In this study, we hypothesized that a moderate perioperative mean blood glucose level of<150mg/dL improves long-term survival in cardiac surgery patients. We conducted a prospective, observational cohort study in the heart center of the University Medical Center of Goettingen, Germany. Patients undergoing on-pump cardiac surgery were enrolled in this investigation. After evaluating perioperative blood glucose levels, patients were classified into 2 groups based on mean glucose levels: Glucose 150mg/dL and Glucose<150mg/dL. Patients were followed up for 5 years, and mortality within this period was recorded as the primary outcome parameter. Secondary outcome parameters included the length of ICU stay, the use of inotropic agents, the length of hospital stay, and the in-hospital mortality. A total of 455 consecutive patients who underwent cardiac surgery with cardiopulmonary bypass were enrolled in this investigation. A Kaplan-Meier survival analysis of the 5-year mortality risk revealed a higher mortality risk among patients with glucose levels 150mg/dL (P=0.0043, log-rank test). After adjustment for confounders in a multivariate Cox regression model, the association between glucose 150mg/dL and 5-year mortality remained significant (hazard ratio, 2.10; 95% CI, 1.30-3.39; P=0.0023). This association was corroborated by propensity score matching, in which Kaplan-Meier survival analysis demonstrated significant improvement in the 5-year survival of patients with glucose levels<150mg/dL (P=0.0339). Similarly, in-hospital mortality was significantly higher in patients with glucose 150mg/dL compared with patients with glucose<150mg/dL. Moreover, patients in the Glucose 150mg/dL group required significantly higher doses of the inotropic agent Dobutamine (mg/d) compared with patients in the Glucose<150mg/dL group (20.6 +/- 62.3 and 10.5 +/- 40.7, respectively; P=0.0104). Moreover, patients in the Glucose 150mg/dL group showed a significantly longer hospital stay compared with patients in the Glucose<150mg/dL group (28 +/- 23 and 24 +/- 19, respectively; P=0.0297).

Statins are expected to attenuate inflammation in the lungs of patients with ARDS due to their anti-inflammatory effects. Clinical investigations of the role of statin therapy have revealed contradictory results. This study aimed to investigate whether pretreatment and continuous therapy with statins in patients with sepsis-associated ARDS are associated with 28-day survival according to disease severity (mild, moderate, or severe). Methods: Patients with sepsis-associated ARDS from the surgical intensive care were enrolled in this prospective observational investigation. ARDS was classified into three groups (mild, moderate, and severe); 28-day mortality was recorded as the primary outcome variable and organ failure was recorded as secondary outcome variable. Sequential Organ Failure Assessment scores and the requirements for organ support were evaluated throughout the observational period to assess organ failure. Results: 404 patients with sepsis-associated ARDS were enrolled in this investigation. The distribution of the ARDS subgroups was 13 %, 59 %, and 28 % for mild, moderate, and severe disease, respectively. Statin therapy improved 28-day survival exclusively in the patients with severe ARDS compared with patients without statin therapy (88.5 % and 62.5 %, respectively; P = 0.0193). To exclude the effects of several confounders, we performed multivariate Cox regression analysis, which showed that statin therapy remained a significant covariate for mortality (hazard ratio, 5.46; 95 % CI, 1.38-21.70; P = 0.0156). Moreover, after carrying a propensity score-matching in the severe ARDS cohort, Kaplan-Meier survival analysis confirmed the improved 28-day survival among patients with statin therapy (P = 0.0205). Patients with severe ARDS who received statin therapy had significantly more vasopressor-free days compared with those without statin therapy (13 +/- 7 and 9 +/- 7, respectively; P = 0.0034), and they also required less extracorporeal membrane oxygenation (ECMO) therapy and had more ECMO-free days (18 +/- 9 and 15 +/- 9, respectively; P = 0.0873).

In this study, we hypothesized that the strong pro-inflammatory response induced by the TT genotype of CD14 rs2569190 may have a beneficial effect on survival (30-day) in patients with sepsis.

Sepsis-related organ failure assessment (SOFA) scores were quantified at sepsis onset and throughout the observational period to monitor organ failure as a secondary variable. Moreover, organ support-free days were evaluated as a secondary outcome parameter. TT-homozygous patients were compared to C-allele carriers. Kaplan-Meier survival analysis revealed a higher 30-day mortality risk among C-allele carriers compared with T homozygotes (p = 0.0261).

Design: Prospective, observational cohort study. Setting: Three surgical intensive care units (ICUs) at a university medical centre. Participants: A total of 327 adult Caucasian patients with sepsis originating from pulmonary, intra-abdominal and primary bacteraemia participated in this study. Primary and secondary outcome measures: The patients were followed for 90 days and mortality risk was recorded as the primary outcome variable. To monitor organ failure, sepsis-related organ failure assessment (Sequential Organ Failure Assessment, SOFA) scores were evaluated at the onset of sepsis and throughout the observational period as secondary outcome variables. Results: A total of 327 critically ill patients with sepsis were enrolled in this study. Kaplan-Meier survival analysis showed that the 90-day mortality risk was significantly higher among patients with primary bacteraemia than among those with pulmonary and intra-abdominal foci (58%, 35% and 32%, respectively; p=0.0208). To exclude the effects of several baseline variables, we performed multivariate Cox regression analysis. Primary bacteraemia remained a significant covariate for mortality in the multivariate analysis (HR 2.10; 95% CI 1.14 to 3.86; p=0.0166). During their stay in the ICU, the patients with primary bacteraemia presented significantly higher SOFA scores than those of the patients with pulmonary and intra-abdominal infection foci (8.5 +/- 4.7, 7.3 +/- 3.4 and 5.8 +/- 3.5, respectively). Patients with primary bacteraemia presented higher SOFA-renal score compared with the patients with other infection foci (1.6 +/- 1.4, 0.8 +/- 1.1 and 0.7 +/- 1.0, respectively); the patients with primary bacteraemia required significantly more renal replacement therapy than the patients in the other groups (29%, 11% and 12%, respectively).
