Background: This study examined the clinical application of the modified computed tomography severity index (MCTSI) and retroperitoneal extension classification (REC) in the evaluation of acute pancreatitis (AP) among Vietnamese patients. Methods: Data from 115 patients with AP between January 2022 and February 2024 were retrospectively analyzed. AP was diagnosed using the revised Atlanta classification (RAC) criteria. All computed tomography images were assessed by two abdominal radiologists with over 10 years of experience. Patients with AP secondary to blunt abdominal trauma were excluded. Results: The mean patient age was 49.8 ± 16.7 years, and the male:female ratio was 2.7:1. Necrotizing AP was observed in 24.3% of cases and extrapancreatic complications in 35.7%. Pancreatic and peripancreatic fluid collections were noted in 68.7% of cases, including 39.1% with acute peripancreatic fluid collection, 7.8% pseudocyst, 21.7% acute necrotic collection, and 4.3% walled-off necrosis. Based on MCTSI, the rates of mild, moderate, and severe AP were 28.7%, 53.9%, and 17.4%, respectively. Grades I, II, III, IV, and V REC represented 55.7%, 13.0%, 19.1%, 5.2%, and 7.0% of patients, respectively. MCTSI and REC were correlated with RAC in the evaluation of AP severity. Multivariate regression analysis revealed MCTSI to be an independent predictor of severe AP (odds ratio, 2.719; 95% confidence interval, 1.149–6.437; P = 0.023). MCTSI > 7 was the cutoff for predicting severe AP, with a sensitivity of 83.3%, specificity of 86.2%, and area under the curve of 0.944 (P < 0.001). Compared to the non-severe group, those with severe AP according to MCTSI had a longer hospitalization period (11 [9.25–16.75] days vs. 9 [6.50–12.00] days), a higher intensive care unit admission rate (30.0% vs. 3.2%), and greater mortality (15.0% vs. 1.1%). Conclusion In the assessment of AP severity, MCTSI and REC were correlated with RAC. MCTSI was an independent predictor of severe AP.

Objective: In Viet Nam, tuberculosis (TB) prevalence surveys revealed that approximately 98% of individuals with pulmonary TB have TB-presumptive abnormalities on chest radiographs, while 32% have no TB symptoms. This prompted the adoption of the “Double X” strategy, which combines chest radiographs and computer-aided detection with GeneXpert testing to screen for and diagnose TB among vulnerable populations. The aim of this study was to describe demographic, clinical and radiographic characteristics of symptomatic and asymptomatic Double X participants and to assess multilabel radiographic abnormalities on chest radiographs, interpreted by computer-aided detection software, as a possible tool for detecting TB-presumptive abnormalities, particularly for subclinical TB. Methods: Double X participants with TB-presumptive chest radiographs and/or TB symptoms and known risks were referred for confirmatory GeneXpert testing. The demographic and clinical characteristics of all Double X participants and the subset with confirmed TB were summarized. Univariate and multivariable logistic regression modelling was used to evaluate associations between participant characteristics and subclinical TB and between computer-aided detection multilabel radiographic abnormalities and TB. Results: From 2020 to 2022, 96 631 participants received chest radiographs, with 67 881 (70.2%) reporting no TB symptoms. Among 1144 individuals with Xpert-confirmed TB, 51.0% were subclinical. Subclinical TB prevalence was higher in older age groups, non-smokers, those previously treated for TB and the northern region. Among 11 computer-aided detection multilabel radiographic abnormalities, fibrosis was associated with higher odds of subclinical TB. Discussion: In Viet Nam, Double X community case finding detected pulmonary TB, including subclinical TB. Computer-aided detection software may have the potential to identify subclinical TB on chest radiographs by classifying multilabel radiographic abnormalities, but further research is needed.

A new crinane-type alkaloid, 6-epihydroxypowelline (1), together with six known alkaloids, lycorine (2), 2-O-acetyllycorine (3), deacetylbowdensine (4), 1-epideacetylbowdensine (5), 8-demethyl-3-oxomaritidine (6), and (-)-marithamine (7) were isolated from the whole parts of the Crinum latifolium L. in Vietnam. The structure identification of all compounds was determined by 1D, 2D-NMR as well as HR-ESI-MS spectroscopic techniques. The absolute configuration of these compounds was established by the ECD data. In addition, in vitro inhibition of acetylcholinesterase (AChE) activities was assessed for all isolated alkaloids. All alkaloids had AChE inhibitory effects, with IC50 values ranging from 32.65 ± 2.72 to 212.76 ± 8.30 µM and compound 3 displayed the strongest inhibition of AChE, with IC50 values of 32.65 ± 2.72 µM (in comparison to the reference drug, galanthamine, which had an IC50 of 2.40 ± 0.45 µM).

Objectives: The objective of this study was to characterize mental health issues among Vietnamese healthcare workers (HCWs) and to identify related factors. Methods: A cross-sectional study was conducted with 990 HCWs in 2021. Their mental health status was measured using the Depression, Anxiety, and Stress Scale. Results: In total, 49.9%, 52.3%, and 29.8% of respondents were found to have depression, anxiety, and stress, respectively. The multivariable linear regression model revealed that factors associated with increased anxiety scores included depression scores (β, 0.45; 95% confidence interval [CI], 0.39 to 0.51) and stress scores (β, 0.46; 95% CI, 0.41 to 0.52). Factors associated with increased depression scores included being frontline HCWs (β, 0.57; 95% CI, 0.10 to 1.10), stress scores (β, 0.50; 95% CI, 0.45 to 0.56), and anxiety scores (β, 0.41; 95% CI, 0.36 to 0.47), while working experience was associated with reduced depression scores (β, -0.08; 95% CI, -0.16 to -0.01). Factors associated with increased stress scores included working experience (β, 0.08; 95% CI, 0.00 to 0.16), personal protective equipment interference with daily activities (β, 0.55; 95% CI, 0.07 to 1.00), depression scores (β, 0.54; 95% CI, 0.48 to 0.59), and anxiety scores (β, 0.45; 95% CI, 0.39 to 0.50), while age was associated with reduced stress scores (β, -0.12; 95% CI, -0.20 to -0.05). Conclusions Specific interventions are necessary to enhance and promote the mental health of HCWs so they can successfully cope with the circumstances of the pandemic.
