Novel Drop-Sampler for Simultaneous Collection of Stereo-Video, Environmental DNA and Oceanographic Data.

There is an increasing interest in environmental DNA (eDNA) as a method to survey marine biota, enhancing traditional survey methods, and a need to ground truth eDNA-based interpretations with visual surveys to understand biases in both the eDNA and visual datasets. We designed and tested a rapidly deployable, robust method pairing water sampling for eDNA collection and stereo-video imagery, comparing inferred fish assemblages with interspersed baited remote underwater video (stereo-BRUV) samples. The system is capable of rapidly collecting simultaneous wide-field stereo-video imagery, oceanographic measurements and multiple water samples across a range of habitats and depths (up to 600 m).

Plasticity of Human Microglia and Brain Perivascular Macrophages in Aging and Alzheimer's Disease.

The complex roles of myeloid cells, including microglia and perivascular macrophages, are central to the neurobiology of Alzheimer's disease (AD), yet they remain incompletely understood. Here, we profiled 832,505 human myeloid cells from the prefrontal cortex of 1,607 unique donors covering the human lifespan and varying degrees of AD neuropathology. We delineated 13 transcriptionally distinct myeloid subtypes organized into 6 subclasses and identified AD-associated adaptive changes in myeloid cells over aging and disease progression.

a grounded theory study of nonbinary peoples' internal processes for navigating binary gender norms.

Nonbinary people experience marginalization through discrimination, rejection, microaggressions, and stigma as a result of not always conforming to societal gender norms embedded in the gender binary. There is limited research about how nonbinary Black, Indigenous, and People of Color (BIPOC) living in the United States navigate societally enforced binary gender norms, which is especially important to understand given how racism and Euro-colonization have enforced the gender binary. Better understanding the internal strategies nonbinary people use to cope, embody affirmation, and regulate emotions in response to marginalizing experiences could increase understanding of how to best prevent and address the health disparities experienced by nonbinary people.

Effect of correcting iron deficiency on the risk of serious infection in heart failure: Insights from the IRONMAN trial.

Aims: Concerns exist that intravenous (IV) iron might increase the risk of infections. The IRONMAN trial provided an opportunity to investigate whether giving IV ferric derisomaltose (FDI) to patients with heart failure and iron deficiency alters the rate of hospitalization or death due to infections.

Methods And Results: IRONMAN was a randomized trial of IV FDI versus usual care in patients with symptomatic heart failure, left ventricular ejection fraction (LVEF) ≤45%, and transferrin saturation (TSAT) <20% or ferritin <100 μg/L.
