Abstract
We present a novel system, a liquid-state pillar[5]arene decorated with tri(ethylene oxide) chains, that brings electron-donor and electron-acceptor molecules into proximity for efficient exciplex formation. The electron-accepting guests exhibit a blue-purple emission from a localized excited state upon excitation in common solvents. However, directly dissolving the guests in the electron-donating pillar[5]arene liquid (a bulk system) results in visible green emission from the formed exciplexes. In the bulk system, the guest molecules are always surrounded by excess pillar[5]arene molecules, resulting in the formation of mainly inclusion-type exciplexes. In the bulk system, energy migration occurs between the pillar[5]arene molecules. Excitation of the pillar[5]arenes results in a more intense green exciplex emission than that observed upon direct excitation of the guests. In summary, the pillar[5]arene liquid is a novel system for achieving efficient exciplex formation and energy migration that is different from typical solvent and solid systems.

Abstract
Epithelial-mesenchymal transition (EMT) is a crucial mechanism that facilitates cancer cell metastasis. Despite its importance, the clinical significance of EMT in gastric cancer (GC) patients has yet to be clearly demonstrated. For gauging the extent of EMT in GC, we employed gene set variation analysis to score 807 patient samples from two large cohorts: TCGA and GSE84437. In both cohorts, EMT high GC showed a significant association with worse overall survival (hazard ratio (HR) = 1.74, p = 0.011 and HR = 2.01, p < 0.001, respectively). This association was stronger when considering the EMT signature score compared to the individual expressions of EMT-related genes (CDH1, CDH2, VIM, and FN1). While the EMT signature level did not differ among various cancers, high EMT signature specifically correlated with survival in GC alone. Mucinous and diffuse histological types exhibited higher EMT levels compared to others (p < 0.001), and the EMT signature level was correlated with tumor depth and AJCC stage (all p < 0.001). Interestingly, the EMT score was an independent factor for overall and disease-specific survival (multivariate; p = 0.006 and 0.032, respectively). EMT high GC displayed a lower fraction of Th1 cells and a higher fraction of dendritic cells, M1 macrophages and several stromal cells. EMT high GC exhibited an inverse correlation with cell proliferation-related gene sets. While they significantly enriched multiple pro-cancerous gene sets, such as TGF-β signaling, hypoxia, and angiogenesis. The presence of EMT signature in a bulk tumor was linked to TGF-β signaling, hypoxia, and angiogenesis, and was also associated with poorer survival outcomes in GC patients.

Abstract
The recent implementation of attosecond and few-femtosecond X-ray pump/X-ray probe schemes in large-scale free-electron laser facilities has opened the way to visualize fast nuclear dynamics in molecules with unprecedented temporal and spatial resolution. Here, we present the results of theoretical calculations showing how polarization-averaged molecular-frame photoelectron angular distributions (PA-MFPADs) can be used to visualize the dynamics of hydrogen migration in methanol, ethanol, propanol, and isopropyl alcohol dications generated by X-ray irradiation of the corresponding neutral species. We show that changes in the PA-MFPADs with the pump-probe delay as a result of intramolecular photoelectron diffraction carry information on the dynamics of hydrogen migration in real space. Although visualization of this dynamics is more straightforward in the smaller systems, methanol and ethanol, one can still recognize the signature of that motion in propanol and isopropyl alcohol and assign a tentative path to it. A possible pathway for a corresponding experiment requires an angularly resolved detection of photoelectrons in coincidence with molecular fragment ions used to define a molecular frame of reference. Such studies have become, in principle, possible since the first XFELs with sufficiently high repetition rates have emerged. To further support our findings, we provide experimental evidence of H migration in ethanol-OD from ion-ion coincidence measurements performed with synchrotron radiation.

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
BACKGROUND/AIM Ramucirumab plus paclitaxel has been widely used as a second-line chemotherapy for treating advanced gastric cancer. However, the real-world data of this regimen for older patients with gastric cancer (GC) remains unrevealed. The aim of this study was to clarify the feasibility and efficacy of this regimen for older patients with GC in a single-arm, phase II study. PATIENTS AND METHODS Patients aged ≥70 years having unresectable or recurrent GC who met the eligible criteria were enrolled. Paclitaxel was administered at a dose of 80 mg/m2 on days 1, 8, and 15, and ramucirumab was administered at a dose of 8 mg/kg on day 1 and day 15 of a 4-week cycle. Primary endpoint was the incidence of adverse events and secondary endpoints were response rate, progression-free survival, and overall survival. A total of 25 patients were enrolled in the full-set analysis. RESULTS Grade 3 or more adverse events were observed in 21 patients (84.0%). Neutropenia was most frequently observed (68.0%), followed by peripheral sensory neuropathy (12.0%), and febrile neutropenia (12.0%). Median progression-free survival and overall survival were 6.9 months and 13.4 months, respectively. Disease control rate was 88.0%, and response rate of patients with measurable lesions was 52.9%. Notably, no treatment-related deaths occurred. CONCLUSION Ramucirumab plus paclitaxel as a second-line chemotherapy demonstrated acceptable oncological outcomes, despite the occurrence of frequent adverse events. It is necessary to carefully select patients and adjust treatment regimens in older patients with GC to safely administer chemotherapy and subsequently achieve satisfactory long-term outcomes.

Abstract
The aim of this study was to evaluate the anti-allergic potentials of dactolisib, a dual PI3K/mTOR kinase inhibitor, on two important events for allergy: sensitization and the onset of anaphylactic symptoms. After sensitization with the antigen ovalbumin (OVA), five successive oral administrations of dactolisib effectively decreased serum anti-OVA antibody-an indicator of sensitization-levels in mice. In parallel with the antibody levels in their serum, anaphylactic rectal temperature decrease induced by the re-administration of OVA to dactolisib-treated mice was strongly diminished compared to that in vehicle-treated mice. The inhibitor also inhibited ex vivo splenic B cell activation indicated by the increase of phosphorylation of Akt, CD69 expression levels, and proliferation upon anti-B cell receptor antibody treatment, suggesting that suppressive effects of the inhibitor on B cell activation plays a role in its ability to decrease sensitization in vivo. We concurrently observed the anti-anaphylactic ability of dactolisib in vivoand in vitro. A single oral administration of the inhibitor attenuated the anaphylactic rectal temperature decrease induced in a mouse model of passive systemic anaphylaxis. In in vitro mast cell models, pretreatment with the drug inhibited the degranulation response and cytokine production in RBL2H3 cells triggered by IgE and antigens, without affecting cell viability. These results suggest that dactolisib, as well as other PI3K/mTOR inhibitors, might be a good candidate for anti-allergic drugs that exhibit both anti-sensitizing and anti-anaphylactic effects.

Abstract
BACKGROUND/AIM In the previous phase I/II study, we established neoadjuvant chemotherapy (NAC) using bi-weekly docetaxel, cisplatin, and S-1 (DCS) for clinical stage III gastric cancer. This study aimed to clarify long-term outcomes of this treatment. PATIENTS AND METHODS Relapse-free survival (RFS) and overall survival (OS) were calculated by the Kaplan-Meier method and prognostic factors for RFS and OS were identified by univariate analysis. RESULTS A total of 47 patients with clinical stage III gastric cancer were enrolled in this study. The 5-year RFS and OS rates were 69.8% and 74.3%, respectively, in all registered patients. Moreover, the 5-year OS and RFS rates in patients receiving R0 gastrectomy were 68.0% and 79.4%, respectively. Neutrophil-lymphocyte ratio (NLR) before NAC ≥2.41, prognostic nutritional index (PNI) before NAC ≤50.4, Glasgow prognostic score before NAC classification 2, NLR after NAC ≥1.43, PNI after NAC <48.0, and Grade 1a/1b pathological response significantly worsened RFS. NLR after NAC ≥1.43, PNI before NAC ≤50.4, NLR after NAC ≥1.43, and body weight loss >5 kg after NAC significantly worsened OS. CONCLUSION Although bi-weekly DCS therapy as neoadjuvant setting showed acceptable long-term outcomes, poor immune-nutritional status before and after NAC caused worse long-term survival in stage III gastric cancer patients. It is warranted to conduct a well-designed prospective randomized control study to compare long-term outcomes using the bi-weekly DCS regimen between patients with and without immune-nutritional support during peri-NAC.

Abstract
We present a study on molecular-frame photoelectron angular distributions (MFPADs) of small molecules using circularly polarized synchrotron light. We find that the main forward-scattering peaks of the MFPADs are slightly tilted with respect to the molecular axis. This tilt angle is directly connected to the molecular bond length by a simple, universal formula. We apply the derived formula to several examples of MFPADs of C 1s and O 1s photoelectrons of CO, which have been measured experimentally or obtained by means of ab initio modeling. In addition, we discuss the influence of the back-scattering contribution that is superimposed over the analyzed forward-scattering peak in the case of homo-nuclear diatomic molecules such as N2.

Abstract
BACKGROUND AND PURPOSE Arterial stiffness is reported to be able to cause axonal demyelination or degeneration. The present study aimed to use advanced MR imaging techniques to examine the effect of arterial stiffness on the WM microstructure among older adults. MATERIALS AND METHODS Arterial stiffness was measured using the cardio-ankle vascular elasticity index (CAVI). The high-CAVI (mean CAVI ≥ 9 points) and the low-CAVI groups (mean CAVI < 9 points) were created. The neuronal fiber integrity of the WM was evaluated by neurite orientation dispersion and density imaging and magnetization transfer saturation imaging. Tract-Based Spatial Statistics and the tracts-of-interest analysis were performed. Specific WM regions (corpus callosum, internal capsule, anterior thalamic radiation, corona radiata, superior longitudinal fasciculus, forceps minor, and inferior fronto-occipital fasciculus) were selected in the tracts-of-interest analysis. RESULTS In Tract-Based Spatial Statistics, the high-CAVI group showed a significantly lower myelin volume fraction value in the broad WM and significantly higher radial diffusivity and isotropic volume fraction values in the corpus callosum, forceps minor, inferior fronto-occipital fasciculus, internal capsule, corona radiata, and anterior thalamic radiation than the low-CAVI group. In tracts-of-interest analysis using multivariate linear regression, significant associations were found between the mean CAVI and radial diffusivity in the anterior thalamic radiation and the corona radiata; isotropic volume fraction in the anterior thalamic radiation and the corona radiata; and myelin volume fraction in the superior longitudinal fasciculus (P < .05). Additionally, partial correlation coefficients were observed for the significant associations of executive function with radial diffusivity and myelin volume fraction (P < .05). CONCLUSIONS Arterial stiffness could be associated with demyelination rather than axonal degeneration.

Abstract
Abstract
Background
While advances in PAH-specific therapies have substantially improved survival, there is still an unmet need to improve long-term outcomes in PAH.
Purpose
The UNISUS study is the first head-to-head superiority study in PAH, comparing the time to morbidity or mortality (M/M) with macitentan 75 mg vs macitentan 10 mg in PAH patients.
Methods
UNISUS, an ongoing multicentre, prospective, double-blind (DB), adaptive, event-driven superiority study randomises PAH patients 1:1 to receive macitentan 75 mg or macitentan 10 mg, with a target enrolment of ∼900 patients. Efficacy and safety are continuously assessed by an independent data monitoring committee (IDMC), who advises on pre-specified adaptive changes in study conduct, including expansion of the study population. An independent clinical event committee adjudicates all M/M events. The initial population was restricted to patients in functional class (FC) II/III, aged 18–75 years and excluded those with portopulmonary hypertension (PoPH) and those who were PAH treatment-naïve or receiving a prostanoid analogue. Stable (≥3 months) background PAH-therapy may be maintained, except for endothelin receptor agonists (ERAs), which must be stopped the day before initiating study drug. The study is comprised of a screening period, a 4-week run-in period (if ERA treatment-naïve or on sub-optimal ERA dose), and an event-driven DB treatment period, followed by a 2-year open-label extension with macitentan 75 mg. Initiation of macitentan 75 mg occurs after a 4-week up-titration step with macitentan 37.5 mg (Figure 1). The primary endpoint is time to first on-treatment M/M event, defined as first of: all-cause death, PAH-related hospitalisation, or PAH-related disease progression (confirmed ≥15% decrease in 6-minute walk distance (6MWD) and either FC worsening or addition of PAH therapy). Other endpoints include change from baseline to Week 24 in 6MWD and PAH-SYMPACT symptom scores; time to PAH-related hospitalisation or death; time to all-cause death (may be supplemented with data from an external control arm derived from the CARE PAH study [NCT04955990]); and the safety and tolerability of the study drugs. Figure 2 shows planned assessments and sub-studies. To maximise patient retention, add-on PAH therapies are allowed after a M/M event and, for patients at risk of withdrawing and unable to attend visits, the investigator may consider options for reduced follow-up.
Results
After 60 patients had been exposed for ≥8 weeks, the IDMC reviewed unblinded safety/tolerability data and recommended to expand recruitment from the restricted population to the target population (i.e., including patients: with PoPH, in FC II–IV, from any PAH therapy background [including naïve], aged ≥18 years).
Conclusion
UNISUS is the first head-to-head superiority study in PAH; with over 200 patients enrolled, it is currently recruiting the target population.

Abstract
BACKGROUND Prophylactic splenectomy for hilar lymph node (#10) dissection has shown no survival benefit for patients with proximal advanced gastric cancer that does not invade the greater curvature. However, the survival benefit of prophylactic splenectomy for proximal advanced gastric cancer invading the greater curvature side, particularly for clinically negative #10 lymph node metastasis (#10[-]) cases remains controversial. METHODS This multi-institutional retrospective study enrolled 146 consecutive patients with proximal advanced gastric cancers invading the greater curvature side with clinical #10(-) who underwent R0 total gastrectomy. For 33 of these patients, splenectomy was performed, and the remaining 113 underwent spleen-preservation gastrectomy. Short- and long-term results were compared between the splenectomy and spleen-preservation groups, with the incidence of #10 metastasis in the splenectomy group and recurrence in the spleen-preservation group compared. RESULTS In the splenectomy group, longer operative time, greater blood loss, more frequent postoperative abdominal infection, and longer hospital stay were observed than in the spleen-preservation group. The two groups exhibited no differences in median relapse-free survival time (31.1 vs 59.8 months; P = 0.684) or median overall survival time (64.9 vs 65.1 months; P = 0.765). The pathologic #10 lymph node metastasis rate was 3% in the splenectomy group, and the #10 lymph node recurrence rate was 2.7% in the spleen-preservation group. CONCLUSIONS Prophylactic splenectomy showed more frequent postoperative morbidities and a longer hospital stay than spleen preservation, without any long-term survival benefits.

Abstract
We present a feasibility study for the high-redshift galaxy part of the Science Verification Campaign with the 220-440 GHz deshima 2.0 integrated superconducting spectrometer on the ASTE telescope. The first version of the deshima 2.0 chip has been recently manufactured and tested in the lab. Based on these realistic performance measurements, we evaluate potential target samples and prospects for detecting the [CII] and CO emission lines. The planned observations comprise two distinct, but complementary objectives: (1) acquiring spectroscopic redshifts for dusty galaxies selected in far-infrared/mm-wave surveys; (2) multi-line observations to infer physical conditions in dusty galaxies.

Abstract
Patients with vancomycin-resistant Enterococcus (VRE) colonization should be managed in an isolation room with contact precautions. We herein report a patient whose colorectal carriage of VRE was successfully decolonized using concomitant bowel irrigation with polyethylene glycol, probiotics, and oral antimicrobials, linezolid and orally-administered daptomycin, for release from isolation and contact precautions. We therefore would like to suggest a potential strategy for managing patients with VRE colonization.

Abstract
OBJECTIVES This study aimed to (1) develop the physical fitness age, which is the biological age based on physical function, (2) evaluate the validity of the physical fitness age for the assessment of sarcopenia, and (3) examine the factors associated with the difference between physical fitness age and chronological age. DESIGN Cross-sectional study. SETTING AND PARTICIPANTS Community-dwelling older adults and outpatients. MEASUREMENTS A formula for calculating the physical fitness age was created based on the usual walking speed, handgrip strength, one-leg standing time, and chronological age of 4,076 older adults from the pooled data of community-dwelling and outpatients using the principal component analysis. For the validation of the physical fitness age, we also used pooled data from community-dwelling older adults (n = 1929) and outpatients (n = 473). Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 consensus. The association of D-age (the difference between physical and chronological ages) with cardiovascular risk factors, renal function, and cardiac function was examined. RESULTS The receiver operating characteristic analysis, with sarcopenia as the outcome, showed that the area under the curve (AUC) of physical fitness age was greater than that of chronological age (AUC 0.87 and 0.77, respectively, p < 0.001). Binomial logistic regression analysis revealed that the D-age was significantly associated with sarcopenia after adjustment for covariates (odds ratio 1.22, 95% confidence interval 1.19-1.26; p <0.001). In multivariate linear regression analysis with D-age as the dependent variable, D-age was independently associated with a history of diabetes mellitus (or hemoglobin A1c as a continuous variable), obesity, depression, and low serum albumin level. D-age was also correlated with estimated glomerular filtration rate derived from serum cystatin C, brain natriuretic peptide, and ankle-brachial index, reflecting some organ function and arteriosclerosis. CONCLUSIONS Compared to chronological age, physical fitness age calculated from handgrip strength, one-leg standing time, and usual walking speed was a better scale for sarcopenia. D-age, which could be a simple indicator of physical function, was associated with modifiable factors, such as poor glycemic control, obesity, depressive symptoms, and malnutrition.

Abstract
BACKGROUND AND PURPOSE Hypertension may be related to alterations of the glymphatic system, a waste metabolite drainage system in the brain. We aimed to investigate analysis along the perivascular space index changes in elderly subjects with hypertension. MATERIALS AND METHODS Diffusion-weighted images were acquired from 126 subjects, including 63 subjects with hypertension (25 men and 38 women; mean age, 72.45 years) and 63 age- and sex-matched controls (25 men and 38 women; mean age, 72.16 years). We calculated the analysis along the perivascular space index as a ratio of the mean of x-axis diffusivities in the projection and association areas to the mean of y-axis diffusivity in the projection area and z-axis diffusivity in the association area. The left, right, and mean analysis along the perivascular space indices of both hemispheres were compared between the hypertension and control groups using a Mann-Whitney U test. The Spearman correlation coefficient was used to assess the correlation between the left, right, and mean ALPS indices and blood pressure and pulse pressure. RESULTS The left (P = .011) and mean (P = .024) analysis along the perivascular space indices of the hypertension group were significantly lower than that of the control group. The left, right, and mean analysis along the perivascular space indices of all subjects were significantly negatively correlated with blood pressure values (r = -0.200 to -0.278, P = .002-0.046) and pulse pressure values (r = -0.221 to -0.245, P = .006-0.013). CONCLUSIONS Our results are consistent with a model in which hypertension causes glymphatic dysfunction.

Abstract
PATIENTS AND METHODS Patients with gastric cancer who underwent laparoscopic-assisted pylorus-preserving gastrectomy (LAPPG group)or laparoscopic-assisted distal gastrectomy(LADG group)between January 2010 and December 2019 were reviewed and their postoperative nutritional status and long-term outcomes retrospectively evaluated. RESULTS In total, 83 patients(LAPPG group, n=23; LADG group, n=60)were included. Weight loss rates 1, 6, 12, and 24 months postoperatively in the LAPPG and LADG groups were 5.7% and 7.1%, 6.6% and 9.6%, 5.8% and 10.1%, and 5.2% and 8.7%, respectively. The LADG group exhibited a significantly higher weight loss than the LAPPG group at 6, 12, and 24 months (p=0.007, 0.002, and 0.022, respectively). No recurrence was observed in either group within 5 years of surgery. The 5- year overall survival rate of patients with pathological Stage Ⅰ cancer( LAPPG group, n=23, LADG group, n=51) was higher in the LAPPG group than in the LADG group(100% vs 82.9%, p=0.027). There were 6 cases of death from other diseases in the LADG group(pneumonia, n=2, other cancer, n=2, postoperative bleeding, n=1, and heart failure, n=1)but none in the LAPPG group. CONCLUSION The weight loss after LAPPG was significantly lower than that after LADG. Furthermore, the former showed a good prognosis without death from other diseases, such as pneumonia.

Abstract
A 90-year-old woman diagnosed with stage IV gastric cancer (pT4a[SE]N2M1 [P, CY1]) after distal gastrectomy for her tarry stool was treated with S-1 monotherapy for 7 months, nab-PTX monotherapy for 3 months, and wPTX+RAM therapy for 3 months. Ascending colon tumor was revealed as peritoneal recurrence treated via right hemicolectomy. The nivolumab therapy was started as the fourth treatment. As the tumor progressed, sIL-2R, a destruction product of regulatory T cell surface antigens, tended to increase and the lymphocyte count tended to decrease, with the sIL-2R/lymphocyte count ratio changing in parallel with CA19-9. Throughout the course after gastrectomy, NLR increased and LMR decreased as the tumor status and general condition worsened.

Abstract
BACKGROUND Long-term outcomes in gastric cancer patients with positive lavage cytology (CY1) are generally poor. This multi-institutional retrospective cohort study aims to evaluate the clinical significance of the neutrophil-lymphocyte ratio (NLR) and the lymphocyte-monocyte ratio (LMR) in CY1 gastric cancer patients. METHODS A total of 121 CY1 gastric cancer patients without other non-curative factors, who underwent macroscopically curative resection, were enrolled in this study. The cutoff values of preoperative NLR (pre-NLR), postoperative NLR (post-NLR), preoperative LMR (pre-LMR), and postoperative LMR (post-LMR) were defined by the Contal and O'Quigley method as 2.3, 3.0, 2.5, and 3.2, respectively. A Cox proportional hazard model was used to identify the independent prognostic factors among NLR, LMR, and other clinicopathological factors. RESULTS There were significant differences in the overall survival (OS) between the two groups: high post-NLR groups vs. low post-NLR group (median survival time, months) (10.9 vs. 22.8, P = 0.006) and high pre-LMR group vs. low pre-LMR group (21.3 vs. 11.0, P = 0.001). The LMR value elevated significantly after gastrectomy (P = 0.020), although not in the NLR value (P = 0.733). On multivariate analysis, high post-NLR (hazard ratio = 1.506; 95% confidence interval = 1.047-2.167; P = 0.027), low pre-LMR (1.773; 1.135-2.769, 0.012), and no postoperative chemotherapy (1.558; 1.053-2.305, 0.027) were found to be independent prognostic factors for adverse OS. CONCLUSIONS Because a combination of high post-NLR and low pre-LMR may be an adverse prognostic marker in resectable CY1 gastric cancer patients, it is necessary to conduct a prospective trial to confirm a useful perioperative chemotherapeutic regimen for these patients.

Abstract
BACKGROUND The predictive factors for discontinuation of S-1 administration and prognostic factors in elderly patients with pStage II/III gastric cancer receiving S-1 adjuvant chemotherapy remain unclear. METHODS Between January 2004 and December 2016, 80 elderly gastric cancer patients (≥70 years) undergoing curative D2 gastrectomy were enrolled in this study. Predictive factors for completion of S-1 administration over 1 year, adverse events due to S-1 administration, and prognostic factors for overall survival (OS) and relapse-free survival (RFS) were evaluated. RESULTS Twenty-eight patients (35%) completed 8 courses of S-1. The median relative dose intensity was 82.1% (IQR 31.1-100%). The incidence rates of hematological and nonhematological adverse events were acceptable. Distal gastrectomy was an independent predictive factor for completion of S-1 administration (odds ratio [OR] 0.364; 95% confidence interval [CI] 0.141-0.939; p = 0.037). Higher postoperative neutrophil count/lymphocyte count (N/L) ratio and more advanced stage adversely influenced OS. Multivariate analysis revealed that a higher postoperative N/L ratio and more advanced stage adversely affected RFS. CONCLUSION To complete adjuvant S-1 administration to elderly patients with pStage II/III gastric cancer, total gastrectomy should be avoided if possible. A new regimen for elderly gastric cancer patients with higher postoperative N/L ratios and more advanced stage should be established.

Abstract
BACKGROUND/AIMS Traditional on-site monitoring of clinical trials via frequent site visits and 100% source data verification is cost-consuming, and it still cannot guarantee data quality effectively. Depending on the types and designs of clinical trials, an alternative would be combining several monitoring methods, such as risk-based monitoring and remote monitoring. However, there is insufficient evidence of its effectiveness. This research compared the effectiveness of risk-based monitoring with a remote monitoring system with that of traditional on-site monitoring. METHODS With a cloud-based remote monitoring system called beagle View®, we created a remote risk-based monitoring methodology that focused only on critical data and processes. We selected a randomized controlled trial conducted at Tohoku University Hospital and randomly sampled 11 subjects whose case report forms had already been reviewed by data managers. Critical data and processes were verified retrospectively by remote risk-based monitoring; later, all data and processes were confirmed by on-site monitoring. We compared the ability of remote risk-based monitoring to detect critical data and process errors with that of on-site monitoring with 100% source data verification, including an examination of clinical trial staff workload and potential cost savings. RESULTS Of the total data points (n = 5617), 19.7% (n = 1105, 95% confidence interval = 18.7-20.7) were identified as critical. The error rates of critical data detected by on-site monitoring, remote risk-based monitoring, and data review by data managers were 7.6% (n = 84, 95% CI = 6.2-9.3), 7.6% (n = 84, 95% confidence interval = 6.2-9.3), and 3.9% (n = 43, 95% confidence interval = 2.9-5.2), respectively. The total number of critical process errors detected by on-site monitoring was 14. Of these 14, 92.9% (n = 13, 95% confidence interval = 68.5-98.7) and 42.9% (n = 6, 95% confidence interval = 21.4-67.4) of critical process errors were detected by remote risk-based monitoring and data review by data managers, respectively. The mean time clinical trial staff spent dealing with remote risk-based monitoring was 9.9 ± 5.3 (mean ± SD) min per visit per subject. Our calculations show that remote risk-based monitoring saved between 9 and 41 on-site monitoring visits, corresponding to a cost of between US$13,500 and US$61,500 per trial site. CONCLUSION Remote risk-based monitoring was able to detect critical data and process errors as well as on-site monitoring with 100% source data verification, saving travel time and monitoring costs. Remote risk-based monitoring offers an effective alternative to traditional on-site monitoring of clinical trials.

Abstract
Abstract
Background
Extracorporeal Cardio-Pulmonary Resuscitation (E-CPR) is an effective tool for patients with refractory cardiac arrest (CA). Since VA-ECMO provides strong afterload, IABP is often used to increase left ventricular load. Recently, in Japan, the effectiveness of VA-ECMO in combination with IMPELLA, a forward flow mechanical circulatory support device (ECPELLA) is gaining attention.
Purpose
We investigated usefulness of ECPELLA in patients with refractory CA.
Method
We reviewed 133 patients that had E-CPR from January 2012 through January 2020 {mean age: 67±15 years, male 65%, Out of hospital Cardiac Arrest (OHCA) 35%, Acute coronary Syndrome (ACS) 54%}. We divided these patients into ECMO with IMPELLA (ECPELLA group), ECMO with IABP (IABP group) and ECMO alone (ECMO alone group). The primary endpoint is 30-day survival and good neurological prognosis defined as CPC (cerebral performance categories) 1 or 2.
Result
During the study period, of the 133 patients, there were 20 in the ECPELLA group, 78 in the IABP group, 35 in the ECMO alone group. There were no significant differences in age in all three groups. There were more males, shockable rhythm, OHCA and ACS in the ECPELLA and IABP groups compared to the ECMO alone group. But there was no significant difference between the ECPELLA and IABP groups. Compared with other groups, ECPELLA had the shortest time from cardiac arrest to ECMO placement. Regarding endpoints, the rate of 30-day survival and favorable neurological prognosis were higher in the ECPELLA group, followed by the IABP group and then the ECMO alone group. (ECPELLA: 55% vs. IABP: 23% vs. ECMO alone: 9%; P=0.0009, ECPELLA: 35% vs. IABP: 13% vs. ECMO alone: 9%; P=0.04) Next, Kaplan Meier analysis was performed to analyze 30-day all-cause mortality. The ECPELLA group had a significantly higher survival rate (P=0.01 by log-rank test). Multivariate cox proportional hazard analysis including the age, OHCA, shockable rhythm, ACS, Collapse-to-ECMO under 60 min revealed that the age (hazard ratio [HR], 1.28 (10 years increase), 95% confidence interval [CI], 1.08–1.53, P=0.004) and Collapse-to-ECMO under 60 min (HR, 0.37, 95% CI, 0.21–0.68, P=0.001) or ECPELLA (HR, 0.46, 95% CI, 0.20–0.694, P=0.03) were significantly associated with mortality.
Conclusion
ECPELLA used with E-CPR is an effective tool to improve mortality and neurologic status.

Abstract
Abstract
Background/Introduction
Immune checkpoint inhibitor (ICI)-associated myocarditis has a high mortality rate of approximately 50%. Clinical decompensation often occurs despite first-line treatment with corticosteroids. Factors associated with steroid failure are currently unknown.
Purpose
To identify predictors of steroid failure in patients with ICI-associated myocarditis.
Methods
We developed a web-based registry to collect and study 157 cases with clinical manifestations of ICI-associated myocarditis across 16 countries. Steroid failure was defined as patients who were escalated to immunomodulators after ≥1mg/kg daily dose of prednisone or had in-hospital death due to myocarditis despite ≥1mg/kg daily dose of prednisone. Steroid response was defined as all other patients treated with steroids without escalation to immunomodulators and without death due to myocarditis. A multivariate logistic model accounting for age and sex was used to predict association with steroid failure.
Results
Compared to steroid responsive cases, steroid failure was more likely to result in fulminant myocarditis (56.7% vs 19.6%, OR=5.37 [2.62–10.98] p<0.001) and all-cause in-hospital mortality (49.1% vs 12.9%, OR=6.50 [2.86–14.73] p<0.001) with shorter time from presentation to death (27.5 vs 43.0 days HR: 2.56 [1.45–4.50] p=0.001). When adjusting for age and sex, cases were more likely to be steroid-refractory if they were female (46.7% vs 30.1%, OR=2.77 [1.31–5.85] p=0.007), higher body mass index (27.2 vs 22.0, OR=1.09 [1.01–1.18] p=0.012), had higher intake creatine kinase (2800.5 vs 528.0 U/L, OR=1.48 [1.14–1.90] p=0.003) had higher intake troponin T (1.40 vs 0.25 ng/mL OR=1.63 [1.00–2.64] p=0.049), or had one or more concomitant non-cardiac immune-related adverse event (90.0% vs 74.2%, OR=3.10 [1.14–8.25] p<0.026). The only immune-related adverse events independently associated with steroid failure in myocarditis were myasthenia gravis-like syndrome (26.7% vs 8.2%, OR=3.84 [1.47–10.10] p=0.006) and myositis (45.0% vs 24.7%, OR=2.38 [1.16–4.92] p=0.018). Steroid failure was not significantly associated with cardiovascular or autoimmune history but was associated with a history of thymoma (12.0% vs 2.6%, OR=18.86 [0.10–356.7] p=0.05)
Conclusion(s)
Features such as female sex, high body mass index, and pre-existing thymoma as well as findings of elevated cardiac biomarkers and other non-cardiac immune-related adverse events – particularly myositis and myasthenia gravis-like syndrome – may represent a steroid-refractory phenotype of ICI-associated myocarditis. These results suggest that a multidisciplinary approach to diagnosing concomitant non-cardiac immune related adverse events is key to risk-stratifying ICI-associated myocarditis.

Abstract
Mental illness often affects and is affected by other diseases, such as cardiovascular disease, cancer, and AIDS/HIV infection, and people living with mental illness require additional common services and resource mobilization efforts. Therefore, we developed a mobile phone intervention and conducted a randomized controlled trial with 45 psychiatric outpatients with mental illnesses. Data from 39 individuals (intervention group: 20, control group: 19; mean [SD] age, 44.64 [14.12] years) were included in the analyses. The intervention involved the promotion of help-seeking behaviors by sending text messages, including information about social welfare services, for 3 months. After the intervention period, no significant differences were found in the proportion of help-seeking behaviors between the intervention and control groups. However, concerning the reason for not using social services, the proportion of participants who answered "I do not know how to use it" in the intervention group was significantly lower compared to the control group. More than 80% of participants in the intervention group reported that the text messaging service was helpful and useful, and they wanted more messages and information. This was the first randomized controlled trial to promote psychiatric patients' help-seeking behavior using text messaging. Moreover, the text messaging intervention was found to be cost-effective.

Abstract
BACKGROUND AND AIM Oral 5-aminosalicylic acid (5-ASA) is recommended for the therapy of mild to moderate intestinal Behçet's disease (BD). However, the induction remission efficacy and endoscopic outcomes of 5-ASA are unknown. We investigated remission induction at 8 weeks, endoscopic outcomes until 52 weeks, and event-free survival at 52 weeks in patients with intestinal BD treated with 5-ASA. METHODS Forty-one patients with intestinal BD were treated with oral 5-ASA. Clinical remission was evaluated with the Crohn's disease activity index (CDAI). The endoscopic response was evaluated using the modified global gastrointestinal endoscopic assessment scores. Rescue therapy-free survival and surgery-free survival at 52 weeks were estimated, and predictive factors for a clinical response at weeks 8 and 52 were identified. RESULTS Seven patients (17%) withdrew 5-ASA early (≤ 8 weeks) because of adverse events. At week 8, clinical efficacy could be accurately evaluated in 28 patients, and the response and remission rates were 61% and 57%, respectively, using the CDAI. Endoscopic evaluation was achieved in 17 patients up to 52 weeks, and the endoscopic response and remission rates were 71% and 35%, respectively. The probabilities of rescue therapy-free survival and surgery-free survival were 73% and 100%, respectively, at 52 weeks in all 41 patients. The predictive factors for therapeutic effectiveness at week 8 were a higher baseline C-reactive protein level and CDAI, but they were negative predictive factors for a 52-week response. CONCLUSIONS 5-ASA is effective for clinical and endoscopic induction and maintaining a response in patients with mild to moderate intestinal BD.

Abstract
BACKGROUND Nosocomial infections by respiratory viruses undetected by rapid tests are not often diagnosed. For paediatric patients with background diseases, nosocomial infection could be fatal. AIM To determine the relationship between developing symptoms by respiratory viruses undetectable by rapid tests and respiratory risks and to improve the management of infection control. METHODS Two episodes of nosocomial infection by human bocavirus (HBoV) and human rhinovirus (HRV) were retrospectively investigated in a tertiary hospital paediatric ward in Japan. Viruses were identified by polymerase chain reaction to determine infection control management. When viruses of the same species were detected from different patients, the virus homology was investigated. The relationship between respiratory risks and developing symptoms was statistically investigated. FINDINGS Three and four patients with respiratory risks in the HBoV and HRV outbreaks, respectively, developed respiratory symptoms. The nucleotide sequences of two patients in the HBoV outbreak and all four patients in the HRV outbreak were phylogenetically close. In both outbreaks, the patients with respiratory risks developed significantly more symptoms than those without any risk (P = 0.035 and 0.018, respectively). After the patients with respiratory infection were separated from those with respiratory risks, no additional nosocomial infection occurred. CONCLUSION Patients with respiratory risks easily develop respiratory symptoms and acquire severe symptoms of nosocomial infection by those viruses. In a paediatric ward, we should adopt not only standard precautions but also isolation management of the patients with respiratory symptoms, even if they have negative results in rapid tests.

Abstract
SummaryThe influence of OKY-046, a selective thromboxane synthase inhibitor, on prostanoid formation in healthy human subjects was studied. Vehicle (5% glucose solution) or OKY-046 in 5% glucose solution at 15 μg kg−1 min−1 was intravenously administered to five male healthy volunteers for 6 h. Platelet aggregation and thromboxane B2 (TXB2) formation induced by collagen and arachidonic acid were suppressed by the infusion of OKY-046, while both were not affected by the infusion of vehicle. Urinary excretion of 11-dehydro-thromboxane B2, one of major urinary metabolites of thromboxane A2 (TXA2) was decreased by the infusion of OKY-046, while that of 2,3-dinor-6-keto-prostaglandin F1α, one of major urinary metabolites of prostacyclin (PGI2) was increased. The present study demonstrated that the infusion of OKY-046 improved the balance of TXA2/PGI2 into antithrombotic state in healthy subjects. It was also suggested that endogenously produced (probably platelet-derived) endoperoxides could be redirected into prostacyclin in vivo.

Abstract
In order to be able to use the aroma hand massage as a skill that can be done by a nurse who does not have a special aromatherapy technique, we examine antistress effects of simplified aroma hand massage for healthy subjects. We evaluated the anti-stress action of aroma hand massage and the different components of the procedure in 20 healthy women in their twenties. We used autonomic nervous function measured via electrocardiogram as an index of stress. After conducting a baseline electrocardiogram, we induced stress in the participants by asking them to spend 30 minutes completing Kraepelin’s arithmetic test. We then administered various treatments and examined the anti-stress effects. Kraepelin’s test significantly increased sympathetic nervous function and significantly reduced parasympathetic nervous function. Compared with massage without essential oil or aroma inhalation, aroma hand massage significantly increased parasympathetic nervous function and significantly decreased sympathetic nervous function. The effect of the aroma hand massage persisted when the procedure was simplified. The anti-stress action of the aroma hand massage indicates that it might have beneficial application as a nursing technique. There are several limitations in this study; ambiguities of low component/high component ratio of heart rate variability and bias by small subjects groups of the same women.

Abstract
Standing-up motion is an important daily activity. It has been known that elderly and post-stroke patients have difficulty in performing standing-up motion. The standing-up motion is retrained by therapists to maximize independence of the elderly and post-stroke patients, but it is not clear how the elderly and post-stroke patients control their redundant muscles to achieve standing-up motion. This study employed the concept of muscle synergy to analyze how healthy young adults, healthy elderly people and post-stroke patients control their muscles. Experimental result verified that four muscle synergies can represent human standing-up motion. In addition, it indicated that the post-stroke patients shift the weights of muscle synergies to finish standing-up motion comparing to healthy subjects. Moreover, different muscle synergy structures were associated with the CoM and joint kinematics.

Abstract
Esophageal squamous cell carcinoma is a highly aggressive neoplasm and the sixth leading cause of global cancer-related death; the 5-year survival rate for esophageal cancer is only about 20%-25% for all stages. Therefore, improving the therapeutic effect is important. This study assessed whether low-dose hyperthermia (LDH) enhances the antitumor effects of chemotherapy. The antitumor effect of chemotherapy with/without LDH in the squamous cell carcinoma cell line SCCVII was evaluated. A comprehensive analysis was performed with real-time polymerase chain reaction (PCR) to study the hyperthermia-induced changes in the gene expression of SCCVII cell lines. In addition, the cytotoxic and apoptotic changes in the cells treated with LDH combined with/without 5-fluorouracil (5-FU) were measured. LDH combined with 5-FU (10 nM) strongly inhibited the cell growth of SCCVII, with flow cytometry showing an increased population of apoptotic cells. PCR showed that LDH promoted a 25.22-fold increase of p53 mRNA and 18.08-fold increase of Bax mRNA in vitro. MDR1 expression was decreased to 28.7% after LDH. This treatment can result in much higher efficacy of antitumor drugs. After LDH, the expressions of TS decreased to 12.06%, OPRT increased by 4.17-fold, and DPD did not change (1.03-fold). This transformations will induce susceptibility to 5-FU. LDH may be a useful enhancer of chemotherapy drugs for squamous cell carcinoma.

Abstract
This study explored ethical treatment decisions of healthcare professional students beginning their education. As part of a first-semester modern medicine and bioethics course, 311 students watched and discussed, in interprofessional groups, a video titled Dax's Case: Who Should Decide? regarding the treatment of a life-threatening infectious disease against Dax's wish. The students then discussed and made their decision regarding treating or not. Their decisions, recorded on a worksheet, were classified as "will treat" or "won't treat." Professional groups' decision patterns were compared using the chi-square test. Overall, 151 (71%) opinions from students were classified as "will treat," and 61 (29%) as "won't treat." Nursing students were more likely to decide "won't treat" (in line with Dax's preference); however, the majority of other professions' students favoured treatment (against Dax's wish). Given the students' limited exposure to profession-specific education, our preliminary study supports the notion that healthcare profession students hold different values that align with their chosen profession at the start of their studies.
