Transformation of the rapidly proliferating quantities of experimental information into a usable form in order to facilitate their analysis is a challenging task. On this track, bioinformatics, an essential part of proteomics research, aspires to amend inquiries into a better manipulated, a better handled and a better understood form so as to enhance existing knowledge expansion.”
“Background:

Arterial carbon dioxide tension (PaCO2) affects neuronal function and cerebral blood flow. However, its association with outcome in patients admitted to intensive care unit (ICU) after cardiac arrest (CA) has not been evaluated.

Methods and results: Observational cohort study using data from the Australian New Zealand (ANZ) Intensive Care Society Adult-Patient-Database (ANZICS-APD). Outcomes analyses were adjusted for illness severity, co-morbidities, hypothermia, treatment check details limitations, age, year of admission, glucose, source of admission, PaO2 and propensity score.

We studied 16,542 consecutive patients admitted to 125 ANZ ICUs after CA between 2000 and 2011. Using the APD-PaCO2 (obtained within 24 h of ICU

admission), 3010 (18.2%) were classified into the hypo( PaCO2 < 35 mmHg), 6705 (40.5%) into the normo-(35-45 mmHg) and 6827 (41.3%) into the hypercapnia (>45 mmHg) group. The hypocapnia group, compared with the normocapnia group, had a trend toward higher in-hospital mortality (OR 1.12 [95% CI 1.00-1.24, p = 0.04]), lower rate of discharge home (OR 0.81 [0.70-0.94, p < 0.01]) and higher likelihood of fulfilling selleck products composite adverse outcome of death and no discharge JIB-04 cost home (OR 1.23 [1.10-1.37, p < 0.001]). In contrast, the hypercapnia group had similar in-hospital mortality (OR 1.06 [0.97-1.15, p = 0.19]) but higher rate of discharge home among survivors (OR 1.16 [1.03-1.32, p = 0.01]) and similar likelihood of fulfilling the composite outcome (OR 0.97 [0.89-1.06, p = 0.52]). Cox-proportional hazards modelling supported these findings.

Conclusions: Hypo-and hypercapnia are

common after ICU admission post-CA. Compared with normocapnia, hypocapnia was independently associated with worse clinical outcomes and hypercapnia a greater likelihood of discharge home among survivors. (C) 2013 Elsevier Ireland Ltd. All rights reserved.”
“Ventilator associated pneumonia is a common and costly complication in critically ill and injured surgical patients. The diagnosis of pneumonia remains problematic and non-specific. Using clinical criteria, a diagnosis of pneumonia is typically not made until an infection is well established. Semi-quantitative cultures of endotracheal aspirate and broncho-alveolar lavage are employed to improve the accuracy of diagnosis but are invasive and require time for culture results to become available. We report data that show that an inexpensive, rapid and non-invasive alternative may exist. In particular we show that: 1).
