Introduction: Traumatic brain injury (TBI) has become a significant cause of death and morbidity in childhood since the elucidation of infectious causes within the last century. Mortality rates in this population decreased over time due to developments in technology and effective treatment modalities.
Aim of the study: This retrospective cohort study aimed to describe the volume, severity and mechanism of all hospital-admitted pediatric TBI patients at a university hospital over a 5-year period. Material and
Methods: This was a single-center, retrospective cohort study including 90 pediatric patients with TBI admitted to a tertiary care PICU. The patients’ demographic data, injury mechanisms, disease and trauma severity scores, initiation of enteral nutrition and outcome measures such as hospital stay, PICU stay, duration of mechanical ventilation, mortality, and Glasgow Outcome Scale (GOS) were also recorded. Late enteral nutrition was defined as initiation of enteral feeding after 48 hours of hospitalization.
Results: Of the 90 patients included in the cohort, 60% had mild TBI, 21.1% had moderate TBI and 18.9% had severe TBI. Their mean age was 69 months (3-210 months). TBI was isolated in 34 (37.8%) patients and observed as a part of multisystemic trauma in 56 (62.2%). The most commonly involved site in multisystemic injury was the thorax (33.3%). The length of hospitalization in the late enteral nutrition group was significantly higher than that in the early nutrition group, while the PICU stay was not significantly different between the two groups. The multiple logistic regression analysis found a significant relationship between GOS-3rd month and PIM3 score, the presence of diffuse axonal injury and the need for CPR in the first 24 h of hospitalization.
Conclusion: Although our study showed that delayed enteral nutrition did not affect neurologic outcome, it may lead to prolonged hospitalization and increased hospital costs. High PIM3 scores and diffuse axonal injury are both associated with worse neurologic outcomes.

Background: Single lactate measurements have been reported to have prognostic significance, however, there is a lack of data in local literature from Pakistan. This study was done to determine prognostic role of lactate clearance in sepsis patients being managed in our lower-middle income country.
Methods: This prospective cohort study was conducted from September 2019-February 2020 at the Aga Khan University Hospital, Karachi. Patients were enrolled using consecutive sampling and categorized based on their lactate clearance status. Lactate clearance was defined as decrease by 10% or greater in repeat lactate from the initial measurement (or both initial and repeat levels <=2.0 mmol/L).
Results: A total 198 patients were included in the study, 51% (101) were male. Multi-organ dysfunction was reported in 18.6% (37), 47.7% (94) had single organ dysfunction, and 33.8% (67) had no organ dysfunction. Around 83% (165) were discharged and 17% (33) died. There were missing data for 25.8% (51) of the patients for the lactate clearance, whereas 55% (108) patients had early lactate clearance and 19.7% (39) had delayed lactate clearance.On univariate analysis, mortality rate was higher in patients with delayed lactate clearance (38.4% vs 16.6%) and patients were 3.12 times (OR = 3.12; [95% CI: 1.37-7.09]) more likely to die as compared with early lactate clearance. Patients with delayed lactate clearance had higher organ dysfunction (79.4% vs 60.1%) and were 2.56 (OR = 2.56; [95% CI: 1.07-6.13]) times likely to have organ dysfunction. On multivariate analysis, after adjusting for age and co-morbids, patients with delayed lactate clearance were 8 times more likely to die than patients with early lactate clearance [aOR = 7.67; 95% CI:1.11-53.26], however, there was no statistically significant association between delayed lactate clearance [aOR = 2.18; 95% CI: 0.87-5.49)] and organ dysfunction.
Conclusion: Lactate clearance is a better determinant of sepsis and septic shock effective management. Early lactate clearance is related to better outcomes in septic patients.
