Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Fetal Circulation01:14

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Summary
This summary is machine-generated.

The incidence of births before 33 weeks of gestation significantly increased threefold over 12 years. While induced prematurity did not rise, cesarean sections for induced preterm labor increased, highlighting a growing concern in France.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatal Perinatal Medicine
  • Public Health Epidemiology

Background:

  • Preterm birth before 33 weeks of amenorrhea (SA) is a significant concern in neonatal and perinatal medicine.
  • Understanding the trends and causes of early preterm birth is crucial for developing effective interventions.

Purpose of the Study:

  • To evaluate the incidence of births before 33 SA over a 12-year period.
  • To determine the role of induced prematurity and its causes.
  • To analyze the evolution of etiologies leading to preterm birth.

Main Methods:

  • Retrospective study of 3781 deliveries between 22 and 32+6 weeks of gestation (1994-2006).
  • Utilized the Network Users Association of computerized records in Pediatrics, Obstetrics and Gynecology (AUDIPOG) database.
  • Statistical analysis of prematurity degree, type, mode of delivery, and etiologies.

Main Results:

  • Births before 33 SA tripled over 12 years, reaching 1.7% of total births in 2006.
  • No increase in induced prematurity, but a significant rise in cesarean sections for induced preterm labor.
  • Vaginal/urinary infections and fetal malformations decreased as causes; multiple pregnancies significantly increased.
  • Hypertension was the primary cause of preterm birth; metrorrhagia and infections were more prevalent before 28 SA.

Conclusions:

  • The increasing incidence of births before 33 SA is a serious public health issue requiring ongoing monitoring in France.
  • While overall induced prematurity is stable, changes in delivery methods for induced preterm labor warrant attention.
  • Identifying and addressing the evolving causes of preterm birth, such as hypertension and multiple pregnancies, is essential.
