Introduction: Unsafe blood products cause transfusion-transmissible infections. A good knowledge and perception about blood safety issues is crucial to ensure safe blood supply. The objective is to develop and validate a question- naire about the knowledge and perception among blood donors on blood safety issues. Method: A cross-sectional study was conducted among 130 blood donors who attended the National Blood Centre, Kuala Lumpur in April and May 2018. The questionnaire was developed in the Malay language after extensive literature search. The self-admin- istrated questionnaire consisted 39 items which required around 20 minutes to complete. The validation involved content validity, construct validity using exploratory factor analysis and reliability using test-retest analysis in IBM SPSS statistics. The same group of respondents was retested after two weeks using the same questionnaire. Results: Content validity was established through multidisciplinary expert meeting and two content reviewers. The factors loadings of all questionnaires were more than 0.40. Knowledge questions were divided into three domains; percep- tion questions were divided into four domains. The intraclass correlation (ICC) values of the test-retest were more than 0.80 for the three knowledge domains and more than 0.60 for the four perception domains. The third domain of the perception section which consisted two questions had the lowest ICC value of 0.686 (95% CI 0.583-0.767). One of the questions was restructured to improve clarity. Conclusions: The questionnaire on knowledge and perception on blood safety issues has good validity and reliability, with appropriate items which warranted its utilization among blood donors.
Introduction: Nurses are generally trained on the procedures of blood transfusion during their years of service. However, the level of knowledge varies among individuals and healthcare centres. Thus, this study addresses a knowledge gap regarding nurses’ knowledge and transfusion safety in the local clinical setting. Objectives: This study aimed to determine nurses’ level of knowledge of various phases of blood transfusion and associate this knowledge with their socio-professional details. Methods: This was a cross-sectional, quantitative study. The target population was in-patient ward nurses at Hospital Pulau Pinang. The systematic random sampling method was used to select 185 nurses to participate in this study. Data were collected using a validated research questionnaire that consisted of 31 items (9 items related to socio-professional factors and 22 knowledge items). Data were analysed using descriptive and inferential analyses. Results: The overall knowledge score was moderate (mean = 70.44%, SD = 11.35). None of the nurses was able to answer all of the knowledge questions correctly. Of the participants, 72.29%, 71.75%, and 67.14% exhibited knowledge of blood bag collection and patient preparation; pre-transfusion nursing activities; and during and post-transfusion nursing responsibilities and management of transfusion reactions, respectively. Factors such as age, years of service, department, and availability of the transfusion policy in the ward significantly affected the mean knowledge scores. Conclusion: Nurses’ knowledge of blood transfusion at Hospital Pulau Pinang was moderate. More training and courses should be provided to improve their knowledge.
Introduction: Rac1 and STIM1 genes are emerging therapeutic targets for cancers. However, their roles in acute my- eloid leukaemia (AML) are not well understood. The goal of this study was to evaluate the effects of dose and time on Rac1 and STIM1 knockdown in the AML cell line model (THP-1 cells). Methods: THP-1 cells were transfected with siRac1 at doses of 50, 100, and 200 nM or dsiSTIM1 at doses of 2, 5, and 10 nM. Expression level of Rac1 and STIM1 then were assessed at time points between 12 and 72 h post-transfection using real-time reverse transcription poly- merase chain reaction. Results: Compared to the control, 87% Rac1 knockdown was attained with 50 nM siRac1 at 24 h post-transfection, and 70% STIM1 knockdown was achieved with 10 nM dsiSTIM1 at 48 h post-transfection. Conclusion: These results show that effective knockdown of Rac1 and STIM1 is possible, and therapy that includes Rac1 and STIM1 inhibitors eventually could provide a new and highly effective strategy for AML treatment.
Introduction: Transfusion Medicine is an evolving filed which integrates multidisciplinary science in providing safe blood and blood products for patients. With an increasing demand for Transfusion Medicine training in Malaysia, a formal survey is needed to evaluate the postgraduate Transfusion Medicine programme offered by Advanced Med- ical and Dental Institute, Universiti Sains Malaysia to identify areas of deficiency based on the alumni experiences. Methods: An English language survey form was developed specifically to assess the programme contents (overall contents, learning experience in each year, and support in research), the alumni perception on soft-skills gained during the study, and the outcome of the programme. The survey forms were distributed to all alumni between March 2018 and October 2018 via e-mail or hand-delivered. Results: The survey response rate was 79% (37 of 47). A ma- jority (97%) of the transfusion medicine specialists (TMS) in this study reported that the course offered in the program was relevant to their current job. The learning experience which includes course content, student’s placement, facili- ties, and support in research) were rated between satisfactory and good. Communicating effectively through speaking was the highest reported soft-skill gained during the programme, whereas communicating effectively in writing was the lowest soft-skill gained. On the programme outcome, all TMS agreed that this programme will produce qualified and well trained specialists for current working market. Conclusion: Some improvement in the programme contents and teaching activities are needed to equip the future TMS for the nation.
The paramedic team of Advanced Medical and Dental Institute (IPPT), Universiti Sains Malaysia (USM) is often involved in providing medical assistance for various activities organised by the university such as during PIMPIN siswa outdoor training and sport events. Paramedics often faced difficulty in saving injured patients as the current stretcher is rather heavy (5.8 kg) and is not able to be folded to a smaller size. To overcome this problem, i-TAG, a stretcher made of durable two-layer canvas cloth with the size of 170.0 cm x 74.0 cm and equipped with 10 user-friendly rubber handle, has been invented. The upper part of the stretcher has a zip to insert the spinal board if the victim has spinal and head injuries. The i-TAG is also very light with only 1.2 kg in weight, easy to be folded and stored in emergency bags, and can be easily carried by paramedics. The i-TAG innovative product has a positive impact on health and safety services. Using i-TAG, the task to carry patients or injured victims becomes easier, faster, saves energy and subsequently increases the efficacy of the rescue and medical aid tasks by paramedics.
The paper discusses on the complexity of the issues surrounding a patient with subluxation of cervical spine in a Down syndrome child. Several relevant issues are discussed including consent in a minor, conflicting decision making between parents and doctors, end-of-life issues, supporting handicapped child with minimal co-morbidities, community ethics, neglect of care by the caregiver and decision making after allowing zonal of parental discretion. Despite the difficulties surrounding parental actions, there are still ethical priorities which have to be considered individually to alleviate the suffering of the patients and the family members. Dealing with patients with chronic illnesses is a challenge for any medical doctors. The case warrants sensitive approach to allow appropriate respect for parental decision despite in disagreement with the clinical team. The term ‘zone of parental discretion’ refers to a controversial area of decision making; and has still many potential conflicts on day to day clinical cases, especially among the conservative society in the East Coast of Peninsular Malaysia.
Infant feeding is thought to modulate cardiovascular risk factors such as obesity, hypertension, hyperglycemia, and dyslipidemia. This possible association between patterns of feeding with development of cardiovascular disease later in life provides the opportunity for early intervention and prevention strategies. Among all the feeding methods applied, breastfeeding is thought to be the best method and is said to be attributable to future health benefits. How- ever, current evidence from the literature is weak and inconsistent to advocate risk factors management. Therefore, this narrative review aims to provide current findings in assessing the association of breastfeeding pattern and risk of developing cardiovascular diseases later in life. We searched three databases (MEDLINE, PubMed and Google Scholar) from year 2000 to 11 July 2018. Findings on the association between breastfeeding and cardiovascular risk factors are equivocal, although positive trend of beneficial effects of breastfeeding in reducing risk of cardiovascular diseases in adulthood was reported in majority of the studies. Future research should address all limitations that were identified by previous studies such as bias of study design and heterogeneity of samples to establish the association between breastfeeding pattern and cardiovascular disease in later life.
