Combinations of lifestyle behaviors and cancer risk among Korean adults.

Combinations of lifestyle behaviors may lead to different cancer risks. This study aimed to identify the latent classes based on lifestyle behavior trajectories and to investigate the association between these latent classes and cancer risk. Participants in the 2002-2003 National Health Insurance Service general health examination were included.

Mortality risk according to smoking trajectories after cancer diagnosis among Korean male cancer survivors: A population-based cohort study.

Introduction: Previous research on post-diagnosis smoking among cancer survivors mainly relied on smoking status, which may not fully reflect the impact of changes in smoking levels. This study aimed to evaluate mortality risk according to smoking trajectories among Korean male cancer survivors, using a trajectory approach to comprehensively capture smoking patterns.

Methods: The study included 110555 men diagnosed with cancer between 2002 and 2018 from the Korean National Health Information Database.

Smoking Cessation, Quit Attempts and Predictive Factors among Vietnamese Adults in 2020.

Objective: This study aims to describe the updated smoking cessation and quit attempt rates and associated factors among Vietnamese adults in 2020.

Methods: Data on tobacco use among adults in Vietnam in 2020 was derived from the Provincial Global Adult Tobacco Survey. The participants in the study were people aged 15 and older.

Trajectory of physical activity frequency and cancer risk: Findings from a population-based cohort study.

Background: Physical activity (PA) changes throughout an individual's life, but the association between such changes and cancer risk seems to be overlooked in the literature. Thus, this study aimed to examine the association between the trajectories of PA frequency and cancer incidence among middle-aged Korean adults.

Methods: A total of 1,476,335 eligible participants (992,151 men and 484,184 women) aged ≥40 years from the National Health Insurance Service cohort (2002-2018) were included.

Estimation of the Acoustic Transducer Beam Aperture by Using the Geometric Backscattering Model for Side-Scan Sonar Systems.

In this paper, we propose an algorithm for estimating the beam aperture of the acoustic transducers by using the geometric backscattering model for side-scan sonar systems. The geometric backscattering model is developed to describe the propagation paths of the signal transmitted from the transducers towards the seabed and backscatters to the hydrophones. To evaluate our proposed algorithm, we have developed a side-scan sonar system.

Alcoholic liver disease in relation to cancer incidence and mortality: Findings from a large, matched cohort study in South Korea.

Aim: To estimate the risk of cancer incidence and mortality among patients with alcoholic liver disease in South Korea.

Methods: A matched cohort study was conducted, including 1,042,185 men (alcoholic liver disease cases: 208,437; controls: 833,748) and 100,400 women (alcoholic liver disease cases: 20,080; controls: 80,320), matched for sex, age, smoking, alcohol consumption, and body mass index at a 1:4 ratio. The risk of cancer incidence and mortality in the alcoholic liver disease group was assessed using Cox proportional hazards regression models.

Cancer Risk According to Alcohol Consumption Trajectories: A Population-based Cohort Study of 2.8 Million Korean Men.

Background: Alcohol drinking behaviors change temporally and can lead to changes in related cancer risks; previous studies have been unable to identify the association between the two using a single-measurement approach. Thus, this study aimed to investigate the association of drinking trajectories with the cancer risk in Korean men.

Methods: A trajectory analysis using group-based trajectory modeling was performed on 2,839,332 men using data on alcohol drinking levels collected thrice during the Korean National Health Insurance Service's general health screening program conducted between 2002 and 2007.

Exposure to Electronic Cigarette Advertisements and Use of Electronic Cigarettes: A Meta-analysis of Prospective Studies.

Introduction: Electronic cigarette (EC) advertisements remain unregulated and approach consumers in TV commercials, print ads, radio, and other forms of digital marketing.

Aims And Methods: This study aimed to assess whether exposure to EC advertisements is associated with the use of EC by using a meta-analysis of prospective studies. We searched PubMed, EMBASE, and Web of Science to locate eligible studies in November 2021.

Weight-change trajectory in relation to cancer risk: findings from a nationwide cohort study in South Korea.

Objective: This study examined relationships between weight-change trajectories and all cancers and obesity-related cancer risks.

Methods: A total of 1,882,304 men and 899,912 women from the 2002 to 2017 National Health Insurance Service cohort were included. Weight-change trajectories in 2002 to 2009, according to BMI, were determined using group-based trajectory modeling.

Progression of liver fibrosis and associated factors among chronic hepatitis B patients at a general hospital in Northern Vietnam.

Evaluation of liver fibrosis is necessary to make the therapeutic decision and assess the prognosis of CHB patients. The current study aimed to describe the progression and identify some influencing factors in patients with chronic hepatitis B at a General Hospital in Northern Vietnam. The longitudinal study included 55 eligible subjects diagnosed Hepatitis-B-virus.

Multilevel Analysis of 24-Hour Blood Pressure, Heart Rate, and Associated Factors among Police Officers in Hanoi, Vietnam.

Background: Due to long-hour outdoor working environment, policemen have been subjected to tremendous health risks including blood pressure (BP) and heart rate (HR). In tropical countries, the temperature is extremely harsh which may get peak at above 40 Celsius degrees or drops under 8 Celsius degrees. However, the existing data on the effects of weather variation on BP and HR among police task force has been scarce in Vietnam.

Factors associated with the duration of hospitalisation among COVID-19 patients in Vietnam: A survival analysis.

Background: The median duration of hospital stays due to COVID-19 has been reported in several studies on China as 10-13 days. Global studies have indicated that the length of hospitalisation depends on different factors, such as the time elapsed from exposure to symptom onset, and from symptom onset to hospital admission, as well as specificities of the country under study. The goal of this paper is to identify factors associated with the median duration of hospital stays of COVID-19 patients during the second COVID-19 wave that hit Vietnam from 5 March to 8 April 2020.

Influence of new tobacco control policies and campaigns on Quitline call volume in Korea.

Introduction: While tobacco control policies have been adopted and enforced, and anti-smoking campaigns have been conducted, the evaluation of their impact on tobacco quitting is lacking in Korea. Therefore, the effectiveness of tobacco control policies and mass media campaigns to encourage use of the Quitline were evaluated by monitoring call volume on Quitline, which has been in operation since 2006, in Korea.

Methods: Tobacco control policies and mass media campaigns, from 1 January of 2007 to 31 December of 2016, were assessed from the review of government documents and the history of law and regulation changes.

Knowledge, Attitude, and Practice Regarding Breast Cancer Early Detection Among Women in a Mountainous Area in Northern Vietnam.

Breast cancer is the most common cancer in women all over the world, also in Vietnam. In recent years, the incidence of breast cancer has been increasing in Vietnam, and most cases are diagnosed at late stages, making treatment more difficult. More and better early detection could help more women to survive.

Adherence to Antiplatelet Therapy after Coronary Intervention among Patients with Myocardial Infarction Attending Vietnam National Heart Institute.

Adherence to antiplatelet therapy is critical to successful treatment of cardiovascular conditions. However, little has been known about this issue in the context of constrained resources such as in Vietnam. The objective of this study was to examine the adherence to antiplatelet therapy among patients receiving acute myocardial infarction interventions and its associated factors.
