ABSTRACT
INTRODUCTION: Risk factors for cardiovascular disease (CVD) have been increasingly implicated in the development of dementia but little is known about the effects in a Malaysian population. We aimed to determine the interaction between sociodemographic and CVD risk factors among the dementia and mild cognitive impairment (MCI) patients in Malaysia. MATERIALS AND METHODS: A cross-sectional study was conducted in the memory clinic at Hospital Kuala Lumpur (HKL). Medical records data from 2014 to 2019 were extracted. Mini Mental State Examination (MMSE) test was used to assess the neurocognitive function of patients. RESULTS: A total of 298 patients (30 MCI, and 268 dementia) were evaluated, with dementia patients consisting of 78 Alzheimer's disease (AD), 93 Vascular dementia (VaD), 94 Mixed dementia, 2 early-onset Alzheimer's disease (EOAD) and 1 Logopenic Progressive Aphasia type of AD (LPA). MCI and dementia were significantly associated with a history of CVD, particularly stroke (p=0.023). CONCLUSION: Given that stroke significantly predicted the risk of developing vascular dementia among the patients in a central Malaysian population, lifestyle modifications are recommended to alleviate these risk factors of CVD.

We report a rare case of homozygous familial hypercholesterolemia (HoFH), a 22-year-old Malay woman who presented initially with minor soft tissue injury due to a cycling accident. She was then incidentally found to have severe xanthelasma and hypercholesterolemia (serum TC 15.3 mmol/L and LDL-C 13.9 mmol/L). She was referred to the Specialized Lipid Clinic and was diagnosed with familial hypercholesterolemia (FH) based on the Simon Broome (SB) diagnostic criteria. There was a family history of premature coronary heart disease (CHD) in that three siblings had sudden cardiac death, and of consanguineous marriage in that her parents are cousins. DNA screening of LDLR and APOB genes was done by Polymerase Chain Reaction (PCR), followed by Denaturing High Performance Liquid Chromatography (DHPLC). Homozygous mutation C255S in Exon 5 of her LDLR gene was found. There was no mutation was found in Exon 26 and Exon 29 of the APOB gene. This report is to emphasize the importance of identifying patients with FH and cascade screening through established diagnostic criteria and genetic studies in order to ensure early detection and early treatment intervention to minimize the risk of developing CHD and related complications.

Zinc oxide nanoparticles (ZnO-NPs) were synthesized via a solvothermal method in triethanolamine (TEA) media. TEA was utilized as a polymer agent to terminate the growth of ZnO-NPs. The ZnO-NPs were characterized by a number of techniques, including X-ray diffraction analysis, transition electron microscopy, and field emission electron microscopy. The ZnO-NPs prepared by the solvothermal process at 150°C for 18 hours exhibited a hexagonal (wurtzite) structure, with a crystalline size of 33 ± 2 nm, and particle size of 48 ± 7 nm. The results confirm that TEA is a suitable polymer agent to prepare homogenous ZnO-NPs.
