Background: Patients with beta-thalassemia major are susceptible to malnutrition, yet limited evidence exists in Vietnam. This study aims to identify factors associated with underweight status among adults with beta-thalassemia major in Vietnam.
Methods: This cross-sectional study included 201 adults (≥18 years) with beta-thalassemia major. Underweight was defined as BMI < 18.5 kg/m². Logistic regression was used to examine factors associated with underweight status, including age, sex, ethnicity, place of residence, educational level, marital status, and employment status.
Results: Over half of the participants (54.2%) were underweight. Female (aOR = 0.30, 95% CI: 0.12–0.73, p-value=0.008) and married patients (aOR = 0.32, 95% CI: 0.13–0.79, p-value=0.013) were significantly associated with lower odds of underweight status compared to male and unmarried counterparts. Underweight patients had significantly lower fat mass, muscle mass, and bone mineral content, but higher total body water percentage compared to those with normal weight.
Conclusion: Underweight status is highly prevalent among adults with beta-thalassemia major in Vietnam, particularly among males and unmarried individuals. These findings underscore the need for targeted nutritional and psychosocial support strategies to improve care and quality of life for this vulnerable population. We recommend implementing tailored nutritional interventions to improve their nutritional status.

Purpose:
Simple virilizing congenital adrenal hyperplasia (SV-CAH) due to 21-hydroxylase deficiency (21-OHD) is an autosomal recessive disease caused by pathogenic variants of the CYP21A2 gene. Children with SV-CAH often experience delayed diagnosis, presenting with pseudo-precocious puberty in males and genital virilization in females. Genotyping is essential for diagnosis, treatment, optimization, and phenotype prediction. This study describes the clinical and genetic characteristics of SV-CAH to guide treatment strategies.
Methods:
From November 2016 to March 2023, 79 children (accounting for 34.3% of 230 CAH cases in the overall children’s cohort) from 75 families were classified as SV-CAH due to 21-OHD at the Vietnam National Children's Hospital. Forty-three children underwent CYP21A2 mutation analysis using multiplex ligation-dependent probe amplification and complete gene sequencing to detect pathogenic variants.
Results:
Median age at diagnosis was 4.5 years (interquartile range, 1 day–22.3 years). There were 38.0% males and 62.0% females. The most common symptoms were penile enlargement in males (53.3%) and clitoromegaly (87.8%) in females; the height standard deviation (SD) at diagnosis was 1.90±1.79 SD (-2.02 to 5.43) according to the World Health Organization; and bone age advancement was 4.65±2.59 years. Genetic analysis identified 21 pathogenic variants and 22 genotypes in 43 children. The most common variant was p.I173N (47.7%); the most common genotype was p.I173N/p.I173N (16.3%).
Conclusion
Children with SV-CAH are often diagnosed late. To avoid that, early genetic analysis should be prioritized, especially for children diagnosed through newborn screening programs. Determining the genotype is crucial for optimizing treatment strategies, ensuring personalized management, and avoiding overtreatment.

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.

Inflammation is a biological response caused by overactivation of the immune system and is controlled by immune cells via a variety of cytokines. The overproduction of pro-inflammatory cytokines enhances abnormal host immunity, resulting in diseases such as rheumatoid arthritis, cardiovascular disease, Alzheimer's disease, and cancer. Inhibiting the production of pro-inflammatory cytokines such as interleukin (IL)-12p40, IL-6, and tumor necrosis factor (TNF)-α might be one way to treat these conditions. Here, we investigated the anti-inflammatory activity of compounds isolated from Cimicifuga dahurica (Turcz.) Maxim., which is traditionally used as an antipyretic and analgesic in Korea. In primary cell culture assays, 12 compounds were found to inhibit the production of pro-inflammatory cytokines (IL-12p40, IL-6, and TNF-α) in vitro in bone marrow-derived dendritic cells stimulated with LPS.

In this report, we investigated the antioxidant (peroxyl radical-scavenging and reducing capacities) and anti-osteoporotic activities of extracts and isolated constituents (1 - 16) from the rhizomes of Kaempferia parviflora Wall. ex Baker on pre-osteoclastic RAW 264.7 cells. Compound 5 exhibited significant peroxyl radical-scavenging capacity, with TE value of 8.47 ± 0.52 µM, while compound 13 showed significant reducing capacity, with CUPRAC value of 5.66 ± 0.26 µM, at 10.0 µM. In addition, flavonoid compounds 2, 4, 6, 8, 10, 12, and terpene compound 15 showed significant inhibition of tartrate-resistant acid phosphatase (TRAP) in NF-κB ligand-induced osteoclastic RAW 264.7 cells, with values ranging from 16.97 ± 1.02 to 64.67 ± 2.76%. These results indicated that K. parviflora could be excellent sources for the antioxidant and anti-osteoporotic traditional medicinal plants.

In our search for natural soluble epoxide hydrolase (sEH) inhibitors from plants, an extract of the dried whole plants of Euphorbia supina Rafin was found to significantly inhibit sEH activity in vitro. Phytochemical investigation of E. supina resulted in isolation of 17 compounds (1 - 17), including triterpenes (1 - 4), phenolic compounds (5 - 8), and flavonoid derivatives (9 - 17). The structures of the isolated compounds were established mainly by extensive analysis of the 1D and 2D NMR, and MS data. All of the isolated compounds were evaluated for their sEH inhibitory activity. Among the isolated phenolic compounds, 8 was identified as a significant inhibitor of sEH, with an IC50 value of 15.4 +/- 1.3 microM. Additionally, a kinetic analysis of isolated compounds (2, 5, 8 - 11, 13, and 17) indicated that the inhibitory effects of flavonoid derivatives 10 and 11 were of mixed-type, with inhibitory constants (Ki) ranging from 3.6 +/- 0.8 to 21.8 +/- 1.0 microM, whereas compounds 2, 5, 8, 9, 13, and 17 were non-competitive inhibitors with inhibition Ki values ranging from 3.3 +/- 0.2 to 39.5 +/- 0.0 microM.

Phytochemical investigation of Kandelia candel resulted in the isolation of six triterpenes (1 - 5) and two glyceryl glycosides (6 and 7) and their structures were determined by comparing the spectroscopic data with those of reported values. In present study, we described the inhibitory effects of fractions and isolated compounds from K. candel on pro-inflammatory cytokines (IL-12 p40, IL-6, and TNF-alpha) production in lipopolysaccharide (LPS) stimulated bone marrow-derived dendritic cells (BMDCs). Results indicated that compounds 3, 6, and 7 showed potent inhibition on IL-6 production (IC50 values at less than 0.5 microM, respectively). Meanwhile, compounds 6 and 7 exhibited strong inhibitory effects on the production of TNF-alpha (IC50 values of 1.7 +/- 0.1 and 5.5 +/- 0.2 microM). Compounds 1 and 3 were also showed the inhibitory effects on IL-12 p40 production (IC50 values of 8.9 +/- 0.4 and 3.3 +/- 0.1 microM, respectively).
