BACKGROUND The impact of frailty on postoperative outcomes in patients undergoing hepatectomy is still *** To study the influence of frailty on postoperative outcomes,such as mortality,rate of complications,and length of hospitalization,following *** PubMed,EMBASE,and Scopus databases were searched for observational studies with adult(≥1. years)patients after planned/elective hepatectomy.A randomeffects model was used for all analyses,and the results are expressed as weighted mean difference(WMD),relative risk(RR),or hazards ratio(HR)with 95%confidence interval(CI).RESULTS Analysis of the 1. included studies showed a significant association of frailty with elevated risk of in-hospital mortality(RR=2.76,95%CI:2.1.-3.64),mortality at 30 d(RR=4.60,95%CI:1.85-1..40),and mortality at 90 d(RR=2.52,95%CI:1.70-3.75)in the postoperative *** patients had a poorer long-term survival(HR=2.89,95%CI:1.84-4.53)and higher incidence of“any”complications(RR=1.69,95%CI:1.40-2.03)and major(grade III or higher on the Clavien-Dindo scale)complications(RR=2.69,95%CI:1.85-3.92).Frailty was correlated with markedly lengthier hospital stay(WMD=3.65,95%CI:1.45-5.85).CONCLUSION Frailty correlates with elevated risks of mortality,complications,and prolonged hospitalization,which need to be considered in surgical *** research is essential to formulate strategies for improved outcomes in this vulnerable cohort.

Simultaneous Bulk-and Surface-initiated Living Polymerization Studied with a Heterogeneous Stochastic Reaction Model

引用

Chinese Journal of Polymer Science 2024年第3期42卷 364-372,I0008页

作者： jia-Shu Ma Zhi-Ning Huang jia-Hao Li Bang-Ping jiang Yan-Da Liao Shi-Chen Ji Xing-Can Shen State Key Laboratory for Chemistry and Molecular Engineering of Medicinal Resources Key Laboratory for Chemistry and Molecular Engineering of Medicinal Resources(Ministry of Education of China)School of Chemistry and Pharmaceutical SciencesGuangxi Normal UniversityGuilin 541004China School of Computer Science and Engineering&School of Software Guangxi Normal UniversityGuilin 541004China

To better characterize the properties of surface-initiated polymers, simultaneous bulk-and surface-initiated polymerizations are usually carried out by assuming that the properties of the surface-initiated polymers resemble those of the bulk-initiated polymers. Through a Monte Carlo simulation using a heterogeneous stochastic reaction model, it was discovered that the bulk-initiated polymers exhibit a higher molecular weight and a lower dispersity than the corresponding surface-initiated polymers, which indicates that the equivalent assumption is invalid. Furthermore, the molecular weight distributions of the two types of polymers are also different, suggesting different polymerization mechanisms. The results can be simply explained by the heterogeneous distributions of reactants in the system. This study is helpful to better understand surface-initiated polymerization.
