RESUMEN
BACKGROUND: Traumatic brain injury (TBI) is a leading cause of mortality and morbidity globally. This study aimed to measure the health-related quality of life (HRQOL) of TBI patients in Vietnam and evaluate the associated factors. METHODS: A longitudinal study was conducted in Thai Binh, Vietnam, from February to September 2020. The EuroQol-5 Dimensions-5 Levels (EQ-5D-5L) and EQ-Visual Analog Scale (EQ-VAS) were used to measure HRQOL. Socio-demographic characteristics, including age, gender, education level, employment status, marital status, and income, as well as clinical characteristics such as injury severity, cause of injury, comorbidities, and functional status, were collected through patient interviews and medical records. Multivariate Tobit regression analysis was performed to identify variables associated with HRQOL. RESULTS: The study included 212 TBI patients. The mean scores of the VAS and EQ-5D-5L scales were 82.4/100 (SD = 14.49) and 0.9/1.0 (SD = 0.2), respectively, indicating a relatively high HRQOL. However, certain factors significantly impacted HRQOL. Unemployed patients and those with depression or higher injury severity, as measured by the Injury Severity Score (ISS), had notably lower HRQOL scores. Poor sleep quality and severe functional impairments also adversely affected HRQOL, whereas patients discharged for a longer period had slightly better HRQOL scores. CONCLUSION: This study highlights that while HRQOL is relatively high among TBI patients, mental health disorders, injury severity, and functional impairments are key factors negatively impacting their quality of life. High HRQOL was defined by mean scores on the VAS and EQ-5D-5L scales, with higher scores indicating better quality of life. Home-based interventions addressing these issues could improve HRQOL for TBI patients.

The objective of this study was to create a plant-based drink from jackfruit seed. Firstly, jackfruit seed powder was hydrolyzed step by step with 0.2% α-amylase for 60 min and 0.3% glucoamylase for 90 min. The sample then was fermented with Lactiplantibacillus plantarum (L. plantarum) at 37 °C for 15 h. The findings indicated that hydrolysis and lactic acid fermentation enhanced the polyphenol, flavonoid, and antioxidant activity of jackfruit seed drink. Jackfruit seed drink was a favorable matrix for L. plantarum delivery. Moreover, the product underwent fermentation and reached the viability density of L. plantarum of 8.15 Log CFU/mL. The overall sensory liking score was rated between 5 and 5.5/7 points. Throughout the 35 days of storage period at 4-6 °C, the number of L. plantarum uncharged, whereas the bioactive compound and antioxidant activity of the product diminished by nearly 20-50% compared to the sample before storage. Overall, this research highlights the potential of the the fermented jackfruit seed drink as a probiotic plant-based drink with massive biological function and sensory appeal.
RESUMEN
OBJECTIVE: The prevention of HIV/AIDS is not making sufficient progress. The slow reduction of HIV/AIDS infections needs to prioritise hesitancy towards service utilisation, including treatment duration, social support and social stigma. This study investigates HIV-positive patients' avoidance of healthcare services and its correlates. DESIGN: A cross-sectional study. SETTING: The secondary data analysis used cross-sectional data from a randomised controlled intervention, examining the effectiveness of HIV-assisted smartphone applications in the treatment of HIV/AIDS patients in the Bach Mai and Ha Dong clinics in Hanoi. METHODS: Simple random sampling was used to identify 495 eligible patients. Two-tailed χ2, Mann-Whitney, multivariate logistic and ordered logistic regression models were performed. PRIMARY AND SECONDARY OUTCOME MEASURES: The main study outcome was the patients' healthcare avoidance and frequency of healthcare avoidance. The association of individual characteristics, social and behavioural determinants of HIV patients' usage of health services was also determined based on the collected data using structured questionnaires. RESULTS: Nearly half of the participants avoid health service use (47.3%), while 30.7% rarely avoid health service use. Duration of antiretroviral therapy and initial CD4 cell count were negatively associated with avoidance of health services and frequency of health service avoidance. Similarly, those with the middle and highest income were more likely to avoid health services compared with those with the lowest income. People having health problems avoided health service use more frequently (OR 1.47, 95% CI 1.35 to 1.61). CONCLUSIONS: Our study's findings identify characteristics of significance in relation to health service avoidance and utilisation among HIV-positive patients. The results highlighted the need to improve satisfaction, adherence and utilisation of treatment. Moreover, identifying ways to address or incorporate those social determinants in new policy may also help the treatment of HIV/AIDS and strategically allocate funding in the changing financial and political climate of Vietnam. TRIAL REGISTRATION NUMBER: Thai Clinical Trials Registry TCTR20220928003.

PURPOSE: The COVID-19 pandemic has transformed the way of life of many individuals, especially those working at the frontlines, such as healthcare workers. Our study aims to examine the impact of COVID-19 on the socio-economic status, quality of life, and sleep quality when Vietnam was experiencing the 4th wave of the COVID-19 pandemic. METHODS: A cross-sectional study was conducted on 604 healthcare workers using snowball sampling from October through to November 2021. Our study examined the impact of the government's COVID-19 prevention policy including personal protective measures (5K measures), directive 15, directive 16, and directive 16 plus. The EQ-5D-5L and EQ-VAS were used to measure health-related quality of life and a scale of 1 to 10 was used to rate sleep quality of healthcare workers. RESULTS: A total of 604 respondents, most people were female (57.9%), and working as civil servants (75.3%). Very few participants were able to increase their earnings during the pandemic. Participants who did not have monthly allowance amounts had the highest proportion (60.1%), followed by those under 2 million VND (21.2%). In the univariate regression model, people with high government policy scores tend to have lower quality of life and sleep quality scores. In addition, in the multivariable regression model, people with high scores on government policies tend to have lower quality of life (EQ-5D) scores. CONCLUSION: The COVID-19 prevention measures had a negative impact on quality of life, sleep quality, and daily demands of healthcare workers. These findings should help guide future policy implementations.

Background: Self-medication is recognized as an effective form of treatment and is increasingly encouraged to treat minor illnesses. However, misuse of self-medication leaves devastating impacts on human health and causes antimicrobial resistance. Using medication without a prescription among farmers could cause more severe effects on their health than non-farm workers since they suffer from several occupational hazards such as excessive exposure to pesticides. Methods: A cross-sectional study was conducted in 197 residents living in Moc Chau from August to September. A structured questionnaire and face-to-face were used to collecting data. The multivariate logistic model was applied to indicate associated factors with the self-medication. Results: The prevalence of self-medication among farmers was 67%. Pain relievers (66.7%) and antibiotics (32.5%) were the types of medicines that were the most commonly purchased and used without a medical prescription. Ethnics and health status also significantly affected the self-medication practice as well as the purchase and use of antibiotics. The distance to travel to a medical center and the dangerous or difficult travel, participants with arthritis or inpatient treatment had significantly associated with buying and using the medicine and antibiotics without the medical prescription of farmers. Conclusion: Our research highlights a considerably high prevalence of self-medication among farmers residing in the mountainous area of Vietnam. Individual factors such as ethnics, health status, distance to health centers, and dangerous or difficult travel were found to be related to the SM practice as well as the purchase and use of antibiotics. From that, the current study suggests interventions. For instance, official guidelines are needed to raise awareness and minimize the disadvantages of self-medication; and digital health technologies should be applied to reduce the gap in healthcare service between mountainous and other areas of Vietnam.

Alcohol drinking has long been reported to be common in people living with HIV/AIDS, having biological and behavioral impacts on the transmission, progression, and prevention of HIV/AIDS. A total of 7059 eligible articles and reviews published in English from 1990 to 2019 were extracted from the WOS. Results show an increase in publication volume, while citations peak for papers published in 2006. Content analysis reveals a wide-ranging coverage of topics, with the most popular being effects of alcohol consumption on ART adherence and outcomes, alcohol-related sexual behaviors, TB co-infection, and psycho-socio-cultural considerations in examining and designing measures targeting alcohol use and interventions to reduce alcohol dependence in PLWHA. This calls for more active engagement of governments in research and in designing and implementing interventions, as well as collaborations and knowledge transfer from high-income countries to developing counterparts, to effectively address alcohol use-related issues in PLWHA, moving toward the HIV/AIDS eradication target.
RESUMEN
Mitigating the impacts of Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) and substance use requires comprehensive and systematic thinking in designing interventions and developing policies. This study describes the growth of research publications from 1991 to 2021 in the Web of Science database and points out current research landscapes in the fields of HIV/AIDS and substance use. Latent Dirichlet Allocation was used for classifying 21 359 papers into corresponding topics. The most common topics were HIV transmission, HIV infection, quality of life and mental health of substance users, and the biomedical effect of substance use. Emerging research landscapes include vulnerabilities of people who inject drugs to HIV transmission and related health problems. This study found a lack of research on health services, interdisciplinary and inter-sectoral in combination with clinical evaluation and treatment services. Future investment and implementation of HIV/AIDS and substance use programs should focus on research of health services and clinical evaluation, especially context-specific interventions.
RESUMEN
CLINICAL RELEVANCE: Myopia prevention and anti-myopia treatment is of great importance in South East Asia. BACKGROUND: To evaluate the prevalence and related factors of myopic retinopathy in Vietnam. METHODS: A cross-sectional study was conducted on 168 eyes of 88 patients with high myopia presenting to the Refraction Department of Vietnam National Eye Hospital. Inclusion criteria were high myopia (≤-6.00D with cycloplegic retinoscopy). Consecutive presenting patients recruited between January 2020 and August 2020 consented to participate. RESULTS: Participant age range was 12-47 years. Peripapillary atrophy was present in 70.2% of participants, most commonly atrophy of one-quarter of the disc (38.7%). Central retinal changes were present in 66.1% of participants, subclassified as tessellated fundus in 60.7%, diffuse chorioretinal atrophy in 4.2% and patchy chorioretinal atrophy in 1.2%. Peripheral retinal lesions were present in 43.5% of participants, consisting of white-without-pressure in 32.1%, lattice degeneration in 16.1%, snail track degeneration in 4.2% and microcystoid degeneration in 1.2%. Myopia ≤-8.00D and axial length ≥26.5 mm were associated with additional risk of posterior ocular complications. Furthermore, age ≥19 years increased risk of central myopic retinopathy and ≥10 years since initial myopia diagnosis increased the risk of peripapillary atrophy and central retinal changes. Other factors such as the age of onset of myopia and family myopia history did not appear to alter the risk of peripheral retina damage. CONCLUSIONS: Retinal disorders were common in Vietnamese people with high myopia. Within the current cohort with high myopia, myopia ≤-8.00D and axial length ≥26.5 mm were associated with a significant further elevation of risk.

Introduction: Although the pathogenesis of depressive disorders is not fully elucidated, untreated adolescent depression can lead to serious sequelae such as impaired academic performance and social functioning, substance use disorders, poor self-esteem, and increased risk for suicidal ideation and attempts. Literature on adolescent mental health in Vietnam is limited, despite increased international awareness of this critical issue. This study aimed to investigate the prevalence and associations of depressive symptoms in Vietnamese adolescents. Methods: A cross-sectional, self-administered survey was conducted in five provinces of Vietnam among adolescents aged 14 to 24 years. In addition to collecting participants' demographics, a structured questionnaire was developed to examine depressive symptoms, suicidal ideation, loneliness, and cyberbullying victimization. Depressive symptoms and loneliness were assessed via the PHQ-9 and UCLA Loneliness Scale, respectively. Two-tailed Chi-squared, Mann-Whitney, and Kruskal-Wallis tests were performed to examine associations between variables. Multivariate Logistic regression models were conducted to examine the associations between prior-defined variables and positive depressive symptoms. Results: Among 1,600 respondents, 31.8% of participants reported having mild-moderate or severe depressive symptoms. Participants within the moderate-severe depressive symptom group had significantly lower community cohesion scores than those of participants in normal and mild depressive symptom groups (p < 0.05). Youths living alone were more likely to have moderate-severe depressive symptoms (OR 2.16; 95% CI: 1.09-4.25). Cyberbullying had significant associations with depressive severity (OR 1.93; 95% CI 1.38-2.70). Conclusion: The findings of this study characterize various risk and protective factors for depression in Vietnamese youths and adolescents. The results highlight the importance of raising awareness and increasing access to educational resources for depression and other mental health illnesses. With the rising prevalence of depression, parents, teachers, and community leaders play a vital role in addressing mental health problems in adolescents.

Social networks (SN) shape HIV risk behaviors and transmission. This study was performed to quantify research development, patterns, and trends in the use of SN in the field of HIV/AIDS, and used Global publications extracted from the Web of Science Core Collection database. Networks of countries, research disciplines, and most frequently used terms were visualized. The Latent Dirichlet Allocation method was used for topic modeling. A linear regression model was utilized to identify the trend of research development. During the period 1991-2019, in a total of 5,698 publications, topics with the highest volume of publications consisted of (1) mental disorders (16.1%); (2) HIV/sexually transmitted infections prevalence in key populations (9.9%); and (3) HIV-related stigma (9.3%). Discrepancies in the geographical distribution of publications were also observed. This study highlighted (1) the rapid growth of publications on a wide range of topics regarding SN in the field of HIV/AIDS, and (2) the importance of SN in HIV prevention, treatment, and care. The findings of this study suggest the need for interventions using SN and the improvement of research capacity via regional collaborations to reduce the HIV burden in low- and middle-income countries.

Introduction: Tetanus vaccine coverage in Vietnam has been declining in recent years due to a rapid population growth rate, shrinking budget, and inefficient resource mobilization strategy. This study examined the uptake, demand, and willingness to pay (WTP) for tetanus vaccines in Vietnamese women of reproductive age as well as determined associated factors and assessed the feasibility of the long-term tetanus vaccine resource mobilization scheme. Methods: Cross-sectional data were obtained on 807 women of childbearing age in Hanoi, Vietnam in 2016. Tetanus vaccine uptake, demand, and willingness to pay were collected by using a structured questionnaire. Multivariable logistic and interval regression models were used to examine associated factors with vaccine uptake, demand, and WTP. Results: Of 807 participants, 42.4 and 64.8% had sufficient tetanus vaccination (i.e., received at least three doses of vaccine) and were willing to pay for tetanus vaccination. The mean amount of WTP for one dose of tetanus was US$ 7.3 (95% CI = 6.7-7.9). Having children or being aware that the tetanus vaccine was free-of-charge were negatively associated with WTP for tetanus vaccine. Having a high school education, living in a rural area, and not being aware of vaccine prices or being aware that vaccines were provided freely reduced the amount of WTP. WTP increased among women receiving information from friends and relatives. Conclusion: Despite of exemption from the tetanus vaccination programs, this study indicated a low tetanus vaccination coverage and a moderate degree of WTP for tetanus vaccine among Vietnamese women of childbearing age. Target-specific educational and financial support interventions, along with efforts to reduce vaccination costs are critical to improving the vaccine uptake, demand, and WTP for tetanus immunization among women.

INTRODUCTION: Scientific research is a crucial section of health-related student education to ensure the competence of graduates. This study is the first to explore attitudes on research, willingness and motivation to conduct research, and barriers preventing this amid pharmacy students in Can Tho, Vietnam. METHODS: A cross-sectional online survey was performed on undergraduate pharmacy students (years four and five) from three public and private universities in Can Tho, Vietnam between April and May 2021. RESULTS: Of the 576 respondents, the majority accredited the significance of conducting research to the field of pharmacy (85.9%) with the motivation of improving the profession (81.6%). Public university respondents were more than twice as likely to have a positive attitude toward research (odds ratio [OR] = 2.88, 95% CI = 1.32-6.27) and be willing to conduct research (OR = 5.73, 95%CI = 3.5-9.37) than their private university counterparts. Very good or excellent academic performance was associated with a positive attitude (OR = 3.09, 95% CI = 1.46-6.53), willingness (OR = 3.2, 95%CI = 1.7-6.03), and increased motivation (OR = 2.42, 95% CI = 1.26-4.64) toward conducting research compared to respondents with average or lower academic performance. A lack of experience (63.5%), knowledge and skills (46%), and research training (51.7%) were the most common personal and systemic barriers to conducting research. CONCLUSIONS: Most students reported having a positive attitude and strong motivation toward research. These findings revealed an opportunity for pharmacy policymakers and educators to utilize national strategy to improve pharmacy education and the profession.

BACKGROUND: Early diagnosis of major depressive disorder (MDD) could enable timely interventions and effective management which subsequently improve clinical outcomes. However, quantitative and objective assessment tools for the suspected cases who present with depressive symptoms have not been fully established. METHODS: Based on a large-scale dataset (n = 363 subjects) collected with functional near-infrared spectroscopy (fNIRS) measurements during the verbal fluency task (VFT), this study proposed a data representation method for extracting spatiotemporal characteristics of NIRS signals, which emerged as candidate predictors in a two-phase machine learning framework to detect distinctive biomarkers for MDD. Supervised classifiers (e.g., support vector machine (SVM), k-nearest neighbors (KNN)) cooperated with cross-validation were implemented to evaluate the predictive capability of selected features in a training set. Another test set that was not involved in developing the algorithms enabled the independent assessment of the model's generalization. FINDINGS: For the classification with the optimal fusion features, the SVM classifier achieved the highest accuracy of 75.6% ± 4.7% in the nested cross-validation, and the correct prediction rate of 78.0% with a sensitivity of 75.0% and a specificity of 81.4% in the test set. Moreover, the multiway ANOVA test on clinical and demographic factors confirmed that twenty out of 39 optimal features were significantly correlated with the MDD-distinctive consequence. INTERPRETATION: The abnormal prefrontal activity of MDD may be quantified as diminished relative intensity and inappropriate activation timing of hemodynamic response, resulting in an objectively measurable biomarker for assessing cognitive deficits and screening MDD at the early stage. FUNDING: This study was funded by NUS iHeathtech Other Operating Expenses (R-722-000-004-731).

Purpose: New COVID-19 variants pose great challenges in protecting the success of vaccination programs. Awareness of community becomes an important component to prevent the spread of COVID-19. This study aims to analyze people's awareness of COVID-19 and identify the implications for optimal risk communication in Vietnam. Study Methods and Materials: A total of 341 individuals participated in an online cross-sectional study. Community awareness on COVID-19 was examined by using a structured questionnaire. Multivariable Tobit regression was used to examine associated factors with community awareness. Results: Our results indicated high levels of awareness of local COVID-19 situation, transmission risks, and preventive behavioral practices during the first week of social isolation. Higher awareness of local pandemic situation was associated with female respondents (Coef.: 6.19; 95% CI: 0.51; 11.87) and larger family sizes of above 5 people (Coef.: 9.00; -1.00; 19.00). Respondents between 35-44 years old were shown to be less aware of preventive behavioral practices than other age groups, including the group of participants above 44 years old (Coef.: -0.34; 95% CI: -0.67; -0.02). Lastly, participants who were "fairly satisfied" with information resources had awareness levels of preventive behavioral practices lower than that of "unsatisfied" respondents (Coef.: -0.45; 95% CI: 0.74; -0.16). Conclusion: This study offers crucial insights into the pandemic awareness of citizens and risk communication effectiveness during COVID-19 in Vietnam. The study findings shall serve the development of policies and interventions aimed at empowering individuals in the local and global fight against coronavirus.
RESUMEN
This study aims to clarify the bioactive constituents responsible for the anti-dementia effects of Ocimum sanctum Linn. ethanolic extract (OS) using olfactory bulbectomized (OBX) mice, an animal model of dementia. The effects of OS or its extract further fractionated with n-hexane (OS-H), ethyl acetate (OS-E), and n-butanol (OS-B) on the spatial cognitive deficits of OBX mice were elucidated by the modified Y-maze tests. The effects of the major constituents of the most active OS fraction were also elucidated using the reference drug donepezil. The administration of OS and OS-E ameliorated the spatial cognitive deficits caused by OBX, whereas OS-H or OS-B had no effect. Two major constituents, ursolic acid (URO) and oleanolic acid (OLE), and three minor constituents were isolated from OS-E. URO (6 and 12 mg/kg) and OLE (24 mg/kg) attenuated the OBX-induced cognitive deficits. URO (6 mg/kg) and donepezil reversed the OBX-induced down-regulation of vascular endothelial growth factor (VEGF) and choline acetyltransferase expression levels in the hippocampus. URO inhibited the ex vivo activity of acetylcholinesterase with similar efficacy to donepezil. URO inhibited the in vitro activity of acetylcholinesterase (IC50 = 106.5 µM), while the effects of OS, OS-E, and other isolated compounds were negligible. These findings suggest that URO and OLE are responsible for the anti-dementia action of OS extract, whereas URO possesses a more potent anti-dementia effect than its isomer OLE. The effects of URO are, at least in part, mediated by normalizing the function of central cholinergic systems and VEGF protein expression.

The association between selective serotonin reuptake inhibitor (SSRI) treatment and lower bone mineral density (BMD) remains controversial, and further research is required. This study aimed to compare the BMD, levels of bone formation and bone metabolism markers in medicated premenopausal Singaporean women with major depressive disorder (MDD) and matched healthy controls. We examined 45 women with MDD who received SSRI treatment (mean age: 37.64 ± 7) and 45 healthy controls (mean age: 38.1 ± 9.2). BMD at the lumbar spine, total hip and femoral neck were measured using dual-energy X-ray absorptiometry. We also measured bone formation markers, procollagen type 1 N-terminal propeptide (P1NP) and bone metabolism markers, osteoprotegerin (OPG) and receptor activator of nuclear factor-kappa-Β ligand (RANKL). There were no significant differences in the mean BMD in the lumbar spine (healthy controls: 1.04 ± 0.173 vs. MDD patients: 1.024 ± 0.145, p = 0.617, left hip (healthy controls: 0.823 ± 0.117 vs. MDD patients: 0.861 ± 0.146, p = 0.181) and right hip (healthy controls: 0.843 ± 0.117 vs. MDD patients: 0.85 ± 0.135, p = 0.784) between healthy controls and medicated patients with MDD. There were no significant differences in median P1NP (healthy controls: 35.9 vs. MDD patients: 37.3, p = 0.635), OPG (healthy controls: 2.6 vs. MDD patients: 2.7, p = 0.545), RANKL (healthy controls: 23.4 vs. MDD patients: 2178.93, p = 0.279) and RANKL/OPG ratio (healthy controls: 4.1 vs. MDD patients: 741.4, p = 0.279) between healthy controls and medicated patients with MDD. Chronic SSRI treatment might not be associated with low BMD in premenopausal Singaporean women who suffered from MDD. This finding may help female patients with MDD make an informed decision when considering the risks and benefits of SSRI treatment.
RESUMEN
BACKGROUND: As a method to acknowledge the devastating health and economic impacts of tobacco usage worldwide, telephone-based tobacco cessation counseling services have emerged as a potential tool to aid people in their quitting process. This study explores the satisfaction of smokers who use the QUITLINE service and factors associated with their quit attempts and cessation. METHODS: A cross-sectional survey of 110 participants was conducted from June to July 2016 at the Respiratory Center at Bach Mai Hospital, Hanoi, Vietnam. Multivariate logistic regression was used, and it was found that the percentage of people quitting smoking increased after using the service. RESULTS: In total, 65.5% of participants were completely satisfied with the counseling service. The mean score of staff/s capacity/responsiveness, motivation, and service convenience were 4.37 ± 0.78, 4.30 ± 0.81, and 4.27 ± 0.66, respectively. The smoking relapse rate was relatively high at 58.3%, which mainly resulted from cravings and busy work (26.2% and 14.3%, respectively). A higher satisfaction score in "Staffs' capacity and responsiveness" was negatively associated with "ever tried to quit smoking in consecutive 24 h" and actually quit smoking after receiving counseling. Meanwhile, a higher score in the "Motivation" domain was positively associated with both quit attempt indicators as well as actually quitting smoking after receiving counseling (OR = 9.48; 95%CI = 2.27; 39.57). CONCLUSIONS: These results suggest that it is crucial for decision makers to place more focus on countermeasures for smoking relapse and to strengthen the capacity of staff, especially in motivating clients. Interventions should also be maintained throughout a long period of time to prevent relapse.
RESUMEN
Introduction: Medical students have been serving as a key part of the frontline health workforce responding to the coronavirus disease 2019 (COVID-19) pandemic globally. Their contribution is especially important in the resource-scarce settings of developing nations such as Vietnam. Yet, the intention of medical students, in particular, nursing students, to participate in COVID-19 frontline prevention activities has not been well-understood. This study aimed to examine factors associated with the intentionto participate in COVID-19 frontline prevention activities among Vietnamese nursing students. Methods: A cross-sectional study was conducted on a total of 597 students in December 2020 in Hanoi, Vietnam. Information regarding the socioeconomic characteristics of participants, their source of COVID-19 related knowledge, and their perception and attitude toward participating in COVID-19 frontline activities [based on Theory of Planned Behavior (TPB)] was collected. A hierarchical regression model was employed to examine the association between intentions of students and associated factors. Results: A positive intention to participate in COVID-19 frontline prevention activities was found (mean score of 25.3 over 35; SD = 4.4; min = 5; max = 35). Attitude toward behavior, subjective norms, and perceived behavioral control (PBC) was found to be significantly associated with the intention of students. These variables explained the 37% variation in the intention of students in the model. Among three factors, subjective norm showed the strongest correlation with intention of students (ß = 0.358; p < 0.001). Obtaining information from official sources and community was also found to be positively correlated with intention to participate. Conclusion: Most of the respondents reported a positive intention to participate in COVID-19 frontline prevention activities. The findings suggested that the TPB was a good instrument to predict the intention to perform behavior among Vietnamese students. Enhancing the positive attitude of students, encouraging family and community supports, and providing adequately essential resources will contribute to optimizing the participation of students to confront COVID-19.

This study aimed to clarify the antidementia effects of ethanolic extract of Ocimum sanctum Linn. (OS) and its underlying mechanisms using olfactory bulbectomized (OBX) mice. OBX mice were treated daily with OS or a reference drug, donepezil (DNP). Spatial and nonspatial working memory performance was measured using a modified Y maze test and a novel object recognition test, respectively. Brain tissues of the animals were subjected to histochemical and neurochemical analysis. OS treatment attenuated OBX-induced impairment of spatial and nonspatial working memories. OBX induced degeneration of septal cholinergic neurons, enlargement of the lateral ventricles, and suppression of hippocampal neurogenesis. OS and DNP treatment also depressed these histological damages. OS administration reduced ex vivo activity of acetylcholinesterase in the brain. OBX diminished the expression levels of genes coding vascular endothelial growth factor (VEGF) and VEGF receptor type 2 (VEGFR2). Treatment with OS and DNP reversed OBX-induced decrease in VEGF gene and protein expression levels without affecting the expression of the VEGFR2 gene. These results demonstrate that the administration of OS can lessen the cognitive deficits and neurohistological damages of OBX and that these actions are, at least in part, mediated by the enhancement of central cholinergic systems and VEGF expression.
RESUMEN
A previously healthy 10-year-old girl developed painless visual loss. She was diagnosed with a spasm of accommodation confirmed by cycloplegic refraction. She was prescribed low-dose atropine and again reported acute visual loss that was inconsistent with the level of daily function.
