Vietnam is facing a shortage of skilled Environmental health workforce. A Training Needs Assessment was conducted to develop a list of environmental health tasks, a list of core competencies and ...assess the need for a Master of Environmental Health training program in Vietnam. To answer these questions, a cross-sectional study was conducted in Vietnam in 2017, using both qualitative and quantitative methods. The qualitative study involved a desk review, 29 in-depth interviews, two consultative workshops, and two expert meetings. For the quantitative component, 298 environmental health staff working at different levels completed a structured postal questionnaire. Results showed that different sectors were implementing various environmental health tasks but that there was currently no training program focusing on environmental health in Vietnam. Thirteen core competencies for a Master of Environmental Health were recommended. An urgent need to develop training programs to help building environmental health competencies at the Masters degree level was uniformly expressed. This could be achieved by developing a Master of Public Health with an Environmental Health stream in the short-term and a Master of Environmental Health program in the long-term.
Overweight and obesity have short-term and long-term effects on children's physical and mental health. These conditions currently have a tendency to increase among Vietnamese school children.
This ...study aimed to assess the quality of life among 8-10 year-old children in Vietnam.
This cross-sectional study was conducted with a sample of 264 children aged 8-10 years (including 88 obese children and 176 normal-weight ones) at two primary schools in Hanoi, Vietnam, in 2018 and their mothers or fathers participated in this study. The Vietnamese version of the Pediatric Quality of Life Inventory (PedsQL) 4.0 generic score scales were used to collect information from children and their parents about the children's quality-of-life. Mean and standard deviation of PedsQL scores were calculated. Independent t-test was used to compare mean scores between normal-weight and obese children.
Both child self reports and parent-proxy reports revealed that obese children had significantly lower scores for the total scales compared to normal weight children (80.7 versus 84.0;
< 0.05 for proxy reports and 77.6 vs 84.6;
< 0.001 for self reports). Total scale and subscale scores reported by parents were lower compared to those reported by children. Besides, 79% of normal weight children reported having PedsQL total scores in the highest quartile (≥75%), compared to 56.8 % of obese children (
= 0.01). Similarly, these proportions for parent-proxy reports were 79.5% and 65.9%, respectively (
< 0.05). Emotional scores were both found the lowest among the four subscales (71.6 for child self reports and 73.1 for parent-proxy reports).
Interventions aimed to improve quality of life of overweight and obese children in Vietnam should not focus only on diet adjustment and physical exercise but need to address all dimensions of health-related quality of life, especially emotional, social and school functioning.
There is an urgent need to carry out a costing exercise of the National Plan of Action for Nutrition (NPAN) 2017-2020 since the costing of nutrition-sensitive interventions was not entirely ...integrated and proved difficult to track the different sectors' contributions to the nutrition program.
To estimate the required budget for the activities of the NPAN in 2017-2020.
A standard ingredients approach activity-based costing was employed from the provider perspective.
The budget amount required for the NPAN activities in 2017, 2018, 2019 and 2020 would be US$ million 269.0; 310.5; 350.2 and 378.1, respectively. State budgets (especially from Ministry of Health) would be the main funding source for the NPAN. The budget required for implementing nutrition-sensitive interventions would be the largest share (more than 90%) while less than 10% are required for nutrition-specific interventions. The four interventions requiring the largest budget proportion (in 2020) included 1) Micronutrient supplementation (28.3%); 2) Breastfeeding & complementary feeding (21.9%); 3) Treatment of severe acute malnutrition (15.6%); and 4) Disease prevention and management (13.4%).
Based on the data from Vietnam National Health account and the data on GDP of Vietnam, the total required budget for the Vietnam NPAN 2017 (USD millions 5,082) as shares of the State budget for health, total State (Government) budget, and GDP would be 5.29%, 0.49% and 0.14%, respectively. From the estimation, Vietnam represents the nutrition strategy which prioritized on nutrition-sensitive actions, similar to most of the SUN Movement member countries.
Concrete is the most widely used man-made material in the world. Its versatility, strength, and relative ease of construction allow it to be used in the majority of civil infrastructure. However, ...concrete production plays a significant role in greenhouse gas emissions, accounting for around 8% of CO2 emissions worldwide. This thesis aims to reduce the demand for cement in concrete construction, thus reducing the carbon footprint of the concrete, by focusing on classifying and determining the effectiveness of seven different quarry by-products as partial replacements of cement.
Several methods were utilized in this study to characterize the quarry by-products: particle size distribution, helium pycnometry, X-Ray diffraction, X-Ray fluorescence, scanning electron microscopy, and a modified ASTM C1897 Method A that utilizes isothermal calorimetry and thermogravimetric analysis. These various methods allowed for the determination of the physical properties (e.g., gradation, specific gravity, and morphology) and the chemical properties (e.g., mineralogy and reactivity in a cementitious system).
The quarry by-products were classified as four granites, two limestones, and one greenstone. These quarry by-products were found to be non-pozzolanic and non-hydraulic. However, there are indications that there may be reactions with the various clays and feldspars in the quarry by-products with calcium hydroxide, which suggests a degree of reactivity that is not necessarily pozzolanic or hydraulic.

Several methods were utilized in this study to determine the physical properties (e.g., gradation, specific gravity, and morphology) and the chemical properties (e.g., mineralogy and reactivity in a cementitious solution) of the materials. The quarry by-products were classified as four granites, two limestones, and one greenstone. In general, these quarry by-products were not found to be reactive as a supplementary cementitious material, although the data may suggest some degree of reactivity between calcium hydroxide and the clays and/or feldspars in the quarry by-products.
INTRODUCTIONand importance: Pelvic osteosarcoma is quite rare and is a challenging task for orthopedic surgeons. This aim of this study is to present the first case report using customized 3D-printed ...prosthesis in Vietnam. CASE PRESENTATION57-year-old male was diagnosed with pelvic osteosarcoma. After neoadjuvant chemotherapy, we did limb-salvage surgery after partial pelvic resection. He had to undergo another surgery due to an infection complication that exposed part of the prosthesis. At 6 months follow-up, the patient's overall status was stable. VAS score when moving is 2/10. He can walk with one crutch. Patient is still being followed up and treated. CLININCAL DISCUSSIONManagement of pelvic osteosarcoma remains a challenging task for orthopedic surgeons. Advancements in customized 3D-printed prosthesis have been applied in treatment of pelvic osteosarcoma. Despite the complications, the results are promising. We believe that this is a new and innovative route in surgery of pelvic osteosarcoma. CONCLUSIONUsing customized 3D-printed prosthesis is a good way for management of pelvic osteosarcoma.
This article aims to describe the knowledge, attitude, frequency and level of consumption regarding non-alcoholic carbonated soft drinks (NCSD) among students from two high schools in Hanoi.
A ...cross-sectional survey including a semi-quantitative food frequency were conducted with 620 students from two high schools, one in the urban area and the other in the rural area of Hanoi city.
Data on knowledge of health risk associated with the consumption of NCSD showed neagtive results (only 11.9% of the students were able to identify all the contents of NCSD correctly, and 2.7% knew all eight health risks due to consumption of NCSD). Besides, 31.4% of all students did not have the intention to quit NCSD despite being aware of health risks associated with the consumption of NCSD. Students who reported consuming NCSD within one month prior to the study constituted 83.1%, and those who consumed NCSD 1-2 times/week accounted for the highest proportion, being 21.3%. On average, each student consumed 2,094 ml NCSD within one month prior to the study. Suburban students and male students consumed more than urban and female ones, respectively (
< 0.01).
Students should be equipped with information about NCSD related health risks and encouraged to consume less NCSD.
