Cortical processing of color: Chromatic visual evoked potentials.

Evoked potentials measured from human visual cortex reveal that, in humans as in other primates, color is represented in the cortex mostly by neurons that are spatially-tuned. This means that color perception is most affected by spatial patterns of color and by the color difference across the boundaries of colored regions. The evidence from cortical evoked responses also supports the concept that the cortex does away with the strict segregation of color and luminance signals, and of red-green vs blue-yellow signals, that is present in its thalamic input.

Equalising power imbalances or a trail of broken promises? A qualitative study on engaging people with diverse lived experience of marginalisation in food policymaking in Australia.

Background: Achieving nutrition and health equity warrants understanding lived experiences of marginalisation. Yet, people with diverse lived experiences are often inadequately included in food policy advocacy, agenda setting, and development. We aimed to explore cross-sectoral perceptions of engaging people with lived experiences of marginalisation in food policymaking in Australia, specifically in terms of challenges, enablers, required actions, and potential outcomes of doing so.

Microbiota translocation following intestinal barrier disruption promotes Mincle-mediated training of myeloid progenitors in the bone marrow.

Impairment of the intestinal barrier allows the systemic translocation of commensal bacteria, inducing a proinflammatory state in the host. Here, we investigated innate immune responses following increased gut permeability upon administration of dextran sulfate sodium (DSS) in mice. We found that Enterococcus faecalis translocated to the bone marrow following DSS treatment and induced trained immunity (TI) hallmarks in bone-marrow-derived mouse macrophages and human monocytes.

Underutilization of Influenza Antiviral Treatment Among Children and Adolescents at Higher Risk for Influenza-Associated Complications - United States, 2023-2024.

Annually, tens of thousands of U.S. children and adolescents are hospitalized with seasonal influenza virus infection.

Laboratory-Confirmed Influenza-Associated Hospitalizations Among Children and Adults - Influenza Hospitalization Surveillance Network, United States, 2010-2023.

Problem/condition: Seasonal influenza accounts for 9.3 million-41 million illnesses, 100,000-710,000 hospitalizations, and 4,900-51,000 deaths annually in the United States. Since 2003, the Influenza Hospitalization Surveillance Network (FluSurv-NET) has been conducting population-based surveillance for laboratory-confirmed influenza-associated hospitalizations in the United States, including weekly rate estimations and descriptions of clinical characteristics and outcomes for hospitalized patients.
