Early diagnosis of sepsis is critical for successful treatment. The clinical value of DcR3 in early diagnosis of sepsis was determined in a dynamic follow-up study. Alterations in plasma levels of DcR3, PCT, CRP, and IL-6 were measured by ELISA and compared among patients with sepsis ( n = 134), SIRS ( n = 60) and normal adults ( n = 50). Correlations and dynamic patterns among the biomarkers, APACHE II scores, clinical outcomes, and pathogens were also examined. Plasma DcR3 was significantly increased in sepsis compared to SIRS and normal adults (median 3...

BACKGROUND: It has been estimated that paediatric meningitis without elevated CSF white cell count (pleocytosis) accounts for 0.5-12% of all cases of bacterial meningitis. CSF protein and glucose measurements are therefore essential in management but may be neglected in clinical practice. In order to improve recognition of bacterial meningitis in neonates and to enable adequate management and audit, we investigated whether a systemic inflammatory response in the absence of meningitis is associated with elevated CSF protein and reduced CSF glucose levels...

BACKGROUND: Trauma and major surgery cause extensive immune hyporeactivity in patients. Thus, the preventive, preoperative application of immunoregulatory therapeutics may normalize this immune reactivity and decrease morbidity and mortality in these subjects. OBJECTIVES: The aim of this study was to investigate the immunomodulatory actions of recombinant human lactoferrin (rhLF) in mice, and to relate these effects to in vitro actions of rhLF on tumor necrosis factor alpha (TNF-α) production in lipopolysaccharide-stimulated whole blood cell cultures (LPS-stimulated WBCC) from patients admitted to intensive care units...

PURPOSE: Patients admitted to cardiac intensive care unit need administration of drugs intravenously often in concomitance of therapeutic techniques such as non-invasive ventilation, continuous renal replacement therapy and intra-aortic balloon counterpulsation. Therefore, the insertion of central venous catheters provides a reliable access for delivering medications, laboratory testing and hemodynamic monitoring, but it is associated with the risk of important complications. In our study, we tested the efficacy and safety of peripherally inserted central catheters to manage cardiac intensive care...

BACKGROUND: Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in the United States, especially in the elderly, who have the highest rates of TBI-related hospitalizations and deaths among all age groups. Sepsis is one of many risk factors that is associated with higher mortality and longer length of hospital stay in this population partially due to the immunosuppressive effects of TBI. The significance of early indicators of infection, such as a positive blood, sputum, or urine culture, is not well described...

BACKGROUND: Necrotizing enterocolitis (NEC) is a leading cause of newborn gastrointestinal emergencies, affecting 1-3 per 1000 live births. Although NEC has been linked to a microbial etiology, associations with maternal intrapartum and resultant newborn early-onset invasive Group B streptococcus (EO-GBS) have been weakly defined. OBJECTIVE: The study aim was to determine the relationship between EO-GBS and NEC. STUDY DESIGN: Data from 2008 to 2015 were collected from pediatric records with ICD diagnosis codes consistent with all stages of NEC, with the exception of neonatal EO-GBS data (only available 2011-2015)...

At an intensive care unit, four neonates died consecutively within 80 minutes. Citrobacter freundii was isolated from blood samples of the 4 patients. It was also cultured from the leftover SMOFlipid that had been infused intravenously into the patients. In this in vitro study, we evaluated the bacterial growth kinetics and change in size of fat globules in SMOFlipid contaminated with C. freundii. Following the growth of bacteria, pH of SMOFlipid decreased to < 6, and the number of fat globules larger than 5 μm increased...

Rapid and accurate profiling of infection-causing pathogens remains a significant challenge in modern health care. Despite advances in molecular diagnostic techniques, blood culture analysis remains the gold standard for diagnosing sepsis. However, this method is too slow and cumbersome to significantly influence the initial management of patients. The swift initiation of precise and targeted antibiotic therapies depends on the ability of a sepsis diagnostic test to capture clinically relevant organisms along with antimicrobial resistance within 1 to 3 h...
