Effect of Acupuncture on Pregnancy-Related Insomnia and Melatonin: A Single-Blinded, Randomized, Placebo-Controlled Trial

Gong's acupuncture treatment for mid pregnancy insomnia and anxiety: A case report

RATIONALE

Gong's brain acupuncture (GBA) is a acupuncture technique that restores the balance of the central nervous system by stimulating specific acupoints on the skull to transmit stimulation to the nerves. Insomnia during pregnancy is an increasingly concerning issue, and GBA provides new solutions.

PATIENTS CONCERNS

The patient, a 26-year old woman at 26 + 1 weeks of pregnancy, presented with unexplained insomnia for 3 weeks. Her symptoms included difficulty initiating sleep, light sleep, and intermittent wakefulness throughout the night.

DIAGNOSES

The patient was diagnosed with primary insomnia, scoring 16 on the Pittsburgh sleep quality index, which indicates poor sleep quality. Her self-rating anxiety scale (SAS) score was 49 points, suggesting that she had not yet reached a state of mild anxiety.

INTERVENTIONS

The patient received 15 sessions of GBA treatment.

OUTCOMES

One month after treatment completion, the patient's Pittsburgh sleep quality index score improved to 3 points, indicating good sleep quality. Her self-rating anxiety scale score decreased to 39 points.

LESSONS

This case report demonstrated the successful treatment of mid pregnancy insomnia with GBA, providing preliminary evidence for further research on the therapeutic potential of GBA. However, further research is still needed to enhance persuasiveness.

The Elephant in the Room: A Systematic Review of the Application and Effects of Psychological Treatments for Pregnant Women with Dual Pathology (Mental Health and Substance-Related Disorders)

PURPOSE

Maternal mental health and substance use, referred to as dual pathology, represent significant concerns associated with adverse pregnancy and birth outcomes, a prevalence higher than commonly anticipated. Nonetheless, a notable dearth exists ofevidence-based treatment protocols tailored for pregnant women with dual pathology.

METHODS

A systematic review, adhering to the PRISMA methodology, was conducted.

RESULTS

Out of the 57 identified papers deemed potentially relevant, only 2were ultimately included. Given the limited number of studies assessing the efficacy of psychological interventions utilizing randomized controlled trials (RCTs) for both mental health and substance misuse, and considering the diverse objectives and measures employed, definitive conclusions regarding the effectiveness of psychological interventions in this domain prove challenging.

CONCLUSIONS

Maternal mental health appears to be the proverbial "elephant in the room". The development of specialized and integrated interventions stands as an imperative to effectively address this pressing issue. As elucidated in the present review, these interventions ought to be grounded in empirical evidence. Furthermore, it is essential that such interventions undergo rigorous evaluation through RCTs to ascertain their efficacy levels. Ultimately, the provision of these interventions by psychology/psychiatric professionals, both within clinical practice and the RCTs themselves, is recommended to facilitate the generalizability of the results to specialized settings.

Effectiveness and safety of acupuncture in treatment of pregnancy-related symptoms: a systematic review and Meta-analysis

OBJECTIVE

To systematically evaluate the efficacy and safety of acupuncture (AM) in the treatment of pregnancy-related symptoms such as acute vomiting during pregnancy.

METHODS

We comprehensively searched the available literature up to November 2021, including PubMed, Embase, Cochrane Library, Chinese Biomedical Literature Database, and China National Knowledge Infrastructure Database, for randomized controlled trials (RCTs) on AM for the treatment of severe vomiting, insomnia, pharyngeal and pelvic pain, mood abnormalities, and dyspepsia during pregnancy.

RESULTS

Sixteen RCTs with a cumulative sample size of 1178 cases were included. Of these, 964 patients were included in the Meta-analysis. The Meta-analysis results showed that AM was more efficient than Western medicine in treating discomfort during pregnancy [odds ratio (OR) = 1.19, 95% confidence interval (CI) (1.11, 1.28), P < 0.01]. AM was better than the control group in improving the visual analog scale scores [standard mean difference (SMD) = 0.62, 95% CI(0.53, 0.71), P < 0.01]. AM was superior to the control group in improving Numerical Rating Scale (NRS) symptom scores [OR = 7.31, 95% CI(3.36, 15.94), P < 0.01]. There was no significant difference in adverse effects between the AM and sham-AM groups and the analgesic drug group [OR = 0.70, 95% CI(0.39, 1.28), P = 0.25], but the treatment and control groups had mild adverse effects with a low incidence.

CONCLUSIONS

AM is more effective than other treatments or pharmacotherapy alone in the treatment of pregnancy-related symptoms, and is relatively safe. However, the quality of the included trials was rather poor, and high-quality studies are required to confirm our findings.

Acupuncture in circadian rhythm sleep-wake disorders and its potential neurochemical mechanisms

Circadian rhythm sleep-wake disorders (CRSWDs) are becoming increasingly common in modern societies due to lifestyle changes. The detrimental effects of CRSWDs on sleep and psychological health have attracted considerable attention recently. Alternative remedies for the treatment of CRSWDs have also gained attention in recent years owing to the limitations of medications. Several in vivo and clinical investigations have shown that acupuncture, one of the most important components of traditional Chinese medicine (TCM), has been shown to modulate sleep-related circadian rhythms. Owing to the lack of research on the mechanism and effectiveness of acupuncture in treating CRSWDs, clinical applications of acupuncture have not gained popularity. This paper reviews the acupuncture methods, acupoint selection, and biochemical indicators supplied by in vivo and clinical studies to explore the effectiveness of acupuncture, and summarizes the circadian rhythm mechanisms and the acupuncture characteristics on circadian rhythm. The neurochemical mechanisms linked to acupuncture in treating CRSWDs are also outlined from the perspective of the central and peripheral biological clocks. Lastly, the inadequacy of previous studies on CRSWDs and conflicting results regarding acupuncture are explored and future research directions are envisioned.

A Systematic Review and Meta-Analysis Protocol to Establish How Common Clinical Acupoint Stimulation-Related Therapies Should Be Used for Managing Insomnia

Background

Many studies have now investigated the effects of common clinical acupoint stimulation-related therapies (ASRTs) following the meridian theory of traditional Chinese medicine for the management of insomnia. However, ASRT choice is currently based on personal clinical experience or patient preference. This study will review the common ASRTs reported in clinical trials and analyze their efficacy and safety for managing insomnia with or without co-morbidities.

Methods

English and Chinese databases will be thoroughly searched, and other potentially eligible trials will be obtained by reviewing reference lists of identified studies and previous reviews. Only randomized controlled trials (RCTs) of common clinical ASRTs to manage insomnia published in peer-reviewed journals will be considered. Sleep quality questionnaires or indices will be considered as the main outcome, while the secondary outcomes will include sleep parameters, daytime dysfunction, quality of life, and adverse effects. Two reviewers will independently investigate eligible RCTs, extract information, analyze their methodological quality, and employ Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria to evaluate the strength of the evidence. The treatment impact of various ASRTs will be calculated using meta-analysis techniques, and the degree of study heterogeneity will be assessed using Cochrane's Q and I-squared statistics. Subgroup and sensitivity analyses will be used to evaluate the reliability of the results.

Results

Our systematic review and meta-analysis will present up-to-date evidence on: 1) which common clinical ASRTs are beneficial for the management of insomnia; and 2) whether the effects of common clinical ASRTs on insomnia vary depending on clinical, participant, and treatment characteristics.

Conclusion

The results of our review should help decision-makers make educated choices regarding evidence-based non-pharmacological management options for insomnia.

Electroacupuncture ameliorates cerebrovascular impairment in Alzheimer's disease mice via melatonin signaling

AIMS

Cerebrovascular impairment contributes to the pathogenesis of Alzheimer's disease (AD). However, it still lacks effective intervention in clinical practice. Here, we investigated the efficacy of electroacupuncture (EA) in cerebrovascular repair in 3xTg-AD mice and its mechanism.

METHODS

3xTg-AD mice were employed to evaluate the protective effect of EA at ST36 acupoint (EAST36). Behavioral tests were performed to assess neurological disorders. Laser speckle contrast imaging, immunostaining, and Western blot were applied to determine EAST36-boosted cerebrovascular repair. The mechanism was explored in 3xTg mice and endothelial cell cultures by melatonin signaling modulation.

RESULTS

EAST36 at 20/100 Hz effectively alleviated the olfactory impairment and anxiety behavior and boosted cerebrovascular repair in AD mice. EAST36 attenuated cerebral microvascular degeneration in AD mice by modulating endothelial cell viability and injury. Consequently, the Aβ deposits and neural damage in AD mice were reversed after EAST36. Mechanistically, we revealed that EAST36 restored melatonin levels in AD mice. Melatonin supplement mimicked the EAST36 effect on cerebrovascular protection in AD mice and endothelial cell cultures. Importantly, blockage of melatonin signaling by antagonist blunted EAST36-induced cerebrovascular recovery and subsequent neurological improvement.

CONCLUSIONS

These findings provided strong evidence to support EAST36 as a potential nonpharmacological therapy against cerebrovascular impairment in AD. Further study is necessary to better understand how EAST36 treatment drives melatonin signaling.

Impact of Acupuncture on Sleep and Comorbid Symptoms for Chronic Insomnia: A Randomized Clinical Trial

STUDY OBJECTIVES

To evaluate the efficacy and safety of acupuncture at HT 7 (Shenmen) and KI 7 (Fuliu) on sleep and comorbid symptoms for chronic insomnia.

METHODS AND DESIGN

A randomized, single-blind, parallel and sham-controlled trial consisted of an acupuncture group (n = 41) and a sham acupuncture group (n = 41). Setting: a tertiary hospital of integrated Chinese and Western medicine. Participants: 82 subjects with chronic insomnia based on the International Classification of Sleep Disorders, Third Edition (ICSD-3). Interventions: a 10-session acupuncture treatment at bilateral HT 7 and KI 7 or sham acupoints with shallow needling was performed over 3 weeks. Measurements: the Pittsburgh sleep quality index (PSQI) and insomnia severity index (ISI) were evaluated at baseline, posttreatment, and at two follow-ups as the primary outcome measures. Polysomnography (PSG) on two consecutive nights, the Beck anxiety inventory (BAI), the Beck depression inventory (BDI) fatigue severity scale (FSS) and the Epworth sleepiness scale (ESS) were evaluated at baseline and posttreatment as the secondary outcome measures.

RESULTS

After the treatments, PSQI scores decreased by 5.04 in the acupuncture group and 2.92 in the sham acupuncture group. ISI scores decreased by 7.65 in the acupuncture group and 5.05 in the sham acupuncture group. The between-group differences in the primary outcome measures posttreatment were statistically significant. However, no differences were found between the two groups during the two follow-ups. Regarding the PSG data, there were significantly lower levels of sleep onset latency (SOL), a lower percentage of sleep stage N1 and a higher percentage of sleep stage N3 in the acupuncture group than in the sham acupuncture group. After treatment, there were lower levels of comorbid symptoms (BAI, BDI, FSS and ESS) in both groups. However, no significant differences were observed between the groups.

CONCLUSION

Acupuncture at HT 7 and KI 7 is an effective and safe nonpharmacologic intervention option for chronic insomnia.

Multi-Scale Permutation Entropy: A Potential Measure for the Impact of Sleep Medication on Brain Dynamics of Patients with Insomnia

Insomnia is a common sleep disorder that is closely associated with the occurrence and deterioration of cardiovascular disease, depression and other diseases. The evaluation of pharmacological treatments for insomnia brings significant clinical implications. In this study, a total of 20 patients with mild insomnia and 75 healthy subjects as controls (HC) were included to explore alterations of electroencephalogram (EEG) complexity associated with insomnia and its pharmacological treatment by using multi-scale permutation entropy (MPE). All participants were recorded for two nights of polysomnography (PSG). The patients with mild insomnia received a placebo on the first night (Placebo) and temazepam on the second night (Temazepam), while the HCs had no sleep-related medication intake for either night. EEG recordings from each night were extracted and analyzed using MPE. The results showed that MPE decreased significantly from pre-lights-off to the period during sleep transition and then to the period after sleep onset, and also during the deepening of sleep stage in the HC group. Furthermore, results from the insomnia subjects showed that MPE values were significantly lower for the Temazepam night compared to MPE values for the Placebo night. Moreover, MPE values for the Temazepam night showed no correlation with age or gender. Our results indicated that EEG complexity, measured by MPE, may be utilized as an alternative approach to measure the impact of sleep medication on brain dynamics.
