BackgroundDespite progress made by the Millennium Development Goal (MDG) number 7.C, Vietnam still faces challenges with regard to the provision of access to safe drinking water and basic sanitation.ObjectiveThis paper describes household trends in access to improved water sources and sanitation facilities separately, and analyses factors associated with access to improved water sources and sanitation facilities in combination.DesignSecondary data from the Vietnam Multiple Indicator Cluster Survey in 2000, 2006, and 2011 were analyzed. Descriptive statistics and tests of significance describe trends over time in access to water and sanitation by location, demographic and socio-economic factors. Binary logistic regressions (2000, 2006, and 2011) describe associations between access to water and sanitation, and geographic, demographic, and socio-economic factors.ResultsThere have been some outstanding developments in access to improved water sources and sanitation facilities from 2000 to 2011. In 2011, the proportion of households with access to improved water sources and sanitation facilities reached 90% and 77%, respectively, meeting the 2015 MDG targets for safe drinking water and basic sanitation set at 88% and 75%, respectively. However, despite these achievements, in 2011, only 74% of households overall had access to combined improved drinking water and sanitation facilities. There were also stark differences between regions. In 2011, only 47% of households had access to both improved water and sanitation facilities in the Mekong River Delta compared with 94% in the Red River Delta. In 2011, households in urban compared to rural areas were more than twice as likely (odds ratio [OR]: 2.2; 95% confidence interval [CI]: 1.9–2.5) to have access to improved water and sanitation facilities in combination, and households in the highest compared with the lowest wealth quintile were over 40 times more likely (OR: 42.3; 95% CI: 29.8–60.0).ConclusionsMore efforts are required to increase household access to both improved water and sanitation facilities in the Mekong River Delta, South East and Central Highlands regions of Vietnam. There is also a need to address socio-economic factors associated with inadequate access to improved sanitation facilities.

Abstractobjective To evaluate the effectiveness of an intervention including psychoeducation and yoga for depression management at the primary healthcare level in one district in the H a Nam province, Vietnam.method The Patient Health Questionnaire-9 (PHQ-9) was used for depression screening and follow-up. Screened patients were further diagnosed with the Mini-International Neuropsychiatric Diagnostic Interview, by a trained general doctor. A linear regression model, adjusted for age, gender and baseline PHQ-9 score was used to assess whether the intervention leads to decreased depression severity compared to standard care in the control communes.results Both groups had similar PHQ-9 scores at baseline. The intervention group had on average significantly lower PHQ-9 scores after the intervention than the control group. Almost half of the patients in the intervention group recovered from depression, whereas nobody did in the control group.conclusion The results indicate that the intervention can be more effective than standard care in treating depression. The mean change of the PHQ-9 score after the intervention is deemed to be of clinical relevance.

There are major problems about irrational drug use among children. The treatment guidelines for respiratory illness and diarrhoea are not followed. Urgent actions are needed and should target all actors in the field, mothers, doctors, pharmacy staff, and authorities in order to improve this situation.

Background Thoracic duct stenosis or obstruction is one of the causes of chyluria. Although the diagnosis of chyluria is not difficult, treatment is still challenging. Although there have been no standard guidelines for the treatment of chyluria, interventional techniques now offer minimally invasive treatment options for chyluria such as interstitial lymphatic embolization, ductoplasty with balloon, or thoracic duct stenting. Case presentation  Here, we report a case of chyluria due to obstruction of the junction between the thoracic duct and subclavian vein in a 64 -year- old female patient. The patient was treated with balloon plasty for lymphovenous junction obstruction and interstitial lymphatic embolization for chyluria. However, chyluria was recurrent after 6 months so intranodal lymphangiography was performed. Anterograde thoracic duct was accessed through a transabdominal to the cisterna chyli which showed that the thoracic venous junction was re-obstruction. The patient was successfully treated by placing a uncovered drug-eluting stent with the size of 2.5 mm x 15 mm in length for resolving the thoracic occlusion. Conclusion This report demonstrates the feasibility of using thoracic duct stenting in the treatment chyluria due to lymphovenous junction obstruction.

Web tracking is currently recognized as one of the most important privacy threats on the Internet. Over the last years, many methodologies have been developed to uncover web trackers. Most of them are based on static code analysis and the use of predefined blacklists. However, our main hypothesis is that web tracking has started to use obfuscated programming, a transformation of code that renders previous detection methodologies ineffective and easy to evade. In this paper, we propose a new methodology based on dynamic code analysis that monitors the actual JavaScript calls made by the browser and compares them to the original source code of the website in order to detect obfuscated tracking. The main advantage of this approach is that detection cannot be evaded by code obfuscation. We applied this methodology to detect the use of canvas-font tracking and canvas fingerprinting on the top-10K most visited websites according to Alexa's ranking. Canvas-based tracking is a fingerprinting method based on JavaScript that uses the HTML5 canvas element to uniquely identify a user. Our results show that 10.44% of the top-10K websites use canvas-based tracking (canvas-font and canvas fingerprinting), while obfuscation was used in 2.25% of them. These results confirm our initial hypothesis that obfuscated programming in web tracking is already in use. Finally, we argue that canvas-based tracking can be more present in secondary pages than in the home page of websites.

Community health workforce plays a vital role in providing primary health care services as per the needs of residents; however, few studies have examined how nurses work within commune health centers (CHCs). Using qualitative methods including interviews and focus group discussions with key stakeholders, this study explores the roles, activities, and competencies required of community nursing services in rural districts within Vietnam. Two primary roles were identified: CHC nursing and family nursing. For the latter, in addition to providing people with general health care and health communication, they were expected to also deliver psychological care. CHC nursing fulfilled more roles and required four specific competencies: clinical care, communication, management, and planning/coordination activities. Despite these various roles serving people within a community, few ongoing efforts at either the local or national level are aimed at supporting these nurses. The study highlights the need for policy decisions via either developing a new job position policy or adapting the existing policy by integrating new roles into the existing positions of CHC nurses in Vietnam.

A 33-year-old nonsmoking Vietnamese man, without any past medical history was evaluated in another hospital in September 2018 for rapidly progressive shortness of breath. The chest radiograph showed a right pleural effusion. A thoracentesis was performed. On gross examination, the appearance of the pleural fluid was milky.
