    Chinese medicine is one of the most famous traditional medicines in the world with a glorious and long written history of at least 2000 years. Recently, acupuncture and the use of other herbal medicine are being gradually accepted globally. In 2011,the International Medical University (IMU) started the Chinese Medicine programme which is the first of its kind in a western medicine university in Malaysia.The author introduced the background of Chinese medicine and the curriculum of the Chinese Medicine programme established in IMU, analyzed the situation regarding the quality of lectures given by internal and
    external lecturers in this programme and also discussed on ways to integrate western and traditional medicine in IMU or in Malaysia. The launching of Chinese medicine in IMU is a great step in the development of IMU and also an important step in the development of medical education in Malaysia or even in South-east Asia.

    A recently published meta-analysis showed that each additional serving of rice increased risk of type 2 diabetes mellitus (DM) by an alarming 11%. We investigated whether this phenomenon is seen in the Malaysian population by studying the effect of rice intake and added sugar consumption on fasting plasma glucose (FPG) and fasting triacylglycerol (TAG).

    Gestational breast cancer (GBC) or pregnancy-associated breast cancer was defined as breast cancer diagnosed during pregnancy and within 1 year of delivery. Breast cancer is the second commonest cancer after cervical seen in pregnancy and lactation. Nevertheless, the incidence is low and accounts for approximately 1 in 3000 of pregnancies. A delay in diagnosis is common and 70% to 89% of patients with operable primary lesions already have positive axillary lymph nodes. Breast cancer identified during pregnancy can be extremely distressing for the mother despite it has similar course of disease and prognosis seen in non-pregnant women of the same age and stage of disease. Diagnostic and treatment options should be carefully decided to prevent further harm to the mother or any potential risk to the developing fetus.

    Background: Peripheral venous catheterisation is indispensable in modern practise of medicine. The indications of venous access should be weighed against the risk of complications, the commonest being thrombophlebitis. Thrombophlebitis causes patient discomfort and the need for new catheter insertion and risk of developing further widespread infections. Methodology: This observational study was conducted on adult patients admitted to the surgical and medical ward of a tertiary hospital in Negeri Sembilan Malaysia in 2011. Four researchers visited patients daily and examined for signs of thrombophlebitis; warmth, erythema, swelling, tenderness or a palpable venous cord. Risks factors that were studied in this research were patient/s age and gender, duration of catheterization, use of catheter for infusion, size of catheter, site of catheter insertion and types of infusate. Thrombophlebitis was graded using a scale adapted from Bhandari et al. (1979). Results: In total, 428 patients were recruited with an incidence rate of thrombophlebitis of 35.2%. Among those who developed thrombophlebitis, 65% had mild thrombophlebitis, 19% moderate and 8% severe thrombophlebitis. Results showed that female patients had a significant increased risk of developing thrombophlebitis. Also risk increased significantly with increased duration of catheterization and usage of the catheter for infusion. The age of a patient, types of infusate use, size of catheter and site of catheter insertion did not significantly influence the development of thrombophlebitis. Conclusion: The study showed that risk of developing thrombophlebitis is significantly increased among female patients, and also with increased duration of catheterization and use of the peripheral venous catheter for infusion. We recommended elective replacement of catheter every 72 hours and daily examination of catheters for signs of thrombophlebitis by a healthcare personnel.

    Important bioactive molecules are molecules that are pharmacologically active derived from natural sources and through chemical synthesis. Over the years many of such molecules have been discovered through bioprospective endeavours. The discovery of taxol from the pacific yew tree bark that has the ability in stabilising cellular microtubules represents one of the hallmarks of success of such endeavours. In recent years, the discovery process has been aided by the rapid development
    of techniques and technologies in chemistry and biotechnology. The progress in advanced genetics and computational biology has also transformed the way hypotheses are formulated as well as the strategies for drug discovery. Of equal importance is the use of advanced drug delivery vehicles in enhancing the efficacy and bioavailability of bioactive molecules. The availability of suitable animal models for testing and validation is yet another major determinant in increasing the prospect for
    clinical trials of bioactive molecules.

    Appreciation of learning styles can be of use to help both educators and students to enhance the effectiveness of an educational experience. It has been noticed that some students at this College are not very good at expressing themselves in either written or spoken English. Our study aimed to identify the student’s learning styles; assess whether there is any correlation between learning style, baseline demographic data and self rated proficiency in English language; and assess their associations with the assessment performance.
    A group of third year medical students voluntarily participated in a questionnaire study to provide us with their learning styles, demographic information and self-rated proficiency in English language. This data was compared to the students’ performance in the assessment at the end of their junior clinical rotations.
    This cohort of students (60% Malay, 35% Chinese and 5% Indian) who were mostly visual learners, considered themselves proficient in English. Students with predominantly Visual learning styles and those with poorer English, score significantly lower during their clinical long case examinations. These two predictors appear to be independent of each other.
    These results may suggest that our current teaching modalities may disadvantage students with predominant visual learning styles. It also suggests that the long case clinical examination may favour those with more verbal learning styles.

    IMU is one of 17 institutions of higher learning conducting the Bachelor of Pharmacy course
    in Malaysia. The White paper on pharmacy student professionalism by the Task Force of the American Pharmaceutical Association Academy of Students of Pharmacy together with the American Association of Colleges of Pharmacy Council of Deans mentioned10 essential traits of a professional, recommending their early development. Since the beginning of theIMU Bachelor of Pharmacy (BPharm) (Hons) course in July 2004 on Registration Day, IMU has adopted the concept of developing professionalism in the pharmacy student from the very first day of university, by having the White Coat Ceremony where the entire class takes the Pledge of Professionalism (adapted from the Task Force) against the “Code of Conduct for Pharmacists and Bodies Corporate” by the Pharmacy Board of Malaysia in the presence of the Senior Director of the Pharmaceutical Services Division of the Ministry of
    Health, Malaysia and the President of the Malaysian Pharmaceutical Society (MPS). Throughout their 4 years in IMU, the pharmacy students are exposed to various aspects of professionalism in different subjects in their curriculum. On 23rd April 2012, when the fifth cohort of BPharm students received their final examination results, “Pharmacy Professional Day” was launched. The graduating students took the Oath of a Pharmacist (adapted from the American Association of Colleges of Pharmacy’s Oath with slight amendment). Talks by alumni and speakers from MPS aimed to facilitate the transition of the new graduate to working life as a pharmacist.

    The Orang Aslis are indigenous minority peoples of Peninsular Malaysia, numbering 147,412 in 2003.Currently, the Orang Asli are divided into four language groupings namely the Northern Aslian, the Central Aslian, and the Southern Aslian groups, all of whom speak Austroasiatic languages; a fourth group in the South of Peninsular Malaysia speak a Malay dialect belonging to the Austronesian group of languages.This research was carried out on only one of the Northern Aslian group, the Jehai, who are also named Negritos based on their physical features. The Jehai live in the Belum and the Temenggor Forest that straddles Upper Perak and West Kelantan and until recently, were nomadic and lived by hunting-gathering.The World Health Organization (WHO) estimates that approximately two billion people worldwide are infected with the soil-transmitted nematode helminths,Ascaris lumbricoides, Trichuris trichiura and the hookworms Necator americanus and Ancylostoma duodenale, with 400 million of these infected being children of school age.Global numbers of A. lumbricoides infection have been estimated at about 1.5 billion cases. (Crompton, 2001). T. trichiura infection affects approximately 1,049 million people worldwide and an estimated 1.2 billion people are infected by hookworms. In Malaysia, the most common soil-transmitted helminth infections are A. lumbricoides, T. trichiura and hookworms.
    However, as there have been no extensive surveys on these infections, it is difficult to estimate with certainty the current overall incidence of infection with soil-transmitted helminths (STHs) among the Malaysian population.

    Metabonomics can be used to quantitatively measure dynamic biochemical responses of living organisms to physiological or pathological stimuli. A range of analytical tools such as high-resolution nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS) combined with multivariate statistical analysis can be employed to create comprehensive metabolic signatures of biological samples including urine, plasma, faecal water and tissue extracts. These metabolic signatures can reflect the physiological or pathological condition of the organism and indicate imbalances in the homeostatic regulation of tissues and extracellular fluids. This technology has been employed in a diverse range of application areas including investigation of disease mechanisms, diagnosis/prognosis of pathologies, nutritional interventions and drug toxicity. Metabolic profiling is becoming increasingly important in identifying biomarkers of disease progression and drug intervention, and can provide additional information to support or aid the interpretation of genomic and proteomic data. With the new generation of postgenomic technologies, the paradigm in many biological fields has shifted to either top down systems biology approaches, aiming to achieve a general understanding of the global and integrated response of an organism or to bottom up modelling of specific pathways and networks using a priori knowledge based on mining large bodies of literature. Whilst metabolic profiling lends itself to either approach, using it in an exploratory and hypothesis generating capacity clearly allows new mechanisms to be uncovered.

    There has been a significant decline in maternal mortality from 540 per 100,000 live births
    in I957 to 28 per 100,000 in 2010. This decline is due to several factors. Firstly the introduction of the rural health infrastructure which is mainly constructing health centres and midwife clinics for the rural population. This provided the accessibility and availability of primary health care and specially, antenatal care for the women. This also helped to increase the antenatal coverage for the women to 98% in 2010 and it increased the average number of antenatal visits per women from6 in 1980 to 12 visits in 2010 for pregnant women. Along with the introduction of health centres, another main feature was the introduction of specific programmes to address the needs of the women and children. In the 1950s the introduction of Maternal and Child Health (MCH) programme was an important
    step. Later in the late 1970s there was the introduction of the High Risk Approach in MCH care and Safe Motherhood in the 1980s. In 1990, an important step was the introduction of the Confidential Enquiry into Maternal Deaths (CEMD). Another significant factor in the reduction is the identification of high risk mothers and this is being done by the introduction of the colour coding system in the health centres. Other factors include the increase in the number of safe deliveries by skilled personnel and the reduction in the number of deliveries by the Traditional Birth Attendants (TBAs). The reduction in fertility rate from 6.3 in 1960 to 3.3 in 2010 has been another important factor. To achieve the 2015 Millennium Development Goals (MDG) to further reduce maternal deaths by 50%, more needs to be done especially to identify maternal deaths that are missed by omission or misclassification and also to capture the late maternal deaths.

    Bacillus thuringiensis is an anaerobic, spore forming bacterium that produces various toxic proteins both during its vegetative stage and sporulative stage. During its sporulative stage, it produces parasporal proteins that have long been used in the agriculture fields as insecticides. Although anticancer effect of Bacillus thuringiensis parasporal proteins can be dated back to the 1970s, research in this area went through a giant leap in the late 1990s, with much of the work being done in Japan. It has been found that some strains of non-insecticidal Bacillus thuringiensis produce parasporal proteins that exhibit anticancer activity. Due to their selectivity against human cancer cells but not normal cells, some of these proteins have been extensively studied for their anticancer effect and the mechanism of action by which these proteins kill cancer cells have also been widely explored in Japan and Malaysia with sporadic reports from other parts of the world. The abundance of these bacilli in nature and their selectivity have made them potential candidates for cancer treatment. However, literature on the in vivo effect of these proteins is scarce. Since different Bacillus thuringiensis strains produce different cytotoxic proteins with wide variations in their anticancer effect and mechanism of action, further investigations are necessary and their effect in vivo must be well established before they can be used in human subjects.

    There have been significant achievements in research at IMU as indicated by the increasing amount of external funds obtained, and number of publications and postgraduate students produced since it started its research activities in the year 2000. However, it is a great challenge indeed to ensure sustainability of our research, which is currently heavily dependent on internal funding. There is a need to realign our strategies to further enhance our competitiveness in securing external funding for research. In line with this, the Institute for Research, Development and Innovation (IRDI) was officially established on 18 September 2012. The Institute will serve as a platform to support all research activities at IMU. There are four Centres of Excellence based on the identified thrust areas under
    IRDI, namely 1) Centre for Bioactive Molecules and Drug Discovery; 2) Centre for Environmental and
    Population Health; 3) Centre for Cancer and Stem Cell Research, and 4) Centre for Health Professional Education Research. Major findings based on research in these four thrust areas are reviewed in this paper. With the strategic planning and establishment of IRDI, it is our aspiration to bring research at IMU to a higher level.

    Morning surge in blood pressure is an independent cardiovascular risk factor in the middleaged and the elderly. Whether such a surge occurs in young subjects is not known. Eighty normotensive subjects (age: 21.8 ± 1.3 yr) measured their own blood pressure (BP) using an automatic device (Omron HEM-7080,) on going to bed and on waking up, for 2 consecutive days. In contrast to large morning BP surges reported for older age groups, there was much smaller but significant (P

    Community-acquired pneumonia (CAP) is one of the most common infectious diseases and the world’s leading cause of mortality and morbidity, especially in patients aged 65 years and above.1,2 It is the 6th cause of mortality and the most important cause of hospitalisation in Malaysia. According to the British Thoracic Society, the gold standard in diagnosing CAP is based on radiological findings and it is defined into 2 different settings – community and hospital.3

    Consent is defined as the “voluntary agreement to or acquiescence in what another person proposes or desires”. In the context of medical practice it is now universally accepted that every human being of adult years and of sound mind has the right to determine what shall be done with his or her own body. Informed consent is now a central part of medical ethics and medical law. There has been a change in the public’s expectations of their role in medical decision making. The paternalistic approach by doctors is no longer acceptable. Today the patient has the right to receive and the doctor the obligation to give sufficient and appropriate information so that the patient can make an informed decision to accept or refuse a treatment option. This has led to higher standards of practice in the process of informed consent taking. Consent taking is both a legal and moral requirement. Failure to comply with standards of practice can result in criminal prosecution, civil litigation or disciplinary action by the relevant professional authority. Consent taking is a process and not merely a one-off affixation of the patient’s signature on consent form. It involves a continuous discussion to reflect the evolving nature of treatment from before the treatment is given to the post-operative or discharge period. The regulatory authorities in many countries have established standards for consent taking which would include the capacity of the patient, the person who should seek consent, the information to be provided and the necessary documentation.

    Background: Clinical reasoning is the name given to
    the cognitive processes by which doctors evaluate and
    analyse information from patients. It is a skill developed
    by experiential learning and is difficult to assess
    objectively. The script concordance test, an assessment
    tool introduced into the health sciences about 15 years
    ago, is a way of assessing clinical reasoning ability in
    an objective manner and allows comparisons of the
    decisions made by medical students and experts in
    situations of uncertainty.

    Methods: Twenty-six final year medical students from
    the International Medical University, Kuala Lumpur,
    were tested on their decision making skills regarding a
    young febrile patient. The students evaluated different
    pieces of information in five different scenarios and
    made decisions on a five-point Likert scale in the
    standard format of the script concordance test. Their
    decisions were compared to the decisions of a panel of
    experienced clinicians in Internal Medicine.

    Results: The script concordance test scores for the
    different scenarios were calculated with higher scores
    being indicative of greater concordance between the
    reasoning of students and doctors. The students showed
    poor concordance with doctors in evaluating clinical
    information. Overall, only 20 percent of the choices
    made by students were the same as the choices made by
    the majority of doctors.

    Conclusion: Medical students vary in their ability to
    interpret the significance of clinical information. Using
    the script concordance test, this preliminary study looked
    at the ability of final year medical students to interpret
    information about a patient with a febrile illness. The
    results showed poor concordance between students and
    doctors in the way they interpreted clinical information.
    The script concordance test has the potential to be a
    tool for teaching and assessing clinical reasoning.

    Rheumatoid arthritis (RA) is a chronic
    inflammatory condition that can be associated with
    abnormal bone turnover and hence osteoporosis.
    Osteocalcin (OC) levels are increased in conditions
    with high bone turnover, including high RA disease
    activity. Thus, OC levels could possibly be used as a
    marker to assess bone health and disease activity in RA
    patients. As there have been no previous studies looking
    at serum OC levels in Malaysian RA patients, this study
    was performed to examine possible correlations between
    OC, bone mineral density (BMD) and disease activity
    in this population. A cross-sectional study of 75 female RA
    patients and 29 healthy controls was performed. Serum
    OC was measured using a Quantikine® ELISA kit. Dualenergy
    x-ray absorptiometry (DXA) was used to assess
    BMD. Serum OC levels were not significantly
    different between RA patients (median 14.44 ng/mL,
    interquartile range [IQR 12.99]) compared to healthy
    controls (median 11.04 ng/mL IQR 12.29) (p=0.198).
    Serum OC increased with age (Spearman’s rho r=0.230,
    p=0.047). There was no significant correlation between
    serum OC and body mass index (BMI), menopause status,
    BMD, DAS28, swollen or tender joint counts. Overall,
    there were 11 (14.7%) patients with osteoporosis and
    27 (36.0%) with osteopenia. Menopause status was
    significantly associated with BMD at all sites (lumbar
    spine p=0.002, femoral neck p=0.004, total hip p=0.002).
    Serum OC were similar in RA patients
    compared to healthy controls. In RA patients, serum
    OC did not correlate with RA disease activity or BMD.
    Menopause status remains an important influence on
    BMD. Thus, measuring serum OC levels in Malaysian
    RA patients was not useful in identifying those at risk
    of low BMD.

    This paper reviews available reports on the omega-6 (linoleic acid, LA) and omega-3 fatty acid
    [alpha-linolenic acid (ALA) + eicosapentaenoic acid (EPA) + docosahexaenoic acid) intakes amongst Malaysians against Malaysian Recommended Nutrient Intakes (RNI), focussing particularly on pregnant and lactating women because of the availability of data for these latter vulnerable groups. Overall, the omega-6 and omega-3 fatty acid nutrition amongst Malaysians are poor and far from desirable. The nutritional situation regarding these long-chain polyunsaturated fatty acids
    (LCPUFA) amongst Malaysian pregnant and lactating women is alarming and warrants urgent attention in nutrition promotion activities/counselling. Daily consumption of LA by these women and other Malaysians studied ranged from 3.69 - 5.61 % kcal with 38-60% of individuals not meeting their RNIs. Daily intakes of omega-3 fatty acids faired worse, averaging 0.21- 0.33 % kcal with as high as 92% of subjects in one study not meeting their RNIs. The omega-6 to omega-3 fatty acid
    ratios obtained in the studies reviewed are about 20:1, which is way above the World Health Organisationrecommended ratio of 5-10:1. Dietary sources of these omega- fatty acids in the subjects studied are chicken, fish and milk. Since local foods are not particularly rich in LCPUFA such as EPA and DHA, the options to improve EPA/DHA nutrition amongst Malaysians are
    the greater consumption of omega-3 enriched foods and in the case of pregnant and lactating women, LCPUFA supplementation may warrant serious consideration.

    In pregnancy, the diagnosis of primary hyperparathyroidism (PHP) may be delayed due to physiological changes that occur during this period. The maternal related complications of PHP during pregnancy has been reported to be as high as 67%, whilst fetal complications up to 80% of cases.1 The therapeutic gold standard and definitive treatment for PHP in pregnancy is minimally invasive parathyroidectomy in the second trimester. We report a case of a 22-year old primidgravida who underwent parathyroidectomy in the third trimester of her pregnancy for PHP with persistent hypercalcemia. She was also found to have Vitamin D deficiency which probably led to secondary hyperparathyroidism and made her hypercalcemia more apparent during pregnancy

    Background: Clinical clerkship in a busy hospital environment forms an important part of undergraduate medical training. Regular objective assessment of this activity with feedback would be expected to improve outcome.

    Methods: We implemented fortnightly clinical assessments using modified OSLER (Objective Structured Long Examination Record), and over a 6-week clinical rotation. Modifications included provision of individualized feedback. The assessment process was evaluated by both students and teachers via a questionnaire measuring their perceived educational impact, feasibility and acceptability.

    Results: Students agreed that the patient spectrum was appropriate and fair, resulting in improved history taking and presentation skills (96.6%), clinical examination skills (89%) and clinical reasoning skills (90.7%). It was graded to have helped learning “tremendously” and “moderately” by 64.7% and 32.8% of students respectively. Perceived improvement was attributable mainly to the repetitive nature of the assessments since only 63% of students were provided with feedback. 96.6% of students and 94.1% of assessors perceived the format created a stressful but positive learning environment. 52.9% of assessors agreed that the exercise consumed significant time and resources but 88.2% rated it as manageable and supported its continuation.

    Conclusion: Frequent and regular in-course clinical assessments with emphasis on individual feedback is feasible, acceptable and has significant positive educational impact.
