Abstract
The pathogenesis of malignant mesothelioma (MM) has been extensively investigated, focusing on stress derived from reactive oxygen species. We aimed to identify diagnostic biomarkers of MM by analyzing proteins in formalin-fixed paraffin-embedded specimens using liquid chromatography-mass spectrometry. We extracted proteins from formalin-fixed paraffin-embedded sections of MM tissues (n = 7) and compared their profiles with those of benign mesothelial tissues (n = 4) and alveolar tissue (n = 1). Proteomic data were statistically assessed and profiled using principal component analysis. We were successful in the classification of MM and healthy tissue. The levels of superoxide dismutase 2 (SOD2), an enzyme that converts superoxide anion into oxygen and hydrogen peroxide, and thioredoxin (TXN), which plays a crucial role in reducing disulfide bonds in proteins, primarily contributed to the classification. Other redox-related proteins, such as pyruvate dehydrogenase subunit X, and ceruloplasmin also contributed to the classification. Protein-protein interaction analysis demonstrated that these proteins play essential roles in MM pathogenesis. Immunohistochemistry revealed that TXN levels were significantly lower, whereas SOD2 levels were significantly higher in MM and lung cancer tissues than in controls. Proteomic profiling suggested that MM tissues experienced increased exposure to hydrogen peroxide and other reactive oxygen species. Combining immunohistochemistry for TXN and SOD2 allows for differentiation among MM, lung cancer, and control tissues; hence, TXN and SOD2 may be promising MM biomarkers and therapeutic targets.

Abstract
BACKGROUNDS Evaluation of gait posture using a three-dimensional motion analysis system (3DMAS) revealed that elderly patients with adult spinal deformity (ASD) experience pelvic anteversion while walking. The purpose of this study was to investigate the influence of changes in pelvic anteversion during gait on walking ability and physical function in patients with ASD. METHODS Fifty-four patients with ASD aged 50 years or older who were admitted to our hospital between March 2016 and December 2021 were included in the study. The 6-min walking distance (6MWD) was used to evaluate walking ability, and trunk and hip extensor strength were measured to evaluate physical function in the subjects. The 3DMAS was used to measure the subject's changes in pelvic anteversion during gait. After measuring the changes in pelvic anteversion, the median value of the study subjects was calculated, according to which the subjects were divided into two groups (small anteversion [S] group, large anteversion [L] group). Walking ability and physical function were compared between the two groups. RESULTS The number of subjects in each group was 27. Comparisons of walking ability and physical function between the groups revealed significant differences in 6MWD (S group, 333.6 ± 111.2 m; L group, 238.0 ± 106.3 m) and hip extensor strength (S group, 15.8 ± 3.8 kgf; L group, 13.4 ± 4.4 kgf). No significant differences regarding trunk extensor strength were observed between the groups (S group, 15.2 ± 4.0 kgf; L group, 12.9 ± 4.8 kgf). CONCLUSION The results of the present study revealed that ASD patients with greater pelvic anteversion associated with walking have lower walking ability and physical function. These results suggest the importance of evaluating the posture of ASD patients not only by using radiographic findings but also by assessing movement, such as gait posture.

Abstract
BACKGROUND The molecular pathology of diffuse large B cell lymphoma (DLBCL) has been extensively studied. Among DLBCL subtypes, the prognosis of CD5-positive DLBCL is worse than that of CD5-negative DLBCL, considering the central nervous system relapse and poor response to R-CHOP therapy. However, the molecular mechanisms underlying the tumorigenesis and progression of CD5-positive DLBCL remain unknown. METHODS To identify molecular markers that can be targeted for treating DLBCL, a proteomic study was performed using liquid chromatography-mass spectrometry with chemically pretreated formalin-fixed paraffin-embedded specimens from CD5-positive (n = 5) and CD5-negative DLBCL patients (n = 6). RESULTS Twenty-one proteins showed significant downregulation in CD5-positive DLBCL compared to CD5-negative DLBCL. Principal component analysis of protein expression profiling in CD5-positive and CD5-negative DLBCL revealed that DNAJB1, DDX3X, and BTK, which is one of the B cell phenotypic proteins, were the most significantly downregulated proteins and served as biomarkers that distinguished both groups. Additionally, a set of immunoglobulins, including IgG4, exhibited significant downregulation. Immunohistochemistry analysis for BTK demonstrated reduced staining in CD5-positive DLBCL compared to CD5-negative DLBCL. CONCLUSIONS In conclusion, DNAJB1 and DDX3X, BTK, and a set of immunoglobulins are promising biomarkers. Probably, the suppression of BCR signaling is the unique phenotype of CD5-positive DLBCL. This formalin-fixed paraffin-embedded (FFPE)-based profiling may help to develop novel therapeutic molecularly targeted drugs for treating DLBCL.

Abstract
INTRODUCTION Static spine and pelvic posture has been reported to be associated with symptoms in patients with lumbar spinal stenosis (LSS), but it is unknown whether dynamic alignment of the spine and pelvis is associated with lumbar function in daily life. This study aims to investigate the relationship between dynamic alignment of the spine and pelvis during gait and lumbar function in daily life in patients with LSS. METHODS We evaluated lumbar function in daily life using the Oswestry Disability Index (ODI), trunk and hip muscle strength as physical function, static spinal alignment, and dynamic spinal/pelvic alignment during gait. The relationship between the ODI score and physical function or static and dynamic alignment was examined. RESULTS A total of 35 preoperative patients with LSS participated in this study. ODI score significantly correlated with trunk extension strength (r = -0.578, p = 0.000), hip extension strength (r = -0.472, p = 0.004), maximum spinal flexion angle during gait (r = -0.473, p = 0.004) and maximum pelvic anterior tilt angle (r = 0.510, p = 0.002). Multiple regression analysis showed that trunk extension strength (standardized β; - 0.309), hip extension strength (standardized β; -0.287), maximum spinal flexion angle (standardized β; - 0.306) and maximum pelvic anterior tilt angle (standardized β; 0.271) significantly affected the ODI score, with adjusted coefficient of determination of 0.529. CONCLUSION The results of this study showed that the patients with LSS with weak hip or trunk extensor muscles, a greater angle of pelvic tilt or a less spinal flexion during gait had a lower lumbar function in daily life.

Abstract
Osteoporotic vertebral fractures are recognized as a serious problem in the aging society. In this study, we found that the cumulated ambulation score predicts returning home in patients with osteoporotic vertebral fractures. The cumulated ambulation score is an important piece of information in determining the destination of patients with osteoporotic vertebral fractures. PURPOSE Osteoporotic vertebral fractures are a serious problem affecting the health status of the elderly, and if they require inpatient treatment, they may have difficulty deciding where to discharge. The study's purpose is to investigate whether the cumulated ambulation scores predict returning home for hospitalized osteoporotic vertebral fractures patients. METHODS The subjects were 120 osteoporotic vertebral fractures patients aged 65 years or older who were admitted to our hospital between April 2015 and March 2022. The cumulated ambulation scores for all subjects were measured in the 3-days right after admission. A multivariable analysis was performed with the dependent variable as whether the patient returned home and the independent variable as the cumulated ambulation score. Three models were created from the measured cumulated ambulation score, and each model was analyzed as an independent variable (model 1; score on the 1st day, model 2; total score on the 2-days, model 3; total score on the 3-days). RESULTS The length of hospitalization for the osteoporotic vertebral fracture's patients were 11.8 ± 5.3 days, and 80 (66.7%) returned home. Multivariable analysis showed that cumulated ambulation score was a predictor of returning home (model 1, odds ratio: 3.151, 95% confidence interval: 2.074-5.203; model 2, odds ratio: 2.234, 95% confidence interval: 1.685-3.187; model 3, odds ratio: 1.929, 95% confidence interval: 1.535-2.599). CONCLUSION The cumulated ambulation score of patients with osteoporotic vertebral fractures right after admission is a factor that affected returning home and is useful in determining where patients are discharged.

Abstract
PURPOSE The aim is to investigate whether a simple prone posture assessment test (P-test) at baseline can be predict the effectiveness of at least 3 months of physiotherapy for adults with structural spinal disorders. METHODS Seventy-six adults (age 71.0 ± 7.1 years) with structural spinal disorders who visited our outpatient clinic and underwent physiotherapy, which included muscle strength and range of motion training was provided once a week for a minimum of 3 months, and where the load was adjusted individually by the physiotherapist. The P-test is performed with the subject lying on the bed in a prone position and is positive if no low back pain is seen and the abdomen touches the bed. The Oswestry Disability Index (ODI) was used to assess disability. The minimum clinically important difference (MCID) was set at 10% improvement of the ODI score. Logistic regression analysis was performed to investigate the association between baseline P-test and achievement of ODI-MCID. RESULTS The study population characteristics were: Sagittal vertical axis 138.1 ± 73.2 mm; Pelvic tilt, 36.9 ± 9.8 degrees; Pelvic incidence minus lumbar lordosis, 45.3 ± 22.1 degrees; and maximum coronal Cobb angle, 21.3 ± 19.7 degrees. Logistic regression analysis showed that being positive on the P-test was associated with the achievement of ODI-MCID (Odds ratio, 8.381; 95% confidence interval, 2.487-35.257). CONCLUSIONS This study found that our developed P-test was a useful predictor of achieving the ODI-MCID in a cohort of adults with structural spinal disorders receiving at least 3 months of physiotherapy.

Abstract
PURPOSE The purpose of this study was to evaluate the gait posture of patients with adult spinal deformity (ASD) using a 3-dimensional motion analysis system (3DMAS) and to investigate whether it affects gait endurance. METHODS Fifty-one patients with ASD aged 50 years or older who were admitted to our hospital between March 2016 and March 2018 were included in the study. The subjects completed the 6-min walking test, which is an indicator of gait endurance. Static standing posture was assessed by whole-spine x-ray examination (coronal cobb angle, CCA; sagittal vertical axis, SVA; pelvic tilt, PT; and pelvic incidence minus lumbar lordosis, PI-LL). In addition, the gait posture was evaluated by a 3DMAS (dynamic trunk tilt angle, DTA; and dynamic pelvic tilt angle, DPA). The relationship between standing and gait postures and gait endurance was investigated by multivariable analysis. RESULTS In univariable analysis, SVA, PI-LL, and DTA were associated with gait endurance. Furthermore, in the multivariable analysis, DTA showed the strongest association among the static and dynamic parameters (R2 = 0.61, β = - 0.35, P < 0.05). CONCLUSIONS An association was found between gait posture and gait endurance in patients with ASD. These findings can be useful to health care providers treating patients with ASD. It is advisable to assess the gait posture of patients with ASD because they present postural abnormalities during gait.

Abstract
STUDY DESIGN This cross-sectional study was conducted in a single hospital. PURPOSE To clarify the relationship between lower limb pain intensity and dynamic lumbopelvic-hip alignment in patients with lumbar spinal canal stenosis (LSS), using a three-dimensional (3D) motion analysis system. OVERVIEW OF LITERATURE Although it is well known that leg symptoms have a close relationship with posture in patients with LSS, the relationship under dynamic conditions, such as gait, remain unclear. METHODS Thirty patients with LSS scheduled for spine surgery participated in this study. Lower limb pain was assessed using the Visual Analog Scale (VAS), and the patients were divided into two groups based on the mean scores (patients with scores above and below the mean were classified as the high-VAS and low-VAS groups, respectively). The kinematics of the spine, pelvis, and hip joints during gait were then measured using a 3D motion analysis system. Student paired t -tests were used to compare the angles of the spine, pelvis, and hip during gait between the two groups. RESULTS Compared to those in the low-VAS group, the spine was significantly extended and bent toward the more painful lower limb side, and the pelvis was significantly anteriorly tilted among individuals in the high-VAS group. CONCLUSIONS Patients with LSS experiencing severe pain in their lower limb tend to keep the spine in a more extended position, bend laterally toward the painful side, and have an anteriorly tilted pelvic posture. The dynamic spinal and pelvic alignment was closely related to the intensity of the lower limb pain.

Abstract
Study Design Single-hospital cross-sectional study. Purpose The aim of the present study was to investigate the physical functions influencing dynamic postural change in patients with adult spinal deformity (ASD). Overview of Literature Dynamic postural change leading to increased forward lean during gait is a problem in patients with ASD; however, the relationship between this change and trunk and hip extensor strength is unclear. Methods Thirty patients with ASD aged ≥50 years who were admitted to our hospital between July 2016 and September 2019 were included in this study. X-ray parameters (i.e., sagittal vertical axis, pelvic tilt, and pelvic incidence minus lumbar lordosis) were evaluated from the full-length standing radiographs of the subjects. Trunk and hip extensor strength was evaluated using a hand-held dynamometer. Dynamic postural changes (i.e., sagittal trunk shift during standing, sagittal trunk shift during gait, and delta sagittal trunk shift) were assessed using a three-dimensional motion analysis system. The relationships between dynamic postural change and various X-ray parameters, as well as trunk and hip extensor strength, were examined using multivariable analysis. Results Multivariable analysis showed that hip extensor strength is the factor most strongly associated with dynamic postural change among the X-ray parameters and physical functions assessed in this study (β=−0.41, R2=0.12). Conclusions We demonstrated the association between dynamic postural change and hip extensor strength in patients with ASD. Our results may be useful to healthcare providers treating patients with ASD. Interventions for dynamic postural change in patients with ASD should focus on hip extensor strength.

Abstract
AIM States of vulnerability are multidimensional and become more prevalent with advancing age. These states and the causal relationships between them, merit thorough investigation. This study aimed to understand the reciprocal relationship between the constructs of the locomotive syndrome and social frailty among a community of older adults. METHODS This 2-year cohort study examined a community of older adults (≥75 years) consisting of 1177 members. Using Makizako's method, social frailty was deemed to be present if more than two out of five questions were answered negatively. Locomotive syndrome was measured with the Geriatric Locomotive Function Scale-25, which consists of 25 items measuring an individual's risk of developing locomotive syndrome; a total score of ≥16 identified the presence of locomotive syndrome. Possible reciprocal associations between locomotive syndrome and social frailty were assessed using Cox proportional hazards analyses. RESULTS A total of 748 older adults were analyzed in the following subgroups. Among 574 participants without social frailty at the baseline, the presence of locomotive syndrome at the baseline was associated with new-onset social frailty during the next 2 years, after adjusting for confounding factors (hazard ratio 1.76, 95% confidence interval 1.17-2.65). Conversely, the presence of social frailty among participants without locomotive syndrome in the baseline was not associated with new-onset locomotive syndrome. CONCLUSION The presence of locomotive syndrome was determined to be a risk factor for the onset of social frailty. Therefore, interventions that address the negative impact of locomotive syndrome are a first step toward addressing these vulnerable conditions. Geriatr Gerontol Int 2021; 21: 981-984.

Abstract
Background:Recently, immunometabolism has gathered attention of many immunologists. It has been widely recognized that metabolic reprogramming in each immune cell brings different effects on different cells and is important for regulating their functions. Along with the progress of statistical genetics, serum metabolites were shown to be under genetic regulations1). Metabolic changes are now considered not only to be mere phenotypes of cells but also to be key factors for controlling immune cell differentiation, proliferation and function through regulating gene expressions eventually. Although genome-wide association studies have brought deep insights into SLE pathogenesis, the precise pathway from genome to metabolome has been largely unknown, and vice versa.Objectives:The aim of this study is to investigate metabolomic regulation in SLE in relation to gene expressions by integrating plasma metabolome data and transcriptome data.Methods:We collected plasma samples from patients with SLE (n=57) who met the 1997 American College of Rheumatology criteria for SLE. Gender- and age-matched healthy controls (HCs) (n=56) were recruited. Metabolic profiles focusing on 39 amino acids were analyzed with liquid chromatography (LC)-mass spectrometry. Transcriptome data of SLE patients were obtained from our RNA-sequencing data of each immune cell subset (total 19 subsets). Whole-genome sequencing was also performed.Results:Our previous experiment showed that about 160 peaks were detected from comprehensive LC-TOFMS and amino acids were useful for distinguishing SLE patients from HCs. Both partial least squares discriminant analysis (PLS-DA) and random forest, a machine learning algorithm, revealed the importance of histidine (His), one of the essential amino acids, to classify SLE patients from HCs, whose plasma level was lower in SLE patients. In addition, inverse correlation between His level and titer of ds-DNA as well as damage index (SDI) was detected. His level was correlated neither with PSL dosage nor with type I interferon (IFN) signature. Receiver operating characteristic (ROC) analysis showed the best predictability for SLE with the combination of specific amino acids including His. Our transcriptome analysis has revealed the significance of oxidative phosphorylation (OXPHOS) in B cells for SLE pathogenesis. Interestingly, OXPHOS signature was inversely correlated with His level in SLE B cells.Conclusion:His may be an important factor for SLE pathogenesis especially in B cells independently from IFN signal. SLC15A4, a transporter of His on lysosome, is one of the SLE GWAS SNPs and has been reported to play an important role in IFN production in B cells through regulation of TLR7/9 activation 2). We also identified that SLE patients with risk allele of SLC15A4 had tendency to show higher plasma His level, indicating His homeostasis could become a novel treatment target for SLE. Moreover, the inverse correlation of His level to SDI as well as OXPHOS signature suggests that His might play a key role for promoting organ damages in SLE.References:[1]Nat Genet.2017;49:568. 2)Immunity. 2014;41:375. 3)Semin Arthritis Rheum.2019;48:1142Disclosure of Interests: :Yukiko Iwasaki: None declared, Yusuke Takeshima: None declared, Masahiro Nakano: None declared, Mineto Ota: None declared, Yasuo Nagafuchi: None declared, Akari Suzuki: None declared, Yuta Kochi: None declared, Tomohisa Okamura: None declared, Takaho Endo: None declared, Ichiro Miki: None declared, Kazuhiro Sakurada: None declared, Kazuhiko Yamamoto Grant/research support from: Astellas, BMS, MitsubishiTanabe, Pfizer, Ayumi, Takeda, Chugai, Eisai, Taisho Toyama, UCB, and ImmunoFuture, Keishi Fujio Grant/research support from: Astellas, BMS, MitsubishiTanabe, Pfizer, Ayumi, Takeda, Chugai, Eisai, Taisho Toyama, Eli Lilly, Sanofi, and UCB

Abstract
OBJECTIVE Fetal fractional limb volume has been proposed as a useful measure for quantifying fetal soft tissue development. The aim of this study was to investigate the growth of fractional arm volume (AVol) and fractional thigh volume (TVol) of fetuses with maternal gestational diabetes (GDM) compared with those of fetuses with normal glucose tolerance (NGT). We hypothesised fetal fractional limb volume would be larger in the GDM group than in the NGT group in late gestation. DESIGN Exploratory observational study. SETTING Saitama Municipal Hospital. SAMPLE A total of 165 (125 NGT and 40 GDM) singleton Japanese pregnant women. METHODS AVol and TVol were assessed between 20 and 37 weeks' gestation as cylindrical limb volumes based on 50% of the fetal humeral or femoral diaphysis length. Women were diagnosed as GDM based on the criteria of the Japan Society of Obstetrics and Gynecology. MAIN OUTCOME MEASURES AVol and TVol were compared between women with NGT and those with GDM at each gestational age period (2-week intervals from 20 to 37 weeks' gestation). RESULTS Overall, 287 ultrasound scans were performed (NGT group, 205 scans; GDM group, 82 scans). There was no significant difference of AVol between the groups before 32 weeks' gestation. AVol was significantly larger in the GDM group than in the NGT group after 32 weeks' gestation (P < 0.05). TVol was not statistically different between the groups across gestation. CONCLUSIONS Detection of variations in fetal AVol may provide greater insight into understanding the origins of altered fetal body proportion in GDM. TWEETABLE ABSTRACT AVol, but not TVol, is significantly larger in fetuses with GDM than in those with NGT after 32 weeks' gestation.

Abstract
Abstract
Background
Irregular protrusion, a protrusion of material with an irregular surface into the lumen of the vessel after stent implantation, can only be identified by optical coherence tomography (OCT). A previous study demonstrated that irregular protrusion after stent implantation was an independent predictor of 1-year major adverse cardiac events (MACE) in CAD patients. However, the true incidence and prognostic significance of irregular protrusion after stenting in patients with ST-segment elevation myocardial infarction (STEMI) have not previously examined.
Aims
The aims of this study were the following: 1) to evaluate the incidence of irregular protrusion detected by OCT in STEMI patients after stenting; and 2) to compare the long-term outcomes between patients with and without irregular protrusion.
Methods and results
A total of 210 STEMI patients who had post-procedure OCT imaging after coronary stenting within 12 hours after symptom onset were studied. We divided them into two groups: those with irregular protrusion (n=159) and those without (n=51) after stenting. There were no significant differences in baseline characteristics between the 2 groups except that peak CK-MB levels were higher in patients with irregular protrusion than those without (289 (137–563) vs. 260 (63–349) U/L, p<0.05). During mean follow-up period of 298 days, the overall incidence of MACE defined as cardiac death, target vessel-related myocardial infarction, and target lesion revascularization was 15.3%. Kaplan-Meier curve showed that the incidence of MACE did not differ between patients with and without irregular protrusion (14.7% vs. 17.7%, p=0.53 by Log-rank).
Conclusions
Irregular protrusion after stent implantation was detected in three-fourth of STEMI patients. Although patients with irregular protrusion had a greater myocardial damage, it did not influence clinical outcomes.

Abstract
Abstract
Background
In the VAMPIRE 3 (VAcuuM asPIration thrombus REemoval 3) trial, we have previously shown that selective use of distal filter protection during percutaneous coronary intervention (PCI) decreased the incidence of no-reflow phenomenon and was associated with fewer in-hospital serious adverse cardiac events than conventional PCI in patients with attenuated plaque ≥5mm. However, whether the early efficacy of distal embolic protection translate into long term clinical benefit is unknown.
Methods
Patients with acute coronary syndrome (ACS) with attenuated plaque ≥5mm were assigned to distal protection (DP) (n=98) or conventional treatment (CT) (n=96). The primary end point of the incidence of no-reflow phenomenon during PCI and the secondary end point of in-hospital serious adverse cardiac events has been reported previously. The rate of a major adverse events, a composite of death from any cause, non-fatal myocardial infarction, or unplanned target vessel revascularization (TVR) at 1 year was the prespecified secondary end point of the trial. All clinical endpoint events were adjudicated by an independent Clinical Event Committee.
Results
Major adverse events at 1 year occurred in 12 patients (12.2%) in the DP group and in 3 patients (3.1%) in the CT group (P=0.029). The difference was driven by a higher risk of TVR (11 [11.2%] vs. 2 [2.1%], p=0.018) in the DP group compared with the CT group. In patients treated with bare metal stents (n=42), major adverse events occurred in 25.0% of the patients in the DP group and in none of the patients in the CT group (P=0.029), whereas in patients treated with drug eluting stents (n=152), rates of major adverse events were similar between the groups (8.1% vs. 3.9%, p=0.32). Rates of cardiac death were not significantly different (1.0% vs. 1.0%, p=1.00). No definite stent thrombosis was observed in either group.
Conclusions
In the VAMPIRE 3 trial of patients with ACS with attenuated plaque ≥5mm, the 1-year rates of major adverse events in the distal protection group were higher than in the conventional treatment group. This effect could be mitigated by the use of drug eluting stents.

Abstract
OBJECTIVES Coexistence of chronic musculoskeletal pain and depressive symptoms is common, and their combined effect on adverse events warrants investigation. The purpose of this study was to investigate the individual and combined effect of chronic musculoskeletal pain and depressive symptoms on the onset of disability, which is a crucial outcome in older adults. DESIGN A 1-year cohort study. SETTING AND PARTICIPANTS 1251 community-dwelling older adults. MEASUREMENTS The number of chronic musculoskeletal pain sites was measured using a self-reported questionnaire. Depressive symptoms were assessed using the Geriatric Depression Scale-15. Disability was self-reported as any difficulty in basic activities of daily living. Incidence of disability was defined as any difficulty in performing 1 or more tasks at the follow-up assessment, that was absent at baseline. RESULTS Older adults with more chronic musculoskeletal pain sites tend to have depressive symptoms at baseline (P for trend < .001). Compared to older adults without both chronic musculoskeletal pain and depressive symptoms, older adults with both chronic multisite musculoskeletal pain and depressive symptoms have the higher risk for development of disability (adjusted odds ratio: 6.84, 95% confidence interval: 3.72 to 12.58), followed by older adults with chronic multisite musculoskeletal pain and without depressive symptoms (adjusted odds ratio: 2.13, 95% confidence interval: 1.35 to 3.37). CONCLUSIONS/IMPLICATIONS Simultaneous assessment of both chronic musculoskeletal pain and depressive symptoms may be useful for accurate prognosis and preventing disability in older adults.

Abstract
BACKGROUND Although percutaneous endoscopic gastrostomy (PEG) is a well-accepted and less invasive method of feeding tube placement in patients with swallowing difficulties, complications and early death after PEG have been reported. AIM This study aimed to evaluate predictive factors associated with 30-day mortality after PEG, and to assess the utility of nutritional supporting period before PEG in reducing early mortality following PEG. DESIGN An observational study. METHODS We retrospectively analyzed 268 patients who underwent PEG at Sapporo Shirakaba-dai Hospital from 2006 to 2010, using clinical and laboratory data to analyze predictive factors associated with early death after PEG. Then, we prospectively assessed 152 consecutive patients assessed for eligibility for PEG from 2011 to 2014. We assessed the patients' nutritional condition using Onodera's prognostic nutritional index (PNI), and supported nutrition for more than 10 days before PEG in patients with a poor nutritional index (PNI < 37). RESULTS In both univariate and multivariate analyses in the retrospective study, Onodera's PNI of less than 37 was the only predictive factor for early mortality. In the second study, among the 115 patients who finally underwent PEG, early mortality rates improved to 1.7% from 5.2% in the first study. Conversely, 32% of patients with malnutrition who did not undergo PEG died within 30 days. CONCLUSION Nutritional status might be a predictive factor for early mortality after PEG. In patients with poor nutritional status, nutritional supporting period before PEG might improve the outcomes and reduce unnecessary PEG.

Abstract
High molecular weight neutrophil chemotactic activity has been identified in resected human nasal polyps, inferior turbinates, and nasal secretions following antigen challenge. The estimated molecular weight, by gel filtration chromatography, was approximately 600,000. However, a heterogeneity of molecular weight in some patients was recognized. Our results suggest a possible role for high molecular weight-neutrophil chemotactic activity in the pathogenesis of hypersensitivity in the human nasal cavity.

Abstract
Poly(sodium styrenesulfonate)⁻block⁻poly(acrylic acid) (PNaSS⁻b⁻PAA) and poly(sodium styrenesulfonate)⁻block⁻poly(N-isopropylacrylamide) (PNaSS⁻b⁻PNIPAM) were prepared via reversible addition⁻fragmentation chain transfer (RAFT) radical polymerization using a PNaSS-based macro-chain transfer agent. The molecular weight distributions (Mw/Mn) of PNaSS⁻b⁻PAA and PNaSS⁻b⁻PNIPAM were 1.18 and 1.39, respectively, suggesting that these polymers have controlled structures. When aqueous solutions of PNaSS⁻b⁻PAA and PNaSS⁻b⁻PNIPAM were mixed under acidic conditions, water-soluble PNaSS⁻b⁻PAA/PNaSS⁻b⁻PNIPAM complexes were formed as a result of hydrogen bonding interactions between the pendant carboxylic acids in the PAA block and the pendant amide groups in the PNIPAM block. The complex was characterized by ¹H NMR, dynamic light scattering, static light scattering, and transmission electron microscope measurements. The light scattering intensity of the complex depended on the mixing ratio of PNaSS⁻b⁻PAA and PNaSS⁻b⁻PNIPAM. When the molar ratio of the N-isopropylacrylamide (NIPAM) and acrylic acid (AA) units was near unity, the light scattering intensity reached a maximum, indicating stoichiometric complex formation. The complex dissociated at a pH higher than 4.0 because the hydrogen bonding interactions disappeared due to deprotonation of the pendant carboxylic acids in the PAA block.

Abstract
Abstract
Background:
Tumor angiogenesis and hypoxia are associated with breast cancer growth and metastasis. Photoacoustic (PA) tomography is an optical imaging technology that visualizes distribution and oxygenation status of hemoglobin with high spatial resolution. Initially we developed a photoacoustic mammography (PAM) having a flat-shaped scanning detector that could detect breast tumors. Nevertheless, the flat-shaped detector array has the drawback of a limited view. Here we developed a novel PAM system with a hemispherical-shaped detector array (HDA), which enables us to identify microvasculatures non-invasively and allow the collection of nearly spatially isotropic three-dimensional reconstructed image of blood vessels. This non-invasive vascular imaging system may be able to characterize tumor angiogenesis and analyze the status of microcirculation. The aim of this study was to analyze the imaging findings of tumor-related vasculature in breast cancer patients.
Patients and method:
A PAM system with HDA has been generated in a cooperation project between Canon Inc., Japan, and Kyoto University. Twenty-two primary breast cancer patients, including 5 patients with non-invasive cancer and 17 patients with invasive cancer, diagnosed between December 2014 and December 2015 underwent the PAM imaging analysis. We also applied the breast deformation algorithm from the breast shape in a MRI image to that in a PA image in order to create a fusion image of the two modalities for the analysis. Features of peri- and intra-tumoral vasculature, and their oxygenation status were evaluated. The study protocol was approved by the institutional review board at Kyoto University Hospital (UMIN000012251). All patients provided informed consent to participate in this study.
Results:
The abnormal peri-tumoral vasculature was detected in 86% of all non-invasive and invasive disease cases. In invasive cancer cases, most tumor-related blood vessels were centripetally directed toward the tumor, and 93% of centripetal blood vessels appeared to be disrupted or rapidly narrowed at the tumor boundary. The centripetal blood vessel structure was frequently observed in invasive cancer compared with non-invasive cancer (61% vs 35%). PA images before and after preoperative chemotherapy were obtained in one case, where intra-tumoral blood vessels became finer after chemotherapy, reflecting normalization of intra-tumoral microcirculation induced by chemotherapy.
Conclusions:
A PAM system with HDA has provided a high-resolution vascular images of primary breast cancers. The morphological differences of peri-tumoral vasculature were observed between invasive disease and non-invasive disease. These results suggest the potential of PA imaging as a non-invasive tool to analyze tumor vasculature of human breast cancers and maybe be helpful for breast cancer diagnosis.

Abstract
Noninvasive measurement of the distribution and oxygenation state of hemoglobin (Hb) inside the tissue is strongly required to analyze the tumor-associated vasculatures. We developed a photoacoustic imaging (PAI) system with a hemispherical-shaped detector array (HDA). Here, we show that PAI system with HDA revealed finer vasculature, more detailed blood-vessel branching structures, and more detailed morphological vessel characteristics compared with MRI by the use of breast shape deformation of MRI to PAI and their fused image. Morphologically abnormal peritumoral blood vessel features, including centripetal photoacoustic signals and disruption or narrowing of vessel signals, were observed and intratumoral signals were detected by PAI in breast cancer tissues as a result of the clinical study of 22 malignant cases. Interestingly, it was also possible to analyze anticancer treatment-driven changes in vascular morphological features and function, such as improvement of intratumoral blood perfusion and relevant changes in intravascular hemoglobin saturation of oxygen. This clinical study indicated that PAI appears to be a promising tool for noninvasive analysis of human blood vessels and may contribute to improve cancer diagnosis.

Abstract
BACKGROUND & AIMS The δ13C and δ15N values in the scalp hair of geriatric patients in Japan who received the enteral or parenteral nutrition formula were measured to assess nutritional status. METHODS The relations among δ13C, δ15N, calorie intake, BMI, albumin concentration, total cholesterol (T-CHO) and geriatric nutritional risk index (GNRI) in the patients were investigated. Furthermore, the enrichment of δ13C and δ15N from the nutrients to the hair was investigated. RESULTS The δ13C values in the hair of patients who received enteral nutrition decreased with decreases in the calories received, while the δ15N values increased, suggesting malnutrition in some patients with a low calorie intake due to a negative nitrogen balance. The distribution of patients with a low calorie intake (below 20 kcal/kg/day) when δ13C was plotted against δ15N differed from that of control subjects, but the distribution of patients with a high calorie intake (above 20 kcal/kg/day) was similar to that of control subjects. No significant differences were observed in BMI, albumin concentration, T-CHO or GNRI between the low and high calorie groups. The enrichment of δ13C and δ15N from the enteral nutrients to the hair were inversely correlated with the δ13C and δ15N in the enteral nutrients. The enrichment levels of δ13C and δ15N tended to be higher and lower, respectively, in the high calorie group. On the other hand, the δ13C and δ15N values in the hair of patients who received parenteral nutrition were higher and lower than those in the control subjects and in the patients who received enteral nutrition, respectively, reflecting the higher δ13C and lower δ15N contents of the parenteral nutrients. CONCLUSIONS The δ13C and δ15N values in the hair of patients who received enteral nutrition may be effective indicators for evaluating the long-term nutritional status of geriatric patients. A calorie intake of 20 kcal/kg/day may be a cut-off value for malnutrition in Japanese geriatric patients receiving enteral nutrition. However, caution is necessary when dealing with patients switching from parental nutrition as parenteral nutrition resulted in different changes in δ13C and δ15N. The enrichment levels of δ13C and δ15N from the enteral nutrients to the hair may be inversely correlated with the δ13C and δ15N values of enteral nutrients and vary according to the calorie intake.

Abstract
BACKGROUND HECT domain and ankyrin repeat containing E3 ubiquitin protein ligase 1 (HACE1) regulates a wide variety of cellular processes. It has been shown that one of the targets of HACE1 is the GTP-bound form of the small GTPase Rac1. However, the role of HACE1 in early development remains unknown. RESULTS In situ hybridization revealed that Xenopus laevis hace1 is specifically expressed in the ectoderm at the blastula and gastrula stages and in the epidermis, branchial arch, kidney, and central nervous system at the tailbud stage. Knockdown of hace1 in Xenopus laevis embryos via antisense morpholino oligonucleotides led to defects in body axis elongation, pigment formation, and eye formation at the tadpole stage. Experiments with Keller sandwich explants showed that hace1 knockdown inhibited convergent extension, a morphogenetic movement known to be crucial for body axis elongation. In addition, time lapse imaging of whole embryos during the neurula stage indicated that hace1 knockdown also delayed neural tube closure. The defects caused by hace1 knockdown were partly rescued by knockdown of rac1. Moreover, embryos expressing a constitutively active form of Rac1 displayed phenotypes similar to those of embryos with hace1 knocked down. CONCLUSIONS Our results suggest that Xenopus laevis hace1 plays an important role in early embryonic development, possibly via regulation of Rac1 activity.

Abstract
To realize a novel vacuum-atmosphere interface that does not require a large differential pumping system, a robust cascade arc discharge source called a plasma window is constructed and tested for long-term operation. By modifying a test plasma with a direct current discharge, a vacuum interface with a high gas pressure ratio of 1/407 between the discharge and expansion sections is demonstrated for currents as high as 20 A. No significant damage to the electrodes is observed during the operation. Analysis of the visible emission spectra reveals that a stationary, stable argon plasma having a temperature of 1 eV and a density of 1.5 × 10(16) cm(-3) is generated in the plasma channel.

Abstract
The hippocampal sulcus remnant (HSR) is often observed at the medial temporal lobe on MR images. In the present study, we made a retrospective assessment of the frequency and age-related differences in HSR in routine brain MR examinations of 1000 patients, 494 females and 506 males. Cases with one or several spots that were hypointense on T1-weighted and FLAIR images and hyperintense on T2-weighted images were defined as positive for HSR. Abnormal spots with the same intensity as cerebrospinal fluid were observed in 210 out of 506 males and in 193 out of 494 females. No significant sex-related differences were observed in the frequency of HSR. The HSR was seen more frequently with age in both males and females. Patients with hypertension had a significantly higher frequency of HSR.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
Architectural distortion is one of the most important findings when evaluating mammograms for breast cancer. Abnormal breast architecture is characterized by the presence of spicules, which are distorted mammary structures that are not accompanied by an increased density or mass. We have been developing an automated method for detecting spiculated architectural distortions by analyzing linear structures extracted by normal curvature. However, some structures that are possibly related to distorted areas are not extracted using this method. The purpose of this study was to develop a new automated method for direction analysis of linear structures to improve detection performance in mammography. The direction of linear structures in each region of interest (ROI) was first determined using a direction filter and a background filter that can define one of eight directions (0°, 22.5°, 45°, 67.5°, 90°, 112.5°, 135°, and 157.5°). The concentration and isotropic indexes were calculated using the determined direction of the linear structures in order to extract the candidate areas. Discriminant analysis was performed to eliminate false positives results. Our database consisted of 168 abnormal images containing 174 distorted areas and 580 normal images. The sensitivity of the new method was 81%. There were 2.6 and 4.2 false positives per image using the new and previous methods, respectively. These findings show that our new method is effective for detecting spiculated architectural distortions.

Abstract
BACKGROUND Pre-emptive therapy with valganciclovir (VGCV) has become the standard therapy for preventing cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (HSCT). The effectiveness of low-dose VGCV (900 mg per day) has been shown to be equal to that of standard-dose VGCV (900 mg twice daily); however, individualized optimal dosing and toxicity of VGCV have not been reported. METHODS We conducted a retrospective study to evaluate the optimal dose of VGCV as pre-emptive therapy for preventing CMV infection by comparing the frequency of adverse events (AEs) and clinical efficacy in a low-dose VGCV group with those in a standard-dose VGCV group. Thirty-eight patients who were administered VGCV because of CMV antigenemia after HSCT were analyzed. RESULTS Neutropenia (standard-dose group: 33%, low-dose group: 15%, P = 0.26) and thrombocytopenia (standard-dose group: 39%, low-dose group: 15%, P = 0.14) were frequent AEs of VGCV, and a significantly higher frequency of overall AEs was detected in the standard-dose group than in the low-dose group (P < 0.01). In comparison of dosage based on weight, dosage of VGCV >27 mg/kg was closely related to onset of AEs (P = 0.04). CONCLUSIONS Low-dose VGCV was not inferior in clinical efficacy, including clearance rate of CMV antigenemia and incidence of consequent CMV disease, to standard-dose VGCV as was previously reported. Initial low-dose VGCV for pre-emptive CMV therapy markedly reduces hematologic toxicity and has clinical efficacy equivalent to that of standard-dose VGCV. It is therefore reasonable for patients, except for noticeably overweight patients, to be given initial low-dose VGCV.

Abstract
Although chemical trapping has been widely used to evaluate cytochrome P450-mediated drug bioactivation, thus far, only a few in vitro-trapping studies have been performed on UDP-glucuronosyltransferase (UGT)-mediated drug bioactivation. In this study, we used cysteine (Cys) as trapping agent to gain new insights into the UGT-mediated bioactivation involving acyl glucuronides of carboxylic acid drugs. Diclofenac, ketoprofen and ibuprofen were incubated in human liver microsomes with UDPGA and Cys, followed by analysis using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). The N-acyl-Cys amide adduct of diclofenac was characterized by mass analysis and was detectable even in photodiode array analysis. Our data indicated that the formation of such adducts reflects the reactivity of the corresponding acyl glucuronides. In addition, it was suggested that the adduct formation requires an N-terminal Cys moiety with both a free amine and a free thiol group, from the results using various cysteine derivatives. We propose that the S-acyl-Cys thioester adduct can form via transacylation of an acyl glucuronide and can then form to an N-acyl-Cys amide adduct through intramolecular S- to N-acyl rearrangement. This series of the reactions has important implications as a possible bioactivation mechanism for covalent binding of carboxylic acid drugs to macromolecules.
