Background: To evaluate the clinical features of patients with bloodstream infection (BSI).

Methods: Totally 200 inpatients with BSI were included, clinical features of BSI inpatients between 90-day survival and 90-day mortality groups, between 30-day survival and 30-day mortality groups, between patients infected with multidrug-resistant (MDR group) and sensitive (sensitive group) were analyzed. The prognostic factors of 90-day mortality were analyzed by univariate logistic regression and multivariate logistic regression. The survival curve in bloodstream infectious patients with multidrug-resistant (MDR group) and sensitive (sensitive group) was analyzed by Kaplan-Meier analysis.

Results: The 90-day mortality patients had significantly higher carbapenem-resistant bacterial infection and critical care unit (ICU) admission. The 90-day and 30-day mortality groups showed higher C-reactive protein (CRP) and serum creatinine (Scr) levels and lower red blood cells (RBC) and albumin (ALB) levels than their survival counterparts, respectively. Critical surgery, ICU admission and delayed antibiotic treatment were independently prognostic risk predictors for 90-day mortality in BSI patients, while critical surgery and diabetes were independently prognostic risk predictors for 90-day mortality in carbapenem-resistant BSI patients. Compared with sensitive group, MDR group showed significantly longer ICU and whole hospital stay, lower levels of lymphocytes, RBC, hemoglobin, lactate dehydrogenase and ALB, higher frequency of infection originating from the skin and skin structure. Moreover, patients in the MDR group had a significantly worse overall survival than the sensitive group.

Conclusion: We identified the prognostic factors of BSI and carbapenem-resistant BSI patients. Critical surgery, ICU admission, delayed antibiotic treatment or diabetes were significantly associated with the mortality of those patients. Moreover, aggressive measures to control MDR could lead to improved outcomes.

Background: Traumatic cervical spinal cord injury (cSCI) is a serious condition that requires a multidisciplinary treatment approach involving care at a neurotrauma center (NTC) and specialized rehabilitation. Contemporary population-based studies of cSCI are important for ensuring the quality and planning of health care approaches for these patients.

Methods: This is a population-based cohort study of patients with traumatic cSCI who were admitted to the NTC in Southeast Norway between 2015 and 2022.

Background: This study aims to address the timing of repair for severe congenital diaphragmatic hernia (CDH) without the use of extracorporeal membrane oxygenation (ECMO) and to determine the feasibility of an earlier intervention to avoid deaths associated with non-repair in patients who are more challenging to stabilize without ECMO.

Methods: This single-center retrospective study was conducted on neonates with CDH from 2013 to 2023. Based on the timing of surgery, the patients were classified into three groups: <24 hours (group A), 24-48 hours (group B) and ≥48 hours (group C).

Background: Ischemic stroke is a major contributor to global morbidity and mortality, particularly in critically ill patients in intensive care units (ICUs). While advances in stroke management have improved outcomes, predicting mortality remains challenging due to the involvement of complex metabolic and cardiovascular factors. The triglyceride-glucose (TyG) index, a marker for insulin resistance, has gained attention for its potential to predict adverse outcomes in stroke patients.
