This study examined the interactions between Daphnia magna and a water-soluble, lysophophatidylcholine coated single-walled carbon nanotube. D. magna were able to ingest the nanotubes through normal feeding behavior and utilize the lysophophatidylcholine coating as a food source. D. magna were able to modify the solubility of the nanotube, likely through digestion of the lipid coating. This study provides evidence of biomodification of a carbon-based nanomaterial by an aquatic organism. The modification significantly altered the physical properties of the nanomaterial in freshwater. Acute toxicity was observed only in the highest test concentrations. These are important findings related to determining the behavior and potential toxicity of coated nanomaterials released into the environment.

Engagement may provide the foundation for safe, therapeutic, and recovery-oriented treatment. In the future, APNA's ISE plans to build upon this foundation by developing a clinical model of nurse-patient engagement and safety by drawing together emerging research and practice models.

Elimination of seclusion and restraint requires support at all levels of an organization, especially from leaders who visibly champion and communicate their vision. Nurses, physicians, educators, and administrators at New Hampshire Hospital, an acute psychiatric inpatient facility, have established a standard meeting time and place for an executive-level review of every episode of seclusion and restraint. The standing meeting demonstrates the organization's commitment to caring for both patients and staff. The daily meetings foster a spirit of interdisciplinary collaboration, where direct care staff have the opportunity to tell their stories and share their ideas and concerns in an environment that is caring, supportive, and devoid of criticism or blame. Narrative descriptions of emergency interventions, including what was learned from debriefings with patients and staff involved, provide data about factors that may contribute to the use of seclusion or restraint. This forum provides visible administrative and clinical support that promotes creative thinking, collaborative problem solving, and the exploration of new ideas recommended by those directly involved in providing patient care. It has fostered exploration and development of strategies that have minimized episodes of aggressive behavior as well as seclusion and restraint.
