Tranexamic acid has a small beneficial effect on hemorrhage from trauma or surgery. Among 270 subjects with intracranial hemorrhage due to trauma, those randomized to tranexamic acid showed a trend toward improved outcomes (mortality, hemorrhage extension, new bleeding foci) compared to placebo. Authors propose a large trial to explore further. BMJ 2011;343:d3795. FREE FULL TEXT

New York’s city council banned smoking in almost all public spaces on May 23. Colgrove et al raise the interesting point that because the risk from secondhand smoke outdoors is nil, the political move oversteps the mandate of public health, and is instead heavyhanded social engineering that will further stigmatize smokers, a sad and addicted [… read more]

Menthol doesn’t kill people — cigarettes that are tastier and easier to smoke because of menthol do. The FDA’s Tobacco Products Scientific Advisory Committee blandly concluded that removing menthol from cigarettes would improve public health, but in the current pro-economic recovery environment, there is no political will to take on Big Tobacco, Siegel, Benowitz and [… read more]

Boutitie et al analyzed pooled anticoagulation clinic data from 2,925 people with a first deep venous thrombosis or pulmonary embolism in the UK. They found that the recurrence risk after stopping anticoagulation at 3 months was equivalent to stopping at 6 months. Proximal DVTs were more likely to recur than distal DVTs. BMJ 2011;342:d3036.

Douma et al compared the Wells score, Geneva score, and the simplified versions of each, combined with D-dimer, on a prospective cohort of 807 patients with suspected PE (~23% of whom were found to have PE). With a negative D-dimer and a low-probability score using any rule, risk of pulmonary embolism was ~0.5%. However, only [… read more]

Pileggi et al analyzed 28 studies and concluded that decontaminating the GI/respiratory tract with antiseptics reduced ventilator-associated pneumonia by 27%; decontamination with antibiotics reduced VAP by 36%. Antibiotic decontamination also reduced ICU infections in general, by 29%. Critical Care 2011;15:R155. FREE FULL TEXT Also see last month’s “Oral / gastric antibiotic decontamination reduced bacteremias in [… read more]

Seyler et al prospectively observed 53 patients with sepsis and renal failure on CRRT. Measured at a single point in time after infusion, the concentrations of Zosyn, Ceftaz, and Cefepime at standard dosing regimens were all deemed suboptimal by the authors. Meropenem performed slightly better. Critical Care 2011;15:R137. FREE FULL TEXT

Elliott et al (of ANZICS) randomized 195 survivors of >24h mechanical ventilation to get 3 home physical therapy visits and telephone support, or usual care, over the 8 weeks after hospital discharge. At 26 weeks, there was no difference in 6-minute walk, quality-of-life measures, or objective physical function measures. (n=195) Critical Care 2011;15:R142. FREE FULL [… read more]

Jones et al randomized 1,647 people with moderate to severe COPD for the two trials, to receive either aclidinium inhaled (a potential tiotropium competitor) once daily or placebo for 1 year. Aclidinium improved FEV1 by ~65 mL. An absolute ~8% more people taking the drug achieved a 4-point SGRQ improvement over those taking placebo. Time [… read more]

Prone positioning improves oxygenation in ARDS patients without improving outcome. Recruitment maneuvers do too. Rival et al prospectively tested the effects of both strategies together in 16 ARDS patients. Two extended sighs of 45 cm H2O in pressure control mode while lying prone improved PaO2/FiO2 from 98 to 166 mm Hg, without obvious adverse (or positive) effects. Critical [… read more]

Waters et al tested 136 meat and poultry samples in U.S. grocery stores, and found 77% of the turkey, 42% of pork, 41% of chicken, and 37% of beef were contaminated with S. aureus. 96% of the isolates were resistant to at least one drug, and 52% of isolates were resistant to 3 antibiotic classes. In the Netherlands, [… read more]

Sacanella et al prospectively observed 230 generally healthy, cognitively intact, highly functional & independently living Spaniards 65 years or older (mean age 75) after urgent admission to a single MICU. About half received mechanical ventilation (54%). Seventy died in-hospital; 48 died within a year, for a one-year survival of 49%. But among the 112 survivors, [… read more]

In a 5-week prospective observational study in 47 Australian & New Zealand ICUs, Pettila et al (the ANZICS group) followed 757 ICU patients receiving red blood cell transfusions for anemia of any cause. Those in the quartile receiving the youngest RBCs (mean age 7.7 days) had an absolute 8% lower mortality than the other 3 [… read more]

A systematic review of 3 trials (n=337) by the Bed Head Elevation Study Group (not to be confused with the Bedhead photo group) found no good evidence that head-of-bed (HOB) elevation to 45′ helps or harms in any way (pneumonia, decubiti, mortality, VTE, or hemodynamic instability). Nevertheless, a consensus panel of 22 experts agrees with previous [… read more]

Remember when you were a third year medical student? Me neither. But that’s when you first started to build that tough & isolating carapace to protect you from all the overwhelming emotions flying through the hospital, & you, this essay suggests. A seasoned clinical educator and a third-year med student have a conversation about our [… read more]
