RESUMEN
BACKGROUND: Sinew acupuncture is a new modality of acupuncture in which needles are inserted into acupoints, ashi points or spasm points of sinew and muscles along the meridian sinew pathway. A previous observational study revealed that sinew acupuncture has immediate analgesic effects on various soft tissue injuries, including knee injuries. However, no rigorous trials have been conducted. This study aims to examine whether sinew acupuncture can safely relieve pain and symptoms of knee osteoarthritis (KOA) and improve patients' functional movement and quality of life. METHODS/DESIGN: A randomized, sham-controlled, patient- and assessor-blinded trial will be conducted to compare the efficacy of sinew acupuncture and sham acupuncture. Subjects will be assessed by the physician and acupuncturists. A sample of eighty-six eligible subjects will be randomized into either the sinew acupuncture group or the sham acupuncture group. The intervention will be performed in the Hong Kong Tuberculosis Association Chinese Medicine Clinic cum Training Centre of the University of Hong Kong by acupuncturists with over 3 years of acupuncture experience. Subjects will receive 10 sessions of interventions for 4 weeks, followed by a 6-week follow-up. The visual analogue scale (VAS) score at week 4 will be the primary outcome. The Western Ontario and McMasters University Osteoarthritis Index (WOMAC), Timed Up & Go Test (TUG), 8-step Stair Climb Test (SCT) and the 36-Item Short Form Survey (SF-36) will be secondary outcomes. DISCUSSION: Sinew acupuncture is a potential alternative non-pharmacological therapy for KOA. This rigorous trial will expand our knowledge of whether sinew acupuncture reduces pain intensity and improves symptoms, functional movements, and quality of life of KOA patients. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (Identifier: NCT03099317) in March 2017.

BACKGROUND: The concurrent use of conventional drugs and herbal medicines is becoming popular among patients with cancer. However, the potential risk of herb-drug interactions (HDI) remains under-addressed in the literature. Previous reviews have mainly focused on the prevalence of interactions, with less attention paid to the methods used by pharmacoepidemiological studies on evaluating HDI. This scoping review aims to summarize the existing pharmacoepidemiological studies that evaluate HDI using real-world data and to identify gaps to be addressed in future research. METHODS: A comprehensive search was performed in nine English- and Chinese-language databases from their inception to May 2021. Gray literature and manual searches were conducted to identify additional studies. The recommended components of the pharmacoepidemiological studies and key findings related to HDI were summarized. The proportion (%) of patients with cancer at risk of HDI was estimated by combining data from eligible studies. RESULTS: Twenty-eight studies were included in the review. More than half of these studies were cross-sectional studies (n = 18, 64.3%), followed by retrospective cohort studies (n = 5, 17.9%) and prospective cohort studies (n = 2, 7.1%). The three cancer drugs most commonly studied for their interaction potential with herbs were tamoxifen (n = 11, 39.3%), cyclophosphamide (n = 6, 21.4%), and paclitaxel (n = 6, 21.4%). Most cross-sectional studies identified potential HDI using tertiary databases and primary literature searches. Conversely, prospective and retrospective studies mainly investigated actual clinical outcomes, such as adverse events and secondary cancer occurrences. Most interaction outcomes identified using real-world data did not lead to negative clinical consequences. Collectively, 45.4% of herbal medicine users of the included studies were found to be at risk of HDI. We infer from this review that the common limitations of these studies were limited sample size, lack of data on herbal medicine use and details of HDI, and lack of evidence of HDI. Based on the study limitations, several recommendations to enrich the data sources and optimize the study designs were proposed. CONCLUSIONS: There is a high demand for pharmacoepidemiological research on HDI, considering the increasing popularity of herbal medicine among patients with cancer. It is anticipated that emerging real-world data in this field can guide the development of safe and effective approaches to integrative oncology.

Background: Existing educational programs typically include limited information on traditional, complementary, and integrative medicine (TCIM) for survivors of childhood cancer. Objectives: This brief report presents the preliminary results of an educational program that aims to promote the safe and effective use of Chinese medicine (CM) among survivors in Hong Kong. Methods: Survivors of childhood cancer, their caregivers, and oncology practitioners were invited to participate in a program that consists of two didactic seminars and a written educational booklet that disseminated information on the use of CM. A structured questionnaire was used to evaluate participants' receptivity toward and perceived relevance of the program. The Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework was used to discuss the impact of the intervention. Results: Reach: A total of 174 participants attended the seminars, and the seminar recording received over 380 views on social media platforms since April 2021. The hardcopy of the educational booklet was distributed to 43 recipients. The web-version of the booklet was sent to 67 participants and downloaded 143 times. Efficacy: The majority found that the content of the seminar useful (mean score = 5.04/6 points), especially the CM exercise (mean score = 4.88/6 points) and dietary advice (mean score = 4.99/6 points). Intention to adopt: The survivors (or their caregivers) reported that they would adopt advice on food therapies (83.3%) and traditional Chinese health exercises (55.6%) during survivorship. Conclusion: The preliminary data on patient preferences will be applied to further develop educational materials and to establish a TCIM referral network within the cancer survivor community.
RESUMEN
BACKGROUND: Acupuncture has been an alternative approach for pain management, but trial evidence is conflicting. METHODS: Eighty-six patients with knee osteoarthritis were randomly assigned in a 1:1 ratio from June 14, 2017, to January 20, 2019, to receive either superficial needling acupuncture treatment or sham acupuncture for 10 sessions over a 4-week treatment period, followed by a 6-week follow-up period. The primary outcome was the change of pain intensity at week 4 measured using a 100-mm visual analogue scale. Secondary outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index and 36-Item Short Form Health Survey. RESULTS: At the end of the 4-week treatment period, mean changes in the visual analogue scale were -30.8 (95% confidence interval [CI], -38.2 to -23.0; p <.001) in the acupuncture group and -26.7 (95% CI, -34.4 to -18.8; P <.001) in the sham group. The difference between the acupuncture group and the sham group was -4.1 (95% CI, -14.4 to 6.2; P = 0.431). At week 10, the difference between the groups was -2.2 (95% CI, -13.1 to 8.8; P =0.699). There was no statistically significant difference in Western Ontario and McMaster Universities Osteoarthritis Index subscores (pain, stiffness, and physical function) and 36-Item Short Form Health Survey-related outcomes across groups from weeks 2 to 10. The incidence of treatment-related adverse events was 4.4% in the acupuncture group and 0.8% in the sham acupuncture group. All adverse events were classified as mild. CONCLUSION: Acupuncture for 4 weeks is not superior to non-penetrating sham acupuncture. The current study cannot confirm that superficial acupuncture has efficacy for the treatment of knee osteoarthritis.
