    The elderly population in Malaysia is growing rapidly. Some of the most vulnerable are in residential care. Research is needed into the characteristics of this population to aid clinicians and policy makers in addressing the needs of this group. This observational, cross-sectional study aims to determine prevalence of undetected cognitive impairment and depression in elderly care home residents in Malaysia. One hundred and sixty-seven people over 60 years of age living in a state run residential home were interviewed. Validated assessment tools were used to measure dependency, cognitive impairment and depression. The prevalence of probable dementia is 36.5%, with increasing prevalence with age and level of dependence. Prevalence of depression is 67.0% (major depression 13.2%), with more depression in males and in the Indian population. None of the identified cases had been previously investigated or treated for dementia or depression.

    BACKGROUND: Despite the clear stand taken by the United Nations (UN) and other international bodies in ensuring that female genital cutting (FGC) is not performed by health professionals, the rate of medicalization has not reduced. The current study aimed to determine the extent of medicalization of FGC among doctors in Malaysia, who the doctors were who practiced it, how and what was practiced, and the motivations for the practice.

    METHODS AND FINDINGS: This mixed method (qualitative and quantitative) study was conducted from 2018 to 2019 using a self-administered questionnaire among Muslim medical doctors from 2 main medical associations with a large number of Muslim members from all over Malaysia who attended their annual conference. For those doctors who did not attend the conference, the questionnaire was posted to them. Association A had 510 members, 64 male Muslim doctors and 333 female Muslim doctors. Association B only had Muslim doctors; 3,088 were female, and 1,323 were male. In total, 894 questionnaires were distributed either by hand or by post, and 366 completed questionnaires were received back. For the qualitative part of the study, a snowball sampling method was used, and 24 in-depth interviews were conducted using a semi-structured questionnaire, until data reached saturation. Quantitative data were analysed using SPSS version 18 (IBM, Armonk, NY). A chi-squared test and binary logistic regression were performed. The qualitative data were transcribed manually, organized, coded, and recoded using NVivo version 12. The clustered codes were elicited as common themes. Most of the respondents were women, had medical degrees from Malaysia, and had a postgraduate degree in Family Medicine. The median age was 42. Most were working with the Ministry of Health (MoH) Malaysia, and in a clinic located in an urban location. The prevalence of Muslim doctors practising FGC was 20.5% (95% CI 16.6-24.9). The main reason cited for practising FGC was religious obligation. Qualitative findings too showed that religion was a strong motivating factor for the practice and its continuation, besides culture and harm reduction. Although most Muslim doctors performed type IV FGC, there were a substantial number performing type I. Respondents who were women (adjusted odds ratio [aOR] 4.4, 95% CI 1.9-10.0. P ≤ 0.001), who owned a clinic (aOR 30.7, 95% CI 12.0-78.4. P ≤ 0.001) or jointly owned a clinic (aOR 7.61, 95% CI 3.2-18.1. P ≤ 0.001), who thought that FGC was legal in Malaysia (aOR 2.09, 95% CI 1.02-4.3. P = 0.04), and who were encouraged in religion (aOR 2.25, 95% CI 3.2-18.1. P = 0.036) and thought that FGC should continue (aOR 3.54, 95% CI 1.25-10.04. P = 0.017) were more likely to practice FGC. The main limitations of the study were the small sample size and low response rate.

    CONCLUSIONS: In this study, we found that many of the Muslim doctors were unaware of the legal and international stand against FGC, and many wanted the practice to continue. It is a concern that type IV FGC carried out by traditional midwives may be supplanted and exacerbated by type I FGC performed by doctors, calling for strong and urgent action by the Malaysian medical authorities.

    Background: Given background sparsity of country-specific literature evidence, and the pervasive unhealthy lifestyle habits such as tobacco, alcohol use, and high sugar consumption among fishermen, the aim of this study was to assess the oral health status and associated lifestyle factors among Malaysian fishermen in Teluk Bahang, Penang.

    Subjects and Methods: In an analytical cross-sectional design, we used simple random sampling technique to select 242 multiracial Malaysian male fishermen aged between 18 and 75 years from five fishing villages located at Gurney Drive, Tanjong Tokong, Tanjong Bungah, Batu Ferringhi, and Teluk Bahang to participate in this study. During four consecutive weekends in January 2017, we conducted face-to-face interviews with participants using a pre-validated, interviewer-administered WHO oral health questionnaire. We categorized participants as having "good" or "poor" oral health based on a mean cutoff score of 14. Multivariate regression models were fitted to assess the oral health status and associated lifestyle factors among the study population, using SPSS version 22.

    Results: We achieved a response rate of 97.6%. Overall, the prevalence of poor oral health in this study was 47.5%. "Income" (RM/month), "type of fishing," "additional occupation," "age" (years), "frequency of pies, buns consumed," and "frequency of sweets, soft drinks consumed" were significant predictors of oral health status among the fishermen.

    Conclusion: Poor oral health is relatively highly prevalent among the fishermen in our study. The oral health status of fishermen in Teluk Bahang was consistent with the national average and significantly associated with their sociodemographic and lifestyle factors. Targeted interventions are required to arrest and reverse this trend.

    INTRODUCTION: Social support and self-efficacy are factors that influence patients' health behaviour. However, the relationship between these two factors among patients with Type 2 Diabetes Mellitus (T2DM) has not been adequately explored. This study aims to report social support and selfefficacy of Malaysian T2DM patients, and their correlations.

    METHODS: This cross-sectional questionnaire study involved 329 patients with T2DM who received their follow up at a public primary care clinic. Patients were selected via systematic random sampling. Patients self-completed locally adapted versions of the Medical Outcomes Study (MOS) Social Support Survey and Diabetic Management Self Efficacy Scale (DMSES). The scores of both tools were analysed to determine the association and correlation between social support and self-efficacy.

    RESULTS: The mean score for overall social support was 72.7±21.40 score range (0-100). "Affectionate support" was rated the highest averaged mean score at 78.31±23.71 (score range: 0-100). The mean DMSES score was 147.6±35.5 (score range :0-200), of which "medications" subscale was rated the highest with averaged mean scores 9.07±1.67 (score range: 0-10). Overall social support and self-efficacy were found to be weakly correlated (r=0.197, p<0.001). However, all subscales of social support were moderately correlated with "medications" subscale of self-efficacy.

    CONCLUSION: Social support is significantly associated with patients' self-efficacy in handling their own medications.

    INTRODUCTION: Thalassemias are the most common human monogenic disorders in the world. Regular blood transfusion and increased intestinal absorption of iron among thalassemia patients will lead to iron overload, which will not only markedly decrease their life expectancy but also pose a heavy burden to the healthcare system. The objective of this study was to evaluate the level of knowledge, attitude and practice towards dietary iron among thalassemia patients and their caregivers.

    METHODS: An analytical cross-sectional study using purposive sampling method was conducted at eight thalassemia societies in Peninsular Malaysia. 260 respondents comprised of patients and caregivers were assessed with two separate sets of questionnaires.

    RESULTS: Knowledge on dietary iron among the respondents was unsatisfactory, despite them having good knowledge on thalassemia disorder. Female patients were found to have better dietary knowledge, attitude and practice compared to males. The percentage of caregivers with good attitude and good practice were significantly higher compared to adult patients. Caregivers with children on iron chelators were noted to have better dietary attitude and practice. Thalassemia knowledge and children on vitamins were found to be the predictors of dietary knowledge among the patients and caregivers respectively.

    CONCLUSION: The level of knowledge on dietary iron among the patients and caregivers was unsatisfactory in spite of their attitude and practice towards dietary iron were good. Effective delivery of dietary information to the patients and caregivers is essential to enable them to choose a healthy diet for their condition.

    BACKGROUND: Mental illness-related stigma is common, and is associated with poorer outcomes in people with mental illness. This study evaluated the attitudes of primary care nurses towards people with mental illness and its associated factors; and the effectiveness of a short video-based contact intervention (VBCI) in improving these attitudes using a Malay version of the 15-item Opening Minds Stigma Scale for Healthcare Providers (OMS-HC-15-M).

    METHODS: A 5-minute VBCI was developed comprising elements of psychoeducation and interviews of people with mental illness and the people they interact with, relating to experience of mental illness and recovery. A pre-post cross-sectional study was conducted on 206 randomly selected primary care nurses in Penang, Malaysia. The OMS-HC-15-M questionnaire was administered before and immediately after participants viewed the VBCI. The difference in mean pre-post VBCI scores using paired t-tests, effect size and standardised response mean (SRM) were obtained. Factors correlating to attitudes were obtained using univariate and multivariate regression analyses.

    RESULTS: Differences in pre-post VBCI score were statistically significant (p<0.001) with a 14% score reduction, a moderate effect size and SRM at 0.97 (0.85-0.11) and 1.1 (0.97-1.2) respectively. By factoring in the Minimal Detectable Change statistic of 7.76, the VBCI produced a significant improvement of attitudes in 30% of the participants. Factors associated with less stigmatising attitudes at baseline were previous psychiatry-related training, desiring psychiatric training, and positive contact with people with mental illness.

    CONCLUSIONS: This is the first study in Malaysia to show that a brief VBCI is effective in improving attitudes of primary care nurses towards people with mental illness in the immediate term. Further studies are needed to determine if these results can be sustained in the longer term and generalizable to other health care professionals. Qualitative studies are warranted to provide insight to the factors correlating to these attitudes. (300 words).

    Diabetic ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus in children. Despite the presence of dehydration, hypertension occurs in a significant proportion of children with DKA. There is a lack of clarity in the literature regarding the management of hypertension in patients with paediatric DKA. Herein, we report the case of an adolescent boy who presented with DKA and severe hypertension. His neurological status was closely monitored. There was a gradual decline in his blood pressure with an improvement in the pH over the next 72 hours. The combination of severe DKA and hypertension can be a challenging clinical dilemma, especially regarding fluid management. Studies on severe DKA in children are exacting, given the rarity of this condition. A multi-centre study is suggested to provide a meaningful analysis of this aspect of DKA.

    Transgender topics are controversial in Malaysia and trans people are subject to stigma and persecution. In this study context, the transition is defined as a phase where a person changes from one gender to the gender that an individual chooses. Little is known about the transgender people's transition experiences in Malaysia. Studies have shown that transition helps boost transgender individuals in most aspects. This study seeks to understand the transition experiences of the Malay Muslim Trans women in Northern Malaysia. A qualitative study using a snowball sampling method was used to interview in-depth 13 trans women. The interviews focused on their gender transition experiences, support systems, family and friends' reactions, and coping strategies. The study found four primary themes: transition, reaction, support system, and coping method. Most of the respondents agreed that they felt conflicted about their gender at a young age and started transitioning when they were adolescents. Overall acceptance and reaction of family and society to their transition was low and not good. Most mentioned the importance of a good support system and that they received essential support from their peers in the transgender community. However, they acknowledged that family support was also crucial for them. All of the respondents specified that they did not regret their gender transition. Although this study gained insight, more is needed to understand in depth a very sensitive subject such as this.

    Water-in-diesel emulsion (WiDE) is an alternative fuel for CI engines that can be employed with the existing engine setup with no additional engine retrofitting. It has benefits of simultaneous reduction of both NO x and particulate matters in addition to its impact in the combustion efficiency improvement, although this needs further investigation. This review paper addresses the type of emulsion, the microexplosion phenomenon, emulsion stability and physiochemical improvement, and effect of water content on the combustion and emissions of WiDE fuel. The review also covers the recent experimental methodologies used in the investigation of WiDE for both transport and stationary engine applications. In this review, the fuel injection pump and spray nozzle arrangement has been found to be the most critical components as far as the secondary atomization is concerned and further investigation of the effect of these components in the microexplosion of the emulsion is suggested to be center of focus.

    Quantum computing is a computer development technology that uses quantum mechanics to perform the operations of data and information. It is an advanced technology, yet the quantum channel is used to transmit the quantum information which is sensitive to the environment interaction. Quantum error correction is a hybrid between quantum mechanics and the classical theory of error-correcting codes that are concerned with the fundamental problem of communication, and/or information storage, in the presence of noise. The interruption made by the interaction makes transmission error during the quantum channel qubit. Hence, a quantum error correction code is needed to protect the qubit from errors that can be caused by decoherence and other quantum noise. In this paper, the digital system design of the quantum error correction code is discussed. Three designs used qubit codes, and nine-qubit codes were explained. The systems were designed and configured for encoding and decoding nine-qubit error correction codes. For comparison, a modified circuit is also designed by adding Hadamard gates.

    Today, disease detection automation is widespread in healthcare systems. The diabetic disease is a significant problem that has spread widely all over the world. It is a genetic disease that causes trouble for human life throughout the lifespan. Every year the number of people with diabetes rises by millions, and this affects children too. The disease identification involves manual checking so far, and automation is a current trend in the medical field. Existing methods use a single algorithm for the prediction of diabetes. For complex problems, a single model is not enough because it may not be suitable for the input data or the parameters used in the approach. To solve complex problems, multiple algorithms are used. These multiple algorithms follow a homogeneous model or heterogeneous model. The homogeneous model means the same algorithm, but the model has been used multiple times. In the heterogeneous model, different algorithms are used. This paper adopts a heterogeneous ensemble model called the stacked ensemble model to predict whether a person has diabetes positively or negatively. This stacked ensemble model is advantageous in the prediction. Compared to other existing models such as logistic regression Naïve Bayes (72), (74.4), and LDA (81%), the proposed stacked ensemble model has achieved 93.1% accuracy in predicting blood sugar disease.

    Chemotherapeutic drugs have demonstrated effectiveness in treating various neoplastic conditions; however, they can also have detrimental effects on male gonadal function and fertility. Consequently, interest has grown in identifying novel approaches that can mitigate chemotherapy-induced testicular damage. Thymoquinone (TQ), the chief active component of the volatile oil of Nigella sativa (NS), has a wide range of therapeutic properties, including antioxidant, anti-inflammatory and anti-apoptotic effects. The aim of this systematic review was to identify experimental animal studies that have evaluated the protective effects of TQ against testicular complications associated with chemotherapy. In accordance with the preferred reporting items for systematic review and meta-analyses (PRISMA) guidelines, a thorough search was performed across several databases (PubMed, EBSCOhost, Sage and Scopus) to identify experimental studies published from 2010 to May 2022 that focused on rodent models and compared the effects of TQ versus other chemotherapeutic drugs. Eight studies met the inclusion criteria, comparing TQ with methotrexate (MTX), 6-mercaptopurine (6-MP), cyclophosphamide (CPA), bleomycin (BL), doxorubicin (DOX) or busulfan (BUS). The results of these studies consistently demonstrated that TQ significantly improved sperm parameters, the levels of oxidative stress (OS) markers, apoptosis markers, and hormones and testicular histopathology, indicating that TQ has protective effects against chemotherapy-induced damage. TQ mitigated chemotherapy-induced testicular toxicity by decreasing lipid peroxidation and enhancing the activity of antioxidant enzymes within chemotherapy-treated testes. These findings highlight the potential of TQ as a therapeutic agent that can ameliorate testicular complications associated with chemotherapy, thereby providing a basis for further research and potential therapeutic applications.

    This cross sectional survey was conducted to determine the support in making Penang UNESCO World Heritage Site (GTWHS) smoke free and to determine the influence of tolerance towards smoking on this support. This is the first phase in making Penang, Malaysia a smoke free state. A multistage sampling process was done to select a sample of respondents to represent the population of GTWHS. Attitude towards smoking was assessed using tolerance as a proxy. A total of 3,268 members of the community participated in the survey. A big majority (n = 2969; 90.9%) of the respondents supported the initiative. Support was lowest among the owners and residents/tenants, higher age groups, the Chinese, men, respondents who had poor knowledge of the places gazetted as smoke free, and respondents with poor knowledge of the health effects on smokers and on passive smokers. The odds (both adjusted and unadjusted) of not supporting the initiative was high among those tolerant to smoking in public areas. Tolerance towards smoking was associated with 80.3% risk of non-support in the respondents who were tolerant to smoking and a 57.2% risk in the population. Health promotion and education concerning the harm of tobacco smoke in Malaysia, which has mainly targeted smokers, must change. Health education concerning the risks of second hand smoke must also be given to non-smokers and efforts should be made to denormalize smoking.

    In this paper, a numerical method for the solution of a strongly coupled reaction-diffusion system, with suitable initial and Neumann boundary conditions, by using cubic B-spline collocation scheme on a uniform grid is presented. The scheme is based on the usual finite difference scheme to discretize the time derivative while cubic B-spline is used as an interpolation function in the space dimension. The scheme is shown to be unconditionally stable using the von Neumann method. The accuracy of the proposed scheme is demonstrated by applying it on a test problem. The performance of this scheme is shown by computing L∞ and L2 error norms for different time levels. The numerical results are found to be in good agreement with known exact solutions.

    Nylon denture base material could be a useful alternative to poly (methyl methacrylate) (PMMA) in special circumstances such as patient allergy to the monomer. The aim of this study was to evaluate the flexural properties of a nylon denture base material (Lucitone FRS), a conventional compression-moulded heat-polymerized (Meliodent), a compression-moulded microwave-polymerized (Acron MC) and an injection-moulded microwave-polymerized (Lucitone 199) PMMA polymers. The effect of aldehyde-free, oxygen releasing disinfectant solution (Perform) on these properties was also investigated. The flexural modulus and the flexural strength were assessed with a three-point bending test. Specimens were stored in water at a temperature of 37 degrees C for 30 days. For each material, half of the prepared specimens were randomly selected and immersed in the disinfectant 24 h prior to testing. Results were compared statistically at a confidence level of 95%. The result showed that in both the control and disinfected groups, the flexural modulus of nylon was significantly lower than the three PMMA polymers. The flexural strength of nylon was significantly lower than those of Meliodent and Acron MC but was comparable with Lucitone 199. A 24-h immersion in the disinfecting solution increased the rigidity of nylon denture base material.

    Introduction: Fluorosis has been associated with an increased risk of degenerative changes in the knee. Multiple studies have found an association between arthritis and elevated fluoride levels. We aim to delineate if elevated fluoride level has any direct correlation with the degree of radiological grading and clinical symptoms in knee arthritis.

    Materials and Methods: A cross-sectional study of 80 knee arthritis patients was conducted from February 2017 to April 2018. Serum fluoride levels were measured and patient's pain scores, WOMAC scores and radiological grading were correlated with the elevated fluoride levels.

    Results: In our study, 30 out of 80 patients had increased serum fluoride level. Statistically significant differences were noted in VAS score, WOMAC score and Kellgren and Lawrence radiological grades between patients with normal serum fluoride level and those with elevated fluoride level.

    Conclusion: There is an increased risk of knee arthritis in patients with elevated blood fluoride levels and patients with increased fluoride levels are associated with more severe symptoms and radiographic disease.

    Tardy ulnar nerve palsy is a known complication of cubitus valgus. The options for treating the ulnar neuropathy include anterior nerve transposition or neurolysis. We report on an 11-year-old boy who had a tardy ulnar nerve palsy due to cubitus valgus resulting from a non-union of a lateral condyle fracture of the humerus. Anterior transposition of the ulnar nerve was not done after the closing wedge osteotomy of the distal humerus. The close wedge osteotomy relieved the tension on the nerve and not transposing the ulnar nerve anteriorly prevented an iatrogenic nerve injury. The patient had no restriction with activities of daily living at the six years follow-up although neurological recovery was incomplete.

    Femoral neck stress fractures are rare in children. To the best of our knowledge, the tension type stress fracture has been reported only twice in the English language literature. We report on a five years follow-up of a 10-year-old boy with this injury which was initially missed. The fracture healed after screw fixation. We highlight the importance of considering stress fracture as a differential diagnosis in a child with chronic hip pain. A careful physical examination and the appropriate imaging will avoid missing the diagnosis.

    Online activities have become the norm. From searching for new information to conducting business meetings, social media's role in daily life continues to grow in prominence. It is estimated that the majority of the population uses social media, and users include doctors and other healthcare professionals. It is critical for primary care doctors to note how social media can substantially influence one's healthcare behaviour and decision making. Because primary care doctors are usually the first line of contact for patients, they are the most easily accessible and most instrumental in using social media to steer the public toward proper information on healthcare.
