    To determine the frequency and characteristics of patients with unsuccessful tuberculosis (TB) treatment. Random selection of TB case registers among all treatment units in Cambodia, two provinces in China, and Viet Nam. The data of two calendar years were analyzed to assess unsuccessful outcomes and their time of occurrence. Among the 33 309 TB patients, treatment was unsuccessful in respectively 10.1%, 3.0% and 9.1% of patients in Cambodia, China and Viet Nam. The risk of death was highest in Cambodia, higher among males than females, increased with age, and was more common among retreatment cases than new cases, and among patients with a high than a low sputum smear microscopy grade. Half of all deaths occurred in the first 2 months in Cambodia and within 11 weeks in China and Viet Nam. Median time to default was 3 months in Cambodia and Viet Nam, and about 2 months in China. Treatment was highly successful in the three study countries, with a low proportion of death and default. As the majority of defaulting occurs at the beginning of treatment, all countries should critically review their current policy of treatment support in this period.

    Tuberculosis (TB) case registers in Cambodia, two provinces in China and in Viet Nam. To determine completeness and consistency of information for quarterly reports on case finding and treatment outcome. A representative sample of TB case registers was selected in Cambodia, in two provinces in China and in Viet Nam. Quarterly reports were reproduced from double-entered, validated data to determine completeness and consistency. The dataset comprised 37,635 patient records in 2 calendar years. Only 0.2%, 3.6% and 1.1% of cases, respectively, in Cambodia, the two China provinces, and Viet Nam did not allow classification for the quarterly report on case finding. If the treatment outcome was reported as cured, it was correct in 99.9%, 85.7%, and 98.5% of the respective three jurisdictions: errors were mostly due to misclassification of completion as cure. Under-reporting of failures was more frequent than over-reporting in Cambodia and Viet Nam, while in the two provinces in China 84% of reported failures did not actually meet the bacteriological criterion. This evaluation demonstrates that recording essential information is exemplary in all three countries. It will be essential to carefully supervise the ability of staff to correctly define TB treatment outcome results in all three countries.

    Full Text Available Abstract Background The tuberculosis register is a critical data source for the information system of national tuberculosis control programs. From the information in the tuberculosis case register, it is possible to extend the standard analysis of age and sex characteristics among sputum smear-positive cases to all tuberculosis case categories. National tuberculosis programs might utilize such information to identify problems related to referral and access to diagnosis and treatment. Objectives Based on the electronic database we created, our objectives were to provide a detailed description of age and sex characteristics of tuberculosis patients at registration and to provide a comparison of age-specific sex characteristics among incident and prevalent sputum smear-positive cases. Methods A representative sample of tuberculosis case registers from 1 January 2003 to 31 December 2005 was selected in Cambodia, two provinces in China and Viet Nam. Age and sex characteristics of cases in the three separate prevalence surveys in the three jurisdictions (Cambodia: year 2002; China: year 2000; and Viet Nam: year 2006-2007 were obtained for comparison. Results A total 37,635 patients had been registered during the period in the selected units in the three countries. Cases were more frequently male in all three countries with 53%, 71%, and 69% in Cambodia, China, and Viet Nam, respectively. The ratios of the female-to-male odds in the notification system to that in the prevalence survey in smear-positive cases in Cambodia, China and Viet Nam were 2.1, 0.9, and 1.8, respectively. Because of the small proportion of extrapulmonary tuberculosis registered in China, we limited the analysis on age and sex distribution for extrapulmonary cases to Cambodia and Viet Nam. The proportion with extrapulmonary tuberculosis among all cases was 18.5% in Cambodia and 15.7% in Viet Nam, decreasing in frequency with increasing age. Conclusions Characteristics of patients

    Developing better health systems is the key to delivering optimal health services, although more evidence of effective strategies to do so is needed. Field surveys were conducted in Viet Nam and Cambodia to identify best practices in addressing health system bottlenecks to scale up disease control programs. The two countries were compared over time using a framework for analysis developed by the authors. In Viet Nam, a health system was in place for decades at the central to municipal levels, although it was fragile until the 1990s, when the government started taking measures. In Cambodia, the previous health system had been destroyed during previous internal conflict. In the post-conflict period, the health system was rebuilt with support for programs followed by centralization of health services. In different settings, different measures were taken to deal with similar bottlenecks. In Cambodia, vertical programs were dominant, so the government sought to centralize drug management to deal with shortages of essential drugs, while Viet Nam sought to mobilize resources to ensure drug distribution at all levels. This study shows there is no single successful approach to health systems, and a systemic approach needs to be taken because elimination of one bottleneck may reveal another. Efforts to enhance disease-specific programs may not always contribute to overall enhancement of the health system, and the best possible approach may not be the same in different countries. Further study is needed to explore common issues and principles for effective strategies to enhance health systems in different contexts.

    British companies are making more inroads in exploring for oil and gas off Viet Nam. British Gas plc won a 25 year production sharing contract for a license off southern Viet Nam in the South China Sea. Meantime, London independent Lasmo plc started seismic surveys on the block adjoining the British Gas block. Separately, Thailand and Viet Nam have reached agreement to jointly explore for and develop oil and gas found in waters claimed by both countries. Plans call for the two countries to draw up joint development plans covering oil and gas resources in the southeastern fringe of the Gulf of Thailand. Bangkok officials say they would have preferred to delineate maritime boundaries with Hanoi, but opted for the joint development accord, noting that Thailand and Malaysia had taken 12 years to resolve a similar dispute

    Viet Nam ratified the UNFCCC on 16 November 1994. The Hydro meteorological Service (HMS) has been assigned by the Government to take full responsibility for Climate Change issues and for implementing programs related to the objectives of the UNFCCC. The mount of GHG emission in Viet Nam is 111.7 Tg of CO 2 equivalent. It is expected that the amount will be increased dramatically in the coming decades because of fossil fuel consumption to meet energy demand in the country. Total CO 2 emissions would be increased from 101 Tg in 2000, to 139 Tg, 224 Tg and 433 Tg in 2010, 2020 and 2030 respectively. 13 GHG abatement options including 7 energy options and 6 non-energy options have been developed for this study.

    Tuberculosis (TB) remains a major cause of morbidity and mortality, and Viet Nam ranks 12 among the 22 high-TB burden countries. This study analyses surveillance data of the National Tuberculosis Control Programme in Viet Nam for the six-year period 2007 to 2012. During the study period, 598,877 TB cases (all forms) were notified, and 313,225 (52.3%) were new smear-positive cases. The case notification rate of new smear-positive cases was decreased, from 65 per 100,000 population in 2007 to 57 per 100,000 population in 2012; this decrease was observed for males and females in all age groups except males aged 0-14 and females aged 15-24 years. The male-to-female ratio of new smear-positive TB cases increased from 2.85 in 2007 to 3.02 in 2012. The average annual cure rate of new smear-positive cases was 90.3%. The high male-to-female ratio for new smear-positive TB cases in this notification data was lower than that from the 2007 TB prevalence survey in Viet Nam, suggesting a lower case detection for males. The decrease in new smear-positive case notification rates may reflect a decline in TB incidence in Viet Nam as several programmatic improvements have been made, although further research is required to increase case detection among young males and children.

    Revealing the dispersal of dengue viruses (DENV) in time and space is central to understanding their epidemiology. However, the processes that shape DENV transmission patterns at the scale of local populations are not well understood, particularly the impact of such factors as human population movement and urbanization. Herein, we investigated trends in the spatial dynamics of DENV-2 transmission in the highly endemic setting of southern Viet Nam. Through a phylogeographic analysis of 168 full-length DENV-2 genome sequences obtained from hospitalized dengue cases from 10 provinces in southern Viet Nam, we reveal substantial genetic diversity in both urban and rural areas, with multiple lineages identified in individual provinces within a single season, and indicative of frequent viral migration among communities. Focusing on the recently introduced Asian I genotype, we observed particularly high rates of viral exchange between adjacent geographic areas, and between Ho Chi Minh City, the primary urban center of this region, and populations across southern Viet Nam. Within Ho Chi Minh City, patterns of DENV movement appear consistent with a gravity model of virus dispersal, with viruses traveling across a gradient of population density. Overall, our analysis suggests that Ho Chi Minh City may act as a source population for the dispersal of DENV across southern Viet Nam, and provides further evidence that urban areas of Southeast Asia play a primary role in DENV transmission. However, these data also indicate that more rural areas are also capable of maintaining virus populations and hence fueling DENV evolution over multiple seasons.

    This paper reports on Viet Nam's offshore exploration and development. Hanoi tentatively awarded three of five remaining blocks of prime offshore South China Sea acreage to companies from Europe and the Far East, with a fourth such award reported imminent. And state owned Petrovietnam signed a production sharing contract (PSC) covering acreage in the same area to a combine of British Petroleum Co. plc and Norway's Den norske stats oljeselskap AS. Retention of one block in the area covered by Viet Nam's second bidding round fueled speculation Hanoi is holding it in reserve for U.S. companies to enter bidding, pending easing of U.S. trade sanctions against Viet Nam, Agence France France (AFP) reported. Second round blocks have been carved from a concession held by Vietsovpetro, a joint venture of Petrovietnam and the former Soviet Union. All are in the southern Con Sun basin of the South China Sea off the port of Vung Tao and on trend with Viet Nam's only producing oil fields

    Full Text Available INTRODUCTION: Since the 1980s, sex ratio at birth (male births per 100 female births has increased in many Asian countries as a result of selective abortions, but to date there has been no such evidence for Viet Nam. Our aim in this paper is to ascertain the situation with respect to sex ratio at birth in Viet Nam over the past five years. MATERIALS AND METHODS: Original data were obtained from sample population surveys in Viet Nam recording annual birth rates since 2000 of about 450,000 women, as well as from two successive birth surveys conducted for the first time in 2007 (1.1 million births. The annual population surveys include specific information on birth history and mothers' characteristics to be used for the analysis of trends and differentials in sex ratio at birth. RESULTS AND DISCUSSION: Birth history statistics indicate that the SRB in Viet Nam has recorded a steady growth since 2001. Starting from a level probably close to the biological standard of 105, the SRB reached 108 in 2005 and 112 in 2006, a value significantly above the normal level. An independent confirmation of these results comes from the surveys of births in health facilities which yielded a SRB of 110 in 2006-07. High SRB is linked to various factors such as access to modern health care, number of prenatal visits, level of higher education and employment status, young age, province of residence and prenatal sex determination. These results suggest that prenatal sex determination followed by selective abortion has recently become more common in Viet Nam. This recent trend is a consequence of various factors such as preference for sons, declining fertility, easy access to abortion, economic development as well as the increased availability of ultrasonography facilities.

    Since 1962, enterovirus D68 (EV-D68) has been implicated in multiple outbreaks and sporadic cases of respiratory infection worldwide, but especially in the USA and Europe with an increasing frequency between 2010 and 2014. We describe the detection, associated clinical features and molecular characterization of EV-D68 in central and southern Viet Nam between 2009 and 2015. Enterovirus/rhinovirus PCR positive respiratory or CSF samples taken from children and adults with respiratory/central nervous system infections in Viet Nam were tested by an EV-D68 specific PCR. The included samples were derived from 3 different observational studies conducted at referral hospitals across central and southern Viet Nam between 2009 and 2015. Whole-genome sequencing was carried out using a MiSeq based approach. Phylogenetic reconstruction and estimation of evolutionary rate and recombination were carried out in BEAST and Recombination Detection Program, respectively. EV-D68 was detected in 21/625 (3.4%) enterovirus/rhinovirus PCR positive respiratory samples but in none of the 15 CSF. All the EV-D68 patients were young children (age range: 11.8 - 24.5 months) and had moderate respiratory infections. Phylogenetic analysis suggested that the Vietnamese sequences clustered with those from Asian countries, of which 9 fell in the B1 clade, and the remaining sequence was identified within the A2 clade. One intra sub-clade recombination event was detected, representing the second reported recombination within EV-D68. The evolutionary rate of EV-D68 was estimated to be 5.12E -3 substitutions/site/year. Phylogenetic analysis indicated that the virus was imported into Viet Nam in 2008. We have demonstrated for the first time EV-D68 has been circulating at low levels in Viet Nam since 2008, associated with moderate acute respiratory infection in children. EV-D68 in Viet Nam is most closely related to Asian viruses, and clusters separately from recent US and European viruses that were

    To investigate changes that took place between 2006 and 2010 in the inequity gap for antenatal care attendance and delivery at health facilities among women in Viet Nam. Demographic, socioeconomic and obstetric data for women aged 15-49 years were extracted from Viet Nam's Multiple Indicator Cluster Survey for 2006 (MICS3) and 2010-2011 (MICS4). Multivariate logistic regression was performed to determine if antenatal care attendance and place of delivery were significantly associated with maternal education, maternal ethnicity (Kinh/Hoa versus other), household wealth and place of residence (urban versus rural). These independent variables correspond to the analytical framework of the Commission on Social Determinants of Health. Large discrepancies between urban and rural populations were found in both MICS3 and MICS4. Although antenatal care attendance and health facility delivery rates improved substantially between surveys (from 86.3 to 92.1% and from 76.2 to 89.7%, respectively), inequities increased, especially along ethnic lines. The risk of not giving birth in a health facility increased significantly among ethnic minority women living in rural areas. In 2006 this risk was nearly five times higher than among women of Kinh/Hoa (majority) ethnicity (odds ratio, OR: 4.67; 95% confidence interval, CI: 2.94-7.43); in 2010-2011 it had become nearly 20 times higher (OR: 18.8; 95% CI: 8.96-39.2). Inequity in maternal health care utilization has increased progressively in Viet Nam, primarily along ethnic lines, and vulnerable groups in the country are at risk of being left behind. Health-care decision-makers should target these groups through affirmative action and culturally sensitive interventions.

    To assess the blood alcohol concentration (BAC; dependent variable) of patients with road traffic injuries (RTIs) presenting at 3 provincial and central hospitals in the Socialist Republic of Viet Nam by age, sex, and road user type (independent variables). This survey formed part of the Viet Nam Road Traffic Injury Prevention Project, funded by Bloomberg Philanthropies. RTIs are a leading cause of death and disability in Viet Nam, with 14,690 deaths and 143,940 injuries reported by the Ministry of Health (MOH) in 2010. Research estimates suggest that motorcycle riders and passengers account for 60 percent of fatalities. Alcohol has long been suspected of being a leading cause of road traffic collisions and injuries. However, until now data on this relationship have been limited. A descriptive cross-sectional study measuring BAC in all consenting patients with RTIs presenting at 3 provincial or central hospitals between July 2009 and September 2010. All results were anonymous and summary information on key variables was sent to MOH and the World Health Organization (WHO) on a monthly basis. Of the 36,418 patients with RTIs presenting to these 3 hospitals between July 2009 and September 2010, BAC analysis was completed on 14,990 patients (41.2%), representing all patients with RTIs 15 years of age and above who consented to anonymous testing. BAC results ranged from 0 to 0.589 g/dL blood, with a mean of 0.0441 g/dL being the average concentration among all tested patients. Of all patients tested, 56.8 percent had no detectable alcohol in their system. Motorcycle riders were most commonly represented in the tested sample (70.7%), with 27.8 percent having a BAC above the legal limit (0.05 g/dL). Car or other vehicle drivers represented 2.7 percent of the sample, with 63.4 percent tested having a BAC above 0 g/dL, the legal limit for these road users. The results of this preliminary study indicate that 29.1 percent of all car drivers and motorcycle riders presenting at

    This paper reports that Viet Nam is on its way up in the petroleum world. After years of international isolation, the country is poised for a flurry of exploration by international oil companies in the early 1990s. Viet Nam has joined the Soviet Union as the only members of the now dissolved, formerly Moscow dominated, 10 nation Council for Mutual Economic Assistance (CMEA) that are self-sufficient in oil production. Moreover, Viet Nam has far outstripped neighboring China, which was not a CMEA member, in offshore oil flow even though China has a much larger Outer Continental Shelf. Prospects are that Viet Nam will continue to lead China in offshore oil production until 1995 at least

    Agricultural pesticide use in Viet Nam has more than tripled since 1990. However, pesticide legislation and regulations have not been developed in response to this large increase in usage, as a result of which pesticides pose a serious threat to human health and the environment. This paper identifies the need to improve pesticide regulations in Viet Nam through a comparative analysis of pesticide regulations in Viet Nam and the United States of America, where the rate of acute poisoning among agricultural workers is much lower than in Viet Nam and where information pertaining to pesticide regulations is made accessible to the public. The analysis identified several measures that would help to improve Viet Nam's pesticide regulations. These include enhancing pesticide legislation, clarifying the specific roles and active involvement of both the environmental and health sectors; performing a comprehensive risk-benefit evaluation of pesticide registration and management practices; improving regulations on pesticide suspension and cancellation, transport, storage and disposal; developing import and export policies and enhancing pesticide-related occupational safety programmes.

    Streptococcus suis is a common cause of adult bacterial meningitis in Viet Nam, and possibly other parts of Asia, yet this disabling infection has been largely neglected. Prevention, diagnosis and treatment are relatively straightforward and affordable but, in early 2007, no national diagnostic, case management or prevention guidelines existed in Viet Nam. Enhanced detection of S. suis infections was established in 2007 as part of a collaborative research programme between the National Hospital for Tropical Diseases, a key national hospital with very close links to the Ministry of Health, and a research group affiliated with Oxford University based in Viet Nam. The results were reported directly to policy-makers at the Ministry of Health. Viet Nam is a low-income country with a health-care system that has seen considerable improvements and increased autonomy. However, parts of the system remain fairly centralized the Ministry of Health. Following the improved detection and reporting of S. suis cases, the Ministry of Health issued guidance to all hospitals in Viet Nam on the clinical and laboratory diagnosis, treatment and prevention of S. suis. A public health laboratory diagnostic service was established at the National Institute of Hygiene and Epidemiology and training courses were conducted for clinicians and microbiologists. Ministry of Health guidance on surveillance and control of communicable diseases was updated to include a section on S. suis. Research collaborations can efficiently inform and influence national responses if they are well positioned to reach policy-makers.

    The molecular diagnosis of tuberculosis (TB) in Viet Nam is often based on the detection of insertion sequence (IS) 6110 in Mycobacterium tuberculosis. However, 8-11% of M. tuberculosis strains in South-East Asia do not contain this target and this undermines the validity of these molecular tests. We quantified the frequency of M. tuberculosis strains lacking IS6110 in rural Viet Nam and studied their epidemiological and clinical characteristics. Consecutively diagnosed adult TB patients in rural Southern Viet Nam submitted two sputum samples for culture, IS6110 restriction fragment length polymorphism (RFLP) spoligotyping and 15-loci variable number tandem repeat typing. Polymerase chain reaction (PCR) was performed to confirm the absence of IS6110 elements in strains lacking IS6110 hybridisation in RFLP. Among 2664 TB patient isolates examined, 109 (4.1%) had no IS6110 element. Compared to other strains, these no-copy strains were less often resistant to anti-tuberculosis drugs, particularly to streptomycin (adjusted OR 0.2, 95%CI 0.1-0.5), and showed significant geographic variation. No associations with TB history or demographic factors were found. Strains without the IS6110 target pose a problem in Viet Nam as regards false-negative molecular TB diagnosis in PCR. Compared to other strains circulating in Viet Nam, no-copy strains are more susceptible to anti-tuberculosis drugs.

    To estimate the cost of providing tuberculosis (TB) diagnosis and treatment packages at different levels of health facilities in Viet Nam. This was a retrospective costing study from the providers' perspective using a standard costing approach. We included typical services for TB diagnosis and treatment based on standard protocols. The least expensive TB service was the 6-month isoniazid preventive therapy regimen for latent tuberculous infection provided by district health centres (US$7.20-14.30, accounting for 0.3-0.7% of Viet Nam's per capita gross domestic product [GDP] of US$2052.30 in 2014). The cost of diagnosing and treating a patient with drug-susceptible TB (the most common type of TB) ranged between US$51.20 and US$180.70, and represented 2.5-8.8% of Viet Nam's per capita GDP in 2014. The most expensive TB service was the diagnosis and treatment of a multidrug-resistant TB case (US$1568.20-2391.20), accounting for 76.4-116.5% of Viet Nam's per capita GDP in 2014). The cost of TB diagnosis and treatment services in Viet Nam varied according to level of health facility, type of TB, different costing options, and different staff cost scenarios.

    In South Viet Nam, forest covers about 30% of the land area or approximately 6 000 000 ha. Hardwoods comprise about 80% of the timber stock. The total growing stock is not known exactly. Forest inventory is difficult in Viet Nam since some areas are inaccessible in the virgin forest. Overcutting by the population for domestic uses should also be mentioned together with fire damage, destruction by the war, etc. Practically all species of fibrous wood which are common in South- East Asia grow in Viet Nam. Pine trees especially account for about 2% of the forest and bamboo for 1%, and rubber trees, kenaf and jute are abundant. Valuable fibrous materials other than wood are agricultural wastes such as rice straw and bagasse. Table I presents a list of the most common fibrous plants of Viet Nam; their importance, however, cannot be evaluated. In addition, restricted numbers of these plants are consumed by the population of the region where they grow wild. Exploitation is, in fact, purely artisanal and tends merely to meet local needs. Cotton plants (Gossipium herbaceum) grow mainly in Central Viet Nam; the cotton product is not of good quality since the fibres are not very long.

To determine drug prescription adherence to national guidelines, to examine factors associated with an erroneous dosage of rifampin (RMP) and to evaluate the impact of an insufficient RMP dosage on treatment outcome. A representative sample of 30 treatment units was randomly selected. All patient treatment cards enrolled in these units were obtained, and data were double-entered and validated before calculating the adequacy of the individual drug prescriptions. Of 3412 tuberculosis treatment cards, 3225 (94.5%) had information on treatment regimen and the patient's weight. Treatment was successful in 89.4%. Prescriptions of tablets/vials conforming to recommendations were found for respectively 91.2%, 89.9%, 92.3% and 94.6% of the patients for RMP/isoniazid, pyrazinamide, ethambutol and streptomycin. Patients in the 25-39 kg weight bracket received insufficient dosages. This was almost entirely attributable to patients at the end of the weight bracket. Nevertheless, no significant association was found between treatment failure and death, body weight and insufficient RMP dosage. Adherence to national recommendations was high. RMP was given in insufficient dosage for patients at the end of a weight range bracket, but the under-dosage was small and did not measurably affect treatment outcome.

    To assess the acute respiratory infection (ARI) disease spectrum, duration of hospitalisation and outcome in children hospitalised with an ARI in Viet Nam. We conducted a retrospective descriptive study of ARI admissions to primary (Hoa Vang District Hospital), secondary (Da Nang Hospital for Women and Children) and tertiary (National Hospital of Paediatrics in Ha Noi) level hospitals in Viet Nam over 12 months (01/09/2015 to 31/08/2016). Acute respiratory infections accounted for 27.9% (37 436/134 061) of all paediatric admissions; nearly half (47.6%) of all children admitted to Hoa Vang District Hospital. Most (64.6%) of children hospitalised with an ARI were Viet Nam, characterised by prolonged hospitalisation for relatively mild disease. There is huge potential to reduce unnecessary hospital admission and cost. © 2017 John Wiley & Sons Ltd.

We describe results of a large, multicentre seroepidemiological and molecular study of the prevalence of HBV infection and blood-borne viral coinfections in Viet Nam. Individuals with varying risk factors for infection (n = 8654) were recruited from five centres; Ha Noi, Hai Phong, Da Nang, Khanh Hoa and Can Tho. A mean prevalence rate of 10.7% was observed and levels of HBsAg were significantly higher in injecting drug users (IDUs) (17.4%, n = 174/1000) and dialysis patients (14.3%, n = 82/575) than in lower-risk groups (9.4%; pViet Nam and also highlights the significant levels of blood-borne virus coinfections, which have important implications for hepatitis-related morbidity and development of effective management strategies.

    This article investigates impacts of hospital autonomization in Viet Nam employing a "decision-space" framework that examines how hospitals have used their increased discretion and to what effect. Analysis suggests autonomization is associated with increased revenue, increasing staff pay, and greater investment in infrastructure and equipment. But autonomization is also associated with more costly and intensive treatment methods of uncertain contribution to the Vietnamese government's stated goal of quality healthcare for all. Impacts of autonomization in district hospitals are less striking. Despite certain limitations, the analysis generates key insights into early stages of hospital autonomization in Viet Nam.

    In April 2009, an operational research fellow was placed within the Viet Nam National Tuberculosis Control Programme (NTP). Over the 6 years from 2010 to 2015, the OR fellow co-authored 21 tuberculosis research papers (as principal author in 15 [71%]). This constituted 23% of the 91 tuberculosis papers published in Viet Nam during this period. Of the 21 published papers, 16 (76%) contributed to changes in policy ( n = 8) and practice ( n = 8), and these in turn improved programme performance. Many papers also contributed important evidence for better programme planning. Highly motivated OR fellows embedded within NTPs can facilitate high-quality research and research uptake.

    Road traffic injuries are a leading cause of death and disability in Viet Nam. In 2008, official data reported 11 243 deaths and 7771 serious injuries on the roads, of which an estimated 60% of fatalities occur in motorcycle riders and passengers. In recognition of this problem, Viet Nam has had partial motorcycle helmet legislation since 1995. However, for a variety of reasons, implementation and enforcement have been limited. On 15 December 2007, Viet Nam's first comprehensive mandatory helmet law came into effect, covering all riders and passengers on all roads nationwide. Penalties increased ten-fold and cohorts of police were mobilized for enforcement. The Viet Nam national helmet legislation was developed and implemented by the National Traffic Safety Committee. Despite past barriers to enforcement, increased policing in 2008 led to 680 000 infringements being issued for non-helmet wearing. While changes in helmet wearing were not nationally observed, significant increases were documented in selected provinces in the first six months of the law's introduction. In Da Nang, helmet wearing increased from 27 to 99%. In the first three months after the law took effect, surveillance data from 20 urban and rural hospitals, found the risk of road traffic head injuries and deaths decreased by 16% and 18% respectively. Political leadership, intensive advanced public education and stringent enforcement have contributed to the successful implementation of the new law. Through continual monitoring of the legislation, loopholes detrimental to the effectiveness of the law have been identified and addressed.

    The paper tools used to monitor outreach work in all major cities in Viet Nam had substantial writing requirements for each contact with difficulty maintaining confidentiality. This paper describes the development of a Unique Identifier Code (UIC), a field data collection notebook (databook) and a computer data entry system in Viet Nam. The databook can document 40 individual clients and has space for commodity distribution, group contacts and needles/syringe collection for each month. Field implementation trials of the UIC and databook have been undertaken by more than 160 peer outreach workers to document their work with people who inject drugs (PWID) and sex workers (SW). Following an expanded trial in Hai Phong province, there have been requests for national circulation of the databook to be used by peer educators documenting outreach to PWID, SW and men who have sex with men. The standardized UIC and databook, in a variety of locally adapted formats, have now been introduced in more than 40 of the 63 provinces in Viet Nam. This development in Viet Nam is, to our knowledge, the first example of the combination of a confidential UIC and an innovative, simple pocket-sized paper instrument with associated customized data-entry software for documenting outreach.

    The Government of Viet Nam has recently formulated a national energy programme entitled Strategy and Policy of Sustainable Energy Development. Its aim is to define a development policy for the country for the period from 2000 to 2020. The main objectives of the national energy programme are: 1. Increasing energy efficiency and demand side management (DSM) 2. Expanding rural electrification 3. Defining an energy price policy (e.g. pricing such that revenues cover costs) 4. Minimizing environmental impacts 5. Encouraging private investment in the energy and electricity sectors 6. Energy supply security 7. Diversifying energy sources, and 8. Exploring the potential role of nuclear power in Viet Nam. In formulating this programme, one of the objectives has been to minimize environmental impacts, including those caused by the electricity sector. Nevertheless, the shortage of investment capital in Viet Nam and the difficulty of securing favourable financial arrangements are crucial obstacles to the introduction of new technology options to mitigate GHG emissions. Viet Nam views CDM as an opportunity to find ways to overcome such problems and expects that all GHG mitigating technologies will be considered equally under the CDM

The eight-member team comprised senior regulatory experts from Canada, France, Pakistan, Slovenia, United Arab Emirates and the United States of America, as well as three IAEA staff members. The IRRS team said in its preliminary assessment that Viet Nam had made progress since 2009, but that some key recommendations still needed to be addressed. Particular strengths identified by the team included: The commitment of VARANS staff to develop legislation and regulations in the field of nuclear and radiation safety; VARANS' efforts to implement practices that are in line with IAEA Safety Standards and internationally recognized good practices; A willingness to receive feedback regarding the efforts to establish and implement a regulation programme; and Progress made in developing the regulatory framework to support the introduction of nuclear power. The team identified the following areas as high-priority steps to further strengthen radiation and nuclear safety in Viet Nam: The effective independence of the regulatory decision-making process needs to be urgently addressed; Additional resources are needed to regulate existing radiation facilities and activities, as well as the country's research reactor; Efforts to increase the capacity of VARANS to regulate the developing nuclear power programme should continue; The draft Master Plan for the Development of Nuclear Power Infrastructure should be finalized

    To estimate the incremental delivery cost of human papillomavirus (HPV) vaccination of young adolescent girls in Peru, Uganda and Viet Nam. Data were collected from a sample of facilities that participated in five demonstration projects for hpv vaccine delivery: school-based delivery was used in Peru, Uganda and Viet Nam; health-centre-based delivery was also used in Viet Nam; and integrated delivery, which involved existing health services, was also used in Uganda. Microcosting methods were used to guide data collection on the use of resources (i.e. staff, supplies and equipment) and data were obtained from government, demonstration project and health centre administrative records. Delivery costs were expressed in 2009 United States dollars (US$). Exclusively project-related expenses and the cost of the vaccine were excluded. The economic delivery cost per vaccine dose ranged from US$ 1.44 for integrated outreach in Uganda to US$ 3.88 for school-based delivery in Peru. In Viet Nam, the lowest cost per dose was US$ 1.92 for health-centre-based delivery. Cost profiles revealed that, in general, the largest contributing factors were project start-up costs and recurrent personnel costs. The delivery cost of HPV vaccine was higher than published costs for traditional vaccines recommended by the Expanded Programme on Immunization (EPI). The cost of delivering HPV vaccine to young adolescent girls in Peru, Uganda and Viet Nam was higher than that for vaccines currently in the EPI schedule. The cost per vaccine dose was lower when delivery was integrated into existing health services.

    Sub-optimal infant and young child feeding (IYCF) practices are likely a significant contributor to high undernutrition rates in Viet Nam. To date, however, there has been no comprehensive review of IYCF practices in Viet Nam. The objectives of this paper were to review: 1) patterns/trends in IYCF in Viet Nam; 2) the barriers and facilitators to IYCF practices; and 3) interventions and policies and their effectiveness. Methods used include reviewing and analyzing existing data, summarizing and organizing the evidence into broad themes based on a pre-defined conceptual framework. Findings show that the proportion of children ever breastfed is almost universal and the median duration of breastfeeding is 13-18 months. However, exclusive breastfeeding for the first six months is low (8-17%) and appears to be declining over time. Information on complementary feeding is limited, but two key challenges are: early introduction, and low nutrient quality of complementary foods. Facilitators of optimal IYCF were support from 1) government progressive policies, 2) non-profit organizations and 3) family members. Barriers to optimal IYCF included 1) the lack of enforcement of, and compliance with the code of marketing breast milk substitutes, 2) inadequate knowledge among health care providers; and 3) maternal poor knowledge. These findings indicate that the evidence base on complementary feeding is weak in Viet Nam and needs to be strengthened. The review also reinforces that program and policy actions to improve IYCF in Viet Nam must target multiple stakeholders at different levels: the family, the health system and the private sector.

    Adequate utilization of services is critical to maximize the impact of counselling on infant and young child feeding (IYCF), but little is known about factors affecting utilization. Our study examined supply- and demand-side factors associated with the utilization of IYCF counselling services in Viet Nam. We used survey data from mothers with children Viet Nam, and may be relevant for increasing and sustaining use of nutrition services in similar contexts.

    Antiviral resistance has been reported in seasonal influenza A viruses and avian influenza A(H5N1) viruses in Viet Nam, raising concerns about the efficacy of treatment. We analysed specimens from two sources during the period 2009-2012: influenza-positive samples from influenza-like illness patients at sentinel clinics in northern Viet Nam and isolates from patients with confirmed A(H5N1) infections. Pyrosequencing was used to detect mutations: H275Y [for A(H1N1) and A(H5N1)], E119V [for A(H3N2)] and I117V [for A(H5N1)]. A neuraminidase inhibition assay was used to determine the Inhibitory Concentration 50 (IC₅₀) values for all influenza A and B isolates. There were 341 influenza A positive samples identified; influenza A(H1N1)pdm09 was identified most frequently (n = 215). In 2009, oseltamivir resistance was observed in 100% (19 of 19) of seasonal A(H1N1) isolates and 1.4% (3/215) of A(H1N1)pdm09 isolates. This H275Y mutation was not found in influenza subtypes A(H5N1) or A(H3N2) isolates. In Viet Nam, seasonal and A(H5N1) influenza vaccines are not currently available; thus, effective treatment is required. The presence of oseltamivir-resistant viruses is therefore a concern. Active surveillance for oseltamivir resistance among influenza viruses circulating in Viet Nam should be continued.

    Viet Nam is one of the brightest stars in the constellation of developing countries. Its remarkable achievements in reducing poverty and improving health and education outcomes are well known, and as a result it has enjoyed generous aid programmes. Viet Nam also has a reputation for taking a strong lead in disciplining its donors and pushing for more efficient and effective forms of aid delivery, both at home and internationally. This article discusses how efforts to improve the effectiveness of aid intersect with policy-making processes in the health sector. It presents a quantitative review of health aid flows in Viet Nam and a qualitative analysis of the aid environment using event analysis, participant observation and key informant interviews. The analysis reveals a complex and dynamic web of incentives influencing the implementation of the aid effectiveness agenda in the health sector. There are contradictory forces within the Ministry of Health, within government as a whole, within the donor community and between donors and government. Analytical frameworks drawn from the study of policy networks and governance can help explain these tensions. They suggest that governance of health aid in Viet Nam is characterised by multiple, overlapping 'policy networks' which cut across the traditional donor-government divide. The principles of aid effectiveness make sense for some of these communities, but for others they are irrational and may lead to a loss of influence and resources. However, sustained engagement combined with the building of strategic coalitions can overcome individual and institutional incentives. This article suggests that aid reform efforts should be understood not as a technocratic agenda but as a political process with all the associated tensions, perverse incentives and challenges. Partners thus need to recognise - and find new ways of making sense of - the complexity of forces affecting aid delivery.

    With the decline in funding for Viet Nam's response to the HIV epidemic, there is a need for evidence on the criteria to guide the prioritization of HIV programs. There is a gap in the research on the relative importance of multiple criteria for prioritizing a package of interventions. This study elicits preferences and the trade-offs made between different HIV programs by relevant stakeholders and decision-makers in Viet Nam. It also pays attention to how differences in social and professional characteristics of stakeholders and their agency affiliations shape preferences for HIV program criteria in Viet Nam. This study uses self-explicated ranking and discrete choice experiments to determine the relative importance of five criteria - effectiveness, feasibility, cost-effectiveness, rate of investment and prevention/treatment investment ratio - to stakeholders when they evaluate and select hypothetical HIV programs. The study includes 69 participants from government, civil society, and international development partners. Results of the discrete choice experiment show that overall the feasibility criterion is ranked highest in importance to the participants when choosing a hypothetical HIV program, followed by sustainability, treatment to prevention spending ratio, and effectiveness. The participant's work in management, programming, or decision-making has a significant effect on the importance of some criteria to the participant. In the self-explicated ranking effectiveness is the most important criterion and the cost-effectiveness criterion ranks low in importance across all groups. This study has shown that the preferred HIV program in Viet Nam is feasible, front-loaded for sustainability, has a higher proportion of investment on prevention, saves more lives and prevents more infections. Similarities in government and civil society rankings of criteria can create common grounds for future policy dialogues between stakeholders. Innovative models of planning should

    Viet Nam is experiencing a health transition from infectious to chronic disease. Data on cardiovascular diseases, including strokes, are limited. Data were randomly collected from six communities in Da Nang, Viet Nam, on participant demographics, medical history, blood pressure, anthropometrics and health behavior using World Health Organization (WHO) guidelines. Stroke symptoms were collected by self-report with the standardized Questionnaire for Verifying Stroke Free Status. Multivariate logistic regression was used to identify factors associated with the presence of stroke symptoms. One thousand six hundred and twenty one adults were examined with a mean age of 52.0 years (± 12.5 years), of which 56.1% were women. 27.3% of the participants were found to have hypertension, 26.2% used tobacco, and 16.1% were overweight. More than two-thirds of the participants with hypertension were unaware of their condition. Almost one fourth of the participants were identified by the questionnaire as previously experiencing at least one stroke symptom. Age, rural residence, and education were associated with the presence of stroke symptoms. Models adjusted for demographics found hypertension, high cholesterol, reported severe chest pain, former smoking, and being overweight to be associated with a higher prevalence of stroke symptoms. The high frequency of stroke symptoms in Da Nang calls for further evaluation and interventions to reduce hypertension and other risk factors for chronic disease in Viet Nam and other health transition countries.

    Influenza B viruses circulate throughout Viet Nam, and their activities vary by region. There have been two antigenically distinct lineages of influenza B viruses co-circulating in the past 20 years; however, only one lineage is selected as a component of contemporary trivalent seasonal influenza vaccines. To improve the understanding of circulating influenza B lineages and influenza vaccine mismatches, we report the virus lineages circulating in northern Viet Nam over an eight-year period (2007-2014). Lineages of 331 influenza B viruses were characterized by haemagglutination inhibition assay against standard reference ferret (Yamagata) and sheep (Victoria) antisera. Sequence analysis of the haemagglutinin gene was performed in 64 selected influenza B isolates. The proportion of influenza B lineages changed by year. The Yamagata lineage predominated in 2007, 2008 and 2012; the Victoria lineage predominated in 2009-2014 except 2012. The two lineages showed continuous evolution over time. The Northern Hemisphere's influenza vaccine components were mismatched with the predominant circulating viruses in 2007, 2009 and 2014. The seasonality of influenza B activity is more variable in tropical and subtropical regions than in temperate zones. Our data showed a common co-circulation of both influenza B lineages in northern Viet Nam, and it was difficult to predict which one was the predominant lineage. Quadrivalent influenza vaccines containing both lineages may improve the effectiveness of influenza vaccine programmes in the future.

    Viet Nam's Fourth National Anti-Tuberculosis Drug Resistance Survey was conducted in 2011. To determine the prevalence of resistance to the four main first-line anti-tuberculosis drugs in Viet Nam. Eighty clusters were selected using a probability proportion to size approach. Drug susceptibility testing (DST) against the four main first-line anti-tuberculosis drugs was performed. A total of 1629 smear-positive tuberculosis (TB) patients were eligible for culture. Of these, DST results were available for 1312 patients, including 1105 new TB cases, 195 previously treated TB cases and 12 cases with an unknown treatment history. The proportion of cases with resistance to any drug was 32.7% (95%CI 29.1-36.5) among new cases and 54.2% (95%CI 44.3-63.7) among previously treated cases. The proportion of multidrug-resistant TB (MDR-TB) cases was 4.0% (95%CI 2.5-5.4) in new cases and 23.3 (95%CI 16.7-29.9) in previously treated cases. The fourth drug resistance survey in Viet Nam found that the proportion of MDR-TB among new and previously treated cases was not significantly different from that in the 2005 survey. The National TB Programme should prioritise the detection and treatment of MDR-TB to reduce transmission of MDR-TB in the community.

    HPIVs are serologically and genetically grouped into four species that account for up to 10% of all hospitalizations due to acute respiratory infection in children under the age of five. Genetic and epidemiological data for the four HPIVs derived from two pediatric cohorts in Viet Nam are presented. Respiratory samples were screened for HPIV1-4 by real-time PCR. Demographic and clinical data of patients infected with different HPIV were compared. We used a hemi-nested PCR approach to generate viral genome sequences from HPIV-positive samples and conducted a comprehensive phylogenetic analysis. In total, 170 samples tested positive for HPIV. HPIV3 was most commonly detected in our cohort and 80 co-detections of HPIV with other respiratory viruses were found. Phylogenetic analyses suggest local endemic circulation as well as punctuated introductions of new HPIV lineages. Viral gene flow analysis revealed that Viet Nam is a net importer of viral genetic diversity. Epidemiological analyses imply similar disease severity for all HPIV species. HPIV sequences from Viet Nam formed local clusters and were interspersed with sequences from diverse geographic regions. Combined, this new knowledge will help to investigate global HPIV circulation patterns in more detail and ultimately define more suitable vaccine strains.

    The leading cause of death in children in developing countries is protein-energy malnutrition. In Viet Nam, 25.9% of children under 5 experience stunted growth and 6.6% are moderately wasted. Iron deficiency anaemia and vitamin A deficiency contribute to these and other malnutrition conditions. Given these factors, more evidence based approaches are required to improve understanding of current attitudes, opinions and behaviours of mothers with young children, in order to operationalise social marketing of nutrition commodities in Viet Nam. A literature review supported a rapid assessment and response method involving semi-structured interviews with 77 stakeholders and focus group discussions with 80 program beneficiaries from four geographic locations in the north and south of Viet Nam. Discussion agendas were developed to address key program issues with grounded theory utilized for data analysis. Data analysis highlighted challenges and opportunities within the six Ps of social marketing: Supply and demand side issues included: cost and the quality of products, the limited scale of interventions and promotional activities. Policy issues identified related to current policies that inhibited the broader promotion and distribution of micronutrient products, and opportunities for improved dialogue with policy partners. Partnerships further emphasized the need for public private partnerships to support the social change process. Implications for theory, policy, and practice indicates that rapid assessment and response is a cost-effective, pragmatic method of public health research, in resource constrained settings, to explore policies and behaviours amenable to change and build stakeholder engagement in the program.

    The study was conducted in a randomly selected sample of persons aged 15 years living in Ca Mau Province, southern Viet Nam. To estimate the prevalence of latent tuberculous infection (LTBI) in the general adult population of this province of Viet Nam. The secondary objective was to examine age and sex differences in prevalence. A cross-sectional survey was conducted in a cluster-random sample of the population. Clusters were subcommunes. The presence of LTBI was assessed using the QuantiFERON®-TB Gold In-Tube test system. QuantiFERON tests were performed among 1319 persons aged 15 years (77.7% of those selected). The overall prevalence of positive tests was 36.8% (95%CI 33.4-40.3). The prevalence of a positive test was lower in females than in males (31.0% vs. 44.7%, OR 0.57, 95%CI 0.45-0.72, P Viet Nam have evidence of LTBI. Although LTBI prevalence is higher in males, the sex difference is not as great as that for TB notification rates.

    Enterovirus A71 (EV-A71) is a major cause of hand, foot, and mouth disease (HFMD) and is particularly prevalent in parts of Southeast Asia, affecting thousands of children and infants each year. Revealing the evolutionary and epidemiological dynamics of EV-A71 through time and space is central to understanding its outbreak potential. We generated the full genome sequences of 200 EV-A71 strains sampled from various locations in Viet Nam between 2011 and 2013 and used these sequence data to determine the evolutionary history and phylodynamics of EV-A71 in Viet Nam, providing estimates of the effective reproduction number (Re) of the infection through time. In addition, we described the phylogeography of EV-A71 throughout Southeast Asia, documenting patterns of viral gene flow. Accordingly, our analysis reveals that a rapid genogroup switch from C4 to B5 likely took place during 2012 in Viet Nam. We show that the Re of subgenogroup C4 decreased during the time frame of sampling, whereas that of B5 increased and remained >1 at the end of 2013, corresponding to a rise in B5 prevalence. Our study reveals that the subgenogroup B5 virus that emerged into Viet Nam is closely related to variants that were responsible for large epidemics in Malaysia and Taiwan and therefore extends our knowledge regarding its associated area of endemicity. Subgenogroup B5 evidently has the potential to cause more widespread outbreaks across Southeast Asia. EV-A71 is one of many viruses that cause HFMD, a common syndrome that largely affects infants and children. HFMD usually causes only mild illness with no long-term consequences. Occasionally, however, severe infection may arise, especially in very young children, causing neurological complications and even death. EV-A71 is highly contagious and is associated with the most severe HFMD cases, with large and frequent epidemics of the virus recorded worldwide. Although major advances have been made in the development of a potential EV-A71

    Antimicrobial resistance is a major contemporary public health threat. Strategies to contain antimicrobial resistance have been comprehensively set forth, however in developing countries where the need for effective antimicrobials is greatest implementation has proved problematic. A better understanding of patterns and determinants of antibiotic use and resistance in emerging economies may permit more appropriately targeted interventions.Viet Nam, with a large population, high burden of infectious disease and relatively unrestricted access to medication, is an excellent case study of the difficulties faced by emerging economies in controlling antimicrobial resistance. Our working group conducted a situation analysis of the current patterns and determinants of antibiotic use and resistance in Viet Nam. International publications and local reports published between 1-1-1990 and 31-8-2012 were reviewed. All stakeholders analyzed the findings at a policy workshop and feasible recommendations were suggested to improve antibiotic use in Viet Nam.Here we report the results of our situation analysis focusing on: the healthcare system, drug regulation and supply; antibiotic resistance and infection control; and agricultural antibiotic use. Market reforms have improved healthcare access in Viet Nam and contributed to better health outcomes. However, increased accessibility has been accompanied by injudicious antibiotic use in hospitals and the community, with predictable escalation in bacterial resistance. Prescribing practices are poor and self-medication is common - often being the most affordable way to access healthcare. Many policies exist to regulate antibiotic use but enforcement is insufficient or lacking.Pneumococcal penicillin-resistance rates are the highest in Asia and carbapenem-resistant bacteria (notably NDM-1) have recently emerged. Hospital acquired infections, predominantly with multi-drug resistant Gram-negative organisms, place additional strain on

    2016-04-01

    The government of Viet Nam has made a commitment to build a Lifelong Learning Society by 2020. A range of related initiatives have been launched, including the Southeast Asian Ministers of Education Organization Centre for Lifelong Learning (SEAMEO CELLL) and "Book Day" - a day aimed at encouraging reading and raising awareness of its importance for the development of knowledge and skills. Viet Nam also aims to implement lifelong learning (LLL) activities in libraries, museums, cultural centres and clubs. The government of Viet Nam currently operates more than 11,900 Community Learning Centres (CLCs) and is in the process of both renovating and innovating public libraries and museums throughout the country. In addition to the work undertaken by the Viet Nam government, a number of enterprises have been initiated by non-governmental organisations and non-profit organisations to promote literacy and lifelong learning. This paper investigates some government initiatives focused on libraries and CLCs and their impact on reading promotion. Proposing a way forward, the paper confirms that Viet Nam's libraries and CLCs play an essential role in promoting reading and building a LLL Society.

The aim of this study was to describe the prevalence of and associations between early marriage, and IPV among adolescents and young adults in Viet Nam. Secondary analysis of data from the national Survey Assessment of Viet Namese Youth-Round II (SAVY-II) conducted in 2009-2010, which assessed a representative cohort of people aged 14 to 25 years recruited via a systematic household survey was undertaken. Prevalence was established using descriptive statistics. The association between early marriage and IPV was examined using multiple logistic regressions, adjusting for potential risk factors. Of 10,044 participants, 1,701 had ever married and were included in analyses. Early marriage (before age 18), and experiences of verbal, physical, or sexual IPV were more common among females than males. More young married men than women reported experiences of controlling behaviors by their partners. Early marriage, being illiterate, and exposure to sexual abuse were associated with experience of IPV among young females, but not among young males. Poverty and exposure to family violence was associated with IPV in both sexes. Addressing early marriage, low educational opportunities for girls, childhood sexual abuse, family violence, and poverty should be considered in strategies to reduce IPV in Viet Nam.

    Uneven precipitation in space and time together with mismanagement and lack of knowledge about quantity and quality of water resources, have caused water shortages for water supply to large cities and irrigation areas in many regions of Viet Nam in the dry season. The rainy season (from June to October) counts for 80% of the total annual rainfall, while the water volume of dry season (from November to May of the following year) accounts for 20% only. Lack of sufficient water volumes occurs in some areas where the pressure of a fast increasing population (1.3% per year on average in the last decade in Viet Nam), intensive agricultural and industrial uses is one of the major problems facing sustainable development. For those areas an accurate water assessment and balance at the riverbasin scale is needed to manage the exploitation and appropriate use of water resources and plan future development. The paper describes the preliminary phase of the pilot development of the river basin water balance for the Day River Basin in the Red River delta in Viet Nam. The Day river basin includes a 7,897 km² area in the south-western part of the Red River in Viet Nam. The total population in the Day river basin exceeds 8 millions inhabitants, including the Hanoi capital, Nam Dinh and other large towns. Agricultural land covered 390,294 ha in 2000 and this area is going to be increased by 14,000 ha in 2010 due to land reclamation and expansion toward the sea. Agricultural uses exploit about 90% of surface water resources in the Day river basin but have to compete with industrial and civil needs in the recent years. At the background of the brief characterization of the Day River Basin, we concentrate on the application of a water balance model integrated by an assessment of water quality after consumptive uses for civil, agricultural and industrial needs to assist water management in the basin. In addition, future development scenarios are taken into account, considering less

    A total of 167 tissue samples were collected from Foot-and-mouth disease (FMD) infected animals from 57 FMD outbreaks to detect the sero-type of the FMD virus by the ELISA technique. The ELISA kit has been prepared and standardised by the World Reference Laboratory (WRL), UK and supplied under a Research Contract as part of an FAO/IAEA Co-ordinated Research Project. Eight tissue samples from cattle and one tissue sample from pig were sent to WRL for further study on the sero-type and to characterize the FMD viruses present in Viet Nam. The study was carried out from March 1996 to May 1998 in the central region of Viet Nam and the FMD type O virus was detected in these outbreaks only. The FMD type O virus from cattle and the FMD type O virus from pig are two distinct FMD type O viruses in Viet Nam. (author)

The associations did not differ in subgroups defined by age, smoking, or alcohol consumption; however, associations differed between urban and rural participants (p-value for interaction of urban/rural status with salt consumption, p = 0.02, suggesting that higher salt consumption may be associated with higher systolic blood pressure in urban residents but lower systolic blood pressure in rural residents.Although there was no evidence of an association at a national level, associations of salt consumption with blood pressure differed between urban and rural residents in Viet Nam. The reasons for this differential association are not clear, and given the large rate of rural to urban migration experienced in Viet Nam, this topic warrants further investigation.

    The two currently licensed human papillomavirus (HPV) vaccines are highly efficacious in preventing cervical pre-cancers related to HPV 6, 11, 16 and 18. Before implementing a large-scale HPV vaccine campaign in Viet Nam, information about the prevalence of infection with the HPV vaccine types is required. This study was done in Can Tho, the province with the highest prevalence of cervical cancer in the south of Viet Nam, to explore the distribution of other high-risk types of HPV among married women in this province. The study employed a cross-sectional design with multistage sampling. A total of 1000 participants were randomly selected, interviewed and given gynaecological examinations. HPV infection status and HPV genotyping test were completed for all participants. A broad spectrum of HPV types was reported in this study. The prevalence of cases infected with HPV 16 and/or 18 was 7%; the prevalence of cases infected with other high-risk HPV types was 6%. The highest prevalence for single and multiple infections, as well as for high-risk infections, was reported for the youngest age group (less than 30 years). While it is relevant to implement an HPV vaccine campaign in Viet Nam due to the high prevalence of infection with HPV 16 and/or 18, it is important to note that one can be infected with multiple types of HPV. Vaccination does not protect against all types of high-risk HPV. Future vaccine campaigns should openly disclose this information to women receiving vaccines.

    Childhood tuberculosis causes significant morbidity and mortality in Southeast Asia, yet little is known about the epidemiology and clinical characteristics of this disease in Viet Nam. To determine the demographics, clinical presentations, radiographic and microbiologic findings, treatment regimens, and outcomes of children admitted with tuberculosis (TB) to a national referral hospital in Viet Nam. We conducted a retrospective case series study of children ≤ 15 years old with bacteriologically confirmed or clinically diagnosed TB admitted to a national referral hospital in Ha Noi, Viet Nam from January through December 2007. One hundred three children were identified: median age 5 years (IQR 2-10), 44% female, 99% Kinh ethnicity, 27% residing in Ha Noi, 88% with BCG vaccination, 27% with known TB contact, and 38% malnourished. Intrathoracic TB was present in 62%, extrathoracic in 52%, both intra and extrathoracic in 19%, and undetermined site in 5%. The most common extrathoracic manifestation was peripheral lymphadenitis, and children under 5 were more likely to have miliary TB or both intra and extrathoracic TB. Fever and failure to thrive were common presenting symptoms among all participants (65% and 56%, respectively), 66% of those with intrathoracic TB presented with cough, and 92% of those with TB meningitis presented with severe neurologic impairment. Acid-fast bacilli smears and mycobacterial cultures were positive in 18% and 21% of children tested, and histopathology was positive in 88% of those biopsied. There were no adverse drug reactions necessitating change in therapy, and no inpatient mortality. Extrathoracic TB was common, treatment well tolerated and clinical outcomes excellent. Culture confirmation rates were low and emphasize the need for improved diagnostics.

    Breastfeeding is recognized as the single most cost-effective intervention to reduce child morbidity and mortality. However, few studies have explored perceived barriers to breastfeeding and factors associated with breastfeeding intent among mothers of newborn babies in Viet Nam. We conducted a study to assess breastfeeding initiation rates, intent to breastfeed exclusively for 6 months or more and perceived barriers to breastfeed among mothers of newborn babies in Da Nang, Viet Nam. We conducted a cross-sectional questionnaire survey of mothers in the postnatal wards of Da Nang Hospital for Women and Children in central Viet Nam from 10 February 2017 to 24 February 2017, following implementation of the World Health Organization (WHO) Essential Newborn Care (ENC) package. Of 286 mothers surveyed, 259 (90.6%) initiated breastfeeding; 203/258 (78.7%) within 1 hour (h) of birth. Most (207, 72.4%) mothers indicated intent to breastfeed exclusively for 6 months or more, but this was lower among mothers of preterm babies (82.2% versus 20.0%, p  < 0.001) and those without post-secondary school education (74.8% versus 55.6%, p  = 0.02). Amongst mothers struggling to establish breastfeeding, 18/27 (66.7%) had a Cesarean section. Planned non-exclusive breastfeeding was mostly (39, 60.9%) motivated by mothers' concern that their milk supply would be insufficient for their baby's growth requirements. Most mothers had good knowledge about the benefits of breastfeeding and indicated strong decision autonomy. We documented high rates of early breastfeeding establishment and intent to breastfeed exclusively for 6 months or more. This probably reflects high levels of maternal education and successful implementation of the WHO ENC package. Mothers of premature babies may benefit from additional support.

    Gestational diabetes mellitus (GDM) is increasing and is a risk for type 2 diabetes. Evidence supporting screening comes mostly from high-income countries. We aimed to determine prevalence and outcomes in urban Viet Nam. We compared the proposed International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criterion, requiring one positive value on the 75-g glucose tolerance test, to the 2010 American Diabetes Association (ADA) criterion, requiring two positive values. We conducted a prospective cohort study in Ho Chi Minh City, Viet Nam. Study participants were 2,772 women undergoing routine prenatal care who underwent a 75-g glucose tolerance test and interview around 28 (range 24-32) wk. GDM diagnosed by the ADA criterion was treated by local protocol. Women with GDM by the IADPSG criterion but not the ADA criterion were termed "borderline" and received standard care. 2,702 women (97.5% of cohort) were followed until discharge after delivery. GDM was diagnosed in 164 participants (6.1%) by the ADA criterion, 550 (20.3%) by the IADPSG criterion. Mean body mass index was 20.45 kg/m(2) in women with out GDM, 21.10 in women with borderline GDM, and 21.81 in women with GDM, pViet Nam. Women with GDM by the IADPSG criterion were at risk of preterm delivery and neonatal hypoglycaemia, although this criterion resulted in 20% of pregnant women being positive for GDM. The ability to cope with such a large number of cases and prevent associated adverse outcomes needs to be demonstrated before recommending widespread screening.

    The programmatic management of drug-resistant tuberculosis (TB) in Viet Nam has been rapidly scaled up since 2009. To document the annual numbers of patients enrolled for multidrug-resistant tuberculosis (MDR-TB) treatment during 2010-2014 and to determine characteristics and treatment outcomes of patients initiating treatment during 2010-2012. A retrospective cohort study using national reports and data from the national electronic data system for drug-resistant TB. The number of patients enrolled annually for MDR-TB treatment increased from 97 in 2010 to 1522 in 2014. The majority of patients were middle-aged men who had pulmonary disease and had failed a retreatment regimen; 77% had received ⩾2 courses of TB treatment. Favourable outcomes (cured and treatment completed) were attained in 73% of patients. Unfavourable outcomes included loss to follow-up (12.5%), death (8%) and failure (6.3%). Having had ⩾2 previous treatment courses and being human immunodeficiency virus-positive were associated with unfavourable outcomes. Increasing numbers of patients are being treated for MDR-TB each year with good treatment outcomes under national programme management in Viet Nam. However, there is a need to increase case detection-currently at 30% of the estimated 5100 MDR-TB cases per year, reduce adverse outcomes and improve monitoring and evaluation.

To determine 1) at national level between 2011 and 2013, the relationship between human immunodeficiency virus (HIV) testing, uptake of TB-HIV interventions and adverse treatment outcomes among TB-HIV patients; and 2) in HCMC in 2013, patient characteristics associated with adverse outcomes. An ecological study reviewing aggregate nationwide data and a retrospective cohort review in HCMC. Nationwide, from 2011 to 2013, HIV testing increased in TB patients from 58% to 68% and antiretroviral therapy (ART) increased in TB-HIV patients from 54% to 63%. Adverse treatment outcomes in TB-HIV patients increased from 24% to 27%, largely due to transfer out (5-9% increase) and death. The Northern and Highland regions showed poor uptake of TB-HIV interventions. In HCMC, 303 (27%) of 1110 TB-HIV patients had adverse outcomes, with higher risks observed in those with previously treated TB, those diagnosed as HIV-positive before TB onset and those never placed on cotrimoxazole or ART. Despite improving HIV testing rates and TB-HIV interventions, adverse outcomes in TB-HIV patients remain at about 26%. Characteristics predicting higher risk of adverse outcomes must be addressed if Viet Nam wishes to end the TB epidemic by 2030.

    Vietnamese is one of the 20 most commonly spoken languages in the world; however, there are no standardised tools to assess Vietnamese children's speech. This study aimed to validate and norm the Vietnamese version of the Intelligibility in Context Scale (ICS-VN). Data were collected from parents of 181 children (aged 2;0-5;11) living in Ha Noi, Northern Viet Nam. The mean ICS-VN score was 4.43 (out of a maximum of 5), indicating that children were 'usually' to 'always' intelligible; however, item-level scores demonstrated significant differences between communication partners. Children with parental concerns about speech and language had significantly lower mean scores than children without parental concerns. Scores also differed by children's age, parents' occupation and mothers' education level but not by sex of child or fathers' education level. The ICS-VN had good psychometric properties indicating it to be a valid tool for use with Vietnamese-speaking children in Northern Viet Nam.

    Setting: Since 2011, tuberculosis (TB) clinics in Ho Chi Minh City (HCMC), Viet Nam, have been entering data from a paper-based TB treatment register into an electronic database known as VITIMES (Viet Nam TB Information Management Electronic System), which is currently used in parallel with the paper system. Objective: To evaluate the sensitivity, completeness and agreement of data in VITIMES with that of paper-based registers among TB patients co-infected with the human immunodeficiency virus (HIV) being treated for TB in HCMC. Design: This was a retrospective data review of all TB-HIV patients receiving anti-tuberculosis treatment in each of the 24 district TB clinics in HCMC in 2013. Data were abstracted from the paper-based TB treatment registers at district level and extracted electronically at the provincial level. Records were matched based on name, age and address. The sensitivity, completeness and agreement of the electronic data were compared with data from the paper system. Results: The findings showed that the electronic system had high sensitivity (99.2%), high completeness (87-99%) and high agreement (κ 0.78-0.97) for all variables. Conclusion: The results of this study suggest that data are being correctly entered into VITIMES and that patient data can be directly entered into VITIMES instead of having a parallel, paper-based system.

    Adverse Events Following Immunization in Viet Nam in 2013 led to substantial reductions in hepatitis B vaccination coverage (both the birth dose and the three-dose series). In order to estimate the impact of the reduction in vaccination coverage on hepatitis B transmission and future mortality, a widely-used mathematical model was applied to the data from Viet Nam. Using the model, we estimated the number of chronic infections and deaths that are expected to occur in the birth cohort in 2013 and the number of excessive infections and deaths attributable to the drop in immunization coverage in 2013. An excess of 90,137 chronic infections and 17,456 future deaths were estimated to occur in the 2013 birth cohort due to the drop in vaccination coverage. This analysis highlights the importance of maintaining high vaccination coverage and swiftly responding to reported Adverse Events Following Immunization in order to regain consumer confidence in the hepatitis B vaccine.

    Data on parenting practices and the use of violence in child rearing remain scarce worldwide, hindering prevention efforts. This study examines disciplinary methods used on children at home in Viet Nam. It is based on data collected from 2010 to 2011 through the fourth round of the Multiple Indicator Cluster Survey (MICS4)-a household survey program supported by the United Nations Children's Fund (UNICEF) that focuses on women and children in low- and middle-income countries. Respondents in the survey were asked 11 questions relating to disciplinary measures used in the preceding month on one randomly selected child (2-14 years old) in each household. A final question about attitudes probed adults' views on the need for physical punishment in child rearing. Univariate and multivariate analyses were conducted to estimate the prevalence of violent and nonviolent forms of discipline, and to identify risk factors associated with violent punishment. Results showed that three in four children in Viet Nam are disciplined through violent means. The exposure of Vietnamese children to violent forms of discipline was significantly associated with varied characteristics of both children and their caregivers. Moreover, the use of violent disciplinary practices on children was strongly associated with positive attitudes toward corporal punishment. Risk factors for violent child discipline identified in this study can inform future interventions to promote positive practices and to protect Vietnamese children against violence in the home.

    Full Text Available Hepatitis B (HBV infection is endemic in Viet Nam, with up to 8.4 million individuals estimated to be chronically infected. We describe results of a large, multicentre seroepidemiological and molecular study of the prevalence of HBV infection and blood-borne viral coinfections in Viet Nam. Individuals with varying risk factors for infection (n = 8654 were recruited from five centres; Ha Noi, Hai Phong, Da Nang, Khanh Hoa and Can Tho. A mean prevalence rate of 10.7% was observed and levels of HBsAg were significantly higher in injecting drug users (IDUs (17.4%, n = 174/1000 and dialysis patients (14.3%, n = 82/575 than in lower-risk groups (9.4%; p<0.001. Coinfection with HIV was seen in 28% of HBV-infected IDUs (n = 49/174 and 15.2% of commercial sex workers (CSWs; n = 15/99. HCV infection was present in 89.8% of the HBV-HIV coinfected IDUs (n = 44/49 and 40% of HBV-HIV coinfected CSWs (n = 16/40. Anti-HDV was detected in 10.7% (n = 34/318 of HBsAg positive individuals. Phylogenetic analysis of HBV S gene (n = 187 showed a predominance of genotype B4 (82.6%; genotypes C1 (14.6%, B2 (2.7% and C5 (0.5% were also identified. The precore mutation G1896A was identified in 35% of all specimens, and was more frequently observed in genotype B (41% than genotype C (3%; p<0.0001. In the immunodominant 'a' region of the surface gene, point mutations were identified in 31% (n = 58/187 of sequences, and 2.2% (n = 4/187 and 5.3% (n = 10/187 specimens contained the major vaccine escape mutations G145A/R and P120L/Q/S/T, respectively. 368 HBsAg positive individuals were genotyped for the IL28B SNP rs12979860 and no significant association between the IL28B SNP and clearance of HBsAg, HBV viral load or HBeAg was observed. This study confirms the high prevalence of HBV infection in Viet Nam and also highlights the significant levels of blood-borne virus coinfections, which have important implications for hepatitis-related morbidity and development of effective

    'Japan-Viet Nam Joint Statement on the Strategic Partnership for Peace and Prosperity in Asia' issued after the meeting between Japan-Viet Nam Prime Ministers on October 31, affirmed that the Vietnamese Government had decided to choose Japan as the cooperation partner for building Vinh Hai Unit 1 and 2 Project in the Ninh Thuan Province, southern Viet Nam, which showed substantially an order of Japan was arranged informally. 'International Nuclear Energy Development of Japan Co., Ltd. (JINED)' set up by industry and government, would negotiate to decide fundamental parameters such as type and power of nuclear power plants with the start of operation scheduled in 2021. This special issue consisted of six articles on significance of the project of Japan's first export, feasibility studies and future perspective and regional effects with introduction of nuclear power station in Viet Nam.

    2004-01-01

    There has been a decided lack of empirical research examining development aid agencies as 'agents of change' in environmental impact assessment (EIA) systems in developing countries, particularly research examining the model of environmental planning practice promoted by aid agencies as part of capacity building. This paper briefly traces a conceptual framework of EIA, then introduces the concept of 'EIA capacity building'. Using Viet Nam as a case study, the paper then outlines the empirical results of the research, focusing on the extent to which aid agency capacity-building programs promoted a Technical vs. Planning Model of EIA and on the coherence of capacity-building efforts across all aid programs. A discussion follows, where research results are interpreted within the Vietnamese context, and implications of research results are identified for three main groups of actors. The paper concludes by calling for development aid agencies to reconceptualise EIA capacity building as an opportunity to transform developing countries' development planning processes

    Dao Thanh Canh never studied physics or chemistry in school, but he understands a thing or two about nuclear isotopes. Until a couple of years ago, much of his five acre farm on the hills of central Viet Nam was gradually sliding away. Thanks to nuclear techniques used in determining the exact cause and source of soil erosion, his land is now stable, and his coffee plantation profitable. “We were very worried as uncertainty loomed,” he said. “A few centimetres of the soil disappeared every year when we had big hail storms.” Thanh Canh is not alone. Soil degradation affects 1.9 billion hectares of land worldwide, close to two thirds of global soil resources.

    Transmission of tuberculosis (TB) to health care workers (HCWs) is a global issue. Although effective infection control measures are expected to reduce nosocomial TB, HCWs' infection has not been assessed enough in TB high burden countries. We conducted a cross-sectional study to determine the prevalence of TB infection and its risk factors among HCWs in Hanoi, Viet Nam. A total of 300 HCWs including all staff members in a municipal TB referral hospital received an interferon-gamma release assay (IGRA), QuantiFERON-TB Gold In-Tube(TM), followed by one- and two-step tuberculin skin test (TST) and a questionnaire-based interview. Agreement between the tests was evaluated by kappa statistics. Risk factors for TB infection were analyzed using a logistic regression model. Among the participants aged from 20 to 58 years (median = 40), prevalence of TB infection estimated by IGRA, one- and two-step TST was 47.3%, 61.1% and 66.3% respectively. Although the levels of overall agreement between IGRA and TST were moderate, the degree of agreement was low in the group with BCG history (kappa = 0.29). Working in TB hospital was associated with twofold increase in odds of TB infection estimated by IGRA. Increased age, low educational level and the high body mass index also demonstrated high odds ratios of IGRA positivity. Prevalence of TB infection estimated by either IGRA or TST is high among HCWs in the hospital environment for TB care in Viet Nam and an infection control program should be reinforced. In communities with heterogeneous history of BCG vaccination, IGRA seems to estimate TB infection more accurately than any other criteria using TST.

    Full Text Available Abstract The findings of our research show that while police play multiple roles in the fight against drug-related crime, they often perceived their tasks – especially preventing and controlling drug use on the one hand, and supporting harm reduction on the other – as contradictory, and this creates tensions in their work and relations with their communities. Although they are leaders and implementers of harm reduction, not all police know about it, and some remain skeptical or perceive it as contradictory to their main task of fighting drugs. Methadone treatment is seen by some as in competition with their main task of coordinating conventional drug treatment in the rehabilitation center. The history of drug use and the evolution of discourses on drug use in Viet Nam have created these conflicting pressures on police, and thus created contradictory expectations and led to different views and attitudes of police regarding various harm reduction measures. This might aid understanding why, despite the comprehensive and progressive policies on HIV/AIDS and harm reduction in Viet Nam, it is not easy for police to actively and effectively support and be involved in harm reduction at the ground level. To promote the wider acceptance of harm reduction the concept of community safety must be expanded to include community health; harm reduction must be integrated into the “new society” movement; and laws and policies need further revision to reduce contradiction between current drug laws and HIV laws. Harm reduction guidelines for police and other actors need to be disseminated and supported, embodying better ways of working between sectors, and all sectors in the partnership require support for building capacity to contribute to the overall goal.

    Introduction Chronic diseases account for most of the disease burden in low- and middle-income countries, particularly those in Asia. We reviewed literature on chronic disease risk factors in Viet Nam to identify patterns and data gaps. Methods All population-based studies published from 2000 to 2012 that reported chronic disease risk factors were considered. We used standard chronic disease terminology to search PubMed and assessed titles, abstracts, and articles for eligibility for inclusion. We summarized relevant study information in tables listing available studies, risk factors measured, and the prevalence of these risk factors. Results We identified 23 studies conducted before 2010. The most common age range studied was 25 to 64 years. Sample sizes varied, and sample frames were national in 5 studies. A combination of behavioral, physical, and biological risk factors was studied. Being overweight or obese was the most common risk factor studied (n = 14), followed by high blood pressure (n = 11) and tobacco use (n = 10). Tobacco and alcohol use were high among men, and tobacco use may be increasing among Vietnamese women. High blood pressure is common; however, people’s knowledge that they have high blood pressure may be low. A high proportion of diets do not meet international criteria for fruit and vegetable consumption. Prevalence of overweight and obesity is increasing. None of the studies evaluated measured dietary patterns or total caloric intake, and only 1 study measured dietary salt intake. Conclusion Risk factors for chronic diseases are common in Viet Nam; however, more recent and context-specific information is required for planning and monitoring interventions to reduce risk factors and chronic disease in this country.

    Full Text Available Background: Since 1962, enterovirus D68 (EV-D68 has been implicated in multiple outbreaks and sporadic cases of respiratory infection worldwide, but especially in the USA and Europe with an increasing frequency between 2010 and 2014. We describe the detection, associated clinical features and molecular characterization of EV-D68 in central and southern Viet Nam between 2009 and 2015. Methods: Enterovirus/rhinovirus PCR positive respiratory or CSF samples taken from children and adults with respiratory/central nervous system infections in Viet Nam were tested by an EV-D68 specific PCR. The included samples were derived from 3 different observational studies conducted at referral hospitals across central and southern Viet Nam between 2009 and 2015. Whole-genome sequencing was carried out using a MiSeq based approach. Phylogenetic reconstruction and estimation of evolutionary rate and recombination were carried out in BEAST and Recombination Detection Program, respectively. Results: EV-D68 was detected in 21/625 (3.4% enterovirus/rhinovirus PCR positive respiratory samples but in none of the 15 CSF. All the EV-D68 patients were young children (age range: 11.8 – 24.5 months and had moderate respiratory infections. Phylogenetic analysis suggested that the Vietnamese sequences clustered with those from Asian countries, of which 9 fell in the B1 clade, and the remaining sequence was identified within the A2 clade. One intra sub-clade recombination event was detected, representing the second reported recombination within EV-D68. The evolutionary rate of EV-D68 was estimated to be 5.12E-3 substitutions/site/year. Phylogenetic analysis indicated that the virus was imported into Viet Nam in 2008. Conclusions: We have demonstrated for the first time EV-D68 has been circulating at low levels in Viet Nam since 2008, associated with moderate acute respiratory infection in children. EV-D68 in Viet Nam is most closely related to Asian viruses, and clusters

    Full Text Available Introducción: en la actualidad existe en los adolescentes una temprana iniciación de las relaciones sexuales y cambios en la actitud social hacia la sexualidad. Objetivo: identificar las particularidades y conocimientos sobre sexualidad en adolescentes. Métodos: se realizó una investigación descriptiva y transversal en adolescentes entre los 12 y 15 años, de la secundaria básica "Viet Nam" del municipio Arroyo Naranjo, durante los años 2009-2010. El universo estuvo constituido por 296 estudiantes y la muestra por 150, seleccionados mediante sorteo hasta completar 50 estudiantes de cada año. La información se obtuvo de una encuesta validada por el Ministerio de Educación. Todos los seleccionados expresaron su consentimiento para participar en la investigación. Resultados: predominó el sexo masculino y los adolescentes de 15 años. El inicio de las relaciones sexuales fue a los 14 años en los muchachos y a los 15 en las muchachas; 72 (56,69 % adolescentes utilizaron el condón en su "primera vez". Las principales vías de obtención de información fueron los padres, profesores y la información televisiva. Hubo mayor conocimiento sobre VIH-sida, gonorrea y sífilis y menor sobre, herpes simple y clamidia. El condón resultó ser el método anticonceptivo más conocido. Conclusiones: hay un inicio precoz en las relaciones sexuales y poco conocimiento acerca de los métodos anticonceptivos biológicos o naturales, lo que pudiera estar indicando la importancia que tiene la familia, sobre todo los padres, los profesores y médicos de familia, en incrementar y mantener la labor educativa con los jóvenes en relación con la sexualidad.Introduction: there exists an early onset of sexual relations in adolescents at present, together with changes in the social attitude towards sexuality.

    Viet Nam is experiencing a shift in its burden of disease profile with injuries becoming more prominent. A history of high alcohol involvement in road traffic crashes despite stringent laws led to increased enforcement by police, enhanced public education messaging and targeted social marketing campaigns in Ha Nam and Ninh Binh provinces in Viet Nam. This study aims to illustrate the changes in prevalence (November 2010 to December 2011) and knowledge, attitudes and practices (KAP) around alcohol use and drink-driving for the year 2011. Breath Alcohol Concentration (BrAC) was collected through police enforcement checkpoints in the two provinces. The proportion of drivers with BrAC above the legal limit was plotted over time for both provinces. The trend in prevalence of drink-driving over time was further assessed using Poisson regression models. Prevailing KAPs were determined through surveying randomly selected road users over the age of 17 years at gas stations at quarterly intervals. Cross tabulations of key variables as well Chi-Square statistic were used to assess associations. A total of 8,404 drivers were tested for BrAC levels of which less than 0.25% were female. Of 1,639 drivers displaying BrAC levels in excess of the legal limit, 87.3% were car drivers, 7.9% motorcyclists and 86% were between the ages of 25 and 44 years. KAP surveys captured 1,661 drivers over the study period. The prevalence of self-reported drink-driving increased 6 percentage points among respondents aged 27-36. Between 44% (January 2011) and 49% (December 2011) of respondents indicated awareness of a drinking and driving Blood Alcohol Concentration (BAC) or BrAC limit and only 25% of all study participants recalled being penalized for a traffic violation - none of which were for drink-driving. While there has been some reduction in drink-driving prevalence, inadequate or incorrect knowledge on drink-driving legislation appears to be an impediment to greater gains. Increased

    The aim of this study was to examine the relationships between psychological and social factors and late pregnancy IDA among pregnant women in rural Viet Nam. Pregnant women from 50 randomly-selected communes within Ha Nam province were recruited and assessed at 12 - 20 weeks gestation (Wave 1, W1). They were followed up in the last trimester (Wave 2, W2). IDA was defined as Haemoglobin Viet Nam. The link between them suggests that while direct recommendations to use iron supplements are important, the social factors associated with common mental disorders should be addressed in antenatal care in order to improve the health of pregnant women and their infants.

    District 6, An Hoa Clinic in Ho Chi Minh City (HCMC), Viet Nam. To evaluate the performance of various algorithms in tuberculosis (TB) screening and diagnosis in a human immunodeficiency virus (HIV) infected population in HCMC, Viet Nam. A cross-sectional study of 397 consecutive HIV-infected patients seeking care at the An Hoa Clinic from August 2009 to June 2010. Data on participant demographics, clinical status, chest radiography (CXR) and laboratory results were collected. A multiple logistic regression model was developed to assess the association of covariates and pulmonary TB (PTB). The prevalence of sputum culture-confirmed PTB, acid-fast bacilli (AFB) positive TB, and multidrugresistant TB among the 397 HIV-infected patients was respectively 7%, 2%, and 0.3%. Adjusted odds ratios for low CD4+ cell count, positive sputum smear, and CXR to positive sputum culture were respectively 3.17, 32.04 and 4.28. Clinical findings alone had poor sensitivity, but combining CD4+ cell count, AFB sputum smear and CXR had a more accurate diagnostic performance. Results suggest that symptom screening had poor clinical performance, and support the routine use of sputum culture to improve the detection of TB disease in HIV-infected individuals in Viet Nam. However, when routine sputum culture is not available, an algorithm combining CD4+ cell count, AFB sputum smear and CXR is recommended for diagnosing PTB.

    It is indicated that children are involuntarily exposed to secondhand smoke from adults, mainly at their home environment. This study aimed at describing the effectiveness of the school-based intervention to decrease the in-home smoking situation of adults so as to decrease children's exposure to secondhand smoke at home during the year 2011-2012 in a rural district in Hanoi, Viet Nam. This school-based intervention program (intervention and control group) involved 804 children aged 8 to 11 years from August 2011 to May 2012 in a rural district of Hanoi, Viet Nam. Children were taught in class about the harmful effects of secondhand smoke and about how to negotiate with fathers not to smoke in-home. Then children applied what they learnt, including staying away from secondhand smoke and persuading fathers not to smoke in-home in order to decrease children's exposure to secondhand smoke. Chi square test, t-test and multinominal logistic regression were applied in data analysis. The results showed that children's reported their father's in-home smoking decreased from 83.0% pre-intervention to 59.8% post-intervention ( p Viet Nam to increase children's awareness on the adverse health effects of secondhand smoke and to help them to be able to avoid their exposure to secondhand smoke at their home environment.

    The Red River is the second largest river in Viet Nam and constitutes the main water source for a large percentage of the population of North Viet Nam. Here we present the results of an annual survey of Escherichia coli (EC) and Total Coliforms (TC) in the Red River basin, North Viet Nam. The objective of this work was to obtain information on faecal indicator bacteria (FIB) numbers over an annual cycle and, secondly, to determine the die-off rates of these bacterial indicators. Monthly observations at 10 stations from July 2013-June 2014 showed that TC and EC reached as high as 39100 cfu (colony forming units) 100 ml-1 and 15300 colonies 100 ml-1, respectively. We observed a significant seasonal difference for TC (p < 0.05) with numbers being higher during the wet season. In contrast, no significant seasonal difference was found for EC. The FIB die-off rates ranged from 0.01 d-1 to a maximum of 1.13 d-1 for EC and from 0.17 d-1 to 1.33 d-1 for TC. Die-off rates were significantly higher for free bacteria than for total (free + particle attached) bacteria, suggesting that particle attachment provided a certain level of protection to FIB in this system.

    Land use changes are being interested in most countries, especially in developing countries. Because land use changes always impacts on sustainable development not only in a region or a country but also in whole the world. Viet Nam is a developing country, in the last 10 years, land uses have rapidly changed in most provinces. Many of agriculture areas, forest areas have changed for various purposes as urban sprawl, establishing new industrial parks, public areas, mining and other land uses relate to human activities or economic function associated with a specific piece of land. Beside efficiencies of economic and society, then environment issues have been threatening serious pollution, are from land use changes. Remote sensing images application on studying land use changes, has been done in many countries around the world, and has brought high efficiencies. However, this application is still very new and limited in Viet Nam due to lacking of materials, tools, experts of remote sensing. This study used spatial data as Landsat TM images, SPOT5 images and land use planning maps to rapidly assess on happenings of land uses in the period 2000 -2010 in Cong river basin (Thai Nguyen City, Viet Nam), and to forecast the changes of land uses in the period 2010 - 2020. The results had a good accuracy and to be important references for authorities, policy makers in local land use.

    Mortality statistics form a crucial component of national Health Management Information Systems (HMIS). However, there are limitations in the availability and quality of mortality data at national level in Viet Nam. This study assessed the completeness of recorded deaths and the reliability of recorded causes of death (COD) in the A6 death registers in the national routine HMIS in Viet Nam. 1477 identified deaths in 2014 were reviewed in two provinces. A capture-recapture method was applied to assess the completeness of the A6 death registers. 1365 household verbal autopsy (VA) interviews were successfully conducted, and these were reviewed by physicians who assigned multiple and underlying cause of death (UCOD). These UCODs from VA were then compared with the CODs recorded in the A6 death registers, using kappa scores to assess the reliability of the A6 death register diagnoses. The overall completeness of the A6 death registers in the two provinces was 89.3% (95%CI: 87.8-90.8). No COD recorded in the A6 death registers demonstrated good reliability. There is very low reliability in recording of cardiovascular deaths (kappa for stroke = 0.47 and kappa for ischaemic heart diseases = 0.42) and diabetes (kappa = 0.33). The reporting of deaths due to road traffic accidents, HIV and some cancers are at a moderate level of reliability with kappa scores ranging between 0.57-0.69 (pViet Nam.

    To report on the use of lot quality-assurance sampling (LQAS) surveys undertaken within an area-sampling framework to identify priority areas for intervention with trachoma control activities in Viet Nam. The LQAS survey method for the rapid assessment of the prevalence of active trachoma was adapted for use in Viet Nam with the aim of classifying individual communes by the prevalence of active trachoma among children in primary school. School-based sampling was used; school sites to be sampled were selected using an area-sampling approach. A total of 719 communes in 41 districts in 18 provinces were surveyed. Survey staff found the LQAS survey method both simple and rapid to use after initial problems with area-sampling methods were identified and remedied. The method yielded a finer spatial resolution of prevalence than had been previously achieved in Viet Nam using semiquantitative rapid assessment surveys and multistage cluster-sampled surveys. When used with area-sampling techniques, the LQAS survey method has the potential to form the basis of survey instruments that can be used to efficiently target resources for interventions against active trachoma. With additional work, such methods could provide a generally applicable tool for effective programme planning and for the certification of the elimination of trachoma as a blinding disease.

    During our epidemiological surveys for Paragonimus species in central Viet Nam, we found four morphologically different Paragonimus metacercariae in mountainous crabs. They were identified as metacercariae of Paragonimus westermani, P. bangkokensis, P. proliferus, and P. harinasutai in the order of their prevalence in crab hosts. This is the first discovery of P. harinasutai in Viet Nam, co-inhabiting with P. bangkokensis and other species. Metacercariae of P. harinasutai were given orally to a cat to obtain adult worms. Then, ITS2 and CO1 sequences of metacercariae and adults of P. harinasutai, and metacercariae of P. bangkokensis collected from the same place were determined for analyses of phylogenetic relationships to other P. harinasutai and P. bangkokensis populations as well as related species. The results of molecular analyses showed that P. harinasutai from Quang Binh province of central Viet Nam was almost completely identical with those from Vientiane, Lao PDR; P. bangkokensis from Quang Binh, Viet Nam was also almost completely identical with those from Lao PDR and from Quang Ninh province, Viet Nam. Except for one P. harinasutai isolate from China, all populations of P. harinasutai and P. bangkokensis from Thailand, Lao and Viet Nam make a single clade in both ITS2 and CO1 trees. In ITS2 sequences, AT deletion and ATC insertion were observed in some isolates of both species, indicating recent gene flow between P. harinasutai and P. bangkokensis. Moreover, because of their extremely high genetic similarities and their co-inhabitation in the same crab hosts found in Thailand, Lao PDR and Viet Nam, they should be considered as the sister species at the early stage of divergence. In addition, P. microrchis previously described from Yunnan, China should be placed as the synonym of P. harinasutai, because of their morphological and molecular similarities.

    This study was conducted during 1992 to 1994 with the objective of assessing genotypic differences in phosphorus use efficiency of wetland rice (Oriza sativa L.) and to select genotypes which grow well on soils low in available P or requiring only small amounts of added phosphorus fertilizer. In the first experiment, 24 genotypes of rice were screened under field conditions at low P (0 P added) and high P (90 kg P 2 O 5 /ha) on a gray soil of South Viet Nam. Significant genotypic differences were found in straw and grain yield, total P uptake, plant height and phosphorus use efficiency. Grain yield was highly correlated with phosphorus use efficiency. The effect of P supply was generally small. On average P supply decreased straw yield and increased grain yield. In the second experiment, four genotypes selected from the first experiment were grown under greenhouse conditions for four weeks supplied with 0, 30 and 90 ppm. Dry weight of shoots did not respond to P fertilization, but dry weight of roots increased with increasing P supply. The two efficient genotypes, G6 and G22, showed a higher root/shoot ratio than the two inefficient genotypes, G11 and G19. This indicates a higher potential for P acquisition of G6 and G22. In the third experiment, the same contrasting genotypes, and G18 with intermediate efficiency, were grown under field conditions at 0, 30, 60, 90 and 120 kg P 2 O 5 /ha. Of the two inefficient genotypes, G11 gave the highest grain yield at 60 and G19 at 90 kg P 2 O 5 /ha; G18 gave a clear response up to 60 kg P 2 O 5 /ha. Based on the information obtained in this study we conclude that G6 and G22 are efficiently and well adapted rice genotypes to gray soils of South Viet Nam, low in available P. At low P supply G6 may be slightly better than G22. Further, the 15 N tracer study showed that for G6, a small P supply (30 kg P 2 O 5 /ha) can increase the % N recover from urea applied at 120 kg N/ha. (author). 12 refs, 6 figs, 3 tabs

    Abstract Objective To establish the prevalence of common perinatal mental disorders their determinants, and their association with preventive health care use among women in one rural and one urban province in northern Viet Nam. Methods We conducted a cross-sectional survey of cohorts of pregnant women and mothers of infants recruited systematically in 10 randomly-selected communes. The women participated in psychiatrist-administered structured clinical interviews and separate structured interviews to assess sociodemographic factors, reproductive health, the intimate partner relationship, family violence and the use of preventive and psychiatric health care. Associations between these variables and perinatal mental disorders were explored through univariate analyses and multivariable logistic regression. Findings Among women eligible for the study (392), 364 (93%) were recruited. Of these, 29.9% (95% confidence interval, CI: 25.20–34.70) were diagnosed with a common perinatal mental disorder (CPMD). The frequency of such disorders during pregnancy and in the postpartum period was the same. Their prevalence was higher among women in rural provinces (odds ratio, OR: 2.17; 95% CI: 1.19–3.93); exposed to intimate partner violence (OR: 2.11; 95% CI: 1.12–3.96); fearful of other family members (OR: 3.36; 95% CI: 1.05–10.71) or exposed to coincidental life adversity (OR: 4.40; 95% CI: 2.44–7.93). Fewer women with a CPMD used iron supplements than women without a CPMD, but the results were not statistically significant (P = 0.05). None of the women studied had ever received mental health care. Conclusion Perinatal depression and anxiety are prevalent in women in northern Viet Nam. These conditions are predominantly determined by social factors, including rural residence, poverty and exposure to family violence. At present the needs of women with common perinatal mental disorders are unrecognized and not attended to and their participation in essential

    In Viet Nam, household direct out-of-pocket (OOP) health expenditure as a share of the total health expenditure has been always high, ranging from 50% to 70%. The high share of OOP expenditure has been linked to different inequity problems such as catastrophic health expenditure (households must reduce their expenditure on other necessities) and impoverishment. This paper aims to examine catastrophic and poverty impacts of household out-of-pocket health expenditure in Viet Nam over time and identify socio-economic indicators associated with them. Data used in this research were obtained from a nationally representative household survey, Viet Nam Living Standard Survey 2002, 2004, 2006, 2008 and 2010. The findings revealed that there were problems in health care financing in Viet Nam - many households encountered catastrophic health expenditure and/or were pushed into poverty due to health care payments. The issues were pervasive over time. Catastrophic expenditure and impoverishment problems were more common among the households who had more elderly people and those located in rural areas. Importantly, the financial protection aspect of the national health insurance schemes was still modest. Given these findings, more attention is needed on developing methods of financial protection in Viet Nam. Copyright © 2012 Elsevier Ltd. All rights reserved.

    To test the sensitivity and specificity of a clinical case definition of acute intussusception in infants to assist health-care workers in settings where diagnostic facilities are not available. Prospective studies were conducted at a major paediatric hospital in Viet Nam (the National Hospital of Pediatrics, Hanoi) from November 2002 to December 2003 and in Australia (the Royal Children's Hospital, Melbourne) from March 2002 to March 2004 using a clinical case definition of intussusception. Diagnosis of intussusception was confirmed by air enema or surgery and validated in a subset of participants by an independent clinician who was blinded to the participant's status. Sensitivity of the definition was evaluated in 584 infants agedclinical features consistent with intussusception but for whom another diagnosis was established (234 infants in Hanoi; 404 in Melbourne). In both locations the definition used was sensitive (96% sensitivity in Hanoi; 98% in Melbourne) and specific (95% specificity in Hanoi; 87% in Melbourne) for intussusception among infants with sufficient data to allow classification (449/533 in Hanoi; 50/51 in Melbourne). Reanalysis of patients with missing data suggests that modifying minor criteria would increase the applicability of the definition while maintaining good sensitivity (96-97%) and specificity (83-89%). The clinical case definition was sensitive and specific for the diagnosis of acute intussusception in infants in both a developing country and a developed country but minor modifications would enable it to be used more widely.

    This study examines the influence of social networks on the sexual relations of migrant construction workers in Ha Noi, Viet Nam. Research included observation and interviews with members of two different groups of workers. The first group, together with their employer (cai), came from the same village; the second group came from different villages. Of interest in the present study was how social relationships among workers and their employers influence extra-marital sexual activity. In the group where workers and their cai came from the same village of origin, fear of acquiring a bad reputation made these workers reluctant to seek sex services, since accounts of their behaviour were transmitted quickly home. In contrast, workers from the group who came from different villages often went out together to purchase sex. The absence of direct links to their villages of origin made it easier for these latter workers to conceal their activity. The implication of these findings for sexual safety and risk are discussed.

    In Viet Nam, an inactivated, mouse brain-derived vaccine for Japanese encephalitis (JE) has been given exclusively to ≤ 5 years old children in 3 paediatric doses since 1997. However, JE incidence remained high, especially among children aged 5-9 years. We conducted a model JE immunization programme to assess the feasibility and impact of JE vaccine administered to 1-9 year(s) children in 3 standard-dose regimen: paediatric doses for children aged <3 years and adult doses for those aged ≥ 3 years. Of the targeted children, 96.2% were immunized with ≥ 2 doses of the vaccine. Compared to the national immunization programme, JE incidence rate declined sharply in districts with the model programme (11.32 to 0.87 per 100,000 in pre-versus post-vaccination period). The rate of reduction was most significant in the 5-9 years age-group. We recommend a policy change to include 5-9 years old children in the catch-up immunization campaign and administer a 4th dose to those aged 5-9 years, who had received 3 doses of the vaccine during the first 2-3 years of life.

    Over 40 delegates attended the Indo-China Female Parliamentarians Conference on the Status of Women and Reproductive Health held in Viet Nam in June 1995. The conference was organized by the Vietnamese Association of Parliamentarians on Population and Development. Participants noted that, in Indochina, the participation of women in local politics has been blocked by the absence of laws and policies on gender equality. Recommended, to remedy this situation, were the following measures: 1) implementation of programs on women's status outlined at the 1994 International Conference on Population and Development; 2) allocation of sufficient resources for programs in the areas of maternal-child health, family planning, and acquired immunodeficiency syndrome (AIDS) prevention; 3) enactment of laws banning child prostitution and violence against women; 4) promotion of changes in men's sexual behaviors that spread AIDS; 5) encouragement of women to increase their knowledge of and participation in political action; and 6) appeals to international agencies and nongovernmental organizations to develop programs for Indochinese women.

    Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of padvertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

    Full Text Available The relationships between the infecting dengue serotype, primary and secondary infection, viremia and dengue severity remain unclear. This cross-sectional study examined these interactions in adult patients hospitalized with dengue in Ha Noi.158 patients were enrolled between September 16 and November 11, 2008. Quantitative RT-PCR, serology and NS1 detection were used to confirm dengue infection, determine the serotype and plasma viral RNA concentration, and categorize infections as primary or secondary. 130 (82% were laboratory confirmed. Serology was consistent with primary and secondary infection in 34% and 61%, respectively. The infecting serotype was DENV-1 in 42 (32%, DENV-2 in 39 (30% and unknown in 49 (38%. Secondary infection was more common in DENV-2 infections (79% compared to DENV-1 (36%, p<0.001. The proportion that developed dengue haemorrhagic fever (DHF was 32% for secondary infection compared to 18% for primary infection (p = 0.14, and 26% for DENV-1 compared to 28% for DENV-2. The time until NS1 and plasma viral RNA were undetectable was shorter for DENV-2 compared to DENV-1 (p≤0.001 and plasma viral RNA concentration on day 5 was higher for DENV-1 (p = 0.03. Plasma viral RNA concentration was higher in secondary infection on day 5 of illness (p = 0.046. We didn't find an association between plasma viral RNA concentration and clinical severity.Dengue is emerging as a major public health problem in Ha Noi. DENV-1 and DENV-2 were the prevalent serotypes with similar numbers and clinical presentation. Secondary infection may be more common amongst DENV-2 than DENV-1 infections because DENV-2 infections resulted in lower plasma viral RNA concentrations and viral RNA concentrations were higher in secondary infection. The drivers of dengue emergence in northern Viet Nam need to be elucidated and public health measures instituted.

    Groundnut (Arachis hypogaea L.) and soybean (Glycine max (L.) Mer.) are grown mainly on two types of soil in Viet Nam: coastal-sandy and upland-degraded soils. These soils are deficient in N, and considering that fertilizer N is not only costly to farmers but also a threat to the environment, it is important to maximize productivity by exploiting the ability of these legumes to fix N 2 symbiotically in their root nodules. We initiated programmes of breeding and selection to combine high N 2 fixation and high grain-yielding capacity. In the spring of 1992, breeding lines of groundnut and soybean were tested under greenhouse conditions for varietal differences in the capacity to fix N 2 using the acetylene reduction assay and the 15 N-dilution technique, with upland rice as reference plants. Varietal differences were found in nitrogenase activity, and percent N derived from fixation (%Ndfa) ranged from 11 to 63% for groundnut and from 9 to 79% for soybean. Field experiments in the autumn-winter season of 1992 again revealed significant varietal differences; %Ndfa ranged from 36 to 56% for groundnut and from 28 to 58% for soybean. Gamma-irradiated seeds of soybean were propagated in bulk from M 1 to M 4 . Five high-yielding mutant lines of both species were selected from the M 5 populations, and N 2 fixation was estimated using the 15 N-dilution technique. The average values for %Ndfa of the mutants were 55 and 57%, significant improvements over the parent-cultivar values of 25 and 29% for soybean and groundnut, respectively

    Full Text Available Srepok watershed plays an important role in Central Highland in Viet Nam. It impacts to developing social-economic conditions. Therefore, it is necessary to research elements which impact to natural resources in this watershed. The Soil and Water Assessment Tool (SWAT model and Geography Information System (GIS were used to simulate water discharge in the Srepok watershed. The objectives of the research were to apply GIS and SWAT model for simulation water discharge and then, we assessed land use change which impacted on water discharge in the watershed. The observed stream flow data from Ban Don Stream gauge station was used to calibrate for the period from 1981 to 2000 and then validate for the period from 2001 to 2009. After using SWAT-CUP software to calibration, NSI reached 0.63 and R square value achieved 0.64 from 2004 to 2008 in calibration and NSI gained good level at 0.74 and R square got 0.75 from 2009 to 2012 in validation step at Ban Don Station. After that, land cover in 2010 was processed like land cover in 2000 and set up SWAT model again. The simulated water discharge in scenario 1 (land use 2000 was compared with scenario 2 (land use 2010, the simulation result was not significant difference between two scenarios because the change of area of land use was not much enough to affect the fluctuation of water discharge. However, the effect of land cover on water resource could be seen clearly via total water yield. The percentage of surface flow in 2000 was twice times more than in 2010; retard and base flow in 2000 was slightly more than in 2010. Therefore, decreased surface flow, increased infiltration capacity of water and enriched base flow resulted in the growth of land cover.

    Flooding is one of the most dangerous natural disasters in Vietnam. Floods have caused serious damages to people and made adverse impact on social economic development across the country, especially in lower river basin where there is high risk of flooding as consequences of the climate change and social activities. This paper presents a collaborative platform of a combination of an interactive web-GIS framework and a multi-criteria evaluation (MCE) tool. MCE is carried out in server side through web interface, in which parameters used for evaluation are groups into three major categories, including (1) climatic factor: precipitation, typhoon frequency, temperature, humidity (2) physiographic data: DEM, topographic wetness index, NDVI, stream power index, soil texture, distance to river (3) social factor: NDBI, land use pattern. Web-based GIS is based on open-source technology that includes an information page, a page for MCE tool that users can interactively alter parameters in flood susceptible mapping, and a discussion page. The system is designed for local participation in prediction of the flood risk magnitude under impacts of natural processes and human intervention. The proposed flood susceptibility assessment prototype was implemented in the Mekong river basin, Viet Nam. Index images were calculated using Landsat data, and other were collected from authorized agencies. This study shows the potential to combine web-GIS and spatial analysis tool to flood hazard risk assessment. The combination can be a supportive solution that potentially assists the interaction between stakeholders in information exchange and in disaster management, thus provides for better analysis, control and decision-making.

    Although psychoeducation has been found effective for improving the life functioning of patients with schizophrenia in high income countries, there have been relatively few studies of schizophrenia psychoeducation adapted for low and middle-income countries (LMIC), particularly in Southeast Asia. The present study assessed effects of the Family Schizophrenia Psychoeducation Program (FSPP) among Vietnamese patients and their families on the patients' (1) quality of life and (2) medication non-compliance, and the family and patients' (3) stigma towards schizophrenia, and (4) consumer satisfaction. This intervention study involved 59 patients, and their families, from the Da Nang Psychiatric Hospital, randomly assigned to treatment (n=30) or control (n=29) conditions. Control subjects received services as usual (antipsychotic medication); treatment group subjects received the FSPP as well. Blind-rater assessments were conducted at T1 immediately after project enrollment (prior to participating in the FSPP) and at T2 six months later. There were significant treatment effects on: (1) quality of life, (2) stigma, (3) medication compliance, and (4) consumer satisfaction, with all effects favoring the treatment group. Effect sizes were moderate to large. This psychoeducation program appears to reduce stigma, improve quality of life and medication compliance, and increase consumer satisfaction of Vietnamese patients with schizophrenia and their families, beyond the effects of antipsychotic medication. It involves relatively little cost, and it may be useful for it or equivalent programs to be implemented in other hospitals in Viet Nam, and potentially other low-income Asian countries to improve the lives of patients with schizophrenia.

    Fathers have an important but often neglected role in the promotion of healthy breastfeeding practices in developing countries. A community-based education intervention was designed to mobilize fathers' support for early breastfeeding. This study aimed to evaluate an education intervention targeting fathers to increase the proportion of early breastfeeding initiation and to reduce prelacteal feeding. Quasi-experimental study design was used to compare intervention and control areas located in two non-adjacent rural districts that shared similar demographic and health service characteristics in northern Viet Nam. Fathers and expectant fathers with pregnant wives from 7 to 30 weeks gestational age were recruited. Fathers in the intervention area received breastfeeding education materials, counselling services at a commune health centre and household visits. They were also invited to participate in a breastfeeding promotion social event. After intervention, early breastfeeding initiation rate was 81.2% in the intervention area and 39.6% in the control area (P < 0.001). Babies in the intervention area were more likely to be breastfed within the first hour after birth [odds ratio (OR) 7.64, 95% confidence interval (CI) 4.81-12.12] and not to receive any prelacteal feeding (OR 4.43, 95% CI 2.88-6.82) compared with those in the control area. Fathers may positively influence the breastfeeding practices of mothers, and as a resource for early childcare, they can be mobilized in programmes aimed at improving the early initiation of breastfeeding. © 2015 John Wiley & Sons Ltd.

    Hanoi Lung Hospital, Hanoi, Viet Nam. To compare the accuracy of CellScopeTB, a manually operated mobile digital fluorescence microscope, with conventional microscopy techniques. Patients referred for sputum smear microscopy to the Hanoi Lung Hospital from May to September 2013 were included. Ziehl-Neelsen (ZN) smear microscopy, conventional light-emitting diode (LED) fluorescence microscopy (FM), CellScopeTB-based LED FM and Xpert(®) MTB/RIF were performed on sputum samples. The sensitivity and specificity of microscopy techniques were determined in reference to Xpert results, and differences were compared using McNemar's paired test of proportions. Of 326 patients enrolled, 93 (28.5%) were Xpert-positive for TB. The sensitivity of ZN microscopy, conventional LED FM, and CellScopeTB-based LED FM was respectively 37.6% (95%CI 27.8-48.3), 41.9% (95%CI 31.8-52.6), and 35.5% (95%CI 25.8-46.1). The sensitivity of CellScopeTB was similar to that of conventional LED FM (difference -6.5%, 95%CI -18.2 to 5.3, P = 0.33) and ZN microscopy (difference -2.2%, 95%CI -9.2 to 4.9, P = 0.73). The specificity was >99% for all three techniques. CellScopeTB performed similarly to conventional microscopy techniques in the hands of experienced TB microscopists. However, the sensitivity of all sputum microscopy techniques was low. Options enabled by digital microscopy, such as automated imaging with real-time computerized analysis, should be explored to increase sensitivity.

    Full Text Available Abstract Background Seeking and utilisation of HIV prevention, treatment, care, and support services for people living with HIV is often hampered by HIV-related stigma. The study aimed to explore the perceptions and experiences regarding treatment, care, and support amongst people living with HIV in Viet Nam, where the HIV epidemic is concentrated among injecting drug users, sex workers, and men who have sex with men. Methods In-depth interviews and focus group discussions were conducted during September 2007 in 6 districts in Hai Phong with a very high HIV prevalence among injecting drug users. The information obtained was analysed and merged within topic areas. Illustrative quotes were selected. Results Stigma and discrimination against people living with HIV in the community and healthcare settings was commonly reported, and substantially hampered the seeking and the utilisation of HIV-related services. The informants related the high level of stigma to the way the national HIV preventive campaigns played on fear, by employing a “scare tactic” mainly focusing on drug users and sex workers, who were defined as “social evils” in the anti-drug and anti-prostitution policy. There was a strong exclusion effect caused by the stigma, with serious implications, such as loss of job opportunities and isolation. The support and care provided by family members was experienced as vital for the spirit and hope for the future among people living with HIV. Conclusions A comprehensive care and support programme is needed. The very high levels of stigma experienced seem largely to have been created by an HIV preventive scare tactic closely linked to the “social evil“ approach in the national policy on drug and prostitution. In order to reduce the stigma and create more effective interventions, this tactic will have to be replaced with approaches that create better legal and policy environments for drug users and sex workers.

    To evaluate the prevalence of and risk factors for allergen sensitisation among patients with chronic respiratory disease (CRD) in southern Viet Nam. An environmental questionnaire and skin prick tests for airborne and food allergens were administered to patients with CRD, defined as individuals with respiratory symptoms and lung function defects. Of 610 CRD patients, 56% had chronic obstructive pulmonary disease and 31% were asthma patients; 80% were males. The most frequent sensitisers were dust mites (Dermatophagoides farinae 22%, Blomia tropicalis 19%, D. pteronyssinus 18%) and cockroach droppings (13%). Among study participants, 37% were from rural settings and 36% from urban areas, whereas 27% had migrated from rural to urban areas. Compared with people from rural areas, being born in an urban area was a risk factor for sensitisation to mites (OR 1.56, 95%CI 1.11-2.20, P Viet Nam. Compared with the urban population, being native to a rural area was protective against mite sensitisation, but this effect ceased to be significant after migration from rural to urban areas.

    2013-02-01

    Wylie, McAllister, Davidson, and Marshall (2013) argue that recommendations made within the World Report on Disability provide an opportunity for speech-language pathologists to consider new ways of developing services for people with communication and swallowing disorders. They propose that current approaches to the delivery of speech-language pathology services are largely embedded within the medical model of impairment, thereby limiting the ability of services to meet the needs of people in a holistic manner. In this paper, the criticality of selecting an appropriate service delivery model is discussed within the context of a recently established post-graduate speech therapy education programme in Viet Nam. Driving forces for the implementation of the program will be explored, as will the factors that determined the choice of service delivery. Opportunities and challenges to the long-term viability of the program and the program's potential to meet the needs of persons with communication and swallowing disorders in Viet Nam will be considered.

    To compare estimated prevalence of head injuries among road traffic injury patients admitted to hospitals, before and after the introduction of a mandatory helmet law in the Socialist Republic of Viet Nam. Before and after study of all road traffic injury patients with head injuries admitted to 20 provincial and central hospitals 3 months before and after the new law came into effect on 15 December 2007. Relative risk was computed and comparison made for the periods of 3 months before and after the new law. The study found a 16 percent reduction in the risk of road traffic head injuries (4683 to 3522; relative risk [RR] 0.84; 95% confidence interval [CI] 0.81-0.87) and an 18 percent reduction in the risk of road traffic death (deaths in hospital plus injured patients discharged to die at home; 566 to 417; RR 0.82; 95% CI 0.73-0.93). Over the first 3 months of the comprehensive mandatory helmet legislation there has been a significant reduction in the risk of road traffic head injuries among patients admitted to 20 hospitals. The Viet Nam Government's decision to require all motorcycle riders and passengers to wear helmets is suspected of leading to positive road safety benefits and should be seen as a policy example for other low- and middle-income countries with a high utilization of motorcycles for transport.

    Full Text Available Infectious diseases of the central nervous system (CNS remain common and life-threatening, especially in developing countries. Knowledge of the aetiological agents responsible for these infections is essential to guide empiric therapy and develop a rational public health policy. To date most data has come from patients admitted to tertiary referral hospitals in Asia and there is limited aetiological data at the provincial hospital level where most patients are seen.We conducted a prospective Provincial Hospital-based descriptive surveillance study in adults and children at thirteen hospitals in central and southern Viet Nam between August 2007-April 2010. The pathogens of CNS infection were confirmed in CSF and blood samples by using classical microbiology, molecular diagnostics and serology.We recruited 1241 patients with clinically suspected infection of the CNS. An aetiological agent was identified in 640/1241 (52% of the patients. The most common pathogens were Streptococcus suis serotype 2 in patients older than 14 years of age (147/617, 24% and Japanese encephalitis virus in patients less than 14 years old (142/624, 23%. Mycobacterium tuberculosis was confirmed in 34/617 (6% adult patients and 11/624 (2% paediatric patients. The acute case fatality rate (CFR during hospital admission was 73/617 (12% in adults and to 42/624 (7% in children.Zoonotic bacterial and viral pathogens are the most common causes of CNS infection in adults and children in Viet Nam.

    Background. Penicillium marneffei is an important human immunodeficiency virus (HIV)–associated opportunistic pathogen in Southeast Asia. The epidemiology and the predictors of penicilliosis outcome are poorly understood. Methods. We performed a retrospective study of culture-confirmed incident penicilliosis admissions during 1996–2009 at the Hospital for Tropical Diseases in Ho Chi Minh City, Viet Nam. Seasonality of penicilliosis was assessed using cosinor models. Logistic regression was used to assess predictors of death or worsening disease based on 10 predefined covariates, and Cox regression was performed to model time-to-antifungal initiation. Results. A total of 795 patients were identified; hospital charts were obtainable for 513 patients (65%). Cases increased exponentially and peaked in 2007 (156 cases), mirroring the trends in AIDS admissions during the study period. A highly significant seasonality for penicilliosis (P Viet nam. The number of cases increases during rainy months. Injection drug use, shorter history, absence of fever or skin lesions, respiratory difficulty, higher lymphocyte count, and lower platelet count predict poor in-hospital outcome. PMID:21427403

    This study aimed at understanding the patterns of the utilization of prenatal diagnostic (PND) services among pregnant women, their satisfaction and its associated factors at three regional prenatal diagnostic centres in Viet Nam. A cross-sectional design was used, with a consecutive sampling method to recruit pregnant women who used PND services at the three biggest regional PND services centres in Viet Nam between January and June, 2014. A total of 298 participants, about 100 participants per centre were interviewed and included in data analysis. Descriptive analyses and logistic regression methods were applied to identify association between satisfaction of women and their socio-economic characteristics. 80% of pregnant women received counselling on PND services, whilst 90% received ultrasonography services; 65.4% were satisfied with the PND services they used. Pregnant women, who were in a lower income group and received counselling but did not receive ultrasonography, were more likely to have higher satisfaction levels of PND services. A process to ensure that every pregnant woman receives sufficient PND counselling before and after receiving PND testing must be given careful and thorough consideration.

    Men who have sex with men in Viet Nam have been under-studied as a high-risk group for HIV infection, and this population's percentage and determinants of HIV testing have not been comprehensively investigated. A national Internet-based survey of self-reported sexual and health seeking behaviours was conducted between August and October 2011 with 2077 Vietnamese men who had sex with men in the last twelve months to identify the frequency of 'never testing for HIV' among Internet-using MSM living in Viet Nam, as well as the factors associated with this HIV-related high-rish behavior. Logistic regression analyses were conducted to assess the demographic characteristics and behaviours predicting never testing for HIV. A total of 76.5% of men who have sex with men who were surveyed reported never having been voluntarily tested for HIV. Predictors of never being tested included having a monthly income less than VND 5 Million, being a student, using the Internet less than 15 hour per week, and not participating in a behavioural HIV intervention. Never testing for HIV is common among Internet-using men who have sex with men in Viet Nam. Given the dangerously high prevalence of this high-risk behaviour, our findings underscore the urgent need for segmented and targeted HIV prevention, care and treatment strategies, focusing on drastically reducing the number of men who have sex with men never testing for HIV in Viet Nam.

    Abstract Objective To establish iodine status among pregnant women in rural northern Viet Nam and explore psychosocial predictors of the use of iodized salt in their households. Methods This prospective study included pregnant women registered in health stations in randomly-selected communes in Ha Nam province. At recruitment ( 28 weeks of gestation) a urine specimen was collected to measure urinary iodine concentration (UIC) and iodized salt use was assessed. Predictors were explored through univariable analyses and multivariable linear and logistic regression. Findings The 413 pregnant women who provided data for this study had a median UIC of 70 µg/l; nearly 83% had a UIC lower than the 150 µg/l recommended by the World Health Organization; only 73.6% reported using iodized salt in any form in their households. Iodized salt use was lower among nulliparous women (odds ratio, OR: 0.56; 95% confidence interval, CI: 0.32–0.96); less educated women (OR: 0.34; 95% CI: 0.16–0.71); factory workers or small-scale traders (OR: 0.52; 95% CI: 0.31–0.86), government workers (OR: 0.35; 95% CI: 0.13–0.89) and women with common mental disorders at recruitment (OR: 0.61; 95% CI: 0.38–0.98). Conclusion The decline in the use of iodized salt in Viet Nam since the National Iodine Deficiency Disorders Control Programme was suspended in 2005 has placed pregnant women and their infants in rural areas at risk of iodine deficiency disorders.

    Full Text Available INTRODUCTION: Resistance of Mycobacterium tuberculosis (MTB to anti-tuberculosis (TB drugs presents a serious challenge to TB control worldwide. We investigated the status of drug resistance, including multidrug-resistant (MDR TB, and possible risk factors among newly diagnosed TB patients in Hanoi, the capital of Viet Nam. METHODS: Clinical and epidemiological information was collected from 506 newly diagnosed patients with sputum smear- and culture-positive TB, and 489 (96.6% MTB isolates were subjected to conventional drug susceptibility testing, spoligotyping, and 15-locus variable numbers of tandem repeats typing. Adjusted odds ratios (aORs were calculated to analyze the risk factors for primary drug resistance. RESULTS: Of 489 isolates, 298 (60.9% were sensitive to all drugs tested. Resistance to isoniazid, rifampicin, streptomycin, ethambutol, and MDR accounted for 28.2%, 4.9%, 28.2%, 2.9%, and 4.5%, respectively. Of 24 isolates with rifampicin resistance, 22 (91.7% were MDR and also resistant to streptomycin, except one case. Factors associated with isoniazid resistance included living in old urban areas, presence of the Beijing genotype, and clustered strains [aOR = 2.23, 95% confidence interval (CI 1.15-4.35; 1.91, 1.18-3.10; and 1.69, 1.06-2.69, respectively. The Beijing genotype was also associated with streptomycin resistance (aOR = 2.10, 95% CI 1.29-3.40. Human immunodeficiency virus (HIV coinfection was associated with rifampicin resistance and MDR (aOR = 5.42, 95% CI 2.07-14.14; 6.23, 2.34-16.58, respectively. CONCLUSION: Isoniazid and streptomycin resistance was observed in more than a quarter of TB patients without treatment history in Hanoi. Transmission of isoniazid-resistant TB among younger people should be carefully monitored in urban areas, where Beijing strains and HIV coinfection are prevalent.

    Full Text Available It is indicated that children are involuntarily exposed to secondhand smoke from adults, mainly at their home environment. This study aimed at describing the effectiveness of the school-based intervention to decrease the in-home smoking situation of adults so as to decrease children’s exposure to secondhand smoke at home during the year 2011–2012 in a rural district in Hanoi, Viet Nam. This school-based intervention program (intervention and control group involved 804 children aged 8 to 11 years from August 2011 to May 2012 in a rural district of Hanoi, Viet Nam. Children were taught in class about the harmful effects of secondhand smoke and about how to negotiate with fathers not to smoke in-home. Then children applied what they learnt, including staying away from secondhand smoke and persuading fathers not to smoke in-home in order to decrease children’s exposure to secondhand smoke. Chi square test, t-test and multinominal logistic regression were applied in data analysis. The results showed that children’s reported their father’s in-home smoking decreased from 83.0% pre-intervention to 59.8% post-intervention (p < 0.001 in the intervention school while no change happened in the control school. The study found that the better changed smoking location of adult smokers as reported by children associated with the school who received intervention activities (adjusted OR = 2.04; 95% CI: 1.28–3.24. Poorer changed attitudes towards secondhand smoke of children associated with a lower percentage of better change in smoking location of their fathers/other adult smokers (aOR = 0.51, 95% CI: 0.28–0.96. Children’s poorer changed knowledge towards secondhand smoke also associated with poorer changed smoking location of adult smokers (aOR = 2.88, 95% CI: 1.07–7.76. It is recommended by this study that similar school based intervention approaches should be applied in primary schools in Viet Nam to increase children’s awareness on the

    Industrial vegetable oil production in Viet Nam depends on oil seeds and crude plant oils that are currently more than 90% imported. As the first step in investigating the feasibility of using microalgae to provide Viet Nam with a domestic source of oil for food and edible oil industries, fifty lipid-producing microalgae were isolated and characterized. The microalgae were isolated from water sources ranging from freshwater to brackish and marine waters from a wide geographic distribution in Viet Nam. Initial analyses showed that 20 of the 50 strains had good growth rates, produced high biomass and had high lipid content, ranging up to 50% of dry weight biomass. 18S rRNA gene sequence analyses of the 50 strains showed a great diversity in this assemblage of microalgae, comprising at least 38 species and representatives of 25 genera : Chlamydomonas , Poterioochromonas , Scenedesmus , Desmodesmus , Chlorella , Bracteacoccus , Monoraphidium , Selenastrum , Acutodesmus , Mychonastes , Ankistrodesmus , Kirchneriella , Raphidocelis , Dictyosphaerium , Coelastrella , Schizochlamydella , Oocystidium , Nannochloris , Auxenochlorella , Chlorosarcinopsis , Stichococcus , Picochlorum , Prasinoderma , Chlorococcum , and Marvania. Some of the species are closely related to well-known lipid producers such as Chlorella sorokiniana , but some other strains are not closely related to the strains found in public sequence databases and likely represent new species. Analysis of oil quality showed that fatty acid profiles of the microalgal strains were very diverse and strain-dependent. Fatty acids in the microalgal oils comprised saturated fatty acids (SFAs), poly-unsaturated fatty acids (PUFAs), and mono-unsaturated fatty acids (MUFAs). The main SFA was palmitic acid. MUFAs and PUFAs were dominated by oleic acid, and linoleic and linolenic acids, respectively. Some strains were especially rich in the essential fatty acid α-linolenic acid (ALA), which comprised more than 20% of the

    Full Text Available Abstract Background The Plasmodium falciparum NA+/H+ exchanger (pfnhe1, gene PF13_0019 has recently been proposed to influence quinine (QN susceptibility. However, its contribution to QN resistance seems to vary geographically depending on the genetic background of the parasites. Here, the role of this gene was investigated in in vitro QN susceptibility of isolates from Viet Nam. Method Ninety-eight isolates were obtained from three different regions of the Binh Phuoc and Dak Nong bordering Cambodia provinces during 2006-2008. Among these, 79 were identified as monoclonal infection and were genotyped at the microsatellite pfnhe1 ms4760 locus and in vitro QN sensitivity data were obtained for 51 isolates. Parasite growth was assessed in the field using the HRP2 immunodetection assay. Results Significant associations were found between polymorphisms at pfnhe1 microsatellite ms4760 and susceptibility to QN. Isolates with two or more DNNND exhibited much lower susceptibility to QN than those harbouring zero or one DNNND repeats (median IC50 of 682 nM versus median IC50 of 300 nM; p = 0.0146 while isolates with one NHNDNHNNDDD repeat presented significantly reduced QN susceptibility than those who had two (median IC50 of 704 nM versus median IC50 of 375 nM; p pfcrt76T and wild-type pfmdr1 (> 95% thus preventing analysis of associations with these mutations. Interestingly, area with the highest median QN IC50 showed also the highest percentage of isolates carrying the pfnhe1 haplotype 7. Conclusions The haplotype 7 which is the typical Asian profile is likely well-adapted to high drug pressure in this area and may constitute a good genetic marker to evaluate the dissemination of QNR in this part of the world.

    Viet Nam does not have a system for the national collection of death data that meets international requirements for mortality reporting. It is identified as a 'no-report' country by the WHO. Verbal autopsy reports are used in the community but exclude deaths in hospitals. This project was undertaken in Bach Mai National General Hospital and Viet Duc Surgical and Trauma Hospital in Viet Nam from 1 March 2013 to 31 March 2015. In phase 1, a modified hospital death report form, consistent with the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, was developed. Small group training in use of the report form was delivered to 427 doctors. In phase two, death data were collected, collated and analysed. In phase three, a random sample (7%) of all report forms was checked for accuracy and completeness against medical records. During the 23 months of the study, 3956 deaths were recorded. Across both hospitals, 222 distinct causes of deaths were recorded. Traumatic cerebral oedema was the immediate cause of death (15% of cases, 575/3956 patients), followed by septic shock (13%, 528/3956), brain compression (11%, 416/3956), intracerebral haemorrhage (8%, 336/3956) and pneumonia (5%, 186/3956); 67% (2639/3956) of patients were discharged home to die and 33% (1314/3956) of deaths were due to a road traffic accident, or injury at home or at work. This study confirms the viability of implementing a death report form system compliant with international standards in hospitals in Viet Nam and provides the foundation for introducing a national death report form scheme. These data are critical to comprehensive knowledge of causes of death in Viet Nam. Death data about patients discharged home to die is presented for the first time, with implications for countries where this is a cultural preference.

    Enterovirus 71 (EV71)-associated hand, foot and mouth disease has emerged as a serious public health problem in South East Asia over the last decade. To better understand the prevalence of EV71 infection, we determined EV71 seroprevalence and seroincidence amongst healthy infants and children in Ho Chi Minh City, Viet Nam. In a cohort of 200 newborns, 55% of cord blood samples contained EV71 neutralizing antibodies and these decayed to undetectable levels by 6 months of age in 98% of infants. The EV71 neutralizing antibody seroconversion rate was 5.6% in the first year and 14% in the second year of life. In children 5–15 yrs of age, seroprevalence of EV71 neutralizing antibodies was 84% and in cord blood it was 55%. Taken together, these data suggest EV71 force of infection is high and highlights the need for more research into its epidemiology and pathogenesis in high disease burden countries. PMID:21765891

    The main objective of this pilot study, conducted in June 2015 in the Can Gio Mangrove Biosphere Reserve (Can Gio MBR, Viet Nam), was to develop an interdisciplinary approach to assess some key services provided by reforested mangroves subject to external pressures and varying management policies. We focused on the abundance of viruses, bacteria, endo- and epi- and macrofauna and the diversity of crabs in the mangrove and the exploitation of its resources. The main social finding was that the local inhabitants are aware of the levels of protection of the different zones within the Can Gio MBR and respect them. The core and the buffer zones seem to present a similar ecological status. Genotyping showed a low level of crab diversity although there were many different morphotypes. In the future, we need to understand the stakeholders' general perception of the biodiversity and environment changes by developing an integrated, multi-scale approach.

    Linking community knowledge with modern techniques to record and analyse risk related data is one way of engaging and mobilising community capacity. This paper discusses the use of the Geographic Information System (GIS) at the local level and the need for integrating modern technology and indigenous knowledge into disaster management. It suggests a way to mobilise available human and technical resources in order to strengthen a good partnership between local communities and local and national institutions. The paper also analyses the current vulnerability of two communes by correlating hazard risk and loss/damage caused by disasters and the contribution that domestic risk maps in the community can make to reduce this risk. The disadvantages, advantages and lessons learned from the GIS flood risk mapping project are presented through the case study of the Quang Tho Commune in Thua Thien Hue province, central Viet Nam.

    Enteroviruses are the most common causative agents of human illness. Enteroviruses have been associated with regional and global epidemics, recently, including with severe disease (Enterovirus A71 and D68), and are of interest as emerging viruses. Here, we typed Enterovirus A-D (EV) from central nervous system (CNS) and respiratory infections in Viet Nam. Data and specimens from prospective observational clinical studies conducted between 1997 and 2010 were used. Species and serotypes were determined using type-specific RT-PCR and viral protein 1 or 4 (VP1, VP4) sequencing. Samples from patients with CNS infection (51 children - 10 CSF and 41 respiratory/rectal swabs) and 28 adults (28 CSF) and respiratory infection (124 children - 124 respiratory swabs) were analysed. Twenty-six different serotypes of the four Enterovirus species (A-D) were identified, including EV-A71 and EV-D68. Enterovirus B was associated with viral meningitis in children and adults. Hand, foot and mouth disease associated Enteroviruses A (EV-A71 and Coxsackievirus [CV] A10) were detected in children with encephalitis. Diverse serotypes of all four Enterovirus species were found in respiratory samples, including 2 polio-vaccine viruses, but also 8 CV-A24 and 8 EV-D68. With the exception of EV-D68, the relevance of these viruses in respiratory infection remains unknown. We describe the diverse spectrum of enteroviruses from patients with CNS and respiratory infections in Viet Nam between 1997 and 2010. These data confirm the global circulation of Enterovirus genera and their associations and are important for clinical diagnostics, patient management, and outbreak response.

    Estimation of the size of populations at risk of HIV is a key activity in the surveillance of the HIV epidemic. The existing framework for considering future research needs may provide decision-makers with a basis for a fair process of deciding on the methods of the estimation of the size of key populations at risk of HIV. This study explores the extent to which stakeholders involved with population size estimation agree with this framework, and thus, the study updates the framework. We conducted 16 in-depth interviews with key informants from city and provincial governments, NGOs, research institutes, and the community of people at risk of HIV. Transcripts were analyzed and reviewed for significant statements pertaining to criteria. Variations and agreement around criteria were analyzed, and emerging criteria were validated against the existing framework. Eleven themes emerged which are relevant to the estimation of the size of populations at risk of HIV in Viet Nam. Findings on missing criteria, inclusive participation, community perspectives and conflicting weight and direction of criteria provide insights for an improved framework for the prioritization of population size estimation methods. The findings suggest that the exclusion of community members from decision-making on population size estimation methods in Viet Nam may affect the validity, use, and efficiency of the evidence generated. However, a wider group of decision-makers, including community members among others, may introduce diverse definitions, weight and direction of criteria. Although findings here may not apply to every country with a transitioning economy or to every emerging epidemic, the principles of fair decision-making, value of community participation in decision-making and the expected challenges faced, merit consideration in every situation.

    Since 2000, the Government of Viet Nam has committed to provide rural communities with increased access to safe water through a variety of household water supply schemes (wells, ferrocement tanks and jars) and piped water schemes. One possible, unintended consequence of these schemes is the concomitant increase in water containers that may serve as habitats for dengue mosquito immatures, principally Aedes aegypti. To assess these possible impacts we undertook detailed household surveys of Ae. aegypti immatures, water storage containers and various socioeconomic factors in three rural communes in southern Viet Nam. Positive relationships between the numbers of household water storage containers and the prevalence and abundance of Ae. aegypti immatures were found. Overall, water storage containers accounted for 92-97% and 93-96% of the standing crops of III/IV instars and pupae, respectively. Interestingly, households with higher socioeconomic levels had significantly higher numbers of water storage containers and therefore greater risk of Ae. aegypti infestation. Even after provision of piped water to houses, householders continued to store water in containers and there was no observed decrease in water storage container abundance in these houses, compared to those that relied entirely on stored water. These findings highlight the householders' concerns about the limited availability of water and their strong behavoural patterns associated with storage of water. We conclude that household water storage container availability is a major risk factor for infestation with Ae. aegypti immatures, and that recent investment in rural water supply infrastructure are unlikely to mitigate this risk, at least in the short term.

    To describe the use of episiotomy among Vietnamese-born women in Australia, including risk factors for, and pregnancy outcomes associated with, episiotomy. This population-based, retrospective cohort study included data on 598 305 singleton, term (i.e. ≥ 37 weeks' gestation) and vertex-presenting vaginal births between 2001 and 2010. Data were obtained from linked, validated, population-level birth and hospitalization data sets. Contingency tables and multivariate analysis were used to compare risk factors and pregnancy outcomes in women who did or did not have an episiotomy. The episiotomy rate in 12 208 Vietnamese-born women was 29.9%, compared with 15.1% in Australian-born women. Among Vietnamese-born women, those who had an episiotomy were significantly more likely than those who did not to be primiparous, give birth in a private hospital, have induced labour or undergo instrumental delivery. In these women, having an episiotomy was associated with postpartum haemorrhage (adjusted odds ratio, aOR: 1.26; 95% confidence interval, CI: 1.08-1.46) and postnatal hospitalization for more than 4 days (aOR: 1.14; 95% CI: 1.00-1.29). Among multiparous women only, episiotomy was positively associated with a third- or fourth-degree perineal tear (aOR: 2.00; 95% CI: 1.31-3.06); in contrast, among primiparous women the association was negative (aOR: 0.47; 95% CI: 0.37-0.60). Episiotomy was performed in far fewer Vietnamese-born women giving birth in Australia than in Viet Nam, where more than 85% undergo the procedure, and was not associated with adverse outcomes. A lower episiotomy rate should be achievable in Viet Nam.

    Despite a high prevalence of liver disease in Viet Nam, there has been no nationwide approach to the disease and no systematic screening of at-risk individuals. Risk factors include chronic hepatitis B (estimated prevalence of 12%), chronic hepatitis C (at least 2% prevalence), and heavy consumption of alcohol among men. This combination of factors has resulted in liver cancer being the most common cause of cancer death in Viet Nam. There is a general lack of understanding by both the general public and health-care providers about the major risk to health that liver disease represents. We report here the initial steps taken as part of a comprehensive approach to liver disease that will ultimately include nationwide education for health-care providers, health educators, and the public; expansion of nationwide screening for hepatitis B and C followed by hepatitis B virus vaccination or treatment of chronic hepatitis B and/or hepatitis C; education about alcoholic liver disease; long-term surveillance for liver cancer; reduction of infection transmission related to medical, commercial, and personal re-use of contaminated needles, syringes, sharp instruments, razors, and inadequately sterilized medical equipment; and ongoing collection and analysis of data about the prevalence of all forms of liver disease and the results of the expanded screening, vaccination, and treatment programs. We report the beginning results of our pilot hepatitis B screening program. We believe that this comprehensive nationwide approach could substantially reduce the morbidity and mortality from liver disease and greatly lessen the burden in terms of both lives lost and health-care costs. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    Hanoi is the capital of Viet Nam and the second largest city in this country (population: 6.45 million in 2009). Hanoi city has developed along the Red River and has many lakes, ponds and canals. However, recent rapid urbanization of this city has reduced number of natural water areas such as ponds and lakes by reclamation not only in the central area but the suburban area. Canals also have been reclaimed or cut into pieces. Contrary, number of artificial water areas such as fish cultivation pond has rapidly increased. On the other hand, various kind of waste water flows into these natural and artificial water areas and induces pollution and eutrophication. These waste waters also have possibility of pollution of groundwater that is one of major water resources in this city. In addition, groundwater in this area has high concentrations of Arsenic, Fe and NH4. Thus, groundwater use may causes re-circulation of Arsenic. However, studies on the interaction between surface water areas and groundwater and on the role of surface water areas for solute transport with water cycle are a few. Therefore, we focused on these points and took water samples of river, pond and groundwater from four communities in suburban areas: two communities are located near the Red River and other two are far from the River. Also, columnar sediment samples of these ponds were taken and pore water was abstracted. Major dissolved ions, metals and stable isotopes of oxygen and hydrogen of water samples were analyzed. As for water cycle, from the correlation between δ18O and δD, the Red River water (after GNIR) were distributed along the LMWL (δD=8.2δ18O+14.1, calculated from precipitation (after GNIP)). On the other hand, although the pond waters in rainy season were distributed along the LMWL, that in dry season were distributed along the local evaporation line (LEL, slope=5.6). The LEL crossed with the LMWL at around the point of weighted mean values of precipitation in rainy season and of

    Hanoi city, the capital of Viet Nam, has developed beside the Red river. Recent rapid urbanization of this city has reduced a large number of natural water areas such as lakes, ponds and canals not only in the central area but the suburban area. Contrary, the urbanization has increased artificial water areas such as pond for fish cultivation and landscaping. On the other hand, the urbanization has induced the inflow of waste water from households and various kinds of factories to these water areas because of delay of sewerage system development. Inflow of the waste water has induced eutrophication and pollution of these water areas. Also, there is a possibility of groundwater pollution by infiltration of polluted surface water. However, the role of these water areas for water cycle and solute transport is not clarified. Therefore, this study focuses on the interaction between surface water areas and groundwater in Hanoi city to evaluate appropriate land development and groundwater resource management. We are carrying out three approaches: a) understanding of geochemical characteristics of surface water and groundwater, b) monitoring of water levels of pond and groundwater, c) sampling of soil and pond sediment. Correlation between d18O and dD of precipitation (after GNIP), the Red River (after GNIR) and the water samples of this study showed that the groundwater is composed of precipitation, the Red River and surface water that has evaporation process. Contribution of the surface water with evaporation process was widely found in the study area. As for groundwater monitoring, the Holocene aquifers at two sites were in unconfined condition in dry season and the groundwater levels in the aquifer continued to increase through rainy season. The results of isotopic analysis and groundwater level monitoring showed that the surface water areas are one of the major groundwater sources. On the other hand, concentrations of dissolved Arsenic (filtered by 0.45um) in the pore

    Background Anemia affects over 500 million women, and in pregnancy is associated with impaired maternal and infant outcomes. Intermittent antenatal iron supplementation is an attractive alternative to daily dosing; however, the impact of this strategy on infant outcomes remains unclear. We compared the effect of intermittent antenatal iron supplementation with daily iron supplementation on maternal and infant outcomes in rural Viet Nam. Methods and Findings This cluster randomised trial was conducted in Ha Nam province, Viet Nam. 1,258 pregnant women (<16 wk gestation) in 104 communes were assigned to daily iron–folic acid (IFA), twice weekly IFA, or twice weekly multiple micronutrient (MMN) supplementation. Primary outcome was birth weight. Mean birth weight was 3,148 g (standard deviation 416). There was no difference in the birth weights of infants of women receiving twice weekly IFA compared to daily IFA (mean difference [MD] 28 g; 95% CI −22 to 78), or twice weekly MMN compared to daily IFA (MD −36.8 g; 95% CI −82 to 8.2). At 32 wk gestation, maternal ferritin was lower in women receiving twice weekly IFA compared to daily IFA (geometric mean ratio 0.73; 95% CI 0.67 to 0.80), and in women receiving twice weekly MMN compared to daily IFA (geometric mean ratio 0.62; 95% CI 0.57 to 0.68), but there was no difference in hemoglobin levels. Infants of mothers who received twice weekly IFA had higher cognitive scores at 6 mo of age compared to those who received daily IFA (MD 1.89; 95% CI 0.23 to 3.56). Conclusions Twice weekly antenatal IFA or MMN did not produce a clinically important difference in birth weight, when compared to daily IFA supplementation. The significant improvement in infant cognitive outcomes at 6 mo of age following twice weekly antenatal IFA requires further exploration, and provides additional support for the use of intermittent, rather than daily, antenatal IFA in populations with low rates of iron deficiency.

    2013-01-01

    Background Men who have sex with men in Viet Nam have been under-studied as a high-risk group for HIV infection, and this population’s percentage and determinants of HIV testing have not been comprehensively investigated. Methods A national Internet-based survey of self-reported sexual and health seeking behaviours was conducted between August and October 2011 with 2077 Vietnamese men who had sex with men in the last twelve months to identify the frequency of ‘never testing for HIV’ among Internet-using MSM living in Viet Nam, as well as the factors associated with this HIV-related high-rish behavior. Logistic regression analyses were conducted to assess the demographic characteristics and behaviours predicting never testing for HIV. Results A total of 76.5% of men who have sex with men who were surveyed reported never having been voluntarily tested for HIV. Predictors of never being tested included having a monthly income less than VND 5 Million, being a student, using the Internet less than 15 hour per week, and not participating in a behavioural HIV intervention. Conclusions Never testing for HIV is common among Internet-using men who have sex with men in Viet Nam. Given the dangerously high prevalence of this high-risk behaviour, our findings underscore the urgent need for segmented and targeted HIV prevention, care and treatment strategies, focusing on drastically reducing the number of men who have sex with men never testing for HIV in Viet Nam.

    Bats and rodents are being increasingly recognized as reservoirs of emerging zoonotic viruses. Various studies have investigated bat viruses in tropical regions, but to date there are no data regarding viruses with zoonotic potential that circulate in bat and rat populations in Viet Nam. To address this paucity of data, we sampled three bat farms and three wet markets trading in rat meat in the Mekong Delta region of southern Viet Nam. Faecal and urine samples were screened for the presence of RNA from paramyxoviruses, coronaviruses and filoviruses. Paramyxovirus RNA was detected in 4 of 248 (1%) and 11 of 222 (4.9%) bat faecal and urine samples, respectively. Coronavirus RNA was detected in 55 of 248 (22%) of bat faecal samples; filovirus RNA was not detected in any of the bat samples. Further, coronavirus RNA was detected in 12 of 270 (4.4%) of rat faecal samples; all samples tested negative for paramyxovirus. Phylogenetic analysis revealed that the bat paramyxoviruses and bat and rat coronaviruses were related to viruses circulating in bat and rodent populations globally, but showed no cross-species mixing of viruses between bat and rat populations within Viet Nam. Our study shows that potentially novel variants of paramyxoviruses and coronaviruses commonly circulate in bat and rat populations in Viet Nam. Further characterization of the viruses and additional human and animal surveillance is required to evaluate the likelihood of viral spillover and to assess whether these viruses pose a risk to human health. © 2017 The Authors.

    Highly pathogenic avian influenza A(H5N1) is endemic in poultry in Viet Nam. The country has experienced the third highest number of human infections with influenza A(H5N1) in the world. A study in Hanoi in 2001, before the epizootic that was identified in 2003, found influenza A(H5N1) specific antibodies in 4% of poultry market workers (PMWs). We conducted a seroprevalence survey to determine the seroprevalence of antibodies to influenza A(H5N1) among PMWs in Hanoi, Thaibinh and Thanhhoa provinces. We selected PMWs from five markets, interviewed them and collected blood samples. These were then tested using a horse haemagglutination inhibition assay and a microneutralization assay with all three clades of influenza A(H5N1) viruses that have circulated in Viet Nam since 2004. The overall seroprevalence was 6.1% (95% confidence interval: 4.6-8.3). The highest proportion (7.2%) was found in PMWs in Hanoi, and the majority of seropositive subjects (70.3%) were slaughterers or sellers of poultry. The continued circulation and evolution of influenza A(H5N1) requires comprehensive surveillance of both human and animal sites throughout the country with follow-up studies on PMWs to estimate the risk of avian-human transmission of influenza A(H5N1) in Viet Nam.

    Men who have sex with men (MSM) are one of the largest HIV risk groups in Viet Nam and have been understudied. Sexual concurrency and multiple sex partnerships may contribute to high HIV incidence among MSM in Viet Nam. Limited information is available on concurrency and multiple sexual partnerships among MSM in Viet Nam or on the extent to which this population engages in concurrent and multiple unprotected anal intercourse. Data are from a self-administered Internet-based survey of Vietnamese MSM aged 18 years or older, having sex with male partner(s) in the last 12 months and recruited from social networking MSM-specific websites in Viet Nam. Multiple partnerships and concurrency were measured using the UNAIDS-recommended sexual partner matrix, a key component in the questionnaire. Concurrent and multiple sexual partnerships were analyzed at the individual level. Logistic regression analyses were conducted to assess the demographic characteristics and behaviors associated with multiple sexual partnerships. A total of 1695 MSM reported on multiple sexual partnerships; 69.5% indicated multiple sexual partnerships in the last 6 months. A total of 257 MSM reported on concurrent sexual partnerships, with 51.0% reporting penetrative sex with concurrent partners in the last 6 months. Respondents were more likely to engage in multiple sexual partnerships if they were no longer a student, consumed alcohol before and/or during sex, used the Internet to meet casual sex partners and had never participated in a behavioral HIV intervention. Multiple sexual partnerships in the previous 6 months were common among MSM surveyed, as was sexual concurrency. High levels of multiple and concurrent sexual partnerships may be catalyzing the transmission of HIV among MSM in Viet Nam. Given the high prevalence of this high-risk sexual behavior, our findings underscore the urgent need for targeted prevention efforts, focusing on the reduction of multiple and concurrent sexual partners

    Lower Devonian corals and stromatoporoids have recently been discovered in limestones among low grade metamorphic rocks on the western margin of the Kon Tum Block (South Viet Nam). This unit has been identified as the Cu Brei Formation. Coral and stromatoporoid species have been described including Squameofavosites aff. spongiosus, Parallelostroma cf. multicolumnum, Amphipora cf. rasilis, A. cf. raritalis, Simplexodictyon cf. artyschtense, Stromatopora cf. boriarchinovi and Stromatopora sp. indet. The Cu Brei Formation is exposed in a small area 6 km in length and 3 km wide at the foot of Cu Brei Mountain (Sa Thay District, Kon Tum Province). As this formation is in marine shelf facies it is probable that further exposures of Lower Devonian sediments may be discovered in the Kon Tum Block. This discovery raises the question of the tectonic history of the metamorphic Kon Tum Block. It is possible that the block was not an area of positive uplift from the beginning of Paleozoic as has been supposed, but was submerged in a marine environment, at least on its outer margins, in the Devonian, and possibly even earlier, in Early Paleozoic.

    Researchers who use remotely sensed data can spend half of their total effort analysing prior data. If this data preprocessing does not match the application, this time spent on data analysis can increase considerably and can lead to inaccuracies. Despite the existence of a number of methods for pre-processing Landsat time series, each method has shortcomings, particularly for mapping forest changes under varying illumination, data availability and atmospheric conditions. Based on the requirements of mapping forest changes as defined by the United Nations (UN) Reducing Emissions from Forest Degradation and Deforestation (REDD) program, the accurate reporting of the spatio-temporal properties of these changes is necessary. We compared the impact of three fundamentally different radiometric preprocessing techniques Moderate Resolution Atmospheric TRANsmission (MODTRAN), Second Simulation of a Satellite Signal in the Solar Spectrum (6S) and simple Dark Object Subtraction (DOS) on mapping forest changes using Landsat time series data. A modification of Breaks For Additive Season and Trend (BFAST) monitor was used to jointly map the spatial and temporal agreement of forest changes at test sites in Ethiopia and Viet Nam. The suitability of the pre-processing methods for the occurring forest change drivers was assessed using recently captured Ground Truth and high resolution data (1000 points). A method for creating robust generic forest maps used for the sampling design is presented. An assessment of error sources has been performed identifying haze as a major source for time series analysis commission error.

    In the last several years, the interest in forest biomass and carbon stock estimation has increased due to its importance for forest management, modelling carbon cycle, and other ecosystem services. However, no estimates of biomass and carbon stocks of deferent forest cover types exist throughout in the Xuan Lien Nature Reserve, Thanh Hoa, Viet Nam. This study investigates the relationship between above ground carbon stock and different vegetation indices and to identify the most likely vegetation index that best correlate with forest carbon stock. The terrestrial inventory data come from 380 sample plots that were randomly sampled. Individual tree parameters such as DBH and tree height were collected to calculate the above ground volume, biomass and carbon for different forest types. The SPOT6 2013 satellite data was used in the study to obtain five vegetation indices NDVI, RDVI, MSR, RVI, and EVI. The relationships between the forest carbon stock and vegetation indices were investigated using a multiple linear regression analysis. R-square, RMSE values and cross-validation were used to measure the strength and validate the performance of the models. The methodology presented here demonstrates the possibility of estimating forest volume, biomass and carbon stock. It can also be further improved by addressing more spectral bands data and/or elevation.

    Blooms of haptophyte algae in the south central coastal waters of Viet Nam often occur in association with upwelling phenomenon during the southwest (SW) monsoon. Depending on the magnitude of the blooms, damage to aquaculture farms may occur. Based on two years of data on biology, oceanography, and marine chemistry, the present study suggests a conceptual model of the growth of the haptophyte Phaeocystis globosa. At the beginning of the bloom, low temperature and abundant nutrient supply, especially nitrate from rain and upwelling, favour bloom development. Diatoms utilize available nitrate and phosphate; subsequently, higher ammonium concentration allows P. globosa to grow faster than the diatoms. At the end of the Phaeocystis bloom, free cells may become available as food for a heterotrophic dinoflagellate species, Noctiluca scintillans. During and after the phytoplankton bloom, remineralization by bacteria reduces dissolved oxygen to a very low concentration at depth, and favors growth of nitrate-reducing bacteria.A Lagrangian Harmful Algal Bloom (HAB) model, driven by a circulation model of the area, realistically simulates the transport of microalgae in surface waters during strong and weak SW monsoon periods, suggesting that it may be a good tool for early warning of HABs in Vietnamese coastal waters.

    We examined the potential for HIV and hepatitis C (HCV) transmission across persons who inject drugs (PWID), men-who-have-sex-with-men (MSM) and female commercial sex workers (CSW) PWID and the potential for sexual transmission of HIV from PWID to the general population in Hai Phong, Viet Nam. Using respondent driven and convenience sampling we recruited 603 participants in 2014. All participants used heroin; 24% used non-injected methamphetamine. HIV prevalence was 25%; HCV prevalence was 67%. HIV infection was associated with HCV prevalence and both infections were associated with length of injecting career. Reported injecting risk behaviors were low; unsafe sexual behavior was high among MSM-PWID and CSW-PWID. There is strong possibility of sexual transmission to primary partners facilitated by methamphetamine use. We would suggest future HIV prevention programs utilize multiple interventions including "treatment as prevention" to potential sexual transmission of HIV among MSM and CSW-PWID and from PWID to the general population.

    Groundwater plays an importance role for domestic, industrial, and agricultural uses in Ho Chi Minh city, Viet Nam. This study is objected to evaluate the sustainability of groundwater by using groundwater sustainability indicators (GWSIs) defined by UNESCO/IAEA/IAH Working Group on Groundwater Indicators at aquifer scale (the Upper Pliocene aquifer). There are four main indicators selected and one new indicator designed for the particular characteristic of Ho Chi Minh city which is under influence of by saline-water intrusion. The results indicated groundwater of the Upper Pliocene aquifer, the main groundwater supply source, is generally in the unsustainable state. The abstraction of groundwater, which was much greater than its capability, is probably causing the serious state of annual groundwater depletion and saline-water intrusion. The GWSIs, which expressed in such a simple way but scientifically-based and policy-relevant, proved its usefulness in evaluating the sustainability of groundwater at the aquifer scale in Ho Chi Minh city, and subsequently should be incorporated in water resource management practices.

    Despite recommendations supporting optimal breastfeeding, the number of women practicing exclusive breastfeeding (EBF) remains low, and few interventions have demonstrated implementation and impact at scale. Alive & Thrive was implemented over a period of 6 y (2009-2014) and aimed to improve breastfeeding practices through intensified interpersonal counseling (IPC), mass media (MM), and community mobilization (CM) intervention components delivered at scale in the context of policy advocacy (PA) in Bangladesh and Viet Nam. In Bangladesh, IPC was delivered through a large non-governmental health program; in Viet Nam, it was integrated into government health facilities. This study evaluated the population-level impact of intensified IPC, MM, CM, and PA (intensive) compared to standard nutrition counseling and less intensive MM, CM, and PA (non-intensive) on breastfeeding practices in these two countries. A cluster-randomized evaluation design was employed in each country. For the evaluation sample, 20 sub-districts in Bangladesh and 40 communes in Viet Nam were randomized to either the intensive or the non-intensive group. Cross-sectional surveys (n ~ 500 children 0-5.9 mo old per group per country) were implemented at baseline (June 7-August 29, 2010, in Viet Nam; April 28-June 26, 2010, in Bangladesh) and endline (June 16-August 30, 2014, in Viet Nam; April 20-June 23, 2014, in Bangladesh). Difference-in-differences estimates (DDEs) of impact were calculated, adjusting for clustering. In Bangladesh, improvements were significantly greater in the intensive compared to the non-intensive group for the proportion of women who reported practicing EBF in the previous 24 h (DDE 36.2 percentage points [pp], 95% CI 21.0-51.5, p Viet Nam, EBF increases were greater in the intensive group (27.9 pp, 95% CI 17.7-38.1, p Viet Nam than standard counseling with less intensive MM, CM, and PA.

    A cross-sectional survey was conducted in three districts of Quang Ninh province, Viet Nam, to find out what proportion of the people who lived there engaged in behaviour that put them at risk of becoming infected with HIV, and to measure their knowledge about HIV infection and AIDS. The survey was conducted in a rural district, Yen Hung; a mountainous district inhabited primarily by ethnic minority groups, Binh Lieu; and an urban district, Ha Long. Participants aged 15-45 years were randomly selected from the general population to be interviewed. A total of 630 people from 707 households were interviewed; 8% were not home despite repeated visits and 3% refused to participate. The prevalence of premarital intercourse ranged from 9% to 16% among married men and 4% to 7% among married women. Among single men the proportion who had ever had intercourse ranged from 6% to 16%. Fewer than 3% reported having ever had sex with a sex worker. The median number of extramarital sex partners was 1. Knowledge about HIV/AIDS was high in the urban and rural areas but low in the mountainous area. Being male and being 20-29 years old were associated with having multiple sex partners. The low prevalence of individuals reporting that they had had intercourse with sex workers and partners other than their spouse may explain the low rates of HIV infection among the heterosexual population; these rates are in contrast to the high rates of HIV infection found among injecting drug users. The association between having extramarital partners and being a younger man suggests that the tendency to have more sexual partners may increase in the future. If this happens, the potential for HIV to be spread through heterosexual sex will increase.

    Dengue is a clinically important arthropod-borne viral disease with increasing global incidence. Here we aimed to estimate the prevalence of dengue infections in Khanh Hoa Province, central Viet Nam, and to identify risk factors for infection. We performed a stratified cluster sampling survey including residents of 3-60 years of age in Nha Trang City, Ninh Hoa District and Dien Khanh District, Khanh Hoa Province, in October 2011. Immunoglobulin G (IgG) and immunoglobulin M (IgM) against dengue were analyzed using a rapid test kit. Participants completed a questionnaire exploring clinical dengue incidence, socio-economic status, and individual behavior. A household checklist was used to examine environment, mosquito larvae presence, and exposure to public health interventions. IgG positivity was 20.5% (urban, 16.3%; rural, 23.0%), IgM positivity was 6.7% (urban, 6.4%; rural, 6.9%), and incidence of clinically compatible dengue during the prior 3 months was 2.8 per 1,000 persons (urban, 1.7; rural, 3.4). For IgG positivity, the adjusted odds ratio (AOR) was 2.68 (95% confidence interval [CI], 1.24-5.81) for mosquito larvae presence in water pooled in old tires and was 3.09 (95% CI, 1.75-5.46) for proximity to a densely inhabited area. For IgM positivity, the AOR was 3.06 (95% CI, 1.50-6.23) for proximity to a densely inhabited area. Our results indicated rural penetration of dengue infections. Control measures should target densely inhabited areas, and may include clean-up of discarded tires and water-collecting waste.

  12. Evidence for the Convergence Model: The Emergence of Highly Pathogenic Avian Influenza (H5N1 in Viet Nam.

    Directory of Open Access Journals (Sweden)

    Sumeet Saksena

    Full Text Available Building on a series of ground breaking reviews that first defined and drew attention to emerging infectious diseases (EID, the 'convergence model' was proposed to explain the multifactorial causality of disease emergence. The model broadly hypothesizes disease emergence is driven by the co-incidence of genetic, physical environmental, ecological, and social factors. We developed and tested a model of the emergence of highly pathogenic avian influenza (HPAI H5N1 based on suspected convergence factors that are mainly associated with land-use change. Building on previous geospatial statistical studies that identified natural and human risk factors associated with urbanization, we added new factors to test whether causal mechanisms and pathogenic landscapes could be more specifically identified. Our findings suggest that urbanization spatially combines risk factors to produce particular types of peri-urban landscapes with significantly higher HPAI H5N1 emergence risk. The work highlights that peri-urban areas of Viet Nam have higher levels of chicken densities, duck and geese flock size diversities, and fraction of land under rice or aquaculture than rural and urban areas. We also found that land-use diversity, a surrogate measure for potential mixing of host populations and other factors that likely influence viral transmission, significantly improves the model's predictability. Similarly, landscapes where intensive and extensive forms of poultry production overlap were found at greater risk. These results support the convergence hypothesis in general and demonstrate the potential to improve EID prevention and control by combing geospatial monitoring of these factors along with pathogen surveillance programs.

    Second-hand tobacco smoke (SHS) exposure at home, especially among children, is a serious issue in Viet Nam. During the past decade, much effort has been taken for tobacco control in the country, including various prgorammes aiming to reduce SHS exposure among adults and children. This article analysed trends and factors associated with SHS exposure at home among school children aged 13-15 in Viet Nam, using the Global Youth Tobacco Surveys conducted in 2007 and 2014. Descriptive and inferential statistical methods with logistic regression were applied. Overall, there was a significant reduction in the level of exposure, from 58.5% (95%CI: 57.6-59.3) in 2007 to 47.1% (95%CI: 45.4-48.8) in 2014. Of the associated factors, having one or both parents smoking was significantly associated with the highest odds of SHS exposure at home (OR=5.0; 95%CI: 4.2-6.1). Conversely, having a mother with a college or higher education level was found to be a protective factor (OR=0.5; 95%CI: 0.3-0.8).

    Survey data from men who have sex with men (MSM) in Asian cities indicate drastic increases in HIV prevalence. It is unknown which factors are most important in driving these epidemics. The objective of this study was to identify patterns of condom use among MSM Internet users living in Viet Nam, as well as risk factors associated with inconsistent condom use and non-condom use. A national Internet-based survey of sexual behaviours was administered in 2011. Results showed that 44.9% of MSM reported not using a condom during their last anal sex encounter with a male partner. MSM were less likely to report condom use during anal sex with long-term partners than with casual partners. Twenty-three and a half per cent of MSM surveyed had ever taken an HIV test and received the results. Study findings highlight the urgent need for targeted strategies focused on increasing the rate of consistent condom use during anal sex with male partners among MSM in Viet Nam.

    The widespread availability of computer hardware and software for recording and storing disease event information means that, in theory, we have the necessary information to carry out detailed analyses of factors influencing the spatial distribution of disease in animal populations. However, the reliability of such analyses depends on data quality, with anomalous records having the potential to introduce significant bias and lead to inappropriate decision making. In this paper we promote the use of exceedance probabilities as a tool for detecting anomalies when applying hierarchical spatio-temporal models to animal health data. We illustrate this methodology through a case study data on outbreaks of foot-and-mouth disease (FMD) in Viet Nam for the period 2006-2008. A flexible binomial logistic regression was employed to model the number of FMD infected communes within each province of the country. Standard analyses of the residuals from this model failed to identify problems, but exceedance probabilities identified provinces in which the number of reported FMD outbreaks was unexpectedly low. This finding is interesting given that these provinces are on major cattle movement pathways through Viet Nam. Copyright © 2014 Elsevier Ltd. All rights reserved.

  16. The context of HIV risk behaviours among HIV-positive injection drug users in Viet Nam: Moving toward effective harm reduction

    Full Text Available Abstract Background Injection drug users represent the largest proportion of all HIV reported cases in Viet Nam. This study aimed to explore the perceptions of risk and risk behaviours among HIV-positive injection drug users, and their experiences related to safe injection and safe sex practices. Methods This study used multiple qualitative methods in data collection including in-depth interviews, focus group discussions and participant observation with HIV-positive injection drug users. Results The informants described a change in the sharing practices among injection drug users towards more precautions and what was considered 'low risk sharing', like sharing among seroconcordant partners and borrowing rather than lending. However risky practices like re-use of injection equipment and 'syringe pulling' i.e. the use of left-over drugs in particular, were frequently described and observed. Needle and syringe distribution programmes were in place but carrying needles and syringes and particularly drugs could result in being arrested and fined. Fear of rejection and of loss of intimacy made disclosure difficult and was perceived as a major obstacle for condom use among recently diagnosed HIV infected individuals. Conclusion HIV-positive injection drug users continue to practice HIV risk behaviours. The anti-drug law and the police crack-down policy appeared as critical factors hampering ongoing prevention efforts with needle and syringe distribution programmes in Viet Nam. Drastic policy measures are needed to reduce the very high HIV prevalence among injection drug users.

    Quantifying the dynamics of the early stages in the life cycle of mangroves is essential to predict the distribution, species composition and structure of mangrove forests, and their maintenance and recovery from perturbations. The growth and population dynamics of two stands of the mangrove Kandelia candel in Halong Bay (Viet Nam) were examined for 1 year. Growth was highly seasonal, with high growth rates and fast internode formation in the summer, dropping to extremely low growth during January-February, the coldest and driest months in the year. In addition, growth and internode formation rates showed important inter-annual variability during the last decade. The complete reproductive period required 7-8 months. Flower initiation was maximal in June and peak propagule maturity occurred in December-January. Only one mature propagule developed for every 67 and 127 inflorescence buds formed at Site 1 and Site 2, respectively. Kandelia candel propagules begun to sink 10 days after being released, and after 18 days all propagules had negative buoyancy. The propagules developed roots within 19-68 days, depending on whether they were held on the water or sediment, and were capable of long range dispersal, for 15-20% of them dispersed more than 100 m within 1 day. The median age of K. candel plants ranged between 8.7 and 5.6 years, with a density of 1900 and 470 plants ha -1, in Sites 1 and 2. Plant mortality was high, with 64 and 74% of the plants surviving after a year at Sites 1 and 2. Life expectancy (i.e. median age-at-death) of only 2.2 and 2.7 years at Sites 1 and 2, respectively, indicates that mortality of young K. candel plants was specially high. Recruitment occurred in early spring, and did not suffice to balance the mortality within the annual period examined. These results suggest that the K. candel stands in Halong Bay might be maintained by a few years of high recruitment which would compensate for generally high mortality rates.

    A prospective cohort study of avian influenza infection in poultry flocks was carried out in the Mekong River Delta of Viet Nam between December 2008 and April 2010. Our objectives were to (i) estimate the prevalence and incidence of avian influenza virus infection and (ii) assess the efficacy of H5N1 vaccination programmes as indicated by the presence of H5 antibody in vaccinated and unvaccinated poultry. Real-time PCR and H5 multiplex assays were used to detect the antigen of avian influenza viruses from swab samples. The haemagglutination inhibition test was used to detect H5 antibody. A total of 17 968 swab and 14 878 blood samples were collected from 5476 birds over the study period. The overall incidence rate of influenza type A virus infection was 5 (95% CI 4-7) positive birds per 100 bird-months at risk. The overall incidence rate of H5 virus infection was 0.2 (95% CI 0.1-0.5) positive birds per 100 bird-months at risk. Fifty (95% CI 48-52) birds per 100 tested birds were H5 HI positive in the unvaccinated group compared with 71 (95% CI 69-73) birds per 100 in the vaccinated group. Influenza type A and H5 viruses were circulating in village poultry throughout the study period with no recorded signs of clinical disease. This implies that interventions need to be carried out continuously throughout the year rather than only focusing on the established high-risk periods. Broiler ducks had an incidence rate of influenza H5 virus infection approximately four times greater than that of layer ducks and in-contact species. We conclude that broiler ducks are likely to be the main entry route for H5 virus into poultry flocks in the MRD. Control efforts would benefit from understanding why there is a difference between villages in H5 incidence and developing strategies to provide greater protection to broiler ducks. © 2013 Blackwell Verlag GmbH.

    We conducted a cross-sectional study to examine the perceptions of quality of life among people living with HIV who received home-based care services administered through outpatient clinics in Ho Chi Minh City, Viet Nam. Data were collected from a sample of 180 consecutively selected participants (86 cases, 94 controls) at four outpatient clinics, all of whom were on antiretroviral therapy. Quality of life was evaluated using the WHOQOL-BREF instrument. In adjusted analysis, those who received home-based care services had a quality of life score 4.08 points higher (on a scale of 100) than those who did not receive home-based care services (CI 95%, 2.32-5.85; p < 0.001). The findings suggest that home-based care is associated with higher self-perceptions of quality of life among people living with HIV.

    Extensively drug-resistant tuberculosis (XDR-TB) represents an emerging public health problem worldwide. According to the World Health Organization, an estimated 9.7% of multidrug-resistant TB (MDR-TB) cases are defined as XDR-TB globally. The objective of this study was to determine the prevalence of drug resistance to second-line TB drugs among MDR-TB cases detected in the Fourth National Anti-Tuberculosis Drug Resistance Survey in Viet Nam. Eighty clusters of TB cases were selected using a probability-proportion-to-size approach. To identify MDR-TB cases, drug susceptibility testing (DST) was performed for the four major first-line TB drugs. DST of second-line drugs (ofloxacin, amikacin, kanamycin, capreomycin) was performed on isolates from MDR-TB cases to identify pre-XDR and XDR cases. A total of 1629 smear-positive TB cases were eligible for culture and DST. Of those, DST results for first-line drugs were available for 1312 cases, and 91 (6.9%) had MDR-TB. Second-line DST results were available for 84 of these cases. Of those, 15 cases (17.9%) had ofloxacin resistance and 6.0% were resistant to kanamycin and capreomycin. Five MDR-TB cases (6.0%) met the criteria of XDR-TB. This survey provides the first estimates of the proportion of XDR-TB among MDR-TB cases in Viet Nam and provides important information for local policies regarding second-line DST. Local policies and programmes that are geared towards TB prevention, early diagnosis and treatment with effective regimens are of high importance.

    The aim of this paper is to report the rate of current and ever cigarette smoking and explore correlates of current cigarette smoking among adolescents aged 13-15 in Viet Nam. This analysis was derived from GYTS survey, which comprised of 3,430 adolescents aged 13-15, conducted in 2014 in 13 cities and provinces of Viet Nam. We calculated the weighted rates of current and ever cigarette smoking and reported patterns of smoking behavior. We also performed logistic regression to explore correlates of current cigarette smoking behavior. The weighted rate of ever cigarette smoking was 9.5% (95% confidence interval (CI): 8.5 %-10.5%), in which the weighted rate among males (15.4%; 95% CI: 13.6%-17.0%) was higher than that among females (4.2%; 95% CI: 3.3%-5.1%). The weighted rate of current cigarette smoking was relatively low at 2.5% (95%CI: 2.0%- 3.0%) with higher weighted rate among males (4.9%; 95% CI: 3.8%-5.9%) compared to the corresponding figure among females (0.2%; 95% CI: 0.0 %-0.5%). Current cigarette smoking was significantly higher among males than females, in students aged 15 versus 13 years old, and in students who had several or all close friends smoking and students with daily observation of smoking at school. For greater smoking reduction outcomes, we recommend that tobacco interventions for adolescents should consider targeting more male students at older ages, establish stricter adherence to school-based banning of cigarette smoking, engage both smoking and nonsmoking adolescents and empower adolescents to resist peer smoking influence as well as changing their norms or beliefs towards smoking benefits.

    The document contains two parts. The first part stipulates the agreement of Viet Nam to accept safeguards on all source or special fissionable material in all peaceful nuclear activities within its territory, under its jurisdiction or carried out under its control anywhere, for the exclusive purpose of verifying that such material is not diverted to nuclear weapons or other nuclear explosive devices. The second part specifies the procedures to be applied in the implementation of the safeguards provisions of Part I

  11. The harmony of family and the silence of women: sexual attitudes and practices among rural married women in northern Viet Nam.

    Women in Viet Nam have long had to face various sexual and reproductive health problems, ranging from abortion to reproductive tract infections (RTIs) and sexual coercion. These issues have increasingly been addressed by scholars in the fields of public health and social sciences through sexual and reproductive health research and in other ways. Despite this, there remains a lack of in-depth information on attitudes and practices regarding sex and sexuality of Vietnamese women today. This paper in part responds to the knowledge gap by reporting on findings from qualitative research on sexual attitudes and practices among rural married women in a Northern rural community, measured against the broader social and cultural context. Twenty-five women in total were interviewed; and two focus group discussions were conducted. The findings show that women generally believe that men are (or should be) the initiators in sexual relations. Many women feel reluctant to refuse sex to their husbands or communicate openly about sex and sexuality. However, this paper also demonstrates that women are not totally passive in sexual relations. Women in this study used a range of strategies to negotiate their sexual life, and sometimes 'silence' is used as a form of agency in order to maintain harmony and happiness within the family.

    Setting: Ho Chi Minh City (HCMC), Viet Nam. Objective: To evaluate a new integrated service model for human immunodeficiency virus/acquired immune-deficiency syndrome (HIV/AIDS) care. Design: In HCMC, co-located services, including voluntary HIV counseling and testing (VCT), HIV treatment at out-patient clinics (OPC), and methadone maintenance therapy (MMT) for persons who inject drugs, have operated under different administrative structures. In the context of decreasing international financial support, integration of these services into one administrative structure with reduced staff occurred in seven districts in HCMC between October 2013 and June 2014. We used a pre-post study design to compare service-related outcomes from routinely collected data at health facilities 6 months before and 6 months after integration. Results: The proportion of HIV-infected persons linked from VCT to OPCs was unchanged or increased following integration. A higher percentage of patients eligible for antiretroviral therapy (ART) were started on ART. The proportion of ART patients lost to follow-up remained unchanged. The proportions of MMT patients who tested positive for heroin or other substances decreased or were unchanged. Conclusions: VCT, OPC and MMT service delivery quality remained the same or improved during the 6 months following the integration. Expansion of the integrated model should be considered for HIV-related services.

    Evaluations were given on the possibility of saving energies and reducing CO2 emission by renewing the shaft kilns operated in four factories in Viet Nam into fluidized bed kilns. The feasibility study is intended to be linked to the clean development mechanism (CDM) in the future. The fluidized bed kiln is a most advanced technology developed to deal with social, economic and technological demands such as global environment preservation, energy conservation, effective utilization of resources, enhancement of economic performance, and diversification of cement needs. The technology is capable of largely reducing greenhouse effect gases, eliminating the problem of dust scattering from sintering facilities, producing stabilized and high-quality clinker, making possible of using inexpensive fuels including low-order coal, using less installation space, and reducing the production cost. The amount of energy reduction in all of the four factories is calculated 8,101 to 9,551 toe/year at an energy saving effect rate of 37 to 44%. CO2 emission is reduced as a result of reduction in fuel for sintering furnaces and in electric power consumption. The reduction amount would be 24,393 to 38,794 tons/year (converted into CO2), and the reduction effect rate would be 36 to 44%. The investment effect looks sufficient as payout of 10 to 12 years if the environment special Yen loan is used. Trial calculation was also performed for the nation-wide proliferation effect. (NEDO)

    The population of Cambodia stood at 6.25 million in 1986, with an average annual growth rate of 2.1%. Life expectancy is presently 42 years for men and 44.9 years for women. The government is currently disputed between resistance groups and Vietnamese-installed authorities in Phnom Penh. No single authority controls the entire country. The urban population increased sharply during the 1970-75 war, but after seizing power the Khmer Rouge forced most urban residents to return to rural areas as peasants. Massive numbers of people were executed for political reasons or died of starvation and disease during the Khmer Rouge period and after the dislocations caused by the Vietnamese invasion: an estimated 1.5-3 million people are estimated to have died out of a 1975 population of 7.3 million. The resistance forces have grown in size and effectiveness since 1985 and now challenge Vietnam's position in Cambodia. The Cambodian economy, badly damaged by the war and the Khmer Rouge regime, has only slowly begun to recover. Per capita gross national product (GNP) is estimated at less than US$100. The food situation remains precarious, with shortages of rice, meat, vegetables, sugar, flour, and dairy products. Extensive damage to the country's irrigation system, on which rice production depends, has only begun to be repaired. Basic services such as electricity and water are erratic. Although literacy and primary education campaigns have achieved success, health conditions remain poor.

    Neogene-Quaternary basalts occur as dispersed volcanic clusters in the vicinity of the Tethyan tectonic belt, possibly representing 'far-field' effects of the Early Tertiary collisions of Gondwana fragments with the southern margin of Eurasia. In Indochina, such a 'Diffuse Igneous Province' post-dates the 45-42 Ma 'hard' India-Asia collision and southeastward, collision induced (c. 30-17 Ma.), extrusion of Indochina. Extrusion was accommodated by left-lateral strike-slip shearing on the Ailao Shan-Red River Fault, coeval with seafloor spreading in the East Viet Nam (South China) Sea. The Indochina basalts mostly comprise shield-building tholeiites capped by small-volume undersaturated types, the latter often bearing mantle xenoliths and 'exotic' xenocrysts such as sapphire, zircon. They appeared at c. 17 Ma, more-or-less coinciding with the cessation of both continental extrusion and seafloor spreading. At this point extensional stress appears to have shifted westwards to continental Indochina, with magmatic activity appearing, characteristically, at 'pull-apart' basins. However, the relationship of mantle melting beneath this region to its geodynamic setting is controversial, being variously attributed to mantle plumes, extreme lithospheric stretching, and lateral asthenospheric displacement. There is little or no definitive evidence for regional mantle upwelling while lithosphere stretching alone appears to be insufficient to allow for melting, Here, we present geochemical and Sr, Nd, and Pb isotopic (and paleomagnetic data), for cored sections from the Pleiku and Buon Mê Thuột plateaus in south-central Viet Nam, representative in most respects of the Indochina province as a whole. In the Pleiku shield olivine tholeiite flows are intercalated with quartz tholeiites while, in contrast, alkali basalts predominate over olivine tholeiite in the Buon Mê Thuột (BMT) shield. The first of these features (in Pleiku) probably reflects crustal wall-rock reaction while

  16. Dengue virus in sub-tropical northern and central Viet Nam: population immunity and climate shape patterns of viral invasion and maintenance.

    Full Text Available Dengue virus transmission occurs in both epidemic and endemic cycles across tropical and sub-tropical regions of the world. Incidence is particularly high in much of Southeast Asia, where hyperendemic transmission plagues both urban and rural populations. However, endemicity has not been established in some areas with climates that may not support year-round viral transmission. An understanding of how dengue viruses (DENV enter these environments and whether the viruses persist in inapparent local transmission cycles is central to understanding how dengue emerges in areas at the margins of endemic transmission. Dengue is highly endemic in tropical southern Vietnam, while increasingly large seasonal epidemics have occurred in northern Viet Nam over the last decade. We have investigated the spread of DENV-1 throughout Vietnam to determine the routes by which the virus enters northern and central regions of the country. Phylogeographic analysis of 1,765 envelope (E gene sequences from Southeast Asia revealed frequent movement of DENV between neighboring human populations and strong local clustering of viral lineages. Long-distance migration of DENV between human population centers also occurred regularly and on short time-scales, indicating human-mediated viral invasion into northern Vietnam. Human populations in southern Vietnam were found to be the primary source of DENV circulating throughout the country, while central and northern Vietnam acted as sink populations, likely due to reduced connectedness to other populations in the case of the central regions and to the influence of temperature variability on DENV replication and vector survival and competence in the north. Finally, phylogeographic analyses suggested that viral movement follows a gravity model and indicates that population immunity and physical and economic connections between populations may play important roles in shaping patterns of DENV transmission.

    Studies have shown that smoking is a learnt behavior, often initiated during adolescence. This paper aims to describe tobacco-related knowledge, attitude and associations among school adolescents aged 13-15 with exposure to anti-smoking information. Using data from the Global Youth Tobacco Survey (GYTS) in Viet Nam, 2014, knowledge was measured through 4 questions about tobacco use, and attitude was assessed through 3 questions on personal, social and environmental aspects. Students giving most anti-tobacco responses to all questions were considered as having correct knowledge or appropriate attitude or both. Access to anti-smoking information was determined by exposure to any media messages on tobacco control during the past 30 days and teaching in school about the danger of tobacco use during the past 12 months. A substantial percentage of students thought that being near others who smoke might be harmful to them and smoking is harmful to health (89.4% and 89.6% respectively). However, only 46.4% reported that it is definitely difficult to quit smoking and 66.9% thought that smoking for only 1 or 2 years, once stopped, is harmful to health. Slightly more than half of the respondents reported appropriate attitude that young smokers have fewer friends than others and smoking makes them less attractive and less comfortable at social events. Noticing anti-smoking messages in the media together with having lessons in school about the dangers of tobacco substantially increased the likelihood of having correct knowledge, appropriate attitude and both. Despite relatively high awareness about smoking harms, effective educational communication is still highly needed to improve the level of comprehensive knowledge and an appropriate attitude regarding tobacco use.

    The relationship between temperature and mortality has been found to be U-, V-, or J-shaped in developed temperate countries; however, in developing tropical/subtropical cities, it remains unclear. Our goal was to investigate the relationship between temperature and mortality in Hue, a subtropical city in Viet Nam. We collected daily mortality data from the Vietnamese A6 mortality reporting system for 6,214 deceased persons between 2009 and 2013. A distributed lag non-linear model was used to examine the temperature effects on all-cause and cause-specific mortality by assuming negative binomial distribution for count data. We developed an objective-oriented model selection with four steps following the Akaike information criterion (AIC) rule (i.e. a smaller AIC value indicates a better model). High temperature-related mortality was more strongly associated with short lags, whereas low temperature-related mortality was more strongly associated with long lags. The low temperatures increased risk in all-category mortality compared to high temperatures. We observed elevated temperature-mortality risk in vulnerable groups: elderly people (high temperature effect, relative risk [RR]=1.42, 95% confidence interval [CI]=1.11-1.83; low temperature effect, RR=2.0, 95% CI=1.13-3.52), females (low temperature effect, RR=2.19, 95% CI=1.14-4.21), people with respiratory disease (high temperature effect, RR=2.45, 95% CI=0.91-6.63), and those with cardiovascular disease (high temperature effect, RR=1.6, 95% CI=1.15-2.22; low temperature effect, RR=1.99, 95% CI=0.92-4.28). In Hue, the temperature significantly increased the risk of mortality, especially in vulnerable groups (i.e. elderly, female, people with respiratory and cardiovascular diseases). These findings may provide a foundation for developing adequate policies to address the effects of temperature on health in Hue City.

    Full Text Available Abstract Background Iron deficiency, anemia and hookworm disease are important public health problems for women of reproductive age living in developing countries and affect the health of newborns and infants. Iron supplementation and deworming treatment are effective in addressing these problems in both pregnant and non-pregnant women. Daily iron supplementation and deworming after the first trimester is recommended for pregnant women although these programs usually do not operate efficiently or effectively. Weekly iron-folic acid supplementation and regular deworming for non-pregnant women may be a viable approach for improving iron status and preventing anemia during the reproductive years. Addressing these diseases at a population level before women become pregnant could significantly improve women's health before and during pregnancy, as well as their infants' growth and development. Methods and Results This paper describes the major processes undertaken in a demonstration intervention of preventive weekly iron-folic acid supplementation with regular deworming for all 52,000 women aged 15–45 years in two districts of Yen Bai province, in northern Viet Nam. The intervention strategy included extensive consultation with community leaders and village, commune, district and provincial health staff, and training for village health workers. Distribution of the drugs was integrated with the existing health service infrastructure and the village health workers were the direct point of contact with women. Iron-folic acid tablets and deworming treatment were provided free of charge from May 2006. An independent Vietnamese NGO was commissioned to evaluate compliance and identify potential problems. The program resulted in effective distribution of iron-folic acid tablets and deworming treatment to all villages in the target districts, with full or partial compliance of 85%. Conclusion Training for health staff, the strong commitment of all partners

    Large areas of mangrove forests were devastated in South Viet Nam during the second Indochina war. After its end in 1975, extensive reforestation with monocultures took place. Can Gio, one of the biggest replanted sites with about 20,000 ha of mangroves mainly Rhizophora apiculata, was declared a biosphere reserve by the UNESCO in 2000. Although this status now enables progressive forest dynamics, there are still drawbacks resulting from the unnatural character of the plantations. For example, the homogeneous size and age structure as well as the regular arrangement of the planted trees make larger forest stands more vulnerable to synchronized collapsing which can be triggered by stronger winds and storms. A transformation into a more natural forest characterized by a heterogeneous age and size structure and a mixed species composition is of urgent need to avoid a synchronized dieback. In this study we test the capability of natural canopy disturbances (e.g. lightning strikes) to facilitate this transformation.Canopy gaps created by lightning strikes were detected and quantified by remote sensing techniques. SPOT satellite images from the years 2003, 2005 and 2007 provided information about the spatial distribution, size, shape, and formation frequency of the gaps. Lightning strike gaps were identified based on their shape and size. They form small openings (mean: 0.025 ha) and their yearly probability of occurrence was determined to be approximately 0.012 per hectare. Selected gaps were surveyed in the field in 2008 to complement the remote sensing data and to provide information upon forest structure and regeneration.Simulation experiments were carried out with the individual-based KiWi mangrove model for quantifying the influence of different lightning regimes on the vertical and horizontal structure of the R. apiculata plantation. In addition, we conducted simulations with a natural and thus randomly generated forest to compare the structure of the two

    In November 1992 a Vietnamese research physicist was working with a microtron accelerator when he received a radiation overexposure that required the subsequent amputation of his right hand. A team from the International Atomic Energy Agency visited Hanoi in March 1993 to carry out an investigation. It was concluded that the accident occurred primarily due to a lack of safety systems although the lack of both written procedures and training in basic radiation safety were also major contributors.

    Scientific evidence on all aspects of smoking amongst youth is very important for designing appropriate interventions to reduce smoking among this vulnerable population. This paper describes current access to antismoking information among school children aged 13 to 15 years in Vietnam in 2014 and examines its potential impact on preventing smoking initiation. The data used in this paper were obtained from the 2014 Global Youth Tobacco Survey (GYTS) in Vietnam. Students were asked questions about their level of awareness of anti-smoking information from various sources in the past 30 days and about lessons in school regarding the dangers of tobacco use during the last 12 months. Those who have never smoked were asked "whether or not they thought about avoiding cigarettes because of health warnings on cigarette packages" and answers were analyzed in combination with data on access to anti-smoking information from other sources. The prevalence of exposure to antismoking campaigns was high among school children in Viet Nam: 55.3% of current smokers reported thoughts of smoking cessation because of health warnings on cigarette packages; 60.5% of never smokers avoided initiating smoking because of the same health warnings. The potential impact of graphic health warnings to prevent school-aged children from smoking initiation would be stronger if there was concurrent access to anti-smoking programs on the dangers of tobacco use in schools. However, school education for tobacco prevention and control has not been as strong as expected. A more comprehensive school curriculum on tobacco prevention and control is recommended to reinforce antismoking messages among school children.

    Purpose Parent-child communication is associated with positive outcomes for youths’ engagement in sexual behaviors. Limited data are available regarding parent-child communication in transitional countries. We present data from Vietnamese parent-youth dyads on parent reproductive health knowledge, comfort of communication, frequency of talk, and discordancy between youths’ reported and parents’ perceptions for engagement in relationships and sexually intimate behaviors. Methods 185 randomly selected parent-youth dyads in four communes in Ha Noi and Khanh Hoa Province. Descriptive and comparative analysis included chi-square tests, independent samples t-tests, and ANOVA. Linear regression analysis was utilized to assess relationships between parental knowledge, level of comfort, frequency of talk, and discordancy. Results Seventy-six percent of parents and 44% of youth were female. Youth mean age was 17.2 years. For parental “reproductive health knowledge” mean score was 24.74 (SD 3.84: range 15–34). Lower parental reproductive health knowledge was positively associated with lower levels of education [F=2.983, df 184: p=0.014]. Data indicate a linear model in which knowledge is related to “comfort” (β =0.17; p=0.048) and “comfort” to frequency of “talk” (β =0.6; psexual touching (β =0.57; p=0.60). Conclusions Parent and youth in Viet Nam are engaged in limited communication about reproductive health. There is need for more data to assess the impact of these communication patterns on youths’ engagement in sexual behaviors and for development of family-centered interventions to increase parental knowledge and skills for positive communication.

    Intermittent iron-folic acid supplementation (IFA) is currently recommended for pregnant women in populations where anaemia prevalence among pregnant women is Viet Nam among children of 36 months of age, born to women previously enrolled in a cluster randomised controlled trial of antenatal micronutrient supplementation (daily IFA (60 mg elemental iron) vs twice-weekly IFA (60 mg elemental iron) vs twice-weekly multiple micronutrient (MMN) supplementation (60 mg elemental iron)). Primary outcomes were height-for-age z-scores (HAZ), according to WHO growth standards and cognitive composite scores (Bayley Scales of Infant and Toddler Development, third edition) at 36 months of age. A total of 1017 children born to mothers enrolled in the cluster randomised trial were assessed at 36 months of age. Adjusted mean differences (MDs) in HAZ were -0.14 (95% CI -0.28 to -0.01) and -0.15 (95% CI -0.29 to -0.01) in children born to mothers who received twice-weekly IFA or MMN compared with those who received daily IFA. Children born to mothers who received twice-weekly MMN had lower composite motor scores compared with those who received daily IFA (MD -2.07, 95% CI -4.11 to -0.03). There were no differences in composite cognitive scores in the twice-weekly compared with daily regimens. Low-dose antenatal IFA supplementation (120 mg elemental iron per week) resulted in lower HAZ and motor composite scores in children compared with higher-dose antenatal IFA supplementation (420 mg elemental iron per week). This highlights the importance of adequate iron stores during pregnancy and the need for careful monitoring when lower-dose antenatal iron regimens are used.

    A better description of the extent and structure of genetic diversity in dengue virus (DENV) in endemic settings is central to its eventual control. To this end we determined the complete coding region sequence of 187 DENV-2 genomes and 68 E genes from viruses sampled from Vietnamese patients between 1995 and 2009. Strikingly, an episode of genotype replacement was observed, with Asian 1 lineage viruses entirely displacing the previously dominant Asian/American lineage viruses. This genotype replacement event also seems to have occurred within DENV-2 in Thailand and Cambodia, suggestive of a major difference in viral fitness. To determine the cause of this major evolutionary event we compared both the infectivity of the Asian 1 and Asian/American genotypes in mosquitoes and their viraemia levels in humans. Although there was little difference in infectivity in mosquitoes, we observed significantly higher plasma viraemia levels in paediatric patients infected with Asian 1 lineage viruses relative to Asian/American viruses, a phenotype that is predicted to result in a higher probability of human-to-mosquito transmission. These results provide a mechanistic basis to a marked change in the genetic structure of DENV-2 and more broadly underscore that an understanding of DENV evolutionary dynamics can inform the development of vaccines and anti-viral drugs.

    Services to treat tobacco dependence are not readily available to smokers in low-middle income countries (LMICs) where smoking prevalence remains high. We are conducting a cluster randomized controlled trial comparing the effectiveness of two strategies for implementing tobacco use treatment guidelines in 26 community health centers (CHCs) in Viet Nam. Guided by the Consolidated Framework for Implementation Research (CFIR), prior to implementing the trial, we conducted formative research to (1) identify factors that may influence guideline implementation and (2) inform further modifications to the intervention that may be necessary to translate a model of care delivery from a high-income country (HIC) to the local context of a LMIC. We conducted semi-structured qualitative interviews with CHC medical directors, health care providers, and village health workers (VHWs) in eight CHCs (n = 40). Interviews were transcribed verbatim and translated into English. Two qualitative researchers used both deductive (CFIR theory driven) and inductive (open coding) approaches to analysis developed codes and themes relevant to the aims of this study. The interviews explored four out of five CFIR domains (i.e., intervention characteristics, outer setting, inner setting, and individual characteristics) that were relevant to the analysis. Potential facilitators of the intervention included the relative advantage of the intervention compared with current practice (intervention characteristics), awareness of the burden of tobacco use in the population (outer setting), tension for change due to a lack of training and need for skill building and leadership engagement (inner setting), and a strong sense of collective efficacy to provide tobacco cessation services (individual characteristics). Potential barriers included the perception that the intervention was more complex (intervention characteristic) and not necessarily compatible (inner setting) with current workflows and staffing

    After a description of the Vietnamese geography and economy, this report presents the Vietnamese energy system, comments the status and origin of electricity production in this country (shares of hydraulic, gas turbine, coal production, and imports). Then, the author presents the various aspects defined within the electric energy development plan for 2011-2020 with a projection until 2030: development principles, objectives, instructions for production plants and for grids, and investments. He proposes a focus on hydroelectricity (meteorological data regarding precipitations, status and power of existing dams, situation and negotiation about the Mekong, problems associated with the development of hydroelectricity in Vietnam), and a focus on the relationship between nuclear energy and climate change (safety issues due to climate change, nuclear plant projects are postponed, the only strategic choice is a massive exploitation of renewable energies). In the last part, the author discusses predictions regarding energy demand, and the associated planning and programming to face this increasing demand

    Abstract Objective To measure the use of motorcycle helmets in children and to determine the reasons why children wear helmets less often than adults. Methods The frequency of helmet wearing among adults and children was ascertained by trained roadside observers, and randomized road user surveys were completed in four major centres in Viet Nam: Hanoi, Ho Chi Minh City, Can Tho and Da Nang. Survey data on key questions were cross tabulated, and χ² was calculated for significant differences between parents and non-parents (0.05). Findings The frequency of helmet use in the four study locations ranged from 90–99% among adults, from 15–53% among children ≤ 7 years of age, and from 38–53% among children > 7 but ≤ 14. Of the parents surveyed, 67% said the fear of neck injury was the most important reason their children did not wear a helmet. Conclusion Children wear motorcycle helmets much less often than adults. Legislation to penalize adults whose children do not wear motorcycle helmets has been proposed in Viet Nam. Furthermore, ongoing advocacy and social marketing efforts are being made to disseminate information about the safety benefits of helmets to combat erroneous public perceptions. PMID:19551255

    There are many factors affecting the capital costs like: increased plant size, multiple unit construction, improved construct methods, increase the lifetime of plant and so on, and beside is technical to enhancing the safety for NPPs. For the question that whether building a NPP is really economic than other energy resources or not, we will find the answer by comparing the USD per kWh of different energy sources as: nuclear power, coal, oil, hydro natural energy sources. The situation of energy in Vietnam was also mentioned in this paper. Vietnam has an abundant natural resources likes: coal, gas, hydro power etc, but from year 2013 to now Vietnam facing of electricity shortage and to solve the problem, Vietnam Government has chosen nuclear power energy to achieve energy balance between the rate of energy consumption and the ability to energy supply. Eight units will be built in Vietnam and in October 2014 Vietnamese officials have chosen Rosatom's AES-2006 design with VVER-1200/v-491 reactors for country's first nuclear power plant at Ninh Thuan and a second plant should follow based on a partnership with Japan. In this paper, the breakdown of NPP costs is considered. All the costs for building a NPP includes: the investment costs are the largest components (about 60%), fuel costs (15%), O and M costs (25%) and external costs are lower than 1% of the kWh costs. The situation for energy in Vietnam was mentioned with increase annually by 5.5 %, and now the shortage electricity is the big problem in power section. The purpose of this report is to give a general picture to consider the cost of nuclear power. It includes all the costs for building a nuclear power plant like total capital investment costs, production costs, external costs in which the capital investment costs is the largest component of the kWh cost.

    1999-01-01

    The Irradiation Center of the Vietnam Atomic Energy Commission (IC-VAEC) is planning to establish a traceability system for high-dose dosimetry and to provide high-dose standards as a secondary standard dosimetry laboratory (SSDL) level in Vietnam. For countries which do not have a standard dosimetry laboratory, the participation in the International Dose Assurance Service (IDAS) operated by the International Atomic Energy Agency (IAEA) is the most common means to verify own dosimetry performance with a certain uncertainty. This is, however, only one-direction dose intercomparison with evaluation by IAEA including unknown parameter at participant laboratories. The SSDL level laboratory should have traceability as well as compatibility, ability to evaluate uncertainties of its own dosimetry performance by itself In the present paper, we reviewed our dosimetry performance through two-way dose intercomparison studies and self-evaluation of uncertainty in our dosimetry procedure. The performance of silver dichromate dosimeter as reference transfer dosimeter in IC-VAEC was studied through two-way blind dose intercomparison experiments between the IC-VAEC and JAERI. As another channel of dose intercomparison with IAEA, alanine dosimeters issued by IDAS were simultaneously irradiated with the IC-VAEC dichromate dosimeters at IC-VAEC and analyzed by IAEA. Dose intercomparison between IC-VAEC and JAERI results into a good agreement (better than ±2.5%), and IDAS results also show similar agreement within ±3.0%. The uncertainty was self-estimated on the basis of the JAERI alanine dosimetry, and a preliminary value of about 1.86% at a 68% confidence level is established. The results from these intercomparisons and our estimation of the uncertainty are consistent. We hope that our experience is valuable to other countries which do not have dosimetry standard laboratories and/or are planning to establish them. (author)

The presence of SOEs has a direct negative effect on the survival odds of local private firms in the same industry, but there is also an indirect impact on the exit hazard from FDI.

    2013-08-01

    In Cambodia, stroke is not ranked among the top 10 leading causes of death, but infectious disease are among the top three leading causes of death. This finding could be attributed to a lack of awareness among Cambodians of the signs and symptoms of stroke or to poor reporting, incomplete data, lack of neurologists and neurosurgeons, or low accessibility to the hospitals. The only study of stroke in Cambodia is the Prevalence of Non-Communicable Disease Risk Factors in Cambodia survey, which identified several stroke-related risk factors in the population. Tobacco chewing or smoking is the main risk factor for stroke in Cambodia. Traditional therapies, such as oyt pleung (moxibustion) and jup (cupping), are widely practiced for stroke rehabilitation. In Cambodia, there are few neurologists and few important equipment, such as magnetic resonance imaging machines and computed tomography scanners. The Cambodian government should cooperate with the World Health Organization and the United Nations Children's Fund to attract foreign expertise and technologies to treat stroke patients. © 2012 The Authors.

    Cambodia, a country of 14 million inhabitants, was devastated during the Khmer Rouge period and thereafter. The resources of treatment are rare: only one radiotherapy department, renovated in 2003, with an old cobalt machine; few surgeons trained to operate on cancer patients; no hematology; no facilities to use intensive chemotherapy; no nuclear medicine department and no palliative care unit. Cervical cancer incidence is one of the highest in the world, while in men liver cancer ranks first (20% of all male cancers). Cancers are seen at stage 3 or 4 for 70% of patients. There is no prevention program - only a vaccination program against hepatitis B for newborns - and no screening program for cervical cancer or breast cancer. In 2010, oncology, recognized as a full specialty, was created to train the future oncologists on site at the University of Phnom Penh. A new National Cancer Center will be built in 2013 with modern facilities for radiotherapy, medical oncology, hematology and nuclear medicine. Cooperation with foreign countries, especially France, and international organizations has been established and is ongoing. Progress is occurring slowly due to the shortage of money for Cambodian institutions and the lay public. Copyright © 2012 S. Karger AG, Basel.

  15. Myths about AIDS in Cambodia.

    Nariddh, M C

    1994-08-01

    HIV has been reported in the capital city of Cambodia, Phnom Penh, as well as in the northwestern provinces of Banteay Meanchey, Battambang, Pursat, and Kompong Chhnang. Unofficial reports indicate the presence of HIV in three northeastern provinces. According to World Health Organization data, 382 people were infected with HIV in Cambodia as of March 1994, but the national AIDS program estimates that 2000-4000 Cambodians may be HIV-seropositive. Small surveys in 1992 identified HIV infection rates to be 4.5% among patients of sexually transmitted disease (STD) clinics and 9.2% among prostitutes. A seroprevalence rate of 4.3% was found in 1993 among clients of STD clinics and others requesting HIV testing. These rather marked levels of infection exist in Cambodia even though HIV was first identified in the country as recently as 1991 among screened blood from volunteer donors. By December 1993, the rate of positive results from blood donors had increased to 1.97%.; the rate of infection among blood donors is expected to double to approximately 4% in 1994. People in Cambodia variously believe that AIDS is nonexistent, AIDS is a problem of other countries, can be transmitted by mosquitoes, healthy people do not have AIDS, a cure exists for AIDS, AIDS can be contracted only from prostitutes, AIDS is the most severe state of syphilis, and AIDS is only a propaganda ploy of condom producers to market their products. It is therefore proving extremely difficult to convince people that AIDS is a truly threatening disease against which they should protect themselves, especially when symptoms are rarely present during the early stage of infection. Health education campaigns, videos, posters, and accurate reporting in the media will, however, help change minds and hopefully induce HIV-preventive behaviors. Of interest, the article notes that virtually every prostitute in Cambodia has at least two-three STDs.

    The Cambodian National Strategic Plan for Elimination of Malaria aims to move step by step toward elimination of malaria across Cambodia with an initial focus on Plasmodium falciparum malaria before achieving elimination of all forms of malaria, including Plasmodium vivax in 2025. The emergence of artemisinin-resistant P. falciparum in western Cambodia over the last decade has drawn global attention to support the ultimate goal of P. falciparum elimination, whereas the control of P. vivax lags much behind, making the 2025 target gradually less achievable unless greater attention is given to P. vivax elimination in the country. The following review presents in detail the past and current situation regarding P. vivax malaria, activities of the National Malaria Control Program, and interventional measures applied. Constraints and obstacles that can jeopardize our efforts to eliminate this parasite species are discussed. PMID:27708187

    2012-07-01

    Digital Elevation Models (DEMs) are used in many applications in the context of earth sciences such as in topographic mapping, environmental modeling, rainfall-runoff studies, landslide hazard zonation, seismic source modeling, etc. During the last years multitude of scientific applications of Synthetic Aperture Radar Interferometry (InSAR) techniques have evolved. It has been shown that InSAR is an established technique of generating high quality DEMs from space borne and airborne data, and that it has advantages over other methods for the generation of large area DEM. However, the processing of InSAR data is still a challenging task. This paper describes InSAR operational steps and processing chain for DEM generation from Single Look Complex (SLC) SAR data and compare a satellite SAR estimate of surface elevation with a digital elevation model (DEM) from Topography map. The operational steps are performed in three major stages: Data Search, Data Processing, and product Validation. The Data processing stage is further divided into five steps of Data Pre-Processing, Co-registration, Interferogram generation, Phase unwrapping, and Geocoding. The Data processing steps have been tested with ERS 1/2 data using Delft Object-oriented Interferometric (DORIS) InSAR processing software. Results of the outcome of the application of the described processing steps to real data set are presented.

  19. The Impact of Hydrodynamics in Erosion - Deposition Process in Can Gio Mangrove Biosphere Reserve, South Viet Nam

    Science.gov (United States)

    Vo-Luong, H. P.

    2014-12-01

    Can Gio Mangrove Biosphere Reserve is always considered as a friendly green belt to protect and bring up the habitants. However, recently some mangrove areas in the Dong Tranh estuary are being eroded seriously. Based on the field measurements in SW and NE monsoons as well as data of topography changes in 10 years, it is proved that hydrodynamics of waves, tidal currents and riverine currents are the main reasons for erosion-deposition processes at the studied site. The erosion-deposition process changes due to monsoon. The analysed results show that high waves and tidal oscillation cause the increase of the erosion rate in NE monsoon. However, high sediment deposition occurs in SW monsoon due to weak waves and more alluvium from upstream. Many young mangrove trees grow up and develop in the SW monsoon. From the research, it is strongly emphasized the role of mangrove forests in soil retention and energy dissipation.

    Streptococcus suis is a zoonotic cause of severe meningitis and sepsis in humans. We aimed to assess the long-term outcomes in patients who survived S. suis infection, in particular the progress and impact of vestibulocochlear sequelae. This case-control study evaluated outcomes of S. suis infection at discharge and 3 and 9 months post-discharge for 47 prospectively enrolled cases and at 11-34 months for 31 retrospectively enrolled cases. Outcomes in patients were compared to 270 controls matched for age, sex and residency. The prevalence ratio (PR) of moderate-to-complete hearing loss was 5.0(95%CI 3.6-7.1) in cases at discharge, 3.7(2.5-5.4) at 3 months, 3.2(2.2-4.7) at 9 months, and 3.1(2.1-4.4) in retrospective cases compared to controls. Hearing improvement occurred mostly within the first 3 months with a change in hearing level of 11.1%(95%CI 7.0-15.1%) compared to discharge. The PR of vestibular dysfunction was 2.4(95%CI 1.7-3.3) at discharge, 2.2(1.4-3.1) at 3 months, 1.8(1.1-2.5) at 9 months, and 1.8(1.1-2.6) for retrospective cases compared to controls. Cases also indicated more problems with mobility, self-care and usual activities. Both hearing and vestibular impairment were common and persist in cases. Appropriate patient management strategies are needed to reduce the incidence and impact of these sequelae. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Data on tuberculosis (TB) among health care workers (HCW) and TB infection control (TBIC) indicators are rarely available at national level. We assessed multi-year trends in notification data of TB among HCW and explored possible associations with TBIC indicators. Notified TB incidence among HCW and 3 other TBIC indicators were collected annually from all 64 provincial and 3 national TB facilities in Vietnam. Time trends in TB notification between 2009 and 2013 were assessed using linear regression analysis. Multivariate regression models were applied to assess associations between the facility-specific 5-year notification rate and TBIC indicators. Forty-seven (70 %) of 67 facilities contributed data annually over five years; 15 reported at least one HCW with TB in 2009 compared to six in 2013. The TB notification rate dropped from 593 to 197 per 100,000 HCW (p trend  = 0.02). Among 104 TB cases reported, 30 were employed at TB wards, 24 at other clinical wards, ten in the microbiology laboratory, six at the MDR-TB ward, and 34 in other positions. The proportion of facilities with a TBIC plan and focal person remained relatively stable between 70 % and 84 %. The proportion of facilities providing personal protective equipment (PPE) to their staff increased over time. Facilities with a TBIC focal person were 7.6 times more likely to report any TB cases than facilities without a focal person. The TB notification rates among HCW seemed to decrease over time. Availability of PPE increased over the same period. Appointing a TBIC focal person was associated with reporting of TB cases among HCW. It remains unclear whether TBIC measures helped in reduction of the TB notification rates in HCW.

    Dam construction is one of the main factors resulting in riverine sediment changes, which in turn cause river degradation or aggradation downstream. The main objective of this work is to examine the sediment budget affected by a sequence of dams constructed upstream in the lower reach of the Red River. The study is based on the longer-term annual data (1960-2010) with a complementary daily water and sediment data set (2008-2010). The results showed that the stretch of the river changed from sediment surplus (suggesting possible deposition processes) into sediment deficit (possible erosion processes) after the first dam (Thac Ba Dam) was constructed in 1972 and changed back to deposition after the second dam (Hoa Binh Dam) was constructed in 1985. The annual sediment deposition varied between 1.9 Mt/y and 46.7 Mt/y with an annual mean value of 22.9 Mt/y (1985-2010). The sediment deposition at the lower reach of the Red River would accelerate river aggradation which would change river channel capacity in the downstream of the Red River. The depositional processes could be sustained or changed back to erosional processes after more dams (the amount of sediment deposit was much less after the latest two dams Tuyen Quang Dam in 2009 and Sonla Dam in 2010) are constructed, depending on the water and sediment dynamics. This study revealed that the erosional and depositional processes could be shifted for the same stretch of river as affected by a sequence of dams and provides useful insights in river management in order to reduce flood frequency along the lower reach of the Red River.

  4. Vulnerability and Risk of Agro-ecosystems Facing Increased Salinity Intrusion in the Mekong Delta, Viet Nam

    Renaud, F.; Sebesvari, Z.; Nguyen, M. T.; Hagenlocher, M.

    2016-12-01

    The Vietnamese portion of the Mekong Delta increasingly suffers from salinity intrusion in its freshwater system, as exemplified by the historically high salinity levels recorded during the 2016 dry season. Although this exceptional situation was linked to the El Niño phenomena, many factors contribute to an increasing salinization of coastal areas. Salinity intrusion is a natural process in this tidal area but its extent is increasing and projected to worsen due to increased demand for water, diversion/storage of water flows in the Mekong river and its tributaries, land subsidence linked to groundwater over-abstraction, changes in land use and water management in coastal areas, and sea level rise. The Mekong Delta remains predominantly an agricultural landscape which contributes the majority of the rice, aquaculture, and fruit production of the country. These systems will need to be adapted to increased salinity levels. We will present results from two research projects, DeltAdapt and DELTAS, which were designed to allow understanding of, respectively (1) the main drivers of change of agro-ecosystems in coastal areas of the delta and (2) the relative vulnerabilities and risks deltaic social-ecological systems face with respect to various environmental hazards. We used the Global Delta Vulnerability Index developed within the DELTAS project to characterize the vulnerabilities and risks faced by coastal provinces of the delta with respect to salinity intrusion. The analysis allows us to understand which social, economic, and ecological variables index explain the relative vulnerability of the provinces. In addition, drivers of change (e.g. policy, economic, social, environmental) of coastal agro-ecosystems were systematically analyzed through 80 interviews and 7 focus group discussions in the provinces of Kien Giang and Soc Trang within the DeltAdapt project. This was combined with the analysis of Vietnamese policies to determine which are the important drivers of change in the region and how these contribute (or not) to the adaptation of agro-ecosystems facing increased salinity intrusion. By combining these results, we will point to potential policies that could be considered by various authorities to allow for a greater adaptability of agro-ecosystems in the coastal provinces of the region.

    2015-01-01

    Since 2006, reports from China and Viet Nam have alerted of an emergent highly pathogenic variant of porcine reproductive and respiratory syndrome virus (HP-PRRSV) in that region. The frequent occurrence of outbreaks in these countries puts Cambodian pig farms at high risk of infection, but no study had been conducted to investigate the presence of HP-PRRS in Cambodian farms. We investigated the presence of HP-PRRS in medium-scale (semi-commercial) swine farms in the Cambodian southeastern region. Specifically, one province bordering Viet Nam (Takeo) was selected due to the concentration of most semi-commercial farms in that province. A cross-sectional study was carried out, between July and September 2010 to assess whether the prevalence of infection in these farms was indicative of recent spread of PPRSV and to identify risk factors for infection. The number of farms to be sampled was established using methods for Lot Quality Assurance Surveys (LQAS), in order to achieve a pre-established ability to discriminate between two different prevalence settings. The target population comprised all semi-commercial farms in Takeo province from which a random sample of 35 farms was selected. Selected farms were visited and questionnaires administered to gather information on farm characteristics and husbandry practices. Blood samples from individual pigs were collected in each of the study farms and tested for PRRSV, along with a number of other swine respiratory pathogens in order to investigate potential interactions. Our results showed that the virus was already present in Takeo semi-commercial pig population (LQAS herd prevalence ≥85%) at the time of sampling. The presence of sows in the farm and farm density were significantly associated (P<0.05) with the introduction and the presence of PRRS - but this was an unadjusted association as small sample size precluded multivariate analysis. Spatiotemporal description of the supposed pattern of infection revealed that the

    2017-07-01

    Full Text Available Cancer care with curative intent remains difficult to manage in many resource-limited settings such as Cambodia. Cambodia has a small workforce with limited financial and health-care resources resulting in delayed diagnoses and availability of limited therapeutic tools. Thus, palliative care becomes the primary form of care in most cases. Although palliative care is becoming an integral part of medical care in developed countries, this concept remains poorly understood and utilized in developing countries. Angkor Hospital for Children serves a relatively large pediatric population in northern Cambodia. According to the modern definition of palliative care, approximately two-thirds of the patients admitted to the hospital were deemed candidates to receive palliative care. In an effort to develop a pediatric palliative care team utilizing existing resources and intensive training, our focus group recruited already existing teams with different health-care expertise and other motivated members of the hospital. During this process, we have also formed a palliative care training team of local experts to maintain ongoing palliative care education. Feedback from patients and health-care providers confirmed the effectiveness of these efforts. In conclusion, palliative and sustainable care was offered effectively in a resource-limited setting with adequately trained and motivated local providers. In this article, the steps and systems used to overcome challenges in Cambodia are summarized in the hope that our experience urges governmental and non-governmental agencies to support similar initiatives.

    Sunil, Thankam S; Sagna, Marguerite

    2015-10-01

    Childhood malnutrition is a major problem in developing countries, and in Cambodia, it is estimated that approximately 42% of the children are stunted, which is considered to be very high. In the present study, we examined the effects of proximate and socio-economic determinants on childhood malnutrition in Cambodia. In addition, we examined the effects of the changes in these proximate determinants on childhood malnutrition between 2000 and 2005. Our analytical approach included descriptive, logistic regression and decomposition analyses. Separate analyses are estimated for 2000 and 2005 survey. The primary component of the difference in stunting is attributable to the rates component, indicating that the decrease of stunting is due mainly to the decrease in stunting rates between 2000 and 2005. While majority of the differences in childhood malnutrition between 2000 and 2005 can be attributed to differences in the distribution of malnutrition determinants between 2000 and 2005, differences in their effects also showed some significance. © 2013 John Wiley & Sons Ltd.

    Cambodia (now the Khmer Republic), in tropical, humid southeast Asia, has an area of 175,630 km and a population of about 5 million. The Mekong River, one of the world's largest rivers, flows through Cambodia. Also, the Tonle Sap (Grand Lac), a highly productive fresh-water lake, functions as a huge off-channel storage reservoir for flood flow of the Mekong River. Surfacewater discharge in streams and rivers of Cambodia is abundant during the wet season, mid-May through mid-November, when 85 percent of the precipitation falls, but is frequently deficient during the remainder of the year. Annual rainfall ranges from 1,370 mm in the central lowlands to more than 5,000 mm in the mountainous highlands. The mean annual temperature for the country is 27.5?C and the evaporation rate is high. During 1960-63, 1,103 holes were drilled in 16 of the 18 khets (provinces), of which 795 or approximately 72 percent, were productive wells at rates ranging from 1.1 to 2,967 l/min. The productive wells ranged in depth from 2 to 209.4 m and were 23.2 m deep on the average. Mr. Rasmussen ' studied the subsurface geology of Cambodia in considerable detail by examining drillers' logs and constructing nine geologic cross sections. The principal aquifer tapped by drilled wells in Cambodia is the Old Alluvium. In many places, however, dug wells and a few shallow drilled wells obtain water from the Young Alluvium. Sandstone of the Indosinias Formation yields moderate to small quantities of water to wells in a number of places. Also, wells tapping water-bearing basalt have a small to moderate yield. The quality of water is recorded in only a few analyses. The dissolved solids concentrations appear to be generally low so that the water is usable for most purposes without treatment. Some well waters, however, are high in iron and would have to be aerated and filtered before use. In this report, well records are tabulated, and the geology and hydrology is discussed by khets.

    Determining the magnitude of the thalassemia problem in a country is important for implementing a national prevention and control program. In order to acquire accurate thalassemia prevalence data, the gene frequency of α- and β-thalassemia (α- and β-thal) in different regions of a country should be determined. The molecular basis of thalassemia in Cambodia was performed by polymerase chain reaction (PCR)-based techniques in a community-based cross-sectional survey of 1631 unrelated individuals from three regions, Battambang, Preah Vihear and Phnom Penh. Thalassemia mutations were detected in 62.7% of the three studied population of Cambodia. Hb E (HBB: c.79G > A) was the most common β-globin gene mutation with a frequency ranging from 0.139 to 0.331, while the most frequent α-globin gene mutation was the -α(3.7) (rightward) deletion (0.098-0.255). The other frequencies were 0.001-0.003 for β-thal, 0.008-0.011 for α-thal-1 (- -(SEA)), 0.003-0.008 for α-thal-2 [-α(4.2) (leftward deletion)], 0.021-0.044 for Hb Constant Spring (Hb CS, HBA2: c.427T > C) and 0.009-0.036 for Hb Paksé (HBA2: c.429A > T). A regional specific thalassemia gene frequency was observed. Preah Vihear had the highest prevalence of Hb E (55.9%), α-thal-2 (24.0%) and nondeletional α-thal (15.1%), whereas Phnom Penh had the lowest frequency of thalassemia genes. Interestingly, in Preah Vihear, the frequency of Hb Paksé was extremely high (0.036), almost equivalent to that of Hb CS (0.044). Our results indicate the importance of micromapping and epidemiology studies of thalassemia, which will assist in establishing the national prevention and control program in Cambodia.

  11. Brain MR image segmentation using NAMS in pseudo-color.

    2017-12-01

    Image segmentation plays a crucial role in various biomedical applications. In general, the segmentation of brain Magnetic Resonance (MR) images is mainly used to represent the image with several homogeneous regions instead of pixels for surgical analyzing and planning. This paper proposes a new approach for segmenting MR brain images by using pseudo-color based segmentation with Non-symmetry and Anti-packing Model with Squares (NAMS). First of all, the NAMS model is presented. The model can represent the image with sub-patterns to keep the image content and largely reduce the data redundancy. Second, the key idea is proposed that convert the original gray-scale brain MR image into a pseudo-colored image and then segment the pseudo-colored image with NAMS model. The pseudo-colored image can enhance the color contrast in different tissues in brain MR images, which can improve the precision of segmentation as well as directly visual perceptional distinction. Experimental results indicate that compared with other brain MR image segmentation methods, the proposed NAMS based pseudo-color segmentation method performs more excellent in not only segmenting precisely but also saving storage.

    2000-01-01

    During the 1996 AIRSAR Pacific Rim Deployment, data were collected over Angkor in Cambodia. The temples of Angkor date the succession of cities to the 9th-13th century AD, but little is known of its prehistoric habitation. A related area of archaeological debate has been the origin, spiritual meaning and use of the hydraulic constructions in the urban zone. The high resolution, multi-channel capability of AIRSAR, together with the unprecedentedly accurate topography provided by TOPSAR, offer identification and delineation of these features. Examples include previously unrecorded circular earthworks around circular village sites, detection of unrecorded earthwork dykes, reservoirs and canal features, and of temple sites located some distance from the main temple complex at Angkor.

We report the first series of hospitalized pulmonary melioidosis cases identified in Cambodia describing clinical characteristics and outcomes. Methods We characterized cases of acute lower respiratory infections (ALRI that were identified through surveillance in two provincial hospitals. Severity was defined by systolic blood pressure, cardiac frequency, respiratory rate, oxygen saturation and body temperature. B. pseudomallei was detected in sputum or blood cultures and confirmed by API20NE gallery. We followed up these cases between 6 months and 2 years after hospital discharge to assess the cost-of-illness and long-term outcome. Results During April 2007 - January 2010, 39 ALRI cases had melioidosis, of which three aged ≤2 years; the median age was 46 years and 56.4% were males. A close contact with soil and water was identified in 30 patients (76.9%. Pneumonia was the main radiological feature (82.3%. Eleven patients were severe cases. Twenty-four (61.5% patients died including 13 who died within 61 days after discharge. Of the deceased, 23 did not receive any antibiotics effective against B. pseudomallei. Effective drugs that were available did not include ceftazidime. Mean total illness-related costs was of US$65 (range $25-$5000. Almost two-thirds (61.5% incurred debt and 28.2% sold land or other belongings to pay illness-related costs. Conclusions The observed high fatality rate is likely explained by the lack or limited access to efficient antibiotics and under-recognition of the disease among clinicians, which led to inappropriate therapy.

    This paper describes a rapid assessment of Cambodia's current system for regulating its health professions. The assessment forms part of a co-design process to set strategic priorities for strengthening health profession regulation to improve the quality and safety of health services. A health system approach for strengthening health professions' regulation is underway and aims to support the Government of Cambodia's plans for scaling up its health workforce, improving health services' safety and quality, and meeting its Association of South East Asian Nations (ASEAN) obligations to facilitate trade in health care services. The assessment used a mixed methods approach including: A desktop review of key laws, plans, reports and other documents relating to the regulation of the health professions in Cambodia (medicine, dentistry, midwifery, nursing and pharmacy); Key informant interviews with stakeholders in Cambodia (The term "stakeholders" refers to government officials, people working on health professional regulation, people working for the various health worker training institutions and health workers at the national and provincial level); Surveys and questionnaires to assess Cambodian stakeholder knowledge of regulation; Self-assessments by members of the five Cambodian regulatory councils regarding key capacities and activities of high-performing regulatory bodies; and A rapid literature review to identify: The key functions of health professional regulation; The key issues affecting the Cambodian health sector (including relevant developments in the wider ASEAN region); and "Smart" health profession regulation practices of possible relevance to Cambodia. We found that the current regulatory system only partially meets Cambodia's needs. A number of key regulatory functions are being performed, but overall, the current system was not designed with Cambodia's specific needs in mind. The existing system is also overly complex, with considerable duplication and

    Abstract In the wake of avian flu outbreaks in 2004, Cambodia received $45 million in commitments from international donors to help combat the spread of animal and human influenza, particularly avian influenza (H5N1). How countries leverage foreign aid to address the specific needs of donors and the endemic needs of the nation is a complex and nuanced issue throughout the developing world. Cambodia is a particularly compelling study in pandemic preparedness and the management of avian influenza because of its multilayered network of competing local, national, and global needs, and because the level of aid in Cambodia represents approximately $2.65 million per human case-a disproportionately high number when compared with neighbors Vietnam and Indonesia. This paper examines how the Cambodian government has made use of animal and human influenza funds to protect (or fail to protect) its citizens and the global community. It asks how effective donor and government responses were to combating avian influenza in Cambodia, and what improvements could be made at the local and international level to help prepare for and respond to future outbreaks. Based on original interviews, a field survey of policy stakeholders, and detailed examination of Cambodia's health infrastructure and policies, the findings illustrate that while pandemic preparedness has shown improvements since 2004, new outbreaks and human fatalities accelerated in 2011, and more work needs to be done to align the specific goals of funders with the endemic needs of developing nations.

    Acinetobacter baumannii is an important cause of multidrug-resistant hospital acquired infections in the world. Here, we investigate the presence of NDM-1 and other carbapenemases among carbapenem-resistant A. baumannii isolated between August 2010 and December 2014 from three large hospitals in Hanoi, Vietnam. We identified 23/582 isolates (4 %) (11 from hospital A, five from hospital B, and seven from hospital C) that were NDM-1 positive, and among them 18 carried additional carbapenemase genes, including seven isolates carrying NDM-1, IMP-1, and OXA-58 with high MICs for carbapenems. Genotyping indicated that NDM-1 carrying A. baumannii have expanded clonally in these hospitals. Five new STs (ST1135, ST1136, ST1137, ST1138, and ST1139) were identified. One isolate carried NDM-1 on a plasmid belonging to the N-repA replicon type; no NDM-1-positive plasmids were identified in the other isolates. We have shown the extent of the carbapenem resistance and the local clonal spread of A. baumannii carrying NDM-1 in these hospitals; coexistence of NDM-1 and IMP-1 is reported for the first time from Vietnam here, and this will further seriously limit future therapeutic options.

    This report is the result of a survey on 564 cows subjected to artificial insemination (AI) from March 1995 to March 1996 in 4 districts around Ho Chi Minh City. Four inseminators filled in questionnaires relating to farms, semen batches, cows and inseminations done. Milk samples were collected and analysed for progesterone by radioimmunoassay (RIA). All raw data were stored and analysed by the computer program AIDA (Artificial Insemination Database Application). Conception rate at first service (FSCR) was 61.7% and overall conception rate (OCR) was 68.4%. The intervals from calving to first service (CSI) and calving to conception (CCI) were 108 days 119 days respectively. Cows with lower percentage of Holstein-Friesian (HF) blood had shorter CSI and CCI than those with higher percentage of HF blood. Other factors which influenced OCR, CSI and CCI were parity, high milk yield (>20 L/cow/day), inappropriate heat signs, slight degree of uterine tone, feeding without green grass, too early or too late intervals from heat signs to AI, time of AI and difficulty in passage of AI pipette. Progesterone measurement in 796 sets of milk samples indicated that AI in 546 cows (68.6%) resulted in conception and they were subsequently diagnosed pregnant, while 24 animals (3%) conceived but underwent late embryo mortality. In 146 cows (18.3%) AI was done in the follicular phase but conception did not occur. There were 73 cows (9.1%) where progesterone values were intermediate (1-3 nmol/L). Ninety-four Holstein crossbred cows (F1 and F2) were assigned into three groups by different metabolisable energy (ME) ratios between demand and supply in order to determine effect of nutritive value of rations on reproduction. The cows in ME-balanced group were also divided into two sub-groups by different quantity of green grass in the ration to evaluate influence of the latter on fertility. Results showed that only cows fed with balanced rations in ME achieved good fertility (calving to first heat 59 days, CSI 74 days, CCI 96 days and services/conception 1.63). Moreover, when the feed fully provided ME and green grass (≥20 kg/head/day) reproductive performance increased considerably (calving to first heat reduced to 50 days, CSI to 64 days, CCI to 82 days and services/conception to 1.4).

    This study aims to characterize household trends in access to improved water sources and sanitaton in Chi Linh Town, Hai Duong Province, Vietnam, and to identify factors affecting those trends. Data were extracted from the Chi Linh Health and Demographic Surveillance System (CHILILAB HDSS) database from 2004-2014, which included household access to improved water sources, household access to improved sanitation, and household demographic data. Descriptive statistical analysis and multinominal logistic regression were used. The results showed that over a 10-year period (2004-2014), the proportion of households with access to improved water and improved sanitation increased by 3.7% and 28.3%, respectively. As such, the 2015 Millennium Development Goal targets for safe drinking water and basic sanitation were met. However, 13.5% of households still had unimproved water and sanitation. People who are retired, work in trade or services, or other occupations were 1.49, 1.97, and 1.34 times more likely to have access to improved water and sanitation facilities than farming households, respectively ( p < 0.001). Households living in urban areas were 1.84 times more likely than those living in rural areas to have access to improved water sources and improved sanitation facilities (OR =1.84; 95% CI = 1.73-1.96). Non-poor households were 2.12 times more likely to have access to improved water sources and improved sanitation facilities compared to the poor group (OR = 2.12; 95% CI = 2.00-2.25). More efforts are required to increase household access to both improved water and sanitation in Chi Linh Town, focusing on the 13.5% of households currently without access. Similar to situations observed elsewhere in Vietnam and other low- and middle- income countries, there is a need to address socio-economic factors that are associated with inadequate access to improved water sources and sanitation facilities.

    Aflatoxins, fumonisins and ochratoxin A that contaminate various agricultural commodities are considered of significant toxicity and potent human carcinogens. This study took a total dietary study approach and estimated the dietary exposure of these mycotoxins for adults living in Lao Cai province, Vietnam. A total of 42 composite food samples representing 1134 individual food samples were prepared according to normal household practices and analysed for the three mycotoxins. Results showed that the dietary exposure to aflatoxin B1 (39.4 ng/kg bw/day) and ochratoxin A (18.7 ng/kg bw/day) were much higher than recommended provisional tolerable daily intake (PTDI) values mainly due to contaminated cereals and meat. The exposure to total fumonisins (1400 ng/kg bw/day) was typically lower than the PTDI value (2000 ng/kg bw/day). The estimated risk of liver cancer associated with exposure to aflatoxin B1 was 2.7 cases/100,000 person/year. Margin of exposure (MOE) of renal cancer linked to ochratoxin A and liver cancer associated with fumonisins were 1124 and 1954, respectively indicating risk levels of public health concern. Further studies are needed to evaluate the efficiency of technical solutions which could reduce mycotoxin contamination as well as to determine the health effects of the co-exposure to different types of mycotoxins.

    The use of ERTS imagery for water resources planning in the lower Mekong Basin relates to three major issues: (1) it complements data from areas, which have been inaccessible in the past because of security; this concerns mainly forest cover of the watersheds, and geological features, (2) it refines ground surveys; this concerns mainly land forms, and soils of existing and planned irrigation perimeters, and (3) it provides new information, which would be almost or entirely impossible to detect with ground surveys or conventional photography; this concerns the mechanism of flooding and drainage of the delta; siltation of the Great Lake and mapping of acidity, possibly also of salinity, in the lower delta; sedimentation and fisheries in the Mekong Delta estuarine areas.

    SummaryAnalyses of water quality and flow regime in combination with laboratory studies and ecological modelling were used to assess the water quality impact of pollution from to To Lich River that drains through Hanoi City and greatly contaminates the Nhue River. With an average discharge of 26.2 m 3/s, the Nhue River receives about 5.8 m 3/s of untreated domestic water from the city's main open-air-sewer - the To Lich River. The studies during 2002-2003 showed high concentrations of BOD (70 mg O 2/l), DOC (15 mg C/l), coliform (2.4e 6 MNP/100 ml), total phosphorus (3.5 mg P/l), and total nitrogen (31.6 mg N/l) in the To Lich, while DO level was less than 1 mg O 2/l. Such high loads of untreated wastewater impacted water quality in the Nhue River where DO decreased at times to as low as 1 mg O 2/l. The accumulation of particulate organic matter and micro-organisms in the sediments of the Nhue represented substantial sources of nutrients and sinks for DO. They are also considerable production of dissolved carbon dioxide at concentrations up to two orders of magnitude higher than pressure. Such pressures ( EpCO 2) are expected in polluted environments, but the results presented here are new for Vietnam and much of developing countries. A number of factors linked to field monitoring and laboratory measurements clearly indicate the importance of autotrophic over heterotrophic biological processes and sediments. An ecological model for management purposes has been developed that reliably estimates of the pollutant loads. An opportunity was taken to examine the changing impacts and processes when the To Lich was diverted from the Nhue. The monitoring and modelling of this opportunity showed low dissolved oxygen levels even if the impact from the To Lich was lessened. Alternatives are proposed to alleviate problems of water quality in the Nhue. It is concluded that the treatment of the To Lich River's water is highly recommended; otherwise a reduction to one third of current wastewater discharge is needed to bring water quality back to the environmental standard.

    In a context with limited attention to mental health and prevalent sexual prejudice, valid measurements are a key first step to understanding the psychological suffering of sexual minority populations. We adapted the Patient Health Questionnaire as a depressive symptom severity measure for Vietnamese sexual minority women, ensuring its cultural relevance and suitability for internet-based research. Psychometric evaluation found that the scale is mostly unidimensional and has good convergent validity, good external construct validity, and excellent reliability. The sample's high endorsement of scale items emphasizes the need to study minority stress and mental health in this population.

    Full Text Available Abstract Background Rural-to-urban migration involves a high proportion of females because job opportunities for female migrants have increased in urban industrial areas. Those who migrate may be healthier than those staying in the village and they may benefit from better health care services at destination, but the 'healthy' effect can be reversed at destination due to migration-related health risk factors. The study aimed to explore the need for health care services for reproductive tract infections (RTIs among female migrants working in the Sai Dong industrial zone as well as their services utilization. Methods The cross sectional study employed a mixed method approach. A cohort of 300 female migrants was interviewed to collect quantitative data. Two focus groups and 20 in-depth interviews were conducted to collect qualitative data. We have used frequency and cross-tabulation techniques to analyze the quantitative data and the qualitative data was used to triangulate and to provide more in-depth information. Results The needs for health care services for RTI were high as 25% of participants had RTI syndromes. Only 21.6% of female migrants having RTI syndromes ever seek helps for health care services. Barriers preventing migrants to access services were traditional values, long working hours, lack of information, and high cost of services. Employers had limited interests in reproductive health of female migrants, and there was ineffective collaboration between the local health system and enterprises. These barriers were partly caused by lack of health promotion programs suitable for migrants. Most respondents needed more information on RTIs and preferred to receive these from their employers since they commonly work shifts - and spend most of their day time at work. Conclusion While RTIs are a common health problem among female migrant workers in industrial zones, female migrants had many obstacles in accessing RTI care services. The findings from this study will help to design intervention models for RTI among this vulnerable group such as communication for behavioural impact of RTI health care, fostered collaboration between local health care services and employer enterprises, and on-site service (e.g. local or enterprise health clinics strengthening.

    Full Text Available In the millennium leading up to its days of glory and regional leadership under the iconic Angkor empire, and even in the centuries of dependence since, Cambodia has often benefited significantly from the influence of its patrons, starting with traders from India who sailed up the Mekong at the beginning of a magnificent water transport system including an inland sea. Most recently such benefits have been from global and multilateral sources. Equally, due to its pivotal strategic location at the centre of the South-East corner of Asia, Cambodia has also suffered, at times enormously, from the competing influences of a plethora of well-intentioned but radically different influences: religious, cultural, linguistic, imperial, political, ideological and educational. This article will review the educational system of Cambodia and the issues that come with achieving political and now psychological freedom from dependence on foreign dominance and tutelage.

    Full Text Available Employing education production function approach, this article investigates the influences of school and pupil background factors on academic achievement of primary school pupils in Cambodia. Based on achievement data of 1,080 Grade 6 pupils from one rural and one semi-urban area, the study reveals that school and teacher quality exerts a considerable effect on pupils’ performance. Teachers’ experience and teacher guides are positively correlated with academic achievement, while instructional time loss is significantly associated with poor performance. In light of these results, policies to boost academic achievement of primary school pupils in Cambodia are discussed.

East Asian historians Kathlene Baldanza and Bradley Camp Davis provide excellent, detailed studies of Vietnam and Beijing as they worked to resolve issues in the territory separating them. Although in the early modern age, the scholar-officials of both lands shared a Confucian ideology and practice, the asymmetric relationship between the two lands (Womack 2006 engendered very different perspectives on each side of the frontier.

Each of the authors also gives us a view of the Vietnamese dynasties of those ages: the Tran (1225–1400, the Le (1428–1527, 1592–1788, the Mac (1528–1592 of Dai Viet, and the Nguyen (1802–1945 of Vietnam. The two authors bring us into their scenes through engagement with a variety of primary sources. Baldanza does a masterful job with contemporary Vietnamese and Chinese documents (both in Chinese characters, mining the interactions between the two. Davis, in a more recent setting, does a fine job bringing local oral traditions together with official imperial documents of both Hue and Beijing, as well as official and nonofficial French documentation. Both books offer a rich mixture of analysis of the contemporary textual record, written and oral

    2015-01-01

    This study examines the risk characteristics of fatal motorcycle crashes in Cambodia over a 5-year period (2007-2011). Secondary data analyses were conducted using the Cambodia Road Crash and Victim Information System, the only comprehensive and integrated road crash surveillance system in the country. Researchers from the Centers for Disease Control and Prevention and Handicap International found that (1) males are dying in motorcycle crashes roughly seven times more frequently than females; (2) motorcyclist fatalities increased by about 30% from 2007 to 2011; (3) the motorcyclist death rates per 100,000 population increased from 7.4 to 8.7 deaths from 2007 to 2011; and (4) speed-related crashes and not wearing motorcycle helmet were commonly reported for motorcyclist fatalities at approximately 50% and over 80% through the study years, respectively. Additionally, this study highlights that Cambodia has the highest motorcycle death rate in South-East Asia, far surpassing Thailand, Malaysia, and Myanmar. By recognising the patterns of fatal motorcycle crashes in Cambodia, local road-safety champions and stakeholders can design targeted interventions and preventative measures to improve road safety among motorcyclists.

    A 2014 national assessment of salt iodization coverage in Cambodia found that 62% of samples were non-iodized, suggesting a significant decline in daily iodine intakes. The Cambodian Micronutrient Survey conducted in 2014 (CMNS-2014) permitted obtaining national data on urinary iodine concentrations (UIC) to assess iodine status and whether iodized salt use had an impact. Urine samples were collected from mothers (n = 736) and children (n = 950). The median UIC was 63 µg/L and 72 µg/L in mothers and children respectively. More than 60% of mothers and their children had a UIC Cambodia. It is essential for the government to enhance enforcement of the iodized salt legislation, and implement short term strategies, such as iodine supplementation, to prevent an increase of severe complications due to iodine deficiency in the Cambodian population.

    2010-06-01

    We describe the first cases of pediatric melioidosis in Cambodia. Thirty-nine cases were diagnosed at the Angkor Hospital for Children, Siem Reap, between October 2005 and December 2008 after the introduction of microbiology capabilities. Median age was 7.8 years (range = 1.6-16.2 years), 15 cases were male (38%), and 4 cases had pre-existing conditions that may have pre-disposed the patient to melioidosis. Infection was localized in 27 cases (69%) and disseminated in 12 cases (31%). Eleven cases (28%) were treated as outpatients, and 28 (72%) cases were admitted. Eight children (21%) died a median of 2 days after admission; seven deaths were attributable to melioidosis, all of which occurred in children receiving suboptimal antimicrobial therapy and before bacteriological culture results were available. Our findings indicate the need for heightened awareness of melioidosis in Cambodia, and they have led us to review microbiology procedures and antimicrobial prescribing of suspected and confirmed cases.

  10. Influence of Climate Factors on Rice Yields in Cambodia

    2017-12-01

    Full Text Available Temperature and precipitation have been known as the key determinant factors to affect rice production in climate change. In this study, the relationship between climate variables and rice yields during 1993–2012 in Cambodia was analyzed and evaluated. The Ordinary Least Squares analysis was applied to examine the relationship of three climate variables (TCV including maximum temperature, minimum temperature and rainfall against seasonal rice yields. By this period, a remarkable increasing trend of annual temperature was observed whilst rainfall was not significantly changed. The TCV explains approximately 63% and 56% of the variability of rice yields in wet and dry seasons, respectively. It is found that in Cambodia, non-climate factors such as fertilizers, water, cultivars, and soil fertility cause 40% variation to rice yields, whereas the remaining 60% can be influenced by climate variability. The levels of temperature difference (LTD between maximum and minimum temperatures of the wet season (WS and dry season (DS were 7.0 and 8.6 oC, respectively. The lower value of LTD may cause the reduction of rice in WS (2.2 tons/ha as compared to that of DS (3.0 tons/ha. Rice yield has increased 50.5% and 33.8% in DS and WS, respectively, may due to the improvement of rice cultivation practices in Cambodia such as the better use of fertilizers, pest and weed control, and irrigation, and more effective rice cultivated protocol, as the increased trend of temperature may detrimentally affect rice yield. The breeding of heat and drought tolerance rice varieties and development of irrigation system are effective to reduce the negative influence from climate change to rice production in Cambodia.

    Full Text Available Abstract Background There is little information about influenza disease among the Cambodian population. To better understand the dynamics of influenza in Cambodia, the Cambodian National Influenza Center (NIC was established in August 2006. To continuously monitor influenza activity, a hospital based sentinel surveillance system for ILI (influenza like illness with a weekly reporting and sampling scheme was established in five sites in 2006. In addition, hospital based surveillance of acute lower respiratory infection (ALRI cases was established in 2 sites. Methods The sentinel sites collect weekly epidemiological data on ILI patients fulfilling the case definition, and take naso-pharyngeal specimens from a defined number of cases per week. The samples are tested in the Virology Unit at the Institut Pasteur in Phnom Penh. From each sample viral RNA was extracted and amplified by a multiplex RT-PCR detecting simultaneously influenza A and influenza B virus. Influenza A viruses were then subtyped and analyzed by hemagglutination inhibition assay. Samples collected by the ALRI system were tested with the same approach. Results From 2006 to 2008, influenza circulation was observed mainly from June to December, with a clear seasonal peak in October shown in the data from 2008. Conclusion Influenza activity in Cambodia occurred during the rainy season, from June to December, and ended before the cool season (extending usually from December to February. Although Cambodia is a tropical country geographically located in the northern hemisphere, influenza activity has a southern hemisphere transmission pattern. Together with the antigenic analysis of the circulating strains, it is now possible to give better influenza vaccination recommendation for Cambodia.

    Typhoid fever was confirmed by positive blood culture in 5 (3.7%) of 134 febrile children hospitalized in Cambodia. Typhoid was suspected in an additional 25 (18.7 %) blood culture-negative children based on: a positive immunoglobulin M lateral flow assay (IgMFA) (16); a positive polymerase chain reaction (PCR) for Salmonella typhi (2); or clinical assessment (7). The specificity of the IgMFA and PCR assays requires further study.

  14. Indicators for sustainable tourism: The case of Cambodia

    Directory of Open Access Journals (Sweden)

    Nhep Tinat

    2015-03-01

    Full Text Available Most research on tourism in Cambodia so far has focused on growth. There is very limited research on indicators for sustainability. A failure to create indicators for sustainable tourism may lead to short-term growth but the country will suffer in the long run. Sustainability really matters in tourism especially in a new destination like Cambodia. Cambodia has no clear indicators determining tourism sustainability. Cambodia’s tourism is remarkably flourishing, but behind this growth some challenges exist: Cultural and environmental impacts, economic leakage, sex tourism, drug trafficking and disease transmission. These concern tourism sustainability. This research intends to fill a significant gap regarding challenges hampering sustainable tourism, particularly creating indicators, by studying the activities of Cambodia’s tourism. The aim is to contribute to developing more comprehensive policies and measures that address problems by drawing on the activities and perspectives of the country’s tourism stakeholders: These include public and private actors, NGOs, local people and tourists.

  15. A Multimedia Approach to ODL for Agricultural Training in Cambodia

    Directory of Open Access Journals (Sweden)

    Helena Grunfeld

    2013-03-01

    Full Text Available Open distance learning (ODL has long been an important option for formal and non-formal education (NFE in most developed and developing countries, but less so in post-conflict countries, including Cambodia. However, in Cambodia there is now greater awareness that ODL can complement traditional face-to-face educational approaches, particularly as there is a shortage of teachers in the country. Thus, understanding how ODL can achieve learning and other objectives has important implications for both formal education and NFE. If it can be found to be effective, ODL has the potential of reaching a large number of people at comparatively lower average costs. This paper reports on a project where the same content was taught to farmers in Cambodia via traditional face-to-face and via ODL and compares outcomes between the different training methods. Exploring the extent to which farmers had adopted new farm practices taught in the course, our results indicate that the outcomes did not vary considerably between those trained using the different approaches.

  16. The commercialization of traditional medicine in modern Cambodia.

    2018-01-01

    Globally, traditional medicine has long been used to address relatively common illness, mental ill health and during childbirth and post-natal care. However, traditional medicine is primarily provided by the private sector and it is unclear how far expenditures on traditional medicine contribute to household impoverishment. A life history method was used to understand the health seeking experience of 24 households over the last 60 years in Cambodia, a country with high out-of-pocket expenditures for health. The life histories suggest that traditional medicine in Cambodia has been undergoing a process of commercialization, with significant impacts on poor households. In the earlier lives of respondents, payments for traditional medicine were reported to have been flexible, voluntary or appropriate to patients' financial means. In contrast, contemporary practitioners appear to seek immediate cash payments that have frequently led to considerable debt and asset sales by traditional medicine users. Given traditional medicine's popularity as a source of treatment in Cambodia and its potential to contribute to household impoverishment, we suggest that it needs to be included in a national conversation about achieving Universal Health Coverage in the country. © The Author 2017.

    2018-04-01

    This cross-sectional study examined perceived level of importance, perceived level of competency in extension core competencies, and whether and how perceptions of competency vary by respondents' demographics; ascertained gaps in competency, if any; and identified ways for agricultural development professionals in Cambodia to acquire core competencies. Data were collected using a group-administered survey among 39 agricultural development professionals participating in a national workshop in December 2015. The survey consisted of 48 competencies representing eight core competencies, and each competency had level of importance and level of competency parts. The findings show that extension workers in Cambodia deemed all competencies highly or very highly important to their extension work; however, their perceived level of competency in those competencies appeared not to meet the expectations. The level of competency in all but communication skills and diversity significantly differed by gender but not by age and experience. Respondents indicated all four methods-preservice, in-service, basic induction training, and participation in seminars, workshops, and webinars-equally appropriate to acquire core competencies. The findings imply that the agricultural development authority in Cambodia should review, update, or design extension education curricula incorporating the competencies highlighted in this study and train its extension cadres on those competencies.

  7. The unfinished health agenda: Neonatal mortality in Cambodia.

    Directory of Open Access Journals (Sweden)

    Rathmony Hong

    Full Text Available Reduction of neonatal and under-five mortality rates remains a primary target in the achievement of universal health goals, as evident in renewed investments of Sustainable Development Goals. Various studies attribute declines in mortality to the combined effects of improvements in health care practices and changes in socio-economic factors. Since the early nineties, Cambodia has managed to evolve from a country devastated by war to a nation soon to enter the group of middle income countries. Cambodia's development efforts are reflected in some remarkable health outcomes such as a significant decline in child mortality rates and the early achievement of related Millennium Development Goals. An achievement acknowledged through the inclusion of Cambodia as one of the ten fast-track countries in the Partnership for Maternal, Newborn and Child Health. This study aims to highlight findings from the field so to provide evidence for future programming and policy efforts. It will be argued that to foster further advances in health, Cambodia will need to keep neonatal survival and health high on the agenda and tackle exacerbating inequities that arise from a pluralistic health system with considerable regional differences and socio-economic disparities.Data was drawn from Demographic Health Surveys (2000, 2005, 2010, 2014.

With a total area of 69,898 square miles and population of 15,458,332, Cambodia’s population density has steadily increased since 1980. The country’s annual rate of urbanization is 2.65 %. As of 2014, 20.5% of the population lives in an urban setting. The estimated population growth rate is 1.63% (1. The capital of Cambodia is Phnom Penh, which is located in the southern part of the country. Other major cities include Battambang and Siem Reap, both of which have populations over 150,000. There are officially 24 provinces and one municipality (Phnom Penh. However, many consider Phnom Penh to be its own province. As a result, some research puts the number of Cambodian provinces at 25. The climate is tropical with two seasons: monsoon season (May to November and dry season (December to April. Temperatures range from approximately 70 to 95°F. Cambodia’s economy largely depends on the garment industry, tourism, construction, real estate and agriculture. Cambodia gained independence from France in 1953 and was first ruled by a constitutional monarchy under King Norodom Sihanouk. After a five-year struggle starting in 1970, the Khmer Rouge captured Phnom Penh in 1975. Pol Pot, the leader of the Khmer Rouge, oversaw a brutal regime that, through executions and forced labor, was responsible for the deaths of at least 1.5 million Cambodians. The Vietnamese drove out the Khmer Rouge in 1979. After years of Vietnamese occupation, the 1991 Paris Peace Accords established a ceasefire and a democratic framework for the country. By 1993 elections established a new coalition government; yet, political instability and violence persisted throughout the 1990s. Cambodia most recently held elections in 2013, as a multiparty democracy under a constitutional monarchy.The devastation caused by the Khmer Rouge has had long

    Full Text Available Like many families who were on the “wrong” side of the Việt Nam war, my family history has effectively been “displaced” from official discourse in Việt Nam when the country was “reunified” in 1975, as well as in the discourse of public history in the U.S. which has overwhelmingly emphasized the “lessons” of the “American Experience” in Việt Nam. Using my family history as an index of historical processes, I hope to introduce windows on the continuities of what noncommunist Vietnamese do and think. My family folklore is utilized as a way to create opportunities for other non-communist Vietnamese here and elsewhere to connect, articulate, or remind them of a pattern from the past that can provide a contemporary coherence with an ethic workable for the future.

    Cambodia has 57% forest cover, the second highest in the Greater Mekong region, and a high deforestation rate (1.2%/year, 2005-2010). Community forestry (CF) has been proposed as a way to reduce deforestation and support livelihoods through local management of forests. CF is expanding rapidly in Cambodia. The National Forests Program aims to designate one million hectares of forest to CF by 2030. However, the effectiveness of CF in conservation is not clear due to a global lack of controlled comparisons, multiple meanings of CF, and the context-specific nature of CF implementation. We assessed the effectiveness of CF by comparing 9 CF sites with paired controls in state production forest in the area of Prey Long forest, Cambodia. We assessed forest condition in 18-20 randomly placed variable-radius plots and fixed-area regeneration plots. We surveyed 10% of households in each of the 9 CF villages to determine the proportion that used forest products, as a measure of household dependence on the forest. CF sites had fewer signs of anthropogenic damage (cut stems, stumps, and burned trees), higher aboveground biomass, more regenerating stems, and reduced canopy openness than control areas. Abundance of economically valuable species, however, was higher in control sites. We used survey results and geographic parameters to model factors affecting CF outcomes. Interaction between management type, CF or control, and forest dependence indicated that CF was more effective in cases where the community relied on forest products for subsistence use and income. © 2014 Society for Conservation Biology.

    Though the consequences of nutritional iodine deficiency have been known for a long time, in Cambodia its elimination has only become a priority in the last 18 years. The Royal Government of Cambodia initiated the National Sub-Committee for Control of Iodine Deficiency Disorders in 1996 to fight this problem. Using three different surveys providing information across all provinces, we examined the compliance of salt iodization in Cambodia over the last 6 years. Salt samples from the 24 provinces were collect at the household level in 2008 (n = 566) and 2011 (n = 1275) and at the market level in 2014 (n = 1862) and analysed through a wavelength spectrophotometer for iodine content. According to the samples collected, the median iodine content significantly dropped from 22 mg/kg (25th/75th percentile: 2/37 mg/kg) in 2011 to 0 mg/kg in 2014 (25th/75th percentile: 0/8.9 mg/kg) (p < 0.001). The proportion of non-iodized salt within our collected salt drastically increased from 22% in 2011 to 62% in 2014 (p < 0.001). Since the international organizations ceased to support the procurement of iodine, the prevalence of salt compliant with the Cambodian declined within our samples. To date, the current levels of iodine added to tested salt are unsatisfactory as 92% of those salts do not meet the government requirements (99.6% of the coarse salt and 82.4% of the fine salt). This inappropriate iodization could illustrate the lack of periodic monitoring and enforcement from government entities. Therefore, government quality inspection should be reinforced to reduce the quantity of salt not meeting the national requirement.

    The Lower Mekong River flows through Cambodia, where forests cover ~60% of the country and are believed to have a marked effect on the water cycle. These tropical seasonal forests in the Cambodian flat lands are very precious in the Indochinese Peninsula as few forests of this type remain. However, few hydrological observations have been conducted in these areas. In Cambodia, deciduous and evergreen forests make up 42% and 33% of the total forest area, respectively. We established experimental watersheds both in deciduous and evergreen forests containing meteorological observation towers in Cambodia and collected various observational data since 2003 (O'Krieng, deciduous forest watershed including a 30-m-high observation tower, 2,245 km2; Stung Chinit, evergreen forest watershed including a 60-m-high observation tower, 3,700 km2 including three small watersheds). The basic data from these sites included various kinds of information related to the composition of vegetation, soil characteristics, etc. Hydrologic data was collected and linked to the above data; the main hydrologic research results follow. The water budget for each watershed was determined using an observational rainfall and runoff dataset. The evapotranspiration rate in an evergreen forest was obtained using various observational methods including the Bowen energy-balance ratio and the bandpass eddy covariance method. The annual evapotranspiration of evergreen forests, estimated using the Bowen energy-balance ratio method and water balance, was about 1100-1200 mm, corresponding to 70-80% of annual rainfall. While considering the importance of the presence of evergreen forest, we conducted sap flow measurements to analyze the transpiration process that maintains water uptake through root systems that reach to depths exceeding 8 m. Characteristics of the evaporation from the forest floor that form an important element of the evaporation system were estimated in both evergreen and deciduous forests.

  15. The political sublime. reading Kok Nam, Mozambican photographer (1939-2012

    Rui Assubuji

    Full Text Available Kok Nam began his photographic career at Studio Focus in Lourenco Marques in the 1950s, graduated to the newspaper Noticias and joined Tempo magazine in the early 1970s. Most recently he worked at the journal Savana as a photojournalist and later director. This article opens with an account of the relationship that developed between Kok Nam and the late President Samora Machel, starting with the photographer's portrait of Machel in Nachingwea in November 1974 before Independence. It traces an arc through the Popular Republic (1976-1990 from political revelation at its inception to the difficult years of civil war and Machel's death in the plane crash at Mbuzini in 1986. The article then engages in a series of photo-commentaries across a selection of Kok Nam's photographs, several published in their time but others selected retrospectively by Kok Nam for later exhibition and circulation. The approach taken is that of 'association', exploring the connections between the photographs, their histories both then and in the intervening years and other artifacts and mediums of cultural expression that deal with similar issues or signifiers picked up in the images. Among the signifiers picked up in the article are soldiers, pigs, feet, empty villages, washing, doves and bridges. The central argument is that Kok Nam participated with many others in a kind of collective hallucination during the Popular Republic, caught up in the 'political sublime'. Later Kok Nam shows many signs of a photographic 'second thinking' that sought out a more delicate sublime in his own archive.

    The Asia-Pacific region is thought to be severely affected by diabetes. However, reliable, standardised data on prevalence and characteristics of glucose intolerance in Asian populations remain sparse. We describe the results of two field surveys undertaken in Cambodia in 2004. 2246 randomly selected adults aged 25 years and older were examined in two communities, one rural (Siemreap) and one semi-urban (Kampong Cham). The diagnosis of diabetes and impaired glucose tolerance was based on 2-h blood glucose estimation using criteria recommended by the latest report of a WHO Expert Group. Blood pressure, anthropometry, habitual diet, and other relevant characteristics were also recorded. Prevalence of diabetes was 5% in Siemreap and 11% in Kampong Cham. Prevalence of impaired glucose tolerance was 10% in Siemreap and 15% in Kampong Cham. About two-thirds of all cases of diabetes were undiagnosed before the survey. Prevalence of hypertension was 12% at Siemreap and 25% at Kampong Cham. People in Kampong Cham had higher estimates of central obesity than those in Siemreap. Diabetes and hypertension are not uncommon in Cambodia. A quarter of all adults in the chosen suburban community had some degree of glucose intolerance. Since Cambodian society is relatively poor, and lifestyle is fairly traditional by international standards, these findings are unexpected.

    After catastrophic events in which people's survival has been threatened, as happened during the Khmer Rouge regime in Cambodia 1975-1979, some continue to suffer from painful mental symptoms. Surveys carried out in Cambodia based on Western diagnostic categories have found a high prevalence of posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in the population. This study explored Cambodian approaches to healing trauma, examining the ways in which Cambodians appeal to elements of Buddhism in their efforts to calm their minds, situating this mode of coping in the context of broader Khmer Buddhist practice and understandings. Western psychology may have much to learn from local, contextualised methods of dealing with the aftermath of trauma, including Khmer understandings of distress and approaches to relief. Methods of assessment and treatment of distress cannot be transposed wholesale from one cultural setting to another but require considerable cultural adaptation. This kind of cultural interchange may give rise to innovative, hybrid discourses and methods that may have much to offer in the support of victims of organised violence. © The Author(s) 2015.

    Full Text Available Although sustainability is of utmost importance, anecdotal evidence suggests that the concept is not adequately implemented in many developing countries. This paper investigates industry stakeholders’ awareness of the current state of, factors driving, and barriers hindering the adoption of sustainable construction (SC in Cambodia. Using an empirical questionnaire survey targeting local construction professionals, respondents were invited to rate their level of awareness, knowledge and understanding of SC, as well as to rate the level of importance of 31 drivers and 10 barriers identified from the seminal literature. The data set was subjected to the relative importance index method. The results suggest that the industry-wide adoption of SC practices is poor, which is believed to be due to a lack of awareness and knowledge, and reluctance to adopt new sustainable technologies. Furthermore, more efforts must be put into the selection of more durable materials for the extension of buildings’ lives and to minimize material consumption, as well as to develop energy-efficient buildings with minimal environmental impact and a healthy indoor environment, so that the ability of future generations to meet their own needs will not be compromised. The outcomes of this study have enriched knowledge about the current state of, drivers of, and barriers to sustainable construction in a typical developing economy. Although the outcomes of this study were a short scoping exercise, it has formed a significant base for future SC work within Cambodia.

    Full Text Available Abstract Background Dengue is endemic in Cambodia (pop. estimates 14.4 million, a country with poor health and economic indicators. Disease burden estimates help decision makers in setting priorities. Using recent estimates of dengue incidence in Cambodia, we estimated the cost of dengue and its burden using disability adjusted life years (DALYs. Methods Recent population-based cohort data were used to calculate direct and productive costs, and DALYs. Health seeking behaviors were taken into account in cost estimates. Specific age group incidence estimates were used in DALYs calculation. Results The mean cost per dengue case varied from US$36 - $75 over 2006-2008 respectively, resulting in an overall annual cost from US$3,327,284 in 2008 to US$14,429,513 during a large epidemic in 2007. Patients sustain the highest share of costs by paying an average of 78% of total costs and 63% of direct medical costs. DALY rates per 100,000 individuals ranged from 24.3 to 100.6 in 2007-2008 with 80% on average due to premature mortality. Conclusion Our analysis confirmed the high societal and individual family burden of dengue. Total costs represented between 0.03 and 0.17% of Gross Domestic Product. Health seeking behavior has a major impact on costs. The more accurate estimate used in this study will better allow decision makers to account for dengue costs particularly among the poor when balancing the benefits of introducing a potentially effective dengue vaccine.

    Human intestinal sarcocystosis (HIS), caused by Sarcocystis species, is acquired by eating undercooked meat from sarcocyst-containing cattle (S. hominis, S. heydorni) and pigs (S. suihominis). We report on the detection of human intestinal Sarcocystis infections in a cross-sectional survey of Strongyloides stercoralis in early 2014, in Rovieng District, Preah Vihear Province, northern Cambodia. Among 1081 participants, 108 (10.0%) were diagnosed with Sarcocystis spp. oocysts in stool samples. Males had a significantly higher risk of infection than females (OR: 1.9, 95% CI: 1.3-2.9, p=0.001). None of the reported symptoms (abdominal discomfort, diarrhea, muscle pain and itching skin) occurring in the two weeks preceding the examinations were associated with a Sarcocystis infection. Many Sarcocystis cases were found among those who had participated in a wedding celebration and Chinese New Year festivities, where they had consumed raw or insufficiently cooked beef (83.3%) and pork (38.9%) based dishes. This report documents the first HIS cases in Cambodia. Copyright © 2017 Elsevier B.V. All rights reserved.

    Prevalence of nontuberculous mycobacteria (NTM) disease is poorly documented in countries with high prevalence of tuberculosis (TB). We describe prevalence, risk factors, and TB program implications for NTM isolates and disease in Cambodia. A prospective cohort of 1,183 patients with presumptive TB underwent epidemiologic, clinical, radiologic, and microbiologic evaluation, including >12-months of follow-up for patients with NTM isolates. Prevalence of NTM isolates was 10.8% and of disease was 0.9%; 217 (18.3%) patients had TB. Of 197 smear-positive patients, 171 (86.8%) had TB confirmed (167 by culture and 4 by Xpert MTB/RIF assay only) and 11 (5.6%) had NTM isolates. HIV infection and past TB were independently associated with having NTM isolates. Improved detection of NTM isolates in Cambodia might require more systematic use of mycobacterial culture and the use of Xpert MTB/RIF to confirm smear-positive TB cases, especially in patients with HIV infection or a history of TB.

    Many survivors of the Khmer Rouge period in Cambodia and the subsequent war with Vietnam have now returned to Cambodia. In this two-stage household cluster survey in Siem Reap Province in Cambodia, we explored the mental health consequences on 166 landmine injury survivors selected from 1000 household in 50 clusters and an oversample of all landmine survivors. We found a prevalence of anxiety of 62% for all respondents, 74% for depression, and 34% for post-traumatic stress disorder (PTSD). These prevalences were statistically significantly higher than among the adult population who had not been injured by landmines. These data underscore the importance of providing mental health care services for the people in Siem Reap Province in Cambodia who have been injured by landmines.

    Ozone is an important pollutant and greenhouse gas, and tropospheric ozone variations are generally associated with both natural and anthropogenic processes. As one of the most pristine and inaccessible regions in the world, the Tibetan Plateau has been considered as an ideal region for studying processes of the background atmosphere. Due to the vast area of the Tibetan Plateau, sites in the southern, northern and central regions exhibit different patterns of variation in surface ozone. Here, we present continuous measurements of surface ozone mixing ratios at Nam Co Station over a period of ˜ 5 years (January 2011 to October 2015), which is a background site in the inland Tibetan Plateau. An average surface ozone mixing ratio of 47.6 ± 11.6 ppb (mean ± standard deviation) was recorded, and a large annual cycle was observed with maximum ozone mixing ratios in the spring and minimum ratios during the winter. The diurnal cycle is characterized by a minimum in the early morning and a maximum in the late afternoon. Nam Co Station represents a background region where surface ozone receives negligible local anthropogenic emissions inputs, and the anthropogenic contribution from South Asia in spring and China in summer may affect Nam Co Station occasionally. Surface ozone at Nam Co Station is mainly dominated by natural processes involving photochemical reactions, vertical mixing and downward transport of stratospheric air mass. Model results indicate that the study site is affected differently by the surrounding areas in different seasons: air masses from the southern Tibetan Plateau contribute to the high ozone levels in the spring, and enhanced ozone levels in the summer are associated with air masses from the northern Tibetan Plateau. By comparing measurements at Nam Co Station with those from other sites on the Tibetan Plateau, we aim to expand the understanding of ozone cycles and transport processes over the Tibetan Plateau. This work may provide a

    Full Text Available The aim of the study was to estimate the prevalence and psychosocial correlates of nonfatal injury among middle school students in Cambodia and Vietnam. Cross-sectional data from 7137 school children (mean age 15.5 years, SD = 1.4 who were randomly sampled for participation in nationally representative Global School-based Health Surveys (GSHS in Cambodia and Vietnam were analyzed. The proportion of school children reporting one or more serious injuries in the past year was 22.6% among boys and 17.5% among girls in Cambodia and 34.3% among boys and 25.1% among girls in Vietnam. The most prevalent cause of the most serious injury in Cambodia was traffic injuries (4.7% among boys and 4.3% among girls and in Vietnam it was falls (10.0% among boys and 7.0% among girls. In multinomial logistic regression analyses, experiencing hunger (as an indicator for low socioeconomic status and drug use were associated with having sustained one injury and two or more injuries in the past 12 months in Cambodia. In addition, poor mental health was associated with two or more injuries. In Vietnam, being male, experiencing hunger, current alcohol use, poor mental health and ever having had sex were associated with having sustained one injury and two or more injuries in the past 12 months. Several psychosocial variables were identified which could help in designing injury prevention strategies among middle school children in Cambodia and Vietnam.

    We describe an analysis of genome variation in 825 Plasmodium falciparum samples from Asia and Africa that reveals an unusual pattern of parasite population structure at the epicentre of artemisinin resistance in western Cambodia. Within this relatively small geographical area we have discovered several distinct but apparently sympatric parasite subpopulations with extremely high levels of genetic differentiation. Of particular interest are three subpopulations, all associated with clinical resistance to artemisinin, which have skewed allele frequency spectra and remarkably high levels of haplotype homozygosity, indicative of founder effects and recent population expansion. We provide a catalogue of SNPs that show high levels of differentiation in the artemisinin-resistant subpopulations, including codon variants in various transporter proteins and DNA mismatch repair proteins. These data provide a population genetic framework for investigating the biological origins of artemisinin resistance and for defining molecular markers to assist its elimination. PMID:23624527

    Epilepsy-related health outcomes remain unacceptably low in much of the developing world. According to us, it is because of the failure since long to see, and address, epilepsy beyond its preset conventional image. The objective of this paper was to highlight the presence, and influence, of these conventional practices and also to demonstrate what happened when a bold unconventional approach to address epilepsy was taken in Cambodia. Data are taken from existing published literature on epilepsy as well as our field experience during several population-based surveys conducted in Cambodia. We complimented this with our knowledge gained over this long period. It is demonstrated that epilepsy is far more important in Asia that it is currently considered to be, and also vis-à-vis other geographic regions. Pregnancy and birth-related factors carry far higher odds for epilepsy than several "highly vocal" infections. A refocus in epilepsy is required to help move from its traditional negative image to an image where epilepsy is considered a "positive-looking" disorder that is full of "opportunities;" such as availability of safe effective inexpensive treatment, etc. Stigma is a two-side entity (i.e., it is present, and it is influential), and diligence should be therefore practiced before using the stigma label. Nevertheless, psychosocial aspects shouldn't be limited to stigma or Jacoby stigma scale alone. Quality of life is a subjective phenomenon, and patients should determine directly what affects them. It is highly desirable that if we want to find newer answers to old problems in epilepsy, we need to shed our conventional approach and preset conclusions. We should choose to move toward "opportunities" visibly present in epilepsy. Our Cambodian experience demonstrates more intimately that opportunities do get identified when preset conclusions are questioned, and an approach that goes beyond expected and by default is taken.

    Pediatric bacterial bloodstream infections (BSIs) are a major cause of morbidity and mortality worldwide. Epidemiological data from resource-limited settings in southeast Asia, such as Cambodia, are sparse but have important implications for treatment and public health strategies. We retrospectively investigated BSI in children at a pediatric hospital and its satellite clinic in Siem Reap, Cambodia, from January 1, 2007, to July 31, 2011. The range of bacterial pathogens and their antimicrobial susceptibility patterns were analyzed in conjunction with demographic, clinical and outcome data. Of 7682 blood cultures with results (99.9% of cultures taken), 606 (7.9%) episodes of BSI were identified in 588 children. The incidence of BSI increased from 14 to 50/1000 admissions (P < 0.001); this was associated with an increased sampling rate. Most BSI were community acquired (89.1%). Common pathogens included Salmonella Typhi (22.8% of all isolates), Staphylococcus aureus (12.2%), Streptococcus pneumoniae (10.0%), Klebsiella pneumoniae (6.4%) and Escherichia coli (6.3%). 21.5% of BSI were caused by a diverse group of uncommon organisms, the majority of which were environmental Gram-negative species. No Listeria monocytogenes or Group B streptococcal BSI were identified. Antimicrobial resistance, particularly among the Enterobacteriaceae, was common. Overall mortality was substantial (19.0%), higher in neonates (36.9%) and independently associated with meningitis/meningoencephalitis and K. pneumoniae infection. BSI is a common problem in Cambodian children attending hospital and associated with significant mortality. Further studies are needed to clarify the epidemiology of neonatal sepsis, the contribution of atypical organisms and the epidemiology of pneumococcal disease before the introduction of vaccine.

    Vietnam's nursing competency standards (VNCS) were issued in 2012 as the legal framework on which the continuous nursing training programme are designed and developed. The study aimed to assess the knowledge, skills, and attitudes as well as the confidence of nurses regarding wound care at Viet Duc University Hospital before and after a new educational intervention. A comparative descriptive study was carried out in 2014 at Viet Duc University Hospital. The study reviewed knowledge, skills, attitude and confidence among nurses working in seven clinical departments. The data collection tools included a 48-knowledge-item self-administered questionnaire, a sixteen-item skills set, and attitude-item observation sheet and a thirteen confidence level-item observation sheet, adapted for the field of wound care. Data were loaded into Epidata version 3.1 and analysed with SPSS version 16.0. The mean pre-training knowledge, skill, attitude and confidence scores were (117.78±24.94), (53.61±10.26), (54.39±8.02) and (1.18-3.59), respectively, while the corresponding post-training scores were (148.68±16.54), (62.33±8.40), (60.80±8.75) and (1.50-4.15) p<0.0001. This was the first cohort to undergo the new training programme and has shown promising initial results; however, it also demonstrates that the training content, while leading to positive changes, does in some areas need to be further developed and then disseminated across the hospital to all nurses who provide direct wound care for patients.

    HIV-related stigma diminishes the quality of life of affected patients. Little is known about perceived and enacted stigma of HIV-infected children in resources-limited settings. We documented the prevalence of perceived stigma and associated factors associated among children on antiretroviral therapy (ART) at a referral hospital in Cambodia. After informed consent, a standardized pre-tested 47-item questionnaire was confidentially administered to consecutive children (7 to 15 years) or their guardians if the child was 18 months to 6 years, during their routine ART visits. The questionnaire explored the sociodemographics of the child and the parents, HIV history, adherence to ART, tolerance of ART and perceived stigma. Associations between perceived stigma and the children's characteristics were measured by bivariate and multivariate analyses. Of 183 children, 101 (55.2%) had lost at least one and 45 (24.6%) both parents; 166 (90.7%) went to school. Of 183 children (female: 84, 45.9%, median age 7.0 years, interquartile range: 2.0-9.6), 79 (43.2%) experienced perceived stigma, including rejection by others (26.8%), no invitations to social activities (18.6%) and exclusion from games (14.2%). A total of 43 (23.5%) children were fearful of their disease and 61 (53.9%) of 113 older than 6 years reported knowledge of their HIV status. Of 136 children over five years and eligible for education, 7 (3.8%) could not go to school due to perceived stigma. Incomplete adherence to ART was reported for 17 (9.2%) children. In multivariate analysis, school attendance (odds ratio [OR]: 3.9; 95% confidence interval [CI]: 2.0-7.9) and income of less than one dollar per person per day (OR: 2.2, 95% CI: 1.1-4.5) were associated with perceived stigma. Conversely, receipt of social support (OR: 0.4, 95% CI 0.2-0.9) was associated with lower risk of perceived stigma. Perceived stigma in pediatric ART patients remains a significant issue in Cambodia. Psychological support and

    Full Text Available Abstract Background Injection overuse and unsafe injection practices facilitate transmission of bloodborne pathogens such as hepatitis B virus (HBV, hepatitis C virus (HCV, and human immunodeficiency virus (HIV. Anecdotal reports of unsafe and unnecessary therapeutic injections and the high prevalence of HBV (8.0%, HCV (6.5%, and HIV (2.6% infection in Cambodia have raised concern over injection safety. To estimate the magnitude and patterns of such practices, a rapid assessment of injection practices was conducted. Methods We surveyed a random sample of the general population in Takeo Province and convenience samples of prescribers and injection providers in Takeo Province and Phnom Penh city regarding injection-related knowledge, attitudes, and practices. Injection providers were observed administering injections. Data were collected using standardized methods adapted from the World Health Organization safe injection assessment guidelines. Results Among the general population sample (n = 500, the overall injection rate was 5.9 injections per person-year, with 40% of participants reporting receipt of ≥ 1 injection during the previous 6 months. Therapeutic injections, intravenous infusions, and immunizations accounted for 74%, 16% and 10% of injections, respectively. The majority (>85% of injections were received in the private sector. All participants who recalled their last injection reported the injection was administered with a newly opened disposable syringe and needle. Prescribers (n = 60 reported that 47% of the total prescriptions they wrote included a therapeutic injection or infusion. Among injection providers (n = 60, 58% recapped the syringe after use and 13% did not dispose of the used needle and syringe appropriately. Over half (53% of the providers reported a needlestick injury during the previous 12 months. Ninety percent of prescribers and injection providers were aware HBV, HCV, and HIV were transmitted through unsafe

  20. Surface ozone at Nam Co in the inland Tibetan Plateau: variation, synthesis comparison and regional representativeness

    Full Text Available Ozone is an important pollutant and greenhouse gas, and tropospheric ozone variations are generally associated with both natural and anthropogenic processes. As one of the most pristine and inaccessible regions in the world, the Tibetan Plateau has been considered as an ideal region for studying processes of the background atmosphere. Due to the vast area of the Tibetan Plateau, sites in the southern, northern and central regions exhibit different patterns of variation in surface ozone. Here, we present continuous measurements of surface ozone mixing ratios at Nam Co Station over a period of  ∼ 5 years (January 2011 to October 2015, which is a background site in the inland Tibetan Plateau. An average surface ozone mixing ratio of 47.6 ± 11.6 ppb (mean ± standard deviation was recorded, and a large annual cycle was observed with maximum ozone mixing ratios in the spring and minimum ratios during the winter. The diurnal cycle is characterized by a minimum in the early morning and a maximum in the late afternoon. Nam Co Station represents a background region where surface ozone receives negligible local anthropogenic emissions inputs, and the anthropogenic contribution from South Asia in spring and China in summer may affect Nam Co Station occasionally. Surface ozone at Nam Co Station is mainly dominated by natural processes involving photochemical reactions, vertical mixing and downward transport of stratospheric air mass. Model results indicate that the study site is affected differently by the surrounding areas in different seasons: air masses from the southern Tibetan Plateau contribute to the high ozone levels in the spring, and enhanced ozone levels in the summer are associated with air masses from the northern Tibetan Plateau. By comparing measurements at Nam Co Station with those from other sites on the Tibetan Plateau, we aim to expand the understanding of ozone cycles and transport processes over the Tibetan Plateau

    Rapid testing for tetanus on serum or blood allows for an immediate evaluation of individual protection against tetanus in developed countries, using a "single step" immunochromatographic technique using tetanus toxoid. The specificity of these tests, compared to the reference method for tetanus, mouse serum neutralization testing, has however never been assessed in these countries, due to the difficulty to perform serum neutralization titration in mice, because of animal testing bioethical regulations. A collection of sera from adult volunteers in Cambodia, living in rural environment, was tested for tetanus antibodies by ELISA in France, and by mouse serum neutralization in Vietnam. This allowed estimating the sensitivity and specificity of 2 rapid tetanus tests, available on the market: TQS™ and Tetanotop™. The sensitivity of these tests was adequate, compared to mice serum neutralization test, for a test threshold of 0.01 IU/mL, (100% for TQS™, 91% for Tetanotop™), but their specificity was very low (1% for TQS™ and 13% for Tetanotop™). The results prove that these rapid tests for the assessment of individual protection against tetanus should not be used in the adult rural Cambodian population. Copyright © 2015 Elsevier Masson SAS.

    The in vitro antiplasmodial activity of 117 aqueous, methanol and dichloromethane extracts derived from different parts of 28 indigenous wild plant species was studied. These plants are commonly used in Cambodian traditional medicine. The plant extracts were tested for in vitro activity against a chloroquine resistant Plasmodium falciparum strain (W2). Nine extracts were moderately active with IC(50) values ranging between 5 and 10 microg/ml, 17 extracts were active with IC(50) values ranging between 1 and 5 microg/ml. These 26 extracts derived from eight plants belong to six families. The most active extracts were dichloromethane and came from Stephania rotunda and Brucea javanica with IC(50) values of 1 microg/ml and a selectivity index > or = 25. It is interesting to note that some aqueous extracts were as active as dichloromethane extracts especially aqueous extracts of Stephania rotunda, Brucea javanica, Phyllanthus urinaria and Eurycoma longifolia with IC(50) values of uses of these plants for the treatment of malaria and/or fever. In this study, we report the antiplasmodial potential activity of eight plant species from Cambodia. Among them four are tested for the first time.

    Mineral pot filters (MPFs) are household water treatment (HWT) devices that are manufactured and distributed by the private sector, with millions of users in Southeast Asia. Their effectiveness in reducing waterborne microbes has not been previously investigated. We purchased three types of MPFs available on the Cambodian market for systematic evaluation of bacteria, virus, and protozoan surrogate microbial reduction in laboratory challenge experiments following WHO recommended performance testing protocols. Results over the total 1500 L testing period per filter indicate that the devices tested were highly effective in reducing Esherichia coli (99.99%+), moderately effective in reducing bacteriophage MS2 (99%+), and somewhat effective against Bacillus atrophaeus, a spore-forming bacterium we used as a surrogate for protozoa (88%+). Treatment mechanisms for all filters included porous ceramic and activated carbon filtration. Our results suggest that these commercially available filters may be at least as effective against waterborne pathogens as other, locally available treatment options such as ceramic pot filters or boiling. More research is needed on the role these devices may play as interim solutions to the problem of unsafe drinking water in Cambodia and globally.

    The expanded programme of immunization was established in Cambodia in 1986. In 2002, 67% of eligible children were immunized, despite significant health sector and macro-economic financial constraints. A financial sustainability planning process for immunization was introduced in 2002, in order to mobilize national and international resources in support of the achievement of child health objectives. The aim of this paper is to outline this process, describe its early impact as an advocacy tool and recommend additional strategies for mobilizing additional resources for health. The methods of financial sustainability planning are described, including the advocacy strategies that were applied. Analysis of financial sustainability planning results indicates rising programme costs associated with new vaccine introduction and new technologies. Despite this, the national programme has demonstrated important early successes in using financial sustainability planning to advocate for increased mobilization of national and international sources of funding for immunization. The national immunization programme nevertheless faces formidable system and financial challenges in the coming years associated with rising costs, potentially diminishing sources of international assistance, and the developing role of sub-national authorities in programme management and financing.

    To assess the prevalence of counterfeit anthelminthic medicines in Cambodia, and to determine influential factors. Commonly used anthelminthic medicines were collected from private drug outlets. Medicines were carefully observed including their registration labelling, and their authenticity was investigated with the manufacturers and the Medicines Regulatory Authorities. Samples were analysed by High-Performance Liquid Chromatography at the National Health Product Quality Control Centre, Cambodia. Two hundred and three samples of anthelminthics were collected from 137 drug stores. Domestic products constituted 36.9%. Of 196 samples which were verified for registration, 15.8% were not registered. Of 165 samples successfully investigated for their authenticity, 7 (4.2%) were identified as counterfeit. All of these medicines were purchased in open packs or containers, and most of them were foreign manufactured and/or without registration. The results of our survey urge strict implementation of drug registration and vigilance on the availability of unregistered medicines to combat counterfeit medicines in Cambodia.

    To determine whether trachoma is a public health problem requiring intervention in Cambodia. Based on historical evidence and reports, 14 evaluation units (EUs) in Cambodia, judged to be most likely to harbor trachoma, were selected. The Global Trachoma Mapping Project methodology was used to carry out rigorous surveys to determine the prevalence of trachomatous inflammation-follicular (TF) and trichiasis in each EU. The EU-level prevalence of TF among 25,801 1-9-year-old children examined ranged from 0% to 0.2%. Among the 24,502 adults aged 15+ years examined, trichiasis was found in 59 people. Age- and sex-adjusted prevalences of trichiasis in all ages in the EUs studied ranged from 0% to 0.14%; five EUs had a prevalence of trichiasis ≥0.1%. There appears to be no need nor justification at this time for implementing public health measures to control trachoma in Cambodia.

    This case study illustrates a participatory framework for confronting critical community health issues using 'grass-roots' research-guided community-defined interventions. Ongoing work in Cambodia has culturally adapted research, theory and practice for particular, local health-promotion responses to HIV/AIDS, alcohol abuse and other challenges in the community of Siem Reap. For resource-poor communities in Cambodia, we recycle such 'older' concepts as 'empowerment' and 'action research'. We re-imagine community health psychology, when confronted with 'critical', life-and-death issues, as adjusting its research and practices to local, particular ontological and epistemological urgencies of trauma, morbidity and mortality.

    New hydrological insights: A water isotope framework for the Nam Co basin, including the Local Meteoric Water Line, limiting isotopic composition of evaporation and two hypothetical evaporation trajectories, is established. We further applied the isotope mass balance model to estimate the overall isotopic composition of input water to the Nam Co, the evaporation over inputs ratios (E/I for three consecutive years, and the water yields (Wy, depth equivalent runoff at a basin scale. Our results clearly suggest a positive water budget (i.e., E/I < 1, providing another line of evidence that the subsurface leakage from Nam Co is likely. The discrepancy between isotope-based water yields estimations and field-based runoff observations suggest that, compared to the well-studied Nyainqentanglha Mountains and southwestern mountains, the ridge-and-valley landscape in the western highlands and northwestern hogbacks are possibly low yields area, which should draw more research attentions in future hydrological investigations.

    A longer life brings opportunities for older adults and their families as well as for their communities. Commercial businesses can be successful in innovating on these opportunities and achieving business expansion when they better understand the market dynamics and spectrum of older adults as consumers and view them more as assets rather than as burdens to society. While there is no "typical" older adult consumer, some traits, characteristics, and physical realities may be more common, including those related to family and community, the shopping experience, brand marketing and packaging, food and nutrition, and health. The opportunities of longer life are impacted by health and underscore the importance of positive, healthy aging-related behaviors like good nutrition and active lifestyles. Healthy aging also requires a sustained commitment and action from country leaders to formulate evidence-based polices--like systematic nutrition screening and intervention-and healthcare workforce training and education that can strengthen and support an active aging population. In addition, governments should consider engaging commercial businesses to help set sustainable policies that can advance products for older adults. Finally, governments should set national and local goals to incentivize commercial business development and investment in public-private partnerships to improve quality of care, promote healthy aging, and impact outcomes for noncommunicable diseases, ultimately benefitting population health for Asia-Pacific Economic Cooperation (APEC) countries.

  10. Observation des influences du changement du couvert forestier sur le comportement hydrologique de grands bassins versants tropicaux a l'aide de la teledetection numerique: Cas du bassin versant de Dong Nai, Viet Nam

    Pham, Trinh Hung

    Monitoring hydrological behavior of a large tropical watershed following a forest cover variation has an important role in water resource management planning as well as for forest sustainable management. Traditional methods in forest hydrology studies are Experimental watersheds, Upstream-downstream, Experimental plots, Statistical regional analysis and Watershed simulation. Those methodes have limitations for large watersheds concerning the monitoring time, the lack of input data especially about forest cover and the capacity of extrapolating results accurately in terms of large watersheds. Moreover, there is still currently a scientific debate in forest ecology on relation between water and forest. The reason of this problem comes from geographical differences in publication concerning study zones, experimental watershed size and applied methods. It gives differences in the conclusions on the influence of tropical forest cover change on the changes of outlet water and yet on the yearly runoff in terms of large watershed. In order to exceed the limitations of actual methods, to solve the difficulty of acquiring forest cover data and to have a better understanding of the relation between tropical forest cover change and hydrological behavior evolution of a large watershed, it is necessary to develop a new approach by using numeric remote sensing. We used the watershed of Dong Nai as a case study. Results show that a fusion between TM and ETM+ Landsat image series and hydro-meteorologic data allow us to observe and detect flooding trends and flooding peaks after an intensive forest cover change from 16% to 20%. Flooding frequency and flooding peaks have clearly decreased when there is an increase of the forest cover from 1983 to 1990. The influence of tropical forest cover on the hydrological behavior is varying with geographical locations of watershed. There is a significant relation between forest cover evolution and environmental facteurs as the runoff coefficient (R = 0,87) and the yearly precipitation (R = 0,93).

    In Cambodia, the first detection of HPAI H5N1 virus in birds occurred in January 2004 and since then there have been 33 outbreaks in poultry while 21 human cases were reported. The origin and dynamics of these epizootics in Cambodia remain unclear. In this work we used a range of bioinformatics methods to analyze the Cambodian virus sequences together with those from neighboring countries. Six HA lineages belonging to clades 1 and 1.1 were identified since 2004. Lineage 1 shares an ancestor with viruses from Thailand and disappeared after 2005, to be replaced by lineage 2 originating from Vietnam and then by lineage 3. The highly adapted lineage 4 was seen only in Cambodia. Lineage 5 is circulating both in Vietnam and Cambodia since 2008 and was probably introduced in Cambodia through unregistered transboundary poultry trade. Lineage 6 is endemic to Cambodia since 2010 and could be classified as a new clade according to WHO/OIE/FAO criteria for H5N1 virus nomenclature. We propose to name it clade 1.1A. There is a direct filiation of lineages 2 to 6 with a temporal evolution and geographic differentiation for lineages 4 and 6. By the end of 2011, two lineages, i.e. lineages 5 and 6, with different transmission paths cocirculate in Cambodia. The presence of lineage 6 only in Cambodia suggests the existence of a transmission specific to this country whereas the presence of lineage 5 in both Cambodia and Vietnam indicates a distinct way of circulation of infected poultry.

The selected four isolates inhibit the growth of fungal nycelia by 47.01-50.00 % including YFm1, YFm2, Y18 and AC2-1 were test for the potential reduce anthracnose lesion development on detected Nam Dok Mai mango by application of antagonistic microorganism before inoculation of C. gloeosporioides. This result slow that four isolate antagonistic reduced sized of lesion on Nam Dok Mai mango by 89.23, 75.38, 58.46 and 33.85 %, respectively as compare the control. Five isolate of antagonist including YFm1, YFm2, Y18, CLY35 and CLY23 could inhibited the growth of mycelia on PDA by 44.01-50.00 % were test the potential reduce anthracnose lesion development on detected Nam Dok Mai mango by application of antagonistic microorganism after inoculation of C. gloeosporioides. It was found that this application could not inhibit anthracnose on fruit mango as compare to the control. YFm1 were test for the potential inhibition anthracnose disease under field condition. It was found that YFm1 could control of C. gloeosporioides within 7 and 14 day after spraying antagonistic suspension. The efficiency test of YFm1 for anthracnose controlling on mango was followed by export treatment Azoxystrobin, ET-fon and showed 55.55%, 77.77 % and 88.88 % anthracnose infection and/or spoilage respectively

    Previous studies have shown that the majority of the lakes in the Tibetan Plateau (TP) started to expand rapidly since the late 1990s. However, the causes are still not well known. For Nam Co, being a closed lake with no outflow, evaporation (EL) over the lake surface is the only way water may leave the lake. Therefore, quantifying EL is key for investigating the mechanism of lake expansion in the TP. EL can be quantified by Penman- and/or bulk-transfer-type models, requiring only net radiation, temperature, humidity and wind speed for inputs. However, interpolation of wind speed data may be laden with great uncertainty due to extremely sparse ground meteorological observations, the highly heterogeneous landscape and lake-land breeze effects. Here, evaporation of Nam Co Lake was investigated within the 1979-2012 period at a monthly time-scale using the complementary relationship lake evaporation (CRLE) model which does not require wind speed data. Validations by in-situ observations of E601B pan evaporation rates at the shore of Nam Co Lake as well as measured EL over an adjacent small lake using eddy covariance technique suggest that CRLE is capable of simulating EL well since it implicitly considers wind effects on evaporation via its vapor transfer coefficient. The multi-year average of annual evaporation of Nam Co Lake is 635 mm. From 1979 to 2012, annual evaporation of Nam Co Lake expressed a very slight decreasing trend. However, a more significant decrease in EL occurred during 1998-2008 at a rate of -12 mm yr-1. Based on water-level readings, this significant decrease in lake evaporation was found to be responsible for approximately 4% of the reported rapid water level increase and areal expansion of Nam Co Lake during the same period.

    The prevalence of micronutrient deficiencies in Cambodia is among the highest in Southeast Asia. Fortification of staple foods and condiments is considered to be one of the most cost-effective strategies for addressing micronutrient deficiencies at the population level. The Government of Cambodia has recognized the importance of food fortification as one strategy for improving the nutrition security of its population. This paper describes efforts under way in Cambodia for the fortification of fish sauce, soy sauce, and vegetable oil. Data were compiled from a stability test of Cambodian fish sauces fortified with sodium iron ethylenediaminetetraacetate (NaFeEDTA); analysis of fortified vegetable oils in the Cambodian market; a Knowledge, Attitudes, and Practices (KAP) study of fortified products; and food fortification program monitoring documents. At different levels of fortification of fish sauce with NaFeEDTA, sedimentation and precipitation were observed. This was taken into consideration in the government-issued standards for the fortification of fish sauce. All major brands of vegetable oil found in markets at the village and provincial levels are imported, and most are nonfortified. Fish sauce, soy sauce, and vegetable oil are widely consumed throughout Cambodia and are readily available in provincial and village markets. Together with an effective regulatory monitoring system, the government can guarantee that these commodities, whether locally produced or imported, are adequately fortified. A communications campaign would be worthwhile, once fortified commodities are available, as the KAP study found that Cambodians had a positive perception of fortified sauces.

    Cambodia is among the 28 worst countries globally with the highest rates of childhood malnutrition. The aim of the assessment was to apply published evidence associating malnutrition and a variety of functional consequences to project economic implications of this high rate of childhood malnutrition. Such information is vital to advocate for appropriate programs and action plan to reduce malnutrition (from severe stunting to micronutrient deficiencies). This exercise used a "consequence model" to apply these "coefficients of loss" established in the global scientific literature to Cambodia health, demographic and economic data to develop a national estimation of the economic losses link to malnutrition. The impact of the indicators of malnutrition analysed represent a burden to the national economy of Cambodia estimated at more than $400 million annually -2.5% of GDP. Micronutrient deficiencies suggest deficits in the quality of the diet - representing a national burden of more than $200 million annually while breastfeeding behaviours account for 6% of the burden. 57% of the losses emerge from indicators measured in children, while 43% of losses are from indicators independent of childhood measurements - indicators of maternal behaviour along with maternal and adult nutrition. Given the low cost of interventions and the high baseline losses, investment in nutrition programs in Cambodia is likely to offer high returns and attractive benefit cost ratios. Since nearly half the losses are determined prior to the birth of the child, this has implications for targeting and timing of programs.

    2012-09-01

    Full Text Available Cambodia’s recent history of instability has garnered it international notoriety as a place of genocide, corruption and insecurity. Currently, this perception of Cambodia has resulted in an influx of tourists seeking to volunteer at and visit orphanages throughout the country hoping to combat the perceived poverty and suffering. With only 21 state-run orphanages in Cambodia the remaining 248 (although it is potentially even more rely significantly on over-seas donations with many advertising and heavily encouraging ‘orphanage tourism’. Although touted as an altruistic, beneficial experience, awareness of the darker side of ‘orphanage tourism’ has recently grown and the negative impacts that such practices can have on a vulnerable section of society have become evident. Orphan numbers in Cambodia are at their lowest point in decades, whilst orphanage numbers have undergone a 76 per cent increase in the last five years, coinciding with a 76 per cent increase in tourist numbers. This research investigates the forms that ‘orphanage tourism’ takes in Cambodia and the impacts of this popular phenomenon on those who are purported to benefit: orphanages and orphans.

    Soil-transmitted helminth (STH) infections and zinc deficiency are often found in low- and middle-income countries and are both known to affect child growth. However, studies combining data on zinc and STH are lacking. In two studies in schoolchildren in Cuba and Cambodia, we collected data on height, STH infection and zinc concentration in either plasma (Cambodia) or hair (Cuba). We analyzed whether STH and/or zinc were associated with height for age z-scores and whether STH and zinc were associated. In Cuba, STH prevalence was 8.4%; these were mainly Ascaris lumbricoides and Trichuris trichiura infections. In Cambodia, STH prevalence was 16.8%, mostly caused by hookworm. In Cuban children, STH infection had a strong association with height for age (aB-0.438, p = 0.001), while hair zinc was significantly associated with height for age only in STH uninfected children. In Cambodian children, plasma zinc was associated with height for age (aB-0.033, p = 0.029), but STH infection was not. Only in Cambodia, STH infection showed an association with zinc concentration (aB-0.233, p = 0.051). Factors influencing child growth differ between populations and may depend on prevalences of STH species and zinc deficiency. Further research is needed to elucidate these relationships and their underlying mechanisms.

    Authorities have pledged to eliminate canine rabies by 2020 in Cambodia, a country with a very high rabies burden. Logistic and financial access to timely and adequate postexposure prophylaxis (PEP) is essential for preventing rabies in humans. We undertook a survey of the few identified sites where PEP rabies vaccination and rabies immunoglobulin (RIG) are available in Cambodia. We examined the Rabies Prevention Center at Institut Pasteur du Cambodge (rpc@ipc) database and rpc@ipc order forms for 2012 to assess vaccine and RIG use. We conducted a rapid internet survey of centers that provide rabies vaccine and RIG in Cambodia, other than rpc@ipc. The cost of a full course of intramuscular or intradermal PEP in Cambodia, with and without RIG, was also estimated. Rabies vaccination is free of charge in one foundation hospital and is accessible for a fee at Institut Pasteur du Cambodge (IPC), some institutions, and some Cambodian private clinics. In 2012, 27,500 rabies vaccine doses (0.5 mL) and 591 equine RIG doses were used to provide intradermal PEP to 20,610 persons at rpc@ipc following animal bites. Outside of rpc@ipc, an estimated total of 53,400 vaccine doses and 200 RIG doses were used in Cambodia in 2012. The wholesale cost of full rabies PEP was estimated at 50% to 100% of a Cambodian farmer's monthly wage. Local populations and travelers cannot be sure to locally access adequate and timely PEP due to high costs and low access to RIG. Travelers to high-endemic areas such as Cambodia are strongly encouraged to undergo pre-exposure vaccination or seek expert advice, as per World Health Organization (WHO) recommendations. State-subsidized, pre-positioned stocks of human vaccine and RIG in bite management centers would extend the rabies prevention centers network. Support from Institut Pasteur du Cambodge for staff training, cold chain, and quality control would contribute to reducing the risk of rabies deaths in Cambodia. © 2015 International Society of

    2009-10-01

    Cambodia, following decades of civil conflict and social and economic transition, has in the last 10 years developed health policy innovations in the areas of health contracting, health financing and health planning. This paper aims to outline recent social, epidemiological and demographic health trends in Cambodia, and on the basis of this outline, to analyse and discuss these policy responses to social transition. Sources of information included a literature review, participant observation in health planning development in Cambodia between 1993 and 2008, and comparative analysis of demographic health surveys between 2000 and 2005. In Cambodia there have been sharp but unequal improvements in child mortality, and persisting high maternal mortality rates. Data analysis demonstrates associations between location, education level and access to facility based care, suggesting the dominant role of socio-economic factors in determining access to facility based health care. These events are taking place against a background of rapid social transition in Cambodian history, including processes of decentralization, privatization and the development of open market economic systems. Primary policy responses of the Ministry of Health to social transition and associated health inequities include the establishment of health contracting, hospital health equity funds and public-private collaborations. Despite the internationally recognized health policy flexibility and innovation demonstrated in Cambodia, policy response still lags well behind the reality of social transition. In order to minimize the delay between transition and response, new policy making tactics are required in order to provide more flexible and timely responses to the ongoing social transition and its impacts on population health needs in the lowest socio-economic quintiles.

    Full Text Available DOI:10.17014/ijog.3.2.127-137The Nam Con Son Basin covering an area of circa 110,000 km2 is characterized by complex tectonic settings of the basin which has not fully been understood. Multiple faults allowed favourable migration passageways for hydrocarbons to go in and out of traps. Despite a large amount of newly acquired seismic and well data there is no significant update on the tectonic evolution and history of the basin development. In this study, the vast amount of seismic and well data were integrated and reinterpreted to define the key structural events in the Nam Con Son Basin. The results show that the basin has undergone two extentional phases. The first N - S extensional phase terminated at around 30 M.a. forming E - W trending grabens which are complicated by multiple half grabens filled by Lower Oligocene sediments. These grabens were reactivated during the second NW - SE extension (Middle Miocene, that resulted from the progressive propagation of NE-SW listric fault from the middle part of the grabens to the margins, and the large scale building up of roll-over structure. Further to the SW, the faults of the second extentional phase turn to NNE-SSW and ultimately N - S in the SW edge of the basin. Most of the fault systems were inactive by Upper Miocene except for the N - S fault system which is still active until recent time.

From the joint field surveys between Korean and Laos experts conducted during 2015–2017, it was found that there are 64 families, 145 genera, and 189 species distributed in the Nam Ba National Biodiversity Conservation Area, and a total of 56 families, 117 genera, and 148 species which comprise more than 78% of the total species were identified as endemic plants to the Lao People's Democratic Republic. Considering the usage of the plants, there are 91 species of medicinal plants, 33 species of ornamental plants, eight species of edible plants, and 16 species of economic plants. In addition, it was found out that Dalbergia balansae and Cinnamomum macrocarpum are categorized as vulnerable in the International Union for Conservation of Nature (IUCN Red list, and 13 more species are categorized as the least concern.

    This image of Cambodia's Angkor region, taken by NASA's Airborne Synthetic Aperture Radar (AIRSAR), reveals a temple (upper-right) not depicted on early 19th Century French archeological survey maps and American topographic maps. The temple, known as 'Sman Teng,' was known to the local Khmer people, but had remained unknown to historians due to the remoteness of its location. The temple is thought to date to the 11th Century: the heyday of Angkor. It is an important indicator of the strategic and natural resource contributions of the area northwest of the capitol, to the urban center of Angkor. Sman Teng, the name designating one of the many types of rice enjoyed by the Khmer, was 'discovered' by a scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif., working in collaboration with an archaeological expert on the Angkor region. Analysis of this remote area was a true collaboration of archaeology and technology. Locating the temple of Sman Teng required the skills of scientists trained to spot the types of topographic anomalies that only radar can reveal.This image, with a pixel spacing of 5 meters (16.4 feet), depicts an area of approximately 5 by 4.7 kilometers (3.1 by 2.9 miles). North is at top. Image brightness is from the P-band (68 centimeters, or 26.8 inches) wavelength radar backscatter, a measure of how much energy the surface reflects back toward the radar. Color is used to represent elevation contours. One cycle of color represents 25 meters (82 feet) of elevation change, so going from blue to red to yellow to green and back to blue again corresponds to 25 meters (82 feet) of elevation change.AIRSAR flies aboard a NASA DC-8 based at NASA's Dryden Flight Research Center, Edwards, Calif. In the TOPSAR mode, AIRSAR collects radar interferometry data from two spatially separated antennas (2.6 meters, or 8.5 feet). Information from the two antennas is used to form radar backscatter imagery and to generate highly accurate elevation data. Built

    Full Text Available Given the opportunities offered by foreign investment in energy infrastructure mostly by Chinese firms, the Government of Cambodia is giving high priority to developing hydropower resources for reducing energy poverty and powering economic growth. Using a “Political ecology of the Asian drivers” framework, this paper assesses China’s involvement in the development of large dams’ in Cambodia and its impacts on the access of natural resources such as water and energy by dam builders, local communities and the government. This analysis is based on 61 interviews and 10 focus group discussions with affected communities, institutional actors, Chinese dam builders and financiers in relation to the first large Chinese dam built in Cambodia: the Kamchay dam. Based on the results of the analysis this paper makes recommendations on how to improve the planning, implementation and governance of future large dams in Cambodia.

    Cambodia faces major challenges in its effort to provide access to health care for all. Although there is a sharp improvement in health and health care in Cambodia, 6 in 10 women still deliver at home assisted by unskilled birth attendants. This practice is associated with higher maternal and infant deaths. This article analyzes the 2005 Cambodia Demographic and Health Survey data to examine the relationship between socioeconomic inequality and deliveries at home assisted by unskilled birth attendants. It is evident that babies in poorer households are significantly more likely to be delivered at home by an unskilled birth attendant than those in wealthier households. Moreover, delivery at home by an unskilled attendant is associated with mothers who have no education, live in a rural residence, and are farmers, and with higher birth order children. Results from this analysis demonstrate that socioeconomic inequality is still a major factor contributing to ill health in Cambodia. © 2011 APJPH.

Here, we study the effects of logging, mortality and recruitment of plot trees on phylogenetic community structure in 32 plots in Kampong Thom, Cambodia. Each plot was 0.25 ha; 28 plots were established in primary evergreen forests and four were established in se...

    Nam, Jost, and van Bavel (2013) found that conservatives were more likely than liberals to avoid dissonance-arousing situations (viz., writing counter-attitudinal essays in a high-choice situation). A close replication of this original research was unsuccessful, as both liberals and conservatives

    Full Text Available Cambodia is prone to extreme weather events, especially floods, droughts and typhoons. Climate change is predicted to increase the frequency and intensity of such events. The Cambodian population is highly vulnerable to the impacts of these events due to poverty; malnutrition; agricultural dependence; settlements in flood-prone areas, and public health, governance and technological limitations. Yet little is known about the health impacts of extreme weather events in Cambodia. Given the extremely low adaptive capacity of the population, this is a crucial knowledge gap. A literature review of the health impacts of floods, droughts and typhoons in Cambodia was conducted, with regional and global information reviewed where Cambodia-specific literature was lacking. Water-borne diseases are of particular concern in Cambodia, in the face of extreme weather events and climate change, due to, inter alia, a high pre-existing burden of diseases such as diarrhoeal illness and a lack of improved sanitation infrastructure in rural areas. A time-series analysis under quasi-Poisson distribution was used to evaluate the association between floods and diarrhoeal disease incidence in Cambodian children between 2001 and 2012 in 16 Cambodian provinces. Floods were significantly associated with increased diarrhoeal disease in two provinces, while the analysis conducted suggested a possible protective effect from toilets and piped water. Addressing the specific, local pre-existing vulnerabilities is vital to promoting population health resilience and strengthening adaptive capacity to extreme weather events and climate change in Cambodia.

    Artemisinin-resistant Plasmodium falciparum malaria has recently been identified on the Thailand-Cambodia border and more recently in parts of Thailand, Myanmar and Vietnam. There is concern that if this resistance were to spread, it would severely hamper malaria control and elimination efforts worldwide. Efforts are currently underway to intensify malaria control activities and ultimately eliminate malaria from Cambodia. To support these efforts, it is crucial to have a detailed picture of disease burden and its major determinants over time. An analysis of spatial and temporal data on clinical malaria in Cambodia collected by the National Centre for Parasitology, Entomology and Malaria Control (CNM) and the Department of Planning and Health Information, Ministry of Health Cambodia from 2004 to 2013 is presented. There has been a marked decrease of 81% in annual cases due to P. falciparum since 2009 coinciding with a rapid scale-up in village malaria workers (VMWs) and insecticide-treated bed nets (ITNs). Concurrently, the number of cases with Plasmodium vivax has greatly increased. It is estimated that there were around 112,000 total cases in 2012, 2.8 times greater than the WHO estimate for that year, and 68,000 in 2013 (an annual parasite incidence (API) of 4.6/1000). With the scale-up of VMWs, numbers of patients presenting to government facilities did not fall and it appears likely that those who saw VMWs had previously accessed healthcare in the private sector. Malaria mortality has decreased, particularly in areas with VMWs. There has been a marked decrease in cases in parts of western Cambodia, especially in Pailin and Battambang Provinces. In the northeast, the fall in malaria burden has been more modest, this area having the highest API in 2013. The clinical burden of falciparum malaria in most areas of Cambodia has greatly decreased from 2009 to 2013, associated with roll-out of ITNs and VMWs. Numbers of cases with P. vivax have increased.

    Full Text Available Vietnam is highly vulnerable to flood and storm impacts. Holistic flood risk assessment maps that adequately consider flood risk factors of hazard, exposure, and vulnerability are not available. These are vital for flood risk preparedness and disaster mitigation measures at the local scale. Unfortunately, there is a lack of knowledge about spatial multicriteria decision analysis and flood risk analysis more broadly in Vietnam. In response to this need, we identify and quantify flood risk components in Quang Nam province through spatial multicriteria decision analysis. The study presents a new approach to local flood risk assessment mapping, which combines historical flood marks with exposure and vulnerability data. The flood risk map output could assist and empower decision-makers in undertaking flood risk management activities in the province. Our study demonstrates a methodology to build flood risk assessment maps using flood mark, exposure and vulnerability data, which could be applied in other provinces in Vietnam.

    Dengue fever continues to be a major public health problem in Cambodia, with significant impact on children. Health education is a major means for prevention and control of the National Dengue Control Program (NDCP), and is delivered to communities and in schools. Drawing on data collected in 2003-2004 as part of an ethnographic study conducted in eastern Cambodia, we explore the approaches used in health education and their effectiveness to control dengue. Community health education is provided through health centre outreach activities and campaigns of the NDCP, but is not systematically evaluated, is under-funded and delivered irregularly; school-based education is restricted in terms of time and lacks follow-up in terms of practical activities for prevention and control. As a result, adherence is partial. We suggest the need for sustained routine education for dengue prevention and control, and the need for approaches to ensure the translation of knowledge into practice.

    Climate change imposes some special risks on Least Developed Countries, and the chapter presents a methodological framework, which can be used to assess the impacts of key assumptions related to damage costs, risks and equity implications on current and future generations. The methodological...... framework is applied to a case study of severe storms in Cambodia based on statistical information on past storm events including information about buildings damaged and victims. Despite there is limited data available on the probability of severe storm events under climate change as well on the actual...... damage costs associated with the events in the case of Cambodia, we are using the past storm events as proxy data in a sensitivity analysis. It is here demonstrated how key assumptions on future climate change, income levels of victims, and income distribution over time, reflected in discount rates...

    Equivalent black carbon (eBC) mass concentrations were measured by an aethalometer (AE-31) in the Nam Co, central Tibet from 2010 to 2014. Different from previous filter-sampling studies (Ming et al., J Environ Sci 22(11):1748-1756, 2010; Zhao et al., Environ Sci Pollut Res 20:5827-5838, 2013), the first high-resolution online eBC measurement conducted in central Tibet is reported here, allowing to discuss the diurnal variations as well as seasonal variabilities of eBC. Average daily eBC concentration was 74 ± 50 ng/m 3 , reflecting a global background level. Meteorological conditions influenced eBC concentrations largely at seasonal scale, which are higher in February-May but lower in June-January. The highest eBC concentrations (greater than 210 ng/m 3 ) were more associated with the W and WSW winds smaller than 6 m/s. The diurnal variations of eBC showed plateaus from 10:00 to 15:00 with seasonal variations, associated with local anthropogenic activities, such as indigenous Tibetan burning animal waste and tourism traffic. The PBLHs showed a co-variance with eBC concentrations, implicating close sources. The aerosol optical depths derived from the MODIS data over the Nam Co Observatory Station (NCOS)-included sub-area (30° N-40° N, 90° E-100° E) showed significant relationship with eBC concentrations. This suggests that nearby or short-distance sources other than long-distance transported pollutants could be important contributors to eBC concentrations at the NCOS, different from the conclusions suggested by previous studies.

    To measure trends in the pulmonary tuberculosis burden between 2002 and 2011 and to assess the impact of the DOTS (directly observed treatment, short-course) strategy in Cambodia. Cambodia's first population-based nationwide tuberculosis survey, based on multistage cluster sampling, was conducted in 2002. The second tuberculosis survey, encompassing 62 clusters, followed in 2011. Participants aged 15 years or older were screened for active pulmonary tuberculosis with chest radiography and/or for tuberculosis symptoms. For diagnostic confirmation, sputum smear and culture were conducted on those whose screening results were positive. Of the 40,423 eligible subjects, 37,417 (92.6%) participated in the survey; 103 smear-positive cases and 211 smear-negative, culture-positive cases were identified. The weighted prevalences of smear-positive tuberculosis and bacteriologically-positive tuberculosis were 271 (95% confidence interval, CI: 212-348) and 831 (95% CI: 707-977) per 100,000 population, respectively. Tuberculosis prevalence was higher in men than women and increased with age. A 38% decline in smear-positive tuberculosis (P = 0.0085) was observed with respect to the 2002 survey, after participants were matched by demographic and geographical characteristics. The prevalence of symptomatic, smear-positive tuberculosis decreased by 56% (P = 0.001), whereas the prevalence of asymptomatic, smear-positive tuberculosis decreased by only 7% (P = 0.7249). The tuberculosis burden in Cambodia has declined significantly, most probably because of the decentralization of DOTS to health centres. To further reduce the tuberculosis burden in Cambodia, tuberculosis control should be strengthened and should focus on identifying cases without symptoms and in the middle-aged and elderly population.

    This study examined the impact of parental styles on second generation effects of trauma among adolescent offspring of survivors of the Khmer Rouge (KR) genocide in Cambodia. Two hundred high school students completed measures addressing their parents' trauma stemming from the KR regime, parental styles (role reversing, overprotective), depression and anxiety. Parents' role reversing parental style and mothers' overprotective parenting were shown to mediate the impact of their trauma symptoms on the child's depression and anxiety. The implications of the findings are discussed.

    Rapid urbanization and motorization without corresponding increases in helmet usage have made traumatic brain injury due to road traffic accidents a major public health crisis in Cambodia. This analysis was conducted to quantify the impact of helmets on severity of injury, neurosurgical indication, and functional outcomes at discharge for motorcycle operators who required hospitalization for a traumatic brain injury following a road traffic accident in Cambodia. The medical records of 491 motorcycle operators who presented to a major tertiary care center in Cambodia with traumatic brain injury were retrospectively analyzed using multivariate logistic regression. The most common injuries at presentation were contusions (47.0%), epidural hematomas (30.1%), subdural hematomas (27.9%), subarachnoid hemorrhages (12.4%), skull fractures (21.4%), and facial fractures (18.5%). Moderate-to-severe loss of consciousness was present in 36.3% of patients. Not wearing a helmet was associated with an odds ratio of 2.20 (95% confidence interval [CI], 1.15-4.22) for presenting with moderate to severe loss of consciousness compared to helmeted patients. Craniotomy or craniectomy was indicated for evacuation of hematoma in 20.0% of cases, and nonhelmeted patients had 3.21-fold higher odds of requiring neurosurgical intervention (95% CI, 1.25-8.27). Furthermore, lack of helmet usage was associated with 2.72-fold higher odds of discharge with functional deficits (95% CI, 1.14-6.49). In total, 30.1% of patients were discharged with severe functional deficits. Helmets demonstrate a protective effect and may be an effective public health intervention to significantly reduce the burden of traumatic brain injury in Cambodia and other developing countries with increasing rates of motorization across the world.

    Phthalate esters are used in a wide variety of consumer products, and human exposure to this class of compounds is widespread. Nevertheless, studies on dietary exposure of human to phthalates are limited. In this study, to assess the daily intakes of phthalate esters and the possible adverse health impacts, different food samples were collected from three areas of Cambodia, one of the poorest countries in the world. The ∑phthalate ester concentrations in Kampong Cham, Kratie and Kandal provinces ranged from 0.05 to 2.34 (median 0.88) μg g −1 , 0.19–1.65 (median 0.86) μg g −1 and 0.24–3.05 (median 0.59) μg g −1 wet weight (ww), respectively. Di-2-Ethylhexyl phthalate (DEHP) and diisobutyl phthalate (DiBP) were the predominant compounds among all foodstuffs. The estimated daily intake (EDI) of phthalate esters for the general population in Kampong Cham, Kratie and Kandal was 34.3, 35.6 and 35.8 μg kg −1 bw d −1 , respectively. The dietary daily intake of DEHP, benzylbutyl phthalate (BBP) and di-n-butyl phthalate (DBP) in Kampong Cham, Kratie and Kandal were below the tolerable daily intakes (TDI) imposed by the European Food Safety Authority (EFSA) and reference doses (RfD) imposed by The United States Environmental Protection Agency (USEPA). Rice contributed the greatest quantity of DEHP to the daily intake in Cambodia so may deserve further exploration. To our knowledge, this is the first study to investigate the occurrence and the daily intakes of phthalate esters in Cambodia. - Highlights: • Phthalate esters concentration in daily foodstuffs collected from Cambodia. • Investigate the bioaccessbility of phthalate esters via the foodstuffs consumption. • Health risk evaluation of dietary exposure to phthalate esters.
