    Abstract: One of the main characteristics of social anxiety disorder is excessive fear of social evaluation. In such situations, anxiety can influence gaze behaviour. Thus, the current study adopted virtual reality to examine eye gaze pattern of social anxiety disorder patients while presenting different types of speeches. Methods: A total of 79 social anxiety disorder patients and 51 healthy controls presented prepared speeches on general topics and impromptu speeches on self-related topics to a virtual audience while their eye gaze was recorded. Their presentation performance was also evaluated. Results: Overall, social anxiety disorder patients showed less eye gaze towards the audience than healthy controls. Types of speech did not influence social anxiety disorder patients’ gaze allocation towards the audience. However, patients with social anxiety disorder showed significant correlations between the amount of eye gaze towards the audience while presenting self-related speeches and social anxiety cognitions. Conclusion: The current study confirms that eye gaze behaviour of social anxiety disorder patients is aversive and that their anxiety symptoms are more dependent on the nature of topic.

    Abstract: Differential diagnosis of hepatocellular carcinoma and intrahepatic cholangiocarcinoma is sometimes difficult to accurately perform. Methods Eight markers including cytokeratin 7 (CK7), cytokeratin 19 (CK19), MOC31, CD10, glypican 3 (GPC3), claudin 4, biglycan and high mobility group A1 (HMGA1) were immunohistochemically stained in samples from 179 surgically resected hepatocellular carcinomas and 127 intrahepatic cholangiocarcinomas, and the rates of marker expression were statistically compared. Results With the exception of biglycan, 7 of the 8 markers were found to have significantly different expression patterns when comparing the two types of cancer (P 〈 0.05). In intrahepatic cholangiocarcinomas, the expression rates of CK7, CK19, MOC31, claudin 4 and HMGA1 were 83.4%, 89.0%, 88.2%, 69.2%, and 31.5%, respectively. These rates of expression in intrahepatic cholangiocarcinomas were all higher than in those in hepatocellular carcinomas (CK7, 31.3%; CK19, 10.1%; MOC31, 34.0%; claudin 4, 11.2%; and HMGA1, 19.5%). The expression rates of GPC3, CD10, and biglycan were 72.6%, 39.7% and 10.0%, respectively, in hepatocellular carcinoma. These were higher than the rates found in intrahepatic cholangiocarcinomas (GPC3, 7.0%; CD10, 18.1%; and biglycan, 7.0%). In a multivariate logistic regression analysis, GPC3, CK19, MOC31 and claudin 4 were found to be independent markers for differentially diagnosing intrahepatic cholangiocarcinoma. Conclusions Based on our results, GPC3 and CK19 can be used as first-line markers for differential diagnoses of hepatocellular carcinoma and intrahepatic cholangiocarcinoma (accuracy rate, 73.5%), and additional combined screening for claudin 4 and MOC31 markers in GPC3(-) and CK19(-) tumors might increase the accuracy rate for distinguishing hepatocellular carcinoma from intrahepatic cholangiocarcinoma to 88.5%.

    Abstract: We aimed to compare seroprevalence of anti-myelin oligodendrocyte glycoprotein (MOG) and anti-aquaporin-4 (AQP4) antibodies in Korean adults with inflammatory demyelinating diseases (IDDs) of the central nervous system (CNS), based on a multicenter nationwide database. Sera were analyzed using a live cell–based assay for MOG and AQP4 antibodies. Of 586 Korean adults with IDDs of the CNS, 36 (6.1%) and 185 (31.6%) tested positive for MOG and AQP4 antibodies, respectively. No participant showed double positivity. Seroprevalence of MOG antibodies was about five times lower than that of AQP4 antibodies in a large cohort of Korean adults with IDDs of the CNS.

    Abstract: To identify markers of disease and steroid responsiveness in paediatric idiopathic nephrotic syndrome. Methods Whole-transcriptome sequencing was performed of peripheral blood mononuclear cells (PBMCs) from patients with NS. Differentially expressed genes (DEGs) were identified in patients with active NS vs those in remission, and those with steroid-sensitive NS (SSNS) vs steroid-resistant NS (SRNS). Results A total of 1065 DEGs were identified in patients with NS ( n = 10) vs those in remission ( n = 9). These DEGs correlated with cytokine and/or immune system signalling and the extracellular matrix. Comparisons between SSNS ( n = 6) and SRNS ( n = 4) identified 1890 DEGs. These markers of steroid responsiveness were enriched with genes related to the cell cycle, targets of microRNAs, and genes related to cytokines. Conclusions Meaningful DEGs were identified. Additional studies with larger numbers of patients will provide more comprehensive data.

    In: International Journal of Stroke, SAGE Publications, Vol. 18, No. 7 ( 2023-08), p. 812-820
    Abstract: Optimal antithrombotic regimens to prevent recurrent stroke in patients with ischemic stroke due to atrial fibrillation (AF) and atherosclerotic large-vessel stenosis remain unknown. Aims: This study aimed to evaluate the effect of multiple antithrombotic therapies on outcomes at 1 year after ischemic stroke due to two or more causes. Methods: We identified 862 patients with ischemic stroke due to AF and large artery atherosclerosis from the linked data. These patients were categorized into three groups according to antithrombotic therapies at discharge: (1) antiplatelets, (2) oral anticoagulants (OAC), and (3) antiplatelets plus OAC. The study outcomes were recurrent ischemic stroke, composite outcomes for cardiovascular events, and major bleeding after 1 year. Inverse probability of treatment weighting (IPTW) was used to balance the three groups using propensity scores. Results: Among 862 patients, 169 (19.6%) were treated with antiplatelets, 405 (47.0%) were treated with OAC, and 288 (33.4%) were treated with antiplatelets and OAC. After applying IPTW, only OAC had a significant beneficial effect on the 1-year composite outcome (hazard ratio (HR): 0.37, 95% confidence interval (CI): 0.23–0.60, p  〈  0.001) and death (HR: 0.35, 95% CI: (0.19–0.63), p  〈  0.001). The combination of antiplatelet agents and OAC group had an increased risk of major bleeding complications (HR: 5.27, 95% CI: (1.31–21.16), p = 0.019). However, there was no significant difference in 1-year recurrent stroke events among the three groups. Conclusion: This study demonstrated that OAC monotherapy was associated with lower risks of composite outcome and death in patients at 1 year after ischemic stroke due to AF and atherosclerotic stenosis. In addition, the combination of an antiplatelet and OAC had a high risk of major bleeding.

    Abstract: Niemann Pick disease type C1 (NPC) is an autosomal recessive disease characterized by progressive neurological deterioration leading to premature death. In this study, we hypothesized that human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) have the multifunctional abilities to ameliorate NPC symptoms in the brain. To test this hypothesis, hUCB-MSCs were transplanted into the hippocampus of NPC mice in the early asymptomatic stage. This transplantation resulted in the recovery of motor function in the Rota Rod test and impaired cholesterol homeostasis leading to increased levels of cholesterol efflux-related genes such as LXRα, ABCA1, and ABCG5 while decreased levels of 3-hydroxy-3-methylglutaryl coenzyme A reductase were observed in NPC mice. In the cerebrum, hUCB-MSCs enhanced neuronal cell survival and proliferation, where they directly differentiated into electrically active MAP2-positive neurons as demonstrated by whole-cell patch clamping. In addition, we observed that hUCB-MSCs reduced Purkinje neuronal loss by suppression of inflammatory and apoptotic signaling in the cerebellum as shown by immunohistochemistry. We further investigated how hUCB-MSCs enhance cellular survival and inhibit apoptosis in NPC mice. Neuronal cell survival was associated with increased PI3K/AKT and JAK2/STAT3 signaling; moreover, hUCB-MSCs modulated the levels of GABA/glutamate transporters such as GAT1, EAAT2, EAAT3, and GAD6 in NPC mice as assessed by Western blot analysis. Taken together, our findings suggest that hUCB-MSCs might play multifunctional roles in neuronal cell survival and ameliorating motor deficits of NPC mice.

    Abstract: The optimal duration of dual antiplatelet therapy (DAPT) with clopidogrel-aspirin for the large artery atherosclerotic (LAA) stroke subtype has been debated. Aims: To determine whether the 1-year risk of recurrent vascular events could be reduced by a longer duration of DAPT in patients with the LAA stroke subtype. Methods and study design: A total of 4806 participants will be recruited to detect a statistically significant relative risk reduction of 22% with 80% power and a two-sided alpha error of 0.05, including a 10% loss to follow-up. This is a registry-based, multicenter, prospective, randomized, open-label, blinded end point study designed to evaluate the efficacy and safety of a 12-month duration of DAPT compared with a 3-month duration of DAPT in the LAA stroke subtype. Patients will be randomized (1:1) to either DAPT for 12 months or DAPT for 3 months, followed by monotherapy (either aspirin or clopidogrel) for the remaining 9 months. Study outcomes: The primary efficacy outcome of the study is a composite of stroke (ischemic or hemorrhagic), myocardial infarction, and all-cause mortality for 1 year after the index stroke. The secondary efficacy outcomes are (1) stroke, (2) ischemic stroke or transient ischemic attack, (3) hemorrhagic stroke, and (4) all-cause mortality. The primary safety outcome is major bleeding. Discussion: This study will help stroke physicians determine the appropriate duration of dual therapy with clopidogrel-aspirin for patients with the LAA stroke subtype.

    Abstract: Drug resistance is a major limitation to the long-term efficacy of controlling chronic hepatitis B (CHB). There is a growing need to analyse multiple mutations associated with drug resistance because sequential or combinational use of antivirals is increasingly being used in treatment. In this study, we introduced a multiplex restriction fragment mass polymorphism (RFMP) assay for detecting mutations conferring entecavir and lamivudine resistance, and compared its performance with direct or clonal sequencing assays. Methods Multiplex PCR was performed with mixed primers designed to interrogate rt184, rt202, rt204 and rt250. The PCR products were digested with restriction enzymes and the resulting fragments were analysed by mass spectrometry. A total of 251 serum samples, taken serially from 45 patients who received entecavir treatment after confirmed diagnosis of lamivudine resistance and inadequate adefovir dipivoxil response, were analysed by the multiplex RFMP assay. Results The multiplex RFMP assay correctly identified known viral sequences with sufficient analytical sensitivity to detect as few as 100 IU/ml of HBV and with superior ability to determine haplotypes composed of neighbouring variations. Complex mutational patterns and relative abundances determined by multiplex RFMP assay were in good concordance with results obtained by direct or clonal sequencing analyses. Defined mixtures were successfully and consistently identified at 2% relative concentration of mutant versus wild-type virus by the assay. Conclusions The multiplex RFMP assay is an accurate and sensitive means to detect entecavir and lamivudine resistance mutations, simultaneously. The method is expected to enable early and efficient diagnosis of multiple drug resistance mutations for optimal management of CHB.

    Abstract: Rapid door-to-balloon times in ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention are associated with favorable outcomes. Objectives: We evaluated the effects of prearrival direct notification calls to interventional cardiologists on door-to-balloon time for ST-elevation myocardial infarction patients undergoing primary percutaneous coronary intervention. Methods: A 24-h hotline was created to allow prearrival direct notification calls to interventional cardiologists when transferring ST-elevation myocardial infarction patients. In an urban, tertiary referral center, patients who visited via inter-facility or the emergency department directly were included. Clinical parameters, time to reperfusion therapy, and in-hospital mortality were compared between patients with and without prearrival notifications. Results: Of 228 ST-elevation myocardial infarction patients, 95 (41.7%) were transferred with prearrival notifications. In these patients, door-to-balloon time was shorter (50.0 vs 60.0 min, p = 0.010) and the proportion of patients with door-to-balloon time  〈  90 min was higher (89.5% vs 75.9%, p = 0.034) than patients without notifications. These improvements were more pronounced during “off-duty” hours (52.0 vs 78.0 min, p = 0.001; 88.3% vs 72.3%, p = 0.047, respectively) than during “on-duty” hours (37.5 vs 43.5 min, p = 0.164; 94.4% vs 79.4%, p = 0.274, respectively). In addition, door-to-activation time (–39 vs 11 min, p  〈  0.001) and door-to-catheterization laboratory arrival time (33 vs 42 min, p = 0.007) were shorter in patients with prearrival notifications than those without. However, in-hospital mortality was similar between the two groups (6.3% vs 6.8%, p = 0.892). Conclusion: Prearrival direct notification calls to interventional cardiologists significantly improved the door-to-balloon time and the proportion of patients with door-to-balloon time 〈  90 min through rapid patient transport in primary percutaneous coronary intervention scheduled hospital and readiness of the catheterization laboratory.
