    PMID: 6969497
    1829 school-boys of Singapore comprised of 849 Chinese, 469 Malays and 511 Indians were investigated for the incidence of red-green colour-blindness with Ishihara's plates. The incidence of red-green colour-blindness was found to be 3.8%, 4.5% and 4.5%, respectively in Chinese, Malay and Indian boys. The incidence among the different dialect groups was variable with the highest incidence of red-green colour-blindness among Mandarin speaking group (14.3%), followed by Hainanese speaking (6.7%) and other dialect groups of Chinese (2.8% to 4.5%). The incidence of red-green colour-blindness was higher in the older boys compared with the younger boys when all the three ethnic groups are combined.

    A 43-year-old woman developed abdominal pain and diarrhea following a travel to Malaysia. Examinations in another hospital proved no evidence of infection, an empirical antibiotic therapy with ciprofloxacin yielded no benefit. One and a half year later, the patient was admitted to our department because of persistent diarrhea and wasting. Laboratory tests showed megaloblastic anemia, folate deficiency and steatorrhea. Stool specimens for bacterial pathogens and parasites were negative. Endoscopy and biopsy from the distal portion of the duodenum revealed broadening and shortening of the villi and an increased infiltration of the lamina propria by chronic inflammatory cells (plasma cells and lymphocytes). In conclusion, diagnosis of tropical sprue was established. The therapy comprised of tetracycline for six weeks and folic acid for six months. Subsequently, the diarrhea disappeared, the patient continuously gained weight and was free of any complaints. The complete remission following this regimen proved the suspected diagnosis. Differential diagnosis in any patient who recently returned from the tropics may be a challenge. Tropical sprue predominantly occurs during or after a longer stay in endemic areas. However, if chronic diarrhea and signs of malabsorption develop after a short journey to India, South-East Asia and parts of the Caribbean, tropical sprue has to be considered, too.

  4. Immunoglobulin levels in various clinical groups of human Brugian filariasis in Malaysia
    Sim BK, Mak JW, Kwa BH
    Z Parasitenkd, 1983;69(3):371-5.
    PMID: 6880344
    Quantitation of serum immunoglobulin M, G, A, D and E levels was carried out in Malaysians with Brugia malayi infections. Results showed highly elevated levels of IgM and IgE as well as moderately elevated levels of IgG. These were most significant in patients with tropical pulmonary eosinophilia or elephantiasis. Serum IgE levels were extremely high in microfilaraemic patients (6,060 +/- 3,958 IU ml) probably due to a constant antigenic stimulation by dead and dying microfilariae.

    Shakri NM, Salleh WMNHW, Khamis S, Mohamad Ali NA, Shaharudin SM
    Z Naturforsch C J Biosci, 2020 Nov 26;75(11-12):473-478.
    PMID: 32628641 DOI: 10.1515/znc-2020-0097
    Polyalthia is one of the largest genera in the Annonaceae family, and has been widely used in folk medicine for the treatment of rheumatic fever, gastrointestinal ulcer, and generalized body pain. The present investigation reports on the extraction by hydrodistillation and the composition of the essential oils of four Polyalthia species (P. sumatrana, P. stenopetalla, P. cauliflora, and P. rumphii) growing in Malaysia. The chemical composition of these essential oils was determined by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). The multivariate analysis was determined using principal component analysis (PCA) and hierarchical clustering analysis (HCA) methods. The results revealed that the studied essential oils are made up principally of bicyclogermacrene (18.8%), cis-calamenene (14.6%) and β-elemene (11.9%) for P. sumatrana; α-cadinol (13.0%) and δ-cadinene (10.2%) for P. stenopetalla; δ-elemene (38.1%) and β-cubebene (33.1%) for P. cauliflora; and finally germacrene D (33.3%) and bicyclogermacrene for P. rumphii. PCA score and HCA plots revealed that the essential oils were classified into three separated clusters of P. cauliflora (Cluster I), P. sumatrana (Cluster II), and P. stenopetalla, and P. rumphii (Cluster III) based on their characteristic chemical compositions. Our findings demonstrate that the essential oil could be useful for the characterization, pharmaceutical, and therapeutic applications of Polyalthia essential oil.

    PMID: 21654922
    AIMS: In Malaysia, Shigella spp. is the third most common bacterial agent responsible for childhood diarrhoea. This study was conducted to determine the prevalence and antimicrobial susceptibility patterns of Shigella spp. isolated from patients admitted to the Hospital Universiti Sains Malaysia from January 2001 to December 2009. SUBJECTS AND METHODS: A hospital-based retrospective study was used. Stool samples from patients were cultured using a standard culture method. Shigella spp. isolates were identified by biochemical and serological methods, and the antimicrobial susceptibility pattern was evaluated using the Kirby-Bauer disc-diffusion method. RESULTS: A total of 138 Shigella spp. were isolated from a total of 14,830 routine stool specimens, yielding an isolation rate of 0.93% that corresponded to 9.99% of the 1,381 bacterial pathogens isolated. Of these isolates, S. sonnei was the predominant species, followed by S. flexneri and S. boydii. Seasonal variation was noticed, and no significant differences were detected in the demographic data for S. flexneri and S. sonnei. The susceptibility of all isolated Shigella strains was tested against seven antibiotics. Ceftriaxone (99.1%), ciprofloxacin (98.4%), and nalidixic acid (93.8%) were effective against the Shigella strains, whereas tetracycline and trimethoprim-sulfamethoxazole exhibited high frequencies of resistance (58.4% and 53.8%, respectively). CONCLUSION: This study is important for public health education aimed at reducing the morbidity and mortality associated with Shigella spp. infection. Our results also will be helpful for paediatricians and microbiologists in the selection of appropriate antibiotics for the management of diarrhoea.

    Alabed AAA, Elengoe A, Anandan ES, Almahdi AY
    Z Gesundh Wiss, 2020 Oct 14.
    PMID: 33078089 DOI: 10.1007/s10389-020-01395-9
    Background: There is a major public health challenge threatening the world with the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which emerged in December 2019 from Wuhan, China.

    Objective: The aim of this study was to assess the knowledge, attitude and practice regarding COVID-19 and its transmission, causes and prevention among people living in Malaysia.

    Methods: A cross-sectional study was conducted among people living in Malaysia by using an online survey in March and April 2020.

    Results: Out of 520 respondents, the mean age was 36.9 ± 14.9, between 19 and 67 years with the majority being female. Most respondents had good knowledge, attitude and practice towards COVID-19 with mean ± sd 18.2 ± 1.7, 5.2 ± 1.1 and 4.1 ± 1.4, respectively. In addition, the majority had good knowledge regarding cause, mode of transmission, signs and symptoms, prevention and treatment and quarantine measures after answering 21 questions.

    Conclusion: To date, there is no specific treatment or vaccine for COVID-19, thus staying at home is the best preventive measure to curb the further growth of positive cases in the country. These findings could provide an insight in designing effective preparedness for future pandemic outbreaks.

    PMID: 32837842 DOI: 10.1007/s10389-020-01316-w
    Aim: The first Covid-19 cases were reported in Malaysia on 25 January 2019 followed by a quiescent period before an upward swing of the cases at the end of February 2020, partly attributed to mass gathering during a religious event. This short communication aims to provide an overview of the measures taken by the Malaysian Government in response to Covid-19, and of the effectiveness of the Movement Control Order.

    Subjects and methods: This short communication reviews articles and government announcements related to containment measures and the Movement Control Order of Malaysia, and graphically presents data pertinent to Covid-19 in Malaysia in order to show the relationship between fluctuations in Covid-19 cases and movement control.

    Results: At the onset of the Covid-19 outbreak, Malaysia had initiated travel restrictions and quarantine; but with a persistent increase in new Covid-19 cases, the Movement Control Order was finally rolled out on 18 March 2020, requiring closure of all businesses except those providing essential services and items. Enforcement of the order was tightened progressively, resulting in significant improvement of compliance, while other interventions such as tracking of potential contacts and medical screening were underway, and the media continued to provide updates and general advices. The numbers of new and active Covid-19 cases started showing evident downtrends from mid-April, thus indicating the effectiveness of movement control and its compliance.

    Conclusion: The article provides insight into crucial factors contributing to the success of movement control to effectively contain Covid-19, and highlights the need to prevent future upsurge through continuous monitoring and enforcement.

  12. The state of shared decision making in Malaysia
    Lee YK, Ng CJ
    Z Evid Fortbild Qual Gesundhwes, 2017 Jun;123-124:66-68.
    PMID: 28527637 DOI: 10.1016/j.zefq.2017.05.019
    Shared decision making (SDM) activities in Malaysia began around 2010. Although the concept is not widespread, there are opportunities to implement SDM in both the public and private healthcare sectors. Malaysia has a multicultural society and cultural components (such as language differences, medical paternalism, strong family involvement, religious beliefs and complementary medicine) influence medical decision making. In terms of policy, the Ministry of Health has increasingly mentioned patient-centered care as a component of healthcare delivery while the Malaysian Medical Council's guidelines on doctors' duties mentioned collaborative partnerships as a goal of doctor-patient relationships. Current research on SDM comprises baseline surveys of decisional role preferences, development and implementation of locally developed patient decision aids, and conducting of SDM training workshops. Most of this research is carried out by public research universities. In summary, the current state of SDM in Malaysia is still at its infancy. However, there are increasing recognition and efforts from the academic institutions and Ministry of Health to conduct research in SDM, develop patient decision support tools and initiate national discussion on patient involvement in decision making.

  13. Fulltext Shared decision-making in Malaysia: Legislation, patient involvement, implementation and the impact of COVID-19
    Lee YK, Ng CJ, Lee PY, Tong WT, Sa'at H
    Z Evid Fortbild Qual Gesundhwes, 2022 Jun;171:89-92.
    PMID: 35610129 DOI: 10.1016/j.zefq.2022.04.020
    Shared decision making (SDM) activities in Malaysia began around 2010. The rise in the numbers of patients with chronic disease in Malaysia underscores a growing need for doctors to practice patient-centred care and SDM as more Malaysians come into regular contact with health decision-making scenarios. Recent guidelines for medical professionalism have emphasized that options and risks be discussed in consultations, especially for procedures with risk of adverse outcomes. Although SDM is not legally required, principles of SDM are applied in legal judgements on informed consent. Research on SDM has grown to include the adoption of patient and public involvement in research, an increased emphasis on incorporating local cultural values in SDM, and implementation of SDM in Malaysia's health system and organizational culture. While COVID-19 hindered the progress of SDM research, one positive development was that vaccination choices heightened public consciousness about personal decisional autonomy and the need to discuss pros and cons with doctors before making a medical decision.

  14. Advance Care Planning in Malaysia
    Lim ZN, Ng WJ, Lee CC
    Z Evid Fortbild Qual Gesundhwes, 2023 Aug;180:103-106.
    PMID: 37357108 DOI: 10.1016/j.zefq.2023.05.019
    BACKGROUND: In Malaysia, advance care planning is still in its infancy. There is no national implementation of Advance Care Planning.

    AIMS: To describe the national state of advance care planning development in Malaysia METHODS: Review of relevant advance care planning literature locally and internationally was undertaken.

    RESULTS: Positive development in Malaysia includes implementation of advance care planning at institutional level, initiatives to develop educational programmes as well as research activities to understand the attitude and perception of patients on advance care planning. However, there remain challenges, including lack of knowledge and awareness, lack of legislative framework to guide advance care planning implementation and lack of strong initiatives at a national level.

    CONCLUSIONS: It is evident that there is much to learn nationally and internationally about ACP before any decision on implementation of ACP is made in Malaysia. ACP is a public health issue and requires concerted effort of all stakeholders, including Government agencies, academic institutions, and non-government organizations to raise public awareness. More research is needed to shape the future direction of ACP development in Malaysia.

    This study is a continuation of previous research work conducted by the author on the stability of man-made slope constructed in UPNM campus. This paper presents the effects of ground water level (GWL) fluctuation on slope stability by using numerical simulation program, SlopeW. Ground water rises were simulated from 5m below the ground until 10m above the ground. Soil samples were taken from the site and tested in laboratory and then were incorporated into the program. It was found that the stability of the slope decreased with an increase of GWL. The critical slip surface formed by each case study is categorised as toe failure with circular and non-circular shapes.

    Privacy has always been a constant concern for many people. Internet users are often worried about the browsing information that is left on their storage media. Web browsers were later introduced with a new feature called private browsing to overcome this issue. The private browsing mode is expected to behave as normal browsing session but without storing any data such as browser cookies, history, cache and passwords on the local machine. Unfortunately, previous researchers concluded web browser often failed to provide the intended privacy protection to their user. Along the way of this reviewing process, the weakness and downside of previous web browser vendors have been identified.

    Partial discharge (PD) is a phenomenon that may lead to dielectric breakdown and can provide important information for condition monitoring on electrical power equipment, in particular transformer. One of the methods is the detection of the electromagnetic (EM) wave signal emitted by PD. Although the frequency spectrum in EM is very wide, this paper discusses the detection of EM only at ultra-high frequency (UHF). One of the detectors that can be used to detect EM is the antenna. There are a lot of antenna designs that have been proposed to detect the signal. The designs can be generally divided into two: PCB-based design and physical antenna design. An example of the latter is monopole. Some of the proposed antennas were left at the design stage while others went to be applied in actual PD experimentation. Discussion on the capabilities of these antennas can lead to the selection of a suitable antenna.

    Awareness of occupational noise and its effects is growing. At No. 11 squadron base, Sukhoi jet was identified as the main culprit of occupational noise that affects not just the employees of the base but also civilian people in the surrounding area. The objective of the study is to identify the noise level produced by Sukhoi two-engines jet during maintenance operations. Investigations were carried out using Bruel & Kjaer 2250 sound level meter hand-analyser. Measurements were performed directly under the Sukhoi jet body and then 10 metres, 50 metres, 100 metres, 1000 metres and 1500 metres away. The jet engines could operate at two levels, at 72% RPM and at 85% RPM. The civilians are only exposed to its noise from more than 1000 metres away. The results from this study are analysed and noise mapping and noise contouring are produced which give the level of noise exposure. The maximum noise is recorded t 122dB(A) and the minimum is at 60dB(A). The farther the noise from the jet is measured, the lower the values recorded. From the noise mapping, the effects of noise exposures on both the employees at the base and the civilian at the neighbouring surrounding could be identified. Even though the exposures are only for 5-10 minutes, it is still considered as a threat

    Assessment of instructors by students is needed for assessing the teaching quality of a lecturer towards achieving the objectives of a course. This paper aims to examine the techniques used in sentiment analysis for assessing the effectiveness of a lecturer’s or a teacher’s teaching style in the learning process at a university or school. In addition, the effectiveness of sentiment analysis techniques in assisting the teaching evaluation process is also discussed. The challenges for assessing the quality of teaching of National Defence University of Malaysia (UPNM) lecturers are also discussed in this paper. The sentiment analysis technology is capable of analysing views or opinions on a matter, regardless of whether they are positive or negative. Data from the sentiment analysis can be used by specific parties or anyone else to rectify any weakness or to improve any aspect that the user commented on. The purpose of this study is not to find the weakness of the lecturer, but rather the results of this assessment process can be useful to the management for rectifying weaknesses and for improving the teaching process.
