Publication Trends in Acupuncture Research: A 20-Year Bibliometric Analysis Based on PubMed

A comprehensive overview of acupuncture therapy over the past 20 years: Machine learning-based bibliometric analysis

BACKGROUND

Acupuncture, a therapy created by the ancient Chinese, has been gaining increasing popularity and acceptance worldwid. The surge in the number of publications on acupuncture therapy has posed significant challenges for researchers in effectively managing the vast amount of information. This study aimed to analyze the themes and topics of the scientific publications related to acupuncture therapy in the past two decades by machine learning.

METHODS

The MeSH term "Acupuncture Therapy" was used for searching publications from 1st January, 2004-31 st December, 2023 on the PubMed database, while the R platform was adopted to obtain associated data. A topic network was constructed by latent Dirichlet allocation (LDA) and the Louvain algorithm.

RESULTS

A total of 17,584 publications were finally recruited in this article. The publications were derived from 57 countries, with China, The United States and England being the top three countries. "Acupuncture Points", "Treatment outcome", "Electroacupuncture" were the most concerned MeSH terms. Four clusters and 50 branched topics were recognized by LDA and network analyses. "Comparative Efficacy", "Biochemical Analysis", "Symptomatic Treatment", "Professional Practice" and "Clinical Trials" are hotspots identified by LDA. "Neurotransmitter", "Meta-Analysis" and "Literature Review" have presented as new research hotspots.

CONCLUSIONS

Acupuncture therapy has obtained increasing attention over the past two decades. Most of the studies focus on the mechanisms especially the analgesic and anti-inflammatory mechanisms, more researches such as "Neurotransmitter" will continue to advance. Besides, "meta-analysis" and "literature reviews" are increasingly common, providing more comprehensive and credible evidence for acupuncture therapy.

Research hotspots and trends of acupoint and pain based on PubMed: a bibliometric analysis

Objective

Acupoint-related interventions are the widely utilized modalities in traditional Chinese medicine for the alleviation of pain. This study aims to identify research hotspots and trends by conducting a bibliometric analysis of the relevant literature on acupoint and pain, thereby elucidating future research directions in this field.

Method

A comprehensive search was conducted on PubMed for literature pertaining to acupoint and pain from January 2010 to August 2024. Subsequent bibliometric analyses, encompassing statistical evaluation of bibliographic data, keyword cluster analysis, and co-occurrence analysis, were conducted utilizing the Medpulse database and the Bibliometrix R-package.

Results

A total of 742 articles from 179 journals were included in the analysis, with the majority focusing on complementary and alternative medicine or comprehensive research. The number of publications in this field has shown a consistent annual increase, involving contributions from 19 different countries of corresponding authors. China had the greatest contribution with 407 articles followed by Korea with 25 articles. The leading institutions in terms of publication volume are Chengdu University of Traditional Chinese Medicine, China Medical University, and Kyung Hee University. The topics covered in these articles include acupuncture, transcutaneous electrical acupoint stimulation (TEAS), randomized controlled trials, analgesia, zusanli (st36), systematic review, and anxiety, among others. The main cluster themes are intervention methods for various acupoints and the assessment of their efficacy.

Conclusion

The bibliometric analysis has identified the intervention methods of acupoints and the evaluation of their efficacy in pain management as emerging research focal points. Additionally, anxiety is anticipated to emerge as a future research direction within this domain.

"Bringing greater research fluency into our educational vision": A qualitative research study on improving Traditional Chinese Medicine research education

The main objective of this qualitative analysis is to increase the quality of Traditional Chinese Medicine (TCM) research education. Subject matter experts and stakeholders were sent a list of possible topics to include in a research course and were asked to comment on it, add or subtract topics, and suggest appropriate research papers to use, lessons learned in their topic areas and possible stand-alone topics for inclusion in other courses. Their feedback was used to revise the topic list, create a list of foundational research papers to include in a research course and devise a list of stand-alone topics that could be included in the general TCM research curriculum. The result is a TCM research course curriculum that will improve the teaching of evidence-based medicine (EBM) practices to TCM students. This will help TCM faculty and program directors improve existing courses, develop new courses and strengthen EBM education.

This study offers insights into traditional Chinese non-pharmacological therapies in weight management, and may benefit further research.

Validity of data extraction in acupuncture meta-analysis: a reproducibility study protocol

INTRODUCTION

Systematic review and meta-analysis occupy the apex of the evidence pyramid, serving as the most comprehensive and reliable form of evidence-based assessment. Data extraction is a crucial juncture in meta-analysis, establishing the underpinnings for the outcomes and deductions drawn from systematic reviews (SRs). However, the frequency of data extraction errors in meta-analysis is quite significant. Data extraction errors can lead to biased study results, affect the credibility of study results and even mislead clinical practice. The quantity of acupuncture randomised controlled trials and SRs has expanded rapidly recently, yet the validity of data extraction remains unexplored. Hence, our study aims to investigate the validity of data extraction errors in acupuncture SRs, the effect of data extraction errors on results and the relevant guidelines used erroneous results.

METHODS AND ANALYSIS

Four databases including MEDLINE, Web of Science, Cochrane linbrary and EMBASE will be searched from 1 January 2019 to 31 December 2023 for acupuncture SRs. Two researchers will independently extract data from the meta-analysis and the original study into a standardised data extraction table. A senior investigator, who did not participate in the data extraction process, will verify the results. In cases of discrepancies, the senior researcher will conduct further extraction and consult with another senior researcher to determine the final results. We will analyse the frequency and type of data extraction errors and data estimation errors and evaluate the effect of data extraction errors on results. Quantile regression will be used to explore the factors influencing data extraction error frequency at 25th, 50th and 75th percentiles. Finally, we will further search for guidelines used erroneous results.

ETHICS AND DISSEMINATION

Ethical approval is not necessary for this study. This protocol has been registered in Open Science Framework Registries. REGISTRATION DOI: https://doi.org/10.17605/OSF.IO/CHMPA.

Assessment of acupuncture's effectiveness in mitigating fatigue among patients afflicted with multiple sclerosis: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Fatigue is a pervasive and debilitating symptom of multiple sclerosis (MS) that severely impairs quality of life and daily functioning. This emphasizes the essential need for complementary therapies that go beyond conventional therapies. Although acupuncture is gaining popularity in MS management, there is a critical lack of rigorous research on its effectiveness in alleviating symptoms.

METHODS

A comprehensive literature search was conducted across multiple databases, focusing on studies evaluating acupuncture's effectiveness in alleviating fatigue in MS patients. Key outcomes measured in the analysis included fatigue, quality of life, and disability.

RESULTS

Six studies were included in the analysis, consisting of two observational studies and four randomized controlled trials. The analysis focused on evaluating acupuncture's efficacy in alleviating fatigue induced by MS. Despite variations in acupuncture protocols, outcome metrics, and control conditions, our meta-analysis revealed that acupuncture significantly reduces fatigue (MD: -0.92, 95 % CI: -1.36 to -0.47, p < 0.0001) and enhances quality of life (SMD: 0.91, 95 % CI: 0.07-1.74, p = 0.03), underscoring its potential as a therapeutic intervention in the management of MS.

CONCLUSION

The meta-analysis suggests a notable improvement in MS-related fatigue following acupuncture, both compared to controls and pre-treatment levels, positioning it as a potential adjunct therapy. However, the prevalent risk of bias in these studies necessitates further high-quality research, along with studies involving larger patient cohorts, to definitively ascertain acupuncture's efficacy and safety in this context.

Needles, Herbs, and Electricity: A Meta-Analysis of Traditional Eastern Medicine in the Management of Facial Paralysis

In Eastern nations, interventions like acupuncture and herbal medicine are often first-line for patients presenting with facial paralysis. Despite the rising popularity of Eastern medicine in Western nations, the literature assessing whether Eastern medicine interventions should be recommended for patients with facial paralysis is lacking. This meta-analysis aims to define what Eastern medicine interventions exist for the management of facial paralysis and assess whether current research supports these approaches as safe and effective. The PubMed and Cochrane databases were reviewed in accordance with PRISMA guidelines. Inclusion criteria consisted of peer-reviewed studies published between 2000 and 2023 that reported on Eastern medicine, also described as, "complementary" or "alternative" interventions for facial paralysis. Effective and cured rates were the primary outcomes extracted from the literature. Interventions within these studies were categorized into six groups: (1) standard acupuncture, (2) special needle therapies, (3) needle therapy + other alternative treatments, (4) herbal medicine, (5) alternative treatments + Western medicine, and (6) Western medicine alone. A multiple-treatment meta-analysis was performed to assess differences in effective and cured rates. Fifteen studies involving Eastern medicine for the treatment of facial paralysis met the inclusion criteria. No significant differences were found in effective and cured rates across groups. Multiple quality concerns were noted, such as the lack of control groups, blinding, and randomization noted in several studies. Many studies failed to report complications, preventing conclusions from being drawn on the safety of these Eastern medicine interventions. This meta-analysis was unable to support the recommendation of Eastern medicine approaches for patients with facial paralysis. No Eastern medicine treatments, combination of Eastern medicine treatments, or Eastern medicine treatments given with Western medicine were seen to be more effective than Western medicine alone.

Assessing the role and impact of research in clinical practice among acupuncturists in western countries: a multinational cross-sectional survey

Background

Evidence-informed practice is crucial to perform safe and efficient health interventions. In recent years, the evidence base of acupuncture continuously increased leading to the integration of acupuncture into clinical guidelines by various leading medical associations worldwide. At the same time, recent studies showed that licensed acupuncturists are rarely utilizing scientific research to inform their practice.

Methods

This descriptive study using an online survey assessed the role of evidence-informed practice of acupuncturists in Austria, Germany, the United States of America, Australia, and New Zealand and aimed to determine critical factors relevant for promoting research literacy including demographical data, data about the clinical practice patterns, and the role and value of different information sources of traditional, complementary and integrative medicine (TCIM) practitioners.

Results

In total, 404 acupuncturists completed the online survey that included questions about demographic characteristics, the role and value of research in clinical practice, and details about the amount and type of continuing professional education. Univariate and multivariate analysis was used to determine significant predictors of the outcome variable "importance of research in clinical practice" (numerical rating scale, 0 to 100). The results showed that the majority of acupuncturists use certified courses as primary source of continuing professional education and value experts' opinions as the most reliable source of information. Multivariate analysis showed that the importance of research is dependent on the interest in research, an interdisciplinary learning environment, and positive experiences with research including if an acupuncture study ever changed the clinical practice of practitioners.

Conclusion

Future educational programs should therefore focus on an interactive format aiming to promote skills to critically assess the value and practical use of research studies to improve the general practice of acupuncture.

Protocol for a scoping review of traditional medicine research methods, methodologies, frameworks and strategies

Background

The World Health Organization (WHO) has called for the evidence-informed integration of traditional medicine (TM) into health systems. Research rigor requires a good "fit" between research designs and what is being studied. The expectation that TM research fully adheres to biomedical evidentiary norms potentially creates tensions, as TM paradigms have their own distinct features. A scoping review will be conducted to describe and characterize the research approaches used in TM and their paradigmatic alignment with the TM being studied.

Methods

This scoping review protocol was informed by Joanna Briggs Institute (JBI) methods. This protocol outlines an a priori conceptual framework, provisionally termed "paradigmatic alignment." The review will include all populations, TM types, research approaches (i.e., methods, methodologies, frameworks, strategies), cultural contexts, and health care settings. Up to 38 English and non-English language databases will be searched sequentially for both published and gray literature until reaching data saturation across relevant concepts and contexts. Analysis will begin deductively, using a pre-piloted data extraction template to describe the TM research approaches. A basic qualitative content analysis of a sample of evidence sources will explore how research approaches are applied or modified to align with the TM therapeutic paradigm, and the manner in which they co-exist, contrast, complement or align with established biomedical research approaches. The findings will be narrated and summarized in charting tables and figures. The review will be reported according to the PRISMA scoping review extension. Consultative engagement with knowledge users across all review stages is planned.

Discussion

Aligned with the principle of Two-Eyed Seeing (Etuaptmumk), wherein Indigenous/traditional and biomedical knowledges may equitably co-exist, this review promises to advance scholarly insights of critical value in an increasingly pluralistic, globalized world.Clinical trial registration: https://clinicaltrials.gov/, identifier INPLASY2023110071.

Mechanistic study of acupuncture on the pterygopalatine ganglion to improve allergic rhinitis: analysis of multi-target effects based on bioinformatics/network topology strategie

One of the prevalent chronic inflammatory disorders of the nasal mucosa, allergic rhinitis (AR) has become more widespread in recent years. Acupuncture pterygopalatine ganglion (aPPG) is an emerging alternative therapy that is used to treat AR, but the molecular mechanisms underlying its anti-inflammatory effects are unclear. This work methodically demonstrated the multi-target mechanisms of aPPG in treating AR based on bioinformatics/topology using techniques including text mining, bioinformatics, and network topology, among others. A total of 16 active biomarkers and 108 protein targets related to aPPG treatment of AR were obtained. A total of 345 Gene Ontology terms related to aPPG of AR were identified, and 135 pathways were screened based on Kyoto Encyclopedia of Genes and Genomes analysis. Our study revealed for the first time the multi-targeted mechanism of action of aPPG in the treatment of AR. In animal experiments, aPPG ameliorated rhinitis symptoms in OVA-induced AR rats; decreased serum immunoglobulin E, OVA-sIgE, and substance P levels; elevated serum neuropeptide Y levels; and modulated serum Th1/Th2/Treg/Th17 cytokine expression by a mechanism that may be related to the inhibition of activation of the TLR4/NF-κB/NLRP3 signaling pathway. In vivo animal experiments once again validated the results of the bioinformatics analysis. This study revealed a possible multi-target mechanism of action between aPPG and AR, provided new insights into the potential pathogenesis of AR, and proved that aPPG was a promising complementary alternative therapy for the treatment of AR.

Research trends on acupuncture for neuropathic pain: A bibliometric analysis from 1979 to 2023

BACKGROUND

Acupuncture has drawn increasing attention as a complementary and alternative therapy for neuropathic pain (NP). The present study aimed to summarize the current status and research trends on acupuncture for NP over the past several decades.

METHODS

The publications on acupuncture for NP in the database of Web of Science Core Collection from 1979 to 2023 were searched. VOSviewer (1.6.15) and CiteSpace software (5.5.R2) were applied to identify active authors, journals, countries and institutions, co-cited references and hot keywords.

RESULTS

A total of 642 publications were finally included, and the quantitative trend of annual publications on acupuncture for NP have shown overall upward from 1979 to 2023. Peoples R China was the most productive and influential country, while Kyung Hee University from South Korea was both the first in publications and citations. Fang JQ ranked the first productive author and Han JS was the first 1 among the co-cited authors. The first productive journal was Evidence-based Complementary and Alternative Medicine, while the first co-cited journal was Pain. The high-frequency keywords were divided into 9 clusters, and the frontier topic focused on "Chronic pain".

CONCLUSION

This present study visually showed the research status and trends of acupuncture for NP from 1979 to 2023 on the basis of bibliometric analysis, which may in some way help researcher discovery and explore some new research directions and ideas in the future.

Global trends of acupuncture clinical research on analgesia from 2010 to 2023: a bibliometric and visualization analysis

Objective

Acupuncture, acknowledged as a potent non-pharmacological therapy, is frequently employed to alleviate pain. Despite its widespread use, there has been a lack of overarching bibliometric analysis of clinical research on acupuncture analgesia. We aimed to summarize current patterns, hotspots, and development trends in this field through bibliometric analysis.

Methods

This study evaluates academic publications retrieved from the Web of Science database (2010.01-2023.09) concerning acupuncture analgesia in clinical settings. All primary and secondary studies on humans were included. To track global developmental trends, we employed several software for analyzing annual publication volumes, countries/regions, institutions, authors, cited authors, journals, cited journals, references, and keywords and to draw collaborative networks and reference co-citation network maps.

Results

The final search encompassed 7,190 relevant studies, including 1,263 randomized controlled trials (RCTs) and 1,293 systematic reviews and meta-analyses. The results indicated a gradual increase in the number of annual publications on acupuncture analgesia in clinical practice. Among countries and institutions, China (2,139) and Chengdu University of Traditional Chinese Medicine (258) ranked first. Liang FR (89 articles) was the most prolific author, while MacPherson H (604) was the most cited author. MEDICINE (455) was the most productive journal, and Pain (2,473/0.20) ranked first in both the frequency and centrality of cited journals. Notably, the most frequently cited reference was a systematic review of individual patient data on acupuncture carried out for chronic pain that was published by Vickers Andrew J in 2012 (156). Burst analysis identified frontier research areas for 2010-2020, encompassing network meta-analysis, case reports, dry needling, lumbar disc herniation, cancer, post-herpetic neuralgia, insomnia, and bibliometric analysis.

Conclusion

This study outlines current trends and potential future research hotspots in clinical acupuncture analgesia over the past decade. Findings emphasize the necessity for enhanced international collaboration to improve research output and translation.

Factors and Their Impact on Treatment Effect of Acupuncture in Different Outcomes: A Meta-Regression of Acupuncture Randomized Controlled Trials

BACKGROUND

The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results.

OBJECTIVE

To identify factors and their impact on the treatment effect of acupuncture in different outcomes.

METHODS

Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects.

RESULTS

The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01).

CONCLUSIONS

High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Acupuncture for post-stroke spasticity: An overview of systematic reviews

BACKGROUND

Post-stroke spasticity (PSS) is the most common complication of stroke. Acupuncture is widely used in clinical practice for the treatment of PSS, and is therefore considered a common complementary treatment. Several systematic reviews (SRs) and meta-analyses (MAs) have demonstrated the efficacy and safety of acupuncture in the treatment of PSS; however, the quality of evidence of these studies has not been adequately assessed.

OBJECTIVE

To evaluate and summarize the SRs/MAs and inform future research and clinical practice on the efficacy and safety of acupuncture for PSS.

DATA SOURCES AND EXTRACION

The following databases were searched from their dates of inception to March 26, 2023: PubMed, Embase, The Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Wanfang Database, SinoMed, and Chinese Science and Technology Periodical Database (VIP), and grey literature were manually searched. Two reviewers independently completed literature retrieval, screening, and data extraction.

REVIEW APPRAISAL

Systematic evaluation tools to Assess Systematic Reviews (AMSTAR) 2, Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA 2020 Checklist), and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system were used to systematically evaluate the methodological, reporting, and evidence quality of the SRs/MAs.

RESULTS

Overall, 226 papers were examined, and after careful consideration, 10 SRs/MAs were deemed eligible for inclusion. The AMSTAR 2 assessment revealed that one SR/MA had medium, one study had low, and the remaining eight studies had critically low methodological qualities. Additionally, four SRs/MAs completed more than 60 % of the PRISMA 2020 checklist. The GRADE system indicated that six outcomes were medium, 26 outcomes were low, and 24 outcomes were critically low.

CONCLUSION

Based on the evidence, acupuncture may be a promising complementary treatment to improve post-stroke spasticity and quality of life. Further high-quality RCTs are needed in future studies to support the broader application of acupuncture for the treatment of PSS.

Acupuncture therapy for Parkinson's disease: a case report demonstrating symptomatic improvement without medication

Background

Parkinson's disease (PD) often necessitates immediate medical intervention following diagnosis. In recent years, there has been a noticeable increase in clinical investigations assessing the efficacy of acupuncture in PD, with many studies reporting positive outcomes. Ethical guidelines commonly endorse pharmaceutical therapies for PD, leading ongoing research to combine acupuncture with standard drug-based treatments. At present, there is a conspicuous absence of dedicated clinical research exclusively examining the independent impact of acupuncture on PD treatment.

Case

In a clinical observation, we documented a case involving a 75-year-old male displaying progressive, characteristic PD symptoms, including evident limb tremors, rigidity, bradykinesia, fatigue, and additional non-motor symptoms. The patient received a confirmed diagnosis of PD. Due to the refusal of the patient to take medication, we exclusively administered acupuncture therapy. The outcomes indicated a noteworthy enhancement in the clinical symptoms of the patient solely through acupuncture intervention.

Conclusion

This case affirms that using acupuncture in isolation significantly improved both the motor and non-motor symptoms in the patient. Acupuncture could potentially serve as an alternative therapy for patients who decline or are intolerant to anti-Parkinson drugs. However, further studies are needed to assess its long-term efficacy. This case report obtained approval from the Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine (Ethics number: K-2023-127).

Comprehensive consideration of multiple determinants from evidence to recommendations in guidelines for most traditional Chinese medicine was suboptimal: a systematic review

BACKGROUND

The overall comprehensive consideration of the factors influencing the recommendations in the traditional Chinese medicine (TCM) guidelines remains poorly studied. This study systematically evaluate the factors influencing recommendations formation in the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) clinical practice guidelines (CPGs) and TCM CPGs.

METHODS

This was a methodological review in which we searched six databases and multiple related websites. The GRADE CPGs were identified as the guidelines developed by the GRADE Working Group or the two Co-Chairs. For the TCM CPGs, we randomly selected guidelines that were published by the TCM or integrative medicine academic societies from China mainland (published by the TCM or integrative medicine academic societies of China mainland). Two reviewers independently screened and extracted data. We included CPGs published in 2018-2022. We extracted information on the influencing factors of evidence to recommendation and conducted the analyses using descriptive statistics and calculated the proportion of relevant items by IBM SPSS Statistics and Microsoft Excel to compare the differences between the GRADE CPGs and the TCM CPGs.

RESULTS

Forty-five GRADE CPGs (including 912 recommendations) and 88 TCM CPGs (including 2452 recommendations) were included. TCM recommendations mainly considered the four key determinants of desirable anticipated effects, undesirable anticipated effects, balance between desirable and undesirable effects, certainty of evidence, with less than 20% of other dimensions. And TCM CPGs presented more strong recommendations (for or against) and inappropriate discordant recommendations than GRADE CPGs. GRADE CPGs were more comprehensive considered about the factors affecting the recommendations, and considered more than 70% of all factors in the evidence to recommendation.

CONCLUSIONS

The TCM CPGs lack a comprehensive consideration of multiple influencing determinants from evidence to recommendations. In the future, the correct application of the GRADE approaches should be emphasized.

Trends and hotspots related to traditional and modern approaches on acupuncture for stroke: A bibliometric and visualization analysis

BACKGROUND

Acupuncture role in stroke treatment and post-stroke rehabilitation has garnered significant attention. However, there is a noticeable gap in bibliometric studies on this topic. Additionally, the precision and comprehensive methodology of cluster analysis remain underexplored. This research sought to introduce an innovative cluster analysis technique (called follower-leading clustering algorithm, FLCA) to evaluate global publications and trends related to acupuncture for stroke in the recent decade.

METHODS

Publications pertaining to acupuncture for stroke from 2013 to 2022 were sourced from the Web of Science Core Collection. For the assessment of publication attributes-including contributing countries/regions (e.g., US states, provinces, and major cities in China) in comparison to others, institutions, departments, authors, journals, and keywords-we employed bibliometric visualization tools combined with the FLCA algorithm. The analysis findings, inclusive of present research status, prospective trends, and 3 influential articles, were presented through bibliometrics with visualizations.

RESULTS

We identified 1050 publications from 92 countries/regions. An initial gradual rise in publication numbers was observed until 2019, marking a pivotal juncture. Prominent contributors in research, based on criteria such as regions, institutions, departments, and authors, were Beijing (China), Beijing Univ Chinese Med (China), the Department of Rehabilitation Medicine, and Lidian Chen (Fujian). The journal "Evid.-based Complement Altern" emerged as the most productive. The FLCA algorithm was effectively employed for co-word and author collaboration analyses. Furthermore, we detail the prevailing research status, anticipated trends, and 3 standout articles via bibliometrics.

CONCLUSION

Acupuncture for stroke presents a vast research avenue. It is imperative for scholars from various global regions and institutions to transcend academic boundaries to foster dialogue and cooperation. For forthcoming bibliometric investigations, the application of the FLCA algorithm for cluster analysis is advocated.

Clinical Efficacy and Mechanism of Transcutaneous Neuromodulation on Functional Dyspepsia

BACKGROUND AND AIMS

Prokinetics and proton pump inhibitors are first-line drugs for functional dyspepsia (FD) patients. However, no available treatment is effective for most FD patients, and the pathogenesis is still unclear. The purpose of this study was to investigate the therapeutic effect of transcutaneous neuromodulation (TN) on FD and its potential mechanisms.

MATERIALS AND METHODS

Fifty-seven FD patients were enrolled in the study and randomly divided into 3 groups (TN Neiguan (PC6) group, TN Zusanli (ST36) group, and sham TN group) that received corresponding treatment respectively for 4 weeks. Then, all the patients enrolled received TN PC6 combined with ST36 treatment for another 4 weeks. Dyspepsia symptom questionnaire, Medical outcomes study item short form health survey (SF-36), Hospital Anxiety and Depression Scale were used to assess the severity of symptoms. Gastric accommodation, gastric emptying rate, and related parameters of electrogastrogram were used to assess the pathophysiological mechanism of FD. The possible gastrointestinal hormonal mechanism involved was assessed by detecting serum ghrelin, neuropeptide Y, and vasoactive intestinal peptide. The possible duodenal inflammation mechanism involved was assessed by detecting duodenal mucosa.

RESULTS

TN treatment reduced the dyspepsia symptom score ( P <0.05) and improved the quality of life. After TN treatment, the gastric accommodation ( P <0.01), the gastric emptying rate ( P <0.01), and the percentages of preprandial ( P <0.05) and postprandial ( P <0.05) gastric slow waves (GSW) were increased. The proportions of preprandial ( P <0.05) and postprandial ( P <0.05) gastric electrical rhythm disorder were reduced. The double acupoint combination therapy further enhanced the therapeutic effect of single acupoint. In addition, the levels of ghrelin ( P <0.001) and neuropeptide Y ( P <0.001) were significantly increased, the level of vasoactive intestinal peptide ( P <0.001) was significantly decreased, and the total number of mast cells ( P <0.001) in the duodenal bulb was significantly decreased after double acupoints combination therapy.

CONCLUSIONS

TN treatment significantly improves the dyspepsia symptoms of FD patients and their quality of life. TN treatment increases the percentage of normal GSW, reduces the proportion of gastric electrical rhythm disorder, and improves the gastric accommodation and gastric emptying rate. The therapeutic effect of TN may be caused by regulating gastrointestinal hormone secretion and alleviating local inflammatory responses in duodenum. In addition, the improvement of TN on GSW was closely related to the decrease of bradygastria.

"The History of Chinese Medicine Really Is Very Detailed Regarding Pandemics": A Qualitative Analysis of Evidence-Based Practice and the Use of Chinese Herbal Medicine by Licensed Acupuncturists During the COVID-19 Pandemic in the United States

Objective: The objective of this qualitative study was to understand how licensed acupuncturists determined treatment strategies for patients with symptoms likely related to COVID-19 using Chinese herbal medicine (CHM) and the impact of the pandemic upon their clinical practice. Methods: A qualitative instrument was developed with questions aligned with when participants started treating patients with symptoms likely related to COVID-19 and the availability of information related to the use of CHM for COVID-19. Interviews took place between March 8 and May 28, 2021, and were transcribed verbatim by a professional transcription service. Inductive theme analysis and ATLAS.ti Web software were used to determine themes. Results: Theme saturation was achieved after 14 interviews lasting 11-42 min. Treatment predominantly started before mid-March 2020. Four themes emerged (1) information sources; (2) diagnostic and treatment decision-making; (3) practitioner experience; (4) resources and supplies. Conclusion: Primary sources of information informing treatment strategies came from China through professional networks and were widely disseminated throughout the United States. Scientific studies evaluating the effectiveness of CHM for COVID-19 were generally not deemed useful for informing patient care because treatment had been initiated before they were published and because of limitations associated with the research and the ability to apply it to real world practice.

Ayurveda research: Emerging trends and mapping to sustainable development goals

Ayurveda is India's prominent traditional medical system. The World Health Organization has stated the need for more evidence and data from conventional medicine methods to inform policymakers, regulatory bodies, healthcare stakeholders, and the public about its safe, effective, and equitable use. This study aims to provide a comprehensive analysis of the emerging trends in Ayurveda research, mapping research to the UN Sustainable Development Goals (SDG) and examining the impact of COVID-19. Using bibliometric methods, the researchers analyzed a total of 11,773 publications between 1993 and 2022 to understand the temporal evolution of publications, open-access publications, patterns of author collaboration, top-performing countries, and co-citation networks. The keyword co-occurrence analysis identifies networks of concentrated studies on Ayurveda research themes relating to the four clusters, Alternative and Traditional Medicine, Bioactive Compounds and Biological Activities, Analytical Techniques and Herbal Standardization, and Herbal Medicines and Immunomodulation, reflecting the diverse research areas within Ayurveda. The last cluster included research related to the SARS-CoV-2 virus, suggesting research on herbal approaches to immune modulation in the context of COVID-19. The most prominent SDG among these research themes was Good Health and Well-being (SDG 3), emphasizing the potential of natural products and traditional medicine in promoting holistic health and combating antibiotic resistance.

Global research trends of sham acupuncture: A bibliometric analysis

OBJECTIVE

Sham acupuncture has been used as a control in acupuncture efficacy trials. However, questions have been raised about whether it is a physiologically inert placebo. We aimed to understand global research trends and provide guidance for future research by conducting a bibliometric analysis of sham acupuncture studies.

METHODS

Journal articles published to date related to sham acupuncture were retrieved from Web of Science on May 29, 2023. The publication year, country, keyword, author, and organization of the studies were analyzed using the available bibliometric information. Using VOSviewer software, the co-occurrence of keywords in sham acupuncture studies was visualized as a network map by cluster analysis and overlay analysis according to the publication year.

RESULTS

A total of 3428 studies were included in the analysis. Studies on sham acupuncture have been steadily increasing since 1991, with most of the studies conducted in China (1514 studies, 44.17%), followed by the United States (789 studies, 23.02%) and South Korea (277 studies, 8.08%). The keywords of sham acupuncture research were classified into four clusters: evidence synthesis, pain clinical research, mechanism research, and acupressure research. Keyword analysis according to the publication year showed that evidence synthesis on sham acupuncture was recently focused on psychiatric conditions including depression and insomnia through systematic reviews, and clinical and mechanism studies on sham acupuncture were mostly conducted relatively in the past.

CONCLUSION

This bibliometric analysis provides a comprehensive overview of the development and global trends of sham acupuncture research to date, suggesting directions for future research.

Perception, attitudes, knowledge of using complementary and alternative medicine for cancer patients among healthcare professionals: A mixed-methods systematic review

BACKGROUND

With the rapid increase in the prevalence of cancer worldwide, the utilization of complementary and alternative medicine (CAM) has increased among cancer patients. This review aimed to understand the perception, attitudes, and knowledge of healthcare professionals toward using CAM for cancer patients.

METHODS

A mixed-methods systematic review was undertaken in four databases. Inclusion criteria were primary studies reporting perception, attitudes, and knowledge of healthcare professionals for using CAM for cancer patients were eligible. A mixed-methods convergent synthesis was carried out, and the findings were subjected to a GRADE-CERQual assessment of confidence.

RESULTS

Forty-two studies were chosen. The majority of the studies were quantitative and had less than 100 participants. Most publications were from European countries, and oncology was the highest among the specialties. The review found the following themes: feasibility of having negative adverse effects, low expectations of using CAM among HCPs, potential positive effects of using CAM, specific CAM training may be helpful, no concrete regulations to promote CAM practice, and poor physician-patient communication.

CONCLUSIONS

Nurses had more positive views than other professions; oncologists were concerned regarding herb-drug interactions; integration of CAM into the healthcare system was favorable; HCPs felt the need to participate in specific CAM training; and HCPs agreed that CAM education should be provided more regularly. Future studies should explore the studies views of cancer patients and details of in-depth evidence of CAM in oncology settings.

Emotional freedom techniques for treating post traumatic stress disorder: an updated systematic review and meta-analysis

Introduction

Clinical Emotional Freedom Techniques (EFT) is a psychophysiological intervention that includes cognitive and somatic elements, utilizing techniques from both Cognitive Behavioral Therapy (CBT) and Prolonged Exposure therapy (PE). Because only a single meta-analysis existed examining EFT for PTSD, this systematic review and meta-analysis represents an update.

Method

Ten databases were searched for quantitative reviews and randomised clinical trials, and six met inclusion criteria.

Results

Study quality and effect size were evaluated and the results demonstrated that treatment with Clinical EFT, when compared to wait list, usual care, or no treatment controls, resulted in significant and large effect sizes, ranging from 1.38 to 2.51. When compared to active controls, effect sizes ranged from -0.15 to 0.79, producing treatment results similar to other evidence-based therapies.

Discussion

Limitations are presented and considerations for further research are proposed.

Numerical Modeling and Simulation of Non-Invasive Acupuncture Therapy Utilizing Near-Infrared Light-Emitting Diode

Acupuncture is one of the most extensively used complementary and alternative medicine therapies worldwide. In this study, we explore the use of near-infrared light-emitting diodes (LEDs) to provide acupuncture-like physical stimulus to the skin tissue, but in a completely non-invasive way. A computational modeling framework has been developed to investigate the light-tissue interaction within a three-dimensional multi-layer model of skin tissue. Finite element-based analysis has been conducted, to obtain the spatiotemporal temperature distribution within the skin tissue, by solving Pennes' bioheat transfer equation, coupled with the Beer-Lambert law. The irradiation profile of the LED has been experimentally characterized and imposed in the numerical model. The experimental validation of the developed model has been conducted through comparing the numerical model predictions with those obtained experimentally on the agar phantom. The effects of the LED power, treatment duration, LED distance from the skin surface, and usage of multiple LEDs on the temperature distribution attained within the skin tissue have been systematically investigated, highlighting the safe operating power of the selected LEDs. The presented information about the spatiotemporal temperature distribution, and critical factors affecting it, would assist in better optimizing the desired thermal dosage, thereby enabling a safe and effective LED-based photothermal therapy.

Qualitative and quantitative meta-analysis of acupuncture effects on the motor function of Parkinson's disease patients

Objective

To explore the association between acupuncture sessions and its effects on the motor function of Parkinson's Disease (PD).

Methods

Eight databases and two clinical trials registries were searched from inception to August 2022. Randomized controlled trials (RCTs) that compared acupuncture with sham acupuncture, or antiparkinsonian drugs, were included. After qualitative meta-analysis, a non-linear meta regression approach with restricted cubic spline was used to investigate the dose-response relationship between acupuncture sessions and their efficacy on the Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) score. Subgroup meta-analysis was performed of the included studies according to the weekly acupuncture frequency. And finally, the included studies containing the determination of intermediate efficacy were compared.

Results

Of the 268 citations screened, 16 studies (462 patients of PD) were included. The qualitative meta-analysis showed that the acupuncture group had better effect on UPDRS-III scores than the control group. And the quantitative meta-analysis suggested that acupuncture dose was correlated with the reduction of UPDRS-III score in PD patients with motor symptoms. In subgroup analysis, on the one hand, when the frequency of acupuncture was no more than 3 times a week, with the increase of acupuncture session, the changes of UPDRS-III score decreased and then increased (P = 0.000). On the other hand, when acupuncture for more than 3 times a week and the dose of acupuncture treatment was <60 times, the changes of UPDRS-III score increased with the increase of acupuncture dose, but the score stopped to decrease if the dose continued to increase (P = 0.020). The comparative analysis of two quantitative RCTs found that the score improvement was more significant at the higher weekly acupuncture frequency.

Interpretation

This study found that when treating PD patients with motor symptoms, acupuncture treatment may need to reach a certain dose to obtain better therapeutic effect and excessive acupuncture stimulation may cause the body to develop a certain tolerance. However, the above results still need to be verified by more high-quality clinical studies. The protocol was registered on PROSPERO International Prospective Register of Systematic Reviews (CRD42022351428).

The relationship of publication language, study population, risk of bias, and treatment effects in acupuncture related systematic reviews: a meta-epidemiologic study

BACKGROUND

There are debates in acupuncture related systematic reviews and meta-analyses on whether searching Chinese databases to get more Chinese-language studies may increase the risk of bias and overestimate the effect size, and whether the treatment effects of acupuncture differ between Chinese and non-Chinese populations.

METHODS

In this meta-epidemiological study, we searched the Cochrane library from its inception until December 2021, and identified systematic reviews and meta-analyses with acupuncture as one of the interventions. Paired reviewers independently screened the reviews and extracted the information. We repeated the meta-analysis of the selected outcomes to separately pool the results of Chinese- and non-Chinese-language acupuncture studies and presented the pooled estimates as odds ratios (OR) with 95% confidence interval (CI). We calculated the Ratio of ORs (ROR) by dividing the OR of the Chinese-language trials by the OR of the non-Chinese-language trials, and the ROR by dividing the OR of trials addressing Chinese population by the OR of trials addressing non-Chinese population. We explored whether the impact of a high risk of bias on the effect size differed between studies published in Chinese- and in non-Chinese-language, and whether the treatment effects of acupuncture differed between Chinese and non-Chinese population.

RESULTS

We identified 84 Cochrane acupuncture reviews involving 33 Cochrane groups, of which 31 reviews (37%) searched Chinese databases. Searching versus not searching Chinese databases significantly increased the contribution of Chinese-language literature both to the total number of included trials (54% vs. 15%) and the sample size (40% vs. 15%). When compared with non-Chinese-language trials, Chinese-language trials were associated with a larger effect size (pooled ROR 0.51, 95% CI 0.29 to 0.91). We also observed a higher risk of bias in Chinese-language trials in blinding of participants and personnel (97% vs. 51%) and blinding of outcome assessment (93% vs. 47%). The higher risk of bias was associated with a larger effect estimate in both Chinese-language (allocation concealment: high/unclear risk vs. low risk, ROR 0.43, 95% CI 0.21 to 0.87) and non-Chinese-language studies (blinding of participants and personnel: high/unclear risk vs. low risk, ROR 0.41, 95% CI 0.23 to 0.74). However, we found no evidence that the higher risk of bias would increase the effect size of acupuncture in Chinese-language studies more often than in non-Chinese-language studies (the confidence intervals of all ROR in the high-risk group included 1, Table 3). We further found acupuncture appeared to be more effective in Chinese than in non-Chinese population (Table 4).

CONCLUSIONS

The findings of this study suggest the higher risk of bias may lead to an overestimation of the treatment effects of acupuncture but would not increase the treatment effects in Chinese-language studies more often than in other language studies. The difference in treatment effects of acupuncture was probably associated with differences in population characteristics.

Research trends of acupuncture therapy for hypertension over the past two decades: a bibliometric analysis

Acupuncture has already been extensively utilized to treat high blood pressure (hypertension) in several nations. Nevertheless, the bibliometric research on the worldwide usage of acupuncture for hypertension is mostly unclear. As a result, our objective for the research aimed to investigate the present state as well as developments in the global usage of acupuncture on hypertension during the last 20 years using CiteSpace (5.8.R2). The Web of Science (WOS) database examined papers on acupuncture treatment of hypertension from 2002 to 2021. We examined the number of publications, cited journals, nations/regions, organizations, authors, cited authors, cited references, and keywords utilizing CiteSpace. The record of 296 documents was obtained between 2002 and 2021. The quantity and frequency of annual publications rose gradually. Regarding frequency and centrality of citations, Circulation and Clin Exp Hypertens (Clinical and Experimental Hypertension) scored top and second respectively. China had the most publications among countries/regions, as well as the five largest institutions were also in China. Cunzhi Liu was the most productive author, while P Li was the most referenced author. XF Zhao produced the first article inside the quantity of cited references classification. 'Electroacupuncture' had a significant frequency with centrality for the keywords, which suggested electroacupuncture is a popular treatment in this field. In the treatment of hypertension, electroacupuncture has a beneficial effect on reducing blood pressure. However, because of the many different applications of electroacupuncture frequencies in research, whether the electroacupuncture frequency is connected to the therapeutic impact should be given more significant consideration. The findings of this bibliometric analysis give an overview of the present state as well as developments of clinical studies on acupuncture for hypertensive patients during the last two decades, which could assist researchers in identifying hot subjects and exploring novel directions in further study within the field.

Approach to Assess Adequacy of Acupuncture in Randomized Controlled Trials: A Systematic Review

OBJECTIVE

To summarize and identify the available instruments/methods assessing the adequacy of acupuncture in randomized controlled trials (RCTs) for proposing a new improved instrument.

METHODS

A systematic literature search was carried out in 7 electronic databases from inception until 21st November 2022. Any study evaluating the adequacy or quality of acupuncture, specifying specific acupuncture treatment-related factors as criteria of subgroup analysis, or developing an instrument/tool to assess the adequacy or quality of acupuncture in an RCT was included. Basic information, characteristics and contents of acupuncture adequacy assessment were presented as frequencies and percentages.

RESULTS

Forty studies were included in this systematic review. Thirty-five studies (87.50%) were systematic reviews, none of which used formal methods to develop the assessment instruments/methods of acupuncture adequacy; of 5 methodological studies, only 1 study used a relatively formal method. Thirty-two studies (82.05%) assessed the components of acupuncture, while 7 (17.95%) assessed the overall quality of acupuncture. An independent assessment instrument/method was used to assess acupuncture adequacy in 29 studies (74.35%), whereas as one part of a methodological quality assessment scale in 10 (25.65%). Only 9 (23.00%) studies used the assessment results for subgroup analysis, sensitivity analysis or the criteria for inclusion in the meta-analysis.

CONCLUSION

Assessment contents for adequacy or quality of acupuncture in RCTs hadn't still reached consensus and no widely used assessment tools appeared. The methodology of available assessment instruments/scales is far from formal and rigorous. A new instrument/tool assessing adequacy of acupuncture should be developed using a formal method.

Specification of interventions and selection of controls in randomized controlled trials of acupuncture: a cross-sectional survey

OBJECTIVE

Specification of interventions and selection of controls are two methodological determinants for a successful acupuncture trial. However, current practice with respect to these two determinants is not fully understood. Thus, we conducted a cross-sectional survey to examine the specification of interventions and selection of controls among published randomized controlled trials (RCTs) of acupuncture.

STUDY DESIGN AND SETTING

We searched PubMed for acupuncture RCTs published in core clinical journals and complementary and alternative medicine (CAM) journals from January 2010 to December 2019 (10 years) and included RCTs that assessed treatment effects of acupuncture versus any type of control. We used network meta-analyses to explore whether there were differential treatment effects in patients with chronic pain when using sham acupuncture as a control versus using waiting list or no treatment.

RESULTS

Most of the 319 eligible RCTs specified well the style of acupuncture (86.8%), traditional acupuncture point locations (96.2%), type of needle stimulation (90.3%) and needle retention time (85.6%). However, other acupuncture details were less-frequently specified, including response sought (65.5%), needle manipulation (50.5%), number of needle insertions (21.9%), angle and direction of insertion (31.3%), patient posture (32.3%) and co-interventions (22.9%). Sham acupuncture (41.4%) was the most frequently used control, followed by waiting list or no treatment (32.9%). There was no differential treatment effect when using sham acupuncture versus waiting list/no treatment as a control (standardized mean difference = -0.15, 95% confidence interval: -0.91 to 0.62).

CONCLUSION

Over a decade of research practice, important gaps have remained in the specification of acupuncture interventions, including response sought, needle manipulation, and co-interventions. While sham acupuncture has been widely used, waiting list or no treatment may also be considered as an appropriate control.

Toward a 'green allopathy'? Naturopathic paradigm and practice in Ontario, Canada

Epistemic tensions have long been evident within naturopathy, a heterodox healthcare occupation licensed across much of North America. Naturopaths less inclined toward bioscientific explanatory and evidentiary norms have long used the trope of the 'green allopath' to critique the practices of their more biomedically- (i.e., 'allopathically') inclined colleagues. Using the 'green allopathy' narrative as a conceptual starting point, this work uses a qualitatively-driven, mixed methods design involving interviews (n = 17) and a census-style survey (n = 366) to characterize the paradigmatic and practice patterns of licensed naturopaths in Ontario, Canada between 2017 and 2019. At odds with many interviewees' accounts, survey results suggest that the occupation's overall epistemic character, aligned with the concept of holism, has not changed much over the last two decades. Nevertheless, findings suggest notable changes in Ontario naturopaths' clinical practice patterns over the same period, including: more frequent use of botanical medicines, nutritional supplements and acupuncture; less frequent use of physical medicine (e.g., massage, hydrotherapy); and, an overall reduction in homeopathic usage. Controlling for other factors, older naturopaths are more likely to rely often on non-biomedical diagnostic modes (p = 0.042), suggesting an emerging shift, in practice, toward a 'green allopathy'. Naturopaths' widespread ongoing engagement with therapeutic modalities whose epistemic premises diverge strongly from conventional biomedicine (e.g., homeopathy, East Asian medicine), appears mediated by the increasing body of related bioscientific evidence, and by gender and age (p-values <0.05). Gender and age also significantly predict naturopaths' alignment with more pharmaceutically-oriented care (p values < 0.05). Though naturopathy's 'green allopathization' appears underway, the demographic predominance of women within the profession may temper this trend in the years ahead.

A Bibliometric Analysis of COVID-19 Scientific Literature From the English-Speaking Caribbean

The COVID-19 pandemic has led to a global crisis and has affected the Caribbean islands, leading to significant health and socioeconomic consequences in this region. Efforts to mitigate the burden of this disease have led to an accelerated amount of research in the English-speaking Caribbean (ESC). This bibliometric analysis aimed to evaluate the COVID-19-related scientific literature from the ESC nations. A total of 175 articles were included and analyzed from an initial PubMed search (n = 638) for COVID-19-related scientific literature from the ESC nations published between January 1, 2020, and June 30, 2022. Microsoft Excel 2016 (Microsoft Corporation, Redmond, Washington) and the VOSviewer (version 1.6.18) were used to characterize countries, authorship, journals, affiliations, and keywords of the COVID-19-related articles. Trinidad and Tobago (38%), Jamaica (22%), Barbados (20%), and Grenada (15%) contributed to the greatest number of publications. The University of the West Indies (UWI) campuses in Trinidad and Tobago, Jamaica and Barbados, and St. George's University in Grenada were the most prolific institutions. Srikanth Umakanthan from the UWI was the most prolific author. Cureus, SN Comprehensive Clinical Medicine, and Frontiers in Public Health were the first three most productive journals; 59% of the 175 articles had either the first or last author affiliated with an institution in the ESC, and 19% of the articles were country-focused: Trinidad and Tobago (16/175), Jamaica (9/175), Barbados (5/175), and Antigua and Barbuda (2/175). Among the top themes of research, 27% were outbreak response and rearrangements, epidemiological studies (23%), clinical management (23%), and medical education (13%). Over the last two years, an interest stimulated by the pandemic has expanded the research in ESC countries. However, gaps in the knowledge exist, especially in the epidemiology of COVID-19 complications in the sub-populations of chronic non-communicable diseases, post-COVID syndrome, and the long-COVID syndrome in the region. Hence, there is enormous scope for more research across the region.

Bibliometric analysis: Research trends of acupuncture treatment to cognitive impairment in recent 15 years

Objectives

Acupuncture therapy has been used for cognitive impairment-related diseases, however, there are still few studies on the overall trend of acupuncture therapy on cognitive impairment based on bibliometric analysis. The purpose of this study was to explore the research trend of the impact of acupuncture on cognitive impairment in the past 15 years, analyze the research trends and hotspots, and provide new ideas and theoretical basis for future research directions.

Methods

From the Web of Science Core Collection (WoSCC), the relevant literature on the treatment of cognitive impairment with acupuncture from 2007 to 2022 was retrieved. Then, based on the CiteSpace and VOSviewer software of the Java platform, the cooperation between countries and institutions in this field, the co-citation of journals and documents, and the cooperation between authors and authors, etc. were analyzed. In addition, the co-occurrence and burst analysis of keywords are also carried out, and a visual knowledge map is drawn.

Results

As of August 08, 2022, a total of 394 records related to the treatment of cognitive impairment with acupuncture were identified. The analysis results show: The number and rate of annual publications have steadily increased, with some fluctuations from year to year. The countries that contribute the most to this field are China and the USA. Among them, Beijing University of Chinese Medicine and Capital Medical University are tied for first place in terms of the number of published papers. Tao Jing is the most prolific author and the number one cited author.

Conclusions

The number of publications on acupuncture for cognitive impairment is expected to increase rapidly in future research, suggesting a bright future for the field. Future research hotspots will focus on pain, injury, protocol, diagnosis, guidelines, etc. It is also necessary to strengthen cross-regional and cross-country cooperation among various academic groups.

Acupuncture for Post-Stroke Cognitive Impairment: An Overview of Systematic Reviews

Background

Post-stroke cognitive impairment (PSCI) is one of the most common complications after stroke. In recent years, as a complementary alternative therapy, many systematic reviews (SRs) and meta-analysis (MAs) have reported the efficacy and safety of acupuncture in improving cognitive function in patients with PSCI, but the quality of evidence is unknown and therefore needs to be evaluated comprehensively.

Aim

We aimed to evaluate the SRs of acupuncture for patients with PSCI, to summarize the evidence quality of SRs to provide scientific evidence.

Methods

We searched for relevant SRs and MAs in seven databases up to March 22, 2022. Two reviewers independently completed literature retrieval, screening, and data extraction. We used A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2) to evaluate the methodological quality; the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool to determine the strength of evidence; and the ROBIS tool to assess RoB.

Results

We identified 14 SRs. The methodological quality of all SRs was low (2/14) or very low (12/14). GRADE results showed 13 were moderate quality (26%), 5 were low quality (10%), and 32 were very-low quality (64%). RoB showed that one SR had a low risk and 13 had a high risk. Moderate quality results showed that combined acupuncture therapy was superior to western medicine or cognitive rehabilitation training in improving cognitive function, the total response rate, and the daily living ability of patients with PSCI.

Conclusion

Based on the evidence, acupuncture appears to be effective and safe in improving cognitive function for patients with PSCI, but the overall quality of SRs is not high. High-quality randomized controlled trials are needed to confirm the effectiveness and safety of acupuncture on the cognitive function of patients with PSCI.

Acupuncture as a post-stroke treatment option: A narrative review of clinical guideline recommendations

BACKGROUND

Acupuncture may be useful to treat the various clusters of symptoms occurring after a stroke. The use of evidence to underpin clinical practice and treatment guidelines (CPGs and TGs respectively) varies from country to country and may affect what recommendations are made by guideline developers.

PURPOSE

To examine the extent to which international clinical and treatment guidelines on post-stroke treatment mention the role of acupuncture and to identify what symptoms they recommend for its use.

METHOD

Scoping of national and international websites of CPGs and TGs r on the after care and rehabilitation of stroke patients provided by professional and government organisations was conducted. The presence/absence of recommendations and the underpinning evidence was appraised for the use of acupuncture for symptoms following stroke.

RESULTS

Of 84 CPGs and TGs on post stroke after-care identified from 27 countries between 2001 and 2021, 49 made statements about acupuncture. Positive recommendations on the use of acupuncture were identified for 15 symptom areas from 11 countries for: stroke rehabilitation, dysphagia, shoulder pain, motor recovery, walking, balance, spasticity, upper limb extremity impairment, post-stroke pain, central post stroke pain, cognitive disorder, depression, and sleep problems. Thirty-five CPGs (2001-2018) from 18 countries published over the same period were identified that made no mention of acupuncture and therefore no recommendations were made on its use.

CONCLUSIONS

Currently, evidence used by international guideline developers varies and this influences whether a positive or negative recommendation is made. Recommendations to use acupuncture should be based on the best available evidence which has been quality appraised.

Factors Associated with the Magnitude Of acUpuncture treatment effectS (FAMOUS): a meta-epidemiological study of acupuncture randomised controlled trials

OBJECTIVE

To identify factors and assess to what extent they impact the magnitude of the treatment effect of acupuncture therapies across therapeutic areas.

DATA SOURCE

Medline, Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc, between 2015 and 2019.

STUDY SELECTION

The inclusion criteria were trials with a total number of randomised patients larger than 100, at least one patient-important outcome and one of two sets of comparisons.

DATA ANALYSIS

The potential independent variables were identified by reviewing relevant literature and consulting with experts. We conducted meta-regression analyses with standardised mean difference (SMD) as effect estimate for the dependent variable. The analyses included univariable meta-regression and multivariable meta-regression using a three-level robust mixed model.

RESULTS

1304 effect estimates from 584 acupuncture randomised controlled trials (RCTs) were analysed. The multivariable analyses contained 15 independent variables . In the multivariable analysis, the following produced larger treatment effects of large magnitude (>0.4): quality of life (difference of adjusted SMDs 0.51, 95% CI 0.24 to 0.77), or pain (0.48, 95% CI 0.27 to 0.69), or function (0.41, 95% CI 0.21 to 0.61) vs major events. The following produced larger treatment effects of moderate magnitude (0.2-0.4): single-centred vs multicentred RCTs (0.38, 95% CI 0.10 to 0.66); penetration acupuncture vs non-penetration types of acupuncture (0.34, 95% CI 0.15 to 0.53); non-pain symptoms vs major events (0.32, 95% CI 0.12 to 0.52). The following produced larger treatment effects of small magnitude (<0.2): high vs low frequency treatment sessions (0.19, 95% CI 0.03 to 0.35); pain vs non-pain symptoms (0.16, 95% CI 0.04 to 0.27); unreported vs reported funding (0.12, 95% CI 0 to 0.25).

CONCLUSION

Patients, clinicians and policy-makers should consider penetrating over non-penetrating acupuncture and more frequent treatment sessions when feasible and acceptable. When designing future acupuncture RCTs, trialists should consider factors that impact acupuncture treatment effects.

A comprehensive search string informed by an operational definition of complementary, alternative, and integrative medicine for systematic bibliographic database search strategies

BACKGROUND

Determining which therapies fall under the umbrella of complementary, alternative, and/or integrative medicine (CAIM) is difficult for several reasons. An operational definition is dynamic, and changes depending on both historical time period and geographical location, with many countries integrating or considering their traditional system(s) of medicine as conventional care. We have previously reported the first operational definition of CAIM informed by a systematic search. In the present study, we have developed a comprehensive search string informed by an operational definition of CAIM for systematic bibliographic database search strategies.

METHODS

We developed a single search string for the most common bibliographic databases, including those searchable on the OVID platform (e.g., MEDLINE, EMBASE, PsycINFO, AMED), the EBSCO platform (e.g., ERIC, CINAHL), Scopus, and Web of Science, using the finalised operational definition of CAIM's 604 therapies. We searched the Therapeutic Research Center's "Natural Medicines" database for all 604 therapies, and each item's scientific name and/or synonym was included as a keyword or phrase in the search string.

RESULTS

This developed search string provides a standardised list of CAIM terms (i.e., keywords and phrases) that may be searched on bibliographic databases including those found on the OVID platform (e.g., MEDLINE, EMBASE, PsycINFO, AMED), the EBSCO platform (e.g., ERIC, CINAHL), Scopus, and Web of Science.

CONCLUSION

Researchers can select relevant terms for their CAIM study and insert the keywords/phrases into these databases to receive all accessible data. This search technique can simply be copied and pasted into the search bar of each database to identify research by keywords, which is the most inclusive, or by words in the article title, which is more selective. Given its versatility across multiple commonly used academic platforms/databases, it is expected that this search string will be of great value to those conducting research on CAIM topics involving systematic search strategies.

Skin Temperature of Acupoints in Health and Disease: A Systematic Review

Introduction: Despite substantial progress made in the field of acupuncture research, the existence and specificity of acupoints remain controversial. In recent years, the concept of acupoint sensitization has emerged as a theoretical framework for understanding acupoints as dynamic functional entities that are sensitized in pathological conditions. Based on this premise, some have claimed that specific acupoints are thermally distinct between healthy and clinical populations, but no systematic review has been conducted to synthesize and evaluate the quality of studies supporting such claims. In this review, we provide a summary and quality assessment of the existing literature addressing the question of whether changes in skin temperature at specific acupoints are indicative of pathological conditions. Methods: A systematic literature search was performed in PubMed, EMBASE, and AltHealthWatch (EBSCO Host), by combining variations of search terms relevant to acupoints and temperature. The search was limited to the English language, and publication dates ranged from database inception to December 2020. Two authors independently screened all resulting abstracts and subsequently read full-text articles for eligibility. Information on study design, sample, acupoints, parameters of skin temperature assessments, and main findings were extracted from included studies. Quality of the thermal sensing methodology was evaluated using a thermal assessment checklist, adapted from the Thermographic Imaging in Sports and Exercise Medicine (TISEM) consensus checklist, and a modified Newcastle-Ottawa Scale (NOS) for case-control studies. Results: The search strategy yielded a total of 1771 studies, of which 10 articles met the eligibility criteria. Eight studies compared skin temperature at acupoints in healthy versus clinical populations, and two studies assessed within-subject changes in temperature of acupoints in relation to changes in health status. There were seven clinical conditions examined in the included studies: chronic bronchial asthma, chronic hepatitis, hyperplasia of mammary glands, infertility, intracranial hypertension, obesity, and primary dysmenorrhea. There were numerous methodological quality issues related to skin temperature measurements. Eight studies with case-control designs reported significant differences between healthy and clinical populations in temperature at certain acupoints. Two studies with pre-post designs reported that changes in health-disease status could be associated with changes in temperature at specific acupoints. Conclusion: A review of the available literature suggests that certain acupoints may be thermally distinct between healthy and unhealthy states. However, given the methodological limitations and heterogeneity across included studies, no definitive conclusion could be drawn as to whether changes in skin temperature at specific acupoints are indicative of pathological conditions.

Acupuncture Analgesia in Patients With Traumatic Rib Fractures: A Randomized-Controlled Trial

Pain management for traumatic rib fracture is important to prevent complications and reduce associated comorbidities. This trial investigated the analgesic efficacy of acupuncture on traumatic rib fracture. Patients with traumatic rib fracture were randomly assigned to traditional acupuncture (TA), laser acupuncture (LA) or sham laser acupuncture (SLA) groups in a 1:1:1 ratio. The intervention was performed on days 1 to 3 after treatment allocation. The acupoints included bilateral LI4 (Hegu), SJ6 (Zhigou), ST36 (Zusanli) and GB34 (Yanglingquan). The primary outcome was Numeric Rating Scale (NRS) scores for pain after the intervention. Secondary outcomes included sustained maximal inspiration (SMI) lung volume, stress responses, the use of analgesics, and associated complications. Data were analyzed via one-way analysis of variance (ANOVA) with Scheffé's post hoc testing or chi-squared testing. Of the 120 study participants, 109 completed all interventions and measurements. The primary outcomes, which indicated average pain intensity levels and pain while deep breathing, were both significantly lower in the TA and LA groups than in the SLA group after 2 treatments. No between-group differences were observed in SMI lung volume, stress response, analgesics use or associated complications. These findings suggest that TA and LA are safe and effective analgesic modalities for pain management for traumatic rib fracture.

A search of just four key databases would identify most randomized controlled trials of acupuncture: a meta-epidemiological study

INTRODUCTION

Little research has been conducted to assess which specific databases should be searched when performing a systematic review (SR) on acupuncture. The current study aimed to identify key databases and the optimal database combination to retrieve randomized controlled trials (RCTs) on acupuncture for inclusion in SRs.

METHODS

A systematic search for SRs in the field of acupuncture was conducted in order to identify target databases and RCTs were extracted from the SRs that had searched all target databases. The proportions of SRs that had achieved 100%, 95% or 90% recall of RCTs and the total recall of RCTs in various combinations of target databases were calculated. Sensitivity analysis was performed on those SRs that included 10 or more RCTs.

RESULTS

CNKI, WanFang, VIP, PubMed, CENTRAL and Embase were regarded as target databases. A total of 4349 acupuncture RCTs were extracted from 286 SRs. Searching all six target databases retrieved 99.3% of all RCTs while 99.1% were recalled by searching the combination of CNKI, WanFang, PubMed and CENTRAL. There were no significant differences on total recall of RCTs (p=0.549) or in the proportion of SRs with 90% recall of RCTs (97.2% vs. 97.6%; p=0.794) between searching the above four and the full six target databases. Most results were similar in the sensitivity analysis.

CONCLUSION

The combined retrieval power of CNKI, WanFang, PubMed and CENTRAL was considered an efficient choice to retrieve acupuncture RCTs included in SRs. This article is protected by copyright. All rights reserved.

Evidence mapping and overview of systematic reviews of the effects of acupuncture therapies

OBJECTIVE

To provide a route map regarding systematic reviews (SRs) of acupuncture therapies that will meet two goals: (1) to identify areas in which more or better evidence is required and (2) to identify acupuncture applications that, although proven effective, remain underused in practice, and thus warrant more effective knowledge dissemination.

ELIGIBILITY CRITERIA

We included SRs that conducted meta-analyses (MAs) of randomised controlled trials (RCTs) for this overview.

INFORMATION SOURCES

We searched for SRs without language restrictions from January 2015 to November 2020 in four Chinese electronic databases and Epistemonikos database. And we also searched for newly published RCTs that were eligible for selected best SRs in PubMed, Medline, Cochrane Central Register of Controlled Trials, Embase and four Chinese electronic databases from its lasted search dates to November 2020.

SYNTHESIS OF RESULTS

We reanalysed the selected MAs if new primary studies were added. We used random-effect model to calculate the overall effect.

RESULTS

Our search identified 120 SRs published in the last 5 years addressing acupuncture therapies across 12 therapeutic areas and 77 diseases and conditions. The SRs included 205 outcomes and involved 138 995 participants from 1402 RCTs. We constructed 77 evidence matrices, including 120 SRs and their included RCTs in the Epistemonikos database. Seventy-seven SRs represented the effect estimate of acupuncture therapies. Finally, we system summarised the areas of possible underutilisation of acupuncture therapies (high or moderate certainty evidence of large or moderate effects), and the areas of warranting additional investigation of acupuncture therapies (low or very low certainty evidence of moderate or large effects).

CONCLUSION

The evidence maps and overview of SRs on acupuncture therapies identified both therapies with substantial benefits that may require more assertive evidence dissemination and promising acupuncture therapies that require further investigation.

Operational definition of complementary, alternative, and integrative medicine derived from a systematic search

BACKGROUND

Identifying what therapies constitute complementary, alternative, and/or integrative medicine (CAIM) is complex for a multitude of reasons. An operational definition is dynamic, and changes based on both historical time period and geographical location whereby many jurisdictions may integrate or consider their traditional system(s) of medicine as conventional care. To date, only one operational definition of "complementary and alternative medicine" has been proposed, by Cochrane researchers in 2011. This definition is not only over a decade old but also did not use systematic methods to compile the therapies. Furthermore, it did not capture the concept "integrative medicine", which is an increasingly popular aspect of the use of complementary therapies in practice. An updated operational definition reflective of CAIM is warranted given the rapidly increasing body of CAIM research literature published each year.

METHODS

Four peer-reviewed or otherwise quality-assessed information resource types were used to inform the development of the operational definition: peer-reviewed articles resulting from searches across seven academic databases (MEDLINE, EMBASE, AMED, PsycINFO, CINAHL, Scopus and Web of Science); the "aims and scope" webpages of peer-reviewed CAIM journals; CAIM entries found in online encyclopedias, and highly-ranked websites identified through searches of CAIM-related terms on HONcode. Screening of eligible resources, and data extraction of CAIM therapies across them, were each conducted independently and in duplicate. CAIM therapies across eligible sources were deduplicated.

RESULTS

A total of 101 eligible resources were identified: peer-reviewed articles (n = 19), journal "aims and scope" webpages (n = 22), encyclopedia entries (n = 11), and HONcode-searched websites (n = 49). Six hundred four unique CAIM terms were included in this operational definition.

CONCLUSIONS

This updated operational definition is the first to be informed by systematic methods, and could support the harmonization of CAIM-related research through the provision of a standard of classification, as well as support improved collaboration between different research groups.

Placebo Response Rates in Acupuncture Therapy Trials for Functional Dyspepsia: A Systematic Review and Meta-Analysis

BACKGROUND

Functional dyspepsia (FD) is a functional digestive disease with limited management selection. Previous studies revealed that acupuncture therapy is effective for FD. However, because sham controls were not implemented in most clinical trials following acupuncture therapy, it is difficult to differentiate overall treatment responses from placebo. This study aims to quantify placebo responses in clinical trials in which FD patients received sham manual acupuncture (MA) and sham electroacupuncture (EA).

MATERIALS AND METHODS

Randomized controlled trials of MA and EA for FD patients were searched in PubMed, Web of Science, Cochrane Library, and Embase databases, as well as 4 Chinese language databases from inception to January 2021. RevMan 5.20 software was used for pooled analysis of symptom scores and quality of life. The symptom scores were combined using standard mean difference (SMD) or weighted mean difference (WMD) with a 95% confidence interval (CI). The quality of included studies was tested using modified Jadad scale and Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) checklist. Egger's test, Begg's test, and sensitivity analyses were conducted using Stata 11.0 statistical software. The protocol of this study is registered in PROSPERO as CRD42021233858.

RESULTS

After screening, the current systematic review included 13 randomized controlled trials, of which 8 studies were used in the meta-analysis. Regarding subjective outcomes, the combined effect of sham MA on FD symptoms was [SMD=-0.42, 95% CI (-0.72, -0.12); P=0.005], whereas sham EA treatment was [SMD=-0.54, 95% CI (-0.81, -0.27); P<0.001]. The combined effect on FD quality of life of post-sham MA group was [SMD=-0.32, 95% CI (-0.52, -0.12); P=0.002]. With regard to objective outcomes, the combined effect of sham EA on dominant frequency was [WMD=-0.11, 95% CI (-0.30, -0.08); P=0.24], while the combined effect of sham EA on dominant power was [WMD=-3.35, 95% CI (-8.04, 1.35); P=0.16].

CONCLUSIONS

Sham MA and sham EA remarkably improve symptoms and quality of life scores of FD without influencing objective outcomes, highlighting the significance of sham controls in acupuncture therapy clinical trials.

The changing clinical landscape in acupuncture for women's health: a cross-sectional online survey in New Zealand and Australia

Background

Acupuncture is a popular treatment for women’s health. Several trials and meta-analysis have been published in recent years on key women’s health conditions but it is unclear if this has led to any changes in clinical practice or referrals from other health professionals. The aim of this survey was to explore if, how, and why, aspects of acupuncture practice have changed since our survey in 2013.

Method

An online cross-sectional survey of registered acupuncturists and Chinese Medicine practitioners in Australia and New Zealand. Questions covered the practitioner demographics and training, women’s health conditions commonly treated, modalities used, sources of information and continuing education (CE) (e.g. webinars), changes in clinical practice, and referral networks.

Results

One hundred and seventy registered practitioners responded to this survey, with 93% reporting treating women’s health in the last 12 months. The majority of respondents were from Australia (60%), held a bachelors level qualification (60%), and used a traditional Chinese medicine framework (86%). Most practitioners incorporated other modalities in addition to acupuncture. Most practitioners’ referral networks were predominantly based on word of mouth for menstrual, fertility and pregnancy related conditions, with referrals from medical practitioners being much less common. More than half (57%) reported having changed their women’s health practice in the past 12 months; just over a quarter of those who changed treatment (27%) reported it was due to research findings. The most commonly used sources of information/CE used to inform treatment were webinars and conferences, while peer-reviewed journal articles were the least commonly used source.

Conclusion

Acupuncture practitioners in Australia and New Zealand commonly treat women’s health conditions, but this is usually the result of women seeking them out, rather than being referred from a medical practitioner. The majority of practitioners did report changing their women’s health practice, but peer reviewed academic articles alone are not an ideal medium to convey this information since practitioners favour knowledge obtained from webinars and conferences. Academics and other clinician researchers should consider alternative means of disseminating knowledge beyond traditional academic publications and conferences, special interest groups may assist in this and also help improve research literacy.
