Viruses are obligatory intracellular pathogens and completely depend on their hosts for survival and reproduction. The strategies adopted by viruses to exploit host cell processes and to evade host immune systems during infections may differ largely with the type of the viral genetic material. An improved understanding of these viral infection mechanisms is only possible through a better understanding of the pathogen-host interactions (PHIs) that enable viruses to enter into the host cells and manipulate the cellular mechanisms to their own advantage...

Unwitnessed penetrating head injuries (PHIs) are often challenging. The inability to locate a foreign body should not exclude this diagnosis nor should it delay treatment. Attempts must be made to clarify the mechanism of injury, as this may allow for a better understanding of the patient's condition.

An effective analytical method was developed for the detection and quantification of polyoxin D in butterbur using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Samples were extracted using acidified deionised water and purified via solid-phase extraction (SPE) using an HLB cartridge. An external matrix-matched standard calibration curve was prepared, which provided an excellent linearity with a coefficient of determination (R(2)) ⩾0.999. Limits of detection (LOD) and quantification (LOQ) were 0...

BACKGROUND: Traumatic brain injury (TBI) causes substantial morbidity and mortality in US children. Post-traumatic seizures (PTS) occur in 11-42% of children with severe TBI and are associated with unfavorable outcome. Electroencephalographic (EEG) monitoring may be used to detect PTS and antiepileptic drugs (AEDs) may be used to treat PTS, but national rates of EEG and AED use are not known. The purpose of this study was to describe the frequency and timing of EEG and AED use in children hospitalized after severe TBI...

Black patients with acute myeloid leukemia (AML) experience higher mortality than White patients. We compared induction mortality, acuity of illness prior to chemotherapy, and insurance type between Black and White patients to assess whether acuity of presentation mediates the disparity. Within a retrospective cohort of 1,122 children with AML treated with two courses of standard induction chemotherapy between 2004 and 2014 in the Pediatric Health Information System (PHIS) database, the association between race (Black versus White) and inpatient mortality during induction was examined...

We sought to examine the relationship between liver transplant-related total cost, patient outcome, and hospital resource utilization at freestanding children's hospitals. Using the PHIS database, a retrospective study of 374 patients that underwent liver transplantation at 15 freestanding children's hospitals from July 2010 to December 2012 was performed. One-year graft failure and patient mortality rates from July 2010 to December 2012 for each center were also obtained from the SRTR. There was a 5.1-fold difference in median cost (median $146 444, range $59 487-302 058, P<...

BACKGROUND: In the case of the hemodynamically unstable child, splenorrhaphy is preferred to splenectomy to avert postsplenectomy sepsis. However, successful splenorrhaphy requires familiarity with the procedure. We sought to determine how many splenectomies or splenorrhaphies for trauma the average pediatric surgeon can be expected to perform during their career. METHODS: The Pediatric Health Information System (PHIS) Database was queried for patients ≤18years coded with an International Classification of Diseases 9th Edition diagnosis code of a splenic injury from 2004 to 2013...

Whereas phosphorylation of serine, threonine, and tyrosine is exceedingly well characterized, the role of histidine phosphorylation in mammalian signaling is largely unexplored. Here we show that phosphoglycerate mutase family 5 (PGAM5) functions as a phosphohistidine phosphatase that specifically associates with and dephosphorylates the catalytic histidine on nucleoside diphosphate kinase B (NDPK-B). By dephosphorylating NDPK-B, PGAM5 negatively regulates CD4(+) T cells by inhibiting NDPK-B-mediated histidine phosphorylation and activation of the K(+) channel KCa3...
