Abstract
BACKGROUND Sodium-glucose co-transporter-2 (SGLT2) inhibitors reduce progression of chronic kidney disease and the risk of cardiovascular morbidity and mortality in a wide range of patients. However, their effects on kidney disease progression in some patients with chronic kidney disease are unclear because few clinical kidney outcomes occurred among such patients in the completed trials. In particular, some guidelines stratify their level of recommendation about who should be treated with SGLT2 inhibitors based on diabetes status and albuminuria. We aimed to assess the effects of empagliflozin on progression of chronic kidney disease both overall and among specific types of participants in the EMPA-KIDNEY trial. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA), and included individuals aged 18 years or older with an estimated glomerular filtration rate (eGFR) of 20 to less than 45 mL/min per 1·73 m2, or with an eGFR of 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher. We explored the effects of 10 mg oral empagliflozin once daily versus placebo on the annualised rate of change in estimated glomerular filtration rate (eGFR slope), a tertiary outcome. We studied the acute slope (from randomisation to 2 months) and chronic slope (from 2 months onwards) separately, using shared parameter models to estimate the latter. Analyses were done in all randomly assigned participants by intention to treat. EMPA-KIDNEY is registered at ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and then followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroups of eGFR included 2282 (34·5%) participants with an eGFR of less than 30 mL/min per 1·73 m2, 2928 (44·3%) with an eGFR of 30 to less than 45 mL/min per 1·73 m2, and 1399 (21·2%) with an eGFR 45 mL/min per 1·73 m2 or higher. Prespecified subgroups of uACR included 1328 (20·1%) with a uACR of less than 30 mg/g, 1864 (28·2%) with a uACR of 30 to 300 mg/g, and 3417 (51·7%) with a uACR of more than 300 mg/g. Overall, allocation to empagliflozin caused an acute 2·12 mL/min per 1·73 m2 (95% CI 1·83-2·41) reduction in eGFR, equivalent to a 6% (5-6) dip in the first 2 months. After this, it halved the chronic slope from -2·75 to -1·37 mL/min per 1·73 m2 per year (relative difference 50%, 95% CI 42-58). The absolute and relative benefits of empagliflozin on the magnitude of the chronic slope varied significantly depending on diabetes status and baseline levels of eGFR and uACR. In particular, the absolute difference in chronic slopes was lower in patients with lower baseline uACR, but because this group progressed more slowly than those with higher uACR, this translated to a larger relative difference in chronic slopes in this group (86% [36-136] reduction in the chronic slope among those with baseline uACR <30 mg/g compared with a 29% [19-38] reduction for those with baseline uACR ≥2000 mg/g; ptrend<0·0001). INTERPRETATION Empagliflozin slowed the rate of progression of chronic kidney disease among all types of participant in the EMPA-KIDNEY trial, including those with little albuminuria. Albuminuria alone should not be used to determine whether to treat with an SGLT2 inhibitor. FUNDING Boehringer Ingelheim and Eli Lilly.

Abstract
BACKGROUND The EMPA-KIDNEY trial showed that empagliflozin reduced the risk of the primary composite outcome of kidney disease progression or cardiovascular death in patients with chronic kidney disease mainly through slowing progression. We aimed to assess how effects of empagliflozin might differ by primary kidney disease across its broad population. METHODS EMPA-KIDNEY, a randomised, controlled, phase 3 trial, was conducted at 241 centres in eight countries (Canada, China, Germany, Italy, Japan, Malaysia, the UK, and the USA). Patients were eligible if their estimated glomerular filtration rate (eGFR) was 20 to less than 45 mL/min per 1·73 m2, or 45 to less than 90 mL/min per 1·73 m2 with a urinary albumin-to-creatinine ratio (uACR) of 200 mg/g or higher at screening. They were randomly assigned (1:1) to 10 mg oral empagliflozin once daily or matching placebo. Effects on kidney disease progression (defined as a sustained ≥40% eGFR decline from randomisation, end-stage kidney disease, a sustained eGFR below 10 mL/min per 1·73 m2, or death from kidney failure) were assessed using prespecified Cox models, and eGFR slope analyses used shared parameter models. Subgroup comparisons were performed by including relevant interaction terms in models. EMPA-KIDNEY is registered with ClinicalTrials.gov, NCT03594110. FINDINGS Between May 15, 2019, and April 16, 2021, 6609 participants were randomly assigned and followed up for a median of 2·0 years (IQR 1·5-2·4). Prespecified subgroupings by primary kidney disease included 2057 (31·1%) participants with diabetic kidney disease, 1669 (25·3%) with glomerular disease, 1445 (21·9%) with hypertensive or renovascular disease, and 1438 (21·8%) with other or unknown causes. Kidney disease progression occurred in 384 (11·6%) of 3304 patients in the empagliflozin group and 504 (15·2%) of 3305 patients in the placebo group (hazard ratio 0·71 [95% CI 0·62-0·81]), with no evidence that the relative effect size varied significantly by primary kidney disease (pheterogeneity=0·62). The between-group difference in chronic eGFR slopes (ie, from 2 months to final follow-up) was 1·37 mL/min per 1·73 m2 per year (95% CI 1·16-1·59), representing a 50% (42-58) reduction in the rate of chronic eGFR decline. This relative effect of empagliflozin on chronic eGFR slope was similar in analyses by different primary kidney diseases, including in explorations by type of glomerular disease and diabetes (p values for heterogeneity all >0·1). INTERPRETATION In a broad range of patients with chronic kidney disease at risk of progression, including a wide range of non-diabetic causes of chronic kidney disease, empagliflozin reduced risk of kidney disease progression. Relative effect sizes were broadly similar irrespective of the cause of primary kidney disease, suggesting that SGLT2 inhibitors should be part of a standard of care to minimise risk of kidney failure in chronic kidney disease.

Abstract
Convection-enhanced delivery (CED) delivers agents directly into tumors and the surrounding parenchyma. Although a promising concept, clinical applications are often hampered by insufficient treatment efficacy. Toward developing an effective CED-based strategy for delivering drugs with proven clinical efficacy, we performed a basic characterization study to explore the locally delivered characteristics of the water soluble nitrosourea nimustine hydrochloride (ACNU). First, ACNU distribution after CED in rodent brain was studied using mass spectrometry imaging. Clearance of 14C-labeled ACNU after CED in striatum was also studied. ACNU was robustly distributed in rodent brain similar to the distribution of the hydrophilic dye Evans blue after CED, and locally delivered ACNU was observed for over 24 h at the delivery site. Subsequently, to investigate the potential of ACNU to induce an immunostimulative microenvironment, Fas and transforming growth factor-β1 (TGF-β1) was assessed in vitro. We found that ACNU significantly inhibited TGF-β1 secretion and reduced Fas expression. Further, after CED of ACNU in 9L-derived intracranial tumors, the infiltration of CD4/CD8 lymphocytes in tumors was evaluated by immunofluorescence.CED of ACNU in xenografted intracranial tumors induced tumor infiltration of CD4/CD8 lymphocytes. ACNU has a robust distribution in rodent brain by CED, and delayed clearance of the drug was observed at the local infusion site. Further, local delivery of ACNU affects the tumor microenvironment and induces immune cell migration in tumor. These characteristics make ACNU a promising agent for CED.

Abstract
Yogurt is made by fermenting milk with 2 lactic acid bacteria, Lactobacillus delbrueckii ssp. bulgaricus and Streptococcus thermophilus. To comprehensively understand the protocooperation mechanism between S. thermophilus and L. bulgaricus in yogurt fermentation, we examined 24 combinations of cocultures comprising 7 fast- or slow-acidifying S. thermophilus strains with 6 fast- or slow-acidifying L. bulgaricus strains. Furthermore, 3 NADH oxidase (Nox)-deficient mutants (Δnox) and one pyruvate formate-lyase deficient mutant (ΔpflB) of S. thermophilus were used to evaluate the factor that determines the acidification rate of S. thermophilus. The results revealed that the acidification rate of S. thermophilus monoculture determined the yogurt fermentation rates, despite the coexistence of L. bulgaricus, whose acidification rate was either fast or slow. Significant correlation was found between the acidification rate of S. thermophilus monoculture and the amount of formate production. Result using ΔpflB showed that the formate was indispensable for the acidification of S. thermophilus. Moreover, results of the Δnox experiments revealed that formate production required Nox activity, which not only regulated dissolved oxygen, but also the redox potential. The Nox provided the large decrease in redox potential required by pyruvate formate-lyase to produce formate. A highly significant correlation was found between formate accumulation and Nox activity in S. thermophilus. In conclusion, the formate production ability provided by the action of Nox activity determines the acidification rate of S. thermophilus, and consequently, regulates yogurt coculture fermentation.

Abstract
BACKGROUND After esophagectomy for esophageal and esophagogastric cancer, more than half of patients have lost > 10% of their body weight at 12 months. In most cases, the gastric remnant is used for reconstruction after esophagectomy. One of the most serious nutritional complications of this technique is delayed gastric emptying caused by gastric remnant mobilization and denervation of the vagus nerve. The aim of the PYloroplasty versus No Intervention in GAstric REmnant REconstruction after Oesophagectomy (PYNI-GAREREO) trial is to analyze the clinical outcome of modified Horsley pyloroplasty (mH-P) as a method of preventing delayed gastric emptying. METHODS The PYNI-GAREREO trial is designed as an open randomized, single-center superiority trial. Patients will be randomly allocated to undergo gastric remnant reconstruction with mH-P (intervention group) or no intervention (control group) in parallel groups. All patients with esophageal cancer or esophagogastric cancer planning to undergo curative minimally invasive esophagectomy will be considered for inclusion. A total of 140 patients will be included in the study and randomized between the groups in a 1:1 ratio. The primary outcome is the body weight change at 6 months postoperatively, and the secondary outcomes are the nutritional status, postoperative complications, functional outcome, and quality of life until 1 year postoperatively. DISCUSSION We hypothesize that mH-P after minimally invasive esophagectomy more effectively maintains patients' nutritional status than no pyloroplasty.

Abstract
BACKGROUND We investigated the independent clinical value of mechanical bowel preparations (MBP) and chemical bowel preparations (CBP) for preventing surgical site infection (SSI) in patients undergoing elective laparoscopic colorectal surgery. MATERIALS AND METHODS This retrospective cohort study included 475 patients who underwent elective laparoscopic colorectal surgery between January 2018 and March 2022. CBP was introduced in January 2021 and included kanamycin (1 g) and metronidazole (1 g) 2 times a day, the day before surgery. In some cases, MBP was omitted in patients who planned to undergo right-sided colectomy, those with tumor obstruction, and those with poor general conditions, depending on the judgment of the physician. The primary endpoint was the overall SSI incidence, while the secondary endpoints were the incidences of incisional SSI and organ-space SSI, culture from the surgical site, and length of postoperative hospital stay. RESULTS In total, 136 patients underwent CBP. MBP was omitted in 53 patients. Overall, SSI occurred in 80 patients (16.8%), including 61 cases of incisional SSI (12.8%) and 36 cases of organ-space SSI (7.6%). Multivariate logistic regression revealed that CBP exerted an independent preventive effect on overall and incisional SSI, whereas MBP did not. However, CBP was not associated with a decreased risk of overall SSI in patients who had undergone preoperative therapy, those with benign disease, and those with stoma formation in the subgroup analysis. Levels of Bacteroides species at the surgical site were significantly lower in the CBP group than in the non-CBP group. Postoperative hospital stay was significantly longer in the incisional SSI group than in the non-SSI group and was significantly longer in the organ-space SSI group than in the other groups. CONCLUSIONS CBP, but not MBP, exerts an independent preventive effect on SSI, especially incisional SSI, in patients undergoing elective laparoscopic colorectal surgery.

Abstract
BACKGROUND/AIM Currently, only a small part of functional lymphatic flow around the anorectal region has been anatomically analyzed. Despite the fact that local recurrence is often experienced in the pelvic floor, the functional lymphatic network in this region has rarely been studied due to difficulties in observation. This prospective observational study aimed to observe anorectal lymphatic flow around the pelvic floor using intraoperative indocyanine green fluorescence imaging during laparoscopic or robot-assisted rectal surgery. PATIENTS AND METHODS Fourteen patients who underwent laparoscopic (n=7) or robot-assisted (n=7) surgery without any preoperative therapy between April and December 2022 were enrolled. Indocyanine green solution (0.25 mg) was injected into the submucosa at the dentate line of the anterior, posterior, and bilateral walls prior to surgery. During and after total mesorectal excision, lymphatic flow was observed using a near-infrared camera system. RESULTS Lymphatic flow visualized by indocyanine green was detected not only in the already-known route from the low rectum to the lateral pelvic lymph nodes via the lateral ligament, but also in the novel route from the low rectum to the surface of the levator ani muscle and hiatal ligament. Fluorescence was widely spread in the pelvic floor between the longitudinal muscle of the low rectum and the surface of the levator ani muscle. CONCLUSION Even though the results are preliminary since histological analyses were not performed, a novel widespread lymphatic network on the surface of the levator ani muscle originating from the longitudinal muscle fibers of the low rectum was revealed.

Abstract
IntroductionAttention-deficit/hyperactivity disorder (ADHD) is a neuropsychiatric disorder whose primary symptoms are hyperactivity, impulsivity, and inattention. Historically, ADHD was recognized as a disease of childhood and adolescence. However, many patients are known to have persistent symptoms into adulthood. Many researchers consider the neuropathology of ADHD to be based on abnormalities in multiple parallel and intersecting pathways rather than a single anatomical area, but such alterations remain to be clarified.MethodsUsing diffusion tensor imaging, we investigated differences in the global network metrics estimated by graph theory and the degree of connectivity between adjacent voxels within a white matter (WM) fascicle defined by the density of the diffusing spins (connectometry) between 19 drug-naive Japanese patients with adult ADHD and 19 matched healthy controls (HCs). In adult patients with ADHD, we examined the relationships between the symptomatology of ADHD and global network metrics and WM abnormalities.ResultsCompared with HCs, adult patients with ADHD showed a reduced rich-club coefficient and decreased connectivity in widely distributed WMs such as the corpus callosum, the forceps, and the cingulum bundle. Correlational analyses demonstrated that the general severity of ADHD symptoms was associated with several global network metrics, such as lower global efficiency, clustering coefficient, small worldness, and longer characteristic path length. The connectometry revealed that the severity of hyperactive/impulsive symptoms was associated with overconnectivity in the corticostriatal, corticospinal, and corticopontine tracts, the inferior fronto-occipital fasciculus, and the extreme capsule but dysconnectivity in the cerebellum. The severity of inattentive symptoms was associated with dysconnectivity in the intracerebellar circuit and some other fibers.ConclusionThe results of the present study indicated that patients with treatment-naive adult ADHD showed disrupted structural connectivity, which contributes to less efficient information transfer in the ADHD brain and pathophysiology of ADHD.Trial registrationUMIN Clinical Trials Registry (UMIN-CTR) UMIN000025183, Registered: 5 January 2017.

Abstract
Periodontal disease is caused by dysbiosis of the dental biofilm and the host inflammatory response. Various pathogenic factors, such as proteases and lipopolysaccharides (LPSs) produced by bacteria, are involved in disease progression. Endotoxin tolerance is a function of myeloid cells, which sustain inflammation and promote tissue regeneration upon prolonged stimulation by endotoxins such as LPS. The role of endotoxin tolerance is gaining attention in various chronic inflammatory diseases, but its role in periodontal disease remains elusive. Oxidative stress, one of the major risk factors for periodontal disease, promotes disease progression through various mechanisms, of which only some are known. The effect of oxidative stress on endotoxin tolerance has not yet been studied, and we postulated that endotoxin tolerance regulation may be an additional mechanism through which oxidative stress influences periodontal disease. This study aimed to reveal the effect of oxidative stress on endotoxin tolerance and that of endotoxin tolerance on periodontitis progression. The effect of oxidative stress on endotoxin tolerance was analyzed in vitro using peritoneal macrophages of mice and hydrogen peroxide (H2O2). The results showed that oxidative stress inhibits endotoxin tolerance induced by Porphyromonas gingivalis LPS in macrophages, at least partially, by downregulating LPS-elicited negative regulators of Toll-like receptor (TLR) signaling. A novel oxidative stress mouse model was established using SMP30KO mice incapable of ascorbate biosynthesis. Using this model, we revealed that oxidative stress impairs endotoxin tolerance potential in macrophages in vivo. Furthermore, gingival expression of endotoxin tolerance-related genes and TLR signaling negative regulators was decreased, and symptoms of ligature-induced periodontitis were aggravated in the oxidative stress mouse model. Our findings suggest that oxidative stress may contribute to periodontitis progression through endotoxin tolerance inhibition.

Abstract
PURPOSE This study aimed to compare the short- and long-term outcomes of laparoscopic D3 lymph node (LN) dissection between ligation of the inferior mesenteric artery (IMA) (LIMA) and preservation of the IMA (PIMA) for descending colon cancer using propensity score-matched analysis. METHODS This retrospective study included 101 patients with stage I-III descending colon cancer who underwent laparoscopic D3 LN dissection with LIMA (n = 60) or PIMA (n = 41) at a single center between January 2005 and March 2022. After propensity score matching, 64 patients (LIMA, n = 32; PIMA, n = 32) were included in the analysis. The primary endpoint was the long-term outcomes, and the secondary endpoint was the surgical outcomes. RESULTS In the matched cohort, no significant difference was noted in the surgical outcomes, including the operative time, estimated blood loss, number of harvested LNs, number of harvested LN 253, and complication rate. The long-term outcomes were also not significantly different between the LIMA and PIMA groups (3-year recurrence-free survival, 72.2% vs. 75.6%, P = 0.862; 5-year overall survival, 69.8% vs. 63.4%, P = 0.888; 5-year cancer-specific survival, 84.2% vs. 82.8%, P = 0.607). No recurrence of LN metastasis was observed around the IMA root. CONCLUSION Laparoscopic D3 dissection in PIMA was comparable to that in LIMA regarding both short- and long-term outcomes. The optimal LN dissection for descending colon cancer should be investigated in future large-scale studies.

Abstract
Introduction External Quality Assessment (EQA) schemes are designed to provide a snapshot of laboratory proficiency, identifying issues and providing feedback to improve laboratory performance and inter-laboratory agreement in testing. Currently there are no international EQA schemes for seasonal influenza serology testing. Here we present a feasibility study for conducting an EQA scheme for influenza serology methods. Methods We invited participant laboratories from industry, contract research organizations (CROs), academia and public health institutions who regularly conduct hemagglutination inhibition (HAI) and microneutralization (MN) assays and have an interest in serology standardization. In total 16 laboratories returned data including 19 data sets for HAI assays and 9 data sets for MN assays. Results Within run analysis demonstrated good laboratory performance for HAI, with intrinsically higher levels of intra-assay variation for MN assays. Between run analysis showed laboratory and strain specific issues, particularly with B strains for HAI, whilst MN testing was consistently good across labs and strains. Inter-laboratory variability was higher for MN assays than HAI, however both assays showed a significant reduction in inter-laboratory variation when a human sera pool is used as a standard for normalization. Discussion This study has received positive feedback from participants, highlighting the benefit such an EQA scheme would have on improving laboratory performance, reducing inter laboratory variation and raising awareness of both harmonized protocol use and the benefit of biological standards for seasonal influenza serology testing.

Abstract
BACKGROUND Nonadherence among pediatric transplant recipients is a significant problem that reduces graft survival and leads to poor kidney graft outcomes. It is, however, extremely difficult to detect during a regular follow-up. This study, therefore, aimed to investigate the risk factors involved in nonadherence, focusing on unexplained transient hyperuricemia in pediatric kidney transplant (KTx) recipients at a single pediatric center. METHODS This retrospective study included 167 patients who underwent KTx at our pediatric center. A Cox proportional hazards analysis was performed to evaluate the risk of nonadherence using the following factors: age, sex, body mass index SD score, transient hyperuricemia, hypertension, and follow-up period. RESULTS Nonadherence was identified in 19 patients (11%), with the average (SD) age and post-KTx duration at diagnosis being 17.21 (4.73) years and 79.21 (38.77) months, respectively. Thirty-four patients (20%) were diagnosed with transient hyperuricemia at a median of 14 months after KTx. On multivariate Cox regression analysis, transient hyperuricemia was the only independent risk factor for nonadherence after KTx. CONCLUSIONS Transient hyperuricemia was identified as one of the risk factors for nonadherence after KTx; therefore, careful monitoring for transient hyperuricemia may allow early detection of nonadherence.

Abstract
OBJECTIVES Few studies have compared the tumor-site-based postoperative short-term outcomes of a bridge to surgery using self-expandable metallic stents. This study compared the perioperative outcomes following stent placement between right- and left-sided obstructive colorectal cancers, focusing on patients undergoing laparoscopic surgery. METHODS This study included 127 patients with stage I-IV obstructive colorectal cancer (right-sided, n = 25 [19.7%]; left-sided, n = 102 [80.3%]) who underwent laparoscopic-assisted surgery following stent placement between May 2012 and September 2021. We compared the postoperative complication rates and the success rates of stent placement. RESULTS The clinical success rate was not significantly different (92% vs. 97.1%, P = 0.254). The rates of all-grade complications (36% vs. 16.7%, P = 0.05) and postoperative ileus or small-bowel obstruction (20% vs. 2%, P = 0.003) were significantly higher in the right-sided group. The rates of the Clavien-Dindo classification ≥ III complications (8% vs. 6.9%, P = 1) and the median durations of postoperative hospital stay (8 days vs. 8 days, P = 1) were not significantly different. On multivariate analysis, right-sided colon cancer was an independent risk factor for postoperative ileus or small-bowel obstruction (odds ratio [OR]: 16.5, 95% confidence interval [CI]: 2.42-112, P = 0.004) but not for all grades of complications (OR: 2.63, 95% CI: 0.976-7.09, P = 0.056). CONCLUSIONS Although the rates of clinical success, postoperative Clavien-Dindo classification ≥ III severe complications, and postoperative hospital stay were comparable, the bridge to surgery following stent placement for right-sided obstructive colon cancer raises concerns about ileus or small-bowel obstruction.

Abstract
A 66-year-old man underwent laparoscopic low anterior resection for rectal cancer. A transanal decompression tube (24Fr Nelaton catheter) was placed laparoscopically during the surgery. Contrast enema on postoperative day 5 showed perforation of the sigmoid colon around the tip of the tube, and emergency laparotomy was performed. Perforation of the posterior sigmoid colon located on the proximal side of the colorectal anastomosis at the level of the promontorium was identified. Closure of the perforation site, lavage drainage, and a diverting loop ileostomy were performed. Although a transanal decompression tube is useful in preventing anastomotic leakage, tube-related colon perforation should be noted, and controversies about the safety of laparoscopically transanal decompression tube placement should be resolved. Adequate management for tube placement should be discussed.

Abstract
AIM There is a concern that the differential diagnosis of a groin mass depends on a physicians' subjective judgment and experience. We aimed to clarify the significance of US in the diagnosis of a groin mass. MATERIAL AND METHODS This retrospective study included 1,898 patients who underwent US examination of a groin mass. Physicians' diagnoses were compared with US-based diagnoses. Furthermore, the incidence of asymptomatic contralateral hernia was analyzed. The frequency of unnecessary surgery in patients with and without preoperative US was compared. In 1,451 patients who underwent surgery with preoperative US, the preoperative US classification was compared with surgical diagnosis. RESULTS Of 1,805 patients diagnosed with an inguinal hernia by physicians, 190 (10.5%) exhibited no US findings of inguinal hernia. US revealed asymptomatic contralateral hernia in 13.3% of the 1,543 patients in whom a physician detected unilateral inguinal hernia. The frequency of unnecessary surgery was significantly associated with preoperative US (1/1451; 0% vs. 2/351, 0.6%; p=0.0382). The overall US diagnostic accuracy for the inguinal hernia type was 92.7%. CONCLUSIONS US imaging of a groin mass can help avoid unnecessary surgery, detect latent inguinal hernia, and guide surgical planning.

Abstract
We herein report two patients with hepatocellular carcinoma (HCC) who exhibited intraabdominal bleeding caused by tumor rupture soon after lenvatinib initiation. A hypervascular nodule was present in the lateral segment manifesting extrahepatic protrusion in an 81-year-old-man and in the caudate lobe, which was completely occupied by the tumor, in an 83-year-old-man. Both patients were given lenvatinib, and epigastralgia occurred suddenly three and five days later. Computed tomography revealed high-attenuation areas suggesting bleeding around the left and caudate lobes. Considering the strong antiangiogenic effects by lenvatinib, transcatheter arterial embolization should be performed before lenvatinib initiation in patients with subcapsular HCC.

Abstract
BACKGROUND/AIM To compare the outcomes of totally implantable central venous access device (TIVAD) insertions by surgical residents (SRs) with those by experienced surgeons (ESs) and establish the safety of percutaneous TIVAD insertion by SRs. PATIENTS AND METHODS A total of 700 insertions were successfully performed between January 2015 and December 2019 in our Department. The puncture site conversion and complication rates were compared, and risk factors related to complications were analysed. RESULTS In total, 84 and 616 insertions were performed in the SR and ES groups, respectively. SRs mainly punctured the internal jugular vein (IJV), and ESs punctured the subclavian vein (SV). The conversion rate from the IJV to SV was similar, whereas that from the SV to IJV was higher by SRs than ESs. Overall, early, and delayed complications were similar between the two groups. CONCLUSION Percutaneous TIVAD inserted into the IJV by an SR was demonstrated to be safe.

Abstract
Background The activation of melanocortin 1 receptor (MC1R) on melanocytes stimulates the production of eumelanin. A tridecapeptide α melanocyte‐stimulating hormone (αMSH) is known to induce skin pigmentation. Objectives We characterised the properties of a novel oral MC1R agonist dersimelagon (MT‐7117) with respect to its specific binding to MC1R, downstream signalling and eumelanin production in experimental models. Methods The competitive binding and production of intracellular cyclic adenosine 3′, 5′‐monophosphate in cells expressing recombinant melanocortin receptors were examined. A mouse melanoma cell line B16F1 was used for the evaluation of in vitro melanin production. The in vitro activity of MT‐7117 was determined with αMSH and [Nle4, D‐Phe7]‐αMSH (NDP‐αMSH) as reference comparators. The change of coat colour and skin pigmentation were evaluated after repeat administration of MT‐7117 by oral gavage to C57BL/6J‐Ay/+ mice and cynomolgus monkeys, respectively. Results MT‐7117 showed the highest affinity for human MC1R compared to the other melanocortin receptors evaluated and agonistic activity for human, cynomolgus monkey and mouse MC1R, with EC50 values in the nanomolar range. In B16F1 cells, MT‐7117 increased melanin production in a concentration‐dependent manner. In vivo, MT‐7117 (≥0.3 mg/kg/day p.o.) significantly induced coat colour darkening in mice. MT‐7117 (≥1 mg/kg/day p.o.) induced significant skin pigmentation in monkeys and complete reversibility was observed after cessation of its administration. Conclusions MT‐7117 is a novel oral MC1R agonist that induces melanogenesis in vitro and in vivo, suggesting its potential application for the prevention of phototoxic reactions in patients with photodermatoses, such as erythropoietic protoporphyria and X‐linked protoporphyria.

Abstract
PURPOSE To the best of our knowledge, no studies have compared the short-term outcomes between colo-colonic extracorporeal triangular anastomosis (TA) and functional end-to-end anastomosis (FEEA), with a focus on laparoscopic-assisted surgery for left-sided colon cancer. Therefore, this study compared the short-term outcomes of these anastomoses using propensity score matching analysis. METHODS This retrospective study included 129 patients with stage I-IV left-sided colon cancer who underwent laparoscopic-assisted surgery with colo-colonic extracorporeal TA (n = 75) or FEEA (n = 54) between May 2009 and March 2021. After propensity score matching, 84 patients (TA, n = 42; FEEA, n = 42) were included in the analysis. The primary endpoint was the complication rate for all grades, and the secondary endpoints were the rates of Clavien - Dindo grade ≥ 3 complications and anastomotic leakage. RESULTS In the matched cohort, there were no significant differences in the complication rates for all grades (35.7% vs. 26.2%, p = 0.479), Clavien - Dindo grade ≥ 3 complications (11.9% vs. 11.9%, p = 1), and anastomotic leakage (0% vs. 4.8%, p = 0.494) between the TA and FEEA groups. In the univariate logistic regression analysis, TA did not increase the frequency of complications for any grades compared with FEEA (odds ratio: 1.570, 95% confidence interval: 0.616-3.980, p = 0.347). CONCLUSION Extracorporeal TA demonstrated equivalent short-term outcomes compared with FEEA in cases of laparoscopic-assisted surgery for left-sided colon cancer. TA can be an alternative anastomosis technique in cases wherein FEEA is difficult to perform.

Abstract
INTRODUCTION Laparoscopic Hartmann's reversal (LHR) has recently been reported to be safer and more feasible than open Hartmann's reversal (OHR); however, there is limited data on the outcomes of LHR compared with those of OHR from Asian countries. Therefore, we aimed to clarify the postoperative outcomes of LHR compared with OHR, and additionally compare the patient outcomes post-LHR according to the previous Hartmann's procedure (HP) approach. METHODS Patients who underwent OHR and LHR between January 2006 and September 2020 in a single center in Japan, were retrospectively evaluated. Patient characteristics and perioperative data were collected from the medical and surgical records and assessed. RESULTS Overall, 15 and 19 patients underwent OHR and LHR, respectively, between January 2006 and September 2020. LHR was associated with less blood loss (median: 15 mL vs 185 mL; P < .001) and shorter hospital stays (9 days vs 14 days; P = .023) than OHR. There was no significant difference in postoperative complications between LHR and OHR (26.3% vs 40.0%, P = .475). However, two severe anastomotic complications in LHR were observed in patients with the stump below the peritoneal reflection. No significant difference in outcomes was observed between LHR patients who underwent open and laparoscopic HP. CONCLUSION LHR resulted in positive outcomes regarding estimated blood loss and postoperative hospitalization, compared with OHR. Although the postoperative complications between LHR and OHR were not significant, patients with the stump below the peritoneal reflection may be at a high risk of anastomotic complications.

Abstract
Background: Cellulitis is frequently encountered in patients with lymphedema despite existing prevention protocols. To resolve this issue, social aspects surrounding patients, such as communication with patients and professionals, are necessary to consider new approaches. This study aimed to clarify the association between the history of cellulitis in patients with lymphedema and access to specialists after adjustment for relevant confounding factors. Methods and Results: This study was a secondary analysis of the Lymphoedema IMpact and PRevalence-INTernational (LIMPRINT) study using a national Japanese database of adult lymphedema compiled between 2014 and 2015 (n = 113). Descriptive data were collected for patient characteristics. Multivariate logistic regression analysis was conducted to explore possible risk factors for patients having experienced cellulitis. The duration of edema ranged from <6 months (16.2%) to 10 years or longer (25.2%), with varying severity. History of cellulitis was observed in 31.9% of patients. The prevalent treatment techniques within the context of complex decongestive therapy included skin care advice (52.2%), compression garments (55.8%), exercise advice (41.6%), multilayer bandages (38.1%), cellulitis advice (49.6%), and massage (61.1%). Overall, 57.1% of patients had access to lymphedema specialists. Longer duration of lymphedema (adjusted odds ratio [AOR] = 4.10, p = 0.005) and access to lymphedema specialists (AOR = 0.28, p = 0.009) were significantly associated with a history of cellulitis. Conclusions: A history of cellulitis in patients with lymphedema is associated with limited access to specialists. To support self-care in this patient population, reasonable consideration systems, including telehealth, should be developed to facilitate communication between specialists and patients and decrease the occurrence of cellulitis in lymphedema.

Abstract
PURPOSE Few studies have investigated the long-term oncological outcomes of the self-expandable metallic stent (SEMS) as a bridge to surgery (BTS) for obstructive colorectal cancer (OCRC). We conducted this study to compare the short- and long-term outcomes of the SEMS with those of the traditional transanal decompression tube (TDT) in patients with stage II and III left-sided OCRC. METHODS The subjects of this retrospective study were 78 patients with pathological stage II and III left-sided OCRC who underwent radical surgery after SEMS or TDT placement, between April, 2005 and September, 2019. We compared perioperative data, including decompression success rates and 3-year relapse-free survival (RFS), between the SEMS and TDT groups. RESULTS A SEMS was placed in 60 (76.9%) patients and a TDT was placed in 18 (23.1%) patients, achieving a clinical success rate of decompression of 98.3% in the SEMS group and 77.8% in the TDT group (P = 0.009). The 3-year RFS of the overall cohort was better in the SEMS group than in the TDT group (74.9% vs. 40.9%, respectively; P = 0.003). CONCLUSIONS Decompression using a SEMS as the BTS may improve oncological outcomes over those achieved by a TDT in patients with left-sided stage II and III OCRC.

BACKGROUND The prognostic value of positive intraoperative peritoneal cytology and lavage cytology, including the differences in their prognostic impact, in colorectal cancer is controversial. We aimed to investigate the prognostic values of positive peritoneal cytology and lavage cytology findings for colorectal cancer and compare their prognostic impact. METHODS We retrospectively evaluated 592 clinical stage II-IV colorectal cancer patients who underwent peritoneal cytology (n = 225) or lavage cytology (n = 367) between November 1993 and December 2018. The prognostic factors for cancer-specific survival were identified, and the differences in cancer-specific survival were examined between the patients. RESULTS The cytology-positive rate was 10.8% (64/592), 17.8% (40/225), and 6.5% (24/367) in the overall, peritoneal cytology, and lavage cytology groups, respectively. Both positive peritoneal cytology (hazard ratio: 2.196) and lavage cytology (hazard ratio: 2.319) were independent prognostic factors. The peritoneal cytology-positive group showed significantly poorer cancer-specific survival than the cytology-negative group (5-year: 3.5% vs. 59.5%; 10-year: 3.5% vs. 46.1%, p < 0.001). Similar results were obtained for lavage cytology (5-year: 14.1% vs. 73.9%; 10-year: 4.7% vs. 63.5%, p < 0.001). The cancer-specific survival was not significantly different between the peritoneal cytology-positive and lavage cytology-positive groups (p = 0.058). Both positive peritoneal and lavage cytology were associated with poorer cancer-specific survival across all colorectal cancer stages. CONCLUSIONS Positive peritoneal and lavage cytology are associated with worse cancer-specific survival in colorectal cancer. The prognostic impact was comparable between positive lavage and peritoneal cytology. Thus, cytology should be a standard assessment modality for colorectal cancer.

Abstract
OBJECTIVE Sesamin is a functional ingredient in sesame (Sesamum indicum) seeds and has many physiological effects. This study investigated whether sesame lignans, sesamin and episesamin (1:1), can suppress age-related disorders of the kidney. MATERIALS AND METHODS Twenty-month-old mice were divided into three groups, and each group received a regular diet (O-C), diet containing sesame lignans (O-SE), and diet containing sesame lignans and α-tocopherol (VE; O-SE+VE), respectively, for 5 months. Six-month-old young mice (Y-C) were compared to the older mice. RESULTS Renal lipofuscin deposition was increased in the O-C group compared to that in the Y-C group and its deposition with aging was significantly decreased in both O-SE and O-SE+VE groups. Plasma blood urea nitrogen levels in the O-C group increased compared to those in the Y-C group; however, those in both O-SE and O-SE+VE groups did not differ from those in the Y-C group. The number of podocytes in the O-C group decreased compared to that in the Y-C group and this effect was attenuated in the O-SE and O-SE+VE groups. The effect was strongest in the O-SE+VE group. Histological examinations showed that glomerular hypertrophy accompanied by mesangial hyperplasia and renal tubular degeneration was less severe in the O-SE and O-SE+VE groups than in the O-C group. Moreover, age-related increases in the mRNA expression of NADPH oxidase- and inflammation-related genes, including p67phox, p40phox, TNFα, and IL-6, in the kidney were suppressed in the O-SE and O-SE+VE groups. CONCLUSIONS Sesame lignans might be useful to suppress age-related kidney disorders, and these effects could be enhanced with VE.

Abstract
Background Energy inadequacy has a great impact on health outcomes in older adult patients; however, it is difficult to evaluate energy adequacy in these patients, especially in home-care settings. We recently reported that temporal muscle thickness can be an indicator of nutritional status. The present study aims to examine whether a change in temporal muscle thickness is directly correlated with energy adequacy and, if so, to determine the cutoff value of a change in temporal muscle thickness to detect energy inadequacy. Methods A prospective cohort study was conducted from September 2015 to June 2016 in two hospitals in Japan, and included bedridden older adult patients aged ≥65 years. Temporal muscle thickness was measured using ultrasonography. Energy intake was estimated by photographic diet records. Total energy expenditure (TEE) was estimated by multiplying basal energy expenditure calculated using the Harris– Benedict equation by activity and stress factors. Energy adequacy was then calculated by dividing TEE by energy intake. Pearson’s correlation coefficient was used to examine the relationship between percentage change in temporal muscle thickness and energy adequacy. Multiple logistic regression analysis was conducted to determine the direct relationship between percentage change in temporal muscle thickness and moderate energy inadequacy (energy adequacy< 75%). Receiver operating characteristic (ROC) analysis was performed to determine the cutoff point for percentage change in temporal muscle thickness to detect moderate energy inadequacy. Results Forty-eight patients were analyzed (mean age 84.4 ± 7.8 years; 54.2% were women). The percentage change in muscle thickness was significantly correlated with energy adequacy (r = 0.733, p < 0.001). ROC analysis identified a percentage change in temporal muscle thickness of − 3.6% as the optimal cutoff point for detecting moderate energy inadequacy. Percentage change in muscle thickness was independently correlated with energy inadequacy after adjusting for age, sex, and masticatory status (AOR 0.281, 95% CI 0.125–0.635). Conclusions Changes in temporal muscle thickness are directly correlated with energy adequacy and can indicate moderate energy inadequacy in bedridden older adults. These results suggest the assessment of changes in temporal muscle thickness could be useful for guiding nutritional care in older adult patients in home-care settings.

Abstract
Abstract
Background
Recent Cochrane Systematic Review suggested that the participation in cardiac rehabilitation is associated with approximately 20% lower cardiovascular mortality and morbidity. Exercise therapy is the key component of cardiac rehabilitation programs. In recent years, innovative technologies have been introduced into the field of rehabilitation, and a typical example is the wearable cyborg Hybrid Assistive Limb (HAL). The wearable cyborg HAL provides motion assistance based on detection of bioelectrical signals on the skin surface when muscle forces are generated. The lumbar-type HAL is expected to expand the therapeutic options for severe cardiac patients who have difficulty in performing usual cardiac rehabilitation programs, such as bicycle pedaling or walking.
Purpose
We aim to compare the efficacy of exercise therapy performed with motion assistance from a lumbar-type HAL versus conventional training (sit-to-stand exercise without HAL) in patients with chronic heart failure.
Methods
This clinical trial is a randomized, non-blinded, and controlled study. Twenty-eight heart failure patients (73.1±13.8 years) who have difficulty in walking at the usual walking speed of healthy subjects were randomly assigned to 2 groups (HAL group or control group) with a 1:1 allocation ratio and performed sit-to stand exercise either with HAL or without HAL for 5 to 30 minutes once a day, and 6 to 10 days during the study period. The brain natriuretic peptide (BNP), isometric knee extensor strength, standing ability (30-seconds chair-stand test: CS-30), short physical performance battery (SPPB) and 6-minute walking distance (6MWD) were measured before and after the completion of cardiac rehabilitation. Cardiac events such as death, re-hospitalization, myocardial infarction and worsening of angina pectoris and heart failure during 1 year after discharge were evaluated.
Results
There was no significant difference in the number of days of exercise therapy between the two groups. BNP, SPPB and 6MWD were improved in both groups. In the HAL group, the isometric knee extensor strength (0.29±0.11 vs 0.35±0.11 kgf/kg, p=0.003) significantly improved and CS-30 (5.5±5.1 vs 8.2±5.3, p=0.054) tended to improve. However, in the control group, either the isometric knee extensor strength (0.35±0.11 vs 0.36±0.14 kgf/kg, p=0.424) or CS-30 (6.0±4.3 vs 9.2±6.2, p=0.075) did not significantly change. HAL group showed significantly more improvement in the isometric knee extensor strength than control group (p=0.045). Cardiac events occurred in 20% in the HAL group and 43% in the control group.
Conclusion
The improvement in isometric knee extensor strength with the assistance from lumbar-type HAL suggests that exercise therapy using this device may be useful in chronic heart failure patients with flail or sarcopenia, a strong poor prognostic factor in these patients.

Abstract
Abstract
Background
Percutaneous coronary intervention (PCI) is often complicated by periprocedural myocardial injury (PMI) manifested by elevated cardiac biomarkers. The occurrence of PMI has been shown to be associated with worse clinical outcome over short- and long-term.
Purpose
We performed multidetector computed tomography (MDCT) and cardiac magnetic resonance imaging (CMR) to evaluate the relationship between culprit plaque characteristics and PMI.
Methods
A total of 90 patients who underwent elective PCI were underwent CMR and multidetector coronary tomography before PCI. The high intensity plaque (HIP) on CMR was defined as a coronary plaque to myocardium signal intensity ratio (PMR) of >1.4. The plaque characteristics and the presence of napkin-ring sign (NRS) were analyzed on MDCT. PMI was defined as an increase in cardiac Troponin T levels to more than 5 times the upper limit of normal at 24 h after PCI. Patients were divided into 2 groups according to the presence (Group I, n=26) or absence (Group II, n=64) of PMI.
Results
Spotty calcification, positive remodeling, low attenuation plaque and NRS on MDCT were significantly more observed in Group I than in Group II. HIP on CMR was significantly more observed in Group I than in Group II. In the multivariable logistic regression analysis, the presence of NRS and HIP were significantly independent predictors of PMI (odds ratio (OR) 4.82, 95% confidence interval 1.13–20.60, P=0.034 and OR 3.66, 95% CI 1.09–12.30, P=0.036, respectively). Moreover, for prediction of PMI, NRS and HIP showed a high positive predictive value of 81%, and their absence showed a high negative predictive value of 91%.
Conclusions
MDCT and CMR may play an important role in detecting which lesions are high risks for myocardial necrosis after PCI in elective coronary stenting.

Abstract
Abstract
Background
Although elevated oxidized low-density lipoprotein could play critical roles in vulnerable plaque, there are no studies that compared coronary high-intensity plaque (HIP) on non-contrast T1-weighted magnetic resonance imaging (T1WI_MRI) and circulating malondialdehyde-modified low-density lipoprotein (MDA-LDL) levels for the prediction of cardiac events.
Methods and results
A total of 139 patients with coronary artery stenosis (>70%) were examined with non-contrast T1WI using a 1.5-T MRI (HIP: n=63, non-HIP: n=76). Scheduled percutaneous coronary intervention (PCI) for culprit lesions was performed within 48 h after MRI. HIP was defined as a signal intensity of coronary plaque to cardiac muscle ratio (PMR) of ≥1.4. At admission, circulating levels of MDA-LDL and other lipid-related markers were measured. We evaluated the subsequent cardiac events, which were defined as major adverse cardiac events (MACE; cardiac death, myocardial infarction, and/or ischemia-driven PCI) during follow-up periods (5.6±1.3 years). Circulating MDA-LDL levels were significantly higher in patients with HIP than in those without HIP (p<0.0001). MDA-LDL levels were significantly correlated with PMR (r=0.490, p<0.0001). In multivariable logistic regression analysis, MDA-LDL levels were independently associated with the presence of HIP (OR 1.05; 95% CI, 1.02–1.08, p<0.0001). The incidence of MACE was significantly higher in patients with HIP (27%) than in those without HIP (5%; p=0.011 by the log-rank test). In the multivariable Cox proportional hazard analysis, the MDA-LDL levels (HR 1.03; 95% CI:1.01–1.05, p=0.007) and PMR (HR 2.39; 95% CI:1.19–4.65, p=0.016) were significantly associated with MACE. For MACE prediction, the C-statistic values for MDA-LDL, PMR, and PMR+MDA-LDL were 0.724, 0.791, and 0.800, respectively. Compared with MDA-LDL alone, the addition of PMR to MDA-LDL increased the net reclassification improvement by 0.78 (p=0.012).
Conclusions
MDA-LDL levels might be associated with the presence of HIP in patients with coronary artery disease. Furthermore, adding PMR to MDA-LDL levels markedly improved MACE prediction.

Abstract
Abstract
Background/Introduction Pulmonary vein isolation (PVI) is a cornerstone of curable treatment for atrial fibrillation (AF). Left ventricular (LV) ejection fraction (EF) occasionally improves after PVI in AF patients with reduced LVEF (rEF), the mechanism of which is not fully understood. CASTLE-AF trial have demonstrated that PVI with radiofrequency (RF) catheter for AF patients with rEF can reduce their mortality and heart failure. Nevertheless there are limited data about the clinical outcome of the PVI for patients with impaired LV function.
Purpose
This study was to evaluate the efficacy of PVI and improvement of LVEF after the procedure in AF patients with rEF.
Methods
A total of 2709 consecutive AF patients (age 65±39 y/o, male 67%) underwent their first PVI with cryoballoon or RF catheter in our facility from April 2014 to March 2019, and retrospectively analyzed. All the patients underwent echocardiogram before and half to one year after the procedure. Patients with LVEF under 40% before the PVI were selected (n=111) and divided into two groups based on whether there were specific etiologies of LV function impairment (group A) or not (group B).
Results
There were no significant difference in mean LVEF between group A (n=40) and group B (n=71) (32±6% vs 33±6%, p=0.12). The major etiology of rEF in group A were old myocardial infarction (n=20, 18%), hypertensive heart disease (n=6, 5.4%), and dilated cardiomyopathy (n=5, 4.5%). After mean follow-up of 2.7 years, there were no significant difference in clinical outcome after the procedure between two groups (1-year Kaplan–Meier event rate estimates; 72.2% vs 72.9%; p=0.85). The change amounts of LVEF after the PVI were significantly higher in group B (20±14%) compared to group A (2±10%) (p<0.001). Multivariable Cox regression analysis revealed that age was the independent significant predictors of EF improvement over 10% in group B (p=0.048).
Conclusions
In AF patients with reduced LVEF, there were no significant difference in efficacy of PVI between those who have specific etiologies of LV function impairment other than AF and who have not. The improvement of LVEF after PVI was significantly larger in patients without specific etiologies compared to those with.

Abstract
Sleep behaviors are observed even in nematodes and arthropods, yet little is known about how sleep-regulatory mechanisms have emerged during evolution. Here, we report a sleep-like state in the cnidarian Hydra vulgaris with a primitive nervous organization. Hydra sleep was shaped by homeostasis and necessary for cell proliferation, but it lacked free-running circadian rhythms. Instead, we detected 4-hour rhythms that might be generated by ultradian oscillators underlying Hydra sleep. Microarray analysis in sleep-deprived Hydra revealed sleep-dependent expression of 212 genes, including cGMP-dependent protein kinase 1 (PRKG1) and ornithine aminotransferase. Sleep-promoting effects of melatonin, GABA, and PRKG1 were conserved in Hydra However, arousing dopamine unexpectedly induced Hydra sleep. Opposing effects of ornithine metabolism on sleep were also evident between Hydra and Drosophila, suggesting the evolutionary switch of their sleep-regulatory functions. Thus, sleep-relevant physiology and sleep-regulatory components may have already been acquired at molecular levels in a brain-less metazoan phylum and reprogrammed accordingly.

Abstract
The cardiac plexus, which contains parasympathetic ganglia, plays an important role in regulating cardiac function. Histamine is known to excite intracardiac ganglion neurons, but the underlying mechanism is obscure. In the present study, therefore, the effect of histamine on rat intracardiac ganglion neurons was investigated using perforated patch-clamp recordings. Histamine depolarized acutely isolated neurons with a half-maximal effective concentration of 4.5 μM. This depolarization was markedly inhibited by the H1 receptor antagonist triprolidine and mimicked by the H1 receptor agonist 2-pyridylethylamine, thus implicating histamine H1 receptors. Consistently, reverse transcription-PCR (RT-PCR) and Western blot analyses confirmed H1 receptor expression in the intracardiac ganglia. Under voltage-clamp conditions, histamine evoked an inward current that was potentiated by extracellular Ca2+ removal and attenuated by extracellular Na+ replacement with N-methyl-D-glucamine. This implicated the involvement of non-selective cation channels, which given the link between H1 receptors and Gq/11-protein-phospholipase C signalling, were suspected to be transient receptor potential canonical (TRPC) channels. This was confirmed by the marked inhibition of the inward current through the pharmacological disruption of either Gq/11 signalling or intracellular Ca2+ release and by the application of the TRPC blockers Pyr3, Gd3+ and ML204. Consistently, RT-PCR analysis revealed the expression of several TRPC subtypes in the intracardiac ganglia. Whilst histamine was also separately found to inhibit the M-current, the histamine-induced depolarization was only significantly inhibited by the TRPC blockers Gd3+ and ML204, and not by the M-current blocker XE991. These results suggest that TRPC channels serve as the predominant mediator of neuronal excitation by histamine.

Abstract
Neope goschkevitschii and Lethe sicelis are endemic Satyrinae butterflies in mainland Japan, which belongs to the Palearctic realm. In this study, we determined the mitochondrial genomes of these two species. The total length of the mitochondrial genome was 15,286 bp and 15,196 bp for N. goschkevitschii and L. sicelis, respectively, and both mitochondrial genomes were extremely AT-rich. Phylogenetic analysis revealed each of these species was closely related to a member of the same genus, respectively.

Abstract
OBJECTIVE The purpose of this study was to segregate the genetic lines responsible for the orange area of coloration in males and the response to orange coloration exhibited by females in the guppy (Poecilia reticulata) through artificial selection. This study is part of a project that uses QTL-seq to search for candidate genes involved in male orange coloration and female response to male coloration. We created two lines: high-selected lines of males having large areas of orange spots and of females with high response to male orange coloration; and low-selected lines of males having small areas of orange spots and of females with low response to male orange coloration. RESULTS The male orange area and the female response became significantly different between high- and low-selected lines after three generations of artificial selection. This indicates that the differences in the frequencies of alleles at loci affecting the orange area and the female response between the lines increased over the generations through selection.

Abstract
Background: This was a part of LIMPRINT (Lymphoedema IMpact and PRevalence—INTernational), an international study aimed at capturing the size and impact of lymphedema and chronic edema in different countries and health services across the world. The purpose of this study was to clarify the prevalence and the impact of chronic edema in Japan. Methods and Results: This was a two-phase facility-based study to determine the prevalence and functional impact of chronic edema in the adult population in Japan between 2014 and 2015. The prevalence study involved a university hospital, an acute community hospital, and a long-term medical facility. The impact study involved six facilities, including two outpatient clinics in acute care hospitals (one led by a physician and the other led by a nurse), inpatient wards in two acute care hospitals, and two nursing home/long-term care facilities. Various questionnaires and clinical assessments were used to gather patient demographic data and assess the functional impact of chronic edema. The results showed that chronic edema was much more prevalent in the long-term care facility than in acute care hospitals; cellulitis episodes occurred in ∼50% of cases in the gynecologist-led outpatient clinic, even though >80.0% of patients received standard management for edema; edema was found in the trunk region, including the buttock, abdomen, and chest-breast areas, in addition to the upper and lower limbs; and subjective satisfaction with edema control was low, even though the quality-of-life scores were good. Conclusions: The prevalence of chronic edema varied according to the facility type, ranging from 5.0% to 66.1%. The edema was located in all body parts, including the trunk region. Subjective satisfaction with control of edema was poor, while general quality of life was good. This large health care issue needs more attention.
