Novel Swine-Origin Influenza A Virus Investigation Team: Emergence of a Novel Swine-Origin Influenza A Virus in Humans Triple-reassortant swine influenza viruses, which contain genes from human, swine, and avian influenza A viruses, have been recognized in swine in the usa since 1998,1,2 and 12 cases of individual infection with such viruses had been determined in the United States from 2005 through 2009 Diprolene.eu .3 On April 15 and April 17, 2009, the Centers for Disease Control and Prevention identified two cases of human infections with a swine-origin influenza A virus characterized by a unique mix of gene segments that was not identified among individual or swine influenza A infections.

Gammill, M.D.: Short Report: Copy-Quantity Variation and False Positive Prenatal Aneuploidy Screening Results Methods of noninvasive prenatal screening1 have advanced in clinical practice rapidly, with aneuploidy screening predicated on analysis of circulating cfDNA routinely offered to females with high-risk pregnancies now. Owing to the high reported precision of the screening tests,2,3 attention has shifted to low-risk cohorts, where the reduced incidence of aneuploidy may limit the positive predictive value of noninvasive prenatal screening.4 A recent prospective analysis of cfDNA-based noninvasive prenatal screening in 1914 low-risk pregnancies showed false positive rates of 0.3 percent, 0.2 percent, and 0.5 However, the positive predictive value was 45.5 percent for trisomy 21 and 40.0 percent for trisomy 18,5 highlighting the necessity for follow-up diagnostic screening.
