    Depression is characterized by symptoms like disturbance in behavior, cognition and mood. This is commonly known to affect people aged 60 years and above especially those who are also afflicted with illnesses. The objectives of this study were to determine the prevalence of depression and its associated factors among the elderly in a tertiary care centre in Wilayah Persekutuan. A cross sectional study design was done. Stratified cluster sampling method was used to select the respondents. All elderly patients were selected from the orthopaedic, surgical, gynaecology and medical wards in a government hospital in Wilayah Persekutuan. A 30-item Geriatric Depression Scale questionnaire was used as a screening instrument. Out of the 246 elderly subjects, 198 were interviewed giving a response rate of 80.5%. The results showed that 54% of the elderly respondents were found to have depressive symptoms. Age (p=0.022), sex (p=0.008), ethnicity (p=0.022) and functional disabilities in bathing (p=0.001), grooming (p=0.007), dressing (p= 0.007), using the toilet (p=0.002), transferring from bed to chair and back (p=0.000), mobility (p=0.000) and climbing stairs (p=0.000) were all found to be significantly associated with depression among the elderly respondents. The outcome of this study will have an important impact on the implementation of the health policy for the elderly patients admitted to hospitals.

    Hybrid reinforcement's novel composite (Al-Fe3O4-SiC) via powder metallurgy method was successfully fabricated. In this study, the aim was to define the influence of SiC-Fe3O4 nanoparticles on microstructure, mechanical, tribology, and corrosion properties of the composite. Various researchers confirmed that aluminum matrix composite (AMC) is an excellent multifunctional lightweight material with remarkable properties. However, to improve the wear resistance in high-performance tribological application, hardening and developing corrosion resistance was needed; thus, an optimized hybrid reinforcement of particulates (SiC-Fe3O4) into an aluminum matrix was explored. Based on obtained results, the density and hardness were 2.69 g/cm3, 91 HV for Al-30Fe3O4-20SiC, after the sintering process. Coefficient of friction (COF) was decreased after adding Fe3O4 and SiC hybrid composite in tribology behaviors, and the lowest COF was 0.412 for Al-30Fe3O4-20SiC. The corrosion protection efficiency increased from 88.07%, 90.91%, and 99.83% for Al-30Fe3O4, Al-15Fe3O4-30SiC, and Al-30Fe3O4-20SiC samples, respectively. Hence, the addition of this reinforcement (Al-Fe3O4-SiC) to the composite shows a positive outcome toward corrosion resistance (lower corrosion rate), in order to increase the durability and life span of material during operation. The accomplished results indicated that, by increasing the weight percentage of SiC-Fe3O4, it had improved the mechanical properties, tribology, and corrosion resistance in aluminum matrix. After comparing all samples, we then selected Al-30Fe3O4-20SiC as an optimized composite.

    Rabies is a fatal zoonotic disease caused by rabies virus (RABV) and remains a public health problem in Malaysia. Malaysia was declared rabies-free in 2012, however rabies outbreaks occurred at few states in Peninsular Malaysia three years later; and for the first time, in Sarawak (East Malaysia) in 2017 which has caused more than 20 human deaths. This study describes the phylogenetic analysis of the complete nucleoprotein (N) gene of RABV from animal samples in Malaysia from year 2015 to 2018. The N gene of 17 RABVs from Perlis, Kedah and Sarawak were amplified and sequenced. The nucleotide and deduced amino acid similarities of N gene analysis indicated that there is high similarity among the local RABVs. Phylogenetic analysis of the N gene revealed that all Malaysia RABVs belonged to the Asian clade. Among these, RABVs from Peninsular Malaysia were clustered together with RABVs from Thailand, Vietnam and other Southeast Asia countries except Indonesia. However, RABVs from Sarawak were grouped together with Indonesian strains from Kalimantan. Our study provides baseline genetic information of the potential origins of the circulating RABVs in Malaysia. This crucial information helped the authority in policies making and strategies to be taken in outbreak control. Continuous surveillance program to monitor the disease trend, strict border control, vaccination of dog and cat population and public awareness are important steps to control the spread of the RABV.

    Gestational hypertension (GH) remains one of the main causes of high maternal and perinatal morbidity and mortality worldwide with the highest incidence among primigravidae of about 10%-15%. However, it was noted that the incidence of GH in primigravidae who conceived following assisted reproductive technique (ART) or intrauterine insemination (IUI) supplemented with dydrogesterone during the first trimester was low.

    Polymorphisms within the beta2-adrenergic receptor (ADRB2) gene have been repeatedly linked to hypertension. Among the ADRB2 polymorphisms detected, Arg16Gly and Gln27Glu codons are considered the two most important variations. The amino acid substitution at these codons may lead to abnormal regulation of ADRB2 activity. The aim of the present study was to assess the association between ADRB2 polymorphisms and hypertension. This case-control study consisted of 100 unrelated subjects (50 hypertensive and 50 matched normal controls). Arg16Gly and the Gln27Glu polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism assay. There were no significant evidence of association in allelic and genotypes distribution of Arg16Gly and Glu27Gln with blood pressure and hypertension. These findings suggest that the variation within codon 16 and 27 of ADRB2 gene were unlikely to confer genetic susceptibility for hypertension in our population samples.

    OBJECTIVE: The purposes of this study were to investigate the documentation of the DSM-IV-TR- Criteria A in diagnoses of schizophrenia and to identify the symptoms associated with over diagnosis of schizophrenia.

    METHOD: This study involved a retrospective review and analysis of data from case notes.

    RESULTS: Data of 107 newly diagnosed patients with schizophrenia were keyed in and analyzed using SPSS v 19. The cases were then evaluated for the use of the DSM-IV-TR- Criteria A. Over diagnosis was noted in 37.39% of the patients. Disorganised behaviour (12.5%), affective flattening (12.5%), hallucination (16%) and non-bizarre delusion (18.3%) significantly contributed to the over-diagnosis of schizophrenia. Symptoms such as non-bizarre delusion and hallucination were the most commonly used in over-diagnosing schizophrenia and were statistically significant with p ≤0.05.

    CONCLUSIONS: There was a significant lack of DSM-IV-TR Criteria A among the data documented to diagnose schizophrenia and non-bizarre delusion and hallucination were the most commonly used in over-diagnosing schizophrenia. This key problem needs to be addressed. The reliability of a diagnosis is indispensable and achievable with the proper clinical application of DSM-IV-TR Criteria A. The DSM-IV-TR Criteria have been perceived to be useful and reliable and is most widely used throughout the world.

    Natural fiber reinforced composites have had a great impact on the development of eco-friendly industrial products for several engineering applications. Sugar palm fiber (SPF) is one of the newly found natural fibers with limited experimental investigation. In the present work, sugar palm fiber was employed as the natural fiber reinforcement. The composites were hot compressed with polyvinyl butyral (PVB) to form the structure of laminated composites and then were subjected to tensile testing and moisture absorption. The maximum modulus and tensile strength of 0.84 MPa and 1.59 MPa were registered for samples PVB 80-S and PVB 70-S, respectively. Subsequently, the latter exhibited the highest tensile strain at a maximum load of 356.91%. The moisture absorption test revealed that the samples exhibited better water resistance as the proportion of PVB increased relative to the proportion of SPF due to the remarkable hydrophobic property of PVB in comparison with that of SPF.

    Newcastle disease (ND) is an extremely contagious and fatal viral disease causing huge economic losses to the poultry industry. Following recent ND outbreaks in Sabah in commercial poultry and backyard farms, it was speculated that this could be due to a new introduction of Newcastle Disease Virus (NDV) genotype/sub-genotype. Here we report the genetic characterization of NDVs isolated from Sabah during early 2021. All isolates were amplified and sequenced with primers specific to the viral fusion (F) gene using reverse transcription-polymerase chain reaction (RT-PCR). Nucleotide sequence analysis of the F gene showed that all isolates shared similar homology of 99.4% with NDV strain from Iran isolated in 2018. Amino acid sequences of the F protein cleavage site revealed the motif of 112RRQKRF117 indicating all isolates were of virulent strain. Phylogenetic analysis demonstrated that all isolates were clustered under sub-genotype VII 1.1 and clustered together with isolates from Iran (previously known as subgenotype VIIl). The present findings suggested that there is an emerging of a new sub-genotype into the poultry population in Sabah and this sub-genotype has never been reported before in Malaysia. Therefore, transboundary monitoring and continuous surveillance should be implemented for proper control and prevention of the disease. A further molecular epidemiological analysis of NDV is needed to well understand the circulatory patterns of virulent strains of NDV in the country to prevent future outbreaks.

    This article discusses the design and preparation of a modified MXene-based nanocomposite for increasing the power conversion efficiency and long-term stability of perovskite solar cells. The MXene family of materials among 2D nanomaterials has shown considerable promise in enhancing solar cell performance because of their remarkable surface-enhanced characteristics. Firstly, there are a variety of approaches to making MXene-reinforced composites, from solution mixing to powder metallurgy. In addition, their outstanding features, including high electrical conductivity, Young's modulus, and distinctive shape, make them very advantageous for composite synthesis. In contrast, its excellent chemical stability, electronic conductivity, tunable band gaps, and ion intercalation make it a promising contender for various applications. Photovoltaic devices, which turn sunlight into electricity, are an exciting new area of research for sustainable power. Based on an analysis of recent articles, the hydro-thermal method has been widely used for synthesizing MXene-based nano-composites because of the easiness of fabrication and low cost. Finally, we identify new perspectives for adjusting the performance of MXene for various nanocomposites by controlling the composition of the two-dimensional transition metal MXene phase.

    This article discusses the application of two-dimensional metal MXenes in solar cells (SCs), which has attracted a lot of interest due to their outstanding transparency, metallic electrical conductivity, and mechanical characteristics. In addition, some application examples of MXenes as an electrode, additive, and electron/hole transport layer in perovskite solar cells are described individually, with essential research issues highlighted. Firstly, it is imperative to comprehend the conversion efficiency of solar cells and the difficulties of effectively incorporating metal MXenes into the building blocks of solar cells to improve stability and operational performance. Based on the analysis of new articles, several ideas have been generated to advance the exploration of the potential of MXene in SCs. In addition, research into other relevant MXene suitable in perovskite solar cells (PSCs) is required to enhance the relevant work. Therefore, we identify new perspectives to achieve solar cell power conversion efficiency with an excellent quality-cost ratio.

    INTRODUCTION: Mothers have the ability to provide adequate nutrition for their children. The role of providing nutrition to children aged 6-24 months who are stunted correlated to the mother's ability to provide proper nutrition. The role of mother can be carried out using the ability, confidence, and self-capacity to complete tasks, managing and providing nutrition to children aged 6-24 months who are stunted. This study aimed to analyze complementary feeding based on local food to improve the mothers' ability to fulfill their needs in stunted children.

    MATERIALS AND METHODS: A pre-experiment design was used to obtain data regarding 180 mothers who participated in this study. The complementary feeding based on local- food was conducted for 9 weeks, comprising 2 weeks preintervention, 6 weeks of intervention, and one-week postintervention. The intervention consists of 12 sets of recipes to be made by mothers and given to their children 4 times daily over 6 weeksinstrument using Infant and Young Children Feeding Practice and Structure questionnaire. Data analysis in this study used Wilcoxon Signed Rank Test.

    RESULTS: The result of this study showed that complementary feeding based on local- food could give the impact mothers ability in food preparation and processing before complementary feeding (Z=11.644 and pvalue= 0.000), supplemental feeding (Z=-11.641 and p-value 0.000), and responsive feeding (Z-11.640 and p-value 0.000). The role of feeding responsiveness in accelerated growth. These results prove that self-feeding and maternal verbal responsiveness can be increased by targeting specific behaviours with appropriate behaviour change modeling and coaching practice strategies.

    CONCLUSION: These results provide evidence that focusing on specific behaviours and implementing modification techniques such as modeling and coached practice, complementary feeding based on local food, self-feeding, and maternal verbal responsiveness can be improved.

    African swine fever (ASF) is a transboundary haemorrhagic viral disease that affected domestic and wild pigs of all ages. The disease is caused by African swine fever virus (ASFV) and was introduced to China in 2018 before spreading rapidly to neighbouring Asian countries. As such, putting countries free from ASF like Malaysia at risk. ASF is highly lethal with no vaccine or treatment available. In February 2021, we confirmed backyard pigs from various locations in Sabah were infected with ASF using real time polymerase chain reaction (real- time PCR). Further characterization of the Sabah ASFVs indicated that they were of p72 genotype II with intergenic region (IGR) variant II that displayed an addition tandem repeat sequence (TRS) insertion, similar to ASFV from Indonesia, V ietnam and China. These results indicate and support the transboundary expansion of a homogenotypic ASFV (p72 genotype II and IGR variant II) in the Europe and Asia-Pacific, emphasizing the need for a holistic international collaboration in control and preventing further spreading of the current ASF pandemic. Importantly, our results informed the first detection and characterization of ASF, a disease previously not detected in Malaysia. This information is crucial for further mitigation and preventive measures.

    PMID: 25500844 MyJurnal
    INTRODUCTION: Carotid intima media thickness (CIMT) being a cost effective and easily performed technique is useful in the detection of subclinical atherosclerosis and has been shown to be a prognosticator of cardiovascular events. The primary objective of this study was to obtain the distribution of CIMT measurements, highly sensitive C reactive protein (hs-CRP) and assessing health awareness and attitudes of the Malaysian population at cardiovascular disease (CVD) risk and not receiving lipid lowering agents. Secondarily the study sought to assess the significance of the relationship between these measurements against various patient characteristics.

    METHODS: Measurements of CIMT are obtained by ultrasonography of 12 sites within the common carotid artery was recorded for 123 subjects from a single centre tertiary hospital of Malaysia who had two or more CVD risk factors but were not receiving lipid lowering therapy. CVD risk factors and lipid and glucose profiles were analyzed with respect to distribution of CIMT and high-sensitivity Creactive protein (hs-CRP) values.

    RESULTS: The mean-max CIMT was 0.916±0.129mm (minimum 0.630mm, maximum 1.28mm) and the mean-mean CIMT was 0.743±0.110mm (minimum 0.482mm, maximum 1.050mm) and mean hs-CRP was 0.191mg/dL (minimum 0.030mg/dL, maximum 5.440mg/dL). Multivariate analyses confirmed a significant association between increasing CIMT and increasing age, total and low density lipoprotein cholesterol while log-transformed hs-CRP levels showed significant association with increasing body mass index, waist circumference, high blood glucose and triglyceride levels. Our patients had good health awareness on CVD.

    CONCLUSION: Newly defined CIMT measurements and hs-CRP levels may be useful adjunctive tools to screen for atherosclerosis in the Malaysian population. It may help in refining risk stratification on top of traditional clinical assessment.
