Summary
Multiple transfusions of packed red blood cells increase the risk of necrotizing enterocolitis in very low birth weight infants. Other factors did not identify infants at risk, warranting caution with transfusions.
Area of Science:
- Neonatalogy
- Pediatric Gastroenterology
- Critical Care Medicine
Background:
- Necrotizing enterocolitis (NEC) is a severe gastrointestinal emergency in premature infants.
- Identifying risk factors for NEC is crucial for prevention and management in vulnerable neonates.
Purpose of the Study:
- To identify risk or protective factors associated with the development of necrotizing enterocolitis (NEC).
- To investigate the role of packed red blood cell transfusions as a potential factor in NEC development.
Main Methods:
- Retrospective case-control study involving very low birth weight infants (<1500 g).
- Infants diagnosed with NEC were compared to matched controls.
- Unadjusted and multivariable statistical analyses were performed.
Main Results:
- 30 out of 576 very low birth weight infants (5.2%) developed NEC.
- No significant differences in main clinical or demographic characteristics between cases and controls.
- Increased odds of NEC were associated with a higher number of packed red blood cell transfusions (OR 1.5, 95% CI [1.01 to 2.24]).
Conclusions:
- A higher number of packed red blood cell transfusions is linked to an increased risk of NEC in very low birth weight infants.
- Other analyzed variables did not significantly identify infants at risk for NEC.
- Clinical caution is advised regarding the use of transfusions in newborn infants.

01:18Bacterial Gastroenteritis

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...

01:26Factors Affecting the Risk of Infection
14.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

01:07Intestinal Obstruction II: Pathophysiology
47
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...

01:30Development of Human Microbiota
61
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...

35
Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...
