  1. Using tracers to link health services to training through evaluation
    Bandaranayake RC, Singh PJ
    Med Educ, 1993 Nov;27(6):509-17.
    PMID: 8208159
    The tracer concept was applied to evaluate the delivery of family health care and the training of family health workers. A retrospective evaluation permitted linking the products of care to process, input and context, by isolating and analysing potential factors contributing to a limited number of representative concerns. Contributory learning deficiencies identified in health workers, one input to health care as well as a product of training, enabled the evaluation of training programmes to be focused on related segments of the courses. The latter were evaluated through a pathway analysis which followed the same deficiency model as the evaluation of health care. Links were thus established between the traditionally compartmentalized training and service sectors in health.

    One hundred four children with acute lymphoblastic leukaemia were diagnosed at the University Hospital, Kuala Lumpur, Malaysia, between 1976 and 1982; 87 were evaluable with respect to treatment. They were divided into good prognosis (GP) and bad prognosis (BP) groups based on their initial total white cell count, their treatment differing only during the maintenance phase. Remission was achieved in 82 patients (94%) of whom ten (12%) subsequently died in remission from infection. Twenty-eight (34%) relapsed while on treatment and three while off therapy. Eleven patients ceased treatment after 3 yr of continuous complete remission (CCR). Three of these later relapsed, two within the first year. Survival in CCR was significantly better in the GP group up to 30 months, after which the difference diminished. There was no difference in survival between boys and girls. The overall disease-free survival at 3 yr and 5 yr was 40% and 25%, respectively, with a median follow-up period of 20 months (range 4-69 months). The reasons for the relatively low survival rates as compared with those in developed countries are discussed.
  3. Fulltext The impact of satisfaction, and autonomous learning strategies use on scholastic achievement during Covid-19 confinement in Malaysia
    Anthonysamy L, Singh P
    Heliyon, 2023 Feb;9(2):e12198.
    PMID: 36755584 DOI: 10.1016/j.heliyon.2022.e12198
    The purpose of this study is twofold. Firstly, this study seeks to better understand students' learning experience, through scholastic achievement and secondly, this study analyses students' use of autonomous learning strategies, namely satisfaction, self-efficacy, social interactive engagement and study engagement in digital learning amidst the Covid-19 lockdown. While Malaysia grapples with a growing number of Covid-19 cases, the underlying toll of the pandemic has hit the youth hard with many mental health concerns and this has affected their learning. The nurturing of autonomous learning strategies especially during the Covid-19 confinement is critically needed to assist this vulnerable group. Although there is a plethora of studies given students' use of autonomous learning strategies towards scholastic achievement during the Covid-19 lockdown internationally, studies in the Asia region are still rudimentary. This study investigated 316 university students from targeted universities in Malaysia. Responses were gathered from an online survey. Data were analysed using Partial Least Squares-Structural Equation Modelling (PLS-SEM), a second-generation multivariate statistical approach to assess the outer model and inner model that displays the relationships between the constructs. The results of this case study reported that student interactive engagement (β = 0.348, t = 5.45) and study environment (β = 0.314, t = 4.81) have a significant impact on students' scholastic achievement during the lockdown. Remarkably, new insights are uncovered in this paper revealing no relationship between self-efficacy and satisfaction with students' scholastic achievement. Possible explanations surrounding why satisfaction and self-efficacy were suppressed by the lockdown are discussed. The outcomes of this study provide key insights that may assist students to condition their minds to use autonomous learning strategies in digital learning to enhance their scholastic achievement.
  4. The global burden of coeliac disease: opportunities and challenges
    Makharia GK, Singh P, Catassi C, Sanders DS, Leffler D, Ali RAR, et al.
    Nat Rev Gastroenterol Hepatol, 2022 Jan 03.

    Coeliac disease is a systemic disorder characterized by immune-mediated enteropathy, which is caused by gluten ingestion in genetically susceptible individuals. The clinical presentation of coeliac disease is highly variable and ranges from malabsorption through solely extra-intestinal manifestations to asymptomatic. As a result, the majority of patients with coeliac disease remain undiagnosed, misdiagnosed or experience a substantial delay in diagnosis. Coeliac disease is diagnosed by a combination of serological findings of disease-related antibodies and histological evidence of villous abnormalities in duodenal biopsy samples. However, variability in histological grading and in the diagnostic performance of some commercially available serological tests remains unacceptably high and confirmatory assays are not readily available in many parts of the world. Currently, the only effective treatment for coeliac disease is a lifelong, strict, gluten-free diet. However, many barriers impede patients' adherence to this diet, including lack of widespread availability, high cost, cross-contamination and its overall restrictive nature. Routine follow-up is necessary to ensure adherence to a gluten-free diet but considerable variation is evident in follow-up protocols and the optimal disease management strategy is not clear. However, these challenges in the diagnosis and management of coeliac disease suggest opportunities for future research.

    Au MK, Singh P
    Med J Malaysia, 1991 Dec;46(4):329-32.
    PMID: 1840440
    The effect of an antiprostaglandin, piroxicam, in preventing surgically induced miosis is studied. Patients undergoing extracapsular cataract surgery were randomly divided into the piroxicam and placebo groups. Intra-operative measurements of the pupillary diameters were performed. The stages of procedure at which they were measured were at the beginning of operation (Stage 1), after anterior capsulotomy (Stage 2), after lens nucleus delivery (Stage 3) and at the end of irrigation and aspiration (Stage 4). It is noted in this Study that the pupillary diameters were larger at stages 2,3 and 4 in the piroxicam group. The increase in the mean pupillary areas of the piroxicam group were statistically significant for Stages 3 and 4.

  7. Fulltext The Global, Regional, and National Burden of Adult Lip, Oral, and Pharyngeal Cancer in 204 Countries and Territories: A Systematic Analysis for the Global Burden of Disease Study 2019
    GBD 2019 Lip, Oral, and Pharyngeal Cancer Collaborators, Cunha ARD, Compton K, Xu R, Mishra R, Drangsholt MT, et al.
    JAMA Oncol, 2023 Oct 01;9(10):1401-1416.
    PMID: 37676656 DOI: 10.1001/jamaoncol.2023.2960
    IMPORTANCE: Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning.

    OBJECTIVE: To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates.

    EVIDENCE REVIEW: The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019.

    FINDINGS: In 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia.

    CONCLUSIONS AND RELEVANCE: In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts.

  8. Testicular relapse in childhood acute lymphoblastic leukaemia in Malaysia, 1967-82
    Lin HP, Taib NM, Singh P, Sinniah D, Lam KL
    Aust Paediatr J, 1984 Mar;20(1):53-6.
    PMID: 6590027
    From 1967-82, 9 children with testicular relapse (TR) of acute lymphoblastic leukaemia (ALL) were diagnosed out of 99 boys treated, an incidence of 9.1%. The median time from the onset of ALL until diagnosis was 28 months (range 3-41 months). All were asymptomatic; six were detected on routine examination while three were diagnosed only on biopsy. Routine biopsy prior to stopping chemotherapy is useful in detecting occult TR. Biopsies should be done on both the testes regardless of the clinical findings. The age, leucocyte count and hepatosplenomegaly at diagnosis of ALL were not found to be significant factors in influencing relapse. Eight children were in bone marrow remission at the time of TR, but three had preceding or concurrent meningeal leukaemia while in the other five the testis was the first and only site of relapse. Radiotherapy was effective in local disease control but failed to prevent bone marrow relapse in all except two patients despite continuation of chemotherapy. The median time from onset of TR until bone marrow relapse was 7 months (range 3-13 months) and the median time until death, was 11 months (range 6-18 months). The frequency of testicular relapse may be related to the intensity of either the initial induction therapy or the consolidation chemotherapy. Further studies are required to determine whether the incidence of testicular relapse will decline with more intensive early treatment.
  9. Sheath blight of rice: a review and identification of priorities for future research
    Singh P, Mazumdar P, Harikrishna JA, Babu S
    Planta, 2019 Nov;250(5):1387-1407.
    PMID: 31346804 DOI: 10.1007/s00425-019-03246-8
    MAIN CONCLUSION: Rice sheath blight research should prioritise optimising biological control approaches, identification of resistance gene mechanisms and application in genetic improvement and smart farming for early disease detection. Rice sheath blight, caused by Rhizoctonia solani AG1-1A, is one of the most devasting diseases of the crop. To move forward with effective crop protection against sheath blight, it is important to review the published information related to pathogenicity and disease management and to determine areas of research that require deeper study. While progress has been made in the identification of pathogenesis-related genes both in rice and in the pathogen, the mechanisms remain unclear. Research related to disease management practices has addressed the use of agronomic practices, chemical control, biological control and genetic improvement: Optimising nitrogen fertiliser use in conjunction with plant spacing can reduce spread of infection while smart agriculture technologies such as crop monitoring with Unmanned Aerial Systems assist in early detection and management of sheath blight disease. Replacing older fungicides with natural fungicides and use of biological agents can provide effective sheath blight control, also minimising environmental impact. Genetic approaches that show promise for the control of sheath blight include treatment with exogenous dsRNA to silence pathogen gene expression, genome editing to develop rice lines with lower susceptibility to sheath blight and development of transgenic rice lines overexpressing or silencing pathogenesis related genes. The main challenges that were identified for effective crop protection against sheath blight are the adaptive flexibility of the pathogen, lack of resistant rice varieties, abscence of single resistance genes for use in breeding and low access of farmers to awareness programmes for optimal management practices.
  10. Fulltext Serological response to influenza vaccination among children vaccinated for multiple influenza seasons
    Rafiq S, Russell ML, Webby R, Fonseca K, Smieja M, Singh P, et al.
    PLoS One, 2012;7(12):e51498.
    PMID: 23240030 DOI: 10.1371/journal.pone.0051498
    BACKGROUND: To evaluate if, among children aged 3 to 15 years, influenza vaccination for multiple seasons affects the proportion sero-protected.

    METHODOLOGY/PRINCIPAL FINDINGS: Participants were 131 healthy children aged 3-15 years. Participants were vaccinated with trivalent inactivated seasonal influenza vaccine (TIV) over the 2005-06, 2006-07 and 2007-8 seasons. Number of seasons vaccinated were categorized as one (2007-08); two (2007-08 and 2006-07 or 2007-08 and 2005-06) or three (2005-06, 2006-07, and 2007-08). Pre- and post-vaccination sera were collected four weeks apart. Antibody titres were determined by hemagglutination inhibition (HAI) assay using antigens to A/Solomon Islands/03/06 (H1N1), A/Wisconsin/67/05 (H3N2) and B/Malaysia/2506/04. The proportions sero-protected were compared by number of seasons vaccinated using cut-points for seroprotection of 1:40 vs. 1:320. The proportions of children sero-protected against H1N1 and H3N2 was high (>85%) regardless of number of seasons vaccinated and regardless of cut-point for seroprotection. For B Malaysia there was no change in proportions sero-protected by number of seasons vaccinated; however the proportions protected were lower than for H1N1 and H3N2, and there was a lower proportion sero-protected when the higher, compared to lower, cut-point was used for sero-protection.

    CONCLUSION/SIGNIFICANCE: The proportion of children sero-protected is not affected by number of seasons vaccinated.

    Nanoscale Adv, 2023 Feb 14;5(4):992-1010.
    PMID: 36798507 DOI: 10.1039/d2na00236a
    The current COVID-19 pandemic, with its numerous variants including Omicron which is 50-70% more transmissible than the previously dominant Delta variant, demands a fast, robust, cheap, and easily deployed identification strategy to reduce the chain of transmission, for which biosensors have been shown as a feasible solution at the laboratory scale. The use of nanomaterials has significantly enhanced the performance of biosensors, and the addition of CNTs has increased detection capabilities to an unrivaled level. Among the various CNT-based detection systems, CNT-based field-effect transistors possess ultra-sensitivity and low-noise detection capacity, allowing for immediate analyte determination even in the presence of limited analyte concentrations, which would be typical of early infection stages. Recently, CNT field-effect transistor-type biosensors have been successfully used in the fast diagnosis of COVID-19, which has increased research and commercial interest in exploiting current developments of CNT field-effect transistors. Recent progress in the design and deployment of CNT-based biosensors for viral monitoring are covered in this paper, as are the remaining obstacles and prospects. This work also highlights the enormous potential for synergistic effects of CNTs used in combination with other nanomaterials for viral detection.
  12. Prospects and progress in the production of valuable carotenoids: Insights from metabolic engineering, synthetic biology, and computational approaches
    Sankari M, Rao PR, Hemachandran H, Pullela PK, Doss C GP, Tayubi IA, et al.
    J Biotechnol, 2018 Jan 20;266:89-101.

    Carotenoids are isoprenoid pigments synthesized exclusively by plants and microorganisms and play critical roles in light harvesting, photoprotection, attracting pollinators and phytohormone production. In recent years, carotenoids have been used for their health benefits due to their high antioxidant activity and are extensively utilized in food, pharmaceutical, and nutraceutical industries. Regulation of carotenoid biosynthesis occurs throughout the life cycle of plants, with vibrant changes in composition based on developmental needs and responses to external environmental stimuli. With advancements in metabolic engineering techniques, there has been tremendous progress in the production of industrially valuable secondary metabolites such as carotenoids. Application of metabolic engineering and synthetic biology has become essential for the successful and improved production of carotenoids. Synthetic biology is an emerging discipline; metabolic engineering approaches may provide insights into novel ideas for biosynthetic pathways. In this review, we discuss the current knowledge on carotenoid biosynthetic pathways and genetic engineering of carotenoids to improve their nutritional value. In addition, we investigated synthetic biological approaches for the production of carotenoids. Theoretical biology approaches that may aid in understanding the biological sciences are discussed in this review. A combination of theoretical knowledge and experimental strategies may improve the production of industrially relevant secondary metabolites.

    Kumar Singh A, Sulugodu Ramachandra S, Arora S, Dicksit DD, Kalyan CG, Singh P
    J Oral Biol Craniofac Res, 2017 Sep-Dec;7(3):158-160.
    PMID: 29123992 DOI: 10.1016/j.jobcr.2017.08.008
    Introduction: Oral tori and exostosis are non-pathological bony protuberances seen on the alveolar surfaces of the jaw bones. These are commonly seen on the palatal surfaces of the maxilla [torus palatinus (TP)] and around the premolars in the lingual surface of the mandible [torus mandibularis (TM)]. The aim of this cross-sectional study was to determine the prevalence of tori/exostosis in the Malaysian population.

    Methodology: A total of 2666 patients were examined for the presence of tori and exostosis in the maxilla and mandible and were categorized into TP, TM, and exostosis (facial/labial). Collected data was analysed for obtaining descriptive statistics.

    Results: 882 subjects were noticed with oral tori/exostosis among the population studied with a prevalence rate of 33%. TP was seen more in females (35%), compared to males (20%), and this difference was statistically significant (p value p value

    Synthetic plastics, which are lightweight, durable, elastic, mouldable, cheap, and hydrophobic, were originally invented for human convenience. However, their non-biodegradability and continuous accumulation at an alarming rate as well as subsequent conversion into micro/nano plastic scale structures via mechanical and physio-chemical degradation pose significant threats to living beings, organisms, and the environment. Various minuscule forms of plastics detected in water, soil, and air are making their passage into living cells. High temperature and ambient humidity increase the degradation potential of plastic polymers photo-catalytically under sunlight or UV-B radiations. Microplastics (MPs) of polyethylene terephthalate, polyethylene, polystyrene, polypropylene, and polyvinyl chloride have been detected in bottled water. These microplastics are entering into the food chain cycle, causing serious harm to all living organisms. MPs entering into the food chain are usually inert in nature, possessing different sizes and shapes. Once they enter a cell or tissue, it causes mechanical damage, induces inflammation, disturbs metabolism, and even lead to necrosis. Various generation routes, types, impacts, identification, and treatment of microplastics entering the water bodies and getting associated with various pollutants are discussed in this review. It emphasizes potential detection techniques like pyrolysis, gas chromatography-mass spectrometry (GC-MS), micro-Raman spectroscopy, and fourier transform infrared spectroscopy (FT IR) spectroscopy for microplastics from water samples.

    Ahmad H, Umar K, Ali SG, Singh P, Islam SS, Khan HM
    Mikrochim Acta, 2018 05 10;185(6):290.
    PMID: 29748777 DOI: 10.1007/s00604-018-2829-z
    A column sorbent for arsenic was obtained through immobilization of highly branched polyethylenimine (PEI) on graphene oxide (GO). The composite material enables speciation of arsenic by tuning the pH of the sample solution which governs the surface charge of the sorbent, depending on whether amino groups (-NH2) are present (at high pH) or ammonium groups (-NH3+; at low pH). The composite can be applied to improved speciation of arsenic (compared to unmodified GO). There is no need for oxidation or reduction of arsenic. A column procedure was applied for the sequestered extraction and speciation of As(III) and As(V) from environmental water samples before their determination by hydride generation-microwave induced plasma-atomic emission spectrometry. The method has a preconcentration factor of 440 for As(III) and of 400 for As(V). The limits of detection (at 3 S/N) are extremely low, being 1.8 ± 0.2 ngL-1 for As(III) and 1.3 ± 0.08 ngL-1 for As(V). This is much lower than the arsenic guideline value of 10 μgL-1 as given by the WHO. Graphical abstract Graphene oxide interconnected with polyethyleneimine has been employed for the speciation and determination of arsenic. Quantitation by atomic emission spectroscopy reveals a high preconcentration factor (440 and 400) and low LODs of 1.8 ± 0.2 and 1.3 ± 0.08 ngL-1for As(III) and As(V), respectively.
  17. Pharmacologic downregulation of protein arginine methyltransferase1 expression by adenosine dialdehyde increases cell senescence in breast cancer
    Singh P, Charles S, Madhavan T, Munusamy-Ramanujam G, Saraswathi NT, Arasu MV, et al.
    Eur J Pharmacol, 2021 Jan 15;891:173697.
    PMID: 33144068 DOI: 10.1016/j.ejphar.2020.173697
    We investigated the role of protein arginine methylation (PAM) in estrogen receptor (ER)-positive breast cancer cells through pharmacological intervention. Tamoxifen (TAM) or adenosine dialdehyde (ADOX), independently, triggered cell cycle arrest and down-regulated PAM, as reduced protein arginine methyltransferase1 (PRMT1) mRNA and asymmetric dimethylarginine (ADMA) levels. Synergistic effect of these compounds elicited potent anti-cancer effect. However, reduction in ADMA was not proportionate with the compound-induced down-regulation of PRMT1 mRNA. We hypothesized that the disproportionate effect is due to the influence of the compounds on other methyltransferases, which catalyze the arginine dimethylation reaction and the diversity in the degree of drug-protein interaction among these methyltransferases. In silico analyses revealed that independently, ADOX or TAM, binds with phosphatidylethanolamine-methyltransferase (PEMT) or betaine homocysteine-methyl transferase (BHMT); and that the binding affinity of ADOX with PEMT or BHMT is prominent than TAM. These observations suggest that in breast cancer, synergistic effect of ADOX + TAM elicits impressive protective function by regulating PAM; and plausibly, restoration of normal enzyme activities of methyltransferases catalyzing arginine dimethylation could have clinical benefits.

    PMID: 36940023 DOI: 10.1007/s11356-023-26399-2
    The aim of this research was to develop a model for a solar refrigeration system (SRS) that utilizes an External Compound Parabolic Collector and a thermal energy storage system (TESS) for solar water heating in Chennai, India. The system parameters were optimized using TRNSYS software by varying factors such as collector area, mass flow rate of heat transfer fluid, and storage system volume and height. The resulting optimized system was found to meet 80% of hot water requirements for the application on an annual basis, with an annual collector energy efficiency of 58% and an annual TESS exergy efficiency of 64% for a discharge period of 6 h per day. In addition, the thermal performance of 3.5 kW SRS was studied by connecting it to an optimized solar water heating system (SWHS). The system was found to generate an average cooling energy of 12.26 MJ/h annually, with a coefficient of performance of 0.59. By demonstrating the ability to efficiently generate both hot water and cooling energy, the results of this study indicate the potential for utilizing a SWHS in combination with STST and SRS. The optimization of system parameters and the use of exergy analysis provide valuable insights into the thermal behavior and performance of the system, which can inform future designs and improve the overall efficiency of similar systems.
