Characteristics of Korean medical care utilization in patients with traffic injury: Analysis of 3 hospital electronic health record databases.

This retrospective study aimed to identify the characteristics of Korean medical care utilization in patients with traffic injury (TI) and to explore the clinical effectiveness of Korean medical interventions for TI through a multicenter chart review. This multicenter, retrospective registry study gathered electronic health records from 3 hospitals between January 1, 2018 and December 31, 2021. Data included treatment dates, demographic information, the Korean Standard Classification of Diseases codes, collision data, Korean medicine treatment modalities, and treatment outcomes. In total, 384 patients (182 inpatients and 202 outpatients) were included in the analysis. Patients were categorized into acute (207 patients, 53.9%), subacute (77 patients, 20.1%), and chronic (100 patients, 26.0%) phases based on the period until the visit. The most frequent Korean Standard Classification of Diseases code was "sprain and strain of cervical spine (S13.4)." All patients, except one, received Korean physiotherapy, followed by acupuncture and cupping. Comparative intragroup analysis revealed significant pain reduction in patients treated with the combination of Chuna manual therapy, herbal medicine, and pharmacopuncture and those treated with pharmacopuncture and herbal medicine only. This study highlights the characteristics of patients with TI visiting medical institutions providing Korean medicine and describes the effectiveness of Korean medicine interventions. Further comprehensive analysis with more data is necessary for future research.

Toxicology and safety study of L-tryptophan and its impurities for use in swine.

L-tryptophan, an essential amino acid for physiological processes, metabolism, development, and growth of organisms, is widely utilized in animal nutrition and human health as a feed additive and nutritional supplement, respectively. Despite its known benefits, safety concerns have arisen due to an eosinophilia-myalgia syndrome (EMS) outbreak linked to L-tryptophan consumed by humans. Extensive research has established that the EMS outbreak was caused by an L-tryptophan product that contained certain impurities. Therefore, safety validations are imperative to endorse the use of L-tryptophan as a supplement or a feed additive. This study was conducted in tertiary hybrid [(Landrace × Yorkshire) × Duroc] pigs to assess general toxicity and potential risks for EMS-related symptoms associated with L-tryptophan used as a feed additive. Our investigation elucidated the relationship between L-tryptophan and EMS in swine. No mortalities or clinical signs were observed in any animals during the administration period, and the test substance did not induce toxic effects. Hematological analysis and histopathological examination revealed no changes in EMS-related parameters, such as eosinophil counts, lung lesions, skin lesions, or muscle atrophy. Furthermore, no test substance-related changes occurred in other general toxicological parameters. Through analyzing the tissues and organs of swine, most of the L-tryptophan impurities that may cause EMS were not retained. Based on these findings, we concluded that incorporating L-tryptophan and its impurities into the diet does not induce EMS in swine. Consequently, L-tryptophan may be used as a feed additive throughout all growth stages of swine without safety concerns.

Survey on the current usage of ultrasound-guided procedures in Korean Medicine Clinics and Hospitals.

Ultrasound-guidance is applied during the administration of Korean medicine (KM) interventions to improve the safety and effectiveness of the interventions. Although many case series and reports on the use of ultrasound-guided KM interventions have been reported, no study has investigated the current use of ultrasound-guidance in clinical practice by doctors of Korean medicine (KMDs). An online survey was conducted with questions examining the status of ultrasound-guidance usage among KMDs practicing in various KM clinical settings. Survey responses from 335 KMDs were collected. Ultrasound started to be widely used in the clinical practice of KM since 2022. The primary objective of using ultrasound-guidance was "To improve the accuracy and efficacy" by 54.6%. Ultrasound-guidance was most frequently applied for shoulder joint diseases, and pharmacopuncture was the most frequently used intervention (76.1% and 90.4%, respectively). The respondents reported that effectiveness could be enhanced the most in nerve entrapment syndromes and especially when used in shoulder joints. Over 90% of KMDs responded that the safety and efficacy of treatment, specialty, and patients' satisfaction were improved after adopting ultrasound-guidance. Moreover, 94.9% of KMDs agreed with the necessity for reimbursement of ultrasound-guidance in KM under national health insurance coverage. Most KMDs responded that they had positive perceptions regarding the clinical use of ultrasound-guidance in KM in terms of treatment effects, safety, and patient satisfaction, and the need for national health insurance coverage of the service. Our findings may provide practice-based evidence for conducting clinical studies.

Efficacy of acupuncture for whiplash injury: a systematic review and meta-analysis.

OBJECTIVES: This study aimed to establish clinical evidence for acupuncture by analysing data from trials that demonstrated the efficacy of acupuncture for whiplash-associated disorder (WAD) with the following research question: Is acupuncture treatment effective for symptom alleviation in patients with WAD compared with other usual care? DESIGN: A systematic review and meta-analysis. DATA SOURCES: PubMed, Ovid Medline, Embase, The Cochrane Library, China National Knowledge Infrastructure, ScienceOn, KMBASE, Korean Studies Information Service System, Korea Med, Oriental Medicine Advanced Searching Integrated System and Research Information Sharing Service were searched from their inception to 1 October 2023. ELIGIBILITY CRITERIA: We included randomised controlled trials (RCTs) using acupuncture on patients with WAD. The outcomes were the pain visual analogue scale (VAS) score or numerical rating scale score for neck pain, the range of motion (ROM) of the neck, the Neck Disability Index and safety. DATA EXTRACTION AND SYNTHESIS: Two independent researchers analysed and extracted data from the selected literatures. The risk of bias and the quality of evidence were assessed according to the Cochrane Handbook for Systematic Reviews of Interventions and the Grading of Recommendations Assessment, Development, and Evaluation method, respectively. RESULTS: A total of 525 patients with WAD from eight RCTs were included in this study. The meta-analysis revealed that the outcomes showed significant differences in the pain VAS score (standard mean difference (SMD): -0.57 (-0.86 to -0.28), p<0.001) and ROM-extension (SMD: 0.47 (0.05 to 0.89), p=0.03). The risk of bias assessment revealed that four studies published after 2012 (50%, 4 out of 8 studies) showed low bias in most domains. The pain VAS score was graded as having moderate certainty. CONCLUSION: Acupuncture may have clinical value in pain reduction and increasing the ROM for patients with WAD. High-quality RCTs must be conducted to confirm the efficacy of acupuncture in patients with WAD. TRIAL REGISTRATION NUMBER: PROSPERO CRD42021261595.

Toxicology and safety study of L-tryptophan and its impurities for use in broiler feed.

L-tryptophan has been utilized as a feed additive in animal nutrition to improve growth performance, as well as a dietary supplement to alleviate various emotional symptoms in humans. Despite its benefits, concerns regarding its safety arose following the outbreak of eosinophilia-myalgia syndrome (EMS) among individuals who consumed L-tryptophan. The causative material of EMS was determined to be not L-tryptophan itself, but rather L-tryptophan impurities resulting from a specific manufacturing process. To investigate the effect of L-tryptophan and its impurities on humans who consume meat products derived from animals that were fed L-tryptophan and its impurities, an animal study involving broiler chickens was conducted. The animals in test groups were fed diet containing 0.065%-0.073% of L-tryptophan for 27 days. This study aimed to observe the occurrence of toxicological or EMS-related symptoms and analyze the residues of L-tryptophan impurities in meat products. The results indicated that there was no evidence of adverse effects associated with the test substance in the investigated parameters. Furthermore, most of the consumed EMS-causing L-tryptophan impurities did not remain in the meat of broiler chickens. Thus, this study demonstrated the safety of L-tryptophan and some of its impurities as a feed additive.

Effectiveness and safety of scalp acupuncture for treating migraine: A systematic review and meta-analysis.

OBJECTIVE: Migraine is a prevalent and disabling neurological disorder affecting a significant proportion of the global population. Although medications are the primary treatment option, their efficacy remains unclear. Thus, alternative therapies such as scalp acupuncture have gained momentum; however, evidence for the effectiveness of scalp acupuncture remains insufficient. Therefore, this review provides evidence regarding the effectiveness and safety of scalp acupuncture for the treatment of migraines. DESIGN: PubMed, EMBASE, CENTRAL, Oriental Medicine Advanced Searching Integrated System, Korean Studies Information Service System, Korean Medical Database, NDSL, Citation Information by NII, and China National Knowledge Infrastructure were searched from their inception to September 2022 to identify randomised controlled trials (RCTs) without language restrictions. Data were collected and analysed independently by two reviewers. The RoB 2.0 tool was used to evaluate the risk of bias, and a meta-analysis was conducted using RevMan software (V5.4). SETTING: Eight RCTs including 874 patients were selected. RESULTS: Scalp acupuncture had a higher total effective rate (relative risk [RR]:1.24; 95% confidence interval [CI]:1.08-1.43; P < 0.01) than that of ordinary acupuncture. The headache index decreased significantly (standardised mean differences [SMD]:-1.27; 95% CI:-2.06 to -0.48; P < 0.01), and the total effective rate was higher (RR:1.20; 95% CI:1.06-1.37; P < 0.01) with scalp acupuncture than with medications. However, evidence supporting the effectiveness of scalp acupuncture was not robust. No adverse events were reported. CONCLUSION: Scalp acupuncture appears to be more effective than other treatments for migraines. However, their safety remains uncertain. PROSPERO REGISTRATION NUMBER: CRD42022348879.

Safety concerns regarding impurities in L-Tryptophan associated with eosinophilia myalgia syndrome.

L-tryptophan is one of the essential amino acids in humans and across the animal kingdom. It has been widely used as a feed additive for domestic animals and is also administered through dietary supplements in humans. Safety concerns have been raised however since a disease known as eosinophilia-myalgia syndrome (EMS) was reported to be related to L-tryptophan supplements. EMS is a rare condition characterized by inflammation in various organ systems including the muscles, skin, and lungs. Through several studies, it has been speculated that the six components generated during the process of L-tryptophan synthesis are related to the induction of EMS. In this review, we discuss the history of EMS and its controversial correlation with L-tryptophan use reported in several studies. Many in vitro and in vivo studies have been conducted to assess the putative correlation between impurities in L-tryptophan preparations and EMS, but no clear and convincing conclusions have been drawn so far.

Anti-obesity effect of Lythri herba water extracts in vitro and in vivo.

ETHNOPHARMACOLOGICAL RELEVANCE: Lythrum salicaria L., also called purple loosestrife, has traditionally been used as a medicinal plant to treat internal dysfunction, such as gastrointestinal disorders or hemorrhages. It contains numerous phytochemical compounds, including orientin, and has been reported to have anti-diarrheal, anti-inflammatory, antioxidant, and antimicrobial properties. AIM OF THE STUDY: The effects of Lythrum salicaria L. on obesity have not been explored. Therefore, we investigated the anti-obesity effects of Lythri Herba, the aerial part of this plant, in vitro and in vivo. MATERIALS AND METHODS: Using distilled water, Lythri Herba water extracts (LHWE) were prepared by extracting Lythri Herba at 100°Ï¹. The contents of orientin in LHWE were identified using High Performance Liquid Chromatography (HPLC) analysis. To evaluate the anti-obesity effect of LHWE, 3T3-L1 adipocytes and a high-fat diet (HFD)-fed mice were used. Oil-red O staining was performed to examine the anti-adipogenic effects of LHWE in vitro. The histological changes in epididymal white adipose tissue (epiWAT) by LHWE were examined using hematoxylin and eosin staining. Serum leptin levels were measured by enzyme-linked immunosorbent assay. Specific quantification kits measured total cholesterol and triglyceride levels in the serum. The relative fold induction of protein and mRNA was determined using western blot and Quantitative real-time Polymerase Chain Reaction analysis, respectively. RESULTS: HPLC analysis demonstrated the presence of orientin in LHWE. LHWE treatment markedly reduced lipid accumulation in differentiated 3T3-L1 adipocytes. LHWE administration also conferred resistance to HFD-induced weight gain in mice and reduced epiWAT mass. Mechanistically, LHWE significantly decreased lipogenesis by downregulating lipoprotein lipase (LPL), glucose-6-phosphate dehydrogenase, ATP-citrate lyase, fatty acid synthase, stearoyl-CoA desaturase 1, sterol regulatory element binding transcription factor 1, and carbohydrate response element binding protein expression and increased the expression of genes involved in fatty acid oxidation (FAO), peroxisome proliferator-activated receptor α and carnitine palmitoyltransferase 1 in 3T3-L1 adipocytes and epiWAT. Furthermore, LHWE significantly up-regulated the phosphorylation of AMP-activated protein kinase in 3T3-L1 adipocytes and epiWAT. CONCLUSION: LHWE decreases white adipogenesis in vitro and HFD-induced weight gain in vivo, which is associated with reduced lipogenesis and enhanced FAO.

Simultaneous determination of L-tryptophan impurities in meat products.

L-tryptophan has been used as a feed additive for swine and poultry and as a nutrient supplement for humans. However, some impurities in L-tryptophan have been reported as causative components of eosinophilia-myalgia syndrome. Therefore, from a safety perspective, it is important to analyze meat samples for these impurities. This study aims to develop an analytical method for the simultaneous detection of L-tryptophan impurities in meat products using LC-MS/MS. Among the various impurities, detection methods for (S)-2-amino-3-(5-hydroxy-1H-indol-3-yl)propanoic acid (5-hydroxytryptophan) (HTP), 1-methyl-1,2,3,4-tetrahydro-ß-carboline-3-carboxylic acid (MTCA), 3a-hydroxy-1,2,3,3a,8,8a-hexahydropyrrolo-[2,3-b]-indole-2-carboxylic acid (PIC), and 1,1'-ethylidenebistryptophan (EBT) and 2-(3-indoylmethyl)-L-tryptophan (IMT) were developed. The developed method allowed simultaneous determination of these four impurities in 5 min. No interferences from the matrix were observed, and the method showed good sensitivity to each analyte. The method detection limit and limit of quantification in meat matrices were below 11.2 and 35.7 µg/kg, respectively.

Safety evaluation of dried L-tryptophan fermentation product in Sprague-Dawley rats.

The subchronic toxicity of oral L-tryptophan produced by fermentation with metabolically engineered Corynebacterium glutamicum was evaluated in Sprague-Dawley rats. Doses of 0, 500, 1000, and 2000 mg/kg/day were administered to groups of 10 male and 10 female rats for 90 days. For the groups administered 0 and 2000 mg/kg/day, an additional 5 male and 5 female rats were tested as a recovery group. No adverse effects associated with the test substance were observed in all rats during the 90-day administration of the product, irrespective of dose, and at 4 weeks of recovery at dosages of 0 and 2000 mg/kg/day. Furthermore, histochemical and immunohistochemical analyses for L-tryptophan-associated eosinophilia-myalgia syndrome (EMS) did not reveal significant changes in both sexes of groups administered 0 or 2000 mg/kg/day. Based on these results, it could be concluded that there were no significant adverse effects related to the test substance in all animals; therefore, dried L-tryptophan fermentation product can be used as feed additive material.

Efficacy of scalp acupuncture for migraine: A protocol for systematic review and meta-analysis.

INTRODUCTION: Migraine is a disorder that is prevalent worldwide. However, there is still no clear and effective treatment for migraine. Recently, acupuncture as a treatment has been attracting attention and studies have shown the value of scalp acupuncture. Therefore, this protocol for a systematic review and meta-analysis was created to assess the evidence of effectiveness and safety of scalp acupuncture in the treatment of migraine. METHODS: All published randomized controlled trials (RCTs) in the following databases will be searched from their inception to September 2022: PubMed, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), OASIS, Korean Studies Information Service System (KISS), Korean Medical Database and NDSL, CiNii (Citation Information by NII), and the China National Knowledge Infrastructure (CNKI), without language restrictions. The data collection and analysis will be conducted independently by two reviewers. The Cochrane Collaboration tool will be used to evaluate the risk of bias by evaluating the available studies. A meta-analysis will be conducted using RevMan V.5.4 software. RESULTS: The purpose of the proposed systemic review is to systematically assess the effectiveness and safety of scalp acupuncture for the treatment of migraine. CONCLUSIONS: To sum up, this review will assess the effectiveness and safety of scalp acupuncture for the treatment of migraine. The results of this review are expected to provide new guidelines for the treatment of migraine. ETHICS AND DISSEMINATION: The review and meta-analysis will not require ethical approval because personal information from individuals will not be involved. The results will be published in a peer-reviewed journal.

Scalp acupuncture for stroke: A protocol for an overview of systematic reviews and meta-analysis.

BACKGROUND: Scalp acupuncture (SA) is a new acupuncture method that connects head acupoints and aculines, and many systematic reviews (SRs) have been published on its use against neuropsychiatric diseases. However, no overview of SRs on the effectiveness of SA in stroke recovery has been conducted. Therefore, our overview aims to evaluate the methodological bias and reliability of the conclusions of SRs regarding SA for stroke recovery and help clinical decision-makers translate this research into clinical policy and practice. METHODS: We will consider SRs and meta-analyses of randomized controlled trials to evaluate the effects of SA on stroke recovery. Two reviewers will identify relevant studies, extract data information, and assess the methodological quality using the Assessment of Multiple Systematic Reviews-2 tool. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses report checklist will also be included in the study to assess the quality of the reports. We will use evaluations of the Grading of Recommendations Assessment, Development and Evaluation of the authors of the included SRs. The Risk of Bias in Systematic Review tool will be used to assess the risk of bias of SRs. The screening of SRs, eligibility evaluation, data extraction, methodological quality, and quality of evidence will be conducted by independent reviewers in pairs. The outcomes of interest include the Modified Edinburgh-Scandinavian Stroke Scale, Ability of Daily Living, Functional Independence Measure, Barthel index, Fugl-Meyer assessment, clinical effective rate, and adverse events. Data will be extracted using predefined forms designed to summarize the important characteristics of each review. The evidence will be a descriptive synthesis of the type and content of the intervention and the results reported. RESULTS: The results will be published in a peer-reviewed journal. CONCLUSIONS: We expect to organize evidence from multiple SRs on the effectiveness of SA for stroke recovery and synthesize the findings in an accessible and useful documentation.

Comparative Effectiveness and Safety of Concomitant Treatment with Chuna Manual Therapy and Usual Care for Whiplash Injuries: A Multicenter Randomized Controlled Trial.

OBJECTIVES: We aimed to compare the effectiveness and safety of Chuna manual therapy combined with usual care to those of usual care alone for treating whiplash injuries. DESIGN: A two-arm, parallel, assessor-blinded, multicenter pragmatic randomized clinical trial. SETTING: Three hospitals in Korea. PARTICIPANTS: Overall, 132 participants between 19 and 70 years of age, involved in traffic accidents and treated at three hospitals in Korea, >2 but <13 weeks prior to enrollment, with neck pain consistent with whiplash-associated disorder grades I and II and a numeric rating scale score ≥5 were included. INTERVENTIONS: Participants were equally and randomly allocated to the Chuna manual therapy and usual care (n = 66) or usual care (n = 66) groups and underwent corresponding treatment for three weeks. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the number of days to achieve a 50% pain reduction. Secondary outcomes included areas under the 50% numeric rating scale reduction curve: pain, disability, quality of life, and safety. RESULTS: The Chuna manual therapy + usual care group (23.31 ± 21.36 days; p = 0.01) required significantly fewer days to achieve 50% pain reduction compared to the usual care group (50.41 ± 48.32 days; p = 0.01). Regarding pain severity, functional index, and quality of life index, Chuna manual therapy and usual care were more effective than usual care alone. Safety was acceptable in both groups. CONCLUSIONS: In patients with subacute whiplash injury, Chuna manual therapy showed a rapid rate of recovery, high effectiveness, and safety.

Structure of benzene from mass-correlated rotational Raman spectroscopy.

We present high resolution rotational Raman spectra and derived geometry parameters for benzene. Rotational Raman spectra with sub-5 MHz resolution were obtained via high-resolution mass-correlated rotational alignment spectroscopy. Isotopologue spectra for C6H6, 13C-C5H6, C6D6, and 13C-C5D6 were distinguished through their correlated mass information. Spectra for 13C6H6 were obtained with lower resolution. Equilibrium and effective bond lengths were estimated from measured inertial moments, based on explicit assumptions and approximations. We discuss the origin of significant bias in previously published geometry parameters and the possibility to derive H,D isotope-specific bond lengths from purely experimental data.

Mass-Correlated High-Resolution Spectra and the Structure of Benzene.

Mass-correlated rotational alignment spectroscopy resolved the rotational Raman spectra for 5 benzene isotopologues with unprecedented resolution. 13-C isotopologues were characterized at natural abundance. Fitted rotational constants allowed the analysis of effective and equilibrium bond lengths for benzene with sub-mÅ uncertainties. We found that previously reported experimental structures were wrong by multiple mÅ, due to unrecognized H/D isotope effects. Our results also refute recent experimental and theoretical literature claims of identical effective C-H and C-D bond lengths in benzene and reveal an isotope effect similar to that in other small molecules.

Adaptation and Dissemination of Korean Medicine Clinical Practice Guidelines for Traffic Injuries.

In South Korea, car insurance that includes medical coverage of traditional Korean medicine (TKM) has increased exponentially. Clinical practice guidelines (CPG) for traffic injuries were established in 2016. We aimed to revise and update de novo CPG and distribute the adapted CPG to TKM practitioners and patients. Clinical key questions from previous CPG were identified and updated regarding the grade of recommendation and level of evidence using additional evidence from the literature obtained through a systematic search and the use of the Grading of Recommendations Assessment, Development, and Evaluation methodology. The dissemination and implementation of the updated CPG were conducted at the CPG Center of Korean Medicine. Ultimately, 25 recommendations based on 13 clinical key questions were developed: 2 for diagnosis, 22 for TKM treatments, and 1 for prognosis. After recognition by professional societies and certification by the CPG Center of Korean Medicine, leaflets, card news, and infographics for TKM doctors in South Korea were produced and distributed. These are the only TKM CPG for patients who have experienced traffic injuries. They are expected to contribute to standardized and evidence-based treatment using TKM and similar interventions. Moreover, disseminating the adapted CPG will promote treatment reliability and strengthen insurance coverage.

Comparison between Atomoxetine and OROS Methylphenidate as an Adjunctive to SSRIs in Attention-deficit/Hyperactivity Disorder Adults with Comorbid Partially Responsive Major Depressive Disorder: A Head-to-head, 12-week, Randomized, Rater-blinded Clinical Trial.

OBJECTIVE: This study aimed to compare the efficacy and safety of atomoxetine (ATX) and OROS methylphenidate (MPH) as adjunctive to selective serotonin reuptake inhibitors (SSRIs) in adults with attention-deficit hyperactivity disorder (ADHD) with comorbid partially responsive major depressive disorder (MDD). METHODS: Sixty Korean adults with ADHD and comorbid partially responsive MDD were recruited in a 12-week, randomized, rater-blinded, active-controlled trial and were evenly randomized to ATX or OROS MPH treatment. RESULTS: Depressive symptoms measured using the Hamilton Depression Rating Scale and Clinically Useful Depression Outcome Scale, and ADHD symptoms measured using the Adult ADHD Self-Report Scale, as well as the Clinical Global Impression-Severity, Clinical Global Impression-Improvement, and the Sheehan Disability Scale scores were significantly improved in both groups during the 12 weeks of treatment. The changes in all outcome measures during the 12-week treatment were not significantly different between the two groups (all p > 0.05). No serious adverse events were reported and there were no significant differences in systolic and diastolic blood pressure, pulse rate, weight, or body mass index between the ATX and MPH groups. CONCLUSION: Our findings suggest that ATX and MPH can be used as adjunctive treatments in adults with ADHD and comorbid partially responsive MDD. The efficacy and tolerability of ATX and MPH in adults with ADHD did not differ significantly. Further studies should be conducted to draw a definitive conclusion.

Electrophysiological Changes Related to Childhood Trauma in Patients with Major Depressive Disorder: An Event-related Potential Study.

OBJECTIVE: Childhood trauma is the most important environmental factor for several psychiatric disorders. Depressed patients with childhood trauma appear to have severe symptoms that frequently recur. This study investigated whether depressed patients with childhood trauma showed attenuated Nogo event-related potentials (ERPs) and source activity during response-inhibition tasks. METHODS: Forty-four patients patients with major depressive disorder (MDD) were instructed to perform a Go/Nogo task during electroencephalography. Sensors and source activities of N2 and P3 of the Nogo ERPs were analyzed. The participants' clinical symptoms were assessed using the Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory, State-Trait Anxiety Inventory, Barratt Impulsivity Scale, and Affective Lability Scale. The participants were divided into two groups (low and high), based on their total CTQ scores. RESULTS: MDD subjects with high CTQ scores showed significantly decreased Nogo P3 amplitudes at the frontal, frontocentral, central, and parietal electrodes than those with low CTQ scores (all p < 0.01). In Nogo P3, the source activities of the right cuneus, right posterior cingulate cortex, right precuneus, left supramarginal gyrus, and left lingual gyrus were significantly lower in the high CTQ group than in the low one (all p < 0.01). There were significant negative correlations between the total CTQ scores and the Nogo P3 amplitudes in the frontocentral (p = 0.03) and parietal regions (p = 0.02), which showed lower source activity in the Nogo P3 condition. CONCLUSION: Depressed patients with severe childhood trauma showed different Nogo-ERP characteristics, which might reflect inhibitory failure and dysfunction in related brain regions.

Efficacy of acupuncture for whiplash injury: A protocol for systematic review and meta-analysis.

BACKGROUND: Studies in both Eastern & Western countries such as the United States and Europe have evaluated the efficacy of acupuncture for whiplash injury or whiplash-associated disorder (WAD). However, no systematic reviews on the effectiveness of acupuncture on WAD have been conducted since 2014. Therefore, we are planning an updated systematic review of studies published since 2014 to overcome the limitations of existing evidence. METHODS: Literature will be identified from searches of relevant databases, including international databases such as PubMed, Ovid-Medline, Embase, The Cochrane Library, and China National Knowledge Infrastructure and Korean databases such as Korea Med, Korean Studies Information Service System, Oriental Medicine Advanced Searching Integrated System, and National Digital Science Library. Only randomized controlled trials using acupuncture or electro-acupuncture for whiplash injury will be included. The primary outcomes will be the visual analog scale or numerical rating scale of the neck pain, while the secondary outcome is the range of motion of the neck. The risk of bias for individual papers will be assessed by two independent investigators using the Cochrane "Risk of Bias" assessment tool. DISSEMINATION: We plan to report the results of the study in a peer-reviewed journal after completing the research. In addition, we expect this study to provide invaluable information to clinicians treating patients with WAD with acupuncture or electro-acupuncture. TRIAL REGISTRATION NUMBER: PROSPERO 2021: CRD42021261595. Registered on 18 July 2021. https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=261595.

Cost-Effectiveness of Chuna Manual Therapy and Usual Care, Compared with Usual Care Only for People with Neck Pain following Traffic Accidents: A Multicenter Randomized Controlled Trial.

This is the first cost-effectiveness analysis of Chuna manual therapy (CMT) plus usual Korean traditional medicine for traffic accident victims using a randomized controlled trial. A total of 132 participants were equally allocated to the intervention group receiving 6-11 sessions of CMT plus usual Korean traditional medicine care for three weeks or usual care including acupuncture, cupping, herbal medicine, moxibustion, and traditional physiotherapy at three hospitals. At 12 weeks, from a healthcare perspective, the intervention group had significantly higher costs (mean (SD), $778 (435) vs. $618 (318); difference, $160; 95% CI, $15 to $289; p = 0.005). From a societal perspective, total costs were insignificantly lower in the intervention group (mean (SD), $1077 (1081) vs. $1146 (1485); difference, $-69; 95% CI, $-568 to $377; p = 0.761). The intervention group dominated, with significantly higher QALYs gained at lower overall cost with a 72% chance of being cost-effective. From a societal perspective, the intervention was cost-saving for individuals who had neck pain after car accidents, although it was not cost-effective from the healthcare perspective ($40,038 per QALY gained). Findings support use of CMT as an integrated care treatment for whiplash from a societal perspective. Further studies with larger sample sizes are needed to determine cost-effectiveness in other cultural contexts.
