Objective:
The study aims to determine the prevalence and risk factors for endocrine disorders in childhood brain tumour survivors.
Methodology:
124 childhood brain tumour survivors aged 18 years old or younger with either stable disease or in remission, and had survived for at least 2 years after diagnosis were included in the study. Demographic data (age at diagnosis, gender, ethnicity, socioeconomic status), clinical clues for endocrine disorders, anthropometrics (weight, height, midparental height), pubertal staging, tumour-related characteristics, treatment modalities and endocrine laboratory measurements at diagnosis and during follow up were obtained. Logistic regression was applied to evaluate risk factors for endocrine disorders in childhood brain tumour survivors.
Results:
The prevalence of endocrine disorders in childhood brain tumour survivors was 62.1%. The risk factors were high BMI [adjusted odds ratio (OR) 1.29, 95% CI: 1.12 to 1.5], high-risk site [adjusted odds ratio (OR) 7.15, 95% CI: 1.41 to 36.3] and chemotherapy [adjusted odds ratio (OR) 0.18 , 95% CI: 0.05 to 0.62].
Conclusion
The prevalence of endocrine disorders in childhood brain tumour survivors in our centre was 62.1%. The significant risk factors were high BMI, tumour location (suprasellar and intrasellar) and chemotherapy.

Journal of Stroke 2022;24(2):256-265
Background:
and Purpose Recent studies suggested an increased incidence of cerebral venous thrombosis (CVT) during the coronavirus disease 2019 (COVID-19) pandemic. We evaluated the volume of CVT hospitalization and in-hospital mortality during the 1st year of the COVID-19 pandemic compared to the preceding year.
Methods:
We conducted a cross-sectional retrospective study of 171 stroke centers from 49 countries. We recorded COVID-19 admission volumes, CVT hospitalization, and CVT in-hospital mortality from January 1, 2019, to May 31, 2021. CVT diagnoses were identified by International Classification of Disease-10 (ICD-10) codes or stroke databases. We additionally sought to compare the same metrics in the first 5 months of 2021 compared to the corresponding months in 2019 and 2020 (ClinicalTrials.gov Identifier: NCT04934020).
Results:
There were 2,313 CVT admissions across the 1-year pre-pandemic (2019) and pandemic year (2020); no differences in CVT volume or CVT mortality were observed. During the first 5 months of 2021, there was an increase in CVT volumes compared to 2019 (27.5%; 95% confidence interval [CI], 24.2 to 32.0; P<0.0001) and 2020 (41.4%; 95% CI, 37.0 to 46.0; P<0.0001). A COVID-19 diagnosis was present in 7.6% (132/1,738) of CVT hospitalizations. CVT was present in 0.04% (103/292,080) of COVID-19 hospitalizations. During the first pandemic year, CVT mortality was higher in patients who were COVID positive compared to COVID negative patients (8/53 [15.0%] vs. 41/910 [4.5%], P=0.004). There was an increase in CVT mortality during the first 5 months of pandemic years 2020 and 2021 compared to the first 5 months of the pre-pandemic year 2019 (2019 vs. 2020: 2.26% vs. 4.74%, P=0.05; 2019 vs. 2021: 2.26% vs. 4.99%, P=0.03). In the first 5 months of 2021, there were 26 cases of vaccine-induced immune thrombotic thrombocytopenia (VITT), resulting in six deaths.
Conclusions
During the 1st year of the COVID-19 pandemic, CVT hospitalization volume and CVT in-hospital mortality did not change compared to the prior year. COVID-19 diagnosis was associated with higher CVT in-hospital mortality. During the first 5 months of 2021, there was an increase in CVT hospitalization volume and increase in CVT-related mortality, partially attributable to VITT.

Introduction: The aim of the study is to determine the prevalence of burnout and correlation between burnout score
and stressor domain score and to determine the association between sociodemographic and occupational related
factors with overall burnout among nurses caring for children in Hospital Universiti Sains Malaysia (Hospital USM).
Methods: This was a cross-sectional study using bilingual validated questionnaire; the General Stressor Questionnaire (GSQ) and Copenhagen Burnout Inventory (CBI) conducted among nurses providing medical service for children in Hospital USM particularly in wards and clinics. All 159 eligible nurses were recruited and 157 completed
questionnaires were analysed. Pearson’s correlation analysis was applied to study the correlation while simple logistic regression and multiple logistic regressions were applied to study the association. Results: The prevalence of
burnout among nurses caring for children in Hospital USM was 28.7% (95% CI = 21.6, 35.7) with the majority of
them experienced personal burnout (49.7%, 95% CI = 41.9, 57.5). There was a significant moderate positive correlation between different stressor domain score with overall burnout score with p-value < 0.05. Work placement
and bureaucratic constraints were identified as the main contributory factor leading to overall burnout. Conclusion:
Burnout among nurses providing medical services for children in Hospital USM is of concern especially involving
personal burnout. The main stressor related factors of burnout were work placement and bureaucratic constraints.
Therefore, burnout among nurses providing care for children must be addressed in order to enhance their psychological well-being.

ABSTRACT
Kimura disease (KD) is a rare chronic inflammatory disorder of unknown aetiology that primarily affects
the head and neck region with lymph node involvement. Young to middle-aged adult Asian males are
predominantly affected. The most common presentation is painless subcutaneous swelling in the head
and neck region, while proptosis or orbital involvement is very rarely reported. KD shares some features
with other inflammatory and neoplastic disorders, including lymphoma; thus, investigations to confirm
the diagnosis should not be delayed. Systemic corticosteroids are commonly used to treat KD and show
an excellent response; however, the optimal treatment is still uncertain, and KD has a high recurrence
rate. We describe the case of a patient with KD who presented with proptosis and post-auricular
swelling, which responded well to oral prednisolone treatment.

Introduction: This study aimed to determine the views and practices of healthcare providers and
barriers they encountered when implementing the national health screening program for men in a
public primary care setting in Malaysia.
Methods: An online survey was conducted among healthcare providers across public health clinics in
Malaysia. All family medicine specialists, medical officers, nurses and assistant medical officers involved in the screening program for adult men were invited to answer a 51-item questionnaire via email or WhatsApp. The questionnaire comprised five sections: participants’ socio-demographic information, current screening practices, barriers and facilitators to using the screening tool, and views on the content and format of the screening tool.
Results: A total of 231 healthcare providers from 129 health clinics participated in this survey.
Among them, 37.44% perceived the implementation of the screening program as a “top-down
decision.” Although 37.44% found the screening tool for adult men “useful,” some felt that it was
“time consuming” to fill out (38.2%) and “lengthy” (28.3%). In addition, ‘adult men refuse to answer’
(24.1%) was cited as the most common patient-related barrier.
Conclusions: This study provided useful insights into the challenges encountered by the public
healthcare providers when implementing a national screening program for men. The screening tool for
adult men should be revised to make it more user-friendly. Further studies should explore the reasons
why men were reluctant to participate in health screenings, thus enhancing the implementation of
screening programs in primary care.

Objective: To determine the morphological and molecular characterization of Acanthamoeba isolates from contact lens paraphernalia in Malaysia and to investigate their pathogenic potential based on the physiological tolerance. Methods: One hundred and eighty contact lens wearers donated their contact lens, lens storage cases and lens solutions between 2018 and 2019. The samples were inoculated onto 1.5% non-nutrient agar plates for 14 d. Polymerase chain reaction (PCR) was performed and the amplified PCR products were sequenced and compared with the published sequences in GenBank. The pathogenic potential of positive isolates was further tested using temperature-tolerance and osmo-tolerance assays. Acanthamoeba species were categorized into three distinct morphological groups established by Pussard and Pons. Results: Acanthamoeba was successfully isolated from 14 (7.8%) culture-positive samples in which 11 belong to morphological group II and 3 belong to morphological group III, respectively. The sequencing of 18S ribosomal RNA gene led to the identification of the T4 genotype in all the isolated strains. In vitro assays revealed that 9 (64.3%) Acanthamoeba isolates were able to grow at 42 °C and 1 M mannitol and were thus considered to be highly pathogenic. Conclusions: To the best of our knowledge, this is the first report identifying the Acanthamoeba genotype and their pathogenic potential among contact lens wearers in Malaysia. The potentially pathogenic T4 genotype isolated in this study is the most predominant genotype responsible for human ocular infection worldwide. Hence, increasing attention should be aimed at the prevention of contamination by Acanthamoeba and the disinfection of contact lens paraphernalia.

Introduction: The number of breast cancer survivors in developing Asian countries is still lacking compared to
Western countries. Health-related quality of life (HRQoL) of cancer patients is one of the significant predictors of
survival. Hence, this study was conducted to determine HRQoL status among breast cancer survivors of different
diagnosis duration in East Coast of Peninsular Malaysia. Methods: Cross-sectional data were collected for 128 breast
cancer survivors, aged 37 to 72 years who were recruited by using purposive sampling method at two main government hospitals in Kelantan (n=67) and Terengganu (n=61). The validated European Organization for Research and
Treatment of Cancer Quality of Life Questionnaires (EORTC QLQ–C30) and Breast Cancer Supplementary Measure
(EORTC QLQ-BR23) which had been translated into the Malay language were used to measure HRQoL. Independent t-test was used to compare HRQoL status among short term (≤5 years duration since diagnosis) and long term
(>5 years duration since diagnosis) breast cancer survivors. Results: Overall, our breast cancer survivors reported
good HRQoL, with high scores for global health status, functional status and low symptoms scores. Long term breast
cancer survivors had better social functioning compared to short term survivors (p=.038). Nevertheless, there was no
significant difference found for other HRQoL status between short and long term breast cancer survivors. Conclusion:
Breast cancer survivors in East Coast of Peninsular Malaysia generally experienced good HRQoL. The relatively similar HRQoL status between long-term and short-term survivors indicated a constant HRQoL profile among survivors
throughout their survivorship.

OBJECTIVEThis study investigated the effects of allylpyrocatechol (APC), the major component in ethanolic extract of Piper betle, on key oxidative stress resistance enzymes important for the survival of Staphylococcus aureus, a major pathogen in the human host.
METHODSEffects of APC on expressions of genes encoding catalase (katA), superoxide dismutases (SODs), including sodA and sodM, and alkyl hydroperoxide reductase (ahpC) in Saureus were quantitated by RT-qPCR in reference to gyrA and 16S rRNA. Corresponding activities of the enzymes were also investigated. The Livak analysis was performed for verification of gene-fold expression data. Effects of APC on intracellular and extracellular reactive oxygen species (ROS) levels were determined using the nitroblue tetrazolium (NBT) reduction assay.
RESULTSAPC-treated Saureus cells had higher sodA and sodM transcripts at 1.5-fold and 0.7-fold expressions respectively with corresponding increase in total SOD activity of 12.24 U/mL compared to untreated cells, 10.85 U/mL (P<0.05). Expression of ahpC was highest in APC-treated cells with 5.5-fold increased expression compared to untreated cells (P<0.05). Correspondingly, ahpC activity was higher in APC-treated cells at 0.672 (A) compared to untreated cells which was 0.394 (A). In contrast, katA expression was 1.48-fold and 0.33-fold lower respectively relative to gyrA and 16S rRNA. Further, APC-treated cells showed decreased catalase activity of 1.8 ×10(U/L or μmol/(min·L)) compared to untreated cells, which was 4.8 ×10U/L (P<0.05). Absorbance readings (A) for the NBT reduction assay were 0.709 and 0.695 respectively for untreated and treated cells, which indicated the presence of ROS. APC-treated Saureus cells had lower ROS levels both extracellularly and intracellularly, but larger amounts remained intracellularly compared to extracellular levels with absorbances of 0.457 and 0.137 respectively (P<0.05).
CONCLUSIONAPC induced expressions of both sodA and sodM, resulting in increased total SOD activity in Saureus. Higher sodA expression indicated stress induced intracellularly involving O, presumably leading to higher intracellular pools of HO. A concommittant decrease in katA expression and catalase activity possibly induced ahpC expression, which was increased the highest in APC-treated cells. Our findings suggest that in the absence of catalase, cells are propelled to seek an alternate pathway involving ahpC to reduce stress invoked by Oand HO. Although APC reduced levels of ROS, significant amounts eluded its antioxidative action and remained intracellularly, which adds to oxidative stress in treated cells.

OBJECTIVES: Some hospitals have implemented computerized physician order entry (CPOE) systems to reduce the medical error rates. However, research in this area has been very limited, especially regarding the impact of CPOE use on the reduction of prescribing errors. Moreover, the past studies have dealt with the overall impact of CPOE on the reduction of broadly termed "medical errors", and they have not specified which medical errors have been reduced by CPOE. Furthermore, the majority of the past research in this field has been either qualitative or has not used robust empirical techniques. This research examined the impacts of usability of CPOE systems on the reduction of doctors' prescribing errors. METHODS: One hundred and sixty-six questionnaires were used for quantitative data analyses. Since the data was not normally distributed, partial least square path modelling-as the second generation of multivariate data analyses-was applied to analyze data. RESULTS: It was found that the ease of use of the system and information quality can significantly reduce prescribing errors. Moreover, the user interface consistency and system error prevention have a significant positive impact on the perceived ease of use. More than 50% of the respondents believed that CPOE reduces the likelihood of drug allergy, drug interaction, and drug dosing errors thus improving patient safety. CONCLUSIONS: Prescribing errors in terms of drug allergy, drug interaction, and drug dosing errors are reduced if the CPOE is not error-prone and easy to use, if the user interface is consistent, and if it provides quality information to doctors.
