RESUMO

BACKGROUND: Beginning their post-licensure clinical practice can be a challenging time for new registered nurses. Pain management is considered an essential responsibility for nurses, requiring pain management that is prompt, safe and effective. Research is needed to examine the experiences of new registered nurses as they adjust to their new role using what they have already learned about pain and pain management. PURPOSE: To examine the lived experiences of new registered nurses, who have been in the role less than a year, as they transition into their registered nurse role as a manager of pain utilizing what they have learned about pain and pain management in the undergraduate program and/or continuing professional development. DESIGN: This research was a phenomenological study in which interviews were audio-recorded and transcribed verbatim. PARTICIPANTS/SETTING: Eight new graduate registered nurses employed less than a year at a 415-bed regional hospital were interviewed. METHODS: Content analysis guidelines were used for the analyses of texts. RESULTS: Themes of navigating relationships, the practice of pain management and disconnect between school and real life were developed from the analyses of texts. CONCLUSIONS: Knowledge generated from this study can be used to better understand the experience of new graduate registered nurses regarding pain management and enhance pain management curricula in undergraduate nursing education and continuing professional development.

RESUMO

Rural communities face barriers to disaster preparedness and considerable risk of disasters. Emergency preparedness among rural communities has improved with funding from federal programs and implementation of a National Incident Management System. The objective of this project was to design and implement disaster exercises to test decision making by rural response partners to improve regional planning, collaboration, and readiness. Six functional exercises were developed and conducted among three rural Nebraska (USA) regions by the Center for Preparedness Education (CPE) at the University of Nebraska Medical Center (Omaha, Nebraska USA). A total of 83 command centers participated. Six functional exercises were designed to test regional response and command-level decision making, and each 3-hour exercise was followed by a 3-hour regional after action conference. Participant feedback, single agency debriefing feedback, and regional After Action Reports were analyzed. Functional exercises were able to test command-level decision making and operations at multiple agencies simultaneously with limited funding. Observations included emergency management jurisdiction barriers to utilization of unified command and establishment of joint information centers, limited utilization of documentation necessary for reimbursement, and the need to develop coordinated public messaging. Functional exercises are a key tool for testing command-level decision making and response at a higher level than what is typically achieved in tabletop or short, full-scale exercises. Functional exercises enable evaluation of command staff, identification of areas for improvement, and advancing regional collaboration among diverse response partners.

RESUMO

Intestinal epithelial lipid rafts contain ganglioside GM1 that is the receptor for cholera toxin (CT). The ganglioside binds CT at the plasma membrane (PM) and carries the toxin through the trans-Golgi network (TGN) to the endoplasmic reticulum (ER). In the ER, a portion of the toxin unfolds and translocates to the cytosol to activate adenylyl cyclase. Activation of the cyclase leads to an increase in intracellular cAMP, which results in apical chloride secretion. Here, we find that an intact actin cytoskeleton is necessary for the efficient transport of CT to the Golgi and for subsequent activation of adenylyl cyclase. CT bound to GM1 on the cell membrane fractionates with a heterogeneous population of lipid rafts, a portion of which is enriched in actin and other cytoskeletal proteins. In this actin-rich fraction of lipid rafts, CT and actin colocalize on the same membrane microdomains, suggesting a possible functional association. Depolymerization or stabilization of actin filaments interferes with transport of CT from the PM to the Golgi and reduces the levels of cAMP generated in the cytosol. Depletion of membrane cholesterol, which also inhibits CT trafficking to the TGN, causes displacement of actin from the lipid rafts while CT remains stably raft associated. On the basis of these observations, we propose that the CT-GM1 complex is associated with the actin cytoskeleton via the lipid rafts and that the actin cytoskeleton plays a role in trafficking of CT from the PM to the Golgi/ER and the subsequent activation of adenylyl cyclase.

RESUMO

Cholera toxin (CT) travels from the plasma membrane of intestinal cells to the endoplasmic reticulum (ER) where a portion of the A-subunit, the A1 chain, crosses the membrane into the cytosol to cause disease. A related toxin, LTIIb, binds to intestinal cells but does not cause toxicity. Here, we show that the B-subunit of CT serves as a carrier for the A-subunit to the ER where disassembly occurs. The B-subunit binds to gangliosides in lipid rafts and travels with the ganglioside to the ER. In many cells, LTIIb follows a similar pathway, but in human intestinal cells it binds to a ganglioside that fails to associate with lipid rafts and it is sorted away from the retrograde pathway to the ER. Our results explain why LTIIb does not cause disease in humans and suggest that gangliosides with high affinity for lipid rafts may provide a general vehicle for the transport of toxins to the ER.
