Resumen
La oligohidramnios aislada es un factor de riesgo significativo para la edad gestacional pequeña (SGA). Este metanálisis confirma que las mujeres embarazadas con oligohidramnios aislados requieren una mayor vigilancia para el desarrollo de SGA.
Área de la Ciencia:
- Obstetricia y ginecología
- Medicina perinatal
- Salud Reproductiva
Sus antecedentes:
- Existen datos limitados sobre la asociación entre oligohidramnios aislados y el riesgo de pequeños para la edad gestacional (SGA).
- Se necesita un metanálisis exhaustivo para aclarar esta relación.
Objetivo del estudio:
- Investigar la asociación entre la oligohidramnios aislada y el riesgo de desarrollar un pequeño para la edad gestacional (SGA).
Principales métodos:
- Búsqueda sistemática de la literatura de PubMed, Web of Science, Scopus y Science Direct hasta el 26 de febrero de 2024.
- Metaanálisis del modelo de efectos aleatorios, incluidas las evaluaciones de la heterogeneidad y el sesgo de publicación.
- Evaluación de la calidad de los estudios observacionales mediante la escala modificada de Newcastle-Ottawa (NOS).
Principales resultados:
- Se incluyeron siete estudios en este metanálisis.
- La oligohidramnios aislada se asoció con un mayor riesgo de SGA (OR bruta: 2,22, OR ajustada: 2,18).
- El análisis ajustado no mostró una heterogeneidad significativa (I2 = 0,0%).
Conclusiones:
- La oligohidramnios aislada es un factor de riesgo significativo para la edad gestacional pequeña (SGA).
- Las mujeres embarazadas diagnosticadas con oligohidramnios aislados deben someterse a monitoreo para la detección de SGA.

Pathophysiology of Diabetes
1.2K
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,...

Teratogenicity
2.7K
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...

Diabetes Mellitus: Type 2 and Gestational
2.9K
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...

Meiosis vs. Mitosis
58.1K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
