Abstract
Background The number of children with complex medical conditions has increased in recent decades. In this context, a complex chronic condition is characterized by multiple morbidities that require intensive or continuous health care according to the level of severity. Given their various health conditions, it is challenging to provide special education to these children, but there is still insufficient evidence regarding the practical experiences of educators. The aim of this study was to investigate special education teacher's perceptions, experiences, and challenges while developing interpersonal relationships and communicating with children who have complex chronic conditions. Methods We recruited and interviewed 21 special education school teachers in Japan. The transcripts of the interviews were analyzed using thematic analysis. Results Our analysis revealed four themes, including "searching for the meaning," "complex chronic conditions as a difficult reality," "widening experience for the future," and "priority for interacting with children." These themes reflect the perceptions, experiences, and challenges of the special education teachers. Conclusions In cases where children have severe functional limitations, it is more challenging to understand child-teacher interactions. This highlights the importance of searching for meaning in educational practices used among children with complex chronic conditions. Our findings may provide helpful insight into the experiences and challenges faced by special educators who engage with these children.

Abstract
Although oxytocin may provide a novel therapeutics for the core features of autism spectrum disorder (ASD), previous results regarding the efficacy of repeated or higher dose oxytocin are controversial, and the underlying mechanisms remain unclear. The current study is aimed to clarify whether repeated oxytocin alter plasma cytokine levels in relation to clinical changes of autism social core feature. Here we analyzed cytokine concentrations using comprehensive proteomics of plasmas of 207 adult males with high-functioning ASD collected from two independent multi-center large-scale randomized controlled trials (RCTs): Testing effects of 4-week intranasal administrations of TTA-121 (A novel oxytocin spray with enhanced bioavailability: 3U, 6U, 10U, or 20U/day) and placebo in the crossover discovery RCT; 48U/day Syntocinon or placebo in the parallel-group verification RCT. Among the successfully quantified 17 cytokines, 4 weeks TTA-121 6U (the peak dose for clinical effects) significantly elevated IL-7 (9.74, 95 % confidence interval [CI] 3.59 to 15.90, False discovery rate corrected P (PFDR) < 0.001), IL-9 (56.64, 20.46 to 92.82, PFDR < 0.001) and MIP-1b (18.27, 4.96 to 31.57, PFDR < 0.001) compared with placebo. Inverted U-shape dose-response relationships peaking at TTA-121 6U were consistently observed for all these cytokines (IL-7: P < 0.001; IL-9: P < 0.001; MIP-1b: P = 0.002). Increased IL-7 and IL-9 in participants with ASD after 4 weeks TTA-121 6U administration compared with placebo was verified in the confirmatory analyses in the dataset before crossover (PFDR < 0.001). Furthermore, the changes in all these cytokines during 4 weeks of TTA-121 10U administration revealed associations with changes in reciprocity score, the original primary outcome, observed during the same period (IL-7: Coefficient = -0.05, -0.10 to 0.003, P = 0.067; IL-9: -0.01, -0.02 to -0.003, P = 0.005; MIP-1b: -0.02, -0.04 to -0.007, P = 0.005). These findings provide the first evidence for a role of interaction between oxytocin and neuroinflammation in the change of ASD core social features, and support the potential role of this interaction as a novel therapeutic seed.

Abstract
The Hayabusa2 spacecraft delivered samples of the carbonaceous asteroid Ryugu to Earth. Some of the sample particles show evidence of micrometeoroid impacts, which occurred on the asteroid surface. Among those, particles A0067 and A0094 have flat surfaces on which a large number of microcraters and impact melt splashes are observed. Two impact melt splashes and one microcrater were analyzed to unveil the nature of the objects that impacted the asteroid surface. The melt splashes consist mainly of Mg-Fe-rich glassy silicates and Fe-Ni sulfides. The microcrater trapped an impact melt consisting mainly of Mg-Fe-rich glassy silicate, Fe-Ni sulfides, and minor silica-rich glass. These impact melts show a single compositional trend indicating mixing of Ryugu surface materials and impactors having chondritic chemical compositions. The relict impactor in one of the melt splashes shows mineralogical similarity with anhydrous chondritic interplanetary dust particles having a probable cometary origin. The chondritic micrometeoroids probably impacted the Ryugu surface during its residence in a near-Earth orbit.

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
Plastics have benefited our lives in many ways, but their long persistence in the environment causes serious problems. Rapid decomposition and detoxification of plastics after use are significant challenges. As a possible solution, biodegradable plastics have attracted attention, and for environmental risk assessment research on polymer toxicity, use of indicator organisms, like water fleas and fish, has increased globally. However, such research often focuses on standardized substances without considering changes in toxicity due to plastic degradation products. Additionally, tests generally focus on acute toxicity, while long-term effects on organismal reproduction and lifespan are largely unknown. Understanding the impact of degraded polymers on biological activities is crucial for accurate risk assessment. In this study, we investigated the biological toxicity of substances generated during degradation of polycaprolactone (PCL), a common biodegradable plastic, using the indicator organism, Daphnia magna. We examined PCL, oligocaprolactones (OCLs), and monomers resulting from polymer cleavage, as well as carbodiimides, added during polyester synthesis. As a result, PCL, which is insoluble in water, reduced individual survival and total number of offspring at an exposure concentration of 100 mg/L, while no toxicity was observed for water-soluble degradation products, OCLs, and monomers. Furthermore, carbodiimides, which are expected to be released during PCL degradation, showed strong toxicity, significantly reducing individual survival and total number of offspring at 0.1-10 mg/L. These findings suggest that changes in physical properties due to polymer degradation and release of additives can significantly alter their toxicity.

Abstract
BACKGROUND In Japan, genetic testing, surveillance, and risk-reducing surgery for hereditary breast and ovarian cancer (HBOC) syndrome have been covered by the Japanese national insurance system since April 2020. On the other hand, the current situation is that medical care, including surveillance of undiagnosed (cancer-free) patients, is self-funded even for individuals with HBOC. We report a case in which breast cancer was diagnosed at an early stage during surveillance for cancer-free HBOC at the patient's own expense, and risk-reducing surgery was performed at the same time as treatment for breast cancer. CASE PRESENTATION The patient was a 63-year-old woman. Her sister had a history of breast cancer in her 30s and was found to be a BRCA2 pathogenic variant carrier by genetic testing. The patient therefore presented to the genetic department of our hospital and underwent genetic testing (out-of-pocket). A pathogenic variant was found at the same site. During annual breast and ovarian surveillance at the patient's own expense, a physician with sufficient expertise in contrast-enhanced breast magnetic resonance imaging (MRI) noticed a change in the contrast enhancement pattern on breast MRI and performed needle biopsy, revealing ductal carcinoma in situ. At the request of the patient, she underwent concurrent contralateral risk-reducing mastectomy and risk-reducing salpingo-oophorectomy in addition to breast cancer treatment. CONCLUSIONS We encountered a case in which cancer treatment and risk-reducing surgery were performed at the same time for a pathogenic variant carrier who was very anxious about developing cancer. Surveillance of cancer-free BRCA1/2 mutation carriers and expansion of insurance coverage for surgery are important future issues.

Abstract
PURPOSE No standard approach other than oral care is available for preventing chemotherapy-induced stomatitis in patients with breast cancer. In this randomized, controlled phase 2 trial, we aimed to assess the efficacy and safety of a dexamethasone-based mouthwash in preventing chemotherapy-induced stomatitis in patients with early breast cancer. BASIC PROCEDURES Patients with breast cancer scheduled for epirubicin and cyclophosphamide (EC) or docetaxel and cyclophosphamide (TC) therapy were selected and allocated in a 1:1 ratio to the intervention and control groups. The intervention group received chemotherapy, oral care, and a dexamethasone-based mouthwash, whereas the control group received chemotherapy and oral care. The primary endpoint was the incidence of stomatitis. This was a phase 2 study, and the significance level for the analysis of the primary endpoint was set a priori at 0.2. MAIN FINDINGS Data pertaining to 58 patients in the control group and 59 patients in the intervention group were analyzed. Stomatitis incidence was 55% and 38% in the control and intervention groups, respectively (risk ratio, 0.68; 80% confidence interval, 0.52-0.88; P = .052). Stomatitis severity was lower in the intervention group than in the control group (P = .03). The proportion of patients who adhered to the mouthwash regimen was 87% (interquartile range, 67.8%-95.3%). No severe oral infections were observed. PRINCIPAL CONCLUSIONS The dexamethasone-based mouthwash safely reduced stomatitis incidence and severity in patients receiving chemotherapy for early breast cancer. Phase 3 clinical trials are warranted for validating our results.

Abstract
Regeneration of alveolar bone is an essential step in restoring healthy function following tooth extraction. Growth of new bone in the healing extraction socket can be variable and often unpredictable when systemic comorbidities are present, leading to the need for additional therapeutic targets to accelerate the regenerative process. One such target is the TAM family (Tyro3, Axl, Mertk) of receptor tyrosine kinases. These proteins have been shown to help resolve inflammation and maintain bone homeostasis and thus may have therapeutic benefits in bone regeneration following extraction. Treatment of mice with a pan-TAM inhibitor (RXDX-106) led to accelerated alveolar bone fill following first molar extraction in a mouse model without changing immune infiltrate. Treatment of human alveolar bone mesenchymal stem cells with RXDX-106 upregulated Wnt signaling and primed the cells for osteogenic differentiation. Differentiation of human alveolar bone mesenchymal stem cells with osteogenic media and TAM-targeted inhibitor RXDX-106 (pan-TAM), ASP-2215 (Axl specific), or MRX-2843 (Mertk specific) showed enhanced mineralization with pan-TAM or Mertk-specific inhibitors and no change with Axl-specific inhibitor. First molar extractions in Mertk-/- mice had increased alveolar bone regeneration in the extraction socket relative to wild type controls 7 d postextraction. Flow cytometry of 7-d extraction sockets showed no difference in immune cell numbers between Mertk-/- and wild type mice. RNAseq of day 7 extraction sockets showed increased innate immune-related pathways and genes associated with bone differentiation in Mertk-/- mice. Together, these results indicate that TAM receptor signaling, specifically through Mertk, can be targeted to enhance bone regeneration after injury.

Abstract
Loss of E-cadherin expression is a poor prognostic factor in patients with breast cancer. Breast cancer cells co-cultured with adipocytes reportedly promote E-cadherin attenuation and tumor progression. The current study aimed to investigate the association of reduced E-cadherin expression with adipose tissue invasion (ATI) and prognosis in breast cancer. Surgical specimens were collected from 188 women with invasive ductal carcinoma of the breast who had undergone surgery without neoadjuvant treatment. We compared E-cadherin expression in ATI and invasive front (IF) using immunohistochemistry with ImageJ. Reduced E-cadherin expression was detected not only in the ATI area but also in the IF, and the degree of reduced E-cadherin expression was positively correlated with both areas. In patients with lymph node metastasis compared to those without, E-cadherin expression was reduced and this reduction was associated with poor recurrence-free survival. We concluded that E-cadherin expression is reduced not only at the ATI area but also at the IF of the tumor. Reduced E-cadherin expression is a clear prognostic factor for breast cancer. Hence, future research is warranted for establishing an objective and quantitative E-cadherin staining assay that will allow clinical use of E-cadherin as a prognostic factor.

Abstract
Carbonaceous meteorites contain diverse soluble organic compounds. These compounds formed in the early solar system from volatiles accreted on tiny dust particles. However, the difference in the organic synthesis on respective dust particles in the early solar system remains unclear. We found micrometer-scale heterogeneous distributions of diverse CHN1-2 and CHN1-2O compounds in two primitive meteorites: the Murchison and NWA 801, using a surface-assisted laser desorption/ionization system connected to a high mass resolution mass spectrometer. These compounds contained mutual relationships of ± H2, ± CH2, ± H2O, and ± CH2O and showed highly similar distributions, indicating that they are the products of series reactions. The heterogeneity was caused by the micro-scale difference in the abundance of these compounds and the extent of the series reactions, indicating that these compounds formed on respective dust particles before asteroid accretion. The results of the present study provide evidence of heterogeneous volatile compositions and the extent of organic reactions among the dust particles that formed carbonaceous asteroids. The compositions of diverse small organic compounds associated with respective dust particles in meteorites are useful to understand different histories of volatile evolution in the early solar system.

Abstract
The aim of this study was to evaluate the knowledge and educational needs with regard to hereditary breast and ovarian cancer among nurses working in breast cancer care in the Nagasaki Prefecture. In breast cancer care, the identification of patients at risk for hereditary breast and ovarian cancer is necessary for the implementation of genetic testing and counseling. Nurses should be involved in this process, since they play a crucial role in the care of patients with breast cancer. However, the knowledge regarding hereditary breast and ovarian cancer among nurses working in oncology care in Japan has not been assessed. The design of this study is cross-sectional design. We distributed 597 surveys to nurses working in breast cancer care. The surveys assessed the nurses' demographic data, their current knowledge and practices regarding cancer genetics and hereditary breast and ovarian cancer, and their attitude and preferences regarding learning about the condition. We received 317 valid replies. Nurses had limited knowledge about hereditary breast and ovarian cancer characteristics: 41.6% reported that they do not know about the condition, whereas less than 10% knew its characteristics. However, nurses were aware of hereditary breast and ovarian cancer significance and were willing to learn about it: 91% wished to learn about the condition, and 88.6% wanted to participate in study group meetings. Further, nurses' preferences regarding educational programs were clarified. Overall, our results show that educational programs should be implemented to advance nurses' knowledge of hereditary breast and ovarian cancer characteristics.

Abstract
BACKGROUND Sedating children for magnetic resonance imaging (MRI) requires special consideration. The 2018 revision of social insurance allows additional fees to be calculated for pediatric MRIs performed under sedation in Japan. The number and trend of actual claims since this addition was established is unknown. METHODS To analyze the claims of additional fees for pediatric sedated MRI imaging after fiscal year (FY) 2018, the actual claims of the addition in inpatient and outpatient practice was analyzed using publicly-available data from the Ministry of Health, Labour and Welfare (MHLW). We analyzed the calculation rate for all MRI scans. Annual changes in the actual number and calculation rate were analyzed. The ratio of the number of additional fees to the overall number of pediatric radiological procedures was used to examine the geographic disparity. RESULTS The number of calculations from FY 2018 to FY 2020 was available; in FY 2020, only 1347 additions were calculated, corresponding to 0.35% of the total number of MRI scans. The number of fees showed a decreasing trend. Most cases were in the 0-4 years age group: however, there were a few cases in the 10-14 years age group without such a decrease. The relative number of calculations by prefecture showed a disparity of up to 14 times. CONCLUSIONS The requirements for the addition of pediatric MRI sedation are strict and not fully utilized in pediatric sedation for MRI. Measures such as relaxing the requirements for the fee are needed to make MRI-related sedation safer. (249/250words) .

Abstract
BACKGROUND Fatty acid-binding protein 4 (FABP4) is secreted from adipocytes and macrophages in adipose tissue and acts as an adipokine. It has recently been reported that FABP4, but not liver-type FABP (L-FABP/FABP1), is also expressed in injured glomerular endothelial cells and infiltrating macrophages in the glomerulus and that urinary FABP4 (U-FABP4) is associated with proteinuria and kidney function impairment in nephrotic patients. However, the link between glomerular FABP4 and U-FABP4 has not been fully addressed in IgA nephropathy (IgAN). METHODS We investigated the involvement of FABP4 in human and mouse IgAN. RESULTS In patients with IgAN (n = 23), the ratio of FABP4-positive area to total area within glomeruli (G-FABP4-Area) and U-FABP4 were positively correlated with proteinuria and were negatively correlated with eGFR. In 4-28-week-old male grouped ddY mice, a spontaneous IgAN-prone mouse model, FABP4 was detected in glomerular endothelial cells and macrophages, and G-FABP4-Area was positively correlated with urinary albumin-to-creatinine ratio (r = 0.957, P < 0.001). Endoplasmic reticulum stress markers were detected in glomeruli of human and mouse IgAN. In human renal glomerular endothelial cells, FABP4 was induced by treatment with vascular endothelial growth factor and was secreted from the cells. Treatment of human renal glomerular endothelial cells or mouse podocytes with palmitate-bound recombinant FABP4 significantly increased gene expression of inflammatory cytokines and endoplasmic reticulum stress markers, and the effects of FABP4 in podocytes were attenuated in the presence of an anti-FABP4 antibody. CONCLUSION FABP4 in the glomerulus contributes to proteinuria in IgAN, and U-FABP4 level is a useful surrogate biomarker for glomerular damage in IgAN.

Abstract
Abstract
Background: The semi-dry dot-blot (SDB) method, a diagnostic procedure for detecting lymph node (LN) metastases using an anti-cytokeratin (CK) antibody, is based on the theory that epithelial components, such as CK, are not found in normal LNs. Thus, metastases are diagnosed according to the presence of CK in the lavage fluid of sectioned LNs. We prospectively evaluated novel SDB kits that use a newly developed anti-CK19 antibody and an automatic reader for diagnosing sentinel LN metastases in patients with breast cancer as a multi-center study. Methods: We obtained 924 sentinel LNs dissected from 405 patients with breast cancer between January 2021 and December 2021 at six institutes in Japan. We excluded patients who underwent neoadjuvant chemotherapy and neoadjuvant endocrine therapy. LNs were sectioned at 2-mm intervals and washed with phosphate-buffered saline. Cells suspended in the lavage fluid of sectioned LNs were centrifuged and lysed to extract protein. The extracted protein was applied to the SDB kit to diagnose LN metastasis using an automatic absorbance reader. Hematoxylin and eosin (H&E) stained and washed LNs were blindly examined by pathologists using intraoperative and permanent histological examination. Diagnoses based on SDB kit and automatic reader findings were compared with diagnoses made by permanent histological examination of paraffin-embedded H&E-stained sections of LNs. Primary endpoints were the sensitivity, specificity, and overall agreement of the SDB kit for distinguishing macrometastases from non-macrometastases. Results: Ninety-four of the 924 LNs were assessed as macrometastases, 40 as micrometastases, and 790 as isolated tumor cells by histological examination. Compared with patients with non-macrometastases, those with macrometastases had significantly younger age (p< 0.01), larger primary tumor (p< 0.01), higher nuclear grade (p=0.04), increased lymphatic invasion (p< 0.01), and increased venous invasion (p=0.01). Using a borderline CK19 absorbance of 11.9 milli-absorbance for detecting macrometastases with an area under the curve of 0.989, the sensitivity, specificity, and overall agreement of the SDB kit were 94.7%, 98.3%, and 97.9%, respectively. Moreover, the sensitivity, specificity, and overall agreement of the intraoperative histological examination compared with permanent histological examination for distinguishing macrometastases from non-macrometastases were 91.4%, 99.1%, and 98.3%, respectively. Furthermore, the kits and automatic reader yielded diagnoses within approximately 20 min at a cost of < 30 USD for the SDB kit and < 3,000 USD for the automatic reader. Conclusions: The kits with an automatic reader used in our study were accurate, quick, and cost-effective in diagnosing LN metastases without the loss of LN tissue and were particularly useful for distinguishing macrometastases. We plan to make the SDB kit and automatic reader commercially available worldwide soon.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
Samples of the carbonaceous asteroid (162173) Ryugu were collected and brought to Earth by the Hayabusa2 spacecraft. We investigated the macromolecular organic matter in Ryugu samples and found that it contains aromatic and aliphatic carbon, ketone, and carboxyl functional groups. The spectroscopic features of the organic matter are consistent with those in chemically primitive carbonaceous chondrite meteorites that experienced parent-body aqueous alteration (reactions with liquid water). The morphology of the organic carbon includes nanoglobules and diffuse carbon associated with phyllosilicate and carbonate minerals. Deuterium and/or nitrogen-15 enrichments indicate that the organic matter formed in a cold molecular cloud or the presolar nebula. The diversity of the organic matter indicates variable levels of aqueous alteration on Ryugu's parent body.

Abstract
Without a protective atmosphere, space-exposed surfaces of airless Solar System bodies gradually experience an alteration in composition, structure and optical properties through a collective process called space weathering. The return of samples from near-Earth asteroid (162173) Ryugu by Hayabusa2 provides the first opportunity for laboratory study of space-weathering signatures on the most abundant type of inner solar system body: a C-type asteroid, composed of materials largely unchanged since the formation of the Solar System. Weathered Ryugu grains show areas of surface amorphization and partial melting of phyllosilicates, in which reduction from Fe3+ to Fe2+ and dehydration developed. Space weathering probably contributed to dehydration by dehydroxylation of Ryugu surface phyllosilicates that had already lost interlayer water molecules and to weakening of the 2.7 µm hydroxyl (-OH) band in reflectance spectra. For C-type asteroids in general, this indicates that a weak 2.7 µm band can signify space-weathering-induced surface dehydration, rather than bulk volatile loss.

Abstract
Taxanes are key drugs for patients with breast cancer. A major adverse effect of taxanes is peripheral neuropathy (PN). To investigate the ability of compression therapy using sleeves and stockings to prevent PN due to the taxane docetaxel, we conducted a single-center historical control trial. Patients receiving docetaxel at 75 mg/m2 every 3 weeks for 4 cycles as first-line chemotherapy for breast cancer were eligible. PN was evaluated using the common terminology criteria for adverse events version 4.0. The primary endpoint was the incidence of allgrade PN until 3 weeks after the fourth docetaxel administration. We evaluated 26 patients in the intervention group and compared their data to those collected retrospectively from 52 patients treated with docetaxel without compression. Neither the incidence of all-grade PN until 3 weeks after the fourth docetaxel administration (63.5% in the control group vs. 76.9% in the intervention group, p=0.31) nor that of PN grade ≥ 2 (13.5% vs. 15.4%, p=0.99) differed between the groups. In this study, the efficacy of compression therapy using sleeves and stockings to prevent PN induced by docetaxel was not demonstrated. Further clinical studies including medications or intervention are needed to reduce the incidence and severity of PN induced by chemotherapy.

Abstract
Background: Lymphedema may develop when axillary lymph node dissection (ALND) injures and obstructs the lymph ducts in the upper limb. In patients with breast cancer, lymphedema is difficult to treat and can cause arm swelling, heaviness, and restricted movement. We aimed to identify the prevalence and risk factors for lymphedema after ALND in patients with breast cancer. Methods and Results: This retrospective study included 175 patients with breast cancer who underwent ALND in the Nagasaki University Hospital, Japan, between 2005 and 2018. Lymphedema was defined as symptomatic arm swelling with a >2-cm difference in the arm circumference between the affected and contralateral arms. Patients were divided into two groups according to the presence or absence of lymphedema. Surgical and pathological findings were compared between the two groups. Univariate and multivariate analyses were performed, including the chi-square test, Student's t-test, and logistic regression analysis. Lymphedema was prevalent in 20% of the study participants, and the mean time interval from surgery to development of lymphedema was 479 days. In the univariate analysis, a body mass index of >26 kg/m2, smoking, radiotherapy (RT), and dissection of >18 axillary lymph nodes (ALNs) significantly increased the risk of lymphedema. In the multivariate analysis, smoking, RT, and dissection of >18 ALNs significantly increased the risk of lymphedema. Conclusions: The prevalence of lymphedema in our study was 20%. Our findings suggest that smoking, RT, and dissection of >18 ALNs are risk factors for lymphedema. Aggressive and empiric ALND might be associated with axillary lymph duct damage.

Abstract
Abstract
Background
Recent clinical trials are testing strategies for short (1–3 months) dual antiplatelet therapy (DAPT) following newer-generation drug-eluting stent (DES) placement. However, the safety of short DAPT regimens is not supported by biological evidence in humans.
Purpose
We sought to evaluate early pathologic responses to newer-generation DES by comparing abluminal biodegradable polymer-coated DES (BP-DES) with circumferential durable polymer-coated DES (DP-DES) in human autopsy cases.
Methods
The study included a total of 37 coronary lesions with thin strut newer-generation DES (DP-DES=23 [XIENCE=18, Resolute Integrity=5] and BP-DES=14 [SYNERGY=9, Ultimaster=5]) with duration of implantation <90 days in 25 autopsy cases. The process of stent healing was precisely evaluated for every single strut in association with underlying tissue characteristics. The degree of strut coverage was defined as follows: grade 0 (bare struts), grade 1 (struts covered with thrombus, fibrin, or other tissues or cells without endothelium), grade 2 (struts covered with single-layered endothelium without underlying smooth muscle cell layers), and grade 3 (struts covered with endothelium and underlying smooth muscle cell layers) (Figure 1).
Results
Duration of implantation was similar in lesions with DP-DES and those with BP-DES (median=20 vs. 17 days). A total of 1986 struts (DP-DES=1261, BP-DES=725) were pathologically analyzed. Focal grade 2 coverage was observed as early as 5 days after the implantation in both stents. Multilevel mixed-effects ordered logistic regression model demonstrated that BP-DES exhibited greater strut coverage compared with DP-DES (odds ratio; 3.50, 95% CI; 1.31–9.41, P=0.013), which remained significant after adjustment for duration of implantation and underlying tissue characteristics (odds ratio; 2.64, 95% CI; 1.04–6.68, P=0.040). The time course of vessel healing assessed as predictive probability of strut coverage (grade 0–3) stratified by duration of implantation is shown in Figure 2. Predictive probability of grade 2 and 3 coverage was comparably limited at 30 days (DP-DES=17.7% vs. BP-DES=29.0%) and increased at 90 days (DP-DES=76.1% vs. BP-DES=85.9%). Both stents showed few inflammation and similar degree of fibrin deposition.
Conclusions
The current first pathologic study on early biological responses to newer-generation DES in humans demonstrated that single-layered endothelial coverage begins in days following the stent placement, and abluminal BP-DES potentially exhibit faster strut coverage with smooth muscle cell infiltration than circumferential DP-DES. Nevertheless, vessel healing remains suboptimal at 30 days in both DP- and BP-DES, which progresses with time to become substantial at 90 days. Our results suggest that very short duration of DAPT for 1 month should be applied with caution, taking into account the trade-off between bleeding and thrombotic risks.

Abstract
PURPOSES Fine-needle aspiration cytology (FNAC) is a specific and important test used for the diagnosis of thyroid gland cancer. We developed a thyroid gland phantom using original manufacturing techniques and direct three-dimensional (3D) printing. The aim of this study was to confirm the effectiveness of this phantom by collecting data to evaluate puncture training. METHODS Data from 45 ultrasonography-guided thyroid nodule FNAC procedures performed on our thyroid phantom were evaluated in our department. The first group comprised qualified physicians who specialized in thyroid gland treatment (group A; n = 10). The second and third groups comprised senior and junior residents (group B; n = 8 and group C; n = 12; respectively). The fourth group comprised students (group D; n = 15). We measured the times taken by these groups to complete each task. RESULTS The skills of all participants in groups B, C, and D improved after using this phantom involving the major (parallel)- (0.47 ± 0.07) and short (orthogonal)-axes (0.52 ± 0.07) methods (P < 0.001). The number of erroneous punctures decreased from 53 to 3. CONCLUSIONS Our original phantom improved the puncture skills of students and junior doctors and was suitable as a tailored training model for practicing thyroid gland transfixion.

Abstract
UNLABELLED Millimetre-sized primordial rock fragments originating from asteroid Ryugu were investigated using high energy X-ray fluorescence spectroscopy, providing 2D and 3D elemental distribution and quantitative composition information on the microscopic level. Samples were collected in two phases from two sites on asteroid Ryugu and safely returned to Earth by JAXA's asteroid explorer Hayabusa2, during which time the collected material was stored and maintained free from terrestrial influences, including exposure to Earth's atmosphere. Several grains of interest were identified and further characterised to obtain quantitative information on the rare earth element (REE) content within said grains, following a reference-based and computed-tomography-assisted fundamental parameters quantification approach. Several orders of magnitude REE enrichments compared to the mean CI chondrite composition were found within grains that could be identified as apatite phase. Small enrichment of LREE was found for dolomite grains and slight enrichment or depletion for the general matrices within the Ryugu rock fragments A0055 and C0076, respectively.

Abstract
Prolonged isolated thrombocytopenia (PIT) is a complication following allogeneic hematopoietic cell transplantation that results in prolonged transfusion dependence. Recently, the efficacy of a thrombopoietin receptor agonist (eltrombopag) against PIT has been reported in adults; however, there are few reports in children. A 4-year-old male pediatric patient diagnosed with congenital pure red cell aplasia underwent allogeneic hematopoietic cell transplantation. Neutrophil engraftment was observed on post-transplant Day 26; however, platelet counts remained <10 × 109/L. Transfusions were required 1−2 times a week for at least 4 months. On post-transplant Day 124, oral eltrombopag (up to 2.4 mg/kg/day) was initiated. Thereafter, the platelet counts were maintained at ≥10 × 109/L, and the patient became transfusion independent. At 2 years and 6 months after the oral administration, no chromosomal abnormalities, thromboembolism, or myelofibrosis was observed. Thus, eltrombopag can be a potential treatment option for pediatric PIT.

Abstract
BACKGROUND There is growing evidence that neuroinflammation may contribute to schizophrenia neuropathology. Elevated pro-inflammatory cytokines are evident in the midbrain from schizophrenia subjects, findings that are driven by a subgroup of patients, characterised as a "high inflammation" biotype. Cytokines trigger the release of antibodies, of which immunoglobulin G (IgG) is the most common. The level and function of IgG is regulated by its transporter (FcGRT) and by pro-inflammatory IgG receptors (including FcGR3A) in balance with the anti-inflammatory IgG receptor FcGR2B. Testing whether abnormalities in IgG activity contribute to the neuroinflammatory abnormalities schizophrenia patients, particularly those with elevated cytokines, may help identify novel treatment targets. METHODS Post-mortem midbrain tissue from healthy controls and schizophrenia cases (n = 58 total) was used to determine the localisation and abundance of IgG and IgG transporters and receptors in the midbrain of healthy controls and schizophrenia patients. Protein levels of IgG and FcGRT were quantified using western blot, and gene transcript levels of FcGRT, FcGR3A and FcGR2B were assessed using qPCR. The distribution of IgG in the midbrain was assessed using immunohistochemistry and immunofluorescence. Results were compared between diagnostic (schizophrenia vs control) and inflammatory (high vs low inflammation) groups. RESULTS We found that IgG and FcGRT protein abundance (relative to β-actin) was unchanged in people with schizophrenia compared with controls irrespective of inflammatory subtype. In contrast, FcGRT and FcGR3A mRNA levels were elevated in the midbrain from "high inflammation" schizophrenia cases (FcGRT; p = 0.02, FcGR3A; p < 0.0001) in comparison to low-inflammation patients and healthy controls, while FcGR2B mRNA levels were unchanged. IgG immunoreactivity was evident in the midbrain, and approximately 24% of all individuals (control subjects and schizophrenia cases) showed diffusion of IgG from blood vessels into the brain. However, the intensity and distribution of IgG was comparable across schizophrenia cases and control subjects. CONCLUSION These findings suggest that an increase in the pro-inflammatory Fcγ receptor FcGR3A, rather than an overall increase in IgG levels, contribute to midbrain neuroinflammation in schizophrenia patients. However, more precise information about IgG-Fcγ receptor interactions is needed to determine their potential role in schizophrenia neuropathology.

Abstract
12103 Background: Stomatitis, a frequent adverse event in patients undergoing chemotherapy, can lead to pain, ulcers, bleeding, and malnutrition due to reduced oral intake, which not only deteriorates quality of life but may also result in dose reduction or interruption of chemotherapy. However, there is currently no standard approach for preventing chemotherapy-induced stomatitis. Therefore, this study aimed to assess the efficacy and safety of a dexamethasone-based mouthwash for preventing chemotherapy-induced stomatitis in patients with early breast cancer. Methods: We conducted a multicenter, randomized, controlled phase II trial. Patients with early-stage breast cancer scheduled for epirubicin and cyclophosphamide (EC) or docetaxel and cyclophosphamide (TC) therapies were allocated in a 1:1 ratio to the intervention and control groups. The sample size was set to 120 cases based on the following assumptions: stomatitis incidence of 50% in the control group and 30% in the intervention group, alpha error of 0.2, one-sided power of 0.9, and dropout proportion of 10%. The intervention group received chemotherapy, oral care, and a dexamethasone-based mouthwash (10 mL, 0.1 mg/mL; swish for 2 min and spit, 4 times daily for 9 weeks), and the control group received chemotherapy and oral care. The primary endpoint was the incidence of stomatitis that was compared between the two groups. Results: There were 60 patients in the control group and 61 in the intervention group. One patient in the control group and two in the study group withdrew consent; one patient in the control group was excluded because of discontinuation of the first cycle of chemotherapy and unavailability of data related to the incidence of stomatitis. Finally, the data of 58 patients in the control group and 59 in the intervention group were analyzed. There were no differences in age and chemotherapy regimens between the groups. The incidence of stomatitis was 55% in the control group and 38% in the intervention group (risk ratio 0.68; 80% confidence interval, 0.52 – 0.88; p = 0.052). The grade of stomatitis (0/1/2/3) was significantly lower in the study group (intervention group vs. control group: 37/13/7/2 vs. 26/16/7/9, p = 0.03). There were no differences in the duration of stomatitis between the groups. Moreover, the percentage of patients who adhered to the mouthwash regimen was 87% (range, 14% – 100%). There were no significant differences in the occurrence of other adverse events between the groups, and only one case of oral candidiasis was observed in the intervention group. Conclusions: Dexamethasone-based mouthwash safely reduced the incidence and severity of stomatitis in patients receiving chemotherapy (EC/TC) for early breast cancer.

Abstract
1049 Background: Asymptomatic metastatic breast cancer (mBC) is often detected using tumor marker or imaging tests in Japan. At the ASCO 2019, we reported on mBC detection, the distribution of symptomatic and asymptomatic disease by subtype (abstract e12568). We aimed to determine whether there are differences in post-recurrence survival (PRS), and treatment between asymptomatic and symptomatic MBCs, and identify factors associated with PRS. Methods: We performed a multicenter, retrospective analysis of patients with mBC treated in our hospitals from 2008 to 2018. Patients were divided into asymptomatic and symptomatic MBCs to compare their prognosis by breast cancer (BC) subtypes: luminal (hormone receptor positive/human epidermal growth factor 2 [HER2] negative), HER2 (any hormone receptor/HER2 positive), and triple-negative (TN) (hormone receptor negative/HER2 negative). Results: Of 204 patients with mBC (114 asymptomatic, 90 symptomatic), PRS was longer in asymptomatic mBC than in symptomatic mBC (median survival: 55 months vs. 29 months; p < 0.001) and tended to have longer overall survival (OS) (110 months vs 72 months, respectively; p = 0.09). In multivariate analysis, TN, recurrence-free survival (RFS), multiple metastasis sites, and symptomatic disease were independently predictive of PRS (Table). In luminal and HER2, PRS trended higher in the asymptomatic group than in the symptomatic group (luminal: 54 months vs. 41 months; p = 0.08, HER2: 71 months vs. 27 months; p = 0.09), but without significant difference in OS (luminal: 112 months vs. 124 months; p = 0.91, HER2: 113 months vs. 72 months; p = 0.40). In the luminal group, 13 patients (11%) were treated with cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. The median PRS was 80 months for luminal patients with three factors — longer than 4 years of RFS, a single metastasis site, and asymptomatic disease. The duration of endocrine therapy did not differ between groups; however, the patients with luminal BC in the asymptomatic group had longer chemotherapy than those in the symptomatic group. In TN, PRS was very short (asymptomatic, 28 months; symptomatic, 10.5 months; p = 0.01). Conclusions: We demonstrated that asymptomatic MBC and symptomatic MBC differed in terms of subtypes, prognosis, and duration of chemotherapy in the luminal group. Therefore, unique treatment strategy for asymptomatic or symptomatic MBC should be developed. [Table: see text]

Abstract
Abstract
Although intranasal oxytocin is expected to be a novel therapy for the core symptoms of autism spectrum disorder, which has currently no approved medication, the efficacy of repeated administrations was inconsistent, suggesting that the optimal dose for a single administration of oxytocin is not optimal for repeated administration.
The current double-blind, placebo-controlled, multicentre, crossover trial (ClinicalTrials.gov Identifier: NCT03466671) was aimed to test the effect of TTA-121, a new formulation of intranasal oxytocin spray with an enhanced bioavailability (3.6 times higher than Syntocinon® spray, as assessed by area under the concentration–time curve in rabbit brains), which enabled us to test a wide range of multiple doses, on autism spectrum disorder core symptoms and to determine the dose–response relationship. Four-week administrations of TTA-121, at low dose once per day (3 U/day), low dose twice per day (6 U/day), high dose once per day (10 U/day), or high dose twice per day (20 U/day), and 4-week placebo were administered in a crossover manner. The primary outcome was the mean difference in the reciprocity score (range: 0–14, higher values represent worse outcomes) on the Autism Diagnostic Observation Schedule between the baseline and end point of each administration period. This trial with two administration periods and eight groups was conducted at seven university hospitals in Japan, enrolling adult males with high-functioning autism spectrum disorder. Enrolment began from June 2018 and ended December 2019. Follow-up ended March 2020.
Of 109 males with high-functioning autism spectrum disorder who were randomized, 103 completed the trial. The smallest P-value, judged as the dose–response relationship, was the contrast with the peak at TTA-121 6 U/day, with inverted U-shape for both the full analysis set (P = 0.182) and per protocol set (P = 0.073). The Autism Diagnostic Observation Schedule reciprocity score, the primary outcome, was reduced in the TTA-121 6 U/day administration period compared with the placebo (full analysis set: P = 0.118, mean difference = −0.5; 95% CI: −1.1 to 0.1; per protocol set: P = 0.012, mean difference = −0.8; 95% CI: −1.3 to −0.2). The per protocol set was the analysis target population, consisting of all full analysis set participants except those who deviated from the protocol. Most dropouts from the full analysis set to the per protocol set occurred because of poor adherence to the test drug (9 of 12 in the first period and 8 of 15 in the second period). None of the secondary clinical and behavioural outcomes were significantly improved with the TTA-121 compared with the placebo in the full analysis set.
A novel intranasal spray of oxytocin with enhanced bioavailability enabled us to test a wide range of multiple doses, revealing an inverted U-shape dose–response curve, with the peak at a dose that was lower than expected from previous studies. The efficacy of TTA-121 shown in the current exploratory study should be verified in a future large-scale, parallel-group trial.

Abstract
Aim:
Proprotein convertase subtilisin/kexin type 9 (PCSK9) degrades the low-density lipoprotein (LDL) receptor, leading to hypercholesterolemia and cardiovascular risk. Treatment with a statin leads to a compensatory increase in circulating PCSK9 level. Anagliptin, a dipeptidyl peptidase-4 (DPP-4) inhibitor, was shown to decrease LDL cholesterol (LDL-C) levels to a greater extent than that by sitagliptin, another DPP-4 inhibitor, in the Randomized Evaluation of Anagliptin versus Sitagliptin On low-density lipoproteiN cholesterol in diabetes (REASON) trial. We investigated PCSK9 concentration in type 2 diabetes mellitus (T2DM) and the impact of treatment with anagliptin or sitagliptin on PCSK9 level as a sub-analysis of the REASON trial.
Methods:
PCSK9 concentration was measured at baseline and after 52 weeks of treatment with anagliptin (
n
=122) or sitagliptin (
n
=128) in patients with T2DM who were receiving statin therapy. All of the included patients had been treated with a DPP-4 inhibitor prior to randomization.
Results:
Baseline PCSK9 level was positively, but not significantly, correlated with LDL-C and was independently associated with platelet count and level of triglycerides. Concomitant with reduction of LDL-C, but not hemoglobin A1c (HbA1c), by anagliptin, PCSK9 level was significantly increased by treatment with sitagliptin (218±98 vs. 242±115 ng/mL,
P
=0.01), but not anagliptin (233±97 vs. 250±106 ng/mL,
P
=0.07).
Conclusions:
PCSK9 level is independently associated with platelet count and level of triglycerides, but not LDL-C, in patients with T2DM. Anagliptin reduces LDL-C level independent of HbA1c control in patients with T2DM who are on statin therapy possibly by suppressing excess statin-mediated PCSK9 induction and subsequent degradation of the LDL receptor.

Abstract
Mycobacteriosis caused by Mycobacterium spp. causes economic damages to the world aquaculture industry. In mammals, mycolic acids contained in the cell wall of Mycobacterium spp. are presented by CD1b molecule as lipid antigens and induce cell-mediated immunity (CMI). Here, we investigated CMI responses against the mycolic acids of Mycobacterioides salmoniphilum in a CD1-lacking teleost fish, rainbow trout. After stimulation of trout leukocytes with mycolic acids, the number and percentage of CD8α+ T cells increased. Fish immunized with mycolic acids showed an up-regulation of IFN-γ. Further, in vitro re-stimulation of leukocytes derived from immunized fish resulted in proliferation of CD8α+ cells. These data suggest that mycolic acids are recognized as lipid antigens resulting in an activation of rainbow trout CD8α+ cells and up-regulation of the Th1 cytokine IFN-γ. The mycolic acids are promising candidates for vaccines to activate CD8α+ T cells against fish mycobacteriosis.

Abstract
INTRODUCTION Although aromatase inhibitors (AIs) are typical drugs for cancer treatment-induced bone loss, their effects on the bone microstructure remain unclear. In this study, we evaluated changes in the bone mineral density (BMD) and bone microstructure associated with AI treatment using high-resolution peripheral quantitative computed tomography (HR-pQCT) in patients with early breast cancer. MATERIALS AND METHODS This prospective, single-arm, observational study included non-osteoporotic, postmenopausal women with hormone receptor-positive breast cancer. Patients underwent dual-energy X-ray absorptiometry (DXA), HR-pQCT, and tartrate-resistant acid phosphatase-5b (TRACP-5b) or procollagen type-I N-terminal propeptide measurements at baseline and 6 and 12 months after AI therapy. The primary endpoint was changes in the total volumetric BMD (Tt.vBMD), trabecular vBMD (Tb.vBMD), and cortical vBMD (Ct.vBMD) longitudinally at the distal radius and tibia. RESULTS Twenty women were included (median age 57.5 years; range 55-72 years). At 12 months, HR-pQCT indicated a significant decrease in the Tt.vBMD (median distal radius - 5.3%, p < 0.01; distal tibia - 3.2%, p < 0.01), Tb.vBMD (- 3.2%, p < 0.01; - 1.0%, p < 0.05, respectively), and Ct.vBMD (- 3.2%, p < 0.01; - 2.7%, p < 0.01, respectively). Estimated bone strength was also significantly decreased. The DXA BMD value in the total hip (p < 0.01) and femoral neck (p = 0.03), but not in the lumbar spine, was significantly decreased. The TRACP-5b levels was significantly negatively associated with changes in the Tt.vBMD in both the distal radius and tibia (r = - 0.53, r = - 0.47, respectively) CONCLUSION: Postmenopausal women who received AIs for early breast cancer experienced significant trabecular and cortical bone deterioration and a decrease in estimated bone strength within only 1 year.

Abstract
BACKGROUND/AIM To compare operative results between venous puncture (P) with real-time ultrasonography vs. cut-down (CD) with preoperative ultrasonography for totally implantable central vein access device (TICVAD) implantation performed by residents (R) vs. senior surgeons (S). PATIENTS AND METHODS Adult oncologic patients (n=268) undergoing TICVAD implantations were retrospectively compared between 172 Ps and 96 CDs. Then, we compared Ps performed by R (P-R, n=131) and S (P-S, n=41) and CDs performed by R (CD-R, n=59) and S (CD-S, n=37). RESULTS Median operation times were 40 min in the P group and 53.5 min in the CD group, and times were significantly shorter for P-S and CD-S. Completion rates were comparable for each method and each surgeon. Intraoperative complication rates were 3.8% (P-R), 2.4% (P-S), and 0% (CD-R and CD-S). CONCLUSION P with real-time ultrasonography did not avoid complications compared to CD with preoperative ultrasonography. The latter performed safely even by residents.

Abstract
ABSTRACT Matsumoto M, Satoh, K, Kushi, H, Hamuro, K, Sakurai, M, Saito, H, Tanaka, R, Saito, T, Kohda, N, and Hamada, K. Salivary immunoglobulin A secretion rate during peak period conditioning regimens in triathletes. J Strength Cond Res 35(5): 1389-1396, 2021-Triathletes often feel unwell during the conditioning period (peak period) leading up to a race. The aim of this study was to evaluate the factors relevant to the condition of athletes and their impact on mucosal immune responses and the salivary immunoglobulin A (IgA) secretion rate. This study recruited college student triathletes (33 men and 7 women) who participated in an Olympic distance race. For each subject, the salivary IgA rate was measured continuously for 1 month before the race (peak period). Data on physical activity during the peak period were calculated in metabolic equivalents, and the relationships between these factors and the salivary IgA secretion rate were evaluated. The average amount of physical activity was highest during the 2- to 3-week period before the race, at 744.7 ± 51.5 kcal expended per day. In subjects who, on average, expended more than 1,000 kcal·d-1 in physical activity between 12 and 14 days before the race, the salivary IgA secretion rate was significantly reduced compared with the value at 1 week before the race (p < 0.05). On the day before the race, a further reduction was observed (p < 0.1). The salivary IgA secretion rate was decreased by high-intensity exercise during the peak period in advance of a race; this was associated with a loss of optimal condition just before the race.

Abstract
Abstract
Background: Adjuvant endocrine therapy for 5-10 years reduces breast cancer (BC) mortality in women with hormone receptor-positive BC. However, aromatase inhibitors (AIs) decrease bone mineral density (BMD), and increase fractures, joint stiffness, and joint pain. Although dual energy X-ray absorptiometry (DXA) is widely used to assess BMD, it is a two-dimensional method and thus cannot analyze trabecular and cortical bone microstructure. High-resolution peripheral quantitative computed tomography (HR-pQCT) allows in vivo analysis of peripheral bone microarchitecture with high spatial resolution and low radiation exposure. We used HR-pQCT to evaluate changes in volumetric bone density and microstructure consisting of trabecular and cortical bone associated with AI treatment in patients with early BC. Methods: This was a prospective single-center observational study of nonosteoporotic, postmenopausal women with hormone receptor-positive BC, whose baseline DXA lumber spine and femoral neck T-scores were > −2.5. All patients were scheduled to receive DXA and HR-pQCT at baseline and at 6 and 12 months after starting AI therapy. The primary endpoint was to examine changes in total volumetric BMD (Tt. vBMD), trabecular volumetric BMD (Tb. vBMD), cortical volumetric BMD (Ct. vBMD) change at the distal radius and the distal radius between baseline and 6 and 12 months after starting endocrine therapy. Results: Of the 20 women in the study (median age: 57.5 years; range: 55-72 years), 8 had undergone chemotherapy before registration. Their mean change in Tt. vBMD between baseline and 1 year were distal radius: −5.7% (SD: 2.5%, P<0.01); distal tibia: −3.8% (SD: 1.8%, P<0.01), Tb. vBMD distal radius: −4.0% (SD: 3.9%, P<0.01); distal tibia: −0.9% (SD: 2.4%, P<0.05), Ct. vBMD distal radius: −3.1% (SD: 1.6%, P<0.01); distal tibia: −2.9% (SD: 1.7%, P<0.01). Furthermore, at 1 year in trabecular bone, mean trabecular bone volume fraction (p<0.01), trabecular thickness (p<0.05), and trabecular number (p<0.01) were significantly decreased, and trabecular separation (p<0.01) increased, in both the distal radius and tibia. At 1 year in cortical bone, mean changes in cortical thickness (p<0.01) and cortical bone area (p<0.01) were significantly decreased in both the distal radius and tibia; however, the endocortical perimeter of cortical bone did not significantly change and cortical porosity (p<0.05) was significantly greater than that at baseline. At 1 year, DXA decreased at the total hip (−4.4%, P<0.01) and femoral neck (−0.6%, P=0.03) compared with baseline. However, no significant difference was seen in median values for lumbar spine BMD at 1 year, or for tartrate-resistant acid phosphatase-5b (TRACP-5b) or procollagen type-I N-terminal propeptide (PINP). Conclusion: Postmenopausal women who took AIs for early BC experience volumetric bone density decline and both trabecular and cortical bone deterioration. A decade of AI treatment is a standard treatment for early BC; however, healthcare professionals should monitor bone health during and after these treatments.

Abstract
Abstract
Background: The semi-dry dot-blot (SDB) method, a diagnostic procedure for detecting lymph node (LN) metastases using anti-cytokeratin (CK) antibody, is based on the theory that epithelial components such as CK are not found in normal LNs. Thus, metastases are diagnosed on basis of the presence of CK in lavage fluid of sectioned LNs. We prospectively evaluated novel SDB kits that use a newly developed anti-CK19 antibody and an automatic reader for diagnosing LN metastases in patients with breast cancer. Methods: We obtained 117 LNs dissected from 58 patients with breast cancer between January 2020 and June 2020 at Nagasaki University Hospital. These were sliced at 2-mm intervals and washed with phosphate-buffered saline. Cells suspended in the lavage fluid of sliced LNs were centrifuged and lysed to extract protein. The extracted protein was applied to the SDB kit to diagnose LN metastasis using an automatic reader that evaluates absorbance. Hematoxylin and eosin (H&E) stained washed LNs were blindly examined by pathologists. Diagnoses based on SDB kit and automatic reader findings were compared with diagnoses made by histological examination of paraffin-embedded H&E stained sections of the LNs. Results: Six of the 117 LNs were assessed as positive and 111 as negative by histological examination. With a borderline CK19 absorbance of 50 milli-absorbance (mAbs) for detecting LN metastases excluding isolated tumor cells, the sensitivity, specificity, and overall agreement of the SDB kit were 66.7%, 99.1%, and 97.4%, respectively. Two patients with false-negatives had micrometastases of 0.6 and 0.5 mm in diameter. There was contamination by breast epithelial tissue in one false-positive case. With a borderline CK19 absorbance of 100 mAbs for distinguishing macrometastases from micrometastases, the sensitivity, specificity, and overall agreement of the SDB kit were 100%, 100%, and 100%, respectively. Furthermore, the kits and the automatic reader yielded diagnoses in approximately 20 min at a cost of less than 30 USD. Conclusions: The kits with an automatic reader used in our study were accurate, quick, and cost-effective in diagnosing LN metastases without loss of LN tissue, and were especially useful for detecting distinguish macrometastases. We plan to start a prospective multi-center study to evaluate clinical performance soon.

Abstract
Survival of patients with breast cancer can be prolonged by treatment with drugs, particularly new molecular-targeted drugs. However, these agents can be expensive and such treatments can be “an economic burden.” In this ongoing trial, we aim to assess the usefulness of ChemoCalc, a software package for calculating drug costs, to help patients understand the financial outlays. In this multicenter, randomized controlled phase 2 trial, 106 patients with advanced breast cancer will be assigned to either the “ChemoCalc” or “Usual Explanation” group. Treatment using ChemoCalc will be discussed with patients in the ChemoCalc group, whereas standard treatments, without using ChemoCalc, will be discussed with patients in the Usual Explanation group. Subsequently, the participants will decide the treatment and complete a five-grade evaluation questionnaire; those in the Usual Explanation group will receive information about ChemoCalc. Investigators will report if patients subsequently decide to change treatments. The primary endpoint will be the scores of two key questions compared between the groups: “Did you understand the cost of treatment in today's discussion?” and “Do you think the cost of treatment is important in choosing a treatment?“. The secondary endpoints will be to compare discrepancies between treatments recommended by physicians and those selected by patients, the time required for discussion, other questionnaire factors, and the relationship between Comprehensive Score for Financial Toxicity tool and treatment selection. This will be the first randomized controlled trial to assess the efficacy of software to help patients understand drug cost estimates and whether it subsequently affects treatment choice. This study will be conducted according to the CONSORT statement. All participants will sign a written consent form. The study protocol was reviewed and approved by the Clinical Research Review Board of Nagasaki University (19070801). The protocol (version 1) was designed and will be conducted in accordance with the Declaration of Helsinki (1964) and the Ethical Guidelines for Medical and Health Research Involving Human Subjects (2017). The findings will be disseminated through scientific and professional conferences, and in peer-reviewed journals.

Abstract
INTRODUCTION Management of breast cancer patients undergoing hemodialysis (HD) is difficult because of a lack of evidence about drug selection, dose adjustment, and surgical procedures. We herein present a case of metastatic breast cancer in a patient undergoing HD. PRESENTATION OF CASE A 58-year-old Japanese woman with breast cancer undergoing HD underwent total mastectomy of the left breast and left axillary dissection. Histopathological examination revealed invasive ductal carcinoma, and the diagnosis was pT2N3cM0 Stage ⅢC. Immunostaining of the resected specimen indicated that the tumor was estrogen receptor-positive, progesterone receptor-negative, human epithelial growth factor receptor 2-positive, and the Ki-67 labeling index was 70%. A postoperative positron emission tomography/computed tomography (PET/CT) scan indicated fluorodeoxyglucose uptake in the supraclavicular nodes. She received adjuvant therapy of epirubicin and cyclophosphamide followed by docetaxel, trastuzumab (T-mab) and radiation therapy. However, she developed multiple liver metastases during adjuvant T-mab and hormone therapy. Therefore, her regimen was changed to trastuzumab emtansine (T-DM1) as first-line therapy, T-mab, pertuzumab (P-mab), and eribulin as second-line therapy, and T-mab, P-mab, and weekly paclitaxel as third-line therapy. Eventually, she was administered fourth-line treatment of T-mab, P-mab, and vinorelbine because of adverse events. She has survived more than 25 months after the initial detection of recurrence of breast cancer and maintained quality of life. CONCLUSION We report a case of breast cancer in a patient undergoing HD. It is very difficult to identify the appropriate drugs and dosages in patients undergoing HD to improve survival and quality of life.

Abstract
We assessed the usefulness of ChemoCalc, a software package for calculating drug costs, in helping patients understand these costs. We randomly assigned, in a 1 : 1 ratio, 20 women who had undergone surgery for early breast cancer to a group that discussed adjuvant treatment with their physicians using the ChemoCalc software (ChemoCalc group) or a group that discussed adjuvant treatment without ChemoCalc (Usual Explanation group). The participants completed a five-grade evaluation questionnaire after these discussions. The primary endpoint was the intergroup comparison of the questionnaire scores regarding participants' understanding of their treatment-associated drug costs. Median age was not significantly different between the ChemoCalc group and Usual Explanation group (57 vs. 50, respectively; p=0.27). Patients in the ChemoCalc group had a significantly higher perceived level of understanding of the drug cost than those in the Usual Explanation group (5 [4-5] vs. 2.5 [1-5], respectively; p=0.002). Scores related to the patients' perception that understanding drug costs is an important part of breast cancer treatment were also higher in the ChemoCalc group than the Usual Explanation group (5 [2-5] vs. 3 [1-5], respectively; p=0.049). ChemoCalc was found to be useful for understanding drug costs.

Abstract
PURPOSE The asterion is frequently used as an anatomical landmark to determine the location of a keyhole in the lateral suboccipital approach used in craniotomies. However, the asterion may not be ideal because of large individual differences among patients. We examined a simple and safe method for determining an optimal keyhole position (KP) using the digastric groove as a new landmark in the lateral suboccipital approach. METHODS Thirty-three patients with trigeminal neuralgia who underwent surgery in our institute between April 2014 and December 2018 were included. The groove line (GL) was designed accurately, extending the digastric groove on the surface of the occipital bone, as the x-axis. The y-axis was depicted from the posterior edge of the digastric groove (the groove point: GP) vertical to the GL. The x-y coordinates represented the distances from GP on each axis. The x-y coordinates of median edge of the transverse-sigmoid sinus (TSJ point), asterion, and the intersection of the GL and transverse sinus (the transverse point: TP) were investigated, based on intraoperative findings and recorded videos. RESULTS The x-y coordinated of the TSJ point were (23.9±3.9, 7.2±3.6). In all patients, the TSJ point was located superior to the GL. The x-y coordinates of the asterion were (27.3±6.0, 8.9±4.1), and in 28 of the 33 patients, their coordinates exceeded the TSJ points. The x-coordinate of the TP was 29.5±4.5, and was located behind the TSJ point on the GL in all patients. The shortest distance between the TSJ points and TP was approximately 3mm. According to these measurements, we decided that the optimal KP would be at 20mm from the GP, subjacent to the GL. CONCLUSIONS Our methods of using the GL as a new surgical landmark for setting the optimal KP is simple, safe, and useful.
