Oral health knowledge, attitudes and behaviours of adults: Findings from a National Oral Health Survey in Singapore. Community Dent Oral Epidemiol 2024; 52:292-301. [PMID: 38351568 DOI: 10.1111/cdoe.12947] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 01/22/2024] [Accepted: 02/01/2024] [Indexed: 05/16/2024]
Abstract
OBJECTIVES Prevention complements the curative management of oral diseases. Effective preventive interventions involve the adoption of oral health promoting behaviours. Little is known about the awareness of oral disease and its prevention among Singaporean adults as well as their prevailing oral health attitudes and behaviours. The aim of the study was to describe the oral health knowledge, attitudes and behaviours of adults in Singapore. METHODS A random sample of adults (≥21 years old) in Singapore was selected to complete an interviewer-administered questionnaire. The questionnaire gathered information about their knowledge of the aetiology, signs and symptoms as well as prevention of dental caries and periodontal disease; attitudes about the value of teeth, locus of control in maintaining oral health and oral health behaviours including toothbrushing, flossing and dental attendance. RESULTS A total of 1196 adults of weighted mean age 48 years old with almost equal proportions of males and females responded to the questionnaire. Participants were more unaware about the causes of periodontal disease (25.7%) than dental caries (4%). While more than 90% of participants felt that healthy teeth were important and could affect their overall health, many (67.0%) felt it was natural to lose their teeth with old age. Among the participants, 83.5% brushed their teeth twice a day; 41.9% flossed their teeth and 53.9% visited the dentist at least once a year. CONCLUSIONS The study findings showed good knowledge around dental caries but some gaps around periodontal disease. It also found that participants perceived having limited control over preventing tooth loss. Irregular dental attendance and poor denture wearing habits were also noted. The findings shed light on key areas to focus on through oral health promotion to improve overall oral health.

Trajectories of body mass index before the diagnosis of type 2 diabetes in a cohort of Taiwanese adults. Obes Res Clin Pract 2024; 18:21-27. [PMID: 38331596 DOI: 10.1016/j.orcp.2024.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 01/18/2024] [Accepted: 02/01/2024] [Indexed: 02/10/2024]
Abstract
BACKGROUND Although the prevalence of overweight/obesity is lower in Asian countries, the risk of type 2 diabetes (T2DM) is disproportionally higher. We identified and characterized the trajectory patterns of body mass index (BMI) before the onset of T2DM in a Taiwanese population. METHODS Using the Taiwan MJ cohort study, we sampled the health examination data of 22,934 participants, including 7618 cases of T2DM and 15,316 controls. We used latent class trajectory analysis to identify distinct groups of pre-disease BMI trajectory. To compare the trajectories of cardiometabolic risk factors among different groups, we used linear mixed-effects models. RESULTS These 22,934 participants included 13,074 men (57%) and 9860 women (43%) who were on average followed for 9.0 years. We identified three distinct pre-disease BMI trajectories in cases: "stable overweight" (n = 7016, 92.1%), "weight gain" (n = 333, 4.4%) and "obesity" (n = 269, 3.5%). The "stable overweight" group had a mean BMI of 24.6 kg/m2 at 15 years prior to diagnosis, had a 1.2 unit increase during follow-up, and had a mean BMI of 25.8 kg/m2 at the time of diagnosis. The "weight gain" group had the most increasing trends in blood pressure/low-density lipoprotein cholesterol over time. CONCLUSION The BMI trajectory patterns among individuals who later developed diabetes in Taiwan seemed comparable to that of Western populations, but our population developed T2DM at a much lower BMI. Given that most cases belong to the "stable overweight" group, we also support using a population-based strategy for diabetes prevention instead of focusing on the high risk individuals.

Abstract
OBJECTIVE Prior research suggests that children with a low socioeconomic status (SES) background are at an increased risk for special healthcare needs. Conversely, for hypersensitivity-related diseases, many studies reported a lower risk among children with lower SES according to the hygiene hypothesis. We aimed to evaluate the association between SES and several hypersensitivity diseases and autism in a representative American sample. METHODS We used data from the 2016, 2017 and 2018 US National Survey of Children's Health. A total of 102,341 children aged 0-17 years were included. The dependent variables were doctor-diagnosed allergies, arthritis, asthma, diabetes, and autism. The main SES indicators were family poverty levels, highest education of the reported adults and difficulty in family income. Our analysis used logistic regression that accounted for the survey sampling design. RESULTS The sample had a mean age of 9.4 ± 5.3 years. The weighted prevalence for allergies was 24.4%, 0.3% for arthritis, 11.9% for asthma, 0.5% for diabetes and 2.6% for autism. Children with adults reporting higher educational levels had greater odds of allergies (adjusted odds ratio and 95% CI: 1.48, 1.23-1.78) than those with lower educational levels. But for all other diseases, most findings suggested that a higher odds of disease was associated with lower SES instead of higher SES. CONCLUSIONS A low SES background remains an important risk factor for hypersensitivity diseases in children. Most of our results suggested that children with low SES were associated with a higher risk of hypersensitivity diseases and autism.

Trends in the distribution of body mass index, waist circumference and prevalence of obesity among Taiwanese adults, 1993–2016. PLoS One 2022; 17:e0274134. [PMID: 36084122 PMCID: PMC9462812 DOI: 10.1371/journal.pone.0274134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Accepted: 08/23/2022] [Indexed: 11/18/2022] Open
Abstract
Background Differences in the prevalence of general and abdominal obesity by subgroups such as age, sex, and education have been reported worldwide. Most studies in Taiwan regarding obesity prevalence were targeted at school-aged children or without further stratification by subgroups. Our aim was to examine the age-specific secular trend of body mass index (BMI), waist circumference (WC), and obesity prevalence stratified by sex, education and urbanization levels in Taiwanese adults. Methods We used three waves of nationally representative population from the Nutrition and Health Survey in Taiwan (NAHSIT) 1993–1996 (n = 2 989), 2005–2008 (n = 2 495), and 2013–2016 (n = 2 880). The data included standardized measurement of body weight, height, and WC. We conducted a serial cross-sectional analysis among adults aged 20 years or above to examine the age-specific trends of BMI, WC, and the prevalence of underweight, overweight, general obesity, and abdominal obesity with stratification by sex, education, and urbanization levels. Results The general obesity prevalence was 16%, 21%, and 20% and the abdominal obesity prevalence was 27%, 42%, and 47% in the 1993–1996, 2005–2008, and 2013–2016 surveys, respectively. The age-specific secular trend of BMI differed across subgroups; however, the trend of WC increased rapidly regardless of subgroups, except for women aged ≥60 years. The general obesity prevalence increased noticeably among men, younger- and middle-age adults with high school or higher education, middle- and older-age adults with lower than high school education, people <39 and ≥50 years of age residing in rural areas, and among those between 30 and 59 and ≥70 years of age residing in urban areas. Conclusions Although the increasing trend of general obesity prevalence was levelling off among several subgroups, the abdominal obesity prevalence increased significantly and rapidly in Taiwan. Future research in developing effective weight and WC control interventions tailored to different subgroups is urgently needed.

Birth cohort, sex and educational disparities in the trajectories of body mass index in Taiwan: a longitudinal study. BMC Public Health 2022; 22:409. [PMID: 35227238 PMCID: PMC8886784 DOI: 10.1186/s12889-022-12762-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Accepted: 02/10/2022] [Indexed: 11/10/2022] Open
Abstract
Background Taiwan has gone through rapid industrialization, urbanization and economic growth in the 20th and early 21st centuries. Therefore, the population has experienced significant changes in the physical and social environment during the life course, which may affect the overall adiposity. Our aim was to examine the age trajectories of height, weight and body mass index (BMI) in the Taiwanese population and to explore the influences of sex, birth cohort and education. Methods The sample comprised 572,358 residents between 20 and 94 years of age in Taiwan who attended at least one health examination during 1996 to 2017 in a cohort study. Repeated measures of body weight and height were collected using an auto-anthropometer. We conducted a series of linear mixed-effects growth curve models to examine the trajectory of height, weight, and BMI across the life course with stratification by sex. Results Age-related trajectories of BMI differed between men and women and stronger cohort effects were observed among men, with younger cohorts having higher BMI. After holding cohort and age variables constant, men with junior high or lower education were shorter, thinner and had higher BMI than men with university or higher education (effect sizes: − 3.138 cm, p < 0.001; − 2.277 kg, p < 0.001; 0.121 kg/m2, p < 0.001, respectively). Women with junior high or lower education were shorter, heavier and had higher BMI than women with university or higher education (effect sizes: − 2.368 cm, p < 0.001; 2.417 kg, p < 0.001; 1.691 kg/m2, p < 0.001, respectively). The educational disparities in BMI were found to be larger among women. Conclusions Our findings suggest that younger generations, especially men, and lower educational level individuals, particularly women, have increasing levels of BMI. The influence of age and cohort effects together with sex and educational disparities on adiposity should be highlighted when designing future interventions and policies regarding overweight and obesity.

Oral cancer knowledge and screening behavior among smokers and non-smokers in rural communities. BMC Cancer 2021; 21:430. [PMID: 33879128 PMCID: PMC8056680 DOI: 10.1186/s12885-021-08198-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Accepted: 04/13/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Research suggests having an oral and pharyngeal cancer (OPC) examination for early diagnosis can increase survival rate. However, the OPC screening rate is low in certain populations. To improve OPC screening rate, this study identified factors that are associated with having an OPC examination. METHODS Participants with landlines and aged 25 years and older were recruited from six northern Florida counties. Bivariate and logistic regressions were used to predict the outcome of whether the participants had ever had an OPC examination as well as whether participants had ever heard of an OPC examination. RESULTS Of 2260 participants with a mean age of 55.9 ± 15.0 years, the majority of participants never smoked (53.4%), self-identified as Whites (70.6%), and had some college or 2-year degree education (30.3%). Smokers were significantly less likely to have ever heard of an OPC examination than those who never smoked. Significant interaction between smoking status and race, and smoking status and social support interaction were found. Whites who never smoked were more likely to have had an OPC examination than non-Whites who never smoked. Former and current smokers with greater social support were more likely to have had an OPC examination than those with lower social support. CONCLUSION The findings from this study inform the need to enhance the awareness of having an OPC examination among smokers and to reduce barriers for racial minority populations to receive an OPC examination. Future research is warranted to develop interventions to target certain populations to improve the rate of OPC examination.

A comparative study on the clinical features of COVID-19 with non-SARS-CoV-2 respiratory viral infections. J Med Virol 2020; 93:1548-1555.

Abstract
During this coronavirus disease 2019 (COVID-19) pandemic, physicians have the important task of risk stratifying patients who present with acute respiratory illnesses. Clinical presentation of COVID-19, however, can be difficult to distinguish from other respiratory viral infections. Thus, identifying clinical features that are strongly associated with COVID-19 in comparison to other respiratory viruses can aid risk stratification and testing prioritization especially in situations where resources for virological testing and resources for isolation facilities are limited. In our retrospective cohort study comparing the clinical presentation of COVID-19 and other respiratory viral infections, we found that anosmia and dysgeusia were symptoms independently associated with COVID-19 and can be important differentiating symptoms in patients presenting with acute respiratory illness. On the other hand, laboratory abnormalities and radiological findings were not statistically different between the two groups. In comparing outcomes, patients with COVID-19 were more likely to need high dependency or intensive care unit care and had a longer median length of stay. With our findings, we emphasize that epidemiological risk factors and clinical symptoms are more useful than laboratory and radiological abnormalities in differentiating COVID-19 from other respiratory viral infections.

Abstract
Objective: This systematic review synthesizes factors related to nicotine replacement therapy (NRT) use among adolescents seeking to quit smoking, using the social–ecological model as a guiding framework. Data Source: Searches of PubMED, ProQuest, EBSCOhost, and ERIC were conducted in July 2016. Study Inclusion and Exclusion Criteria: Original studies of cigarette smokers younger than 18 years that discussed NRT were included. Data Extraction: Two reviewers individually extracted study purpose, sample, design, and results. Data Synthesis: Factors were categorized by social–ecological model level and summarized. Results: A total of 103 907 articles were identified during initial search. After narrowing to peer-reviewed articles in English and eliminating reviews and adult-only studies, we reviewed 51 articles. These 51 articles identified factors from studies at each level of the social–ecological model: intrapersonal ( k = 20), interpersonal ( k = 2), organizational ( k = 7), community ( k = 11), and public policy ( k = 14). Conclusion: Findings provide insight into the applicability of NRT for adolescent smoking cessation, and factors by social–ecological model level highlight areas for additional research. Future adolescent NRT studies should assess factors at the interpersonal, organizational, and community levels, as well as the interactions between levels.

Cultural variation in antismoking video ads between the United States, Taiwan, and China. HEALTH EDUCATION RESEARCH 2016; 31:603-613.

Abstract
Antitobacco advertisement components, including types of messages and advertising appeals, have not been evaluated among multinational groups. This study identified and compared the content of antismoking video ads across three countries. We reviewed 86 antismoking video advertisements for the following information: severity of the consequences of smoking, types of risks, appeals to audiences' self-efficacy, benefits of not smoking, targeted social-ecological level and types of message appeal used. Two researchers independently coded each advertisement with an average inter-coder reliability of 0.79.Analyses showed a variety of focuses: smoking-related health risks (86%), severe consequences of smoking (54.7%), self-efficacy beliefs (40.7%) and benefits of not smoking (84.9%). Compared to the United States and Taiwanese ads, Chinese ads were more likely to target at the community level (10% versus 23.3% versus 47.2%). Additionally, 55% of the United States ads used the fear approach, whereas 61.1% of Chinese ads used the social approach. Taiwanese ads were evenly distributed among both approaches. In conclusion, the countries used different targeting strategies and approaches during message delivery. Although China's neighboring country, Taiwan, has many similar cultural aspects, including the same language, they are greatly influenced by US antitobacco campaigns. As a result, Taiwan's tobacco campaigns appear to have similar components to both China and the United States. Further research is warranted to understand the reasons for each method and to examine the effectiveness of the ads in reducing smoking rates.

Nano Josephson superconducting tunnel junctions in YBa2Cu3O(7-δ) directly patterned with a focused helium ion beam. NATURE NANOTECHNOLOGY 2015; 10:598-602.

Abstract
Since the discovery of the high-transition-temperature superconductors (HTSs), researchers have explored many methods to fabricate superconducting tunnel junctions from these materials for basic science purposes and applications. HTS circuits operating at liquid-nitrogen temperatures (∼77 K) would significantly reduce power requirements in comparison with those fabricated from conventional superconductors. The difficulty is that the superconducting coherence length is very short and anisotropic in these materials, typically ∼2 nm in the a-b plane and ∼0.2 nm along the c axis. The electrical properties of Josephson junctions are therefore sensitive to chemical variations and structural defects on atomic length scales. To make multiple uniform HTS junctions, control at the atomic level is required. In this Letter we demonstrate all-HTS Josephson superconducting tunnel junctions created by using a 500-pm-diameter focused beam of helium ions to directly write tunnel barriers into YBa2Cu3O(7-δ) (YBCO) thin films. We demonstrate the ability to control the barrier properties continuously from conducting to insulating by varying the irradiation dose. This technique could provide a reliable and reproducible pathway for scaling up quantum-mechanical circuits operating at liquid-nitrogen temperatures, as well as an avenue to conduct novel planar superconducting tunnelling studies for basic science.

Photoactivation of lysosomally sequestered sunitinib after angiostatic treatment causes vascular occlusion and enhances tumor growth inhibition. Cell Death Dis 2015; 6:e1641. [PMID: 25675301 PMCID: PMC4669819 DOI: 10.1038/cddis.2015.4] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2014] [Revised: 12/09/2014] [Accepted: 12/22/2014] [Indexed: 11/17/2022]
Abstract
The angiogenesis inhibitor sunitinib is a tyrosine kinase inhibitor that acts mainly on the VEGF and PDGF pathways. We have previously shown that sunitinib is sequestered in the lysosomes of exposed tumor and endothelial cells. This phenomenon is part of the drug-induced resistance observed in the clinic. Here, we demonstrate that when exposed to light, sequestered sunitinib causes immediate destruction of the lysosomes, resulting in the release of sunitinib and cell death. We hypothesized that this photoactivation of sunitinib could be used as a vaso-occlusive vascular-targeting approach to treating cancer. Spectral properties of sunitinib and its lysosomal accumulation were measured in vitro. The human A2780 ovarian carcinoma transplanted onto the chicken chorioallantoic membrane (CAM) and the Colo-26 colorectal carcinoma model in Balb/c mice were used to test the effects of administrating sunitinib and subsequently exposing tumor tissue to light. Tumors were subsequently resected and subject to immunohistochemical analysis. In A2780 ovarian carcinoma tumors, treatment with sunitinib+light resulted in immediate specific angio-occlusion, leading to a necrotic tumor mass 24 h after treatment. Tumor growth was inhibited by 70% as compared with the control group (**P<0.0001). Similar observations were made in the Colo-26 colorectal carcinoma, where light exposure of the sunitinib-treated mice inhibited tumor growth by 50% as compared with the control and by 25% as compared with sunitinib-only-treated tumors (N≥4; P=0.0002). Histology revealed that photoactivation of sunitinib resulted in a change in tumor vessel architecture. The current results suggest that the spectral properties of sunitinib can be exploited for application against certain cancer indications.

Abstract
Medical physics plays an essential role in modern medicine. This is particularly evident in cancer care where medical physicists are involved in radiotherapy treatment planning and quality assurance as well as in imaging and radiation protection. Due to the large variety of tasks and interests, medical physics is often subdivided into specialties such as radiology, nuclear medicine and radiation oncology medical physics. However, even within their specialty, the role of radiation oncology medical physicists (ROMPs) is diverse and varies between different societies. Therefore, a questionnaire was sent to leading medical physicists in most countries/areas in the Asia/Pacific region to determine the education, role and status of medical physicists.Answers were received from 17 countries/areas representing nearly 2800 radiation oncology medical physicists. There was general agreement that medical physicists should have both academic (typically at MSc level) and clinical (typically at least 2 years) training. ROMPs spent most of their time working in radiotherapy treatment planning (average 17 hours per week); however radiation protection and engineering tasks were also common. Typically, only physicists in large centres are involved in research and teaching. Most respondents thought that the workload of physicists was high, with more than 500 patients per year per physicist, less than one ROMP per two oncologists being the norm, and on average, one megavoltage treatment unit per medical physicist.There was also a clear indication of increased complexity of technology in the region with many countries/areas reporting to have installed helical tomotherapy, IMRT (Intensity Modulated Radiation Therapy), IGRT (Image Guided Radiation Therapy), Gamma-knife and Cyber-knife units. This and the continued workload from brachytherapy will require growing expertise and numbers in the medical physics workforce. Addressing these needs will be an important challenge for the future.

Abstract
Radiotherapy is one of the earliest fields in Medicine in which computers have made an inroad. The main uses of computers, which include treatment planning, dose calculations, localisation of tumours, verification of patient setups and radiation beam data acquisition, are highlighted in this paper. It is believed that a modern Radiotherapy department cannot function optimally without some form of computing facilities. With advances made in dose calculation algorithms, and in high performance computers, it is expected that the target of 3% accuracy dose calculations can be achieved in treatment planning.

Abstract
Twenty-five cases of choledochal cysts operated at the University Hospital between 1969 and 1981 were reviewed. Nineteen of the patients were females. An accurate pre-operative diagnosis of choledochal cyst was made in 10 patients (40%). We have found the 99Tcm-diethyl-IDA (EHIDA) scan to be the safest and most sensitive diagnostic tool. In recent years excision has been performed whenever possible in view of reports of malignancy developing in the cyst wall. It has a lower morbidity and re-operation rate compared to internal drainage. In excision we advise the use of a cuff of the cyst wall for a wider anastomosis. As the biliary tract shrinks and retracts into the porta following excision of the cyst, stricture formation may still occur despite a wide anastomosis.
