Prediction of major complications after hepatectomy using liver stiffness values determined by magnetic resonance elastography. Br J Surg 2018; 105:1192-1199.

Abstract
BACKGROUND Liver fibrosis is a risk factor for hepatectomy but cannot be determined accurately before hepatectomy because diagnostic procedures are too invasive. Magnetic resonance elastography (MRE) can determine liver stiffness (LS), a surrogate marker for assessing liver fibrosis, non-invasively. The aim of this study was to investigate whether the LS value determined by MRE is predictive of major complications after hepatectomy. METHODS This prospective study enrolled consecutive patients who underwent hepatic resection between April 2013 and August 2016. LS values were measured by imaging shear waves by MRE in the liver before hepatectomy. The primary endpoint was major complications, defined as Clavien-Dindo grade IIIa or above. Logistic regression analysis identified independent predictive factors, from which a logistic model to estimate the probability of major complications was constructed. RESULTS A total of 96 patients were included in the study. Major complications were observed in 15 patients (16 per cent). Multivariable logistic analysis confirmed that higher LS value (P = 0·021) and serum albumin level (P = 0·009) were independent predictive factors for major complications after hepatectomy. Receiver operating characteristic (ROC) analysis showed that the best LS cut-off value was 4·3 kPa for detecting major complications, comparable to liver fibrosis grade F4, with a sensitivity of 80 per cent and specificity of 82 per cent. A logistic model using the LS value and serum albumin level to estimate the probability of major complications was constructed; the area under the ROC curve for predicting major complications was 0·84. CONCLUSION The LS value determined by MRE in patients undergoing hepatectomy was an independent predictive factor for major complications.

Abstract
We present the development of a frequency-domain multiplexing readout of kinetic inductance detectors (KIDs) for pulse signals with a self-trigger system. The KIDs consist of an array of superconducting resonators that have different resonant frequencies individually, allowing us to read out multiple channels in the frequency domain with a single wire using a microwave-frequency comb. The energy deposited to the resonators break Cooper pairs, changing the kinetic inductance and, hence, the amplitude and the phase of the probing microwaves. For some applications such as X-ray detections, the deposited energy is detected as a pulse signal shaped by the time constants of the quasiparticle lifetime, the resonator quality factor, and the ballistic phonon lifetime in the substrate, ranging from microseconds to milliseconds. A readout system commonly used converts the frequency-domain data to the time-domain data. For the short pulse signals, the data rate may exceed the data transfer bandwidth, as the short time constant pulses require us to have a high sampling rate. In order to overcome this circumstance, we have developed a KID readout system that contains a self-trigger system to extract relevant signal data and reduces the total data rate with a commercial off-the-shelf FPGA board. We have demonstrated that the system can read out pulse signals of 15 resonators simultaneously with about 10 Hz event rate by irradiating α particles from 241 Am to the silicon substrate on whose surface aluminum KID resonators are formed.

Abstract
We report on the first global QCD analysis of the quark transversity distributions in the nucleon from semi-inclusive deep-inelastic scattering (SIDIS), using a new Monte Carlo method based on nested sampling and constraints on the isovector tensor charge g_{T} from lattice QCD. A simultaneous fit to the available SIDIS Collins asymmetry data is compatible with g_{T} values extracted from a comprehensive reanalysis of existing lattice simulations, in contrast to previous analyses, which found significantly smaller g_{T} values. The contributions to the nucleon tensor charge from u and d quarks are found to be δu=0.3(2) and δd=-0.7(2) at a scale Q^{2}=2 GeV^{2}.

Abstract
A sympathetic neurogram is potentially useful for the development of a real time total artificial heart (TAH) control system. We used sympathetic tone and hemodynamic derivatives to estimate the following cardiac output in acute animal experiments using adult mongrel dogs. Moving averages of the mean left atrial pressure and mean aortic pressure were used as parameters of the preload and afterload, respectively. Renal sympathetic nerve activity (RSNA) was employed as a parameter of sympathetic tone. Equations for the following cardiac output were calculated using multiple linear regression analysis of the time series data. A significant correlation was observed between the estimated and following measured cardiac output. These results suggest the potential usefulness of the sympathetic neurogram for the real time TAH automatic control system.

Abstract
To assess the effect of a total artificial heart (TAH) on the autonomic nervous system a power spectral analysis of the hemodynamics in a TAH animal was done by the maximum entropy method. Two pneumatically driven sac-type ventricular assist devices were implanted as total biventricular bypass (BVB) in adult mongrel dogs to compare the differences between natural heart and TAH. Once the BVB was pumping, the natural heart was electrically fibrillated to constitute the BVB-type TAH model. In the arterial pressure waveform in animals with TAH, respiratory waves were not changed (97.7±24.6%) though Mayer waves were significantly decreased (47.5 ± 22.6%) compared with the animal with a natural heart. These results suggest that prosthetic hemodynamics in the TAH animal affect fluctuations in the cardiovascular system.

Abstract
Abstract
Aims We investigated the efficacy and safety of initial neoadjuvant endocrine therapy with exemestane (EXE) alone followed by subsequent tailored treatment with EXE alone for responders or EXE plus oral metronomic cyclophosphamide (CPA) for non-responders.
Methods In this multicenter open-label phase II study, we enrolled postmenopausal patients with primary invasive estrogen receptor (ER)-positive, HER2-negative, stage I–IIIA (T1c–T3 N0–2 M0) breast cancer and Ki67 index ≤ 30%. Patients first received EXE 25mg/day for 12 weeks. Based on clinical response and change in Ki67 index in response to the initial therapy, patients who achieved complete response (CR), partial response (PR) with Ki67 index ≤5% after treatment, or stable disease (SD) with Ki67 index ≤5% both before and after treatment were defined as responders. Non-responders were defined as patients with PR and Ki67 index >5% after treatment, or SD and Ki67 index >5% before or after treatment. For the subsequent 24 weeks, responders continued the EXE monotherapy (continued EXE group), whereas non-responders switched to combination therapy with EXE plus CPA 50mg/day (EXE+CPA group). The primary endpoint was clinical response (CR and PR) at weeks 24 and 36.
Results A total of 59 patients (median age 69 years, range 53–86 years) were enrolled between January 2011 and July 2015. After exclusion of 3 (2 with progressive disease, 1 with an adverse event, AE) who discontinued treatment in the initial 12-week EXE monotherapy period, 56 remained enrolled to receive subsequent treatment. After 8–12 weeks of the initial EXE monotherapy, 14 patients were classified as responders (9 with PR and Ki67 index ≤5% after treatment; 5 with SD and Ki67 index ≤5% before and after treatment), whereas 42 were classified as non-responders (3 with PR and Ki67 index >5% after treatment; 39 with SD and Ki67 index >5% before or after treatment). Clinical response rates at weeks 24 and 36 were 85% (12/14, 95%CI 57.2–98.2%) and 76% (10/13, 95%CI 46.2–95.0%), respectively, in the continued EXE group, and 56% (23/41, 95%CI 39.7–71.5%) and 76% (30/39, 95%CI 60.7–88.9%), respectively, in the EXE+CPA group. At week 36, no significant difference was found in median Ki67 index between the continued EXE and EXE+CPA groups (3.5% and 4.0%, respectively). The proportion of patients with preoperative endocrine prognostic index (PEPI) 0 was also similar between the continued EXE and EXE+CPA groups (21.4% and 23.8%, respectively). The breast-conserving surgery rate was 71.4% and 69.0%, respectively. Grade 3 AEs were elevated liver enzymes (1 patient) in the continued EXE group, and gastritis, hypertriglyceridemia, and bone mineral density loss (1 patient each) in the EXE+CPA group.
Conclusion Switching from EXE monotherapy to EXE+CPA combination therapy based on clinical response and biological response (change in Ki67 index) to initial therapy improved subsequent clinical response in non-responders. Favorable clinical response to EXE alone was maintained in responders. Tailored neoadjuvant endocrine and chemo-endocrine therapy was shown to be effective in postmenopausal ER-positive breast cancer patients. (JBCRG-11CPA; UMIN000004751)

Abstract
Topological constraints on a dynamical system often manifest themselves as breaking of the Hamiltonian structure; well-known examples are nonholonomic constraints on Lagrangian mechanics. The statistical mechanics under such topological constraints is the subject of this study. Conventional arguments based on phase spaces, Jacobi identity, invariant measure, or the H theorem are no longer applicable since all these notions stem from the symplectic geometry underlying canonical Hamiltonian systems. Remembering that Hamiltonian systems are endowed with field tensors (canonical 2-forms) that have zero helicity, our mission is to extend the scope toward the class of systems governed by finite-helicity field tensors. Here, we introduce a class of field tensors that are characterized by Beltrami vectors. We prove an H theorem for this Beltrami class. The most general class of energy-conserving systems are non-Beltrami, for which we identify the "field charge" that prevents the entropy to maximize, resulting in creation of heterogeneous distributions. The essence of the theory can be delineated by classifying three-dimensional dynamics. We then generalize to arbitrary (finite) dimensions.

Abstract
Summary
Objectives
: Our objective is to investigate diabetes- related alteration of glucose control in diurnal fluctuations in normal daily life by detrended fluctuation analysis (DFA).
Methods
: The fluctuations of glucose of 12 non-diabetic subjects and 15 diabetic patients were measured using a continuous glucose monitoring system (CGMS) over a period of one day. The glucose data was calculated by the DFA method, which is capable of revealing the presence of long-range correlations in time series with inherent non-stationarity.
Results
: Compared with the non-diabetic subjects, the mean glucose level and the standard deviation are significantly higher in the diabetic group.The DFA exponent α is calculated, and glucose time series are searched for the presence of negatively (0.5 < α <1.5) or positively (1.5 < α) correlated fluctuations. A crossover phenomenon, i.e. a change in the level of correlations, is observed in the non-diabetic subjects at about two hours; the net effects of glucose flux/reflux causing temporal changes in glucose concentration are negatively correlated in a “long-range" (> two hours) regime. However, for diabetic patients, the DFA exponent α = 1.65 ± 0.30, and in the same regime positively correlated fluctuations are observed, suggesting that the net effects of the flux and reflux persist for many hours.
Conclusions
: Such long-range positive correlation in glucose homeostasis may reflect pathogenic mechanisms of diabetes, i.e., the lack of the tight control in blood glucose regulation. Using modern time series analysis methods such as DFA, continuous evaluation of glucose dynamics could promote better diagnoses and prognoses of diabetes and a better understanding of the fundamental mechanism of glucose dysregulation in diabetes.

Abstract
SummaryIschemic stroke (IS) is thought to be a multifactorial disorder associated with genetic backgrounds and environmental factors. In the circulating plasma, tissue plasminogen activator (tPA) catalyzes the reaction from plasminogen to plasmin. If there is a functional disability of tPA, induction of thrombosis and infarction disorders can occur. The aim of this study was to performa haplotype-based case-control study using single nucleotide polymorphisms (SNPs) in the human tPA gene, and to assess the association between the tPA gene and IS. We genotyped 182 IS individuals and 403 controls for five SNPs in the human tPA gene, rs7007329, rs732612, rs8178750, rs2020922, and rs4471024. Using these five SNPs, a haplotype-based case control study was performed. There were seven SNP combinations that exhibited significant differences in the overall distribution between the IS and control groups. Linkage disequilibrium analysis showed that the combination of rs7007329 and rs8178750 was useful in identification of the susceptibility haplotype. The frequency of the G-T haplotype at rs7007329-rs8178750 was significantly higher in the IS group (1.2%) as compared to the control group (0.0%) (p=0.003).Diplotype analysis also showeda significant association of the diplotype with the G-T haplotype at rs7007329-rs8178750 (OR:11.4, 95%CI:1.32–97.9, p=0.013). These results suggest that the G-T haplotype at rs7007329-rs8178750 of the tPA gene isa genetic marker for IS, and that tPA ora neighboring gene isa susceptibility gene for IS.

Abstract
Neuronal intranuclear inclusion disease is a neurodegenerative disorder pathologically characterized by eosinophilic hyaline intranuclear inclusions. A high-intensity signal along the corticomedullary junction on DWI has been described as a specific MR imaging finding of the cerebrum in neuronal intranuclear inclusion disease. However, MR imaging findings of the cerebellum in neuronal intranuclear inclusion disease have not been fully evaluated. Here, we review MR imaging findings of the cerebellum in a series of 8 patients with pathologically confirmed neuronal intranuclear inclusion disease. The MR imaging results showed cerebellar atrophy (8/8 patients) and high-intensity signal on FLAIR images in the medial part of the cerebellar hemisphere right beside the vermis (the "paravermal area") (6/8) and in the middle cerebellar peduncle (4/8). The paravermal abnormal signals had a characteristic distribution, and they could be an indicator of the diagnosis of neuronal intranuclear inclusion disease even when using the results of past MR imaging examinations in which DWI findings were not examined.

Abstract
To determine whether maximum bite force (MBF), an objective measure of oral function, is associated with development of frailty in community-dwelling older adults. This prospective cohort study included community-dwelling Japanese adults aged 75 years at baseline (n = 322). Baseline MBF was measured using an electronic recording device (Occlusal Force-Meter GM10). Follow-up examinations, including physical fitness and anthropometric evaluation and structured questionnaires, were administered annually over a 5-year period to determine the incidence of frailty, which was defined by the presence of 3 or more of the following 5 components derived from the Cardiovascular Health Study: low level of mobility, low physical activity level, weakness, shrinking and poor endurance and energy. Adjusted hazard ratios (HRs) of incidence of frailty according to sex-stratified tertiles of baseline MBF were calculated using Cox proportional hazards regression models. During the follow-up, 49 participants (15.2%) developed frailty. Participants in the lower tertile of MBF exhibited a significantly greater risk of frailty than those in the upper tertile. After adjustment for sex, depression, diabetes and Eichner index, the adjusted HRs for frailty in the upper through lower tertiles of MBF were 1.00 (reference), 1.27 (95% confidence interval [CI]: 0.50-3.20) and 2.78 (95% CI: 1.15-6.72), respectively (P for trend = .01). Poor oral function, as indicated by low MBF, increases the risk of development of frailty among elderly men and women.
