  1. Dynamic Changes in Health-Promoting Properties and Eating Quality During Off-Vine Ripening of Tomatoes
    Siddiqui MW, Lara I, Ilahy R, Tlili I, Ali A, Homa F, et al.
    Compr Rev Food Sci Food Saf, 2018 Nov;17(6):1540-1560.
    PMID: 33350145 DOI: 10.1111/1541-4337.12395
    Tomato (Solanum lycopersicon L.) fruit is rich in various nutrients, vitamins and health-promoting molecules. Fresh tomatoes are an important part of the Mediterranean gastronomy, and their consumption is thought to contribute substantially to the reduced incidence of some chronic diseases in the Mediterranean populations in comparison with those of other world areas. Unfortunately, tomato fruit is highly perishable, resulting in important economic losses and posing a challenge to storage, logistic and supply management. This review summarizes the current knowledge on some important health-promoting and eating quality traits of tomato fruits after harvest and highlights the existence of substantial cultivar-to-cultivar variation in the postharvest evolution of the considered traits according to maturity stage at harvest and in response to postharvest manipulations. It also suggests the need for adapting postharvest procedures to the characteristics of each particular genotype to preserve the optimal quality of the fresh product.

  2. Fulltext COVID-19 outbreak and sectoral performance of the Australian stock market: An event study analysis
    Alam MM, Wei H, Wahid ANM
    Aust Econ Pap, 2020 Nov 27.
    PMID: 33349733 DOI: 10.1111/1467-8454.12215
    The outbreak of COVID-19 has weakened the economy of Australia and its capital market since early 2020. The overall stock market has declined. However, some sectors become highly vulnerable while others continue to perform well even in the crisis period. Given this new reality, we seek to investigate the initial volatility and the sectoral return. In this study, we analyse data for eight sectors such as, transportation, pharmaceuticals, healthcare, energy, food, real estate, telecommunications and technology of the Australian stock market. In doing so, we obtain data from Australian Securities Exchange (ASX) and analysed them based on 'Event Study' method. Here, we use the 10-days window for the event of official announcement of the COVID-19 outbreak in Australia on 27 February 2020. The findings of the study show that on the day of announcement, the indices for food, pharmaceuticals and healthcare exhibit impressive positive returns. Following the announcement, the telecommunications, pharmaceuticals and healthcare sectors exhibit good performance, while poor performance is demonstrated by the transportation industry. The findings are vital for investors, market participants, companies, private and public policymakers and governments to develop recovery action plans for vulnerable sectors and enable investors to regain their confidence to make better investment decisions.

  3. Fulltext Comparison of Knowledge, Attitude, and Practice among Communities Living in Hotspot and Non-Hotspot Areas of Dengue in Selangor, Malaysia
    Ghani NA, Shohaimi S, Hee AK, Chee HY, Emmanuel O, Alaba Ajibola LS
    Trop Med Infect Dis, 2019 Feb 15;4(1).
    PMID: 30781369 DOI: 10.3390/tropicalmed4010037
    BACKGROUND: Dengue has affected more than one-third of the world population and Malaysia has recorded an increase in the number of dengue cases since 2012. Selangor state recorded the highest number of dengue cases in Malaysia. Most of the dengue infections occur among people living in hotspot areas of dengue. This study aims to compare Knowledge, Attitude, and Practice among communities living in hotspot and non-hotspot dengue areas.

    METHOD: Communities living in 20 hotspot and 20 non-hotspot areas in Selangor were chosen in this study where 406 participants were randomly selected to answer questionnaires distributed at their housing areas. Total marks of each categories were compared using t-test.

    RESULT: Results show that there were significant mean differences in marks in Knowledge (p value: 0.003; 15.41 vs. 14.55) and Attitude (p value: < 0.001; 11.41 vs. 10.33), but not Practice (p value 0.101; 10.83 vs. 10.47) categories between communities of non-hotspot and hotspot areas. After considering two confounding variables which are education level and household income, different mean marks are found to be significant in Knowledge when education level acts as a covariate and Attitude when both act as covariates.

    CONCLUSION: Overall results show that people living in non-hotspot areas had better knowledge and attitude than people living in hotspot areas, but no difference was found in practice. This suggests that public health education should be done more frequently with people with a low education background and low household income, especially in hotspot areas to fight dengue outbreak and make dengue cases decrease effectively.

    Asthma is a chronic inflammatory disease of the airway which is often misdiagnosed and undertreated. Early diagnosis and vigilant asthma control are crucial to preventing permanent airway damage, improving quality of life and reducing healthcare burdens. The key approaches to asthma management should include patient empowerment through health education and self-management and, an effective patient-healthcare provider partnership.

  5. The scope for primary prevention of coronary heart disease in Malaysia
    Quek DKL
    Family Practitioner, 1988;11(1):90-91.
    Cardiovascular disease has been the premier cause of hospital-registered deaths in Malaysia for the past 8 years. Among these reported deaths, 31% were caused by coronary heart disease in 1982. A healthy lifestyle to control the coronary risk factors would help to reduce the incidence of coronary heart disease in future.

  7. Linkage analysis and whole exome sequencing reveals AHNAK2 as a novel genetic cause for autosomal recessive CMT in a Malaysian family
    Tey S, Shahrizaila N, Drew AP, Samulong S, Goh KJ, Battaloglu E, et al.
    Neurogenetics, 2019 08;20(3):117-127.
    PMID: 31011849 DOI: 10.1007/s10048-019-00576-3
    Charcot-Marie-Tooth (CMT) disease is a form of inherited peripheral neuropathy that affects motor and sensory neurons. To identify the causative gene in a consanguineous family with autosomal recessive CMT (AR-CMT), we employed a combination of linkage analysis and whole exome sequencing. After excluding known AR-CMT genes, genome-wide linkage analysis mapped the disease locus to a 7.48-Mb interval on chromosome 14q32.11-q32.33, flanked by the markers rs2124843 and rs4983409. Whole exome sequencing identified two non-synonymous variants (p.T40P and p.H915Y) in the AHNAK2 gene that segregated with the disease in the family. Pathogenic predictions indicated that p.T40P is the likely causative allele. Analysis of AHNAK2 expression in the AR-CMT patient fibroblasts showed significantly reduced mRNA and protein levels. AHNAK2 binds directly to periaxin which is encoded by the PRX gene, and PRX mutations are associated with another form of AR-CMT (CMT4F). The altered expression of mutant AHNAK2 may disrupt the AHNAK2-PRX interaction in which one of its known functions is to regulate myelination.

  8. Parkinson's disease and the gastrointestinal microbiome
    Lubomski M, Tan AH, Lim SY, Holmes AJ, Davis RL, Sue CM
    J Neurol, 2020 Sep;267(9):2507-2523.
    PMID: 31041582 DOI: 10.1007/s00415-019-09320-1
    Recently, there has been a surge in awareness of the gastrointestinal microbiome (GM) and its role in health and disease. Of particular note is an association between the GM and Parkinson's disease (PD) and the realisation that the GM can act via a complex bidirectional communication between the gut and the brain. Compelling evidence suggests that a shift in GM composition may play an important role in the pathogenesis of PD by facilitating the characteristic ascending neurodegenerative spread of α-synuclein aggregates from the enteric nervous system to the brain. Here, we review evidence linking GM changes with PD, highlighting mechanisms supportive of pathological α-synuclein spread and intestinal inflammation in PD. We summarise existing patterns and correlations seen in clinical studies of the GM in PD, together with the impacts of non-motor symptoms, medications, lifestyle, diet and ageing on the GM. Roles of GM modulating therapies including probiotics and faecal microbiota transplantation are discussed. Encouragingly, alterations in the GM have repeatedly been observed in PD, supporting a biological link and highlighting it as a potential therapeutic target.

  9. Fulltext The Role of MicroRNAs in Lung Cancer Metabolism
    Azizi MIHN, Othman I, Naidu R
    Cancers (Basel), 2021 Apr 05;13(7).
    PMID: 33916349 DOI: 10.3390/cancers13071716
    MicroRNAs (miRNAs) are short-strand non-coding RNAs that are responsible for post-transcriptional regulation of many biological processes. Their differential expression is important in supporting tumorigenesis by causing dysregulation in normal biological functions including cell proliferation, apoptosis, metastasis and invasion and cellular metabolism. Cellular metabolic processes are a tightly regulated mechanism. However, cancer cells have adapted features to circumvent these regulations, recognizing metabolic reprogramming as an important hallmark of cancer. The miRNA expression profile may differ between localized lung cancers, advanced lung cancers and solid tumors, which lead to a varying extent of metabolic deregulation. Emerging evidence has shown the relationship between the differential expression of miRNAs with lung cancer metabolic reprogramming in perpetuating tumorigenesis. This review provides an insight into the role of different miRNAs in lung cancer metabolic reprogramming by targeting key enzymes, transporter proteins or regulatory components alongside metabolic signaling pathways. These discussions would allow a deeper understanding of the importance of miRNAs in tumor progression therefore providing new avenues for diagnostic, therapeutic and disease management applications.

  10. Proteomic Investigations of In Vitro and In Vivo Models of Periodontal Disease
    Binti Badlishah Sham NI, Lewin SD, Grant MM
    Proteomics Clin Appl, 2020 05;14(3):e1900043.
    PMID: 31419032 DOI: 10.1002/prca.201900043
    Proteomics has currently been a developing field in periodontal diseases to obtain protein information of certain samples. Periodontal disease is an inflammatory disorder that attacks the teeth, connective tissues, and alveolar bone within the oral cavity. Proteomics information can provide proteins that are differentially expressed in diseased or healthy samples. This review provides insight into approaches researching single species, multi species, bacteria, non-human, and human models of periodontal disease for proteomics information. The approaches that have been taken include gel electrophoresis and qualitative and quantitative mass spectrometry. This review is carried out by extracting information about in vitro and in vivo studies of proteomics in models of periodontal diseases that have been carried out in the past two decades. The research has concentrated on a relatively small but well-known group of microorganisms. A wide range of models has been reviewed and conclusions across the breadth of these studies are presented in this review.

  11. Dietary phytochemicals that influence gut microbiota: Roles and actions as anti-Alzheimer agents
    Wang Y, Lim YY, He Z, Wong WT, Lai WF
    Crit Rev Food Sci Nutr, 2021 Feb 09.

    The last decide has witnessed a growing research interest in the role of dietary phytochemicals in influencing the gut microbiota. On the other hand, recent evidence reveals that dietary phytochemicals exhibit properties of preventing and tackling symptoms of Alzheimer's disease, which is a neurodegenerative disease that has also been linked with the status of the gut microbiota over the last decade. Till now, little serious discussions, however, have been made to link recent understanding of Alzheimer's disease, dietary phytochemicals and the gut microbiota together and to review the roles played by phytochemicals in gut dysbiosis induced pathologies of Alzheimer's disease. Deciphering these connections can provide insights into the development and future use of dietary phytochemicals as anti-Alzheimer drug candidates. This review aims at presenting latest evidence in the modulating role of phytochemicals in the gut microbiota and its relevance to Alzheimer's disease and summarizing the mechanisms behind the modulative activities. Limitations of current research in this field and potential directions will also be discussed for future research on dietary phytochemicals as anti-Alzheimer agents.

  12. Fulltext Sane and safe: Forced social distancing to prevent human-to-human transmission of COVID-19
    Jahan F
    Malays Fam Physician, 2021 Mar 25;16(1):15-17.
    PMID: 33948138 DOI: 10.51866/rv0001
    The current outbreak of COVID-19, originating from the city of Wuhan in China and ultimately involving over 200 countries, is now a global concern. Evidence indicates that COVID-19 spread to humans from wild animals, causing severe respiratory tract infections in humans; the typical symptoms of COVID include cough, high-grade fever, sore throat, and difficulty in breathing. The infection spreads from human to human via droplets. Therefore, social or physical distancing can reduce spread within communities. Asymptomatic spread can also occur during family gatherings or in the workplace; thus, we must enforce physical distancing as much as possible to reduce the spread of cases.

  13. Fulltext Occurrence of Recurrent Aphthous Stomatitis (RAS) as a Rare Oral Manifestation in a Patient with Gilbert's Syndrome
    Heboyan A, Avetisyan A, Skallevold HE, Rokaya D, Marla V, Vardanyan A
    Case Rep Dent, 2021;2021:6648729.

    Recurrent aphthous stomatitis is an ulcerative disease of the oral cavity and can occur in isolation or as a manifestation of many systemic diseases. It is a quite common entity and may hence often be overlooked as an isolated lesion. Gilbert's syndrome is a genetic disorder where a deficiency of an enzyme associated with the conjugation of bilirubin results in unconjugated hyperbilirubinemia. The disease is generally asymptomatic and is aggravated by certain trigger factors. No associated oral manifestations are known. In this case report, we discuss the concomitant presence of recurrent aphthous stomatitis in a patient of Gilbert's syndrome. The presence of such recurrent stomatitis may represent as an oral manifestation of Gilbert's syndrome. Early identification of these entities may improve the overall quality of life of the patient.

  14. Hemophilia treatment in developing countries: products and protocols
    Srivastava A, You SK, Ayob Y, Chuansumrit A, de Bosch N, Perez Bianco R, et al.

    The most important aspect of management of hemophilia is to provide adequate replacement of safe clotting factor concentrates to prevent or treat bleeding episodes. There has been considerable progress in many countries in the developing world with regard to this aspect of care. However, very little data are available in the literature on the types of products being used for factor replacement and the doses being administered for control or treatment of bleeding in different countries. These data are important to document because only then can data from different centers be compared. This article provides data from seven countries: Korea, Malaysia, Thailand, Venezuela, Argentina, Iran, and India. It shows that there is wide variability not only in the types of products used (plasma to recombinant factor concentrates) but also in the doses administered (minimal to very high) for similar indications. Prospective documentation of data on musculoskeletal outcome at these centers and correlation with dose of factor replacement could help identify different models of care. Comparing such data and collating the experience in different countries could be useful for optimizing care and establishing cost-effective models. The combined experience in the developing world in providing hemophilia services should be used to define standards of care that are practical and to set achievable goals.

  15. Fulltext Capsule endoscopy in inflammatory bowel disease: when and how
    Hilmi I, Kobayashi T
    Intest Res, 2020 Jul;18(3):265-274.
    PMID: 32623876 DOI: 10.5217/ir.2019.09165
    Capsule endoscopy (CE) is emerging as an important investigation in inflammatory bowel disease (IBD); common types include the standard small bowel CE and colon CE. More recently, the pan-enteric CE was developed to assess the large and small bowel in patients with Crohn's disease (CD). Emerging indications include noninvasive assessment for mucosal healing (both in the small bowel and the colon) and detection of postoperative recurrence in patients with CD. Given the increasing adoption, several CE scoring systems have been specifically developed for IBD. The greatest concern with performing CE, particularly in CD, is capsule retention, but this can be overcome by performing cross-sectional imaging such as magnetic resonance enterography and using patency capsules before performing the procedure. The development of software for automated detection of mucosal abnormalities typically seen in IBD may further increase its adoption.

    The World Health Organisation Western Pacific Region countries were declared free of polio in 2000 until a polio outbreak involving 305 cases occurred in Indonesia in 2006. It was not until 2014 that the World Health Organisation South East Asia region was officially declared polio-free again. However, in February 2019, the Global Polio Eradication Initiative announced a new circulating vaccine-derived poliovirus outbreak in the Papua province of Indonesia. To make matter worse, the outbreak responses were tardy and led to transmission among migrating communities to other cities. The pressing regional issues of polio outbreak caused by circulating vaccine-derived poliovirus and use of oral polio vaccine have not been well presented. Our letter highlighted the suboptimal outbreak responses as well as the necessity of cross-border vaccination to curb continued poliovirus transmission.

    Prurigo nodularis (PN) is an uncommon skin condition known to be associated with underlying systemic diseases. This case report is about PN secondary to underlying Hodgkin’s lymphoma. A 30-year-old man presented with this skin condition three months before lymphadenopathy and systemic symptoms due to lymphoma. He had made multiple visits to general practitioners for the disturbing rash, given multiple courses of topical treatment without relief. His PN showed marked improvement after initiation of chemotherapy. This case reminds that an unexplained skin condition should prompt clinicians for investigating for an underlying systemic disease. This case, to our knowledge, is the first Hodgkin’s lymphoma-associated prurigo nodularis reported in Malaysia.

  18. Fulltext Unravelling the myths of R0 in controlling the dynamics of COVID-19 outbreak: A modelling perspective

    Chaos Solitons Fractals, 2020 Sep;138:109943.

    COVID-19 is an emerging and rapidly evolving pandemic around the world, which causes severe acute respiratory syndrome and results in substantial morbidity and mortality. To examine the transmission dynamics of COVID-19, we investigate the spread of this pandemic using Malaysia as a case study and scrutinise its interactions with some exogenous factors such as limited medical resources and false detection problems. To do this, we employ a simple epidemiological model and analyse this system using modelling and dynamical systems techniques. We discover some contrasting findings with respect to the observations of basic reproduction number: while it is observed that R0 seems to provide a good description of transmission dynamics in simple outbreak scenarios, this quantity might mislead the assessment on the severity of pandemic when certain complexities such as limited medical resources and false detection problems are incorporated into the model. In particular, we observe the possibility of a COVID-19 outbreak through bistable behaviour, even when the basic reproduction number is less than unity. Based on these findings, we caution policy makers not to make their decisions solely based on the guidance of the basic reproduction number only, which clearly could cause trouble.

  19. Fulltext Acute pancreatitis with electrocardiographic changes mimicking acute coronary syndrome: a diagnostic conundrum
    Shamala N., Faizal, A.H.
    Medicine & Health, 2018;13(2):195-201.
    MyJurnal
    Electrocardiographic abnormalities can be associated with acute pancreatitis. However, data regarding the actual causative factor still remains elusive. Many previous cases were reported on non-specific ST and T wave abnormalities concurrent with acute pancreatitis but rarely with an increasing trend of cardiac markers. We describe the case of a 70-year-old female who presented with one such conundrum. Our patient had typical presentation of acute pancreatitis but had dynamic ECG changes with markedly increased cardiac markers. Subsequently after initiation of treatment for acute pancreatitis and observation for the course of several days, the ECG returned to the baseline as pre admission. This substantiates the fact that acute pancreatitis can mimic both biochemical and electrical manifestation of an acute coronary syndrome. Thus, Emergency Physicians should consider acute pancreatitis as a possible diagnosis in patients who present with abnormal electrocardiograms.

    In this article, data on the demographic parameters of the Aedes albopictus were collected from those areas in Shah Alam, Malaysia that had experienced a dengue outbreak. The surveys were conducted from March to December 2017. The eggs of the Ae. albopictus were collected using ovitraps, and were analysed based on the demographic parameters in a controlled environment in an insectarium. The data were comprised of four types of biological information on the life demographic parameters of the Ae. albopictus that were monitored based on specific localities. The data were inferred information regarding egg productivity (n), egg development (%), immature development (days), and survivorship (days).
