    OBJECTIVE: To disseminate the portable sequencer MinION in developing countries for the main purpose of battling infectious diseases, we found a consortium called Global Research Alliance in Infectious Diseases (GRAID). By holding and inviting researchers both from developed and developing countries, we aim to train the participants with MinION's operations and foster a collaboration in infectious diseases researches. As a real-life example in which resources are limited, we describe here a result from a training course, a metagenomics analysis from two blood samples collected from a routine cattle surveillance in Kulan Progo District, Yogyakarta Province, Indonesia in 2019.

    RESULTS: One of the samples was successfully sequenced with enough sequencing yield for further analysis. After depleting the reads mapped to host DNA, the remaining reads were shown to map to Theileria orientalis using BLAST and OneCodex. Although the reads were also mapped to Clostridium botulinum, those were found to be artifacts derived from the cow genome. An effort to construct a consensus sequence was successful using a reference-based approach with Pomoxis. Hence, we concluded that the asymptomatic cow might be infected with T. orientalis and showed the usefulness of sequencing technology, specifically the MinION platform, in a developing country.

    PMID: 32173662 DOI: 10.4265/bio.25.1
    Aquaculture is developing so fast that infectious disease outbreak happens regularly. Antibiotic treatment results in development of antibiotic resistance pathogens, thus cause urgent action in searching of other alternative treatment method. Postbiotic was one of the explored strategies among various proposed alternatives. Due to its benefits in agriculture industry, it may be useful in aquaculture industry. Although many reviews were reported on other alternative strategies, the review on postbiotic in aquaculture is limited. This mini review provides an overview of different postbiotics as aquaculture disease control agents. Peptides and exopolysaccharides have antimicrobial properties against bacterial pathogens. Then, short chain fatty acids have both antimicrobial activities against bacterial pathogens and immunostimulating effects to aquatic organism. Vitamins, peptidoglycan and lipopolysaccharide are reported as immunostimulants. Finally, cell surface proteins and teichoic acid can act as vaccine.

    In an aim of developing portable biosensor for SARS-CoV-2 pandemic, which facilitates the point-of-care aptasensing, a strategy using 10 μm gap-sized gold interdigitated electrode (AuIDE) is presented. The silane-modified AuIDE surface was deposited with ∼20 nm diamond and enhanced the detection of SARS-CoV-2 nucleocapsid protein (NCP). The characteristics of chemically modified diamond were evidenced by structural analyses, revealing the cubic crystalline nature at (220) and (111) planes as observed by XRD. XPS analysis denotes a strong interaction of carbon element, composed ∼95% as seen in EDS analysis. The C-C, CC, CO, CN functional groups were well-refuted from XPS spectra of carbon and oxygen elements in diamond. The interrelation between elements through FTIR analysis indicates major intrinsic bondings at 2687-2031 cm-1. The aptasensing was evaluated through electrochemical impedance spectroscopy measurements, using NCP spiked human serum. With a good selectivity the lower detection limit was evidenced as 0.389 fM, at a linear detection range from 1 fM to 100 pM. The stability, and reusability of the aptasensor were demonstrated, showing ∼30% and ∼33% loss of active state, respectively, after ∼11 days. The detection of NCP was evaluated by comparing anti-NCP aptamer and antibody as the bioprobes. The determination coefficients of R2 = 0.9759 and R2 = 0.9772 were obtained for aptamer- and antibody-based sensing, respectively. Moreover, the genuine interaction of NCP aptamer and protein was validated by enzyme linked apta-sorbent assay. The aptasensing strategy proposed with AuIDE/diamond enhanced sensing platform is highly recommended for early diagnosis of SARS-CoV-2 infection.

    Lim BN, Tye GJ, Choong YS, Ong EB, Ismail A, Lim TS
    Biotechnol Lett, 2014 Dec;36(12):2381-92.
    PMID: 25214212 DOI: 10.1007/s10529-014-1635-x
    Antibodies have been used efficiently for the treatment and diagnosis of many diseases. Recombinant antibody technology allows the generation of fully human antibodies. Phage display is the gold standard for the production of human antibodies in vitro. To generate monoclonal antibodies by phage display, the generation of antibody libraries is crucial. Antibody libraries are classified according to the source where the antibody gene sequences were obtained. The most useful library for infectious diseases is the immunized library. Immunized libraries would allow better and selective enrichment of antibodies against disease antigens. The antibodies generated from these libraries can be translated for both diagnostic and therapeutic applications. This review focuses on the generation of immunized antibody libraries and the potential applications of the antibodies derived from these libraries.

    Hong, Eric Qiu Weng, Cheo, Seng Wee, Low, Qin Jian
    Borneo Journal of Medical Sciences, 2021;15(1):57-60.
    MyJurnal
    Dengue and malaria infections are common mosquito-borne infectious diseases in tropical and subtropical regions. The clinical manifestations of dengue and malaria often mimic each other, causing the predicament of early diagnosis without laboratory investigations. Concurrent dengue and malaria infection are often rare scenarios when both diseases occur in a particular patient at the same time. A high index of suspicion is therefore required to establish an early diagnosis to ensure complete success in its management. This case report is about concurrent dengue and malaria infection in a 54-year-old Pakistani man who presented with high-grade fever for three days before admission. On examination, he was febrile (38.8°C) with no other findings. His blood investigations were positive for NS1 antigen and IgM but negative for IgG. His peripheral blood film revealed the presence of Plasmodium vivax. He was treated for dengue fever with supportive management and started with oral Riamet (artemether and lumefantrine) along with oral primaquine 30 mg daily for two weeks’ duration. Following treatment, the patient demonstrated progressive clinical improvement and was subsequently discharged back to the community clinic for the continuation of care.

    MyJurnal
    Dengue fever and its fatal complications have made a comeback since its control in the 1990’s. The Flavivirus has evolved into 4 serotypes DEN 1,2,3,4 which can be passed on by the mosquitoes for 7 generations for each serotype. This communicable disease is predominantly confined to urban areas. Quick control of the spread of the disease will prevent it from becoming an epidemic. The two species mosquitoes involved have different behaviours. The Aedes aegypti is an indoor vector which breeds in clean, clear and calm freshwater. The Aedes albopictus is an outdoor breeding mosquito which breeds in stagnant waters. Surveillance of the areas prone to outbreaks is vital. One of the roles of the entomologist is to monitor the vector for resistance to the insecticides. Localities that have been subjected to recurrent outbreaks will have vector which develop resistance to the insecticides used.

    Infectious disease remains a public health concern in Malaysia. Efficient public health infectious disease surveillance is needed in order to address the issues posed by infectious disease. The main goal of public health infectious disease surveillance is to facilitate the control and prevention of the infectious diseases. For that, infectious disease surveillance needs involvement of multidiscipline either in government or non-government/private to ensure its success. General practitioners (GPs) have an important role in public health infectious disease surveillance considering their role and position as one of the main front liner medical personnel.

    PMID: 16223373
    At this moment, public health authorities, physicians and scientists around the world are struggling to cope with a severe and rapidly spreading new disease in humans called severe acute respiratory syndrome, or SARS. According to World Health Organisation (WHO) this appears to be the first severe and easily transmissible new disease to emerge in the 21st century. Though much about the disease remains poorly understood, including the details of the causative virus, we do know that it has features that allow it to spread rapidly along international air travel routes. As of 10 May 2003, a cumulative 7296 probable SARS cases with 526 deaths have been reported from 30 countries on three continents (WHO, ProMED). In the past week, more than 1000 new probable cases and 96 deaths were reported globally. This represents an increase of 119 new cases and 8 new deaths compared with 9 May 2003 (China (85), Taiwan (23), and Hong Kong (7) represented the overwhelming majority, with one additional case each reported from France, Malaysia, Singapore, and the United States). Only in China, as of 10 May 2003 (WHO) total of 4884 with 235 deaths have been reported. Some outbreaks have reassuring features.

  12. Health imperatives in foreign policy: the case of Malaysia
    Barraclough S, Phua KL
    Bull World Health Organ, 2007 Mar;85(3):225-9.
    PMID: 17486215
    Malaysia's global, regional and bilateral international health relations are surveyed against the historical backdrop of the country's foreign policy. Malaysia has always participated in multilateral agencies, most notably the World Health Organization, as such agencies are part of the longstanding fabric of "good international citizenship". The threats of infectious diseases to human health and economic activity have caused an intensification and an organizational formalization of Malaysian health diplomacy, both regionally and bilaterally. Such diplomacy has also established a basis for developing a wider set of cooperative relationships that go beyond responding to the threat of pandemics. As Malaysia approaches "developed" status, its health sector is becoming increasingly integrated into the global economy through joint research and development ventures and transnational investment. At the same time, it will have the technological, financial and human resources to play an expanded altruistic role in global and regional health.

    Mardhiah K, Wan-Arfah N, Naing NN, Abu Hassan MR, Chan HK, Hasan H
    Clinicoecon Outcomes Res, 2021;13:155-162.
    PMID: 33732004 DOI: 10.2147/CEOR.S286283
    Purpose: This study was conducted to determine the direct medical cost of treating melioidosis patients. The calculation was made according to the variables extracted from medical records.

    Materials and Methods: Data collection was performed retrospectively on a total of 293 cases from Hospital Sultanah Bahiyah, Kedah, Malaysia. The data consisted of personal information, treatment history, and investigation findings, including blood results, USG abdomen results, and CT scan results. The site of culture and sensitivity were also obtained. The total direct medical cost was based on the antibiotics/treatments received by the patients, diagnostic test and investigations performed. The trend analysis used to see the pattern of costs from 2014 to 2017. All the costs were compared based on patients' status and duration of stay at the hospital using the independent t-test.

    Results: The overall mean of direct medical cost for melioidosis amounted to US $233.61 (RM931.33). Overall, the finding confirms a huge reduction (44.7%) of direct medical cost from 2014 to 2017 (P = 0.001). From 2015 to 2016, there was a 19.1% reduction of direct medical cost (P>0.95), followed by a 38.8% reduction in costs from 2016 to 2017 (P = 0.019). In the case of the duration of stay, the mean of total direct medical cost among patients with ≥14 duration of stay was higher compared to those with <14 duration of stay (p < 0.001). There was no significant mean difference of direct medical cost between patients who were cured and died.

    Conclusion: Despite the higher mortality of melioidosis cases compared to other infectious diseases, there is a limitation in the amount of published data on the management cost of melioidosis. The importance of cost in managing this disease should be underlined to perform a fully prepared management toward the disease.

    In recent biomedical research, the area of cancer and infectious diseases has a leading position in the utilization of medicinal plants as a source of drug discovery. Malaysia has a diversity and a large number of underutilized fruits that are rich in phenolic compounds. Artoarpus altilis consider an underutilized fruit that is rich in phenolic compounds. Methanol extracts of A. altilis have been previously found to contain a high content of antioxidant phytochemicals. The purpose of the study was to evaluate the cytotoxicity and toxicological effect of methanol fruit extracts against MCF-7 cells. To determine the least concentration that might kill or suppress the growth of the cancer cells was in a concentration-dependent manner approach. The variation in the cytotoxic activity among the extracts was indicated by determining the IC50 of each extract against cells at 72 h. The IC50 of the samples was measured using a trypan blue exclusion assay. The methanol extract of the pulp part showed the least inhibition concentration of 15.40±0.91 μg/mL on MCF-7 cells. In the study, the molecular mechanism of methanol extracts-induced apoptosis and cell cycle arrested in human cancer cells were investigated in a time-dependent-manners approach by using flow cytometry. The treated cells were stained with nexin to detect early and late apoptosis and with propidium iodide (PI) for cell cycle arrest associated with the DNA fragmentation, various cell arrests occurred at G1/S, S, and G2/M phases. Lastly, the gene expression analysis by (RT-qPCR) method was carried out by analyzing the expression of the gene of interest for the quantification of mRNA levels. Results after cells treated with IC50 were revealed by upregulating anti-apoptotic genes/downregulated of pro-apoptotic BCL-2 gene expressions were triggered the treated cells into CASPASE-3, intrinsic and extrinsic pathways. These findings suggest that the methanol extracts of three parts of A. altilis fruit have potential anticancer activity against MCF-7 cells mainly the pulp part of the fruit.

    Developing new treatments for emerging infectious diseases in infectious and noninfectious diseases has attracted a particular attention. The emergence of viral diseases is expected to accelerate; these data indicate the need for a proactive approach to develop widely active family specific and cross family therapies for future disease outbreaks. Viral disease such as pneumonia, severe acute respiratory syndrome type 2, HIV infection, and Hepatitis-C virus can cause directly and indirectly cardiovascular disease (CVD). Emphasis should be placed not only on the development of broad-spectrum molecules and antibodies but also on host factor therapy, including the reutilization of previously approved or developing drugs. Another new class of therapeutics with great antiviral therapeutic potential is molecular communication networks using deep learning autoencoder (DL-AEs). The use of DL-AEs for diagnosis and prognosis prediction of infectious and noninfectious diseases has attracted a particular attention. MCN is map to molecular signaling and communication that are found inside and outside the human body where the goal is to develop a new black box mechanism that can serve the future robust healthcare industry (HCI). MCN has the ability to characterize the signaling process between cells and infectious disease locations at various levels of the human body called point-to-point MCN through DL-AE and provide targeted drug delivery (TDD) environment. Through MCN, and DL-AE healthcare provider can remotely measure biological signals and control certain processes in the required organism for the maintenance of the patient's health state. We use biomicrodevices to promote the real-time monitoring of human health and storage of the gathered data in the cloud. In this paper, we use the DL-based AE approach to design and implement a new drug source and target for the MCN under white Gaussian noise. Simulation results show that transceiver executions for a given medium model that reduces the bit error rate which can be learned. Then, next development of molecular diagnosis such as heart sounds is classified. Furthermore, biohealth interface for the inside and outside human body mechanism is presented, comparative perspective with up-to-date current situation about MCN.

    Acute mastoiditis in a newborn complicated by the presence of facial nerve palsy is an alarming finding requiring rapid assessment and further investigation. Such an early presentation should point the clinician towards an underlying systemic pathology or congenital anatomical abnormality. Facial nerve involvement indicates severe infection and possible dehiscence of the facial canal. Although more frequent in children, it is rare in neonates. We would like to share our experience in managing the youngest known presentation of otomastoiditis at four days of life. The patient presented with otorrhea and facial paralysis and progressed to meningitis. He was finally diagnosed with chronic granulomatous disease.

    PMID: 33842136 DOI: 10.7759/cureus.13760
    Melioidosis is an infectious disease most commonly found in places with tropical climates. Definitive diagnosis can be confirmed by culture or pathological results of blood or infected organ. However, imaging study is helpful in providing early provisional diagnosis and guiding therapy. Point-of-care ultrasound can be currently performed bedside by non-radiological staff such as emergency physicians or intensivists. We present the case of a pediatric patient who got diagnosed with melioidosis after detection of multiple splenic and hepatic abscesses by point-of-care ultrasound, leading to early diagnosis and appropriate empirical antibiotic selection, resulting in good treatment outcome.

    ESTEEM Academic Journal, 2020;16(1):15-26.
    MyJurnal
    Recently consumers are facing the issue of health problems such as Non - Communicable Disease (NCD) occurring in the society due to unhealthy lifestyle and behaviours. Consumers have claimed that they have knowledge about nutrition information but with low awareness level to read the
    nutrition information and difficulties to interpret the nutrition information on the food label. The nutrition contained in the food has been presented in numerical data and unattractive design. Plus, the rush when shopping will make the consumers neglect to read the food label. This research attempted to focus on the development of a suitable and usable nutrition pictograph design as a tool to educate the consumers in choosing a healthier selection of packed food. The researchers used the Delphi Technique as a medium in choosing the appropriate nutrition pictograph design, which should be incorporated into the selected food label. Findings from this study revealed positive feedback and reached a consensus, and all expert panels have agreed on the development of the nutrition pictogram design. Therefore, the implication of this study is targeted towards the consumers, Ministry of Health and food manufacturers. It can also contribute to the growth of the Visual Communication field. This nutrition pictograph design is intended to educate and inculcate the consumers and enhance health awareness in selecting the healthier choice of food.

  20. Fulltext A Review of Zoonotic Infection Risks Associated with the Wild Meat Trade in Malaysia
    Cantlay JC, Ingram DJ, Meredith AL
    Ecohealth, 2017 Jun;14(2):361-388.
    PMID: 28332127 DOI: 10.1007/s10393-017-1229-x
    The overhunting of wildlife for food and commercial gain presents a major threat to biodiversity in tropical forests and poses health risks to humans from contact with wild animals. Using a recent survey of wildlife offered at wild meat markets in Malaysia as a basis, we review the literature to determine the potential zoonotic infection risks from hunting, butchering and consuming the species offered. We also determine which taxa potentially host the highest number of pathogens and discuss the significant disease risks from traded wildlife, considering how cultural practices influence zoonotic transmission. We identify 51 zoonotic pathogens (16 viruses, 19 bacteria and 16 parasites) potentially hosted by wildlife and describe the human health risks. The Suidae and the Cervidae families potentially host the highest number of pathogens. We conclude that there are substantial gaps in our knowledge of zoonotic pathogens and recommend performing microbial food safety risk assessments to assess the hazards of wild meat consumption. Overall, there may be considerable zoonotic risks to people involved in the hunting, butchering or consumption of wild meat in Southeast Asia, and these should be considered in public health strategies.
