Abstract
Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor. Varying sized cysts and sheets composed of three cell types (epidermoid, intermediate, and mucous cells) with varying degrees of atypia form the characteristic histological appearance of MEC. MEC frequently contains a wide variety of modified tumor cells and can be entirely cystic or completely solid. Under these circumstances, MEC requires critical differentiation from many mimickers, ranging from simple cysts and benign tumors to high-grade carcinomas. Tumor-associated lymphoid proliferation and sclerotic changes in the stroma also contribute to diagnostic difficulties. Several well-known diagnostically challenging variants (oncocytic, clear cell, spindle cell, and sclerosing) exist in MEC. With the advent of studies on specific CRTC1/3::MAML2 fusion genes in MEC, newly proposed subtypes have emerged, including Warthin-like and non-sebaceous lymphadenoma-like MECs. In addition to the recently defined mucoacinar variant with a serous cell phenotype, MEC devoid of squamous differentiation has also been reported, implying the need to reconsider this basic concept. In this article, we outline the general clinical features and MAML2 status of conventional MEC and review the cytoarchitectural subtypes, with an emphasis on a pitfall in the interpretation of this histologically diverse single entity.

Abstract
BACKGROUND Practically every facet of the most common odontogenic tumor, odontoma, has been covered by an extensive volume of literature. However, uncertainty about its precise history has persisted. MATERIALS AND METHODS The historical evolution of odontoma was traced with reference to the original illustrations that accompanied European and American reports published at the beginning of the 19th century and also at the turn of the century. RESULTS The prevailing views regarding the first description of odontoma by Oudet of Paris in 1809 and the original designation "odontome" by Broca of Paris in 1867 are not entirely accurate. Before Broca's suggested term, "exostose dentaire" (dental exostosis) and "tumeur dentaire" (dental tumor) proposed by Oudet and Forget of Paris, respectively, were popular terms adopted in France, while in Briatin the terms "warty tooth" and "supernumerary teeth" proposed by Salter and Tomes of London, respectively, were widely coined. The original illustrations of complex odontoma were published by Wedl of Vienna in 1851, and in 1862 Tomes published the first drawing of compound odontoma denticles. Before the advent of diagnostic radiography in the early 1900s, spontaneous exposure or eruption of odontoma followed by secondary infection was very common. In 1887-1888, Bland Sutton of London criticized Broca's monumental research and formulated the first modern classification which, in essence, remains valid today. At that time, large osteomas of the maxilla were inappropriately classified as odontomas by many pathologists because of Bland Sutton's influential view. Interestingly, the first radiographic evidence of odontoma was published by the American oral surgeon Gilmer in 1899. CONCLUSION In view of their fundamental achievements, the names of Wedl, Salter, Broca and Bland Sutton have been closely associated with the true history of odontoma.

Abstract
The eponymous history of Warthin tumor (WT) is a fascinating issue in the field of salivary gland pathology. The late decades of the nineteenth century and the turn of the century saw notable German and French contributions on WT. Especially, the seminal 1910 paper of Albrecht and Arzt of Vienna is the foundation for the current knowledge of WT. It is generally believed that prior to this pioneering study, Hildebrand of Göttingen accurately described the lesion of WT in 1895. However, the historical origins of WT appear to be unsettled, and only a few German pathologists and surgeons are aware that dating back to 1885, the first recognizable reference to WT was that by the renowned German-Swiss pathologist Zahn, whose name is eponymously associated with "Zahn infarct" and "lines of Zahn". Two noted French surgeons with a major interest in pathology, Albarrán in 1885 and Lecéne in 1908, did not contribute to the topic. Since the 1950s, a mostly American group of pathologists and surgeons gradually adopted the term WT to replace the very accurate histologic descriptor "papillary cystadenoma lymphomatosum" coined by Warthin himself in 1929. It is our opinion that from a historical viewpoint, there is no particular reason why this tumor should have been named WT.

Abstract
REVIEW OF THE LITERATURE Cementoblastoma (CB) is unique among odontogenic tumors because its gross pathological anatomy is pathognomonic in most cases, i.e., a rounded calcified growth that is fused to the root of a tooth and completely encapsulated by fibrous tissue. The resulting radiographic appearance is a well-defined, globular mixed radiopaque/lucent or completely radiopaque mass obliterating some details of the root, with a thin radiolucent zone surrounding the central opacity. Although hundreds of publications have covered the clinicopathologic features of CB, almost nothing is known about its true history. Also it seems there is little understanding about how the term "CB" was originally introduced as a pathologic entity. This report covers some overlooked papers on CB dating back to the 19th century, including the first complete description in 1888 and the first radiographic presentation in 1906.

Abstract
BACKGROUND/PURPOSE Endoscopic ultrasound-guided liver biopsy (EUS-LB) is a novel liver biopsy technique. We aimed to evaluate the efficacy and safety of EUS-LB in comparison with percutaneous liver biopsy (PLB). METHODS This retrospective study evaluated the safety and efficacy of EUS-LB using a 19-gauge fine needle biopsy (FNB) needle compared with PLB using a spring-loaded 16-gauge needle in patients with diffuse liver disease at our hospital from April 2017 to December 2020. The primary outcomes included the total hepatic tissue surface area and the total number of portal tracts. Secondary outcomes included the success and adverse event rates. RESULTS Twenty patients each underwent EUS-LB and PLB. There was no statistical difference in the sum of liver tissue surface area (22 mm2 vs 22.6 mm2 , P = .910) and the total number of portal tracts (29 vs 25, P = .916). The success rate was 95% (19/20) for EUS-LB and 100% (20/20) for PLB (P = 1). There were two adverse events in the PLB group but none in the EUS-LB group (P = .487). CONCLUSIONS Endoscopic ultrasound-guided liver biopsy using FNB has an optimal tissue yield and success rate and is safe compared to PLB. Thus, EUS-LB may be a new alternative to PLB.

Abstract
A 60-year-old man with type-2 diabetes and chronic hepatitis C (HCV) was diagnosed with single hepatocellular carcinoma (HCC) of 67 mm in the hepatic posterior right lobe. Lenvatinib 8 mg was initiated but discontinued because of grade 3 liver injury. The patient continued to have prolonged liver injury and persistently high immunoglobulin G levels. Antinuclear antibody titer increased from 1:40 to 1:320. Histopathological examination of a liver biopsy specimen revealed interface hepatitis with lymphocyte and plasma cell infiltration, rosette formation, and emperipolesis, suggesting the possibility of autoimmune hepatitis (AIH). First, treatment with prednisolone was initiated; however, the response was poor. After starting glecaprevir/pibrentasvir (GLE/PIB) as direct-acting antivirals (DAA), HCV RNA rapidly disappeared, and serological liver function improved. After confirmation of sustained virological response 24, HCC recurrence was observed, and partial hepatectomy was performed. Background liver findings showed that liver parenchymal inflammation improved compared with that before DAA treatment. This is the first case of HCV-AIH overlap syndrome treated with DAA using GLE/PIB. Liver function improved within a short treatment period of 8 weeks, as confirmed using serology and histology.

Abstract
Temporal arteritis (TA) is a large-vessel vasculitis mostly seen in older patients. Amyloid A (AA) amyloidosis secondary to a chronic inflammation induces multiple organ dysfunctions, including a dysfunction of the gastrointestinal tract. Herein, we present a case of TA complicated by AA amyloidosis that was resistant to oral and intravenous steroids. An 80-year-old man with a history of new-onset headache, jaw claudication, and distended temporal arteries was referred to our department. On admission, the patient presented with tenderness and a subcutaneous temporal nodule in both temple arteries. Ultrasonography of the nodule revealed an anechoic perivascular halo surrounding the right temporal artery. Following the diagnosis of TA, high-dose prednisolone therapy was initiated. However, the patient presented with recurrent abdominal pain and refractory diarrhea. Due to the unclear origin of refractory diarrhea, an extensive workup, including biopsy of the duodenal mucosa, was performed. Endoscopy revealed chronic inflammation in the duodenum. Immunohistochemical analysis of duodenal mucosal biopsy samples revealed AA amyloid deposition resulting in the diagnosis of AA amyloidosis. After tocilizumab (TCZ) administration, refractory diarrhea reduced; however, the patient died of intestinal perforation 1 month after the start of TCZ administration. Gastrointestinal involvement was the main clinical manifestation of AA amyloidosis in the present case. This case highlights the importance of bowel biopsy screening for amyloid deposition in patients with unexplained gastrointestinal tract symptoms, even in a recent onset of large-vessel vasculitis. In the present case, the carriage of the SAA1.3 allele likely contributed to the rare association of AA amyloidosis with TA.

Abstract
OBJECTIVES Polymorphous adenocarcinoma (PAC) is a common intraoral minor salivary gland carcinoma in Western countries but is extremely rare in Japan. The current study aimed to characterize the clinicopathological features and status of molecular alterations of PAC-associated genes, such as (e.g., PRKD1/2/3, ARID1A, and DDX3X) in a large cohort of Japanese patients with PAC. MATERIALS AND METHODS We examined the cases of 36 Japanese patients with salivary gland PAC and 26 cases involving histopathological mimics. To detect gene splits, fluorescence in situ hybridization was carried out for PAC-associated genes. Additionally, we applied a SNaPshot multiplex assay to identify PRKD1 hotspot mutations. RESULTS This study revealed the indolent clinical course of PAC with a high 10-year overall survival rate (92.9%), accompanied by occasional local recurrences and cervical lymph node metastasis (both 23.3%). Twenty cases (55.6%) of PAC (but none of the mimics) exhibited alterations in at least one PAC-associated gene. Rearrangement of PAC-associated genes and PRKD1 E710D were identified in 17 (47.2%) and 4 (11.1%) cases, respectively; one case showed coexisting PRKD3 split and PRKD1 E710D. In the multivariate analysis, high clinical stage (P=0.0005), the presence of prominent nucleoli (P=0.0003), and ARID1A split positivity (P=0.004) were independent risk factors for disease-free survival. CONCLUSION Japanese patients with PAC showed clinicopathological features similar to those reported in Western countries. This study disclosed that PAC-associated genetic alterations were common and specific findings in PACs. The diagnostic role and possible prognostic significance of PAC-associated genetic alterations in PACs were suggested.

Abstract
BACKGROUND AND PURPOSE An accurate assessment of the hemodynamics of an intracranial dural AVF is necessary for treatment planning. We aimed to investigate the utility of 4D-MRA based on superselective pseudocontinuous arterial spin-labeling with CENTRA-keyhole and view-sharing (4D-S-PACK) for the vessel-selective visualization of intracranial dural AVFs. MATERIALS AND METHODS We retrospectively analyzed the images of 21 patients (12 men and 9 women; mean age, 62.2 [SD,19.2] years) with intracranial dural AVFs, each of whom was imaged with DSA, 4D-S-PACK, and nonselective 4D-MRA based on pseudocontinuous arterial spin-labeling combined with CENTRA-keyhole and view-sharing (4D-PACK). The shunt location, venous drainage patterns, feeding artery identification, and Borden classification were evaluated by 2 observers using both MRA methods on separate occasions. Vessel selectivity was evaluated on 4D-S-PACK. RESULTS Shunt locations were correctly evaluated in all 21 patients by both observers on both MRA methods. With 4D-S-PACK, observers 1 and 2 detected 76 (80.0%, P < .001) and 73 (76.8%, P < .001) feeding arteries of the 95 feeding arteries identified on DSA but only 39 (41.1%) and 46 (48.4%) feeding arteries with nonselective 4D-PACK, respectively. Both observers correctly identified 10 of the 11 patients with cortical venous reflux confirmed by DSA with both 4D-S-PACK and 4D-PACK (sensitivity = 90.9%, specificity = 90.9% for each method), and they made accurate Borden classifications in 20 of the 21 patients (95.2%) on both MRA methods. Of the 84 vessel territories examined, vessel selectivity was graded 3 or 4 in 73 (91.2%) and 66 (88.0%) territories by observers 1 and 2, respectively. CONCLUSIONS 4D-S-PACK is useful for the identification of feeding arteries and accurate classifications of intracranial dural AVFs and can be a useful noninvasive clinical tool.

Abstract
An 80-year-old woman was admitted to our hospital due to appetite loss and vomiting. A blood examination showed liver disorder with disseminated intravascular coagulation. All tumor markers and hepatitis virus markers were negative. Contrast-enhanced computed tomography did not show tumor lesions, bone lesions, lymphadenopathies, or thrombosis. A bone marrow biopsy revealed large, atypical cells with brown pigmentation and positive immunostaining for HMB-45, S100 proteins, and CD79a without myeloid or lymphoid markers. We experienced a case of disseminated carcinomatosis of the bone marrow due to malignant melanoma of unknown primary origin.

Abstract
Inverted ductal papilloma (IDP) is one of the least common benign papillary/cystic neoplasms of the salivary duct system, being characterized histologically by florid hyperplasia of duct-type epithelial cells into a cystic lumen near the orifice with occasional endophytic growth of the surface squamous epithelium along the terminus of the affected excretory duct. Given its rarity, the exact etiology of IDP remains to be defined. We herein present the first evidence of oncogenic HRAS mutation in a case of oral IDP. This finding, together with the frequent and specific BRAF mutations in sialadenoma papilliferum reported in the recent literature, supports an active role of the MAP-kinase cascade in the pathogenesis of benign papillary neoplasms of terminal duct origin.

Abstract
A 56-year-old man with chronic renal failure due to diabetic nephropathy had received maintenance dialysis (every 4 h, three times/week). A hypoechoic tumor measuring 67 × 50 mm in the right lobe of the liver was discovered following routine abdominal ultrasonography. Dynamic computed tomography showed a low-density liver tumor, enlarged hilar lymph node, and a small nodule on the dorsal side of the lower lobe of the left lung. Histopathological examination of the liver tumor revealed intrahepatic cholangiocarcinoma. We developed a chemotherapy treatment plan with gemcitabine, which can be performed concurrently with hemodialysis. Gemcitabine (1000 mg/m2, three times/cycle) was administered on Friday afternoon, and hemodialysis was performed on Tuesday, Thursday, and Saturday. Anemia and hypotension occurred after gemcitabine administration. Therefore, the dose of darbepoetin alpha was increased, and packed red blood cells were transfused. The patient was treated with gemcitabine for approximately 5 and a half months until computed tomography findings showed progressive disease; the survival time after treatment start was 8 months. Chemotherapy using gemcitabine has not been established in dialysis patients and has little evidence. We report a case of unresectable intrahepatic cholangiocarcinoma that developed during maintenance dialysis and was treated using gemcitabine chemotherapy.

Abstract
We report a palatal mucoepidermoid carcinoma (MEC) with unusual pathological features showing salivary duct cyst-like architecture, varied epithelial linings (excretory duct, mucous goblet cell, and apocrine epithelium phenotypes), scarce luminal tumor plaques, and a large intraluminal oncocytic polyp. To our knowledge, such a unicystic variant of MEC with pedicled oncocytic proliferation in the lumen is unprecedented in the literature. In this particular case, the microscopic diagnosis of MEC is problematic because of the large number of potential mimics.

Abstract
In this study, we investigate the flow of money among bank accounts possessed by firms in a region by employing an exhaustive list of all the bank transfers in a regional bank in Japan, to clarify how the network of money flow is related to the economic activities of the firms. The network statistics and structures are examined and shown to be similar to those of a nationwide production network. Specifically, the bowtie analysis indicates what we refer to as a "walnut" structure with core and upstream/downstream components. To quantify the location of an individual account in the network, we used the Hodge decomposition method and found that the Hodge potential of the account has a significant correlation to its position in the bowtie structure as well as to its net flow of incoming and outgoing money and links, namely the net demand/supply of individual accounts. In addition, we used non-negative matrix factorization to identify important factors underlying the entire flow of money; it can be interpreted that these factors are associated with regional economic activities. One factor has a feature whereby the remittance source is localized to the largest city in the region, while the destination is scattered. The other factors correspond to the economic activities specific to different local places. This study serves as a basis for further investigation on the relationship between money flow and economic activities of firms.

Abstract
A 25-year-old woman with fever and epigastric pain was referred to our hospital. Blood examination showed significant liver dysfunction, markedly high C-reactive protein (CRP 19.1 mg/dL) and procalcitonin (48.3 ng/mL) levels. Dynamic computed tomography showed a tumor approximately 120 mm in size in the right lobe of the liver, but with no abscess formation. The patient was hospitalized and started on antibiotics; her CRP level improved, but the procalcitonin level did not decrease. Histopathological examination of the liver tumor biopsy revealed fibrolamellar hepatocellular carcinoma (FLC). Positive staining of the FLC with an anti-procalcitonin antibody suggested the production of procalcitonin.

Abstract
Oocyte vitrification is an important approach for invitro gene banking of female germplasm; however, in pigs, it hampers embryo development. In cattle, vitrification at the MII stage was reported to alter epigenetic status in oocytes and even in subsequently developing embryos (Chen et al. 2016 Theriogenology 86, 868-878). The present study investigated the effect of vitrification at the immature stage of porcine oocytes on DNA methylation status and its relevance to subsequent embryo development. Immature cumulus–oocyte complexes were vitrified in microdrops and warmed (vitrified group) or treated with cryoprotectant agents (17.5% ethylene glycol + 17.5% propylene glycol, CPA group) by our method (Appeltant et al. 2018 Cryobiology 85, 87-94). Then they were subjected to IVM, parthenogenetic activation (PA), and embryo culture. From each batch, a group of oocytes was processed without treatment (control group). Oocyte survival and polar body extrusion were recorded after IVM. Cleavage and blastocyst developmental rates were recorded on Day 2 and 6 of culture, respectively (Day 0=PA). In each replication, DNA methylation was assayed in representative oocytes at the MII stage after IVM and in embryos at the 2- to 4-cell stage on Day 2 by immunostaining with 5-methylcytosine (5mC). Relative fluorescent intensity of 5mC in the chromatin was compared among groups. The experiment was replicated 3 times. Data were analysed by ANOVA. After IVM, there was no significant difference among the control, CPA, and vitrified groups in terms of the percentage of live oocytes (99.3, 96.4, and 94.0%, respectively) or polar body extrusion (88.6, 86.9, and 79.6%, respectively). After PA of oocytes with a polar body, there was no difference between the control and CPA groups in the percentage of cleavage (84.1 and 80.7%, respectively) or blastocyst development of cleaved embryos (63.3 and 79.3%, respectively). However, in the vitrified group, cleavage and blastocyst development rates (46.6 and 33.5%, respectively) were reduced (P<0.05) compared with the other groups. The 5mC fluorescence in the DNA of oocytes at the MII stage in the CPA and vitrified groups were similar and significantly lower than that in the control group (0.88±0.02, 0.87±0.001, and 1.0±0.02, respectively) but higher than that in the negative control processed without primary antibody (0.33±0.02). In the embryos at the 2- to 4-cell stage, 5mC fluorescence was not significantly different among the control, CPA, and vitrified groups (1.0±0.1, 0.99±0.1, and 0.96±0.1, respectively) but was significantly higher than that of the negative control (0.36±0.04). In conclusion, CPA treatment reduced DNA methylation levels in oocytes. However, it was restored during early embryo development and did not affect blastocyst development. The results suggest that reduced DNA methylation in vitrified oocytes is caused by CPA but it may not be responsible for their reduced ability to develop to blastocysts.

Abstract
Previous research revealed that vitrification at the immature (the germinal vesicle, GV) stage triggers premature meiotic resumption in cumulus-enclosed porcine oocytes and causes a damage in gap junctions (Appeltant et al. 2017 Reprod. Fertil. Dev. 29, 2419-2429). However, the correlation between the two phenomena was not investigated yet. The present research was conducted to clarify whether premature meiotic resumption is caused by gap junction disruption and to assess the importance of cumulus cells for the survival of porcine oocytes vitrified at the GV stage. Cumulus–oocyte complexes (COCs) were collected from 3- to 6-mm antral follicles of slaughtered gilts. Immediately after collection, approximately half of them were denuded mechanically (DOs). In each replicate, groups of COCs and DOs were processed without vitrification (control groups). Treatment groups of COCs and DOs were vitrified on Cryotop sheets in a combination of 17.5% propylene glycol and 17.5% ethylene glycol and warmed in 0.4M sucrose. The oocytes were then cultured for 22h in a chemically defined porcine oocyte medium (POM) supplemented with 10ngmL−1 epidermal growth factor, 10IUmL−1 equine chorionic gonadotrophin, 10IUmL−1 human chorionic gonadotrophin, and 1mM dibutyryl cAMP. After culture, COCs were denuded and oocyte survival was assessed by morphological evaluation of membrane integrity under a stereo microscope. Then, live oocytes were fixed and stained with 1% orcein and nuclear status was evaluated under a phase-contrast microscope. The experiment was replicated 5 times. Data were analysed by ANOVA followed by Tukey’s multiple comparisons test. After vitrification and culture, the survival rate in the COC group was higher (P<0.05) than that of the DO group (160/191=84.7±3.4% vs. 153/237=65.0±6.2%, respectively) but reduced (P<0.05) compared with those in the control COC and DO groups (138/143=96.6±1.0% and 152/153=99.3±0.6%, respectively). The majority of the control COCs and DOs were at the GV stage with similar percentages (95.6±2.2% and 94.0±2.2%, respectively). In contrast, the percentages of oocytes at the GV stage in the vitrified COC and DO groups were reduced (71.6±9.4% and 45.7±10.5%, respectively; P<0.05) compared with the control groups, which were associated with increased frequencies of diakinesis and MI stages. Percentages of oocytes at the GV stage in the vitrified COC and DO groups were not significantly different (P=0.23). In conclusion, cumulus cells can prevent vitrification-related membrane damage of oocytes. Furthermore, vitrification induced premature meiosis both in the cumulus-enclosed and denuded oocytes even in the presence of the meiotic inhibitor, dibutyryl cAMP. Nevertheless, cumulus removal without vitrification did not induce premature meiosis in the oocytes. Therefore, disruption in communication with cumulus cells might not be the primary reason for premature meiosis in vitrified oocytes.

Abstract
Peripheral ameloblastoma (PA) is a prototype form of extraosseous odontogenic tumor. As knowledge of PA has accumulated on the basis of more than 200 cases reported worldwide over a 60-year timeframe, it is important to comprehend the historical evolution of this entity. In 2018, we summarized the American history of PA, stressing the important early strides made by Bloodgood in 1904 with his many original observations of the "epulis form of ameloblastoma". During the preparation of our previous report, we were able to find several earlier and interesting descriptions in the literature. This review covers the early history of PA since the nineteenth century, chronologically focusing on meritorious articles published in the United States and Europe.

Abstract
Introduction When spinal fracture occurred in ankylosing spinal disorder (ASD) patients, it is important to evaluate not only the long lever arm but also bone density and bone quality for the determination of treatment strategies. This case-controlled study examined bone mineral density (BMD), bone metabolism markers, and pentosidine levels in patients with ASD. Methods Subjects with bridging of minimum four contiguous vertebral bodies were classified into ASD group and the rest into non-ASD group. The former was further divided into two subgroups based on the presence/absence of sacroiliac joint ankylosis (SJA). We compared BMD, bone metabolism markers, and pentosidine levels in these groups. Results The BMD T and Z scores of the femur proximal extremity were lower in the ASD with SJA group than those in the ASD without SJA group. When groups were matched for age, weight, and eGFR, compared with the non-ASD group, the ASD with SJA group had lower BMD of the lumbar spine and femur proximal extremity and the ASD without SJA group had significantly higher BMDs of the lumbar spine and femur proximal extremity. After matching, the ASD without SJA group showed a significantly higher pentosidine level than the non-ASD group. Conclusions Patients with SJA have low femur proximal extremity BMD, whereas those with ASD without SJA have a higher BMD of the femur proximal extremity with high pentosidine level. Investigating the presence or absence of SJA is important for the determination of treatment strategies in fractured ASD patients.

Abstract
Objective Liver injury is a notable complication of coronavirus disease 2019 (COVID-19). This study aimed to clarify the clinical features and liver injury in Japanese patients with COVID-19. Methods We conducted a multicenter retrospective cohort study. All consecutive patients with COVID-19 who visited or were admitted to our hospital before May 12, 2020, were enrolled. Their demographics, symptoms, laboratory findings, comorbidities, concomitant drugs, treatment, and clinical course were reviewed. We defined liver injury as alanine aminotransferase (ALT) or gamma-glutamyl transferase (GGT) levels over the upper limit of normal. Results Twenty-two patients with COVID-19 (median age, 47 years old; men/women, 13/9) were enrolled. Two patients had underlying liver diseases, and two were diagnosed as having COVID-19 without any symptoms. Elevated ALT and GGT levels were found in 12 and 12 patients, respectively, and liver injury was observed in 15 patients (68.2%). Compared with the patients without liver injury, those with liver injury had a significantly higher fever during the clinical course (median, 37.5°C vs. 38.8°C, p=0.006). A significant correlation was found between the highest serum liver values and the highest body temperature in each patient. Among the 22 patients, 4 required artificial respiratory support, and 2 died thereafter. Liver injury was not associated with the severity or mortality of COVID-19. Conclusion Elevated levels of liver enzymes in the Japanese patients with COVID-19 were associated with the highest body temperature during the clinical course but not with the severity or mortality of COVID-19.

Abstract
BACKGROUND/PURPOSE Although ursodeoxycholic acid (UDCA) is a first-line treatment for primary biliary cholangitis (PBC), 20%-30% of patients with PBC exhibit an incomplete response to UDCA. Recently, the UDCA Response Score was proposed for predicting response to UDCA using pretreatment parameters in patients with PBC. We aimed to validate the UDCA Response Score in Japanese patients with PBC. METHODS Registry data of Japanese patients (n = 873) were collected. Patients with data on all clinical parameters required for calculating the UDCA Response Score were selected. The endpoint was UDCA response, defined as alkaline phosphatase <1.67 times the upper limit of the normal value after 12 months of UDCA treatment. RESULTS All parameters were available in 804 patients (male/female = 120/684, age 58.9 [interquartile range 51.1-66.9] years). Bezafibrate was commenced within 12 months of UDCA in 78 patients (9.7%) because of the lack of an early response. We found that the endpoint was not reached in these 78 patients, and the area under the receiver operating characteristic curve (AUROC) of the score was 0.74 (95% confidence interval [CI] 0.70-0.79). The AUROC was 0.77 (95% CI 0.70-0.83) in patients undergoing UDCA monotherapy (n = 726). Finally, the AUROC of the modified UDCA Response Score using only data from the treatment start date was 0.80 (95% CI 0.70-0.90) in patients receiving a combination therapy of UDCA and bezafibrate (n = 160). CONCLUSION The validity of the UDCA Response Score was acceptable in Japanese patients; this score will be informative in patients treated with a combination therapy of UDCA and bezafibrate.

Abstract
Background:Many blood vessels are generated in the hyperplastic synovial tissue of patients with rheumatoid arthritis (RA), and lead to chronic tissue inflammation and joint destruction [1]. Janus kinase (JAK) family consisting of JAK1, JAK2, JAK3 and tyrosine kinase 2 (TYK2) are chain receptors which phosphorylate signal transducers and activators of transcription (STAT) and mediate inflammatory diseases including RA [2]. Nowadays, several JAK inhibitors such as Tofacitinib (TOF), Baricitinib (BAR) and Peficitinib (PEF) have been developed and demonstrated to have the inhibitory effects on inflammatory arthritis [3-5]. However, there were few reports concerning their effects on angiogenesis in vitro.Objectives:The purpose of the present study is to investigate the influence of JAK inhibitors on angiogenesis of human umbilical vein endothelial cell (HUVEC) activated by vascular endothelial growth factor (VEGF).Methods:The cell line of HUVECs were used for this study. The activity of proliferation and tube formation were analyzed by counting assay and tube formation assay, respectively.In counting assay, HUVECs (5 × 104cells/ml) were seeded onto 96-well cell culture plate with 20 ng/ml VEGF including various doses (0.1µM, 1µM, 5µM) of TOF, BAR or PEF. After 48 hours incubation at 37°C in a humidified atmosphere containing 5% CO2, cell proliferation of each groups was assessed using cell counting kit. In tube formation assay, HUVECs (5 × 104cells/ml) were treated with 20ng/ml VEGF including various dose (0.1µM, 1µM, 5µM) of TOF, BAR or PEF for 00 hours, then seeded onto 48-well plate applied with Matrigel. After 24 hours incubation on Matrigel, the capillary-like tube formation of each well was photographed using phase contrast microscopy. Tube formation were quantitated by measurement of the length of branch.Results:HUVECs were activated in proliferation and tube formation by VEGF treatment. And, the proliferation and tube formation of HUVECs activated by VEGF were suppressed by All of TOF, BAR and PEF. In particular, TOF and PEF could suppress them highly.Conclusion:This study showed the inhibitory effect of JAK inhibitors on proliferation and tube formation of HUVECs activated by VEGF. In particular, the angiogenesis of HUVECs activated by VEGF was highly suppressed by TOF and PEF. VEGF is reported to regulate the angiogenesis through multi JAK-STAT signaling pathways [6]. The inhibitory effects on angiogenesis of TOF, BAR and PEF might depend on the differences in their affinity for JAKs. VEGF has been shown to a have a central involvement in the angiogenic process in RA [7]. JAK inhibitors might suppress the angiogenesis in RA synovial tissues by inhibiting VEGF signaling.References:[1]Scott DL, et al. Rheumatoid arthritis. Lancet. 2010.[2]Banerjee S, et al.

Abstract
Background:Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by hyperplasia of synovial tissues [1]. Tumor necrosis factor (TNF)-α is one of the pro-inflammatory cytokines that play a crucial role in the pathogenesis of RA synovitis, and TNF inhibitors (TNFi) were reported to force the RA to go into remission or low disease activity and have brought revolutionary impacts on RA treatment [2]. TNFi have been shown to act on inflammatory cells and form the discoid fibrosis in the sublining layers [3,4]. However, the changes of synovial tissue and the cause of discoid fibrosis in RA patients treated with TNFi has not been determined in detail.Objectives:The purpose of this study is to demonstrate the histological changes and the types of cells around discoid fibrosis in RA synovium treated with TNFi.Methods:Synovial tissues were obtained from 30 patients with RA during joint surgeries. 6 patients were treated with TNFi (1 patient with golimumab, 3 patients with etanercept, 2 patients with infliximab). As a control, synovial tissues were obtained from 6 patients who were treated only with csDMARDs (6 patients with MTX). The frozen sections were stained by hematoxylin and eosin (HE). To detect the apoptosis, TdT-mediated dUTP nick end labeling (TUNEL) was performed. The immunohistochemical characterization of the synovial cells was performed by using following antibodies: CD20 and CD3 for detecting B and T lymphocytes respectively, CD163 and CD86 for detecting M1 and M2 macrophage respectively.Results:In the sections stained with HE, the formation of discoid fibrosis and the other characteristic changes including hydropic degeneration, vacuolation, sclerosis of small vasculature, and the number of multilayered synovial cells was decreased in synovium from RA patients treated with TNFi. In the sections with TUNEL stain, apoptosis of lining cells around the discoid fibrosis was detected in RA synovium treated with TNFi (Figure 1a, 1b). In the sections with immunohistochemistry stain, CD86 expression increased in lining layer of RA synovium treated with TNFi. CD163 positive cells showed diffuse expression in RA synovium treated with TNFi. In contrast, CD20 and CD3 positive cells decreased around discoid fibrosis compared to control sections. These results showed indicated that the types of cells in lining and sublining layers were mainly macrophages and that the apoptosis of macrophages might form the discoid fibrosis in lining layers.Conclusion:This study showed the apoptosis of lining cells derived from macrophages resulted in the formation of the discoid fibrosis. These findings indicated TNFi might induce apoptosis of macrophage leading to the suppression of RA synovitis.References:[1] Scott Dl, et al.

Abstract
Background: Chronic invasive form of fungal rhinosinusitis (FRS) is characterized by the invasion of fungal organisms into the sinonasal mucosa in the background of diabetes mellitus and corticosteroid treatment. Although the histopathology has traditionally been used to make a proven diagnosis of invasive fungal infections, the dependence on tissue samples and the slow turnaround time hamper the early confirmation of such infections. Methodology: This is a retrospective case series conducted over 6 years. All patients with a chronic course and immunosuppressive background of FRS diagnosed by radiologic imaging and treated with endoscopic sinus surgery were eligible for inclusion. Data were collected through medical records, including basic characteristics, symptoms and signs, imaging findings, laboratory investigations, pathology, treatment, and outcomes. Results: Fifteen patients with chronic course and immunosuppressive background of FRS diagnosed by radiologic imaging were identified. High values of 1,3-b-D-glucan (BDG) assay were recognized in 5 patients, whereas the other 10 patients with negative findings in the BDG assay showed sinus mycetomas. All the 5 patients showing significant elevations of serum BDG showed positive findings in the polymerase chain reaction (PCR), but only 2 patients were positive in the histopathology. The findings of the BDG assay were consistent with those of the PCR method, which was superior in sensitivity to the histopathology. Conclusion: We first applied BDG assay as a diagnostic tool for chronic invasive FRS. The BDG assay may be useful to distinguish chronic invasive FRS, including its early stage, from noninvasive mycetoma, contributing to timely treatment.

Abstract
AIM Detection of coagulase-negative Staphylococcus in blood culture may be a result of either bacteremia or contamination. This often leads to diagnostic uncertainly. Our objective was to develop a method for differentiating whether a coagulase-negative Staphylococcus sp. positive blood culture represents bacteremia or contamination based on positive bottle detection pattern and time to positivity (TTP). METHODS This study included 155 and 51 adults with positive blood cultures for Staphylococcus epidermidis and Staphylococcus hominis, respectively, over a three-year period from 2016 to 2018. Positive blood culture cases were categorized as either bacteremia or contamination based on the clinically available information, and the detection pattern and TTP in each category were investigated. RESULTS A total of 57, 92, and 6 S. epidermidis positive blood cultures were categorized as bacteremia, contamination, and undetermined, respectively, whereas 15 and 36 S. hominis positive blood cultures were categorized as bacteremia and contamination, respectively. For positive blood cultures categorized as bacteremia, all four bottles in two sets of blood cultures were positive in 47/47 S. epidermidis and 14/14 S. hominis, respectively, whereas either one bottle in each of two sets or three bottles in two sets were positive in 10/19 S. epidermidis and 1/4 S. hominis, respectively; most of those TTPs were <48 h. Among them, the TTP in catheter-related blood stream infection was <24 h. CONCLUSION Although clinical assessment is crucial to differentiate between bacteremia and contamination, a combination of positive bottle detection pattern and TTP is a valuable diagnostic auxiliary tool.

Abstract
Background Non-alcoholic fatty liver disease (NAFLD) is a hepatic manifestation of metabolic syndrome. Within the spectrum of NAFLD, non-alcoholic steatohepatitis (NASH) in combination with hepatic inflammation and fibrosis can lead to liver cirrhosis and hepatocellular carcinoma. Dysbiosis was reported to contribute to NASH pathogenesis. This study aimed to determine the effects of fructo-oligosaccharides (FOS) on steatohepatitis and visceral adiposity in an obese mouse model of NASH. Methods Twelve newborn C57BL/6 J male mice were subcutaneously injected with monosodium glutamate (MSG) to induce obesity on a conventional diet. Six mice were also administered 5% FOS via drinking water from 10 weeks of age. At 18 weeks, histological characteristics of the liver and epididymal fat were compared between the groups. Hepatic mRNA expression of lipid metabolism enzymes and SCFA in feces and sera were measured. Results Hepatic steatosis, inflammatory cell infiltration, and hepatocyte ballooning in the liver and increased hepatic mRNA expression of fatty acid synthase and glycerol-3-phosphate acyltransferase were observed in the MSG-treated mice. FOS treatment improved the liver pathology and blunted the increases in the mRNA expression levels of lipid metabolism enzymes. In addition, FOS inhibited adipocyte enlargement and formation of crown-like structures and reduced the M1 macrophage frequency in the epididymal fat of the MSG mice (39.4% ± 3.0% vs. 22.8% ± 0.7%; P = 0.001). FOS increased not only the fecal concentrations of n-butyric acid (0.04 ± 0.01 vs. 0.38 ± 0.14 mg/g, P = 0.02), propionic acid (0.09 ± 0.03 vs. 0.42 ± 0.16 mg/g, P = 0.02), and acetic acid (0.65 ± 0.16 vs. 1.48 ± 0.29 mg/g, P = 0.03) but also the serum concentration of propionic acid (3.9 ± 0.5 vs. 8.2 ± 0.5 μmol/L, P = 0.001). Conclusions FOS ameliorates steatohepatitis, visceral adiposity, and chronic inflammation by increasing SCFA production.

Abstract
Porcine immature oocytes can survive vitrification at high rates and retain their ability to undergo maturation and fertilization; however, the procedure reduces their competence for subsequent embryo development via unknown mechanisms (Somfai et al. 2014 Plos One 9, e97731). The aim of the present study was to clarify whether our vitrification procedure at the germinal vesicle stage triggers apoptosis in oocytes and subsequent developing embryos. Immature porcine cumulus-oocyte complexes obtained from slaughterhouse-derived ovaries were vitrified and warmed by our method (Appeltant et al. 2018 Cryobiology 85, 87-94) immediately after collection (vitrified group). The oocytes were equilibrated in 2% (vol/vol) ethylene glycol and 2% (vol/vol) propylene glycol for 13-15min. Then, they were vitrified by dropping them into liquid nitrogen in 2-μL microdrops of a medium composed of 17.5% ethylene glycol, 17.5% propylene glycol, 0.3M sucrose, and 50mgmL−1 polyvinylpyrrolidone. After warming, they were subjected to IVM, fertilization (IVF), and embryo culture using chemically defined media (Yoshioka et al. 2008 J. Reprod. Dev. 54, 208-213). From each collected batch, a group of oocytes was processed without vitrification (control group). Apoptosis was assayed in membrane-intact oocytes at the end of IVM and in cleavage-stage embryos on Day 2 after IVF (Day 0) by the CaspACE FITC-VAD-FMK In Situ Caspase Marker (Promega; Experiment 1), deoxynucleotidyl transferase (TdT) dUTP nick-end labelling (TUNEL; Experiment 2), and analysis of mRNA levels by RT-qPCR for the pro-apoptotic Bax and CASP3 genes (Experiment 3). Each experiment was replicated three times. Data were analysed by Kruskal-Wallis test followed by Dunn's multiple comparisons test. The mean survival rate of vitrified oocytes was 89.2%. There was no significant difference between the control and vitrified groups in relative caspase levels in IVM oocytes and in 2- to 4-cell embryos after IVF; however, significantly increased caspase activity (P<0.05) was detected in oocytes and embryos after treatment with 10 μM staurosporine (positive control). There was no significant difference between the control and vitrified groups in the proportion of TUNEL-positive oocytes (4.1 and 0.8%, respectively) and embryos (0 and 0%, respectively), whereas 96.6% of oocytes and 100% of cleavage stage embryos treated with 1000IUmL−1 deoxyribonuclease I (positive control) were proven to be TUNEL positive (P<0.05). Similar mRNA levels for Bax and CASP3 genes were detected in oocytes at the end of IVM and subsequent developing 4- to 8-cell embryos between the control and vitrified groups. In conclusion, vitrification of porcine oocytes at the germinal vesicle stage by our method did not trigger apoptosis in oocytes and subsequent developing embryos.

Abstract
A 70-year-old woman was referred to our hospital due to symptoms of dry eyes, dry mouth, and epigastric pain. Computed tomography showed distal pancreatic swelling, liver edge dullness and surface irregularities. Serum anti-nuclear antibody titers, immunoglobulin G and IgG4 levels were elevated. Autoimmune pancreatitis (AIP) was diagnosed based on endoscopic findings and a histopathological examination. Her AIP improved after starting prednisolone treatment. A liver biopsy revealed interface hepatitis with lymphoplasmacyte and IgG4-positive plasma cell infiltration. In addition, non-alcoholic steatohepatitis (NASH) was diagnosed based on the presence of parenchymal steatosis, ballooning hepatocytes, and pericellular fibrosis. We experienced a unique liver disease case showing IgG4-related liver disease overlapping with NASH.
