibility, and create feelings of well-being! A growing body of research points to the potential of yoga for supporting cancer patients, both during and after treatment.” – Tari Prinster

Abstract

To cope with cancer and its treatment-related side effects and toxicities, people are increasingly using complementary and alternative medicine (CAM). Consequently, integrative oncology, which combines conventional therapies and evidence-based CAM practices, is an emerging discipline in cancer care. The use of yoga as a CAM is proving to be beneficial and increasingly gaining popularity. An electronic database search (PubMed), through December 15, 2016, revealed 138 relevant clinical trials (single-armed, nonrandomized, and randomized controlled trials) on the use of yoga in cancer patients. A total of 10,660 cancer patients from 20 countries were recruited in these studies. Regardless of some methodological deficiencies, most of the studies reported that yoga improved the physical and psychological symptoms, quality of life, and markers of immunity of the patients, providing a strong support for yoga’s integration into conventional cancer care. This review article presents the published clinical research on the prevalence of yoga’s use in cancer patients so that oncologists, researchers, and the patients are aware of the evidence supporting the use of this relatively safe modality in cancer care.

Virtual Reality Enhances Meditative Experience

Virtual Reality Enhances Meditative Experience

 

By John M. de Castro, Ph.D.

 

“It seems that a technology that pries your eyes and ears wide open to absorb as much sensory input as possible is working at cross-purposes with a discipline that asks you to forgo distraction, to close your eyes and direct your attention inward.” – Michael Gollust

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of illnesses. It appears to be beneficial across ages, from children to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. The breadth and depth of benefits is unprecedented. There is no other treatment or practice that has been shown to come anyway near the range of mindfulness’ positive benefits. With impacts so great it is important to know how to promote the development of mindfulness even in individuals who dislike or avoid the discipline of practice.

 

Technology has recently been applied to training in mindfulness. Indeed, mindfulness training carried out completely on-line has been shown to be effective for as number of conditions. But, now virtual reality (VR) devices are improving and becoming readily available. Previously it has been shown the virtual reality (VR) can be helpful in treating phobias. and Borderline Personality Disorder (BPD). But, can VR enhance the development of mindfulness?

 

In today’s Research News article “Meditation experts try Virtual Reality Mindfulness: A pilot study evaluation of the feasibility and acceptability of Virtual Reality to facilitate mindfulness practice in people attending a Mindfulness conference.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5699841/ ), Navarro-Haro and colleagues had mindfulness experts who were attending a conference on mindfulness evaluate a Virtual Reality system that was designed to enhance the instructions of Dialectical Behavioral Therapy (DBT). They had the experts wear a VR helmet that presented a scene of floating “down a calm 3D computer generated virtual river while listening to digitized DBT mindfulness skills training instructions.” They listened to one of three 10-minute DBT instructions on “Wise Mind, Observing Sound, or Observing visuals.” Before and after the VR experience they were measured for mindfulness, state of presence, their emotional state, including happiness, sadness, anger, surprise, anxiety, relax/calm vigor/energy, previous experience with technologies and the acceptability of the method.

 

They found that in comparison to their pre-VR state, after the session the participants had significantly higher levels of mindfulness and relaxation and lower levels of sadness, anger, and anxiety. The system was acceptable as the participants gave high ratings to it and the experience. This acceptability was also significantly correlated with the changes in emotions. These results suggest that in the eyes of experts on mindfulness, using Virtual Reality to enhance mindfulness instruction was a good thing and made them feel more mindful and emotionally better.

 

This is a good start. Of course, the next step will be to determine if VR is acceptable and can enhance mindfulness instruction in individuals who were not adept at, or practiced mindfulness. Additionally, this was an extremely short-term experience. It will be necessary to determine the effects of longer-term use of VR. Since, mindfulness training involves quieting the mind, it is possible that the VR stimulus environment may work counter to the goals of mindfulness practice. Finally, it will be necessary to try VR enhanced mindfulness training with individuals with physical and/or psychological problems.

 

Nevertheless, VR is an interesting technology that has been shown to help in treating some forms of psychological issues; phobias. and Borderline Personality Disorder (BPD) and holds promise for further applications. It may be a method that can help train mindfulness even in resistant individuals.

 

“As I continued my exploration of this virtual world, at some point I noticed my mind had gone completely still. The monkey-mind, that great enemy of meditation, mindfulness, and really, of life, had all but vanished. I’d gone from zero to zen and the stillness that followed was glorious.’ – Mind Prana

Abstract

Regular mindfulness practice benefits people both mentally and physically, but many populations who could benefit do not practice mindfulness. Virtual Reality (VR) is a new technology that helps capture participants’ attention and gives users the illusion of “being there” in the 3D computer generated environment, facilitating sense of presence. By limiting distractions from the real world, increasing sense of presence and giving people an interesting place to go to practice mindfulness, Virtual Reality may facilitate mindfulness practice. Traditional Dialectical Behavioral Therapy (DBT®) mindfulness skills training was specifically designed for clinical treatment of people who have trouble focusing attention, however severe patients often show difficulties or lack of motivation to practice mindfulness during the training. The present pilot study explored whether a sample of mindfulness experts would find useful and recommend a new VR Dialectical Behavioral Therapy (DBT®) mindfulness skills training technique and whether they would show any benefit. Forty four participants attending a mindfulness conference put on an Oculus Rift DK2 Virtual Reality helmet and floated down a calm 3D computer generated virtual river while listening to digitized DBT® mindfulness skills training instructions. On subjective questionnaires completed by the participants before and after the VR DBT® mindfulness skills training session, participants reported increases/improvements in state of mindfulness, and reductions in negative emotional states. After VR, participants reported significantly less sadness, anger, and anxiety, and reported being significantly more relaxed. Participants reported a moderate to strong illusion of going inside the 3D computer generated world (i.e., moderate to high “presence” in VR) and showed high acceptance of VR as a technique to practice mindfulness. These results show encouraging preliminary evidence of the feasibility and acceptability of using VR to practice mindfulness based on clinical expert feedback. VR is a technology with potential to increase computerized dissemination of DBT® skills training modules. Future research is warranted.

Reduce Genetic Markers of Inflammation with Yoga

Reduce Genetic Markers of Inflammation with Yoga

 

By John M. de Castro, Ph.D.

 

“Yoga is fantastic for decreasing stress levels, and research has also shown that those who practice yoga regularly have higher levels of leptin and adiponectin in their bodies. Both of these natural chemicals work to alleviate inflammation in the body.” – Julie Montagu

 

The immune system is designed to protect the body from threats like stress, infection, injury, and toxic chemicals. One of its tools is the Inflammatory response. This response works quite well for short-term infections and injuries. But when inflammation is protracted and becomes chronic, it can itself become a threat to health. It can produce autoimmune diseases such as colitis, Chron’s disease, arthritis, heart disease, increased cancer risk, lung disease, sleep disruption, gum disease, decreased bone health, psoriasis, and depression. Needless to say, chronic inflammation can create major health problems. Indeed, the presence of chronic inflammation is associated with reduced longevity. So, it is important for health to control the inflammatory response, allowing it to do its job in fighting off infection but reducing its activity when no real external threat is apparent.

 

Of course, it is far better to prevent chronic inflammation in the first place than to treat it later. Mind-body techniques such as yoga, Tai Chi and meditation have been shown to adaptively reduce the inflammatory response. In today’s Research News article “Preliminary indications of the effect of a brief yoga intervention on markers of inflammation and DNA methylation in chronically stressed women.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5290356/ ), Harkess and colleagues recruited women who were psychologically distressed and randomly assigned them to either a wait-list or to receive 8 weeks of twice a week for 1-hour yoga practice. Blood samples were obtained from the participants and measures of psychological distress, perceived stress, and positive and negative emotions, before and after the practice and 1 month later. Blood was assayed for concentrations of cytokines (IL-6, TNF), DNA methylation for immune candidates IL-6, CRP, and TNF.

 

They found that there were trends for improvements in all of the inflammation markers, but most were not significant. But, there was a significant improvement in the marker of DNA methylation in the region of Tumor Necrosis Factor, TNF. DNA methylation have been associated with poor physical health, and high levels of inflammation. So, the reduction in DNA methylation in the TNF region suggests a reduction in chronic inflammation. This may suggest that yoga practice might improve general health by reducing chronic inflammation.

 

It is reasonable to conclude that although there were many suggestive results, this pilot trial did not have sufficient statistical power to detect significant differences for most markers. Also, more extensive yoga practice beyond the 16 sessions in this trial, might produce more robust effects. In addition, the pilot trial lacked an active control condition. So, a number of sources of bias could be responsible for the results. The results, however, are sufficiently interesting and suggestive that they support conducting a larger randomized controlled clinical trial with an active control, perhaps aerobic exercise on the effectiveness of yoga practice on genetic markers of inflammation.

 

“There’s evidence that such “mind-body practices” dampen the activity of genes associated with inflammation – essentially reversing molecular damage caused by stress.” – Jo Marchant

Abstract

Yoga is associated with reduced stress and increased well-being, although the molecular basis for these benefits is not clear. Mounting evidence implicates the immune response, with current studies focused on protein immune markers (such as cytokines) in clinical populations. To explore the molecular impact, this pilot study uses a subsample (n=28) from a randomised waitlist control trial investigating the impact of an 8-week yoga intervention in a community population of women reporting psychological distress (N=116). We measured interleukin-6 (IL-6), tumour necrosis factor (TNF) and C-reactive protein (CRP) protein levels, and the DNA methylation of these genes and the global indicator, LINE-1. Correlations between these and psychological variables were explored, identifying moderate correlations with CRP protein levels, and methylation of IL-6, CRP and LINE-1. Many cytokine samples were below detection, however a Mann–Whitney U demonstrated a trend of moderate between-group effect for elevated IL-6 in the yoga group. Methylation analyses applied cross-sectional and non-controlled longitudinal analyses. Waist-to-height ratio and age were covaried. We demonstrated reduced methylation of the TNF region in the yoga group relative to the waitlist control group. No other genes demonstrated a significant difference. Longitudinal analysis further supported these results. This study is one of the first to explore yoga and immunological markers in a non-clinical population, and is the first study to explore DNA methylation. These findings indicate that further research into molecular impact of yoga on markers of immune function is warranted, with larger studies required.

Reduce Depression During and After Pregnancy with Mindfulness

Reduce Depression During and After Pregnancy with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness practice, when attention increases in one area of life, the awareness expands in many other areas, as well. A mother who is able to care for and attend to her own vulnerabilities will have much more access to those very same skills as a parent.” – Sonya Dimidjian

 

The perinatal period, from the onset of pregnancy to the end of the infants first year, is a time of intense physiological and psychological change in both the mother and the infant. Anxiety, depression, and fear are quite common during pregnancy. More than 20 percent of pregnant women have an anxiety disorder, depressive symptoms, or both during pregnancy. It is difficult to deal with these emotions under the best of conditions but in combinations with the stresses of pregnancy can turn what could be a joyous experience of creating a human life into a horrible worrisome, torment. The psychological health of pregnant women has consequences for fetal development, birthing, and consequently, child outcomes. Depression during pregnancy is associated with premature delivery and low birth weight. Hence, it is clear that there is a need for methods to treat depression during and after pregnancy.

 

Since, many drugs can affect the fetus, non-pharmacological treatments for depression are preferable. Mindfulness training has been shown to improve anxiety and depression normally and to relieve maternal anxiety and depression during pregnancy. Mindfulness-Based Cognitive Therapy (MBCT) was specificly developed to treat depression and consists of mindfulness training and Cognitive Behavioral Therapy (CBT). During therapy the patient is trained to investigate and alter aberrant thought patterns underlying depression. So, it would make sense to further study the effectiveness of MBCT for depression during the perinatal period.

 

In today’s Research News article “Staying Well during Pregnancy and the Postpartum: A Pilot Randomized Trial of Mindfulness Based Cognitive Therapy for the Prevention of Depressive Relapse/Recurrence.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5718345/ ), Dimidjian and colleagues recruited pregnant women with Major Depressive Disorder and randomly assigned them to receive either treatment as usual or to Mindfulness-Based Cognitive Therapy (MBCT). MBCT was modified for pregnant women and administered for 2 hours, once a week, for 8 weeks and home practice was assigned. The women were measured for depression before and after treatment and at 1 and 6 months after birth.

 

In regards to depression, they found that relapse rates for depression over the 6-month follow-up period were significantly lower for the MBCT group; 18% vs. 50% for treatment as usual. In addition, the MBCT group had significantly lower levels of depression after treatment. Although the differences were not significant the MBCT group took fewer antidepressant medications and had fewer visits for therapy. A goal of this pilot research study was to assess the acceptability of the program and compliance with its requirements. They found that 89% completed the MBCT program and home practice occurred on over 70% of the available days. In addition, the women reported a high degree of satisfaction with the program.

 

These are impressive results for a pilot study and should provide the encouragement to perform a large randomized controlled clinical trial with an active control group. The results suggest that MBCT treatment is a safe and effective treatment for perinatal depression and has high acceptability and compliance among pregnant women. Hence it is a promising treatment for perinatal depression.

 

So, reduce depression during and after pregnancy with mindfulness.

 

“Not only does cultivating moment-to-moment awareness of thoughts and surroundings seem to help pregnant women keep their stress down and their spirits up—benefits that are well-documented among other groups of people—it may also lead to healthier newborns with fewer developmental problems down the line.” – Kira Newman

Study Summary

 

Dimidjian, S., Goodman, S. H., Felder, J., Gallop, R., Brown, A. P., & Beck, A. (2016). Staying Well during Pregnancy and the Postpartum: A Pilot Randomized Trial of Mindfulness Based Cognitive Therapy for the Prevention of Depressive Relapse/Recurrence. Journal of Consulting and Clinical Psychology, 84(2), 134–145. http://doi.org/10.1037/ccp0000068

Abstract

Objective

Clinical decision-making regarding the prevention of depression is complex for pregnant women with histories of depression and their healthcare providers. Pregnant women with histories of depression report preference for non-pharmacological care, but few evidence-based options exist. Mindfulness-based cognitive therapy has strong evidence in the prevention of depressive relapse/recurrence among general populations and indications of promise as adapted for perinatal depression (MBCT-PD). With a pilot randomized clinical trial, our aim was to evaluate treatment acceptability and efficacy of MBCT-PD relative to treatment as usual (TAU).

Methods

Pregnant adult women with depression histories were recruited from obstetrics clinics at two sites and randomized to MBCT-PD (N= 43) or TAU (N=43). Treatment acceptability was measured by assessing completion of sessions, at-home practice, and satisfaction. Clinical outcomes were interview-based depression relapse/recurrence status and self-reported depressive symptoms through 6-months postpartum.

Results

Consistent with predictions, MBCT-PD for at-risk pregnant women was acceptable based on rates of completion of sessions and at-home practice assignments, and satisfaction with services was significantly higher for MBCT-PD than TAU. Moreover, at-risk women randomly assigned to MBCT-PD reported significantly improved depressive outcomes compared to participants receiving TAU, including significantly lower rates of depressive relapse/recurrence and lower depressive symptom severity during the course of the study.

Conclusions

MBCT-PD is an acceptable and clinically beneficial program for pregnant women with histories of depression; teaching the skills and practices of mindfulness meditation and cognitive behavioral therapy during pregnancy may help to reduce the risk of depression during an important transition in women’s lives.

Public Health Significance Statement

This study’s findings support MBCT-PD as a viable non-pharmacological approach to preventing depressive relapse/recurrence among pregnant women with histories of depression.

Improve Cancer Survivor Quality of Life with Exercise or Mindfulness

Improve Cancer Survivor Quality of Life with Exercise or Mindfulness

 

By John M. de Castro, Ph.D.

 

“One of the main reasons people with cancer use meditation is to help them to feel better. Meditation can reduce anxiety and stress. It might also help control problems such as: pain, difficulty sleeping, tiredness, feeling sick, high blood pressure.” – Cancer Research UK

 

Receiving a diagnosis of cancer has a huge impact on most people. Feelings of depression, anxiety, and fear are very common and are normal responses to this life-changing and potentially life-ending experience. These feeling can result from changes in body image, changes to family and work roles, feelings of grief at these losses, and physical symptoms such as pain, nausea, or fatigue. People might also fear death, suffering, pain, or all the unknown things that lie ahead. So, coping with the emotions and stress of a cancer diagnosis is a challenge and there are no simple treatments for these psychological sequelae of cancer diagnosis.

 

But cancer diagnosis is not necessarily a death sentence. Over half of the people diagnosed with cancer are still alive 10 years later and this number is rapidly increasing. It is estimated that 15 million adults and children with a history of cancer are alive in the United States today. But, surviving cancer carries with it a number of problems. “Physical, emotional, and financial hardships often persist for years after diagnosis and treatment. Cancer survivors are also at greater risk for developing second cancers and other health conditions.” National Cancer Survivors Day.

 

Mindfulness training has been shown to help with cancer recovery and help to alleviate many of the residual physical and psychological symptoms, including stress,  sleep disturbance, and anxiety and depression. In today’s Research News article “Review of systematic reviews of non-pharmacological interventions to improve quality of life in cancer survivors.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5719270/ ), Duncan and colleagues summarize the published scientific reviews of randomized controlled trials on the effects of non-drug interventions on the quality of life of adult cancer survivors. The interventions included fell into a number of categories including physical (e.g. aerobic exercise, yoga), psychological education,  peer support, and mind-body therapies (Mindfulness-Based Stress Reduction (MBSR), cognitive behavioral therapy (CBT), psychotherapy, relaxation training).

 

They discovered 21 published reviews of 362 randomized controlled trials. They found that the literature supported the efficacy of aerobic exercise, yoga, cognitive behavioral therapy (CBT), and Mindfulness-Based Stress Reduction (MBSR) in improving the quality of life in cancer survivors. Hence, published scientific randomized controlled trials of non-drug treatment approaches demonstrate that the quality of life of cancer survivors can be improved with exercise, CBT, and mindfulness practices such as MBSR and yoga.

 

It was not reported how these practices might improve quality of life in cancer survivors. But, it can be speculated that because cancer treatments are physically demanding and of themselves produce physical debilitation, that exercise is a useful countermeasure to help overcome the physical losses occurring in treatment. It can also be speculated that mindfulness training may be helpful by improving the survivor’s ability to regulate the emotions produced by a cancer diagnosis and its treatment. These include anxiety, depression, fear, catastrophizing etc. By improving the ability to feel these emotions but react to them adaptively and thereby not amplifying them, the survivors may help to improve their emotional well-being and as a result their quality of life.

 

So, improve cancer survivor quality of life with exercise or mindfulness.

 

“We already know that psychosocial interventions like mindfulness meditation will help you feel better mentally, but now for the first time we have evidence that they can also influence key aspects of your biology,” – Linda Carlson

Study Summary

 

Duncan, M., Moschopoulou, E., Herrington, E., Deane, J., Roylance, R., Jones, L., … Bhui, K. (2017). Review of systematic reviews of non-pharmacological interventions to improve quality of life in cancer survivors. BMJ Open, 7(11), e015860. http://doi.org/10.1136/bmjopen-2017-015860

 

Strengths and limitations of this study

  • This is a systematic review of reviews and evidence synthesis of non-pharmacological interventions in cancer survivors.
  • Longer term studies are needed and studies of greater methodological quality that adopt similar reporting standards.
  • Definitions of survivor varied and more studies are needed for different types of cancer, and specifically for patients who have poor quality of life.
  • More studies are needed that investigate educational, online and multidisciplinary team-based interventions.
  • This review has some limitations in the methodology. Studies not in English and grey literature were not included. This was a review of reviews: we did not review individual studies focused on specific cancers or stage, and we did not reassess the quality of the primary studies included in each review.

 

Abstract

Objectives

Over two million people in the UK are living with and beyond cancer. A third report diminished quality of life.

Design

A review of published systematic reviews to identify effective non-pharmacological interventions to improve the quality of life of cancer survivors.

Data sources

Databases searched until May 2017 included PubMed, Cochrane Central, EMBASE, MEDLINE, Web of Science, the Cumulative Index to Nursing and Allied Health Literature, and PsycINFO.

Study selection

Published systematic reviews of randomised trials of non-pharmacological interventions for people living with and beyond cancer were included; included reviews targeted patients aged over 18. All participants had already received a cancer diagnosis. Interventions located in any healthcare setting, home or online were included. Reviews of alternative therapies or those non-English reports were excluded. Two researchers independently assessed titles, abstracts and the full text of papers, and independently extracted the data.

Outcomes

The primary outcome of interest was any measure of global (overall) quality of life.

Analytical methods

Quality assessment assessing methdological quality of systematic reviews (AMSTAR) and narrative synthesis, evaluating effectiveness of non-pharmacological interventions and their components.

Results

Of 14 430 unique titles, 21 were included in the review of reviews. There was little overlap in the primary papers across these reviews. Thirteen reviews covered mixed tumour groups, seven focused on breast cancer and one focused on prostate cancer. Face-to-face interventions were often combined with online, telephone and paper-based reading materials. Interventions included physical, psychological or behavioural, multidimensional rehabilitation and online approaches. Yoga specifically, physical exercise more generally, cognitive behavioural therapy (CBT) and mindfulness-based stress reduction (MBSR) programmes showed benefit in terms of quality of life.

Conclusions

Exercise-based interventions were effective in the short (less than 3–8 months) and long term. CBT and MBSR also showed benefits, especially in the short term. The evidence for multidisciplinary, online and educational interventions was equivocal.

The Noble Eightfold Path: Right Intentions

The Noble Eightfold Path: Right Intentions

 

By John M. de Castro, Ph.D/

 

“And what is right intention? It is the release of chasing after of fleeting pleasures, the release of the intention of malice, the release of the intention of doing harm.” – Buddha

 

“Developing wholesome intentions begins a natural process of building a foundation of ethics, and mindfulness is the tool that helps you see what you need to work on, what you need to let go of, and to act responsibly instead of reacting harshly or foolishly.” – Dana Nourie

 

The Buddha’s path to enlightenment, the Noble Eightfold Path consists of “Right View, Right Intentions, Right Speech, Right Actions, Right Livelihood, Right Effort, Right Mindfulness and Right Concentration.” – Buddha. In a previous post

https://www.facebook.com/ContemplativeStudiesCenter/photos/a.628903887133541.1073741828.627681673922429/1206634286027162/?type=3&theater

The first component of the Noble Eightfold Path, “Right View” was discussed. It is intimately tied together with “Right Intentions” as there can be no “Right Intentions” without first seeing existence clearly and with discernment. Only, then can “Right Intentions” be established. In fact, “Right View” provides the thought processes necessary to set future directions, “Right Intentions”. This an instance of how all of the components of the Noble Eightfold Path are interconnected and depend upon one another.

 

Intentions are the drivers of actions. They involve thoughtful directions to produce wholesome outcomes. The simplest way to look at “Right Intentions” is as the aspiration to create greater happiness, wisdom, and well-being, and relieve suffering in ourselves and others. This is where “Right View” comes in and provides the wisdom to discern which aspirations are likely to produce wholesome outcomes. We may start the day with the intent to help others in need and discern that donating an hour of our time to volunteer work at a homeless shelter would likely produce greater happiness, wisdom, and well-being, and relieve suffering. This is right intention at work, derived from “Right View” and producing “Right Actions.” It is critical that the intention is wholesome. The same action, donating time, might be motivated by a desire to appear kind and generous to others, to obtain a tax deduction, or to impress a romantic interest who also volunteers. All of these are intentions governed by desires and are not part of the path. So, the action is important but only to the extent that it is motivated by a “Right Intentions.”

 

The Buddha taught that there were three kinds of “Right Intentions”: the intention of renunciation, the intention of good will, and the intention of harmlessness. The intention of renunciation is to eliminate attachments to the desires which normally drive our actions. This does not mean that we don’t aspire to acquire things, satisfy needs, or experience pleasures. Rather, it mandates the release of attachment to the desire. We still like to eat a good meal, well prepared and tasty. Experiencing this is simply experiencing what is. The need to eat is a healthy part of maintaining well-being and enjoyment of the sensory pleasure of eating is a healthy experience, provided that the goal (intention) is not to acquire these experiences and pursue them in search of happiness. When we are driven by seeking sensory pleasure, we will experience momentary happiness, but inevitably it will lead to suffering as the happiness cannot be maintained. The pleasure of fine dining quickly dissipates and we feel unfulfilled until we can have another fine dining experience, which again leads to unsatisfactoriness, suffering. The intention of renunciation derives from understanding that the intention to find satisfaction by fulfilling desires is not the way to create greater happiness, wisdom, and well-being, but a way to increase suffering. So, we renounce the drive to fulfill the desire and become unattached. This will free us from the endless cycle of desire and suffering.

 

The intention of good will is also an intention toward loving kindness. It is a deep inner good will to all living beings including the self. This is not sensual love or love given in expectation of a return or a gain. It is not limited to certain people or even certain species. It is not contingent on particular behaviors, attitudes, or likeability. It is rather a pure kindness and wish for well-being of all. It is a recognition of suffering in self and others and deep compassion for that suffering and the intention to work for its relief. The intention of good will derives from understanding that all sentient beings suffer, but that the suffering can be eliminated. It expresses a deep compassion and understanding of this suffering and it energizes actions to relieve the suffering in self in others.

 

The intention of harmlessness is a broad intention to not cause pain, loss, or destruction to any sentient being, humans and non-human animals included. This can be quite difficult to accomplish as our actions can have rippling consequences that somewhere down the chain of causation produce harm. We can’t always know or discern what might happen, so the intention is critical. In donating time to work at a homeless shelter we may drive our car to the shelter. The exhaust contributes carbon to the atmosphere, contributing to global warming, harming all sentient beings. During the drive a squirrel might dash in front of the car and get struck. The discernment is difficult and “Right View” is critical to the intention of harmlessness.

 

A little thought regarding the implications of the intention of harmlessness will lead to perhaps adopting a vegetarian diet, as eating flesh creates harm to sentient beings. But, even a vegetarian diet creates harm. In growing vegetables, many sentient beings such as rodents, reptiles, and birds are inevitably destroyed. Additionally, cooking the vegetables releases carbon into the atmosphere. So, it is important to understand that we can never be completely harmless while we’re alive. The important point is to set the intention to do the least harm possible while still maintaining our health, doing good, and making a living.

 

It should be clear from all of this that “Right Intention” is a critical driver for actions along the Eightfold Path. Without intentions of renunciation, good will, and harmlessness we are rudderless. The “Right Intentions” are our moral compass. As such, they are key to wholesome living and progress on the path.

 

So, set “Right Intentions” and move forward on the Eightfold Path.

 

“The largest pool of untapped resources in the world today is humans’ good intentions that don’t translate into action.” ~ Lloyd Nimetz

Reduce Inflammation in elderly Women with Yoga

Reduce Inflammation in elderly Women with Yoga

 

By John M. de Castro, Ph.D.

 

“Inflammaging has been associated with conditions like diabetes, heart disease, stress, depression, and a weakened immune system. Several recent studies suggest that yoga could slow the harmful physical effects of stress and inflammaging.” – Marylynn Wei

 

The immune system is designed to protect the body from threats like stress, infection, injury, and toxic chemicals. One of its tools is the Inflammatory response. This response works quite well for short-term infections and injuries. But when inflammation is protracted and becomes chronic, it can itself become a threat to health. It can produce autoimmune diseases such as colitis, Chron’s disease, arthritis, heart disease, increased cancer risk, lung disease, sleep disruption, gum disease, decreased bone health, psoriasis, and depression. Needless to say, chronic inflammation can create major health problems. Indeed, the presence of chronic inflammation is associated with reduced longevity. So, it is important for health to control the inflammatory response, allowing it to do its job in fighting off infection but reducing its activity when no real external threat is apparent.

 

Of course, it is far better to prevent chronic inflammation in the first place than to treat it later. Mind-body techniques such as yoga, Tai Chi and meditation have been shown to adaptively reduce the inflammatory response. Aging is associated with a decline in immune system function and therefore an increase in chronic inflammation. As a result, the elderly are particularly vulnerable to chronic inflammation. So, it would make sense to test the effectiveness of mindfulness practices in the levels of inflammation in the elderly.

 

In today’s Research News article “Elderly-customized hatha yoga effects on the vascular inflammation factors of elderly women.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5683994/ ), Kim and Ju Examined this issue by recruiting 14 healthy elderly women between the ages of 70 and 80 and randomly assigning 7 of the women to no treatment and 7 to receive a 10-week, 3 times per week for 60 minutes Hatha yoga program. The Hatha yoga poses were modified for the elderly performing many of the poses while sitting in a chair. Blood was drawn at the beginning and end of the program and assayed for inflammation markers of albumin, white blood cell count, fibrinogen, high sensitivity C-reactive protein, and erythrocyte sedimentation rate.

 

They found that there were no significant changes in the inflammation markers for the control group, but the Hatha yoga group showed significant changes signaling reduced inflammation. These changes included significantly increased albumin levels and decreased vascular inflammation markers of fibrinogen, high sensitivity C-reactive protein, and erythrocyte sedimentation rate. So, engaging in Hatha yoga practice appeared to reduce inflammation in these elderly women.

 

The results should be interpreted carefully as there was not an active control condition. So, it cannot be determined if the yoga practice per se was responsible for the improvements or simply any gentle exercise would produce comparable benefits. But, the fact that statistically significant findings were present with only 7 women in the yoga group is remarkable and suggests that the effects are robust. Future research should include men and have an active control condition, perhaps treadmill walking or similar gentle aerobic exercise.

 

So, reduce inflammation in elderly women with Yoga.

 

“There’s also good news for those of us who have a regular yoga practice. Several studies now report that a regular yoga practice brings down the levels of stress hormones that promote inflammation, lowers the levels of a number of pro-inflammatory molecules in the body and brings down inflammation that is beneficial in conditions like arthritis, reduces a subset of pro-inflammatory molecules called cytokines thereby relieving severe pain seen in diseases like fibromyalgia, and Inhibits inflammation that in turn weakens and even kills cancerous cells in people with cancer.” -Ram Rao

Abstract

[Purpose] The aim of this study was to examine the effects of the application of elderly-customized hatha yoga on the vascular inflammation factors of elderly women. [Subjects and Methods] This research was conducted with 14 elderly women, between 70 and 80 years old, divided into an elderly-customized hatha yoga group (n=7) and a control group (n=7). The application group participated in a hatha yoga program designed to be elderly-friendly for 10 weeks. At the end of the program, the vascular inflammation factors were measured, including the albumin, white blood cell count, fibrinogen, high sensitivity C-reactive protein (hs-CRP), and erythrocyte sedimentation rate (ESR). [Results] In the hatha yoga group, the albumin increased significantly after the application, when compared to the level before the application, while the fibrinogen, hs-CRP, and ESR decreased significantly. In the control group, the vascular inflammation factor levels before and after the application period were not significantly different. [Conclusion] Based on the results of this study, the application of elderly-customized hatha yoga created positive changes in the vascular inflammation factors of elderly women.

Improve the Emotion Regulation of High School Students with Mindfulness

Improve the Emotion Regulation of High School Students with Mindfulness

 

By John M. de Castro, Ph.D.

 

“A large part of being a human being is having social, emotional and attention skills and in the majority of schools I visit, we don’t actually teach kids how to pay attention or how to deal with their inner states in a healthy way. We just assume that they’ll learn them somewhere else.” – Patrick Cook-Deegan

 

It’s a normal human response to become anxious while being evaluated by others. In fact, the vast majority of students report that the stress and anxiety associated with being evaluated is greater than that produced by anything else in their lives. The majority of students are able to cope with the anxiety and perform on tests in spite of it. But, for a minority of students, somewhere around 16%-20%, the anxiety level is so high that it causes them to “freeze” on tests and markedly impair their performance. It is estimated that they perform 12 points lower, more than one letter grade, on average than students lower in anxiety. Counselling centers in colleges and universities report that evaluation anxiety is the most common complaint that they treat among students.

 

It has been demonstrated repeatedly that mindfulness counteracts anxiety and mindfulness training is an effective treatment for a variety of forms of anxiety. Mindfulness training has been shown to be effective for anxiety disorders in general and  in relieving test anxiety. Mindfulness-Based Stress Reduction (MBSR) is a classic program that includes three mindfulness techniques; meditation, body scan, and yoga. MBSR has been employed for years to successfully treat a myriad of psychological and medical conditions. But, it has not yet been tested for use to treat test anxiety.

 

In today’s Research News article “Effectiveness of mindfulness-based stress reduction on emotion regulation and test anxiety in female high school students.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5651652/ ),

Shahidi and colleagues recruited female High School students and randomly assigned them to a no-treatment control condition or to receive an 8-week, once a week for 90 minutes, program of Mindfulness-Based Stress Reduction (MBSR) with encouragement to practice at home. They were measured before and after training and 3-months later for test anxiety and emotion regulation.

 

They found that after the program and also 3-months later that the students who received MBSR had clinically significant 46% reductions in test anxiety. In addition, they showed significant improvement in emotion regulation including; blaming others, rumination/focus on thought, catastrophizing, putting into perspective, positive refocusing, positive reappraisal, acceptance, and refocus on planning. Only the self-blame strategy was not significantly affected by MBSR training. Hence, MBSR training for High School students produces a lasting relief of test anxiety and improves the ability to cope with emotions.

 

It should be mentioned that this study did not contain an active control condition. So, bias and contamination of the results may be present. Also, the study only tested female students, thus limiting generalization of the results. Future research should include a both males and females and a group receiving active alternative treatment, say exercise training. Regardless, the results suggest that MBSR training can help students cope with their emotions, including test anxiety. This would predict that there would be improved academic performance and less psychological problems in the trained students. This further suggests that MBSR training should be considered to be routinely employed for High School students.

 

So, improve the emotion regulation of high school students with mindfulness.

 

“Mindfulness practices help children improve their ability to pay attention, by learning to focus on one thing (e.g., breath, sound) while filtering out other stimuli. Mindfulness also provides kids with skills for understanding their emotions and how to work with them.” – Sarah Beach

Abstract

BACKGROUND:

Test anxiety is one of the most disabling disorders and annual school academic performance will affect millions of students. Hence, it needs attention and treatment. Therefore, this research aimed to examine the effectiveness of a mindfulness-based stress reduction (MBSR) therapy on emotion regulation and test anxiety of students and test the remaining effect of this treatment after 3 month.

METHODS:

Sample size of fifty participants randomly divided into experimental (MBSR) and control groups. The MBSR training interventions were implemented to the experimental group, in eight weekly sessions using MBSR manual by John Kabat-Zinn (2013). Participants in both groups were evaluated using the Test Anxiety Scale and the Cognitive Emotion Regulation Questionnaire. The study findings were analyzed using analysis of variance with repeated measures.

RESULTS:

The result shows that the MBSR program has had continuous significant effects on test anxiety (P< 000) and emotion regulation (P < 000) but was not significant only for the self-blame subscale (P = 0.126).

CONCLUSIONS:

The study results indicated that the effects of MBSR lasted through the follow-up, for both of these variables. Using the results of this study may be proposed school counselors use mindfulness to reduce the anxiety of their pupils.

Improve Cardiorespiratory Fitness with Tai Chi

Improve Cardiorespiratory Fitness with Tai Chi

By John M. de Castro, Ph.D.

 

“practicing Tai Chi Chuan regularly may delay the decline of cardiorespiratory function in older individuals. In addition, TCC may be prescribed as a suitable aerobic exercise for older adults.” – J.S. Lai

 

Cardiovascular disease is the number one killer, claiming more lives than all forms of cancer combined. “Heart disease is the leading cause of death for both men and women. About 610,000 people die of heart disease in the United States every year–that’s 1 in every 4 deaths. Every year about 735,000 Americans have a heart attack.” (Centers for Disease Control). A myriad of treatments has been developed for heart disease including a variety of surgical procedures and medications. In addition, lifestyle changes have proved to be effective including quitting smoking, weight reduction, improved diet, physical activity, and reducing stresses. Cardiac rehabilitation programs for patients recovering from a heart attack, emphasize these lifestyle changes. Unfortunately, for a variety of reasons, 60% of cardiac patients decline participation, making these patients at high risk for another attack.

 

Contemplative practices, such as meditation, tai chi, and yoga, have also been shown to be helpful for heart health. In addition, mindfulness practices have also been shown to be helpful for producing the kinds of other lifestyle changes needed such as smoking cessation, weight reduction and stress reduction.  Tai Chi and Qigong are ancient mindfulness practices involving slow prescribed movements. They are gentle and completely safe, can be used with the elderly and sickly, is inexpensive to administer, can be performed in groups or alone, at home or in a facility or even public park, and can be quickly learned. In addition, they can also be practiced in social groups without professional supervision. This can make it fun, improving the likelihood of long-term engagement in the practice. Since Tai Chi is both a mindfulness practice and an exercise, it may be an acceptable and effective treatment for cardiac patients.

 

In today’s Research News article “The Effect of Tai Chi on Cardiorespiratory Fitness for Coronary Disease Rehabilitation: A Systematic Review and Meta-Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5758591/ ), Yang and colleagues review, summarize and perform a meta-analysis of 5 published studies involving the application of Tai Chi practice for cardiac patients. Two studies were randomized controlled trials while 2 did not have a comparison (control) condition.

 

They report that the published studies found that Tai Chi practice produced significant improvement in the oxygen carrying capacity of the blood (VO2max) and was superior to light or moderate exercise but not different from intense exercise. Tai Chi practice also produced a significant improvement in peak heart rate in comparison to baseline and no exercise, but was inferior to intense exercise in this regard. Hence, there is evidence that Tai Chi practice can be of benefit to cardiac patients improving cardiorespiratory function.

 

The studies reviewed tended to have small samples or had week or nonexistent control conditions. So, conclusions must be tempered. The present summary, however, suggest that larger randomized controlled trials are justified. Tai Chi was not found to be as beneficial as intense exercise. But, intense exercise may be dangerous for cardiac patients. The attractiveness of the low intensity, low cost, convenient, and socially fun nature of Tai Chi practice makes it a good choice for cardiac patients.

 

So, improve cardiorespiratory fitness with Tai Chi.

 

“The slow and gentle movements of Tai Chi hold promise as an alternative exercise option for patients who decline traditional cardiac rehabilitation.” – Science Daily

Abstract

Background: Tai Chi that originated in China as a martial art is an aerobic exercise with low-to-moderate intensity and may play a role in cardiac rehabilitation. Aim: To systematically review the effect of Tai Chi on cardiorespiratory fitness for coronary disease rehabilitation. Methods: We performed a search for Chinese and English studies in the following databases: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese Biomedical Literature Database, China Knowledge Resource Integrated Database, Wanfang Data, and China Science and Technology Journal Database. The search strategy included terms relating to or describing Tai Chi and coronary disease, and there were no exclusion criteria for other types of diseases or disorders. Further, bibliographies of the related published systematic reviews were also reviewed. The searches, data extraction, and risk of bias (ROB) assessments were conducted by two independent investigators. Differences were resolved by consensus. RevMan 5.3.0 was used to analyze the study results. We used quantitative synthesis if the included studies were sufficiently homogeneous and performed subgroup analyses for studies with different control groups. To minimize bias in our findings, we used GRADEpro to grade the available evidence. Results: Five studies were enrolled-two randomized controlled trials (RCTs) and three nonrandomized controlled trials (N-RCTs)-that included 291 patients. All patients had coronary disease. ROB assessments showed a relatively high selection and detection bias. Meta-analyses showed that compared to other types of low- or moderate-intensity exercise, Tai Chi could significantly improve VO2max [MD = 4.71, 95% CI (3.58, 5.84), P < 0.00001], but it seemed less effective at improving VO2max as compared to high-intensity exercise. This difference, however, was not statistically significant [MD = -1.10, 95% CI (-2.46, 0.26), P = 0.11]. The GRADEpro showed a low level of the available evidence. Conclusion: Compared to no exercise or other types of exercise with low-to-moderate intensity, Tai Chi seems a good choice for coronary disease rehabilitation in improving cardiorespiratory fitness. However, owing to the poor methodology quality, more clinical trials with large sample size, strict randomization, and clear description about detection and reporting processes are needed to further verify the evidence.
