A 24-year-old Chinese woman with Graves' disease presented with myositis two months after treatment with carbimazole. The patient's myositis resolved with hydration and cessation of carbimazole. No other causes of myositis were found, and a change in the medication to propylthiouracil was uneventful. Review of the literature suggests a possible genetic susceptibility, as the majority of reported cases are Asian in origin, similar to patients who present with thyroid periodic paralysis. Changing the antithyroid drugs (ATDs) administered, decreasing the dose of pre-existing ATDs in the treatment regimen or addition of levothyroxine has been shown to result in clinical improvement of this complication. These observations suggest various mechanisms of carbimazole-induced myositis in the treatment of Graves' disease, including the direct effect of ATDs on myocytes, immune-related responses secondary to ATDs and rapid decrements in thyroid hormone with ensuing myositis.

Introduction: In most Asian countries, stroke is one of themajor causes of mortality. A stroke event is life-changing forstroke survivors, which results in either mortality ordisability. Therefore, this study comprehensively focuses onprevalence, risk factors, and secondary prevention forstroke recurrence identified in South, East, and SoutheastAsian countries. Methods: This scoping review uses themethodological framework of Arksey and O’Malley. Acomprehensive search of academic journals (English) onthis topic published from 2007 to 2017 was conducted. Atotal of 22 studies were selected from 585 studies screenedfrom the electronic databases.Results: First-year stroke recurrence rates are in the rangeof 2.2% to 25.4%. Besides that, modifiable risk factors aresignificantly associated with pathophysiological factors(hypertension, ankle-brachial pressure index, atherogenicdyslipidaemia, diabetes mellitus, metabolic syndrome, andatrial fibrillation) and lifestyle factors (obesity, smoking,physical inactivity, and high salt intake). Furthermore, age,previous history of cerebrovascular events, and strokesubtype are also significant influence risk factors forrecurrence. A strategic secondary prevention method forrecurrent stroke is health education along with managingrisk factors through a combination of appropriate lifestyleintervention and pharmacological therapy.Conclusion: To prevent recurrent stroke, health interventionshould be geared towards changing lifestyle to embody ahealthier approach to life. This is of great importance topublic health and stroke survivors’ quality of life.

PURPOSE: Many studies supported that vegetarians have a lower risk of cardiac diseases and mortality, partly due to better blood pressure and serum cholesterol profiles. However, the inflammatory markers, especially lipoprotein-associated phospholipase A2 (Lp-PLA2), have not been well-studied. This study aimed to compare inflammatory markers and conventional risk factors between vegetarians and omnivores. MATERIALS AND METHODS: One hundred and seventy-three vegetarians and 190 omnivores were studied. Fasting blood samples were obtained to compare levels of glucose, total cholesterol, triacylglycerol, high density lipoprotein (HDL) and low density lipoprotein (LDL) cholesterol, homocysteine, Lp-PLA2 activity, and high-sensitivity C-reactive protein (hs-CRP). RESULTS: Vegetarians had higher serum levels of the following markers: hs-CRP (1.8 +/- 3.4 vs. 1.2 1.8 mg/L, respectively; p = 0.05), homocysteine (9.39 +/- 3.22 vs. 7.62 +/- 2.41 micromol/L, respectively; p < 0.01), and triacylglycerol (96.91 +/- 59.56 vs. 84.66 +/- 43.24 mg/dL, respectively; p < 0.05). Vegetarians also had lower levels of Lp-PLA2 (18.32 +/- 7.19 10-3 micromol/min/mL vs. 20.22 8.13 10-3 micromol/min/mL; p < 0.05), total cholesterol (180.62 +/- 36.55 mg/dL vs. 192.73 +/- 36.57 mg/dL; p < 0.01), LDL cholesterol (118.15 +/- 32.8 vs. 126.41 +/- 34.28 mg/dL; p < 0.05), and HDL cholesterol (55.59 +/- 13.30 vs. 62.09 +/- 14.52 mg/dL, p < 0.01). Multivariate analyses demonstrated that a vegetarian diet increases the chances for high serum hs-CRP and low Lp-PLA2 activity. CONCLUSION: In addition to lower total cholesterol, LDL-cholesterol, and HDL-cholesterol, Taiwanese female vegetarians have lower serum Lp-PLA2 activity but higher levels of hs-CRP, homocysteine, and triacylglyerol. It might be due to geographic differences of vegetarian diets, and further studies are needed.

Introduction: The COVID-19 pandemic is a new emerging situation that has dramatically impacted sleep quality and
body weight status. This study aimed to determine the association between sleep quality and body weight status in
Malaysian adults during the COVID-19 pandemic. Methods: An online cross-sectional study involved 427 Malaysian
adults aged 18 to 59. The convenience sampling method was used. Sleep quality was assessed by Pittsburgh Sleep
Quality Index (PSQI). Self-administered socio-demographic, height, and weight for BMI were obtained. Pearson
correlation test was conducted to measure the association between sleep quality and body weight status using IBM
SPSS Statistics for Windows version 22.0. Results: A total of 78.5% of them were females, and 84.8% of Malaysian
adults reported poor sleep quality. The participants’ mean global PSQI score and body mass index were 8.1 (±2.7)
and 24.6 (±6.1) kg/m2, respectively. 8.0% were underweight, followed by 55.5% of normal BMI, 17.5% overweight,
and 19.0% obese. The study showed a significant and positive correlation between global PSQI score and body mass
index (r=0.137, p=0.005). Conclusion: Sleep quality is significantly associated with body weight status. Adults with
poorer sleep quality should be targeted when promoting healthy body weight. Future research on the interventions
to improve adults’ sleep quality is essential, particularly during the pandemic.

Malaysian Journal of Medicine and Health Sciences 2021;17(No.4):373-383
A lack of sleep is a modifiable risk factor for poor health, such as the risk of obesity, diabetes, hypertension, and
metabolic syndrome. This article summarises significant studies that explore the assessment of body weight status
and sleep quality and their association. A literature search was conducted in the electronic databases such as Google
Scholar, PubMed, MEDLINE Complete at EBSCOhost and Scopus. The findings on the association between sleep
quality and body weight status were inconsistent. Both short and long sleep duration were associated with obesity
status. Overall, a positive relationship between sleep and obesity in adults was observed. Further research on sleep
quality and its association with body weight status among adults is needed. Better health is associated with a longer
and sufficient duration of sleep. Therefore, it is of great significance to enhance the public’s awareness of their sleep
quality on body weight status.

BACKGROUND AND PURPOSE: It is essential to develop a reliable predictive serum biomarker for Parkinson's disease (PD). The accumulation of alpha-synuclein (αSyn) and up-regulated expression of Rab35 participate in the etiology of PD. The purpose of this investigation was to determine whether the combined assessment of serum αSyn and Rab35 is a useful predictive biomarker for PD. METHODS: Serum levels of αSyn or Rab35 were determined in serum samples from 59 sporadic PD patients, 19 progressive supranuclear palsy (PSP) patients, 20 multiple system atrophy (MSA) patients, and 60 normal controls (NC). Receiver operating characteristics (ROC) curves were calculated to determine the diagnostic accuracy of αSyn or/and Rab35 in discriminating PD patients from NC or atypical parkinsonian patients. RESULTS: The levels of αSyn and Rab35 were increased in PD patients. The serum level of Rab35 was positively correlated with that of αSyn in PD patients. Compared to analyzing αSyn or Rab35 alone, the combined analysis of αSyn and Rab35 produced a larger area under the ROC curve and performed better in discriminating PD patients from NC, MSA patients, or PSP patients. When age was dichotomized at 55, 60, 65, or 70 years, the combined assessment of αSyn and Rab35 for classifying PD was better in the group below the cutoff age than in the group above the cutoff age. CONCLUSIONS: Combined assessment of serum αSyn and Rab35 is a better biomarker for discriminating PD patients from NC or atypical parkinsonian patients, and is a useful predictive biomarker for younger sporadic PD patients.

INTRODUCTION:
Family history of psychopathology is a risk factor for mood and anxiety disorders in children, but little is known about rates of parental psychopathology among treatment-seeking youth with affective disorders in the Asia Pacific region. This study examined patterns of emotional and behavioural problems in parents of clinically-referred youth in Singapore. We hypothesised that parents would have higher rates of affective disorders compared to the Singapore national prevalence rate of 12%.
MATERIALS AND METHODS:
In this cross-sectional study, 47 families were recruited from affective disorders and community-based psychiatry programmes run by a tertiary child psychiatry clinic. All children had a confirmed primary clinical diagnosis of depression or an anxiety disorder. Parents completed the Mini International Neuropsychiatric Interview (MINI) to assess for lifetime mood and anxiety disorders. They also completed the Adult Self Report (ASR) and Adult Behavior Checklist (ABCL) to assess current internalising and externalising symptoms.
RESULTS:
Consistent with our hypothesis, 38.5% of mothers and 10.5% of fathers reported a lifetime mood and anxiety disorder. Nearly 1/3 of mothers had clinical/subclinical scores on current internalising and externalising problems. A similar pattern was found for internalising problems among fathers, with a slightly lower rate of clinical/subclinical externalising problems.
CONCLUSION
Our findings are consistent with previous overseas studies showing elevated rates of affective disorders among parents - particularly mothers - of children seeking outpatient psychiatric care. Routine screening in this population may help to close the current treatment gap for adults with mood and anxiety disorders.

Purpose:
The aim of this study was to investigate the efficacy of various epidermal growth factor receptor (EGFR)–tyrosine kinase inhibitors (TKIs) plus bevacizumab in advanced EGFR-mutant lung adenocarcinoma patients.
Materials and Methods:
From August 2016 to October 2020, we enrolled advanced lung adenocarcinoma patients harboring exon 19 deletion or L858R receiving gefitinib, erlotinib and afatinib plus bevacizumab as the first-line treatment for the purposes of analysis.
Results:
A total of 36 patients were included in the final analysis. Three patients received gefitinib, 17 received erlotinib, and 16 received afatinib combined with bevacizumab as the first-line treatment. The objective response rate was 77.8%, and disease control rate was 94.4%. The overall median progression-free survival (PFS) was 16.4 months, while the median PFS was 17.1 months in patients with exon 19 deletion, and 16.2 months in patients with L858R mutation (p=0.311). Regarding the use of different EGFR-TKIs, the median PFS was 17.1 months in the erlotinib group and 21.6 months in the afatinib group (p=0.617). In patients with brain metastasis at baseline, the median PFS was 18.9 months in the erlotinib group and 16.4 months in the afatinib group (p=0.747). Amongst patients harboring exon 19 deletion, the median PFS was 16.2 months in the erlotinib group and not-reached in the afatinib group (p=0.141). In patients with L858R mutation, the median PFS was 18.9 months in the erlotinib group and 16.2 months in the afatinib group (p=0.481).
Conclusion
Our research demonstrates that not only erlotinib combined with bevacizumab, but also afatinib plus bevacizumab as first-line treatment, provides solid clinical efficacy in advanced EGFR-mutant lung adenocarcinoma patients.

INTRODUCTION:
Three doses of SARS-CoV-2 mRNA vaccines have been recommended for cancer patients to reduce the risk of severe disease. Anti-neoplastic treatment, such as chemotherapy, may affect long-term vaccine immunogenicity.
METHOD:
Patients with solid or haematological cancer were recruited from 2 hospitals between July 2021 and March 2022. Humoral response was evaluated using GenScript cPASS surrogate virus neutralisation assays. Clinical outcomes were obtained from medical records and national mandatory-reporting databases.
RESULTS:
A total of 273 patients were recruited, with 40 having haematological malignancies and the rest solid tumours. Among the participants, 204 (74.7%) were receiving active cancer therapy, including 98 (35.9%) undergoing systemic chemotherapy and the rest targeted therapy or immunotherapy. All patients were seronegative at baseline. Seroconversion rates after receiving 1, 2 and 3 doses of SARS-CoV-2 mRNA vaccination were 35.2%, 79.4% and 92.4%, respectively. After 3 doses, patients on active treatment for haematological malignancies had lower antibodies (57.3%±46.2) when compared to patients on immunotherapy (94.1%±9.56, P<0.05) and chemotherapy (92.8%±18.1, P<0.05). SARS-CoV-2 infection was reported in 77 (28.2%) patients, of which 18 were severe. No patient receiving a third dose within 90 days of the second dose experienced severe infection.
CONCLUSION
This study demonstrates the benefit of early administration of the third dose among cancer patients.

Objective:
To assess the public health risk to Singapore posed by the emergence of artemisinin-resistant (ART-R) malaria in the Greater Mekong Subregion (GMS).
Methods:
We assessed the likelihood of importation of drug-resistant malaria into Singapore and the impact on public health of its subsequent secondary spread in Singapore. Literature on the epidemiology and contextual factors associated with ART-R malaria was reviewed. The epidemiology of malaria cases in Singapore was analysed. The vulnerability and receptivity of Singapore were examined, including the connectivity with countries reporting ART-R malaria, as well as the preparedness of Singaporean health authorities. Sources of information include international journals, World Health Organization guidelines, data from the Singapore Ministry of Health and National Public Health Laboratory of the National Centre for Infectious Diseases, and the International Air Transport Association.
Results:
The importation of ART-R malaria into Singapore is possible given the close proximity and significant travel volume between Singapore and the GMS countries reporting artemisinin resistance. Singapore’s vulnerability is further enhanced by the presence of foreign workers from neighbouring endemic countries. Nonetheless, the overall likelihood of such an event is low based on the rarity and decreasing trend of imported malaria incidence.
With the presence of Anopheles vectors in Singapore, imported cases of drug-resistant malaria could cause secondary transmission. Nevertheless, the risk of sustained spread is likely to be mitigated by the comprehensive surveillance and control system in place for both infected vectors and human cases.
Discussion
This risk assessment highlights the need for a continued high degree of vigilance of ART-R malaria locally and globally to minimize the risk and public health impact of drug-resistant malaria in Singapore.
