    Chronic Myeloid Leukemia (CML) is a clonal disorder thought to originate in a single abnormal haematopoietic stem cell. This myeloproliferative fatal stem cell disorder comprises
    approximately 14% of all leukemias. In most cases, CML runs a triphasic course, which includes an initial chronic phase that transforms eventually into a blastic phase resembling acute leukemia. In 60%- 80% of patients, an intermediate or accelerated phase precedes the terminal blastic phase. Accelerated phase and blastic phase sometimes are lumped together and considered to be
    advanced phase CML. The entire continuum from chronic phase to blastic phase lasts a median of 3 to 5 years . This time period can be broken down in to the chronic phase which if untreated,
    lasts for 2 to 5 years and finally the fatal blastic phase, which lasts from 3 to 6 months. A patient can present in any of these 3 stages.

    This study concerns the role of activated carbon (AC) from palm raceme as a support material for the enhancement of lipase-catalyzed reactions in an aqueous solution, with deep eutectic solvent (DES) as a co-solvent. The effects of carbonization temperature, impregnation ratio, and carbonization time on lipase activity were studied. The activities of Amano lipase from Burkholderia cepacia (AML) and lipase from the porcine pancreas (PPL) were used to investigate the optimum conditions for AC preparation. The results showed that AC has more interaction with PPL and effectively provides greater enzymatic activity compared with AML. The optimum treatment conditions of AC samples that yield the highest enzymatic activity were 0.5 (NaOH (g)/palm raceme (g)), 150 min, and a carbonization temperature of 400 °C. DES was prepared from alanine/sodium hydroxide and used with AC for the further enhancement of enzymatic activity. Kinetic studies demonstrated that the activity of PPL was enhanced with the immobilization of AC in a DES medium.

    Background: Banks and financial institutions are vulnerable to money laundering (ML) as a result of crime proceeds infiltrating banks in the form of significant cash deposits. Improved financial crime compliance processes and systems enable anti-ML (AML) analysts to devote considerable time and effort to case investigation and process quality work, thereby lowering financial risks by reporting suspicious activity in a timely and effective manner. This study uses Job Characteristics Theory (JCT) to evaluate the AML system through the job satisfaction and motivation of its users. The purpose of this study is to determine how satisfied AML personnel are with their jobs and how motivated they are to work with the system. Methods: This cross-sectional study used JCT to investigate the important elements impacting employee satisfaction with the AML system. The five core dimensions of the job characteristics were measured using a job diagnostic survey. The respondents were employees working in the AML department of a Malaysian bank, and the sample group was chosen using a purposive sampling approach. A total of 100 acceptable replies were gathered and analysed using various statistical approaches. A motivating potential score was generated for each employee based on five main job characteristics. Results: Findings revealed that five core job characteristics, namely, skill diversity, task identity, task importance, autonomy and feedback, positively influence the AML system employees' job satisfaction. However, skill variety and autonomy are found to be low, which are reflected in the poor motivating potential score. Conclusion: This study examined the characteristics of the AML system and its users' job satisfaction. Findings revealed that task significance is the most widely recognised characteristic, followed by feedback and task identity. However, there is a lack of skill variety and autonomy, which must be addressed to improve employee satisfaction with the AML system.

    Children with Down syndrome (DS) are at a significantly higher risk of developing acute myeloid leukemia, also termed myeloid leukemia associated with DS (ML-DS). In contrast to the highly favorable prognosis of primary ML-DS, the limited data that are available for children who relapse or who have refractory ML-DS (r/r ML-DS) suggest a dismal prognosis. There are few clinical trials and no standardized treatment approach for this population. We conducted a retrospective analysis of international study groups and pediatric oncology centers and identified 62 patients who received treatment with curative intent for r/r ML-DS between year 2000 to 2021. Median time from diagnosis to relapse was 6.8 (range, 1.1-45.5) months. Three-year event-free survival (EFS) and overall survival (OS) were 20.9 ± 5.3% and 22.1 ± 5.4%, respectively. Survival was associated with receipt of hematopoietic stem cell transplantation (HSCT) (hazard ratio [HR], 0.28), duration of first complete remission (CR1) (HR, 0.31 for > 12 months) and attainment of remission after relapse (HR, 4.03). Patients who achieved complete remission (CR) before HSCT, had an improved OS and EFS of 56.0 ± 11.8% and 50.5 ± 11.9%, respectively compared to those who underwent HSCT without CR (3-year OS and EFS of 10.0 ± 9.5%). Treatment failure after HSCT was predominantly because of disease recurrence (52%) followed by treatment-related mortality (10%). The prognosis of r/r ML-DS remains dismal even in the current treatment period and serve as a reference point for current prognostication and future interventional studies. Clinical trials aimed at improving the survival of patients with r/r ML-DS are needed.

    This study aims to systematically review prior research on the evaluation and benchmarking of automated acute leukaemia classification tasks. The review depends on three reliable search engines: ScienceDirect, Web of Science and IEEE Xplore. A research taxonomy developed for the review considers a wide perspective for automated detection and classification of acute leukaemia research and reflects the usage trends in the evaluation criteria in this field. The developed taxonomy consists of three main research directions in this domain. The taxonomy involves two phases. The first phase includes all three research directions. The second one demonstrates all the criteria used for evaluating acute leukaemia classification. The final set of studies includes 83 investigations, most of which focused on enhancing the accuracy and performance of detection and classification through proposed methods or systems. Few efforts were made to undertake the evaluation issues. According to the final set of articles, three groups of articles represented the main research directions in this domain: 56 articles highlighted the proposed methods, 22 articles involved proposals for system development and 5 papers centred on evaluation and comparison. The other taxonomy side included 16 main and sub-evaluation and benchmarking criteria. This review highlights three serious issues in the evaluation and benchmarking of multiclass classification of acute leukaemia, namely, conflicting criteria, evaluation criteria and criteria importance. It also determines the weakness of benchmarking tools. To solve these issues, multicriteria decision-making (MCDM) analysis techniques were proposed as effective recommended solutions in the methodological aspect. This methodological aspect involves a proposed decision support system based on MCDM for evaluation and benchmarking to select suitable multiclass classification models for acute leukaemia. The said support system is examined and has three sequential phases. Phase One presents the identification procedure and process for establishing a decision matrix based on a crossover of evaluation criteria and acute leukaemia multiclass classification models. Phase Two describes the decision matrix development for the selection of acute leukaemia classification models based on the integrated Best and worst method (BWM) and VIKOR. Phase Three entails the validation of the proposed system.

    Young adult survivors of childhood leukemia have been reported with increased likelihood of age-related comorbidities compared with the general population. We compared the prevalence of frailty in young adult survivors of childhood acute lymphoblastic leukemia (n=58, median age=23 y, median survival time=18 y) with age-matched and sex-matched controls without history of cancer. Frailty phenotypes were determined using Fried frailty model. Association between frailty status and cardiometabolic conditions, systemic inflammation, and T-cell immunophenotype changes were also examined. Frailty and prefrailty were more common among survivors compared with controls (58.6% vs. 34.5%, P =0.019). Physical inactivity (39.7%) was the most frequently observed frailty criterion among the survivors. Prevalence of cardiometabolic conditions was comparable between the robust and frail/prefrail survivors. Robust survivors had a higher level of T-cell activation than the prefrail/frail survivors ( P <0.05), but no significant difference was observed for systemic inflammatory markers (IL-6 and C-reactive protein) and percentage of terminally differentiated T cells. Signs of frailty, especially physical inactivity, was detected in childhood acute lymphoblastic leukemia survivors early in their third decade of life. Survivors who were prefrail/frail also had altered T-cell activation; however, the role of such changes in T-cell phenotype in the etiology of frailty warrant further investigation.

    We report a case of bone marrow necrosis preceding infantile acute lymphoblastic leukaemia (ALL). Bone marrow necrosis is a rare antemortem event and has been known to be present in many conditions, notably in haematological malignancies like acute lymphoblastic leukaemia. This case was a 6-month-old Chinese boy who was referred to Hospital Universiti Kebangsaan Malaysia for further investigation of pancytopaenia, high-grade fever, bloody diarrhoea and petechial rashes for one week. His first bone marrow aspirate revealed bone marrow necrosis. His clinical condition improved after ten days. However, his full blood picture then revealed the presence of 5% blast cells. His subsequent marrow 2 weeks later revealed acute lymphoblastic leukaemia (FAB-L1) and immunophenotyping showed precursor B acute lymphoblastic leukaemia-null type. He was started on United Kingdom Acute Lymphoblastic leukaemia (UK ALL) Infantile Leukaemia protocol, however, he defaulted treatment after 3 days. Mode of presentation, mechanism of disease and laboratory investigations and outline of treatment will be discussed.

    Chronic Myeloid Leukaemia (CML) is a disease characterised by a distinctive marker that is the Philadelphia Chromosome and an ability to transform into blast phase, which confers a poor prognosis. The median survival was reported to be between three to six months in correlation to blast phase. Extramedullary involvement with CML to sites such as pleural, meningeal and bones have been reported. We report a case of 41-year-old man who was diagnosed with CML in blast phase and presented with ascites. Ultrasound of abdomen showed coarse echotexture of liver suggestive leukaemic infiltration to the liver. The liver profile was severely deranged and associated with coagulopathy. Flow cytometry analysis of the peritoneal fluid revealed presence of myeloblasts consistent with CML in blast crisis with leukaemic ascites. Bone marrow biopsy also confirmed disease transformation. He received standard induction chemotherapy for acute myeloid leukaemia with dose modifications based on liver enzymes performance. Our case highlights an unusual presentation of CML in blast crisis with leukaemic ascites and the challenges in managing cytotoxic treatments due to the liver infiltration.

    INTRODUCTION: Regulation in adaptive immune response balances a fine line that prevents instigation of self-damage or fall into unresponsiveness permitting abnormal cell growth. Mechanisms that keep this balance in check include regulatory T cells (Tregs). Tregs consist of a small but heterogeneous population, which may be identified by the phenotype, CD3+CD4+CD25+CD127-. The role of Tregs in pathogenesis of cancers is thus far supported by evidence of increased Tregs in various cancers and may contribute to poorer prognosis. Tregs may also be important in acute leukaemias.

    OBJECTIVE: A review of the literature on Tregs in acute leukaemias was conducted and Tregs were determined in B-cell acute lymphoblastic leukaemias (ALLs).

    RESULTS: Studies on Tregs in B-cell ALL are few and controversial. We observed a significantly increased percentage of Tregs (mean±SD, 9.72 ± 3.79% vs. 7.05 ± 1.74%; P = 0.047) in the bone marrow/peripheral blood of ALL (n = 17) compared to peripheral blood of normal controls (n = 35). A positive trend between Tregs and age (R = 0.474, P = 0.055, n = 17) implicates this factor of poor prognosis in B-cell ALL.

    DISCUSSION: Tregs in cancer are particularly significant in immunotherapy. The manipulation of the immune system to treat cancer has for a long time ignored regulatory mechanisms inducible or in place. In lymphoma studies, tumour-specific mechanisms that are unlike conventional methods in the induction of Tregs have been hypothesized. In addition, tumour-infiltrating Tregs may present different profiles from peripheral blood pictures. Tregs will continue to be dissected to reveal its mysteries and their impact on clinical significance.

    The variant form of acute promyelocytic leukaemia (AML-M3) possesses its own characteristic morphology, although usually a few of the cells may have cytoplasmic features of typical AML-M3. In contrast to typical AML-M3, this M3-variant form commonly presents with hyperleucocytosis. As in typical AML-M3, disseminated intravascular coagulopathy (DIVC) occurs in the M3-variant. A boy with this morphological variant of AML-M3 is described. Uncharacteristically, his presenting white blood count was low, and DIVC was present before treatment was started. Six days into intensive chemotherapy his coagulopathy worsened and he subsequently died of intracranial haemorrhage. An alternative approach to the treatment of AML-M3, with the use of retinoids, is discussed.

    Immunophenotyping of acute leukaemias has become an important diagnostic tool in haematology laboratories as it is now well recognised that the presence of certain surface markers has prognostic significance. In 1988, we experimented with the alkaline phosphatase anti-alkaline phosphatase (APAAP) method for immunophenotyping of leukaemic cells in our laboratory. 48 cases of peroxidase-negative acute leukaemias were studied. Our study showed that 2 peroxidase-negative cases carried myeloid surface markers, 44% were negative for the markers studied and 5% were unclassified due to technical problems. We concluded that the APAAP method is a useful technique for demonstrating cell markers in leukaemic cells as the reaction is reddish and usually intense. We failed to demonstrate surface markers in 44% of the cases probably because of the choice of a limited panel of monoclonal antibodies.

    Doxorubicin (DOX) adalah salah satu ubat kemoterapi yang paling berkesan untuk merawat pelbagai neoplasma seperti leukemia, limfoma dan kanser payudara. Walau bagaimanapun, ia sering dikaitkan dengan kardiomiopati. Pada masa ini, tiada rawatan yang sesuai untuk mengurangkan kesan kardiomiopati tanpa kesan sampingan yang ketara. Oleh itu, kajian ini bertujuan untuk mengkaji kesan-kesan perlindungan potensi ekstrak benih padi (RSE) terhadap kesitotoksikan yang disebabkan oleh DOX menggunakan kajian kultur sel vitro. Keupayaan antioksidan RSE dinilai, dan hasilnya menunjukkan jumlah kandungan fenolik yang lebih rendah (TPC), tetapi jumlah kandungan flavonoid total (TFC) dan kapasiti antioksidan yang setara trolox (TEAC), dibandingkan dengan ekstrak benih wheatgrass. Satu siri eksperimen spektroskopi penyerapan dan pendarfluor menunjukkan bahawa RSE boleh menghalang pembentukan kompleks DOX-DNA pada kepekatan yang diuji. Tambahan pula, daya maju sel kardiomiosit sel, H9c2 (2-1), telah diuji selepas 24, 48 dan 72 jam rawatan DOX terhadap RSE menggunakan ujian proliferasi sel berdasarkan garam tetrazolium (MTS reagent). Hasilnya menunjukkan kesan perlindungan yang signifikan terhadap RSE terhadap kesitotoksikan yang disebabkan oleh DOX. Jalur sel karsinoma nasofarinks, HK1, digunakan sebagai kawalan untuk menentukan sama ada keberkesanan DOX terjejas oleh pentadbiran bersama RSE. Hasilnya tidak menunjukkan kesan negatif terhadap keberkesanan dadah. Pelbagai sifat berfaedah RSE menunjukkan potensi kuatnya untuk membangunkan agen kardioprotektif untuk melengkapi rawatan DOX dalam tetapan klinikal.

    BACKGROUND: In exploring the cause of Imatinib Mesylate (IM) resistance among Chronic Myeloid Leukemia (CML) patients who do not harbor BCR-ABL dependent mechanism, BCR-ABL independent pathways are the most probable pathways that should be explored. In BCR-ABL independent pathway, SOCS1 plays an important role as it helps in regulating optimal JAK/STAT activity.

    OBJECTIVE: To identify the association of SOCS1 gene hypermethylation in mediating IM Resistance.

    METHOD: The SOCS1 promoter methylation level of 92 BCR-ABL non mutated IM resistant CML patients, 83 IM good response CML patients and 5 normal samples from healthy individuals were measured using Methylation Specific-High Resolution Melt (MS-HRM) analysis.

    RESULTS: Both primers used to amplify promoter region from -333 to -223 and from -332 to -188 showed less than 10% methylation in all CML and normal samples. Consequently, there was no significant difference in SOCS1 promoter methylation level between IM resistant and IM good response patients.

    CONCLUSION: SOCS1 promoter methylation level is not suitable to be used as one of the biomarkers for predicting the possibility of acquiring resistance among CML patients treated with IM.

    Acute myeloid leukaemia (AML) is the most common subtype of acute leukaemias with a poor outcome. Msi2 protein is a newly discovered prognostic marker and it has been considered as a new target for therapy in AML. The study of Msi2
    protein expression in AML cases has not been performed in Malaysia, to date. The main aim of the present study was to observe the expression of Msi2 protein in AML patients by immunohistochemistry (IHC) and to correlate its expression
    with the well-established prognostic and clinical parameters in AML as well as the overall survival (OS). Sixty four bone marrow trephine biopsy sections were immunostained for Msi2 protein. The percentage of blasts with positive reaction
    and the intensity of the cytoplasmic and nuclear staining were evaluated. The expression of Msi2 protein was found in 95.3% cases with Msi2 pattern varying between the cases. In 71.9% of cases, the blasts showed total cellular positivity and 23.4% cases showed only cytoplasmic positivity. Majority showed high expression of Msi2 for cytoplasmic staining. Interestingly, there was significant correlation between total cellular staining and the intermediate cytogenetic subgroup (P=0.04). In conclusion, the results showed that the majority of the patients had high expression of Msi2 but this did not correlate to OS. However, the Msi2 expression correlated to the cytogenetic findings. The results suggest future extensive research to be conducted in order to ascertain the exact role of Msi2 positive blast cells in AML in our population and their association with prognosis and outcome.

    Chronic neutrophilic leukaemia is a rare myeloproliferative disease characterised by splenomegaly, sustained neutrophilia, raised vitamin B12 level and absence of the Philadelphia chromosome. We report a 74-year-old man who presented first with Sweet's syndrome and subsequently leukocytosis. He had splenomegaly, a raised vitamin B12 level, serum uric acid and neutrophil alkaline phosphatase score. Cytogenetic study of the marrow was normal and peripheral blood for BCR-ABL gene transcript was not detectable. He subsequently passed away with bronchopneumonia.

    A 13 year review at the University Hospital, Kuala Lumpur reveals that chronic myeloid leukaemia (CML) constitutes 4.3% of all childhood leukaemia. Adult type of CML occurs in older children and is associated with marked splenomegaly, leukocytosis and thrombocytosis and the presence of Philadelphia chromosome. Although the initial response to busulphan was encouraging most of the patients succumbed; 2 patients underwent acute lymphoblastic transformation. Juvenile CML occurs in younger children and is associated with less marked splenomegaly, leukocytosis and thrombocytopenia and the presence of elevated fetal haemoglobin levels. The disease is characterised by an acute fulminating course. Despite improved survival in acute lymphoblastic leukaemia, the outlook for chronic myeloid leukaemia in childhood remains poor and treatment needs re-evaluation.
