Tobacco consumption, as a worldwide problem, is a risk factor for several types of cancer. In Vietnam, tobacco consumption in the form of waterpipe tobacco smoking is common. This prospective cohort study aimed to study the association between waterpipe tobacco smoking and gastric cancer mortality in Northern Vietnam. A total of 25,619 eligible participants were followed up between 2008 and 2019. Waterpipe tobacco and cigarette smoking data were collected; semi-quantitative food frequency and lifestyle questionnaires were also utilized. Gastric cancer mortality was determined via medical records available at the state health facilities. A Cox proportional hazards model was used to estimate hazard ratios (HR) and 95% confdence intervals (95% CI). During 314,992.8 person-years of followup, 55 men and 25 women deaths due to gastric cancer were identifed. With never-smokers as the reference, the risk of gastric cancer mortality was signifcantly increased in participants who were ever-smoking (HR=2.43, 95% CI=1.35–4.36). The positive risk was also observed in men but was not signifcantly increased in women. By types of tobacco use, exclusive waterpipe smokers showed a signifcantly increased risk of gastric cancer mortality (HR=3.22, 95% CI=1.67–6.21) but that was not signifcantly increased in exclusive cigarette smokers (HR=1.90, 95% CI=0.88– 4.07). There was a signifcant positive association between tobacco smoking and gastric cancer death for indicators of longer smoking duration, higher frequency per day, and cumulative frequency of both waterpipe and cigarette smoking. Waterpipe tobacco smoking would signifcantly increase the risk of gastric cancer mortality in the Vietnamese population. Further studies are required to understand the waterpipe tobacco smoking-driven gastric cancer burden and promote necessary interventions.

Background Trends in the public perception and awareness of COVID-19 over time are poorly understood. We conducted a longitudinal study to analyze characteristics and trends of online information during a major COVID-19 outbreak in Da Nang province, Vietnam in July-August 2020 to understand public awareness and perceptions during an epidemic. Methods We collected online information on COVID-19 incidence and mortality from online platforms in Vietnam between 1 July and 15 September, 2020, and assessed their trends over time against the epidemic curve. We explored the associations between engagement, sentiment polarity, and other characteristics of online information with different outbreak phases using Poisson regression and multinomial logistic regression analysis. We assessed the frequency of keywords over time, and conducted a semantic analysis of keywords using word segmentation Results
We found a close association between collected online information and the evolution of the
COVID-19 situation in Vietnam. Online information generated higher engagements during
compared to before the outbreak. There was a close relationship between sentiment polarity
and posts’ topics: the emotional tendencies about COVID-19 mortality were significantly
more negative, and more neutral or positive about COVID-19 incidence. Online newspaper
reported significantly more information in negative or positive sentiment than online forums
or social media. Most topics of public concern followed closely the progression of the
COVID-19 situation during the outbreak: development of the global pandemic and vaccination; the unfolding outbreak in Vietnam; and the subsiding of the outbreak after two months.
Conclusion
This study shows how online information can reflect a public health threat in real time, and
provides important insights about public awareness and perception during different outbreak
phases. Our findings can help public health decision makers in Vietnam and other low and
middle income countries with high internet penetration rates to design more effective communication strategies during critical phases of an epidemic
Cancer Epidemiology
Background: Survival for Primary Liver Cancer (PLC) has been investigated in Australia, but limited work has been conducted on the burden for people with different socioeconomic status, region of residence, causes of PLC, and culturally and linguistically diverse (CALD) backgrounds. This study aimed to cover this gap in the literature by investigating PLC survival with the aforementioned factors. Methods: This study linked four administrative datasets: Victorian Cancer Registry, Admitted Episodes Dataset, Emergency Minimum Dataset, and Death Index. The cohort was all cases with a PLC notification within the Victorian Cancer Registry between 01/01/2008 and 01/01/2016. The Kaplan-Meier method was used to estimate survival probabilities and the log-rank test was used to compare the difference in survival between subgroups. The Cox proportional hazard model was used to explore factors associated with PLC survival. Results: The 1-, 3- and 5-year survival rates were 50.0%, 28.1% and 20.6%, respectively, with a median survival of 12.0 months (95% confidence interval (CI): 11.0 – 12.9 months). Higher survival was associated with younger age, hepatocellular carcinoma, and higher socio-economic status. People born in Asian, African, and American regions had higher survival than those born in Australia and New Zealand. Cases with viral hepatitis as an identified aetiology had higher survival than those whose PLC was related to alcohol consumption (hazard ratio=1.52, 95% CI: 1.19 – 1.96), diabetes and fatty liver disease (hazard ratio=1.35, 95% CI: 1.08 – 1.68). Conclusion: Survival outcomes for people diagnosed with PLC were still poor and affected by many factors. Asian and African cases had better survival than Australian and New Zealand patients as PLC in Asian and African cases was mostly caused by viral hepatitis. Metropolitan areas were associated with a higher survival than rural areas, not only due to accessibility to surveillance and healthcare services but also because the majority of overseasborn patients reside in metropolitan areas.
Objective The goal of this study was to describe the burden of disease and in-hospital mortality among patients admitted to the critical care units (CCUs) in Vietnam. Design Retrospective study. Setting The whole 1-year data of admissions to CCUs were collected from 34 hospitals from January to December 2018. Participants A total of 44 013 episodes of admission to CCUs were analysed. Primary outcome We used International Classification of Diseases-11 codes to assess the primary diagnosis associated with admissions and in-hospitals mortality. Years of life lost (YLL) measure was further used to estimate the burden of disease. Results The 0–5 years and ≥70 years age groups accounted for 14.8% (6508/44 013) and 26.1% (11 480/44 013) of all admissions, respectively. The most common diagnoses were diseases of the respiratory system (27.8% or 12 255/44 013), followed by unclassified symptoms, signs or clinical findings (13% or 5712/44 013), and diseases of the circulatory system (12.2% or 5380/44 013). Among 28 311 patients with available outcome data, 1681 individuals (5.9%) died during the hospitalisation. The in-hospital mortality rate increased with age, from 2.8% (86/3105) in under 5 years old age group to 23.1% (297/1288) in over 90-year age group. Diseases of the respiratory system was the leading causes of death in term of number of deaths (21.8% or 367/1681 of all deaths). Diagnosis of sepsis was associated with the highest in-hospital mortality (36.8%). The overall YLL under the age of 75 were 1287 per 1000 patients. Conclusions CCUs in Vietnam faced wide differences in the burden of diseases. Sufficient infrastructure and adequate multidisciplinary training are essential to ensure the appropriate response to the current needs of population.

Non - communicable diseases (NCDs) are the leading causes of death and disability globally. In Vietnam, NCDs account for 77% of all deaths. The purpose of this systematic review is to describe the patterns of mortality associated with NCDs in Vietnam from 2006 to 2016. We included 25 studies that reported on health impacts especially on mortality NCDs in Vietnam. From 2008 to 2012, NCDs deaths decreased by 2% (75% vs 73%) and from 2012 to 2016, it increased by 4% (73% vs 77%). The probability of premature deaths of NCDs in 2010, 2012 and 2016 were at 17.5%, 17.4% and 17.0%, respectively. Though the mortality patterns seem to decline over the years, it is not significant enough to conclude, and the probability of dying prematurely is still very high in the country. The percentage of deaths for male was 26.4% (2008), 54.3% (2012), 23.0% (2016) higher than those for female 19.4% (2008), 30.0% (2012), 11.0% (2016). Worldwide, 41 millions people die from non-communicable diseases each year with 15 millions people die between 30 - 69. Cardiovascular diseases remained the main leading cause of NCDs deaths, cancer was the second leading cause of NCDs deaths and projected to increase further in subsequent reports.
