ABSTRACT
Background/Aims@#Maintaining a mean arterial pressure (MAP) ≥ 65 mmHg during septic shock should be based on individual circumstances, but specific target is poorly understood. We investigated associations between time-weighted average (TWA) hemodynamic parameters during the initial resuscitative period and 28-day mortality. @*Methods@#Prospectively collected data were obtained from a septic shock patient registry, according to the Sepsis-3 definition, between 2016 and 2018. The TWA systolic blood pressure, diastolic blood pressure, MAP, shock index, and pulse pressure (PP) during the first 6 hours after shock recognition were compared. Multivariable regression analysis was performed to assess associations between these parameters and 28-day mortality. @*Results@#Of 340 patients with septic shock, 92 died. Only the median TWA PP differed between the survivors and non-survivors (39.2 mmHg vs. 43.0 mmHg, p = 0.020), whereas the other indexes did not. When PP was divided into quartiles ( 48 mmHg), the mortality rate was higher in the highest quartile (41.2%). Multivariable logistic analysis revealed that PP (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.012 to 1.622; p = 0.039) and PP of > 48 mmHg (OR, 2.25; 95% CI, 1.272 to 3.981; p = 0.005) were independently associated with 28-day mortality. @*Conclusions@#PP was significantly associated with 28-day mortality in patients with septic shock and MAP maintained at > 65 mmHg during the first 6 hours. Further studies are warranted to optimize strategies for maintaining PP and MAP at > 65 mmHg during the early resuscitative period.

ABSTRACT
OBJECTIVE@#This study assessed whether characteristics of ruptured hepatocellular carcinoma (HCC) at presentation to the emergency department (ED) affect patient outcomes, and evaluated factors prognostic of HCC, particularly treatment modalities.@*METHODS@#This retrospective study between 2008 and 2017 evaluated patients presenting to an ED with ruptured HCC. Parameters associated with 30- and 90-day mortality were investigated, and clinical characteristics and treatments were analyzed.@*RESULTS@#In total, 121 patients presented to the ED with ruptured HCC. Of these, 29 died within 30 days. Multivariate logistic regression analysis showed that platelet count (odds ratio [OR], 0.98; 95% confidence interval [CI], 0.976–0.995) and prothrombin time (OR, 16.20; 95% CI, 1.91–137.23) were associated with a 30-day mortality rate, whereas presence or absence of acute abdominal pain and shock at presentation to the ED was not significant. Patients who underwent embolization had a lower 30-day mortality rate than those treated conservatively (OR, 0.04; 95% CI, 0.001-0.20). Sixtyone patients died within 90 days after presentation to the ED. Serum albumin concentration (OR, 0.25; 95% CI, 0.09–0.71) was associated with 90-day mortality. Moreover, patients who underwent embolization (OR, 0.19; 95% CI, 0.06–0.60) and emergency hepatectomy (OR 0.09; 95% CI, 0.01–0.99) had lower 90-day mortality rates as compared to patients treated conservatively.@*CONCLUSION@#Presence of acute abdominal pain at presentation to the ED does not affect patient outcomes. Early aggressive treatments, such as embolization or emergency hepatectomy, were observed to improve outcomes in patients with ruptured HCC.
