No one knows, say Lee et al. They report on 27 Korean soldiers who were exposed to 5 barracks-mates with active TB; 26 eventually “converted” by tuberculin skin test/PPD or by interferon-gamma release assay. One-time TST/PPD identified 21, or 78%. IGRA every two weeks eventually diagnosed 26 (96%), but it took 14 weeks for 3 [... read more]

Gershengorn et al retrospectively compared two MICUs at Beth Israel: one with “midlevels” (nurse practitioners and physician assistants during the day with attending coverage overnight) and one that was all house staff 24/7. There were no differences in important outcomes (mortality, MICU or hospital LOS), although the study was nonrandomized and subject to bias. CHEST [... read more]

Salaun et al publish their experience using a simple algorithm for management of 321 consecutive patients with suspected pulmonary embolism at one center in France. The tool sought to avoid CT-angiography (and associated radiation) wherever possible, instead favoring leg ultrasounds and ventilation-perfusion scans. Only the indeterminate cases (a mere 35, or 11%) underwent CT-A. In [... read more]

In association with United Biosource Corp., Jones et al are championing a patient questionnaire called EXACT-PRO that seeks to standardize the definition of a COPD exacerbation. Here, they report on the production of their proposed 14-item measure to diagnose and grade the severity of COPD exacerbations. Breathlessness, cough-and-sputum, and chest symptoms form the core of [... read more]

Taveira-DaSilva reports an observational series of 19 women treated with sirolimus for lymphangioleiomyomatosis. Of 12 women with chylous pleural effusions, most had a large improvement or resolution in their effusions. Ann Intern Med 2011;154:797-805. In a randomized trial of 89 LAM patients published in NEJM March 2011, sirolimus reduced decline of lung function.

The New York Times reported that hundreds of community hospitals frequently perform two chest CT scans back-to-back (one with, one without IV contrast), while academic centers almost never do. More than 70,000 patients were double-scanned; some hospitals did it >80% of the time on their Medicare chest patients. Defenders say they don’t do it to [... 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 et al randomized 5,800 UK ready-to-quit smokers to get regular motivational text messages and help-line access, vs. placebo (texts thanking them for participating). At 6 months, those getting motivational text messages had biochemically-verified continuous abstinence of 11%, vs. 5% in the controls. Verification was by salivary cotinine at 6 months (& showed that 28% [... read more]

Meijvis et al randomized 304 people hospitalized with CAP in the Netherlands to receive dexamethasone (5 mg) or placebo daily for 4 days on admission. Those getting steroids had a ~1 day shorter length of stay and no adverse effects, besides hyperglycemia. Patients were ill, with almost half having a pneumonia severity index/PORT class of [... read more]

TNF-alpha can be elevated in severe asthmatics’ sputum and bronchial tissue. Could blocking it help? Holgate et al randomized 132 people with moderate or severe persistent asthma to receive 25 mg etanercept or placebo injections for 12 weeks. There was no difference in the primary endpoint (change in FEV1 at 12 weeks) nor in exacerbations, [... 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]
