OBJECTIVES: To observe the clinical effect and safety of auricular point sticking combined with periocular needle-embedding therapy for pseudomyopia and prevention of true myopia. METHODS: A total of 269 children with pseudomyopia were randomized into an observation group (134 cases, 2 cases dropped out) and a control group (135 cases, 5 cases dropped out). In the control group, the healthy education was provided. In the observation group, besides the intervention as the control group, the auricular point sticking was delivered at gan (CO12), pi (CO13), xin (CO15) and yan (LO5) on one ear in each treatment, combined with periocular needle-embedding technique at bilateral Cuanzhu (BL 2), Yuyao (EX-HN 4) and Sibai (ST 2). There were 2 weeks of interval after 4 weeks of treatment. One course of treatment was composed of 6 weeks and 2 courses were required. Separately, before treatment, after 6 and 12 weeks of treatment, and after 12 weeks (the 1st follow-up visit) and 24 weeks (the 2nd follow-up visit) of treatment completion, the spherical equivalent (SE), SE progression, axial length (AL) progression, accommodative amplitude (AMP), the score of the TCM symptom and the general symptom were observed in the two groups. The safety and compliance were evaluated in the two groups. RESULTS: After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, SE increased when compared with that before treatment in the two groups (P<0.05), and AMP was larger than that before treatment in the observation group (P<0.05). After 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of SE was slower in the observation group compared with that in the control group (P<0.01, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the progression of AL in the observation group was lower than that of the control group (P<0.05, P<0.01, P<0.001); and in the 1st and 2nd follow-up visits, AMP of the observation group was larger when compared with that in the control group (P<0.05, P<0.001). After 6 and 12 weeks of treatment, and in the 1st and 2nd follow-up visits, the total scores of TCM symptom and general symptom were reduced in comparison with those before treatment in the observation group (P<0.05); after 6 and 12 weeks of treatment, the total scores of TCM symptom and general symptom were lower than those before treatment in the control group (P<0.05). In the 1st and 2nd follow-up visits, the difference of the total score of TCM symptom and general symptom in the observation group was larger than that of the control group (P<0.05). In the observation group, compared with the control group, the scores for pale/dark complexion in the 1st and 2nd follow-up visits and that for lassitude in the 2nd follow-up visit were lower (P<0.05), the score for poor concentration after 12 weeks of treatment and that for poor sleep and memory in the 2nd follow-up visit were lower (P<0.05). There were no adverse reactions in the two groups. The compliance was 98.5% in the observation group and was 96.3% in the control group, without statistical difference (P>0.05). CONCLUSIONS: On the basis of health education, auricular point sticking combined with periocular needle-embedding therapy can effectively prevent from true myopia, control the increase of SE, delay the growth of AL and improve AMP in children with pseudomyopia. This compound therapeutic regimen can relieve the general symptom and comprehensively prevent from myopia through multiple approaches, with high safety and satisfactory compliance.

Possible mechanisms of auricular acupoint stimulation in the treatment of migraine by activating auricular vagus nerve. / 从耳迷走神经探讨耳穴治疗偏头痛的可能机制.

Under the guidance of traditional Chinese medicine theory, the clinical research of auricular acupoint stimulation in the treatment of migraine has gained a lot, and the curative efficacy is definite, but its mechanism remains unclear. In the present paper, we discussed the efficacy of auricular acupoint stimulation including "transcutaneous auricular vagus nerve stimulation" (taVNS) in the treatment of migraine in recent years. Through bibliometric analysis, we screened out top 10 auricular acupoints (Shenmenï¼»TF4ï¼½, Pizhixiaï¼»AT4ï¼½, Jiaoganï¼»AH6aï¼½, Ganï¼»CO12ï¼½, Yidanï¼»CO11ï¼½, Neifenmiï¼»CO18ï¼½, Shenï¼»CO10ï¼½, Nieï¼»AT2ï¼½, Zhenï¼»AT3ï¼½ and Eï¼»AT1ï¼½) which were the most frequently used for migraine. Majority of these auricular acupoints just distributed in the region innervated by auricular vagus nerve. Thus, we thought that the analgesic effect of needling these auricular acupoints for migraine was produced by triggering the auricular vagus nerve, and concluded that the central mechanism underlying induction of analgesic effect by activating auricular vagus nerve may be achieved by activating the descending pain regulation pathway of the locus coeruleus nucleus and dorsal raphe nucleus. In addition, taVNS-induced 1) regulation of the activities of brain's default network and pain matrix, 2) activation of the cortical descending pain regulation pathway, and 3) inhibition of the neuroinflammatory response may also contribute to its ameliorating effect of migraine. This paper may provide ideas for the future research on the mechanism of auricular acupoint treatment of migraine.

Bibliometric analysis of auriculotherapy research trends over the past 20 years.

OBJECTIVES: Auriculotherapy has long been used to treat various diseases. We analyzed and visualized auriculotherapy's geographical distribution, key contributors, and thematic trends over the past 20 years to provide current trends in auriculotherapy field and to offer recommendations for future research directions. DESIGN/SETTING: We searched for relevant studies in the Web of Science between January 10, 2003, and December 31, 2022. A bibliometric analysis was performed using VOSviewer for annual publications, journals, countries, institutions, authors, and keywords. RESULTS: A total of 800 studies were included in the analysis, and the number of studies steadily increased over the 20 examined years. In 2018, there was a noteworthy rise in publications, nearly twice as many as the preceding year. Integrative & complementary medicine was the most researched area, with most articles published in Evidence-Based Complementary and Alternative Medicine. China was the country with the most published research, and the most active organization was Guangzhou University of Chinese Medicine in China, followed by Kyung Hee University in South Korea. The most prolific author was Yeh Mei-ling, who reported the effects of auriculotherapy on dysmenorrhea and smoking cessation. Keyword analysis revealed four clusters: pain, mental health, obesity, and smoking cessation. CONCLUSION: Auriculotherapy research primarily focused on clinical studies related to pain, obesity, smoking cessation, and depression. Future research should place greater emphasis on verifying the mechanisms of auriculotherapy for specific ailments and may require efforts to enhance the robustness of clinical trials. Through visual analysis, our study may serve as a foundational resource, offering valuable insights into the trajectory of auriculotherapy research.

Auricular Acupressure Improve Constipation of Patients With Schizophrenia: A Pilot Randomized Controlled Study.

Background. Constipation is a common distressing problem in patients with schizophrenia that can cause complications and impair quality of life. Objective. The objective of this study was to investigate the efficacy of applying auricular acupressure (AA) treatment in improving constipation in patients with schizophrenia. Methods. A crossover randomized controlled trial design was performed from April 2022 to December 2023 at four psychiatric rehabilitation care centers. A total of 23 patients with schizophrenia received an AA intervention or usual care according to the designated treatment sequences. Measurements comprised subjective assessment of constipation by the Patient Assessment of Constipation-Symptoms (PAC-SYM) questionnaire, an objective assessment of the stool pattern rated by a Bristol stool form scale, and heart rate variability. A generalized estimating equation model was used for data analyses. Results. After completing an 8-week AA intervention stimulating the Shenmen, San Jiao, Large intestine and Rectum, the AA group exhibited lower scores in the PAC-SYM total score (difference = -12.66, ,0.001), and the subscales: abdominal (difference = -3.36, p < .001), rectal (difference = -3.51, p < .001), and stool (difference = -5.79, p < .001), compared to those receiving usual care. The cases of constipation indicated by type 1 and type 2 of the BSF scale significantly decreased after the 8-week AA intervention. Moreover, the AA group displayed more parasympathetic dominance compared to the usual care group, with a low frequency to high frequency ratio of -1.15. Conclusion. AA is an effective non-pharmacological method for improving subjective constipation symptoms and objective stool pattern in patients with schizophrenia.

Auricular acupressure combined with Tongtian oral liquid for acute attacks of migraine without aura: a single-center, retrospective study.

OBJECTIVE: To observe the effect of auricular acupressure combined with Tongtian Oral Liquid for immediate pain relief in patients with acute migraine without aura, and to analyze the risk factors that affect the number of acute attacks of migraine without aura. METHODS: This retrospective study analyzed data of 180 patients diagnosed with acute migraine without aura who were admitted to Affiliated Hospital of Nanjing University of Chinese Medicine (Jiangsu Province Hospital of Chinese Medicine). The patients were divided into an intervention group 1 (n=60), an intervention group 2 (n=60), and a control group (n=60) according to different treatment methods. The intervention group 1 received auricular acupressure + Tongtian oral liquid, the intervention group 2 received Jing point bloodletting + Tongtian oral liquid, and the control group received ibuprofen + flunarizine. Before treatment, 60 minutes and 120 minutes after treatment, the visual analogue scale (VAS) and the short-form McGill pain questionnaire (SF-MPQ) were used to score the pain in the three groups to evaluate the efficacy of immediate analgesia. Symptoms including fatigue, drowsiness, nausea, and vomiting after 2 hours of treatment were observed. The amount of ibuprofen used within 24 hours was calculated. The drug treatment was continued for one month. The frequency of migraine attacks was compared among the three groups. The relevant factors affecting the number of migraine attacks were analyzed. RESULTS: The VAS and SF-MPQ scores of the three groups were all decreased 120 minutes after treatment as compared with those before treatment (P<0.01). The decline rate in the intervention group 1 > that in intervention group 2 > that in control group (P<0.01). The immediate analgesic efficiency at 60 minutes, intervention group 1 > intervention group 2 > control group (100% vs. 76.67% vs. 56.67%, P<0.001). After 2 hours of treatment, more cases of fatigue and lethargy occurred in the control group (P<0.05). There was no significant difference in nausea and vomiting among the three groups (P>0.05). The 24-hour ibuprofen dosage and headache recurrence ratio, control group > intervention group 2 > intervention group 1 (P<0.05). The number of headache attacks within 30 days was significantly higher in the control group than in the intervention groups (P=0.012). There was no significant statistical difference between the two intervention groups (P=0.568). Regression analysis found that age (OR=1.036, 1.006-1.068), body mass index (OR=1.101, 1.008-1.201), hypertension (OR=2.879, 1.187-6.986), chronic gastritis (OR=2.839, 1.213-6.647), children with educational problems (OR=0.333, 0.164-0.676), and residual fatigue symptoms (OR=4.539, 1.828-11.271) affected the number of headache attacks within the one month of treatment. CONCLUSIONS: Auricular acupressure combined with Tongtian Oral Liquid can relieve the acute pain of migraine without aura and reduce the number of pain episodes. The curative effect of this combination is better than that of western medicine alone.

Transcutaneous auricular vagus nerve stimulation for post-stroke depression: A double-blind, randomized, placebo-controlled trial.

BACKGROUND: It is a well-established fact that post-stroke depression (PSD) is a prevalent condition that affects a significant proportion of individuals who have suffered a stroke. Hence, our research endeavors to explore the safety, efficacy and the potential molecular mechanism of transcutaneous auricular vagus nerve stimulation (ta-VNS) for the treatment of depression in PSD patients by conducting a double-blind, sham-controlled, randomized trial. METHODS: Patients who had experienced strokes and exhibited depressive symptoms, with a Hamilton Depression Scale (HAMD-17) score of ≥8 and met the DSM-IV criteria, were diagnosed with PSD. A volunteer sample of participants (N = 80) were randomly divided into either the ta-VNS group (which received ta-VNS in addition to conventional treatment) or the control group (which received conventional treatment only), in a 1:1 ratio. The effectiveness of the interventions was evaluated using the 17-item Hamilton Rating Scale for Depression (HAMD-17), Zung Self-Rating Depression Scale (SDS), and Barthel Index (BI) scores. Furthermore, Plasma BDNF, CREB1, and 5-HT levels were measured before and after treatment. RESULTS: The concomitant application of ta-VNS demonstrated a remarkable reduction in HAMD-17 and SDS scores, leading to noteworthy enhancements in patients' daily functioning, as evidenced by improved activities of daily living, at all assessed time points, in contrast to the control group (p < 0.0001). Notably, the ta-VNS group exhibited superior effects in modulating the measured neurotrophic biomarkers when compared to the control group (p < 0.05). CONCLUSIONS: The synergistic approach of combining ta-VNS with conventional treatment has demonstrated remarkable efficacy and tolerability in managing depression following a stroke.

Effectiveness and safety of auricular acupuncture on adjuvant analgesia in patients with total knee arthroplasty: a randomized sham-controlled trial.

Objective: This study aimed to evaluate the effectiveness and safety of auricular acupuncture (AA) on postoperative analgesia, the degree of postoperative nausea, and the effect of inflammation after total knee arthroplasty (TKA). Methods: This was a single-center, placebo-controlled, randomized clinical trial. In total, 96 patients were randomly divided into an AA group with an indwelling intradermal needle (n = 48) and a sham auricular acupuncture (SAA) group with a non-penetrating placebo needle (n = 48). Intra-spinal anesthesia was adopted in both groups during surgery, and an epidural analgesic pump was implanted after surgery for 48 h. The primary outcome was the post-surgery visual analog score (VAS) of resting and movement states (at 6, 12 h and 1, 2, 3, 5, and 7 days). The secondary outcomes included additional doses of analgesic injection during the treatment, C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), and white blood cell (WBC) count on the 1st, 3rd, and 7th day after the operation, nausea on the 1st, 2nd, and 3rd day after the operation, the Hospital for Special Surgery Knee Score (HSS) on the 2nd and 12th week after the operation, and adverse events. Results: The VAS in the AA group at 6 h, 12 h, 2, 3, and 5 days after surgery were lower than those of the SAA group (p < 0.05). Among the secondary outcomes, the total dose of additional analgesic injection after surgery in the AA group was lower than that in the SAA group (p < 0.05). The serum CRP on the 1st day after operation in the AA group was lower than that in the SAA group (p < 0.05). The degree of nausea on 2nd day after surgery in the AA group was lower than that in the SAA group (p < 0.05). There was no significant difference in other outcomes (p > 0.05). Conclusion: In this study, AA was shown to be an effective and safe complementary and alternative therapy for pain relief after TKA, which was able to reduce the total postoperative dose of additional painkillers, decrease serum CRP 1 day after surgery, and improve the degree of postoperative nausea.

A scoping review of mechanisms of auricular acupuncture for treatment of pain.

OBJECTIVES: Auricular acupuncture (AA) is becoming increasingly common in primary care clinics, emergency departments and peri-operatively for pain relief. Over the last decade, since the last comprehensive reviews were published, the literature has expanded. In this scoping review, we seek to document the efficacy of AA in treating both acute and chronic pain, describe the mechanism of action of AA in treating pain, and discuss how AA has been integrated into Western medicine to date. METHODS: The authors performed a MEDLINE search inclusive of articles from 1966 to June 2023 including articles written in English identifying literature. We included human studies when more than 3 patients were included. Three hundred and fourteen unique articles were identified and 152 were selected by title screen. After abstract review, 117 were chosen for full-text review. Following full-text review, 33 articles were excluded and 21 added from references, totaling 105 articles included in our scoping review. RESULTS: AA reduces pain severity in patients with both acute and chronic pain. The best studies in the acute settings have occurred in the peri-operative setting where sham AA is employed, multiple sessions of AA are given, and medication dosing is carefully monitored. In these cases, AA reduced pain and post-operative medications. In patients with chronic pain, multiple sessions of AA resulted not only in pain relief but also in improvements in function and disability. Literature suggests that AA works through multiple mechanisms with the most compelling data coupled to the autonomic nervous system and neuroendocrine system. Curriculums designed to teach AA and aid in implementation have been published. CONCLUSION: AA is an accessible, effective means of pain relief. AA is relatively straightforward to learn, and protocols and curriculums exist to teach healthcare professionals this valuable skill. Overcoming implementation barriers, including patient education, are essential next steps.

This review was written to analyze the current research on an increasingly popular pain relief treatment, auricular acupuncture. Auricular acupuncture has been an effective method of pain relief for patients with short-term pain. People who experienced pain after surgery and received auricular acupuncture experienced a decrease in pain and pain medications. Patients with chronic pain who underwent auricular acupuncture experienced pain relief and an increase in their functional abilities. Auricular acupuncture is thought to affect the body's autonomic nervous system and neuroendocrine system as it creates its source of pain relief for the body. Auricular acupuncture is increasingly popular in the education of healthcare workers and clinical practice. Research shows auricular acupuncture is an effective, easy, and less expensive method of pain relief, whose growth in pain management use may benefit from further education, especially for patients.

Efficacy of auricular acupressure on lung function among chronic obstructive pulmonary disease: A meta-analysis of randomised controlled trials.

OBJECTIVES: To systematically evaluate the efficacy of auricular acupressure on lung function, sleep quality and quality of life in chronic obstructive pulmonary disease patients. BACKGROUND: Auricular acupressure has been increasingly used in chronic obstructive pulmonary disease patients, such as lung function and sleep quality, but the efficacy has not yet been unified. DESIGN: A meta-analysis of randomised controlled trials. METHODS: Randomised controlled trials comparing auricular acupressure intervention with non-auricular acupressure intervention in chronic obstructive pulmonary disease patients were included. We searched English databases and Chinese databases from the inception to 26 December 2022. The risk of bias was assessed by the Cochrane risk of bias tool. The PRISMA statement was used to report a meta-analysis. RESULTS: A total of 12 randomised controlled trials with 987 chronic obstructive pulmonary disease patients were included. The meta-analysis showed that auricular acupressure had significant differences in improving lung function, including FEV1 (MD = 0.29, 95% CI: 0.21 to 0.37, p < .0001), FVC (MD = 0.24, 95% CI: 0.14 to 0.34, p < .0001) and FEV1/FVC (MD = 4.70, 95% CI: 3.63 to 5.78, p < .0001). There was also a positive effect on sleep quality (MD = -0.71, 95% CI: -0.89 to -0.53, p < .0001) and quality of life (MD = -3.20, 95% CI: -3.92 to -2.49, p < .0001). CONCLUSIONS: The results indicated auricular acupressure had a positive efficacy in chronic obstructive pulmonary disease patients to improve lung function, sleep quality and quality of life, but these results should be treated with caution due to the low quality of included studies. Future researchers need to conduct more high-quality randomised controlled trials to provide a solid basis to demonstrate the efficacy of auricular acupressure in chronic obstructive pulmonary disease patients. RELEVANT TO CLINICAL PRACTICE: Auricular acupressure has the advantages of being non-invasive, convenient and without significant side effects. This review suggested auricular acupressure could be considered a non-pharmacological intervention for patients. Clinical nurses can teach chronic obstructive pulmonary disease patients to perform auricular acupressure to help self-manage complications. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

The curative efficacy of auricular comprehensive therapy on menstrual migraine and its effect on serum prostaglandin. / è€³ç©´ç»¼åˆç–—æ³•æ²»ç–—æœˆç»æ€§åå¤´ç—›æ‚£è€ ä¸´åºŠç–—æ•ˆåŠå¯¹è¡€æ¸ å‰åˆ—è ºç´ çš„å½±å“.

OBJECTIVES: To observe the curative efficacy of auricular comprehensive therapy on menstrual migraine(MM) and its effect on serum prostaglandin F2α(PGF2α), prostaglandin E2(PGE2) contents and ratio, so as to explore its possible mechanism. METHODS: A total of 66 patients with MM of liver-fire syndrome were randomly divided into observation group (33 cases, 2 cases dropped off) and control group (33 cases, 2 cases dropped off), and 20 healthy women were included in the normal group. Patients in the control group were given flunarizine hydrochloride capsules orally, twice a day, for 3 consecutive weeks. Patients in the observation group were treated with auricular comprehensive therapy, starting 2-5 days before menstrual cramps, once a week, for a total of 3 weeks. The visual analogue scale (VAS) and migraine score were evaluated before and after treatment, and follow-up for 1 and 2 menstrual cycles. Serum PGF2α and PGE2 contents were measured before and after treatment, and the PGF2α/PGE2 ratio was calculated. The clinical effective rates in the two groups were calculated. RESULTS: After treatment and follow-up for 1 and 2 menstrual cycles, the VAS scores, headache degree, the frequency and duration of headache attacks, as well as accompanying symptoms of the observation and control groups were lower than those before treatment(P<0.05), and those of the observation group was lower than those of the control group(P<0.05). Before treatment, the PGF2α contents in the observation and control group were significantly higher(P<0.05), while the PGE2 contents lower(P<0.05) and PGF2α/PGE2 ratio higher(P<0.05) than those in the normal group. After treatment, the serum PGF2α contents in the observation and control group were significantly reduced compared with which before treatment(P<0.05), and were lower in the observation group than that in the control group (P<0.05). The serum PGE2 contents in the observation and control groups were significantly increased after treatment compared with which before treatment(P<0.05), with the contents in the observation group higher than that in the control group(P<0.05). The serum PGF2α/PGE2 ratio in the observation and control group was significantly reduced after treatment compared with which before treatment(P<0.05), with the control group higher than the normal group(P<0.05), and the observation group lower than the control group(P<0.05). The clinical effective rate of the observation group was 93.5% (29/31), and that of the control group was 77.4% (24/31). The effective rate of the observation group was significantly higher than that of the control group(P<0.05). CONCLUSIONS: The curative efficacy of auricular comprehensive therapy on MM with liver-fire syndrome is significantly better than that of oral flunarizine hydrochloride capsules, especially in relieving hea-daches, reducing the frequency and duration of headache attacks, as well as accompanying symptoms. Its mechanism may be related to regulating the abnormal PGF2α and PGE2 contents of patients and reducing the ratio of PGF2α/PGE2.

Acupuncture Treatment for Generalized Anxiety Disorder by Activating the Vagus Nerve and Improving Heart-Rate Variability and Heart-Rhythm Coherence, A Case-Series Study.

Objective: The goal of this case series was to observe the effectiveness of acupuncture for reducing sympathetic stress and anxiety-related symptoms in generalized anxiety disorder. The effect of acupuncture on the balance of the autonomic nervous system was also examined. Materials and Methods: This was a case-series study with 10 participants enrolled. Each participant received acupuncture treatment 2 times per week for 4 weeks. Participants were evaluated with the Generalized Anxiety Disorder-7 (GAD-7) scale and the Body Perception Questionnaire-Short Form (BPQ-SF) before and after the treatment program. Heart-rate variability heart-rhythm coherence (HRC) was also assessed during each acupuncture session. Results: Five participants completed the program. Both GAD-7 and BPQ mean scores showed significant reductions. The mean HRC high-coherence ratio also increased significantly after acupuncture treatment. No adverse effects occurred. Conclusions: Acupuncture may be an effective therapy for sympathetic stress and anxiety-related symptoms. The mechanism of action may be through activating the vagus nerve and improving the HRC high coherence ratio. It is feasible to conduct larger clinical trials with random controls, longer treatment durations, and long-term follow-ups to support the results of this study.

[Deep learning approach for automatic segmentation of auricular acupoint divisions].

The automatic segmentation of auricular acupoint divisions is the basis for realizing intelligent auricular acupoint therapy. However, due to the large number of ear acupuncture areas and the lack of clear boundary, existing solutions face challenges in automatically segmenting auricular acupoints. Therefore, a fast and accurate automatic segmentation approach of auricular acupuncture divisions is needed. A deep learning-based approach for automatic segmentation of auricular acupoint divisions is proposed, which mainly includes three stages: ear contour detection, anatomical part segmentation and keypoints localization, and image post-processing. In the anatomical part segmentation and keypoints localization stages, K-YOLACT was proposed to improve operating efficiency. Experimental results showed that the proposed approach achieved automatic segmentation of 66 acupuncture points in the frontal image of the ear, and the segmentation effect was better than existing solutions. At the same time, the mean average precision (mAP) of the anatomical part segmentation of the K-YOLACT was 83.2%, mAP of keypoints localization was 98.1%, and the running speed was significantly improved. The implementation of this approach provides a reliable solution for the accurate segmentation of auricular point images, and provides strong technical support for the modern development of traditional Chinese medicine.

Auricular Acupuncture Prior to Menstruation Can Reduce Primary Dysmenorrhea: A Randomized Controlled Trial.

Objective: Primary dysmenorrhea is a common condition that impacts quality of life significantly. Auricular therapies have shown promise for treating primary dysmenorrhea, but there is a lack of evidence specifically for auricular acupuncture (AA). This study evaluated the safety and efficacy of AA for managing primary dysmenorrhea. Materials and Methods: A randomized, double-blinded controlled trial was conducted on 90 females with primary dysmenorrhea: an AA group; n = 45) and a sham-AA (SA) group; n = 45. Specific ear acupoints (i.e., Uterus, Endocrine, Shenmen, Subcortex, Liver, and Kidney) were used for the intervention, which was 1 or 2 days prior to the expected menstruation onset. Outcomes were visual analogue scale (VAS) scores, ibuprofen needs, and adverse events (AEs). Results: The AA group had significantly lower VAS scores, compared to the SA group at menstruation onset and for up to 12 hours (mean differences [MDs] and 95% confidence intervals [CIs]: -1.08 [-1.96, -0.21] and -1.17 [-2.16, -0.18], respectively). Both groups had reductions in pain levels, compared to the prior menstrual cycle; the AA group had a significantly greater improvement. The AA group needed fewer ibuprofen tablets (MD: -0.28; 95% CI: -0.58, 0.00]). AEs were mild pain and irritation at insertion sites, all resolved spontaneously with no lasting effects. Conclusions: AA is safe. It may be effective for managing primary dysmenorrhea. Further studies are warranted on AA's effectiveness in diverse populations and extended times.

Migraine Symptoms Induced by an Auricular Piercing in a 27-Year-Old Female: A Case Report.

Introduction: Migraines are common and debilitating, and have high direct and indirect costs. They can be difficult to treat, and many patients make use of alternative medicine techniques. One of these is acupuncture applied to locations on the auricle thought to modulate migraine symptoms. Some patients obtain piercings in these locations in hopes of relieving their symptoms; however, the literature does not address the possibility of migraine symptoms being worsened or even induced by such piercings. Case Presentation: We present a case of a 27-year-old female with a history of transient hemiplegia without headaches who developed headaches, visual disturbances, and nausea after a piercing of the inferior crus of her left antihelix (known as a rook piercing). No abnormalities were found on workup, and symptoms were treated with supportive care. After removing the piercing 9 months later, the patient's symptoms resolved. Conclusion: The mechanism linking the piercing with the migraine symptoms is unclear, but may involve modulation of trigeminal or vagal pain pathways, as both of these cranial nerves innervate this area of the auricle. Regardless, in patients presenting with migraine symptoms, history and physical exam should not overlook piercings as potential contributory factors.

Heart rate variability and cold-induced vascular dilation after stimulation of two different areas of the ear: a prospective, single-blinded, randomized crossover study.

BACKGROUND: Both noninvasive transauricular vagus nerve stimulation (taVNS) and traditional medical practice (TMP), such as auriculotherapy, use the auricle as a starting point for stimulation, but with two different conceptual frameworks: taVNS depends on vagal afferences to account for its effects, whereas TMP requires stimulation of the ear with high topographical accuracy regardless of the afferent nerves. The aim of this study was to measure heart rate variability (HRV) and cold water-induced vasodilation (CIVD) after puncturing two different ear points with the same afference but that should have opposite effects according to TMP. METHODS: Ten healthy subjects were investigated in this single-blinded crossover study over three sessions. In the first session, sympathetic activation was performed via cold water immersion of the right hand, with recordings taken from multiple fingers. HRV was assessed in the time domain (square root of the mean squared differences of NN intervals (RMSSD)) and frequency domain (low (LF) and high frequencies (HF)). In the second and third sessions, the same skin immersion test was performed, and mechanical stimulation was applied to the ear at two different points on the internal surface of the antitragus, one with alleged parasympathetic activity and the other with alleged sympathetic activity. The stimulation was done with semipermanent needles. RESULTS: Stimulation of the point with alleged parasympathetic activity immediately resulted in a significant decrease in RMSSD in 75% of the subjects and in LF in 50% of the subjects, while stimulation of the point with alleged sympathetic activity resulted in an increase in HF and RMSSD in 50% of the subjects. Stimulation of these points did not affect the CIVD reflex. The 20 min cold water immersion induced an immediate decrease in LF and the LF/HF ratio and an increase in HF. The skin temperature of the nonimmersed medius significantly decreased when the contralateral hand was immersed, from 34.4 °C to 31.8 °C. CONCLUSIONS: Stimulation of two different ear points innervated by the same afferent nerves elicited different HRV responses, suggesting somatotopy and a vagal effect beyond vagal afferences. These results are not in accordance with the claims of TMP. TRIAL REGISTRATION: NCT04130893 (18/10/2019) clinicaltrials.com.

Ear-Marking Relief: A Meta-Analysis on the Efficacy of Auricular Acupressure in Alleviating Anxiety Disorders.

BACKGROUND: The increasing worldwide mental health crisis, notably anxiety, emphasizes the urgency for available and effective interventions. Traditional therapies, although beneficial, pose limitations due to their considerable costs and possible adverse effects, thereby inviting alternative treatments such as auricular acupressure (AA). This non-pharmacological, integrative method, underpinned by Eastern and Western medical principles, presents a significant prospect for managing anxiety. OBJECTIVE: This study aims to evaluate the existing evidence on the efficacy of AA in reducing anxiety, as elucidated through a systematic review. METHODS: A comprehensive search of randomized controlled trials was conducted across various databases: the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wan Fang, and Database for Chinese Technical Periodicals (VIP). Two reviewers retrieved the pertinent studies and assessed their methodological quality. A meta-analysis was then conducted, incorporating data from all relevant time points. RESULTS: Upon examining 25 studies encompassing 1,909 participants, it was discerned that AA significantly diminished anxiety (SMD = -1.1074; 95% confidence interval, -1.348 to -0.801; z = 7.70, p < 0.01). Subgroup analyses indicated that neither an increased number of auricular points nor extended intervention augmented effects. Larger effect sizes were associated with probing and avoidance of sham acupressure. Notably, 23 of the 25 studies exhibited some bias, suggesting further research is necessary. CONCLUSIONS: The extant evidence advocates for AA as an effective supplementary intervention that reduces patient anxiety. The results hint at a potential placebo effect elicited by sham acupressure, necessitating rigorous control group definitions in future inquiries. The study findings suggest that fewer acupressure points and shorter intervention durations could effectively alleviate anxiety symptoms. Nonetheless, the significant heterogeneity across the studies underscores the requirement for more stringent research methodologies to substantiate these conclusions.Die weltweit zunehmende Krise der psychischen Gesundheit, vor allem von Angstzuständen, zeigt, dass dringend verfügbare und wirksame Interventionen erforderlich sind. Herkömmliche Therapien sind zwar hilfreich, werden aber durch ihre hohen Kosten und möglichen unerwünschten Wirkungen eingeschränkt, so dass alternative Behandlungen wie die Ohrakupressur gefragt sind. Diese nicht-pharmakologische, integrative Methode, die sich auf östliche und westliche medizinische Prinzipien stützt, stellt eine bedeutsame Perspektive für die Behandlung von Angstzuständen dar.Ziel dieser Studie ist es, die vorhandenen Evidenzen für die Wirksamkeit der Ohrakupressur (auricular acupressure, AA) zur Verringerung von Angstzuständen, die in einer systematischen Übersichtsarbeit ermittelt wurden, zu bewerten.Es wurde eine umfassende Suche nach randomisierten kontrollierten Studien in verschiedenen Datenbanken durchgeführt: Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, Web of Science, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), Wan Fang und Database for Chinese Technical Periodicals (VIP). Zwei Gutachter suchten die einschlägigen Studien heraus und bewerteten ihre methodische Qualität. Anschliessend erfolgte eine Metaanalyse, bei der Daten aller relevanten Zeitpunkte berücksichtigt wurden.Die Untersuchung von 25 Studien mit 1'909 Teilnehmern ergab, dass die Ohrakupressur (AA) Angstzustände signifikant verringerte (SMD = −1,1074; 95%-KI: −1,348 bis −0,801; z = 7,70, p < 0,01). Subgruppenanalysen zeigten, dass die Effekte weder durch eine höhere Anzahl von Ohrpunkten noch durch eine längere Intervention verstärkt wurden. Grössere Effektstärken waren mit Sondenverwendung und Vermeidung von Scheinakupressur assoziiert. Hervorzuheben ist, dass 23 der 25 Studien eine gewisse Verzerrung aufwiesen, weshalb weitere Untersuchungen erforderlich sind.Die vorhandene Evidenzlage stützt die Ohrakupressur (AA) als wirksame unterstützende Intervention, die die Angst der Patienten verringert. Die Ergebnisse deuten auf einen potenziellen Placeboeffekt durch Scheinakupressur hin, so dass in künftigen Untersuchungen strenge Kontrollgruppendefinitionen erforderlich sind. Die Studienergebnisse sprechen dafür, dass eine geringere Anzahl von Akupressurpunkten und kürzere Interventionszeiten die Angstsymptome wirksam lindern können. Die starke Heterogenität der Studien zeigt allerdings, dass strengere wissenschaftliche Methoden erforderlich sind, um diese Schlussfolgerungen zu untermauern.

Modulating the default mode network: Antidepressant efficacy of transcutaneous electrical cranial-auricular acupoints stimulation targeting the insula.

BACKGROUND: Transcutaneous electrical cranial-auricular acupoint stimulation (TECAS) is a novel non-invasive therapy for major depressive disorder (MDD) that stimulates acupoints innervated by the trigeminal and auricular vagus nerves. However, there are few neuroimaging studies involving the TECAS for the treatment of MDD. Therefore, this study aimed to investigate the treatment response and neurological effects of TECAS using resting-state functional magnetic resonance imaging (rs-fMRI). METHOD: A total of 34 patients with mild-to-moderate MDD and 34 demographically matched healthy controls (HCs) were recruited. After an eight-week treatment the primary outcome was clinical response, defined as a baseline-to-endpoint ≥ 50 % reduction in the 17-item Hamilton Depression Rating Scale (HAMD-17). The low-frequency fluctuations (ALFF) method were used to investigate the brain abnormalities of MDD patients and HCs, and altered brain networks were analyzed between pre- and post-treatment using seed-based functional connectivity (FC) analysis. RESULTS: We found no significant differences in terms of gender, age, and years of education between the two groups. After treatment, the response rate was 58.82 %. Compared to HCs, MDD patients showed lower ALFF values in the left insula(t = -4.298,P < 0.005), the insula-based FC revealed in the right middle frontal gyrus (MFG)/ right superior frontal gyrus, orbital part (ORBsupmed) (t = -5.29,P < 0.005) and the right anterior cingulate gyrus (ACC)were decreased (t = -6.08,P < 0.005). Furthermore, Compared to pre-treatment, abnormal FC values in the ACC /orbital superior frontal gyrus (SFG) (t = 3.42,P < 0.005) and left superior frontal gyrus (SFG)/ supplement motor area (SMA) were enhanced (t = 3.34,P < 0.005). CONCLUSION: TECAS exhibits antidepressant efficacy, particularly influencing the insula-based functional connections within the Default Mode Network (DMN) related to emotion processing in individuals with MDD.

Daith piercing: Revisited from the perspective of auricular acupuncture systems. A narrative review.

BACKGROUND: Daith piercing is a special ear-piercing method that punctures the crus of the helix. The penetrated site at the ear's innermost point is assumed to stimulate a pressure point associated with the vagus nerve. It has been reported that the pierced spot relieves migraine and tension-type headaches by activating vagal afferents, leading to the inhibition of neurons in the caudal trigeminal nucleus via the nucleus tractus solitarii. OBJECTIVE: The objective of this narrative literature review is to summarize the current state of knowledge concerning daith piercing for the treatment of migraine and tension-type headaches from the perspectives of the Chinese and Western auricular systems. METHODS: PubMed and China National Knowledge Infrastructure databases were searched using the keywords "daith piercing," "auricular points," "headache," and "acupuncture" from database inception to September 1, 2023. Only studies on humans were eligible; otherwise, no further restrictions were applied to the study designs, type of headache, or patient population of the identified articles. Bibliographies of all eligible studies were screened for further eligible studies. The main outcome of interest was a quantitative measure of pain relief by daith piercing. Secondary outcomes were relapse time of headache and further outcomes related to daith piercing, if available. RESULTS: From a total of 186 identified articles, one retrospective study and three case reports fulfilled the inclusion criteria. No clinical trial was identified. The obtained studies describe patients experiencing chronic headaches undergoing daith piercing without changing or reducing their usual medication. In all case studies and the retrospective study, patients reported substantial reductions in pain immediately after daith piercing; however, headache symptoms recurred several weeks to months thereafter. From the perspective of the Chinese and Western auricular systems, no sufficient explanation for the described treatment effect of daith piercing was found. CONCLUSION: The available literature, combined with the reported recurrence of pain as well as the associated side effects of daith piercing, indicate that current evidence does not support daith piercing for the treatment of migraine, tension-type headaches, or other headache disorders. PLAIN LANGUAGE SUMMARY: This paper summarizes what we know about Daith piercing (DP) for chronic migraine and tension-type headache and discusses how DP might work. Current evidence does not support DP as an effective treatment of chronic migraine and tension-type headache. These findings might assist clinicians in discussing this subject with patients as well as guide future research.

Development and Validation of an Auricular Acupuncture Protocol for the Management of Chemotherapy-Induced Nausea and Vomiting in Cancer Patients.

Auricular acupuncture (AA) has been used to manage chemotherapy-induced nausea and vomiting (CINV). However, the application of the technique varies widely among the clinical trials that test its effectiveness. The aim of the present study was to develop and clinically validate an AA protocol for the management of CINV in cancer patients. This study was carried out in two stages: (1) development of the AA protocol for the management of CINV and (2) clinical validation of the protocol. The content validity of the protocol was determined by a panel of specialists, with an agreement rate ranging from 85.7% to 100%. In the clinical validation, when administered to cancer patients, the protocol developed has been shown to reduce the incidence, frequency, severity, and length of nausea and vomiting following chemotherapy, as well as the severity of nausea and anticipatory nausea following chemotherapy. This protocol needs to be tested in future studies, including a pilot study with a sham group and a randomized clinical trial, in order to further evaluate its feasibility, acceptability, safety, and clinical usefulness for the management of CINV.

Transcutaneous auricular vagus nerve stimulation therapy in patients with cognitively preserved structural focal epilepsy: A case series report.

OBJECTIVE: Transcutaneous auricular vagus nerve stimulation (taVNS) was performed in two patients suffering structural focal epilepsy with preserved intellectual ability to show the feasibility of taVNS for specific patient groups. CASE PRESENTATIONS: Patient 1 was a 24-year-old woman with frontal lobe epilepsy who had weekly hyperkinetic seizures despite multiple anti-seizure medications. Patient 2 was a 27-year-old woman with parietal lobe epilepsy and focal cortical dysplasia in the vicinity of the lipoma in the corpus callosum. She experienced weekly focal-impaired awareness seizures even with anti-seizure medication. taVNS was applied to the left earlobe of both patients at 1.5 mA, 25 Hz, 250 µs pulse width, and 30 s stimulation with 30 s rest for 4 h per day. Over an 8-week baseline and 20 weeks of stimulation, the rate of reduction in seizure frequency was evaluated, along with quality-of-life using the Short-Form 36-Item Health survey. RESULTS: At baseline, we measured up to 11 and 12 focal seizures per week in Patient 1 and 2, respectively, with both patients achieving seizure freedom after 4 and 20 weeks taVNS, respectively. Patient 1 and 2 were observed for 18 and 14 months, respectively, including the clinical trial and follow-up observation period. Quality-of-life ratings increased in both patients, and no significant adverse events occurred during the study period. During the maintenance period after 20 weeks, seizures remained absent in Patient 1, and seizures remained reduced in Patient 2. CONCLUSION: Our results demonstrate that taVNS may be a promising tool for structural focal epilepsy with preserved cognitive function. A multicenter double-blind clinical trial is needed to confirm the role of taVNS as an anti-seizure tool.
