Host-microbe multiomic profiling identifies distinct COVID-19 immune dysregulation in solid organ transplant recipients.

Coronavirus disease 2019 (COVID-19) poses significant risks for solid organ transplant recipients, who have atypical but poorly characterized immune responses to infection. We aim to understand the host immunologic and microbial features of COVID-19 in transplant recipients by leveraging a prospective multicenter cohort of 86 transplant recipients age- and sex-matched with 172 non-transplant controls. We find that transplant recipients have higher nasal SARS-CoV-2 viral abundance and impaired viral clearance, and lower anti-spike IgG levels.

Volume of intraoperative normal saline versus lactated Ringer's solution on acute kidney injury: A secondary analysis of the SOLAR trial.

Unlabelled: Postoperative acute kidney injury (AKI) is common after non-cardiac surgery. Normal saline and lactated Ringer's solution are both used for volume replacement during surgery. Normal saline decreases renal blood flow and causes hyperchloremic acidosis whereas lactated Ringer's does not.

Biochemical and structural characterization of Rab3GAP reveals insights into Rab18 nucleotide exchange activity.

The heterodimeric Rab3GAP complex is a guanine nucleotide exchange factor (GEF) for the Rab18 GTPase that regulates lipid droplet metabolism, ER-to-Golgi trafficking, secretion, and autophagy. Why both subunits of Rab3GAP are required for Rab18 GEF activity and the molecular basis of how Rab3GAP engages and activates its cognate substrate are unknown. Here we show that human Rab3GAP is conformationally flexible and potentially autoinhibited by the C-terminal domain of its Rab3GAP2 subunit.

Long-Term Trajectories of Older Adults Served by an Emergency Department/Hospital-Based Elder Mistreatment Response Program.

Background: An emergency department (ED) visit or hospitalization provides an opportunity to identify elder mistreatment and initiate intervention, but this seldom occurs. To address this, we developed the Vulnerable Elder Protection Team (VEPT), a novel interdisciplinary consultation service. We explored the long-term trajectories of patients receiving VEPT evaluation and intervention.

The Ontogeny of Attitudes Toward Migrants.

Immigration is among the most pressing issues of our time. Important questions concern the psychological mechanisms that contribute to attitudes about immigration. Whereas much is known about adults' immigration attitudes, the developmental antecedents of these attitudes are not well understood.
