Uric acid, allopurinol therapy, and mortality in patients with acute heart failure--results of the Acute HEart FAilure Database registry.
The aim of this study was to explore the prognostic role of serum uric acid (UA) measurement in the hospital and long-term mortality assessment in subjects with acute heart failure (AHF) from the Acute HEart FAilure Database registry (AHEAD). The AHEAD registry comprised 4153 patients with AHF syndromes hospitalized at the AHEAD participating centers. ⋯ In patients with AHF, increased UA levels and documented allopurinol therapy for hyperuricemia were associated with increased hospital and long-term mortality. Allopurinol therapy is not a cause but the identifier of the subjects at risk.

Predicting the need for mechanical ventilation in acute exacerbations of chronic obstructive pulmonary disease: comparing the CURB-65 and BAP-65 scores.
Clinicians lack a validated tool for risk stratification for need for mechanical ventilation (MV) in acute exacerbations of chronic obstructive pulmonary disease (AECOPD). We sought to compare 2 risk scores, BAP-65 and CURB-65, at predicting a need for MV in AECOPDs. ⋯ BAP-65 identifies patients with AECOPD at high risk for need of MV more accurately than does CURB-65. BAP-65 may represent a useful tool for initial MV risk stratification in AECOPD.

Multicenter StudyBarriers to feeding critically ill patients: a multicenter survey of critical care nurses.
The aims of this study were to describe the barriers to enterally feeding critically ill patients from a nursing perspective and to examine whether these barriers differ across centers. ⋯ Nurses in our multicenter survey identified important barriers to providing adequate enteral nutrition to their critically ill patients. The importance of these barriers does not appear to differ significantly across different clinical settings. Future research is required to evaluate if tailoring interventions to overcome these identified barriers is an effective strategy of improving nutrition practice.

Randomized Controlled TrialEnd-expiratory lung volume recovers more slowly after closed endotracheal suctioning than after open suctioning: a randomized crossover study.
Endotracheal suctioning causes significant lung derecruitment. Closed suction (CS) minimizes lung volume loss during suction, and therefore, volumes are presumed to recover more quickly postsuctioning. Conflicting evidence exists regarding this. We examined the effects of open suction (OS) and CS on lung volume loss during suctioning, and recovery of end-expiratory lung volume (EELV) up to 30 minutes postsuction. ⋯ Closed suctioning minimized lung volume loss during suctioning but, counterintuitively, resulted in slower recovery of EELV postsuction compared with OS. Therefore, the use of CS cannot be assumed to be protective of lung volumes postsuctioning. Consideration should be given to restoring EELV after either suction method via a recruitment maneuver.

ReviewUncommon ophthalmologic disorders in intensive care unit patients.
Ophthalmologic complications are frequently encountered in intensive care unit (ICU) patients (Grixti et al. Ocul Surf 2012;10(1):26-42). However, eye care is often overlooked in the critical care setting or just limited to the ocular surface because treatment is focussed on the management of organ failures. ⋯ The most prevalent ophthalmologic disorders identified in critically ill subjects include exposure keratopathy, chemosis, and microbial keratitis. In addition, uncommon eye disorders reported in ICU include metastatic endogenous endophthalmitis, acute primary angle closure, ischemic optic neuropathy, pupil abnormalities, vascular occlusions, and rhino-orbital cerebral mucormycosis. Early diagnosis and effective treatment will help to prevent visual loss.
