Abstract
BACKGROUND Although changes in the gait biomechanics during pregnancy are known to occur, it is unclear whether they return to their original state after childbirth. RESEARCH QUESTION The objective of the current systematic review is to summarize existing literature reporting the biomechanical characteristics of gait in postpartum women and to identify knowledge gaps that calls for future investigations in this population. METHODS Relevant articles were selected using MEDLINE (PubMed), Scopus (Elsevier), Embase (Elsevier), and Web of Science (Clarivate Analytics). Articles were included if they met the following criteria: They must (1) include postpartum women, (2) report measures related to three-dimensional (3D) kinematics and/or kinetics, (3) have been published after 1990, and (4) have been published in English. RESULTS AND SIGNIFICANCE The current systematic review included a total of 14 articles, five of which compare the data from postpartum women with nulliparous women or pre-pregnancy data. We observed that gait biomechanics changes of postpartum women could persist for more than 5 years after the childbirth. This review provides novel viewpoints on the biomechanics of postpartum women's gait and recommendations for future studies to fully understand these changes and improve postpartum women's physical and mental wellbeing.

Abstract
Hybrids can express traits plastically, enabling them to occupy environments that differ from parental environments. However, there is insufficient evidence demonstrating how phenotypic plasticity in specific traits mediates hybrid performance. Two parental ecotypes of Imperata cylindrica produce F1 hybrids. The E-type in wet habitats has larger internal aerenchyma than the C-type in dry habitats. This study evaluated relationships between habitat utilisation, aerenchyma plasticity, and growth of I. cylindrica accessions. We hypothesize that plasticity in expressing parental traits explains hybrid establishment in habitats with various soil moisture conditions. Aerenchyma formation was examined in the leaf midribs, rhizomes and roots of two parental ecotypes and their F1 hybrids in their natural habitats. In common garden experiments, we examined plastic aerenchyma formation in leaf midribs, rhizomes and roots of natural and artificial F1 hybrids and parental ecotypes and quantified vegetative growth performance. In the natural habitats where soil moisture content varied widely, the F1 hybrids showed larger variation in aerenchyma formation in rhizomes than their parental ecotypes. In the common garden experiments, F1 hybrids showed high plasticity of aerenchyma formation in rhizomes, and their growth was similar to that of C-type and E-type under drained and flooded conditions, respectively. The results demonstrate that F1 hybrids of I. cylindrica exhibit plasticity in aerenchyma development in response to varying local soil moisture content. This characteristic allows the hybrids to thrive in diverse soil moisture conditions.

Abstract
Brigatinib-based therapy was effective against osimertinib-resistant EGFR C797S mutants and is undergoing clinical studies. However, tumor relapse suggests additional resistance mutations might emerge. Here, we first demonstrated the binding mode of brigatinib to the EGFR-T790M/C797S mutant by crystal structure analysis and predicted brigatinib-resistant mutations through a cell-based assay including N-ethyl-N-nitrosourea (ENU) mutagenesis. We found that clinically reported L718 and G796 compound mutations appeared, consistent with their proximity to the binding site of brigatinib, and brigatinib-resistant quadruple mutants such as EGFR-activating mutation/T790M/C797S/L718M were resistant to all the clinically available EGFR-TKIs. BI-4020, a fourth-generation EGFR inhibitor with a macrocyclic structure, overcomes the quadruple and major EGFR-activating mutants but not the minor mutants, such as L747P or S768I. Molecular dynamics simulation revealed the binding mode and affinity between BI-4020 and EGFR mutants. This study identified potential therapeutic strategies using the new-generation macrocyclic EGFR inhibitor to overcome the emerging ultimate resistance mutants.

Abstract
PURPOSE/OBJECTIVE(S) 3D dose distribution measurement is crucial for precise radiotherapy. Radiation-excited fluorescence imaging has potential for the 3D dosimetry with high spatial resolution, but multiple fluorescence images from different view-angles are required for analytical reconstruction techniques. Furthermore, the imaging data are contaminated by anisotropic Cherenkov light emission and statistical noise. This project aims to establish a novel deep learning-based model to predict 3D dose distributions from a single-view 2D fluorescence image while simultaneously removing the adverse effects of Cherenkov signals and other noises. MATERIALS/METHODS A total of 124 single-aperture static photon beams were delivered to an acrylic tank containing 1 g/L quinine hemisulfate water solution with varying aperture shapes and collimator angle. The emitted optical signals were detected by a low-cost CMOS camera for 20 seconds, and image pre-processing was performed to obtain input 2D fluorescence images with 0.3 × 0.3 mm spatial resolution. 3D back-projected dose distribution images were also calculated from the input fluorescence images. Ground-truth of 3D dose distributions and 2D field map images were obtained from a clinical treatment planning system with 1.4 × 1.4 × 1.4 mm spatial resolution. The proposed deep learning-based dose reconstruction method involved 3 steps. First, 2D fluence map images at the bottom plane of the tank were predicted from the fluorescence images by using a customized convolutional neural network (CNN). Second, the predicted fluence map images were transformed into the 2D field map images on the isocenter plane by applying perspective transformation. Finally, 2D dose distributions at a given radiological depth were calculated by using the predicted field map images, the back-projected dose distribution images, and the radiological depth value as inputs of a shallow CNN. Both CNN models were trained separately, and the 3D dose distributions were predicted by concatenating the output 2D dose distributions at various radiological depths. RESULTS The proposed CNN model yielded accurate 2D field map images. Averaged Dice similarity coefficient and mean absolute error of the field maps in the test data was 92.0% ± 4.6% and 0.0132 ± 0.0113, respectively. Moreover, our deep learning-based approach was able to predict accurate 3D dose distributions from the 2D fluorescence images. Mean squared error and averaged 3D gamma passing ratio (3%/3mm) were 9.55 mGy ± 6.8 mGy and 86.3% ± 9.86%, respectively. CONCLUSION Theproposed deep learning-based method calculated accurate 3D dose distributions from a single-view 2D fluorescence image. Since this technique require only a single CMOS camera image and fluorescent material, it can be readily used for any external radiotherapy modalities, including SRS/SBRT with small fields. This method is useful for acquiring 3D dose distribution data for precise dose verification within a few seconds.

Abstract
Abstract
Introduction: In vivo, tumor microenvironments consist of not only cancer cells but also extracellular matrix and stromal tissues, such as fibroblasts, blood vessels, and so on. The interactions between cancer cells and stromal tissue have been reported to affect the behavior of cancer cells. So that ex vivo model recapturing the tumor microenvironment is needed to evaluate the efficacy of drugs under the condition mimicking the patient tumor tissue. Here, we developed the unique tissue engineering technique, which easily enables the construction of cell - stacked three dimensional (3D) tissue, and co-culture of 3D stromal tissues and patient-derived cancer cells (PDCs). We investigated drug sensitivity in conventional 2D culture, our 3D co-cultured model and in vivo tumor.
Methods: Fibroblasts and vascular endothelial cells were suspended in a buffer solution containing heparin and collagen to support cell aggregation. The heparin/collagen-treated cells were seeded in culture-inserts in over-confluent manner, and 3D layered stromal tissue called were constructed. PDCs established from colorectal cancer (CRC) and non-small cell lung cancer (NSCLC) patients in the Cancer Institute Hospital of JFCR were co-cultured with the 3D stromal tissue. The 3D co-cultured model applied to drug screening, and the results were compared with those of 2D culture model. In vivo drug evaluations were performed with the compounds in which marked differences were observed between 2D and 3D models.
Results: In our 3D model, drug sensitivities to most of the tested compounds tended to be decreased in comparison with those in 2D culture condition. Interestingly, a part of drugs did not effective in 2D showed marked tumor growth inhibition in our 3D model. The compounds that showed favorable efficacy in 3D rather than 2D in multiple PDCs were accounted for about 5% of tested compounds. At least half of these drugs showed significant tumor growth suppression or tumor regression in vivo. On the contrary, in the case of drug sensitivities were considerably fallen in our 3D model, most of the evaluated compounds represented almost no anti-tumor effect in vivo. Results from gene and protein expression analyses supported that cancer cells co-cultured in our 3D stromal tissue have some similar profiles to in vivo tumor rather than 2D culture condition.
Conclusion: Our study proposed the unique 3D co-cultured tumor model. The model may enable more accurate drug screening reflecting the in vivo circumstances. Further studies are needed to confirm the model’s predictability of clinical outcomes.

Abstract
BACKGROUND The Masquelet method has become increasingly popular for the treatment of bone defects in recent years. In this method, an induced membrane (IM) with abundant blood circulation, stem cells, and osteogenesis-promoting factors is formed by implanting bone cement during the first surgery. This IM stimulates bone formation in the bone defect after implantation of the bone graft during the second surgery. However, the Masquelet method requires two surgeries and thus a longer treatment period. In the present study, we investigated whether bone defects could be reconstructed in a single surgery by introducing a vascular bundle into the bone defect as an alternative to the IM, in addition to bone grafting. METHODS Thirty-six 12-week-old female Sprague-Dawley rats were used. After creating a 5-mm long bone defect in the femur, a mixture of autologous and artificial bone was grafted into the defect, and a saphenous arteriovenous vascular bundle was introduced. The animals were divided into three groups: the control group (bone defect only), the BG group (bone grafting only), and the BG + V group (bone grafting + vascular bundle introduction). After surgery, radiological and histological evaluations were performed to assess osteogenesis and angiogenesis in bone defects. RESULTS In the BG + V group, significant bone formation was observed in the bone defect on radiological and histological evaluations, and the amount of bone formation was significantly higher than that in the other two groups. Furthermore, cortical bone continuity was observed in many specimens in the BG + V group. On histological evaluation, the number of blood vessels was also significantly higher in the BG + V group than in the other two groups. CONCLUSION Our results suggest that the introduction of a vascular bundle in addition to bone grafting can promote bone formation in bone defects and allow for complete bone defect reconstruction in a single surgery.

Abstract
We investigated serum total antibody titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein receptor-binding domain after BNT162b2 mRNA vaccination against coronavirus disease 2019 (COVID-19) in Japanese patients taking various immunosuppressive medications for rheumatic disease. In 212 outpatients with rheumatic diseases at Kagawa University Hospital and 43 healthy volunteers (controls), all of whom had received 2 doses of BNT162b2 vaccine, serum antibody titers of SARS-CoV-2 spike protein were analyzed at least 14 days after the second dose. Many of the patients were taking immunosuppressive agents to manage their rheumatic disease. The antibody titers against SARS-CoV-2 spike protein in these patients were significantly lower than those in controls. The analysis of therapeutic agents revealed that the antibody titers in patients treated with rituximab were much lower than those in controls. In patients treated with tacrolimus, baricitinib, azathioprine, mycophenolate mofetil, abatacept, tumor necrosis factor inhibitors, cyclosporine, interleukin-6 inhibitors, methotrexate, or glucocorticoids, antibody titers were moderately lower than those of controls. Interleukin-17 and interleukin-23 inhibitors did not impair the humoral response. In addition, the combination of methotrexate with various immunosuppressive agents reduced titers, although not significantly. In Japanese patients with rheumatic disease, many immunosuppressants impaired the immune response to the BNT162b2 vaccine. The degree of decline in antibody titers differed according to immunosuppressant. When used concomitantly with other immunosuppressants, methotrexate may impair the immune response to the BNT162b2 vaccine. However, immunomodulatory treatments such as interleukin-17 and -23 inhibitors may not attenuate this response in patients with rheumatic disease.

Abstract
Background The aim of this study was to investigate factors influencing postpartum physical activity (PA), taking into consideration psychosocial perceptions during the coronavirus disease 2019 (COVID-19) pandemic by comparing health-related quality of life (HRQoL) scores. Methods A web-based cross-sectional survey of 787 postpartum women was conducted between March and October 2021. After applying the exclusion criteria, 590 women were analyzed. The International Physical Activity Questionnaire Short Form, was used to assess the level and amount of PA. The Short Form-12 Health Survey version 2 (SF-12v2) was used to measure HRQoL. Logistic regression analyses were used to determine whether sociodemographic factors and psychosocial perceptions during the COVID-19 pandemic were associated with the level of PA. Based on the current national guidelines for exercise in Japan, respondents were classified by weekly PA level as an Inactive group and an Active group to assess the influence of PA on HRQoL. Results Mean total PA was 19.3 total metabolic equivalents hour/week, and the prevalence of an inactive lifestyle was 45.9% among respondents. Each year of age was associated with an odds ratio (OR) of 0.92 (95% CI 0.87–0.97) for becoming physical inactivity during postpartum. Factors positively associated with more active levels were greater number of days for delivery (OR = 1.00; 95% CI 1.00–1.01), multiparity (OR = 1.50; 95% CI 1.00–2.23), having someone to talk about childcare and the individual’s partner (OR = 2.04; 95% CI 0.96–4.36) and not having anxiety symptoms (OR = 0.58; 95% CI 0.35–0.97). The Active group had significantly higher HRQoL scores than the Inactive group in the following scales: physical component summary (p < 0.001), mental component summary (p = 0.041). Conclusions The influential factors for postpartum PA level were younger age, longer duration after childbirth, multiparity and not having anxiety symptoms, which correlated positively with PA. The presence of someone with whom can talk to about childcare and partner issues was associated with the maintenance of higher PA among postpartum women, suggesting that factor as a positive influence on PA under unsettled conditions.

Abstract
In the surgical management of Dupuytren contracture (DC), Y-V plasty (YV) and Z-plasty (ZP) are techniques often used for skin extension. However, achieving sufficient skin extension with these procedures alone is often difficult. Therefore, we addressed this issue with an adjunctive digito-lateral flap (DLF) and report the clinical results of the surgery using a DLF in addition to YV and ZP. Fifteen patients with DC (15 affected fingers) underwent partial fasciectomy using a DLF in addition to YV or ZP, and early active finger extension training was performed immediately after the operation. The flap survival rate, preoperative and postoperative extension angle, Tonkin contracture improvement (TCI) rate, and Tubiana staging grades were evaluated. The contracture sites were at 4 proximal interphalangeal (PIP) and 3 metacarpophalangeal (MP) joints of the little finger and 4 PIP and MP joints each of the ring and little fingers. All the flaps survived, and the extension angle improved at the final observation from a preoperative mean of -45° to -3° and -55° to 5° for the PIP and MP joints, respectively. One patient with PIP joint contracture treated in the early stage of the study experienced a persistent 5° limitation of extension, even though the TCI rate was satisfactory (91.9%) and the outcome was "good." Full extension of the joints was achieved in 15 patients, in whom the TCI rate was 100% and the outcome was "very good." This technique was able to solve 3 important steps to achieve full extension: intraoperatively, wound closure, and rehabilitation. We attained and maintained long-term full extension intraoperatively and immediately after surgery and obtained very good treatment results, as shown in this study. In conclusion, highly favorable clinical outcomes were achieved through the combination of a DLF with YV and ZP. Skin extension with a DLF is a useful surgical technique for DC.

Abstract
Objective To investigate the serum total antibody (immunoglobulin M and immunoglobulin G) titre against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein receptor-binding domain following BNT162b2 messenger ribonucleic acid (mRNA) coronavirus disease 2019 (COVID-19) vaccination in Japanese rheumatic disease patients undergoing immunosuppressive therapy. Methods The serum antibody titre against SARS-CoV-2 spike protein was analysed in 123 outpatients with rheumatic diseases at Kagawa University Hospital and 43 healthy volunteers who had received 2 doses of the BNT162b2 mRNA vaccine with at least 14 days elapsing since the second dose. Results The antibody titre in rheumatic disease patients was significantly lower than that in healthy subjects (p<0.0001). The antibody titres of the 41 patients who received biologics or Janus kinase inhibitors and the 47 patients who received conventional immunosuppressive agents were significantly lower than those of the 35 patients who did not receive immunosuppressive agents (p<0.0001 and p<0.0001, respectively). In addition, the mean antibody titre of the 43 patients on methotrexate was significantly lower than that of the 80 patients not on methotrexate (p=0.0017). Conclusion Immunogenicity to the BNT162b2 mRNA COVID-19 vaccine in rheumatic disease patients was found to be reduced under immunosuppressive treatment. In particular, methotrexate seems to be associated with a decreased antibody response.

Abstract
The use of volar locking plates (VLPs) for distal radius fractures has remarkably improved clinical outcomes; however, there are some reports of delayed recovery of grip strength. Since January 2019, we have been conducting an early and proactive grip strength training program (EGTP). In this program, 20 minutes of grip strength training-using a gripper with a load of 0.7 kg-was initiated from 2 weeks after surgery; the load was then gradually increased. From 6 weeks postsurgery, daily home grip strength training was performed using a gripper with a load of 5 kg, provided to the patient.We investigated whether the introduction of the EGTP could lead to earlier recovery of grip strength. We also examined whether the EGTP caused postoperative correction loss at the fractured site, or contributed to the early improvement of wrist function.Thirty-nine patients who underwent surgery using VLPs for distal radius fractures were included in this study; 20 followed the EGTP (EGTP group) and 19 patients did not (NGTP group). For these patients, grip strength and range of motion of the wrist joint were evaluated both 3 and 6 months postoperatively. The Quick Disabilities of the Arm, Shoulder, and Hand (qDASH) scores were also evaluated 6 months postoperatively. Additionally, corrective losses of radial inclination (RI), palmar tilt (PT), and ulnar variance (UV)-occurring from immediately postsurgery to 6 months after surgery-were evaluated.At both 3 and 6 months postoperatively, the grip strength of the EGTP group was significantly higher than that of the NGTP group. Regarding range of motion, only palmar flexion was significantly improved in the EGTP group at 3 months postoperatively. Conversely, no differences in corrective losses of RI, PT, and UV, or in qDASH scores, were observed between the two groups.The results of this study suggest that the EGTP can provide early recovery of grip strength and palmar flexion of the wrist without causing corrective loss at the fracture site.

Abstract
BACKGROUND In recent years, advances in pharmacotherapy for rheumatoid arthritis (RA) have dramatically improved the control of disease activity. However, a significant number of patients still develop forefoot deformity. The purpose of this study was to investigate the results of more than 20 years' follow-up of metatarsal neck shortening oblique osteotomy (SOO) for forefoot deformity in patients with RA. METHODS The metatarsal neck SOO was performed on 163 feet in 108 patients between January 1985 and December 1996 in the authors' hospital. For the patients, who met the survey criteria, an observational study was performed clinically and radiologically at the baseline and at more than 20 years after surgery. RESULTS A retrospective cohort study was conducted on 36 feet in 22 patients, all of whom were female, and the mean age at surgery was 45.6 (35.0-63.0) years old. The follow-up period was 25.1 (21.0-31.0) years. The presence of painful callosities in the surgically treated feet without revised surgeries decreased from 32 feet (100%) to 4 feet (12.5%) at the last follow-up with mild pain that did not cause any footwear problems. Re-osteotomy at the metatarsal of the lessor toe was performed on four feet in two patients. Radiologically, among 128 toes without revised surgeries, 85% were able to have the joint space preserved, and 89% maintained a pain-free condition without any recurrence of deformity. The mean total Japanese Society for Surgery for the Foot (JSSF) RA foot and ankle score was 64.0/100, and the visual analogue scale (VAS) of overall satisfaction was 62 (0: dissatisfied, 100: highly satisfied). The overall satisfaction had a positive correlation with calcaneal pitch and negative correlation with joint space narrowing at the talocrural joint. CONCLUSIONS Metatarsal neck SOO appeared to be effective for patients with RA. The deformity was corrected and retained for a long time.

Abstract
The magnetic ground states ofR2Ru2O7andA2Ru2O7withR= Pr, Gd, Ho, and Er, as well asA= Ca, Cd are predicted devising a combination of the cluster-multipole (CMP) theory and spin-density-functional theory (SDFT). The strong electronic correlation effects are estimated by the constrained-random-phase approximation (cRPA) and taken into account within the dynamical-mean-field theory (DMFT). The target compounds feature d-orbital magnetism on Ru4+and Ru5+ions forRandA, respectively, as well as f-orbital magnetism on theRsite, which leads to an intriguing interplay of magnetic interactions in a strongly correlated system. We find CMP + SDFT is capable of describing the magnetic ground states in these compounds. The cRPA captures a difference in the screening strength betweenR2Ru2O7andA2Ru2O7compounds, which leads to a qualitative and quantitative understanding of the electronic properties within DMFT.

Abstract
This article introduces our lasso loop technique (LLT) using a bioabsorbable thread for the treatment of intra-articular distal radius fractures with displaced dorsal bone fragment containing articular surface (DBF). We also examined whether the articular gap is sufficiently reduced and maintained by the LLT, along with the results of other radiological and clinical evaluations. We retrospectively reviewed 19 patients who underwent LLT for intra-articular distal radius fracture with a displaced DBF. Patient radiographic images and medical records were used to investigate radiological characteristics, symptoms, physical findings, and the Quick Disabilities of the Arm, Shoulder, and Hand scores. Sagittal-view computed tomography showed that the mean preoperative articular gap was 2.6 mm, but the gap was reduced by LLT, and the gap immediately postoperatively was <1.0 mm in all patients. No re-displacement of the DBF was evident from immediately postoperatively to 6 months postoperatively. Postoperatively, no losses of correction in palmar tilt, radial inclination, or ulnar variance were seen in the evaluation of plain radiographs, and satisfactory joint range of motion, grip strength, and the Quick Disabilities of the Arm, Shoulder, and Hand score were obtained. No significant complications due to LLT were observed. LLT appears to offer a simple and effective procedure to reduce displaced DBF with little risk of complications. LLT may become a useful option in the treatment of intra-articular distal radius fractures with displaced DBF.

Abstract
BACKGROUND/AIM Advanced undifferentiated pleomorphic sarcoma (UPS) has a poor prognosis and there are few treatments that can improve overall survival. Recently, Rapalink-1, a third-generation mammalian target of rapamycin (mTOR) kinase inhibitor, has been developed and shown to be effective against other tumours. However, mTOR inhibitors have been shown to induce autophagy and resistance to anti-cancer drugs. This study aimed to investigate the antitumor effects of Rapalink-1 with an autophagy inhibitor. MATERIALS AND METHODS The antitumor effect of Rapalink-1 and/or hydroxychloroquine in three UPS cell lines was examined via cell viability analysis, western blotting, flow cytometry and immunofluorescence. RESULTS Rapalink-1 decreased cell proliferation and inhibited the PI3K/mTOR pathway. Combined treatment with Rapalink-1 and hydroxychloroquine enhanced the antitumor effect compared to treatment with Rapalink-1 alone by blocking the autophagy-inducing effect of mTOR inhibitors. CONCLUSION Combined treatment with Rapalink-1 and hydroxychloroquine may be used as a potential therapeutic agent against UPS.

Abstract
The present study aims to evaluate changes in plantar pressure distribution after joint-preserving surgery for rheumatoid forefoot deformity. A retrospective study was performed on 26 feet of 23 patients with rheumatoid arthritis (RA) who underwent the following surgical combination: modified Mitchell's osteotomy (mMO) of the first metatarsal and shortening oblique osteotomy of the lateral four metatarsals. Plantar pressure distribution and clinical background parameters were evaluated preoperatively and one year postoperatively. A comparison of preoperative and postoperative values indicated a significant improvement in the visual analog scale, Japanese Society for Surgery of the Foot scale, and radiographic parameters, such as the hallux valgus angle. A significant increase in peak pressure was observed at the first metatarsophalangeal joint (MTPJ) (0.045 vs. 0.082 kg/cm2; p < 0.05) and a significant decrease at the second and third MTPJs (0.081 vs. 0.048 kg/cm2; p < 0.05, 0.097 vs. 0.054 kg/cm2; p < 0.05). While overloading at the lateral metatarsal heads following mMO has been reported in previous studies, no increase in peak pressure at the lateral MTPJs was observed in our study. The results of our study show that this surgical combination can be an effective and beneficial surgical combination for RA patients with mild to moderate joint deformity.

Abstract
ABSTRACT We report the clinical results and problems of combined administration of rifampicin, ethambutol, and clarithromycin (REC) for the treatment of Mycobacterium avium complex (MAC) infection of the hand (hand MAC).Participants included 7 patients with hand MAC. After resection of the infected lesion, REC was prescribed for 12 months. For these patients, the site of infection, clinical course after initiation of REC, adverse drug effects (ADEs), and incidence of recurrence were evaluated.Sites of infection were the flexor tenosynovium in 5 patients, extensor tenosynovium in 1 patient, and both flexor and extensor tenosynovium in 1 patient. ADEs of REC occurred in 5 patients, and included visual disturbance caused by ethambutol in 2 patients, liver function abnormality caused by rifampicin in 2 patients, and fever with diarrhea caused by rifampicin in 1 patient. For 2 of these 5 patients, desensitization therapy was applied and REC was able to be reinstated. In the remaining 3 patients, the causative drugs were discontinued and levofloxacin, a new quinolone, was administered. Complete healing was achieved in 5 patients, and recurrence was observed in 2 patients. These 2 patients with recurrence included 1 patient in whom REC was completed and 1 patient in whom REC therapy was modified due to ADE.REC provided relatively good clinical results as a treatment for hand MAC. However, recurrences were observed even after the completion of REC and the use of an alternative drug. Optimal duration of REC and appropriate alternative drugs need to be identified in the future.

Abstract
AIM Aspergillus niger S17-5 produces two alkylitaconic acids, 9-hydroxyhexylitaconic acid (9-HHIA) and 10-hydroxyhexylitaconic acid (10-HHIA), which have cytotoxic and polymer building block properties. In this study, we characterized the production of 9-HHIA and 10-HHIA by addition of their expected precursor, caprylic acid, to a culture of A. niger S17-5, and demonstrated batch fermentation of 9-HHIA and 10-HHIA in a jar fermenter with DO-stat. METHODS AND RESULTS Production titres of 9-HHIA and 10-HHIA from 3% glucose in a flask after 25 days cultivation were 0·35 and 1·01 g l-1 respectively. Addition of 0·22 g l-1 of caprylic acid to a suspension of resting cells of A. niger S17-5 led to 32% enhancement of total 9-HHIA and 10-HHIA production compared to no addition. No enhancement of the production of 9-HHIA or 10-HHIA by the addition of oxaloacetic acid was observed. Addition of caprylic acid to the culture at mid-growth phase was more suitable for 9-HHIA and 10-HHIA production due to less cell growth inhibition by caprylic acid. DO-stat batch fermentation with 3% glucose and 14·4 g l-1 of caprylic acid in a 1·5 l jar fermenter resulted in the production titres of 9-HHIA and 10-HHIA being 0·48 and 1·54 g l-1 respectively after 10 days of cultivation. CONCLUSIONS Addition of caprylic acid to the culture of A. niger S17-5 enhances 9-HHIA and 10-HHIA production. SIGNIFICANCE AND IMPACT OF THE STUDY These results suggest that 9-HHIA and 10-HHIA are synthesized with octanoyl-CoA derived from caprylic acid, and that the supply of octanoyl-CoA is a rate-limiting step in 9-HHIA and 10-HHIA production. To the best of our knowledge, this is the first report regarding the fermentation of naturally occurring itaconic acid derivatives in a jar fermenter.

Abstract
Abstract
Background
A silent cerebral event (SCE), detected by brain magnetic resonance imaging (MRI), is defined as an acute new brain lesion without clinically apparent neurological deficit, and is frequently observed after catheter ablation in atrial fibrillation (AF) patients. Although the small number of SCEs does not cause neurocognitive dysfunction, the greater volume and/or larger number of SCE lesions are reportedly related to neuropsychological decline; SCE incidence may be a surrogate marker for the potential thromboembolic risk. Thus, strategies to reduce SCEs would be beneficial. Uninterrupted oral anticoagulation strategy for peri-procedural period reportedly reduced the risk of SCEs, but the incidence hovers at 10% to 30%. We sought factors associated with SCEs during catheter ablation for AF in patients with peri-procedural uninterrupted oral anticoagulation (OAC) therapy.
Methods
AF patients undergoing catheter ablation were eligible (n=255). All patients took non-vitamin K antagonist oral anticoagulants (NOACs) or vitamin K antagonist (VKA) for peri-procedural OAC (>4 weeks) without interruption during the procedure. Brain MRI was performed within 2 days after the procedure to detect SCEs. Clinical characteristics and procedure-related parameters were compared between patients with and without SCEs.
Results
SCEs were detected in 59 patients (23%, SCE[+]) but not in 196 patients (77%, SCE[-]). Average age was higher in SCE[+] than SCE[-] (66±10 years vs. 62±12 years, p<0.05). Persistent AF prevalence, CHADS2/CHA2DS2-VASc scores, and serum NT-ProBNP levels increased in SCE[+] vs. SCE[-]. In transthoracic/transesophageal echocardiography, left-atrial dimension (LAD) was larger and AF rhythm/spontaneous echo contrast were more frequently observed in SCE[+] than SCE[-]. SCE[+] had lower initial activated clotting time (ACT) before unfractionated heparin (UFH) injection and longer time to reach optimal ACT (>300 sec) before trans-septal puncture than SCE [-]. In multivariate analysis, LAD, initial ACT before UFH injection, and time to reach optimal ACT were predictors for SCEs.
Conclusions
LAD and intra-procedural ACT kinetics affect SCEs during the procedure in patients with uninterrupted OAC for AF ablation. Shortening time to achieve optimal ACT during the procedure may reduce the risk of SCEs.

Abstract
BACKGROUND We have developed a prefabricated vascularized allo-bone graft (PVAG) by implanting the saphenous vascular bundles of recipient rats into transplanted donor bones in a flow-through manner. We previously demonstrated that the angiogenetic and bone formative abilities of the PVAG are stimulated by the addition of a basic fibroblast growth factor (bFGF)-containing hydroxyapatite/collagen (HAp/Col). This study aimed to demonstrate that the bone union ability of the PVAG is similarly stimulated by the bFGF-containing HAp/Col composite. METHODS Sprague-Dawley donor rats (n = 32) and Wistar recipient rats (n = 32) were used in this study. The PVAG was fixed to the femur of the recipient rat using K-wire (dimeter: 0.7 mm) pinning, followed by suturing with a 4-0 nylon suture. Recipients were divided into four groups: with or without vascular bundles, and with or without bFGF-containing HAp/Col. Rats were sacrificed 6 weeks after transplantation, and bone union, bone resorption, and angiogenesis were radiologically and histologically evaluated. RESULTS Radiological analysis revealed a significant increase in callus formation and union rate, while histological analysis showed a significant increase in bone formation and angiogenesis in the group treated with both vascular bundles and bFGF. Bone resorption did not significantly increase in any of the evaluated groups. CONCLUSION Osteogenic cells, osteoconductive scaffolds, growth factors, and mechanical environment are known to be important factors in the process of fracture healing. The PVAG developed herein contains osteogenic cells, osteoconductive scaffolds, and growth factors. In addition, the PVAG is rigidly fixed to the fracture site, providing a stable mechanical environment. Together, these four factors contributed to a good bone union. Furthermore, this method did not promote bone resorption. Thus, the addition of a vascular bundle and bFGF-containing HAp/Col makes it possible to create an ideal vascularized allo-bone graft for the reconstruction of massive bone defects.

Abstract
OBJECTIVE Digital joints affected by rheumatoid arthritis often have severe deformity and/or dislocation, and arthrodesis in a functional position is required. METHODS Arthrodesis was performed using intraosseous wiring (modified Lister's method) from January 2011 to December 2015, and we investigated the union rate, postoperative complications, and patient satisfaction with the operation at the final follow-up. The DASH score, grip power, and pinch power were also investigated before the operation and at the final follow-up. RESULTS Arthrodesis was performed for 90 digital joints in 56 patients. Bone union was obtained in 85 of 89 joints (96%). Wire removal was needed due to subcutaneous protrusion in 20 joints and superficial infection in five joints. The mean preoperative DASH score of 50.5 improved to 45.2 at the final follow-up. The pulp pinch power of the index fingers through the little fingers changed significantly. In the questionnaire regarding the operated digit using a visual analogue scale (VAS, 0 [worst] to 100 [best]), the overall satisfaction was 70. CONCLUSION With this approach, we achieved painless stability as well as deformity correction. A restored prehensile pattern and improvement in the activities of daily life can thus be expected after surgery.

Abstract
Exposure to prenatal stress increases offspring risk for long-term neurobehavioral impairments and psychopathology, such as Attention Deficit Hyperactivity Disorder (ADHD). Epigenetic regulation of glucocorticoid pathway genes may be a potential underlying mechanism by which maternal conditions 'program' the fetal brain for downstream vulnerabilities. The present study aims to investigate whether mRNA expression of glucocorticoid pathway genes in the placenta predict offspring negative affect during early childhood (between 6 and 24 months). Participants include 318 mother-child dyads participating in a longitudinal birth cohort study. Placental mRNA expression of glucocorticoid pathway genes (HSD11B1, HSD11B2, NR3C1, NCOR2) were profiled and negative affect traits of the offspring were measured at 6, 12, 18, and 24 months. HSD11B1 mRNA expression significantly predicted negative affect (β = -.09, SE = .04; p = .036), and Distress to Limitations trajectories (β = -.13, SE = .06; p = .016). NCOR2 mRNA expression significantly predicted Distress to Limitations (β = .43, SE = .21; p = .047), and marginally predicted Sadness trajectories (β = .39, SE = .21; p = .068). HSD11B2 and NR3C1 did not predict trajectories of Negative Affect or subscale scores. Infant negative affect traits were assessed via maternal self-report, and deviated from linearity across follow-up. mRNA expression of glucocorticoid pathway genes in the placenta may be a potentially novel tool for early identification of infants at greater risk for elevated negative affect. Further study is needed to validate the utility of mRNA expression of glucocorticoid pathway genes in the placenta.

Abstract
Objectives: To evaluate changes in radiographic findings and plantar pressure distribution after rheumatoid forefoot surgery.Methods: This study was performed on patients with rheumatoid arthritis (RA) who underwent Swanson implant arthroplasty for the 1st metatarsophalangeal (MTP) joint combined with shortening oblique osteotomy at the 2nd through 5th metatarsal necks (group Sw, 55 feet). The following two groups were used as controls: group NS, consisting of 75 feet in RA patients without scheduled forefoot surgery, and group HC, consisting of 24 feet in healthy female subjects. Plantar pressure distribution, and radiographic findings of hallux valgus angle, the angle between the metatarsal bones, talocalcaneal angle, calcaneal pitch angle and calcaneo-first metatarsal angle (CFMA) were measured pre- and one year postoperatively. Peak pressure was measured in nine sections.Results: Calcaneal pitch angle decreased and CFMA increased in group Sw. Peak pressure at the 1st interphalangeal joint (IP) and the 2nd and 3rd MTPs in group Sw decreased, while that at midfoot increased.Conclusion: While the clinical outcome in group Sw was favorable, postoperative longitudinal arch decreased. Postoperative peak pressure at the 2nd through 5th MTPs was comparable with that in group NS; however, it was significantly lower than that in group HC.

Abstract
Prenatal famine, resulting in intrauterine malnutrition, impacts offspring psychopathology later in adulthood. In addition, the specific impact of intrauterine malnutrition of different psychopathology differs by the timing of the exposure. Using a meta-analysis, the current study assessed the specific risk of developing affective, psychotic, and personality disorders. Studies were identified using PubMed and PsycINFO. Studies met the following criteria for inclusion in the analysis: availability in peer-reviewed English journals, use of human subjects, prenatal exposure to famine, and psychopathology in adulthood defined by diagnostic criteria as an outcome. Fixed effect relative risks (RRs) were calculated for affective, psychotic, and personality domains. Furthermore, timing of exposure was assessed as an effect modifier in our analysis, defined by the index trimester at the height of famine. Our meta-analysis found that adults exposed in utero during the 1st trimester were at a significant increased risk of psychotic disorders (RR=1.46, 95% CI=1.08, 1.97, p=0.014), and personality disorders (RR=2.31, 95% CI=1.36, 3.92, p=0.002). Those exposed during the 2nd trimester were at a significant increased risk of affective disorders (RR=1.45, 95% CI=1.22, 1.72, p<0.0001), and psychotic disorders (RR=1.46, 95% CI=1.13, 1.89, p=0.004). Similarly, those exposed in the 3rd trimester were at a significant increased risk of affective disorders (RR=1.33, 95% CI=1.13, 1.57, p=0.0001), and psychotic disorders RR=1.47, 95% CI=1.10, 1.97, p=0.010). Our findings suggest that there is differential risk across the different domains of psychopathology by trimester of exposures. This meta-analysis underscores the need for further investigation into the mechanisms underlying prenatal maternal nutrition and offspring psychopathology where magnitude of elevated risk differs by the exposure timing during pregnancy.

Abstract
Abstract
Background
There is increasing evidence to use direct oral anticoagulants (DOACs) in atrial fibrillation (AF) ablation. Uninterrupted use of DOACs is recommended for peri-procedural anticoagulation; the ways of choosing and/or using DOACs depend on physicians' decisions and preferences. Uninterrupted dabigatran (DAB), a direct thrombin inhibitor, reportedly decreased the risk of major bleeding (MB) in AF ablation, compared to uninterrupted warfarin (NEJM 2017; 376:1627). Among DOACs, only regular-dose of DAB (150 mg b.i.d.), showed superiority to warfarin for preventing ischemic thromboembolism (TE) in patients with non-valvular AF, implicating the powerful anti-thrombotic agent. DAB may decrease the potential risk of procedure-related TE.
Purpose
To evaluate whether use of DAB on the day of AF ablation decreases the prevalence of silent cerebral ischemia (SCI) detected by magnetic resonance imaging (MRI).
Methods
414 AF patients on DOACs were enrolled and admitted on the day before AF ablation. Among 354 patients on factor Xa inhibitors (rivaroxaban, apixaban, and edoxaban), the original DOACs were switched to DAB (150 mg b.i.d.) on the day of the procedure in 172 patients (Group D); the treatment remained unchanged in 182 patients (Group non-D). In both groups, DOACs were continuously used throughout the procedure. After propensity-score matching, procedure-related parameters/events and the incidence of MRI-detected SCI were compared between Group D (n=134) and Group non-D (n=134). These parameters in patients originally taking DAB, used without interruption during the procedure (uninterrupted DAB, n=55), were also compared to Group D (n=55) after propensity-score matching.
Results
Baseline activated clotting time (ACT) before initial heparin injection was increased in Group D vs. Group-non-D (179±25* vs. 146±23 sec, *p<0.05 vs. Group non-D). The time to achieve optimal ACT (>300 sec) was shorter in Group D (34±29* vs. 43±32 min). The amounts of heparin needed to achieve optimal ACT and the total amount of heparin used during the procedure were unchanged between Group D and Group non-D. The incidence of SCI decreased in Group D (13.1%* vs. 21.9%), suggesting the potential anti-thrombotic efficacy of DAB. No MB or symptomatic TE events were observed in either group. Baseline ACT, the time to achieve ACT >300 sec, and the incidence of SCI in Group D were comparable to those in uninterrupted DAB (183±38 vs. 181±32 sec, 39±31 vs. 42±28 min, and 14.5% vs. 16.4%, respectively). No MB or symptomatic TE events were observed either in Group D or uninterrupted DAB.
Conclusions
Temporarily switching to DAB from the other DOACs and using it on the day of procedure enable us to achieve optimal ACT quickly and decrease the incidence of SCI, showing similar potential anti-thrombotic efficacy to uninterrupted DAB. Use of DAB on the day of AF ablation also benefits from the availability of its antidote in the case of MB during the procedure.

Abstract
We set out to examine the relations between prenatal exposure to the natural disaster Superstorm Sandy, maternal depression, and offspring electrodermal activity (EDA). EDA was measured via skin conductance response (SCR) magnitude in 198 children (M = 42.54 months, SD = 12.76) during a startle paradigm. In keeping with prior research, we expected prenatal depression to be associated with hyporeactive EDA and prenatal stress to be associated with hyperreactive EDA. SCR magnitude was lower in children prenatally exposed to depression alone, when compared to Superstorm Sandy, and controls. SCR magnitude of children prenatally exposed to both maternal depression and the storm was lower than that of all other groups. Our results emphasize the influence of maternal prenatal mental health, support targeted risk assessment for children who experienced an adverse prenatal environment, and highlight the need for a deeper understanding of the interactions between maternal mood and stress on the developing child.

Abstract
Objective To investigate the efficacy of minodronate in the treatment of glucocorticoid-induced osteoporosis (GIO). Methods The study population included patients in whom the administration of minodronate (50 mg, once every 4 weeks) had been newly started for the treatment of GIO in Niigata Rheumatic Center from 2012 to 2015. Patients who were bisphosphonate-naïve and those who switched from other bisphosphonates were classified into the naïve and switch groups, respectively. The changes in the bone mineral density (BMD) and bone metabolic markers after one year of minodronate treatment were retrospectively evaluated. We also compared the BMD and bone turnover marker changes of minodronate-naïve patients with those in whom alendronate or risedronate had been prescribed as a first bisphosphonate (control group). Results Minodronate was prescribed to 142 patients, and data were successfully obtained from 120 patients. New vertebral fractures were observed in 5 of the 142 patients; 1 fracture occurred during the cessation of minodronate for dental treatment, and 3 patients already had multiple vertebral fractures before the initiation of minodronate. The patients' tartrate-resistant acid phosphatase 5b (TRACP-5b) (-27.0%, p<0.001) and bone alkaline phosphatase (BAP) (-15.7%, p<0.01) levels were decreased, but no patients showed a decrease to below the normal range. One year of treatment with minodronate significantly increased the lumbar BMD in the naïve (+3.9%, p<0.001) and switch (+2.3%, p<0.001) groups. Although the femoral BMD did not change to a significant extent overall, the patients with a low young adult mean (YAM) (<80%) at baseline showed a significant increase in their femoral BMD (+2.1%, p=0.034) values. Compared with the control group, the minodronate-naïve group showed a significant decrease in the TRACP-5b levels and a significant increase in the lumbar BMD. Conclusion The administration of minodronate appears to be an effective treatment for GIO.

Abstract
A conjugate addition of diverse nucleophiles to acylketene acetals derived from 1,8-dihydroxynaphthalene (DHN) is developed for the formation of its 3-oxoalkan-1-one acetals. The initial acylketene acetals are prepared via double oxa-Michael addition of DHN to 1-bromo-1-propyn-3-ones. Carbonucleophiles, including organocopper reagents and active methylene compounds, and heteroatom nucleophiles were introduced under basic conditions. This method is applied for synthesizing spiropreussione A; the proposed structure does not correspond to that of the authentic natural product.

Abstract
OBJECTIVES The intensification of infliximab (IFX) treatment, involving escalation of the dose and shortening of interval, was approved in Japan in July 2009. We consider IFX intensification therapy to be preferable for patients with treatment-resistant active rheumatoid arthritis (RA). We retrospectively compared the efficacy of IFX with that of other bDMARDs in methotrexate (MTX)-resistant patients. METHODS Patients who satisfied the following criteria were enrolled: (i) those who started bDMARDs between February 2011 and December 2016, and (ii) those who required bDMARDs after 180 d of MTX treatment. We compared 33 patients who had been treated with IFX (IFX group) and 146 who had received other bDMARDs treatment (non-IFX group). RESULTS IFX was administered at a dose of 6.98 mg/kg/8-week equivalent at 52 weeks. Clinical disease activity index clinical remission (CDAI-CR) was achieved in 49 of the 179 patients at 52 weeks and 13 of these 49 patients received IFX. Logistic regression analysis showed that treatment with IFX was an important variable for the achievement of CDAI-CR at 52 weeks (odds ratio 2.69, 95% confidence interval 1.13-6.42). The severity and frequency of adverse events did not differ. CONCLUSION Intensification of IFX was effective and well tolerated for MTX resistant patients.

We measured, by angle-resolved photoemission spectroscopy, the electronic structure of LiCu_{2}O_{2}, a mixed-valence cuprate where planes of Cu(I) (3d^{10}) ions are sandwiched between layers containing one-dimensional edge-sharing Cu(II) (3d^{9}) chains. We find that the Cu(I)- and Cu(II)-derived electronic states form separate electronic subsystems, in spite of being coupled by bridging O ions. The valence band, of the Cu(I) character, disperses within the charge-transfer gap of the strongly correlated Cu(II) states, displaying an unprecedented 250% broadening of the bandwidth with respect to the predictions of density functional theory. Our observation is at odds with the widely accepted tenet of many-body theory that correlation effects generally yield narrower bands and larger electron masses and suggests that present-day electronic structure techniques provide an intrinsically inappropriate description of ligand-to-d hybridizations in late transition metal oxides.

Abstract
BACKGROUND Three-dimensional (3D) imaging has facilitated liver resection with excision of hepatic veins by estimating the liver volume of portal and hepatic venous territories. However, 3D imaging cannot be used for real-time navigation to determine the liver transection line. This study assessed the value of indocyanine green (ICG) fluorescence imaging with hepatic vein clamping for navigation during liver transection. METHODS Consecutive patients who underwent liver resection with excision of major hepatic veins between 2012 and 2013 were evaluated using ICG fluorescence imaging after clamping veins and injecting ICG. Regional fluorescence intensity (FI) values of non-veno-occlusive regions (FINon ), veno-occlusive regions (FIVO ) and ischaemic regions (FIIS ) were calculated using luminance analysing software. RESULTS Of the 21 patients, ten, four and seven underwent limited resection, monosegmentectomy/sectionectomy and hemihepatectomy respectively, with excision of major hepatic veins. Median veno-occlusive liver volume was 80 (range 30-458) ml. Fluorescence imaging visualized veno-occlusive regions as territories with lower FI compared with non-veno-occlusive regions, and ischaemic regions as territories with no fluorescence after intravenous ICG injection. Median FIIS /FINon was lower than median FIVO /FINon (0·22 versus 0·59; P = 0·002). There were no deaths in hospital or within 30 days, and only one major complication. CONCLUSION ICG fluorescence imaging with hepatic vein clamping visualized non-veno-occlusive, veno-occlusive and ischaemic regions. This technique may guide liver transection by intraoperative navigation, enhancing the safety and accuracy of liver resection.

Abstract
BACKGROUND The diagnosis of the progression of periodontitis presently depends on the use of clinical symptoms (such as attachment loss) and radiographic imaging. The aim of the multicenter study described here was to evaluate the diagnostic use of the bacterial content of subgingival plaque recovered from the deepest pockets in assessing disease progression in chronic periodontitis patients. METHODS This study consisted of a 24-month investigation of a total of 163 patients with chronic periodontitis who received trimonthly follow-up care. Subgingival plaque from the deepest pockets was recovered and assessed for bacterial content of Porphyromonas gingivalis, Prevotella intermedia, and Aggregatibacter actinomycetemcomitans using the modified Invader PLUS assay. The corresponding serum IgG titers were measured using ELISA. Changes in clinical parameters were evaluated over the course of 24 months. The sensitivity, specificity, and prediction values were calculated and used to determine cutoff points for prediction of the progression of chronic periodontitis. RESULTS Of the 124 individuals who completed the 24-month monitoring phase, 62 exhibited progression of periodontitis, whereas 62 demonstrated stable disease. The P. gingivalis counts of subgingival plaque from the deepest pockets was significantly associated with the progression of periodontitis (p < 0.001, positive predictive value = 0.708). CONCLUSIONS The P. gingivalis counts of subgingival plaque from the deepest pockets may be associated with the progression of periodontitis.

Abstract
The goals of the Japanese chapter of the Transplant Recipients International Organization are to act as a mediator in the provision of mutual aid to transplant recipients, candidates, and their families and to provide education in both the public and professional arenas to promote organ transplantation in Japan. Since 1991, members of the Japanese chapter of the Transplant Recipients International Organization have acted as volunteer facilitators for more than 150 transplant candidates and recipients. The organization's activities have included fund-raising to cover the costs of transplantation, preparing an original donor card for distribution, and petitioning members of the Diet (the Japanese legislative body) 14 times, including speaking at public hearings twice and submitting a petition requesting early passage of the organ transplant bill. The Japanese Diet finally passed an organ transplant bill in June 1997. The activities of the Japanese chapter of the Transplant Recipients International Organization have contributed to the promotion of organ transplantation in Japan and to understanding and support for transplantation within the Japanese community as a whole.
