Abstract
PURPOSE/OBJECTIVE(S) The purpose of this study was to develop on a new bolus (HM bolus) which had tissue equivalence, transparency, reusability, and free shaping at approximately 40°C for excellent adhesion, and to evaluate its features could be satisfy ideal bolus conditions for clinical use. MATERIALS/METHODS The newly developed HM bolus was controlled to prevent phase separation by adjusting the contents of ethylene propylene rubber, styrene, butadiene rubber, thermoplastic resin, temperature-sensitive adjuster, and silica. The element ratios (wt%) in the HM bolus are H: 10.2%, C: 63.5%, O: 17.1%, and Si: 9.2%. The density was adjusted to 0.96 g cm-3. We evaluated dose characteristics, a vinyl gel sheet bolus (Gel bolus) and HM bolus placed on a water-equivalent phantom were used to obtain the percent depth dose (PDD) of electron (6 MeV, 9 MeV) and photon (4 MV,6 MV) beams. The average dose difference of the HM bolus and Gel bolus was calculated. The Gel bolus, a soft rubber bolus (SR bolus), and HM bolus were placed in adherence to a pelvic phantom. CT images taken after shaping and 1, 2, and 3 weeks after shaping were used to evaluate the adhesion and reproducibility using air gap and dice similarity coefficient (DSC) metrics. The visibility of letters (maximum: 80 pt, minimum: 10 pt) through a plate-shaped bolus and the visibility of markers when each bolus was set up on the pelvic phantom under normal room lighting were evaluated. RESULTS The average dose difference for electron beams was 0.16% ± 0.79% and photon beams was 0.06% ± 0.34%, both within 1% of the PDD results. The HM bolus showed the same build-up effect and dose characteristics as the Gel bolus. The mean air gap values for the Gel bolus, SR bolus, and HM bolus were 96.02 ± 43.77 cm3, 34.93 ± 21.44 cm3, and 4.40 ± 1.50 cm3 44, respectively. The mean DSC values for the Gel bolus, SR bolus, and HM bolus were 0.363 ± 0.035, 0.556 ± 0.042, and 0.837±0.018. The HM bolus showed the smallest air gap at all time points and the DSC closest to 1. Excellent adhesion was observed in the CT simulation and during the treatment period. The letter visibility through the HM bolus and Gel bolus was sufficient, and when the HM bolus was set up on the pelvic phantom, the markers that were completely invisible with the SR bolus were visible. CONCLUSION We succeeded in developing an all-purpose bolus with unique characteristics for clinical use. The HM bolus had the same build-up effect and dose characteristics as a Gel bolus. Therefore, it can be used for CT simulation and dose calculation. The other advantages of the new bolus are tissue equivalence, transparency, reusability, and free shaping at approximately 40°C, providing excellent adhesion at each setup during the treatment period.

Abstract
INTRODUCTION AND IMPORTANCE Although corticosteroids are effective for bronchial asthma, they are associated with various side effects, such as osteonecrosis of the femoral head and tibial condyle and osteoporosis. Here, we report a patient who was on corticosteroids for a long period of time due to severe asthma, which was thought to have led to lunate osteonecrosis of both wrist joints. Calcitonin (elcatonin), an osteoporosis drug, was administered to the wrist joint. CASE PRESENTATION Allergy to anesthetics and various non-steroidal anti-inflammatory drugs (NSAIDs) made surgical treatment not possible and pain control difficult. In addition, pain in the wrist joint interfered with activities of daily living (ADLs). When calcitonin was administered intra-articularly into the wrist joint, the pain in the wrist joint was relieved and ADLs were improved. However, the pain-suppressing effect lasted only 1 week, and pain returned to the original state by the second week after treatment. Repeated injections were necessary every 2 weeks. CLINICAL DISCUSSION This is the first report of the effectiveness of intra-articular calcitonin in a patient with osteonecrosis of the lunate. This treatment may be applicable to patients with allergies to anesthesia and NSAIDs. CONCLUSION In the present case, calcitonin administered intra-articularly to the wrist appeared to be effective in pain control for steroid-induced lunate osteonecrosis.

Abstract
Background: Carpal tunnel syndrome is occasionally associated with basal joint arthritis and is more common in postmenopausal women than in the general population. Currently, more evidence is needed to describe changes in the carpal tunnel after basal joint arthroplasty (BJA) of the thumb and to determine whether it is better to combine the release of the flexor retinaculum. The purpose of this study was to clarify the changes in the carpal tunnel cross-sectional area and carpal tunnel shape after complete removal of the trapezium during BJA of the thumb, according to computed tomography (CT) findings. Methods: We retrospectively investigated the carpal tunnel cross-sectional area with CT findings obtained pre- and postoperatively in 20 postmenopausal women who underwent BJA of the thumb. Results: The average horizontal plane area of the carpal tunnel was 1.11 ± 0.19 cm2 preoperatively and increased to 1.23 ± 0.2 cm2 at 3 months postoperatively (p = 0.0411). The ratio of the longitudinal diameter to the horizontal diameter was significantly increased from 0.6 ± 0.13 preoperatively to 1.23 ± 0.2 postoperatively (p = 0.0439). Conclusions: The increase in the carpal tunnel cross-sectional area was confirmed after BJA of the thumb. This increased carpal tunnel cross-sectional area changed as the longitudinal diameter increased, without changes in the horizontal diameter. Level of Evidence: Level IV (Therapeutic).

Abstract
BackgroundAchievement of normal physical function is an important outcome for older patients. Previous studies of younger cohorts showed that aging, comorbidities, and joint damage influenced the physical function of patients with RA who achieved clinical remission or low disease activity (LDA). We previously demonstrated that a treat-to-target (T2T) strategy for methotrexate (MTX)-naïve elderly-onset RA (EORA) was effective with an acceptable safety profile. It showed that 60.9% of 197 patients achieved HAQ Disability Index (HAQ-DI) ≤0.5 at three years by following the T2T strategy targeting LDA (1).ObjectivesWe aimed to evaluate associated factors with HAQ-DI in the T2T strategy targeting LDA for patients with EORA during three-year observational period.MethodsTreatment was adjusted to target LDA with conventional synthetic disease-modifying antirheumatic drugs (DMARDs), followed by biological DMARDs (bDMARDs) in 197 MTX-naïve EORA patients (mean age 74.9 years) with moderate-to-high disease activity. HAQ-DI was evaluated at week 0, 24, 52, 76, 104, 128, and 156. To evaluate associated factors with SDAI and HAQ-DI over the 36-month follow-up, Bayesian hierarchical logistic regression modeling was applied for 1067 periods from the 197 patients.ResultsAt baseline, the enrolled 197 patients with EORA who had normal physical function (HAQ-DI ≤0.5) in 29.4%, HAQ-DI >0.5 and <1.5 in 36.5%, and HAQ-DI ≥1.5 in 33.0%, and the mean age (standard deviation [SD]) in each group was 72.7 (5.9), 74.8 (7.3), and 75.6 (6.7), respectively. Baseline SDAI increased in the group with higher HAQ-DI. The proportions of patients with each comorbidity and estimated creatinine clearance at baseline were not significantly different across the 3 groups.In the multilevel logistic model, the association of MTX, bDMARDs, and GC use with changes in SDAI in each period was evaluated. Age, sex, and comorbidities (chronic lung disease, cardiovascular disease, history of malignancy, osteoporosis, history of serious infections, and osteoarthritis) were included as inter-individual factors. The model indicated that the use of bDMARDs was associated with a reduction of the SDAI (ΔSDAI: -9.75, SD 0.75, p<0.001), while neither MTX (ΔSDAI: -1.25, SD 1.13, p=0.270) nor GCs (ΔSDAI: -0.78, SD 0.88, p=0.372) was associated with changes in SDAI. Chronic lung diseases (ΔSDAI: 4.64, SD 1.44, p=0.001) and osteoporosis (ΔSDAI: 3.78, SD 1.46, p=0.001) at baseline were associated with the increment of SDAI.The association of age, sex, the comorbidities, and MTX, bDMARDs, and GC use with physical function in each period was evaluated by the multilevel logistic model. The model indicated that older age (ΔHAQ-DI: 0.03, SD 0.01, p <0.001), chronic lung diseases (ΔHAQ-DI: 0.15, SD 0.10, p=0.001), and osteoporosis (ΔHAQ-DI: 0.30, SD 0.10, p=0.010) at baseline were associated with the increment of HAQ-DI. When the mean SDAI during the observation period was added to the model as an inter-individual factor, the associations of HAQ-DI with the chronic lung diseases and osteoporosis at baseline were not statistically significant.ConclusionThese data indicate that bDMARDs had a central role in reducing disease activity in the T2T strategy targeting LDA in EORA patients. Chronic lung diseases and osteoporosis at baseline were associated with increase in disease activity and worsening of physical function. However, disease activity had a greater impact on physical function than the comorbidities at baseline.References[1]Sugihara T, et al.

Abstract
Introduction: Although there are few descriptions in textbooks and it is stated that the treatment of metaphyseal–diaphyseal junctional (MDJ) fracture is difficult, there is almost no detailed description on its treatment methods and precautions. Case Presentation: We encountered two patients, 9-year-old and 1-year and 11-month-old Japanese boys, with MDJ fractures of the distal humerus, which are very rare in children. Unlike supracondylar fractures of the distal humerus, the fractures were spiral fractures, which made percutaneous pinning very difficult. Open reduction was performed using a bilateral approach with two skin incisions. Both patients recovered completely and had no problems carrying out activities of daily living or playing sports. Conclusions: For patients that are old enough to receive a locking plate, we recommend fixation using a locking plate. In cases of unilateral pinning without cross-pinning, retrograde intramedullary nailing should be considered. MDJ fractures of the distal humerus should be treated as distal humeral shaft fractures, not as subtypes of supracondylar fractures of the humerus.

Abstract
Carpal tunnel syndrome (CTS) is a disorder that affects the median nerve at the wrist sufficient to cause impairment of nerve function. Elevated carpal tunnel pressure (CTP) leads to median nerve pathology, sensory, and motor changes in CTS patient. The techniques to quantify CTP used in clinic are invasive. This study aimed to investigate the feasibility of a noninvasive ultrasound vibro-elastography (UVE) to predict CTP in CTS patients and healthy individuals. The magnitudes of shear wave speed ratio (rSWS) of the 10 CTS patients (10 hands) and 6 healthy individuals (12 hands), and 10 cadaveric hands were compared using UVE. The ratios of intra to extra-carpal tunnel SWS in CTS patients was significantly higher than those in the healthy individuals (p = 0.0008) and cadaveric hands (p = 0.0015) with 500-g tendon tension. We estimated the CTP in the carpal tunnel using the mean rSWS of each group obtained from the present study and the linear approximation obtain from cadaveric hands data with 500-g tendon tension (y = 0.0036x + 1.1413). These results indicated that the elevated pressure applied to the 3rd flexor digitorum superficialis tendon in the carpal tunnel of CTS patients resulted in faster shear wave propagation. These results show that UVE was useful to indirectly estimate the CTP by measuring the rSWS; thus, they are potentially useful for the early diagnosis and assessment of CTS.

Abstract
BACKGROUND Concern regarding the benefit/risk ratio of the long-term use of benzodiazepines (BDZs) and Z-drugs is increasing. To prevent the risk of dependence in BDZ long-term use, it is essential to understand the attitudes of patients and psychiatrists toward BDZ treatment. The aims of this investigation were to 1) obtain information on patients' attitudes with long-term BDZ use and their referring psychiatrists' attitudes toward BDZ treatment, including their perception of the difficulty of reducing the dose of BDZs, and 2) identify discrepancies between patients' and psychiatrists' perceptions. METHODS A brief questionnaire was constructed to investigate the attitudes of patients receiving BDZ treatment and their referring psychiatrists. Our sample comprised 155 patients who received BDZ treatment for more than one year and their referring eight psychiatrists. Both the patients and their psychiatrists completed our questionnaire between August 2017 and December 2017. RESULTS Of the patients, 13% felt that it was more difficult to reduce the dose of BDZs than their referring psychiatrists (type A discrepancy), while 25% felt that it was less difficult (type B discrepancy). In the multivariate logistic regression analysis, the female sex and both the patients' ("psychotherapy plus BDZs was necessary" and "it was necessary to increase the dose of BDZs") and psychiatrists' beliefs ("short-term prescription was justified") were associated with type A discrepancies. Type B discrepancies were associated with psychiatrists' beliefs that the patient's wishes justified the use of BDZs and that the cessation of treatment with BDZs would lead to the deterioration of their rapport with their patients. CONCLUSION To overcome the discrepancies in the attitudes of patients and psychiatrists toward the cessation of BDZ treatment, it is necessary to promote patient-centered care involving patient psychoeducation and practice guidelines for the decision-making process. Further studies investigating the promotion of patient-centered care to reduce BDZ use are needed.

Abstract
Background Scaphoid nonunion with humpback deformity and avascular necrosis (AVN) is a challenging problem. Correction of dorsal intercalated segment instability (DISI) requires grafting of a large and hard vascularized bone segment onto the volar side of the scaphoid. Purposes We have been treating the patients with one-incision vascularized bone grafting technique for scaphoid nonunion to improve blood supply and correct humpback deformity. We evaluated these cases retrospectively to the surgical efficacy of our procedure. Methods We harvested vascularized bone from the dorsal side of the radius using the method by Zaidemberg et al and inserted the cortical aspect into the scaphoid volar side using a direct lateral approach. Totally, 11 patients (nine males andtwo females) with a mean age of 40 years were recruited for this study. The mean time from fracture to treatment was 6 years and 3 months. The mean preoperative radiolunate angle was 25 degrees. All the patients showed AVN of the proximal scaphoid on T1-weighted images. An averaged follow-up period was 2 years and 3 months. Results Postoperative computed tomography revealed bony union in 10 patients (91% of union rate) with a mean modified Mayo'swrist score of 88 points (range, 75-100 points) and a mean disabilities of arm, shoulder, and hand (DASH) score of 4 points (range, 0-20 points). The mean radiolunate angle was corrected from 25 to 5 degrees. No adverse events were observed, except temporary mild paresthesia of the radial nerve territory in two patients. Conclusion This technique effectively corrected DISI in patients with scaphoid nonunion accompanied by humpback deformity and AVN.

Abstract
Objective The objective of this study was to investigate possible differences in
treatment responses between two categories for the onset of lupus
nephritis. Methods We performed a multicentre, retrospective cohort study of class III–V lupus
nephritis patients diagnosed between 1997 and 2014. The renal responses to
initial induction therapy were compared between patients who developed lupus
nephritis within one year from diagnosis of systemic lupus erythematosus
(early (E-) LN) and the remainder (delayed (D-) LN) using the Kaplan–Meier
method. We determined the predictors of renal response as well as renal
flares and long-term renal outcomes using multivariate Cox regression
analyses. Results A total of 107 E-LN and 70 D-LN patients were followed up for a median of
10.2 years. Log-rank tests showed a lower cumulative incidence of complete
response in D-LN compared with E-LN patients. Multivariate analysis
identified D-LN (hazard ratio (HR) 0.48, 95% confidence interval (CI)
0.33–0.70), nephrotic syndrome at baseline, and a chronicity index greater
than 2 as negative predictors of complete response. D-LN patients were more
likely to experience renal flares. D-LN (HR 2.54, 95% CI 1.10–5.83) and
decreased renal function were significant predictors of chronic kidney
disease at baseline. Conclusion D-LN was a predictor of poorer treatment outcomes, in addition to renal
histology and severity of nephritis at lupus nephritis onset.

Abstract
Some patients with insulinoma present with neuropsychiatric symptoms and are often misdiagnosed with psychiatric disease. We present the case of a 72-year-old Japanese female who exhibited violent behavior while asleep and received a diagnosis of suspected rapid eye movement sleep behavior disorder (RBD). She was admitted to the psychiatry ward after receiving levomepromazine 25 mg intramuscularly. The patient’s blood glucose level was 27 mg/dL at the time of hospitalization, and a biochemical examination revealed that her insulin level was 9.1 µU/mL and C-peptide level was 2.16 ng/mL. A contrast-enhanced computed tomography revealed a mass 8 mm in diameter in the pancreatic head. The diagnosis was changed from RBD to insulinoma. The sleep behavior disorder disappeared after continuous glucose administration. After enucleation of the insulinoma, the administration of glucose was discontinued, and her blood glucose levels recovered. This case suggests that insulinoma should be considered by physicians and psychiatrists in the differential diagnosis of patients with symptoms presenting as RBD.

Abstract
Abstract
Background
Several studies showed that first-line bevacizumab plus chemotherapy for HER2-negative metastatic breast cancer improves progression-free survival and tumor response rate but not overall survival. MERiDiAN trial evaluated plasma vascular endothelial growth factor-A (VEGF-A) prospectively as a predictive biomarker for bevacizumab efficacy in metastatic breast cancer. However, results of this trial do not support using baseline plasma VEGF-A to identify patients benefitting most from bevacizumab. We measured baseline serum VEGF-A level from stored blood samples of metastatic breast cancer patient with treated bevacizumab plus paclitaxel as fist-line and later line therapy, and evaluated a correlation between serum VEGF-A level and efficacy of bevacizumab and prognosis of breast cancer patients tread with bevacizumab, retrospectively.
Patients and methods
We examined blood samples from 57 metastatic breast cancer patients treated with bevacizumab and paclitaxel, after obtaining written informed consent. And, we evaluated a correlation between baseline serum VEGF-A level and time to treatment failure (TTF) and overall survival (OS). We also compared the serum VEGF-A level of response group (CR and PR) and that of non-response group (SD and PD).
Results
Baseline serum level of VEGF-A ranged from 80 to 2079 pg/ml. Cases of treatment line were as follows: first-line, 22 cases (38.6%); second line, 11 cases (19.3%) and third-line and the later line, 24 cases (42.1%). The cutoff identified by ROC curve analysis that was able to differentiate response group and non-response group in first-line setting was 360pg/ml for serum VEGF-A. And, we separated high serum VGEF-A group and low serum VEGF-A group of patients treated with bevacizumab plus paclitaxel.
In patients treated as first line therapy, median TTF was 4.0 months with high serum VGEF-A group versus 5.0 months with low serum VEGF-A group, and median OS was 12 months with high serum VGEF-A group versus 11months with low serum VEGF-A group. There were no significant differences in both TTF and OS in first line setting. In patients treated as second line and later line therapy, median TTF was 2.8 months with high serum VGEF-A group versus 7.1 months with low serum VEGF-A group, and median OS was 6.4 months with high serum VGEF-A group versus 12.7 months with low serum VEGF-A group. The prognosis of high serum VEGF-A group was significantly worse than that of low serum group in both TTF and OS.
The serum VEGF-A level of response group was tend to be higher than that of non-response group in first line setting, and was lower in second and later line setting. However, there were no significant differences.
Conclusion
In this study, serum VEGF-A cannot be a predictor for efficacy of bevacizumab plus paclitaxel as first line therapy for metastatic breast cancer patients. On the other hand, there was a possibility that high serum level of VEGF-A can be a poor prognostic factor in late line therapy setting of bevacizumab.

Abstract
OBJECTIVE To examine characteristics of placebo responders and seek optimal criteria of early improvement with placebo for predicting subsequent placebo response in patients with schizophrenia. METHOD Data of 672 patients with schizophrenia randomized to placebo in nine double-blind antipsychotic trials were analyzed. Multiple logistic regression analyses were conducted to examine associations between placebo response at week 6 (i.e., a ≥ 25% reduction in the Positive and Negative Syndrome Scale [PANSS] score) and gender, age, study locations, baseline PANSS total or Marder 5-Factor scores, and per cent PANSS score reduction at week 1. Predictive power of improvement at week 1 for subsequent response was investigated; sensitivity and specificity of incremental 5% cutoff points between 5% and 25% reduction in the PANSS total score at week 1 were calculated. RESULTS Per cent PANSS total score reduction at week 1 and lower PANSS Marder disorganized thought scores at baseline were significantly associated with subsequent placebo response. A 10% reduction in a per-protocol analysis or a 15% reduction in last-observation-carried-forward analysis in the PANSS total score at week 1 showed the highest predictive power. CONCLUSION These findings are informative to identify potential placebo responders at the earliest opportunity for optimal trial design for schizophrenia.

Abstract
High precision measurements of the ground state hyperfine structure (HFS) of muonium is a stringent tool for testing bound-state quantum electrodynamics (QED) theory, determining fundamental constants of the muon magnetic moment and mass, and searches for new physics. Muonium is the most suitable system to test QED because both theoretical and experimental values can be precisely determined. Previous measurements were performed decades ago at LAMPF with uncertainties mostly dominated by statistical errors. At the J-PARC Muon Science Facility (MUSE), the MuSEUM collaboration is planning complementary measurements of muonium HFS both at zero and high magnetic field. The new high-intensity muon beam that will soon be available at H-Line will provide an opportunity to improve the precision of these measurements by one order of magnitude. An overview of the different aspects of these new muonium HFS measurements, the current status of the preparation for high-field measurements, and the latest results at zero field are presented.

Abstract
BACKGROUND Long-acting injectable antipsychotics (LAIs) are regarded as an important alternative to oral medication for patients with schizophrenia. However, LAIs remain under-utilized in clinical practice. AIMS The aims of this investigation were to 1) obtain information on patients' attitudes toward LAIs and 2) assess factors associated with patients' acceptance of LAIs, and 3) identify predictors of the discrepancy between patients and referring psychiatrists' opinions regarding the appropriateness for LAIs. METHODS Anonymized data were collected from a questionnaire distributed to 159 patients with schizophrenia and their referring psychiatrists at three psychiatric hospitals between February 2014 and July 2014. The patients completed an original questionnaire developed to evaluate their attitudes regarding LAIs. Regarding the appropriateness of LAI prescription, patients and their referring psychiatrists were asked to rate, on a 5-point scale, how appropriate they felt the depot prescription was for the patients. The participants also answered instruments to assess symptom severity, antipsychotic-induced extrapyramidal symptoms, functions, quality of life, and self-esteem levels. RESULTS Patients currently on LAIs have favorable attitudes toward LAIs with respect to side effects, relapse prevention, efficacy, pain, and cost. Expectation of relapse prevention was significantly associated with patients' acceptance of LAIs (answering that those drugs are appropriate for their own treatment). In addition, the discrepancy between the patients' and referring psychiatrists' opinions regarding the appropriateness of LAI treatment was significantly associated with symptom severity, expectation of relapse prevention, belief that LAIs are painful, and belief that LAIs offer a reduced range of antipsychotic choices. CONCLUSION Attitudes toward LAIs need to be considered when deciding whether to prescribe this formulation. Access to information on LAIs, including their benefit in relapse prevention, might enhance the acceptance and use of this formulation among patients with schizophrenia.

Abstract
OBJECTIVES To determine whether etiological beliefs are different among schizophrenia patients, their family, and medical staff. PATIENTS AND METHODS A cross-sectional study was performed at five hospitals and one mental clinic and included 212 patients, 144 family members, and 347 medical staff other than psychiatrists. A questionnaire about the possible etiological causes of schizophrenia was used. RESULTS There were significant differences in response scores among the three groups on using Angermeyer's and Goulding's classifications. Factor analyses revealed the following four subscales: Psychosocial, Biological, Environmental, and Cultural connotations. The structure varied among patients, family, and medical staff. CONCLUSION The perspectives of schizophrenia etiology were different among patients, family, and medical staff.

Abstract
Clinical effect and safety of recombinant human erythropoietin (r-HuEPO) were evaluated in 66 hemodialysis patients with intractable anemia. Initially, 50U/kg dry weight (DW) of r-HuEPO was administered intravenously at the end of every hemodialysis procedure for 4 weeks, then the dosage was increased to 100 and 200U/kg DW for poor responders. The patients’ hematocrits rose from 19.8 ± 2.3% (pretreatment) to 30.2 ± 4.9% after 12 weeks. From 206 U of blood transfusion requirement in the 3-month period before the study, only 34 U were needed after treatment. Serum iron and ferritin levels fell significantly during the study, and iron storage was considered to be one of the decisive factors in the response to r-HuEPO. Blood pressure rose in the course of r-HuEPO administration, but uncontrollable hypertension was rarely observed. There was no significant adverse effect of r-HuEPO except for this mild hypertension. These results indicate that r-HuEPO is an excellent therapeutic aid for the anemia associated with chronic renal failure.

Abstract
Background
The detection of circulating tumor cells (CTCs) in peripheral blood is an independent predictor of the efficacy of systemic therapy, and also a prognostic marker for patients with metastatic breast cancer. One of the main methods to detect CTCs is CellSearch system, which uses immune-magnetic separation followed by immunocytochemistry. A microdevice (CTChip from ClearCell system) can capture and enumerate CTCs based on distinctive physiological differences (size and deformability) between cancer cells and blood cells. CTChip thus obtains a larger CTC yield than affinity-based separation, which enriches a particular subgroup of cells expressing EpCAM. In this study, we enumerate CTCs in peripheral blood from early and metastatic breast cancer patients using a size-based method.
Patients and methods
We examined blood samples from a total of 18 early and metastatic breast cancer patients, after obtaining written informed consent. Blood samples were taken in sodium EDTA tubes after discarding the first 1ml of blood from the syringe. Two ml blood samples were applied to CTChip (ClearCell system), and CTCs were eventually trapped in the microwells of the CTChip. Trapped cells were analyzed by immunocytochemistry with monoclonal antibodies specific for leukocytes (CD45) and epithelial cells (CK8/18), along with 4',6-diamidino-2-phenylindole (DAPI) for nuclei: CK8/18-positive, DAPI-positive and CD45-negative cells more than 10 μm in diameter were defined as CTCs. Eight patients were examined using both the CTChip and CellSearch system to compare the yield of CTCs.
Results
Of 18 patients, 6 were de novo stage IV, 6 were recurrent and 6 were early stage breast cancer patients. Of primary tumors, 8 were HER2- and ER and/or PR +, 6 were HER2-and ER- and PR-, 3 were HER2+ and ER and/or PR +, and one was HER2+ and ER- and PR-. Using CTChip, detected CTCs ranged from 3 - 107 cells/2 ml in all cases: 3 - 83 for early stage, 19 - 156 for stage IV and 21 - 146 for recurrent. The number of CTCs found in recurrent patients tended to be higher than in early stage patients. Size-based method using CTChip clearly showed high sensitivity compared with the CellSearch system, which detected CTCs in only 2 cases out of 8. In analysis by immunochemistry, we found CK-negative, CD45-negative and DAPI positive cells with larger diameter (>16 μm) than CK-positive CTCs in most patients, and the numbers were higher in stage IV (8.5 cells of median value) and recurrent (13 cells) patients than in early stage patients (1.5 cells). Our study suggested that CK-negative large cells might be CTCs with epithelial–mesenchymal transition (EMT).
Conclusion
This size-based technology enables us to capture CTCs regardless of EpCAM expression. Enumerated CTCs varied in size and positivity of CK8/18, suggesting the heterogeneity of CTCs. Further research, especially focusing on EMT will be crucial to understand the key mechanism of metastasis and drug resistance.

Abstract
Abstract
Background:
To avoid tissue expander exposure following mastectomy flap necrosis, several methods for covering expander by autologous flap in cases of immediate breast reconstruction have been reported. These methods are classified into two groups, complete or partial expander coverage. Two methods have potential risks of postoperative complications following: insufficient lower pole expansion and cranial migration in complete coverage methods, and lateral migration in partial coverage methods. However, the comparisons of complication rates between these two methods have not been reported. This study aims to compare the incidence of expander exposure following mastectomy flap necrosis and expander migration between two methods.
Methods:
A retrospective review of 93 patients (99 breasts) who underwent immediate expander-based breast reconstruction was performed. Patients were divided into two groups, complete or partial expander coverage by autologous flaps. In both groups, expanders were placed into subpectral position. In partial coverage group, the lateral borders of pectralis major muscles were sutured to the mastectomy skin flaps. If the skin flap was too thin to be sutured, the serratus anterior muscro-fascial flap was dissected and sutured to the lateral border of pectralis major muscle to cover the expander completely. Allograft products were not used in both groups. Demographics, intraoperative findings, and postoperative complications were compared between two groups.
Results:
Of the 99 breasts, 56 underwent complete expander coverage and 43 underwent partial coverage. Mastectomy flap necrosis rate was higher in the complete coverage group (Complete 14.3% versus Partial 0%; p=0.0091), however, there was no incidence of expander exposure in both groups. Lateral migration rate was higher in the partial coverage group (Complete 0% versus Partial 9.3%; p=0.033). There was no difference in cranial migration rate between two groups (Complete 12.5% versus Partial 2.3%; p=0.133).
Conclusions:
The thinness of the mastectomy flaps was considered to provide the higher incidence of mastectomy flap necrosis in the complete coverage group. The complete expander coverage reduced lateral migration rate and prevented expander exposure in cases of mastectomy flap necrosis.

Abstract
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy occurring in upper limbs. The etiology, however, has not been fully understood yet. Median nerve could be compressed by either increase of carpal tunnel pressure (CTP) or direct impingement when it is forced toward to carpal ligament especially in wrist flexion leading to CTS development. Thus, the increase of carpal tunnel pressure is considered an important role in CTS development. It has been identified that forces applied to the palm would affect the CTP. However, the quantitative relationship between palmar contact force and CTP is not known. The purpose of this study was to quantitatively evaluate the relationship between palmar contact force and CTP. Eight human cadaveric hands were used. The CTP was measured with a diagnostic catheter-based pressure transducer inserted into the carpal tunnel. A custom made device was used to apply forces to the palm for the desired CTP. Palmar contact forces corresponding to the determined CTP level were recorded respectively. The testing was repeated with different ranges of tension applied to the flexor digitorum superficialis tendon of the third finger. The tensions were constant at 50 g for the other flexor tendons and median nerve. The results showed that CTP increased linearly with the force applied to the palm. When CTP was 30 mmHg, mean values of the contact force to the palm was 293 g (SD: 15.2) including all tensions. These results would help to understand the effect of daily activities with hands on CTP.

Abstract
Carpal tunnel pressure is a key factor in the etiology of carpal tunnel syndrome. Numerous approaches have been conducted to measure carpal tunnel pressure. However, most techniques are invasive and take time and effort. We have developed an innovative approach to noninvasively assess the tunnel pressure by using the ultrasound surface wave elastography (USWE) technique. In a previous study it was shown that the shear wave speed in a tendon increased linearly with increasing tunnel pressure enclosed the tendon in a simple tendon model. This study aimed to examine the relationship between the carpal tunnel pressure and the shear wave speeds inside and outside the carpal tunnel in a human cadaveric model. The result showed that the shear wave speed inside the carpal tunnel increased linearly with created carpal tunnel pressure, while the shear wave speed outside the carpal tunnel remained constant. These findings suggest that noninvasive measurement of carpal tunnel pressure is possible by measuring the shear wave speed in the tendon. After fully establishing this technology and being applicable in clinic, it would be useful in the diagnosis of carpal tunnel syndrome. For that reason, further validation with this technique in both healthy controls and patients with carpal tunnel syndrome is required. © 2017 Orthopaedic Research Society.

Abstract
A nationwide retrospective study for the clinical outcomes of 99 patients who had received thymoglobulin at a median total dose of 2.5 mg/kg (range, 0.5-18.5 mg/kg) as a second-line treatment for steroid-resistant acute GvHD was conducted. Of the 92 evaluable patients, improvement (complete or partial response) was observed in 55 patients (60%). Multivariate analysis demonstrated that male sex and grade III and IV acute GvHD were associated with a lower improvement rate, whereas thymoglobulin dose (<2.0, 2.0-3.9 and ⩾4.0 mg/kg) was NS. Factors associated with significantly higher nonrelapse mortality included higher patient age (⩾50 years), grade IV acute GvHD, no improvement of GvHD and higher dose of thymoglobulin (hazard ratio, 2.55; 95% confidence interval, 1.34-4.85; P=0.004 for 2.0-3.9 mg/kg group and 1.79; 0.91-3.55; P=0.093 for ⩾4.0 mg/kg group). Higher dose of thymoglobulin was associated with a higher incidence of bacterial infections, CMV antigenemia and any additional infection. Taken together, low-dose thymoglobulin at a median total dose of 2.5 mg/kg provides a comparable response rate to standard-dose thymoglobulin reported previously, and <2.0 mg/kg thymoglobulin is recommended in terms of the balance between efficacy and adverse effects.

Abstract
Dual-energy subtraction digital tomosynthesis with pulsed X-ray and rapid kV switching was used to examine calcifications in pulmonary lesions. The digital tomosynthesis system used included a conventional fluororadiographic TV unit with linear tomographic capabilities, a high resolution videocamera, and an image processing unit. Low-voltage, high-voltage, and soft tissue subtracted or bone subtracted tomograms of any desired layer height were reconstructed from the image data acquired during a single tomographic swing. Calcifications, as well as their characteristics and distribution in pulmonary lesions, were clearly shown. The images also permitted discrimination of calcifications from dense fibrotic lesions. This technique was effective in demonstrating calcifications together with a solitary mass or disseminated nodules.

Abstract
Recent immunosuppressive treatments for lupus nephritis have improved renal survival rate, however, there still exists lupus nephritis refractory to these treatments. Angiotensin receptor blockers (ARBs) are known not only to decrease blood pressure but also to have an independent renoprotecting effect by interrupting renin-angiotensin system. The aim of this study was to evaluate whether ARBs have an additive effect on refractory lupus nephritis. Enrolled in this trial were twelve patients with lupus nephritis who were diagnosed by renal biopsy and remained proteinuria despite corticosteroids and/or immunosuppressive treatments. ARB, losartan or candesartan, was administered for six months. Various clinical parameters were compared before and after ARB administration. Proteinuria decreased after ARB treatment in 83% of the patients and the median amount of proteinuria significantly decreased from 2530 mg/gCr to 459 mg/gCr (P = 0.03). In addition, serum albumin and cholesterol levels were significantly improved. Systolic blood pressure significantly decreased, but none had symptoms of hypotension. The antiproteinuric effect of ARB did not correlate with the reduction of blood pressure. Interestingly, higher total complement activity levels before ARB treatment were associated with a greater reduction of proteinuria. The addition of ARB would be a safe and effective treatment for lupus nephritis with persistent proteinuria despite corticosteroids and/or immunosuppressive treatments.

Abstract
The aim of this study was to determine the effects of low-voltage electrochemotherapy with intraperitoneal cisplatin on hamster oral fibrosarcoma. Oral fibrosarcoma was transplanted sub-mucosally into the cheek pouch mucosa of 100 hamsters. After transplantation, the hamsters were randomly divided into four equal groups. These groups received no treatment (D-E-); 2 mg/kg body weight cisplatin treatment without electroporation (D+E-); electroporation without cisplatin treatment (D-E+);or 2 mg/kg body weight cisplatin treatment followed by electroporation (D+E+). Electrical pulse treatment together with cisplatin injection markedly reduced the size of the tumour, whereas cisplatin injection or electrical pulse treatment alone did not. These results clearly indicate that the anti-tumour effect of cisplatin on hamster oral fibrosarcoma was considerably potentiated or enhanced by the administration of local electrical pulses at low voltages.

Abstract
Abstract
Background:
Neoadjuvant chemotherapy (NAC) with taxanes, followed by fluorouracil, epirubicin, and cyclophosphamide (FEC), with concurrent trastuzumab is known to achieve a high pCR rate of more than 60% for HER2-positive breast cancer (BC) as well as good prognoses in those obtaining pCR. On the other hand, the prognostic significance of tumor-infiltrating lymphocytes (TILs) has recently been described in triple-negative BC. However, the prognostic and predictive values of TILs in HER2-positive BC remain unclear. In the present study, we examined the grades of TILs in pre-treatment cancer tissues and residual tumors after NAC with trastuzumab, and also investigated its predictive utility for pCR and prognostic power for HER2-positive BC.
Patients and Methods:
A total of 128 Japanese women with HER2-positive BC received either paclitaxel or docetaxel followed by FEC, with concomitant trastuzumab. The proportional grades of stromal (Str)-TILs in pre-treatment biopsy specimens and residual tumors after NAC with trastuzumab were determined as follows: low grade (0-10%), intermediate grade (10-40%), and high grade (40-90%), using the criteria of the International Working Group for TILs in BC. Analysis 1: The relationship between the grades of Str-TILs in pre-treatment tumors and pCR rates was investigated. Relapse-free survival (RFS) and cancer-specific survival (CSS) were analyzed for a correlation with pre-treatment Str-TILs. Analysis 2: Alterations in the grade of Str-TILs were examined in the residual tumors of non-pCR patients, and RFS and CSS were analyzed for a correlation with residual Str-TILs.
Results:
pCR was achieved in 83 out of the 128 patients (pCR rate, 64.8%) who received NAC with trastuzumab, and RFS was significantly better in the pCR group than in the non-pCR group (p = 0.0071). Analysis 1: The patient distribution of the Str-TILs grade in pre-treatment tumors was as follows: high: 24 (18.8%); intermediate: 38 (29.7%); and low: 66 (51.6%). pCR rates correlated with the Str-TILs grade in pre-treatment tumors: 83.3% in the high group, 71.1% in the intermediate group, and 54.5% in the low group (p = 0.026); however, the Str-TILs grade in pre-treatment tumors did not correlate with survival. Analysis 2: In 45 non-pCR patients, the distribution of the Str-TILs grade in residual tumors was as follows: high: 9 (20.0%); intermediate: 8 (17.8%); and low: 28 (62.2%), respectively. In non-pCR patients, the rate of a high Str-TILs grade was greater in residual tumors than in pre-treatment tumors (residual, 20.0%, pre-treatment, 8.9%). RFS was significantly better with a high grade than with a low grade of residual Str-TILs (p = 0.033).
Conclusions:
The status of TILs in pre-treatment tumors predicted responses to NAC concomitant with trastuzumab in HER2-positive BC. The grade of TILs was higher in residual tumors than in pre-treatment tumors, and, among non-pCR patients, the prognosis of patients with a high residual-TILs grade was better prognosis than that of patients with a low residual-TILs grade. We speculate that an examination of TILs in residual tumors after NAC with trastuzumab may be necessary for selecting patients with a good prognosis from non-pCR patients.

Abstract
OBJECTIVES Restless legs syndrome (RLS) is a sensorimotor disturbance that causes the production of impulses and dysesthesia and makes the patients feel as though they must move their lower extremities. Because the symptoms of RLS in the lower limbs tend to develop at night, RLS could cause sleep disorders. We investigated an association between the symptoms of RLS and the health-related quality of life among community-dwelling individuals in Japan. METHODS In this cross-sectional survey, we enrolled 985 volunteers who participated in the Iwaki Health Promotion Project in 2013. The symptoms of RLS were evaluated by the criteria of the International Restless Legs Syndrome Study Group. The assessments included an interview to obtain sociodemographic data, the second version of the Short Form Health Survey, the Center for Epidemiological Studies Depression scale, and the Pittsburgh Sleep Quality Index. A multiple regression analysis was used to assess the relationship between the symptoms of RLS and subscores of the Short Form Health Survey, Version 2. RESULTS The overall prevalence of RLS in our participants was 1.0%. We found a significant and negative association between symptoms of RLS and physical functioning, role - physical functioning, bodily pain, social functioning, and the physical composite summary score. CONCLUSION After adjusting for confounders such as age, sex, and comorbidity, the burden of RLS appears to be mainly a physical problem. Impaired health-related quality of life among community individuals with RLS emphasizes the importance of screening for these symptoms and evaluating the need for treatment.

Abstract
AIM The purpose of this study was to investigate changes in muscle oxygenation of knee extensor and plantar flexor muscles during repeated muscle contractions under the same condition. In addition, we compared changes in muscle oxygenation between superficial and deep regions of both muscles. METHODS Eleven healthy males participated in this study. During repeated knee extensions and plantar flexions (50 repetitions at 50% of the isometric maximum voluntary contraction for 3 s with 3 s relaxations), blood volume and oxygen saturation (StO₂) of the vastus lateralis and medial gastrocnemius muscles (superficial and deep region of each muscle) were measured using near infrared spectroscopy. RESULTS The decrement of StO₂at the end of exercises was greater in plantar flexor muscle than in knee extensor muscle (P<0.001). For both muscles, the decrement of StO₂at the end of exercises was greater in the deep region than in the superficial one (both P<0.001). CONCLUSION These results suggested that the oxygen utilization of plantar flexor muscle and deep regions of each muscle were higher than that of knee extensor muscle and superficial regions of each muscle.

Abstract
Previous studies demonstrated that treatment involving eccentric training was effective in the conservative management of chronic tendinosis. However, the mechanisms for these phenomena are unknown. The purpose of this study was to compare changes in blood circulation of the tendons after the repeated concentric and eccentric contractions. 11 healthy males volunteered for this study. Subjects performed the repeated concentric (CON) and eccentric (ECC) contractions (5 sets of 10 maximal voluntary contractions) of the plantar flexors. During and after repeated contractions, oxyhemoglobin (Oxy), deoxyhemoglobin (Deoxy), total hemoglobin (THb), and oxygen saturation (StO2) of the Achilles tendons were measured using red laser lights. Oxy and THb increased during and after ECC, but not CON. Deoxy decreased during both CON and ECC. Increase in StO2 during and after ECC was greater than that during and after CON. These results suggested that changes in blood circulation of the Achilles tendon during and after repeated eccentric contractions were more remarkable than those during and after repeated concentric contractions.

Abstract
In unrelated hematopoietic SCT (HSCT), HLA allele mismatch has been shown to have a significant role. To clarify the importance of HLA allele mismatch in the GVH direction in related HSCT, we retrospectively evaluated 2377 patients who received stem cells from an HLA serologically matched related donor in the GVH direction using the database of the Japan Society for Hematopoietic Cell Transplantation. The cumulative incidences of grade II-IV and grade III-IV acute GVHD in patients with an HLA allele-mismatched donor (n=133, 5.6%) were significantly higher than those in patients with an HLA allele-matched donor. Multivariate analyses showed that the presence of HLA allele mismatch was associated with increased risks of grade II-IV and grade III-IV acute GVHD. In particular, HLA-B mismatch and multiple allele mismatches were associated with an increased risk of acute GVHD. The presence of HLA allele mismatch was associated with an inferior OS owing to an increased risk of non-relapse mortality (NRM). In conclusion, the presence of HLA allele mismatch in the GVH direction in related HSCT was associated with increased risks of GVHD and NRM, which led to an inferior OS. HLA allele typing is recommended in related HSCT.
