Helmet legislation and admissions to hospital for cycling related head injuries in Canadian provinces and territories: interrupted time series analysis

Tue, 14 May 2013 11:32:18 +0100

While helmets reduce head injuries and their use should be encouraged, this study suggests that, in the Canadian context of provincial and municipal safety campaigns, improvements to the cycling infrastructure, and the passive uptake of helmets, the incremental contribution of provincial helmet legislation to reduce the number of hospital admissions for head injuries is uncertain to some extent, but seems to have been minimal.

Derivation and validation of QStroke score for predicting risk of ischaemic stroke in primary care and comparison with other risk scores: a prospective open cohort study

Thu, 02 May 2013 12:03:48 +0100

This paper concludes that QStroke provides a valid measure of absolute stroke risk in the general population of patients free of stroke or transient ischaemic attack, as shown by its performance in a separate validation cohort.

Use of serum C reactive protein and procalcitonin concentrations in addition to symptoms and signs to predict pneumonia in patients presenting to primary care with acute cough: diagnostic study

Tue, 30 April 2013 11:32:15 +0100

A clinical rule based on symptoms and signs to predict pneumonia in patients presenting to primary care with acute cough performed best in patients with mild or severe clinical presentation. Addition of CRP concentration at the optimal cut off of >30 mg/L improved diagnostic information, but measurement of procalcitonin concentration did not add clinically relevant information in this group.

Can trial quality be reliably assessed from published reports of cancer trials: evaluation of risk of bias assessments in systematic reviews

Mon, 22 April 2013 11:33:54 +0100

According to this study, using cancer trial publications alone to assess risk of bias could be unreliable; thus, reviewers should be cautious about using them as a basis for trial inclusion, particularly for those trials assessed as unclear risk. Supplementary information from trialists should be sought to enable appropriate assessments and potentially reduce or overcome some risks of bias, say the authors, and furthermore, guidance should ensure clarity on what constitutes risk of bias, particularly for the more subjective domains.
