    Introduction: The healthy, active, and receptive huge student population is potential blood donors to meet safe blood requirements. The study aimed to assess the current level of knowledge regarding blood donation of nursing students of the Faculty of Medicine & Health Sciences, UMS and to observe their attitude towards voluntary blood donation and to explore their practice as a voluntary blood donor. Methods: This cross-sectional study was con- ducted from July 2015 to June 2018 among one hundred and eight (108) nursing students who were included in this study by simple random sampling. The researchers explained the study design, objectives, and methodology to the selected subjects and obtained written consent from them. The study assessed the current level of knowledge and observed their attitude towards voluntary blood donation and explored their active involvement in donating blood through a validated questionnaire. Results: There were 89 female and 19 male participants in the study. Almost ev- ery student (96%) knew their blood group and most of them were correct about the health status of a blood donor. They had a lack of knowledge regarding the time required for blood donation and the amount of blood collected in each bag. Although most of the students were very favourable to donate blood, only 34% had previous experience of donating blood out of them; only 6% regularly donated voluntarily and on demand. Conclusion: From this finding, it can be recommended that measures for increasing knowledge regarding blood donation should be taken, and that would result in increased blood donation.

    Introduction: Unsafe blood products cause transfusion-transmissible infections among blood receivers. The knowledge and perception of blood donors is important as it is associated with their donation behaviour and hence the safety of blood products. There was no previous study that assessed the knowledge and perception on blood safety issues among blood donors to date. The objective of this study was to assess the knowledge and perception of blood
    donors on blood safety issues.
    Methods: This was a pilot study conducted to pilot test the self-developed questionnaire by the researchers. The questionnaire was available in the Malay language. One-hundred-thirty donors at the National Blood Centre were recruited to complete the self-administered questionnaire. Health sciences professionals, medical students and non-Malaysians were excluded in this study.
    Results: A total of 130 donors comprising of 70 males (53.8%) and 60 females (46.2%) responded. The mean age of the respondents is 32.48±8.86 years. Most of the respondents were Malay (55.4%), single (49.2%), working in private sector (46.9%) and regular donor (68.5%). More than half of the respondents did not know that dengue, Zika and mad-cow disease can be contracted through blood transfusion. Ten percent of the respondents answered that bisexual people are eligible to donate blood. 40.7% of the donors agreed to check their HIV status through blood donation. Majority of the donors (60.7%) agreed that the donors’ blood is safe if the screening test is negative. Whereas, 33.9% of the donors disagreed that they shall be responsible if their blood causes infection.
    Conclusion: Several knowledge gaps and inappropriate perception among the respondents were identified and these might affect the safety of the blood products. Targeted measures should be taken to rectify donors’ knowledge and perception in order to minimise inappropriate blood donor behaviours and reduce unsafe blood products.

    Introduction: It has been suggested that blood donation reduces risks of developing cardiovascular diseases such as heart failure, atherosclerosis, and stroke. Although there are known benefits of blood donation, the inclination of people of the Kurdistan Region of Iraq to donate blood is not known. Therefore, the aim of this study was to determine demograpic and blood biochemical profiles of regular and first-time blood donors in the Sulaimani province of North Iraq.

    Methods: A cross-sectional study was conducted at the Sulaimani Blood Bank, during the period of April 1, 2016 to March 28, 2017, on convenient samples of 100 regular and 100 first-time blood donors. Donor particulars were obtained from blood bank records. The cholesterol, triglyceride, low-density lipoprotein, ferritin, vitamin D3, and uric acid concentrations of blood samples were determined.

    Results: The main reason for blood donation by regular blood donors was headache (45%), while for the first-timers it was to help relatives (31%). The low-density lipoprotein and ferritin concentrations were significantly (p=0.001) lower in the blood of regular donors than first-timers.

    Conclusion: The study shows that regular blood donation is beneficial for the maintenance of health of donors.

    BACKGROUND: Low hemoglobin level is a common cause of donor deferral and results in a huge loss of the donor pool. This study aimed to evaluate the effectiveness of a mobile application as an educational tool to enhance donor return and improve hemoglobin levels after deferral.

    MATERIALS AND METHODS: This was an interventional study involving 382 blood donors who were deferred for low hemoglobin. The donors were divided equally into two groups: a control group and the intervention group. The control group received standard management for low hemoglobin deferral, which includes a short counseling session and a 1-month course of oral iron therapy. The intervention group used a mobile application in addition to standard management. The primary endpoint was the number of blood donors who returned during the 7 months of follow-up. The secondary endpoints were the hemoglobin increment at the first visit after the donors' deferral.

    RESULTS: The return rate was higher in the intervention group, with 81.2% of the donors returning in the 7 months of follow-up compared to 66% of the control group (p<0.001). Male and female donors had mean hemoglobin increments of 1.0 g/dL and 0.7 g/dL, respectively, in the intervention group, compared to decrements of 0.2 g/dL and 0.4 g/dL, respectively, in the control group (p<0.001). Multivariable analysis showed a significant association between intervention method, education level and donation status on donor return (p=0.015, p<0.001, and p<0.001, respectively).

    DISCUSSION: Higher return rate and greater hemoglobin increase in the interventional group could be attributed to features in the mobile application. Repeat donors had the highest odds of returning to donate, followed by those with a tertiary level of education, and those given the mobile application. This study showed that a mobile application was effective in enhancing donor return and increasing hemoglobin level among deferred blood donors on their first return.

    The aim of this study was to screen and identify the types of thalassemia among blood donors at the Hospital Universiti Sains Malaysia (HUSM). Thalassemia screening was performed by hemoglobin electrophoresis. A total number of 80 blood samples were obtained from donors at the Transfusion Medicine Unit, HUSM. The ethnic origins of the donors were Malays (n=73, 91.3%) and non-Malays (n=7, 8.75%). Males comprised 88.1% of the donors. Thalassemia was detected in 16.25% (n=13) of the blood donors. Of those with thalassemia, 46.2% (6/13) were anemic. Microcytosis and hypochromia were detected in 84.6% (n=l1) and 84.6% (n=l1) of these donors, respectively. The types of thalassemias detected were Hb E, 11.25% (n=9/80) and beta thalassemia trait, 5% (n=4/80). Among the thalassemias detected, the Hb E hemoglobinopathy was comprised of Hb E/ alpha-thalassemia (38.5%: n=5), Hb E /beta-thalassemia (23.1%: n=3), Hb E trait (7.6%: n=1) and beta-thalassemia (30.8%: n=4). In conclusion, screening for thalassemia trait should be included as part of a standard blood testing before blood donation. Further studies are required to look at the effects of donated thalassemic blood.

    Introduction: Glucose-6-phosphate dehydrogenase (G6PD) deficiency causes red blood cell destruction due to oxi- dative stress. G6PD is essential for NADPH conversion; which is critical for glutathione reductase to prevent damage to cellular structures. In Malaysia, blood donors are not routinely screened for G6PD deficiency. We hypothesise that G6PD-deficient red blood cells are more likely to haemolyse during storage due to increased oxidative molecules. The objectives of this study were to determine the prevalence of G6PD deficiency among blood donors, describe their characteristics and to evaluate the effects of storage on G6PD-deficient donated blood. Methods: This study was conducted at selected mobile donation centres in Terengganu. Consented blood donors were screened for G6PD sta- tus using fluorescent spot tests (FST). G6PD enzyme activities were measured for donors who were G6PD deficient. Effects of storage on haemolysis from G6PD-deficient donors were compared with non G6PD-deficient group. Sixty ml of blood was collected from blood unit to transfer pouch for estimation of haemoglobin (Hb), plasma Hb, per- centage of haemolysis and plasma potassium. Serial sampling with a 7-day interval was done from Day 1 to Day 35. Statistical analysis was considered significant if p 0.05. Results: A total of 440 blood donors were screened and 12 male donors were found to be G6PD deficient by FST. Enzymatic activities were measured in 11 donors as one donor sample failed to be sent to the centre due to logistic problem. Their enzymatic activities ranged from 1.66-2.93 U/g Hb whereby 6 have severe deficiency and the other 5 were categorised as partial deficiency. Donors were asymp- tomatic for haemolytic episode. Serial sampling showed there was no significant difference of haemolytic parameters in blood units of G6PD-deficient donors as compared to control (p>0.05). Conclusion: Prevalence of G6PD blood donors in Terengganu mobile centres was 2.7%. G6PD enzyme activities did not correlate with clinical symptoms. Haemolytic parameters were not affected in blood units which were G6PD-deficient.

    Malaysia is a medium endemic country for hepatitis B virus (HBV) infection but little is known about HBV strains circulating in Malaysian blood donors. Viral load, HBsAg concentrations and nested PCR products from 84 HBV surface antigen (HBsAg) positive samples were analysed in detail. Median viral load was 3050 IU/mL and median HBsAg 1150 IU/mL. Fifty-six full genome, 20 pre-S/S, 1 S gene and six basic core promoter/precore-only sequences were obtained. Genotypes B and C were present at a ratio of 2:1, and two genotype D samples were obtained, both from donors of Indian background. Phylogenetically, genotype B was more diverse with subgenotypes B2-5, B7 and B8 present, while most genotype C strains were from subgenotype C1. Genotypes B and C were equally frequent in ethnic Malays, but 80% of strains from Chinese were genotype B. HBsAg concentrations were higher in genotype C than in genotype B, in Chinese than Malays and in donors under the age of 30. HBV vaccine escape substitutions (P120S/T, I126N and G145G) were present in six strains. In the large surface protein, immuno-inactive regions were more mutated than CD8 epitopes and the major hydrophilic region. Strains of genotype B or from ethnic Malays had higher genetic diversity than strains of genotype C or from Chinese donors. Hence HBV strains circulating in Malaysia are phylogenetically diverse reflecting the ethnic mix of its population. Ethnic Malays carry lower HBsAg levels and higher genetic diversity of the surface antigen, possibly resulting in more effective immune control of the infection.

    The prevalence of antibodies to hepatitis E virus (HEV) has been examined in many countries, but such studies have generally been limited to majority populations such as those represented in healthy blood donors or cross sections of urban populations. Due to its major route of enteric transmission, large differences in HEV prevalence might be expected between populations in the same country but with different living conditions. Using an ELISA based on GST-ORF2.1 antigen, the prevalence of IgG-class antibodies to HEV was examined in three distinct populations in Malaysia: the normal (urban) blood donor population and two aboriginal communities located at Betau, Pahang and Parit Tanjung, Perak. IgG anti-HEV was detected in 45 (44%) of 102 samples from Betau and 15 (50%) of 30 samples from Parit Tanjung, compared to only 2 (2%) of 100 normal blood donors. The distribution of sample ELISA reactivities was also consistent with ongoing sporadic infection in the aboriginal communities, while there was no significant relationship between HEV exposure and age, sex, or malaria infection. The high prevalence of antibodies to HEV in the two aboriginal communities indicates that this group of people are at high risk of exposure to HEV compared to the general blood donors, and the results suggest that studies of HEV seroprevalence within countries must take into account the possibility of widely varying infection rates between populations with marked differences in living conditions.

    Hepatitis C virus (HCV) is the chief aetiologic agent for the parenterally transmitted Non-A, Non-B (NANB) hepatitis. This preliminary study was done to determine the prevalence of anti-HCV in the blood donor population. Blood from 3,540 donors who donated blood to the Blood Services Centre, Hospital, Kuala Lumpur, from 25th August 1991 to 13th January 1992, was tested for anti-HCV using both the Ortho and Abbott 2nd Generation ELISA test kits. ELISA positive specimens were repeated twice but no confirmatory test was done. There were 53 out of 3,540 (1.49%) blood donors who were repeatedly reactive to anti-HCV by ELISA. We plan to do further tests to confirm the results, using RIBA-2 or Abbott Neutralising test. Twenty eight out of 1,713 (1.63%) Malays, 22 out of 1,373 (1.60%) Chinese and 2 out of 393 (0.50%) Indians had antibodies to HCV. There was no significant difference in prevalence in the different age groups. The majority of donors tested were males (3,511 out of 3,540) of which 53 (1.50%) were anti-HCV positive. Only 29 females were tested and all were negative. To determine infectivity of the anti-HCV positive cases we would like to introduce testing for RNA by polymerate chain reaction (PCR). Screening all donated blood for anti-HCV will decrease, but not totally eliminate, post-transfusion hepatitis.

    Hemovigilance like quality systems and audits has become an integral part of the Blood Transfusion Service (BTS) in the developed world and has contributed greatly to the development of the blood service. However developing countries are still grappling with donor recruitment and efforts towards sufficiency and safety of the blood supply. In these countries the BTS is generally fragmented and a national hemovigilance program would be difficult to implement. However a few developing countries have an effective and sustainable blood program that can deliver equitable, safe and sufficient blood supply to the nation. Different models of hemovigilance program have been introduced with variable success. There are deficiencies but the data collected provided important information that can be presented to the health authorities for effective interventions. Hemovigilance program modeled from developed countries require expertise and resources that are not available in many developing countries. Whatever resources that are available should be utilized to correct deficiencies that are already apparent and obvious. Besides there are other tools that can be used to monitor the blood program in the developing countries depending on the need and the resources available. More importantly the data collected should be accurate and are used and taken into consideration in formulating guidelines, standards and policies and to affect appropriate interventions. Any surveillance program should be introduced in a stepwise manner as the blood transfusion service develops.

    A review of 352 patients with primary liver cell carcinoma treated by the author is presented. The poor rate of resectability (7 per cent) has necessitated various forms of treatment over the years. These are described in detail. Based on this experience, the current form of treatment for nonresectable carcinoma is summarized. Although it is too early to assess this form of treatment, initial results appear to be promising. A second report in the near future is planned.

    T. gondii is a life-threatening infection in immunocompromised patients which may be transmitted through blood transfusion. The present study aimed to evaluate the seroprevalence and molecular detection of T. gondii infection and the associated risk factors among young healthy blood donors in the central part of Mazandaran province, northern Iran. Blood samples were taken from 500 participants and the serum was separated. All serum samples were tested for the presence of anti-T. gondii antibodies (IgG) and then all positive samples were evaluated for IgM antibodies using commercial ELISA kits. All IgM positive samples and 66 randomly selected IgG positive samples were further tested by PCR of the REP-529 gene. Anti-Toxoplasma antibodies (IgG) avidity test was performed for 142 IgG positive samples which were randomly selected. In the current study, anti-T. gondii antibodies (IgG) and (IgM) were found in 316 (63.2%) and 3 (0.95 %) participants, respectively. Seropositivity rate of Toxoplasma was higher among blood donors living in rural areas (P=0.000) and those with a history of soil and animal contact (P<0.05). PCR of the REP-529 gene showed T. gondii DNA in 21 out of 66 samples. The REP-529 gene was not detected in IgM positive samples. Low avidity antibodies (IgG) was found in 23.2% of the IgG positive samples. In conclusions, this study found that the prevalence of toxoplasmosis among young healthy blood donors in north of Iran was high. To reduce the risk of parasite transmission, leukofilteration method are recommended for donated blood used for immunosuppressed patients.

    Paroxysmal nocturnal haemoglobinuria (PNH) is an acquired haemopoietic stem cell disorder arising from somatic mutation of the X-linked PIG-A gene which leads to deficiency of the glycosylphosphatidylinositol (GP1) membrane anchor proteins such as CD 59 (MIRL: membrane inhibitor of reactive lysis) and CD 55 (DAF: decay accelerating factor). Allogeneic peripheral blood stem cell transplant (PBSCT) is a curative mode of treatment in symptomatic PNH patients. Assessment of donor chimerism for PBSCT can be performed by various methods including short tandem repeat loci (STR) and variable number of tandem repeats (VNTR). Flow cytometry, which is much cheaper and faster, also can be used to assess engraftment in patients with PNH. Engrafted patients will show the presence of CD 55 and CD 59 on their red cells and white cells. We describe here the usefulness of flow cytometry in the assessment of donor chimerism following allogeneic PBSCT, in a case of PNH.

    Objective: This study was done to identify blood donors with thalassaemia and iron deficiency. A cross sectional study was carried out at Pusat Darah Negara (PDN), Kuala Lumpur in November 2003.
    Methods: Full blood counts were done on 242 blood donors (166 males and 76 females) Hb analysis and serum ferritin assay were done for all the samples. The first time donors were used as controls.
    Results: Only 20 (8.3%) donors had MCV <80 fL and MCH <26pg. Six of the 25 donors with iron deficiency had a low MCV <80 fL) and low MCH <26 pg) but all the 8 (40%) donors with thalassaemia or HbE had a low MCV and MCH! The mean ferritin levels were found to be lower among regular blood donors (95.3 ug/L) compared to first time blood donors (116.6 ug/L) but this was not statistically significant. There were 25 donors who were iron deficient: one was a first time donor and 24 were regular donors - 12 (50%) had donated 3 times a year in the last two years. Iron deficiency was seen in 12 Malays, and 9 Chinese, and 4 Indians. 13.3% of the males (22 out of 166 donors) and 4% (3 of 76) of female donors were iron deficient. Thalassaemia and HbE were found in 8 donors. HbE trait was identified in 5 Malay donors. One Malay and 1 Chinese donor had beta-thalassaemia trait. Another Chinese had alpha (a^o) thalassaemia trait. Neither HbE nor thalassaemia were seen in the Indian donors.
    Conclusion: In this study thalassaemia and RbE were seen in 3.3% and iron deficiency in 10.3% of the 242 blood donors at PDN. Iron deficiency was present in 3.2% of the first time donors and 12.8% of the regular donors. Regular donors should have the serum ferritin done for their iron status and if their MCV and MCH are low, Hb analysis for thalassaemia or haemoglobinopathy.
