Objective:Trauma scores are prone to misreading. Therefore, a readily available, objective way to estimate the mortality of the trauma patients is needed. We aimed to evaluate the prognostic utility of lactate levels, and clearance for 30-days mortality, and compare with the physiological trauma scores.Methods:All adult trauma patients (two hundred) admitted to ED were enrolled. Initial and 2-hour serum lactate levels were measured and components of GAP, MGAP, RTS, VIEWS and VIEWS-L trauma scores were calculated.Results:Final study population was 200 patients with a median age of 33 years. Mortality was 7/200 (3.5%) in 30-days. Both initial (2.3 vs. 7.7 mmol/L) and 2h-lactate (1.7 vs. 8.4 mmol/L) levels were significantly lower, and lactate clearance was significantly higher (23.8% vs. -12.0%) in survivors. Also, the change in the lactate level from 0h to 2h (2.3 vs. 1.7mmol/L) was significant in survivors, contrary to non-survivors (7.7 vs. 8.4mmol/L). VIEWS-L, VIEWS, two hour-lactate level and EMTRAS showed high specificity at the 100% sensitivity cut-offs, therefore, were the most valuable prognostic parameters in this study.Conclusion:Calculation of 2h-lactate clearance and evaluation of a 2h-lactate level may not be needed to predict long-term mortality if the initial lactate level is below 2.8mmol/L.

Objective: To investigate the association of C-reactive protein and procalcitonin with commonly used prognostic scoring systems, hospitalisation and mortality in cases of community-acquired pneumonia. Methods: The prospective study was conducted from April 2014 to April 2015 at the emergency department of Marmara University Pendik Research and Training Hospital,Turkey, and comprised community-acquired pneumonia patients diagnosed according to the British Thoracic Society criteria. Prognosis was estimated using confusion, urea, respiratory rate, blood pressure and age ?65, Pneumonia Severity Index-Pneumonia Patient Outcome Research Team score, and severe community-acquired pneumonia scores. Data was analysed using MedCalc 15.8. Results: Of the 203 patients assessed, community-acquired pneumonia was confirmed in 152(74.8%). Procalcitonin had moderate correlation with the three scales used (p<0.001), while C-reactive protein had weak correlation with them (p<0.004). Conclusion: Both procalcitonin and C-reactive protein levels were found to be correlated with prognostic risk scores. Key Words: Pneumonia, C reactive protein, procalcitonin, Continuous...
