Summary
Chorioamnionitis, an infection during pregnancy, impacts preterm birth outcomes. While it may reduce respiratory issues, it can increase risks for other complications in newborns.
Area of Science:
- Neonatal Medicine
- Obstetrics
- Perinatal Research
Background:
- Chorioamnionitis is a significant risk factor for preterm birth, leading to neonatal morbidity and mortality.
- Heterogeneity in study designs complicates understanding neonatal outcomes following chorioamnionitis exposure.
- Advances in perinatal care have altered the evident impact of in utero inflammation on neonatal outcomes.
Purpose of the Study:
- To clarify the complex effects of chorioamnionitis on neonatal outcomes.
- To analyze the association between histological and clinical chorioamnionitis and infant health.
- To evaluate the impact of intra-uterine inflammation on specific neonatal morbidities.
Main Methods:
- Comparative analysis of existing studies on neonatal outcomes after chorioamnionitis exposure.
- Review of data concerning histological and clinical definitions of chorioamnionitis.
- Examination of the relationship between chorioamnionitis and respiratory distress syndrome, bronchopulmonary dysplasia, sepsis, and brain lesions.
Main Results:
- Histologic chorioamnionitis is linked to reduced respiratory distress syndrome but may increase bronchopulmonary dysplasia risk in extremely premature infants.
- Chorioamnionitis is associated with increased early-onset sepsis but potentially protective against late-onset sepsis.
- Evidence on chorioamnionitis's role in brain lesions like PVL, DWM, and IVH is inconsistent, though an association with cerebral palsy exists.
Conclusions:
- The neonatal effects of chorioamnionitis are multifaceted, with varying impacts on respiratory and neurological outcomes.
- Histological chorioamnionitis presents a complex risk-benefit profile for extremely preterm infants.
- Further research is needed to reconcile inconsistent findings and clarify chorioamnionitis's precise role in neonatal brain injury and long-term neurodevelopmental outcomes.

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...
01:28Acute Pyelonephritis II: Diagnostic Studies and Management
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
01:28Development 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,...
01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
01:15Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
