Abstract
PURPOSE Studies have shown that surgical site infection (SSI) incidence is lower in patients undergoing laparoscopic surgery. Therefore, we reported the SSI countermeasures adopted by our institution and aimed to evaluate the association between SSI occurrence and postoperative colorectal cancer recurrence and the usefulness of laparoscopic surgery for prognosis. METHODS Among the patients with colorectal cancer who underwent radical surgery at our hospital between January 2015 and December 2017, 197 with stage I-III cancer without distant metastases were included. We retrospectively analyzed patients' electronic medical records and classified them into the non-SSI (without SSI, n = 159) and SSI (with SSI, n = 38) groups. We calculated and compared the 5-year relapse-free survival (RFS) and overall survival (OS) rates. Additionally, we assessed the relationship between prognosis in the non-SSI, incisional SSI, and organ/space SSI groups and the usefulness of laparoscopic surgery. RESULTS The 5-year RFS and OS were 80.5% versus 63.2% (P = 0.024; hazard ratio [HR], 2.065; 95% confidence interval [CI], 1.099-3.883) and 88.7% versus 84.2% (P = 0.443; HR, 1.436; 95% CI, 0.570-3.617), respectively. The SSI group had a significantly worse 5-year RFS prognosis. Regarding the relationship with laparoscopic surgery, the SSI incidence was 45.0% (9/20 cases) and 16.4% (29/177 cases) with laparotomy and laparoscopic surgery, respectively, indicating a significantly reduced SSI occurrence with laparoscopic surgery (P = 0.005). CONCLUSION Patients with SSI were at high risk for colorectal cancer recurrence, and laparoscopic surgery may be useful for reducing SSI.

Abstract
The American Joint Committee on Cancer (AJCC) 8th edition T-staging system for distal cholangiocarcinoma (DCC) proposes classification according to the depth of invasion (DOI); nevertheless, DOI measurement is complex and irreproducible. This study focused on the fibromuscular layer and evaluated whether the presence or absence of penetrating fibromuscular invasion of DCC contributes to recurrence and prognosis. In total, 55 patients pathologically diagnosed with DCC who underwent surgical resection from 2002 to 2022 were clinicopathologically examined. Subserosal layer and/or pancreatic (SS/Panc) invasion, defined as penetration of the fibromuscular layer and invasion of the subserosal layer or pancreas by the cancer, was assessed with other clinicopathological prognostic factors to investigate recurrence and prognostic factors. According to the AJCC 8th edition, there were 11 T1, 28 T2, and 16 T3 cases, with 44 (80%) cases of SS/Panc invasion. The DOI was not significantly different for both recurrence and prognostic factors. In the multivariate analysis, only SS/Panc was identified as an independent factor for prognosis (hazard ratio: 16.1; 95% confidence interval: 2.1-118.8, p = 0.006). In conclusion, while the determination of DOI in DCC does not accurately reflect recurrence and prognosis, the presence of SS/Panc invasion may contribute to the T-staging system.

Abstract
BACKGROUND Ruptured aneurysm is a serious complication of distal pancreatectomy (DP) or pancreatoduodenectomy (PD) that can be life-threatening if not treated promptly. This study aimed to examine the efficacy of a Viabahn stent graft for stopping bleeding after pancreatectomy. METHODS Between April 2016 and June 2022, we performed 245 pancreatectomies in our institution. Six patients experienced postoperative bleeding and underwent endovascular treatment. RESULTS All six cases of bleeding occurred post-PD (3.7%). The bleeding was from gastroduodenal artery (GDA) pseudoaneurysms in three patients, and Viabahn stent grafts were inserted. All three patients did not show liver function abnormalities or hepatic blood flow disorders. One patient with a Viabahn stent graft experienced rebleeding, which required further management to obtain hemostasis. Of the six cases in which there was hemorrhage, one case of bleeding from the native hepatic artery could not be managed. CONCLUSIONS Using the Viabahn stent graft is an effective treatment option for postoperative bleeding from GDA pseudoaneurysms following PD. In most cases, using this device resulted in successful hemostasis, without observed abnormalities in hepatic function or blood flow.

Abstract
Aim Nonalcoholic fatty liver disease (NAFLD) can occur due to various reasons after pancreaticoduodenectomy (PD). This study examined the risk and perioperative determinants of NAFLD and fat deposition after PD. Methods A total of 101 patients who had undergone computed tomography 6 months after PD were included. We compared perioperative factors between patients who developed NAFLD and those who developed fatty deposits after PD. Results In the NAFLD group, pancreatic cancer was significantly more prevalent among patients who developed postoperative NAFLD (p = 0.024) and had a lower postoperative body mass index (BMI; p = 0.008). Multivariate analysis revealed that pancreatic carcinoma (hazard ratio [HR] 4.42, 95% confidence interval [CI] 1.118-17.442, p = 0.034) and lower postoperative BMI (HR 0.51, 95% CI 0.274-0.954, p = 0.0355) were risk factors for fatty liver. Pancreatic leakage (p = 0.024) and postoperative BMI (p = 0.002) were significantly lower in the fat deposition group than those in the NAFLD group. Multivariate analysis also revealed that a lower postoperative BMI was a risk factor for fat deposition (HR 0.56, 95% CI 0.523-0.982, p = 0.042). Moreover, multivariate analysis revealed that the fat deposition group had significantly lower pancreatic leakage than the NAFLD group (HR 7.944, 95% CI 1.993-63.562, p = 0.049). Conclusion The findings of this study suggest that postoperative BMI and pancreatic cancer are associated with a higher risk of NAFLD after PD, possibly because of pancreatic exocrine insufficiency and impaired fat absorption.

Abstract
The utility of endoscopic ultrasound fine-needle aspiration cytology (EUS-FNAC) or endoscopic ultrasound fine-needle aspiration biopsy (EUS-FNAB) for diagnosis of small and large pancreatic ductal adenocarcinomas (PDACs) remains in question. We addressed this by analyzing 97 definitively diagnosed cases of PDAC, for which both EUS-FNAC and EUS-FNAB had been performed. We subclassified the 97 solid masses into small (n = 35) or large (n = 62) according to the maximum tumor diameter (<24 mm or ≥24 mm) and compared the diagnostic sensitivity (truly positive rate) of EUS-FNAC and of EUS-FNAB for small and large masses. Diagnostic sensitivity of EUS-FNAC did not differ between large and small masses (79.0% vs. 60.0%; p = 0.0763). However, the diagnostic sensitivity of EUS-FNAB was significantly higher for large masses (85.5% vs. 62.9%; p = 0.0213). Accurate EUS-FNAC-based diagnosis appeared to depend on the degree of cytological atypia of cancer cells, which was not associated with quantity of cancer cells. The accuracy of EUS-FNAB-based diagnosis appeared to depend on cancer cell viability in large masses and cancer volume in small masses. Based on the advantages or disadvantages in each modality, both modalities play an important role in the qualitative diagnosis of PDAC as a complementary procedure.

Abstract
Background As the second-line chemotherapy for stage IV recurrent or nonresectable colorectal cancer, our hospital started a modified treatment regimen comprising of irinotecan plus S-1 (IRIS) [tegafur/gimeracil/oteracil (S-1)] plus molecular targeting agents (MTAs), i.e., an epidermal growth factor receptor (EGFR) inhibitor such as panitumumab (P-mab) or cetuximab (C-mab) or vascular endothelial growth factor (VEGF) inhibitor such as bevacizumab (B-mab) since October 2012. The purpose of this study is to evaluate the efficacy and safety of this modified regimen. Methods This retrospective study included 41 patients with advanced recurrent colorectal cancer at our hospital whom at least 3 courses of chemotherapy were conducted from January 2015 to December 2021. Based on the location of the primary tumor, patients were classified into two group (right-sided group, proximal to the splenic curve, and left-sided, distal to the splenic curve). We assessed archived data on RAS and BRAF status and UGT1A1 polymorphisms and use of the VEGF inhibitor bevacizumab (B-mab) and the EGFR inhibitors panitumumab (P-mab) and cetuximab (C-mab). In addition, progression-free survival rate (36M-PFS) and the overall survival rate (36M-OS) were calculated. Furthermore, the respective median survival time (MST), the median number of treatment courses; the objective response rate (ORR) and clinical benefit rate (CBR) and the incidence of adverse events (AEs) were assessed as well. Results There were 11 patients (26.8%) in the right-sided group, and 30 patients (73.2%) in the left-sided group. There were 19 patients with RAS wild type (46.3%) (1 in the right sided group and 18 in the left sided group). P-mab was used for 16 of these patients (84.2%), C-mab for 2 (10.5%), and B-mab for 1 (5.3%); the remaining 22 patients (53.7%). Ten patients in the right group and 12 patients in the left group were a mutated type and received B-mab. BRAF testing was performed in 17 patients (41.5%); as more than 50% of patients (58.5%) were included before the assay's introduction. Five patients in the right-sided group and 12 patients in the left-sided group had wild type. There was no mutated type. UGT1A1 polymorphism was tested in 16/41 patients: Eight were wild type (8/41 patients, 19.5%) and 8, mutated type. Regarding the *6/*28 double heterozygous type, there was only 1 patient in the right-sided group and the remaining 7 patients were in the left-sided group. The total number of chemotherapy courses was 299, and the median number, 6.0 (range, 3-20). PFS, OS, and MST were as follows: 36M-PFS (total/Rt/Lt), 6.2%/0.0%/8.5% (MST; 7.6/6.3/8.9 months); and 36M-OS (total/Rt/Lt), 32.1%/0.0%/44.0% (MST; 22.1/18.8/28.6 months). The ORR and CBR were 24.4% and 75.6%, respectively. The majority of AEs were grades 1 or 2 and were improved with conservative treatment. Grade 3 leukopenia was observed in 2 cases (4.9%), neutropenia in 4 cases (9.8%), and malaise/nausea/diarrhea/perforation in 1 case each (2.4%). Grade 3 leukopenia (2 patients) and neutropenia (3 patients) were more commonly observed in the left-sided group. Diarrhea and perforation were also common in the left-sided group. Conclusions This second-line modified IRIS regimen with MTAs is safe and effective and results in good PFS and OS.

Abstract
The new isotope ^{241}U was synthesized and systematic atomic mass measurements of nineteen neutron-rich Pa-Pu isotopes were performed in the multinucleon transfer reactions of the ^{238}U+^{198}Pt system at the KISS facility. The present experimental results demonstrate the crucial role of the multinucleon transfer reactions for accessing unexplored neutron-rich actinide isotopes toward the N=152 shell gap in this region of nuclides.

Abstract
Microscopic polyangiitis (MPA) is a necrotizing vasculitis characterized by anti-neutrophil cytoplasmic antibody against myeloperoxidase. The C5 receptor inhibitor avacopan effectively sustains remission in MPA with a reduction in prednisolone dosage. Liver damage is a safety concern for this drug. However, when it occurs and how to treat it remains unknown. A 75-year-old man developed MPA and presented with hearing impairment and proteinuria. Methylprednisolone pulse therapy followed by 30 mg/day prednisolone and two doses of weekly rituximab were administered. Avacopan was initiated to taper prednisolone for sustained remission. After nine weeks, liver dysfunction and sparse skin eruptions developed. Cessation of avacopan and initiation of ursodeoxycholic acid (UDCA) improved liver function without discontinuation of prednisolone and other concomitant drugs. After three weeks, avacopan was rechallenged with a small dose which was gradual increased; UDCA was continued. Full-dose avacopan did not induce recurrence of liver injury. Therefore, gradually increasing the dose of avacopan with concomitant UDCA use may help avoid possible avacopan-induced liver injury.

Abstract
PURPOSE This study compared the pros and cons of two post-distal gastrectomy (DG) reconstruction methods by comparing the patient quality of life and functional dynamics at one year postoperatively. METHODS We compared functional outcomes between Billroth I following laparoscopic 1/2 DG (L-B1; n = 27) and Roux en Y following laparoscopic 4/5 DG (L-RY; n = 24), including laparoscopic total gastrectomy (L-TG; n = 25), at one year postoperatively. Clinical investigations were performed in each patient, and functional evaluations by the acetaminophen (AAP) absorption test and plasma gastrointestinal hormone measurements were performed in consenting patients in each group (L-B1: n = 10, L-RY: n = 10, L-TG: n = 5). RESULTS Postoperative/preoperative body weight ratios were significantly higher in the L-B1 and L-RY groups, in descending order than the L-TG group, although the meal intake ratio was not significantly different between the L-B1 and L-RY groups. The incidence of remnant gastritis was significantly higher in the B1 than in the RY group. AAP levels, glucose and glucagon-like peptide 1 were significantly lower in the L-B1 than in the L-RY group. Active ghrelin levels (AGL) were similar between the L-B1 and L-RY groups. CONCLUSIONS L-B1 maintains gradual intestinal absorption and physiological meal passage and prevents postoperative weight loss. L-RY results in maintenance of the postoperative meal intake via high AGL, equivalent to that in the L-B1 group.

Abstract
BACKGROUND Recent advancements in molecularly targeted chemotherapy for stage IV colorectal cancer have enabled the possibility of complete resection in primary colorectal cancer, which often involves distant liver or lung metastases, by aggressive surgical resection followed by multi-combination chemotherapy. CASE DESCRIPTION A 73-year-old man treated previously for hyperuricemia, hypertension, and a dissecting abdominal aortic aneurysm was referred to us after an incidental finding of multiple liver masses on abdominal ultrasound during follow-up for the aneurysm. A detailed examination by contrast-enhanced computed tomography revealed a ring-enhancing mass larger than 5 cm in diameter in segment 3 of the liver and more than 6 low-density areas with total diameter of 1 to 2 cm in both lobes. A barium enema examination revealed a Borrmann type 2 lesion covering two-thirds of the circumference of the colon, with a 5-cm major axis in the rectosigmoid colon. Biopsy revealed a well-differentiated adenocarcinoma. The patient was diagnosed with stage IV rectal cancer. Because there was no intestinal obstruction, we administered 9 cycles of bevacizumab with capecitabine and oxaliplatin as chemotherapy. Subsequent diagnostic imaging revealed the metastatic lesions in liver segment 3 had reduced to 2 low-density areas with a diameter of 8 mm, and the other hepatic metastases had disappeared; the main tumor had flattened and shrunk. Therefore, we used hand-assisted laparoscopic surgery (HALS) to perform anterior resection of the rectosigmoid colon and partial resection of liver segment 3 as conversion therapy. The patient was discharged 10 days after surgery. The rectal lesion was a well-differentiated adenocarcinoma with a depth of invasion of p-MP and a spread of L0, V0, and pN0. The partial hepatectomy did not indicate viable cancer cells; only necrotic, lysed tissue was observed. Postoperative chemotherapy involved 4 cycles of bevacizumab with capecitabine and oxaliplatin. At more than 42 months postoperatively, no metastasis or recurrence has been observed. CONCLUSIONS This rare case demonstrates that conversion surgery can be a viable option following systemic chemotherapy in patients with advanced colon cancer and H3 liver metastases.

Abstract
BACKGROUND Pancreatic fistula is the most problematic complication in pancreatectomy. Although drainage can be used to relieve this complication, pancreatic surgeons often encounter refractory pancreatic fistula. Fibrin glue injection, with the use of a twofold diluted solution B and a double-lumen tube, was found effective in treating this complicated pancreatic fistula. CASE PRESENTATION We report the case of a 64-year-old Japanese man who underwent laparoscopic distal pancreatectomy for pancreatic tail cancer. After initial drainage of the pancreatic fistula diagnosed 4 days postoperatively, on day 134, refractory pancreatic fistula was observed using contrast-enhanced computed tomography. We used fibrin glue injection, with a twofold diluted solution containing thrombin and calcium chloride and a double-lumen tube, for treating the refractory fistula; the fluid drainage was almost stopped with no fever or abdominal pain. No recurrence of pancreatic cancer has been observed since the procedure. CONCLUSIONS Fibrin glue injection was effective for complicated pancreatic fistula after distal pancreatectomy. Using a twofold diluted solution B containing thrombin and calcium chloride and a double-lumen tube makes possible the thorough injection of fibrin glue.

Abstract
The purpose of this study was to develop a robotic hand to assist with large organs, instead of using a surgeon, in laparoscopic surgery. Grasping, pinching, and exclusion were performed by three subjects with no medical knowledge. The results indicate that the proposed system can perform surgical operations in hand-assisted laparoscopic surgery when the subjects are proficient. However, the thumb mechanism and the wrist control method were required improvement because it was difficult to approach organs. Surgeons were asked to operate the robotic hand while watching the laparoscope image, and they were able to grasp and pinch with little practice.

Abstract
OBJECTIVE Genome-wide association studies (GWAS) have identified >100 risk loci for systemic lupus erythematosus (SLE), but the disease genes at most loci remain unclear, hampering translation of these genetic discoveries. We aimed to prioritise genes underlying the 110 SLE loci that were identified in the latest East Asian GWAS meta-analysis. METHODS We built gene expression predictive models in blood B cells, CD4+ and CD8+ T cells, monocytes, natural killer cells and peripheral blood cells of 105 Japanese individuals. We performed a transcriptome-wide association study (TWAS) using data from the latest genome-wide association meta-analysis of 208 370 East Asians and searched for candidate genes using TWAS and three data-driven computational approaches. RESULTS TWAS identified 171 genes for SLE (p<1.0×10-5); 114 (66.7%) showed significance only in a single cell type; 127 (74.3%) were in SLE GWAS loci. TWAS identified a strong association between CD83 and SLE (p<7.7×10-8). Meta-analysis of genetic associations in the existing 208 370 East Asian and additional 1498 cases and 3330 controls found a novel single-variant association at rs72836542 (OR=1.11, p=4.5×10-9) around CD83. For the 110 SLE loci, we identified 276 gene candidates, including 104 genes at recently-identified SLE novel loci. We demonstrated in vitro that putative causal variant rs61759532 exhibited an allele-specific regulatory effect on ACAP1, and that presence of the SLE risk allele decreased ACAP1 expression. CONCLUSIONS Cell-level TWAS in six types of immune cells complemented SLE gene discovery and guided the identification of novel genetic associations. The gene findings shed biological insights into SLE genetic associations.

Abstract
The Rare-RI Ring (R3) is a recently commissioned cyclotronlike storage ring mass spectrometer dedicated to mass measurements of exotic nuclei far from stability at Radioactive Isotope Beam Factory (RIBF) in RIKEN. The first application of mass measurement using the R3 mass spectrometer at RIBF is reported. Rare isotopes produced at RIBF-^{127}Sn, ^{126}In, ^{125}Cd, ^{124}Ag, ^{123}Pd-were injected in R3. Masses of ^{126}In, ^{125}Cd, and ^{123}Pd were measured whereby the mass uncertainty of ^{123}Pd was improved. This is the first reported measurement with a new storage ring mass spectrometry technique realized at a heavy-ion cyclotron and employing individual injection of the preidentified rare nuclei. The latter is essential for the future mass measurements of the rarest isotopes produced at RIBF. The impact of the new ^{123}Pd result on the solar r-process abundances in a neutron star merger event is investigated by performing reaction network calculations of 20 trajectories with varying electron fraction Y_{e}. It is found that the neutron capture cross section on ^{123}Pd increases by a factor of 2.2 and β-delayed neutron emission probability, P_{1 n}, of ^{123}Rh increases by 14%. The neutron capture cross section on ^{122}Pd decreases by a factor of 2.6 leading to pileup of material at A=122, thus reproducing the trend of the solar r-process abundances. The trend of the two-neutron separation energies (S_{2n}) was investigated for the Pd isotopic chain. The new mass measurement with improved uncertainty excludes large changes of the S_{2n} value at N=77. Such large increase of the S_{2n} values before N=82 was proposed as an alternative to the quenching of the N=82 shell gap to reproduce r-process abundances in the mass region of A=112-124.

Abstract
INTRODUCTION Osteonecrosis of the femoral head (ONFH) involves necrosis of bone and bone marrow of the femoral head caused by ischemia with unknown etiology. Previous genetic studies on ONFH failed to produce consistent results, presumably because ONFH has various causes with different genetic backgrounds and the underlying diseases confounded the associations. Steroid-associated ONFH (S-ONFH) accounts for one-half of all ONFH, and systemic lupus erythematosus (SLE) is a representative disease underlying S-ONFH. We performed a genome-wide association study (GWAS) to identify genetic risk factors for S-ONFH in patients with SLE. METHODS We conducted a two-staged GWAS on 636 SLE patients with S-ONFH and 95 588 non-SLE controls. Among the novel loci identified, we determined S-ONFH specific loci by comparing allele frequencies between SLE patients without S-ONFH and non-SLE controls. We also used Korean datasets comprising 148 S-ONFH cases and 37 015 controls to assess overall significance. We evaluated the functional annotations of significant variants by in-silico analyses. RESULTS The Japanese GWAS identified four significant loci together with 12 known SLE susceptibility loci. The four significant variants showed comparable effect sizes on S-ONFH compared with SLE controls and non-SLE controls. Three of the four loci, MIR4293/MIR1265 (OR = 1.99, P-value = 1.1 × 10-9), TRIM49/NAALAD2 (OR = 1.65, P-value = 4.8 × 10-8) and MYO16 (OR = 3.91, P-value = 4.9 × 10-10), showed significant associations in the meta-analysis with Korean datasets. Bioinformatics analyses identified MIR4293, NAALAD2 and MYO16 as candidate causal genes. MIR4293 regulates a PPARG-related adipogenesis pathway relevant to S-ONFH. CONCLUSIONS We identified three novel susceptibility loci for S-ONFH in SLE.

Abstract
To classify patients with stage III/N2 colorectal cancer into high- and low-risk groups for recurrence, the present study compared clinicopathological features by immunohistochemical staining. The single-center analysis included 53/668 patients (7.9%) with stage III/N2 colorectal cancer who underwent radical resection between January 2006 and December 2014. The present study examined cancer cell distribution in metastatic lymph nodes and classified patients into a group with circumferential localization patterns like a cystic mass (CLP) and a group with scatter patterns like fireworks (SPF). Subsequently, 5-year relapse-free survival (5Y-RFS) and 5-year overall survival (5Y-OS) rates were compared and the histological type (differentiation degree) of the primary adenocarcinoma was included. The CLP group included 16 patients (30.2%) and the SPF group included 37 patients (69.8%). The 5Y-RFS rates in these groups were 75.0 vs. 37.8%, respectively (P=0.021), and the 5Y-OS rates were 81.3 vs. 48.6% (P=0.033). Patient clinicopathological characteristics exhibited no significant differences between groups. The adenocarcinoma was well differentiated in 14 patients (Well; 26.4%) and moderately (Mod; n=37) or poorly (Por; n=2) differentiated in 39 patients (Mod+Por; 73.6%). Patients were further classified into four groups: Well/CLP (n=6), Well/SPF (n=8), Mod+Por/CLP (n=10) and Mod+Por/SPF (n=29). For Well/CLP vs. Well/SPF, the 5Y-RFS rates were 66.7 vs. 25.0%, respectively (P=0.293), and for Mod+Por/CLP vs. Mod+Por/SPF (80.0 vs. 41.4%; P=0.052), the respective values for 5Y-OS were 66.7 vs. 50.0% (P=0.552) and 90.0 vs. 48.3% (P=0.059). Based on the aforementioned results, the CLP group was considered a low-risk group for recurrence with a relatively good prognosis; however, the SPF group was considered a high-risk group for recurrence with a poor prognosis, suggesting a need for more potent multi-combination chemotherapy in these patients from the early postoperative period.

Abstract
We present the case of an elderly female patient with rheumatoid arthritis (RA) treated with methotrexate. She was referred to our hospital with severe malaise. She was emaciated and had massive pleural effusion that induced atelectasis. Her blood tests revealed elevated CRP, leukopenia, and severe anaemia. She lost consciousness on the third day of hospital stay and passed away the following day. Her autopsy showed gelatinous transformation of the bone marrow that gave rise to bicytopoenia, whereas there were no other causes for severe anaemia. Bone marrow gelatinous transformation can cause impaired haematopoiesis in elderly RA patients.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE), an autoimmune disorder, has been associated with nearly 100 susceptibility loci. Nevertheless, these loci only partially explain SLE heritability and their putative causal variants are rarely prioritised, which make challenging to elucidate disease biology. To detect new SLE loci and causal variants, we performed the largest genome-wide meta-analysis for SLE in East Asian populations. METHODS We newly genotyped 10 029 SLE cases and 180 167 controls and subsequently meta-analysed them jointly with 3348 SLE cases and 14 826 controls from published studies in East Asians. We further applied a Bayesian statistical approach to localise the putative causal variants for SLE associations. RESULTS We identified 113 genetic regions including 46 novel loci at genome-wide significance (p<5×10-8). Conditional analysis detected 233 association signals within these loci, which suggest widespread allelic heterogeneity. We detected genome-wide associations at six new missense variants. Bayesian statistical fine-mapping analysis prioritised the putative causal variants to a small set of variants (95% credible set size ≤10) for 28 association signals. We identified 110 putative causal variants with posterior probabilities ≥0.1 for 57 SLE loci, among which we prioritised 10 most likely putative causal variants (posterior probability ≥0.8). Linkage disequilibrium score regression detected genetic correlations for SLE with albumin/globulin ratio (rg=-0.242) and non-albumin protein (rg=0.238). CONCLUSION This study reiterates the power of large-scale genome-wide meta-analysis for novel genetic discovery. These findings shed light on genetic and biological understandings of SLE.

Abstract
Background Neoadjuvant chemotherapy (NAC) has been conducted for patients with non-resectable colorectal cancer; however, few reports of a systematic approach to NAC exist. At our hospital, bevacizumab with capecitabine and oxaliplatin (B-mab XELOX) has been used as chemotherapy for Stage IV colorectal cancer since 2014. We aimed to evaluate the efficacy and safety of NAC with a molecular-targeting agent for Stage IV colorectal cancer. Methods A retrospective, single-institute analysis was performed including 27 patients with advanced recurrent cancer following primary tumor resection and 43 patients with non-resectable tumors and remote metastasis. At the time of resection, 17 were receiving chemotherapy. All 70 patients received at least 3 cycles of B-mab XELOX (total: 920 cycles). We determined the 1-year progression-free survival (1Y-PFS), 1-year overall survival (1Y-OS), 3Y-PFS, 3Y-OS, and number of treatment cycles. The objective response rate, clinical benefit rate, and adverse events were assessed. The number of chemotherapy cycles, survival time, and R0 surgery rate were determined for patients who underwent RO conversion surgery. Results The 1Y-PFS was 28.5% [median survival time (MST): 7.4 months], 1Y-OS was 76.6% (MST not reached), 3Y-PFS was 5.5% (MST: 7.4 months), and 3Y-OS was 26.4% (MST: 25.2 months). The mean and median number of cycles of B-mab XELOX was 13.1 and 10.5, respectively. The objective response rate was 28.6%, and the clinical benefit rate was 58.6%. Grade 1 or Grade 2 adverse events occurred in 60 patients (85.7%); however, they all resolved without intervention. A single Grade 4 event (perforation of the primary tumor) occurred in 1 patient (1.4%). RO conversion surgery was performed in 7 patients (10.0%; primary + liver in 2 patients, primary + lung in 1 patient, liver in 3 patients, and primary in 1 patient). These patients received 3 to 10 cycles preoperatively (mean: 7.3; median: 6.5). R0 surgery was achieved in 5 of the 7 patients (71.4%). Postoperative survival ranged from 1 to 26 months (MST: 8 months). Conclusions This modified regimen was safe and effective in Japanese patients, and a high quality of life/quality-adjusted life-year was achieved. To further evaluate PFS and OS, more patients are being investigated.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has become an urgent global health issue. An older age and underlying conditions, such as diabetes, have been reported as risk factors, but whether or not autoimmune diseases increase the risk remains unknown. An 85-year-old man with Sjögren's syndrome developed a severe COVID-19 infection that required oxygen supplementation. After discussing the goals of care with him and his wife, off-label tocilizumab was given concomitantly, resulting in a rapid improvement in his symptoms and respiratory failure. This patient represents a supplementary case confirming the efficacy and safety of tocilizumab for COVID-19 in elderly patients with autoimmune diseases.

Abstract
Background Recently, due to increasing reports of stenosis after esophagojejunostomy created using circular staplers and a transorally inserted anvil (OrVil™) following laparoscopic proximal gastrectomy (LPG) and total gastrectomy (LTG), linear staplers are being used instead. We investigated our preventive procedure for esophagojejunostomy stenosis following use of circular staplers. Methods Since the anastomotic stenosis is considered to be mainly caused by tension in the esophageal and jejunal stumps at the anastomotic site, we have been performing procedures to relieve this tension, by cutting off the rubber band and pushing the shaft of the circular stapler toward the esophageal side, since July 2015. We retrospectively compared the incidence of anastomotic stenosis in cases of LPG and LTG performed before July 2015 (early phase, 30 cases) versus those performed after this period (later phase, 22 cases). Results Comparison of the incidence of anastomotic stenosis according to the type of surgery, LPG or LTG, and between the two time periods versus all cases, indicated a significantly lower incidence in the later phase than in the early phase (4.5 vs. 26.7%, p < 0.05), especially for LPG (0 vs. 38.5%, p < 0.05). Conclusions It is possible to use a circular stapler during laparoscopic esophagojejunostomy, as with open surgery, if steps to reduce tension on the anastomotic site are undertaken. These procedures will contribute to the spread of safe and simple laparoscopic anastomotic techniques.

Abstract
BACKGROUND Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a non-tumorous benign lesion that originates in the spleen and It is rare. CASE PRESENTATION A 59-year-old man visited his physician for a checkup. Ultrasonography showed a mass in the spleen, and the patient was referred to our hospital. He tested negative for tumor markers and soluble interleukin-2 receptor (sIL-2R). Abdominal computed tomography revealed a 51-mm hypovascular mass that was slowly enhanced from the portal venous to the equilibrium phases, at the inferior extremity of the spleen. Abdominal magnetic resonance imaging showed a spoke-wheel pattern. Fluorodeoxyglucose positron emission tomography indicated a mild tumor accumulation, with a standardized uptake value max of 5.3. These results led to the suspicion of SANT, angioma, and angiosarcoma. Because the onset of malignant diseases could not be excluded, laparoscopic splenectomy was performed. A brown, round mass, without a capsule but with clear boundaries, was macroscopically observed on the cut surface. In addition, white fibrosis was found in the mass. Histopathological examination revealed nodular angioma lesions, and the proliferation of fibrotic interstices and inflammatory cells was observed between the lesions. Immunohistological examination revealed proliferation in the 3 types of narrow capillaries inside angiomatoid nodules;CD31+/CD34+/CD8-, CD31+/CD34-/CD8+, and CD31+/CD34-/CD8- cells; therefore, the patient was diagnosed with SANT. CONCLUSIONS Here, we reported one patient who developed the typical symptoms of SANT. SANT is easily diagnosed by histopathological examination; however, its causes remain unknown. More cases with SANT are required for further analysis.

Abstract
The present study investigated the association between the mode of tumor recurrence and prognosis in 123 patients with clinical stage II/III rectal cancer. In the past 10 years, patients received systemic chemotherapy following radical (R0, with no macroscopic residual tumor lesions) resection using total or tumor-specific mesorectal excision. Patients with rectosigmoid cancer and T4 + chemoradiation therapy were excluded from the present study. The 5-year relapse-free survival rate (5Y-RFS), 5-year overall survival rate (5Y-OS), and associations between early post-operative complications, recurrence mode and prognosis, as well as the 5Y-OS of patients with relapsed cancer, were calculated. The overall 5Y-RFS and 5Y-OS were 71.4 and 83.5%, respectively, and the overall recurrence rate was 22.8% (28/123 patients). Among relapses, remote metastases were observed in 17/123 patients (13.8%): The lung in 8 patients (6.5%), the liver in 5 patients (4.1%) and elsewhere in 4 patients (3.3%). A total of 11 patients (8.9%) had pelvic local recurrence as the first relapse, which was located anterior to the sacrum in 7 patients (5.7%), at the anastomosis site in 2 patients (1.6%), and in the inner pelvis in 2 patients (1.6%). Among relapsed patients, the 5Y-OS was 69.3% in those with distant metastases and 27.3% in those with local relapse (P=0.02; no significant differences in patient demographics). The results indicated that advanced rectal cancer and control of pelvic local recurrence are manageable by R0 resection and postoperative chemotherapy. However, for patients whose initial relapse was pelvic local recurrence, the relapsed tumor initiated a new metastatic cascade to organs, such as the lung and liver, and affected prognosis.

Abstract
Mass-separated ^{187}Ta_{114} in a high-spin isomeric state has been produced for the first time by multinucleon transfer reactions, employing an argon gas-stopping cell and laser ionization. Internal γ rays revealed a T_{1/2}=7.3±0.9 s isomer at 1778±1 keV, which decays through a rotational band with perturbations associated with the approach to a prolate-oblate shape transition. Model calculations show less influence from triaxiality compared to heavier elements in the same mass region. The isomer-decay reduced E2 hindrance factor f_{ν}=27±1 supports the interpretation that axial symmetry is approximately conserved.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NACRT) has not been accepted as a general therapy for gastric cancer because of its localized effect and toxicity for radiosensitive organs. However, if radiation therapy could compensate for the limited or inadequate treatment choices available for elderly patients and/or those at high risk, the available therapeutic options for advanced gastric cancer might increase. From this perspective, we present our experiences of five patients with advanced gastric cancer in whom we used NACRT therapy with interesting results. CASE SUMMARY We admitted five patients with clinical Stage III gastric cancer and bulky lymph node metastasis or adjacent organ invasion at the time of diagnosis. A total of 50 Gy of preoperative intensity modulated radiation therapy was delivered to the patients in doses of 2.0 Gy/d, together with a regimen of concomitant chemotherapy comprising two courses of oral tegafur/gimeracil/oteracil (S-1; 65 mg/m2 per day) for three consecutive weeks followed by two weeks of rest, starting at the same time as radiotherapy. All patients underwent no residual tumor resection and a pathological complete response of the primary tumors was achieved in two patients. The incidence of hematological toxicity was low, although the digestive toxicities of anorexia and diarrhea developed in three of the five patients, necessitating termination of radiation therapy at 30 Gy and S-1 at three weeks. However, even 30 Gy of irradiation and half the dose of S-1 resulted in sufficient downstaging, indicating that even a reduced amount of NACRT could confer considerable effects. CONCLUSION Slightly reduced NACRT might be useful and safe for patients with locally advanced gastric cancer.

Abstract
Eosinophilic granulomatosis with polyangiitis (EGPA) is a relatively rare necrotizing vasculitis that causes asthma, nasal involvement, peripheral nerve disturbance, renal disorder, and cutaneous lesions like purpura and is characterized by eosinophil infiltration into the damaged tissue. Purpura is the most common cutaneous lesion, but it remains unknown whether this skin lesion is associated with disease activity of EGPA and laboratory data including interleukin (IL)-5, a target cytokine of this disease. We conducted a search of our hospital electronic records for cases of EGPA from the last 10 years. Symptoms related to EGPA (fever, asthma, nasal and cutaneous manifestations, neuropathy), the Birmingham Vasculitis Activity Score (BVAS), and laboratory parameters, such as eosinophil count, urinalysis, antineutrophil cytoplasmic antibody (ANCA), CRP, IgE and IL-5, before and during treatment were compared among the eligible cases. A total of 28 EGPA patients (21 females and 7 males) were selected. Almost all developed peripheral neuropathy. Fever occurred in 25%, nasal symptoms in 38.1% and purpura in 44%. Glomerulonephritis developed in 7.7%. One patient had cardiac involvement (3.6%). The laboratory data showed a marked increase in peripheral eosinophil count, CRP, serum IgE and serum IL-5. ANCA was positive in 15.4%. In the univariate analysis, presence of purpura was associated with increased CRP and IL-5, and high BVAS score. Multivariate analysis revealed a robust relationship between purpura and CRP. Our findings showed that presence of purpura was associated with increased CRP and IL-5, and high disease activity in EGPA.

Abstract
The patient was a 72-year-old man who consulted with his previous physician for chief complaints of palpitations, fatigue, and blackish feces persisting for 1 month. After confirming the presence of anemia, the patient was referred to our hospital. Blood test findings upon hospital arrival revealed a hemoglobin (Hb) level of 6.0 g/dL. Computed tomography revealed a tumor of 32 mm × 30 mm with a low-density area extending from the bulb to the second part of the duodenum. Magnetic resonance imaging revealed high signal intensity on T1- and T2-weighted imaging and low signal intensity on fat-suppressed T2-weighted imaging, findings consistent with lipoma. Upper gastrointestinal endoscopy revealed a yellowish submucosal tumor that had perforated into the intestinal tract from the external wall extending from the upper corner to the second part of the duodenum. After determining that the tumor was sessile, laparoscopic partial duodenectomy with Roux-en-Y reconstruction was planned and performed. Pathology revealed a yellowish tumor 4 cm × 4 cm in size extending from the pyloric area to the duodenal bulb arising from the tunica muscularis. The present case report details our experience involving a patient who underwent surgical resection for hemorrhagic duodenal lipoma.

Abstract
Background:Activation of the type I interferon (IFN) pathway has been implicated in the initiation of systemic lupus erythematosus(SLE) and most SLE patients show increased expression of IFN-regulated genes in peripheral blood mononuclear cells or whole blood. However, the IFN signature in lupus kidney is not well examined especially at single cell resolution.Objectives:To clarify the significance of the IFN signature in lupus kidney at single cell resolutionMethods:18 lupus kidney (LN) and 34 transplanted kidney (KTx) samples were included in the study. Residual frozen kidney biopsies were collected after clinical diagnosis. The tissue from one donor was split into two. One portion was used for total RNA-Seq (tRNA-Seq) by SMARTer Stranded Total RNA-Seq Kit v2 - Pico Input Mammalian (Takara/Clontech). The rest was used for single nucleus RNA-Seq (snRNA-Seq) using Chromium Single Cell 3’ Reagent Kits v3 (10x Genomics) (7 LN and 17 KTx). For the tRNA-Seq, the sequence reads were aligned to Ensembl genome annotation (Ens93) by STAR and the aligned reads were counted by htseq. IFN score of tRNA-Seq was calculated using the reported method [1] per each module (M1.2, M3.4 and M5.12). For the snRNA-Seq, the sequenced reads were processed on the standard pipeline of CellRanger (10x Genomics) and the data was visualized using Seurat. IFN score of snRNA-Seq was computed by the method reported by Arazi A,et al[2].Clinical outcomes of LN were examined on the medical records retrospectively and the clinical remission in 56 weeks for LN was defined as a urinary protein/creatinine ratio less than 0.5 g/gCr.Results:11 LN had clinical remission and 7 LN showed non remitted disease within 56 weeks after the biopsy. There were no statistical significance co-variants such as age, gender and WHO class in pathology. IFN score of M1.2, M3.4 and M5.12 were significantly increased in LN with remission within 56 weeks (median 0.773 vs 0.659, 0.595 vs 0.243 and 0.415 vs 0.100: p-value 0.03, 0.01 and 0.02 [Wilcox rank-test]) in tRNA-Seq. In the snRNA-Seq, the lupus kidney with low IFN score showed restricted IFN signature in the endothelial cells mainly, which can be detected even in the controls, but those with high IFN score indicated broadly spread IFN signature among all of the cell types.Conclusion:LN with high IFN score in kidney tissue is correlated with remission within 56 weeks. LN with low IFN score showed IFN signature restricted to endothelial cells but those with a higher IFN score revealed broadly affected cell types with IFN signature. These results suggest that the IFN signature of LN may start from endothelial cells and then spread to the whole kidney.References:[1]Chiche L, Jourde-Chiche N, Whalen E,et al.Modular Transcriptional Repertoire Analyses of Adults With Systemic Lupus Erythematosus Reveal Distinct Type I and Type II Interferon Signatures.Arthritis & Rheumatology2014;66:1583–95.doi:10.1002/art.38628[2]Arazi A, Rao DA, Berthier CC,et al.The immune cell landscape in kidneys of patients with lupus nephritis.Nat Immunol2019;20:902–14.doi:10.1038/s41590-019-0398-xDisclosure of Interests: :Masatoshi Kanda: None declared, Takahiro Tsuji: None declared, Masaya Mukai: None declared, Hiroki Takahashi: None declared, Tatsuya Atsumi Grant/research support from: Eli Lily Japan K.K., Alexion Pharmaceuticals, Inc., Bristol-Myers Squibb Co., AbbVie Inc., Daiichi Sankyo Co., Ltd., Pfizer Inc., Chugai Pharmaceutical Co., Ltd., Mitsubishi Tanabe Pharma Co., Astellas Pharma Inc., Consultant of: Gilead Sciences, Inc., Eli Lilly Japan K.K., UCB Japan Co.

Abstract
Introduction: There are several reports on the use of the over-the-scope clip (OTSC) for gastrointestinal bleeding/fistula and endoscopic iatrogenic perforation. However, there are almost no reports on OTSC use for anastomotic leakage (AL) after colorectal cancer surgery. The purpose of this study was to evaluate the outcome of AL closure using the OTSC.Material and methods: Five patients who had undergone AL after laparoscopic surgery for colorectal cancer from April 2017 to April 2019 were evaluated.Results: The average distance from the anal verge of the anastomosis site was 12 (5-18) cm. The average diameter of the dehiscent part was 10.9 (9.3-14.4) mm. The average number of OTSC days after the occurrence of AL was 11 (5-22). On the contrast examination immediately after OTSC, all cases were completely closed, but in the later contrast examination, only one case remained completely closed. The average incompletely closed diameter was 3.6 (2.9-5.1) mm, and the diameter of the dehiscent part was reduced in all cases. Only one patient ultimately underwent colostomy; the rest were cured with OTSC alone.Conclusion: AL site closure using the OTSC after colorectal cancer surgery is a useful minimally invasive treatment when combined with appropriate drain management.

Abstract
OBJECTIVE This study of 45 patients aimed to retrospectively examine whether the relationships among the postoperative to preoperative body weight ratio (BWR), meal intake as a good indicator of quality of l ife (QOL), and absorptive kinetics from the small intestine could be expressed by the acetaminophen (AAP) concentration. METHODS The postoperative/preoperative BWR and meal intake ratio (MIR) were evaluated in 30 patients who underwent open distal gastrectomy for advanced gastric cancer (ODG group) and 15 patients who underwent laparoscopic proximal gastrectomy for early gastric cancer (LPG group). In addition, all patients underwent functional evaluation using the AAP method. Correlation coefficients of the BWR and MIR with the plasma AAP concentration after meal intake were evaluated. RESULTS There was a negative correlation between the AAP concentration at 15 min and the BWR in all patients (r = -0.438, P = 0.00259, n = 45) and a weak negative correlation between the AAP concentration at 15 min and the MIR (r = -0.309, P = 0.0368, n = 45). CONCLUSIONS There were some relationships between slow intestinal absorption in the early postprandial phase and the maintenance of postoperative body weight and meal intake. Namely, operative methods that maintained preoperative slow intestinal absorption were thought to be better for maintaining postoperative QOL.

Abstract
A 67-year-old woman presented with a chief complaint of umbilical region mass and epigastric pain. Carbohydrate antigen 19-9 (CA19-9) level was 177.5 U/mL; computed tomography (CT) showed a hypovascular mass lesion of 20 mm × 20 mm in the pancreas, infiltration into the superior mesenteric artery and dilation of the main pancreatic duct. Peritoneal dissemination to the omentum and abdominal wall was observed. The patient was diagnosed with T4N0M1, cStage IV unresectable pancreatic body cancer and was started on GEM + nab-PTX therapy. She underwent chemotherapy for 10 months for a total of 10 cycles. The CA19-9 level returned to normal, CT showed reduction in tumor size to 11 mm × 8 mm, and peritoneal dissemination also disappeared. Disappearance of peritoneal dissemination was also observed on Positron emission tomography (PET). Laparoscopic surgery was planned, and rapid pathological examination results of ascites washing cytology and peritoneal mass were negative. Laparoscopic distal pancreatectomy was then performed, which transitioned to hand-assisted laparoscopic surgery; R0 resection was achieved. The patient underwent outpatient postoperative adjuvant chemotherapy with orally administered S-1 and has been recurrence-free for 1 year postoperatively. This case demonstrates that patients with pancreatic body cancer with distant metastasis can undergo R0 resection following GEM + nab-PTX combination therapy.

Abstract
Background Synchronous and asynchronous multiple cancers have become more pervasive in recent years despite advances in medical technologies. However, there have been only six cases (including the present case) that underwent pancreaticoduodenectomy (PD) for pancreas head cancer following surgery for esophageal cancer. PD for treating pancreas head cancer is extremely challenging; thus, the confirmation of vessel variation and selection of surgical procedures are vital. Case presentation The patient was a 78-year-old Japanese male who was synchronously diagnosed with esophageal and cecal cancer 7 years previously at our hospital. He was admitted with densely stained and jaundiced urine and presented no remarkable family medical history. Following various examinations, surgery was performed due to the diagnosis of distal cholangiocarcinoma (pancreatic head cancer). Since the tumor was located far from the gastroduodenal artery (GDA) and no significant lymph node metastases could be found, subtotal stomach-preserving PD was performed instead of the resection of GDA with the right gastroepiploic artery (RGEA) for gastric tube blood flow preservation. The common hepatic artery (CHA) and GDA were confirmed, and RGEA diverged from GDA was identified. Subsequently, their respective tapings were preserved. The right gastric artery (RGA) was identified, taped, and preserved considering the gastric tube blood flow. The inflow area of the right gastroepiploic vein (RGEV) through gastric colic vein trunk in the superior mesenteric vein was exposed and preserved as the outflow of gastric tube blood flow. PD was completed without any complications on the shade of the gastric tube. Conclusions This case report describes successfully preserved gastric blood flow without the resection of GDA, RGEA, RGEV, or RGA. To preserve the gastric tube, GDA inflow, RGEA, RGA, and RGEV outflow should be preserved if possible. When performing PD after tube reconstruction, it is essential to confirm the relative positions of the blood vessel, blood flow, and tumor through three-dimensional computed tomography angiography before surgery and to consider the balance between the invasiveness and optimal curability of the surgery.

Abstract
Background Various body composition indices have been reported as prognostic factors for different cancers. However, whether body composition affects prognosis after lower gastrointestinal tract perforation requiring emergency surgery and multidisciplinary treatment has not been clarified. This study examined whether body composition evaluations that can be measured easily and quickly from computed tomography (CT) are useful for predicting prognosis. Methods Subjects comprised 64 patients diagnosed with perforation at final diagnosis after emergency surgery for a preoperative diagnosis of lower gastrointestinal tract perforation and penetration. They were divided into a survival group and a non-survival (in-hospital mortality) group and compared. Body composition indices (psoas muscle index (PMI); psoas muscle attenuation (PMA); subcutaneous adipose tissue index (SATI); visceral adipose tissue index (VATI); visceral-to-subcutaneous fat area ratio (VSR)) were measured from preoperative CT. Cross-sectional psoas muscle area at the level of the 3rd lumbar vertebra was quantified. Optimal cut-off values were calculated using receiver operating characteristic curve analysis. Poor prognostic factors were investigated from multivariate logistic regression analyses that included patient factors, perioperative factors, intraoperative factors, and body composition indices as explanatory variables. Results The cause of perforation was malignant disease in 12 cases (18.7%), and benign disease in 52 cases (81.2%). The most common cause was diverticulum of the large intestine. Emergency surgery for the 64 patients led to survival in 52 patients and death in 12 patients. On multivariate logistic regression analysis, independent predictors of poor prognosis were Sequential Organ Failure Assessment score (odds ratio 1.908; 95% confidence interval (CI) 1.235–3.681; P = 0.0020) and PMI (odds ratio 13.478; 95%CI 1.342–332.690; P = 0.0252). The cut-off PMI was 4.75 cm2/m2 for males and 2.89 cm2/m2 for females. Among survivors, duration of hospitalization was significantly longer in the low PMI group (29 days) than in the high PMI group (22 days, p = 0.0257). Conclusions PMI is easily determined from CT and allows rapid evaluation of prognosis following lower gastrointestinal perforation.

Abstract
BACKGROUND/AIM Intracorporeal anastomosis (IA) in laparoscopic colectomy for colon cancer is technically difficult, and there is a lack of consensus on the risk of bacterial contamination and cancer cell dissemination. In this study, short- and long-term outcomes of IA were examined. PATIENTS AND METHODS Short and long-term outcomes of those who underwent IA (n=44) or extracorporeal anastomosis (EA) (n=61) were compared. RESULTS IA was better than EA for blood loss, incision length, and first stool. Maximum temperature and C-reactive protein on postoperative day 1 were higher for the IA group. The rate of positive cultures from intraoperative lavage was higher for IA. The rate of positive cultures improved to an equivalent level by replacing mechanical pretreatment with chemical pretreatment. IA and EA were equivalent for the results of ascites cytology from lavage. CONCLUSION With the use of appropriate preoperative treatment, IA takes advantage of the minimally invasive nature of laparoscopic surgery.

Abstract
We demonstrated efficient two-color two-step laser ionization schemes in the combined use of λ1 ∼ 250 nm and λ2 = 307.9 nm, which are applicable to heavy refractory elements with an atomic number in the wide range of Z = 69-78. We investigated newly observed ionization schemes of tantalum and tungsten atoms in an argon-gas-cell-based laser ion source for the efficient ionization of atoms of unstable nuclei through the two-color two-step laser resonance ionization technique. We experimentally determined the ionization cross sections from the measured saturation curves by solving the rate equations for the ground, intermediate, and ionization continuum populations. Hyperfine structures of these elements were also studied to deduce the isotope-shift, pressure-shift, and pressure-broadening in the resonance spectra of the excitation transitions in the argon gas cell. The electronic factor F255 of the excitation transition λ1 = 255.2115 nm between the ground and intermediate states was deduced from the measured isotope shifts of stable 182,183,184,186W isotopes. The ionization schemes investigated here are applicable to extract any isotopes of these elements by considering the measured pressure shift and nuclear isotope shift in optimizing the wavelength λ1.

Abstract
Background Gastric duplication is a relatively rare congenital malformation, accounting for approximately 2.9–3.8% of gastrointestinal duplications. Gastric duplication cyst is a congenital anomaly that is rarely observed in adults. Accurate diagnosis of these cysts before resection is difficult. In this report, we describe a patient with gastric duplication cysts that were treated by laparoscopic resection. Case presentation A 46-year-old Japanese woman was referred to our institution because a cystic lesion in the pancreatic tail was detected by ultrasonography during a health examination. The lesion had a clearly defined boundary of approximately 40 mm. A thick cystic lesion of the septum was observed in the pancreatic tail, but invasion into the stomach wall was not recognized on a computed tomographic scan. Endoscopic ultrasonography revealed that the tumor appeared smooth with a marginal edge, which was characterized by echo with high homogeneity, and the presence of viscous mucus was suspected. The preoperative diagnosis of mucinous cystic neoplasm was the reason for laparoscopic tumor resection. The resected specimen was a smooth surface tumor, and it was full of mucus. Histopathological study revealed that the mucosa was covered with crypt epithelium, muscularis mucosae, intrinsic muscularis, and serosa, and the wall of the tumor had a structure very similar to that of the stomach wall. The mucosa was partially drained by intrinsic gastric glands, but most of them were denucleated. No pancreatic tissue was present, and the tumor had no continuity with the spleen. These findings indicated a diagnosis of gastric duplication cyst with no continuity with the stomach wall. Conclusions In our experience, it is difficult to differentiate gastric duplication cyst from mucinous cystic neoplasm before laparoscopic resection. Events such as infection, bleeding, perforation, ulceration, fistula formation, obstruction, and compression have been linked to gastric duplication cysts, and malignant transformation of these cysts has been reported. Therefore, we suggest that resection should be the first treatment option for gastric duplication cysts.

Abstract
BACKGROUND Colonic diverticulosis is a common disease, and the coexistence of colonic diverticulosis and colorectal cancer is often seen clinically. It is very rare that colon cancer arises from the mucosa of a colonic diverticulum. When colon cancer arises in a diverticulum and then tends to develop outside the wall, without developing within the lumen, the differential diagnosis from complicating lesions due to colonic diverticulitis is difficult.
CASE SUMMARY A 76-year-old man was admitted to a nearby clinic with a chief complaint of discomfort and urinary frequency. Since a vesicosigmoidal fistula was seen on abdominal computed tomography, he was referred to our hospital. Laparoscopic sigmoidectomy was performed because the various diagnostic findings were diagnosed as a vesicosigmoidal fistula with diverticulitis of the sigmoid colon. However, on histopathological examination, it was diagnosed as a vesicosigmoidal fistula due to colon cancer arising in the diverticulum. Laparoscopic partial resection of the bladder was performed because local recurrence was observed in the bladder wall one and a half years after surgery. It is currently one year after reoperation, but there has been no recurrence or metastasis.
CONCLUSION Colon cancer arising in a diverticulum of the colon should be considered when diverticulitis with complications is observed.

We report a case of high-grade pancreatic intraepithelial neoplasia (PanIN) concomitant with lymphoplasmacytic sclerosing pancreatitis. The patient was an 82-year-old man in whom narrowing of the main pancreatic duct was detected incidentally by abdominal ultrasonography. Magnetic resonance cholangiopancreatography further revealed abrupt narrowing plus distal dilatation of the duct, from the pancreatic body to the tail. Distal pancreatectomy was performed under a preoperative diagnosis of intraductal papillary-mucinous neoplasm. Macroscopic examination of the surgical specimen showed an ill-demarcated, white-gray area and prominent pancreatic atrophy, while histological analysis detected small (<5 mm in diameter) cystic dilatations of the main pancreatic duct and some branch ducts plus pancreatic atrophy with fibrosis and fatty replacement of acinar cells. We also detected variously sized papillary projections, fused glands, and scattered focal papillary proliferation of columnar ductal epithelium comprising cells with elongated, mildly hyperchromatic nuclei, consistent with high-grade PanIN. In addition, we observed marked lymphoplasmacytic infiltration, periductal storiform fibrosis, and obliterative phlebitis. Immunohistochemical staining revealed abundant immunogloblin G4-positive plasma cells, indicative of type 1 autoimmune pancreatitis (AIP). The coexistence of high-grade PanIN and marked lymphoplasmacytic infiltration, typical of AIP, point to a close association between the former, as a carcinogenic process, and the latter, as an immune response.

Abstract
Background Biliary system anatomical abnormalities can be preoperatively detected on magnetic resonance imaging; therefore, some presume that the number of bile duct injuries should decline. However, once a bile duct injury occurs, repair may be difficult. There are various ways to repair bile duct injuries, but successful repair may be exceptionally difficult. Case presentation A 72-year-old Japanese man underwent a pancreaticoduodenectomy due to a diagnosis of middle bile duct cancer. We had a complication of an isolated posterior segmental biliary obstruction when pancreaticoduodenectomy was performed. We conducted a drip infusion cholecystocholangiography-computed tomography test to determine the positional relationship between his bile duct and elevated jejunum. To secure the bile duct we punctured the bile duct under computed tomography guidance, and the hepaticojejunal anastomosis site was visualized by inserting an endoscope. We vibrated the bile duct wall by inserting a guide wire through a puncture needle and verified the vibrations with the endoscope. We observed a partially compressed elevated jejunal wall upon guide wire insertion; therefore, we could verify a puncture needle penetration into the elevated jejunum by endoscope on insertion. We also successfully inserted an 8.5-Fr pigtail catheter into the elevated jejunum. We removed all drains after percutaneously inserting an uncovered metallic stent. Our patient’s subsequent clinical course was unremarkable. He visits our institution as an out-patient and has had no stent occlusion even after 6 months. Conclusions When repairing bile duct injuries, it is important to accurately determine the positional relationships between the injured bile duct and the surrounding organs.

Abstract
Previous studies demonstrated that free‑floating cancer cells (FFCCs) in the lymph node sinuses were of prognostic significance for colorectal and gastric cancer. The present study investigated the clinical significance of detecting FFCCs using Fast Red staining for cytokeratin in stage I/II non‑small cell lung cancer (NSCLC) patients and hilar lymph node positive NSCLC patients who underwent curative resection. Between 2002 and 2011, a total of 164 patients (including 22 hilar lymph node positive patients) were investigated. Resected lymph nodes were stained for cytokeratin using an anti‑cytokeratin antibody. In order to achieve a clear distinction from coal dust, an anti‑cytokeratin antibody was labeled with a secondary antibody conjugated with alkaline phosphatase, which was detected by a reaction with Fast Red/naphthol that produced a red color. Patients were considered to be positive for FFCCs (FFCCs+) if one or more than one free‑floating cytokeratin‑positive cell was detected in the lymph node sinuses, which could not be detected by hematoxylin and eosin staining. Among all 164 patients, a significant difference was observed in 5‑year relapse‑free survival (5Y‑RFS) rates, with 76.9 and 33.3% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P<0.001). Similarly, the 5‑year overall survival (5Y‑OS) rate was significantly lower in FFCCs+ patients, with 86.6% being achieved by FFCCs‑ and 65.8% by FFCCs+ patients, respectively (P=0.014). Among 22 hilar lymph node‑positive patients, a significant difference was also observed in 5Y‑RFS, with 53.8 and 0.0% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P=0.006). The 5Y‑OS tended to be lower in FFCCs+ patients, with 69.2 and 53.3% being achieved by FFCCs‑ and FFCCs+ patients, respectively (P=0.463). The findings of the present study suggested the presence of FFCCs in stage I/II NSCLC patients was associated with a poor prognosis. In addition, FFCCs in hilar lymph node‑positive patients may potential be a useful marker in foreseeing the recurrence of cancer.

Abstract
The masses of ^{246}Es, ^{251}Fm, and the transfermium nuclei ^{249-252}Md and ^{254}No, produced by hot- and cold-fusion reactions, in the vicinity of the deformed N=152 neutron shell closure, have been directly measured using a multireflection time-of-flight mass spectrograph. The masses of ^{246}Es and ^{249,250,252}Md were measured for the first time. Using the masses of ^{249,250}Md as anchor points for α decay chains, the masses of heavier nuclei, up to ^{261}Bh and ^{266}Mt, were determined. These new masses were compared with theoretical global mass models and demonstrated to be in good agreement with macroscopic-microscopic models in this region. The empirical shell gap parameter δ_{2n} derived from three isotopic masses was updated with the new masses and corroborates the existence of the deformed N=152 neutron shell closure for Md and Lr.

Abstract
The purpose of the present study was to evaluate the recent trend of diagnosing appendiceal diseases through the analysis of appendectomy materials, stressing the importance of their pathological examination. A clinicopathological assessment of patients undergoing an appendectomy was conducted, based on the pathological examination of resected appendiceal lesions. Using a pathological database of surgical specimens from patients who underwent an appendectomy between March 2002 and September 2014, a retrospective, single-center analysis was performed. Among the 803 patients identified, 752 with appendiceal disease were selected for clinicopathological analysis. The diagnosis was inflammation (i.e. appendicitis) in 97.7% (n=735) and appendiceal neoplasm in 2.3% (n=17) of the patients. The most frequent type of appendiceal neoplasm was an intramucosal neoplasm (23.5%, n=4). In conclusion, the incidence of appendiceal neoplasms has increased in recent years, potentially due to increased and earlier detection by newer imaging modalities.

Abstract
We investigated the reaction dynamics induced by the 7Be,8B+208Pb collisions at energies around the Coulomb barrier. Charged particles originated by both the col- lisions were detected by means of 6 ΔE-Eres telescopes of a newly developed detector array. Experimental data were analysed within the framework of the Optical Model and the total reaction cross-sections were compared together and with the 6,7Li+208Pb colli-sion data. According to the preliminary results, 7Be nucleus reactivity is rather similar to the 7Li one whereas the 8B+208Pb total reaction cross section appears to be much larger than those measured for reactions induced by the other weakly-bound projectiles on the same target.
