Molecular and Genomic Analysis of the Virulence Factors and Potential Transmission of Hybrid Enteropathogenic and Enterotoxigenic Escherichia coli (EPEC/ETEC) Strains Isolated in South Korea.

Hybrid strains Escherichia coli acquires genetic characteristics from multiple pathotypes and is speculated to be more virulent; however, understanding their pathogenicity is elusive. Here, we performed genome-based characterization of the hybrid of enteropathogenic (EPEC) and enterotoxigenic E. coli (ETEC), the strains that cause diarrhea and mortality in children. The virulence genes in the strains isolated from different sources in the South Korea were identified, and their phylogenetic positions were analyzed. The EPEC/ETEC hybrid strains harbored eae and est encoding E. coli attaching and effacing lesions and heat-stable enterotoxins of EPEC and ETEC, respectively. Genome-wide phylogeny revealed that all hybrids (n = 6) were closely related to EPEC strains, implying the potential acquisition of ETEC virulence genes during ETEC/EPEC hybrid emergence. The hybrids represented diverse serotypes (O153:H19 (n = 3), O49:H10 (n = 2), and O71:H19 (n = 1)) and sequence types (ST546, n = 4; ST785, n = 2). Furthermore, heat-stable toxin-encoding plasmids possessing estA and various other virulence genes and transporters, including nleH2, hlyA, hlyB, hlyC, hlyD, espC, espP, phage endopeptidase Rz, and phage holin, were identified. These findings provide insights into understanding the pathogenicity of EPEC/ETEC hybrid strains and may aid in comparative studies, virulence characterization, and understanding evolutionary biology.

Chromatographic Method for Monitoring of Pesticide Residues and Risk Assessment for Herbal Decoctions Used in Traditional Korean Medicine Clinics.

The presence of pesticide residues in herbs and the herbal products derived from them raises serious health concerns. This study was conducted to investigate the residual pesticide concentrations and assess potential human health risks from herbal medicines used in traditional Korean medicine clinics. A total of 40 samples of herbal decoctions were collected from 10 external herbal dispensaries. The pesticide residues were analyzed by the multiresidue method for 320 different pesticides using liquid chromatography tandem mass spectrometry (LC-MS/MS) and gas chromatography tandem mass spectrometry (GC-MS/MS). As a result of the monitoring, carbendazim was detected at 0.01 and 0.03 µg/g in eight samples and no pesticide was detected in the other herbal decoctions. Carbendazim was set for each individual item as less than 0.05 µg/g in Paeoniae radix, less than 0.05 µg/g in Cassiae semen, less than 2.0 µg/g in Lycii fructus, and less than 10 µg/g in Schisandrae fructus (dried). Therefore, the results of this study suggested that the detected pesticide residues in herbal decoctions could not be considered as posing a serious health risk.

Association between osteoarthritis and unmet medical needs in Korea: limitations in activities as a mediator.

BACKGROUND: The role of limitations in activities in relation to unmet needs is not clarified. This study aimed to analyze the effects of osteoarthritis on unmet medical needs and the mediating effects of limitations in activities. METHODS: A total number of 10,129 population aged ≥50 years were included using data from the Korean National Health and Nutrition Examination Survey from January 2010 to December 2013. Osteoarthritis was defined as Kellgren-Lawrence grade ≥ 2 in the knee, hip, and lumbar spine joints with pain reported to have lasted for ≥3 months. Limitations in activities were defined as currently experiencing restricted daily and social activities. Unmet medical needs were analyzed after they were further divided into availability, accessibility, and acceptability. Causal mediation analysis was employed to analyze mediating effects. RESULTS: The osteoarthritis group had a higher odds ratio (OR: 1.65; 95% confidence interval [CI], 1.56-1.75) for the total effects of osteoarthritis on unmet medical needs than the non-osteoarthritis group. Furthermore, the OR for the indirect effects mediated by limitations in activities was higher in the osteoarthritis group (OR: 1.07; 95% CI, 1.05-1.08), indicating that 13.2% of the total effect was mediated. When the analysis was further classified according to cause, the mediating effect of limitations in activities was the strongest at 23.9% for unmet medical needs due to lack of transportation accessibility. CONCLUSIONS: Osteoarthritis exerts significant effects on the experience of unmet medical needs, and limitations in activities mediate such experiences of unmet medical needs in osteoarthritis patients.

Upgrading of Quality Control for Herbal Medicine Use in South Korea by Introducing an Accreditation System: a brief report.

Objectives: This study aimed to present a government-led accreditation system for upgrading the quality control of herbal medicine by introducing the process and evaluation standard of external herbal dispensaries (EHDs) of traditional Korean medicine (TKM) clinics in South Korea 2018 to refer to other countries where herbal medicine were used similarly in Korea. Development Process: We organized an EHD accreditation committee for the establishment of an accreditation system. The committee consisted of 9 experts an official of the Ministry of Health and Welfare (MoHW), a professor expert of TKM, a good manufacturing practice expert, a hazard analysis and critical control point expert, and an accreditation system expert. After 3 meetings, a draft of the evaluation standard and evaluation system was established in 2017. Based on the draft, a pilot test was conducted to determine the applicability of the evaluation standards in 2017. Two additional meeting was held to confirm the accreditation standards and was finalized in 2018. Results: The evaluation standard for EHDs was developed. In the case of herbal medicine EHDs, the evaluation standard consisted of 9 evaluation categories, 25 evaluation parts, and 81 evaluation items were developed. The results of the evaluation of the pilot tests are as follows, and the results show that there is a deviation between the EHDs. Conclusion: As a world's first, Korea MoHW successfully launched the accreditation system for upgrading the quality control system of herbal medicine not approved by Korea's Ministry of Food and Drug Safety in 2018. Our report hope to provide a good reference to other countries where having similar herbal medicine system in South Korea hoping to make better quality control of herbal medicines.

Bee venom acupuncture and herbal medicine for hand eczema: Two case reports and an in vivo study.

INTRODUCTION: Eczema and contact dermatitis are relatively common, non-life-threatening disease, but can reduce the patient's quality-of-life when it becomes chronic. This study describes two cases of bee venom acupuncture (BVA) and herbal medicine (San Wu Huangqin decoction; SWH) co-treatment for hand eczema and contact dermatitis, then confirms the effect of the combination therapy in an in vivo model of eczema. CASE PRESENTATION: A 56-year-old female (case 1) and a 33-year-old male (case 2) presented to the clinic with symptoms of itching and erythema (case 1), and scaliness (case 2) on both hands. Both were diagnosed with hand eczema and contact dermatitis based on examination of the erythema and scaliness. They were treated with BVA and SWH for three months. The lesions were healed and had not recurred after 1 and 3 years of follow-up. A mouse study was conducted by repeated application of 2,4-dinitrochlorobenzene (DNCB) to induce eczema-like contact dermatitis in Balb/c mice. In a DNCB-induced eczema-like contact dermatitis model, BVA and SWH co-administration synergistically improved clinical symptoms seen in eczema. Also, they improved histological changes of the skin, suppressed immune cell infiltration, and decreased inflammatory cytokines and immunoglobulin E in the serum. CONCLUSION: This study suggests BVA and SWH could be an alternative treatment for eczema and contact dermatitis.

A Survey of Utilization and Satisfaction of Korean Subfertility Treatment among Korean Women.

Low fertility is a critical social problem worldwide, and infertility has a prevalence of 15%. This cross-sectional study aimed to understand the factors affecting the usage and satisfaction of Korean medicine (KM) in subfertile women. An online survey was conducted from 3 November to 8 November 2021. The survey collected basic information, KM treatment experience, and satisfaction from women who experienced poor pregnancy. The t-test and chi-square test (χ2-test) were used to determine the overall characteristics of the subjects and factors affecting the utilization and satisfaction of KM treatment. Of the total of 29,465 people, 4922 read the survey email, and 601 responded. After excluding 51 respondents with questionable response patterns, 550 respondents were included in the final analysis. Of these, 43.1% (n = 237) had experience with conventional treatment, and 16.5% (n = 91) had received KM treatment. The group that received both KM treatment and CM treatment (n = 59, 24.9%) was significantly more prevalent than the group that received KM treatment alone (n = 32, 10.2%) (p = 0.00). Women who had given birth more than once or held a master's degree were significantly more willing to participate in the 'KM Support Project for Subfertility' program. Our findings suggest that subfertile patients prefer integrated treatment that combines KM and CM treatments. Further studies are needed to assess the status of integrative medicine treatment, satisfaction with each KM intervention, factors for low satisfaction, and patient requirements.

Acupuncture Treatment for Hip Pain: A Systematic Review and Meta-Analysis.

Acupuncture treatment (AT) is an effective treatment for pain relief; however, there are few systematic reviews that have reported on the effectiveness of AT for hip pain. This systematic review aimed to evaluate the efficacy and safety of AT of hip pain. We searched eight databases for randomised controlled trials (RCTs) evaluating the effect of AT on hip pain until August 2022. Twelve RCTs (806 patients) were included: two reported a significant effect of AT compared with that of conventional medicine (CM) alone for hip pain; two reported significant effects of AT + CM compared with that of CM alone in terms of Visual Analogue Scale (VAS); two reported a significant effect of AT + CM compared with that of Sham AT + CM in terms of anaesthetic dosage; two reported a significant effect of AT + CM compared with that of Sham AT + CM in terms of the side effects associated with analgesic use; one study reported a significant effect of AT compared to that of no-treatment. No serious adverse events were reported. Our findings demonstrate the potential of AT in managing hip pain. Given the low quality and small sample sizes of the studies, the evidence supporting AT for hip pain management was weak. Further clinical trials and systematic reviews are required. The protocol of the current study was registered in the PROSPERO International prospective register of systematic reviews (CRD42017079586).

Acupuncture Treatment for Emotional Problems in Women with Infertility: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to evaluate the efficacy and safety of acupuncture in treating emotional problems in women with infertility. We searched for randomized controlled trials using acupuncture treatment for emotional problems in women with infertility using 11 databases from their inception to 30 June 2023. The control intervention included no treatment, sham acupuncture treatment, and conventional treatment. The primary outcome was emotion-related rating scales, and the secondary outcomes were total effectiveness rate, quality of life, clinical pregnancy rate, and adverse events. Twelve randomized controlled trials involving 1930 participants were included. A meta-analysis of these studies indicated that, as compared to the control treatment, acupuncture significantly improved the State-Trait Anxiety Inventory, Self-rating Anxiety Scale, Amsterdam Preoperative Anxiety and Information Scale, and Self-rating Depression Scale scores, which were the primary emotion-related outcomes. Furthermore, the meta-analysis demonstrated that acupuncture treatment had a significant effect on the clinical pregnancy rate, which was the secondary outcome. No adverse events were reported in any of the studies. Our findings demonstrate the potential of acupuncture for treating emotional problems in women with infertility. However, well-designed and high-quality randomized clinical trials are required to confirm the effectiveness and safety of acupuncture treatment. The protocol of the current study was registered in PROSPERO (registration number: CRD42020166119).

Herbal Medicine for Postpartum Pain: A Systematic Review of Puerperal Wind Syndrome (Sanhupung).

Mothers in the postpartum period often experience musculoskeletal disorders and pain, impacting their ability to care for themselves and their infants. Conventional treatments have limitations, prompting interest in alternative options like herbal medicine. This systematic review aimed to confirm the effectiveness and safety of herbal medicine treatment to improve maternal health in patients with postpartum pain (puerperal wind syndrome). We searched eight electronic databases for randomized controlled trials (RCTs) to evaluate the effects of herbal medicines on puerperal wind syndrome. Nine RCTs, including 652 patients, were selected. Following a meta-analysis of RCTs, both herbal medicine and combination treatments improved the visual analog scale scores, total effective rate, scores of Traditional Chinese Medicine syndromes, Oswestry Disability Index, and quality of life in patients with role-emotional puerperal wind syndrome. All adverse events were minor, and the incidence rate was not high compared with that of the control group. In conclusion, herbal medicine supports the improvement in pain, other systemic symptoms, and the quality of life of patients with puerperal wind syndrome. Moreover, no serious side effects were observed; therefore, herbal medicines appear to be safe. It can be the preferred treatment option for puerperal wind syndrome, which is currently managed symptomatically.

Bee Venom Acupuncture for Neck Pain: A Review of the Korean Literature.

Bee venom is a natural toxin that is effective in treating various types of pain. The purpose of this paper was to review all the features of clinical studies conducted on bee venom acupuncture (BVA) for the treatment of neck pain in Korean publications. Six Korean databases and 16 Korean journals were searched in August 2022 for clinical studies on BVA for neck pain. We identified 24 trials that met our inclusion criteria, of which 316 patients with neck pain were treated with BVA. The most common diagnosis in the patients with neck pain was herniated intervertebral discs (HIVDs) of the cervical spine (C-spine) (29.2%), and the concentration and dosage per session were 0.05-0.5 mg/mL and 0.1-1.5 mL, respectively. The visual analog scale was most often measured for neck pain severity (62.5%), and all clinical research reported improvements in 16 outcome measures. This study shows that BVA could be recommended for the treatment of neck pain, especially HIVD of the C-spine; however, the adverse effects of BVA must be examined in future studies.

Genome-Based Characterization of Hybrid Shiga Toxin-Producing and Enterotoxigenic Escherichia coli (STEC/ETEC) Strains Isolated in South Korea, 2016-2020.

The global emergence of hybrid diarrheagenic E. coli strains incorporating genetic markers from different pathotypes is a public health concern. Hybrids of Shiga toxin-producing and enterotoxigenic E. coli (STEC/ETEC) are associated with diarrhea and hemolytic uremic syndrome (HUS) in humans. In this study, we identified and characterized STEC/ETEC hybrid strains isolated from livestock feces (cattle and pigs) and animal food sources (beef, pork, and meat patties) in South Korea between 2016 and 2020. The strains were positive for genes from STEC and ETEC, such as stx (encodes Shiga toxins, Stxs) and est (encodes heat-stable enterotoxins, ST), respectively. The strains belong to diverse serogroups (O100, O168, O8, O155, O2, O141, O148, and O174) and sequence types (ST446, ST1021, ST21, ST74, ST785, ST670, ST1780, ST1782, ST10, and ST726). Genome-wide phylogenetic analysis revealed that these hybrids were closely related to certain ETEC and STEC strains, implying the potential acquisition of Stx-phage and/or ETEC virulence genes during the emergence of STEC/ETEC hybrids. Particularly, STEC/ETEC strains isolated from livestock feces and animal source foods mostly exhibited close relatedness with ETEC strains. These findings allow further exploration of the pathogenicity and virulence of STEC/ETEC hybrid strains and may serve as a data source for future comparative studies in evolutionary biology.

The effect of cancer on traditional, complementary and alternative medicine utilization in Korea: a fixed effect analysis using Korea Health Panel data.

BACKGROUND: Cancer-related incidence and mortality rates are rapidly increasing worldwide. However, no studies have examined the effect of cancer as a single factor on the use of traditional, complementary, and alternative medicine (T&CAM). We aimed to determine the effect of cancer occurrence on T&CAM utilization using Korea Health Panel (KHP) data. METHODS: We analyzed longitudinal data (49,380 observations) derived from 12,975 Korean adult participants with complete KHP data from 2011 to 2014 and 2016, and divided them into two groups based on cancer diagnosis. A panel multinomial logit model was used to assess whether the participants used T&CAM or conventional medicine or both in outpatient settings. Additionally, a negative binomial regression model was used to examine the effect of cancer on the number of outpatient visits for T&CAM. RESULTS: In total, 25.54% of the study participants in the cancer group used T&CAM, which was higher than that in the non-cancer group (18.37%, p < 0.0001). A panel multinomial logistic regression analysis using KHP data showed that cancer occurrence was significantly more likely to be associated with 'Using both Korean medicine and conventional medicine' (Coef. = 0.80, p = 0.017) and 'Not using Korean medicine but using conventional medicine' (Coef. = 0.85, p = 0.008) than 'Not using Korean medicine and conventional medicine.' A panel negative binomial regression showed a significant effect of cancer on increasing the number of T&CAM outpatient visits (Coef. = 0.11, p = 0.040). CONCLUSIONS: Our findings showed that cancer occurrence within an individual led to the simultaneous use of conventional medicine and T&CAM. In addition, the occurrence of cancer significantly increased the number of T&CAM outpatient visits among participants already using T&CAM. It was also found that T&CAM has been utilized more often by the most vulnerable people, such as medical beneficiaries and those with a low level of education.

Anticancer Activity of Bee Venom Components against Breast Cancer.

While the survival rate has increased due to treatments for breast cancer, the quality of life has decreased because of the side effects of chemotherapy. Various toxins are being developed as alternative breast cancer treatments, and bee venom is drawing attention as one of them. We analyzed the effect of bee venom and its components on breast cancer cells and reviewed the mechanism underlying the anticancer effects of bee venom. Data up to March 2022 were searched from PubMed, EMBASE, OASIS, KISS, and Science Direct online databases, and studies that met the inclusion criteria were reviewed. Among 612 studies, 11 were selected for this research. Diverse drugs were administered, including crude bee venom, melittin, phospholipase A2, and their complexes. All drugs reduced the number of breast cancer cells in proportion to the dose and time. The mechanisms of anticancer effects included cytotoxicity, apoptosis, cell targeting, gene expression regulation, and cell lysis. Summarily, bee venom and its components exert anticancer effects on human breast cancer cells. Depending on the mechanisms of anticancer effects, side effects are expected to be reduced by using various vehicles. Bee venom and its components have the potential to prevent and treat breast cancer in the future.

Traditional Korean Medicine Usage and Perception: a comparative study between the general population and the disabilities.

Objectives: This study is a comparative analysis of the satisfaction and recognition characteristics for traditional Korean medicine (TKM) in people with disabilities and the general population of Korea. Methods: Here, 5,000 subjects were categorized into two groups based on a disability rating using the data from the 2017 National Survey for the Usage of Korean Medicine. The relationships among the sociodemographic characteristics, TKM usage status, recognition of TKM usage, and recognition of the effectiveness of the TKM treatment were analyzed based on the disease. The response reliability was verified using the chi-square test analysis method. Results: Disabilities corresponded with low rates of high school or higher education (44%, 83.5%) and no jobs (56.9%, 33.5%), mostly the status of the low-income class with a monthly household income of < 1,500 USD (50.9%, 10.5%), poor health conditions (55.2%, 9.8%), high chronic disease prevalence rate (69.0%, 19.9%), high medical care rate (11.2%, 0.5%), and low commercial health insurance subscription rate (44%, 74.2%). Furthermore, people with disabilities visited TKM institutions more often (88.8%, 74.1%) with a high frequency TKM usage rate of ≥ 1-2 times a month (26.2%, 15.3%). They also reported that the cost of using the TKM was very high (14.7%, 8.8%) and that primarily the application of insurance benefits should be improved (52.6%, 47.5%). The treatment effectiveness for diseases was high for musculoskeletal disorders for both people with disabilities and the general population. Conclusion: Preferential application of insurance benefits for musculoskeletal diseases must be extended to the TKM treatment as well, as people with disabilities have a high recognition for these conditions with TKM. It is difficult to perform randomized controlled trials on people with disability. Therefore, large-scale observational and cohort studies should be conducted. We hope this study will help establish a suitable TKM policy for people with disabilities.

Monitoring of Heavy Metals and Pesticide Residues of Herbal Decoctions in Traditional Korean Medicine Clinics in Korea.

In this study, we investigated whether the levels of heavy metal and pesticide residues in herbal decoctions in Korea in 2019 were within normal limits. In total, 30 decoctions composed of multi-ingredient traditional herbs were sampled from traditional Korean medicine (TKM) clinics, TKM hospitals, and external herbal dispensaries in 2019. The decoctions were analyzed for heavy metal content such as lead, arsenic, and cadmium using inductively coupled plasma optical emission spectrometry. For mercury, an automatic mercury analyzer based on the gold amalgamation process was used. For pesticide residues, gas chromatography with electron capture detection and gas chromatography with mass selective detection were used for the analyses. Based on the testing, heavy metals were identified in most of the decoctions (Cd: 0.000-0.003 ppm, Pb: 0.003-0.023 ppm, As: 0.000-0.016 ppm, Hg: 0.000-0.002 ppm). Pesticide residues (e.g., total DDT, total BHC, aldrin, endrin, dieldrin) were not detected at all. All of these were no more than the limit values in preceding studies. Therefore, this study confirms that the contents of heavy metals and pesticides in herbal decoctions are within safe levels based on a previous study and provides evidence for establishing safety management standards for herbal decoctions in Korea.

Herbal Decoctions for the Levels of Sulfur Dioxide, Benzopyrene, and Mycotoxin from Traditional Korean Medicine Clinics: A Preliminary Study.

In this study, we investigated whether the levels of sulfur dioxide (SO2), benzopyrene, and mycotoxins in herbal decoctions in Korea in 2019 were within normal limits. In total, 30 decoctions composed of multi-ingredient traditional herbs were sampled from traditional Korean medicine (TKM) clinics, TKM hospitals, and external herbal dispensaries in 2019. The decoctions were analyzed for SO2, benzopyrene, and mycotoxins using 10 samples. SO2 and benzopyrene were not detected in any of the herbal decoctions. With regard to mycotoxins, aflatoxin B1 was not detected, but B2 was detected in 7 cases (0.00~0.04 ppb), G1 in 13 cases (0.03~0.29 ppb), and G2 in 9 cases (0.02~0.93 ppb). None of these values exceeded the restrictions in prior studies. Thus, we confirm that the amounts of SO2, benzopyrene, and mycotoxins in herbal decoctions are at safe levels and provides the basis of establishing safety management criteria for herbal decoctions.

Association between Sleep Duration and Symptoms of Depression Aged between 18 and 49: The Korea National Health and Nutrition Examination Survey (KNHANES â ¦) from 2016 to 2018.

This study aimed to determine the association between symptoms of depression and sleep duration in a representative sample of the Korean population. Using national cross-sectional data from the seventh Korea National Health and Nutrition Examination Surveys (KNHANES-VII), 5461 adults aged 18−49 years were analyzed using logistic regression models. The proportions of participants with total daily sleep durations (24 h) of <6 h, 6−8 h, and ≥9 h were 26.2%, 60.6%, and 13.3%, respectively. The proportions of individuals with symptoms of depression in the <6 h, 6−8 h, and ≥9 h sleep duration groups were 37.4%, 46.3%, and 16.3%, respectively. The odds ratios (ORs) were significantly higher in the <6 h and ≥9 h sleep groups than in the 6−8 h sleep group. There was a significant association between short (<6 h/day) and long (≥9 h/day) sleep duration and symptoms of depression among the general Korean population. In particular, our findings suggest that short sleep (<6 h/day) is more associated with symptoms of depression than long sleep (≥9 h/day).

Clinical Studies of Bee Venom Acupuncture for Lower Back Pain in the Korean Literature.

This study aimed to identify all of the characteristics of bee venom acupuncture (BVA) for the treatment of lower back pain (LBP) that are described in the Korean literature, and to provide English-speaking researchers with bibliometrics. Six Korean electronic databases and sixteen Korean journals on BVA treatment for back pain were searched up to February 2022. This report included and analyzed 64 clinical studies on BVA interventions for back pain and 1297 patients with LBP. The most common disease in patients with back pain was lumbar herniated intervertebral discs (HIVD) of the lumbar spine (L-spine). All studies used bee venom (BV) diluted with distilled water. The concentration of BVA for HIVD of L-spine patients with LBP ranged from 0.01 to 5.0 mg/mL; the dosage per treatment was 0.02-2.0 mL, and for a total session was 0.3-40.0 mL. The most used outcome measure was the visual analogue scale for back pain (n = 45, 70.3%), and most of the papers reported that each outcome measure had a positive effect. Korean clinical studies were typically omitted from the review research, resulting in potential language bias. This study provides clinical cases in Korea for future development and standardization of BVA treatment for back pain.

A Study on the Development of a Model for Providing Traditional Korean Medicine and Welfare Services for Community Care.

Objectives: This study aims to develop a community care model in traditional Korean medicine (TKM) by developing a community care participation model for the health of the elderly and deriving tasks to implement it. Methods: This study implemented a group interview with experts. A fact-finding survey was conducted targeting 16 local governments that are implementing a leading project to identify the status of TKM service provision and welfare service linkage in all regions. An expert group interview (FGI) targeted public and private sector experts for each job role, the former represented by those in charge of the central government's health care policy and administrative delivery system, and the latter by professors majoring in social welfare, professors majoring in health, and local TKM societies. After forming the expert groups, three expert group interviews were conducted. Results: Through collective interviews with experts, a model for providing TKM and welfare services in community integrated care was derived by dividing it into local and central government levels. The strategies and tasks for promoting TKM-oriented health welfare services were derived from 3 strategies, 8 tasks, and 20 detailed tasks. Conclusion: The core direction of the TKM health care model is the region-centered provision of TKM and welfare services. To this end, policy support for the use and linkage of health care service resources is required at the central government level, and linkage and provision of health welfare services centered on TKM are necessary through linkage and convergence between service subjects and between government health care projects.

Utilization of Traditional Korean Medicine Services by the Older Population: A Cross-Sectional Study.

Korean healthcare service is divided into conventional medicine and traditional Korean medicine (TKM). This cross-sectional study compared the older population (65 years and older) with two groups of the general population (19-50 years and 51-64 years) to understand the current patterns in the use of TKM services by the older population. Using data from the 2017 National Survey of TKM Usage, we analyzed the main purpose and diseases or symptoms for TKM use, the reason for choosing TKM over other types of medicine, and the treatments provided. Both age groups sought TKM services to "[treat] a disease". The top five diseases and symptoms in the older adult (65 and older) group were musculoskeletal and are as follows: arthritis and joint diseases (37.8%, n = 166), disc-related diseases (25.5%, n = 112), back pain (8.4%, n = 37), frozen shoulder and shoulder pain (7.7%, n = 34), and sprain (5.9%, n = 26). The most frequently used treatments for these diseases were acupuncture, moxibustion, cupping, and physiotherapy. The present study suggests that older adults primarily used TKM clinics for the treatment of musculoskeletal diseases. Further studies are necessary to assess the clinical effectiveness of conventional medicine versus TKM versus a combination of both in treating musculoskeletal disorders.
