Background:
Neutrophil elastase (NE) has been proposed as a potential biomarker for evaluating the severity and prognosis of bronchiectasis. This study aimed to compare bronchial lavage quantification of NE levels and activities with those of sputum.
Methods:
A cross-sectional study was conducted in which 24 Vietnamese adults with bronchiectasis were enrolled from June 2023 to August 2023. All participants underwent bronchoscopy to collect bronchial lavage fluid (BLF) from two bronchial locations: one in the region with the greatest bronchial dilatation and one in the normal bronchi or in patients with all lobes affected, the least abnormal lobe (abnormal BLF [ABLF] and normal BLF [NBLF], respectively). Spontaneously expectorated sputum was also collected.
Results:
Out of 24 cases, the prevalence of mild, moderate and severe bronchiectasis was 14/24 (58.4%), 5/24 (20.8%), and 5/24 (20.8%), respectively. NE concentration and activity were significantly higher in sputum and ABLF than in NBLF (p<0.001). Sputum and ABLF were highly correlated (r=0.841, p<0.001) with no significant difference in NE activity between sputum and ABLF. Higher levels of NE activity were seen in more severe bronchiectasis than in mild bronchiectasis in all samples but were only statistically significant for NE activity in sputum (r=0.418, p=0.042).
Conclusion
NE activity and concentration are elevated in areas of the lung most affected by bronchiectasis. Sputum is a valid surrogate of pulmonary NE levels, as they correlate strongly with ABLF and confirm in a Vietnamese population the relationship between NE activity and disease severity.

Annals of Hepato-Biliary-Pancreatic Surgery 2024;28(1):59-69
Background:
s/Aims: Pancreaticoduodenectomy (PD) is the only radical treatment for periampullary malignancies. Superior mesenteric artery (SMA) first approach combined with total meso-pancreas (MP) excision was conducted to improve the oncological results.There has not been any previous research of a technique that combines the SMA first approach and total MP excision with a detailed description of the MP macroscopical shape.
Methods:
We prospectively assessed 77 patients with periampullary malignancies between October 2020 and March 2022 (18 months). All patients had undergone PD with SMA first approach combined total MP excision. The perioperative indications, clinical data, intra-operative index, R0 resection rate of postoperative pathological specimens (especially mesopancreatic margin), postoperative complications, and follow-up results were evaluated.
Results:
The median operative time was 289.6 min (178−540 min), the median intraoperative blood loss was 209 mL (30−1,600 mL).Microscopically, there were 19 (24.7%) cases with metastatic MP, and five cases (6.5%) with R1-resection of the MP. The number of lymph nodes (LNs) harvested and metastatic LNs were 27.2 (maximum was 74) and 1.8 (maximum was 16), respectively. Some (46.8%) patients had pancreatic fistula, but mostly in grade A, with 7 patients (9.1%) who required re-operations. Some 18.2% of cases developed postoperative refractory diarrhea. The rate of in-hospital mortality was 1.3%.
Conclusions
The PD with SMA first approach combined TMpE for periampullary malignancies was effective in achieving superior oncological statistics (rate of MP R0-resection and number of total resected LNs) with non-inferior short-term outcomes. It is necessary to evaluate survival outcomes with long-term follow-up.

Background:
s/Aims: Hepatolithiasis and choledocholithiasis are frequent pathologies and unfortunately, with the current treatment strategies, the recurrence incidence is still high. This study aimed to assess the outcomes of laparoscopic choledochotomy using cholangioscopy via the percutaneous-choledochal tube for the treatment of hepatolithiasis and choledocholithiasis in Vietnamese patients.
Methods:
A cross-sectional study of patients with hepatolithiasis and/or choledocholithiasis who underwent laparoscopic choledochotomy using intraoperative cholangioscopy via percutaneous-choledochal tube at the Department of Hepatopancreatobiliary Surgery, 108 Military Central Hospital, from June 2017 to March 2020.
Results:
A total of 84 patients were analyzed. Most patients were females (56.0%) with a median age of 55.56 years. Among them, 41.8% of patients had previous abdominal operations, with 33.4% having choledochotomy. All patients underwent successful laparoscopic common bile duct exploration followed by T-tube drainage without needing to convert to open surgery. Most patients (64.3%) had both intrahepatic and extrahepatic stones. The rate of stones ≥ 10 mm in diameter was 64.3%. Biliary strictures were observed in 19.1% of patients during cholangioscopy. Complete removal of stones was achieved in 54.8% of patients. Intraoperative complications were encountered in two patients, but there was no need to change the strategy. The mean operating time was 121.85 ± 30.47 minutes.The early postoperative complication rate was 9.6%, and all patients were managed conservatively. The residual stones were removed through the T-tube tract by subsequent choledochoscopy in 34/38 patients, so the total success rate was 95.2%.
Conclusions
Laparoscopic choledochotomy combined with cholangioscopy through the percutaneous-choledochal tube is a safe and effective strategy for hepatolithiasis and/or choledocholithiasis, even in patients with a previous choledochotomy.

THE RELATIONSHIP BETWEEN DEPRESSION, ANXIETY, STRESS AND INTERNET USE AMONG HIGH SCHOOL STUDENTS
The prevalence of mental health issues among high school students has raised concerns
globally, with depression, anxiety, and stress being common challenges. This study
investigates the relationship between depression, anxiety, stress, and internet use among
high school students in Da Nang, Vietnam. The short Internet Addiction Test (s-IAT) and
Depression Anxiety Stress Scales (DASS-21) were used to assess internet addiction and
mental health symptoms. Data were analyzed using correlation analysis and regression
models. Results revealed significant positive correlations between internet use and
symptoms of stress, anxiety, and depression, highlighting the importance of addressing
problematic internet usage patterns. Additionally, associations were found between
demographic variables, such as parental occupations and socioeconomic status, and
mental health outcomes, emphasizing the interconnected nature of individual, familial,
and societal factors. The study underscores the need for targeted interventions to promote
healthy internet habits and mitigate potential harms among high school students. By
understanding the complex interplay between internet use and mental health outcomes,
stakeholders can develop effective strategies to support the well-being of adolescents in
an increasingly digital world. This research contributes to a deeper understanding of the
socio-ecological factors shaping adolescent mental health and informs future intervention
efforts. ASEAN Journal of Psychiatry, Vol. 25 (6) June, 2024; 1-16.

MENTAL HEALTH CARE NEEDS OF STUDENTS AT HO CHI MINH CITY OPEN UNIVERSITY, VIETNAM
Abstract
Objective: Today’s life with changes in many aspects has brought people significant
advantages and conveniences, but at the same time it has also caused physical and
mental consequences for each person, especially mental health problems. Science has
had many studies showing the impact of mental health on the quality of life, work
efficiency, learning outcomes, etc. Therefore, when facing mental health problems,
individuals need help to overcome the psychological problems they are facing to have
healthier and more positive mental health. The scope of this study refers to the need
for mental health care of students at Ho Chi Minh City Open University.
Methodology: This study, based on theories of mental health, models and solutions
to support mental health care, we built a questionnaire with 05 groups of basic needs
to help students improve their physical and mental health for healthy mental health.
Specifically, the care needs for self-satisfaction; The care needs for healthy emotional
expression; the need to care for satisfaction in relationships with others; the full care
needs are able to maintain a stable psychological state in life and the care needs
for improving the ability to cope with difficulties in learning and working. After
completion, we conducted a pilot survey on a small sample to check the reliability of
the questionnaire and calibrate the scale. With an alpha coefficient of 0.98-meaning
that the scale has a high reliability coefficient.
Results: The mean score results show that all 05 groups of needs included in the study
are of interest to the subjects and all have a desire to be met. Specifically: (1) The care
needs for self-satisfaction has an mean score of 3.13 and a standard deviation of 0.73,
a high level of need on the rating scale; care needs for expressing healthy emotions
has an mean score of 3.45 and a standard deviation of 0.58, a very high level of need
on the rating scale; the care needs for satisfaction in relationships with others has
an mean score of 3.34 and a standard deviation of 0.65, a very high level of need on
the rating scale; the full care needs are able to maintain a stable psychological state
in life has an mean score of 4.42 and a standard deviation of 0.60, a very high need
level in the assessment scale and the care needs for improving the ability to cope
with difficulties in learning and working has an mean score of 3.19 and a standard
deviation of 0.74, a high need level in the assessment scale.
Conclusion: The research results show that students of Ho Chi Minh City Open
University have a very high level of mental health care needs. Students clearly show
mental health care needs in all the contents that need to be cared for. Among the
component needs of mental health care needs, the need that students pay more
attention than the remaining needs is the full care needs are able to maintain a stable
psychological state in life. The need that students care less about than the remaining
needs is the care needs for self-satisfaction. ASEAN Journal of Psychiatry, Vol. 25 (10)

Salvia miltiorrhiza is a traditional medicinal plant used in Asian medicine for various therapeutic purposes. This plant contains numerous bioactive secondary metabolites, particularly abietane-type diterpenoids. In this study, 16 abietane-type diterpenoids were isolated from S. miltiorrhiza root extracts and structurally identified through advanced spectroscopic techniques. Among them, tanshinone IIA (6) and 15,16-dihydrotanshinone I (11) exhibited potent α-glucosidase inhibition, with IC 50 values of 48.38 ± 0.57 and 48.02 ± 0.47 µM, respectively. Enzyme kinetic studies revealed that these compounds served as non-competitive inhibitors of α-glucosidase. Our findings indicate that natural compounds from S. miltiorrhiza show promise as safe and effective α-glucosidase inhibitors, providing an alternative approach to diabetes treatment. This study contributes to the growing interest in utilizing natural sources for α-glucosidase inhibition and their potential application in healthcare and disease management.
