| ○ | ○ | Article | Long-term clinical outcomes of image-guided percutaneous coronary intervention in acute myocardial infarction from the Korea Acute Myocardial Infarction Registry | Imaging modalities for percutaneous coronary intervention (PCI), such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT), have increased in the current PCI era. However, their clinical benefits in acute myocardial infarction (AMI) have not been fully elucidated. This study investigated the long-term outcomes of image-guided PCI in patients with AMI using data from the Korean Acute Myocardial Infarction Registry. A total of 9,271 patients with AMI, who underwent PCI with second-generation drug-eluting stents between November 2011 and December 2015, were retrospectively examined, and target lesion failure (TLF) at 3 years (defined as the composite of cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization) was evaluated. From the registry, 2,134 patients (23.0%) underwent image-guided PCI (IVUS-guided: n = 1,919 [20.6%]; OCT-guided: n = 215 patients [2.3%]). Based on propensity score matching, image-guided PCI was associated with a significant reduction in TLF (hazard ratio: 0.76; 95% confidence interval: 0.59-0.98, p = 0.035). In addition, the TLF incidence in the OCT-guided PCI group was comparable to that in the IVUS-guided PCI group (5.3% vs 4.7%, p = 0.903). Image-guided PCI, including IVUS and OCT, is associated with favorable clinical outcomes in patients with AMI at 3 years post-intervention. Additionally, OCT-guided PCI is not inferior to IVUS-guided PCI in patients with AMI. | Kwon, Youngjoon; Kim, Namkyun; Kim, Chang-Yeon; Kim, Do-Hoon; Shin, Hyewon; Jung, Min-Su; Park, Jong Sung; Park, Yoon Jung; Park, Bo Eun; Kim, Hong Nyun; Jang, Se Yong; Bae, Myung Hwan; Lee, Jang Hoon; Yang, Dong Heon; Park, Hun Sik; Cho, Yongkeun; Cha, Kwang Soo; Hur, Seung-Ho; Hwang, Jin-Yong; Jeong, Myung Ho | Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Daegu, South Korea; Daegu Catholic Univ, Sch Med, Dept Internal Med, Med Ctr, Daegu, South Korea; Eulji Univ, Daejeon Eulji Med Ctr, Dept Nucl Med, Sch Med, Daejeon, South Korea; Korea Univ, Coll Med, Dept Biostat, Seoul, South Korea; Lin Korea Co Ltd, Div Biostat, Seoul, South Korea; Pusan Natl Univ Hosp, Busan, South Korea; Keimyung Univ, Dongsan Med Ctr, Cardiovasc Med, Deagu, South Korea; Gyeonsang Natl Univ, Gyeongsang Natl Univ Hosp, Sch Med, Dept Internal Med, Jinju, South Korea; Chonnam Natl Univ Hosp, Gwangju, South Korea | ; Park, Hang-soo/AEH-1640-2022; Kim, Changyeon/AIC-3771-2022 | 57371880800; 55887032700; 55887435100; 55624468392; 59156145100; 57813643300; 58363053000; 57216539556; 57201131446; 56706769800; 57207977889; 36607356800; 54581258000; 35277423400; 57198844106; 9249593500; 7102837700; 34570274500; 55892914700; 56485157500 | namkyun.kim@knu.ac.kr;tinki804@naver.com; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 6 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0 | 2025-05-07 | 0 | 0 | ANGIOGRAPHY; ASSOCIATION; GUIDELINES; DOCUMENT | Aged; Drug-Eluting Stents; Female; Humans; Male; Middle Aged; Myocardial Infarction; Percutaneous Coronary Intervention; Registries; Republic of Korea; Retrospective Studies; Surgery, Computer-Assisted; Tomography, Optical Coherence; Treatment Outcome; Ultrasonography, Interventional; acetylsalicylic acid; clopidogrel; prasugrel; ticagrelor; drug eluting stent; acute heart infarction; adult; angiography; Article; body mass; clinical outcome; coronary angiography; coronary artery; coronary artery bypass graft; estimated glomerular filtration rate; female; follow up; heart death; heart left ventricle ejection fraction; human; imaging; incidence; Korea; left anterior descending coronary artery; male; middle aged; non ST segment elevation myocardial infarction; optical coherence tomography; percutaneous coronary intervention; retrospective study; revascularization; right coronary artery; ST segment elevation myocardial infarction; target lesion revascularization; target vessel revascularization; thrombus aspiration; aged; computer assisted surgery; diagnostic imaging; epidemiology; heart infarction; interventional ultrasonography; optical coherence tomography; procedures; register; South Korea; surgery; therapy; treatment outcome | English | 2024 | 2024-06-05 | 10.1371/journal.pone.0304843 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Psychometric properties and measurement invariance of the short form of grit scale in Korean adolescents | This study aimed to identify the factor structure of the Korean version of the Short Grit Scale (Grit-S) and examine its cross-sectional and longitudinal measurement invariance (MI). Data from the Korean Children and Youth Panel Survey 2018 were analyzed, which included two cohorts, comprising 2,327 and 2,325 fourth-year elementary and first-year middle school students, respectively. It was found that the two-factor model fit the data well for the elementary and middle school samples. The results of the cross-sectional MI tests across genders indicated that the full threshold and loading invariance were also supported for the elementary school sample, and the partial threshold and loading invariance were supported for the middle school sample. The analyses of the longitudinal MI revealed that the partial threshold and loading invariance were supported for both samples. The reliability analysis revealed satisfactory McDonald's Omega values for both samples at each time point and moderate stability coefficients over time. Based on these findings, it was concluded that the Korean version of the Grit-S demonstrated satisfactory psychometric properties and exhibited MI across gender and time in Korean adolescents. | Bae, Sung-Woo; Kim, Ji Geun; Park, Byung-Sun; Lee, Keungeun; Park, Jungkyu | Kyungpook Natl Univ, Div Social Welf, Daegu, South Korea; Kyungpook Natl Univ, Dept Psychol, Daegu 41566, South Korea; Gangneung Wonju Natl Univ, Dept Social Welf, Wonju, Gangwon State, South Korea | Ashraf, Syed Amir/AAY-2793-2020 | 7202714623; 57205490385; 57867167100; 57866974100; 56206565000 | jkp@knu.ac.kr;keung@knu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 1 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.92 | 2025-04-16 | 2 | 2 | FACTORIAL INVARIANCE; MODEL; SELF; SATISFACTION; PERSEVERANCE; PERSONALITY; NEEDS | Adolescent; Child; Cross-Sectional Studies; Female; Humans; Male; Psychometrics; Reproducibility of Results; Republic of Korea; Surveys and Questionnaires; adolescent; article; child; cross-sectional study; diagnosis; female; human; longitudinal study; male; middle school; middle school student; primary school; reliability; cross-sectional study; procedures; psychometry; questionnaire; reproducibility; South Korea | English | 2024 | 2024-01-19 | 10.1371/journal.pone.0296795 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Similar recurrence after curative treatment of HBV-related HCC, regardless of HBV replication activity | Background and aims Antiviral therapy (AVT) is required in patients with newly diagnosed hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC), if HBV DNA is detectable. We compared the risk of recurrence according to HBV replication activity at the curative treatment of HBV-related HCC. Methods Patients with HBV-related HCC who underwent surgical resection or radiofrequency ablation between 2013 and 2018 were enrolled in this retrospective cohort study. Patients were categorized into two groups according to HBV replication activity at the curative treatment of HBV-related HCC (group 1: patients who met the AVT indication for HBV-related HCC due to detectable HBV DNA but did not meet the AVT indication if without HCC; group 2: patients who met the AVT indication, regardless of HCC). Results In the entire cohort (n = 911), HCC recurred in 303 (33.3%) patients during a median follow-up of 4.7 years. After multivariate adjustment, group 2 showed a statistically similar risk of HCC recurrence (adjusted hazard ratio [aHR] = 1.18, P = 0.332) compared to that of group 1. In addition, group 2 showed statistically similar risks of early (= 2 years; aHR = 0.83) recurrence than that of group 1 (all P>0.05). Propensity score matching and inverse probability of treatment weighting analysis also yielded similar risks of HCC recurrence between the two groups (all P>0.05, log-rank tests). Conclusions The risk of HCC recurrence in patients who received curative treatment for newly diagnosed HBV-related HCC was similar regardless of HBV replication activity, if AVT was properly initiated. | Kim, Mi Na; Kim, Beom Kyung; Cho, Heejin; Goh, Myung Ji; Roh, Yun Ho; Yu, Su Jong; Sinn, Dong Hyun; Park, Soo Young; Kim, Seung Up | Yonsei Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Yonsei Univ, Coll Med, Inst Gastroenterol, Seoul, South Korea; Severance Hosp, Yonsei Liver Ctr, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Seoul Natl Univ, Liver Res Inst, Coll Med, Seoul, South Korea; Sungkyunkwan Univ, Sch Med, Samsung Med Ctr, Dept Med, Seoul, South Korea; Yonsei Univ, Coll Med, Dept Biomed Syst Informat, Biostat Collaborat Unit, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea | ; Sinn, Dong/JAC-4247-2023; Kim, Sun/L-4239-2013; Kim, Young/T-8521-2019; Kim, Nayoung/J-5387-2012 | 57202910894; 58423843500; 57355533800; 57215026475; 56516260000; 7405730251; 23493891100; 57191674344; 54933821200 | ksukorea@yuhs.ac;psyoung041@gmail.com;dh.sinn@samsung.com;sujongyu@gmail.com; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 8 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0 | 2025-05-07 | 0 | 0 | HEPATOCELLULAR-CARCINOMA RECURRENCE; CLINICAL-PRACTICE GUIDELINES; HIGH VIRAL LOAD; HEPATITIS-B; ANTIVIRAL THERAPY; INTRAHEPATIC RECURRENCE; RADIOFREQUENCY ABLATION; RISK-FACTORS; RESECTION; SURVIVAL | Aged; Antiviral Agents; Carcinoma, Hepatocellular; DNA, Viral; Female; Hepatitis B; Hepatitis B virus; Humans; Liver Neoplasms; Male; Middle Aged; Neoplasm Recurrence, Local; Retrospective Studies; Virus Replication; alanine aminotransferase; aspartate aminotransferase; bilirubin; entecavir; hepatitis B(e) antigen; lamivudine; tenofovir; tenofovir disoproxil; warfarin; antivirus agent; virus DNA; adult; alcohol consumption; antiviral therapy; Article; body mass; cancer recurrence; cancer staging; chemoembolization; Child Pugh score; chronic hepatitis B; cohort analysis; coinfection; computer assisted tomography; controlled study; diabetes mellitus; drug therapy; follow up; hepatitis B; Hepatitis B virus; human; hypertension; in situ hybridization; liver cell carcinoma; liver cirrhosis; liver function test; major clinical study; male; metatarsophalangeal joint; middle aged; Model For End Stage Liver Disease Score; nuclear magnetic resonance imaging; platelet count; probability; propensity score; prospective study; prothrombin time; radiofrequency ablation; recurrence risk; recurrent disease; replication study; risk factor; scientific literature; tea; thyroxine blood level; treatment response; tumor volume; aged; complication; female; genetics; hepatitis B; Hepatitis B virus; liver cell carcinoma; liver tumor; pathology; physiology; retrospective study; tumor recurrence; virology; virus replication | English | 2024 | 2024-08-26 | 10.1371/journal.pone.0307712 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Simulation design to find the welfare impacts of livestock trading and disease transmission | This study designs a theoretical model and simulation model that can explain the welfare impacts of disease transmission that occurs in livestock trade. A household production model and a SIR model are used to find theoretical profitable conditions for infectious livestock trading and prices and quantities for transactions. Under the theoretical conditions an agent-based model is used to simulate livestock transactions to compare social impacts based on the number of livestock, household wealth and income, and wealth inequality. Asymmetric information is used to assign tendencies of livestock trading agents. Buyers are assumed to be uninformed about the health status of livestock owned or used by sellers, while sellers are either uninformed for their herd's health status, and if informed, the sellers' behavior of selecting infectious livestock for transactions is divided into selfish selection and altruistic selection. The simulation results reveal that livestock losses are higher when trading occurs, but overall economic welfare tends to increase with trade. Interestingly, when sellers selfishly sell sick animals, average household wealth and income peak, albeit with greater wealth inequality. | Hwang, Hyeonjun | Kyungpook Natl Univ, Grad Sch Data Sci, Daegu, South Korea | 57202335911 | hhwang@knu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 11 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0 | 2025-05-07 | 0 | 0 | SOCIAL NETWORK ANALYSIS; MOUTH-DISEASE; INFECTIOUS-DISEASES; ANIMAL MOVEMENTS; ECONOMICS; SPREAD; CATTLE; MARKET; INCENTIVES; GERMANY | Animal Welfare; Animals; Commerce; Computer Simulation; Humans; Livestock; Models, Economic; Models, Theoretical; Article; disease transmission; epidemic; health status; high myopia; household; information asymmetry; livestock; mortality rate; nonhuman; population size; prevalence; vaccination; virus transmission; wealth inequality; animal; animal welfare; commercial phenomena; computer simulation; economic model; human; theoretical model | English | 2024 | 2024-11-20 | 10.1371/journal.pone.0310213 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | The utility of intraoperative ultrasonography for spinal cord surgery | Objectives Intraoperative ultrasonography (IOUS) offers the advantage of providing real-time imaging features, yet it is not generally used. This study aims to discuss the benefits of utilizing IOUS in spinal cord surgery and review related literature.Materials and methods Patients who underwent spinal cord surgery utilizing IOUS at a single institution were retrospectively collected and analyzed to evaluate the benefits derived from the use of IOUS.Results A total of 43 consecutive patients were analyzed. Schwannoma was the most common tumor (35%), followed by cavernous angioma (23%) and ependymoma (16%). IOUS confirmed tumor extent and location before dura opening in 42 patients (97.7%). It was particularly helpful for myelotomy in deep-seated intramedullary lesions to minimize neural injury in 13 patients (31.0% of 42 patients). IOUS also detected residual or hidden lesions in 3 patients (7.0%) and verified the absence of hematoma post-tumor removal in 23 patients (53.5%). In 3 patients (7.0%), confirming no intradural lesions after removing extradural tumors avoided additional dural incisions. IOUS identified surrounding blood vessels and detected dural defects in one patient (2.3%) respectively.Conclusions The IOUS can be a valuable tool for spinal cord surgery in identifying the exact location of the pathologic lesions, confirming the completeness of surgery, and minimizing the risk of neural and vascular injury in a real-time fashion. | Park, Hangeul; Kim, Jun-Hoe; Lee, Chang-Hyun; Kim, Sum; Kim, Young-Rak; Kim, Kyung-Tae; Kim, Ji-hoon; Rhee, John M.; Jo, Woo-Young; Oh, Hyongmin; Park, Hee-Pyoung; Kim, Chi Heon | Seoul Natl Univ Hosp, Dept Neurosurg, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Neurosurg, Seoul, South Korea; Hallym Univ, Kandong Sacred Heart Hosp, Coll Med, Dept Neurosurg, Seoul, South Korea; Armed Forces Yangju Hosp, Dept Neurosurg, Yangu, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Chilgok Hosp, Sch Med, Dept Neurosurg, Daegu, South Korea; Seoul Natl Univ, Seoul Natl Univ Hosp, Coll Med, Dept Radiol, Seoul, South Korea; Emory Univ, Sch Med, Dept Orthopaed Surg, Atlanta, GA USA; Seoul Natl Univ Hosp, Dept Anesthesiol & Pain Med, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Anesthesiol & Pain Med, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Med Device Dev, Seoul, South Korea | ; Park, Hee/J-5500-2012; Kim, Chi/J-6536-2019; Kim, Ji-Hoon/HZJ-6703-2023 | 57221731362; 57854370000; 56942572100; 58609171200; 57222335356; 59444181600; 58836440300; 7202839338; 57195596146; 55908926200; 15758312400; 35145892000 | chiheon1@snu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 7 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.82 | 2025-05-07 | 2 | 2 | ULTRASOUND; INTRAMEDULLARY; TUMOR; SONOGRAPHY; OUTCOMES | Adolescent; Adult; Aged; Child; Ependymoma; Female; Humans; Male; Middle Aged; Neurilemmoma; Neurosurgical Procedures; Retrospective Studies; Spinal Cord; Spinal Cord Neoplasms; Ultrasonography; Young Adult; adult; arachnoid cyst; Article; blood vessel injury; cavernous hemangioma; cerebrospinal fluid; clinical article; clinical outcome; cordotomy (spinal cord); disease assessment; ependymoma; European Quality of Life 5 Dimensions questionnaire; female; follow up; gait; glioma; gross total resection; hemangioblastoma; hematoma; hospital discharge; hospitalization; human; laminectomy; length of stay; male; medical procedures; middle aged; modified McCormick scale; motor evoked potential; nerve injury; neurilemoma; nuclear magnetic resonance imaging; operation duration; peroperative echography; retrospective study; sensory dysfunction; solitary fibrous tumor; spinal cord surgery; subependymoma; adolescent; adverse event; aged; child; diagnostic imaging; echography; ependymoma; neurilemoma; neurosurgery; procedures; spinal cord; spinal cord tumor; surgery; young adult | English | 2024 | 2024-07-10 | 10.1371/journal.pone.0305694 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Trends in degenerative lumbar spinal surgery during the early COVID-19 pandemic in Republic of Korea: A national study utilizing the national health insurance database | During the first year of the COVID-19 pandemic, the Republic of Korea (ROK) experienced three epidemic waves in February, August, and November 2020. These waves, combined with the overarching pandemic, significantly influenced trends in spinal surgery. This study aimed to investigate the trends in degenerative lumbar spinal surgery in ROK during the early COVID-19 pandemic, especially in relation to specific epidemic waves. Using the National Health Information Database in ROK, we identified all patients who underwent surgery for degenerative lumbar spinal diseases between January 1, 2019 and December 31, 2020. A joinpoint regression was used to assess temporal trends in spinal surgeries over the first year of the COVID-19 pandemic. The number of surgeries decreased following the first and second epidemic waves (p<0.01 and p = 0.34, respectively), but these were offset by compensatory increases later on (p<0.01 and p = 0.05, respectively). However, the third epidemic wave did not lead to a decrease in surgical volume, and the total number of surgeries remained comparable to the period before the pandemic. When compared to the pre-COVID-19 period, average LOH was reduced by 1 day during the COVID-19 period (p<0.01), while mean hospital costs increased significantly from 3,511 to 4,061 USD (p<0.01). Additionally, the transfer rate and the 30-day readmission rate significantly decreased (both p<0.01), while the reoperation rate remained stable (p = 0.36). Despite the impact of epidemic waves on monthly surgery numbers, a subsequent compensatory increase was observed, indicating that surgical care has adapted to the challenges of the pandemic. This adaptability, along with the stable total number of operations, highlights the potential for healthcare systems to continue elective spine surgery during public health crises with strategic resource allocation and patient triage. Policies should ensure that surgeries for degenerative spinal diseases, particularly those not requiring urgent care but crucial for patient quality of life, are not unnecessarily halted. | Yuh, Woon Tak; Kim, Jinhee; Kim, Mi-Sook; Kim, Jun-Hoe; Kim, Young Rak; Kim, Sum; Chung, Chun Kee; Lee, Chang-Hyun; Park, Sung Bae; Kim, Kyoung-Tae; Rhee, John M.; Ko, Young San; Kim, Chi Heon | Hallym Univ, Coll Med, Dept Neurosurg, Chunchon Si, Gangwon Do, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Dept Neurosurg, Hwaseong Si, Gyeonggi Do, South Korea; Seoul Natl Univ Hosp, Med Res Collaborating Ctr, Div Clin Epidemiol, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Prevent Med, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Neurosurg, Seoul, South Korea; Seoul Natl Univ, Coll Med, Dept Neurosurg, Seoul, South Korea; Seoul Natl Univ, Dept Brain & Cognit Sci, Seoul, South Korea; Seoul Natl Univ, Boramae Hosp, Dept Neurosurg, Boramae Med Ctr, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Korea Univ, Guro Hosp, Coll Med, Dept Neurosurg, Seoul, South Korea; Emory Univ, Sch Med, Dept Orthopaed Surg, Atlanta, GA USA; Seoul Natl Univ, Coll Med, Dept Med Device Dev, Seoul, South Korea | ; Chung, Chun Kee/J-5650-2012; Kim, Chi/J-6536-2019; Chung, Chun/J-5650-2012 | 57191359268; 59291675100; 56376012200; 57854370000; 57222335356; 58609171200; 57222878160; 56942572100; 45261436700; 57201369790; 7202839338; 57767618800; 35145892000 | chiheon1@snu.ac.kr; | PLOS ONE | PLOS ONE | 1932-6203 | 19 | 6 | SCIE | MULTIDISCIPLINARY SCIENCES | 2024 | 2.6 | 32.2 | 0.41 | 2025-05-07 | 0 | 1 | REOPERATION RATE; STENOSIS; COMPLICATIONS; DECOMPRESSION; FUTURE; INDEX; STAY; 1ST | Adult; Aged; COVID-19; Databases, Factual; Female; Humans; Lumbar Vertebrae; Male; Middle Aged; National Health Programs; Pandemics; Republic of Korea; SARS-CoV-2; Spinal Diseases; adult; aged; Article; Charlson Comorbidity Index; cohort analysis; coronavirus disease 2019; decompression surgery; degenerative lumbar spinal surgery; epidemic; female; health care cost; health care delivery; health care system; hospitalization; human; ICD-10; intervertebral disk hernia; length of stay; lumbar spinal stenosis; major clinical study; male; national health insurance; outcome assessment; pandemic; patient triage; public health; reoperation; resource allocation; spinal cord surgery; spondylolisthesis; spondylolysis; surgical volume; trend study; very elderly; epidemiology; factual database; lumbar vertebra; middle aged; pandemic; Severe acute respiratory syndrome coronavirus 2; South Korea; spine disease; surgery | English | 2024 | 2024-06-11 | 10.1371/journal.pone.0305128 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Very early vs delayed invasive strategy in high-risk NSTEMI patients without hemodynamic instability: Insight from the KAMIR-NIH | Background High-risk non-ST-elevation myocardial infarction (NSTEMI) patients’ optimal timing for percutaneous coronary intervention (PCI) is debated despite the recommendation for early invasive revascularization. This study aimed to compare outcomes of NSTEMI patients without hemodynamic instability undergoing very early invasive strategy (VEIS, ≤ 12 hours) versus delayed invasive strategy (DIS, >12 hours). Methods Excluding urgent indications for PCI including initial systolic blood pressure under 90 mmHg, ventricular arrhythmia, or Killip class IV, 4,733 NSTEMI patients were recruited from the Korea Acute Myocardial Infarction Registry-National Institutes of Health (KAMIR-NIH). Patients were divided into low and high- global registry of acute coronary events risk score risk score (GRS) groups based on 140. Both groups were then categorized into VEIS and DIS. Clinical outcomes, including all-cause death (ACD), cardiac death (CD), recurrent MI, and cerebrovascular accident at 12 months, were evaluated. Results Among 4,733 NSTEMI patients, 62% had low GRS, and 38% had high GRS. The proportions of VEIS and DIS were 43% vs. 57% in the low GRS group and 47% vs. 53% in the high GRS group. In the low GRS group, VEIS and DIS demonstrated similar outcomes; however, in the high GRS group, VEIS exhibited worse ACD outcomes compared to DIS (HR = 1.46, P = 0.003). The adverse effect of VEIS was consistent with propensity score matched analysis (HR = 1.34, P = 0.042). Conclusion VEIS yielded worse outcomes than DIS in high-risk NSTEMI patients without hemodynamic instability in real-world practice. Copyright: © 2024 Lee et al.

| ○ | ○ | Article | Accuracy of posteroanterior cephalogram landmarks and measurements identification using a cascaded convolutional neural network algorithm: A multicenter study | Objective: To quantify the effects of midline-related landmark identification on midline deviation measurements in posteroanterior (PA) cephalograms using a cascaded convolutional neural network (CNN). Methods: A total of 2,903 PA cephalogram images obtained from 9 university hospitals were divided into training, internal validation, and test sets (n = 2,150, 376, and 377). As the gold standard, 2 orthodontic professors marked the bilateral landmarks, including the frontozygomatic suture point and latero-orbitale (LO), and the midline landmarks, including the crista galli, anterior nasal spine (ANS), upper dental midpoint (UDM), lower dental midpoint (LDM), and menton (Me). For the test, Examiner -1 and Examiner -2 (3 -year and 1 -year orthodontic residents) and the Cascaded -CNN models marked the landmarks. After point-to-point errors of landmark identification, the successful detection rate (SDR) and distance and direction of the midline landmark deviation from the midsagittal line (ANS -mid, UDM-mid, LDM-mid, and Me -mid) were measured, and statistical analysis was performed. Results: The cascaded -CNN algorithm showed a clinically acceptable level of point-to-point error (1.26 mm vs. 1.57 mm in Examiner -1 and 1.75 mm in Examiner -2). The average SDR within the 2 mm range was 83.2%, with high accuracy at the LO (right, 96.9%; left, 97.1%), and UDM (96.9%). The absolute measurement errors were less than 1 mm for ANSmid, UDM-mid, and LDM-mid compared with the gold standard. Conclusions: The cascaded -CNN model may be considered an effective tool for the auto -identification of midline landmarks and quantification of midline deviation in PA cephalograms of adult patients, regardless of variations in the image acquisition method. | Han, Sung-Hoon; Lim, Jisup; Kim, Jun-Sik; Cho, Jin-Hyoung; Hong, Mihee; Kim, Minji; Kim, Su -Jung; Kim, Yoon-Ji; Kim, Young Ho; Lim, Sung-Hoon; Sung, Sang Jin; Kang, Kyung-Hwa; Baek, Seung-Hak; Choi, Sung -Kwon; Kim, Namkug | Catholic Univ Korea, Seoul St Marys Hosp, Coll Med, Dept Orthodont, Seoul, South Korea; Univ Ulsan, Asan Med Inst Convergence Sci & Technol, Asan Med Ctr, Dept Convergence Med,Coll Med, 88 Olymp Ro 43 Gil, Seoul 05505, South Korea; Chonnam Natl Univ, Sch Dent, Dept Orthodont, Gwangju, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea; Ewha Womans Univ, Coll Med, Dept Orthodont, Seoul, South Korea; Kyung Hee Univ, Sch Dent, Dept Orthodont, Seoul, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Orthodont, Seoul, South Korea; Ajou Univ, Sch Med, Inst Oral Hlth Sci, Dept Orthodont, Suwon, South Korea; Chosun Univ, Coll Dent, Dept Orthodont, Gwangju, South Korea; Wonkwang Univ, Sch Dent, Dept Orthodont, 460 Iksan Daero, Iksan 54538, South Korea; Seoul Natl Univ, Dent Res Inst, Sch Dent, Dept Orthodont, Seoul, South Korea | kim, minji/GRX-9996-2022; Sung, Sang Jin/KBQ-4217-2024; Kim, Jun/AAA-8565-2019; Kim, Namkug/E-3843-2012; KIM, SUHWAN/GSE-0120-2022; Baek, Seung-Hak/NOE-8444-2025 | 55902078300; 58867113700; 57837493800; 15764519700; 57190379016; 57201330607; 57039799500; 57221435554; 57207443980; 36793499100; 7202731963; 35285868600; 35090967400; 57212023246; 16550058300 | chsk6206@wku.ac.kr;namkugkim@gmail.com; | KOREAN JOURNAL OF ORTHODONTICS | KOREAN J ORTHOD | 2234-7518 | 2005-372X | 54 | 1 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 2.3 | 32.4 | 1.12 | 2025-04-16 | 1 | 1 | Artificial intelligence; Convolutional neural network; Posteroanterior cephalograms | ARTIFICIAL-INTELLIGENCE | Artificial intelligence; Convolutional neural network; Posteroanterior cephalograms | English | 2024 | 2024-01 | 10.4041/kjod23.075 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Botulinum toxin type A is a potential therapeutic drug for chronic orofacial pain | Background: Botulinum toxin type A (BTX-A), produced by the gram-positive anaerobic bacterium Clostridium botulinum, acts by cleaving synaptosome-associated protein-25 (SNAP-25), an essential component of the presynaptic neuronal membrane that is necessary for fusion with the membrane proteins of neurotransmittercontaining vesicles. Recent studies have highlighted the efficacy of BTX-A in treating chronic pain conditions, including lower back pain, chronic neck pain, neuropathic pain, and trigeminal neuralgia, particularly when patients are unresponsive to traditional painkillers. This review focuses on the analgesic effects of BTX-A in various chronic pain conditions, with a particular emphasis on the orofacial region. Highlight: This review focuses on the mechanisms by which BTX-A induces analgesia in patients with inflammatory and temporomandibular joint pain. This review also highlights the fact that BTX-A can effectively manage neuropathic pain and trigeminal neuralgia, which are difficult-to-treat chronic pain conditions. Herein, we present a comprehensive assessment of the central analgesic effects of BTX-A and a discussion of its various applications in clinical dental practice. Conclusion: BTX-A is an approved treatment option for various chronic pain conditions. Although there is evidence of axonal transport of BTX-A from peripheral to central endings in motor neurons, the precise mechanism underlying its pain-modulating effects remains unclear. This review discusses the evidence supporting the effectiveness of BTX-A in controlling chronic pain conditions in the orofacial region. BTX-A is a promising therapeutic agent for treating pain conditions that do not respond to conventional analgesics. | Kim, Yu-Mi; Son, Jo-Young; Ahn, Dong-Kuk | Kyungpook Natl Univ, Sch Dent, Dept Oral Physiol, 2177 Dalgubeol Daero, Taegu 41940, South Korea | ; Kim, Yu-Mi/AAU-5083-2021 | 57816812300; 57201998311; 7202706889 | dkahn@knu.ac.kr; | JOURNAL OF ORAL BIOSCIENCES | J ORAL BIOSCI | 1349-0079 | 1880-3865 | 66 | 3 | ESCI | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 2.3 | 32.4 | 0.91 | 2025-05-07 | 3 | 4 | Botulinum toxin type A; Chronic pain; Temporomandibular joint dysfunction; syndrome; Neuropathic pain; Trigeminal neuralgia | NEUROTOXIN TYPE-A; SPINAL-CORD-INJURY; CENTRAL ANTINOCICEPTIVE ACTIVITY; CAPSAICIN-EVOKED PAIN; NEUROPATHIC PAIN; TRIGEMINAL NERVE; RAT MODEL; INFRAORBITAL NERVE; RECEPTOR EXPRESSION; CONSTRICTION INJURY | Botulinum toxin type A; Chronic pain; Neuropathic pain; Temporomandibular joint dysfunction syndrome; Trigeminal neuralgia | Botulinum Toxins, Type A; Chronic Pain; Facial Pain; Humans; analgesic agent; botulinum toxin A; synaptosomal associated protein 25; botulinum toxin A; adverse drug reaction; analgesia; analgesic activity; chronic pain; Clostridium botulinum; dental practice; drug therapy; human; low back pain; motoneuron; neck pain; nerve cell membrane; nerve fiber transport; nerve membrane; neuropathic pain; nonhuman; pain; review; side effect; synaptosome; temporomandibular joint disorder; therapy; trigeminus neuralgia; face pain | English | 2024 | 2024-09 | 10.1016/j.job.2024.06.004 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | Article | Effectiveness of virtual reality interactive simulation practice in prosthodontic education: A systematic review and meta-analysis | Introduction: Virtual reality-based interactive simulation (VRIS) provides a safe and controlled environment for dental students and professionals to develop skills and knowledge. This study aimed to investigate the effectiveness of using the VRIS for prosthodontic practice and to explore the trends, application areas, and users' attitudes towards VRIS. Materials and Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for searching studies published until 21 March 2023 that reported quantitative or qualitative learning outcomes related to the use of VRIS for dental prosthodontic practice and clinical training. The quality of the included studies was assessed using the Medical Education Research Study Quality Instrument (MERSQI) and Newcastle–Ottawa Scale-Education (NOS-E) tools. A random-effects meta-analysis was conducted to compare the intervention group (utilizing VRIS) and the control group (employing conventional prosthodontic training methods) based on performance skill scores and task completion time, with a significance level set at 50%; p =.13) and reduces task completion time (SMD = −0.03; 95% CI, 1.39–7.72; I2 > 50%; p =.93). Notably, using VRIS significantly enhanced the performance scores in implant surgery practice (SMD = 0.26; 95% CI, 0.09–0.42; p <.05). Additionally, the VRIS method significantly reduced task completion time in the cavity restorative preparation task (SMD = −1.19; 95% CI, −1.85 to −0.53; p <.05). Conclusion: Engaging in practice with VRIS has the potential to enhance learning proficiency in prosthodontic education. The advantages associated with VRIS encompass the provision of immediate feedback, decreased task completion time, heightened confidence and motivation, accelerated skill acquisition, improved performance scores, and increased learning engagement. © 2024 John Wiley & Sons A/S.

| ○ | ○ | Article | Preliminary study of environmental risk and protective factors during pregnancy for cleft lip with or without palate in the Korean population | Objective: To investigate which types of environmental exposure during pregnancy are risk and protective factors for cleft lip with or without cleft palate (CL/P). Methods: This case-control study included 278 orthodontic patients with CL/P (CL/P group) and 51 without CL/P (non-CL/P group). Demographic and environmental exposure data were collected using questionnaires completed by the parents. Statistical analyses were performed to identify the potential risk and protective factors for CL/P. Results: The two groups did not show significant difference in (1) body weight at birth and number of previous births; (2) fathers' ages at birth and occupation; (3) parents' chronic diseases, alcohol consumption, and exposure to harmful substances; and (4) mothers' smoking, secondhand smoking, and vitamin and calcium intake. Most patients with CL/ P were born at normal term (>= 37 weeks, 93.2%) with normal body weight (2.9-3.7 kg, 63.7%) and as either the first or second child (90.3%). In the CL/ P group, the percentages of mothers who were very young or old (= 40 years) and with physical labor in their occupation were low (1.8% and 2.2%, respectively). Compared with the non-CL/P group, the CL/P group showed a lower percentage of maternal folic acid intake (68.6% vs. 20.9%, odds ratio [OR] = 0.121; P < 0.001) and higher percentages of mothers' drug intake and fathers' smoking habits (3.9% vs. 16.2%, OR = 4.73, P < 0.05; 39.2% vs. 61.2%, OR = 2.44, P < 0.01). Conclusions: The findings of this study may explain the association between environmental factors and CL/P risk. | Kang, Min-Jeong; Li, Nang Paung; Hong, Hyunseung; Park, Hyo-Sang; Park, Ji Wan; Tolarova, Marie M.; Yang, Il-Hyung; Hong, Mihee; Baek, Seung-Hak | Kyungpook Natl Univ, Sch Dent, Dept Orthodont, Daegu, South Korea; Seoul Natl Univ, Sch Dent, Dept Orthodont, Seoul, South Korea; Hallym Univ, Coll Med, Dept Med Genet, Chunchon, South Korea; Univ Pacific, Arthur A Dugoni Sch Dent, Dept Orthodont, San Francisco, CA USA; Seoul Natl Univ, Dent Res Inst, Sch Dent, Dept Orthodont, 101 Daehak Ro, Seoul 03080, South Korea; Kyungpook Natl Univ, Translat Res Dent, Sch Dent, Dept Orthodont, 2175 Dalgubeol Daero, Daegu 41940, South Korea | ; Baek, Seung-Hak/NOE-8444-2025 | 59454290200; 59453502000; 57850988600; 55754836800; 57206479020; 7003885105; 23468146600; 57190379016; 35090967400 | mhhong1208@gmail.com;drwhite@snu.ac.kr; | KOREAN JOURNAL OF ORTHODONTICS | KOREAN J ORTHOD | 2234-7518 | 2005-372X | 54 | 6 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2024 | 2.3 | 32.4 | 0 | 2025-05-07 | 0 | 0 | CL/P; Environmental factor; Folic acid intake; Smoking | CONGENITAL-MALFORMATIONS; ALCOHOL-CONSUMPTION; DIABETES-MELLITUS; OROFACIAL CLEFTS; FOLIC-ACID; ASSOCIATION; PREVALENCE; INFANTS; WOMEN | CL/P; Environmental factor; Folic acid intake; Smoking | English | 2024 | 2024-11 | 10.4041/kjod24.137 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Resonant mode calculation method for extremely large-scale optical ring resonators | To analyze the resonant modes of optical devices such as optical gyro-sensors and semiconductor lasers, Maxwell's equations need to be solved. Widely used numerical methods are the finite element method (FEM) and the finite-difference time-domain (FDTD) method. However, when optical systems are significantly larger than the operating wavelength, applying these methods becomes practically infeasible due to the exponential increase in computational resources and simulation time. In this study, we propose a novel FDTD-based method to obtain the optical modes of large-scale optical systems, by setting the calculation area as the region where most of the light field is formed, dividing it into computationally feasible subdomains, and sequentially compute the field along the direction of light propagation. We have verified the proposed method by applying it to the calculation of resonant modes of 3-mirror ring resonators, which are used in ring laser gyro-sensors. In solving this problem, we also utilize transformation optics so that a non-rectangular subdomain is mapped to the rectangular-shaped subdomain with spatially varying refractive index distribution. Our method is expected to be useful for the improvement of device performance in large-scale optical systems in which the electromagnetic field propagates mainly around a simple closed path.

| ○ | ○ | Article | Adsorptive removal of nerve gas via activated carbon fiber: Precursor and fabric structure effects | Activated carbon fibers (ACFs) are extensively used to adsorb chemical warfare agents, including nerve agents. Cellulose-based materials are attractive precursors due to their low cost and abundant availability. However, the influence of the precursor material and fabric structure on the adsorption efficiency of ACFs remains unclear. This study investigates cellulose-based ACFs produced from different precursor materials and fabric structures, tested against the nerve agent simulant, dimethyl methylphosphonate (DMMP) to evaluate their adsorption capabilities. Cotton-based ACFs exhibited considerably higher specific surface area than lyocell-based ACFs, attributed to the higher molecular weight and crystallinity of cotton. Additionally, woven-type ACFs exhibited superior adsorption performance compared to commercial felt-type ACFs due to reduced DMMP migration, which prolonged contact time with adsorption sites. Reducing yarn diameter improved the adsorption performance by lowering the bed void fraction of the adsorption column and facilitating smoother DMMP penetration to the fiber's central region within the yarn. These findings offer valuable insights for applying cellulose-based ACFs in protective clothing against nerve agents. | Kwon, Woong; Jeong, Euigyung | Kyungpook Natl Univ, Dept Text Syst Engn, 80 Daehak Ro, Daegu 41566, South Korea | 57208867074; 35885596300 | wolfpack@knu.ac.kr; | MATERIALS CHEMISTRY AND PHYSICS | MATER CHEM PHYS | 0254-0584 | 1879-3312 | 323 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 4.7 | 32.5 | 0.66 | 2025-05-07 | 2 | 2 | Chemical warfare agent; Dimethyl methylphosphonate; Fabric structure; Yarn diameter; Adsorption property | CHEMICAL WARFARE AGENTS; DIMETHYL METHYLPHOSPHONATE; BREAKTHROUGH CURVES; MOLECULAR-WEIGHT; PORE STRUCTURE; DECOMPOSITION | Adsorption property; Chemical warfare agent; Dimethyl methylphosphonate; Fabric structure; Yarn diameter | Activated Carbon; Adsorption; Carbon Fibers; Cotton; Esters; Pore Size; Activated carbon; Adsorption; Carbon fibers; Cotton; Esters; Hosiery manufacture; Pore size; Protective clothing; Void fraction; Weaving; Wool; Yarn; Activated carbon fibres; Adsorption performance; Adsorption properties; Chemical warfare agents; Dimethyl methylphosphonate; Fabric structures; Materials structure; Nerve agents; Precursor materials; Yarn diameter; Cellulose | English | 2024 | 2024-09-01 | 10.1016/j.matchemphys.2024.129651 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Anterior Choroidal Artery Aneurysm Clipping: Angiographic Diagnostics and Surgical Tactics Focused on Visualizing the Anterior Choroidal Artery Behind the Aneurysm | OBJECTIVE: This study describes our experiences with anterior choroidal artery (AChA) aneurysm clipping with a focus on visualizing the AChA just behind the aneurysm to identify the risk factors for adhesion of the AChA or its branches to the posterior wall of the AChA aneurysm. METHODS: The initial segment of the AChA just behind the aneurysm was evaluated preoperatively using threedimensional (3D) rotational angiography, and its course was designated as posteromedial, posterior, or posterolateral. The posterior aspect of the AChA aneurysm was inspected intraoperatively using an endoscope or micromirror. - RESULTS: Based on 3D rotational angiography, the main trunk of the AChA showed a posteromedial (n = 47, 57.3%), posterior (n = 18, 22.0%), or posterolateral (n = 17, 20.7%) course just behind the aneurysm. Intraoperatively, 14.6% (12 of 82) of the clipped AChA aneurysms revealed an AChA branch adhered to the posterior wall of the aneurysm. A multivariate analysis revealed that the posterior or posterolateral course of the initial segment of the AChA was a statistically significant risk factor for adhesion of an AChA branch to the posterior wall of the aneurysm (odds ratio [OR] 21.083, 95% confidence interval [CI] 2.567- 173.166, P = 0.005). CONCLUSIONS: The initial course of the AChA just behind an AChA aneurysm can be evaluated using 3D rotational angiography. In contrast to a posteromedial course, a posterior or posterolateral course of the AChA just behind an AChA aneurysm can be a significant risk factor for adhesion of an AChA branch to the posterior wall of an AChA aneurysm. | Park, Jaechan; Son, Wonsoo; Kim, Myungsoo; Shin, Im Hee | Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Daegu Catholic Univ, Sch Med, Dept Med Stat, Daegu, South Korea | 44661451000; 36676729400; 57210943611; 16403335700 | jparkmd@hotmail.com; | WORLD NEUROSURGERY | WORLD NEUROSURG | 1878-8750 | 1878-8769 | 187 | SCIE | CLINICAL NEUROLOGY;SURGERY | 2024 | 2.1 | 32.5 | 0.84 | 2025-05-07 | 1 | 1 | Anterior choroidal artery; Clipping; Intracranial aneurysm; Microsurgical technique | SUPERCILIARY KEYHOLE APPROACH; MICROSURGICAL ANATOMY; ISCHEMIC COMPLICATIONS; SURGERY; EXPERIENCE | Anterior choroidal artery; Clipping; Intracranial aneurysm; Microsurgical technique | Adult; Aged; Cerebral Angiography; Female; Humans; Imaging, Three-Dimensional; Intracranial Aneurysm; Male; Middle Aged; Neurosurgical Procedures; Surgical Instruments; adult; aneurysm clipping; angiography; anterior choroidal artery; Article; cell adhesion; controlled study; female; human; intracranial aneurysm; major clinical study; male; microsurgery; middle aged; multivariate analysis; risk factor; aged; brain angiography; diagnostic imaging; intracranial aneurysm; neurosurgery; procedures; surgery; surgical equipment; three-dimensional imaging | English | 2024 | 2024-07 | 10.1016/j.wneu.2024.05.050 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
