RESUMEN

OBJECTIVES: This study assessed the impact of early postoperative organ dysfunction (EPOD) on in-hospital mortality of patients with type A aortic dissection (TAAD) after surgery. METHODS: Patients with TAAD who underwent surgical repair requiring deep hypothermic circulatory arrest from January 2020 to December 2021 were included. The Sequential Organ Failure Assessment (SOFA) score was calculated for 3 days postoperatively to stratify the severity of organ dysfunction. Patients with the SOFA of 0-4, 5-8 or >8 were defined as mild, moderate or severe EPOD. The primary outcome was in-hospital mortality, and a composite secondary outcome was defined as in-hospital death or any major complications. Kaplan-Meier curves were used to compare survival probability. The area under the receiver operating characteristic curve and calibration plots were used to evaluate the predictive power and overall performance of SOFA. RESULTS: Of the 368 patients, 5 patients (3%) with moderate EPOD and 33 patients (23%) with severe EPOD died. No patient died with mild EPOD. The areas under the receiver operating characteristic curve of SOFA for predicting mortality and the composite outcome were 0.85 (0.81-0.88) and 0.81 (0.77-0.85) on postoperative day 1. Each point of postoperative day 1 SOFA score corresponded to an odds ratio of 1.65 (1.42-1.92) for mortality. Of the 6 components of the SOFA system, only coagulation (2.34 [1.32-4.13]), cardiovascular (1.47 [1.04-2.08]), central nervous system (1.96 [1.36-2.82]) and renal (1.67 [1.04-2.70]) functions were associated with the higher risk of mortality. CONCLUSIONS: EPOD stratified by the SOFA score was associated with a higher risk of death and predicted the clinical outcomes of patients with TAAD with good accuracy.

RESUMEN

BACKGROUND: Severe accidental hypothermia (AH) is life threatening. Thus, prognostic prediction in AH is essential to rapidly initiate intensive care. Several studies on prognostic factors for AH are known, but none have been established. We clarified the prognostic ability of the Sequential Organ Failure Assessment (SOFA) score in comparison with previously reported prognostic factors among patients with AH. METHODS: The J-point registry database is a multi-institutional retrospective cohort study for AH in 12 Japanese emergency departments. From this registry, we enrolled patients who were treated at the intensive care unit (ICU) in various critical care medical centers. In-hospital mortality was the primary outcome. We investigated the discrimination ability of each candidate prognostic factor and the in-hospital mortality by applying the logistic regression models with areas under the receiver operating characteristic curve (AUROC) with 95% confidence interval (CI). RESULTS: Of the 572 patients with AH registered in the J-point registry, 220 were eligible for the analyses. The in-hospital mortality was 23.2%. The AUROC of the SOFA score (0.80; 95% CI: 0.72-0.86) was the highest among all factors. The other factors were serum potassium (0.65; 95% CI: 0.55-0.73), lactate (0.67; 95% CI: 0.57-0.75), quick SOFA (qSOFA) (0.55; 95% CI: 0.46-0.65), systemic inflammatory response syndrome (SIRS) (0.60; 95% CI: 0.50-0.69), and 5A severity scale (0.77; 95% CI: 0.68-0.84). DISCUSSION: Although serum potassium and lactate had relatively good discrimination ability as mortality predictors, the SOFA score had slightly better discrimination ability. The reason is that lactate and serum potassium were mainly reflected by the hemodynamic state; conversely, the SOFA score is a comprehensive score of organ failure, basing on six different scores from the respiratory, cardiovascular, hepatic, coagulation, renal, and neurological systems. Meanwhile, the qSOFA and SIRS scores underestimated the severity, with low discrimination abilities for mortality. CONCLUSIONS: The SOFA score demonstrated better discrimination ability as a mortality predictor among all known prognostic factors in patients with AH.

RESUMEN

INTRODUCTION: Burkholderia cepacia complex (Bcc) is non-fermenting Gram-negative bacillus and has been rarely reported to cause spontaneous bacterial peritonitis (SBP) in decompensated cirrhosis. OBJECTIVE: This study was done to evaluate the clinical presentation of cirrhotic patients with SBP due to Bcc and to determine its impact on clinical outcome. METHODS: This is a retrospective, observational study conducted during the period from 1st January 2013 through 31st March 2015. Medical records and microbiology laboratory files were reviewed to identify all cases of Bcc associated SBP among patients hospitalized at the liver intensive care unit and analyzed. RESULTS: During the study period, out of 252 SBP patients, 11 (4.3%) patients with a positive ascitic fluid culture for Bcc were identified. Pain abdomen was the predominant symptom present in 9 (81%) patients followed by hepatic encephalopathy in 7 (63%) patients. Acute kidney injury (AKI) was universally present, seen in 6 (54%) patients at the time of presentation and 4 (36%) patients developed AKI during hospital stay. The mean CTP score was 11.2 ± 1.1 (10-13), and the mean MELD was 24.3 ± 5.9 (14-35). The mean SOFA and APACHE II score at presentation were 11 ± 4.2 (4-18) and 19.4 ± 5.2 (11-28), respectively. A total of 8 (72%) patients (6-ACLF, 2-NASH) succumbed to the illness during hospitalization due to severe sepsis and multiorgan dysfunction and 3 (27%) patients are doing well on follow-up after 3 months. CONCLUSION: SBP caused by Bcc has been rarely reported in cirrhotic patients. This organism is intrinsically resistant to third generation cephalosporins, which are the initial antibiotic of choice for SBP patients, hence associated with multi organ failure and high mortality rates.
