Abstract
Background: Contrast-induced nephropathy (CIN) is clinically important because of its poor prognosis. The incidence of CIN is higher in emergency than elective percutaneous coronary intervention (PCI) because there is no established method to prevent CIN. The aim of this study is to evaluate whether bolus administration of a concentrated solution of sodium bicarbonate can prevent CIN in patients undergoing emergency PCI. Methods and Results: This multicenter prospective single-arm trial with historical controls will include patients who are aged ≥20 years and will undergo cardiac catheterization for suspected acute myocardial infarction (AMI). Patients will receive an intravenous bolus administration of concentrated sodium bicarbonate solution (7% or 8.4%, 20 mEq) and will be observed for 72±12 h. Data for the control group, comprising all patients who underwent PCI for AMI between January 1, 2020 and December 31, 2020 across participating hospitals, will be extracted. The primary endpoint is the incidence of CIN, defined as an increase in serum creatinine of >0.5 mg/dL or >25% from baseline within 48±12 h. We will evaluate the endpoints in the prospective group and compare them with those in the historical control group. Conclusions: This study will evaluate whether a single bolus administration of concentrated sodium bicarbonate can prevent CIN after emergency PCI.

Abstract
Introduction Radiation and intra-arterial cisplatin infusion chemotherapy (RADPLAT) for advanced maxillary sinus cancer has accumulated evidence as a treatment with fewer complications and better 5-year survival rates. In this study, we report a case in which pterygoid muscle necrosis occurred 6 months following RADPLAT treatment for maxillary sinus cancer. Case Presentation The 45-year-old woman had a long history of taking immunosuppressants against rheumatoid arthritis (RA) prior to treatment. Although achieving complete response (CR) to RADPLAT, the patient developed trismus (1 fingerbreadth or less) 6 months following treatment. Abscess formation and recurrence were suspected from the imaging findings; however, the biopsy with endoscopy indicated necrotic tissue. Currently, 18 months have passed without cancer recurrence. Although trismus temporarily improved with rehabilitation, the width of the mouth opening is currently a few millimeters, so the patient can only take liquid food. Conclusion Pterygoid muscle necrosis should be recognized as a new major complication.

Abstract
We report a case of a 59-year-old man with human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome (AIDS) who developed multiple small-vessel strokes during the immune reconstitution phase. The patient had been diagnosed with HIV/AIDS with a low CD4 count and high viral load and started combinational antiretroviral therapy (cART) with raltegravir, emtricitabine, and tenofovir alafenamide fumarate seven months before the admission. He was admitted to our hospital with complaints of mild dysarthria and left-sided hemiparesis, but lacking consciousness/cognitive disturbances. Diffusion-weighted images (DWI) revealed multiple areas of hyperintensity in the anterior circulation system of the brain. Because we identified decreased activity of protein S through extensive examinations, we treated him initially with intravenous infusion of heparin sodium and aspirin; however, DWI detected multiple progressive small-vessel strokes after that. We considered that the immune reconstitution accounted for the small-vessel vasculopathy/vasculitis, leading to ischemic stroke. Therefore, we initiated oral administration of prednisolone, which successfully prevented stroke recurrence. This report describes a case of multiple small-vessel strokes following cART for AIDS during the immune reconstitution phase, effectively treated with steroids, which may often go undiagnosed due to their relatively mild symptoms.

Abstract
Background
Although regular physical activity has beneficial cardiovascular effects, exercise can trigger sudden cardiac arrest (SCA). Coronary artery disease (CAD) was identified as the most common cause of an exercise-related out-of-hospital cardiac arrest (OHCA). Regular exercise has been reported to reduce the risk of plaque rupture in animal studies and basic research. Therefore, we compared the coronary artery findings in CAD-OHCA patients with and without habitual exercise.
There have been few reports on whether regular exercise changes the prognosis in OHCA due to CAD (CAD-OHCA). We investigated the association between the better clinical outcome and the regular exercise in patients with CAD-OHCA.
Methods
This is a single-center retrospective analysis from 2006 to 2019. The consecutive 397 patients with OHCA due to myocardial ischemia underwent coronary angiography (CAG). After excluding 73 patients with vasospastic angina, the remaining 324 patients with CAD were enrolled in this study. We divided these patients into two groups according to whether they were habitually exercising (Exercise group: N=37) or not/unknown (Non-Exercise group: N=287).
Clinical outcome was a 30-day survival with minimal neurologic impairment represented by a Glasgow-Pittsburgh Cerebral Performance Categories Scale value 1 or 2.
Results
The patients in the Exercise Group were significantly younger (exercise vs. non-exercise, 57±12 vs. 64±12 years; P<0.01) than those in the non-exercise group. The Exercise group had a lower incidence of diabetes mellitus (22% vs. 42%; P=0.02) and a higher incidence of dyslipidemia (81% vs. 62%; P=0.02) than the non-exercise group. The time from collapse to cardiopulmonary resuscitation (1.4±4.0 vs. 3.0±4.8min) and from collapse to return of spontaneous circulation (11.9±10.0 vs. 28.0±25.3min) were shorter in Exercise group (all p<0.05). The ST-segment elevation was recorded on electrocardiography in fewer of the Exercise group (22% vs. 63%; P<0.01). The finding of culprit lesion in the coronary arteries on arrival resulted significant differences between the 2groups (good collateral and/or TIMI3 flow: 62% vs. 25%, the plaque rupture and/or thrombus: 22% vs. 73%) (all p<0.01) (Figure 1). Kaplan-Meier curve showed Exercise group has better neurological outcome at 30days compared than Non-Exercise (95% vs 51%; P<0.001, log-rank test) (Figure 2). Multivariable Cox proportional hazards models revealed that a habitual exercise was one of the predictors of a good neurological outcome (HR 0.21, 95% CI 0.05–0.92; P=0.039).
Conclusions
The patients with habitual exercise had less plaque rupture, less coronary thrombosis than non-exercise. The patients with regular exercise had better clinical outcomes than non-exercise after CAD-OHCA.

Abstract
A 19-year-old man with a history of Chiari type I malformation was admitted to our hospital two times within a 2-month period because of bacterial meningitis. Cerebrospinal fluid (CSF) analysis showed neutrophilic pleocytosis and hypoglycorrhachia. During the second admission, we became aware of hearing loss on the right since age 15 years. High-resolution temporal bone CT showed soft tissue opacification of the right epitympanum and external auditory canal. Tissue biopsy resulted in CSF otorrhea and pneumocephalus. CT cisternography revealed a temporal bone CSF leak. Brain MRI showed a dural defect localized to the anterior petrous apex. Using a combined middle cranial fossa-transmastoid approach, the dural defect and associated arachnoid granulations were located along the superior side of the greater petrosal nerve and repaired. A CSF leak without underlying pathology, such as trauma, surgery, or congenital abnormality, is defined as spontaneous. Spontaneous CSF leak should be considered as a cause of recurrent bacterial meningitis even when CSF otorrhea and fluid behind the tympanic membrane are clinically absent.

Abstract
Background This study aimed to collect data on “triple therapy” for heart failure (HF) with angiotensin-converting enzyme inhibitors (or receptor blockers), β-blockers, and mineralocorticoid receptor antagonists in all eight regions of Japan and clarify the reason for the selection of this therapeutic approach. Methods and results We used data from April 2017 to March 2018 from the Medical Data Vision database (380 facilities) to analyze factors impacting triple therapy for HF. Among patients who were hospitalized for HF during the study period, 51,933 patients met the inclusion criteria and underwent further analyses. A reference value of 20.45% from Kanto was used to compare the eight Japanese regions. From the patient cohort, 10,006 (19.27%) patients receiving triple therapy were identified. The highest and lowest rates of triple therapy were in Chugoku (21.90%) and Shikoku (14.27%), respectively, suggesting regional differences in the use of triple therapy at discharge for patients with HF (P < 0.001). Regression analysis revealed a decrease in the administration of triple therapy for patients with chronic kidney disease (odds ratio [OR], 0.45; 95% confidence interval [CI], 0.43–0.48]; P < 0.001), those aged 75 years and older (OR, 0.46, 95% CI: 0.44–0.49; P < 0.001), those from Shikoku (OR, 0.69; 95% CI, 0.60–0.80; P < 0.001), those with chronic obstructive pulmonary disease (OR, 0.75; 95% CI, 0.68–0.84; P < 0.001), those with anemia (OR, 0.78; 95% CI, 0.62–0.98; P = 0.034), and those from Tohoku (OR, 0.83; 95% CI, 0.75–0.92; P < 0.001). Conclusions Future efforts to rectify the regional variance in drug therapy conforming to the guidelines for the treatment of acute and chronic HF will help to extend the healthy lifespans of patients with HF. Further clarification is required to determine instances where triple therapy should be avoided based on patient factors, and appropriate countermeasures should be identified.

Abstract
Background and objectives: Pulmonary vein (PV) reconnection is a major reason for recurrence after catheter ablation of paroxysmal atrial fibrillation (PAF). However, the timing of the recurrence varies between patients, and recurrence >1 year after ablation is not uncommon. We sought to elucidate the characteristics of atrial fibrillation (AF) that recurred in different follow-up periods. Materials and Methods: Study subjects comprised 151 consecutive patients undergoing initial catheter ablation of PAF. Left atrial volume index (LAVi) and atrial/brain natriuretic peptide (ANP/BNP) levels were systematically measured annually over 3 years until AF recurred. Results: Study subjects were classified into four groups: non-recurrence group (n = 84), and short-term- (within 1 year) (n = 30), mid-term- (1–3 years) (n = 26), and long-term-recurrence group (>3 years) (n = 11). The short-term-recurrence group was characterized by a higher prevalence of diabetes mellitus (hazard ratio 2.639 (95% confidence interval, 1.174–5.932), p = 0.019 by the Cox method), frequent AF episodes (≥1/week) before ablation (4.038 (1.545–10.557), p = 0.004), and higher BNP level at baseline (per 10 pg/mL) (1.054 (1.029–1.081), p < 0.0001). The mid-term-recurrence group was associated with higher BNP level (1.163 (1.070–1.265), p = 0.0004), larger LAVi (mL/m2) (1.033 (1.007–1.060), p = 0.013), and longer AF cycle length at baseline (per 10 ms) (1.194 (1.058–1.348), p = 0.004). In the long-term-recurrence group, the ANP and BNP levels were low throughout follow-up, as with those in the non-recurrence group, and AF cycle length was shorter (0.694 (0.522–0.924), p = 0.012) than those in the other recurrence groups. Conclusions: Distinct characteristics of AF were found according to the time to first recurrence after PAF ablation. The presence of secondary factors beyond PV reconnections could be considered as mechanisms for the recurrence of PAF in each follow-up period.

Abstract
Abstract
Background and purpose
Many reports have examined electrocardiographic (ECG) changes after subarachnoid hemorrhage from long ago; however, there are few reports on the prognosis of patients who have an ECG abnormality. Therefore, in this study, the prognoses of patients with subarachnoid hemorrhage showing abnormal ECG findings were retrospectively analyzed.
Methods
Over 30 months from January 2014 to June 2016, 199 patients (mean age, 61.1±17.0 years; 46.7% male) admitted with a subarachnoid hemorrhage (SAH) were enrolled. To assess the mechanism underlying abnormal ECG in the SAH, predictor variables, such as demographics (age, sex, and body surface area), hemodynamics (heart rate and systolic blood pressure), blood biochemical results, neurological assessments (Glasgow Coma Scale), and computed tomography (CT) severity classification (World Federation of Neurosurgical Societies classification) were recorded. The subarachnoid hemorrhage was classified into either the cerebral aneurysm rupture group (N=132) or traumatic subarachnoid hemorrhage group (N=67) and analyzed.
Results
In the cerebral aneurysm rupture group, the QT prolongation was significantly increased compared with the traumatic subarachnoid hemorrhage group (424.8±87.7 ms vs. 400.5±95.8 ms, P<0.05). There was a correlation between consciousness level (Glasgow Coma Scale) on admission and QT prolongation, and significant QT prolongation was observed in critical patients (Pearson's correlation coefficient test P=0.04). ST changes correlated with CT classification severity (WFNS classification), and the most severe group (WFNS Grade 5) showed significant ST changes. On admission, the cerebral aneurysm rupture group and 97.0% in the traumatic subarachnoid hemorrhage group.
Conclusions
Significantly prolonged QT and ST changes are noted in patients with severe aneurysmal subarachnoid hemorrhage. The cause of the ECG abnormality in subarachnoid hemorrhage patients is not yet understood. A small number of experimental animal models have shown that electrocardiogram abnormalities associated with subarachnoid hemorrhage develop in the brain stem, and an autonomic nerve abnormality may also be involved.
A D-dimer is positively correlated with both aneurysm trauma and traumatic subarachnoid hemorrhage and may be used for auxiliary diagnosis of a subarachnoid hemorrhage.

Abstract
Acute coronary syndrome (ACS) is the major cause of out-of-hospital cardiac arrest (OHCA). The relationship between the findings from the study of coronary images and return of spontaneous circulation (ROSC) interval is still unknown. Hence, we investigated this relationship in ACS patients with OHCA.A cohort of 2779 patients was admitted to our emergency center due to cardiopulmonary arrest (CPA) between April 2011 and March 2015. We included ACS patients who had CPA with ventricular fibrillation (VF) as an initial rhythm, were successfully resuscitated, underwent coronary angiography (CAG), had a culprit lesion, and were diagnosed with ACS (n = 58; age, 63.7 ± 12.0 years; 93.1% male).We divided the 58 patients into two groups, an early ROSC group (ROSC ≤ 20 minutes: E-ROSC) and a late ROSC group (ROSC > 20 minutes: L-ROSC), and then analyzed their characteristics.The finding of a collateral artery for the culprit lesion location, Rentrop II-III, and TIMI III flow on CAG on arrival presented no significant differences between the two groups (Rentrop II-III: 25.0% versus 23.5%, P = 0.90; TIMI III: 33.3% versus 35.3%, P = 0.88). The incidence of multivessel coronary artery disease (MVD) was lower in the E-ROSC group than in the L-ROSC group (16.7% versus 58.8%, P = 0.001).Collateral and TIMI flow were not associated with ease of resuscitation, but MVD may have a negative impact on resuscitation, especially in VF patients.

Abstract
BACKGROUND Germ cell tumors arise in the testis, ovary, or extragonadal locations and have a wide range of histopathological and clinical presentations. The relative lack of animal models of germ cell tumors has impeded functional assessment of candidate driver genes. Previously, we described the development of testicular germ cell tumors in zebrafish carrying a mutation in bmpr1bb, a BMP family receptor, and demonstrated that human germ cell tumors have defects in BMP signaling. OBJECTIVE To further credential the zebrafish model for studies of human germ cell tumor, and to elucidate conserved genetic programs underlying the development of germ cell tumor. MATERIALS AND METHODS We used genetic techniques to ablate the germ cell lineage in developing fish and tested tumors for loss-of-heterozygosity of the wild-type allele of bmpr1bb. We performed comparative gene expression profiling of zebrafish and human germ cell tumors and carried out functional studies of selected genes. RESULTS Ablation of germ cells completely prevents testis tumor formation in the fish, definitively establishing the germ cell origin of the tumors. Germ cell tumors in bmpr1bb heterozygous mutants retain the wild-type allele, indicating haploinsufficiency of bmpr1bb as the mechanism of tumor formation. Comparison of RNA-Seq and microarray data from human and zebrafish germ cell tumors revealed a unique overlapping signature shared by the zebrafish tumors with human seminomas, yolk sac tumors, and embryonal carcinomas. The most highly conserved gene set in this cross-species analysis included potential driver genes such as JUP, which we show to be essential for germ cell tumor cell growth. CONCLUSION Our findings highlight the value of cross-species comparative oncology for the identification of candidate human cancer genes.

Abstract
The aim of this study was to investigate the incidence of binary restenosis and its predictors in patients with ostial lesions of the right coronary artery (RCAos) who underwent percutaneous coronary intervention (PCI). RCAos are associated with a high incidence of restenosis, and the implantations of drug-eluting stents for RCAos have not been fully elucidated. The study participants included 75 patients (72.3 ± 9.5 years, 72% men) who underwent PCI for RCAos at our institution between November 2001 and May 2017. The angle between the greater curvature of the aortic wall and the right coronary artery take-off in the diastolic and systolic phases in the left anterior oblique position view was investigated. Clinical outcome was defined as binary restenosis at follow-up coronary angiography. We also evaluated target lesion failure (TLF) defined as a composite of cardiac mortality, target vessel myocardial infarction, and target lesion revascularization (TLR). The incidence of binary restenosis was 48.0% (n = 36) of the entire cohort. The incidence of TLF was 49.3% (n = 37) of the entire cohort, which was mainly driven by TLR (36.0%, n = 27). The area under the curve of the gap-angle ratio [(difference between the maximum and minimum angles)/(minimum angle); GAR] for binary restenosis was 0.73, and the cutoff value was 0.306 (sensitivity 67%, specificity 82%). The patients were divided into two groups: a low-GAR (< 0.306; n = 30) and high-GAR group (> 0.306; n = 45). Binary restenosis was more frequent in the high-GAR group than in the low-GAR group (76.7% vs. 28.9%, p = 0.007). The cumulative rate of TLF was significantly higher in the high-GAR group when compared with the low-GAR group (53.3% vs. 40.0%, p = 0.01), which was mainly driven by TLR (56.7% vs. 22.2%, p = 0.01). High-GAR (> 0.306) [OR 2.66 (1.34-5.31), p = 0.005] and stent under expansion [OR 2.37 (1.10-5.11), p = 0.03] were found to be independent predictors of binary restenosis after adjustment for multiple confounders. Multivariable analysis also revealed that high-GAR (> 0.306) [OR 2.06 (1.02-4.14), p = 0.03] and stent under expansion [OR 2.82 (1.28-6.19), p = 0.01] were independent predictors of TLF. We suggest that GAR (> 0.306) predicts binary restenosis and TLF in patients undergoing PCI for RCAos.

Abstract
Self-assembly of β-diketonate (Htta = thenoyl(trifluoro)acetone) and 4,4′-azopyridine (Azo-py) with neodymium(iii) ions in the presence of methanol resulted in the formation of mononuclear complex [NdIII(TTA)3(MeOH)2]·0.5Azo-py (A) in which two asymmetric units are linked by Azo-py through hydrogen bonding via methanol. A reveals near-infrared emission (NIR) centred at about 895 and 1056 nm, in the 10–370 K temperature range, originating from the two emissive transitions on Nd(iii) from 4F3/2 to 4I9/2 and 4I11/2 levels, respectively. Furthermore, the NIR luminescence intensity of A at room temperature augments two times upon thermal elimination of one coordinated methanol molecule. The thermally activated A exhibits single centre ratiometric thermometer behaviour in a wide temperature range from 10 to 300 K. Moreover, fluorescence properties of A were compared to another mononuclear complex [NdIII(TTA)3(4-OHpy)(H2O)] (B). Assembly A also exhibits field-induced slow magnetic relaxation properties with an energy barrier of ΔE/kB = 19.7(7) K and an attempt time of relaxation, τ0 = 3.7(8) × 10−7 s for fresh sample A, and ΔE/kB = 27.3 K and τ0 = 8.5(0) × 10−8 for assembly A after thermal treatment at 370 K. In this work, we investigated thermally-induced Nd-based one centred ratiometric thermometer which also exhibit single molecule magnetic properties.![]()

Abstract
AIM Possible causes of exercise-related out-of-hospital cardiac arrest (OHCA) in people with coronary artery disease (CAD) include atherosclerotic plaque rupture (PR) and intra-coronary thrombosis, exercise-induced myocardial ischaemia and other triggers. We investigated whether there are differences in the incidence of PR and/or intra-coronary thrombus and in clinical outcome between 'exercise-related' and 'non-exercise-related' OHCA. METHODS 219 consecutive resuscitated patients with CAD diagnosed by emergency coronary angiography (CAG) were enrolled. They were divided into the exercise group (≥6 METs; n = 35) and non-exercise group (<6 METs; n = 184), according to estimated METs immediately before OHCA using 2011 Compendium of Physical Activities. We investigated whether culprit lesions had PR and/or thrombus using CAG and intravascular ultrasound. The clinical outcome was 30-day survival with minimal neurologic impairment. RESULTS Acute PR and/or thrombus occurred in fewer of the exercise group than the non-exercise group (11% vs. 90%; P < 0.001). The exercise group had a higher incidence of favorable neurological outcome (94% vs. 47%; P < 0.001) than the non-exercise group. Multivariable Cox proportional hazards models revealed that exercise immediately before OHCA was one of the predictors of a good neurological outcome (HR, 0.19; P = 0.025). CONCLUSION The incidence of PR and/or thrombosis was lower in the group taking higher levels of exercise, than in the group taking less or no exercise. "Exercise-related" OHCA with CAD has better clinical outcomes than "non-exercise-related" with a greater proportion of witnessed arrests and early return of spontaneous circulation.

Abstract
Severe cases of genu varum represent a major challenge in obtaining normal alignment. We performed inverted V-shaped HTO in a patient with Turner syndrome. Inverted V-shaped HTO can be a useful surgical method to treat severe tibia vara.
Introduction Severe cases of genu varum represent a major challenge in obtaining normal configuration of the proximal tibia and overall limb alignment. Presentation of case We performed inverted V-shaped high tibial osteotomy (HTO) by using a locking plate for recurrent severe bilateral tibia vara in a 15-year-old female patient with Turner syndrome. Preoperative medial proximal tibial angle (MPTA) and standing femorotibial angle (FTA) of the right/left legs were 67°/69° and 197°/203°, respectively. In order to obtain overall neutral alignment, the correction angle in the right/left knees was required to be 23°/32°. Preoperative planning demonstrated that inverted V-shaped HTO could provide sufficient correction angle with large bone stock and wide bony contact. A postoperative full-standing radiograph showed that the mechanical axes passed through the center of right/left knees with 87°/88° of MPTA. Discussion Inverted V-shaped HTO has advantages, as it requires a smaller amount of bone resection and smaller opening gap compared to the closing-wedge and opening-wedge osteotomies. Conclusion Inverted V-shaped HTO can be a useful surgical method to treat severe tibia vara in order to obtain adequate configuration of the proximal tibia and overall limb alignment.

Abstract
BACKGROUND Steroid-eluting pacemaker leads suppress acute rises in pacing threshold by preventing inflammatory processes. However, we occasionally encounter not persistent but transient rise in the atrial capture threshold (TRACT) early after pacemaker implantation. We believe that this phenomenon is underrecognized in clinical practice and may potentially lead to unnecessary reintervention. We aimed to clarify the prevalence, predictors, and possible mechanisms of TRACT. METHODS AND RESULTS We reviewed clinical records from 239 consecutive patients who underwent dual-chamber pacemaker implantation for sick sinus syndrome (SSS) (N = 102) or atrioventricular block (AVB) (N = 137). Atrial capture threshold was measured at implantation and 7 days, 2 months, and 8 months postimplantation. TRACT was defined as a rise in the threshold at day 7 to ≥twice that at implantation, with an absolute value ≥1.0 V/0.4 ms, and full recovery by 8 months into follow-up. TRACT was observed in 15 patients (6%), of whom13 (87%) suffered from SSS but not AVB. Patients with TRACT had greater body mass index (BMI) (25 ± 5 kg/m2 vs 23 ± 4 kg/m2 , P = 0.01), larger left atrium (42 ± 5 mm vs 38 ± 7 mm, P = 0.03), and were more likely to suffer from paroxysmal atrial fibrillation (60% vs 31%, P = 0.02) than those without TRACT. In multivariable logistic regression analysis, BMI and SSS were the independent predictors of TRACT (odds ratio [OR], 1.172; 95% confidence interval [CI], 1.019-1.349; P = 0.03 and OR, 11.53; 95% CI, 2.010-66.21; P = 0.006, respectively). CONCLUSIONS The distinct phenomenon of TRACT was not rare in clinical practice early after dual-chamber pacemaker implantation, and its occurrence was strongly associated with SSS.

Abstract
Background: We investigated the association between initial ST-segment change after return of spontaneous circulation (ROSC) and the incidence of acute coronary lesions in patients with out-of-hospital cardiac arrest (OHCA), and clinical outcomes of patients with OHCA caused by vasospastic angina pectoris (VSA). Methods: Among 2779 OHCA patients in our institution, all patients with ROSC underwent emergent coronary angiography (CAG) except for those with an obvious extra-cardiac cause of OHCA. Initial ST-segment changes after ROSC were reviewed, and 30-day survival and neurological outcome (Cerebral Performance Category) were evaluated. Results: Of the 155 patients, 52 (34%) had ST-segment elevation (STE) and 103 (66%) had non-STE. Significant coronary culprit lesions were present in 81% of patients with STE and in 33% of patients with non-STE ( P<.001). Percutaneous coronary intervention (PCI) was successful in 60 patients (93.8%) and failed in 4 patients (6.2%). Among 155 patients, 74 patients (47.7%) had favorable neurological prognosis, and 104 patients (67.1%) were alive at 30 days. ST-segment analysis showed good positive predictive value (81%) but low negative predictive value (68%) in diagnosing the presence of acute coronary lesions. VSA was found in 5 patients (9.6%) in the STE group and in 12 patients (11.7%) in the non-STE group. Of these 17 patients, 9 (52.9%) had favorable neurological outcome and 14 (82.4%) were alive at 30 days. Conclusion: An acute culprit lesion may be the cause of OHCA even in the absence of STE. In survivors of OHCA with normal coronary arteries, spasm provocation testing should be performed to detect VSA as a cause of the arrest.

Abstract
Recent studies have shown the contribution of genetic determinants to athletes' physical ability. However, despite the fact that cognitive abilities like self-control and stress-tolerance influence athletes' competitive performance, few studies to date have investigated the association between genetic polymorphism, which is linked to cognitive ability and athletic performance. The present study investigated the link between single-nucleotide polymorphisms (SNPs), which are known to exert influences on dopaminergic neural function and competitive performance of swimmers. The results have revealed superior competitive performance in competitive swimmers with Met allele of catechol-O-methyltransferase Val158Met polymorphism than those with Val/Val genotype. The investigated SNPs of DRD2 and DRD3 were not associated with swimmer's competitive performance. This finding indicates that genetic polymorphism linked to cognitive ability influences the athletes' performance.

Abstract
Bernard-Soulier syndrome (BSS) is a rare bleeding disorder of autosomal recessive inheritance characterized by macrothrombocytopenia. We report the case of a 14-year-old girl diagnosed with BSS who is a fourth-generation Brazilian of Japanese descent and has a compound heterozygote mutation as the responsible gene. The compound heterozygosity would have occurred from the global and long-term racial migration that brought about an accidental encounter of two rare mutant alleles of different origins.

Abstract
In this study, we identify signaling network of necrotic cell death induced by transcriptional repression (TRIAD) by α-amanitin (AMA), the selective RNA polymerase II inhibitor, as a model of neurodegenerative cell death. We performed genetic screen of a knockdown (KD) fly library by measuring the ratio of transformation from pupa to larva (PL ratio) under TRIAD, and selected the cell death-promoting genes. Systems biology analysis of the positive genes mapped on protein-protein interaction databases predicted the signaling network of TRIAD and the core pathway including heterogeneous nuclear ribonucleoproteins (hnRNPs) and huntingtin (Htt). RNA sequencing revealed that AMA impaired transcription and RNA splicing of Htt, which is known as an endoplasmic reticulum (ER)-stabilizing molecule. The impairment in RNA splicing and PL ratio was rescued by overexpresion of hnRNP that had been also affected by transcriptional repression. Fly genetics with suppressor or expresser of Htt and hnRNP worsened or ameliorated the decreased PL ratio by AMA, respectively. Collectively, these results suggested involvement of RNA splicing and a regulatory role of the hnRNP-Htt axis in the process of the transcriptional repression-induced necrosis.

Abstract
BACKGROUND Increased levels of uric acid (UA) have been associated with cardiovascular disease. This association is generally stronger in women than men. However, gender differences in the prognostic value of UA in patients with acute coronary syndrome (ACS) are unknown. We investigated gender differences in the relationship between UA level and the prognosis in patients with ACS. METHOD This was an observational analysis of patients with ACS undergoing percutaneous coronary intervention enrolled in the Ibaraki Cardiac Assessment Study (ICAS) registry. We analyzed 1380 patients (330 women, 1050 men) with ACS who had information on UA. We assessed the association between UA and the incidence of major cardiovascular adverse events (MACE), defined as all-cause death, congestive heart failure, reinfarction, and stroke. Patients were divided according to gender-specific UA quartile. RESULTS The mean UA level in women was significantly lower than that in men (4.9mg/dl vs 5.9mg/dl, p<0.001). After a median duration of follow-up period of 437 days (interquartile range 222-801 days), MACE had occurred in 186 (13%) patients [56 (17%) events in women; 130 (12%) events in men]. Kaplan-Meier analysis for MACE-free survival demonstrated that a higher quartile of UA was associated with MACE in both women and men (p<0.001, p=0.002, respectively). Multivariate Cox regression analysis revealed that the highest quartile of UA, as compared with the lowest quartile of UA, was an independent predictor of MACE in women [hazard ratio (HR), 2.84; 95% CI, 1.19-6.77; p=0.018] but not in men (HR, 1.32; 95% CI, 0.66-2.64; p=0.422). CONCLUSIONS An increased level of UA was associated with MACE more strongly in women than in men with ACS. These results suggest that there are gender differences in the association of UA level with the prognosis in patients with ACS.

Abstract
The adhesion force on surfaces has received attention in numerous scientific and technological fields, including catalysis, thin-film growth, and tribology. Many applications require knowledge of the strength of these forces as a function of position in three dimensions, but until now such information has only been theoretically proposed. Here, we demonstrate an approach based on scanning probe microscopy that can obtain such data and be used to image the three-dimensional surface force field of continuous nanoscale protrusions. We present adhesion force maps with nanometer and nanonewton resolution that allow detailed characterization of the interaction between a surface and a thin carbon nanofiber (CNF) rod synthesized by plasma-enhanced chemical vapor deposition (PECVD) at the end of a tip on a scanning probe microscope cantilever in three dimensions. In these maps, the positions of all continuous nanoscale protrusions are identified and the differences in the adhesive forces among limited areas at inequivalent sites are quantified.

Abstract
BACKGROUND The association of Mehran risk score (MRS) with long-term prognosis in patients treated with percutaneous coronary intervention (PCI) has not been fully reported. We investigated the association between MRS and clinical outcomes in patients who underwent PCI. METHODS Study subjects comprised 2198 patients treated with PCI from the Ibaraki Cardiovascular Assessment Study multicenter registry, excluding patients receiving hemodialysis or who died within 7 days. We categorized them into 4 groups according to MRS (low-risk: ≤5; medium-risk: 6-10; high-risk: 11-16; and very high-risk: ≥16). Contrast-induced acute kidney injury (CI-AKI) was defined as an increase of 0.5mg/dL or 25% in pre-PCI serum creatinine within 1-week post procedure. We evaluated CI-AKI and major adverse cardiac and cerebrovascular events (MACCE), and defined as all-cause death, myocardial infarction, congestive heart failure, or cerebrovascular disorder (stroke or transient ischemic attack). RESULTS A total of 192 (8.7%) patients developed CI-AKI. At multivariate analysis, odds ratio for CI-AKI was 4.09 (95% CI: 1.72-9.17, p=0.002) in the very high-risk group, 1.49 (95% CI: 0.89-2.42, p=0.120) in the high-risk group, and 1.08 (95% CI: 0.74-1.54, p=0.693) in the medium-risk group, as compared with the low-risk group. MACCE in the very high-risk group was more than 5-fold higher [hazard ratio (HR) 5.40, 95% CI: 2.96-9.28, p<0.001] compared with the low-risk group and was also increased in the high-risk (HR 3.72, CI: 2.59-5.32, p<0.001) and medium-risk groups (HR 1.97, CI: 1.45-2.69, p<0.001). Kaplan-Meier analysis showed that increasing risk for MACCE was seen across the groups as MRS increased (p<0.001). CONCLUSION MRS might provide potentially useful information for prediction of CI-AKI and clinical outcomes after PCI.

Abstract
We developed and successfully fabricated a plannar light source device using a phosphor screen with single-walled carbon nanotubes (SWCNTs) as field emitters in a simple diode structure composed of the cathode containing the highly purified and crystalline SWCNTs dispersed into an organic In2O3-SnO2 precursor solution and a non-ionic surfactant. The cathode was activated by scratching process with sandpaper to obtain a large field emission current with low power consumption. The nicks by scratching were treated with Fourier analysis to determine the periodicity of the surface morphology and designed with controlling the count number of sandpapers. The anode, on the other hand, was made with phosphor deliberately optimized by coverage of ITO nanoparticles and assembled together with the cathode by the new stable assembling process resulting to stand-alone flat plane-emission panel. The device in a diode structure has a low driving voltage and good brightness homogeneity in that plane. Furthermore, field emission current fluctuation, which is an important factor in comparing luminance devices too, has a good stability in a simple diode panel. The flat plane-emission device employing the highly purified and crystalline SWCNTs has the potential to provide a new approach to lighting in our life style.

Abstract
BACKGROUND The association between contrast-induced acute kidney injury (CI-AKI) and chronic kidney disease (CKD) in patients with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI) has not been fully reported. We evaluated the association of CI-AKI on cardiovascular events in ACS patients with CKD. METHODS A total of 1059 ACS patients who underwent emergent PCI in our multicenter registry were enrolled (69±12 years, 804 men, 604 STEMI patients). CKD was defined as at least stage 3 CKD, and CI-AKI was defined as an increase of at least 0.5 mg/dL and/or an increase of at least 25% of pre-PCI to post-PCI serum creatinine levels within 1 week after the procedure. Primary endpoints included cardiovascular death, myocardial infarction, and cerebrovascular disorder (stroke or transient ischemic attack). RESULTS In our study, 368 (34.7%) patients had CKD. During follow-up periods (435±330 days), CI-AKI and primary endpoints occurred in 164 (15.5%) patients and 106 (10.0%) patients, respectively. Multivariate Cox proportional hazards model revealed that age, female gender, peak creatinine kinase>4000, IABP use, CI-AKI (hazard ratio [HR], 2.17; 95% confidential interval [CI], 1.52 to 4.00; P<0.001), and CKD (HR, 1.66; 95% CI, 1.01 to 2.72; P=0.046) were independent predictors of primary endpoints. Kaplan-Meier analysis showed that occurrence of primary endpoints increased significantly with an increase in CKD stage, and CI-AKI yielded worse long-term prognosis at every stage of CKD (P<0.001). CONCLUSIONS CI-AKI was revealed to be a significant incremental predictor of cardiovascular events at each stage of CKD in ACS patients.

Abstract
A 41-year-old man was admitted with acute heart failure and shock status. An echocardiogram showed a mobile tumor obstructing blood flow through the mitral valve with a stalk on the posterior left atrium (LA) wall. Emergent open-heart surgery was performed to resect the tumor (77×36×30 mm). Histological examination confirmed that it was an undifferentiated pleomorphic sarcoma. Unfortunately, positron emission tomography performed five months after surgery demonstrated a local recurrence around the right pulmonary vein and LA. We performed proton beam radiotherapy to treat the local recurrence, and it was effective. The patient has survived more than one year since the first life-threatening heart failure episode.

Abstract
BACKGROUND To evaluate the incidence and clinical predictors of contrast-induced acute kidney injury (CI-AKI) in patients with ST-segment elevation myocardial infarction (STEMI), unstable angina pectoris/non-STEMI (UAP/NSTEMI), and stable AP (SAP) undergoing percutaneous coronary intervention (PCI). METHODS AND RESULTS We enrolled 1,954 patients (SAP, n=1,222; UAP/NSTEMI, n=277; STEMI, n=455) who underwent PCI. Patients were categorized according to contrast media volume/estimated glomerular filtration rate ratio (CV/eGFR low: <2.0, mid: 2.0-2.9, high: ≥3.0). CI-AKI was defined as an increase in serum creatinine of 0.5mg/dl or 25% within 1 week from contrast-medium injection. The incidence of CI-AKI was highest among the STEMI patients (SAP, 4.24%; UAP/NSTEMI, 10.7%; STEMI, 16.1%, P<0.01). Significant predictors of CI-AKI were emergency PCI (odds ratio [OR] 3.70; 95% confidence interval [CI] 2.55-5.37; P<0.001), ejection fraction <40% (OR 2.04; 95% CI 1.24-3.36; P=0.005), and hemoglobin <10g/dl (OR 0.02; 95% CI 1.17-4.55; P=0.02) after multivariate logistic regression analysis. In the SAP group, a CV/eGFR ratio ≥3.0 was a significant predictor of CI-AKI (P=0.048), but not in UAP/NSTEMI and STEMI patients. CONCLUSIONS UAP/NSTEMI and STEMI patients undergoing emergency PCI were at high risk for CI-AKI regardless of CV/eGFR ratio. Minimizing the dose of contrast medium based on eGFR might be valuable in reducing the risk of CI-AKI in SAP patients.
