Perceptions of Frailty and Prehabilitation Among Thoracic Surgeons: Findings From a National Survey.

Background: Frailty is associated with increased perioperative morbidity and mortality. How thoracic surgeons recognize, measure, and mitigate frailty in their daily clinical practice is unknown. We administered a national survey to determine the current practices of thoracic surgeons managing frail patients.

Assessment of printed lung cancer surgery patient education materials in the United States.

Objective: Well-designed patient education materials (PEMs) increase health literacy, which has been linked to better surgical patient outcomes. The quality of lung cancer surgery PEMs is unknown, however. Here we assessed printed lung cancer surgery PEMs for readability, understandability, actionability, and accessibility.

Differences in gene expression between high and low tolerance rainbow trout (Oncorhynchus mykiss) to acute thermal stress.

Understanding the mechanisms that underlie the adaptive response of ectotherms to rising temperatures is key to mitigate the effects of climate change. We assessed the molecular and physiological processes that differentiate between rainbow trout (Oncorhynchus mykiss) with high and low tolerance to acute thermal stress. To achieve our goal, we used a critical thermal maximum trial in two strains of rainbow trout to elicit loss of equilibrium responses to identify high and low tolerance fish.

Complex and Dynamic Gene-by-Age and Gene-by-Environment Interactions Underlie Functional Morphological Variation in Adaptive Divergence in Arctic Charr (Salvelinus alpinus).

The evolution of adaptive phenotypic divergence requires heritable genetic variation. However, it is underappreciated that trait heritability is molded by developmental processes interacting with the environment. We hypothesized that the genetic architecture of divergent functional traits was dependent on age and foraging environment.
