RESUMEN
Importance: The effects of self-administered acupressure (SAA) on knee osteoarthritis (OA) pain remain unclear. Objective: To evaluate the effectiveness of SAA taught via a short training course on reducing knee OA pain in middle-aged and older adults. Design, Setting, and Participants: This randomized clinical trial was conducted among community-dwelling individuals in Hong Kong who were aged 50 years or older with probable knee OA from September 2019 to May 2022. Interventions: The intervention included 2 training sessions for SAA with a brief knee health education (KHE) session, in which participants practiced acupressure twice daily for 12 weeks. The control group (KHE only) received only education about maintaining knee health on the same schedule and duration. Main Outcomes and Measures: The primary outcome was the numerical rating scale (NRS) pain score at 12 weeks. Other outcomes included Western Ontario and McMaster University Osteoarthritis Index, Short Form 6 Dimensions (SF-6D), Timed Up and Go, and Fast Gait Speed tests. Results: A total of 314 participants (mean [SD] age, 62.7 [4.5] years; 246 [78.3%] female; mean [SD] knee pain duration, 7.3 [7.6] years) were randomized into intervention and KHE-only groups (each 157). At week 12, compared with the KHE-only group, the intervention group had a significantly greater reduction in NRS pain score (mean difference [MD], -0.54 points; 95% CI, -0.97 to -0.10 points; P = .02) and higher enhancement in SF-6D utility score (MD, 0.03 points; 95% CI, 0.003 to 0.01 points; P = .03) but did not have significant differences in other outcome measures. The cost-effectiveness acceptability curve demonstrated a greater than 90% probability that the intervention is cost-effective at a willingness to pay threshold of 1 GDP per capita. Conclusions and Relevance: In this randomized clinical trial, SAA with a brief KHE program was efficacious and cost-effective in relieving knee pain and improving mobility in middle-aged and older adults with probable knee OA.

BACKGROUND: Insomnia is a significant health problem in the community. Self-administered acupressure (SAA) may be an alternative strategy to alleviate insomnia. PURPOSE: This study is the first to investigate the effects of SAA delivered through a training course in alleviating insomnia disorder compared with sleep hygiene education (SHE). METHODS: A randomized controlled trial was conducted on 200 participants with insomnia disorder. The eligible participants were randomized into the SAA or SHE group. Both groups attended the allocated training courses (two sessions, 2 h each) and then were followed up at weeks 4 and 8. The primary outcome was the severity of insomnia symptoms and related daytime impairment as measured by the Insomnia Severity Index (ISI). Other measures included a 7-day sleep diary and actigraphy, Hospital Anxiety and Depression Scale (HADS), and Short-Form Six-Dimension (SF6D). RESULTS: The SAA group showed a significantly greater improvement in ISI score than the SHE group at week 4 (mean difference: -1.89 units, 95% CI: 0.85, 2.93; Cohen's d = 0.51, p < 0.001) and week 8 (mean difference: -2.89 units, 95% CI: 1.67, 4.11; d = 0.67, p < 0.001). In addition, the SAA group showed a greater reduction in the HADS anxiety score and HADS depression score and increase in SF6D at week 8. CONCLUSIONS: SAA taught in a short training course is a feasible and effective approach to improve sleep and related daytime impairment and mood problems in individuals with insomnia disorder.
RESUMEN
BACKGROUND: Acupuncture is an alternative treatment for improving sleep, and it may attenuate oxidative stress, which is a possible pathophysiological factor in insomnia. The aim of this study was to examine the efficacy and safety of a semi-individualized acupuncture in improving sleep and explore its effect on oxidative stress parameters in adults with insomnia disorder. METHODS: In this randomized sham-controlled trial, 140 participants were randomly assigned to either a 4-week semi-individualized traditional acupuncture (TA) or noninvasive sham acupuncture (SA). The primary outcome measure was the sleep-diary-derived sleep efficiency. Other outcomes included sleep diary and actigraphy, Insomnia Severity Index, anxiety and depressive symptoms, and quality of life. Blood samples were taken to measure oxidative stress parameters (malondialdehyde, glutathione peroxidase, paraoxonase, and arylesterase). RESULTS: Although no significant difference was found in the primary outcome measure, both sleep-diary-derived and actigraphy-derived total sleep time (TST) were significantly increased in the TA group at 1-week posttreatment (mean difference in sleep diary = 22.0 min, p = 0.01, actigraphy = 18.8 min, p = 0.02). At 5-week posttreatment follow-up, a significantly higher proportion of participants in the TA group showed sleep-diary-derived sleep efficiency (SE) ≥ 85% than in the SA group (55.6% versus 36.4%, p = 0.03). CONCLUSION: TA and SA did not significantly differ in improving subjective sleep efficiency in individuals with insomnia disorder. However, the TA group showed a short-term effect on improving TST as measured by both sleep diary and actigraphy at 1-week posttreatment, but there were no differences in the oxidative stress parameters.

RESUMEN
Chemotherapy causes various side effects, including cognitive impairment, known as 'chemobrain'. In this study, we determined whether a novel acupuncture mode called electroacupuncture trigeminal nerve stimulation plus body acupuncture (EA/TNS + BA) could produce better outcomes than minimum acupuncture stimulation (MAS) as controls in treating chemobrain and other symptoms in breast cancer patients. In this assessor- and participant-blinded, randomized controlled trial, 93 breast cancer patients under or post chemotherapy were randomly assigned to EA/TNS + BA (n = 46) and MAS (n = 47) for 2 sessions per week over 8 weeks. The Montreal Cognitive Assessment (MoCA) served as the primary outcome. Digit span test was the secondary outcomes for attentional function and working memory. The quality of life and multiple functional assessments were also evaluated. EA/TNS + BA treated group had much better performance than MAS-treated group on reverse digit span test at Week 2 and Week 8, with medium effect sizes of 0.53 and 0.48, respectively, although no significant differences were observed in MoCA score and prevalence of chemobrain between the two groups. EA/TNS + BA also markedly reduced incidences of diarrhoea, poor appetite, headache, anxiety, and irritation, and improved social/family and emotional wellbeing compared to MAS. These results suggest that EA/TNS + BA may have particular benefits in reducing chemotherapy-induced working memory impairment and the incidence of certain digestive, neurological, and distress-related symptoms. It could serve as an effective intervention for breast cancer patients under and post chemotherapy (trial registration: https://www.clinicaltrials.gov: NCT02457039).

OBJECTIVE: To evaluate the efficacy of using electroacupuncture as an adjunct treatment in enhancing the benzodiazepine cessation rate in long-term benzodiazepine users. METHODS: This was a randomized, assessor- and subject-blinded, controlled trial. One hundred and forty-four long-term benzodiazepine users were randomly assigned to receive either electroacupuncture or placebo acupuncture (a sham itervention using non-invasive placebo needles) combined with a gradual benzodiazepine tapering schedule for 4 weeks. The primary outcome was the cessation rate of benzodiazepine use. Subjects were assessed on their benzodiazepine usage, benzodiazepine withdrawal symptoms, insomnia severity, and anxiety and depressive symptoms at baseline, week 6 and week 16. RESULTS: The cessation rates of the electroacupuncture and placebo acupuncture groups at 12 weeks post-treatment were 9.17% and 10.83%, respectively. Both groups showed a reduction in benzodiazepine usage by a self-completed drug record at week 16 (compared to baseline: electroacupuncture group -40.23% versus placebo acupuncture group -48.76%). However, no significant between-group differences were found in the benzodiazepine cessation rate, reduction in benzodiazepine usage, and other secondary measures across all the study time points. CONCLUSIONS: Electroacupuncture showed a similar cessation rate in benzodiazepine use to that of non-invasive placebo acupuncture in long-term users during a 4-week gradual tapering schedule. The evidence did not support advantages of electroacupuncture over non-invasive placebo acupuncture on reducing insomnia, anxiety, depression, or other withdrawal symptoms during the gradual tapering schedule. Despite a 40% decrease in the benzodiazepine usage in both groups, the effects may be attributed to the non-specific effects of acupuncture. TRIAL REGISTRATION: ClinicalTrials.gov # NCT02475538.

Self-administered acupressure has potential as a low-cost alternative treatment for insomnia. To evaluate the short-term effects of self-administered acupressure for alleviating insomnia, a pilot randomized controlled trial was conducted. Thirty-one subjects (mean age: 53.2 years; 77.4% female) with insomnia disorder were recruited from a community. The participants were randomized to receive two lessons on either self-administered acupressure or sleep hygiene education. The subjects in the self-administered acupressure group (n = 15) were taught to practise self-administered acupressure daily for 4 weeks. The subjects in the comparison group (n = 16) were advised to follow sleep hygiene education. The primary outcome was the Insomnia Severity Index (ISI). Other measures included a sleep diary, Hospital Anxiety and Depression Scale and Short-form Six-Dimension. The subjects in the self-administered acupressure group had a significantly lower ISI score than the subjects in the sleep hygiene education group at week 8 (effect size = 0.56, P = 0.03). However, this observed group difference did not reach a statistically significant level after Bonferroni correction. With regard to the secondary outcomes, moderate between-group effect sizes were observed in sleep onset latency and wake after sleep onset based on the sleep diary, although the differences were not significant. The adherence to self-administered acupressure practice was satisfactory, with 92.3% of the subjects who completed the lessons still practising acupressure at week 8. In conclusion, self-administered acupressure taught in a short training course may be a feasible approach to improve insomnia. Further fully powered confirmatory trials are warranted.

BACKGROUND: Conventional approaches for benzodiazepine tapering have their limitations. Anecdotal studies have shown that acupuncture is a potential treatment for facilitating successful benzodiazepine tapering. As of today, there was no randomized controlled trial examining its efficacy and safety. The purpose of the study is to evaluate the efficacy of using electroacupuncture as an adjunct treatment to gradual tapering of benzodiazepine doses in complete benzodiazepine cessation in long-term benzodiazepine users. METHODS/DESIGN: The study protocol of a randomized, assessor- and subject-blinded, controlled trial is presented. One hundred and forty-four patients with histories of using benzodiazepines in ≥50% of days for more than 3 months will be randomly assigned in a 1:1 ratio to receive either electroacupuncture or placebo electroacupuncture combined with gradual benzodiazepine tapering schedule. Both experimental and placebo treatments will be delivered twice per week for 4 weeks. Major assessments will be conducted at baseline, week 6 and week 16 post-randomization. Primary outcome is the cessation rate of benzodiazepine use. Secondary outcomes include the percentage change in the doses of benzodiazepine usage and the severity of withdrawal symptoms experienced based on the Benzodiazepine Withdrawal Symptom Questionnaire, insomnia as measured by the Insomnia Severity Index, and anxiety and depressive symptoms as evaluated by the Hospital Anxiety and Depression Scale. Adverse events will also be measured at each study visit. DISCUSSION: Results of this study will provide high quality evidence of the efficacy and safety of electroacupuncture as an adjunct treatment for benzodiazepine tapering in long-term users.

OBJECTIVE: To examine the prevalence and utilization pattern of complementary and alternative medicine (CAM) for insomnia in Hong Kong. METHODS: Respondents were selected from the general population and interviewed by telephone Their sleep was assessed by a Chinese version of the Brief Insomnia Questionnaire (BIQ) and CAM use by a checklist. Prevalence findings were weighted by the BIQ insomnia diagnosis, age, and sex. RESULTS: 402 respondents completed the survey. The population-weighted prevalence of any treatment in the past 12 months was 21.3%, any CAM use at 12.3%, any conventional treatment at 6.5%, and alcohol use at 1.6%; however, 46.6% of the BIQ insomnia cases did not seek treatment. The most commonly used CAM modalities was Chinese herbal medicine (7.9%), followed by acupuncture (1.7%) and Western herbal products (1.7%). Most CAM therapies were used infrequently and without consultation of healthcare professionals. Only BIQ insomnia diagnosis and being female were found predictive of CAM use. CONCLUSIONS: Apart from Chinese herbal medicine and acupuncture, the use of conventional treatments, CAM, and alcohol for trouble sleeping was all less common in Hong Kong. Public education on the consequences of insomnia and various treatment modalities is needed.

STUDY OBJECTIVES: To evaluate the efficacy and safety of electroacupuncture as an additional treatment for residual insomnia associated with major depressive disorder (MDD). DESIGN: Randomized, placebo-controlled. SETTING: A psychiatric outpatient clinic. PARTICIPANTS: 78 Chinese patients with DSM-IV-diagnosed MDD, insomnia complaint, a Hamilton Rating Scale for Depression (HDRS(17)) score ≤ 18, and fixed antidepressant dosage. INTERVENTION: Electroacupuncture, minimal acupuncture (superficial needling at non-acupuncture points), or noninvasive placebo acupuncture 3 sessions weekly for 3 weeks. MEASUREMENTS AND RESULTS: Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), HDRS(17), 1 week sleep diaries, and 3 day actigraphy were administered at baseline, 1 week post-treatment, and 4 week post-treatment. There was significant group by time interaction in ISI, PSQI, and sleep diary-derived sleep efficiency (mixed-effects models, P = 0.04, P = 0.03, and P = 0.01, respectively). Post hoc pairwise comparisons revealed that electroacupuncture and minimal acupuncture were more efficacious than placebo acupuncture in ISI and PSQI at 1 week and 4 week post-treatment. Minimal acupuncture resulted in greater improvement in sleep diary-derived sleep efficiency than placebo acupuncture at 1 week post-treatment. There was no significant between-group difference in actigraphy measures, depressive symptoms, daily functioning, and hypnotic consumption, and no difference in any measures between electroacupuncture and minimal acupuncture. CONCLUSION: Compared with placebo acupuncture, electroacupuncture and minimal acupuncture resulted in greater improvement in subjective sleep measures at 1 week and 4 week post-treatment. No significant difference was found between electroacupuncture and minimal acupuncture, suggesting that the observed differences could be due to nonspecific effects of needling, regardless of whether it is done according to traditional Chinese medicine theory.

BACKGROUND: Herb-drug interactions are an important issue in drug safety and clinical practice. The aim of this epidemiological study was to characterize associations of clinical outcomes with concomitant herbal and antipsychotic use in patients with schizophrenia. METHODS AND FINDINGS: In this retrospective, cross-sectional study, 1795 patients with schizophrenia who were randomly selected from 17 psychiatric hospitals in China were interviewed face-to-face using a structured questionnaire. Association analyses were conducted to examine correlates between Chinese medicine (CM) use and demographic, clinical variables, antipsychotic medication mode, and clinical outcomes. The prevalence of concomitant CM and antipsychotic treatment was 36.4% [95% confidence interval (95% CI) 34.2%-38.6%]. Patients using concomitant CM had a significantly greater chance of improved outcomes than non-CM use (61.1% vs. 34.3%, ORâ=â3.44, 95% CI 2.80-4.24). However, a small but significant number of patients treated concomitantly with CM had a greater risk of developing worse outcomes (7.2% vs. 4.4%, ORâ=â2.06, 95% CI 2.06-4.83). Significant predictors for concomitant CM treatment-associated outcomes were residence in urban areas, paranoid psychosis, and exceeding 3 months of CM use. Herbal medicine regimens containing Radix Bupleuri, Fructus Gardenia, Fructus Schisandrae, Radix Rehmanniae, Akebia Caulis, and Semen Plantaginis in concomitant use with quetiapine, clozapine, and olanzepine were associated with nearly 60% of the risk of adverse outcomes. CONCLUSIONS: Concomitant herbal and antipsychotic treatment could produce either beneficial or adverse clinical effects in schizophrenic population. Potential herb-drug pharmacokinetic interactions need to be further evaluated.
