The purpose of this study was to analyze the Korean medicine treatment methods for Postherpetic Neuralgia (PHN) in Korea. There were 5 online databases searched (OASIS, NDSL, RISS, KISS and KMBASE) for studies which were related to PHN. A total of 12 studies were selected. Various treatments such as acupuncture, herbal medicine, and moxibustion were reported treatments for PHN, some of which included Western medicine and Korean medicine treatment. Korean herbal medicine was the most frequently used treatment method, followed by manual acupuncture. Sipjeondaebotanggami was the most frequently used prescription. Poria Sclerotium was the most frequently used principal herb, followed by Angelicae Gigantis Radix, Zingiberis Rhizoma, and Ginseng Radix. GB44, LI4, LR3 were the common acupoints used for the treatment of PHN. CV12 was the most frequently used moxibustion point, and gabapentin was the most frequently used concomitant Western drug. Additional research on Korean medicine treatment of PHN is expected in the future.

This study was to assess the alteration of circulating complement factor Ba (CFBa) within 11 to 17 weeks of gestation and its association with subsequent gestational diabetes mellitus (GDM) and its delivery outcome.Biochemical parameters and blood samples were collected from 399 pregnant women within 11 to 17 weeks of gestation. At 24 to 28 weeks of gestation, all participants underwent 75-g oral glucose tolerance test and were assigned to GDM group (Two groups of 74 well-matched patients who maintained balance in terms of baseline characteristics. The levels of CFBa in pregnant women who later developed GDM were significantly higher than those in healthy pregnant women [0.4(0.1-0.8)High level of the CFBa within 11 to 17 weeks of gestation increases the risk of subsequent GDM, and maybe a biomarker for predicting GDM.

Reduced heart rate variability (HRV) in response to stress is a biomarker of emotion dysregulation (ED) and is related to posttraumatic stress disorder (PTSD), yet less is known about its role with dissociation in trauma-exposed adults. The goals of the current study were to examine unique patterns of associations between ED, dissociation, and PTSD with HRV at 15, 30, and 45 minutes (T1, T2, T3) following an acute psychosocial stressor task in a sample of 49 trauma-exposed, urban-dwelling Black women. Associations with baseline psychophysiology measures were also examined. ED and dissociation were assessed using self-report; PTSD was determined using a semi-structured interview. Heart rate (HR) and HRV, indexed with low frequency/high frequency (LF/HF) ratio and respiratory sinus arrhythmia (RSA), were measured with electrocardiogram recordings. ED and dissociation were positively correlated with LF/HF ratio at T3 (p

Objectives: This study is designed to statistically analyze data of outpatients visiting for recent 3 years. The purpose is to identify tendencies of patients who visit the hospitals before and after COVID-19. Methods: This study retrospectively analyzed the medical records of 452,487 patients who visited to the Daejeon·Cheonan·Cheongju Korean Medicine Hospital of Daejeon University from January 1, 2018 to August 31, 2020. The data is classified according to year, month, gender, age, and visit type. The statistical analysis was performed using IBM SPSS 25.0. Results: The total number of patients decreased in 2020 compared to before 2020, and the number of patients in each hospital also decreased from the previous year. According to the year of each hospital, the difference by year was not statistically significant at Daejeon Hospital, but Cheonan and Cheongju Hospital showed statistical difference. The change in monthly according to the year by hospital has continued to decrease from January to March in 2020, unlike the previous year, which recovered from a decline in March. In the analysis of patients by age, there was no statistically significant difference in the number of patients in the above 60s according to the year, while those under 60s have a tendency to significantly decrease.. Conclusion: We expect that the results of this study will be used as reference materials in analyzing effects of COVID-19 at health care utilization.

Background: The purpose of this study was to statistically analyze the treatment effect and patient satisfaction of traditional Korean medicine, including acupotomy treatment of cervical herniated intervertebral disc. Methods: This was a retrospective study of 22 patients who received traditional Korean medicine including acupotomy treatment amongst all patients diagnosed with cervical herniated intervertebral discs at the Korean Medicine hospital in Daejeon, Korean, from January 01, 2020 to April 30, 2021. The clinical data from patient medical records were statistically analyzed. Results: The Numeric Rating Scale, the European Quality of Life 5 Dimensions, and the European Quality of Life Visual Analogue Scale questionnaire scores were each compared before and after traditional Korean medicine treatment, including acupotomy, showed significantly improved scores after treatment (p < 0.001). Out of a total of 22 patients, 11 rated the treatment “very satisfactory” (50%), 5 “satisfactory” (22.7%), 5 “indifferent” (22.7%), 1 “unsatisfactory” (4.5%), and 0 “very unsatisfactory” (0%). Of the total 22 patients, 17 patients (77.3%) were willing to have further treatment, and 5 patients (22.7%) were not willing. Conclusion: Traditional Korean medicine treatment including acupotomy was an effective treatment for cervical herniated intervertebral discs. To determine the effect of an individual application (e.g., acupotomy) of traditional Korean medicine treatment for cervical herniated intervertebral disc, a prospective, controlled study is needed.

BackgroundComplement factor H (CFH) has been found to be associated with insulin resistance. This study assessed the correlation between CFH and other clinical parameters, and determined whether CFH played a role in gestational diabetes mellitus (GDM) and adverse pregnancy outcomes.MethodsA total of 397 pregnant women were included for analysis in this nested case-control study. Clinical parameters and serum were collected within the 11-17th gestational age at the first prenatal visit. At 24–28 weeks of gestation, a 75 g oral glucose tolerance test was performed and subjects were divided into a GDM (n = 80) and a non-GDM control group (n = 317). The delivery data were also followed. The serum CFH level was assayed by ELISA.ResultsCFH was higher in GDM than in non-GDM controls (280.02 [58.60] vs. 264.20 [68.77];P = 0.014). CFH level was moderately associated with pre-pregnancy body mass index (BMI), BMI and total triglycerides (TG), and slightly associated with gestational age, low density lipoprotein cholesterol (LDL-C), total cholesterol (TC) in GDM and non-GDM (allP P 10CFH levels (allP P P P < 0.05) in all pregnant women respectively. Following binary logistic regression, CFH was not independently associated with GDM and related pregnant outcomes.ConclusionsThe CFH in 11-17th weeks of gestation might be affected by many factors, including BMI, TG, gestational age, ALP, TB, age and UA. CFH was not an independent risk factor for GDM and avderse pregnancy outcomes.

A patient diagnosed with Guillain-Barre syndrome (GBS) suffering from numbness in the toes and fingers, paralysis in the face, and back pain received intravenous immunoglobulin on December 28, 2019. Without an improvement in symptoms the patient was admitted to a Korean medicine hospital on January 1, 2020 to receive combined Korean medicine treatment including herbal medicine (Sipjeondaebo-tanggami and Hyangbujasunkipalmul-tang), acupuncture treatment, moxibustion, cupping treatment, and physical therapy. Treatment was administered over 51 days, of which 17 days were during hospitalization. Paralysis of facial muscle, and numbness in fingers and toes were evaluated using the Yanagihara score and numeric rating scale (NRS) score, respectively. Facial paralysis improved (21 to 40 based on Yanagihara score) and paresthesia of the hands and feet disappeared (NRS score 6-7 to NRS score 0). There were no side effects or sequela. This study suggested combined Korean medicine treatment may be effective for the treatment of GBS.

Background The Global Health Security (GHS) Index has been developed to measure a country’s capacity to cope with a public health emergency; however, evidence for whether it corresponds to the response to a global pandemic is lacking. This study performed a multidimensional association analysis to explore the correlation between the GHS Index and COVID-19-associated morbidity, mortality, and disease increase rate (DIR) in 178 countries (regions). Methods The GHS Index and COVID-19 pandemic data – including total cases per million (TCPM), total deaths per million (TDPM), and daily growth rate – were extracted from online databases. The Spearman correlation coefficient was applied to describe the strength of the association between the GHS Index, sociological characteristics, and the epidemic situation of COVID-19. DIRs were compared, and the impact of the GHS Index on the DIR by the time of “lockdown” was visualized. Results The overall GHS Index was positively correlated with TCPM and TDPM, with coefficients of 0.34 and 0.41, respectively. Countries categorized into different GHS Indextiers had different DIRs before implementing lockdown measures. However, no significant difference was observed between countries in the middle and upper tiers after implementing lockdown measures. The correlation between GHS Index and DIR was positive five days before lockdown measures were taken, but it became negative 13 days later. Conclusions The GHS Index has limited value in assessing a country's capacity to respond to a global pandemic. Nevertheless, it has potential value in determining the country’s ability to cope with a local epidemic situation.

Background: This study was designed to statistically analyze the year, gender, age, insurance type, and condition/disease of patients who were admitted to the Department of Acupuncture and Moxibustion Medicine at DaeJeon Korean Medicine Hospital over a 5-year period (2015-2020).Methods: Patients who visited the Department of Acupuncture and Moxibustion Medicine at DaeJeon Korean Medicine Hospital were classified according to year, gender, age, insurance type, and condition/disease. The statistical analysis was performed using IBM SPSS 23.0.Results: There is an increasing number of patients attending the Department of Acupuncture and Moxibustion Medicine year-on-year over the 5-year period, with a higher frequency of females than males each year. The largest age groups represented in these patients were those aged in their 50s, followed by those aged in their 40s, and 60s. Furthermore, the number of patients using health insurance was greater than those using automobile insurance each year. Of the 5,061 patients, the most common group was the patients (n = 991) who reported sprain and strain of cervical spine, followed by lumbar spine, lumbar herniation of the intervertebral disc, and facial paralysis.Conclusion: The number of patients seeking traditional Korean medicine treatment continues to increase, particularly in the 40s to 60s age group, with a larger proportion using health insurance and sprain or strain of the cervical spine. The results of this study may be used as a local (Daejeon) reference to develop Korean medicine policies, such as setting up medical benefits for patients using Korean medicine hospitals.

Wolf's isotopic response refers to the occurrence of a novel skin disease at the site of a preceding treated or untreated skin disease. Although the most common preceding skin disease was found to be herpes zoster (HZ), HZ-related dermatological phenomena are not well known in the literature. We report a case of HZ granulomatous dermatitis in a 77-year-old female with a previous history of hypertension, diabetes mellitus, chronic kidney disease, and HZ. She presented with a 3-month history of a pruritic skin lesion on her right thigh. The location of the lesion was consistent with a previous HZ site. Histopathological examination revealed lympho- histiocytic infiltration in the superficial dermis, forming a granulomatous structure. Based on clinical and histopathological findings, we made a diagnosis of granulomatous dermatitis at a previous HZ site. We assumed that the lesion arose from an isotopic response of Wolf. The patient was treated with topical steroids for 3 months and showed clearance of the lesion and symptom. We suggest that treatment should be based on the individual disease, which in our case was topical steroid.

The passage of US immigrant-related policies at the federal, state, and local level is on the rise. These policies may affect child health through several mechanisms. We performed a systematic review of English-language, peer-reviewed, quantitative studies examining US immigrant-related policies and the mental and physical health of youth in immigrant families. We searched PubMed and five social science databases for studies published between 1986 and 2019. Two independent reviewers screened the studies and appraised study quality. Of the final 17 studies, ten studies examined birth outcomes and seven studies examined other outcomes in childhood and adolescence (e.g., self-rated health). Generally, exclusionary policies were associated with worse health outcomes and inclusive policies were associated with better health outcomes. Several studies did not observe an association, but only one study found an association of the opposite direction. In that study, similar trends in different policy environments and across foreign-born and US-born women suggest alternative causes for the observed association. Overall, we find that exclusionary policies are, at best, neutral, but likely harmful towards child wellbeing, while inclusive policies can be beneficial.

Background Accurately predicting the risk level for a lymph node metastasis is critical in the treatment of non-small cell lung cancer (NSCLC). This study aimed to construct a novel nomogram to identify patients with a risk of lymph node metastasis in T1-2 NSCLC based on positron emission tomography/computed tomography (PET/CT) and clinical characteristics. Methods From January 2011 to November 2017, the records of 318 consecutive patients who had undergone PET/CT examination within 30 days before surgical resection for clinical T1-2 NSCLC were retrospectively reviewed. A nomogram to predict the risk of lymph node metastasis was constructed. The model was confirmed using bootstrap resampling, and an independent validation cohort contained 156 patients from June 2017 to February 2020 at another institution. Results Six factors [age, tumor location, histology, the lymph node maximum standardized uptake value (SUVmax), the tumor SUVmax and the carcinoembryonic antigen (CEA) value] were identified and entered into the nomogram. The nomogram developed based on the analysis showed robust discrimination, with an area under the receiver operating characteristic curve of 0.858 in the primary cohort and 0.749 in the validation cohort. The calibration curve for the probability of lymph node metastasis showed excellent concordance between the predicted and actual results. Decision curve analysis suggested that the nomogram was clinically useful. Conclusions We set up and validated a novel and effective nomogram that can predict the risk of lymph node metastasis for individual patients with T1-2 NSCLC. This model may help clinicians to make treatment recommendations for individuals.

In the present study, we analysed the effects of SNP rs174547 (T/C) in the fatty acid desaturase 1 (FADS1) gene on long-chain PUFA levels. Four databases were searched to retrieve related literature with keywords such as fatty acid (FA), SNP,FADS1and rs174547. A meta-analysis of the data was performed using Stata12.0 software, including summary statistics, test for heterogeneity, evaluation of publication bias, subgroup analysis and sensitivity analysis. The associations between rs174547 inFADS1and seven types of FA, and Δ-5 (D5D) and Δ-6 fatty acid desaturase (D6D) activity were assessed based on the pooled results from eleven papers. A total of 3713 individuals (1529 TT and 2184 TC + CC) were included. The results demonstrated that minor C allele carriers of rs174547 had higher linoleic acid (LA;P α-linolenic acid (P = 0·020) levels, lower γ-linolenic acid (GLA;P = 0·001) and arachidonic acid (P = 0·024) levels, and lower D5D (P = 0·005) and D6D (P = 0·004) activities than the TT genotype group. Stratification analysis showed that minor C allele carriers of rs174547 had higher LA and lower GLA levels and lower D6D activities in plasma (LA,P P P P P = 0·001; D6D activity,P = 0·001) than the TT genotype group. In conclusion, minor C allele carriers of the SNP rs174547 were associated with decreased activity of D5D and D6D.

Background: This study aims to statistically analyze and compare the curative effect and satisfaction level between typical traditional Korean medicine treatment and nonsurgical spinal decompression treatment.Methods: Of the patients who were diagnosed with the cervical or lumbar herniated intervertebral disc at the Department of Acupuncture and Moxibustion Medicine at the Daejeon Korean Medicine Hospital from April 14th to August 25th, 2019, this study retrospectively analyzed the medical records of 31 patients who underwent nonsurgical spinal decompression treatment and traditional Korean medicine (assigned to Group A) and another 31 patients who received typical traditional Korean medicine alone (assigned to Group B). The clinical data were analyzed using IBM SPSS Version 23.0.Results: No statistically significant differences appeared in terms of sociodemographic, condition, and therapeutic characteristics, except whether the patient received Western medicine treatment, before or after a treatment with traditional Korean medicine. Group A exhibited higher variations in numeric rating scale, EuroQol- 5 dimension and EuroQol visual analogue scale scores compared to Group B as determined by independent sample t test and analysis of covariance. In addition, the satisfaction score of Group A was higher than that of Group B The result of cross analysis revealed that desire for continued treatment in Group A was higher than that of Group B.Conclusion: This retrospective observational study showed that the patients with nonsurgical spinal decompression treatment reported a greater reduction in pain, improved quality of life and satisfaction than patients receiving typical traditional Korean medicine.

This case report describes a 60-year-old female patient diagnosed with intercostal neuropathy and vertebral compression fractures which occurred following an electric shock injury. The patient received acupuncture, pharmacopuncture, and herbal medicine administration between February 10th, 2020 and April 25th, 2020. The pain level in the thoracic and left intercostal areas was assessed using the Numerical Rating Scale. The Self-report of the Leeds Assessment of Neuropathic Symptoms and Signs Pain Scale were used to diagnose neuropathic pain. The Neuropathic-Pain -Scale was used to evaluate the degree of neuropathic symptoms. The Oswestry Disability Index and the European Quality of Life-5 Dimensions were used to assess quality of life scales and functional disorder. Following combined Korean medicine treatment, the patient exhibited reduced levels of pain and significant improvement in functional disorder symptoms and quality of life.

Background and Objectives Surgery for bilateral chronic otitis media (COM) is usually performed sequentially, not simultaneously. The main reason is to prevent iatrogenic bilateral conductive hearing loss during recovery period. However, with asymmetric hearing loss, the difference in patient inconvenience between sequential and simultaneous surgery may be the same. This study evaluates the efficacy of simultaneous COM surgery in patients with asymmetric hearing.Subjects Materials and Method From 2012 to 2018, 9 patients underwent simultaneous bilateral COM surgery. The period of patients’ hospital stay, the success rate of tympanoplasty, tolerability for operation, and hearing thresholds were analyzed statistically.Results For the 8 same-day surgery patients, the mean hospital period was 4.4±0.7 days, which was much shorter than that of sequential surgery (8 days). Tympanoplasty was successful in all patients without complications. In the better side, the preoperative/postoperative mean air conduction thresholds (AC) were 62.97±12.89 dB/47.81±19.07 dB (p=0.017), the bone conduction thresholds (BC) were 46.72±10.31 dB/37.66±16.99 dB (p=0.161) and the air-bone gaps (ABG) were 16.25±8.81 dB/10.16±7.78 dB (p=0.176). In the worse side, the preoperative/ postoperative mean AC were 86.56±18.22 dB/72.18±29.43 dB (p=0.035), BC were 53.28± 11.10 dB/48.13±18.41 dB (p=0.173), and ABG were 33.28±11.22 dB/24.06±14.80 dB (p=0.500). In both ear, the postoperative AC and BC were better than or equivocal to those of the preoperative value, and the result was similar with each of the unilateral ear audiological results.Conclusion Despite the fact that there is no complete consensus to date, simultaneous bilateral COM surgery can be an option when patients have asymmetric hearing loss. Simultaneous bilateral COM surgery could save time, cost, and lead to similar results with sequential surgery, so it could be a considerable surgical option for patients with bilateral COM.

Objectives. To investigate the neurocognition of aged patients with chronic tinnitus and reveal the possible association between tinnitus severity and cognitive function, with attention to mild cognitive impairment (MCI).Methods. Fifty-eight elderly patients (≥65 years old) with chronic tinnitus (≥6 months) were prospectively enrolled in this study. All patients assessed the neurocognitive batteries including the Korean version of the patient health questionnaire-9 (K-PHQ-9), the Lawton instrumental activities of daily living scale (K-IADL), and the Montreal cognitive assessment (MoCA-K). After initial evaluation to exclude moderate or severe cognitive impairment by a psychiatrist, the patients were classified into two groups: MCI and non-MCI, according to the MoCA-K scores (cutoff value, 22/23). All patients underwent audiological examinations including psychoacoustic tests of tinnitus.Results. Of 58 patients, 10 (17.2%) met the MCI criteria. The tinnitus handicap inventory (THI) score in the MCI group was significantly higher than that in the non-MCI group. Based on multivariate regression analysis, a significant association between tinnitus severity and MoCA-K score was also detected. Specifically, bothersome tinnitus (THI score ≥30) was closely linked to the presence of MCI. Meanwhile, the impact of MCI on both K-PHQ-9 and K-IADL scores was not evident in patients with chronic tinnitus.Conclusion. Tinnitus severity appears to be a potential independent determinant for predicting the MCI, suggesting the underlying mechanism between chronic tinnitus and cognitive deficit. Given that MCI highly links to dementia, the evaluation of cognitive functions in aged patients with chronic tinnitus need to be considered at the initial assessment of tinnitus.

This study aimed to investigate the utility of facial nerve ultrasonography in the functional and structural assessment of early-stage Bell's palsy and the prognostic value of facial nerve ultrasonography in Bell's palsy.Prospective longitudinal study.Single center, a university-affiliated neurology clinic.Patients with unilateral Bell's palsy who had visited our clinic within 3 days of symptom onset were enrolled in this study. Demographic information and House-Brackmann grade were collected. Electrophysiologic studies and facial nerve ultrasonography were then performed. The facial nerves on each side were scanned longitudinally with a 5- to 12-MHz probe. The diameter of the facial nerves with and without the sheath was measured at the proximal and distal portions. Follow-up examinations, including House-Brackmann grade analysis, electrophysiologic studies, and facial nerve ultrasonography, were performed after 2 months.Fifty-four patients with unilateral Bell's palsy were enrolled, and 22 underwent the follow-up examinations. The diameters of the facial nerves were larger on the affected side than on the unaffected side at the proximal and distal portions (Ultrasonography could be a useful tool for evaluating the facial nerve in Bell's palsy. Nevertheless, further studies are needed to demonstrate its prognostic value.

The major pathologies of Alzheimer's disease (AD) are amyloid plaques and hyperphosphorylated tau. The deposition of amyloid plaques leads to synaptic dysfunction, neuronal cell death, and cognitive impairment. Among the neurotransmitters, glutamate is the most abundant in the mammalian brain and plays an important role in synaptic plasticity. With respect to synaptic transmission, metabotropic glutamate receptor 5 (mGluR5) is highly affected by amyloid pathology. However, the neuropathologic changes in the protein expression of mGluR5 in AD remain unclear. Therefore, to elucidate the alteration in mGluR5 expression with the progression of AD, we performed serial behavioral tests, longitudinal imaging studies, and histopathological immunoassay for both 5xFAD (n = 14) mice and age-matched wild-type mice (n = 14). The 5xFAD mice started showing severe hyperactivity and memory impairment from 7 months of age. In addition, mGluR5 positron emission tomography revealed that while the binding values in the wild-type mice were similar over time, those in 5xFAD mice fluctuated from 5 months of age. Furthermore, the 5xFAD mice presented a 35% decrease in the binding values of their cortical and subcortical areas at 9 months of age compared with those at 3 months of age. Magnetic resonance spectroscopy and histopathological studies showed similar changes. In conclusion, mGluR5 availability changes with age, and mGluR5 positron emission tomography could successfully detect this synaptic change in the 5xFAD mice.

BackgroundAccumulating literature has shown the predictive values of inflammation and nutrition-based biomarkers in the prognosis of oesophageal cancer but with inconsistent findings.MethodWe performed a meta-analysis to systematically evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), C reactive protein-to-albumin ratio (CAR), systemic inflammation index (SII), prognostic nutritional index (PNI), Glasgow Prognostic Score (GPS) and modified Glasgow Prognostic Score (mGPS) in oesophageal cancer. The outcome indicators include the overall survival (OS), disease-free survival (DFS) and cancer-specific survival (CSS). We applied pooled HR, sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and area under the curve together with 95% CI to estimate the predictive accuracy.ResultsA total of 72 studies, including 22 260 patients, were included in the meta-analysis. Elevated NLR, PLR CAR, SII, GPS, mGPS and decreased LMR and PNI were associated with poor OS of oesophageal cancer. A high level of NLR, PLR and GPS was related to poor DFS. A high level of NLR and GPS was related to poor CSS. The summarised AUC of CAR (0.72, 95% CI: 0.68 to 0.75) and mGPS (0.75, 95% CI: 0.71 to 0.78) surpassed any other indicators.ConclusionsClinical indicators such as NLR, PLR, LMR, PNI, SII, CAR, GPS and mGPS have the moderate predictive ability in OS, DFS and CSS of oesophageal cancer. The pretreatment level of CAR and mGPS showed an outstanding prediction value in 5-year OS for oesophageal cancer.

Background Terminal ileal (TI) ulcers are occasionally detected in asymptomatic individuals and mostly resolve without any treatment. In patients with ulcerative colitis (UC), TI ulcers are infrequently observed without evidence of backwash ileitis. However, the clinical significance and natural course of the lesions are unclear. The aim of our study was to evaluate the frequency and clinical implications of TI ulcers in patients with UC. Methods We retrospectively reviewed 397 patients with UC via successful TI intubation during colonoscopy. We compared the clinical characteristics of patients manifesting TI ulcers with those who did not. The natural course of TI lesions was also investigated during the follow-up periods. Results Forty-one patients (10.3%) showed TI ulcers without evidence of inflammation in the right colon. The patients with and without TI ulcers were not different in terms of baseline characteristics, disease activity and extent at the time of the UC diagnosis, proximal extension, Mayo endoscopic score at the last endoscopic examination, medication history, UC-related hospitalization, and relapse during follow-up periods. Of the 30 patients who underwent follow-up colonoscopy in patients with TI ulcers, 23 (76.7%) showed resolution of TI ulcer. In addition, patients with remaining TI ulcers did not differ in disease activity and biopsy results compared with those with resolving TI ulcers. Conclusions Discrete TI ulcers are more common in patients with UC, compared with the healthy cohort. No significant clinical impact on disease extension and severity is found.

(1) Background: Nutrition is a key determinant of sarcopenia in later life. (2) Methods: A systematic review of prospective cohort studies examining association of diet quality with muscle mass (MM), muscle strength (MS) or physical performance (PP) among older adults was conducted. A total of 22,885 results were obtained from a literature search in MEDLINE via PubMed and EMBASE up to November 2020. Inclusion criteria included diet quality assessment via dietary indices or statistical approaches, a sample of adults aged 45 years and over at baseline in a longitudinal study design. (3) Results: Of the 22,885 cohort studies, 14 studies were eligible. Meaningful results were obtained for the Mediterranean diet and Nordic diet regarding the decrease of sarcopenia risk, however results from non-European countries were inconsistent. In addition, due to the insufficient number of studies on Japanese Food Guide Spinning Top (JFG-ST), dietary variety score (DVS), and dietary quality index-international (DQI-I), effectiveness was difficult to prove. Studies using factor analysis to examine dietary patterns suggested that the risk of sarcopenia is increased with a high in saturated fat diet such as westernized pattern etc. (4) Conclusion: In this systematic review it was found that various diet qualities are meaningful to a decreased risk of sarcopenia.

OBJECTIVES To investigate registered nurses' awareness and implementation of oral health care in patients who are hospitalized in general wards or intensive care units (ICUs) in South Korea. METHODS This research was performed as a descriptive survey of 149 nurses working in nine general hospitals with at least 100 beds in major Korean cities. RESULTS Approximately half (40.9%) of the survey respondents reported providing oral health care for hospitalized patients but that relevant protocols were not available at most hospitals or wards (89.5%). Nurses working in an ICU were significantly more likely to provide oral health care than those working in general wards (83.9% vs 15.1%; P

Background: The purpose of this study was to analyze the medical dispute cases in Acupuncture and Moxibustion treatment, and present the guidelines of treatment to prevent medical disputes. Methods: Korean Acupuncture and Moxibustion Medicine Society medical dispute cases from January 2013 to September 2018 were collected and analyzed.

This case report relates to a 40-year old male patient diagnosed with ankylosing spondylitis who was treated with acupotomy and traditional Korean medicine. He showed a significant improvement in joint range of motion (ROM) in cervical and lumbar vertebrae, and in pain and functional disorder symptoms. The patient received acupotomy, acupuncture, pharmacopuncture, herbal medicine and physical therapy (November 26, 2018 to December 17, 2018). Joint ROM for cervical and lumbar vertebrae was measured, and the pain level was assessed using a numerical rating scale. The functional disorder and quality of life scales were also assessed using the Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Disease Activity Index, Korean Health Assessment Questionnaire, and Modified Health Assessment Questionnaire. After applying acupotomy and traditional Korean medicine, the patient exhibited increased joint ROM and reduced pain, also in conjunction with improved responses in functional disorder and quality of life. ©2019 Korean Acupuncture & Moxibustion Medicine Society.

The aim of this study was to report on the resorption of herniated nucleus pulposus following acupotomy treatment. Two patients were treated with acupotomy which included integrative Korean Medicine treatment, for either cervical, or lumbar herniated nucleus pulposus. Magnetic Resonance Imaging was used to produce images before and after (several months) treatment. The Numerical Rating Scale scores and Range of Motion were used to assess the patients at admission and discharge. In both cases, substantial resorption of the respective herniated disc was observed in the magnetic resonance images, with a decrease in the Numerical Rating Scale score. Range of Motion improved in 1 case. This study shows that acupotomy treatment may be a clinically effective treatment for herniated nucleus pulposus resorption and pain relief.

Varicella zoster virus (VZV) can invade the brainstem or brain via the glossopharyngeal, vagus , or facial nerve, resulting in brainstem inflammation or encephalitis. We report the case of a 66-year-old male patient with a primary manifestation of medulla injury of the glossopharyngeal and vagus nerves, combined with a medulla lesion, who was misdiagnosed with lateral medullary syndrome. Facial nerve injury and earache subsequently occurred and human herpes virus 3 (VZV) was detected by second-generation sequencing of the cerebrospinal fluid. The final diagnosis was varicella zoster encephalitis, which improved after antiviral therapy.

OBJECTIVE To investigate the effects of cavitating lesions involving the internal auditory canal (IAC) in subjects with cochlear otosclerosis with regard to poststapedotomy hearing outcome. STUDY DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS A retrospective chart review of 134 subjects with otosclerosis treated from January 2011 to June 2017 at Seoul National University Bundang Hospital was conducted. Sixteen subjects (23 ears) with temporal bone computed tomography (TBCT)-confirmed cochlear otosclerosis who underwent stapedotomy were included in the study. MAIN OUTCOME MEASURES Pure tone audiometry (PTA) (i.e., air and bone conduction; AC and BC, respectively) thresholds and air-bone gap (ABG), measured at 6 months postoperatively were compared between cochlear otosclerosis with and without IAC involvement (IAC group and non-IAC group, respectively). RESULTS A total of 14 of 23 ears showed involvement of the IAC. There were no significant differences in age, side of otosclerosis, or preoperative hearing threshold between the two groups. The mean postoperative AC and BC thresholds and ABG of the IAC group were significantly poorer (45.7 dB, 33.8 dB, and 11.8 dB, respectively) than those of the nonIAC group (24.1 dB, 20.0 dB, and 4.1 dB, respectively). CONCLUSIONS Cochlear otosclerosis with cavitating lesions involving the IAC showed significantly poorer postoperative audiological outcomes than those without any cavitating lesion. Cavitation extending to the IAC may act as a third window providing a route for sound energy shunting, and thus precluding successful hearing outcome in some subjects with cavitating otosclerosis after stapedotomy.

This research aimed to evaluate the potential inhibitory effect of mineral-rich Jeju lava sea water (JLSW) on lipid accumulation. This study optimized the calcium (Ca): magnesium (Mg) ratio (5:1, 2.5:1, 1:1) of JLSW and evaluated the effect on lipid accumulation in 3T3-L1 cells using Oil Red O staining. JLSW with a high Ca:Mg ratio (5:1) suppressed lipid accumulation in 3T3-L1 adipocytes. Based on these in-vitro results, the effects of JLSW on lipid accumulation were investigated in C57BL/6 J mice fed high-fat diets for 14 weeks. Epididymal adipose tissue weight was significantly decreased in mice that received JLSW with a hardness of 800 or 100 mg/L compared to HFD. Adipocyte size was significantly reduced in mice treated with JLSW with a hardness of 20 mg/L in comparison with HFD. Thus, long-term intake of JLSW may be expected to have anti-obesity effects due to the reduction of lipid accumulation.

Background: Several studies have shown that the over activation of complement factor B(CFB) was related to obesity, insulin resistance(IR) and type 2 diabetes mellitus. This study was to assess whether circulating complement factor Ba (CFBa) within 11 to 17 weeks of gestation is associated with subsequent gestational diabetes mellitus (GDM) or not.Methods: Biochemical parameters and blood samples were collected from 399 pregnant women within 11 to 17 weeks of gestation. At 24 to 28 weeks of pregnancy, all participants underwent 75-g oral glucose tolerance test (fasting for more than 8 hours before blood sampling) and were assigned to GDM group(n=80) and normal control group(n=319). Perinatal data were collected after delivery. A propensity score-matched (PSM) analysis was performed to reduce the impact of confounding factors on glucose metabolism during pregnancy between the two groups.Results: Two groups of 74 well-matched patients who maintained balance in terms of baseline characteristics. The levels of CFBa in pregnant women who later developed GDM were significantly higher than those in healthy pregnant women [0.4(0.1-0.8) vs. 0.2(0.2-0.3), P=0.031]. Logistic regression results confirmed that the level of CFBa was an independent influencing factor for the occurrence of GDM (OR=1.52, 95% CI: 1.25-1.85, P=0.000). Further grouping according to the quartile of CFBa level, it was found that the incidence of GDM in category 3 was markedly higher than that in the first and the second categories. Conclusions: High level of the CFBa within 11 to 17 weeks of gestation increased the risk of subsequent GDM, and maybe a biomarker for predicting GDM.

Tuberculosis (TB) remains a global public health threat. Misdiagnosis and delayed therapy of sputum smear-negative TB can affect the treatment outcomes and promote pathogen transmission. The application of Xpert MTB/RIF assay in bronchoalveolar lavage fluid (BALF) has been recommended but needs clinical evidence. We carried out a prospective study in the Nanjing Public Health Medical Center from September 2018 to August 2019. Pulmonary tuberculosis (PTB) patients were enrolled in the study if they had negative results of sputum smear. We compared the performance of Xpert MTB/RIF assay in sputum and BALF using sputum culture as the reference. In addition to this, we applied parallel tests using sputum culture, sputum-based Xpert MTB/RIF assay and BALF-based Xpert MTB/RIF assay to jointly detect smear-negative PTB using clinical diagnosis as the reference. With mycobacterial culture as the reference standard, Xpert MTB/RIF of BALF showed a higher sensitivity (14/16, 87.5%), but a relatively lower specificity (57/92, 62.0%). Xpert MTB/RIF of sputum showed relatively lower sensitivity (6/10, 60.0%) and higher specificity (63/88, 71.6%). Compared with sputum culture, Xpert MTB /RIF assay reduced the median detection time of MTB from 30 to 0 days, which significantly shortened the diagnosis time of the smear-negative TB patients. Among the combined detections, the positive detection proportion was improved with significant differences comparing with sputum culture only, from 11.1% (10/90) to 46.7% (42/90) (P < 0.05). Our study showed Xpert MTB/RIF in BALF had a better performance in detecting MTB of smear-negative patients.

Importance Compared with older patients, young adults with a history of myocardial infarction (MI) tend to have a higher burden of psychosocial adversity. Exposure to early-life stressors may contribute to the risk of adverse outcomes in this patient population, potentially through inflammatory pathways. Objective To investigate the association of early-life trauma with adverse events and examine whether inflammation plays a role. Design, Setting, and Participants This cohort study included patients aged 18 to 60 years with a verified history of MI in the past 8 months from a university-affiliated hospital network. Baseline data were collected from June 2011 to March 2016, and follow-up data were obtained through July 2019. Analysis began September 2019. Exposures Early-life trauma was assessed using the Early Trauma Inventory–Self Report short form (ETI-SR-SF), both as a continuous and as a binary variable at the threshold of a score of 7 or higher. Inflammatory biomarkers, interleukin 6, and C-reactive protein were obtained at baseline. Main Outcomes and Measures A composite end point of recurrent MI, stroke, heart failure hospitalization, and cardiovascular death over a median 3-year follow-up. Results Of 300 patients, the mean (SD) age was 51 (7) years, 198 (66%) were African American, and 150 (50%) were women. Compared with participants with MI with an ETI-SR-SF score less than 7, those with a score of 7 or higher had higher levels of interleukin 6 and C-reactive protein at baseline. Compared with participants with an ETI-SR-SF score less than 7, those with a score of 7 or higher were at a greater risk for adverse outcomes, with a hazards ratio of 2.3 (95% CI, 1.3-3.9). Results remained consistent in multivariable analysis. Further adjustment for C-reactive protein rendered the results no longer statistically significant. Early-life trauma displayed a dose-dependent response when analyzed as a continuous variable and by quartiles. Conclusions and Relevance Early-life trauma is an independent risk factor for adverse outcomes in young and middle-aged individuals with a history of MI. Neurobiological mechanisms leading to lifetime activation of systemic inflammatory cascades may be implicated.

ObjectivesWith a marginally effective vaccine and no significant breakthroughs in new treatments, a sensitive and specific method to distinguish active tuberculosis from latent tuberculosis infection (LTBI) would allow for early diagnosis and limit the spread of the pathogen. The analysis of multiple cytokine profiles provides the possibility to differentiate the two diseases.DesignSystematic review and meta-analysis.Data sourcesPubMed, Cochrane Library, Clinical Key and EMBASE databases were searched on 31 December 2019.Eligibility criteriaWe included case–control studies, cohort studies and randomised controlled trials considering IFN-γ, TNF-α, IP-10, IL-2, IL-10, IL-12 and VEGF as biomarkers to distinguish active tuberculosis and LTBI.Data extraction and synthesisTwo students independently extracted data and assessed the risk of bias. Diagnostic OR, sensitivity, specificity, positive and negative likelihood ratios and area under the curve (AUC) together with 95% CI were used to estimate the diagnostic value.ResultsOf 1315 records identified, 14 studies were considered eligible. IL-2 had the highest sensitivity (0.84, 95% CI: 0.72 to 0.92), while VEGF had the highest specificity (0.87, 95% CI: 0.73 to 0.94). The highest AUC was observed for VEGF (0.85, 95% CI: 0.81 to 0.88), followed by IFN-γ (0.84, 95% CI: 0.80 to 0.87) and IL-2 (0.84, 95% CI: 0.81 to 0.87).ConclusionCytokines, such as IL-2, IFN-γ and VEGF, can be utilised as promising biomarkers to distinguish active tuberculosis from LTBI.PROSPERO registration numberCRD42020170725.

Supplemental Digital Content is available in the text, Background: Degenerative knee osteoarthritis (KOA) shows an increase in morbidity with improvement in the living conditions and extended lifespans. Treatment for degenerative KOA has been gaining attention since it significantly affects the life of the elderly population and is also associated with increased expenses for medical services and high socioeconomic costs. Treatments for degenerative KOA include nondrug therapy, drug therapy, and surgical treatment. For cases that show little response to conservative treatment but have not involved severe deformation of the knee, procedures such as arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation can be performed. However, effective treatment is required for patients experiencing sustained knee pain after surgery. Although studies confirming the therapeutic effects of acupuncture or thread-embedding acupuncture (TEA) treatment for degenerative KOA have been reported, clinical studies on a combination of TEA and electroacupuncture (EA) in patients complaining of knee pain after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation have not yet been reported. Therefore, this study aimed to evaluate the effectiveness and safety of this combination treatment in patients with persistent knee pain after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation. Methods/design: This study has been designed as a 2-group, parallel, single-center, randomized, controlled, assessor-blinded trial. Thirty-six patients with degenerative KOA who complained of pain even after arthroscopic surgery, autologous chondrocyte implantation, or autologous osteochondral transplantation will be randomized to either the (TEA + EA + Usual care) group or the (Usual care only) group in a 1:1 ratio. The patients in the (TEA + EA + Usual care) group will receive TEA treatment once a week for 4 weeks for a total of 4 sessions and EA twice a week for a total of 8 sessions while continuing usual care. The (Usual care only) group will only receive usual care for 4 weeks. To assess the efficacy of the TEA and EA combination treatment, the visual analogue scale, the Korean version of the Western Ontario and McMaster Universities Osteoarthritis Index, the EuroQol 5-Dimension 5-Level, and the doses of the rescue drug taken will be evaluated at baseline (1W) and weeks 2 (2W), 4 (4W), 6 (6W), and 8 (8W). The primary efficacy endpoint is the mean change in visual analogue scale at week 4 (4W) compared to baseline. Adverse events will be assessed at every visit. Discussion: This study will provide useful data for evaluating the clinical efficacy and safety of TEA and electroacupuncture combination treatment for improving pain and quality of life after surgery for degenerative KOA.

Alzheimer&rsquo, s disease (AD) is a progressive neurodegenerative disease. In this study, to investigate the effect of microglial elimination on AD progression, we administered PLX3397, a selective colony-stimulating factor 1 receptor inhibitor, to the mouse model of AD (5xFAD mice). Amyloid-beta (A&beta, ) deposition and amyloid precursor protein (APP), carboxyl-terminal fragment &beta, ionized calcium-binding adaptor molecule 1, synaptophysin, and postsynaptic density (PSD)-95 levels were evaluated in the cortex and hippocampus. In addition, the receptor density changes in dopamine D2 receptor (D2R) and metabotropic glutamate receptor 5 were evaluated using positron emission tomography (PET). D2R, tyrosine hydroxylase (TH), and dopamine transporter (DAT) levels were analyzed in the brains of Tg (5xFAD) mice using immunohistochemistry. PLX3397 administration significantly decreased A&beta, deposition following microglial depletion in the cortex and hippocampus of Tg mice. In the neuro-PET studies, the binding values for D2R in the Tg mice were lower than those in the wild type mice, however, after PLX3397 treatment, the binding dramatically increased. PLX3397 administration also reversed the changes in synaptophysin and PSD-95 expression in the brain. Furthermore, the D2R and TH expression in the brains of Tg mice was significantly lower than that in the wild type, however, after PLX3397 administration, the D2R and TH levels were significantly higher than those in untreated Tg mice. Thus, our findings show that administering PLX3397 to aged 5xFAD mice could prevent amyloid pathology, concomitant with the rescue of dopaminergic signaling, suggesting that targeting microglia may serve as a useful therapeutic option for neurodegenerative diseases, including AD.

Background While there have been disagreements concerning whether obesity and increase in body weight elevate the risk of dementia, variability in body weight has been recently recognized as a new biometric associated with a high risk for a number of diseases. This nationwide, population‐based cohort study examined the association between body weight variability and dementia. Methods A total of 2,812,245 adults (mean age, 51.7 years; standard deviation, 8.6) without a history of dementia who underwent at least three health examinations between 2005 and 2012 in a nationwide cohort were followed‐up until the date of dementia diagnosis (based on prescribed drugs and disease code) or until 2016 (median follow‐up duration, 5.38 years; interquartile range, 5.16–5.61). Cox regression models were used to evaluate the risk of Alzheimer's disease and vascular dementia according to body weight variability. Results The hazard ratios (95% confidence intervals) of the highest quartiles of variability were 1.42 (1.35–1.49) for Alzheimer's disease and 1.47 (1.32–1.63) for vascular dementia compared to the lowest quartile group as a reference. This association was consistent in various subgroup analyses and sensitivity analyses. Conclusions Body weight variability could predict Alzheimer's disease and vascular dementia, which may provide new insights into the prevention and management of dementia., Body weight variability could be a potential risk factor for Alzheimer's disease and vascular dementia, which may provide new insights for dementia prevention.

The study of cognitive impairment associated with hearing loss has recently garnered considerable interest. Epidemiological data have demonstrated that hearing loss is a risk factor for cognitive decline as a result of aging. However, no previous study has examined the effect of hearing loss in patients with cognitive problems such as Alzheimer’s disease. Therefore, we investigated the effect of conductive hearing loss in an Alzheimer’s mouse model. Positron emission tomography (PET) and magnetic resonance imaging (MRI) were used to evaluate changes in glucose metabolism and gray matter concentrations in the 5xFAD Alzheimer’s Disease (AD) transgenic mouse model with and without conductive hearing loss (HL). Conductive hearing loss was induced using chronic perforation of the tympanic membrane. Behavioral data from the Y-maze and passive avoidance tests revealed greater memory deficits in the AD with HL (AD-HL) group than in the AD group. Following induction of hearing loss, lower cerebral glucose metabolism in the frontal association cortex was observed in the AD-HL group than in the AD group. Although lower glucose metabolism in the hippocampus and cerebellum was found in the AD-HL group than in the AD group at 3 months, the gray matter concentrations in these regions were not significantly different between the groups. Furthermore, the gray matter concentrations in the simple lobule, cingulate/retrosplenial cortex, substantia nigra, retrosigmoid nucleus, medial geniculate nucleus, and anterior pretectal nucleus at 7 months were significantly lower in the AD-HL group than in the AD group. Taken together, these results indicate that even partial hearing loss can aggravate memory impairment in Alzheimer’s disease.

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder and the leading cause of dementia, but therapeutic treatment options are limited. Taurine has been reported to have neuroprotective properties against dementia, including AD. The present study aimed to investigate the treatment effect of taurine in AD mice by functional molecular imaging. To elucidate glutamate alterations by taurine, taurine was administered to 5xFAD transgenic mice from 2 months of age, known to apear amyloid deposition. Then, we performed glutamate positron emission tomography (PET) imaging studies for three groups (wild-type, AD, and taurine-treated AD, n = 5 in each group). As a result, brain uptake in the taurine-treated AD group was 31–40% higher than that in the AD group (cortex: 40%, p p p p > 0.05) and 3–14% lower than that in the WT group (cortex: 10%, p > 0.05; striatum: 15%, p > 0.05; hippocampus: 14%, p > 0.05; thalamus: 3%, p > 0.05). However, we did not observe differences in Aβ pathology between the taurine-treated AD and AD groups in immunohistochemistry experiments. Our results reveal that although taurine treatment did not completely recover the glutamate system, it significantly increased metabolic glutamate receptor type 5 brain uptake. Therefore, taurine has therapeutic potential against AD.

Purpose: To compare the effect of intervention providing home modifications and assistive devices based on MOHO theory with home exercise on people with disability in time use, competence and values of occupational performance and activity limitations.Methods: Participants were 20 people with disabilities due to deficits in central nervous system. Eleven people in the experimental group partook in environmental modifications and assistive device intervention and nine people in the control partook in home exercise programmes. A total of eight sessions were progressed, one pre-test, six sessions of interventions and one post-test. Occupational Questionnaire (OQ) was used to evaluate one's time use. Occupational Self Assessment (OSA) was used to test the competence and values of one's everyday occupational performance. Activity Limitations Measure (ACTIVLIM) was used to assess the activity limitation of one's functional ability. Wilcoxon signed rank test was used to analyse the comparison of the pre-post of time use, competence and values of occupational performance, and activity limitations. Mann-Whitney U was used to compare between both groups.Results: Among the four occupational areas of OQ, the participation time in ADL significantly increased and rest significantly decreased in the experimental group (p

Recent advances in molecular genetic testing (MGT) have improved identification of genetic aetiology of candidates for cochlear implantation (CI). However, whether genetic information increases CI outcome predictability in post-lingual deafness remains unclear. Therefore, we evaluated the outcomes of CI with respect to genetic aetiology and clinical predictors by comparing the data of study subjects; those with an identified genetic aetiology (GD group), and those without identifiable variants (GUD group). First, we identified the genetic aetiology in 21 of 40 subjects and also observed genetic etiologic heterogeneity. The GD group demonstrated significantly greater improvement in speech perception scores over a 1-year period than did the GUD group. Further, inverse correlation between deafness duration and the 1-year improvement in speech perception scores was tighter in the GD group than in the GUD group. The weak correlation between deafness duration and CI outcomes in the GUD group might suggest the pathophysiology underlying GUD already significantly involves the cortex, leading to lesser sensitivity to further cortex issues such as deafness duration. Under our MGT protocol, the correlation between deafness duration and CI outcomes were found to rely on the presence of identifiable genetic aetiology, strongly advocating early CI in individual with proven genetic aetiologies.
