Background: Standard treatment for pleural infection includes of drainage and antibiotics. Chest tube drainage often fails if the fluid is loculated by fibrinous adhesions. Intrapleural fibrinolysis may facilitate pleural drainage. Objective: To evaluate the role of Streptokinase (STK) in the treatment of empyema and exudative pleural effusions. Subjects and method: A study included 34 patients (21 patients with exudative pleural effusions, 13 patients with empyema), aged 15-77 years. All patients received intrapleural STK daily with dose of 300.0000-500.000 UI for empyema and 300.000 UI for exudative pleural effusions. Response was assessed by clinical outcome, pleural fluid drainage, chest radiography, pleural ultrasound. Results: Mean pleural fluid drainage after STK instillation was higher in all patients. Pleural fluid drainage was 640 \xb1 494 ml before STK instillation and 823 \xb1 755 ml after STK instillation for empyema; 765 \xb1 691 ml before STK instillation and 1,033 \xb1 757 ml after STK instillation for exudative pleural effusions. The success rate of clinical outcome was 100%. Only 2 patients required decortications. Fever occurred in 3 patients (8.8%) and allergy in 1 patient (3%). Conclusions: Intrapleural STK was safe and effective in the treatment of empyema and exudative pleural effusions. STK prevents pleural adhesions and reduces the risks for surgery.

Introduction: Hepatitis C is a dangerous disease and if left untreated can have serious consequences to the patients. While hepatitis C is difficult to treat, its vaccine is still unavailable. Previous studies have showed that there is a low rate of drug users having HCV tests. This means HCV infections does not have any great importance attached to it amongst the drug user group.\r\n', u'Objectives: To discover the status of HCV infection among drug users in Hanoi and to analyse the associated factors. \r\n', u'Subjects and methods: This crossover descriptive study was conducted in Hanoi. Research objects consisted of only men within the 16 - 25 years old age group, who used heroin from 09/2005 to 12/2006. These participants were interviewed and tested for HIV, HCV and HBV.\r\n', u'Results: HCV prevalence is 35.1 %. Especially, the research has indicated that 100% of HIV infected cases have also contracted HCV. This co - infectious status can be a challenge to subjects when they experience ARV treatment. The mean age of surveyed participants is 19. 83.6% of them have attended secondary school. 30.1 % have taken part in illegal earning activities. \r\n', u'Conclusion: HCV infection was discovered in the early drug injection stage. The proportion of HIV infection among injecting drug users is 28.24 times compared to the smoking drug users.\r\n', u'

Although the need for social and emotional development has existed for decades, implementing Social-Emotional Learning (SEL) in schools continues to get considerable attention as newer generations enter the educational system. The demand for development is presently increasing daily. No one challenges the significance of social-emotional learning and the influence of organizations on adolescent development today. Social-emotional learning matches accurately with the priorities in modern schools. In Vietnam, quantitative research was conducted on 350 high school students. This research aimed to determine how students evaluate the implementation of the Social-emotional learning model in soft skills education. The results revealed students’ interest in implementing the social-emotional learning model into soft skills education. In addition, the results indicated the obstacles to implementing the social-emotional learning model in soft skills education. This study’s findings suggested that school leaders and background educators should implement the social-emotional learning model and support, monitor, and evaluate program efficacy to ensure program objectives are reached and students acquire social and emotional abilities. In addition, the study suggested that specific strategies are necessary to limit the factors that prevent the implementation of the social-emotional learning model in high schools.

BACKGROUND/OBJECTIVES: Although children of ethnic minority groups are experiencing a transition from a predominance of undernutrition to overnutrition, there is little evidence of a dual-malnutrition burden. Therefore, this study examined the double burden of malnutrition among school-aged ethnic minority children living in mountainous areas and its association with their diets. SUBJECTS/METHODS: A cross-sectional study was conducted from September 2019 to March 2020 in 3 mountainous areas of Northern Vietnam among 1,556 ethnic minority schoolaged children. The prevalence of under-nutrition (stunting and thinness) and over-nutrition (overweight and obesity) were measured using the WHO 2006 child growth standards (height-for-age and BMI-for-age Z-score). Nutritional practices were evaluated by the frequency of food consumption based on a 4-level scale. RESULTS: The percentage of children with stunting and thinness were 14.0% and 5.4%, respectively, while the figure for overweight/obesity was 9.4%. The factors positively associated with stunting were living in a family with more than 2 children or being Muong/ other ethnicities compared to the Tay ethnicity. Children who consumed fish/shrimps/crabs or milk weekly/daily were less likely to be undernourished compared to those who never consumed these foods. By contrast, children who never consumed foods rich in vitamin A precursors and vitamin A and fruit or consumed daily snacks/junk food were more likely to be overweight/obese. CONCLUSIONS Undernutrition remains a common issue among school-aged children and adolescents of ethnic minority groups, while over-nutrition exists simultaneously. Public health nutrition programs promoting adequate diets and positive lifestyle changes related to nutrition are essential to tackle the double burden of malnutrition among ethnic minority children.

Sphaeranthus africanus is commonly used as a traditional remedy for sore throats and pain treatment in Vietnam. The aerial parts have been studied for its anti-inflammatory and anti-proliferative properties. However, the antioxidant and antidiabetic potential of the plant has not been explored. In this work, hydrophilic extracts of the plant's aerial parts were prepared in order to investigate its antioxidant and anti-diabetic properties. Also, the cytotoxicity of the root was evaluated and compared to that of the aerial parts. All of the extracts inhibited lipid peroxidation with IC 50 values ranging from 2.05 to 3.56 µg/mL, indicating substantial antioxidant activity. At an IC 50 value of 4.80 μg/mL, the 50% ethanol extract exhibited the most potent inhibition of α-glucosidase. The cytotoxic activity of root extracts is 2 to 5-fold less than that of the aerial parts. Nevertheless, dichloromethane and ethyl acetate extracts of the root demonstrated a selective effect on leukemia cells, with no harm towards the normal HEK-293 cell line. This work provides a scientific support for the antioxidant and antidiabetic activity of the plant. Hence, it may find a promising material for the development of novel antioxidant and antidiabetic agents. More research can be conducted on the phytochemistry and anticancer activities of the plant’s root.

In the present study, bioactivity-guided extraction and isolation of the n-hexane fraction of the fruits of Vietnamese Schisandra sphenanthera led to the isolation of five dibenzocyclooctadiene lignans as gomisin N (1), schisandrin C (2), gomisin H (3), gomisin D (4), and gomisin C (5). All the isolates were tested for their inhibition of NO production in LPS-induced RAW 264.7 cells. Among them, compounds 4 and 5 showed weak inhibition of NO production with IC 50 values of 25.0 ± 1.6 and 24.8 ± 2.0 µM, respectively. Compound 1 exhibited NO production inhibition with an IC 50 value of 15.8 ± 2.1 µM, meanwhile, schisandrin C (2) showed the most potent inhibition with an IC 50 value of 8.5 ± 0.5 µM. In addition, compound 2 had a concentrationdependent inhibitory effect on the protein expression of the inflammatory enzymes iNOS and COX-2. Their physicochemical properties and ADMET data were predicted by in silico, indicating favorable drug-like properties as well as low acute oral toxicity. The results suggest that the fruit of S. sphenanthera and its phytochemical constituents might be used as anti-inflammatory agents.
