Boulet Sheree L - - 2006
BACKGROUND: Although increases in perinatal mortality risk associated with fetal macrosomia are well documented, the optimal route of delivery for fetuses with suspected macrosomia remains controversial. The objective of this investigation was to assess the risk of neonatal death among macrosomic infants delivered vaginally compared with those delivered by cesarean ...
Bloom Steven L - - 2006
BACKGROUND: Knowledge of fetal oxygen saturation, as an adjunct to electronic fetal monitoring, may be associated with a significant change in the rate of cesarean deliveries or the infant's condition at birth. METHODS: We randomly assigned 5341 nulliparous women who were at term and in early labor to either "open" ...

One of the biggest challenges a newborn faces after birth is the task of making a smooth transition to air breathing. This task is complicated by the fact that fetal lungs are full of fluid which must be cleared rapidly to allow for gas exchange. Respiratory morbidity as a result ...

A number of competing risks and benefits influence the rates of neonatal morbidity and mortality in elective cesarean delivery versus expectant management. To compare these rates, we developed complex decision trees to model the expected outcomes among hypothetical cohorts of 1,000,000 uncomplicated pregnancies undergoing elective cesarean delivery versus 1,000,000 comparable ...

In situ infrared (IR) and Raman microspectroscopy have been conducted on Neoproterozoic, organic-walled microfossils (prokaryotic fossils) in doubly polished, petrographic thin sections in order to detect their spectral signatures. The microfossils are very well preserved and occur in black chert from the approximately 850 million-year-old Bitter Springs Formation, Northern Territory, ...

Brazil has one of the world's highest cesarean section rates. Contributing factors include the organization of obstetric practice, physicians' attitudes, and women's preferences and decisions. This study aimed to identify factors associated with cesarean sections in a public maternity hospital in Rio de Janeiro. A case-control study was conducted with ...
Handa Victoria L - - 2006
OBJECTIVE: This manuscript reviews the potential impact of cesarean delivery on maternal sexual function. FINDING: The majority of new mothers resume intercourse within the first 3 months after delivery. However, during the first year after delivery, the majority of women experience at least one problem related to sexual function. The ...
Wax Joseph R - - 2006
Since no randomized trial evaluates maternal morbidity from planned cesarean versus planned vaginal delivery, the issue must be addressed indirectly from retrospective cohort studies of vertex fetuses by actual or planned delivery route, and retrospective or randomized studies of breech fetuses by planned delivery route. The available data, although limited, ...
Ross Michael G - - 2006
BACKGROUND: In the management of shoulder dystocia, fetal head replacement into the uterus has been advocated should delivery attempts remain unsuccessful.

There is enormous geographic variation in the use of cesarean delivery: For births over 2,500 grams, adjusted cesarean rates vary fourfold between low- and high-use areas. Even for births under 2,500 grams, high-use counties have rates that are double those of low-use ones. Higher cesarean rates are only partially explained ...

Four Macaca nemestrina infants delivered via cesarean section were introduced to their mothers after surgery. All 4 introductions were successful, although methods differed slightly between dam-infant pairs.

AIMS: Sacrococcygeal teratomas (SCTs) are the commonest neonatal tumors with an incidence of approximately 1:30,000. There are few large single-center series and even fewer describing both their antenatal and postnatal course. We report the outcome of all fetuses investigated at a tertiary fetal medicine center with this diagnosis. METHOD: Demographic ...
Gonen Ron - - 2006
OBJECTIVE: It has been claimed that a trial of labor after cesarean carries higher maternal and fetal risks than planned cesarean delivery. Because the management of such patients in our department differs from that described in some studies, and is perhaps more cautious, we hypothesized that the outcome may be ...
Bailit Jennifer L - - 2006
OBJECTIVE: The purpose of this study was to examine the association between risk-adjusted primary cesarean delivery rates and maternal and neonatal outcomes. STUDY DESIGN: California birth certificate data that were linked to hospital discharge data for 2001 were used to create a primary cesarean delivery rate risk-adjustment model. Two hundred ...

Newborn rats maintain mother-litter bonds by using olfactory signals. At birth, units in the olfactory glomeruli (OG) are immature and vulnerable to noxious epigenetic factors like undernutrition. Because little is known about the effects of neonatal undernutrition upon the OG morphological organization, different OG parameters were studied in undernourished Wistar ...
