IMPORTANCE Migraine is the second leading cause of disability worldwide. Most patients with migraine discontinue medications due to inefficacy or adverse effects. Mindfulness-based stress reduction (MBSR) may provide benefit. OBJECTIVE To determine if MBSR improves migraine outcomes and affective/cognitive processes compared with headache education. DESIGN, SETTING, AND PARTICIPANTSThis randomized clinical trial of MBSR vs headache education included 89 adults who experienced between 4 and 20 migraine days per month. There was blinding of participants (to active vs comparator group assignments) and principal investigators/data analysts (to group assignment).INTERVENTIONS Participants underwent MBSR (standardized training in mindfulness/yoga) or headache education (migraine information) delivered in groups that met for 2 hours each week for 8 weeks. MAIN OUTCOMES AND MEASURESThe primary outcome was change in migraine day frequency (baseline to 12 weeks). Secondary outcomes were changes in disability, quality of life, self-efficacy, pain catastrophizing, depression scores, and experimentally induced pain intensity and unpleasantness (baseline to 12, 24, and 36 weeks). RESULTSMost participants were female (n = 82, 92%), with a mean (SD) age of 43.9 (13.0) years, and had a mean (SD) of 7.3 (2.7) migraine days per month and high disability (Headache Impact Test-6: 63.5 [5.7]), attended class (median attendance, 7 of 8 classes), and followed up through 36 weeks (33 of 45 [73%] of the MBSR group and 32 of 44 [73%] of the headache education group). Participants in both groups had fewer migraine days at 12 weeks (MBSR: −1.6 migraine days per month; 95% CI, −0.7 to −2.5; headache education: −2.0 migraine days per month; 95% CI, −1.1 to −2.9), without group differences (P = .50). Compared with those who participated in headache education, those who participated in MBSR had improvements from baseline at all follow-up time points (reported in terms of point estimates of effect differences between groups) on measures of disability (5.92; 95% CI, 2.8-9.0; P < .001), quality of life (5.1; 95% CI, 1.2-8.9; P = .01), self-efficacy (8.2; 95% CI, 0.3-16.1; P = .04), pain catastrophizing (5.8; 95% CI, 2.9-8.8; P < .001), depression scores (1.6; 95% CI, 0.4-2.7; P = .008), and decreased experimentally induced pain intensity and unpleasantness (MBSR group: 36.3% [95% CI, 12.3% to 60.3%] decrease in intensity and 30.4% [95% CI, 9.9% to 49.4%] decrease in unpleasantness; headache education group: 13.5% [95% CI, −9.9% to 36.8%] increase in intensity and an 11.2% [95% CI, −8.9% to 31.2%] increase in unpleasantness; P = .004 for intensity and .005 for unpleasantness, at 36 weeks). One reported adverse event was deemed unrelated to study protocol.CONCLUSIONS AND RELEVANCE Mindfulness-based stress reduction did not improve migraine frequency more than headache education, as both groups had similar decreases; however, MBSR improved disability, quality of life, self-efficacy, pain catastrophizing, and depression out to 36 weeks, with decreased ...

Objective: To better characterize the ways that migraine affects multiple domains of life.Background: Further understanding of migraine burden is needed. Methods: Adults with migraine randomized to mindfulness-based stress reduction or headache education arms (n = 81) in two separate randomized clinical trials participated in semistructured in-person qualitative interviews conducted after the interventions. Interviews queried participants on migraine impact on life and were audio-recorded, transcribed, and summarized into a framework matrix. A master codebook was created until meaning saturation was reached and magnitude coding established code frequency. Themes and subthemes were identified using a constructivist grounded theory approach. Results: Despite most participants being treated with acute and/or prophylactic medications, 90% (73/81) reported migraine had a negative impact on overall life, with 68% (55/81) endorsing specific domains of life impacted and 52% (42/81) describing impact on emotional health. Six main themes of migraine impact emerged: (1) global negative impact on overall life; (2) impact on emotional health; (3) impact on cognitive function; (4) impact on specific domains of life (work/career, family, social); (5) fear and avoidance (pain catastrophizing and anticipatory anxiety); and (6) internalized and externalized stigma. Participants reported how migraine (a) controls life, (b) makes life How to cite this article:

Background The COVID-19 pandemic has dramatically affected mental health, creating an urgent need for convenient and safe interventions to improve well-being. Online mindfulness interventions show promise for improving depression, anxiety, and general well-being. Objective To assess: 1) the impact of online mindfulness on psychological distress, 2) altruistic efforts, and 3) the quantity, quality, and availability of online mindfulness resources during the COVID-19 pandemic. Methods 233 participants (203 U.S.; 20 international; 10 unknown) participated in this prospective, single-arm, non-randomized clinical trial of a single online mindfulness meditation session with pre- and post-surveys. Main Outcome Measures (a) Mindfulness session helpfulness, online platform effectiveness, and immediate pre- to post-session changes in momentary stress, anxiety, and COVID-19 concern; (b) qualitative themes representing how people are helping others during the pandemic; (c) absolute changes in quantity of mindfulness-oriented web content and free online mindfulness resource availability from May to August 2020. Results Most participants felt the online mindfulness session was helpful and the electronic platform effective for practicing mindfulness (89%, 95% CI: [82 to 93%]), with decreased momentary anxiety (76%; 95% CI: [69 to 83%]), stress (80%; [72 to 86%]), and COVID-19 concern (55%; [46 to 63%]), (p < 0.001 for each measure). Participants reported helping others in a variety of ways during the pandemic, including following public health guidelines, conducting acts of service and connection, and helping oneself in hopes of helping others. “Mindfulness + COVID” search results increased by 52% from May to August 2020. Most (73%) Academic Consortium for Integrative Medicine and Health member websites offer free online mindfulness resources. Conclusions Virtual mindfulness is an increasingly accessible intervention available world-wide that may reduce psychological distress during this isolating public health crisis. Kindness and altruism are being demonstrated during the pandemic. The consolidated online mindfulness resources provided may help guide clinicians and patients.

In 1973, the Velsicol Chemical Company, which manufactured FireMaster, a brominated flame retardant, and NutriMaster, a nutritional supplement, mistakenly shipped hundreds of pounds of FireMaster to grain mills around Michigan where it was incorporated into animal feed and then into the food chain across the state. An estimated 6.5 million Michigan residents consumed polybrominated biphenyl (PBB)-laced animal products leading to one of the largest agricultural accidents in U.S. history. To date, there have been no studies investigating the effects of PBB on epigenetic regulation in sperm, which could explain some of the endocrine-related health effects observed among children of PBB-exposed parents. Fusing epidemiological approaches with a novel in vitro model of human spermatogenesis, we demonstrate that exposure to PBB153, the primary component of FireMaster, alters the epigenome in human spermatogenic cells. Using our novel stem cell-based spermatogenesis model, we show that PBB153 exposure decreases DNA methylation at regulatory elements controlling imprinted genes. Furthermore, PBB153 affects DNA methylation by reducing de novo DNA methyltransferase activity at increasing PBB153 concentrations as well as reducing maintenance DNA methyltransferase activity at the lowest tested PBB153 concentration. Additionally, PBB153 exposure alters the expression of genes critical to proper human development. Taken together, these results suggest that PBB153 exposure alters the epigenome by disrupting methyltransferase activity leading to defects in imprint establishment causing altered gene expression, which could contribute to health concerns in the children of men exposed to PBB153. While this chemical is toxic to those directly exposed, the results from this study indicate that the epigenetic repercussions may be detrimental to future generations. Above all, this model may be expanded to model a multitude of environmental exposures to elucidate the effect of various chemicals on germline epigenetics and how paternal exposure may impact the health of future generations. In recent years, a major focus of research has been the Developmental Origins of Health and Disease (DOHaD) 1. A component of DOHaD research examines the impact of pre-and post-conception risk factors on long-term health and disease progression in adulthood. In terms of pre-conception risk factors, many researchers report that toxicants and environmental exposures can potentially alter the epigenome in gametes, giving these exposures the potential to ultimately impact the health of the next generation 2-5. In 1973, farms across Michigan mistakenly received cattle feed mixed with FireMaster BP-6, a chemical flame retardant composed of a mixture of polybrominated biphenyl compounds (PBBs), rather than NutriMaster, a food additive that increased milk production in farm animals 6-9. PBB-laced animal products were consumed by millions of residents, and the decline in animal
