Workshop on molecular diagnostics for respiratory tract infections: Procalcitonin shows promise as a biomarker for differentiating bacterial from viral pneumonias, and to assess response to therapy. Rapid PCR for MRSA in sputum may become available after further development & testing. Molecular tests for S. pneumonia in respiratory secretions currently are uninterpretable in practice, due to [… read more]

Sadaka et al add their two cents and a cohort study to the Xigris efficacy/safety debate. In their retrospective, propensity-matched analysis of 563 patients sourced from the Project IMPACT database, the 108 who received activated protein C had 35% mortality, vs 54% for the 108 who did not (p=0.005). There were unusually low rates of [… read more]
Hooman et al pooled 5 randomized trials with 112 patients, who had 184 episodes of elevated intracranial pressure. They concluded hypertonic saline is better at reducing ICP; but the relative-risk-for-ICP-control confidence interval was 1.0-1.3 and the mean ICP reduction included zero (-1.6 to 5.7 mm Hg). So, maybe. Crit Care Med 2011;39:554-559.
Cochrane systematic review and meta-analysis: Pooling 11 randomized trials, n=1,971, Blackwood et al suggested there are some benefits to using a standardized weaning protocol. There was a reduction in weaning and ventilation time in the groups that had weaning protocols; we won’t report them here, because they would be misleading in this small space. They [… read more]
Drospirenone is the new progesterone analog in heavily marketed new oral contraceptive pills (trade names Yaz, Yasmin, Angelique). Using a large insurance claims database, Jick et al identified 186 cases of DVT or PE in women aged 15-44 taking oral contraceptives and compared them to controls. Those taking drospirenone-containing OCPs had a nonfatal DVT/PE incidence [… read more]

Warfarin is the best drug for stroke prevention in atrial fibrillation. In people with a-fib for whom warfarin was unsuitable (unstable INR, unlikely adherence, etc, but excluding those with prior bleeding on warfarin), twice daily oral direct Xa inhibitor apixaban had a hazard ratio of 0.45 over aspirin for the primary outcome of stroke (absolute [… read more]
