Ong Eng Koon,Lok Si Ying Andrea,Ang Jie,Lai Kah Ho,Foon Xiang Lin,Lalit Kumar Radha Krishna 이화여자대학교 생명의료법연구소 2019 Asia Pacific Journal of Health Law & Ethics Vol.12 No.2

Proponents of physician-assisted suicide and euthanasia (PAS/E) assert that mentally competent terminally ill patients experiencing ‘intractable’ physical and/or existential suffering with no means of alleviating this suffering should be afforded the right to end their lives at a time and place of their choosing. A significant obstacle to legalising PAS/E has been the slippery slope argument that posits that gradual abuse of PAS/E is inevitable, leaving vulnerable patient groups of patients susceptible to its use. To distance this practice from the slippery slope, proponents of PAS/E proffer the concept of “Medical Aid-In-Dying” (MAID) that boasts of strict criteria for its use and forward evidence that its use in Oregon and the Netherlands has revealed no evidence of vulnerable patients being coerced into having PAS/E. This paper assesses the position and the assertions brought by proponents for the legalization of MAID in Singapore using an evidenced based socioculturally sensitive approach to contextualise these arguments. Socioculturally, prevailing Confucian- inspired family-centric practices hinders informed consent and creates coercive influences upon the decision- making process that will hinder effective consent for MAID whilst clinical evidence highlights inherent inaccuracies within determinations of prognosis and intractability that compromise legitimate application of MAID. This paper highlights the need for socioculturally sensitive, evidenced-based evaluation of all extrapolated data to consider the impact of prevailing mores and laws upon its application within the local scene. Singapore’s culture, clinical practice and laws do not support use of MAID locally.

Sun Exposure and the Risk of Prostate Cancer in the Singapore Prostate Cancer Study: a Case-control Study

Chia, Sin-Eng,Wong, Kin-Yoke,Cheng, Christopher,Lau, Weber,Tan, Puay-Hoon Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.7

Background: Most of the epidemiology studies on the effects of sun exposure and prostate cancer were conducted among the temperate countries of North America and Europe. Little is known about the influence on Asian populations. The purpose of current study was to evaluate any association of sun exposure with risk of prostate cancer in Chinese, Malays and Indians who reside in the tropics. Methods: The Singapore Prostate Cancer Study is a hospital-based case-control study of 240 prostate cancer incident cases and 268 controls conducted in Singapore between April 2007 and May 2009. Detailed information on outdoor activities in the sun, skin colour, sun sensitivity and other possible risk factors were collected in personal interviews. Cases were further classified by Gleason scores and TNM staging. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using unconditional logistic regression analysis, adjusted for age, ethnicity, education, family history of any cancers, BMI and skin colour. Results: We found that prostate cancer risk was increased in subjects with black/dark-brown eyes (OR 5.88, 95%CI 3.17-10.9), darker skin colour e.g. tan/dark brown/black (OR 7.62, 95%CI 3.41-17.0), frequent sunburn in lifetime (OR 4.30, 95%CI 1.7-11.2) and increased general sun exposure in adulthood per week (OR 2.03, 95%CI 1.09-3.81). The increased risk was consistent for high grade tumours and advanced stage prostate cancers. Conclusion: The findings from this study suggest that excessive sun exposure is a risk factor for prostate cancer in Asians.

Examining Knowledge, Skill, Stress, Satisfaction, and Self-Confidence Levels of Nursing Students in Three Different Simulation Modalities

Üzen Cura Şengül,Kocatepe Vildan,Yıldırım Dilek,Küçükakgün Hilalnur,Atay Selma,Ünver Vesile 한국간호과학회 2020 Asian Nursing Research Vol.14 No.3

Purpose: The aim of this study was to compare the effect of different simulation modalities on knowledge, skill, stress, satisfaction, and self-confidence levels of students receiving undergraduate education in three nursing schools. Method: This was an experimental study. Students applied the scenario of “Respiratory Sounds Assessment” which was prepared according to three different simulation modalities. In the study, the standardized patient, high-fidelity simulation, and partial task trainer were used as simulation modalities. Results: An increase was observed in postpractice knowledge levels of the three groups which had similar knowledge levels before the practice. Virtual Analog Scale stress levels of the students in the standardized patient group were higher than those of others. The students’ mean scores of satisfaction in learning were higher in the standardized patient group. The students in the partial task trainer group had lower scores of self-confidence in learning. Skill scores of the students were lower in the standardized patient practice than those in others. Conclusion: Simulation-based experiences give students the opportunity of experiencing situations they may experience in the actual practice beforehand. Therefore, this may increase their performance in real practices, as reality increases in the standardized patient group.

Green Air Transport System: An Overview of Issues, Strategies and Challenges

Lay Eng Teoh,Hooi Ling Khoo 대한토목학회 2016 KSCE Journal of Civil Engineering Vol.20 No.3

Globally, the environmental sustainability of air transport is receiving greater concern nowadays owing to its critical impact on climate change. This paper provides an overview of the environmental (green) issues in relation to aviation activities, focusing on aircraft emission and noise. The influential factors of the respective green issue (including aircraft characteristics and operations) as well as the relevant mitigation strategies, ranges from the technological innovation, operational strategy, fleet planning to the policies, rules and regulations are discussed accordingly. Besides, mathematical modeling, statistical analysis and survey which emerge to be the main methodologies adopted to alleviate the green issues are also discussed in detailed. Concisely, the literatures reveal that there is no single strategy or approach that can be implemented to ease the green issue. Thus, integrated effort and commitment from the relevant parties are required to yield a greener system. By identifying the literature gaps and also the potential rooms for improvement under uncertainty, it is anticipated that this paper could provide some useful insights to the relevant parties in charting the effective strategies to attain a green air transport system.

Image-guided radiation therapy in lymphoma management

Eng, Tony,Ha, Chul S. The Korean Society for Radiation Oncology 2015 Radiation Oncology Journal Vol.33 No.3

Image-guided radiation therapy (IGRT) is a process of incorporating imaging techniques such as computed tomography (CT), magnetic resonance imaging (MRI), Positron emission tomography (PET), and ultrasound (US) during radiation therapy (RT) to improve treatment accuracy. It allows real-time or near real-time visualization of anatomical information to ensure that the target is in its position as planned. In addition, changes in tumor volume and location due to organ motion during treatment can be also compensated. IGRT has been gaining popularity and acceptance rapidly in RT over the past 10 years, and many published data have been reported on prostate, bladder, head and neck, and gastrointestinal cancers. However, the role of IGRT in lymphoma management is not well defined as there are only very limited published data currently available. The scope of this paper is to review the current use of IGRT in the management of lymphoma. The technical and clinical aspects of IGRT, lymphoma imaging studies, the current role of IGRT in lymphoma management and future directions will be discussed.

Drug-herb interactions: Mechanisms involved and clinical implications of five commonly and traditionally used herbs

Chin Eng Ong,Yan Pan 셀메드 세포교정의약학회 2014 셀메드 (CellMed) Vol.4 No.3

Herbal remedies are commonly used by patients worldwide. Because these herbal preparations share the same metabolic and transport proteins with prescribed medicines, the potential for a drug-herb interaction is substantial and is an issue of significant concern. This review paper summarizes drug-herb interactions involving inhibition or induction of cytochrome P450 enzymes, drug transporters as well as modulation of drug pharmacodynamics. An increasing number of in vitro and animal studies, case reports and clinical trials evaluating such interactions have been reported, and implications of these studies are discussed in this review. The most commonly implicated drugs in the interaction include anticoagulants, antiplatelets, immunosuppressants, anti-neoplastics, protease inhibitors, and some antidepressants. Pharmacokinetic and/or pharmacodynamic interactions of five commonly used herbal remedies (danshen, garlic, Ginkgo biloba, ginseng, and St John’s wort) with these drugs are presented, with focus of discussion being the potentials for interaction, their mechanisms and clinical implications. There is a necessity for adequate pharmacovigilance to be carried out in minimizing unanticipated but often preventable drug-herb interactions.

Experimental and Numerical Modeling on Fatigue Damage in FRP and PM Confinement Tilt’s Fulcrum RC Segments under Humid and Constant Amplitude Loading

Tian Zi Eng,Peiwei Gao,Qiaorong Zhu,Axiang Zhu 대한토목학회 2019 KSCE JOURNAL OF CIVIL ENGINEERING Vol.23 No.8

It is a stringent challenge to swiftly rehabilitate and strengthen the concrete segments on the metro tunnel that are under the humid environment and vibration fatigue by the locomotives. By means of fatigue experiments under the constant amplitude loading, the repair materials (fiber reinforced polymer (FRP) and polymer matrix (PM)) which can be moisture proof and resist the cyclic load are introduced. Hereafter, a fatigue model of tilt’s fulcrum reinforced concrete (RC) segments under constant amplitude loading are proposed by the calibration of S-N curves through these fatigue test. The fatigue model explains for the (a) scope of pre-damage, (b) mechanical properties of the repaired concrete segments, such as the specific rupture times of cycle and stress-crack opening relation, and (c) effective plastic strain behavior of the RC segments. The results show that the purely PM is an excellent candidate for repairing the fatigue loaded damaged RC segment. It (L-4-2) had an average mechanical behavior for cyclic load bearing compared with the remaining specimens. On the other hand, the numerical model predictions had an approximately 96.00% of agreement with the corresponding test results.
