Bed Rest Reduction Following Cardiac Catheterizations Using Vascular Closure Devices.

Background: Bed rest duration following deployment of a vascular closure device after transfemoral left-sided cardiac catheterization is not standardized. Despite research supporting reduced bed rest, many hospitals require prolonged bed rest. Delayed ambulation is associated with back pain, urine retention, difficulty eating, and longer stay.

The development of commitment: Attention for intention.

Adhering to a partially defined plan requires an intentional commitment that curbs distracting desires conflicting with the planned course of action, enabling humans to act coherently over time. Two studies (N = 50, 27 girls, ages 5-6, Han Chinese, in Hangzhou, China, 2022.02-2022.

Optimal Hemostatic Band Duration After Transradial Angiography or Intervention: Insights From a Mixed Treatment Comparison Meta-Analysis of Randomized Trials.

Background: The optimal duration of hemostatic compression post transradial access is controversial. Longer duration increases the risk of radial artery occlusion (RAO) while shorter duration increases the risk of access site bleeding or hematoma. As such, a target of 2 hours is typically used.

Poison frog dietary preference depends on prey type and alkaloid load.

The ability to acquire chemical defenses through the diet has evolved across several major taxa. Chemically defended organisms may need to balance chemical defense acquisition and nutritional quality of prey items. However, these dietary preferences and potential trade-offs are rarely considered in the framework of diet-derived defenses.

Mechanisms of Convergent Egg Provisioning in Poison Frogs.

Parental provisioning of offspring with physiological products (nursing) occurs in many animals, yet little is known about the neuroendocrine basis of nursing in non-mammalian species. Within amphibians, maternal provisioning has evolved multiple times, with mothers of some species feeding unfertilized eggs to their developing offspring until tadpoles complete metamorphosis [1-3]. We conducted field studies in Ecuador and Madagascar to ask whether convergence at the behavioral level provides similar benefits to offspring and relies on shared neural mechanisms in dendrobatid and mantellid poison frogs.
