A Review of Trauma-Informed Care for Youth and Their Families in Inpatient Pediatric Settings.

Due to the pervasiveness of trauma, it is likely that many children and families seen in pediatric health settings have incurred traumatic experiences. These experiences can lead to a variety of negative medical, psychological, and social health outcomes. Therefore, a provider's focus on supporting resilience is integral. The use of trauma-informed care (TIC) is one way providers can work toward promoting a family's resilience. TIC is considered an organizational, attitudinal shift to understanding the broad impacts of trauma. This shift can contribute to changes in policies and procedures to make each system more welcoming to all those accessing the health system. This review will discuss the current pervasiveness of trauma, its associated impacts, the importance of TIC, and practical applications of TIC based on guiding principles provided by the Substance Abuse and Mental Health Services Administration.

Mechanisms and consequences of flight polyphenisms in an outbreaking bark beetle species.

Flight polyphenisms naturally occur as discrete or continuous traits in insects. Discrete flight polyphenisms include winged and wingless morphs, whereas continuous flight polyphenisms can take the form of short- or long-distance fliers. The mountain pine beetle (Dendroctonus ponderosae) exhibits polyphenic variation in flight distance but the consequences of this flight variation on life history strategies of beetles is unknown. This study assessed the effect of flight on two particular aspects of beetle biology: (1) an energetic trade-off between flight distance and host colonisation capacity; and (2) the relationship between flight distance and pheromone production. A 23 h flight treatment was applied to a subset of beetles using computer-linked flight mills. After flight treatment, both flown and unflown (control) beetles were given the opportunity to colonise bolts of host trees, and beetles that entered hosts were aerated to collect pheromone. A trade-off occurred between initiation of host colonisation and percentage body mass lost during flight, which indicates energy use during flight affects host acceptance in female mountain pine beetles. Furthermore, production of the aggregation pheromone trans-verbenol by female beetles was influenced by both percentage body mass lost during flight and flight distance. Male production of exo-brevicomin was affected by beetle condition following flight but not by the energy used during flight. These novel results give new insight into the polyphenic flight behaviour of mountain pine beetles. Flight variation is adaptive by acting to maintain population levels through safe and risky host colonisation strategies. These findings suggest mechanisms that facilitate the extremities of the continuous flight polyphenism spectrum. These opposing mechanisms appear to maintain the high variation in flight exhibited by this species.
