| 5 | Prevalence and prognostic value of cardiac troponin in elderly patients hospitalized for COVID-19显示文摘BACKGROUND Increases in cardiac troponin(cTn)in coronavirus disease 2019(COVID19)have been associated with worse prognosis.Nonetheless,data about the significance of cTn in elderly subjects with COVID19 are lacking.METHODS From a registry of consecutive patients with COVID19 admitted to a hub hospital in Italy from 25/02/2020 to 03/07/2020,we selected those≥60 yearold and with cTnI measured within three days from the molecular diagnosis of SARSCoV2 infection.When available,a second cTnI value within 48 h was also extracted.The relationship between increased cTnI and allcause inhospital mortality was evaluated by a Cox regression model and restricted cubic spline functions with three knots.RESULTS Of 343 included patients(median age:75.0(68.0−83.0)years,34.7%men),88(25.7%)had cTnI above the upperreference limit(0.046μg/L).Patients with increased cTnI had more comorbidities,greater impaired respiratory exchange and higher inflammatory markers on admission than those with normal cTnI.Furthermore,they died more(73.9%vs.37.3%,P<0.001)over 15(6−25)days of hospitalization.The association of elevated cTnI with mortality was confirmed by the adjusted Cox regression model(HR=1.61,95%CI:1.06−2.52,P=0.039)and was linear until 0.3μg/L,with a subsequent plateau.Of 191(55.7%)patients with a second cTnI measurement,49(25.7%)had an increasing trend,which was not associated with mortality(univariate HR=1.39,95%CI:0.87−2.22,P=0.265).CONCLUSIONS In elderly COVID19 patients,an initial increase in cTn is common and predicts a higher risk of death.Serial cTn testing may not confer additional prognostic information. | Vincenzo De Marzo Antonio Di Biagio Roberta Della Bona Antonio Vena Eleonora Arboscello Harusha Emirjona Sara Mora Mauro Giacomini Giorgio Da Rin Paolo Pelosi Matteo Bassetti Pietro Ameri Italo Porto GECOVID study group | 2021 | Journal of Geriatric Cardiology2021，18，5： | 0 |
| 6 | Structure,stability,catalytic activity,and polarizabilities of small iridium clusters显示文摘At the second order Douglas–Kroll–Hess(DKH2) level, the B3 PW91 functional in conjunction with the relativistic all-electron basis set of valence triple zeta quality plus polarization functions are employed to compute bond lengths, dissociation energies, vertical ionization potentials, and the highest occupied molecular orbital-lowest unoccupied molecular orbital energy gaps of the small iridium clusters(Ir_n, n≤8). These results are compared with the experimental and theoretical data available in the literature. Our results confirm the theoretical predictions made by Feng et al. about the catalytic activities of the Ir_4 and Ir_6 clusters. From the optimized geometries, DKH2 calculations of static electric mean dipole polarizabilities and polarizability anisotropies are also carried out. It is the first time that the polarizabilities of small iridium clusters have been studied. For n≤4, the mean dipole polarizabilities per atom present an odd–even oscillatory behavior,whereas from Ir_5 to Ir_8, they decrease with the cluster size increasing. The dependence of the polarizability anisotropy on the structure symmetry of the iridium cluster is verified. | Francisco E Jorge JoséR da Costa Venaâncio | 2018 | Chinese Physics B2018，27，6： | 0 |
