    Objective: To investigate the prevalence of parental stress and psychological wellbeing among parents with autistic children and their associations with dimensions of support system.
    Methods: This is a preliminary cross sectional study which randomly selected parents with clinically diagnosed autistic children. Those parents who attended psycho-education session on management of autistic children at Health Psychology Unit were randomly selected to enroll in the study. Psychological wellbeing, parental stress and dimensions of support system were assessed by using the General Health Questionnaire (GHQ-28), the Parenting Stress Index (PSI) and the Provision Social Relation (PSR), respectively.
    Results: Of 52 parents with autistic children (34 female and 18 male), about 90.4% of parents had significant parenting stress, and 53.8% of parents showed clinical disturbance in psychological wellbeing. Gender (t=1.67, p=0.02) and occupation (F=4.78, p=0.01) showed statistically significant association with psychological wellbeing. No association found between other socio-demographic factors, parental stress and psychological wellbeing with dimensions of support system among parents with autistic children.
    Conclusion: Parents with autistic children have high prevalence of stress and psychological disturbances. Interactions of various factors need to be acknowledged and considered in order to reduce the burden of parents with autistic children.

    Older adults, especially men and/or those with diabetes, hypertension, and/or obesity, are prone to severe COVID-19. In some countries, older adults, particularly those residing in nursing homes, have been prioritized to receive COVID-19 vaccines due to high risk of death. In very rare instances, the COVID-19 vaccines can induce anaphylaxis, and the management of anaphylaxis in older people should be considered carefully. An ARIA-EAACI-EuGMS (Allergic Rhinitis and its Impact on Asthma, European Academy of Allergy and Clinical Immunology, and European Geriatric Medicine Society) Working Group has proposed some recommendations for older adults receiving the COVID-19 vaccines. Anaphylaxis to COVID-19 vaccines is extremely rare (from 1 per 100,000 to 5 per million injections). Symptoms are similar in younger and older adults but they tend to be more severe in the older patients. Adrenaline is the mainstay treatment and should be readily available. A flowchart is proposed to manage anaphylaxis in the older patients.

    Asthma, rhinitis, and atopic dermatitis (AD) are interrelated clinical phenotypes that partly overlap in the human interactome. The concept of "one-airway-one-disease," coined over 20 years ago, is a simplistic approach of the links between upper- and lower-airway allergic diseases. With new data, it is time to reassess the concept. This article reviews (i) the clinical observations that led to Allergic Rhinitis and its Impact on Asthma (ARIA), (ii) new insights into polysensitization and multimorbidity, (iii) advances in mHealth for novel phenotype definitions, (iv) confirmation in canonical epidemiologic studies, (v) genomic findings, (vi) treatment approaches, and (vii) novel concepts on the onset of rhinitis and multimorbidity. One recent concept, bringing together upper- and lower-airway allergic diseases with skin, gut, and neuropsychiatric multimorbidities, is the "Epithelial Barrier Hypothesis." This review determined that the "one-airway-one-disease" concept does not always hold true and that several phenotypes of disease can be defined. These phenotypes include an extreme "allergic" (asthma) phenotype combining asthma, rhinitis, and conjunctivitis. Rhinitis alone and rhinitis and asthma multimorbidity represent two distinct diseases with the following differences: (i) genomic and transcriptomic background (Toll-Like Receptors and IL-17 for rhinitis alone as a local disease; IL-33 and IL-5 for allergic and non-allergic multimorbidity as a systemic disease), (ii) allergen sensitization patterns (mono- or pauci-sensitization versus polysensitization), (iii) severity of symptoms, and (iv) treatment response. In conclusion, rhinitis alone (local disease) and rhinitis with asthma multimorbidity (systemic disease) should be considered as two distinct diseases, possibly modulated by the microbiome, and may be a model for understanding the epidemics of chronic and autoimmune diseases.

    Purpose: The aim of this study was to develop a substantive theory that explains parenting stress among mothers of deaf or hard-of-hearing (D/HH) children.

    Method: Fifteen hearing mothers of children with severe-to-profound sensorineural hearing loss were interviewed. Interviews were transcribed verbatim, and a grounded theory approach was used to inductively analyze parental stress in mothers of D/HH children. Theory generation was achieved through triangulation of data sources and systematic organization of data into codes. The coding process identified salient themes that were constantly cross-checked and compared across data to further develop categories, properties, and tentative hypotheses.

    Results: In general, two main themes emerged from the interviews: the contextual stressors and stress-reducing resources. The contextual stressors were labeled as distress over audiology-related needs, pressure to acquire new knowledge and skills, apprehension about the child's future, and demoralizing negative social attitudes. The stress-reducing resources that moderated parenting stress were identified to be the child's progress, mother's characteristics, professional support, and social support. The interaction between the identified stressors and adjustment process uncovered a central theme termed maternal coherence.

    Conclusion: The substantive theory suggests that mothers of D/HH children can effectively manage parenting stress and increase well-being by capitalizing on relevant stress-reducing resources to achieve maternal coherence.

    The use of a polymer inclusion membrane (PIM) as a sensing material is a new approach to overcome the selectivity and stability drawbacks of the optical chemical sensor (optode). In this study, non-plasticized PIM containing poly(vinyl chloride) as a support base, sodium morin-5-sulfonate (NaMSA) as a reagent and Aliquat 336 as a fixed carrier (ionophore) was prepared and its performance was tested for application in an optode to determine Al3+ ions. The results showed that PIM properties are greatly influenced by the membrane composition. The studies revealed that the optode response was dependent on film thickness, the presence of plasticizer, stirring effect, concentration of NaMSA, concentration of Aliquat 336 and pH of the aqueous solution used. The dynamic range of Al3+ ions concentration determined using this optode was linear from 5.19 × 10-7 to 6.00 × 10-5 mol L-1 and the calculated limit of detection (L.O.D.) was found to be 4.07 × 10-7 mol L-1. The maximum emission wavelength (λem) for the PIM based optode was 512 nm. Scanning electron microscopy analysis of the PIM revealed that a dense texture was formed. Fourier transform infra-red and thermal gravimetry analysis characterizations proved that all of the constituents of the PIM remain within the membrane. The PIM developed in this work was found to be stable, has good mechanical strength, and is sensitive and reusable. Lastly, the PIM was successfully applied as an optical sensor for determination of Al3+ ions in an aqueous solution.

    The stacked-film immobilization of 3-methyl-2-benzothiazolinone hydrazone (MBTH) in hybrid nafion/sol-gel silicate film and horseradish peroxidase (HRP) in chitosan, performed in order to allow the determination of phenolic compounds, was investigated via an optical method. The stacked films were deposited onto a microscope glass slide by a spin-coating technique. The quinone or free radical product formed by the enzymatic reactions of phenolic compounds interacts with MBTH to form azo-dye products, which can be measured spectrophotometrically at a wavelength of 500 nm. The color intensity of the product was found to increase in proportion to the phenolic concentration after 5 min of exposure. The response of the biosensor was linear over concentration ranges of 0.025-0.500, 0.010-0.070 and 0.050-0.300 mM for guaiacol, resorcinol and o-cresol, respectively, and gave detection limits of 0.010, 0.005 and 0.012 mM. The sensor exhibited good sensitivity and stability for at least two months.

    An optical biosensor based on glutamate dehydrogenase (GLDH) immobilized in a chitosan film for the determination of ammonium in water samples is described. The biosensor film was deposited on a glass slide via a spin-coating method. The ammonium was measured based on beta-nicotinamide adenine dinucleotide (NADH) oxidation in the presence of alpha-ketoglutaric acid at a wavelength of 340 nm. The biosensor showed optimum activity at pH 8. The optimum chitosan concentrations and enzyme loading were found to be at 2% (w/v) and 0.08 mg, respectively. Optimum concentrations of NADH and alpha-ketoglutaric acid both were obtained at 0.15 mM. A linear response of the biosensor was obtained in the ammonium concentration range of 0.005 to 0.5 mM with a detection limit of 0.005 mM. The reproducibility of the biosensor was good, with an observed relative standard deviation of 5.9% (n=8). The biosensor was found to be stable for at least 1 month when stored dry at 4 degrees C.

    Electrochemical biosensors for phenolic compound determination were developed by immobilization of tyrosinase enzyme in a series of methacrylic-acrylic based biosensor membranes deposited directly using a photocuring method. By modifying the hydrophilicity of the membranes using different proportions of 2-hydroxyethyl methacrylate (HEMA) and butyl acrylate (nBA), we developed biosensor membranes of different hydrophilic characters. The differences in hydrophilicity of these membranes led to changes in the sensitivity of the biosensors towards different phenolic compounds. In general biosensors constructed from the methacrylic-acrylic based membranes showed the poorest response to catechol relative to other phenolic compounds, which is in contrast to many other biosensors based on tyrosinase. The decrease in hydrophilicity of the membrane also allowed better selectivity towards chlorophenols. However, phenol biosensors constructed from the more hydrophilic membrane materials demonstrated better analytical performance towards phenol compared with those made from less hydrophilic ones. For the detection of phenols, these biosensors with different membranes gave detection limits of 0.13-0.25 microM and linear response range from 6.2-54.2 microM phenol. The phenol biosensors also showed good phenol recovery from landfill leachate samples (82-117%).

    Lipase from Candida rugosa was immobilized by entrapment on poly(N-vinyl- 2-pyrrolidone-co-2-hydroxyethyl methacrylate) (poly[VP-co-HEMA]) hydrogel, and divinylbenzene was the crosslinking agent. The immobilized enzymes were used in the esterification reaction of oleic acid and butanol in hexane. The activities of the immobilized enzymes and the leaching ability of the enzyme from the support with respect to the different compositions of the hydrogels were investigated. The thermal, solvent, and storage stability of the immobilized lipases was also determined. Increasing the percentage of composition of VP from 0 to 90, which corresponds to the increase in the hydrophilicity of the hydrogels, increased the activity of the immobilized enzyme. Lipase immobilized on VP(%):HEMA(%) 90:10 exhibited the highest activity. Lipase immobilized on VP(%):HEMA(%) 50:50 showed the highest thermal, solvent, storage, and operational stability compared to lipase immobilized on other compositions of hydrogels as well as the native lipase.

    Electroencephalographic signal is a representative signal that contains information about brain activity, which is used for the detection of epilepsy since epileptic seizures are caused by a disturbance in the electrophysiological activity of the brain. The prediction of epileptic seizure usually requires a detailed and experienced analysis of EEG. In this paper, we have introduced a statistical analysis of EEG signal that is capable of recognizing epileptic seizure with a high degree of accuracy and helps to provide automatic detection of epileptic seizure for different ages of epilepsy. To accomplish the target research, we extract various epileptic features namely approximate entropy (ApEn), standard deviation (SD), standard error (SE), modified mean absolute value (MMAV), roll-off (R), and zero crossing (ZC) from the epileptic signal. The k-nearest neighbours (k-NN) algorithm is used for the classification of epilepsy then regression analysis is used for the prediction of the epilepsy level at different ages of the patients. Using the statistical parameters and regression analysis, a prototype mathematical model is proposed which helps to find the epileptic randomness with respect to the age of different subjects. The accuracy of this prototype equation depends on proper analysis of the dynamic information from the epileptic EEG.

    INTRODUCTION: Published literature on vision impairment and cognitive function amongst older Malaysians remains scarce. This study investigates the association between vision impairment and cognitive function in an older Malaysian population.

    METHODS: Subjects aged 55 years and above from the Malaysian Elders Longitudinal Research (MELoR) study with available information on vision and Montreal Cognitive Assessment (MoCA) scores were included. Data were obtained through a home-based interview and hospital-based health check by trained researchers. Visual acuity (VA) was assessed with logMAR score with vision impairment defined as VA 6/18 or worse in the better-seeing eye. Cognition was evaluated using the MoCA-Blind scoring procedure. Those with a MoCA-Blind score of <19/22 were considered to have cognitive impairment.

    RESULTS: Data was available for 1144 participants, mean (SD) age = 68.57 (±7.23) years. Vision impairment was present in 143 (12.5 %) and 758 (66.3 %) had MoCA-Blind score of <19. Subjects with vision impairment were less likely to have a MoCA-Blind score of ≥19 (16.8 % vs 36.2 %, p < 0.001). Vision impairment was associated with poorer MoCA-Blind scores after adjustments for age, gender, and ethnicity (β = 2.064; 95 % CI, -1.282 to 3.320; P = 0.003). In those who had > 6 years of education attainment, vision impairment was associated with a significant reduction of cognitive function and remained so after adjustment for age and gender (β = 1.863; 95 % CI, 1.081-3.209; P = 0.025).

    CONCLUSION: Our results suggest that vision impairment correlates with cognitive decline. Therefore, maintaining good vision is an important interventional strategy for preventing cognitive decline in older adults.

    Low vision and blindness are major health issues affecting ageing population. This cross-sectional study aims to determine the prevalence of visual impairment (VI) in Petaling Jaya North, Petaling Jaya South, and Lembah Pantai using data from the Malaysian Elders Longitudinal Research. There were 1322 participants aged ≥55 years selected by random sampling from parliamentary electoral rolls. Visual acuity was assessed using the logarithm of the minimum angle of resolution chart at 4 m distance. The overall population-adjusted prevalence of VI was 9.0%. The estimated prevalence of VI was highest in Malays followed by Indians and Chinese. Following adjustments for ethnic discrepancies in age, marital status, education level, gender and medical illness, the Malay ethnicity remained an independent association for VI. Education level was associated with Indian ethnicity. In conclusion, the Malay ethnicity and lower education level among Indian ethnicity were found to be associated with VI among the older population in Malaysia. The Malay ethnicity showed the highest prevalence of VI followed by Indians and Chinese.

    INTRODUCTION: This study aimed to examine the role of social support and depression in predicting the quality of life among the elderly living in a rural Federal Land Development Authority (FELDA) community in Malaysia.
    METHODS: A total of 162 elderly settlers of FELDA Sungai Tengi, aged 60 years and above, were selected by universal sampling method in this cross-sectional study. Three standardized instruments - the 12-item Short Form (SF-12), 15-item Geriatric Depression Scale (GDS-15) and Medical Outcome Study Social Support (MOS-Social Support) - were used to assess for quality of life, depression and social support.
    RESULTS: Quality of life of the elderly people in this community was high, especially in terms of physical components as compared to mental components. The mean scores for emotional role in the SF-12 was relatively the highest (90.74 ± 21.59) with social functioning being the lowest (30.35 ± 22.29). The results also showed that the mean value was higher for physical component summary (74.40) as compared to mental component summary (51.51). Approximately 23.5% suffered mild depression and only 2.5% had severe depression.
    DISCUSSION: This study showed that the elderly FELDA settlers have a high quality of life, mainly on the physical components of life and low rate of severe depression, a positive indicator of their psychological well-being. Social support in the form of emotional/informational support, and depression were significant factors related to their good quality of life.

    INTRODUCTION: Loneliness has long been known to have strong association with depression. The relationship between loneliness and depression, however, has been associated with other risk factors including social support. The aim of this paper is to describe the role of social support in the association between loneliness and depression.
    METHODS: This cross-sectional study examined the mediating effects of social support among 161 community-based elderly in agricultural settlement of a rural area in Sungai Tengi, Malaysia. Subjects were investigated with De Jong Gierveld Loneliness Scale, Geriatric Depression Scale and Medical Outcome Survey Social Support Survey. Data were analyzed using Pearson correlation, linear and hierarchical regression.
    RESULTS: Results indicated that social support partially mediated the relationship between loneliness and depression.
    DISCUSSION: This suggests that social support affects the linear association between loneliness and depression in the elderly.

    INTRODUCTION: Testicular cancer (TC) incidence is increasing worldwide. This study aimed to investigate Saudi nursing students' knowledge and perception about TC.

    METHOD: This cross-sectional study was done using convenience sampling method. In this study, 280 nursing students from different nursing schools in six cities of Saudi Arabia were recruited. A structured self-report questionnaire was used to collect data.

    RESULT: About 49.2% of the participants received education about TC in their nursing schools. The findings showed lack of enough knowledge about TC among Saudi nursing students. Mostly, the participants reported that heredity factor and having family history of TC (48.9%) and age between 56 and 70 years (41.8%) were the most common risk factors of TC. According to the participants, physical examination was the most common diagnostic test usually used for early detection of TC (40.4%) and biopsy test was the most accurate test to confirm TC diagnosis (45.4%). Only one third of the participants (34.6%) knew that between 75% and 100% of TC cases can be cured in case of early detection. About half of the participants (51.8%) reported that surgical procedure was the most common treatment for TC. The nursing students who had high GPA (r=0.86, p<0.001), were unwilling to get more information on TC (r=0.24, p=0.04), had family history of TC (r= 0.53, p=0.02), medical problems with testicles (r= 0.69, p=0.01), received education about TC in their school of nursing (r=0.65, p=0.02), and were more self-confident in assessing and managing TC (r=0.38, p=0.03) had higher level knowledge about TC.  Conclusion: Despite the importance of nurses' roles in assessing and managing TC, nursing students in Saudi Arabia still did not have enough knowledge about TC. Improving nursing programs' curricula and conducting health education programs are recommended.

    OBJECTIVE: The caregivers of children diagnosed with acute lymphoblastic leukaemia (ALL) are believed to experience post-traumatic stress symptoms (PTSS), depression and anxiety. This present study endeavoured to explore the prevalence and predictors of PTSS, depression, and anxiety among the caregivers of children with ALL.

    METHODS: Purposive sampling was used to select the 73 caregivers of children with ALL who participated in this cross-sectional study. The Post-traumatic Stress Disorder Checklist for DSM-5 (PCL-5), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) were used to measure psychological distress.

    RESULT: There was a low prevalence (11%) of post-traumatic stress disorder (PTSD) among the participants. Although all the criteria for PTSD were not met, a few post-traumatic symptoms remained, suggesting that PTSS was likely present. Most of the participants reported minimal symptoms of depression (79.5%) and anxiety (65.8%). Anxiety, depression, and ethnicity predicted the PTSS scores (R2 = .77, p =.000). Subsequently, depression predicted the PTSS scores (R2 = 0.42, p =0.000). Participants of 'Other' or 'Indigenous' ethnicity had lower PTSS scores and higher anxiety scores (R2 = 0.75, p =0.000) than participants of Malay ethnicity.

    CONCLUSION: The caregivers of children with ALL experience post-traumatic stress symptoms (PTSS), depression, and anxiety. These variables co-exist and may have different trajectories in different ethnic groups. Therefore, healthcare providers should take ethnicity and psychological distress into consideration when providing paediatric oncology treatment and care.

    OBJECTIVE: The main purpose of this study was to identify the psychometric properties and validate   the Bahasa Malaysia version of the Brief Illness Perception Questionnaire among patients with cancer.

    METHODS: A total of 129 newly diagnosed patients with cancer were consecutively sampled. Reliability and validity of the questionnaire were tested using translation validity, test-retest reliability, Principal Component Analysis, Cronbach's alpha coefficient for domains and item-total correlation.

    RESULTS: The questionnaire indicates excellent test-retest reliability. The Principal Component Analysis (PCA) revealed that Kaiser-Meyer-Olkin (KMO) is 0.60 for the two-factor structure of the Brief Illness Perception Questionnaire of the Bahasa Malaysia version which consists of cognitive illness representation and emotional illness representation.

    CONCLUSION: The Brief Illness Perception Questionnaire in the Bahasa Malaysia version is a useful tool to use among patients with cancer in Malaysia context despite moderate psychometric properties. This is based on the premise that the questionnaire can be used as a quick tool to assess illness perceptions among Malaysian with cancer in routine oncology practice.
