The small molecular metabolite analytes were detected from the dried blood spot (DBS) samples by MS/MS. Genetic analysis of 68 Chinese MMA cases were performed by whole-exome sequencing and Sanger sequencing. Random forest classifiers (RFC) were constructed to improve the MMA screening performance and genotype prediction in two Chinese populations.

A rapid screening classifier for diagnosing COVID-19
A classifier combining chest X-ray (CXR) with clinical features may serve as a rapid screening approach. Methods: The study included 512 patients with COVID-19 and 106 with influenza A/B pneumonia. A deep neural network (DNN) was applied, and deep features derived from CXR and clinical findings formed fused features for diagnosis prediction.
