Effective infectious disease surveillance in high-risk regions is critical for clinical care and pandemic preemption; however, few clinical diagnostics are available for the wide range of potential human pathogens. Here, we conduct unbiased metagenomic sequencing of 593 samples from febrile Nigerian patients collected in three settings: i) population-level surveillance of individuals presenting with symptoms consistent with Lassa Fever (LF); ii) real-time investigations of outbreaks with suspected infectious etiologies; and iii) undiagnosed clinically challenging cases. We identify 13 distinct viruses, including the second and third documented cases of human blood-associated dicistrovirus, and a highly divergent, unclassified dicistrovirus that we name human blood-associated dicistrovirus 2. We show that pegivirus C is a common co-infection in individuals with LF and is associated with lower Lassa viral loads and favorable outcomes. We help uncover the causes of three outbreaks as yellow fever virus, monkeypox virus, and a noninfectious cause, the latter ultimately determined to be pesticide poisoning. We demonstrate that a local, Nigerian-driven metagenomics response to complex public health scenarios generates accurate, real-time differential diagnoses, yielding insights that inform policy.

The unexpected rise in cancer and diabetes statistics has been a significant global threat, inciting ongoing research into various biomarkers that can act as innovative therapeutic targets for their management. The recent discovery of how EZH2-PPARs' regulatory function affects the metabolic and signalling pathways contributing to this disease has posed a significant breakthrough, with the synergistic combination of inhibitors like GSK-126 and bezafibrate for treating these diseases. Nonetheless, no findings on other protein biomarkers involved in the associated side effects have been reported. As a result of this virtual study, we identified the gene-disease association, protein interaction networks between EZH2-PPARs and other protein biomarkers regulating pancreatic cancer and diabetes pathology, ADME/Toxicity profiling, docking simulation and density functional theory of some natural products. The results indicated a correlation between obesity and hypertensive disease for the investigated biomarkers. At the same time, the predicted protein network validates the link to cancer and diabetes, and nine natural products were screened to have versatile binding capacity against the targets. Among all natural products, phytocassane A outperforms the standard drugs' (GSK-126 and bezafibrate) in silico validation for drug-likeness profiles. Hence, these natural products were conclusively proposed for additional experimental screening to complement the results on their utility in drug development for diabetes and cancer therapy against the EZH2-PPARs' new target.
