Sensitivity of Lung Point-of-Care Ultrasound (POCUS) to Predict Oxygen Requirements in Emerging Viral Infections.

Objectives: The prognostic characteristics of lung point-of-care ultrasound (L-POCUS) to predict respiratory decompensation in patients with emerging infections remains unstudied. Our objective was to examine whether scored lung ultrasounds predict hypoxia among a nonhypoxic, ambulatory population of patients with COVID-19.

Methods: This was a diagnostic case-control study.

The roles of central amygdala D1 and D2 receptors on attentional performance in a five-choice task.

The central amygdala (CeA) has been shown to play an important role in mediating several attentional processes, including selective and sustained attention. Emerging evidence suggests that the connections between the CeA and the midbrain dopamine areas are important for attentional processing. However, little is known about the role of dopaminergic input into the CeA in mediating attentional processes.

Impulsivity, risk-taking, and distractibility in rats exhibiting robust conditioned orienting behaviors.

When a neutral cue is followed by a significant event such as food delivery, some animals become engaged with the cue itself and acquire cue-directed behaviors. One type of cue-directed behavior is observed following insertion of a lever used as a conditioned stimulus (CS). Rats showing robust approach behavior to the lever also display impulsivity and altered attention, as compared to rats showing behavior directed toward the reward delivery location.
