Abstract
OBJECTIVES Patients with malignant wounds suffer from physical and psychological symptom burden. Despite psychological support being required, the impact of malignant wounds on patients' psychological distress is poorly investigated. We evaluated psychological distress associated with malignant wounds for patients at their end of life. METHODS This study used the secondary analysis of the results of a large prospective cohort study, which investigated the dying process among patients with advanced cancer in 23 palliative care units in Japan. The primary outcome of this study was the prevalence of moderate to severe psychological symptom burden, evaluated by the Integrated Palliative Care Outcome Scale (IPOS)-feeling at peace scores of 2-4. In addition, the factors affecting psychological symptoms were investigated. The quality of death was also evaluated upon death using the Good Death Scale score. RESULTS Out of the total 1896 patients, 156 had malignant wounds (8.2%). Malignant wounds were more common in female and young people. The breast, head, and neck were the most prevalent primary sites. More patients with malignant wounds had IPOS-feeling at peace scores of 2-4 than patients without malignant wounds (41.0% vs. 31.3%, p = 0.024). Furthermore, psychological distress was associated with moderate to severe IPOS-pain and the frequency of dressing changes. The presence of malignant wounds did not affect the quality of death. SIGNIFICANCE OF RESULTS This study showed increased psychological distress due to malignant wounds. Patients with malignant wounds require psychological support in addition to the treatment of physical symptoms for maintaining their quality of life.

Abstract
BACKGROUND This study sought to investigate the symptoms and prognoses of patients with breast cancer and malignant wounds in the palliative care unit setting. METHODS This study was a sub-group analysis of a multicenter, prospective, observational study. Patients admitted to 23 palliative care units in Japan between January and December 2017 were enrolled. Data of patients with breast cancer were extracted. We compared demographic characteristics, symptoms, and prognoses by breast cancer malignant wound status. The primary outcome was overall survival. Secondary outcomes included Palliative Prognostic Index (PPI) score, malignant wound characteristics, and symptom burden. RESULTS Of 1896 patients, 131 (6.9%) had breast cancer. In this cohort, 44 (33.6%) patients had malignant wounds. Most malignant wounds (88%) were on the back and chest. Malignant wounds were associated with skin redness, erosion, necrosis, or fistula. Symptoms included bleeding, exudate, odor, and pain. Twenty-eight patients (63.6%) needed dressing changes and 14 (31.8%) patients experienced bleeding. None died due to bleeding. In the malignant wounds group, 32 (72.8%) patients had used an opioid dose equivalent to 38 mg of oral morphine daily, compared to 25 mg by 57 (65.5%) patients in the non-malignant wounds group (P = .26). Median PPI scores at hospital admission were 4.5 vs 6.5 (P = .08). Median survival was 23 vs 21 days (P = .48). CONCLUSIONS Patients with malignant wounds had a distinct symptom burden profile and tended to use a higher dose of opioids. The effect of malignant wounds on survival was unclear.

Abstract
Abstract
Background
Therapeutic angiogenesis mediated by stem/progenitor cells is an attractive therapeutic option against cardiovascular disease (CVD). Adipose tissue (AT) can be safely obtained even in CVD patients with anti-platelet medications, and it is a readily available source of culture-expanded adipose-derived stem cells (ADSCs) for transplantation. Single-cell transcriptome enables us to screen all the surface markers at once, while conventional strategies have been limited for the number of target markers. Furthermore, gene profiling at single-cell resolution can be used for the quantification of each marker by how many favorable cells can be purified without mixing of detrimental cells.
Purpose
We aimed to identify and characterize a cell population with in vivo angiogenic potential by single-cell RNA sequencing (scRNA-seq) analysis and xenograft experiments.
Methods
We revisited scRNA-seq datasets of single cell fraction from AT, bone-marrow (BM), and umbilical-cord blood (UCB, n=6/organ) to find cell populations with pro-angiogenic potential. Next, we collected AT from CVD patients (n=23) and used multicolor flow cytometry to quantify and sort the specific populations. PBS, the specific marker-negative and unsorted ADSCs were used as controls. Xenograft models of PKH26 pre-labeled human ADSC transplantation in limb ischemia were used to evaluate the lectin capillary density, PKH+ engrafted ADSCs, and blood flow recovery.
Results
Clustering divided CD45–CD31–CD34+ progenitor fraction into 3 clusters. We identified pro-/anti-angiogenic clusters based on the expressions of well-known pro-/anti-angiogenic factors. All genes encoding cell-surface proteins were compared in this functional clustering, resulted in 17 markers screened (Fig. 1A, B). Taken together with enrichment analysis, CD271+ cells showed predominant and pro-angiogenic gene profile from the other top candidates including CD36 and CD54 (Fig. 1C, D). Next, we evaluated the number and gene profile of CD271+ cells in well-known stem cell sources including BM and UCB. Surprisingly, the number of CD271 expressing cells were significantly lower and did not show angiogenic gene profile in BM and UCB (Fig. 2A). In analysis of AT from 23 CVD patients, CD271+ cells were significantly decreased by donor insulin resistance (Fig. 2B). Cell therapy using CD271+ ADSCs demonstrated in vivo angiogenic capacity compared to those of CD271– ADSCs and PBS in limb ischemia model. Furthermore, CD271+ ADSC transplantation showed enhanced efficacy compared to unsorted ADSCs from the same donors (Fig. 2C–E).
Conclusion
In this study, we identified CD271+ cell population in AT as an angiogenic cell population through scRNA-seq analysis and cell therapy experiments. AT obtained from donors without insulin resistance would be the most suitable for CD271+ ADSC isolation. CD271+ ADSC transplantation with a promising angiogenic capacity could contribute better cell-based therapy tackling CVD.

Abstract
Abstract
Background: Most of CRC were well or moderately differentiated adenocarcinoma and P-ad-ca is very rare. In Japan, P-ad-ca was reported to be only 4-6% of all CRC. NEC is also rare. The incidence of that were reported to be less than 1%. One of their points of common is morphological poorly differentiated appearance. In this study, we evaluated the incidence of NEC contaminated in the CRC given a confirmed diagnosis as P-ad-ca.
Material and Method: From 2009 to 2019, 816 CRCs were resected in department of Yokohama City University Hospital and 74 cases showing P-ad-ca or having a small region of P-ad-ca with well or moderately differentiated ad-ca (W-ad-ca, M-ad-ca). Among the 74 cases, there were 8 of P-ad-ca, 4 of W-ad-ca with P-ad-ca, 44 of M-ad-ca with P-ad-ca, and 18 W-ad-ca and M-ad-ca with P-ad-ca. Immunohistochemistry (IHC) using neuroendocrine markers (NM) including chromogranin A, synaptophysin and insulinoma-associated protein 1 (INSM1) was performed to identified NEC. Recently, a high incidence of Rb protein loss was reported in NEC of several organs, then IHC using Rb monoclonal antibody was also performed. The cancers showing immunohistochemically positive of at least one of the three NM and negative of Rb were identified as true NEC in this study.
Results: At least one of the three NM was positive in the 39 cases. In these 39 cases, 3 cases were also Rb negative. Two of the three cases were region of P-ad-ca. These 2 P-ad-ca regions showed positive of NM. Interestingly, in the other one case, region of W-ad-ca showed positive of NM and negative of Rb. Region of P-ad-ca of the case showed positive of all three NM and Rb. From morphological appearance, this case was quite unlikely to true NEC.
Conclusion: In 74 P-ad-ca, 2 cases might be true NEC in our small evaluation. NEC might be contaminated in the P-ad-ca of CRC which is difficult to be distinguished by only pathological findings of HE staining.

Abstract
Neuroendocrine carcinoma (NEC) is a rare subtype of malignant gallbladder tumor. Although surgical resection is the only potentially curative therapy for gallbladder NEC, most cases are surgically unresectable because of advanced stage disease and/or biologically aggressive behavior. The standard palliative treatment for malignant gallbladder tumors is chemotherapy; however, the efficacy of chemoradiotherapy in the treatment of gallbladder tumors is controversial. Here, we report a case of gallbladder NEC that showed a durable response to chemoradiotherapy. A 68-year-old Japanese man presented with a huge gallbladder tumor with liver and duodenal invasion. Pathological findings revealed poorly differentiated NEC of the gallbladder. After seven cycles of chemotherapy comprising cisplatin and irinotecan, computed tomography (CT) revealed remarkable tumor shrinkage, but an enlarged portal lymph node. The patient was treated with 50.4 Gy in 28 fractions with two cycles of cisplatin and etoposide. After chemoradiotherapy, the enlarged lymph node also decreased in size. Maximum standardized uptake value of fluorodeoxyglucose-positron emission tomography/CT(FDG-PET/CT) changed from 8.2 to physiological accumulation. We defined this condition as a complete response on both enhanced CT and FDG-PET/CT; therefore, we did not perform systemic treatment and only observed his condition. This patient remained healthy with no recurrence at 3 years after chemoradiotherapy.

Abstract
Platelet-neutrophil aggregates (PNAs) facilitate neutrophil activation and migration and could underpin the recruitment of neutrophils to the pancreas during type 1 diabetes (T1D) pathogenesis. PNAs, measured by flow cytometry, were significantly elevated in the circulation of autoantibody-positive (Aab+) children and new-onset T1D children, as well as in pre-T1D (at 4 weeks and 10–12 weeks) and T1D-onset NOD mice, compared with relevant controls, and PNAs were characterized by activated P-selectin+ platelets. PNAs were similarly increased in pre-T1D and T1D-onset NOD isolated islets/insulitis, and immunofluorescence staining revealed increased islet-associated neutrophil extracellular trap (NET) products (myeloperoxidase [MPO] and citrullinated histones [CitH3]) in NOD pancreata. In vitro, cell-free histones and NETs induced islet cell damage, which was prevented by the small polyanionic drug methyl cellobiose sulfate (mCBS) that binds to histones and neutralizes their pathological effects. Elevated circulating PNAs could, therefore, act as an innate immune and pathogenic biomarker of T1D autoimmunity. Platelet hyperreactivity within PNAs appears to represent a previously unrecognized hematological abnormality that precedes T1D onset. In summary, PNAs could contribute to the pathogenesis of T1D and potentially function as a pre-T1D diagnostic.

Abstract
BACKGROUND AND PURPOSE The hemodynamics associated with cerebral AVMs have a significant impact on their clinical presentation. This study aimed to evaluate the hemodynamic features of AVMs using 3D phase-contrast MR imaging with dual velocity-encodings. MATERIALS AND METHODS Thirty-two patients with supratentorial AVMs who had not received any previous treatment and had undergone 3D phase-contrast MR imaging were included in this study. The nidus diameter and volume were measured for classification of AVMs (small, medium, or large). Flow parameters measured included apparent AVM inflow, AVM inflow index, apparent AVM outflow, AVM outflow index, and the apparent AVM inflow-to-outflow ratio. Correlation coefficients between the nidus volume and each flow were calculated. The flow parameters between small and other AVMs as well as between nonhemorrhagic and hemorrhagic AVMs were compared. RESULTS Patients were divided into hemorrhagic (n = 8) and nonhemorrhagic (n = 24) groups. The correlation coefficient between the nidus volume and the apparent AVM inflow and outflow was .83. The apparent AVM inflow and outflow in small AVMs were significantly smaller than in medium AVMs (P < .001 for both groups). The apparent AVM inflow-to-outflow ratio was significantly larger in the hemorrhagic AVMs than in the nonhemorrhagic AVMs (P = .02). CONCLUSIONS The apparent AVM inflow-to-outflow ratio was the only significant parameter that differed between nonhemorrhagic and hemorrhagic AVMs, suggesting that a poor drainage system may increase AVM pressure, potentially causing cerebral hemorrhage.

Abstract
BACKGROUND Constipation is a common, distressing complication in patients with cancer receiving palliative care. Elobixibat is a novel inhibitor of the ileal bile acid transporter that is used to treat chronic constipation by stimulating bowel function. However, its efficacy in patients with cancer has not been examined. This study investigated the drug's effectiveness in patients with cancer with chronic constipation. PATIENTS AND METHODS This prospective-sampling, single-center, observational study included hospitalized patients with cancer diagnosed, using the Rome IV criteria, with chronic constipation. Within 2 weeks of hospitalization, each participant was administered elobixibat (5-15 mg) daily until discharge. Spontaneous bowel movements (SBMs), complete spontaneous bowel movements (CSBMs), Bristol stool form scale (BSFS) scores, and the Patient Assessment of Constipation Quality of Life questionnaire (PAC-QOL) scores were assessed before and after elobixibat administration. We also evaluated the relationship between the amount of food consumed and the SBM frequency. RESULTS Among the 83 participants, the mean pre- and post-treatment frequencies of daily SBMs were 0.3 and 1.2 (p < .0001) and those of CSBMs were 0.1 and 0.6 (p < .0001), respectively. The mean pretreatment BSFS score was 1.6, whereas the post-treatment value was 3.5 (p < .0001); the mean PAC-QOL score (overall) improved from 1.01 to 0.74 (p = .01). There was no significant change in the daily SBM frequency between fasting and feeding states (1.2 vs. 1.3; p = .8), and there was no correlation between the amount of food intake and the SBM frequency after elobixibat administration (r = .03). Serious adverse events were not observed. CONCLUSION This study showed that elobixibat is safe and effective for patients with cancer with chronic constipation, regardless of the food intake amount. IMPLICATIONS FOR PRACTICE Elobixibat was effective at relieving chronic constipation in patients with various cancers. Serious adverse events were not observed, and the relief of constipation was independent of variation in food intake.

Abstract
Band-gap engineering is one of the fundamental techniques in semiconductor technology and also applicable in next generation spintronics using the spin degree of freedom. To fully utilize the spintronic materials, it is essential to optimize the spin-dependent electronic structures in the operando conditions by applying magnetic and/or electric fields. Here we present an advanced spectroscopic technique to probe the spin-polarized electronic structures by using magnetic circular dichroism (MCD) in resonant inelastic soft X-ray scattering (RIXS) under an external magnetic field. Thanks to the spin-selective dipole-allowed transitions in RIXS-MCD, we have successfully demonstrated the direct evidence of the perfectly spin-polarized electronic structures for the prototypical halfmetallic Heusller alloy \documentclass[12pt]{minimal}

Abstract
Purpose Peptide receptor radionuclide therapy (PRRT) with 177Lu-DOTA0-Tyr3-octreotate (177Lu-DOTATATE) is one of the most reliable treatments for unresectable, progressive neuroendocrine tumors (NETs) with somatostatin receptor expression. We have, for the first time, reported the results of the tolerability, safety, pharmacokinetics, dosimetry, and efficacy of this treatment for Japanese patients with NET. Methods Patients with unresectable, somatostatin receptor scintigraphy (SRS)-positive NETs were enrolled in this phase I clinical trial. They were treated with 29.6 GBq of 177Lu-DOTATATE (four doses of 7.4 GBq) combined with amino acid solution infusion plus octreotide long-acting release (LAR) 30 mg. The primary objective of this study was to evaluate the tolerability, safety, pharmacokinetics, and dosimetry of a single administration of this treatment in patients with SRS-positive NETs. Results Six Japanese patients (three men and three women; mean age 61.5 years; range 50–70 years) with SRS-positive unresectable NETs were recruited. 177Lu-DOTATATE was eliminated from the blood in a two-phase manner. Cumulative urinary excretion of radioactivity was 60.1% (range 49.0%–69.8%) within the initial 6 h. The cumulative renal absorbed dose for 29.6 GBq of 177Lu-DOTATATE was 16.8 Gy (range 12.0–21.2 Gy), and the biological effective dose was 17.0 Gy (range 12.2–21.5 Gy). Administration of 177Lu-DOTATATE was well tolerated, with no dose-limiting toxicities. Grade 3 lymphopenia occurred in two (33.3%) cases, but there were no other severe toxicities. Four patients achieved partial response (objective response rate, 66.7%), one patient had stable disease, and one patient had progressive disease. Conclusion PRRT with 177Lu-DOTATATE was well-tolerated and showed good outcomes in Japanese patients with unresectable NETs. Peptide receptor radionuclide therapy, 177Lu-DOTA0-Tyr3-octreotate .

Abstract
Background Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogs is an innovative treatment for advanced somatostatin‐positive neuroendocrine tumors (NETs). PRRT cannot be performed in Japan because there is no approval or insurance cover so far. Methods We relied on foreign institutions to perform PRRT for Japanese patients with NETs. We retrospectively evaluated the safety and efficacy of PRRT. The inclusion criteria were pathologically confirmed well‐differentiated NET and visible tumor uptake on pre‐therapeutic somatostatin receptor scintigraphy. 177Lu‐DOTA‐TOC was used as the standard treatment, and patients received three infusions every 8 weeks. Until the end of 2017, combination treatment with 90Y and 177Lu‐DOTA‐TOC was performed using the same protocol. Results Thirty‐five patients were evaluated, and the primary lesions were pancreas, rectum, small intestine, stomach, and other locations. The partial response rate was 42.9%. Progression‐free survival (PFS) was 12.8 months and overall survival was 42.8 months. There was no significant difference in PFS between front‐line and late‐line PRRT (11.0 months vs 28.0 months; P = .383). Severe adverse events included lymphocytopenia (20.0%) and thrombocytopenia (5.7%). Myelodysplastic syndrome occurred in one case. Conclusion PRRT was effective and safe for Japanese patients with advanced NETs. PRRT was equally effective as front‐line and late‐line treatment.

Abstract
Extrapulmonary neuroendocrine carcinoma (EPNEC) is a lethal disease with a poor prognosis. Platinum-based chemotherapy is used as the standard first-line treatment for unresectable EPNEC. Several retrospective studies have reported the results of the utilization of temozolomide (TMZ) as a drug for the second-line treatment for EPNEC. Patients with unresectable EPNEC that were resistant to platinum-based combination chemotherapy were recruited for a prospective phase II study of TMZ monotherapy. A 200 mg/m2 dose of TMZ was given from day 1 to day 5, every 4 weeks. Response rate (RR) was evaluated as the primary end-point. The presence of O6 -methylguanine DNA methyltransferase (MGMT) in EPNEC patients was also evaluated as exploratory research. Thirteen patients were enrolled in this study. Primary lesions were pancreas (n = 3), stomach (n = 3), duodenum (n = 1), colon (n = 1), gallbladder (n = 1), liver (n = 1), uterus (n = 1), bladder (n = 1), and primary unknown (n = 1). Each case was defined as pathological poorly differentiated neuroendocrine carcinoma from surgically resected and/or biopsied specimens. The median Ki-67 labeling index was 60% (range, 22%-90%). The RR was 15.4%, progression-free survival was 1.8 months (95% confidence interval [CI], 1.0-2.7), overall survival (OS) was 7.8 months (95% CI, 6.0-9.5), and OS from first-line treatment was 19.2 months (95% CI, 15.1-23.3). No grade 3 or 4 hematological toxicity had occurred and there was one case of grade 3 nausea. One case presented MGMT deficiency and this case showed partial response. Temozolomide monotherapy is a feasible, modestly effective, and safe treatment for patients with unresectable EPNEC following platinum-based chemotherapy, especially those with MGMT deficiency.

Abstract
BACKGROUND Laparoscopic liver resection for hepatocellular carcinoma (HCC) in Child-Pugh A cirrhosis has been demonstrated as beneficial. However, the role of laparoscopy in Child-Pugh B cirrhosis is undetermined. The aim of this retrospective cohort study was to compare open and laparoscopic resection for HCC with Child-Pugh B cirrhosis. METHODS Data on liver resections were gathered from 17 centres. A 1 : 1 propensity score matching was performed according to 17 predefined variables. RESULTS Of 382 available liver resections, 100 laparoscopic and 100 open resections were matched and analysed. The 90-day postoperative mortality rate was similar in open and laparoscopic groups (4.0 versus 2.0 per cent respectively; P = 0.687). Laparoscopy was associated with lower blood loss (median 110 ml versus 400 ml in the open group; P = 0.004), less morbidity (38.0 versus 51.0 per cent respectively; P = 0.041) and fewer major complications (7.0 versus 21.0 per cent; P = 0.010), and ascites was lower on postoperative days 1, 3 and 5. For laparoscopic resections, patients with portal hypertension developed more complications than those without (26 versus 12 per cent respectively; P = 0.002), and patients with a Child-Pugh B9 score had higher morbidity rates than those with B8 and B7 (7 of 8, 10 of 16 and 21 of 76 respectively; P < 0.001). Median hospital stay was 7.5 (range 2-243) days for laparoscopic liver resection and 18 (3-104) days for the open approach (P = 0.058). The 5-year overall survival rate was 47 per cent for open and 65 per cent for laparoscopic resection (P = 0.142). The 5-year disease-free survival rate was 32 and 37 per cent respectively (P = 0.742). CONCLUSION Patients without preoperative portal hypertension and Child-Pugh B7 cirrhosis may benefit most from laparoscopic liver surgery.

Abstract
Abstract
Background
Cardiac allograft vasculopathy is a combination of the development of de novo plaque and the progression of donor-transmitted plaque.
Purpose
This study aimed to evaluate the development of de novo plaque and the progression of donor-transmitted plaque within 12-month after heart transplantation (HTx) using serial intravascular ultrasound (IVUS) and optical coherence tomography (OCT). The association between inflammatory cytokines and plaque progression was also examined.
Methods
We prospectively enrolled 40 recipients to conduct serial three-vessel IVUS and OCT analysis at 8-week and 12-month after HTx. De novo plaque was defined as having maximum intimal thickness (MIT) ≥0.5 mm at 12-month in the absence of donor-transmitted plaques (MIT ≥0.5 mm at 8-week). Serum cytokines were screened with a bead-based multiplex assay.
Results
A total of 13 de novo plaques (fibrous, n=10; fibroatheroma, n=3) were detected in eight recipients. Serum interleukin (IL)-31 at 8-week was associated with the development of de novo plaques (p=0.009). A total of 31 donor-transmitted plaques (fibrous, n=12; fibroatheroma, n=11; fibrocalcific, n=8) were detected in 17 recipients. Multiple regression analysis revealed that fibrous (p=0.026) and fibroatheroma (p=0.012) observed at 8-week were significantly associated with subsequent plaque progression within 12-month after HTx. ΔPlaque burden was significant higher in de novo plaque than donor-transmitted plaque (38.8% [29.6–41.2] versus 8.7% [1.3–13.6], p<0.001). The prevalence of macrophage accumulation was lower in de novo plaque than in donor-transmitted plaque (8% versus 52%, p=0.006). Serum IL-31 at 8-week was correlated with the progression of donor-transmitted plaque as well as de novo plaque (r=0.663, p=0.029) although other cytokines like IL-1β, IL-6, IL-17, and tissue necrotic factor alpha were not.
Conclusions
In de novo plaques, fibrous plaque was the most common and macrophage accumulation was rarely observed. In donor-transmitted plaque, fibrous and fibroatheroma were independent predictor for the subsequent plaque progression. Serum interleukin-31 surge at subacute phase may play pathogenic role in cardiac allograft vasculopathy.

Abstract
Modification of the gap at the Dirac point (DP) in axion antiferromagnetic topological insulator [Formula: see text] and its electronic and spin structure have been studied by angle- and spin-resolved photoemission spectroscopy (ARPES) under laser excitation at various temperatures (9-35 K), light polarizations and photon energies. We have distinguished both large (60-70 meV) and reduced ([Formula: see text]) gaps at the DP in the ARPES dispersions, which remain open above the Neél temperature ([Formula: see text]). We propose that the gap above [Formula: see text] remains open due to a short-range magnetic field generated by chiral spin fluctuations. Spin-resolved ARPES, XMCD and circular dichroism ARPES measurements show a surface ferromagnetic ordering for the "large gap" sample and apparently significantly reduced effective magnetic moment for the "reduced gap" sample. These observations can be explained by a shift of the Dirac cone (DC) state localization towards the second Mn layer due to structural disturbance and surface relaxation effects, where DC state is influenced by compensated opposite magnetic moments. As we have shown by means of ab-initio calculations surface structural modification can result in a significant modulation of the DP gap.

Abstract
Cryosurgery is a recognized method for the treatment of mucoceles in the oral cavity. In this study, cryosurgery was used for mucoceles at the lip or buccal mucosa, and the effect and the indication were evaluated clinically. The subjects were patients with a clinical diagnosis of mucocele on the lip or buccal mucosa and who chose cryosurgery after procedures for both surgical excision and cryosurgery for the lesion were explained. Cryosurgery was performed with a freezing device using liquid nitrogen without local anesthesia. Twenty-four patients chose cryosurgery, including seven preschool children. There were no serious adverse events during and after cryosurgery. Healing progress after cryosurgery was not affected by patient age, lesion size, or how long the patients had the lesion. Two cases later underwent surgical excision because cryosurgery was not successful. Twenty-three patients chose surgical excision, one case had a recurrence. The number of younger patients who chose cryosurgery was significantly higher than that who chose surgical excision. This study suggests that cryosurgery is effective for mucoceles of the lip or buccal mucosa and is a simple and safe treatment method, especially for preschool children.

Abstract
Abstract
Background
Appropriate pulmonary artery catheter (PAC) use may effectively decrease mortality in acute heart failure patients. The concept that the pulmonary artery catheter (PAC) is a valuable tool for hemodynamic monitoring when used in appropriately selected patients and by physicians trained well to interpret and apply the data correctly provided has not been evaluated adequately yet in acute heart failure patients with preserved ejection fraction (HFpEF).
Methods
The PERSUIT-HFpEF Registry is a prospective, observational, multicenter cohort study on prognosis of HFpEF in Japan. Patients hospitalized for heart failure (diagnosed by using Framingham criteria) who met both of the following criteria were enrolled: 1) a left ventricular ejection fraction of 50% or more as measured at the local site by echocardiography; 2) an elevated level of N terminal pro brain natriuretic peptide (NT proBNP) (400 pg per milliliter or more) or brain natriuretic peptide (BNP) (100 pg per milliliter or more). In the present study, we evaluated the impact of PAC on all-cause death of the patients with HFpEF. PAC use was left at the discretion of attending physicians.
Results
The PERSUIT-HFpEF Registry enrolled 486 patients (81±9 years, 259 females, mean follow-up duration 198±195 days). Of these, data of PAC usage was available in 434 patients. Patients were further stratified according to use of a PAC: PAC 153 patients vs. non-PAC 281 patients. Length of hospitalization was numerically shorter in the PAC group than in the non-PAC group [20.3±14.7 vs. 22.5±17.4 days, p=0.182]. Kaplan-Meier estimated 1-year all-cause death rate was significantly lower in the PAC group than in the non-PAC group (9.5% vs. 19.1%, p=0.019). PAC use was associated with significant risk reduction of all-cause death [hazard ratio (HR) 0.425, 95% confidence interval (CI), 0.203–0.890, p=0.023] in the crude analysis. The significant risk reduction still existed after multivariate adjustment including potential confounders [HR 0.427, 95% CI, 0.185–0.984, p=0.046]
Kaplan Meier analysis
Conclusions
In the real-world Asian registry data, PAC use was associated with the improved all-cause death rate, suggesting that the PAC might be a useful guidance tool for treatment of the patients with HFpEF.

Abstract
Abstract
Background
Hepatokine selenoprotein P (SeP) contributes to insulin resistance and hyperglycemia in patients with type 2 diabetes. Inhibition of SeP protects the heart from ischemia reperfusion injury and serum levels of SeP are elevated in patients with heart failure with reduced ejection fraction.
Objective
We investigated the role of SeP in the regulation of cardiac remodeling in response to pressure overload.
Methods and results
To examine the role of SeP in cardiac remodeling, transverse aortic constriction (TAC) was subjected to SeP knockout (KO) and wild-type (WT) mice for 2 weeks. Hepatic expression of SeP in WT was significantly increased by TAC. LV weight/tibial length (TL) was significantly smaller in SeP KO mice than in WT mice (6.75±0.24 vs 8.33±0.32, p<0.01). Lung weight/TL was significantly smaller in SeP KO than in WT mice (10.46±0.44 vs 16.38±1.12, p<0.05). TAC-induced cardiac upregulation of the fetal type genes, including atrial and brain natriuretic factors, was significantly attenuated in SeP KO compared to WT. Furthermore, azan staining revealed that there was significantly less interstitial fibrosis in hearts after TAC in SeP KO than in WT mice. To determine whether hepatic overexpression of SeP affects TAC-induced cardiac hypertrophy, a hydrodynamic injection method was used to generate mice that overexpress SeP mRNA in the liver. Hepatic overexpression of SeP in SeP KO mice lead to a significant increase in LV weight/TL and Lung weight/TL after TAC compared to that in other SeP KO mice.
Conclusions
These results suggest that cardiac pressure overload induced hepatic expression of SeP and the absence of endogenous SeP attenuated cardiac hypertrophy, dysfunction and fibrosis in response to pressure overload in mice. SeP possibly plays a maladaptive role against progression of heart failure through the liver-heart axis.

Abstract
Abstract
Background: Neuroendocrine tumor is a rare neoplasm, then, it was difficult to examine using in vitro or animal models. Recently, patient-derived tumor organoid (PDTO) is considered as a promising method to analyze natural characteristics of human tumor, because PDTO is cultured in near-natural circumstances compared with cell lines. We established PDTO of neuroendocrine tumor (NET) utilizing operative samples from a pancreatic NET patient. Aim: Aim of this study is to establish organoid derived from an operative sample of pancreatic NET patient and to compare its characteristics with original tumor using immuno-histochemistry. Material and Method: A pancreatic NET tissue derived from operative sample was cut into small pieces and was treated by collagenase. Prepared tissues were 3-dimensionally cultured on the Matrigel in a serum-free medium (Advanced MEM/F12) with 4 growth factors (Respondin, EGF, Rock inhibitor, Noggin), then PDTO was established. To evaluate growth rate of PDTO, Major axis of the organoid was measured on the day 1, 2, 3, and 6. One week after primary culture of the organoid, subculture was performed. Then major axis of the 2nd, 6th and 7th filial organoid was also measured and compared with each filial. To evaluate characteristics of PDTO as neuroendocrine tumor, immunohistochemistry was performed for the 1st, 2nd and 3rd filial PDTO using anti-chromogranin-A antibody (Dako, mouse IgG), anti-synaptophysin antibody (Abcam, rabbit IgG), anti-NCAM antibody (Abcam mouse IgG) and Neuro-specific enolase (Dako, rabbit IgG). Results: Growth rate of the 2nd and 3rd filial on the day 6 did not show significant difference compared with that of the 1st filial. On the other hand, Growth rate of the 2nd and 3rd filial was significantly lower than that of the 1st filial. Expression of the 4 factors in the 1st, 2nd and 3rd filial PDTO was kept as much as the primary tumor. Conclusion: PDTO derived from neuroendocrine tumor showed the same characteristics as the primary tumor. The 6th and 7th filial PDTO might show cellular aging.

Abstract
This study conducted mercury (Hg) isotopic analysis, which has been expected as a new indicator for understanding the behavior of atmospheric Hg. The dominant atmospheric Hg species, namely gaseous elemental mercury (GEM, Hg0), were collected at the Cape Hedo Atmosphere and Aerosol Monitoring Station (CHAAMS) in Okinawa, Japan, for evaluating possible source(s) and transformation process(es) of Hg. The Hg isotopic compositions of GEM samples showed that the mass-dependent fractionation (MDF) of δ202Hg and the mass-independent fractionation (MIF) of Δ199Hg ranged from -2.15‰ to 0.79‰ and from -0.32‰ to 0.00‰, respectively. The results were classified into two groups: (1) negative δ202Hg and near-zero Δ199Hg in summer and (2) near-zero δ202Hg and negative Δ199Hg in the other season. According to the NOAA Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model, the dominant air masses traveled from East Asia during winter and South and East Asia during summer. However, the air masses also traveled from mainland Japan and rotated around Okinawa before reaching CHAAMS. In contrast, clear positive correlations between δ202Hg values and CO and PM2.5 concentrations were observed during summer. A small peak of Ox concentration was observed at three atmospheric monitoring stations, namely Nago, Naha, and Miyako Island during summer. Since Miyako Island is located ∼370 km southwest of CHAAMS, the main emission source of GEM transported to CHAAMS was not from mainland Okinawa but traveled from the southwest during summer.

Abstract
Approximately 20-30% of cancers are associated with hypercalcemia, and this is a complication often encountered in cancer care. Hypercalcemia causes disorders such as disturbance of consciousness and, in severe cases, kidney failure and even death. In this report, we present a case of malignant ameloblastoma associated with uncontrollable hypercalcemia followed by a life-threatening disease course. In this case, hypercalcemia shortened the period of home care, and the medical staff could have extended this period by acquiring knowledge that leads to early detection and better control of hypercalcemia. In addition, the choice of the place for end-of-life care may have been expanded by considering the treatment of not only the malignant tumor but also hypercalcemia as its complication.

Abstract
Although many patients with terminal cancers desire to be cared for at home, frequently, such patients cannot be shifted to home care due to their unstable symptoms. In severe cases, emergency hospitalizations may be frequently required after introducinghome medical care. We report a case of makinghome medical care difficult due to repeated emergency hospitalizations despite of the patient's deep desire. Interviews were conducted with both the oncologist in charge of the case and a home physician, and their viewpoints were compared. For patients and their families to achieve desired livingconditions, it was considered necessary to give supportive medical care that meet their desires until the end of their lives as mutual viewpoints are taken in a good balance.

Abstract
Chemical coping also has an idea that it is an early stage of abuse and dependence of opioids, it is important to grasp the frequency, complaints, and risk factors of chemical coping. In this study, observational research was performed backwardly with 549 people using opioids who were newly requested to the palliative care team. Results revealed that 13 of 549 patients (2.4%)were diagnosed with chemical coping. In terms of a breakdown of the complaint, and it was following rate and reasons, 6 people(46%)felt easy, 2 people(15%)were anxious, 2 people(15%)could sleep, 2 people(15%)had unknown reasons, and 1(8%)was calm. Characteristics of each patient diagnosed with chemical coping included frequent psychiatric symptoms such as life expectancy of 3 months, opioid oral administration period of 1 year or more, disease incidence period of 1 year or more, anxiety, delirium, and depression. One benign disease also confirmed the transition to opioid dependence.

Abstract
UNLABELLED Root amputation, immunosuppressive therapy, mandibular tooth extraction, pre-existing inflammation, and longer duration of treatment with bone-modifying agents were significantly associated with an increased risk of medication-related osteonecrosis of the jaw. Hopeless teeth should be extracted without drug holiday before the development of inflammation in cancer patients receiving high-dose bone-modifying agents. INTRODUCTION No studies have comprehensively analyzed the influence of pre-existing inflammation, surgical procedure-related factors such as primary wound closure, demographic factors, and drug holiday on the incidence of medication-related osteonecrosis of the jaw (MRONJ). The purpose of this study was to retrospectively investigate the relationships between these various factors and the development of MRONJ after tooth extraction in cancer patients receiving high-dose bone-modifying agents (BMAs) such as bisphosphonates or denosumab. METHODS Risk factors for MRONJ after tooth extraction were evaluated with univariate and multivariate analyses. The following parameters were investigated in all patients: demographics, type and duration of BMA use, whether BMA use was discontinued before tooth extraction (drug holiday), the duration of such discontinuation, the presence of pre-existing inflammation, and whether additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. RESULTS We found that root amputation (OR = 22.62), immunosuppressive therapy (OR = 16.61), extraction of mandibular teeth (OR = 12.14), extraction of teeth with pre-existing inflammation, and longer duration (≥ 8 months) of high-dose BMA (OR = 7.85) were all significantly associated with MRONJ. CONCLUSIONS Tooth extraction should not necessarily be postponed in cancer patients receiving high-dose BMA. The effectiveness of a short-term drug holiday was not confirmed, as drug holidays had no significant impact on MRONJ incidence. Tooth extraction may be acceptable during high-dose BMA therapy until 8 months after initiation.

Abstract
Summary10 healthy female subjects and 15 female patients with essential hypertension were studied with respect to fibrinogen metabolism in a steady state. Autologous I-125-labeled fibrinogen (I-125-fibrinogen) was used as a tracer. Comparison of the results showed that plasma volume, t½ of plasma I-125-fibrinogen and fractional catabolic rate (j3p) of plasma fibrinogen were not appreciably different in both groups of subjects, but plasma fibrinogen concentration, and catabolic flux of (synthesis rate) were significantly higher in hypertensive subjects, whereas extravascular fibrinogen and fractional transcapillary transfer rate (j1) of were significantly decreased in the patients. Further analyses of the data in both groups showed that there were significant correlations between diastolic blood pressure (P) and j1 with a regression equation of j1 = e−0.0285P, between 1 and between and j1 with a regression equation of 1. These results indicate that the observed decrease of j1 triggered the transition from normal to pathological steady state and is responsible for the altered metabolism and distribution of fibrinogen in hypertensive subjects.

Abstract
SummaryStudies were made of the effects of heparin, typhoid vaccine and thrombophlebitis on factor X (F.X) metabolism in dogs, using 125-labelled F.X (125I-F.X) as a tracer. 10 healthy male dogs were used for control study and 5 male dogs were used for each of other studies. Plasma F.X concentration was measured by a solid-phase radioimmunoassay. In the control dogs, the plasma F.X concentration was 2.4 ± 0.2 (SD) mg per dl, the plasma F.X (x) was 1.2 ± 0.1(SD) mg per kg, the halflife of plasma 125I-F.X(t½) was 0.5 ± 0.01 (SD) days, the fractional catabolic rate (j3p) was 2.4 ± 0.1 (SD) per day and the catabolic flur (J3pX) (synthesis rate) was 2.9 ± 0.7 (SD) mg per kg per day. These results were not appreciably altered in heparinized dogs. However, a single intravenous injection of 2 ml typhoid vaccine caused a shortened t½ of 0.38 ± 0.01 (SD) days and a decrease of plasma F.X concentration to 1.3 ± 0.13 (SD) mg per dl. Studies in heparinized dogs showed similar effects of typhoid vaccine. Next, thrombophlebitis was produced by a previous method and its effects on F.X metabolism were studied. No detectable alterations of F.X metabolism were found. These results indicate that in health most F. X is directly catabolized without the formation of activated F.X (F.Xa), that the observed effects of typhoid vaccine are mostly due to an acceleration of the direct catabolism of F.X without F.Xa formation and finally that localized thrombophlebitis has no appreciable effects on F.X metabolism.

Abstract
SummaryProperties of human, canine, and porcine heparin and S-35-heparin were first studied. Their electrophoretic mobility through 10 g % polyacrylamide gels, specific activity and their filtration patterns through Sephadex G-200 columns were closely similar. Then, S-35-heparin (0.5 mg) and cold heparin (27 mg) were simultaneously injected intravenously into 5 dogs and their plasma behavior was compared. The plasma half-lives of S-35-heparin averaged 1.18 ± 0. 13 (SD) hr and was identical with that of cold heparin, but the half-lives were much shorter and averaged 0.46 ± 0.08 (SD) hr in 5 dogs when S-35-heparin alone was injected. Studies were next made of heparin affinity to proteins including canine antithrombin III (AT) by the use of Sephadex G-200 chromatography, polyacrylamide gel electrophoresis, and S-35-heparin as a tracer. It was found that S-35-heparin-binding to alpha1, beta, and gammaglobulins and fibrinogen was readily separable upon addition of 5 mg cold heparin, but that the binding to AT was inseparable by addition of cold heparin or by electrophoresis. However, in canine plasma, both S-35-heparin and cold heparin were mostly bound to proteins other than AT, suggesting that this might be the case in vivo. To further substantiate this, studies were made of the comparative behavior of I-125-labeled AT (I-125-AT) and S-35-heparin in dogs with the idea that the plasma half-lives of both should be equal if they were irreversibly bound to each other. The plasma half-lives of I-125-AT averaged 2.10 ± 0.05 (SD) days in 5 male dogs and 1.99 ± 0.04 (SD) days in 5 female dogs, and were much different from the half-life values of S-35-heparin as given above. These results indicate that heparin in vitro is more tightly bound to AT than to other proteins, that heparin in vivo is not irreversibly bound to AT and suggest that it is mostly bound to proteins other than AT in vivo.

Abstract
SummaryEffects of estradiol, progesterone, Cortisol, thrombophlebitis and typhoid vaccine on the synthesis and catabolism of antithrombin III (AT) in dogs were studied, using I-125-labeled AT (I-125-AT) as a tracer. Five dogs were used for each study. A single intramuscular injection of 20 mg estradiol caused a 20% decrease of plasma AT concentration in 6 days without appreciable changes in the plasma half-lives of I-125-AT but with a significant decrease in the fractional catabolic rate of I-125-AT (j3u). A single intramuscular injection of 250 mg progesterone did not produce any appreciable changes of plasma AT concentration, the plasma half-lives of I-125-AT or j3u. On the other hand, intravenous and intramuscular injections of a total of 750 mg Cortisol caused a 17 % increase of plasma AT concentration in a day after the injections without alterations of the plasma half-lives of I-125-AT or j3u. Next, thrombophlebitis was produced in dogs by a single intravenous injection of 1 ml 90% phenol into a leg vein occluded for 1 min by a gauze tourniquet and the effects of thrombophlebitis were studied. The results indicated that it did not cause appreciable changes of plasma AT concentration, the plasma half-lives of I-125-AT or j3u. However, studies of the effects of a single intravenous injection of 3 ml typhoid vaccine showed a 25 % decrease of plasma AT concentration in a day after the injection with a moderate acceleration of the decline rate of plasma I-125-AT and a 14% increase in j3u values. Further studies in heparinized dogs showed similar effects with typhoid vaccine. These results indicate that estradiol causes a decreased rate of AT synthesis, that progesterone has no appreciable effects on AT metabolism, that Cortisol increases the rate of AT synthesis, that localized thrombophlebitis has no appreciable effects on AT metabolism and that typhoid vaccine causes an increased j3u by unknown mechanisms which is not an accelerated coagulation process.

Abstract
SummaryProperties of purified and delipidated human tissue thromboplastins (TTPs) from brain (BTTP), lung (LTTP), arteries (ATTP) and placenta (PTTP) were studied. The extinction coefficients were closely similar with a mean value of 8.3 ± 0.01 (SD). The molecular weights were 200,000 ± 3,000 (SD) (BTTP), 90,000 ± 2,000 (SD) (LTTP), 110,000 ± 3,000 (SD) (ATTP) and 250,000 ± 4,000 (SD) (PTTP). The maximum activity of each delipidated TTP after relipidation was obtained when phospholipid-delipidated TTP ratio was 2.0, and the maximum specific activity was 440 units per mg BTTP, 270 units per mg LTTP, 80 units per mg ATTP and 600 units per mg PTTP. Ouchterlony analysis with anti-delipidated PTTP antibody showed the reaction of partial identity between delipidated TTPs and the antibody. Studies of the reactivity of I-125-delipidated TTPs with the antibody gave the following average values for % bound I-125-TTPs in 2 hours: 3.6± 0.2 (SD) % (I-125-BTTP), 11.0± 0.3 (SD) % (I-125-LTTP), 4.4±0.2 (SD) % (I-125-ATTP) and 13.7±0.3 (SD) % (I-125-PTTP). It was also found that the antibody markedly neutralized the coagulant activity of saline extracts of brain, lung and placenta. These results indicate that delipidated BTTP, LTTP, ATTP and PTTP are different while being similar in some aspects and that complete TTPs are not coated with lipids in a manner inaccessible to anti-delipidated PTTP antibody.

Abstract
SummaryA method was described for preparation of purified human prothrombin using repeated barium citrate adsorption and citrate elution, (NH4)2S04 fractionation, Sephadex chromatography and isoelectric precipitation. The produced prothrombins were then physicochemically analyzed. The extinction coefficient was 12.7 ± 0.82 (SD) and the specific activity, 2,563 ± 420 (SD) Iowa units per mg prothrombin. The amino acid composition in g% was as follows: aspartic acid, 8.64; threonine, 5.87; serine, 4.16; glutamic acid, 11.15; proline, 3.91; glycine, 3.96; alanine, 4.65; half cystine, 4.68; valine, 4.46; methionine, 1.14; isoleucine, 2.93; leucine, 6.18; tyrosine, 4.52; phenylalanin, 4.19; lysine, 4.78; histidine, 1.73; ammonia, 1.85; arginine, 6.91. The tryptophan and carbohydrate contents were not determined. The prothrombins were then labeled with 125I in a ratio of about 0.25 atom iodine per molecule of prothrombin and were used for studies of the metabolism and distribution of prothrombin in thirteen healthy men. A model was proposed for the human prothrombin system based on the assumptions that prothrombin is catabolized intravascularly without the formation of thrombin, and was tested against the observed behavior of injected 125I- prothrombin. The model closely predicted the observed behavior of 125I-prothrombin. The analytical results of the tracer data in thirteen healthy men by the methods derived from the model were as follows: The plasma prothrombin, 6.65 ± 1.10 (SD) mg per kg; the interstitial prothrombin, 6.0 ^ 1.9 (SD) mg per kg; the half-life of plasma 125I-prothrombin, 2.29 ± 0.14 (SD) days ; the transcapillary transfer rate of prothrombin, 10.2 ± 3.9 (SD) mg per kg per day; and the catabolic (synthetic) rate of prothrombin, 4.3 J: 1.0 (SD) mg per kg per day. These results support the concept that in healthy men prothrombin is degraded in plasma or spaces in rapid exchange with it generation of appreciable amounts of thrombin.

Abstract
Arthrocentesis has an effect of washing out inflammatory products that accumulate in the joint compartment of a dysfunctional temporomandibular joint (TMJ). The procedure removes inflammatory cytokines, which are pain-causing substances, for early reduction of TMJ pain and quick recovery of jaw function, thus increasing the possibility of a successful rehabilitation. The aim of this study was to investigate the relationship between arthroscopy synovitis grade in patients with unilateral high condylar fractures and concentrations of the pro-inflammatory cytokines tumour necrosis factor (TNF)-alpha as well as of matrix metalloproteinases (MMPs) in washed-out synovial fluid (SF) samples obtained from those patients. A total of 26 patients with unilateral high condylar fractures who underwent arthrocentesis for a therapeutic purpose were examined. SF samples were collected before performing arthroscopy to determine synovitis grade. The detection rates and concentrations of TNF-alpha and MMPs were determined, and their association with synovitis grade was analysed. TNF-alpha was detected in 23 and MMP-3 in 22 of the TMJs. There was a correlation between synovitis grade and concentration of TNF-alpha in the fracture group. Furthermore, the concentrations of TNF-alpha and MMP-3 were significantly higher as compared to the control group, comprised of TMJs on the non-fracture side of the same patients, while a correlation was also noted between TNF-alpha concentration and synovitis grade in the fracture group. The present findings may provide a biological/biochemical rationale for arthrocentesis as a reasonable treatment modality for high condylar fractures.
