Fulltext Neurological recovery in a patient with recurrent aggressive giant cell tumour of the axis--a case report

Razak MA, Fazir M

Med J Malaysia, 2000 Sep;55 Suppl C:97-100.
PMID: 11200052

A rare case of an aggressive recurrent giant cell tumour of axis is presented. The problems encountered in diagnosis and management are discussed. High dose dexamethasone was found to be useful managing this inoperable aggressive tumour which was compressing the cord. Early diagnosis would facilitate wide excision of the tumour with good prognosis.
Fulltext HUKM instrumentation system in surgical treatment of adolescent idiopathic scoliosis--an early experience

Razak MA, Fazir M, Ibrahim S

Med J Malaysia, 2000 Sep;55 Suppl C:2-8.
PMID: 11200040

Between May 1992 through October 1998, twenty-two patients who had adolescent idiopathic scoliosis were treated using Universiti Kebangsaan Malaysia (UKM) spinal instrumentation and fusion. The minimum length of follow-up was 2 years with an average of 2.9 years. Nineteen patients were female and three patients were male. The mean age at the time of the operation was 16.2 years (range, 13 to 24 years). The average blood loss was 1,878 ml and the average operating time was 291 minutes. The mean pre-operative curve was 61.2 degrees, with a range of 40 degrees to 90 degrees. The average post-operative correction of the Cobb's angle was 53.5 per cent, with a range of 33 per cent to 81 per cent. Post-operative immobilization consisted of a maximum of six months in a body cast. There were no neurological injuries, no deep wound infections, and no evidence of pseudoarthroses. Only three complications occurred and these did not disturb the progress of the fusion. This technique safely achieves the objectives of scoliosis correction, and is cost-effective in the treatment of adolescent idiopathic scoliosis.
Fulltext The surgical outcome of degenerative lumbar spinal stenosis

Razak MA, Ong KP, Hyzan Y

Med J Malaysia, 1998 Sep;53 Suppl A:12-21.
PMID: 10968178

A retrospective study was conducted to assess the surgical outcomes of degenerative lumbar spinal stenosis. Twenty-five patients treated with decompressive surgery in Hospital Kuala Lumpur between January 1992 and August 1996 were reviewed. There were seven males and eighteen females. The average age was 51 years old (range 33 to 64 years old). The diagnosis of degenerative spinal stenosis was made based on the clinical features and was confirmed by radiographic findings. Ninety two percent of the patients had moderate to severe symptoms preoperatively. The types of surgery consisted of laminectomy (n = 15), laminotomy (n = 10), and laminoplasty (n = 1). The surgical outcomes were assessed based on patients' own assessment of symptoms relieved and functional returned to daily activities at least six months after the surgery. The average follow-up period was fifteen months (range 6 months to 42 months). Of these twenty-five patients, 4 (16%) claimed to have excellent results, 11 (44%) had good results, 8 (32%) reported fair, and 2 (8%) judged their surgical treatment as poor with little or no use. There was no anaesthetic, cardiovascular, or thromboembolic complications seen in this study. Four patients had recurrent claudication, one demonstrated localised arachnoiditis, and two had lumbar instability which were not documented preoperatively. One patient had L4 nerve root avulsion with dura torn and another patient had superficial wound infection. We concluded in this study that decompressive surgery offers satisfactory results in patients with moderate to severe degenerative spinal stenosis in short term follow-up.

Tan WC, Ong CK, Kang SC, Razak MA

Med J Malaysia, 2007 Jun;62(2):143-6.
PMID: 18705448 MyJurnal

First line Anti-TB therapy with rifampicin, isoniazid, pyrazinamide, and ethambutol/streptomycin is very effective. However, major adverse reactions to antituberculous drugs can cause significant morbidity and mortality. Cutaneous adverse drug reaction (CADR) is one of the commonly observed major adverse events. This retrospective study looked at the cases of TB treated in Respiratory Unit, Penang Hospital from January 2004 to December 2005. Of 820 patients treated for active TB, 47 patients (25 females; 22 males) developed CADR (5.7%). CADRs observed include morbiliform rash (72.3%), erythema multiforme syndrome (8.5%), urticaria (8.5%) and others (which include exfoliative dermatitis and lichenoid eruption). Ninety-seven percent of events occurred within two months after the initial dose. Incidence rate of CADR among the first line anti-TB drugs, pyrazinamide was the commonest offending drug (2.38%), followed by streptomycin (1.45%), ethambutol (1.44%), rifampicin (1.23%) and isoniazid (0.98%). Various clinical characteristics of patients with CADR identified include Human Immunodeficiency Virus (HIV) infection (27.7%), polypharmacy (21.3%), elderly (19.1%), autoimmune disorders (6.4%), pre-existing renal impairment (4.3%), pre-existing liver disorders (4.3%). In conclusion, CADR is common and majority of cases occurred within two months after initiation of anti-TB treatment, particularly in HIV infected patients. Pyrazinamide is the commonest offending drug.
Fulltext The role of preoperative magnetic resonance imaging in internal derangement of the knee

Zairul-Nizam ZF, Hyzan MY, Gobinder S, Razak MA

Med J Malaysia, 2000 Dec;55(4):433-8.
PMID: 11221154

We attempted to compare the accuracy of our clinical examination and the usage of magnetic resonance imaging (MRI) in evaluating patients suspected of having internal derangement of the knee who were seen in our Orthopaedic clinic. This was done using the findings of arthroscopy as the 'gold standard'. The accuracy of MRI in detecting cruciate ligament tears was between 80-96% against 82-93% for clinical examination. MRI accuracy for meniscus injuries was 80-84% compared to 48-65% for clinical examination. We thus propose that MRI examination is an effective first-line investigation for patients with suspected internal knee derangement, especially menisci injuries; allowing arthroscopy to be reserved for patients in whom surgery is truly indicated.

Fulltext Efficient dielectrophoretic cell enrichment using a dielectrophoresis-well based system

Abdul Razak MA, Hoettges KF, Fatoyinbo HO, Labeed FH, Hughes MP

Biomicrofluidics, 2013;7(6):64110.
PMID: 24396544 DOI: 10.1063/1.4842395

Whilst laboratory-on-chip cell separation systems using dielectrophoresis are increasingly reported in the literature, many systems are afflicted by factors which impede "real world" performance, chief among these being cell loss (in dead spaces, attached to glass and tubing surfaces, or sedimentation from flow), and designs with large channel height-to-width ratios (large channel widths, small channel heights) that make the systems difficult to interface with other microfluidic systems. In this paper, we present a scalable structure based on 3D wells with approximately unity height-to-width ratios (based on tubes with electrodes on the sides), which is capable of enriching yeast cell populations whilst ensuring that up to 94.3% of cells processed through the device can be collected in tubes beyond the output.

Fulltext An Influenza A Vaccine Based on the Extracellular Domain of Matrix 2 Protein Protects BALB/C Mice Against H1N1 and H3N2

Ong HK, Yong CY, Tan WS, Yeap SK, Omar AR, Razak MA, et al.

Vaccines (Basel), 2019 08 19;7(3).
PMID: 31430965 DOI: 10.3390/vaccines7030091

Current seasonal influenza A virus (IAV) vaccines are strain-specific and require annual reconstitution to accommodate the viral mutations. Mismatches between the vaccines and circulating strains often lead to high morbidity. Hence, development of a universal influenza A vaccine targeting all IAV strains is urgently needed. In the present study, the protective efficacy and immune responses induced by the extracellular domain of Matrix 2 protein (M2e) displayed on the virus-like particles of Macrobrachium rosenbergii nodavirus (NvC-M2ex3) were investigated in BALB/c mice. NvC-M2ex3 was demonstrated to be highly immunogenic even in the absence of adjuvants. Higher anti-M2e antibody titers corresponded well with increased survival, reduced immunopathology, and morbidity of the infected BALB/c mice. The mice immunized with NvC-M2ex3 exhibited lower H1N1 and H3N2 virus replication in the respiratory tract and the vaccine activated the production of different antiviral cytokines when they were challenged with H1N1 and H3N2. Collectively, these results suggest that NvC-M2ex3 could be a potential universal influenza A vaccine.

PMID: 33562212 DOI: 10.3390/children8020119

Mental health problems are a major public health issue, particularly among children. They impair children's development, academic achievement, and ability to live a productive life. The present study aimed to determine the prevalence and factors associated with mental health problems among children aged 5 to 15 years old in Malaysia. Data from the National Health and Morbidity Survey (NHMS) 2015 were analyzed. A validated Strengths and Difficulties Questionnaire (SDQ) was used. The overall prevalence of mental health problems among children in Malaysia was 11.1%. Multiple logistic regression analysis revealed that for every year increment in age, mental health problems decreased by 5%. Further analysis found that children who had fathers with a non-formal education and worked in the private sector, had parents who were widowed or divorced, and had either parent with mental health problems were more likely to have mental health problems themselves. Children from the lower socioeconomic group and who had either parent with mental health problems had higher odds of having mental health problems in Malaysia.

Cancer Cell Int, 2010;10:42.
PMID: 20979664 DOI: 10.1186/1475-2867-10-42

The main morphological features of primitive cells, such as stem and progenitor cells, are that these cells consists only one nucleus. The main purpose of this study was to determine the differentiation capacities of stem and progenitor cells. This study was performed using mononucleated cells originated from murine peripheral blood and MC3T3-E1 cells. Three approaches were used to determine their differentiation capacities: 1) Biochemical assays, 2) Gene expression analysis, and 3) Morphological observations.

Bin Adnan MAA, Bin Kassim MSA, Bt Sahril N, Bin Abd Razak MA

Int J Environ Res Public Health, 2022 Dec 29;20(1).
PMID: 36612905 DOI: 10.3390/ijerph20010586

The COVID-19 pandemic has created anxiety among hospitalized SARS-CoV-2 patients. Therefore, this study aimed to determine the prevalence of anxiety and its associated factors among stable inpatient COVID-19 patients in Malaysia. Method: A cross-sectional study was conducted using a web-based online survey involving 401 patients from Malaysia’s leading COVID-19 hospitals from 15th April until 30th June 2020, who were chosen using quota sampling. The General Anxiety Disorders 7 items (GAD-7) scale, the Coping Orientation to Problems Experienced Inventory (Brief-COPE) and a socio-demographic profile questionnaire were used. Descriptive analysis and multiple logistic regression were performed using SPSS v23 to determine the prevalence of anxiety and its associated factors. Result: The results showed that the prevalence of anxiety was 7.0%. Multiple logistic regression analysis revealed that female gender (p < 0.05), a fear of infection (p < 0.05), a lack of information (p < 0.05), a maladaptive coping mechanism of behavioral disengagement (p < 0.001) and self-blame (p < 0.001) were significantly associated with anxiety. Meanwhile, adaptive coping mechanisms via instrumental support (p < 0.001) were a significant protective predictor of anxiety. Conclusions: COVID-19 infection has had a significant influence on the mental health of patients. Findings in our study provide baseline data on the prevalence of anxiety among stabilized COVID-19 inpatients in Malaysia. Despite the relatively low prevalence, the data have the potential to improve the present mental health monitoring system and the deployment of suitable treatments in dealing with similar circumstances.
Prevalence of inadequate HIV knowledge and its associated factors among the Malaysia general population: findings from the National Health and Morbidity Survey (NHMS) 2020

Adnan MAA, Sahril N, Abd Razak MA, Shamsuddin N, Hasim Hashim MH, Abdul Mutalip MH

J Health Popul Nutr, 2024 Nov 29;43(1):200.
PMID: 39614324 DOI: 10.1186/s41043-024-00689-y

BACKGROUND: Inadequate knowledge of human immunodeficiency virus (HIV) is underscored as a key factor contributing to the HIV epidemic. Nonetheless, current data on HIV knowledge in Malaysia are still scarce. Therefore, this study aimed to assess the prevalence of inadequate HIV knowledge and its associated factors among the general Malaysian population.
METHOD: The study utilized data from the National Health and Morbidity Survey (NHMS) 2020, a nationwide cross-sectional survey employing a two-stage stratified random sampling technique to ensure national representativeness. HIV knowledge was assessed using the UNGASS indicators questionnaire, which comprises five questions on HIV prevention and transmission. The data were collected using the computer assisted telephone interviewing (CATI) method. Respondents who did not correctly answer all five questions were considered to have inadequate knowledge about HIV. Descriptive analysis and complex sample logistic regression were performed using SPSS version 28.0.
RESULTS: The survey identified 5,561 eligible respondents, leading to the participation of 3,187 individuals in the second phase of the study, which resulted in a response rate of 57.3%. Our study revealed an overall prevalence of inadequate HIV knowledge at 77.4%, with adolescents aged 13-19 exhibiting the highest prevalence at 86.1%. Multiple logistic regression analysis indicated that respondents with no formal education (aOR 4.34, 95% CI: 0.65, 29.08) were over four times more likely to lack HIV knowledge. Additionally, respondents with only secondary education had an increased risk of 1.79 times. Individuals residing in rural areas were significantly more likely to have inadequate HIV-related knowledge. Furthermore, respondents who worked as unpaid workers, homemakers, or caregivers (aOR 1.71, 95% CI: 1.05, 2.82) showed a higher likelihood of lacking HIV knowledge.
CONCLUSION: Three out of four individuals in the general Malaysian population were found to lack sufficient knowledge about HIV. This underscores the need for targeted interventions in HIV education, particularly in rural areas and among populations with lower educational attainment. Additionally, digital platforms and youth-focused campaigns could be especially effective for reaching adolescents. Policymakers must prioritize inclusive, accessible HIV prevention strategies to address these gaps and reduce transmission rates.

Asia Pac J Public Health, 2019 Nov;31(8_suppl):18S-29S.
PMID: 31470742 DOI: 10.1177/1010539519870665

This study aimed to assess the prevalence and factors associated with bullying victimization from a nationwide school-based survey among 27 458 students aged 13 to 17 years. The overall prevalence of having been bullied in the past 30 days was 16.2%; this decreased with age. Multivariate logistic regression analysis revealed that factors most strongly associated with bullying victimization were exposure to physical attacks (adjusted odds ratio [aOR] = 2.46, 95% confidence interval [CI] = 2.17-2.79), illicit drug use (aOR = 2.44, 95% CI = 1.78-3.34), involvement in physical fights (aOR = 1.97, 95% CI = 1.74-2.23), being younger than 14 years (aOR =1.95, 95% CI = 1.59-2.38), and having ever attempted suicide (aOR = 1.83, 95% CI = 1.51-2.21). Other significantly associated factors include loneliness, truancy, making suicidal plans, and symptoms of depression, anxiety, and stress. Exposure to bullying victimization can result in negative lifelong sequelae and important associated factors should be considered in planning effective school-based anti-bullying interventions.

Limited evidence on the association of being bullied with depression among adolescents was found in Malaysia. This study aimed to determine the association of being bullied and depression among Malaysian school-going adolescents. Data from the National Health and Morbidity Survey 2017, a cross-sectional study conducted from March to May 2017, was analyzed using descriptive and multiple logistic regression analysis. A validated tool, the Depression, Anxiety, and Stress Scale-21 was used to categorize those with moderate or higher levels of depressive symptoms as having depression. A total of 27 399 school-going adolescents participated and 18.3% were found depressed. Adolescents of Indian ethnicity (adjusted odds ratio [aOR] = 2.02, P < .001), those with parents living apart (aOR = 1.41, P < .001), and those who were being bullied (aOR = 2.98, P < .001) were more likely to have depression. This study demonstrated the association between being bullied and having depression. Comprehensive preventive strategies should be implemented taking into consideration the findings from this study.

PMID: 33628485 DOI: 10.1155/2021/6657003

The trend of global prevalence for hypertension has been dramatically increasing for the past two decades in Southeast Asian countries. A systematic review aiming to assess the prevalence of hypertension and its risk factors among the urban population in Southeast Asian countries was conducted. We performed database searches of PubMed and Web of Science and performed meta-analysis to determine the pooled prevalence estimate. The overall pooled prevalence estimate of hypertension for Southeast Asian urban population was 33.82%. Among this, 33.98% of hypertension was reported in the community and 32.45% among adolescents in school. The common risk factors that we found were male, ethnicity, education and socioeconomic level, body mass index, waist circumference, smoking, and dyslipidaemia. The review indicates an urgent need for primary and secondary prevention activities. Therefore, a multisectoral and intersectoral approach and collaboration should be undertaken to improve the overall health outcomes of all populations in all Southeast Asian countries.

PMID: 30826688 DOI: 10.1016/j.puhe.2019.01.001

OBJECTIVES: This systematic review aims to provide updated and comprehensive evidence on the validity and feasibility of screening tools for mild cognitive impairment (MCI) and dementia among the elderly at primary healthcare level.
STUDY DESIGN: A review of articles was performed.
METHODS: A search strategy was used by using electronic bibliographic databases including PubMed, Embase and CENTRAL for published studies and reference list of published studies. The articles were exported to a bibliographic database for further screening process. Two reviewers worked independently to screen results and extract data from the included studies. Any discrepancies were resolved and confirmed by the consensus of all authors.
RESULTS: There were three screening approaches for detecting MCI and dementia - screening by a healthcare provider, screening by a self-administered questionnaire and caretaker informant screening. Montreal Cognitive Assessment (MoCA) was the most common and preferable tool for MCI screening (sensitivity [Sn]: 81-97%; specificity [Sp]: 60-86%), whereas Addenbrooke's Cognitive Examination (ACE) was the preferable tool for dementia screening (Sn: 79-100%; Sp: 86%).
CONCLUSION: This systematic review found that there are three screening approaches for detecting early dementia and MCI at primary health care. ACE and MoCA are recommended tools for screening of dementia and MCI, respectively.

Various factors contribute to suicidal attempt. This study aims to determine the relationship between suicidal attempt and its associated factors among school-going adolescents in Malaysia. Data from the National Health and Morbidity 2017 survey were analyzed. This survey was implemented as a nationwide school-based survey targeting adolescents 13 to 17 years old. Descriptive and multiple logistic regression analysis was done using SPSS version 20. A total of 27 399 adolescents participated in this survey. The prevalence of suicidal attempt was 6.9% (95% confidence interval = 6.2-7.7). Multivariate analysis found that the odds of suicidal attempt among adolescent with depression is 4.3 (adjusted odds ratio = 4.3; 95% confidence interval = 3.9-4.8). Other significant factors are young adolescent, non-Malay ethnicities especially Indian, adolescent with parents living apart, and those without peer support and parental connectedness. A holistic approach for the planning of preventative strategies and public health policies should be made according to these risk factors.

PMID: 33370858 DOI: 10.1111/ggi.14031

AIM: Dementia is the major cause of disability among older persons and leading physical and psychological sequelae for both the person living with dementia (PLwD) and their caregivers. The aim of this study was to determine the prevalence of dementia in Malaysia and identify the factors influencing quality of life (QoL) of caregivers of PLwD.
METHODS: A nationwide survey was conducted among individuals aged ≥60 years. Cognition was assessed with the Identification and Intervention for Dementia in Elderly Africans (IDEA) tool. QoL of older caregivers was assessed using the Control, Autonomy, Self-Realization and Pleasure (CASP-19) questionnaire.
RESULTS: The prevalence of dementia among older adults aged ≥60 years in Malaysia was found to be 8.5%. The prevalence was found to be higher among females, those with no formal education and those in rural areas in Malaysia. The mean QoL of family caregivers of PLwD was significantly lower than the caregivers of older adults without dementia were (P

Geriatr Gerontol Int, 2020 Dec;20 Suppl 2:21-25.
PMID: 33370850 DOI: 10.1111/ggi.14012

AIM: This study aimed to assess the relationship between functional limitations and depression among community-dwelling older adults in Malaysia.
METHODS: Data from a nation-wide community-based cross-sectional study were analyzed. This study was conducted using a two-stage stratified random sampling design. In total, 3772 older adults aged ≥60 years responded to the survey. Depression was identified using a validated Malay version of the Geriatric Depression Scale (M-GDS-14), with those scored ≥6 categorized as having depression. Functional limitations were assessed using both Barthel's Activities of Daily Living (ADL) and Lawton's Instrumental Activities of Daily Living (IADL). The relationship was determined by multivariate logistic regression, adjusted for other variables.
RESULTS: The prevalence of depression was 11.5% (95% confidence interval [CI] 9.4, 13.4). Multiple logistic regression analysis found that older adults with limitations in ADL were 2.6 times more likely of having depression (adjusted odds ratio [aOR] 2.58, 95% CI 2.01, 3.32), while those with limitations in IADL the risk of having depression was almost doubled (aOR 1.68, 95% CI: 1.32, 2.14). Other significant factors were incontinence (aOR 3.33, 95% CI: 2.33, 4.74), chronic medical illness (aOR 1.44, 95% CI: 1.15, 1.81), current smoker (aOR 4.19, 95% CI: 1.69, 10.39), poor social support (aOR 4.30, 95% CI: 2.98, 6.20), do not have partner, ethnic minorities and low individual monthly income.
CONCLUSIONS: Older adults with functional limitation in both basic ADL and complex IADL are independently at higher risk of having depression. Geriatr Gerontol Int 2020; 20: 21-25.
