Abstract
Background Belt electrode skeletal muscle electrical stimulation (B-SES) is an emerging therapy anticipated to yield more favorable outcomes than conventional neuromuscular electrical stimulation (NMES), owing to its larger stimulation area. However, information on its efficacy and safety in patients with heart failure remains limited. Case presentation A 43-year-old man with a body mass index of 41 kg/m2 was admitted to our hospital for acute heart failure due to dilated cardiomyopathy. The patient required prolonged catecholamine support owing to poor cardiac function, and heart transplantation was considered. We initiated a mobilization program, but the patient's mobility was highly limited due to severe obesity and symptomatic orthostatic hypotension. B-SES was introduced to accomplish weight loss and early ambulation. We applied an intensive monitoring program for safe use and modulated the intensity of B-SES according to physical function. During the B-SES program, the patient's body weight decreased from 89.6 kg to 78.6 kg. Sequential evaluations of body composition and skeletal muscle ultrasonography revealed improved muscle mass, quality, and physical function. Furthermore, we explored the workload of B-SES using expiratory gas analysis. No adverse events were observed during B-SES. Discussion We successfully used B-SES to improve muscle function and morbidity in the treatment of acute heart failure. B-SES could be an option for patients with heart failure who have limited mobility and obesity.

Abstract
OBJECTIVES Linezolid is a last-resort antimicrobial in human clinical settings to treat multidrug-resistant Gram-positive bacterial infections. Mobile linezolid resistance genes (optrA, poxtA, and cfr) have been detected in various sources worldwide. However, the presence of linezolid-not-susceptible bacteria and mobile linezolid resistance genes in Japan remains uncertain. Therefore, we clarified the existence of linezolid-not-susceptible bacteria and mobile linezolid resistance genes in farm environments in Japan. METHODS Enterococci isolates from faeces compost collected from 10 pig and 11 cattle farms in Japan in 2021 were tested for antimicrobial susceptibility and possession of mobile linezolid resistance genes. Whole-genome sequencing of optrA and/or poxtA genes positive-enterococci was performed. RESULTS Of 103 enterococci isolates, 12 from pig farm compost were not-susceptible (2 resistant and 10 intermediate) to linezolid. These 12 isolates carried mobile linezolid resistance genes on plasmids or chromosomes (5 optrA-positive Enterococcus faecalis, 6 poxtA-positive E. hirae or E. thailandicus, and 1 optrA- and poxtA-positive E. faecium). The genetic structures of optrA- and poxA-carrying plasmids were almost identical to those reported in other countries. These plasmids were capable of transferring among E. faecium and E. faecalis strains. The optrA- and poxtA-positive E. faecium belonged to ST324 (clade A2), a high-risk multidrug-resistant clone. The E. faecalis carrying optrA gene on its chromosome was identified as ST593. CONCLUSIONS Although linezolid is not used in livestock, linezolid-not-susceptible enterococci could be indirectly selected by frequently used antimicrobials, such as phenicols. Moreover, various enterococci species derived from livestock compost may serve as reservoirs of linezolid resistance genes carried on globally disseminated plasmids and multidrug-resistant high-risk clones.

Abstract
In aquaculture, bacterial infections in sea animals are treated using antimicrobials. As seafood is frequently consumed in its raw form, seafood contaminated with water-borne antimicrobial-resistant bacteria presents a potential transmission route to humans and can influence food safety. In this study, we aimed to determine the abundance of water-borne bacteria in retail raw seafood and to characterize their antimicrobial resistance profiles. In total, 85 retail raw seafood samples (32 fish, 26 shellfish, 25 mollusks, and two crustaceans) were purchased from supermarkets in Japan, and water-borne bacteria were isolated. The isolated bacterial species predominantly included Vibrio spp. (54.1%) and Aeromonas spp. (34.1%). Vibrio or Aeromonas spp. were isolated from more than 70% of the seafood samples. Tetracycline-, sulfamethoxazole-, and/or trimethoprim/sulfamethoxazole-resistant Vibrio or Aeromonas spp. isolates were detected in seven (21.9%) fish samples (two wild-caught and five farm-raised) harboring tet, sul, and/or dfr genes. Sulfamethoxazole- and trimethoprim/sulfamethoxazole-resistant isolates were only detected in farm-raised fish. Tetracycline and sulfamethoxazole are commonly used in aquaculture. These results suggest that water-borne bacteria like Vibrio and Aeromonas spp. should be the primary focus of antimicrobial-resistant bacteria monitoring to effectively elucidate their spread of bacteria via seafood.

Abstract
The purpose of this study was to clarify the relationship between the Suita score (a prediction model for the development of cardiovascular disease) and body composition in Japanese health check-up subjects (6873 men and 8685 women). The Suita score includes 8 items (age, gender, smoking, diabetes, blood pressure, low-density lipoprotein, high-density lipoprotein, and chronic kidney disease). Factors associated with the Suita score within body composition-related parameters (body mass index (BMI), waist circumference (WC), fat mass index, fat-free mass index, fat mass to fat-free mass ratio (F-FF ratio), and water mass index) as assessed by bioelectrical impedance analysis were examined. The mean age of subjects was 54.8 years in men and 52.8 years in women (p < 0.0001). The mean BMI was 23.9 kg/m2 in men and 21.8 kg/m2 in women (p < 0.0001). Diabetes mellitus was found in 1282 subjects (18.7%) among men and 816 subjects (9.4%) among women (p < 0.0001). The mean Suita score was 42.0 in men and 29.6 in women (p < 0.0001). In multivariate analysis, WC (p < 0.0001), F-FF ratio (p < 0.0001), and water mass index (p < 0.0001) were independent factors linked to the Suita score for both genders. In conclusion, body composition can be associated with the Suita score in Japanese adults receiving health check-ups.

Abstract
We sought to investigate the relationship between insulin resistance (IR) and body composition as assessed by bioelectrical impedance analysis in Japanese health check-up recipients (1186 men and 1441 women). IR was defined as a Homeostasis Model Assessment of IR (HOMA-IR) ≥ 2.5. In body-composition-related parameters, the fat mass index (F index) was defined as fat mass divided by the height squared (kg/m2). The fat-free mass index (FF index) was defined as fat-free mass divided by the height squared (kg/m2). The F index to FF index ratio (F-FF ratio) was defined as the F index divided by the FF index. Factors related to HOMA-IR were examined. The median HOMA-IR was 1.54 in men and 1.30 in women (p < 0.0001). The median F index was 4.9 kg/m2 in men and 6.1 kg/m2 in women (p < 0.0001). The median FF index was 18.2 kg/m2 in men and 15.1 kg/m2 in women (p < 0.0001). The median F-FF ratio was 0.272 in men and 0.405 in women (p < 0.0001). The F-FF ratio was an independent factor associated with HOMA-IR in the multivariate analysis in both genders, while the F index and FF index were not in both genders. In conclusion, fat and skeletal muscle balance can be controlled by IR in Japanese adults.

Abstract
Radical cystectomy is a gold-standard treatment for muscle-invasive bladder cancer. We recently introduced robot-assisted radical cystectomy (RARC) with perioperative enhanced recovery after surgery (ERAS). The medical records of patients with bladder cancer who underwent open radical cystectomy (ORC) or RARC/ERAS at NTT Medical Center Tokyo were retrospectively reviewed to compare the surgical outcomes, hospital stay, and medical costs between groups. Multidisciplinary full ERAS items were provided for the RARC/ERAS group. The median estimated blood losses in the ORC and RARC/ERAS groups were 650 and 100 mL, and the median operative times were 312 and 445 min, respectively. In addition, the median times to liquid food intake in these groups were 6 and 0 days, the median times to first flatus and first defecation were 2 and 1 day, and 3 and 1.5 days, respectively. The rates of postoperative ileus in the ORC and RARC/ERAS groups were 27.5% and 4.5%, and the median postoperative hospital stays was 26.5 and 12 days, respectively. Medical costs excluding surgery were significantly lower in the RARC/ERAS group. In conclusion, RARC/ERAS represents a safe treatment option for muscle-invasive bladder cancer with decreased perioperative complications and lower medical costs.

Abstract
Objective The aim of this study was to investigate the impact of untreated hand diseases on hand grip strength, a value that is commonly used as a diagnostic parameter for sarcopenia and frailty in geriatric populations. We hypothesized that individuals with untreated hand diseases would have lower grip strength than those without hand diseases. Methods A total of 240 individuals aged at least 65 years were recruited and divided into two groups based on the presence or absence of typical hand diseases. Grip strength was compared between the two groups separately for men and women using a t-test, with each group consisting of 60 women or 60 men. Results Both women and men in the hand disease group exhibited significantly lower grip strength than those in the control group. Conclusions These findings suggest that untreated hand diseases have a negative impact on grip strength, and this may introduce bias in the screening or diagnosis of sarcopenia and frailty. It is essential to consider the presence of hand diseases when measuring hand grip strength in older adults.

Abstract
We sought to examine body composition using bioimpedance analysis in patients with metabolic dysfunction-associated fatty liver disease (MAFLD, 2014 males and 949 females). Factors linked to the fat-free mass index (FF index) were examined using univariate and multivariate analysis. An FF index < 18 kg/m2 in males and an FF index < 15 kg/m2 in females were defined as having decreased skeletal muscle mass. The median age and body mass index (BMI) were 55 years and 25.4 kg/m2 in males, and 57 years and 25.4 kg/m2 in females, respectively. The FF index strongly correlated with muscle mass index both in males (r = 0.999) and females (r = 0.999). The prevalence of patients with an FF index < 18 kg/m2 in males and an FF index < 15 kg/m2 in females was well stratified according to age, BMI, severity of FL, and FIB4 index. In the males, in the multivariate analysis, BMI (p < 0.0001), fat mass index (p < 0.0001), and waist circumference (p = 0.0050) were found to be significant factors linked to FF index. In the females, in the multivariate analysis, BMI (p < 0.0001) and fat mass index (p < 0.0001) were found to be significant. In conclusion, fat accumulation as reflected by BMI, which is an easily available marker, could be a useful indicator for the skeletal muscle mass in MAFLD.

Abstract
The rapid identification of specific bacterial pathogens in bovine mastitis is crucial for appropriate antimicrobial treatment. Sequencing of 16S rRNA gene amplicons is a proven, useful strategy for diagnosing bacterial infections. In this study, the use of 16S rRNA analysis with nanopore sequencer for the rapid identification of causative bacteria in bovine mastitis, was evaluated. DNA was extracted from 122 milk samples from cattle with suspected mastitis based on clinical symptoms. 16S rRNA gene amplicon sequencing was conducted using a nanopore sequencer. The efficacy of bacterial identification was verified by comparison with conventional culture methods. Nanopore sequencing identified the causative bacteria with high accuracy within approximately 6 h from the time of sample collection. When the major causative bacteria of bovine mastitis (Escherichia coli, Streptcoccus uberis, Klebsiella pneumoniae, and Staphylococcus aureus) were detected by nanopore sequencing, 98.3% of the results were consistent with identification through conventional culturing methods. 16S rRNA gene analysis using a nanopore sequencer enabled the rapid and accurate identification of bacterial species in bovine mastitis.

Abstract
BACKGROUND Adult patients with moyamoya disease (MMD) may present with mild cognitive dysfunction, even those without evidence of conspicuous brain parenchymal damage. This cognitive dysfunction might be caused by local frontal lobe ischemia. OBJECTIVE To explore the relationship between frontal lobe hemodynamic insufficiency and cognitive dysfunction in patients with MMD. METHODS Thirty adult patients with MMD without conspicuous brain parenchymal damage were retrospectively examined. Patients with MMD with frontal lobe intracerebral steal phenomenon on single photon emission computed tomography were defined as group S (n = 13) and those without it were defined as group P (n = 17). A comparative group comprising patients with unruptured intracranial aneurysm was defined as group C (n = 30). The results of various cognitive and intelligence tests and a composite cognitive score were compared between groups. RESULTS The digit span test forward version ( P = .041), frontal assessment battery ( P = .022), and composite cognitive score ( P = .015) z-scores were significantly lower in group S than group C. Adjusting for sex and age, patients in group S had a significantly lower composite cognitive score compared with those in group C in multiple regression analysis ( P = .037). Executive dysfunction and working memory dysfunction may be involved in the cognitive decline observed in group S. CONCLUSION Mild cognitive dysfunction in MMD was associated with frontal lobe hemodynamic insufficiency. Future studies should examine whether revascularization can improve cerebral hypoperfusion and neurocognitive function in these patients.

Abstract
The dissemination of mcr-harboring Enterobacteriaceae, e.g., Escherichia fergusonii, with resistance to colistin via animal products is a public health concern. In our previous study, E. fergusonii harboring the mcr gene were isolated from 11 pigs and 43 chickens. To understand the spread of mcr-harboring E. fergusonii in Okinawa, Japan, and to gain further insights into how they can be controlled, an antimicrobial susceptibility testing, pulsed-field gel electrophoresis (PFGE), a conjugation test for the transferability of mcr-harboring plasmids, and PCR-based replicon typing (PBRT) were performed using the 54 strains. According to the disk-diffusion and broth microdilution methods, 9 of the 11 strains from pigs and 9 of the 43 strains from chickens had multidrug resistance (MDR). The broth microdilution method showed that all strains were resistant to colistin, and the minimum inhibitory concentration of colistin was 4-16 μg/mL. PFGE suggested identical PFGE types were being transmitted within one pig farm, within one chicken farm, and among several chicken farms. These findings showed that some mcr-harboring E. fergusonii in Okinawa exhibited MDR, and these had spread within farms and between farms. In the mcr gene conjugation test and PBRT, a type IncI2 plasmid replicon was detected in all mcr-1-harboring transconjugants. Therefore, evidence suggests that the IncI2 plasmid is probably involved in the transmission of the mcr-1 gene. It is important to monitor the antimicrobial resistance profile and dissemination of the IncI2 plasmid in mcr-harboring E. fergusonii.

Abstract
Colistin is a last resort antimicrobial used for the treatment of gram-negative bacterial infections. Plasmid-mediated colistin resistance (mcr) genes are a cause of global concern, and, thus far, mcr-1-10 have been identified. In a previous study, we screened mcr-1-5 in Escherichia coli derived from diseased pigs in Japan and reported a high prevalence of mcr-1, -3 and -5. However, the previous report on the prevalence of mcr genes was inaccurate. In the present study, we aimed to clarify the prevalence of all reported variants of mcr in E. coli derived from the diseased pigs, which were previously screened for mcr-1-5. Additionally, we also characterized the mcr-9-positive E. coli , which was detected in this study. We screened mcr in 120 E. coli strains from diseased pigs and mcr-positive E. coli and an mcr-carrying plasmid were also characterized. One mcr-9-positive colistin-susceptible E. coli strain was detected (0.8 %). Plasmid-mediated mcr-9 was transferred to E. coli ML4909 as the recipient strain, and it was located on IncHI2/HI2A plasmid p387_L with other antimicrobial resistance genes (ARGs). The region harbouring ARGs including mcr-9, was similar to that on the Klebsiella pneumoniae chromosome harbouring mcr-9 isolated in Japan. mcr-3, -5 and -9 were detected (4.2 %) in colistin-susceptible strains. mcr-9 was found to be disseminated via the plasmid IncHI2/HI2A p387_L and transferred and inserted into chromosomes via a transposon. Our results suggest that mcr genes should be monitored regularly, regardless of their susceptibility to colistin.

Abstract
Tetracyclines (TCs) are widely used for livestock, and the high prevalence of TC-resistant Escherichia coli in livestock has become a serious concern worldwide. In Japan, the National Action Plan on Antimicrobial Resistance in 2016 aimed to reduce the TC resistance rate in E. coli derived from livestock. Flavophospholipol (FPL), used as a feed additive, has an inhibitory effect on the spread of plasmid-mediated antimicrobial resistance. The number of TC-resistant E. coli was determined in pigs administered TCs and/or FPL to clarify the effect of FPL on reducing the number of TC-resistant E. coli in pigs. TC-resistant E. coli and their plasmids were then analyzed. The pigs were divided into four groups: control, doxycycline (DOXY; a TC), FPL, and a DOXY-FPL combination. Their feces were collected from the nursing period to the day before being transported to the slaughterhouse, followed by estimation of TC-resistant E. coli (colony-forming units [CFU]/g). The number of TC-resistant E. coli increased with the use of DOXY, suggesting that DOXY administration provides a selective pressure for TC-resistant E. coli. Supplementation with FPL as a feed additive significantly suppressed the increase in the number of TC-resistant E. coli, especially during the DOXY administration period. Transfer and growth inhibition analyses were performed for TC-resistant isolates. FPL inhibited the conjugational transfer and growth of a few TC-resistant E. coli isolates. These results suggest that FPL is effective against the spread of TC-resistant E. coli.

Abstract
OBJECTIVES Tetracyclines are used in veterinary medicine for livestock. Tigecycline, a semisynthetic tetracycline derivative, is the last resort antimicrobial used to treat multidrug-resistant gram-negative bacterial infections. The prevalence of variants of mobile tigecycline resistance gene tet(X) in livestock is increasing worldwide. However, the prevalence of Tet(X) among livestock in Japan is obscure. This study was conducted to clarify the prevalence of Tet(X) in pigs in Japan, focusing on isolation and molecular characterisation of plasmid-mediated tet(X)-positive Escherichia coli through retrospective analysis. METHODS We retrospectively screened for tigecycline-resistant E. coli strains isolated from pigs. The tigecycline-resistant strain and tet(X)-harbouring plasmid were characterised. RESULTS The IncW plasmid harbouring the tet(X) variant (previously named as tet(X6)) was detected in one E. coli isolate from pigs (0.8%, 1/120) in 2012. The tet(X) plasmid was transferable by conjugation into the E. coli ML4909 recipient strain. Some mobile gene elements (TnAs3 and ISVsa3) were observed in the region surrounding tet(X). The tet(X)-harbouring plasmid shared a conserved backbone IncW plasmid R388, which is a broad-host-range plasmid. CONCLUSIONS The emergence and spread of tet(X) variants in Enterobacterales poses a public health concern. To the best of our knowledge, this is the first report of the emergence of the IncW plasmid harbouring tet(X). Using tetracyclines in livestock exerts selective pressure on the tet(X) plasmid; therefore, prudent use of tetracyclines is required.

Abstract
Efficient methods for decreasing the spread of antimicrobial resistance genes (ARGs) and transfer of antimicrobial-resistant bacteria (ARB) from livestock manure to humans are urgently needed. Aerobic composting (AC) or anaerobic digestion (AD) are widely used for manure treatment in Japanese dairy farms. To clarify the effects of AC and AD on antimicrobial resistance, the abundances of antimicrobial (tetracycline and cefazolin)-resistant lactose-degrading Enterobacteriaceae as indicator bacteria, copy numbers of ARGs (tetracycline resistance genes and β-lactamase coding genes), and concentrations of residual antimicrobials in dairy cow manure were determined before and after treatment. The concentration of tetracycline/cefazolin-resistant lactose-degrading Enterobacteriaceae was decreased over 1,000-fold by both AC and AD. ARGs such as tetA, tetB, and bla TEM were frequently detected and their copy numbers were significantly reduced by ∼1,000-fold by AD but not by AC. However, several ARG copies remained even after AD treatment. Although concentrations of the majority of residual antimicrobials were decreased by both AC and AD, oxytetracycline level was not decreased after treatment in most cases. In addition, 16S rRNA gene amplicon-based metagenomic analysis revealed that both treatments changed the bacterial community structure. These results suggest that both AC and AD could suppress the transmission of ARB, and AD could reduce ARG copy numbers in dairy cow manure.

Abstract
The emergence of plasmid-mediated colistin resistance genes (mcr), which is occurring in numerous countries, is a worldwide concern, primarily because colistin is a last-resort antibiotic. Compared to E. coli, prevalence of mcr genes in Salmonella is unclear in Japan. Here we screened for mcr-1-5 genes in our collection of Salmonella strains isolated from retail meat products collected in Japan from 2012 through 2016. We found that Salmonella Albany strain 27A-368 encodes mcr-5 and that mcr genes were undetectable among the remaining 202 isolates. The resistance plasmid p27A-368 was transferred by conjugation to S. Infantis and was stably retained as a transconjugant. Whole-genome sequencing revealed that mcr-5 resided on a 115 kb plasmid (p27A-368). The plasmid backbone of p27A-368 is more similar to that of pCOV27, an ESBL-encoding plasmid recovered from avian pathogenic E. coli, rather than pSE13-SA01718 of S. Paratyphi B that encodes mcr-5. Further, mcr-5 is located on a transposon, and its sequence is similar to that of pSE13-SA01718. A phylogenetic tree based on single nucleotide variants implies a relationship between 27A-368 and S. Albany isolated in Southeast Asian countries.

Abstract
Introduction: Eosinophilic granulomatosis with polyangiitis (EGPA) patients with mononeuropathy multiplex often visit orthopedic clinics; however, orthopedic surgeons have limited experience in diagnosing EGPA because of its rarity. We report a case of EGPA that required 1 month to confirm the diagnosis.
Case Report: A 48-year-old woman presented with acute onset numbness in the right lower extremity. She had muscle weakness of the right lower extremity; lumbar spine magnetic resonance imaging showed lumbar disc herniation. Despite conservative treatment, her symptoms worsened. Blood tests showed increased eosinophils and serum IgE. She was diagnosed with EGPA, which should be considered in case of atypical paralytic symptoms.
Conclusion: EGPA is so difficult to diagnose. In our case, the symptoms worsened on the 30th day after the initial visit. She was diagnosed with EGPA by a blood test at the time of admission. If patients with bronchial asthma or a history of allergies develop lumbar radiculopathy or peroneal nerve palsy-like symptoms, EGPA should be considered, and steroid treatment should be initiated early.
Keywords: Eosinophilic granulomatosis with polyangiitis, peroneal nerve palsy, lumbar disc herniation, asthma.

Abstract
A 72‒year‒old man visited our hospital with a chief complaint of epigastralgia. Upper gastrointestinal endoscopy revealed type 3 advanced gastric cancer at the body of the stomach. Following an investigation, he was diagnosed with human epidermal growth factor receptor 2‒positive gastric cancer with invasion to the pancreas as well as the paraaortic lymph node, and multiple liver metastases were also observed. The cancer was judged to be cT4a, N2M1(H1 LYM: No. 16), cStage Ⅳ and thus was considered suitable for chemotherapy. We performed capecitabine plus cisplatin plus trastuzumab therapy. After 3 courses, the primary lesion and swollen lymph nodes decreased in size. After 20 chemotherapy courses, the primary lesion relapsed, so conversion surgery was performed. The patient underwent total gastrectomy, distal pancreatectomy, and partial resection of the liver. We planned to perform adjuvant chemotherapy, but the patient declined it because of anorexia. At 18 months after the operation, recurrence of the tumor was detected at the celiac artery. Chemotherapy was performed as follows: capecitabine plus trastuzumab 10 courses, ramucirumab plus paclitaxel, irinotecan, and nivolumab. However, the patient eventually died 71 months after the first visit.

Abstract
Migratory marine species cross political borders and enter the high seas, where the lack of an effective global management framework for biodiversity leaves them vulnerable to threats. Here, we combine 10,108 tracks from 5775 individual birds at 87 sites with data on breeding population sizes to estimate the relative year-round importance of national jurisdictions and high seas areas for 39 species of albatrosses and large petrels. Populations from every country made extensive use of the high seas, indicating the stake each country has in the management of biodiversity in international waters. We quantified the links among national populations of these threatened seabirds and the regional fisheries management organizations (RFMOs) which regulate fishing in the high seas. This work makes explicit the relative responsibilities that each country and RFMO has for the management of shared biodiversity, providing invaluable information for the conservation and management of migratory species in the marine realm.

Abstract
OBJECTIVES The spread of carbapenemase-producing Enterobacterales (CPE) with colistin resistance is a critical public health issue. We genetically characterized the clinical isolate Enterobacter roggenkampii OIPH-N260, which harboured carbapenemase genes blaIMP-1 and blaGES-5 with multiple resistance genes, including mcr-9 and blaCTX-M-9. METHODS This isolate was characterized by whole-genome sequencing, comparative analysis of resistance plasmids, susceptibility tests, bacterial conjugation, S1-nuclease digested pulsed-field-gel electrophoresis, and Southern blot hybridization. RESULTS The OIPH-N260 isolate exhibited resistance to most β-lactams and colistin. It co-harboured two resistance plasmids, the blaIMP-1- and blaGES-5-encoding IncP6 plasmid pN260-3 and mcr-9- and blaCTX-M-9-encoding IncHI2 plasmid pN260-1. The comparative analysis of pN260-3 indicated that a unique blaIMP-1-surrounding region was inserted into the blaGES-5-encoding plasmid with the mobile element IS26, which plays an important role in the spread of resistance genes. pN260-1 did not possess the mcr-9 expression regulative gene qseBC. Both plasmids were transferable into other bacterial species via conjugation. CONCLUSIONS This is the first study to report not only a blaIMP-1 and blaGES-5 co-encoding plasmid, but also the co-harbouring of another plasmid carrying mcr-9 and blaCTX-M-9 in Enterobacter cloacae complex. The development of advanced resistance via IS26-mediated insertion and the co-harbouring of resistance plasmids highlights the need to monitor for resistance genes in CPE.

Abstract
Trifluridine/tipiracil (TAS-102) is an important chemotherapeutic agent recommended by the Japanese guidelines as third- or fourth-line treatment for colorectal cancer. Some studies have reported that administration of TAS-102 concomitant with bevacizumab prolongs progression-free and overall survival in colorectal cancer. We describe 2 patients treated with a chemotherapeutic regimen comprising TAS-102 concomitant with bevacizumab for recurrent colorectal cancer. No adverse events ≥Grade 3(except for hematotoxicity)were observed in these patients. The patient received several courses of chemotherapy with adjustments of the dose and dosing intervals to prevent neutropenia. Combination therapy using TAS-102 and bevacizumab is a feasible Late-line chemotherapeutic regimen for colorectal cancer.

Abstract
OBJECTIVES Escherichia coli (E. coli) is an indicator of antimicrobial resistance, and some strains of E. coli cause infectious diseases. E. coli sequence type 131 (ST131) - a global antimicrobial-resistant pandemic E. coli clone - is frequently detected in clinical specimens. Antimicrobial-resistant bacteria are monitored via national surveillance in clinical settings; however, monitoring information in non-clinical settings is limited. This study elucidated antimicrobial resistance trends of E. coli and dissemination of ST131 among healthy people in non-clinical settings. METHODS This study collected 517 E. coli isolates from healthy people in Osaka, Japan, between 2013 and 2019. It analysed antimicrobial susceptibility of the isolates and detected the bla and mcr genes in ampicillin-resistant and colistin-resistant isolates, respectively, and the ST131 clone. RESULTS Antimicrobial resistance rates of the bacteria isolated from healthy people in non-clinical settings were lower than for those in clinical settings. The resistance of the isolates to cefotaxime (4.4%) and ciprofloxacin (13.5%) gradually increased during the study period. In 23 cefotaxime-resistant isolates, the most frequent bla genes belonged to the blaCTX-M-9 group, followed by blaCTX-M-1 goup, blaTEM and blaCMY-2. One mcr-1-harbouring colistin-resistant isolate was detected in 2016. The incidence of the E. coli O25b-ST131 clone was approximately 5% until 2015 and 10% after 2016. CONCLUSION Both ciprofloxacin resistance and O25b-ST131 clone frequency increased during the study period. Antimicrobial-resistant bacteria gradually spread in healthy people in non-clinical settings; one reason behind this spread was dissemination of global antimicrobial-resistant pandemic clones.

Abstract
BACKGROUND Antimicrobial resistance to colistin, a widely used feed additive for farm animals across the world, has raised public health concern in recent years. Since July 2018, its use as feed additive has been banned in Japan to reduce the spread of plasmid-based mobilized colistin resistance (mcr) genes and the subsequent development of colistin-resistant bacteria. Evaluating the effects of these measures is required. METHODS We evaluated the effects of colistin use, as a feed additive, on colistin resistance in pigs (n=5) from birth to finishing in the farm. Moreover, to evaluate changes in colistin resistance and mcr gene prevalence in response to colistin withdrawal, E. coli samples derived from pig faeces sourced from the fields of three geographically distinct farms were characterized before and after the withdrawal of colistin as a feed additive. RESULTS Colistin-resistant Escherichia coli in pigs (n=5) increased during the colistin administration period and decreased immediately after its end. In three fields, the colistin resistance rate and prevalence of mcr-1 decreased immediately and significantly after the ban. However, colistin-resistant and mcr-1-positive E. coli were still detected in all three farm fields 12 months after the ban on colistin use. CONCLUSION Agricultural colistin use caused selective pressure that contributed to widespread mcr dissemination in Japan. Colistin resistance and the presence of mcr genes should be continuously monitored in food-producing animals.

Abstract
Nosocomial infections or hospital-acquired infections (HAIs) are common health problems affecting patients in human and animal hospitals. Herein, we hypothesised that HAIs could be spread through human and animal movement, contact with veterinary medical supplies, equipment, or instruments. We used a combination of social network analysis and genotyping techniques to find key players (or key nodes) and spread patterns using Escherichia coli as a marker. This study was implemented in the critical care unit, outpatient department, operation room, and ward of a small animal hospital. We conducted an observational study used for key player determination (or key node identification), then observed the selected key nodes twice with a one-month interval. Next, surface swabs of key nodes and their connecting nodes were analysed using bacterial identification, matrix-assisted laser desorption/ionisation-time of flight mass spectrometry, and pulsed-field gel electrophoresis. Altogether, our results showed that veterinarians were key players in this contact network in all departments. We found two predominant similarity clusters; dendrogram results suggested E. coli isolates from different time points and places to be closely related, providing evidence of HAI circulation within and across hospital departments. This study could aid in limiting the spread of HAIs in veterinary and human hospitals.

Abstract
INTRODUCTION In contrast to the study in other part of the world, information about characteristics of plasmids carrying antimicrobial resistance genes (ARGs) in Enterobacteriaceae derived from environmental water in tropical Asian countries including Thailand is limited. This study, therefore, aimed to gain insight into genetic information of antimicrobial resistance in environmental water in Thailand. METHODS Coliform bacteria were isolated from environmental water collected at 20 locations in Thailand and identified. Then, susceptibility profiles to ampicillin, cefazoline, cefotaxime, kanamycin, ciprofloxacin, sulfamethoxazole, tetracycline, and nalidixic acid were assessed. In addition, antimicrobial resistant genes integrons, and replicon types were analyzed. And furthermore, plasmids carrying blaTEM and tetM were identified by S1-PFGE analysis and confirmed transmissibility by transconjugation experiments. RESULTS In 130 coliform bacteria isolated, 89 were resistant to cefazoline while 41 isolates were susceptible. Cefazoline-resistant coliform bacteria were found to be significantly resistant to cefotaxime and tetracycline as compared to susceptible isolates. Hence, blaTEM and tetM correlating with β-lactam antibiotics and tetracycline, respectively, were analyzed found to co-localize on the IncFrepB plasmids in isolates from pig farms' wastewater by S1-PFGE analysis. And furthermore, transmissibility of the plasmids was confirmed. CONCLUSIONS Results obtained in this study suggested that ARGs in coliform bacteria may have been spreading on the farm via IncFrepB plasmids. Hence, appropriate use of antimicrobials and good hygiene management on the farm are required to prevent the emergence and spread of resistant bacteria.

Abstract
The patient, a male in his 70s, visited our hospital with a chief complaint of general fatigue and weight loss. Upon a detailed examination, he was diagnosed with sigmoid colon cancer, para-aortic lymph node metastases, and multiple liver metastases, for which he was hospitalized due to a poor performance status(PS). FOLFOX therapy was administered as the symptoms caused by the primary lesion were not recognized and his general condition was considered to be poor and thus he was deemed to be inoperable. After completing 2 courses of the chemotherapy, although his PS improved, laparoscopic sigmoidectomy was carried out with colonic stent placement due to the occurrence of an intestinal obstruction as a result of an enlargement of the primary lesion. Following surgery, 2 courses of FOLFOX therapy and 4 courses of FOLFOX plus bevacizumab therapy were administered and he is alive at 5 months after the operation without progression.

Abstract
We herein report 2 cases of gastric cancer treated by S-1 and oxaliplatin combination therapy before later undergoing gastrectomy. The pathological results of both cases demonstrated complete response. Case 1 had a giant tumor which was suspected to have invaded the pancreas. Case 2 was associated with extensive lymph node metastasis. Based on the findings of these 2 cases, preoperative chemotherapy with S-1 and oxaliplatin for advanced gastric cancer shows sufficient efficacy.

Abstract
To better understand the prevalence of fluoroquinolone-resistant Escherichia coli among sheltered companion animals, we conducted a screening study of 38 dogs and 78 cats and investigated the resistance mechanisms and characteristics of the isolates. Fluoroquinolone-resistant E. coli was detected in 18 dogs (47.4 %) and 14 cats (17.9 %). The isolates carried one to four mutations in the gyrA, parC and parE genes of the quinolone resistance-determining region, and the number of mutations was proportional to the MIC for ciprofloxacin. For plasmid-mediated quinolone resistance, aac-(6′)-Ib-cr was detected in nine isolates, qnrS in five isolates and qnrB in one isolate. A relationship between the presence of these genes and MIC for ciprofloxacin was not apparent. Statistical analysis indicated that fluoroquinolone-resistant E. coli was widely distributed among sheltered companion animals with various attributes. This may relate to the wide dissemination of fluoroquinolone resistance among humans and other animals in Japan.

Abstract
The advancement of ICT and affordability of medical sensors enable healthcare data to be obtained remotely. Remote healthcare data is erroneous in nature. Detection of errors for remote healthcare data has not been significantly studied. This research aims to design and develop a software system to detect and reduce such healthcare data errors. Enormous research efforts produced error detection algorithms, however, the detection is done at the server side after a substantial amount of data is archived. Errors can be efficiently reduced if the suspicious data can be detected at the source. We took the approach to predict acceptable range of anthropometric data of each patient. We analyzed 40,391 records to monitor the growth patterns. We plotted the anthropometric items e.g., Height, Weight, BMI, Waist and Hip size for males and females. The plots show some patterns based on different age groups. This paper reports one parameter, height of males. We found three groups that can be classified with similar growth patterns: Age group 20–49, no significant change; Age group 50–64, slightly decremented pattern; and Age group 65–100, a drastic height loss. The acceptable range can change over time. The system estimates the updated trend from new health records.

Abstract
Manure compost has been thought of as a potential important route of transmission of antimicrobial-resistant bacteria (ARB) and antimicrobial resistance genes (ARGs) from livestock to humans. To clarify the abundance of ARB and ARGs, ARB and ARGs were quantitatively determined in tetracycline-resistant Escherichia coli (harboring the tetA gene)-spiked feces in simulated composts. In the simulated composts, the concentration of spiked E. coli decreased below the detection limit at day 7. The tetA gene remained in manure compost for 20 days, although the levels of the gene decreased. Next, to clarify the field conditions of manure compost in Japan, the quantities of tetracycline-resistant bacteria, tetracycline resistance genes, and residual tetracyclines were determined using field-manure-matured composts in livestock farms. Tetracycline-resistant bacteria were detected in 54.5% of tested matured compost (6/11 farms). The copy number of the tetA gene and the concentrations of residual tetracyclines in field manure compost were significantly correlated. These results suggest that the use of antimicrobials in livestock constitutes a selective pressure, not only in livestock feces but also in manure compost. The appropriate use of antimicrobials in livestock and treatment of manure compost are important for avoiding the spread of ARB and ARGs.

Abstract
A 71-year-old male presented with abdominal distension and fever to our hospital. Abdominal CT revealed a huge tumor in abdomen, and non-curative surgery was performed. Peritoneal dissemination was widespread and the tumor invaded the bladder and sigmoid-colon mesenterium. Two months after the initial surgery, CT showed liver metastasis, and oral administration of imatinib mesylate was started. The peritoneal dissemination and liver metastasis showed a decrease, and this was well controlled for 45 months without severe side effects. Abdominal CT revealed peritoneal dissemination in the ileocecum after 43 months since the administration of imatinib. Therefore, sunitinib treatment was initiated. After 3 months of sunitinib administration, the tumor perforated. Emergency operation was performed to resect the ileocecum, and sunitinib was continued for 1 year. In GIST with liver metastasis and peritoneal dissemination, repeated surgical resection combined with chemotherapy is important to improve the patient's survival.

Abstract
Currently, chemotherapy against unresectable advanced gastric cancer is progressing with the development new drugs and due to results of several clinical trials. Here, we reported a case of long-term survival of gastric cancer with multiple liver and lymph node metastases. A 68-year-old man was diagnosed with gastric cancer and Virchow lymph node, para-aortic lymph node, and multiple liver metastases at another hospital. He was referred to our hospital from Yamashita Naika Syokakika. We administrated 4 courses of S-1 plus CDDP. The main tumor and all metastatic lesions were significantly reduced. Subsequently, total gastrectomy, partial liver resection, and left neck and para-aortic lymph node resection(conversion surgery)were performed. The cancer cell was remnant at the main tumor and para-gastric lymph node. No cancer cells were detected in another lesion(R0 resection). Postoperatively, only S-1 was administered. However, 28 months after undergoing gastrectomy, liver metastasis occurred. Therefore, S-1 plus oxaliplatin, paclitaxel plus ramucirumab, and CPT-11 plus CDDP were administered. Liver metastases again increased and decreased, respectively. However, 46 months after gastrectomy, liver metastasis recurred and nivolumab was administered. Subsequently, liver metastases disappeared. At 55 months after gastrectomy, rectal resection was performed against rectal cancer and partial liver resection against liver metastases. Cancer cells were not detected in the resected specimens.

Abstract
Extended-spectrum β-lactamase (ESBL)-producing bacteria are spreading rapidly, posing a threat to human and animal health. Contamination of vegetables with antimicrobial-resistant bacteria or those harboring antimicrobial resistance genes or a combination of both presents a potential route of transmission to humans. Therefore, the aim of this study was to determine the prevalence of these bacteria in fresh vegetables in Japan. A total of 130 samples of fresh vegetables were collected from seven supermarkets in Japan. The predominant genus detected was Pseudomonas spp., including 10 ESBL-producing strains, isolated from 10 (7.7%) of the vegetable samples. Two ESBL genes were detected, blaTEM-116 (n = 7) and blaSHV-12 (n = 3), and some of these strains were resistant to multiple antibiotics. Because vegetables are often consumed raw, those contaminated with ESBL producers could represent an important route of transmission to humans in Japan. Thus, more stringent hygiene measures and monitoring are required to prevent transmission via this source.

Abstract
The emergence and spread of aminoglycoside-resistant bacteria are a public health
concern. The acquisition of the genes encoding 16S rRNA methylases, such as
armA, rmtA, and rmtB, confers
high-level resistance to aminoglycosides. However, the prevalence has not been well
investigated in Japanese veterinary fields. To determine the prevalence of 16S rRNA
methylases in animals, we detected 16S rRNA methylases genes in Gram-negative bacteria
from animals. Here, we report the isolation of rmtB and
armA from two of the 446 Escherichia coli (0.5%) and
one of the 103 Klebsiella spp. isolates (1.0%) from companion animals,
respectively. However, none of the isolations were observed from 2445 E.
coli isolates derived from livestock in Japan. The prevalence of 16S rRNA
methylases in animals, especially in companion animals, should be carefully monitored in
Japanese veterinary fields to avoid the spreading of the genes.

Abstract
In the yeast Saccharomyces cerevisiae, the yeast episomal plasmid (YEp), containing a partial sequence from a natural 2-μm plasmid, has been frequently used to induce high levels of gene expression. In this study, we used Japanese sake yeast natural cir0 strain as a host for constructing an entire 2-μm plasmid with an expression construct using the three-fragment gap-repair method without Escherichia coli manipulation. The 2-μm plasmid contains two long inverted repeats, which is problematic for the amplification by polymerase chain reaction. Therefore, we amplified it by dividing into two fragments, each containing a single repeat together with an overlapping sequence for homologous recombination. TDH3 promoter-driven yEmRFP (TDH3p-yEmRFP) and the URA3 were used as a reporter gene and a selection marker, respectively, and inserted at the 3' end of the RAF1 gene on the 2-μm plasmid. The three fragments were combined and used for the transformation of sake yeast cir0 ura3- strain. The resulting transformant colonies showed a red or purple coloration, which was significantly stronger than that of the cells transformed with YEp-TDH3p-yEmRFP. The 2-μm transformants were cultured in YPD medium and observed by fluorescence microscopy. Almost all cells showed strong fluorescence, suggesting that the plasmid was preserved during nonselective culture conditions. The constructed plasmid maintained a high copy state similar to that of the natural 2-μm plasmid, and the red fluorescent protein expression was 54 fold compared with the chromosomal integrant. This vector is named YHp, the Yeast Hyper expression plasmid.

Abstract
We report a case of unresectable pancreas cancer. A 70-year-old woman presented with worsening diabetes and serum CA19-9 elevation. A tumor with portal vein and supra-mesenteric vein invasion was observed by computed tomography. She was diagnosed with unresectable pancreas head cancer that was locally advanced. Chemotherapy was administered with gemcitabine and nab-paclitaxel for 19 courses, followed by gemcitabine alone for 4 courses. After the addition of 6 courses of chemotherapy, a 60%dose of chemotherapy was administered for 13 courses due to severe neutropenia. The patient died 32 months after the first visit. The 60% dose of gemcitabine and nab-paclitaxel also inhibited tumor growth. These findings suggest the effective and safe long-term use of gemcitabine and nab-paclitaxel.

Abstract
The safety and feasibility of chemotherapy for elderly patients is unclear. We report a super-elderly patient with liver metastases from colorectal cancer successfully treated with capecitabine plus bevacizumab chemotherapy. An 87-year-old woman underwent a colectomy for transverse colon. At 4 months postoperatively, she underwent hepatectomy for liver metastases. At 9 months after the first surgery, a new liver metastases(S4)was found. At this time, she rejected another hepatectomy. Therefore, we selected capecitabine plus bevacizumab chemotherapy, considering her age. After 18 courses of administration, the liver metastasis did not progress, and no new metastatic lesions were found on CT examination. Although as adverse events Grade 2 hand-foot syndrome developed, no other adverse event occurred. The patient's PS score was maintained at 0. We suggest capecitabine plus bevacizumab chemotherapy is an effective regimen for super-elderly patients with colorectal cancer.

Abstract
Background:The electronic prescription system has emerged to reduce the ambiguity and misunderstanding associated with handwritten prescriptions. The opportunities and challenges of e-prescription system, its impact on reducing medication error, and improving patient's safety have been widely studied. However, not enough studies were conducted to explore and quantify the factors that affect rural patients' compliance with e-prescription, especially from the perspective of Asian developing countries where most of the world's population resides. Objective:The objective of this study is to explore and assess the factors that affect rural patients' primary compliance with e-prescription in Bangladesh. Methods:Data were collected from 95 randomly selected rural patients who received e-prescription through a field survey with a structured questionnaire from Bheramara subdistrict, Bangladesh, during June and July 2016. Logistic regression analysis was performed to test the research hypotheses. Results:The study found patients' gender as the most significantly influential factor (regression coefficient [Coef.] = 2.02, odds ratio [OR] = 7.51, p < 0.05) followed by visiting frequency (Coef. = 0.99, OR = 2.70, p < 0.05); education (Coef. = 0.92, OR = 2.51, p < 0.05); and distance to healthcare facility (Coef. = 0.82, OR = 2.26, p < 0.01). However, patients' age, monthly family expenditure, and use of cell phone were found insignificant. The model explains 59.40% deviance (R2 = 0.5940) in the response variable with its constructs. And the “Hosmer–Lemeshow” goodness-of-fit score (0.99) is also above the standard threshold (0.05), which indicates the data fit well with the model. Conclusions:The findings of this study are expected to be helpful for e-health service providers to gain a better understanding of the factors that influence their patients to comply with e-prescriptions.
