Effect of Needling at Selected Acupuncture Points (GB39, BL17, LR13) on Hemoglobin Levels in Anemia: a Randomized Placebo Controlled Study

Iron deficiency anemia (IDA) is an important public health issue in India. This study was performed to determine the impact of acupuncture at the GB39, BL17, and LR13 points on hemoglobin levels, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and red cell distribution width (RDW) in people with IDA. One hundred women with IDA were randomly allocated to the acupuncture group (AG) or placebo control group (PCG). For 30 minutes per day, daily for 2 weeks, the AG received acupuncture at GB39, BL17, and LR13, while the PCG received needling at non-acupuncture points. Outcomes were assessed before and after the intervention. We found a significant increase (p < 0.001) in hemoglobin level (AG 10.39-11.38 g/dl, effect size 0.785; PCG 10.58-10.40 g/dl, effect size 0.191), MCH (AG 25.69-27.50 fl, effect size 0.418; PCG 27.43-27.23 fl, effect size 0.058), and RDW (AG 15.12-16.41 fl, effect size 0.626; PCG 14.91-14.94 fl, effect size 0.017) in the AG compared to the PCG. Results suggest that needling at the GB39, BL17, and LR13 acupuncture points is more effective in treating people with IDA than needling at non-acupuncture points.

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.

Effectiveness of low-level laser therapy in reducing pain perception of children during dental local anesthetic administration using laser acupuncture pen on the LI4 point: a randomized clinical trial

PURPOSE

Laser acupuncture, a non-invasive variant of acupuncture, has been proven effective in the medical and dental fields. Hence, the present study aims to determine the effect of low-level laser therapy on the LI4 point, using a laser acupuncture pen, in reducing children's pain during local anesthetic (LA) administration.

METHODS

Children in the age range of 8-12 years, in need of LA administration, were randomly assigned to two groups: Group I: laser acupuncture, Group II: control. For all the children, baseline simplified Modified Child Dental Anxiety Scale-Faces version (MCDAS_(f)) was recorded, followed by laser acupuncture or standard care. Following the conventional protocol, LA was administered. The procedural pain was assessed using the Faces, Legs, Activity, Cry and Consolability scale (FLACC) and Faces Pain Scale-Revised (FPS-R). All the variations in pulse rate were recorded from baseline to the completion of LA administration. After the procedure, simplified MCDAS_(f) was recorded one more time. The data were tabulated and analyzed statistically.

RESULTS

A significant reduction in anxiety after LA administration, as observed in MCDAS_(f) score, was noticed only in the laser acupuncture group. The pain scores, as reported in FPS-R, were low in children randomized to the laser group compared to the control. The FLACC pain scores also showed low values in the experimental group.

CONCLUSION

Based on the study findings, within the limitations, low-level laser therapy using a laser acupuncture pen can reduce the pain perception of children undergoing LA administration and alleviate dental anxiety.

A Systematic Review of Systematic Reviews and a Pooled Meta-Analysis on Complementary and Integrative Medicine for Improving Cancer-Related Fatigue

PURPOSE

Evidence supporting complementary and integrative medicine (CIM) for improving cancer-related fatigue (CRF) is still fragmented. This study therefore critically appraised all the systematic reviews (SRs) regarding the effectiveness of CIM in mitigating CRF in adults.

METHODS

A systematic review of SRs and a meta-analysis were conducted in 4 databases. The effect sizes of the included SRs were quantitatively pooled (standardized mean difference [SMD]; 95% CI) using a random-effects model. Heterogeneity was tested by using χ² (Q) tests and I² statistics.

FINDINGS

Twenty-two SRs met the inclusion criteria, and results from 20 SRs underwent meta-analysis. The pooled significant estimate of fatigue reduction was as follows: SMD, -0.50; 95% CI, -0.67 to -0.32; P < 0.001. The subgroup analysis based on the type of CIM intervention revealed that the approach showing higher effects in reducing fatigue thus far is acupuncture: SMD, -0.99; 95% CI = -1.37 to -0.62, P < 0.001; I² = 84%. CIM therapies showed a significant reduction of fatigue in patients with breast cancer: SMD, -0.46; 95% CI, -0.69 to -0.23; P < 0.001; I² = 82%.

IMPLICATIONS

CIM interventions showed effectiveness in reducing CRF. Subgroup analysis suggested some potential influencing, such as tumor type and specific CIM therapy factors, that require in-depth assessment in future research. Study protocol registration: PROSPERO CRD42020194254.

Critical evaluation of reporting quality of network meta-analyses assessing the effectiveness of acupuncture

BACKGROUND

and purpose: Network meta-analyses (NMAs) comparing the effectiveness of multiple acupuncture have been published but the key concepts underlying NMAs have not been properly reported. This critical evaluation aims to assess the completeness of reporting for NMAs of acupuncture to enhance the validity of findings.

MATERIALS AND METHODS

Five databases were searched. The characteristics and reporting quality based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses Extension Statement for reporting of NMA (PRISMA-NMA) were evaluated. NMAs were categorized into two groups according to the publication date, reporting guideline, and intervention. The group differences and correlation coefficients were calculated.

RESULTS

Forty-two NMAs of acupuncture were evaluated. The reporting quality for new items in the key concepts of NMAs was low (median 70.0 % (interquartile range 60.0-80.0)). While the issue of consistency was well reported, the assumption of transitivity and network geometry showed poor reporting. Seventeen studies that followed the PRISMA-NMA guideline showed a higher reporting rate for essential concepts of NMA. The recency of publication did not guarantee clear reporting.

CONCLUSION

The reporting quality of NMAs of acupuncture was low. The researchers should follow the guidelines on the reporting of NMAs.

Clinical Events Associated with Acupuncture Intervention for the Treatment of Chronic Inflammation Associated Disorders

Acupuncture is a key component of Chinese medicine. It describes a series of procedures involving the stimulation of skin through penetration of fine, single-use, sterile needles that result in the release of neurotransmitters. Although its use is on the growing trend, considerable controversy surrounds its value as a therapy. Standard randomized controlled trials that adhere to the accepted criteria should be conducted in the future to ensure the effectiveness of acupuncture. This article summarizes the current evidence regarding the use of acupuncture. It includes a description of the history, mode of operation, treatment of a variety of chronic disorders related to inflammation, and future directions for acupuncture use. Published clinical trials support the view that acupuncture is a possible candidate for the treatment of several chronic inflammation-related disorders.

What intrinsic factors influence responsiveness to acupuncture in pain?: a review of pre-clinical studies that used responder analysis

BACKGROUND

Not many studies have investigated individual sensitivity to acupuncture. To explore the intrinsic factors related to individual responses to acupuncture, we reviewed published pre-clinical studies using responder analysis on pain.

METHODS

We searched the PubMed and EMBASE databases to June 2015. We included pre-clinical reports describing responders and non-responders to anti-nociceptive and analgesic effects of acupuncture in animal study. We identified the potential intrinsic factors which might be related with the response to acupuncture.

RESULTS

Totally, 216 potentially relevant articles were retrieved and 14 studies met our inclusion criteria. Rat (n = 1348) and rabbit (n = 56) were used, and only electroacupuncture (EA) was applied as an intervention. Results showed that high levels of cholecystokinin-8 and receptors were associated with poor responsiveness to EA. Endogenous opioids including β-endorphin and met-enkephalin, descending inhibitory norepinephrine and serotonin system, and hypothalamic 5'-AMP-activated protein kinase seemed to be associated with high-level responses. Spinal levels of neurotransmitters and pro-inflammatory cytokines were also differentially expressed depending on the EA sensitiveness. In the central nervous system, hypothalamus, periaqueductal grey, pituitary gland, and spinal cord were suggested to be involved in the EA responsiveness. Identified individual variations did not seem to be accidental, as the responsiveness to EA was replicated over time. However, methodological issues such as reproducibility, cut-off criteria, and clinical relevance need to be further elaborated.

CONCLUSION

Our study suggests that the identification of the biological factors differentiating responders from non-responders is necessary and it may aid in understanding how acupuncture modulates pain.

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

OBJECTIVE

Acupuncture has become popular and widely practiced in many countries around the world. Despite the large amount of acupuncture-related literature that has been published, broader trends in the prevalence and scope of acupuncture research remain underexplored. The current study quantitatively analyzes trends in acupuncture research publications in the past 20 years.

METHODS

A bibliometric approach was used to search PubMed for all acupuncture-related research articles including clinical and animal studies. Inclusion criteria were articles published between 1995 and 2014 with sufficient information for bibliometric analyses. Rates and patterns of acupuncture publication within the 20 year observational period were estimated, and compared with broader publication rates in biomedicine. Identified eligible publications were further analyzed with respect to study type/design, clinical condition addressed, country of origin, and journal impact factor.

RESULTS

A total of 13,320 acupuncture-related publications were identified using our search strategy and eligibility criteria. Regression analyses indicated an exponential growth in publications over the past two decades, with a mean annual growth rate of 10.7%. This compares to a mean annual growth rate of 4.5% in biomedicine. A striking trend was an observed increase in the proportion of randomized clinical trials (RCTs), from 7.4% in 1995 to 20.3% in 2014, exceeding the 4.5% proportional growth of RCTs in biomedicine. Over the 20 year period, pain was consistently the most common focus of acupuncture research (37.9% of publications). Other top rankings with respect to medical focus were arthritis, neoplasms/cancer, pregnancy or labor, mood disorders, stroke, nausea/vomiting, sleep, and paralysis/palsy. Acupuncture research was conducted in 60 countries, with the top 3 contributors being China (47.4%), United States (17.5%), and United Kingdom (8.2%). Retrieved articles were published mostly in complementary and alternative medicine (CAM) journals with impact factors ranging between 0.7 and 2.8 in the top 20 journals, followed by journals specializing in neuroscience, pain, anesthesia/analgesia, internal medicine and comprehensive fields.

CONCLUSION

Acupuncture research has grown markedly in the past two decades, with a 2-fold higher growth rate than for biomedical research overall. Both the increases in the proportion of RCTs and the impact factor of journals support that the quality of published research has improved. While pain was a consistently dominant research focus, other topics gained more attention during this time period. These findings provide a context for analyzing strengths and gaps in the current state of acupuncture research, and for informing a comprehensive strategy for further advancing the field.
