Fetal Echocardiography and Pulsed-wave Doppler Ultrasound in a Rabbit Model of Intrauterine Growth Restriction
Published on: June 29, 2013
Resumen
El retraso del crecimiento placentario condujo a muertes fetales y neonatales significativas. Los factores de riesgo incluyen presión arterial materna alta, proteinuria, mayor edad materna, anemia y pobreza, lo que indica una mala perfusión placentaria y desnutrición fetal.
Área de la Ciencia:
- Obstetricia y Ginecología.
- La medicina perinatal es una medicina que se desarrolla en el perinatal.
- Desarrollo fetal y desarrollo fetal.
Sus antecedentes:
- El retraso del crecimiento placentario (PGR) es una complicación obstétrica crítica.
- PGR contribuye significativamente a la mortalidad y morbilidad perinatal.
Objetivo del estudio:
- Investigar las causas y los factores que contribuyen a las muertes fetales y neonatales asociadas con el retraso del crecimiento placentario.
- Identificar las características maternas y placentarias vinculadas a la mortalidad relacionada con el PGR.
Principales métodos:
- Análisis retrospectivo de muertes fetales y neonatales atribuidas a retraso en el crecimiento de la placenta.
- Evaluación de los factores maternos, incluida la presión arterial, la proteinuria, la edad, la anemia y el estado socioeconómico.
- Examen microscópico de los tejidos placentarios y deciduos para detectar pruebas de perfusión inadecuada.
Principales resultados:
- El retraso del crecimiento placentario representó 84 muertes fetales y neonatales por cada 100.000 nacimientos.
- El aumento de la presión arterial diastólica materna y la proteinuria aumentaron el riesgo de muerte.
- Las muertes perinatales se correlacionaron con el avance de la edad materna, la anemia y la pobreza.
- Se observó un bajo aumento de peso materno y signos de desnutrición fetal.
- La patología placentaria indicó una perfusión uterina inadecuada, incluidos cambios fibrinoides y endarteritis.
Conclusiones:
- El retraso del crecimiento placentario es una de las principales causas de muerte perinatal, asociada con hipertensión materna, proteinuria y factores socioeconómicos adversos.
- Los hallazgos patológicos sugieren que la perfusión uteroplacentaria alterada es un mecanismo clave.
- Abordar la salud materna y los factores socioeconómicos puede mitigar la mortalidad relacionada con la PGR.

01:07Teratogenicity
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...
01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

01:14Fetal 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...

01:20Inborn Errors of Metabolism
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...
01:22Diabetes Mellitus: Type 2 and Gestational
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...
01:20Pathophysiology of Diabetes
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility, suggesting a...
