INTRODUCTION Components of the systemic inflammatory response, combined to form inflammation-based prognostic scores (modified Glasgow Prognostic Score (mGPS), Neutrophil Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), Prognostic Index (PI), Prognostic Nutritional Index (PNI)) have been associated with cancer specific survival. The aim of the(More)
Individuals with severe, sporadic disorders of infantile onset represent an important class of disease for which discovery of the underlying genetic architecture is not amenable to traditional genetic analysis. Full-genome sequencing of affected individuals and their parents provides a powerful alternative strategy for gene discovery. We performed(More)
PURPOSE The management of epilepsy in children is particularly challenging when seizures are resistant to antiepileptic medications, or undergo many changes in seizure type over time, or have comorbid cognitive, behavioral, or motor deficits. Despite efforts to classify such epilepsies based on clinical and electroencephalographic criteria, many children(More)
BACKGROUND Studies indicate that low plasma 25-hydroxyvitamin D [25(OH)D] is associated with a range of disease processes, many of which are inflammatory. However, other lipid-soluble vitamins decrease during the systemic inflammatory response, and this response may confound the interpretation of plasma 25(OH)D. OBJECTIVE The objective was to examine(More)
AIM To study the endogenous cortisol levels in patients with central serous chorioretinopathy (CSCR). METHODS Endogenous cortisol levels in urine and plasma were determined in 30 patients with acute CSCR and compared with 30 age and sex matched controls. RESULTS The mean values of the 8 am plasma cortisol (29.97 micrograms/dl v 18.76 micrograms/dl), 11(More)
BACKGROUND The plasma concentration of vitamin K(1) (phylloquinone) is the most reliable index for assessing vitamin K status. Our aim was to analytically validate an HPLC method for quantifying phylloquinone in plasma and to examine the effect of plasma triglyceride concentration on the phylloquinone reference interval. We also examined the effect of(More)
The relationship between lipid soluble antioxidant vitamins, lipid peroxidation, disease stage and the systemic inflammatory response were examined in healthy subjects (n = 14), patients with benign prostate hyperplasia BPH (n = 20), localized (n = 40) and metastatic (n = 38) prostate cancer. Prostate cancer patients had higher concentrations of(More)
The level of non-enzymatic glycation of a protein is thought to depend on the number of sites available for reaction, the half-life of the protein and the ambient concentration of glucose. Accordingly, the modification of two blood proteins with a similar number of potential sites but different survival times was examined in non-diabetic patients by(More)
BACKGROUND & AIMS Plasma selenium concentration and glutathione peroxidase (GPx) activity are commonly used as markers of selenium nutritional status. However, plasma selenium concentrations fall independently of selenium status during the acute phase response and GPx is analytically problematic. The assay for erythrocyte selenium is robust and(More)
BACKGROUND AND AIMS The majority of patients with advanced cancer have reduced circulating concentrations of the vitamin antioxidants including retinol, alpha-tocopherol and carotenoids. However, the basis of this reduction is not known. Vitamin antioxidant concentrations have been reported to be correlated with a systemic inflammatory response (as(More)
