Hydroxyapatite, (HA; Ca1O(PO4)6(OH)2) has been successfully applied in medical and dental applications for several years due to its excellent biocompatibility. The usage of HA in Malaysia, however, is limited due to the lack of availability. Therefore the aim of this work is to produce HA materials from both pure chemicals and from Malaysian natural limestone precursors, and to compare their bulk properties. However, parts of Malaysian natural limestone deposits actually consist of a combination of Ca(OH)2 and CaCO3. In order to utilise the limestone to produce HA material, the combination of these commercially pure chemicals as HA precursors should still work. In order to test this hypothesis, two HAs were produced by wet synthesis technique utilising (a) combination of Ca(OH)2 + CaCO3 from pure commercial chemicals [WCC] and (b) a local natural limestone [WL] precursors. The HAs produced; WCC and WL, were compacted into discs and sintered at 1250 degrees C. The characterisations and evaluations conducted were XRD, SEM-EDX, FTIR and shrinkage factor. The results indicate that WL gives slightly better bulk properties compared to WCC.

Poly (p-phenylene vinylene) (PPV) was synthesized from p-xylylene bis(tetrahydrothiophenium chloride) using the Wessling route and characterized by Fourier Transform Infra-Red (FTIR) and UV-visible (UV-VIS) spectroscopic techniques. The significance of thermal treatment along with evolution of precursor polymer to polymer PPV was also studied through these spectroscopic techniques. Thermally Stimulated Current (TSC) measurements indicated the presence of crystallization, sulphonium group which occurred through the evolution from precursor polymer to polymer PPV during thermal treatment.

Serological confirmation of dengue in 1,410 school-going children aged 7-18 years
provided prevalence data for 16 different sites in Malaysia. These sites ranged from highly
urbanized cities to small towns. We found that at least ~7 % of children in the study group had
been exposed to dengue by age 12 and ~16% by age 18. Here we report that the dengue
seroprevalence correlates with i) increasing land development and decreased vegetation,
and ii) the overall population growth. Water bodies did not significantly affect dengue
prevalence. High prevalence of dengue was also recorded in few of the non-urban sites
suggesting the expanding geographical locality of those who get dengue in Malaysia in
tandem with increased land usage activities. These findings highlight the need to give closer
consideration to future urban planning and development, taking into consideration the
changing demography and the importance of built environment to mitigate the increasing
incidence of dengue in the non-urban areas of Malaysia.

9.Descriptive Analysis of Type 2 Diabetes Mellitus Patients Using Data From Hospital Information System
Malaysian Journal of Medicine and Health Sciences 2020;16(No.1):94-99
Electronic medical records from hospital information system (HIS) offer a major potential for secondary
data analysis which can improve the efficiency of healthcare delivery. This study describes an initiative to use HIS
data to explore the level of diabetic care in patients with T2DM in a hospital-based outpatient clinic, the advantages
and challenges in utilising HIS data. Methods: Patients age of 18 and above who received any diabetes medication
in 2013 were retrospectively identified from HIS of Serdang Hospital. Demographic characteristics, anti-diabetic
agent (ADA) dispensed, and glycaemic measures were quantified. Data was extracted using structured query language (SQL) and descriptive statistical analyses were conducted using Stata Version 12. Results: Prevalence of T2DM
patients in the hospital was 7.5%. Male had slightly higher prevalence and patient at age of 61-70 years old. About
62% of patients were prescribed with metformin and 5% of newer combination of oral hypoglycemic agent. In prescribing pattern, stratification by age group, showed that patient age 41 to 70 years received mostly monotherapy,
whilst 61.1% continue their regime for the year. Only 18% obtained good glycaemic control. Conclusion: Hospital
Information system is a critical instrument in providing data as a platform in diabetic care in an outpatient care.
Moving forward, steps to improve HIS should be taken to seize its potential as a tool to increase the efficiency of
healthcare delivery.
10.Ultrastructural changes of cell morphology and viral morphogenesis of two ecotypes of dengue virus infection in human monocytic U-937 cell

Dengue virus (DENV) is maintained and circulated in both sylvatic/enzootic and
endemic/human cycles and spill over infection of sylvatic DENV into human populations has
been reported. Extensive deforestation and increase human activities in forest may increase
the risk of human exposure to sylvatic dengue infection and this may become a threat to
human. Present study investigated the changes in cell morphology and viral morphogenesis
upon infection with sylvatic and endemic ecotypes in human monocytic U-937 cells using
transmission electron microscopy. Autophagy, a process that is either pro-viral or anti-viral,
was observed in U-937 cells of both infections, however only the replication of endemic
DENV was evidenced. An insight into the infection responses of sylvatic progenitors of DENV
in susceptible host cells may provide better understanding on dengue emergence in human
populations.
