Postprandial exercise attenuates glucose and insulin and is associated with age, cognitive function, and extracellular/intracellular body water Open
Postprandial exercise attenuates glucose/insulin and is recommended for people with metabolic disease. The magnitude of the attenuation has not been directly compared in healthy older and younger people, who are active exercisers, or corre…

Longterm Neuroendocrine and Metabolic Effects of Physical Training in Intermittent Claudication Open
Twenty-five elderly patients with peripheral vascular disease and intermittent claudication were prospectively followed during a six-month session of physical training. Neuroendocrine and metabolic patterns as well as effects on walking pe…

Measurement repeatability profiles of eight frequently requested measurands in clinical chemistry determined by duplicate measurements of patient samples Open
Measurement uncertainties in clinical chemistry are commonly regarded as heteroscedastic - having a constant relative standard deviation irrespective of the concentration of the measurand. The uncertainty is usually determined at two conce…

Repeatability imprecision from analysis of duplicates of patient samples and control materials Open
Measurement imprecision is usually calculated from measurement results of the same stabilized control material(s) obtained over time, and is therefore, principally, only valid at the concentration(s) of the selected control material(s). Th…

An experimental study of methods for the analysis of variance components in the inference of laboratory information Open
Measurement uncertainty (MU) can be estimated and calculated by different procedures, representing different aspects and intended use. It is appropriate to distinguish between uncertainty determined under repeatability and reproducibility …

Impact of Glucose Measuring Systems and Sample Type on Diagnosis Rates of Diabetes Mellitus Open
Venous blood samples measured at the point-of-care are the most suitable sample type for the measurement of the glucose concentration in the 2-h OGTT. The investigated unit-use POCT method is suitable for the diagnosis of IGT and DM when v…

Bayes’ theorem, the ROC diagram and reference values: Definition and use in clinical diagnosis Open
Medicine is diagnosis, treatment and care. To diagnose is to consider the probability of the cause of discomfort experienced by the patient. The physician may face many options and all decisions are liable to uncertainty to some extent. Th…

Validation of an enzyme-linked immunosorbent assay for the quantification of citrullinated histone H3 as a marker for neutrophil extracellular traps in human plasma Open
There is an emerging interest in the diverse functions of neutrophil extracellular traps (NETs) in a variety of disease settings. However, data on circulating NETs rely largely upon surrogate NET markers such as cell-free DNA, nucleosomes,…

Analytical robustness of nine common assays: frequency of outliers and extreme differences identified by a large number of duplicate measurements Open
Duplicate measurements of a large number of patient samples identify even low frequencies of extreme differences and thereof defined outliers. We suggest two additional quality markers, AZ95 and OPM, to complement description of assay perf…

Further on creating normal density functions in Microsoft® Excel Open
Simulations play an increasing role in metrology and analytical chemistry, particularly the use of simulated normal distributions. Microsoft Excel is available to almost everybody and normal distributions can be simulated using either an i…

Discrepant post filter ionized calcium concentrations by common blood gas analyzers in CRRT using regional citrate anticoagulation Open
Introduction Ionized calcium (iCa) concentration is often used in critical care and measured using blood gas analyzers at the point of care. Controlling and adjusting regional citrate anticoagulation (RCA) for continuous renal replacement …
