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(≥18 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 13 included studies showed a significant association of frailty with elevated risk of in-hospital mortality(RR=2.76,95%CI:2.10-3.64),mortality at 30 d(RR=4.60,95%CI:1.85-11.40),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.

Development of a Synthetic Peptide ELISA Assay for the Detection of Foot-and-Mouth Disease Virus Nonstructural Protein Antibodies

引用

Agricultural Sciences in China 2010年第11期9卷 1677-1683页

作者： YANG Ji-fei YANG Su-zhen YANG Yan-yan ZHI Ai-min ZHAO Dong ZHI Yu-bao xing guang-xu DENG Rui-guang CHAI Shu-jun ZHANG Gai-ping Henan Provincial Key Laboratory for Animal Immunology Henan Academy of Agricultural Sciences Zhengzhou 450002 P.R.China College of Veterinary Medicine Henan Agricultural University Zhengzhou 450002 P.R.China

In order to develop an ELISA assay with synthetic peptides for the detection of antibody to the nonstructural proteins of foot-and-mouth disease virus, specific peptides were synthesized by a solid-phase method according to FMDV NSPs B-cell epitopes, and were conjugated to carrier protein BSA. An ELISA system was developed to detect FMDV NSPs antibody with the conjugated proteins as the coating antigen. The optimal coating concentration of the antigen was determined as 2.5 μg mL-1. The comparative study of this assay with UBI NSP ELISA kit and national commercial 3ABC ELISA kit in the detection of 199 serum samples showed that they were very coincident, and the identity rates were 96.48 and 97.48%, respectively. The development of ELISA using the synthetic peptides as coating antigen is specific, reproducible, stable, and easy, and can be used to differentiate FMDV infected pigs from immunized pigs.
