Early case recognition and intervention by nurses for patients with mild traumatic brain injury (mTBI) can significantly improve outcomes for civilian and military patients. The "Concussion/mTBI Learning Needs Assessment for Registered Nurses Survey" was developed to evaluate bedside nurses' knowledge related to the assessment and care of patients with mTBI as well as their preferences for learning in order to develop a targeted curriculum. An anonymous, self-administered, Web-based survey was available from February to August 2009. ⋯ The nurses' preferred learning method was shadowing another provider (37%), but the most often used method was Internet searches (80.3%). There was minimal difference between military and civilian nurses. Although nurses recognize the importance of familiarity with mTBI for their practice and most clearly self-identify knowledge deficits in all aspects of care of the mTBI patients, a broad but succinct curriculum for the nonadvanced practice bedside nurse could provide a cost-effective, quickly accessible way to provide the needed education.

Treatment of acute stroke is difficult due to the complexity of events triggered by ischemic insult. Current reperfusion strategies are time limited and, alone, may not be sufficient to achieve maximal neurologic outcomes. Therapeutic hypothermia (TH) appears to be a promising neuroprotective therapy, as it affects a wide range of destructive mechanisms occurring in ischemic brain tissue. ⋯ Human studies utilizing TH in acute stroke have shown trends toward positive effects; however, there have been a variety of measurements and methods making comparisons difficult. The ideal protocol for the use of TH in stroke has not yet been developed and requires determination of optimal depth, duration, and methods of temperature measurement and cooling for acute stroke. The purposes of this article were to (1) discuss the effects of ischemia and reperfusion in acute stroke, (2) discuss how TH can potentially limit neurological injury, and (3) review current literature on the use of hypothermia as a treatment for acute stroke.

Delirium is a common cause of functional and cognitive decline, morbidity, and mortality among hospitalized elderly individuals. Several studies reveal that the prognosis of delirium is worse among elderly individuals with severe delirium. In light of these findings, it is important to identify which factors are associated with delirium severity: individual (predisposing) or environmental (precipitating) factors. ⋯ In multivariate analysis, only marital status (being married) and severity of dementia remained statistically associated with delirium severity. Results of this study provide further evidence that the weakened brain functions of persons with dementia increases not only the risk of delirium but also its severity. Given the poor outcomes associated with delirium severity, nurses need to pay closer attention to the predisposing and precipitating factors of delirium severity.

Stress-induced hyperglycemia has been associated with poor outcomes and death in critically ill patients. Blood glucose (BG) variability, a component of stress-related hyperglycemia has recently been reported as a significant independent predictor of intensive care unit and hospital mortality. We sought to evaluate three cases in which intensive insulin therapy was administered using a standardized insulin dosing protocol to normalize the BG and reduce glycemic variability. ⋯ In each instance, BG variability was present in a worsening patient condition after a period of normalization of hyperglycemia with intensive insulin therapy. Although decreasing BG variability is an important aspect of hyperglycemia management, new onset events of variability may be a sentinel warning or occur as a physiologic response to a worsening patient condition. If so, these events warrant rapid investigation and treatment of the underlying problem.
