Small bowel cancers are rare, accounting for only about 6000 cases/year in the United States, approximately 25% of which are small bowel adenocarcinomas. Small bowel adenocarcinomas have traditionally been considered to be highly fatal due to their nonspecific presentation at the time of diagnosis, and to the lack of responsiveness to older chemotherapy(More)
BACKGROUND Pediatric healthcare is critically dependent on the availability of accurate and precise laboratory biomarkers of pediatric disease, and on the availability of reference intervals to allow appropriate clinical interpretation. The development and growth of children profoundly influence normal circulating concentrations of biochemical markers and(More)
BACKGROUND: We performed a retrospective population-based study to assess the impact of tyrosine kinase inhibitors (TKIs) on overall survival (OS) in patients treated for metastatic renal cell carcinoma (mRCC) in Alberta, Canada and to assess the impact of nephrectomy on OS in patients treated with TKIs. METHODS: We identified 134 patients who began taking(More)
Leptin, a hormone made by adipocytes, is an important circulating signal for the regulation of body weight. A review of the scientific literature (PubMed Search 1994 to 2005) for studies examining the relationship among leptin, pediatric obesity and the impact of exercise intervention programmes on leptin concentrations are summarized. The potential utility(More)
OBJECTIVE The initial discovery of leptin (1994) has given rise to a substantial number of published studies. This study aimed at identifying the published data on the reference ranges of total, free and bound leptin concentration in the healthy prepubertal population. METHODS A search was conducted on original English language studies published from 1994(More)
OBJECTIVE To investigate the BioPlex 2200 multiplex immunoassay and Farrzyme ELISA assays as alternatives to the established Farr radioimmunoassay for the correlation of anti-dsDNA antibodies in the assessment of disease activity in systemic lupus erythematosus (SLE). DESIGN AND METHODS Standard protocols were used to verify analytical performance claims.(More)
OBJECTIVES Pediatric serum samples collected from healthy children in the CALIPER (Canadian Laboratory Initiative in Pediatric Reference Interval) project are stored at -80 °C for various periods of time. This study aimed to determine the stability of chemistry, protein, and hormone analytes under these conditions. DESIGN AND METHODS Serum samples(More)
OBJECTIVES Fasting samples can be difficult to obtain in the pediatric setting, particularly in neonates. As part of the Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER), we aimed to determine if there are differences in serum concentrations of pediatric biochemical markers measured at fasting, postprandial, and random time points(More)
The Biochemical Evaluation of a Health Intervention Programme (B.E. H.I.P.) investigated the impact of progressive exercise intensity in overweight and obese children. A 5-month prospective randomized crossover design (X(A), immediate intervention; O(B), control group; X(B), delayed intervention, O(A), postintervention follow-up) with a 10-week health(More)
Low rates of cardiovascular preventive therapy with statin medications is a significant public health problem in Canada. There is a pressing need for public health interventions to increase the use of statin medications, especially among high-risk patients. In this article, we present the results of a quality assurance pilot program to provide(More)
