Mindfulness meditation has emerged as a novel approach to emotion regulation and stress reduction that has several health benefits. Preliminary work has been conducted on mindfulnessbased therapy for insomnia (MBT-I), a meditation-based program for individuals suffering from chronic sleep disturbance. This treatment integrates behavioral treatments for insomnia with the principles and practices of mindfulness meditation. A case illustration of a chronic insomnia sufferer demonstrates the application of mindfulness principles for developing adaptive ways of working with the nocturnal symptoms and waking consequences of chronic insomnia.

Objective: Mindfulness-based interventions (MBI) have been shown to reduce subjective symptoms of insomnia but the effects on objective measures remain unclear. The purpose of this study was to examine sleep EEG microarchitecture patterns from a randomized controlled trial of Mindfulness-Based Stress Reduction (MBSR) and Mindfulness-Based Therapy for Insomnia (MBTI). Methods: Sleep EEG spectral analysis was conducted on 22 participants with chronic insomnia (>6 months) randomized to 8-week MBSR, MBTI, or self-monitoring control (SM). Overnight polysomnography with 6-channel EEG was conducted at baseline, posttreatment, and 6-month follow-up. Spectral power averaged from channels C3/C4 across NREM epochs (excluding N1) was examined for within-group changes and relationships with self-report measures. Results: Increases in absolute NREM beta (16-25Hz) power were observed from baseline to post-treatment (p = .02, d = 0.53) and maintained at 6-month follow-up (p = .01, d = 0.57) in the combined MBI groups, and additionally in the gamma (25-40Hz) range at follow-up for the MBTI group only. No significant changes in these frequency bands were observed for SM. Following mindfulness intervention, NREM beta was positively associated with Five-Facet Mindfulness (FFM) score (rho = 0.37, p = .091) and Insomnia Severity Index (rho =-0.43, p = .047). Conclusion: These results in people with insomnia corroborate prior reports of increased high-frequency sleep EEG power associated with mindfulness training. This change in beta EEG pattern merits further evaluation as a potential marker of the effects of mindfulness meditation on sleep, especially given the contradictory findings in the context of insomnia.

Background: A substantial number of patients with major depressive disorder (MDD) do not sufficiently remit after the first lines of antidepressant treatments, making them vulnerable to poor clinical outcomes. Patients who have not had adequate resolution of their depressive symptoms after four antidepressant treatments and/or have been experiencing their current episode of MDD for two years or more (with insufficient responses to adequate antidepressant treatments) should be evaluated for antidepressant vagus nerve stimulation (VNS Therapy). Adjunctive VNS Therapy is a promising long-term treatment option for patients with difficult-to-treat depression (DTD), offering significantly improved remission rates in comparison with usual treatments. However, VNS Therapy requires specialized treatment centers to support patients. Materials and Methods:In this narrative review, we aim to outline the necessary steps for setting up an antidepressant VNS Therapy service in an efficient manner.Results: Establishing a VNS Therapy service requires several high-level considerations: initiation of a collaborative multidisciplinary team of health care professionals; developing a surgical pathway for implantation; consideration of reimbursement and health care coverage; setting up a specialist clinic to identify optimal candidates for VNS Therapy; educating patients and their families about VNS Therapy; and training health care providers on patient-specific VNS Therapy treatment and long-term treatment management.Conclusions: Antidepressant VNS Therapy is a promising treatment option for the long-term treatment of patients with DTD. We have successfully initiated four VNS Therapy service centers for DTD in the United States, Austria, and Germany. Based on our experiences and lessons learned, herein, we have provided advice to psychiatric centers planning to set up a VNS Therapy service for their patients with DTD.

Graduate medical education (GME) training commonly requires residents and fellows to engage in night float shift work. This review aims to assess the effectiveness of interventions for trainees when preparing for, completing, and recovering from working night float shifts. We reviewed all available studies published prior to September 2019 using PubMed, Scopus, CINAHL, the Cochrane library, PsycINFO, and Google Scholar databases. We included all original, primary research articles assessing either non‐pharmacological or pharmacological interventions on the chronobiological and physiological effects of night float shift work among GME trainees. Five studies (n = 179 patients) met inclusion criteria. Interventions included melatonin in the morning before sleep after night float shifts, napping during night float shifts, modafinil after a night of sleep deprivation, and caffeinated energy drinks after 6 consecutive night float shifts. Melatonin improved one measure of attention. A 2‐hr nap was associated with improved speed related to task switching. Modafinil improved performance in tests of cognition. Caffeinated energy drinks led to improvement in select driving performance variables and reaction time. Effect sizes for outcome variables were calculated. Heterogeneity among the studies precluded combining the data in a meta‐analysis. According to GRADE criteria, the quality of the evidence in these studies was low or very low. Our findings suggest GME trainees may benefit from utilising a limited number of interventions when preparing for or recovering from night float shift work. More investigation is needed to identify interventions that could help GME trainees adapt to and recover from working night float shifts.
