Abstract
PURPOSE Colostomy is a common procedure for fecal diversion, but the optimal colostomy approach is unclear in terms of surgical outcomes and stoma-related complications. The purpose of this study was to examine the efficacy and feasibility of laparoscopic loop colostomy. METHODS This retrospective cohort study included patients who underwent loop colostomy at Shizuoka Cancer Center in Japan between April 2010 and March 2022. Patients were divided into two groups based on surgical approach: the laparoscopic (LAP) and open (OPEN) groups. Surgical outcomes and the incidences of stoma-related complications such as stomal prolapse (SP), parastomal hernia (PSH), and skin disorders (SD) were compared with and without propensity score matching. RESULTS Of the 388 eligible patients, 180 (46%) were in the LAP group and 208 (54%) were in the OPEN group. The male-to-female ratio was 5.5:4.5 in the Lap group and was 5.3:4.7 in the OPEN group, respectively. The median age was 68 years (range, 31-88 years) in the LAP group and 65 years (range, 23-93 years) in the OPEN group, respectively. The LAP group, compared with the OPEN group, had a shorter operative time and lower incidences of surgical site infection (3.9% versus 16.3%, respectively; p < 0.01) and SD (11.7% versus 24.5%, respectively; p < 0.01). There was no significant difference between the LAP and OPEN groups in the incidence of SP (17.3% versus 17.3%, respectively) or PSH (8.9% versus 6.7%, respectively). After propensity score matching, the incidences of surgical site infection and SD were significantly lower in the LAP group than in the OPEN group, while there were no significant differences in the operative time or the incidences of SP and PSH. CONCLUSION Our results suggest that laparoscopic surgery could be beneficial and feasible in loop colostomy.

Abstract
PURPOSE/OBJECTIVE(S) Myeloproliferative neoplasms including primary and secondary myelofibrosis (MF) are a rare spectrum of chronic myeloproliferative disorders in which nearly 90% of patients experience splenomegaly. Importantly, splenic radiotherapy (SRT) may be used in combination with allogeneic stem cell transplant (alloSCT) to improve symptoms related to splenomegaly, though there currently is no consensus SRT dose/fractionation protocol reported in the literature for use in combination with alloSCT. We sought to report our institutional experience utilizing low dose SRT prior to alloSCT in the post-Jakafi era. MATERIALS/METHODS We performed a retrospective review of all patients diagnosed with MF at our institution from 2017-2022 who received reduced intensity alloHCT. Patients who underwent total lymphoid or body irradiation were excluded. Descriptive demographic and clinical characteristics of patients were summarized by means, medians, standard deviations, ranges and proportions as appropriate. RESULTS We identified 39 patients with MF who underwent reduced intensity conditioning (RIC) consisting of fludarabine/melphalan in preparation for alloHCT (median age 64.5, 12/16 males, median follow up 21 months). 16 patients with Jakafi-resistant splenomegaly completed low dose SRT prior to transplant (median spleen size: 24.5cm) with a median dose of 5Gy delivered in 5 fractions. 3D conformal therapy was used for all patients. All patients completed the planned total radiation course without treatment break or dose limiting acute toxicity. Thrombocytopenia was the most reported toxicity (CTCAE v5.0; 2 patients experienced grade 1, 1 patient experienced grade 2). No patients experienced grade 3 or higher acute cytopenias nor required transfusion during radiotherapy. All patients successfully received alloHCT a median of 7 days (range: 2-11) after the completion of SRT with a 94% (15/16) engraftment rate. Median neutrophil recovery (ANC > 500 × 3 days) time was 18 days (range: 13-31); median length of hospital stay was 23 days (range: 20-129). Overall survival was 75% in the SRT cohort (12/16, 2 with persistent disease, 2 due to other causes). Symptom burden data was available for 14/16 patients; 79% (11/14) of patients reported improvement in symptoms associated with splenomegaly or reduction in splenic size on physical examination. CONCLUSION In the largest reported experience of a low dose SRT only cohort to date, we observe low dose SRT is feasible, safe in combination with alloHCT with high engraftment rates, and may reduce symptoms related to splenomegaly thereby improving patient quality of life without compromising transplant related outcomes. A prospective study validating this protocol is currently underway.

Abstract
BackgroundMPO-ANCA-associated vasculitis (MPO-AAV) is a systemic small vessel vasculitis with the production of MPO-ANCA in the serum. This disease develops necrotizing and crescent glomerulonephritis (NCGN) and peritubular capillaritis-mediated interstitial damages in the kidneys, and pulmonary hemorrhage due to capillaritis in the lungs. Recent studies have revealed that neutrophil extracellular traps (NETs) induced by MPO-ANCA are critically involved in its pathogenesis,1 and neutrophil elastase (NE) plays an essential role in the formation of NETs.2 Cathepsin C (CatC) functions as a key enzyme in the activation process of several neutrophil serine proteases (NSPs) such as NE, proteinase 3 and cathepthin G by converting the inactive forms of the NSPs to the active forms by digesting dipeptides at the N-terminus of the enzymes.3ObjectivesAlthough glucocorticoids and immunosuppressive drugs used as the standard of cares can lead remission in MPO-AAV patients, there are remaining unmet medical needs such as severe side effects, resistance to the treatment and relapse. Therefore, development of new therapeutic strategies is awaited. The aim of this study is to demonstrate the efficacy of MOD06051, a novel CatC inhibitor, against MPO-AAV, using an MPO-AAV rat model established previously.4MethodsIn vitro studies: Cathpsins and NE inhibitory activity was measured using recombinant enzymes and fluorescent substrates. Cellular NE activity in the granulocytes differentiated from the primary human bone marrow-derived hematopietic stem cells under the presence or absence of MOD06051 was determined using fluorescent substrates.In vivo studies: 4-week-old Wistar Kyoto (WKY) rats were immunized with human MPO according to Little’s protocol.4 The rats were divided into three groups (n=8 in each group), and vehicle (0.5% methylcellulose) or MOD06051 (0.3 or 3 mg/kg bid) was orally administered every day for 42 days. All rats were euthanized at the end of the study for serological and histological evaluations.ResultsIn vitro studies: MOD06051 inhibited the enzymatic activity of human recombinant CatC with an IC50 value of 1.5 nM, and no other cathepsins nor NE inhibition was observed at 10 μM. The NE activity in primary human granulocytes was suppressed by MOD06051 with an IC50 value of 18 nM.In vivo studies: MPO-ANCA was induced in all groups at the same level. The percentage of affected glomeruli including those with NCGN, NET-forming neutrophils in the peripheral blood and glomeruli, and glomerular neutrophil counts were significantly suppressed by MOD06051 treatment in a dose-dependent manner. Furthermore, hematuria score, urinary NGAL (Neutrophil Gelatinase-Associated Lipocalin), tubular erythrocyte cast counts, and pulmonary hemorrhage foci were significantly decreased in the 3 mg/kg of MOD06051 treated group with the similar trends in 0.3 mg/kg group.ConclusionMOD06051 showed sepcific inhibition of CatC activity. This compound suppressed the serine proteases activation in primary human neutrophils and NET formation in the MPO-AAV model rats, resulting in amelioration of MPO-ANCA-induced tissue destruction, including NCGN and tubular interstitial damages in the kidneys, and disorder of alveolar septal capillaries in the lungs. MOD06051 appears to be a promising agent for treatment of MPO-AAV patients.References[1]Nakazawa D, et al. Nat Rev Rheumatol 15: 91-101, 2019.[2]Papayannopoulos V, et al.

Abstract
A 4-year-old male neutered English bulldog presented for heart murmur evaluation. Echocardiography identified severe pulmonic stenosis (an echocardiography-derived transpulmonary pressure gradient of 100 mmHg), and computed tomography confirmed the presence of an anomalous coronary artery with a prepulmonic course of the left coronary artery arising from the right coronary ostium. Before artificial pulmonic valve implantation, a coronary compression test was performed. A simultaneous aortic root angiogram and pulmonic balloon valvuloplasty revealed complete occlusion of the circumflex branch. Artificial valve implantation was aborted with concern for fatal coronary compression after implantation. Coronary compression testing is a critical component of the evaluation before catheter-based implantation of conduits across the pulmonic valve.

Abstract
We herein report 2 cases of laparoscopic total gastrectomy(LTG)in patient with multiple gastric neuroendocrine tumor (NET)related to multiple endocrine neoplasia type 1(MEN1). Case 1: A 66-year-old female was diagnosed with multiple gastric NET. There was no finding of any other tumor, and parathyroid function was normal. She underwent LTG. Case 2: A 58-year-old female was diagnosed with multiple gastric NET. The patient had a previous history of surgery for pituitary gland tumor. There was no finding of any other tumor, and parathyroid function was normal. She underwent LTG. In our cases, we could perform complete resection of gastric NET by laparoscopic surgery. Multiple gastric NET is a good indication of laparoscopic gastrectomy.

Abstract
A 65-year-old man with bloody stools was diagnosed with sigmoid colon cancer on colonoscopy. A preoperative barium enema and a computed tomography colonography scan showed a medial displacement of his descending colon. The preoperative clinical diagnosis was stage cT1 colon cancer, N0, M0, cStage I . Laparoscopic sigmoidectomy was performed. We found adhesions between the descending colon mesentery and the pelvic wall, and noted that the descending colon was not fused with the retroperitoneum and was shifted to the midline. The patient was diagnosed with persistent descending mesocolon (PDM). PDM is a congenital anomaly of fixation resulting from the failure of the descending colon mesentery to fuse with the parietal peritoneum. Anatomical findings should have been noted during the operation, including the fact that the descending colon artery, sigmoid colon artery, and superior rectal artery often branch radially from the inferior mesenteric artery. It is important to understand the anatomical characteristics of PDM and to improve on existing surgical procedures to ensure safe laparoscopic surgery for these patients.

Abstract
We analyzed whether TUR was feasible in 4 cases of urinary bladder recurrence of sigmoid colon cancer that invaded into the bladder. Case No. 1 involved a 66-year-old male who presented with sigmoid colon cancer that had invaded the urinary bladder; he underwent sigmoidectomy with partial bladder resection. Six months after the operation, a small, protruded lesion in his urinary bladder was detected and TUR was performed. He has been cancer free for 10 years. Case No. 2 involved a 53- year-old female who underwent sigmoidectomy and hepatectomy for her sigmoid colon cancer and liver metastasis. She developed bladder and liver metastases, which were resected. Four months later, she underwent TUR because she developed a small recurrent tumor in the bladder. Since then, she has had no intrapelvic recurrence for 6 years. Case No. 3 was a 44- year-old male who underwent bladder-preserving resection for a sigmoid colon cancer that had invaded his bladder. He developed a relatively large bladder tumor 1 year 6 months later. TUR was performed and he was administered CRT. He has had no recurrences for 2 years 5 months. Case No. 4 was a 68-year-old male who underwent bladder-preserving surgery for a sigmoid colon cancer that had invaded his bladder. Because he developed a recurrence in the bladder, he underwent TUR 3 months later. He developed a recurrence in the bladder again 1 year 7 months later, and he underwent TUR again. Multiple organ metastases became evident and was prescribed chemotherapy for 2 years. From these cases, we conclude that TUR may be a feasible option for small, protruded recurrences in the bladder, but we should not hesitate to perform total cystectomy if the first TUR is unsuccessful.

Abstract
Sarcoidosis is a chronic granulomatous disease that can affect multiple organs. The lungs, eyes, and skin are known to be highly affected organs in sarcoidosis. There have been reports based on random muscle biopsy that 32-80% of systemic sarcoidosis comprises noncaseating granulomas; however, muscle involvement in sarcoidosis is generally asymptomatic and has an unknown frequency. We describe a case of acute to subacute sarcoid myositis of the skeletal and extraocular muscles. Typical ophthalmic involvement (manifested by infiltration of the ocular adnexa, intraocular inflammation, or infiltration of the retrobulbar visual pathways) and extraocular sarcoid myositis (as with the present case) is infrequently reported. It is important to keep in mind the rare yet perhaps underestimated entity of sarcoid myositis, and to utilize muscle biopsy and imaging tests for appropriate diagnosis and management of patients with sarcoidosis.

Abstract
Recent studies have suggested that long-term oxytocin administration can alleviate the symptoms of autism spectrum disorder (ASD); however, factors influencing its efficacy are still unclear. We conducted a single-center phase 2, pilot, randomized, double-blind, placebo-controlled, parallel-group, clinical trial in young adults with high-functioning ASD, to determine whether oxytocin dosage and genetic background of the oxytocin receptor affects oxytocin efficacy. This trial consisted of double-blind (12 weeks), open-label (12 weeks) and follow-up phases (8 weeks). To examine dose dependency, 60 participants were randomly assigned to high-dose (32 IU per day) or low-dose intranasal oxytocin (16 IU per day), or placebo groups during the double-blind phase. Next, we measured single-nucleotide polymorphisms (SNPs) in the oxytocin receptor gene (OXTR). In the intention-to-treat population, no outcomes were improved after oxytocin administration. However, in male participants, Clinical Global Impression-Improvement (CGI-I) scores in the high-dose group, but not the low-dose group, were significantly higher than in the placebo group. Furthermore, we examined whether oxytocin efficacy, reflected in the CGI-I scores, is influenced by estimated daily dosage and OXTR polymorphisms in male participants. We found that >21 IU per day oxytocin was more effective than ⩽21 IU per day, and that a SNP in OXTR (rs6791619) predicted CGI-I scores for ⩽21 IU per day oxytocin treatment. No severe adverse events occurred. These results suggest that efficacy of long-term oxytocin administration in young men with high-functioning ASD depends on the oxytocin dosage and genetic background of the oxytocin receptor, which contributes to the effectiveness of oxytocin treatment of ASD.

Abstract
OBJECTIVES This study evaluated the extent to which oral chronic graft-versus-host disease (cGVHD) consensus assessments are predictive of management across institutions with and without oral medicine (OM) centers, and whether ancillary care guidelines are followed within clinical practice. METHODS Longitudinal oral cGVHD data were abstracted from the cGVHD Consortium, and additional mouth-specific management data were analyzed across five transplant centers. RESULTS Seventy-nine patients with 656 visits were observed for a median of 7.1 months with one visit per follow-up month. Ancillary therapies for oral cGVHD were prescribed for 67% of patients for a median of 0.46 months (per follow-up month) at OM centers and 0.78 months at non-OM centers. Patients treated with ancillary therapy were more likely to have an National Institutes of Health (NIH) mouth score of ≥1 (P < 0.001, odds ratio: 5.1) and mouth pain (P = 0.01, odds ratio: 2.6). The odds ratios of receiving ancillary therapy from OM experts were higher than transplant physicians (53%; P = 0.03). CONCLUSIONS Oral cGVHD consensus assessments corresponding with ancillary therapy use were mouth pain and NIH mouth score, with higher odds ratios of receiving therapy from OM experts. Ancillary care guidelines for oral cGVHD are reflected in academic clinical practice with respect to utilization of recommended prescriptions.

Abstract
The protective efficacy of warfarin for cardiogenic cerebral embolism has been established. However, warfarin is generally administered to only approximately 35% of the atrial fibrillation patients who required warfarin therapy. It has been reported that international normalized ratio (INR) control was carried out appropriately in < 50% of such patients. Therefore, from the viewpoint of prevention of the onset and recurrence of embolism, the maintenance of a stable anticoagulant level is necessary. In warfarin therapy, in addition to INR control, time in therapeutic range (TTR) also markedly affects the efficacy of warfarin therapy. Therefore, we classified patients into two groups on the basis of the cutoff TTR ≥ 65% at which the inhibitory effect of warfarin on stroke has been observed. We aimed to examine the association between INR and TTR with the correction of the therapeutic efficacy of warfarin by analyzing the factors leading to poor TTR control. The most valuable finding of this study is that marked fluctuations of brain natriuretic peptide levels in patients with complication of heart failure was a risk factor for poor TTR control. Identification of the factors leading to the poor TTR control is useful for making the decision to switch to other anticoagulants, such as dabigatran or apixaban, or to continue warfarin by correcting risk factors in atrial fibrillation patients receiving long-term warfarin therapy.

Abstract
We conducted a review of patients undergoing heart transplantation (HT) at our institution for amyloid cardiomyopathy (ACM) between 2008 and 2013. Complete follow-up was available for all patients. Nineteen patients with ACM underwent HT during the study period, accounting for 9.4% of all HT performed at our institution during this period. Amyloid subtype was light chain (AL) in 9 patients and transthyretin (ATTR) in 10 (2 wild-type, 7 familial, 1 unknown). Eight of nine patients with AL amyloidosis began chemotherapy prior to HT, six have resumed chemotherapy since HT, and five have undergone autologous stem cell transplantation. Most recent free light chain levels in AL patients decreased by a median of 85% from peak values. Only one patient developed recurrent graft amyloidosis, occurring at 3.5 years post-HT and asymptomatic. After a median follow-up of 380 days, 17 (89.5%) patients are alive. To our knowledge, this is the largest single-center series reported of ACM patients undergoing HT in the modern era. Our results suggest that acceptable outcomes following HT can be achieved in the short-to-intermediate term and that this is a feasible option for end-stage ACM with careful patient selection and aggressive control of amyloidogenic light chains in AL patients.

Abstract
The development of food science in the near future probably depends on the advance in functional food science, the concept of which was proposed first in Japan nearly 15 years ago. The new science has been internationally distributed and accepted as conceptually being beyond nutrition. In Japan, however, it traced a unique path of progress in the form of a product-driven rather than concept-driven science. Actually, a number of substances and products with potential for disease risk reduction rather than simply for health maintenance have been investigated for their body-modulating functions. Some of them have been applied in practice to the industrialization of functional foods in terms of "foods for specified health uses" legally defined by new legislation. A variety of sophisticated methods have been introduced as well, including the so-called "XYZ" evaluation system, database construction for assessment of the function, and even the DNA microarray technique. The Ministry of Agriculture, Forestry, and Fisheries (MAFF) and the Ministry of Health and Welfare (MHW) also commenced their scientific as well as political activity, with its spread to industries which almost simultaneously began to vigorously investigate functional food products for enlargement of the food market. With all of this as a background, the Japan Liaison of the International Union of Food Science and Technology (IUFoST) hold a function food science symposium on behalf of related scientific bodies including the Japan Section of the International Life Science Institute (ILSI). This paper is an overview compiled from 12 presentations made in the symposium, with the aim of internationally publicizing the activity of functional food science in Japan.

Abstract
Because of radioactive fallout resulting from the Fukushima Daiichi Nuclear Power Plant (NPP) accident, water discharge from many outdoor swimming pools in Fukushima was suspended out of concern that radiocesium in the pool water would flow into farmlands. The Japan Atomic Energy Agency has reviewed the existing flocculation method for decontaminating pool water and established a practical decontamination method by demonstrating the process at eight pools in Fukushima. In this method, zeolite powder and a flocculant are used for capturing radiocesium present in pool water. The supernatant is discharged if the radiocesium concentration is less than the targeted level. The radioactive residue is collected and stored in a temporary storage space. Radioactivity concentration in water is measured with a NaI(Tl) or Ge detector installed near the pool. The demonstration results showed that the pool water in which the radiocesium concentration was more than a few hundred Bq L was readily purified by the method, and the radiocesium concentration was reduced to less than 100 Bq L. The ambient dose rates around the temporary storage space were slightly elevated; however, the total increase was up to 30% of the background dose rates when the residue was shielded with sandbags.

Abstract
The changes in the levels of carbonic anhydrase isozyme III (CA-III) in swine plasma and urine have not been previously determined or reported. CA-III is relatively specific to skeletal muscles, and should therefore be a useful diagnostic marker for muscle diseases. We isolated CA-III from swine muscle tissues and determined CA-III levels in the plasma and urine from both healthy and diseased pigs. The levels of CA-III in the tissues of female swine (age, 3 months) and plasma of young swine (age, 1-5 months) and adult female pigs (age, 2-3 years) were determined using the ELISA system for swine CA-III. The mean (± SD) levels of CA-III in the skeletal muscles were 3.8 ± 3.2 mg/g (wet tissue), and in the plasma, 230 ± 193 ng/ml at 1 month, 189 ± 208 ng/ml at 2 months, 141 ± 148 ng/ml at 3 months, 78 ± 142 ng/ml at 4 months and 53 ± 99 ng/ml at 5 months. The mean level of CA-III in the plasma samples from 2- to 3-year-old pigs was 18 ± 60 ng/ml. CA-III in the plasma samples was found to decrease from 1 month until 3 years of age (p < 0.01). We performed far-western blotting to clarify the cause of the observed decrease in CA-III in plasma. Our results demonstrated that CA-III is bound to the transferrin and albumin. In addition, we determined that the levels of CA-III in plasma and urine samples were higher in diseased swine compared with the healthy pigs.

Abstract
Oral chronic GVHD (cGVHD) is a serious complication of alloSCT. Scales and instruments to measure oral cGVHD activity and severity have not been prospectively validated. The objective of this study was to describe the characteristics of oral cGVHD and determine the measures most sensitive to change. Patients enrolled in the cGVHD Consortium with oral involvement were included. Clinicians scored oral changes according to the National Institutes of Health (NIH) criteria, and patients completed symptom and quality-of-life measures at each visit. Both rated change on an eight-point scale. Of the 458 participants, 72% (n=331) had objective oral involvement at enrollment. Lichenoid change was the most common feature (n=293; 89%). At visits where oral change could be assessed, 50% of clinicians and 56% of patients reported improvement, with worsening reported in 4-5% for both the groups (weighted kappa=0.41). Multivariable regression modeling suggested that the measurement changes most predictive of perceived change by clinicians and patients were erythema and lichenoid, NIH severity and symptom scores. Oral cGVHD is common and associated with a range of signs and symptoms. Measurement of erythema and lichenoid changes and symptoms may adequately capture the activity of oral cGVHD in clinical trials but require prospective validation.

Abstract
Intratumoural steroidogenesis may play a significant role in the progression of prostate cancer (PC) in the context of long-term ablation of circulating testosterone (T). To clarify the mechanism accounting for the progression of PC in a 74-year-old man who had undergone bilateral orchiectomy when he was 5 years old, we performed immunohistochemical studies of androgen receptor (AR) and steroidogenic enzymes in the prostate. We also measured steroid hormone levels in the serum and prostate, as well as mRNA levels of genes mediating androgen metabolism in the prostate. Positive nuclear staining of AR was detected in malignant epithelial cells. The levels of androstenedione (Adione), T, and 5-alpha dihydrotestosterone (DHT) in the serum of the patient were similar to those in PC patients receiving neoadjuvant androgen deprivation therapy (ADT), but were higher in the patient's prostate than in PC patients not receiving ADT. The gene expression of CYP17A1 and HSD3B1 was not detected, whereas that of STS, HSD3B2, AKR1C3, SRD5A1, and SRD5A2 was detected. Moreover, cytoplasmic staining of HSD3B2, AKR1C3, SRD5A1, and SRD5A2 was detected in malignant epithelial cells. Hence, in the present case (a man with primary hypogonadism), steroidogenesis in PC tissues from adrenal androgens, especially dehydroepiandrosterone sulphate, was the mechanism accounting for progression of PC. This mechanism might help elucidate the development of castration-resistant PC.

Abstract
When a polymer solution with volatile solvent is dried, skins are often formed at the surface of the solution. It has been observed that after the skin is formed, bubbles often appear in the solution. We conducted experiments to clarify the relation between the skin formation and the bubble formation. We measured the time dependence of the thickness of the skin layer, the size of the bubbles, and the pressure in the solution. From our experiments, we concluded that i) the gas in the bubble is a mixture of solvent vapor and air dissolved in the solution, ii) the bubble nucleation is assisted by the pressure decrease in the solution covered by the skin layer, and iii) the growth of the bubbles is diffusion limited, mainly limited by the diffusion of air molecules dissolved in the solution.
