A novel herpesvirus in blue penguins putatively associated with myocardial degeneration and necrosis.

We identified a novel herpesvirus in 2 deceased captive blue penguins (). Moderate-to-severe myocardiocyte atrophy and necrosis, and eosinophilic intranuclear inclusion bodies (INIBs), were seen in myocardiocytes in one bird; reticuloendothelial (RE) cell INIBs and multifocal RE cell necrosis were seen in both birds. The histologic findings were suggestive of viral infection.

Are Ratings of Perceived Exertion during Endurance Tasks of Predictive Value? Findings in Trunk Muscles Require Special Attention.

: Subjective rating scales of perceived exertion are often used to quantify effort levels during various endurance exercises, particularly submaximal tasks. The aim of the current study was to determine whether predictive conclusions can be drawn from perceived exertion levels surveyed at the start of defined submaximal endurance tasks. : In this study, healthy participants performed a 10-min endurance task at 50% of their upper body weight, targeting either the back muscles (n = 47, 24 women) or abdominal muscles (n = 32, 17 women).

Neuropsychological and Health Literacy Correlates of Science Knowledge Among Older and Younger Healthy Adults.

Science knowledge refers to the depth and breadth of facts acquired within the life, social, and earth sciences, and it has implications for both public and personal health. Drawing from cognitive aging theory, we examine whether levels of science knowledge are associated with age, neuropsychological functioning, and personal health literacy. Fifty-two younger and fifty older healthy adults completed our telephone-based study that included a commonly used test of science knowledge, as well as measures of neuropsychological functioning, health literacy, and relevant descriptives (e.

Exploring Medical Student Experiences With Direct Observation During the Pediatric Clerkship.

Purpose: Direct observation (DO) enables assessment of vital competencies, such as clinical skills. Despite national requirement that medical students experience DOs during each clerkship, the frequency, length, quality, and context of these DOs are not well established. This study examines the quality, quantity, and characteristics of DOs obtained during pediatrics clerkships across multiple institutions.
