ABSTRACT
@#Objective To compare the clinical outcomes of transcatheter aortic valve implantation (TAVI) in oncology and non-oncology patients with severe aortic stenosis (AS). Methods A computer-based search in PubMed, The Cochrane Library, EMbase, CBM, CNKI and Wanfang databases from their date of inception to December 2021 was performed, together with reference screening, to identify eligible clinical trials. Two investigators screened the articles, extracted data, and evaluated quality independently. RevMan 5.3 and Stata 12.0 softwares were used for meta-analysis. Results The selected 8 cohort studies contained 57 988 patients, including 12 335 cancer patients and 45 653 non-cancer patients. The results of meta-analysis showed that in patients with cancer, the 30-day mortality [OR=0.74, 95%CI (0.65, 0.84), I2=0%, P<0.000 01], stroke [OR=0.87, 95%CI (0.76, 0.99), I2=0%, P=0.04] and acute kidney injury [OR=0.81, 95%CI (0.76, 0.85), I2=49%, P<0.000 01] were lower than those in patients without cancer. The 1-year mortality [OR=1.46, 95%CI (1.15, 1.86), I2=62%, P=0.002] and late mortality [OR=1.51, 95%CI (1.24, 1.85), I2=61%, P<0.000 1] were higher in patients with cancer. Conclusion It is effective and safe in cancer patients with severe AS undergoing TAVI. However, compared with patients without cancer, it is still high in long-term mortality, and further study of the role of TAVI in cancer patients with AS is necessary.
ABSTRACT
Background@#Bovine papilloma is a neoplastic disease caused by bovine papillomaviruses (BPVs), which were recently divided into 5 genera and at least 24 genotypes. @*Objectives@#The complete genome sequence of BPV type 15 (BPV Aks-02), a novel putative BPV type from skin samples from infected cows in Southern Xinjiang China, was determined by collecting warty lesions, followed by DNA extraction and amplicon sequencing. @*Methods@#DNA was analyzed initially by polymerase chain reaction (PCR) using the degenerate primers FAP59 and FAP64. The complete genome sequences of the BPV Aks-02 were amplified by PCR using the amplification primers and sequencing primers. Sequence analysis and phylogenetic analysis were performed using bio-informatic software. @*Results@#The nucleotide sequence of the L1 open reading frame (ORF) of BPV Aks-02 was 75% identity to the L1 ORF of BPV-9 reference strain from GenBank. The complete genome consisted of 7,189 base pairs (G + C content of 42.50%) that encoded 5 early (E8, E7, E1, E2, and E4) and 2 late (L1 and L2) genes. The E7 protein contained a consensus CX2CX29CX 2 C zinc-binding domain and a LxCxE motif. Among the different members of this group, the percentages of the complete genome and ORFs (including 5 early and 2 late ORFs) sequence identity of BPV Aks-02 were closer to the genus Xipapillomavirus 1 of the Xipapillomavirus genus.Phylogenetic analysis and sequence similarities based on the L1 ORF of BPV Aks-02 revealed the same cluster. @*Conclusions@#The results suggest that BPV type (BPV Aks-02) clustered with members of the Xipapillomavirus genus as BPV 15 and were closely related to Xipapillomavirus 1.
