Acute hemolytic transfusion reaction following ABO-incompatible platelet transfusion: two case reports An ideal platelet transfusion should provide ABO identical platelet concentrate, and cross match compatibility is not routinely performed in the standard practices. However, ABO non identical platelet transfusions are not uncommon with the limited resources and short shelf life of platelet concentrate. Though rare, acute hemolytic transfusion reaction (AHTR) may occur following minor ABO-incompatible platelet transfusion. Here, we report two cases of thrombocytopenic patients (one child and one adult) type as Group B RhD positive and received Group O RhD positive platelet transfusions. Both patients experienced an AHTR evidenced by a drop in hemoglobin level, spherocytosis and small agglutinations on the blood film, and positive direct Coombs test. They were treated symptomatically, recovered and discharged well post-event without any morbidity. No anti-B isohemagglutinins titer were done to confirm the high titer of the antibody in the platelet donors. Our cases highlighted the importance of ABO-compatible platelet transfusion, especially to children and those vigilant groups of patients.

INTRODUCTION: Calreticulin (CALR) mutations in myeloproliferative neoplasms (MPN) have been reported to be key markers in the molecular diagnosis, particularly in patients lacking JAK2 V617F mutation. In most current reports, CALR mutations were analysed by either allele-specific PCR (AS-PCR), or the more expensive quantitative real-time PCR, pyrosequencing and next-generation sequencing. Hence, we report the use of an alternative method, the conformation sensitive gel electrophoresis (CSGE) for the detection of CALR mutations in BCR-ABL1-negative MPN patients.
METHODS: Forty BCR-ABL1-negative MPN patients' DNA: 19 polycythemia vera (PV), 7 essential thrombocytosis (ET) and 14 primary myelofibrosis (PMF), were screened for CALR mutations by CSGE. PCR primers were designed to amplify sequences spanning between exons 8 and 9 to target the mutation hotspots in CALR. Amplicons displaying abnormal CSGE profiles by electrophoresis were directly sequenced, and results were analysed by BioEdit Sequence Alignment Editor v7.2.6. CSGE results were compared with AS-PCR and confirmed by Sanger sequencing.
RESULTS: CSGE identified 4 types of mutations; 2 PMF patients with either CALR type 1 (c.1099_1150del52) or type 2 (c.1155_1156insTTGTC), 1 ET patient with nucleotide deletion (c.1121delA) and insertion (c.1190insA) and 1 PV patient with p.K368del (c.1102_1104delAAG) and insertion (c.1135insA) inframe mutations. Three patients have an altered KDEL motif at the C-terminal of CALR protein. In comparison, AS-PCR only able to detect two PMF patients with mutations, either type 1 and type 2.
CONCLUSION: CSGE is inexpensive, sensitive and reliable alternative method for the detection of CALR mutations in BCR-ABL1-negative MPN patients.

A deferral takes place when donors fail to meet the eligibility criteria for donating blood during their visit to a blood collection site. Deferral periods, which can be either permanent or temporary, are implemented to protect the well-being of both the donor and the recipient. This study aimed to investigate the frequency of deferrals and the various factors contributing to them. A retrospective analysis was conducted at the Transfusion Medicine Unit of Hospital Universiti Sains Malaysia (USM), utilizing data obtained from blood donors during the period from January 2022 to June 2023. The research included a cohort of 18,751 donors who visited our transfusion unit for blood donation. Data, including gender, age, and reasons for deferral, were collected by reviewing the records of donors who were deferred. Descriptive statistics were employed to analyze the data of deferral blood donors. Out of 18,751 blood donors, 3,533 (18.84%) were deferred, consisting of 1,267 males (35.86%) and 2,266 females (64.14%). The age group of 18-25 years accounted for the highest number, comprising 1,875 donors (53.07%). Among the deferred cases, 53.33% were first-time donors, followed by 25.28% regular donors and 21.40% lapsed donors. The deferral of blood donors resulted from various reasons. The most common cause of overall deferral among blood donors was low hemoglobin (38.33%), followed by upper respiratory tract infections (8.38%), chronic medical illness (7.08%), and high blood pressure (7.02%). Temporary deferrals were more prevalent than permanent deferrals, accounting for 91.57% of cases compared to 8.43% for permanent deferrals. Voluntary non-remunerative blood donors constitute the backbone for a safe and reliable blood supply in transfusion services. Utilizing a comprehensive database will enable effective counseling of temporarily deferred donors, providing insights into the reasons for their deferral, the expected duration, and the appropriate treatments. This information is crucial for motivating these donors to recruit again in the donor pool. Public education initiatives aimed at raising awareness about the causes of deferral and promoting regular health check-ups can play a pivotal role in minimizing these deferrals.

PMID: 33083035 DOI: 10.5001/omj.2020.95

Objectives: Red blood cell (RBC) immunization is a common complication in blood transfusion recipients. Patients with chronic kidney disease (CKD) eventually develop anemia, which is multifactorial, and requires regular blood transfusions, which exposes patients to the development of RBC antibodies. We sought to determine the prevalence and specificity patterns of RBC immunization and its risk factors among transfused CKD patients.
Methods: We conducted a cross-sectional study over one year from January to December 2018 in the Transfusion Medicine Unit, Hospital Universiti Sains Malaysia. A total of 249 samples were recruited from CKD patients who received a blood transfusion (at least one-pint), which only match for ABO and Rh(D) antigen. The serum was screened for the presence of the RBC antibody using the gel agglutination technique (Diamed gel cards). Samples with positive antibody screening were subjected to antibody identification.
Results: Of the 249 transfused CKD patients, 31 (12.4%) developed RBC immunization. Thirty (12%) were alloimmunized, and one (0.4%) was autoimmunized. Anti-Mia was the most common antibody (n = 14, 46.7%) among alloantibodies, followed by anti-E (n = 7, 23.3%). There was a significant association between pregnancy history with the development of antibodies whereas, no significant association was found between sociodemographic background, stage of CKD, hemodialysis status, underlying medical illness, and number of packed cell transfusions with the development of RBC antibodies.
Conclusions: One-eighth of our patient cohort had RBC alloimmunization, and the risk was increased in patients with a history of pregnancy. We propose Rhesus RBC phenotyping and to supply blood match Rhesus antigen in CKD patients, especially patients of reproductive age.

Hypertension is the most prevalent risk factor of cardiovascular diseases in Malaysia. 17.3% of hypertension cases in Malaysia is attributed to adults aged 18 to 39 years. Psychosocial distress is a possible risk factor for elevated blood pressure in young adults, and cortisol could be the mediating factor. The aim of this study is to evaluate the mediating role of cortisol in hypertension and psychosocial distress in young adults. Methods and materials:A comparative cross-sectional study was conducted in 240 young adults aged 18 to 45 years. The body mass index, waist circumference and blood pressure parameters were recorded. Serum cortisol, creatinine, fasting blood glucose and lipid profile were measured following acute mental stress test. Psychosocial distress was assessed using the DASS-21 questionnaire. Results:Mean (standard deviation) values for SBP, DBP, MAP were 126.0(16.3), 84.1(12.2) and 98.1(13.1) mmHg respectively. Anxiety was significantly associated with systolic blood pressure (β=0.644), diastolic blood pressure (β=0.454) and mean arterial pressure (β=0.516) after adjusting for sex, age and cortisol. However, it was not mediated by cortisol. Depression and stress were not found to have any effect on blood pressure of the young adults studied. Conclusion:The data suggest that there is no elevated risk for psychosocial distress and hypertension that cortisol poses in young adults.

Background of Study: Patients with thyroid disorders were found to have
continued to experience symptoms of depression despite the great of treatment has
been given to the patient to balance the thyroid hormones. Objective: The aim of
this study is to determine the level of depression symptoms among various types
of thyroid disorders patients.

Methods: A cross sectional study was carried out at
one of the government hospital at central region of Peninsular Malaysia from
August to October 2016. Patients were diagnosed as thyroid disorders, Malaysian
citizen, above 18 years old and did not have any psychiatric disorders were
included in this study.Depression Anxiety Stress Scale-42 (DASS-42) was
selected to determine the severity of depression symptoms and interpreted as
follow: less than 9-no depression, between 10 and 13-mild depression, between
14-20-moderate depression, between 21 and 27- severe depression and more than
28-extreme severe depression. Descriptive statistic was analysed by IBM
Statistical Package for the Social Sciences (SPSS) version 21.0.

Results: About
15% (23) out of 153 thyroid patients had varies degree of depression symptoms
from mild to severe extremely depression. Patients who had hyperthyroid were
found to have more depressed, followed by hypothyroid and thyroid cancer group.

Conclusion: These findings would suggest that the depression score was higher in
the patients who have hyperthyroid. A more detail and thorough study is
recommended to be done, in order to confirm these findings.

Siti Asmaa MJ, Miin Phoon L, Zakaria NA, Hussin S, Bahar R, Hassan MN, et al.

Cureus, 2024 Mar;16(3):e57353.
PMID: 38694420 DOI: 10.7759/cureus.57353

Background Hb Adana is a non-deletional alpha (α)-thalassaemia variant resulting from mutations in α1- or α2-globin codon 59 (αCD59), leading to the production of unstable α-globin. Clinical manifestations can vary from silent carrier status to dependence on blood transfusions, hepatosplenomegaly, skeletal deformities, and spinal cord compression. Despite the significance of Hb Adana inheritance, studying this variant poses challenges due to the scarcity of molecular tests and the potential for routine diagnoses to be overlooked. This study aims to investigate the prevalence of Hb Adana among local high school students and assess the hematological parameters and hemoglobin analysis of Hb Adana in Malaysia. Methodology This retrospective study analyzed 13,721 blood samples collected from high school students participating in Malaysia's National Thalassaemia Screening Program at Hospital Raja Perempuan Zainab II (HRPZ II). Deletional α-thalassaemia was detected using multiplex gap-polymerase chain reaction (PCR), while common non-deletional α-thalassaemia was identified using multiplex amplification refractory mutation system (ARMS) PCR. Data were extracted from the HRPZ II database for analysis. Results Among the participants, 2327 individuals were found to have either common deletional (n=1037, 44.6%) or non-deletional (n=1290, 55.4%) α-thalassaemia. Hb Constant Spring was the most prevalent non-deletional α-thalassaemia, accounting for 53.03% of cases. Thirty-one participants (1.33%) exhibited αCD59α/αα, and one (0.04%) had αCD59α/-α3.7. Among the 32 subjects with Hb Adana, 87.5% were Malay, and 12.5% were Orang Asli. Additionally, seven cases of HbE/Hb Adana co-inheritance were identified. Hemoglobin levels in heterozygous Hb Adana individuals ranged from mild anemia to normal, between 95 g/L and 153 g/L. Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were approximately 73 fL and 23 pg, respectively. Conclusion This study delineates the distribution of α-thalassaemia mutation patterns among high school students in Kelantan, Northeast Peninsular Malaysia. Our findings indicate that Hb Adana is rare in our region and co-inheritance with an α-gene deletion results in α+-thalassaemia and with HbE, α0-thalassaemia. All heterozygous Hb Adana individuals exhibited low MCVs and MCHs.

Said MA, Hatim A, Habil MH, Zafidah W, Haslina MY, Badiah Y, et al.

Prev Med, 2013;57 Suppl:S50-3.
PMID: 23337566 DOI: 10.1016/j.ypmed.2013.01.005

OBJECTIVE: The objective of this study is to determine the prevalence of metabolic syndrome among schizophrenia patients receiving antipsychotic monotherapy in Malaysia.
METHOD: A cross-sectional study was conducted at multiple centres between June 2008 and September 2011. Two hundred and five patients who fulfilled the DSM IV-TR diagnostic criteria for schizophrenia and who had been on antipsychotic medication for at least one year, were screened for metabolic syndrome. Patients receiving a mood stabilizer were excluded from the study. Metabolic syndrome was defined by using the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults Treatment Panel III (ATP III) modified for Asian waist circumference.
RESULTS: In the first-generation antipsychotic (FGA) group, the highest prevalence of metabolic syndrome was among patients treated with trifluoperazine and flupenthixol decanoate (66.7% each). For the second-generation antipsychotic (SGA) group, the highest prevalence of metabolic syndrome was among patients treated with clozapine (66.7%). The component with the highest prevalence in metabolic syndrome was waist circumference in both FGA and SGA groups except for aripiprazole in SGA.
CONCLUSION: The prevalence of metabolic syndrome in schizophrenia patients receiving antipsychotic monotherapy in Malaysia was very high. Intervention measures are urgently needed to combat these problems.

Red blood cell (RBC) alloimmunization is an important complication of blood transfusion. Variations in the frequency of alloimmunization have been noted among different patient populations. We aimed to determine the prevalence of RBC alloimmunization and associated factors among chronic liver disease (CLD) patients in our center. This is a case-control study involving 441 patients with CLD who were being treated at Hospital Universiti Sains Malaysia and subjected to pre-transfusion testing from April 2012 until April 2022. Clinical and laboratory data were retrieved and statistically analyzed. A total of 441 CLD patients were included in our study, with the majority being elderly, with the mean age of patients 57.9 (SD ± 12.1) years old, male (65.1%) and Malays (92.1%). The most common causes of CLD in our center are viral hepatitis (62.1%) and metabolic liver disease (25.4%). Twenty-four patients were reported to have RBC alloimmunization, resulting in an overall prevalence of 5.4%. Higher rates of alloimmunization were seen in females (7.1%) and patients with autoimmune hepatitis (11.1%). Most patients developed a single alloantibody (83.3%). The most common alloantibody identified belonged to the Rh blood group, anti-E (35.7%) and anti-c (14.3%), followed by the MNS blood group, anti-Mia (17.9%). There was no significant factor association of RBC alloimmunization among CLD patients identified. Our center has a low prevalence of RBC alloimmunization among CLD patients. However, the majority of them developed clinically significant RBC alloantibodies, mostly from the Rh blood group. Therefore, phenotype matching for Rh blood groups should be provided for CLD patients requiring blood transfusions in our center to prevent RBC alloimmunization.

Introduction: Lack of knowledge and negative attitude towards HIV/AIDS may be the risk factors for HIV infection among transsexuals. Research on knowledge and attitude towards HIV infection in transsexual communities is very limited at both local and international levels. This study aimed to assess the knowledge and attitude towards HIV infection among the male-to-female transsexual community in Kuantan, Pahang.
Methods: A cross-sectional study was carried out from July to August 2014 among 33 male-to-female transsexuals in Kuantan, Pahang. Convenience sampling was used. Participants who gave consent answered a self-administered questionnaire. Data obtained was analyzed with descriptive statistics, χ2-test, and independent sample t test.
Results: The majority of the subjects in this study were 29 years and below (48.5%), Muslims (93.9%), and had completed up to secondary education (60.6%). Most of them were sex workers (60.6%), and had relatively low income (no income to RM 3000, mean of RM1528). A total of 87.9% of the subjects demonstrated good knowledge and also positive attitude towards HIV/AIDS. Level of education was significantly associated with scores in knowledge (p=0.01).
Conclusions: Despite the positive outcome from this study, misconceptions towards HIV/AIDS still exist among transsexuals. Education and interventions from multiple directions on HIV/AIDS are essential to deliver the correct information to this population, so as to emphasize prevention, early detection, and holistic medical care. Transsexuals also require attention from religious bodies and non-governmental organizations to help them in employment, financial, spiritual, and psycho-social issues.

Background: Having a validated questionnaire in any field would nurture a research path in that particular area. The aim of this study was to validate the Depression Anxiety Stress Scales 21-item (DASS-21) Bahasa Malaysia (BM) version among clinical subjects who were diabetic patients. Objectives: To determine the reliability and construct validity of the BM DASS by looking at internal consistency and exploratory factor analysis respectively. Methods: The BM DASS was administered to a total of 153 diabetic patients. These patients were selected when they came to 15 retail pharmacies all over the Klang Valley. Results: The BM DASS-21 had very good Cronbach’s alpha values of 0.75, 0.74 and 0.79, respectively for depression, anxiety and stress subscales. For construct validity, it also had good factor loading values for 17 out of 21 items (.31 to .75). Conclusions: The results of this study entrenched the evidence that the BM DASS-21 had excellent psychometric properties and therefore it is suitable to be used for the Malaysian clinical population.

Introduction: As eating disorders such as anorexia nervosa and others are generally becoming more prevalent, it is essential to have a culturally accepted and locally validated questionnaire that is able to detect abnormal eating habits. Objective: To translate the Eating Disorders Examination Questionnaire (EDE-Q) into Bahasa Malaysia (BM) and to determine the construct validity, reliability and other psychometric properties of the BM version. Method: Two parallel forward and backward translations were done in BM in accordance to guideline. Its validation was determined by using confirmatory factor analysis among 298 secondary school children. Results: The BM EDE-Q had very good internal consistency with global Cronbach’s alpha value of 0.879. For construct validity, majority of the items managed to produce values of more than 0.4 for confirmatory factor analysis with four unforced distinct factors detected. Conclusions: Analyses of reliability and validity of this BM version of EDE-Q yielded satisfactory results. The BM version produced in this study had good psychometric properties and it is applicable to the Malaysian population. Findings indicated that cultural factors in eating habits certainly influences the effort to adapt the questionnaire within a Malaysian setting.

Introduction: There is an appealing need to have a validated Bahasa Malaysia (BM) questionnaire that is able to gauge stress coping styles among Malaysian population. A culturally accepted questionnaire will generate further research in the aspect of stress coping patterns in the Malaysia population. Objective: To translate the Coping Inventory for Stressful Situations (CISS) questionnaire into BM and to determine the construct validity, reliability and other psychometric properties of the translated BM version of the English CISS 48-item. Method: Two parallel forward and backward translations were done in BM in accordance to guideline and its validation was determined by using confirmatory factor analysis among 200 Malaysian subjects. Results: The BM CISS had very good Cronbach’s alpha values, 0.91, 0.89 and 0.85 respectively for Task-, Emotional- and Avoidance-oriented. The overall Cronbach’s alpha was 0.91. It also had good factor loading for most of its items where 44 items out of 48 had Confirmatory Factor Analysis values of more than 4.0. Conclusions: BM CISS had been adequately and correctly translated into Bahasa Malaysia with high psychometric properties. Minimal readjustment may be required in a few of its items to obtain excellent results.

Background: The Malay short version of Depressive Anxiety and Stress Scale (DASS-21) has been widely used as a tool to measure psychological parameters in studies in Malaysia. The version has been found to be reliable for clinical and non-clinical populations. Objectives: To analyse and establish the psychometric properties of the Malay version of the DASS 42-item (BM DASS-42) among medical students. Methods: Concurrent forward and backward translations of original English DASS-42 were completed. Construct validity of the DASS-42 was established by looking at its exploratory factor analysis. Malay DASS-42 and Malay HADS were administered to a total of 411 medical students. Results: Reliability of DASS-
42 revealed excellent Cronbach’s alpha values of 0.94, 0.90 and 0.87 for depressive, anxiety and stress domains respectively. Construct validity yielded 38 items out of 42 items (90%) had good factor loadings of 0.4 and more. DASS and HADS were strongly correlated for both anxiety (r=0.87) and depression (r=0.68) domains. Conclusions: The BM DASS-42 had admirable psychometric properties among the tested population. Further studies are needed to verify these preliminary outcomes in other Malaysian subjects.

Wolfram syndrome (WFS) is a rare neurodegerative disorder which is characterized by presentation of diabetes insipidus, juvenile diabetes mellitus, optic atrophy and deafness. We describe a case of WFS with presentation of psychosis. A 17-year-old female presented with psychiatric manifestations, namely inappropriate behaviour and second person auditory hallucination since the age of 16 years. The patient was diagnosed with type 1 diabetes mellitus at the age of 10 years old and subsequently progressive hearing and visual loss a year later. Her ophthalmic evaluation revealed total blindness due to optic atrophy. However she did not have renal dysfunction and diabetes insipidus which are also features of the syndrome. There is scarce literature to describe on psychiatric presentation in WFS. In the past, the psychiatric manifestation which was reported most of times was mood and suicidal behaviour. Hardly any article reported about psychosis (hallucination). We believe, her psychiatric manifestations were related to sensory deprivation due to blindness and deafness caused by the progression of WFS.

PMID: 18387090 DOI: 10.1111/j.1750-3841.2007.00657.x

High-oleic palm oil (HOPO) with an oleic acid content of 59.0% and an iodine value (IV) of 78.2 was crystallized in a 200-kg De Smet crystallizer with a predetermined cooling program and appropriate agitation. The slurry was then fractionated by means of dry fractionation at 4, 8, 10, 12, and 15 degrees C. The oil and the fractionated products were subjected to physical and chemical analyses, including fatty acid composition, triacylglycerol and diacylglycerol composition, solid fat content, cloud point, slip melting point, and cold stability test. Fractionation at 15 degrees C resulted in the highest olein yield but with minimal oleic acid content. Due to the enhanced unsaturation of the oil, fractionation at relatively lower crystallization temperature showed a considerable effect on fatty acid composition as well as triacylglycerol and diacylglycerol composition of liquid fractions compared to higher crystallization temperature. The olein and stearin fractionated at 4 degrees C had the best cold stability at 0 degrees C and sharper melting profile, respectively.

PMID: 23770945 MyJurnal

The escalating problem of opiate dependence in Malaysia and the limitations of regimental approach of forced admission to rehabilitation centres had triggered the government to expand the methadone maintenance therapy to become a national programme. This study aimed to evaluate the short-term outcomes of the Methadone Maintenance Therapy programme in one of the busiest hospital in east coast Malaysia. We also explored the prevalence on non-compliance and factors associated to it. A total of 172 patient case notes at Methadone Clinic Hospital Tengku Ampuan Afzan (HTAA) were retrieved for relevant data. A short survey was also conducted to determine the subjects' current employment and marital status. The programme's retention rate was 62% and factors associated with poor compliance were unemployment, low quality of life scores and low dose of methadone. A special attention on the patients with these three risk factors may improve their compliance to MMT. The short-term evaluation of MMT at HTAA revealed favourable findings.

PMID: 25606241 MyJurnal

OBJECTIVE: To analyse the features of patients with vaginismus first presented to a gynaecologist for infertility before being referred for psychiatric evaluation and management. The case series aim to provide some insight on features and presentations of Asian women with vaginismus. Vaginismus is characterised by persistent or recurrent difficulties in vaginal penetration despite the woman's wish for coitus. Avoidance, phobia, anticipatory fear of pain and involuntary pelvic muscle contraction are the most common symptoms.

METHOD: We report a series of cases of Malaysian women who had been suffering from vaginismus and 'infertility'. All the cases had never been attended to medically and there were long delays in seeking intervention. There was no history of traumatic sexual experience or any major psychiatric illness in these patients. Majority of the patients had prominent symptoms of anxiety.

CONCLUSION: The cases illustrate that it is important to rule out the possibility of vaginismus among patients with infertility. The former have unique psychological features which require psychological interventions.

BACKGROUND: High prevalence of high-risk behaviours and concurrent medical illnesses among opioid drug users would influence the outcome of Methadone Maintenance Programme. It would also require a special medical attention to contain these issues.
OBJECTIVES: This study explored patients' characteristics and their high-risk behaviours in order to understand more about opioid dependent users in Malaysia.
METHODS: A total of 172 patient case notes at Methadone Clinic Hospital Tengku Ampuan Afzan (HTAA) were retrieved for relevant data.
RESULTS: Many of the patients were engaged in high-risk behaviours such as needle sharing, unsafe sex and criminal activities. A large number of the subjects had contracted blood-borne diseases such as HIV and hepatitis infections.
CONCLUSIONS: Education on the issue of medical and psychosocial complications related to high risk behaviours is essential. Medical professionals dealing with this group have to pay attention and update their knowledge on the medical issue.

A new organic-inorganic nanohybrid based on zinc-layered hydroxide intercalated with an anti-inflammatory agent was synthesized through direct reaction of salicylic acid at various concentrations with commercially available zinc oxide. The basal spacing of the pure phase nanohybrid was 15.73 Å, with the salicylate anions arranged in a monolayer form and an angle of 57 degrees between the zinc-layered hydroxide interlayers. Fourier transform infrared study further confirmed intercalation of salicylate into the interlayers of zinc-layered hydroxide. The loading of salicylate in the nanohybrid was estimated to be around 29.66%, and the nanohybrid exhibited the properties of a mesoporous-type material, with greatly enhanced thermal stability of the salicylate compared with its free counterpart. In vitro cytotoxicity assay revealed that free salicylic acid, pure zinc oxide, and the nanohybrid have a mild effect on viability of African green monkey kidney (Vero-3) cells.
