Body Composition Assessment in Critically Ill Adults - Where are We now?

This narrative review provides an overview of body composition methods available for use in critically ill patients. It focuses on the relevance and discussion of the most commonly used techniques. Further, we discuss the validity of these methods with a focus on muscle mass assessment, measuring changes over time and the identification of patients with lower-than-normal muscularity.

Privacy in Networks of Quantum Sensors.

We treat privacy in a network of quantum sensors where accessible information is limited to specific functions of the network parameters, and all other information remains private. We develop an analysis of privacy in terms of a manipulation of the quantum Fisher information matrix, and find the optimal state achieving maximum privacy in the estimation of linear combination of the unknown parameters in a network of quantum sensors. We also discuss the effect of uncorrelated noise on the privacy of the network.

David couldn't bring down Goliath: museum specimen reveals a failed predation attempt by fire ants ( Westwood, 1840) upon a large hawk moth (Cramer, 1775).

Insights into insect predatory behaviour can be inferred indirectly from specimens housed in Natural History Collections. In this work, we document a unique interaction, never recorded before, involving the remains of a Westwood, 1840 ant worker -probably (Smith, 1855)- whose head is firmly attached by its mandibles to an antenna of a female hawk moth (Cramer, 1775) (Sphingidae). This specimen is part of the Entomology Collection at the MNCN-CSIC in Madrid, Spain.

Multi-omics profiling reveals altered mitochondrial metabolism in adipose tissue from patients with metabolic dysfunction-associated steatohepatitis.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form steatohepatitis (MASH) contribute to rising morbidity and mortality rates. The storage of fat in humans is closely associated with these diseases' progression. Thus, adipose tissue metabolic homeostasis could be key in both the onset and progression of MASH.

Antiracist activism for immigrant rights and healthy coping: Initial evidence for a community-based framework.

Racist and xenophobic policies in the United States (e.g., family separations and lack of access to protected immigration statuses for undocumented immigrants) have historically excluded immigrants of color from accessing full civil rights, thus contributing to widening racial inequities in the US.
