MATERIALS AND METHODS: This review uses the methodological framework of Arksey and O'Malley. A total of 19 studies were selected from 9456 studies screened from the electronic databases.
RESULTS: Majority of the studies reported no association between saturated fat (SFA) and monounsaturated fat (MUFA) with CHD. Meanwhile, seven out of 12 studies reported inverse association between polyunsaturated fat (PUFA) and risk of CHD whilst 67% of the studies found that trans-fat intake was positively associated with CHD risk.
CONCLUSIONS: This review finds that all the types of dietary fat have different effects on the risk of CHD. Nevertheless, intakes of healthy fat such as MUFA and PUFA in controlled amounts are expected to reduce CHD risk. In addition, the divergence of findings found between studies might be due to the methodological inconsistencies. More robust research is needed to determine the actual dietary determinants of CHD as it will provide important information for future development of dietary intervention.
METHODS: We searched the official Web sites and homepages of the responsible leading patient safety agencies of the three countries. We reviewed all publicly available guidelines, regulatory documents, government reports that included policies, guidelines, strategy papers, reports, evaluation programs, as well as scientific articles and gray literature related to the incident reporting system. We used the World Health Organization components of patient safety reporting system as the guidelines for comparison and analyzed the documents using descriptive comparative analysis.
RESULTS: Taiwan had the most incidents reported, followed by Malaysia and Indonesia. Taiwan Patient Safety Reporting (TPR) and the Malaysian Reporting and Learning System had similar attributes and followed the World Health Organization components for incident reporting. We found differences between the Indonesian system and both of TPR and the Malaysian system. Indonesia did not have an external reporting deadline, analysis and learning were conducted at the national level, and there was a lack of transparency and public access to data and reports. All systems need to establish a clear and structured incident reporting evaluation framework if they are to be successful.
CONCLUSIONS: Compared with TPR and Malaysian system, the Indonesian patient safety incident reporting system seemed to be ineffective because it failed to acquire adequate national incident reporting data and lacked transparency; these deficiencies inhibited learning at the national level. We suggest further research on the implementation at the hospital level to see how far national guidelines and policy have been implemented in each country.
MATERIALS AND METHODS: This collaborative research between the National Space Agency (ANGKASA), Universiti Teknologi MARA, Malaysia and Institute of Biomedical Problems (IBMP), Russia was conducted at the Russian Academy of Sciences IBMP, Moscow, Russia. Six multi-national cosmonauts were assigned to live in a ground-based confined module for 520 days. Standard exercise and diet regime were instituted throughout the isolation phase. Six age, ethnic and gender-matched healthy, free-living ground controls were recruited in parallel. Serial serum and whole blood were analysed for biomarkers of prothrombogenesis [plasminogen activator inhibitor-1 (PAI-1) and homocysteine] and oxidative stress [oxidised low-density lipoprotein (ox-LDL) and malondialdehyde (MDA)].
RESULTS: There were significantly lower concentrations of PAI-1 and homocysteine in cosmonauts during confinement compared to the controls. There were no significant differences seen in the concentrations of biomarkers of oxidative stress during confinement but there was a significant percentage change increment for serum MDA in cosmonauts.
CONCLUSION: Long-term confinement decreased the risk of prothrombogenesis and this could be attributed to the exercise and diet regime which includes omega-3 fatty acids supplementation given to the crew members during their confinement period. However, oxidative damage could not be excluded and may be attributed to the influence of psychological stress during this prolonged confinement.
OBJECTIVE: The objective of this study was to develop and validate an observation checklist for assessing the hygiene and sanitation of food preparation areas in preschools.
METHODOLOGY: The study was conducted in Kota Bharu Kelantan from March 2021 to February 2022. The development of the observation checklist was conducted in four stages: (1) the construction of domains and items from the existing literature, (2) content validation by six experts (using the item-level content validity index (I-CVI) and the scale-level content validity index (S-CVI), (3) face validation by 10 experts (using the item-level face validity index (I-FVI) and the scale-level face validity index (S-FVI)), and (4) reliability analysis (using the intercorrelation coefficient (ICC)). Four assessors performed the reliability analysis at two preschools.
RESULTS: The initial draft of the checklist contained three domains and 57 items: building and facility (10 subdomains and 38 items), process control (four subdomains and 12 items), and food handlers (one subdomain and seven items). The I-CVI scores for building and facility, process control, and food handlers were 0.97, 1.00, and 1.00, respectively, indicating good relevancy of items. The S-CVI value was 1.0 for all domains, showing good relevance of the items. The I-FVI above 0.8 and S-FVI values above 0.9 for all domains imply that the participants easily understood the checklist. The ICC for each domain was 0.847 (95% CI 0.716-0.902) for the building facility and 1.0 for process control and food handler, and the ICC for the three domains combined was 0.848 (95% CI 0.772-0.904). The final validated checklist consists of three domains with 57 items.
CONCLUSION: The newly developed observation checklist is a valid and reliable tool for assessing the hygiene and sanitation of preschool food preparation areas.
