RESUMO
BACKGROUND: DEHP, a common plasticizer known for its hormone-disrupting properties, has been associated with asthma. However, a significant proportion of adult asthma cases are "non-atopic", lacking a clear etiology. METHODS: In a case-control study conducted between 2011 and 2015, 365 individuals with current asthma and 235 healthy controls from Kaohsiung City were enrolled. The control group comprised individuals without asthma, Type 2 Diabetes Mellitus (T2DM), hypertension, or other respiratory/allergic conditions. The study leveraged asthma clusters (Clusters A to F) established in a prior investigation. Analysis involved the examination of urinary DEHP metabolites (MEHP and MEHHP), along with the assessment of oxidative stress, sphingolipid metabolites, and inflammatory biomarkers. Statistical analyses encompassed Spearman's rank correlation coefficients, multiple logistic regression, and multinomial logistic regression. RESULTS: Asthma clusters (E, D, C, F, A) exhibited significantly higher ORs of MEHHP exposures compared to the control group. When considering asthma-related comorbidities (T2DM, hypertension, or both), patients without comorbidities demonstrated significantly higher ORs of the sum of primary and secondary metabolites (MEHP + MEHHP) and MEHHP compared to those with asthma comorbidities. A consistent positive correlation between urinary HEL and DEHP metabolites was observed, but a consistent negative correlation between DEHP metabolites and selected cytokines was identified. CONCLUSION: The current study reveals a heightened risk of MEHHP and MEHP + MEHHP exposure in specific asthma subgroups, emphasizing its complex relationship with asthma. The observed negative correlation with cytokines suggests a new avenue for research, warranting robust evidence from epidemiological and animal studies.

OBJECTIVES: To provide updated statistics of oral cancer incidence and mortality in Taiwan, and to describe recent developments for oral cancer control to reduce oral cancer incidence and mortality. METHODS: The Taiwan Cancer Registry Annual Report 2023, the Taiwan Cancer Registry Online Interactive Search System, and the 2023 Health Promotion Administration Annual Report are consulted and summarized. A literature search using PubMed was also conducted to identify Taiwan oral cancer control-related studies. RESULTS: Taiwan, with a long history of areca/betel quid chewing, has battled with oral cancer for decades. In 2021, the male lip and oral cavity cancer incidence is 29.77 (per 100,000 persons) and mortality is 11.25. Over these years, the male chewing prevalence was reduced to 6.2% in 2018. Taiwan has a sustained national oral cancer screening programme provided to high-risk groups biennially. CONCLUSIONS: Although the age-standardized incidence rates have been slowly decreasing since 2009, due to Taiwan's ageing population, the actual oral cancer burden is still stringent. The collaboration of multi-ministries and agencies on promoting areca nut and betel quid control, improving oral cancer awareness, and delivering cancer care remains essential to prevent oral cancer and reduce oral cancer deaths.
RESUMO
OBJECTIVE: This study evaluated the effectiveness of face-to-face (F2F) and online OralDETECT training programme in enhancing early detection skills for oral cancer. METHODS: A total of 328 final-year dental students were trained across six cohorts. Three cohorts (175 students) received F2F training from the academic years 2016/2017 to 2018/2019, and the remaining three (153 students) underwent online training during the Covid-19 pandemic from 2019/2020 to 2021/2022. Participant scores were analysed using the Wilcoxon signed rank test, the Mann-Whitney test, Cohen's d effect size, and multiple linear regression. RESULTS: Both F2F and online training showed increases in mean scores from pre-test to post-test 3: from 67.66 ± 11.81 to 92.06 ± 5.27 and 75.89 ± 11.03 to 90.95 ± 5.22, respectively. Comparison between F2F and online methods revealed significant differences in mean scores with large effect sizes at the pre-test stage (p < 0.001), while significant differences with small effect sizes were noted for post-test 1 (p = 0.002) and post-test 3 (p = 0.041). Regression analysis indicated that the delivery method is associated with the participants' final scores. CONCLUSION: F2F and online versions of the OralDETECT training programme significantly enhance participants' knowledge and skills in oral cancer detection. Although F2F appeared to be more effective, the difference was not substantial enough to be considered educationally meaningful.
RESUMO
BACKGROUND: Adult asthma is phenotypically heterogeneous with unclear aetiology. We aimed to evaluate the potential contribution of environmental exposure and its ensuing response to asthma and its heterogeneity. METHODS: Environmental risk was evaluated by assessing the records of National Health Insurance Research Database (NHIRD) and residence-based air pollution (particulate matter with diameter less than 2.5 micrometers (PM2.5) and PM2.5-bound polycyclic aromatic hydrocarbons (PAHs)), integrating biomonitoring analysis of environmental pollutants, inflammatory markers and sphingolipid metabolites in case-control populations with mass spectrometry and ELISA. Phenotypic clustering was evaluated by t-distributed stochastic neighbor embedding (t-SNE) integrating 18 clinical and demographic variables. FINDINGS: In the NHIRD dataset, modest increase in the relative risk with time-lag effect for emergency (N=209 837) and outpatient visits (N=638 538) was observed with increasing levels of PM2.5 and PAHs. Biomonitoring analysis revealed a panel of metals and organic pollutants, particularly metal Ni and PAH, posing a significant risk for current asthma (ORs=1.28-3.48) and its severity, correlating with the level of oxidative stress markers, notably Nε-(hexanoyl)-lysine (r=0.108-0.311, p<0.05), but not with the accumulated levels of PM2.5 exposure. Further, levels of circulating sphingosine-1-phosphate and ceramide-1-phosphate were found to discriminate asthma (p<0.001 and p<0.05, respectively), correlating with the levels of PAH (r=0.196, p<0.01) and metal exposure (r=0.202-0.323, p<0.05), respectively, and both correlating with circulating inflammatory markers (r=0.186-0.427, p<0.01). Analysis of six phenotypic clusters and those cases with comorbid type 2 diabetes mellitus (T2DM) revealed cluster-selective environmental risks and biosignatures. INTERPRETATION: These results suggest the potential contribution of environmental factors from multiple sources, their ensuing oxidative stress and sphingolipid remodeling to adult asthma and its phenotypic heterogeneity.

OBJECTIVE: To describe the development of a platform for image collection and annotation that resulted in a multi-sourced international image dataset of oral lesions to facilitate the development of automated lesion classification algorithms. MATERIALS AND METHODS: We developed a web-interface, hosted on a web server to collect oral lesions images from international partners. Further, we developed a customised annotation tool, also a web-interface for systematic annotation of images to build a rich clinically labelled dataset. We evaluated the sensitivities comparing referral decisions through the annotation process with the clinical diagnosis of the lesions. RESULTS: The image repository hosts 2474 images of oral lesions consisting of oral cancer, oral potentially malignant disorders and other oral lesions that were collected through MeMoSA® UPLOAD. Eight-hundred images were annotated by seven oral medicine specialists on MeMoSA® ANNOTATE, to mark the lesion and to collect clinical labels. The sensitivity in referral decision for all lesions that required a referral for cancer management/surveillance was moderate to high depending on the type of lesion (64.3%-100%). CONCLUSION: This is the first description of a database with clinically labelled oral lesions. This database could accelerate the improvement of AI algorithms that can promote the early detection of high-risk oral lesions.

OBJECTIVE: To evaluate the accuracy of MeMoSA®, a mobile phone application to review images of oral lesions in identifying oral cancers and oral potentially malignant disorders requiring referral. SUBJECTS AND METHODS: A prospective study of 355 participants, including 280 with oral lesions/variants was conducted. Adults aged ≥18 treated at tertiary referral centres were included. Images of the oral cavity were taken using MeMoSA®. The identification of the presence of lesion/variant and referral decision made using MeMoSA® were compared to clinical oral examination, using kappa statistics for intra-rater agreement. Sensitivity, specificity, concordance and F1 score were computed. Images were reviewed by an off-site specialist and inter-rater agreement was evaluated. Images from sequential clinical visits were compared to evaluate observable changes in the lesions. RESULTS: Kappa values comparing MeMoSA® with clinical oral examination in detecting a lesion and referral decision was 0.604 and 0.892, respectively. Sensitivity and specificity for referral decision were 94.0% and 95.5%. Concordance and F1 score were 94.9% and 93.3%, respectively. Inter-rater agreement for a referral decision was 0.825. Progression or regression of lesions were systematically documented using MeMoSA®. CONCLUSION: Referral decisions made through MeMoSA® is highly comparable to clinical examination demonstrating it is a reliable telemedicine tool to facilitate the identification of high-risk lesions for early management.

BACKGROUND: Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are used in treating cardiovascular diseases. Previous studies indicated that ACEIs/ARBs may benefit cancer patients by inhibiting tumor angiogenesis and proliferation. The effect of ACEIs/ARBs on cancer survival in esophageal and gastric cancer is still unclear. This study is to investigate the association between ACEIs/ARBs usage and esophageal and gastric cancer prognosis. METHODS: This retrospective cohort study identified esophageal and gastric cancer patients during 2008-2016 from the Taiwan Cancer Registry, and obtained medication usage and follow-up information from the National Health Insurance Research Database and Death Registry. Analysis groups were defined as ACEIs/ARBs user or non-user based on the usage of ACEIs/ARBs within the 6 months after cancer diagnosis. The stabilized inverse probability of treatment weighting using propensity scores was applied to balance covariates between study groups. We also used Kaplan-Meier estimates and Cox regression to compare survival outcome and estimate hazard ratios (HRs). RESULTS: We identified 14,463 and 21,483 newly-diagnosed esophageal and gastric cancer patients during 2008-2016. ACEIs/ARBs users were associated with lower risk of cancer-specific mortality, although only significantly in gastric cancer (gastric: adjusted HR = 0.87, 95% CI = 0.78-0.97; esophageal: adjusted HR =0.88, 95% CI = 0.76-1.02). A better survival outcome was observed among patients who received higher cumulative defined daily dose of ACEIs/ARBs. CONCLUSIONS: We found that using ACEIs/ARBs after cancer diagnosis were associated with lower risk of mortality. Our results add to the knowledge of the benefit of ACEIs/ARBs against mortality in individuals with esophageal/gastric cancer patients with hypertension.

AIMS: This study aimed to evaluate and compare the effectiveness and safety between clopidogrel and ticagrelor in acute coronary syndrome (ACS) with renal dysfunction. METHODS: We conducted a retrospective cohort study on patients on chronic dialysis and whose admission diagnosis between 1 July 2013 and 31 December 2016 included ACS. The primary effectiveness endpoint was a major adverse cardiovascular event (MACE), and the primary safety endpoint was a major bleeding event. The application of propensity scores through the inverse probability of treatment weighting (IPTW) was applied to the study groups. Cox regression was used to estimate hazard ratios (aHRs) of study endpoints. In addition, the competing risk was adjusted using the Fine and Gray competing risk model. RESULTS: There were 1915 patients in the clopidogrel group and 270 patients in the ticagrelor group. At 12 months, the ticagrelor group had higher risks for MACE (aHR with IPTW: 1.29; 95% CI 1.16-1.44); death (aHR with IPTW: 1.65; 95% CI 1.47-1.86) and cardiac death (subdistribution HR [SHR] with IPTW: 1.64; 95% CI 1.41-1.91), compared with those in the clopidogrel group. For major bleeding event, the risk was significantly higher with ticagrelor than with clopidogrel (SHR with IPTW: 1.49; 95% CI 1.34-1.65). In terms of the risk for any bleeding event, there was no significant difference between the two groups (SHR with IPTW: 1.05; 95% CI 0.95-1.17). CONCLUSIONS: Compared with clopidogrel, ticagrelor was associated with higher MACE, death, cardiac death and major bleeding risk within 12 months in patients with ACS and on dialysis.

OBJECTIVES: Oral squamous cell carcinoma (OSCC) is a multifactorial disease. The individual effect of each risk factor for OSCC may be conditioned by the frequency of other factors. The objective of this study was to identify the association between chronic mechanical irritation (CMI) and OSCC and to analyse the influence of CMI on other important risk factors for OSCC. MATERIALS AND METHODS: A prospective and age/sex-matched case-control study was performed in two institutions from Argentina between 2009 and 2019, with consecutive and newly diagnosed OSCC. The frequencies of tobacco, alcohol, and CMI were analysed using conditional logistic regression. Cumulative tobacco consumption and the presence of CMI were analysed using the Mann-Whitney test. RESULTS: CMI and OSCC were associated with an OR of 7.02 (95% CI 3.57-13.78, p < 0.001). The combination of CMI and alcohol demonstrated the highest risk of OSCC (OR 53.83, CI 95% 8.04-360, p < 0.0001), followed by the combination of CMI, tobacco, and alcohol (OR 48.06, CI 95% 8.47-272, p < 0.0001). The combination of CMI and tobacco was also significant (OR 5.61, CI 95% 1.07-29.54, p = 0.042). Patients with CMI developed OSCC with less cumulative tobacco use compared with those without CMI. CONCLUSION: CMI is an independent risk factor for OSCC, and it could act as a risk modifier among tobacco and alcohol users having an enhancing effect. CLINICAL RELEVANCE: Elimination of CMI could decrease the risk of OSCC.

BACKGROUND/PURPOSE: Gay and bisexual men are at a higher risk of mental and physical health problems than heterosexual men, reporting higher frequencies of harassment and discrimination in both housing and employment domains. Psychological inflexibility/experiential avoidance (PI/EA) refers to behaviors that are rigidly guided by psychological reactions rather than direct contingencies or personal values; PI/EA referring to a key psychopathology behavior related to greater mental illness. The objective of the study was to examine the association of various types of harassment with PI/EA and the effects of multiple types and site harassment on PI/EA among Taiwanese emergent adult gay and bisexual men. METHODS: A total of 305 gay and bisexual men aged between 20 and 25 years were recruited into this study. The level of PI/EA and types of harassment were evaluated and further analysis the effect of harassment on PI/EA. RESULTS: Findings indicated that various types of harassment exerted significant effects on PI/EA in emergent adult gay and bisexual men; furthermore, the effect was cumulative. The result also revealed that victims of verbal ridicule and relational exclusion, victims of physical aggression and theft of belongings, and victims of cyber harassment had significantly higher PI/EA. CONCLUSION: Harassment experiences appeared to be significantly associated with PI/EA, and the effects could be cumulative. It would be beneficial to construct a friendly world for emergent adult gay and bisexual men. Evaluation and intervention with PI/EA improvement should be considered for emergent adult gay and bisexual men with traditional and cyber harassment experiences.

BACKGROUND/PURPOSE: Three first-line epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are widely available to treat advanced lung adenocarcinoma harboring EGFR mutation. However, studies comparing efficacy or effectiveness of these EGFR TKIs came out with inconclusive results. METHODS: In this real-world data analysis with a nationwide retrospective cohort design, adult patients with newly diagnosed advanced lung adenocarcinoma with EGFR mutation between 2011 and 2016, who received a first-line EGFR TKI, were included. Overall survival (OS) and time to next treatment (TTNT) were compared between patients receiving different EGFR TKIs after overlap weighting. RESULTS: We enrolled 10,431 patients, including 6,230, 2,359, and 1842 in gefitinib, erlotinib, and afatinib groups, respectively. The median (95% confidence interval [CI]) OS were 24.2 (22.9-26.2), 25.7 (24.0-27.9), and 29.1 (25.8-32.1) months for those receiving gefitinib, erlotinib, and afatinib, respectively (p = 0.001). The hazard ratios (95% CI) for the afatinib group were 0.85 (0.74-0.98) and 0.91 (0.79-1.05) comparing with the gefitinib and erlotinib groups, respectively. The median (95% CI) TTNT were 10.9 (10.4-11.2), 11.7 (11.3-12.1), 13.4 (12.5-14.3) months for those receiving gefitinib, erlotinib, and afatinib, respectively (p < 0.001). The hazard ratios (95% CI) for the afatinib group were 0.79 (0.70-0.88) and 0.89 (0.79-1.00) comparing with the gefitinib and erlotinib groups, respectively. There were 6111 (59%) patients receiving subsequent therapies, and the majority of them received a second-line chemotherapy, particularly platinum-based chemotherapy. CONCLUSION: Afatinib, compared with gefitinib, might provide better effectiveness as the first-line targeted therapy for patients of advanced lung adenocarcinoma with EGFR mutation.

BACKGROUND: Neuropsychiatric symptoms (NPS) could increase mortality risk in people with dementia due to Alzheimer's disease (AD). However, whether NPS affects mortality risk in people with mild cognitive impairment (MCI) and whether any specific syndrome of NPS influences this risk are still unclear. METHODS: In total, 984 participants with dementia due to AD, 338 with MCI, and 365 controls were enrolled. Over a mean of 5-year follow-up, cause of death data were obtained from the Ministry of Health and Welfare in Taiwan. NPS were assessed using Neuropsychiatric Inventory Questionnaire (NPI-Q), and psychosis, mood, and frontal domain scores were determined. Survival analyses were conducted to determine the hazard ratio (HR) of death. RESULTS: In controlled analyses, HR of death for AD was 2.19 (95% confidence interval [CI] = 1.29-3.71) compared with the control group, whereas no statistical significance was noted for the MCI group. A high NPI-Q score (above the median score) increased mortality risk for both the MCI and AD groups, with HRs of 2.32 (95% CI = 1.07-5.03) and 2.60 (95% CI = 1.51-4.47), respectively. Among NPI-Q domain scores, only high mood domain, but not psychosis or frontal domain, scores increased death risk for both the MCI (HR = 2.89, 95% CI = 1.00-8.51) and AD (HR = 2.59, 95% CI = 1.47-4.55) groups. CONCLUSION: Mortality risk is high for patients with AD. Not only for AD, patients with MCI presenting with NPS, particularly mood symptoms, have high death risk.

Early diagnosis of oral cancer results in less aggressive treatment and improves the quality of life and overall 5-year survival rate. Well-trained dental professionals can play a crucial role in the early detection of oral cancers. The present study aims to determine the effectiveness of the training program "OralDETECT", a spaced repetitive, test-enhanced learning tool with a corrective feedback mechanism for early detection of oral cancer. Thirty-two dentists and 259 dental students from three Malaysian dental schools were involved in this study. All participants were trained and calibrated to recognize oral potentially malignant disorders (OPMD) and oral cancer using "OralDETECT", which is comprised of a series of pre-test, lecture, post-tests and review sessions. The percentage of correct answers (scores) for each test given by the participants was calculated and analysed using a paired t test. It was found that the overall percentage of diagnostic accuracy for both dental professionals and student groups increased to above 80% from the pre-tests to the final post-tests. There was a significant improvement in overall scores between the pre-tests and all three post-tests for the dental professional groups and the student groups. The diagnostic accuracy for individual OPMD and lesions suspicious of oral cancer also increased to above 80% for both groups. The results of our study demonstrate that the "OralDETECT" is an efficient and effective competency tool which can be used to train dental professionals and students for the early detection of OPMD and oral cancer.

Background and Objectives: Studies examining the importance of inflammatory markers before treatment as prognosticators of OSCC are available, but information on post-therapy inflammatory markers and their prognostic significance is limited. This study aimed to evaluate the prognostic abilities of pre- and post-treatment inflammatory markers in patients with OSCC. Materials and Methods: In this retrospective analysis, information on 151 OSCC patients' socio-demographic, clinico-pathological, recurrence, metastasis, and survival data were gathered from clinical records. A multivariable Cox proportional hazards regression (stepwise model) was conducted to identify the prognostic predictors of OS and DFS. The multivariable models' performances were evaluated using Harrell's concordance statistics. Results: For OS, high pre-treatment LMR (HR 3.06, 95%CI 1.56, 5.99), and high post-treatment PLC (HR 3.35, 95%CI 1.71, 6.54) and PLR (HR 5.26, 95%CI 2.62, 10.58) were indicative of a poor prognosis. For DFS, high pre-treatment SII (HR 2.59, 95%CI 1.50, 4.48) and high post-treatment PLC (HR 1.92, 95%CI 1.11, 3.32) and PLR (HR 3.44, 95%CI 1.98, 5.07) were associated with increased mortality. The fitness of the OS and DFS stepwise Cox regression models were proven with a time-dependent AUC of 0.8787 and 0.8502, respectively. Conclusions: High pre-treatment levels of LMR and SII and high post-treatment levels of PLC and PLR are independent predictors of a poor prognosis for patients with OSCC.

BACKGROUND: Previous studies have reported associations between hearing impairment (HI) and cognitive impairment, but the evidence is not conclusive while considering concurrent geriatric syndromes. Especially, evidence from previous studies rarely came from Asian studies. This study aimed to evaluate the independent effects of HI and hearing aid use on the incidence of cognitive impairment while considering most geriatric confounders. METHODS: This population-based, propensity-score matched cohort study used cohort from Waves IV-VII (1999-2011) survey of the Taiwan Longitudinal Study on Aging (TLSA). Cognitive impairment was identified based on Short Portable Mental Status Questionnaire (SPMSQ) scores. The hazard ratio (HR) was calculated using the Cox proportional hazard regression adjusting for age, sex, comorbidities, socioeconomic status, Center for Epidemiologic Studies Depression (CES-D) scores, the instrumental activities of daily living scale, mobility condition and quality of life. In addition, social support and participation were also considered as confounders in the analysis. To assess the robustness of our findings, we conducted a sensitivity analysis designed to access unmeasured confounding factors by calculating E-values. RESULTS: After 1:1 propensity-score matching, we included 709 participants in both the HI and non-HI groups with a mean age of 73.4 years and 39.4% of participants were female. The mean follow-up was 8.9 ± 3.9 years. The HI group had a higher incidence of cognitive impairment than the non-HI group (74.5% vs. 69.1%, respectively), with an adjusted HR of 1.16 (95% confidence interval [CI], 1.03-1.32) based on a 12-year follow up. The E-value was 1.45 for the estimate, which provided evidence for this study's robustness. Although, a subgroup analysis showed that hearing aid use was associated with lower incidences of cognitive impairment (66.3% vs. 75.6%) when compared to non-users in the HI group, the adjusted HR of 0.82 (95% CI, 0.61-1.09) revealed no significant differences. CONCLUSIONS: HI was an independent risk factor of incident cognitive impairment on top of concurrent geriatric syndromes. Early HI detection may thus be effective for preventing cognitive decline. Further studies are needed to evaluate the effect of hearing aid use on the prevention of cognitive decline.

AIM: The aim of this study was to investigate the associations between candidate gene variants and domains of neuropsychiatric symptoms (NPS) and the changes in these associations over a 1-year period. METHODS: Seven hundred and ninety-three Taiwanese participants (47.8% female) with Alzheimer's disease (AD) were enrolled. Genes associated with a risk of developing AD were selected as candidate genes. NPS were assessed using the Neuropsychiatric Inventory Questionnaire (NPI-Q), and the NPI-Q total score and sub-scores for the Psychosis, Mood, and Frontal Syndrome domains were calculated. RESULTS: Patients with AD and the APOE ε4 allele exhibited more obvious symptoms of psychosis. Mood symptoms were associated with CD33 rs3865444 and EPHA1 rs11767557, and frontal symptoms were associated with SORL1 rs3824968. A 1-year Time × Alleles interaction effect of CD33 rs3865444 on mood symptoms was discerned. CONCLUSION: Risk genes of AD, which are also associated with NPS, are APOE ε4 for psychosis, CD33 and EPHA1 for mood symptoms, and SORL1 for frontal symptoms. The association between CD33 and mood symptoms is dynamic and could change over 1 year; however, the results should be interpreted with caution because corrections for multiple comparisons were not performed.

Background: Effectiveness of oral cancer screening depends on identifying high-risk groups. People with betel quid chewing or cigarette smoking habits are often reluctant to attend screenings. Given that use of both substances is associated with certain occupations, a targeted approach should be applied to improve the effectiveness of screening programs. Objectives: This study sought to identify occupations with a high prevalence of betel quid chewing and cigarette smoking and to investigate their changing trends using the Taiwan National Health Interview Survey (NHIS) database. Methods: The NHIS database for 2009 and 2013 were used. We estimated prevalence of current betel quid and/or cigarette use among those aged 20-64 years old. Occupations were classified using the International Standard Classification of Occupations (ISCO-88). Statistical analyses included indirect standardized rates and cluster analysis of chewing/smoking habits. Results: Drivers, mobile-plant operators, and extraction and building trades workers had the highest prevalence of betel quid chewing and cigarette smoking (chewing: 30.92% and 29.62%; smoking: 61.16% and 62.22%). Many occupations had large indirect standardized rates for chewing but not smoking. Both habits are associated with each other (r = 0.81, p < 0.001). Use appeared to decrease based on comparison between 2009 and 2013. Conclusions: Drivers and construction laborers showed high prevalence of betel chewing and cigarette smoking. The chewing habit is actually more prevalent in several sub-occupations. The survey results also revealed lower attendance by construction laborers at oral cancer screenings. Oral cancer screening and awareness should be emphasized in the identified occupations.

Background: Areca nut (AN) and betel quid (BQ) chewing are ancient practices followed by an extensive proportion of the world's population. These practices are endemic in larger parts of South and Southeast Asia and selected Western Pacific countries. The prevalence of these habits varies across regions, age, gender, cultural practice, and socioeconomic status groups. Considerable variations exist between countries with respect to prevention/intervention programs, and policy guidelines of BQ usage. Objectives: (1) To provide an overview of the BQ chewing prevalence, practices, preventive interventions and policies in selected Asian and Western Pacific countries. (2) To explore the different terminologies associated with BQ use. Method: A narrative review of the current literature related to BQ, AN, and oral cancer was conducted by searching PUBMED, CINAHL, and GOOGLE databases. Results: The literature review revealed that the prevalence of BQ was found to be highest in Papua New Guinea, followed by Bangladesh, India, Pakistan, Myanmar and Sri Lanka. While, Cambodia, Malaysia, Indonesia and Taiwan had comparatively lower prevalence. Smokeless tobacco, BQ with tobacco, BQ without tobacco, AN were some of the terminologies used for BQ in various studies. Conclusions: The prevalence, and the interventional policies related to BQ and AN chewing habits varies widely among the selected countries. With the increasing awareness and association of BQ with oral cancer, there is a need to have better awareness, prevention and interventional strategies in place. We also found considerable variation in the use of terminologies associated with BQ.

Previous studies found that ethnicity influences oral cancer patients' survival; however, most studies were limited to certain ethnic groups particularly from the West, thus of limited relevance to Asians where the disease is most prevalent. We investigated the relationship between ethnicity and patient survival in multi-racial Malaysia. 5-year survival rate was 40.9%. No statistically significant difference was observed in survival between Malays, Chinese, Indians and Indigenous peoples (45.7%, 44.0%, 41.3%, 27.7% respectively). Increased tumor size, lymph node involvement and advanced tumor were predictive of poor survival. We conclude that ethnicity has no effect on survival or its prognostic indicators.

BACKGROUND: Harassment victimization is prevalent among gay and bisexual men and may negatively impact the victims' mental health. AIMS: To examine the relationships between traditional and cyber harassment and self-identity confusion among Taiwanese gay and bisexual men in emerging adulthood. PROCEDURES: A total of 305 gay or bisexual men (age, 20-25â¯years) in Taiwan were recruited. Participants' self-identity confusion and the experiences of traditional and cyber harassment were assessed. The relationships of experiences of harassment victimization, number of places at which traditional harassment occurred, and type of harassment victimization with self-identity confusion were examined using multiple regression analysis. RESULTS: Both victims of verbal ridicule and relational exclusion and victims of physical aggression and theft of belongings had higher levels of disturbed identity and lack of identity than did non-victims. Those who experienced traditional harassment at multiple places had higher levels of unconsolidated identity and lack of identity than did those who experienced traditional harassment at only one place. Those who experienced multiple types of harassment had higher levels of unconsolidated identity than those who experienced only one type of harassment. DISCUSSIONS: Victimization of traditional harassment and multisite and multitype harassments were significantly related to self-identity confusion in gay and bisexual men.
