  1. Natural Polyphenols in the Treatment of Alzheimer's Disease
    Syarifah-Noratiqah SB, Naina-Mohamed I, Zulfarina MS, Qodriyah HMS
    Curr Drug Targets, 2018;19(8):927-937.

    Neurodegenerative disease is an incurable disease which involves the degeneration or death of the nerve cells. Alzheimer's Disease (AD) is a neurodegenerative disease discovered in 1906 by Alois Alzheimer, a German clinical psychiatrist and neuroanatomist. The main pathological hallmarks of this disease are the formation of extracellular amyloid β (Aβ) plaques and intracellular neurofibrillary tangle (NFT). The accumulation of the amyloid protein aggregates in the brain of AD patients leads to oxidative stress and inflammation. Other postulated reasons for the development of this disease are cholinergic depletion and excessive glutamatergic neurotransmission. The current drugs approved and marketed for the treatment of AD are cholinesterase inhibitors (ChEIs) and N-methyl-Daspartate (NMDA) receptor antagonists. The function of ChEIs is to avoid cholinergic depletion; whereas the function of NMDA receptor antagonist is to block excessive glutamatergic neurotransmission. Unfortunately, the current drugs prescribed for AD show only modest improvement in terms of symptomatic relief and delay the progression of the disease. This review will discuss about several polyphenolic compounds as potential natural treatment options for AD. Three compounds are highlighted in this review - Curcumin (Cur), Resveratrol (Rsv) and Epigallocatechin-3- gallate (EGCG). These compounds have huge potential for AD treatment, especially due to their low frequency of adverse events. However, the current conventional pharmaceutical drugs remain as the mainstay of treatment for AD.

    Hepatocellular carcinoma (HCC) is a malignant tumour of the hepatocyte. It is a common malignancy worldwide and causes almost half a million deaths annually. Asia is a high risk area. Although surgery (hepatectomy or liver transplantation) is the main form of curative treatment, the majority of patients are not eligible for surgery due to extent of tumour and dysfunction of liver. Radiopharmaceuticals used for transarterial treatment of HCC were Yttrium-90 microspheres, Iodine-131 lipiodol, Rhenium-188 lipiodol, and Holmium-166 Chitosan complex. Yittrium-90 microspheres are glass or resin microspheres of mean sphere diameter of 20 to 30 micrometre. The activity administered was about 4 GBq. Reported response rate was about 20%, and median survival was 54 weeks. On inoperable tumours, reported objective response of I-131 lipiodol was 40 to 70%, and median survival was six to nine months. It showed efficacy similar to TACE. In adjuvant treatment following curative resection of HCC, reported three year survival was 86% compared with 46% for the control group. The administered activity in both adjuvant and inoperable HCC was about 2 GBq (55 mCi). Rhenium-188 lipiodol is a new radioconjugate, and using it we treated 70 patients with inoperable HCC. This treatment was a part of a multi-centre trial sponsored by the International Atomic Energy Agency. Partial response was obtained in 17% of cases, while 49% had stable disease at three months, and 34% showed disease progression. In terms of survival, 19% survived one year, 60% for six months, and 90% for three months. The mean activity was about 4.6 GBq (124 mCi). This method was safe and free from adverse effects.

    Sundararajan V, Sarkar FH, Ramasamy TS
    Cell Oncol (Dordr), 2018 06;41(3):223-252.
    PMID: 29667069 DOI: 10.1007/s13402-018-0378-4
    BACKGROUND: Recent advances in cancer biology have highlighted the relevance of exosomes and nanovesicles as carriers of genetic and biological messages between cancer cells and their immediate and/or distant environments. It has been found that these molecular cues may play significant roles in cancer progression and metastasis. Cancer cells secrete exosomes containing diverse molecules that can be transferred to recipient cells and/or vice versa to induce a plethora of biological processes, including angiogenesis, metastasis formation, therapeutic resistance, epithelial-mesenchymal transition and epigenetic/stemness (re)programming. While exosomes interact with cells within the tumour microenvironment to promote tumour growth, these vesicles can also facilitate the process of distant metastasis by mediating the formation of pre-metastatic niches. Next to their tumour promoting effects, exosomes have been found to serve as potential tools for cancer diagnosis and therapy. The ease of isolating exosomes and their content from different body fluids has led to the identification of diagnostic and prognostic biomarker signatures, as well as to predictive biomarker signatures for therapeutic responses. Exosomes can also be used as cargos to deliver therapeutic anti-cancer drugs, and they can be engineered to serve as vaccines for immunotherapy. Additionally, it has been found that inhibition of exosome secretion, and thus the transfer of oncogenic molecules, holds promise for inhibiting tumour growth. Here we provide recent information on the diverse roles of exosomes in various cellular and systemic processes governing cancer progression, and discuss novel strategies to halt this progression using exosome-based targeted therapies and methods to inhibit exosome secretion and the transfer of pro-tumorigenic molecules.

    CONCLUSIONS: This review highlights the important role of exosomes in cancer progression and its implications for (non-invasive) diagnostics and the development of novel therapeutic strategies, as well as its current and future applications in clinical trials.

  4. Upregulation of catalase and downregulation of glutathione peroxidase activity in the kidney precede the development of hypertension in pre-hypertensive SHR
    Sundaram A, Siew Keah L, Sirajudeen KN, Singh HJ
    Hypertens Res, 2013 Mar;36(3):213-8.
    PMID: 23096233 DOI: 10.1038/hr.2012.163
    Although oxidative stress has been implicated in the pathogenesis of hypertension in spontaneously hypertensive rats (SHRs), there is little information on the levels of primary antioxidant enzymes status (AOEs) in pre-hypertensive SHR. This study therefore determined the activities of primary AOEs and their mRNA levels, levels of hydrogen peroxide (H2O2), malondialdehyde (MDA) and total antioxidant status (TAS) in whole kidneys of SHR and age-matched Wistar-Kyoto (WKY) rats aged between 2 and 16 weeks. Compared with age-matched WKY rats, catalase (CAT) activity was significantly higher from the age of 2 weeks (P<0.001) and glutathione peroxide (GPx) activity was lower from the age of 3 weeks (P<0.001) in SHR. CAT mRNA levels were significantly higher in SHR aged 2, 4, 6 and 12 weeks. GPx mRNA levels were significantly lower in SHR at 8 and 12 weeks. Superoxide dismutase activity or its mRNA levels were not different between the two strains. H2O2 levels were significantly lower in SHR from the age of 8 weeks (P<0.01). TAS was significantly higher in SHR from the age of 3 weeks (P<0.05). MDA levels were only significantly higher at 16 weeks of age in the SHR (P<0.05). The data suggest that altered renal CAT and GPx mRNA expression and activity precede the development of hypertension in SHR. The raised CAT activity perhaps contributes to the higher TAS and lower H2O2 levels in SHR. In view of these findings, the precise role of oxidative stress in the pathogenesis of hypertension in SHR needs to be investigated further.

  5. Fulltext Low levels of caries in aggressive periodontitis: A literature review
    Sulugodu Ramachandra S
    Saudi Dent J, 2014 Apr;26(2):47-9.
    PMID: 25408595 DOI: 10.1016/j.sdentj.2013.12.002
    This article is a traditional literature review on caries levels in aggressive periodontitis. Aggressive periodontitis generally affects systemically healthy individuals aged <30 years (older individuals can also be affected) and is characterized by a young age of onset, rapid rate of disease progression, and familial aggregation of cases. Dental caries is caused by the dissolution of enamel by acid-producing bacteria present in the plaque biofilm, especially when the biofilm reaches critical mass due to improper oral hygiene. The association between caries level and aggressive periodontitis has long been debated. Initial research indicated that caries levels were high in patients with aggressive periodontitis, but high-quality studies have consistently shown that caries and aggressive periodontitis are inversely related. A recent in vitro study showed that Streptococcus mutans was killed more readily in the saliva of patients with aggressive periodontitis and Aggregatibacter actinomycetemcomitans positivity than in patients with A. actinomycetemcomitans negativity. Other mechanisms possibly explaining the inverse relationship between caries and aggressive periodontitis in cases of Down's syndrome are also discussed in this literature review. The usefulness of caries level in the diagnosis of aggressive periodontitis in developing countries such as India, where the disease is diagnosed primarily on the basis of clinical and radiographic features and familial history is also discussed.

  6. Fulltext Fluoroscopy assisted minimally invasive transplantation of allogenic mesenchymal stromal cells embedded in HyStem reduces the progression of nucleus pulposus degeneration in the damaged ntervertebral [corrected] disc: a preliminary study in rabbits
    Subhan RA, Puvanan K, Murali MR, Raghavendran HR, Shani S, Abdullah BJ, et al.
    ScientificWorldJournal, 2014;2014:818502.
    PMID: 24983002 DOI: 10.1155/2014/818502
    This study was conducted to develop a technique for minimally invasive and accurate delivery of stem cells to augment nucleus pulposus (NP) in damaged intervertebral discs (IVD). IVD damage was created in noncontiguous discs at L4-L5 level; rabbits (N = 12) were randomly divided into three groups: group I treated with MSCs in HyStem hydrogel, group II treated with HyStem alone, and group III received no intervention. MSCs and hydrogel were administered to the damaged disc under guidance of fluoroscopy. Augmentation of NP was assessed through histological and MRI T2 mapping of the NP after eight weeks of transplantation. T2 weighted signal intensity was higher in group I than in groups II and III (P < 0.05). Disc height index showed maximum disc height in group I compared to groups II and III. Histological score of the degenerative index was significantly (P < 0.05) lower in group I (8.6 ± 1.8) than that in groups II (11.6 ± 2.3) and III (18.0 ± 5.7). Immunohistochemistry staining for collagen type II and aggrecan staining were higher in group I as compared to other groups. Our results demonstrate that the minimally invasive administration of MSCs in hyaluronan hydrogel (HyStem) augments the repair of NP in damaged IVD.

  7. Melatonin in Alzheimer's disease and other neurodegenerative disorders
    Srinivasan V, Pandi-Perumal SR, Cardinali DP, Poeggeler B, Hardeland R
    Behav Brain Funct, 2006 May 04;2:15.
    PMID: 16674804
    Increased oxidative stress and mitochondrial dysfunction have been identified as common pathophysiological phenomena associated with neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD) and Huntington's disease (HD). As the age-related decline in the production of melatonin may contribute to increased levels of oxidative stress in the elderly, the role of this neuroprotective agent is attracting increasing attention. Melatonin has multiple actions as a regulator of antioxidant and prooxidant enzymes, radical scavenger and antagonist of mitochondrial radical formation. The ability of melatonin and its kynuramine metabolites to interact directly with the electron transport chain by increasing the electron flow and reducing electron leakage are unique features by which melatonin is able to increase the survival of neurons under enhanced oxidative stress. Moreover, antifibrillogenic actions have been demonstrated in vitro, also in the presence of profibrillogenic apoE4 or apoE3, and in vivo, in a transgenic mouse model. Amyloid-beta toxicity is antagonized by melatonin and one of its kynuramine metabolites. Cytoskeletal disorganization and protein hyperphosphorylation, as induced in several cell-line models, have been attenuated by melatonin, effects comprising stress kinase downregulation and extending to neurotrophin expression. Various experimental models of AD, PD and HD indicate the usefulness of melatonin in antagonizing disease progression and/or mitigating some of the symptoms. Melatonin secretion has been found to be altered in AD and PD. Attempts to compensate for age- and disease-dependent melatonin deficiency have shown that administration of this compound can improve sleep efficiency in AD and PD and, to some extent, cognitive function in AD patients. Exogenous melatonin has also been reported to alleviate behavioral symptoms such as sundowning. Taken together, these findings suggest that melatonin, its analogues and kynuric metabolites may have potential value in prevention and treatment of AD and other neurodegenerative disorders.

  8. Disclosure of HIV status and associated clinical outcomes of children and adolescents living with HIV in Asia
    Sornillo JB, Ditangco R, Lumbiganon P, Vu TA, Le ON, Truong KH, et al.
    AIDS Care, 2023 Dec;35(12):1928-1937.
    PMID: 36794343 DOI: 10.1080/09540121.2023.2176424
    Disclosure of HIV status is an important part of pediatric care. We studied disclosure and clinical outcomes in a multi-country Asian cohort of children and adolescents with HIV. Those 6-19 years of age who initiated combination antiretroviral therapy (cART) between 2008 and 2018, and who had at least one follow-up clinic visit were included. Data up to December 2019 were analyzed. Cox and competing risk regression analyses were used to assess the effect of disclosure on disease progression (WHO clinical stage 3 or 4), loss to follow-up (LTFU; > 12 months), and death. Of 1913 children and adolescents (48% female; median [IQR] age 11.5 [9.2-14.7] years at last clinic visit), 795 (42%) were disclosed to about their HIV status at a median age of 12.9 years (IQR: 11.8-14.1). During follow-up, 207 (11%) experienced disease progression, 75 (3.9%) were LTFU, and 59 (3.1%) died. There were lower hazards of disease progression (adjusted hazard ratio [aHR] 0.43 [0.28-0.66]) and death (aHR 0.36 [0.17-0.79]) for those disclosed to compared with those who were not. Disclosure and its appropriate implementation should be promoted in pediatric HIV clinics in resource-limited settings.

  9. Fulltext Ambiguous presentations of pulmonary epithelioid hemangioendothelioma: Two case reports of a rare pulmonary malignancy
    Soo CI, Ng BH, Tan EL, Abdul Hamid F
    SAGE Open Med Case Rep, 2016;4:2050313X16650323.
    PMID: 27489719 DOI: 10.1177/2050313X16650323
    Pulmonary epithelioid hemangioendothelioma is an uncommon lung malignancy of endothelial origin. Besides demonstrating unpredictable presentation features and prognosis, the paucity of established treatment guidelines remains a challenge in managing these patients. We present two patients. The first patient presented with chronic productive cough over 1-year duration. He was initially diagnosed and showed partial response to treatment for cardiac failure. A persistent right upper zone consolidation on chest radiograph prompted further investigations which revealed the diagnosis of pulmonary epithelioid hemangioendothelioma. The second patient presented with right-sided hemiparesis for 1-month duration. Initial computer tomography scan of the brain showed findings of distant metastatic foci. Subsequent investigations revealed pulmonary epithelioid hemangioendothelioma as the primary lesion. Both patients succumbed without any treatment due to rapid progression of the disease. We believe that pulmonary epithelioid hemangioendothelioma is undoubtedly rarely reported in south-east Asia region. In these two case reports, the patients were diagnosed in west and east Malaysia, respectively, in the same year (2015). Both cases highlight the increasing prevalence of pulmonary epithelioid hemangioendothelioma. We postulate that this could possibly be secondary to the advancement in diagnostic capabilities and improved healthcare facilities available in this region. Late presentation of pulmonary epithelioid hemangioendothelioma generally results in grave prognosis. Further investigations are required to elucidate the nature of progression and therapeutic options for patients with pulmonary epithelioid hemangioendothelioma.

    Eradication of tuberculosis seems to be a long way off especially with the growing of drug resistance tuberculosis and HIV co-infection tuberculosis. The gaps in our knowledge and the limited sensitive and specific biomarkers especially for latent tuberculosis infection make it defensive. The fate of tuberculosis treatment ranged from cured to failure and there are many risk factors involved apart from the immune state and age. Therefore, this review focuses on the understanding of tuberculosis disease progression and the associated risk factors of the events in the disease progression. This article also highlights the diagnostic and predictive marker that may predict the disease progression. In addition, this review highlights the potential use of rifabutin in tuberculosis treatment regimen. It is hoped that this review could give an overview on future directions of research in tuberculosis.

    Singh VA, Lim CY, Yan HC, Rahman NA
    J Foot Ankle Surg, 2017 06 26;56(6):1292-1297.
    PMID: 28659241 DOI: 10.1053/j.jfas.2017.05.005
    Melanoma is a well-known malignant neoplasm of the skin, although it can also arise from other structures. Bone metastasis is not an uncommon event associated with melanoma, although primary osseous melanoma is very rare. In the present report, we describe a case of primary melanoma arising from the left third metatarsal in an adult male. The lesion was treated with surgical excision without adjunct chemotherapy, and recurrence developed approximately 12 months after the foot surgery. The patient died of the cancer 34 months after it had been identified. Primary melanoma arising in a metatarsal is rare, and we wished to highlight this unusual presentation.

  12. Increased psychosocial risk, depression and reduced quality of life living with autosomal dominant polycystic kidney disease
    Simms RJ, Thong KM, Dworschak GC, Ong AC
    Nephrol Dial Transplant, 2016 07;31(7):1130-40.
    PMID: 26268712 DOI: 10.1093/ndt/gfv299
    BACKGROUND: The psychosocial impact of living with autosomal dominant polycystic kidney disease (ADPKD) is poorly understood. In this study, we assessed the overall quality of life (QOL), mood, perceived social support and psychosocial risk of having a diagnosis of ADPKD in a patient cohort from a major UK nephrology centre serving a large catchment population.

    METHODS: A postal questionnaire was sent to 349 patients registered at the Sheffield Kidney Institute with chronic kidney disease but not on renal replacement therapy (RRT). The questionnaire incorporated three validated forms: kidney disease quality-of-life short form (KDQOL SF1.3) to assess QOL; nine-item patient health questionnaire (PHQ9) to screen for depression; multidimensional scale of perceived social support (MSPSS) to evaluate perceived social support; as well as a novel genetic psychosocial risk instrument (GPRI-ADPKD) designed to study the specific psychosocial impact of coping with a diagnosis of ADPKD.

    RESULTS: The overall response rate was 53%. Patients with a lower estimated glomerular filtration rate (<30 mL/min) or larger kidneys (mean length on ultrasound ≥17 cm) reported reduced QOL and increased psychosocial risk. Clinically significant depression was reported in 22% and 62% felt guilty about passing ADPKD on to their children. In multivariate analysis, female gender was associated with overall poorer psychosocial well-being, whereas increasing age, lower kidney function, larger kidneys and loss of a first degree relative from ADPKD were additional risk factors for QOL, depression or psychosocial risk, respectively.

    CONCLUSIONS: Our results reveal a significantly poorer QOL and increasing psychosocial risk with markers of disease progression in patients, particularly women, with ADPKD prior to starting RRT. The future management strategy of ADPKD should address these issues and provide for better individual and family support throughout the patient journey.

    Introduction: Although the benefit of low protein diet (LPD) on chronic kidney disease (CKD) progression is well documented, patients’ adherence remains as the main challenge. Therefore, this study sought to identify adherence towards LPD among CKD patients and determine possible associating factors. Methods: This cross-sectional study was done at the Hospital Pakar Sultanah Fatimah in Muar, Johor, among stage III to V CKD patients. Three-day dietary recalls were used to quantify dietary energy (DEI) and protein intake (DPI). Factors investigated include socio-demo- graphic characteristics, medical history, anthropometry and body composition measurements, dietary knowledge, appetite level, handgrip strength, perceived stress, and health locus of control. Associating variables were analysed with logistic regression analysis. Results: The final analysis included 113 patients (54% male) with a mean estimated glomerular filtration rate of 17.5±11.2mL/min/1.73m2 and the average age of 56.3±12.8 years. Mean DEI and DPI were 22.4±5.9kcal/kg/day and 0.83±0.28g/kg/day, respectively. Only 34.5% of patients adhere to the LPD diet with 59% exceeding the DPI recommendation. Poorer LPD adherence was associated with longer duration of hospitaliza- tion (OR 0.707, 95%CI 0.50-1.00, p=0.048), higher energy intake (OR 0.744, 95%CI 0.65-0.85, p

  16. Fulltext Upregulation of miR-101 during Influenza A Virus Infection Abrogates Viral Life Cycle by Targeting mTOR Pathway
    Sharma S, Chatterjee A, Kumar P, Lal S, Kondabagil K
    Viruses, 2020 04 15;12(4).
    PMID: 32326380 DOI: 10.3390/v12040444
    Micro RNAs (miRNAs) are a class of small non-coding single-stranded RNA, which play an important role in modulating host-Influenza A virus (IAV) crosstalk. The interplay between influenza and miRNA interaction is defined by a plethora of complex mechanisms, which are not fully understood yet. Here, we demonstrate that in IAV infected A549 cells, a synchronous increase was observed in the expression of mTOR up to 24 hpi and significant downregulation at 48 hpi. Additionally, NP of IAV interacts with mTOR and modulates the levels of mTOR mRNA and protein, thus regulating the translation of host cell. RNA sequencing and qPCR analysis of IAV-infected A549 cells and NP transfected cells revealed that miR-101 downregulates mTOR transcripts at later stages of infection. Ectopic expression of miR-101 mimic led to a decrease in expression of NP, a reduction in IAV titer and replication. Moreover, treatment of the cells with Everolimus, a potent inhibitor of mTOR, resulted in an increase of miR-101 transcript levels, which further suppressed the viral protein synthesis. Collectively, the data suggest a novel mechanism that IAV stimulates mTOR pathway at early stages of infection; however, at a later time-point, positive regulation of miR-101 restrains the mTOR expression, and hence, the viral propagation.

    Immunosenescence is marked by accelerated degradation of host immune responses leading to the onset of opportunistic infections, where senescent T cells show remarkably higher ontogenic defects as compared to healthy T cells. The mechanistic association between T-cell immunosenescence and human immunodeficiency virus (HIV) disease progression, and functional T-cell responses in HIV-tuberculosis (HIV-TB) co-infection remains to be elaborately discussed. Here, we discussed the association of immunosenescence and chronic immune activation in HIV-TB co-infection and reviewed the role played by mediators of immune deterioration in HIV-TB co-infection necessitating the importance of designing therapeutic strategies against HIV disease progression and pathogenesis.

    While the past 2 decades have witnessed an increasing understanding of amyotrophic lateral sclerosis (ALS) arising from East Asia, particularly Japan, South Korea, Taiwan and China, knowledge of ALS throughout the whole of Asia remains limited. Asia represents >50% of the world population, making it host to the largest patient cohort of ALS. Furthermore, Asia represents a diverse population in terms of ethnic, social and cultural backgrounds. In this review, an overview is presented that covers what is currently known of ALS in Asia from basic epidemiology and genetic influences, through to disease characteristics including atypical phenotypes which manifest a predilection for Asians. With the recent establishment of the Pan-Asian Consortium for Treatment and Research in ALS to facilitate collaborations between clinicians and researchers across the region, it is anticipated that Asia and the Pacific will contribute to unravelling the uncertainties in ALS.

  19. Systemic lupus erythematosus among male patients in Malaysia: how are we different from other geographical regions?
    Shaharir SS, Kadir WDA, Nordin F, Bakar FA, Ting MWH, Jamil A, et al.
    Lupus, 2019 Jan;28(1):137-144.
    PMID: 30458692 DOI: 10.1177/0961203318812676
    BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease which predominantly affects females. The disease characteristics in male SLE patients are reported to be distinct and may vary across ethnicities and geographical regions.

    OBJECTIVE: To determine and compare the clinical phenotype and organ damage between male and female patients with SLE in Malaysia.

    METHODOLOGY: This was a cross-sectional study involving SLE patients from Universiti Kebangsaan Malaysia Medical Centre from June 2016 until June 2017. Information on their socio-demographics and disease characteristics were obtained from the clinical records. Disease damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index (SDI) scores. The disease characteristics, autoantibody profiles and organ damage were compared between male and female patients, and multivariable analysis using male sex as dependent variable was then performed.

    RESULTS: A total of 418 patients were recruited and a total of 59 (14.1%) patients were male. Male patients presented with lower SLE ACR criteria at initial presentation but a significantly higher number of them had renal involvement (lupus nephritis) (78.0% versus 63.8%, p = 0.04). Male patients had less musculoskeletal involvement (45.8% versus 63.0%, p = 0.02) and tended to have lesser mucocutaneous involvement. Immunologic profile revealed that a lower number of male patients had positive anti-Ro antibody (22.7% versus 44.7%, p = 0.04) and they tended to have positive lupus anticoagulant antibody (27.6% versus 14.3%, p = 0.06). Presence of organ damage (SDI score ≥ 1) was significantly higher among males (55.9% versus 39.6%, p = 0.02) with higher renal damage (25.4% versus 9.2%, p = 0.004) and cardiovascular event of ischaemic heart disease or stroke (20.3% versus 7.0%, p = 0.004). They were also inclined to develop damage much earlier as compared to female patients, 3 (interquartile range (IQR) 7.5) versus 5 (IQR 7) years, p = 0.08. The occurrence of disease damage was independently associated with male gender with odds ratio of 1.9 (95% confidence interval 1.1-3.5), p = 0.02.

    CONCLUSION: Male patients with SLE have more severe disease with renal damage and cardiovascular event.
