This study sought to determine whether a change in twinning prevalence was associated with mandatory folic acid fortification. As of January 1998, it became mandatory in the United States that grain products be fortified with folic acid. The effectiveness of this fortification for neural tube defects has been explored, but ...

The development of fetal surgery has led to promising therapeutic options for a number of congenital malformations. However, preterm labor (PTL) and premature rupture of membranes continue to be ubiquitous risks for both mother and fetus. To reduce maternal morbidity and the risk of prematurity, minimal access surgical techniques were ...

OBJECTIVES: Twin studies present a unique opportunity to examine the association of birth weight with adult life phenotypes in a design that naturally accounts for maternal factors and a range of early environmental factors, which might potentially bias the association. In this study, we explored the association of birth weight ...

BACKGROUND: Retained second twin contributes significantly to perinatal morbidity and mortality, as well as maternal morbidity and mortality, usually arising as a result of intervention to salvage the retained foetus. OBJECTIVE: To review the current incidence, management, fate and outcome of both the retained foetus and its mother, with a ...

Low birth weight is associated with an increased risk of atherothrombosis, which may be related in part to the association between low birth weight and high plasma fibrinogen. The association between birth weight and fibrinogen may be explained by intrauterine, socio-economic or genetic factors. We examined birth weight and fibrinogen ...

BACKGROUND: In the wide-ranging debate about the potential monitors of population fertility, twinning rate has been considered a candidate. In the developed countries, a decline in spontaneous twinning rate began around 1950 and continued until the late 1970s. The decrease in mean maternal age at delivery and the number of ...

Our primary objective in this study was to test the multiple birth hypothesis, which asserts that multiple gestation and delivery, per se, entail a greater likelihood of adverse outcome than for singletons. Our second objective was to assess the power of various neonatal risk indicators to predict developmental status at ...
Shinwell E S - - 2003
BACKGROUND: Neonatal morbidity and mortality differ between singletons, twins, and triplets. OBJECTIVE: To evaluate whether plurality is associated with excess risk of neonatal morbidity and poor outcome (death, chronic lung disease, or adverse neurological findings) in very low birthweight (VLBW) infants from a national, population based cohort. METHODS: The Israel ...

The major morphological types of conjoined twins had all been described by 1600, often in publications that included details of the time and place of birth, morphology, outcome, behaviour, and, on occasion, autopsy findings. These descriptions differ from modern reports in emphasizing the twins' supposed "meaning" rather than their cause. ...

BACKGROUND/PURPOSE: Conjoined twins are some of the most challenging patients faced by surgeons. Pygopagus and ischiopagus twins present particular gastrointestinal and genitourinary reconstructive challenges. This study reviews the authors' experience with the perineal reconstruction of these types of conjoined twins. METHODS: Retrospective analysis was performed for 3 sets of female ...
Misra Dawn P - - 2002
OBJECTIVE: Whereas it is well-established that maternal age has a U-shaped relationship with infant mortality among singletons, effects on the risk of mortality among multiple births remains unexplored. If there is a relationship, then assessment of maternal age may identify pregnancies and births that should be targeted by both clinical ...
