Haemophilia B is caused by coagulation defects in the factor IX gene located in Xq27.1 on the X chromosome. Identifi cation of mutations contributing to defective factor IX may be advantageous for precise carrier and prenatal diagnosis. We studied 16 patients from 11 families, consisting of 8 patients of the Malay ethnic group, of which 6 were siblings. Factor IX mutations have not been previously reported in the Malay ethnic group. The functional region of the factor IX gene was sequenced and mutations were identifi ed in either the exon or intronic regions in 15 of the patients. One novel mutation, 6660_6664delTTCTT was identifi ed in siblings with moderate form of haemophilia B. Mutations identifi ed in our patients when linked with disease severity were similar to fi ndings in other populations. In summary, this preliminary data will be used to build a Malaysian mutation database which would facilitate genetic counseling.

Hibiscus sabdariffa Linn. (roselle) is a polyphenol rich fruit. This study aimed to identify the neuroprotective effect of roselle on LPS-induced cell proliferation and nitric oxide-induced free radical in microglia and neuroblastoma cells. MTT assay was used to identify the appropriate concentration of roselle and LPS for microglia and neuroblastoma cells proliferation study. Griess assay were used to determine the level of nitric oxide accumulated based on the reaction of Griess to estimate the activity of iNOS in nitric oxide production. The results showed that roselle at the concentration of 50 μg/mL and 100 μg/mL and LPS at concentration of 1 μg/mL does not give cytotoxic effect towards microglia C8-B4 and neuroblastoma LN18 cells. The roselle treatment at 50 μg/mL and 100 μg/mL showed a protective effect on LPS-induced microglia C8-B4 cells. However, in neuroblastoma LN18 cells, no protective effect was seen on both 50 μg/mL and 100 μg/mL of roselle treatment following induction with 1 μg/mL of LPS. On the other hand, the production of nitric oxide (NO) was reduced when LPS-induced microglia C8-B4 cells were treated with 50 μg/mL of roselle. Treatment of roselle at concentration 100 μg/mL on LPS-induced neuroblastoma LN18 cells also reduced the production of nitric oxide. As a conclusion, roselle had the ability to give neuroprotective effect by the inhibition of LPS induction activity on microglia activation for normal and cancer cells at different concentrations.

Aging is associated with increased risk of frailty and malnutrition. However, food insecurity has rarely been highlighted in the elderly population, especially among the low income group. Thus, a cross-sectional study was conducted to determine the association between nutritional status, food insecurity and frailty among elderly in low income residences in Klang Valley. A total of 72 elderly individuals aged 60 years and above was selected (mean age 66 ± 6 years) through convenient sampling. Participants were interviewed to obtain information on socio-demographic, health status, food insecurity and cognitive status. Anthropometrics parameters and frailty assessments was measured using standard criteria. Results showed that 75.0% of the participants had abdominal obesity. Nearly half of the participants were overweight (41.7%), followed by normal (43.0%) and underweight (15.3%). With respect to food insecurity, most of them reported that they had enough food (93.1%). There were significant correlation (p < 0.05) between food insecurity with height (r = -0.263, p = 0.026). Most of the participants were pre-frail (58.3%), frail (27.8%) and followed by non-frail (13.9%). Calcium intake is inversely associated with frailty (t = -2.62, p = 0.011). In conclusion, food insecurity was not a problem, however, half of the subjects were overweight and pre-frail. Three out four subjects had abdominal obesity. There is a need to investigate further the pathogenesis of fat frail in this low income elderly population and formulate effective intervention strategies.

Background & Objectives: The burden of stroke is increasing, in part due to increasing prevalence of diabetes mellitus. Given the high prevalence of diabetes in the Malaysian population (22.6%), we aimed to determine the prevalence of diabetes in our stroke population. We also aimed to study the stroke subtype associated with diabetes. We hypothesized that lacunar infarction would be more prevalent in diabetics. Methods: We retrospectively reviewed data of consecutive patients with acute ischaemic stroke admitted from October 2004 to December 2010 from our stroke registry. Demographic data, risk factors profile and stroke subtypes were reviewed and analyzed. Results: Eight hundred and fifty eight patients were identified from the registry. As high as 59.3% (n=509) of our patients were diabetics, of which 49.2% (n=422) had pre-existing diabetes and 10.1% (n=87) were newly diagnosed. Lacunar infarction was the commonest stroke subtype, comprising 60.6% (n=519) of all strokes. Diabetes was significantly associated with lacunar infarction (OR 1.5, CI 95% 1.16-2.01, p=0.003), particularly in those aged ≤ 55 years (OR 2.29, 95% CI 1.12-4.67) and HbA1C ≥ 6.5% (χ²=8.77, p=0.003). Conclusions: The prevalence of diabetes in our stroke patients is amongst the highest reported. Diabetes mellitus, particularly those with poor glycaemic control is strongly associated with lacunar infarction.

A phytochemical study of Alphonsea cylindrica King (unreported) has led to the isolation of six alkaloids. The compounds were identified as kinabaline (1; azafluorenone alkaloid), muniranine (2), O-methylmoschatoline (3; oxoaporphine alkaloid), lysicamine (4), atherospermidine (5) and N-methylouregidione (6; 4, 5-dioxoaporphine alkaloid). The structures of the isolated compounds were determined based on the spectroscopic techniques and by comparison with data reported in the literature. Alkaloid 2 was isolated as a new derivative of azafluorenone while alkaloids 1, 3 - 6 were isolated for the first time from Alphonsea species. In addition, alkaloid 3 and 4 showed inhibition zone against Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus cereus in disc diffusion test. The minimum inhibition concentration (MIC) values of lysicamine (4) against S. aureus, B. cereus and P. aeruginosa were found to be smaller than O-methylmoschatoline (3). Therefore, the reported antibacterial activity showed the potential of this plant as natural antibacterial agent and supported the documented traditional use of Alphonsea sp. in the treatment of diarrhea and fever.

Introduction: School students are young adolescents who are in a period of acquiring good oral hygiene habits that are practised as they grow up. This study aimed to determine the association between oral health knowledge, attitude and practices (KAP) of the adolescents and their dental plaque maturity status. Methods: A cross-sectional study was conducted among 174 school students aged 13 to 14 years in Kota Bharu, Kelantan. The oral health knowledge, attitude and practices were assessed by self-administered questionnaires, while the dental plaque maturity status was assessed using GC Tri Plaque ID gel TM (TPID). The data were analysed using IBM SPSS version 24.0. Results: The mean (SD) for knowledge and attitude score of the students were 4.69 (1.44) and 3.63 (0.63), respectively. The mean (SD) dental plaque maturity score (DPMS) of the students was 1.02 (0.55). Students who had answered correctly on sugar and practised tooth brushing twice daily had significantly lower mean DPMS as compared to those who had answered incorrectly and practised tooth brushing less than twice daily (p<0.05). Conclusion: Adolescents participated in this study had moderate oral health knowledge and good oral health attitude. Correct knowledge regarding sugar and toothbrushing routines of at least twice a day significantly associated with the dental plaque maturity status.

Introduction: Undergraduate students are at a high risk for food insecurity and knowledge on relevant coping strategies is the key issue in dealing with food insecurity. Therefore, this study is aimed at determining the food insecurity status, coping strategies, and the factors associated with food insecurity and coping strategies during the COVID-19 pandemic. Methods: This cross-sectional study involved 383 undergraduate students from health-related courses at the International Islamic University Malaysia Kuantan campus. The participants were selected by convenience sampling. The instrument used for data collection was a self-administered questionnaire consisting of three parts: socio-demographic background, food insecurity, and coping strategies. The data were analysed as descriptive and inferential analyses, such as Chi-Square, Mann-Whitney, and Kruskal-Wallis. Results: It was found that 21.41% of the participants reported experiencing food insecurity. There were significant associations between parents’ income (p<0.001), financial status (p<0.001), academic performance (p = 0.04) and working part-time (p = 0.01) with food insecurity. It was also discovered that there were significant associations between working part-time (p<0.001), faculty of study (p<0.001), academic year (p<0.001), financial status (p<0.001), academic cumulative grade point average (CGPA) (p<0.001) and monthly expenses (p = 0.01) with Malaysian Coping Strategies Instruments (MCSI) score. A significant association between food insecurity and MCSI score (p<0.001) was also found in this study. Conclusion: The prevalence of food insecurity was consistent with previous studies, which is considered high in Malaysia. The findings could assist university authorities to identify the characteristics of the students that are related to food insecurity.

Presently, there is no specific federal legislation governing articular cartilage tissue engineering (ACTE) experimentation practices in Malaysia. However, there are related regulations and guidelines provided by government agencies to oversee and guide such practices. The rules and regulations provided in the documents have the essential aim of safeguarding public health through ensuring that non-clinical studies reach a certain quality, efficient and safe for human use. There are themes identified when scrutinising relevant documents which includes, the need for authorised personnel and the establishment of facilities in conducting such experiments, the aspect of cell-scaffold construct development, the use of human materials, the aspect of biosafety, animal care and use during the experiments, and considerations on the impact on the environment. The individual laboratory or facility shall adopt and adapt these standards as deemed appropriate by the ACTE researchers to ensure that non-clinical studies are conducted in a proper and ethical manner.

This study examines, classifies and discusses the ethical issues of tissue engineering published in selected online databases from the year 2015 to 2020. In overview, the published literature could be classified according to the type of ethical issues discussed, the phase in development in which the ethical issues are prominently existing and into the type of journal they are published. It proceeds with in-depth discussions on selected relevant issues that deemed to be needing further attention and clarification. It will give the readers a broad mapping of ethical issues currently existing and discussed in the context of tissue engineering and highlights the conventional responses on the issues.
