BACKGROUND: Simultaneous determination of the two main actin scavenger proteins in sepsis has not been investigated until now. In our pilot study, we elucidated the predictive values of Gc globulin and gelsolin (GSN) in sepsis by comparing them to classic laboratory and clinical parameters. METHODS: A 5-day follow-up was performed, including 46 septic patients, 28 non-septic patients and 35 outpatients as controls. Serum Gc globulin and GSN levels were determined by automated immune turbidimetric assay on a Cobas 8000/c502 analyzer...

PURPOSE: There has been much recent interest in the use of procalcitonin (PCT) as a marker of intra-abdominal infection (IAI) following colorectal surgery. However, the literature remains divided on the value of PCT in this setting. This meta-analysis aims to evaluate the value of PCT in predicting IAI after colorectal surgery. METHODS: Systemic literature search was performed using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews to identify studies evaluating the diagnostic accuracy of PCT as a predictor for detecting IAI on postoperative days (POD) 3 to 5 following colorectal surgery...

A healthy woman volunteered to participate as "healthy control" in a study. An increased level of procalcitonin (PCT) was detected and remained elevated on follow-up measurements. As calcitonin levels were elevated as well, thyroid ultrasound was performed which revealed nodes in both thyroid lobes, one of them showing metabolic activity in positron emission tomography-computed tomography scan. To exclude a malignant thyroid cancer despite the negative findings in a fine needle aspiration the patient underwent thyroidectomy and a medullary thyroid carcinoma (MTC) was detected in the right lobe...

Nanomaterials themselves as redox probes and nanocatalysts have many advantages for electrochemical biosensors. However, most nanomaterials with excellent catalytic activity cannot be directly used as redox probe to construct electrochemical biosensor because the redox signal of these nanomaterials can only be obtained in strong acid or alkali solution at high positive or negative potential, which greatly limits their applications in biologic assay. In this study, Cu/Mn double-doped CeO2 nanocomposite (CuMn-CeO2) was synthesized to use as signal tags and signal amplifiers for the construction of electrochemical immunosensor for sensitive assay of procalcitonin (PCT)...

AIMS OF THE STUDY: While studies show that antibiotic treatment for uncomplicated diverticulitis seems to have no benefit, most experts advocate antimicrobial therapy for complicated diverticulitis. However, even for uncomplicated diverticulitis, most clinicians are very reluctant to withhold antibiotics. Biomarkers could help to guide antibiotic therapy as this approach has been shown to be effective for acute respiratory infections. In this diagnostic cohort study we evaluated whether procalcitonin could be a biomarker to distinguish complicated from uncomplicated cases of diverticulitis...

OBJECTIVE: There is increasing data in pediatrics demonstrating procalcitonin (PCT) is more sensitive and specific than other biomarkers in the setting of bacterial infections. However, the use of PCT in neonatal and pediatric extracorporeal membrane oxygenation (ECMO) is not well described. Therefore, the purpose of this study was to describe the clinical utility of PCT in determining the absence or presence of bacterial infections in neonatal and pediatric patients on ECMO. METHODS: This was a retrospective electronic medical record (EMR) review of data between January 1, 2010 to June 30, 2016 at a single, free-standing, children 's hospital...

BACKGROUND: Postoperative pneumonia is frequent after cardiac surgery and is associated with increased morbidity and mortality. We tested the hypothesis that endocan is an early biomarker for the detection of pneumonia after cardiac surgery. METHODS: Between January and May 2016, 155 patients scheduled to undergo elective cardiac surgery with cardiopulmonary bypass were prospectively included in the study. Serum level of endocan was measured at five timepoints (preoperative, and at 6, 24, 48, and 72 hours after the end of surgery)...

Due to overlap of clinical findings and low sensitivity of bacterial diagnostic tests, differentiation between bacterial and viral respiratory tract infections remains challenging, ultimately leading to antibiotic overuse in this population of patients. Addition of procalcitonin, a blood biomarker expressed by epithelial cells in response to bacterial infections, to the clinical assessment leads to a reduction in inappropriate antibiotic initiation. Procalcitonin also provides prognostic information about the resolution of illness, and significant decreases over time are a strong signal for the discontinuation of antibiotics...

The management of children with fever without apparent sources (FWAS) is difficult. This study aimed to evaluate the diagnostic accuracy of procalcitonin (PCT) in detecting serious or invasive bacterial infection (SBI or IBI) in children with FWAS. Areas covered: A systematic review of literature from 2007 to 2017 was performed on Medline. Twelve studies were included, involving 7,260 children with FWAS and analyzing the diagnostic performance of PCT. Four meta-analyses were performed to calculate pooled sensitivity, specificity, diagnostic odds ratio, and summary receiver operating characteristic curve for PCT in detecting SBI and IBI, at two different thresholds...
