Multicenter Study
Monocyte chemoattractant protein-1 is not predictive of cardiac events in patients with non-low-risk chest pain.
Prior studies suggest monocyte chemoattractant protein-1 (MCP-1) may be useful for risk stratifying ED patients with chest pain. We hypothesise that MCP-1 will be predictive of 90-day major adverse cardiovascular events (MACEs) in non-low-risk patients. ⋯ MCP-1 is not predictive of 90-day MACE in patients with non-low-risk chest pain.

Advances in imaging technologies have precipitated uncertainty and inconsistency in the management of neurologically intact patients presenting to the Emergency Department (ED) with non-traumatic sudden onset severe headache with a clinical suspicion of subarachnoid haemorrhage (SAH). The objective of this systematic review was to evaluate diagnostic strategies in these patients. ⋯ The Ottawa SAH Rule rules out further investigation in only a small proportion of patients. CT undertaken within 6 hours (with expertise of a neuroradiologist or radiologist who routinely interprets brain images) is highly accurate and likely to be sufficient to rule out SAH; CT beyond 6 hours is much less sensitive. The CT-LP pathway is highly sensitive for detecting SAH and some alternative diagnoses, although LP results in some false positive results.

This study explored the perspectives and behaviours of emergency physicians (EPs), regularly involved in resuscitation, to identify the sources and effects of any stress experienced during a resuscitation as well as the strategies employed to deal with these stressors. ⋯ Stress is commonly experienced by EPs during resuscitation and can impact decision-making and procedural performance. This study identifies the most common sources of stress during a resuscitation as well as the strategies that EPs use to mitigate the effects of stress on their performance. These findings may contribute to the development of tailored stress management training for critical care clinicians.
