Abstract
Background Posterolateral rotatory instability is produced by disruption of the lateral collateral ligament complex (LCLC); it is commonly induced by trauma, with few cases reported due to lateral epicondylitis. We examined the amount of posterior transition of the radial head with or without LCLC injury, common extensor tendon (CET) injury, and Baker classification in lateral epicondylitis. Methods We retrospectively studied patients with lateral epicondylitis of the humerus who underwent surgery between April 2016 and July 2021. Fifteen elbows with coronal and sagittal images on preoperative magnetic resonance imaging (MRI) were included. We investigated the amount of posterior transition of the radial head in sagittal MRI images of the elbow, which were compared based on LCLC and CET lesion. Results The mean age of patients was 49 years. The lesions in four, nine, and two patients were classified as LCLC0, LCLC1, and LCLC2, respectively. The mean radio-humeral distance values among the LCLC lesions were 0.65, 2.46, and 2.22 mm in LCLC0, LCLC1, and LCLC2, respectively, with the RHD between LCLC0 and LCLC1 differing significantly. In five, six, and four patients, the lesions were classified as CET1, CET2, and CET3, respectively. The mean RHD values among the CET lesions were 1.33, 2.68, and 1.48 mm in CET1, CET2, and CET3, respectively. Conclusions Our results showed that posterior transition of the radial head is greater in patients with lateral epicondylitis with LCLC lesions on MRI than those with normal findings of LCLC.

Abstract
BACKGROUND The purpose of scoring systems is to aid in the decision-making process of whether to salvage or amputate mangled extremities, but their efficacy for upper limbs is uncertain. In this study, we examined the predictive potential of scoring systems for upper limb salvage. METHODS Two investigators undertook a systematic search of 3 leading databases for English or Japanese literature from 1985, when the first scoring system to evaluate mangled extremities was proposed, until January 2022. To be eligible, studies must have had upper extremity limb salvage or amputation as an outcome, and identified the scoring system used and treatment outcome in individual cases. RESULTS Ten studies (N = 338) of the Mangled Extremity Scoring System (MESS) were ultimately included in the meta-analysis. The pooled sensitivity and specificity were 0.95 (95 % CI = 0.69-0.99) and 0.81 (0.65-0.91), respectively. The area under the hierarchical summary receiver operating characteristic curve was 0.95 (0.93-0.97). A subgroup analysis showed lower specificity in isolated vascular injuries. Scoring systems other than MESS were ineligible for the quantitative synthesis because none were examined in an adequate number of publications. CONCLUSION The pooled sensitivity and specificity for MESS were comparable to those reported for the lower extremities. The specificity suggests that limb salvage was achieved in at least 20 % of the patients whose MESS was above the threshold beyond which amputation is indicated. Given the likelihood of upper extremity functional limitations following amputation and the drawbacks of prostheses, we conclude that current scoring systems poorly predict salvageability of a mangled upper extremity and should not be used to justify amputation.

Abstract
Although various treatments for advanced stages of Kienböck's disease have been reported, clinical evidence demonstrating the efficacy of lunate resection and vascularized os pisiform transfer for Kienböck's disease is limited. Herein, we investigated the clinical and radiographic results of this procedure. We retrospectively investigated eight patients who were followed up for ≥1 year. The mean age at the time of surgery was 52 years. The mean follow-up period was 3.4 years. The preoperative and postoperative mean wrist flexion-extension ranges were 84° and 111°, respectively, and grip strengths were 18.5 and 26.3 kg, respectively. Pain decreased in five patients postoperatively. The mean preoperative and postoperative carpal height ratios were 0.47 and 0.46, respectively, and radio scaphoid angles were 63° and 65°, respectively. Osteoarthritic changes were observed in or around the transferred pisiform in all five patients who were surveyed using radiographs. Most patients demonstrated satisfactory clinical results, including pain relief and improved wrist motion and grip strength, regardless of osteoarthritic wrist changes on postoperative radiographs. In summary, this procedure was effective for treating Kienböck's disease, especially in the advanced stages. Level of evidence: Ⅳ.

Abstract
BACKGROUND Checkpoint inhibitors have shown improvement in recurrence-free survival in the post-operative setting for node-positive melanoma and were first approved in late 2015. However, single-agent checkpoint therapies have yet to show benefit to overall survival (OS) for lower-risk stage III cancers. We evaluated the OS benefit of post-operative immunotherapy in the National Cancer Database (NCDB). PATIENTS AND METHODS Patient cases were selected from the NCDB 2020 Participant Use File. Patients diagnosed with stage III cutaneous melanoma between 2016 and 2019 who underwent definitive resection for their melanoma were included. OS between those who received post-operative immunotherapy within 84 days of surgery and those who did not was analyzed by the Kaplan-Meier method. Demographic and clinical characteristics between the two groups were compared via Cox proportional hazard models. RESULTS 14 978 patients with stage III melanoma were included. Of those, 34.9% (n = 5234) received post-operative immunotherapy and 65.1% (n = 9744) did not. Using the American Joint Committee on Cancer version 8 (AJCCv8) staging, 36-month survival was significantly higher in patients who received post-operative immunotherapy compared to no post-operative systemic therapy in those diagnosed with stage IIIB (88.0% versus 84.7%, P = 0.011), IIIC (75.6% versus 68.1%, P < 0.001), or IIID (59.2% versus 48.4%, P = 0.002). No significant improvement in 36-month survival was seen in patients who received post-operative immunotherapy in patients with stage IIIA disease (93.0% versus 92.2%, P = 0.218). CONCLUSIONS Post-operative immunotherapy had an OS benefit in patients with AJCCv8 stage IIIB, IIIC, and IIID disease, but had no significant survival benefit for patients with stage IIIA melanomas.

Abstract
This study aimed to investigate the effects of the coronavirus disease 2019 (COVID-19) pandemic on patients with diabetes mellitus using patient-rated outcome measures focusing on hand function and quality of life, as well as patients' mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. It was a part of a longitudinal research involving patients with diabetes mellitus living in Sapporo, Japan. Among the 594 patients surveyed before the COVID-19 pandemic from March to June 2019, 417 patients who could be re-surveyed from March to June 2021 were included. We compared the patient-rated outcome measures, namely the Hand10 for hand function and EuroQol five-dimension questionnaire for assessing quality of life in the same population of patients with diabetes mellitus, before and during the COVID-19 pandemic. The results indicated no deterioration in the Hand10 (3.9 vs 3.6) and quality of life scores (0.89 vs 0.9), including mobility (1.25 vs 1.17), self-care (1.1 vs 1.08), pain/discomfort (1.43 vs 1.35), and anxiety/depression (1.21 vs 1.2), during the COVID-19 pandemic when compared with the pre-pandemic values. Usual activity values on the EuroQol five-dimension subscale significantly improved during the pandemic compared to those before the pandemic (1.21 vs 1.12, p<0.01). This study highlighted the effects of the COVID-19 pandemic on patients with diabetes mellitus by comparing patient-rated outcome measures in two different social situations. Patients with diabetes mellitus living in Sapporo, Japan maintained hand function and quality of life by continuing their usual activities during the COVID-19 pandemic.

Abstract
OBJECTIVES The purpose of this agreement was to establish evidence-based consensus statements on imaging of distal radioulnar joint (DRUJ) instability and triangular fibrocartilage complex (TFCC) injuries by an expert group using the Delphi technique. METHODS Nineteen hand surgeons developed a preliminary list of questions on DRUJ instability and TFCC injuries. Radiologists created statements based on the literature and the authors' clinical experience. Questions and statements were revised during three iterative Delphi rounds. Delphi panelists consisted of twenty-seven musculoskeletal radiologists. The panelists scored their degree of agreement to each statement on an 11-item numeric scale. Scores of "0," "5," and "10" reflected complete disagreement, indeterminate agreement, and complete agreement, respectively. Group consensus was defined as a score of "8" or higher for 80% or more of the panelists. RESULTS Three of fourteen statements achieved group consensus in the first Delphi round and ten statements achieved group consensus in the second Delphi round. The third and final Delphi round was limited to the one question that did not achieve group consensus in the previous rounds. CONCLUSIONS Delphi-based agreements suggest that CT with static axial slices in neutral rotation, pronation, and supination is the most useful and accurate imaging technique for the work-up of DRUJ instability. MRI is the most valuable technique in the diagnosis of TFCC lesions. The main indication for MR arthrography and CT arthrography are Palmer 1B foveal lesions of the TFCC. CLINICAL RELEVANCE STATEMENT MRI is the method of choice for assessing TFCC lesions, with higher accuracy for central than peripheral abnormalities. The main indication for MR arthrography is the evaluation of TFCC foveal insertion lesions and peripheral non-Palmer injuries. KEY POINTS • Conventional radiography should be the initial imaging technique in the assessment of DRUJ instability. CT with static axial slices in neutral rotation, pronation, and supination is the most accurate method for evaluating DRUJ instability. • MRI is the most useful technique in diagnosing soft-tissue injuries causing DRUJ instability, especially TFCC lesions. • The main indications for MR arthrography and CT arthrography are foveal lesions of the TFCC.

Abstract
Although anterior subcutaneous pelvic internal fixation is a valuable tool for the reduction and fixation of unstable pelvic ring injuries, lateral femoral cutaneous nerve irritation by the implant is the most common complication. This study aimed to investigate the association between the nerve-to-implant distance and the postoperative lateral femoral cutaneous nerve symptom. Patients who underwent anterior subcutaneous pelvic internal fixation between 2016 and 2019 were retrospectively analyzed. Lateral femoral cutaneous nerve status was defined as follows: not identified, nerve-to-implant distance <13 mm, and ≥13 mm. The proportion of patients who experienced postoperative nerve disorders was compared using the nerve status. Nerve-to-implant distances were compared using the presence or absence of postoperative lateral femoral cutaneous nerve disorders. The predictive value of a nerve-to-implant distance of 13 mm for postoperative nerve disorders was assessed. Overall, 26 lateral femoral cutaneous nerves were included. Ten patients had postoperative nerve disorders, of which seven had an nerve-to-implant distance <13 mm, while the other three occurred in patients whose nerves were not identified. A nerve-to-implant distance ≥13 mm was significantly associated with a decreased risk of postoperative nerve disorder compared to a nerve-to-implant distance <13 mm (p = 0.017). A nerve-to-implant distance ≥13 mm had a perfect sensitivity (100%) and modest specificity (58.3%). Nerve-to-implant distance was ≥13 mm. Nerve disorders were frequently observed when the nerve-to-implant distance was <13 mm or the nerve was not identified intraoperatively. Efforts to identify the lateral femoral cutaneous nerve may be useful to avoid internal fixation-related nerve disorders.

Abstract
BACKGROUND Ulnar shortening osteotomy (USO), as its name implies, is used to shorten the ulna. It subsequently tightens the triangular fibrocartilage complex (TFCC) and ulnar wrist. TFCC foveal insertion is a primary stabilizer of the distal radioulnar joint. It is unclear whether USO is effective in TFCC foveal injuries. The purpose of this study was to review the clinical outcomes of ulnar shortening osteotomies with and without TFCC foveal injuries. METHODS We retrospectively reviewed patients with ulnar wrist pain treated with USO and wrist arthroscopy including the distal radioulnar joint (DRUJ). Sixty-five patients were included in this study. An algorithm was used to guide surgical decision-making. After arthroscopic confirmation of ulnar impaction syndrome, we performed USO with a locking compression plate (mean length of shortening, 2.7 mm; range, 1-7.5 mm). The flattened TFCC disc due to ulnar shortening was confirmed arthroscopically. If the DRUJ was unstable after USO, we repaired the TFCC foveal insertion. RESULTS There were 32 post-traumatic and 33 idiopathic cases. We detected TFCC disc injuries in 34 wrists and TFCC foveal injuries in 33 wrists; both types were found in 15 wrists. TFCC foveal injuries were not significantly correlated with patient age, history of trauma, or clinical outcome. Most patients showed good clinical outcomes; 31 of 65 patients had preoperative DRUJ instability, with a significant number having foveal but not disc injuries. CONCLUSION USO achieved reasonable outcomes, even in patients with TFCC foveal injuries. In cases demonstrating ulnar impaction, USO should be prioritized over TFCC repair.

Abstract
Trigger finger is a common hand disorder; however, its pathogenesis remains unknown. In this study, we aimed to investigate mast cells, fibroblast activators that synthesize collagen, in the tendon sheaths of trigger fingers. We investigated the presence of mast cells and their association with changes in the collagen content of the tendon sheath and clinical data. We performed a multicenter prospective study of 77 adult patients with trigger finger who had undergone resection of the first annular pulley between August 2012 and January 2020. The tendon sheath was immunostained with an anti-tryptase antibody to confirm mast cell presence. The percentage of collagen in the tendon sheath was determined by picrosirius red staining observed through a polarization microscope. The clinical data, including the duration from symptom onset to surgery, severity, pain numerical rating scale, and Hand20 scores, were evaluated. Tryptase-positive mast cells were recognized in 83.5% of all specimens. The mast cell presence group (Group P) had a significantly higher percentage of type-3 collagen in the tendon sheath than the non-mast cell presence group (Group N) (Group P, 15.6%; Group N, 12.7%; p = 0.03). Moreover, Group P had significantly higher pain numerical rating scale (Group P; 5, Group N; 3, p = 0.04) and Hand20 (Group P; 35.5, Group N; 13.0, p = 0.01) scores than Group N. These findings suggest that mast cell presence in the tendon sheath of the trigger finger is related to the pathology and clinical symptoms of trigger finger.

Abstract
Hereditary neuropathy with liability to pressure palsy (HNPP) is a rare autosomal dominant disease characterized by focal, recurrent, demyelinating peripheral neuropathies. It is caused by deletions of the gene encoding for peripheral myelin protein 22 (PMP22) on chromosome 17. While it may range widely, the most common clinical presentation is an acute, focal mononeuropathy with numbness or muscle weakness after trauma or compression. Diagnostic tools include electrophysiological studies, genetic tests and nerve biopsies. There is no standard surgical or pharmacological treatment. The course of the disease is usually benign, with spontaneous improvement after most episodes of peripheral nerve palsy. HNPP is best managed by early detection, preventative measures, and subsequent treatment of symptoms. According to the medical literature, operative treatment was undertaken in few cases and limited to decompression of the nerve at the classic entrapment sites of the carpal or cubital tunnels. We present a case of multiple tendon transfer (pronator teres to extensor carpi radialis brevis and flexor carpi radialis to extensor digitorum communis) with a two-year follow-up in a 24-year-old woman with HNPP who was affected by irreversible radial nerve palsy, and conclude with a review of the medical literature related to the disease.

Abstract
Background Numerous studies have investigated surgical techniques for vascularised bone graft (VBG) for scaphoid nonunion; however, their efficacies remain unclear. Thus, to estimate the union rate of VBG for scaphoid nonunion, we performed a meta-analysis of randomised controlled trials (RCTs) and comparative studies. Methods A systematic search was conducted using PubMed, Scopus, Web of Science, and Cochrane Central Register of Controlled Trials. The search formula was as follows: ((scaphoid nonunion) OR (scaphoid pseudarthrosis)) AND (bone graft). Only RCTs were used in the primary analysis, and comparative studies, including RCTs, in the secondary analysis. The primary outcome was nonunion rate. We compared the outcome between VBG and non-vascularised bone graft (NVBG), pedicled VBG and NVBG, and free VBG and NVBG. Results This study included a total of 4 RCTs (263 patients) and 12 observational studies (1411 patients). In the meta-analyses of both RCTs only and RCTs and other comparative studies, no significant difference in nonunion rate was found between VBG and NVBG (summary odds ratio [OR], 0.54; 95% confidence interval [CI], 0.19-1.52 and summary OR, 0.71; 95% CI, 0.45-1.12), respectively. The nonunion rates of pedicled VBG, free VBG, and NVBG were 15.0%, 10.2%, and 17.8%, respectively, and no significant difference was found. Conclusions Our results indicated that the postoperative union rate in NVBG is similar to that in VBG; thus, NVBG could be the first choice of treatment for scaphoid nonunion.

Abstract
This systematic review aimed to confirm the effectiveness of hand therapy programmes using the International Classification of Functioning, Disability and Health framework for each of the three phases of the wound healing process in adults with burns. A systematic review was conducted to determine the efficacy of different hand therapy programmes in the management of burnt hands. Two independent reviewers conducted a literature search using the PubMed and Cumulative Index to Nursing and Allied Health Literature databases for original articles reporting effectiveness of hand therapy programmes for adults with burns. Only randomized and non-randomized controlled trials were selected using the Mixed Methods Appraisal Tool. Demographic and clinical data including medical history, burn depth, and hand therapy programme were extracted. Outcome measures were reviewed based on the International Classification of Functioning, Disability and Health framework for acute, convalescence, and chronic phases of rehabilitation. Sixteen articles and 15 hand therapy programmes were identified, which included studies showing improvements in different parameters in the framework. In the acute and convalescence phases, improvements were found in health condition, body functions and structures, activities, and participation. In the chronic phase, improvements were shown only in body functions and structures. Environmental factors in the framework were not reported for all the phases. This review demonstrated the efficacy of hand therapy programmes in adults with burns in terms of the health condition, body function, activities, and participation during acute and convalescence phases but only the body function in the chronic phase.

Abstract
On-top plasty may be the best option for reconstructing atypical radial polydactyly, consisting of a developed distal portion in one thumb and a developed proximal portion in the other thumb. However, it is unclear if patients can gain thumb function corresponding to the reconstructed appearance. We performed a retrospective bibliographic review to summarize the current literature and present our department's on-top plasty experiences. Over the last ten years, our department performed three on-top plasty radial polydactyly reconstructions. We surveyed the appearance and use of the reconstructed thumb and the patient's satisfaction level during postoperative follow-up. We also retrieved published case reports describing on-top plasty for polydactyly reconstruction to compare with our cases. Our patients had an acceptable thumb appearance and were satisfied with the gained function of the thumb. However, two patients required revision surgery. We found 11 studies in the literature describing on-top plasty for polydactyly treatment, four of which reported a limited range of thumb motion, but no patient or their family complained about the result. Most patients who undergo on-top plasty for radial polydactyly can expect a fair to good appearance after surgery. Although instability or limitation of the joint arc is possible, the reconstruction satisfies patients regarding function and appearance.

Abstract
Abstract
Background
Although risk stratification is important in patients with acute heart failure (AHF) to predict patient prognosis, pre-existing risk models have not often been used due to its complexity. Recently, machine learning methods have been presented as an alternative approach to analyzing the predictive probability of large clinical datasets.
Purpose
The aim of this study is to develop a user-friendly risk score developed by one of machine learning methods and compare the performance of the new risk score to the existing conventional risk models.
Methods
A machine-learning-based risk model was developed using least absolute shrinkage and selection operator (LASSO) regression by identifying predictors of in-hospital mortality in the derivation cohort (REALITY-AHF) and externally validating and comparing its performance with two pre-existing risk models: the Get With The Guidelines risk score incorporating brain natriuretic peptide and hypochloremia (GWTG-BNP-Cl-RS) and the acute decompensated heart failure national registry (ADHERE) risk model.
Results
In-hospital deaths in the derivation and validation (NARA-HF) cohorts were 76 (5.1%) and 61 (4.9%), respectively. The risk score comprised four variables (systolic blood pressure, blood urea nitrogen, serum chloride, and C-reactive protein) and was developed according to the results of the LASSO regression weighting the coefficient for selected variables using a logistic regression model (4V-RS). Even though 4V-RS comprised fewer variables, In the validation cohort, it showed a higher area under the receiver operating characteristic curve (AUC) than the ADHERE risk model (AUC, 0.783 vs. 0.740; P=0.059) and a significant improvement in net reclassification (0.359; 95% CI, 0.10–0.67; p=0.006). 4V-RS performed similarly to GWTG-BNP-Cl-RS in terms of discrimination (AUC, 0.783 vs. 0.759; p=0.426) and net reclassification (0.176; 95% CI, −0.08–0.43; p=0.178).
Conclusions
The 4V-RS model comprising only four readily available data points at the time of admission performed similarly to the more complex pre-existing risk model in patients with AHF.

Abstract
We analyzed trends in open and endoscopic carpal tunnel release (CTR) from 2014 to 2019 using the National Database of Health Insurance Claims and Specific Health Checkups in Japan (NDB). Japan has a universal health insurance system and more than 95% of all claims are searchable in the NDB open data repository. The results revealed that nearly 40,000 CTRs were performed annually in Japan, and open CTR was performed almost 4 times more often than endoscopic CTR. The crude annual incidence of CTR in the general population among people 20 years of age or older was 32.2 per 100,000. The incidence of open CTR peaked in the 80–84 age range for both males and females. The incidence of endoscopic CTR peaked at 80–84 years in females and at 75–79 years in males. There was a mild correlation coefficient between the endoscopic CTRs and the number of hand surgery specialists by prefecture per population (r = 0.32, p = 0.04). However, the number of hand surgeons per capita by region and open CTR per capita was not correlated (r = 0.06, p = 0.67). There were about twice as many outpatient as inpatient surgeries, reflecting a trend toward ambulatory treatment.

Abstract
Study question
Despite the high rate of sperm chromosome abnormalities in testicular germ cell tumor (TGCT), why is newborn aneuploidy rate in pregnancies with TGCT patient normal?
Summary answer
Miscarriage rate is higher in the pregnancy of TGCT patients than of non-TGCT cancer patients, although the pregnancy rate in ICSI was not significantly different.
What is known already
Previous reports showed higher sperm aneuploidy in TGCT patients than control males. The sperm aneuploidy rate is high before treatment, and after radical treatments peaked at 6 months after treatment and remained high until 24 months after treatment. However, in the Swedish government base study, the rate of newborn malformations including aneuploidy in all pregnancy with TGCT patients was higher than without TGCT, but not statistically significant. In only natural pregnancies, the rate was not significantly different between the two groups. The cause for discrepancy within sperm aneuploidy and newborn aneuploidy was not well clarified.
Study design, size, duration
To clarify the mechanism for the purifying selection of aneuploid sperm in conception, we examined ICSI cases with TGCT patients that did not include natural sperm competition and compared to controls with non-TGCT cancer patient, who have normal rate of aneuploid sperm. By investigating ICSI outcomes, we aimed to determine which stage of embryonic development are affected by the sperm of TGCT patients.
Participants/materials, setting, methods
Under ethical review of Yokohama city university, the 10 TGCT patients (123 oocytes) and 16 non-TGCT cancer patients (251 oocytes) who underwent ICSI with their frozen sperm from 2012 to 2021 were enrolled. Fertilization, embryo viability and embryo transfer outcomes (pregnancy and miscarriage rate) were examined between two groups underwent ICSI with cryopreserved sperm for fertility preservation. Clinical information was retrospectively collected from medical records.
Main results and the role of chance
The patients' age of sperm cryopreservation was 21-56 years old. 10 cases of TGCT were diagnosed as seminoma (3), non seminoma (6), and unknown (2). 15 cases of non-TGCT were diagnosed as malignant blood diseases (9), prostate cancer (2), bladder cancer (1), and others (3). In both groups, all patients were treated by ICSI with cryopreserved sperm obtained prior to chemotherapy. The mean age of female partners in TGCT was 33.2±3.5 years and not different with 35.8±3.4 years in non-TGCT meaning no different age factor. The fertilization rate, viable embryo rate, pregnancy rate and chemical abortion rate of TGCT vs non-TGCT group were 76.4% vs 67.7%, 64.3% vs 61.7%, 37.1% vs 21.7%, 7.1% vs 23.1%, respectively. Those developmental evaluations were not significantly different between two groups. However, spontaneous abortion rate was significantly higher 46.2% in TGCT group than 10% in non-TGCT group (p < 0.05). Further, in our follow-up, no congenital malformations in the babies born in either group (5 babies in TGCT vs 7 babies in non-TGCT group). The outcome of ICSI using sperm in TGCT patients show normal pregnancy rate but include higher spontaneous abortions rate, suggesting aneuploid embryo were negatively purifying selected under post-implantation stage.
Limitations, reasons for caution
Because ICSI with fertility-preserving frozen sperm in TGCT patient is rare even in reproduction center in general university hospital, single center analysis is still small and limited. More case reports and studies for TGCT fertility preservation are needed for more accurate evaluation.
Wider implications of the findings
In TGCT patients, chromosome aberrations and DNA fragmentation of sperm may not be apparent in natural pregnancies with normal sperm competition, but may become apparent as spontaneous abortions when ICSI were performed, suggesting PGT-A can predict and avoid the hidden risk of repeated pregnancy loss in ICSI to TGCT patients.

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
This study compared hand function and the cost-effectiveness of treatment between collagenase Clostridium histolyticum (CCH) injection and limited fasciectomy for patients with Dupuytren’s contracture (DC). The CeCORD-J study is a prospective, multicenter, non-randomized controlled, observational study of two parallel groups. Participants were DC patients with multiple affected fingers, including flexion contracture of the proximal interphalangeal (PIP) joint. The primary outcome was the Hand10 score, as a patient-reported outcome measure (PROM). We set secondary outcomes of EQ-5D-5L (QOL) score, degree of extension deficit, and direct cost. Propensity score adjustment was used to balance differences in patient characteristics between groups. Participants comprised 52 patients in the Collagenase group and 26 patients in the Surgery group. There were no significant differences in the Hand10 and QOL scores between the two groups at 26 weeks. Mean direct cost was 248,000 yen higher in the Surgery group than in the Collagenase group. Extension deficit angle of the PIP joint was significantly larger in the Collagenase group at 26 weeks. Although the Collagenase group showed dominance in cost-effectiveness, there was no significant difference between the two groups in hand function at 26 weeks.

Abstract
Although good clinical results have been reported following lunate resection and vascularized os pisiform transfer for advanced stages of Kienböck's disease, the occurrence of wrist osteoarthritis has been highlighted. We aimed to investigate the postoperative condition of the pisiform and the surrounding bones in patients who underwent surgery for advanced stages of Kienböck's disease using magnetic resonance imaging. We retrospectively reviewed the data of six patients (mean age, 45 years; Lichtman stage, IIIb) who underwent lunate resection and vascularized os pisiform transfer for advanced stages of Kienböck's disease and postoperative magnetic resonance imaging examination. We extracted clinical data on pre- and postoperative range of motion, grip strength, wrist pain, Hand20 and Lichtman's criteria, and pre- and postoperative radiographic and magnetic resonance imaging examinations. Bone marrow lesions in the transferred pisiform were found in five patients. Signal changes of bones around the transferred pisiform were found in these five patients; the greatest change was observed in the capitate bone in three patients. These signal changes were found in the opposite parts of the bones around the transferred pisiform. No patient exhibited signal changes in the transferred pisiform bone only. Wrist osteoarthritis after lunate resection and vascularized os pisiform transfer for advanced stages of Kienböck's disease is more likely to be attributed to the low congruency of the transferred pisiform and surrounding bones than to the compromised perfusion of the pisiform. Signal changes in the opposite bone parts around the transferred pisiform were confirmed in all patients with signal changes in the pisiform.

Abstract
OBJECTIVES To evaluate the characteristics of sarcopenic dysphagia (SD) and the prognosis of swallowing function in convalescent rehabilitation hospital patients; and to investigate the association between malnutrition severity and SD. DESIGN A prospective, multi-center, cohort study. SETTING We extracted registry data from the Japanese Sarcopenic Dysphagia Database, focusing on patients admitted to convalescent rehabilitation hospitals. PARTICIPANTS A total of 207 participants were recruited and stratified according to the presence or absence of SD. Next, the participants were divided into groups based on nutrition status using the Global Leadership Initiative on Malnutrition criteria: normal nutrition, moderate malnutrition, and severe malnutrition. We also compared the outcomes between patients with SD (SD group) and those without SD (no-SD group) according to malnutrition status. MEASUREMENTS The Food Intake LEVEL Scale (FILS) score was the outcome measure. Higher scores on the FILS indicate better swallowing function. We compared the patient characteristics between the SD and non-SD groups among all patients and then according to the severity of malnutrition. RESULTS A total of 207 patients were recruited. 11 were diagnosed with normal nutrition, 72 with moderate malnutrition, and 124 with severe malnutrition. There were 128 participants with SD and 79 participants without SD; the prevalence of SD was 61.8%. Hip fracture was the most common disease among the SD patients (34.4%). The median time to the end of follow-up was 73.5 days for the SD group and 84.0 days for the no-SD group. There was no significant difference in the FILS score between the SD and no-SD groups, but the increase in the FILS score was significantly lower in the SD group than the no-SD group among patients with severe malnutrition after adjusting for confounding factors (age, sex, FILS at admission, BMI, cognitive functional independence measure, and care level before onset) (β = -0.206, p = 0.011, 95% confidence interval = -0.723, -0.098). CONCLUSION Orthopedic diseases are the most common type of disease among SD patients in convalescent rehabilitation hospitals. Swallowing dysfunction was particularly severe in malnourished patients with SD. This result suggests the importance of the definition of SD for malnourished patients. We should practice nutritional management as soon as possible in severely malnourished patients diagnosed with SD.

Abstract
Abstract
Introduction
Right ventricular free wall longitudinal strain (RVFWLS) is a sensitive tool for right ventricular (RV) function assessment. Furthermore, it shows incremental prognostic role in various cardiac diseases. RV involvement is frequently observed along with left ventricular (LV) involvement in cardiac sarcoidosis (CS) patients, while its impact on outcome is unclear.
Purpose
The aim of this study is to investigate the association between RV dysfunction detected by RVFWLS and cardiovascular event in patients with CS.
Methods
We retrospectively evaluated 51 patients with CS who were treated with prednisone from 2012 through 2020. Diagnosis of CS was made according to the Japanese Circulation Society diagnostic criteria. We evaluated RVFWLS at baseline using vender-independent software. We considered major adverse cardiovascular event (MACE: ventricular arrhythmia, heart failure hospitalization) to be the primary outcome.
Results
Mean age of the study population was 63±11 years, and 61% were female. At baseline, 25 patients (49%) had reduced left ventricular (LV) ejection fraction (EF) (<50%) and 18 patients (35%) had impaired RVFWLS (<17%). Patients with impaired RVFWLS showed lower LVEF% (42±12% vs. 53±13%, P=0.005) and larger LV end-systolic volume index (54±33 vs. 37±23ml/m2, P=0.04) compared with those with preserved RVFWLS. Impaired RVFWLS patients also showed trend towards higher prevalence of basal interventricular thinning (50 vs. 28%, P=0.12). During a median follow-up of 548 days, eleven patients had MACE. In multivariable Cox-proportional hazards model analysis, RVFWLS was independently associated with MACE (HR 1.28, 95% CI: 1.07–1.10, P=0.009). Kaplan-Meier survival curves showed worse event-free survival in patients with impaired RVFWLS (log-rank test, P=0.001).
Conclusions
In patients with CS, RVFWLS is an independent predictor for MACE. RVFWLS may be valuable in improving risk stratification in CS.

Abstract
OBJECTIVE A trial comparing prenatal with postnatal open spina bifida (OSB) repair established that prenatal surgery was associated with better postnatal outcome. However, in the trial, fetal surgery was carried out through hysterotomy. Minimally invasive approaches are being developed to mitigate the risks of open maternal-fetal surgery. The objective of this study was to investigate the impact of a novel neurosurgical technique for percutaneous fetoscopic repair of fetal OSB, the skin-over-biocellulose for antenatal fetoscopic repair (SAFER) technique, on long-term postnatal outcome. METHODS This study examined descriptive data for all patients undergoing fetoscopic OSB repair who had available 12- and 30-month follow-up data for assessment of need for cerebrospinal fluid (CSF) diversion and need for bladder catheterization and ambulation, respectively, from eight centers that perform prenatal OSB repair via percutaneous fetoscopy using a biocellulose patch between the neural placode and skin/myofascial flap, without suture of the dura mater (SAFER technique). Univariate and multivariate logistic regression analyses were used to examine the effect of different factors on need for CSF diversion at 12 months and ambulation and need for bladder catheterization at 30 months. Potential cofactors included gestational age at fetal surgery and delivery, preoperative ultrasound findings of anatomical level of the lesion, cerebral lateral ventricular diameter, lesion type and presence of bilateral talipes, as well as postnatal findings of CSF leakage at birth, motor level, presence of bilateral talipes and reversal of hindbrain herniation. RESULTS A total of 170 consecutive patients with fetal OSB were treated prenatally using the SAFER technique. Among these, 103 babies had follow-up at 12 months of age and 59 had follow-up at 30 months of age. At 12 months of age, 53.4% (55/103) of babies did not require ventriculoperitoneal shunt or third ventriculostomy. At 30 months of age, 54.2% (32/59) of children were ambulating independently and 61.0% (36/59) did not require chronic intermittent catheterization of the bladder. Multivariate logistic regression analysis demonstrated that significant prediction of need for CSF diversion was provided by lateral ventricular size and type of lesion (myeloschisis). Significant predictors of ambulatory status were prenatal bilateral talipes and anatomical and functional motor levels of the lesion. There were no significant predictors of need for bladder catheterization. CONCLUSION Children who underwent prenatal OSB repair via the percutaneous fetoscopic SAFER technique achieved long-term neurological outcomes similar to those reported in the literature after hysterotomy-assisted OSB repair. © 2021 The Authors.

Abstract
Background: The usefulness of radial osteotomy for older patients remains unclear. The purpose of this study was to compare the clinical and radiological outcomes of radial osteotomy with volar locking plate between younger and older patients with Kienböck disease stages II to IIIB. Methods: This was a retrospective comparative study of 21 consecutive patients treated at our department. Lichtman's classification was used for staging, and four patients had stage II, six patients had stage IIIA, and 11 patients had stage IIIB disease. We divided them into two groups to compare the radiological and clinical results between younger (younger than 40 years) and older patients. The mean follow-up periods in the younger and older groups were 4 and 3.6 years, respectively. For radiological assessment, we evaluated the carpal height ratio (CHR), Stahl index, and union of the fractured lunate. For clinical assessment, we examined the range of motion of the wrist, grip strength, numeric rating scale (NRS) for pain, and the patient-reported Hand20 score preoperatively and at the final follow-up. Results: There were 12 patients in the younger group with a mean age of 23 years (range, 12-37 years), and 9 in the older group with a mean age of 56 years (range, 40-74 years). There were no intra- and post-operative complications in either group. Radiological improvement, including CHR, Stahl index, and union of the fractured lunate, was more common in the younger group than in the older one, as was the case for clinical improvement. However, even in the older group, significant clinical improvement, including the range of motion of the wrist, NRS for pain, and the Hand20 score, was seen postoperatively. Conclusions: Radial osteotomy appears to be a safe and reliable option in older symptomatic patients with Kienböck disease stages II to IIIB.

Abstract
14 normal subjects were given two tactile-recognition tasks. Subjects were asked to match the factually presented nonsense figures to the visual-recognition display on a Non-rotation task. On the Mental-rotation task subjects matched the tactile figures which were presented in various directions by means of mental rotation to the visual display. A greater superiority of the left hand on the Mental-rotation task was noted while on the Non-rotation task no differences between hands were shown. The right hemisphere may contribute more strongly to higher thought processes especially those which do not need verbal mediation.

Abstract
Objectives The purpose of this agreement was to establish evidence-based consensus statements on imaging of scapholunate joint (SLJ) instability by an expert group using the Delphi technique. Methods Nineteen hand surgeons developed a preliminary list of questions on SLJ instability. Radiologists created statements based on the literature and the authors’ clinical experience. Questions and statements were revised during three iterative Delphi rounds. Delphi panellists consisted of twenty-seven musculoskeletal radiologists. The panellists scored their degree of agreement to each statement on an eleven-item numeric scale. Scores of ‘0’, ‘5’ and ‘10’ reflected complete disagreement, indeterminate agreement and complete agreement, respectively. Group consensus was defined as a score of ‘8’ or higher for 80% or more of the panellists. Results Ten of fifteen statements achieved group consensus in the second Delphi round. The remaining five statements achieved group consensus in the third Delphi round. It was agreed that dorsopalmar and lateral radiographs should be acquired as routine imaging work-up in patients with suspected SLJ instability. Radiographic stress views and dynamic fluoroscopy allow accurate diagnosis of dynamic SLJ instability. MR arthrography and CT arthrography are accurate for detecting scapholunate interosseous ligament tears and articular cartilage defects. Ultrasonography and MRI can delineate most extrinsic carpal ligaments, although validated scientific evidence on accurate differentiation between partially or completely torn or incompetent ligaments is not available. Conclusions Delphi-based agreements suggest that standardized radiographs, radiographic stress views, dynamic fluoroscopy, MR arthrography and CT arthrography are the most useful and accurate imaging techniques for the work-up of SLJ instability. Key Points • Dorsopalmar and lateral wrist radiographs remain the basic imaging modality for routine imaging work-up in patients with suspected scapholunate joint instability. • Radiographic stress views and dynamic fluoroscopy of the wrist allow accurate diagnosis of dynamic scapholunate joint instability. • Wrist MR arthrography and CT arthrography are accurate for determination of scapholunate interosseous ligament tears and cartilage defects.

Abstract
Transplantation of embryonic motor neurons has been shown to improve motor neuron survival and innervation of neuromuscular junctions in peripheral nerves. However, there have been no reports regarding transplantation of sensory neurons and innervation of sensory receptors. Therefore, we hypothesized that the transplantation of embryonic sensory neurons may improve sensory neurons in the skin and innervate Merkel cells and Meissner's corpuscles. We obtained sensory neurons from dorsal root ganglia of 14-day rat embryos. We generated a rat model of Wallerian-degeneration by performing sciatic nerve transection and waiting for one week after. Six months after cell transplantation, we performed histological and electrophysiological examinations in naïve control, surgical control, and cell transplantation groups. The number of nerve fibers in the papillary dermis and epidermal-dermal interface was significantly greater in the cell transplantation than in the surgical control group. The percent of Merkel cells with nerve terminals, as well as the average number of Meissner corpuscles with nerve terminals, were higher in the cell transplantation than in the surgical control group, but differences were not significant between the two groups. Moreover, the amplitude and latency of sensory conduction velocity were evoked in rats of the cell transplantation group. We demonstrated that the transplantation of embryonic dorsal root ganglion cells improved sensory nerve fiber number and innervation of Merkel cells and Meissner's corpuscles in peripheral nerves.

Abstract
OBJECTIVES To assess how patient characteristics and study design influence the effectiveness of control interventions in hand OA trials. METHODS The study protocol was registered in PROSPERO (CRD42020163473). Two authors independently searched four electronic databases from their inception to December 31, 2019. Randomized and non-randomized controlled hand OA trials were included if pain intensity was assessed using a validated scale. We allocated control groups into one of the following: placebo, add-on treatment, no treatment, or active treatment. The standardized mean differences (d) of pain, as well as subjective function and hand strength, were pooled with 95% confidence intervals (CI) and 90% prediction intervals using random-effects models. Meta-regression and post-hoc subgroup analyses were performed to investigate which factors potentially impacted placebo analgesia and between-study heterogeneity. RESULTS Thirty-one placebo, 11 add-on, 12 no-treatment, and 10 active-treatment controls were included in meta-analyses. Effective pain relief was observed in placebo (d = -0.50, 95% CI -0.63 to -0.37), add-on (d = -0.35, 95% CI -0.59 to -0.12), and active-treatment (d = -0.92, 95% CI -1.35 to -0.48) groups. In subjective function, these treatments had smaller but beneficial effects; hand strength, contrastingly, was not improved. Placebo effects were larger when flare designs were used (d = -0.96) and more homogeneous when minimum pain thresholds were set (d = -0.46, 90% prediction intervals -0.79 to -0.14). CONCLUSION Placebo, add-on, and active control treatments were more effective than the no treatment control in relieving hand pain and improving subjective function. By choosing minimum pain thresholds and flare requirements at patient enrollment, moderate pain relief may be replicated among control participants in future randomized placebo-controlled trials.

Abstract
Objective: Trimethoprim-sulfamethoxazole (TMP/SMX) prophylaxis against Pneumocystis jirovecii pneumonia (PJP) is routinely administered to patients with rheumatic diseases in Japan. The present study aimed to evaluate the effect of TMP/SMX prophylaxis on PJP and non-central line-associated bloodstream infections (BSIs) in patients receiving high-dose glucocorticoids for the treatment of rheumatic diseases.Method: This study enrolled patients who were admitted between 1 October 2003 and 31 March 2018 and began high-dose glucocorticoid therapy for rheumatic diseases during hospitalization. The observation period was 4 months from the commencement of high-dose glucocorticoid therapy. The effect of TMP/SMX prophylaxis on PJP and non-central line-associated BSI was analysed.Results: Of the 437 patients included in the study, 376 received TMP/SMX prophylaxis and 61 patients did not. During the observation period, TMP/SMX prophylaxis was discontinued in 76 patients (20.2%). Three PJP cases (0.7%) occurred. Among the 399 patients included in our analysis of non-central line-associated BSI, eight experienced non-central line-associated BSI (2.0%). Among the covariates, TMP/SMX prophylaxis was associated with reduced PJP and non-central line-associated BSI incidence [odds ratio (OR) 0, 95% confidence interval (CI) 0.00-0.38, and OR 0.08, 95% CI 0.01-0.42, respectively].Conclusion: Routine TMP/SMX prophylaxis reduced the incidence of both PJP and BSI in patients with rheumatic diseases undergoing high-dose glucocorticoid therapy.

Abstract
BACKGROUND Laparoscopic liver resection for hepatocellular carcinoma (HCC) in Child-Pugh A cirrhosis has been demonstrated as beneficial. However, the role of laparoscopy in Child-Pugh B cirrhosis is undetermined. The aim of this retrospective cohort study was to compare open and laparoscopic resection for HCC with Child-Pugh B cirrhosis. METHODS Data on liver resections were gathered from 17 centres. A 1 : 1 propensity score matching was performed according to 17 predefined variables. RESULTS Of 382 available liver resections, 100 laparoscopic and 100 open resections were matched and analysed. The 90-day postoperative mortality rate was similar in open and laparoscopic groups (4.0 versus 2.0 per cent respectively; P = 0.687). Laparoscopy was associated with lower blood loss (median 110 ml versus 400 ml in the open group; P = 0.004), less morbidity (38.0 versus 51.0 per cent respectively; P = 0.041) and fewer major complications (7.0 versus 21.0 per cent; P = 0.010), and ascites was lower on postoperative days 1, 3 and 5. For laparoscopic resections, patients with portal hypertension developed more complications than those without (26 versus 12 per cent respectively; P = 0.002), and patients with a Child-Pugh B9 score had higher morbidity rates than those with B8 and B7 (7 of 8, 10 of 16 and 21 of 76 respectively; P < 0.001). Median hospital stay was 7.5 (range 2-243) days for laparoscopic liver resection and 18 (3-104) days for the open approach (P = 0.058). The 5-year overall survival rate was 47 per cent for open and 65 per cent for laparoscopic resection (P = 0.142). The 5-year disease-free survival rate was 32 and 37 per cent respectively (P = 0.742). CONCLUSION Patients without preoperative portal hypertension and Child-Pugh B7 cirrhosis may benefit most from laparoscopic liver surgery.

Abstract
The number of elderly patients with esophageal cancer has increased in recent years. The use of thoracoscopic esophagectomy has also increased, and its minimal invasiveness is believed to contribute to postoperative outcomes. However, the short- and long-term outcomes in elderly patients remain unclear. This study aimed to elucidate the safety and feasibility of minimally invasive esophagectomy in elderly patients. This retrospective study included 207 patients who underwent radical thoracoscopic esophagectomy for thoracic esophageal squamous cell carcinoma at Kobe University Hospital between 2005 and 2014. Patients were divided into non-elderly (<75 years) and elderly (≥75 years) groups. A propensity score matching analysis was performed for sex and clinical T and N stage, with a total of 29 matched pairs. General preoperative data, surgical procedures, intraoperative data, postoperative complications, in-hospital death, cancer-specific survival, and overall survival were compared between groups. The elderly group was characterized by lower preoperative serum albumin levels and higher American Society of Anesthesiologists grade. Intraoperative data and postoperative complications did not differ between the groups. The in-hospital death rate was 4% in the elderly group, which did not significantly differ from the non-elderly group. Cancer-specific survival was similar between the two groups. Although overall survival tended to be poor in the elderly group, it was not significantly worse than that of the non-elderly group. In conclusion, the short- and long-term outcomes of minimally invasive esophagectomy in elderly versus non-elderly patients were acceptable. Minimally invasive esophagectomy is a safe and feasible modality for elderly patients with appropriate indications.

Abstract
FtsJ RNA 2'-O-methyltransferase 1 (FTSJ1) gene has been implicated in X-linked intellectual disability (XLID), but the molecular pathogenesis is unknown. We show that Ftsj1 is responsible for 2'-O-methylation of 11 species of cytosolic transfer RNAs (tRNAs) at the anticodon region, and these modifications are abolished in Ftsj1 knockout (KO) mice and XLID patient-derived cells. Loss of 2'-O-methylation in Ftsj1 KO mouse selectively reduced the steady-state level of tRNAPhe in the brain, resulting in a slow decoding at Phe codons. Ribosome profiling showed that translation efficiency is significantly reduced in a subset of genes that need to be efficiently translated to support synaptic organization and functions. Ftsj1 KO mice display immature synaptic morphology and aberrant synaptic plasticity, which are associated with anxiety-like and memory deficits. The data illuminate a fundamental role of tRNA modification in the brain through regulation of translation efficiency and provide mechanistic insights into FTSJ1-related XLID.

Abstract
The purpose of this study was to develop and evaluate a novel elbow arthroscopy system with superimposed bone and nerve visualization using preoperative computed tomography (CT) and magnetic resonance imaging (MRI) data. We obtained bone and nerve segmentation data by CT and MRI, respectively, of the elbow of a healthy human volunteer and cadaveric Japanese monkey. A life size 3-dimensional (3D) model of human organs and frame was constructed using a stereo-lithographic 3D printer. Elbow arthroscopy was performed using the elbow of a cadaveric Japanese monkey. The augmented reality (AR) range of error during rotation of arthroscopy was examined at 20 mm scope-object distances. We successfully performed AR arthroscopy using the life-size 3D elbow model and the elbow of the cadaveric Japanese monkey by making anteromedial and posterior portals. The target registration error was 1.63 ± 0.49 mm (range 1-2.7 mm) with respect to the rotation angle of the lens cylinder from 40° to - 40°. We attained reasonable accuracy and demonstrated the operation of the designed system. Given the multiple applications of AR-enhanced arthroscopic visualization, it has the potential to be a next-generation technology for arthroscopy. This technique will contribute to the reduction of serious complications associated with elbow arthroscopy.

Abstract
We develop a coherent beam splitter for single electrons driven through two tunnel-coupled quantum wires by surface acoustic waves (SAWs). The output current through each wire oscillates with gate voltages to tune the tunnel coupling and potential difference between the wires. This oscillation is assigned to coherent electron tunneling motion that can be used to encode a flying qubit and is well reproduced by numerical calculations of time evolution of the SAW-driven single electrons. The oscillation visibility is currently limited to about 3%, but robust against decoherence, indicating that the SAW electron can serve as a novel platform for a solid-state flying qubit.

Background
Left atrial (LA) function is impaired in heart failure with preserved ejection fraction (HFpEF). However, the association between LA longitudinal strain and heart failure (HF) events in patients with HFpEF is still unknown. We evaluated whether LA strain measurements would be useful to predict hospitalizations for worsening HF in this study.
Methods
This study included 121 patients (Male 73, Female 48) with HFpEF who had echocardiogram at our institute (Age = 76 ± 14y, Left ventricular ejection fraction; LVEF = 63 ± 8%). Patients with atrial fibrillation were excluded. LA longitudinal strain was measured by speckle-tracking echocardiography, using TOMTEC imaging system. The endpoints were hospitalizations for worsening HF.
Results
During follow-up period of 319 ± 269 days, 33 patients (27%) experienced hospitalizations for worsening HF. LA strain was markedly lower in patients with HF events at 11.3 ± 5.6, whereas LA strain was higher at 20.3 ± 10.1 in patients without HF events. Kaplan-Meier analysis demonstrated a significant separation of survival curves stratified by median value of LA strain (Figure).
Conclusions
LA dysfunction in HFpEF is associated with a higher risk of HF hospitalization, and LA strain measurements would be useful to predict HF events.
