METHODS: We analysed sequential Global Adult Tobacco Survey (GATS) data done at least at five years interval in 10 countries namely India, Bangladesh, China, Mexico, Philippines, Russia, Turkey, Ukraine, Uruguay, and Vietnam. We estimated weighted prevalence rates of smoking behaviors namely current smoking (both daily and non-daily), prevalence of hardcore smoking (HCS) among current smokers (HCSs%) and entire surveyed population (HCSp%), quit ratios (QR), and the number of cigarettes smoked per day (CPD). We calculated absolute and relative (%) change in rates between two surveys in each country. Using aggregate data, we correlated relative change in current smoking prevalence with relative change in HCSs% and HCSp% as well as explored the relationship of MPOWER score with relative change in smoking behaviors using Spearman' rank correlation test.
RESULTS: Overall daily smoking has declined in all ten countries lead by a 23% decline in Russia. In India, Bangladesh, and Philippines HCSs% decreased as the smoking rate decreased while HCSs% increased in Turkey (66%), Vietnam (33%) and Ukraine (15%). In most countries, CPD ranged from 15 to 20 sticks except in Mexico (7.8), and India (10.4) where CPD declined by 18 and 22% respectively. MPOWER scores were moderately correlated with HCSs% in both sexes (r = 0.644, p = 0.044) and HCSp% (r = 0.632, p = 0.05) and among women only HCSs% (r = 0.804, p = 0.005) was significantly correlated with MPOWER score.
CONCLUSION: With declining smoking prevalence, HCS had also decreased and quit rates improved. Ecologically, a positive linear relationship between changes in smoking and HCS is a possible evidence against 'hardening'. Continued monitoring of the changes in quitting and hardcore smoking behaviours is required to plan cessation services.
DESIGN AND STUDY SAMPLE: Three translators were recruited to create the Albanian ESIT-SQ translation following good practice guidelines. Using this questionnaire, data from 107 patients attending otolaryngology clinics in Albania were collected.
RESULTS: Participants reporting various degrees of tinnitus symptom severity had distinct phenotypic characteristics. Application of a random forest approach on this preliminary dataset showed that self-reported hearing difficulty, and tinnitus duration, pitch and temporal manifestation were important variables for predicting tinnitus symptom severity.
CONCLUSIONS: Our study provided an Albanian translation of the ESIT-SQ and demonstrated that it is a useful tool for tinnitus profiling and subgrouping.
Methods: This study was a prospective cohort design with a historical comparison group. It was conducted to assess the difference in 30-day readmissions and mortality and to assess compliance rate with HF guideline between the historical pre-intervention audit 1 cohort and prospective post-intervention audit 2 cohorts. Audit 1 cohort were recruited from January to February 2019, whereas, audit 2 cohort which received the bundled intervention program were recruited from July to December 2019. Clinical outcomes were compared between cohorts using 30-day readmissions and mortality.
Results: A total of 50 and 164 patients were included in audit 1 and audit 2 cohort, respectively. Patients in the audit 2 cohort were younger [63.0 ± 14.5 in audit 1 vs 56.5 ± 12.7 in audit 2, p = 0.003] and majority were male [50.0% in audit 1 vs 72.0% in audit2, p = 0.004]. Thirty-day readmissions were significantly different [36.0% audit 1 vs. 22.0% audit 2, p = 0.045], but the mortality rates were similar [4.0%% audit 1 vs. 5.5% audit 2, p = 0.677] between two cohorts.
Conclusion: A significant decrease in 30-day readmissions was observed in the post-intervention audit 2 cohort in our setting. Further study in larger population and prolong study follow-up is warranted.
METHODS: In the GCD program, year-2 dental students from universities in Egypt, Hong Kong, Malaysia, UK, and the United States developed a portfolio of a restorative procedure in simulation laboratory and uploaded to an online platform (https://gcd.hku.hk/). Through the platform, the students left comments on each other's portfolios to share and discuss their knowledge and experiences on restorative dentistry. This study invited students from Hong Kong in 2018-2019 to complete an open-ended questionnaire to explore their experience on the GCD program. The feedback was compiled and analyzed.
RESULTS: All 71 year-2 students completed the questionnaire. Their most dominant comments were positive feelings about learning different clinical principles and methods from universities abroad. The students also enjoyed the cultural exchange from the comfort of their own devices. Other recurrent comments included the improvement of the skills of communication and comments on the peers' work in a professional manner. The students were enthusiastic about being able to apply their critical thinking in evaluating their work. They shared their learning barriers, including the extra time needed for the program, some unenthusiastic responses from groupmates, and delayed replies from peers. They made suggestions to remove the barriers in the learning process of the GCD program.
CONCLUSION: Students generally welcomed the GCD program and benefitted from the global academic exchange, development of critical thinking, enhancing professional communication skills, as well as opportunities of cultural exchange.
MATERIALS AND METHODS: Using CBCT imaging data, 204 mandibular first molars and 201 mandibular second molars were assessed for the interradicular and alveolar bone dimensions, tooth sizes and proximity to vital structures. The cross-sectional mandibular shape and root configuration of these molars were determined.
RESULTS: Distances to the inferior alveolar canal (IAC) from the root apices of the first molar were significantly greater than the second molar. Up to 14.5% of second molars had less than 10mm of vertical bone height between the IAC and furcation bone crest. Interradicular bone width of <3mm was found in 57% of second molars. All first molars in this study had two to three roots while 16% of second molars presented with a single root. The prevalent mandible shape at the first and second molars was the parallel and undercut ridges, respectively.
CONCLUSIONS: The mandibular second molars from samples of a Southeast Asian population presented with greater anatomical difficulties for immediate implant placement which include absent or inadequate interradicular bone thickness, higher incidence of unfavorable mandible shape and increased proximity to vital structures.
OBJECTIVE: To examine associations between weight status, body dissatisfaction and self-esteem in a sample of New Caledonian adolescents and to test for moderation effects of ethnicity on predictors of self-esteem.
METHODS: Objective anthropometric measures (height, weight, waist circumference and thickness of skinfolds) were obtained in a multi-ethnic sample of New Caledonian adolescents. Body mass index (BMI), waist-to-height ratio and the sum of four skinfolds thickness were used as proxies of weight status. Indices of ethnic identity, self-esteem, socio-demographic data (socioeconomic status, ethnicity, gender, urbanicity of residence) and body dissatisfaction were obtained using survey methods.
RESULTS: Between-group analyses indicated that adolescents of European/white origin had significantly higher self-esteem than adolescents with Oceanian Non-European Non-Asian ancestry (ONENA). However, low self-esteem was significantly associated with weight status and body dissatisfactions in European/white adolescents but not ONENA adolescents. Ethnicity moderated the relationships of predictors (BMI z-score, body dissatisfaction, age, urbanicity and ethnic identity) on self-esteem, and the strongest predictors of self-esteem were ethnicity and ethnic identity.
CONCLUSIONS: While self-esteem has important consequences for adolescent well-being and health outcomes, these results highlight the importance of applying different steps to develop and maintain healthy self-esteem in the Pacific region.
METHODS: This retrospective study included a total of 941 surgical patients who had a pre-operative home sleep study. The pre-operative CBC was extracted from the electronic patient records. Patients were stratified according to their AHI scores, into mild (AHI ≥ 5 -
METHODS: A total of 127 adults aged 18-40 years who completed clinical blood pressure assessment and echocardiography phenotyping at rest and during cardiopulmonary exercise testing, were included. Measurements were compared between participants with suboptimal blood pressure ≥120/80mm Hg (n = 68) and optimal blood pressure <120/80mm Hg (n = 59). Left ventricular systolic function during exercise was obtained from an apical four chamber view, while resting left atrial function was assessed from apical four and two chamber views.
RESULTS: Participants with suboptimal blood pressure had higher left ventricular mass (p = 0.031) and reduced mitral E velocity (p = 0.02) at rest but no other cardiac differences. During exercise, their rise in left ventricular ejection fraction was reduced (p = 0.001) and they had higher left ventricular end diastolic and systolic volumes (p = 0.001 and p = 0.001, respectively). Resting cardiac size predicted left ventricular volumes during exercise but only left atrial booster pump function predicted the left ventricular ejection fraction response ( β = .29, p = 0.011). This association persisted after adjustment for age, sex, body mass index, and mean arterial pressure.
CONCLUSION: Young adults with suboptimal blood pressure have a reduced left ventricular systolic response to exercise, which can be predicted by their left atrial booster pump function at rest. Echocardiographic measures of left atrial function may provide an early marker of functionally relevant, subclinical, cardiac remodelling in young adults with hypertension.
METHOD: Retrospective cross-sectional study, including all consecutive cases of epithelial invasive tumours, from January 2016 to December 2018. Other histological types were excluded. Univariate and multivariate analyses were performed.
RESULT: A total of 115 breast tumours were identified. Ten tumours were excluded (five ductal carcinoma in situ, four phyllodes, and one sarcoma), leaving a study population of 105 patients. Median age of presentation was 53 years (min 30; max 97). A total of 41.9% presented before the age of 50. Patients of Indigenous ethnic origins were 11 years younger at presentation than non-Indigenous women. Tumour grade was more likely to be higher among Indigenous women.
CONCLUSION: Median age of presentation of BC in Sandakan matches regional data; however, patients of Indigenous ethnic groups present even earlier. Screening guidelines should consider the growing evidence of young BC in SEA.
METHODS: We conducted an extensive search via Cochrane Library, PubMed, Scopus, and Web of Science databases to acquire the reported RCTs up to October 2020.
RESULTS: The results showed no effects of α-tocopherol supplementation on lipid profile in DM patients except when used ≥12 weeks.
CONCLUSIONS: α-tocopherol supplementation in DM patients had no significant effect on lipid profiles.
