We describe nNPipe for the automated analysis of morphologically diverse catalyst materials. Automated imaging routines anddirect-electron detectors have enabled the collection of large data stacks over a wide range of sample positions at high temporalresolution. Simultaneously, traditional image analysis approaches are slow and hence unsuitable for large data stacks andconsequently, researchers have progressively turned towards machine learning and deep learning approaches. Previous studiesoften detail work on morphologically uniform material systems with clearly discernible features, limited workable image sizes andtraining data that may be biased due to manual labelling. The nNPipe data-processing method consists of two standaloneconvolutional neural networks that were exclusively trained on multislice image simulations and enables fast analysis of2048 × 2048 pixel images. Inference performance compared between idealised and real industrial catalytic samples and insightsderived from subsequent data analysis are placed into the context of an automated imaging scenario.

Cyclophosphamide is a potent cytotoxic agent used in many clinical settings. The main risks of cyclophosphamide therapy include hematological disorders, infertility, hemorrhagic cystitis and malignancies. Gastrointestinal side effects reported to date are often non-specific and not severe. We present the first case of a fatal small bowel enteritis and pan-colitis which appears to be associated with cyclophosphamide. We aim to raise the readers' awareness of this significant adverse event to facilitate clinical suspicion and early recognition in potential future cases.
