National guidelines and government directives have adopted policies for urgent assessment of patients with a transient ischaemic attack or minor stroke not admitted to hospital. The risk of recurrent stroke increases substantially with age, as does the potential benefit of secondary prevention. In order to develop effective strategies for older patients, it is important to identify how stroke care is currently provided for this patient group. ⋯ Older patients were less likely to receive diagnostic investigations and lifestyle modification advice than younger patients. Guidelines need to be adopted to ensure prompt evidence-based stroke care in the outpatient setting.

Many drugs such as low molecular weight heparin (LMWH) are administered at "patient weight adjusted" doses. Obtaining an accurate measurement of a patient's weight may not always be possible. The aim of this study was to assess patterns and accuracy of weight estimation and implications for drug dosing. ⋯ In our institution weight estimation occurs and may result in inaccurate prescription of LMWH. Estimating a patient's weight should be discouraged but if necessary the patient reported weight is likely to be most accurate. Unless there is significant investment in improved technology to allow obese or acutely unwell patients to be weighed, the dangerous practice of weight estimation is likely to continue.

A plethora of biomarkers are becoming available in the field of respiratory medicine, but their application in clinical practice has been limited. This is changing. There is increasing scope for biomarkers to be used to define pathological as well as treatment responder phenotypes in asthma and chronic obstructive pulmonary disease. ⋯ Biomarkers are potentially very important in the development and assessment of new therapeutic agents, particularly for the treatment of severe asthma. They also have a potential role in monitoring disease activity and predicting future clinical outcomes for asthma and chronic obstructive pulmonary disease. Current evidence in relation to these issues is explored in this review.
