Abstract
We retrospectively analysed 30-day mortality and duration of intubation for 8016 children ventilated for three or more days, sedated with midazolam (n = 7716) or propofol (n = 300). We matched the propensity scores of 263 pairs of children. The propensity-matched 30-day mortality (95% CI) was similar: 17/263 (6.5%) with midazolam vs. 24/263 (9.1%) with propofol, p = 0.26. Weaning from mechanical ventilation of children sedated with midazolam was slower than weaning of children sedated with propofol, subhazard ratio (95% CI) 1.43 (1.18-1.73), p < 0.001.

Abstract
SETTING A commercial serodiagnostic kit for diagnosing pulmonary disease due to Mycobacterium avium complex (MAC-PD) was developed and launched in Japan in 2011. OBJECTIVE To evaluate the performance of this kit in routine clinical settings. METHODS In this retrospective single-centre study, data on serum levels of anti-glycopeptidolipid (GPL) core IgA antibody (U/ml) measured using the kit were analysed in patients diagnosed with MAC-PD according to American Thoracic Society criteria, in those with pulmonary tuberculosis (PTB) or pulmonary M. kansasii disease and in healthy volunteers. RESULTS The anti-GPL-core IgA antibody levels of serum were significantly higher (P < 0.0001) in patients with MAC-PD (n = 485) than in those with PTB (n = 133) or pulmonary M. kansasii disease (n = 23) or in healthy subjects (n = 265). When the cut-off level was set at 0.7 U/ml, the sensitivity and specificity were respectively 78.6% and 96.9%. Higher antibody levels were observed in patients with greater extent of disease on chest computed tomography (P < 0.0001). CONCLUSIONS The serodiagnostic kit revealed good sensitivity and specificity. The antibody levels may reflect disease activity. Additional work is needed to determine whether the diagnostic assay could be used in conjunction with current diagnostic criteria to improve the diagnosis of MAC-PD.

Abstract
BACKGROUND Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic small-vessel vasculitis associated with asthma, eosinophilia, and necrotizing vasculitis. EGPA is potentially life-threatening and often involves peripheral neuropathies, peptic ulcers, cerebral vessel disease, and cardiovascular disease. However, there is limited understanding of the prognostics factors for patients with EGPA. We investigated the clinical features and factors affecting patients' in-hospital mortality, using a national inpatient database in Japan. METHODS We retrospectively collected data of EGPA patients who required hospitalization between July 2010 and March 2013, using the Diagnosis Procedure Combination database. We evaluated EGPA patients' characteristics and performed multivariate logistic regression analyses to assess the factors associated with in-hospital mortality. RESULTS A total of 2195 EGPA patients were identified. The mean age was 61.9 years, 42.1% (924/2195) were male, and 41.6% (914/2195) had emergent admission. In-hospital deaths occurred in 97/2195 patients (4.4%). Higher in-hospital mortality was associated with age older than 65 years, disturbance of consciousness on admission, unscheduled admission, respiratory disease, cardio-cerebrovascular disease, renal disease, sepsis, and malignant disease on admission. Lower mortality was associated with female gender and peripheral neuropathies. CONCLUSIONS Our study revealed the clinical features of EGPA patients who required hospitalization and the factors associated with their mortality. These results may be useful for physicians when assessing disease severity or treatments for hospitalized EGPA patients.

Abstract
We examined genetic and epigenetic changes that occur during disease progression from indolent to aggressive forms of chronic lymphocytic leukemia (CLL) using serial samples from 27 patients. Analysis of DNA mutations grouped the leukemia cases into three categories: evolving (26%), expanding (26%) and static (47%). Thus, approximately three-quarters of the CLL cases had little to no genetic subclonal evolution. However, we identified significant recurrent DNA methylation changes during progression at 4752 CpGs enriched for regions near Polycomb 2 repressive complex (PRC2) targets. Progression-associated CpGs near the PRC2 targets undergo methylation changes in the same direction during disease progression as during normal development from naive to memory B cells. Our study shows that CLL progression does not typically occur via subclonal evolution, but that certain CpG sites undergo recurrent methylation changes. Our results suggest CLL progression may involve developmental processes shared in common with the generation of normal memory B cells.

Abstract
Dual-gated PbS nanocrystal field-effect transistors employing SiO2 and Cytop as gate dielectrics are fabricated. The obtained electron mobility (0.2 cm(2) V(-1) s(-1) ) and the high on/off ratio (10(5) -10(6) ), show that the controlled nanocrystal assembly (obtained with self-assembled monolayers), as well as the trap density reduction (using Cytop as dielectric), are crucial steps for the future application of nanocrystals.

Abstract
Daclatasvir (DCV) and asunaprevir (ASV) are NS5A and NS3 protease-targeted antivirals respectively, currently under development for the treatment of chronic hepatitis C virus (HCV) infection. We analysed the relationship between pre-existing drug-resistant variants and clinical outcome of the combination treatment with DCV and ASV. Ten patients with HCV genotype 1b were orally treated with a combination of ASV and DCV for 24 weeks. The frequencies of amino acid (aa) variants at NS3 aa positions 155, 156 and 168 and at NS5A aa31 and 93 before and after treatment were analysed by ultra-deep sequencing. We established a minimum variant frequency threshold of 0.3% based on plasmid sequencing. Sustained virological response (SVR) was achieved in 8 out of 10 patients (80%), and relapse of HCV RNA after cessation of the treatment and viral breakthrough occurred in the other two patients. Pre-existing DCV-resistant variants (L31V/M and/or Y93H; 0.9-99.4%) were detected in three out of eight patients who achieved SVR. Pre-existing DCV-resistant variants were detected in a relapsed patient (L31M, Y93H) and in a patient with viral breakthrough (Y93H); however, no ASV-resistant variants were detected. In these patients, HCV RNA rebounded with ASV- and DCV- double resistant variants (NS3 D168A/V plus NS5A L31M and Y93H). While pre-existing DCV-resistant variants might contribute to viral breakthrough in DCV and ASV combination therapy, the effectiveness of prediction of the outcome of therapy based on ultra-deep sequence analysis of pre-existing resistant variants appears limited.

Abstract
BACKGROUND The association between recombinant human soluble thrombomodulin (rhTM) use and mortality in patients with sepsis-associated disseminated intravascular coagulation (DIC) remains controversial. OBJECTIVES To examine the hypothesis that rhTM could be effective in the treatment of patients with sepsis-associated DIC following severe pneumonia. METHODS Propensity score and instrumental variable analyses using a nationwide administrative database, the Japanese Diagnosis Procedure Combination inpatient database, were used. The main outcome was 28-day in-hospital all-cause mortality. RESULTS Eligible patients (n = 6342) from 936 hospitals were categorized into the rhTM group (n = 1280) or control group (n = 5062). Propensity score matching created a matched cohort of 1140 pairs with and without rhTM. No significant difference in 28-day mortality was documented between the two groups in the unmatched analysis (rhTM vs. control, 37.0%, 474/1280 vs. 36.9%, 1866/5062; odds ratio [OR], 1.00; 95%CI, 0.98-1.03), nor in the propensity-matched analysis (37.6%, 429/1140 vs. 37.0%, 886/1140; OR, 1.01; 95%CI, 0.93-1.10). The logistic regression analysis did not show a significant association between the use of rhTM and 28-day mortality in propensity-matched patients (OR, 1.00; 95%CI, 0.87-1.22). An analysis using the hospital rhTM-prescribing rate as an instrumental variable found that receipt of rhTM was not associated with reduction in mortality at 28 days (risk difference, 0.008; 95% CI, -0.08-0.98). CONCLUSIONS This large retrospective nationwide study demonstrated that there might be little association between the use of rhTM and mortality in severe pneumonia patients with sepsis-associated DIC. A multinational randomized trial is required to confirm this.

Abstract
A 47-year-old woman with pancytopenia, excessive systemic lymphadenopathy and splenomegaly was referred to our hospital. The peripheral blood (PB) smear findings indicated neutropenia with lymphoid cells exhibiting hairy projections, while the histological findings of the cervical lymph node (LN) suggested hairy cell leukemia (HCL). In addition, the BRAF V600E mutation was detected, and the immunoglobulin gene rearrangement patterns were identical in both the cervical LN and PB specimens. Based on these findings, we diagnosed the patient with systemic lymphadenopathy due to HCL. This is the first report of a BRAF mutation detected in both the PB and LN at the onset of HCL.

Hall effect and slightly negative temperature dependence of the mobility in polymeric transistors are demonstrated. The semiconductor channel is based on a polycyclopentadithiophene-benzothiadiazole (CDT-BTZ) donor-acceptor copolymer film whose chain direction is oriented by mechanical compression at the surface of an ionic liquid. The mobility is 5.6 cm(2) V(-1) s(-1) at room temperature, and is further improved to 6.7 cm(2) V(-1) s(-1) at 260 K.

Abstract
SETTING Although standardised multidrug treatments exist, mortality among hospitalised tuberculosis (TB) patients is high. OBJECTIVE To characterise TB patients requiring acute hospital care and identify factors associated with in-hospital mortality. DESIGN Using a Japanese national database of acute-care hospitals, we identified patients with sputum smear-positive pulmonary TB who were discharged (both deceased and alive) between July 2010 and March 2013. Demographic characteristics, comorbidity, procedures and treatments were examined. We performed a multivariable logistic regression analysis to identify risk factors for in-hospital mortality. RESULTS Of 877 treated patients (566 males, mean age 74.5 years) identified, 152 (17.3%) died. A standard four-drug regimen of isoniazid (INH), rifampicin (RMP), ethambutol (EMB) and pyrazinamide was given to 279 (31.8%) patients, and INH, RMP and EMB to 335 (38.2%) patients. Multivariable analysis showed that the three-drug regimen was significantly associated with higher rates of in-hospital mortality (OR 1.87, 95%CI 1.07-3.27, P = 0.028). Other factors associated with in-hospital death were age, male sex, smoking habit, emergency admission, dementia and severe respiratory condition. CONCLUSION The risk factors for in-hospital death identified include the use of the three-drug regimen. Treatment choice could influence the outcome of hospitalised TB patients.

Abstract
Mutations in ASXL1 are frequent in patients with myelodysplastic syndrome (MDS) and associated with adverse survival yet the molecular pathogenesis of ASXL1 mutations are not fully understood. Recently it has been found that deletion of Asxl1 or expression of C-terminal-truncating ASXL1 mutations (ASXL1-MT) inhibit myeloid differentiation and induce MDS-like disease in mice. Here, we find that SETBP1 mutations (SETBP1-MT) are enriched among patients with ASXL1-mutated MDS patients and associated with increased incidence of leukemic transformation as well as shorter survival, suggesting SETBP1-MT play a critical role in leukemic transformation of MDS. We identify that SETBP1-MT inhibit ubiquitination and subsequent degradation of SETBP1, resulting in increased expression. Expression of SETBP1-MT, in turn, inhibited Pp2a activity, leading to Akt activation and enhanced expression of posterior Hoxa genes in ASXL1 mutant cells. Biologically, SETBP1-MT augmented ASXL1-MT-induced differentiation block, inhibited apoptosis, and enhanced myeloid colony output. SETBP1-MT collaborated with ASXL1-MT in inducing AML in vivo. The combination of ASXL1-MT and SETBP1-MT activated a stem cell signature and repressed the TGF-β signaling pathway, in contrast to the ASXL1-MT-induced MDS model. These data reveal that SETBP1-MT are critical drivers of ASXL1-mutated MDS and identify several deregulated pathways as potential therapeutic targets in high-risk MDS.

Abstract
A novel and versatile method to align polymer semiconductors is demonstrated. Spreading and subsequent mechanical compression of a polymer thin film on an ionic liquid's surface yield a polymer thin film that has high uniaxial orientation of the polymer backbone, which is tested for typical polymer semiconductors of PB16TTT, PNDTBTC20, and P3HT. TFTs fabricated by the method exhibit significantly higher mobility compared to TFTs fabricated using a conventional spin-coating process.

Abstract
BACKGROUND The association between antithrombin use and mortality in patients with sepsis-associated disseminated intravascular coagulation (DIC) remains controversial. OBJECTIVES To examine the hypothesis that antithrombin could be effective in the treatment of patients with sepsis-associated DIC following severe pneumonia. METHODS Propensity score and instrumental variable analyses were performed by use of a nationwide administrative database, the Japanese Diagnosis Procedure Combination inpatient database. The main outcome was 28-day mortality. RESULTS Severe pneumonia patients diagnosed with sepsis-associated DIC (n = 9075) were categorized into antithrombin (n = 2663) and control (n = 6412) groups. Propensity score matching created a matched cohort of 2194 pairs of patients with and without antithrombin use. Mortality differences were found between the two groups (antithrombin vs. control: unmatched, 40.8% vs. 45.7%; propensity-matched, 40.6% vs. 44.2%; inverse probability-weighted, 41.1% vs. 45.1%). Multiple logistic regression analyses showed an association between antithrombin use and 28-day mortality (unmatched with propensity score adjusted, adjusted odds ratio [OR] 0.87, 95% confidence interval [CI] 0.78-0.97; propensity-matched, adjusted OR 0.85, 95% CI 0.75-0.97; inverse probability-weighted, adjusted OR 0.85, 95% CI 0.79-0.90). An analysis with the hospital antithrombin-prescribing rate as an instrumental variable showed that receipt of antithrombin was associated with a 9.9% (95% CI 3.5-16.3) reduction in 28-day mortality. CONCLUSIONS This retrospective, large, nationwide database study demonstrates that antithrombin administration may be associated with reduced 28-day mortality in patients with severe pneumonia and sepsis-associated DIC. A large, multinational randomized trial is required.
