PMID: 25426599 DOI: 10.1111/j.2041-1626.2011.00048.x

This communication analyzed research publications in dentistry in the Institute of Scientific Information Web of Science databases of 10 dental faculties in the Association of South-East Asian Nations (ASEAN) from 2000 to 2009. The term used for the "all-document types" search was "Faculty of Dentistry/College of Dentistry." Abstracts presented at regional meetings were also included in the analysis. The Times Higher Education System QS World University Rankings showed that universities in the region fare poorly in world university rankings. Only the National University of Singapore and Nanyang Technological University appeared in the top 100 in 2009; 19 universities in the region, including Indonesia, Malaysia, the Philippines, Singapore, and Thailand, appeared in the top 500. Data from the databases showed that research publications by dental institutes in the region fall short of their Asian counterparts. Singapore and Thailand are the most active in dental research of the ASEAN countries.

Fulltext Mixed biopolymer systems based on starch

Abd Elgadir M, Akanda MJ, Ferdosh S, Mehrnoush A, Karim AA, Noda T, et al.

Molecules, 2012 Jan 09;17(1):584-97.
PMID: 22231495 DOI: 10.3390/molecules17010584

A binary mixture of starch-starch or starch with other biopolymers such as protein and non-starch polysaccharides could provide a new approach in producing starch-based food products. In the context of food processing, a specific adjustment in the rheological properties plays an important role in regulating production processing and optimizing the applicability, stability, and sensory of the final food products. This review examines various biopolymer mixtures based on starch and the influence of their interaction on physicochemical and rheological properties of the starch-based foods. It is evident that the physicochemical and rheological characteristics of the biopolymers mixture are highly dependent on the type of starch and other biopolymers that make them up mixing ratios, mixing procedure and presence of other food ingredients in the mixture. Understanding these properties will lead to improve the formulation of starch-based foods and minimize the need to resort to chemically modified starch.

Hii CL, Law CL, Cloke M, Sharif S

J Sci Food Agric, 2011 Jan 30;91(2):239-46.
PMID: 20872824 DOI: 10.1002/jsfa.4176

Various studies have been conducted in the past to improve the quality of Malaysian cocoa beans. However, the processing methods still remain crude and lack technological advancement. In terms of drying, no previous study has attempted to apply advanced drying technology to improve bean quality. This paper presents the first attempt to improve the quality of cocoa beans through heat pump drying using constant air (28.6 and 40.4 °C) and stepwise (step-up 30.7-43.6-56.9 °C and step-down 54.9-43.9 °C) drying profiles. Comparison was made against hot air drying at 55.9 °C.

Review of technologies for oil and gas produced water treatment

Fakhru'l-Razi A, Pendashteh A, Abdullah LC, Biak DR, Madaeni SS, Abidin ZZ

J Hazard Mater, 2009 Oct 30;170(2-3):530-51.
PMID: 19505758 DOI: 10.1016/j.jhazmat.2009.05.044

Produced water is the largest waste stream generated in oil and gas industries. It is a mixture of different organic and inorganic compounds. Due to the increasing volume of waste all over the world in the current decade, the outcome and effect of discharging produced water on the environment has lately become a significant issue of environmental concern. Produced water is conventionally treated through different physical, chemical, and biological methods. In offshore platforms because of space constraints, compact physical and chemical systems are used. However, current technologies cannot remove small-suspended oil particles and dissolved elements. Besides, many chemical treatments, whose initial and/or running cost are high and produce hazardous sludge. In onshore facilities, biological pretreatment of oily wastewater can be a cost-effective and environmental friendly method. As high salt concentration and variations of influent characteristics have direct influence on the turbidity of the effluent, it is appropriate to incorporate a physical treatment, e.g., membrane to refine the final effluent. For these reasons, major research efforts in the future could focus on the optimization of current technologies and use of combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.

Properties of high-oleic palm oils derived by fractional crystallization

Ramli MR, Siew WL, Cheah KY

J Food Sci, 2008 Apr;73(3):C140-5.
PMID: 18387090 DOI: 10.1111/j.1750-3841.2007.00657.x

High-oleic palm oil (HOPO) with an oleic acid content of 59.0% and an iodine value (IV) of 78.2 was crystallized in a 200-kg De Smet crystallizer with a predetermined cooling program and appropriate agitation. The slurry was then fractionated by means of dry fractionation at 4, 8, 10, 12, and 15 degrees C. The oil and the fractionated products were subjected to physical and chemical analyses, including fatty acid composition, triacylglycerol and diacylglycerol composition, solid fat content, cloud point, slip melting point, and cold stability test. Fractionation at 15 degrees C resulted in the highest olein yield but with minimal oleic acid content. Due to the enhanced unsaturation of the oil, fractionation at relatively lower crystallization temperature showed a considerable effect on fatty acid composition as well as triacylglycerol and diacylglycerol composition of liquid fractions compared to higher crystallization temperature. The olein and stearin fractionated at 4 degrees C had the best cold stability at 0 degrees C and sharper melting profile, respectively.

Aroma precursors and methylpyrazines in underfermented cocoa beans induced by endogenous carboxypeptidase

Jinap S, Ikrawan Y, Bakar J, Saari N, Lioe HN

J Food Sci, 2008 Sep;73(7):H141-7.
PMID: 18803708 DOI: 10.1111/j.1750-3841.2008.00858.x

Cocoa-specific aroma precursors and methylpyrazines in underfermented cocoa beans obtained from fermentation induced by indigenous carboxypeptidase have been investigated. Fermentation conditions and cocoa bean components were analyzed during 0 to 3 d of fermentation. Underfermented cocoa beans were characterized as having hydrophilic peptides and free hydrophobic amino acids much higher than unfermented ones. These 2 key components of cocoa aroma precursors may be produced from the breakdown of proteins and polypeptides by endogenous carboxypeptidase during the fermentation process. The enzyme was activated during fermentation. Polypeptides of 47, 31, and 19 kDa were observed in the samples throughout the 3-d fermentation period; however, only the first 2 polypeptides were remarkably reduced during fermentation. Since the 1st day of fermentation, underfermented cocoa beans contained methylpyrazines, a dominant group of cocoa-specific aroma. This might be due to microbial activities during fermentation, observed through a decrease of pH value and an increase of temperature of cocoa beans. The concentration of tetramethylpyrazines was significantly increased during the 3 d of fermentation. This may increase the cocoa-specific flavor to the beans.

Sharing Malaysian experience with the development of biotechnology-derived food crops

Abu Bakar UK, Pillai V, Hashim M, Daud HM

Food Nutr Bull, 2005 Dec;26(4):432-5.
PMID: 16465992

Biotechnology-derived food crops are currently being developed in Malaysia mainly for disease resistance and improved post harvest quality. The modern biotechnology approach is adopted because of its potential to overcome constraints faced by conventional breeding techniques. Research on the development of biotechnology-derived papaya, pineapple, chili, passion fruit, and citrus is currently under way. Biotechnology-derived papaya developed for resistance to papaya ringspot virus (PRSV) and improved postharvest qualities is at the field evaluation stage. Pineapple developed for resistance to fruit black heart disorder is also being evaluated for proof-of-concept. Other biotechnology-derived food crops are at early stages of gene cloning and transformation. Activities and products involving biotechnology-derived crops will be fully regulated in the near future under the Malaysian Biosafety Law. At present they are governed only by guidelines formulated by the Genetic Modification Advisory Committee (GMAC), Malaysia. Commercialization of biotechnology-derived crops involves steps that require GMAC approval for all field evaluations and food-safety assessments before the products are placed on the market. Public acceptance of the biotechnology product is another important factor for successful commercialization. Understanding of biotechnology is generally low among Malaysians, which may lead to low acceptance of biotechnology-derived products. Initiatives are being taken by local organizations to improve public awareness and acceptance of biotechnology. Future research on plant biotechnology will focus on the development of nutritionally enhanced biotechnology-derived food crops that can provide more benefits to consumers.

Ismail R

Asia Pac J Clin Nutr, 2005;14(4):414-9.
PMID: 16326649

Several million tones of palm oil and palm olein are used annually in the world for frying. This paper will discuss their frying performances in three major applications - industrial production of potato chips/crisps, industrial production of pre-fried frozen French fries and in fast food outlets. In the first study, about four tones of potato chips were continuously fried 8 hours a day and five days a week. The palm olein used (with proper management) performed well and was still in excellent condition and usable at the end of the trial. This was reflected in its low free fatty acid (FFA) content of around 0.23%, peroxide value of 4 meq/kg, anisidine value of 16, low polar and polymer contents of 10% and 2%, respectively, induction period (OSI) of 21 hours and high content of tocopehrols and tocotrienols of 530 ppm even after >1900 hours. In the second study in which an average 12 tones pre-fried frozen French fries were continuously fried a day for 5 days a week, palm oil performed excellently as reflected by its low FFA of 0.34%, food oil sensor reading of 1.1, low polar and polymer contents of 17% and 2.8%, respectively, over the 12 days of trial. In the third study in which palm shortening, palm oil and palm olein were simultaneously used to intermittently fry chicken parts in the laboratory simulating the conditions in fast food outlets, the three frying oils also performed very satisfactorily as reflected by their reasonably low FFA of <1%, smoke points of >180 degrees C, and polar and polymer contents of <25% and <6%, respectively, after 5 days of consecutive frying. All the quality indicators did not exceed the maximum discard points for frying oils/fats in the three applications, while the fried food product was well accepted by the in-house train sensory panel using a-nine point hedonic score.

Mohd-Tahir NA, Paraidathathu T, Li SC

SAGE Open Med, 2015;3:2050312115596864.
PMID: 26770795 DOI: 10.1177/2050312115596864

Malaysia inherits a highly subsidized tax-based public healthcare system complemented by a fee-for-service private sector. Population health in Malaysia has considerably improved since independence using a relatively small amount of gross domestic product (~4%). Brain drain of highly specialized personnel, growth in healthcare spending, demographic and disease pattern changes and increase in patients' demands and expectations towards better medical care are exerting pressure on the sustainability of the system to continuously provide efficient and effective services at relatively low cost. Malaysia has adopted and implemented some of the quality use of medicine concepts such as National Essential Medicine List, health technology assessment and promotion of generic medicines in their health policy, but so far the results may not be optimal. Activities to further promote these strategies are needed for successful implementation to achieve more positive and sustained beneficial outcomes. Better strategic planning, management and collaboration between various stakeholders, considering the needs and barriers of the strategies, are important to ensure effective implementation of the strategies. More emphasis should be placed upon more equitable and rational distribution of healthcare resources to cater for rapid urbanization. Additionally, a sustainable health financing structure that is more progressive and does not encourage moral hazard should be established. In conclusion, Malaysia has achieved good outcomes in population health with relatively low financial inputs since independence. However, changes in the overall environment have created issues which would threaten the long-term viability of the healthcare system if not tackled properly. The numbers of internationally trialled strategies could be used to deal with these challenges. In addition, coordinated implementation of these strategies and effective engagement and communication between various stakeholders are necessary to further strengthen the Malaysian healthcare system effectively.

Fulltext Factors affecting risk tolerance among small-scale seasonal commodity farmers and strategies for its improvement

Agussabti A, Romano R, Rahmaddiansyah R, Isa RM

Heliyon, 2020 Dec;6(12):e05847.
PMID: 33426340 DOI: 10.1016/j.heliyon.2020.e05847

In developing countries, farming businesses are dominated by small-scale farmers with limited resources. Such farmers are subjected to high risks, influencing the success rate of their agricultural endeavors. This study, conducted in Aceh Province, Indonesia, measured the risk tolerance among six groups of farmers with businesses based on the following seasonal commodities: paddy, corn, soy, chili, potato, and tomato. A total of 360 respondents were surveyed and 54 key respondents interviewed. A Likert scale was used to assess the risk tolerance levels of the farmers, and ordinal regression analysis to analyze the factors influencing risk tolerance. Paddy, chili, and potato farmers had a relatively high tolerance to farming risks, whereas corn and tomato farmers showed a moderate tolerance. Soy farmers were classified into the low risk tolerance category. Ordinal analysis indicated that the risk tolerance of farmers in each commodity group was influenced by specific factors. Overall, it was found that the farmers' attitudes to risk tolerance were significantly affected by the following factors: experience, education, farming income, capital, land status, and land size. An intervention strategy including improvements in the curriculum, actors, network, scope of clusters, and technology are among the strategies required to positively improve farmers' perceptions and increase their tolerance to farming risks.

Fulltext Quality of Service Class Identifier (QCI) radio resource allocation algorithm for LTE downlink

Mamman M, Hanapi ZM, Abdullah A, Muhammed A

PLoS One, 2019;14(1):e0210310.
PMID: 30682038 DOI: 10.1371/journal.pone.0210310

The increasing demand for network applications, such as teleconferencing, multimedia messaging and mobile TV, which have diverse requirements, has resulted in the introduction of Long Term Evolution (LTE) by the Third Generation Partnership Project (3GPP). LTE networks implement resource allocation algorithms to distribute radio resource to satisfy the bandwidth and delay requirements of users. However, the scheduling algorithm problem of distributing radio resources to users is not well defined in the LTE standard and thus considerably affects transmission order. Furthermore, the existing radio resource algorithm suffers from performance degradation under prioritised conditions because of the minimum data rate used to determine the transmission order. In this work, a novel downlink resource allocation algorithm that uses quality of service (QoS) requirements and channel conditions to address performance degradation is proposed. The new algorithm is formulated as an optimisation problem where network resources are allocated according to users' priority, whereas the scheduling algorithm decides on the basis of users' channel status to satisfy the demands of QoS. Simulation is used to evaluate the performance of the proposed algorithm, and results demonstrate that it performs better than do all other algorithms according to the measured metrics.

Mohamed SH, Hossain MS, Mohamad Kassim MH, Ahmad MI, Omar FM, Balakrishnan V, et al.

Polymers (Basel), 2021 Feb 19;13(4).
PMID: 33669623 DOI: 10.3390/polym13040626

There is an interest in the sustainable utilization of waste cotton cloths because of their enormous volume of generation and high cellulose content. Waste cotton cloths generated are disposed of in a landfill, which causes environmental pollution and leads to the waste of useful resources. In the present study, cellulose nanocrystals (CNCs) were isolated from waste cotton cloths collected from a landfill. The waste cotton cloths collected from the landfill were sterilized and cleaned using supercritical CO2 (scCO2) technology. The cellulose was extracted from scCO2-treated waste cotton cloths using alkaline pulping and bleaching processes. Subsequently, the CNCs were isolated using the H2SO4 hydrolysis of cellulose. The isolated CNCs were analyzed to determine the morphological, chemical, thermal, and physical properties with various analytical methods, including attenuated total reflection-Fourier transform-infrared spectroscopy (ATR-FTIR), field-emission scanning electron microscopy (FE-SEM), energy-filtered transmission electron microscopy (EF-TEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The results showed that the isolated CNCs had a needle-like structure with a length and diameter of 10-30 and 2-6 nm, respectively, and an aspect ratio of 5-15, respectively. Additionally, the isolated CNCs had a high crystallinity index with a good thermal stability. The findings of the present study revealed the potential of recycling waste cotton cloths to produce a value-added product.

Acceptance towards social network information system for earlier detection of Influenza outbreak

Sulaiman MH, Aizuddin AN, Hod R, Puteh SEW

Med J Malaysia, 2021 03;76(2):145-150.
PMID: 33742620

INTRODUCTION: Influenza outbreak causes high economic burden to Malaysia and other countries in South East Asia. Scientists have found a relatively new way to detect influenza outbreaks early thus reducing the burden of disease by early intervention. This new technology is a social network information system which uses Facebook or Twitter data to detect potential influenza cases. Such system is good to be developed by the Malaysian government as it can detect influenza outbreaks three weeks earlier than the normal pathway. However, to implement this we require good evidence that the development will be accepted by potential users.
OBJECTIVE: This study was looking at the acceptance towards using social network information system among public health workers.
MATERIALS AND METHOD: This study was done on 205 Malaysian One Health University Network (MyOHUN) members through email and physical survey.
RESULTS: Results show that 62.4% public health workers accepted the use technology. The acceptance was shown to be associated with performance expectancy (p<0.05). However, unlike the very famous Unified Theory of Acceptance and Use of Technology (UTAUT) model, the acceptance of social network information system was not associated with effort expectancy, social factors, facilitating conditions and socio-demographic factors. Therefore, it is suggested that social network information system be developed by the authorities in Malaysia, and be developed in a way that the system could strongly increase performance in detection of outbreak earlier than the current normal pathways. As such the system to be accepted and used, it must be sensitive, specific and be able to detect influenza outbreak early CONCLUSION: The development of social network information system is feasible as it is highly accepted and it's potential to improve early detection of influenza outbreak.

Fulltext Current Update of Collagen Nanomaterials-Fabrication, Characterisation and Its Applications: A Review

Lo S, Fauzi MB

Pharmaceutics, 2021 Feb 28;13(3).
PMID: 33670973 DOI: 10.3390/pharmaceutics13030316

Tissue engineering technology is a promising alternative approach for improvement in health management. Biomaterials play a major role, acting as a provisional bioscaffold for tissue repair and regeneration. Collagen a widely studied natural component largely present in the extracellular matrix (ECM) of the human body. It provides mechanical stability with suitable elasticity and strength to various tissues, including skin, bone, tendon, cornea and others. Even though exogenous collagen is commonly used in bioscaffolds, largely in the medical and pharmaceutical fields, nano collagen is a relatively new material involved in nanotechnology with a plethora of unexplored potential. Nano collagen is a form of collagen reduced to a nanoparticulate size, which has its advantages over the common three-dimensional (3D) collagen design, primarily due to its nano-size contributing to a higher surface area-to-volume ratio, aiding in withstanding large loads with minimal tension. It can be produced through different approaches including the electrospinning technique to produce nano collagen fibres resembling natural ECM. Nano collagen can be applied in various medical fields involving bioscaffold insertion or fillers for wound healing improvement; skin, bone, vascular grafting, nerve tissue and articular cartilage regeneration as well as aiding in drug delivery and incorporation for cosmetic purposes.

Geriatrics (Basel), 2021 Mar 22;6(1).
PMID: 33810155 DOI: 10.3390/geriatrics6010031

Social isolation, magnified by the restriction of movement order during the COVID-19 pandemic, may lead to negative psychosocial health impacts among community-dwelling older adults. We, therefore, aimed to evaluate recruitment rates, data collection, and group exercises conducted through virtual technology among individuals aged 60 years and over in Malaysia. Participants were recruited from the Promoting Independence in Seniors with Arthritis (PISA) pilot cohort through social media messaging. A four-week course of virtual group exercise was offered. Anxiety and depression were assessed with the Hospital Anxiety and Depression Scale (HADS) during the last attended follow-up of the cohort study (pre-pandemic), pre-intervention, and post-intervention. Exercise adherence was recorded using diaries with daily entries and attendance to the virtual group exercise sessions were also captured electronically daily. The outcomes of interest were changes in anxiety and depression scores from baseline to pre-intervention (pandemic-related) and post-intervention (virtual exercise related). Forty-three individuals were recruited. A significant increase in anxiety scores from baseline to pre-intervention was observed. Comparisons using repeated-measures analysis of variance between those who attendance ≥14 and <14 group exercise sessions revealed no between-within subject differences in depression scores. There was a 23% dropout rate in the post intervention survey and 60.5% of diaries were returned. Virtual group exercises could be conducted among older adults residing in a middle-income country, though recruitment would have been limited to those with internet access.

Disabil Rehabil Assist Technol, 2020 Jul 09.
PMID: 32643468 DOI: 10.1080/17483107.2020.1785565

PURPOSE: Orientation and Mobility (O&M) professionals teach people with low vision or blindness to use specialist assistive technologies to support confident travel, but many O&M clients now prefer a smartphone. This study aimed to investigate what technology O&M professionals in Australia and Malaysia have, use, like, and want to support their client work, to inform the development of O&M technologies and build capacity in the international O&M profession.
MATERIALS AND METHODS: A technology survey was completed by professionals (n = 36) attending O&M workshops in Malaysia. A revised survey was completed online by O&M specialists (n = 31) primarily in Australia. Qualitative data about technology use came from conferences, workshops and interviews with O&M professionals. Descriptive statistics were analysed together with free-text data.
RESULTS: Limited awareness of apps used by clients, unaffordability of devices, and inadequate technology training discouraged many O&M professionals from employing existing technologies in client programmes or for broader professional purposes. Professionals needed to learn smartphone accessibility features and travel-related apps, and ways to use technology during O&M client programmes, initial professional training, ongoing professional development and research.
CONCLUSIONS: Smartphones are now integral to travel with low vision or blindness and early-adopter O&M clients are the travel tech-experts. O&M professionals need better initial training and then regular upskilling in mainstream O&M technologies to expand clients' travel choices. COVID-19 has created an imperative for technology laggards to upskill for O&M tele-practice. O&M technology could support comprehensive O&M specialist training and practice in Malaysia, to better serve O&M clients with complex needs.Implications for rehabilitationMost orientation and mobility (O&M) clients are travelling with a smartphone, so O&M specialists need to be abreast of mainstream technologies, accessibility features and apps used by clients for orientation, mobility, visual efficiency and social engagement.O&M specialists who are technology laggards need human-guided support to develop confidence in using travel technologies, and O&M clients are the experts. COVID-19 has created an imperative to learn skills for O&M tele-practice.Affordability is a significant barrier to O&M professionals and clients accessing specialist travel technologies in Malaysia, and to O&M professionals upgrading technology in Australia.Comprehensive training for O&M specialists is needed in Malaysia to meet the travel needs of clients with low vision or blindness who also have physical, cognitive, sensory or mental health complications.

Ngatiman M, Jami MS, Abu Bakar MR, Subramaniam V, Loh SK

Heliyon, 2021 Jan;7(1):e05931.
PMID: 33490684 DOI: 10.1016/j.heliyon.2021.e05931

The formation of struvite crystals or magnesium ammonium phosphate (MgNH4PO4) in palm oil mill effluent (POME) occurs as early as in the secondary stage of POME treatment system. Its growth continues in the subsequent tertiary treatment which reduces piping diameter, thus affecting POME treatment efficiency. Hypothesis. The beneficial use of the crystal is the motivation. This occurrence is rarely reported in scientific articles despite being a common problem faced by palm oil millers. The aim of this study is to characterize struvite crystals found in an anaerobic digester of a POME treatment facility in terms of their physical and chemical aspects. The compositions, morphology and properties of these crystals were determined via energy dispersive spectroscopy (EDS), elemental analysis, scanning electron microscopy (SEM) and x-ray diffraction (XRD). Solubility tests were carried out to establish solubility curve for struvite from POME. Finally, crystal growth experiment was done applying reaction crystallization method to demonstrate struvite precipitation from POME. Results showed that high phosphorous (P) (24.85 wt%) and magnesium (Mg) (21.33 wt%) content was found in the struvite sample. Elemental analysis detected carbon (C), hydrogen (H), nitrogen (N) and sulfur (S) below 4 wt%. The crystals analysed by XRD in this study were confirmed as struvite with 94.8% struvite mineral detected from its total volume. Having an orthorhombic crystal system, struvite crystals from POME recorded an average density of 1.701 g cm-3. Solubility curve of struvite from POME was established with maximum solubility of 275.6 mg L-1 at pH 3 and temperature 40 °C. Minimum solubility of 123.6 mg L-1 was recorded at pH 7 and temperature 25 °C. Crystal growth experiment utilizing POME as the source medium managed to achieve 67% reduction in phosphorous content. This study concluded that there is a potential of harnessing valuable nutrients from POME in the form of struvite. Struvite precipitation technology can be adapted in the management of POME in order to achieve maximum utilization of the nutrients that are still abundant in POME. At the same time maximization of nutrient extractions from POME will also reduce pollutants loading in the final discharge.

Objective: The present study aimed to assess the knowledge, attitude, and practice (KAP) of 3rd- and 4th-year medical, dental, and pharmacy students about hepatitis B (HB) infection at a private medical university, Malaysia.
Methods: A cross-sectional, questionnaire-based study was conducted among 482 medical, dental, and pharmacy students of 3rd- and 4th-year degree program of Asian Institute of Medicine, Science and Technology University to assess their KAP about HB infection using 34 prevalidated questions by convenient sampling method. A questionnaire was administered to the students, and their responses were measured at "yes" and "no" scale. Students' responses were entered in SPSS version 22, and quantitative analysis was performed using descriptive statistics and nonparametric tests at P < 0.05.
Findings: The medical, dental, and pharmacy students had good knowledge and practice with positive attitude about HB infection. Mann-Whitney U-test determined a significant difference in knowledge (P < 0.001) and practice (P < 0.001) scores between medical and pharmacy, attitude (P < 0.001) scores between medical and dental, and attitude (P < 0.001) and practice (P < 0.001) scores between pharmacy and dental students. Students' age was correlated with their attitude, practice, and KAP scores and family income with their knowledge, attitude, practice, and KAP scores.
Conclusion: Although students' knowledge and practice were good with positive attitude, all the students did not participate in health education program, screening, and vaccination of hepatitis B virus (HBV) infection which makes them more vulnerable to occupational HBV infection. Hence, it is recommended to organize a regular health education program for the students on screening and vaccination against HBV to prevent its infection.

Introduction: Nursing is a regulated profession. Hence, the global commitment for nurses to maintain standards of practice is vital to deliver safe and competent care. Written policies will eliminate uncertainty, ambiguity, and legal issues. For this study, it focused on the importance of the nursing students to understand and practice the regulation on patient’s confidentiality in healthcare setting with the usage of technology such as social media. There is a case like nursing student infringe the privacy of patients with the information they posted on social media, such as posting a patient’s photos or videos without valid consent. Methods: This study is a quantitative, cross-sectional survey de- sign. The respondents were selected as convenience sampling of 120 nursing students from the Faculty of Medicine and Health Sciences, Universiti Malaysia Sabah (FMHS, UMS). Results: There are 7.4% nursing students intention- ally posted in social media, 18.0% maybe and 73.8% unintentionally. And for their guilty feeling after committing confidentially policy breach on patient, there are 8.2% said NO, 32.8% said MAYBE and 59% said YES. Overall, the nursing students are aware of the patient’s confidentiality but there is still a leakage in practicing full nursing standards and regulation. Further study recommended to explore more on this issue. Conclusion: As a conclusion, this study is relevant to conduct among the nursing students to gain their understanding regarding the responsibilities as a future nurse in maintaining the patient’s confidentiality as one of the most important nursing practices to ensure quality of care and continuation of professional service of nursing profession.
