Beneficial effect of GABA-rich fermented milk on insomnia involving regulation of gut microbiota

In this study, milk was fermented with Lactobacillus brevis DL1-11, a strain with high GABA-producing capacity. The potential beneficial effects of this fermented milk on anxiety and sleep quality were evaluated in animal experiments. Sixty mice were divided into control, non-GABA fermented milk (NGFM), low-dose GABA fermented milk (LGFM, 8.83 mg/kg.bw), medium-dose GABA fermented milk (MGFM, 16.67 mg/kg.bw), high-dose GABA fermented milk (HGFM, 33.33 mg/kg.bw) and diazepam groups. The results of open field test and elevated plus-maze test indicated decreases in anxiety behavior after oral HGFM administration. Moreover, mice in the HGFM group exhibited a significantly prolonged sleep time after an intraperitoneal injection of sodium pentobarbital and a shortened sleep latency after an intraperitoneal injection of sodium barbital. These results indicate a beneficial effect of HGFM on sleep. Additionally, significant increases in the relative abundances of Ruminococcus, Adlercreutzia and Allobaculum and the levels of some short-chain fatty acids (SCFAs), such as butyric acid, were observed in the HGFM group. The results suggest that GABA-fermented milk may improve sleep and the protective pathways may involve in regulation of gut microbiota and increase of SCFAs level.Graphical abstract

DiscussionIt is expected that proACT-S is an efficacious brief sleep-focused self-help treatment for people with major depression and insomnia. If proven efficacious, due to its self-help nature, proACT-S may be applicable as a community-based early intervention, thereby  reducing the burden of the public healthcare system in Hong Kong.Trial registrationClinicalTrials.govNCT04228146.

Abstract Cognitive behavioural therapy for insomnia is the recommended treatment for chronic insomnia. However, up to a quarter of patients dropout from cognitive behavioural therapy for insomnia programmes. Acceptance, mindfulness and values-based actions may constitute complementary therapeutic tools to cognitive behavioural therapy for insomnia. The current study sought to evaluate the efficacy of a remotely delivered programme combining the main components of cognitive behavioural therapy for insomnia (sleep restriction and stimulus control) with the third-wave cognitive behavioural therapy acceptance and comm...

CONCLUSION: These results identify clinical features of veterans and service members with mTBI(s) who are at highest risk for pain-related disability. These findings also demonstrate the need to consider mental health and sleep problems in their pain evaluation and treatment approach. PMID: 33007066 [PubMed - as supplied by publisher]

CONCLUSIONS: Chronic insomnia is prevalent among OSA patients. Our study highlights the need for detailed evaluation of patients with sleep breathing disorders to diagnose other important sleep and mood disorders (such as depression and anxiety), given their frequent association.

This study showed an association between reduced REM and increased mortality, but it did not demonstrate the cause of the association. REM deprivation could independently contribute to the development of numerous other diseases. The results apply more clearly to older adults, given that the age groups studied averaged in the 50s and 70s. Short REM may also be a marker of a sick or aging brain; less REM sleep has already been tied to a greater risk of dementia. Overall, ensuring adequate REM sleep is important to protecting your long-term health. Getting better sleep in middle age and beyond Maintaining good sleep should re...

This controlled clinical trial observed significant added benefit to reduce symptoms of insomnia with use of a closed ‐loop, acoustic stimulation neurotechnology that echoes tones linked to brainwaves (HIRREM), compared to a sham using randomly generated tones. There was also significant improvement in multiple measures of autonomic cardiovascular regulation, with durability to 4 months postintervention, and gro up differences for sleep efficiency, total sleep time, and sleep onset latency. Results suggest that this noninvasive, nondrug intervention could provide a viable alternative for moderate to severe insomnia....

We describe our efforts leading to the identification of a promising set of dual orexin receptor antagonists (DORAs) which subsequently went through physiology-based pharmacokinetic and pharmacodynamic modelling 1 and finally led to the selection of daridorexant ( 93 ) currently in phase 3 clinical trials for the treatment of insomnia disorders.
