Background: Despite the success of National Action Plan on Nutrition program in reducing malnutrition among children under 5 years old in Vietnamin recent years, the rate of malnutrition inVietnamremains higher than that rate in other surrounding countries. The rate is especially high in mountainous areas. This study aims to explore the association between the mother’s nutrition care practice and the nutritional status of their children. Methods: 400 Children under 5 years of age and their mothers from Thanh Hoa—a Northern Province of Vietnam were included in this survey. Weight and height of the children were measured. Information related to the mother’s knowledge and practices pertaining to child health care and nutrition was collected. Results: The malnutrition rate was 29.3% by weight for age score (WAZ), 28.3% by height for age score (HAZ) and 10.0% by weight for height score (WHZ). 27.3% of mothers discarded the colostrum milk. 21.3% of children were fed with chewing rice before breastfeeding. Exclusive breastfeeding up to four months was 17.8% and exclusive breastfeeding rates for 6 months or more was 8.6%. Weaning practice before four months of age was 53.7%. There was an association between malnutrition with mother’s ethnic group, and the frequency of consumption of protein rich food. Conclusion: Malnutrition of ethnic minority children under five years of age is still a public health problem in the central mountainous areas ofVietnam. Inappropriate breastfeeding and weaning practice among ethnic minority women were associated with this high rate. Further effort should continue to improve the nutrition status of ethnic minority children under 5 years of age. Customized, culturally adapted interventions for ethnic minority women to strengthen their nutrition care knowledge, attitude and practice, especially breastfeeding and weaning practice are the key to achieving better nutrition status of their children.

Objective: To evaluate the anti-arthritic effects of Polygonatum kingianum rhizome extract using both in vitro and in vivo ***: Lipopolysaccharide-induced RAW 264.7 macrophages were treated with an ethanol extract of Polygonatum kingianum rhizomes at different concentrations to determine nitric oxide and prostaglandin E2(PGE2) production. For in vivo study, Polygonatum kingianum ethanol extract was further investigated for its antiinflammatory effect in a mouse model with collagen antibodyinduced arthritis. Phytochemical study of Polygonatum kingianum ethanol extract was also ***: Saponins(142 mg/g total yield) was the main component in the Polygonatum kingianum ethanol extract. 5α,8α-ergosterol peroxide,(E,E)-9-oxooctadeca-10,12-dienoic acid and 3-(2?-hydroxy-4?-methoxy-benzyl)-5,7-dihydroxy-8-methyl-chroman-4-one were isolated from the extract. Polygonatum kingianum ethanol extract exhibited potential anti-inflammatory effects by inhibiting nitric oxide and PGE2 production in RAW 264.7 cells in a dosedependent manner. The level of arthritis in mice with collagen antibody-induced arthritis was significantly reduced(P<0.01) after treatment with Polygonatum kingianum ethanol extract, particularly at a dose of 1 000 mg/kg body weight. Besides, the extract demonstrated the regulatory effects on serum tumor necrosis factoralpha, interleukin-6, and interleukin-10 in treated ***: Polygonatum kingianum ethanol extract has beneficial effects on inflammatory cytokine regulation and PGE2 inhibition in an experimental mouse model with collagen antibody-induced arthritis. The phytochemical screening reveals that the saponin, as the main component, and sterols(daucosterol and 5α,8α-ergosterol peroxide) from Polygonatum kingianum ethanol extract may contribute to its promising in vitro and in vivo anti-inflammatory activities.

Background: Regular physical activity(PA) has documented effects in prevention and treatment of many non-communicable diseases(NCDs).Physical inactivity is recognized as the fourth leading risk factor for premature death, worldwide. Despite these facts, physical inactivity is increasing,not only in high-income, but also in middle-and low-income countries. To address this negative trend, evidence-based methods to increase PA are needed. The purpose of this paper is to describe the implementation and assessment of 4 strategies designed to increase PA in ***: Four strategies were used: i) introduction and evaluation of an education and training program on the Swedish method of Physical Activity on Prescription(PAP) among health care professionals, ii) translation of the PAP evidence-based handbook, Physical Activity in the Prevention and Treatment of Disease(called FYSS in Swedish) into Vietnamese, iii) launch of a mass-media campaign to promote PA, and iv)advocacy to support development of PA guidelines in ***: The evaluation indicated that the participating health care professionals had a positive attitude to PAP. However, they also reported uncertainty in prescribing PA. FYSS was translated and disseminated successfully to health care professionals. A mass-media campaign identified the beneficial effects of PA to health care professionals, journalists, policy makers, and the public. Last, the process of developing national guidelines on PA was ***: This project led to enhanced awareness and appreciation of PA in the prevention and treatment of NCDs among health care professionals as well as initiation of national PA guidelines. Important lessons also were learned in the presentation of PAP, which will be considered when designing similar projects in the future.

Objective: To evaluate the knowledge of?nutrition?among mothers of children less than two years of age and changes in theoretical knowledge after a nutrition course. Method: A pilot study with a pre-post-test design. Thirty mothers of children who were less than two years of age from outside Hanoi participated in the study. The mothers’ knowledge of breastfeeding, supplementary food and diet when the child was suffering from diarrhea was collected using 19 self-reported questions. A one-day nutrition course at which the mothers answered the same questions before and after the course was run. Results: All the invited mothers were included in the study. There was a lack of knowledge about breastfeeding and nutrition at baseline, but it improved after the nutrition course. The greatest improvement in knowledge related to breastfeeding less than 30 minutes after delivery, not giving milk or fruit juice instead of breast milk, increasing the frequency of breastfeeding in the event of a smaller amount of milk and knowledge about giving supplementary food after six months. Moreover, the results revealed that the mothers reported better knowledge of the consumption and frequency of more healthy food supplements. Conclusion: There was a lack of knowledge about nutrition among the mothers with children less than two years of age. The course demonstrated effectiveness in every aspect of nutritional knowledge, tested in the posttest. The findings in this study could provide important information for authorities in the health sector to improve the nutritional state of children in the community.

We construct optimal k-step, 5- to 10-stage, explicit, strong-stability-preserving Hermite-Birkhoff (SSP HB) methods of order 12 with nonnegative coefficients by combining linear k-step methods of order 9 with 5- to 10-stage Runge-Kutta (RK) methods of order 4. Since these methods maintain the monotonicity property, they are well suited for solving hyperbolic PDEs by the method of lines after a spatial discretization. It is seen that the 8-step 7-stage HB methods have largest effective SSP coefficient among the HB methods of order 12 on hand. On Burgers’ equations, some of the new HB methods have larger maximum effective CFL numbers than Huang’s 7-step hybrid method of order 7, thus allowing larger step size.
