Protective effect of regular physical activity against diabetes-related lower extremity amputation.

BACKGROUND: Foot ulcers are a major complication of diabetes mellitus that increase morbidity and mortality in patients with diabetes, affect their quality of life, and increase the overall social burden. A considerable number of patients with diabetic foot ulcers (DFUs) require amputations every year. METHODS: This nation population-based study included 1 923 483 patients with diabetes who underwent regular health screening through the National Health Insurance Service during January 2009 and December 2012. We investigated the association between changes in physical activity (PA) status and the incidence of lower extremity amputation (LEA). Based on changes in PA status, participants were categorized into four groups: "remained inactive," "remained active," "active-to-inactive," and "inactive-to-active." RESULTS: Regular PA is an independent factor associated with a decreased risk of LEA in patients with diabetes. During the follow-up period, 0.23% (n = 4454) of the patients underwent LEA. Compared with the "remained inactive" group, the "remained active" group were at the lowest risk of LEA (adjusted hazard ratio 0.5888; 95% confidence interval 0.524-0.66). A protective effect of regular PA against LEA was observed in the "remaining active" group. CONCLUSIONS: Our findings suggest a protective role of PA against LEA in individuals with diabetes. This highlights the importance of recommending appropriate levels of PA for patients with diabetes. The study also showed a dose-response relationship, indicating that engaging in vigorous-intensity PA was most beneficial, and higher amounts of PA may provide additional benefits.

The analgesic effect of acupuncture in neuropathic pain: regulatory mechanisms of DNA methylation in the brain.

Recent research has demonstrated that chronic pain, resulting from peripheral nerve injury, leads to various symptoms, including not only allodynia and hyperalgesia but also anxiety, depression, and cognitive impairment. These symptoms are believed to arise due to alterations in gene expression and neural function, mediated by epigenetic changes in chromatin structure. Emerging evidence suggests that acupuncture can modulate DNA methylation within the central nervous system, contributing to pain relief and the mitigation of comorbidities. Specifically, acupuncture has been shown to adjust the DNA methylation of genes related to mitochondrial dysfunction, oxidative phosphorylation, and inflammation pathways within cortical regions, such as the prefrontal cortex, anterior cingulate cortex, and primary somatosensory cortex. In addition, it influences the DNA methylation of genes associated with neurogenesis in hippocampal neurons. This evidence indicates that acupuncture, a treatment with fewer side effects compared with conventional medications, could offer an effective strategy for pain management.

Smart filtering facepiece respirator with self-adaptive fit and wireless humidity monitoring.

The widespread emergence of airborne diseases has transformed our lifestyle, and respirators have become an essential part of daily life. Nevertheless, finding respirators that fit well can be challenging due to the variety of human facial sizes and shapes, potentially compromising protection. In addition, the current respirators do not inform the user of the air quality in case of continuous long-term use. Here, we introduce a smart filtering facepiece respirator incorporating a humidity sensor and pressure sensory feedback for self-fit adjusting and maintaining an adequate fit. The humidity detection sensor uses laser-induced graphene, and the pressure sensor array based on the dielectric elastomeric sponge monitors the respirator contact on the user's face, providing real-time closed-loop feedback and the wearer's fitting status. Those membrane sensors show outstanding performance, such as a low humidity hysteresis of 0.131 % and a precise pressure detection limit of 0.23 ± 0.02 kPa. As a result of the self-fit adjusting mode, the overall fit factor is increased by 10 % on average compared to the commercial respirator. This significant improvement in fit factor, coupled with the innovative design, has the potential to develop next-generation facepiece respirators as essential personal protective equipment.

SPP1+ macrophages in HR+ breast cancer are associated with tumor-infiltrating lymphocytes.

Breast cancer categorized into hormone receptor-positive (HR+), HER2-positive (HER2+), and triple-negative (TNBC) subtypes, exhibits varied outcomes based on the number of tumor-infiltrating lymphocytes (TILs). To explore the divergent roles of TIL levels across different subtypes, we employed single-cell RNA sequencing on 31 patients with breast cancer. HR+ breast cancer with high TIL levels (TIL-high) revealed increased SPP1+ macrophages, increased SPP1 expression in other monocytes/macrophages (mono/macro) subgroups, and enriched pathways associated with extracellular matrix (ECM) remodeling in mono/macro. Moreover, cell-cell interaction analyses revealed enhanced SPP1, MIF, and FN1 signaling in the interaction between SPP1+ macrophages and T-cells in TIL-high HR+ breast cancer. Spatial transcriptomics data highlighted the close proximity of SPP1+ macrophages, CD8+ T-cells, and CD4+ T-cells in TIL-high HR+ breast cancer. Our findings unveil the novel influence of SPP1+ macrophages on T-cells in TIL-high HR+ breast cancer, potentially explaining the poor prognosis and offering insights for targeted interventions.

Integrative Korean medicine treatment for low back pain with radiculopathy caused by Bertolotti syndrome: A CARE-compliant article and retrospective review of medical records.

RATIONALE: Bertolotti syndrome (BS) is characterized by radiculopathy caused by structural anomalies. Despite the structural deformity, conservative treatment is predominantly recommended due to surgery-related complications. Because of the diagnosis complexity, the incidence and contributing factors of BS, remain controversial. We report the case of a patient with BS who was treated with integrative Korean medicine (IKM). Moreover, we evaluated the epidemiological characteristics of lumbosacral transitional vertebrae (LSTV) from medical records of patients diagnosed with LSTV at 4 different medical clinics of Korean medicine. PATIENT CONCERNS: A 33-year-old male patient with low back pain and severe radiculopathy was diagnosed with BS (Castellvi Type II) on magnetic resonance imaging at a local orthopedic clinic. Additionally, the medical records of patients with BS who had been treated with IKM in 4 different institutions of Korean medicine were analyzed, and the characteristics of patients suffering from BS were identified. DIAGNOSES, INTERVENTIONS, AND OUTCOMES: The patient underwent IKM treatment for 40 days as an inpatient. The patient's condition was assessed using the Euroqol 5-dimension index and Oswestry Disability Index, and symptom severity was measured using the Numeric Rating Scale. IKM was effective in improving pain and functional disability without causing any adverse effects. In a retrospective review of medical records, the study identified symptom trends reported by patients with LSTV. LESSONS: IKM demonstrates potential efficacy in BS management, with notable trends in LSTV-related symptomatology warranting further investigation.

Pharmacopuncture therapy for adhesive capsulitis: A pragmatic randomized controlled pilot study.

Background: Although several studies have reported the effectiveness of acupuncture treatment for adhesive capsulitis (AC), research on pharmacopuncture therapy for AC remains limited. We compared the effectiveness and safety of pharmacopuncture and physiotherapy for AC. Methods: This pragmatic, randomized, controlled, parallel-group pilot study enrolled patients with limitations of shoulder movement and a numeric rating scale (NRS) score for shoulder pain ≥5 randomized (1:1) to the pharmacopuncture therapy (PPT) and physiotherapy (PT) groups. Treatment sessions were administered twice weekly for 6 weeks, and the participants were followed up for 13 weeks after randomization. The primary outcome was the NRS score for shoulder pain, and the secondary outcomes were the visual analog scale (VAS), Shoulder Pain and Disability Index (SPADI), range of motion (ROM), patient global impression of change (PGIC), EuroQol 5-Dimension 5-Level (EQ-5D-5L), and Short Form 12 Health Survey (SF-12) scores. The intention-to-treat (ITT) analysis was set as the primary analysis. Results: Among 50 participants, for the primary endpoint (week 7) the PPT group showed a significantly superior improvement in NRS, VAS, SPADI, ROM for flexion, ROM for abduction, and EQ-5D-5L scores. The ROM for extension, ROM for adduction, physical component summary, and patient global impression of change were significantly better in the PPT than in the PT group, and these effects were sustained until week 13. Conclusion: In this pilot study, PPT showed better effects than PT, confirming the feasibility of a follow-up main study. Trial registration: Clinicaltrials.gov (NCT05292482) and cris.nih.go.kr (KCT0007198).

All-in-one wearable drug efficacy assessment systems for bulbar muscle function using amyotrophic lateral sclerosis animal models.

Preclinical studies are crucial for developing amyotrophic lateral sclerosis drugs. Current FDA-approved drugs have been created by monitoring limb muscle function and histological analysis of amyotrophic lateral sclerosis model animals. Drug candidates for this disease have yet to be tested for bulbar-onset type due to the limitations of traditional preclinical tools: excessive animal use and discrete detection of disease progress. Here, our study introduces an all-in-one, wireless, integrated wearable system for facilitating continuous drug efficacy assessment of dysphagia-related muscles in animals during natural eating behaviors. By incorporating a kirigami-based strain-isolation mechanism, this device mounted on the skin of animals mitigates electromyography signal contamination caused by unpredictable animal movements. Our findings indicate this system, measuring the progression of motor neuron denervation, offers high precision in monitoring drug effects on dysphagia-responsible bulbar muscles. This study paves the way for more humane and efficient approaches to developing treatment solutions for degenerative neuromuscular diseases.

Integrative Korean medicine treatment for inpatients with osteoarthritis of the knee: An observational study.

The use of integrative Korean medicine treatment (IKMT) for patients with knee osteoarthritis (OA) has been reported previously; however, to date, no studies have investigated the long-term prognosis of these patients following IKMT for primary knee OA. We aimed to examine the long-term effects of IKMT in patients diagnosed with primary knee OA and receiving IKMT during hospitalization. This retrospective observational study, complemented by a follow-up survey, included patients with primary knee OA who received IKMT during hospitalization across 7 Korean medicine hospitals. The primary outcome was the Numerical Rating Scale knee-pain score, whereas the secondary outcomes were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol-5 dimension-5 level questionnaire (EQ-5D-5L), and Patient Global Impression of Change scores. Patients were evaluated at admission, discharge, and during follow-up. Of the 180 included patients, 81 responded to the survey. Compared with the corresponding values at admission, the Numerical Rating Scale score decreased by 2.44 (2.08-2.81) points at discharge and 1.89 (1.5-2.26) points at follow-up. Additionally, compared with their scores at admission, the WOMAC score decreased by 17.20 (13.68-20.71) points at discharge and 25.74 (22.22-29.26) points at follow-up, whereas the EuroQol-5 dimension-5 level questionnaire score improved by -0.15 (-0.18 to -0.12) points at discharge and -0.12 (-0.15 to -0.09) points at follow-up. The patients expressed high satisfaction with pharmacopuncture (65.4%), acupuncture (54.03%), physical therapy (35.8%), and herbal medicine (34.6%). Regarding Patient Global Impression of Change, 96.30% of the patients reported improvement. IKMT was effective in improving pain, functional disability, and quality of life in patients with primary knee OA. Its effects were maintained throughout the long-term follow-up period, and physical functions continuously improved.

Raphanus sativus Linne Protects Human Nucleus Pulposus Cells against H2O2-Induced Damage by Inhibiting TREM2.

Intervertebral disc degeneration (IDD) progresses owing to damage and depletion of nucleus pulposus (NP) cells. Cytoprotection mitigates oxidative stress, nutrient deprivation, and mechanical stress, which lead to cell damage and necrosis. We aimed to examine the protective effect of Raphanus sativus Linne (RSL), common radish, against oxidative stress by H2O2 in human NP cells and whether the RSL extracts can inhibit triggering receptor expressed on myeloid cells 2 (TREM2), an inducer of apoptosis and degeneration in NP cells. We administered hydrogen peroxide (H2O2) to cultured human NP cells treated with RSL extracts. We used immunoblotting and quantitative PCR to investigate expression of the apoptosis-associated proteins in cultured cells. RSL significantly enhanced cell survival by suppressing the activation of cleaved caspase-3 and Bax. In contrast, RSL extract increased Bcl2 concentration to downregulate apoptosis. Additionally, RSL treatment notably enhanced the mRNA levels of ACAN and Col2a1 while significantly reducing those of ADAMTS-4, ADAMTS-5, MMP3, and MMP13, key genes involved in NP degeneration. While H2O2 elevated TREM2 expression, causing disc degeneration, RSL downregulated TREM2 expression. Thus, our findings imply that RSL supports human NP cells under oxidative stress and regulates the pathways underlying disc degeneration, particularly TREM2, and that RSL extracts may potentially prevent IDD.

Automatic Clinical Assessment of Swallowing Behavior and Diagnosis of Silent Aspiration Using Wireless Multimodal Wearable Electronics.

Dysphagia is more common in conditions such as stroke, Parkinson's disease, and head and neck cancer. This can lead to pneumonia, choking, malnutrition, and dehydration. Currently, the diagnostic gold standard uses radiologic imaging, the videofluoroscopic swallow study (VFSS); however, it is expensive and necessitates specialized facilities and trained personnel. Although several devices attempt to address the limitations, none offer the clinical-grade quality and accuracy of the VFSS. Here, this study reports a wireless multimodal wearable system with machine learning for automatic, accurate clinical assessment of swallowing behavior and diagnosis of silent aspirations from dysphagia patients. The device includes a kirigami-structured electrode that suppresses changes in skin contact impedance caused by movements and a microphone with a gel layer that effectively blocks external noise for measuring high-quality electromyograms and swallowing sounds. The deep learning algorithm offers the classification of swallowing patterns while diagnosing silent aspirations, with an accuracy of 89.47%. The demonstration with post-stroke patients captures the system's significance in measuring multiple physiological signals in real-time for detecting swallowing disorders, validated by comparing them with the VFSS. The multimodal electronics can ensure a promising future for dysphagia healthcare and rehabilitation therapy, providing an accurate, non-invasive alternative for monitoring swallowing and aspiration events.

All-in-One, Wireless, Multi-Sensor Integrated Athlete Health Monitor for Real-Time Continuous Detection of Dehydration and Physiological Stress.

Athletes are at high risk of dehydration, fatigue, and cardiac disorders due to extreme performance in often harsh environments. Despite advancements in sports training protocols, there is an urgent need for a non-invasive system capable of comprehensive health monitoring. Although a few existing wearables measure athlete's performance, they are limited by a single function, rigidity, bulkiness, and required straps and adhesives. Here, an all-in-one, multi-sensor integrated wearable system utilizing a set of nanomembrane soft sensors and electronics, enabling wireless, real-time, continuous monitoring of saliva osmolality, skin temperature, and heart functions is introduced. This system, using a soft patch and a sensor-integrated mouthguard, provides comprehensive monitoring of an athlete's hydration and physiological stress levels. A validation study in detecting real-time physiological levels shows the device's performance in capturing moments (400-500 s) of synchronized acute elevation in dehydration (350%) and physiological strain (175%) during field training sessions. Demonstration with a few human subjects highlights the system's capability to detect early signs of health abnormality, thus improving the healthcare of sports athletes.

Flexible Thermoelectric Wearable Architecture for Wireless Continuous Physiological Monitoring.

Continuous monitoring of physiological signals from the human body is critical in health monitoring, disease diagnosis, and therapeutics. Despite the needs, the existing wearable medical devices rely on either bulky wired systems or battery-powered devices needing frequent recharging. Here, we introduce a wearable, self-powered, thermoelectric flexible system architecture for wireless portable monitoring of physiological signals without recharging batteries. This system harvests an exceptionally high open circuit voltage of 175-180 mV from the human body, powering the wireless wearable bioelectronics to detect electrophysiological signals on the skin continuously. The thermoelectric system shows long-term stability in performance for 7 days with stable power management. Integrating screen printing, laser micromachining, and soft packaging technologies enables a multilayered, soft, wearable device to be mounted on any body part. The demonstration of the self-sustainable wearable system for detecting electromyograms and electrocardiograms captures the potential of the platform technology to offer various opportunities for continuous monitoring of biosignals, remote health monitoring, and automated disease diagnosis.

Trends of Korean medicine service utilization for lumbar disc herniation and spinal stenosis: A 10-year analysis of the 2010 to 2019 data.

This retrospective, cross-sectional, and descriptive study aimed to analyze the trend of utilizing traditional Korean medicine services in patients with lumbar disc herniation (LDH) and/or lumbar spinal stenosis (LSS). In this study, based on the national patient sample data provided by Health Insurance Review and Assessment Service (HIRA), the trend of Korean medicine service utilization was investigated, including the following information: demographic characteristics of the patients, the total expenditure, number of claim statements per category, medical care expenditure per category, and routes of visiting traditional Korean medicine institutions. The study population comprised patients who visited Korean medicine institutions at least once from January 2010 to December 2019, with LSS and LDH as the primary diagnosis. LDH patients who used traditional Korean medicine services for treatment increased by about 1.36 times. LDH and LSS patients under 45 years of age were more likely to be males, but women accounted for a higher percentage among those over 45 years of age. Overall, women accounted for a slightly higher percentage than their counterparts for both diseases. From details of treatments received that were extracted from the claims data, acupuncture treatment accounted for the highest percentage for both disorders. Moreover, 50.7% of the patients who visited Korean medicine institutions to treat the two diseases also visited conventional Western medicine institutions. These patients, who were diagnosed with their condition at a Korean medicine institution, visited a conventional institution and then returned; the conventional institutions were primarily used for examination (40.5%). Increased utilization of traditional Korean medicine services was confirmed among patients with LDH and/or LSS; in particular, a sharp increase was noted among patients with LSS. The results of this study will be useful as basic research data for clinicians, researchers, and policy makers.

Effectiveness and safety of motion-style acupuncture treatment using traction for inpatients with acute low back pain caused by a traffic accident: A randomized controlled trial.

BACKGROUND: Musculoskeletal symptoms, such as neck pain and low back pain (LBP) are common after a traffic accident (TA). While motion-style acupuncture treatment (MSAT) is effective in relieving pain, MSAT using traction (T-MSAT) has rarely been studied, and evidence for its efficacy and safety is lacking. To address this gap, this study aimed to assess the effectiveness and safety of T-MSAT for pain and functional disturbances in patients with acute LBP caused by a TA. METHODS: This two-armed, parallel, assessor blinded randomized controlled trial, conducted at Jaseng Hospital of Korean Medicine, included 100 patients with acute LBP occurring within 1 week of a TA. The participants were randomly allocated (1:1 ratio) to receive either combined T-MSAT and integrative Korean medicine treatment (IKMT) or only conventional IKMT, applied for 3 consecutive days after admission. The primary outcome was the difference between numerical rating scale (NRS) scores for LBP at baseline and after treatment completion on day 4 after admission. RESULTS: At the primary endpoint, the difference in NRS scores for LBP between the T-MSAT and control groups was 0.94 (95% confidence interval [CI] 0.40-1.48). The T-MSAT group showed a significantly lower NRS score for LBP than the control group. Differences in visual analogue scale (VAS) scores between the T-MSAT and control groups were significant at baseline and discharge. The area under the curve of the VAS score showed a significant difference (-46.86 [95% CI -85.13 to -8.59]), indicating faster pain reduction in the T-MSAT group than in the control group. Recovery (30% pain reduction) was achieved more rapidly in the T-MSAT group than in the control group (log-rank test P = .005). Meanwhile, the NRS, VAS, Oswestry disability index, and quality of life scores at discharge or at the 12-week follow-up showed no significant difference. The rates of mild adverse events (AEs) were comparable between the groups. No severe AEs were reported, and none of the AEs were associated with the clinical trial. CONCLUSIONS: T-MSAT combined with IKMT is a safe treatment that can effectively and quickly reduce initial pain in patients with LBP.

Repeated epidural delivery of Shinbaro2: effects on neural recovery, inflammation, and pain modulation in a rat model of lumbar spinal stenosis.

The choice of treatment for lumbar spinal stenosis (LSS) depends on symptom severity. When severe motor issues with urinary dysfunction are not present, conservative treatment is often considered to be the priority. One such conservative treatment is epidural injection, which is effective in alleviating inflammation and the pain caused by LSS-affected nerves. In this study, Shinbaro2 (Sh2), pharmacopuncture using natural herbal medicines for patients with disc diseases, is introduced as an epidural to treat LSS in a rat model. The treatment of primary sensory neurons from the rats' dorsal root ganglion (DRG) neurons with Sh2 at various concentrations (0.5, 1, and 2 mg/mL) was found to be safe and non-toxic. Furthermore, it remarkably stimulated axonal outgrowth even under H2O2-treated conditions, indicating its potential for stimulating nerve regeneration. When LSS rats received epidural injections of two different concentrations of Sh2 (1 and 2 mg/kg) once daily for 4 weeks, a significant reduction was seen in ED1+ macrophages surrounding the silicone block used for LSS induction. Moreover, epidural injection of Sh2 in the DRG led to a significant suppression of pain-related factors. Notably, Sh2 treatment resulted in improved locomotor recovery, as evaluated by the Basso, Beattie, and Bresnahan scale and the horizontal ladder test. Additionally, hind paw hypersensitivity, assessed using the Von Frey test, was reduced, and normal gait was restored. Our findings demonstrate that epidural Sh2 injection not only reduced inflammation but also improved locomotor function and pain in LSS model rats. Thus, Sh2 delivery via epidural injection has potential as an effective treatment option for LSS.

Improving Pain Self-Efficacy in Orthopedic Surgery Patients Through Video-Based Education: A Quality Improvement Project.

BACKGROUND: Effective pain management following discharge is critical for postoperative recovery, with pain self-efficacy serving as a crucial component in this process. Patient education plays a key role in enhancing self-efficacy. Among various educational modalities, a growing body of evidence supports the efficacy of video-based methods. LOCAL PROBLEM: A lack of evidence-based pain education programs for patients undergoing elective orthopedic surgery was identified at an urban academic hospital on the East Coast of the United States. This quality improvement project aimed to develop and assess a video-based pain education program, focusing on pain self-efficacy and self-reported preparedness among adult patients prescribed opioids for postsurgical pain. METHODS: This project adopted a pretest-posttest design, utilizing the knowledge-to-action framework. Data collection spanned 3 months. Among the 69 patients screened for eligibility, 13 participants were included in the analysis. The primary intervention consisted of a 15-minute educational video covering essential pain management aspects. Following the intervention, pain self-efficacy and self-reported preparedness were evaluated using the Pain Self-Efficacy Questionnaire and a five-point Likert scale, respectively. RESULTS: Median (IQR) scores on the Pain Self-Efficacy Questionnaire increased significantly from 20 (16) to 32 (14) (p < .01). Mean (SD) scores for patients' self-reported preparedness also increased from 21.92 (6.53) to 31.85 (2.41) (p < .01). All participants reported being satisfied or very satisfied with the educational intervention. CONCLUSION: Video-based education is a time-efficient and cost-effective approach. Healthcare providers can consider integrating video education to enhance pain self-efficacy in the postoperative phase, thus enhancing postsurgical pain outcomes and overall recovery experience.

Minimum clinically important difference and substantial clinical benefit in patients with chronic temporomandibular disorders.

BACKGROUND: Research on temporomandibular disorder (TMD) responsiveness is scarce and limited regarding patients' representativeness. OBJECTIVE(S): This study aimed to estimate minimum clinically important difference (MCID) and substantial clinical benefit (SCB) among a large and diverse patient population regarding sex and age. METHODS: In this study, 162 patients participated from five hospitals. MCID and SCB in pain, functional disability and quality of life were examined with anchor-based methods. Patients' global impression of change was used as the anchor. Area under the curve (AUC) values were determined for testing accuracy. Changes from baseline and coefficient of variation by responsiveness status were calculated to explain the results of accuracy. RESULTS: SCB was estimated to be 2.18 for the numeric rating scale (NRS) for pain (AUC: 0.80 [95% CI: 0.72-0.88]) in all patients and 2.50 in women (AUC: 0.81 [95% CI: 0.71-0.89]). The estimated SCB of NRS for discomfort (1.50) and Jaw Functional Limitation Scale for mastication (1.35) had wide CIs for AUCs. Likewise, the estimated MCIDs of NRS for pain (0.80) and NRS for discomfort (1.50) had wide CIs for AUCs. Among non-responders who did not achieve the MCID of NRS for pain, the coefficient of variation was very high for all outcomes other than the NRS for pain. CONCLUSION: This study investigated the responsiveness of patients with TMD using a large and diverse patient sample. SCB in pain decrease can be used to assess the responsiveness of patients with TMD. Composite outcomes should be developed to estimate MCID.

Health Care Utilization for Common Shoulder Disorders: Analysis of the 2010-2019 National Patient Sample Data from the Health Insurance Review and Assessment Service in Korea.

Background and Objective: The aim of this study was to analyze trends in surgical and non-surgical service utilization for common shoulder disorders in Korea from 2010 to 2019. Methods and Materials: This retrospective, cross-sectional, descriptive study utilized National Patient Sample data from the Health Insurance and Review Assessment Service (HIRA) of Korea. These data constitute a 2% sample out of the entire Korean population and include data for a variety of parameters instrumental for health care research. Patients with at least one medical service use for rotator cuff syndrome or tear, impingement syndrome, or adhesive capsulitis between January 2010 and December 2019 were included. Trends in healthcare utilization by disorder type, patient demographics, seasonal service use, and treatment details were examined. Results: There was an upward trend in the total number of patients and costs for shoulder disorders, from 35,798 patients and USD 5,485,196 in 2010 to 42,558 and USD 11,522,543 in 2019, respectively. The number of patients aged ≥60 and hospital visits increased. March had the highest number of claims. Physical therapy was the most common non-surgical procedure, while nerve block claims more than doubled. Opioid prescription rates also tripled. Surgical treatments were dominated by shoulder rotator cuff repair and acromioplasty. Conclusions: There was a significant increase in healthcare utilization for shoulder disorders, marked by rising costs and patient numbers. The use of nerve blocks and opioids notably increased. These data are valuable for clinicians, researchers, and policymakers.

Safety and effectiveness of integrative Korean medicine for the management of patients sustaining injuries in traffic accidents during pregnancy: A retrospective chart review and questionnaire survey.

The number of traffic accidents (TAs) is rising each year, and the severity of injuries can vary. Many people experience limitations in activities of daily living following TAs, affecting their quality of life. In pregnant women, even simple injuries caused by a TA could lead to unfavorable obstetric outcomes. Thus, we conducted a retrospective chart review and follow-up questionnaire survey to assess the safety and effectiveness of integrative Korean medicine (KM) treatment for pregnant women injured in TAs. To assess integrative KM effectiveness, the numeric rating scale (NRS) for TA-related symptoms, neck disability index (NDI) score, Oswestry disability index (ODI) score, shoulder pain and disability index score, Western Ontario and McMaster Universities Arthritis Index score, EuroQol 5-dimension 5-level (EQ-5D-5L) score, and patient global impression of change score were investigated for pregnant women injured in TAs. Additionally, for safety evaluation, obstetric and neonatal outcomes, as well as symptoms related to pregnancy, were assessed. At the end of treatment and follow-up, there were significant reductions in NDI and ODI scores, as well as NRS for neck pain, lower back pain, and headache, compared to scores at baseline. EQ-5D-5L scores significantly increased. A follow-up of 50 patients showed no major differences in obstetric and neonatal outcomes compared to the typical outcomes that occur in pregnant women and neonates. Major improvements were observed in the symptoms of patients who underwent integrative KM treatment after being injured in TAs. The symptoms occurred at a rate similar to those in typical pregnant women, while causality with integrative KM treatment was assessed to be unlikely or unclear. Therefore, integrative KM treatment may be considered an alternative treatment option for pregnant women who currently have limited treatment options.

Effectiveness and safety of hominis placental pharmacopuncture for chronic temporomandibular disorder: A multi-center randomized controlled trial.

Background: Hominis placental (HPP) extract has been approved by the Ministry of Food and Drug Safety in Korea for treating chronic liver diseases and postmenopausal syndrome. However, its efficacy and safety for treating chronic temporomandibular disorder (TMD) remains unclear. We aimed to assess the effectiveness and safety of HPP for treating chronic TMD compared with physical therapy (PT). Methods: This study is a 2-arm parallel, multi-center, randomized controlled trial. We enrolled 82 chronic TMD patients from 2 Korean medicine hospitals between December 2019 and January 2021. We included patients with chronic TMD and randomly assigned them to undergo HPP or PT. The primary outcome was the difference in the scores for temporomandibular joint (TMJ) pain at baseline and week 6. The secondary outcomes were the scores for TMJ pain and bothersomeness, TMJ range of motion, the Korean version of Beck's depression index-Ⅱ, jaw functional limitation scale (JFLS) score, patient global impression of change (PGIC) scores, EuroQoL 5-dimension 5-level score, and short form-12 health survey (SF-12) scores. Results: Compared with PT, HPP showed significantly superior effects on TMJ pain and bothersomeness, protrusive movement pain, JFLS (verbal, emotional, and global), SF-12, and PGIC scores at week 6 (P < 0.05). Compared with the PT group, the HPP group showed a significantly higher recovery rate (≥50 % reduction in the scores for TMJ pain at the 24-week follow-up). Conclusion: HPP was more effective than PT managing pain and improving function and quality of life. Our findings demonstrate the effectiveness and safety of HPP for TMD treatment. Trial registration: This study has been registered at clinicalTrials.gov (NCT04087005), Clinical Research Information Service (CRIS) (KCT0004437), and Ministry of Food and Drug Safety (No. 31886).
