Fulltext Nanopore sequencing-based genotyping suggested an association between CYP2D6 function and susceptibility to anxiety and depression

Chua EW, Karunanathie H, Yanasegaran K, Maggo S, Kee PS, Kennedy M, et al.

BMC Res Notes, 2025 Feb 27;18(1):88.

PMID: 40016731 DOI: 10.1186/s13104-025-07156-9

OBJECTIVE: CYP2D6 activity has been inconsistently associated with anxious and depressive personality traits. The inconsistency may stem from limitations of targeted genotyping, employed in most previous studies, leading to undetected errors in metabolic classification. Using a nanopore sequencing-based method, we comprehensively genotyped CYP2D6 alleles in a small cohort of 96 Malaysians and re-examined the relationship between CYP2D6 activity and susceptibility to anxiety and depression.

RESULTS: In keeping with prior studies, CYP2D6*10 was found to be the most common defective allele. Nearly half of the (48.5%) participants were classified as intermediate and poor metabolizers. Linear regression analysis suggested that impaired CYP2D6 activity could be a predictor of anxiety and depression, consistent with the putative role of CYP2D6 in the synthesis of serotonin and dopamine, the mood-boosting neurotransmitters. We hope this brief report will prompt larger-scale studies to further elucidate the contribution of CYP2D6 to the genetic underpinnings of mental well-being.

Nucleotide sequence and phylogenetic analysis of Newcastle disease virus isolates from recent outbreaks in Taiwan

Yang CY, Chang PC, Hwang JM, Shieh HK

Avian Dis, 1997 Apr-Jun;41(2):365-73.

PMID: 9201401

Portions of the hemagglutinin neuraminidase (HN) gene of Newcastle disease virus (NDV) isolates from two recent outbreaks were sequenced to investigate epidemiology of this disease in Taiwan. These NDV isolates were all viscerotropic velogenic according to the clinical lesions produced in chickens. Sequence data were obtained from 14 NDV isolates (12 from 1995 and 2 from 1984). All isolates differed in their nucleotide sequences (from 0.3 to 15.3%), and represented potentially different strains of NDV. Phylogenetic analysis revealed that these isolates are closely related to viruses isolated from Japan and Malaysia. Some viruses isolated in 1995 appeared to evolve from viruses isolated in 1984. The results suggest that the 1995 outbreak of Newcastle disease (ND) in Taiwan may have been caused by multiple strains of velogenic NDV that have cocirculated in Taiwan for some time. Moreover, NDV isolates from racing pigeons were very similar to isolates from chickens in the same period, suggesting that both domestic and free-living birds were involved in the spread of ND in Taiwan.

Value Health, 2014 Nov;17(7):A594.

PMID: 27202038 DOI: 10.1016/j.jval.2014.08.2045

Objectives: The cost of acute exacerbations of asthma had not been well studied in literature. The aim of this study was to identify and quantify the (average) cost of moderate and severe exacerbations of asthma in patients attending tertiary-care setup in Malaysia. The related burden of exacerbations was also calculated.
Methods: The costs including lab investigation charges, unit costs of treatment per bed, medication charges, food costs, transportation costs and loss of productivity were calculated per asthma episode. Data was analysed by Statistical Package for the Social Sciences (SPSS) version 18.0 using various descriptive and inferential statistical tests.
Results: A median medical cost of acute exacerbation of asthma under Ministry of Health’s (MOH) perspective was USD 105.00 (RM338.47) per episode. Medication cost comprised the majority (52.38%) of the total medical costs. A median medical cost of acute exacerbation of asthma under patient’s perspective was USD 1.55 (RM4.99) per episode. ConclusionsAsthma exacerbation and length of stay in the hospital were proportional to the direct medical costs. In Malaysia, a substantial proportion of the direct medical cost of asthma treatment is heavily subsidised for the locals.

PMID: 25167786 DOI: 10.1111/jgh.12714

BACKGROUND AND AIM: Although studies have suggested that rs780094, a common variant in the glucokinase regulatory (GCKR) gene to be associated with type 2 diabetes, obesity, and their related traits, the genetic basis of the association between GCKR rs780094 and nonalcoholic fatty liver disease (NAFLD) is still being examined. This meta-analysis was performed to evaluate the effect strength caused by GCKR rs780094 on NAFLD.
METHODS: We searched Medline, PubMed, Scopus, and Embase for relevant articles published up to April 2014. Data were extracted, and summary estimates of the association between GCKR rs780094 and NAFLD were examined. Heterogeneity and publication bias were also examined.
RESULTS: This meta-analysis incorporated a total of 2091 NAFLD cases and 3003 controls from five studies. Overall, the pooled result indicated that the GCKR rs780094 was significantly associated with increased risk of NAFLD (additive: odds ratio (OR) 1.25, 95% confidence interval (CI) 1.14-1.36, P

Optimal set of EEG features for emotional state classification and trajectory visualization in Parkinson's disease

Yuvaraj R, Murugappan M, Ibrahim NM, Sundaraj K, Omar MI, Mohamad K, et al.

Int J Psychophysiol, 2014 Dec;94(3):482-95.

PMID: 25109433 DOI: 10.1016/j.ijpsycho.2014.07.014

In addition to classic motor signs and symptoms, individuals with Parkinson's disease (PD) are characterized by emotional deficits. Ongoing brain activity can be recorded by electroencephalograph (EEG) to discover the links between emotional states and brain activity. This study utilized machine-learning algorithms to categorize emotional states in PD patients compared with healthy controls (HC) using EEG. Twenty non-demented PD patients and 20 healthy age-, gender-, and education level-matched controls viewed happiness, sadness, fear, anger, surprise, and disgust emotional stimuli while fourteen-channel EEG was being recorded. Multimodal stimulus (combination of audio and visual) was used to evoke the emotions. To classify the EEG-based emotional states and visualize the changes of emotional states over time, this paper compares four kinds of EEG features for emotional state classification and proposes an approach to track the trajectory of emotion changes with manifold learning. From the experimental results using our EEG data set, we found that (a) bispectrum feature is superior to other three kinds of features, namely power spectrum, wavelet packet and nonlinear dynamical analysis; (b) higher frequency bands (alpha, beta and gamma) play a more important role in emotion activities than lower frequency bands (delta and theta) in both groups and; (c) the trajectory of emotion changes can be visualized by reducing subject-independent features with manifold learning. This provides a promising way of implementing visualization of patient's emotional state in real time and leads to a practical system for noninvasive assessment of the emotional impairments associated with neurological disorders.

Fulltext LRRK2 G2385R and R1628P mutations are associated with an increased risk of Parkinson's disease in the Malaysian population

Gopalai AA, Lim SY, Chua JY, Tey S, Lim TT, Mohamed Ibrahim N, et al.

Biomed Res Int, 2014;2014:867321.

PMID: 25243190 DOI: 10.1155/2014/867321

The LRRK2 gene has been associated with both familial and sporadic forms of Parkinson's disease (PD). The G2019S variant is commonly found in North African Arab and Caucasian PD patients, but this locus is monomorphic in Asians. The G2385R and R1628P variants are associated with a higher risk of developing PD in certain Asian populations but have not been studied in the Malaysian population. Therefore, we screened the G2385R and R1628P variants in 1,202 Malaysian subjects consisting of 695 cases and 507 controls. The G2385R and R1628P variants were associated with a 2.2-fold (P = 0.019) and 1.2-fold (P = 0.054) increased risk of PD, respectively. Our data concur with other reported findings in Chinese, Taiwanese, Singaporean, and Korean studies.

PMID: 22149618 DOI: 10.1586/eri.11.155

Natural disasters may lead to infectious disease outbreaks when they result in substantial population displacement and exacerbate synergic risk factors (change in the environment, in human conditions and in the vulnerability to existing pathogens) for disease transmission. We reviewed risk factors and potential infectious diseases resulting from prolonged secondary effects of major natural disasters that occurred from 2000 to 2011. Natural disasters including floods, tsunamis, earthquakes, tropical cyclones (e.g., hurricanes and typhoons) and tornadoes have been secondarily described with the following infectious diseases including diarrheal diseases, acute respiratory infections, malaria, leptospirosis, measles, dengue fever, viral hepatitis, typhoid fever, meningitis, as well as tetanus and cutaneous mucormycosis. Risk assessment is essential in post-disaster situations and the rapid implementation of control measures through re-establishment and improvement of primary healthcare delivery should be given high priority, especially in the absence of pre-disaster surveillance data.

By using a pair of tweezers to generate the intense optical vortices within the PANDA ring resonator, the required molecules (drug volumes) can be trapped and moved dynamically within the molecular bus networks, in which the required diagnosis or drug delivery targets can be performed within the network. The advantage of the proposed system is that the proposed diagnostic method can perform within the tiny system (thin film device or circuit), which can be available for a human embedded device for diagnostic use. The channel spacing of the trapped volumes (molecules) within the bus molecular networks can be provided.

PMID: 20527283 MyJurnal

Acute exacerbations of chronic obstructive pulmonary disease (COPD) are important events in COPD patients and place a large burden on healthcare resources. COPD patients with frequent exacerbations have accelerated decline in lung function, poorer health status and are at higher risk of mortality. The mainstay of treatment includes increasing short acting bronchodilator therapy and systemic glucocorticosteroids with or without antibiotics. Non invasive ventilation is indicated in those with respiratory failure with acidosis or hypercapnia. Preventive strategies to reduce exacerbations include smoking cessation, immunisation against influenza and S. pneumonia, chronic maintenance inhaled pharmacotherapy, pulmonary rehabilitation and self management education.

The clinical significance of immunoglobulin A deficiency

Latiff AH, Kerr MA

Ann. Clin. Biochem., 2007 Mar;44(Pt 2):131-9.

PMID: 17362578 DOI: 10.1258/000456307780117993

IgA deficiency is the most common primary immunoglobulin deficiency. The prevalence in Caucasians is around one in 500, whereas in some Asian populations it is very uncommon. Most individuals with IgA deficiency are clinically asymptomatic. Those with symptoms of immunodeficiency have predominantly sinopulmonary or gastrointestinal infections, which are more severe when associated with IgG2, IgG4 or specific antibody deficiency. IgA deficiency is believed to be one end of a spectrum of immunodeficiency with common variable immunodeficiency at the most severe end. Although primary IgA deficiency is the most commonly encountered form, secondary deficiencies due to drugs or viral infections are recognized. IgA deficiencies can be partial or transient. Primary IgA deficiency is caused by a defect of terminal lymphocyte differentiation, which leads to underproduction of serum and mucosal IgA; affected individuals have normal IgA genes. A number of non-immunoglobulin genes have been implicated in IgA deficiency. There have been many diseases reported in association with IgA deficiency, particularly autoimmune diseases. The most common association is with coeliac disease (CD), which has special significance since CD is usually diagnosed by detection of specific IgA antibodies that are obviously lacking in IgA deficiency. There is no specific treatment for patients with symptomatic IgA deficiency. Antibiotics are prescribed in those with acute infections. A significant proportion of IgA-deficient individuals are reported to have anti-IgA antibodies in their serum. Although blood or blood products given to IgA-deficient individuals can lead to severe, even fatal, transfusion reactions, such reactions are rare.

Molecular characterization of recent infectious bursal disease virus isolates from Malaysia

Nurulfiza I, Hair-Bejo M, Omar AR, Aini I

Acta Virol., 2006;50(1):45-51.

PMID: 16599185

Three isolates of Infectious bursal disease virus (IBDV), designated UPM04178, UPM04190 and UPM04238, were obtained from severe outbreaks of infectious bursal disease (IBD) in Malaysia in 2004. The hypervariable region (HPVR) of VP2 gene of these isolates was sequenced. The obtained sequences were compared with those of other isolates. The highest similarity (98%) concerning both nucleotide and amino acid sequences was found to very virulent IBDV (vvIBDV) strains. Phylogenetic analysis revealed clustering of the three isolates with vvIBDV strains. Evolutionary relatedness of the three isolates to vvIBDV strains was demonstrated by three phylogenetic methods: bootstrap values of 100%, 95% and 90% for nucleotide sequences and those of 58%, 86% and 96% for amino acid sequences were obtained by the distance, maximum parsimony and maximum likehood methods, respectively. It is concluded that UPM04178, UPM04190 and UPM04238 are vvIBDV isolates of serotype 1, which originate from a common ancestor of IBDV strains present in Malaysia.
