The minimum Hb for blood donation varies from nation to nation. This study assessed the impact of blood donation on donors' iron stores based on different Hb levels. An estimation of drop in the blood collection was made with the new suggested Hb cut-off value. ⋯ A modification in the minimum Hb level for blood donation is necessary when Hb is used as the single criterion for screening donors. Increasing the minimum Hb level will lead to an increase in donor deferral; therefore a comprehensive donor retention program will be needed.

Randomized Controlled Trial
Effectiveness of oral Tranexamic acid administration on blood loss after knee artroplasty: a randomized clinical trial.
Some studies have proved that Tranexamic acid infusion is associated with a decrease in blood loss during and after surgery. Due to the availability of an oral form of the drug, the rapid and complete absorption of it and ease of administration without need for specific instruments, we evaluated the effectiveness of the oral form in decreasing blood loss after total knee arthroplasty. ⋯ Prescription of oral Tranexamic acid before knee arthroplasty can cause remarkable decrease in blood loss after surgery and also less decrease in hematocrit. The advantages of the oral route of the drug versus the intravenous form is that it can be used routinely as a safe and effective way to decrease bleeding after surgery.

Comparative Study
Comparison between two portable hemoglobinometers and a reference method to verify the reliability of screening in blood donors.
Portable hemoglobinometers are used to determine hemoglobin level, but there are conflicting reports regarding their accuracy. The aim of this study was to compare results from two portable hemoglobinometers (HemoCue® and Hemo-Control) with an automated hematology analyzer (Sysmex XE-2100D) to determine if the screening of blood donors is reliable. A total of 426 blood donors' samples were studied and on average the Hb content measured in capillary blood samples was higher than that found in venous blood samples. Hemoglobinometers can be employed as a method to screen blood donors, but critical values should be confirmed in an automated hematology analyzer.

The patients' hemodynamic conditions of septic shock due to intra-abdominal infection were improved by the longer duration of direct hemoperfusion with a polymyxin B-immobilized fiber column (PMX), reducing plasma endotoxins measured by the novel endotoxin detection method, named endotoxin scattering photometry (ESP) method; however, turbidimetric method could not detect endotoxins. We also observed the reduction in the endotoxin after passing through column by ESP method even after the longer duration of PMX. ESP method may more sensitively detect endotoxins than the ordinary turbidimetric method. Moreover, we demonstrated the ability of endotoxin adsorption in spite of the longer duration of PMX.

Due to the high transplant related morbidity and mortality (TRM), relatively younger acute leukemia patients that have a good performance status and no comorbidity are eligible for myeloablative conditioning (MAC) followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). The outcomes of 84 consecutive adult patients with ALL (n=38) or AML (n=46) who underwent allo-HSCT from their HLA-identical siblings were evaluated retrospectively. The median age at transplantation was 34 (17-58 years) for the whole patient population. ⋯ Eleven of the RIC patients (18.3%) and 6 of the MAC patients (25%) developed acute graft-versus-host disease (GvHD). Seventeen of the RIC patients (33.3%) and 4 of the MAC patients (16.7%) developed chronic GvHD. In conclusion, RIC conditioning regimens may provide a longer OS and DFS, especially in patients with AML who are in first CR, not eligible for MAC conditioning.
