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]
Point-of-care ultrasonography: Moore CL, NEJM 2011;364:749-757.
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]
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]
DeMets & Califf give a historical play-by-play, lament the current state of affairs, and issue a call to arms for academics to leverage the current political climate favoring comparative-effectiveness and translational research, in order to build a new clinical trials edifice that favors the public’s health over profits. JAMA 2011;305:713-714.
Moses & Martin see an impending crisis of public trust in the entire enterprise. They call for an epic shift in national priorities, policy, and funding of research, envisioning a more collaborative, value-based system– while acknowledging that such a sea change would take decades.

Cao et al report experience with 186 patients with resected bronchopulmonary carcinoid in Australia; median survival was 20 years. Those older than 60 at presentation and/or with higher-grade/atypical tumor histopathology had worse survival. Ann Thorac Surg 2011;91:339-343.
The IASLC, ATS, and ERS got together to better incorporate clinical logic into classification of NSCLC. No more bronchioloalveolar carcinoma (they propose adenocarcinoma in situ or invasive mucinous adenocarcinoma, depending on its size). Large cell carcinoma with neuroendocrine features gets separated out of NSCLC entirely, so it can be treated as small cell. And so [... read more]
Song et al retrospectively reviewed 461 cases of IPF (269 biopsy-proven) in Korea. More than a third of patients were hospitalized for respiratory deteriorations over a 2-year period. About half the deteriorations were attributed to acute exacerbations of IPF, with most of the rest attributed to infections (half the patients had BAL and/or ET aspirates [... read more]
The once-daily beta-agonist was better than placebo and at least as good as twice-daily salmeterol, as measured by the SGRQ, TDI, and FEV1 after 12 weeks. The drug previously matched up well against tiotropium. Indacaterol is available in Europe, but not in the U.S. (n=838). ERJ 2011;37:273-279.
McCormack et al randomized 89 women with lymphangioleiomyomatosis to receive 2 mg rapamycin or placebo daily for 12 months, followed by 12 months of drug-free observation. Women receiving sirolimus had stable lung function on spirometry, fewer symptoms, fewer “respiratory events,” and better quality of life during the treatment period. This was tempered by GI, dermatologic, [... read more]

Ciclesonide, a new inhaled corticosteroid that seems to cause thrush less often than others, reached for equivalency with salmeterol/fluticasone in mild persistent asthma. Ciclesonide was better than placebo in controlling asthma but Advair users had a longer time to first asthma exacerbation. CHEST 2011;139: online supplement. A Cochrane review on ciclesonide could not establish its [... read more]
Patients with on-site evaluation of TBNA samples had fewer sites sampled (1 vs. 2) and general complications (6% vs. 20%), with an equivalent yield compared to patients undergoing usual TBNA (n=168). CHEST 2011;139:395-401.
