ABSTRACT

BACKGROUND: Extracorporeal circulation auxiliary to open heart surgery is a common procedure used to treat heart diseases. However, the optimal transfusion strategy for patients undergoing this surgery remains a subject of debate. This study aims to investigate the association between hemoglobin levels and clinical outcomes in patients undergoing extracorporeal circulation auxiliary to open heart surgery, with the ultimate goal of improving surgical success rates and enhancing patients' quality of life. METHODS: A retrospective analysis was conducted on data from the Medical Information Mart for Intensive Care IV 2.2 (MIMIC-IV 2.2) database, including 4144 patients. The patients were categorized into five groups based on their minimum hemoglobin levels during hospitalization. Baseline characteristics, clinical scores, laboratory results, and clinical outcome data were collected. Statistical analyses utilized descriptive statistics, ANOVA or Kruskal-Wallis tests, Kaplan-Meier method, and Log-rank test. RESULTS: The results revealed a significant correlation between hemoglobin levels and in-hospital mortality, as well as mortality rates at 30 days, 60 days, and 180 days (p < 0.001). Patients with lower hemoglobin levels exhibited higher mortality rates. However, once hemoglobin levels exceeded 7g/dL, no significant difference in mortality rates was observed (p = 0.557). Additionally, lower hemoglobin levels were associated with prolonged hospital stay, ICU admission time, and mechanical ventilation time (p < 0.001). Furthermore, hemoglobin levels were significantly correlated with complication risk, norepinephrine dosage, and red blood cell transfusion volume (p < 0.001). However, there was no significant difference among the groups in terms of major complications, specifically sepsis (p > 0.05). CONCLUSION: The study highlights the importance of managing hemoglobin levels in patients undergoing heart surgery with extracorporeal circulation. Hemoglobin levels can serve as valuable indicators for predicting clinical outcomes and guiding treatment decisions. Physicians should carefully consider hemoglobin levels to optimize transfusion strategies and improve postoperative patient outcomes. Further research and intervention studies are warranted to validate and implement these findings in clinical practice.

ABSTRACT

BACKGROUND: Pancreatic cancer is one of the most aggressive malignancies and chemotherapy is an effective strategy for advanced pancreatic cancer. Gemcitabine (GEM) is one of first-line agents. However, GEM-based combination therapy has shown promising efficacy in patients with advanced pancreatic cancer. This meta-analysis aimed to compare the efficacy and safety of GEM-based combination therapy versus GEM alone in the treatment of advanced pancreatic cancer. DATA SOURCES: A comprehensive search of literature was performed using PubMed, EMBASE, Web of Science and Cochrane Central Register of Controlled Trials. A quantitative meta-analysis was performed based on the inclusion criteria from all eligible randomized controlled trials. The outcome indicators included overall survival (OS), 6-month survival, 1-year survival, progression-free survival/time-to-progression (PFS/TTP), and toxicities. RESULTS: A total of nine randomized controlled trials involving 1661 patients were included in this meta-analysis. There was significant improvement in the GEM-based combination therapy with regard to the OS (HR=0.85, 95% CI: 0.76-0.95, P=0.003), PFS (HR=0.76, 95% CI: 0.65-0.90, P=0.002), 6-month survival (RR=1.09, 95% CI: 1.01-1.17, P=0.03), and the overall toxicity (RR=1.68, 95% CI: 1.52-1.86, P<0.01). However, there was no significant difference in the 1-year survival. CONCLUSIONS: GEM-based combination chemotherapy might improve the OS, 6-month survival, and PFS in advanced pancreatic cancer. However, combined therapy also added toxicity.
