- Air quality transcends all scales with in the atmosphere from the local to the global with handovers and feedbacks at each scale interaction. Air quality has manifold effects on health, ecosystems heritage and, climate. In this review the state of scientific understanding in relation to global and regional air quality is outlined. The review discusses air quality, in terms of emissions, processing and transport of trace gases and aerosols. New insights into the characterization of both natural and anthropogenic emissions are reviewed looking at both natural (e.g. dust and lightning) as well as plant emissions. Trends in anthropogenic emissions both by region and globally are discussed as well as biomass burning emissions. In terms of chemical processing the major air quality elements of ozone, non-methane hydrocarbons, nitrogen oxides and aerosols are covered. A number of topics are presented as a way of integrating the process view into the atmospheric context; these include the atmospheric oxidation efficiency, halogen and HOx chemistry, nighttime chemistry, tropical chemistry, heat waves, megacities, biomass burning and the regional hot spot of the Mediterranean. New findings with respect to the transport of pollutants across the scales are discussed, in particular the move to quantify the impact of long-range transport on regional air quality. Gaps and research questions that remain intractable are identified. The review concludes with a focus of research and policy questions for the coming decade. In particular, the policy challenges for concerted air quality and climate change policy (co-benefit) are discussed.

- Background: In the late 1990s, several professional organizations convened antiemetic guideline groups and published the findings of these expert panels. Each of these documents was based on analyses of the available published trials and provided nearly similar recommendations. Nonetheless, small differences in emetic risk categories and treatment recommendations led to confusion in antiemetics selection. With the emergence of new findings and agents since the guidelines were initially published, many of the oncology professional societies have updated the antiemetic guidelines. Materials and methods: A literature review up to March 2004 was carried out using MEDLINE with evaluation of the evidence by an expert panel composed of 23 oncology professionals in clinical medicine, medical oncology, radiation oncology, oncology nursing, statistics, pharmacy, medical policy and decision making, and pharmacology. The experts represented nine oncology professional societies and came from 11 different countries on four continents. Results: Recommendations on antiemetic regimens to prevent emesis induced by high, moderate, low and minimal risk chemotherapy were suggested as well as management of anticipatory emesis. Furthermore, recommendations for refractory emesis, emesis induced by high-dose chemotherapy and radiotherapy and for antiemetics in children receiving chemotherapy were elaborated. Conclusions: Recommendations about antiemetic prophylaxis in patients receiving treatment with chemo- and radiotherapy have been updated by representatives of nine oncological organizations. © 2005 European Society for Medical Oncology.
