Abstract
INTRODUCTION Internet addiction has been a major behavioral disorder over the past decade. Prior meta-analytic review has demonstrated the association between Internet addiction and psychiatric disorders, as well as sleep related disorders. AIMS AND OBJECTIVES There remains a paucity of literature about Internet addiction and sleep related disorders in low and middle income countries like Vietnam. It is the aim of this exploratory study to determine the association. METHODOLOGY An online cross-sectional study was conducted between August through to October 2015. Respondent drive sampling technique was utilized in the recruitment of participants. The short form version of the Young's Internet addiction test was administered and sleep related disorders was ascertained by means of a self-report questionnaire. Chi-squared, t-test and ANOVA were used to determine whether there were any significant differences amongst the variables considered. Multivariate logistic regressions were also used in the analysis, in order to identify factors associated with Internet addiction. RESULTS 21.2% Of the participants were diagnosed with Internet addiction. 26.7% of those with Internet addiction also reported that they have had sleep related difficulties. 77.2% of these participants were receptive towards seeking medical treatment. Our current study also highlighted that being single and those who were using tobacco products were not at heightened risk of developing associated sleep related issues. CONCLUSIONS Our current study is largely a cross-sectional exploratory study that has shown that there is a significant prevalence of both Internet addiction and sleep related disorders amongst Vietnamese youth.

Abstract
OBJECTIVES The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online. METHODS An online cross-sectional study was conducted with 1,080 Vietnamese youths. A standardized questionnaire was used. Respondent-driven sampling was applied to recruit participants. Multivariate logistic and Tobit regressions were utilized to identify the associated factors. RESULTS About 59.5% of the males and 12.7% of the total youths declared that they were actively using alcohol. From the total sample, a cumulative total of 32.3% of the participants were drinking alcohol, with 21.8% and 25.0% of the participants being classified as drinking hazardously and binge drinkers, respectively. The majority of the participants (60.7%) were in the pre-contemplative stage. CONCLUSIONS A high prevalence of hazardous drinking was recognized among online Vietnamese youths. In addition, we found relationships between alcohol use disorder and other addictive disorders, such as tobacco smoking and water-pipe usage. Our results highlighted that the majority of the individuals are not receptive to the idea of changing their alcohol habits, and this would imply that there ought to be more government effort towards the implementation of effective alcohol control policies.

Abstract
Background Internet addiction (IA) is a common problem found in young Asians. This study aimed to study the influence of IA and online activities on health-related quality of life (HRQOL) in young Vietnamese. This study also compared the frequencies of anxiety, depression and other addiction of young Vietnamese with and without IA. Methods This study recruited 566 young Vietnamese (56.7% female, 43.3% male) ranging from 15 to 25 years of age via the respondent-driven sampling technique. Chi-squared, t-test and analysis of variance were used to compare young Vietnamese with and without IA. Regression analyses were used to examine the association between internet usage characteristics and HRQOL. Results Results from this cross-sectional study showed that 21.2% of participants suffered from IA. Online relationship demonstrated significantly higher influences on behaviors and lifestyles in participants with IA than those without IA. Participants with IA were more likely to have problems with self-care, difficulty in performing daily routine, suffer from pain and discomfort, anxiety and depression. Contrary to previous studies, we found that there were no differences in gender, sociodemographic, the number of participants with cigarette smoking, water-pipe smoking and alcohol dependence between the IA and non-IA groups. IA was significantly associated with poor HRQOL in young Vietnamese. Conclusion IA is a common problem among young Vietnamese and the prevalence of IA is the highest as compared to other Asian countries. Our findings suggest that gender may not play a key role in IA. This can be an emerging trend when both genders have equal access to the internet. By studying the impact of IA on HRQOL, healthcare professionals can design effective intervention to alleviate the negative consequences of IA in Vietnam.

Abstract
To investigate the influence of cation mobility variation due to the mixed glass former effect, 0.45Li(2)O-(0.55-x)P(2)O(5)-xB(2)O(3) glasses (0≤x≤0.55) are studied keeping the molar ratio of Li(2)O/(P(2)O(5)+B(2)O(3)) constant. Addition of B(2)O(3) into lithium phosphate glasses increases the glass transition temperature (T(g)) and number density, decreases the molar volume, and generally renders the glasses more fragile. The glass system has been characterised experimentally by XRD, XPS and impedance studies and studied computationally by constant volume molecular dynamics (MD) simulations and bond valence (BV) method to identify the structural variation with increasing the B(2)O(3) content, its consequence for Li(+) ion mobility, as well as the distribution of bridging and non-bridging oxygen atoms. These studies indicate the increase of P-O-B bonds (up to Y=[B(2)O(3)]/([B(2)O(3)]+[P(2)O(5)])≈0.5 and B-O-B bonds, as well as the decrease of P-O-P bonds and non-bridging oxygens (NBOs) with rising B(2)O(3) content. The system with Y≈0.5 exhibits maximum ionic conductivity, 1.0×10(-7) S cm(-1), with activation energy 0.63 V. Findings are rationalised by a model of structure evolution with varying B(2)O(3) content Y and an empirical model quantifying the effect of the various structural building blocks on the ionic conductivity in this mixed glass former system.

Abstract
OBJECTIVE To examine the relationship between hypertension, overweight and indices of insulin resistance in Vietnamese subjects. PATIENTS One hundred and eight hypertensive subjects (51 men and 57 women) over 40 y of age were compared with 36 control subjects over 40 y of age. METHODS Blood glucose and plasma insulin were measured at fasting and 2 h after 75 g glucose taken orally. RESULTS Hypertensive subjects had significantly higher body mass index (BMI), triceps skinfold, waist and hip circumferences and waist/hip ratio. Glycaemia at fasting and after glucose were similar in the two groups. Insulinaemia at fasting and after glucose were significantly higher in the hypertensive subjects. In the whole series of hypertensive subjects, plasma insulin and insulin/glucose ratio at fasting and after glucose correlated significantly with BMI, triceps skinfold and waist and hip cicumferences. After exclusion of the subjects with BMI > 22 kg/m2, compared with the controls, plasma insulin and insulin/glucose ratio were significantly higher in the whole hypertensive group and separately in hypertensive men and women. The logistic regression analyses have shown that plasma insulin and insulin/glucose ratio at fasting and after glucose were significantly associated with hypertension, independently of gender, BMI and waist circumference. CONCLUSION This study shows that in Vietnamese people, essential hypertension is associated with a significant increase in BMI, which however remains far lower than the definition threshold of occidental obesity and with a state of insulin resistance found despite very slight or no excess weight.

Abstract
Several epidemiological and experimental studies suggest that essential arterial hypertension is associated with hyperinsulinism and insulin resistance in obese subjects and also in subjects with normal body weight. Undernutrition remains frequent in adult Vietnamese people and mean body mass index is around 18.5 kg/m2 in Vietnam. The aim of this study was to look for insulin resistance in hypertensive Vietnamese subjects, despite a markedly lower BMI in Vietnam than in occidental countries. One hundred and eight hypertensive patients (51 men and 57 women) over 40 years (mean = 65.4 years) were compared with 36 healthy subjects (23 men and 13 women) over 40 years (mean = 63.8 years). Hypertensive patients had significantly higher BMI (20.5 +/- 0.3 (SEM) kg/m2 vs 18.4 +/- 0.4 kg/m2; p < 0.01), thicker triceps skinfold (1.26 +/- 0.07 cm vs 0.71 +/- 0.07 cm; p < 0.001) and not significantly different waist/hip ratio (0.88 +/- 0.01 vs 0.85 +/- 0.01). Blood glucose at fasting and 2 hours after 75 g glucose taken orally were similar in hypertensive and normotensive subjects. Plasma insulin at fasting and 2 hours after glucose were significantly higher in hypertensive patients (44.4 +/- 5.1 pmol/L vs 21.6 +/- 3.2 pmol/L; p < 0.05 and 271.1 +/- 21.6 pmol/L vs 139.1 +/- 15.2 pmol/L; p < 0.001). Thus, despite under-nutrition, hypertensive Vietnamese patients have a moderate but significant increase in BMI and fat mass without predominant abdominal localization, and a state of insulin-resistance, compared with normotensive healthy subjects.
