Abstract
PURPOSE Cytotoxic lesions of corpus callosum (CLOCCs) are associated with many disease entities. Serious neurological complications after coronavirus disease 2019 (COVID-19) vaccination are rare. CASE REPORT A 20-year-old man presented with severe headache for 2 days. He had received the first dose of ChAdOx1nCoV-19 COVID-19 vaccine 5 days ago. Persistent dull headache occurred on the third day after vaccination and intensified gradually to awaken him from sleep at night. No neck stiffness was observed. Brain magnetic resonance angiography (MRA) 9 days after vaccination revealed an oval-shaped diffusion-weighted restriction lesion at the splenium of corpus callosum with a mildly high signal intensity on T2-weighted images (T2WI) and low signal intensity on apparent diffusion coefficient (ADC) imaging but without enhancement after contrast injection. A COVID-19 polymerase chain reaction test was negative. A blood test revealed slight leukocytopenia, thrombocytopenia, and hyponatremia. Further autoimmune and hematological studies were normal. A cerebrospinal fluid study revealed normal intracranial pressure. The patient's headache improved gradually. Follow-up brain MRA 5 weeks after vaccination revealed complete disappearance of the diffusion-weighted restriction lesion of the splenium. CONCLUSION CLOCCs are rare transient adverse effect of COVID-19 vaccination possibly related to a cytokine storm. The splenic lesion might disappear spontaneously with a good prognosis.

Abstract
We investigated the seasonal variations in stroke in 4040 retrospectively enrolled patients with acute ischemic stroke (AIS) admitted between January 2011 and December 2022, particularly those with cardioembolic (CE) stroke, and compared predictors of unfavorable outcomes between AIS patients and CE stroke patients. The classification of stroke subtypes was based on the Trial of ORG 10172 in Acute Stroke Treatment. Stroke occurrence was stratified by seasons and weekdays or holidays. Of all AIS cases, 18% were of CE stroke. Of all five ischemic stroke subtypes, CE stroke patients were the oldest; received the most thrombolysis and thrombectomy; had the highest initial National Institutes of Stroke Scale (NIHSS) and discharge modified Rankin Scale (mRS) scores; and had the highest rate of in-hospital complications, unfavorable outcomes (mRS > 2), and mortality. The highest CE stroke prevalence was noted in patients aged ≥ 85 years (30.9%); moreover, CE stroke prevalence increased from 14.9% in summer to 23.0% in winter. The main predictors of death in patients with CE stroke were age > 86 years, heart rate > 79 beats/min, initial NIHSS score > 16, neutrophil-to-lymphocyte ratio (NLR) > 6.4, glucose > 159 mg/dL, cancer history, in-hospital complications, and neurological deterioration (ND). The three most dominant factors influencing death, noted in not only patients with AIS but also those with CE stroke, are high initial NIHSS score, ND, and high NLR. We selected the most significant factors to establish nomograms for predicting fatal outcomes. Effective heart rhythm monitoring, particularly in older patients and during winter, may help develop stroke prevention strategies and facilitate early AF detection.

Abstract
We conducted a comparative study of two models of point-of-care ultrasound devices for measuring post-void residual urine (PVRU). We prospectively enrolled 55 stroke inpatients who underwent both real-time B-mode ultrasound (Device A) and automated three-dimensional (3D) scanning ultrasound (Device B), with a total of 108 measurements. The median PVRU volume of Device B was 40 mL larger than that of Device A. The PVRU difference between the devices was positively and linearly correlated with PVRU. The correlation of PVRU volume between the devices was strong, but the agreement level was only moderate. Measurement deviations were observed in 43 (40%) and 11 (10%) measurements with Device B and Device A, respectively. The PVRU volume was low in spherical bladder shapes but sequentially increased in triangular, undefined, ellipsoid, and cuboid bladder shapes. Further comparison of 60 sets of PVRU without measurement deviations revealed higher agreements between the devices at correction coefficients of 0.52, 0.66, and 0.81 for PVRU volumes of <100, 100-200, and >200 mL, respectively. The automated 3D scanning ultrasound is more convenient for learning and scanning, but it exhibits larger measurement deviations. Real-time B-mode ultrasound accurately visualizes the urinary bladder but tends to underestimate the urinary bladder when the PVRU volume is large. Hence, real-time B-mode ultrasound with automated PVRU-based adjustment of calculation formulas may be a better solution for estimating bladder volume.

Abstract
The prevalence of carotid stenosis is considerably higher in asymptomatic individuals with multiple risk factors than in the general population. We investigated the validity and reliability of carotid point-of-care ultrasound (POCUS) for rapid carotid atherosclerosis screening. We prospectively enrolled asymptomatic individuals with carotid risk scores of ≥7 who underwent outpatient carotid POCUS and laboratory carotid sonography. Their simplified carotid plaque scores (sCPSs) and Handa's carotid plaque scores (hCPSs) were compared. Of 60 patients (median age, 81.9 years), 50% were diagnosed as having moderate- or high-grade carotid atherosclerosis. The overestimation and underestimation of outpatient sCPSs were more likely in patients with low and high laboratory-derived sCPSs, respectively. Bland-Altman plots indicated that the mean differences between the participants' outpatients and laboratory sCPSs were within two standard deviations of their laboratory sCPSs. A Spearman's rank correlation coefficient revealed a strong positive linear correlation between outpatient and laboratory sCPSs (r = 0.956, p < 0.001). An intraclass correlation coefficient analysis indicated excellent reliability between the two methods (0.954). Both carotid risk score and sCPS were positively and linearly correlated with laboratory hCPS. Our findings indicate that POCUS has satisfactory agreement, strong correlation, and excellent reliability with laboratory carotid sonography, making it suitable for rapid screening of carotid atherosclerosis in high-risk patients.

Abstract
BACKGROUND Esthetic upper lateral cutaneous lip reconstruction preserves the apical triangle, nasolabial fold symmetry, and free margin position. The tunneled island pedicle flap (IPF) is a novel single-stage reconstruction to achieve these goals. OBJECTIVES Describe the technique and patient and surgeon-reported outcomes for the tunneled IPF reconstruction of upper lateral cutaneous lip defects. METHODS Retrospective chart review of consecutive tunneled IPF reconstruction following Mohs micrographic surgery (MMS) at a tertiary care center between 2014 and 2020. Patients rated their scars using the validated Patient Scar Assessment Scale (PSAS), and independent surgeons rated scars using the validated Observer Scar Assessment Scale (OSAS). Descriptive statistics were generated for patient demographics and tumor defect characteristics. RESULTS Twenty upper lateral cutaneous lip defects were repaired with the tunneled IPF. Surgeons rated scars with a composite OSAS score of 11.83 ± 4.29 (mean, SD) [scale of 5 (normal skin) to 50 (worst scar imaginable)] and an overall scar score of 2.81 ± 1.11 [scale of 1 (normal skin) to 10 (worst scar imaginable)]. Patients rated their scars with a composite PSAS score of 10 ± 5.39 [scale of 6 (best possible score) to 60 (worst)] and with an overall score of 2.2 ± 1.78 [scale of 1 (normal skin) and 10 (very different from normal skin)]. One flap was surgically revised for pincushioning, but none experienced necrosis, hematoma, or infection. CONCLUSIONS The tunneled IPF is a single-stage reconstruction for upper lateral cutaneous lip defects with favorable scar ratings by patients and observers.

Abstract
PURPOSE The three-dimensional (3D) measurement of vessel wall volume (VWV) and plaque volume is sensitive for predicting cardiovascular risk. We established the normal norms of carotid VWV. METHODS We retrospectively enrolled 352 patients with normal findings of the carotid ultrasound studies. Two-dimensional carotid intima-media thickness (IMT) was measured online. Grayscale 3D images of both sides of the carotid arteries were analyzed offline for measurement of IMT (QIMT) and VWV. RESULTS The median age of the enrollees was 59 years. The median carotid IMT, QIMT, and VWV was 0.61 mm, 0.72 mm, and 90 mm3, respectively. No differences in IMT and VWV were observed between men and women or between the right and left side. We stratified participants into four groups, namely young adults (≤50 years), middle-aged adults (51-65 years), older adults (66-75 years), and senior adults (≥75 years). All the values of measured variables increased with advancing age. The median VWV of each group was 84, 90, 100, and 112 mm3, respectively. The increment percentage from young to senior adults was similar in terms of IMT and VWV. Nevertheless, the difference in the value of VWV (28 mm3) was much larger than that in IMT (0.18 mm). All three measured variables exhibited a positive linear correlation with age. CONCLUSION Both IMT and VWV have positive linear correlations with age. The application of QIMT measurements was limited by its inconsistent accuracy. VWV not only has a strong correlation with IMT but also enables observation of dynamic vessel wall changes, which is valuable for clinical observational studies.

Abstract
PURPOSE Takotsubo syndrome (TTS) is characterized angiographically by transient left ventricular systolic dysfunction sparing the basal segments of the left ventricle and absence of obstructive coronary artery disease. Epileptic seizures as triggering events for TTS are uncommon, having only been described in approximately 100 previous cases Case report: A 64-year-old woman with a history of recent stroke-related seizures was admitted for an acute onset of right hemiparesis with dull response. Neurological examination revealed a forced deviation of the eyeballs to the left side and quadriplegia. No large intracranial artery occlusion was disclosed through computed tomography angiography, but an acute infarction at the right corona radiata was identified through magnetic resonance imaging. Electroencephalography showed frequent spike-and-wave complexes over the right cerebral hemisphere indicating subtle status epilepticus. Her consciousness deteriorated to a stuporous state, and her eyeballs were forced deviated to the right side with persistent twitching of the right limbs 10 hours later. The convulsive status epilepticus (CSE) subsided after intravenous infusion of midazolam. However, atrial flutter with inverted T-wave and elevated high-sensitivity troponin I were observed 12 hours after CSE. Arrhythmia was soon alleviated through appropriate treatment. A further coronary angiography did not show significant coronary artery stenosis but indicated that the midsection and the apex of the left ventricle ballooned out during systole as the base contracted normally, indicating a Takotsubo syndrome. CONCLUSION Physicians need to monitor unusual arrhythmias, particularly atrial and ventricular arrhythmias, for the possibility of TTS in patients with epileptic seizure.

Abstract
Carotid atherosclerosis is associated with cardiovascular and cerebrovascular events. We explored an appropriate method for selecting participants without ischemic cerebrovascular disease but with various comorbidities eligible for a carotid ultrasound. This was a retrospective subgroup analysis of the carotid plaque burden from a previous study involving a vascular and cognitive survey of 956 elderly recycling volunteers (778 women and 178 men; mean age: 70.8 years). We used carotid ultrasound to detect the carotid plaque and computed the carotid plaque score (CPS). A moderate or high degree of carotid atherosclerosis (MHCA) was defined as CPS > 5 and was observed in 22% of the participants. The CPS had positive linear correlations with age, systolic blood pressure, and fasting glucose. We stratified the participants into four age groups: 60−69, 70−74, 75−79, and ≥80 years. Multivariable analysis revealed that significant predictors for MHCA were age, male sex, hypertension, diabetes mellitus, hyperlipidemia, coronary artery disease, and a nonvegetarian diet. Coronary artery disease and advanced age were the two strongest predictors. We chose the aforementioned seven significant predictors to establish a nomogram for MHCA prediction. The area under the receiver operating characteristic curve in internal validation with 10-fold cross-validation and the classification accuracy of the nomogram were 0.785 and 0.797, respectively. We presumed people who have a ≥50% probability of MHCA warranted a carotid ultrasound. A flowchart table derived from the nomogram addressing the probabilities of all models of combinations of comorbidities was established to identify participants who had a probability of MHCA ≥ 50% (corresponding to a total nomogram score of ≥15 points). We further established a carotid risk score range from 0 to 17 comprising the seven predictors. A carotid risk score ≥ 7 was the most optimal cutoff value associated with a probability of MHCA ≥ 50%. Both total nomogram score ≥ 15 points and carotid risk score ≥ 7 can help in the rapid identification of individuals without stroke but who have a ≥50% probability of MHCA—these individuals should schedule a carotid ultrasound.

Abstract
(1) Background: We investigated the association of four immune-inflammatory markers with clinical features and established location-specific nomograms to predict mortality risk in patients with intracerebral hemorrhage (ICH). (2) Methods: We retrospectively enrolled 613 inpatients with acute ICH. (3) Results: Overall mortality was 22%, which was highest in pontine hemorrhage and lowest in thalamic hemorrhage. All four immune-inflammatory markers exhibited a positive linear correlation with glucose, ICH volume, ICH score, and discharge Modified Rankin Scale (mRS) score. Significant predictors of death due to lobar/putaminal hemorrhage were age, glucose and creatinine levels, initial Glasgow Coma Scale (GCS) score, ICH volume, and presence of intraventricular hemorrhage. None of the immune-inflammatory markers were significant predictors of unfavorable outcome or death. We selected significant factors to establish nomograms for predicting death due to lobar/putaminal, thalamic, pontine, and cerebellar hemorrhages. The C-statistic for predicting death in model I (comprising factors in the establishment of the nomogram) in each type of ICH was higher than that in model II (comprising ICH score alone), except for cerebellar hemorrhage. These nomograms for predicting death had good discrimination (C-index: 0.889 to 0.975) and prediction probabilities (C-index: 0.890 to 0.965). (4) Conclusions: Higher immune-inflammatory markers were associated with larger ICH volume, worse initial GCS, and unfavorable outcomes, but were not independent prognostic predictors. The location-specific nomograms provided novel and accurate models for predicting mortality risk.

Abstract
Background The triglyceride-glucose (TyG) index has recently been proposed as a reliable marker of insulin resistance. There is insufficient evidence to verify that the TyG index is correlated with functional outcomes and hemorrhagic transformation and in patients with stroke treated with intravenous thrombolysis (IVT). Methods We designed a multicenter cohort study, which enrolled patients with acute ischemic stroke treated with IVT between December 2004 and December 2016. The TyG index was divided into tertiles and calculated on a continuous scale. Unfavorable functional outcomes were defined by the modified Rankin Scale of 3–6 at 90 days and the incident rates of symptomatic intracranial hemorrhage (SICH) within 36 h of IVT onset were surveyed. Stroke severity was defined as mild (4–8), moderate (9–15), or high (≥16) based on the National Institutes of Health Stroke Scale (NIHSS) scores. Results Among 914 enrolled patients, the tertiles of the TyG index were 8.48 for T1, 8.48–9.04 for T2, and 9.04 for T3. T3 showed an increased risk of unfavorable functional outcomes at 90 days [odds ratio (OR): 1.76; P = 0.0132]. The TyG index was significantly associated with unfavorable functional outcomes at 90 days (OR: 1.32; P = 0.0431 per unit increase). No association was found between the TyG index and SICH. These findings were applicable for T3 with stroke of moderate (OR, 2.35; P = 0.0465) and high severity (OR: 2.57, P = 0.0440) patients with stroke. Conclusion This study supports the strong association between the increased TyG index and increased unfavorable functional outcomes at 90 days in patients with acute ischemic stroke treated with IVT. These findings were found to be robust in patients with moderate and high stroke severity.

Abstract
Background Insufficient evidence is available for patients with acute ischemic stroke with atrial fibrillation (AF) to determine the efficacy and safety of different dosages of intravenous thrombolysis treatment. This study examined clinical outcomes in Chinese patients with stroke with and without AF after intravenous thrombolysis treatment with different intravenous thrombolysis doses. Methods and Results This multicenter, prospective cohort study recruited 2351 patients with acute ischemic stroke (1371 with AF and 980 without AF) treated with intravenous thrombolysis using alteplase. The Totaled Health Risks in Vascular Events score is a validated risk‐scoring tool used for assessing patients with acute ischemic stroke with and without AF. We evaluated favorable functional outcome at day 90 and symptomatic intracranial hemorrhage within 24 to 36 hours and outcomes of the patients receiving different doses of alteplase. Compared with the non‐AF group, the AF group exhibited a 2‐ to 3‐fold increased risk of symptomatic intracranial hemorrhage according to the National Institute of Neurological Disorders and Stroke standard (relative risk [RR], 2.10 [95% CI, 1.35–3.26]). Favorable functional outcome at 90 days and symptomatic intracranial hemorrhage rates according to the European Cooperative Acute Stroke Study II and the Safe Implementation of Thrombolysis in Stroke‐Monitoring Study standards did not significantly differ between the AF and non‐AF groups. In addition, the low‐dose alteplase subgroup exhibited an increased risk of symptomatic intracranial hemorrhage according to the National Institute of Neurological Disorders and Stroke standard (RR, 2.84 [95% CI, 1.63–4.96]). A validation study confirmed these findings after adjustment for scores determined using different stroke risk‐scoring tools. Conclusions Different alteplase dosages did not affect functional status at 90 days in the AF and non‐AF groups. Thus, the adoption of low‐dose alteplase simply because of AF is not recommended.

Abstract
Objectives: The intima–media thickness (IMT) of the carotid artery can now be detected on a three-dimensional (3D) plane. The 3D vessel wall volume (VWV) more accurately represents vascular conditions. Through 3D ultrasound, we established a standardized method for carotid VWV measurement. Materials and Methods: A total of thirty patients without stroke or cardiovascular disease who received carotid duplex sonography were retrospectively reviewed. Gray-scale 3D images from the distal common carotid artery (CCA) to internal carotid artery on both sides were acquired using a single-sweep 3D transducer and analyzed offline by using the vascular plaque quantification function of the Philips QLAB software. Then, the 3D IMT(QLAB intima–media thickness [QIMT]), total plaque volume (TPV), and VWV were measured by a neurologist and a technician, and the interobserver variability was assessed. Results: The mean two-dimensional (2D) carotid IMT was 0.65 ± 0.12 mm. The mean QIMT, TPV, and VWV measured by observer 1 were 0.68 ± 0.18 mm, 26 ± 12 mm3, and 94 ± 10 mm3, respectively. The Bland–Altman plot of the mean differences between the QIMT, TPV, and VWV values measured by observers 1 and 2 showed that those of observer 2 were within two standard deviations of those of observer 1. Intraclass correlation coefficients (ICCs) indicated strong correlations in QIMT (ICC = 0.76), TPV (ICC = 0.85), and VWV (ICC = 0.90; P < 0.001) between observers 1 and 2. Both 2D IMT and 3D QIMT exhibited a positive linear correlation with age. Conclusion: This study established a standardized VWV measurement through 3D ultrasound. Reasonable interobserver differences were obtained within a 95% limit of agreement and high reliability (ICC = 0.90). The VWV 1 cm from the CCA bifurcation was quantified with a mean value of 94.2 mm3. Further studies on the 3D ultrasound quantification of carotid arteries are warranted.

Abstract
PURPOSE Occlusion of both internal carotid arteries (ICAs) is rare. Clinical manifestations of stroke vary widely. We conducted a retrospective review to compare acute and chronic bilateral ICA occlusion. METHODS We retrospectively reviewed records of inpatients with acute ischemic stroke and carotid duplex sonography (CDS) during the period from February 2006 to February 2021. RESULTS Bilateral ICA occlusion and acute bilateral ICA occlusion accounted for 0.3% and less than 0.1% of all ischemic stroke cases, respectively. All five patients with acute bilateral ICA occlusion presented with consciousness disturbance. Three patients died within 1 week, and two patients had a vegetative outcome. Pituitary apoplexy with bilateral ICA occlusion was observed in one patient. Forward bilateral ophthalmic arterial flow (OAF) was detected in all three patients who received CDS. Among 13 patients with chronic bilateral ICA occlusion, five and six had modified Rankin Scale (mRS) scores upon discharge of more than 5 and less than 2, respectively; two patients did not have a stroke. Of the 13 patients, 11 had reversed bilateral OAF. Patients with acute bilateral ICA occlusion had a higher rate of initial consciousness disturbance, Glasgow Coma Scale score of less than 9, National Institute of Health Stroke Scale score of more than 20, and mRS score of more than 5. than that of patients with chronic bilateral ICA occlusion. CONCLUSION Patients with acute bilateral ICA occlusion had higher initial stoke severity, poorer collateral circulation, and worse clinical outcomes than did those with chronic bilateral ICA occlusion. Physicians must pay attention to rare causes of acute bilateral ICA occlusion, including pituitary apoplexy.

Abstract
Background In addition to nerve conduction studies (NCSs), ultrasonography has been widely used as an alternative tool for diagnosing carpal tunnel syndrome (CTS). Although the results of NCSs are influenced by local skin temperature, few studies have explored the effects of skin temperature on ultrasonography of the median nerve. Since swelling and intraneural blood flow of the median nerve might be influenced by local temperature changes, the aim of this study was to evaluate the cross-sectional area (CSA) and intraneural blood flow of the median nerve under three skin temperatures (30 °C, 32 °C, 34 °C). Methods Fifty patients with CTS and 50 healthy volunteers were consecutively recruited from a community hospital. Each participant received physical examinations and NCSs and underwent ultrasonography, including power Doppler, to evaluate intraneural vascularity. Results The CSA of the median nerve in the CTS patients was significantly larger than that in the healthy controls at all three temperatures. However, significant differences in the power Doppler signals of the median nerve between the two studied groups were observed only at 30 and 32 °C, not at 34 °C. Conclusion The significant difference in the intraneural vascularity of the median nerve between the patients with CTS and the healthy subjects was lost at higher temperatures (34 °C). Therefore, the results of power Doppler ultrasonography in diagnosing CTS should be cautiously interpreted in patients with a high skin temperature or those who reside in warm environments.

Abstract
The artery of Percheron (AOP) is an anatomical variant of the thalamoperforating arteries. AOP occlusion can cause bilateral paramedian thalamic infarctions and is referred to as a "stroke chameleon" because it lacks the classic signs of stroke. Coexistence of AOP occlusion and other neurologic disease is rare and can cause disturbance of consciousness. A 78-year-old woman had acute onset of left limb weakness and drowsy consciousness. Brain magnetic resonance angiography (MRA) revealed acute bilateral paramedian thalamic infarctions. However, serum and cerebrospinal fluid (CSF) cryptococcal antigen titers were 1:16 and 1:128, respectively. The CSF culture grew Cryptococcus neoformans. Although consciousness and muscle power improved after treatment, the patient later died of pneumonia. A 68-year-old woman developed acute disturbance of consciousness followed by delirium. Brain MRA revealed acute bilateral paramedian thalamic infarctions. Elevated free thyroxine, anti-thyroperoxidase, and anti-thyroglobulin antibodies were detected. She received 3 days of steroid pulse therapy followed by oral prednisolone. Her consciousness gradually improved after Hashimoto encephalopathy and stroke were controlled. AOP occlusion was diagnosed early in these two patients. However, other concomitant life-threatening diseases could have been overlooked because of the complicated diagnostic determination. Further serum cryptococcal antigen, anti-TPO Ab, and anti-TG Ab surveys might help to exclude cryptococcal meningitis and Hashimoto encephalopathy. CSF study is warranted when central nervous system infection is strongly suspected. This "Percheron artery-plus syndrome" comprises multifaceted disorders beyond the stroke chameleon and requires attention.

Abstract
Background: This study aimed to investigate the safety and efficacy of single antiplatelet, anticoagulant and Dual Antiplatelet pre-treatment (DAPP) in older, moderate to high severity acute ischemic stroke patients treated with intravenous thrombolysis (IVT). Methods: A prospective cohort study was conducted to monitor the development of symptomatic intracranial hemorrhage (SICH) and functional outcomes at 90 days. Two different dosages of alteplase were used for IVT. Logistic regression models were used for analysis of the safety and efficacy outcomes. Results: A total of 1,156 patients were enrolled and categorized into six groups based on their pre-treatment medications: (1) aspirin (n = 213), (2) clopidogrel (n = 37), (3) DAPP of aspirin + clopidogrel (n= 27), (4) warfarin (n = 44), (5) any of the above pre-medications (n = 331), and (6) none of these medications as controls (n = 825). The DAPP group showed significantly increased SICH by the NINDS (adjusted OR: 4.90, 95% CI 1.28-18.69) and the ECASS II (adjusted OR: 5.09, 95% CI: 1.01-25.68) standards. The aspirin group was found to significantly improve the favorable functional outcome of the modified Rankin Scale (mRS) of 0-1 (adjusted OR: 1.91, 95% CI, 1.31.2.78), but no significance for mRS of 0-2 (adjusted OR: 1.39, 95% CI, 0.97-1.99). The DAPP group also significantly increased mortality (adjusted OR: 4.75, 95% CI: 1.77-12.72). A significant interaction between different dosages for IVT and the functional status was noted. Compared to standard dose, the DAPP group showed higher proportions of disability and mortality with low dose of IVT. Conclusion: For older adults with higher baseline severity of acute ischemic stroke, DAPP may increase the risk of SICH and mortality post IVT. However, DAPP is still not an indication to withdraw IVT and to prescribe low-dose IVT for older adults.

Abstract
Purpose Immune–inflammatory processes are involved in all the stages of stroke. This study investigated the association of the neutrophil-to-lymphocyte ratio (NLR) with the hyperdense artery sign (HAS) observed on brain computed tomography (CT) and with clinical features in patients with acute ischemic stroke. Methods We retrospectively enrolled 2903 inpatients with acute ischemic stroke from May 2010 to May 2019. Data collected included imaging studies, risk factors, laboratory parameters, and clinical features during hospitalization. Results The HAS was identified in 6% of the 2903 patients and 66% of the 236 patients with acute middle cerebral artery occlusion. Patients with the HAS had a higher NLR. HAS prevalence was higher in men and patients with cardioembolism. The NLR exhibited positive linear correlations with age, glucose and creatinine levels, length of hospital stay, initial National Institutes of Health Stroke Scale (NIHSS) scores, and mRS scores at discharge. The NLR was significantly higher in patients with large-artery atherosclerosis and cardioembolism and was the highest in patients with other determined etiology. Multivariate analysis revealed that an initial NIHSS score of ≥10 and an NLR of >3.5 were significant positive factors, whereas diabetes mellitus and age > 72 years were significant negative factors for the HAS, with a predictive performance of 0.893. An initial NIHSS score of ≥5, positive HAS, age > 75 years, diabetes mellitus, an NLR of >3.5, female sex, a white blood cell count of >8 × 103/mL, and elevated troponin I were significant predictors of unfavorable outcomes, with a predictive performance of 0.886. Conclusion An NLR of >3.5 enabled an efficient prediction of CT HAS. In addition to conventional risk factors and laboratory parameters, both an NLR of >3.5 and CT HAS enabled improved prediction of unfavorable stroke outcomes.

Abstract
OBJECTIVE Chronic inflammatory processes involving the vascular wall may induce atherosclerosis. Immune-inflammatory processes proceed throughout all stages of acute stroke. We investigated the association of three immune-inflammatory markers, namely systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and neutrophil count (NC), with prehospital delay and clinical features in patients with acute ischemic stroke. METHODS We retrospectively enrolled 2543 inpatients admitted within 4 days of symptom onset from May 2010 to February 2020. Patients were stratified into three groups: Group A, comprising 161 patients with tissue plasminogen activator (tPA) treatment; Group B, comprising 415 patients who were eligible for tPA treatment; and Group C, comprising all 2543 patients. RESULTS The levels of all three immune-inflammatory markers had positive linear correlations with onsetto- emergency room time, initial National Institutes of Health Stroke Scale (NIHSS) scores, and discharge modified Rankin Scale scores. In Group B, levels of follow-up, but not initial, immuneinflammatory markers were higher in patients with unfavorable outcomes. Common significant predictors of in-hospital complications and unfavorable outcomes were age > 72 years, female sex, NIHSS > 4, diabetes mellitus, and all three immune-inflammatory markers. When combined with other predictors, NC > 7.2 × 103/mL achieved optimal predictive performance (0.794) for in-hospital complications, and SII > 651, NLR > 2.9, and NC > 7.2 × 103/mL had equal predictive performance up to 0.859 for unfavorable outcomes. CONCLUSIONS Immune-inflammatory markers dynamically increased from symptom onset of acute ischemic stroke in patients eligible for thrombolytic therapy. Higher levels of immune-inflammatory markers suggest more in-hospital complications and unfavorable short-term outcomes.

Abstract
Background A lower level of consciousness is a common presentation in critical care, with many different causes and contributory factors, of which more than one may be present concurrently. Case presentation We described a woman with poorly controlled diabetes and steroid-dependent asthma who presented in a deep coma. She was found to have Streptococcus intermedius bacteremia and pyogenic ventriculitis that originated from right middle lobe pneumonia. Also, multiple small parenchymal lesions were observed on brain magnetic resonance imaging and increased protein concentration was noted in cerebral spinal fluid. Initially, her coma was thought to be due to diabetic ketoacidosis and septic encephalopathy. However, her lowered level of consciousness was disproportionate to either diabetic ketoacidosis or septic encephalopathy, and her clinical course was not as expected for these two conditions. Treatment with antibiotic, corticosteroid and antihelminthic drugs was administered resulting in improving consciousness. The Streptococcus intermedius pneumonia progressed to form a large cavity that needed an early surgical lobectomy and resulted in the unexpected diagnosis of chronic cavitary pulmonary aspergillosus. Conclusions In critical care, a lowered level of consciousness may have many etiologies, and critical care clinicians should be familiar with the signs and symptoms of all possible causes to enable prompt diagnosis and appropriate treatment.

Abstract
Objectives The National Health Insurance Bureau of Taiwan has established a postacute care model of stroke (PAC-stroke). Patients with acute stroke occurring within the preceding 30 days and with modified Rankin scale (mRS) scores of 2-4 can be transferred to PAC hospitals for 6-12 weeks of rehabilitation. We conducted a retrospective review to explore the results of PAC-stroke. Materials and Methods From April 2015 to December 2017, patients who transferred from our hospital to four PAC hospitals were reviewed. We evaluated their functional status using the mRS, Barthel index (BI), functional oral intake scale, EuroQoL-5D, Lawton-Brody instrumental activities of daily living scale, Berg balance test, usual gait speed, 6-min walk test, Fugl-Meyer sensory and motor assessments, mini-mental state examination, motor activity log quantity and quality tests, and concise Chinese aphasia test, before and after the PAC program. Results A total of 53 patients with initial mRS score of 3 (6 patients) or 4 (47 patients) were enrolled, including 39 with cerebral infarction and 14 with cerebral hemorrhage, with a median age of 67 (mean: 68.3 ± 13.3) years. Seven patients had serious complications, including six cases of pneumonia and one fracture. The readmission rates within 14 days after transfer to the PAC hospital and in the overall PAC program were 3.8% and 13.2%, respectively. After exclusion of eight patients who dropped out early, 45 patients completed the PAC program. The median lengths of stay at the upstream hospital and PAC hospitals were 26 and 63 days, respectively. Improved mRS and BI scores were observed in 42% and 78% of the patients, respectively. The results of all 14 functional assessments improved significantly after the PAC program. Conclusion Significant improvements in mRS and BI scores and all functional assessments within an average of 63 days of PAC hospital stay helped 73% of the patients to return home.

Abstract
BACKGROUND Urinary tract infection (UTI) during acute ischemic stroke is associated with a longer hospital length of stay and unfavorable functional outcomes. OBJECTIVE We investigated the benefits of portable bladder ultrasound (PBU) scanning during acute ischemic stroke. METHODS We retrospectively reviewed patients with acute ischemic stroke from January 2011 to February 2017. Patients were divided into group 1 (PBU not available) and group 2 (PBU available), before or after the split date, April 9, 2014. Portable bladder ultrasound scanning was conducted by nurses to measure postvoid residual urine volume in patients with impaired consciousness and/or dependent ambulation. RESULTS In total, 1928 patients were enrolled, of whom 109 (5.7%) had UTI and 901 (46.7%) experienced unfavorable outcomes (modified Rankin scale score ≥ 3). Multivariate analysis revealed that factors that influenced UTI were age of 75 years or older, female gender, initial total National Institutes of Health Stroke Scale (NIHSS) score of 5 or higher, initial NIHSS conscious score of 1 or higher, initial NIHSS leg score of 2 or higher, and urinary catheterization. Factors influencing unfavorable outcomes were similar to those influencing UTI but further comprised UTI. C-statistic for UTI detection was 0.864 for model fitting, including significant factors in logistic regression. Compared with group 1, group 2 had a higher incidence of urinary catheterization (13.1% vs 8.2%), a lower incidence of UTI (4.0% vs 6.9%), and a shorter length of stay (11.9 vs 13.6 days). CONCLUSIONS Portable bladder ultrasound scanning reduced the incidence of UTI and shortened length of stay. We suggest routine PBU procedures for patients with acute ischemic stroke who fulfill the AGN3 criteria for a high risk of UTI.

Abstract
Intracranial dural arteriovenous fistula (DAVF) with perimedullary venous drainage may cause brainstem swelling and represent a diagnostic challenge. A 66-year-old man presented to the emergency room with recurrent vertigo, minimal truncal ataxia with a wide-based gait, and a slightly impaired tandem gait. Brain magnetic resonance imaging (MRI) revealed a hyperintense lesion in the left pontomedullary area on T2-weighted images (T2WIs) with partial gadolinium enhancement, but without increased signals on diffusion-weighted images. Abnormal serpentine flow void vessels surrounding the medulla and upper cervical spinal cord were initially overlooked but discovered later. An angiogram revealed DAVF with feeders from the right occipital artery and the meningeal branch of the right distal vertebral artery with drainage into the anterior medullary venous system and the perimedullary veins. The patient underwent a successful transarterial endovascular embolization and improved gradually. A brain MRI at 3-month follow-up revealed a residual hyperintense signal on the T2WIs in the left lower medulla. Six cases of patients exhibiting DAVF with isolated unilateral brainstem swelling from the literature were reviewed. Isolated unilateral brainstem swelling due to intracranial DAVF with perimedullary venous drainage is extremely rare and might mimic a tumor on MRI. Abnormal serpentine flow void vessels on the surface of the brainstem or spinal cord are crucial diagnostic clues.

Abstract
BACKGROUND AND PURPOSE The optimal dose of alteplase for acute ischemic stroke among geriatric patients is unclear. We aimed to assess the efficacy and safety of a low-dose (0.6 mg/kg) and standard-dose (0.9 mg/kg) alteplase for varying severity of Asian geriatric stroke patients. METHODS The favorable functional outcome on day 90 after stroke onset, and the symptomatic intracranial hemorrhage (SICH) rate following 24-36 h of intravenous alteplase were measured. The baseline NIHSS of 4-8, 9-13, ≥14 were defined as mild, moderate, and high severity, respectively. RESULTS Totally, 249 geriatric patients treated with low-dose (n = 108) and standard-dose (n = 141) alteplase. Compared to standard-dose alteplase, low-dose alteplase had decrease in favorable functional outcome (22.2% versus 34.8%), and no difference in SICH rates was observed. For mild severity patients, the mortality was significantly increased with standard-dose alteplase (the NNT/NNH = 22.9/8.0 for mild severity, the NNT/ NNH = 15.0/14.7 for moderate severity, and the NNT/NNH = 13.5/19.6 for high severity). CONCLUSIONS Standard-dose and low-dose alteplase were comparable in reducing major disability, but low-dose alteplase for mild stroke showed much reduced mortality on day 90 for octogenarians.

Abstract
Background: Stroke and dementia represent frequent causes of psychophysical and socioeconomic burdens. We conducted a vascular, cognitive, and psychomental survey involving elderly volunteers at community-based recycling stations in Northern Taiwan. Methods: Recycling volunteers aged ≥60 years were surveyed. We recorded seven parameters, namely (1) body mass index (BMI), (2) fasting glucose, (3) fasting cholesterol, (4) ankle-brachial index (ABI), (5) carotid duplex sonography, (6) five-item Brief Symptom Rating Scale (BSRS-5) score, and (7) eight-item Interview to Differentiate Aging and Dementia (AD8). During the carotid duplex study, we measured the carotid intima-media thickness (CIMT) and the carotid total plaque score (CTPS) of the common and internal carotid arteries. Results: In total, 985 subjects (mean age: 70.8 years) participated in this study. Among these, 81% were women, and 52% were vegetarians. The average ABI, CIMT, and CTPS were higher in men, whereas women had higher cholesterol levels and BSRS-5 scores. Obesity, hypertension, hyperglycemia, and hyperlipidemia were present in 21, 38, 9, and 27% of all subjects, respectively. Carotid plaques with mild (CTPS 1–5), moderate (CTPS 5.1–10), and severe (CTPS > 10) atherosclerosis were detected in 45, 16, and 7% of the subjects, respectively. Mild cognitive impairment (AD8 > 2) was observed in 13% of the subjects, whereas moderate mood disorder (BSRS-5≧10) was observed in only 1% of subjects. Vegetarians had a lower BMI, systolic blood pressure (SBP), cholesterol, CIMT, and CTPS than did non-vegetarians. Substantial predictors of severe atherosclerosis were advanced age (>70 years), male sex, history of heart disease, hyperlipidemia, and currently elevated SBP and cholesterol levels. Predictors of mild cognitive impairment were illiteracy, history of hypertension, hyperlipidemia, and moderate mood disorder. Conclusions: Subclinical carotid atherosclerosis was common in elderly recycling volunteers, with 23% having moderate to severe stenosis. Vegetarians had a reduced risk of atherosclerosis. The low incidence of moderate mood disorder might indicate that recycling work enhances psychomental health. In addition, a healthier lifestyle, better mood condition, and vegetarian diet might contribute to lower incidence of mild cognitive impairment.

Abstract
We report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ν[over ¯]_{e} inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic ^{9}Li and ^{8}He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ν[over ¯]_{e} rates and energy spectra among detectors yields sin^{2}2θ_{13}=0.0856±0.0029 and Δm_{32}^{2}=(2.471_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the normal hierarchy, and Δm_{32}^{2}=-(2.575_{-0.070}^{+0.068})×10^{-3} eV^{2} assuming the inverted hierarchy.

Abstract
AIM Although a lower level of non-high-density lipoprotein cholesterol (HDL-C) was reported to be inversely associated with spontaneous intracranial hemorrhage (ICH), no enough evidence has verified whether lipid profiles modify hemorrhagic transformation and functional outcomes in patients with acute ischemic treated with thrombolysis. METHODS This multicenter cohort study included 2373 patients with acute ischemic stroke treated with intravenous thrombolysis between December 2004 and December 2016. Of these, 1845 patients were categorized into either the hyperlipidemia or non-hyperlipidemia group. Symptomatic ICH (SICH) rates within 24-36 h of thrombolytic onset and functional outcomes at 30 and 90 days were longitudinally surveyed. Models of predicting hemorrhagic transformation were used to validate our findings. RESULTS For enrolled 1845 patients, SICH rates were ≥2-fold reduced for the hyperlipidemia group by the NINDS (adjusted RR: 0.488 [0.281-0.846], p=0.0106), the ECASS II (adjusted RR: 0.318 [0.130-0.776], p=0.0119), and SITS-MOST standards (adjusted RR: 0.214 [0.048-0.957], p=0.0437). The favorable functional rates between the two groups were not significantly different. Lower levels of LDL-C were showed in robust association with SICH. With a cut-off LDL-C value of <130 mg/dL, new models are more robust and significant in predicting hemorrhagic transformation within 24-36 h. CONCLUSIONS This study supports the strong association between reduced LDL-C and increased SICH, but not for functional outcomes in patients with acute ischemic stroke treated with intravenous thrombolysis. LDL-C level of <130 mg/dL is supposed to a candidate marker for predicting SICH within 24-36 h.

Abstract
BACKGROUND Efficacy of thrombolytic therapy decreases with time elapsed from symptom onset. We sought to identify the impact of code stroke on the thrombolytic therapy. METHODS Code stroke is activated by the emergency physician when a patient is eligible for thrombolytic therapy. We retrospectively reviewed patients with acute ischemic stroke between January 2011 and December 2014. RESULTS In total, 1809 patients were enrolled. Code stroke was activated in 233 of 351 patients arriving at the emergency room (ER) within 3 h of symptom onset, and in 21 patients arriving >3 h. The sensitivity, specificity, and positive and negative predictive values of code stroke were 76%, 46%, 72%, and 51%, respectively. Thrombolytic therapy was provided to 58 patients, accounting for 3.4% of all cerebral infarcts. Code stroke was activated in 40 of these patients. The most common reasons for excluding thrombolytic therapy were: National Institute of Health Stroke Scale (NIHSS) < 6, intracranial hemorrhage (ICH), and age >80 years. Mean liaison-to-neurological evaluation time was only 6 min. Code stroke activation significantly reduced all the intervals, except for the onset-to-ER and door-to-order times. During the 4-year study period, there were significant reductions of the door-to-neurology liaison time by 28 min and door-to-laboratory time by 22 min. The proportion of door-to-needle time within 60 min improved from 33% in 2011 to 67% in 2014. Improved NIHSS scores during hospitalization were most prominent in tPA-treated patients. Symptomatic ICH occurred in 3.6% patients arriving within 3 h. Death occurred in 50% of patients received tPA treatment on family's request, and only 13% of those patients had favorable outcome. CONCLUSION Code stroke is effective in reducing in-hospital delays. The accuracy of code stroke activation has acceptable sensitivity but low specificity. Rapid patient assessment by neurologists increases the number of patients eligible for thrombolytic therapy.

Abstract
ABSTRACT Treatment-emergent central sleep apnea has recently been noted after various treatment modalities for obstructive sleep apnea. It often remits spontaneously or can be treated with continuous positive airway pressure. However, we encountered a pediatric patient with obstructive sleep apnea who presented with severe complications, including growth failure, attention-deficit hyperactivity disorder, poor school performance, daytime sleepiness, and urinary difficulty that required permanent cystostomy. His obstructive sleep apnea resolved after adenotonsillectomy. However, treatment-emergent central sleep apnea developed after adenotonsillectomy and was further aggravated after continuous positive airway pressure and bilevel positive airway pressure without a backup respiratory rate use. After bilevel positive airway pressure with a backup respiratory rate treatment for 3 months initially, all his symptoms improved, except growth failure. Later, after adaptive servoventilation was used for 10 months, the patient's growth began to improve.

Abstract
The Daya Bay experiment has observed correlations between reactor core fuel evolution and changes in the reactor antineutrino flux and energy spectrum. Four antineutrino detectors in two experimental halls were used to identify 2.2 million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles for each of six 2.9 GW_{th} reactor cores at the Daya Bay and Ling Ao nuclear power plants. Using detector data spanning effective ^{239}Pu fission fractions F_{239} from 0.25 to 0.35, Daya Bay measures an average IBD yield σ[over ¯]_{f} of (5.90±0.13)×10^{-43} cm^{2}/fission and a fuel-dependent variation in the IBD yield, dσ_{f}/dF_{239}, of (-1.86±0.18)×10^{-43} cm^{2}/fission. This observation rejects the hypothesis of a constant antineutrino flux as a function of the ^{239}Pu fission fraction at 10 standard deviations. The variation in IBD yield is found to be energy dependent, rejecting the hypothesis of a constant antineutrino energy spectrum at 5.1 standard deviations. While measurements of the evolution in the IBD spectrum show general agreement with predictions from recent reactor models, the measured evolution in total IBD yield disagrees with recent predictions at 3.1σ. This discrepancy indicates that an overall deficit in the measured flux with respect to predictions does not result from equal fractional deficits from the primary fission isotopes ^{235}U, ^{239}Pu, ^{238}U, and ^{241}Pu. Based on measured IBD yield variations, yields of (6.17±0.17) and (4.27±0.26)×10^{-43} cm^{2}/fission have been determined for the two dominant fission parent isotopes ^{235}U and ^{239}Pu. A 7.8% discrepancy between the observed and predicted ^{235}U yields suggests that this isotope may be the primary contributor to the reactor antineutrino anomaly.

Abstract
The relationship between cholesterol level and hemorrhagic stroke is inconclusive. We hypothesized that low cholesterol levels may have association with intracerebral hemorrhage (ICH) severity at admission and 3-month outcomes. This study used data obtained from a multi-center stroke registry program in Taiwan. We categorized acute spontaneous ICH patients, based on their baseline levels of total cholesterol (TC) measured at admission, into 3 groups with <160, 160–200 and >200 mg/dL of TC. We evaluated risk of having initial stroke severity, with National Institutes of Health Stroke Scale (NIHSS) >15 and unfavorable outcomes (modified Rankin Scale [mRS] score >2, 3-month mortality) after ICH by the TC group. A total of 2444 ICH patients (mean age 62.5±14.2 years; 64.2% men) were included in this study and 854 (34.9%) of them had baseline TC <160 mg/dL. Patients with TC <160 mg/dL presented more often severe neurological deficit (NIHSS >15), with an adjusted odds ratio [aOR] of 1.80; 95% confidence interval [CI], 1.41–2.30), and 3-month mRS >2 (aOR, 1.41; 95% CI, 1.11–1.78) using patients with TC >200 mg/dL as reference. Those with TC >160 mg/dL and body mass index (BMI) <22 kg/m2 had higher risk of 3-month mortality (aOR 3.94, 95% CI 1.76–8.80). Prior use of lipid-lowering drugs (2.8% of the ICH population) was not associated with initial severity and 3-month outcomes. A total cholesterol level lower than 160 mg/dL was common in patients with acute ICH and was associated with greater neurological severity on presentation and poor 3-month outcomes, especially with lower BMI.

Abstract
Background Asians have higher frequency of intracranial arterial stenosis. The present study aimed to compare the clinical features and outcomes of ischemic stroke patients with and without middle cerebral artery (MCA) stenosis, assessed by transcranial sonography (TCS), based on the Taiwan Stroke Registry (TSR). Methods Patients with acute ischemic stroke or transient ischemic attack registered in the TSR, and received both carotid duplex and TCS assessment were categorized into those with stenosis (≥50%) and without (<50%) in the extracranial internal carotid artery (ICA) and MCA, respectively. Logistic regression analysis, Kaplan-Meier method and Cox proportional hazard model were applied to assess relevant variables between groups. Results Of 6003 patients, 23.3% had MCA stenosis, 10.1% ICA stenosis, and 3.9% both MCA and ICA stenosis. Patients with MCA stenosis had greater initial NIHSS, higher likelihood of stroke-in-evolution, and more severe disability than those without (all p<0.001). Patients with MCA stenosis had higher prevalence of hypertension, diabetes and hypercholesterolemia. Patients with combined MCA and extracranial ICA stenosis had even higher NIHSS, worse functional outcome, higher risk of stroke recurrence or death (hazard ratio, 2.204; 95% confidence intervals, 1.440–3.374; p<0.001) at 3 months after stroke than those without MCA stenosis. Conclusions In conclusion, MCA stenosis was more prevalent than extracranial ICA stenosis in ischemic stroke patients in Taiwan. Patients with MCA stenosis, especially combined extracranial ICA stenosis, had more severe neurological deficit and worse outcome.

Abstract
BACKGROUND We investigated the impact of serum cholesterol levels on 30-day mortality after ischemic stroke in dialysis patients. METHODS From the Taiwan Stroke Registry data, we identified 46,770 ischemic stroke cases, including 1101 dialysis patients and 45,669 nondialysis patients from 2006 to 2013. RESULTS Overall, the 30-day mortality was 1.46-fold greater in the dialysis group than in the nondialysis group (1.75 versus 1.20 per 1000 person-days). The mortality rates were 1.64, .62, 2.82, and 2.23 per 1000 person-days in dialysis patients with serum total cholesterol levels of <120 mg/dL, 120-159 mg/dL, 160-199 mg/dL, and ≥200 mg/dL, respectively. Compared to dialysis patients with serum total cholesterol levels of 120-159 mg/dL, the corresponding adjusted hazard ratios of mortality were 4.20 (95% confidence interval [CI] = 1.01-17.4), 8.06 (95% CI = 2.02-32.2), and 6.89 (95% CI = 1.59-29.8) for those with cholesterol levels of <120 mg/dL, 160-199 mg/dL, and ≥200 mg/dL, respectively. CONCLUSIONS Dialysis patients with serum total cholesterol levels of ≥160 mg/dL or <120 mg/dL on admission are at an elevated hazard of 30-day mortality after ischemic stroke.

Abstract
PURPOSE Reduced flow in the internal carotid artery (ICA) is related to cerebral ischemia. We established a classification of reduced ICA flow through color-coded carotid duplex (CCD) sonography. METHODS We retrospectively reviewed 25,000 CCD images in sonography laboratory. RESULTS Reduced ICA flow [flow volume (FV) less than 100 mL/min] was found in 1.2% of all studies, and 270 patients were enrolled. We included 8% patients with lesions proximal to the ICA in Group A, 27% with lesions at the proximal ICA in Group B, 49% with lesions distal to the visible ICA in Group C, and 16% with unknown causes in Group D. Distal ICA stenosis or occlusion is the most common cause of reduced ICA flow. Moyamoya disease, ICA hypoplasia, and ICA dissection were more prevalent in younger patients. CCD of the aforementioned diseases showed similar patterns of upstream high flow resistance with reduced FV in the ICA and were indistinguishable. The collateral flow from bilateral vertebral arteries increased in common carotid artery (CCA) or ICA disease (p less than 0.05) and was exceptionally high in ICA hypoplasia (p less than 0.001). Compared with the FV in the contralateral CCA, that of the ipsilateral CCA decreased in all groups (p less than 0.001), except in patients with low cardiac output. CONCLUSION CCD should be carefully performed and appropriately interpreted in reduced ICA flow. Additional magnetic resonance angiography is helpful in distinguishing stenosis or occlusion from ICA dissection and moyamoya disease, and skull base computed tomography is warranted for the confirmatory diagnosis of ICA hypoplasia. Key Words: color-coded carotid duplex sonography, dissection, hypoplasia, internal carotid artery, reduced flow, stenosis.

Abstract
Searches for a light sterile neutrino have been performed independently by the MINOS and the Daya Bay experiments using the muon (anti)neutrino and electron antineutrino disappearance channels, respectively. In this Letter, results from both experiments are combined with those from the Bugey-3 reactor neutrino experiment to constrain oscillations into light sterile neutrinos. The three experiments are sensitive to complementary regions of parameter space, enabling the combined analysis to probe regions allowed by the Liquid Scintillator Neutrino Detector (LSND) and MiniBooNE experiments in a minimally extended four-neutrino flavor framework. Stringent limits on sin^{2}2θ_{μe} are set over 6 orders of magnitude in the sterile mass-squared splitting Δm_{41}^{2}. The sterile-neutrino mixing phase space allowed by the LSND and MiniBooNE experiments is excluded for Δm_{41}^{2}<0.8 eV^{2} at 95% CL_{s}.

Abstract
This Letter reports an improved search for light sterile neutrino mixing in the electron antineutrino disappearance channel with the full configuration of the Daya Bay Reactor Neutrino Experiment. With an additional 404 days of data collected in eight antineutrino detectors, this search benefits from 3.6 times the statistics available to the previous publication, as well as from improvements in energy calibration and background reduction. A relative comparison of the rate and energy spectrum of reactor antineutrinos in the three experimental halls yields no evidence of sterile neutrino mixing in the 2×10^{-4}≲|Δm_{41}^{2}|≲0.3 eV^{2} mass range. The resulting limits on sin^{2}2θ_{14} are improved by approx imately a factor of 2 over previous results and constitute the most stringent constraints to date in the |Δm_{41}^{2}|≲0.2 eV^{2} region.

Abstract
PURPOSE Convexal subarachnoid hemorrhage (cSAH) comprises less than 5% of cases of nontraumatic SAH and frequently presents as a focal and transient neurological deficits that mimics transient ischemic attack (TIA). Isolated cortical vein thrombosis (ICVT) is rare and accounts for only 6.3% of cerebral venous thrombosis. We present a case of minor stroke due to cSAH secondary to ICVT, and alos put emphasis on the chronological change of those serial imagings. CASE REPORT An 87-year-old man presented with episodes of numbness and dropping of his left arm, which had lasted for three days. Brain computed tomography disclosed a cSAH in the right frontoparietal region. Brain magnetic resonance (MR) study showed a cSAH in the right fronto-parietal sulci. Focal swelling of the right frontal cortex with an intraluminal filling defect in the right cortical vein and venous congestion were observed using post-contrast T1-weighted images, suggesting partial thrombosis with recanalization of the cortical vein but a patent superior sagittal sinus. Diffuse linear superficial cortical hemosiderosis (SCH) was detected in the right anterior frontal cortex, right fronto-parietal cortex and left high frontal cortex. He spontaneously recovered from his minor neurological deficits within two weeks. A follow-up MR study three weeks later found a hyperintense cord sign indicating a cSAH in the right high central sulcus on fluid-attenuated inversion recovery and T2-weighted images. A further follow-up MR study two months later showed gradual shrinkage of the cSAH with persistent diffuse SCH. CONCLUSION This case report clearly showed chronological change of brain MRI and head CT findings. MR studies help in recognizing the occurrence of acute and chronic cSAHs, and ICVT.

Abstract
Background. Cardiac morbidities account for 20% of deaths after ischemic stroke and is the second commonest cause of death in acute stroke population. Elevation of cardiac troponin has been regarded as a prognostic biomarker of poor outcome in patients with acute stroke. Methods. This retrospective study enrolled 871 patients with acute ischemic stroke from August 2010 to March 2015. Data included vital signs, laboratory parameters collected in the emergency department, and clinical features during hospitalization. National Institutes of Health Stroke Scale (NIHSS), Barthel index, and modified Rankin Scale (mRS) were used to assess stroke severity and outcome. Results. Elevated troponin I (TnI) > 0.01 µg/L was observed in 146 (16.8%) patients. Comparing to patients with normal TnI, patients with elevated TnI were older (median age 77.6 years vs. 73.8 years), had higher median heart rates (80 bpm vs. 78 bpm), higher median white blood cells (8.40 vs. 7.50 1,000/m3) and creatinine levels (1.40 mg/dL vs. 1.10 mg/dL), lower median hemoglobin (13.0 g/dL vs. 13.7 g/dL) and hematocrit (39% vs. 40%) levels, higher median NIHSS scores on admission (11 vs. 4) and at discharge (8 vs. 3), higher median mRS scores (4 vs3) but lower Barthel index scores (20 vs. 75) at discharge (p < 0.001). Multivariate analysis revealed that age ≥ 76 years (OR 2.25, CI [1.59–3.18]), heart rate ≥ 82 bpm (OR 1.47, CI [1.05–2.05]), evidence of clinical deterioration (OR 9.45, CI [4.27–20.94]), NIHSS score ≥ 12 on admission (OR 19.52, CI [9.59–39.73]), and abnormal TnI (OR 1.98, CI [1.18–3.33]) were associated with poor outcome. Significant factors for in-hospital mortality included male gender (OR 3.69, CI [1.45–9.44]), evidence of clinical deterioration (OR 10.78, CI [4.59–25.33]), NIHSS score ≥ 12 on admission (OR 8.08, CI [3.04–21.48]), and elevated TnI level (OR 5.59, CI [2.36–13.27]). C-statistics revealed that abnormal TnI improved the predictive power of both poor outcome and in-hospital mortality. Addition of TnI > 0.01 ug/L or TnI > 0.1 ug/L to the model-fitting significantly improved c-statistics for in-hospital mortality from 0.887 to 0.926 (p = 0.019) and 0.927 (p = 0.028), respectively. Discussion. Elevation of TnI during acute stroke is a strong independent predictor for both poor outcome and in-hospital mortality. Careful investigation of possible concomitant cardiac disorders is warranted for patients with abnormal troponin levels.

Abstract
PURPOSE The immediate complications associated with a generalized tonic-clonic (GTC) seizure usually involve injuries such as aspiration pneumonia, head injury, skull or vertebral fracture and orolingual biting injury. Here we present a young man who suffered from GTC that was followed by a rare complication, acute diffuse pulmonary hemorrhage, which presented with massive hemoptysis and subsequent respiratory failure. CASE REPORT An 18-year-old boy developed a GTC convulsion that lasted for about two minutes and then regained consciousness 15 minutes later. Another GTC convulsion occurred four hours later for about two minutes. Upon admission, coughing with blood clots was noted and was initially imputed to a bite wound affecting the tongue. However, massive hemoptysis developed soon after. A chest X-ray showed diffuse consolidation of the bilateral lungs. He was transferred to the intensive care unit and was intubated immediately owing to acute respiratory failure. A further chest CT also showed extensive consolidation of the bilateral lungs, mainly in the central and posterior portions. Bronchoscopy showed diffuse tracheal and bronchial erythematous mucosa and post-hemorrhage changes. Laboratory surveys for autoimmune disease, infectious disease, tuberculosis and intoxication gave normal results. After treatment with anticonvulsants, antibiotics and corticosteroids, he was stabilized and extubated on the 5th day of hospitalization. CONCLUSION The disease entity of acute diffuse pulmonary hemorrhage is similar to neurogenic pulmonary edema. Physicians should be aware of this extremely rare but life-threatening complication, namely seizure-related acute diffuse pulmonary hemorrhage. The patient's response to respiratory support and corticosteroid is usually quite satisfactory.

Abstract
This Letter reports a measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near (effective baselines 512 and 561 m) and one far (1579 m) underground experimental halls in the Daya Bay experiment. Using 217 days of data, 296 721 and 41 589 inverse β decay (IBD) candidates were detected in the near and far halls, respectively. The measured IBD yield is (1.55±0.04) ×10(-18) cm(2) GW(-1) day(-1) or (5.92±0.14) ×10(-43) cm(2) fission(-1). This flux measurement is consistent with previous short-baseline reactor antineutrino experiments and is 0.946±0.022 (0.991±0.023) relative to the flux predicted with the Huber-Mueller (ILL-Vogel) fissile antineutrino model. The measured IBD positron energy spectrum deviates from both spectral predictions by more than 2σ over the full energy range with a local significance of up to ∼4σ between 4-6 MeV. A reactor antineutrino spectrum of IBD reactions is extracted from the measured positron energy spectrum for model-independent predictions.

Abstract
OBJECTIVES The prevalence of carotid disease in stroke patients has been underestimated because most stroke patients who receive carotid sonography have already survived the acute event. Little is known about the extracranial carotid arteries of patients with acute stroke who need intensive care. This study reviewed color-coded carotid duplex sonographic examinations of the extracranial carotid arteries of patients with acute critical hemispheric ischemic stroke. METHODS We retrospectively reviewed 30 consecutive patients who had acute critical hemispheric ischemic stroke and received color-coded carotid duplex sonography in the intensive care unit. The presence of occlusive carotid artery disease was correlated with clinical features, vascular risk factors, and outcomes. RESULTS Overall, 57% of the patients (17 of 30) had an occlusive internal carotid artery, and 44% of patients with atrial fibrillation (7 of 16) also had occlusive carotid disease. Eventually, 73% of the patients (21 of 30) had poor outcomes, and 57% (17 of 30) died. The contributing factors to a poor outcome were older age, an initial conscious disturbance, endotracheal intubation, and occlusive carotid disease, with the most significant factor being older age (P = .022; odds ratio, 27.76). The factors contributing to death were endotracheal intubation, occlusive carotid disease, and reversed ophthalmic flow, with the most significant factor being occlusive carotid disease (P = .014; odds ratio, 11.38). Soft homogeneously echogenic thrombi filling the lumen of the internal carotid artery and moving forward and backward with the carotid pulse were found in 3 patients. A small segment of ruptured plaque that was floating forward and backward with pulsation was found in 1 patient. CONCLUSIONS Occlusive carotid artery disease is not uncommon among Chinese patients who have had an acute critical hemispheric infarction. Older age is the factor most significantly correlated with a poor outcome, and occlusive carotid disease is the factor most significantly correlated with death.

Abstract
OBJECTIVES The purpose of this study was to determine the role of color-coded carotid duplex sonography for diagnosis of internal carotid artery hypoplasia. METHODS We retrospectively reviewed 25,000 color-coded carotid duplex sonograms in our neurosonographic database to establish more diagnostic criteria for internal carotid artery hypoplasia. RESULTS A definitive diagnosis of internal carotid artery hypoplasia was made in 9 patients. Diagnostic findings on color-coded carotid duplex imaging include a long segmental small-caliber lumen (52% diameter) with markedly decreased flow (13% flow volume) in the affected internal carotid artery relative to the contralateral side but without intraluminal lesions. Indirect findings included markedly increased total flow volume (an increase of 133%) in both vertebral arteries, antegrade ipsilateral ophthalmic arterial flow, and a reduced vessel diameter with increased flow resistance in the ipsilateral common carotid artery. Ten patients with distal internal carotid artery dissection showed a similar color-coded duplex pattern, but the reductions in the internal and common carotid artery diameters and increase in collateral flow from the vertebral artery were less prominent than those in hypoplasia. The ipsilateral ophthalmic arterial flow was retrograde in 40% of patients with distal internal carotid artery dissection. In addition, thin-section axial and sagittal computed tomograms of the skull base could show the small diameter of the carotid canal in internal carotid artery hypoplasia and help distinguish hypoplasia from distal internal carotid artery dissection. CONCLUSIONS Color-coded carotid duplex sonography provides important clues for establishing a diagnosis of internal carotid artery hypoplasia. A hypoplastic carotid canal can be shown by thin-section axial and sagittal skull base computed tomography to confirm the final diagnosis.

Abstract
We report a new measurement of electron antineutrino disappearance using the fully constructed Daya Bay Reactor Neutrino Experiment. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected from October 2012 to November 2013 resulted in a total exposure of 6.9×10^{5} GW_{th} ton days, a 3.6 times increase over our previous results. Improvements in energy calibration limited variations between detectors to 0.2%. Removal of six ^{241}Am-^{13}C radioactive calibration sources reduced the background by a factor of 2 for the detectors in the experimental hall furthest from the reactors. Direct prediction of the antineutrino signal in the far detectors based on the measurements in the near detectors explicitly minimized the dependence of the measurement on models of reactor antineutrino emission. The uncertainties in our estimates of sin^{2}2θ_{13} and |Δm_{ee}^{2}| were halved as a result of these improvements. An analysis of the relative antineutrino rates and energy spectra between detectors gave sin^{2}2θ_{13}=0.084±0.005 and |Δm_{ee}^{2}|=(2.42±0.11)×10^{-3} eV^{2} in the three-neutrino framework.

Abstract
A search for light sterile neutrino mixing was performed with the first 217 days of data from the Daya Bay Reactor Antineutrino Experiment. The experiment's unique configuration of multiple baselines from six 2.9 GW(th) nuclear reactors to six antineutrino detectors deployed in two near (effective baselines 512 m and 561 m) and one far (1579 m) underground experimental halls makes it possible to test for oscillations to a fourth (sterile) neutrino in the 10(-3) eV(2)<|Δm(41)(2) |< 0.3 eV(2) range. The relative spectral distortion due to the disappearance of electron antineutrinos was found to be consistent with that of the three-flavor oscillation model. The derived limits on sin(2) 2θ(14) cover the 10(-3) eV(2) ≲ |Δm(41)(2)| ≲ 0.1 eV(2) region, which was largely unexplored.

Abstract
PURPOSE Carotid blowout syndrome due to rupture of internal carotid artery pseudoaneurysm in NPC patients with prior neck radiation is an uncommon but life-threatening complication. Concomitant carotid stenosis with ischemic stroke and carotid rupture from pseudoaneurysm is rare. CASE REPORT A 71-year-old man had a history of NPC treated with radiation therapy 26 years ago. He was admitted to the hospital because of minor ischemic stroke and tarry stool. The carotid duplex sonography disclosed severe stenotic lesion in the proximal right internal carotid artery. A subsequent recurrent stroke on day three associated with nasal cavity bleeding resulted in an endotracheal intubation. Another episodic of massive epistaxis occurred on day 10 caused hypovolemic shock. Pseudoaneurysm of the left internal carotid artery was found by emergent angiography and was immediately obliterated by endovascular treatment with microcoils and glue. CONCLUSION Carotid blowout syndrome in NPC patients during acute ischemic stroke warrants further cervical angiographic study. Endovascular treatment provides immediate hemostasis and obliteration of ICA pseudoaneurysm.

Abstract
We report here the technology and the underlying science of a new device for inhalation (pulmonary) drug delivery which is capable of fulfilling needs unmet by current commercial devices. The core of the new device is a centimeter-size clog-free silicon-based ultrasonic nozzle with multiple Fourier horns in resonance at megahertz (MHz) frequency. The dramatic resonance effect among the multiple horns and high growth rate of the MHz Faraday waves excited on a medicinal liquid layer together facilitate ejection of monodisperse droplets of desirable size range (2-5 µm) at low electrical drive power (<1.0 W). The small nozzle requiring low drive power has enabled realization of a pocket-size (8.6 × 5.6 × 1.5 cm3) ultrasonic nebulizer. A variety of common pulmonary drugs have been nebulized using the pocket-size unit with desirable aerosol sizes and output rate. These results clearly provide proof-of-principle for the new device and confirm its potential for commercialization.
