In this region, the last outbreaks of the disease occurred in 1998, while in the NFZ, 28 outbreaks were detected from 2005 to 2017, with an apparent lethality rate of 93.96% (840/894). However, in 2018 and 2019, 68 new outbreaks were registered with an apparent lethality rate of 75.05% (1095/1459). Therefore, in 2019, the Brazil CSF-Free Strategic…[Read more]

Results showed that MMP2 (-735C>T) presented a statistically significant association with the risk of RSA under allelic (T vs C OR=1.50, 95% CI=1.14-1.98, P=0.004, I

=31%), heterozygote (CT vs CC OR=1.74, 95% CI=1.22-2.50, P=0.003, I

=41%) and dominant (TT+CT vs CC OR=1.74, 95% CI=1.23-2.45, P=0.002, I

=40%) genetic models. MMP9…[Read more]
