Abstract
Background
Increasing blood supply safety is one of the most important goals of blood services in the world. In this study, we reviewed the prevalence rate and the trends of three main infections in whole blood donations and strategies for improving blood safety in Yazd blood transfusion center, Iran.
Materials and Methods
In this cross sectional study, data on hepatitis B, C and HIV infection were extracted from Iranian Donor Database of blood donation from 2004 to 2010 in Yazd province. All donors with positive confirmatory test were included. The data was analyzed by SPSS software due to demographic factors.
Results
The prevalence rate of hepatitis B, C and HIV infection decreased during these years (From 0.37%,
0.14% and 0 percent in 2004 to 0.14%, 0.05% and 0 in 2010, respectively). Both hepatitis B and C infections were significantly more in first-time blood donors with BSc or BA educational level. The prevalence rate of hepatitis B was significantly higher in donors with less than 20 year-old and female donors. The prevalence rate of hepatitis C was higherin30-39 age group (P-value=0.014).
Conclusion
The results showed that the strategies used for improving blood safety were efficient. Increasing public knowledge on blood-borne infections and their routes of transmission, importance of donating blood only by healthy donors are necessary to have a safe blood supply in future.

Abstract
Abstract Background Multiple transfusions in thalassemia patients may lead to antibody production against blood group antigens and hemolytic transfusion reaction might occur. In this study, antibody screening test was performed by tube and gel methods to determine the prevalence and specificity of alloantibodies in thalassemia patients. Materials and Methods In this cross-sectional study, overall of 100 thalassemia patients from Yazd thalassemia clinic were recruited from July to September 2013. Two blood samples with volume of 6 ml were collected from each patient for standard tube and gel method antibody screening tests and a questionnaire consisting of demographic, health and blood transfusion status was completed. Results Out of 100 cases, 54 were female (54%) and 46 male (46%). The patients' age mean was 14.97±7.91 years with 2 to 33 years age range. Only 4% (n=4) had developed alloantibodies. (One patient developed dual alloantibody (Anti-C and Anti-D) and three patients developed single alloantibody (Anti-K)).Gel method detected 4 patients with alloantibody but in two patients not detected by the standard tube method. Conclusion The prevalence of RBC alloantibody production in this study was less than most previous studies. Anti-K was the most prevalent alloantibody in thalassemia patients in Yazd. It seems Rh and Kell blood group phenotyping in a newly diagnosed thalassemia patient and selection of matched blood for transfusion is very important.

Abstract
Background: The brain and spinal cord tumors account for 15% to 20% of all childhood malignancies. It is important to know the epidemiologic characteristics and survival of these patients to better understand the disease and the factors affecting its prognosis. The aim pf this study was to characterize the clinicopathology and survival rate of childhood and adolescent brain and spinal cord tumors in center of Iran.
Materials and methods: This descriptive-analytic study was carried out using a retrospective cohort design. Thirty patients with brain and spinal cord tumors who referred to Shahid Sadoughi and Rahnemoon hospitals in Yazd from 2006 to 2016 and aged 1 to 18 years were evaluated. . The epidemiologic characteristics, survival, and the factors affecting the survival of brain and spinal cord tumors were investigated.
Results: The findings showed that between 30 studied patients, brain and spinal cord tumors were more common in males (19 males and 11 females). The average age of the patients was 8.60 ± 5.70 years. Fifteen (50%) patients survived. Seventeen (57%) patients were resident in Yazd province and 13 (43%) were from southern Iran. Twenty two patients (73.3%) had recurrence after recovery. The average of survival was 36 months, with an average of 27 months in females and 37 months in males. However, this difference was not significant. The most common tumor was gliomas. There was no significant relationship between the mean of survival with age, gender, geographical status, or type of treatment (P value> 0.05); however, there was a significant relationship between the year of tumor diagnosis and survival (P value=0.0134).
Conclusion: It seems that survival of the brain and spinal cord tumors in children and adolescence is a multifactor event and it is affected by various factors.
