OBJECTIVE To estimate the prevalence of preterm birth by categories of birth weight, and to obtain an equation to correct the estimates. METHODS Systematic review of the Brazilian literature published from 1990 to 2012, to identify studies with primary collection of data on birth weight and gestational age. Twelve studies were selected and contributed for tabulations of preterm prevalence acc...
The aim of the present study was to analyze the live weight, body length, and chest perimeter in Blackhead Pleven lambs at an early age with a view to their future use as prognostic indicators of growth performance. The study was conducted with 46 lambs. It found out that at birth and weaning the singletons had higher live weight and higher average daily weight gain in comparison with the twins (P
OBJECTIVE To compare the effectiveness of elective single embryo transfer versus double embryo transfer on the outcomes of live birth, multiple live birth, miscarriage, preterm birth, term singleton birth, and low birth weight after fresh embryo transfer, and on the outcomes of cumulative live birth and multiple live birth after fresh and frozen embryo transfers. DESIGN One stage meta-analysi...
Live birth has evolved many times independently in vertebrates, such as mammals and diverse groups of lizards and snakes. However, live birth is unknown in the major clade Archosauromorpha, a group that first evolved some 260 million years ago and is represented today by birds and crocodilians. Here we report the discovery of a pregnant long-necked marine reptile (Dinocephalosaurus) from the Mi...
