Abstract
Mental nerve paresthesia is a serious postoperative complication of mandibular third molar extraction. It appears that no study has examined the relationship between the surface morphology of the mandibular third molar roots and the possibility of mental nerve paresthesia following tooth extraction. Therefore, the root morphology of the mandibular third molars was examined according to age using dental cone beam computed tomography (CBCT), and the possibility of mental nerve paresthesia following tooth extraction was evaluated. The study included 1216 patients who had undergone mandibular third molar extractions. The root morphology of 1534 teeth in 791 patients who had CBCT performed before surgery was studied. Factors evaluated were age, complete or incomplete formation of the mandibular third molar roots, periodontal ligament atrophy of the mandibular third molar roots, hypercementosis, and mandibular canal deformation. Mandibular third molar root formation was completed between the ages of 19 and 30 years. Complete formation of the mandibular third molar roots (P = 0.002) and deformation of the mandibular canal (P < 0.001) were identified as risk factors for mental nerve paresthesia. These findings suggest that the risk of mental nerve paresthesia could be reduced if the extraction of third molars is performed prior to complete root formation.

Abstract
We encountered two consecutive cases of adult-onset Kawasaki disease (AKD) that were difficult to diagnose. In both cases, Kawasaki disease was not considered as a differential diagnosis in the early stages. However, it was possible to make a diagnosis by citing the disease as a differential diagnosis and introducing the patients to the pediatrics department. AKD has a minimal incidence rate and may have a clinical course different from that of childhood-onset Kawasaki disease. Therefore, it is necessary to incorporate Kawasaki disease into the differentiation of an adult fever and to consult with a pediatrician for its diagnosis.

Abstract
A 5-year-old, castrated, male domestic short-haired cat presented with neurological deficits in the pelvic limbs, back pain and dysuria. Magnetic resonance imaging showed a mass lesion caudal to the L4 vertebrae. In addition, suspected haemorrhage was observed at the cranial aspect of the mass. There was no evidence to support the presence of extravertebral intrusion or vertebral body, osteolysis. Dorsal laminectomy and durotomy were performed to debulk the intraspinal mass. Histopathological and immunohistochemical assessment revealed a primitive neuroectodermal tumour (PNET). To our knowledge, this is the first report to describe the clinical and pathological features and imaging diagnosis of intraspinal PNET without extraspinal invasion in a cat.

Abstract
BACKGROUND Adding bevacizumab to first-generation epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) prolonged the progression-free survival (PFS), but limited data are available for second-generation EGFR-TKIs. AfaBev-CS is a randomized, phase II trial comparing afatinib plus bevacizumab and afatinib alone as first-line treatment. PATIENTS AND METHODS Untreated patients with non-squamous non-small cell lung cancer (NSCLC) harboring EGFR mutations (Del19 or L858R) were enrolled and randomly assigned to receive either afatinib (30 mg) plus bevacizumab (AfaBev group) or afatinib (40 mg) monotherapy (Afa group). The primary endpoint was PFS. The power was >50% under the assumptions of a median PFS of 12 months for the Afa group and hazard ratio (HR) of 0.6 for the AfaBev group. RESULTS Between August 2017 and September 2019, 100 patients were enrolled. There was no significant difference in PFS between the groups. The median PFS was 16.3 and 16.1 months for the AfaBev and Afa groups, respectively, with an HR of 0.865 (95% confidence interval [CI], 0.539 to 1.388; p = 0.55). In terms of overall survival, there was no significant difference between the groups (HR, 0.84; 95% CI, 0.39 to 1.83; p = 0.67). The overall response rate was 82.6% and 76.6% in the AfaBev and Afa groups, respectively (p = 0.61). Grade ≥ 3 diarrhea, hypertension, acneiform rash, paronychia, and stomatitis were frequently observed in the AfaBev group. CONCLUSIONS This study failed to show efficacy of AfaBev over Afa for improving PFS in untreated patients with EGFR-mutated NSCLC.

Abstract
We discovered a simple regime where a near-critical plasma irradiated by a laser of experimentally available intensity can self-organize to produce positrons and accelerate them to ultrarelativistic energies. The laser pulse piles up electrons at its leading edge, producing a strong longitudinal plasma electric field. The field creates a moving gamma-ray collider that generates positrons via the linear Breit-Wheeler process-annihilation of two gamma rays into an electron-positron pair. At the same time, the plasma field, rather than the laser, serves as an accelerator for the positrons. The discovery of positron acceleration was enabled by a first-of-its-kind kinetic simulation that generates pairs via photon-photon collisions. Using available laser intensities of 10^{22} W/cm^{2}, the discovered regime can generate a GeV positron beam with a divergence angle of around 10° and a total charge of 0.1 pC. The result paves the way to experimental observation of the linear Breit-Wheeler process and to applications requiring positron beams.

Abstract
Focal segmental glomerulosclerosis (FSGS) is a common glomerular injury leading to end-stage renal disease. Monogenic FSGS is primarily ascribed to decreased podocyte integrity. Variants between residues 184 and 245 of INF2, an actin assembly factor, produce the monogenic FSGS phenotype. Meanwhile, variants between residues 57 and 184 cause a dual-faceted disease involving peripheral neurons and podocytes (Charcot-Marie-Tooth CMT/FSGS). To understand the molecular basis for INF2 disorders, we compared structural and cytoskeletal effects of INF2 variants classified into two subgroups: One (G73D, V108D) causes the CMT/FSGS phenotype, and the other (T161N, N202S) produces monogenic FSGS. Molecular dynamics analysis revealed that all INF2 variants show distinct flexibility compared to the wild-type INF2 and could affect stability of an intramolecular interaction between their N- and C-terminal segments. Immunocytochemistry of cells expressing INF2 variants showed fewer actin stress fibers, and disorganization of cytoplasmic microtubule arrays. Notably, CMT/FSGS variants caused more prominent changes in mitochondrial distribution and fragmentation than FSGS variants and these changes correlated with the severity of cytoskeletal disruption. Our results indicate that CMT/FSGS variants are associated with more severe global cellular defects caused by disrupted cytoskeleton-organelle interactions than are FSGS variants. Further study is needed to clarify tissue-specific pathways and/or cellular functions implicated in FSGS and CMT phenotypes.

Abstract
Neuroblastoma (NB) is a neural crest-derived malignant tumor which is diagnosed during infancy in approximately 40% of cases; spontaneous regressions are observed, but there are varying degrees of severity. Treatment is indicated if an infant's condition is at risk of deterioration. Herein, we report the case of a 42-day-old boy who presented with hepatomegaly and was diagnosed with stage MS NB. A pathological diagnosis of "poorly differentiated neuroblastoma with low mitosis-karyorrhexis index, favorable histology" was made; his tumor cells were hyperdiploid and MYCN was not amplified. Because he had respiratory distress caused by the rapidly evolving hepatomegaly, two cycles of chemotherapy containing vincristine and cyclophosphamide were administered in the second and fourth weeks of admission; however, his abdominal tumor did not shrink. In the sixth week of admission, chemotherapy was revised to pirarubicin and cyclophosphamide, and the tumor began to shrink. After discharge, there was no re-elevation of tumor markers; after 1 year, the hepatomegaly and liver metastases disappeared. During the 5-year follow-up, his growth and development were normal and he progressed without sequelae. A regimen that includes pirarubicin could merit further study in the treatment of early infants with stage MS low-risk NB who are at risk of complications.

Abstract
This study aimed to investigate the effects of intravenous pimobendan on cardiovascular function and to determine the appropriate dose for clinical usage in cats. Six purpose-bred cats received one of the following treatments: intravenous pimobendan at a single dose of 0.075 mg/kg (low dose [LD] group), 0.15 mg/kg (middle dose [MD] group), 0.3 mg/kg (high dose [HD] group), or saline at 0.1 mL/kg (placebo group). Echocardiography and blood pressure measurements were performed before and 5, 15, 30, 45, and 60 minute after drug administration for each treatment. In the MD and HD groups, the fractional shortening, peak systolic velocity, cardiac output, and heart rate increased significantly. There were no significant differences in blood pressure among the groups. Intravenous pimobendan at 0.15-0.3 mg/kg increased the fractional shortening, peak systolic velocity, cardiac output in healthy cats.

Abstract
This study aimed to determine the characteristics and reference values of each vertebra in the cervicothoracic region by performing diffusion tensor imaging (DTI) scans and analyzing DTI parameters in normal Beagle dogs. In five adult Beagles under anesthetic maintenance, DTI was performed using a 1.5-T magnetic resonance imaging (MRI) scanner. Axial DTI was performed using three overlapping slabs to cover the cervical and thoracic spinal cords. After post-processing, DTI parameters were calculated along the entire spinal cord. Among DTI parameters, fractional anisotropy, relative anisotropy, and axonal diffusivity significantly decreased in the caudal direction. However, the apparent diffusion coefficient, radial diffusivity, and mean diffusivity values were not significantly correlated with vertebral levels. We provide evidence for the existence of segment-dependent DTI parameters in the canine cervical spinal cord. Therefore, comparisons of DTI parameters between lesions at different vertebral levels should be avoided unless normative data are available. Furthermore, the DTI data obtained in this study may contribute to the development of a clinical reference for spinal cord evaluation in dogs using DTI parameters.

Abstract
Coronary aneurysm secondary to coronary fistula is a rare condition, with no existing report on its pathological examination. We report the case of a patient diagnosed with a right coronary artery fistula with coronary aneurysm during the fetal period. During follow-up after delivery, the aneurysm became larger, even though the shunt size decreased. We were afraid the aneurysm would rupture and therefore, planned elective catheter embolization. At the age of 4 years, the patient underwent surgery, which involved closing the fistula and making the lumen of the aneurysm smaller. However, the surgery was not catheter embolization as planned because segment 3 branched off from the largest aneurysm where we planned to embolize. Pathologically, the structure of the coronary artery differed from that of a healthy one, with thickened intima and media, fewer scattered smooth muscle cells, widely distributed elastic fibers, and mucoid degeneration in the media. The structure of the coronary artery suggested that the vessel wall was weak and that the aneurysm would rupture if not treated. Postoperative coronary angiography showed that segment 2 was obstructed, while the collaterals from the left coronary artery perfused the area. We could have treated the fistula with a catheter as scheduled.

Abstract
9112 Background: Adding Bev to erlotinib prolonged PFS in NEJ026 and CTONG1509 trials, but limited data are available adding Bev to a second-generation EGFR-tyrosine kinase inhibitor. AfaBev-CS is a Japanese no-profit, randomized, open-label, multicenter phase II trial of Afa plus Bev vs Afa alone as first-line treatment for EGFR-mutated advanced NSCLC. Methods: This study enrolled untreated pts of advanced non-squamous NSCLC harboring EGFR sensitizing mutation (Del19 or L858R) and without symptomatic brain metastases. 100 eligible pts were randomized in a 1:1 ratio to receive either Afa (30 mg, daily) plus Bev (15 mg/kg, every 3 weeks) (AfaBev arm) or Afa (40 mg, daily) monotherapy (Afa arm), and stratified according to stage, EGFR mutation status and institution. The primary endpoint was PFS and the secondary endpoints were OS, tumor response and time to treatment failure. The sample size was set in terms of feasibility. The power is greater than 50% under the assumptions of a median PFS of 12 months for the Afa arm and HR of 0.6 for the AfaBev arm, with an accrual of 2.5 years and a minimum planned follow-up period of 2 years with the type 1 error of 0.05 (two-sided). Results: Between August 2017 and September 2019, 100 pts were enrolled (each arm, 50 pts). At a median follow-up of 31.3 months for all randomized pts, total 69 events occurred. Median PFS was 16.3 months for AfaBev arm and 16.1 months for Afa arm, with a hazard ratio (HR) of 0.865 (95%CI, 0.539 – 1.388; loglank p = 0.5476). In subgroup analysis, pts < 70 years old (HR 0.347) and pts with brain metastasis (HR 0.353) showed better trend of PFS in AfaBev arm. On the other hand, pts ≥ 70 years old (HR 1.738) and pts without brain metastasis (HR 1.196) did not show better trend in AfaBev arm. In terms of OS, result was immature because number of events was still small. Objective response rate was 77.6% in AfaBev arm and 72.0% in Afa arm. Severe adverse events were observed in 11 pts for each arm. Grade 3 or more diarrhea, hypertension, rash acneiform, paronychia and stomatitis were frequently observed in AfaBev arm. Pneumonitis was not observed for AfaBev arm and observed in 3 (6.0%) for Afa arm, and grade 3 in one patient. Conclusions: This study failed to show the efficacy of AfaBev arm for improving PFS in untreated pts with EGFR mutated non-squamous NSCLC. In pts < 70 years old, Afa plus Bev might be promising. Clinical trial information: jRCTs061180006.

Abstract
Background: Oral food challenge (OFC) is the most reliable method for diagnosing food allergies. However, the scarcity of long-term data on eating habits of people after a negative OFC poses a challenge for provisional medical care. Objective: This study was performed to investigate the percentage of people who could reintroduce eggs into their diet several years after an OFC. Methods: Study participants included 0–6-year-old children with negative results from an OFC using one egg as the food allergen, boiled for 20 min, from January 2012–March 2017, 1–3 years after the OFC. Results: A total of 72 subjects were analyzed, out of which 52 were males (72.2%). The median age (range) was 20 months (16–32.3), and the median age (range) at the first OFC was 15 months (12.8–23.3). Eggs were reintroduced in 62 cases (86.1%), while 10 cases (13.9%) did not undergo any diet change. The adjusted odds ratio (OR, 95% CI), with post-OFC to pre-OFC anxiety ≥ 0.2, was 9.4 (1.0–86), p = 0.04; OR for allergic symptoms that occurred post-OFC was 2.2 (0.45–11), p = 0.34; OR for initial OFC at an age of ≥15 months was 3.2 (0.54–19), p = 0.2; and OR for the history of anaphylaxis from eggs was 0.17 (0.02–1.5), p = 0.11. Conclusion: Most cases reintroduced eggs after an OFC. However, reintroduction did not occur in some cases, which was associated with greater anxiety among caregivers post-OFC. If the caregiver's anxiety is intense, it is necessary to provide psychological intervention and dietary guidance when reintroducing eggs at home after an OFC and to follow-up outpatient long-term progress.

Abstract
We examined the chemical constitution of the red alga Laurencia saitoi Perestenko, collected from Katsuura, Boso Peninsula, Chiba Prefecture, Japan. This specimen produced a new polyhalogenated acetogenin, named katsuurallene (1), which structure was determined by the spectral methods, along with known diterpene, deoxyparguerol (2) and triterpene, thyrsiferol (3). In this paper we describe the structural elucidation of katsuurallene together with some biological activities.

Abstract
We report the case of a 4-year-old boy with coarctation of the aorta resulting from persistent fifth aortic arch (PFAA), a rare abnormality, along with an interrupted fourth aortic arch. When he visited a general practitioner with an upper respiratory infection, a heart murmur was noted. Computed tomography findings led to the diagnosis of PFAA with an interrupted fourth aortic arch. He underwent aortic arch repair, excision of the fifth aortic arch, and anastomosis of the original arch with the descending aorta. Pathologically, the tissue of the fifth aortic arch was different from that of the normal aortic arch.

Abstract
INTRODUCTION Osimertinib is a tyrosine kinase inhibitor that targets the epidermal growth factor receptor. Elevated serum creatine kinase level is an uncommon adverse event associated with osimertinib treatment for lung cancer. CASE REPORT We report a previously healthy 56-year-old woman who developed elevated serum creatine kinase levels during osimertinib monotherapy for epidermal growth factor receptor mutation-positive lung adenocarcinoma. MANAGEMENT & OUTCOME During treatment, she experienced leg cramps and her serum creatine kinase levels increased, peaking at 989 U/l. Further investigation revealed no evidence of cardiotoxicity or myositis; thus, osimertinib-induced myopathy was assumed to be the cause of her elevated serum creatine kinase levels. We successfully managed both lung cancer and osimertinib-induced myopathy using 1-week pauses of osimertinib therapy without dose reduction. DISCUSSION Short-term suspension of osimertinib without dose reduction may be a reasonable option for osimertinib-induced myopathy.

Abstract
A 36‐month‐old female Pembroke Welsh Corgi with a cardiac murmur weighing 12.6 kg was referred to the Matsubara Animal Hospital cardiology service. Echocardiography revealed a patent ductus arteriosus. The dog underwent ductus arteriosus closure using an Amplatz Canine Duct Occluder. After the operation, we suspected coagulation and a platelet disorder because of the slightly increased haemorrhage during the operation, postoperative purpura around the surgical wound inside of the thigh, and dog breed, which is known to be commonly affected with von Willebrand disease (vWD). Subsequently, type 1 vWD was confirmed. Complete occlusion was achieved 1 month after the operation; however, 2 months after the operation, recanalization appeared. Recanalization progressed gradually; cardiac redilation was not detected 6 years after the operation. The late recanalization was most likely associated with vWD. In canine breeds pre‐disposed to developing vWD, pre‐operative testing may be indicated prior to patent ductus arteriosus occlusion, though the prevalence of vWD is rare.

Abstract
Clinical data on coronavirus disease-19 (COVID-19) in children during the management of nephrotic syndrome (NS) is lacking. Patients on prednisolone are compromised hosts at the risk of severe infections. Some infections may induce NS relapse. We describe the clinical course of a child with NS and COVID-19. A 3-year-old boy was admitted with clinical and laboratory findings indicative of NS. Induction therapy with prednisolone (2 mg/kg/day) induced complete remission. While tapering the dose, he was infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). He developed a high fever and periorbital edema. Urinalysis revealed proteinuria (protein-creatinine ratio: 6.3 g/gCr). He was transferred to our hospital for the concurrent management of COVID-19 and NS relapse. As proteinuria worsened, the prednisolone dose was increased to 2 mg/kg/day. Proteinuria gradually improved, and remission was noted a week after initiating full-dose steroid treatment. The fever subsided after 2 days without treatment for COVID-19. Anti-SARS-CoV-2 antibody including IgG levels decreased in the early convalescent phase. To the best of our knowledge, this is the first reported case with the recurrence of NS triggered by the SARS-CoV-2 infection in Asia. SARS-CoV-2 infection may induce NS relapse. Daily administration of full-dose of prednisolone may be effective for managing the recurrence of NS associated with SARS-CoV-2 infection.

Abstract
BACKGROUND In a phase I study, afatinib (30 mg/body daily) plus bevacizumab (15 mg/kg every 3 weeks) was well tolerated and showed favourable outcomes in patients with epidermal growth factor receptor (EGFR)-mutant advanced non-small-cell lung cancer. Herein, we report the 2-year progression-free survival, overall survival and safety profile of these patients. METHODS Chemo-naïve patients with EGFR-mutant advanced non-small-cell lung cancer were enrolled. One group of patients received 40 mg afatinib daily and 15 mg/kg bevacizumab every 3 weeks (level 0) until disease progression or severe toxicity. Another group of patients received 30 mg afatinib daily and the same dose of bevacizumab (level 1). Dose-limiting toxicity was the primary endpoint, whereas long-term progression-free survival, overall survival and tolerability were secondary endpoints. Survival rates were estimated using the Kaplan-Meier method. RESULTS The study included 19 patients (level 0: 5; level - 1: 14). Until the data cut-off date, seven patients continued the treatment, whereas 12 discontinued due to disease progression (n = 5) or toxicity (n = 7). The median PFS was 24.2 months, while the median overall survival was not reached. All patients developed adverse effects. Diarrhoea and skin rash were frequently observed as severe adverse events (grade 3). A secondary EGFR mutation (T790M) was detected in two patients after progression. CONCLUSIONS Prolonged follow-up revealed that combination therapy with afatinib and bevacizumab might improve survival outcomes in EGFR-mutant advanced non-small-cell lung cancer patients and seems to be promising.

Abstract
Background Kimura’s disease (KD) is a rare chronic inflammatory disease of unknown etiology. Clinically, KD is characterized by nodular subcutaneous masses, that are typically localized to the neck and head. Involvement of the lacrimal glands and limbs is uncommon and seldom reported. Case presentation We report a case of a 4-year-old Japanese boy presenting with bilateral upper eyelid swelling with nodular subcutaneous lesions and peripheral eosinophilia. Based on clinical, histopathological, and laboratory findings, the patient was diagnosed with KD. An itchy subcutaneous mass on the left arm developed at the age of 14 years. Treatment with steroids was effective. However, as the steroids were tapered after the patient developed side effects, the masses relapsed within a few months. Treatment with cyclosporine A was then initiated, which led to an improvement of clinical features and serial levels of cytokines. Conclusions We report a rare case of KD with a peculiar clinical presentation. The patient responded well to treatment with cyclosporine A.

Abstract
INTRODUCTION The effects of pimobendan on the heart rhythm in cats are unknown. The purpose of this pilot study was to evaluate the effect of pimobendan on the cardiac rhythm and selected echocardiographic parameters of cats. ANIMALS, MATERIALS, AND METHODS Six clinically healthy cats received each of four medication protocols for 15 days, with a washout period of at least one month between each protocol. The protocols were, pimobendan 0.5 mg/kg twice daily (high dosage group), pimobendan 0.25 mg/kg twice daily (standard dosage group), pimobendan 0.125 mg/kg twice daily (low dosage group), and Biofermin R, one tablet twice daily (placebo group). Twenty-four-hour ambulatory electrocardiogram recordings, blood pressure measurements, and echocardiographic examinations were performed after two weeks of each medication protocol. Electrocardiographic, echocardiographic, and blood pressure parameters were compared between the four groups. RESULTS The total number of escape/idioventricular/idiojunctional complexes in the high dosage group was significantly higher compared with the placebo, low dosage, and standard dosage groups (p < 0.001). The blood pressure; total number of heart beats per day; and mean, minimum, and maximum heart rates were not significantly different between the groups. The longitudinal strain rate and calculated cardiac output were significantly increased in the high and standard dosage groups. CONCLUSIONS The administration of pimobendan, especially at high doses, was associated with increased numbers of escape/idioventricular/idiojunctional complexes in some cats and echocardiographic parameters. Further studies are warranted to investigate both the mechanism underlying the observed changes and what, if any, clinical implications these changes might have in cats with heart disease.

Abstract
RATIONALE Oral cancer often causes secondary primary cancers in the upper gastrointestinal tract. However, there are no reports of secondary primary cancers in patients with oral squamous cell carcinoma and malignant lymphoma of the small intestine. This report describes a case of metachronous multiple primary cancers of the tongue and small intestine malignant lymphoma. PATIENTS CONCERNS The patient was admitted to our department with the chief complaint of pain in the right tongue. Partial tongue resection and supraomohyoid neck dissection were performed. One year after surgery, the patient experienced abdominal pain and bloody stools. DIAGNOSIS Diffuse large B-cell lymphoma (DLBCL) was diagnosed via histological examination. INTERVENTIONS A terminal ileum resection was performed. Postoperatively, the patient received 6 courses of rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP). OUTCOMES Five years after his initial diagnosis, there is no evidence of recurrence, metastasis, or other primary cancer. LESSONS Oral cancer patients should always be followed up owing to a possibility of malignant tumors in other areas.

Abstract
BACKGROUND The association of hypertension with congenital renal hypoplasia has been established. We report a case of an infant who underwent nephrectomy for hypertension. CASE PRESENTATION Magnetic resonance imaging for the mother revealed fetal renal masses, and fetal multicystic dysplastic kidney was suspected. Following birth, the baby developed hypertension. Numerous investigations revealed that the left kidney was non-functional, and she was initiated on benazepril hydrochloride. However, because the drug response was poor, the left kidney was removed at the age of 7 months. Examination of the renal specimen revealed abrupt transition from normal to atrophic cortex with lobar atrophy and cysts. Tubular atrophy, marked abnormal blood vessels with wall thickening, gathered immature glomeruli, and parenchymal destruction were observed. Renin was partially localized in the proximal tubules and the parietal epithelium of the Bowman's capsule in the immature glomeruli. We speculated that an abnormal vascular structure and irregular renin localizations may be the cause of hypertension. Serum renin and aldosterone levels gradually reduced post-surgery, reaching normal levels on the 90th postoperative day. A long follow-up is needed due to the possibility of the child developing hypertension in the future. CONCLUSION This is a case of an infant with MCDK, which discusses the clinicopathological features based on the pathophysiological analysis, including renin evaluation.

Abstract
Background Pulmonary lymphangitic carcinomatosis (PLC) is a metastatic lung disease of malignant tumors that spread through pulmonary lymphatic vessels. Although prompt diagnosis and specific treatment of PLC are required due to the poor prognosis associated with this disease, it is often challenging to determine the primary cancer site. Case presentation A 67-year-old Japanese woman presented to our hospital with a 10-day history of cough and dyspnea on exertion. Chest radiography and computed tomography (CT) revealed diffuse nodular opacities with interlobular septal thickening. Both bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) revealed carcinoma cells with unknown origin. Contrast-enhanced CT depicted a mass in the right ureter with hydronephrosis, and retrograde urography showed a narrowing of the right ureter. Urine cytology from her right ureter via ureteral catheter also revealed atypical cells, highly suggestive of malignancy. Immunohistochemical examination of lung specimens via TBLB showed results consistent with lung metastasis of ureteral cancer. Therefore, we arrived at a diagnosis of PLC secondary to ureteral cancer. Conclusions This case encouraged multidisciplinary discussion and a whole-body examination, including TBLB with immunohistochemistry, to determine the origin of PLC.

Abstract
INTRODUCTION Conventional cancer registries are suitable for simple surveillance of cancer patients, including disease frequency and distribution, demographics, and prognosis; however, the collected data are inadequate to clarify comprehensively diverse clinical questions in daily practice. METHODS We constructed an umbrella-type lung cancer patient registry (CS-Lung-003) integrating multiple related prospective observational studies (linked studies) that reflect clinical questions about lung cancer treatment. The primary endpoint of this registry is to clarify daily clinical practice patterns in lung cancer treatment; a key inclusion criterion is pathologically diagnosed lung cancer. Under this registry, indispensable clinical items are detected in advance across all active linked studies and gathered prospectively and systematically to avoid excessive or insufficient data collection. Researchers are to input information mutually, irrespective of the relevance to each researcher's own study. Linked studies under the umbrella of the CS-Lung-003 registry will be updated annually with newly raised clinical questions; some linked studies will be newly created, while others will be deleted after the completion of the analysis. Enrollment began in July 2017. DISCUSSION We successfully launched the umbrella-type CS-Lung-003 registry. Under this single registry, researchers collaborate on patient registration and data provision for their own and other studies. Thus, the registry will produce results for multiple domains of study, providing answers to questions about lung cancer treatment raised by other researchers. Through such analysis of each linked study, this registry will contribute to the comprehensive elucidation of actual daily practice patterns in lung cancer treatment. KEY POINTS CS-Lung-003 registry directly integrates multiple linked studies created under the umbrella of this cancer registry to solve various clinical questions regarding daily practice patterns of lung cancer treatment.

Abstract
Clostridioides difficile infection (CDI) is an important nosocomial infection and is the leading cause of infectious diarrhea in hospitalized patients. We aimed to assess the effect of bowel rest on the management of CDI. A single-center retrospective cohort study was conducted. The primary outcome was the composite of the all-cause mortality and CDI recurrence within 30 days. The main secondary outcome was switching from metronidazole to vancomycin. Of the 91 patients with CDI enrolled as the full cohort, 63 patients (69%) and 28 patients (31%) constituted the control group and the bowel rest group, respectively. After one-to-one propensity score matching, a total of 46 patients were included as the matched cohort. In the full cohort, the composite outcome occurred in 19.0% and 14.3% of the patients in the control and the bowel rest group, respectively (p = 0.768). In the matched cohort, it was 17.4% in each group. Although there was no statistically significant difference, the trend of switching was lower in the bowel rest group. The bowel rest may not affect the all-cause mortality and CDI recurrence within 30 days. However, in those prescribed bowel rest, switching from metronidazole to vancomycin may reduce.

Abstract
Tonsils are located mainly at the gateway of the respiratory tract, and are reportedly one of the secondary lymphatic organs of the immune system. The development of several diseases including IgA nephropathy (IgAN) is associated with inflammatory stimulation and an aberrant immune response of the tonsils. Several studies have reported an improvement in and/or an increase in the stability of the clinicopathological findings of patients with IgAN post tonsillectomy. However, the efficacy in and precise mechanism of the alleviation of symptoms of other renal diseases by tonsillectomy remain unknown. We hypothesize that tonsillectomy may play a potentially therapeutic role in renal diseases apart from IgAN, which are thought to be caused by an impaired regulation of the immune system.

Abstract
Abstract
Background
Soluble guanyl cyclase (sGC) is a receptor for nitric oxide (NO) and plays an important role in vascular tonus. sGC stimulant is a therapeutic agent for pulmonary hypertension and an advantage of sGC stimulant over phosphodiesterase (PDE)-5 inhibitors is that sGC stimulant exerts its effect even when NO production is reduced. NO derived from vascular endothelial cells is immediately absorbed by hemoglobin (Hb), which leads to the production of methemoglobin (Met-Hb) when oxidized. Previous report has shown that the therapeutic effect of PDE-5 inhibitors was associated with levels of Met-Hb.
Purpose
In this study, we examined the relationship between the effect of riociguat and levels of Met-Hb in patients with chronic thromboembolic pulmonary hypertension (CTEPH).
Methods
The study population comprised 18 patients with CTEPH. Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were assessed before and after administration of riociguat, and changes in mPAP and PVR were defined as ΔmPAP and ΔPVR, respectively. Since the level of Met-Hb was obtained as the percentage of Hb (FMet-Hb), the amount of Met-Hb was calculated by following formula:
Met-Hb (mg/dL) = Hb (g/dL) × FMet-Hb (%) × 10.
Results
The amount of Met-Hb value before administration of riociguat was significantly correlated with the degree of improvement in mPAP and PVR after administration of riocigat (R=−0.502, P<0.05 mPAP; R=−0.481, P<0.05 PVR, respectively) as shown in figures.
Conclusion
Our findings suggest that the level of Met-Hb before treatment may predict the therapeutic effect of sGC stimulants in patients with CTEPH.

Abstract
BACKGROUND Early multiple-drug therapy for severe childhood immunoglobulin A (IgA) nephropathy prevents the progression of nephritis and improves the long-term prognosis. Recent studies have focused on the relationship between the pathophysiology of IgA nephropathy and tonsillar focal infection, and the efficacy of tonsillectomy with methylprednisolone pulse therapy in children has been demonstrated. However, no study has reported on the relationship between the period from diagnosis to tonsillectomy and the long-term prognosis of IgA nephropathy. METHODS To clarify the long-term effects of an early tonsillectomy, 40 patients who were diagnosed with severe IgA nephropathy in childhood and underwent a tonsillectomy were divided into two groups based on the period from diagnosis to undergoing tonsillectomy: Group A, less than 3 years; and Group B, more than 3 years. The primary endpoint of this study was the change in the amount of proteinuria. Renal prognosis was evaluated 10 years after the diagnosis. RESULTS This study enrolled 40 patients diagnosed with severe IgA nephropathy in childhood who underwent tonsillectomy after multiple-drug therapy with/without methylprednisolone pulse therapy at Kindai University Hospital; eight patients were excluded based on the exclusion criteria. Group A consisted of 18 patients and Group B, 14 patients. Proteinuria and hematuria levels were significantly reduced in the early surgery group (P < 0.01). No significant differences were found in serum creatinine, uric acid, and IgA/C3 ratio. CONCLUSIONS High proteinuria levels worsen the renal prognosis in IgA nephropathy. Tonsillectomy in less than 3 years combined with multiple-drug therapy after the initial diagnosis could improve long-term prognosis.

Abstract
OBJECTIVES The purpose of this study was to determine the impact of ageing on the cardiovascular system of healthy adult cats. METHODS Six experimental cats were used. Echocardiography and measurements of systolic blood pressure (SBP) were performed every year for 8 years (from 1 year of age to 8 years of age) in all cats. Age-related changes to left ventricular (LV) structures, LV systolic and diastolic function, and SBP were assessed. RESULTS There were no significant changes in LV structures and SBP. Peak longitudinal strain rate during systole was decreased at 8 years of age, and peak longitudinal strain rate during diastole was decreased from 6 years of age. CONCLUSIONS AND RELEVANCE This study revealed that some measures of cardiac function recorded in six healthy cats from 1 to 8 years of age were affected as the cats got older; however, there were no structural changes or changes in measurements that are routinely assessed in clinical practice.

Abstract
An 87-year-old Japanese man presented to our hospital with a 5-day history of fever and neck pain. On physical examination, his stiff neck indicated restricted movement, especially on rotation. CT of the head revealed calcification of the atlantoaxial joint consistent with crowned dens syndrome, and celecoxib was started. Four days later, he returned to our emergency department as his neck pain and fever had not improved. Pneumonia and a urinary tract infection were suspected. The day following admission, blood culture results were positive for methicillin-resistant Staphylococcus aureus A contrast-enhanced CT revealed an upper cervical epidural abscess at the level of C1-C2. He was discharged following 8 weeks of antibiotic treatment.

Abstract
A 15-year old, female miniature dachshund was presented for a 5-year history of progressive dyspnoea. A laryngeal mass was detected on cervical radiographs. Surgery was performed 5 days later to reduce the volume of the mass and to obtain biopsy samples; the dyspnoea improved. Based on the histopathological findings, the mass was diagnosed as inflammatory polyp. This case of inflammatory polyp in the larynx suggests that it should be listed in the differential diagnoses for laryngeal masses in dogs and that surgical treatment may be curative.

Abstract
Genebanks provide access to diverse materials for crop improvement. To utilize and evaluate them effectively, core collections, such as the World Rice Core Collection (WRC) in the Genebank at the National Agriculture and Food Research Organization, have been developed. Because the WRC consists of 69 accessions with a high degree of genetic diversity, it has been used for >300 projects. To allow deeper investigation of existing WRC data and to further promote research using Genebank rice accessions, we performed whole-genome resequencing of these 69 accessions, examining their sequence variation by mapping against the Oryza sativa ssp. japonica Nipponbare genome. We obtained a total of 2,805,329 single nucleotide polymorphisms (SNPs) and 357,639 insertion-deletions. Based on the principal component analysis and population structure analysis of these data, the WRC can be classified into three major groups. We applied TASUKE, a multiple genome browser to visualize the different WRC genome sequences, and classified haplotype groups of genes affecting seed characteristics and heading date. TASUKE thus provides access to WRC genotypes as a tool for reverse genetics. We examined the suitability of the compact WRC population for genome-wide association studies (GWASs). Heading date, affected by a large number of quantitative trait loci (QTLs), was not associated with known genes, but several seed-related phenotypes were associated with known genes. Thus, for QTLs of strong effect, the compact WRC performed well in GWAS. This information enables us to understand genetic diversity in 37,000 rice accessions maintained in the Genebank and to find genes associated with different phenotypes. The sequence data have been deposited in DNA Data Bank of Japan Sequence Read Archive (DRA) (Supplementary Table S1).

Abstract
The objectives of this study were to investigate the usefulness of mitral flow propagation velocity (Vp) in cats by evaluating the effect of the flow pattern summation and evaluation of Vp variables in cats with hypertrophic cardiomyopathy (HCM). Healthy cats were categorized into summation (Sum) and separation (Sepa) groups to evaluate the effects of the flow pattern summation on Vp. Cats with HCM were categorized into HCM left atrial (LA) (-), LA (+), and LA (++) groups according to the degree of LA enlargement to investigate the feasibility of Vp. There were no significant differences noted in Vp between the Sum and Sepa groups and no significant correlation between Vp and heart rate. Decline of Vp was associated with the degree of LA enlargement. Mitral flow propagation velocity appeared to be clinically feasible in cats and could possibly be useful in the detection of diastolic dysfunctions in cats with HCM.

Abstract
This study aimed to assess the effects of atenolol on left ventricular (LV) and left atrial (LA) function in healthy cats and investigate the relationship between atenolol administration
and LA enlargement (LAE) in cats with hypertrophic cardiomyopathy (HCM). In study 1, nine experimental cats were used to assess the effects of atenolol in healthy subjects. Cats were
administered one of three medication protocols for 7 days: atenolol 6.25 mg/cat twice daily, 12.5 mg/cat twice daily, or placebo (biofermin) 1 tab/cat twice daily. In study 2, cats with HCM
were retrospectively recruited and divided into four groups according to atenolol administration [(control group (Cont) or atenolol administration group (Ate)] and the presence or absence of
LAE as follows: Cont LAE (−) group (n=42), Cont LAE (+) group (n=20), Ate LAE (−) group (n=17), and Ate LAE (+) group (n=12). LV and LA functions were compared in both studies. LV and LA
functions were decreased by atenolol administration in study 1. In study 2, the peak myocardial velocity during early diastole (E’) was significantly decreased in the Cont LAE (+), Ate LAE
(−), and Ate LAE (+) groups compared to that in the Cont LAE (−) group, but there were no significant differences between LAE (+) groups. Multivariate logistic analysis revealed that
atenolol administration was not associated with LAE. Diastolic dysfunction may be associated with LAE; however, atenolol administration did not affect LAE in cats with HCM.

Abstract
When the 1,1,4,4-tetraanilinobutadiene skeleton is attached with two halogenated aryl units at the 2,3-positions, they undergo facile two-electron oxidation to give stable dicationic dyes which exhibit a near-infrared (NIR) absorption whereas the neutral dienes show only pale color. Therefore, a distinct electrochromic response with an absorption change in the NIR region is achieved, which is attracting considerable recent attention from the viewpoint of bioimaging. Herein, we demonstrate that the redox potentials of the 1,1,4,4-tetraanilinobutadiene can be precisely controlled by the donating properties of the amino group on the aniline unit as well as the number of halogen atoms on the aryl units at 2,3-positions on the butadiene. In contrast, the NIR absorption bands mainly depend on the number of halogen atoms irrespective to the donating properties of aniline unit. Thus, the hexaarylbutadiene skeleton is proven to be a versatile scaffold to develop less-explored organic NIR electrochromic materials, whose redox and spectroscopic properties can be finely tuned by modifying/attaching the proper substituents.

Abstract
Background IgA deficiency associated with glomerulonephritis is rare. In particular, there is no prior report regarding the association between IgA deficiency and membranoproliferative glomerulonephritis (MPGN) in children. Herein, we describe the case of a 5-year-old girl with selective IgA deficiency and MPGN. Case presentation The patient presented with persisting urinary abnormality and hypocomplementemia following a group A treptococcal infection. Renal biopsy revealed the presence of diffuse mesangial hypercellularity, endocapillary proliferation, and focal thickening of the walls of the glomerular capillaries using light microscopy, with IgG and moderate C3 deposits observed using immunofluorescence. Electron microscopy images revealed nodular deposits in the subendothelial areas, with hump-shaped subepithelial deposits. The pathological diagnosis was confirmed as MPGN. Treatment using oral prednisolone (PSL), mizoribine (MZR), and angiotensin-converting enzyme inhibitors reduced the proteinuria. The PSL dose was gradually tapered, with the low dose of PSL and MZR continued for 4 years. Histological findings were improved on repeated renal biopsy, and PSL and MZR administration was discontinued. Conclusions We report a rare case of MPGN related to a streptococcal infection in a child. The clinical presentation included selective IgAD, with several pathological findings and a clinical course typical of glomerulopathy. The patient was successfully treated using multidrug therapy.

Abstract
Background Recently, the prevalence of food allergies during childhood is increasing, with fruits being common allergens. However, data on allergens that cause fruit and vegetable allergies and pollen-food allergy syndrome (PFAS) in childhood are relatively few. This study aimed to examine the allergens in fruit and vegetable allergies in pediatric patients and to determine the association between fruit and vegetable allergies and PFAS. Objective This study aimed to examine the current status of fruit and vegetable allergies in Japanese children. Methods This was a multicenter case series observational study. The participants included children aged <15 years who developed allergic symptoms after eating fruits and vegetables and subsequently received treatment in the Pediatric Department of 6 hospitals in the Osaka Prefecture in Japan during the study period from August 2016 to July 2017. Participants' information was obtained using a questionnaire, and data were obtained by performing several types of allergy tests using blood samples. Results A total of 97 children (median age, 9 years; 56 males) were included in the study. Apple was the most common allergen, followed by peach, kiwi, cantaloupe, and watermelon. A total of 74 participants (76%) exhibited allergic symptoms due to PFAS; moreover, pathogenesis-related protein-10 (PR-10) was the most common allergen superfamily. On the contrary, in the group where neither PR-10 nor profilin was sensitized, kiwi and banana were the most common allergens, and the age of onset was lower than that in the PFAS group. Specific antibody titer was significantly associated with Birch for Bet v1 and latex for Bet v2 (r = 0.99 and r = 0.89). Conclusion When we examine patients with fruit and vegetable allergies, we should first consider PFAS even in childhood specifically for children greater than 4 years old.

Abstract
Afterglow luminescent probes with high signal-to-background ratio show promise for in vivo imaging; however, such probes that can be selectively delivered into target sites and switch on afterglow luminescence remain limited. We optimize an organic electrochromic material and integrate it into near-infrared (NIR) photosensitizer (silicon 2,3-naphthalocyanine bis(trihexylsilyloxide) and (poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene]) containing nanoparticles, developing an H2S-activatable NIR afterglow probe (F12+-ANP). F12+-ANP displays a fast reaction rate (1563 ± 141 M-1 s-1) and large afterglow turn-on ratio (~122-fold) toward H2S, enabling high-sensitivity and -specificity measurement of H2S concentration in bloods from healthy persons, hepatic or colorectal cancer patients. We further construct a hepatic-tumor-targeting and H2S-activatable afterglow probe (F12+-ANP-Gal) for noninvasive, real-time imaging of tiny subcutaneous HepG2 tumors (<3 mm in diameter) and orthotopic liver tumors in mice. Strikingly, F12+-ANP-Gal accurately delineates tumor margins in excised hepatic cancer specimens, which may facilitate intraoperative guidance of hepatic cancer surgery.
