Correlations between the COMT gene rs4680 polymorphism and susceptibility to ovarian cancer

W. Pan and Liao, H., Correlations between the COMT gene rs4680 polymorphism and susceptibility to ovarian cancer, vol. 14, pp. 16813-16818, 2015.

The objective of this study was to perform a systematic review of the correlations between the single nucleotide polymorphism rs4680 in the catechol-O-methyltransferase (COMT) gene and susceptibility to ovarian cancer. A computer search was carried out for relevant case-control studies published between January 2000 to January 2014 in databases such as Ovid, EBSCO, PubMed, CNKI, CBMDISC, VIP, and WanFang Data. The literature was screened based on inclusion and exclusion criteria.

Systematic review of noninvasive prenatal diagnosis for abnormal chromosome genetic diseases using free fetal DNA in maternal plasma

H. Yang, Xu, H. B., Liu, T. T., and He, X. L., Systematic review of noninvasive prenatal diagnosis for abnormal chromosome genetic diseases using free fetal DNA in maternal plasma, vol. 14, pp. 10603-10608, 2015.

We evaluated the system accuracy of noninvasive prenatal diagnosis for abnormal chromosome genetic diseases using cell-free fetal DNA in maternal plasma. Previous studies were searched in the MEDLINE database using the following keywords: “prenatal” and “aneuploidy” and “noninvasive or non-invasive” and “maternal”. Identified studies were filtered using a QUADAS instrument. Four studies were identified and analyzed using QUADAS.
