This week’s ‘R&R Hall of Famers

  • EINSTEIN–PE Investigators. Oral Rivaroxaban for the Treatment of Symptomatic Pulmonary Embolism. N Engl J Med. 2012 Mar 26. [Epub ahead of print] PubMed PMID: 22449293
R&R in the FASTLANE 009 RR GameChanger 64 R&R in the FASTLANE 009 RR Hall of fame 64 R&R in the FASTLANE 009 RR Hot Stuff 64 This one is a game-changer. A single oral agent is non-inferior to a heparin / warfarin protocol in patients with symptomatic pulmonary embolism. Other –xabans are in the pipeline. Apixaban will probably be even better than rivaroxaban. Now if someone would only be brave enough to compare –xabans to nothing, we would have even more valuable information.

This week’s R&R recommendations

  • Schulman S, Crowther MA. How I treat with anticoagulants in 2012: new and old anticoagulants, and when and how to switch. Blood. 2012 Mar 29;119(13):3016-23. Epub 2012 Feb 1. PubMed PMID: 22302737.
R&R in the FASTLANE 009 RR Mona Lisa 64 Great review of novel oral anticoagulants, from ‘what’ to ‘how to’
(All quoted trials are outpatients or non-ICU in-patients. Lots of pharmacokinetic extrapolation, not so much hard evidence).
Warfarin still tops for AF and DVTs if stable therapeutic INR, poor compliance, GI (any) bleeding concerns, creatinine clearance <30ml/min, limited budget. 4-factor PCC seems to be the only potential reversal agent and add 6 hours of dialysis for dabigatran.
(Just wonder if rivaroxaban would be a target for intralipid as an antidote!?)

R&R in the FASTLANE 009 RR GameChanger 64 R&R in the FASTLANE 009 RR Boffin 64 Does your patient’s low back pain pain have an organic cause? Probably not if they react to the heel-tap test: “The patient sits on the examination couch with his hips and knees flexed to 90°. After suggesting that the test may cause lower back pain, the examiner lightly taps the patient’s heel with the base of his hand. If the patient complains of sudden lower back pain, the test is considered to be positive.” The paper also describes Waddell’s signs, with which this simple test compares favourably.

  • Jensen MC, Brant-Zawadzki MN, Obuchowski N, Modic MT, Malkasian D, Ross JS. Magnetic resonance imaging of the lumbar spine in people without back pain. N Engl J Med. 1994 Jul 14;331(2):69-73. PMID: 8208267.
R&R in the FASTLANE 009 RR Eureka 64 R&R in the FASTLANE 009 RR Mona Lisa 64 This is an classic. Lumbar MRI scans 100 hospital employees with no back pain or history of it. Read by two radiologists with clear definitions of what to report. Kappa 0.59. Much more interestingly almost 70% of these asymptomatic people had abnormalities. Most were bulges but a quarter were “protrusions” and almost 10% had facet disease. MR great for cauda equina but maybe not for telling us what causes your patient’s back pain…

R&R in the FASTLANE 009 RR GameChanger 64 In contrast to the beneficial placebo effect, the term “nocebo effect” describes “adverse effects produced by expectations”. For example, a certain number of research subjects will develop described side effects attributed to a study drug, even if they end up in the placebo arm. This interesting paper discusses important clinical and ethical issues related to this phenomenon.

R&R in the FASTLANE 009 RR Mona Lisa 64 R&R in the FASTLANE 009 RR GameChanger 64 A great discussion of the pros and cons of different methods for stemming hemorrhange from pelvic fractures. The authors ultimately advocate going to the OR for preperitoneal packing prior to angiography for hemodynamically unstable patients.
