AI Article Synopsis
- Strategies for blood conservation and preoperative assessment can be beneficial for Jehovah's Witness patients undergoing cardiac surgery, necessitating an evaluation of safety and clinical outcomes in these cases.
- A systematic review and meta-analysis of 10 studies involving 2,302 patients indicated no significant differences in short-term mortality between Jehovah's Witness patients and controls after cardiac surgery.
- JW patients demonstrated higher preoperative hemoglobin levels and slightly lower cardiopulmonary bypass times, suggesting that bloodless cardiac surgery can be safe and effective with proper patient management.
Article Abstract
Background: Strategies for blood conservation, coupled with a careful preoperative assessment, may be applied to Jehovah's Witnesses (JW) patients who are candidates for cardiac surgery interventions. There is a need to assess clinical outcomes and safety of bloodless surgery in JW patients undergoing cardiac surgery.
Methods: We performed a systematic review and meta-analysis of studies comparing JW patients with controls undergoing cardiac surgery. The primary endpoint was short-term mortality (in-hospital or 30-day mortality). Peri-procedural myocardial infarction, re-exploration for bleeding, pre-and postoperative Hb levels and cardiopulmonary bypass (CPB) time were also analyzed.
Results: A total of 10 studies including 2,302 patients were included. The pooled analysis showed no substantial differences in terms of short-term mortality among the two groups (OR 1.13, 95% CI 0.74-1.73, I=0%). There were no differences in peri-operative outcomes among JW patients and controls (OR 0.97, 95% CI 0.39-2.41, I=18% for myocardial infarction; OR 0.80, 95% CI 0.51-1.25, I=0% for re-exploration for bleeding). JW patients had a higher level of preoperative Hb (Standardized Mean Difference [SMD] 0.32, 95% CI 0.06-0.57) and a trend toward a higher level of postoperative Hb (SMD 0.44, 95% CI -0.01-0.90). A slightly lower CPB time emerged in JWs compared with controls (SMD -0.11, 95% CI -0.30-0.07).
Conclusions: JW patients undergoing cardiac surgery, with avoidance of blood transfusions, did not have substantially different peri-operative outcomes compared with controls, with specific reference to mortality, myocardial infarction, and re-exploration for bleeding. Our results support the safety and feasibility of bloodless cardiac surgery, applying patient blood management strategies.

Objective: To study the effectiveness of virtual reality (VR) in reducing anxiety levels in patients undergoing first-time sternotomy for cardiac surgery.
Patients And Methods: A total of 100 adult patients scheduled for cardiac surgery at Mayo Clinic in Rochester, Minnesota, USA, was recruited from April 19, 2022, to October 12, 2022. Before surgery, patients wore a physiological monitor to record vital signs.

Inherited genetics represents an important contributor to risk of esophageal adenocarcinoma (EAC), and its precursor Barrett's esophagus (BE). Genome-wide association studies have identified ∼30 susceptibility variants for BE/EAC, yet genetic interactions remain unexamined. To address challenges in large-scale G×G scans, we combined knowledge-guided filtering and machine learning approaches, focusing on genes with (A) known/plausible links to BE/EAC pathogenesis (n=493) or (B) prior evidence of biological interactions (n=4,196).
