OBJECTIVE: Our study objectives were (a) to investigate the heritability of age of menarche in twins, (b) to obtain the association between age of menarche and childhood factors, and reproductive events/behavior, (c) to examine whether or not having a male co-twin affects early/late menarche.
METHODOLOGY: A group of female-female identical (n = 108, 54 pairs), non-identical twins (n = 68, 34 pairs) and 17 females from opposite-sex twin sets were identified from twin registries of Malaysia and Iran. Genetic analysis was performed via two methods of Falconers' formula and maximum likelihood.
RESULTS: Heritability was found to be 66% using Falconers' formula and 15% using univariate twin analysis. Model analysis revealed that shared environmental factors have a major contribution in determining the age of menarche (82%) followed by non-shared environment (18%).
DISCUSSION: Result of this study is consistent with that of the literature. Timing of menarche could be under the influence of shared and non-shared environmental effects. Hirsutism was found to have a higher frequency among subjects with late menarche. There was no significant difference in age of menarche between females of opposite-sex twins and females of same-sex twins.
CONCLUSION: It is concluded that twin models provide a powerful means of examining the total genetic contribution to age of menarche. Longitudinal studies of twins may clarify the type of environmental effects that determine the age of menarche.
OBJECTIVE: To determine the extent of unlicensed and off-label use of medicines in hospitalised children in the intensive care units of a tertiary care teaching hospital.
METHODS: A prospective, observational exploratory study was conducted on medicines prescribed to children admitted to the 3 intensive care units of Universiti Kebangsaan Malaysia Medical Centre (UKMMC).
RESULTS: A total of 194 patients were admitted to UKMMC, 168 of them received one or more drugs. Of 1,295 prescriptions, 353 (27.3 %) were unlicensed and 442 (34.1 %) were for off-label use. Forty-four percent of patients received at least one medicine for unlicensed use and 82.1 % received at least one medicine off-label. Preterm infants, children aged 28 days to 23 months, patients with hospital stays of more than 2 weeks, and those prescribed increasing numbers of medicines were more likely to receive medicines for unlicensed use. Term neonates and patients prescribed increasing numbers of medicines had increased risk of receiving medicines for off-label use.
CONCLUSION: Prescribing of medicines in an unlicensed or off-label fashion to the children in the intensive care units of UKMMC was common. Further detailed studies are necessary to ensure the delivery of safe and effective medicines to children.
METHOD: This cross-sectional study was conducted on a sample of 256 conveniently selected elderly Malaysians who were residing in the states of Selangor and Kuala Lumpur. A pre-validated interview-administered questionnaire was used to gather information. Data was entered into PASW version 18 and analyzed.
RESULTS: A total of 256 questionnaires were included in the study. A response rate of 64% was achieved. Out of 256 respondents, 92 (35.9%) were male while 164 (64.1%) were female. More than half of the respondents (n = 141; 55.1%) agreed that CAM is more effective than allopathic medicine. Chinese respondents showed strong belief in the effectiveness of CAM. In terms of safety of CAM, close to three quarters of respondents (n = 178; 69.5%) believed that CAM is safer than allopathic medicine. A large majority of respondents agreed that CAM has less side effects compared to allopathic medicine (n = 201; 78.5%) and also agreed that CAM is good to maintain overall health and wellbeing (n = 212; 82.8%). A majority of the respondents expressed that they use CAM because allopathic medicine is less effective (n = 113; 44.1%).
CONCLUSION: The current study reflects the reasons of using CAM among lay public from different ethnicities. There are no reports of adverse effects related to CAM use. Future approaches should be intended for awareness campaigns for consumers, highlighting safety profile of CAM and as well as forbidding their use without the consultation of healthcare professional.
MATERIALS AND METHODS: The serum and peripheral blood gene expression levels of C-reactive protein (CRP) and von Willebrand factor (vWF) in multiethnic Malaysian patients (n = 7) admitted with early hospitalization of ACS was evaluated. Nine patients with stable coronary artery disease without previous history of ACS were enrolled as controls.
RESULTS: Serum and peripheral blood mRNA levels of CRP and vWF were significantly higher in ACS compared to control groups (P
