This paper describes an LC-MS/MS method to determine the concentration of spironolactone and its metabolites 7-alpha-methylthiospironolactone and canrenone in blood plasma samples. The resulting assay is simple (using protein precipitation for sample preparation) and sensitive (the lower limit of quantification is close to 0.5 ng/ml) while requiring only 50 μl of plasma, making it especially su...

Carboplatin is widely used in pediatric oncology to treat different tumors. Aim of the present study was to assess the potential of sector field inductively coupled plasma mass spectrometry (SF-ICPMS) in evaluating the area under the plasma platinum concentration vs time curve in pediatric patients presenting solid tumors and treated with carboplatin 349-1000 mg m-2. Seventeen patients were enr...

Let X be a (quasi-projective) variety over k. We follow [Sha13, Chap. 6, §1.2].

This study aimed to determine valid waist circumference (WC) thresholds using receiver operating characteristic (ROC) curves for pediatric metabolic syndrome (MS) prediction and to compare validities between the thresholds derived from ROC curves and the WC cut-offs defined by International Diabetes Federation (IDF). Four hundred and sixty four males and 415 females, 10-18 years, who participat...

BACKGROUND Pediatric multiple sclerosis (MS) is a rare disorder with significant consequences. Quantitative MRI measurements may provide significant insights, however multicenter collaborative studies are needed given the small numbers of subjects. The goal of this study is to demonstrate feasibility and evaluate lesion volume (LV) characteristics in a multicenter cohort of children with MS. ...

The new year is a time for goal setting, reflection, and new beginnings. Often, resolutions begin with self-improvements of the physical kind-losing weight, exercising, eating clean. These are important ideas and goals, although often difficult to sustain in part because sustaining is an implied element of each. Intentions are different than goals in the sense that an intention can be implement...

BACKGROUND As childhood obesity increases in the U.S., the Metabolic Syndrome (MS) can be assumed to be increasing in the pediatric population as well. To date, there is lack of information on the most prevalent risk factors of MS in children and the patterns of risk factors present in children met the criteria for MS. METHODS Anthropometric and medical data of children 2-18 years old of a na...
