We investigated the association between housing conditions with a primary focus on basic housing infrastructure and WHOQOL BREF score among the Orang Asli and non-Orang Asli populations. A cross–sectional study was conducted between August 2014 and May 2015 among the Orang Asli and non-Orang Asli populations in Kuala Langat, Selangor. Sampling of the population was done through multistage sampling while eligible respondents participated conveniently. The socio-demographic information collected consisted of age, ethnicity, marital status, educational level, and employment status. Basic housing infrastructure variables including the types of housing unit, wall construction material, availability and types of toilet, availability of electricity, source of water supply, and availability of garbage collection facilities were obtained. Among the Orang Asli respondents, having the pour type of toilet in the house was significantly (p=0.003) associated with a reduction in the physical health domain score by 0.36 (95% CI: -0.61,-0.12). Conversely, having no toilet in the house and living in a semi-detached house had significantly (p=0.023 and p=0.026 respectively) increased the social relationships domain score by 0.81 (CI: 0.11, 1.51) and 3.90 (CI: 0.47, 7.34) respectively. Unavailability of garbage disposal facilities was found to be significantly (p<0.001) associated with a reduction in the environmental domain score by 0.70 (95% CI: -1.05, 0.35). This study have added to the evidence that housing programs of the Orang Asli population need to be further strengthened and supported by a range of policies and practices that address the critical intervention points for more potential health gains.

Cultural attitudes of the societies have long been identified as one of the important determinants of Quality of Life (QoL). Yet there is a dearth of socio-culturally validated instruments for local population to assess the impact of socio-cultural practice on health. The aim of this validation study is to develop and test the validity and reliabilityof a questionnaire on culture dimensions.Respondents were asked about their engagement in socio-cultural aspects including beliefs and practice oftraditional customs and culture using a set of newly developed questionnaire.A total of 275eligible respondentsparticipatedwith150(54.5%)from the general population and 125 (45.5%)from the Orang Asli population. Kaiser-Meyer Olkin measure of Sampling Adequacy (KMO) was 0.791 and 0.677 for the general and Orang Asli population respectively. Bartlett’s test for both population was significant (p<0.001). By Principal Common Analysis, four factorswere extracted (Eigen values >1.0) that jointly accounted for 54.7% and 52.0% of the total variance among the general population and Orang Asli respectively.The Cronbach alpha value score was 0.785and 0.730 for the general population and Orang Asli population respectively. The Cronbach alpha values foreach of the four domains ranged from 0.477-0.865 and 0.543-0.758 for the general population and Orang Asli population respectively.These results suggest that the newly developed questionnaire appeared to have adequate validity and reliability in measuringsocio-cultural factors in the population.

Routine diagnosis of intestinal microsporidiosis in clinical diagnostic laboratories relies mostly on
detection of microsporidial spores via special staining and microscopic techniques. This paper describes
the comparative evaluation of Calcofl uor White M2R method, with modifi ed Gram-chromotrope
Kinyoun method as the reference standard. One hundred and six stool samples were examined for the
presence of microsporidial spores. Sensitivity, specifi city, positive and negative predictive values of
the Calcofl uor White M2R method compared to the reference technique were 95.2%, 4.3%, 78.2%
and 20.0%, respectively. The positive predictive value (PPV) was 78.2% and the negative predictive
value (NPV) was 20.0%. Despite low specifi city of the CFW method due to its ability to stain
chitinous wall of microorganisms, the presence of distinct deep-blue horizontal or equitorial stripes in
microsporidial spores in modifi ed Gram-chromotrope Kinyoun would likely reduce the false positive
results obtained in the Calcofl uor White M2R. Hence, the simultaneous use of these two methods
would give better performance and accuracy for the detection of microsporidial spores in patients
with intestinal microsporidiosis.

Essential oil from Cymbopogon nardus was evaluated for activity against
Trypanosoma brucei brucei BS221 (IC50 = 0.31 ± 0.03 μg/mL) and cytotoxic effect on normal
kidney (Vero) cells (IC50 = >100 μg/mL). The crude essential oil was subjected to various
chromatography techniques afforded active sub fractions with antitrypanosomal activity; F4
(IC50 = 0.61 ± 0.06 μg/mL), F6 (IC50= 0.73 ± 0.33 μg/mL), F7 (IC50 = 1.15 ± 0 μg/mL) and F8
(IC50 = 1.11 ± 0.01 μg/mL). These active fractions did not exhibit any toxic effects against
Vero cell lines and the chemical profiles investigation indicated presence of α-and γ-eudesmol,
elemol, α-cadinol and eugenol by GC/MS analysis.

Behavioural change interventions for weight loss have been found to be effective in the short term, but their long-term effectiveness remains a question. The objective of this study was to evaluate the effectiveness of the 36 weeks F.E.A.T program combining behavioural changes of healthy eating and physical activity. A quasi-experimental study of overweight adults was conducted in Malacca. A total of 53 subjects (mean age 47.4 ± 7.2 years) completed the program in three stages. In the first stage (T1: weeks 1–12), the intervention group (n = 28) participated in the F.E.A.T program activities, while the control group (n = 25) did not receive the intervention. In the second stage (T2: weeks 13-24), the activity was supervised and monitored by the peer support group. Sustainability of activity was measured at the third stage (T3: weeks 25-36). The effectiveness of the program was measured by changes in dietary intake, physical activity score, body weight, body mass index (BMI), waist circumference (WC) and body fat percentage at T0 (pre-intervention), T1, T2 and T3. All parameters showed significant interaction effects (time*group) except for energy intake. The intervention group showed significant decreases from T0 to T3 for energy intake (-14.3%), body weight (-4.3%), BMI (-4.2%), WC (-10.5%) and body fat percentage (-3.6%). While physical activity level increased by 109.6% for the intervention group. There were no significant differences in all of these parameters among the control group. The results show the effectiveness of the F.E.A.T program on dietary status and physical activity changes during the 36-week of intervention period.

Trypanosoma brucei parasites are flagellated kinetoplastid protozoan which is responsible for Human
African Trypanosomiasis (HAT). Current chemotherapy drugs have a number of side effects and drug
resistance has emerged as a major issue in current treatment. Active bisindole alkaloid compound
ochrolifuanine was previously isolated from the leaves of Dyera costulata. In vitro antitrypanosomal
activity of ochrolifuanine against Trypanosoma brucei brucei strain BS221 showed strong activity with
an IC50 value of 0.05 ± 0.01 µg/ml. We compared the effect of ochrolifuanine and reference compound
staurosporine in T. b. brucei apoptosis. The apoptosis-inducing activity of ochrolifuanine was evaluated
using TUNEL assay and cell cycle analysis. Trypanosoma brucei brucei was shown to undergo apoptotic
cells death as demonstrated by the appearance of several conical hallmarks of apoptosis. Ochrolifuanine
was found to induce apoptosis in parasites in a dose- and time-dependent manner. The cell cycle study
revealed 0.025 and 0.05 µg/ml of ochrolifuanine arrested the growth of T. b. brucei at two different
growth phases (G0/G1 and in S phases). While at concentration 0.10 µg/ml arrested at the G2/M phase.
In conclusion, the results indicate that ochrolifuanine displayed an antitrypanosomal effect on T. b. brucei
by inducing apoptosis cell death and causing the arrest of parasite cells at different growth phases. The
results suggested that ochrolifuanine may be a promising lead compound for the development of new
chemotherapies for African trypanosomiasis.
