ABSTRACT BACKGROUND Midrange-proadrenomedullin (MR-proADM) has been shown to be elevated in patients hospitalized for an acute exacerbation of COPD (AECOPD) and in patients with community acquired pneumonia. MR-proADM when measured during AECOPD has also been shown to be a predictor for mortality, we hypothesized that MR-proADM levels measured in a stable state could also predict mortality. METHODS We included 181 patients in whom we had paired plasma samples for MR-proADM determinations during stable state and at hospitalization for AECOPD when they also produced sputum. ⋯ The corrected Odds Ratio for one year mortality was 8.90 (95% CI 1.94 - 44.6) in patients with high MR-proADM levels measured in stable state, compared to patients with low levels. CONCLUSIONS MR-proADM measured in stable state showed to be a strong predictor for mortality in COPD patients. MR-proADM is far more convenient to measure than other predictors for mortality in COPD such as the BODE score.

Randomized Controlled Trial Multicenter Study Comparative Study
Longitudinal trends in health-related quality of life in adults with cystic fibrosis.
Health-related quality-of-life (HRQOL) measures have been used as patient-reported outcomes in clinical trials in cystic fibrosis (CF), but there are limited data on HRQOL changes over time in adults with CF. ⋯ In a longitudinal multicenter population of adults with CF, clinical variables such as FEV1, exacerbation frequency, and weight were correlated with related CFQ-R subscales. For the population as a whole, the physical domains of CFQ-R, such as respiratory symptoms, were stable. In contrast, population changes in several psychosocial domains of CFQ-R suggest that differentiating between the physical and the psychosocial trajectories in health among adults with CF is critical in evaluating patient-reported outcomes.

American Thoracic Society guidelines support using fractional exhaled nitric oxide (FENO) measurements in patients with asthma and highlight gaps in the evidence base. Little is known about the use of FENO levels to predict asthma exacerbations among high-risk, urban, minority populations receiving usual care. ⋯ FENO level may not be a clinically useful predictor of health-care use for asthma exacerbations in urban minority children with asthma.

Thoracic duct injury is a rare but serious complication following surgery of the neck or chest that leads to uncontrolled chyle leak. Conventional management includes drainage, nutritional modification, or aggressive surgical interventions such as thoracic duct ligation, flap coverage, fibrin glue, or talc pleurodesis; few successful medical therapeutics are available. ⋯ Chyle output decreased substantially after initiating midodrine, an α1-adrenergic agonist that causes vasoconstriction of the lymph system, reducing chyle flow. This case report suggests that midodrine may be a novel therapeutic for refractory chyle leaks.

Comparative Study
Usefulness of cardiothoracic chest ultrasound in the management of acute respiratory failure in critical care practice.
This study investigated the clinical relevance of early general chest ultrasonography (ie, heart and lung recordings) in patients in the ICU with acute respiratory failure (ARF). ⋯ The use of cardiothoracic ultrasound appears to be an attractive complementary diagnostic tool and seems able to contribute to an early therapeutic decision based on reproducible physiopathologic data.
