Summary
Maternal hypertensive disease did not significantly increase the risk of necrotizing enterocolitis (NEC). However, intrauterine growth restriction and lower birth weight were identified as key risk factors for NEC in neonates.
Area of Science:
- Neonatal Medicine
- Perinatal Research
- Pediatric Surgery
Background:
- Necrotizing enterocolitis (NEC) is a serious gastrointestinal condition affecting newborns.
- Maternal hypertensive disorders are common pregnancy complications.
- The association between maternal hypertensive disease and neonatal NEC requires further investigation.
Purpose of the Study:
- To examine the relationship between maternal hypertensive disease and other risk factors with the development of neonatal necrotizing enterocolitis (NEC).
Main Methods:
- Retrospective case-control study of singleton neonates diagnosed with NEC between 2008 and 2012.
- Maternal hypertensive disease was the primary exposure of interest.
- Data on demographics, pregnancy complications, medications, and neonatal outcomes were collected from medical records.
Main Results:
- No significant association was found between maternal hypertensive disease and neonatal NEC.
- Antenatal diagnosis of intrauterine growth restriction (p=0.008) and lower neonatal birth weight (p=0.009) were significantly associated with increased NEC risk.
- Infants with NEC exhibited higher rates of late-onset sepsis (p=0.01) and mortality (p=0.001).
Conclusions:
- Intrauterine growth restriction and lower birth weight are significant risk factors for neonatal NEC.
- While not statistically significant, a nearly two-fold increased risk for NEC was observed with maternal hypertensive disease, suggesting potential underpowering of the study.
- Further research with larger cohorts is warranted to clarify the role of maternal hypertensive disease in NEC pathogenesis.

Development of the Oral Microbiota
60
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,...

Bacterial Gastroenteritis
83
Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Bacterial Meningitis II: Pathophysiology
10
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Intestinal Obstruction II: Pathophysiology
37
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Development of Human Microbiota
59
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...

Necrosis
5.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...
