Abstract
INTRODUCTION Mixing tests in activated partial thromboplastin time (APTT) are used for the differentiation between lupus anticoagulants (LA), coagulation inhibitors, and factor deficient samples with APTT prolongation. However, the indexes for the differentiation have not been established. The present study aimed to develop new mixing test indexes for the differentiation. METHODS Twenty-six LA-positive, 8 progressive coagulation factor VIII inhibitor, and 35 coagulation deficient samples were employed. APTT were measured for normal plasma, patient plasma, and mixing plasma prepared at a ratio of 1:1 proportion in both without incubation and 2 h-incubation. New two parameters named as ALD50 and mixture plasma-patient plasma after Warming change rate Subtraction (WaS) calculated from the clotting times of normal, 1:1 mixing and patient samples with/without 2 h-incubation were established. In the samples with WaS result of <10.2%, ALD50 of ≥87.8%, and < 87.8% were defined as LA and coagulation factor deficiency, respectively, and WaS of ≥10.2% defined progressive coagulation factor inhibitors. RESULTS Sensitivity and specificity to LA were 80.8% and 93.0% for ALD50, and sensitivity and specificity to progressive coagulation factor inhibitor were 100.0% and 100.0% for WaS, respectively. The agreement between sample classification and WaS-ALD50 was 88.4% (61/69). CONCLUSIONS ALD50 and WaS showed acceptable sensitivity and specificity to LA and progressive coagulation factor inhibitor, respectively. These indexes would be useful for the differentiation between LA, factor deficiency, and progressive coagulation factor inhibitor in the mixing tests.

Abstract
OBJECTIVE To investigate the potential of whole-body digital 11C-methionine (MET) PET/CT imaging for simultaneous evaluation of thoracic cancer patients suspected of local recurrence (LR) after stereotactic radiosurgery (SRS) for brain metastasis. METHODS A total of 45 lung or breast cancer patients suspected of LR after SRS were investigated using brain and whole-body MET-PET/CT scans. We compared the tumor-to-normal ratio (TNR) and maximum standardized uptake values (SUVmax) between patients with LR and radiation necrosis (RN) and performed receiver operating characteristic (ROC) analyses. We also investigated associations among extracranial recurrence, intracranial recurrence, primary site, and initial treatment type. RESULTS A total of 44 LR and 14 RN lesions were analyzed. In the ROC analyses for differentiating LR from RN, TNR showed higher area under the curve (AUC) (0.82) than SUVmax (0.79), and the cutoff TNR value (2.12) was higher than current cutoff values of conventional PET systems. The whole-body scans detected extracranial recurrences in 31.1% of the patients. Recurrence rates were not significantly correlated with existence of intracranial recurrence or primary site, but patients who underwent non-surgical treatment (consisting of stage III/ IV patients according to the Union for International Cancer Control TNM classification or small-cell lung cancer patients) showed significantly higher recurrence than the surgically treated patients (68.8% vs. 10.3%, p = 0.0001). CONCLUSION In digital MET-PET/CT imaging, TNR was a more useful parameter to differentiate LR from RN than SUVmax, and the cutoff value was higher than those with conventional PET systems. Additional whole-body scans could detect extracranial recurrence and would be especially useful for advanced thoracic cancer patients who underwent non-surgical treatment.

Abstract
PURPOSE To investigate the 5-year treatment outcomes of retinopathy of prematurity in infants <500 g birth weight and compare laser and anti-vascular endothelial growth factor therapies. METHODS A multicenter retrospective study comprised 24 eyes of 13 patients treated for Type 1 retinopathy of prematurity, followed for 5 years. Initial treatment was laser and anti-vascular endothelial growth factor in 13 and 11 eyes, respectively. Data collected included sex, birth characteristics, retinopathy of prematurity characteristics at the time of treatment, best-corrected visual acuity (BCVA), spherical equivalent, and astigmatism at 5 years posttreatment. RESULTS Median BCVA was 0.15 logarithm of the minimum angle of resolution (interquartile range, 0.0-0.5). Snellen BCVA was ≥20/40 in 73% and ≥20/20 in 27% of eyes. Median spherical equivalent was -2.37 (interquartile range, -6.1 to -0.1); 75% had myopia (≤-0.5 D), and 25% had high myopia (≤-6.0 D). Median astigmatism was 1.25 (interquartile range, 0.9-3.0); 46% had ≥1.5 D. Anti-vascular endothelial growth factor-treated eyes showed less myopia ( P < 0.009), with no BCVA or astigmatism difference ( P = 0.997, P = 0.271) compared with laser-treated eyes. CONCLUSION One-quarter of the eyes exhibited good visual acuity (Snellen BCVA of ≥20/20) 5 years after retinopathy of prematurity treatment. Refractive errors were common. Anti-vascular endothelial growth factor therapy may be superior to laser therapy in myopic refractive error.

Abstract
PURPOSE The impact of various preoperative glaucoma medications on Schlemm's canal surgery outcomes remains unclear. This study aimed to investigate the impact of preoperative glaucoma medications on the postoperative 1-year outcomes of μTLO. METHODS We analyzed the medical records of 218 patients who underwent their first μTLO to investigate the 1-year postoperative outcomes. Cox proportional hazard regression analysis was performed with surgical failure as the dependent variable and each type of preoperative medication as the independent variable. We also compared the 1-year outcomes of μTLO between users and non-users of specific medications using propensity score matching. Surgical success was defined as a postoperative intraocular pressure ranging from 5 to 21 mmHg, a ≥20% reduction in IOP from baseline, and no additional glaucoma surgery within 1 year postoperatively. RESULTS The Cox proportional hazard analysis showed that all drugs that do not increase the conventional outflow exhibited hazard ratios greater than 1.0, and the preoperative use of β-blockers and oral CAI was a significant surgical risk factor (hazard ratio: 2.65 and 2.45, p = 0.04 and <0.001). In the propensity score matching analysis, success rates at 1 year postoperatively were 55/85, 54/79, 60/73, and 40/76% for users/non-users of β-blockers, topical CAIs, an alpha-2 adrenergic agonist, and an oral CAI, respectively. Kaplan-Meier survival curves in these comparisons also demonstrated that preoperative β-blockers and oral CAI use were significant surgical risks (p = 0.01, <0.001). CONCLUSION Our study suggests that preoperative medications that do not involve conventional pathway outflow have a detrimental effect on subsequent Schlemm's canal surgery outcomes.

Abstract
The recent implementation of attosecond and few-femtosecond X-ray pump/X-ray probe schemes in large-scale free-electron laser facilities has opened the way to visualize fast nuclear dynamics in molecules with unprecedented temporal and spatial resolution. Here, we present the results of theoretical calculations showing how polarization-averaged molecular-frame photoelectron angular distributions (PA-MFPADs) can be used to visualize the dynamics of hydrogen migration in methanol, ethanol, propanol, and isopropyl alcohol dications generated by X-ray irradiation of the corresponding neutral species. We show that changes in the PA-MFPADs with the pump-probe delay as a result of intramolecular photoelectron diffraction carry information on the dynamics of hydrogen migration in real space. Although visualization of this dynamics is more straightforward in the smaller systems, methanol and ethanol, one can still recognize the signature of that motion in propanol and isopropyl alcohol and assign a tentative path to it. A possible pathway for a corresponding experiment requires an angularly resolved detection of photoelectrons in coincidence with molecular fragment ions used to define a molecular frame of reference. Such studies have become, in principle, possible since the first XFELs with sufficiently high repetition rates have emerged. To further support our findings, we provide experimental evidence of H migration in ethanol-OD from ion-ion coincidence measurements performed with synchrotron radiation.

Abstract
To investigate the association between lactate metabolism and glaucoma, we conducted a multi-institutional cross-sectional clinical study and a retinal metabolomic analysis of mice with elevated intraocular pressure (IOP) induced by intracameral microbead injection. We compared lactate concentrations in serum and aqueous humor in age-matched 64 patients each with primary open-angle glaucoma (POAG) and cataract. Neither serum nor aqueous humor lactate concentrations differed between the two groups. Multiple regression analysis revealed that only body mass index showed a significant positive correlation with serum and aqueous humor lactate concentration in POAG patients (rs = 0.376, P = 0.002, and rs = 0.333, P = 0.007, respectively), but not in cataract patients. L-Lactic acid was one of the most abundantly detected metabolites in mouse retinas with gas chromatography and mass spectrometry, but there were no significant differences among control, 2-week, and 4-week IOP elevation groups. After 4 weeks of elevated IOP, D-glucose and L-glutamic acid ranked as the top two for a change in raised concentration, roughly sevenfold and threefold, respectively (ANOVA, P = 0.004; Tukey-Kramer, P < 0.05). Glaucoma may disrupt the systemic and intraocular lactate metabolic homeostasis, with a compensatory rise in glucose and glutamate in the retina.

Abstract
OBJECTIVES To investigate factors influencing postoperative bleeding occurrence after dental extraction in older patients receiving anticoagulation therapy. MATERIALS AND METHODS This retrospective study included patients aged ≥ 65 years receiving one of the following anticoagulants: apixaban, edoxaban, rivaroxaban, and warfarin. Patients who underwent one to multiple tooth extractions in the geriatric dentistry clinic at Tokyo Medical and Dental University Hospital between August 1, 2016, and November 30, 2020, were included. The outcome variable was postoperative bleeding occurrence. Logistic regression analysis was performed with the following ten factors as explanatory variables: age, sex, maximum systolic blood pressure during the extraction, type of local anesthesia, vertical incision, osteotomy, usage of surgical splints, the mesiodistal width of the extracted tooth on a radiograph, use of antiplatelet agents, and history of diabetes requiring medication. RESULTS Among 395 participants (mean age, 82.3 ± 6.5 years) included in this study, 75 patients experienced postoperative bleeding after tooth extraction. Logistic regression analysis revealed that the odds ratios for the vertical incision (18.400, p < 0.001), osteotomy (3.630, p = 0.00558), usage of surgical splints (1.860, p = 0.0395), and the mesiodistal width of the extracted tooth on a radiograph (1.060, p = 0.0261) were statistically significant. CONCLUSIONS For dental extraction in older patients receiving anticoagulants, postoperative bleeding is more likely to occur in patients with vertical incision, osteotomy, and posterior or multiple tooth extractions. CLINICAL RELEVANCE Dentists should consider suturing and adjunctive hemostatic procedures for patients undergoing vertical incision, osteotomy, and multiple tooth extractions while receiving anticoagulation therapy to minimize the risk of postoperative bleeding.

Abstract
INTRODUCTION Leber hereditary optic neuropathy (LHON) is a maternally inherited, acute or subacute, optic neuropathy. The typical symptoms include reduced visual acuity and central scotoma. Despite the presence of deep central scotoma, some patients with LHON are able to perform daily activities. This study aimed to investigate the correlation between the residual visual field and visual acuity, critical flicker frequency, and fixation ellipse in patients with chronic LHON. METHODS Residual visual function (defined as sensitivity points where patients sensed the size V stimulus) of both eyes was evaluated in 10 patients with LHON carrying the m.11778 mitochondrial DNA mutation and with median age of onset and disease duration of 29 and 16.5 years, respectively. The central visual field was measured as static perimetry using the Humphrey visual field testing 30-2 program with the size III or V stimulus. Moreover, best-corrected visual acuity, critical flicker frequency, and the correlation between fixation ellipse and residual central visual fields were determined. The analysis was performed through a linear mixed-effects model. RESULTS The residual visual sensitivity in the inferior nasal visual field was significantly correlated with the logMAR (p < 0.05). The fixation ellipse fell within the residual visual field region with higher sensitivity. CONCLUSIONS Patients with chronic LHON tended to retain the sensitivity detectable with the size V stimulus at the central inferior nasal visual field regions, where the fixation ellipse fell. Visual acuity, which influences daily activity, was spatially correlated with residual visual sensitivity.

Abstract
OBJECTIVES To compare real-world, long-term outcomes of laser and anti-vascular endothelial growth factor (VEGF) therapies in patients with retinopathy of prematurity (ROP). METHODS This was a multicentre retrospective study. We included 264 eyes of 139 patients treated for type 1 ROP or aggressive ROP (AROP) who were followed for at least 4 years. Laser treatment was initially performed in 187 eyes (the laser group), and anti-VEGF therapy was initially performed in 77 eyes (the anti-VEGF group). We collected data on sex, birth characteristics, zone, stage, and the presence of plus disease at the time of treatment and best-corrected visual acuity (BCVA), spherical equivalent (SE), and ocular complications (amblyopia and strabismus) in patients aged 4-6 years. We investigated the associations between treatment outcomes (BCVA, SE and the presence of amblyopia and strabismus) and influencing factors, including treatment procedure (anti-VEGF or laser therapy), sex, birth characteristics, zone, stage, and the presence of plus disease, using multivariable analysis and logistic regression analyses. RESULTS The initial treatment procedure was not associated with any specific treatment outcome. Subgroup analysis of patients with zone I ROP revealed that the anti-VEGF-treated eyes had significantly better BCVA and higher SE than laser-treated eyes (p = 0.004, p = 0.009, respectively). Female patients presented significantly better BCVA, less amblyopia and less strabismus than male patients (p < 0.001, p = 0.029, p = 0.008, respectively). CONCLUSIONS In zone I ROP, anti-VEGF therapy led to better visual acuity and less myopic refractive error than laser treatment.

Abstract
Approximately 60% of adenoid cystic carcinoma (AdCC) cases are positive for MYB::NFIB or MYBL1::NFIB, whereas MYB/MYBL1 oncoprotein, a key driver of AdCC, is overexpressed in most cases. Juxtaposition of superenhancer regions in NFIB and other genes into the MYB/MYBL1 locus is an attractive oncogenic hypothesis for AdCC cases, either negative or positive for MYB/MYBL1::NFIB. However, evidence supporting this hypothesis is insufficient. We examined 160 salivary AdCC cases for rearrangements in MYB/MYBL1 loci and peri-MYB/MYBL1 areas (centromeric and telomeric areas of 10 Mb each) using formalin-fixed, paraffin-embedded tumor sections. For the detection of the rearrangements, we employed conventional fluorescence in situ hybridization split and fusion assays and a 5 Mb fluorescence in situ hybridization split assay. The latter is a novel assay that enabled us to detect any possible splits within a 5 Mb distance of a chromosome. We found MYB/MYBL1- and peri-MYB/MYBL1-associated rearrangements in 149/160 patients (93%). AdCC cases positive for rearrangements in MYB, MYBL1, the peri-MYB area, and the peri-MYBL1 area numbered 105 (66%), 20 (13%), 19 (12%), and 5 (3%), respectively. In 24 peri-MYB/MYBL1 rearrangement-positive cases, 14 (58%) were found to have a juxtaposition of the NFIB or RAD51B locus into the MYB/MYBL1 loci. On comparing with a tumor group positive for MYB::NFIB, a hallmark of AdCC, other genetically classified tumor groups had similar features of overexpression of the MYB transcript and MYB oncoprotein as detected by semiquantitative RT-qPCR and immunohistochemistry, respectively. In addition, clinicopathological and prognostic features were similar among these groups. Our study suggests that peri-MYB/MYBL1 rearrangements may be a frequent event in AdCC and may result in biological and clinicopathological consequences comparable to MYB/MYBL1 rearrangements. The landscape of MYB/MYBL1 and peri-MYB/MYBL1 rearrangements shown here strongly suggests that juxtaposition of superenhancers into MYB/MYBL1 or peri-MYB/MYBL1 loci is an alteration that acts as a key driver for AdCC oncogenesis and may unify MYB/MYBL1 rearrangement-positive and negative cases.

Abstract
PURPOSE/OBJECTIVE(S) For stage IV non-small cell lung cancer (NSCLC), the treatment drug is selected based on the gene mutation status. However, the dose or field of radiation therapy is not change based on the genetic status. We evaluated both clinical and in vitro data, showing that the presence or absence of epidermal growth factor receptor (EGFR) mutations affects radiosensitivity in patients with brain metastases (BM) from NSCLC. MATERIALS/METHODS Patients with BM from NSCLC who received whole brain radiotherapy (WBRT) were enrolled in this study. Patient characteristics are shown in the Table. EGFR mutations were observed in 13 (31.0%) patients. The prescribed dose was 30 Gy in 10 fractions (85.7%). The A549, VMRC-LCD, NCI-H1975, and HCC4006 cell lines were used for the in vitro study. EGFR mutation was negative in A549 and VMRC-LCD and positive in NCI-H1975 (exon21) and HCC4006 (exon19). After irradiation of these cell lines with 0, 2, 4, and 8 Gy, a colony formation assay was performed. DNA double-strand breaks (DSBs) were assessed 30 min and 24 h after 4 Gy irradiation using γH2AX. RESULTS The median follow-up period was 4 months (range, 1-35). Intracranial recurrence was observed in 14 (33.3%) patients during the follow-up period. Thirty-nine (92.9%) patients died during the follow-up period. Patients with EGFR mutation-positive tumors had significantly better intracranial control rates than those with EGFR mutation-negative tumors (p = 0.0213). A similar tendency was observed in the analysis conducted, except for the cases in which tyrosine kinase inhibitor (TKI) was administered after WBRT. In the EGFR mutation-positive group, no significant difference was observed between patients who received TKI after WBRT and those who did not (p = 0.527). In the colony formation assay, EGFR mutation-positive cell lines showed a significantly lower number of colonies formed after irradiation with 2 and 4 Gy than mutation-negative cell lines (p = 0.00018 and 0.0000291, respectively). EGFR mutation-positive cell lines had significantly more DNA-DSBs remaining 24 h after irradiation than mutation-negative cell lines (p = 0.0000000312). CONCLUSION Our data suggest that patients with EGFR mutation-positive NSCLC are more radiosensitive than those with negative EGFR mutations.

Abstract
PURPOSE/OBJECTIVE(S) There are several methods used against respiratory motion (RM). Expiratory breath-hold (BH) is considered more stable and reproducible than inspiratory BH; therefore, BH with spirometry is often used for expiration. The real-time tumor tracking radiotherapy (RTRT) system is a highly effective method for reducing the margin of RM. This system ambushes and irradiates tumors during the expiratory phase when tumors move slowly. Although these methods usually involve expiration, it is advantageous to expand the lungs with inspiration to reduce the risk of adverse events. Here, we developed a new approach of performing stereotactic body radiation therapy (SBRT) under deep-inspiration BH (DIBH) by combining these two methods. MATERIALS/METHODS Lung tumors with respiratory motion ≥ 1 cm were included. Three or four fiducial markers were placed near the tumor via bronchoscopy. DIBH CT (CT-IN) was performed under the guidance of spirometer. The PTV was obtained by adding a 5-mm margin to the GTV delineated on CT-IN. The prescribed dose was 42 Gy in four fractions for the D95 of the PTV. An error of 2.0 mm around the planned position of the fiducial marker on CT-IN was permitted along each orthogonal axis as a gating box. In preparation for cases in which the reproducibility of DIBH is low and treatment cannot be performed, light expiration BH CT (CT-EX) was also performed, and a radiotherapy plan was prepared for the conventional RTRT system so that it could be switched at any time. Lung volumes and doses (mean dose, V20 Gy, V10 Gy, and V5 Gy) on CT-EX and CT-IN were compared. RESULTS Five patients underwent SBRT with DIBH, and all completed the planned irradiation course. The median treatment time per fraction was 27.86 min (range, 25.5-40.6). Four tumors were located in the left lower lobe and one in the right lower lobe. The median volume of PTV was 12.4 (range, 5.2-26.2) mL. The lung volumes and doses on CT-EX and CT-IN are shown in the Table. The lung volume on CT-IN was 1.6 times larger than that on CT-EX. The PTV-to-lung ratio on CT-IN was significantly lower than that on CT-EX. V20 Gy and V10 Gy on CT-IN were significantly lower than those on CT-EX. CONCLUSION SBRT with DIBH was achieved by combining the spirometer and RTRT system. This can help to eliminate concerns about reproducibility and high-speed tumor movement during inspiration, which are weaknesses of spirometer-guided breath-hold and the RTRT system, respectively, while ensuring the accuracy of the RTRT system. DIBH SBRT is a promising method that can reduce lung dose.

Abstract
PURPOSE To evaluate the reproducibility of the imo binocular random single-eye test (BRSET) and Humphrey Field Analyzer (HFA) monocular test in patients with glaucoma. STUDY DESIGN Retrospective observational study. METHODS We measured the visual fields (VF) of patients with glaucoma using the BRSET and HFA. All tests were repeated two months later. Mean sensitivity (MS), mean deviation (MD), sensitivity at each test location, and reliability indices were compared between the test days. Wilcoxon signed-rank test, interclass correlation coefficient (ICC), correlation coefficients, and Bland-Altman plots were generated for analysis. RESULTS We analyzed the VFs of 46 patients with glaucoma. There were no test-retest differences for MS and MD, and ICCs were > 0.9 for MS and MD in both perimeters. Inter-test correlations for MS and MD were high. The limits of agreement (LoAs) (lower, upper limit) between test days for MS were (- 3.4, 4.0) for BRSET and (-3.3, 3.0) for HFA. The LoA for MD was (- 3.3, 3.8) for BRSET and (- 3.2, 2.9) for HFA. Sensitivity at each testing location was more variable between testing days for BRSET than for HFA. For reliability indices, LoAs between testing days were wider for BRSET than for HFA. CONCLUSION The imo BRSET showed similar reproducibility to HFA in MS and MD. However, sensitivity at each test location varied more for BRSET than for HFA. Further studies are needed to verify the reproducibility of the imo BRSET.

Abstract
INTRODUCTION This multicenter, randomized, comparative, and investigator-masked crossover clinical trial sought to compare the efficacy and tolerability of fixed combinations of 0.1% brimonidine/0.5% timolol (BTFC) versus 1% dorzolamide/0.5% timolol (DTFC) as adjunctive therapies to prostaglandin analogues. METHODS A total of 110 patients with open-angle glaucoma or ocular hypertension previously treated with prostaglandin analogue monotherapy were randomized to receive either BTFC or DTFC as adjunctive therapy for 8 weeks. These patients were then crossed over to the alternative treatment arm for another 8 weeks. The reduction in intraocular pressure (IOP) (primary outcome), occurrence of adverse events, ocular discomfort after instillation, and patient preference (secondary outcomes) were recorded through patient interviews. RESULTS BTFC instillation for 8 weeks reduced IOP by 3.55 mmHg, demonstrating non-inferiority to DTFC instillation (3.60 mmHg; P < 0.0001, mixed-effects model). Although adverse events were rare with both combinations, patients reported greater discomfort with DTFC than with BTFC (P < 0.0001). More patients preferred BTFC (P < 0.0001) over DTFC, as BTFC caused minimal or no eye irritation. CONCLUSION As BTFC offered better tolerability than DTFC with comparable reduction in IOP, we recommend it as an alternative for patients who experience ocular discomfort with DTFC-prostaglandin analogue combination therapy.

Abstract
PURPOSE We have previously demonstrated that prolonged use of glaucoma medications was associated with a poor surgical outcome of ab interno trabeculotomy (µTLO). Given that almost all types of glaucoma eye drop either enhance the drainage through the uveoscleral pathway or reduce aqueous humor production, we hypothesized that prolonged use of these medications might cause disuse atrophy of the conventional pathway. In contrast, ripasudil increases the conventional outflow and eventually shows a favorable outcome of µTLO. This study aimed to evaluate the effect of ripasudil use on µTLO outcomes. METHOD The medical charts of 218 patients who underwent µTLO were analyzed retrospectively. We compared the 1-year outcome between ripasudil users versus nonusers by using propensity score matching. We set the covariates as age, sex, glaucoma types, preoperative intraocular pressure (IOP), the mean deviation values of visual field tests, the presence or absence of concomitant cataract surgery, trabecular meshwork incision range, the presence or absence of any glaucoma medication except ripasudil and duration of glaucoma medical therapy. Success was defined as a postoperative IOP between 5 and 21 mmHg, a ≥ 20% IOP reduction from baseline, and no additional glaucoma surgery at postoperative 1 year. RESULT Fifty-seven patients each were allocated to the ripasudil users or nonusers. The 1-year success rates were 74% in ripasudil users and 51% in nonusers (p = 0.01). Kaplan‒Meier survival curves also showed that the ripasudil users had a higher survival distribution (p = 0.01). CONCLUSION The patients who took ripasudil showed a favorable 1-year outcome of µTLO.

Abstract
Patients with asymmetric glaucomatous optic neuropathy (GON) present a relative afferent pupillary defect (RAPD) in the eye with more advanced damage. Although useful, pupillometric RAPD quantification is not widely used as it is not portable. Whether asymmetry of the peripapillary capillary perfusion density (CPD) detected using optical coherence tomography angiography correlates with the severity of RAPD remains unknown. This study assessed RAPD in 81 patients with GON using Hitomiru, a novel hand-held infrared binocular pupillometer. The correlation and ability to detect clinical RAPD based on the swinging flash light test of two independent RAPD parameters (the maximum pupil constriction ratio and the constriction maintenance capacity ratio) were assessed. The coefficient of determination (R2) was calculated between each of the two RAPD parameters and asymmetry of the circumpapillary retinal nerve fiber layer thickness (cpRNFLT), ganglion cell layer/inner plexiform layer thickness (GCL/IPLT), and CPD. The two RAPD parameters showed a correlation coefficient of 0.86 and areas under the receiver operating characteristic (ROC) curve of 0.85-0.88, with R2 being 0.63-0.67 for the visual field, 0.35-0.45 for cpRNFLT, 0.45-0.49 for GCL/IPLT, and 0.53-0.59 for CPD asymmetry. Hitomiru has high discriminatory performance in detecting RAPD in patients with asymmetric GON. CPD asymmetry may better correlate with RAPD than cpRNFLT and GCL/IPLT asymmetry.

Abstract
We present a study on molecular-frame photoelectron angular distributions (MFPADs) of small molecules using circularly polarized synchrotron light. We find that the main forward-scattering peaks of the MFPADs are slightly tilted with respect to the molecular axis. This tilt angle is directly connected to the molecular bond length by a simple, universal formula. We apply the derived formula to several examples of MFPADs of C 1s and O 1s photoelectrons of CO, which have been measured experimentally or obtained by means of ab initio modeling. In addition, we discuss the influence of the back-scattering contribution that is superimposed over the analyzed forward-scattering peak in the case of homo-nuclear diatomic molecules such as N2.

Abstract
An open-loop control scheme of molecular fragmentation based on transient molecular alignment combined with single-photon ionization induced by a short-wavelength free electron laser (FEL) is demonstrated for the acetylene cation. Photoelectron spectra are recorded, complementing the ion yield measurements, to demonstrate that such control is the consequence of changes in the electronic response with molecular orientation relative to the ionizing field. We show that stable C2H2+ cations are mainly produced when the molecules are parallel or nearly parallel to the FEL polarization, while the hydrogen fragmentation channel (C2H2+ → C2H+ + H) predominates when the molecule is perpendicular to that direction, thus allowing one to distinguish between the two photochemical processes. The experimental findings are supported by state-of-the art theoretical calculations.

In this case report, we introduce a fully digital workflow for surgical splint fabrication to prevent postoperative bleeding in patients receiving anticoagulants and/or at risk of inadvertent extraction of a mobile tooth during impression making. An 87-year-old woman using apixaban had a left mandibular canine that required extraction due to chronic apical periodontitis. A digital impression was obtained using an intraoral scanner. First, the tooth to be extracted was deleted using three-dimensional (3D) computer-aided design (CAD) software (Geomagic Freeform, 3D Systems) and a stereolithography (STL) file was exported. This modified STL file was imported into another CAD software (3Shape Dental System, 3Shape) and a surgical splint was designed. The splint was fabricated using a 3D printer (Form 3; Formlabs) and light-curable resin (Dental LT Clear, Formlabs) and was delivered after the tooth extraction. The patient was followed-up 2 days after the extraction; no postoperative bleeding was detected and the surgical splint was removed. The additively manufactured surgical splint fabricated using a fully digital workflow was efficacious for managing postoperative bleeding after a dental extraction.

Abstract
Background Leber hereditary optic neuropathy (LHON) is an acute or subacute optic neuropathy that mainly affects young males. The first nationwide epidemiological survey of LHON was conducted in 2014 in Japan, and LHON was officially designated as a rare intractable disease by the Japanese government in 2015. We conducted a second survey of the annual incidence of LHON in 2019, and estimated the total number of patients with LHON in Japan. Results A questionnaire was sent to 997 facilities accredited by the Japanese Ophthalmological Society and/or affiliated with the councilors of the Japanese Neuro-Ophthalmology Society. Responses were received from 791 facilities, with a response rate of 79%. Fifty-five newly diagnosed cases (49 males and 6 females) of LHON were reported from 35 institutions in 2019, with a median age of 28.5 for males and 49.5 years for females. The total number of newly diagnosed cases was calculated as 69 (62 were males and 7 were females, 95% confidence interval 55–83), and the total number of patients was estimated to be 2491 (95% confidence interval: 1996–2986), suggesting a prevalence of LHON in Japan of 1:50,000. Conclusion The incidence of LHON in 2019 was lower than the estimate in 2014, whereas its prevalence may be similar to that reported in other countries. The accurate estimation of the incidence and prevalence of patients with LHON requires prospective registration.

Abstract
PURPOSE The purpose of this retrospective study was to determine the extent to which the use of antithrombotic drugs during glaucoma surgery contributes to surgical failure and postsurgical hemorrhagic complications. METHODS Glaucoma surgeries were categorized into three groups: trabeculotomy (TLO), trabeculectomy (TLE), and long-Tube shunt surgery (Tube). At 1 year after surgery, the following criteria for surgical success were met: intraocular pressure (IOP) in the 5-21-mmHg range, IOP reduction of at least 20% from the preoperative level, and no additional glaucoma surgeries. We compared the percentages of the success rates and hemorrhagic complications between antithrombotic medication experiencers and non-experiencers. Furthermore, we adjusted the preoperative factors between the two groups using a propensity score analysis in TLO and TLE surgeries. RESULTS A total of 910 glaucoma surgeries were included, with TLO, TLE, and Tube accounting for 353, 444, and 113 surgeries, respectively. Preoperative antithrombotic medications were administered to 149 patients in all glaucoma surgeries: 37 patients used only anticoagulants, 102 used only antiplatelets, and 10 used both. There was no significant difference in the success rates of any of the procedures. The hemorrhagic complications (hyphema and vitreous hemorrhage rate) were significantly higher in the patients who underwent TLE and Tube. The surgical success rates of TLO and TLE were not significantly different after the two groups were matched by propensity score. CONCLUSION The perioperative use of antithrombotic drugs did not affect success for any of the procedures. However, it increased early postoperative hemorrhagic complications for TLE and Tube.

Abstract
Background Salivary duct carcinoma (SDC) is a high‐grade salivary malignancy that frequently occurs as the carcinomatous component of carcinoma ex pleomorphic adenoma. We herein examined the clinical factors affecting outcomes in a large cohort of SDC. Methods We selected 304 SDC cases and investigated clinical characteristics and the factors affecting outcomes. Results The median age of the cases examined was 68 years, the most common primary site was the parotid gland (238 cases), and there was a male predominance (M/F = 5:1). Outcomes were significantly worse when the primary tumor site was the minor salivary glands (SG) than when it was the major SG. Outcomes were also significantly worse in pN(+) cases (161 cases) than in pN0 cases, particularly those with a metastatic lymph node number ≥11. The cumulative incidence of relapse and distant metastases was significantly higher in stage IV cases than in stage 0–III cases. Conclusions The absolute number of lymph node metastases, higher stages, and the minor SG as the primary tumor site were identified as factors affecting the outcome of SDC.

Abstract
PURPOSE This study examined the perioperative factors affecting surgical success in ab interno microhook trabeculotomy (μTLO). METHODS A total of 146 consecutive patients who underwent μTLO were included in this retrospective study. We performed Cox proportional hazard modelling by setting surgical success at 1 year as an objective variable. The explanatory variables included age, sex, glaucoma type, preoperative intraocular pressure (IOP), glaucoma drug score, mean deviation (MD) of the Humphrey visual field test, duration of glaucoma drug use, antithrombotic drug use, combined cataract surgery, incision range and diabetes mellitus. Additionally, we performed 1:1 matching using propensity score analysis and compared the perioperative parameters between durations of glaucoma drug use of <4.5 years and ≥ 4.5 years (50 patients each). We defined surgical success as satisfaction of all three criteria: IOP 5-21 mmHg, IOP reduction of ≥20% from the preoperative IOP and no additional glaucoma surgery. RESULTS The Cox proportional hazard model revealed that a longer duration of anti-glaucoma medication was significantly associated with surgical failure. Propensity score matching analysis showed that the <4.5-year users of anti-glaucoma drugs had significantly higher success rates than the ≥4.5-year users (72% versus 52%; p = 0.04). CONCLUSIONS The prolonged use of multiple glaucoma drugs adversely affected the outcome of μTLO at least at 1 year postoperatively.

Abstract
We report and compare 2 cases of open globe injury with foveal damage incurred while mowing. Case 1 is a healthy 67-year-old man presenting with an intraocular metallic foreign body and eye pain in his right eye after using a mower. The foreign body perforated the cornea's inferior area and damaged the foveal centralis, leading to central scotoma and decreased visual acuity. 27G pars plana vitrectomy was performed, and the final corrected decimal visual acuity was 0.1, but the visual field was preserved, except for the central scotoma. Case 2 is a healthy 50-year-old man presenting open globe injury with an intraocular metallic foreign body while using a mower. The foreign body damaged the fovea and triggered extensive retinal detachment. One month after surgery, proliferative vitreoretinopathy occurred, requiring additional surgery. The final corrected decimal visual acuity dropped to 0.05, resulting in an extensive visual field defect. Both cases of eye trauma were caused by mower injury, but the visual function outcomes differed with the size of the foreign body and the injury severity at the time of onset. Mower eye trauma is preventable, and efforts to educate users on safety measures are needed.

Abstract
AIM Pleomorphic adenoma (PA) consists of heterogeneous histological architecture mixed with epithelioid and mesenchymal forms. Various types of epithelial or myoepithelial malignancies arise from PA, but sarcomas are extremely rare. A HUMARA clonality assay has suggested that PA is clonal in nature. However, clonality of various tumor components of PA would be difficult to determine with this assay. In addition, the results obtained should be carefully interpreted. PLAG1 rearrangements are considered a good molecular marker for neoplasticity in PA. We aimed to clarify the neoplasticity of the various tumor components present in PA using whole-slide fluorescence in situ hybridization (FISH). METHODS Five PA cases positive for PLAG1 rearrangements were examined. Using an immunohistochemistry panel, cell components in PA were classified into eight cell types. To precisely localize PLAG1 rearrangement-positive cell components at the cellular level, sequential retrieval of whole-slide imaging (WSI) data of HE histology and FISH for PLAG1 rearrangement was carried out. RESULTS PLAG1 rearrangements were detected in ductal cells, myoepithelial spindle cells, myoepithelial oncocytic cells, myoepithelial plasmacytoid cells, and mesenchymal chondroid cells, but not in mesenchymal lipid cells, mesenchymal fibrous cells, or vascular endothelial cells. Immunohistochemical PLAG1 expression was restricted to cell components harboring PLAG1 rearrangements. CONCLUSIONS The results of the present study indicate that ductal and myoepithelial, chondroid cells are neoplastic but lipid, fibrous, and endothelial cells are not. PLAG1 immunohistochemistry is useful in discriminating neoplastic from non-neoplastic cell components. These findings may be important for elucidating tumorigenesis and the process of malignant transformation in PA.

Abstract
PURPOSE The purpose of this study was to evaluate the 3-year surgical outcome of the sulcus fixation of Baerveldt glaucoma implant (BGI), focusing on corneal damage. METHODS This prospective observational study included 37 patients who underwent a median of two previous glaucoma surgeries and sulcus fixation of BGI for the first time. Each patient's intraocular pressure (IOP), glaucoma drug score, corneal endothelial cell density (ECD), and logMAR-converted best-corrected visual acuity (VA) were measured preoperatively and postoperatively until 36 months after surgery. Complete success was defined as reduced IOP (5-21 mmHg and >20% rate), without corneal damage (postoperative development of decompensation, unmeasurable ECD, or reduction in ECD of >20%), without loss of light perception, and without additional surgery requirement. Qualified success was defined by excluding the corneal criteria from complete success. RESULTS A total of 51% (19/37) patients experienced complete treatment success, whereas 86% (32/37) had qualified success. The median IOP (glaucoma drug score) decreased from 26 mmHg (5) to 15 mmHg (2) at three years postoperatively. The median postoperative ECD (reduction rate) decreased from 1838 cells/cm2 preoperatively to 1587 cells/mm2 (14%) at one year, 1358 cells/mm2 (26%) at two years, and 1228 cells/mm2 (33%) at three years postoperatively. One month after surgery, the VA was significantly reduced from preoperative values but did not decline after that. CONCLUSION Sulcus fixation of BGI was effective for IOP reduction. However, ECD decreased over time.

Abstract
PURPOSE We compared the 1-year outcomes and early surgery-related complications between 1-quadrant and 2-quadrant microhook ab interno trabeculotomy (TLO). METHODS Medical chart extraction was performed on 47 consecutive patients with 1-quadrant incision and 37 consecutive patients with 2-quadrant incision of trabecular meshwork. Logistic regression analysis was conducted to calculate the propensity score to create a 1:1 match for a comparative analysis of 1-year postoperative success. Success was defined as postoperative intraocular pressure (IOP) between 5-21 mmHg, >20% IOP reduction from baseline, and no additional glaucoma surgery. Outcome-related covariates were age, glaucoma type, mean deviation of visual field tests, preoperative IOP, the number of preoperative glaucoma eye drops and the presence of combined cataract surgery. Thirty eyes from each group were compared. RESULTS The median preoperative IOP was not different between the 1-quadrant and 2-quadrant groups (28.5 mmHg, quartile range 23-33.5 versus 27 mmHg, 23.3-30.0, p = 0.47). There was no difference in median postoperative IOP at 1 year (15 mmHg versus 16 mmHg, p = 0.80). The success rate was 73% in the 1-quadrant group versus 70% in the 2-quadrant group (p = 1.00). The 2-quadrant group had a significantly higher proportion of patients with transiently elevated IOP (47%) than the 1-quadrant (17%; Fisher's exact test, p = 0.02). There was no difference of hyphema formation (Fisher's exact test, p = 0.18). CONCLUSION The 1-year success rate was not significantly different between 1- and 2-quadrant incisions of microhook TLO. However, the 2-quadrant TLO showed significantly higher proportion of post-surgical transient IOP elevation.

Abstract
Purpose Cytomegalovirus (CMV)-related keratouveitis elevates intraocular pressure (IOP). Antiviral therapy does not always control IOP and some patients do not tolerate systemic antiviral therapy because of the side effects. The purpose of this study is to evaluate the clinical characteristics of patients with CMV-related keratouveitis and determine the impact of glaucoma surgeries on the postoperative antiviral therapy regimen. Methods We enrolled twenty-two patients with CMV-DNA-positive keratouveitis between June 2012 and July 2019 in Kobe University Hospital. The following clinical parameters were collected: gender, age, history of previous intraocular surgery, antiviral medications, visual acuity, IOP, glaucoma drug score, corneal endothelial cells density, and the mean deviation of a Humphrey visual field test at the first visit and before and 1 year after glaucoma surgery. Results All twenty-two patients started on oral and/or topical antiviral therapy. Eighteen patients needed glaucoma surgery despite their antiviral medications. Nine patients underwent trabeculotomy (TLO) and nine underwent trabeculectomy (TLE) as the first surgical intervention. Six of patients who initially underwent TLO and two of the patients who initially underwent TLE required additional TLE within 1 year. Each of the 15 patients who underwent at least 1 TLE showed a reduction in the magnitude and variation of IOP and glaucoma drug scores and 13 patients were able to discontinue antiviral therapy. For the remaining 4 patients, IOP and inflammation were controlled but with antiviral medications. Conclusions In patients with CMV-related keratouveitis, TLE decreases and stabilizes IOP and contributes to withdrawal from antiviral medications.

Abstract
INTRODUCTION Leber hereditary optic neuropathy (LHON) is an acute or subacute inherited optic neuropathy caused by mitochondrial mutations. More than 90% of patients with LHON have one of three point mutations (ie, G3460A, G11778A and T14484C). We previously reported that a 12-week session of skin electrical stimulation (SES) with a 2-week interval significantly improved visual acuity and field tests 1 week after the last stimulation and without adverse effects in 10 cases of LHON carrying the mt DNA G11778A mutation. In the present study, we will examine the magnitude and persistence of the efficacy and presence or absence of adverse events using SES with a more frequent stimulation protocol. METHODS AND ANALYSIS This study will be a single-arm, open-labelled, non-randomised clinical study that analyses 15 cases of LHON with G11778A mutation. All participants will take a portable SES device home and perform SES by themselves every other day for 12 weeks. The logarithm for the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) at 1 week after the last SES will be measured as the primary outcome. LogMAR BCVA will be measured at four and 8 weeks after the last SES treatment. The Humphrey visual field sensitivity test using size V stimulation and critical fusion frequency at 1, 4 and 8 weeks after the last SES session will be secondary outcome measurements. Slit-lamp examination, optical coherence tomography and specular microscopy will also be performed to verify the safety of SES. ETHICS AND DISSEMINATION The protocol was approved by the Institutional Review Board at Kobe University, Japan (Approval No.C190030). This study is in progress and deserves Pre-result. All documents communicating with the ethics committee will be reposited by the researcher. Modifications to the protocol will be reviewed by the ethics committee and implemented after approval. Data monitoring will be performed by a researcher who is not involved in the study every 6 months after approval. The research summary results will be registered in the Japan Registry of Clinical Trials (jRCTs) and made available to participants in accordance with the terms described in the documents. In addition, the results of this study will be presented at domestic and international meetings and published in peer-reviewed journals within a year after data is fixed. TRIAL REGISTRATION NUMBER jRCTs052200033.

Abstract
Abstract
Background
Sarcopenia and malnutrition are associated with poor clinical outcome in patients with chronic heart failure. However, there is little information available on the prognostic significance of the combination of sarcopenia and malnutrition in patients with acute decompensated heart failure (ADHF), relating to reduced or preserved left ventricular ejection fraction (HFrEF or HFpEF).
Methods
We prospectively studied 543 consecutive ADHF patients who survived to discharge (HFrEF [LVEF <45%] n=245 and HFpEF [LVEF≥45%] n=298). At the discharge, sarcopenia and malnutrition was evaluated by free-fat mass index (FFMI) and geriatric nutrition risk index (GNRI), respectively. FFMI was calculated as follows: FFMI = (7.38 + 0.02908 × urinary creatinine [mg/day])/ (height in meter)2. Sarcopenia was defined as FFMI <17 kg/m2 in men and <15 kg/m2 in women. GNRI was calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × BMI/22, and malnutrition was defined as GNRI<92. The endpoint was all-cause death.
Results
During a follow-up period of 2.8±1.4 years, 161 patients had all-cause death. Multivariate Cox analysis showed that both FFMI and GNRI were independently associated with all-cause death in both HFrEF (p=0.0064 and p<0.0001, respectively) and HFpEF patients (p=0.0140 and p=0.0007, respectively) after adjustment for relevant baseline clinical and study characteristics. In HFrEF, patients with both sarcopenia and malnutrition had a significantly higher risk of the total mortality than those with either or none of them. On the other hand, in HFpEF, patients with both and either sarcopenia or malnutrition had a significantly higher risk of the total mortality than those with none of them, while there was no significant difference in the risk between both and either sarcopenia or malnutrition.
Conclusions
Sarcopenia or malnutrition at discharge was associated with all-cause death even in ADHF patients, irrespective of reduced or preserved LVEF. The combination of sarcopenia and malnutrition could provide prognostic information in ADHF patients with reduced LVEF.

Abstract
We report on a joint experimental and theoretical study of photoelectron circular dichroism (PECD) in methyloxirane. By detecting O 1s photoelectrons in coincidence with fragment ions, we deduce the molecule's orientation and photoelectron emission direction in the laboratory frame. Thereby, we retrieve a fourfold differential PECD clearly beyond 50%. This strong chiral asymmetry is reproduced by ab initio electronic structure calculations. Providing such a pronounced contrast makes PECD of fixed-in-space chiral molecules an even more sensitive tool for chiral recognition in the gas phase.

Abstract
The interaction of intense femtosecond x-ray pulses with molecules sensitively depends on the interplay between multiple photoabsorptions, Auger decay, charge rearrangement, and nuclear motion. Here, we report on a combined experimental and theoretical study of the ionization and fragmentation of iodomethane (CH_{3}I) by ultraintense (∼10^{19} W/cm^{2}) x-ray pulses at 8.3 keV, demonstrating how these dynamics depend on the x-ray pulse energy and duration. We show that the timing of multiple ionization steps leading to a particular reaction product and, thus, the product's final kinetic energy, is determined by the pulse duration rather than the pulse energy or intensity. While the overall degree of ionization is mainly defined by the pulse energy, our measurement reveals that the yield of the fragments with the highest charge states is enhanced for short pulse durations, in contrast to earlier observations for atoms and small molecules in the soft x-ray domain. We attribute this effect to a decreased charge transfer efficiency at larger internuclear separations, which are reached during longer pulses.

Abstract
α-RuCl3 is a major candidate for the realization of the Kitaev quantum spin liquid, but its zigzag antiferromagnetic order at low temperatures indicates deviations from the Kitaev model. We have quantified the spin Hamiltonian of α-RuCl3 by a resonant inelastic x-ray scattering study at the Ru L3 absorption edge. In the paramagnetic state, the quasi-elastic intensity of magnetic excitations has a broad maximum around the zone center without any local maxima at the zigzag magnetic Bragg wavevectors. This finding implies that the zigzag order is fragile and readily destabilized by competing ferromagnetic correlations. The classical ground state of the experimentally determined Hamiltonian is actually ferromagnetic. The zigzag state is stabilized by quantum fluctuations, leaving ferromagnetism – along with the Kitaev spin liquid – as energetically proximate metastable states. The three closely competing states and their collective excitations hold the key to the theoretical understanding of the unusual properties of α-RuCl3 in magnetic fields. RuCl3 has stood out as a prime candidate in the search for quantum spin liquids; however, its antiferromagnetic ordering at low temperature suggests deviations from typical QSL models. Here, using resonant inelastic x-ray scattering, the authors provide a comprehensive determination of the low energy effective Hamiltonian.

Abstract
Following the accident at Fukushima Daiichi nuclear power plant in 2011, a series of health literacy training workshops for local health workers was developed and implemented. This study aimed to analyse who among the intended audience gained the greatest benefit from the training. Nine health workers attended a workshop consisting of classroom training and a follow-up feedback assessment of materials they created in the workshop. The materials were assessed by a total of 131 intended readers. Using Sakai's tool, those items asking readers to rate the accessibility of written information were used to compare the materials before and after revision. The total score for Sakai's measure showed a significant improvement, and the elderly and those without regular doctor visits were more likely to notice improvements after revision. Such health literacy training could serve as a model programme to prevent inequity in access to health information in the face of a regional health crisis.

Abstract
Three pathological grading systems advocated by Perzin/Szanto, Spiro, and van Weert are currently used for adenoid cystic carcinoma (AdCC). In these systems, the amount or presence of the solid tumor component in AdCC specimens is an important index. However, the “solid tumor component” has not been well defined. Salivary AdCC cases (N = 195) were collected after a central pathology review. We introduced a novel criterion for solid tumor component, minAmax (minor axis maximum). The largest solid tumor nest in each AdCC case was histologically screened, the maximum oval fitting the solid nest was estimated, and the length of the minor axis of the oval (minAmax) was measured. The prognostic cutoff for the minAmax was determined using training and validation cohorts. All cases were evaluated for the four grading systems, and their prognostic impact and interobserver variability were examined. The cutoff value for the minAmax was set at 0.20 mm. Multivariate prognostic analyses showed the minAmax and van Weert systems to be independent prognostic tools for overall, disease‐free, and distant metastasis‐free survival while the Perzin/Szanto and Spiro systems were selected for overall survival but not for disease‐free or distant metastasis‐free survival. The highest hazard ratio for overall survival (11.9) was obtained with the minAmax system. The reproducibility of the minAmax system (kappa coefficient of 0.81) was scored as very good while those of the other three systems were scored as moderate. In conclusion, the minAmax is a simple, objective, and highly reproducible grading system useful for prognostic stratification for salivary AdCC.

Abstract
We report a rare case of granulomatosis with polyangiitis (GPA) presenting with bilateral orbital apex syndrome (OAS). A 73-year-old woman with a history of endoscopic sinus surgery for ethmoidal sinusitis experienced a sudden decrease in visual acuity (VA) of both eyes. At the initial examination, her VA had decreased to 0.01 in the right eye and 0.03 in the left eye, and eye movement in both eyes was mildly limited in all directions. Visual field tests of both eyes showed a large central scotoma. Laboratory tests revealed an elevation of myeloperoxidase-anti-neutrophil cytoplasmic antibody. Facial computed tomography demonstrated a thickened mucosal membrane in the entire ethmoidal sinus, and the posterosuperior walls of Onodi cells filled with infiltrative lesions had thinned. Orbital magnetic resonance imaging showed severe inflammation in the orbital apex. From these clinical findings, the patient was diagnosed with GPA presenting with OAS associated with ethmoid sinusitis. Emergent endoscopic sinus surgery was performed for biopsy and debridement of the ethmoidal and sphenoid sinusitis to decompress the optic nerve. One day after endoscopic sinus surgery, the patient's VA and visual field were improved, and steroid pulse therapy was commenced postoperatively. Four days later, VA had recovered to 1.0 in both eyes, and eye movement and visual field had were improved. Although OAS is a rare manifestation, early surgical treatment should be considered when the orbital lesion presents as risk of rapid deterioration of visual function in patients with GPA.

Abstract
Abstract
Background and introduction
The difference in cardiovascular disease risk between age-matched women and men narrows as transition through menopause in observational studies. Estrogen exerts complex physiological effects via its non-nuclear and nuclear actions. Experimental studies have shown that endothelial estrogen receptors mediate vasoprotection via endothelial nitric oxide production, reendothelialization, and atherosclerosis. Prior studies in vitro addressed estrogen's effects on endothelial cells and vascular smooth muscle cells, leading to vasoprotection. However, the in vivo evidences are lacking for beneficial effects of endothelium non-nuclear ERα signaling on vascular remodelling in response to injury.
Purpose
This study aims to clarify the impact of endothelial ERα non-nuclear signaling in the vasoprotection, using a novel mouse model lacking tissue-specific ERα non-nuclear signaling.
Methods
We identified the amino acids of ERα which were responsible for its binding to p85α subunit of phosphatidylinositol 3-kinase in vitro. We generated a novel mouse model in which non-nuclear signaling of ERα was ablated in endothelial cells by crossing Tie2-Cre transgenic mice with floxed ERα mutants (RR259/260AA) in which p85α and ERα interaction was disrupted.
Results
In endothelial cells isolated from ERαKI/KITie2 cre/+ animals, E2 failed to induce phosphorylation of Akt, confirming the absence of ERα non-nuclear signaling. Baseline characteristics at 8 to 12 weeks of age were undistinguishable between the genotypes, including body weight, systolic blood pressure, uterine weight and echocardiographic fractional shortening. We then assessed how vascular remodelling process was impacted in a carotid artery wire injury model. Histological analyses with Elastica van Gieson staining two weeks after injury revealed that estrogen dependent suppression of remodelling response (intima to medial ratio) was abolished in ERαki/kiTie2cre/+mice (P=0.0004). Masson's Trichrome staining showed that in the presence of E2 fibrosis was significantly higher in ERαki/kiTie2cre/+ mice than ERαki/kiTie2cre/− mice (P=0.0015).
Conclusions
We generated a novel mouse model for tissue-specific ablation of ERα non-nuclear signaling by interfering ERα-PI3K interaction. Our results demonstrate that the pivotal role for ERα non-nuclear signaling of endothelial cells in carotid arterial protection following injury with its minimal impact on baseline cardiovascular phenotype.

Abstract
Mucoepidermoid carcinoma (MEC) is rare, but the most common primary malignancy of the salivary gland and not infrequent in young individuals. CRTC1/3-MAML2 fusions are frequently detected in MEC and are useful as a diagnostic biomarker. However, there has been debate as to whether the fusions have prognostic significance. In this study, we retrospectively collected 153 salivary gland MEC cases from 11 tertiary hospitals in Japan. As inclusion criteria, the MEC patients in this study had curative surgery as the initial treatment, received no preoperative treatment, and had no distant metastasis at the time of the initial surgery. The MEC diagnosis was validated by a central pathology review by five expert salivary gland pathologists. The CRTC1/3-MAML2 fusions were detected using FISH and RT-PCR. In 153 MEC cases, 90 (58.8%) were positive for CRTC1/3-MAML2 fusions. During the follow-up period, 28 (18.3%) patients showed tumor recurrence and 12 (7.8%) patients died. The presence of the fusions was associated with favorable tumor features. Of note, none of the fusion-positive patients died during the follow-up period. Statistical analysis showed that the presence of the fusions was a prognostic indicator of a better overall survival in the total and advanced-stage MEC cohorts, but not in the early-stage MEC cohort. In conclusion, CRTC1/3-MAML2 fusions are an excellent biomarker for favorable overall survival of patients with salivary gland MEC.

Abstract
BACKGROUND Preoperative diagnosis of salivary gland tumors (SGTs) by fine-needle aspiration (FNA) cytology is challenging. Next-generation sequencing (NGS)-based assays for somatic mutations have a great advantage in that a large number of genes can be analyzed simultaneously. Although NGS may have an enormous diagnostic potential in cytology, to our knowledge, the significance of NGS in SGT cytology remains to be clarified. METHODS In this pilot study, we retrospectively examined 32 frozen SGT samples obtained at surgery (14 malignant and 18 benign). After the stored frozen tumor tissues were thawed, aspirate samples were obtained using 22-gauge needles and subjected to smear tumor samples and to DNA extraction for an NGS assay employing the Illumina AmpliSeq Cancer Hotspot Panel v2. The results were correlated to preoperative cytological diagnosis. RESULTS The preoperative diagnoses obtained by FNA cytology included 23 negative lesions (no malignancy in 6 and benign tumor in 17) and nine positive lesions (suspicious for malignancy in 4 and malignancy in five), providing a sensitivity and a specificity of 9/14 (64%) and 18/18 (100%), respectively. The NGS assay detected somatic mutations in 10/14 malignant and 1/18 benign SGT cases, providing a sensitivity and a specificity of 71% and 94%, respectively. CONCLUSION The NGS assay may be helpful for detecting the malignant potential in SGT cases and can be used as an ancillary test for SGT cytology.

Abstract
The Weyl semimetal (WSM), which hosts pairs of Weyl points and accompanying Berry curvature in momentum space near Fermi level, is expected to exhibit novel electromagnetic phenomena. Although the large optical/electronic responses such as nonlinear optical effects and intrinsic anomalous Hall effect (AHE) have recently been demonstrated indeed, the conclusive evidence for their topological origins has remained elusive. Here, we report the gigantic magneto-optical (MO) response arising from the topological electronic structure with intense Berry curvature in magnetic WSM Co3Sn2S2. The low-energy MO spectroscopy and the first-principles calculation reveal that the interband transitions on the nodal rings connected to the Weyl points show the resonance of the optical Hall conductivity and give rise to the giant intrinsic AHE in dc limit. The terahertz Faraday and infrared Kerr rotations are found to be remarkably enhanced by these resonances with topological electronic structures, demonstrating the novel low-energy optical response inherent to the magnetic WSM.

Abstract
OBJECTIVES This study aimed to assess and compare postoperative bleeding occurrence after dental extraction in medically compromised elderly patients under anticoagulant therapy. MATERIALS AND METHODS This retrospective study included medically compromised elderly patients aged ≥ 65 years who were taking apixaban, dabigatran, edoxaban, rivaroxaban, or warfarin and had undergone single or multiple dental extractions. The primary outcome measure was postoperative bleeding occurrence, which was defined as oozing or marked hemorrhage from 24 h to 7 days after dental extraction. Postoperative bleeding occurrence was calculated for each anticoagulant and compared using Fisher's exact test, followed by multiple comparisons. RESULTS Two hundred thirty-two patients met the inclusion criteria. The highest postoperative bleeding occurrence was recorded for rivaroxaban (12/37: 32.4%), followed by apixaban (8/44: 18.2%), warfarin (17/98: 17.3%), and edoxaban (2/35: 5.7%). Patients taking dabigatran did not present postoperative bleeding (0/18: 0%). Fisher's exact test, followed by multiple comparison tests, revealed a significant among-anticoagulant difference (p = 0.0095). Postoperative bleeding was significantly higher in patients taking rivaroxaban than in those taking edoxaban or dabigatran (p = 0.03088). CONCLUSIONS Within the limitations of this retrospective study design, these findings suggest that different anticoagulants may affect postoperative bleeding occurrence after dental extraction among medically compromised elderly patients. CLINICAL RELEVANCE Clinicians should carefully consider postoperative bleeding after dental extraction in patients taking anticoagulant therapy, especially rivaroxaban.

Abstract
Abstract
Background
Air pollution is a serious problem in India. According to World Bank's data in 2015, about 660 million people were categorized as poor (US$3.20 per day per capita) in India and the proportion to total the population was 50.4 %. Even though the number and proportion are large, the effects on the poor people have not been studied very well. We measured the effects of air pollution on children of the poor and compared between urban and rural area in West Bengal, India.
Methods
24 male students (12.5 ± 0.8 years) in urban area (Kolkata) and 20 male students (12.5 ± 0.5 years) in rural area (Jata) were recruited. We measured fractional exhaled nitric oxide (FeNO), which was index of airway inflammation and checked allergic symptoms. The survey was conducted in January (dry season) and August (rainy season) 2019 to confirm a seasonal difference. Air quality index (AQI) in each area was used for index of air pollution.
Results
Average AQI was 335 (Kolkata) and 155 (Haldia: near Jata) for 2 months from December 2018 to January 2019, while average AQI was 51 (Kolkata) and 38 (Haldia) for 2 months from July to August 2019. As for FeNO in dry season, the value in Kolkata was 24.9 ± 16.1 and the value in Jata was 11.7 ± 3.5. As for FeNO in rainy season, the value in Kolkata was 22.3 ± 17.5 and the value in Jata was 16.8 ± 6.7. The value of FeNO in Kolkata was higher than Jata in either season. Although a seasonal difference was not detected in Kolkata, the value in dry season was lower than in rainy season in Jata. The prevalence of allergic symptoms in dry season was higher than in rainy season in Kolkata. On the other hand, there was no difference in the prevalence between dry and rainy season in Jata.
Conclusions
Even though AQI and the prevalence of allergic symptoms decreased, the value of FeNO did not decrease in Kolkata. Because AQI decreased, indoor air pollution might have influenced on airway. It is supposed that prevention of indoor air pollution is important.
Key messages
Airway of children in urban area may be influenced on by air pollution more than in rural area. Indoor air pollution may influence on children of the poor more than outdoor air pollution.

Abstract
AIM To differentiate between infectious and non-infectious diseases occurring in immunocompromised patients without acquired immunodeficiency syndrome (AIDS) using high-resolution computed tomography (HRCT). MATERIALS AND METHODS HRCT images of 555 patients with chest complications were reviewed retrospectively. Infectious diseases (n=341) included bacterial pneumonia (n=123), fungal infection (n=80), septic emboli (n=11), tuberculosis (n=15), pneumocystis pneumonia (n=101), and cytomegalovirus pneumonia (n=11), while non-infectious diseases (n=214) included drug toxicity (n=84), infiltration of underlying diseases (n=83), idiopathic pneumonia syndrome (n=34), diffuse alveolar haemorrhage (n=8), and pulmonary oedema (n=5). Lung parenchymal abnormalities were compared between the two groups using the χ2 test and multiple logistic regression analysis. RESULTS The χ2 test results showed significant differences in many HRCT findings between the two groups. Multiple logistic regression analysis results indicated the presence of nodules with a halo and the absence of interlobular septal (ILS) thickening were the significant indicators that could differentiate infectious from non-infectious diseases. ILS thickening was generally less frequent among most infectious diseases and more frequent among most non-infectious diseases, with a good odds ratio (7.887, p<0.001). The sensitivity and accuracy for infectious diseases in the absence of ILS thickening were better (70% and 73%, respectively) than those of nodules with a halo (19% and 48%, respectively), while the specificity in the nodules with a halo was better (93%) than that of ILS thickening (78%). CONCLUSIONS The presence of nodules with a halo or the absence of ILS thickening tends to suggest infectious disease. Specifically, ILS thickening seems to be a more reliable indicator.

Abstract
OBJECTIVE To evaluate cardiovascular response in patients on warfarin and hypertensive patients not on warfarin during dental extraction. MATERIALS AND METHODS This retrospective study included 53 patients who had undergone dental extraction while on warfarin (mean age 78.8 ± 6.3 years, 26 men) and 66 with hypertension who had undergone dental extraction but were not on warfarin (mean age 77.4 ± 6.8 years, 22 men). Vital signs were monitored in both groups during extraction. RESULTS The highest systolic blood pressure (SBP) values (mean 150.1 ± 21.1 mmHg) were observed in patients on warfarin before (9.0%) and after (10.3%) administration of local anesthesia (LA), during extraction (39.7%), and during (33.3%) and after (7.7%) suturing (n = 78; p < 0.01), and in hypertensive patients not receiving warfarin (160.6 ± 24.8 mmHg) before (19.2%) and after (27.3%) administration of LA, during extraction (29.3%), and during (18.2%) and after (6.1%) suturing (n = 99; p < 0.01). The highest SBP was linearly correlated with SBP before administration of LA in patients on warfarin (highest SBP = 0.9415 × SBP before LA + 23.243, R2 = 0.75481) and in hypertensive patients not on warfarin (highest SBP = 1.0027 × SBP before LA + 15.789, R2 = 0.60341). CONCLUSIONS The highest SBP was not distributed evenly between patients on warfarin and hypertensive patients not on warfarin during dental extraction and was strongly associated with SBP before LA regardless of anticoagulant status. CLINICAL RELEVANCE Thorough management of SBP is required in patients on warfarin to avoid thromboembolism and major hemorrhagic complications. Knowing the SBP value before dental treatment would help predict the risk of cardiovascular complications.

Abstract
Purpose We report a case of neurosarcoidosis that presented simultaneously with oculomotor nerve palsy, contralateral abducens nerve palsy, and paresthesia of both lower limbs. Observations A 69-year-old Japanese woman who suffered from repeated diplopia and lower-limb paresthesia was referred to our hospital. Ophthalmic findings included oculomotor nerve and contralateral abducens nerve palsies. No remarkable abnormalities were detected via enhanced brain magnetic resonance imaging (MRI), chest X-ray, and cerebrospinal fluid analysis. Chest computed tomography (CT) was performed to exclude neoplastic lesions; this revealed right hilar lymphadenopathy, and positron emission tomography MRI showed strong 18-F fluorodeoxyglucose uptake in the hilar lymph node. Biopsy of the lymph node showed non-caseating epithelioid granulomatous tissue, leading to a diagnosis of probable neurosarcoidosis. After the initiation of oral prednisolone treatment, the patient experienced complete remission without any recurrence. Conclusions and importance When examining a patient presenting with multiple cranial neuropathies of unknown cause, neurosarcoidosis should be considered as a differential diagnosis and chest CT should be performed even when the chest X-ray and angiotensin-converting enzyme appears normal.
