Comprehensive Assessment of Mid-Regional Proadrenomedullin, Procalcitonin, Neuron-Specific Enolase and Protein S100 for Predicting Pediatric Severe Trauma Outcomes.

The development of multiple organ failure and septic complications increases the cumulative risk of mortality in children with severe injury. Clinically available biochemical markers have shown promise in assessing the severity and predicting the development of complications and outcomes in such cases. This study aimed to determine informative criteria for assessing the severity and outcome prediction of severe injury in children based on levels of mid-regional proadrenomedullin (MR-proADM) procalcitonin (PCT), neuron-specific enolase (NSE), and protein S100.

Brain Biomarkers in Children After Mild and Severe Traumatic Brain Injury.

Brain biomarkers (protein S100b and neuron-specific enolase (NSE)), antibodies (aAb) to the NR2 subunit of N-methyl-D-aspartate (NR2(NMDA)) and to the GluR1 subunit of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (GluR1(AMPA)) subtype of glutamate receptors (GluR), NR2 and AMPA peptides, nitrogen oxides (NOx; "nitrites and nitrates"), and 3-nitrotyrosine (NT) were measured in blood from 159 children after mild traumatic brain injury (mTBI), moderate traumatic brain injury (mdTBI), or severe traumatic brain injury (sTBI) within 1-2 days and at intervals during the first 15 days after brain trauma. S100b and NSE levels on the first day were not a strict criterion for injury outcomes. Children with mTBI had the most significant elevations in antibodies to NR2(NMDA) and AMPA peptides, a slight increase in NOx, and, in 25% of cases, appearance of NT in the blood right after TBI.

Emergence of a ST307 clone carrying a novel insertion element MITEKpn1 in the mgrB gene among carbapenem-resistant Klebsiella pneumoniae from Moscow, Russia.

Carbapenem-resistant Klebsiella pneumoniae (CRKP) represents a major nosocomial pathogen with only a few antimicrobial agents, including colistin, remaining active. However, the emergence of colistin-resistant (Col-R) isolates is compromising the activity of colistin. In this study, a collection of 159 CRKP recovered from three hospitals in Moscow (Russian Federation) was examined.

[The comparison of methods for determination of colistin susceptibility in carbapenem-resistant Klebsiella pneumoniae.].

In recent years, because of carbapenemase spreading in Klebsiella pneumoniae strains, the antibiotic of reserve group, colistin, is increasingly prescribed. In vitro testing of colistin susceptibility in everyday practice has a number of difficulties due to the cationic properties of molecule and weak diffusion into agar. Therefore it is recommended to use the reference Broth Microdilution Method (BMD) for determination of the Minimum Inhibitory Concentration (MIC) for colistin.
