OBJECTIVEThe aim of this review is to objectively access the trial evidence on the role of omega-3, red yeast rice and garlic in preventing clinical cardiovascular events. Given the large number of clinical trials favoring statin use in cardiovascular disease, it is important to see if evidence is available for these supplements and whether they could replace statin therapy.
DATA SOURCEA PubMed search was conducted using the keywords 'trial, omega-3, red yeast rice, xuezhikang, garlic, cholesterol, cardiovascular, outcomes'; the resulting trials were reviewed together with the references quoted in the papers obtained.
STUDY SELECTIONThe studies selected are prospective, randomized, placebo-controlled studies with predefined clinical cardiovascular end-points recruiting at least 2000 patients, with a follow-up over 2 years.
RESULTSModest dose omega-3 fatty acid has been shown in GISSI-P (11 324 patients, follow-up 3.5 years) to produce a reduction in sudden death of 45%, and in cardiac death of 35%, acting probably via an anti-arrhythmic effect. In JELIS (18 645 patients, follow-up 4.6 years), high dose omega-3 given to Japanese patients on a high fish diet and already on statin treatment produced further benefit with a 19% reduction of nonfatal cardiovascular outcomes; fatal cardiac events are not affected. CCSPS (4870 patients, follow-up 4 years), a secondary prevention trial using xuezhikang, a commercial red yeast rice preparation, produced a 46% reduction in nonfatal myocardial infarction and coronary death. There has been no trial to show that garlic reduces clinical cardiovascular outcomes. A rigorous trial with constant assessment of chemicals in the study material in 192 patients found that over a 6-month follow-up, raw garlic and 2 commercial preparations do not significantly affect lipid levels.
CONCLUSIONSOmega-3 in modest doses reduces cardiac deaths, and in high doses reduces nonfatal cardiovascular events. Red yeast rice reduces adverse cardiac events to a similar degree as the statins. It is unlikely that garlic is useful in preventing cardiovascular disease.

INTRODUCTIONMedical talks, newsletter circulars, scientific meetings and conferences, and interaction with members of the pharmaceutical industry, have become convenient means of carrying out continuing medical education (CME) for many busy doctors.
MATERIALS AND METHODSTo study the perceived importance of these various CME activities, a self-completed posted questionnaire survey was conducted among registered practitioners of a densely populated urban state in Malaysia.
RESULTSOf the 172 respondents [male, 77%; hospital-based, 37%; general practitioner (GP), 55%; private practice, 70%; respondent rate of 19.5%], most preferred local conferences and endorsements by local experts to their foreign counterparts. Meetings or conferences sponsored by the pharmaceutical industry were ranked similarly with those without such links, while the reputation of the pharmaceutical firms was of foremost importance. Among GPs (n = 95) and non-GPs (n = 77), medical society newsletters were rated significantly higher by GPs while overseas conferences were rated higher by non-GPs.
CONCLUSIONOur findings provide an important first look at this under-explored area among Malaysian doctors and described a high degree of acceptance for the involvement of the pharmaceutical industry in CME activities.

Introduction: Awareness for paediatric palliative care has
resulted in the impetus for paediatrician-led palliative care
services across Malaysia. However, there is paucity of local
data on patients receiving hospital-based paediatric
palliative care. We aim to review the clinical spectrum of
patients referred to these services.
Methods: An observational study of children aged between
0-18 years receiving palliative care at 13 hospitals between
1st January and 31st December 2014 was carried out.
Results: There were 315 patients analysed, 90 (28.6%) and
46 (14.6%) were neonates and adolescents respectively. The
main ICD-10 diagnostic categories for all patients were
identified to be ‘Congenital malformations, deformations
and chromosomal abnormalities’ 117 (37.1%), ‘Diseases of
nervous system’ 76 (24.1%) and ‘Neoplasms’ 60 (19.0%). At
referral 156 (50%) patients had holistic needs assessments.
Patients with ‘Diseases of nervous system’ were assessed
to have significantly more physical needs than the other two
diagnostic categories. Majority of patients who knew of their
diagnosis and prognosis were those with malignancy. Over
a fifth of referrals were at their terminal admission. Of 144
who died, 111 (77.1%) had advanced care plans. There was
bereavement follow-up in 98 (68.1%) patients.
Conclusion: Patients referred for palliative care have varied
diagnoses and needs. To ensure all paediatricians are
competent to deliver quality care to all children, further
education and training initiatives is imperative.
