With a little help from my friends: importance of protist-protist interactions in structuring marine protistan communities in the San Pedro Channel.

Unlabelled: Marine protists form complex communities that are shaped by environmental and biological ecosystem properties, as well as ecological interactions between organisms. While all of these factors play a role in shaping protistan communities, the specific ways in which these properties and interactions influence protistan communities remain poorly understood. Fourteen years and 9 months of eukaryotic amplicon (18S-V4 rRNA gene) data collected monthly at the San Pedro Ocean Time-series (SPOT) station were used to evaluate the impacts that environmental and biological factors, and protist-protist interactions had on protistan community composition.

Outpatient Palliative Care and End-of-Life Care Intensity: Linking Massachusetts Cancer Registry with All-Payer Claims.

Background: Early palliative care is associated with better outcomes for patients with advanced-stage cancers. Using a novel data linkage, we assessed outpatient palliative care use before death and its association with end-of-life care intensity and variation across eight provider networks.

Methods: We linked Massachusetts Cancer Registry and the All-Payer Claims Database for individuals with commercial insurance, Medicaid or Medicare Advantage diagnosed with colorectal, lung, prostate, and breast cancers from 2010 through 2013 who died by December 31, 2014.

Use of Financial Hardship as a Metric for Assessing Financial Toxicity in Surgical Trauma Patients.

Background: Financial toxicity is the detrimental impact of health care costs that must be mitigated to achieve universal health coverage. Catastrophic health expenditure (CHE) is widely used to measure financial toxicity but does not capture patient perspectives of unaffordable health care costs. Financial hardship (FH), a patient-reported outcome measure, is currently underutilized but may be an important adjunct metric.

Multiplexed mosaic tumor models reveal natural phenotypic variations in drug response within and between populations.

Many agents that show promise in preclinical cancer models lack efficacy in patients due to patient heterogeneity that is not captured in traditional assays. To address this problem, we have developed GENEVA, a platform that measures the molecular and phenotypic consequences of drug perturbations within diverse populations of cancer cells at single-cell resolution, both and . Here, we apply GENEVA to study the KRAS G12C inhibitors, recapitulating known properties of these drugs and uncovering a previously unknown role for mitochondrial activation in cell death induced by KRAS inhibition.

CD47 predominates over CD24 as a macrophage immune checkpoint in cancer.

Macrophages hold tremendous promise as effectors of cancer immunotherapy, but the best strategies to provoke these cells to attack tumors remain unknown. Here, we evaluated the therapeutic potential of targeting two distinct macrophage immune checkpoints: CD47 and CD24. We found that antibodies targeting these antigens could elicit maximal levels of phagocytosis when combined together in vitro.
