| ○ | ○ | Article | Diagnostic Delay and Its Predictors in Cluster Headache | ObjectiveCluster headache (CH) is a rare, primary headache disorder, characterized of excruciating, strictly one-sided pain attacks and ipsilateral cranial autonomic symptoms. Given the debilitating nature of CH, delayed diagnosis can increase the disease burden. Thus, we aimed to investigate the diagnostic delay, its predictors, and clinical influence among patients with CH. MethodsData from a prospective multicenter CH registry over a 4-year period were analyzed. CH was diagnosed according to the International Classification of Headache Disorders (ICHD)-3 criteria, and diagnostic delay of CH was assessed as the time interval between the year of the first onset and the year of CH diagnosis. Patients were classified into three groups according to the tertiles of diagnostic delay (1st tertile, = 7 years). ResultsOverall, 445 patients were evaluated. The mean duration of diagnosis delay was 5.7 +/- 6.7 years, (range, 0-36 years). Regarding the age of onset, majority of young patients (age 40 years) belonged to the third tertile (9.0%). For year of onset, the proportion of patients in the 3rd tertile was the highest for the groups before the publication year of the ICHD-2 (74.7%) and the lowest for the groups after the publication year of the ICHD-3 beta version (0.5%). Compared with the first CH, episodic CH [multivariable-adjusted odds ratio (aOR) = 5.91, 95% CI = 2.42-14.48], chronic CH (aOR = 8.87, 95% CI = 2.66-29.51), and probable CH (aOR = 4.12, 95% CI = 1.48-11.43) were associated with the tertiles of diagnostic delay. Age of onset (aOR = 0.97, 95% CI = 0.95-0.99) and PHQ-9 score (aOR = 0.96, 95% CI = 0.93-0.99) were inversely associated with the tertile of diagnostic delay. The prevalence of suicidal ideation was highest in the patients of the third tertile. The mean HIT-6 score increased significantly with the diagnostic delay (p = 0.041). ConclusionsPatients with a younger onset of CH have a higher risk of diagnostic delay. Nevertheless, the rate of delayed diagnosis gradually improved over time and with the publication of the ICHD criteria, supporting the clinical significance of diagnostic clinical criteria and headache education to reduce the disease burden of CH. | Kim, Byung-Su; Chung, Pil-Wook; Kim, Byung-Kun; Lee, Mi Ji; Chu, Min Kyung; Ahn, Jin-Young; Bae, Dae Woong; Song, Tae-Jin; Sohn, Jong-Hee; Oh, Kyungmi; Kim, Daeyoung; Kim, Jae-Moon; Park, Jeong Wook; Chung, Jae Myun; Moon, Heui-Soo; Cho, Soohyun; Seo, Jong-Geun; Kim, Soo-Kyoung; Choi, Yun-Ju; Park, Kwang-Yeol; Chung, Chin-Sang; Cho, Soo-Jin | Bundang Jesaeng Gen Hosp, Daejin Med Ctr, Dept Neurol, Seongnam, South Korea; Sungkyunkwan Univ, Kangbuk Samsung Hosp, Dept Neurol, Sch Med, Seoul, South Korea; Eulji Univ, Eulji Hosp, Dept Neurol, Seoul, South Korea; Sungkyunkwan Univ, Neurosci Ctr, Samsung Med Ctr, Dept Neurol,Sch Med, Seoul, South Korea; Yonsei Univ, Severance Hosp, Dept Neurol, Coll Med, Seoul, South Korea; Seoul Med Ctr, Dept Neurol, Seoul, South Korea; Catholic Univ Korea, Coll Med, Dept Neurol, Suwon, South Korea; Ewha Womans Univ, Seoul Hosp, Coll Med, Dept Neurol, Seoul, South Korea; Hallym Univ, Chuncheon Sacred Heart Hosp, Dept Neurol, Coll Med, Chunchon, South Korea; Korea Univ, Dept Neurol, Coll Med, Seoul, South Korea; Chungnam Natl Univ, Dept Neurol, Coll Med, Daejeon, South Korea; Catholic Univic Korea, Uijeongbu St Marys Hosp, Dept Neurol, Coll Med, Uijongbu, South Korea; Inje Univ, Dept Neurol, Coll Med, Seoul, South Korea; Eulji Univ, Dept Neurol, Uijongbu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Gyeongsang Natl Univ, Dept Neurol, Coll Med, Jinju, South Korea; Gyeonsang Natl Univ Hosp, Jinju, South Korea; Dr Chois Neurol Clin, Jeonju, South Korea; Chung Ang Univ Hosp, Dept Neurol, Seoul, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Dept Neurol, Coll Med, Hwaseong, South Korea | Cho, Soo JIn/AFA-0831-2022; Kim, Yong-Jae/JQW-5758-2023; Kim, Jung Oh/JDC-5061-2023; Cho, Soo-Jin/AFA-0831-2022; Kim, Seung Woo/HOF-6634-2023 | 56643414800; 17134300300; 55855930800; 56011161600; 24491536700; 56739714100; 57210731443; 55507164200; 55427836400; 16048029600; 57191361218; 34769781900; 25623601500; 50461391000; 34977353600; 57199760392; 16040307500; 57051653200; 35092245700; 36060099300; 7403613322; 35386173500 | dowonc@naver.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 1.14 | 2025-06-25 | 11 | 11 | headache; primary headache disorder; cluster headache; delayed diagnosis; Korea | INTERNATIONAL CLASSIFICATION; CLINICAL-FEATURES; DEPRESSION | cluster headache; delayed diagnosis; headache; Korea; primary headache disorder | adolescent; adult; anxiety disorder; Article; cluster headache; delayed diagnosis; depression; diagnosis time; disease association; disease severity; female; Generalized Anxiety Disorder-7; human; ICHD-3; major clinical study; male; middle aged; odds ratio; onset age; Patient Health Questionnaire 9; prediction; prevalence; probability; publishing; risk assessment; suicidal ideation; suicide attempt; young adult | English | 2022 | 2022-02-10 | 10.3389/fneur.2022.827734 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Differential Involvement of Lateral Semicircular Canal and Otolith Organs in Common Vestibular Disorders | Semicircular canal and otolith functions came to be evaluated recently, but comprehensive and comparative analysis of canal and otolith dysfunction in common vestibular disorders is lacking. We aimed to analyze the abnormal rates of canal and otolith function in common vestibular disorders. We enrolled 302 patients who were managed for 2 months in a dizziness clinic. Results of caloric, video head impulse test (vHIT), and cervical and ocular vestibular evoked myogenic potential (cVEMP and oVEMP) tests were analyzed and compared among various diagnoses. Vestibular disorders diagnosed included recurrent vestibulopathy (RV, 27%), vestibular migraine (VM, 21%), benign paroxysmal positional vertigo (BPPV, 17%), Meniere's disease (MD, 11%), vestibular neuritis (VN, 10%), orthostatic dizziness (7%), and central lesions (3%). Lateral canal dysfunction was found most in VN (100%) and less commonly in definite MD (75%), RV (46%) and definite VM (29%). Abnormal caloric results were more common than abnormal vHIT in all disorders. Otolith dysfunction was found more frequently than lateral canal dysfunction in most vestibular disorders except VN. An abnormal cVEMP was more frequent in definite MD than the other disorders. Isolated otolith dysfunction without lateral canal dysfunction was the most found in BPPV, followed by definite VM, RV, and definite MD in decreasing order. Various patterns of involvement in canal and otoliths were revealed in vestibular disorders, suggesting different pathogenesis. | Kim, Yehree; Kang, Byung Chul; Yoo, Myung Hoon; Park, Hong Ju | Univ Ulsan, Coll Med, Dept Otorhinolaryngol Head & Neck Surg, Asan Med Ctr, Seoul, South Korea; Univ Ulsan, Ulsan Univ Hosp, Dept Otorhinolaryngol Head & Neck Surg, Coll Med, Ulsan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Daegu, South Korea | 57195399872; 7401684593; 22956750000; 57213039619 | dzness@hotmail.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 0.92 | 2025-06-25 | 8 | 8 | dizziness; vertigo; head impulse test; otolith; vestibular-evoked myogenic potential (VEMP); benign paroxysmal positional vertigo (BPPV); Meniere disease; vestibular neuritis (VN) | VIDEO HEAD IMPULSE; PAROXYSMAL POSITIONAL VERTIGO; CORRECTIVE SACCADES; POTENTIALS; DIZZINESS; EPIDEMIOLOGY; DYSFUNCTION; POPULATION; SUPERIOR; DISEASE | benign paroxysmal positional vertigo (BPPV); dizziness; head impulse test; Meniere disease; otolith; vertigo; vestibular neuritis (VN); vestibular-evoked myogenic potential (VEMP) | adult; Article; benign paroxysmal positional vertigo; caloric vestibular test; cohort analysis; comparative study; controlled study; disease association; dizziness; ear disease; female; head impulse test; human; lateral semicircular canal; lateral semicircular canal dysfunction; major clinical study; male; medical record review; Meniere disease; middle aged; orthostatic dizziness; otolith; otolith dysfunction; retrospective study; semicircular canal; vestibular disorder; vestibular evoked myogenic potential; vestibular migraine; vestibular neuronitis | English | 2022 | 2022-01-31 | 10.3389/fneur.2022.819385 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Estimating the incubated river water quality indicator based on machine learning and deep learning paradigms: BOD5 Prediction | As an indicator measured by incubating organic material from water samples in rivers, the most typical characteristic of water quality items is biochemical oxygen demand (BOD5) concentration, which is a stream pollutant with an extreme circumstance of organic loading and controlling aquatic behavior in the eco-environment. Leading monitoring approaches including machine leaning and deep learning have been evolved for a correct, trustworthy, and low-cost prediction of BOD5 concentration. The addressed research investigated the efficiency of three standalone models including machine learning (extreme learning machine (ELM) and support vector regression (SVR)) and deep learning (deep echo state network (Deep ESN)). In addition, the novel double-stage synthesis models (wavelet-extreme learning machine (Wavelet-ELM), wavelet-support vector regression (Wavelet-SVR), and wavelet-deep echo state network (Wavelet-Deep ESN)) were developed by integrating wavelet transformation (WT) with the different standalone models. Five input associations were supplied for evaluating standalone and double-stage synthesis models by determining diverse water quantity and quality items. The proposed models were assessed using the coefficient of determination (R-2), Nash-utcliffe (NS) efficiency, and root mean square error (RMSE). The significance of addressed research can be found from the overall outcomes that the predictive accuracy of double-stage synthesis models were not always superior to that of standalone models. Overall results showed that the SVR with 3th distribution (NS = 0.915) and the Wavelet-SVR with 4th distribution (NS = 0.915) demonstrated more correct outcomes for predicting BOD5 concentration compared to alternative models at Hwangji station, and the Wavelet-SVR with 4th distribution (NS = 0.917) was judged to be the most superior model at Toilchun station. In most cases for predicting BOD5 concentration, the novel double-stage synthesis models can be utilized for efficient and organized data administration and regulation of water pollutants on both stations, South Korea. | Kim, Sungwon; Alizamir, Meysam; Seo, Youngmin; Heddam, Salim; Chung, Il-Moon; Kim, Young-Oh; Kisi, Ozgur; Singh, Vijay P. | Dongyang Univ, Dept Railrd Construct & Safety Engn, Yeongju 36040, South Korea; Islamic Azad Univ, Dept Civil Engn, Hamedan Branch, Hamadan, Hamadan, Iran; Kyungpook Natl Univ, Dept Construct & Environm Engn, Sangju 37224, South Korea; Univ 20 Aout 1955, Fac Sci, Agron Dept, Hydraul Div,Lab Res Biodivers Interact Ecosyst &, BP 26, Skikda, Algeria; Korea Inst Civil Engn & Bldg Technol, Dept Hydro Sci & Engn Res, Goyang Si 10223, South Korea; Seoul Natl Univ, Dept Civil Engn, Seoul, South Korea; Univ Appl Sci, Dept Civil Engn, D-23562 Lubeck, Germany; Texas A&M Univ, Dept Biol & Agr Engn, College Stn, TX 77843 USA; Texas A&M Univ, Zachry Dept Civil Engn, College Stn, TX 77843 USA | HEDDAM, SALIM/B-8647-2015; Malik, Anurag/AAF-5402-2020; Alizamir, Meysam/AAK-6312-2021; Singh, Vijay/AAH-9906-2020; Kisi, Ozgur/AAD-8932-2019 | 36349835400; 57188682009; 55321312700; 25226555100; 7201867993; 56066657300; 6507051085; 57211219633 | swkim1968@dyu.ac.kr; | MATHEMATICAL BIOSCIENCES AND ENGINEERING | MATH BIOSCI ENG | 1547-1063 | 1551-0018 | 19 | 12 | SCIE | MATHEMATICAL & COMPUTATIONAL BIOLOGY | 2022 | 2.6 | 42.7 | 0.78 | 2025-06-25 | 5 | 6 | biochemical oxygen demand; wavelet transformation; deep echo state network; extreme learning machine; support vector regression | WAVELET TRANSFORM; PERFORMANCE; NETWORK | biochemical oxygen demand; deep echo state network; extreme learning machine; support vector regression; wavelet transformation | Deep Learning; Environmental Monitoring; Machine Learning; Neural Networks, Computer; Quality Indicators, Health Care; Rivers; Water Quality; Deep learning; Dissolved oxygen; Efficiency; Forecasting; Knowledge acquisition; Learning systems; Mean square error; Regression analysis; River pollution; Rivers; Water quality; Wavelet transforms; Deep echo state network; Double stage; Echo state networks; Extreme learning machine; Learning machines; Machine-learning; Support vector regressions; Synthesis models; Wavelet support vectors; Wavelet transformations; environmental monitoring; health care quality; machine learning; procedures; river; water quality; Biochemical oxygen demand | English | 2022 | 2022 | 10.3934/mbe.2022595 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Frictional force analysis of stent retriever devices using a realistic vascular model: Pilot study | Objective: To date, no vascular model to analyze frictional forces between stent retriever devices and vessel walls has been designed to be similar to the real human vasculature. We developed a novel in vitro intracranial cerebrovascular model and analyzed frictional forces of three stent retriever devices. Methods: A vascular mold was created based on digital subtraction angiography of a patient's cerebral vessels. The vascular model was constructed using polydimethylsiloxane (PDMS, Dow Corning, Inc.) as a silicone elastomer. The vascular model was coated on its inner surface with a lubricating layer to create a low coefficient of friction (similar to 0.037) to closely approximate the intima. A pulsatile blood pump was used to produce blood flow inside the model to approximate real vascular conditions. The frictional forces of Trevo XP, Solitaire 2, and Eric 4 were analyzed for initial and maximal friction retrieval forces using this vascular model. The total pulling energy generated during the 3 cm movement was also obtained. Results: Results for initial retrieval force were as follows: Trevo, 0.09 +/- 0.04 N; Solitaire, 0.25 +/- 0.07 N; and Eric, 0.33 +/- 0.21 N. Results for maximal retrieval force were as follows: Trevo, 0.36 +/- 0.07 N; Solitaire, 0.54 +/- 0.06 N; and Eric, 0.80 +/- 0.13 N. Total pulling energy (N.cm) was 0.40 +/- 0.10 in Trevo, 0.65 +/- 0.10 in Solitaire, and 0.87 +/- 0.14 in Eric, respectively. Conclusions: Using a realistic vascular model, different stent retriever devices were shown to have statistically different frictional forces. Future studies using a realistic vascular model are warranted to assess SRT devices. | Kwak, Youngseok; Son, Wonsoo; Kim, Byoung-Joon; Kim, Myungsoo; Yoon, Sang-Youl; Park, Jaechan; Lim, Jongkyeong; Kim, Joonwon; Kang, Dong-Hun | Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Gachon Univ, Dept Mech Engn, Seongnam Si, South Korea; Pohang Univ Sci & Technol POSTECH, Dept Mech Engn, Pohang, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea | 57204667265; 36676729400; 57201448189; 57210943611; 57195615457; 44661451000; 57201128962; 56962756200; 8977805800 | joonwon@postech.ac.kr;kdhdock@hotmail.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 0.69 | 2025-06-25 | 4 | 6 | acute ischemic stroke; vascular model; frictional retrieval force; Trevo XP; Solitaire 2; Eric 4 | ACUTE ISCHEMIC-STROKE; INTRAVENOUS T-PA; MECHANICAL THROMBECTOMY; ENDOVASCULAR TREATMENT; RANDOMIZED-TRIAL; THERAPY; VS. | acute ischemic stroke; Eric 4; frictional retrieval force; Solitaire 2; Trevo XP; vascular model | dimeticone; acute ischemic stroke; Article; blood flow; coating (procedure); controlled study; digital subtraction angiography; equipment design; friction; in vitro study; pilot study; process design; quantitative analysis; vascular resistance | English | 2022 | 2022-08-24 | 10.3389/fneur.2022.964354 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Movement Disorders Associated With Cerebral Artery Stenosis: A Nationwide Study | BackgroundStudies of secondary movement disorder (MD) caused by cerebrovascular diseases have primarily focused on post-stroke MD. However, MD can also result from cerebral artery stenosis (CAS) without clinical manifestations of stroke. In this study, we aimed to investigate the clinical characteristics of MD associated with CAS. Materials and MethodsA nationwide multicenter retrospective analysis was performed based on the data from patients with CAS-associated MDs from 16 MD specialized clinics in South Korea, available between January 1999 and September 2019. CAS was defined as the >50% luminal stenosis of the major cerebral arteries. The association between MD and CAS was determined by MD specialists using pre-defined clinical criteria. The collected clinical information included baseline demographics, features of MD, characteristics of CAS, treatment, and MD outcomes. Statistical analyses were performed to identify factors associated with the MD outcomes. ResultsThe data from a total of 81 patients with CAS-associated MD were analyzed. The mean age of MD onset was 60.5 +/- 19.7 years. Chorea was the most common MD (57%), followed by tremor/limb-shaking, myoclonus, and dystonia. Atherosclerosis was the most common etiology of CAS (78%), with the remaining cases attributed to moyamoya disease (MMD). Relative to patients with atherosclerosis, those with MMD developed MD at a younger age (p < 0.001) and had a more chronic mode of onset (p = 0.001) and less acute ischemic lesion (p = 0.021). Eight patients who underwent surgical treatment for CAS showed positive outcomes. Patients with acute MD onset had a better outcome than those with subacute-to-chronic MD onset (p = 0.008). ConclusionsThis study highlights the spectrum of CAS-associated with MD across the country. A progressive, age-dependent functional neuronal modulation in the basal ganglia due to CAS may underlie this condition. | Park, Kye Won; Choi, Nari; Oh, Eungseok; Lyoo, Chul Hyoung; Baek, Min Seok; Kim, Han-Joon; Yoo, Dalla; Lee, Jee-Young; Choi, Ji-Hyun; Lee, Jae Hyeok; Koh, Seong-Beom; Sung, Young Hee; Cho, Jin Whan; Yang, Hui-Jun; Park, Jinse; Shin, Hae-Won; Ahn, Tae-Beom; Ryu, Ho-Sung; You, Sooyeoun; Choi, Seong-Min; Kim, Bum Joon; Lee, Seung Hyun; Chung, Sun Ju | Eulji Univ Sch Med, Uijeongbu Eulji Med Ctr, Dept Neurol, Uijongbu, South Korea; Heavenly Hosp, Dept Neurol, Goyang, South Korea; Chungnam Natl Univ Coll Med, Chungnam Natl Univ Hosp, Dept Neurol, Daejeon, South Korea; Yonsei Univ Coll Med, Gangnam Severance Hosp, Dept Neurol, Seoul, South Korea; Yonsei Univ Wonju Coll Med, Wonju Severance Christian Hosp, Dept Neurol, Wonju, South Korea; Seoul Natl Univ Hosp, Coll Med, Movement Disorder Ctr, Dept Neurol, Seoul, South Korea; Kyung Hee Univ Coll Med, Dept Neurol, Seoul, South Korea; Seoul Natl Univ, Seoul Natl Univ Med Coll, Seoul Metropolitan Govt Boramae Med Ctr, Dept Neurol, Seoul, South Korea; Pusan Natl Univ Yangsan Hosp, Pusan Natl Univ Sch Med, Dept Neurol, Yangsan, South Korea; Korea Univ Coll Med, Guro Hosp, Dept Neurol, Seoul, South Korea; Gachon Univ Gil Med Ctr, Dept Neurol, Incheon, South Korea; Sungkyunkwan Univ Sch Med, Samsung Med Ctr, Dept Neurol, Seoul, South Korea; Ulsan Univ Hosp, Univ Ulsan Coll Med, Dept Neurol, Ulsan, South Korea; Inje Univ, Haeundae Paik Hosp, Dept Neurol, Busan, South Korea; Chung Ang Univ Coll Med, Dept Neurol, Seoul, South Korea; Kyungpook Natl Univ Hosp, Dept Neurol, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Neurol, Daegu, South Korea; Chonnam Natl Univ Hosp, Dept Neurol, Gwangju, South Korea; Univ Ulsan Coll Med, Asan Med Ctr, Dept Neurol, Seoul, South Korea | YANG, June/AHC-4229-2022; Ahn, Tae-Beom/AAG-1309-2021; Oh, Eungseok/AAL-8935-2020; Lee, Jae-Hyeok/ISV-2976-2023; Kim, Jinkwon/AAR-6729-2021; Kim, Jin-Wook/J-5442-2012 | 57194448346; 57208574478; 55833749700; 6505826405; 57195970428; 36067006300; 57202011449; 36062860800; 57199099845; 57226781339; 8573789300; 35278917000; 35084917900; 40662011700; 54938807200; 35314117600; 24340610100; 57014206500; 55355547900; 7408121966; 57214661365; 57219164267; 56882955600 | sjchung@amc.seoul.kr; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 0 | 2025-06-25 | 0 | 0 | movement disorders; intracranial artery stenosis; extracranial artery stenosis; moyamoya disease; cerebral artery stenosis | PEDIATRIC MOYAMOYA-DISEASE; LIMB-SHAKING TIA; ACUTE HEMICHOREA; DYSTONIA | cerebral artery stenosis; extracranial artery stenosis; intracranial artery stenosis; movement disorders; moyamoya disease | adult; aged; angiography; anterior cerebral artery; Article; atherosclerosis; brain artery; cerebrovascular accident; chorea; clinical feature; clinical outcome; coronary artery disease; demographics; diabetes mellitus; dystonia; female; follow up; human; hyperlipidemia; hypertension; internal carotid artery; limb tremor; major clinical study; male; middle aged; middle cerebral artery; motor dysfunction; moyamoya disease; multicenter study; myoclonus; occlusive cerebrovascular disease; outcome assessment; parkinsonism; posterior cerebral artery; retrospective study; risk factor; smoking; stenosis; tremor; young adult | English | 2022 | 2022-07-14 | 10.3389/fneur.2022.939823 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Predictors and Outcomes of Salvaging the Corticospinal Tract After Thrombectomy in Basilar Artery Occlusion Stroke | BackgroundRegional eloquence of brainstem structures may contribute to neurological status in basilar artery occlusion (BAO) stroke. The corticospinal tract (CST) which is vulnerable to BAO is important for motor activity. This study investigated the impact of CST salvage on outcomes and its associated factors in patients with BAO treated with thrombectomy. MethodsWe retrospectively investigated 88 patients with BAO admitted <= 24 h after onset and presented with motor deficits and who underwent thrombectomy. Patients with a pre-stroke modified Rankin Scale (mRS) score of 4-5 who did not undergo baseline brain computed tomography angiography were excluded. CST salvage was evaluated using follow-up imaging (magnetic resonance imaging [MRI] or computed tomography when MRI was not available) after thrombectomy. A good outcome was defined as a 3-month mRS score of <= 2 or 3 if a patient's pre-stroke mRS score was 3. The associations between CST salvage and outcomes and clinical parameters were analyzed using logistic regression analyses. ResultsThirty-nine (44.3%) patients had CST salvage and the same number of patients had good outcomes. CST salvage was independently associated with a good outcome [adjusted odds ratio (aOR): 18.52, 95% confidence interval (CI): 4.31-79.67, p < 0.001]. After adjusting for confounders, atrial fibrillation (aOR: 3.92, 95% CI: 1.18-13.00, p = 0.026), location of occlusion (mid-BAO; aOR: 0.21, 95% CI: 0.06-0.72, p = 0.013), length of occlusion (involved segment of BAO <2; aOR: 4.77, 95% CI: 1.30-17.59, p = 0.019), and onset-to-puncture-time <= 180 min (aOR: 4.84, 95% CI: 1.13-20.75, p = 0.034) were significantly associated with CST salvage. ConclusionCST salvage was associated with good functional outcomes in patients with BAO treated with thrombectomy. The presence of atrial fibrillation, location and length of BAO may predict CST salvage after thrombectomy, and rapid treatment with thrombectomy may protect this eloquent tract in these patients. | Gwak, Dong-Seok; Choi, WooChan; Kim, Yong-Won; Kang, Dong-Hun; Son, Wonsoo; Hwang, Yang-Ha | Dongguk Univ Ilsan Hosp, Dept Neurol, Goyang, South Korea; Kyungpook Natl Univ Hosp, Dept Neurol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea | HWANG, Yang-Ha/F-3068-2013 | 57205148053; 57225111001; 56203298200; 8977805800; 36676729400; 7402311308 | yangha.hwang@gmail.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 0.23 | 2025-06-25 | 2 | 2 | pyramidal tracts; thrombectomy; basilar artery; stroke; ischemic stroke | ACUTE ISCHEMIC-STROKE; ENDOVASCULAR TREATMENT; LESION | basilar artery; ischemic stroke; pyramidal tracts; stroke; thrombectomy | aged; artery occlusion; Article; atrial fibrillation; basilar artery occlusion stroke; cardioembolic stroke; cerebrovascular accident; clinical effectiveness; computed tomographic angiography; female; functional assessment; human; logistic regression analysis; major clinical study; male; motor dysfunction; multivariate logistic regression analysis; nuclear magnetic resonance imaging; outcome assessment; pyramidal tract; Rankin scale; recanalization; retrospective study; scoring system; thrombectomy; treatment outcome; very elderly | English | 2022 | 2022-05-10 | 10.3389/fneur.2022.878638 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Self-reported Non-celiac Gluten Sensitivity in the Korean Population: Demographic and Clinical Characteristics | Background/Aims Non-celiac gluten sensitivity is characterized by intestinal and extra intestinal symptoms associated with the consumption of gluten containing food. Since biomarkers for non-celiac gluten sensitivity are lacking, its prevalence is estimated based on self-reported symptoms. However, no data exist on self-reported non-celiac gluten sensitivity in the Korean population. Thus, we aim to investigate the prevalence of self-reported non-celiac gluten sensitivity in the Korean population and to determine its demographic and clinical characteristics. Methods This study surveyed Korean participants aged 18-80 years who visited gastroenterology outpatient clinics at 9 tertiary hospitals in South Korea from January 2016 to February 2017. They were questioned regarding symptoms related to gluten ingestion: degree of discomfort (visual analog scale score), frequency, time of symptom onset, and duration. Abdominal discomfort caused by 11 different kinds of gluten-containing Korean food items was investigated. Results More non-celiac gluten sensitivity self-reporters were identified among those with irritable bowel syndrome (33.6%) than among controls (5.8%). Major gastrointestinal symptoms included bloating (75.0%), abdominal discomfort (71.3%), and belching (45.0%). Common extra-intestinal symptoms included fatigue (20.0%) and headache (13.7%). More than half of those who self-reported non celiac gluten sensitivity (66.3%) developed symptoms within 1 hour of food ingestion, and symptoms were localized in the upper abdomen (37.5%) and entire abdomen (30.0%). Conclusion Our findings suggest that if there are gluten-related symptoms in irritable bowel syndrome, the possibility of accompanying non-celiac gluten sensitivity should be considered.

| ○ | ○ | Article | Serum vitamin E level and functional prognosis after traumatic brain injury with intracranial injury: A multicenter prospective study | BackgroundTraumatic brain injury (TBI) is a major public health problem with high mortality and disability. Vitamin E, one of the antioxidants for treatment of TBI, has not been sufficiently evaluated for predicting prognosis of TBI. This study aimed to evaluate the prognostic value of vitamin E on functional outcomes of TBI patients with intracranial injury. MethodsA multi-center prospective cohort study was conducted in five university hospitals between 2018 and 2020. Adult TBI patients who visited the emergency department (ED) with intracranial hemorrhage or diffuse axonal injury confirmed by radiological examination were eligible. Serum vitamin E levels (mg/dL) were categorized into 4 groups: low (0.0-5.4), low-normal (5.5-10.9), high-normal (11.0-16.9), and high (17.0-). Study outcomes were set as 1- and 6-month disability (Glasgow outcome scale (GOS) 1-4). Multilevel logistic regression analysis was conducted to calculate the adjusted odds ratios (AORs) of vitamin E for related outcomes. ResultsAmong 550 eligible TBI patients with intracranial injury, the median (IQR) of serum vitamin E was 10.0 (8.0-12.3) mg/dL; 204/550 (37.1%) had 1-month disability and 197/544 (36.1%) had 6-month disability of GOS 1-4. Compared with the high-normal group, the odds of 1-month disability and 6-month disability increased in the low and low-normal group (AORs (95% CIs): 3.66 (1.62-8.27) and 2.60 (1.15-5.85) for the low group and 1.63 (1.08-2.48) and 1.60 (1.04-2.43) for the low-normal group, respectively). ConclusionLow serum vitamin E level was associated with poor prognosis at 1 and 6 months after TBI with intracranial injury. | Park, Gwan Jin; Ro, Young Sun; Yoon, Hanna; Lee, Stephen Gyung Won; Jung, Eujene; Moon, Sung Bae; Kim, Sang Chul; Shin, Sang Do | Chungbuk Natl Univ Hosp, Dept Emergency Med, Cheongju, South Korea; Seoul Natl Univ Hosp, Biomed Res Inst, Lab Emergency Med Serv, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Emergency Med, Seoul, South Korea; Seoul Natl Univ, Dept Emergency Med, Coll Med, Seoul, South Korea; Seoul Natl Univ, Boramae Med Ctr, Dept Emergency Med, Seoul, South Korea; Chonnam Natl Univ Hosp, Dept Emergency Med, Gwangju, South Korea; Kyungpook Natl Univ, Sch Med, Dept Emergency Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Daegu, South Korea | Do Shin, Sang/D-6020-2012 | 57193389046; 37665990400; 57218530108; 57221045307; 57194543281; 57191584601; 7601581324; 57049712400 | Ro.youngsun@gmail.com; | FRONTIERS IN NEUROLOGY | FRONT NEUROL | 1664-2295 | 13 | SCIE | CLINICAL NEUROLOGY;NEUROSCIENCES | 2022 | 3.4 | 42.7 | 0.34 | 2025-06-25 | 3 | 3 | vitamin E; prognosis; biomarker; traumatic brain injury; trauma | ALPHA-TOCOPHEROL; ANTIOXIDANT THERAPY; OXIDATIVE DAMAGE; HEAD-INJURY; OUTCOMES; IMPACT; MILD | biomarker; prognosis; trauma; traumatic brain injury; vitamin E | alpha tocopherol; biological marker; adult; aged; Article; axonal injury; brain injury; chronic kidney failure; chronic liver failure; clinical trial; cohort analysis; computer assisted tomography; controlled study; diabetes mellitus; diagnostic test accuracy study; disability; female; Glasgow outcome scale; high performance liquid chromatography; hospital discharge; human; hypertension; major clinical study; multicenter study; nuclear magnetic resonance imaging; obesity; outcome assessment; prognosis; prospective study; receiver operating characteristic; subarachnoid hemorrhage; subdural hematoma; traumatic brain injury; very elderly | English | 2022 | 2022-10-19 | 10.3389/fneur.2022.1008717 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Annona reticulata leaves-assisted synthesis of zinc oxide nanoparticles and assessment of cytotoxicity and photocatalytic impact | The objective of this study is to examine the novel usage of the aqueous leaf extract of Annona reticulata (AR) to produce zinc oxide nanoparticles (AR-ZnONPs) by reducing zinc nitrate. Fourier-transform infrared (FT-IR) spectroscopy analysis revealed that phytochemical compounds in AR leaf extract was responsible for capping and effective stabilization of AR-ZnONPs. The energy-dispersive X-ray (EDX) spectra showed the existence of a zinc peak at 1 keV. In addition, the arrangement of a face-centered cubic crystalline construction was also confirmed by X-ray diffraction (XRD) analysis. The biologically produced AR-ZnONPs have a potential cytotoxicity effect against human lung cancer (A549) cells. Furthermore, AR-ZnONPs exhibited tremendously degradation efficiency for the methylene blue (MB) almost 93.45% removal in 70 min sunlight irradiation. | Selvam, K.; Allam, Ahmed A.; Ajarem, Jamaan S.; Sudhakar, C.; Selvankumar, T.; Senthilkumar, B.; Kim, Woong | Mahendra Arts & Sci Coll Autonomous, PG & Res Dept Biotechnol, Namakkal 637501, Tamil Nadu, India; Beni Suef Univ, Fac Sci, Zool Dept, Bani Suwayf, Egypt; King Saud Univ, Coll Sci, Zool Dept, Riyadh, Saudi Arabia; Dept Med & Mol Microbiol, Microtech Labs, Salem 636102, Tamil Nadu, India; Haramaya Univ, Coll Hlth & Med Sci, Dept Med Microbiol, POB 235, Harar, Ethiopia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea | Sudhakar, Chinnappan/Y-8277-2019; ajarem, jaman/AAX-5058-2021; Allam, Ahmed/AAE-6047-2022; Balakrishnan, Senthilkumar/A-8552-2016; Selvam, Kandasamy/AAN-5860-2020; Balakrishnan, Senthilkumar/J-6908-2014 | 57197362853; 35733203400; 6603095964; 56480308500; 24485017700; 56640778400; 55581636400 | ksk.selvam@gmail.com;elshine@knu.ac.kr; | MATERIALS LETTERS | MATER LETT | 0167-577X | 1873-4979 | 309 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 3 | 42.8 | 0.83 | 2025-06-25 | 7 | 10 | Biomimetic synthesis; Zinc oxide nanoparticles; Annona reticulata; Photocatalytic activity; Cytotoxicity effect | METHYLENE-BLUE; DEGRADATION | Annona reticulata; Biomimetic synthesis; Cytotoxicity effect; Photocatalytic activity; Zinc oxide nanoparticles | Aromatic compounds; Biomimetic processes; Cytotoxicity; Degradation; Fourier transform infrared spectroscopy; II-VI semiconductors; Synthesis (chemical); X ray diffraction analysis; ZnO nanoparticles; Annona reticulata; Aqueous leaf extracts; Biomimetic synthesis; Cytotoxicity effects; Energy-dispersive X-rays; Leaf extracts; Photo-catalytic; Phytochemical; X ray spectrum; Zinc oxide nanoparticles; Photocatalytic activity | English | 2022 | 2022-02-15 | 10.1016/j.matlet.2021.131379 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Antibacterial activity of silver nanoparticles phytosynthesized from Glochidion candolleanum leaves | In the present study, Glochidion candolleanum (Wight & Arn.) Chakrab. & M. Gangop. leaf (GCL)-ethyl acetate extract was used for the phytosynthesis of silver nanoparticles (AgNPs) and subjected to antibacterial assay with G(+ve) and G(-ve) bacteria. The GCL center dot AgNPs synthesized were characterized through various spectroscopic and microscopic analyses, while the phytochemical compounds was analyzed by GC-MS. The discrete GCL center dot AgNPs formed were micron-scale range. TEM images of AgNPs reveal that nanoparticles were spherical and ellipsoidal in shape, dispersed uniformly and capped with secondary material of approximate to 10 nm thickness. A maximum inhibition zone of 12.2 mm diameter was observed against Salmonella enterica followed by 11.8 mm diameter against Pseudomonas aeruginosa. GC-MS analysis revealed the occurrence of bioactive phytocompounds in GCL extract, hexamethylcyclotrisiloxane, 2,4,6-cycloheptatrien, benzenepropanoic acid, 2-ethylacridine, benzo[h]quinoline, methyltris(trimethylsiloxy)silane and 5-methyl-2-phenylindolizine. The findings suggest that GCL could be used for developing antibacterial AgNPs against pathogenic bacteria. | Balachandar, Ramalingam; Navaneethan, Rajendran; Biruntha, Muniyandi; Kumar, Krishna Kumar Ashok; Govarthanan, Muthusamy; Karmegam, Natchimuthu | Vinayaka Missions Res Fdn Deemed Univ, Aarupadai Veedu Inst Technol, Dept Biotechnol, Chennai 603104, Tamil Nadu, India; Alagappa Univ, Dept Anim Hlth & Management, Karaikkudi 630003, Tamil Nadu, India; Vels Inst Sci Technol & Adv Studies, Sch Life Sci, Dept Biotechnol, Chennai 600117, Tamil Nadu, India; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Govt Arts Coll Autonomous, Dept Bot, Salem 636007, Tamil Nadu, India | ; Karmegam, Natchimuthu/J-4745-2019; Muniyandi, BIRUNTHA/G-2438-2019; Natchimuthu, Karmegam/J-4745-2019; Kumar, Ashok/AAA-4798-2022; Muthusamy, Govarthanan/C-1491-2014; Balachandar, Ram/U-4629-2018; Govarthanan, Muthusamy/C-1491-2014 | 14018997400; 57222403669; 57203752025; 57184060400; 54881927600; 6506043230 | gova.muthu@gmail.com;kanishkarmegam@gmail.com; | MATERIALS LETTERS | MATER LETT | 0167-577X | 1873-4979 | 311 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 3 | 42.8 | 5.39 | 2025-06-25 | 59 | 65 | Antimicrobial activity; Green synthesis; Glochidion candolleanum; Nanoparticles; Phytochemicals | Antimicrobial activity; Glochidion candolleanum; Green synthesis; Nanoparticles; Phytochemicals | Salmonella; Silver nanoparticles; Synthesis (chemical); Anti-bacterial activity; Anti-microbial activity; Antibacterials; Ethyl-acetate; Glochidion candolleanum; Green synthesis; Micron scale; Microscopic analysis; Phytochemical; Synthesised; Metal nanoparticles | English | 2022 | 2022-03-15 | 10.1016/j.matlet.2021.131572 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Nanoflower shaped NiO/CeO2 p-n junction material for the degradation of pollutant under visible light | The potential need of p-n junctions create an optimistic way of supporting photogenerated electron-hole pair separation and improving interfacial charge-transfer rates. In this context, a p-type semiconductor NiO can couple with n-type CeO2, thus approving visible light activity by forming p-n junctions. The visible light activity of two large band gap semiconductors still lacks some significant reasons. To solve this, for the first time, this paper reports 3D flower shaped p n heterojunction NiO/CeO2 synthesized via thermal decomposition method and studied their properties through various instrumental techniques. Besides, the photocatalytic mechanism of p n junction and the degrading efficiency of organic pollutant methyl orange (MO) for the synthesized catalysts was discussed. This achieves the outstanding activity and showed better stability which are useful for future applications. | Gnanasekaran, Lalitha; Jalil, A.

Synthesized LbLE-AgNPs were found to be hexagonal shape, crystalline nature with a size range of 40-98 nm, and have zeta potential at -0.138 mV, according to the analytical data. The functional groups bonded with LbLE-Ag-NPs were screened as C-Br, C-Cl, OH, C-O-C, and C = C, etc. LbLE-AgNPs exhibited an effective dose-dependent anti-cancerous activity on MDA-MB-231 (breast cancer cell line) and the minimum inhibitory concentration (IC50) value is measured as 95 +/- 0.21 mu g/ml. The induction of apoptosis was also confirmed by fluorescence-based staining upon treatment. The resultant LbLE-Ag-NPs could be used in the anticancer progress as an alternate agent after the detailed scrutinize. | Chitra, K.; Sureshkumar, M.; Vijayakumar, N.; Ajarem, Jamaan S.; Allam, Ahmed A.; Kim, Woong; Kumar, P. | Muthayammal Coll Arts & Sci, Dept Biotechnol, Rasipuram 637408, Tamil Nadu, India; Annamalai Univ, Fac Sci, Dept Biochem & Biotechnol, Annamalainagar 608002, Tamil Nadu, India; King Saud Univ, Coll Sci, Dept Zool, Riyadh, Saudi Arabia; Beni Suef Univ, Fac Sci, Dept Zool, Bani Suwayf, Egypt; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Alagappa Univ, Dept Anim Hlth & Management, Sci Campus, Karaikkudi 630003, Tamil Nadu, India | NATESAN, VIJAYAKUMAR/U-5635-2019; ajarem, jaman/AAX-5058-2021; Ponnuchamy, Kumar/D-3470-2013; Allam, Ahmed/AAE-6047-2022 | 57521904700; 35957520700; 57189345989; 6603095964; 35733203400; 55581636400; 55173720800 | chlorosuresh@gmail.com; | MATERIALS LETTERS | MATER LETT | 0167-577X | 1873-4979 | 312 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2022 | 3 | 42.8 | 0.5 | 2025-06-25 | 5 | 6 | Leucas biflora; Silver Nanoparticles; Anticancer; Phyto-fabrication | Anticancer; Leucas biflora; Phyto-fabrication; Silver Nanoparticles | Cell culture; Cell death; Diseases; Fabrication; Silver compounds; Silver nanoparticles; Synthesis (chemical); Anticancer; Breast Cancer; Green chemistry approaches; Leaf extracts; Leuca biflorum; MDA-MB-231; Phyto fabrications; Potential anticancer agents; Silver nanoparticle; Simple++; Metal nanoparticles | English | 2022 | 2022-04-01 | 10.1016/j.matlet.2022.131706 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
