The development of reliable, mixed-culture biotechnological processes hinges on understanding how microbial ecosystems respond to disturbances. Here we reveal extensive phenotypic plasticity and niche complementarity in oleaginous microbial populations from a biological wastewater treatment plant. We perform meta-omics analyses (metagenomics, metatranscriptomics, metaproteomics and metabolomics) on in situ samples over 14 months at weekly intervals. Based on 1,364 de novo metagenome-assembled genomes, we uncover four distinct fundamental niche types. Throughout the time-series, we observe a major, transient shift in community structure, coinciding with substrate availability changes. Functional omics data reveals extensive variation in gene expression and substrate usage amongst community members. …

Artificial Intelligence For Rapid Meta-Analysis: Case Study On Ocular Toxicity Of Hydroxychloroquine., Matthew Michelson, Tiffany Chow, Neil A Martin, Mike Ross, Amelia Tee Qiao Ying, Steven Minton

Articles, Abstracts, and Reports

BACKGROUND: Rapid access to evidence is crucial in times of an evolving clinical crisis. To that end, we propose a novel approach to answer clinical queries, termed rapid meta-analysis (RMA). Unlike traditional meta-analysis, RMA balances a quick time to production with reasonable data quality assurances, leveraging artificial intelligence (AI) to strike this balance.

OBJECTIVE: We aimed to evaluate whether RMA can generate meaningful clinical insights, but crucially, in a much faster processing time than traditional meta-analysis, using a relevant, real-world example.

METHODS: The development of our RMA approach was motivated by a currently relevant clinical question: is ocular toxicity and …

Randomized Phase Ii Study Of Stereotactic Body Radiotherapy And Interleukin-2 Versus Interleukin-2 In Patients With Metastatic Melanoma., Brendan Curti, Marka R Crittenden, Steven K Seung, Christopher B Fountain, Roxanne Payne, Shuching Chang, Jessica Fleser, Kimberly Phillips, Ian Malkasian, Lyn B Dobrunick, Walter Urba

Articles, Abstracts, and Reports

BACKGROUND: A pilot study of stereotactic body radiation therapy (SBRT) followed by high-dose interleukin-2 (IL-2) showed a higher than anticipated objective response rate (ORR) among patients with metastatic melanoma (MM). We performed a prospective randomized study to determine if the ORR of SBRT + IL-2 was greater than IL-2 monotherapy in patients with advanced melanoma.

METHODS: Patients with MM who had adequate physiological reserve for IL-2 and at least one site suitable for SBRT were eligible. There was a 1:1 randomization to SBRT + IL-2 or IL-2 monotherapy. Patients received one or two doses of SBRT (20 Gy per fraction) …
