To compare the rate of pregnancy complicated with premature rupture of membranes (PROM) and obstetric outcomes of twin pregnancies and singleton pregnancies. A retrospective cohort study was conducted on twin and singleton pregnancies that delivered at Rajavithi Hospital, Tertiary public hospital, Bangkok, Thailand between January 1, 2008 and July 31, 2012. Singleton pregnancies as a control group were matched with twin pregnancies based on date ofdelivery, with a ratio of]:1. The main outcome of measure was the prevalence ofpreterm rupture of membranes. The prevalence of PROM among twin pregnancies had a tendency to be lower than that in singleton pregnancies, 5.4% vs. 9%, but the difference was not statistically significant (p = 0.053). The mean gestational age at delivery for twin pregnancies was significantly lower than singleton, 34.8±3.1 weeks vs. 38.1±2.1 weeks (p<0.001). The rates of cesarean delivery, low birth weight baby, and APGAR scores less than 7at 5 minutes were also significantly higher in twin pregnancies. The prevalence of PROM in twin pregnancies had a tendency to be lower than that in singleton, but not statistically significant. The reason may be associated with a high rate ofpre-labor cesarean section due...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.
