ABSTRACT
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.

PURPOSE: To evaluate the prevalence and risk factors of age-related macular degeneration (AMD) in the Korean population. METHODS: In this cross-sectional study based on the Korea National Health and Nutrition Examination Survey (2017-2020) data 13,737 participants aged ≥ 40 years with assessable fundus images were included. The prevalence and risk factors of AMD were evaluated. The prevalence of early AMD, geographic atrophy (GA), and neovascular AMD were also assessed. Logistic regression analyses were used to identify risk factors. RESULTS: The prevalence (95% confidence interval [CI]) of AMD was 13.94% (13.15-14.72). The prevalence (95% CI) of early AMD, GA, and neovascular AMD was 13.07% (12.29-13.85), 0.26% (0.17-0.35), and 0.61% (0.47-0.75), respectively. The prevalence increased with age; it was 3.61%, 11.33%, 20.31%, 31.37%, and 33.98% in participants in their 40s, 50s, 60s, 70s, and ≥ 80 years, respectively. In multivariate analysis, AMD was positively associated with older age (p < 0.001; odds ratio [OR], 1.08; 95% CI, 1.07-1.09), male sex (p = 0.014; OR, 1.27; 95% CI, 1.05-1.53), and lower degree of education (p < 0.001; OR, 1.36 (for junior high school graduates); 95% CI, 1.12-1.65). CONCLUSIONS: AMD was detected in approximately one-third of individuals aged ≥ 70 years, thus indicating that AMD is a common disease among older Koreans. Regular fundus examinations in populations with risk factors for AMD as well as education on methods to prevent or delay AMD progression, such as the Mediterranean diet, are necessary.
ABSTRACT
Obesity is a serious global health challenge, closely associated with numerous chronic conditions including type 2 diabetes. Anemarrhena asphodeloides Bunge (AA) known as Jimo has been used to address conditions associated with pathogenic heat such as wasting-thirst in Korean Medicine. Timosaponin A3 (TA3), a natural compound extracted from AA, has demonstrated potential therapeutic effects in various disease models. However, its effects on diabetes and obesity remain largely unexplored. We investigated the anti-obesity and anti-diabetic properties of TA3 using in vitro and in vivo models. TA3 treatment in NCI-H716 cells stimulated the secretion of glucagon-like peptide 1 (GLP-1) through the activation of phosphorylation of protein kinase A catalytic subunit (PKAc) and 5'-AMP-activated protein kinase (AMPK). In 3T3-L1 adipocytes, TA3 effectively inhibited lipid accumulation by regulating adipogenesis and lipogenesis. In a high-fat diet (HFD)-induced mice model, TA3 administration significantly reduced body weight gain and food intake. Furthermore, TA3 improved glucose tolerance, lipid profiles, and mitigated hepatic steatosis in HFD-fed mice. Histological analysis revealed that TA3 reduced the size of white adipocytes and inhibited adipose tissue generation. Notably, TA3 downregulated the expression of lipogenic factor, including fatty-acid synthase (FAS) and sterol regulatory element-binding protein 1c (SREBP1c), emphasizing its potential as an anti-obesity agent. These findings revealed that TA3 may be efficiently used as a natural compound for tackling obesity, diabetes, and associated metabolic disorders, providing a novel approach for therapeutic intervention.

We propose a hybrid technique that employs artificial intelligence (AI)-based segmentation and machine learning classification using multiple features extracted from the foveal avascular zone (FAZ)-a retinal biomarker for Alzheimer's disease-to improve the disease diagnostic performance. Imaging data of optical coherence tomography angiography from 37 patients with Alzheimer's disease and 48 healthy controls were investigated. The presence or absence of brain amyloids was confirmed using amyloid positron emission tomography. In the superficial capillary plexus of the angiography scans, the FAZ was automatically segmented using an AI method to extract multiple biomarkers (area, solidity, compactness, roundness, and eccentricity), which were paired with clinical data (age and sex) as common correction variables. We used a light-gradient boosting machine (a light-gradient boosting machine is a machine learning algorithm based on trees utilizing gradient boosting) to diagnose Alzheimer's disease by integrating the corresponding multiple radiomic biomarkers. Fivefold cross-validation was applied for analysis, and the diagnostic performance for Alzheimer's disease was determined by the area under the curve. The proposed hybrid technique achieved an area under the curve of [Formula: see text]%, outperforming the existing single-feature (area) criteria by over 13%. Furthermore, in the holdout test set, the proposed technique exhibited a 14% improvement compared to single features, achieving an area under the curve of 72.0± 4.8%. Based on these facts, we have demonstrated the effectiveness of our technology in achieving significant performance improvements in FAZ-based Alzheimer's diagnosis research through the use of multiple radiomic biomarkers (area, solidity, compactness, roundness, and eccentricity).

PURPOSE: To evaluate the bilateral involvement of age-related macular degeneration (AMD) in South Koreans. METHODS: This was a cross-sectional study of the Korean National Health and Nutrition Examination Survey (2017-2020). This study included 13,737 participants aged 40 years or older. Participants were evaluated to determine the prevalence of bilateral early and late AMD. In cases in which exudative AMD or geographic atrophy (GA) was diagnosed in a single eye, the fellow eye was evaluated to determine the presence and type of late AMD. RESULTS: The overall prevalence of bilateral AMD was 6.12% (95% confidence interval [CI], 5.63-6.61). The prevalence of bilateral early AMD was 5.71% (95% CI, 5.24-6.18), while that of late AMD was 0.14% (95% CI, 0.08-0.20). The prevalence of the bilateral involvement of late AMD increased with age. A 0.02% prevalence (95% CI, 0.00-0.06) of late AMD was observed in participants aged 50-59. The prevalence increased to 0.08% (95% CI, 0.00-0.18) in participants aged 60-69, while the prevalence in participants aged 70-79 and over 80 was 0.45% (95% CI, 0.12-0.78) and 1.97% (95% CI, 0.75-3.19), respectively. The prevalence of early AMD in one eye and late AMD in the fellow eye was 0.26% (95% CI, 0.16-0.36). CONCLUSIONS: An assessment of the incidence of AMD revealed that a significant number of persons had bilateral involvement. The treatment burden may significantly increase for participants with bilateral late AMD compared to those with unilateral involvement. Therefore, the study may be helpful with the establishment of private and national insurance policies.
ABSTRACT
BACKGROUND: This systematic review and meta-analysis evaluated the efficacy of electroacupuncture for the treatment of obesity. METHODS: We searched 8 electronic databases for articles published between 2005 and 2021, including only randomized controlled trials (RCTs) in the review. The intervention groups received either electroacupuncture alone or electroacupuncture with standard care, whereas the control groups received sham electroacupuncture, standard care, or no treatment. The primary outcome was the body mass index (BMI), and the secondary outcomes were the body weight (BW), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), body fat mass, body fat percentage, and adverse effects. Continuous outcome data are presented as mean differences (MDs) with 95% confidence intervals (CIs). RESULTS: This systematic review and meta-analysis included 13 RCTs involving 779 participants. Results revealed that the BMI (MD: -0.98; 95% CI: -1.35 to -0.61), BW (MD: -1.89; 95% CI: -2.97 to -0.80), WC (MD: -2.67; 95% CI: -4.52 to -0.82), and WHR (MD: -0.03; 95% CI: -0.06 to -0.01) were significantly improved in the intervention groups compared with those in the control groups. Adverse effects were reported in 5 studies. The most commonly used acupoint in the abdomen was ST25, whereas the most commonly used acupoints in other regions were ST36 and SP6 for the treatment of obesity. ST25 was the most commonly used acupoint connected by electroacupuncture. CONCLUSION: This systematic review and meta-analysis suggested that electroacupuncture is an effective and safe therapy for simple obesity. To increase the reliability of this study, further detailed, long-term studies should be conducted on the effects of electroacupuncture on obesity.

Background: Moxibustion has been used in the treatment and prevention of obesity. However, there has been no systematic review or meta-analysis conducted on the use of moxibustion on obesity treatment. This study aimed to evaluate the role of moxibustion in the treatment of obesity. Methods: The Cochrane Central Register of Controlled Trials, EMBASE, and MEDLINE/PubMed databases were searched to identify all randomized controlled trials (RCTs) that evaluated the effect of moxibustion on obesity. The primary outcome was body weight. The secondary outcomes were the body mass index (BMI), waist circumference (WC), hip circumference (HC), and waist-to-hip ratio (WHR). The risk of bias assessment and meta-analysis were conducted using the Cochrane Collaboration tool. Results: Eleven RCTs involving 761 participants were included in this systematic review and meta-analysis. Other interventions that were included in the analyses were manual acupuncture, electroacupuncture, embedding therapy, herbal medicine, and diet control. Moxibustion combined with other interventions resulted in a significant improvement in body weight reduction (mean difference [MD] -3.32, 95% confidence interval [CI: -4.25 to -2.38]; I2 = 17%), BMI (MD -1.51, 95% CI [-1.88 to -1.14]; I2 = 76%), and WC (MD -2.82, 95% CI [-3.50 to -2.13]; I2 = 75%), but did not improve HC (MD -2.05, 95% CI [-4.21 to 0.11]; I2 = 0%) or WHR (MD -0.01, 95% CI [-0.03 to 0.01]; I2 = 57%). Conclusions: Moxibustion can be used with other interventions to improve body weight, BMI, and WC in people with obesity. However, the conclusions of this review should be cautiously applied to clinical practice because most of the included studies had a high or unclear risk of bias.

We analyzed the papers by annual publication, research fields, nations, affiliations, authors, journals, and keywords. VOSviewer software was used to visualize the bibliometric analysis and results. A total of 440 papers were included in the analysis. Results: The number of publications has gradually increased every year, and neuroscience has become the most actively studied field. Neural Regeneration Research journal and China had the most publications. Fujian University of Traditional Chinese Medicine, as an affiliated institute, published the most articles. Chen Lidian and Tao Jing presented the largest number of papers, making them the leading contributors in this field. Four clusters were created by analyzing keywords, such as "neuroprotection," "clinical rehabilitation," "neuroplasticity," and "pretreatment-induced tolerance". Conclusion: This study is the first to analyze the research trends in electroacupuncture as a treatment for stroke using the VOSviewer. It shows the current state of research in the field by visualizing research trends and hotspots. This will help offer reference data for future studies.
ABSTRACT
BACKGROUND: Cupping therapy is a common practice in Korean medicine. Despite developments in this clinical and research area, the current knowledge is insufficient to identify the effects of cupping therapy on obesity. We aimed to assess the effects and safety of cupping therapy on obesity by performing a systematic review and meta-analysis of the effects of cupping therapy. METHODS: A systematic search of databases was conducted, including MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, Citation Information by the National Institute of Informatics, KoreaMed, Oriental Medicine Advanced Searching Integrated System, and ScienceON, for full-text randomized controlled trials (RCTs) published through January 14, 2023, with no language restrictions. The experimental groups received cupping therapy combined with traditional Chinese medicine (TCM) and conventional therapy. The control groups received no treatment, conventional therapy, or TCM treatments alone. The experimental and control groups were compared in terms of body weight (BW), body mass index (BMI), hip circumference (HC), waist circumference (WC), waist-hip ratio (WHR), and body fat percentage (BFP). We evaluated the risk of bias using the 7 domains stipulated by the Cochrane Collaboration Group and performed a meta-analysis using Cochrane Collaboration software (Review Manager Software Version 5.3). RESULTS: A total of 21 RCTs were included in this systematic review and meta-analysis. The analysis revealed improvements in BW (Pâ <â .001), BMI (Pâ <â .001), HC (Pâ =â .03), and WC (Pâ <â .001). However, there were no clinically significant changes in WHR (Pâ =â .65) or BFP (Pâ =â .90), both of which had very low certainty of evidence. No adverse events were reported. CONCLUSION: Overall, our results show that cupping therapy can be used to treat obesity in terms of BW, BMI, HC, and WC and is a safe intervention for the treatment of obesity. However, the conclusions of this review should be interpreted with caution in clinical practice because of the uncertain quality of the included studies.

BACKGROUND: This review aimed to verify the clinical effects of traditional Chinese medicine in collaboration with conservative conventional medicine for lumbar herniated intervertebral discs (LHIVD). METHODS: The CENTRAL, EMBASE, MEDLINE/PubMed, JMAS, CNKI, and seven Korean databases were searched using pre-planned strategies. The risk of bias was assessed using the Cochrane Collaboration tool and a meta-analysis was conducted accordingly. RESULTS: Twenty-eight randomized controlled trials (RCTs) were included in this systematic review and meta-analysis. All RCTs included 2746 participants. The experimental group showed more significant improvements in VAS (Mean differences (MD) -1.61, 95% Confidence Intervals (CI) [-2.44, -0.79]; I2 = 98%), Oswestry Disability Index (ODI) (MD -8.52, 95% CI [-11.71, -5.34]; I2 = 96%), and Japanese Orthopaedic Association (JOA) scores (MD 4.83, 95% CI [3.49, 6.17]; I2 = 85%) than the control group. However, the difference in the incidence of adverse events between the experimental and control groups was not significant (Relative Risk (RR) 0.05, 95% CI [0.23, 1.10]; I2 = 46%). CONCLUSION: Traditional Chinese medicine in collaboration with conservative conventional medicine can be used to relieve pain and facilitate better function of the lumbar spine in lumbar herniated intervertebral disc cases. However, this conclusion should be applied with caution in clinical practice owing to the low quality of the included studies.

This study compared the characteristics of posterior vitreous detachment (PVD)-related and glaucomatous optic disc hemorrhage (DH). Fundus photographs of eyes with PVD-related DH (PVD group) and glaucomatous DH (glaucoma group) were reviewed. The shape, type, layer, location (clock-hour sector), and DH/disc area (DH/DA) ratio of DH were investigated. In the PVD group, DH presented as a flame (60.9%), splinter (34.8%), and dot or blot (4.3%) shape. However, most of the glaucomatous DH revealed a splinter shape (92.3%), followed by a flame shape (7.7%, p < 0.001). In the PVD group, the most common type of DH was cup margin type (52.2%), whereas, in the glaucoma group it was disc rim type (53.8%, p = 0.003). Both PVD-related and glaucomatous DH were most commonly observed in the 7 o'clock sector. In the PVD group, DH was also found in the 2 and 5 o'clock sectors (p = 0.010). Mean DH/DA ratio in PVD group (0.15 ± 0.19) was greater than in glaucoma group (0.04 ± 0.04, p < 0.001). PVD-related DH showed a higher frequency of flame shape, cup margin type, nasal location, and greater area compared to the glaucomatous DH.

PURPOSE: To evaluate the relationship between interocular asymmetries of corneal hysteresis (CH) and visual field defects in Korean patients with glaucoma. METHODS: A total of 444 eyes from 222 participants with glaucoma in at least one eye were enrolled. CH was measured using an ocular response analyzer (Reichert Technologies Inc). Eyes of each participant were classified into "better eye" and "worse eye" based on the mean deviation (MD) value of visual field test. The correlation between interocular differences in intraocular pressure, axial length, central corneal thickness, CH, and MD values was evaluated using Spearman correlation analysis. To exclude the possible effect of antiglaucoma medication on corneal properties, additional analyses were performed on eyes without any glaucoma treatment at the time of CH measurement (treatment-naive group). RESULTS: Median (interquartile range) MD value was -3.71 dB (-6.87 to -1.30 dB) in the better eye and -10.20 dB (-16.32 to -5.62 dB) in the worse eye. When the correlation between the asymmetry of the MD value and asymmetry of intraocular pressure, axial length, central corneal thickness, and CH were evaluated, only interocular differences in CH were significantly associated with interocular differences in MD values (rho = 0.214, p = 0.001). Among the 222 participants, 60 (27.0%) were treatment-naive group. In these eyes, interocular differences in CH were also significantly associated with interocular differences in the MD values (rho = 0.285, p = 0.029). CONCLUSIONS: The interocular asymmetry of CH was significantly correlated with the interocular asymmetry of visual field defects in glaucoma.

Depression is a common illness worldwide. Acupuncture is used as an alternative to non-pharmacological therapy. This study aimed to identify the development and global trends in the study of acupuncture therapy for depression over the past two decades using a bibliometric analysis. Articles published between 2001 and 2020 on acupuncture for depression were retrieved from the Web of Science database. Extracted information included authors, organizations, countries, keywords, and journals. The VOSviewer program was used to visualize the impacts and network hubs of the keywords, authors, and affiliations. Analyses of 871 original and review articles revealed that the number of publications has continually increased over the past 20 years. China has published the maximum number of articles, followed by the United States and South Korea. As for research areas, integrative complementary medicine was most well represented in terms of the number of articles. Co-occurrence analysis of keywords indicated that each five sub-group cluster (including "pain related to depressive symptoms," "CAM therapies of depression," "comorbid disease or symptoms of depression," "clinical trials of depression," and "mechanism of acupuncture on depression") has its own impact keyword. The most recent keywords were "protocol" and "systematic review," whereas early keywords were "acupuncture analgesia" and "St john's wort." Co-authorship analysis of authors and organizations revealed 4 influential authors and 2 organizations in the field of acupuncture for depression. The present study provided influential keywords that show comorbid symptoms, treatments, and mechanism. Additionally, it revealed the influential persons or groups related to acupuncture therapy for depression.

OBJECTIVE: To assess and compare the visual performance of two extended depth-of-focus intraocular lenses (IOLs), Tecnis Symfony (Symfony; Johnson & Johnson Vision, Santa Ana, CA) and Acrysof IQ Vivity (Vivity; Alcon Inc, Fort Worth, TX). METHODS: The medical records of patients undergoing cataract surgery with Symfony or Vivity implantation from May 2021 to September 2021 and the data available for the 3-month follow-up were reviewed. The main measures of the findings were uncorrected and corrected distance (4 m) visual acuity (VA), uncorrected intermediate (66 cm) VA (UIVA) and uncorrected near (40 and 33 cm) VA (UNVA), refractive error (RE), defocus profiles analysis, optical quality parameters, and patient-reported quality of vision questionnaire results. RESULTS: Of the 40 patients, 19 patients (31 eyes) were treated with the Symfony IOL and 21 (32 eyes) with the Vivity IOL. The mean age of the patients was 63.4±7.8 (range, 40-76) years in the Symfony group and 61.8±9.7 (range, 40-77) years in the Vivity group. There was no meaningful difference between the two groups in the preoperative parameters, except that the Vivity group had a better CDVA. Among the main measures of results, there was no statistically significant difference, except for the UNVA (33 cm). The Symfony group also showed a smoother defocus curve at 3 months postoperatively. CONCLUSION: There was no significant difference between the two groups regarding uncorrected/corrected distance VA, UIVA, UNVA (40 cm), RE, optical quality parameters, and patient-reported quality of vision questionnaire results. The Symfony group demonstrated a significantly superior UNVA (33 cm) and a smoother defocus curve with a broad landing zone.

PURPOSE: To investigate the current status of electrophysiological test use in ophthalmology. METHODS: We analyzed 1057 electrophysiological tests conducted at Kim's Eye Hospital from January 1 to December 31, 2018. The included tests were electroretinogram (full-field, multifocal, and pattern ERG), electrooculogram (EOG), and visual evoked potential (pattern and flash VEP). To investigate the distribution of use of subspecialties, it was divided by subspecialties (retina, glaucoma, oculoplastic surgery, pediatric ophthalmology, neuro-ophthalmology, cornea, and external diseases). RESULTS: The patients were aged 50.6 years on average and included 624 men and 433 women. Among the electrophysiological tests, VEP was the most common, with 567 cases (53.6%), followed by ERG with 311 cases (29.4%) and EOG with 98 cases (9.3%). Regarding the purpose of use, the objective of visual function evaluation was the highest at 56.3%, followed by the differential diagnosis of unknown causes (33.0%) and the confirmation of diagnoses (10.7%). Both VEP and ERG were used the most for visual function evaluation, and mfERG was most used for differential diagnosis of unknown etiology. Electrophysiological tests were most often used in the retina department, but VEPs were used in various fields such as neuro-ophthalmology, glaucoma, and oculoplastics. CONCLUSION: Electrophysiological tests are used to objectively evaluate visual function or discriminate diseases of unknown causes and are used in various departments. Electrophysiology testing is expected to be an additional test to assess visual function.

We investigated the characteristics of neovascular age-related macular degeneration (AMD) in which exudation predominantly occurs as a subretinal fluid (SRF) during anti-vascular endothelial growth factor (VEGF) treatment. A total of 509 treatment-naïve neovascular AMD patients treated with anti-VEGF for 24 months were retrospectively analyzed. The baseline characteristics to determine the odds of occurrence of SRF alone were evaluated using multivariate modeling. SRF was the sole manifestation of lesion activity in 209 (40.9%) eyes during follow-up. The visual outcome of eyes with only SRF occurrence during follow-up was comparable to that of eyes without exudative recurrence. In addition, the incidence of macular atrophy was significantly lower in eyes with only SRF occurrence (9.6%, 20 of 208 eyes) than in eyes without exudative recurrence (16.7%, 9 of 54 eyes, P = 0.018). Multivariate analysis revealed that better best-corrected visual acuity (BCVA) at baseline (odds ratio [OR], 0.306; P = 0.001), presence of SRF alone at baseline (OR, 5.256; P < 0.001), lower pigment epithelial detachment (PED) height (less than 100 µm; OR, 4.113; P = 0.025), and aneurysmal type 1 macular neovascularization (MNV) (OR, 2.594; P = 0.002) were associated with an increased likelihood of SRF occurrence during follow-up. In conclusion, the eyes with only SRF occurrence during anti-VEGF treatment showed more favorable visual outcomes and a lower incidence of macular atrophy. The baseline characteristics, including better baseline BCVA, presence of SRF alone at baseline, lower PED height, and MNV subtype, might influence the predominant development of SRF during anti-VEGF treatment.

PRCIS: Circumpapillary retinal nerve fiber layer (RNFL) thickness change induced by optical coherence tomography (OCT) scan circle location displacement was not completely compensated despite the use of Guided Progression Analysis (GPA), especially when the "R1" registration method was applied. PURPOSE: The purpose of this study was to evaluate the effect of inconsistent OCT scan location on glaucoma progression detection using GPA. METHODS: Eighty-four glaucomatous eyes with at least 4 serial OCT tests were included. To evaluate the ability of OCT GPA to adjust the OCT scan location, an analysis was performed without manipulation (control set), and after the OCT scan of the latest test was intentionally moved inferotemporally (test set). The eyes were classified into the adjustment and nonadjustment groups based on the superior or inferior quadrant RNFL thickness agreement between the control and test sets. RESULTS: When the OCT GPA parameters between the control and test sets were compared, the test set showed a greater superior RNFL thickness and lesser inferior RNFL thickness compared with the control set (P<0.05). The eyes in the nonadjustment group (n=21, 25%) had a lower chance of applying the eye-tracking function (P=0.003) and a higher frequency of the "R1" registration method of OCT GPA (P<0.001) than the adjustment group (n=63, 75%); all eyes with the "R1" method were in the nonadjustment group and all eyes with the "R2" method were in the adjustment group. CONCLUSIONS: Inconsistent OCT scan location induced changes in RNFL thickness that were not completely compensated despite the use of OCT GPA, especially when the "R1" registration method was applied. These findings indicates a potential for misidentified glaucoma progression.
