    1993-01-01

    Between 1991 and 1993 in Cambodia, the number of blood donors who tested seropositive for HIV multiplied by 10. During March-December 1993, 30 of 4000 (0.75%) blood donors were HIV positive. These same 30 were among 91 HIV-positive cases reported to the World Health Organization [WHO] office in Phnom Penh in the last 9 months of 1992. As Cambodia attempts to recover from many years of political and social upheaval, the recent repatriation of 370,000 Khmer refugees from Thailand intensifies the increasing AIDS threat. Thailand already has a relatively high HIV prevalence. The number of tourists and visiting business professionals is increasing, and 22,000 people from the UN Transitional Authority in Cambodia have been assigned to positions countrywide. In 1991, WHO officials designed a 1-year short-term AIDS prevention program aimed at people practicing high-risk behavior and the health, education, and media sectors. It targeted mainly Phnom Penh residents, WHO and the UN Development Programme (UNDP) are helping the National AIDS Committee in designing a more comprehensive national plan. UNDP plans to give US$ 1 million to AIDS prevention efforts in Cambodia. 20-30% of people in Cambodia are not familiar with condoms. Government AIDS prevention efforts are intended for the general public, but they also are going to target high-risk areas, especially the provinces bordering Thailand and the pot of Kompong Som. The government is working on ways to work with the many health-centered nongovernmental organizations in Cambodia. Even though it is inundated with many other problems, the government recognizes the need to combat AIDS.

    Many fires (red pixels) were seen burning across Thailand and Southern Cambodia on January 8, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Terra satellite. Almost the entire countries of Thailand (center) and Cambodia (lower right) were remarkably cloud-free in this true-color scene. Thailand is bordered by the countries of Myanmar to the west, Laos to the north and east, and Cambodia to the southeast. Thailand's capital city of Bangkok sits on its southern shore, where the Chao Phraya River flows into the large bay in the northern Gulf of Thailand. Moving eastward from Bangkok, one can see the Tonle Sap-Cambodia's largest inland body of water. Waters from the Tonle Sap flow southeastward and converge with the mighty Mekong River, just east of Phnom Penh, Cambodia's capital. The Mekong River defines much of the border between Thailand and Laos. The captal of Laos-Viangchan-is situated just across the Mekong from Thailand's northern border.

    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.

    Dual sensor is one of the most promising sensors for humanitarian demining operations. Conventional landmine detection depends on highly trained and focused human operators manually sweeping 1m2 plots with a metal detector and listening for characteristic audio signals indicating the presence of AP (Anti-personnel) landmines. In order to reduce the time of plodding detected objects, metal detectors need to be combined with a complimentary subsurface imaging sensor. i.e., GPR(Ground Penetrating Radar). The demining application requires real-time imaging results with centimetre resolution in a highly portable package. We are currently testing a dual sensor ALIS which is a real-time sensor tracking system based on a CCD camera and image processing. In this paper we introduce ALIS systems which we have developed for detection of buried antipersonnel mines and small size explosives. The performance of ALIS has been tested in Cambodia since 2009. More than 80 anti-personnel mines have been detected and removed from local agricultural area. ALIS has cleared more than 70,000 m2 area and returned it to local farmers.

  8. Introduction to "Mediating Chineseness in Cambodia"

    Addendum by Penny Edwards

    2012-09-01

    Full Text Available In 1981, social anthropologist William Willmott declared, “Today, no-one identifies themselves as Chinese in Kampuchea [Cambodia]” (1981:45. He certainly had the authority to publish such a statement. Having conducted sustained fieldwork on Chinese community formation in Cambodia from 1962 to 1963, Willmott offered an unprecedented examination of social structures, political organization, and patterns of identification among urban Chinese in his monographs, The Chinese in Cambodia (1967 and The Political Structure of the Chinese Community in Cambodia (1970. However, subsequent to his research, Chinese communities suffered terribly during the repression of the Lon Nol government between 1970 and 1975 and the atrocities of the Democratic Kampuchea regime. Willmott thus declared Chinese communities—and a willingness to identify as Chinese—destroyed. This understandably pessimistic vision turned out to be unfounded; the next extensive research done on Chinese in Cambodia by Penny Edwards and Chan Sambath in 1995 showed Chinese communities rebuilding. However, the descriptions of these communities showed a complexity of identity formation—from recent immigrants, “the raw Chinese,” to the five “traditional” Chinese dialect groups—that differed markedly from the indexes of identity applied by Willmott in his initial analysis. Academic ideas of how Chineseness should be configured had shifted and complicated; ascribing identity had become increasingly problematic...

    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. Caring for the Dead Ritually in Cambodia

    2012-04-01

    Full Text Available Buddhist conceptions of the after-life, and prescribed rites in relation to the dead, were modified adaptations of brahman ical patterns of religious culture in ancient India. In this article, I demonstrate how Buddhist conceptions, rites and dispositions have been sustained and transformed in a contemporary annual ritual of rising importance in Cambodia, pchum ben. I analyze phcum ben to determine its fundamental importance to the sustenance and coherence of the Khmer family and national identity. Pchum ben is a 15-day ritual celebrated toward the end of the three-month monastic rain retreat season each year. During these 15 days, Buddhist laity attend ritually to the dead, providing special care for their immediately departed kin and other more recently deceased ancestors. The basic aim of pchum ben involves making a successful transaction of karma transfer to one’s dead kin, in order to help assuage their experiences of suffering. The proximate catalyst for pchum ben’s current popularity is recent social and political history in Southeast Asia, especially the traumatic events that occurred nationally in Cambodia during the early 1970s through the 1980s when the country experienced a series of convulsions. Transformations in religious culture often stand in reflexive relationship to social and political change.

    Little is known about the genetic variability of the soil-transmitted nematode, Strongyloides stercoralis, in humans. We sequenced portions of the small subunit rDNA (SSU), including the hyper variable regions (HVR) I and IV from S. stercoralis larvae derived from individuals living in a rural setting in Cambodia. We identified three polymorphic positions, including a previously reported one within the HVR I. HVR IV was invariable. Six different SSU alleles existed in our sample. Although different genotypes of S. stercoralis were found in the same individuals, no heterozygous larvae were found. This indicates that there is no or very little interbreeding between the different genotypes. Further studies are needed to examine if this is because sexual reproduction, which is facultative, is rare in our study area's S. stercoralis population or because what is considered to be S. stercoralis today is actually a complex of closely related species or subspecies.

  13. Avian influenza: the political economy of disease control in Cambodia.

    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.

    Full Text Available Address to the Thailand, Laos, Cambodia Studies Association at the Association for Asian Studies Annual Conference in Toronto, March 16, 2012This event has given me the opportunity to return to almost the beginning of my academic career: my doctoral fieldwork in Cambodia fifty years ago. (It was preceded by fieldwork in an Inuit community in the Ungava, Northern Canada; not relevant here. Rereading my publications from that research has allowed me to relive the excitement of my Cambodian year, living with my wife and child in Phnom Penh apart from a month in Siem Reap, where I could hire a cyclo for ten riels and visit the various ruins of Angkor every afternoon. Research on overseas Chinese was informed by different paradigms in those days. Bill Skinner was a leading thinker in the field, and Maurice Freedman, my mentor and supervisor, was another.

    A cohort of Japanese encephalitis (JE) survivors in Cambodia and Viet Nam were assessed at least 4 months after hospital discharge in order to understand the extent of disability after JE. We used a simple assessment tool which focuses on the impact on daily life. In total, 64 disability assessments were conducted: 38 in Cambodia and 26 in Viet Nam. In Cambodia, 4 (11%) children had severe sequelae, suggesting the children would likely be dependent, 15 (39%) had moderate sequelae and 17 (45%) had mild sequelae. In Viet Nam, two (8%) persons had severe sequelae, five (19%) had moderate sequelae and eight (31%) had mild sequelae. In many JE-endemic areas there are no multi-disciplinary teams with sophisticated equipment to assess patients after JE disease. This assessment tool can assist with patient management and generate data to support the need for programmes to prevent disease and improve outcomes for survivors.

  16. Cambodia: From Dependency to Sovereignty - Emerging National Leadership

    2015-10-01

    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.

  17. French colonial medicine in Cambodia: reflections of governmentality.

    Science.gov (United States)

    Trankell, Ing-Britt; Ovesen, Jan

    2004-04-01

    Studies of colonial medicine, mostly from former British colonies, have shown that colonial medical interventions mostly benefited the European colonisers and often had very little positive effects on the health of the native populations at large. A common assumption is that this was also the case for French colonial medicine in general, and for colonial medicine in Cambodia in particular, and that the unsatisfactory contemporary state of the medical services in the country may be partly explained by its colonial past. As a way to test this assumption, this paper presents an ethnography of colonial medicine in Cambodia in the first decades of the twentieth century. Documents in the Cambodian National Archives provided the primary sources, and their significance was assessed against the background of the authors' experience of medical anthropological research in contemporary Cambodia. Michel Foucault's concept of governmentality is used as the interpretative frame. Elements of colonial governmentality in the medical field included the promotion of modern medicine through the free dispensing of medicines and medical treatment and rudimentary medical training of members of the local population, as well as compulsory vaccinations and surveillance of the colonial subjects. It is concluded that both the idea of medicine as a 'tool of empire' and that of the colonial physician as a humanitarian hero are equally incomplete as general descriptions, and that specific ethnographies of medical policies and practices should be undertaken for particular colonial settings. This paper provides the first anthropological account of colonial medicine in Cambodia.

    Full Text Available A Heckman sample selection approach is employed with the data on Cambodia Socio-Economic Survey CSES-2007 to explore price and non-price factors determining farmers’ crop diversification decision, and consequently affecting diversification intensity. "The findings suggest that high relative price discourages farmers from diversifying crops." Irrigation, agricultural equipment ownership and farming expenditure have significantly positive effects on the decision, and sequentially increasing the intensity. Arable land size per household member, agricultural and transportation equipments have positive correlation with the diversification decision. Small scale of farming is a major hindrance to the decision, and consequently reducing the intensity. Land dispute, one of the main institutional matters in Cambodia, is found to have significantly negative marginal-effect on farmers’ decision on crop diversification.

    ALIS is a hand-held dual sensor developed by Tohoku University, Japan since 2002. Dual sensor is a general name of sensor for humanitarian demining, which are equipped with metal detector and GPR. ALIS is only one hand-held dual sensor, which can record the sensor position with sensor signals. Therefore, the data can be processed after data acquisition, and can increase the imaging capability. ALIS has been tested in some mine affected courtiers including Afghanistan (2004), Egypt(2005), Croatia(2006-) and Cambodia(2007-). Mine fields at each country has different conditions and soil types. Therefore testes at the real mine fields are very important. ALIS has detected more than 30 AP-Mines in evaluation test in Cambodia held in 2009.

    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.

  5. 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.

    Hong, Rathmony; Ahn, Pauline Yongeun; Rathavy, Tung; Gauthier, Ludovic; Hong, Rathavuth; Laillou, Arnaud

    2017-01-01

    Background 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. Methods/Findings Data was drawn from Demographic Health Surveys (2000, 2005, 2010, 2014). Information on a series of demographic and socio-economic household characteristics and on child anthropometry, feeding practices and child health were collected from nationally representative samples. To reach the required sample size, live-births that occurred over the past 10 years before the date of the interview were included. Demographic variables included: gender of the child, living area (urban or rural; four ecological regions (constructed by merging provinces and the capital), mother’s age at birth (asset-based index). Data on antenatal care, tetanus injection and skilled assistance at birth were used for the

    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.

    Blood counts, hemoglobin (Hb) high performance liquid chromatography (HPLC), and DNA analyses were performed on 260 children, aged 5 months to 16 years, at Siem Reap to assess the prevalence of thalassemia and other hemoglobinopathies in regional Cambodia. Hemoglobinopathies were present in 134 children (51.5%) with 20 abnormal genotypes identified. alpha-Thalassemia (thal) (35.4%) was the most prevalent disorder and the -alpha3.7 gene deletion was the most common alpha-globin gene abnormality. The - -SEA deletion and nondeletional forms of alpha-thal, Hb Constant Spring [Hb CS, alpha142, Term-->Gln, TAA-->CAA (alpha2)], Hb Paksé [alpha142, Term-->Tyr, TAA-->TAT (alpha2)] and triplicated alpha genes, were also present but at low frequencies. Hb E [beta26(B8)Glu-->Lys, GAG-->AAG] (28.8%) was the most common beta-globin gene abnormality, whilst beta-thal was only detected in two children (0.8% of cases). Although hemoglobinopathies were common, the majority of abnormalities detected (heterozygous -alpha3.7 and Hb E) were not clinically significant. On the basis of these findings, and with the majority of abnormalities being mild, it seems improbable that thalassemia represents a major health burden in this region of Cambodia.

    In order to evaluate the circulation of hantaviruses present in southeast Asia, a large scale survey of small mammal species was carried out at seven main sites in the region (Cambodia, Lao People's Democratic Republic, and Thailand). Small scale opportunistic trapping was also performed at an eighth site (Cambodia). Using a standard IFA test, IgG antibodies reacting to Hantaan virus antigens were detected at six sites. Antibody prevalence at each site varied from 0 to 5.6% with antibodies detected in several rodent species (Bandicota indica, B. savilei, Maxomys surifer, Mus caroli, M. cookii, Rattus exulans, R. nitidius, R. norvegicus, and R. tanezumi). When site seroprevalence was compared with site species richness, seropositive animals were found more frequently at sites with lower species richness. In order to confirm which hantavirus species were present, a subset of samples was also subjected to RT-PCR. Hantaviral RNA was detected at a single site from each country. Sequencing confirmed the presence of two hantavirus species, Thailand and Seoul viruses, including one sample (from Lao PDR) representing a highly divergent strain of Seoul virus. This is the first molecular evidence of hantavirus in Lao PDR and the first reported L segment sequence data for Thailand virus.

    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.

    Little is known about circulation of influenza and other respiratory viruses in remote populations along the Thai-Cambodia border in western Cambodia. We screened 586 outpatients (median age 5, range 1–77) presenting with influenza-like-illness (ILI) at 4 sentinel sites in western Cambodia between May 2010 and December 2012. Real-time reverse transcriptase (rRT) PCR for influenza was performed on combined nasal and throat specimens followed by viral culture, antigenic analysis, antiviral susceptibility testing and full genome sequencing for phylogenetic analysis. ILI-specimens negative for influenza were cultured, followed by rRT-PCR for enterovirus and rhinovirus (EV/RV) and EV71. Influenza was found in 168 cases (29%) and occurred almost exclusively in the rainy season from June to November. Isolated influenza strains had close antigenic and phylogenetic relationships, matching vaccine and circulating strains found elsewhere in Cambodia. Influenza vaccination coverage was low (EV71 was found. Despite proximity to Thailand, influenza epidemiology of these western Cambodian isolates followed patterns observed elsewhere in Cambodia, continuing to support current vaccine and treatment recommendations from the Cambodian National Influenza Center. Amino acid mutations at non-epitope sites, particularly hemagglutinin genes, require further investigation in light of an increasingly important role of permissive mutations in influenza virus evolution. Further research about the burden of adenovirus and non-polio enteroviruses as etiologic agents in acute respiratory infections in Cambodia is also needed. PMID:27028323

    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

    2012-11-06

    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.

    2015-05-01

    After almost 25 years of dictatorship and civil war, in the mid 1990s, Cambodia was in dire need of improvement of its medical infrastructure on all levels. Attention had already been focused on establishing primary care services such as emergency surgery, paediatrics and gynaecology/obstetrics; however dermatovenereology services had so far not been addressed. Using a comprehensive approach aiming at sustainable development, German, French and Cambodian institutions worked together to identify four core areas in need of improvement: postgraduate training, development of skin clinics, quality management, and integration of dermatology services into the health insurance scheme. Since 2005, this "Masterplan Dermatology" was financially supported by the Centre for International Migration and Development (CIM) based in Frankfurt am Main and Else Kröner Fresenius-Stiftung (EKFS) based in Bad Homburg auf der Höhe. Significant improvements have been made due to the efforts of the above institutions with the support of the donors; however challenges of this complex endeavor still remain.

    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.

    Following the destruction of Cambodia's health infrastructure during the Khmer Rouge period (1975-1979) and the subsequent decade of United Nations sanctions, international development assistance has focused on reconstructing the country's health system. The recognition of Cambodia's heavy burden of tuberculosis (TB) and the lapse of TB control strategies during the transition to democracy prompted the national tuberculosis programme's relaunch in the mid-1990s as WHO-backed health sector reforms were introduced. This paper examines the conflicts that arose between health reforms and TB control programmes due to their different operating paradigms. It also discusses how these tensions were resolved during introduction of the DOTS strategy for TB treatment.

    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.

  9. Use of Antenatal Services in Kampung District, Cambodia

    Full Text Available This study was conducted to assess factors that influence use of antenatal care services with both quantitative and qualitative designs. Methods used were structured questionnaire interviews and focus group discussions in the Kampung District, Kampot Province in Cambodia with a volunteer sample of 260 postnatal mothers. The outcome measure was factors influencing use of antenatal care services. The results showed that first-time mothers (primigravidas were more likely to use antenatal services than multiparous mothers (OR = 1.87; p = 0.001. Mothers with some school education used antenatal services more than those with no school education (OR = 2.0; p = 0.01. Mothers engaged in professional occupations by virtue of their higher levels of educational attainment were more likely to use antenatal services than those engaged in agriculture (OR = 2.54; p = 0.001. Use of antenatal care services was higher in the districts whose health centers were supported by a foreign nongovernmental organization as compared to other districts with no such support (OR = 2.44; p = 0.001. Although services were generally inadequate, those that existed were underutilized by the mothers. Major factors influencing use of services include distance, lack of transport, and lack of awareness of the benefits of antenatal care by the mothers, thus resulting in a general notion that antenatal care is only important when problems occur during pregnancy. It is concluded that for remote villages, mobile antenatal clinics should be provided to improve access, and greater emphasis should be placed on health educating the mothers about the potential benefits of antenatal care, with special attention to multiparous mothers and those from the lower socio-economic class, among whom use of antenatal services was lowest.

    Full Text Available 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.

    Full Text Available Little is known about circulation of influenza and other respiratory viruses in remote populations along the Thai-Cambodia border in western Cambodia. We screened 586 outpatients (median age 5, range 1-77 presenting with influenza-like-illness (ILI at 4 sentinel sites in western Cambodia between May 2010 and December 2012. Real-time reverse transcriptase (rRT PCR for influenza was performed on combined nasal and throat specimens followed by viral culture, antigenic analysis, antiviral susceptibility testing and full genome sequencing for phylogenetic analysis. ILI-specimens negative for influenza were cultured, followed by rRT-PCR for enterovirus and rhinovirus (EV/RV and EV71. Influenza was found in 168 cases (29% and occurred almost exclusively in the rainy season from June to November. Isolated influenza strains had close antigenic and phylogenetic relationships, matching vaccine and circulating strains found elsewhere in Cambodia. Influenza vaccination coverage was low (<20%. Western Cambodian H1N1(2009 isolate genomes were more closely related to 10 earlier Cambodia isolates (94.4% genome conservation than to 13 Thai isolates (75.9% genome conservation, despite sharing the majority of the amino acid changes with the Thai references. Most genes showed signatures of purifying selection. Viral culture detected only adenovirus (5.7% and parainfluenza virus (3.8%, while non-polio enteroviruses (10.3% were detected among 164 culture-negative samples including coxsackievirus A4, A6, A8, A9, A12, B3, B4 and echovirus E6 and E9 using nested RT-PCR methods. A single specimen of EV71 was found. Despite proximity to Thailand, influenza epidemiology of these western Cambodian isolates followed patterns observed elsewhere in Cambodia, continuing to support current vaccine and treatment recommendations from the Cambodian National Influenza Center. Amino acid mutations at non-epitope sites, particularly hemagglutinin genes, require further investigation in

    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

    In 2013, an unusual increase in the number of Salmonella enterica serotype Paratyphi A (Salmonella Paratyphi A) infections was reported in patients in Phnom Penh, Cambodia, and in European, American and Japanese travellers returning from Cambodia. Epidemiological investigations did not identify a common source of exposure. To analyse the population structure and genetic diversity of these Salmonella Paratyphi A isolates, we used whole-genome sequencing on 65 isolates collected from 1999 to 2014: 55 from infections acquired in Cambodia and 10 from infections acquired in other countries in Asia, Africa and Europe. Short-read sequences from 80 published genomes from around the world and from 13 published genomes associated with an outbreak in China were also included. Pulsed-field gel electrophoresis (PFGE) was performed on a subset of isolates. Genomic analyses were found to provide much more accurate information for tracking the individual strains than PFGE. All but 2 of the 36 isolates acquired in Cambodia during 2013–2014 belonged to the same clade, C5, of lineage C. This clade has been isolated in Cambodia since at least 1999. The Chinese outbreak isolates belonged to a different clade (C4) and were resistant to nalidixic acid, whereas the Cambodian outbreak isolates displayed pan-susceptibility to antibiotics. Since 2014, the total number of cases has decreased, but there has been an increase in the frequency with which nalidixic acid-resistant C5 isolates are isolated. The frequency of these isolates should be monitored over time, because they display decreased susceptibility to ciprofloxacin, the first-choice antibiotic for treating paratyphoid fever.

    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.

    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.

    Sokrin Khun

    Full Text Available 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.

    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.

    Typhoid fever, caused by the bacterium Salmonella Typhi, is an endemic cause of febrile disease in Cambodia. The aim of this study was to better understand the epidemiology of pediatric typhoid fever in Cambodia. We accessed routine blood culture data from Angkor Hospital for Children (AHC) in Siem Reap province between 2007 and 2014, and performed whole genome sequencing (WGS) on the isolated bacteria to characterize the S. Typhi population. The resulting phylogenetic information was combined with conventional epidemiological approaches to investigate the spatiotemporal distribution of S. Typhi and population-level risk factors for reported disease. During the study period, there were 262 cases of typhoid within a 100 km radius of AHC, with a median patient age of 8.2 years (IQR: 5.1-11.5 years). The majority of infections occurred during the rainy season, and commune incidences as high as 11.36/1,000 in children aged typhoid fever in rural communes in Cambodia. Our data provide a platform for additional population-based typhoid fever studies in this location, and suggest that this would be a suitable setting in which to introduce a school-based vaccination programme with Vi conjugate vaccines.

    The risk of nuclear or dirty bomb attack by terrorists is one of the most urgent and threatening danger. The Cambodian national strategy to combat weapons of mass destruction (WMD) depicts a layered system of preventive measures ranging from securing materials at foreign sources to interdicting weapons or nuclear or other radioactive materials at ports, border crossings, and within the Cambodian institutions dealing with the nuclear security to manage the preventive programs. The aim of this study is to formulate guidance, to identify scenario of threat and risk, and to pinpoint necessary legal frameworks on nuclear security in the context of counterterrorism based on the International Atomic Energy Agency nuclear security series. The analysis of this study is guided by theoretical review, the review of international laws and politics, by identifying and interpreting applicable rules and norms establishing the nuclear security regime and how well enforcement of the regime is carried out and, what is the likelihood of the future reform might be. This study will examine the existing national legal frameworks of Cambodia in the context of counterterrorism to prevent acts of nuclear terrorism and the threat of a terrorist nuclear attack within the Cambodia territory. It will shed light on departmental lanes of national nuclear security responsibility, and provide a holistic perspective on the needs of additional resources and emphasis regarding nuclear security policy in the context of counterterrorism in Cambodia.

    The objective of this study was to identify correlates of household food insecurity and poor dietary diversity in rural Cambodia. Trained interviewers administered a survey to 900 households in four rural districts of Prey Veng Province, Cambodia. The Household Food Insecurity Access Scale (HFIAS) and Household Dietary Diversity Score (HDDS) were used to assess household food insecurity and dietary diversity. Multivariate logistic regression models were constructed to identify independent correlates of household food insecurity and poor dietary diversity (HDDSfood insecurity were 33%, 37%, and 12%; and 23% of households had an HDDSfood security status, although the latter association lost its significance in models that adjusted for household income. Similarly, although ownership of agricultural and homestead land was initially associated with poorer dietary diversity, income mitigated these associations. The presence of electricity and vegetable production were the only other variables that were significantly associated with both outcomes. In this rural area of Cambodia, the prevalence of any degree of household food insecurity was very high and dietary diversity was generally low. Interventions to improve food security and dietary diversity should encompass income-generating activities and be targeted toward the poorest households.

    There is little information available on parasites of zoonotic significance in Cambodia. In 2011, in an effort to obtain data on potentially zoonotic gastrointestinal parasites in domestic animals, 50 dogs and 30 pigs residing in 38 households located in Ang Svay Check village, Takeo province, Cambodia were examined for parasites from faecal samples. The samples were processed using the formalin-ethyl acetate concentration technique (FECT). Hookworms were the most common zoonotic parasite found in dogs (80.0%) followed by Echinostomes (18.0%). While, in pigs, Fasciolopsis buski was the most common zoonotic parasite (30.0%) followed by Ascaris suum (13.3%). This study provides baseline data on gastrointestinal parasites in dogs and pigs from Cambodia and underscores the importance of domestic animals as reservoir hosts for human parasites for Cambodian veterinary and public health agencies. Follow-up studies are required to further taxonomically characterize these dog and pig parasites and to determine their role in human parasites in this community.

    Full Text Available Abstract Background One-third of all new HIV infections in Cambodia are estimated to be due to mother-to-child transmission. Although the Ministry of Health adopted a policy of provider-initiated HIV testing and counseling (PITC, nearly a quarter of pregnant mothers were not tested in 2007. Greater acceptance of HIV testing is a challenge despite Cambodia's adoption of the PITC policy. Methods A hospital-based quantitative and cross-sectional survey was conducted to assess the prevalence of and barriers to HIV testing among mothers after delivery at the National Maternal and Child Health Center in Phnom Penh. The Center is one of the largest maternal and child care hospitals in the country to offer PITC services. All 600 eligible mothers who were admitted to the hospital after delivery from October to December 2007 were approached and recruited. Data were collected via a semi-structured questionnaire. Results The prevalence of HIV testing among women who delivered at the hospital was 76%. In multivariate logistic regression, factors such as the perceived need to obtain a partner's permission to be tested (OR=0.27, 95% CI=0.14-0.51, p Conclusion To achieve greater acceptance of HIV testing, counseling on HIV prevention and treatment must be provided not only to mothers but also to their partners. In addition, utilization of non-laboratory staff such as midwives to provide HIV testing services in rural health facilities could lead to the greater acceptance of HIV testing.

    Large alluvial deltas of the Mekong River in southern Vietnam and Cambodia and the Red River in northern Vietnam have groundwaters that are exploited for drinking water by private tube-wells, which are of increasing demand since the mid-1990s. This paper presents an overview of groundwater arsenic pollution in the Mekong delta: arsenic concentrations ranged from 1-1610 {mu}g/L in Cambodia (average 217 {mu}g/L) and 1-845 {mu}g/L in southern Vietnam (average 39 {mu}g/L), respectively. It also evaluates the situation in Red River delta where groundwater arsenic concentrations vary from 1-3050 {mu}g/L (average 159 {mu}g/L). In addition to rural areas, the drinking water supply of the city of Hanoi has elevated arsenic concentrations. The sediments of 12-40 m deep cores from the Red River delta contain arsenic levels of 2-33 {mu}g/g (average 7 {mu}g/g, dry weight) and show a remarkable correlation with sediment-bound iron. In all three areas, the groundwater arsenic pollution seem to be of natural origin and caused by reductive dissolution of arsenic-bearing iron phases buried in aquifers. The population at risk of chronic arsenic poisoning is estimated to be 10 million in the Red River delta and 0.5-1 million in the Mekong delta. A subset of hair samples collected in Vietnam and Cambodia from residents drinking groundwater with arsenic levels > 50 {mu}g/L have a significantly higher arsenic content than control groups (< 50 {mu}g/L). Few cases of arsenic related health problems are recognized in the study areas compared to Bangladesh and West Bengal. This difference probably relates to arsenic contaminated tube-well water only being used substantially over the past 7 to 10 years in Vietnam and Cambodia. Because symptoms of chronic arsenic poisoning usually take more than 10 years to develop, the number of future arsenic related ailments in Cambodia and Vietnam is likely to increase. Early mitigation measures should be a high priority.

    Conclusions: Despite substantial investments, important research areas appear to have been neglected in Cambodia; specifically, studies on TB and studies involving economic, qualitative, interventional, and genomics methods. The inter-disease disparity in published research in Cambodia identified, considered alongside disease burden, suggests that an increase in TB research may be needed to inform control strategies.

    To evaluate the current status of arsenic exposure in the Mekong River basin of Cambodia, field interview along with urine sample collection was conducted in the arsenic-affected area of Kandal Province, Cambodia. Urine samples were analyzed for total arsenic concentrations by inductively coupled plasma mass spectrometry. As a result, arsenicosis patients (n = 127) had As in urine (UAs) ranging from 3.76 to 373 µg L(-1) (mean = 78.7 ± 69.8 µg L(-1); median = 60.2 µg L(-1)). Asymptomatic villagers (n = 108) had UAs ranging from 5.93 to 312 µg L(-1) (mean = 73.0 ± 52.2 µg L(-1); median = 60.5 µg L(-1)). About 24.7 % of all participants had UAs greater than 100 µg L(-1) which indicated a recent arsenic exposure. A survey found that females and adults were more likely to be diagnosed with skin sign of arsenicosis than males and children, respectively. Education level, age, gender, groundwater drinking period, residence time in the village and amount of water drunk per day may influence the incidence of skin signs of arsenicosis. This study suggests that residents in Kandal study area are currently at risk of arsenic although some mitigation has been implemented. More commitment should be made to address this public health concern in rural Cambodia.

    Cynomolgus monkeys as nonhuman primates are valuable animal models because they have a high level of human gene homology. There are many reference values for hematology and biochemistry of Cynomolgus monkeys that are needed for proper clinical diagnosis and biomedical research conduct. The body weight information and blood type are also key success factors in allogeneic or xenogeneic models. Moreover, the biological parameters could be different according to the origin of the Cynomolgus monkey. However, there are limited references provided, especially of Cambodia origin. In this study, we measured average body weight of 2,518 Cynomolgus monkeys and analyzed hematology and serum biochemistry using 119 males, and determined blood types in 642 monkeys with Cambodia origin. The average body weight of male Cynomolgus monkeys were 2.56±0.345 kg and female group was 2.43±0.330 kg at the age from 2 to 3 years. The male group showed relatively sharp increased average body weight from the 3 to 4 age period compared to the female group. In hematology and biochemistry, it was found that most of the data was similar when compared to other references even though some results showed differences. The ABO blood type result showed that type A, B, AB, and O was approximately 15.6, 33.3, 44.2, and 6.9%, respectively. The main blood type in this facility was B and AB. These biological background references of Cambodia origin could be used to provide important information to researchers who are using them in their biomedical research.

    Mercury (Hg) concentrations in human hair and fish samples from Phnom Penh, Kien Svay, Tomnup Rolork and Batrong, Cambodia, collected in November 1999 and December 2000 were determined to understand the status of contamination, and age- and sex-dependent accumulation in humans and to assess the intake of mercury via fish consumption. Mercury concentrations in human hair ranged from 0.54 to 190 {mu}g/g dry wt. About 3% of the samples contained Hg levels exceeding the no observed adverse effects level (NOAEL) of WHO (50 {mu}g/g) and the levels in some hair samples of women also exceeded the NOAEL (10 {mu}g/g) associated with fetus neurotoxicity. A weak but significant positive correlation was observed between age and Hg levels in hair of residents. Mercury concentrations in muscle of marine and freshwater fish from Cambodia ranged from <0.01 to 0.96 {mu}g/g wet wt. Mercury intake rates were estimated on the basis of the Hg content in fish and daily fish consumption. Three samples of marine fish including sharp-tooth snapper and obtuse barracuda, and one sample of sharp-tooth snapper exceeded the guidelines by US EPA and by Joint FAO/WHO Expert Committee on Food Additives (JECFA), respectively, which indicates that some fish specimens examined (9% and 3% for US EPA and JECFA guidelines, respectively) were hazardous for consumption at the ingestion rate of Cambodian people (32.6 g/day). It is suggested that fish is probably the main source of Hg for Cambodian people. However, extremely high Hg concentrations were observed in some individuals and could not be explained by Hg intake from fish consumption, indicating some other contamination sources of Hg in Cambodia. - A source other than fish may be responsible for high Hg in some Cambodians.

    Full Text Available Introduction Cambodia is one of the countries in the world which experienced the most radical disruption of its land tenure. Almost its entire present adult population has been forced at one time or another to leave its lands and houses, whether because of the American bombings (1969-1973 which were particularly murderous in the south-eastern part of the country (the bombs’ holes are still visible from an airplane; or on a far greater scale, during the Democratic Kampuchea regime, called th...

    Full Text Available The sale of tarantulas for either human consumption or for preparation of medicines has become more widespread in Cambodia over the last 10-20 years. With increased media exposure, the trade seems to be increasing, but there are serious questions as to its sustainability because of possible over-collecting of the spiders and also loss of habitats. This note outlines some of the fundamental questions that need to be addressed if this spider trade is to be sustainable or else we could see the loss of an important link in the forest food chain.

    To assess arsenic contaminations and its possible adverse health effects, food samples were collected from Kandal, Kratie and Kampong Cham in Cambodia. The highest and the lowest concentrations were observed in fish (mean 2,832 ng g(-1), ww) collected from Kandal province and cattle stomach (1.86 ± 1.10 ng g(-1), ww) collected from Kratie, respectively. The daily intake of arsenic via food consumption was 604, 9.70 and 136 μg day(-1) in Kandal, Kratie and Kampong Cham, respectively. The arsenic dietary intake in Kandal ranked No. 1 among all the 17 compared countries or regions. Fish consumption contributed the greatest proportion of total arsenic daily intake in Kandal (about 63.0 %) and Kampong Cham (about 69.8 %). It is revealed to be a much more important exposure pathway than drinking water for residents in Kampong Cham. The results of risk assessment suggested that the residents in Cambodia, particularly for people in Kandal province, suffer high public health risks due to consuming arsenic-contaminated food.

    Opisthorchis viverrini is a medically important foodborne parasite in the Indochina Peninsula. In Cambodia, the prevalence of this trematode has been reported in Takeo Province, but not in other areas. In this study, we investigated the prevalence of O. viverrini infection among people in seven riparian villages along the Mekong River, Kratie Province. We also examined the status of metacercarial infection in fish hosts. Fecal specimens were collected from 2101 residents and schoolchildren, and were examined by the Kato-Katz technique. The average O. viverrini egg positive rate was 4.6%, with the highest prevalence found in Roka Kandal A village (10.4%) followed by Talous village (5.9%). In these villages, adult residents showed higher prevalences (19.4% and 9.0%, respectively) than schoolchildren (6.4% and 1.4%, respectively). O. viverrini adult worms were recovered from 2 egg-positive cases (18 and 4 specimens) after praziquantel treatment and purgation. In addition, three of seven freshwater fish species caught near the villages were positive for O. viverrini metacercariae. A total of 367 metacercariae were harvested from 19 infected fish (metacercarial density; 19 per fish). The species of the metacercariae was confirmed through adult worm recovery by experimental infection to hamsters. The results provide evidence that the surveyed areas of Kratie Province, Cambodia, are endemic for O. viverrini infection.

    Opisthorchis viverrini infection was found to be highly prevalent in 3 riverside villages (Ang Svay Chek A, B, and C) of the Prey Kabas District, Takeo Province. This area is located in the southern part of Cambodia, where the recovery of adult O. viverrini worms was recently reported. From May 2006 until May 2010, fecal examinations were performed on a total of 1,799 villagers using the Kato-Katz thick smear technique. In the 3 villages, the overall positive rate for helminth eggs ranged from 51.7 to 59.0% (av. 57.4%), and the percentage positive for O. viverrini was 46.4-50.6% (47.5%). Other helminths detected included hookworms (13.2%), echinostomes (2.9%), Trichuris trichiura (1.3%), Ascaris lumbricoides (0.6%), and Taenia spp. (0.06%). The prevalence of O. viverrini eggs appeared to reflect a lower infection in younger individuals (20 years). Men (50.4%) revealed a significantly higher (P=0.02) prevalence than women (44.3%). The Ang Svay Chek villages of the Prey Kabas District, Takeo Province, Cambodia have been confirmed to be a highly endemic area for human O. viverrini infection.

  7. Deployment of dual-sensor ALIS for humanitarian demining in Cambodia

    We are in the process of developing a high-resolution landmine scanning system "ALIS" which produces horizontal slices of the shallow subsurface for visualization of buried explosives and inert clutter. As many AP mines contain minimum amounts of metal, metal detectors need to be combined with a complimentary subsurface imaging sensor. Ground Penetrating Radar (GPR) is widely accepted for subsurface sensing in the fields of geology, archaeology and utility detection. The demining application requires real-time imaging results with centimetre resolution in a highly portable package. The key requirement for sharp images of the subsurface is the precise tracking of the geophysical sensor(s) during data collection. We should also notice that GPR system is a very wide band radar system, and equivalent to UWB radar, which has recently been developed for short-range high-accuracy radar. We are testing simplified but effective signal processing for imaging mines. We are currently testing a dual sensor ALIS which is a realtime sensor tracking system based on a CCD camera and image processing. In this paper we introduce the GPR systems which we have developed for detection of buried antipersonnel mines and small size explosives. ALIS has been deployed in Cambodia since 2009 and detected more than 70 mines in mine fields, and returned more than 13ha cleaned fields to local farmers. We also report the current status of ALIS in Cambodia.

    In recent years, Cambodia has demonstrated significant success in specific aspects of immunization with gains through campaign efforts in measles control and polio eradication. In contrast, routine immunization rates have failed to improve over the last five years. In response, the National Immunization Program of the Ministry of Health developed a coverage improvement planning (CIP) process. This paper describes the CIP process in Cambodia, including identified barriers to and strategies for improving coverage. Immunization coverage rose in 8 of 10 pilot districts in the year following the introduction of CIP in 2003. The mean increase in DPT3 coverage across pilot districts on an annual basis was 16%, which provides encouraging early evidence for the effectiveness of the intervention. Factors associated with success in coverage improvement included: (1) development of a needs-based micro-plan, (2) application of performance-based contracting between levels of management, (3) investment in social mobilization, (4) securing finance for health outreach programs and (5) strengthened monitoring systems. Lessons learned will guide program expansion to improve immunization coverage nationally.

    Despite the increased use of vaccination in several Asian countries, Japanese Encephalitis (JE) remains the most important cause of viral encephalitis in Asia in humans with an estimated 68,000 cases annually. Considered a rural disease occurring mainly in paddy-field dominated landscapes where pigs are amplifying hosts, JE may nevertheless circulate in a wider range of environment given the diversity of its potential hosts and vectors. The main objective of this study was to assess the intensity of JE transmission to pigs in a peri-urban environment in the outskirt of Phnom Penh, Cambodia. We estimated the force of JE infection in two cohorts of 15 sentinel pigs by fitting a generalised linear model on seroprevalence monitoring data observed during two four-month periods in 2014. Our results provide evidence for intensive circulation of JE virus in a periurban area near Phnom Penh, the capital and most populated city of Cambodia. Understanding JE virus transmission in different environments is important for planning JE virus control in the long term and is also an interesting model to study the complexity of vector-borne diseases. Collecting quantitative data such as the force of infection will help calibrate epidemiological model that can be used to better understand complex vector-borne disease epidemiological cycles.

  10. Forest plunder in Southeast Asia: an environmental security nexus in Burma and Cambodia.

    Talbott, K; Brown, M

    1998-01-01

    This article discusses the cycle of conversion, consumption, and corruption that undermines the environment and civil society in Cambodia and Burma (Myanmar). In these countries, forests are declining in patterns similar to other Southeast Asian deforestation. Illegal logging, prostitution, and heroin trafficking constitute the bulk of Cambodia's shadow economy. Revenues are used to provide financial support for political causes and build the private wealth of the elite. Major political and guerilla groups and the Cambodian military have been major beneficiaries of logging revenue, supported private sector forestry in many military zones, and facilitated logging and trade. About 40% of land goes to forest concessions granted to Southeast Asian companies, and revenues bypass the regular state budget. In Burma, the cease fire agreements in the early 1990s, led to remote border area forests being opened up to large, nonsustainable commercial timber mining. Land was divided into ethnic and government controlled areas. Timber profits were funneled into a business owned by members of the new ruling force, the SLORC, and used to launder drug exports and profits. Trading partners include Thailand, and most recently, China. It is speculated that deforested areas are replanted with opium poppies, and trade routes carry timber and heroin. The unregulated logging industry and the lack of financial accounting of the timber trade undermine the structures of civil society and good governance. Forest policies appear progressive but are in reality unenforced. Politics and agreements in both countries are closely tied to deforestation issues.

  11. Closing the irrigation deficit in Cambodia: Implications for transboundary impacts on groundwater and Mekong River flow

    2016-04-01

    Rice production in Cambodia, essential to food security and exports, is largely limited to the wet season. The vast majority (96%) of land planted with rice during the wet season remains fallow during the dry season. This is in large part due to lack of irrigation capacity, increases in which would entail significant consequences for Cambodia and Vietnam, located downstream on the Mekong River. Here we quantify the extent of the dry season "deficit" area in the Cambodian Mekong River catchment, using a recent agricultural survey and our analysis of MODIS satellite data. Irrigation of this land for rice production would require a volume of water up to 31% of dry season Mekong River flow to Vietnam. However, the two countries share an aquifer system in the Mekong Delta, where irrigation demand is increasingly met by groundwater. We estimate expansion rates of groundwater-irrigated land to be >10% per year in the Cambodian Delta using LANDSAT satellite data and simulate the effects of future expansion on groundwater levels over a 25-year period. If groundwater irrigation continues to expand at current rates, the water table will drop below the lift limit of suction pump wells, used for domestic supply by >1.5 million people, throughout much of the area within 15 years. Extensive groundwater irrigation jeopardizes access for shallow domestic water supply wells, raises the costs of pumping for all groundwater users, and may exacerbate arsenic contamination and land subsidence that are already widespread hazards in the region.

  12. Diversity of Monogononta rotifer species among standing waterbodies in northern Cambodia

    2014-08-01

    Full Text Available The incidence and abundance of Monogononta rotifer species were recorded from lakes and reservoirs in the upper part of the Cambodian Mekong River basin in April and November 2010. One hundred and seven species are reported, 25 of which are new records to Cambodia and 8 taxa were unidentifiable to species level. Species richness at the regional and local scale was not significantly different between habitat types or between seasons, whether it was estimated using incidence or abundance data. Comparison of incidence data also revealed no significant difference from species richness of ponds concurrently sampled in the same region. There appeared to be a high level of diversity among sites that could not be attributed to nestedness or to the 5 environmental variables measured. Each habitat type and season offered substantially different rotifer communities, with the proportion of unshared species between sample sets ranging from 14-49%. Non-metric multidimensional scaling and PERMANOVA analyses also revealed clustering and significant differences among sample sets based on habitat type and season. Therefore, each habitat type and season contributed to the overall rotifer biodiversity. When the incidence data from this study are combined with those in previously reported studies, the overall species richness estimate for Cambodia is 403 species (95% CI = 386-432 and the number of species records has reached 306. 

  13. Resistance and Contingent Contestations to Large-Scale Land Concessions in Southern Laos and Northeastern Cambodia

    2017-02-01

    Full Text Available Over the last decade, there have been considerable concerns raised regarding the social and environmental impacts of large-scale land concessions for plantation development in various parts of the world, especially in the tropics, including in Laos and Cambodia. However, there is still much to learn about the various connections and interactions associated with reactions to what are often referred to as “land grabs”, and the ways they are associated or not associated with broader social movements and networks opposed to land grabbing. There is also the need to develop language for discussing these circumstances, something I aim to contribute to in this article. Here, I present four different cases of types of resistance, or what I refer to as contingent contestations, to land concessions in southern Laos and northeastern Cambodia (two from each country, focusing on the perspectives and associated strategies of smallholder farmers, but without ignoring broader issues. I consider the roles of locals in these contestations, through emphasizing the importance of histories, identities/ethnicities, politics, and geography in determining the types of responses to these land deals that emerge, and the strategies that are adopted for contesting these developments.

  14. Subsurface Imaging by UWB Radar: Application to Humanitarian Demining in Cambodia

    Sato, Motoyuki

    Ground Penetrating Radar (GPR) has been widely used applications which include detection of subsurface facilities, concrete inspection and archaeology. Among these applications, humanitarian demining is still difficult task. Since 2002, we have developed a new hand-held land mine detection dual-sensor ALIS. ALIS is equipped with a metal detector and a GPR, and it has a sensor tracking system, which can record the GPR and Metal detector signal with its location. ALIS can process the data and is used for image re-construction by migration processing. ALIS is the only one mine detection system in the world which can visualize the GPR image by hand scanning. We found that the migration processing can reduce the clutter and gives us clear images of buried mines. After several tests of ALIS in mine affected courtiers, operation of ALIS in mine fields in Cambodia started in summer 2009. Two sets of ALIS have been operated in Cambodia and more than 77 antipersonnel mines have been detected and 137,000m2 farmland was cleaned.

  4. Trauma and Poor Mental Health in Relation to Economic Status: The Case of Cambodia 35 Years Later.

    Johan Jarl

    Full Text Available Cambodia is one of the poorest countries in south-east Asia and is still emerging from the events of the Khmer Rouge reign. It has been suggested that the atrocities experienced by the Cambodian population can explain why Cambodia continues to lag behind its neighbours in economic outcomes. The purpose of this study is to investigate whether there is an association between exposure to past trauma and/or current poor mental health and current economic status in Cambodia.A newly conducted survey performed in two regions (north-west and south-east Cambodia collected information on trauma exposure, psychiatric symptoms, self-rated health outcomes and socio-economic information for 3200 persons aged 18-60. Economic outcomes were measured as household debt and poverty status and whether the respondent was economically inactive. All models were analysed using logistic regression.No association was found between high exposure to conflict-related or civilian trauma and any economic outcomes save for a negative association between civilian trauma and poverty in the south-east. Current post-traumatic stress was related solely to poverty status. All other measures of current mental health status, however, were found to be strongly negatively associated with all measures of economic status. Thus, mental health interventions could potentially be utilised in poverty reduction strategies, but greater efficacy is likely to be achieved by targeting current mental health status rather than previous trauma exposure.

  6. Epidemiological and virological characteristics of influenza viruses circulating in Cambodia from 2009 to 2011.

    Directory of Open Access Journals (Sweden)

    Srey Viseth Horm

    Full Text Available BACKGROUND: The Cambodian National Influenza Center (NIC monitored and characterized circulating influenza strains from 2009 to 2011. METHODOLOGY/PRINCIPAL FINDINGS: Sentinel and study sites collected nasopharyngeal specimens for diagnostic detection, virus isolation, antigenic characterization, sequencing and antiviral susceptibility analysis from patients who fulfilled case definitions for influenza-like illness, acute lower respiratory infections and event-based surveillance. Each year in Cambodia, influenza viruses were detected mainly from June to November, during the rainy season. Antigenic analysis show that A/H1N1pdm09 isolates belonged to the A/California/7/2009-like group. Circulating A/H3N2 strains were A/Brisbane/10/2007-like in 2009 before drifting to A/Perth/16/2009-like in 2010 and 2011. The Cambodian influenza B isolates from 2009 to 2011 all belonged to the B/Victoria lineage represented by the vaccine strains B/Brisbane/60/2008 and B/Malaysia/2506/2004. Sequences of the M2 gene obtained from representative 2009-2011 A/H3N2 and A/H1N1pdm09 strains all contained the S31N mutation associated with adamantanes resistance except for one A/H1N1pdm09 strain isolated in 2011 that lacked this mutation. No reduction in the susceptibility to neuraminidase inhibitors was observed among the influenza viruses circulating from 2009 to 2011. Phylogenetic analysis revealed that A/H3N2 strains clustered each year to a distinct group while most A/H1N1pdm09 isolates belonged to the S203T clade. CONCLUSIONS/SIGNIFICANCE: In Cambodia, from 2009 to 2011, influenza activity occurred throughout the year with peak seasonality during the rainy season from June to November. Seasonal influenza epidemics were due to multiple genetically distinct viruses, even though all of the isolates were antigenically similar to the reference vaccine strains. The drug susceptibility profile of Cambodian influenza strains revealed that neuraminidase inhibitors would be the

    Full Text Available Abstract Background The recent dramatic decline in dihydroartemisinin-piperaquine (DHA-PPQ efficacy in northwestern Cambodia has raised concerns about the rapid spread of piperaquine resistance just as DHA-PPQ is being introduced as first-line therapy in neighbouring countries. Methods Ex vivo parasite susceptibilities were tracked to determine the rate of progression of DHA, PPQ and mefloquine (MQ resistance from sentinel sites on the Thai–Cambodian and Thai–Myanmar borders from 2010 to 2015. Immediate ex vivo (IEV histidine-rich protein 2 (HRP-2 assays were used on fresh patient Plasmodium falciparum isolates to determine drug susceptibility profiles. Results IEV HRP-2 assays detected the precipitous emergence of PPQ resistance in Cambodia beginning in 2013 when 40 % of isolates had an IC90 greater than the upper limit of prior years, and this rate doubled to 80 % by 2015. In contrast, Thai–Myanmar isolates from 2013 to 14 remained PPQ-sensitive, while northeastern Thai isolates appeared to have an intermediate resistance profile. The opposite trend was observed for MQ where Cambodian isolates appeared to have a modest increase in overall sensitivity during the same period, with IC50 declining to median levels comparable to those found in Thailand. A significant association between increased PPQ IC50 and IC90 among Cambodian isolates with DHA-PPQ treatment failure was observed. Nearly all Cambodian and Thai isolates were deemed artemisinin resistant with a >1 % survival rate for DHA in the ring-stage assay (RSA, though there was no correlation among isolates to indicate cross-resistance between PPQ and artemisinins. Conclusions Clinical DHA-PPQ failures appear to be associated with declines in the long-acting partner drug PPQ, though sensitivity appears to remain largely intact for now in western Thailand. Rapid progression of PPQ resistance associated with DHA-PPQ treatment failures in northern Cambodia limits drugs of choice in

    2009-01-01

    Full Text Available Abstract Background The combination of artesunate and mefloquine was introduced as the national first-line treatment for Plasmodium falciparum malaria in Cambodia in 2000. However, recent clinical trials performed at the Thai-Cambodian border have pointed to the declining efficacy of both artesunate-mefloquine and artemether-lumefantrine. Since pfmdr1 modulates susceptibility to mefloquine and artemisinin derivatives, the aim of this study was to assess the link between pfmdr1 copy number, in vitro susceptibility to individual drugs and treatment failure to combination therapy. Methods Blood samples were collected from P. falciparum-infected patients enrolled in two in vivo efficacy studies in north-western Cambodia: 135 patients were treated with artemether-lumefantrine (AL group in Sampovloun in 2002 and 2003, and 140 patients with artesunate-mefloquine (AM group in Sampovloun and Veal Veng in 2003 and 2004. At enrollment, the in vitro IC50 was tested and the strains were genotyped for pfmdr1 copy number by real-time PCR. Results The pfmdr1 copy number was analysed for 115 isolates in the AM group, and for 109 isolates in the AL group. Parasites with increased pfmdr1 copy number had significantly reduced in vitro susceptibility to mefloquine, lumefantrine and artesunate. There was no association between pfmdr1 polymorphisms and in vitro susceptibilities. In the patients treated with AM, the mean pfmdr1copy number was lower in subjects with adequate clinical and parasitological response compared to those who experienced late treatment failure (n = 112, p p = 0.364. The presence of three or more copies of pfmdr1 were associated with recrudescence in artesunate-mefloquine treated patients (hazard ratio (HR = 7.80 [95%CI: 2.09–29.10], N = 115, p = 0.002 but not with recrudescence in artemether-lumefantrine treated patients (HR = 1.03 [95%CI: 0.24–4.44], N = 109, p = 0.969.

    Full Text Available Abstract Background Malaria-endemic countries are switching antimalarial drug policy to artemisinin combination therapies (ACTs and the global community are considering the setting up of a global subsidy mechanism in order to make them accessible and affordable. However, specific interventions may be needed to reach remote at-risk communities and to ensure that they are used appropriately. This analysis documents the coverage with ACTs versus artemisinin monotherapies, and the effectiveness of malaria outreach teams (MOTs and Village Malaria Workers (VMWs in increasing access to appropriate diagnosis and treatment with ACTs in Cambodia, the first country to switch national antimalarial drug policy to an ACT of artesunate and mefloquine (A+M in 2000. Methods A cross-sectional survey was carried out in three different types of intervention area: with VMWs, MOTs and no specific interventions. Individuals with a history of fever in the last three weeks were included in the study and completed a questionnaire on their treatment seeking and drug usage behaviour. Blood was taken for a rapid diagnostic test (RDT and data on the household socio-economic status were also obtained. Results In areas without specific interventions, only 17% (42/251 of respondents received a biological diagnosis, 8% (17/206 of respondents who received modern drug did so from a public health facility, and only 8% of them (17/210 received A+M. Worryingly, 78% (102/131 of all artemisinin use in these areas was as a monotherapy. However, both the VMW scheme and MOT scheme significantly increased the likelihood of being seen by a trained provider (Adjusted Odds Ratios (AOR of 148 and 4 respectively and of receiving A+M (AORs of 2.7 and 7.7 respectively. Conclusion The coverage rates of appropriate diagnosis and treatment of malaria were disappointingly low and the use of artemisinin monotherapy alarmingly high. This reflects the fragmented nature of Cambodia's health system in

    Women's diets often decrease with regard to amounts per meal and day as well as diversity if a household's access to food is limited. The result is a monotonous diet that, in particular, negatively affects women's nutritional status during pregnancy and lactation and, thus, the infant. The infant's diet is of utmost importance, as it needs to meet the nutrient requirements especially during the first 2 years of life, a critical window for the child's healthy development. In Cambodia, infant and young child feeding (IYCF) practices are poor. Preparation of a special complementary meal in addition to breast milk feeds for children aged 6-23 months is often not a common habit. Instead, children eat watery, plain rice porridges that do not meet the nutrient requirements at this young age. A lack of adequate caring practices such as responsive feeding exacerbates the risk of malnutrition. Caregivers are often unaware of the importance of nutrition during the first 2 years of life regarding its effects on children's growth. In 2012, a randomized controlled trial (RCT) was started in two provinces of northern Cambodia: Oddar Meanchey and Preah Vihear. To contribute to reducing child mortality by addressing malnutrition among children 6-23 months of age, the Food and Agriculture Organization of the United Nations (FAO) implemented a nutrition-sensitive agriculture project with nutrition-specific actions, i.e. a nutrition education intervention was embedded in a food security project. Wealth, a child's age, and maternal education were identified as determinants of a child's dietary diversity. The older the child and/or the wealthier the household, the more diverse the child's diet. Maternal education was positively associated with the child's dietary diversity. Household dietary diversity was significantly associated with child dietary diversity in a model including group, child's age, maternal education, and wealth as confounders. The RCT also showed that a 2- to 3-month

    Soil-transmitted helminth infections are intimately connected with poverty. Yet, there is a paucity of using socioeconomic proxies in spatially explicit risk profiling. We compiled household-level socioeconomic data pertaining to sanitation, drinking-water, education and nutrition from readily available Demographic and Health Surveys, Multiple Indicator Cluster Surveys and World Health Surveys for Cambodia and aggregated the data at village level. We conducted a systematic review to identify parasitological surveys and made every effort possible to extract, georeference and upload the data in the open source Global Neglected Tropical Diseases database. Bayesian geostatistical models were employed to spatially align the village-aggregated socioeconomic predictors with the soil-transmitted helminth infection data. The risk of soil-transmitted helminth infection was predicted at a grid of 1×1km covering Cambodia. Additionally, two separate individual-level spatial analyses were carried out, for Takeo and Preah Vihear provinces, to assess and quantify the association between soil-transmitted helminth infection and socioeconomic indicators at an individual level. Overall, we obtained socioeconomic proxies from 1624 locations across the country. Surveys focussing on soil-transmitted helminth infections were extracted from 16 sources reporting data from 238 unique locations. We found that the risk of soil-transmitted helminth infection from 2000 onwards was considerably lower than in surveys conducted earlier. Population-adjusted prevalences for school-aged children from 2000 onwards were 28.7% for hookworm, 1.5% for Ascaris lumbricoides and 0.9% for Trichuris trichiura. Surprisingly, at the country-wide analyses, we did not find any significant association between soil-transmitted helminth infection and village-aggregated socioeconomic proxies. Based also on the individual-level analyses we conclude that socioeconomic proxies might not be good predictors at an

    Full Text Available Cambodia’s higher education is under development. This is the first study of the role of women teaching in a university in Cambodia. There has been many studies of academic women in western countries and these guided the 16 interviews in Khmer that were carried out by young female researchers, translated by them and then analysed with the assistance of NVivo. Becoming an academic for many Cambodian women meant support from their parents and others close to them. Receipt of an international scholarship may have been critical. Perhaps the most important issue for these academic women was the need to balance demands on their time. Teaching hours could be negotiated, potentially at least, but only where the student numbers warranted it. An affirmative action approach appears to have developed at one of the two universities. Areas for future research are identified.

    2012-09-01

    Full Text Available In her introduction to this special issue of Cross-Currents, Lorraine Paterson sets the scene for the featured articles and provides the context from which they emerged. This endnote essay works to a reverse formula, seeking if not to unweave then to unsettle the notion of bounded coherence and to spotlight instead the inchoate nature of any project to document the past. Rather than braiding together threads of our contributors' articles to signal the thematic coherence of this suite of papers on “mediating Chineseness,” I work instead from key themes presented in this collection to gesture towards loose ends and unstitched seams. Mirroring the genre of Willmott’s memoir essay, I invite reflection on these in-between spaces and the possibilities they represent for developing new approaches to the articulation, study, and mediation of “Chineseness” in Cambodia.

    The effects of variety and growth location on grain composition and starch structures were investigated using three rice (Oryza sativa L.) cultivars (Phka Romduol, Sen Pidao and IR66) with different amylose contents. All the three cultivars were planted in three different agro-climatic zones (Phnom Penh, Coastal and Plateau) of Cambodia. The protein content of polished grains increased when rice was planted at a location with higher average temperature, but their lipid content decreased. The amylose content and degree of branching were not greatly affected by the minor temperature differences among the growing locations. Starch fine structures characterized by the chain-length distribution were significantly different among the cultivars, but not significantly among different locations. The results suggested that protein and lipid biosyntheses were more sensitive to the environmental temperature than that of starch in rice grains.

    Using a set of statistical methods and HIV mathematical models applied on nationally representative Demographic and Health Survey data, we characterized HIV serodiscordancy patterns and HIV transmission dynamics in stable couples (SCs) in four countries: Cambodia, the Dominican Republic, Haiti, and India. The majority of SCs affected by HIV were serodiscordant, and about a third of HIV-infected persons had uninfected partners. Overall, nearly two-thirds of HIV infections occurred in individuals in SCs, but only about half of these infections were due to transmissions within serodiscordant couples. The majority of HIV incidence in the population occurred through extra-partner encounters in SCs. There is similarity in HIV epidemiology in SCs between these countries and countries in sub-Saharan Africa, despite the difference in scale of epidemics. It appears that HIV epidemiology in SCs may share similar patterns globally, possibly because it is a natural 'spillover' effect of HIV dynamics in high-risk populations.

    We report a case of box-jellyfish related envenomation in a 40 year old tourist that occurred in Sihanoukville, Cambodia, in the Gulf of Thailand. Symptoms that appeared within a few minutes associated intense pain, hand edema and large edematous and erythematous flagellations in the stung skin areas. Antibiotics and corticosteroids were delivered. Inflammatory signs and skin lesions disappeared within 15 days followed by crusts then scars. Jellyfish at risk for humans are generally found in tropical seas and their geographic distribution seems to spread. As it is difficult to prevent this kind of accident, travelers should be aware of the first acts to perform, such as appropriate cleaning of the wound, the interest of vinegar usage, the administration of analgesics and corticosteroids in case of significant inflammatory signs.

    Full Text Available Background: Concerns about the nutritional status of Cambodian garment workers were raised years ago but data are still scarce. The objectives of this study are to examine the nutritional, hemoglobin and micronutrient status of female workers in a garment factory in Phnom Penh, Cambodia, and to assess if body mass index is associated with hemoglobin and/or micronutrient status. Methods: A cross-sectional survey was conducted among 223 female workers (nulliparous, non-pregnant at a garment factory in Phnom Penh. Anthropometric measurements were performed and blood samples were taken to obtain results on hemoglobin, iron, vitamin A, vitamin B12 and inflammation status (hemoglobinopathies not determined. Bivariate correlations were used to assess associations. Results: Overall, 31.4% of workers were underweight, 26.9% showed anemia, 22.1% showed iron deficiency, while 46.5% had marginal iron stores. No evidence of vitamin A or vitamin B12 deficiency was found. Body mass index was associated with serum ferritin (negative and serum retinol-binding protein (positive concentrations, but not strongly. A comparison between underweight and not underweight workers resulted in distinctions for iron deficiency and iron deficiency anemia, with a higher prevalence among not underweight. Conclusions: The prevalence of underweight, anemia and poor iron status was high. Young and nulliparous female garment workers in Cambodia might constitute a group with elevated risk for nutritional deficiencies. Strategies need to be developed for improving their nutritional, micronutrient and health status. The poor iron status seems to contribute to the overall prevalence of anemia. Low hemoglobin and iron deficiency affected both underweight and those not underweight. Despite the fact that body mass index was negatively associated with iron stores, true differences in iron status between underweight and not underweight participants cannot be confirmed.

    In central Cambodia, rapid growing non-endemic species are planted for future timber production. However, less is understood about the impact of the introduction of non-endemic species on the transpiration characteristics of the forest, which has been composed of native species that adapted to the highly seasonal environments. Sap flux of two native and one non-endemic tree species in central Cambodia was measured to reveal its seasonal trends and variability in the Monsoon Asia region. Measurements were carried out in a 10- to 15-year-old forest in the dry and rainy seasons that were defined by differing rainfall patterns. The seasonal trend in depth to water table differed from that of rainfall; groundwater table depth reached zero late in the rainy season and increased gradually after the onset of the dry season. The ratio of sap flux to an equilibrium evaporation condition of the native species, Popel (Shorea roxburghii), showed a sharp decline at the end of the dry season, whereas that of a non-endemic species, eucalyptus (Eucalyptus camaldulensis), decreased in the mid rainy season while Tbeng (Dipterocarpus obtusifolius) did not show a clear trend. The ratio of sap flux to an equilibrium evaporation was negatively correlated with the depth to water table in Popel, but was positively correlated in eucalyptus, possibly because of the negative effects of flooding. In addition to the large seasonal variation, intra-species variation in sap flux was also large and was a major controlling factor for tree-level water uptake at this young forest site in both dry and rainy seasons. In conclusion, the transpiration characteristics of this forest were species-specific and were controlled more by the fluctuating depths to groundwater rather than the onset of the rainy/dry seasons defined by rainfall events.

  2. Emergence of community-associated methicillin-resistant Staphylococcus aureus associated with pediatric infection in Cambodia.

    Kheng Chheng

    Full Text Available BACKGROUND: The incidence of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA infection is rising in the developed world but appears to be rare in developing countries. One explanation for this difference is that resource poor countries lack the diagnostic microbiology facilities necessary to detect the presence of CA-MRSA carriage and infection. METHODOLOGY AND PRINCIPAL FINDINGS: We developed diagnostic microbiology capabilities at the Angkor Hospital for Children, Siem Reap, western Cambodia in January 2006 and in the same month identified a child with severe community-acquired impetigo caused by CA-MRSA. A study was undertaken to identify and describe additional cases presenting between January 2006 and December 2007. Bacterial isolates underwent molecular characterization using multilocus sequence typing, staphylococcal cassette chromosome mec (SCCmec typing, and PCR for the presence of the genes encoding Panton-Valentine Leukocidin (PVL. Seventeen children were identified with CA-MRSA infection, of which 11 had skin and soft tissue infection and 6 had invasive disease. The majority of cases were unrelated in time or place. Molecular characterization identified two independent MRSA clones; fifteen isolates were sequence type (ST 834, SCCmec type IV, PVL gene-negative, and two isolates were ST 121, SCCmec type V, PVL gene-positive. CONCLUSIONS: This represents the first ever report of MRSA in Cambodia, spread of which would pose a significant threat to public health. The finding that cases were mostly unrelated in time or place suggests that these were sporadic infections in persons who were CA-MRSA carriers or contacts of carriers, rather than arising in the context of an outbreak.

    Negotiating safer sex among married women has been identified as an important determinant of vulnerability or resilience to new HIV infections. Using the Cambodia Demographic and Health Survey data of 2010, this paper examined negotiation for safer sex among 11,218 married women in the context of Cambodia's highly touted reduction in HIV/AIDS prevalence. The results from a complementary log-log regression model indicate that wealthier and highly educated married women were more likely to report that they can refuse sexual intercourse and ask their husbands to use a condom. Interestingly, while women who were fully involved in decision-making on their own health care were 19% more likely to refuse sex, they were 14% less likely to be able to ask their husbands to use a condom, compared with their counterparts who were not involved in this decision-making. Women who were partially involved in decision-making on family visits were 17% less likely to be able to ask their husbands to use a condom compared with those who were not involved. In this context, involvement in decision-making may have translated into trust and risk compensation. Those who believed in HIV transmission myths were less likely to negotiate safer sex relative to their counterparts who did not hold such myths to be true. Women's ability to negotiate for safer sex is, therefore, a function of their autonomy in terms of their full participation in decision-making in health care, household expenditure and mobility. Policy implications of the capacity of women to negotiate for safer sex are delineated.

    The aim of this study is to estimate the potential for generating carbon credits from Reducing Emissions from Deforestation and Degradation (REDD) in a region known as the Southern Cardamoms Ecosystem, Southwest Cambodia. Through the last decade, the Southern Cardamom Ecosystem has seen increasing pressures on the forest resources. The Royal government of Cambodia struggled to control degrading forest activities in the area alone and therefore sought the assistance of the NGO Wildlife Alliance in 2002. The option to attain carbon credits from REDD now offers an opportunity to achieve various goals: (1) to conserve the forest, (2) reduce CO2 emissions, (3) support and develop local communities; and (4) generate revenues for the Cambodian government and the NGO Wildlife Alliance. The potential amount of carbon benefits that can be generated has been estimated through an analysis of what is technically possible given the conditions of the project area, such as carbon density and deforestation rate. This technical assessment was complimented by an analysis of the current institutional and social conditions/barriers that can affect the actual quantity of marketable carbon. It was found that the technical potential lies in the range between 0.4 and 1.3 million tCO2/yr. However, the actual emission reductions that can be captured by REDD is dependent on how much deforestation can be reduced, and how effectively the project deals with the issues of permanence and leakage. These three aspects are in turn dependent of several institutional and social-economic factors. While the project is currently in the early phase of development, emphasis must be put on generating benefits for the local people who in reality bear the cost of reducing deforestation. Local people are a vital component to the overall success of the REDD project. Encouraging their participation and cooperation in the project can ensure long-term permanent emission reductions.

    2007-03-01

    Full Text Available Abstract Background In Cambodia, estimates of the malaria burden rely on a public health information system that does not record cases occurring among remote populations, neither malaria cases treated in the private sector nor asymptomatic carriers. A global estimate of the current malaria situation and associated risk factors is, therefore, still lacking. Methods A large cross-sectional survey was carried out in three areas of multidrug resistant malaria in Cambodia, enrolling 11,652 individuals. Fever and splenomegaly were recorded. Malaria prevalence, parasite densities and spatial distribution of infection were determined to identify parasitological profiles and the associated risk factors useful for improving malaria control programmes in the country. Results Malaria prevalence was 3.0%, 7.0% and 12.3% in Sampovloun, Koh Kong and Preah Vihear areas. Prevalences and Plasmodium species were heterogeneously distributed, with higher Plasmodium vivax rates in areas of low transmission. Malaria-attributable fevers accounted only for 10–33% of malaria cases, and 23–33% of parasite carriers were febrile. Multivariate multilevel regression analysis identified adults and males, mostly involved in forest activities, as high risk groups in Sampovloun, with additional risks for children in forest-fringe villages in the other areas along with an increased risk with distance from health facilities. Conclusion These observations point to a more complex malaria situation than suspected from official reports. A large asymptomatic reservoir was observed. The rates of P. vivax infections were higher than recorded in several areas. In remote areas, malaria prevalence was high. This indicates that additional health facilities should be implemented in areas at higher risk, such as remote rural and forested parts of the country, which are not adequately served by health services. Precise malaria risk mapping all over the country is needed to assess the

    Full Text Available Infections with helminths and other intestinal parasites are an important but neglected problem in children in developing countries. Accurate surveys of intestinal parasites in children inform empirical treatment regimens and can assess the impact of school based drug treatment programmes. There is limited information on this topic in Cambodia.In a prospective study of intestinal parasites in symptomatic children attending Angkor Hospital for Children, Siem Reap, Cambodia, April-June 2012, samples were examined by microscopy of a direct and concentrated fecal sample. Two culture methods for hookworm and Strongyloides stercoralis were employed when sufficient sample was received. Demographic, clinical and epidemiological data were collected.We studied 970 samples from 865 children. The median (inter-quartile range age of the children was 5.4 (1.9-9.2 years, 54% were male. The proportion of children with abdominal pain was 66.8%, diarrhea 34.9%, anemia 12.7% and malnutrition 7.4%. 458 parasitic infections were detected in 340 (39.3% children. The most common parasites using all methods of detection were hookworm (14.3%, Strongyloides stercoralis (11.6% and Giardia lamblia (11.2%. Giardia lamblia was most common in children aged 1-5 years, hookworm and Strongyloides stercoralis were more common with increasing age. Hookworm, Strongloides stercoralis and Giardia lamblia were more common in children living outside of Siem Reap town. In a multivariate logistic regression increasing age was associated with all three infections, defecating in the forest for hookworm infection, the presence of cattle for S. stercoralis and not using soap for handwashing for G. lamblia.This study confirms the importance of intestinal parasitic infections in symptomatic Cambodian children and the need for adequate facilities for laboratory diagnosis together with education to improve personal hygiene and sanitation.

  7. Optimising strategies for Plasmodium falciparum malaria elimination in Cambodia: primaquine, mass drug administration and artemisinin resistance.

    Directory of Open Access Journals (Sweden)

    Richard J Maude

    Full Text Available BACKGROUND: Malaria elimination requires a variety of approaches individually optimized for different transmission settings. A recent field study in an area of low seasonal transmission in South West Cambodia demonstrated dramatic reductions in malaria parasite prevalence following both mass drug administration (MDA and high treatment coverage of symptomatic patients with artemisinin-piperaquine plus primaquine. This study employed multiple combined strategies and it was unclear what contribution each made to the reductions in malaria. METHOD AND FINDINGS: A mathematical model fitted to the trial results was used to assess the effects of the various components of these interventions, design optimal elimination strategies, and explore their interactions with artemisinin resistance, which has recently been discovered in Western Cambodia. The modelling indicated that most of the initial reduction of P. falciparum malaria resulted from MDA with artemisinin-piperaquine. The subsequent continued decline and near elimination resulted mainly from high coverage with artemisinin-piperaquine treatment. Both these strategies were more effective with the addition of primaquine. MDA with artemisinin combination therapy (ACT increased the proportion of artemisinin resistant infections, although much less than treatment of symptomatic cases with ACT, and this increase was slowed by adding primaquine. Artemisinin resistance reduced the effectiveness of interventions using ACT when the prevalence of resistance was very high. The main results were robust to assumptions about primaquine action, and immunity. CONCLUSIONS: The key messages of these modelling results for policy makers were: high coverage with ACT treatment can produce a long-term reduction in malaria whereas the impact of MDA is generally only short-term; primaquine enhances the effect of ACT in eliminating malaria and reduces the increase in proportion of artemisinin resistant infections; parasite

    Abstract In order to assess the prevalence of point‐of‐sale promotions of infant and young child feeding products in Phnom Penh, Cambodia; Kathmandu Valley, Nepal; Dakar Department, Senegal; and Dar es Salaam, Tanzania, approximately 30 retail stores per site, 121 in total, were visited. Promotional activity for breastmilk substitutes (BMS) and commercially produced complementary foods in each site were recorded. Point‐of‐sale promotion of BMS occurred in approximately one‐third of sampled stores in Phnom Penh and Dakar Department but in 3.2% and 6.7% of stores in Kathmandu Valley and Dar es Salaam, respectively. Promotion of commercially produced complementary foods was highly prevalent in Dakar Department with half of stores having at least one promotion, while promotions for these products occurred in 10% or less of stores in the other three sites. While promotion of BMS in stores is legal in Senegal, it is prohibited in Cambodia without prior permission of the Ministry of Health/Ministry of Information and prohibited in both Nepal and Tanzania. Strengthening legislation in Senegal and enforcing regulations in Cambodia could help to prevent such promotion that can negatively affect breastfeeding practices. Key messages Even in countries such as Cambodia, Nepal and Tanzania where point‐of‐sale promotion is restricted, promotions of BMS were observed (in nearly one‐third of stores in Phnom Penh and less than 10% in Dar es Salaam and Kathmandu).Limited promotion of commercially produced complementary foods was evident (less than 10% of stores had a promotion for such foods), except in Dakar Department, where promotions were found in half of stores.Efforts are needed to strengthen monitoring, regulation and enforcement of restrictions on the promotion of BMS.Manufacturers and distributors should take responsibility for compliance with national regulations and global policies pertaining to the promotion of breastmilk substitutes.

    Full Text Available Iodine deficiency disorders are estimated to affect over 1.9 million people worldwide. Iodine deficiency is especially serious for women during pregnancy and lactation because of the negative consequences for both mother and infant. The aim of this cross-sectional study was to determine the median urinary iodine concentration (UIC as a population-level indicator of iodine status among rural women farmers of reproductive age (18–45 years in the province of Prey Veng, Cambodia. A total of 450 women provided a spot morning urine sample in 2012. Of those women, 93% (n = 420 were non-pregnant and 7% (n = 30 were pregnant at the time of collection. UIC was quantified using the Sandell-Kolthoff reaction with modifications. The median UIC of non-pregnant (139 μg/L and pregnant women (157 μg/L were indicative of adequate iodine status using the WHO/UNICEF/ICCIDD epidemiological criteria for both groups (median UIC between 100–199 and 150–249 μg/L, respectively. We conclude that non-pregnant and pregnant women in rural Prey Veng, Cambodia had adequate iodine status based on single spot morning urine samples collected in 2012. More research is warranted to investigate iodine status among larger and more representative populations of women in Cambodia, especially in light of recent policy changes to the national program for universal salt iodization.

    Iodine deficiency disorders are estimated to affect over 1.9 million people worldwide. Iodine deficiency is especially serious for women during pregnancy and lactation because of the negative consequences for both mother and infant. The aim of this cross-sectional study was to determine the median urinary iodine concentration (UIC) as a population-level indicator of iodine status among rural women farmers of reproductive age (18-45 years) in the province of Prey Veng, Cambodia. A total of 450 women provided a spot morning urine sample in 2012. Of those women, 93% (n = 420) were non-pregnant and 7% (n = 30) were pregnant at the time of collection.

    Indiscriminate fisheries target multiple species with multiple gear types. In contrast to well-studied, industrialized single-species, single-gear fisheries, little theory and little but growing literature on practice exists for indiscriminate fisheries. Indiscriminate fisheries are disproportionately important in low-income countries, providing most of the animal protein intake in countries such as Cambodia and Bangladesh. Indiscriminate fisheries may be either freshwater or marine, but here we focus on what may be the largest freshwater indiscriminate fishery in the world. Cambodia's freshwater fishery stands out because it provides the majority of animal protein to over 3 million people living in poverty. The fishery of the Tonle Sap lake is one of the largest, if not the largest contributor to this freshwater fish take, and is perhaps the largest freshwater fishery in the world. In contrast to its importance, very little is known about the foodweb ecology of this system, or how community management which now governs the entire fishery, interacts with biological and physical factors such as climate change.The foodweb of the Tonle Sap has changed dramatically due to high fishing pressure. A system that once harbored giant catfish, barbs and stingrays is now dominated by fish under 20cm in length. The simplification of the system may not have reduced its productivity. Theory of indiscriminate fisheries suggests that r-selected species may be favored and that biomass available for harvest may be maximized, while being more sensitive to environmental fluctuations such as climate change due to food web simplification. The r-selection and size predictions of theory have been confirmed by observations of the Tonle Sap. Early model results suggest sensitivity to environmental stochasticity. The interaction of these ecological changes with social systems will be tested in the Tonle Sap. Fisheries management across the lake has been transferred to community management

    The research was carried out at 3 study sites with varying groundwater arsenic (As) levels in the Kandal Province of Cambodia. Kampong Kong Commune was chosen as a highly contaminated site (300–500 μg/L), Svay Romiet Commune was chosen as a moderately contaminated site (50–300 μg/L) and Anlong Romiet Commune was chosen as a control site. Neurobehavioral tests on the 3 exposure groups were conducted using a modified WHO neurobehavioral core test battery. Seven neurobehavioral tests including digit symbol, digit span, Santa Ana manual dexterity, Benton visual retention, pursuit aiming, trail making and simple reaction time were applied. Children's hair samples were also collected to investigate the influence of hair As levels on the neurobehavioral test scores. The results from the inductively coupled plasma-mass spectrometry (ICP-MS) analyses of hair samples showed that hair As levels at the 3 study sites were significantly different (p<0.001), whereby hair samples from the highly contaminated site (n=157) had a median hair As level of 0.93 μg/g, while the moderately contaminated site (n=151) had a median hair As level of 0.22 μg/g, and the control site (n=214) had a median hair As level of 0.08 μg/g. There were significant differences among the 3 study sites for all the neurobehavioral tests scores, except for digit span (backward) test. Multiple linear regression clearly shows a positive significant influence of hair As levels on all the neurobehavioral test scores, except for digit span (backward) test, after controlling for hair lead (Pb), manganese (Mn) and cadmium (Cd). Children with high hair As levels experienced 1.57–4.67 times greater risk of having lower neurobehavioral test scores compared to those with low hair As levels, after adjusting for hair Pb, Mn and Cd levels and BMI status. In conclusion, arsenic-exposed school children from the Kandal Province of Cambodia with a median hair As level of 0.93 µg/g among those from the highly

    Background Text or voice messages containing health behavior change content may be an inexpensive, discreet, sustainable and scalable way to reach populations at high risk for HIV. In Cambodia, one of the important high-risk populations is female entertainment workers (FEWs). This ethnographic study aims to explore typical phone use, examining patterns and behaviors that may influence the design of future mHealth interventions. Methods The study consisted of one 8-hour non-participant observation session for 15 randomly sampled FEWs. Observations focused on capturing normal daily use of mobile devices. Observation checklists were populated by observers during the observations and a post-observation survey was conducted. Findings were discussed with Cambodian HIV outreach workers and HIV research fellows and their interpretations are summarized below. Results In this ethnographic study, all 15 participants made calls, checked the time and received research-related texts. More than half (n=8) of the participants engaged in texting to a non-research recipient. About half (n=7) went on Facebook (FB) and some (n=5) listened to music and looked at their FB newsfeed. Fewer played a mobile game, posted a photo to FB, went on YouTube, used FB chat/messenger, watched a video on FB, played a game on FB, used FB call/voice chat, looked at their phone’s background or used the LINE app. Fewer still shared their phones, left them unattended, added airtime or changed their SIM cards. When participants received a research text message, most did not share the text message with anyone, did not ask for help deciphering the message and did not receive help composing a response. Notable themes from observer notes, HIV outreach workers and researchers include reasons why phone calls were the most frequent mode of communication, examples of how cell phone company text messages are used as a form of behavior change, literacy as a persistent barrier for some FEWs, and FEWs’ high

    To estimate the greenhouse gas emissions from paddy fields of Cambodia, the methodology of the Intergovernmental Panel on Climate Change (IPCC) guidelines, IPCC coefficients, and emission factors from the experiment in Thailand and another country were used. Total area under rice cultivation during the years 2005-2006 was 2,048,360 ha in the first crop season and 298,529 ha in the second crop season. The emission of methane from stubble incorporation with manure plus fertilizer application areas in the first crop season was estimated to be 192,783.74 ton higher than stubble with manure, stubble with fertilizer, and stubble without fertilizer areas. The fields with stubble burning emitted the highest emission of methane (75,771.29 ton) followed by stubble burning with manure (22,251.08 ton), stubble burning with fertilizer (13,213.27 ton), and stubble burning with fertilizer application areas (3,222.22 ton). The total emission of methane from rice field in Cambodia for the years 2005-2006 was approximately 342,649.26 ton (342.65 Gg) in the first crop season and 36,838.88 ton (36.84 Gg) in the second crop season. During the first crop season in the years 2005-2006, Battambang province emitted the highest amount of CH(4) (38,764.48 ton) and, in the second crop season during the years 2005-2006, the highest emission (8,262.34 ton) was found in Takeo province (8,262.34 ton). Nitrous oxide emission was between 2.70 and 1,047.92 ton in the first crop season and it ranged from 0 to 244.90 ton in the second crop season. Total nitrous oxide emission from paddy rice field was estimated to be 9,026.28 ton in the first crop season and 1,091.93 ton in the second crop season. Larger area under cultivation is responsible for higher emission of methane and nitrous oxide. Total emission of nitrous oxide by using IPCC default emission coefficient was approximately 2,328.85 ton. The total global warming potential of Cambodian paddy rice soil is 11,723,217.03 ton (11,723 Gg

    Objective: To compare the safety and efficacy of two compounds of dihydroartemisinin (DHA) Artekin and Artekin (T) in the treatment of uncomplicated falciparum malaria. Methods: The regimen of 8-tablet for 2 days of Artekin and Artekin (T) were applied to 100 patients with uncomplicated falciparum malaria, who were randomly divided into two groups. Each group contained 50 cases. The cure rate, the mean parasites clearance time, the mean fever clearance and side-effects were observed to assess the safety and efficacy of the compounds used. Results: The mean parasites clearance time was 31.7±9.0 hours in the Artekin group and 32.8±8.8 hours in Artekin (T) group respectively;the mean fever clearance time was 12.7±7.2 hours in Artekin group and 16.5±7.9 hours in Artekin (T) group; there were no recrudescence case in both groups within the 28 days of follow-up,the cure rates in Artekin group and Artekin (T) groups were 100%. It indicated that the tolerability of both compounds were very good, the side-effects such as nausea, abdominal pain were mild and self-limited. Conclusion: The study preliminarily indicated that the DHA and PQ compounds were of high efficacy, rapid acting and low toxicity. Artekin is very promising as a cheap, simple, effective treatment for multi-resistance malaria in Cambodia.

    Full Text Available We report on outcomes and lessons learned from a 15-month initiative in Cambodia's Tonle Sap Lake. Employing the appreciation-influence-control (AIC model of participatory stakeholder engagement, the initiative built shared understanding of the sources of vulnerability in fisheries livelihoods and catalyzed collective action to support resilience in this valuable and productive social-ecological system. Outcomes include the transfer of a large, commercial fishing concession to community access, and resolution of a boundary dispute involving community fishery organizations in neighboring provinces. Motivated by these successes, the main national grassroots network representing fishing communities also modified its internal governance and strategy of engagement to emphasize constructive links with government and the formal NGO sector. The AIC approach, we argue, provides an effective route to enable collective action in ways that strengthen dialogue and collaboration across scales, fostering the conditions for local-level transformations that can contribute to improvement in governance. We conclude with a discussion of the broader implications for resilience practice.

    Low-cost options for the treatment of drinking water at the household level are being explored by the Cambodian government and non-governmental organizations (NGOs) working in Cambodia, where many lack access to improved drinking water sources and diarrhoeal diseases are the most prevalent cause of death in children under 5 years of age. The ceramic water purifier (CWP), a locally produced, low-cost ceramic filter, is now being implemented by several NGOs, and an estimated 100,000+households in the country now use them for drinking water treatment. Two candidate filters were tested for the reduction of bacterial and viral surrogates for waterborne pathogens using representative Cambodian drinking water sources (rainwater and surface water) spiked with Escherichia coli and bacteriophage MS2. Results indicate that filters were capable of reducing key microbes in the laboratory with mean reductions of E. coli of approximately 99% and mean reduction of bacteriophages of 90-99% over >600 litres throughput. Increased effectiveness was not observed in filters with an AgNO3 amendment. At under US$10 per filter, locally produced ceramic filters may be a promising option for drinking water treatment and safe storage at the household level.

    Full Text Available Most of the land reforms of recent decades have followed an approach of “formalization and capitalization” of individual land titles (de Soto 2000. However, within the privatization agenda, benefits of unimproved land (such as land rents and value capture are reaped privately by well-organized actors, whereas the costs of valorization (e.g., infrastructure or opportunity costs of land use changes are shifted onto poorly organized groups. Consequences of capitalization and formalization include rent seeking and land grabbing. In developing countries, formal law often transpires to work in favor of the winners of the titling process and is opposed by the customary rights of the losers. This causes a lack of general acknowledgement of formalized law (which is made responsible for deprivation of livelihoods of vulnerable groups and often leads to a clash of formal and customary norms. Countries may fall into a state of de facto anarchy and “de facto open access”. Encroachment and destruction of natural resources may spread. A reframing of development policy is necessary in order to fight these aberrations. Examples and evidence are provided from Cambodia, which has many features in common with other countries in Asia and Sub-Saharan Africa in this respect.

  20. The Linked Response: Lessons Emerging from Integration of HIV and Reproductive Health Services in Cambodia

    2013-01-01

    Full Text Available A qualitative assessment was made of service provider and user perceptions of the quality of integrated reproductive health services established through a pilot intervention in Cambodia. The intervention aimed to promote pregnant women's HIV testing and general utilization of reproductive health facilities as well as improve the follow-up of HIV-positive women and exposed infants through strengthened referral and operational linkages amongst health facilities/services and community-based support interventions for PLHIV. The study was conducted in one operational district where the intervention was piloted and for comparative purposes in a district where integrated services had yet to be implemented. Service providers in the pilot district reported improved collaboration and coordination of services, more effective referral, and the positive impact of improved proximity of HIV testing through integrated local level facilities. Community-based support teams for PLHIV embraced their expanded role, were valued by families receiving their assistance, and were understood to have had an important role in referral, PMTCT follow-up and countering PLHIV stigmatization; findings which underscore the potential role of community support in integrated service provision. Challenges identified included stigmatization of PLHIV by health staff at district hospital level and a lack of confidence amongst non-specialized health staff when managing deliveries by HIV-positive women, partly due to fear of HIV transmission.

    This paper presents an overview of municipal solid waste management (MSWM) for both technical and regulatory arrangements in the municipality of Phnom Penh (MPP), Cambodia. Problems with the current MSWM are identified, and challenges and recommendations for future improvement are also given in this paper. MPP is a small city with a total area of approximately 374 km(2) and an urban population of about 1.3 million in 2008. For the last 14 years, average annual municipal solid waste (MSW) generated in MPP has increased rapidly from 0.136 million tons in 1995 to 0.361 million tons in 2008. The gross generation rate of MSW per capita was 0.74 kg day(-1). However, the per capita household waste generation was 0.487 kg day(- 1). At 63.3%, food waste is the predominant portion of generated waste, followed by plastics (15.5%), grass and wood (6.8%), and paper and cardboard (6.4%). The remaining waste, including metals, glass, rubber/leather, textiles, and ceramic/ stone, accounted for less than 3%. Waste recycling through informal sectors is very active; recycled waste accounted for about 9.3% of all waste generated in 2003. Currently, the overall technical arrangement, including storage and discharge, collection and transport, and disposal, is still in poor condition, which leads to environmental and health risks. These problems should be solved by improving legislation, environmental education, solid waste management facilities, and management of the waste scavengers.

    Full Text Available Global coverage and scale up of interventions to reduce newborn mortality remains low, though progress has been achieved in improving newborn survival in many low-income settings. An important factor in the success of newborn health interventions, and moving to scale, is appropriate design of community-based programs and strategies for local implementation. We report the results of formative research undertaken to inform the design of a newborn health intervention in Cambodia. Information was gathered on newborn care practices over a period of three months using multiple qualitative methods of data collection in the primary health facility and home setting. Analysis of the data indicated important gaps, both at home and facility level, between recommended newborn care practices and those typical in the study area. The results of this formative research have informed strategies for behavior change and improving referral of sick infants in the subsequent implementation study. Collection and dissemination of data on newborn care practices from settings such as these can contribute to efforts to advance survival, growth and development of newborns for intervention research, and for future newborn health programming.

    Pygidiopsis cambodiensis n. sp. is described based on adult flukes recovered from Syrian golden hamsters experimentally infected with metacercariae from mullets (Liza macrolepis) purchased at a local fish market in Phnom Penh, Cambodia. The specimens were examined by light and scanning electron microscopy. Among the 13 species so far assigned to Pygidiopsis, the new species belongs to the summa-type (including Pygidiopsis pelecani, Pygidiopsis phalacrocoracis, Pygidiopsis piclaumoreli, Pygidiopsis plana, and Pygidiopsis summa) which lack circumoral spines and have vitelline follicles extending posteriorly from the level of the ovary some distance into the post-testicular space and the uterus not exceeding the acetabulum anteriorly. The new species differs from the other five species of the summa-type particularly in the morphology of the ventrogenital complex, including the genital sac, gonotyl, and gonotyl spines (= rodlets). The genital sac is well developed, sucker-like, slightly larger than the ventral sucker, muscular, and equipped with two gonotyls on the ventral side of the sac. Gonotyls are protruding pad-like, and the number of rodlets on the left gonotyl is four to five and that on the right gonotyl is 10-11 in two rows. This is the fifth Pygidiopsis species reported in Asia, following P. summa (Japan, Korea, and Vietnam), P. phalacrocorasis (Japan), P. pelecani (China), and Pygidiopsis marivillai (Philippines).

    There are limited data on osteoarticular infections from resource-limited settings in Asia. A retrospective study of patients presenting to the Angkor Hospital for Children, Cambodia, January 2007–July 2011, identified 81 cases (28% monoarticular septic arthritis, 51% single-limb osteomyelitis and 15% multisite infections). The incidence was 13.8/100 000 hospital attendances. The median age was 7.3 years, with a male/female ratio of 1.9:1; 35% presented within 5 days of symptom onset (median 7 days). Staphylococcus aureus was cultured in 29 (36%) cases (52% of culture-positive cases); one isolate was methicillin-resistant (MRSA). Median duration of antimicrobial treatment was 29 days (interquartile range 21–43); rates of surgical intervention were 96%, and 46% of children had sequelae, with one fatality. In this setting osteoarticular infections are relatively common with high rates of surgical intervention and sequelae. Staphylococcus aureus is the commonest culturable cause, but methicillin-resistant S. aureus is not a major problem, unlike in other Asian centers. PMID:22977206

    The study assessed the trends of nutritional status of children under age five in Cambodia over four DHS surveys from 2000 to 2014 and the contribution of socioeconomic and demographic factors to its changes. Undernutrition was a public health problem in all surveys. Despite consistent improvement over the years, stunting still affected 32.5% of children in 2014. Wasting prevalence did not improve since 2005 and affected 9.6% of children under five in 2014. Low wealth and mother education; and rural residence contributed to undernutrition. In 2014; wealth status was the main socioeconomic factor associated with undernutrition and the nutritional status of children was strongly related to that of their mothers. Anemia prevalence was high and after a decrease between 2000 and 2005 remained at 45%. The prevalence of overweight was less than 10% and did not change over the years despite an increasing trend in the richest households of urban areas. Persistent inequalities in child undernutrition call for action, giving priority to the most vulnerable households to ensure availability and access to nutrient-rich foods for women and children through nutrition-sensitive and nutrition-specific programs. The recent increase of overweight in the richest populations must also be considered in Cambodian health policies.

    Information on Strongyloides stercoralis re-infection after ivermectin treatment is scarce in S. stercoralis endemic countries. In semi-rural Cambodia, we determined S. stercoralis infection and re-infection rates among schoolchildren, two years after ivermectin treatment (2×100 μg/kg PO, 24 h apart). The study was conducted among 484 children from four primary schools in semi-rural villages in Kandal province from 2009 to 2011, using Koga agar plate culture and the Baermann method on two stool samples per child. Complete data were available for 302 participants. We observed infections in 24.2% and 22.5% of the children at baseline and at follow-up, respectively. At baseline, 73 children were treated for S. stercoralis infection. At follow-up, one-third of those treated for S. stercoralis infection had been reinfected, while 19.6% of the 229 healthy children (at baseline) had been newly infected with S. stercoralis. Possession of shoes and defecation in toilet were negatively associated with S. stercoralis infection at follow-up. Infection and re-infection rates of S. stercoralis among schoolchildren are considerably high. However, 68.5% of infected children remained free of infection for at least two years. A large-scale cohort study is required to understand age-specific infection and re-infection dynamics in endemic countries.

    Full Text Available Background: The Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA checklist is used worldwide to drive quality improvement in laboratories in developing countries and to assess the effectiveness of interventions such as the Strengthening Laboratory Management Toward Accreditation (SLMTA programme. However, the paperbased format of the checklist makes administration cumbersome and limits timely analysis and communication of results.Development of e-Tool: In early 2012, the SLMTA team in Vietnam developed an electronic SLIPTA checklist tool. The e-Tool was pilot tested in Vietnam in mid-2012 and revised. It was used during SLMTA implementation in Vietnam and Cambodia in 2012 and 2013 and further revised based on auditors’ feedback about usability.Outcomes: The SLIPTA e-Tool enabled rapid turn-around of audit results, reduced workload and language barriers and facilitated analysis of national results. Benefits of the e-Tool will be magnified with in-country scale-up of laboratory quality improvement efforts and potential expansion to other countries.

    This study investigated the type of environmental habitat that may explain the infection of 1176 individuals from 17 rodent species by Bartonella species in seven sites in Cambodia, Lao PDR, and Thailand. No effects of host sex and host maturity on the level of individual infection by all Bartonella spp., but significant effects of locality, season, and host species were observed. The patterns differed when investigating the three more prevalent Bartonella species. For B. rattimassiliensis, season and habitat appeared to be significant factors explaining host infection, with higher levels of infection in wet season and lower levels of infection in rain-fed field, dry field, and human settlement habitats compared to forest habitat. The infection by B. queenslandensis was found to vary, although not significantly, with season and locality, and Bartonella n. sp. (a species mostly associated with Mus spp.) was found to be more prevalent in the wet season and dry field habitat compared to forest habitat. We discuss these results in relation to rodent habitat specificity.

    Full Text Available The function of the ritual is to assert a transcendental power over everyday experience and rituals therefore tend to be formalized, repetitive and conservative events. The purpose of this paper is to show the importance for ritual studies of ritualised strategies for the negotiation of power and influence. Here, research on a spirit possession cult among the Muslim Cham in Cambodia will serve as an empirical basis for a discussion of the open-ended and unbounded features of ritual in contemporary society, since the performances of this cult may be seen both as a kind of "state ritual" and as exorcism. Through the cult, the Cham tend to take refuge in their memories of the distant past rather than in their more immediate memories of terror and political violence, during the civil war and the Khmer Rouge regime. Rephrased as songs of the spirits, the present and the past intermingle in narrating the difficulties, the conflicts and the struggle in the world of the spirits who live next to, and mingle in, the world of ordinary human beings.

The results of this formative research have informed strategies for behavior change and improving referral of sick infants in the subsequent implementation study. Collection and dissemination of data on newborn care practices from settings such as these can contribute to efforts to advance survival, growth and development of newborns for intervention research, and for future newborn health programming.

    We examined condom-use negotiation strategies and condom use among 81 female sex workers (FSWs) in Phnom Penh, Cambodia. Percentages of FSWs who did not negotiate condom use or could not describe a negotiation strategy with native clients, foreign clients, and non-paying partners were 15.0, 29.0 and 67.6 %, respectively. The most common negotiation strategy used was "provision of risk information" for native clients (43.8 %) and non-paying partners (26.5 %), and "direct request" for foreign clients (39.5 %). About half could not describe more than one negotiation strategy. Consistent condom use was high with native clients (98.8 %), yet comparatively lower with foreign clients (86.9 %) and non-paying partners (26.5 %). FSWs who did not negotiate or did not know how to negotiate condom use were less likely to report condom use with non-paying regular partners. Future interventions should enhance condom negotiation strategies between FSWs and all partner types.

    The effectiveness of point-of-use water treatment may be limited by declining use over time, particularly when water treatment is introduced via targeted intervention programmes. In order to evaluate the long-term uptake and use of locally produced ceramic water filters in rural Cambodia, we visited households that had received filters as part of NGO-subsidized distribution programmes over a 4 year period from 2002 to 2006. Of the more than 2,000 filters distributed, we visited 506 randomly selected households in 13 villages spanning three provinces to assess filter time in use and to collect data on factors potentially correlated with long-term use. Results indicate that filter use declined at the rate of approximately 2% per month after implementation, largely owing to breakages, and that, controlling for time since implementation, continued filter use over time was most closely positively associated with: related water, sanitation and hygiene practices in the home; cash investment in the technology by the household; and use of surface water as a primary drinking water source.

  13. Poverty, economic growth, deprivation, and water: the cases of Cambodia and Vietnam.

    Poverty reduction decorates all development agendas, but the complexity of the poverty issue is too often hidden behind simplistic indicators and development goals. Here, a closer look is taken at the concepts of "deprivation" and "vulnerability" as outcomes of poverty. Deprivation leads typically to social exclusion and marginalization; such groups are particularly weak in getting themselves out of poverty by "self-help," and economic growth does not trickle down to these people. When looking at the connections between poverty reduction and economic growth, special emphasis should be put on the differences between modern and more traditional sectors: development of the modern sector should not marginalize and exclude those dependent on more traditional livelihoods. Two case studies--The Tonle Sap area, Cambodia, and the Mekong Delta, Vietnam--reveal that investment in education, empowerment of small-scale entrepreneurship and other means of microeconomic environment, along with good governance, infrastructure, and income distribution can ensure that economic growth includes the poorer echelons of society.

    Full Text Available The study assessed the trends of nutritional status of children under age five in Cambodia over four DHS surveys from 2000 to 2014 and the contribution of socioeconomic and demographic factors to its changes. Undernutrition was a public health problem in all surveys. Despite consistent improvement over the years, stunting still affected 32.5% of children in 2014. Wasting prevalence did not improve since 2005 and affected 9.6% of children under five in 2014. Low wealth and mother education; and rural residence contributed to undernutrition. In 2014; wealth status was the main socioeconomic factor associated with undernutrition and the nutritional status of children was strongly related to that of their mothers. Anemia prevalence was high and after a decrease between 2000 and 2005 remained at 45%. The prevalence of overweight was less than 10% and did not change over the years despite an increasing trend in the richest households of urban areas. Persistent inequalities in child undernutrition call for action, giving priority to the most vulnerable households to ensure availability and access to nutrient-rich foods for women and children through nutrition-sensitive and nutrition-specific programs. The recent increase of overweight in the richest populations must also be considered in Cambodian health policies.

    Full Text Available Two species of otters are found along Tropeang Roung River, the smooth-coated otter (Lutrogale perspecillata and the hairy-nosed otter (Lutra sumatrana. The distribution of these species was studied along a stretch of the Tropeang Roung River in Koh Kong province, Cambodia, between May and June 2009. Their main habitat appears to be both small and big estuary surrounded by Melaleuca, Mangrove and evergreen forest with shoreline vegetation followed by sand (24%, clay (13%, rocky (10% and bank with vegetation (53%, where is rich of food sources, particularly fish. The sprainting sites were found more under open sky then canopy cover, and situated their spraint in average of 4.33 m from water edge and 2.73 m of water depth. Diet compositions in spraint consisted of fish 64%, frog 5%, crab 2%, shrimp 1% and unidentified debris 28%. The study revealed that the distribution of otters along the river has diminished. Hunting for skin to trade, traditional medicine, meat and habitat disturbance such as sand mining and fishing activities might be putting pressure on the population. Conservation measures such as monitoring of the otter population and interviewing locals should be done regularly and restrictions on sand mining, oil spills from shipping and snaring should be imposed along Tropeang Roung River.

  16. Using Social Network Analysis to Evaluate Health-Related Adaptation Decision-Making in Cambodia

    Full Text Available Climate change adaptation in the health sector requires decisions across sectors, levels of government, and organisations. The networks that link these different institutions, and the relationships among people within these networks, are therefore critical influences on the nature of adaptive responses to climate change in the health sector. This study uses social network research to identify key organisational players engaged in developing health-related adaptation activities in Cambodia. It finds that strong partnerships are reported as developing across sectors and different types of organisations in relation to the health risks from climate change. Government ministries are influential organisations, whereas donors, development banks and non-government organisations do not appear to be as influential in the development of adaptation policy in the health sector. Finally, the study highlights the importance of informal partnerships (or ‘shadow networks’ in the context of climate change adaptation policy and activities. The health governance ‘map’ in relation to health and climate change adaptation that is developed in this paper is a novel way of identifying organisations that are perceived as key agents in the decision-making process, and it holds substantial benefits for both understanding and intervening in a broad range of climate change-related policy problems where collaboration is paramount for successful outcomes.

This study found that the majority of care providers in both settings perceived poverty and violence as significant causes and consequences of human suffering and, at the same time, felt ill-equipped in addressing these issues and related problems. Other issues that hindered these healers in providing care included: limited government/institutional support; lack of training; materialresources and funding. Study findings point to a new framework fordeveloping effective interventions and the need for further emphasison supporting care providers in their work, and most specifically, inidentifying and responding to poverty and violence.

    Full Text Available Abstract Background Population movements along the Thailand-Cambodia border, particularly among highly mobile and hard-to-access migrant groups from Cambodia and Myanmar, are assumed to play a key role in the spread of artemisinin resistance. Data on treatment-seeking behaviours, knowledge and perceptions about malaria, and use of preventive measures is lacking as characteristics of this population prevent them from being represented in routine surveillance and the lack of a sampling frame makes reliable surveys challenging. Methods A survey of migrant populations from Cambodia and Myanmar was implemented in five selected rural locations in Thailand along the Thai-Cambodian border using respondent driven sampling (RDS to determine demographic characteristics of the population, migratory patterns, knowledge about malaria, and health-care -seeking behaviours. Results The majority of migrants from Myanmar are long-term residents (98% with no plans to move back to Myanmar, understand spoken Thai (77% and can therefore benefit from health messages in Thai, have Thai health insurance (99% and accessed public health services in Thailand (63% for their last illness. In comparison, the majority of Cambodian migrants are short-term (72%. Of the short-term Cambodian migrants, 92% work in agriculture, 18% speak Thai, 3.4% have Thai health insurance, and the majority returned to Cambodia for treatment (45%, self-treated (11%, or did not seek treatment for their last illness (27%. Conclusion Most highly mobile migrants along the Thai-Cambodia border are not accessing health messages or health treatment in Thailand, increasing their risk of malaria and facilitating the spread of potentially resistant Plasmodium falciparum as they return to Cambodia to seek treatment. Reaching out to highly mobile migrants with health messaging they can understand and malaria diagnosis and treatment services they can access is imperative in the effort to contain the spread of

    Full Text Available Background and objective: There are no recent data on the prevalence of drug-resistant tuberculosis (DR TB in Cambodia. We aim to describe TB drug resistance amongst adults with pulmonary and extra-pulmonary TB and human immunodeficiency virus (HIV co-infection in a national referral hospital in Phnom Penh, Cambodia. Design: Between 22 November 2007 and 30 November 2009, clinical specimens from HIV-infected patients suspected of having TB underwent routine microscopy, Mycobacterium tuberculosis culture, and drug susceptibility testing. Laboratory and clinical data were collected for patients with positive M. tuberculosis cultures. Results: M. tuberculosis was cultured from 236 HIV-infected patients. Resistance to any first-line TB drug occurred in 34.7% of patients; 8.1% had multidrug resistant tuberculosis (MDR TB. The proportion of MDR TB amongst new patients and previously treated patients was 3.7 and 28.9%, respectively (p<0.001. The diagnosis of MDR TB was made after death in 15.8% of patients; in total 26.3% of patients with MDR TB died. The diagnosis of TB was established by culture of extra-pulmonary specimens in 23.6% of cases. Conclusions: There is significant resistance to first-line TB drugs amongst new and previously treated TB–HIV co-infected patients in Phnom Penh. These data suggest that the prevalence of DR TB in Cambodia may be higher than previously recognised, particularly amongst HIV-infected patients. Additional prevalence studies are needed. This study also illustrates the feasibility and utility of analysis of non-respiratory specimens in the diagnosis of TB, even in low-resource settings, and suggests that extra-pulmonary specimens should be included in TB diagnostic algorithms.

    This commentary offers insight into how to best address barriers that may hinder the translation of malaria research findings into policy. It also proposes viable methods of implementing these policies in Cambodia. Currently, a wide range of malaria research is being conducted by in-country stakeholders, including Cambodia's National Programme for Parasitology, Entomology and Malaria Control's (CNM), non-governmental organizations, and academic institutions. Coordinating research amongst these partners, as well as within the Ministry of Health, is a challenge. Results are rarely disseminated widely and seldom inform programme and policy decisions. CNM and its research partners have severely limited access to each other's databases. This lack of accessibility, timeliness, engagement and cooperation between CNM and its partners greatly impacts overall research efficiency in this field, and is stifling innovation both within and beyond CNM. Cambodia has set a goal to eradicate all forms of malaria by 2030. As countries approach the elimination phase, there is a greater need for sharing research-generated evidence amongst partners, in order to ensure that appropriate and impactful activities are conducted. The Cambodian Research Consortium was established to serve as a framework for partners, stakeholders and researchers to share research projects, information and results, and to promote the goals of CNM. The sharing of malaria research results will help to inform prevention, control and elimination activities in the country. It will also determine and address the country's operational research needs, and could potentially become a framework model to be used in other countries aiming to transition from malaria control to elimination.

    Full Text Available Objective: The purpose of this project was to gather epidemiological data on common diseases and medications dispensed during medical mission trips to Cambodia to shape the mobile medical clinic formulary. Methods: Data for patients seen during week-long mobile medical clinics was collected in Cambodia during Septembers 2012 to 2014. Each patient’s gender, age, weight, blood pressure, glucose, pertinent laboratory values, diagnoses, and medications dispensed were collected. Blood pressure and glucose levels were measured in patients 18 years and above. Data collected onto paper intake forms were transferred onto spreadsheets without patient identifying information and analyzed for aggregate means, common diseases, and most dispensed medications. This project received institutional review board approval. Results: A total of 1,015 patients were seen over three years. Women made up 61.4%, and the mean age was 41.8 years. The most common diagnosis was gastrointestinal disorders (22.9% that included gastroesophageal reflux disease and intestinal parasites. Next, 20.1% of patients had hypertension (BP>140/90, 18.0% had presbyopia, 15.4% had back and joint pain, followed by 8.8% with headache, including migraines. Approximately 8.4% of patients had hyperglycemia (RPG >140 mg/dl. The top five medications dispensed were acetaminophen, omeprazole, multivitamin, ibuprofen, and metformin. For hypertension, amlodipine and lisinopril were dispensed. Conclusion: Cambodia lacks systematic public health collection of epidemiological data for prevalence of diseases. Hence, investigators collected and analyzed information from week-long mobile medical clinics over three years. Proton-pump inhibitors and H. pylori lab tests were recommended for gastrointestinal disorders. Acetaminophen and ibuprofen were recommended for pain. Angiotensin-converting-enzyme inhibitors and dihydropyridine calcium channel blockers were recommended over diuretics since patients were

    Biodeterioration is a major problem for the conservation of cultural heritage materials. We provide a new and original approach to analyzing changes in patterns of colonization (Biodeterioration patterns, BPs) by biological agents responsible for the deterioration of outdoor stone materials. Here we analyzed BPs of four Khmer temples in Angkor (Cambodia) exposed to variable environmental conditions, using qualitative ecological assessments and statistical approaches. The statistical analyses supported the findings obtained with the qualitative approach. Both approaches provided additional information not otherwise available using one single method. Our results indicate that studies on biodeterioration can benefit from integrating diverse methods so that conservation efforts might become more precise and effective.

    2014-08-01

    In arsenic-affected regions of Cambodia, rural water committees and planners can choose to promote various arsenic-avoidance and/or arsenic-removal water supply systems. Each of these has different costs of providing water, subsequently born by the consumer in order to be sustainable. On a volumetric basis ($/m3-yr) and of the arsenic-avoidance options considered, small-scale public water supply - e.g., treated water provided to a central tap stand - is the most expensive option on a life-cycle cost basis. Rainwater harvesting, protected hand dug wells, and vendor-supplied water are the cheapest with a normalized present worth value, ranging from $2 to $10 per cubic meter per year of water delivered. Subsidization of capital costs is needed to make even these options affordable to the lowest (Q5) quintile. The range of arsenic-removal systems considered here, using adsorptive media, is competitive with large-scale public water supply and deep tube well systems. Both community level and household-scale systems are in a range that is affordable to the Q4 quintile, though more research and field trials are needed. At a target cost of $5.00/m3, arsenic removal systems will compete with the OpEx costs for most of the arsenic-safe water systems that are currently available. The life-cycle cost approach is a valuable method for comparing alternatives and for assessing current water supply practices as these relate to equity and the ability to pay.

    The emergence and spread of Highly Pathogenic Avian Influenza H5N1 has caused substantial poultry-related economic losses and public health concerns in relation to a potential pandemic. While biosecurity measures for commercial poultry industry are of the highest standards, these measures are difficult to implement and often unaffordable for backyard poultry farming, particularly in tropical and low-income settings. We designed a feasible biosecurity intervention to improve flock hygiene in Cambodia, - based on community hygiene, cleaning of poultry flock areas and human and poultry movement control. We conducted a cluster randomized and controlled intervention trial in 18 villages in Takeo province to evaluate improvements in biosecurity-related knowledge and practices. The intervention relied on community involvement and community education using special information dissemination tools. We trained village teams (VT) to assist villagers in implementing the intervention using a cascade training approach, in which a few individuals were trained, who in turn trained a larger group of people. During the 14 month follow up, we conducted observational and interview-based surveys (baseline vs. final surveys, VT supervision visits, monitoring surveys) to assess VTs' motivation, intervention messages dissemination and the implementation of recommended measures. Most of villagers (95%, confidence interval: 87.8-100.0%) in intervention villages received general information about how to raise poultry. Farmers in intervention villages reported to have made more changes (≥1 biosecurity related practice during the study period) compared with that of control villages (70.0% (260/372) vs. 22.6% (85/377), p valuebiosecurity-related practices in intervention villages, overall scores increased significantly (pbiosecurity practices in the community. However, further follow-ups are needed to assess whether practices-related changes persist over a longer period of time.

  8. Entrenched geographical and socioeconomic disparities in child mortality: trends in absolute and relative inequalities in Cambodia.

    Eliana Jimenez-Soto

    Full Text Available BACKGROUND: Cambodia has made considerable improvements in mortality rates for children under the age of five and neonates. These improvements may, however, mask considerable disparities between subnational populations. In this paper, we examine the extent of the country's child mortality inequalities. METHODS: Mortality rates for children under-five and neonates were directly estimated using the 2000, 2005 and 2010 waves of the Cambodian Demographic Health Survey. Disparities were measured on both absolute and relative scales using rate differences and ratios, and where applicable, slope and relative indices of inequality by levels of rural/urban location, regions and household wealth. FINDINGS: Since 2000, considerable reductions in under-five and to a lesser extent in neonatal mortality rates have been observed. This mortality decline has, however, been accompanied by an increase in relative inequality in both rates of child mortality for geography-related stratifying markers. For absolute inequality amongst regions, most trends are increasing, particularly for neonatal mortality, but are not statistically significant. The only exception to this general pattern is the statistically significant positive trend in absolute inequality for under-five mortality in the Coastal region. For wealth, some evidence for increases in both relative and absolute inequality for neonates is observed. CONCLUSION: Despite considerable gains in reducing under-five and neonatal mortality at a national level, entrenched and increased geographical and wealth-based inequality in mortality, at least on a relative scale, remain. As expected, national progress seems to be associated with the period of political and macroeconomic stability that started in the early 2000s. However, issues of quality of care and potential non-inclusive economic growth might explain remaining disparities, particularly across wealth and geography markers.

  9. The Establishment of the National Language in Twentieth-Century Cambodia: Debates on Orthography and Coinage

    2015-04-01

    Full Text Available This paper explores the process in which an ethnic Khmer language became the national one in Cambodia, through a discussion of activities and debates concerned with orthography and coinage of the modern vocabulary. The committee for editing a Khmer dictionary established in 1915 consisted of both members who insisted on an etymological style of orthography and those who favored a phonemic style. A Buddhist monk Chuon Nath took the initiative from 1926 on and published the first Khmer-language dictionary in 1938. After the perfection of orthography based on an etymological style in the dictionary, the “Cultural Committee” began to create new vocabularies in 1947. Here again Chuon Nath assumed leadership with his best friend Huot Tat. The Cultural Committee rejected Sanskrit-originated words created in Siam and preferred the Pali language as elements of the modern vocabulary. Keng Vannsak objected strongly to these activities and claimed that the Khmer language had to exclude as many Sanskrit/Pali-originated words as possible in order to expand primary education. In 1967 the National Assembly recognized Khmer as the teaching language in schools, and a new educational magazine Khemarayeanakam [Khmerization] was launched. In the process of editing this magazine, the followers of Keng Vannsak presented another way of coinage that they alleged was much easier, and advocated a new orthography. Even after the civil war, their new orthography continued to be used in education and media. In 2009, however, orthography recurred to the dictionary. Through a study of the vicissitudes of language policies, we can understand the formation and development of Cambodian cultural nationalism. By the early 1960s, Buddhist monks were attempting to differentiate Cambodian modern vocabulary from Thai. Thereafter advocates of Khmerization, who no longer learned the Thai language, aimed at the “purification” and “simplification” of the Khmer language.

    Disaster monitoring systems can provide near real time estimates of population and infrastructure affected by sudden onset natural hazards. This information is useful to decision makers allocating lifesaving resources following disaster events. Floods are the world's most common and devastating disasters (UN, 2004; Doocy et al., 2013), and are particularly frequent and severe in the developing countries of Southeast Asia (Long and Trong, 2001; Jonkman, 2005; Kahn, 2005; Stromberg, 2007; Kirsch et al., 2012). Climate change, a strong regional monsoon, and widespread hydropower construction contribute to a complex and unpredictable regional hydrodynamic regime. As such, there is a critical need for novel techniques to assess flood impacts to population and infrastructure with haste during and following flood events in order to enable governments and agencies to optimize response efforts following disasters. Here, we build on methods to determine regional flood extent in near real time and develop systems that automatically quantify the socioeconomic impacts of flooding in Cambodia. Software developed on cloud based, distributed processing Geographic Information Systems (GIS) is used to demonstrate spatial and numerical estimates of population, households, roadways, schools, hospitals, airports, agriculture and fish catch affected by severe monsoon flooding occurring in the Cambodian portion of Lower Mekong River Basin in 2011. Results show modest agreement with government and agency estimates. Maps and statistics generated from the system are intended to complement on the ground efforts and bridge information gaps to decision makers. The system is open source, flexible, and can be applied to other disasters (e.g. earthquakes, droughts, landslides) in various geographic regions.

  11. Vegetation and vascular flora of the Mekong River, Kratie and Steung Treng Provinces, Cambodia

    2009-04-01

    Full Text Available A preliminary and detailed botanical survey of the islands in the Mekong River between Kratie and Steung Treng was done. This area includes the most biologically intact and threatened riparian and terrestrial ecosystems along the river in Cambodia. The vegetation includes six riverine zones and four terrestrial facies. Riverine habitats are mostly intact while the terrestrial vegetation ranges from destroyed to degraded. Effective conservation measures are required to stop further habitat destruction and loss of biodiversity. One new species, 23 records for the Cambodian flora, and a total of 690 species were collected. Detailed descriptions of all habitats, a database, and photographs are included. Increased exploitative human settlement in the area has caused drastic environmental changes with extensive deforestation and hunting. The forests are grazed, burned, logged, and often cleared for agricultural use without effective control. Sustainable management and scientifically acceptable development must be implemented before the area is totally ruined. Properly conceived reforestation is urgently required as well as a conservation education project aimed directly at the people living in the area. Unless effective restraints are implemented the area will become biologically destitute and will not be able to provide the natural resources that people require--in short, the area will become uninhabitable. Restoration of degraded or destroyed places will be impossible or far more difficult than conservation and intelligent management of presently endangered places. The potential for profitable eco-tourism should also be considered since tourists will certainly want to visit natural ecosystems on some of the islands. Only if local people are directly involved in eco-tourism and understand the necessity of conservation can this activity be successful.

    Full Text Available Architecture represents key evidence of dynastic practice and change in the archaeological world. Chronologies for many important buildings and sequences, including the iconic temples of medieval Angkor in Cambodia, are based solely on indirect associations from inscriptions and architectural styles. The Baphuon temple, one of the last major buildings in Angkor without textual or scientifically-derived chronological evidence, is crucial both for the context and date of its construction and the period when its western façade was modified into a unique, gigantic Reclining Buddha. Its construction was part of a major dynastic change and florescence of the Hindu-Mahayana Buddhist state and the modification is the key evidence of Theravada Buddhist power after Angkor's decline in the 15th century. Using a newly-developed approach based on AMS radiocarbon dating to directly date four iron crampons integrated into the structure we present the first direct evidence for the history of the Baphuon. Comprehensive study of ferrous elements shows that both construction and modification were critically earlier than expected. The Baphuon can now be considered as the major temple associated with the imperial reformations and territorial consolidation of Suryavarman I (1010-1050 AD for whom no previous building to legitimize his reign could be identified. The Theravada Buddhist modification is a hundred years prior to the conventional 16th century estimation and is not associated with renewed use of Angkor. Instead it relates to the enigmatic Ayutthayan occupation of Angkor in the 1430s and 40s during a major period of climatic instability. Accurately dating iron with relatively low carbon content is a decisive step to test long-standing assumptions about architectural histories and political processes for states that incorporated iron into buildings (e.g., Ancient Greece, medieval India. Furthermore, this new approach has the potential to revise chronologies

    The aim of this study was to explore the prevalence and relationship of anticipated chronic illness stigma among patients diagnosed with a variety of chronic diseases in three Southeast Asian countries (Cambodia, Myanmar and Vietnam). A cross-sectional survey was conducted in 4,803 adult chronic disease patients (mean age 49.3 years; SD=16.5) recruited systematically from health facilities. Overall, the results indicate that 20.7% of patients reported that for any of the 12 stigma items, they anticipated they were likely or very likely to experience chronic disease stigma. A multivariate analysis of sociodemographics revealed the following were associated with anticipated chronic disease stigma: older versus younger age, OR (odds ratio) = 0.71; 95% Confidence Interval (CI) [0.58, 0.87]; higher versus lower education, OR = 2.23; 95% CI [1.81, 2.75]; origin from Myanmar or Vietnam, being single, divorced or widowed, rural residence, and health status (having three or more chronic conditions versus having one chronic condition), OR = 1.93; 95% CI [1.58, 2.35]; lower versus higher quality of life, OR = 0.73; 95% CI [0.63, 0.85]); health risk behavior (physical inactivity, poor diet, current smoking, and problem drinking) and low versus medium or high medication adherence (OR = 0.69; 95% CI [0.55,0.86]). This study demonstrated the possible consequences of anticipated stigma on the health and behavior of people living with chronic diseases, and several factors for chronic disease stigma were identified that can help guide interventions to reduce chronic illness stigma in this population.

    The Siamese crocodile (Crocodylus siamensis) is considered one of the least studied and most critically endangered crocodilians in the world. Although few wild populations remain, more than 700,000 C. siamensis are held on commercial crocodile farms in Southeast Asia. Despite conservation concerns, many aspects of C. siamensis life history remain poorly known, particularly with regards to its reproductive biology. We studied nesting phenology, clutch characteristics, and other aspects of C. siamensis reproductive biology on crocodile farms in Cambodia during 2000 and 2001. Oviposition among captive crocodiles began in February and continued into early June. The mean (±1 SD) oviposition date based on pooled data from 2000 and 2001 was 5 April ± 24 days. Mean oviposition date differed significantly between 2000 and 2001, possibly as a result of annual variability among nesting cues. The mean incubation period was 72 ± 3 days and eggs hatched from 5 May to 18 August. Mean clutch size (25.0 ± 8.8 eggs; n = 183) differed significantly between years, possibly resulting from the >2.5-fold increase in sample size during 2001. There was no correlation between clutch size and oviposition date during either 2000 or 2001. A single female produced two clutches during 2001, complimenting previous reports of double-clutching among C. siamensis. The mean length and width of 515 eggs were 78.2 ± 4.9 and 48.1 ± 2.5 mm, respectively; mean egg mass was 90.8 ± 16.5 g (n = 471). One unpipped egg contained a set of twins.

    This paper presents insight into the benefits of organic waste recycling through composting over landfill, in terms of landfill life extension, compost product, and mitigation of greenhouse gases (GHGs). Future waste generation from 2003 to 2020 was forecast, and five scenarios of organic waste recycling in the municipality of Phnom Penh (MPP), Cambodia, were carried out. Organic waste-specifically food and garden waste-was used for composting, and the remaining waste was landfilled. The recycling scenarios were set based on organic waste generated from difference sources: households, restaurants, shops, markets, schools, hotels, offices, and street sweeping. Through the five scenarios, the minimum volume reductions of waste disposal were about 56, 123, and 219 m(3) d(-1) in 2003, 2012, and 2020, respectively, whereas the maximum volume reductions in these years were about 325, 643, and 1025 m(3) d(-1). These volume reductions reflect a landfill life extension of a minimum of half a year and a maximum of about four years. Compost product could be produced at a minimum of 14, 30, and 54 tons d(-1) in 2003, 2012, and 2020, respectively, and at a maximum in those years of about 80, 158, and 252 tons d(-1). At the same time benefit is gained in compost product, GHG emissions could be reduced by a minimum of 12.8% and a maximum of 65.0% from 2003 to 2020. This means about 3.23 (minimum) and 5.79 million tons CO(2)eq (maximum) contributed to GHG mitigation. In this regard, it is strongly recommended that MPP should try to initiate an organic-waste recycling strategy in a best fit scenario.

    This report deals with the escalating challenge Cambodia faces in its agricultural sector for providing sufficient feeding to an increasing population, while also having improper soil management. Based on field visits, interviews, regular meetings, training workshops, and joint analysis it was revealed that farmers used both organic (bio-slurry) and inorganic fertilisers but were unaware of the balance needed and required doses of fertiliser. Further, it appeared that farmers have limited access to improve crop management practices, specifically to fertiliser management. In a response to the problem, the current weaknesses, and further scope of improvement of present organisational setup of slurry extension component of NBP and subsidy system have been analysed in depth. Extensive recommendations are offered on an organisational setup level (e.g. strengthen the linkage between Provincial Biogas Program Office-PBPO and Cambodian Centre for Study and Development in Agriculture-CEDAC by involving CEDAC in the planning process), subsidy (e.g. provide subsidy to attract farmers for construction of standard compost hut, boundaries and shade), planning (e.g. bottom up planning approach is suggested where a seasonal planning meeting should be organized at province by the project director involving CEDAC provincial coordinator), development of training materials (e.g. a national consultant should be hired for developing a training manual on bio-slurry systems), training (e.g. strengthen user training by increasing its number, frequency, topics), farmers participatory action research (e.g. the participatory approach should be replaced by a demonstration one), monitoring and reporting (e.g. monitoring system should be established as desk and field monitoring)

    Improved sanitation access is extremely low in rural Cambodia. Non-governmental organizations have helped build local supply side latrine markets to promote household latrine purchase and use, but households cite inability to pay as a key barrier to purchase. To examine the extent to which microfinance can be used to facilitate household investment in sanitation, we applied a two-pronged assessment: (1) to address the gap between interest in and use of microfinance, we conducted a pilot study to assess microfinance demand and feasibility of integration with a sanitation marketing program and (2) using a household survey (n = 935) at latrine sales events in two rural provinces, we assessed attitudes about microfinance and financing for sanitation. We found substantial stated intent to use a microfinance institution (MFI) loan to purchase a latrine (27%). Five percent of current owners used an MFI loan for latrine purchase. Credit officers attended 159 events, with 4761 individuals attending. Actual loan applications were low, with 4% of sales events attendees applying for a loan immediately following the event (mean = 1.7 loans per event). Ongoing coordination was challenging, requiring management commitment from the sanitation marketing program and commitment to social responsibility from the MFI. Given the importance of improving sanitation coverage and concomitant health impacts, linking functional sanitation markets to already operational finance markets has the potential to give individuals and households more financial flexibility. Further product research and better integration of private vendors and financing modalities are necessary to create a scalable microfinance option for sanitation markets.

  18. Patterns of ecosystem metabolism in the Tonle Sap Lake, Cambodia with links to capture fisheries.

    The Tonle Sap Lake in Cambodia is a dynamic flood-pulsed ecosystem that annually increases its surface area from roughly 2,500 km(2) to over 12,500 km(2) driven by seasonal flooding from the Mekong River. This flooding is thought to structure many of the critical ecological processes, including aquatic primary and secondary productivity. The lake also has a large fishery that supports the livelihoods of nearly 2 million people. We used a state-space oxygen mass balance model and continuous dissolved oxygen measurements from four locations to provide the first estimates of gross primary productivity (GPP) and ecosystem respiration (ER) for the Tonle Sap. GPP averaged 4.1±2.3 g O2 m(-3) d(-1) with minimal differences among sites. There was a negative correlation between monthly GPP and lake level (r = 0.45) and positive correlation with turbidity (r = 0.65). ER averaged 24.9±20.0 g O2 m(-3) d(-1) but had greater than six-fold variation among sites and minimal seasonal change. Repeated hypoxia was observed at most sampling sites along with persistent net heterotrophy (GPPproductivity model and predicted aquatic net primary production (aNPP) of 2.0±0.2 g C m(-2) d(-1) (2.4±0.2 million tonnes C y(-1)). Considering a range of plausible values for the total fisheries catch, we estimate that fisheries harvest is an equivalent of 7-69% of total aNPP, which is substantially larger than global average for marine and freshwater systems. This is likely due to relatively efficient carbon transfer through the food web and support of fish production from terrestrial NPP. These analyses are an important first-step in quantifying the resource pathways that support this important ecosystem.

  20. An Efficient Acoustic Density Estimation Method with Human Detectors Applied to Gibbons in Cambodia.

    Full Text Available Some animal species are hard to see but easy to hear. Standard visual methods for estimating population density for such species are often ineffective or inefficient, but methods based on passive acoustics show more promise. We develop spatially explicit capture-recapture (SECR methods for territorial vocalising species, in which humans act as an acoustic detector array. We use SECR and estimated bearing data from a single-occasion acoustic survey of a gibbon population in northeastern Cambodia to estimate the density of calling groups. The properties of the estimator are assessed using a simulation study, in which a variety of survey designs are also investigated. We then present a new form of the SECR likelihood for multi-occasion data which accounts for the stochastic availability of animals. In the context of gibbon surveys this allows model-based estimation of the proportion of groups that produce territorial vocalisations on a given day, thereby enabling the density of groups, instead of the density of calling groups, to be estimated. We illustrate the performance of this new estimator by simulation. We show that it is possible to estimate density reliably from human acoustic detections of visually cryptic species using SECR methods. For gibbon surveys we also show that incorporating observers' estimates of bearings to detected groups substantially improves estimator performance. Using the new form of the SECR likelihood we demonstrate that estimates of availability, in addition to population density and detection function parameters, can be obtained from multi-occasion data, and that the detection function parameters are not confounded with the availability parameter. This acoustic SECR method provides a means of obtaining reliable density estimates for territorial vocalising species. It is also efficient in terms of data requirements since since it only requires routine survey data. We anticipate that the low-tech field requirements will

    This study explores the therapeutic implications of including culturally adapted spiritual ceremonies in the process of testimonial therapy for torture survivors in India, Sri Lanka, Cambodia, and the Philippines. Data were collected through an action research process with Asian mental health and human rights organizations, during which the testimonial method was reconceptualized and modified to include four sessions. In the first two sessions, community workers assist survivors in the writing of their testimony, which is their narrative about the human rights violations they have suffered. In the third session, survivors participate in an honour ceremony in which they are presented with their testimony documents. In the fourth session, the community workers meet with the survivors for a reevaluation of their well-being. The honour ceremonies developed during the action research process came to employ different kinds of symbolic language at each site: human rights (India), religious/Catholic (Sri Lanka), religious/Buddhist (Cambodia), and religious/Moslem (Philippines). They all used embodied spirituality in various forms, incorporating singing, dancing, and religious purification rituals in a collective gathering. We suggest that these types of ceremonies may facilitate an individual's capacity to contain and integrate traumatic memories, promote restorative self-awareness, and engage community support. Additional research is needed to determine the method's applicability in other sociopolitical contexts governed by more Western-oriented medical traditions.

  2. The relevance of a coproductive capacity framework to climate change adaptation: investigating the health and water sectors in Cambodia

    Full Text Available Multiple active partnerships in the health and water sectors in Cambodia exist to address climate change adaptation, operating beyond typical sectoral and organizational divides. Decisions around national adaptation policy are made predominantly by the relevant lead ministry, contrasting with where funding originates from (i.e., major donors, multilaterals, United Nation agencies. Adaptation policy is thus the result of a process of coproduction by state and nonstate actors. The research we present sought to understand the relationships that exist between knowledge- and decision-makers with respect to climate change adaptation in the health and water sectors in Cambodia, and the factors that enabled or constrained these relationships. Forty-four interviews were conducted with representatives of 32 organizations. We found that coproductive relationships were most effective when there were clearly defined roles and responsibilities, coordination of technical and financial resources, and trust. The two key factors of coproductive capacity that enabled and supported these partnerships were scientific resources and governance capability. Ultimately, the roles and responsibilities given to various actors requires commensurate funding and greater consideration of existing relationships and power dynamics. The reliance on international scientific expertise also needs to be challenged so that local research capabilities can be developed and locally relevant, problem-specific information can be provided. The ongoing funding, codevelopment, and sharing of such knowledge would significantly enhance trust and cooperation.

    2015-05-01

    Full Text Available Over the last decade considerable research has been conducted on the development and the impacts of large-scale economic land concessions for plantations in Laos and Cambodia. These studies have variously illustrated that concessions frequently result in serious negative impacts on local people and the environment, often leading to dramatic transformations of landscapes and livelihoods. As important as this research has been, these studies have largely focused on the immediate impacts of the “enclosure” process associated with gaining access to land by investors. In this study we take a different approach, investigating the implications of large-scale land concessions in southern Laos and northeastern Cambodia with regard to places outside of actual concession areas, both within the countries where the concessions are located and beyond. These links have been referred to as “teleconnections” or “telecoupling”, and adopting a “telecoupling” approach allows us to focus on particular relations between land-use change in one location and land-use change elsewhere, either nearby or distant, as the result of large-scale plantation development, both during the early plantation development period, and later when plantations are productive. It also provides opportunities to engage with Land Change Science (LCS through Political Ecology (PE.

    Full Text Available A cross-sectional analysis of the Cambodia Demographic Health Surveys from 2000, 2005 and 2010 was conducted to observe the national trends in infant and young child feeding practices. The results showed that rates of exclusive breastfeeding among infants aged 0–5.9 months have increased substantially since 2000, concurrent with an increase in the rates of early initiation of breastfeeding and a reduction in the giving of pre-lacteal feeds. However, the proportion of infants being fed with breast-milk substitutes (BMS during 0–5.9 months doubled in 5 years (3.4% to 7.0% from 2000 to 2005, but then did not increase from 2005, likely due to extensive public health campaigns on exclusive breastfeeding. BMS use increased among children aged 6–23.9 months from 2000 to 2010 (4.8% to 9.3%. 26.1% of women delivering in a private clinic provided their child with breast-milk substitute at 0–5.9 months, which is five times more than women delivering in the public sector (5.1%, and the greatest increase in bottle use happened among the urban poor (5.8% to 21.7%. These findings are discussed with reference to the increased supply and marketing of BMS that is occurring in Cambodia.

    Full Text Available BACKGROUND: Adherence to effective malaria medication is extremely important in the context of Cambodia's elimination targets and drug resistance containment. Although the public sector health facilities are accessible to the local ethnic minorities of Ratanakiri province (Northeast Cambodia, their illness itineraries often lead them to private pharmacies selling "cocktails" and artemether injections, or to local diviners prescribing animal sacrifices to appease the spirits. METHODS: The research design consisted of a mixed methods study, combining qualitative (in-depth interviews and participant observation and quantitative methods (household and cross-sectional survey. RESULTS: Three broad options for malaria treatment were identified: i the public sector; ii the private sector; iii traditional treatment based on divination and ceremonial sacrifice. Treatment choice was influenced by the availability of treatment and provider, perceived side effects and efficacy of treatments, perceived etiology of symptoms, and patient-health provider encounters. Moreover, treatment paths proved to be highly flexible, changing mostly in relation to the perceived efficacy of a chosen treatment. CONCLUSIONS: Despite good availability of anti-malarial treatment in the public health sector, attendance remained low due to both structural and human behavioral factors. The common use and under-dosage of anti-malaria monotherapy in the private sector (single-dose injections, single-day drug cocktails represents a threat not only for individual case management, but also for the regional plan of drug resistance containment and malaria elimination.

    Ecological communities including tropical rainforest are rapidly changing under various disturbances caused by increasing human activities. Recently in Cambodia, illegal logging and clear-felling for agriculture have been increasing. 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 secondary dry deciduous forests. Measurements were made in 1998, 2000, 2004 and 2010, and logging, recruitment and mortality of each tree were recorded. We estimated phylogeny using rbcL and matK gene sequences and quantified phylogenetic α and β diversity. Within communities, logging decreased phylogenetic diversity, and increased overall phylogenetic clustering and terminal phylogenetic evenness. Between communities, logging increased phylogenetic similarity between evergreen and deciduous plots. On the other hand, recruitment had opposite effects both within and between communities. The observed patterns can be explained by environmental homogenization under logging. Logging is biased to particular species and larger diameter at breast height, and forest patrol has been effective in decreasing logging.

    Diagnosis of soil-transmitted helminths such as Strongyloides stercoralis and hookworms (Ancylostoma duodenale and Necator americanus) is challenging due to irregular larval and egg output in infected individuals and insensitive conventional diagnostic procedures. Sensitive novel real-time PCR assays have been developed. Our study aimed to evaluate the real-time PCR assays as a diagnostic tool for detection of Strongyloides spp. and hookworms in a random stool sample of 218 asymptomatic schoolchildren in Cambodia. Overall prevalence of 17.4% (38/218) and 34.9% (76/218) were determined by real-time PCR for S. stercoralis and hookworms, respectively. Sensitivity and specificity of S. stercoralis specific real-time PCR as compared to the combination of Baermann/Koga Agar as gold standard were 88.9% and 92.7%, respectively. For hookworm specific real-time PCR a sensitivity of 78.9% and specificity of 78.9% were calculated. Co-infections were detectable by PCR in 12.8% (28/218) of individuals. S. stercoralis real-time PCR applied in asymptomatic cases showed a lower sensitivity compared to studies undertaken with symptomatic patients with the same molecular tool, yet it proved to be a valid supplement in the diagnosis of STH infection in Cambodia.

  8. Mapping potential freshwater services, and their representation within Protected Areas (PAs, under conditions of sparse data. Pilot implementation for Cambodia

    2016-07-01

    Full Text Available Freshwater is arguably one of Earth’s most threatened natural resources, on which more than 7 billion people depend. Pressures on freshwater resources from infrastructure, resource development, agricultural pollution and deforestation are mounting, particularly in developing countries. To date, conservation responses such as Protected Areas (PAs have not typically targeted freshwater ecosystems and their services, and thus little is known about the effectiveness of these efforts in protecting them. This paper proposes and pilots an innovative freshwater services metrics framework to quantify the representation of potential freshwater services in PAs under conditions of scarce data, with a pilot application for Cambodia. Our results indicate that conservation actions have more effectively represented potential freshwater regulation services than potential freshwater provisioning services, with major rivers remaining generally unprotected. Results from the framework are then used to propose a series of context and region specific management options to improve the conservation of freshwater services in Cambodia. There is an acute need for such management options, as the country’s food security depends largely on important freshwater ecosystems such as the Tonle Sap Lake and the deep water pools systems of the Mekong River. The framework proposed can be applied in other countries or large river basins to explore the degree of representation of freshwater services within PAs systems, under conditions of sparse data.

    Malnutrition is locked in a vicious cycle of increased mortality, poor health, impaired cognitive development, slow physical growth, reduced learning capacity, inferior performance, and ultimately lower adult work performance and productivity. The consensus of global scientific evidence indicates that lowering the rates of malnutrition will be an indispensable component of any successful program to raise the quality of human capital and resources. This study used a "consequence model" to apply the coefficient risk-deficit on economic losses, established in the global scientific literature, to Cambodian health, demographic, and economic data to develop a national estimate of the value of economic losses due to malnutrition. The impact of the indicators of malnutrition analyzed represent a burden to the national economy of Cambodia estimated at 266 million USD annually (1.7% of GDP). Stunting is reducing the Cambodian economic output by more than 120 million USD, and iodine deficiency disorders alone by 57 million USD. This economic burden is too high in view of Cambodia's efforts to drive economic development. The government should rapidly expand a range of low-cost effective nutrition interventions to break the current cycle of increased mortality, poor health and ultimately lower work performance, productivity, and earnings.

    Full Text Available Developing countries face a number of challenges in their efforts to compete successfully in the new global economy. Perhaps the most critical resource needed to achieve these goals is trained human capital. While many developing countries are trying to address this need through traditional means, this may not be the most effective or efficient response. e-Learning has been suggested as an alternative approach that can overcome many of the challenges involved in reaching underserved students. But most educational institutions in developing countries are unfamiliar with e-Learning, have low levels of computer availability, access, familiarity and Internet penetration which leads to skepticism about the feasibility of this approach. In an effort to assess the potential of e-Learning in meeting the needs for developing human capital in Cambodia, this paper reports on the experience and achievements of the Provincial Business Education through the Community Information Centers (CICs project. Key findings are that e-Learning was able to successfully deliver tertiary educational opportunities to underserved provincial students, Cambodian students were able to overcome serious challenges and that female Cambodian students demonstrated superior performance in online classes. These results suggest that e-Learning is an effective alternative for delivering tertiary education in Cambodia.

    The National Biodigester Programme (NBP) Cambodia has executed a monitoring survey for her Voluntary Gold Standard (VGS) project. The VGS project is located in South-East Cambodia and covers 8 provinces. The monitoring activities are executed according to the monitoring plan in the PDD and the Gold Standard Passport, both document are approved by the DOE. The monitoring period I runs from 24-5-2009 to 31-08-2010. The survey population is 8571 biodigesters built as of 31-08-2010. The survey strategy is a stratified sampling approach, where first 12 districts were randomly selected and 120 households were randomly selected of the survey population in these 12 districts. The survey sample of 120 households is based on a confidence interval of 95% and a sampling error of 10%. The survey sample is twice as high as dictated by the used methodology in the PDD. The main findings of the monitoring survey are: (1) The project has an annual per household project emission of 0.512 tCO2 from physical leakage, incomplete combustion and wood fuel for thermal energy; (2) All the biodigester surveyed were in operation, a figure of 99% is adopted to be on the safe side; (3) The annual per household emission reductions are 4.18 tCO2; (4) The total emission reduction for the monitoring period I are 34,112 tCO2.

    Rubber (Hevea brasiliensis Müll. Arg.) plantaitons are rapidly expanding throughout mainland Southeast Asia, potentially changing the partitioning of water, energy, and carbon at multiple scales, compared with the traditional land covers they are replacing. We have conducted eddy flux measurements in two rubber plantation sites: Som Sanuk (SS), located northern Thailand; and Cambodian Rubber Research Institute (CRRI), central Cambodia. We used combination of actual evapotranspiration (ET) flux measurements and an inversed version of a simple 2-layer ET model for estimating the mean canopy stomatal conductances (gs), which is among the most effective measures for describing the exchange characteristics. It is demonstrated how each studied rubber plantation copes with each strong seasonal drought via tree water use strategies. Potential tree water use deficit (precipitation (P) - potential evaporation (ET_POT)) for each season (i.e., December-February: DJF, March-May: MAM, June-August: JJA, and September-November: SON) revealed in which season and how the water use should be controlled. We found that in the season when actual tree water use deficit (P - ET) was negative (DJF and MAM), the deficit was compensated with soil water from the previous season at a depth of 0-2 m at the Thailand site, and from a depth of 0-3 m at CRRI. Two ecophysiological parameters, the reference value of gs (gsref) and the sensitivity of gs to atmospheric demand (m), as well as their proportionality (m/gsref), were derived from the logarithmic response curve of gs to vapor pressure deficit (D) for each season and each site. In both sites, gsref and m appeared to be less in DJF and MAM than each in the other three month periods (seasons). On average in a whole year, m/gsref was less than 0.6 at SS and almost 0.6 at the CRRI site, suggesting that there was less sufficient stomatal regulation at SS, where there might be little risk of water stress-induced hydraulic failure because of much

    Millions of people in South and Southeast Asia consume drinking water daily which contains dangerous levels of arsenic exceeding health-based recommendations [1]. A key control on arsenic mobilization in aquifers in these areas has been controversially identified as the interaction of 'labile' organic matter contained in surface waters with groundwaters and sediments at depth [2-4], which may trigger the release of arsenic from the solid- to aqueous-phase via reductive dissolution of iron-(hyr)oxide minerals [5]. In a field site in Kandal Province, Cambodia, which is an arsenic-affected area typical to others in the region, there are strong seasonal patterns in groundwater flow direction, which are closely related to monsoonal rains [6] and may contribute to arsenic release in this aquifer. The aim of this study is to explore the implications of the high susceptibility of this aquifer system to seasonal changes on potential ground-surface water interactions. The main objectives are to (i) identify key zones where there are likely ground-surface water interactions, (ii) assess the seasonal impact of such interactions and (iii) quantify the influence of interactions using geochemical parameters (such as As, Fe, NO3, NH4, 14C, 3T/3He, δ18O, δ2H). Identifying the zones, magnitude and seasonal influence of ground-surface water interactions elucidates new information regarding potential locations/pathways of arsenic mobilization and/or transport in affected aquifers and may be important for water management strategies in affected areas.

    Full Text Available In 2008, 800 adults living within rural Kampong Cham Province, Cambodia were enrolled in a prospective cohort study of zoonotic influenza transmission. After enrollment, participants were contacted weekly for 24 months to identify acute influenza-like illnesses (ILI. Follow-up sera were collected at 12 and 24 months. A transmission substudy was also conducted among the family contacts of cohort members reporting ILI who were influenza A positive. Samples were assessed using serological or molecular techniques looking for evidence of infection with human and avian influenza viruses. Over 24 months, 438 ILI investigations among 284 cohort members were conducted. One cohort member was hospitalized with a H5N1 highly pathogenic avian influenza (HPAI virus infection and withdrew from the study. Ninety-seven ILI cases (22.1% were identified as influenza A virus infections by real-time RT-PCR; none yielded evidence for AIV.

    Full Text Available INTRODUCTION: We tested two treatment strategies to determine: treatment (a prognosis (seizure frequency, mortality, suicide, and complications, (b safety and adherence of treatment, (c self-reported satisfaction with treatment and self-reported productivity, and policy aspects (a number of required tablets for universal treatment (NRT, (b cost of management, (c manpower-gap and requirements for scaling-up of epilepsy care. METHODS: We performed a random-cluster survey (N = 16510 and identified 96 cases (≥1 year of age in 24 villages. They were screened by using a validated instrument and diagnosed by the neurologists. International guidelines were used for defining and classifying epilepsy. All were given phenobarbital or valproate (cost-free in two manners patient's door-steps (March 2009-March 2010, primary-treatment-period, PTP and treatment through health-centers (March 2010-June 2011, treatment-continuation-period, TCP. The emphasis was to start on a minimum dosage and regime, without any polytherapy, according to the age of the recipients. No titration was done. Seizure-frequency was monthly and self-reported. RESULTS: The number of seizures reduced from 12.6 (pre-treatment to 1.2 (end of PTP, following which there was an increase to 3.4 (end of TCP. Between start of PTP and end of TCP, >60.0% became and remained seizure-free. During TCP, ∼26.0% went to health centers to collect their treatment. Complications reduced from 12.5% to 4.2% between start and end of PTP and increased to 17.2% between start and end of TCP. Adverse events reduced from 46.8% to 16.6% between start and end of PTP. Nearly 33 million phenobarbital 100 mg tablets are needed in Cambodia. CONCLUSIONS: Epilepsy responded sufficiently well to the conventional treatment, even when taken at a minimal dosage and a simple daily regimen, without any polytherapy. This is yet another confirmation that it is possible to substantially reduce direct burden of epilepsy

  1. Patterns of ecosystem metabolism in the Tonle Sap Lake, Cambodia with links to capture fisheries.

    Gordon W Holtgrieve

    Full Text Available The Tonle Sap Lake in Cambodia is a dynamic flood-pulsed ecosystem that annually increases its surface area from roughly 2,500 km(2 to over 12,500 km(2 driven by seasonal flooding from the Mekong River. This flooding is thought to structure many of the critical ecological processes, including aquatic primary and secondary productivity. The lake also has a large fishery that supports the livelihoods of nearly 2 million people. We used a state-space oxygen mass balance model and continuous dissolved oxygen measurements from four locations to provide the first estimates of gross primary productivity (GPP and ecosystem respiration (ER for the Tonle Sap. GPP averaged 4.1±2.3 g O2 m(-3 d(-1 with minimal differences among sites. There was a negative correlation between monthly GPP and lake level (r = 0.45 and positive correlation with turbidity (r = 0.65. ER averaged 24.9±20.0 g O2 m(-3 d(-1 but had greater than six-fold variation among sites and minimal seasonal change. Repeated hypoxia was observed at most sampling sites along with persistent net heterotrophy (GPP

  2. Factors Associated with Inconsistent Condom Use among Men Who Have Sex with Men in Cambodia.

    Full Text Available Compared to the general population, men who have sex with men (MSM are at greater risk for HIV and less understood due to their more hidden and stigmatized nature. Moreover, the discrepancy in findings in the literature merits further investigations in MSM populations from different cultures and settings. We therefore conducted this study to explore factors associated with inconsistent condom use among high-risk MSM in Cambodia.This cross-sectional study was conducted in 2014 among 367 MSM randomly selected from Battembang and Siem Reap using a two-stage cluster sampling method. A structured questionnaire was used for face-to-face interviews to collect information on characteristics of respondents, HIV testing history, self-perception of HIV risk, substance use, sexual behaviors, mental disorders, and HIV knowledge. Multivariable logistic regression analysis was performed to identify factors independently associated with inconsistent condom use.On average, 62.3% of respondents reported that they always used condoms over the past three months. The rates varied with types of sexual partners; the proportion of respondents who reported always using condoms was 55.1%, 64.2%, 75.9%, 73.0%, 78.1%, and 70.3%, for sexual partners who were girlfriends, boyfriends, female sex workers, male sex workers, female clients, or male clients, respectively. After adjustment, inconsistent condom use was significantly associated with age of ≥25 (AOR = 1.77, 95% CI = 1.09-2.86, self-rated quality of life as good or very good (AOR = 4.37, 95% CI = 1.79-5.67, self-perception of higher HIV risk compared to the general population (AOR = 2.37, 95% CI = 1.35-4.17, illicit drug use in the past three months (AOR = 5.76, 95% CI = 1.65-10.09, and reported consistent lubricant use when selling anal sex to men in the past three months (AOR = 2.85, 95% CI = 1.07-8.12.We found risky sexual behaviors to be considerably high among MSM in this study, especially among those who used

    Virak Khieu

    Full Text Available BACKGROUND: Worldwide, an estimated 30 to 100 million people are infected with Strongyloides stercoralis, a soil-transmitted helminth. Information on the parasite is scarce in most settings. In semi-rural Cambodia, we determined infection rates and risk factors; compared two diagnostic methods (Koga agar plate [KAP] culture and Baermann technique for detecting S. stercoralis infections, using a multiple stool examination approach; and assessed efficacy of ivermectin treatment. METHODS/PRINCIPAL FINDINGS: We performed a cross-sectional study in 458 children from four primary schools in semi-rural villages in Kandal province, using three diagnostic procedures (Kato-Katz, KAP culture and Baermann technique on three stool samples. Infected children were treated with ivermectin (100 µg/kg/day for two days and re-examined three weeks after treatment. Hookworm, S. stercoralis, Trichuris trichiura, and small trematode eggs were most prevalent, with 24.4% of children being infected with S. stercoralis. The sensitivity of KAP culture and Baermann technique was 88.4% and 75.0%, respectively and their negative predictive values were 96.4% and 92.5%, respectively. The cumulative prevalence of S. stercoralis increased from 18.6% to 24.4%, after analyzing three stool samples, which was close to the modeled 'true' prevalence of 24.8%. Children who reported defecating in latrines were significantly less infected with S. stercoralis than those who did not use latrines (p<0.001. Itchy skin and diarrhea were significantly associated with S. stercoralis infection. The cure rate of ivermectin was 98.3%. CONCLUSIONS/SIGNIFICANCE: S. stercoralis infection is highly prevalent among semi-rural Cambodian schoolchildren. The sensitivity of KAP culture is higher than that of the Baermann technique. In the absence of a "gold standard", analysis of multiple stool samples by different diagnostic methods is required to achieve a satisfactory level of sensitivity. Almost three

    In Cambodia, despite great achievements in reducing the prevalence of HIV in the general population, reducing new HIV infections among young at-risk women remains a challenge. This study was designed to examine the prevalence of risky behaviors of sexually active female youth in Cambodia and to explore risk factors associated with engagement in transactional sex. We surveyed sexually active female youth aged 10-24 enrolled at risk "hotspots" in eight provinces in Cambodia. We collected data on demographic factors, sexual behavior, and factors hypothesized to be associated with transactional sex. Multivariable logistic regression was used to identify associations between demographic and sexual behavior and transactional sex. Of the 280 respondents, the mean age was 21.2, and 48.1% had been paid for sex in the past year. After adjustment, at-risk females who were never have been married (adjusted odds ratio (AOR) 3.40, 95% confidence interval (CI) = 1.65-6.97), have completed less than 6 years of school (AOR 3.26, 95% CI = 1.60-6.66), have 1 or more parents who had died (AOR 4.34, 95% CI = 2.00-9.38), be a heavy alcohol drinker (AOR 3.58, 95% CI = 1.78-7.18), have used a condom with their boyfriend during last sexual encounter (AOR 3.50, 95% CI = 1.68-7.32), and have ever had an HIV test (AOR 3.51, 95% CI = 1.68-7.32) were more likely to engage in sex work. Our findings suggest that prevention strategies for female youth at risk of engagement in sex work should include upstream structural interventions that aim to encourage girls' education and empowerment. In addition, tailored sex education and behavior change messaging about the risks of heavy drinking, condom use with romantic partners, and the importance of frequent HIV testing for at-risk youth and sex workers should be designed and delivered to youth currently engaging in sex work.

    Full Text Available Abstract Background Suicide among young people is a global public health problem, but adequate information on determinants of suicidal expression is lacking in middle and low income countries. Young people in transitional economies are vulnerable to psychosocial stressors and suicidal expressions. This study explores the suicidal expressions and their determinants among high school students in Cambodia, with specific focus on gender differences. Methods A sample of 320 young people, consisting of 153 boys and 167 girls between 15-18 years of age, was randomly selected from two high schools in Cambodia. Their self-reported suicidal expressions, mental health problems, life-skills dimensions, and exposure to suicidal behavior in others were measured using the Youth Self-Report (YSR, Life-Skills Development Scale (LSDS-Adolescent Form, and Attitude Towards Suicide (ATTS questionnaires. Results Suicidal plans were reported more often by teenage boys than teenage girls (M = 17.3%, F = 5.6%, p = 0.001, whereas girls reported more attempts (M = 0.6%, F = 7.8%, p = 0.012. Young men scored significantly higher on rule-breaking behavior than young women (p = 0.001, whereas young women scored higher on anxious/depression (p = 0.000, withdrawn/depression (p = 0.002, somatic complaints (p = 0.034, social problems (p = 0.006, and internalizing syndrome (p = 0.000. Young men exposed to suicide had significantly higher scores for internalizing syndrome compared to those unexposed (p = 0.001, while young women exposed to suicide scored significantly higher on both internalizing (p = 0.001 and externalizing syndromes (p = 0.012. Any type of exposure to suicidal expressions increased the risk for own suicidal expressions in both genders (OR = 2.04, 95% CI = 1.06-3.91; among young women, however, those exposed to suicide among friends and partners were at greater risk for the serious suicidal expressions (OR = 2.79, 95% CI = 1.00-7.74.

    Full Text Available Abstract Background In Cambodia, malaria transmission is low and most cases occur in forested areas. Sero-epidemiological techniques can be used to identify both areas of ongoing transmission and high-risk groups to be targeted by control interventions. This study utilizes repeated cross-sectional data to assess the risk of being malaria sero-positive at two consecutive time points during the rainy season and investigates who is most likely to sero-convert over the transmission season. Methods In 2005, two cross-sectional surveys, one in the middle and the other at the end of the malaria transmission season, were carried out in two ecologically distinct regions in Cambodia. Parasitological and serological data were collected in four districts. Antibodies to Plasmodium falciparum Glutamate Rich Protein (GLURP and Plasmodium vivax Merozoite Surface Protein-119 (MSP-119 were detected using Enzyme Linked Immunosorbent Assay (ELISA. The force of infection was estimated using a simple catalytic model fitted using maximum likelihood methods. Risks for sero-converting during the rainy season were analysed using the Classification and Regression Tree (CART method. Results A total of 804 individuals participating in both surveys were analysed. The overall parasite prevalence was low (4.6% and 2.0% for P. falciparum and 7.9% and 6.0% for P. vivax in August and November respectively. P. falciparum force of infection was higher in the eastern region and increased between August and November, whilst P. vivax force of infection was higher in the western region and remained similar in both surveys. In the western region, malaria transmission changed very little across the season (for both species. CART analysis for P. falciparum in the east highlighted age, ethnicity, village of residence and forest work as important predictors for malaria exposure during the rainy season. Adults were more likely to increase their antibody responses to P. falciparum during the

    Full Text Available Abstract Background Continued progress towards global reduction in morbidity and mortality due to malaria requires scale-up of effective case management with artemisinin-combination therapy (ACT. The first case of artemisinin resistance in Plasmodium falciparum was documented in western Cambodia. Spread of artemisinin resistance would threaten recent gains in global malaria control. As such, the anti-malarial market and malaria case management practices in Cambodia have global significance. Methods Nationally-representative household and outlet surveys were conducted in 2009 among areas in Cambodia with malaria risk. An anti-malarial audit was conducted among all public and private outlets with the potential to sell anti-malarials. Indicators on availability, price and relative volumes sold/distributed were calculated across types of anti-malarials and outlets. The household survey collected information about management of recent "malaria fevers." Case management in the public versus private sector, and anti-malarial treatment based on malaria diagnostic testing were examined. Results Most public outlets (85% and nearly half of private pharmacies, clinics and drug stores stock ACT. Oral artemisinin monotherapy was found in pharmacies/clinics (9%, drug stores (14%, mobile providers (4% and grocery stores (2%. Among total anti-malarial volumes sold/distributed nationally, 6% are artemisinin monotherapies and 72% are ACT. Only 45% of people with recent "malaria fever" reportedly receive a diagnostic test, and the most common treatment acquired is a drug cocktail containing no identifiable anti-malarial. A self-reported positive diagnostic test, particularly when received in the public sector, improves likelihood of receiving anti-malarial treatment. Nonetheless, anti-malarial treatment of reportedly positive cases is low among people who seek treatment exclusively in the public (61% and private (42% sectors. Conclusions While data on the anti

    Full Text Available Abstract Background Malaria transmission is highly heterogeneous, especially in low endemic countries, such as Cambodia. This results in geographical clusters of residual transmission in the dry, low transmission season, which can fuel the transmission to wider areas or populations during the wet season. A better understanding of spatial clustering of malaria can lead to a more efficient, targeted strategy to reduce malaria transmission. This study aims to evaluate the potential of the use of serological markers to define spatial patterns in malaria exposure. Methods Blood samples collected in a community-based randomized trial performed in 98 high endemic communities in Ratanakiri province, north-eastern Cambodia, were screened with a multiplex serological assay for five serological markers (three Plasmodium falciparum and two Plasmodium vivax. The antibody half-lives range from approximately six months until more than two years. Geographical heterogeneity in malaria transmission was examined using a spatial scan statistic on serology, PCR prevalence and malaria incidence rate data. Furthermore, to identify behavioural patterns or intrinsic factors associated with malaria exposure (antibody levels, risk factor analyses were performed by using multivariable random effect logistic regression models. The serological outcomes were then compared to PCR prevalence and malaria incidence data. Results A total of 6502 samples from two surveys were screened in an area where the average parasite prevalence estimated by PCR among the selected villages is 3.4 %. High-risk malaria pockets were observed adjacent to the ‘Tonle San River’ and neighbouring Vietnam for all three sets of data (serology, PCR prevalence and malaria incidence rates. The main risk factors for all P. falciparum antigens and P. vivax MSP1.19 are age, ethnicity and staying overnight at the plot hut. Conclusion It is possible to identify similar malaria pockets of higher malaria

    Full Text Available BACKGROUND: Dengue vaccines are now in late-stage development, and evaluation and robust estimates of dengue disease burden are needed to facilitate further development and introduction. In Cambodia, the national dengue case-definition only allows reporting of children less than 16 years of age, and little is known about dengue burden in rural areas and among older persons. To estimate the true burden of dengue in the largest province of Cambodia, Kampong Cham, we conducted community-based active dengue fever surveillance among the 0-to-19-year age group in rural villages and urban areas during 2006-2008. METHODS AND FINDINGS: Active surveillance for febrile illness was conducted in 32 villages and 10 urban areas by mothers trained to use digital thermometers combined with weekly home visits to identify persons with fever. An investigation team visited families with febrile persons to obtain informed consent for participation in the follow-up study, which included collection of personal data and blood specimens. Dengue-related febrile illness was defined using molecular and serological testing of paired acute and convalescent blood samples. Over the three years of surveillance, 6,121 fever episodes were identified with 736 laboratory-confirmed dengue virus (DENV infections for incidences of 13.4-57.8/1,000 person-seasons. Average incidence was highest among children less than 7 years of age (41.1/1,000 person-seasons and lowest among the 16-to-19-year age group (11.3/1,000 person-seasons. The distribution of dengue was highly focal, with incidence rates in villages and urban areas ranging from 1.5-211.5/1,000 person-seasons (median 36.5. During a DENV-3 outbreak in 2007, rural areas were affected more than urban areas (incidence 71 vs. 17/1,000 person-seasons, p<0.001. CONCLUSION: The large-scale active surveillance study for dengue fever in Cambodia found a higher disease incidence than reported to the national surveillance system, particularly

    This study tested a low-cost method for estimating suicide rates in developing nations that lack adequate statistics. Data comprised reported suicides from Cambodia's 2 largest newspapers. Capture-recapture modeling estimated a suicide rate of 3.8/100 000 (95% CI = 2.5-6.7) for 2012. That compares to World Health Organization estimates of 1.3 to 9.4/100 000 and a Cambodian government estimate of 3.5/100 000. Suicide rates of males were twice that of females, and rates of those cost and can be applied to regions with at least 2 newspapers with overlapping reports. Means to further improve this approach are discussed. These methods are applicable to both recent and historical data, which can benefit epidemiological work, and may also be applicable to homicides and other statistics.

    Migrant beer promoters in Cambodia, Laos, Thailand, and Vietnam were surveyed to determine their experiences in accessing reproductive health care services in the cities of Phnom Penh, Vientiane, Bangkok, and Hanoi. A total of 7 health care institutions were chosen as popular with migrant beer promoters. Staff at these institutions provided information on the institution, and 390 beer promoters were surveyed about their experiences while accessing services. There were discrepancies between findings from the staff interviews and the experiences of the beer promoters. In general, the migrant women were satisfied with the cost, location, friendliness of the health care providers, and knowledge and skills of the providers. They were less positive about confidentiality and waiting times, though many still agreed that these were not an issue. Health care planners and providers should take note of the issues affecting access to reproductive health care services for migrant women when they design and implement services.

    Women with disabilities (WWDs) are at triple jeopardy due to the combined risks associated with gender, disability, and violence. Not only are WWDs marginalized socially but the violence against them in their own homes is largely neglected in domestic violence research. Evidence from developing countries is particularly sparse. A cross-sectional survey conducted in Cambodia found rates of violence by household members besides intimate partners were significantly higher among WWDs than non-disabled women. This violence engendered increased levels of psychological distress and higher rates of physical injury but low rates of disclosure to health workers and other formal sources of potential support. Community-based strategies are recommended to radically change social and cultural attitudes, beliefs, and responses to WWDs who are victims of household violence to reduce negative social reactions toward them and to make it safer for them to disclose and receive psychosocial, legal, and other necessary support for this underreported type of violence.

    Organophosphates and carbamates (OPs/CMs) are known for their acetylcholinesterase inhibiting character. A cross-sectional study of pesticide handling practices and self-perceived symptoms of acute pesticide poisoning was conducted using questionnaire-based interviews with 89 pesticide sprayers...... in Boeung Cheung Ek (BCE) Lake, Phnom Penh, Cambodia. The study showed that 50% of the pesticides used belonged to WHO class I + II and personal protection among the farmers were inadequate. A majority of the farmers (88%) had experienced symptoms of acute pesticide poisoning, and this was significantly...... associated with the number of hours spent spraying with OPs/CMs (OR = 1.14, CI 95%: 1.02-1.28). The higher educated farmers reduced their risk of poisoning by 55% for each extra personal protective measure they adapted (OR = 0.45, CI 95%: 0.22-0.91). These findings suggest that improving safe pesticide...

  15. From subjects to relations: Bioethics and the articulation of postcolonial politics in the Cambodia Pre-Exposure Prophylaxis trial.

    Controversies about global clinical trials, particularly HIV trials, tend to be framed in terms of ethics. In this article, I explore debates about ethics in the Cambodia Pre-Exposure Prophylaxis trial, which was designed to test the safety and efficacy of tenofovir as a prevention for HIV infection. Bringing together studies of public participation in science with studies of bioethics, I show how activists around the Cambodian Pre-Exposure Prophylaxis trial circulated and provoked debates about standards of research ethics, as opposed to research methodology. This postcolonial bioethics was configured through the circulation of and debate about ethics guidelines, and historically and culturally specific relations of vulnerability and responsibility between foreigners and Cambodians and between Cambodian leaders and Cambodian subjects. I argue that this shift in the object of ethical concern, from the experimental human subject to the relation between subjects and researchers, illustrates how a postcolonial field of articulation reformulates classical bioethics.

    Full Text Available This systematic review elaborates the concepts and impacts of border malaria, particularly on the emergence and spread of Plasmodium falciparum and Plasmodium vivax multidrug resistance (MDR malaria on Thailand-Myanmar and Thailand-Cambodia borders. Border malaria encompasses any complex epidemiological settings of forest-related and forest fringe-related malaria, both regularly occurring in certain transmission areas and manifesting a trend of increased incidence in transmission prone areas along these borders, as the result of interconnections of human settlements and movement activities, cross-border population migrations, ecological changes, vector population dynamics, and multidrug resistance. For regional and global perspectives, this review analyzes and synthesizes the rationales pertaining to transmission dynamics and the vulnerabilities of border malaria that constrain surveillance and control of the world’s most MDR falciparum and vivax malaria on these chaotic borders.

    Abstract In 2005, Cambodia passed the Sub‐Decree on Marketing of Products for Infant and Young Child Feeding (no. 133) to regulate promotion of commercial infant and young child food products, including breastmilk substitutes. Helen Keller International assessed mothers' exposure to commercial promotions for breastmilk substitutes and use of these products through a cross‐sectional survey among 294 mothers of children less than 24 months of age. Eighty‐six per cent of mothers reported observing commercial promotions for breastmilk substitutes, 19.0% reported observing infant and young child food product brands/logos on health facility equipment and 18.4% reported receiving a recommendation from a health professional to use a breastmilk substitute. Consumption of breastmilk substitutes was high, occurring among 43.1% of children 0–5 months and 29.3% of children 6–23 months of age. Findings also indicated a need to improve breastfeeding practices among Phnom Penh mothers. Only 36.1% of infants 0–5 months of age were exclusively breastfed, and 12.5% of children 20–23 months of age were still breastfed. Children that received a breastmilk substitute as a prelacteal feed were 3.9 times more likely to be currently consuming a breastmilk substitute than those who did not. Despite restriction of commercial promotions for breastmilk substitutes without government approval, occurrence of promotions is high and use is common among Phnom Penh mothers. In a country with high rates of child malnutrition and pervasive promotions in spite of restrictive national law, full implementation of Cambodia's Sub‐Decree 133 is necessary, as are policies and interventions to support exclusive and continued breastfeeding. Key messages Despite prohibition without specific approval by the national government, companies are pervasively promoting breast‐milk substitutes in Phnom Penh, particularly on television and at points of sale.Strengthened implementation and enforcement

    ABSTRACT The purpose of the study was to investigate perceived teeth health status and oral health behavior, as well as their correlates, among adolescents in Cambodia. The analysis included 3806 Cambodian school children (mean age 15.7 years, SD=1.8 years) who took part in the “Global School-based Student Health Survey” (GSHS) in 2013. Overall, 7.8% of the students reported poor perceived teeth status, 18.0% had missed school in the past year because of a toothache, 26.7% engaged in combined oral health behavior (brushing teeth twice daily or more often = 79.8%, using fluoride toothpaste = 59.9%, and drinking soft drinks less than once a day = 53.6%), and 59.9% had never visited a dentist for a routine examination or other dental work. In the multivariate logistic regression analysis, older age, being female, missing school because of a toothache, having a toothache in the past 12 months, poor oral health behavior and sedentary leisure time were associated with poor perceived teeth status. Older age, good perceived teeth status, having had a dental check-up, washing hands before eating and after toilet use, and not eating fast food were associated with a positive oral health behavior (brushing teeth twice daily or more often, using fluoride toothpaste, and drinking soft drinks less than once a day). Significant proportions of poor perceived teeth status and poor oral health behavior were found among school children in Cambodia. Various risk factors (sociodemographic, dental variables, general health risk behaviors) for perceived poor teeth status, oral health behavior and never having had a dental check-up were identified, which can be utilized for intervention programs.

    Full Text Available Natural seasonal waterholes (trapeang in Khmer are an important feature of the deciduous dipterocarp forests of eastern Cambodia and are utilised by a number of globally threatened species of large ungulates and waterbirds. However at the end of the dry-season (April only a small proportion of waterholes retain water. In 2011, we artificially deepened six waterholes in the core area of Mondulkiri Protected Forest, eastern Cambodia, removing 3m3 to 24m3 of earth (mean 16.5m3 from each.  Surveys prior to deepening demonstrated that only one of these waterholes, and 10% of all waterholes surveyed in the study area (n=50, held water at the end of the dry-season.  Following modification five of the six deepened waterholes (83% held water at the end of the subsequent dry-season. From four camera traps over 448 trap-nights, 23 species including two globally threatened large ungulates, Banteng Bos javanicus and Eld’s Deer Rucervus eldii, and two Critically Endangered Ibises (Giant Thaumatibis gigantea and White-shouldered Ibis Pseudibis davisoni, were photographed foraging and drinking at the deepened waterholes between March and June 2012.  Our results suggest that artificial deepening of natural waterholes does not cause damage, and makes these waterholes suitable for use throughout the dry-season.  In the face of changing climate it is suggested that management plans should have a programme for the survey and determination of the status of waterholes every year and improve the use of water resources by artificial deepening.

    At present, there is very limited information on the ecology, distribution, and structure of Cambodia's tree species to warrant suitable conservation measures. The aim of this study was to assess various methods of analysis of aerial imagery for characterization of the forest mensuration variables (i.e., tree height and crown width) of selected tree species found in the forested region around the temples of Angkor Thom, Cambodia. Object-based image analysis (OBIA) was used (using multiresolution segmentation) to delineate individual tree crowns from very-high-resolution (VHR) aerial imagery and light detection and ranging (LiDAR) data. Crown width and tree height values that were extracted using multiresolution segmentation showed a high level of congruence with field-measured values of the trees (Spearman's rho 0.782 and 0.589, respectively). Individual tree crowns that were delineated from aerial imagery using multiresolution segmentation had a high level of segmentation accuracy (69.22%), whereas tree crowns delineated using watershed segmentation underestimated the field-measured tree crown widths. Both spectral angle mapper (SAM) and maximum likelihood (ML) classifications were applied to the aerial imagery for mapping of selected tree species. The latter was found to be more suitable for tree species classification. Individual tree species were identified with high accuracy. Inclusion of textural information further improved species identification, albeit marginally. Our findings suggest that VHR aerial imagery, in conjunction with OBIA-based segmentation methods (such as multiresolution segmentation) and supervised classification techniques are useful for tree species mapping and for studies of the forest mensuration variables.

    Full Text Available Abstract Background Drug susceptibility testing (DST remains an important concern for implementing treatment of MDR tuberculosis patients. Implementation of molecular tests for drug resistance identification would facilitate DST particularly in developing countries where culturing is difficult to perform. We have characterized multidrug resistant strains in Cambodia using MDTDRsl tests, drug target sequencing and phenotypic tests. Methods A total of 65 non-MDR and 101 MDR TB isolates collected between May 2007 and June 2009 were tested for resistance to fluoroquinolones and aminoglycosides/cyclic peptides using the GenoType® MTBDRsl assay and gene sequencing. Rifampicin resistance (RMP-R was tested using gene sequencing and genotyping was assessed by spoligotyping. Results A total of 95 of the 101 MDR strains were confirmed to be RMP-R by rpoB gene sequencing. Fourteen of the 101 MDR isolates (14% carried a gyrA mutation associated with fluoroquinolone-resistance (FQ-R (detected by the MTBDRsl assay and sequencing compared with only 1 (1.5% of the 65 non-MDR strains. Only 1 (1% of the MDR isolates was found to be XDR TB. The MDR group contained a higher proportion of Beijing or Beijing like strains (58% than the non MDR group (28%. This percentage is higher in MDR FQ-R strains (71%. Conclusions The new GenoType® MTBDRsl assay combined with molecular tests to detect RMP-R and isoniazid resistance (INH-R represents a valuable tool for the detection of XDR TB. In Cambodia there is a low rate of XDR amongst MDR TB including MDR FQ-R TB. This suggests a low association between FQ-R and XDR TB. Strain spoligotyping confirms Beijing strains to be more prone to accumulate antibiotic resistance.

    In this study, we investigated the molecular evidence of Trypanosoma evansi in wild rodents from Cambodia, Lao PDR and Thailand. Between November 2007 and June 2009, 1664 rodents were trapped at eight sites representative of various ecological habitats. Of those animals, 94 were tested by direct microscopic blood examination, 633 using the Card Agglutination Test for Trypanosomes (CATT/T. evansi) and 145 by Polymerase Chain Reaction (PCR) with two sets of primers: TRYP1 (amplifying ITS1 of ribosomal DNA of all trypanosomes) and TBR (amplifying satellite genomic DNA of Trypanozoon parasites). Using TRYP1, based on the size of the PCR products, 15 samples from the three countries were positive for Trypanosoma lewisi (two were confirmed by sequencing), and three were positive for Trypanozoon (one was confirmed by sequencing and three by TBR primers); the specificity of the primers failed as rodent DNA was amplified in some cases. Using TBR, six samples were positive for Trypanozoon (one was confirmed by sequencing); as T. evansi is the only species of the Trypanozoon sub-genus possibly present in Asian rodents, these results confirmed its presence in rodents from Thailand (Rattus tanezumi) and Cambodia (R. tanezumi, Niviventer fulvescens & Maxomys surifer). Further investigations are necessary to establish the situation in Lao PDR. None of the 16 samples most strongly positive to the CATT proved to be positive for Trypanozoon by PCR. The merits of the CATT for such studies were not confirmed. Studying the urban and rural circulation of these parasites in rodents will enable an evaluation of human exposure and infection risk, as human infections by T. evansi were recently described in India and by T. lewisi in India and Thailand. As sequencing PCR products is expensive, the development of new molecular and serological tools for rodents would be very useful.

    Angiostrongylus cantonensis is a zoonotic nematode parasite causing human eosinophilic meningitis (or meningoencephalitis) worldwide. A closely related species, Angiostrongylus malaysiensis, might also be a human pathogen. Larvae were obtained from land snails in Lao PDR, Cambodia, Myanmar and Thailand. We sequenced two nuclear gene regions (nuclear ribosomal ITS2 and SSU rRNA) and a portion of one mitochondrial gene (COI) from these larvae. Angiostrongylus cantonensis and A. malaysiensis were identified. This is the first report of the molecular identification of the two Angiostrongylus species in Lao PDR, Cambodia and Myanmar. The regional distributions of the two species broadly overlap. Phylogenetic relationships were inferred including data from Angiostrongylus species deposited in public databases. All the gene regions we sequenced have potential value in distinguishing between species of Angiostrongylus. The COI gene exhibited the greatest intraspecific variation in the study region (five haplotypes in A. cantonensis and four in A. malaysiensis) and might be suitable for more detailed phylogeographic studies.

    Hegde, Shalika; Hoban, Elizabeth; Nevill, Annemarie

    2012-11-01

    Reproductive health research and policies in Cambodia focus on safe motherhood programs particularly for married women, ignoring comprehensive fertility regulation programs for unmarried migrant women of reproductive age. Maternal mortality risks arising due to unsafe abortion methods practiced by unmarried Cambodian women, across the Thai-Cambodia border, can be considered as a public health emergency. Since Thailand has restrictive abortion laws, Cambodian migrant women who have irregular migration status in Thailand experimented with unsafe abortion methods that allowed them to terminate their pregnancies surreptitiously. Unmarried migrant women choose abortion as a preferred birth control method seeking repeat "unsafe" abortions instead of preventing conception. Drawing on the data collected through surveys, in-depth interviews, and document analysis in Chup Commune (pseudonym), Phnom Penh, and Bangkok, the authors describe the public health dimensions of maternal mortality risks faced by unmarried Cambodian migrant women due to various unsafe abortion methods employed as birth control methods.

    In recent years, Cambodia has seen a significant economic growth. However, this development has not reached the poorest dwellers, resulting in escalating inequality. The Tonle Sap Region is one of the poorest regions in the country. The livelihoods of the region's poor are greatly dependent on water resources. The livelihoods are thus vulnerable to possible changes in water resources associated with the current development plans. By contrast, Phnom Penh, which is the main destination for the ...

    2015-01-01

    This paper focuses on the procedural challenges of using the Victim Information Forms (VIFs) to analyze survivors' experiences with the Extraordinary Chambers in the Courts of Cambodia (ECCC), commonly known as the Khmer Rouge Tribunal. The paper takes a systematic public/medical sociology approach to examining the VIF as a participatory rights mechanism for victims wishing to pursue justice for themselves and their loved ones who experienced the Khmer Rouge atrocities, torture, forced relocation, starvation, forced labor, rape, robbery, and other physical and psychological torment, firsthand. It provides the first comparative, critical analysis of both the original VIF and the revised form issued midway through the submission period; both forms appear as appendices to the paper. Conclusions are drawn and suggestions made by the researcher based on the firsthand collection and submission of the largest group of VIFs from any single source around the world (outside of Cambodia itself), as well as on support work with victims/survivors during the ECCC proceedings in Phnom Penh, Cambodia in 2013.

    Vitamin B12 plays an essential role in fetal and infant development. In regions where animal source food consumption is low and perinatal supplementation is uncommon, infants are at risk of vitamin B12 deficiency. In this secondary analysis, we measured total vitamin B12 concentrations in maternal and infant serum/plasma and breast milk among two samples of mother-infant dyads in Canada (assessed at 8 weeks post-partum) and in Cambodia (assessed between 3-27 weeks post-partum). Canadian mothers (n = 124) consumed a daily vitamin B12-containing multiple micronutrient supplement throughout pregnancy and lactation; Cambodian mothers (n = 69) were unsupplemented. The maternal, milk, and infant total vitamin B12 concentrations (as geometric means (95% CI) in pmol/L) were as follows: in Canada, 698 (648,747), 452 (400, 504), and 506 (459, 552); in Cambodia, 620 (552, 687), 317 (256, 378), and 357 (312, 402). The majority of participants were vitamin B12 sufficient (serum/plasma total B12 > 221 pmol/L): 99% and 97% of mothers and 94% and 84% of infants in Canada and Cambodia, respectively. Among the Canadians, maternal, milk, and infant vitamin B12 were all correlated (p B12 were correlated among the Cambodians (p < 0.001).

With funding from the Australian Department of Foreign Affairs and Trade, FHI 360 supported the Ministry of Interior to implement the Police Community Partnership Initiative (PCPI in Cambodia's capital Phnom Penh. To guide this, FHI 360 conducted a baseline study examining police and key populations’ attitudes and practices towards one another, including fear and occurrence of arrest. Methods: Between December 2012 and January 2013, a cross-sectional survey of 199 police post officers, 199 people who use drugs (PWUD including people who inject drugs (PWID, 199 men who have sex with men (MSM, 200 transgender women (TGW and 200 female entertainment workers (FEW was conducted in five Phnom Penh districts. Eligible participants were ≥18 years, members of a key population from selected hotspots or police officers, deputy chiefs or chiefs. Results: Key populations’ median age was 25 years (IQR: 22–30; 40% had completed only primary school. Police were male (99.5%, with median age 43 years (IQR: 30 to 47, and 45 and 25% high school and university completion rates, respectively. Key populations feared arrest for carrying needles and syringes (67%, condoms (23% and 19% felt afraid to access health services. Close to 75% of police reported body searching and 58% arresting key populations in the past six months for using drugs (64%, selling or distributing drugs (36% or being violent (13%.

    ABSTRACT The aim of this study was to examine the associations of alcohol use with sociodemographic factors, mental health and alcohol exposure among school-going adolescents in Cambodia. The analysis included 3,806 school children, mean age 15.7 years (SD=1.8), from Cambodia who participated in the “Global School-based Student Health Survey” (GSHS) in 2013. The results indicate that overall, 10.0% of the students reported current alcohol use, 10.8% lifetime drunkenness, and 2.8% problem drinking. In multivariate logistic regression analysis, sociodemographic factors (older age and being male), mental health and other variables (bullying victimization, OR (odds ratio) = 1.99; 95% Confidence Interval (CI) [1.50, 2.65] and OR = 2.15; 95% CI [1.58, 3.21], respectively; having attempted suicide, OR = 2.04; 95% CI [1.35, 3.08] and OR = 2.06; 95% CI [1.29, 3.28], respectively and illicit drug use, OR = 4.97; 95% CI [2.41, 10.24] OR = 5.05; 95% CI [2.14, 11.98], respectively) and alcohol exposure variables (peer influence on drinking alcohol, OR = 6.68; 95% CI [4.75, 9.39] and OR = 7.83; 95% CI [5.73, 10.66], respectively and daily or almost daily to alcohol advertising in the past 30 days OR = 1.61; 95% CI [1.03, 2.51] and OR = 2.30; 95% CI [1.40, 3.77], respectively) were significantly positively associated with current alcohol use and drunkenness. Moreover, older age, being male, bullying victimization, having close friends, suicide attempt, drug use, father or male guardian drinks alcohol and peer influence were associated with problem drinking. There is a need to implement public health interventions with a special focus on the determinants of alcohol consumption, including exposure to alcohol advertising, in this age group. PMID:28008197

    Pyronaridine-artesunate efficacy for the treatment of uncomplicated Plasmodium falciparum malaria was assessed in an area of artemisinin resistance in western Cambodia. This nonrandomized, single-arm, observational study was conducted between 2014 and 2015. Eligible patients were adults or children with microscopically confirmed P. falciparum infection and fever. Patients received pyronaridine-artesunate once daily for 3 days, dosed according to body weight. The primary outcome was an adequate clinical and parasitological response (ACPR) on day 42, estimated by using Kaplan-Meier analysis, PCR adjusted to exclude reinfection. One hundred twenty-three patients were enrolled. Day 42 PCR-crude ACPRs were 87.2% (95% confidence interval [CI], 79.7 to 92.6%) for the overall study, 89.8% (95% CI, 78.8 to 95.3%) for Pursat, and 82.1% (95% CI, 68.4 to 90.2%) for Pailin. Day 42 PCR-adjusted ACPRs were 87.9% (95% CI, 80.6 to 93.2%) for the overall study, 89.8% (95% CI, 78.8 to 95.3%) for Pursat, and 84.0% (95% CI, 70.6 to 91.7%) for Pailin (P = 0.353 by a log rank test). Day 28 PCR-crude and -adjusted ACPRs were 93.2% (95% CI, 82.9 to 97.4%) and 88.1% (95% CI, 75.3 to 94.5%) for Pursat and Pailin, respectively. A significantly lower proportion of patients achieved day 3 parasite clearance in Pailin (56.4% [95% CI, 43.9 to 69.6%]) than in Pursat (86.7% [95% CI, 76.8 to 93.8%]; P = 0.0019). Fever clearance was also extended at Pailin versus Pursat (P < 0.0001). Most patients (95.9% [116/121]) harbored P. falciparum kelch13 C580Y mutant parasites. Pyronaridine-artesunate was well tolerated; mild increases in hepatic transaminase levels were consistent with data from previous reports. Pyronaridine-artesunate efficacy was below the World Health Organization-recommended threshold at day 42 for medicines with a long half-life (90%) for first-line treatment of P. falciparum malaria in western Cambodia despite high efficacy elsewhere in Asia and Africa.

    Full Text Available Abstract Whilst some populations have recently experienced dramatic declines in malaria, the majority of those most at risk of Plasmodium falciparum malaria still lack access to effective treatment with artemisinin combination therapy (ACT and others are already facing parasites resistant to artemisinins. In this context, there is a crucial need to improve both access to and targeting of ACT through greater availability of good quality ACT and parasitological diagnosis. This is an issue of increasing urgency notably in the private commercial sector, which, in many countries, plays an important role in the provision of malaria treatment. The Affordable Medicines Facility for malaria (AMFm is a recent initiative that aims to increase the provision of affordable ACT in public, private and NGO sectors through a manufacturer-level subsidy. However, to date, there is little documented experience in the programmatic implementation of subsidized ACT in the private sector. Cambodia is in the unique position of having more than 10 years of experience not only in implementing subsidized ACT, but also rapid diagnostic tests (RDT as part of a nationwide social marketing programme. The programme includes behaviour change communication and the training of private providers as well as the sale and distribution of Malarine, the recommended ACT, and Malacheck, the RDT. This paper describes and evaluates this experience by drawing on the results of household and provider surveys conducted since the start of the programme. The available evidence suggests that providers' and consumers' awareness of Malarine increased rapidly, but that of Malacheck much less so. In addition, improvements in ACT and RDT availability and uptake were relatively slow, particularly in more remote areas. The lack of standardization in the survey methods and the gaps in the data highlight the importance of establishing a clear system for monitoring and evaluation for similar initiatives

    Despite national improvements in child survival, 40% of Cambodian children less than 5 years of age are stunted. Commercially produced complementary foods could be nutritionally beneficial for young children in Cambodia if fortified and of optimal nutrient composition. However, other nutrient-poor commercially produced snack foods may be detrimental to young child feeding by displacing consumption of other nutritious foods. This study assessed consumption of commercial food products among infants and young children and their mothers' exposure to promotions for these products. A cross-sectional survey was conducted among 294 mothers of children less than 24 months of age living in Phnom Penh. Of children 6-23 months of age, 55.0% consumed a commercially produced snack food product on the prior day, and 80.6% had consumed one in the prior week. Only 12 (5.4%) children 6-23 months of age had consumed a commercially produced complementary food. Almost all mothers (96.9%) had observed a promotion for a commercially produced snack food product, and 29.3% reported observation of a promotion for a commercial complementary food. Only one-third (32.9%) of children 6-23 months of age achieved a minimum acceptable diet. Findings indicate that there is a need to improve infant and young child feeding practices among children less than 24 months of age living in Phnom Penh. Nutritious options should be promoted, and consumption of unhealthy commercially produced snack food products should be discouraged.

  15. Can economic incentives enhance adoption and use of a household energy technology? Evidence from a pilot study in Cambodia

    While much work has examined approaches to increase uptake of a variety of household environmental, health and energy technologies, researchers and policymakers alike have struggled to ensure long-term use. Drawing on a pilot-scale experiment conducted in rural Cambodia, this study evaluates whether economic incentives enhance continued use of—and fuel savings from—improved cookstoves (ICS). Capital-cost subsidies that have been traditionally employed to enhance ICS adoption were augmented with rebates linked to stated and objectively measured use in order to investigate impacts on both initial and sustained adoption in the treatment group. Results show that households do respond to these rebates by adopting the intervention ICS at significantly higher rates, and by using it more frequently and for longer periods. Consistent with these stove-use patterns, solid-fuel use and time spent collecting or preparing fuels also decline. However, this effect appears to diminish over time. Thus, while economic inducements may significantly increase adoption and use of new environmental health technologies, corresponding reductions in environmental or livelihood burdens are not guaranteed. Additional research on the design and implementation of incentive-based interventions targeting households directly—such as carbon financing or other forms of results-based financing (RBF) for improved cookstoves—therefore seems warranted prior to wider implementation of such solutions.

    Full Text Available This article aims to analyze three significant examples of defensive walls from South-East Asia made of solid stone blocks (both rock as well as stone-like laterite and provided with different but equivalent functions –a fortified imperial capital-city (Angkor Thom, in Cambodia, a fortified royal citadel (Ho Citadel, in the North of Vietnam and a royal palace with a partly fortified appearance (Ratu Boko, in Java Island, Indonesia–, focusing on their constructive and technical characteristics and establishing parallels between them and their closest counterparts, from China and India. We will see how their design and structure can be closely related to the fortifications of neighbouring empires, as places of origin of their strong cultural influences and, at the same time, we will try to identify the local particularities. We will pay special attention to the form of the fortified enceintes, considering the long tradition of the quadrangular plan in the walls of royal capitals, inspired in the ideal model of Chinese and Indian cities. Our research also make us think that the walls of Ratu Boko, despite their functions as symbolic limits or for retaining the soil, could also have had a defensive purpose, no matter if secondary, or at least they could be used to provide protection to the complex in case of external menace.

    Maps showing gradations of risk of fasciolosis due to Fasciola gigantica in Cambodia were produced using geographic information systems (GIS) technology in conjunction with determinants of fasciolosis. A comparison between levels of risk predicted by the maps and field measurements of prevalence in 11 provinces (n=1406) showed general agreement, which suggested the epidemiological determinants and weightings used to produce the maps were appropriate. However, due to logistical constraints, prevalence was measured at the provincial level and animals were not randomly sampled (and thus were unlikely to be representative of variability within provinces). To address this, additional field work was carried out to measure prevalence in more detail--faecal samples were collected from a randomly selected set of animals in four districts across a representative province for areas predicted to be at high risk (n=311), moderate risk (n=268) and no risk (n=262). As with the original field survey, the results show general agreement between prevalence and risk predicted by the maps, with the best fit found for areas predicted to be at high risk.

    Cynomolgus macaques, frequently used in drug metabolism studies, are bred mainly in the countries of Asia; however, comparative studies of drug metabolism between cynomolgus macaques bred in these countries have not been conducted. In this study, hepatic gene expression profiles of cynomolgus macaques bred in Cambodia (mfCAM), China (mfCHN), and Indonesia (mfIDN) were analyzed. Microarray analysis revealed that expression of most hepatic genes, including drug-metabolizing enzyme genes, was not substantially different between mfCAM, mfCHN, and mfIDN; only 1.1% and 3.0% of all the gene probes detected differential expression (>2.5-fold) in mfCAM compared with mfCHN and mfIDN, respectively. Quantitative polymerase chain reaction showed that the expression levels of 14 cytochromes P450 (P450s) important for drug metabolism did not differ (>2.5-fold) in mfCAM, mfCHN, and mfIDN, validating the microarray data. In contrast, expression of CYP2B6 and CYP3A4 differed (>2.5-fold, p profiles, including drug-metabolizing enzyme genes such as P450 genes, are similar in mfCAM, mfCHN, and mfIDN.

    Full Text Available SETTING: National Tuberculosis Programme, Cambodia. OBJECTIVE: In a cohort of TB patients, to ascertain the proportion of patients who fulfil the criteria for presumptive MDR-TB, assess whether they underwent investigation for MDR-TB, and the results of the culture and drug susceptibility testing (DST. METHODS: A cross sectional record review of TB patients registered for treatment between July-December 2011. RESULTS: Of 19,236 TB patients registered, 409 (2% fulfilled the criteria of presumptive MDR-TB; of these, 187 (46% were examined for culture. This proportion was higher among relapse, failure, return after default (RAD and non-converters at 3 months of new smear positive TB patients (>60% as compared to non-converters at 2 months of new TB cases (<20%. Nearly two thirds (n = 113 of the samples were culture positive; of these, three-fourth (n = 85 grew Mycobacterium tuberculosis complex (MTBc and one-fourth (n = 28 grew non-tuberculous Mycobacteria. DST results were available for 96% of the MTBc isolates. Overall, 21 patients were diagnosed as MDR-TB (all diagnosed among retreatment TB cases and none from non-converters and all of them were initiated on MDR-TB treatment. CONCLUSION: There is a need to strengthen mechanisms for linking patients with presumptive MDR-TB to culture centers. The policy of testing non-converters for culture and DST needs to be reviewed.

    Middle Holocene vegetation and mangrove successions are clearly evident in the palynological records of two cores from the upper Mekong River delta in Cambodia. Spanning from ~ 9.4 to 6.3 cal ka BP, the cores mainly record a transgressive sequence from floodplain freshwater marsh to tidal flat, which was overlain by mangrove. Corresponding to the decelerated sea-level rise at ~ 8.3 cal ka BP, pioneer mangrove species Sonneratia alba and Sonneratia caseolaris appeared in the sediments, and then was replaced by regressive mangrove succession containing upward-increasing abundances of Rhizophora apiculata and Bruguiera spp. High salinity- and flooding-tolerant community S. alba was developed at the western core site PSG at ~ 8.2 cal ka BP, and the eastern core site PK at ~ 7.5 cal ka BP. The time difference of S. alba appearance between the two sites might be resulted from the complexity of sedimentary environment, where a higher sediment supply was provided to the western floodplain than to the eastern floodplain. After 7.5 cal ka BP, aggradational stacking of intertidal sediments, of which the thickness is larger than the present maximum tidal range, may have resulted from continuous sea-level rise during 7.5-7.0 cal ka BP.

    Mental health issues are significant contributors to the global burden of disease with the highest incidence in resource poor countries; 90% of those in need of mental health treatment reside in low resource countries but receive only 10% of the world's resources. Cambodia, the eighth least developed country in the world, serves as one example of the need to address mental health concerns in low-income, resource poor countries. The current study utilises responsive evaluation methodology to explore how poverty-stricken Cambodian clients, therapists and supervisors experience Western models of therapy as culturally responsive to their unique needs. Quantitative and qualitative data were triangulated across multiple stakeholders using numerous methods including a focus group, interviews, surveys, case illustrations and live supervision observation and analysed using constant comparative analysis. Emerging findings suggest that poverty, material needs, therapy location and financial situations greatly impact the daily lives and mental health conditions of Cambodians and hinder clients' therapeutic progress. The local community needs and context of poverty greatly hinder clients' therapeutic progress in therapy treatment and when therapy does not directly address the culture of poverty, clients did not experience therapy as valuable despite some temporary decreases in mental health symptoms.

    Enriched As in drinking water wells in south and Southeast Asia has increased the risk of cancer for nearly 100 million people. This enrichment is generally attributed to the reductive dissolution of Fe oxides; however, the complex expression of As enrichment in these areas is not yet well understood. Here, the coupled sedimentological and geochemical factors that contribute to the extent and spatial distribution of groundwater As concentrations in the Mekong River delta, Cambodia in an avulsed scroll bar sequence are examined. X-Ray absorption spectroscopy (XAS) was used to determine Fe and As speciation in redox preserved sediment collected from drilled cores. Dissolved As, Fe and S solution concentrations in existing and newly drilled wells (cores) differed considerably depending on their source sedimentology. The rapid burial of organic matter in the scroll bar sequence facilitated the development of extensive Fe-reducing conditions, and As release into the aquifer. In older features organic C levels are high enough to sustain extensive Fe reduction and provide ample SO{sub 4} which is reduced to sulfide. This S reduction impacts As levels; As is sequestered in sulfide minerals outside of the scrollbar sequence, decreasing pore water concentrations. In contrast, As is depleted in sediments from the scroll sequence, and associated with elevated pore water aqueous concentrations. The concentration and form of organic C in the scrollbar sequence is related to depositional environment, and can facilitate Fe and S mineral transformations, distinct sedimentary environments explain a portion of the inherent heterogeneity of aquifer As concentrations.

  3. Intergenerational Land Transfer in Rural Cambodia since the Late 1980s: Special Attention to the Effect of Labor Migration

    Full Text Available Using primary data collected from three villages in Prey Veng and Pousat provinces, this study describes how land has been transferred from parents to children in rural Cambodia since the late 1980s. While equal division among all children is the most favored practice—thus further farm fragmentation is anticipated in the near future—parents with very small land endowment are unable to divide land equally among all their children and some children are unable to receive land from their parents. The expansion of migration opportunity has not caused fundamental changes in land transfer practices, but the premarital migration experience of children is negatively associated with land transfer, especially when children settle in the migration destination or marry a person from another province whom they met at the migration destination and move to their partner’s place of origin. The data indicate that, ­taking advantage of labor migration experience, children of land-poor parents choose to leave their home province and make a living without land. However, landless children are in a disadvantaged economic situation because they are also less likely to receive non-land assets from their parents and farmland from their spouse’s parents.

  4. Investors, Managers, Brokers, and Culture Workers: How the "New" Chinese are Changing the Meaning of Chineseness in Cambodia

    Full Text Available China has become the largest source of capital in Cambodia. Managers of state enterprises that construct hydropower plants and roads—as well as private investors and managers in mining, agricultural land concessions, and garment manufacturing—wield increasing influence and are beginning to shape labor practices. In this situation, mainland Chinese migrants are no longer seen by the Sino-Khmer as the marginal and suspect outsiders that they were twenty years ago. Rather, for both the increasingly entrenched Sino-Khmer elite and the struggling Sino-Khmer middle classes, they are a source of business opportunities or jobs. The Sino-Khmer have emerged as middlemen both between Chinese capital and the neopatrimonial Cambodian state and between Chinese managers and Khmer labor. This role is predicated upon a display of Chineseness whose form and content is itself rapidly changing under the influence of an increasing number of teachers and journalists who come from the mainland to run Cambodia’s Chinese-language press and schools. This paper will attempt to makes sense of the facets of this change.

    First documented in 1741, the practice of episiotomy substantially increased worldwide during the 20th century. However, research shows that episiotomy is not effective in reducing severe perineal trauma and may be harmful. Using a mixed-methods approach, we conducted a study in 2013-14 on why obstetricians and midwives in a large maternity hospital in Phnom Penh, Cambodia, still do routine episiotomies. The study included the extent of the practice, based on medical records; a retrospective analysis of the delivery notes of a random sample of 365 patients; and 22 in-depth interviews with obstetricians, midwives and recently delivered women. Of the 365 women, 345 (94.5%, 95% CI: 91.7-96.6) had had an episiotomy. Univariate analysis showed that nulliparous women underwent episiotomy more frequently than multiparous women (OR 7.1, 95% CI 2.0-24.7). The reasons given for this practice by midwives and obstetricians were: fear of perineal tears, the strong belief that Asian women have a shorter and harder perineum than others, lack of time in overcrowded delivery rooms, and the belief that Cambodian women would be able to have a tighter and prettier vagina through this practice. A restrictive episiotomy policy and information for pregnant women about birthing practices through antenatal classes should be implemented as soon as possible.

    A randomized, controlled intervention trial of two household-scale drinking water filters was conducted in a rural village in Cambodia. After collecting four weeks of baseline data on household water quality, diarrheal disease, and other data related to water use and handling practices, households were randomly assigned to one of three groups of 60 households: those receiving a ceramic water purifier (CWP), those receiving a second filter employing an iron-rich ceramic (CWP-Fe), and a control group receiving no intervention. Households were followed for 18 weeks post-baseline with biweekly follow-up. Households using either filter reported significantly less diarrheal disease during the study compared with a control group of households without filters as indicated by longitudinal prevalence ratios CWP: 0.51 (95% confidence interval [CI]: 0.41-0.63); CWP-Fe: 0.58 (95% CI: 0.47-0.71), an effect that was observed in all age groups and both sexes after controlling for clustering within households and within individuals over time.

    Full Text Available Malnutrition is locked in a vicious cycle of increased mortality, poor health, impaired cognitive development, slow physical growth, reduced learning capacity, inferior performance, and ultimately lower adult work performance and productivity. The consensus of global scientific evidence indicates that lowering the rates of malnutrition will be an indispensable component of any successful program to raise the quality of human capital and resources. This study used a “consequence model” to apply the coefficient risk-deficit on economic losses, established in the global scientific literature, to Cambodian health, demographic, and economic data to develop a national estimate of the value of economic losses due to malnutrition. The impact of the indicators of malnutrition analyzed represent a burden to the national economy of Cambodia estimated at 266 million USD annually (1.7% of GDP. Stunting is reducing the Cambodian economic output by more than 120 million USD, and iodine deficiency disorders alone by 57 million USD. This economic burden is too high in view of Cambodia’s efforts to drive economic development. The government should rapidly expand a range of low-cost effective nutrition interventions to break the current cycle of increased mortality, poor health and ultimately lower work performance, productivity, and earnings.

    Full Text Available Organophosphates and carbamates (OPs/CMs are known for their acetylcholinesterase inhibiting character. A cross-sectional study of pesticide handling practices and self-perceived symptoms of acute pesticide poisoning was conducted using questionnaire-based interviews with 89 pesticide sprayers in Boeung Cheung Ek (BCE Lake, Phnom Penh, Cambodia. The study showed that 50% of the pesticides used belonged to WHO class I + II and personal protection among the farmers were inadequate. A majority of the farmers (88% had experienced symptoms of acute pesticide poisoning, and this was significantly associated with the number of hours spent spraying with OPs/CMs (OR = 1.14, CI 95%: 1.02–1.28. The higher educated farmers reduced their risk of poisoning by 55% for each extra personal protective measure they adapted (OR = 0.45, CI 95%: 0.22–0.91. These findings suggest that improving safe pesticide management practices among the farmers and enforcing the effective banning of the most toxic pesticides will considerably reduce the number of acute pesticide poisoning episodes.

Exclusive breastfeeding is reported to be widely practiced in Cambodia, and important progress has been made toward achieving improved child health outcomes, but newborn mortality has been slow to reduce and breastfeeding practices remain suboptimal. Methods: Formative research was conducted in Takeo province, Cambodia to describe the practical, cultural, and social factors underlying current breastfeeding behaviors to inform the design of a newborn survival intervention that may improve breastfeeding. In-depth interviews, observations, a collection of visual media, and focus groups were employed to gather qualitative data. Results: The results revealed knowledge and practice gaps in behavior that likely contribute to breastfeeding barriers, particularly in the areas of infant latch, milk production, feeding frequency, and the use of breast milk substitutes. The predominant theme identified in the research was a dearth of detailed information, advice, and counseling for mothers beyond the message to exclusively breastfeed for 6 months. Conclusion: Future newborn survival interventions and postnatal care counseling in this area must go beyond the exclusive breastfeeding message. To achieve further impact, it will be necessary to disseminate comprehensive and locally appropriate information on breastfeeding and to improve counseling in order to support successful breastfeeding and to contribute to population-level health gains. Keywords: formative research, health education, lactation, behavior change

    Cambodia's first-line artemisinin combination therapy, dihydroartemisinin-piperaquine (DHA-PPQ), is no longer sufficiently curative against multidrug-resistant Plasmodium falciparum malaria at some Thai-Cambodian border regions. We report recent (2008 to 2013) drug resistance trends in 753 isolates from northern, western, and southern Cambodia by surveying for ex vivo drug susceptibility and molecular drug resistance markers to guide the selection of an effective alternative to DHA-PPQ. Over the last 3 study years, PPQ susceptibility declined dramatically (geomean 50% inhibitory concentration [IC50] increased from 12.8 to 29.6 nM), while mefloquine (MQ) sensitivity doubled (67.1 to 26 nM) in northern Cambodia. These changes in drug susceptibility were significantly associated with a decreased prevalence of P. falciparum multidrug resistance 1 gene (Pfmdr1) multiple copy isolates and coincided with the timing of replacing artesunate-mefloquine (AS-MQ) with DHA-PPQ as the first-line therapy. Widespread chloroquine resistance was suggested by all isolates being of the P. falciparum chloroquine resistance transporter gene CVIET haplotype. Nearly all isolates collected from the most recent years had P. falciparum kelch13 mutations, indicative of artemisinin resistance. Ex vivo bioassay measurements of antimalarial activity in plasma indicated 20% of patients recently took antimalarials, and their plasma had activity (median of 49.8 nM DHA equivalents) suggestive of substantial in vivo drug pressure. Overall, our findings suggest DHA-PPQ failures are associated with emerging PPQ resistance in a background of artemisinin resistance. The observed connection between drug policy changes and significant reduction in PPQ susceptibility with mitigation of MQ resistance supports reintroduction of AS-MQ, in conjunction with monitoring of the P. falciparum mdr1 copy number, as a stop-gap measure in areas of DHA-PPQ failure.

    Full Text Available Abstract Background The average annual reported dengue incidence in Cambodia is 3.3/1,000 among children Methods In 2006, active fever surveillance was conducted among a cohort of 6,694 children aged ≤ 15 years in 16 villages in Kampong Cham province, Cambodia. Subsequently, a case-control study was performed by individually assigning one non-dengue febrile control from the cohort to each laboratory-confirmed dengue case. Parents of cases and controls were interviewed using a standardized questionnaire to determine household-level, illness-related expenditures for medical and non-medical costs, and estimated income loss (see Additional file 1. The household socio-economic status was determined and its possible association with health seeking behaviour and the ability to pay for the costs of a febrile illness. Additional File 1 2006 cost study survey questionnaire, Cambodia. the questionnaire represents the data collection instrument that was developed and used during the present study. Click here for file Results Between September and November 2006, a total of 60 household heads were interviewed: 30 with dengue-positive and 30 with dengue-negative febrile children. Mean total dengue-related costs did not differ from those of other febrile illnesses (31.5 vs. 27.2 US$, p = 0.44. Hospitalization almost tripled the costs of dengue (from 14.3 to 40.1 US$ and doubled the costs of other febrile illnesses (from 17.0 to 36.2 US$. To finance the cost of a febrile illness, 67% of households incurred an average debt of 23.5 US$ and higher debt was associated with hospitalization compared to outpatient treatment (US$ 23.1 vs. US$ 4.5, p Conclusion In Cambodia, dengue and other febrile illnesses pose a financial burden to households. A possible reason for a lower rate of hospitalization among children from poor households could be the burden of higher illness-related costs and debts.

    Full Text Available Crematogaster fraxatrix Forel, 1911 and two new species, C. chhangi sp. n. and C. simboloni sp. n., are described from Cambodia and Indonesia, respectively. DNA sequences were generated for C. fraxarix and the two newly described species using 3 amplications of two regions of the mitochondrial gene COI with a total of 1129 bp. The mean interspecific divergences are 9.4 % and 23.5 % for C. fraxatrix vs. C. chhangi, C. simboloni, respectively. DNA sequences reveal that C. simboloni is found to be genetically distinct from the other two species, but C. chhangi is not distinct from C. fraxatrix.

  14. Potential use of school absenteeism record for disease surveillance in developing countries, case study in rural Cambodia.

    Calvin K Y Cheng

    Full Text Available BACKGROUND: Disease surveillance allows prospective monitoring of patterns in disease incidence in the general community, specific institutions (e.g. hospitals, elderly care homes, and other important population subgroups. Surveillance activities are now routinely conducted in many developed countries and in certain easy-to-reach areas of the developing ones. However due to limited health resources, population in rural area that consisted of the most the vulnerable groups are not under surveillance. Cheaper alternative ways for disease surveillance were needed in resource-limited settings. METHODS AND FINDINGS: In this study, a syndromic surveillance system using disease specific absenteeism rates was established in 47 pre-schools with 1,417 students 3-6 y of age in a rural area of Kampot province, Cambodia. School absenteeism data were collected via short message service. Data collected between 1st January and 31st December 2012 was used for system evaluation for future potential use in larger scale. The system appeared to be feasible and acceptable in the rural study setting. Moderate correlation was found between rates of school absenteeism due to illness and the reference data on rates of attendance at health centers in persons <16 y (maximum cross-correlation coefficient = 0.231 at lag = -1 week. CONCLUSIONS: School absenteeism data is pre-existing, easily accessible and requires minimum time and resources after initial development, and our results suggest that this system may be able to provide complementary data for disease surveillance, especially in resource limited settings where there is very little information on illnesses in the community and traditional surveillance systems are difficult to implement. An important next step is to validate the syndromic data with other forms of surveillance including laboratory data.

    In Cambodia, the majority of the population is rural and reliant on subsistence agriculture, with cattle raised by smallholder farmers using traditional practices, resulting in low productivity and vulnerability to foot-and-mouth disease (FMD). As FMD causes deleterious impacts on rural livelihoods, known FMD risk factors were reviewed, using knowledge, attitudes and practice (KAP) surveys of smallholders (n = 240) from four regions. The study aimed to understand current biosecurity threats to smallholder livelihoods and investigate the hypothesis that smallholder farmers practising FMD risk management should be associated with higher incomes from cattle. Descriptive data were examined to demonstrate trends in KAP and a multivariable linear regression model developed to identify cattle income predictors. Results showed that baseline mean knowledge scores were low at 28.4% across all regions and basic biosecurity practices, including quarantine of new cattle, isolation of sick cattle and FMD vaccination, were lacking. As farmers purchase and sell cattle from and to various administration levels (including export), there is high risk of FMD transmission into and from smallholder communities. The final multivariable linear regression model identified significant explanatory parameters for annual cattle income, including region, number of calves born, forage plot size (ha), vaccination of cattle and the number of cattle purchased (F pr. biosecurity practices including FMD vaccination were not significant predictors of income. With the current focus of farmers on treatment of FMD with inappropriate antibiotics leading to potential anti-microbial residue issues, yet receptivity to payment for vaccine in most regions, there is an urgent need for a coordinated national biosecurity and FMD management public awareness campaign. Further, to enhance the association between improved cattle health and rural livelihoods, it is recommended that livestock development programmes

    Full Text Available Abstract Background Malaria continues to be a major public health problem in remote forested areas in Cambodia. As a national strategy to strengthen community-based malaria control, the Cambodian government has been running the Village Malaria Worker (VMW project since 2001. This study sought to examine the nature and quality of the VMWs' services. Methods Data collection was carried out in February and March 2008 through interviews with one of the two VMWs who takes the lead in malaria control activities in each of the 315 VMW villages (n = 251. The questionnaire addressed 1 the sociodemographic characteristics of VMWs, 2 service quality, 3 actions for malaria prevention and vector control, and 4 knowledge of malaria epidemiology and vector ecology. Results VMWs were effective in conducting diagnosis with Rapid Diagnostic Tests (RDTs and prescribing anti-malarials to those who had positive RDT results, skills that they had acquired through their training programmes. However, most other services, such as active detection, explanations about compliance, and follow-up of patients, were carried out by only a small proportion of VMWs. The variety of actions that VMWs took for malaria prevention and vector control was small (average action index score 12.8/23, and their knowledge was very limited with less than 20% of the VMWs giving correct answers to six out of seven questions on malaria epidemiology and vector ecology. Knowledge of vector breeding places and malaria transmission were significant determinants of both the quality of VMWs' services and the variety of their actions for malaria prevention and vector control. Conclusions VMWs' services focused primarily on diagnosis and treatment. Their focus needs to be broadened to cover other aspects of malaria control in order to further strengthen community-based malaria control. VMWs' actions and knowledge also need substantial improvement. Strengthening training programmes can help achieve better

    Artesunate and mefloquine combination treatment has been used since 2000 in Cambodia as the first-line drug for the treatment of uncomplicated falciparum malaria. In order to assess its efficacy and safety, the national malaria control programme conducted 14 therapeutic efficacy studies with the drug combination between 2001 and 2004 at nine sites. In 2001 and 2002, co-blister packs of artesunate and mefloquine were used, whereas in 2003 and 2004, drugs were given individually from a bulk pack at a total dose of 12 mg/kg of artesunate and 25 mg/kg of mefloquine over 3 days. A total of 1025 patients were enrolled over the 4 years and 977 were follow-up during the period of 28 days. The PCR-corrected cure rates ranged from 85.7% to 100% with an overall cure rate of 95.8% (920/960). The studies in 2002 showed also that co-blister packs used on the basis of age and not on the basis of weight could lead to underdosed regimens but without any detectable effect on the treatment outcome. The follow-up period was extended from 28 to 42 days in three sites in 2004. A total of 219 among 255 were follow-up until day 42. The cure rate decreased but not significantly from 90.1% (73/81) with 28 days follow-up to 79.3% (46/58) with 42 days follow-up in Pailin, whereas the cure rate remained at 100% in the two other sites. Side effects were common, especially dizziness, but were mild and transient and patients recovered without any medical intervention.

    Full Text Available Introduction: Foodborne outbreaks are common in Cambodia, but only a few investigations documenting the etiology and source have been conducted. In April, we learnt of 49 acute diarrhoea cases in a village following a wedding banquet. We undertook an investigation to identify the pathogen, source and mode of transmission.Methods: We interviewed banquet hosts and food handlers to obtain the menu and guest list. Guests were asked about signs and symptoms and onset of illness, time of meal and food or drinks consumed. Rectal swabs were taken from 13 cases for culture. A case-control study was undertaken; cases were guests who had acute diarrhoea within three days after the wedding and controls were guests who remained well during the same time period.Results: There were 256 guests. Of 69 interviewees, 52 got sick (attack rate 75%. Aside from diarrhoea, cases had abdominal pain (94%, vomiting (48%, nausea (42% and fever (25%. Incubation periods ranged from seven to 51 hours (median 16.5. Rectal swabs from three cases grew Vibrio parahaemolyticus. Among the food and drinks served, vegetable salad with raw octopus was the only one associated with illness (odds ratio: 6.6, 95% confidence interval: 1.3–36.1, P = 0.01.Discussion: Vegetable salad with raw octopus was the suspected vehicle for transmission of this Vibrio parahaemolyticus enteritis outbreak. Messages regarding the risks from eating raw seafood were disseminated, and food handlers were advised to cook seafood to high temperatures. Efforts to improve foodborne disease surveillance and food safety are being undertaken.

    Significant gaps in immunity to polio, measles, and rubella may exist in adults in Cambodia and threaten vaccine-preventable disease (VPD) elimination and control goals, despite high childhood vaccination coverage. We conducted a nationwide serological survey during November-December 2012 of 2154 women aged 15-39 years to assess immunity to polio, measles, and rubella and to estimate congenital rubella syndrome (CRS) incidence. Measles and rubella antibodies were detected by IgG ELISA and polio antibodies by microneutralization testing. Age-structured catalytic models were fitted to rubella serological data to predict CRS cases. Overall, 29.8% of women lacked immunity to at least one poliovirus (PV); seroprevalence to PV1, PV2 and PV3 was 85.9%, 93.4% and 83.3%, respectively. Rubella and measles antibody seroprevalence was 73.3% and 95.9%, respectively. In the 15-19 years age group, 48.2% [95% confidence interval (CI) 42.4-54.1] were susceptible to either PV1 or PV3, and 40.3% (95% CI 33.0-47.5) to rubella virus. Based on rubella antibody seroprevalence, we estimate that >600 infants are born with CRS in Cambodia annually. Significant numbers of Cambodian women are still susceptible to polio and rubella, especially those aged 15-19 years, emphasizing the need to include adults in VPD surveillance and a potential role for vaccination strategies targeted at adults.

    Full Text Available Abstract Background Borrowing money is a common strategy to cope with health care costs. The impact of borrowing on households can be severe, leading to indebtedness and further impoverishment. However, the available literature on borrowing practices for health is limited. We explore borrowing practices for paying for health care by the poor in Cambodia and provide a typology, associated conditions, and the extent of the phenomenon. Methods In addition to a semi-structured literature review, in-depth interviews were conducted with representatives of 47 households with health-related debt and 19 managers of formal or informal credit schemes. Results A large proportion of Cambodians, especially the poor, resort to borrowing to meet the cost of health care. Because of limited cash flow and access to formal creditors, the majority take out loans with high interest rates from informal money lenders. The most common type of informal credit is locally known as Changkar and consists of five kinds of loans: short-term loans, medium-term loans, seasonal loans, loans for an unspecified period, and loans with repayment in labour, each with different lending and repayment conditions and interest rates. Conclusion This study suggests the importance of informal credit for coping with the cost of treatment and its potentially negative impact on the livelihood of Cambodian people. We provide directions for further studies on financial protection interventions to mitigate harmful borrowing practices to pay for health care in Cambodia.

  1. Considering the Practical Rationality of Experimental Operation in Developing Countries: Reality and Challenges under a Rigid Community Forestry System in Cambodia

    Full Text Available Influential stakeholders have highlighted many constraints inherent in conventional scientific forest management plans for community forestry (CF and presented simpler alternatives. Nevertheless, some developing countries continue to use rigid, complex and high-cost plans and regulations. This article considers two issues: (1 why heavily-regulated or rigid CF systems were originally introduced and why they continue to be used in developing countries despite critiques and counterproposals; and (2 under what circumstances will such CF systems face an impasse, and what can be done to resolve the situation. Using Cambodia as a case study, we examine the development of a rigid CF system, review negative factors influencing the upland forested area, clarify the unfavorable situations arising from these factors and discuss likely problems associated with the CF management system. International organizations played a key role in the introduction and maintenance of rigid, complex and high-cost CF systems in Cambodia. Conflicts and crises arise when the administration prosecutes local farmers for illegal cultivation or deprives communities of CF management rights because of the expansion of commercial crop cultivation and the lack of adequate community management in response to unprecedented changes. A likely practical solution to the probable impasse is the development and funding of a functional network of CF management committees, rather than the adoption of an entirely new, alternative system.

    Recent solar disinfection (SODIS) studies in Bolivia and South Africa have reported compliance rates below 35% resulting in no overall statistically significant benefit associated with disease rates. In this study, we report the results of a 1 year randomized controlled trial investigating the effect of SODIS of drinking water on the incidence of dysentery and nondysentery diarrhea among children of age 6 months to 5 years living in rural communities in Cambodia. We compared 426 children in 375 households using SODIS with 502 children in 407 households with no intervention. Study compliance was greater than 90% with only 5% of children having less than 10 months of follow-up and 2.3% having less than 6 months. Adjusted for water source type, children in the SODIS group had a reduced incidence of dysentery, with an incidence rate ratio (IRR) of 0.50 (95% CI 0.27-0.93, p = 0.029). SODIS also had a protective effect against nondysentery diarrhea, with an IRR of 0.37 (95% CI 0.29-0.48, p SODIS is an effective and culturally acceptable point-of-use water treatment method in the culture of rural Cambodia and may be of benefit among similar communities in neighboring South East Asian countries.

    To precisely visualize the Royal City of Angkor Thom, Cambodia, we used a new method in field of cultural heritage study. Read Relief Image Map (RRIM, Chiba et al., 2008) is a powerful method which has been used for geomorphological studies. In this study, using the LiDAR data conducted at the Angkor Archaeological Park in Cambodia in April 2012 (Evans et al., 2013), we visualized the Royal City of Angkor Thom and its vicinity (Shimoda et al., 2016). The RRIM provided a new visualization method of localizing, minute topographical changes in regions with large undulations over a wide area. It has proved to be effective in mapping, on a single wide-area map, the numerous buried remains that exist as comparable height differences or minute undulations measuring less than 1 meter in height, and provides a unique aerial view of their widespread distribution. Based on the RRIM map, past archaeological studies were referenced to reconstruct the layout of the water channel network system. Past studies revealed that a large number of ponds had been dug inside Angkor Thom. The RRIM expanded the investigation and revealed the existence of many ponds outside the royal capital indicating that a residential community had flourished outside the moat surrounded capital city.

    Full Text Available User-friendly, accurate, point-of-care rapid tests to detect glucose-6-phosphate dehydrogenase deficiency (G6PDd are urgently needed at peripheral level to safely recommend primaquine for malaria elimination.The CareStart G6PD RDT (AccessBio, New Jersey, USA, a novel rapid diagnostic test and the most commonly used test, the fluorescent spot test (FST were assessed against the quantitatively measured G6PD enzyme activity for detecting G6PDd. Subjects were healthy males and non-pregnant females aged 18 years or older residing in six villages in Pailin Province, western Cambodia.Of the 938 subjects recruited, 74 (7.9% were severe and moderately severe G6PD deficient (enzyme activity <30%, mostly in male population; population median G6PD activity was 12.0 UI/g Hb. The performances of the CareStart G6PD RDT and the FST, according to different cut-off values used to define G6PDd were very similar. For the detection of severe and moderately severe G6PDd (enzyme activity < 30%, < 3.6 UI/g Hb in males and females, sensitivity and negative (normal status predictive value were 100% for both point-of-care tools. When the G6PDd cut-off value increased (from < 40% to < 60%, the sensitivity for both PoCs decreased: 93.3% to 71.7% (CareStart G6PD RDT, p = 10(-6 and 95.5% to 73.2% (FST, p = 10(-6 while the specificity for both PoCs remained similar: 97.4% to 98.3% (CareStart G6PD RDT, p = 0.23 and 98.7% to 99.6% (FST, p = 0.06. The cut-off values for classifying individuals as normal were 4.0 UI/g Hb and 4.3 UI/g Hb for the CareStart G6PD RDT and the FST, respectively.The CareStart G6PD RDT reliably detected moderate and severe G6PD deficient individuals (enzyme activity <30%, suggesting that this novel point-of-care is a promising tool for tailoring appropriate primaquine treatment for malaria elimination by excluding individuals with severe G6PDd for primaquine treatment.

    Full Text Available In light of the limitations of the current case finding strategies and the global urgency to improve tuberculosis (TB case-detection, a renewed interest in active case finding (ACF has risen. The WHO calls for more evidence on innovative ways of TB screening, especially from low-income countries, to inform global guideline development. We aimed to assess the feasibility of community-based ACF for TB among the urban poor in Cambodia and determine its impact on case detection, treatment uptake and outcome.Between 9/2/2012-31/3/2013 the Sihanouk Hospital Center of HOPE conducted a door-to-door survey for TB in deprived communities of Phnom Penh. TB workers and community health volunteers performed symptom screening, collected sputum and facilitated specimen transport to the laboratories. Fluorescence microscopy was introduced at three referral hospitals. The GeneXpert MTB/RIF assay (Xpert was performed at tertiary level for individuals at increased risk of HIV-associated, drug-resistant or smear-negative TB. Mobile phone/short message system (SMS was used for same-day issuing of positive results. TB workers contacted diagnosed patients and referred them for care at their local health centre.In 14 months, we screened 315.874 individuals; we identified 12.201 aged ≥ 15 years with symptoms suggestive of TB; 84% provided sputum. We diagnosed 783, including 737 bacteriologically confirmed, TB cases. Xpert testing yielded 41% and 48% additional diagnoses among presumptive HIV-associated and multidrug-resistant TB cases, respectively. The median time from sputum collection to notification (by SMS of the first positive (microscopy or Xpert result was 3 days (IQR 2-6. Over 94% commenced TB treatment and 81% successfully completed it.Our findings suggest that among the urban poor ACF for TB, using a sensitive symptom screen followed by smear-microscopy and targeted Xpert, contributed to improved case detection of drug-susceptible and drug-resistant TB

    Full Text Available Tenure rights over land, forest, and carbon have become a contentious issue within REDD+ implementation across the tropics because local communities could be excluded from REDD+ benefits if land tenure or use and access rights are not clear. This study aims to understand and assess tenure arrangements under the first REDD+ demonstration project in Cambodia, the Oddar Meanchey Com- munity Forestry REDD+ Project. In particular, the study explores the following questions: (1 How are tenure rights arranged in the Oddar Meanchey REDD+ Project? (2 Does the tenure regime recognise the rights of local communities to their land and its associated resources? (3 What kind of institu- tions are put in place to support tenure rights of local communities in the project? The author conducted in-depth semi-structured interviews with key stakeholders and complemented the analysis by participant observation and a review of policy documents and secondary literature. The major finding of this study is that the local communities in the project are still given rights to use and access forest resources, although carbon rights belong to the government. While the government retains ownership over carbon credits, it agreed that at least 50 percent of the net revenue from the sale of carbon credits will flow to participating communities. ------ Besitzrechte an Land, Wald und CO2 sind zu einer umkämpften Angelegenheit in der REDD+ Implementierung in den Tropen geworden.

    Full Text Available Abstract Background Although cervical cancer is the leading cancer in Cambodia, most women receive no routine screening for cervical cancer and few treatment options exist. Moreover, nothing is known regarding the prevalence of cervical HPV or the genotypes present among women in the country. Young sexually active women, especially those with multiple sex partners are at highest risk of HPV infection. We examine the prevalence and genotypes of cervical HPV, as well as the associated risk factors among young women engaged in sex work in Phnom Penh, Cambodia. Methods We conducted a cross-sectional study among 220 young women (15–29 years engaged in sex work in different venues including brothels or entertainment establishments, and on a freelance basis in streets, parks and private apartments. Cervical specimens were collected using standard cytobrush technique. HPV DNA was tested for by polymerase chain reaction (PCR and genotyping using type-specific probes for 29 individual HPV types, as well as for a mixture of 10 less common HPV types. All participants were also screened for HIV status using blood samples. Multivariate logistic regression analyses were conducted to assess risk factors for any or multiple HPV infection. Results The prevalence of cervical HPV 41.1%. HPV 51 and 70 were the most common (5.0%, followed by 16 (4.6%, 71 (4.1% and 81 (3.7%. Thirty-six women (16.4% were infected with multiple genotypes and 23.3% were infected with at least one oncogenic HPV type. In multivariate analyses, having HIV infection and a higher number of sexual partners were associated with cervical HPV infection. Risk factors for infection with multiple genotypes included working as freelance female sex workers (FSW or in brothels, recent binge use of drugs, high number of sexual partners, and HIV infection. Conclusions This is the first Cambodian study on cervical HPV prevalence and genotypes. We found that HPV infection was common among young FSW

    Full Text Available Abstract Background Appropriate case management of suspected malaria in Cambodia is critical given anti-malarial drug resistance in the region. Improving diagnosis and the use of recommended malarial treatments is a challenge in Cambodia where self-treatment and usage of drug cocktails is widespread, a notable difference from malaria treatment seeking in other countries. This qualitative study adds to the limited evidence base on Cambodian practices, aiming to understand the demand-side factors influencing treatment-seeking behaviour, including the types of home treatments, perceptions of cocktail medicines and reasons for diagnostic testing. The findings may help guide intervention design. Methods The study used in-depth interviews (IDIs (N = 16 and focus group discussions (FGDs (N = 12 with Cambodian adults from malaria-endemic areas who had experienced malaria fever in the previous two weeks. Data were analysed using NVivo software. Results Findings suggest that Cambodians initially treat suspected malaria at home with home remedies and traditional medicines. When seeking treatment outside the home, respondents frequently reported receiving a cocktail of medicines from trusted providers. Cocktails are perceived as less expensive and more effective than full-course, pre-packaged medicines. Barriers to diagnostic testing include a belief in the ability to self-diagnose based on symptoms, cost and reliance on providers to recommend a test. Factors that facilitate testing include recommendation by trusted providers and a belief that anti-malarial treatment for illnesses other than malaria can be harmful. Conclusions Treatment-seeking behaviour for malaria in Cambodia is complex, driven by cultural norms, practicalities and episode-related factors. Effective malaria treatment programmes will benefit from interventions and communication materials that leverage these demand-side factors, promoting prompt visits to facilities for suspected

    Full Text Available PURPOSE: Identify epilepsy-associated factors and calculate measures of impact, stigma, quality of life (QOL, knowledge-attitude-practice (KAP and treatment gap in Prey Veng, Cambodia. METHODS: This first Cambodian population-based case-control study had 96 epileptologist-confirmed epilepsy cases and 192 randomly selected matched healthy controls. Standard questionnaires, which have been used in similar settings, were used for collecting data on various parameters. Univariate and multivariate regression was done to determine odds ratios. Jacoby stigma, 31-item QOL, KAP etc were determined and so were the factors associated with them using STATA software. Treatment gap was measured using direct method. KEY FINDINGS: Multivariate analyses yielded family history of epilepsy, difficult or long delivery, other problems beside seizures (mainly mental retardation, hyperthermia, and eventful pregnancy of the subject's mother as factors associated with epilepsy. There was high frequency of seizure precipitants esp. those related to sleep. Population attributable risk (% was: family history (15.0, eventful pregnancy of subject's mother (14.5, long/difficult birth (6.5, and other problem beside seizures (20.0. Mean stigma (1.9±1.1, on a scale of 3 was mainly related to treatment efficacy. Mean QOL (5.0±1.4 on a scale of 10 was mainly related to treatment regularity. Cause or risk factor could be determined in 56% of cases. Treatment gap was 65.8%. SIGNIFICANCE: Factors in pre- and perinatal period were found to be most crucial for epilepsy risk in Cambodia which inturn provides major prevention opportunities. A global action plan for treatment, stigma reduction and improvement of QOL should be set-up in this country.

    Human enterovirus 71 (EV-A71) causes hand, foot and mouth disease (HFMD). EV-A71 circulates in many countries and has caused large epidemics, especially in the Asia-Pacific region, since 1997. In April 2012, an undiagnosed fatal disease with neurological involvement and respiratory distress occurred in young children admitted to the Kantha Bopha Children's Hospital in Phnom Penh, Cambodia. Most died within a day of hospital admission, causing public panic and international concern. In this study, we describe the enterovirus (EV) genotypes that were isolated during the outbreak in 2012 and the following year. From June 2012 to November 2013, 312 specimens were collected from hospitalized and ambulatory patients and tested by generic EV and specific EV-A71 reverse transcription PCR. EV-A71 was detected in 208 clinical specimens while other EVs were found in 32 patients. The VP1 gene and/or the complete genome were generated. Our phylogenetic sequencing analysis demonstrated that 80 EV-A71 strains belonged to the C4a subgenotype and 3 EV-A71 strains belonged to the B5 genotype. Furthermore, some lineages of EV-A71 were found to have appeared in Cambodia following separate introductions from neighboring countries. Nineteen EV A (CV-A6 and CV-A16), 9 EV B (EV-B83, CV-B3, CV-B2, CV-A9, E-31, E-2 and EV-B80) and 4 EV C (EV-C116, EV-C96, CV-A20 and Vaccine-related PV-3) strains were also detected. We found no molecular markers of disease severity. We report here that EV-A71 genotype C4 was the main etiological agent of a large outbreak of HFMD and particularly of severe forms associated with central nervous system infections. The role played by other EVs in the epidemic could not be clearly established.

    The potential impacts of payments for environmental services (PES) and protected areas (PAs) on environmental outcomes and local livelihoods in developing countries are contentious and have been widely debated. The available evidence is sparse, with few rigorous evaluations of the environmental and social impacts of PAs and particularly of PES. We measured the impacts on forests and human well-being of three different PES programs instituted within two PAs in northern Cambodia, using a panel of intervention villages and matched controls. Both PES and PAs delivered additional environmental outcomes relative to the counterfactual: reducing deforestation rates significantly relative to controls. PAs increased security of access to land and forest resources for local households, benefiting forest resource users but restricting households’ ability to expand and diversify their agriculture. The impacts of PES on household well-being were related to the magnitude of the payments provided. The two higher paying market-linked PES programs had significant positive impacts, whereas a lower paying program that targeted biodiversity protection had no detectable effect on livelihoods, despite its positive environmental outcomes. Households that signed up for the higher paying PES programs, however, typically needed more capital assets; hence, they were less poor and more food secure than other villagers. Therefore, whereas the impacts of PAs on household well-being were limited overall and varied between livelihood strategies, the PES programs had significant positive impacts on livelihoods for those that could afford to participate. Our results are consistent with theories that PES, when designed appropriately, can be a powerful new tool for delivering conservation goals whilst benefiting local people.

    Full Text Available INTRODUCTION: In resource limited settings, patients entering an antiretroviral therapy (ART program comprise ART naive and ART pre-treated patients who may show differential virological outcomes. METHODS: This retrospective study, conducted in 2010-2012 in the HIV clinic of Calmette Hospital located in Phnom Penh (Cambodia assessed virological failure (VF rates and patterns of drug resistance of naive and pre-treated patients. Naive and ART pre-treated patients were included when a Viral Load (VL was performed during the first year of ART for naive subjects or at the first consultation for pre-treated individuals. Patients showing Virological failure (VF (>1,000 copies/ml underwent HIV DR genotyping testing. Interpretation of drug resistance mutations was done according to 2013 version 23 ANRS algorithms. RESULTS: On a total of 209 patients, 164 (78.4% were naive and 45 (21.5% were ART pre-treated. Their median initial CD4 counts were 74 cells/mm3 (IQR: 30-194 and 279 cells/mm3 (IQR: 103-455 (p<0.001, respectively. Twenty seven patients (12.9% exhibited VF (95% CI: 8.6-18.2%, including 10 naive (10/164, 6.0% and 17 pre-treated (17/45, 37.8% patients (p<0.001. Among these viremic patients, twenty-two (81.4% were sequenced in reverse transcriptase and protease coding regions. Overall, 19 (86.3% harbored ≥1 drug resistance mutations (DRMs whereas 3 (all belonging to pre-treated patients harbored wild-types viruses. The most frequent DRMs were M184V (86.3%, K103N (45.5% and thymidine analog mutations (TAMs (40.9%. Two (13.3% pre-treated patients harbored viruses that showed a multi-nucleos(tide resistance including Q151M, K65R, E33A/D, E44A/D mutations. CONCLUSION: In Cambodia, VF rates were low for naive patients but the emergence of DRMs to NNRTI and 3TC occurred relatively quickly in this subgroup. In pre-treated patients, VF rates were much higher and TAMs were relatively common. HIV genotypic assays before ART initiation and for ART pre

    Collection of surveillance data is essential for monitoring and evaluation of public health programs. Integrated collection of household-based health data, now routinely carried out in many countries through demographic health surveys and multiple indicator surveys, provides critical measures of progress in health delivery. In contrast, biomarker surveys typically focus on single or related measures of malaria infection, HIV status, vaccination coverage, or immunity status for vaccine-preventable diseases (VPD). Here we describe an integrated biomarker survey based on use of a multiplex bead assay (MBA) to simultaneously measure antibody responses to multiple parasitic diseases of public health importance as part of a VPD serological survey in Cambodia. A nationally-representative cluster-based survey was used to collect serum samples from women of child-bearing age. Samples were tested by MBA for immunoglobulin G antibodies recognizing recombinant antigens from Plasmodium falciparum and P. vivax, Wuchereria bancrofti, Toxoplasma gondii, Taenia solium, and Strongyloides stercoralis. Serologic IgG antibody results were useful both for generating national prevalence estimates for the parasitic diseases of interest and for confirming the highly focal distributions of some of these infections. Integrated surveys offer an opportunity to systematically assess the status of multiple public health programs and measure progress toward Millennium Development Goals. PMID:27136913

    As the first record of the Cambodian termitophilous rove beetles, eight new species of the genus Discoxenus Wasmann, 1904 (Aleocharini: Compactopediina) are described, along with a redescription of the genus. Discoxenus katayamai Kanao & Maruyama, 2010, which was originally known from Thailand, is newly recorded from Cambodia and redescribed. Discoxenus species are morphologically divided into two species groups, namely the latiabdominalis and the assmuthi. The latiabdominalis species group includes D. latiabdominalis n. sp. and D. cambodiensis n. sp., and both species are associated with Odontotermes maesodensis Ahmad, 1965. The assmuthi species group comprises 11 species: D. assmuthi Wasmann, 1904, D. lepisma Wasmann, 1904, D. indicus Kistner, 1982, D. malaysiensis Kistner, 1982, D. phourini n. sp., D. kohkongensis n. sp., D. hirsutus n. sp., D. minutus n. sp., D. lucidus n. sp., D. kakizoei n. sp., and D. katayamai. The members in the assmuthi species group are associated with Odontotermes or Hypotermes termites. One of the unique morphological features of the assmuthi species group is the strongly developed distal crest of the male aedeagal median lobe while that observed in the latiabdominalis species group is not produced, which is general character state in the tribe Aleocharini. The character state of distal crest and several other morphological features such as mouthparts are considered to support the monophyly of respective species groups in Discoxenus.

    We developed a soil-vegetation-atmosphere transfer (SVAT) model applicable to simulating CO2 and H2O fluxes from the canopies of rubber plantations, which are characterized by distinct canopy clumping produced by regular spacing of plantation trees. Rubber (Hevea brasiliensis Müll. Arg.) plantations, which are rapidly expanding into both climatically optimal and sub-optimal environments throughout mainland Southeast Asia, potentially change the partitioning of water, energy, and carbon at multiple scales, compared with traditional land covers it is replacing. Describing the biosphere-atmosphere exchange in rubber plantations via SVAT modeling is therefore essential to understanding the impacts on environmental processes. The regular spacing of plantation trees creates a peculiar canopy structure that is not well represented in most SVAT models, which generally assumes a non-uniform spacing of vegetation. Herein we develop a SVAT model applicable to rubber plantation and an evaluation method for its canopy structure, and examine how the peculiar canopy structure of rubber plantations affects canopy CO2 and H2O exchanges. Model results are compared with measurements collected at a field site in central Cambodia. Our findings suggest that it is crucial to account for intensive canopy clumping in order to reproduce observed rubber plantation fluxes. These results suggest a potentially optimal spacing of rubber trees to produce high productivity and water use efficiency.

    Abstract National legislation and global guidance address labelling of complementary foods to ensure that labels support optimal infant and young child feeding practices. This cross‐sectional study assessed the labels of commercially produced complementary foods (CPCF) sold in Phnom Penh (n = 70), Cambodia; Kathmandu Valley (n = 22), Nepal; Dakar Department (n = 84), Senegal; and Dar es Salaam (n = 26), Tanzania. Between 3.6% and 30% of products did not provide any age recommendation and 8.6−20.2% of products, from all sites, recommended an age of introduction of language encouraging exclusive breastfeeding, and almost none (0.0−2.9%) provided accurate and complete messages regarding the appropriate introduction of complementary foods together with continued breastfeeding. Between 34.3% and 70.2% of CPCF manufacturers also produced breastmilk substitutes and 41.7−78.0% of relevant CPCF products cross‐promoted their breastmilk substitutes products. Labelling practices of CPCF included in this study do not fully comply with international guidance on their promotion and selected aspects of national legislation, and there is a need for more detailed normative guidance on certain promotion practices in order to protect and promote optimal infant and young child feeding.

    Current data indicate that under conditions of poverty, tobacco is consumed at the expense of basic needs. In a large national sample from Cambodia, we sought to determine whether tobacco consumption declines under extreme conditions of no income and malnutrition. Our major findings are as follows: (1) Among men, there was no significant difference in the number of cigarettes smoked for no income (425, 95% confidence interval [CI] = 395-456) versus >US$2 per day (442, 95% CI = 407-477); (2) among women, there was no significant difference in the amount of loose tobacco (ie, betel quid) consumed for no income (539 g, 95% CI = 441-637) versus >US$2 per day (558 g, 95% CI = 143-973); (3) for the contrast of no income + malnutrition versus >US$2 per day + no malnutrition in a linear model, there was no significant difference for men who smoked (462 vs 517 cigarettes/month, P = .82) or women who chewed (316 vs 404 g tobacco/month, P = .34), adjusting for confounders. Among the poorest and malnourished Cambodian adults, lack of resources did not appear to prevent them from obtaining smoked or smokeless tobacco.

    A retrospective study was performed to determine the incidence of HIV seroconversion among repeat consultants attending the voluntary testing and counselling centre of the Institut Pasteur of Cambodia as well as factors associated with HIV seroconversion. From 1996 to 1999, 5541 repeat consultants were selected for the study. Exclusion criteria included being aged under 15 years, having initially tested positive or inconclusive and a time span of fewer than 30 days since the last test. In all, 276 persons had seroconverted to HIV, giving an incidence rate of 5.56 per 100 person-years. The seroconversion rate declined from 8.46% in 1996, to 3.06% in 1999 (chi 2 test for trend, p = 10(-5)). Among the risk factors analysed, 3 were significantly associated with lack of seroconversion: being a student (RR = 0.53, p = 0.032) or a civil servant (RR = 0.63, p = 0.012) and systematic condom use with causal partners (RR = 0.37, p = 10(-5)). The decline of HIV seroconversion among repeat consultants attending the VCT centre over the study period may reflect changes in risk behaviour and the beneficial impact of counselling.

    Full Text Available Abstract Background HIV/AIDS treatment programs are currently being mounted in many developing nations that include palliative care services. While measures of palliative care have been developed and validated for resource rich settings, very little work exists to support an understanding of measurement for Africa, Latin America or Asia. Methods This study investigates the construct validity of measures of reported pain, pain control, symptoms and symptom control in areas with high HIV-infected prevalence in Dominican Republic and Cambodia Measures were adapted from the POS (Palliative Outcome Scale. Households were selected through purposive sampling from networks of people living with HIV/AIDS. Consistencies in patterns in the data were tested used Chi Square and Mantel Haenszel tests. Results The sample persons who reported chronic illness were much more likely to report pain and symptoms compared to those not chronically ill. When controlling for the degrees of pain, pain control did not differ between the chronically ill and non-chronically ill using a Mantel Haenszel test in both countries. Similar results were found for reported symptoms and symptom control for the Dominican Republic. These findings broadly support the construct validity of an adapted version of the POS in these two less developed countries. Conclusion The results of the study suggest that the selected measures can usefully be incorporated into population-based surveys and evaluation tools needed to monitor palliative care and used in settings with high HIV/AIDS prevalence.

    2016-09-01

    A multi-phased study was conducted in Cambodia from 2005-2011 to measure the impact of larviciding with the bacterial larvicide, Bacillus thuringiensis israelensis (Bti), a water dispersible granule (WG) formulation on the vector, Aedes aegypti (L.) and the epidemiology. In our studies, all in-use containers were treated at 8 g/1000 L, including smaller containers and animal feeders which were found to contribute 23% of Ae aegypti pupae. The treated waters were subjected to routine water exchange activities. Pupal production was suppressed by an average 91% for 8 weeks. Pupal numbers continued to remain significantly lower than the untreated commune (UTC) for 13 weeks post treatment in the peak dengue vector season (p50% of the household in the UTC harbored ≥11 mosquitoes per home. The adult population continued to remain at significantly much lower numbers in the Bti treated commune than in the UTC for 10-12 weeks post treatment (p<0.05). In 2011, a pilot operational program was evaluated in Kandal Province, a temephos resistant site. It was concluded that 2 cycles of Bti treatment in the 6 months monsoon season with complete coverage of the target districts achieved an overall dengue case reduction of 48% in the 6 treated districts compared to the previous year, 2010. Five untreated districts in the same province had an overwhelming increase of 352% of dengue cases during the same period of time. The larvicide efficacy, treatment of all in-use containers at the start of the monsoon season, together with treatment coverage of entire districts interrupted disease transmission in the temephos resistant province.

    Full Text Available Emerging antimalarial drug resistance in mobile populations remains a significant public health concern. We compared two regimens of dihydroartemisinin-piperaquine in military and civilians on the Thai-Cambodian border to evaluate national treatment policy.Efficacy and safety of two and three-day regimens of dihydroartemisinin-piperaquine were compared as a nested open-label evaluation within a malaria cohort study in 222 otherwise healthy volunteers (18% malaria-infected at baseline. The first 80 volunteers with slide-confirmed Plasmodium falciparum or vivax malaria were randomized 1:1 to receive either regimen (total dose 360 mg dihydroartemisinin and 2880 mg piperaquine and followed weekly for up to 6 months. The primary endpoint was malaria recurrence by day 42. Volunteers with vivax infection received primaquine at study discharge with six months follow-up.Eighty patients (60 vivax, 15 falciparum, and 5 mixed were randomized to dihydroartemisinin-piperaquine. Intention-to-treat all-species efficacy at Day 42 was 85% for the two-day regimen (95% CI 69-94 and 90% for the three-day regimen (95% CI 75-97. PCR-adjusted falciparum efficacy was 75% in both groups with nearly half (45% still parasitemic at Day 3. Plasma piperaquine levels were comparable to prior published reports, but on the day of recrudescence were below measurable in vitro piperaquine IC50 levels in all falciparum treatment failures.In the brief period since introduction of dihydroartemisinin-piperaquine, there is early evidence suggesting declining efficacy relative to previous reports. Parasite IC50 levels in excess of plasma piperaquine levels seen only in treatment failures raises concern for clinically significant piperaquine resistance in Cambodia. These findings warrant improved monitoring of clinical outcomes and follow-up, given few available alternative drugs.ClinicalTrials.gov NCT01280162.

    Full Text Available While community-based active case finding (ACF for tuberculosis (TB holds promise for increasing early case detection among hard-to-reach populations, limited data exist on the acceptability of active screening. We aimed to identify barriers and explore facilitators on the pathway from diagnosis to care among TB patients and health providers.Mixed-methods study. We administered a survey questionnaire to, and performed in-depth interviews with, TB patients identified through ACF from poor urban settlements in Phnom Penh, Cambodia. Additionally, we conducted focus group discussions and in-depth interviews with community and public health providers involved in ACF, respectively.Acceptance of home TB screening was strong among key stakeholders due to perceived reductions in access barriers and in direct and indirect patient costs. Privacy and stigma were not an issue. To build trust and facilitate communication, the participation of community representatives alongside health workers was preferred. Most health providers saw ACF as complementary to existing TB services; however, additional workload as a result of ACF was perceived as straining operating capacity at public sector sites. Proximity to a health facility and disease severity were the strongest determinants of prompt care-seeking. The main reasons reported for delays in treatment-seeking were non-acceptance of diagnosis, high indirect costs related to lost income/productivity and transportation expenses, and anticipated side-effects from TB drugs.TB patients and health providers considered home-based ACF complementary to facility-based TB screening. Strong engagement with community representatives was believed critical in gaining access to high risk communities. The main barriers to prompt treatment uptake in ACF were refusal of diagnosis, high indirect costs, and anticipated treatment side-effects. A patient-centred approach and community involvement were essential in mitigating barriers

    Full Text Available Abstract Background Increasing urbanization and population density, and persisting inequities in health outcomes across socioeconomic groupings have raised concerns internationally regarding the health of the urban poor. These concerns are also evident in Cambodia, which prompted the design of a study to identify and describe the main barriers to access to health services by the poor in the capital city, Phnom Penh. Sources and Methods Main sources of data were through a household survey, followed by in-depth qualitative interviews with mothers, local authorities and health centre workers in four very poor communities in Phnom Penh. Main findings Despite low incomes and education levels, the study communities have moderate levels of access to services for curative and preventive care. However, qualitative findings demonstrate that households contextualize poor health and health access in terms of their daily living conditions, particularly in relation to environmental conditions and social insecurity. The interactions of low education, poor living conditions and high food costs in the context of low and irregular incomes reinforce a pattern of “living from moment to moment” and results in a cycle of disadvantage and ill health in these communities. There were three main factors that put poor communities at a health disadvantage; these are the everyday living conditions of communities, social and economic inequality and the extent to which a society assesses and acts on inequities in their health care access. Conclusions In order to improve access to health and health services for the urban poor, expansion of public health functions and capacities will be required, including building partnerships between health providers, municipal authorities and civil society.

    Fortified rice holds great potential for bringing essential micronutrients to a large part of the world population. The present study quantified the losses of three different micronutrients (vitamin A, iron, zinc) in fortified rice that were produced using three different techniques (hot extrusion, cold extrusion, and coating) and stored at two different environments (25 ± 5 °C at a humidity of 60% and 40 ± 5 °C at a humidity of 75%) for up to one year. Fortified rice premix from the different techniques was mixed with normal rice in a 1:100 ratio. Each sample was analyzed in triplicate. The study confirmed the high stability of iron and zinc during storage while the retention of vitamin A was significantly affected by storage and the type of techniques used to make rice premix. Losses for iron and zinc were typically rice premix. After 12 months at mild conditions (25 °C and humidity of 60%), losses for vitamin A ranged from 20% for cold extrusion, 30% for hot extruded rice 77% for coated rice premix. At higher temperatures and humidity, losses of vitamin A were 40%-50% for extruded premix and 93% for coated premix after 6 months. We conclude that storage does lead to a major loss of vitamin A and question whether rice is a suitable food vehicle to fortify with vitamin A. For Cambodia, fortification of rice with iron and zinc could be an effective strategy to improve the micronutrient status of the population if no other food vehicles are available.

    Reaching out to the poor and the informal sector is a major challenge for achieving universal coverage in lesser-developed countries. In Cambodia, extensive coverage by health equity funds for the poor has created the opportunity to consolidate various non-government health financing schemes under the government's proposed social health protection structure. This paper identifies the main policy and operational challenges to strengthening existing arrangements for the poor and the informal sector, and considers policy options to address these barriers. Conducted in conjunction with the Cambodian Ministry of Health in 2011-12, the study reviewed policy documents and collected qualitative data through 18 semi-structured key informant interviews with government, non-government and donor officials. Data were analysed using the Organizational Assessment for Improving and Strengthening Health Financing conceptual framework. We found that a significant shortfall related to institutional, organisational and health financing issues resulted in fragmentation and constrained the implementation of social health protection schemes, including health equity funds, community-based health insurance, vouchers and others. Key documents proposed the establishment of a national structure for the unification of the informal-sector schemes but left unresolved issues related to structure, institutional capacity and the third-party status of the national agency. This study adds to the evidence base on appropriate and effective institutional and organizational arrangements for social health protection in the informal sector in developing countries. Among the key lessons are: the need to expand the fiscal space for health care; a commitment to equity; specific measures to protect the poor; building national capacity for administration of universal coverage; and working within the specific national context.

    A multi-phased study was conducted in Cambodia from 2005–2011 to measure the impact of larviciding with the bacterial larvicide, Bacillus thuringiensis israelensis (Bti), a water dispersible granule (WG) formulation on the vector, Aedes aegypti (L.) and the epidemiology. In our studies, all in-use containers were treated at 8 g/1000 L, including smaller containers and animal feeders which were found to contribute 23% of Ae aegypti pupae. The treated waters were subjected to routine water exchange activities. Pupal production was suppressed by an average 91% for 8 weeks. Pupal numbers continued to remain significantly lower than the untreated commune (UTC) for 13 weeks post treatment in the peak dengue vector season (p50% of the household in the UTC harbored ≥11 mosquitoes per home. The adult population continued to remain at significantly much lower numbers in the Bti treated commune than in the UTC for 10–12 weeks post treatment (p<0.05). In 2011, a pilot operational program was evaluated in Kandal Province, a temephos resistant site. It was concluded that 2 cycles of Bti treatment in the 6 months monsoon season with complete coverage of the target districts achieved an overall dengue case reduction of 48% in the 6 treated districts compared to the previous year, 2010. Five untreated districts in the same province had an overwhelming increase of 352% of dengue cases during the same period of time. The larvicide efficacy, treatment of all in-use containers at the start of the monsoon season, together with treatment coverage of entire districts interrupted disease transmission in the temephos resistant province.

    While climate change is confirmed to have serious impacts on agricultural production in many regions worldwide, researchers have proposed various measures that farmers can apply to cope with and adapt to those changes. However, it is often the case that not every adaptation measure would be practical and adoptable in a specific region. Farmers may have their own ways of managing and adapting to climate change that need to be taken into account when considering interventions. This study aimed to engage with farmers to: (1) better understand small-holder knowledge, attitudes and practices in relation to perceived or expected climate change; and (2) document cropping practices, climate change perceptions, constraints to crop production, and coping and adaptation options with existing climate variability and expected climate change. This study was conducted in 2015 in Sala Krau village near Pailin (12°52'N, 102°45'E) and Samlout (12°39'N, 102°36'E) of North-West Cambodia. The methods used were a combination of focus group discussions and one-on-one interviews where 132 farming households were randomly selected. We found that farmers were conscious of changes in climate over recent years, and had a good understanding of likely future changes. While farmers are aware of some practices that can be modified to minimize risk and cope with anticipated changes, they are reluctant to apply them. Furthermore; there are no government agricultural extension services provided at the village level and farmers have relied on each other and other actors in the value chain network for information to support their decision-making. There is a lack of knowledge of the principles of conservation agriculture that urgently require agricultural extension services in the region to build farmer ability to better cope and adapt to climate change.

    A potential study in FY 1998 was made of the energy/environment related activity implementation joint (COP3 related AIJ) in 6 Southeast Asian countries. Vietnam is a country which is the lowest in greenhouse effect gas (GHG) emission in the world, but they want the international assistance for their continued development and contribution to the global environment. Laos has to continue their economic development for extermination of poverty and improvement of life level. Accordingly, AIJ has to be the one that supports those and is helpful for both industrial development and environmental improvement. The same in Cambodia as in Laos, AIJ has to be the one that is helpful for both industrial development and promotion of environmental improvement. In Myanmar, GHG emits (CO2 conversion) 94.5% in the agricultural sector where methane is emitted from livestock and rice growing. There, the forest protection plays a big role. In Thailand, the use of land and forest protection are subjects mainly with the heightening of energy efficiency and fuel substitution. Malaysia, of course, promotes the economic development, has the leading GHG policy (traffic management in urban area, etc.), and wants the international technology transfer. (NEDO)

  14. Simplified clinical prediction scores to target viral load testing in adults with suspected first line treatment failure in Phnom Penh, Cambodia.

    Full Text Available BACKGROUND: For settings with limited laboratory capacity, 2013 World Health Organization (WHO guidelines recommend targeted HIV-1 viral load (VL testing to identify virological failure. We previously developed and validated a clinical prediction score (CPS for targeted VL testing, relying on clinical, adherence and laboratory data. While outperforming the WHO failure criteria, it required substantial calculation and review of all previous laboratory tests. In response, we developed four simplified, less error-prone and broadly applicable CPS versions that can be done 'on the spot'. METHODOLOGY/PRINCIPAL: Findings From May 2010 to June 2011, we validated the original CPS in a non-governmental hospital in Phnom Penh, Cambodia applying the CPS to adults on first-line treatment >1 year. Virological failure was defined as a single VL >1000 copies/ml. The four CPSs included CPS1 with 'current CD4 count' instead of %-decline-from-peak CD4; CPS2 with hemoglobin measurements removed; CPS3 having 'decrease in CD4 count below baseline value' removed; CPS4 was purely clinical. Score development relied on the Spiegelhalter/Knill-Jones method. Variables independently associated with virological failure with a likelihood ratio ≥ 1.5 or ≤ 0.67 were retained. CPS performance was evaluated based on the area-under-the-ROC-curve (AUROC and 95% confidence intervals (CI. The CPSs were validated in an independent dataset. A total of 1490 individuals (56.6% female, median age: 38 years (interquartile range (IQR 33-44; median baseline CD4 count: 94 cells/µL (IQR 28-205, median time on antiretroviral therapy 3.6 years (IQR 2.1-5.1, were included. Forty-five 45 (3.0% individuals had virological failure. CPS1 yielded an AUROC of 0.69 (95% CI: 0.62-0.75 in validation, CPS2 an AUROC of 0.68 (95% CI: 0.62-0.74, and CPS3, an AUROC of 0.67 (95% CI: 0.61-0.73. The purely clinical CPS4 performed poorly (AUROC-0.59; 95% CI: 0.53-0.65. CONCLUSIONS: Simplified CPSs retained

    Full Text Available Abstract Background The purpose of the research was to assess access to sexual and reproductive health services for migrant women who work as beer promoters. This mixed methods research was conducted in Phnom Penh, Cambodia, Bangkok, Thailand, Vientiane, Laos, and Hanoi, Vietnam during 2010 to 2011. Methods Focus groups were held with beer promoters and separate focus groups or interviews with key informants to explore the factors affecting beer promoters’ access to health care institutions for reproductive health care. The findings of the focus groups were used to develop a survey for beer promoters. This survey was conducted in popular health institutions for these women in each of the four Asian cities. Results Several common themes were evident. Work demands prevented beer promoters from accessing health care. Institutional factors affecting care included cost, location, environmental factors (e.g. waiting times, cleanliness and confidentiality and service factors (e.g. staff attitudes, clinic hours, and availability of medications. Personal factors affecting access were shyness and fear, lack of knowledge, and support from family and friends. The survey of the beer promoters confirmed that cost, location and both environmental and service factors impact on access to health care services for beer promoters. Many beer promoters are sexually active, and a significant proportion of those surveyed rely on sex work to supplement their income. Many also drink with their clients. Despite a few differences amongst the surveyed population, the findings were remarkably similar across the four research sites. Conclusions Recommendations from the research include the provision of evening and weekend clinic hours to facilitate access, free or low cost clinics, and health insurance through employer or government plans which are easy to access for migrants. Other improvements that would facilitate the access of beer promoters to these services include

    The entire country of Cambodia depends on agriculture for its economy. Rice is the staple food, making it the major agricultural product (roughly 80% of total national production). The target area of this study is western Cambodia, where rice production is the greatest in the country and most land is rainfed. Since most farmers rely only on their (non-science-based) experience, they would not adjust to changing rainfall and degraded water resources under climate change, so food security in the region would be seriously threatened (Monichoth et al., 2013). Under this condition, irrigation master plans are being considered by several ODA projects. This study aims to contribute to the design of such irrigation plans through the development of a real-time hydrological cycle - rice growth coupled simulation system. The purpose of the development of this system is to support decision making 1) for determining the necessary agricultural water resources and 2) for allocating limited water resources to various sectors. Rice growing condition as affected by water stress due to the water shortage is supposed to be shown for both of the cases with and without irrigation for several rainfall patterns. A dynamically coupled model of a distributed hydrological model (WEB-DHM., Wang et al., 2009) and a rice growth model (SIMRIW-rainfed, Homma et al., 2009) has been developed with a simple irrigation model. The target basin, a small basin in western Cambodia, is basically an ungauged basin and the model was validated by soil moisture, LAI, dry matter production of the rice crop, and rice yield, using both intensive field observation and satellite observations. Calibrating hourly satellite precipitation dataset (GSMaP/NRT) using ground rain gauges, hydrological cycle (soil moisture at three layers, river discharge, irrigatable water amount, water level of each paddy field, water demand of each paddy field, etc.) and rice growth (LAI, developmental index of the rice crop, dry matter

    Full Text Available Melioidosis infection, caused by Burkholderia pseudomallei, is increasingly reported in Cambodia. We hypothesized that implementation of an enhanced sputum testing protocol in a provincial hospital diagnostic microbiology laboratory would increase detection of B. pseudomallei. We tested 241 sputum specimens that were deemed acceptable for culture, comparing culture in selective enrichment broth followed by sub-culture on Ashdown’s medium to standard culture methods. Two specimens (0.8% were positive for B. pseudomallei using the enhanced protocol whereas one specimen (0.4% was positive using standard methods. These findings demonstrate that B. pseudomallei is rarely detected in sputum at this hospital. The low frequency of B. pseudomallei in sputum specimens precludes drawing any conclusions about the relative benefits of an enhanced sputum testing protocol at this site. Promoting clinician awareness of the infection and encouraging utilization of diagnostic microbiology services are likely to be important factors in facilitating identification of melioidosis.

    Plantation rubber (Hevea brasiliensis Müll. Arg.) is a viable economic resource for Southeast Asian countries. Consequently, rubber plantations are rapidly expanding into both climatically optimal and sub-optimal environments throughout mainland Southeast Asia, potentially changing the partitioning of water, energy, and carbon at multiple scales, compared with the traditional land covers they are replacing. Delineating the characteristics of biosphere-atmosphere exchange in rubber plantations is therefore important to understanding the impacts of such land use change on environmental processes. We have conducted eddy flux measurements in two rubber plantation sites: (1) Som Sanuk (SS), located northern Thailand; and (2) Cambodian Rubber Research Institute (CRRI), central Cambodia. Both sites have a distinct dry season. Measurements were made over a 3-year period. We used combination of actual evapotranspiration (ET) flux measurements and an inversed version of a simple 2-layer ET model for estimating the mean canopy stomatal conductances (gs), which is among the most effective measures for describing water and energy exchanges and tree water use characteristics. A main novelty in this analysis is that the rubber canopy conductance can be extracted from total surface conductance (including the canopy and the vegetation floor effects) and hence environmental and biological controls on rubber tree gs are explicitly compared at each site in different seasons and years. It is demonstrated how each studied rubber plantation copes with each strong seasonal drought via tree water use strategies. Potential tree water use deficit (precipitation (P) – potential evaporation (ET_POT)) for each season (i.e., December-February: DJF, March-May: MAM, June-August: JJA, and September-November: SON) revealed in which season and how the water use should be controlled. We found that in seasons when actual tree water use deficit (P

    Full Text Available Abstract Background Drug resistance of falciparum malaria is a global problem. Sulphadoxine/pyrimethamine-resistant and mefloquine-resistant strains of falciparum malaria have spread in Southeast Asia at lightning speed in 1980s-1990s, and the Cambodia-Thailand border is one of the malaria epidemic areas with the most severe forms of multi-drug resistant falciparum malaria. Methods Artemisinin-piperaquine (AP, dihydroartemisinin-piperaquine phosphate (DHP and artemether-lumefantrine (AL were used to treat 110, 55 and 55 uncomplicated malaria patients, respectively. The total dosage for adults is 1,750 mg (four tablets, twice over 24 hours of AP, 2,880 mg (eight tablets, four times over two days of DHP, and 3,360 mg (24 tablets, six times over three days of AL. The 28-day cure rate, parasite clearance time, fever clearance time, and drug tolerance of patients to the three drugs were compared. All of the above methods were consistent with the current national guidelines. Results The mean parasite clearance time was similar in all three groups (66.7 ± 21.9 hrs, 65.6 ± 27.3 hrs, 65.3 ± 22.5 hrs in AP, DHP and AL groups, respectively, and there was no remarkable difference between them; the fever clearance time was also similar (31.6 ± 17.7 hrs, 34.6 ± 21.8 hrs and 36.9 ± 15.4 hrs, respectively. After following up for 28-days, the cure rate was 95.1%(97/102, 98.2%(54/55 and 82.4%(42/51; and the recrudescence cases was 4.9%(5/102, 1.8%(1/55 and 17.6%(9/51, respectively. Therefore, the statistical data showed that 28-day cure rate in AP and DHP groups was superior to AL group obviously. The patients had good tolerance to all the three drugs, and some side effects (anoxia, nausea, vomiting, headache and dizziness could be found in every group and they were self-limited; patients in control groups also had good tolerance to DHP and AL, there was no remarkable difference in the three groups. Conclusions AP, DHP and AL all remained efficacious

    The HIV integrase enzyme is essential for the HIV life cycle as it mediates integration of HIV-1 proviral DNA into the infected cell's genome. Recently, the development of drugs capable of inhibiting integrase has provided major new options for HIV-infected, treatment-experienced patients with multidrug resistant virus, as well treatment-naïve patients. More than 40 amino acid substitutions within integrase have been described as associated mostly with resistance of HIV B-subtypes to currently available integrase inhibitors (INIs). We have analyzed the natural polymorphisms of the integrase coding region in 87 antiretroviral-naïve subjects (32 from Cambodia, 37 from Thailand and 18 from Vietnam) infected with CRF01_AE virus, the predominant HIV-1 strain circulating in Southeast Asia. The 864bp integrase coding region was sequenced using the ANRS consensus sequencing technique from plasma samples, and amino acid results were interpreted for drug resistance according to the ANRS (Updated July 2009, version 18) and Stanford algorithms (Version November 6, 2009). Alignment of the 87 amino acid sequences against the 2004 Los Alamos HIV-1 clade B consensus sequence showed that overall, 119 of 288 (41.3%) amino acid positions presented at least one polymorphism each. Substitutions found in >60% of study subjects occurred at: K14, A21, V31, S39, I72, T112, T124, T125, G134, I135, K136, D167, V201, L234 and S283. Also, new amino acid substitutions of as yet unknown significance were identified: E152K/H, S153F/L, N155I and E157G. None of the known integrase resistance mutations were observed, except E157Q found in one Cambodian subject (1.1%, CI 95% 0.02-6.3%). The clinical impact of this substitution on resistance of B and nonB-viruses to the licensed INI raltegravir is unclear. If this substitution is confirmed to compromise the virologic response to raltegravir, further studies will be needed to better assess the prevalence of this substitution among CRF01_AE virus.

    柬埔寨王国额勒赛水电站碾压混凝土重力坝防渗层变态混凝土施工厚度达3 m,现场人工加浆不仅工程量大、效率低,而且很难保证其均匀性。根据现场实际并结合国内变态混凝土施工经验,对碾压混凝土大坝上、下游防渗层变态混凝土采用在拌和楼集中拌制,自卸汽车运输,小型挖机配合入仓,再用高频振动棒振捣密实的方式施工,克服了变态混凝土人工加浆不均匀的缺陷。浇筑后的混凝土表面光洁,成型较好,无明显蜂窝麻面,内部密实,层间结合好。%The thickness of distorted concrete of impervious layer of a RCC gravity dam, Lower Stung Russei Chrum Hydro-power Station in Cambodia, is 3 m, which results in large labour intensity and low efficiency of grouting by workers, and the homogeneity can not be ensured. According to the practical situation, in combination of the experiences of distorted concrete con-struction in China, the distorted concrete of upstream and downstream imperious layer was mixed at a mixing plant, transported by dump truck, placed by small excavator and compacted and vibrated by high-frequency vibrating rod, which overcame the de-fect of inhomogeneous grouting. The surface of the concrete after grouting is clean and bright, the shaping is fine, no voids and pits exists, the interior is compacted and the inter-layers are well cohered.

  13. Exploring Strategies that Build Livelihood Resilience: a Case from Cambodia

    Directory of Open Access Journals (Sweden)

    Fikret Berkes

    2006-06-01

    Full Text Available Livelihoods in Cambodian fishing communities are complex and dynamic. Fluctuations in resource abundance, seasonal cycles of resource use, and changes in access create conditions that bring challenges for rural households, as do economic and policy drivers. Nonetheless, people are continuously “doing something” in response to these stresses and shocks. This paper sets out to explore how households and community members attempt to mitigate against such challenges. The analysis of livelihood stresses and shocks in two Cambodian fishing villages shows that diversification is a commonly used strategy for coping and adapting. Analyzing responses at multiple scales, with emphasis on resilience-building strategies at household and community levels, illuminates aspects of livelihoods. To study local-level perspectives of resilience, well-being was used as the surrogate of resilience, producing three clusters of responses related to economic conditions, resources, and relationships.

    Campylobacter are zoonotic bacteria and a leading cause of human gastroenteritis worldwide with Campylobacter jejuni and C. coli being the most commonly detected species. The aim of this study was to detect Campylobacter in humans and livestock (chickens, ducks, pigs, cattle, water buffalo, quail, pigeons and geese) in rural households by routine culturing and multiplex PCR in faecal samples frozen before analysis. Of 681 human samples, 82 (12%) tested positive by PCR (C. jejuni in 66 samples and C. coli in 16), but none by routine culture. Children were more commonly Campylobacter positive (19%) than adult males (8%) and females (7%). Of 853 livestock samples, 106 (12%) tested positive by routine culture and 352 (41%) by PCR. Campylobacter jejuni was more frequent in chickens and ducks and C. coli in pigs. In conclusion, Campylobacter proved to be highly prevalent by PCR in children (19%), ducks (24%), chickens (56%) and pigs (72%). Routine culturing was insufficiently sensitive in detecting Campylobacter in field samples frozen before analysis. These findings suggest that PCR should be the preferred diagnostic method for detection of Campylobacter in humans and livestock where timely culture is not feasible.

  18. Assessment of the Conditions for Linking Microfinance to Household Biodigester Construction in Cambodia

    Energy Technology Data Exchange (ETDEWEB)

    Chandararot, K.; Dannet, L.

    2006-10-15

    This report presents a comprehensive assessment of the conditions for helping households finance the construction of a biodigester. A micro-credit programme for biodigester users was jointly designed by the National Biodigester Programme (NBP), Netherlands Development Finance Company (FMO) and Microfinance Institutions (MFIs). By using in-depth interviews, a household survey and a desk study, it was determined that the demand for biodigester market was significant, with 96.5% of the studied households possessing the capacity to operate a biodigester. The research for demand for micro-credit showed that households were indeed in need of a financial aid (84%) but the majority was unwilling to borrow credit due to fear of inability to repay it. The ones willing to borrow demanded a credit size of 400,000-1,200,000 riels. The MFIs contacted (ACLEDA, Amret, CEB, Prasac, HURREDO) were interested in lending a micro-credit to biodigester users but were also concerned for the credit as it was for consumption and not production. It appeared that credit conditions desired by potential biodigester users were overall in line with MFIs offered conditions, but an interest rate gap was also in place. Some of the extensive suggestions on how to alleviate the problem offered in the report place FMO in the centre of operations as a possible guarantor of default loans, among other duties. The challenges likely to arise because of a roll-out strategy (linking potential biodigester users with micro-credit), as well plausible solutions are presented as well.

    Full Text Available This study tries to point out just a few of the most important characteristics of the toughest totalitarian regime of the contemporary period, that of the Cambodia’s Khmer Rouges. I underlined the main particularities that make it quite different from other Communist regimes of the XX-th century. I attempted also to establish a few connections and similarities with the belletristic literature, mainly with George Orwell’s work. In my approach, I started from the premise that the British writer was known as one of the most famous authors of anti-utopian novels. With the aid of the belletristic writing, I tried also to use an interdisciplinary approach.

    The Angkor complex is the one of the greatest cultural heritages in the world. It is constructed in the early 12th century, designated as a world cultural heritage by UNESCO in 1992. The temples at the Angkor complex are mainly made of sandstone and laterite. However, due to the tropical climate, plants, lichens and various microorganisms are growing well on the rock surface. Black crusts are also easily found on the stone surface. The 21st technical session of the International Coordinating Committee for the Safeguarding and Development of the Historic Site of Angkor (ICC-Angkor) held in 2012 recommended that to preserve both the biofilms and the forest cover and to prohibit the biocides (chlorine-based) and organic biocides. However, there are many reports that lichens and microorganisms accelerate rock weathering. It is important to clarify that how the biofilm on the Angkor temples affect Angkor sandstones. We sampled Angkor sandstone covered by black crust at the Bayon temple, Angkor complex, and observed the section and the surface of the rock sample by using SEM. Surfaces of the samples are not polished in order to observe the original condition. The samples are coated with gold for 180 seconds. The depth of the black crust is up to 1 mm. Many filamentous materials were found on the black crust. Average energy-dispersive X-ray spectroscopy data of the five areas of ca. 20 μm ×15 μm in the black crusts shows that over 80 % of the filamentous materials are compounds of carbon. It seems that these materials are hyphae. The shape of the hypha is like a thread and its size is few μm in diameter and up to several centimeters in length. Black crusts are consisted of elements and compounds of carbon, Na, Mg, Al, Si, Cl, K, Ca, and Fe. Further research has to be done to find out the better and proper way of conservation for the Angkor complex.

    2013-01-15

    Reduced Emissions from Deforestation and Forest Degradation in developing countries (REDD +) has moved to the central stage of the climate change debate by being promoted as a significant, cheap, and quick win-win strategy to reduce greenhouse gas emissions and thereby mitigate climate change. In order to be successful in reducing emissions while providing the projected social and environmental co-benefits, REDD + needs to overcome key challenges of insecure forest tenure and inequity in the distribution of benefits. Such challenges threaten to affect the livelihoods and well-being in the local communities and in turn the effectiveness of REDD+. While REDD + programs will affect the participating communities, there is limited knowledge as to what social impacts these projects may bring to the local population. Similarly, assessment of these social dimensions has received little attention until recently, and is consequently out of sync with the realities of REDD + projects. The present paper aims to shed light on the methodological and contextual challenges in the assessment of the social dimensions of REDD+. Some of the main social concerns of REDD + are outlined with an emphasis on the uniqueness and complexity of REDD + interventions. Recently proposed approaches to assess social impacts in REDD + are critically assessed in terms of the diversity of frameworks proposed, choice of social indicators, and data collection requirements. Specifically, these methodological implications are further discussed in the light of the social dimensions and the prescribed regulations of REDD + in a Cambodian context. - Highlights: Black-Right-Pointing-Pointer Insecure tenure and inequitable benefit sharing are main social concerns in REDD +. Black-Right-Pointing-Pointer Two guides to social assessments in REDD + are critically reviewed. Black-Right-Pointing-Pointer Mismatch between social assessment requirements and the reality of REDD + is analyzed. Black-Right-Pointing-Pointer Concrete, topical examples from Cambodian REDD + are used. Black-Right-Pointing-Pointer Support the claim to add qualitative assessment of social dimensions in REDD +.

L'Xpert a été réalisé plus souvent lorsqu'il était disponible en POC. Une plus faible proportion de PVVIH a eu un diagnostic de TB dans les sites POC que dans les sites non-POC ; cependant, dans les sites POC, une proportion plus élevée des patients ayant eu un diagnostic de TB a eu une bactériologie positive. L'accord entre l'Xpert et les autres tests (par exemple la microscopie de frottis ou la culture) a été médiocre. Dans l'ensemble, l'évaluation des patients présumées de TB-MDR a augmenté après le lancement de l'Xpert, mais parmi les patients ayant eu une pharmacorésistance confirmée par test de pharmacosensibilité, seulement 46% ont eu une résistance à la rifampicine qui aurait été identifiée par Xpert.Conclusion : Même si l'utilisation de l'Xpert a été faible, l'Xpert pourrait avoir contribué à une augmentation de l'évaluation des suspicions de TB-MDR et à un déclin du traitement empirique des PVVIH quand il est disponible sur place.

    2012-06-01

    Full Text Available Despite the rise of Cambodia’s GDP and other development indicators, continuing extreme poverty combined with very rapid conversion of traditional subsistence lands, forests, and waters into economic land concessions (ELCs to national and transnational companies is leading to intensified land insecurity issues and other human rights problems that may destabilize the country.  An elite sector of Cambodian society comprised of the heads of state, business, and the military is implicated as the central cause of ongoing poverty and land loss.   This paper outlines the problematic nature of the ELC processes that began in the post-conflict era and continue today, and adapts Roy Rappaport’s concepts of cognized/operational environments within a political and historical framework for analyzing the strategies of these elites, and compares their cognized environments with those of indigenous Kuoy peoples who are among those whose lands are threatened by ELCs, and suggests that the high-modern discourses of development adhered to by the elites is based on ultimate sacred postulates just as much as are the explicitly religious discourses of traditional Kuoy peoples.

  2. Dams on Mekong tributaries as significant contributors of hydrological alterations to the Tonle Sap Floodplain in Cambodia

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available River tributaries have a key role in the biophysical functioning of the Mekong Basin. Of particular attention are the Sesan, Srepok, and Sekong (3S rivers, which contribute nearly a quarter of the total Mekong discharge. Forty two dams are proposed in the 3S, and once completed they will exceed the active storage of China's large dam cascade in the upper Mekong. Given their proximity to the lower Mekong floodplains, the 3S dams could alter the flood-pulse hydrology driving the productivity of downstream ecosystems. Therefore, the main objective of this study was to quantify how hydropower development in the 3S would alter the hydrology of the Tonle Sap floodplain, the largest wetland in the Mekong and home to one of the most productive inland fisheries in the world. We coupled results from four numerical models representing the basin's surface hydrology, water resources development, and floodplain hydrodynamics. The scale of alterations caused by hydropower in the 3S was compared with the basin's definite future development scenario (DF driven by the upper Mekong dam cascade. The DF or the 3S development scenarios could independently increase Tonle Sap's 30 day minimum water levels by 30 ± 5 cm and decrease annual water level fall rates by 0.30 ± 0.05 cm d−1. When analyzed together (DF + 3S, these scenarios are likely to eliminate all baseline conditions (1986–2000 of extreme low water levels, a~particularly important component of Tonle Sap's environmental flows. Given the ongoing trends and large economic incentives in the hydropower business in the region, there is a high possibility that most of the 3S hydropower potential will actually be exploited and that dams would be built even in locations where there is a high risk of ecological disruptions. Hence, retrofitting current designs and operations to promote sustainable hydropower practices that optimize multiple river services – rather than just maximize hydropower generation – appear to be the most feasible alternative to mitigate hydropower-related disruptions in the Mekong.

    This study aimed to identify factors influencing poisoning symptoms among 153 mixed insecticide-exposed vegetable farmers in one Cambodian village, where 153 factory workers were selected as a comparative nonexposed group. The research instruments were questionnaires and reactive-paper test kits. The majority of vegetable farmers were male, with approximately 87% of the total participants with an average age of 34 years. The personal hygiene scores of most vegetable farmers (108; 70.8%) were moderate, and knowledge scores were at poor level (131; 85.6%). Abnormally low cholinesterase (ChE) levels were detected among 119 (77.8%) farmers. Multiple logistic regression analysis was used to identify factors associated with possible poisoning symptoms. This study found that mixing an average of four to six types of insecticides (odds ratio [OR] = 4.6; P = .03) and abnormal ChE level (OR = 4.09; P = .004) was associated with central nervous system (CNS) symptoms. Age group >45 years (OR = 2.8; P = .04) and type of vegetable "other" (OR = 2.73; P = .02) were associated with gastrointestinal symptoms. Type of insecticide, organophosphates (OPs) and carbamates (CMs) (OR = 3.2; P = .04), was associated with respiratory symptoms. It is recommended that farmers should reduce insecticide spraying times, increase their use of personal protective equipment (PPE), and undergo training on insecticide use. These combined measures should improve the insecticide-related health status of vegetable farmers in this area.

    Objectif : Décrire la mise en œuvre et l'utilisation du test Xpert(R) MTB/RIF afin de diagnostiquer la tuberculose (TB) parmi des personnes vivant avec le VIH/SIDA (virus de l'mmunodéficience humaine/syndrome de l'immunodéficience acquise ; PLHA) au Cambodge.Schéma : Après le déploiement du test Xpert, une évaluation a été réalisée dans quatre provinces du Cambodge entre mars et décembre 2012 afin de déterminer l'utilisation, la performance et le délai d'exécution du Xpert parmi les PLHA. Des données ont été recueillies à partir des dossiers papiers des patients.Résultats : Sur 497 PLHA ayant une grille de symptômes de TB positive, 357 (72%) ont bénéficié d'une microscopie de frottis et 250 (50%) ont eu un test Xpert ; 25 (10%) PLHA testés par Xpert étaient positifs pour la TB et aucun n'était résistant à la rifampicine. L'utilisation du Xpert est passée de 23% à 75% avec un délai d'exécution médian d'un jour. Dans les districts, l'utilisation allait de zéro à 85% et le délai de mise en œuvre allait de zéro à 22 jours.Conclusion : Si les données précoces montrent une utilisation croissante du Xpert chez les PLHA avec une grille de symptômes positive, la majorité des patients bénéficiait initialement d'un diagnostic par examen microscopique de frottis. Les délais de formation et les problèmes posés par l'envoi des spécimens peuvent avoir contribué à la variabilité du recours au Xpert et au délai de sa mise en œuvre, particulièrement dans les endroits dépourvus de possibilité de test Xpert sur place. Davantage de soutien aux programmes, notamment en termes d'envoi des spécimens et de retour des résultats, pourrait faciliter son utilisation appropriée.

    The prevalence, availability, and use of antimalarial medicines (AMLs) were studied in six Cambodian provinces along the Thai-Cambodian border. The study was divided into two parts: the first looked at the quality of AMLs available in Pursat, Pailin, Battambang, Bantey Meanchey, Oddar Meanchey, and Preah Vihear and the second obtained information about the availability and use of AMLs. A randomized sampling methodology was used to select locations and collect samples, which were screened using Global Pharma Health Fund (GPHF) Minilabs. A subset of samples was sent to quality control laboratories for confirmatory testing. For the second part of the study, face-to-face interviews were conducted using standardized surveys with members of randomly selected households and staff of health facilities in the villages with highest malaria incidence to find out where they acquired their AMLs and which were most frequently used. The results showed an overall failure rate of 12.3% (n = 46 of 374 total AML samples). The causes of medication sample failure were low active pharmaceutical ingredient (API) content, failed dissolution properties, and unacceptably high levels of impurities. A total of 86.2% of survey respondents (n = 1,648 of 1,912) reported a member of their household having malaria in the previous year. The most commonly used medicines were paracetamol (67.1% of respondents), Malarine (A+M co-blistered, 28.6%), artesunate + mefloquine co-blistered (public sector product, 17.3%), quinine (16.7%), and artesunate monotherapy (11.9%). Health staff typically prescribed co-blistered artesunate plus mefloquine in the public sector (67.8%), the artesunate plus mefloquine "social marketing" product from Population Services International (PSI), Malarine (50.3%) in the private sector, artemether (49.7%), chloroquine (39%) and paracetamol (72.9%) to reduce fever.

    From July 2000 to July 2001, the hazard analysis and critical control points (HACCP) system was implemented to the benefit of the traditional sandwich production in Phnom Penh City Sandwiches were initially analyzed for bacterial indicators among 6 large-scale producers during a 2 months period. In the second stage of the study, two selected producers were involved in the HACCP process. Microbiological analyses revealed a poor sanitary quality of samples from all the production lines tested. Implementation of HACCP method resulted in a reduction of microbial contamination, but this decrease was not significant compared with others steps of HACCP process (chi2 test for trend, p > 0.05). HACCP system was well accepted by producers but routine practices and wrong perception by production-line workers did limit the success of the process. A regulation on the mass catering sector should be part of a large strategy of food safety and environmental health in the city.

    Full Text Available This study develops a modelling framework for utilizing very high-resolution (VHR aerial imagery for monitoring stocks of above-ground biomass (AGB in a tropical forest in Southeast Asia. Three different texture-based methods (grey level co-occurrence metric (GLCM, Gabor wavelets and Fourier-based textural ordination (FOTO were used in conjunction with two different machine learning (ML-based regression techniques (support vector regression (SVR and random forest (RF regression. These methods were implemented on both 50-cm resolution Digital Globe data extracted from Google Earth™ (GE and 8-cm commercially obtained VHR imagery. This study further examines the role of forest biophysical parameters, such as ground-measured canopy cover and vertical canopy height, in explaining AGB distribution. Three models were developed using: (i horizontal canopy variables (i.e., canopy cover and texture variables plus vertical canopy height; (ii horizontal variables only; and (iii texture variables only. AGB was variable across the site, ranging from 51.02 Mg/ha to 356.34 Mg/ha. GE-based AGB estimates were comparable to those derived from commercial aerial imagery. The findings demonstrate that novel use of this array of texture-based techniques with GE imagery can help promote the wider use of freely available imagery for low-cost, fine-resolution monitoring of forests parameters at the landscape scale.

    2016-02-01

    Full Text Available Fortification of fish and soy sauces is a cost-effective strategy to deliver and increase iron intake in the Cambodian diet, as both are widely consumed by the entire population. In order to qualify as fortified sauces recognized by international regulations, iron content must be between 230 and 460 mg/L, whilst nitrogen and salt should contain no less than 10 g/L and 200 g/L respectively. This survey aims to analyze the progress of the fortification program. Through a better understanding of its obstacles and successes, the paper will then consider approaches to strengthen the program. Two hundred and fifty two samples were collected from 186 plants and 66 markets in various provinces. They were then analyzed for iron, nitrogen and salt content. The study demonstrates that 74% of fortified fish and soy sauces comply with Cambodian regulations on iron content. 87% and 53.6% of the collected samples do not have adequate level of nitrogen and salt content, respectively. The paper will discuss additional efforts that need to be implemented to ensure the sustainability of the project, including the need to: (i comply with International Codex; (ii adopt mandatory legislation; and (iii ensure enforcement.

  20. Seasonal variability in the composition of glycerol dialkyl glycerol tetraethers (GDGTs) associated with suspended sediment transported by the Mekong River, Cambodia

    The branched/isoprenoid tetraether (BIT) index has been proposed to be a proxy for the relative amounts of terrestrially verses marine-derived organic matter preserved in coastal sediments. To accurately interpret this index, it is first necessary to understand how this index and its constituents vary in non-marine environments, such as rivers and soils. As the composition of organic matter exported by tropical rivers can vary considerably between the dry and rainy seasons, we assessed the seasonal variability of the branched and isoprenoid GDGTs (glycerol dialkyl glycerol tetraethers) associated with suspended sediment exported by the Mekong River. Our results demonstrate that the concentration (in ng/L) of crenarchaeol (GDGT IV), and branched GDGTs (GDGTs I, II, and III) was positively correlated with discharge and suspended sediment. When normalized to organic carbon (OC) content, dry-season values were consistently lower than rainy-season values for crenarchaeol (1.0 ± 0.6 vs. 4.1 ± 2.1 ng GDGT/mg OC) and branched (3.8 ± 1.5 vs. 16.8 ± 10.6 ng GDGT/mg OC) GDGTs. Low dry-season values were likely due to the dilution of GDGTs by phytoplankton production. The BIT index of suspended sediments ranged from 0.56 to 0.93 throughout the year, with a mean of 0.77. No seasonal trends were observed in this variability, nor was it correlated with bulk suspended sediment concentration or composition. These values are considerably lower than the theoretical terrestrial end-member of 1 due to the presence of crenarchaeol. Between 47 to 59% of the crenarchaeol associated with riverine suspended sediments was derived from intact polar groups bound to core GDGTs, whereas 48 to 65% of the branched GDGTs were intact. To further understand additional sources of GDGTs within the Mekong River catchment, we analyzed soil and sediment samples from rainforests, pastures, wetlands, river beds, and river banks during the rainy season. Anaerobic environments, such as wetlands and river bed sediments, consistently had the highest abundance of both branched GDGTs (between 34.8 to 212.5 ng/mg OC) and crenarchaeol (between 51.5 to 132.3 ng/mg OC), suggesting that these environments are especially important sources of GDGTs to river particles, and potentially to sediments preserved in marine environments. In conclusion, the high variability of the BIT index in Mekong River sediments suggests that it should be used in conjunction with other proxies of terrestrially-derived material to accurately interpret the origin of sediments preserved in coastal settings in the tropics.

    The potential arsenite bioteansformation activity of arsenic was investigated by examining bacterial arsenic arsenite-oxidizing gene such as aoxS, aoxR, aoxA, aoxB, aoxC, and aoxD in high arsenic-contaminated drinking water produced from the surface water of floating houses. There is a biogeochemical cycle of activity involving arsenite oxidase aox system and the ars (arsenic resistance system) gene operon and aoxR leader gene activity in Alcaligenes faecalis SRR-11 and aoxS leader gene activity in Achromobacter xylosoxidans TSL-66. Batch experiments showed that SRR-11 and TSL-66 completely oxidized 1 mM of As (III) to As (V) within 35-40 h. The leaders of aoxS and aoxR are important for gene activity, and their effects in arsenic bioremediation and mobility in natural water has a significant ecological role because it allows arsenite oxidase in bacteria to control the biogeochemical cycle of arsenic-contaminated drinking water produced from surface water of floating houses.

    2007-06-01

    The antiparasitic effect of cassava (Manihot esculenta Crantz) was tested in goats artificially infected with gastrointestinal parasitic nematodes. Each experimental group consisted of 6 pen-fed goats kept on a slatted floor. The treatments compared were: 1) controls fed grass only, 2) cassava replaced grass for 3 weeks from the commencement of larval dosing period, and 3) cassava replaced grass for 3 weeks after the worm infection was patent. A total of 2000 mixed-species infective nematode larvae (L3) were administered to each goat in four doses of 500 L3/day, commencing 5 weeks after removal of previously acquired infections with ivermectin. The faecal egg counts (FEC) reduced in both cassava fed groups during the time of feeding, compared to the controls. Although, FEC increased differently with time (P diet, they do suggest that feeding, or supplementation, of cassava over an extended period may prove beneficial.

  6. Economic and Environmental Performances of Small-Scale Rural PV Solar Projects under the Clean Development Mechanism: The Case of Cambodia

    Directory of Open Access Journals (Sweden)

    Ellen De Schepper

    2015-09-01

    Full Text Available The two core objectives of the Clean Development Mechanism (CDM are cost-effective emission reduction and sustainable development. Despite the potential to contribute to both objectives, solar projects play a negligible role under the CDM. In this research, the greenhouse gas mitigation cost is used to evaluate the economic and environmental performances of small-scale rural photovoltaic solar projects. In particular, we compare the use of absolute and relative mitigation costs to evaluate the attractiveness of these projects under the CDM. We encourage the use of relative mitigation costs, implying consideration of baseline costs that render the projects profitable. Results of the mitigation cost analysis are dependent on the baseline chosen. To overcome this drawback, we complement the analysis with a multi-objective optimization approach, which allows quantifying the trade-off between economic and environmental performances of the optimal technologies without requiring a baseline.

    Full Text Available Abstract Background The area along the Thai-Cambodian border is considered an epicenter of anti-malarial drug resistance. Recently, parasite resistance to artemisinin-based therapies has been reported in the area. The artemisinin resistance containment project was initiated in November 2008, with the aim to limit resistant parasites and eliminate malaria in this region. This study describes the response to artemisinin-based therapy among falciparum malaria patients in the area, using data from the malaria surveillance programmed under the containment project. Methods The study was conducted in seven provinces of Thailand along the Thai-Cambodian border. Data of Plasmodium falciparum-positive patients during January 2009 to December 2011 were obtained from the electronic malaria information system (eMIS Web-based reporting system. All P. falciparum cases were followed for 42 days, as the routine case follow-up protocol. The demographic characteristics of the patients were described. Statistical analysis was performed to determine the cure rate of the current standard anti-malarial drug regimen--mefloquine-artesunate combination therapy (MAS. The proportion of patients who remained parasite-positive at each follow-up day was calculated. In addition, factors related to the delayed parasite clearance on day-3 post-treatment, were explored. Results A total of 1,709 P. falciparum-positive cases were reported during the study period. Almost 70% of falciparum cases received MAS therapy (n = 1,174. The majority of cases were males, aged between 31 and 50 years. The overall MAS cure rate was >90% over the three-year period. Almost all patients were able to clear the parasite within 7 to 14 days post-treatment. Approximately 14% of patients undergoing MAS remained parasite-positive on day-3. Delayed parasite clearance was not significantly associated with patient gender, age, or citizenship. However, delayed parasite clearance varied across the study area. Conclusion Anti-malarial drug-resistant parasites should be closely monitored in the area along the Thai-Cambodian border. Although the MAS cure rate in this study area was above 90%, an increasing trend of treatment failure has been reported in neighboring parts. Effective malaria surveillance is an important component to monitor drug-resistance in the malaria containment project.

    Abstract Background Recent investigations by the Ministry of Health of Cambodia suggest that counterfeit medicines have been introduced into the pharmaceutical market in tampered packaging. To further explore this possibility, an interview survey was conducted at the wholesaler level to investigate the medicinal supply chain in Cambodia.

    To test whether Zika virus has adapted for more efficient transmission by Aedes aegypti mosquitoes, leading to recent urban outbreaks, we fed mosquitoes from Brazil, the Dominican Republic, and the United States artificial blood meals containing 1 of 3 Zika virus strains (Senegal, Cambodia, Mexico) and monitored infection, dissemination, and virus in saliva. Contrary to our hypothesis, Cambodia and Mexica strains were less infectious than the Senegal strain. Only mosquitoes from the Dominican Republic transmitted the Cambodia and Mexica strains. However, blood meals from viremic mice were more infectious than artificial blood meals of comparable doses; the Cambodia strain was not transmitted by mosquitoes from Brazil after artificial blood meals, whereas 61% transmission occurred after a murine blood meal (saliva titers up to 4 log10 infectious units/collection). Although regional origins of vector populations and virus strain influence transmission efficiency, Ae. aegypti mosquitoes appear to be competent vectors of Zika virus in several regions of the Americas.

    Full Text Available I was sixteen years old when I first read about Norodom Sihanouk and Cambodia. Jacqueline Kennedy’s visit to Cambodia in November 1967 had been widely reported by the press in my homeland, Chile, where her assassinated husband was greatly admired. Through Jackie Kennedy’s visit to Cambodia, I became interested in Norodom Sihanouk’s fascinating life, totally unaware that, years later, our paths would cross and I would become his private secretary. My Cambodian friends often tell me that it was my destiny. In 1967, I wanted to know more about Cambodia. Since there was no information available, I wrote to the Cambodian mission at the United Nations. I found it unbelievable, but four months later I received a handwritten letter back from Sihanouk himself. That began our friendship, which was first conducted through correspondence...

  14. Cambodia’s Façade Democracy and European Assistance

    Directory of Open Access Journals (Sweden)

    Markus Karbaum

    2011-01-01

    Full Text Available Although Cambodia adopted a modern democratic constitution in 1993, Prime Minister Hun Sen has consolidated an autocratic regime in which elections are the only way political competition plays out, and even that competition is limited. Freedom of expression, horizontal and vertical control mechanisms, and civil participation have been reduced to almost zero by the Royal Government of Cambodia. Irrespective of the deinstitutionalization of liberal principles, the European Commission and some EU member states still perceive Cambodia as moving toward democratization. In the case of Cambodia, the difficulty of external democracy promotion is compounded by the limited impact of formal state institutions, which are completely undermined by kinship relations, personal networks, clientelism and nepotism. However, one can observe not only non-effective efforts toward European democracy promotion, but also increasing human rights violations due to trade facilitations, namely the EU’s “Everything But Arms” initiative.

    2013-12-01

    In Cambodia, most poultry are raised in backyard flocks with a low level of biosecurity, which increases the risk of spread of infectious diseases. The aim of this study was to evaluate the effectiveness of a practical biosecurity intervention based on affordable basic measures. A cluster randomised trial was conducted in 18 villages in Cambodia from November 2009 to February 2011. Generalised estimating equations were used to test the association between the intervention and mortality rates in flocks of chickens and ducks. Mortality rates in chicken flocks in intervention villages (mean 6.3%, range 3.5-13.8%, per month) were significantly higher than in control villages (mean 4.5%, range 2.0-9.7%, per month; Pbiosecurity intervention implemented in this study was not associated with improvements in poultry mortality rates. These findings suggest that basic biosecurity measures may not suffice to limit the spread of infectious diseases in backyard poultry flocks in Cambodia.

    This article describes a case we experienced while doing volunteer medical work in Cambodia for six months in 2002. By examining treatment of a 14-year-old female land mine victim with maxillofacial injuries, we report on the present socio-medical situation in Cambodia. This case suggests the lack of infrastructure, facilities, human resources, and patient education make it extremely difficult to provide patients with proper treatment, including general anesthesia. A comparison of land mine victim statistics between 2002 and 2005 reveals significant problems.

  7. Cambodia–China Relations: A Positive-Sum Game?

    Directory of Open Access Journals (Sweden)

    Pheakdey Heng

    2012-01-01

    Full Text Available China has re-emerged to become a dominant foreign player in Cambodia. Politically, Cambodia is one of China’s oldest and closest allies. Economically, China is Cambodia’s top foreign investor, a major donor, and an increasingly important trading partner. Culturally, Chinese values are deeply embedded in many aspects of Cambodian society. However, China’s dominance is surrounded by renewed controversies. While the government warmly welcomes Chinese aid, saying that it comes with no strings attached, many experts are concerned that China is providing aid for more nefarious reasons. Critics also accuse Chinese investment and aid of having exacerbated corruption, weakened governance and harmed human rights, and of ruining Cambodia’s natural resources and environment. With such controversies, it is relevant and significant to assess the roles that China has played and continues to play in Cambodia’s socio-economic development. Using expert interviews, media analysis and an extensive literature review, this paper uniquely contributes to the existing discussion on China–Cambodia relations by closely examining the controversies of China’s investment and aid, critically analysing China’s interests in Cambodia, and asking if the relationship between the two nations is a positive-sum game.

    In May 2005, SNV and the Ministry of Agriculture, Forestry and Fisheries (MAFF) agreed to a joint development of a National Biodigester Programme (NBP) in Cambodia as a way to create an indigenous, sustainable energy source in the country and to utilize the potential of biogas in the country. The overall objective of the first phase of the National Biodigester Programme is 'The dissemination of domestic biodigesters as an indigenous, sustainable energy source through the development of a commercial, market oriented, biodigester sector in selected provinces of Cambodia'. The program aims to support the construction of 17,500 biodigesters in at least 6 provinces over the period of 2006 to 2009. To gain insights and feedbacks on the impacts of their activities to date, NBP commissioned the Cambodia Institute of Development Study (CIDS) to carry out a Biodigester User Survey in January 2007. The purpose of the survey is to evaluate the effects of domestic biodigester installations, as supported by the program, on 100 households in 3 provinces in Cambodia- Kampong Cham, Kandal and Svay Rieng.

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Abstract Background The tuberculosis case register is the data source for the reports submitted by basic management units to the national tuberculosis program. Our objective was to measure the data entry time required to complete and double-enter one record, and to estimate the time for the correction of errors in the captured information from tuberculosis case registers in Cambodia and Viet Nam. This should assist in quantifying the additional requirements in human resources for national programs moving towards electronic recording and reporting. Methods Data from a representative sample of tuberculosis case registers from Cambodia and Viet Nam were double-entered and discordances resolved by rechecking the original case register. Computer-generated data entry time recorded the time elapsed between opening of a new record and saving it to disk. Results The dataset comprised 22,732 double-entered records of 11,366 patients (37.1% from Cambodia and 62.9% from Viet Nam. The mean data entry times per record were 97.5 (95% CI: 96.2-98.8 and 66.2 (95% CI: 59.5-73.0 seconds with medians of 90 and 31 s respectively in Cambodia and in Viet Nam. The percentage of records with an error was 6.0% and 39.0% respectively in Cambodia and Viet Nam. Data entry time was inversely associated with error frequency. We estimate that approximately 118-person-hours were required to produce 1,000 validated records. Conclusions This study quantifies differences between two countries for data entry time for the tuberculosis case register and frequencies of data entry errors and suggests that higher data entry speed is partially offset by requiring revisiting more records for corrections.

    Full Text Available Cambodia is sadly known for the terrible crimes committed during the Khmer Rouge regime between 1975 and 1979. The history that followed this period was marked by a multifaceted conflict that lasted for nearly 20 more years. In this particularly complex context, the process of disarmament, demobilization, and reintegration (DDR was essential to guarantee the transition of this devastated country towards peace and stability. The objective of this article is to present the initiatives of DDR in Cambodia between 1992 and 2002, the challenges and difficulties brought by their implementation, and the causes of their failure. The article also outlines the government's policy that led to the dismantlement of the Khmer Rouge in the 1990s, as well as the arms control programs implemented between 2000 and 2008. These two measures contributed successfully to pacify the country, to improve security conditions and to mitigate the failure of DDR.

    Arsenic-induced skin cancer is a significant global health burden. In areas with arsenic contamination of water sources, such as China, Pakistan, Myanmar, Cambodia and especially Bangladesh and West Bengal, large populations are at risk of arsenic-induced skin cancer. Arsenic acts as a co-carcinogen with ultraviolet (UV) radiation and affects DNA damage and repair. Nicotinamide (vitamin B3) reduces premalignant keratoses in sun-damaged skin, likely by prevention of UV-induced cellular energy ...

    The Ministry of Agriculture, Forestry and Fisheries of the Kingdom of Cambodia (MAFF) and The Netherlands Development Organisation (SNV-Cambodia) have agreed on cooperating in the set-up and implementation of a National Biogas Programme. The programme officially started after the launching ceremony in March 2006. The objective the National Biodigester Programme (NBP) is 'The dissemination of domestic biodigesters as an indigenous, sustainable energy source through the development of a commercial, market oriented, biodigester sector in selected provinces of Cambodia'. To evaluate the effectiveness of the NBP a Biodigester User Survey has been undertaken with two specific objectives, being: (1) To evaluate the effect of domestic biodigester installations, as perceived by the user, by conducting a representative quantitative random survey of 120 households constructed till 31/08/2010 under the NBP in 8 provinces in Cambodia as well as how the users have experienced the programme activities such as promotion, construction, quality assurance, training and after-sales service; and (2) To evaluate the impact of the program on sustainable development and on a number of GHG emission causing activities, such as fossil and fuel wood consumption and manure management practices. The results of which are presented in this report. Since the beginning of 2006 the National Biodigester Programme (NBP) has supported the construction of over 8,000 biodigesters by July 2010. This Biodigester User Survey (BUS) aimed to evaluate the effect of domestic biodigester installations by conducting research with selected representatives to obtain a sample with a confidence level of 95%. The sample size was 120 with a two-step random selection, the selection was made from households in the NBP database. First, 12 out of 82 districts with were randomly selected, and secondly 120 households were randomly selected from these 12 districts, which cover 7 of the 8 provinces in which NBP
