Descending Necrotizing Mediastinitis by Streptococcus anginosus and Prevotella buccae in an Intensive Care Unit Patient: A Case Report.

Necrotizing infections of deep neck spaces are a group of life-threatening infectious diseases acquired through trauma or as a descending infection from an odontogenic source. The isolation of pathogens is unusual because of the anaerobic nature of the infection; however, one way to achieve this is through the use of automated microbiological methods like matrix-assisted laser desorption/ionization and time-of-flight (MALDI-TOF) following standard microbiology protocols for analyzing samples from potential anaerobic infections. We present a case of a patient without risk factors for descending necrotizing mediastinitis with isolation of Streptococcus anginosus and Prevotella​​​​​​​ buccae managed at the intensive care unit with a multidisciplinary team. We present our approach and how we successfully treat this complicated infection.

Becoming Self-Aware of Feelings and Performance: The Influence of Creative Potential, Self-Evaluations, and Metacognitive Feelings on Creative Mindsets.

Based on a recently developed model of creative cognition, we tested in two studies, the relationships between creative potential, self-evaluations, metacognitive feelings, and growth and fixed mindsets in creative action. In both studies, participants (N = 491, mean = 21.57, SD = 2.78 and N = 280, 94% between the ages of 18 and 25 years, respectively, for studies 1 and 2) first completed a divergent thinking task, followed by an assessment of metacognitive feelings, self-evaluations of the creativity of the ideas generated (only in study 2), and creative mindsets while knowing that a second divergent thinking task was coming. Results showed that creative mindsets were sensitive to variations in creative potential, self-evaluations, and metacognitive feelings when examined in creative action. Specifically, studies 1 and 2 showed positive relationships between metacognitive feelings and growth mindsets. Results from study 2 showed positive relationships between self-evaluations of the idea generated and growth mindsets. For fixed mindsets, the creative potential of task 1 had a negative relationship in study 1 and a negative relationship between fixed mindsets and the creative potential of task 2 in study 2. The implications for creative metacognition were explored.
