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.

Population-Based Burden of COPD-Related Visits in the ED: Return ED Visits, Hospital Admissions, and Comorbidity Risks.
Little is known about the population-based burden of ED care for COPD. ⋯ The population-based burden of COPD-related care in the ED is significant. Further research is needed to understand variations in COPD-related ED visits and hospital admissions.

Although physiotherapy is frequently provided to patients in the ICU, its role has been questioned. The purpose of this systematic literature review, an update of one published in 2000, was to examine the evidence concerning the effectiveness of physiotherapy for adult, intubated patients who are mechanically ventilated in the ICU. ⋯ Available new evidence, published since 1999, suggests that physiotherapy intervention that comprises early progressive mobilization is beneficial for adult patients in the ICU in terms of its positive effect on functional ability and its potential to reduce ICU and hospital length of stay. These new findings suggest that early progressive mobilization should be implemented as a matter of priority in all adult ICUs and an area of clinical focus for ICU physiotherapists.

Rhabdomyolysis is a well-known clinical syndrome of muscle injury associated with myoglobinuria, electrolyte abnormalities, and often acute kidney injury (AKI). The pathophysiology involves injury to the myocyte membrane and/or altered energy production that results in increased intracellular calcium concentrations and initiation of destructive processes. Myoglobin has been identified as the primary muscle constituent contributing to renal damage in rhabdomyolysis. ⋯ There is little evidence other than from animal studies, retrospective observational studies, and case series to support the routine use of bicarbonate-containing fluids, mannitol, and loop diuretics. Hyperkalemia and compartment syndrome are additional complications of rhabdomyolysis that must be treated effectively. A definite need exists for well-designed prospective studies to determine the optimal management of rhabdomyolysis.

Cardiovascular Safety in Patients Receiving Roflumilast for the Treatment of COPD.
Evaluation of cardiovascular safety for new therapies for COPD is important because of a high prevalence of cardiac comorbidities in the COPD population. Hence, we evaluated the effects of roflumilast, a novel oral phosphodiesterase 4 inhibitor developed for the treatment and prevention of COPD exacerbations, on major adverse cardiovascular events (MACEs). ⋯ A lower rate of cardiovascular events was observed with roflumilast than with placebo in patients with COPD, indicating the lack of a cardiovascular safety signal when treating patients with COPD. Potential cardiovascular benefits of roflumilast should be evaluated in future controlled clinical trials.
