    Data are presented from a long-term study of banded langurs in three contrasting rain forest habitats in Peninsular Malaysia. Results from different sites and months are used to correlate ranging patterns with food availability and other environmental variables. Day range lengths are correlated with availability of preferred foods; the degree of territoriality is related to the distribution and size of food sources and length of time for which any one of these produces favoured food items.

    OBJECTIVE:This study aimed to assess the knowledge, awareness, and perception of contraception among senior pharmacy students of a public sector university in Malaysia.
    METHODS: A cross-sectional, questionnaire-based study was conducted among senior pharmacy students. The pretested questionnaire was used to collect data from the participants over the period of 1-month. The questionnaire was divided into four sections, for gathering the information about students' demographic data, and their knowledge, attitudes, and perception toward contraception. Data were statistically analyzed using SPSS version 20.
    FINDINGS: The response rate was 68.6%. The results showed that the contraceptive knowledge was comparatively higher in year four students (P < 0.001), married respondents (P < 0.001) and those taking elective courses (P = 0.022) as compared to their respective counterparts. Majority of the students were well aware and had a positive perception about contraception.
    CONCLUSION: Overall findings reflect that the majority of the students had good knowledge, perception, and awareness about contraception. The study recommends future studies to be conducted covering different pharmacy schools across the country to further establish the results.

    Street food in NST province is crucial for the people due to the changing of lifestyles. The
    consumers demand enhances the number of street vendors in the province. Nevertheless, there
    are vendors that are not practicing good hygienic compared to other province. The objectives
    of this study are to identify the pattern of street food consumption, and consumers’ opinion
    towards the street food. Observation and in-depth interview were used to collect data. Ten
    respondents with various demographic backgrounds were interviewed on their experiences,
    and opinions toward street food. The data found that the street food consuming pattern was
    formed in six major themes: consumer characteristic, type of food, location, time of consuming,
    ways to consume and reasons of consuming. Additionally, the study also declared consumer’s
    opinion on the problems related to street food. The finding aims local authority to have more
    understanding on the culture of street food consumption, and the problems that have been
    existed to find the appropriate improvement, and do not induce any conflict between local
    authority with street vendors and authority with consumers.

    BACKGROUND/OBJECTIVE: Postoperative pancreatic fistula (POPF) remains an important cause of morbidity and mortality after pancreaticoduodenectomy. Pancreaticogastrostomy (PG) as a reconstruction method after pancreaticoduodenectomy is a safe and optional surgical technique in decreasing the risk of POPF. In this study, a retrospective analysis was carried out to evaluate a new modification of PG technique that uses a two-layer anastomoses with an internal stent.

    METHODS: Forty-seven patients underwent this newly modified PG technique between February 2012 and August 2016. Demographics, histopathological findings, type of surgery performed, perioperative parameters, postoperative length of stay, postoperative complications and interventional procedures, follow-up, and mortality data were collected and analyzed. Clavien-Dindo classification was used to grade the complications' severity.

    RESULTS: Postoperative mortality was 4.25%, unrelated to POPF, and postoperative morbidity was 44.68%. Thirteen patients had severe (>Grade IIIa) complications, according to Clavien-Dindo classification. As classified in accordance to the International Study Group of Pancreatic Fistula, 24 (51.06%) patients developed Grade A POPF, and no occurrence of Grade B/C POPF was noted. All patients recovered uneventfully with successful treatment interventions.

    CONCLUSION: The reported PG anastomotic technique is a safe and dependable reconstruction procedure with acceptable morbidity and mortality.

    The 2015 National Health and Morbidity Survey estimated that over 29% of the adult population of Malaysia suffers from mental distress, a nearly 3-fold increase from the 10.7% estimated by the NHMS in 1996 pointing to the potential beginnings of a public health crisis. This study aimed to better understand this trend by assessing depressive symptoms and their correlates in a cross-section of Malaysians. Specifically, it assesses stress, perceived locus of control, and various socio-demographic variables as possible predictors of depressive symptoms in the Malaysian context. A total of 728 adults from three Malaysian states (Selangor, Penang, Terengganu) completed Beck's depression inventory as well as several other measures: 10% of respondents reported experiencing severe levels of depressive symptoms, 11% reported moderate and 15% reported mild depressive symptoms indicating that Malaysians are experiencing high levels of emotional distress. When controlling for the influence of other variables, depressive symptoms were predictably related to higher levels of stress and lower levels of internal locus of control. Ethnic Chinese Malaysians, housewives and those engaged in professional-type occupations reported less depressive symptoms. Business owners reported more depressive symptoms. Further research should look more into Malaysians' subjective experience of stress and depression as well as explore environmental factors that may be contributing to mental health issues. It is argued that future policies can be designed to better balance individual mental health needs with economic growth.

    This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made."

    In Peninsular Malaysia child mortality rates (5q0) vary from 13 to 63 per thousand at district level. The spatial pattern is closely associated with the regional distribution of socio-economic factors. But due to multicollinearity it is difficult to isolate the influence of socio-economic variables from other variables by employing aggregated data. However, individual data collected in a case-control-study that was conducted in Perlis and Kuala Terengganu confirm the important role of socio-economic factors. So it should be possible to achieve a further reduction of child mortality by raising the income and educational level of the under-privileged groups. Apart from that, as the case of Perlis shows, the provision of family planning and preventive medical services may also contribute to lower child mortality independent from socio-economic changes. But, as the comparison with Kuala Terengganu shows, the utilization of family planning and preventive medical services is not only influenced by the accessibility to, but also by the socio-culturally determined acceptability of such services.

    We investigated the genetic structure within and among Bornean orang-utans (Pongo pygmaeus) in forest fragments of the Lower Kinabatangan flood plain in Sabah, Malaysia. DNA was extracted from hair and faecal samples for 200 wild individuals collected during boat surveys on the Kinabatangan River. Fourteen microsatellite loci were used to characterize patterns of genetic diversity. We found that genetic diversity was high in the set of samples (mean H(E) = 0.74) and that genetic differentiation was significant between the samples (average F(ST) = 0.04, P < 0.001) with F(ST) values ranging from low (0.01) to moderately large (0.12) values. Pairwise F(ST) values were significantly higher across the Kinabatangan River than between samples from the same river side, thereby confirming the role of the river as a natural barrier to gene flow. The correlation between genetic and geographical distance was tested by means of a series of Mantel tests based on different measures of geographical distance. We used a Bayesian method to estimate immigration rates. The results indicate that migration is unlikely across the river but cannot be completely ruled out because of the limited F(ST) values. Assignment tests confirm the overall picture that gene flow is limited across the river. We found that migration between samples from the same side of the river had a high probability indicating that orang-utans used to move relatively freely between neighbouring areas. This strongly suggests that there is a need to maintain migration between isolated forest fragments. This could be done by restoring forest corridors alongside the river banks and between patches.

    BACKGROUND: The effect of dialysis treatment is complex, with both clinical and socio-psychological effects. In this study, we aimed to assess the psychological status of this growing population of end-stage renal disease.

    METHODS: Using the Short Form of Depression, Anxiety and Stress Scale (DASS21) questionnaire, we aimed (1) to measure the psychological states of hemodialysis (HD) or peritoneal dialysis (PD) subjects from 15 sites, (2) to compare DASS21 scores between HD and PD, and (3) to identify the associated demographic and medical factors of better psychological states.

    RESULTS: A total of 1,332 were eligible for analysis. Stress (48%) recorded the highest negative emotional states, followed by depression (37%) and anxiety (20%). By multivariate analysis, normal body mass index weight status, religion and absence of coronary artery disease were associated with lower score for depression, anxiety and stress, respectively. Tertiary education was associated with the lowest score in depression and anxiety, whereas HD had a lower score in stress than PD. A younger age was associated with worse DASS21 score of anxiety and stress.

    CONCLUSIONS: Obesity, religion and coronary artery disease were significantly associated with all 3 symptoms of depression, anxiety and stress. Older age has a protective effect on anxiety and stress. Further study is needed to evaluate the relationship between these significant factors and each psychological state.

    The role of conspecific density dependence (CDD) in the maintenance of species richness is a central focus of tropical forest ecology. However, tests of CDD often ignore the integrated effects of CDD over multiple life stages and their long-term impacts on population demography. We combined a 10-year time series of seed production, seedling recruitment and sapling and tree demography of three dominant Southeast Asian tree species that adopt a mast-fruiting phenology. We used these data to construct individual-based models that examine the effects of CDD on population growth rates (λ) across life-history stages. Recruitment was driven by positive CDD for all species, supporting the predator satiation hypothesis, while negative CDD affected seedling and sapling growth of two species, significantly reducing λ. This negative CDD on juvenile growth overshadowed the positive CDD of recruitment, suggesting the cumulative effects of CDD during seedling and sapling development has greater importance than the positive CDD during infrequent masting events. Overall, CDD varied among positive, neutral and negative effects across life-history stages for all species, suggesting that assessments of CDD on transitions between just two stages (e.g. seeds seedlings or juveniles mature trees) probably misrepresent the importance of CDD on population growth and stability.

    "This paper estimates a proportional hazards model for the timing of age at marriage of women in Malaysia. We hypothesize that age at marriage responds significantly to differences in male and female occupations, race, and age. We find considerable empirical support for the relevance of economic variables in determining age at marriage as well as evidence of strong differences in marriage patterns across races."

    Background and Objective: There is a lack of international collaborative studies on young adults with ischaemic stroke in Asia. The aim of this study was to investigate risk factors, aetiology and outcome at hospital discharge of these patients across 8 participating countries in Asia. Methods: This was a prospective, observational, multicentre, hospital based cohort study. Consecutive young stroke patients with confirmed cerebral infarction between the ages of 18-49 were recruited from December 2011 to May 2012. Data was collected for patient demography, risk factors, investigations, clinical profile and TOAST classification. Outcome measures were death and independence (modified Rankin score≤ 2) at hospital discharge. Results: Two hundred and eighteen patients with the mean age was 40.8±6.7 years were recruited. There was a larger proportion of male patients with a ratio of 1.9:1. Traditional risk factors observed were hypertension (n=103; 47.3%), dyslipidaemia (n=93; 42.4%), smoking (n=85; 38.8%), diabetes (n=53; 24.3%), alcohol use (n=33; 15.0%), a previous history of stroke and transient ischaemic attacks (6.4%), family history (n=12; 5.5%), migraine (n=6;2.8%), pregnancy related (n=5; 2.3%) and numerous cardiac risk factors (0.9-5.5%). The majority suffered arterial infarction; n=216 (99.4%) while n=2 (0.6%) had venous strokes. The predominant stroke subtypes were large artery atherosclerosis (LAA); 29.8% and small vessel occlusion (SVO); 20.2%. LAA and SVO accounted for 37.5% of all stroke subtypes in the ≤36 year age-group. Cardioembolism (15.1%) and stroke of determined aetiology (14.7%) contributed to the other categories of identified stroke subtypes. Mortality on hospital discharge was 3.1% while 65.1% of patients were independent on discharge. Conclusion: This study demonstrated the substantial presence of premature atherosclerosis and conventional risk factors in young ischaemic stroke patients from 8 Asian cities. Venous infarction from cerebral venous thrombosis was rare in this study. Outcome on hospital discharge was poorer compared to Western studies. Detection of vascular risk factors and primary prevention measures should be initiated during late adolescence or early adulthood in urban Asia.

    This cross sectional study aimed to explored the pattern of socio-demographic distribution, to assess the level of KAP of food safety; and the relationship with the level of premise cleanliness in the food courts at Putrajaya. Distribution of food handlers socio-demographic profile was Malaysian (62.0%), male (70.4%), working experienced in food industry (82.0%) and attended food handler training (85.0%). The mean age was 28.7 years and 85.4% having income not less than RM 1,500 monthly. 78.5% of the food handlers at educational level were found as primary/secondary school. 15.0% of the respondents had not attended the food sanitation training. The findings reveal that food handlers’ KAP were high with a mean percentage score more than 79.0%.The majority of the food courts in Putrajaya had consistently moderate level of cleanliness (63.5%) with the mean of 83.03%. Only 27.4% of the food courts were in the level of clean situation (>89% of premise cleanliness score) and 9.1% were not in the clean condition (

    "Urban concentration (or primacy) and inequality (in size distribution of income) are expected to follow bell shaped curves through the development process. Spatial convergence (through investments in transportation etc.) is expected to precede income convergence. Using longitudinal data from six Asian countries (Japan, Taiwan, Malaysia, the Philippines, Sri Lanka and India) this paper shows that (i) the bell shapes for urban concentration and income inequality generally hold, and (ii) the temporal relationship between the curve peaks is determined by geographical factors (for urban concentration); income inequality is seen to be more policy amenable."

    OBJECTIVES: To explore the epidemiological and histopathological patterns of glomerular diseases in Sabah.

    METHODS: A state-wide cross-sectional study was conducted. There were 336 native renal biopsies in 296 eligible patients from 1st January 2013 to 30th June 2016. All patients aged ≥12 years with sufficient sampling (≥8 glomeruli) for histopathological assessment were included. Graft kidney biopsies, protocol-based biopsies and patients with uncertain demographics were excluded. Demographics of patients, clinical data, laboratory parameters prior to biopsy, and histology findings of renal biopsies were collected from local unit database and recorded into a standardised data collection form. Descriptive statistical analyses were employed and factors associated with Lupus nephritis (LN) were explored using logistic regression.

    RESULTS: The mean age during biopsy was 34.53 years (Standard Deviation 0.759). Primary glomerulonephritis (PGN) accounted for 42.6% (126) of all native renal biopsies. The commonest cause of PGN was minimal change disease (38.9%, 49) followed by focal segmental glomerulosclerosis (33.3%, 42) and IgA nephropathy (14.3%, 18). LN is the leading cause for secondary glomerulonephritis (SGN) (87.2%, 136). Younger age (Odds Ratio, OR 0.978; 95% Confidence Interval, 95%CI 0.960, 0.996); female gender (OR 17.53; p<0.001); significant proteinuria (OR 132.0; p<0.001); creatinine level at biopsy (OR 11.26; p=0.004); positive antinuclear antibody (ANA) (OR 46.7; p<0.001); and ANA patterns (OR 8.038; p=0.018) were significant in predicting the odds of having LN.

    CONCLUSION: This is the first epidemiology study of glomerular diseases in Sabah. The predominance of LN suggests lower threshold for renal biopsy in patients with suspected glomerular disorders. We have identified significant predictors for early detection and treatment of LN.

    "This paper examines how and to what extent the three demographic components of urban change, urban reclassification, natural increase and net migration, operated in Malaysia between 1980 and 1991.... Since there is a spatial dimension to urban demographic changes, another emphasis of the paper is to differentiate the areal patterns of such changes. The analysis is conducted at both the national level and sub-national levels." Data are from the Malaysian Department of Statistics. The author finds that "the important role of natural increase in urban population change is remarkable considering that a rapid fertility transition had been unfolding in Malaysia up to the mid-1970s."
