Experiences of Irritable Bowel Syndrome Patients in a Virtual Yoga Program: Qualitative Findings from a Clinical Trial.

BACKGROUND AND AIMS: In-person yoga interventions have shown feasibility and effectiveness in improving the outcomes of patients with irritable bowel syndrome (IBS), but experiences in virtual yoga interventions have not been examined. This study aimed to explore patients' experiences of a virtually delivered yoga intervention for IBS. METHODS: An embedded qualitative substudy was included in a randomized controlled trial examining the feasibility and effectiveness of a virtual yoga program among adult patients with IBS. Semi-structured interviews captured participants' past and current experiences, program satisfaction, perceived impact on IBS symptoms and overall physical and mental health, facilitators and barriers to participation, perceptions of social support and supervised learning, and input on improving future programming. Data were coded and analyzed in duplicate using NVivo 12. An analytic template based on the interview guide was developed and thematic analysis identified themes, as well as the relationship between themes and subthemes. RESULTS: Among the 14 participants (all female, mean age 47.7 years), three major themes were identified: (1) positive experience in the yoga program, (2) incorporating yoga into IBS management post-study, and (3) recommendations for program improvement. CONCLUSION: Patients with IBS experience in a virtual yoga program was positive with improvements in physical and mental health outcomes. Considering the barriers and facilitators to participating in an online yoga program along with participant recommendations may improve future intervention design and delivery to increase self-efficacy and confidence among patients with IBS.

Infants with Congenital Adrenal Hyperplasia Exhibit Thalamic Discrepancies in Early Brain Structure.

INTRODUCTION: Patients with classical congenital adrenal hyperplasia (CAH) have prenatal and postnatal hormonal imbalances. To characterize the ontogeny of reported brain and behavior changes in older children with CAH, we aimed to study the brain structure in infants with CAH compared to healthy controls. METHODS: We performed neuroimaging in 16 infants with classical CAH due to 21-hydroxylase deficiency (8 males, gestational age 38.2 ± 1.7 weeks, post-conceptional age [PCA] 42.2 ± 3.0 weeks) and 14 control infants (9 males, gestational age 38.5 ± 1.8 weeks, PCA 42.5 ± 2.4 weeks) utilizing 3-Tesla magnetic resonance imaging. Regional brain volumes were adjusted for PCA and sex, along with an additional adjustment for total brain volume (TBV), for group comparisons by regression analyses (mean, 95% confidence interval [CI]). The degree to which each brain region was differentiated between CAH and control infants was examined by relaimpo analyses, adjusting for all other brain regions, PCA, and sex. RESULTS: Infants with CAH had significantly smaller thalamic volumes (8,606 mm3, 95% CI [8,209, 9,002]) compared to age-matched control infants (9,215 mm3, 95% CI [8,783, 9,647]; ß = -609; p = 0.02) which remained smaller after further adjustment for TBV. Upon further adjustment for TBV, the temporal lobe was larger in infants with CAH (66,817 mm3, CI [65,957, 67,677]) compared to controls (65,616 mm3, CI [64,680, 66,551]; ß = 1,202, p = 0.03). The brain regions most differentiated between CAH versus controls were the thalamus (22%) and parietal lobe (10%). CONCLUSIONS: Infants with CAH exhibit smaller thalamic regions from early life, suggesting a prenatal influence on brain development in CAH. Thalamic emergence at 8-14 weeks makes the region particularly vulnerable to changes in the intrauterine environment, with potential implications for later maturing brain regions. These changes may take time to manifest, meriting longitudinal study through adolescence in CAH.

Meditation and Yoga for Irritable Bowel Syndrome: A Randomized Clinical Trial.

INTRODUCTION: Delivered in person, yoga is effective in managing irritable bowel syndrome (IBS) symptoms. The evidence for efficacy, feasibility, and safety of virtually delivered yoga for patients with IBS is unknown. METHODS: Adults diagnosed with IBS were randomized to either Hatha yoga intervention of 8 weekly online classes delivered virtually or an advice-only control group and assessed at baseline and postintervention. We used an unadjusted ANOVA to determine differences between and within groups on the primary outcome (decrease of ≥50 points in IBS Symptom Severity Scale [IBS-SSS]) and secondary outcomes (quality of life, anxiety and depression, fatigue, somatic symptoms, perceived stress, COVID-19 stress, and self-compassion). We assessed feasibility through recruitment and attrition rates, adherence, participant satisfaction, and safety (i.e., adverse events). RESULTS: Seventy-nine people participated (mean age 45.4 years [SD = 14.0], 92% women, 20% attrition rate). IBS-SSS decreased significantly in the treatment group (Δ change = 54.7, P = 0.028), but not in the control group (Δ change = 22.6, P = 0.277). Fourteen patients (37%) in the yoga group reached a clinically relevant decrease of ≥50 points on the IBS-SSS postintervention compared with 8 patients (20%) in the control group ( P = 0.242). No significant difference was found between groups in IBS-SSS score postintervention ( P = 0.149), but significant differences in favor of the treatment group for quality of life ( P = 0.030), fatigue ( P = 0.035), and perceived stress ( P = 0.040) were identified. The yoga program demonstrated feasibility. Intention to practice yoga decreased significantly in both groups from baseline to postintervention ( P < 0.001). However, the decline in intention did not correlate with practice minutes. DISCUSSION: Virtually delivered yoga is safe and feasible, and effective in reducing IBS symptoms. Based on the primary end point, the intervention was not superior to an advice-only control group.

Meditation and yoga for irritable bowel syndrome: study protocol for a randomised clinical trial (MY-IBS study).

INTRODUCTION: When delivered in person, yoga has been shown to be effective in managing irritable bowel syndrome (IBS) symptoms. Research is needed to test the feasibility and effectiveness of yoga as a therapeutic option when delivered virtually. The primary aim of the mind and yoga for IBS randomised controlled trial is to determine the effects of an 8-week virtual meditation and yoga intervention on IBS symptom severity compared with an advice-only active control group. METHODS AND ANALYSIS: Adults diagnosed with IBS will be randomised to receive either a Upa Yoga intervention or an advice-only control group. The intervention will consist of weekly online classes for 8 weeks delivered by a facilitator using Microsoft Office Teams and daily home practice. Feasibility will be evaluated by examining recruitment and attrition rates, adherence, participant satisfaction with the programme and safety. The primary outcome is IBS symptom severity, and key secondary outcomes include (but not limited to) quality of life, anxiety and depression symptoms, COVID-19-related stress and anxiety, and fatigue. Outcomes will be assessed at baseline, 4 weeks and 8 weeks. An embedded design experimental model substudy will be conducted post intervention using qualitative research methods to identify participants' experiences in the yoga programme. ETHICS AND DISSEMINATION: This study has been approved by the Conjoint Health Research Ethics Board (REB ID 20-0084). Findings will be disseminated through peer-reviewed publication, conference presentation and social media. TRIAL REGISTRATION NUMBER: NCT04302623.

Evaluation of an integrated yoga program in patients with inflammatory bowel disease: A pilot study.

BACKGROUND: The effects of integrated yoga programs on mental health outcomes in inflammatory bowel disease (IBD) have not been well explored. To explore the acceptability, implementation and effectiveness of an integrated eight-week yoga program plus aromatherapy massage in patients with IBD. METHODS: Nine participants with documented IBD were recruited from a gastroenterology clinic in Calgary, Alberta, Canada to participate in an integrated yoga program weekly for eight weeks with outcomes assessed at baseline and week 8. Primary outcomes were assessed using Theory of Planned Behaviour as a guiding theory to identify salient beliefs from qualitative analysis of a semi-structured interview, survey items measuring the strength of beliefs and a daily log was used to capture adherence and adverse events. Secondary outcomes were collected using validated survey tools examining anxiety, depression, stress, sleep quality, and physical and mental quality of life. RESULTS: Attitude, subjective norm and perceived behavioral control beliefs pertinent to the yoga intervention and daily practice were identified. Participants reported feeling the intervention was very helpful; however, felt guilt about not completing daily practices which decreased confidence and intention to continue with the practice. An average of 55.6% of in-person sessions were attended and decreased over time. Participants practiced on average of 5.4 days per week. Depression and mental health scores improved at week 8 from baseline. CONCLUSIONS: We were able to identify key salient beliefs of IBD patients in regard to an integrated yoga plus aromatherapy massage intervention. This intervention appears to be acceptable and further research should explore its potential to improve mental and physical health outcomes including IBD symptoms.

Brain biomarkers and neuropsychological outcomes of pediatric posterior fossa brain tumor survivors treated with surgical resection with or without adjuvant chemotherapy.

PURPOSE: Children with brain tumors experience cognitive late effects, often related to cranial radiation. We sought to determine differential effects of surgery and chemotherapy on brain structure and neuropsychological outcomes in children who did not receive cranial radiation therapy (CRT). METHODS: Twenty-eight children with a history of posterior fossa tumor (17 treated with surgery, 11 treated with surgery and chemotherapy) underwent neuroimaging and neuropsychological assessment a mean of 4.5 years (surgery group) to 9 years (surgery + chemotherapy group) posttreatment, along with 18 healthy sibling controls. Psychometric measures assessed IQ, language, executive functions, processing speed, memory, and social-emotional functioning. Group differences and correlations between diffusion tensor imaging findings and psychometric scores were examined. RESULTS: The z-score mapping demonstrated fractional anisotropy (FA) values were ≥2 standard deviations lower in white matter tracts, prefrontal cortex gray matter, hippocampus, thalamus, basal ganglia, and pons between patient groups, indicating microstructural damage associated with chemotherapy. Patients scored lower than controls on visuoconstructional reasoning and memory (P ≤ .02). Lower FA in the uncinate fasciculus (R = -0.82 to -0.91) and higher FA in the thalamus (R = 0.73-0.91) associated with higher IQ scores, and higher FA in the thalamus associated with higher scores on spatial working memory (R = 0.82). CONCLUSIONS: Posterior fossa brain tumor treatment with surgery and chemotherapy affects brain microstructure and neuropsychological functioning years into survivorship, with spatial processes the most vulnerable. Biomarkers indicating cellular changes in the thalamus, hippocampus, pons, prefrontal cortex, and white matter tracts associate with lower psychometric scores.
