BACKGROUND: Low birth weight (<2,500 g) is a strong predictor of infant mortality. Yet low birth weight, in isolation, is uninformative since it is comprised of two intertwined components: preterm delivery and reduced fetal growth. Through nonparametric logistic regression models, we examine the effects of gestational age, fetal growth, and maternal smoking on neonatal mortality. METHODS: We de...

OBJECTIVE To evaluate Michigan newborn screening for congenital hypothyroidism (CH) protocol changes. METHODS This population-based study includes infants born and screened in Michigan (January 1, 1994-June 30, 2010). Screening performance is compared across 4 periods defined by the dried blood spot testing method: (1) thyroxine (T4) with backup thyrotropin, (2) tandem T4 and thyrotropin, (3)...

Much of the decline in childhood mortality over the past two decades is attributable to improvements in neonatal intensive care for very-low-birthweight infants. Yet large and persistent disparities persist in the quality of neonatal intensive care across hospitals. Improving care for infants now served by hospitals with poor outcomes can greatly reduce infant mortality, particularly among mino...

BACKGROUND The possible interference of assisted reproduction techniques (ART) with epigenetic reprogramming during early embryo development has recently sparked renewed interest about the reported lower birth weight among infants born as a consequence of infertility treatments. However, the latter finding so far has relied on the comparison of the birth weight of infants conceived with ART to ...

Background: Comparison of obstetric and neonatal outcomes of twin pregnancies conceived by assisted reproduction technology (ART) with those of spontaneously conceived (SC). Materials and Methods: In this prospective cohort study, all dichorionic twin pregnancies following fresh IVF/ intra-cytoplasmic sperm injection (ICSI) or ICSI cycles (n=320) and (SC) (n=170) in nulliparous women in Royan I...

introduction minerals and trace elements such as zinc and copper have significant influence on development and growth of the fetus and newborn. the purpose of this study was to determine the relationship between low birth weight and maternal and neonatal zinc, copper levels. materials and methods this case – control study   was done from september 2006 to sep 2007 consisted of 65 infants with b...

BACKGROUND Birth weight mortality statistics are important for examining trends and monitoring the outcomes of neonatal care. AIM To determine the effects of errors in the registered birth weight on birth weight specific mortality. METHODS All twins born in England and Wales during 1993-95 comprise the denominator population. For those twins that died, the Office for National Statistics (ON...

INTRODUCTION Neonatal mortality (NM) refers to deaths occurring between birth and 27 days of life. This component of infant mortality has shown the least reduction over the past 50 years. The objective of this study was to analyze the course and characteristics of NM in Argentina. POPULATION AND METHODS This was a descriptive, ecological study of NM in Argentina conducted between 2005 and 201...

conclusions no significant differences were observed between the groups based on the neonatal outcome including neonatal anthropometric parameters and lack of congenital anomaly. results there was no difference between the groups in the mean age of mother and the mean age of gestation. no differences were found between the groups regarding birth weight (3006.93 ± 441.86 versus 2949.65 ± 457.36 ...

Background Many neonates admitted to Neonatal Intensive Care Unit (NICU) need mechanical ventilation for recovery. This study was designed to evaluate the short-term outcome of mechanically ventilated neonates admitted to NICU. <span style="fon...
