A brief harvesting-freezing delay significantly alters the kidney metabolome and leads to false positive and negative results.

Abnormalities in distinct metabolic pathways have been associated with the pathogenesis and progression of many forms of kidney disease. Metabolomics analyses can be used to determine organ-specific metabolic fingerprints and, ideally, should represent the metabolic state of the organ at the exact moment the sample is harvested. However, conventional harvesting methods depend on posteuthanasia tissue harvest, which results in ischemia conditions and metabolome changes that could potentially introduce artifacts into the final studies.

Robotic Ultrasound and Novel Collagen Analyses for Polycystic Kidney Disease Research Using Mice.

Key Points: Robotic ultrasound performed favorably compared with magnetic resonance imaging for evaluating total kidney volume. Collagen evaluation by two novel methods of picrosirius red imaging were more informative than the standard method by brightfield imaging. Findings can improve research by increasing speed and access to total kidney volume determination and sensitivity of collagen assessment.

A pilot study evaluating stress factors during and after the COVID-19 pandemic in Viennese families who have the suspicion of child maltreatment or abuse.

The global population was affected by the unprecedented coronavirus COVID-19 pandemic. The impact of the pandemic on children who suffer child maltreatment has not been explored sufficiently. Child abuse is known to increase in stressful circumstances, and therefore potentially during this pandemic.
