Loyola researchers identify risk factor for life-threatening disease in preemies

17.01.2014
Many premature infants suffer a life-threatening bowel infection called necrotizing enterocolitis (NEC).

Researchers at Loyola University Health System have identified a marker to identify those infants who are at risk for the infection, enabling doctors to employ early preventive strategies. These findings were published in the latest issue of the Journal of Pediatric Surgery.

"This information will allow us to better care for these premature infants," said Jonathan Muraskas, MD, study investigator and co-medical director of Loyola's neonatal ICU. "Simple changes to blood transfusion practices, feeding patterns and treatment of these infants may significantly reduce the incidence of NEC."

NEC is the most common serious gastrointestinal disorder among preterm newborns. It affects up to 10 percent of extremely low birth weight infants and has a mortality rate of nearly 30 percent. There is no known cause for the disease, yet researchers believe it may result from a combination of decreased blood flow to the bowel, feeding patterns, infection, mechanical injury or abnormal immune response.

NEC occurs when the lining of the intestinal wall dies and tissue falls off. Most cases of NEC are mild to moderate and can be successfully treated with antibiotics. But in severe cases, a hole can develop in the intestine, allowing bacteria to leak into the abdomen causing a life-threatening infection.

This study evaluated 177 infants born at less than 32 weeks' gestation and/or babies who were less than 3 pounds, 3 ounces. Blood samples were collected from these infants within 72 hours of birth and weekly for four weeks to measure reticulated platelets (RP) and intestinal alkaline phosphatase (iAP). Of the 177 infants, 15 (8.5 percent) developed NEC. Of these, 93 percent had low RP levels and 60 percent had high iAP. Those infants with low RP levels were significantly more likely to develop NEC while those with high iAP showed a similar trend.

"Decreased reticulated platelets serve as a sensitive indicator for NEC onset," Dr. Muraskas said. "Further research also may find that infants with elevated iAP levels may be at risk for this serious illness."

This study was conducted in collaboration with Richard Kampanatkosol, MD, Tricia Thomson, MD, Phillip DeChristopher, MD, Sherri Yong, MD, and Walter Jeske, PhD, from Loyola University Health System; Omar Habeeb, MD, from Hutt Valley District Health Board, in Wellington, New Zealand; Loretto Glynn, MD, from Ann and Robert H. Lurie Children's Hospital at Cadence Health; and Akhil Maheshwari, MD, from University of Illinois at Chicago.

Loyola has one of the premier neonatal ICUs in the Midwest. It has cared for more than 25,000 babies and holds the Guinness world record for the smallest surviving baby (9.2 ounces).

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
