In patients receiving mechanical ventilation, rapid detection of sTREM-1 in bronchoalveolar-lavage fluid may be useful in establishing or excluding the diagnosis of bacterial or fungal pneumonia.
This prospective study, including inceptive and validation cohorts of unselected intensive care unit patients, demonstrates the high performance of a bioscore combining the PMN CD64 index together with PCT and sTREM-1 serum levels in diagnosing sepsis in the critically ill patient.
Although numerous uncertainties remain (type and the number of strains to use, delay and length of administration), and despite an acceptable safety profile, the daily prophylactic administration of probiotics cannot be encouraged in the critically ill patient.
A progressive decline of plasma sTREM-1 concentration indicates a favorable clinical evolution during the recovery phase of sepsis. In addition, baseline sTREM-1 level may prove useful in predicting outcome of septic patients.
Median HMGB1 concentration was 4.4 ng/ml (IQR 1.2-12.5) at admission, with no difference between survivors and nonsurvivors. A positive correlation was observed between HMGB1 and SOFA score and lactate, and procalcitonin concentrations. There was a progressive but statistically nonsignificant decline in HMGB1 concentration among the survivors, while nonsurvivors showed an increase in HMGB1 level between days 1 and 3. SOFA score and lactate and procalcitonin concentrations did not vary significantly between days 1 and 3. When measured on day 3, HMGB1 discriminated survivors from nonsurvivors with 66% sensitivity and 67% specificity, and concentration greater than 4 ng/ml was associated with an odds ratio of death of 5.5 (95% CI 1.3-23.6).
Introduction Metformin-associated lactic acidosis (MALA) is a classic side effect of metformin and is known to be a severe disease with a high mortality rate. The treatment of MALA with dialysis is controversial and is the subject of many case reports in the literature. We aimed to assess the prevalence of MALA in a 16-bed, university-affiliated, intensive care unit (ICU), and the effect of dialysis on patient outcome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
