Background
Stenotrophomonas maltophilia has been increasingly recognized as an opportunistic pathogen associated with high morbidity and mortality. Data on the prognostic factors associated with S. maltophilia pneumonia in patients admitted to intensive care unit (ICU) are lacking.
Methods
We conducted a retrospective analysis of data from 117 patients with S. maltophilia pneumonia admitted to the ICUs of two tertiary referral hospitals in South Korea between January 2011 and December 2022. To assess risk factors associated with in-hospital mortality, multivariable logistic regression analyses were performed.
Results
The median age of the study population was 71 years. Ventilator-associated pneumonia was 76.1% of cases, and the median length of ICU stay before the first isolation of S. maltophilia was 15 days. The overall in-hospital mortality rate was 82.1%, and factors independently associated with mortality were age (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.00–1.09; P=0.046), Sequential Organ Failure Assessment (SOFA) score (OR, 1.21; 95%; CI, 1.02–1.43; P=0.025), corticosteroid use (OR, 4.19; 95% CI, 1.26–13.91; P=0.019), and polymicrobial infection (OR, 95% CI 0.07–0.69). However, the impact of appropriate antibiotic therapy on mortality was insignificant. In a subgroup of patients who received appropriate antibiotic therapy (n=58), antibiotic treatment modality-related variables, including combination or empirical therapy, also showed no significant association with survival.
Conclusions
Patients with S. maltophilia pneumonia in ICU have high mortality rates. Older age, higher SOFA score, and corticosteroid use were independently associated with increased in-hospital mortality, whereas polymicrobial infection was associated with lower mortality. The effect of appropriate antibiotic therapy on prognosis was insignificant.

Abstract PDF: BACKGOUND: The barrier can be altered by a number of insults to the brain (e.g., hypertension, freezing, trauma, drug). But the effect of the blood brain barrier distruction immediately after the neural change is unknown. In the present study, we focused on the BBBD after cervical sympathetic chain block.
METHODS
13 male Sprague-Dawley rats were divided into 2 groups. Group 1 (N=7) was blocked with 0.5% bupivacaine on the right cervical sympathetic chain and group 2 (N=6) was blocked with 0.5% bupivacaine on the bilateral cervical sympathetic chain. All rats received 37degrees C, 25% mannitol (1.75 g/kg) via right carotid artery and then, the effect of cervical sympathetic chain block on blood-brain barrier disruption of four cerebral compartment using 99mTc-human serum albumin and Evans blue was evaluated.
RESULTS
Both groups showed blood-brain barrier disruption and there was no significant difference between group 1 and group 2 in the anterior and posterior hemisphere of the right side brain. But group 2 showed significant blood-brain barrier disruption than group 1 in anterior and posterior hemisphere of the left brain (p<0.01).
CONCLUSIONS
This results suggest that cervical sympathetic chain block can increase the degree of mannitol-induced blood-brain barrier disruption via neural arch or blood flow change.
