    Nutrition, 1995 Sep-Oct;11(5 Suppl):517-20.
    PMID: 8748212
    Iodine as a trace element is an essential nutrient for human growth and development. Its potential impact on manpower development in third world countries are of special concern, primarily due to iodine deficiency disorders (IDD) such as goiter, hypothyroidism, and cretinism. IDD of mild to moderate severity are still found in Malaysia. The prevalence ranges from almost zero in many developed urban areas to more than 90% in some rural parts of Malaysia, especially in Sabah and Sarawak. The endemias were associated with low urinary excretion of iodine among the population, indicating poor iodine intake and low iodine content in the environment. Water and salt iodination strategies are being planned to eradicate the disease by the year 2000.
  2. Fulltext Screening diabetes using 2HPP urine sugar. [Ujian tapisan diabetes mellitus menggunakan 2HPP gula urin.]

    Family Physician, 1989;1(1):42-43.
    The validity of the 2-hour post-prandial (2HPP) urine glucose was determined among a Malay community in Kuala Selangor. Fifty glycosuric and 80 non-glycosuric samples had their capillary blood glucose and fasting blood sugar tested to determine their diabetic status. It was found that the test was very sensitive but less specific (sensitivity 100% and specificity 72.1%). Samples with 2HPP urine glucose of 3 + had a higher probability of being diabetic than the others.
  3. Fulltext Development of a voice activity controlled noise canceller
    Abid Noor AO, Samad SA, Hussain A
    Sensors (Basel), 2012;12(5):6727-45.
    PMID: 22778667 DOI: 10.3390/s120506727
    In this paper, a variable threshold voice activity detector (VAD) is developed to control the operation of a two-sensor adaptive noise canceller (ANC). The VAD prohibits the reference input of the ANC from containing some strength of actual speech signal during adaptation periods. The novelty of this approach resides in using the residual output from the noise canceller to control the decisions made by the VAD. Thresholds of full-band energy and zero-crossing features are adjusted according to the residual output of the adaptive filter. Performance evaluation of the proposed approach is quoted in terms of signal to noise ratio improvements as well mean square error (MSE) convergence of the ANC. The new approach showed an improved noise cancellation performance when tested under several types of environmental noise. Furthermore, the computational power of the adaptive process is reduced since the output of the adaptive filter is efficiently calculated only during non-speech periods.

    PMID: 7709757
    A study was conducted to compare the urinary iodine concentrations in populations from Pahang, Central Malaysia, with those in the capital city Kuala Lumpur, and to compare those of Malays from villages at Batu Talam, Batu Malim, FELDA Sungai Koyan and Hulu Sungai with neighboring aboriginal settlements at Lanai and Buntu. Two hundred and forty urine samples were collected randomly among the population (male 1 1 1 and female 129). The urinary iodine concentrations, measured by the ashing method, among Malays were as follows: Batu Talam 1.1-7.6 micrograms/dl, Batu Malim 1.4-6.6 micrograms/dl, FELDA Sungai Koyan 0.5-6.9 micrograms/dl and Hulu Sungai 0.6-9.9 micrograms/dl. Among aborigines, the urinary iodine levels were 0.1-2.9 micrograms/dl in Lanai and 1.7-6.5 micrograms/dl in Buntu. There was a significant difference in the levels of urinary iodine with regard to gender, but not regarding age. The aborigines had significantly lower iodine levels than Malays (P < 0.001). This difference was also significant with regard to location. The urinary iodine content in Kuala Lumpur was the highest and that in the aboriginal Lanai village was the lowest. Thus, the study showed that the levels of iodine in the urine were influenced by ethnicity and geographic location.
  6. Fulltext Nutritional status of women and children in Malaysian rural populations
    Ali O, Isa ZM
    Asia Pac J Clin Nutr, 1995 Sep;4(3):319-24.
    PMID: 24394359
    This study was conducted to investigate the nutritional status of the rural population in Malaysia, especially women and children. A total of 262 women aged 18 and over and 183 children aged 2-6 years were selected using multistage cluster sampling from four locations in rural areas. It was found that the prevalence of malnutrition among children 2-6 years old ranged between 25.5% in the Malays Felda settlement scheme to 80% in the Orang Asli settlement. Malnutrition was associated with worm infestations, bottle feeding and early weaning. More than 30% of Orang Asli women were malnourished compared to less than 15% of Malay Felda settlement women. On the other hand, Malay women in the land settlement scheme had a higher risk of developing overweight and diabetes. Goitre was found among 11.5% of children; however, no cretinism was found. Breast feeding was still a common practice among rural mothers, but inadequate health education tended to reduce the duration of breast feeding and increased early weaning. Upgrading women's status in the rural areas will ultimately improve the nutritional and health status of the children and community as a whole.

  8. Fulltext Socioeconomic, social behaviour and dietary patterns among Malaysian aborigines and rural native Malays
    Ali O, Shamsuddin Z, Khalid BA
    Med J Malaysia, 1991 Sep;46(3):221-9.
    PMID: 1839916
    The socioeconomic, social behaviour and dietary pattern of 100 Aborigines and Malays, aged 7 years and above from Kuala Pangsoon, Selangor Malaysia were studied by using pretested questionnaires. The individual's dietary intake was estimated using 24 hour recall for 3 days within one week which was chosen at random. The household's food consumption pattern was evaluated using food frequency questionnaires. There was no difference in the total income per month for both communities, as well as the educational attainment of the head of household and property ownership. The proportion of smokers among the Aborigines and the Malays was almost similar (33%) but the percentage of heavy smokers was higher among Aborigines compared to Malays. One third of the Aborigines regularly consume alcohol. The main energy source for both communities was rice, sugar and cooking oil whilst fish and eggs were the main sources of protein. More than 50% of the Aborigines take tapioca or tapioca leaves at least once a week compared to less than 20% among the Malays. There was no significant different in the intake of energy, protein and carbohydrate between the groups. However, the Aborigines take less fats and iron compared to the Malays. The difference in terms of smoking, drinking habit and dietary intake may determine the distribution of disease in both communities.

    PMID: 6544926
    A study was carried out to study lite prevalence of hypertension amongst rural Malays living in two villages in Kuala Selangor district. Simple random sampling of households was carried out and all members 15 years and above were examined. Out of 359 persons examined, 92 (25.6%) had hypertension. A significant increase in prevalence was observed with increasing age and in smokers. Prevalence rates did not differ significantly in the two sexes and with income. Only 38 of the hypertensives were known cases. It was found that 78. 7% of them had been detected within less than five years and 81.6% had undergone medical treatment. It is proposed that preventive programmes in hypertension be introduced in rural health services and a national prevalence survey be conducted.
  10. Fulltext Emerging IoT domains, current standings and open research challenges: a review
    Ali O, Ishak MK, Bhatti MKL

    PMID: 34541307 DOI: 10.7717/peerj-cs.659
    Over the last decade, the Internet of Things (IoT) domain has grown dramatically, from ultra-low-power hardware design to cloud-based solutions, and now, with the rise of 5G technology, a new horizon for edge computing on IoT devices will be introduced. A wide range of communication technologies has steadily evolved in recent years, representing a diverse range of domain areas and communication specifications. Because of the heterogeneity of technology and interconnectivity, the true realisation of the IoT ecosystem is currently hampered by multiple dynamic integration challenges. In this context, several emerging IoT domains necessitate a complete re-modeling, design, and standardisation from the ground up in order to achieve seamless IoT ecosystem integration. The Internet of Nano-Things (IoNT), Internet of Space-Things (IoST), Internet of Underwater-Things (IoUT) and Social Internet of Things (SIoT) are investigated in this paper with a broad future scope based on their integration and ability to source other IoT domains by highlighting their application domains, state-of-the-art research, and open challenges. To the best of our knowledge, there is little or no information on the current state of these ecosystems, which is the motivating factor behind this article. Finally, the paper summarises the integration of these ecosystems with current IoT domains and suggests future directions for overcoming the challenges.

    Diabetes mellitus and its main complication, nephropathy, ajjbcts the economic wellbeing and quality of Iife of the sufferers and the population. A matched case control study was conducted in September 1998 to investigate the factors involved with nephropathy such as diabetic control, smoking, hypertension, familv history of diabetes and diabetic duration. Respondents were classyied based on the presence of microalbuminuria or macroalbuminuria, Seventy-two pairs of case and control were studied Duration of diabetes Q2 = 0.005), presence of lethargy and weakness prior to diabetes diagnosis @7 = 0.019), duration of smoking @7 = 0.014), duration of hypertension @2: 0.000), systolic hypertension Qu= 0e 025), uncontrolled diabetes with poor HbA1c level (v= 0.02Q and lack of diabetes knowledge Q2 = 0.037) were jbctors which related signyicantlv to nephropathy by univariate anahrsis. In multivariate anahrsis, systolic hypertension (p = 0.0015), lack of diabetes knowledge (17 = 0.0197), presence of lethargy symptom Q7 = 0.0027), prolonged diabetic duration @ = 0.0301) and higher body mass indices (p = 0. 0213) were predictors to diabetic nephropathy.
  12. Toxicity profile of choline chloride-based deep eutectic solvents for fungi and Cyprinus carpio fish
    Juneidi I, Hayyan M, Mohd Ali O
    Environ Sci Pollut Res Int, 2016 Apr;23(8):7648-59.
    PMID: 26743645 DOI: 10.1007/s11356-015-6003-4
    An investigation on the toxicological assessment of 10 choline chloride (ChCl)-based deep eutectic solvents (DESs) towards four fungi strains and Cyprinus carpio fish was conducted. ChCl was combined with materials from different chemical groups such as alcohols, sugars, acids and others to form DESs. The study was carried out on the individual DES components, their aqueous mixture before DES formation and their formed DESs. The agar disc diffusion method was followed to investigate their toxicity on four fungi strains selected as a model of eukaryotic microorganisms (Phanerochaete chrysosporium, Aspergillus niger, Lentinus tigrinus and Candida cylindracea). Among these DESs, ChCl:ZnCl2 exhibited the highest inhibition zone diameter towards the tested fungi growth in vitro, followed by the acidic group (malonic acid and p-toluenesulfonic acid). Another study was conducted to test the acute toxicity and determine the lethal concentration at 50 % (LC50) of the same DESs on C. carpio fish. The inhibition range and LC50 of DESs were found to be different from their individual components. DESs were found to be less toxic than their mixture or individual components. The LC50 of ChCl:MADES is much higher than that of ChCl:MAMix. Moreover, the DESs acidic group showed a lower inhibition zone on fungi growth. Thus, DESs should be considered as new components with different physicochemical properties and toxicological profiles, and not merely compositions of compounds.

    PMID: 24394705
    A study was undertaken in FELDA (Federal Land Development Authority) resettlement scheme areas in Pahang, Malaysia, to determine the effectiveness of group dietary counselling in motivating diabetic patients to achieve good dietary habits, and weight and diabetes control. Sixty-one non-insulin dependent diabetes mellitus (NIDDM) patients were randomly assigned to either the experimental or control group. The experimental group received six sessions of group dietary counselling over 5 months and the control group received mass media diabetes-educational program during the same period. The one hour group dietary counselling sessions discussed general knowledge of diabetes, food groups for meal planning, the importance of dietary fibre-rich foods, types of fat in food, exercise and weight control. The experimental group met monthly with a dietitian as a counsellor. Effectiveness was assessed by improvement in food choice, and decline in percentage glycated haemoglobin (total HbA1) or body mass index (BMI). Measurements were made at a baseline visit, every two months during the six month program, and six months afterwards. Patients in the experimental group improved their food choices, resulting in a healthier diet high in unrefined carbohydrates and dietary fibre rich foods, and low in fat. There were significant reductions of their percentage total HbA1 levels and BMI following the counselling sessions, which decreased further six months after the program compared with patients in the control group. Thus group dietary counselling is effective in motivating NIDDM patients to achieve better food choice, and related weight and glycaemic control in a Malaysian setting.

    In the present research work, a comprehensive tool for cumulative ecotoxicological impact assessment of ionic liquids (ILs) to aquatic life has been constructed. Using the probabilistic tool, impact of individual ILs to a group of aquatic species is assessed by chemical toxicity distributions (CTDs). The impact of group of ILs to individual aquatic species is assessed by species sensitivity distributions (SSDs). Acute toxicity data of imidazolium ILs with chloride (Cl-), bromide (Br-), tetrafluoroborate (BF4-), and hexafluorophosphate (PF6-) anions are used in CTD and SSD. Allowable concentrations for a group of Imidazolium ILs with the same mode of action (SMOA) to five aquatic species; Daphnia magna, Vibrio fischeri, Algae, Zebrafish, and Escherichia coli are estimated by CTDs. It has been concluded that 1-Butyl-3-methylimidazolium chloride (BMIMCl) possess the lowest risk at an acceptable risk value of 750 × 10-5 mmol/L which is 12% less than that of OMIMCl. Furthermore, the sensitivities towards the aquatic species reveal that from the studied ILs, BMIMBF4 with an acceptable risk value of 3200 × 10-5 mmol/L is the most suitable IL towards the selected aquatic species. Hence, current work provides cumulative allowable concentrations and acceptable risk values for ILs which release to aquatic compartment of ecosystem.

    PMID: 20924153
    OBJECTIVES: To determine the relationship between semen quality and exposure to pesticide residues.

    METHODS: A cross-sectional study was conducted among male farmers from 3 different communities in Sabah, Malaysia. A total of 152 farmers participated in this study of whom 62 farmers had been exposed to either paraquat or malathion or both to varying extents. Questionnaires were designed to record a history of pesticides exposure and other potential risk factors among farmers. All semen samples were collected, processed and analyzed by qualified personnel based on WHO guidelines. Volume, pH, sperm concentration, motility, morphology and WBC count were examined and recorded. The association between pesticide exposure and semen parameters was highly significant.

    RESULTS: The mean values of volume, pH, sperm concentration, motility, and WBC count were significantly less in the exposed group than in compared with the non-exposed group, with p<0.005. Those who were exposed to pesticides had greater risk of having abnormal semen parameters than those in with the non exposed group, with p values of less than 0.05. The comparison between semen qualities such as lower sperm count, motility and higher percentage of sperm abnormality of those exposed to different types of pesticides (paraquat and malathion) showed no significant differences.

    CONCLUSION: The results showed a significant decline in semen quality with a decline in sperm count, motility and higher percent of teratospermia among subjects with pesticide exposure, and those who were exposed to pesticides had significantly 3 to 9 times greater risk of having abnormal semen parameters.

    Metabolic syndrome (MetS) is defined as a cluster of known disorders that increase the risk for morbidity and mortality from cardiovascular diseases (CVD) and type 2 diabetes mellitus. This cross sectional study was carried out to estimate the prevalence of MetS using Adult Treatment Panel 3 (ATP 3) classification and socio-demographic and lifestyle factors contributing to metabolic syndrome among rural indigenous Malaysian population from Perak state, Malaysia which included 148 rural Malay and 145 Orang Asli(OA) individuals. This community based cross-sectional study revealed that the prevalence of MetS was significantly higher among Malays (27.7%) as compared to Orang Aslis (13.8%). Overall Prevalence of Metabolic syndrome in the rural indigenous Malaysian population was 20.8%. Prevalence of abdominal obesity and high blood pressure were significantly higher among Malays as compared to OA population. Metabolic syndrome was significantly higher among those above 45 years of age group in overall rural indigenous Malaysian population and among OA. The prevalence of MetS was significantly higher among those who were obese and overweight and among Malays who were regularly taking snacks between meals. There was no significant association between other dietary risk factors, smoking, alcohol use or physical activity with metabolic syndrome.

    Intestinal parasitic infections are among the most common diseases affecting mankind causing major public health problems to billions of people living in developing countries. The aim of this study is to determine the prevalence of intestinal parasites in various communities residing in different habitats in Malaysia and compare the findings with 101 studies conducted over the past 42 years (1970-2013). A cross-sectional study design was conducted with the aid of a questionnaire to collect relevant information about the study population. Faecal samples were examined using the direct smear and formal ether sedimentation techniques. A total of 342 children were examined amongst whom 24.6% were positive for intestinal parasitic infections. Results showed that 32.3% of rural children, 20.6% of urban squatters and 5.4% of children from flats were positive for one or more parasites. The most common parasite encountered was Trichuris trichiura (20.2%) followed by Ascaris lumbricoides (10.5%) and hookworm (6.7%). No case of hookworm was reported in urban children whereas 12.2% of rural children were positive. The most common protozoan parasite detected was Entamoeba coli (3.2%) followed by Giardia intestinalis (1.8%), Entamoeba histolytica (1.8%) and Blastocystis hominis (1.2%). Nearly one-fifth (18.4%) of the children had single infection followed by double (12.0%) and triple infections (1.2%). Orang Asli (indigenous) children (44.3%) had the highest infection rate followed by Indians (20.2%), Malays (14.0%) and Chinese (11.9%). Twenty-eight studies carried out on plantation communities with regards to intestinal parasitic infections in Malaysia from 1970 to 2013 showed a steady decline in the prevalence rate ranging from 95.0% in the seventies to 37.0 % in 2012. Intestinal parasitic infections were more common in Orang Asli communities with prevalence ranging from over 90% in the seventies and fluctuating below 70% in most studies between 2000 to 2013 except for two studies that showed a prevalence of 98.2% and 100%. The prevalence rate among urban squatters, urban residents and those living in flats showed dramatic decrease in prevalence rate.

    PMID: 22692473
    This study was conducted to determine the effects of increased edible palm oil consumption on community health status in the aboriginal communities in Tual Post (treatment group) and Sinderut Post (control group), Kuala Lipis, Pahang. Nutritional status, blood pressure, lipid profiles, fasting blood glucose (FBG), vitamin E (alpha-tocopherol) levels and lipid peroxidation product (malonaldehyde) levels were taken as indicators of health status. This is a pre-and post-controlled community trial in which similar variables were measured in each group. Every family of 2-6 household members was given 2-5 kg cooking palm oil per month for a period of 18 months. All subjects were measured for height (cm), weight (kg) and waist-hip ratio (WHR). For calorie intake measurement, house-to-house interviews were conducted using 24-hour dietary recall method. Blood pressure, percent body fat, lipid profiles, namely total cholesterol, high density lipoprotein cholesterol, triglyceride and fasting blood glucose (FBG) were also measured. Vitamin E (alpha-tocopherol) levels and lipid peroxidation products (MDA) were also determined. There was a significant increase (p<0.05) in percent body fat (28.1%) and calorie intake (17.2%) following palm oil consumption. The proportion of fat intake as an energy source also increased from 4.6% to 33.9%. There was a reduction in the systolic blood pressure following consumption (p<0.05). However, diastolic blood pressure did not change. A significant decrease (p<0.05) was observed in total cholesterol, low density lipoprotein and triglyceride. No particular pattern in fasting blood glucose levels was observed among the indigenous inhabitants following palm oil consumption. There was a significant increase in alpha-tocopherol levels (p<0.0001) and a decrease in MDA levels (p<0.0001) following consumption. In conclusion, high consumption of edible palm oil for 18 months was found to be not harmful to health. For the Malaysian aborigines, it serves as a good source of fat and energy.
  19. Fulltext Battery characterization for wireless sensor network applications to investigate the effect of load on surface temperatures
    Ali O, Ishak MK, Ooi CA, Bhatti MKL
    R Soc Open Sci, 2022 Feb;9(2):210870.
    PMID: 35127112 DOI: 10.1098/rsos.210870
    Wireless sensor networks (WSN) are commonly used in remote environments for monitoring and sensing. These devices are typically powered by batteries, the performance of which varies depending on environmental (such as temperature and humidity) as well as operational conditions (discharge rate and state-of-charge, SOC). As a result, assessing their technical viability for WSN applications requires performance evaluation based on the aforementioned stimuli. This paper proposes an efficient method for examining battery performance parameters such as capacity, open-circuit voltage (OCV) and SOC. Four battery types (lithium-ion, lithium-polymer, nickel-metal hydride and alkaline) were subjected to IEEE 802.15.4 protocol-based discharge rates to record the discharge characteristics. Furthermore, the combined effect of discharge rates on battery surface temperature and OCV variations was investigated. Shorter relaxation times (4-8 h) were observed in lithium-based batteries, resulting in faster energy recovery while maintaining rated capacity. It was observed that nearly 80% of the voltage region was flat, with minor voltage variations during the discharge cycle. Furthermore, lithium-based batteries experienced negligible changes in surface temperatures (approx. 0.03°C) with respect to discharge rates, making them the best battery choice for low-power applications such as WSNs.
  20. Fulltext Attitudes towards vasectomy and its acceptance as a method of contraception among clinical-year medical students in a Malaysian private medical college
    Ohn Mar S, Ali O, Sandheep S, Husayni Z, Zuhri M
    Singapore Med J, 2019 Feb;60(2):97-103.
    PMID: 29876579 DOI: 10.11622/smedj.2018065
    INTRODUCTION: This study explored attitudes towards vasectomy and its acceptance as a method of contraception among clinical-year medical students, and determined the association between their demographic characteristics, and attitudes and acceptance.

    METHODS: A cross-sectional survey was conducted among clinical-year medical students from a Malaysian private medical college using a self-administered questionnaire.

    RESULTS: There were 330 participants with a female preponderance and a mean age of 22.0 ± 1.1 years. The largest proportion of respondents were from Year 3. The vast majority were ethnically Malay (91.8%) and followed Islam (92.4%). Overall, 60.9% of participants had a positive attitude towards vasectomy and 76.0% showed good acceptance. Gender, academic year, ethnicity and religion variables were not associated with attitudes and acceptance (p > 0.05). A significantly higher proportion of male respondents thought that vasectomy was religiously forbidden and would give a bad impression. A significantly higher proportion of Year 5 students agreed to the statement 'I would recommend vasectomy to relatives, friends and people close to me' compared to Year 3 and 4 students.

    CONCLUSION: Students' perception of vasectomy as a contraceptive method was encouraging. Our results suggest that their knowledge improved as medical training progressed, and attitudes evolved for the better irrespective of their traditional, cultural and religious beliefs - highlighting the importance of providing students with evidence-based learning about male sterilisation, which is more cost-effective and is associated with lower morbidity than female sterilisation. A qualitative study involving students from different ethnicities and religions would provide a better understanding of this subject.
