Introduction: The Healthier Choice Logo (HCL) was introduced in 2017 by the Ministry of Health Malaysia. This paper analysed acceptance of HCL, effectiveness of HCL in encouraging healthier product reformulation, and factors affecting reformulation among food industries. Methods: An online self-administered questionnaire consisting of four sections utilising multiple choice and 5-point Likert scale questions was distributed to food industries in Malaysia. Sample size calculation yielded 100 respondents. Results: Food industries had a higher acceptance of the processes and requirements involved in HCL implementation. HCL was highly effective in encouraging product reformulation among food industries in Malaysia. Meeting consumer demand, improving brand image, public health, more awareness around nutrition labelling, logo and national nutrition target, more technical knowledge and budget were found to motivate healthier product reformulation. However, product suitability, consumer acceptability, difficulties maintaining taste and shelf life, and limited budget were the challenges faced in product reformulation. There was no correlation between HCL acceptance and factors encouraging or inhibiting reformulation. Conclusion: These findings are expected to help relevant authorities or stakeholders make changes, if necessary, towards processes and requirements involved in HCL application to ensure wider HCL implementation. Future research should identify the relationship between HCL implementation and public health improvement among the Malaysian population.

Introduction: Differences in baseline characteristics and response to treatment in different age groups of patients with chronic myeloid leukaemia (CML) in resource-limited countries have not been extensively studied. We aimed to determine the differences in clinicopathological parameters at diagnosis and response to imatinib in adult CML patients with younger (under 60 years; YCML) and older (60 years and older; OCML) age treated at our institution from March 2001 to March 2021. Methods: A retrospective analysis of consecutive adult CML patients receiving imatinib was performed. Clinicopathological parameters and treatment response were reviewed and analysed using hospital medical records and electronic data reports. Results: The median age at diagnosis was 50 years. OCML patients (n=17) had significantly more comorbidities. The YCML group (n=50) generally had a palpable spleen >5cm from the costal margin, mild anaemia, hyperleukocytosis and thrombocytosis. A starting dose of 400 mg/day was observed in 84% of YCML and in 65% of OCML. Cumulative complete cytogenetic response was 50% in YCML versus 70.6% in OCML, p=0.158. OCML tended to have a higher percentage of major molecular response (MMR) (52.9% versus 32%) and a shorter time to MMR, 22 months (range 5-70) versus 35 months (range 8-53). OCML experienced more haematological and non-haematological treatment-related adverse events after imatinib therapy. Conclusion: Although OCML patients had more comorbidities and treatment intolerances, overall long-term treatment response was comparable to YCML. In OCML, a more personalised approach to initial and subsequent dosing of imatinib may be considered.

To study the characteristics of paediatric patients admitted to two non-COVID-19 teaching hospitals before and during the implementation of the Movement Control Order (MCO) in Malaysia. The retrospective study was performed in two phases (before MCO between February to March 2020, and during MCO lockdown between March to April 2020) in two teaching hospitals on the East Coast of Peninsular Malaysia. Hospitalized children <18 years were included and those coming for elective procedures or oncology treatment were excluded. The clinical data were retrieved from both hospitals’ admission records. There was a total of 496 and 191 admissions to two teaching hospitals on the East Coast of Peninsular Malaysia, respectively. A significant reduction in the number of non-COVID-19 hospital admissions was seen in both hospitals. For Hospital Universiti Sains Malaysia, the daily hospital admissions were reduced with a mean of 10 (before MCO) to 7 (during MCO) admissions/day (95% CI 1.54,7.54, p=0.001). In Sultan Ahmad Shah Medical Centre, a reduction in hospital admission was seen from 5 (before MCO) to 3 (during MCO) admissions/day (95% CI 0.61, 3.15, p=0.005). Our study observed a general drop in non-COVID-related respiratory illnesses and infectious disease cases during the MCO period. There were significant differences in neurological (p=0.029) and accident (p = 0.001) cases admissions observed between the two periods. Public health social distancing has indirectly reduced the non-COVID-19 related cases in the hospital settings with an increase in accidental injuries among the children during the MCO period.
COVID-19

Herpes simplex virus remains the commonest organism of sporadic encephalitis. Common presentations in herpes simplex encephalitis are seizures and behavioural changes apart from fever, lethargy and headache. Cardiac manifestations, nonetheless, are uncommon in herpes simplex infection. We presented an 8-year-old boy with clinical meningoencephalitis and bradycardia. The initial impression was typhoid meningitis due to severe bradycardia. He was managed in paediatric intensive care unit with transcutaneous cardiac pacemaker and infusion of low dose noradrenaline until the bradycardia resolved. A diagnosis of herpes simplex encephalitis was made based on clinical and specific right temporal and focal radiological findings including right insular ribbon involvement, focal changes over temporal and frontal electroencephalographic (EEG) inference and positive HSV IgM serological confirmation.

his is a short-term longitudinal study of physical, cognitive, psychological and functional outcomes following mild traumatic brain injury (mTBI) in adults, caused by road traffic accident (RTA). Outcome measures were the Montreal Cognitive Assessment (MoCA), the Neuropsychological Assessment Battery Screening Module (S-NAB), the Patient Health Questionnaire (PHQ-9) and the Generalized Anxiety Disorder 7 (GAD-7) scale. Functional outcomes included returning to working/academia and driving, lifestyle changes, financial claims and litigation status. A total of 285 individuals were diagnosed with mTBI, involving young male motorcyclists (90%): uncomplicated mTBI, n=201; complicated mTBI, n=84. Ethnic distribution consisted of 204 Malays, 58 Indians and 23 Chinese. MoCA detected cognitive deficits (mean=23.11, SD=3.41) within 72 hours of injury. At two weeks, somatic manifestations, physical injuries, cognitive deficits and psychological symptoms were detected. At three months of injury, the language domain was persistently impaired, with a lower score on most cognitive domains in the complicated mTBI category than the uncomplicated mTBI. Psychological and somatic symptoms had improved. Almost 50% of patients had returned to a functional baseline within two weeks of injury and a further 24% within three months. A small proportion of patients made active lifestyle changes (<25%), financial injury claims (38%) and were involved in litigation (11%). In conclusion, mTBI in multi-ethnic Malaysia has multifaceted deficits and outcomes. Early management of symptoms may promote maximum recovery.

Objective: To determine the etiologies of tropical acute febrile illness (TAFI) in West Pahang, Malaysia and to investigate morbidity and mortality factors in relation to TAFI. Methods: A multicenter prospective cohort study was conducted between January and June 2016 in six district hospitals throughout the western part of Pahang State in Peninsular Malaysia. A total of 336 patients answered a standardized questionnaire and blood samples were collected for laboratory confirmation of infectious etiology. Descriptive analysis and logistic regression were performed to identify factors associated with TAFI. Results: A total of 336 patients were included. The patients were mainly Malays (70.2%), males (61.3%), aged (44.6±17.4) years, with more than half (58.9%) presenting with gastrointestinal symptoms. The majority were diagnosed with dengue (35.7%) while malaria (4.5%) was the least frequent. The in-hospital mortality due to TAFI was 9.2%. Patients with meliodosis had five times higher mortality [Adjusted OR: 5.002, 95% CI: (1.233, 20.286)]. Patients with comorbidities such as cardiovascular symptoms (P <0.001) and renal replacement therapy initiation (P <0.001) were significantly associated with in-hospital mortality in all TAFI. Conclusions: The etiology of TAFI in the western Pahang includes dengue, leptospirosis, malaria and melioidosis, which carry the highest risk of in-hospital mortality. The presence of cardiovascular symptoms may be used to assess the disease severity in TAFI, but more studies are needed in the future.

This review aimed to provide a comprehensive overview of ruminant and human fascioliasis in Malaysia and to identify research gaps in knowledge of the prevalence of fascioliasis in Malaysia and risk factors for the disease using available evidence-based data. We conducted a scoping review based on the framework of Arksey and O’Malley. The preferred reporting items for systematic reviews and meta-analyses were used to guide the review process. The citation search was performed between May and September 2018. Using specific keywords, literature published between 1998 to September 2018 was retrieved from electronic databases. Six articles related to fascioliasis in Malaysia were included in the final review from 1,932 screened articles and reports. Five studies focused on ruminants, including cattle, buffaloes, sheep and goats in the states of Terengganu and Perak. The most frequent ruminant fascioliasis outbreaks involved cattle and goats, with a prevalence of 82%–95% and these outbreaks occurred in Terengganu. Only one study examined the risk of fascioliasis in cattle. In the study, the age and sex of the cattle were important risk-related parameters. The search returned only one documented report of a suspected case of human fascioliasis with an atypical clinical presentation. At present, human fascioliasis in Malaysia remains under-reported and its prevalence remains unknown. The data summarised in this review based on existing evidence identifies research gaps on fascioliasis in ruminants and humans.

Introduction: The lubricant thickness in clearance between bearing surfaces for metallic hip implants are currently incapable of accommodating the motion experienced (high load and low entraining motion) in hip walking cycle. Thus, micro-dimpled surfaces were introduced onto surfaces of metallic acetabular cups to improve lubricant thickness. Micro-dimpled surface is a method of advanced surface improvement to increase the lubricant thickness in various tribological applications, such as hip implants. However, the application of micro-dimpled surfaces in hip implants has not yet been explored adequately. Therefore, this study aims to identify the influence of micro-dimpled depth on lubricant thickness elastohydrodynamically for metallic hip implants using Fluid-Structure Interaction (FSI) approach. Methods: Fluid-Structure Interaction (FSI) approach is an alternative method for analysing characteristics of lubrication in hip implant. Dimples of radius 0.25 mm and various depths of 5μm, 45μm and 100μm were applied on the cup surfaces. The vertical load in z-direction and rotation velocity around y-axes representing the average load and flexion-extension (FE) velocity of hip joint in normal walking were applied on Elastohydrodynamic lubrication (EHL) model. Results: The metallic hip implants with micro-dimpled surfaces provided enhanced lubricant thickness, namely by 6%, compared to non-dimpled surfaces. Furthermore, it was suggested that the shallow depth of micro-dimpled surfaces contributed to the enhancement of lubricant thickness. Conclusion: Micro-dimpled surfaces application was effective to improve tribological performances, especially in increasing lubricant thickness for metallic hip implants.

Locked knee is an orthopaedic condition requiring urgent treatment. Although the condition can be diagnosed via history, physical examination and imaging studies, the cause of the mechanical obstruction may only be apparent during arthroscopic examination of the knee joint. It is known that imaging plays a role in evaluating the integrity of intra-articular structures, however in some atypical cases, imaging cannot identify the definitive cause of locked knee. Here we report on two cases of locked knee, due to uncommon conditions which were unobservable via normal imaging studies.

Aims: Bacterial heart rot (BHR) disease caused by Erwinia chrysanthemi or the new nomenclature Dickeya zeae was identified as the lethal disease of pineapple and caused massive losses for the farmers due to non-satisfactory solutions. Thus, this study aims to understand the disease dissemination pattern and screen for tolerance pineapple variety prior to establishment of disease management strategies. Methodology and results: Dissemination of BHR disease was observed visually in 2 study plots consisting 200 plants in each plot. Single plant inoculation of the pathogen was done in each plot namely Plot A at the edge and Plot B at the middle. Disease incidence was recorded at weekly interval for 12 weeks. The pattern of disease spreading in both plots was then mapped based on the results. Separately, 8 commercial pineapple varieties (Maspine, N36, MD2, Morris, Sarawak, Kristal, Gandul and Josapine) were screened for their resistance towards BHR. The varieties screening study was carried out using complete randomized block design. Overall, disease incidence (DI) was observed lower in plot A compared to Plot B. Percentage of DI in Plot A increased continuously from week 1 to 12, but in plot B the DI was stagnant starting from week 3 onwards. This study revealed that there is highly significant difference in percentage of infection between varieties tested. Josapine and MD2 were the most infected varieties based on lesion on plant. Both were found susceptible to BHR. Besides that, Chrystal Honey, Maspine and Sarawak varieties were less infected and classified as moderately resistance compared to other varieties. Conclusion, significance and impact of study Inoculum source was recognized as determinant factor for dissemination of BHR. Aggregation pattern was observed, and disease spreading was severe when disease started from the edge of the plot compared to in the middle. These findings will help farmers to choose the varieties of interest and plan for disease control measure based on first observed disease symptom in their field. This study is also important to researchers and plant breeders for varietal improvement in the future.
