Accurso et al report phase 3 results from industry-funded TIGER-1, testing t.i.d. inhaled denufusol (an ion channel regulator that alters sodium/chloride transport to improve mucociliary clearance) vs. placebo in early cystic fibrosis (FEV1>74% predicted). After 24 weeks, FEV1 was 45 mL better in the treated group, most of whom were younger than age 19. There [… read more]
Lymphangioleiomyomatosis. Harari S, Eur Resp Review 2011;20:34-44. LAM review.
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]

Valdyanathan et al gave prednisolone 25 mg (equivalent to prednisone) or placebo daily for 2 weeks to sufferers of chronic rhinosinusitis in the UK, followed by 8 months of nasal fluticasone (drops, then spray) for all. The orally-treated group had a 2.1-point fall in their polyp grade and could smell better, at 6 months. Ann [… read more]

How “hard” should we “hit” our patients with Lasix? And does that hurt? Felker et al asked that (sort of) in a NHLBI-funded trial. They gave furosemide to 308 patients hospitalized for ADHF in an IV dose either equivalent to their home dose, or at 2.5 times their home dose, and either at q12-hour intervals [… read more]

Imaging, airflow, rhinosinusitis, congestion, allergies, the sense of smell … more than a dozen articles on “the other airway” is nothing to sneeze at. Proc Am Thorac Soc 2011; 8: 1-140.
In a rare encouraging positive study in the chronically critically ill, 71% of vent-dependent patients (~6 weeks on MV) who did multiple sets of daily inspirations backwards through a PEEP valve weaned from mechanical ventilation (defined as >72 hrs off the vent), vs. 47% receiving a sham treatment. MIP also improved by 10 cmH2O in [… read more]

Tashkin et al randomized 504 patients at 27 centers with COPD and FEV1 > 49% to varenicline or placebo for 12 weeks, with 52 weeks follow up. Smoking cessation / abstinence rate (carbon monoxide-confirmed) was 42% vs 9% in weeks 9 – 12 (1′ endpoint), and 19% vs. 6% in weeks 9 – 52 (p<0.0001). [… read more]

Chai-Coetzer et al designed and validated a predictive model for diagnosing obstructive sleep apnea without polysomnography in 157 general primary care patients considered at average risk for obstructive sleep apnea. Berlin/Epworth questionnaires, snoring, waist size, witnessed apneas and age were fit into an algorithm, followed by home oximetry in a sample of mostly high-Berlin-scoring patients. [… read more]
Using Medicare records from more than 30,000 beneficiaries with congestive heart failure, Javaheri et al suggest in this observational epidemiologic study that sleep apnea may be woefully overlooked and undertreated in people with CHF. The 2% of the cohort who were tested and treated for sleep apnea had one-third the 2-year mortality of their risk-matched [… read more]
MedPAC wants the next generation of MDs to be cost-conscious, evidence-minded, and amenable to standardization of care. To prod GME programs to train young MDs thusly, the influential government advisory body recommends allocating $3.5B of the $9.5B annual GME outlay as at-risk incentive payments. A proposed committee would have 3 years to design metrics for [… read more]
