Recent innovations in the treatment of schizophrenia reflect a growing trend towards community-based care. Malaysia had in the past few years attempted to deinstitutionalise mental patients in the mental hospitals. Therefore it is important to conduct research to compare the two groups of schizophrenia patients (community-based patients against chronic hospitalised patients) to ascertain if deinstitutionalisation has been beneficial. The main objective of the study was to compare levels of depression and function in community-based patients against chronic hospitalised patients as depression is prevalent among schizophrenia patients. This study was cross sectional in nature where data was collected from 51 inpatients in Hospital Bahagia Ulu Kinta (HBUK) and 23 community-based patients. Calgary Depression Scale for Schizophrenia (CDSS) and Global Assessment of Functioning scale (GAF) were the assessment tools used. Community-based patients were found to have significantly lower scores in the CDSS scale (1.96) as compared to chronic hospitalised patients (4.04); p < 0.01). They also showed higher functional capability between community-based and hospitalised patients respectively (74.04 vs 57.92) respectively. (p < 0.001). Community services appeared to be more effective than long stay in-patient services in preventing depression and promoting better functional levels.

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.

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.

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.

Trauma Surg Acute Care Open, 2017;2(1):e000070.
PMID: 29766083 DOI: 10.1136/tsaco-2016-000070

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.

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.

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.

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.
Fulltext A rare case of scrotal basal cell carcinoma in the presence of metastatic squamous cell carcinoma of the external auditory meatus and its management strategy

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.

Obesity is a risk factor for chronic diseases which can affect work productivity and physical function of employees
particularly among those in security sector. The study aimed to determine the association between obesity with total
days of sick leave and health related quality of life (HRQoL) among Malay male security officers. A cross-sectional
study was conducted among Malay male security officers working in a Malaysian higher learning institution. Subjects
were evaluated using anthropometric measurements, quality of life and number of sick leave taken within two months
prior to the study. A total of 194 subjects (mean age 40.12 ± 11.41 years) were recruited. A total of 30.4% were obese,
39.7% were pre-obese and only 29.9% had normal body weight or underweight. Central obesity was observed in 57.7%
of them and 87.1% shown excessive body fat percentage. Number of sick leave days was positively correlated with Body
Mass Index (BMI) (r = 0.162, p = 0.024) and waist circumference (r = 0.181, p = 0.012). Score of the general health
component was negatively correlated with BMI (r = -0.161, p = 0.025), waist circumference (r = -0.194, p = 0.007) and
body fat percentage (r = -0.191, p = 0.008). Physical functioning score was lowest in obese subjects than normal and
pre-obese subjects (p = 0.046). Score of the bodily pain component was positively correlated with waist circumference (r
= 0.156, p = 0.030). Obesity is associated with number of sick leave days and quality of life in the studied group. Hence,
body weight of the security staff should be monitored and appropriate intervention should be conducted to improve their
work attendance and quality of life.

A total of 85 food handlers participated in this study to determine the hygienic status of their hands in primary schools located in the state of Selangor (Malaysia). Overall findings revealed that the fecal contamination and personal hygiene of the food handlers were well maintained with the range of mean bacterial counts from 0.18 to 0.47 log10 Colony Forming Units/cm2 during the three intervals of hand swabbing (before, during and after) preparation of ready-to-eat foods. However, the general indication of the microbiological quality (Aerobic Plate Count) was out of the standard (range of mean bacterial counts from 1.39 to 1.56 log10 Colony Forming Units/cm2) based on previous literature. This study highlighted that the food handler’s adherence to Good Manufacturing Practice and Sanitation Standard Operating Procedures was insufficient and suggested that attention should be emphasized on their practices at the intervals of school recess: before, during and after the preparation of ready-to-eat foods. In addition, there is also a need in the implementation of an effective HACCP program in Malaysia school foodservice operations.

Response Surface Methodology (RSM) was used in the study to optimize the production of vanillin from isoeugenol through fermentation by Aspergillus niger I-1472. Three factors were studied which include amount of isoeugenol, resin (Amberlite XAD-4) and Span 80. During fermentation, isoeugenol as substrate were vortexed with Span 80 and added into the culture on Day 4. Resin (Amberlite XAD-4) was added into the medium the following day. The predicted optimum medium combination consisted of 3.61 g/L of isoeugenol, 5.8% (g/ mL) of Amberlite XAD-4 resin and 0.37% of Span 80 with an expected vanillin production of 0.137 g/L. Verification test showed that the model produced similar predicted and experimental values.

This study was conducted to determine and compare the muscle activity during step forward lunge (SFL) and jump forward lunge (JFL) in badminton. Fifteen university badminton players (mean age = 22.07 ± 1.39 years old) were recruited and were assigned to perform SFL and JFL while holding a badminton racquet using their preferred hand. Muscle activation of vastus lateralis (VL), vastus medialis (VM), rectus femoris (RF), biceps femoris (BF), gluteus maximus (GM), medial gastrocnemius (MG), and lateral gastrocnemius (LG) were analysed and compared between SFL and JFL and also between dominant and non-dominant lower limb in each lunge protocol. Results showed for both the dominant and non-dominant lower limb, all the muscle activation was greater during JFL compared to SFL except for the MG muscle. All the muscle activation was also found to be greater in the dominant compared to non-dominant lower limb for both lunge protocols. Overall, findings demonstrated the existence of differences in muscle activation across difference protocols of movement and different site of limbs. This should be taken into consideration for developing training program in order to enhance performance and reduce the risk of injuries.

Staphylococcus aureus is the leading cause for foodborne diseases. Extensive use of antibiotics has led to emergence of antibiotic-resistant S. aureus. Hence, interest on natural plant-based alternative which limits the use of synthetic chemicals is growing. The present work evaluated the antibacterial capacity of garlic, aloe vera, galangal, pineapple peel, neem, papaya leaf, lemongrass, peppermint, nutmeg and clove separately extracted with hexane, ethanol and water to a final concentration of 10% w/v against ampicillin+penicillin-resistant isolates of S. aureus in vitro. Streptomycin was used as a drug control against the resistant isolates; BRS023, BRS068 and DRS072. According to the interpretive standards for inhibition zone diameter provided by the Clinical and Laboratory Standards Institute, isolates BRS068 and DRS072 were considered resistant (≤ 12 mm), and isolate BRS023 was considered intermediate (13-14 mm). Against these isolates, all crude plant extracts exhibited varying degrees of inhibition. However, a coherent trend was observed in the inhibition between resistant and intermediate isolates regardless of plants and solvents used. It was also found that extraction solvent types impacted the resulting antibacterial activity. In terms of positive inhibition, the solvents were ranked in the order of hexane (77%) > water (73%) > ethanol (57%). 10% hexane extract of galangal gave the overall highest inhibition zones (17.8 ± 1.4 mm) closely followed by 10% ethanol extract of nutmeg (16.3 ± 1.1 mm). Further phytochemical analyses of the antibacterial compounds from galangal and nutmeg, and their minimum inhibitory concentration (MIC) are needed. Potential applications of plant-based antibacterial compounds as natural, costeffective and less-toxic food preservatives against drug-resistant foodborne pathogens should be explored.

The primary objectives of this study were to process corncob into corncob powder (CCP)
and to apply CCP in the formulation of instant cereal beverage (ICB) in order to produce
high fibre ICB, and to investigate the physicochemical and sensory properties of the
corncob-based instant cereal beverage. Corncobs were sourced and washed thoroughly
before drying and grinding into CCP. CCP was then imparted into ICB formulation in
three different ratios (10, 20 and 30% w/w) to partially substitute corn flour in the
formulation. All four ICB samples including the commercial counterpart were analysed
for their physicochemical and sensory properties. The incorporation of CCP has affected
the viscosity, colour and sensory attributes significantly of the produced ICB. Higher
contents of CCP in the formulation was found to be responsible for less viscous and
browner effect compared to the commercial ICB samples. Formulation of ICB
incorporated with 30% w/w CCP had the highest mean scores (6.00, p

Many studies on postural photogrammetry had reported various intra-class correlation coefficients (ICC) across postural variable measurements, however no conclusive solution was given. This reliability and cross-sectional study was done in June 2016 at the Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah. A total of 24 male adult subjects with mean age 28.5 years (± 4.8 years), body mass 24.97 kg (± 3.85 kg) and height 166.6 cm (± 6 cm) were evaluated for standing postural photogrammetry. Four sets of manually digitized posture image files (by 4 raters) were measured and statistically analyzed for interrater agreement as well as the influence of image resolution and camera height from the floor on various postural variable measurements. The ICC between 4 raters for all postural variables was excellent (the lowest ICC was 0.940 for Q Angle of the Right Knee measurements). Two-Way ANOVA showed that postural variable measurements were not affected by either image resolution or camera height from the floor. Scrupulous attempts done on standing postural photogrammetry amplified the potential for standing postural evaluation in clinical settings.

The prevalence of pulmonary artery catheter (PAC) entrapment in open-heart surgery is scarce with a prevalence rate of 0.065%. Challenges in managing such cases lie particularly in choosing the modalities (chest roentgenogram, fluoroscopy, and transesophageal echocardiography) to accurately identify the anatomic location and cause of entrapment. In this case, we report a 42-year-old man who underwent mitral valve replacement with PAC entrapment discovered on postoperative day 2 and subsequently underwent retrieval after re-sternotomy. This case also highlights the usefulness of transesophageal echocardiography by the cardiac anesthetist in aiding the surgeons to locate the anatomic location where the catheter was entrapped.

Virtual Reality (VR) is a technology that makes use of computer graphics,
algorithms and special hardware to simulate the real world in real time. There
are four main elements required to make a VR system a success, namely
virtual world, immersion, sensory feedback and interactivity. The virtual
world created must be as real as possible. Users should have a sense of
immersion in the virtual world. Position tracking is usually incorporated into
a VR system for visual, sound and force feedback on the users and the virtual
objects in the VR world must be interact-able with the users. VR has proven
to be effective in training and widely used in many areas, for example medical
surgery, dental treatment, psychology treatment for phobia, engineering
design, maintenance and repair, sports and many more. By implementing VR
technology in training, users are able to reduce the training cost and time. VR
training is also safer for users, as harsh environments can be simulated despite
the environment and/or human factors. On the other hand, the physical
facilities and infrastructures of the track cycling are very costly. In track
cycling, the game field, known as a velodrome, requires a large space of area.
It requires a huge budget and professional manpower to maintain these
facilities. Therefore, the proposed spatial immersive track cycling simulator
is invented to overcome these issues. The aim of this study is to simulate the
velodrome track cycling in VR environment and synchronize with a 6 degreeof-freedom
motion platform. The simulator is aimed to be low cost and
minimal space requirement compared to actual velodrome. A trainee who
undergoes VR track cycling simulator training wears a head-mounted-display (HMD) to visualize the VR environment. An actual bike will be mounted on
the 6-DOF motion platform, which the platform will synchronize with the VR
environment to simulate the track condition for the training purposes. An
encoder is placed at the bicycle wheel to feedback the moving speed and
synchronize the visualize feedback to the HMD.
