Abstract
OBJECTIVE To examine whether immersive virtual reality (VR) can improve balance, gait, mobility and fear of falling in older people. DATA SOURCES MEDLINE, EMBASE, CINAHL, PsycINFO, ProQuest Central (Engineering and Computer Science) and reference lists of included articles. STUDY SELECTION Randomised controlled trials that administered immersive VR training and assessed balance, gait and mobility outcomes in older adults without neurological disorders (mean age ≥ 65). Primary outcomes were standing balance (e.g. postural sway), multi-item balance scales (e.g. Berg Balance Scale), gait (e.g. gait speed) and mobility (e.g. Timed Up and Go test). Secondary outcomes comprised measures of enjoyment, fear of falling, adherence (e.g. dropout rate), feasibility/usability and adverse effects (e.g. motion sickness). RESULTS Meta-analyses showed that immersive VR training significantly improved standing balance (SMD: 0.51, 95% CI: .15, 0.86, p = 0.005, I2 = 28% - 3 studies, n = 79) and performance on the Berg Balance Scale (MD: 2.36, 95% CI: 1.17, 3.56, p=0.0001, I2=0% - 4 studies, n = 190). No significant improvement in gait, mobility or fear of falling was found. Subgroup analyses revealed higher training doses (≥4.5 total hours) and VR interventions using non-head mounted displays were more likely to improve standing balance. No meta-analyses were conducted for enjoyment, adherence, feasibility/usability and adverse events. CONCLUSIONS The findings indicate immersive VR has beneficial effects on balance, but not gait, mobility or fear of falling. Further research is required to examine these outcomes in trials that also include quantitative measurements of enjoyment, adherence, clinical feasibility, usability and adverse effects.

Abstract
OBJECTIVES Thoracic endovascular aortic repair (TEVAR) for aortic arch aneurysms is challenging because of anatomical restrictions and the presence of cervical branches. Revascularization of the cervical branch is required when conventional commercial stent grafts are used. TEVAR using fenestrated stent grafts (FSG) often does not require additional procedures to revascularize cervical branches. This study aimed to evaluate the features and initial and midterm outcomes of TEVAR using fenestrated stent grafts. METHODS From April 2007 to December 2016, 101 consecutive patients underwent TEVAR using fenestrated stent grafts for distal aortic arch aneurysms at a single centre. Technical success, complications, freedom from aneurysm-related death, secondary intervention and aneurysm progression were retrospectively investigated. RESULTS All the patients underwent TEVAR using fenestrated stent grafts. The 30-day mortality rate was zero. Cerebral infarction, access route problems and spinal cord injury occurred in 4, 3 and 2 patients, respectively. Each type of endoleak was observed in 38 of the 101 patients during the course of the study; 20/38 patients had minor type 1 endoleaks at the time of discharge. The endoleak disappeared in 2 patients and showed no significant change in 8 patients; however, the aneurysm expanded over time in 10 patients. Additional treatment was performed in 8 of the 10 patients with type 1 endoleaks and dilatation of the aneurysm. The rate of freedom from aneurysm-related death during the observation period was 98%. CONCLUSIONS TEVAR with FSG is a simple procedure, with few complications. Additional treatment has been observed to reduce aneurysm-related deaths, even in patients with endoleaks and enlarged aneurysms. Based on this study, the outcomes of endovascular repair of aortic arch aneurysms using a fenestrated stent graft seem acceptable.

Abstract
Effisayil 1 was a multicentre, randomized, double-blind, placebo-controlled study of the anti-interleukin (IL)-36 receptor monoclonal antibody, spesolimab, in patients presenting with a generalized pustular psoriasis (GPP) flare. Previously published data from this study revealed that within 1 week, rapid pustular and skin clearance were observed in patients receiving spesolimab versus placebo. In this pre-specified subgroup analysis, the efficacy of spesolimab was evaluated according to patient demographic and clinical characteristics at baseline in patients receiving spesolimab (n = 35) or placebo (n = 18) on Day 1. Efficacy was by assessed by achievement of primary endpoint (Generalized Pustular Psoriasis Physician Global Assessment [GPPGA] pustulation subscore of 0 at Week 1) and key secondary endpoint (GPPGA total score of 0 or 1 at Week 1). Safety was assessed at Week 1. Spesolimab was found to be efficacious and had a consistent and favourable safety profile in patients presenting with a GPP flare, regardless of patient demographics and clinical characteristics at baseline.

Abstract
BACKGROUND No easy-to-use fall risk assessment tools have been devised to assess occupational fall risk in older workers. AIMS To develop an Occupational Fall Risk Assessment Tool (OFRAT) and report its predictive validity and reliability in older workers. METHODS The baseline fall risk assessment was completed by 1113 participants aged ≥60 years who worked ≥4 days/month in Saitama, Japan. Participants were followed up for falls during occupational activities for 1 year, and 30 participants were assessed twice for test-retest reliability. The following assessment measures were summed to form the OFRAT risk score: older age, male sex, history of falls, physical work participation, diabetes, use of medications increasing fall risk, reduced vision, poor hearing, executive dysfunction and slow stepping. The scores were then classified into four grades (0-2 points: very low, 3 points: low, 4 points: moderate and ≥5 points: high). RESULTS During follow-up, 112 participants fell 214 times during work. The negative binomial regression model showed that participants with higher grades had a higher incidence rate ratio [95% confidence interval] for falls than those with very low grades (low: 1.64 [1.08-2.47], moderate: 4.23 [2.82-6.34] and high: 6.12 [3.83-9.76]). The intraclass correlation coefficient for risk score was 0.86 [0.72-0.93], and the weighted kappa coefficient for grade assessment was 0.74 [0.52-0.95]. CONCLUSIONS The OFRAT is a valid and reliable tool for estimating the occupational fall risk in older workers. It may assist occupational physicians implement strategies to prevent falls in this group.

Abstract
BACKGROUND The Japanese government introduced financial incentives to reduce nationwide antibiotic use in hospital settings. AIM This study aimed to determine whether the nationwide financial incentives for creating infection prevention and control (IPC) teams introduced in 2012 and antimicrobial stewardship (ASP) teams introduced in 2018 were associated with changes in antibiotic use and health resource utilization at a national level. METHODS We conducted time-series analyses and a difference-in-differences study consisting of 3,057,517 inpatients with infectious diseases from 472 medical facilities during fiscal years 2011-2018 using a nationally representative inpatient database in Japan. The primary outcome was the days of therapy (DOT) of antibiotic use per 100 patient-days (PDs). The secondary outcomes consisted of types of antibiotic used, health resource utilization, and mortality. RESULTS A total of 5,201,304 financial incentives were observed during 2012-2018, which resulted in a total of 12.1 billion JPY (≈110 million USD). Time-series analyses found decreasing trends in total antibiotic use (79.3-72.5 DOTs/100 PDs (8.6% reduction)) and carbapenem use (9.0-7.0 DOTs/100 PDs (7.8% reduction)) from 2011 to 2018 without adversely affecting other healthcare outcomes (e.g., mortality). In the difference-in-differences analyses, we did not observe meaningful changes in total antibiotic use between the incentivized and unincentivized hospitals for ASP teams, except for the northern part of Japan. No dose-response relationships were observed between the amount of financial incentives and reductions in antibiotic use during 2011-2019. CONCLUSIONS Further research and efforts are needed to accelerate antimicrobial stewardship in hospital settings in Japan.

Abstract
BACKGROUND The risk of thrombus development is considered to be increased by malignant tumors and chemotherapy. In addition, thrombosis of the ascending aorta is rare. We report a case of ascending aortic thrombectomy in a patient with esophageal cancer who developed ascending aortic thrombus after starting neoadjuvant chemotherapy, including operative findings and surgical treatment. CASE PRESENTATION A 63-year-old man with esophageal cancer was administered chemotherapy comprising cisplatin plus 5-fluorouracil. A week after completing 1 cycle of chemotherapy, computed tomography angiography showed acute aortic thrombosis at the ascending aorta. The risk of embolization appeared high because the thrombosis was floating, so we performed emergency ascending aortic thrombectomy. The postoperative course was good and uncomplicated. A month after this surgery, the patient underwent surgery for esophageal cancer. As of 1 year after the cancer surgery, neither cancer nor thrombosis has recurred. CONCLUSION We describe a case of acute aortic thrombosis in the ascending aorta after cisplatin-based chemotherapy, that was treated by aortic thrombectomy. The treatment strategy should depend on thrombus location and the condition of the patient, but surgical treatment should be considered where possible to achieve better prognosis.

Abstract
BACKGROUND People with Parkinson's disease (PD) have difficulties adapting their gait. While underlying neural mechanisms involving the prefrontal cortex (PFC) have been studied across various complex walking tasks, less is known about the premotor cortex (PMC) and supplementary motor area (SMA), key cortical regions for motor planning. This study compared frontal cortical regions activation patterns using functional near-infrared spectroscopy (fNIRS), between people with PD and healthy controls (HC) during gait adaptability tasks. METHODS Forty-nine people with PD (mean (SD) age: 69.5 (7.9) years) and 21 HC (69.0 (5.9) years) completed a simple walk and three randomly presented gait adaptability tasks: (i) stepping on targets, (ii) avoiding obstacles and (iii) negotiating both targets and obstacles. Cortical activity in the dorsolateral PFC (DLPFC), SMA and PMC were recorded using fNIRS. Step length, velocity and accuracy and cortical activity were contrasted between the groups and walking conditions. RESULTS Compared with the HC, the PD group exhibited greater PMC activation and walked significantly slower and took shorter steps in all conditions. A statistically significant group by condition interaction indicated an increase in DLPFC cortical activation in the HC participants when undertaking the obstacle avoidance task compared with the simple walk but no increase in cortical activation in the PD group when undergoing this more challenging gait task. CONCLUSIONS Our findings suggest people with PD have little or no DLPFC, SMA and PMC capacity beyond what they need for simple walking and in consequence need to slow their gait velocity to meet the demands of target stepping and obstacle avoidance tasks. Such behavioral and neural patterns appear consistent with concepts of compensatory over-activation and capacity limitation.

Abstract
INTRODUCTION Solitary fibrous tumour (SFT) is a rare mesenchymal tumour with intermediate malignant potential. Although this tumour arises in several sites, prostatic SFT is an extremely rare neoplasm and may prove confusing owing to the lack of clinical experience because of tumour rarity. The diagnosis may be further difficult because SFTs can manifest positive immunoreactivity for CD34 and progesterone receptor, which are known markers of prostatic stromal tumours. Herein, we describe a case of prostatic SFT that was difficult to differentiate from a prostatic stromal tumour of uncertain malignant potential because of positive immunoreactivity to CD34 and progesterone receptor. CASE REPORT A 40-year-old Japanese man presented with lower abdominal pain. Computed tomography revealed a prostatic mass; furthermore, prostate core needle biopsy revealed proliferating bland spindle cells, without necrosis or prominent mitoses. Tumour cells were positive for CD34 and progesterone receptor on immunohistochemical analysis; thus, a prostatic stromal tumour of uncertain malignant potential was initially suspected. However, as the tumour cells showed positive immunoreactivity for STAT6, the final diagnosis was an SFT of the prostate. The patient underwent tumour resection, and at the 6-month postoperative follow-up, neither local recurrence nor distant metastasis occurred. CONCLUSION For an accurate diagnosis of an SFT of the prostate, STAT6 immunohistochemistry should be conducted for all mesenchymal tumours of the prostate. When STAT6 immunohistochemical analysis is unfeasible, pathologists should be aware that the morphological and immunohistochemical characteristics of SFT variable from case to case and diagnose with combined analysis of several immunohistochemical markers.

Abstract
Impaired mobility often co-occurs with depression. However, there is no systematic review evidence as to whether mobility impairments precede the onset of depression. The objective of this systematic review and meta-analysis was to evaluate whether mobility impairment could predict incident depression. A systematic search of cohort studies were performed in MEDLINE, EMBASE, CINAHL and PsycINFO. The target population was people with no depressive symptoms at baseline and follow-up for depression or depressive symptoms of at least three months. Of 1061 identified abstracts, 13 studies met the review eligibility criteria. The majority of included studies (8 out of 13) were of high methodological quality. Follow-up periods ranged from 12 months to 16 years. Gait speed was the most consistently reported mobility measure. Participants with slow gait speed were at higher risk of developing depressive symptoms (pooled OR = 1.93, 95%CI: 1.54 to 2.42, 11 studies). This review shows that slow gait speed is predictive of the onset of depressive symptoms. Systematic review registration number: CRD42020153791.

Abstract
BACKGROUND With the increasing use of biological agents for the treatment of psoriasis, the numbers of patients with interstitial lung disease (ILD) associated with biologics have also increased. Many of these cases were associated with tumour necrosis factor (TNF)-α inhibitors, but cases associated with other families of biologics have also been reported in Japan. AIM To analyse the background factors of patients who developed ILD, and to discuss better management of biological treatment. METHOD We reviewed 246 patients with psoriasis who were treated with biological agents in our department to identify any pulmonary adverse events (AEs). Data on patients who developed ILD were extracted to analyse background factors, clinical type of psoriasis, time to onset of ILD, pre-existing ILD, smoking habit and prescribed drugs. RESULTS Pulmonary AEs were seen in 22 cases, of which 11 were diagnosed as drug-induced ILD. The causative drugs were mainly TNF-α inhibitors, accounting for eight cases (six treated with infliximab, two with adalimumab). The remaining three cases were associated with secukinumab, ustekinumab and ixekizumab (n = 1 each). Notably, these three cases also had a history of drug-induced ILD. CONCLUSION Patients with a history of drug-induced ILD seem to be more susceptible to developing another ILD induced by biologics, even if treated with interleukin-17 inhibitors. Thorough screening of risk factors and evaluation for eligibility, and careful monitoring during treatment are the best solutions to avoid serious pulmonary AE. Early detection and precise diagnosis of pulmonary AEs, especially differentiation from infectious diseases, is essential for managing biological treatment.

Abstract
BACKGROUND Palmoplantar pustulosis (PPP) is a distinct, chronic skin disorder characterized by intraepidermal pustules on the palms and soles. It is hypothesized that microorganisms on the skin might induce the symptoms of PPP via inflammatory cell activation. However, the microbiota has not been studied in detail because of the assumption that the pustules in PPP are sterile. AIM To elucidate the role of microorganisms in pathogenesis of PPP. METHODS PCR analysis was performed of microbial DNA fragments in the pustules of patients with PPP. The sequence of the D1/D2 LSU 26s rRNA gene and that of the 16S rRNA gene was used for fungal and bacterial DNA detection, respectively. RESULTS In total, 71 samples were carefully collected from the pustules of patients with PPP. Fungal DNA bands were detected in 68 samples, and fungi including Malassezia spp. were identified in 30 of 71 samples (42.3%). Malassezia restricta was the most frequently encountered fungus (14/71; 19.7%). However, bacterial DNA was not detected by the methods used. Furthermore, identical fungal DNA was not detected in the outer lid of the pustules, suggesting that the fungi detected within the pustule did not derive from contamination via the skin surface. CONCLUSIONS In the present study, we demonstrated for the first time that certain pustules in patients with PPP contain fungal DNA fragments, especially those of Malassezia spp. Our findings provide new insights on the role of skin microbiota in the pathogenesis of PPP.

Abstract
Background Erythrodermic and generalized pustular psoriasis are rare, difficult to treat forms of psoriasis. In previous reports, we documented 24‐ and 52‐week findings of an open‐label, phase 3 trial (UNCOVER‐J) of ixekizumab in Japanese patients with erythrodermic or generalized pustular psoriasis; most patients responded to treatment and maintained response through 52 weeks. Objective To assess the long‐term (>3 years) efficacy and safety of ixekizumab in Japanese patients with erythrodermic or generalized pustular psoriasis. Methods These subgroup analyses were of a partial population of patients from UNCOVER‐J (NCT01624233; Sponsored by Eli Lilly and Company), specifically those with erythrodermic psoriasis (N = 8) or generalized pustular psoriasis (N = 5). These patients received 160 mg ixekizumab at Week 0, ixekizumab 80 mg every 2 weeks through Week 12, and ixekizumab 80 mg every 4 weeks thereafter up to Week 244. This regimen is consistent with the regimen approved in Japan for plaque, erythrodermic, and generalized pustular psoriasis and psoriatic arthritis. Efficacy assessments included Global Improvement Score (GIS), Psoriasis Area and Severity Index (PASI), dermal symptoms (for patients with generalized pustular psoriasis), Dermatology Life Quality Index (DLQI) and Itch Numeric Rating Scale (NRS). Safety assessments included treatment‐emergent adverse events and adverse events of special interest. Results Most patients had a GIS of resolved or improved from Week 12 onwards, and all patients had early and sustained improvement in PASI and dermal symptom (generalized pustular psoriasis only) scores. Mean improvements in DLQI and Itch NRS at Week 12 were sustained through Week 244. Ixekizumab was well tolerated over 3 years of treatment in patients with erythrodermic psoriasis or generalized pustular psoriasis, and no new safety concerns were identified. Conclusion These findings suggest that ixekizumab can be an effective long‐term treatment option for erythrodermic or generalized pustular psoriasis. Linked article: This article is commented on G.

Abstract
OBJECTIVE Develop and evaluate the feasibility and validity of the Nutrition and Functionality Assessment (NFA) which identifies "target" older adults who could benefit from a personalized program following evaluation of their nutrition status and physical functionality. DESIGN Cross-sectional study. SETTING Community and geriatric day-care centers and university in Japan. PARTICIPANTS 267 older adults aged 65-90. MEASUREMENTS The "target" individuals were screened based on gait speed (0.6-1.5 m/s). Nutrition (Mini Nutrition Assessment-short form and protein intake), strength (30s chair sit-to-stand and hand-grip strength) and endurance (6-minute walk) were assessed. Physical activity was monitored using a tri-axil accelerometer for a week. Fried frailty phenotype was also assessed. RESULTS Out of 267 individuals, 185 (69%) had gait speed between 0.6-1.5 m/s, corresponding to our "target" group from which, 184 (95%) completed the nutrition and physical functionality assessments with the physical activity monitoring. The NFA was completed in approximately 30 minutes. No adverse events directly due to the NFA were reported. NFA physical functionality and global scores were significantly related to frailty phenotype but nutrition score was not related to frailty phenotype. CONCLUSION The study demonstrated that the NFA is a safe and feasible tool to screen target older adults and simultaneously evaluate their nutritional status and physical functionality. Validity of the NFA was partially confirmed by the significant association of the global and physical functionality scores with frailty phenotype. More studies are required to validate and maximize the applicability of the NFA in communities and institutions in Japan and elsewhere.

SummaryPatterns of VIIIR:AG in the plasma and its fractions, cryoprecipitate and cryosupernatant, from various types of von Willebrand’s disease (vWd) were observed by SDS 1.5% polyacrylamide gel electrophoresis - crossed immunoelectrophoresis (SDS PAGE - CIE).
VIIIR:AG in normal cryoprecipitate showed several precipitin peaks which correspond to molecular weights ranging from 8 X 105 to 1 X 10
7 daltons and are similar to those in normal plasma. Normal cryosupernatant VIIIR: AG gave smaller molecular weights from 8 X 10
5 to 2 X 10
6 daltons.VIIIR:AG in the plasma and cryoprecipitate from 2 patients with classical vWd gave low precipitin peaks with molecular weights in normal range. VIIIR:AG from 2 patients with subgroup A variant which showed fast anodal migration on the conventional CIE, presented 3 peaks with molecular weights of 8 X 105 to 3 X 106 which are similar to those in normal cryosupernatant. VIIIR: AG from 2 patients with subgroup B variant which showed normal migration on the CIE, gave normal patterns through all fractions.

Abstract
Abstract:This paper compares two classifiers: Pseudo Bayesian and Neural Network for assisting in making diagnoses of psychiatric patients based on a simple yes/no questionnaire which is provided at the outpatient’s first visit to the hospital. The classifiers categorize patients into three most commonly seen ICD classes, i.e. schizophrenic, emotional and neurotic disorders. One hundred completed questionnaires were utilized for constructing and evaluating the classifiers. Average correct decision rates were 73.3% for the Pseudo Bayesian Classifier and 77.3% for the Neural Network classifier. These rates were higher than the rate which an experienced psychiatrist achieved based on the same restricted data as the classifiers utilized. These classifiers may be effectively utilized for assisting psychiatrists in making their final diagnoses.

Abstract
A 70-year-old man presented to our clinic with a 10-year history of recurrent pruritic erythema and plaques on his trunk and limbs. Based on the pathological findings and monoclonal rearrangement of the T-cell receptor (TCR)-Cβ1 gene, mycosis fungoides (T2N0M0B0 stage IB) was diagnosed. Despite combination therapy including histone deacetylase inhibitor (vorinostat), the symptoms slowly evolved into Sézary syndrome (SS; T4N1M0B2) over 4 years, with dense infiltrates due to atypical lymphocytes expressing CCR4 developing in the entire dermis. Anti-CCR4 monoclonal antibody (mogamulizumab) treatment was started. After seven courses, the CCR4-positive atypical lymphocytes decreased in the dermis to levels below those seen at the outset of treatment. To our knowledge, there is no previous report of a case of SS managed with vorinostat followed by mogamulizumab demonstrating such a remarkable change in the pathological state following treatment.

Abstract
Background Appropriate goal‐oriented treatment strategies are important for optimal treatment outcomes and may prevent under‐treatment. As treatment goals vary by patient, a study to examine treatment goals is more meaningful when patients and their physicians are paired. There has not been any study that examines alignment between paired psoriasis patients and physicians in real‐world clinical practice using skin clearance as a treatment goal indicator. Objectives To evaluate treatment goal alignment between psoriasis patients and their paired physicians, and to quantitatively identify factors associated with goal misalignment. Methods The study was a nationwide multicenter cross‐sectional observational study. Subjects were physician‐reported moderate‐to‐severe psoriasis patients with a history of systemic treatments, directly paired with their treating physicians. Subjects completed surveys independently. Treatment goals included seven categories, and patient–physician pairs were grouped as ‘aligned’ or ‘misaligned’ when the answers were the same or different, respectively. Results A total of 425 pairs (mean response rate, 94.7%) of responses were collected from 54 sites (64.8% general practitioners or clinics; 35.2% university or large hospitals). Treatment goal misalignment was found in 67.9% of the patient–physician pairs. The misalignment was mainly ‘patient predominant’ (60.9%) indicating that patients had higher goals (‘complete clearance’) than physicians. In the multivariate logistic regression analyses, patients’ treatment expectation for ‘complete clearance’ [odds ratio (OR): 1.927; 95% confidential interval (CI): 1.232–3.016] and physician rating of ‘level of understanding on treatment options’ being low (OR: 1.552, 95% CI; 1.082–2.227) were significant factors for treatment goal misalignment. Conclusions The majority of treatment goal misalignment was found between paired psoriasis patients and their treating physicians in Japan. The most important contributing factors to misalignment were patients’ treatment expectation for ‘complete clearance’ and physicians’ rating of their patients’ ‘level of understanding on treatment options’ being low.

Abstract
BACKGROUND Palmoplantar psoriasis has significant physical and emotional impact on patients and can be difficult to treat. OBJECTIVE To evaluate the efficacy of ixekizumab in the treatment of patients with moderate-to-severe plaque psoriasis and moderate-to-severe non-pustular palmoplantar involvement. METHODS In three phase 3, double-blind, placebo-controlled trials, patients with moderate-to-severe non-pustular plaque psoriasis [UNCOVER-1 (N = 1296), UNCOVER-2 (N = 1224), UNCOVER-3 (N = 1346)] were randomized to subcutaneous 80 mg ixekizumab every 2 or 4 weeks (Q2W, Q4W), after a 160-mg starting dose, or placebo through week 12. Additional UNCOVER-2 and UNCOVER-3 cohorts were randomized to 50 mg etanercept biweekly. Patients entering the open-label long-term extension (UNCOVER-3) received ixekizumab Q4W weeks 12-60. Moderate-to-severe palmoplantar involvement was defined as Palmoplantar Psoriasis Area and Severity Index (PPASI) ≥8. RESULTS Twenty-eight percent of UNCOVER-1, UNCOVER-2 and UNCOVER-3 patients had baseline palmoplantar involvement (PPASI ≥0, n = 1092) and 9.1% (n = 350) had moderate-to-severe involvement, with mean baseline PPASI ~20, PASI ~24, and most (>60%) had static Physician's Global Assessment ≥4. Higher percentages of patients treated with ixekizumab vs. placebo or etanercept achieved PPASI 50 (approximately 80% vs. 32.9%, 67.8%; ixekizumab, placebo, etanercept, respectively) and PPASI 75 (approximately 70% vs. 18.8%, 44.1%; ixekizumab, placebo, etanercept, respectively) at week 12 (all P < 0.05). PPASI 100 was achieved by higher percentages of ixekizumab-treated patients vs. placebo (approximately 50% vs. 8.2%, P < 0.001) and ixekizumab Q2W-treated patients vs. etanercept (51.8% vs. 32.2%, P < 0.05). Outcomes were maintained or improved in patients continuing on ixekizumab Q4W through week 60. Differences between ixekizumab and placebo or etanercept were statistically significant as early as week 1. CONCLUSION In a subpopulation analysis of patients from phase 3 trials with moderate-to-severe non-pustular palmoplantar involvement and moderate-to-severe plaque psoriasis, ixekizumab treatment resulted in greater and more rapid improvements than placebo and etanercept at week 12; improvements were sustained with continued treatment.

Abstract
A 77-year-old woman developed dyspnea over three years which occurred during sitting, standing or walking. Her physical examination, chest X-ray, ECG and cardiac catheterization results were all normal. A marked fall in arterial oxygen saturation was observed on sitting or standing. Transesophageal echocardiography showed an increase of right to left shunt flow on sitting. The patient was diagnosed with platypnea-orthodeoxia syndrome and underwent the surgical closure of an atrial septal defect of 19 mm in diameter. After the surgery, the patient's POS symptoms were completely resolved. She was discharged and followed at the outpatient clinic. Her post-treatment course was uneventful.

Abstract
We carried out a retrospective evaluation of the early and long-term outcomes of aortic root reconstruction for type A acute aortic dissection. Between January 2001 and March 2015, a total of 21 patients underwent aortic root reconstruction. Bentall operation was performed in 9 patients( B group) and Patch plasty of sinus of Valsalva patients was performed in 12 patients (V group). There were 3 in-hospital deaths due in the B group and 1 death due in the V group. Overall survival in the V group was 72.9% and was not significantly different from survival in the B group(66.7%). In conclusion, our study demonstrated good early and long-term outcomes for patch plasty of sinus of Valsalva for type A acute aortic dissection. There was no postoperative patch-related complication in the V group. Thus, a patch plasty of sinus of Valsalva for type A acute aortic issection may be acceptable.

Abstract
OBJECTIVES To examine the combined association of obesity and low muscle strength with mobility limitation in older adults. DESIGN, SETTING AND PARTICIPANTS This two-year follow-up longitudinal study included pooled data from 283 older community-dwelling Japanese women without mobility limitations who were 65 to 87 years of age (mean age 72.2 ± 5.0 years). MEASUREMENTS Muscle strength was measured by hand-grip strength (HGS). The participants were categorized by HGS (high muscle strength: HGS ≥19.6 kg, low muscle strength: HGS <19.6 kg) and body mass index (BMI) (obese: BMI ≥25 kg/m2, normal weight: BMI <25 kg/m2). The main outcome was mobility limitation, assessed by a self-reported questionnaire (difficulty walking one-half mile or climbing 10 steps without resting). Multivariate logistic regression analysis was performed to determine the combined effect of HGS and BMI on mobility limitation, adjusting for age, exercise habits, medications, and knee pain. RESULTS During the follow-up period, 82 of 283 participants (29.0%) developed mobility limitation. The adjusted odds ratios (95% confidence interval) for the incidence of mobility limitation were 1.53 (0.86-2.73) and 2.05 (1.08-3.91) in the obese and low muscle strength groups, respectively. Obesity combined with low muscle strength exhibited a significant and strong association with mobility limitation (odds ratio: 3.88, 1.08-13.91) compared with participants with normal weight and high muscle strength. CONCLUSION Among community-dwelling older Japanese women, obesity alone was not associated with the incidence of mobility limitation, but when combined with low muscle weakness, the risk of developing mobility limitation was 3.9-fold greater than for the reference group.

Abstract
The aim of this study was to investigate the immediate effects of trunk stabilization exercise (SE) and conventional trunk exercise (CE) programs on jump performance. 13 adolescent male soccer players performed 2 kinds of jump testing before and immediate after 3 experimental conditions: SE, CE, and non-exercise (NE). The SE program consisted of the elbow-toe, hand-knee, and back bridge, and the CE program consisted of the sit-up, sit-up with trunk rotation and back extension. Testing of a countermovement jump (CMJ) and rebound jump (RJ) were performed to assess jump performance. Jump height of the CMJ and RJ-index, contact time, and jump height of the RJ were analyzed. The RJ index was improved significantly only after SE (p=0.017). However, contact time and jump height did not improve significantly in the SE condition. Moreover, no significant interaction or main effects of time or group were observed in the CMJ. Consequently, this study showed the different immediate effect on the RJ between the SE and CE, and suggested the possibility that the SE used in this study is useful as a warm-up program to improve the explosive movements.

Abstract
After the Chernobyl Nuclear Power Plant accident, the residents living around the Chernobyl were revealed to have been internally exposed to 137Cs through the intake of contaminated local foods. To evaluate the current situation of internal 137Cs exposure and the relationship between the 137Cs soil contamination and internal exposure in residents, we investigated the 137Cs body burden in residents who were living in 10 selected cities from the northern part of the Zhitomir region, Ukraine, and collected soil samples from three family farms and wild forests of each city to measured 137Cs concentrations. The total number of study participants was 36,862, of which 68.9% of them were female. After 2010, the annual effective doses were less than 0.1 mSv in over 90% of the residents. The 137Cs body burden was significantly higher in autumn than other seasons (p < 0.001) and in residents living in more contaminated areas (p < 0.001). We also found a significant correlation between the proportion of residents in each city with an estimated annual exposure dose exceeding 0.1 mSv and 137Cs concentration of soil samples from family farms (r = 0.828, p = 0.003). In conclusion, more than 25 years after the Chernobyl accident, the internal exposure doses to residents living in contaminated areas of northern Ukraine is limited but still related to 137Cs soil contamination. Furthermore, the consumption of local foods is considered to be the cause of internal exposure.

Abstract
We report herein a rare case of endocardial blood cyst (EBC) in an adult patient. A 63-year-old asymptomatic woman underwent echocardiography, which incidentally detected a cardiac tumor in the right atrium. On echocardiography, the tumor was revealed to be a 30-mm round mass with thin, hyperechogenic walls and heterogeneously hypoechogenic contents. The lesion was attached to the septum. On computed tomography, the tumor appeared partly calcified and showed poor contrast-enhancement. On magnetic resonance imaging, the lesion appeared isointense or slightly hyperintense in T1 and T2-weighted sequences. Myxoma was strongly suspected based on these preoperative imaging findings. The tumor was successfully excised under cardiopulmonary bypass. Gross examination confirmed that the cyst was filled with blood. The cystic walls comprised thin-layered fibrous tissue lined with endocardial cells. No tumor cells were found. The diagnosis of EBC was confirmed based on histopathological examination, and the postoperative course was uneventful.

Abstract
C-type natriuretic peptide (CNP) is a potent stimulator of long bone and vertebral development via endochondral ossification. In the present study, we investigated the effects of CNP on craniofacial skeletogenesis, which consists of both endochondral and membranous ossification. Morphometric analyses of crania from CNP knockout and transgenic mice revealed that CNP stimulates longitudinal growth along the cranial length, but does not regulate cranial width. CNP markedly increased the length of spheno-occipital synchondrosis in fetal murine organ cultures, and the thickness of cultured murine chondrocytes from the spheno-occipital synchondrosis or nasal septum, resulting in the stimulation of longitudinal cranial growth. Mandibular growth includes endochondral and membranous ossification; although CNP stimulated endochondral bone growth of condylar cartilage in cultured fetal murine mandibles, differences in the lengths of the lower jaw between CNP knockout or transgenic mice and wild-type mice were smaller than those observed for the lengths of the upper jaw. These results indicate that CNP primarily stimulates endochondral ossification in the craniofacial region and is crucial for midfacial skeletogenesis.
