BACKGROUND The aim of this study was to evaluate factors influencing the 99th percentile for cardiac troponin I (cTnI) when this cutoff value is established on a highly sensitive assay, and to compare the value of this cutoff to that of lower cutoffs in the prognostic assessment of patients with coronary artery disease. METHODS We used the recently refined Access AccuTnI assay (Beckman-Coulte...

OBJECTIVE The aim of this study was to define body fat percentiles for German children and adolescents aged 3-16 years using the largest German database. METHODS The study population included 11,632 girls and 11,604 boys. Data were pooled from: i) Kiel Obesity Prevention Study (KOPS), acquisition period: 1996-2008, n = 12,237; ii) 'Better diet. More exercise. KINDERLEICHT-REGIONS', acquisitio...

In 2012, the Centers for Disease Control and Prevention (CDC) adopted its Advisory Committee on Childhood Lead Poisoning Prevention recommendation to use a population-based reference value to identify children and environments associated with lead hazards. The current reference value of 5 μg/dL is calculated as the 97.5th percentile of the distribution of blood lead levels (BLLs) in children 1 ...

Distributions of 62.4GHz wideband propagation measurements undertaken in two different indoor radio channels to measure spaced-frequency correlation functions are presented. The 90th percentile of the coherence bandwidth at 0.9 correlation level of for all locations values stays below 72MHz. Minimum and maximum B0.9 coherence bandwidths obtained in a long narrow corridor with a directional horn...

OBJECTIVES To examine the distribution of total prostate-specific antigen (tPSA) and percentage of free/total PSA (%f/tPSA) values in patients undergoing prostate cancer screening in Canada. METHODS The data from 4 consecutive annual prostate cancer screening events held in Montreal, Canada were examined with respect to age, tPSA, and %f/tPSA in 3222 men. RESULTS Within the entire cohort, t...

In the 1970s, childhood, and particularly the part of childhood before adolescence, was considered a low–cardiovascular risk state. With the exception of specific conditions such as diabetes mellitus type 1, familial hypercholesterolemia, end stage renal disease, and secondary hypertension, assessment of cardiovascular risk in children seemed unnecessary. Childhood risk factor distributions wer...

www.aafp.org/afp Volume 86, Number 1 ◆ July 1, 2012 Clinical Scenario You have just completed the well-child examination of an eight-year-old boy with a body mass index (BMI) of 18.6 kg per m2 (90th percentile for age and sex). His parents recognize that he is overweight. You provide individual counseling in the office about optimal nutrition, increasing physical activity, and limiting screen t...

. Median weight z-score for children on dialysis was 0.96 whereas children with a functioning transplant had normal weights (median z-score 0). . Median height z-score for children on dialysis was 1.80 and for children with a functioning transplant 1.26. . 79% of transplant patients, 71% of haemodialysis patients and 74% of peritoneal dialysis patients had a systolic blood pressure within the 9...

In 15 consecutive patients with slipped capital femoral epiphysis we recorded height, weight and skeletal maturity. Sexual maturity was assessed clinically and biochemically, and Harris's hypothesis that there is an increased ratio of serum growth hormone to oestrogen was tested in comparison with 15 age and sex matched controls. We found no difference in skeletal or sexual maturity between the...

Ultrawideband (UWB) attracts extensive attention for the Internet-of-Things applications, especially fine-grained location-based services. Rather than active tracking, this article explores UWB-based device-free pedestrian tracking problem. Concerning challenges of passive low-cost commodity UWB devices, we propose a variance-based temporary-spatial (VATS) mapping algorithm, which relieves back...
