Background: Hypertension and type 2 diabetes are chronic diseases, which generally require lifetime care. Meditation and yoga can be complementary to pharmacological therapies according to the scientific evidences so far. Brain education-based meditation (BEM) is a technique, which has been known to change brain structure, psychology, and physiology of healthy adult participants. This randomized, nonblinded pilot trial aimed to examine whether BEM affects the conditions of patients with hypertension and/or type 2 diabetes compared with health education classes.
Methods: We randomly allocated 48 patients with hypertension and/or type 2 diabetes to BEM (n=24) or health education (n=24) classes in the Ulsan Junggu Public Health Center in Korea, where the classes were run during the same period and explored the impact of 8-week practice on the serum glutamic-oxaloacetic transaminase, serum glutamic pyruvic transaminase, gamma glutamyl transpeptidase, creatinine, high-density lipoprotein cholesterol, and low-density lipoprotein (LDL) cholesterol. Total RNA was extracted to examine inflammatory gene expressions from the whole blood using PAXgene blood RNA System. In addition, self-reports on mental/physical health were evaluated. The Student’s t test, chi-squared test, and analysis of covariance were used for statistical analysis.
Results: The number of people who participated until the completion of the study was 14 in the control and 21 in the BEM group. After 8 weeks, LDL cholesterol level was significantly decreased in the BEM group after the intervention (13.82mg/dL reduction, P<.05), while it was not significantly altered in the control group. The expression of inflammatory genes was significantly reduced after 8 weeks of the BEM training (0.3-, 0.5-, and 0.2-fold change for NFKB2, RELA, and IL1B, respectively, all P<.05). In the item analysis of mental/physical health self-reports, a significant improvement was confirmed as follows: increases in focus, confidence, relaxation, and happiness; decreases in fatigue, anger, and loneliness (all P<.05). There were no important adverse events or side effects by BEM intervention.
Conclusion: Compared to health education, BEM helps lower LDL cholesterol level and the inflammatory gene expression in the patients with hypertension and/or type 2 diabetes. Moreover, BEM induces positive effects on the self-reported mental/physical states, warranting further study.

- 초록The majority of meditation involves focusing attention on internal events or sensations and becoming aware of emotions. The insula cortex, through a functional connection with the prefrontal cortex and other brain regions, plays a key role in integrating external sensory information with internal bodily state signals and emotional awareness. The purpose of this exploratory study was to examine the resting-state functional connectivity of the insula with other brain regions in meditation practitioners and control subjects. Thirty-five BrainWave Vibration meditation practitioners and 33 controls without meditation experience were included in this study. All subjects underwent 4.68-min resting-state functional scanning runs using magnetic resonance imaging. The anterior and posterior insulae were chosen as seed regions for the functional connectivity map. Meditation practitioners showed significantly greater insula-related functional connectivity in the thalamus, caudate, middle frontal gyrus, and superior temporal gyrus than did controls. Control subjects demonstrated greater functional connectivity with the posterior insula in the parahippocampal gyrus. Our findings suggest that the practice of Brain Wave Vibration meditation may be associated with functional differences in regions related to focused attention, executive control, and emotional awareness and regulation.

- 초록Objective: Meditation can elicit trait-like changes in psychological and social styles, as well as enhancement of emotional regulatory capacity. We investigated the relation between personality traits and emotional intelligence in meditation practitioners. Methods: Seventy-two long-term practitioners of mind-body training (MBT) and 62 healthy comparative individuals participated in the study. The participants completed emotional intelligence questionnaires and the Myers-Briggs Type Indicator (MBTI). Results: The MBT group revealed higher scores on all five emotional intelligence factors than did those in the control group, such as emotional awareness and expression, empathy, emotional thinking, emotional application, and emotional regulation (all p≤0.001). MBT practitioners also had higher scores on the intuition of perceiving function (t =-2.635, p =0.010) and on the feeling of the judging function (t =-3.340, p =0.001) of the MBTI compared with those in the control group. Only the MBT group showed a robust relationship with every factor of emotional intelligence and MBTI-defined intuitive styles, indicating that higher scores of emotional intelligence were related to higher scores for intuition. Conclusion: Emotional intelligence of meditation practitioners showed notable relationships with some features of personality trait. In-depth associations between emotional intelligence and personality traits would help to foster psychological functions in meditation practitioners.

A convergent line of neuroscientific evidence suggests that meditation alters the functional and structural plasticity of distributed neural processes underlying attention and emotion. The purpose of this study was to examine the brain structural differences between a well-matched sample of longterm meditators and controls. We employed whole-brain cortical thickness analysis, based on magnetic resonance imaging, and diffusion tensor imaging to quantify white matter integrity in the brains of 46 experienced meditators compared with 46 matched meditation-naïve volunteers. Meditators, compared with controls, showed significantly greater cortical thickness in the anterior regions of the brain, located in frontal and temporal areas, including the medial prefrontal cortex, superior frontal cortex, temporal pole, and the middle and interior temporal cortices. Significantly thinner cortical thickness was found in the posterior regions of the brain, located in the parietal and occipital areas, including the postcentral cortex, inferior parietal cortex, middle occipital cortex, and posterior cingulate cortex. Moreover, in the region adjacent to the medial prefrontal cortex, both higher fractional anisotropy values and greater cortical thickness were observed. Our findings suggest that long-term meditators have structural differences in both gray and white matter.

- 초록This randomised trial compared the effects of BrainWave Vibration (BWV) training, which involves rhythmic yoga-like meditative exercises, with Iyengar yoga and Mindfulness. Iyengar provided a contrast for the physical components and mindfulness for the "mental" components of BWV. 35 healthy adults completed 10 75-minute classes of BWV, Iyengar, or Mindfulness over five weeks. Participants were assessed at pre- and post intervention for mood, sleep, mindfulness, absorption, health, memory, and salivary cortisol. Better overall mood and vitality followed both BWV and Iyengar training, while the BWV group alone had improved depression and sleep latency. Mindfulness produced a comparatively greater increase in absorption. All interventions improved stress and mindfulness, while no changes occurred in health, memory, or salivary cortisol. In conclusion, increased well-being followed training in all three practices, increased absorption was specific to Mindfulness, while BWV was unique in its benefits to depression and sleep latency, warranting further research.

- 초록Meditation may show differential effects on stress and plasma catecholamines based on genetic polymorphisms in brainderived neurotrophic factor (BDNF) and catechol O-methyl transferase (COMT). Eighty adults (40 men, 40 women; mean age 26 years) who practiced meditation regularly and 57 healthy control adults (35 men, 22 women; mean age 26 years) participated. Plasma catecholamines (norepinephrine (NE), epinephrine (E), and dopamine (DA)) concentrations were measured, and a modified form of the Stress Response Inventory was administered. The results were analyzed using two-way analysis of covariance (ANCOVA) with control and meditation subjects, gene polymorphism as factors, and meditation duration as the covariate. Two-way ANCOVA showed a significant interaction between control and meditation subjects, and BDNF Val66Met polymorphism on DA/NE + DA/E (p=0.042) and NE/E + NE/DA (p=0.046) ratios. A significant interaction was found for control and meditation subjects with COMT Val158Met polymorphism and plasma NE concentrations (p=0.009). Post hoc ANCOVA in the meditation group, adjusted for meditation duration, showed significantly higher plasma NE concentrations for COMT Met carriers than COMT Val/Val subjects (p=0.025). Significant differences of stress levels were found between the control and meditation subjects in BDNF Val/Met (p<0.001) and BDNF Met/Met (p=0.003), whereas stress levels in the BDNF Val/Val genotype did not differ between the control and meditation groups. This is the first evidence that meditation produces different effects on plasma catecholamines according to BDNF or COMT polymorphisms.

- 초록This study was designed to assess the association between stress, positive affect and catecholamine levels in meditation and control groups. The meditation group consisted of 67 subjects who regularly engaged in mind-body training of "Brain-Wave Vibration" and the control group consisted of 57 healthy subjects. Plasma catecholamine (norepinephrine (NE), epinephrine (E), and dopamine (DA)) levels were measured, and a modified form of the Stress Response Inventory (SRI-MF) and the Positive Affect and Negative Affect Scale (PANAS) were administered. The meditation group showed higher scores on positive affect (p = .019) and lower scores on stress (p < .001) compared with the control group. Plasma DA levels were also higher in the meditation (p = .031) than in the control group. The control group demonstrated a negative correlation between stress and positive affects (r =-.408, p = .002), whereas this correlation was not observed in the meditation group. The control group showed positive correlations between somatization and NE/E (r = .267, p = .045) and DA/E (r = .271, p = .042) ratios, whereas these correlations did not emerge in the meditation group. In conclusion, these results suggest that meditation as mind-body training is associated with lower stress, higher positive affect and higher plasma DA levels when comparing the meditation group with the control group. Thus, mind-body training may influence stress, positive affect and the sympathetic nervous system including DA activity.

- 초록Objective The objective of this study was to examine the effectiveness of a meditation-based stress management program in patients with anxiety disorder. Methods Patients with anxiety disorder were randomly assigned to an 8-week clinical trial of either a meditation-based stress management program or an anxiety disorder education program. The Hamilton Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the State–Trait Anxiety Inventory (STAI), the Beck Depression Inventory, and the Symptom Checklist-90—Revised (SCL-90-R) were used to measure outcome at 0, 2, 4, and 8 weeks of the program. Results Compared to the education group, the meditation-based stress management group showed significant improvement in scores on all anxiety scales (HAM-A, P=.00; STAI state, P=.00; STAI trait, P=.00; anxiety subscale of SCL-90-R, P=.00) and in the SCL-90-R hostility subscale (P=.01). Findings on depression measures were inconsistent, with no significant improvement shown by subjects in the meditation-based stress management group compared to those in the education group. The meditation-based stress management group did not show significant improvement in somatization, obsessive–compulsive symptoms, and interpersonal sensitivity scores, or in the SCL-90-R phobic anxiety subscale compared to the education group. Conclusions A meditation-based stress management program can be effective in relieving anxiety symptoms in patients with anxiety disorder. However, well-designed, randomized, and controlled trials are needed to scientifically prove the worth of this intervention prior to treatment.
