Rapid-response RNA-fluorescence in situ hybridization (FISH) assay platform for coronavirus antiviral high-throughput screening

Over the past 25 years, the global community has faced challenges posed by three distinct outbreaks of coronaviruses including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The identification of a novel alphacoronavirus canine CoV (CCoV-HuPn2018) in human patients in Malaysia underscores the potential for crossover infections to humans. The threat of the ever-evolving nature of viral infections as well as the lingering health and socioeconomic effects of the recent SARS-CoV-2 pandemic emphasize the urgent need for advanced antiviral drug screening tools that can be quickly implemented to strengthen preparedness and preventive measures against future outbreaks. Here, we present the development and validation of a novel RNA-fluorescence in situ hybridization (FISH) imaging assay as a 384-well, high-throughput rapid response platform for antiviral drug discovery. RNA-FISH is a powerful tool to visualize specific mRNA in cultured cells using a high-content imaging platform. The flexibility of RNA-FISH probe sets allows for the rapid design of viral genome-specific probes, enabling in vitro assay development to test for inhibition of viral replication by either biologic or small molecule inhibitors. Screening of 170 antiviral compounds in concentration-response demonstrates a strong correlation between the RNA-FISH assay and an immunofluorescence assay (IFA) for both human coronaviruses HCoV-OC43 and HCoV-229E. Additionally, we successfully applied this methodology in the context of CCoV strain 1–71, proving rapid development and deployment, opening new avenues for the evaluation of antiviral drugs to potential future emerging threats.

Knowledge, Attitude and Practice of Conventional Medicine Among Thalassaemia In Malaysia: Conceptual paper

Thalassaemia is chronic hereditary blood disorder. Medication has extended patients' lifespans, but research on their quality of life is scarce due to psychological impacts and medication adherence issues. The objective is to develop and validate a survey assessing the knowledge, attitude, and practice of Malaysian thalassaemia patients towards medication. We will use an exploratory mixed-methods approach with ethical approval from UiTM. Phase I involves semi-structured interviews with thalassaemia patients. Phase II focusses on creating and validating KAP instruments with expert panels and pilot testing. The tools will help medical professionals gather data to improve treatment compliance.

Trajectory of health-related quality of life during and after hospitalisation due to worsening of heart failure.

This study aimed to examine the trajectory in health-related quality of life (HRQoL) during and after hospitalisation for worsening of heart failure (HF) in Malaysia. 200 patients with heart failure and reduced ejection fraction (HFrEF) admitted into two hospitals in Malaysia due to worsening of HF were surveyed using the EQ-5D-5L questionnaire. The primary outcomes were utility values at admission, discharge and 1-month post-discharge (1MPD). Secondary outcomes included the visual analogue scores (VAS) and the proportion of patients reporting each EQ-5D-5L dimension levels. Missing data were imputed using multiple imputation, and generalised linear mixed models were fitted. At admission, the unadjusted mean utility values and VAS scores for HFrEF patients in Malaysia were as low as 0.150 ± 0.393 and 38.2 ± 20.8, respectively. After a median hospital stay of 4 days, there was a significant improvement in utility values and VAS scores by 0.510 (95% CI: 0.455-0.564) and 28.8 (95% CI: 25.5-32.1), respectively. The utility value and VAS score at 1-month post-discharge were not significantly different from discharge. The proportion of HFrEF patients reporting problems and severe problems in mobility, self-care, usual activities, and anxiety/depression, pain/discomfort reduced at varying degree from admission to discharge and 1MPD. HF is a progressive condition with substantial variation in HRQoL during the disease trajectory. During hospitalisation due to worsening of HF, HFrEF population has unfavourable HRQoL. Rapid and significant HRQoL improvement was observed at discharge, which sustained over one month. The study findings can inform future cost-effectiveness analyses and policies.

Evaluating MCMC Convergence in a Bayesian Model of ST-Elevation Myocardial Infarction Female Patients in Malaysia

The majority of research that looked at the Bayesian Markov Chain Monte Carlo (MCMC) approach for prognostic modelling of cardiovascular disease only focused on the use of the Bayesian approach in variable selection, model selection, and prior distribution selection. But very few of this research has looked at the Markov chains' convergence in the model. In this study, convergence diagnostics were carried out to evaluate the convergence of Markov chains using both visual inspection and additional diagnostics. The National Cardiovascular Disease Database-Acute Coronary Syndrome (NCVD-ACS) registry, which included 1248 female patients with ST-Elevation Myocardial Infarction (STEMI) between 2006 and 2013, was used for this study's analysis. The multivariate Bayesian model identified six significant variables: dyslipidaemia, myocardial infarction, smoking, renal disease, Killip class, and age group. The trace plots did not reveal any distinctive patterns based on these significant variables, and the model's MCMC mixing is typically good. While for the autocorrelation plots, mild autocorrelations for age group, Killip IV, as well as the intercept term in the model. Since there were only mild autocorrelations, no thinning is needed. Also, the Geweke diagnostic showed that the chain is divided into two windows containing a set fraction of the first and last iterations which produced standard Z-scores. The Geweke diagnostic did not provide evidence of non-convergence, as none of the Z-scores fell in the extreme tails of the N (0,1). In this study, a number of plots and additional diagnostic tools showed that the Markov chains have reached convergence, which is relevant to the general use of the MCMC approach.

Practices and Barriers in Implementing the Low FODMAP Diet for Irritable Bowel Syndrome Among Malaysian Dietitians: A Qualitative Study.

The low fermentable oligo-, di-, mono-saccharides and polyols (FODMAP) diet (LFD) is a second-line dietary intervention for irritable bowel syndrome (IBS) patients, involving FODMAP restriction, reintroduction, and personalization, and it needs to be delivered by dietitians. However, the application of this diet among Malaysian IBS patients is not well understood. This study aimed to explore the practices and barriers in delivering the LFD among Malaysia dietitians. Semi-structured qualitative interviews were conducted online with practicing dietitians until the data reached saturation. All the interview sessions were audio recorded and transcribed verbatim. Thematic analysis was used to analyze the data. Eleven dietitians were interviewed, with 36.4% (n = 4) having more than 10 years of experience. The following four themes regarding their practices emerged: 1. dietary advice on FODMAP restriction; 2. duration of FODMAP restriction phase; 3. references used to get information about FODMAPs, and 4. strategies on reintroduction. Meanwhile, the following seven barriers were identified: 1. lack of culturally relevant educational materials; 2. limited knowledge about the LFD; 3. inadequate formal training among dietitians; 4. lack of integration in multi-disciplinary care; 5. low health literacy of patients; 6. low compliance rate among patients, and 7. restrictions for certain populations. LFD implementation in Malaysia is not standardized as only experienced dietitians can provide dietary evidence-based advice. Lack of training and culturally specific resources are some of the main barriers that were identified to be limiting the implementation of the diet. Therefore, there is a need for training programs and resource development to support Malaysian dietitians in managing IBS patients.

Relationship of incidence of radix entomolaris and C-shaped canal in mandibular molars using CBCT: A multi-centre study.

This study aimed to evaluate the relationship of incidence between radix entomolaris (RE) in permanent mandibular first molars (FM) with C-shaped canal (CSC) in permanent mandibular second molars (SM). A total of 1015 cone-beam computed tomography (CBCT) images of permanent mandibular molars from Malaysian patients were collected retrospectively and analysed by researchers from seven dental schools in Malaysia trained in CBCT technology. The presence and absence of RE and CSC were scored as 'yes' or 'no'. The prevalence of FM with RE was 21.2% and SM with CSC was 37.9%. The co-occurrence of RE and CSC in the same quadrant was 6.5% (OR = 1.497, p = 0.014). Female, Chinese and samples from Eastern Peninsular Malaysia were associated with CSC in SM (p < 0.05). The increased appearance of CSC in SM when RE is present in FM makes it imperative for clinicians to be vigilant during examination and diagnosis to prevent potential endodontic mishaps.

Survival of Ischaemic and Haemorrhagic Stroke: Analysis of the Malaysian National Stroke Registry Data from 2009 to 2013.

Stroke ranks as the second leading cause of death globally, contributing to 15.2 million deaths in 2016. In Malaysia, stroke has emerged as a significant cause of mortality and disability. This study aims to evaluate the survival time and rate of stroke patients in Malaysia. In this retrospective cohort study, we reviewed secondary data from the National Stroke Registry (NSR) of Malaysia. The study included all Malaysian residents over the age of 12 years old diagnosed with either ischaemic or haemorrhagic stroke between 1 January 2009 and 31 December 2013. Patients with a transient ischaemic attack were excluded. We updated the death status up to 31 December 2018 using mortality data from the Malaysian National Registry Department. We used Kaplan-Meier Survival Analysis to determine the overall median survival time and log-rank test to compare the median time by ethnicity, sex and stroke type. The survival rates at 1 year, 3 years and 5 years were obtained using the life-table method. The analysis included a total of 5,777 stroke patients. The mean age at diagnosis was 63.15 years old (with a standard deviation of 12.46 years old). The overall median survival time was 51 months (95% CI: 47.4, 54.6). Non-Malay patients and those with ischaemic strokes experienced a longer median survival time (65.2 months [95% CI: 56.6, 73.7] and 56.3 months [95% CI: 52.2, 60.3]), respectively. The survival rates at 1 year, 3 years and 5 years were 66.7% (95% CI: 65.5%, 68.0%), 55.6% (95% CI: 54.3%, 56.9%) and 46.9% (95% CI: 45.6%, 48.2%), respectively. There are significant differences in median survival time in relation to ethnicity and stroke types. Compared to other developed countries, Malaysia's 5-year survival rate is notably lower.

Reduced red blood cell deformability in vivax malaria.

Reduced deformability of both infected and uninfected red blood cells (RBC) contributes to pathogenesis in falciparum malaria. Whole blood RBC-deformability is not well-characterised in vivax malaria. We used a laser-assisted optical rotational cell analyzer to measure the RBC deformability in fresh whole blood from Malaysian patients with vivax malaria (n=25). Deformability of whole blood RBC, the vast majority of which were uninfected, was reduced in vivax malaria compared to controls (n=15), though not to the same degree as in falciparum malaria (n=90). Reduced RBC-deformability may contribute to the pathogenesis of vivax malaria, including splenic retention of uninfected RBC.

Comorbidities and Monitoring in Patients with Chronic Hepatitis B on Nucleos(t)ide Analogues Attending a Tertiary Hospital in Malaysia, Southeast Asia: A Critical Perspective.

Chronic hepatitis B (CHB) is a significant global public health concern in Malaysia. It is a potentially life-threatening liver disease caused by the hepatitis B virus (HBV), which can lead to long-term complications such as cirrhosis, liver failure and hepatocellular carcinoma. In managing CHB, nucleos(t)ide analogues (NAs) have become the preferred treatment due to their ability to suppress viral replication and prevent disease progression. The question of liver-associated comorbidities related to patients with CHB on NAs remains unresolved in Malaysia despite the impending burden of CHB in the country. This study intends to address this and related aspects. We assessed 136 CHB patients on NAs in one centre, the Hospital Universiti Sains Malaysia. Demographic and epidemiological data on the treatment, concomitant disease and monitoring strategies were collected and analysed. Patients on NAs aged 50 years old-70 years old had the highest proportion of CHB (45.59%), with males representing 61.03% of that age group. There was a statistical significance in CHB acquisition and presence of comorbidities at P > 0.005. Our cohort displayed seven comorbidities (diabetes, obesity, rheumatoid diseases, renal impairment, spontaneous bacterial peritonitis, hypertension, non-hepatocellular malignancies and carcinoma); hypertension had the highest incidence (69.12%), while renal impairment had the lowest incidence (8.09%). Whole blood count, liver function and creatinine tests were the major monitoring tests used in over 90% of the cohort compared to viral load (6.1%). Diabetes, hypertension and obesity were independent risk factors for acquiring liver cirrhosis and hepatocellular carcinoma. Malaysian CHB patients treated with NAs have several comorbidities that could affect disease outcomes. Therefore, careful monitoring is required.

Health tourism in Malaysia: understanding the drivers of satisfaction and revisit intention

ABSTRACT Medical tourism is a dynamic industry that seeks to improve satisfaction and foster loyalty among Arab medical tourists. This study delves into the complex experience of medical tourism among Arab patients in Malaysia by using an integrated analytical framework that examines the combined effects of quality perception and recovery experience on tourists’ satisfaction and intentions to revisit. Utilising a cross-sectional design with purposive sampling, the study collected responses from 432 Arab patients, employing Partial Least Squares Structural Equation Modelling (PLS-SEM) and Necessary Conditions Analysis (NCA) to analyze the data. The findings reveal that perceived quality, especially in healthcare services and post-treatment care, significantly enhances tourist satisfaction, which directly influences their intentions to revisit. Additionally, trust emerged as a critical factor that not only strengthens the relationship between satisfaction and revisit intentions but also acts as a necessary condition for achieving high satisfaction levels. This research contributes to tourism literature by detailing the specific pathways through which service quality and recovery experience impact tourist satisfaction and revisit intentions. It provides practical insights for medical tourism providers to optimise service delivery and trust-building strategies, thereby enhancing Malaysia's reputation as a premier medical tourism destination.

Development and Validation of a Malay Version Questionnaire to Evaluate Remote Health Monitoring of COVID-19 via Telehealth Applications: Navigating Telehealth Evolution.

Introduction The rapid adoption of telehealth services due to the COVID-19 pandemic has highlighted the necessity for effective tools to evaluate patient experiences. This study developed and validated the Telehealth Usability, Acceptability, and Satisfaction Questionnaire (TUASQ) for virtual COVID-19 Assessment Centres (CACs) in Malaysia, aiming to comprehensively measure usability, acceptability, and satisfaction. Methodology The TUASQ was developed in two phases. Initially, the questionnaire development phase included item generation guided by the Technology Acceptance Model (TAM) and the Health Belief Model (HBM), with feedback from a panel of six experts. Items were refined through Content Validity Index (CVI) - Item-Level Content Validity Index (I-CVI) ≥ 0.82, Scale-Level Content Validity Index (S-CVI) ≥ 0.82, and Content Validity Ratio (CVR ≥ 0.78); and Face Validity Index (FVI) by 10 respondents - Item-Level Face Validity Index (I-FVI) ≥ 0.82and Scale-Level Face Validity Index (S-FVI ≥ 0.82). The psychometric validation phase involved a cross-sectional study of 705 respondents, recruited through convenience sampling from March to July 2024, to perform Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA), followed by reliability testing using Cronbach's alpha, Composite Reliability (CR), and Average Variance Extracted (AVE). Results Content validation showed that most items' I-CVI exceeded 0.82, indicating significant expert consensus on relevance and clarity. The CVR also surpassed the 0.78 threshold, affirming their essential role. Face validation indices generally exceeded 0.80, confirming the questionnaire's clarity and comprehensiveness from the users' perspective. EFA with 250 participants indicated a high Kaiser-Meyer-Olkin Measure of Sampling Adequacy (KMO) of 0.933 and significant Bartlett's test (χ² (136) = 3752.698, p < 0.001), supporting the factorability of the data and extracting three distinct factors. CFA with 455 participants initially showed a poor fit, prompting model adjustments that subsequently improved the fit indices (Root Mean Square Error of Approximation (RMSEA) = 0.076, Standardized Root Mean Square Residual (SRMR) = 0.045, Goodness of Fit Index (GFI) = 0.94, Tucker-Lewis Index (TLI) = 0.96, Comparative Fit Index (CFI) = 0.97). Reliability testing revealed a high internal consistency with Cronbach's alpha of 0.975. CR for each factor exceeded the 0.70 threshold, and the AVE for each factor was above 0.50, indicating good convergent validity. Conclusion The validated TUASQ is a reliable and effective instrument for assessing the experiences of Malaysian patients using virtual CAC. Demonstrating robust psychometric properties through comprehensive validation processes, the TUASQ accurately measures usability, acceptability, and satisfaction, identifying strengths and areas for improvement in telehealth services. This contributes to enhanced care quality and patient satisfaction in the evolving healthcare landscape.

Post-discharge spirometry evaluation in patients recovering from moderate-to-critical COVID-19: a cross-sectional study

Understanding the prevalence of abnormal lung function and its associated factors among patients recovering from COVID-19 is crucial for enhancing post-COVID care strategies. This study primarily aimed to determine the prevalence and types of spirometry abnormalities among post-COVID-19 patients in Malaysia, with a secondary objective of identifying its associated factors. Conducted at the COVID-19 Research Clinic, Faculty of Medicine, University Technology MARA, from March 2021 to December 2022, this study included patients at least three months post-discharge from hospitals following moderate-to-critical COVID-19. Of 408 patients studied, abnormal spirometry was found in 46.8%, with 28.4% exhibiting a restrictive pattern, 17.4% showing preserved ratio impaired spirometry (PRISm), and 1.0% displaying an obstructive pattern. Factors independently associated with abnormal spirometry included consolidation on chest X-ray (OR 8.1, 95% CI 1.75–37.42, p = 0.008), underlying cardiovascular disease (OR 3.5, 95% CI 1.19–10.47, p = 0.023), ground-glass opacity on chest X-ray (OR 2.6, 95% CI 1.52–4.30, p < 0.001), and oxygen desaturation during the 6-min walk test (OR 1.9, 95% CI 1.20–3.06, p = 0.007). This study highlights that patients recovering from moderate-to-critical COVID-19 often exhibit abnormal spirometry, notably a restrictive pattern and PRISm. Routine spirometry screening for high-risk patients is recommended.

The role of peer support in recovery among clients with mental illness attending the psychiatric service in a tertiary hospital in Malaysia: a qualitative study

BackgroundThe understanding that mental health recovery is a personal and subjective experience informs mental health policies in many countries. However, most of the populations in these studies are from the West, limiting their applicability in Asia. Peer support in mental health refers to helping and mentoring people who have overcome similar obstacles. Despite being proven to be effective in promoting recovery, little is known about its use in Malaysian psychiatric patients. This study aims to explore the participants’ perspectives on their concept of recovery and how the peer support group (PSG) aid them to achieve recovery.MethodologyThis study was conducted on clients with mental illness who attended the PSG provided by the Community Psychiatry and Psychosocial Intervention Unit in National University Malaysia Medical Centre. A qualitative generic inductive approach was employed in this thematic exploratory study. Purposive sampling was the method used to collect the data for this thematic exploratory study. In-depth interviews of 11 study participants were audio recorded and transcribed verbatim. Data were analyzed using Braun and Clarke (2006) descriptive thematic analysis method.ResultsThe findings of this study highlighted six key themes; three pertaining to the participants’ perspectives on the meaning of recovery (1. Gaining self-reliance and social inclusion, 2. Personal growth and improved life circumstances in recovery, and 3. Symptoms improvement) and another three pertaining to how the peer support group aids recovery (1. Empowerment and growth through peer support, 2. Promoting well-being, 3. Social connection and support).ConclusionThe findings of this study provide valuable insights into the perspectives of psychiatry clinic patients enrolled in PSG on the concept of recovery and the role of such groups in their recovery journey. The findings demonstrated that the PSG complemented the participants’ perspectives on recovery, reinforcing the notion that a comprehensive and person-centered approach to mental health services is essential for successful and sustained recovery outcomes.

Differential metabolomic pathway analysis in Malaysian childhood acute lymphoblastic leukemia patients treated with high-dose methotrexate

BackgroundMethotrexate (MTX) is the mainstay of the consolidation and maintenance phase of chemotherapy protocol for childhood acute lymphoblastic leukemia (ALL). This study aimed to investigate the altered metabolism associated with high dose-MTX and determine the potential of the metabolic markers and differential pathways involved in MTX therapy. MethodsSerum samples were collected from 38 children with ALL at 2 time points: p-MTX; before induction chemotherapy was initiated, and post-MTX; after completion of the first high-dose MTX. The samples were analyzed using HPLC/MS-QTOF. Data acquisition was performed using Agilent MassHunterTMB.05.00 software for subsequent metabolomics analysis. Differential expressions of metabolites were analyzed using univariate Welch's t-test unequal variance. Compounds were identified using the METLIN Database. Pathways and network analyses were performed using Metaboanalyst 4.0. Potential biomarkers were analyzed using the Receiving Operator Characteristic curve. ResultsMetabolites with AUC between 0.7 and 0.9 include xanthine (0.889), oxoglutaric acid (0.770), and alpha-linolenic acid (ALA) (0.741). Alpha-linolenic acid abundance was detected in ALL patients with remission status, corresponding to a test sensitivity and specificity of 0.77 and 0.87, respectively. ALA has an antineoplastic effect that potentially inhibits the proliferation of leukemic cells by inhibiting caspase activation in the phosphatidylinositol 3-kinase (PI3K) pathway and Bcl-2 inhibition. ConclusionIn this study, ALA was found to be significantly higher in patients treated with high-dose MTX and associated with remission status than in pre-MTX treatment.

Study on intestinal parasitic infections and gut microbiota in cancer patients at a tertiary teaching hospital in Malaysia

Intestinal parasitic infections (IPIs) can lead to significant morbidity and mortality in cancer patients. While they are unlikely to cause severe disease and are self-limiting in healthy individuals, cancer patients are especially susceptible to opportunistic parasitic infections. The gut microbiota plays a crucial role in various aspects of health, including immune regulation and metabolic processes. Parasites occupy the same environment as bacteria in the gut. Recent research suggests intestinal parasites can disrupt the normal balance of the gut microbiota. However, there is limited understanding of this co-infection dynamic among cancer patients in Malaysia. A study was conducted to determine the prevalence and relationship between intestinal parasites and gut microbiota composition in cancer patients. Stool samples from 134 cancer patients undergoing active treatment or newly diagnosed were collected and examined for the presence of intestinal parasites and gut microbiota composition. The study also involved 17 healthy individuals for comparison and control. Sequencing with 16S RNA at the V3–V4 region was used to determine the gut microbial composition between infected and non-infected cancer patients and healthy control subjects. The overall prevalence of IPIs among cancer patients was found to be 32.8%. Microsporidia spp. Accounted for the highest percentage at 20.1%, followed by Entamoeba spp. (3.7%), Cryptosporidium spp. (3.0%), Cyclospora spp. (2.2%), and Ascaris lumbricoides (0.8%). None of the health control subjects tested positive for intestinal parasites. The sequencing data analysis revealed that the gut microbiota diversity and composition were significantly different in cancer patients than in healthy controls (p < 0.001). A significant dissimilarity was observed in the bacterial composition between parasite-infected and non-infected patients based on Bray–Curtis (p = 0.041) and Jaccard (p = 0.021) measurements. Bacteria from the genus Enterococcus were enriched in the parasite-infected groups, while Faecalibacterium prausnitzii reduced compared to non-infected and control groups. Further analysis between different IPIs and non-infected individuals demonstrated a noteworthy variation in Entamoeba-infected (unweighted UniFrac: p = 0.008), Cryptosporidium-infected (Bray–Curtis: p = 0.034) and microsporidia-infected (unweighted: p = 0.026; weighted: p = 0.019; Jaccard: p = 0.031) samples. No significant dissimilarity was observed between Cyclospora-infected groups and non-infected groups. Specifically, patients infected with Cryptosporidium and Entamoeba showed increased obligate anaerobic bacteria. Clostridiales were enriched with Entamoeba infections, whereas those from Coriobacteriales decreased. Bacteroidales and Clostridium were found in higher abundance in the gut microbiota with Cryptosporidium infection, while Bacillales decreased. Additionally, bacteria from the genus Enterococcus were enriched in microsporidia-infected patients. In contrast, bacteria from the Clostridiales order, Faecalibacterium, Parabacteroides, Collinsella, Ruminococcus, and Sporosarcina decreased compared to the non-infected groups. These findings underscore the importance of understanding and managing the interactions between intestinal parasites and gut microbiota for improved outcomes in cancer patients.

The relationship between strong-ties weak-ties rationality and COVID-19 public stigma: A cross-cultural study of Malaysia and Australia.

We investigated the relationship between strong-ties versus weak-ties rationality and public stigma (PS) during the COVID-19 pandemic. We also explored the cultural group differences (Malaysians vs. Australians) in this relationship. An online survey was conducted in 2021 with a final sample of 830 eligible Malaysians and 394 eligible Australians. Participants completed the multidimensional strong-ties weak-ties rationality Scale (STWTRS) and an adapted public stigma (PS) scale towards COVID-19 patients. Through multiple regression analysis, we found that the strong-ties rationality, ST-Authoritarian rationality, was positively associated with PS-Blame in both countries. However, the variable Country moderated the relationship between ST-Communal and PS-Rejection, with a negative association found in Malaysia and a positive association in Australia. The findings confirmed the strong-ties weak-ties rationality framework, where ST rationality, especially ST-Authoritarian, could explain the cognitive mechanism behind negative attitudes towards those who pose threat towards the in-group survival. However, ST-Communal could buffer the rejection towards the COVID-19 patients in Malaysia due to its emphasis on social harmony. This study can inform future interventions aimed at mitigating stigma and promoting a more inclusive and supportive society in times of crisis.

Effect of Olfactory Rehabilitation on the Recovery of Post-Coronavirus Disease Olfactory Dysfunction: A Randomized Controlled Trial.

Introduction Persistent olfactory dysfunction was seen in many patients upon coronavirus disease 2019 (COVID-19) infection recovery. However, research on its management was very limited, especially among the Southeast Asian population. Objectives We aim to investigate the role of olfactory rehabilitation and topical corticosteroids among post-COVID-19 olfactory dysfunction patients in Malaysia, and at the same timeto determine factors leading to olfactory recovery post-COVID-19 infection. Methods Adult Malaysians with persistent olfactory dysfunction one month post-COVID-19 recovery were recruited. Thirty-one patients were randomly assigned into three groups with 10 patients being given olfactory training (Group 1), another 10 being given mometasone furoate nasal spray/olfactory training (Group 2), and 11 patients being assigned to the control group (Group 3). All groups were followed up for an average duration of six months. Olfactory function was evaluated by Top International Biotech Smell Identification Test (TIBSIT) scores and Olfactory Disorder Questionnaire (eODQ) prior to randomization, at three and six months after recruitment. Results The baseline characteristics of patients were similar in all groups. Generally, patients of all three groups showed a statistically significant improvement in the TIBSIT scores after six months. The TIBSIT scores for Group 2 were statistically significantly higher than the control at three months but not at six months. As for Group 1, no statistically significant differences in TIBSIT scores at both three and six months were noted when compared to control. Statistically significant improvements were seen in the eODQ scores in all three groups. Conclusion No superiority of intervention for post-COVID-19 olfactory dysfunction was seen compared to control.
