Meta Analysis Comparative Study
A Systematic Review and Meta-analysis of Randomized Controlled Trials Comparing Intraoperative Red Blood Cell Transfusion Strategies.
The objective of this work was to carry out a meta-analysis of RCTs comparing intraoperative RBC transfusion strategies to determine their impact on postoperative morbidity, mortality, and blood product use. ⋯ Intraoperative restrictive transfusion strategies decreased perioperative transfusions without added postoperative morbidity and mortality in 12/14 trials. Two trials reported worse outcomes. Given trial design and generalizability limitations, uncertainty remains regarding the safety of broad application of restrictive transfusion triggers in the operating room. Trials specifically designed to address intraoperative transfusions are urgently needed.

To perform a scoping review of imaging-based machine-learning models to predict clinical outcomes and identify biomarkers in patients with PDAC. ⋯ The use of imaging-based machine-learning models to predict clinical outcomes and identify biomarkers in patients with PDAC is increasingly rapidly. Although these models mostly have good performance scores, their methodological quality should be improved.

Meta Analysis Comparative Study
Chemoradiotherapy followed by Active Surveillance Versus Standard Esophagectomy for Esophageal Cancer: A Systematic Review and Individual Patient Data Meta-Analysis.
To compare overall survival of patients with a cCR undergoing active surveillance versus standard esophagectomy. ⋯ Overall survival was comparable in patients with cCR after chemoradiotherapy undergoing active surveillance or standard esophagectomy. Diagnostic follow-up is mandatory in active surveillance and postponed esophagectomy should be offered to operable patients in case of locoregional recurrence.

To survey the available literature regarding the use of auxiliary liver transplantation (ALT) in the setting of cirrhosis. ⋯ Two-stage LT and, more recently, the RAPID procedure are viable options for increasing the number of transplantations for cirrhotic patients by using small grafts.
