The Sn(IV) atom in the title diorganotin compound, [Sn(C7H6F)2Cl2(C2H6OS)2], is located on a centre of inversion, resulting in the C2Cl2O2 donor set having an all-trans disposition of like atoms. The coordination geometry approximates an octa-hedron. The crystal features C-H⋯F, C-H⋯Cl and C-H⋯π inter-actions, giving rise to a three-dimensional network. The respective influences of the Cl⋯H/H⋯Cl and F⋯H/H⋯F contacts to the mol-ecular packing are clearly evident from the analysis of the Hirshfeld surface.

Fulltext Willingness and Perceived Barriers towards Organ Donation among Student Nurses in Universiti Malaysia Sabah

R. Segaran, Mohd Amsyar Bacho, Asrani Yaco

Borneo Journal of Medical Sciences, 2018;12(101):67-68.

MyJurnal

Organ transplant has become a main stream important medical procedure commonly used in hospitals. However, for organ transplant programme to be successful, it heavily relies on the public to voluntarily register for organ procurement. Effort to promote awareness and register public as organ donors has been ongoing, but public response to commit and register as donors has been lukewarm. Arguably, healthcare personnel and nurses are in a key position to educate and advocate for organ donation but often, ironically healthcare personal themselves are reluctant or unwilling to commit as organ donors. Thus, in the context of student nurses in Universiti Malaysia Sabah (UMS), the question arises, what is their stance and views regarding organ donation.

Fulltext The influence of socioeconomic and demographic variables on willingness to donate cadaveric human organs in Malaysia

Rasiah R, Manikam R, Chandarsekaran SK, Thangiah G, Puspharajan S, Swaminathan D

Medicine (Baltimore), 2014 Nov;93(23):e126.

The growing shortage in human organs has raised serious concerns. To address this problem, we examine in this article the association between demographic and socioeconomic factors, and respondents' willingness to donate cadaveric organs using a large survey of Malaysian adults aged 18 years and above.A convenience sampling method was used to extract information from a total of 10,350 participants from Metropolitan Kuala Lumpur over the period of April 2, 2013 to February 29, 2014. In addition to analyzing the data using incidence of willingness to donate by demographic and socioeconomic factors, we carried out logistic regression analysis to estimate the odds ratio of respondents' willingness to become cadaveric organ donors controlling for age.About less than a third of the participants pledged to donate their organs upon death with women (35.6%) showing a higher incidence compared with men (33.2%). The Chinese (35.7%) and Malays (35.0%) pledged to contribute more than the Indians (31.6%) and the logistic regressions show that Malays (adjusted odds ration [OR] = 1.18) and Chinese (adjusted OR = 1.21) are more likely to donate than Indians (reference group). The results by religion were significant among Muslims and Hindus but not Buddhists. The likelihood of Muslims donating was the lowest (adjusted OR = 0.26). Income was also highly significant but the relationship with willingness to donate was negative. Against tertiary education, all other occupations were significant. However, the respondents with primary education enjoyed the highest adjusted OR (5.46) whereas that of secondary (0.48) and higher secondary (0.83) education was low. Among occupations (against supervisory, clerical, and direct workers), it was significant only among the unemployed and managers with adjusted OR of 1.50 and 1.58, respectively.Sex, education, ethnicity, religion, and income are important demographic and socioeconomic influences on the likelihood of Malaysians willing to become cadaveric organ donors. The Malaysian evidence suggests that awareness programs should be targeted at men, Muslims, Hindus, Malays, and the rich more than the others.

PMID: 10968039

This is the first report in South East Asia of a singleton frozen embryo donation pregnancy for hypergonadotrophic hypogonadism. The hormonal profile was compared with that of a control group of normal uncomplicated singleton pregnancies in Singapore. The plasma beta hCG levels were lower compared to those of our normal uncomplicated singleton pregnancies at 2 to 3 weeks after the embryo transfer but became comparable at 4 to 5 weeks after embryo transfer. The successful vaginal delivery and the obstetric complications developed in this case are discussed.

The Tzu Chi Silent Mentor Program: Application of Buddhist Ethics to Teach Student Physicians Empathy, Compassion, and Self-Sacrifice

Santibañez S, Boudreaux D, Tseng GF, Konkel K

J Relig Health, 2016 Oct;55(5):1483-94.

PMID: 26311054 DOI: 10.1007/s10943-015-0110-x

The Buddhist Tzu Chi Silent Mentor Program promotes the donation of one's body to science as a selfless act by appealing to the Buddhist ethics of compassion and self-sacrifice. Together, faculty, families, and donors help medical students to learn the technical, spiritual, emotional, and psychological aspects of medicine. Students assigned to each "Silent Mentor" visit the family to learn about the donor's life. They see photos and hear family members' stories. Afterwards, students write a brief biography of the donor which is posted on the program website, in the medical school, and on the dissection table. In this paper, we: (1) summarize the Silent Mentor Program; (2) describe findings from an assessment of medical students who recently completed a new version of the program in Malaysia; and (3) explore how healthcare settings could benefit from this innovative program.

Social and cultural aspects of organ donation in Asia

Woo KT

Ann Acad Med Singap, 1992 May;21(3):421-7.

PMID: 1416796

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.

Requirements for the development of a hand transplantation program

Gordon CR, Siemionow M

Ann Plast Surg, 2009 Sep;63(3):262-73.

PMID: 19692900 DOI: 10.1097/SAP.0b013e31818d45e9

Since 1998, 42 hand transplants in 30 patients have been performed in countries such as France, United States, China, Austria, Malaysia, Italy, Belgium, Poland, Spain, and Germany. Now, with recent improvements in immunosuppression, the clinical applicability may expand and the ethical obstacles may soon be overcome, allowing multiple US institutions to perform hand allotransplantation. The main purpose of this article is to facilitate access to pertinent details in regards to hand transplantation, such as donor/recipient selection criteria, immunosuppressive therapies, and associated complications. It is a comprehensive literature review compiled from published reports from multiple hand transplant programs throughout the world. Due to its inherent complexity, hand transplantation should only be attempted at institutions within the US capable of orchestrating a specialized multidisciplinary team, and each institution's protocol should be extremely detailed and individualized.

Ann. Transplant., 2015;20:424-9.

PMID: 26218888 DOI: 10.12659/AOT.894003

Transplantation and transfusion are related and clinically important areas of multidisciplinary expertise, including pre-operative treatment, donor recruitment, tissue matching, and post-operative care. We have seen significant developments in these areas, especially in the late 20th and early 21st century. This paper reviews the latest advances in modern transplantation and transfusion medicine, including several new genetic markers (e.g., major histocompatibility complex class I chain-related gene A, killer cell immunoglobulin-like receptor, and human platelet antigens) for donor and recipient matching, genotyping platforms (e.g., next-generation sequencer and Luminex technology), donor recruitment strategies, and several clinical applications in which genotyping has advantages over agglutination tests (e.g., genotyping of weakly expressed antigens and determination of blood groups and human leukocyte antigen types in multi-transfused patients). We also highlight the roles of population studies and international collaborations in moving towards more efficient donor recruitment strategies.

Fulltext Quantitative evaluation of chimerism status following haematopoeitic stem cell transplantation using a microchip electrophoresis system

Daud, S.S., Ibrahim, K., Ariffin, H.

JUMMEC, 2007;10(1):11-16.

MyJurnal

We aimed to establish a method for quantitative analysis of mixed haematopoietic chimerism based on microchip electrophoresis of selected molecular markers following PCR amplification for accurate monitoring of graft status post-transplantation. A 12-year-old girl with relapsed acute lymphoblastic leukaemia who underwent allogeneic bone marrow transplantation had qualitative chimerism analysis using short tandem repeat markers at three time points following the procedure. Her archived DNA samples were then used to test the ability to correlate her clinical course with changes in the quantity of donor chimerism at the different time points. Quantitative chimerism analysis was performed on the Agilent 2100 bioanalyser and donor-recipient ratios were calculated from generated electropherograms. Complete donor chimerism (98%) was demonstrated three weeks post- transplantation. Decreasing amount of donor chimerism to 24% was shown after three months and this concurred with clinical relapse. Following a second transplant, full donor chimerism was reestablished where donor chimerism rose to 100%. High resolution microchip electrophoresis could be useful in predicting the occurrence of increasing recipient chimerism which may herald impending relapse in patients while the disease burden is still low. This investigational approach may provide useful information for clinicians to select appropriate intervention strategies to ensure successful transplantation.

Fulltext Quantitative and qualitative evaluation of sural nerve graft donor site

Ng SS, Kwan MK, Ahmad TS

Med J Malaysia, 2006 Dec;61 Suppl B:13-7.

PMID: 17600987

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.

Fulltext Prioritizing Factors Affecting Deceased Organ Donation in Malaysia: Is a New Organ Donation System Required?

Naghavi N, Mubarik MS, Rasiah R, Sharif Nia H

Int J Gen Med, 2020;13:641-651.

PMID: 32982381 DOI: 10.2147/IJGM.S253372

Purpose: The gap between the demand and the supply of human organs for transplantation is on the rise in Malaysia, despite the efforts of governments to promote donor registration. Factors affecting willingness to donate are contextual and vary from country to country. This research mainly focuses on the selection of most suitable organ donation system through factors affecting willingness to donate in Malaysia. The objectives of this study are to prioritize those factors acting as the pillars of the organ donation system and further to select the most suitable organ donation system for Malaysia.

Patients and Methods: The data were collected from 35 experts by using a bipolar questionnaire. The study applied an analytical hierarchal process (AHP) for prioritization factors contributing to willingness to donate and then selection of a suitable organ donation system based on prioritized factors.

Results: Based on the AHP results, it is evident that donation perception (0.36) has the highest priority in influencing organ donation rates, followed by socioeconomic status (0.32), demographic factors (0.23), and financial incentives (0.09). Further, our results challenge the existing opt-in donation system in Malaysia and present a presumptive approach as a suitable system for increasing deceased donation rate in Malaysia. Presumptive approach promotes the role of health-care professionals in securing the family consent.

Conclusion: This approach is a person-oriented rather than process-oriented strategy and it relies on designated requesters' skills to evoke altruism among bereaved families. Based on results, the authors recommended that relevant government agencies focus on training nurses to discuss donation with bereaved families and raising public awareness.

Predictors of the yield of mobilized peripheral blood CD34+ cells in HLA-matched sibling donor

Fadilah SA, Mohd-Razif MI, Seery ZA, Nor-Rafeah T, Wan-Fariza WJ, Habsah A, et al.

Transfus Apher Sci, 2013 Dec;49(3):583-9.

PMID: 24012241 DOI: 10.1016/j.transci.2013.07.032

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.
