OBJECTIVE We examined whether maternal smoking and use of nicotine substitutes during the first 12 weeks of pregnancy increased the prevalence of congenital malformations in general and of certain congenital malformations in particular. METHODS In the Danish National Birth Cohort (1997-2003) we identified 76,768 pregnancies (and their subsequent singleton births); 20,603 were exposed to tobac...

It was hypothesized that a short interpregnancy interval immediately following the birth of an infant that had succumbed to sudden infant death syndrome (SIDS) (and no other cause of death) would be associated with a reduced mean birth weight in the next infant. Mothers who had given birth to two children in the state of Oregon between 1975 and 1984 and whose first child had died in infancy fro...

In this experiment, 98 multiparous Yorkshire sows blocked on farrowing date were randomly assigned to four treatments in a 2 x 2 factorial arrangement. Oxygen inhalation (6 L/min) by the sow was tested in an effort to reduce stillbirth rate and improve pig viability. This study also tested the effect of increasing uterine contractions using neostigmine (5 mg) to determine whether simultaneous a...

BACKGROUND The one-step method was routine practices in China, scientific evidence to support this intervention is scarce. The purpose of this study was to observe the natural process of head-to-body delivery interval by waiting for at least one contraction (two-step) after head delivered in normal birth. METHODS From March 1 to March 30 in 2015 at Haikou Maternal and Child Hospital in China,...

OBJECTIVE Treatment delays in breast cancer are generally thought to affect prognosis but the impact on survival remains unclear. Indicators for breast cancer care include time to primary treatment. The purpose of this study was to evaluate whether time to primary treatment (TPT) in breast cancer impacts survival. METHOD A total of 648 breast cancer patients treated in the University Malaya M...
