Iyer et al re-checked PFTs on 1,284 people with nonspecific results (low FEV1 or FVC but normal TLC and FEV1/FVC ratio), at a median of 3 years after the abnormal test. 64% continued to have the nonspecific result; 16% had restriction; 15% had obstruction; 2% had a mixed pattern; 3% were normal. They recommend changing [... read more]
Pulmonary hypertension is often “diagnosed” with a tricuspid regurgitant jet velocity > 2.5 m/s on echocardiogram. Bossone et al found that 76 of 615 (12%) trained athletes (strength or endurance) exceeded this number, and suggest the upper limit of normal should be 40 mm Hg in endurance athletes. CHEST 2011;139:788-794.
Interviewing 100 patients or their surrogates in the ICU, 85% of whom were “full code,” Gehlbach et al found 16% of patients’ code status in the chart did not correlate with their expressed preferences during the interview (10 wanted less care, 6 wanted more). Respondents’ average prediction for their survival should they have a cardiac [... read more]
Cryptogenic and secondary organizing pneumonia: Drakopanagiotakis F et al, CHEST 2011;139:893-900. COP and BOOP review.
20% of U.S. deaths now occur during or soon after an ICU stay — but the families live on, often with upsetting memories, depression, and anxiety. Kross et al re-heat data from the IPACC palliative care study in Washington, surveying family members of ICU decedents, showing they had a 14% prevalence of PTSD symptoms and 18% of [... read more]

Fang et al prospectively observed 126 patients undergoing lung transplant at 9 U.S. centers. PA pressure was obtained invasively in the OR just after transplant. Those who developed grade 3 primary graft dysfunction at 72 hours (1′ endpoint) had mPAP of 38.5 mm Hg, compared to 29.6 for those who did not; the relationship persisted [... read more]
Psychiatrist Aaron Lazare from U-Mass has been writing and thinking about humiliation in medical education and practice for years. This engrossing article exposes the destructiveness and persistence of this toxic emotion that he argues is sadly endemic in our profession. CHEST 2011;139:746-751.
Long-term oxygen therapy: Christopher KL & Porte P, CHEST 2011;139:430-440
THIS STUDY HAS BEEN RETRACTED. Kupfer et al looked retrospectively at 168 vented patients with transudative pleural effusions at Maimonides in Brooklyn. The half that got chest tubes (with an average of 1,200 mL drained) spent 3.8 days on the vent, vs 6.5 days for the group that got only thoracentesis, with no complications reported. [... 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]

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.
