BACKGROUND: Procalcitonin (PCT) is a known diagnostic marker of bacterial infection. There are no previous reports of PCT concerning acute liver failure (ALF). We evaluated the clinical value of serum PCT levels in patients with ALF. METHODS: Forty-four patients with acute hepatitis (19 men and 25 women; median age, 40 years; range, 20-79 years) were retrospectively enrolled from January 2001 and June 2015. PCT levels were measured by saved serum samples obtained within 3 days after admission...

Macrophage activation syndrome (MAS) is one of the serious complications associated with rheumatic diseases, especially systemic juvenile idiopathic arthritis (sJIA). Here we describe a 9-year-old girl with rheumatoid factor (RF)-positive polyarticular JIA, not sJIA, combined with pneumonia who was successfully treated by plasma exchange. She was diagnosed with RF-positive polyarticular JIA based on positive RF and multiple joint swelling and tenderness 3 years ago. She was admitted in our hospital with myalgia for 2 days and a high fever for half a day...

Porphyrias are a group of intriguing genetic diseases of the heme pathway, of which porphyria cutanea tarda (PCT) is the most common. Resulting from a defect in enzymes in the porphyria pathway, PCT has been linked to several conditions. Recent studies have demonstrated a change in thinking regarding the human immunodeficiency virus (HIV) and development of PCT. The exacerbation of PCT with contraction of HIV is now believed to result from coinfection from the hepatitis C virus (HCV). Blistering of sun-exposed skin, a classic presenting sign of PCT, is not exclusive to the condition...

BACKGROUND: Anastomotic leakage is a feared complication following colorectal surgery. Early prediction results in improved clinical outcome, but accurate predictive factors remain elusive. Many biomarkers have been studied with respect to diagnosis of anastomotic leakage but the concept of trajectory testing, using biomarkers, has not been assessed with regards to early diagnosis of anastomotic leak. METHODS: C-reactive protein (CRP), procalcitonin (PCT), white cell count (WCC) and gamma-glutamyl transferase were assessed for predictive utility in diagnosing anastomotic leakage with emphasis on identifying an association with change in their levels or trajectory...

BACKGROUND Hypoxic conditions play roles in functioning of human tendon-derived stem cells (hTSCs). The goal of this study was to investigate the effect of various hypoxic conditions in self-renewal capacity and differentiation of TSCs. MATERIAL AND METHODS hTSCs was obtain from supraspinatus tendon donors. Colony formation and cell proliferation assay were used to assess the self-renewal of hTSCs. qRT-PCT and Western blot analysis were used to examine stemness and multi-differentiation potential of hTSCs. RESULTS We found that culturing at 5% O2 is more beneficial for the self-renewal of hTSCs than the other 3 culture conditions, with larger colony size and numbers...

A nanochannel-based electrochemical biosensor has been demonstrated for rapid and multiplexed detection of a panel of three biomarkers associated with rapid detection of sepsis. The label-free biosensor detected procalcitonin (PCT), lipoteichoic acid (LTA), and lipopolysaccharide (LPS) from human whole blood. The biosensor comprises a nanoporous nylon membrane integrated onto a microelectrode sensor platform for nanoconfinement effects. Charge perturbations due to biomarker binding are recorded as impedance changes using electrochemical impedance spectroscopy...

Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of projection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results...

Monoclonal antibody therapies targeting the EGF receptor (EGFR) frequently result in hypomagnesemia in human patients. In contrast, EGFR tyrosine kinase inhibitors do not affect Mg(2+) balance in patients and only have a mild effect on Mg(2+) homeostasis in rodents at elevated doses. EGF has also been shown to affect phosphate (Pi) transport in rat and rabbit proximal convoluted tubules (PCT), but evidence from studies targeting EGFR and looking at Pi excretion in whole animals is still missing. Thus, the role of EGF in regulating reabsorption of Mg(2+) and/or Pi in the kidney remains controversial...

BACKGROUND: Doctors at all levels make prescribing errors which can prolong patients' hospital stay, increase the risk of death, and place a significant financial burden on the health system. Doctors have previously reported receiving little or no feedback on their prescribing errors. The effectiveness of feedback in modifying future practice varies widely, depending on how feedback is delivered. To date there is little evidence about why and how feedback interventions do or do not work...

There is debate surrounding which treatment is superior in overall survival (OS) rates in patients with epidermal growth factor receptor (EGFR) mutant non-small cell lung cancer (NSCLC); first-line tyrosine kinase inhibitor (TKI) followed by second-line platinum-based doublet chemotherapy (PCT), or the reverse sequence. Cross treatment of first- and second-line TKI and PCT makes it difficult to deduce which sequence (TKI-PCT or PCT-TKI) is better for OS. Using the keywords "lung cancer" and "EGFR" we identified clinical trials within the PubMed database which were published between January 2006 and November 2016...

The predictions of two mathematical models of the transmission dynamics of Ascaris lumbricoides and hookworm infection and the impact of mass drug administration (MDA) are compared, using data from India. One model has an age structured partial differential equation (PDE) deterministic framework for the distribution of parasite numbers per host and sexual mating. The second model is an individual-based stochastic model. Baseline data acquired prior to treatment are used to estimate key transmission parameters, and forward projections are made, given the known MDA population coverage...

Procalcitonin (PCT) has been reported as a sensitive marker for neonatal bacterial infections. Recently, small numbers of studies reported usefulness of PCT/C-reactive protein (CRP) ratio in detection of infectious conditions in adults. Thus, we conducted this study to evaluate PCT/CRP ratio in late onset neonatal sepsis. Serum PCT and CRP was measured in blood samples from 7-60 days after birth in 106 of neonates with late onset sepsis and 212 of controls who were matched with gestational age, postnatal age, birth weight and gender...
