    INTRODUCTION: Healthcare professionals (HCPs) working in critical care areas play an important role in the organ donation (OD) process. We studied HCPs' own willingness to be organ donors and its association with sociodemographic factors as well as their knowledge and attitudes about OD and transplantation.

    METHODS: A cross-sectional survey of HCPs working in four critical care units in a major transplant centre in Malaysia was undertaken using a validated structured questionnaire. Responses were analysed using multivariable analysis with willingness to donate as the dependent variable.

    RESULTS: Of the 412 respondents (response rate 98.1%), the majority were nurses (60.4%), Malay (71.1%) and female (77.2%). Overall, 68.0% were willing to donate. The independent predictors of willingness to donate were profession (p < 0.001) and the Hindu religion (p = 0.001). Ethnicity (p = 0.003), religious belief (p < 0.001), knowledge (p = 0.016), belief in brain death (p = 0.018) and confidence in transplantation (p < 0.001) also independently correlated with willingness to donate, while attitudes to OD did not. Of those willing to donate, only 37.3% were carrying a donor card and only 63.1% had informed their family of their intention to donate.

    CONCLUSION: Although willingness to donate was higher in critical care HCPs than HCPs in general, significant knowledge gaps as well as certain beliefs and perceptions that could pose a barrier to OD were identified in this group. Measures to improve OD rates in Malaysia should include targeted educational programmes for HCPs working in critical care areas.

    In Asian countries, it is more difficult to obtain cadaver kidneys for renal transplantation because of certain socio-cultural beliefs and customs. The issues affecting living related kidney donation are more social than cultural. This is due to the web of family pressures and personal conflicts for both donor and recipient surrounding the donation. Important misconceptions and fears are: fear of death, the belief that removal of organ violates sanctity of decreased, concern about being cut up after death, desire to be buried whole, dislike of idea of kidneys inside another person, wrong concept of brain death, and the idea of donation being against religious conviction. In Singapore, with the introduction of the Human Organ Transplant Act (HOTA) in 1988, the number of cadaveric transplants have increased, including those from the Medical Therapy Act (MTA). HOTA and education have played pivotal roles in bringing about an increased yield of cadaveric kidneys. With the availability of living unrelated donor (LUD) transplants in India, our living related donor (LRD) transplant programme has suffered, because patients would rather buy a kidney from overseas than get a relative to donate one. Patients are also going to China for overseas cadaveric transplants where the kidneys come from executed convicts. People in countries like Hong Kong, Japan and the Philippines share the same Asian tradition of not parting with their organs after death. Muslim countries like Malaysia require the deceased to have earlier pledged his kidneys for donation prior to death before they can be harvested for transplantation at death.

    INTRODUCTION: Worldwide, the gap between organ supply and demand has widened over the years. Malaysia has one of the lowest deceased organ donation rates. Success rate of organ or tissue procurement depends on not only the approach rate by health care providers but also the awareness among the public, whereby it can be a platform for family initiation of organ donation. The purpose of this study is to assess the knowledge of and determine the factors influencing attitude toward organ and tissue donation among patients in a primary clinic.

    METHODS: A cross-sectional analytical study was carried out. Self-administered questionnaires were given to 400 patients who registered at an outpatient clinic in April 2018. Convenience sampling was applied.

    RESULTS: Monthly income, education level, occupation, and knowledge level are significantly associated with attitude of the respondents toward organ and tissue donation. Occupation influenced attitude toward organ donation. Knowledge of organ donation and brain death both significantly affected attitude toward organ donation.

    CONCLUSION: The greater the knowledge of organ donation and brain death, the more positive impression or attitude toward organ donation. Education level and income are the main predictors that influence attitude toward organ donation. Hence, it is important for public health units to promote and deliver public education on organ donation, change public misconceptions, and work parallel with hospitals to increase organ donation rates in Sabah.

    BACKGROUND: Malaysia, which currently uses the informed consent system (ICS), is suffering from a severe shortage of organs for transplantation. Family members of dialysis patients (FMDPs) are expected to have a positive attitude toward deceased organ donation (DOD) because they have a close relative in need of a kidney donation. This study explores FMDPs' attitude toward DOD under the ICS and the presumed consent system (PCS).

    MATERIAL/METHODS: The attitude of 350 FMDPs toward DOD under the ICS and PCS were sought between June and October 2013 in 3 dialysis institutions in Kuala Lumpur, Malaysia.

    RESULTS: Under the ICS, 6.6% of respondents were registered donors, 6.6% were ready to register at the time of the survey, 38.6% were willing to donate but not ready to register at the time of the survey, and 48.2% were unwilling to donate organs upon death. If the PCS were implemented, 57.7% of respondents (28.7% of the willing donors and 88.7% of the unwilling respondents) stated that they would officially object to organ donation.

    CONCLUSIONS: FMDPs' attitude toward DOD is not more positive or significantly better than that of the general public (based on earlier studies). The PCS may increase the number of donors, but it may also worsen the attitude of FMDPs toward DOD. Strategies aiming to promote DOD in Malaysia should be revised, and should perhaps be focused on enhancing trust of the medical system.

    This study is designed to evaluate twenty patients after sural nerve harvest using the single longitudinal incision method. The area of sensory loss to pin prick was assessed by the authors at different intervals. Donor site factors, scar cosmesis, functional status and complications were assessed using a questionnaire. The mean area of anaesthesia at one month was 65 cm2 and it had reduced by 77% to 15 cm2 at one and a half years. The mean area of reduced sensation was 49 cm2 at one month and it increased by 18% to 58 cm2 over the same period. Therefore, the total area of sensory deficit was reduced by 36% from 114 cm2 at one month to 73 cm2 at one and a half years. Subjective patient evaluation indicated moderate level of pain during immediate post surgical period, which reduced significantly at one month. A low level of neuroma symptoms was recorded throughout the study period. At a mean follow-up period of two years, there was no area of anaesthesia in 50% of the patients. Mean area of anaesthesia for all patients was 12 cm2 and mean area of reduced sensation was 55 cm2. Subjective patient evaluation indicated a low level of pain, neuroma symptoms and numbness over the sural nerve sensory distribution. Twenty five percent of the patients were not satisfied with the scar appearance. Function and daily activities were not affected significantly. No surgical complications were observed.

    BACKGROUND: Blood transfusion during the post-operative period of kidney transplantation is common as part of a life-saving procedure, especially in the event of acute blood loss. However, there have been conflicting opinions since the pre-cyclosporine era. The risk of sensitization post-transfusion remains the main limiting factor following transfusion in kidney transplant recipients. Thus, the objective of this study is to assess the development of de novo HLA-DSA, HLA-Ab and allograft rejection post blood transfusion.

    METHODOLOGY: This is a retrospective cohort study recruiting all kidney transplant recipients in South Australia from January 2010 till December 2018. Following that, the incidence of blood transfusion within one week post-operatively were traced (transfusion group). The outcomes were compared with all other transplant recipients (non-transfusion group). Recipient's demographic, donor characteristics and immunological risk profiles were obtained from the transplant unit database, while the biopsy report, history of blood transfusion, latest serum creatinine and follow-up status was gathered from the electronic medical system (OASIS). The HLA-DSA and HLA-Ab results were collected from the NOMS database. Finally, the survival data were merged with the Australia and New Zealand Dialysis and Transplant (ANZDATA) Registry for South Australia recipients graft survival.

    RESULTS: A total of 699 patients were eligible for analysis. The mean age was 50.64 ± 13.23 years old. There were more elderly (>65 years old) and females who needed transfusion. The majority had glomerulonephritis as the primary disease. There was no statistical difference in donor characteristics, cold ischemic time and immunological risk between the transfusion and non-transfusion group. There was no difference in the development of de novo HLA-DSA, HLA-Ab and rejection episodes between the group and the results were consistent in a model adjusted for all potential confounders. Median graft survival in days between the transfusion vs non-transfusion group was 1845 IQR (961,2430) and 1250 IQR (672,2013).

    CONCLUSION: Blood transfusion under strong immunosuppressive cover within a one-week post-operative period is safe with no significant association with the development of de novo HLA-DSA, HLA-Ab or clinical rejection.

    A 25-month-old boy with beta-thalassaemia major was presented with an opportunity for umbilical cord blood transplantation when his unborn sibling was diagnosed in utero to be a beta-thalassaemia carrier and also human leucocyte antigen compatible. A barely adequate amount of cord blood was collected at the birth of his sibling and infused into the patient after appropriate chemo-conditioning. Engraftment occurred without major complications. The subject is now alive and well 9 months post-transplant, thus marking our first success in umbilical cord blood transplantation.

    Currently, there are no harmonized guidelines which govern skin banking in the Asia Pacific region. Therefore, skin banks are either unregulated or rely on their nation's legislation or international accreditation to uphold their quality standards. A new set of skin banking guidelines was developed through a comprehensive review and collation of best international practices for the Asia Pacific Burn Association (APBA) members, from donor screening and testing, to skin recovery, processing, storage and distribution, and quality assurance. National regulatory requirements reviewed include the European directives, Australia's Therapeutic Goods Administration and Singapore's tissue banking standards. Further technical and quality management recommendations are referenced from the American Association of Tissue Banks (AATB), the United States Food and Drug Administration standards and guidance documents, various relevant European guides, Japanese Society of Tissue Transplantation guidelines and the Asia Pacific Association of Surgical Tissue Banking. Adapted mainly from the AATB standards, the new Asia Pacific Burn Association Guidelines for Skin Banking in Therapeutic Applications offer a comprehensive manual, addressing: governance and contracts; staff responsibilities; quality management; facilities, equipment and supplies management; donor consent and testing; and recommendations of good practices pertaining to skin recovery, processing, storage and distribution. Besides complementing current generic regulations, they provide technical specifications of major aspects unaddressed in most legislations. This inaugural set of new regional skin banking guidelines would be a start for regional members of the APBA to adopt, and will hopefully culminate in a set of standards so that, in the long run, skin allografts from this region can be of similar quality, which can simplify import process and facilitate the exchange of allografts between members.

    The follow-up of chimerism status after allogeneic haematopoietic stem cell transplantation (HSCT) is essential to predict successful engraftment to assess the development of graft-versus-host disease, graft rejection and disease relapse. Analysis of short tandem repeats (STR) via polymerase chain reaction is frequently used for chimerism determination. However, most commercially-available kits have been designed for forensic purposes and may not be optimal for chimerism analysis. The present study aims to identify suitable STR markers for patient-donor pairs of predominantly Malay and Chinese ethnicity using two commercially-available forensic kits.

    We examined the donor factors that may affect the yield of peripheral blood stem cell (PBSC) mobilized from healthy donors. Pre-apheresis PB-CD34(+) cell count was the only factor that correlated with PBSC yield. Leukocyte count (LC) and monocyte count (MC) correlated with PB-CD34(+) cell. Male gender and PB-CD34(+) cell count of at least 87.1/μL and 69.8/μL on day-4 and -5 of G-CSF were associated with the ability to harvest at least 5×10(6)/kg CD34(+) cells after one apheresis. We concluded that gender and PB-CD34(+) cell count are important predictors of PBSC yield. LC and MC may serve as surrogate markers for estimating the PB-CD34(+) cell count.

    Functional renal reserve is a measure of the capacity of the kidney to increase the glomerular filtration in response to the stimulus of a protein meal or amino acid infusion. The aim of this study was to evaluate the usefulness of protein meal test to measure functional renal reserve in normal subjects and various groups of renal patients. One hundred and twenty five subjects from the Nephrology Clinic, Kuala Lumpur General Hospital were subjected to a protein loading test to measure their renal reserve. Each subject had to eat a 100 gram cooked chicken meat and timed 2 hours urine collections before and after the test meal were done to measure the creatinine clearances. The 62 healthy subjects showed a mean renal reserve (creatinine clearance after protein loading-baseline creatinine clearance) of 31.0 ml/min. The 31 subjects with various kidney diseases showed a mean renal reserve of 13.5 ml/min. The 19 renal transplant recipients showed renal reserve of 13.2 ml/min. The 12 nephrectomised donors showed renal reserve of 5.4ml/min. Renal reserve may be used to assess suitability of living related transplant donor for nephrectomy.
