    Many of our chronic kidney disease (CKD) patients venture into complementary and alternative medicine (CAM) to seek a cure for the disease beyond conventional management. The objective of this study was to determine the prevalence and pattern of CAM usage; and its association with the progression of CKD in our population. This was a cross-sectional survey recruited CKD patients from Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Data was collected via interview using questionnaires which explore the demographics, type and pattern of CAM use. Patients’ comorbidities and serum creatinine were extracted from the medical notes to assess the association between progression of CKD and usage of CAM. Chi-square, Independent Samples t-test, Mann-Whitney U test and logistic regression were used to evaluate for an association. Three hundred and seventy two eligible patients were recruited. The prevalence of CAM use was 29% in the past year. Younger age, higher education and higher income level were associated with significantly more usage of CAM. Natural products were the commonest type of CAM used (86.1%). The belief in the effectiveness of CAM was the main reason for its uptake and about 57.8% revealed their practice to their physician. We found that the use of CAM in Malaysian CKD patients did not influence the progression of the disease.

    The objective of this study is to examine the impact of the casemix reimbursement on the hospital revenue at three selected hospitals (Type B, C and D) reimbursed using 602 groups from 14,749 cases. The results of the study showed that the hospitals received 32.4% higher income when reimbursed with Indonesia Case Bases Groups (INA-CBG) as compared to fee-for-service. Type D hospitals is the biggest gainer with 81.0% increased in income followed by Type B hospital that obtained 34.7% higher revenue. In conclusion, the use of INA-CBG as a prospective payment method has benefitted the hospitals by the increase in the revenues. It is hope that additional resources gained in this programme will allow the hospitals to provide optimum care to the population. It is recommended that the JKA management will use the INA-CBG casemix data to monitor the performance of the hospitals to ensure that quality and efficiency of the services provided to the population is continuously maintained.

    The fast-growing urbanization has contributed to the construction sector be- coming one of the major sectors traded in the world stock market. In general, non- stationarity is highly related to most of the stock market price pattern. Even though stationarity transformation is a common approach, yet this may prompt to originality loss of the data. Hence, the non-transformation technique using a generalized dynamic principal component (GDPC) were considered for this study. Comparison of GDPC was performed with two transformed principal component techniques. This is pertinent as to observe a larger perspective of both techniques. Thus, the latest weekly two-years observations of nine constructions stock market price from seven different countries were applied. The data was tested for stationarity before performing the analysis. As a re- sult, the mean squared error in the non-transformed technique shows eight lowest values. Similarly, eight construction stock market prices had the highest percentage of explained variance. In conclusion, a non-transformed technique can also present a better result outcome without the stationarity transformation.

    Posterior Polymorphous Dystrophy (PPD) is a rare, innocuous and asymptomatic condition in which corneal endothelial cells display characteristics similar to epithelium. It is often bilateral and frequently asymmetric. We report a case of a 10-year-old girl with a family history of glaucoma who presented with right eye blurring of vision since few years. She had frequent spectacle-prescription changing due to unimproved visual acuity. Cycloplegic refraction revealed high astigmatism and moderate amblyopia over the right eye. Her best corrected vision was 6/9 for the right and left eyes. Slit-lamp examination showed a vesicular-like lesion at the periphery of corneal endothelial layers in both eyes. Endothelial cell density was much reduced on the right eye compared to the left, with more severe astigmatism. Other ocular examinations were unremarkable. Patient was instructed to patch her better left eye periodically. Although patients with Posterior Polymorphous Dystrophy (PPD) present at the age of adulthood, the age at diagnosis is highly variable. It is rare and inherited through an autosomal dominant pattern. PPD may rarely lead to astigmatism, by which was present in the patient due to the features of non-keratoconic and keratoconic cornea on the right and left eye, respectively. Endothelial cell counts were reduced more on the right eye compared to the left, which later may worsen her visual acuity thus indicating corneal transplant in the future. Patient also had a strong family history of glaucoma. Hence, screening of associated disease of corneal endothelial dystrophy in the family may be necessary.

    Research has shown that smoking has bad implications on smokers and society as a whole. For that
    matter, the Ministry of Health Malaysia (MOHM) have taken various initiatives through information
    technology and social media to educate the public and students about the negative effects of smoking.
    The objective of this study is to identify the level of awareness among students on factors which lead to
    smoking behaviour and the negative effects it has on society. This study was conducted on 228
    students at the Faculty of Quranic and Sunnah Studies, Islamic Science University of Malaysia. The
    research is quantitative in nature using questionnaire method. The quantitative data were then analysed
    descriptively in Statistical Package for Social Science (SPSS) to obtain the frequency and percentage.
    The finding of the study shows that the level of students’ awareness on factors leading to smoking
    habit is at a satisfactory level. The students are aware that peers are the main contributing factor
    towards smoking habit. The level of awareness on the harmful effects of smoking is also at a
    satisfactory level. The students’ awareness is influenced by their field of study which is Islamic studies
    as well as their modest purchasing power considering their average family income range from RM1000
    to RM3000. The conclusion of the study is the importance to educate students on the harmful effects of
    smoking, as well as to maintain the level of awareness among them.

    The cyber world is actually an easy medium which does not need complicated procedures in order to
    publish ones literary works. This has been the reason on why the young authors choose it as the best
    medium to create more literary works actively. The works of the young authors will be published in the
    cyber world especially in their own personal websites. However, this also has caused misunderstanding
    between the scholars about the aesthetical and the quality that have always been focused on literary
    works. Therefore, this study will find out and analyse the aesthetical value through the thoughts that are
    found in cyber novel Kasih Darmia by Naniey TJ based on the application of Intergrated Aesthetic
    theory. Cyber novel Kasih Darmia is the first cyber literary work of Naniey TJ which was written
    somewhere in November 2011 in her personal blogsite. The study uses the Intergrated Aesthetic which
    is introduced by Abdul Halim Ali based on the concept of beauty which is divided by the beauty of
    thoughts and the religious messages from Al-Quran as the original text that represents the real beauty
    and reflects the manifestation of literary text. Analysing the thoughts in cyber novel Kasih Darmia shows that the inside beauty actually answers the aesthetical problems in the literary works in the cyber
    world.

    MyJurnal
    Introduction: Children spend most of the time indoors and make them easily exposed to indoor air contaminants. Exposure to poor indoor air quality has led to various health problem especially, respiratory-related illness. This study is intended to determine the relationship between indoor air pollutants exposure and the airway inflammation among children aged 5 to 6 years old in selected preschools from mid-2015 until mid-2016. Methods: Four hours of indoor air quality assessment had been conducted at six preschools in Puchong district (urban area) and six preschools in Hulu Langat district (suburban area) of Selangor. The respiratory inflammation among 120 healthy preschool chil- dren had been assessed using non-invasive biomarker of Fractional Exhale Nitric Oxide (FeNO). Meanwhile, respi- ratory symptoms and information on possible residential air pollutant exposures were obtained from a standardized questionnaire. Results: The indoor air quality measurement demonstrated significant high concentration air pollut- ants (PM0.1, PM2.5, PM10, VOCs) at the preschools in the urban as compared to preschools in the suburban area(p < 0.05). Besides, PM2.5 was found to be significantly associated with respiratory inflammation (FeNO value) measured (p

    MyJurnal
    Gelatin has been frequently used in tissue engineering scaffold due to its favorable biological properties in wound healing enhancement. Genipin, a natural compound derived from Gardenia plants, was shown to be effective in improving physicochemical characteristics of the gelatin scaffold. This systematic review reported the utility of genipin as a crosslinker in gelatin scaffold fabrication. Two electronic databases, namely Scopus and MEDLINE via Ebcoshost were searched for publication between January 1999 and December 2018, using the keywords ‘gelatin’ and ‘genipin’. Articles published in English, reporting the utility of genipin in the fabrication of gelatin sponge were included. The keywords search yielded 830 articles, in which 14 articles were selected and examined in this review. The result of the search provided input in terms of the optimum concentration, crosslinking temperature, and fabrication method of genipin to be used. From the literature, it was found that 0.5% is the optimum genipin concentration and 25˚C is the optimum crosslinking temperature. The result also revealed a gap in the knowledge regarding genipin crosslinker and justifies the need to create awareness of the utility of genipin as a gelatin scaffold crosslinker. The current review provides an extensive overview on the current knowledge on genipin crosslinking and be a guide to an optimal fabrication of the genipin-crosslinked gelatin scaffold.

    Shah S, Abbas G, Riaz N, Anees Ur Rehman, Hanif M, Rasool MF
    Expert Rev Pharmacoecon Outcomes Res, 2020 Aug;20(4):343-354.
    PMID: 32530725 DOI: 10.1080/14737167.2020.1782196
    BACKGROUND: Communicable diseases such as AIDS/HIV, dengue fever, and malaria have a great burden and subsequent economic loss in the Asian region. The purpose of this article is to review the widespread burden of communicable diseases and related health-care burden for the patient in Asia and the Pacific.

    AREAS COVERED: In Central Asia, the number of new AIDS cases increased by 29%. It is more endemic in the poor population with variations in the cost of illness. Dengue is prevalent in more than 100 countries, including the Asia-Pacific region. In Southeast Asia, the annual economic burden of dengue fever was between $ 610 and $ 1,384 million, with a per capita cost of $ 1.06 to $ 2.41. Globally, 2.9 billion people are at risk of developing malaria, 90% of whom are residents of the Asia and Pacific region. The annual per capita cost of malaria control ranged from $ 0.11 to $ 39.06 and for elimination from $ 0.18 to $ 27.

    EXPERT OPINION: The cost of AIDS, dengue, and malaria varies from country to country due to different health-care systems. The literature review has shown that the cost of dengue disease and malaria is poorly documented.

    ACS Omega, 2021 Feb 02;6(4):2707-2716.
    PMID: 33553888 DOI: 10.1021/acsomega.0c04897
    Oil and grease remain the dominant contaminants in the palm oil mill effluent (POME) despite the conventional treatment of POME. The removal of residual oil from palm oil-water mixture (POME model) using the progressive freezing process was investigated. An optimization technique called response surface methodology (RSM) with the design of rotatable central composite design was applied to figure out the optimum experimental variables generated by Design-Expert software (version 6.0.4. Stat-Ease, trial version). Besides, RSM also helps to investigate the interactive effects among the independent variables compared to one factor at a time. The variables involved are coolant temperature, XA (4-12 °C), freezing time, XB (20-60 min), and circulation flow, XC (200-600 rpm). The statistical analysis showed that a two-factor interaction model was developed using the obtained experimental data with a coefficient of determination (R2) value of 0.9582. From the RSM-generated model, the optimum conditions for extraction of oil from the POME model were a coolant temperature of 6 °C in 50 min freezing time with a circulation flowrate of 500 rpm. The validation of the model showed that the predicted oil yield and experimental oil yield were 92.56 and 93.20%, respectively.
  12. Fulltext A review of pharmacist-led interventions on diabetes outcomes: an observational analysis to explore diabetes care opportunities for pharmacists
    Iqbal MZ, Khan AH, Iqbal MS, Syed Sulaiman SA
    J Pharm Bioallied Sci, 2019 10 18;11(4):299-309.
    PMID: 31619911 DOI: 10.4103/jpbs.JPBS_138_19
    A strict and adherence treatment is required by the patient with diabetes mellitus and it demands a proper self-medication by the patient. Pharmacists are involved in providing self-management support to the patients. This review evaluates the interventions of pharmacist for patients to improve self-management with diabetes mellitus and also to improve the clinical outcomes of diabetes mellitus. A comprehensive literature search was performed by using different keywords "pharmacist-led intervention," "diabetes," "effect of pharmacist on outcome of diabetes," and "self-management of diabetes" with the help of various electronic databases such as PubMed, Science Direct, Embase, Web of Science, and the Cochrane Library from the beginning of the database through September 2018. The primary outcome was glycated hemoglobin (HbA1c), whereas the secondary outcomes were blood glucose level, blood pressure (BP) measure, body mass index, lipids, adherence to medication, and quality of life. Twenty-five studies comprising 2997 diabetic patients were included in the analysis. Pharmacist-led intervention was involved in all included studies in the form of education on diabetes and its complications, medication adherence, lifestyle, and education about self-management skills. Pharmacist-led interventions are able to reduce HbA1c levels with a mean of 0.75%. Most studies do not expose the material and methods used in pharmacist-led intervention. The variation in the reduction of HbA1c, fasting blood sugar, BP, and lipid profile was due to the lack of this standardization. The included studies indicated that pharmacist-led interventions in diabetes mellitus can significantly improve the outcomes of diabetes mellitus and its complication later on. Hence, these long-term improvements in outcomes added more value of pharmacists in health-care system of the world.

    MyJurnal
    This study aimed to review the availability of sugar-free medicine available in the market using the online Monthly Index of Medical Specialties (MIMS) Malaysia 2016. Data collection was obtained from product information (PI) for prescription medications contained in the MIMS Malaysia 2016. Concise information for each product was collected based on therapeutic class groupings. The therapeutic class obtained from PI was assigned to one of the 11 major therapeutic classes. PI that stated its use in paediatrics was further reviewed for the availability of sugar free ingredient. Each product was then allocated into the poison groups: Group B, Group C and Non-Scheduled Poison. A total of 282 PI items from 336 companies in MIMS Malaysia 2016 that satisfied our eligibility criteria were reviewed. Of the 282 PI items reviewed, most of the products, 169 (59.9%) were sugarbased product, while 87 (30.9%) of them belong to sugar free products. Our study found that most of the medicines reviewed in the MIMS Malaysia 2016 were under Group C (134 of total 282). There is still a high number of sugar-containing medicines despite the promotion of sugar-free medication. Therefore, consumers need to be educated on the use of sugar-free medicines in children to increase the demand and availability in the market.

    UMT Journal of Undergraduate Research, 2020;2(1):9-14.
    MyJurnal
    This experiment was conducted to study the potential of solid electrolyte from the fish waste of Clarias gariepinus for battery application. The battery was one of the important components that supplies electrical energy to users throughout the world, and it strongly contributed to technology development in the economic sector, transportation, residential as well as agriculture. The presence of ammonia in organic fish waste could produce renewable energy and helped to reduce the use of lithium-ion batteries in modern industries. Two different parameters were being observed in this study, which was the quantity of fish and the number of the cell layer. The process of collecting the fish waste was carried out in the hatchery at Universiti Malaysia Terengganu using two methods, which were filtering and soaking. The result showed that the highest value of energy output was 0.430V from waste filtering of 50 fish and 0.207V from soaking in waste of 50 fish. Meanwhile, the lowest energy output was from the tank that contained ten fish with an energy output of 0.177V for filtering and 0.101V for soaking. Besides, for a different number of the cell layer, the highest value of energy output was 0.414V at 25 layers, and the lowest voltage was 0.175V at five layers. Thus, from the study was observed that the produced voltage was dependent on the quantity of fish and the number of the cell layer, when the quantity of fish and number of cell layer increases, the output energy was also increased.

    Knowledge on under-five childhood immunization has been identified as a key factor in determining understanding and compliance to the schedule. Understanding the current levels of knowledge and introducing a health intervention to improve the level will benefit the population to be healthier and reduce morbidity. Materials and Method: A quasi-experimental study was conducted in nurseries in Putrajaya and Cyberjaya, Malaysia from January 2016 to January 2018. 98 respondents from Putrajaya were given the technology based intervention and 98 from Cyberjaya were the wait-listed control group. Respondents answered a validated, self-administered questionnaire at baseline, immediate post-intervention and 3 months post-intervention that were specifically targeted to examine their levels of knowledge on under five childhood intervention. Results: Data was analysed using Statistical Package for Social Science (SPSS) Version 23. The level of knowledge at baseline was 58.9% for the intervention group and 61.7% for the control group with no significant difference between both groups (p=0.651). Immediate post intervention showed a significant difference (p

    Pediculosis capitis among primary school children is always known as the problem of the lower socio-economic class and rural communities. It carries significant consequences to the school children and caregivers. Limited studies have been conducted among the urban populations. Thus, this study aims to investigate the prevalence and predictors of Pediculosis capitis among Urban primary school children in Kuantan. Materials and method: An analytical cross-sectional study using cluster random sampling was carried out in Kuantan, Pahang, Malaysia. A selfadministered validated questionnaire was issued to the participants with purpose to collect socio-demographic data related to age, gender and factors that associated with head lice infestations among primary school children from standard one to six. It was then followed by hair and scalp examination by a well-trained examiners to check the infestation status. The results were analyzed using the chi-squared test and logistic regression analysis. Results: A total of 1347 students from 5 schools were included in this study. Majority of them were males (53.6%), Malays (61.0%), household income between RM1000-RM2999 (32.1%). The overall prevalence was 9.1% (n=122). Multivariate analysis showed that predictors for pediculosis capitis were female gender (OR= 6.02, 95% CI= 2.97-12.21), Indian ethnicity (OR= 5.55 , 95% CI=3.26-9.45), sibling of more than 5 (OR= 2.72 , 95% CI=1.04-7.12) and contact with infested person (OR=2.42, 95% CI=1.58-3.71). Conclusion: The prevalence of Pediculosis capitis among urban primary school children in Kuantan, Pahang is endemic (9.1%) and predictors are female genders, Indian ethnicity, having siblings of more than 5 and contact with infested person. Hence, preventive measures are necessary to reduce the transmission of head lice among school children.

    Carbon monoxide measurement is one of the biomedical risk assessments in smoking cessation. With the advancement in medical devices, risk assessment among smoker using carbon monoxide can be an effective intervention for quit smoking. A systematic review was conducted on the effectiveness of using carbon monoxide measurement in smoking cessation intervention. Material and methods: A systematic review and narrative synthesis were done using PRISMA guideline. A broad database search on English literature was conducted including Medline, PubMed, Scopus and Science Direct from 2008 till 2017. Additional studies were also searched through snowballing technique by searching the bibliographies of selected studies. Five studies met the criteria with two studies were done in clinical settings while the other was done at population settings. The studies were conducted in the United States of America, United Kingdom and South Korea. All study were two-arm randomized controlled trials with variation in the outcome measurement mainly intention to quit, quit attempt and smoking abstinence. There was also variation in the duration of follow up ranging from 1 week to 12 months. Results: Only three studies found statistically significant increased in motivation or intention to quit smoking but only at 1 month follow up. All five study found no significant difference in frequency of quit attempt or smoking abstinence. Most of the studies recruited participants based on voluntary participation thus limiting the generalizability of the results. Conclusions: The present review has found limited studies on the effect of carbon monoxide measurement intervention for quit smoking. It may only be beneficial at the motivational level and not translated into behavioural changes. However, the effect too was short term and not sustained in the long term.
  18. Fulltext A Comparative Study on Suitability of Model-Free and Model-Fitting Kinetic Methods to Non-Isothermal Degradation of Lignocellulosic Materials

    Polymers (Basel), 2021 Jul 29;13(15).
    PMID: 34372105 DOI: 10.3390/polym13152504
    The thermal kinetic modeling is crucial for development of sustainable processes where lignocellulosic fuels are a part of chemical system and their thermal degradation eventuates. In this paper, thermal decomposition of three lignocellulosic materials (bagasse, rice husk, and wheat straw) was obtained by the thermogravimetric (TG) technique and kinetics was analyzed by both model-fitting and isoconversional (model-free) methods to compare their effectiveness. Two models selected from each class include Arrhenius and Coats-Redfern (model-fitting), and Kissinger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO) (model-free). The formal model-fitting approach simulating the thermal decomposition of solids by assuming a fixed mechanism was found to be unduly facile. However, activation energy (E) values calculated from two model-fitting techniques were considerably different from each other with a percentage difference in the range of 1.36% to 7.65%. Particularly, both model-fitting methods predicted different reaction mechanism for thermal disintegration of lignocellulosic materials (two-dimensional diffusion (D2) by Arrhenius and one-dimensional diffusion (D1) by Coat-Redfern method). Conversely, the model-free routine offers a transformation of mechanism and activation energy values throughout reaction and is, therefore, more authentic to illustrate the complexity of thermal disintegration of lignocellulosic particles. Based on the model-free kinetic analysis, the lignocellulosic materials may be devised in following order of activation energy: rice husk > bagasse > wheat straw, by both KAS and FWO methods with a percentage difference no more than 0.84% for fractional conversion up to 0.7. Isoconversional approach could be recommended as more realistic and precise for modeling non-isothermal kinetics of lignocellulosic residues compared to model-fitting approach.

    This study investigated the accumulation of debris at four sites, namely, Gebeng, Batu Hitam, Cherok Paloh, and Air Leleh, along the Pahang coastline, Peninsular Malaysia from March 2019 to February 2020. Plastic was the dominant debris (86.1%) and followed by cloth/fabric-based debris (6.0%), processed lumber debris (3.3%), rubber (2.7%), glass (1.5%), and metal (0.4%). The land-based debris (82.0%) was the major source of the deposition of marine waste. A statistically significant relationship was found between the seasonal variation and marine debris density in tidal and seasonal current along the Pahang coastline. In general, the Northeast Monsoon season had a higher amount of debris than the Southwest Monsoon season.

    Food distribution and diversity is a significant factor that determines the habitat and site selection of avian species. Its effects on the health, reproduction, survival rate, diversity indices, population structure and home range of avian species. In wetland ecosystem, bird home range and population structure is influenced by richness and diversity of food resources and availability of suitable foraging sites. The aim of the study was to ascertain the food variety of Lesser Whistling Duck – Dendrocygna javanica in Paya Indah Wetland Reserve (PIWR). A scan method was employed from strategic places or blinds using a spotting scope and binocular to determine the food selection and density by Distance sampling point count method. Food items were categorised into the aquatic plants (AP), aquatic invertebrates (AIV), aquatic vertebrates (AV), terrestrial plants (TP), terrestrial vertebrates (TV) and terrestrial invertebrates (TIV). Distance analysis indicated that PIWR harboured 3.88 ± 0.00 birds per ha (n = 188 individuals). In addition, the results revealed that higher bird relative abundance of Lesser Whistling Duck concentrated in the shallow of Belibis lake that was rich in submerged and emergent vegetation (Eleocharis dulcis, Philydrum lanuginosum, Utricularia vulgaris, and Potamogeton perfoliatus). Kruskal–Wallis H test showed that food items were significantly different. Lesser Whistling Duck showed strong correlationship with AIV (r2 = 1.00, P < 0.05) and negative relationship with water TP (r2 = –0.061, P< 0.05). The regression model highlighted that Lesser Whistling Duck significantly preferred aquatic invertebrates, r2 = –0.686±0.68; P
