Patients undergoing peripheral venoarterial extracorporeal membrane oxygenation have a high risk of lower limb ischemia. In general, regular controls are carried out based on clinical and laboratory parameters in order to quickly detect and treat complications. ⋯ As additional monitoring the use of near-infrared spectroscopy (NIRS) is described in the literature as being very successful in detecting ischemia. The present article describes the use and possible limitations of NIRS for the diagnostics of peripheral ischemia.

In naturally occurring numbers the frequencies of digits 1-9 in the leading position are counterintuitively distributed because the frequencies of occurrence are unequal. Benford-Newcomb's law describes the expected distribution of these frequencies. It was previously shown that known fraudulent articles consistently violated this law. ⋯ All 12 of the known falsified articles violated Benford-Newcomb's law, which indicated that this analysis had a high sensitivity. The low specificity of the assessment may be explained by the assumptions made about the articles identified for comparison. Violations of Benford-Newcomb's law about the frequencies of the leading digits cannot serve as proof of falsification but they may provide a basis for deeper discussions between the editor and author about a submitted work.
