Abstract
AIMS While past research suggested that living arrangements are associated with suicide death, no study has examined the impact of sustained living arrangements and the change in living arrangements. Also, previous survival analysis studies only reported a single hazard ratio (HR), whereas the actual HR may change over time. We aimed to address these limitations using causal inference approaches. METHODS Multi-point data from a general Japanese population sample were used. Participants reported their living arrangements twice within a 5-year time interval. After that, suicide death, non-suicide death and all-cause mortality were evaluated over 14 years. We used inverse probability weighted pooled logistic regression and cumulative incidence curve, evaluating the association of time-varying living arrangements with suicide death. We also studied non-suicide death and all-cause mortality to contextualize the association. Missing data for covariates were handled using random forest imputation. RESULTS A total of 86,749 participants were analysed, with a mean age (standard deviation) of 51.7 (7.90) at baseline. Of these, 306 died by suicide during the 14-year follow-up. Persistently living alone was associated with an increased risk of suicide death (risk difference [RD]: 1.1%, 95% confidence interval [CI]: 0.3-2.5%; risk ratio [RR]: 4.00, 95% CI: 1.83-7.41), non-suicide death (RD: 7.8%, 95% CI: 5.2-10.5%; RR: 1.56, 95% CI: 1.38-1.74) and all-cause mortality (RD: 8.7%, 95% CI: 6.2-11.3%; RR: 1.60, 95% CI: 1.42-1.79) at the end of the follow-up. The cumulative incidence curve showed that these associations were consistent throughout the follow-up. Across all types of mortality, the increased risk was smaller for those who started to live with someone and those who transitioned to living alone. The results remained robust in sensitivity analyses. CONCLUSIONS Individuals who persistently live alone have an increased risk of suicide death as well as non-suicide death and all-cause mortality, whereas this impact is weaker for those who change their living arrangements.

Ethical and societal aspects of radiological protection for offspring and next generations. Int J Radiat Biol 2023:1-11. [PMID: 37947483 DOI: 10.1080/09553002.2023.2281523] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Accepted: 10/31/2023] [Indexed: 11/12/2023]
Abstract
PURPOSE Over the last decade or so, ethical and societal aspects of radiological protection have received increasing attention. This is also reflected in the publications of the International Commission on Radiological Protection (ICRP). The current paper aims at identifying relevant ethical and societal topics which should receive attention in the context of radiological protection for offspring and next generations. MATERIALS AND METHODS We present a non-comprehensive review of the subject, based on presentation made at an ICRP workshop in Budapest in 2022. We first discuss the ethical values promoted by ICRP, and the application of these values in cases of (potential) pre-conceptual and prenatal radiation exposures. We then consider experience gained after the Fukushima accident indicating particular societal concerns about the health effects of such exposures. RESULTS AND CONCLUSIONS Beneficence/non-maleficence, prudence, justice and dignity, the "core values" of the system of radiological protection have special roles to play when heritable and/or in utero effects are to be considered. Prudence, in particular, must be taken account of in view of the fact that solid scientific data in humans are largely lacking in this area, and it is necessary to rely on insights from animal experiments as well as theoretical considerations. As regards societal considerations, the perception of risk among (potentially) affected populations needs to be taken seriously. Accountability, transparency, and inclusivity, the "procedural values" promoted by ICRP for the practical implementation of the system of radiological protection play a central role in overcoming skepticism and creating trust. Stakeholder involvement should emphasize cooperation and dialogue, which allows for the joint evaluation of an exposure situation by experts and affected people.

Search for the Majorana Nature of Neutrinos in the Inverted Mass Ordering Region with KamLAND-Zen. PHYSICAL REVIEW LETTERS 2023; 130:051801.

Abstract
The KamLAND-Zen experiment has provided stringent constraints on the neutrinoless double-beta (0νββ) decay half-life in ^{136}Xe using a xenon-loaded liquid scintillator. We report an improved search using an upgraded detector with almost double the amount of xenon and an ultralow radioactivity container, corresponding to an exposure of 970 kg yr of ^{136}Xe. These new data provide valuable insight into backgrounds, especially from cosmic muon spallation of xenon, and have required the use of novel background rejection techniques. We obtain a lower limit for the 0νββ decay half-life of T_{1/2}^{0ν}>2.3×10^{26} yr at 90% C.L., corresponding to upper limits on the effective Majorana neutrino mass of 36-156 meV using commonly adopted nuclear matrix element calculations.

Comparison of the effects of two commercially available prescription diet regimens on the fecal microbiomes of client-owned healthy pet dogs. Pol J Vet Sci 2022; 25:93-101.

Abstract
In the present study, we used next-generation sequencing to investigate the impacts of two commercially available prescription diet regimens on the fecal microbiomes of eleven client-owned healthy pet dogs. We tested an anallergenic diet on 6 dogs and a low-fat diet on 5 dogs. Before starting the study, each dog was fed a different commercial diet over 5 weeks. After collecting pre-diet fecal samples, the anallergenic or low-fat diet was administered for 5 weeks. We then collected fecal samples and compared the pre- and post-diet fecal microbiomes. In the dogs on the anallergenic diet, we found significantly decreased proportions of Bacteroides, Ruminococcaceae, and Fusobacteriaceae, belonging to the phyla Bacteroidetes, Firmicutes, and Fusobacteria, respectively. The proportion of the genus Streptococcus belonging to the phylum Firmicutes was significantly increased upon administering the anallergenic diet. In the dogs on the low-fat diet, although the phyla Actinobacteria and Bacteroidetes tended to increase (p=0.116) and decrease (p=0.147) relative to the pre-diet levels, respectively, there were no significant differences in the proportions of any phylum between the pre- and post-diet fecal microbiomes. The anallergenic diet induced a significantly lower diversity index value than that found in the pre-diet period. Principal coordinate analysis based on unweighted UniFrac distance matrices revealed separation between the pre- and post-diet microbiomes in the dogs on the anallergenic diet. These results suggest that, even in pet dogs kept indoors in different living environments, unification of the diet induces apparent changes in the fecal microbiome.

Abstract
Tongue muscle damage impairs speaking and eating, thereby degrading overall health and quality of life. Skeletal muscles of the body are diverse in embryonic origin, anatomic location, and gene expression profiles. Responses to disease, atrophy, aging, or drugs vary among different muscles. Currently, most muscle studies are focused on limb muscles and the tongue is neglected. The regenerative ability of tongue muscle remains unknown, and thus there is need for tongue muscle research models. Here, we present a comprehensive characterization of the spatiotemporal dynamics in a mouse model of tongue muscle regeneration and establish a method for the isolation of primary tongue-derived satellite cells. We compare and contrast our observations with the tibialis anterior (TA) limb muscle. Acute injury was induced by intramuscular injection of cardiotoxin, a cytolytic agent, and examined at multiple timepoints. Initially, necrotic myofibers with fragmented sarcoplasm became infiltrated with inflammatory cells. Concomitantly, satellite cells expanded rapidly. Seven days postinjury, regenerated myofibers with centralized nuclei appeared. Full regeneration, as well as an absence of fibrosis, was evident 21 d postinjury. Primary tongue-derived satellite cells were isolated by enzymatic separation of tongue epithelium from mesenchyme followed by magnetic-activated cell sorting. We observed that tongue displays an efficient regenerative response similar to TA but with slightly faster kinetics. In vitro, tongue-derived satellite cells differentiated robustly into mature myotubes with spontaneous contractile behavior and myogenic marker expression. Comparison of gene expression signatures between tongue and TA-derived satellite cells revealed differences in the expression of positional-identity genes, including the HOX family. In conclusion, we have established a model for tongue regeneration useful for investigations of orofacial muscle biology. Furthermore, we showed that tongue is a viable source of satellite cells with unique properties and inherited positional memory.

Colchicine protects against cartilage degeneration by inhibiting MMP13 expression via PLC-γ1 phosphorylation. Osteoarthritis Cartilage 2021; 29:1564-1574. [PMID: 34425229 PMCID: PMC8542595 DOI: 10.1016/j.joca.2021.08.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 07/17/2021] [Accepted: 08/10/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE Low molecular weight compounds that reduce the expression of MMP13 at the mRNA level might serve as disease-modifying osteoarthritis (OA) drugs (DMOADs). The objective of this study was to identify a candidate DMOAD that targets MMP13 expression. DESIGN High-throughput screening was performed to identify compounds that suppress inflammatory cytokine-induced MMP13 expression. Ingenuity pathway analysis (IPA) using isobaric tags for relative and absolute quantification (iTRAQ)-based proteomic analysis was conducted to identify signaling pathways related to cytokines. MMP13 expression in chondrocytes was evaluated through RT-qPCR and western blotting analyses. Additionally, 10-week-old mice were subjected to destabilization of the medial meniscus (DMM) surgery to induce OA and were sacrificed 12 weeks post-surgery for pathological examination. OA was evaluated using the OARSI scoring system. RESULTS Colchicine was identified as a DMOAD candidate as it inhibited inflammatory cytokine-induced MMP13 expression in vitro, and the colchicine-administered mice with DMM presented significantly lower OARSI scores (adjusted P: 0.0242, mean difference: 1.6, 95% confidence interval (CI) of difference: 0.1651-3.035) and significantly lower synovial membrane inflammation scores (adjusted P: 0.0243, mean difference: 0.6, 95% CI of difference: 0.06158-1.138) than mice with DMM. IPA further revealed that components of the Rho signaling pathways are regulated by cytokines and colchicine. IL-1β and TNF-α activate RAC1 and SRC signals, respectively, leading to the phosphorylation of PLC-γ1 and synergistic induction of MMP13 expression. Most notably, colchicine abrogates inflammatory cytokine-induced phosphorylation of PLC-γ1, leading to the induction of MMP13 expression. CONCLUSIONS Colchicine is a potential DMOAD candidate that inhibits MMP13 expression and consequent cartilage degradation by disrupting the SRC/RAC1-phospho-PLCγ1-Ca2+ signaling pathway.

Abstract
This study investigated changes in serum levels of hepatic, bone, and intestinal alkaline phosphatase (ALP) isoenzymes (ALP2, ALP3, and ALP5, respectively) in Holstein cows around parturition. Tartrate-resistant acid phosphatase 5b (TRAP5b) activity and calcium (Ca) concen-trations were also measured. We analyzed blood samples from 11 late-pregnant heifers (primipa-rous group) and 13 multiparous (2-4 lactations; multiparous group) cows at 3 weeks (18-24 days prepartum; -3 weeks), 2 weeks (17-11 days prepartum; -2 weeks), and 1 week (10-4 days prepar-tum; -1 weeks) before parturition; the day of calving (within 12 h post-calving; day 0); and 5 days postpartum (5 days). ALP3 activity was significantly higher in the primiparous group than in the multiparous group, whereas the activities decreased significantly in both groups after 5 days. ALP2 and ALP5 activities did not change, whereas ALP2 activity was significantly higher in the primiparous group than in the multiparous group. TRAP5b activity was significantly higher in the primiparous group than in the multiparous group and showed a transient significant increase at day 0. Ca concentration significantly decreased at day 0 in both groups; the Ca level at day 0 was significantly higher in the primiparous group than in the multiparous group. These data show that ALP3 activity in serum may indicate a change in osteoblastic bone forma-tion after calving, but further study is needed to determine the clinical application for measuring ALP isoenzymes in bovine medicine.

Abstract
Following the accident at Fukushima Daiichi nuclear power plant in 2011, a series of health literacy training workshops for local health workers was developed and implemented. This study aimed to analyse who among the intended audience gained the greatest benefit from the training. Nine health workers attended a workshop consisting of classroom training and a follow-up feedback assessment of materials they created in the workshop. The materials were assessed by a total of 131 intended readers. Using Sakai's tool, those items asking readers to rate the accessibility of written information were used to compare the materials before and after revision. The total score for Sakai's measure showed a significant improvement, and the elderly and those without regular doctor visits were more likely to notice improvements after revision. Such health literacy training could serve as a model programme to prevent inequity in access to health information in the face of a regional health crisis.

Abstract
To promote radiation protection and health promotion among returning residents (returnees) in coastal areas of Fukushima, eHealth principles were used to develop a new application tool (app) that can record radiation exposure and health status while providing comprehensive support to returnees. Intended users are returnees and health and welfare workers. After assessing their needs, a flowchart and prototype for operational logic were created using commercially available software tools. Professional developers will focus on improving the user interface and ensuring data security. The finished app will be compatible with mobile telephones and tablets. Utility and ease of use are paramount to serve returnees of all ages effectively.

Agarose gel electrophoresis pattern of serum alkaline phosphatase isoenzymes in Holstein cows during lactation. Pol J Vet Sci 2021; 23:317-319.

Abstract
A recent study found that an agarose gel electrophoresis (AGE) method yielded two distinct major bands corresponding to the hepatic and bone ALP isoenzymes (ALP2 and ALP3, respec-tively) in bovine serum treated with protease and neuraminidase (PN-treatment), although there were concerns that the intestinal ALP isoenzyme (ALP5) often overlapped with ALP3 in human serum treated with neuraminidase. Because ALP5 was separated from ALP3 in bovine serum treated with protease alone (P-treatment), we used a modified method employing both P- and PN-treated bovine sera to measure the activities of the three ALP isoenzymes in 53 lacta-ting Holstein cows: 24 primiparous and 29 multiparous. Upon electrophoresis, 51 of 53 samples (96.2%) subjected to P-treatment yielded a distinct fraction corresponding to ALP5, as did the control serum. All PN-treated sera yielded a definite ALP2 fraction. The ALP3 fraction was calculated as the remainder after excluding ALP2 and ALP5. The activities of total ALP (t-ALP) and ALP3 in primiparous cows were higher than those in multiparous cows (p ⟨ 0.001) at early-to-peak [10-110 days in milk (DIM)] and mid (111-220 DIM) lactation. In the multi-parous cows, the ALP3 activity at late lactation (221-477 DIM) was significantly higher than that at early-to-peak lactation. Thus, the modified AGE method described here is able to discrimi-nate three fractions of ALP isoenzymes in the sera of lactating cows. The AGE pattern of circu-lating ALP isoenzymes will contribute to the understanding of the physiological bone metabolism status in lactating cows.

Change in sense of food safety associated with social connectedness and information sources-A 10-year longitudinal survey before and after the Fukushima nuclear power plant accident. Public Health 2021; 194:156-162.

Abstract
OBJECTIVES This study analyzes the change in the sense of food safety over time, from 2 years before to 8 years after the Fukushima accident in 2011, and its association with social connectedness using cohort data, taking into account regional differences in Fukushima Prefecture. STUDY DESIGN Repeated cross-sectional data from Fukushima Prefectural Government from 2009 to 2018 were used. METHODS We randomly selected 1300 people every fiscal year (FY). The survey gathered data on age, gender, occupation, residential region, and the explanatory variables 'sense of social connectedness' and 'recovery-related information source' (information source). The prefecture was divided into three regions for the survey-Hamadori region, where the nuclear power plant is located, Nakadori region, where the air dose rate after the earthquake was high, and in Aizu, far from the nuclear power station but has suffered from harmful rumors. RESULTS Focusing on FY 2014, when the sense of safety first showed recovery, we performed a binominal logistic regression analysis with 'sense of safety' as the outcome and 'sense of social connectedness' and 'information source' as the explanatory variables. The sense of safety significantly decreased in all regions in 2011 relative to earlier years. The sense of food safety decreased markedly in Hamadori and Nakadori but started to improve 3 years after the earthquake and reached the pre-earthquake level in 2018. The effect sizes were larger in the Hamadori region and in Nakadori than in Aizu. In FY 2014, multivariate analysis found that a sense of food safety was significantly positively associated with a sense of social connectedness, whereas the use of information from newspapers and TV and word of mouth was negatively associated. CONCLUSION Although the recovery of a sense of food safety may take some time, a focus on social connectedness during recovery and scrutiny of information sources may facilitate recovery. Health communication has an important role when the provider sends information intelligibly and the recipient can distinguish good news from bad and link it to self-determination. It is necessary to improve literacy.

Abstract
Objective Neuroendocrine neoplasms (NENs) are rare and indolent diseases, but the efficacy of treatment without surgical resection is temporary and limited. Targeted immunotherapy is an important treatment strategy in several cancers. However, the tumor and host immune reactions in the NEN microenvironment are poorly understood. Therefore, we investigated the immune checkpoint system and host immune response in pathological NEN specimens. Methods The expression of the mismatch repair proteins MSH2, MSH6, PMS2, and MLH1 was immunohistochemically detected in archival tissue samples obtained from 20 patients with gastroenteropancreatic NENs. We additionally assessed the expression of programmed death (PD)-1, PD-L1, and the tumor-infiltrating lymphocyte (TIL) markers CD8 and family of transcription factor P3 (FOXP3). Results All 20 NENs expressed the mismatch repair proteins MSH2, MSH6, PMS2, and MLH1. The PD-L1 and/or PD-1 expression in the tumor cells and/or TILs was confirmed in 75% of the cases. PD-1-, CD8-, and FOXP3-positive TILs were more frequently associated with PD-L1-positive tumors than with PD-L1 negative tumors (PD-1: 19.5 vs. 7.3, CD8: 18.1 vs. 7.1, FOXP3: 13.2 vs. 3.2, p=0.438, p=0.419, P=0.603, respectively). The number of cells positive for PD-1 tended to gradually increase in increasing grade of NENs but did not reach significance (Grade 1: 5.8, Grade 2: 10.2, NEC: 18.1, p=0.903). Conclusion NENs consistently express mismatch repair proteins but have a high expression of PD-L1 and/or PD-1 in the tumor microenvironment. NEC and PD-L1-positive NENs may be immunologically "hot" tumors, so an immunological approach may be an appropriate treatment strategy for these tumors.

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
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.

Sarcopenia is a reliable prognostic factor in patients with advanced pancreatic cancer receiving FOLFIRINOX chemotherapy. Pancreatology 2019; 19:127-135. [PMID: 30473464 DOI: 10.1016/j.pan.2018.11.001] [Citation(s) in RCA: 60] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2018] [Revised: 11/05/2018] [Accepted: 11/08/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND/OBJECTIVES FOLFIRINOX is the reliable treatments for pancreatic cancer, but it has a relatively high toxicity and the selection of suitable patients for this regimen remains challenge. On the other hand, sarcopenia is one of the important prognostic factors of pancreatic cancer. The aim of this study was to investigate the effect of sarcopenia on overall survival (OS) and time to treatment failure (TTF) in patients with pancreatic cancer who received FOLFIRINOX. METHODS Clinical data of consecutive patients treated with FOLFIRINOX at our institution from 2011 to 2017 was retrospectively reviewed. Skeletal muscle index (SMI) and adipose tissue index (ATI) at the third lumbar spine level was calculated from computed tomography (CT) images. The association between clinical factors (SMI and ATI), and OS and TTF were determined using univariate and multivariate analyses. RESULTS We assessed 82 patients. The median OS of sarcopenia and the non-sarcopenia patients were 11.3 and 17.0 months, respectively (hazard ratio [HR], 2.49; 95% confidence interval [CI], 1.43-4.32; p = 0.001). Median TTF was 3.0 and 6.1 months in the sarcopenia and the non-sarcopenia patients, respectively (HR, 1.67; 95% CI, 1.03-2.71; p = 0.032). Multivariate analyses revealed that sarcopenia (HR, 1.37; 95% CI, 1.01-1.87; p = 0.045) was an independent prognostic factor of OS. High ATI (p = 0.022) and sarcopenic obesity (p = 0.008) were significantly associated with hematologic toxicity. CONCLUSIONS Sarcopenia is an independent indicator of poor prognosis in patients with pancreatic cancer who received FOLFIRINOX, while ATI and sarcopenic obesity predicted severe hematologic toxicity.

Abstract
Introduction: Neuroendocrine tumor (NET) is a rare cancer, however, morbidity rate is increasing every year. Recently, effective molecular targeting drugs for NET were developed and leading acceptable results, however, it is still not enough. Immune checkpoint inhibitor is becoming a very effective drug in malignant melanoma, lung cancer, and some kind of cancer showing microsatellite instability (MSI).
Aim: Aim of this study is to investigate NET about MSI status and immune status of microenvironment using NET patients' operative or biopsy samples.
Method: Patients were 20 NETs, male: 11, female: 9, G1: 6, G2: 8, G3: 6, pancreas: 11, duodenum: 4, colon: 2, liver: 1, unknown: 2. Using patients' samples by operative resection or biopsy, examinations by immunohistochemistry were performed to confirm MSI status using MSH2, MSH6, PMS2 and MLH1 antibody and count the cell number expressing PD-L1, PD-1, CD8 or Foxp3. Expression of MSH2, MSH6, PMS2, MLH1 and PD-L1 was evaluated on tumor cells. Specimens were categorized as IHC negative or positive if < 1% or > 1% of cells were stained by each monoclonal antibody. Expression of PD-1, CD8, Foxp3 was evaluated on the infiltrating lymphocyte of intratumor and peritumor respectively. Positive cells absolute number of each staining were counted in the 3 hot spot field (X400) and then the average of the 3 field of each specimen was utilized.
Results: MSI: Expression of the 4 mismatch repair protein could be detected in the all 20 NETs tumor, then there was no case showing MSI. PD-L1 was detected in the 15 cases (75%). PD-L1 was expressed in the surface of tumors. PD-1 was also detected 15 cases (75%). PD-1 was expressed in the surface of infiltrative intratumoral and peritumoral lymphocyte. Both of PD-L1 in the tumor and PD-1 in the lymphocyte were detected in the 12 cases (60%). PD-L1 was detected in 72.7% of pancreatic NET, 72% of gastroenteral NET. PD-L1 was detected in 100% of NET-G1, 75% of G2 and 50% of G3. The absolute number of intratumoral PD-1+ lymphocyte, CD8+ lymphocyte or Foxp3+ lymphocyte was higher in the PD-L1+ tumor than in the PD-L1- tumor. In peritumor, there was not a similar tendency. In the PD-L1 positive NET, the absolute number of intratumoral PD-1+ lymphocyte or CD8+ lymphocyte increased according to NET grade.
Conclusion: Seventy-five% of GEP-NET expressed PD-L1. It might be higher rate of PD-L1 expression compared with other cancers. The absolute number of Intratumoral infiltrating lymphocyte expressing PD-1 or CD8 was also high. There might be a fraction of a good target for immune check point therapy in NETs.

Abstract
BACKGROUND/AIMS Somatostatin receptor (SSTR) scintigraphy (SRS) is the standard imaging modality for evaluation of gastroenteropancreatic neuroendocrine tumor (GEP-NET) in Western countries. However, this modality was not approved in Japan until recently. The purpose of this study was to evaluate the clinical efficacy of SRS for detecting GEP-NET in Japanese patients. METHODS Japanese patients with advanced GEP-NET were enrolled and evaluated by the SRS and CT. We also compared SRS and immunohistochemical expression of SSTR type 2a (SSTR2a). RESULTS We enrolled 16 patients and the primary sites were the pancreas in 9, the stomach in 1, the small intestine in 2, the colon in 3, and unknown in 1. SRS showed positive findings in 3 (100%) of grade 1 (G1) and in 12 (92.3%) of grade 2 (G2) lesions. In the liver, SRS and CT detected lesions in 13 and 14 cases, respectively. The concordance rate of SSTR2a expression with SRS findings was 93.8% in the whole body and 92.9% in the liver. CONCLUSIONS SRS could detect almost all of G1 and G2. SRS could be useful to detect lesions, with a high concordance rate with CT and pathological findings. We confirmed that SRS is a useful and reliable modality for Japanese patients.

Abstract
AIMS To assess the predictive ability of a genetic risk score for the incidence of Type 2 diabetes in a general Japanese population. METHODS This prospective case-control study, nested within a Japan Public Health Centre-based prospective study, included 466 participants with incident Type 2 diabetes over a 5-year period (cases) and 1361 control participants, as well as 1463 participants with existing diabetes and 1463 control participants. Eleven susceptibility single nucleotide polymorphisms, identified through genome-wide association studies and replicated in Japanese populations, were analysed. RESULTS Most single nucleotide polymorphism loci showed directionally consistent associations with diabetes. From the combined samples, one single nucleotide polymorphism (rs2206734 at CDKAL1) reached a genome-wide significance level (odds ratio 1.28, 95% CI 1.18-1.40; P = 1.8 × 10-8 ). Three single nucleotide polymorphisms (rs2206734 in CDKAL1, rs2383208 in CDKN2A/B, and rs2237892 in KCNQ1) were nominally significantly associated with incident diabetes. Compared with the lowest quintile of the total number of risk alleles, the highest quintile had a higher odds of incident diabetes (odds ratio 2.34, 95% CI 1.59-3.46) after adjusting for conventional risk factors such as age, sex and BMI. The addition to the conventional risk factor-based model of a genetic risk score using the 11 single nucleotide polymorphisms significantly improved predictive performance; the c-statistic increased by 0.021, net reclassification improved by 6.2%, and integrated discrimination improved by 0.003. CONCLUSIONS Our prospective findings suggest that the addition of a genetic risk score may provide modest but significant incremental predictive performance beyond that of the conventional risk factor-based model without biochemical markers.

Abstract
Akathisia is a condition wherein sitting calmly and quietly is impossible, with a representative complaint of restless legs. It is generally assumed to be caused by anti-dopamine activity. In severe cases, it has been known to result in suicide attempt. We reported a case of drug-induced akathisia with difficulty in oral intake, in which fentanyl citrate sublingual tablets were found to be effective in relieving symptoms. The patient was a female aged 50's who had a gastric cancer with peritoneal dissemination causing pain and vomiting. Palliative care was requested for management of symptoms. Metoclopramide and haloperidol were administered for vomiting. However, because of the complaints of restless legs, the case was diagnosed as drug-induced akathisia. Fentanyl citrate sublingual tablets were then administered for pain management, resulting in temporary improvement of akathisia symptoms.

Abstract
We investigated the usefulness of suvorexant for complicated delirium in patients with cancer who experience sleep disturbance during hospitalization. Nine patients with malignant tumors complicated with symptoms of delirium and insomnia were included in this study; their palliative care was managed by the palliative care team of our hospital for a period of one year from April 2016 to March 2017. A retrospective follow-up study was then conducted. The Japanese version of DRS-R98 was used to evaluate the severity of the patient's delirium. The total severity score of DRS-R98 significantly decreased after the administration of suvorexant when compared to the score before its administration(6.66±1.73 vs 10±3.20, p=0.0031). In addition, suvorexant did not exhibit any harmful effects. Our results indicate that suvorexant was useful in alleviating delirium symptoms in cancer patients who experience sleep disturbance.

Abstract
Superselective intra-arterial chemoradiation therapy for oral cancer induces the complication of mucositis. Although the associated pain is controlled using opioids, major questions from patients in clinical practice are as follows:(1)the mean number of days from the completion of superselective intra-arterial chemoradiation therapy to the discontinuation of opioid administration, and(2)patient factors enabling the discontinuation of opioids. The purpose of this study was to clarify these points. A retrospective follow-up study was conducted from April 2016 to March 2017 on patients who underwent superselective intra-arterial chemoradiation therapy at our department of oral surgery. The patients were divided into 2 groups:one who discontinued opioids, and the other who did not. Clinical backgrounds and data were compared between the 2 groups. The mean number of days from the completion of superselective intra-arterial chemoradiation therapy to the discontinuation of opioid administration was 51±34.4 days. The absence of diabetes and deliria during treatment were determined as factors contributing to the discontinuation of opioids.

Abstract
Superselective intra-arterial chemoradiation therapy for locally advanced oral cancer induces complications such as mucositis, which impedes oral intake. Thus, at our hospital, a gastrostomy is performed in almost all patients during the treatment period to ensure the presence of an alternative administration route for nutrition and drugs. The purpose of this study was to calculate the mean number of days from completion of superselective intra-arterial chemoradiation therapy to the decannulation of gastrostomy, and extract patient factors for the decannulation. A retrospective follow-up study was conducted from April 2016 to March 2017 on patients who underwent superselective intra-arterial chemoradiation therapy at our department of oral surgery. The patients were divided into 2 groups:one who was decannulated and the other who did not. Clinical backgrounds and data were compared between the 2 groups. In the group with the decannulation, the mean period from treatment completion to the decannulation was 132±51.6 days. Heavy alcohol consumption, absence of haphalgesia before treatment, and possible securement of the opening with the breadth of 3 fingers, were determined as factors contributing to the decannulation of gastrostomy tube.

Abstract
A 52-year-old woman had been prescribed oral medication of acetaminophen, non-steroidal anti-inflammatory drugs (NSAIDs), and oxycodone for intractable pain associated with thoracic metastasis of breast cancer. However, the pain control was poor. Although pregabalin and gabapentin were used as supplementary analgesics, they could not be continued because of their side effects. Based on the noradrenalin reincorporation-inhibiting action of tapentadol, a combination therapy of tapentadol and oxycodone was introduced and satisfactory pain control was achieved. No side effects from the combined opioids were observed. This finding indicates the potential of administrating a combination therapy of m-opioid receptor agonists(such as morphine, oxycodone, and fentanyl)with tapentadol, which has a noradrenaline reincorporation-inhibiting action, as an effective remedy for alleviating intractable pain complicated with neuropathic pain.

Abstract
Summary
Objectives
: Our objective is to investigate diabetes- related alteration of glucose control in diurnal fluctuations in normal daily life by detrended fluctuation analysis (DFA).
Methods
: The fluctuations of glucose of 12 non-diabetic subjects and 15 diabetic patients were measured using a continuous glucose monitoring system (CGMS) over a period of one day. The glucose data was calculated by the DFA method, which is capable of revealing the presence of long-range correlations in time series with inherent non-stationarity.
Results
: Compared with the non-diabetic subjects, the mean glucose level and the standard deviation are significantly higher in the diabetic group.The DFA exponent α is calculated, and glucose time series are searched for the presence of negatively (0.5 < α <1.5) or positively (1.5 < α) correlated fluctuations. A crossover phenomenon, i.e. a change in the level of correlations, is observed in the non-diabetic subjects at about two hours; the net effects of glucose flux/reflux causing temporal changes in glucose concentration are negatively correlated in a “long-range" (> two hours) regime. However, for diabetic patients, the DFA exponent α = 1.65 ± 0.30, and in the same regime positively correlated fluctuations are observed, suggesting that the net effects of the flux and reflux persist for many hours.
Conclusions
: Such long-range positive correlation in glucose homeostasis may reflect pathogenic mechanisms of diabetes, i.e., the lack of the tight control in blood glucose regulation. Using modern time series analysis methods such as DFA, continuous evaluation of glucose dynamics could promote better diagnoses and prognoses of diabetes and a better understanding of the fundamental mechanism of glucose dysregulation in diabetes.

Abstract
BACKGROUND This study aimed to determine the maximum tolerated dose (MTD), dose-limiting toxicity, and efficacy of second-line chemotherapy with FOLFIRINOX after gemcitabine (GEM)-based chemotherapy failure in metastatic pancreatic cancer (MPC). METHODS We studied 18 histopathologically proven MPC patients. The schedule was 85 mg/m oxaliplatin, irinotecan, and 400 mg/m leucovorin, followed by 400 mg/m 5-fluorouracil (5-FU) as a bolus on day 1 and 2400 mg/m 5-FU as a 46-hour continuous infusion biweekly. The dose of irinotecan was defined as follows: level 0: 100 mg/m, level 1: 125 mg/m, level 2: 150 mg/m, and level 3: 180 mg/m. The doses of other drugs were fixed. The primary endpoint of phase II study was the response rate (RR). RESULTS We initially evaluated 6 patients in a phase I study. One patient developed neutropenia and 1 patient developed hyperglycemia and severe infection. Accordingly, level 1 was chosen as the MTD. According to a phase II study, the RR was 22.2% and the disease control rate was 61.1%. The progression-free survival and overall survival were 2.8 (range, 0.7-19.1) and 9.8 (2.4-19.8) months, respectively. The most common severe adverse event was neutropenia (66.7%). Febrile neutropenia occurred in 1 (5.6%) case. CONCLUSION The recommended dose was 85 mg/m oxaliplatin, 100 mg/m irinotecan, and 400 mg/m leucovorin, followed by 400 mg/m 5-FU as a bolus on day 1 and 2400 mg/m 5-FU as a 46-hour continuous infusion. These results indicate that second-line FOLFIRINOX is a marginally effective treatment for GEM-based chemotherapy failure cases.

Abstract
772 Background: The comparison of prognosis between right and left-sided colon cancer (RC, LC) has recently attracted a lot of attention. We examined whether primary location of colo-rectal cancer represents a prognostic factor of patients received curative resection of liver metastasis. Methods: We reviewed all patients undergoing resection of liver metastasis of colo-rectal cancer from1992 to 2013 in the 2 YCU hospitals, and selected eligible 377 patients (59 [15.6 %] with RC, 318 [84.4 %] with LC) undergoing R0 or 1 resection of primary and metastatic lesions. Patients with transverse colon cancer were excluded. We stratified patients according to previously-reported prognostic factors of hepatic metastasis resection, and conducted univariate analysis by Log Rank test to compared overall survival (OS) in each stratum. Using those results, independent factors affecting OS were determined by multivariable Cox regression. Results: The median OS of 377 patients was 66 months, and disease free survival (DFS) was 11.6 months. Univariate analysis revealed that the number and maximum diameter of liver metastasis, existence of other metastasis apart from liver, CEA, and having pre- or post- operative chemotherapy showed significant difference of OS. Primary site did not show significant difference of OS (p = 0.547), but median OS of LC (67 months) was 24 months longer than of RC. As for DFS, there was no significant difference between RC and LC (10.75 vs. 11.6 months, p = 0.873). Multivariate Cox regression analysis was conducted using former factors showing significant difference and primary site. Then primary site was an independent prognostic factor (p = 0.047). LC showed a lower risk than RC (HR: 0.675). Conclusions: The primary site did not affect DFS, but could become a prognostic factor of OS with patients undergoing curative resection of liver metastases. It suggested that curative resection of liver metastases could contribute to prolong survival, regardless of RC or LC. And there is some possibility that the primary site affects prognosis after post-operative recurrence of colo-rectal cancer liver metastases.

Abstract
This article examines postdisaster public health activities (focusing primarily on parenting support) through collaboration between universities and local government, and reports on the support provided to public health nurses, who are the gatekeepers of community health. For a year after the Fukushima disaster, discussions were held on the short- and long-term measures for responding to the concerns of parents, who face difficulty interpreting risks. Child health checkup data and mothers' counselling sessions with public health nurses were analysed to gather evidence to reinforce the health system over the long term. As the results of the analysis showed a need for the development of a system for communicating health information in ways that are accessible to residents, a health literacy training programme was developed and implemented for public health nurses in Fukushima Prefecture.

Abstract
The non-clinical pharmacokinetics (PK) of TAK-357, a highly lipophilic (clogP>6) potential agent for the amelioration of Alzheimer's disease, was investigated in rats and dogs. A long half-life (t1/2) in plasma was observed in animals and a low total body clearance with high distribution volume was consistent with the long t1/2. The absorption, distribution, metabolism and excretion (ADME) studies using radiolabeled TAK-357 revealed that the total radioactivity was highly distributed to the adipose tissues and sustained with high concentration for over 4 weeks after oral administration. The metabolite analysis also revealed that the main component in the plasma and adipose tissues was unchanged TAK-357. The major elimination route of absorbed TAK-357 was suggested to be by metabolism. An ADME study indicated that the adipose tissue is the main depot of remaining TAK-357 in the body and slow release from the adipose tissues contributes to the long t1/2. The PK of highly lipophilic compounds have a tendency to be affected by body weight changes especially changes in the adipose tissues. Therefore, it is considered that the relationship between the plasma levels of TAK-357 and the body weight should be evaluated carefully during the clinical trials.

AIMS To evaluate the effect of multifaceted interventions using the Achievable Benchmark of Care (ABC) method for improving the technical quality of diabetes care in primary care settings. METHODS We conducted a 1-year cluster randomized controlled trial in 22 regions divided into an intervention group (IG) or control group (CG). Physicians in the IG received a monthly report of their care quality, with the top 10% quality of diabetes care scores for all physicians being the achievable benchmark. The change in quality-of-care scores between the IG and CG during follow-up was analysed using a generalized linear model considering clustering. RESULTS A total of 2199 patients were included. Their mean (sd) age was 56.5 ± 5.9 years and the mean (sd) HbA1c level was 56.4 ± 13.3 mmol/mol (7.4 ± 1.2%). The quality-of-care score in the CG changed from 50.2%-point at baseline to 51%-point at 12 months, whereas the IG score changed from 49.9%-point to 69.6%-point, with statistically significant differences between the two groups during follow-up [the effect of intervention was 19.0%-point (95% confidence interval 16.7%- to 21.3%-point; P < 0.001)]. CONCLUSIONS Multifaceted intervention, measuring quality-of-care indicators and providing feedback regarding the quality of diabetes care to physicians with ABC, was effective for improving the technical quality of care in patients with Type 2 diabetes in primary care settings.

Abstract
A 49-year-old Japanese man had multiple huge masses (max. size 60 mm diameter) in his liver. These tumors were pathologically diagnosed by tumor biopsy as epithelioid hemangioendotheliomas of the liver. In this case, multiple liver tumors existed in both lobes. Also this patient did not agree to receive surgical resection including liver transplantation. Chemotherapy with sorafenib at a dose of 400 mg/body twice a day was started. About 6 months later, CT findings revealed that these tumors were shrinking slightly; 33 months later, the tumors obviously showed a partial response in accordance with the Response Evaluation Criteria in Solid Tumors (RECIST). Also 60 months later, the partial response continued with sorafenib monotherapy.

Abstract
297 Background: The purpose of this study was to determine the maximum tolerated dose (MTD), dose limiting toxicities (DLT), and efficacy of the second-line chemotherapy (after gemcitabine based chemotherapy) by FOLFIRINOX with unresectable pancreatic cancer. Methods: The subjects were histopathologically proven unresectable pancreatic cancer patients. The schedule was oxaliplatin 85mg/m2 on day1, irinotecan on day1, leucovorin 400mg/m2 on day 1 followed by FU 400mg/m2 as a bolus on day 1 and 2400mg/m2 as 46-hour continuous infusion biweekly. We were planned the dose of oxaliplatin, leucovorin and FU were fixed and the dose of irinotecan was defined as follows: level 0: 100mg/m2, level 1: 125mg/m2, level 2: 150mg/m2, and level 3: 180mg/m2. We started level 1 and at least three patients were enrolled at same dose two cycles. If DLT was observed two patients in six or three patients, we suspected the level was MTD. We also evaluated this study as phase II. Primary end point was response rate (RR). We also evaluated progression free survival (PFS), overall survival (OS) and adverse event (AE). Results: Eighteen patients were enrolled in this study (man: n = 11, woman: n = 7). We evaluated initial eight patients as phase I study. One patient had neutropenia and another one patient had hyperglycemia and severe infection. We decided level 1 was MTD and recommended dose was level 0. According to phase II study, RR was 22.2% (CR: n = 0, PR: n = 4, SD: n = 7, PD: n = 7) and disease control rate (DCR) was 61.1%. PFS was 2.8 (0.7-11.7) months and OS was 9.8 (2.4-14.4) months. The most common severe AE was neutropenia (66.7%). Fibril neutropenia was occurred one (5.6%) case. Conclusions: Recommended dose was oxaliplatin 85mg/m2 on day1, irinotecan 100mg/m2 on day1, leucovorin 400mg/m2 on day 1 followed by FU 400mg/m2 as a bolus on day 1 and 2400mg/m2 as 46-hour continuous infusion. RR was 22.2% and major AE was neutropenia but FN was rare. Second-line FOLFIRINOX is marginally effective treatment for gemcitabine-base chemotherapy failure cases.

Abstract
A prototype C(6+) injector using a laser ion source has been developed for a compact synchrotron dedicated to carbon ion radiotherapy. The injector consists of a laser ion source and a 4-vane radio-frequency quadrupole (RFQ) linac. Ion beams are extracted from plasma and directly injected into the RFQ. A solenoid guides the low-energy beams into the RFQ. The RFQ is designed to accelerate high-intensity pulsed beams. A structure of monolithic vanes and cavities is adopted to reduce its power consumption. In beam acceleration tests, a solenoidal magnetic field set between the laser ion source and the RFQ helped increase both the peak currents before and after the RFQ by a factor of 4.

Abstract
Orteronel is newly identified as a selective 17,20-lyase inhibitor for an agent for castration resistant prostate cancer. The absorption and disposition of [(14)C]orteronel were investigated in rats and monkeys. Orteronel was extensively excreted into rat and monkey urine in an unchanged form after oral administration. The unbound based renal clearances in rats and monkeys were greater than the respective glomerular filtration rates (GFR), suggesting that urinary tubular secretion plays an important role in the renal excretion of orteronel. Therefore, the uptake of [(14)C]orteronel was investigated using rat kidney slices to estimate the contribution of carrier-mediated transport on the urinary tubular secretion. The uptake study using rat kidney slices suggested that the transport of orteronel from the blood circulation to the kidney was mediated by a digoxin sensitive transport system represented by Oatp4c1 and non-saturable components. Furthermore, the saturable component accounted for a limited fraction of the total renal uptake by rat kidney slices. These results suggested that non-saturable uptake mainly contributed to the renal excretion of orteronel in rats.
