    The bioaccumulation and bioavailability of polycyclic aromatic hydrocarbons (PAHs) were characterized in sediment and Paphia undulata (short-neck clam) from six mudflat areas in the west coasts of Peninsular Malaysia. The concentrations of total PAHs varied from 357.1 to 6257.1 and 179.9 ± 7.6 to 1657.5 ± 53.9 ng g -1 dry weight in sediment and short-neck clam samples, respectively. PAHs can be classified as moderate to very high level of pollution in sediments and moderate to high level of pollution in short-neck clams. The diagnostic ratios of individual PAHs and principal component analysis indicate both petrogenic and pyrogenic sources with significant dominance of pyrogenic source. The first PAHs biota-sediment accumulation factors and relative biota-sediment accumulation factors data for short-neck clam were obtained in this study, indicating a preferential accumulation of lower molecular weight PAHs. Evaluation of PAH levels in sediments and short-neck clams indicates that short-neck clam could be introduced as a good biomonitor in mudflats. The results also demonstrated that under environmental conditions, the sedimentary load of hydrocarbons appears to be one of the factors controlling their bioavailability to biota.

    Blastocystis sp., an intestinal organism is known to cause diarrhea with metronidazole regarded as the first line of treatment despite reports of its resistance. The conflicting reports of variation in drug treatment have been ascribed to subtype differences. The present study evaluated in vitro responses due to metronidazole on ST3 isolated from three symptomatic and asymptomatic patients, respectively. Symptomatic isolates were obtained from clinical patients who showed symptoms such as diarrhea and abdominal bloating. Asymptomatic isolates from a stool survey carried out in a rural area. These patients had no other pathogens other than Blastocystis. Ultrastructural studies using transmission electron microscopy (TEM) and scanning electron microscopy (SEM) revealed drug-treated ST3 from symptomatic patients were irregular and amoebic with surface showing high-convoluted folding when treated with metronidazole. These organisms had higher number of mitochondrion-like organelle (MLO) with prominent cristae. However, the drug-treated ST3 from asymptomatic persons remained spherical in shape. Asymptomatic ST3 showed increase in the size of its central body with the MLO located at the periphery.

    INTRODUCTION: Little is known regarding the educational needs and perspectives of people living with Parkinson's disease (PD), particularly in Asia.

    OBJECTIVE: To assess knowledge and perceptions regarding PD in a large multiethnic urban Asian cohort of patients and caregivers.

    METHODS: We conducted a survey at a university hospital neurology clinic, using a novel Knowledge and Perception of Parkinson's Disease Questionnaire (KPPDQ).

    RESULTS: The KPPDQ had satisfactory psychometric properties among patients and caregivers. Five hundred subjects were recruited with a 97% response rate (211 patients, 273 caregivers). Non-motor symptoms such as urinary problems, visual hallucinations and pain were relatively poorly recognized. Many (≈ 50-80%) respondents incorrectly believed that all PD patients experience tremor, that PD is usually familial, and that there is a cure for PD. About one-half perceived PD to be caused by something the patient had done in the past, and that PD medications were likely to cause internal organ damage. Issues of stigma/shame were relevant to one-third of patients, and 70% of patients perceived themselves to be a burden to others. Two-thirds of participants felt that PD imposed a heavy financial toll. Participants were about equally divided as to whether they would consider treatment with deep brain stimulation, tube feeding or invasive ventilation. Over three-quarters of patients expressed a preference to die at home.

    CONCLUSIONS: Important knowledge gaps, misperceptions and perspectives on PD were identified, highlighting the need for further efforts to raise awareness and provide accurate information regarding PD, and to address patient's and caregivers' needs and preferences.

    INTRODUCTION: Next-generation sequencing (NGS) diagnostics have shown clinical utility in predicting survival benefits in patients with certain cancer types who are undergoing targeted drug therapies. Currently, there are no guidelines or recommendations for the use of NGS in patients with metastatic cancer from an Asian perspective. In this article, we present the Asia-Pacific Oncology Drug Development Consortium (APODDC) recommendations for the clinical use of NGS in metastatic cancers.

    METHODS: The APODDC set up a group of experts in the field of clinical cancer genomics to (i) understand the current NGS landscape for metastatic cancers in the Asia-Pacific (APAC) region; (ii) discuss key challenges in the adoption of NGS testing in clinical practice; and (iii) adapt/modify the European Society for Medical Oncology guidelines for local use. Nine cancer types [breast cancer (BC), gastric cancer (GC), nasopharyngeal cancer (NPC), ovarian cancer (OC), prostate cancer, lung cancer, and colorectal cancer (CRC) as well as cholangiocarcinoma and hepatocellular carcinoma (HCC)] were identified, and the applicability of NGS was evaluated in daily practice and/or clinical research. Asian ethnicity, accessibility of NGS testing, reimbursement, and socioeconomic and local practice characteristics were taken into consideration.

    RESULTS: The APODDC recommends NGS testing in metastatic non-small-cell lung cancer (NSCLC). Routine NGS testing is not recommended in metastatic BC, GC, and NPC as well as cholangiocarcinoma and HCC. The group suggested that patients with epithelial OC may be offered germline and/or somatic genetic testing for BReast CAncer gene 1 (BRCA1), BRCA2, and other OC susceptibility genes. Access to poly (ADP-ribose) polymerase inhibitors is required for NGS to be of clinical utility in prostate cancer. Allele-specific PCR or a small-panel multiplex-gene NGS was suggested to identify key alterations in CRC.

    CONCLUSION: This document offers practical guidance on the clinical utility of NGS in specific cancer indications from an Asian perspective.

    Honeycomb with good mechanical properties and low density are the top priorities in
    material selection. Therefore, the facesheet thickness is a factor that contributes to it
    as it made up most of the weight in the structure. Appropriate thickness can optimize
    the mechanical performance. However, the sandwich composite may associate to high
    density if the facesheet is of high thickness yet deteriorate the mechanical properties
    as an overall. As the facesheet is attached to the sandwich structure via matrix, the
    peeling properties for various facesheet thickness is investigated. The facesheet
    thickness in terms of one to five layers are glued to the rubber wood core. The
    structures are tested for its peeling strength under vertical 90° test according to the
    ASTM standard. The optimal number of facesheet with good peeling strength is
    discussed

    Introduction The risk factors associated with mental health among adolescents are usually
    described by researchers at an individual level. Neighbourhood factors and
    health have opened a new insight into the field of epidemiology. The aim of
    this study was to assess the reliability and validity of a newly developed
    Neighbourhood Factors on Mental Health Questionnaire among Malaysian
    adolescents.

    Methods A cross-sectional study was conducted in four secondary schools in Kuala
    Lumpur, Malaysia using a newly developed questionnaire which comprised
    of two main domains and seven items. Exploratory factor analysis and
    Cronbach‟s alpha were used to measure the instrument‟s construct validity
    and reliability.

    Results A total of 106 adolescents participated in this research. The majority of
    adolescents were 13 years old (40.6%), female (55.7%), Malays (68.9%),
    have parents who only studied until secondary school (66.0%) and lived in
    flats (32.1%). Bartlett‟s Test of Sphericity was significant (Chi-square =

    To study the wound healing efficacy of breadfruit starch hydrolysate, an in vitro wound scratch assay was conducted, in which the migration rate of wounded NIH 3T3 fibroblasts was determined. Wounds treated with lower dextrose equivalent (DE), (DE 10-14) starch hydrolysate were found capable to improve the wound healing of NIH 3T3 fibroblast cell with the percentage of wound closure improvement of 77%, respectively when compared with higher DE range (DE 15-19 and DE 20-24). The findings obtained in the BrdU uptake and MTT viability assays confirmed the wound healing properties of breadfruit starch hydrolysate as the starch hydrolysate-treated wounded NIH 3T3 fibroblasts were able to proliferate well and no cytotoxicity was observed. Together, these findings indicated that the newly developed breadfruit starch hydrolysate performed better than commercial (COM) starch hydrolysate of the same DE ranges. In conclusion, breadfruit starch hydrolysate had better functional properties than did starch hydrolysates derived from other sources and that they could play a beneficial role in wound healing applications.

    Introduction: Home visits are complex processes for clients and occupational therapists. Despite the benefits of home
    visits, the numbers of home visits being conducted are decreasing in international settings due to service constraints
    or client reluctance. Published international studies may not be applicable to Malaysia due to cultural and geodemographic
    differences relating to the home context. This study aimed to explore the experience of occupational
    therapists in Malaysia in conducting home visits. Materials and Methods: A focus group discussion was conducted
    with seven occupational therapists in one teaching hospital in Kuala Lumpur. The group session was audio-recorded,
    transcribed, summarised and analysed using thematic analysis. Results: Themes developed were: i) client factors
    inhibiting effective service provision, ii) uninformed policies and guidelines, and iii) professional identity and
    growth. Conclusions: Our study has revealed major challenges for Malaysian occupational therapists with regards
    to conducting home visits. Future studies should now evaluate factors underlying reluctance to participate in home
    visits and effective strategies to overcome these difficulties.

    Bivalves are known for their ability to accumulate contaminants such as heavy metals. This allows them to be widely used as bioindicator in monitoring of heavy metals in the marine environment. This study was conducted to determine the levels of heavy metals, namely Copper (Cu), Chromium (Cr), Nickel (Ni), Lead (Pb), Arsenic (As), Zinc (Zn) and Manganese (Mn) in marsh clams (Polymesoda expansa) and green mussels (Perna viridis) along the northwest coast of Sabah (Marudu Bay, Ambong Bay, and Mengkabong). The results showed that As (5.1 to 12.8 μg/g) and Mn (33.5 to 116.0 μg/g) concentrations in both marsh clams and green mussels collected from all the sampling stations along the northwest coast of Sabah were much higher than the permissible limit set by the Ministry of Health Malaysia and FAO/ WHO. Similarly, concentration of Zn (265.8 to 535.9 μg/g) in marsh clams from all the sampling areas and that of Cr (53.9 μg/g) in green mussel collected from Marudu Bay were also much higher than the permissible limits. The data also suggested that marsh clams accumulated higher Pb and Zn, whereas green mussels tend to contain higher concentrations of Cr, Cu and Ni. Since bivalves are an important protein source for the local population, a regular monitoring of all edible bivalve species should be conducted so that consumers can be advised about the toxicological and health risks due to consumption of bivalves.

    It has been recognized extensively that studies of pharmacogenetics provide massive examples of causal relationship between genotypes and drug effectiveness to account for interindividual phenotypic variations in drug therapy. In most cases, cytochrome P450 (CYP) polymorphisms are one of the major variables that affecting those drug plasma concentration, drug detoxification and drug activation in humans. Thus, understanding of CYP polymorphisms can be crucially valuable in order to allow early and more accurate drug dosage prediction and improve the drug response accordingly. Despite the high level of homologous amino acid sequences, CYP2C9 and CYP2C19 genes are among the most important CYP genes which metabolize a wide range of clinically therapeutic drugs. Several critical reviews have been published relating to the aforementioned genes. However, this minireview aims to systematically merge reported studies on the SNPs frequencies of both genes concentrating only on Malaysian population. It is hoped that, the minireview can be an opener for new opportunities to reevaluate the evidence on the prevalence of CYP2C genes as a potential genetic factor influencing a particular drug efficacy and safety among Malaysian. Such evaluation can be developed to the next level of early prediction of better and specific drug treatment, thereby improving the drug response while helping the government in minimising the drug expenditures.

    In the perspective of recent bauxite mining in Malaysia, this review aims to identify the potential
    environmental and health impacts on miners and surrounding communities. The environmental issues of
    bauxite mining include, air, water and soil pollution due to bauxite dust; leaching of bauxite into water
    sources resulting in reduced soil fertility as well as affecting agricultural food products and aquatic life.
    Bauxite occupational exposure affects the health of miners, and has negative consequences on the health of
    surrounding communities, such as increased respiratory symptoms, contamination of drinking water, other
    potential health risks from ingestion of bauxite and heavy metals, including noise-induced hearing loss and
    mental stress. This review discusses the processes of bauxite mining, its constituents and residual trace
    elements, and their impact on the environment and health of exposed workers and communities. It also
    explores the Malaysian legal requirements and standards of occupational exposure to bauxite.

    Background of Study: Mental Health Knowledge Schedule (MAKS) is an instrument to assess knowledge about mental health issues commonly used in English-speaking countries.
    Objectives: The present study translated the MAKS into Malay language (MAKS-M) and investigate its reliability in the Malaysian context among secondary school teachers.
    Methods: A total of 77 secondary school teachers answered the back-translated MAKS-M before and after attending a mental health literacy program. Cronbach’s alpha and
    Lin’s concordance statistics of the data were computed.
    Results: Test-retest reliability was below the satisfactory level. Specifically, internal consistency was low for Time 1 but improvement was observed in Time 2.
    Conclusion: The findings suggest that fundamental knowledge about mental health may be required for individuals to understand the items. Recommendations were provided for future studies to explore the usability of the MAKS-M.

    Background: Trauma mortality due to exsanguination is the second most common cause of death. The objective of this study is to investigate the predictors for early death from exsanguination.

    Methods: A prognostic study was done to identify predictors of early mortality due to exsanguination. Data were extracted from our Trauma Surgery Registry database of Sultanah Aminah Hospital, Johor Bahru, Malaysia. All patients who were treated from May 1, 2011 to April 31, 2014 by the trauma team were included. Adult trauma patients included from the Trauma Surgery Registry were divided into two groups for analysis: early death from exsanguination and death from non-exsanguination/survivors. Univariate and multivariate analysis was performed to look for significant predictors of death from exsanguination. Variables analyzed were demography, mechanism of injury, organ injury scale, physiological parameters (systolic blood pressure (SBP), respiratory rate, heart rate, temperature), Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), New Injury Severity Score (NISS), Trauma and Injury Severity Score (TRISS) and cause of death.

    Results: A total of 2208 patients with an average age of 36 (±16) years were included. Blunt trauma was the majority with 90.5%, followed by penetrating injuries (9.2%). The overall mortality is 239 out of 2208 (10.8%). Seventy-eight patients (32.6%) died due to central nervous system injury, 69 due to sepsis (28.9%) and 58 due to exsanguination (24.3%). After multivariate analysis, age (OR 1.026 (1.009 to 1.044), p=0.002), SBP (OR 0.985 (0.975 to 0.995), p=0.003) and temperature (OR 0.203 (0.076 to 0.543), p=0.001) were found to be the significant physiological parameters. Intra-abdominal injury and NISS were significant anatomic mortality predictors from exsanguination (p<0.001). Patients with intra-abdominal injury had four times higher risk of mortality from exsanguination (OR 3.948 (2.331 to 6.686), p<0.001).

    Discussion: In a Malaysian trauma center, age, SBP, core body temperature, intra-abdominal injury and NISS were significant predictors of early death from exsanguination.

    Level of evidence: II.

    Glaucoma is a chronic disease that could affect the quality of life and is a potential stressor for patients. Visual field assessment is important in monitoring disease progression among glaucoma patients. Stress could influence the performance of patients in visual field test that may affect the reliability of the test. Our objective in this study was to determine the association between stress score using Depression, Anxiety and Stress Scale (DASS) questionnaire and reliability indices of Humphrey visual field analysis (HFA). A total of 155 primary and secondary glaucoma patients were recruited in the study. Face to face interview using stress component of DASS questionnaire was conducted after automated HFA test. Reliability indices; i.e. fixation loss, false positive, and false negative error, were used to determine the accuracy of HFA result. Only 12 patients (7.7%) were found to have elevated stress score. No significant correlation was found between DASS stress score and the reliability indices of HFA. There was 0.2 folds (95% confidence interval (CI) [-2.35, -0.06], p = 0.039) reduction of fixation loss for every number of HFA done. For every one year increase in age, there was 0.2 folds (95% CI [-0.38, -0.07], p = 0.006) reduction in false positive error in HFA.
    Minimal stress may not affect the reliability of HFA assessment. Minimising stress among glaucoma patients is important not only for assessment of visual field but also for improvement of quality of life.

    The new innovative of technology by (GIS) Geographic Information System, (LIS) Land
    Information System and (CIS) Cadastral Information System has been playing a leading
    role in the development of cadastral and land administration in this study area. The
    Customary ways and approach to the land titling and registration in the time past has
    resulted in the delay in the processes of obtaining title to the land. Land administration
    system in Nigeria includes the processes of land registration, cadastral mapping, land
    valuation and land inventory. Most of developing nation particularly Nigeria is faced
    with the problem of poor land administration and management. Technology is
    paramount in acquiring a proper technological development in land administration.
    This study tried to encourage land title registration by providing web technologies that
    are faster and suitable with a low rate and minimum delay. The need to develop a
    dynamic web for the processes in the land registration arises from the dynamic
    relationship to the land of the people. The delay in time and process of land registration
    couple with the exploitation in land related activities has called for the urgent
    intervention of all the stakeholders in land administration. PHP programming language
    was used as a server side scripting languages together with MyAdmin SQL, a website
    was developed for the processes involved in the land registration having examined the
    fastest way to solve the problem. A robust dynamic database that is reliable and easy
    to use was also developed which is capable of accommodating several numbers of
    applicants. The applicants, monitoring agency and the government have the advantage
    of checking all the processes on line without any contact with the officers working on
    the certificate.

    One of the prime inspirations for this work emerge from the need to deal with our
    common assets (the Land). To build up a formal approach that can be utilized to
    address the issues emerges from a mind boggling circumstance in land
    administration. The capacity to track the progressions as it is connected to land
    everywhere throughout the year. A considerable lot of the land exchanges are as yet
    in light of 2D ideal models that have frustrated fast advancement in thickly urban
    condition. The consideration of 3D enhanced the functionalities of different models.
    Be that as it may, the dynamic idea of the land has an imperative part in the
    advancement of the land administration framework. One of the significant reason the
    expansion in intricacy in land utilize required that Land Administration Domain Model
    (LADM) concept in land administration has an enhanced limit is to deal with the
    current 2D and 3D. The need to talk about time dimension emerges from the way
    that individuals relationship to the land has an exceptionally powerful nature, all the
    LADM packages has time (Temporal) components. LADM completely bolster forming
    (historical information) as all classes inherit from VersionObject, and all LA_RRR
    object have the quality TimeSpace. 2D/3D space and time incorporation is not
    profoundly integrated into a 3D/4D spatiotemporal portrayal. The preparatory test
    case in this study affirmed the conceivable outcomes of having a move or
    development (with time) of characteristic limits from their underlying positions. Thus,
    the dynamic idea of the land in connection to man, the benefits of this model to the
    land proprietors, land merchants, and the administration can't be over stressed. This
    study tries to clarify the current 2D/3D approach and broke down preparatory
    requirements for 4D with a specific end goal to see the estimation of the approach.
    The primary future research exertion focuses on melding on the most proficient
    method to coordinate the model completely into Country profile in the study area.

    Basal cell carcinoma (BCC) of the scrotum is uncommon and its pathogenesis is not well understood. The clinical behaviour of scrotal BCC is thought to be more aggressive and has a higher metastatic potential than BCC of other regions. The mainstay of treatment for localized scrotal BCC is wide local excision, while metastatic disease may need systemic chemotherapy for palliative control. A rare clinical scenario of scrotal BCC presenting concurrently with another metastatic cancer has never been reported. The present case illustrates the diagnostic challenge and management dilemma due to simultaneous presentation of scrotal BCC and metastatic squamous cell carcinoma (SCC). A 70-year-old man complained of a non-healing scrotal ulcer while he was being investigated for metastatic squamous cell carcinoma (SCC) of the external auditory meatus. The scrotal lesion was initially thought to be metastatic SCC. It was later confirmed to be BCC with biopsy and histopathological examination. He underwent surgical resection of the scrotal BCC for local control followed by palliative chemotherapy with cisplatin and radiotherapy for lymph node metastases. He remained well and did not have any local recurrence following 6 months after palliative treatment. Surgery coupled with palliative chemoradiation can offer good quality of life for patients with scrotal BCC and concurrent metastatic SCC.
