ABSTRACT

INTRODUCTION: Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD) can profoundly affect quality of life and are influenced by stress and resiliency. The impact of mind-body interventions (MBIs) on IBS and IBD patients has not previously been examined. METHODS: Nineteen IBS and 29 IBD patients were enrolled in a 9-week relaxation response based mind-body group intervention (RR-MBI), focusing on elicitation of the RR and cognitive skill building. Symptom questionnaires and inflammatory markers were assessed pre- and post-intervention, and at short-term follow-up. Peripheral blood transcriptome analysis was performed to identify genomic correlates of the RR-MBI. RESULTS: Pain Catastrophizing Scale scores improved significantly post-intervention for IBD and at short-term follow-up for IBS and IBD. Trait Anxiety scores, IBS Quality of Life, IBS Symptom Severity Index, and IBD Questionnaire scores improved significantly post-intervention and at short-term follow-up for IBS and IBD, respectively. RR-MBI altered expression of more genes in IBD (1059 genes) than in IBS (119 genes). In IBD, reduced expression of RR-MBI response genes was most significantly linked to inflammatory response, cell growth, proliferation, and oxidative stress-related pathways. In IBS, cell cycle regulation and DNA damage related gene sets were significantly upregulated after RR-MBI. Interactive network analysis of RR-affected pathways identified TNF, AKT and NF-κB as top focus molecules in IBS, while in IBD kinases (e.g. MAPK, P38 MAPK), inflammation (e.g. VEGF-C, NF-κB) and cell cycle and proliferation (e.g. UBC, APP) related genes emerged as top focus molecules. CONCLUSIONS: In this uncontrolled pilot study, participation in an RR-MBI was associated with improvements in disease-specific measures, trait anxiety, and pain catastrophizing in IBS and IBD patients. Moreover, observed gene expression changes suggest that NF-κB is a target focus molecule in both IBS and IBD-and that its regulation may contribute to counteracting the harmful effects of stress in both diseases. Larger, controlled studies are needed to confirm this preliminary finding. TRIAL REGISTRATION: ClinicalTrials.Gov NCT02136745.

ABSTRACT

BACKGROUND: This study examined the feasibility, safety and efficacy of an 8-week Relaxation Response (RR)-based group. METHODS: Twenty-two depressed Chinese American immigrants were recruited. Outcomes measures were response and remission rates, the Hamilton Rating Scale for Depression, Clinical Global Impressions Scale, Quality of Life Enjoyment and Satisfaction Questionnaire, and the Multidimensional Scale of Perceived Social Support Scale. RESULTS: Participants (N = 22) were 82% female, mean age was 53 (± 12). After intervention, completers (N = 15) showed a 40% response rate and a 27% remission rate, and statistically significant improvement in most outcome measures. DISCUSSION: The RR-based group is feasible and safe in treating Chinese American immigrants with depression.

ABSTRACT

OBJECTIVES: This pilot study evaluated the effectiveness of a comprehensive mind body intervention for weight loss in overweight and obesity and the maintenance of weight loss at 6-month follow-up. DESIGN: Thirty-one overweight and obese employees (Body Mass Index (BMI) 28.6-47.9 kg/m²) from a large corporation participated in a 20-week comprehensive mind body intervention targeting weight loss. MAIN OUTCOME MEASURES: Weight, BMI, waist and hip circumference, rate pressure product (RPP), blood pressure, fasting blood glucose, cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and psychological variables were collected at baseline, post-intervention, and 6-month follow-up. RESULTS: Using linear mixed model analyses, the intervention resulted in significant mean weight loss (-4.3 kg, 95% CI -5.8 to -2.8), decreases in BMI (-1.51, 95% CI -2.1 to -1.0), hip circumference measurement (-4.3 cm, 95% CI -6.9 to -1.5), and triglyceride levels (95% CI -33.1 to -4.8). In 6-month follow-up after intervention, statistically significant improvements in weight, BMI and waist measurement were sustained. Participants also showed positive changes in self-reported psychological indices: food-related disinhibition, and hunger both decreased significantly (p<0.01); general self-efficacy increased (p<0.05); positive affect increased (p<0.001); physical function and self-esteem increased (p<0.01); and measures of health-promoting behaviors on 4 subscales (health responsibility, physical activity, nutrition, and stress management) also showed statistically significant improvements (p<0.001) at post-intervention and 6-month follow-up. CONCLUSIONS: This comprehensive mind body intervention showed modest effects on physical, laboratory, and psychological outcomes, both immediately following treatment and at 6-month follow-up, in overweight and obese individuals.

ABSTRACT

Background. This pilot study examined the feasibility and efficacy of providing Qigong treatment in a health center to Chinese Americans with major depressive disorder (MDD). Methods. Fourteen Chinese Americans with MDD were enrolled, and they received a 12-week Qigong intervention. The key outcome measurement was the 17-item Hamilton Rating Scale for Depression (HAM-D17); the Clinical Global Impressions-Severity (CGI-S) and -Improvement (CGI-I), the Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form (Q-LES-Q-SF), and the Multidimensional Scale of Perceived Social Support (MSPSS) were also administered. Positive response was defined as a decrease of 50% or more on the HAM-D17, and remission was defined as HAM-D17 ≤ 7. Patients' outcome measurements were compared before and after the Qigong intervention. Results. Participants (N = 14) were 64% female, with a mean age of 53 (±14). A 71% of participants completed the intervention. The Qigong intervention resulted in a positive treatment-response rate of 60% and a remission rate of 40% and statistically significant improvement, as measured by the HAM-D17, CGI-S, CGI-I, Q-LES-Q-SF, and the family support subscale of the MSPSS. Conclusions. The Qigong intervention provided at a health care setting for the treatment of primary care patients with MDD is feasible. Further studies with larger sample sizes are warranted.

ABSTRACT

OBJECTIVE: This study examined the feasibility, safety, and efficacy of using tai chi for treating major depressive disorder. DESIGN: Thirty-nine Chinese Americans with major depressive disorder were randomized into a 12-wk tai chi intervention or a waitlisted control group in a 2:1 ratio. The key outcome measurement was the 17-item Hamilton Rating Scale for Depression. Positive response was defined as a decrease of 50% or more on the 17-item Hamilton Rating Scale for Depression, and remission was defined as a score of 7 or lower on the 17-item Hamilton Rating Scale for Depression. RESULTS: Of the participants (n = 39), 77% were women, and mean (SD) age was 55 (10) years. There were 26 (67%) participants in the tai chi intervention group and 13 (33%) in the control group. Of the participants in the tai chi group, 73% completed the intervention; no adverse events were reported. We observed trends toward improvement in the tai chi intervention group, compared with the control group, in positive treatment-response rate (24% vs. 0%) and remission rate (19% vs. 0%), although the differences in our small sample did not reach statistical significance. CONCLUSIONS: A randomized controlled trial of tai chi is feasible and safe in Chinese American patients with major depressive disorder. These promising pilot study results inform the design of a more definitive trial.

ABSTRACT

Attentional deficits are a core symptom of schizophrenia. Post-mortem analyses of the brains of schizophrenics reveal consistent abnormalities in γ-aminobutyric acid (GABA) interneurons indicative of reduced cortical GABA transmission, raising the possibility that this pathology contributes to attentional deficits. We examined whether blockade of prefrontal cortex (PFC) GABA(A) receptors with bicuculline (BMI) impairs attention in rats using the 5-choice serial reaction time task (5CSRTT). For comparison, we also examined whether administration of the GABA(A) receptor agonist muscimol (MUS) would improve attention. In parallel, we examined the effects of both manipulations on activity in an open field and on motivation using the intracranial self-stimulation (ICSS) test. BMI increased PFC neuronal activity, as reflected by increased Fos immunolabeling, and impaired attention, as reflected by decreased accuracy and increased omissions. Although increased omissions also may reflect reductions in locomotor activity or motivation, the overall pattern of effects does not support either of these interpretations: BMI did not affect locomotor activity, and it enhanced motivation in the ICSS test. MUS did not affect attention, although it increased impulsive behavior at a dose that suppressed PFC neuronal activity, as reflected by decreased Fos immunolabeling. These impulsivity effects are not due to altered locomotor activity (which was decreased) or motivation (which was not affected). Our data support the hypothesis that cortical GABA neurons have an important role in regulating attention and may have direct implications for the treatment of schizophrenia.
