  1. Predicting the risk of exacerbation in patients with chronic obstructive pulmonary disease using home telehealth measurement data
    Mohktar MS, Redmond SJ, Antoniades NC, Rochford PD, Pretto JJ, Basilakis J, et al.
    Artif Intell Med, 2015 Jan;63(1):51-9.
    PMID: 25704112 DOI: 10.1016/j.artmed.2014.12.003
    BACKGROUND: The use of telehealth technologies to remotely monitor patients suffering chronic diseases may enable preemptive treatment of worsening health conditions before a significant deterioration in the subject's health status occurs, requiring hospital admission.
    OBJECTIVE: The objective of this study was to develop and validate a classification algorithm for the early identification of patients, with a background of chronic obstructive pulmonary disease (COPD), who appear to be at high risk of an imminent exacerbation event. The algorithm attempts to predict the patient's condition one day in advance, based on a comparison of their current physiological measurements against the distribution of their measurements over the previous month.
    METHOD: The proposed algorithm, which uses a classification and regression tree (CART), has been validated using telehealth measurement data recorded from patients with moderate/severe COPD living at home. The data were collected from February 2007 to January 2008, using a telehealth home monitoring unit.
    RESULTS: The CART algorithm can classify home telehealth measurement data into either a 'low risk' or 'high risk' category with 71.8% accuracy, 80.4% specificity and 61.1% sensitivity. The algorithm was able to detect a 'high risk' condition one day prior to patients actually being observed as having a worsening in their COPD condition, as defined by symptom and medication records.
    CONCLUSION: The CART analyses have shown that features extracted from three types of physiological measurements; forced expiratory volume in 1s (FEV1), arterial oxygen saturation (SPO2) and weight have the most predictive power in stratifying the patients condition. This CART algorithm for early detection could trigger the initiation of timely treatment, thereby potentially reducing exacerbation severity and recovery time and improving the patient's health. This study highlights the potential usefulness of automated analysis of home telehealth data in the early detection of exacerbation events among COPD patients.

  2. Fulltext Expression of P16 in high-risk human papillomavirus related lesions of the uterine cervix in a government hospital, Malaysia
    Krishnappa P, Mohamad IB, Lin YJ, Barua A
    Diagn Pathol, 2014;9:202.
    PMID: 25361681 DOI: 10.1186/s13000-014-0202-z
    Cervical cancer is one of the most common cancers affecting women worldwide. It is well established that human papilloma virus (HPV) infection is the prime risk factor in the development of cervical cancer. The current screening and diagnostic tests have limitations in identifying the range of lesions caused by HPV. The current study aims to evaluate the diagnostic value of p16 immunohistochemical (IHC) investigation in high-risk human papillomavirus (HR-HPV) related lesions of the uterine cervix in Hospital Tuanku Jaafar, Seremban, Malaysia.

    Jefferies JM, Mohd Yusof MY, Devi Sekaran S, Clarke SC
    PLoS One, 2014;9(6):e97912.
    PMID: 24941079 DOI: 10.1371/journal.pone.0097912
    Although Streptococcus pneumoniae is a leading cause of childhood disease in South East Asia, little has previously been reported regarding the epidemiology of invasive pneumococcal disease in Malaysia and very few studies have explored pneumococcal epidemiology using multilocus sequence typing (MLST). Here we describe serotype, multilocus sequence type (ST), and penicillin susceptibility of thirty pneumococcal invasive disease isolates received by the University of Malaya Medical Centre between February 2000 and January 2007 and relate this to the serotypes included in current pneumococcal conjugate vaccines. A high level of diversity was observed; fourteen serotypes and 26 sequence types (ST), (11 of which were not previously described) were detected from 30 isolates. Penicillin non-susceptible pneumococci accounted for 33% of isolates. The extent of molecular heterogeneity within carried and disease-causing Malaysian pneumococci remains unknown. Larger surveillance and epidemiological studies are now required in this region to provide robust evidence on which to base future vaccine policy.

  5. Fulltext Changes in trends and pattern of strong opioid prescribing in primary care
    Zin CS, Chen LC, Knaggs RD
    Eur J Pain, 2014 Oct;18(9):1343-51.
    PMID: 24756859 DOI: 10.1002/j.1532-2149.2014.496.x
    BACKGROUND: This study evaluated the prescribing trends of four commonly prescribed strong opioids in primary care and explored utilization in non-cancer and cancer users.
    METHODS: This cross-sectional study was conducted from 2000 to 2010 using the UK Clinical Practice Research Datalink. Prescriptions of buprenorphine, fentanyl, morphine and oxycodone issued to adult patients were included in this study. Opioid prescriptions issued after patients had cancer medical codes were defined as cancer-related use; otherwise, they were considered non-cancer use. Annual number of prescriptions and patients, defined daily dose (DDD/1000 inhabitants/day) and oral morphine equivalent (OMEQ) dose were measured in repeat cross-sectional estimates.
    RESULTS: In total, there were 2,672,022 prescriptions (87.8% for non-cancer) of strong opioids for 178,692 users (59.9% female, 83.9% non-cancer, mean age 67.1 ± 17.0 years) during the study period. The mean annual (DDD/1000 inhabitants/day) was higher in the non-cancer group than in the cancer group for all four opioids; morphine (0.73 ± 0.28 vs. 0.12 ± 0.04), fentanyl (0.46 ± 0.29 vs. 0.06 ± 0.24), oxycodone (0.24 ± 0.19 vs. 0.038 ± 0.028) and buprenorphine (0.23 ± 0.15 vs. 0.008 ± 0.006). The highest proportion of patients were prescribed low opioid doses (OMEQ ≤ 50 mg/day) in both non-cancer (50.3%) and cancer (39.9%) groups, followed by the dose ranks of 51-100 mg/day (26.2% vs. 28.7%), 101-200 mg/day (15.1% vs. 19.2%) and >200 mg/day (8.25% vs. 12.1%).
    CONCLUSIONS: There has been a huge increase in strong opioid prescribing in the United Kingdom, with the majority of prescriptions for non-cancer pain. Morphine was the most frequently prescribed, but the utilization of oxycodone, buprenorphine and fentanyl increased markedly over time.

  6. Purification of human adipose-derived stem cells from fat tissues using PLGA/silk screen hybrid membranes
    Chen DC, Chen LY, Ling QD, Wu MH, Wang CT, Suresh Kumar S, et al.
    Biomaterials, 2014 May;35(14):4278-87.
    PMID: 24565521 DOI: 10.1016/j.biomaterials.2014.02.004
    The purification of human adipose-derived stem cells (hADSCs) from human adipose tissue cells (stromal vascular fraction) was investigated using membrane filtration through poly(lactide-co-glycolic acid)/silk screen hybrid membranes. Membrane filtration methods are attractive in regenerative medicine because they reduce the time required to purify hADSCs (i.e., less than 30 min) compared with conventional culture methods, which require 5-12 days. hADSCs expressing the mesenchymal stem cell markers CD44, CD73, and CD90 were concentrated in the permeation solution from the hybrid membranes. Expression of the surface markers CD44, CD73, and CD99 on the cells in the permeation solution from the hybrid membranes, which were obtained using 18 mL of feed solution containing 50 × 10⁴ cells, was statistically significantly higher than that of the primary adipose tissue cells, indicating that the hADSCs can be purified in the permeation solution by the membrane filtration method. Cells expressing the stem cell-associated marker CD34 could be successfully isolated in the permeation solution, whereas CD34⁺ cells could not be purified by the conventional culture method. The hADSCs in the permeation solution demonstrated a superior capacity for osteogenic differentiation based on their alkali phosphatase activity, their osterix gene expression, and the results of mineralization analysis by Alizarin Red S and von Kossa staining compared with the cells from the suspension of human adipose tissue. These results suggest that the hADSCs capable of osteogenic differentiation preferentially permeate through the hybrid membranes.

  7. Chronic kidney disease, cardiovascular disease and mortality: A prospective cohort study in a multi-ethnic Asian population
    Lim CC, Teo BW, Ong PG, Cheung CY, Lim SC, Chow KY, et al.
    Eur J Prev Cardiol, 2015 Aug;22(8):1018-26.
    PMID: 24857889 DOI: 10.1177/2047487314536873
    BACKGROUND: Few studies have examined the impact of chronic kidney disease (CKD) on adverse cardiovascular outcomes and deaths in Asian populations. We evaluated the associations of CKD with cardiovascular disease (CVD) and all-cause mortality in a multi-ethnic Asian population.
    DESIGN: Prospective cohort study of 7098 individuals who participated in two independent population-based studies involving Malay adults (n = 3148) and a multi-ethnic cohort of Chinese, Malay and Indian adults (n = 3950).
    METHODS: CKD was assessed from CKD-EPI estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR). Incident CVD (myocardial infarction, stroke and CVD mortality) and all-cause mortality were identified by linkage with national disease/death registries.
    RESULTS: Over a median follow-up of 4.3 years, 4.6% developed CVD and 6.1% died. Risks of both CVD and all-cause mortality increased with decreasing eGFR and increasing albuminuria (all p-trend <0.05). Adjusted hazard ratios (HR (95% confidence interval)) of CVD and all-cause mortality were: 1.54 (1.05-2.27) and 2.21 (1.67-2.92) comparing eGFR <45 vs ≥60; 2.81 (1.49-5.29) and 2.34 (1.28-4.28) comparing UACR ≥300 vs <30. The association between eGFR <60 and all-cause mortality was stronger among those with diabetes (p-interaction = 0.02). PAR of incident CVD was greater among those with UACR ≥300 (12.9%) and that of all-cause mortality greater among those with eGFR <45 (16.5%).
    CONCLUSIONS: In multi-ethnic Asian adults, lower eGFR and higher albuminuria were independently associated with incident CVD and all-cause mortality. These findings extend previously reported similar associations in Western populations to Asians and emphasize the need for early detection of CKD and intervention to prevent adverse outcomes.

    Asian Pac J Cancer Prev, 2014;15(7):3287-91.
    PMID: 24815484
    BACKGROUND: The interesting preponderance of Chinese with colorectal carcinoma (CRC) amongst the three major ethnic groups in Malaysia prompted a study to determine DNA mismatch repair (MMR) status in our CRC and attempt correlation with patient age, gender and ethnicity as well as location, grade, histological type and stage of tumour. Histologically re-confirmed CRC, diagnosed between 1st January 2005 and 31st December 2007 at the Department of Pathology, University of Malaya Medical Centre, were immunohistochemically stained with monoclonal antibodies to MMR proteins, MLH1, MSH2, MSH6 and PMS2 on the Ventana Benchmark XT autostainer. Of the 142 CRC cases entered into the study, there were 82 males and 60 females (M:F=1.4:1). Ethnically, 81 (57.0%) were Chinese, 32 (22.5%) Malays and 29 (20.4%) Indians. The patient ages ranged between 15-87 years (mean=62.4 years) with 21 cases <50-years and 121 ≥50-years of age. 14 (9.9%) CRC showed deficient MMR (dMMR). Concurrent loss of MLH1 and PMS2 occurred in 10, MSH2 and MSH6 in 2 with isolated loss of MSH6 in 1 and PMS2 in 1. dMMR was noted less frequently amongst the Chinese (6.2%) in comparison with their combined Malay and Indian counterparts (14.8%), and was associated with right sided and poorly differentiated tumours (p<0.05). 3 of the 5 (60.0%) dMMR CRC cases amongst the Chinese and 1 of 9 cases (11.1%) amongst the combined Malay and Indian group were <50-years of age. No significant association of dMMR was noted with patient age and gender, tumour stage or mucinous type.

    Gan GG, Subramaniam R, Bee PC, Chin EF, Abdul-Halim H, Tai MC
    Asian Pac J Cancer Prev, 2014;15(4):1703-6.
    PMID: 24641394
    BACKGROUND: The current standard treatment for patients with newly diagnosed diffuse large B cell lymphoma (DLBCL) is rituximab combined with cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP). A significant number of patients were not treated with recommended dose of rituximab due to limited financial resources in Malaysia. This study evaluates the efficacy of R-CHOP like chemotherapy in Malaysian patients with DLBCL.

    MATERIALS AND METHODS: The study comprised a retrospective analysis of patients with DLBCL treated at a single centre. The outcome was compared with patients who were treated with R-CHOP like and CHOP like chemotherapy. Patients who were treated with lower dose of rituximab was subanalysed for outcome.

    RESULTS: A total of 86 patients who had CHOP-like chemotherapy were included. Only 39 (45%) patients had rituximab and only 12 (29%) patients had the recommended dose. The overall response (OR) and complete response (CR) rates were 88% and 81% respectively. There was no significant difference in OR and CR in patients who had rituximab and those without rituxmab. Those with International Prognostic Index (IPI) score of ≤ 2 had significant higher CR rate, progression free survival (PFS) and overall survival (p<0.001).

    CONCLUSIONS: The lack of significant improvement in CR and DFS in our patients may be due to an inadequate dose of rituximab.

  11. Are reports of cognitive testing among older electroconvulsive therapy recipients clinically valid?
    Plakiotis C, Chin LF, O'Connor DW
    J ECT, 2014 Mar;30(1):26-9.
    PMID: 24487645 DOI: 10.1097/YCT.0000000000000082
    Electroconvulsive therapy (ECT) administration rises in frequency with age, with older depressed adults often showing clinical features predictive of good response. Recent reviews suggest that older people experience few if any long-term cognitive adverse effects after contemporary ECT, despite their increased vulnerability to these. However, the broader clinical validity of research findings is not assured as most studies of ECT-related cognitive effects do not discuss cognitive test nonparticipants. This study examines whether cognitive test participants and nonparticipants are comparable.

  12. Clinical prognostic factors and survival outcome in renal cell carcinoma patients--a malaysian single centre perspective
    Yap NY, Ng KL, Ong TA, Pailoor J, Gobe GC, Ooi CC, et al.
    Asian Pac J Cancer Prev, 2013;14(12):7497-500.
    PMID: 24460324
    BACKGROUND: This study concerns clinical characteristics and survival of renal cell carcinoma (RCC) patients in University Malaya Medical Centre (UMMC), as well as the prognostic significance of presenting symptoms.

    MATERIALS AND METHODS: The clinical characteristics, presenting symptoms and survival of RCC patients (n=151) treated at UMMC from 2003-2012 were analysed. Symptoms evaluated were macrohaematuria, flank pain, palpable abdominal mass, fever, lethargy, loss of weight, anaemia, elevated ALP, hypoalbuminemia and thrombocytosis. Univariate and multivariate Cox regression analyses were performed to determine the prognostic significance of these presenting symptoms. Kaplan Meier and log rank tests were employed for survival analysis.

    RESULTS: The 2002 TNM staging was a prognostic factor (p<0.001) but Fuhrman grading was not significantly correlated with survival (p=0.088). At presentation, 76.8% of the patients were symptomatic. Generally, symptomatic tumours had a worse survival prognosis compared to asymptomatic cases (p=0.009; HR 4.74). All symptoms significantly affect disease specific survival except frank haematuria and loin pain on univariate Cox regression analysis. On multivariate analysis adjusted for stage, only clinically palpable abdominal mass remained statistically significant (p=0.027). The mean tumour size of palpable abdominal masses, 9.5±4.3cm, was larger than non palpable masses, 5.3±2.7cm (p<0.001).

    CONCLUSIONS: This is the first report which includes survival information of RCC patients from Malaysia. Here the TNM stage and a palpable abdominal mass were independent predictors for survival. Further investigations using a multicentre cohort to analyse mortality and survival rates may aid in improving management of these patients.

  13. Fulltext Poor glycemic control in younger women attending Malaysian public primary care clinics: findings from adults diabetes control and management registry
    Cheong AT, Lee PY, Sazlina SG, Mohamad Adam B, Chew BH, Mastura I, et al.
    BMC Fam Pract, 2013;14:188.
    PMID: 24325794 DOI: 10.1186/1471-2296-14-188
    BACKGROUND: Women of reproductive age are a group of particular concern as diabetes may affect their pregnancy outcome as well as long-term morbidity and mortality. This study aimed to compare the clinical profiles and glycemic control of reproductive and non-reproductive age women with type 2 diabetes (T2D) in primary care settings, and to determine the associated factors of poor glycemic control in the reproductive age group women.
    METHODS: This was a cross-sectional study using cases reported by public primary care clinics to the Adult Diabetes Control and Management registry from 1st January to 31st December 2009. All Malaysian women aged 18 years old and above and diagnosed with T2D for at least 1 year were included in the analysis. The target for glycemic control (HbA1c < 6.5%) is in accordance to the recommended national guidelines. Both univariate and multivariate approaches of logistic regression were applied to determine whether reproductive age women have an association with poor glycemic control.
    RESULTS: Data from a total of 30,427 women were analyzed and 21.8% (6,622) were of reproductive age. There were 12.5% of reproductive age women and 18.0% of non-reproductive age women that achieved glycemic control. Reproductive age group women were associated with poorer glycemic control (OR = 1.5, 95% CI = 1.2-1.8). The risk factors associated with poor glycemic control in the reproductive age women were being of Malay and Indian race, longer duration of diabetes, patients on anti-diabetic agents, and those who had not achieved the target total cholesterol and triglycerides.
    CONCLUSION: Women with T2D have poor glycemic control, but being of reproductive age was associated with even poorer control. Health care providers need to pay more attention to this group of patients especially for those with risk factors. More aggressive therapeutic strategies to improve their cardiometabolic control and pregnancy outcome are warranted.

  14. Fulltext Methods and matrices: approaches to identifying miRNAs for nasopharyngeal carcinoma
    Plieskatt JL, Rinaldi G, Feng Y, Levine PH, Easley S, Martinez E, et al.
    J Transl Med, 2014;12:3.
    PMID: 24393330 DOI: 10.1186/1479-5876-12-3
    Nasopharyngeal carcinoma (NPC) is a solid tumor of the head and neck. Multimodal therapy is highly effective when NPC is detected early. However, due to the location of the tumor and the absence of clinical signs, early detection is difficult, making a biomarker for the early detection of NPC a priority. The dysregulation of small non-coding RNAs (miRNAs) during carcinogenesis is the focus of much current biomarker research. Herein, we examine several miRNA discovery methods using two sample matrices to identify circulating miRNAs (c-miRNAs) associated with NPC.

    The lymphatic filarial parasite Brugia timori occurs only in eastern Indonesia where it causes high morbidity. The absence of an animal reservoir, the inefficient transmission by Anopheles mosquitoes and the high sensitivity to DEC/albendazole treatment make this species a prime candidate for elimination by mass drug administration (MDA).

  16. Clinical profile, morbidity, and outcome of adult-onset generalized pustular psoriasis: analysis of 102 cases seen in a tertiary hospital in Johor, Malaysia
    Choon SE, Lai NM, Mohammad NA, Nanu NM, Tey KE, Chew SF
    Int J Dermatol, 2014 Jun;53(6):676-84.
    PMID: 23967807 DOI: 10.1111/ijd.12070
    BACKGROUND: Generalized pustular psoriasis (GPP) is a severe but rare variant of psoriasis. Our objective is to review the clinical profile, comorbidities, and outcome of patients with GPP.
    MATERIALS AND METHODS: A retrospective note review of all patients with adult-onset GPP.
    RESULTS: A total of 102 patients with adult-onset GPP were diagnosed between 1989 and November 2011, with a female to male ratio of 2 : 1. The mean age at onset of GPP was 40.9 years (range: 21-81 years). Acute GPP was the most common variant seen (95 cases), followed by four localized variants of GPP and three with annular pustular psoriasis. Fever and painful skin were present in 89% of patients, arthritis in 34.7%, and leukocytosis in 78.4%. Common triggers were systemic steroids (45 cases), pregnancy (17 cases), and upper respiratory tract infections (16 cases). A positive family history of psoriasis and GPP was present in 29% and 11%, respectively. Comorbidities included obesity (42.9%), hypertension (25.7%), hyperlipidemia (25.7%), and diabetes mellitus (23.7%). The mean duration of admission and pustular flare for acute GPP was 10.3 days (range: 3-44 days) and 16 days (range: 7-60 days), respectively. Fifty-four patients responded to systemic retinoid, 21 to methotrexate, eight to cyclosporine, and one to adalimumab, but recurrences were common.
    CONCLUSIONS: Our study confirms the poor response of GPP to currently available anti-psoriatic agents, with frequent flare-ups. There is a need for a more effective targeted therapy for this condition.

    PMID: 23523861 DOI: 10.1016/j.exppara.2013.03.001
    Giardia duodenalis is an important intestinal protozoan in Yemen with infection rates ranging from 18% to 27%. To date, there has been no genotyping study to provide a better understanding of the transmission dynamic. This study was conducted to genotype and subtype G. duodenalis in Yemen. Stool samples were collected from 503 Yemeni outpatients between 1 and 80 years old, including 219 males and 284 females. Giardia cysts were detected via microscopy after the formal-ether concentration. Genotyping of Giardia was carried out using PCR and sequence analysis of the 16s rRNA and b-giardin genes. Of the 89 microscopy-positive Giardia samples, 65 were successfully sequenced, of which 66% (43 of 65) were identified as G. duodenalis assemblage A and 34% (22 of 65) as assemblage B. Further subtyping analysis based on b-giardin gene identified the presence of subtypes A2 and A3, which belong to the anthroponotic sub-assemblage AII. Data of the study suggest that anthroponotic transmission played a potential role in the transmission of giardiasis in the community. However, further genotyping and subtyping studies of specimens from humans and animals living in the same households are needed for a more definitive understanding of giardiasis transmission in Yemen.

  19. Efficacy and safety of maintenance erlotinib in Asian patients with advanced non-small-cell lung cancer: a subanalysis of the phase III, randomized SATURN study
    Wu YL, Kim JH, Park K, Zaatar A, Klingelschmitt G, Ng C
    Lung Cancer, 2012 Aug;77(2):339-45.
    PMID: 22494567 DOI: 10.1016/j.lungcan.2012.03.012
    Maintenance therapy, commenced immediately after the completion of first-line chemotherapy, is a promising strategy for improving treatment outcomes in patients with non-small-cell lung cancer (NSCLC). The global phase III SequentiAl Tarceva in UnResectable NSCLC (SATURN) study evaluated the efficacy and safety of the epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitor erlotinib as maintenance treatment in NSCLC patients without progression after first-line chemotherapy. We report a retrospective subanalysis of Asian patients enrolled in SATURN. Patients with advanced NSCLC with no evidence of progression after four cycles of chemotherapy were randomized to receive erlotinib 150 mg/day or placebo, until progressive disease or limiting toxicity. The co-primary endpoints of SATURN were progression-free survival (PFS) in all patients and in those with positive EGFR immunohistochemistry (IHC) status. Secondary endpoints included overall survival (OS), disease control rate, safety, quality of life (QoL) and biomarker analyses. In total, 126 patients from East and South-East Asian centers were randomized (14% of the intent-to-treat population): 88 from Korea, 28 from China and 10 from Malaysia; one patient was excluded from this analysis due to Indian ethnicity. PFS was significantly prolonged in the erlotinib treatment arm, both overall (hazard ratio [HR]: 0.57; p=0.0067) and in patients with EGFR IHC-positive disease (HR=0.50; p=0.0057). There was a trend towards an increase in OS, which reached statistical significance in the EGFR IHC-positive subgroup (p=0.0233). The overall response rate was significantly higher with erlotinib compared with placebo (24% versus 5%; p=0.0025). Erlotinib was generally well tolerated and had no negative impact on QoL in this subpopulation. The most common treatment-related adverse events were rash, diarrhea and pruritus. Erlotinib was effective and well tolerated in Asian patients, producing benefits consistent with those observed in the overall SATURN population. Maintenance treatment with erlotinib appears to be a useful option for the management of Asian patients with advanced NSCLC without progression after first-line chemotherapy.

    Numerous studies with compelling evidence had shown a clear relationship between dyslipidaemia and cardiovascular (CV) events in patients with diabetes mellitus. This was an observational study based on secondary data from the online registry database Adult Diabetes Control and Management (ADCM) looking into the determinants of uncontrolled dyslipidaemia in type 2 diabetes mellitus patients. Independent predictors were identified using multivariate logistic regression. A total of 303 centres (289 health clinics, 14 hospitals) contributed a total of 70,889 patients (1972 or 2.8% patients were from hospital). About thirty eight percent were reported to have dyslipidaemia. There were 40.7% patients on lipid-lowering agents and of those above age 40 years old, only 38.1% of them were on a statin. Malay ethnicity and younger age groups (<50 years old) were two major determinants of uncontrolled LDL-C, TG and HDL-C. Female gender and uncontrolled blood pressure were determinants of uncontrolled LDL-C, and poor glycaemic control was related independently to high TG. This study has highlighted the suboptimal management of diabetic dyslipidaemia in Malaysia. Pharmacological treatment of dyslipidaemia could be more effective. Healthcare stakeholders in this country, especially in the primary care, have to recognize these shortfalls and take immediate remedial measures.
