(Press-News.org) Scientists from Stanley Manne Children’s Research Institute at Ann & Robert H. Lurie Children’s Hospital of Chicago and colleagues found that an investigational protein replacement – recombinant human insulin-like growth factor 1 and its binding protein-3 (rhIGF-1/BP3) – protected neonatal mice from necrotizing enterocolitis (NEC), a deadly intestinal disease that often strikes extremely premature infants. Results were published in the journal Pediatric Research.
“Our preclinical evidence is encouraging and paves the way to a clinical trial of rhIGF-1/BP3 for prevention of NEC,” said senior author Isabelle De Plaen, MD, a scientist at Manne Research Institute, neonatologist at Lurie Children’s, and Professor of Pediatrics at Northwestern University Feinberg School of Medicine. “The rhIGF-1/BP3 is already in Phase 2 clinical trials for preventing bronchopulmonary dysplasia (BPD) and retinopathy of prematurity (ROP), both of which are severe complications affecting the lungs and eyes in extremely premature babies. Our results could help add NEC to these clinical trials.”
Previous studies have shown that low levels of the naturally occurring insulin-like growth factor 1 (IGF-1) are associated with increased risk of BPD, ROP and NEC in preemies.
In Dr. De Plaen’s study, supplementing with rhIGF-1/BP3 protected intestinal microvasculature development and decreased inflammation, which might be how NEC was prevented. Her group’s previous research has shown that defective intestinal microvascular development significantly contributes to NEC.
“Currently we don’t have curative therapy for NEC, so prevention is a highly promising approach,” said Dr. De Plaen. “Our goal is to spare premature infants from this devastating disease and other complications of prematurity.”
Research at Ann & Robert H. Lurie Children’s Hospital of Chicago is conducted through Stanley Manne Children’s Research Institute, which is focused on improving child health, transforming pediatric medicine and ensuring healthier futures through the relentless pursuit of knowledge. Lurie Children’s is a nonprofit organization committed to providing access to exceptional care for every child.

Pancreatic cancer lives on mucus
2024-02-28
Knowing exactly what’s inside a tumor can maximize our ability to fight cancer. But that knowledge doesn’t come easy. Tumors are clusters of constantly changing cancer cells. Some become common cancer variants. Others morph into deadlier, drug-resistant varieties. No one truly understands what governs this chaotic behavior.
Now, Cold Spring Harbor Laboratory (CSHL) Professor David Tuveson and his team have uncovered a mechanism involved in pancreatic cancer transformation—mucus. During the disease’s early stage, pancreatic cancer cells produce mucus. Additionally, these cells depend on the body’s regulators of mucus production. This new ...
Want fewer microplastics in your tap water? Try boiling it first
2024-02-28
Nano- and microplastics are seemingly everywhere — water, soil and the air. While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee. As reported in ACS’ Environmental Science & Technology Letters, boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.
Contamination of water supplies with nano- and microplastics (NMPs), which can be as small as one thousandth of a millimeter ...

Shedding light on the intricacies of numerical simulations of soil behavior
2024-02-28
A solid understanding of soil mechanics and behavior is one of the fundamental pillars of geotechnical engineering. The stability and resilience of many modern geotechnical structures, including building foundations, dams, bridges, and embankments, rely on appropriate modelling based on accurate measurements of soil properties.
Over the past few decades, unprecedented growth in computing power has turned numerical simulations of soil behavior into an attractive tool in geotechnical engineering. By representing soil as a set of interacting particles, numerical simulations can help researchers understand complex soil behavior under various conditions. Moreover, numerical ...

Understanding genetic risk could save sight and predict multiple sclerosis earlier in young people
2024-02-28
Young people could be spared from going blind by a new genetic risk tool that could also help diagnose multiple sclerosis (MS) earlier, to start effective treatments.
Optic neuritis is a condition that affects people of all ages, but especially young adults, usually manifesting in blurred vision and sometimes pain when moving the eyes. Up to half of people affected in the UK eventually go on to develop MS – often many years later. Emerging evidence indicates that starting the very effective MS treatments earlier may improve long term health.
Optic neuritis occurs because of swelling in or around the optic nerve. For those with MS-related optic neuritis, the swelling subsides ...
Cannabis use linked to increase in heart attack and stroke risk
2024-02-28
Research Highlights:
An analysis of survey data for 430,000 adults in the U.S. found that using cannabis has a significant association with an increased risk of heart attack and stroke, independent of tobacco use, with higher odds among the adults with more frequent use (more days of use per month). The most common method of cannabis use was smoking, followed by eating or vaporizing it.
The increase in the combined risk of coronary heart disease, heart attack and stroke was similar to the risk among the subset of adults who had never used e-cigarettes but did use cannabis.
