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.

Objective: To investigate the antitumor effect of maesopsin 4-O-β-glucoside (TAT2) isolated from the leaves of Artocarpus tonkinensis (A. tonkinensis) A. Chev. ex Gagnep. Methods: The antitumor activity of TAT2 was evaluated in Lewis lung carcinoma (LLC) tumor-bearing mice. BALB/c mice had tumors induced by implantation with 2 × 10

During 8/1997- 10/1998, the coronary discase of 80 patients in the nuclear medicine department of the Army Central hospital 108 were evaluated by the technique SPECT- the myocardial perfusion with TC 99 m tetrofosmin spect accompanying with the strain test by dobutamin, of which 14 patients received the coronary angiography prior to and after the technique SPECT. The results haves shown that the technique SPECT with the myocardial perfusion of TC 99 m-tetro fosmin combining with the strain test had a high sensitivity and specificity in finding the ischemic lesion due to the coronary disease.
