AI Article Synopsis
- In elderly hip fracture patients, preexisting anemia can worsen due to trauma and surgery, creating uncertainty around blood transfusion thresholds.
- A study analyzed hemoglobin and hematocrit levels in 956 surgical patients with proximal femoral fractures to determine transfusion triggers and their impact on post-discharge mortality.
- Results indicated higher transfusion rates and mortality among those with lower hemoglobin levels, suggesting a need for reevaluation of preoperative blood transfusion protocols, while cautioning that increasing thresholds might lead to higher mortality rates.
Article Abstract
In hip fracture patients, who are mostly elderly, preexisting anemia can be worsened when combined with trauma and surgery. To this date, there is no unequivocal approach about transfusion thresholds. We analyzed hemoglobin (Hb) and hematocrit (Hct) levels at three time points in surgical patients with proximal femoral fractures (PFF) to see which levels were triggers for transfusions and whether transfusions were related to mortality after hospital discharge. A total of 956 patients were operated on from 1 January 2021 to 31 December 2022 at the University Hospital of Split and included in the study. There were more women (74%); 47% patients had admission Hb < 120 g/L. Transfusion was given preoperatively to 88, intraoperatively to 74 and postoperatively to 309 patients. Transfusion thresholds were as follows: Hb 84 g/L preoperatively, 99 intraoperatively and 83 postoperatively. After hospital discharge, 10.79% of patients died within the 1st month and 23% within 6 months. In the group of non-survivors, 60% of patients had admission Hb ≤ 117 g/L and the proportion of patients transfused preoperatively was two times higher. Preoperative transfusion thresholds could be set to higher levels for patients with surgically treated PFF. However, that could increase mortality even more. Further investigation is necessary.

Evaluation of point-of-care haemoglobin measurement accuracy in surgery (PREMISE) and implications for transfusion practice: a prospective cohort study.
Br J Anaesth

Background: Point-of-care testing devices to measure haemoglobin (Hgb) frequently inform transfusion decision-making in surgery. This study aimed to examine their accuracy in surgery, focusing on Hgb concentrations of 60-100 g L, a range with higher potential for transfusion.
Methods: This was a prospective diagnostic cohort study focused on method comparison, conducted at two academic hospitals.
Donor Specific Antibodies in Extracorporeal Membrane Oxygenation-Bridged Lung Transplant Recipients.
Ann Thorac Surg Short Rep

Department of Pulmonary and Critical Care Medicine, University of Pennsylvania, Philadelphia, Pennsylvania.
Background: Extracorporeal membrane oxygenation (ECMO) is increasingly used as a bridge to lung transplantation. Although other mechanical circulatory support devices have been associated with anti-human leukocyte antigen antibody formation, including de novo donor-specific antibodies (dnDSA), it is unknown whether ECMO is a sensitizing exposure.
Methods: This was a single-center retrospective cohort study of lung transplant recipients.
Restrictive or Liberal Blood Transfusion in Patients with Myocardial Infarction and CKD.
J Am Soc Nephrol

Rutgers Robert Wood Johnson Medical School, New Brunswick, NJ, USA.
Background: Chronic kidney disease (CKD) is associated with higher risk of myocardial infarction and anemia. Among patients with anemia and CKD who experience myocardial infarction, it remains uncertain if a liberal red blood cell transfusion threshold strategy (hemoglobin cutoff [Hgb] < 10 g/dL) is superior to a restrictive transfusion threshold (Hgb 7-8 g/dL) strategy.
Methods: Among the 3,504 patients enrolled in the Myocardial Ischemia and Transfusion (MINT) trial with non-missing creatinine, we compared baseline characteristics and 30-day and 6-month outcomes of patients without CKD (N = 1279), CKD with eGFR 30-60 mL/min/1.
In Vivo Induction of Leukemia-Specific Adaptive and Innate Immune Cells by Treatment of AML-Diseased Rats and Therapy-Refractory AML Patients with Blast Modulating Response Modifiers.

There is a high medical need to develop new strategies for the treatment of patients with acute myeloid leukemia (AML) refractory to conventional therapy. In vitro, the combinations of the blast-modulatory response modifiers GM-CSF + Prostaglandin E1, (summarized as Kit M) have been shown to convert myeloid leukemic blasts into antigen-presenting dendritic cells of leukemic origin (DC) that were able to (re-)activate the innate and adaptive immune system, direct it specifically against leukemic blasts, and induce memory cells. This study aimed to investigate the immune modulatory capacity and antileukemic efficacy of Kit M in vivo.
