Cognitive Behavioral Therapy for Migraine Headache: A Systematic Review and Meta-Analysis.

Background and Objectives: Migraine headaches are chronic neurological diseases that reduce the quality of life by causing severe headaches and autonomic nervous system dysfunction, such as facial flushing, nasal stuffiness, and sweating. Their major treatment methods include medication and cognitive behavioral therapy (CBT). CBT has been used for pain treatment and various psychogenic neurological diseases by reducing pain, disability, and emotional disorders caused by symptoms of mental illness and improving the understanding of mental health. This study aimed to evaluate the effectiveness and safety of CBT in treating migraines. Materials and Methods: Seven electronic databases were searched from the date of inception to December 2020. Randomized controlled studies (RCTs) using CBT as an intervention for migraine were included. The primary outcome of this study was to determine the frequency of migraines and the intensity of migraines on Visual Analog Scale (VAS), the frequency of drug use, Migraine Disability Assessment (MIDAS), and Headache Impact Test (HIT-6) index. The two authors independently conducted the data extraction and quality assessment of the included RCTs, and conducted meta-analysis with RevMan V.5.4. Results: Among the 373 studies, 11 RCTs were included in this systematic review. Seven out of the 11 RCTs were conducted in the USA, and four were conducted in the UK, Germany, Iran, and Italy, respectively. Headache frequency and MIDAS scores were statistically significant reduced. In the subgroup analysis, headache strength was significantly reduced. Two of the included studies reported adverse effects, including worsening of migraine intensity and frequency, respiratory symptoms, and vivid memory of a traumatic event. Conclusions: CBT for migraine effectively reduced headache frequency and MIDAS score in meta-analysis and headache intensity subgroup analysis, with few adverse events. Additional RCTs with CBT for migraine headaches are needed for a more accurate analysis.

The association between cold hypersensitivity in the hands and feet and chronic disease: results of a multicentre study.

BACKGROUND: Cold hypersensitivity in the hands and feet (CHHF) is a common symptom in Korea and patients with CHHF complain of coldness in the hands and feet in an environment that is not considered cold by unaffected people. In traditional East Asian medicine, CHHF is believed to be accompanied by various diseases and symptoms, and is considered a symptom that needs active treatment. CHHF is used for pattern identification in the cold pattern, yang deficiency, and constitution. This study aimed to examine the differences in frequencies of chronic diseases with respect to the presence of CHHF. METHODS: Disease history, CHHF, body measurements, and blood test survey data from 6149 patients collected by 25 medical institutes in Korea were obtained from the Korean Medicine Data Center. The participants were divided into CHHF (n = 1909) and non-CHHF groups (n = 3017) according to the CHHF survey. The differences in frequencies of 18 diseases were analysed using chi-square tests, and the odds ratios (ORs) for each disease according to CHHF status were examined via logistic regression with adjustment for age, sex, and body mass index (BMI). RESULTS: Based on chi-square test results, the CHHF group showed a higher frequency of the following diseases: anaemia, hypotension, chronic gastritis, reflux oesophagitis, chronic rhinitis, dysmenorrhoea, and gastroduodenal ulcer. Diseases found in lower frequencies were as follows: hypertension, diabetes mellitus, impaired fasting glucose, dyslipidaemia, stroke, fatty liver, and angina pectoris. In addition, from the logistic regression with adjustment for age, sex, and BMI, the CHHF group showed a lower OR in diabetes mellitus and dyslipidaemia than the non-CHHF group, but a higher OR in degenerative arthritis, chronic gastritis, gastroduodenal ulcer, reflux oesophagitis, and chronic rhinitis. CONCLUSIONS: This study showed that CHHF is associated with chronic disease. Further large-scale prospective studies are needed to validate these associations.

An assessment of the use of complementary and alternative medicine by Korean people using an adapted version of the standardized international questionnaire (I-CAM-QK): a cross-sectional study of an internet survey.

BACKGROUND: In Korea, there are two types of medical doctors: one practises conventional medicine (hereafter called a physician), and the other practises traditional medicine (hereafter called a Korean medical doctor). This study aimed to compare the provision of complementary and alternative medicine (CAM) by these providers to CAM use per self-judgement in Korea. METHODS: We analysed 1668 Korean people via an internet survey with the Korean adopted version of the I-CAM-Q, namely, the International Questionnaire to measure use of CAM, to understand whether respondents used CAM based either on a prescription or advice from a physician or a Korean medical doctor or on self-judgement. RESULTS: In the previous 12 months, the proportions of respondents who were treated by a physician, who were treated by a Korean medical doctor and who were not treated by anyone were 67.9, 20.7 and 14.2%, respectively. Among the respondents who received CAM based on a prescription or advice from a physician, traditional Korean medicine practices and dietary supplements were commonly used; only a small percentage used other CAM therapies. Respondents who received CAM based on a prescription or advice from a Korean medical doctor showed similar results. Acupuncture and moxibustion, traditional Korean medicines (decoction), or cupping were more commonly used. Korean traditional medicines as over-the-counter (OTC) drugs were more commonly used by respondents who received CAM therapy based on a prescription or advice from a physician than by those who received CAM therapy based on a prescription or advice from a Korean medical doctor. A total of 74% of the responders used any CAM by self-judgement in the previous 12 months. CONCLUSIONS: For the use of CAM in Korea, in addition to the Korean traditional medical care provided by Korean medical doctors, general physicians advised people regarding Korean traditional medical care and dietary supplements.

Comparative effects of artemisia vulgaris and charcoal moxa stimulating Zhongwan (CV 12) on body temperature in healthy participants: a cross-over single-blind randomized study.

OBJECTIVE: To evaluate the efficacy, safety, satisfaction, discomfort and patient preference of moxa cones of artemisia vulgaris and charcoal moxa. METHODS: This comparative study of moxibustion treatment with Artemisia vulgaris and charcoal moxa cone stimulating Zhongwan (CV 12) is a cross-over single-blinded, randomized clinical trial. A total of 40 healthy subjects (24 males and 16 females) participated in this study. Two subjects dropped out of the trial. Thirty-eight subjects were treated with Artemisia vulgaris and charcoal moxa cones for 30 min in a cross-over design. After treatment, the patients underwent a 30 minute waiting period, and then the temperatures at Tanzhong (CV 17), Zhongwan (CV 12) and Guanyuan (CV 4) were measured using digital infrared thermal imaging. RESULTS: After the use of Artemisia vulgaris moxa, the patients' body temperatures were slightly lowered at Tanzhong (CV 17), Zhongwan (CV 12) and Guanyuan (CV 4), but the changes were not statistically significant. After the use of charcoal moxa, the patients' body temperatures were somewhat increased at Zhongwan (CV 12) and Guanyuan (CV 4), but the changes were not statistically significant. After Artemisia vulgaris moxa use, the body temperature difference between Zhongwan (CV 12) and Guanyuan (CV 4) was significantly increased. After charcoal moxa use, the body temperature difference between Tanzhong (CV 17) and Zhongwan (CV 12) was significantly decreased in males and in the whole group. This change was caused by the difference in the moxibustion type and by gender differences. CONCLUSION: This pilot study found that moxibustion did not raise the body temperature, but temperature differences between acupoints were affected. Further large-scale randomized controlled trials are needed for the effect of moxibustion on body temperature.

KM110329 in adult patients with atopic dermatitis: a randomised, double-blind, placebo-controlled, multicentre trial--study protocol.

BACKGROUND: Atopic dermatitis is a chronic inflammatory skin disease with a high prevalence rate and a large socioeconomic cost. There are many treatments for atopic dermatitis, such as antihistamine, tacrolimus and corticosteroids. However, due to concern about the adverse effects, many patients seek alternative treatments. In this context, natural products are gaining interest. KM110329 is a functional food consisting of four herbs that are beneficial to skin health. The purpose of this study is to assess the efficacy and safety of KM110329 for atopic dermatitis. METHODS/DESIGN: This study is a randomised, double-blind, placebo-controlled and multicentre trial of KM110329. For this study, we will recruit 66 atopic dermatitis patients of both sexes, with ages ranging from 18 to 65, from three university hospitals. The participants will receive either KM110329 or a placebo twice a day for 8 weeks. The primary end point will be a change in the scoring atopic dermatitis (SCORAD) index. The secondary end points will include changes to the dermatology life quality index (DLQI) and transepidermal water loss (TEWL), among others. The outcomes will be measured at every visit. The study will be continued for 8 weeks and will include five visits with each subject (at screening and at 0, 1, 4 and 8 weeks). DISCUSSION: This trial will provide research methodologies for evaluate clinical efficacy and safety of KM110329 in adult patients with atopic dermatitis. In addition, we will evaluate the changes in the general skin health status and quality of life. TRIAL REGISTRATIONS: ClinicalTrials.gov NCT01692093.

Differential Association of Uncoupling Protein 2 Polymorphisms with Pattern Identification among Korean Stroke Patients: A Diagnostic System in Traditional Korean Medicine.

Uncoupling protein 2 (UCP2), a mitochondrial protein present in many organs and cell types, is known to dissipate the proton gradient formed by the electron transport chain. Its function is correlated with predictive parameters, such as obesity, diabetes, and metabolic syndromes. We analyzed the distribution of UCP2 polymorphisms in stroke patients diagnosed with one of the following four stroke subtypes based on the TKM standard pattern identification (PI): Qi-deficiency (QD), Dampness and Phlegm (D&P), Yin-deficiency (YD), and Fire and Heat (F&D). We studied a total of 1,786 stroke patients (397/QD, 645/D&P, 223/YD, and 522/F&D, 586/normal). Genotyping for the G-1957A, G-866A and A55V UCP2 polymorphisms was performed using the TaqMan. G-866A and A55V were significantly associated with the D&P and H&F subtypes. The frequency of subjects with the A allele of G-866A was significantly lower than the frequency of subjects with the GG type. The A55V polymorphism was also shown similar effect with G-866A in the dominant model. In contrast, no SNPs were shown to be associated with the QD or YD subtypes in this study. These results showed that the G-866A and A55V UCP2 polymorphisms may be genetic factors for specific PI types among Korean stroke patients.

Metabolomic analysis of Gyejibongnyeong-Hwan for shoulder pain: A randomized, wait-list controlled pilot trial.

BACKGROUND: In Korea, Gyejibongnyeong-Hwan (GBH), a herbal decoction used to treat blood stasis (BS), is widely used to treat shoulder pain in clinics. Nevertheless, the therapeutic mechanism of GBH in alleviating shoulder pain has not yet been elucidated. PURPOSE: In this study, we applied mass spectrometry-based metabolomics to explore the therapeutic mechanism of GBH in BS-induced shoulder pain. STUDY DESIGN: We conducted a two-center, randomized, wait-list controlled pilot trial to explore the therapeutic effect of GBH on shoulder discomfort related to BS. METHODS: A total of 40 participants with shoulder pain were randomly assigned to either the immediate treatment (GBH-Treat; n = 20) or waiting treatment (Wait-List; n = 20) group. A non-targeted metabolomics approach was then applied to investigate the therapeutic mechanism of GBH. RESULTS: After 8 weeks of treatment, the visual analog scale (VAS) scores for shoulder pain decreased significantly in the GBH-Treat and Wait-List groups compared with baseline VAS scores (p = 0.004 and p = 0.013, respectively). However, the VAS and BS scores were significantly more reduced in the GBH-Treat group than in the Wait-List group. The plasma metabolic pattern between GBH-Treat and Wait-List groups also differed significantly, which was shown by the score plot of a partial least-squared-discriminant analysis (R2 = 0.806 and Q2 = 0.229, p = 0.016). Arginine, bilirubin, carnitine, glutamine, maltol, mystic acid, N,N dimethylarginine, trimethylamine N-oxide, valine, kynurenine, and linoleic acid significantly contributed to the different metabolic patterns between the GBH-Treat and Wait-List groups (all p < 0.05). Pathway analysis revealed that these metabolites were involved in arginine biosynthesis and tryptophan metabolism, which are related to pain generation and transmission. We also confirmed that the ratio of kynurenine to tryptophan, one of the indicators for chronic pain and neuro-inflammation, was significantly lower in the GBH-Treat group than in the Wait-List group (p = 0.02). CONCLUSION: These results demonstrated that GBH may be a potential treatment option for shoulder pain, and it acts by regulating metabolic patterns. In particular, our study provides evidence for the use of GBH treatment for patients with should pain caused by BS, and we believe that our findings can provide evidence for precision medicine based on traditional Chinese medicine (TCM) or traditional Korean medicine (TKM). We also verified that metabolomics studies provide comprehensive understanding of herbal decoctions in TCM or TKM.

Effect of herbal medicine (Jodeungsan) on migraine: A double-blind randomized clinical trial.

Background: Migraine is a relatively common disease that has a significant effect on the daily activities of affected individuals. The purpose of this study was to explore the effects of herbal medicine (Jodeungsan, JDS) on migraine. Methods: Sixty-four patients with migraine were recruited and randomized to either the JDS or placebo group at a 1:1 ratio. The subjects received JDS or placebo daily for four weeks. The primary outcome was a change in the number of headache attack days (HADs), and the secondary outcome measures were the headache impact test (HIT), migraine-specific quality of life (MSQoL), the deficiency and excess pattern identification questionnaire (DEPIQ), the cold and heat pattern identification questionnaire (CHPIQ), and the blood stasis pattern questionnaire (BSPQ). Results: In all, 61 of the 64 patients took the investigational drugs for four weeks. The number of HADs did not significantly differ between the JDS and placebo groups at the end of the study. However, the HIT and MSQoL results showed significant improvement over the baseline in both groups. Conclusion: JDS did not have a significant effect on chronic migraine. Larger studies are needed to confirm this result. Trial registration: Clinical Research Information Service (https://cris.nih.go.kr/): KCT0003121.

Utilization of Complementary and Alternative Medicine among Korean Elite Athletes: Current Status and Future Implications.

The objective of the study was to explore the status of usage of complementary and alternative medicine (CAM) among Korean elite athletes. A survey was emailed to all Korean national sports federations recognized by the International Olympic Committee and the Olympic Council of Asia. A total of 705 Korean elite athletes participated in this study. The athletes had to be any of the following to participate in this survey: elite intercollegiate athletes, professional athletes, and national team athletes. 83.3% of the participants stated that they have previously experienced Korean medicine (KM). Compared to the general population in Korea, athletes had more experience (general population = 73.8%). The participants without experience mentioned that they either did not need any KM treatments (39.8%) or lacked information (39.8%) regarding KM treatments. The primary reason for the utilization of KM was the effectiveness of treatments. Therefore, 70.8% of the participants have mentioned recommending KM to others. Generally, athletes are worrisome that the consumption of herbal medicine may not be doping-free; however, it is vital to note that 62% of the participants expressed that prescribed herbal medicine is safe. Overall, this research demonstrates a high prevalence of KM usage by intercollegiate, professional, and national team athletes in Korea. Hence, this study's results may serve as the foundation in future research directions for promoting KM among Korean elite athletes.

Early antiallergic inflammatory effects of Rhus verniciflua Stokes on human mast cells.

Rhus verniciflua Stokes (RVS) is a traditional medicine used in Korea, Japan and China to treat various diseases including catharsis, diaphoretic gastritis and stomach cancer. However, the effects of RVS on allergic inflammatory diseases are unknown to date. This study showed the antiallergic inflammatory effects of RVS on human mast cells (HMC-1) which were stimulated by phorbol myristate acetate (PMA) and calcium ionophore A23187. RVS inhibited the expressions of TNF-alpha, IL-6 and IL-8 that were stimulated by treatment with both PMA and A23187. Among the mitogen-activated protein kinases (MAPKs), extracts of RVS suppressed the phosphorylation of ERK and p38, whereas RVS increased the phosphorylation of JNK in HMC-1. Consistent with the regulation of MAPKs, it was found that RVS inhibited the nuclear translocation of nuclear factor (NF)-kappaB via inhibition of the phosphorylation of IkappaB-alpha, which are important processes in controlling inflammatory responses. Taken together, these results suggest that RVS modulates the expressions of signal molecules related to allergic inflammatory responses mainly through the ERK signaling pathway, suggesting that RVS could be used as a treatment for mast cell-derived allergic inflammatory diseases.

Efficacy and safety of Onkyeong-tang in treating cold hypersensitivity in the feet of Korean women: protocol for a double-blind, randomized, placebo-controlled, parallel-group, multicenter clinical study.

BACKGROUND: Cold hypersensitivity in the hands and feet (CHHF) commonly affects Asian women, especially Korean women, and it negatively impacts the quality of life of the affected individuals. One commonly used herbal prescription for treating CHHF is Onkyeong-tang (OKT). Although OKT is widely used clinically in treating CHHF, no randomized clinical trial has been performed to evaluate the efficacy and safety of OKT in the treatment of cold hypersensitivity in the feet (CHF). This clinical trial aims to provide objective evidence for the basis of using OKT in the treatment of CHF in Korean women. METHODS: This trial will be a double-blind, randomized, placebo-controlled, parallel-group, multicenter pilot study. A total of 112 participants will be randomly divided into an OKT treatment group or a placebo group with a 1:1 ratio via a web-based randomization system. The OKT and placebo groups will receive prescribed medications orally three times per day (3 g each time) before or between meals for 8 weeks. The primary outcome studied will be the changes in Visual Analog Scale (VAS) scores of CHF from baseline. Secondary outcomes studied will be the VAS score changes of cold hypersensitivity in the hands, changes in the skin temperature of the hands and feet, total scores of the Korean version of the World Health Organization Quality of Life Scale-abbreviated version, and the results of the cold stress test. DISCUSSION: This trial will be the first clinical trial to assess the efficacy and safety of OKT in the treatment of CHF. We anticipate that the findings of the study will provide evidence for the basis of using OKT in treating CHF symptoms and generate basic data for designing a further large-scale randomized clinical trial.

Effectiveness of Gyejibongnyeong-Hwan for shoulder pain: study protocol for a randomised, wait-list controlled pilot trial.

BACKGROUND: Shoulder pain is an uncomfortable feeling in the muscle around the shoulder. The cause of myalgia is the accumulation of lactic acid in muscles and impaired blood circulation, which is called blood stasis in traditional East Asian medicine. This study aimed to explore the therapeutic effect of Gyejibongnyeong-Hwan (GBH) for shoulder discomfort related to blood stasis before and after treatment. METHODS/DESIGN: This study will be a double-centre, randomised, wait-list controlled pilot trial. Participants with shoulder pain and with a visual analogue scale score of 4 or higher out of 10, blood stasis score of 9 or higher, and triglyceride level of ≥150 mg/dl or total cholesterol level of ≥200 mg/dl will be recruited from two university hospitals. A total of 40 participants will be assigned to the immediate and waiting treatment groups. The immediate treatment group will receive GBH for 8 weeks on enrolment while the waiting treatment group will receive GBH for 8-16 weeks after 8 weeks of controlled waiting. The primary outcome is shoulder pain, and the secondary outcomes are the blood stasis score, blood pressure, ankle-brachial pressure index, brachial-ankle pulse wave velocity, body mass index, waist circumference, indexes of oximetry, and levels of blood lipid, blood sugar, resistin, C-reactive protein, serum amyloid P, and D-dimer. DISCUSSION: The results of this pilot trial will be the bases for a full-scale clinical trial of GBH. TRIAL REGISTRATION: Clinical Research Information Service, KCT0003837.

Herbal prescription for managing menopausal disorders: A practice survey in Korean medicine doctors.

BACKGROUND: The aim of this study was to investigate the clinical practice of Korean medicine doctors (KMDs) for managing menopausal disorders. METHODS: We conducted a web-based questionnaire for KMDs to respond to recommendations across the three main KM domains: major symptoms of menopausal disorders, herbal prescriptions, and pattern identification. RESULTS: We received responses from 227 doctors who have treated menopausal disorders. The major pattern identifications recommended by the doctors for the pre-, peri-, and postmenopausal phases, respectively, were depression of liver energy (59.5%), kidney yin deficiency (49.8%), and kidney yin deficiency (50.7%). The most frequent herbal remedies prescribed for the pre-, peri-, and postmenopausal phases were Jiawei shaoyao-san (58.1%), Jiawei shaoyao-san (48.5%), and Jiawei guipi-decoction (37.9%), respectively. CONCLUSION: The results of our clinical practice survey provide information on KMDs' clinical experiences of using herbal medicines and their use of pattern identification to manage menopausal disorders.

Efficacy and safety of ucha-shinki-hwan on korean patients with cold hypersensitivity in the hands and feet: Study protocol clinical trial (SPIRIT Compliant).

BACKGROUND: Cold hypersensitivity in the hands and feet (CHHF) is a common complaint in Asian female population especially in Korea. Due to the symptoms of CHHF the quality of individual's daily life can be degraded. Ucha-Shinki-Hwan (UCHA) is widely used in the treatment of various diseases including CHHF by harmonizing Yin and Yang, and improving the vitality of whole body. However, the efficacy of UCHA as a treatment option of CHHF has not been assessed in trials. Thus, we aimed to investigate the efficacy and safety of UCHA in Korean women with CHHF through this trial. METHODS: This study will be an exploratory, randomized, double-blind, placebo-controlled, parallel-group, multicenter trial. Korean women aged 19 to 59 years who complaint with CHHF will be enrolled from 5 university affiliated Korean medicine hospitals. A total of 164 subjects will be randomly assigned to a treatment group (UCHA) or a placebo group at a 1:1 ratio. The subjects will receive 2.5 g of either UCHA or placebo three times a day for 8 weeks. The primary outcome will be evaluated with the visual analog scale score of CHHF. The secondary outcome measures will be changes in skin temperature in extremities as measured by using a thermometer and the Korean version of the World Health Organization Quality of Life Scale Abbreviated Version. DISCUSSION: This study will be the first trial to explore the efficacy and safety of UCHA for CHHF patient. This will provide meaningful clinical information on herbal medicine treatment of CHHF and a clinical evidence for planning a full randomized clinical trial. DISCLOSURES AND ACKNOWLEDGMENTS: The authors report no competing interests. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov, ID: NCT03790033. Registered on (31 December 2018) PROTOCOL VERSION:: The final approved version of the trial protocol is V1.3. (25 January 2019).

Sophora flavescens Aiton inhibits the production of pro-inflammatory cytokines through inhibition of the NF kappaB/IkappaB signal pathway in human mast cell line (HMC-1).

The dried roots of Sophora flavescens Aiton (SFA) has been used in traditional medicine for treatment of inflammation, gastrointestinal hemorrhage, diarrhea, and asthma. In the present study, we investigated the effect of SFA on the inflammatory allergic reaction using human mast cell-1 (HMC-1). SFA (200mg/kg) inhibited the mast cell-mediated passive cutaneous anaphylaxis reaction in vivo and the release of histamine from rat peritoneal mast cells by compound 48/80. In addition, the expression levels of phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187-stimulated TNF-alpha, IL-6, and IL-8 were also decreased by SFA treatment. In molecular mechanism level, this study showed that SFA inhibited the nuclear translocation of nuclear factor (NF) kappaB through inhibition of the phosphorylation and degradation of IkappaB-alpha, which is an inhibitor of NF kappaB. Moreover, SFA suppressed PMA plus A23187-induced phosphorylation of the mitogen-activated protein kinase p38 and c-jun N-terminal kinase. The inhibited induction of NF kappaB promoter by SFA was determined using luciferase activity. These results suggest that SFA could be used as a treatment for mast cell-derived allergic inflammatory diseases.

Selective cytotoxic effects on human cancer cell lines of phenolic-rich ethyl-acetate fraction from Rhus verniciflua Stokes.

Rhus verniciflua Stokes (RVS) is a plant with a long history of medicinal use in Eastern Asia. RVS has been widely used to treat gastritis, stomach cancer and atherosclerosis. The cytotoxic effects of different solvent fractions from an RVS ethanol extract were measured in 11 human cancer cell lines. The study showed that the ethyl-acetate (EtOAC) fraction was the most cytotoxic. This fraction contains a number of phenolic compounds, and this phenolic-rich EtOAC fraction was particularly effective against gastric and breast cancer cells. A purified phenolic-rich EtOAC fraction (PPEF) had a stronger apoptotic effect on these cells. Liquid chromatography-mass spectrometry (LC-MS) analysis showed that the PPEF contained gallic acid, protocatechuic acid, fisetin, sulfuretin, butein and 8 unknown compounds. There were only small amounts of flavonoids: fisetin, sulfuretin and butein. The results showed that PPEF induces apoptosis only in gastric and breast cancer cell lines, but not in lung, colon or liver cancer cell lines. Therefore, PPEF may have a significant potential as an organ-specific anti-cancer agent.

The Relationship between Cold Hypersensitivity in the Hands and Feet and Health-Related Quality of Life in Koreans: A Nationwide Population Survey.

AIM: We investigated the distribution of cold hypersensitivity in the hands and feet (CHHF) and examined the association between CHHF and health-related quality of life (HRQOL) among Koreans. METHODS: Stratified multistage sampling was used for random selection of 2,201 adults. HRQOL was assessed using the Short-Form 12-Item Health Survey (SF-12). Cold hypersensitivity was measured using a new self-report questionnaire to score the extent of cold sensation in their hands, feet, and abdomen using a 7-point scale. The correlation between CHHF and HRQOL was analysed using multiple regression analysis. RESULTS: Cold hypersensitivity was present in the hands of 21.6%, the feet of 23.0%, and the abdomen in 22.5% of participants. Cold hypersensitivity in the hands and feet was observed in 17.9%, at least one body part (hands, feet, or abdomen) in 34.2%, and all three body regions in 12.3% of participants. The prevalence of cold hypersensitivity was significantly higher among women than among men, irrespective of the involved body part. Cold hypersensitivity scores in the hands and feet correlated negatively with body mass index, but not with age. The physical component summary (PCS) and mental component summary (MCS) of the SF-12 were both significantly lower in women with than in those without CHHF. Among men, only the PCS was significantly lower in the CHHF group. Multiple regression analysis, adjusted for sociodemographic variables, age, sex, and body mass index (BMI), confirmed that CHHF had negative effects on PCS and MCS. CONCLUSIONS: CHHF is more common in women and in individuals with a lower BMI. CHHF has an independent negative effect on HRQOL.

Perceptions of using herbal medicines for managing menopausal symptoms: a web-based survey of Korean medicine doctors.

BACKGROUND: Most women experiencing menopause have sought out traditional treatment options to relieve their symptoms. The aim of this study, which used a web-based survey, was to investigate perceptions of Korean medicine doctors (KMDs) on managing menopausal symptoms with herbal medicines. METHODS: We developed and then sent a questionnaire via email to a total 497 KMDs in obstetrics and gynecology affiliated with the Society of Korean Medicine. The questionnaire consisted of three categories and a total of 26 items focusing on major menopausal symptoms, prescriptions, pattern identification, and background characteristics. RESULTS: Out of the 497 KMDs, we received responses from 48 doctors, a response rate of 9.7%. The most common symptoms of menopausal disorder perceived by responded KMDs were hot flashes (22.9%), sleep disorders (18.2%), systemic fatigue (12.5%), and sweating (12.0%). The herbal medicines reported to be the most effective when treating patients with menopausal disorders were Jiawei shaoyao-san (12.5%), Jiawei guipi-decoction (11.8%). The responding KMDs recommended one to two months of treatment for female menopausal disorder, using two to three doses of herbal medicine per day in combination with traditional Korean medicine (KM) therapies such as acupuncture, moxibustion, cupping, and pharmacopuncture. CONCLUSION: The results of this survey may provide information about doctor's perceptions on using herbal medicines to manage patient's menopausal symptoms. Future studies should be done with a larger sample size to overcome the limitation of this study and to examine how KM is used for treating menopausal symptoms in clinical practice.

Korean medicines for poor ovarian reserve in infertility: A protocol for a multicenter observational study.

INTRODUCTION: Many infertile patients have used Korean medicines (KMs) as a primary or adjuvant therapeutic method to improve in vitro fertilization success rates. The aim of this multicenter observational study is to investigate the effects of KMs on poor ovarian reserve (POR) in infertile patients. METHODS AND ANALYSIS: We will perform a prospective multicenter observational study. This study will recruit 50 women between 25 and 44 years of age with infertility caused by POR from among patients who visit the KM clinic. All participants will visit the KM clinic on the 2nd or 3rd day of menstruation to receive the KMs. KM treatment will be delivered for 3 menstrual cycles (3 months) and will include herbal decoction, acupuncture, or moxibustion on demand. Every participant will be assessed based on KM clinical symptoms, a quality of life questionnaire, and ovarian reserve test results. ETHICS AND DISSEMINATION: The study was approved by Institutional Review Board of Semyung University (SMU-IM-190501). The results will be published in a peer-reviewed journal and will be disseminated electronically and in print. TRIAL REGISTRATION NUMBER: Clinical Research Information Service: KCT0004209.
