Pyloric dysfunction is defined as hypertonia or spasm of the pyloric sphincter. The pylorus plays a key role in gastric emptying, but its function remains incompletely understood. Most studies have focused on gastroparesis regardless of the underlying pathophysiology. Few studies have reported pyloric dysfunction in patients with gastroparesis, and the diagnostic and treatment modalities for pyloric dysfunction are not well established. Recently developed diagnostic modalities assessing pyloric function, such as high-resolution antroduodenal manometry and endoluminal functional lumen imaging, are currently being evaluated. A variety of therapeutic interventions targeting the pylorus, including pharmacologic agents, intrapyloric botulinum injection, endoscopic balloon dilation, stent insertion, surgical pyloroplasty, and gastric peroral endoscopic pyloromyotomy, have been proposed. Among these, gastric peroral endoscopic pyloromyotomy has emerged as a novel, minimally invasive therapy with demonstrated efficacy and safety for refractory gastroparesis. This article reviews the pathophysiology of pyloric dysfunction and the potential diagnostic and therapeutic modalities based on the latest literature.

A 47-year-old female was admitted with progressive exertional dyspnea and diagnosed with anomalous drainage of the left pulmonary veins into the coronary sinus (CS), combined with an intact interatrial septum and a small patent ductus arteriosus (PDA). Multimodal imaging, including echocardiography, computed tomography, and cardiac catheterization, helps diagnosis, optimal management and monitoring. The patient successfully underwent surgical repair, which involved rerouting the left anomalous pulmonary veins into the left atrium through a surgically created atrial septal defect, while the CS continued to drain into the right atrium and the PDA was closed directly via a transpulmonary approach. The postoperative course was uneventful.

Globally, providing evidence on the economic burden of chronic obstructive pulmonary disease (COPD) is becoming essential as it assists the health authorities to efficiently allocate resources. This study aimed to summarize the literature on economic burden evidence for COPD from 1990 to 2019. This study examined the economic burden of COPD through a systematic review of studies from 1990 to 2019. A search was done in online databases, including Web of Science, PubMed/Medline, Scopus, and the Cochrane Library. After screening 12,734 studies, 43 articles that met the inclusion criteria were identified. General study information and data on direct, indirect, and intangible costs were extracted and converted to 2018 international dollars (Int$). Findings revealed that the total direct costs ranged from Int$ 52.08 (India) to Int$ 13,776.33 (Canada) across 16 studies, with drug costs rannging from Int$ 70.07 (Vietnam) to Int$ 8,706.9 (China) in 11 studies. Eight studies explored indirect costs, while one highlighted caregivers’ direct costs at approximately Int$ 1,207.8 (Greece). This study underscores the limited research on COPD caregivers’ economic burdens, particularly in developing countries, emphasizing the importance of increased research support, particularly in high-resource settings. This study provides information about the demographics and economic burden of COPD from 1990 to 2019. More strategies to reduce the frequency of hospital admissions and acute care services should be implemented to improve the quality of COPD patients’ lives and reduce the disease’s rising economic burden.

VIETNAMESE STUDENTS’ AWARENESS OF MENTAL HEALTH ISSUES AND ACADEMIC BURNOUT
This study explores the mental health status of high school students in Hanoi, Vietnam,
focusing on depression, anxiety, stress, and academic burnout. Using the Burnout Assessment
Tool (BAT-S-23) scale, the study assesses the prevalence of these conditions among students
and their awareness of these issues. The findings reveal significant levels of depression,
anxiety, stress, and burnout risk, with notable differences based on gender and grade
level. The study underscores the importance of mental health interventions and burnout
prevention programs in schools. It also highlights the potential of the BAT-S-23 scale as a
tool for assessing burnout. The results are expected to contribute to the development of
effective strategies for promoting student mental health and managing burnout, thereby
holding significant implications for the future of mental health management in the
Vietnamese educational setting. Future research should focus on identifying the specific
factors contributing to these mental health issues among high school students in Vietnam
and developing targeted interventions to address them. Despite some limitations, the
study offers important contributions to the ongoing efforts to promote mental health and academic success among students. ASEAN Journal of Psychiatry, Vol. 25 (3) April, 2024;1-11.

STRESS IN RELATIONSHIP WITH BURNOUT DUE TO COVID-19: THE MODERATING ROLE OF COPING STRATEGIES
This study investigates the relationship between stress and burnout related to the
COVID-19 pandemic, focusing on the moderating influence of positive and negative
coping strategies. In a cross-sectional survey involving 3,664 Vietnamese citizens aged 18
and above, the research explores the dynamics of stress and burnout symptoms associated
with the ongoing pandemic. The results reveal a negative impact of stress symptoms on
COVID-19-related burnout among the population. Notably, both positive and negative
coping strategies are identified as significant moderators in the interplay between stress
and burnout. This suggests that individuals’ coping mechanisms influence the severity
of stress and burnout experienced in dealing with COVID-19 challenges. These findings
contribute to the foundational understanding of the stress-burnout relationship during the
pandemic and provide essential insights for interventions. By recognizing the moderating
role of coping strategies, this study lays the groundwork for strategies aimed at enhancing
individuals’ coping abilities, ultimately reducing stress and burnout levels. These insights
hold the potential to assist individuals in adapting more effectively to the challenges posed
by the COVID-19 pandemic, fostering improved mental well-being in the face of ongoing
uncertainties. ASEAN Journal of Psychiatry, Vol. 25 (3) March, 2024; 1-10.

Objective: The risk of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from schoolchildren to their household and the protective effects of vaccination in these settings remain poorly understood. We assessed the transmission dynamics of schoolchildren with SARS-CoV-2 within their households and the protective effects of coronavirus disease (COVID-19) vaccination among household members in Viet Nam.
Methods: We estimated the attack rate, vaccine effectiveness and adjusted risk ratio (aRR) of factors associated with SARS-CoV-2 transmission to household contacts of children confirmed to have COVID-19 who attended three schools in Ha Nam, Phu Tho and Thanh Hoa provinces between September and December 2021 using multivariable regression with household-level random effects.
Results: This retrospective cohort study included 157 children infected with SARS-CoV-2 and their 540 household contacts. The attack rate among household contacts was 24.6% (133/540). Overall, vaccine effectiveness among household contacts was 39% (95% confidence interval [CI]: -1 to -63), higher among males than females and higher in adults aged >40 years. COVID-19 transmission was greater among female household contacts compared with males (aRR: 1.35, 95% CI: 0.94 to 1.95), although not statistically significant, and highest among those aged 19–39 years (aRR: 2.51, 95% CI: 1.50 to 4.21). Fully vaccinated household contacts had significantly lower infection risk (aRR: 0.46, 95% CI: 0.26 to 0.84).
Discussion: We found substantial onward transmission of SARS-CoV-2 from schoolchildren to household members, and older people were more likely to be protected by vaccination. We recommend that schoolchildren and all household members living with schoolchildren receive at least two doses of a COVID-19 vaccine. Recognizing the role of schoolchildren in the onward transmission of COVID-19 is an important lesson learned by Viet Nam that can help not only in managing other outbreaks but also in protecting schoolchildren by predicting the progress of the outbreak and preparing for a timely response.

Background:
s/Aims: Liver transplantation (LT) provides a favorable outcome for patients with hepatocellular carcinoma (HCC) and was launched in Vietnam in 2004. In this study, we evaluated the short-term and long-term outcomes of LT and its risk factors.
Methods:
This retrospective study analyzed HCC patients who underwent LT at Viet Duc University hospital, Vietnam, from 01/2012–03/2022. The following data were gathered: demographics, virus infection, tumor characteristics, alpha-fetoprotein (AFP) level, Child-Pugh and MELD scores, selection criteria, type of LT, complications, 30-day mortality, and disease-free and overall survival (DFS and OS).
Results:
Fifty four patients were included, the mean age was 55.39 ± 8.46 years. Nearly 90% had hepatitis B virus-related HCC. The median (interquartile range) AFP level was 16.2 (88.7) ng/mL. The average MELD score was 10.57 ± 5.95; the rate of Child-Pugh A and B were 70.4% and 18.5%, respectively. Nearly 40% of the patients were within Milan criteria, brain-dead donor was 83.3%. Hepatic and portal vein thrombosis occurred in 0% and 1.9%, respectively; hepatic artery thrombosis 1.9%, biliary leakage 5.6%, and postoperative hemorrhage 3.7%. Ninety-day mortality was 5.6%. Five-year DFS and OS were 79.3% and 81.4%, respectively. MELD score and ChildPugh score were predictive factors for DFS and OS (p < 0.05). In multivariate analysis, Child-Pugh score was the only significant factor (p < 0.05).
Conclusions
In Vietnam, LT is an effective therapy for HCC with an acceptable complication rate, mortality rate, and good survival outcomes, and should be further encouraged.
