Abstract
A strong relationship between Alzheimer's disease (AD) and vascular dysfunction has been the focus of increasing attention in aging societies. In the present study, we examined the long-term effect of scallop-derived plasmalogen (sPlas) on vascular remodeling-related proteins in the brain of an AD with cerebral hypoperfusion (HP) mouse model. We demonstrated, for the first time, that cerebral HP activated the axis of the receptor for advanced glycation endproducts (RAGE)/phosphorylated signal transducer and activator of transcription 3 (pSTAT3)/provirus integration site for Moloney murine leukemia virus 1 (PIM1)/nuclear factor of activated T cells 1 (NFATc1), accounting for such cerebral vascular remodeling. Moreover, we also found that cerebral HP accelerated pSTAT3-mediated astrogliosis and activation of the nucleotide-binding domain and leucine-rich repeat protein 3 (NLRP3) inflammasome, probably leading to cognitive decline. On the other hand, sPlas treatment attenuated the activation of the pSTAT3/PIM1/NFATc1 axis independent of RAGE and significantly suppressed NLRP3 inflammasome activation, demonstrating the beneficial effect on AD.

Abstract
Background NADPH oxidase 2 (NOX2) is an important source of reactive oxygen species (ROS). Activated NOX2 may contribute to Alzheimer's disease (AD). Our previous studies showed that a novel vitamin E mixture, Tocovid, had potential neuroprotective effects in a stroke mice model and an AD cell model. Objective The aim of this study was two-fold: to assess whether long-term Tocovid treatment can regulate NOX2, and the therapeutic effects of long-term administration of Tocovid to an AD mice model. Methods Therapeutic effects of long-term administration of Tocovid (200 mg/kg /day) on an Aβ-overexpressed transgenic AD mice model (APP23, n = 8) was investigated. The therapeutic effect of Tocovid in 16-month-old mice compared with the no-treatment APP23 group (n = 9) was assessed. Results Tocovid treatment strongly improved motor and memory deficits of APP23 mice by attenuating NOX2 expression, oxidative stress, neuroinflammation, neurovascular unit dysfunction, synaptic alteration, and Aβ deposition after 16 months. Conclusion These findings suggest that NOX2 is a potential target in AD pathology. Long-term administration of Tocovid may be a promising candidate for AD treatment.

Abstract
The differential diagnosis of myelopathy in patients with malignancies may be challenging, as a spinal biopsy is not always applicable. A 66-year-old woman who had shown transient double vision and nausea developed spasticity and impaired deep sensation in both feet. Magnetic resonance imaging showed abnormal gadolinium enhancement of the brainstem, spinal meninges, and nerve root. Cerebrospinal fluid (CSF) revealed mild pleocytosis and elevated protein and decreased glucose levels, although CSF cytology was normal. Lung carcinoma was simultaneously detected, and noncaseating granuloma was detected from the hilar and axillary lymph nodes, so she was diagnosed with sarcoid-associated myelopathy. Her symptoms were kept stable by intravenous methylprednisolone, oral prednisolone, and methotrexate. This is the first case of sarcoid-associated myelopathy accompanied by lung cancer, suggesting the importance of clinical course, repetitive CSF cytology, and a biopsy of the lymph nodes to distinguish sarcoid-associated myelopathy from meningeal metastasis in patients with malignancies.

Abstract
Amelogenin plays a crucial role in tooth enamel formation, and mutations on X-chromosomal amelogenin cause X-linked amelogenesis imperfecta (AI). Amelogenin pre-messenger RNA (mRNA) is highly alternatively spliced, and during alternative splicing, exon4 is mostly skipped, leading to the formation of a microRNA (miR-exon4) that has been suggested to function in enamel and bone formation. While delivering the functional variation of amelogenin proteins, alternative splicing of exon4 is the decisive first step to producing miR-exon4. However, the factors that regulate the splicing of exon4 are not well understood. This study aimed to investigate the association between known mutations in exon4 and exon5 of X chromosome amelogenin that causes X-linked AI, the splicing of exon4, and miR-exon4 formation. Our results showed mutations in exon4 and exon5 of the amelogenin gene, including c.120T>C, c.152C>T, c.155C>G, and c.155delC, significantly affected the splicing of exon4 and subsequent miR-exon4 production. Using an amelogenin minigene transfected in HEK-293 cells, we observed increased inclusion of exon4 in amelogenin mRNA and reduced miR-exon4 production with these mutations. In silico analysis predicted that Ser/Arg-rich RNA splicing factor (SRSF) 2 and SRSF5 were the regulatory factors for exon4 and exon5 splicing, respectively. Electrophoretic mobility shift assay confirmed that SRSF2 binds to exon4 and SRSF5 binds to exon5, and mutations in each exon can alter SRSF binding. Transfection of the amelogenin minigene to LS8 ameloblastic cells suppressed expression of the known miR-exon4 direct targets, Nfia and Prkch, related to multiple pathways. Given the mutations on the minigene, the expression of Prkch has been significantly upregulated with c.155C>G and c.155delC mutations. Together, we confirmed that exon4 splicing is critical for miR-exon4 production, and mutations causing X-linked AI in exon4 and exon5 significantly affect exon4 splicing and following miR-exon4 production. The change in miR-exon4 would be an additional etiology of enamel defects seen in some X-linked AI.

Abstract
The T2K experiment presents new measurements of neutrino oscillation parameters using 19.7 ( 16.3 ) × 10 20 protons on target (POT) in (anti-)neutrino mode at the far detector (FD). Compared to the previous analysis, an additional 4.7 × 10 20 POT neutrino data was collected at the FD. Significant improvements were made to the analysis methodology, with the near-detector analysis introducing new selections and using more than double the data. Additionally, this is the first T2K oscillation analysis to use NA61/SHINE data on a replica of the T2K target to tune the neutrino flux model, and the neutrino interaction model was improved to include new nuclear effects and calculations. Frequentist and Bayesian analyses are presented, including results on sin 2 θ 13 and the impact of priors on the δ CP measurement. Both analyses prefer the normal mass ordering and upper octant of sin 2 θ 23 with a nearly maximally CP-violating phase. Assuming the normal ordering and using the constraint on sin 2 θ 13 from reactors, sin 2 θ 23 = 0 . 561 - 0.032 + 0.021 using Feldman-Cousins corrected intervals, and Δ m 32 2 = 2 . 494 - 0.058 + 0.041 × 10 - 3 eV 2 using constant Δ χ 2 intervals. The CP-violating phase is constrained to δ CP = - 1 . 97 - 0.70 + 0.97 using Feldman-Cousins corrected intervals, and δ CP = 0 , π is excluded at more than 90% confidence level. A Jarlskog invariant of zero is excluded at more than 2 σ credible level using a flat prior in δ CP , and just below 2 σ using a flat prior in sin δ CP . When the external constraint on sin 2 θ 13 is removed, sin 2 θ 13 = 28 . 0 - 6.5 + 2.8 × 10 - 3 , in agreement with measurements from reactor experiments. These results are consistent with previous T2K analyses.

Abstract
Anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) immune-mediated necrotizing myopathy (IMNM) is a neuromuscular disorder that presents muscle weakness in proximal extremities and/or the trunk with an elevation of creatine kinase (CK). Young and asymptomatic anti-HMGCR IMNM patients are very rare and a treatment regimen has not been established. The present case, a 17-year-old woman without any muscular symptoms, only showed hyperCKemia that was detected by chance. After close examinations, including a muscle biopsy and antibody search, she was diagnosed as anti-HMGCR IMNM, and initial treatment with methotrexate and continuous intravenous immunoglobulin seemed to be effective. The present case is the unusually young asymptomatic case of anti-HMGCR IMNM. The diagnosis was successfully made, leading to the early introduction of a treatment. Given the course of this case, we believe that the preceding antibody testing is one of the diagnostic option for rhabdomyolysis.

Abstract
Objective During the coronavirus disease 2019 (COVID-19) pandemic, many social activities have moved online using applications for digital devices (e.g. computers, smartphones). We investigated the needs of telemedicine and trends in medical status and social care situations of Japanese patients with neurological disorders in order to estimate their affinity for an online telemedicine application. Methods We designed an original questionnaire for the present study that asked participants what problems they had with hospital visits, how the COVID-19 pandemic had affected their lives, and whether or not they would like to receive telemedicine. Patients The present study included volunteer caregivers, participants with Parkinson's disease (PD), epilepsy, stroke, dementia, immune-mediated neurological disease (IMMD), spinocerebellar degeneration (SCD), amyotrophic lateral sclerosis (ALS), headache, myopathy, and other neurological diseases from Okayama University Hospital. Results A total of 29.6% of patients wanted to use telemedicine. Patients with headaches (60.0%) and epilepsy (38.1%) were more likely to want to use telemedicine than patients with PD (17.8%) or stroke (19.0%). Almost 90% of patients had access to a digital device, and there was no association between favoring telemedicine, ownership of a digital device, hospital visiting time, or waiting time at the hospital, although age was associated with motivation to telemedicine use (52.6 vs. 62.2 years old, p<0.001). Conclusion We can contribute to the management of the COVID-19 pandemic and the medical economy by promoting telemedicine, especially for young patients with headaches or epilepsy.

Abstract
We report a search for cosmic-ray boosted dark matter with protons using the 0.37 megaton×years data collected at Super-Kamiokande experiment during the 1996-2018 period (SKI-IV phase). We searched for an excess of proton recoils above the atmospheric neutrino background from the vicinity of the Galactic Center. No such excess is observed, and limits are calculated for two reference models of dark matter with either a constant interaction cross section or through a scalar mediator. This is the first experimental search for boosted dark matter with hadrons using directional information. The results present the most stringent limits on cosmic-ray boosted dark matter and exclude the dark matter-nucleon elastic scattering cross section between 10^{-33}cm^{2} and 10^{-27}cm^{2} for dark matter mass from 1 MeV/c^{2} to 300 MeV/c^{2}.

Abstract
Amyotrophic lateral sclerosis (ALS) is characterized by progressive loss of motor neurons. Multilineage-differentiating stress-enduring (Muse) cells are unique endogenous stem cells that show therapeutic effects on motor function in ALS mouse models. We conducted a single-center open phase II clinical trial to evaluate the safety and clinical effects of repeated intravenous injections of an allogenic Muse cell-based product, CL2020, in patients with ALS. Five patients with ALS received CL2020 intravenously once a month for a total of six doses. The primary endpoints were safety and tolerability, and the secondary endpoint was the rate of change in the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) score. In addition, serum tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), sphingosine-1-phosphate (S1P), cerebrospinal fluid chitotriosidase-1 (CHIT-1), and neurofilament light chain (NfL) levels were evaluated. The CL2020 treatment was highly tolerated without serious side effects. The ALSFRS-R score change trended upward at 12 months post-CL2020 treatment compared with that at 3 months pre-administration, but the difference was not statistically significant. Among five patients diagnosed with ALS, three exhibited a decrease in the rate of ALSFRS-R score change, one demonstrated an increase, and another showed no change. In addition, the patients' serum IL-6 and TNF-α levels and cerebrospinal fluid CHIT-1 and NfL levels increased for up to 6 months post-treatment; however, their serum S1P levels continuously decreased over 12 months. These findings indicate a favorable safety profile of CL2020 therapy. In the near future, a double-blind study of a larger number of ALS patients should be conducted to confirm the efficacy of ALS treatment with CL2020.

Abstract
Human cord blood-endothelial progenitor cells (hCB-EPCs) isolated from the human umbilical cord can be used to repair damaged arteries. In this study, we used an animal model with pathological changes that mimics artery wall damage caused by stent retrievers in humans. We injected hCB-EPCs to investigate their effect on endothelial hyperplasia and dysfunction during intimal repair. Four groups were established based on the length of reperfusion (3 and 28 days), as well as the presence or absence of hCB-EPC therapy. Damage to the internal carotid artery was evaluated by hematoxylin-eosin and immunohistochemical staining. Stroke volume was not significantly different between non-EPC and EPC groups although EPC treatment alleviated intimal hyperplasia 28 days after intimal damage. Vascular endothelial growth factor (VEGF) and eNOS expression were significantly higher in the EPC-treated group than in the non-EPC group 3 days after intimal damage. In addition, MMP9 and 4HNE expression in the EPC-treated group was significantly lower than in the non-EPC group. Ultimately, this study found that venous transplantation of hCB-EPCs could inhibit neointimal hyperplasia, alleviate endothelial dysfunction, suppress intimal inflammation, and reduce oxidative stress during healing of intimal damage.

Abstract
We report 2 cases of reversible cerebral vasoconstriction syndrome (RCVS) associated with postpartum. In case 1, a 26-year-old woman developed sudden-onset headache, nausea, and vomiting 1 h after an uncomplicated vaginal delivery. In case 2, a 27-year-old woman developed generalized seizures 9 days after an uncomplicated vaginal delivery. In both cases, initial angiographic studies showed no significant vasoconstriction; however, repeat studies revealed reversible vasoconstriction. Serial magnetic resonance imaging (MRI) revealed transient brain lesions during 6 months. RCVS remains poorly characterized, misdiagnosed, and under-recognized. Serial MRI and magnetic resonance angiographic findings may contribute to diagnosis of RCVS.

Abstract
Abstract
Background
Cardiopulmonary arrest (CPA) is the most serious presentation of acute myocardial infarction (AMI). However, the frequency and prognostic impact of CPA in young patients with AMI have been still unclear.
Objectives
This study aimed to characterize AMI in young patients who underwent primary percutaneous coronary intervention using large-scale nationwide all-comer registry data in Japan (J-PCI registry).
Methods
Data on risk factor profiles, clinical features, post-procedural complications, and in-hospital outcomes were reviewed within the J-PCI registry between 2014 and 2018.
Results
Among 213,297 patients with AMI, 23,985 (11.2%) were young (age, 20–49 years). Compared with the older group (age, 50–79 years; n=189,312), the young group included a higher number of men, smokers, patients with dyslipidemia, and patients with single-vessel disease, and a lower number of patients with hypertension and diabetes. Despite favorable clinical profiles, younger age was associated with a higher rate of presentation with CPA (Figure 1). Further, concomitant CPA was strongly associated with in-hospital mortality in the young group (Table 1).
Conclusions
Young patients with AMI presented a higher risk of CPA than older patients, which was strongly associated with in-hospital mortality.

Abstract
Background: The oral ingestion of scallop-derived plasmalogen (sPlas) significantly improved cognitive function in Alzheimer’s disease (AD) patients. Objective: However, the effects and mechanisms of sPlas on AD with chronic cerebral hypoperfusion (CCH), a class of mixed dementia contributing to 20–30% among the dementia society, were still elusive. Methods: In the present study, we applied a novel mouse model of AD with CCH to investigate the potential effects of sPlas on AD with CCH. Results: The present study demonstrated that sPlas significantly recovered cerebral blood flow, improved motor and cognitive deficits, reduced amyloid-β pathology, regulated neuroinflammation, ameliorated neural oxidative stress, and inhibited neuronal loss in AD with CCH mice at 12 M. Conclusion: These findings suggest that sPlas possesses clinical and pathological benefits for AD with CCH in the novel model mice. Furthermore, sPlas could have promising prevention and therapeutic effects on patients of AD with CCH.

Abstract
OBJECTIVES Recently, the standard of care for advanced urothelial cancer (UC) has been changed by developing immune-checkpoint inhibitors (ICIs). However, its response rate is limited to 20-30%. The identification of biomarkers to predict the therapeutic effects of ICIs is urgently needed. The present study explored the association between immunohistochemical biomarkers and clinical outcomes in UC patients treated with pembrolizumab. PATIENTS AND METHODS A total of 85 patients with UC who received pembrolizumab after chemotherapy from January 2018 to May 2020 were retrospectively reviewed. Tumor tissues were obtained for immunohistochemical study from 47 out of 85 patients. The protein expressions of PD-L1, WT1, Nectin-4, CD4, CD8, Foxp3, and CD68 in tumor cells and/or tumor infiltrating lymphocytes were immunohistochemically examined. The associations between protein expressions and overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) were statistically analyzed. RESULTS Patients with positive PD-L1 in tumor cells showed significantly worse OS (Log-rank test: HR 5.146, p = 0.001, Cox regression analysis: HR 4.331, p = 0.014) and PFS (Log-rank test: HR 3.31. p = 0.022), along with significantly lower DCR (14.3%) compared to the PD-L1 negative patients (67.5%). In addition, patients with strong expression of Nectin-4 in tumor cells showed significantly higher DCR (100%) than the other patients (50%). CONCLUSION PD-L1 expression in tumor cells was associated with poor prognosis (OS and PFS) and low DCR. Interestingly, the strong expression of Nectin-4 was correlated with high DCR. PD-L1 and Nectin-4 expression in tumor cells could be prognostic biomarkers useful for pembrolizumab in patients with advanced UC.

Abstract
BACKGROUND Recent studies have revealed that atrial fibrillation (AF) patients have a high risk of developing cognitive impairment, vascular dementia, and Alzheimer's disease (AD). Some reports suggest that the application of oral anticoagulant with an appropriate dose may have a preventive effect on AD. However, which oral anticoagulant drug is more appropriate for preventing AD and the underlying mechanism(s) is still unknown. OBJECTIVE The aim of the present study was to assess the treatment effect of rivaroxaban administration as well as investigate the roles of PAR-1 and PAR-2 in the AD + CAA mice model. METHODS In the present study, we compared a traditional oral anticoagulant, warfarin, and a direct oral anticoagulant (DOAC), rivaroxaban, via long-term administration to an AD with cerebral amyloid angiopathy (CAA) mice model. RESULTS Rivaroxaban treatment attenuated neuroinflammation, blood-brain barrier dysfunction, memory deficits, and amyloid-β deposition through PAR-1/PAR-2 inhibition in the AD + CAA mice model compared with warfarin and no-treatment groups. CONCLUSION The present study demonstrates that rivaroxaban can attenuate AD progress and can be a potential choice to prevent AD.

Abstract
Abstract
Background
Fractional flow reserve (FFR) is a gold standard method to evaluate functional lesion severity in daily clinical practice. Recently, the resting full-cycle ratio (RFR) was Previous studies showed the better diagnostic performance of RFR comparing with FFR. It is well known that patients with chronic kidney disease (CKD) have poor prognosis. Therefore, we should carefully assess the functional lesion severity in CKD patients. However, it is unclear whether the diagnostic performance of RFR for detecting functional ischemia is similar regardless of the degree of renal function. The aim of this study is to compare the diagnostic performance of RFR based on renal function.
Method
This study was a prospectively enrolled observational study. A total of 265 consecutive patients with 373 intermediate lesions were enrolled in this study. There were classified into three groups according to renal function (Group 1: eGFR ≥60 mL/min/1.73m2; Group 2: 30 mL/min/1.73m2 ≤eGFR <60 mL/min/1.73m2; Group 3: eGFR <30mL/min/1.73m2). The RFR was measured after adequately waiting for stable condition, while FFR was measured after intravenous administration of ATP (180mcg/kg/min). The discordance between FFR and RFR were assessed the data using known cutoffs for FFR (≤0.80) and RFR (≤0.89).
Results
Of 373 lesions, the median age was 70.1±11.0 years. Functional significance was observed in 153 lesions (41.0%) of all lesions. RFR showed a significant correlation with FFR in each group (Group 1; r2=0.63 [p<0.001], Group 2: r2=0.67 [p<0.001], Group 3: r2=0.51 [p<0.001], respectively). The ROC curve analysis of RFR showed differential results for predicting functional significance (Group 1: AUC 0.88, cut-off value 0.91; Group 2: AUC 0.88, cut-off value 0.89; Group 3: AUC 0.81, cut-off value 0.83; respectively) in each group. The prevalence of discordant between RFR and FFR was significantly different among 3 groups (Group 1: 16.5%, Group 2: 19.4%, Group 3: 25.0%, respectively, p<0.05 for among 3 groups).
Conclusion
The diagnostic performance of RFR was different based on renal function. During RFR acquisition, the degree of renal function could influence concordance with FFR, and should be taken into account when interpreting RFR.

Abstract
Abstract
Background
Diameter, intima–media thickness (IMT), and flow parameters, including resistance index (RI) and pulsatility index (PI), in the common carotid artery (CCA) are markers of arterial remodeling, atherosclerosis, and vascular resistance, respectively. These CCA parameters have usually been evaluated as markers of target organ damage. Little is known about whether these parameters predict a new onset of hypertension.
Purpose
In this study, we investigated the association of CCA parameters including IMT, diameter, RI, and PI with the incidence of hypertension.
Methods
This is an observational study involving 1249 participants (656 women, mean age 69.6 years) without hypertension, who underwent carotid artery ultrasonography at baseline. The participants were divided into elderly group (defined as age ≥70 years) and a middle-aged group. We defined obesity as BMI ≥25 kg/m2. CCA diameter was defined as the distance between the adventitia–media interface on the near wall and the media–adventitia interface on the far wall. IMT was defined as the distance between the lumen–intima and media–adventitia interfaces. RI was calculated as [peak systolic velocity (PSV)- end-diastolic velocity (EDV)]/PSV. PI was calculated as (PSV-EDV)/Vmean. Larger CCA diameter, increased IMT, high RI, and high PI were determined based on the optimal cutoff values from ROC curve analysis.
Results
Over a mean 5.1-year follow-up period, 524 participants developed hypertension. Multivariate logistic regression analyses showed that larger CCA diameter and increased IMT were significant predicators for incident hypertension in elderly group, but not in middle-aged group. High RI, and high PI were significant predicators for incident hypertension in both the two groups. CCA diameter, IMT, and RI predicted the incidence of hypertension only in nonobesity group, whereas PI predicted it in both obesity and nonobesity groups (Table).
Conclusion
CCA parameters assessed by ultrasonography are useful markers to estimate the risk of hypertension. In particular, PI is a better predictor for the incidence of hypertension.

Abstract
Abstract
Background
Insulin resistance in adipose tissue attenuates the suppression of lipolysis, leading to increased free fatty acid (FFA) release. The excess FFA may be involved in the development of type 2 diabetes.
Purpose
In this study, we investigated the association of adipose tissue insulin resistance and serum free fatty acid levels with the incidence of type 2 diabetes.
Methods
This is an observational study involving 6800 participants (3451 women, mean age 69.2 years) without diabetes who underwent 75-g oral glucose tolerance test (OGTT) at baseline. The participants were divided into the obesity and nonobesity groups on the basis of body mass index of ≥25 and <25 kg/m2, respectively. Serum FFA levels were assessed before and 30, 60, and 120 min after glucose ingestion, and the total area under the FFA curve (AUCFFA) was calculated. Adipose tissue insulin resistance was assessed using adipose insulin resistance index (adipo-IR) calculated based on fasting FFA and insulin concentrations. The homeostasis model assessment of insulin resistance (HOMA-IR), and the Matsuda index were evaluated as measures of insulin resistance in the liver and whole-body, respectively. High adipo-IR, high fasting FFA, great AUCFFA high HOMA-IR, and low Matsuda index were determined based on the optimal cutoff values from ROC curve analysis.
Results
Over a mean 5.3-year follow-up period, 485 participants developed type 2 diabetes. Multivariate logistic regression analyses showed that high adipo-IR was a significant predicator for incident type 2 diabetes in the obesity group, but not in nonobesity group. AUCFFA, HOMA-IR, and Matsuda index were significantly associated with incident type 2 diabetes in both the two groups (Table).
Conclusion
Serum FFA levels after glucose loading predict the incidence of type 2 diabetes. Adipose tissue insulin resistance was associated with the risk of type 2 diabetes in individuals with obesity, but not in individuals without obesity.

Abstract
We report a 72-year-old woman with Miller-Fisher syndrome (MFS) with syndrome of inappropriate secretion of antidiuretic hormone (SIADH). She developed diplopia and unsteady gait a week after an upper respiratory infection. Neurologic examination revealed ophthalmoplegia, ataxia, symmetrical weakness, numbness, and areflexia. She underwent intravenous immunoglobulin therapy. Her serum sodium concentration decreased to 119 mEq/L on day 12. She had low plasma osmolarity (254 mosm/kg), high urine osmolarity (457 mosm/kg), and high urine sodium level (73 mEq/L), while the blood level of antidiuretic hormone was normal. Anti-GD1b immunoglobulin G (IgG), -GQ1b IgG, -GT1a IgG, and -Gal-C IgM antibodies were positive. We diagnosed her with MFS overlapping with SIADH. Four weeks after onset, her symptoms recovered. The elevation of anti-GD1b, -GQ1b, and -GT1a antibodies that recognize disialosyl residue may be pathologically related to SIADH.

Abstract
Background: Because dementia is an emerging problem in the world, biochemical markers of cerebrospinal fluid (CSF) and radio-isotopic analyses are helpful for diagnosing Alzheimer’s disease (AD). Although blood sample is more feasible and plausible than CSF or radiological biomarkers for screening potential AD, measurements of serum amyloid- β (Aβ), plasma tau, and serum antibodies for Aβ1 - 42 are not yet well established. Objective: We aimed to identify a new serum biomarker to detect mild cognitive impairment (MCI) and AD in comparison to cognitively healthy control by a new peptidome technology. Methods: With only 1.5μl of serum, we examined a new target plate “BLOTCHIP®” plus a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF/MS) to discriminate control (n = 100), MCI (n = 60), and AD (n = 99). In some subjects, cognitive Mini-Mental State Examination (MMSE) were compared to positron emission tomography (PET) with Pittsburgh compound B (PiB) and the serum probability of dementia (SPD). The mother proteins of candidate serum peptides were examined in autopsied AD brains. Results: Apart from Aβ or tau, the present study discovered a new diagnostic 4-peptides-set biomarker for discriminating control, MCI, and AD with 87% of sensitivity and 65% of specificity between control and AD (***p < 0.001). MMSE score was well correlated to brain Aβ deposition and to SPD of AD. The mother proteins of the four peptides were upregulated for coagulation, complement, and plasticity (three proteins), and was downregulated for anti-inflammation (one protein) in AD brains. Conclusion: The present serum biomarker set provides a new, rapid, non-invasive, highly quantitative and low-cost clinical application for dementia screening, and also suggests an alternative pathomechanism of AD for neuroinflammation and neurovascular unit damage.

Abstract
We report 2 cases of probable neuro-Behçet's disease (NBD) with longitudinally extensive transverse myelitis (LETM). In both cases, the patients presented paraplegia, as well as sensory, bladder, and rectal disturbances. Magnetic resonance imaging (MRI) of patient 1 showed continuous high signal intensity extending from the midbrain to the entire spinal cord in the central part of the cord on T2-weighted imaging (T2WI). Spinal MRI of patient 2 revealed high signal intensity extending from Th2 to Th10 in the central part of the cord on T2WI. Both patients received high-dose methylprednisolone. A continuous lesion from the midbrain to the entire spinal cord as in patient 1 has not been previously reported. Patient 2 dramatically improved by infliximab therapy. The present cases suggest that NBD should be considered as a differential diagnosis in patients with LETM.

Abstract
Oxidative stress is part of the entire pathological process that underlies the development of Alzheimer's disease (AD), including the mild cognitive impairment (MCI) stage. Twendee X (TwX) is a supplement containing a strong antioxidative mix of eight antioxidants, which has been shown to have a clinical and therapeutic benefit in AD model mice. Here, we conducted a multicenter, randomized, double-blind, and placebo-controlled prospective interventional study to evaluate the efficacy of TwX in mitigating MCI. The primary outcomes were differences in Mini-Mental State Examination (MMSE) and Hasegawa Dementia Scale-revised (HDS-R) scores between baseline and six months for placebo and TwX groups. Seventy-eight subjects with MCI were randomized into placebo (n = 37) and TwX (n = 41) groups. MMSE scores at six months differed significantly between the TwX and placebo groups (p = 0.018), and HDS-R scores for the TwX group exhibited a significant improvement at six months relative to baseline (p = 0.025). The TwX group did not show any change in affective or activities of daily living scores at six months. The present study indicates that strong antioxidative supplement TwX is clinical beneficial for cognitive function in subjects with MCI.

Abstract
Abstract
Background
Triglyceride deposit cardiomyovasculopathy (TGCV) is a novel cardiovascular disorder, encoded as orphan disease in Europe in 2019, characterized by excessive accumulation of triglyceride in vascular smooth muscle cells, leading to coronary artery disease (CAD). However, there is no data about impact of TGCV on vascular failure after coronary stent implantation.
Purpose
To assess impact of TGCV on the outcome following coronary stent implantation in CAD patients with diabetes mellitus (DM) as Study 1, and chronic hemodialysis as Study 2.
Methods
This is multicenter retrospective estimation consisting of two studies.
Study 1) Among 526 consecutive patients suspected of having CAD who underwent coronary angiography (CAG) and iodine-123-β-methyliodophenyl-pentadecanoic acid (BMIPP) scintigraphy, a tracer for the diagnosis of TGCV, data from 81 patients with DM were analyzed.
The patients were divided into two groups; TGCV (n=7) or non-TGCV (n=74). All patients were implanted with a second-generation DES and underwent follow-up CAG. Binary restenosis (ISR), defined as angiographic luminal diameter >50% by quantitative coronary angiography, in-stent late loss were assessed in 15 stents of TGCV patients and 111 stents of non-TGCV patients.
Study 2) Similarly, among 88 chronic hemodialysis patients, ISR and in-stent late loss were assessed in 12 stents of 9 TGCV patients and 21 stents of 17 non-TGCV patients.
Results
Study 1) There were no significant differences in baseline characteristics between the two groups. In-stent late loss was greater in TGCV group than in non-TGCV group (0.91mm [0.27, 2.39] vs. 0.15mm [0.03, 0.35]; p<0.001), resulting in greater incidence of ISR in TGCV group than in non-TGCV group (46.7% vs. 9.0%; p<0.001). Multivariable logistic analysis revealed TGCV to be an independent predictor for vascular failure after DES implantation in patients with DM.
Study 2) Similarly, in-stent late loss and incidence of ISR were greater in TGCV group than in non-TGCV group (1.20±0.99mm vs. 0.50±0.70, p=0.02; 58.3% vs. 9.5%, p=0.002, respectively). TGCV was an independent predictor for vascular failure after DES implantation in chronic hemodialysis patients.
Conclusion
Apart from existing risk factors such as DM and hemodialysis, TGCV could contribute to a novel risk factor for vascular failure, even in the second-generation DES era.

Abstract
Abstract
Background
Recently, wire-based resting indices have been recognized as gold standard for evaluating physiological lesion assessment. The resting full-cycle ratio (RFR) is a unique resting index which is calculated as the point of absolutely lowest distal pressure to aortic pressure during entire cardiac cycle. It is unclear whether the diagnostic performance of RFR for detecting functional coronary artery stenosis is similar in each coronary artery. The aim of this study is to compare the diagnostic performance of RFR based on target coronary vessel.
Method
This study was a prospectively enrolled observational study. A total of 156 consecutive patients with 220 intermediate lesions were enrolled in this study. The RFR was measured after adequately waiting for stable condition, while FFR was measured after intravenous administration of ATP (180mcg/kg/min). Lesions with FFR ≤0.80 were considered functionally significant coronary artery stenosis.
Results
In all lesions, reference diameter, diameter stenosis, lesion length, RFR, and FFR were 3.0±0.7mm, 45±13%, 13.0±8.8mm, 0.90±0.09, and 0.82±0.10, respectively. Functional significance was observed in 88 lesions (40%) of all lesions. RFR showed a significant correlation with FFR in overall lesions (r=0.774, p<0.001). The ROC curve analysis of RFR showed good accuracy for predicting functional significance (AUC 0.87, diagnostic accuracy 81%) in all subjects. Regarding each target vessel, there were similar and significant positive correlation between RFR and FFR (LAD; r=0.733, p<0.001, LCX; r=0.771, p<0.001, RCA; r=0.769, p<0.001, respectively). The prevalence of discordant between RFR and FFR was significantly different among 3 vessels (LAD 26%, LCX 12%, RCA 13%, respectively, p<0.05 for among 3 groups). Regarding the comparison of ROC curves according to lesion location, AUC was significantly lower in LAD than in LCX and RCA (LAD 0.780, LCX 0.947, RCA 0.926, p<0.01 for LAD compared to LCX, p<0.01 for LAD compared to RCA, respectively). Furthermore, the diagnostic accuracy was significantly different according to target vessel (LAD 74%, LCX 88%, RCA 87%, respectively, p<0.05 for among 3 vessels).
Conclusion
RFR demonstrated better diagnostic accuracy for evaluating functional lesion severity. The diagnostic performance of RFR was different based on target vessel. RFR is a unique and useful resting index, and it may detect functionally significant coronary stenosis that cannot be detected with other resting indices in daily practice.

Abstract
Abstract
Background
Recently, post pulmonary embolism (PE) syndrome or chronic thromboembolic disease after acute PE, has been recognized as important long-term complications. Furthermore, patients may develop with chronic thromboembolic pulmonary hypertension.
Purpose
We aimed to evaluate the frequency of residual pulmonary thromboemboli after acute PE by using our “higher”-resolution CT scan imaging method to detect residual thromboemboli down to sub-segmental pulmonary arteries.
Methods
This study was a prospective multi-center observational study. We enrolled consecutive 34 patients with acute symptomatic PE whose informed consent was obtained, and followed up for one year. One year after the onset of acute PE, patients were referred to our hospital and multiple examination including CT scan, 6-minute walk test (6MWT), questionnaire of SF-36, echocardiography and laboratory testing were performed. Additionally, we have modified the CT obstruction index (CTOI) to quantitatively evaluate the thromboemboli down to sub-segmental pulmonary arteries.
Results
Mean age was 60.5±15.8 years, and 56% were male. No patient was categorized as low recurrent VTE risk which was caused by transient factors, one patient was associated with active cancer, and 12% had known thrombophilia. In 85% of the patients, this onset was the first obvious episode of PE. At diagnosis, elevated B-type natriuretic peptide (BNP) (≥100 pg/ml) or N-terminal (NT)-proBNP (≥500 pg/ml) was observed in 45% of the patients. Median tricuspid regurgitation peak gradient (TRPG) by echocardiography was 30.9 (19.3–50.1) mmHg. Among all, 35% of the patients received single-drug approach with DOACs. At discharge, all of the patients except two were treated with DOACs.
One year after the onset, 21% of the patient were in NYHA II and others were in NYHA I. It was notable that pulmonary thromboemboli was detected by our CT scan in 76% of the patients. Modified CTOI was median 11.9 (1.8–24.4) % as shown in the figure.
In multiple regression analysis, TRPG at diagnosis and BNP at one month were significantly associated with mCTOI (β=0.536, p=0.002 and β=−0.482, p=0.003, respectively). Additionally, lowest SpO2 during 6MWT after one year from the onset, tended to inversely associate with mCTOI (β=−0.341, p=0.052).
Conclusions
Using our modified CT scan imaging method and modified CTOI, residual pulmonary thromboemboli was able to be detected more frequently than the previous studies. Residual pulmonary thromboemboli could be one of the cause of the post PE syndrome and lead to exercise-induced desaturation.

Abstract
Abstract
Background
Venous thromboembolism (VTE) is the third frequent acute cardiovascular syndrome in the Europe and Japan. Since direct oral anticoagulants (DOACs) are widely used now, the morbidity and mortality of pulmonary embolism (PE) patients especially associated with cancer needs to be re-evaluated.
Purpose
We evaluated the clinical course of patients with PE mainly treated with DOACs.
Methods
This retrospective observational study was conducted in a single center. The data were collected from the medical record of consecutive patients who received inpatient treatment of PE. In this study, we have compared PE patients with cancer (cancer PE) to those without cancer (non-cancer PE) and evaluated the mortality, recurrent of VTE and major bleedings.
Results
In total, 140 patients were enrolled: 94 patients were cancer-related, and 46 patients were without cancer (Table). The type of the tumor in cancer PE patients were as follows: gastric 8 (9%), esophageal 5 (5%), pancreatic 12 (13%), lung 14 (15%), lymphoma 2 (2%), gynecologic 17 (18%), renal 2 (2%), bile duct 8 (9%), colon 12 (13%), and others 17 (18%).
Kaplan-Meier curve showed that the cumulative all-cause mortality was significantly higher in the cancer PE group (35/94 (37%) vs. 2/46 (4%), P<0.001 (log rank), HR 10.3 [95% CI:2.5–43.3]). The cumulative incidence of recurrent VTE was significantly higher in the cancer PE group (7/94 (7%) vs. 0/46, P=0.03 (log rank)). There was no significant difference in the cumulative incidence of major bleeding between the cancer PE group and the non-cancer PE group (8/94 (9%) vs. 5/46 (11%)).
Conclusions
The risk of recurrent VTE was still higher in cancer PE patients compared to non-cancer PE patients, although DOACs were used. Meanwhile the incidence of major bleeding was comparable in both groups, the risk of bleeding might be acceptable with using DOACs especially in cancer PE patients.

Abstract
Abstract
Introduction
Fractional flow reserve (FFR) is a gold standard method to evaluate functional lesion severity in daily clinical practice. Recently, the resting full-cycle ratio (RFR) which was newly developed resting indices was launched. Unlike other resting indices evaluated in diastolic phase, RFR is evaluated during entire cardiac phase. Previous studies showed discordance predictors between FFR and instantaneous wave-free ratio. However, it is previously unreported what predictor cause discordant outcome between FFR and RFR.
Purpose
The purpose of this study was to evaluate clinical predictors of discordance between FFR and RFR.
Methods
A total of 156 patients with 220 lesions were prospectively enrolled in this study. RFR was evaluated before inducing hyperemia. FFR was measured after intravenous adenosine triphosphate administration (180 mcg/kg/min). According to FFR and RFR values, the patients and lesions were classified into 4 groups: Concordant negative (Group-1 [n=114]: FFR >0.80, RFR >0.89); negative FFR and positive RFR (Group-2 [n=18]: FFR >0.80, RFR ≤0.89); positive FFR and negative RFR (Group-3 [n=25]: FFR ≤0.80, RFR >0.89); Concordant positive (Group-4 [n=63]: FFR ≤0.80, RFR ≤0.89). Among them, discordance predictors with clinical characteristics between RFR and FFR were compared using by two separate logistic regression analyses. (Group-1 vs. Group-2, Group-3 vs. Group-4, respectively). Age, sex and those predictors with a p value ≤0.10 were included in a multivariate regression analysis using by forward stepwise selection to identify independent predictors of discordance.
Results
On multiple regression analysis, hemodialysis (HD) (OR:6.072 [1.090–33.836]), peripheral artery disease (PAD) (OR:9.053 [1.776–46.162]) and left anterior descending artery (LAD) (OR:9.264 [2.092–41.031]) were significantly associated with positive RFR among negative FFR groups (Groupe 2 discordance). Conversely, diabetes mellitus (DM) (OR:0.212 [0.062–0.721]) and Hb (OR:1.480 [1.102–1.987]) were significantly associated with negative RFR among positive FFR groups (Groupe 3 discordance)
Conclusions
Since the clinical characteristics with HD, PAD, LAD, DM and Hb may influence concordant with FFR during RFR evaluation, it should be considered when interpreting RFR.

Abstract
Abstract
Background
Recently, non-hyperemic physiologic indices have become widespread for evaluating physiological lesion assessment. The resting full-cycle ratio (RFR) is a unique non-hyperemic index which is calculated as the point of absolutely lowest distal pressure to aortic pressure during entire cardiac cycle. It is unclear whether RFR may detect functionally significant coronary stenosis that cannot be detected with other resting indices due to differences in the cardiac cycle. The aim of this study is to compare the diagnostic performance of RFR based on cardiac cycle.
Method
This study was a prospectively enrolled observational study. A total of 156 consecutive patients with 220 intermediate lesions were enrolled in this study. The RFR was measured after adequately waiting for stable condition, while FFR was measured after intravenous administration of ATP (180mcg/kg/min). Lesions with FFR ≤0.80 were considered functionally significant coronary artery stenosis.
Results
In all lesions, reference diameter, diameter stenosis, lesion length, RFR, and FFR were 3.0±0.7mm, 45±13%, 13.0±8.8mm, 0.90±0.09, and 0.82±0.10, respectively. Functional significance was observed in 88 lesions (40%) of all lesions. RFR systole was observed in 24 lesions (10.9%). Regarding to the coronary lesions, RFR systole was more frequent in non-LAD (LAD; 4.2%, left circumflex artery (LCX); 9.8%, and right coronary artery (RCA); 30.4%, respectively, p<0.018). RFR showed a significant correlation with FFR in both systole and diastole (R = 0.918, p<0.001, R = 0.733, p<0.001, respectively). The ROC curve analysis showed similar agreement in both systole and diastole (AUC: 0.881, p<0.001, AUC: 0.864, p<0.001, respectively). RFR provided a good diagnostic accuracy and no difference in both systole and diastole (79.6% and 87.5%, respectively, p=0.58).
Conclusion
RFR is feasible and reliable non-hyperemic index regardless of the difference of cardiac cycle to evaluate physiological lesion severity in daily practice.

Abstract
Alzheimer's disease (AD) and chronic cerebral hypoperfusion (CCH) often coexist in dementia patients in aging societies. The hallmarks of AD including amyloid-β (Aβ)/phosphorylated tau (pTau) and pathology-related events such as neural oxidative stress and neuroinflammation play critical roles in pathogenesis of AD with CCH. A large number of lessons from failures of drugs targeting a single target or pathway on this so complicated disease indicate that disease-modifying therapies targeting multiple key pathways hold potent potential in therapy of the disease. In the present study, we used a novel mouse model of AD with CCH to investigate a potential therapeutic effect of a free radical scavenger, Edaravone (EDA) on AD with CCH via examining motor and cognitive capacity, AD hallmarks, neural oxidative stress, and neuroinflammation. Compared with AD with CCH mice at 12 months of age, EDA significantly improved motor and cognitive deficits, attenuated neuronal loss, reduced Aβ/pTau accumulation, and alleviated neural oxidative stress and neuroinflammation. These findings suggest that EDA possesses clinical and pathological benefits for AD with CCH in the present mouse model and has a potential as a therapeutic agent for AD with CCH via targeting multiple key pathways of the disease pathogenesis.

Abstract
BACKGROUND The free radical scavenger edaravone is a proven neuroprotective drug for patients with amyotrophic lateral sclerosis (ALS). Our objective was to evaluate the therapeutic effects of edaravone for oxidative stress and anti-oxidative activity in ALS patients. METHODS Twenty-two ALS patients with a disease duration of 2 years, treated by edaravone, and 25 control participants were evaluated according to their clinical scores, including ALS functional rating scale-revised (ALSFRS-R), and serum and cerebrospinal fluid (CSF) markers of oxidative stress dROM and anti-oxidative activity OXY. RESULTS Serum and CSF markers of anti-oxidative activity OXY were significantly decreased in ALS patients at pre-treatment compared with controls (##p < .01), which was improved in the course of edaravone treatment. Both serum and CSF OXY were significantly correlated with ALS clinical scores including ALSFRS-R (*p < .05, **p < .01, ***p < .001). Furthermore, serum OXY at pre-treatment was significantly correlated with a change in the ALSFRS-R score in the sixth cycle of edaravone treatment (*p < .05). CONCLUSIONS The present study suggests significant correlations between anti-oxidative activity and ALS clinical severity, and the therapeutic efficacy of edaravone for decreased anti-oxidative activity in ALS.

Abstract
The incidence of systemic amyloid A (AA) amyloidosis was high in Bengalese finches
(Lonchura striata var. domestica), as 150 of 235 birds from 5 breeding
colonies (63.8%) tested positive for it. The incidence was statistically significantly
higher in one colony. The liver was the most frequently affected organ (150 cases),
followed by the spleen and then the kidneys. The degree of amyloid deposition was high in
the liver and spleen and low in the kidneys. The histological distribution of amyloid
deposits was similar in all finch species. Species-specific or colony-specific
predisposing factors for systemic AA amyloidosis in Bengalese finches remain to be
elucidated. As far as we know, this is the first report of amyloidosis in Bengalese
finches.

Abstract
Cu-diacetyl-bis (N4-methylthiosemicarbazone) (CuATSM) has both anti-oxidative and anti-inflammatory activities, but its therapeutic efficacy for oxidative stress has not been thoroughly investigated in acute ischemic stroke. Here, the present study was designed to assess the efficacies of CuATSM in acute ischemic stroke by comparing with the standard neuroprotective reagent edaravone. Mice were subjected to transient middle cerebral occlusion (tMCAO) for 60 min, and then intravenously administrated with CuATSM (1.5 mg/kg) or edaravone (3 mg/kg) just after the reperfusion, and examined at 1 and 3 d. Compared with the vehicle group, CuATSM treatment decreased infarct volumes and oxidative stress at 3d after tMCAO, which was further enhanced by combined CuATSM + edaravone treatment as compared with single CuATSM group, but not improve neurobehaviors. The present study demonstrated that CuATSM showed strong antioxidative and neuroprotective effects in acute ischemic stroke, which was enhanced by the combination with edaravone.

Abstract
The research in electrochemical reduction of CO2 is shifting towards the discovery of new and novel materials. This study shows a new class of material, that of Ge-S-In chalcogenide glass, to be active for reduction of CO2 in aqueous solutions. Experiments were conducted with bulk and particle form of the material, yielding different product for each structural form. Faradaic efficiency of upto 15% was observed in bulk form for CO production while formic acid with up to 26.1 % faradaic efficiency was measured in powder form. Chalcogenide studies have focused primarily on the photoelectrochemical reduction however these results provide a strong merit for introducing metal in chalcogenide glass structures for electrochemical reduction of CO2. The activity for CO2 reduction and the change in product selectivity reflects that further efforts to improve the glass structures can be undertaken in order to increase the faradaic efficiency and selectivity of the products.

Abstract
BACKGROUND Bone marrow stromal cell (BMSC) transplantation is a promising therapeutic approach for cerebral ischemia, as it elicits multiple neuroprotective effects. However, it remains unclear how BMSC transplantation modulates the ubiquitin-proteasome system (UPS) and autophagy under cerebral ischemia. METHODS In the present study, an intermediate level of cerebral ischemia (30 minutes) was chosen to examine the effect of BMSC transplantation on the molecular switch regulating UPS and autophagy. BMSC or vehicle was stereotactically injected into the penumbra 15 minutes after sham operation or transient middle cerebral artery occlusion (tMCAO). RESULTS Thirty minutes of tMCAO artery occlusion significantly increased TUNEL-, ubiquitin-, and p62-positive cells (which peaked at 72 hours, 2 hours, and 2 hours after reperfusion, respectively) and ratios of both BAG3/BAG1 and LC3-II/LC3-I at 24 hours after reperfusion. However, intracerebral injection of BMSCs significantly reduced infarct volume and numbers of TUNEL- and p62-positive cells, and improved BAG3/BAG1 and LC3-II/LC3-I ratios. In addition, observed increases in ubiquitin-positive cells 2 hours after reperfusion were slightly suppressed by BMSC transplantation. CONCLUSIONS These data suggest a protective role of BMSC transplantation, which drove the molecular switch from autophagy to UPS in a murine model of ischemic stroke.

Abstract
The world is rapidly aging and facing an increase in the number of dementia patients, so it is important to detect the preclinical stage of dementia in such countries. We examined both cognitive and affective functions among cognitively normal control (n = 218), mild cognitive impairment (MCI, n = 146), and Alzheimer's disease (AD, n = 305) subjects using two evaluation tools for behavioral and psychological symptoms of dementia (BPSD) [Abe's BPSD score (ABS) and mild behavioral impairment (MBI)]. BPSD were present in 12.4% (ABS) and 9.6% (MBI) of cognitively normal people, 34.9% and 32.2% in MCI subjects, and 66.2% and 51.1% in AD patients. Both ABS (§p<0.05) and MBI (§§p < 0.01) score showed worse score with cognitive decline of the Mini-Mental State Examination in the AD group in BPSD-positive participants. Similar correlations were found in all participants in AD group (||||p < 0.01 versus ABS and MBI). Among the subscales in BPSD-positive participants, an apathy/indifference score of ABS and a decreased motivation of MBI showed significant differences in AD patients compared to the control and MCI subjects (**p<0.01). In addition, subscale analyses further showed a downward trend from the control to MCI and AD subjects in four ABS subscales and three MBI subscales. The present study showed the preclinical presence of BPSD in cognitively normal people, more so in MCI subjects, and ABS detected BPSD more sensitively than MBI in all three groups.

Abstract
UNLABELLED To elucidate mutation spectrum and genotype-phenotype correlations in Japanese patients with OI, we conducted comprehensive genetic analyses using NGS, as this had not been analyzed comprehensively in this patient population. Most mutations were located on COL1A1 and COL1A2. Glycine substitutions in COL1A1 resulted in the severe phenotype. INTRODUCTION Most cases of osteogenesis imperfecta (OI) are caused by mutations in COL1A1 or COL1A2, which encode α chains of type I collagen. However, mutations in at least 16 other genes also cause OI. The mutation spectrum in Japanese patients with OI has not been comprehensively analyzed, as it is difficult to identify using classical Sanger sequencing. In this study, we aimed to reveal the mutation spectrum and genotype-phenotype correlations in Japanese patients with OI using next-generation sequencing (NGS). METHODS We designed a capture panel for sequencing 15 candidate OI genes and 19 candidate genes that are associated with bone fragility or Wnt signaling. Using NGS, we examined 53 Japanese patients with OI from unrelated families. RESULTS Pathogenic mutations were detected in 43 out of 53 individuals. All mutations were heterozygous. Among the 43 individuals, 40 variants were identified including 15 novel mutations. We found these mutations in COL1A1 (n = 30, 69.8%), COL1A2 (n = 12, 27.9%), and IFITM5 (n = 1, 2.3%). Patients with glycine substitution on COL1A1 had a higher frequency of fractures and were more severely short-statured. Although no significant genotype-phenotype correlation was observed for bone mineral density, the trabecular bone score was significantly lower in patients with glycine substitutions. CONCLUSION We identified pathogenic mutations in 81% of our Japanese patients with OI. Most mutations were located on COL1A1 and COL1A2. This study revealed that glycine substitutions on COL1A1 resulted in the severe phenotype among Japanese patients with OI.

Abstract
Abstract
Background
Triglyceride deposit cardiomyovasculopathy (TGCV) is a novel clinical concept found among Japanese cardiac transplant recipients in 2008 that the abnormal intracellular triglyceride (TG) metabolism results in the ectopic accumulation of TG in vascular smooth muscle cells and cardiomyocytes, leading to diffuse narrowing coronary artery disease (CAD) and heart failure. TGCV is estimated to affect almost forty to fifty-thousand people in Japan, but there is no real-world date about the prevalence or latency.
Purpose
To evaluate TGCV latency in population with CAD, especially requiring urgent coronary angiography as Study 1, and chronic hemodialysis as Study 2.
Methods
This is multicenter retrospective estimation consisting of two studies.
Study 1) From 2012 to 2017, consecutive 400 patients of unstable angina or acute myocardial infarction who underwent urgent coronary angiography (CAG) and following iodine-123-β-methyliodophenyl-pentadecanoic acid (BMIPP) scintigraphy, a tracer for the diagnosis of TGCV, were enrolled.
Study 2) From 2011 to 2017, 88 chronic hemodialysis patients who underwent planed CAG and BMIPP scintigraphy for detection of ischemic heart disease were enrolled.
TGCV was diagnosed based on the latest diagnostic criteria for TGCV. The criteria include two major items (2 points each: BMIPP scintigraphy Wash-Out Rare <10%, Diffuse narrowing coronary arteries) and two minor items (1 point each: Jordans' anomaly in peripheral blood smear, Diabetes). Four points or more and three points indicated definite and probable TGCV, respectively. Only Items other than Jordans' anomaly were available for the diagnosis of TGCV because of retrospective nature. We evaluated the latent rate of definite and probable TGCV.
Results
Study 1) Figure (left) demonstrates the result of Study 1. Definitive TGCV patients were 14 patients, accounting for 3.5% of total 400 patients, and probable TGCV patients were 39 patients, accounting for 9.8% of all. Total 53 definitive and probable TGCV patients accounted for 13.3% of all. Annual average latency were 3.6±1.7% as definitive, 10.0±5.5% as probable and 13.6±6.6% as definitive and probable TGCV, respectively.
Study 2) Figure (right) demonstrates the result of Study 2. Definitive TGCV patients were 17 patients, accounting for 19.3% of total 88 hemodialysis patients, and probable TGCV patients were 22 patients, accounting for 25.0% of all. Total 39 definitive and probable TGCV patients accounted for 44.3% of all. Annual average latency of definitive TGCV was 19.3±13.4%. Of the 17 definitive TGCV patients, 9 patients were hemodialysis patients with diabetes.
Figure 1
Conclusions
TGCV might be latent with a probability of 3.6±1.7% per year in patients with unstable angina or acute myocardial infarction, and with a probability of 19.3±13.4% per year in chronic hemodialysis patients suspected of ischemic heart disease.

Abstract
Abstract
Background
Triglyceride deposit cardiomyovasculopathy (TGCV) is a novel disease concept characterized by the excessive accumulation of triglyceride in cardiomyocytes and vascular smooth muscle cells, leading to coronary artery disease (CAD), heart failure, and arrhythmia. However, it is rarely known whether TGCV contributes to the increased risk of vascular failure after drug eluting stent (DES) implantation.
Purpose
The aim of this study was to evaluate vascular failure after 2nd generation DES implantation in patients with TGCV.
Methods
Among 637 consecutive patients suspected of having CAD who underwent both coronary angiography and iodine-123-β-methyliodophenyl-pentadecanoic acid (BMIPP) scintigraphy between 2010 and 2018, we analyzed the data from 92 patients who met the inclusion criteria (shown in Table and Figure). Ninety-two patients were allocated to the presence (TGCV group, 11 patients) or absence (control group, 81 patients) of TGCV. All of 92 patients were implanted 2nd generation DES and underwent planned follow up coronary angiography. Control patients were diagnosed of diabetes mellitus. Binary restenosis (ISR), defined as angiographic luminal diameter ≥50% by quantitative coronary angiography, target lesion revascularization (TLR), In-stent late loss and restenosis morphology were assessed in 23 stents of TGCV group and 120 stents of control group.
Results
There were no significant differences in baseline characteristics between the two groups except for the prevalence of hypertension. In-stent late loss was greater in TGCV than in control (0.45 (−0.04 to 3.33) vs. 0.15 (−0.18 to 2.75), p=0.ehz748.10067), resulting in greater incidence of ISR and TLR in TGCV than in control (34.8% vs. 10.0%, p=0.0017; 21.7% vs. 6.7%, p=0.021, respectively). On multivariable logistic regression analysis, TGCV was found to be a significant and independent predictor for ISR after 2nd generation DES implantation. Regarding restenosis morphology, diffuse and occlusive pattern of ISR, were more frequently observed in TGCV than control (87.5% and 33.3%, Fisher's exact test p=0.028).
Table 1.The 4th edition diagnostic criteria for TGCV Items Clinical findings 2 points I) BMIPP scintigraphy Wash-Out Rare <10% II) Diffuse narrowng coronary arteries 1 point III) Jordans anomaly in peripheral blood smear IV) Diabetes Decision 4 points or more → Definite TGCV
Figure 1
Conclusion
Patients with TGCV showed the greater incidence of vascular failure even after 2nd generation DES implantation, contributing to the novel risk factor for coronary intervention even in the 2nd DES era.

Abstract
Abstract
Background
Although fractional flow reserve (FFR) is a gold standard method to evaluate functional lesion severity in the catheterization laboratory, the need of hyperemic condition limits the widespread adoption of FFR. Recently, the resting full-cycle ratio (RFR) which was newly developed resting indices was launched. It is unclear whether RFR as resting condition could assess physiological lesion severity of coronary artery stenosis. The aim of this study was to evaluate the diagnostic impact of RFR compared to FFR in entire range of coronary artery stenosis.
Method
A total of 53 patients with 70 lesions were enrolled in this study. The RFR was measured after adequately waiting for stable condition, while FFR was measured after intravenous administration of ATP (180mcg/kg/min). Lesions with FFR ≤0.80 were considered functionally significant coronary artery stenosis.
Results
In all lesions, reference diameter, diameter stenosis, lesion length, RFR, and FFR were 3.3±0.8mm, 44±12%, 14.6±7.2mm, 0.90±0.11, and 0.83±0.11, respectively. Functional significance was observed in 24 lesions (34%) of all lesions. The RFR showed a significant correlation with FFR (y = 0.800x + 0.239, R = 0.817, p<0.001). The Bland-Altman plot demonstrated a good agreement with a mean difference of 0.07 and a standard deviation of 0.06 between RFR and FFR across entire range of coronary artery stenosis. ROC curve analysis showed an excellent accuracy of RFR cut-off of ≤0.90 in predicting FFR ≤0.80 which had 78% sensitivity and 87% specificity (AUC 0.87, diagnostic accuracy 84%).
Conclusion
The RFR as newly resting indices is reliable to the assessment of functional lesion severity. This physiology-based approach may be a possible alternative method for FFR measurements in daily practice.
