Abstract
Allogeneic hematopoietic cell transplant (HCT) is a curative procedure for myeloid malignant neoplasms, but relapse after HCT remains critical. A conditioning regimen involving granulocyte colony-stimulating factor-combined high-dose cytarabine, cyclophosphamide, and total body irradiation (G-CSF-combined high-dose cytarabine/cyclophosphamide/total-body irradiation [HDCA/CY/TBI]) was reported to improve outcomes after cord blood transplant (CBT) for myeloid malignant neoplasms, but this regimen was not previously evaluated among patients undergoing bone marrow transplant (BMT) or peripheral blood stem cell transplant (PBSCT). METHODS We retrospectively analyzed 28 patients who underwent allogeneic HCT including BMT from a related (1 patient) or unrelated donor (9 patients), PBSCT from a related donor (7 patients), or single-unit CBT from an unrelated donor (11 patients) after a G-CSF-combined HDCA/CY/TBI regimen. RESULTS All patients achieved neutrophil and platelet engraftment, which were significantly more rapid in the BMT/PBSCT group than in the CBT group. Eighteen patients were alive at a median follow-up of 54.3 months. The 3-year relapse and nonrelapse mortality rates were 28.6% and 7.1%, respectively, which were similar between the BMT/PBSCT and CBT groups. Overall survival and disease-free survival at 5 years after HCT were 62.6% and 64.3%, respectively, which were also similar between the BMT/PBSCT and CBT groups. Only disease status at HCT had a significant impact on overall survival and disease-free survival (86.7% with standard risk vs 38.5% with high risk and 86.7% with standard risk vs 38.5% with high risk, respectively). CONCLUSION A G-CSF-combined HDCA/CY/TBI regimen is a promising conditioning in patients with myeloid malignant neoplasms who undergo not only CBT but also BMT or PBSCT.

Abstract
Objectives Unicompartmental knee arthroplasty (UKA) is one surgical option for treating symptomatic medial osteoarthritis. Clinical studies have shown the functional benefits of UKA; however, the optimal alignment of the tibial component is still debated. The purpose of this study was to evaluate the effects of tibial coronal and sagittal plane alignment in UKA on knee kinematics and cruciate ligament tension, using a musculoskeletal computer simulation. Methods The tibial component was first aligned perpendicular to the mechanical axis of the tibia, with a 7° posterior slope (basic model). Subsequently, coronal and sagittal plane alignments were changed in a simulation programme. Kinematics and cruciate ligament tensions were simulated during weight-bearing deep knee bend and gait motions. Translation was defined as the distance between the most medial and the most lateral femoral positions throughout the cycle. Results The femur was positioned more medially relative to the tibia, with increasing varus alignment of the tibial component. Medial/lateral (ML) translation was smallest in the 2° varus model. A greater posterior slope posteriorized the medial condyle and increased anterior cruciate ligament (ACL) tension. ML translation was increased in the > 7° posterior slope model and the 0° model. Conclusion The current study suggests that the preferred tibial component alignment is between neutral and 2° varus in the coronal plane, and between 3° and 7° posterior slope in the sagittal plane. Varus > 4° or valgus alignment and excessive posterior slope caused excessive ML translation, which could be related to feelings of instability and could potentially have negative effects on clinical outcomes and implant durability.

Abstract
Aims Total ankle arthroplasty (TAA) has become the most reliable surgical solution for patients with end-stage arthritis of the ankle. Aseptic loosening of the talar component is the most common complication. A custom-made artificial talus can be used as the talar component in a combined TAA for patients with poor bone stock of the talus. The purpose of this study was to investigate the functional and clinical outcomes of combined TAA. Patients and Methods Ten patients (two men, eight women; ten ankles) treated using a combined TAA between 2009 and 2013 were matched for age, gender, and length of follow-up with 12 patients (one man, 11 women; 12 ankles) who underwent a standard TAA. All had end-stage arthritis of the ankle. The combined TAA features a tibial component of the TNK ankle (Kyocera, Kyoto, Japan) and an alumina ceramic artificial talus (Kyocera), designed using individualized CT data. The mean age at the time of surgery in the combined TAA and standard TAA groups was 71 years (61 to 82) and 75 years (62 to 82), respectively. The mean follow-up was 58 months (43 to 81) and 64 months (48 to 88), respectively. The outcome was assessed using the Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale, the Ankle Osteoarthritis Scale (AOS), and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). Results The mean preoperative JSSF score of the combined TAA and standard TAA groups was 44 (sd 11) and 49 (sd 10), respectively. The mean postoperative JSSF scores were 89 (sd 6.1) and 72 (sd 15), respectively. The mean postoperative JSSF score of the combined TAA group was significantly higher (p = 0.0034). The mean preoperative AOS scores for pain and function in the combined TAA and standard TAA groups were 5.8 (sd 3.3) and 5.5 (sd 3.1), and 8.6 (sd 1.3), and 7.1 (sd 2.9), respectively. The mean postoperative AOS scores of pain and function were 2.5 (sd 2.5) and 2.2 (sd 1.9), and 2.5 (sd 3.3) and 3.4 (sd 2.9), respectively. There were no significant differences between the two groups in terms of postoperative AOS scores. The mean postoperative SAFE-Q scores were: for pain, 76 (sd 23) and 70 (sd 23); for physical function, 66 (sd 25) and 55 (sd 27); for social function, 73 (sd 35) and 62 (sd 34); for shoe-related, 73 (sd 19) and 65 (sd 26); and for general health, 78 (sd 28) and 67 (sd 29), respectively. There were no significant differences between the two groups in terms of postoperative SAFE-Q scores. Conclusion Combined TAA resulted in better clinical results than standard TAA.

Abstract
Aims The aim of this study was to determine the diagnostic utility of histological analysis in spinal biopsies for spondylodiscitis (SD). Patients and Methods Clinical features, radiology, results of microbiology, histology, and laboratory investigations in 50 suspected SD patients were evaluated. In 29 patients, the final (i.e. treatment-based) diagnosis was pyogenic SD; in seven patients, the final diagnosis was mycobacterial SD. In pyogenic SD, the neutrophil polymorph (NP) infiltrate was scored semi-quantitatively by determining the mean number of NPs per (×400) high-power field (HPF). Results Of the 29 pyogenic SD patients, 17 had positive microbiology and 21 positive histology (i.e. one or more NPs per HPF on average). All non-SD patients showed less than one NP per HPF. The presence of one or more NPs per HPF had a diagnostic sensitivity of 72.4%, specificity 100%, accuracy 100%, positive predictive value (PPV) 81.0%, and negative predictive value (NPV) 61.9%. Sensitivity, specificity, and accuracy were greater using the criterion of positive histology and/or microbiology than positive histology or microbiology alone. Granulomas were identified histologically in seven mycobacterial SD patients, and positive microbiology was detected in four. Conclusion The diagnosis of pyogenic SD was more often confirmed by positive histology (one or more NPs per HPF on average) than by microbiology, although diagnostic sensitivity was greater when both histology and microbiology were positive.

Abstract
Abstract
Background: Chronic pain after breast cancer surgeryhas harmful effects on patients' daily life. Paravertebral block (PVB) can prevent not only acute but chronic pain after breast cancer surgery, although the block is not easily put into practice because of technical difficulty or necessity to change patients' position. Thoracic interfascial nerve blocks (TINB) have been reported that it gives similar analgesic efficacy as PVB as with fewer risks, however there are no reports comparing analgesic efficacy of PVB with TINB. Although there are several scales evaluating postoperative pain including visual analog scale (VAS) or numerical rating scale, Quality of Recovery (QoR) have been set up to assess the impact of postoperative morbidity on patients' ability to return to normal function and quality of life. Among those assessment scales, QoR-40 has been mainly applied. It consists of 40 questions including five dimensions: psychologic support, physical comfort, emotional state, physical independence, and pain. There is a report suggesting that PVB improve QoR-40 after ambulatory breast tumor resection.
Methods: This is a single center single arm phase 2 study for early breast cancer patients. Exclusion criteria are pregnant and parturient women, allergy to local anesthetics, significant psychiatric or mental disorders, and patients with chronic pain. All blocks are subjected to ultrasound guidance. Patients were randomized to receive PVB with 40 ml ropivacaine or TINB with 60 ml ropivacaine. TINB consisted of modified PECS II block and transversus thoracic muscle plane block. For assessment of QoR, QoR-40 score which was consisted of 5 elements including postoperative pain was used. The trial was activated in July 2016.
Statistical Method: We conducted a pilot study on 16 patients who received a PVB during breast cancer surgery. Based on the standard deviation (SD) of QoR-40 on postoperative day (POD) 1, the SD was set to 7.2. Since the non-inferiority limit needs to be reduced to about half as much as the effect quantity used in the average value superiority test, it is set to 8, which is half of the effect quantity 16 in the pilot study. When one-sided test with α error = 0.025 and β error = 0.2, about 13 cases in each group are required. Given that dropout rate is about 30-40%, 18 cases in each group were taken as the number of subject cases.
Results: Thirty-six patients were accrual, 18 of PVB group and 18 of TINB group. Two patients declined the trial, 36/38 (95%) acceptors completed the trial. Total of QoR-40 scores on POD 1 was designated as the primary outcome. For secondary outcomes, both QoR-40 score and pain score were assessed on POD 3 and in postoperative month(s) 1, 3, 6, 12. Other secondary outcomes included pain score by POD 1, incidence of rescue analgesia, time to rescue analgesia, incidence of nausea and vomiting. All patients provided written informed consent before undergoing any study-related procedures.
Conclusions: This trial will provide non-inferiority that TINB preserve the effect of QoR as good as PVB after breast cancer surgery.

Abstract
Abstract
Background
Neoadjuvant chemotherapy (NAC) is established for treatment of locally advanced disease and is being used increasingly for early-stage breast cancer. And sentinel lymph node biopsy (SLNB) for clinically node-negative breast cancer patients after NAC is performed as a daily procedure. The purpose of this study was to identify the group that can omit SLNB in patients with clinically node-negative breast cancer at diagnosis before NAC.
Materials and Methods
A single institutional retrospective analysis was performed. 126 patients were diagnosed as clinically node-negative before NAC and underwent SLNB between 2005 and 2017.
Before NAC, all patients underwent clinical assessment of lymph-node status by palpation and axillary ultrasound. We judged patients to be node-negative when palpation and ultrasound showed no suspicious nodes. If axillar lymph nodes were swelling, fine-needle aspiration cytology was performed. After NAC, clinical assessment of lymph-node status was performed, again.
119 patients received anthracycline-based (anthracycline alone: 11, anthracycline followed by taxane: 108) chemotherapy and 7 patients received taxane alone. Clinical complete response (cCR) was defined if there was no evidence of tumor in the breast and axillary lymph nodes by US and MRI. SLNB procedure was done after NAC in all patients. Lymphatic mapping was performed with radioactive colloid and/or lymphatic blue dye.
Results
Median follow-up time was 51.2months. cCR rate was 16.7% (21/126).
Success rate for the identification and removal of a SLN was 96.8% (122/126). The median number of SLNs removed was 1.9 (1-5).
15 patients (12.3%) represented SLN positive in patients who were diagnosed as clinically node-negative before NAC. They were performed axillar dissection and the SLNs were the only positive nodes in 9 patients.
No SLNs metastases were observed in 21 patients who were diagnosed as cCR by ultrasound and MRI. And 15 patients (14.9%) had positive SLN in the 101 patients who were diagnosed as clinical partial response or clinical stable disease (p=0.071).
Tumor size, Surgical procedures, hormone receptor status and HER2 status did not influence the positive rate of SLN metastases.
No axillar lymph node recurrence was observed within follow-up period.
Conclusion
Our results show that SLNB is necessary even in breast cancer patients who were diagnosed as initially clinically node-negative before NAC.
However, SLNB may be omitted in breast cancer patients who were diagnosed as clinically node-negative by palpation and axillary ultrasound before NAC and as cCR by ultrasound and MRI after NAC.

Abstract
Abstract
Purpose
Recently a sentinel lymph node biopsy has been a part of standard surgical procedure instead of an axillary dissection with a mastectomy for breast cancers. It is necessary to make an accurate diagnosis of lymph node metastasis for deciding surgical procedure either a sentinel lymph node biopsy or an axillary dissection. Preoperative ultrasound is one of widely used tools to make a diagnosis of sentinel lymph node. This study presents results regarding preoperative pathological features to improve diagnosis accuracy of sentinel lymph node by preoperative axillary ultrasound.
Materials and methods
One doctor performed preoperative ultrasound. He used HITACHI HI VISION Ascendus. Axillary lymph node metastasis was suspected when these findings were observed such as partial thickening of lymph node cortex, loss of lymph nodes' hilum, circular swelling shape change and difference compared to a contralateral axillary lymph node. When we suspected axillary lymph node metastasis, we performed fine needle aspiration cytology except other findings such as CT, MRI or physical appearance showed obvious axillary lymph node metastasis. Preoperative core needle biopsies were performed to determine pathologic types and hormone characters. Clinical cases such that ductal carcinoma in situ, lobular carcinoma and ones with primary systemic treatment (neoadjuvant therapy) were excluded from statistical analysis.
Results
During a study period between April 2015 and December 2017, altogether 662 patients were participated in this study. 304 cases were analyzed by statistical analysis. 268 cases were diagnosed as negative and 36 case as positive in axillary lymph node metastasis by preoperative ultrasound. In the 268 cases 225 cases were diagnosed as negative by sentinel lymph node biopsy during operations (84.0%) but 43 cases were diagnosed as positive (16.0%). 23% cases included less than 20mm micro metastasis (10/43). To investigate correlation between false negative ratio of axillary lymph node metastasis diagnosed by an ultrasound and preoperative pathological features such as hormone receptor, HER2, Ki-67, nuclear grade and subtypes (Luminal, Her2 and triple negative). The false negative ratio was 17.0% vs 11.1% in hormone receptor (positive vs negative, p = 0.434), 14.5% vs 16.0% in HER2 (positive vs negative, p = 0.887), 15.4% vs 19.1% in Ki-67 (<20% vs ≥20%, p = 0.441), 18.4% vs 9.38% in nuclear grade (1 vs 2 and 3, p = 0.997), 11.3% vs 23.8% vs 16.7% vs 16.7% (Luminal A vs Luminal B vs Her2 vs triple negative, p>0.05).
Conclusion
There were no statistical significant difference between the axillary lymph node metastasis diagnosed by an ultrasound and the preoperative pathological features. However cases categorized in Luminal B by preoperative pathology had relatively high false negative ratio of axillary lymph node metastasis diagnosed by an ultrasound. It is necessary to investigate a way to improve diagnosis accuracy of sentinel lymph node by a preoperative axillary ultrasound.

Abstract
Abstract
Background: Selected therapeutic personalized peptide vaccines (PPV) were effective for boosting anticancer immune response that was associated with the clinical outcome as a prognostic factor for metastatic recurrent breast cancer (mrBC) 1-2. In this study, we investigated the immunological and clinical effect of PPV as the prophylactic cancer vaccine for non-recurrent but high-risk BC (nrhrBC) patients (pts), and we compared it's features to those of the mrBC pts who had active cancers or became resistant to the standard therapies(TR-mrBC). Methods: Material and Patient eligibility criteria: The peptides were selected from the 31 PPVs according to the results of HLA typing and peptide-specific IgG titers. Pts with a histological diagnosis of BC and their HLA-A molecules should be each of -A2, A3, A11, A24, A26, A31 or A33. The clinical protocols were approved by the institutional review board. (UMIN000003081and 00000184400000). Treatment schedule: A maximum of 4 peptides was administrated as weekly for initial four vaccinations and as biweekly for further inoculations. The concomitant standard endocrine therapy and the chemo-endocrine therapy were available for nrhrBC pts after finishing the standard adjuvant chemotherapy, and for mrBC pts concurrently. Immune and clinical response assessment: Specific T-cell responses, IgG titers and cytokines were evaluated using by interferon (IFN)-γ ELISPOT, Luminex assay and ELISA system in every 6-8 vaccinations. Toxicity, clinical response and correlation with the immune responses were investigated. Results: 16 pts with nrhrBC, 41 pts with mrBC and 79 pts with TR-mrBC received median 18, 16 and 14 vaccines, respectively. After PPV therapies, peptide-specific IgG and CTLs increased significantly in a total of 47 (77%) and 37(60%) in nrhrBC pts, 102 (63%) and 98 (61%) in mrBC pts, and 150(53%) and 100 (42%) in TR-mrBC pts. Pts experienced Grade 1-3 skin reaction at injection site, no other grade 3 or 4 SAEs were associated with PPV but with the disease progression or combination therapy. The median time to progression (TTP) and overall survival (OS) were not reached in nrhrBC pts, 7.8 and 29 months in mrBC pts, and were 7.5 and 15.9 months in TR-mrBC pts, respectively. The peptide specific CTL response was correlated significantly with OS in nrhrBC pts and the IgG levels were associated with the better OS in either non TR-mrBC pts or TR-mrBC pts. High levels of IL-6, GM-CSF, IFN-g, IL-2 receptor, BAFF were associated with worse prognosis for pts with TR-mrBC. And high levels of GM-CSF and BAFF were associated with worse prognosis for pts with nrhrBC and mrBC, respectively. In contrast, High levels of IL-2 were associated with the better prognosis for pts with mrBC. Conclusion: This study indicated that immunological features of these three groups were different from each other with most potent PPV-induced immune boosting for nrhrBC pts. Pts with mrBC who had lower immune-suppressive cytokine levels had the better prognosis. These results suggested the PPV therapy could be effective for postoperative prophylactic vaccination in patients with nrhrBC. References: 1. Takahashi R, Toh U, et al. Breast Cancer Res. 2014; 2.

OBJECTIVES Living donor kidney transplant relieves the disease burden of patients with end-stage renal disease but may shorten donor life expectancy; however, their quality of life (QOL) is preserved. Nevertheless, the magnitude of the net gain of this procedure is unknown. We evaluated the QOL of both donors and recipients concurrently and calculated the net utility gain. METHODS We recruited 210 subjects who visited the kidney transplantation clinic of a university hospital. Subjects were asked to complete the 5-level EQ-5D-based questionnaire, and patient characteristics were extracted from their medical records. We performed multivariate tobit models analysis to evaluate the QOL change caused by transplant surgery and subsequently ran computational simulations to determine the net utility gains of donors and recipients. We also performed sensitivity analyses. RESULTS After excluding 16 answers with missing data, we analyzed 203 answers in total. After the transplant surgery, recipients gained 0.07 in utility value while donors lost 0.04. In the net utility analysis, we found that the quality-adjusted life years gained ranged from 7.2 to 7.8 in the most favorable case observed in the combination of middle-aged recipients and elderly donors. Assuming no utility discount, the most favorable combination was that with older donors and younger recipients. CONCLUSIONS These findings indicated that the QOL improvement in recipients was larger than the loss among donors. When calculating the net utilities, a combination of middle-aged recipients and elderly donors yielded the largest net utility, but this was likely derived from assumption in the discount of QOL.

Abstract
INTRODUCTION The Musculoskeletal Infection Society (MSIS) has defined specific clinical and laboratory criteria for the diagnosis of periprosthetic joint infection (PJI). In this study we assessed the diagnostic utility of MSIS microbiological and histological criteria for PJI in 138 cases of septic and aseptic knee implant failure. MATERIALS AND METHODS Intra-operative samples from 60 cases of knee septic implant failure (SIF) and 78 cases of aseptic implant failure (AIF), defined on the basis of clinical, laboratory and operative findings/surgical management, were analysed microbiologically and histologically. Findings were correlated with the final clinical diagnosis and the specificity, sensitivity, accuracy, positive and negative predictive value of MSIS microbiological and histological criteria for knee PJI were assessed. RESULTS 80% of SIF cases showed culture of the same organism from two or more samples (ie MSIS microbiological criteria for definite PJI); 8.3% grew an organism from one sample, and 11.7% showed no growth from any sample. 23.1% of AIF cases grew an organism from one sample and 76.9% showed no growth from any sample. MSIS histological criteria for PJI identified 96.7% of SIF cases. The sensitivity, specificity, accuracy and positive and negative predictive value of MSIS histological criteria for PJI were 96.7%, 100%, 98.6%, 100% and 97.5%, respectively. MSIS microbiological and histological criteria identified all AIF cases. CONCLUSIONS Knee PJI is more often identified by current MSIS histological than microbiological criteria. A significant proportion of SIF cases show either no growth or growth of an organism from only one sample. AIF is identified by both MSIS microbiological and histological criteria. Correlation of clinical, radiological and laboratory findings is required for the diagnosis of knee PJI.

Abstract
BACKGROUND Localised (transthyretin-associated) amyloid is commonly seen in articular/periarticular tissues of elderly individuals. Whether age-associated, amyloid deposition occurs in foot and ankle (F&A) tissues has not previously been investigated. In this study we assessed the nature and frequency of F&A amyloid deposition and determined whether it is associated with age and/or specific articular/periarticular F&A lesions. METHODS Histological sections of twenty five normal F&A articular/periarticular tissues (16-71 years) and a range of F&A lesions were stained by Congo Red. The amyloid protein was identified by immunohistochemistry and type of matrix glycosaminoglycans determined by Alcian Blue (critical electrolyte concentration) histochemistry. RESULTS Amyloid deposits were found in the joint cartilage and capsule of 3/25 normal specimens (57, 62 and 78 years). Amyloid deposits were small, contained transthyretin, and found in areas of matrix degeneration associated with the presence of highly sulphated glycosaminoglycans. In patients older than 47 years, small amyloid deposits were noted in some F&A lesions, including osteoarthritis, Charcot arthropathy, bursa, ganglion, chondrocalcinosis, gout, calcific tendonitis and Achilles tendonitis. CONCLUSION Small localised amyloid deposits in F&A tissues contain transthyretin and occur in areas of matrix degeneration associated with the presence of highly sulphated glycosaminoglycans; these deposits are age-associated and, although seen more commonly in some F&A lesions, are small and unlikely to be of pathogenic significance.

Abstract
The application of extracellular matrix (ECM) sheets without a scaffold is not extensively reported in bone regenerative medicine. The aim of the present study was to demonstrate that an osteogenic ECM sheet (OECMS) can retain ECM integrity and growth factors to enhance bone formation in a rat non-union model. OECMS was produced from osteogenic cell sheets (OCS). Collagen and growth factor [bone morphogenetic protein 2 (BMP-2), vascular endothelial growth factors (VFGFs), basic fibroblast growth factor (bFGF) and transforming growth factor β1 (TGF-β1)] concentrations in the OECMS were quantified by enzyme-linked immunosorbent assay (ELISA). Next, hydroxyapatite (HA) constructs combined with OECMSs were implanted subcutaneously into the rats' backs to evaluate their osteoinductive capacity by histological evaluation. In addition, OECMSs were implanted in a rat femoral non-union model. 18 male Fischer 344 inbred rats were divided into OECMS and control groups. Fracture healing was evaluated by radiological and histological analyses at 2, 5 and 8 weeks and biological analysis at 8 weeks. Collagen I and growth factors were retained in the OECMSs. Osteoid formation was identified in the HA combined with OECMS at 4 weeks. Enhanced bone regeneration at the non-union of the OECMS group was confirmed at 5 and 8 weeks. Biomechanical testing revealed a significantly higher maximum bending load in the OECMS group as compared to the control group at 8 weeks. The results demonstrated that OECMS retained BMP-2 and TGF-β1 and high osteoinductive and osteoconductive capacity. As such, OECMS represents a potential new scaffold-free material for bone tissue engineering.
