Dengue is a serious mosquito borne disease common in tropical and sub-tropical countries including Malaysia.
There is at present a lack of specific treatment and an effective tetravalent vaccine against dengue. The control
of dengue depends solely on the suppression of the two most important vectors namely, Aedes aegypti and Ae
albopictus. Despite intensive and extensive control efforts by health agencies, the disease continues to spread.
This paper updates various innovations on control of dengue vectors. Gene-based sterile insect technique
using the RIDL technology for both Aedes aegypti & Ae albopictus control has now been actively researched and
field trials are pursued to evaluate the effectiveness of the technology. The release of Wolbachia-infected Ae
aegypti is another dengue control innovation. The infected mosquito cannot support development of dengue
virus and has shorter life span. Other innovations include: auto-dissemination of insect control agents using
ovitrap, autocidal adult and larva trap, outdoor residual spraying, insecticidal paint and biocontrol agent. In
other innovation, outbreak prediction capability is enhanced by developing model based on environmental data
and analysis utilising neural network.

Increasing incidence of musculoskeletal injuries coupled with limitations in the current treatment options have necessitated tissue engineering and regenerative medicine- based approaches. Moving forward from engineering isolated musculoskeletal tissues, research strategies are now being increasingly focused on repairing and regenerating the interfaces between dissimilar musculoskeletal tissues with the aim to achieve seamless integration of engineered musculoskeletal tissues. This article reviews the state-of-the-art in the tissue engineering of musculoskeletal tissue interfaces with a focus on Singapore's contribution in this emerging field. Various biomimetic scaffold and cellbased strategies, the use of growth factors, gene therapy and mechanical loading, as well as animal models for functional validation of the tissue engineering strategies are discussed.

Hypercholesterolemia is an important modifiable risk factor for coronary heart disease. Lifestyle changes in diet and physical activity can improve cholesterol levels. This study aimed to compare the fruits and vegetables (FV)
intake and physical activity (PA) between hypercholesterolemic adults and nonhypercholesterolemic
adults in Malaysia, and to investigate factors associated
with meeting the recommended levels of FV intake and PA in a hypercholesterolemic population. Methods: This study was based on 17,988 participants (response rate 98.7%) aged 18 years and above who responded to the hypercholesterolemia questionnaire in the 2011 Malaysian National Health and
Morbidity Survey (NHMS), a cross-sectional study with two-stage stratified sampling design. Data were obtained by trained enumerators via face-to-face interviews and were analysed by descriptive analysis, chi-square test, and
univariable and multivariable logistic regression. Results: Out of the total population assessed, 39.0% had hypercholesterolemia. The prevalence of consuming five or more servings of FV per day is low (7.8%) while 36.0% were
physically inactive among the hypercholesterolemic adults. No significant differences were observed in FV intake and PA between hypercholesterolemic and non-hypercholesterolemic populations. Gender, age and educational levels were associated with FV intake and PA among hypercholesterolemic adults. Hypercholesterolemic adults who were underweight or obese were less likely
to consume FV, while those who were former smokers and those who had diabetes and heart disease were less likely to be physically active. Conclusion: These findings are relevant for future health promotion strategies, suggesting
that more intensive interventions are needed to increase FV intake and PA level in hypercholesterolemic population and in the general population.
