Smoking among people living with HIV/AIDS: a bibliometric analysis (GAPRESEARCH).

Tobacco smoking undermines the effectiveness of antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA) and potentially associates with other health problems. This study aimed to analyze the growth and content of research on smoking among PLWHA on Web of Science Database. Co-occurrence analysis and Jaccard's' similarity index calculation were performed to identify and visualize networks of countries collaboration, keywords co-occurrence, and research topics. Exploratory factor analysis was applied to the abstracts' contents to uncover research domains and landscapes. The number of publications increased by 14.55% annually in the period of 1991-2017, with 74% of total papers published within 2007-2017. A wide range of topics have been covered, notably co-morbidities, interventions on smoking abstinence and cessation, and the enforcing relationship of smoking cessation with antiretroviral treatment adherence. A shortage of studies on smoking among PLWHA in low- and middle-income countries, limited collaborations between countries outside of close geographical proximity and a lack of discussion on local contexts and psychosocial factors were found. Smoking among PLWHA has been being studied more extensively in recent years, enhancing our knowledge and awareness of the significant and specific effects smoking have on PLWHA, which, in turn, assisting the proposals and implementations of suitable solutions. However, more efforts should be made to examine and understand contextualized aspects, including culture and beliefs specific to each nation or smaller sub-population within a country, especially those currently under-researched, as well as psycho-behavioral factors to implement more effective interventions to reduce smoking among PLWHA.

Brief Relaxation Practice Induces Significantly More Prefrontal Cortex Activation during Arithmetic Tasks Comparing to Viewing Greenery Images as Revealed by Functional Near-Infrared Spectroscopy (fNIRS).

BACKGROUND: There is little understanding on how brief relaxation practice and viewing greenery images would affect brain responses during cognitive tasks. In the present study, we examined the variation in brain activation of the prefrontal cortex during arithmetic tasks before and after viewing greenery images, brief relaxation practice, and control task using functional near-infrared spectroscopy (fNIRS). METHOD: This randomized controlled study examined the activation patterns of the prefrontal cortex (PFC) in three groups of research participants who were exposed to viewing greenery images (n = 10), brief relaxation practice (n = 10), and control task (n = 11). The activation pattern of the PFC was measured pre- and post-intervention using a portable fNIRS device and reported as mean total oxygenated hemoglobin (HbO µm). Primary outcome of the study is the difference in HbO µm between post- and pre-intervention readings during a cognitive task that required the research participants to perform arithmetic calculation. RESULTS: In terms of intervention-related differences, there was significant difference in average HbO µm when performing arithmetic tasks before and after brief relaxation practice (p < 0.05). There were significant increases in average HbO µm in the right frontopolar cortex (p = 0.029), the left frontopolar cortex (p = 0.01), and the left orbitofrontal cortex (p = 0.033) during arithmetic tasks after brief relaxation practice. In contrast, there were no significant differences in average HbO µm when performing arithmetic tasks before and after viewing greenery images (p > 0.05) and the control task (p > 0.05). CONCLUSION: Our preliminary findings show that brief relaxation practice but not viewing greenery images led to significant frontal lobe activation during arithmetic tasks. The present study demonstrated, for the first time, that there was an increase in activation in neuroanatomical areas including the combined effort of allocation of attentional resources, exploration, and memory performance after the brief relaxation practice. Our findings suggest the possibility that the right frontopolar cortex, the left frontopolar cortex, and the left orbitofrontal cortex may be specifically associated with the benefits of brief relaxation on the brain.

Capacity of local authority and community on epidemic response in Vietnam: Implication for COVID-19 preparedness.

Local authority's response and community adaptive capacity are critically important for the prevention and control of infectious diseases, especially for the disease with an astonishing speed of spreading like COVID-19. This study aims to examine the perception on the capability of local authority's response and community adaptation among core workforces in responding to acute events in Vietnam. Health professionals, medical students, and community workers in all regions of Vietnam were invited to participate in a web-based survey from December 2019 to February 2020. The snowball sampling technique was utilized to recruit respondents. The Tobit multivariable regression model was used to identify associated factors. The results showed that based on a 0-10 numeric rating scale, the mean scores of the capacity of local agencies and community adaptation were 6.2 ± 2 and 6.0 ± 1.8, respectively. Regarding local authority competencies, the lowest score went to "Adequate equipment, infrastructures and funding for disease prevention". For community adaptation, the respondents evaluated the capacity on "Periodic training, equipment and drills to prepare for epidemic and disaster response" competency" with the lowest mark (5.2 ± 2.5). Overall, there were significant differences in the assessment of community adaptive capacity between urban and rural areas (p < 0.01). This study indicated the moderate capacity of the local authority and community adaptation on epidemics and disasters in Vietnam. It is critically necessary to develop the action plan, response scenario and strategies to optimize the utilization of equipment and human resources in combating epidemics for each setting.

Fear of Falling among Older Patients Admitted to Hospital after Falls in Vietnam: Prevalence, Associated Factors and Correlation with Impaired Health-Related Quality of Life.

Fear of falling (FOF) diminishes older people's independence in daily activities, as well as causes serious health and economic consequences. This study examined the prevalence of FOF in older patients hospitalized due to fall-injuries, its effect on health-related quality of life (HRQOL), and its associated factors. We conducted a cross-sectional study in seven hospitals in Thai Binh, Vietnam. FOF was assessed using a single close-ended question. HRQOL was evaluated by the EQ-5D-5L instrument. Multilevel logistic regression and Tobit regression models were utilized. The prevalence of FOF in 405 older patients admitted to hospitals after fall injuries was 88.2%, with a mean EQ-5D index and EQ-VAS of 0.34 (SD = 0.38) and 61.6 (SD = 15.2), respectively. Factors associated with FOF included living alone (OR = 0.13, 95%CI = 0.04; 0.50.,), history of eye diseases (OR = 4.12; 95%CI = 1.91; 8.89), and experiencing psychological distress (OR= 3.56, 95% CI = 1.05; 12.00). After adjusting for confounders, the EQ-5D index in the FOF group reduced by 0.15 points (Coef. = -0.15; 95%CI= -0.24; -0.05) compared to that of non-FOF group. Our study shows that FOF had an independent negative relationship with HRQOL of patients. Improving knowledge about fall prevention in patients and caregivers could reduce the burden of falls in older people.

Individual and Environmental Factors Associated with Recurrent Falls in Elderly Patients Hospitalized after Falls.

Falls and recurrent falls cause great health and social consequences in older people. However, these problems are poorly understood in Vietnam. A cross-sectional study was performed at seven hospitals in Thai Binh province, Vietnam, to investigate the individual and environmental factors associated with recurrent falls among elderly patients hospitalized due to fall injuries in Vietnam. A history of recurrent falls within the last 12 months, sociodemographic, health, and clinical characteristics, as well as environmental conditions, were obtained via self-reported interviews. Multivariate logistic and Poisson regression models were used to identify associated factors. Overall, the mean fall episodes in the last 12 months were 1.8 (Standard deviation-SD = 1.2) episodes, and the 12-month prevalence of recurrent falls was 40.5%. The individual risk factors included not receiving fall prevention guidelines, walking with devices, loss of sensation in hand or foot, and using pain relief medications. The environmental risk factors comprised having too-high stairs and not having dry, clean, and nonslippery bathrooms. This study highlights a significantly high 12-month prevalence of recurrent falls in older patients hospitalized after falls in Vietnam. Moreover, regular assessments of functional disabilities and hazardous environmental conditions, as well as the provision of prevention programs, have potential to prevent falls and recurrent falls.

Patterns of Risky Sexual Behaviors and Associated Factors among Youths and Adolescents in Vietnam.

Youths and adolescents are vulnerable to HIV/STIs from unprotected sex. Promotion of young population's awareness about risky sexual behaviors is essential to develop contextualized interventions. A cross-sectional study was conducted in five Vietnamese provinces to document current attitudes and practices regarding sexual behaviors among youths. The information on sociodemographic characteristics, substance use, and sexual behaviors was collected via self-reported questionnaires. The factors associated with risky sexual behaviors were identified by the multivariate logistic regression. Among the 1200 participants, 73.5% reported having sex in their lifetime, and 48.1% used condoms at their latest sexual intercourse. Participants in urban areas were more likely not to intend to use condoms and had a higher unintended pregnancy rate than in rural areas. Older age was positively associated with not wanting to use and not using condoms. Substance-using participants were more likely to not use condoms. The participants taking alcohol or other stimulants before sex had a higher likelihood of unintended pregnancy. Respondents' attitudes and practices regarding sexual behaviors were associated with gender and employment. This study indicated that young population's awareness in Vietnam is high, however, risky sexual behaviors also remain common. Sex-related educational programs about the consequences of substance use, multiple sex partners, and unprotected sex should be developed.

Consumer Preference and Attitude Regarding Online Food Products in Hanoi, Vietnam.

This study aimed to examine: (1) how the Internet has changed consumers food-buying behavior and identify its associated factors; (2) consumers' concern about food safety information of online food products. A cross-sectional study was performed from October to December 2015 in Hanoi-a Vietnamese epicenter of food service. One thousand seven hundred and thirty six (1736) customers were randomly chosen from food establishments of 176 communes. Data were collected through face-to-face interviews using structured questionnaires. The majority of participants reported using the Internet to search for food products (81.3%). The most crucial factors influencing food purchases through the Internet were convenience (69.1%) and price (59.3%). Only one-third of participants selected products based on accurate evidence about food safety certification or food origin. The majority of participants were concerned about the expiration date (51.6%), while brand (9.8%) and food licensing information (11.3%) were often neglected. People who were:(1) female, (2) highly influenced by online relationships, and (3) having difficulty in doing usual activities were more likely to look for online food products. These findings produce practical advice to consumers when purchasing their desired food products on the Internet, to online food retailers and to the Government of Vietnam to implement appropriate legislation regarding trading online food products.

Assessing the household financial burden associated with the chronic non-communicable diseases in a rural district of Vietnam.

BACKGROUND: While there is accumulated evidence showing the rapid rise of the burden caused by non-communicable diseases (NCDs) in Vietnam, information on the extent to which households in the country suffer financial catastrophe or impoverishment caused by the diseases is still largely lacking. This paper aims to examine the self-reported prevalence of major chronic diseases among a population in rural Vietnam and to analyse the household financial burden associated with these diseases. METHODS: A cross-sectional survey of 800 randomly selected households was carried out in Vo Nhai District, Thai Nguyen Province, in 2010. Face-to-face interviews were conducted with key informants of selected households on diagnosed chronic NCDs, health care utilization and health expenditure of all household members. The World Health Organization's definitions of catastrophic expenditure and impoverishment were used. Both descriptive and analytical statistics were applied. RESULTS: The prevalence of chronic NCDs in households and individuals was 29.3 and 33.4%, respectively. The catastrophic health expenditure and impoverishment rates among the households who have at least one member with a chronic disease were 14.6 and 7.6%, respectively. These rates were significantly higher than the corresponding figures among the households whose members were free from the diseases (4.2 and 2.3%, respectively). The odds of experiencing catastrophic health expenditure and impoverishment among the household with NCD patients were 3.2 and 2.3 times greater than that of other households. CONCLUSION: Findings from this study indicate that the epidemiological and household financial burdens caused by chronic diseases in Vietnam are now substantial and need immediate mitigation measures.
