With reference to the Year of the Lung, current knowledge of the respiratory effects of current ambient air pollution is reviewed. Acute respiratory effects are well established. Studies such as SAPALDIA and others now shed light on the long-term effects on chronic pathologies and on the health benefit of air quality improvements. The identification of those at highest risk and of local effects of not yet regulated traffic-related pollutants remains a research priority.

ReviewThe stress hormone copeptin: a new prognostic biomarker in acute illness.
Stress is defined as anything that throws the body out of homeostatic balance; for example an acute illness. Any stressor which activates the hypothalamo-pituitary-adrenal (HPA) axis leads to an increase in concentrations of the adrenal stress hormone, cortisol. One of the major hypothalamic stress hormones, which is stimulated by different stressors, is vasopressin (AVP). ⋯ Importantly, interpretation of copeptin levels must always consider the clinical setting. An accurate prognostic assessment has the potential to guide interventions and effectively plan and monitor rehabilitation and, thus optimise the management of individual patients and the allocation of limited health care resources. Future intervention studies must prove the value of copeptin in clinical decision making and in improving the overall medical management of patients with acute illnesses.
