    SHAKE Technical Package outlines the policies and interventions in reducing population salt intake which includes five overarching elements needed to create a successful salt reduction programme followed by the five elements of the SHAKE Package for salt reduction that consist of (1) surveillance, (2) harness the industry, (3) adopt the standards for labelling and marketing, (4) knowledge, and (5) environment. The aim for the present work was to critically review the documents related to the dietary sodium reduction strategies in Malaysia as compared to the SHAKE Technical Package. This review involves online and physical document searches of documents related to dietary sodium reduction within the Ministry of Health Malaysia. Visits to each related department via a liaison officer were done for clarification about the documents. Data was sorted according to the SHAKE Framework and a SWOT analysis was done. A total of 32 documents related to salt reduction policies and 15 health education materials were identified. Malaysia’s salt reduction policies comply to four out of five overarching elements of a successful salt reduction program with the presence of political commitment, dedicated programme leadership and governance, partnership with other ministries and stakeholders and integration with iodine deficiency elimination programme. For the SHAKE Package, Malaysia’s policies comply with all the five SHAKE Package elements. However, further investigation revealed that the food products involved in the food reformulation programme were limited. The SWOT analysis revealed that Malaysia has developed a specific plan for a national salt reduction strategy by producing its own Salt Reduction Strategy to Prevent and Control Non-Communicable Diseases for Malaysia Guidelines 2015-2020. Currently, there is no comprehensive database on the salt content of processed foods in Malaysia mainly due to the absence of mandatory labelling for sodium content in processed foods, which is a significant threat to the implementation of salt reduction initiative in the country. Pro-active non-governmental organisations (NGOs) and civil society groups advocating salt reduction in the community is needed to place salt high on the political and developmental agenda Salt reduction strategy as a policy in Malaysia includes almost all recommendations in the SHAKE Framework Malaysia. However, it is still in its early stage.

    β-mangostin were synthesised and characterised. The structure of the
    ligand, β-mangostin was confirmed using NMR and the purity of ligand
    was determined using HPLC. Both Cu(II) and Fe(II) complexes were
    prepared by reaction between the ligand and the acetate of the metals in
    one-step reaction. The synthesised compounds have been characterised
    using UV-Visible, FTIR and CHNS analyser. Ligand and metal complexes
    were tested against bacteria to assess on their antimicrobial properties using
    Minimum Inhibitory Concentrations (MICs) and Minimum Bactericidal
    Concentrations (MBCs) method. The elemental analysis and spectra data
    suggested octahedral geometry for both Cu(II) and Fe(II) complexes. The
    IR spectroscopy revealed that the chelation of Cu2+ and Fe2+ ion occurred
    with hydroxyl and carbonyl group at C9
    and C1 respectively of β-mangostin.
    Both Cu(II) and Fe(II) complexes showed stronger inhibition against
    Pseudomonas aeruginosa, Proteus vulgaris, Klebsiella pneumoniae and
    Salmonella pneumonia at concentration 900 mg/mL and Escherichia coli
    at 450 mg/mL compared to the ligand itself

    Abnormal intraocular pressure (IOP) if left untreated it can lead to glaucoma and permanent vision loss. However, the correlation between IOP and body weight status, sodium intake, and blood pressure (BP) are unclear among adolescents. This cross-sectional study aimed to determine the relationship between body weight status, sodium intake, and BP with IOP among orang Asli adolescents. A total sample of 50 adolescents of Orang Asli aged 13 to 17 participated in this study. Three days' dietary intake was recorded through 24-hour diet recall to determine the sodium intake. The questionnaire was administered to acquire socio-demographic information, and measurements Body Mass Index (BMI) and BP were done according to standard protocols, and IOP was measured using Tonopen. Data obtained involving 40% boys and 60% girls. Two boys (4%) were underweight, 13 boys (26%) and 17 (34%) girls were normal weight, 4 (8%) boys and 11 (22%) girls were overweight, 1 (2%) boy and 2 (4%) girls were obese. Sixty percent of subjects have exceeded the Lowest-Observed-Adverse-Effect-Level (LOAEL) of 2300 mg of sodium intake. Hypertension stage 1 was found higher than hypertension stage 2 in male and female subjects, with 38% of the female have stage 1 hypertension compared to only 14% in male subjects. 98% of subjects have normal IOP and only 2% of subjects have high IOP. There was a significant association between BMI and IOP (p

    The importance of vitamin A and Zinc has been a major concern due to their deficiency among children. This research aimed to investigate the association of vitamin A and zinc intake with visual acuity among Orang Asli children in Semenyih, Selangor. The total subjects involved were 94, consisting of boys, and girls aged 8-12 years old. A food frequency questionnaire (FFQ) was used to determine the level of vitamin A and zinc intake. A Bailey-lovie chart test was used to determine the visual acuity. Vitamin A intake was highest among boys aged 8-9 years old (720 ± 324 mg). The mean intake of zinc, was lowest among boys aged 10-12 years old (4.42 ± 1.00 mg) and highest among girls aged 8-9 years old (5.04 ± 1.14 mg). The prevalence of abnormal visual acuity was 24%, which was equivalent to 23 subjects from the overall sample, consisting of boys and girls with a value of 0.50 Dioptric spherical equivalence (DSE). Findings from the research show that vitamin A and Zinc intake have a significant association with Visual acuity (p

    Introduction: Leprosy is a chronic granulomatous disease which also known as Hansen’s disease caused by Mycobacterium leprae. The social rights and health requirements should not be neglected among the remaining survivors. Although nutritional status and leprosy invasion has been studied in the past, there is still an unclear relationship between these two. The aim of this study was to assess the relationship between nutritional status and disability among the leprosy survivors.
    sampling was conducted at Sungai Buloh, Selangor area from June 2014 to July 2014. The degree of disability was assessed using Barthel’s Index and the nutritional status assessment was assessed using Mini Nutritional Assessment. The data was analysed using SPSS version 20.
    Results: A total of 73 patients were involved in the study (60.3% were male and 89.0% were Chinese). The prevalence of disability was 56.2% (95% CI: 44.5 – 67.8) with walking up-stair s the highest item that need help (50.7%). There were 9.6% malnourished and 49.3% were at risk of malnutrition. There was a negative strong correlation between Nutritional score and the Barthel’s index score (Spearman rho, ρ = -0.714, p < 0.001).
    Conclusions: Measures must be taken to improve their nutritional status in order to increase their ability to be more independent particularly those who are very old. The degree of disability increases with malnutrition.

    Nonsurgical retreatment involves removing mechanical barriers such as gutta-percha to achieve proper cleaning and disinfection. The complexity of the anatomy of molar tooth gives challenge in retreatment procedure. Thus, this study evaluates the amount of residual gutta-percha after retreatment with rotary files (Reciproc Blue®) from each maxillary first molar canal using cone-beam computed tomography (CBCT) and the time required to accomplish it. Nine freshly extracted maxillary molars were instrumented and obturated. Preoperative CBCT was taken, and retreatment was done using Reciproc Blue®. CBCT was taken post retreatment, and the residual volume percentage of gutta-percha from each canal was calculated. The total retreatment time was recorded, and the data were statistically analyzed. The result shows no statistically significant difference in the amount of residual filling material in mesiobuccal, distobuccal, and palatal canal for maxillary first molar and total time used for retreatment with Reciproc Blue® system.

    Gangguan fungsi ereksi adalah salah satu kesan sampingan metadon yang paling lazim. Gangguan ini menjejaskan lebih daripada separuh populasi pesakit metadon dari segi fungsi seksual mereka. Masalah ini dikaitkan dengan penurunan kualiti hidup yang ketara. Gangguan fungsi ereksi boleh menyebabkan masalah yang lebih besar jika tidak dirawat kerana pesakit mungkin memilih untuk menggunakan rawatan sendiri yang berbahaya seperti menyalahgunakan methamphetamine. Penggunaan dadah untuk mengatasi kesan sampingan metadon boleh menyebabkan gangguan penggunaan dadah ganda yang dapat mengganggu rawatan ketagihan dadah. Untuk mengatasi masalah ini, pengamal dan pesakit memainkan peranan yang penting dalam pengurusan gangguan fungsi ereksi. Kesedaran pesakit mengenai gangguan fungsi ereksi dan impaknya serta intervensi aktif oleh doktor untuk mengesan gangguan fungsi ereksi, adalah penting untuk meningkatkan tingkat pengesanan dan pengurusan gangguan fungsi ereksi. Saringan gangguan fungsi ereksi yang kerap dan faktor risikonya akan membantu mengenalpasti pesakit yang menderita gangguan fungsi ereksi. Pelbagai pilihan rawatan seperti rawatan bupropion, trazodone dan banyak lagi tersedia untuk merawat gangguan fungsi ereksi yang akan diterokai lebih lanjut dalam kajian ini.

    Kenaikan segmen ST di elektrod aVR elektrokardiografi di dalam kes diseksi aorta mempunyai risiko kematian yang tinggi. Ia melibatkan diseksi yang berlaku di akar aorta. Kami melaporkan kes pesakit lelaki muda yang menghidap penyakit darah tinggi, yang datang ke Jabatan Kecemasan dengan sakit dada dan sakit di bahagian kaki. Pemeriksaan fizikal pada bahagian bawah kiri anggota adalah konsisten dengan iskemia akut. Elektrokardiogram menunjukkan serangan jantung akut di bahagian elektrod anterolateral, dan kenaikan ST segmen di elektrod aVR. Ekokardiografi menunjukkan akar aorta yang berukuran 4.51 cm dan kehadiran flap intimal, meningkatkan kebarangkalian diseksi pada akar aorta dan arteri koronari. Tomography Computed Angiogram menunjukkan terdapat diseksi aorta dari akar aorta termasuk flap intimal berhampiran permulaan arteri koronari kiri, hingga ke arteri iliac utama ke arteri iliac kiri. Malangnya, pesakit memilih untuk tidak menjalani pembedahan dan akhirnya meninggal dunia selepas 48 jam di masukkan ke wad. Kes ini menjelaskan bahawa, dalam kes diseksi aorta yang hadir dengan sindrom 'malperfusion', kenaikan segmen ST pada elektrod aVR akan meningkatkan kebarangkalian terjadinya diseksi aorta yang teruk melibatkan akar aorta dan juga arteri koronari, yang menjadikan prognosis pesakit lebih teruk.

    Seeking treatment is a vital when an individual falls sick. However, some may not do so perhaps they are ashamed to admitting having shameful diseases or unable to seek and reach help. Negative perception of the community on sensitive diseases like AIDS or sexual transmitted disease (STD) may drive the patients away from seeking treatment and suffer alone. In Islam we are thought to always have positive perceptions (husnu dzan) towards any issues in daily life especially when dealing with human interaction by avoiding bad perceptions (su’u dzan). Thus, this study aims to identify the factors affecting treatment seeking patterns among public in three selected areas in Kuantan, and to explore factors affecting people not able or avoid seeking treatment, also to determine the relationship between treatment seeking patterns and the influential factors ie distance, accessibility and behaviour; attitude to health, healthcare and self-perception. A cross sectional survey was carried out at Taman Gelora, Teluk Cempedak and Terminal Makmur, Kuantan, Pahang. Convenient sampling method was used in this study. 201 respondents participated and answered a semi-structured questionnaire modified from Adamson. Results showed that the data was normally distributed, 50.2% respondents were male and 58.7% the total respondents were between 16-26 years old. Majority of the respondents had neutral attitude to health and healthcare, and to self-perception; 94.03% and 73.63% respectively. From the results, there were significant association between distance and accessibility, and monthly income, plus between self-perception and demographic data (p

    Introduction: Scarcity of fresh water is currently blighting the population of the least developed countries around the world. According to WHO, waterborne diseases accounts for 4.1% of total disability adjusted life years (DALYs) with a mortality rate of 1.8 million per year. Numerous pathogens and chemicals may be the potential sources of water contamination that leads to waterborne diseases in humans. Some pathogens are only active and express disease whilst within the host. The aim of this article is to identify the cause of water-borne diseases and how to control it from the Islamic perspective. Material and Methods: In this review we had compiled the latest scientific findings related to waterborne diseases and integrated them with Islamic approach of cleanliness. There are many Hadithsof the Prophet (peace be upon him) (PBUH) regarding methods of cleanliness with scientific background to control waterborne diseases. Water pollution may be a natural process, men made, intentional or accidental. More often than not, man are infected after accidently consuming or coming in contact with contaminated water Results: Scientific literature search reveals that individual hygiene and sanitation is the most prominent way to prevent waterborne diseases. In Islam, Prophet Muhammad (PBUH) puts a great emphasize on purification in terms of personal cleanliness and made it mandatory to follow rule to remain pure both physically and spiritually. Conclusions: Sunnaticapproaches of cleanliness may hinder waterborne disease.

    Bakery products become a regular food in most part of the world and are essential commodities today. There is a high potential for business growth in selling bakery products. In the business world, Small-Medium Enterprises (SMEs) are primarily engaged in the bakery business, but cannot compete with the branded bakery Industry. The SMEs in Malaysia are striving hard to achieve growth in the business of bakery products. The present case study deals with the issues faced by SMEs and provided some valid recommendations to resolve the existing problems in the bakery business. The case analysis and its findings reveal that SMEs have unstructured marketing strategies and needs enhancements in the areas of packaging, value add to the bakery products, focus on promotion and appropriate advertising strategies. Further, the analysis reveals that more coverage of selling points for bakery products, the increased number of distribution centers and proper incentives to the agents may definitely improve the marketing of bakery products.

    The purpose of this study was to investigate the functional properties (thickness; water vapor
    permeability (WVP); film microstructure, tensile strength (TS) and biodegradability) of
    carboxymethyl cellulose (CMC)/gelatin (gel)/chitosan (chi) biocomposite film as influenced
    by different drying temperature (25 and 60 °C). Seven formulations (CMC/gel/chi) prepared
    were control (100/0/0), formulations A (80/20/0), B (80/0/20), C (80/10/10), D (60/20/20),
    E (60/30/10), and F (60/10/30). Different drying temperature resulted in different time taken
    for the film to dry. Results revealed that formulation F was optimal due to its high tensile
    strength and low WVP rate which support its biodegradability for both drying conditions. FTIR
    assay revealed a strong carboxyl group for CMC, which contributed to high biodegradability
    results (85.3 vs. 85.50%) for room vs. oven dried specimens, respectively. Such desirable
    characteristics demonstrated that film F holds remarkable potential as edible films material
    with enhanced positive impacts on the environment and community.

    Kesatuan Ekonomi ASEAN (AEC) merupakan realisasi matlamat akhir integrasi ekonomi yang diasaskan pada pemusatan keinginan negaranegara ASEAN untuk meluaskan intergrasi ekonomi melalui inisiatif baru dan sedia ada dalam kerangka masa yang telah ditetapkan. Dalam merealisasikan salah satu tindakan AEC yang telah dikenal pasti iaitu memperkasakan perlindungan pengguna ASEAN, pengharmonian undang-undang kontrak pengguna dilihat sebagai salah satu agenda penting ASEAN. Dengan berobjektifkan pengharmonian undang-undang kontrak ASEAN yang mengkhusus kepada penggunaan terma tidak adil dalam pasaran pengguna seterusnya mencadangkan ASEAN Model Law on Unfair Terms in Consumer Contracts, makalah ini mengadoptasi metodologi analisis kandungan berteraskan literatur undang-undang primer dan sekunder. Mengguna pakai undang-undang kes dan perundangan di enam negara ASEAN terpilih iaitu Malaysia, Singapura, Indonesia, Thailand, Filipina dan Brunei, penyelidikan ini mendapati wujud persamaan dalam mekanisme yang digunakan di negara-negara ASEAN ini dalam menangani permasalahan penggunaan terma tidak adil dalam kontrak pengguna. Namun walaupun perundangan dilihat sebagai mekanisme yang mampu menangani permasalahan ini, wujud perbezaan pendekatan dalam perundangan yang diadaptasi oleh negara-negara ASEAN tersebut. Penggunaan perundangan berorientasikan perlindungan pengguna bagi mengawal penggunaan terma tidak adil dalam kontrak pengguna jelas kelihatan di Malaysia, Singapura, Indonesia, Thailand dan Filipina. Penggunaan perundangan kontrak yang mengkhusus kepada terma tidak adil sebagai instrumen kawalan pula kelihatan di Singapura, Thailand dan Brunei. Dalam aspek ini, keunikan Singapura dan Thailand yang menangani permasalahan terma tidak adil dalam kontrak pengguna dengan mengadakan perlindungan melalui dua jenis perundangan yang berbeza menampakkan korpus perlindungan pengguna yang lebih mapan. Pendekatan yang berbeza yang diamalkan di beberapa negara ASEAN terpilih ini memperlihatkan satu korpus perlindungan pengguna yang unik dalam aspek kontrak pengguna tidak adil.

    The aim of this work is to study the effect of hydrocolloids (guar gum, xanthan gum and carboxymethyl cellulose (CMC) on the physical properties and sensory evaluation of ice cream produced in order to investigate the potential of applying fermented glutinous rice (tapai pulut) as a value-added ingredient. The addition of 25% fermented glutinous rice was the most reliable amount to enhance the physical and sensory properties of ice cream when incorporating hydrocolloids. The addition of hydrocolloids significantly (p < 0.05) increased the pH, firmness, overrun, and melting rate of fermented glutinous rice ice cream. The addition of guar gum scored the highest firmness value (5403 g) followed by CMC (4630 g) and xanthan gum (3481g). Fermented glutinous rice ice cream with xanthan gum added, induced a noticeable change in overrun value (62%) while the addition of CMC decreased the melting rate compared to the control. The FTIR spectrum of fermented glutinous rice ice cream with different hydrocolloids containing carboxyl, amide and carbonyl group was appeared at 3362-3379 cm-1 , 1639-1640 cm-1 and 1026-1064 cm-1, respectively. In conclusion, the addition of xanthan gum presented great potential to improve the quality of fermented glutinous rice ice cream produced in terms of its firmness, overrun and melting rate.

    Although the Ministry of Health Malaysia has been encouraging the practice of Traditional and Complementary Medicine (T&CM)1, 2 , 3, 4 but patients/clients has not been able to apply it for their need of medical treatments and sometimes it leads to negative outcomes due to lack of knowledge on T&CM and its safe applications5,6’ 7,8 Most of the western-trained physicians are ignorant of risk and benefits of T&CM9,10,11 . This study was aimed to determine the gap between knowledge regarding T&CM and perception on education in T&CM among the medical staffs in five selected hospitals in Malaysia. A cross-sectional survey was done at five public hospitals among medical staff in Malaysia by using quantitative methods. A total of 477 medical staffs were involved in this study. The study showed that the overall knowledge of T&CM among the medical staffs were poor (61.2%). Having good knowledge regarding T&CM were significantly higher in Hospital Duchess of Kent (52%, p=0.001), among the non-Malays (44%, p=0.047) and pharmacists (47.2%, p=0.030). Positive perception on health education in T&CM among medical staffs were high (85.3%) especially among females (88.1%, p=0.002) and pharmacists (93.7%, p< 0.001). The use of T&CM among the general population is relatively high in Malaysia and many patients increasingly seek the information on T&CM therapies from medical staffs. Knowledge regarding T&CM was poor in this study because most of the medical staffs have not been exposed to T&CM education. This interesting scenario between poor knowledge and high positive perception on health education in T&CM shows the demand of urgent intervention in educating the medical staffs. We recommend that medical staffs must have some basic education and knowledge about T&CM before they could offer advice to their patients. Doctors are of the utmost important in this regard because they play a very important role in patient care. Providing T&CM education to medical staff may help to integrate T&CM into the mainstream medicine.

    Human breast milk microbiota is essential for infant immune system development, maturation and
    protection against infection. However, there is scarce information on the fluid’s microbiological
    composition from Malaysia. The objective of the study was to isolate, identify and characterise commensal
    bacterial population present in human breast milk from Malaysia. One hundred bacteria were isolated
    from the human breast milk of healthy lactating women (n=30). After preliminary screening, 20 isolates
    were characterised using both phenotypic and molecular techniques. The results indicated that most
    frequently identified bacteria in this study were E. faecalis and S. hominis. These organisms alongside E.
    cloacae were all metabolised D-Maltose, Sucrose, D-Turanose, α-D-Glucose, D-Fructose, D-Mannose,
    D-Galactose, D-sorbitol and D-Mannitol and were able to grow at pH 5 and 6, 1% sodium lactate, 1%,
    2% and 8% NaCl. BLAST showed over 99% similarity to those deposited in Genbank. Phylogeneticrelatedness
    was depicted using neighbour-joining method and had two clades with 100% bootstrap. These
    findings provided insight into the nature, characteristics and also phylogenetic-relatedness of bacteria
    present in human milk from Malaysia. Isolation and identification of commensal bacteria from human
    milk are considered the first step for future studies on the benefit of these organisms towards human health.

    There are three types of papilloma which arises from the Schneiderian membrane namely inverted, fungiform and oncocytic. Oncocytic papilloma is the rarest type and occurs predominantly in the older age group. Clinically, its behaviour is similar to inverted papilloma in having both local recurrence and associated malignancy. We report a rare case of oncocytic papilloma arising from the maxillary sinus, extending into the nasal cavity and nasopharynx, in a 78-year-old lady. Despite the longstanding history there was no evidence of associated malignancy in this lesion. An endoscopic medial maxillectomy was successfully utilized for approach and complete tumour excision. In conclusion, oncocytic papilloma should be considered as a differential diagnosis in patients presenting with unilateral polypoid nasal lesions especially in the elderly. In addition, endoscopic medial maxillectomy can provide an adequate approach for complete tumour removal.

    Covalently cross-linked nanogels were prepared via irradiation of inverse micelles that had been preparedfrom radiation crosslinkable polymer, water, oil and surfactant. A mixture of polymer, water, heptane andsodium dioctyl sulfosuccinate (AOT) at certain compositions forms inverse micelles with the size rangingfrom 2 to 8 nm. The hydrophilic head of the surfactant facilitates encapsulation of water soluble polymer.If the entrapped polymer is radiation crosslinkable, it is expected that upon irradiation, polymerizationshall take place in such small and confined space, leading to formation of nano-sized polymeric gel.Meanwhile, emulsion at 2 nm size was chosen for gamma irradiation process. The formation of thenano-sized discreet gel using irradiation of inverse micelles technique was proven at a dose as low as 5kGy to obtain nanogel sized ~ 95 nm.

    A Boolean permutation is called nonlinear if it has at least one nonlinear component function. All nonlinear Boolean permutations and their complements are called non-affine Boolean permutations. Any non-affine Boolean permutation is a potential candidate for bijective S-Box of block ciphers. In this paper, we find the number of n-variable non-affine Boolean permutations up to multiplicative n and show a simple method of construction of non-affine Boolean permutations. However, non-affinity property is not sufficient for S-Boxes. Nonlinearity is one of the basic properties of an S-Box. The nonlinearity of Boolean permutation is a distance between set of all non-constant linear combinations of component functions and set of all non-affine Boolean functions. The cryptographically strong S-Boxes have high nonlinearity. In this paper, we show a method of construction of 8-variable highly nonlinear Boolean permutations. Our construction is based on analytically design (8, 1), (8, 2), and (8, 3) highly nonlinear vectorial balanced functions and random permutation for other component functions.
