Impacts of Mobile Computing and Communication on Library Instruction
In his latest book, futurist Howard Rheingold defines the smartmob, a new paradigm in social computing in which people ... cooperate in ways never before possible because they carry devices that possess both communication and computing capabilities. The presenters set out to explore the implications of this paradigm for information literacy learning and instruction. They will present the findings of a pilot study conducted to investigate the use of mobile computing and communication technologies by undergraduates at the University of Utah. Technologies explored include handheld wireless devices, mobile audio devices, new cell phone features, and Internet communication software such as blogs, instant messenger, community forums, etc. The findings regarding students\u27 social and school-related uses of these technologies, and the impact our findings have had on developing new models of library instruction will be discussed. Comparison of the findings to national data in order to assess broader implications of the data, analyze local variances, and predict future trends will be shared. The discussion will emphasize the do-able aspects of creating and using mobile communication technologies for library instruction by providing examples from our program and other national efforts in this area. Participants in the session will leave with tips for conducting similar studies at their institutions and with suggestions for ways to stay abreast of how students are using technology in their lives. The conclusion will focus on a discussion of tools of the future and how to anticipate users\u27 needs and ways to connect with them through library instruction

Outcomes Following Concomitant Traumatic Brain Injury and Hemorrhagic Shock: A Secondary Analysis from the PROPPR Trial.
Often the clinician is faced with a diagnostic and therapeutic dilemma in patients with concomitant traumatic brain injury (TBI) and hemorrhagic shock (HS), as rapid deterioration from either can be fatal. Knowledge about outcomes following concomitant TBI and HS may help prioritize the emergent management of these patients. We hypothesized that patients with concomitant TBI and HS (TBI+HS) had worse outcomes and required more intensive care compared to patients with only one of these injuries.This is a post-hoc analysis of the Pragmatic, Randomized Optimal Platelets and Plasma Ratios (PROPPR) trial. TBI was defined by a head abbreviated injury scale >2. HS was defined as a base excess ≤ -4 and/or shock index ≥ 0.9. The primary outcome for this analysis was mortality at 30 days. Logistic regression, using generalized estimating equations (GEE), was used to model categorical outcomes.670 patients were included. Patients with TBI+HS had significantly higher lactate (median 6.3; IQR 4.7,9.2) compared to the TBI group (median 3.3; IQR 2.3,4). TBI+HS patients had higher activated prothrombin times and lower platelet counts. Unadjusted mortality was higher in the TBI+HS (51.6%) and TBI (50%) groups compared to the HS (17.5%) and neither group (7.7%). Adjusted odds of death in the TBI and TBI+HS groups were 8.2 (95% CI, 3.4-19.5) and 10.6 (95% CI, 4.8-23.2) times higher, respectively. Ventilator, ICU- and hospital-free days were lower in the TBI and TBI+HS groups compared to the other groups. Patients with TBI+HS or TBI had significantly greater odds of developing a respiratory complication compared to the neither group.The addition of TBI to HS is associated with worse coagulopathy prior to resuscitation, and increased mortality. When conrolling for multiple known confounders, the diagnosis of TBI alone or TBI+HS was associated with significantly greater odds of developing respiratory complications.prognostic study LEVEL OF EVIDENCE: II
