Global sea-surface iodide observations, 1967–2018
The marine iodine cycle has significant impacts on air quality and atmospheric chemistry. Specifically, the reaction of iodide with ozone in the top few micrometres of the surface ocean is an important sink for tropospheric ozone (a pollutant gas) and the dominant source of reactive iodine to the atmosphere. Sea surface iodide parameterisations are now being implemented in air quality models, but these are currently a major source of uncertainty. Relatively little observational data is available to estimate the global surface iodide concentrations, and this data has not hitherto been openly available in a collated, digital form. Here we present all available sea surface (<20 m depth) iodide observations. The dataset includes values digitised from published manuscripts, published and unpublished data supplied directly by the originators, and data obtained from repositories. It contains 1342 data points, and spans latitudes from 70°S to 68°N, representing all major basins. The data may be used to model sea surface iodide concentrations or as a reference for future observations

Undergraduate training in the care of the acutely ill patient : a literature review
Objective: To characterise the problem of teaching acute care skills to undergraduates and to look for potential solutions. Design: Systematic literature review including Medline, EMBASE, CINAHL. Eligible studies described education and training issues focusing on caring for acutely ill patients. Articles were excluded if they did not address either educational or clinical aspects of acute care and resuscitation. Measurement and results: We identified and reviewed 374 articles focusing on training or clinical aspects of caring for the acutely ill patient. Undergraduates and junior physicians lack knowledge, confidence and competence in all aspects of acute care, including the basic task of recognition and management of the acutely ill patient. There is wide variability both between and within countries regarding the amount of teaching in critical care offered to undergraduate medical students. Many centres are starting to use an integrated approach to acute care teaching, with early exposure to basic life support and clinical skills, coupled with later exposure to more complex acute care topics. Clinical attachments remain a popular method for training in acute care. Acute care courses are increasingly being used to standardise delivery of practical skills and patient management training. Conclusion: The training of healthcare staff in the care of acutely ill patients is suboptimal, adding to patient risk. Improvements in training should start at undergraduate level for maximal effect, should be integrated with postgraduate education, and are likely to enhance current efforts to improve patient safety in acute care
