The glycosylated haemoglobin (HbA1c) test is the most widely accepted laboratory test for evaluating
long term glycaemic control. Patient’s understanding of HbA1c can lead to better glycaemic control.
This study is aimed to determine the awareness and level of understanding of HbA1c among type 2 DM
patients and its association with glycaemic control. A cross-sectional descriptive study among Type 2
DM patients undergoing routine follow up in an endocrine clinic of a tertiary centre in Malaysia. Patients
were invited to answer a validated questionnaire which assessed their awareness and understanding of
HbA1c. Their last HbA1c results were retrieved from the laboratory information system. A total of
92 participants were recruited. Fifty-six (60.9%) were aware of the term HbA1c. Fifty percent were
categorised as having good HbA1c understanding, with age, monthly income and level of education
being the factors associated with understanding. No significant association was noted between HbA1c
understanding and glycaemic control, although more patients with good HbA1c understanding had
achieved the target glycaemic control compared to those with poor understanding. The level of HbA1c
awareness and understanding was acceptable. Factors associated with understanding were age, income
and level of education. Continuing efforts however, must be made to improve patients understanding of
their disease and clinical disease biomarkers.

This is a questionnaire survey of dietary
supplement usage among students in the International
Medical University. Just over two-fifths of these
students reported using dietary supplements daily. This
high usage of dietary supplements is in contrast their
expressed ambivalence about these products.

INTRODUCTIONThe aims of this article were to review the role of surgical resection in the management of high-grade gliomas and to determine whether there is any survival benefit from surgical resection.
METHODSA literature review of the influence of surgical resection on outcome was carried out. Relevant original and review papers were obtained through a PubMed search using the following keywords: glioma, resection, prognosis and outcome.
RESULTSPresently, there is a lack of evidence to support a survival benefit with aggressive glioma resection, but this should not detract patients from undergoing surgery as there are many other clinical benefits of glioma excision. In addition, limiting surgical morbidity through the use of adjuvant techniques such as intraoperative magnetic resonance imaging (MRI), functional MRI and awake craniotomy is becoming increasingly important.
CONCLUSIONSIdeally, a randomised controlled trial would be the best way to resolve the issue of whether (and to what extent) surgical resection leads to improvements in patient outcome and survival, but this would not be ethical. The second best option would be well-controlled retrospective studies with a multivariate analysis of all potential confounding factors.

Objective:
Patients with severe symptomatic aortic stenosis are assessed for coronary artery disease (CAD) prior to transcatheter aortic valve implantation (TAVI) with treatment implications. Invasive coronary angiography (ICA) is the recommended modality but is associated with peri-procedural complications. Integrating machine learning (ML)-based computed tomography-derived fractional flow reserve (CT-FFR) into existing TAVI-planning CT protocol may aid exclusion of significant CAD and thus avoiding ICA in selected patients.
Materials and Methods:
A single-center, retrospective study was conducted, 41 TAVI candidates with both TAVI-planning CT and ICA performed were analyzed. CT datasets were evaluated by a ML-based CT-FFR software. Beta-blocker and nitroglycerin were not administered in these patients. The primary outcome was to identify significant CAD. The diagnostic performance of CT-FFR was compared against ICA.
Results:
On per-patient level, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy were 89%, 94%, 80%, 97% and 93%, respectively. On per-vessel level, the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 75%, 94%, 67%, 96% and 92%, respectively. The area under the receiver operative characteristics curve per individual coronary vessels yielded overall 0.90 (95% confidence interval 85%–95%). ICA may be avoided in up to 80% of patients if CT-FFR results were negative.
Conclusion
ML-based CT-FFR can provide accurate screening capabilities for significant CAD thus avoiding ICA. Its integration to existing TAVI-planning CT is feasible with the potential of improving the safety and efficiency of pre-TAVI CAD assessment.
