Effects of mindfulness meditation and Acceptance and commitment therapy in patients with obstructive sleep apnea with residual excessive sleepiness: A randomized controlled pilot study.

OBJECTIVE: Assessing the effects of Mindfulness-Based Stress Reduction (MBSR) on symptoms of OSA, especially on the primary outcome, excessive daytime sleepiness (EDS). METHODS: Parallel randomized controlled trial. 16 OSA patients with residual EDS (rEDS) were randomized and assigned to either a standardized 8-week MBSR program or a time-matched program on Acceptance and Commitment Therapy (ACT). Both programs were conducted online. Participants answered questionnaires online at baseline (pre), post-intervention (post), three months after the intervention (follow-up) and were blinded to whether their group was the treatment or active control group but not to group allocation (partial blinding). Three participants dropped out early. Most analyses are based on the remaining 13 patients. RESULTS: There was a significant difference between the MBSR (n = 7) and ACT group (n = 6) in changes of EDS between pre and post (Cohen's d = 1.24, CI [0.01, 2.42]) and a significant reduction of EDS for patients in the ACT group at post (Cohen's d = 1.18 and [0.08, 2.22]). This EDS reduction averaging 2.17 points on the Epworth Sleepiness Scale reached the prespecified bar for clinical significance of two points on that scale. Insomnia symptoms, a secondary outcome, reduced significantly following ACT (Cohen's d = 1.43 [0.23, 2.58]). In MBSR, both participants and the MBSR-trainer judged movement-based exercises to be most efficacious. CONCLUSION: ACT shows potential as adjunctive therapy for OSA with rEDS, although further studies are needed. It seems promising to develop therapeutic approaches for OSA with rEDS using ACT, especially if they are tailored to the needs specific to this patient group.

Blind spots on western blots: Assessment of common problems in western blot figures and methods reporting with recommendations to improve them.

Western blotting is a standard laboratory method used to detect proteins and assess their expression levels. Unfortunately, poor western blot image display practices and a lack of detailed methods reporting can limit a reader's ability to evaluate or reproduce western blot results. While several groups have studied the prevalence of image manipulation or provided recommendations for improving western blotting, data on the prevalence of common publication practices are scarce. We systematically examined 551 articles published in the top 25% of journals in neurosciences (n = 151) and cell biology (n = 400) that contained western blot images, focusing on practices that may omit important information. Our data show that most published western blots are cropped and blot source data are not made available to readers in the supplement. Publishing blots with visible molecular weight markers is rare, and many blots additionally lack molecular weight labels. Western blot methods sections often lack information on the amount of protein loaded on the gel, blocking steps, and antibody labeling protocol. Important antibody identifiers like company or supplier, catalog number, or RRID were omitted frequently for primary antibodies and regularly for secondary antibodies. We present detailed descriptions and visual examples to help scientists, peer reviewers, and editors to publish more informative western blot figures and methods. Additional resources include a toolbox to help scientists produce more reproducible western blot data, teaching slides in English and Spanish, and an antibody reporting template.
