Fulltext Suitability of Parkinson's patients for surgery in the north East coast of peninsular malaysia: a prospective analysis

Abdullah J, Abdullah MR

Malays J Med Sci, 2003 Jan;10(1):74-7.
PMID: 23365504 MyJurnal

There is no report in the English literature on the criteria for neuroablation or neuroaugmentation for the treatment of Parkinson's disease in a developing country like Malaysia. A prospective study of patients with Parkinson's disease from the north-eastern peninsular Malaysia was done to assess their suitability of surgery. Age, race, duration of illness and dementia were considered important factors towards the success of such surgical procedures. A mathematical model is suggested for future cases deemed to be suitable for neuroaugmentative or ablative surgery.
A pilot study on percent free prostate specific antigen as an additional tool in prostate cancer screening

Omar J, Jaafar Z, Abdullah MR

Malays J Med Sci, 2009 Jan;16(1):44-7.
PMID: 22589648 MyJurnal

A cross sectional pilot study was carried out to look into the usefulness of percent free prostate specific antigen (fPSA) in the diagnosis of prostatic cancer in HUSM patients. All patients who attended surgical clinic and admitted to surgical wards with signs and symptoms of prostate problems during the study period were taken as the study subjects. Total prostate specific antigen (tPSA) was estimated by immunoassay technique and those values of 4 ng/mL or more were proceeded for estimation of fPSA. Using the cut-off value of less than 25% fPSA for diagnosing patients with prostate cancer, our study showed that majority of the prostate cancer patients have a ratio of fPSA:tPSA more than 25% and a significantly higher level of total prostate specific antigen (P<0.005) when compared with patients with benign prostatic hyperplasia (BPH). Unexpectedly, the fPSA values were high in patients diagnosed as prostate cancer compared to BPH. Ratio of percent fPSA to tPSA was found not to be sensitive and specific, in diagnosing prostate cancer at the cut-off value of 25%. In conclusion, total PSA is a more useful biochemical test for diagnosing prostate cancer in our patients.

PMID: 16295557

Mild head injury (MHI) is a common presentation to many hospitals in both rural and urban settings in Southeast Asia, but it is not well studied. We studied 330 patients that presented to Hospital Universiti Sains Malaysia Emergency Department with possible MHI, with the intentions to identify prognostic factors that may improve the diagnosis of MHI in the emergency setting as well as to determine which patients would need follow-up. Patients' one-year outcomes were classified as discharged well (DW) for patients without post-traumatic signs and symptoms and discharged with long term follow-up (DFU) for patients with such signs and symptoms. Four patients died and 82 were DFU. An abnormal skull X ray was associated with mode of accident and type of transportation, older age, presence of vomiting, confusion, bleeding from ear, nose or throat, abnormal pupil size on the right side associated with orbital trauma, unequal pupillary reflexes, absence of loss of consciousness (LOC), a lower Glasgow Coma Scale (GCS) score, multiple clinical presentations, and DFU. An abnormal CT scan was associated with older age, multiple clinical presentation, skull X-ray findings, and DFU. A similar analysis on outcomes revealed that mode of accident, older age, vomiting, confusion, headache, bleeding from ear, nose and throat, neurological deficits, absence of LOC, pupil size, multiple presentation, abnormal skull X ray, CT scan of the brain, and a GCS of 13 was associated with DFU. In conclusion, all patients involved in motor vehicle accidents (MVAs), especially motorcycles, aged over 30 years of age, with multiple clinical presentations, including a lower GCS, and with abnormal radiological findings should have a longer follow-up due to persistent post-traumatic symptomatology.

Biomechanical and bioactivity concepts of polyetheretherketone composites for use in orthopedic implants-a review

Abdullah MR, Goharian A, Abdul Kadir MR, Wahit MU

J Biomed Mater Res A, 2015 Nov;103(11):3689-702.
PMID: 25856801 DOI: 10.1002/jbm.a.35480

The use of polyetheretherketone (PEEK) composites in the trauma plating system, total replacement implants, and tissue scaffolds has found great interest among researchers. In recent years (2008 afterward), this type of composites has been examined for suitability as substitute material over stainless steel, titanium alloys, ultra high molecular weight polyethylene, or even biodegradable materials in orthopedic implant applications. Biomechanical and bioactivity concepts were contemplated for the development of PEEK orthopedic implants and a few primary clinical studies reported the clinical outcomes of PEEK-based orthopedic implants. This study aims to review and discuss the recent concepts and contribute further concepts in terms of biomechanical and bioactivity challenges for the development of PEEK and PEEK composites in orthopedic implants.
Stroke patterns in Northeast Malaysia: a hospital-based prospective study

Jaya F, Win MN, Abdullah MR, Abdullah MR, Abdullah JM

Neuroepidemiology, 2002 Jan-Feb;21(1):28-35.
PMID: 11744823

All patients with a first-ever stroke admitted to the HUSM (Hospital Universiti Sains Malaysia) from 1997 to 1998 were included in this study. All risk factors were determined and analysed prospectively. There were 158 cases of stroke admitted during the study period. The majority of the patients were Malays (86.1%), with a male preponderance. The mean age (SD) of the patients with stroke was 59.3 (12.28) years. Hypertension was present in both cerebral infarct and intracerebral haemorrhage patients at almost the same rate (65.2 and 69.2%, respectively). The overall mortality was 37%, and most patients died in the 1st month after stroke (34%). We hope this study will highlight the problems associated with the presentation and management of stroke in Southeast Asia.

PMID: 12093129

Malaysia had the second highest crude accident rate in the world until 1998. Most children who were involved in these road traffic accidents required intensive neurosurgical care management. We report a prospective study on 36 paediatric neurotrauma patients in rural North East West Malaysia who underwent uniform intensive therapy and were subsequently followed up over a period of 2 years. The modified paediatric Glasgow Coma Scale with support of the revised Wechlser Intelligence Scale for children was used to test the outcome of these children over a period of two years. All patients were managed aggressively in our intensive care as well as our high dependency units. Our results indicate that improvement in outcome is seen after a six month period. Midline shift, duration of coma and duration of transport were found to be significant variables associated with bad outcome. Other variables i.e. age, sex, Glasgow Coma Scale on admission and on site, and lesions of the dominant lobe were not found to be associated with good outcome in these patients.

PMID: 15168228

Alteration of the tumor suppressor gene p53 is considered to be a critical step in the development of human cancer. Changes in this gene have been detected in a wide range of human tumours, including gliomas. In glioma, the presence of p53 gene alterations has been associated with worse prognosis.
Fulltext A machine learning approach of predicting high potential archers by means of physical fitness indicators

Muazu Musa R, P P Abdul Majeed A, Taha Z, Chang SW, Ab Nasir AF, Abdullah MR

PLoS One, 2019;14(1):e0209638.
PMID: 30605456 DOI: 10.1371/journal.pone.0209638

k-nearest neighbour (k-NN) has been shown to be an effective learning algorithm for classification and prediction. However, the application of k-NN for prediction and classification in specific sport is still in its infancy. The present study classified and predicted high and low potential archers from a set of physical fitness variables trained on a variation of k-NN algorithms and logistic regression. 50 youth archers with the mean age and standard deviation of (17.0 ± 0.56) years drawn from various archery programmes completed a one end archery shooting score test. Standard fitness measurements of the handgrip, vertical jump, standing broad jump, static balance, upper muscle strength and the core muscle strength were conducted. Multiple linear regression was utilised to ascertain the significant variables that affect the shooting score. It was demonstrated from the analysis that core muscle strength and vertical jump were statistically significant. Hierarchical agglomerative cluster analysis (HACA) was used to cluster the archers based on the significant variables identified. k-NN model variations, i.e., fine, medium, coarse, cosine, cubic and weighted functions as well as logistic regression, were trained based on the significant performance variables. The HACA clustered the archers into high potential archers (HPA) and low potential archers (LPA). The weighted k-NN outperformed all the tested models at itdemonstrated reasonably good classification on the evaluated indicators with an accuracy of 82.5 ± 4.75% for the prediction of the HPA and the LPA. Moreover, the performance of the classifiers was further investigated against fresh data, which also indicates the efficacy of the weighted k-NN model. These findings could be valuable to coaches and sports managers to recognise high potential archers from a combination of the selected few physical fitness performance indicators identified which would subsequently save cost, time and energy for a talent identification programme.
Fulltext Linear-Nonlinear Stiffness Responses of Carbon Fiber-Reinforced Polymer Composite Materials and Structures: A Numerical Study

The stiffness response or load-deformation/displacement behavior is the most important mechanical behavior that frequently being utilized for validation of the mathematical-physical models representing the mechanical behavior of solid objects in numerical method, compared to actual experimental data. This numerical study aims to investigate the linear-nonlinear stiffness behavior of carbon fiber-reinforced polymer (CFRP) composites at material and structural levels, and its dependency to the sets of individual/group elastic and damage model parameters. In this regard, a validated constitutive damage model, elastic-damage properties as reference data, and simulation process, that account for elastic, yielding, and damage evolution, are considered in the finite element model development process. The linear-nonlinear stiffness responses of four cases are examined, including a unidirectional CFRP composite laminate (material level) under tensile load, and also three multidirectional composite structures under flexural loads. The result indicated a direct dependency of the stiffness response at the material level to the elastic properties. However, the stiffness behavior of the composite structures depends both on the structural configuration, geometry, lay-ups as well as the mechanical properties of the CFRP composite. The value of maximum reaction force and displacement of the composite structures, as well as the nonlinear response of the structures are highly dependent not only to the mechanical properties, but also to the geometry and the configuration of the structures.

Pediatr Int, 2017 Aug;59(8):861-868.
PMID: 28510345 DOI: 10.1111/ped.13325

BACKGROUND: We examined the parental perception and accuracy of the Mandarin translation of the Parents' Evaluation of Developmental Status, a screening questionnaire for parent concerns about children's various developmental skills.
METHODS: The questionnaire was translated into Mandarin. Upon enrollment, caregivers completed the Mandarin PEDS and answered four questions about its acceptability and usefulness, and its ease of understanding and completion. The Mandarin PEDS was independently evaluated by a pediatrician and a community nurse, and classified as high risk (≥two predictive concerns), medium risk (one predictive concern), low risk (any non-predictive concerns) or no risk (if no concern) for developmental delays. The caregivers repeated Mandarin PEDS at a 2 week interval for test-retest reliability, while the children underwent testing for accuracy using a developmental assessment test.
RESULTS: The majority (≥85%) of the 73 caregivers perceived the Mandarin PEDS as acceptable and useful, as well as easy to understand and complete. Fifteen (20.5%) and 24 responses (33.9%) were classified as high and moderate risk, respectively. The test-retest and inter-rater reliabilities were excellent, with an intra-class correlation coefficient of 0.812 (95% CI: 0.701-0.881, P
Fulltext Wide area spray of bacterial larvicide, Bacillus thuringiensis israelensis strain AM65-52, integrated in the national vector control program impacts dengue transmission in an urban township in Sibu district, Sarawak, Malaysia

Several sites, Z-7L, Z-5 and Z-14, in Sibu district, Sarawak, Malaysia, experienced intense dengue transmission in 2014 that continued into 2015. A pilot study with Bacillus thuringiensis israelensis (Bti) to control Aedes aegypti (L.) and Ae. albopictus (Skuse) was evaluated in Z-7L, a densely populated site of 12 ha. Bti treatments were conducted weekly from epidemiology week (EW) 24/2015 for 4 weeks, followed by fortnight treatments for 2 months, in addition to the routine control activities. Bti was directly introduced into potable containers and the outdoor artificial and natural containers were treated via a wide area spray application method using a backpack mister. Aedes indices significantly reduced during the treatment and post treatment phases, compared to the control site, Z-5 (p<0.05). A 51 fold reduction in the incidence rate per 100,000 population (IR) was observed, with one case in 25 weeks (EW 29-52). In Z-5 and Z-14, control sites, a 6 fold reduction in the IR was observed from EW 29-52. However, almost every week there were dengue cases in Z-14 and until EW 44 in Z-5. In 2016, dengue cases resurfaced in Z-7L from EW 4. Intensive routine control activities were conducted, but the IR continued to escalate. The wide area Bti spray misting of the outdoor containers was then included from EW 27 on fortnight intervals. A 6 fold reduction in IR was observed in the Bti treatment phase (EW 32-52) with no successive weekly cases after EW 37. However, in the control sites, there were dengue cases throughout the year from EW 1-52, particularly in Z-14. We feel that the wide area Bti spray application method is an integral component in the control program, in conjunction with other control measures carried out, to suppress the vector population in outdoor cryptic containers and to interrupt the disease transmission.
Fulltext Supplementation of Eurycoma longifolia Jack Extract for 6 Weeks Does Not Affect Urinary Testosterone: Epitestosterone Ratio, Liver and Renal Functions in Male Recreational Athletes

PMID: 25013692

Background: Eurycoma longifolia Jack (ElJ) has been shown to elevate serum testosterone and increased muscle strength in humans. This study investigated the effects of Physta(®) a standardized water extract of ElJ (400 mg/day for 6 weeks) on testosterone: epitestosterone (T:E) ratio, liver and renal functions in male recreational athletes.

Methods: A total of 13 healthy male recreational athletes were recruited in this double blind, placebo-controlled, cross-over study. The participants were required to consume either 400 mg of ElJ or placebo daily for 6 weeks in the first supplementation regimen. Following a 3 week wash-out period, the participants were requested to consume the other supplement for another 6 weeks. Mid-stream urine samples and blood samples were collected prior to and after 6 weeks of supplementation with either ElJ or placebo. The urine samples were subsequently analyzed for T:E ratio while the blood samples were analyzed for liver and renal functions.

Results: T:E ratio was not significantly different following 6 weeks supplementation of either ElJ or placebo compared with their respective baseline values. Similarly, there were no significant changes in both the liver and renal functions tests following the supplementation of ElJ.

Conclusions: Supplementation of ElJ i.e. Physta(®) at a dosage of 400 mg/day for 6 weeks did not affect the urinary T:E ratio and hence will not breach any doping policies of the International Olympic Committee for administration of exogenous testosterone or its precursor. In addition, the supplementation of ElJ at this dosage and duration was safe as it did adversely affect the liver and renal functions.

Keywords: Doping; Eurycoma longifolia Jack; liver function; renal function; testosterone: epitestosterone ratio.

The popularity of modern tennis has contributed to the increasing number of participants at both recreational and competitive levels. The influx of numerous tennis participants has resulted in a wave of injury occurrences of different types and magnitudes across both male and female players. Since tennis injury harms both players' economic and career development, a better understanding of its epidemiology could potentially curtail its prevalence and occurrences. We used online-based tennis-related injury reports to study the prevalence, location types, and injury intensities in both male and female tennis players for the past five years. It is demonstrated from the chi-square analysis that injury occurrences are significantly associated with a specific gender (χ2(18) = 50.773; p = 0.001), with male players having a higher risk of injury manifestation (68.10%) as compared with female players (31.90%). Nonetheless, knee, hip, ankle, and shoulder injuries are highly prevalent in both male and female players. Moreover, the injury intensities are distributed across gender (χ2(2) = 0.398; p = 0.820), with major injuries being dominant, followed by minor injuries, whilst a few cases of career-threatening injuries were also reported. It was similarly observed that male players recorded a higher degree of both major, minor, and career-threatening injuries than female players. In addition, male players sustained more elbow, hip, knee, shoulder, and thigh injuries than female players. Whereas, female players mostly suffered from Achilles and back injuries, ankle and hamstring injuries affected both genders. The usage of online newspaper reports is pivotal in characterizing the epidemiology of tennis-related injuries based on locations and gender to better understand the pattern and localization of injuries, which could be used to address the problem of modern tennis-related injuries.
Transfusion practice blind spot in para-Bombay: A case report

Abdullah MR, Faizli AA, Noordin SS, Lee CJ, Ahmad NH

Transfus Apher Sci, 2021 Jun;60(3):103076.

H-deficient phenotype individuals with absent or weak anti-H activity may remain undetected on standard routine blood grouping. We report a case of a 59-year-old-man presented with symptomatic anaemia secondary to upper gastrointestinal bleed with haemoglobin level of 68 g/L who required two units of packed red blood cells. He was previously grouped as O Rh D positive and had a history of uneventful multiple blood transfusions. His latest pre-transfusion investigations showed ABO discrepancy between forward and reverse blood grouping, pan-agglutination in both antibody screening and identification with negative direct Coombs test and autocontrol. Further testing including anti-H lectin test and saliva secretor study confirmed that the patient blood group was para-Bombay B RhD positive. This case highlights that the para-Bombay phenotype can be mistakenly labelled as "O" if further investigations are not performed.

Support Vector Machine (SVM) has been shown to be an effective learning algorithm for classification and prediction. However, the application of SVM for prediction and classification in specific sport has rarely been used to quantify/discriminate low and high-performance athletes. The present study classified and predicted high and low-potential archers from a set of fitness and motor ability variables trained on different SVMs kernel algorithms. 50 youth archers with the mean age and standard deviation of 17.0 ± 0.6 years drawn from various archery programmes completed a six arrows shooting score test. Standard fitness and ability measurements namely hand grip, vertical jump, standing broad jump, static balance, upper muscle strength and the core muscle strength were also recorded. Hierarchical agglomerative cluster analysis (HACA) was used to cluster the archers based on the performance variables tested. SVM models with linear, quadratic, cubic, fine RBF, medium RBF, as well as the coarse RBF kernel functions, were trained based on the measured performance variables. The HACA clustered the archers into high-potential archers (HPA) and low-potential archers (LPA), respectively. The linear, quadratic, cubic, as well as the medium RBF kernel functions models, demonstrated reasonably excellent classification accuracy of 97.5% and 2.5% error rate for the prediction of the HPA and the LPA. The findings of this investigation can be valuable to coaches and sports managers to recognise high potential athletes from a combination of the selected few measured fitness and motor ability performance variables examined which would consequently save cost, time and effort during talent identification programme.

The non-complexity of tennis, coupled with its health benefits, renders it appealing and encourages varying competitions at different levels of age, gender, and expertise. However, the rapid increase in the participation rates witnesses a surge in injury occurrences, prompting the need for in-depth analysis to facilitate immediate intervention. We employed a media content analysis technique in which tennis-associated articles published in the last 5 years were examined. A total of 207 news reports were gathered and screened for analysis. Subsequently, 71 articles were excluded from the study due to content duplications or summary updates of existing news articles, while 23 news articles were also excluded from the study due to inappropriateness. Finally, 113 news reports directly related to injury in tennis were coded and analyzed. We examined various types of injuries reported from the screened articles with respect to their status (fresh, recurrent, and recovery) across expertise levels i.e., elite, or amateur. Similarly, the incidence of injury occurrences based on the types of tournaments the players engage in was also investigated. A chi-square analysis was employed to achieve the objectives of the study. Occurrences of tennis-associated injuries are disseminated across expertise levels [ χ ( 18 ) 2 = 16.542; p = 0.555], with knee, hip, elbow, and shoulder injuries being highly prevalent in both elite and amateur players. Nevertheless, it was noted that elite players suffered a staggering 72.60% of injury-related problems, while amateur players sustained 27.40% of injuries. Moreover, the status of injury spreads based on types of tournaments [ χ ( 4 ) 2 = 3.374; p = 0.497], with higher occurrences of fresh and recurrent injuries, while low recovery rates were observed. The findings further demonstrated that injuries are sustained regardless of tournament types [ χ ( 36 ) 2 = 39.393; p = 0.321]. However, most of the injuries occurred at international tournaments (85%). Whereas, only 5.30% of the injuries occurred at national/regional tournaments while 9.70% were unidentified. It could be deduced from the findings of this investigation that elite players are more prone to injuries compared with amateur players. Furthermore, the most common tennis-related injuries affect the lower, trunk, and upper regions of the body, respectively. A large number of the reported tennis injuries are fresh and recurrent, with a few recoveries. The international tennis tournaments are highly attributed to injury occurrences as opposed to the national/regional tournaments. The application of the media-based data mining technique is non-trivial in projecting injury-related problems that could be used to facilitate the development of an injury index peculiar to the tennis sport for prompt intervention.
Fulltext Serum Procalcitonin (PCT) - Is there a Role as an Early Biomarker in Infected Diabetic Foot Ulcer (IDFU) Patients?

Malays Orthop J, 2023 Jul;17(2):62-69.
PMID: 37583519 DOI: 10.5704/MOJ.2307.010

INTRODUCTION: Infected diabetic foot ulcers may lead to serious complications if not recognised in the early stage. Diagnosis of infection is particularly challenging at that stage; thus, a sensitive inflammatory biomarker may be helpful. We aimed to evaluate the role of procalcitonin (PCT) as an early biomarker for infected diabetic foot ulcers (IDFU).
MATERIALS AND METHOD: This cross-sectional study was conducted at Klinik Rawatan Keluarga (KRK), Orthopedic clinic and wards in Hospital Universiti Sains Malaysia (USM) from May 2020 to December 2020. A total of 264 participants were recruited and divided into three groups: 50 diabetic patients with no ulcers (control), 107 patients with non-infected diabetic foot ulcers (NIDFU), and 107 patients with infected diabetic foot ulcers (IDFU). The level of PCT was taken for all patients. Total white count (TWC) and C-reactive protein (CRP) were taken only for IDFU patients. Diagnosis of infection was based on the Infectious Disease Society of America-International Working Group of Diabetic Foot (IDSA-IMWGDF), and the severity of infection was graded according to the Wagner Classification.
RESULTS: The level of PCT was higher in IDFU than in NIDFU and diabetic patient, with a median (IQR) of 0.355 (0.63) ng/mL, 0.077 (0.15) ng/mL and 0.028 (0.02) ng/mL, respectively. PCT and CRP showed moderate positive correlations in IDFU patients (p<0.001). The sensitivity and specificity were 63.6% and 83.2%, respectively, at the best cut-off at 0.25 ng/mL.
CONCLUSION: PCT is a valuable biomarker for the diagnosis of infection; however, it adds little value in the early diagnosis of IDFU in view of its low sensitivity.
