| 1 | Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis. | Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg | 2017 | World Journal of Hepatology2017，9，7： | 11 |
| 2 | Thermodynamic functions of ZrW_2O_8 from its heat capacity显示文摘It is interesting to maximize the amount of information we can obtain from one experiment on a single sample.In obtaining all the thermodynamic properties of some materials from their experimental heat capacity data only,we aim to get the temperature-independent energy spectrum.However,all the practical measured energy spectra depend on the temperature of experiments.One promising method to obtain the temperature-independent energy spectrum is to solve the so-called specific heat-phonon spectrum inversion(SPI) problem.Here we show,by developing a new practical solution method of SPI,the phonon spectrum of the negative thermal expansion material ZrW 2 O 8 is obtained.This phonon spectrum is temperature-independent and almost method independent.Hence all the thermodynamic properties of ZrW 2 O 8,such as thermodynamic potential,entropy,Helmholtz free energy,etc.are obtained by heat capacity only. | Ji FengMin DAI XianXi STEVENS R GOATES J B | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，4： | 3 |
