Abstract
Recent studies revealed that a substantial proportion of patients with high-risk B-cell precursor acute lymphoblastic leukemia (BCP-ALL) harbor fusions involving tyrosine kinase and cytokine receptors, such as ABL1, PDGFRB, JAK2 and CRLF2, which are targeted by tyrosine kinase inhibitors (TKIs). In the present study, transcriptome analysis or multiplex reverse transcriptase–PCR analysis of 373 BCP-ALL patients without recurrent genetic abnormalities identified 29 patients with kinase fusions. Clinically, male predominance (male/female: 22/7), older age at onset (mean age at onset: 8.8 years) and a high white blood cell count at diagnosis (mean: 94 200/μl) reflected the predominance of National Cancer Institute high-risk (NCI-HR) patients (NCI-standard risk/HR: 8/21). Genetic analysis identified three patients with ABL1 rearrangements, eight with PDGFRB rearrangements, two with JAK2 rearrangements, three with IgH-EPOR and one with NCOR1-LYN. Of the 14 patients with CRLF2 rearrangements, two harbored IgH-EPOR and PDGFRB rearrangements. IKZF1 deletion was present in 16 of the 22 patients. The 5-year event-free and overall survival rates were 48.6±9.7% and 73.5±8.6%, respectively. The outcome was not satisfactory without sophisticated minimal residual disease-based stratification. Furthermore, the efficacy of TKIs combined with conventional chemotherapy without allogeneic hematopoietic stem cell transplantation in this cohort should be determined.

Abstract
OBJECTIVES To identify the relationships between physical and/or cognitive frailty and instrumental activities of daily living (IADL) functioning in community living older persons. DESIGN Cross sectional observation study. SETTING Data extracted from the 2011-2013 of the National Center for Geriatrics and Gerontology-Study of Geriatric Syndromes (NCGG-SGS) database. PARTICIPANTS A total of 8,864 older adults aged ≥ 65 years who were enrolled in the NCGG-SGS. MEASUREMENTS We characterized physical frailty as limitations in three or more of the following five domains: slow walking speed, muscle weakness, exhaustion, low activity and weight loss. To screen for cognitive impairment, we used the National Center for Geriatrics and Gerontology-Functional Assessment Tool (NCGG-FAT) which included tests of word list memory, attention and executive function (tablet version of the Trail Making Test, part A and B), and processing speed (tablet version of the Digit Symbol Substitution Test). Two or more cognitive impairments indicated by an age-adjusted score of at least 1.5 standard deviations below the reference threshold was characterized as cognitive impairment. Each participant reported on their IADL status (use of public transportation, shopping, management of finances, and housekeeping) and several potential confounders such as demographic characteristics. RESULTS The overall prevalence of physical frailty, cognitive impairment, and cognitive frailty, i.e. co-occurrence of frailty and cognitive impairment, was 7.2%, 5.2%, and 1.2%, respectively. We found significant relationships between IADL limitations and physical frailty (Odds Ratio (OR) 1.24, 95% confidence interval (95% CI) 1.01 to 1.52), cognitive impairment (OR 1.71, 95% CI 1.39 to 2.11), and cognitive frailty (OR 2.63, 95% CI 1.74 to 3.97). CONCLUSION Using the NCGG-SGS frailty criteria, we found more participants with physical frailty than with cognitive frailty. The individuals with cognitive frailty had the highest risks of IADL limitations. Future investigation is necessary to determine whether this population is at increased risk for incidence of disability or mortality.

Abstract
DNA-mediated immunization of a tumour antigen is a possible immunotherapy for cancer, and interleukin (IL)-27 has diverse functions in adaptive immunity. In this study, we examined whether IL-27 DNA administration enhanced antitumour effects in mice vaccinated with DNA encoding a putative tumour antigen, β-galactosidase (β-gal). An intramuscular injection of cardiotoxin before DNA administration facilitated the exogenous gene expression. In mice received β-gal and IL-27 DNA, growth of β-gal-positive P815 tumours was retarded and survival of the mice was prolonged. Development of β-gal-positive Colon 26 tumours was suppressed by vaccination of β-gal DNA and further inhibited by additional IL-27 DNA administration or IL-12 family cytokines. Nevertheless, a population of β-gal-specific CD8(+) T cells did not increase, and production of anti-β-gal antibody was not enhanced by IL-27 DNA administration. Spleen cells from mice bearing IL-27-expressing Colon 26 tumours showed greater YAC-1-targeted cytotoxicity although CD3(-)/DX5(+) natural killer (NK) cell numbers remained unchanged. Recombinant IL-27 enhanced YAC-1-targeted cytotoxicity of IL-2-primed splenic NK cells and augmented a phosphorylation of signal transducer and activator of transcription 3 and an expression of perforin. These data collectively indicate that IL-27 DNA administration activates NK cells and augments vaccination effects of DNA encoding a tumour antigen through non-adaptive immune responses.

Abstract
OBJECTIVE To investigate the diagnostic performance of brain acetylcholinesterase (AChE) activity measurement using N-[(11) C]-methyl-4-piperidyl acetate (MP4A) and PET in patients with dementia with Lewy bodies (DLB) and Alzheimer's disease (AD). METHODS Participants were 14 DLB patients, 25 AD patients and 18 age-matched healthy controls (HC). All subjects underwent PET scans and MP4A to measure regional brain AChE activity. We performed anatomical standardization of each brain image, and k3 values, an index of AChE activity, in each voxel were estimated by nonlinear least squares analysis. Volumes of interest (VOIs) were identified on parametric k3 images in frontal, temporal, parietal and occipital cortices, and in anterior and posterior cingulate gyri (ACG and PCG). In each VOI, the differential diagnostic performance between AD and DLB of k3 values was assessed by area under the curve (AUC) of the receiver-operating characteristic. Voxel-based statistical analyses were also performed. RESULTS Mean cortical AChE activities in AD patients (-8.2% compared with normal mean) and DLB patients (-27.8%) were lower than HCs (p < 0.05, p < 0.001, respectively). There was a significant difference in mean cortical AChE activities between AD and DLB patients (p < 0.001). All regional brain AChE activities of defined VOIs except ACG were able to well discriminate DLB from AD, and notably performance was the most significant in PCG (AUC = 0.989, 95% CI: 0.965-1.000). CONCLUSIONS Brain cholinergic deficit is consistently prominent in DLB compared with AD. PET measurement of brain AChE activity may be useful for the differential diagnosis between DLB and AD.

Abstract
BACKGROUND Clinical characteristics, management, and outcomes in hemodialysis patients with atrial fibrillation (AF) remain unclear. METHODS AND RESULTS We studied 423 Japanese patients undergoing maintenance hemodialysis (age 65.2±12.4 years, male 70%, mean duration of hemodialysis 139±124 months). AF was present in 19% (n=82) and was independently related to increased age (odds ratio 1.070, 95% confidence interval 1.043-1.098), longer hemodialysis duration (odds ratio 1.006, 95% confidence interval 1.004-1.008), and congestive heart failure (odds ratio 2.749, 95% confidence interval 1.546-4.891). During observations lasting a mean of 36 months, the incidences of all-cause death, cardiovascular death, and major bleeding, in particular gastrointestinal bleeding, were significantly higher in the AF (n=82) than the non-AF (n=341) patients (p<0.001, p=0.004, p=0.002, p=0.027, respectively), but the incidence of ischemic stroke/systemic embolism was similar in the AF and non-AF patients. AF was independently associated with all-cause death (hazard ratio 1.728, 95% confidence interval 1.123-2.660) and major bleeding (hazard ratio 1.984, 95% confidence interval 1.010-3.896). Warfarin was prescribed in 33% of the AF patients, but the rates of all-cause death, ischemic stroke, and major bleeding during the study period were not significantly different between warfarin (n=27) and non-warfarin (n=55) groups. CONCLUSIONS In our hemodialysis patients, AF was a common comorbidity and was independently associated with all-cause death and major bleeding, but not with increased risk of ischemic stroke.

Abstract
BACKGROUND Staff attitudes may affect choices available to persons with intellectual disabilities (ID). This study examined attitudes towards people with ID among staff working with people with ID in Japan and the United States. METHOD Attitudes of staff working with people with ID in Japan and the United States were compared using the Community Living Attitudes Scale, Intellectual Disabilities Form. Responses were examined via multivariate analysis of variance. RESULTS In unadjusted analyses, Japanese staff exhibited a greater tendency towards Sheltering and Exclusion of people with ID and lower endorsement of Empowerment and Similarity of people with ID. After controlling for covariates, the country effect was no longer significant for Sheltering and Exclusion. Age and education were significantly associated with attitudes in the adjusted model. CONCLUSIONS While attitudes in Japan appeared less supportive of community inclusion of people with ID, some of the differences between countries were attributable to other staff characteristics such as age and education. Findings provide new information about how attitudes of staff in each country compare with each other.

Abstract
UNLABELLED The present prospective follow-up study among 1,393 community-dwelling elderly women aged 75 years or older was conducted to clarify the association between serum 25-hydroxyvitamin D (25(OH)D) level and risk of falls. Lower serum 25(OH)D, particularly level <20 ng/mL, was significantly associated with an increased risk of falls. INTRODUCTION Serum 25(OH)D level has been revealed to be important factor not only for skeletal health but also for fall prevention among the elderly. Our previous cross-sectional study indicated that low serum 25(OH)D level is associated with inferior physical performance and falls among elderly Japanese women. The present prospective study was designed to clarify the association between serum 25(OH)D level and risk of falls before and after 1 year of follow-up. METHODS The community-dwelling elderly women aged 75 years or older (N = 1,393) who participated in a mass health examination were followed 1 year later by a mailed self-administered questionnaire. RESULTS Responses were obtained from 1,285 subjects (response rate = 92.2%). The incidence of falls at baseline and at 1-year follow-up was 18.8 and 24.4%, respectively. The baseline prevalence of serum 25(OH)D <20 ng/mL was 35.2%. Odds ratios (95% confidence intervals) in the lowest tertile of serum 25(OH)D (<20 ng/mL) compared with those in the highest tertile (≥25 ng/mL) were 1.40 (1.01-1.94) for any falls and 1.47 (0.93-2.32) for recurrent falls vs. no falls adjusted for potential risk factors. CONCLUSIONS Among elderly Japanese women, the lower serum 25(OH)D, particularly level <20 ng/mL, was significantly associated with an increased risk of falls.

Abstract
AIM The indications for intersphincteric (ISR) anterior resection are not clearly defined. The aim of this study was to evaluate vertical extension of T2 or T3 low rectal cancer treated by rectal amputation to optimize patient selection for ISR. METHOD The abdominoperineal excision specimens of T2 or T3 low rectal cancer from 53 patients treated between 1992 and 2004 were retrospectively reviewed. Vertical invasion was quantified by measuring the shortest distance between the tumour and the striated muscle (T-SM), assuming that this represented the surgical margin that would have be achieved had an ISR been performed. RESULTS Involvement of the dentate line (DL) and intramural distal spread were independent risk factors for T-SM ≤ 2 mm. The T-SM was less when the inferior border of the tumour was on the distal side of the DL (r = 0.572, P < 0.001). The probability of involvement of the DL, intramural distal spread or either one of these being associated with T-SM ≤ 2 mm was 43, 46 and 43%, respectively. All patients without both intramural distal spread and involvement of the DL had T-SM > 2. CONCLUSION We recommend that ISR should only be performed for patients with T2 or T3 low rectal cancer in whom the lowest edge of the tumour is above the DL and there is no intramural distal spread. Such patients are relatively unlikely to have a T-SM ≤ 2 mm.

Abstract
Far-upstream element-binding protein-interacting repressor (FIR) is a transcription factor that inhibits c-Myc expression and has been shown to have antitumor effects in some malignancies. Here, we evaluated the antitumor effects of FIR using fusion gene-deleted Sendai virus (SeV/ΔF) as a nontransmissible vector against head and neck squamous cell carcinoma (HNSCC). Using in vitro and in vivo xenograft mouse models, we observed efficient expression of green fluorescent protein (GFP) following transduction with the SeV/ΔF vector encoding GFP (GFP-SeV/ΔF) into HNSCC cells. In vitro and in vivo studies revealed that administration of the FIR-encoded SeV/ΔF (FIR-SeV/ΔF) vector exerted significant antitumor effects, suppressed c-Myc expression and induced apoptosis in HNSCC. Additionally, the antitumor effects of FIR or the expression of GFP following administration of the FIR- or GFP-SeV/ΔF vector, respectively, were dependent on the multiplicity of infection or titer. Furthermore, the SeV/ΔF vector itself had no cytotoxic effects. Therefore, the SeV/ΔF vector may be safe and useful for the treatment of HNSCC, allowing for high-titer SeV/ΔF vector administration for anticancer gene therapy. In addition, SeV/ΔF vector-mediated FIR gene therapy demonstrated effective tumor suppression in HNSCC, suggesting that this therapy may have the potential for clinical use as a novel strategy for HNSCC treatment.
