BACKGROUND Higher risks of stillbirth or early neonatal death, or both, have been reported from several countries for births on weekend days. It is unclear whether such higher risks have persisted in recent years. We investigated weekend-associated risks of stillbirth and early neonatal death in most Canadian provinces. METHODS We studied all 3 239 972 births recorded in Canada, excluding Ont...

BACKGROUND Caesarean section (CS) rates are increasing worldwide and as a result repeat CS is common. The optimal mode of delivery in women with one previous CS is widely debated and the risks to the infant are understudied. The aim of the current study was to evaluate if women with a trial of labour after caesarean (TOLAC) had an increased odds of neonatal and infant death compared to women wi...

OBJECTIVE Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. METHODS A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information Syste...

BACKGROUND Almost all (99%) neonatal deaths arise in low-income and middle-income countries. Approximately 450 new-born children die every hour, which is mainly from preventable causes. There has been increased recognition of the need for these countries to implement public health interventions that specifically target neonatal deaths. The purpose of this paper is to identify the predictors of ...

Hindbrain neuronal networks serving respiratory, proprioceptive, and arousal functions share a developmental requirement for the bHLH transcription factor Atoh1. Loss of Atoh1 in mice results in respiratory failure and neonatal lethality; however, the neuronal identity and mechanism by which Atoh1-dependent cells sustain newborn breathing remains unknown. We uncovered that selective loss of Ato...

BACKGROUND Neonatal infection with herpes simplex virus (HSV) is not a nationally reportable disease; there have been few population-based measures of HSV-related infant mortality. We describe infant death rates due to neonatal HSV as compared with congenital syphilis (CS) and HIV, 2 reportable, perinatally transmitted diseases, in New York City from 1981 to 2013. METHODS We identified neonat...

Pregnancy in the women aged less than 20 years is an important public health issue, especially in developing countries. In Iran, limited studies have focused on the effects of maternal age on gestational and neonatal outcomes to demonstrate the pregnancy outcomes in young women. The present study aimed to investigate the maternal and neonatal complications in the pregnant women aged less than 2...

OBJECTIVE We sought to determine the contribution of withholding or withdrawing care to neonatal mortality in our hospital over a 10-year period from 1993 through 2002. BACKGROUND Although not initiating or withholding intensive care for certain newborns has been practiced openly for the past 25 years, little information has been published concerning the results of these practices on neonatal...

Exposure to high concentrations of oxygen in the neonatal period may impair lung growth and is a major contributing factor to the development of bronchopulmonary dysplasia. Cell death from hyperoxic injury may occur through either an apoptotic or nonapoptotic pathway, and we were interested in determining the type of cell death that occurs in the lung of neonatal mice exposed to hyperoxia. We f...
