    Background 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. Methods 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. Principal Findings 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. Conclusions/Significance 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.

    A survey of the genetic ancestry of 125 Cambodian children resident in Siem Reap province was undertaken, based on eight Y-chromosome binary polymorphisms and sequencing of the mtDNA HV1 region. The data indicated a largely East Asian paternal ancestry and a local Southeast Asian maternal ancestry. The presence of Y-chromosomes P* and R1al* was suggestive of a small but significant Indo-European male ancestral component, which probably reflects the history of Indian, and later European, influences on Cambodia.

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

    Background There are limited data on the epidemiology of paediatric healthcare-associated infection (HCAI) and infection control in low-income countries. We describe the value of intermittent point-prevalence surveys for monitoring HCAI and evaluating infection control interventions in a Cambodian paediatric hospital. Methods Hospital-wide, point-prevalence surveys were performed monthly in 2011. Infection control interventions introduced during this period included a hand hygiene programme and a ventilator-associated pneumonia (VAP) care bundle. Results Overall HCAI prevalence was 13.8/100 patients at-risk, with a significant decline over time. The highest HCAI rates (50%) were observed in critical care; the majority of HCAIs were respiratory (61%). Klebsiella pneumoniae was most commonly isolated and antimicrobial resistance was widespread. Hand hygiene compliance doubled to 51.6%, and total VAP cases/1000 patient-ventilator days fell from 30 to 10. Conclusion Rates of HCAI were substantial in our institution, and antimicrobial resistance a major concern. Point-prevalence surveys are effective for HCAI surveillance, and in monitoring trends in response to infection control interventions. PMID:23418156

    Hepatitis E virus (HEV) is a growing public health problem in many countries. In this study, we investigated HEV seroprevalence among the general population in the Siem Reap province, Cambodia, and performed HEV genetic analysis with the aim to develop an HEV prevention strategy. This seroepidemiological cross-sectional study conducted from 2010 to 2014 included 868 participants from four different locations in Siem Reap province, Cambodia. They answered questionnaires and provided blood samples for the analysis of hepatitis virus infections. Among the participants (360 men and 508 women; age range, 7-90 years), the prevalence of anti-HEV IgG was 18.4% (95% confidence interval: 15.9-21.0); HEV RNA was detected in two participants (0.23%) and was classified as genotype 3 and 4. Full-length genome of the genotype 4 isolate, CVS-Sie10, was sequenced; it contained 7,222 nucleotides and three ORFs and demonstrated high sequence identity with the swine China isolates swGX40 (95.57%), SS19 (94.37%), and swDQ (91.94%). Multivariate logistic regression analysis revealed that men, elderly people, and house workers were risk groups significantly associated with the positivity for anti-HEV IgG. This is the first report on the detection of HEV genotype 4 in humans in Cambodia and on the complete genome sequence of HEV genotype 4 from this country. Our study demonstrates that new HEV infection cases occur frequently among the general population in Cambodia, and effective preventive measures are required. PMID:26317620

    The population of Cambodia stood at 6.25 million in 1986, with an average annual growth rate of 2.1%. Life expectancy is presently 42 years for men and 44.9 years for women. The government is currently disputed between resistance groups and Vietnamese-installed authorities in Phnom Penh. No single authority controls the entire country. The urban population increased sharply during the 1970-75 war, but after seizing power the Khmer Rouge forced most urban residents to return to rural areas as peasants. Massive numbers of people were executed for political reasons or died of starvation and disease during the Khmer Rouge period and after the dislocations caused by the Vietnamese invasion: an estimated 1.5-3 million people are estimated to have died out of a 1975 population of 7.3 million. The resistance forces have grown in size and effectiveness since 1985 and now challenge Vietnam's position in Cambodia. The Cambodian economy, badly damaged by the war and the Khmer Rouge regime, has only slowly begun to recover. Per capita gross national product (GNP) is estimated at less than US$100. The food situation remains precarious, with shortages of rice, meat, vegetables, sugar, flour, and dairy products. Extensive damage to the country's irrigation system, on which rice production depends, has only begun to be repaired. Basic services such as electricity and water are erratic. Although literacy and primary education campaigns have achieved success, health conditions remain poor. PMID:12177940

    This is an image of the area around the city of Angkor, Cambodia. The city houses an ancient complex of more than 60 temples dating back to the 9th century. The principal complex, Angkor Wat, is the bright square just left of the center of the image. It is surrounded by a reservoir that appears in this image as a thick black line. The larger bright square above Angkor Wat is another temple complex called Angkor Thom. Archeologists studying this image believe the blue-purple area slightly north of Angkor Thom may be previously undiscovered structures. In the lower right is a bright rectangle surrounded by a dark reservoir, which houses the temple complex Chau Srei Vibol. In its heyday, Angkor had a population of 1 million residents and was the spiritual center for the Khmer people until it was abandoned in the 15th century. The image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) on the 15th orbit of the space shuttle Endeavour on September 30, 1994. The image shows an area approximately 55 kilometers by 85 kilometers (34 miles by 53 miles) that is centered at 13.43 degrees north latitude and 103.9 degrees east longitude. The colors in this image were obtained using the following radar channels: red represents the L-band (horizontally transmitted and received); green represents the L-band (horizontally transmitted and vertically received); blue represents the C-band (horizontally transmitted and vertically received). The body of water in the south-southwest corner is Tonle Sap, Cambodia's great central lake. The urban area at the lower left of the image is the present-day town of Siem Reap. The adjoining lines are both modern and ancient roads and the remains of Angkor's vast canal system that was used for both irrigation and transportation. The large black rectangles are ancient reservoirs. Today the Angkor complex is hidden beneath a dense rainforest canopy, making it difficult for researchers on the ground to study

    In order to investigate the status of intestinal helminthic infections in Cambodia, epidemiological surveys were carried out on a national scale, including 19 provinces. A total of 32,201 fecal samples were collected from schoolchildren and adults between 2006 and 2011 and examined once by the Kato-Katz thick smear technique. The overall egg positive rate of intestinal helminths was 26.2%. The prevalence of hookworms was the highest (9.6%), followed by that of Opisthorchis viverrini/minute intestinal flukes (Ov/MIF) (5.7%), Ascaris lumbricoides (4.6%), and Trichuris trichiura (4.1%). Other types of parasites detected were Enterobius vermicularis (1.1%), Taenia spp. (0.4%), and Hymenolepis spp. (0.2%). The northwestern regions such as the Siem Reap, Oddar Meanchey, and Banteay Meanchey Provinces showed higher prevalences (17.4-22.3%) of hookworms than the other localities. The southwestern areas, including Koh Kong and Preah Sihanouk Provinces showed higher prevalences of A. lumbricoides (17.5-19.2%) and T. trichiura (6.1-21.0%). Meanwhile, the central and southern areas, in particular, Takeo and Kampong Cham Provinces, showed high prevalences of Ov/MIF (23.8-24.0%). The results indicate that a considerably high prevalence of intestinal helminths has been revealed in Cambodia, and thus sustained national parasite control projects are necessary to reduce morbidity due to parasitic infections in Cambodia.

    Objective Antibiotic resistance is a prominent public and global health concern. We investigated antibiotic use in children by determining the proportion of unselected children with antibacterial activity in their urine attending a paediatric outpatient department in Siem Reap, Cambodia. Methods Caregiver reports of medication history and presence of possible infection symptoms were collected in addition to urine samples. Urine antibiotic activity was estimated by exposing bacteria to urine specimens, including assessment against multiresistant bacteria previously isolated from patients in the hospital (a methicillin-resistant Staphylococcus aureus (MRSA), a multiresistant Salmonella typhi and an extended-spectrum β-lactamase (ESBL)-producing Escherichia coli isolate). Results Medication information and urine were collected from 775 children. Caregivers reported medication use in 69.0% of children in the preceding 48 h. 31.7% samples showed antibacterial activity; 16.3% showed activity against a local multiresistant organism. No specimens demonstrated activity against an ESBL-producing E. coli. Conclusions Antibiotics are widely used in the community setting in Cambodia. Parents are often ill-informed about drugs given to treat their children. Increasing the regulation and training of private pharmacies in Cambodia may be necessary. Regional surveillance of antibiotic use and resistance is also essential in devising preventive strategies against further development of antibiotic resistance, which would have both local and global consequences.

    Background No population-based studies have directly compared the long-term health and mental health outcomes of conflict- versus non-conflict-affected communities from the same ethnic background. Aims To identify and compare levels of psychiatric morbidity between a traumatized and non-traumatized civilian community; to investigate the long-term impact of mass violence. Methods Double-stratified community surveys in Siem Reap and Surin provinces were conducted by highly qualified Cambodian interviewers using culturally validated survey instruments with known psychometric properties. These included Cambodian versions of the Hopkins Symptom Checklist-25, the Harvard Trauma Questionnaire and the Medical Outcome Study Short Form. Results Siem Reap and Surin respondents experienced 12,266 and 621 major trauma events, respectively; 745 (76.2%) Siem Reap respondents and six (0.6%) Surin respondents reported torture events; 499 (49.5%) Siem Reap respondents and 203 (19.7%) Surin respondents met the clinical threshold for depression (OR 4.01, 95% CI 3.29–4.88); 204 (20.6%) Siem Reap respondents and 23 (2.2%) Surin respondents met the clinical threshold for post-traumatic stress disorder (PTSD) (OR 11.39, 95% CI 7.3–17.7).The MOS physical disability was higher in Siem Reap versus Surin respondents (74 (7.5%) vs 13 (1.3%), χ2 = 47.4 df = 1, p < .001). Health status was poorest among Siem Reap respondents when compared with Surin respondents (mean score 1.59 vs 0.59, respectively; t = 19.85 df = 2018, p < .001). Path analysis reveals that recent and past extreme violence are associated with the health and mental health status of the Siem Reap community. Conclusion After 25 years, the Khmer civilian population that experienced the Pol Pot genocide continues to suffer psychiatric morbidity and poor health. PMID:23396287

    The aim of this study is to report the experiences of three groups of Australian undergraduate nursing and midwifery students undertaking an international learning experience in Cambodia. Relying on an interpretative research design using qualitative content analysis, data were drawn from a sub-group of undergraduate third-year bachelor and dual degree nursing/midwifery students at a Queensland university, Australia. Students from a clinical placement in Siem Reap, Cambodia for a 4-week period in the January of 2010-2012 completed a formal expression of interest, and at three time intervals a questionnaire comprising open-ended questions. The evaluation by the undergraduate nursing/midwifery students of the clinical experience in Cambodia is understood through two core themes: global citizen/better citizen, personal/professional development. The findings have implications for university curriculum developers interested in the internationalization of nursing and midwifery programmes to ensure students are well equipped to practice in diverse multicultural and global health systems.

    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 <15 years were observed over the study period. A population-based risk factor analysis found that access to water within households and increasing distance from Tonle Sap Lake were protective. Spatial mapping and WGS provided additional resolution for these findings, and confirmed that proximity to the lake was associated with discrete spatiotemporal disease clusters. We confirmed the dominance of MDR H58 S. Typhi in this population, and found substantial evidence of diversification (at least seven sublineages) within this single lineage. We conclude that there is a substantial burden of pediatric 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.

    Introduction Recognizing transgender individuals have a high risk of HIV acquisition, and to inform policies and programming, we conducted an HIV prevalence and risk behaviors survey among transgender individuals in Cambodia. Methods Cross-sectional survey using a respondent driven sampling method with self-administered audio-computer assisted interviews. HIV testing was performed prior to the questionnaire with results available immediately after. Eligible participants were ≥18 years, identified as male at birth and self-identified/expressed as a different gender, and reported having sex with at least one male partner in past year. From six major urban centers of Cambodia, 891 transgender individuals were recruited. Results The majority of the 891 participants self-identified as third gender or female (94.5%), were young (median age 23, IQR [20–27]), had secondary education or higher (80.5%), not married (89.7%), and employed (90.2%). The majority had first sex before 18 years (66.8%), with a male (79.9%), 37.9% having been paid or paying for this first sex. The rate of HIV positivity among participants was found to be 4.15%. Consistent condom use with male and female partners was low with all partner types, but particularly low with male partners when paying for sex (20.3%). The majority of participants reported having experienced discrimination in their lifetime (54.8%) and 30.3% had been assaulted. Multivariate analysis revealed that older age (adjusted OR = 14.73 [4.20, 51.67] for age 35–44 and adjusted OR = 7.63 [2.55, 22.81] for age 30–34), only having a primary school education or no schooling at all (adjusted OR = 2.62 [1.18, 5.80], being a resident of Siem Reap (adjusted OR = 7.44 [2.37,23.29], receiving payment at first sex (adjusted OR = 2.26 [1.00, 5.11], having sex during/after using drugs (adjusted OR = 2.90 [1.09,7.73]), inconsistent condom use during last anal sex (adjusted OR = 3.84 [1.58, 9.33]), and reporting low self-esteem (adjusted OR

    Objective To explore risk factors associated with induced abortion among sexually active female entertainment workers (FEWs) in Cambodia. Design Cross-sectional study. Setting Phnom Penh and Siem Reap, Cambodia. Participants This study included 556 FEWs aged 18–47 years randomly selected from entertainment establishments in the two cities in 2014 using a two-stage cluster sampling method. Data were collected through face-to-face interviews using a structured questionnaire. Primary outcome measure History of induced abortion during the time working as a FEW. Results Of the total sample, 45.6% reported currently using a contraceptive method with condom (42.4%) being the most common method, followed by pills (25.6%). One-fourth (25%) of the respondents reported having been pregnant at least once, and 21.4% reported having at least one induced abortion during the time working as a FEW. After controlling for other covariates in a multivariate logistic regression model, FEWs with a history of induced abortion remained significantly more likely to be currently working in a karaoke bar (AOR=1.75, 95% CI 1.10 to 2.78), to have worked longer as a FEW (AOR=1.42, 95% CI 1.06 to 1.43), to have had a greater number of sexual partners in the past 12 months (AOR=1.86, 95% CI 1.02 to 1.54), to be currently using a contraceptive method (AOR=1.52, 95% CI 1.01 to 2.29), to be able to find condoms when they needed them (AOR=2.03, 95% CI 1.09 to 3.82), and to report inconsistent condom use with non-commercial partners in the past 3 months (AOR=1.62, 95% CI 1.06 to 3.44). Conclusions This study highlights the high rates of unwanted pregnancies that ended in induced abortions among FEWs in Cambodia. Access of FEWs to quality sexual and reproductive healthcare services is deemed a high priority. Integrated interventions to improve sexual and reproductive health among these vulnerable women should be tailored to reach the most-at-risk groups. PMID:26231754

    High aspect ratio structures are often present in MEMS devices and EPON SU-8 is often used to produce such structures because of its low cost. It is essential to know the mechanical properties of SU-8 for producing reliable MEMS products. However, the mechanical properties of SU-8 may depend on the manufacturing process and the size of the structure, which is in the micron domain. Hence, one needs to test specimens that are similar in size to MEMS structures to determine if the mechanical properties change with processing protocol. In this work, the authors applied the newly developed technique SIEM (Speckle Interferometry with Electron Microscopy) to the determination of SU-8's mechanical properties.

    Background 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. Methods 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. Results 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). Conclusions We found risky sexual behaviors to be considerably high among MSM in this

    The wealth and value of organizations are increasingly based on intellectual capital. Although acquiring talented individuals and investing in employee learning adds value to the organization, reaping the benefits of intellectual capital involves translating the wisdom of employees into reusable and sustained actions. This requires a culture that creates employee commitment, encourages learning, fosters sharing, and involves employees in decision making. An infrastructure to recognize and embed promising and best practices through social networks, evidence-based practice, customization of innovations, and use of information technology results in increased productivity, stronger financial performance, better patient outcomes, and greater employee and customer satisfaction.

    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. PMID:12159246

    Cambodia is a developing south-east Asian country located in the fertile Mekong delta. Its recent past has been complicated by European colonialism and internal conflict. Health including mental health services are limited and sparse in regional and rural areas. Very constrained public mental health facilities and services are hampered by a shortage of a skilled workforce and insufficient training programs. The recent formation of the Mental Health Association of Cambodia promises to be a positive step forward in promoting mental health throughout the country. PMID:23051055

    In order to improve students’ motivation, the SIEM (School of Information Environment Method) which is the education method for the introduction of the computer programming education was developed. We focus on students’ motivation, and we have measured students’ motivation as the educational effects. After the SIEM was developed in the School of Information Environment, it applied to introduction to the computer programming education in the School of Engineering Evening Division at the Department of Electrical and Electronic Engineering. It is effective for the improvement of students’ motivation. By adding the Customer Satisfaction Analysis to the SIEM Analysis, it was able to clarify the priority level of the SIEM assessment item. In this paper, we describe results of the Customer Satisfaction Analysis.

    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.

    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.

  12. Myths about AIDS in Cambodia.

    PubMed

    Nariddh, M C

    1994-08-01

    HIV has been reported in the capital city of Cambodia, Phnom Penh, as well as in the northwestern provinces of Banteay Meanchey, Battambang, Pursat, and Kompong Chhnang. Unofficial reports indicate the presence of HIV in three northeastern provinces. According to World Health Organization data, 382 people were infected with HIV in Cambodia as of March 1994, but the national AIDS program estimates that 2000-4000 Cambodians may be HIV-seropositive. Small surveys in 1992 identified HIV infection rates to be 4.5% among patients of sexually transmitted disease (STD) clinics and 9.2% among prostitutes. A seroprevalence rate of 4.3% was found in 1993 among clients of STD clinics and others requesting HIV testing. These rather marked levels of infection exist in Cambodia even though HIV was first identified in the country as recently as 1991 among screened blood from volunteer donors. By December 1993, the rate of positive results from blood donors had increased to 1.97%.; the rate of infection among blood donors is expected to double to approximately 4% in 1994. People in Cambodia variously believe that AIDS is nonexistent, AIDS is a problem of other countries, can be transmitted by mosquitoes, healthy people do not have AIDS, a cure exists for AIDS, AIDS can be contracted only from prostitutes, AIDS is the most severe state of syphilis, and AIDS is only a propaganda ploy of condom producers to market their products. It is therefore proving extremely difficult to convince people that AIDS is a truly threatening disease against which they should protect themselves, especially when symptoms are rarely present during the early stage of infection. Health education campaigns, videos, posters, and accurate reporting in the media will, however, help change minds and hopefully induce HIV-preventive behaviors. Of interest, the article notes that virtually every prostitute in Cambodia has at least two-three STDs. PMID:12345639

  13. Health care clinics in Cambodia.

    PubMed

    Wollschlaeger, K

    1995-04-01

    Under the Pol Pot Khmer Rouge regime, most physicians with clinical experience were either killed or fled the country. The few practitioners who managed to survive were forced to hide their knowledge; much of that knowledge and experience is now lost. As part of a general process of national rehabilitation, Cambodia has trained since the 1980s hundreds of physicians and physician assistants. There were 700 physicians, 1300 physician assistants, and 4000 nurses in the country by 1992. Problems do, however, remain with medical education in Cambodia. In particular, the medical texts and lectures are in French, a language which very few of the younger generation speak; instructional texts are designed to meet the needs of developing nations, not a rehabilitating one like Cambodia; emphasis is upon curative health care, hospitals, and vertical programs instead of primary and preventive health care; Cambodian physicians are used to a system based upon the division of patients by ability to pay instead of by age, disease, or need; corruption has grown as the cost of living has outstripped the level of official salaries; and there is neither professional contact, feedback, nor program evaluation within health care programs. The authors is a resident in obstetrics and gynecology at the University of Chicago who worked at two clinics during a stay in Phnom Penh. She recommends that instead of simply training more doctors, these training-related problems should be addressed, including a revision of the curriculum to include both primary health care medicine and psychiatry. Moreover, people in Cambodia need to be taught the importance of preventive health care, which should then reduce the number of visits to physicians. This process will be accomplished more effectively with the cooperation of physicians, the government, nongovernmental organizations, and international organizations associated with health care.

    2011-01-01

    Drawing on microlevel research with men and women of differing ages living in rural and urban Siem Reap (home to the global heritage and tourist site of Angkor), this article focuses on the key discourses and practices that men and women draw on to (de)stabilize putatively traditional ideals of Cambodian womanhood and to (re)situate them in the contemporary period. Mapping the complex ways that people represent, make sense of, and respond to prerevolutionary cultural norms of female behavior in a very different era (with particular, though not exclusive, attention paid to mobility and education), the article demonstrates how deeper ideological changes concerning women’s relationship to Khmer tradition will have to accompany the surface reordering of Cambodian gender relations if equality between women and men is to be achieved. Until then, the ideal woman in contemporary Cambodian society is ultimately one who can creatively negotiate and balance the multiple demands placed on her by society, family, and self.

    Following their participation in a United Nations peacekeeping operation in Cambodia (1992-1993), Dutch veterans complained of symptoms similar to those reported by Gulf War veterans. The authors conducted a matched case-control study to evaluate 76 symptomatic and 32 matched asymptomatic Cambodia veterans on the basis of data collected by postal questionnaire. The number of symptomatic veterans who reported having used insect repellants that contained N,N,-diethyl-meta-toluamide (DEET) during the mission in Cambodia was significantly higher, compared with asymptomatic veterans. The percentage of veterans who reported feeling ill following brief exposures to chemicals such as paint or pesticides was equal in both groups, but the percentage was low compared with the results of other studies of Multiple Chemical Sensitivity Syndrome. The current study was limited by self-report and time delay (potential recall bias) between deployment to Cambodia and the time of survey. Nevertheless, the study results did not support the hypothesis that symptoms in the total group of Cambodia veterans could be related to Multiple Chemical Sensitivity Syndrome. PMID:15859508

    In 2003 the Government of Cambodia officially began to recognise that harm reduction was an essential approach to preventing HIV among people who use drugs and their sexual partners. Several programs aiming to control and prevent HIV among drug users have been implemented in Cambodia, mostly in the capital, Phnom Penh. However, there have been ongoing tensions between law enforcement and harm reduction actors, despite several advocacy efforts targeting law enforcement. This study attempts to better understand the implementation of harm reduction in Cambodia and how the policy environment and harm reduction program implementation has intersected with the role of law enforcement officials in Cambodia.

    Although no verifiable hard data regarding the rate of nation-wide deforestation in Cambodia exists, it is understood that on account of increasing logging activities, uncontrolled forest fires, increased demand for agricultural land and fuel wood for charcoal production and other domestic usage, the rates of deforestation and the degradation of existing forests will continue to be on the rise if no effective policy and management plans are established soon. There now seems to be international recognition and acceptance of the fact that unless the impact of human activities are incorporated into forestry management plans, the problems of deforestation in the world`s poorest regions will continue unabated. The depletion of this natural resource brings about complex changes in the environment which results in such phenomenon as global warming. Sound forest policies and management practices are central to the global warming solution. Without these, human survival remains, potentially, threatened. An essential key to the development of such policies and management practices lies in the identification of the problems related to the forests. In this process of identification and subsequent concrete actions in restoring Cambodia`s forest policies and management practices, the Royal government of Cambodia has been assisted and supported by the international community through organizations and agencies. The examine and appraisal of such assistance and the strategies and efforts of the Royal Government of Cambodia, is the main theme of this paper.

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

    Determining the magnitude of the thalassemia problem in a country is important for implementing a national prevention and control program. In order to acquire accurate thalassemia prevalence data, the gene frequency of α- and β-thalassemia (α- and β-thal) in different regions of a country should be determined. The molecular basis of thalassemia in Cambodia was performed by polymerase chain reaction (PCR)-based techniques in a community-based cross-sectional survey of 1631 unrelated individuals from three regions, Battambang, Preah Vihear and Phnom Penh. Thalassemia mutations were detected in 62.7% of the three studied population of Cambodia. Hb E (HBB: c.79G > A) was the most common β-globin gene mutation with a frequency ranging from 0.139 to 0.331, while the most frequent α-globin gene mutation was the -α(3.7) (rightward) deletion (0.098-0.255). The other frequencies were 0.001-0.003 for β-thal, 0.008-0.011 for α-thal-1 (- -(SEA)), 0.003-0.008 for α-thal-2 [-α(4.2) (leftward deletion)], 0.021-0.044 for Hb Constant Spring (Hb CS, HBA2: c.427T > C) and 0.009-0.036 for Hb Paksé (HBA2: c.429A > T). A regional specific thalassemia gene frequency was observed. Preah Vihear had the highest prevalence of Hb E (55.9%), α-thal-2 (24.0%) and nondeletional α-thal (15.1%), whereas Phnom Penh had the lowest frequency of thalassemia genes. Interestingly, in Preah Vihear, the frequency of Hb Paksé was extremely high (0.036), almost equivalent to that of Hb CS (0.044). Our results indicate the importance of micromapping and epidemiology studies of thalassemia, which will assist in establishing the national prevention and control program in Cambodia. PMID:27117566

    This spaceborne radar image shows the city of Phnom Penh, the capital of Cambodia. Phnom Penh lies at the confluence of the Mekong River and the Basak Sab. The city was originally established in 1434 to succeed Angkor Thom as capital of the Khmer Nation. Phnom Penh is the bright blue and orange area west of the rivers, near the center of the image. The red, light blue and purple colors indicate differences in vegetation height and structure. Radar images like this one are being used by archaeologists to investigate ruins in the Angkor area in northern Cambodia. This image was acquired by Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) onboard the space shuttle Endeavour on April 15, 1994. The image is 27 kilometers by 27 kilometers (17 miles by 17 miles) and is centered at 11.5 degrees north latitude, 105.0 degrees East longitude. North is toward the upper right. The colors are assigned to different radar frequencies and polarizations of the radar as follows: red is L-band, horizontally transmitted and received; green is L-band, horizontally transmitted and vertically received; and blue is C-band, horizontally transmitted and vertically received. SIR-C/X-SAR, a joint mission of the German, Italian, and United States space agencies, is part of NASA's Mission to Planet Earth.

  17. Cambodia: the women want justice and peace.

    PubMed

    1999-01-01

    Refugees and internally displaced people are an unfortunate and inevitable consequence of war. Among these, women refugees are most vulnerable to sexual violence as they go through various stages of displacement. During the war in Cambodia, women refugees experienced sexual violence in the form of rape, gang rape, sexual exploitation, and forced prostitution. This report presents a summary of a testimony by Yi Leang Eng, a Cambodian woman refugee, on her experiences during the war. According to her, violations of rape happened inside and outside the refugee camps everyday, relegating the violence as a normal occurrence. In this regard, nongovernmental organizations and governments are urged to cooperate and insist that perpetrators of such crimes must be punished and such practices must be immediately stopped. In addition, the issue of supporting women survivors and ensuring that they are given justice should also be discussed. Moreover, for the women survivors themselves, the welfare of their families should be top priority. PMID:12179106

    We conducted a survey in Cambodia in 2000 on henipavirus infection among several bat species, including flying foxes, and persons exposed to these animals. Among 1,072 bat serum samples tested by enzyme-linked immunosorbent assay, antibodies reactive to Nipah virus (NiV) antigen were detected only in Pteropus lylei species; Cynopterus sphinx, Hipposideros larvatus, Scotophilus kuhlii, Chaerephon plicata, Taphozous melanopogon, and T. theobaldi species were negative. Seroneutralization applied on a subset of 156 serum samples confirmed these results. None of the 8 human serum samples was NiV seropositive with the seroneutralization test. One virus isolate exhibiting cytopathic effect with syncytia was obtained from 769 urine samples collected at roosts of P. lylei specimens. Partial molecular characterization of this isolate demonstrated that it was closely related to NiV. These results strengthen the hypothesis that flying foxes could be the natural host of NiV. Surveillance of human cases should be implemented. PMID:16022778

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

  20. Pulmonary melioidosis in Cambodia: A prospective study

    PubMed Central

    2011-01-01

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

    Our program attempted to integrate community mental health in primary care settings in Cambodia and to evaluate the effects of training on local providers. The training program underwent an extensive evaluation to determine its impact on the mental health knowledge, confidence in performing medical and psychiatric procedures, skills and attitudes of its trainees. One hundred four Cambodian primary care practitioners (PCPs) were trained in a primary care setting in Siem Reap, Cambodia, over a 2-year period. There was a significant improvement in PCPs' confidence in all clusters of medical and psychiatric procedures (counseling, medical evaluation, prescribing medications, psychiatric diagnosis, assessing risk for violence, traditional treatments, and treating trauma victims) comparing baseline to posttraining and baseline to 2-year follow-up (p < 0.05). Only confidence in prescribing psychotropic medications improved from posttraining to 2-year follow-up. This study supports the feasibility of training PCPs in a culturally effective manner in a postconflict society. PMID:16082300

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

    2011-01-01

    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.

    Cambodia is a small, poor, and sparsely-populated country between Vietnam and Thailand, which is making a slow recovery from a long history of conflict. 80% of its 11.4 million people live by subsistence farming; rice is their main crop. Infant mortality is 89.4/1000, and 12% of children die before the age of 5 years. Life expectancy is around 50 years, and about 45,000 Khmers (Cambodians) are missing at least one limb from a 30 year deposit of landmines and dumping unexploded ordinance. Despite a decade of concerted effort by the international community to improve Cambodia's prospects, disease and poverty still define life for most of the population. In April, 2002, I visited Cambodia for the fourth time in 10 years, to see how medical aid projects were faring in particular, and to assess whether the past decade of international aid and intervention has improved the provision of health care for Khmers.

    Difficulties in accessing high-quality data on trace gas fluxes and performance of bioenergy/bioproduct feedstocks limit the ability of researchers and others to address environmental impacts of agriculture and the potential to produce feedstocks. To address those needs, the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) and REAP (Renewable Energy Assessment Project) research programs were initiated by the USDA Agricultural Research Service (ARS). A major product of these programs is the creation of a database with greenhouse gas fluxes, soil carbon stocks, biomass yield, nutrient, and energy characteristics, and input data for modeling cropped and grazed systems. The data include site descriptors (e.g., weather, soil class, spatial attributes), experimental design (e.g., factors manipulated, measurements performed, plot layouts), management information (e.g., planting and harvesting schedules, fertilizer types and amounts, biomass harvested, grazing intensity), and measurements (e.g., soil C and N stocks, plant biomass amount and chemical composition). To promote standardization of data and ensure that experiments were fully described, sampling protocols and a spreadsheet-based data-entry template were developed. Data were first uploaded to a temporary database for checking and then were uploaded to the central database. A Web-accessible application allows for registered users to query and download data including measurement protocols. Separate portals have been provided for each project (GRACEnet and REAP) at nrrc.ars.usda.gov/slgracenet/#/Home and nrrc.ars.usda.gov/slreap/#/Home. The database architecture and data entry template have proven flexible and robust for describing a wide range of field experiments and thus appear suitable for other natural resource research projects.

    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.

    Though the consequences of nutritional iodine deficiency have been known for a long time, in Cambodia its elimination has only become a priority in the last 18 years. The Royal Government of Cambodia initiated the National Sub-Committee for Control of Iodine Deficiency Disorders in 1996 to fight this problem. Using three different surveys providing information across all provinces, we examined the compliance of salt iodization in Cambodia over the last 6 years. Salt samples from the 24 provinces were collect at the household level in 2008 (n = 566) and 2011 (n = 1275) and at the market level in 2014 (n = 1862) and analysed through a wavelength spectrophotometer for iodine content. According to the samples collected, the median iodine content significantly dropped from 22 mg/kg (25th/75th percentile: 2/37 mg/kg) in 2011 to 0 mg/kg in 2014 (25th/75th percentile: 0/8.9 mg/kg) (p < 0.001). The proportion of non-iodized salt within our collected salt drastically increased from 22% in 2011 to 62% in 2014 (p < 0.001). Since the international organizations ceased to support the procurement of iodine, the prevalence of salt compliant with the Cambodian declined within our samples. To date, the current levels of iodine added to tested salt are unsatisfactory as 92% of those salts do not meet the government requirements (99.6% of the coarse salt and 82.4% of the fine salt). This inappropriate iodization could illustrate the lack of periodic monitoring and enforcement from government entities. Therefore, government quality inspection should be reinforced to reduce the quantity of salt not meeting the national requirement. PMID:26035245

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

    The HIV epidemic in Cambodia is one of the most extensive in Asia. Meningitis accounts for a substantial proportion of HIV-related morbidity and mortality in Cambodia. A retrospective chart review was performed to identify the clinical and spinal fluid characteristics of patients undergoing spinal tap at an AIDS referral hospital in Phnom Penh, Cambodia during a 16-month period. Of 932 charts reviewed, 89 met criteria for analysis. Overall mortality was 49.4%. Cryptococcus was the most commonly identified pathogen (83%), followed by mycobacteria (8%). No pathogen was identified in 9% of charts reviewed. In hospital mortality was similar in all groups. PMID:14769172

    2015-01-01

    After catastrophic events in which people’s survival has been threatened, as happened during the Khmer Rouge regime in Cambodia 1975–1979, some continue to suffer from painful mental symptoms. Surveys carried out in Cambodia based on Western diagnostic categories have found a high prevalence of posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in the population. This study explored Cambodian approaches to healing trauma, examining the ways in which Cambodians appeal to elements of Buddhism in their efforts to calm their minds, situating this mode of coping in the context of broader Khmer Buddhist practice and understandings. Western psychology may have much to learn from local, contextualised methods of dealing with the aftermath of trauma, including Khmer understandings of distress and approaches to relief. Methods of assessment and treatment of distress cannot be transposed wholesale from one cultural setting to another but require considerable cultural adaptation. This kind of cultural interchange may give rise to innovative, hybrid discourses and methods that may have much to offer in the support of victims of organised violence. PMID:25653141

    A 2014 national assessment of salt iodization coverage in Cambodia found that 62% of samples were non-iodized, suggesting a significant decline in daily iodine intakes. The Cambodian Micronutrient Survey conducted in 2014 (CMNS-2014) permitted obtaining national data on urinary iodine concentrations (UIC) to assess iodine status and whether iodized salt use had an impact. Urine samples were collected from mothers (n = 736) and children (n = 950). The median UIC was 63 µg/L and 72 µg/L in mothers and children respectively. More than 60% of mothers and their children had a UIC < 100 µg/L, thereby indicating a serious public health problem. Iodine status was significantly lower among mothers and children living in rural areas, belonging to the poorest socioeconomic category, or living in a household not using iodized salt. The limited enforcement of the legislation for iodized salt has resulted in a major decrease in the prevalence of iodized salt, which in turn has compromised iodine status in Cambodia. It is essential for the government to enhance enforcement of the iodized salt legislation, and implement short term strategies, such as iodine supplementation, to prevent an increase of severe complications due to iodine deficiency in the Cambodian population.

    Global expansion of antiretroviral therapy (ART) programmes for people living with HIV is the largest public health undertaking to date. Antiretroviral therapy adherence drives individual and programme outcomes, yet little is known regarding the determinants of these behaviours. We investigated beliefs and practices associated with ART use in Cambodia. In-depth interviews were conducted during 2005 with 27 people living with HIV who were recruited using a theoretical sampling strategy and analysed in Khmer and English using an inductive approach to code data and identify themes. Limited access to ART generated a sense of ART as rare and precious, with access granted by doctors once patients proved themselves dependable. The social construction of ART use was strict, precise and modern with ritualistic preparation and dosing procedures. Experiences of life-saving efficacy in self and others built a deep sense of trust. For many, ART was simply equated to life. Antiretroviral therapy dosing was prioritized and supported by an ever-present sense of remembering, reminder devices and social networks. Healthcare workers set norms and provided various forms of adherence support. Antiretroviral therapy use in Cambodia is shaped by the relationship between individuals and social and healthcare networks that set, encourage and enforce precise norms of ART use. PMID:21516534

    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. PMID:22124701

    In this paper, a process established with a positive-tone chemically amplified resist (CAR) from TOK REAP200 and Fujifilm Arch FEP171 and 50kV MEBES system is discussed. This TOK resist is developed for raster scan 50 kV e-beam systems. It has high contrast, good coating characteristics, good dry etch selectivity, and high environmental stability. In the mask industries, the most popular positive tone CAR is FEP171, which is a high activation energy type CAR. REAP (Raster E-beam Advanced Process) 200 is low activation energy type and new acetal protecting polymer. In this study, we compared to these different type resists in terms of contrast, PAB and PEB latitude, resist profile, footing, T-topping, PED stability, LER, Global CDU (Critical Dimension Uniformity) and resolution. The REAP200 Resist obtained 75nm isolated lines and spaces, 90nm dense patterns with vertical profile, and a good stability of delay time.

    2013-01-01

    Background Cambodia has very high rates of tuberculosis and smoked tobacco use among adults. Efforts to control both tobacco use and tuberculosis in Cambodia need to be informed by nationally representative data. Our objective is to examine the relation between daily cigarette smoking and lifetime tuberculosis (TB) history in a national sample of adults in Cambodia. Methods In 2011, a multi-stage, cluster sample of 15,615 adults (ages 15 years and older) from all regions of Cambodia were administered the Global Adult Tobacco Survey by interviewers from the National Institute of Statistics of Cambodia. Results Our findings include: 1) among daily smokers, a significant positive relation between TB and number of cigarettes smoked per day (OR = 1.70 [95% CI 1.01, 2.87]) and pack-years of smoking (OR = 1.53 [95% CI 1.05, 2.25]) 2) a non-significant 58% increase in odds of ever having being diagnosed with TB among men who smoked manufactured cigarettes (OR = 1.58 [95% CI 0.97, 2.58]). Conclusion In Cambodia, manufactured cigarette smoking was associated with lifetime TB infection and the association was most evident among the heaviest smokers (> 1 pack per day, > 30 pack years).

    Labor migration is thought to have significant mental and physical health impacts, given the risks for exploitation and abuse of migrant workers, particularly among those in semiskilled and unskilled positions, although empirical data are limited. This qualitative study, conducted in July 2010 in Banteay Meanchey Province, Cambodia, focused on psychosocial and mental health signs and symptoms associated with labor migration among Cambodian migrant workers to Thailand. Two qualitative methods identified a number of mental health problems faced by Cambodian migrant workers in Thailand, including the presence of anxiety and depression-like problems among this population, described in local terminology as pibak chet (sadness), keut chreun (thinking too much), and khval khvay khnong chet (worry in heart). Key informants revealed the extent to which psychosocial well-being is associated with conditions of poverty, including debt and lack of access to basic services. PMID:24566505

    We investigated infection of rodents and shrews by Leptospira spp. in two localities of Cambodia (Veal Renh, Kaev Seima) and in four types of habitat (forests, non-flooded lands, lowland rain-fed paddy fields, houses) during the wet and the dry seasons. Habitat preference was common, and rodent and shrew species were found only in houses or in rain-fed paddy fields or in forests. Among 649 small mammals trapped belonging to 12 rodent species and 1 shrew species, 71 of 642 animals tested were carriers of Leptospira according to the 16S ribosomal RNA marker used. Rodent infection was higher in low-slope locations, corresponding to rain-fed paddy fields, especially in the rainy season and in Kaev Seima. Rodents (Rattus exulans) and shrews (Suncus murinus) inhabiting households showed significantly low levels of infections, whereas rodents living in and near to forests (shrubby wasteland, orchards) showed high levels of infection.

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

    The capacity to care for the critically ill has long been viewed as a fundamental element of established and comprehensive health care systems. Extending this capacity to health care systems in low- and middle-income countries is important given the burden of disease in these regions and the significance of critical care in overall health system strengthening. However, many practicalities of improving access and delivery of critical care in resource-limited settings have yet to be elucidated. We have initiated a program to build capacity for the care of critically ill patients in one low-income Southeast Asian country, Cambodia. We are leveraging existing international academic partnerships to enhance postgraduate critical care education in Cambodia. After conducting a needs assessment and literature review, we developed a three-step initiative targeting training in mechanical ventilation. First, we assessed and revised the current resident curriculum pertaining to mechanical ventilation. We addressed gaps in training, incorporated specific goals and learning objectives, and decreased the hours of lectures in favor of additional bedside training. Second, we are incorporating e-learning, e-teaching, and e-assessment into the curriculum, with both live, interactive and independent, self-paced online instruction. Third, we are developing a train-the-trainer program defined by bidirectional international faculty exchanges to provide hands-on, case-based, and bedside training to achieve competency-based outcomes. In targeting specific educational needs and a key population-the next generation of Cambodian intensivists-this carefully designed approach should address some existing gaps in the health care system and hopefully yield a lasting impact.

    Objective: To determine the frequency and characteristics of patients with unsuccessful tuberculosis (TB) treatment. Methods: Random selection of TB case registers among all treatment units in Cambodia, two provinces in China, and Viet Nam. The data of two calendar years were analyzed to assess unsuccessful outcomes and their time of occurrence. Results: Among the 33 309 TB patients, treatment was unsuccessful in respectively 10.1%, 3.0% and 9.1% of patients in Cambodia, China and Viet Nam. The risk of death was highest in Cambodia, higher among males than females, increased with age, and was more common among retreatment cases than new cases, and among patients with a high than a low sputum smear microscopy grade. Half of all deaths occurred in the first 2 months in Cambodia and within 11 weeks in China and Viet Nam. Median time to default was 3 months in Cambodia and Viet Nam, and about 2 months in China. Conclusions: Treatment was highly successful in the three study countries, with a low proportion of death and default. As the majority of defaulting occurs at the beginning of treatment, all countries should critically review their current policy of treatment support in this period. PMID:26392939

    2002-01-01

    This image of Ancharn Kuy, Cambodia, was taken by NASA's Airborne Synthetic Aperture Radar (AIRSAR). The image depicts an area northwest of Angkor Wat. The radar has highlighted a number of circular village mounds in this region, many of which have a circular pattern of rice fields surrounding the slightly elevated site. Most of them have evidence of what seems to be pre-Angkor occupation, such as stone tools and potsherds. Most of them also have a group of five spirit posts, a pattern not found in other parts of Cambodia. The shape of the mound, the location in the midst of a ring of rice fields, the stone tools and the current practice of spirit veneration have revealed themselves through a unique 'marriage' of radar imaging, archaeological investigation, and anthropology.

    Ancharn Kuy is a small village adjacent to the road, with just this combination of features. The region gets slowly higher in elevation, something seen in the shift of color from yellow to blue as you move to the top of the image.

    The small dark rectangles are typical of the smaller water control devices employed in this area. While many of these in the center of Angkor are linked to temples of the 9th to 14th Century A.D., we cannot be sure of the construction date of these small village tanks. They may pre-date the temple complex, or they may have just been dug ten years ago!

    The image dimensions are approximately 4.75 by 4.3 kilometers (3 by 2.7 miles) with a pixel spacing of 5 meters (16.4 feet). North is at top. Image brightness is from the C-band (5.6 centimeters, or 2.2 inches) wavelength radar backscatter, which is a measure of how much energy the surface reflects back toward the radar. Color is used to represent elevation contours. One cycle of color; that is going from blue to red to yellow to green and back to blue again; corresponds to 10 meters (32.8 feet) of elevation change.

    Several studies indicate that douching has few benefits but numerous adverse health outcomes, including increased risk for sexually transmitted infections and HIV. No published study explores douching practices among Cambodian female sex workers. This report provides preliminary data about the prevalence and frequency of douching among female sex workers in Phnom Penh, Cambodia. Survey data were obtained from 81 female sex workers who were taken into custody due to engagement in commercial sex from March to June 2011. Results showed that 91% of participants douched. The mean numbers of times douched before sex and after sex per 10 sex episodes were 4.43 (SD = 3.87) and 4.63 (SD = 3.94), respectively. Half of the participants thought that douching could help to prevent sexually transmitted infections including HIV; 24% were unsure about this. Usually, douching after sex was associated with ever obtaining an HIV test (p = .012) and was marginally associated (although not statistically significant) with a higher average number of clients per week (p =. 063) and consistent condom use with clients (p = .053). This suggests that these practices may be related to individual perceptions of sexually transmitted infections/HIV risk or susceptibility. Given the commonness of douching and related misperceptions among Cambodian female sex workers, future studies and interventions are needed to prevent adverse health problems. PMID:24810219

    We investigated relationship of arsenicosis symptoms with total blood arsenic (BAs) and serum albumin (SAlb) of residents in the Mekong River basin of Cambodia. We found that arsenicosis patients had significantly higher BAs and lower SAlb than asymptomatic villagers (Mann-Whitney U test, p<0.01). Arsenicosis symptoms were found to be 76.4% (1.764 times) more likely to develop among individuals having an SAlb≤44.3gL(-1) than among those who had an SAlb>44.3gL(-1) (OR=1.764, 95% CI=0.999-3.114) and 117.6% (2.176 times) as likely to occur among those with BAs>5.73µgL(-1) than for those having BAs≤5.73µgL(-1) (OR=2.176, 95% CI=1.223-3.872). Furthermore, a significant negative correlation was also found between BAs and SAlb (rs (199)=-0.354, p<0.0001). As such, this study suggests that people with low SAlb and/or high BAs are likely to rapidly develop arsenicosis symptoms. PMID:25262072

    A total of 448 samples in five natural populations of wild rice (Oryza rufipogon) were collected in Cambodia. They were examined using 12 SSR and two chloroplast markers to evaluate the degree of variation among populations and the genetic structure within populations. In the two annual populations, the number of plants with homozygous alleles at all 12 SSR loci were high (66.3% and 79.5%), suggesting that these plants propagate mainly through self-pollination. In the three perennial populations, no individuals had all homozygous genotypes, but redundant genotypes resulted from clonal propagation were observed. Percentages of the redundant genotypes were highly varied (3.6%, 29.2% and 86.0%). This may be due to the different stable levels of environmental conditions. As for chloroplast genome, most of the wild plants showed the same chloroplast types as most Indica-type cultivars have. However, plants with different chloroplast types were maintained, even in the same population. In tropical Asian countries, many wild rice populations were observed under similar ecological conditions examined in this study. Therefore, the present results concerning population structure will be important to further elucidate genetic features of wild rice, and will also give strong clues to utilize and conserve wild natural genetic resources.

    Angkor (Cambodia) was the seat of the Khmer Empire from the 9th to 15th century AD. The site is noted for its monumental architecture and complex hydro-engineering systems, comprised of canals, moats, embankments, and large reservoirs, known as barays. We infer a 1,000-y, 14C-dated paleoenvironmental record from study of an approximately 2-m sediment core taken in the largest Khmer reservoir, the West Baray. The baray was utilized and managed from the time of construction in the early 11th century, through the 13th century. During that time, the West Baray received relatively high rates of detrital input. In the 14th century, linear sedimentation rates diminished by an order of magnitude, yielding a condensed section that correlates temporally with episodes of regional monsoon failure during the late 14th and early 15th century, recorded in tree ring records from Vietnam. Our results demonstrate that changes in the water management system were associated with the decline of the Angkorian kingdom during that period. By the 17th century, the West Baray again functioned as a limnetic system. Ecologic and sedimentologic changes over the last millennium, detected in the baray deposits, are attributed to shifts in regional-scale Khmer water management, evolving land use practices in the catchment, and regional climate change.

    In 2013, an unusual increase of paratyphoid fever cases in travellers returning from Cambodia was reported in Japan. From December 2012 to September 2013, 18 cases of Salmonella Paratyphi A infection were identified. Microbiological analyses revealed that most isolates had the same clonal identity, although the epidemiological link between these cases remains unclear. It was inferred that the outbreak was caused by a common and persistent source in Cambodia that was likely to have continued during 2014. The information of surveillance and laboratory data from cases arising in travellers from countries with limited surveillance systems should be timely shared with the country of origin.

    Cambodia is an area considered free of leishmaniasis and consequently little is known of its' phlebotomine sand fly fauna. Only six species of sand flies have previously been recorded: Sergentomyia barraudi, Sergentomyia pertubans, Sergentomyia bailyi, Sergentomyia silvatica, Sergentomyia khawi and Grassomyia indica and none belonging to the genus Phlebotomus. During an inventory carried out in Cambodia, we caught a new species, belonging to the genus Idiophlebotomus, in a cave. We describe the new species in this paper and also report three other new species for the country: Sergentomyia anodontis, Phlebotomus stantoni and Phlebotomus kiangsuensis. PMID:26655043

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

  20. An Acinetobacter trimeric autotransporter adhesin reaped from cells exhibits its nonspecific stickiness via a highly stable 3D structure

    Trimeric autotransporter adhesins (TAAs), cell surface proteins of Gram-negative bacteria, mediate bacterial adhesion to host cells and extracellular matrix proteins. However, AtaA, a TAA in the nonpathogenic Acinetobacter sp. strain Tol 5, shows nonspecific, high adhesiveness to abiotic material surfaces as well as to biotic surfaces. AtaA is a homotrimer of polypeptides comprising 3,630 amino acids and forms long nanofibers; therefore, it is too large and structurally complex to be produced as a recombinant protein. In this study, we isolated AtaA’s passenger domain (AtaA PSD), which is translocated to the cell surface through the C-terminal transmembrane domain and exhibits biological functions, using a new method. We introduced a protease recognition site and reaped AtaA nanofibers 225 nm in length from the cell surface through proteolytic cleavage with a specific protease. Biochemical and biophysical analyses of the purified native AtaA PSD revealed that it has a stable structure under alkaline and acidic conditions. Temperatures above 80 °C, which disrupted AtaA’s higher-order structure but maintained the full-length AtaA polypeptide, inactivated AtaA’s nonspecific adhesiveness, suggesting that the stickiness of AtaA requires its 3D structure. This finding refutes the widespread but vague speculation that large unfolded polypeptides readily stick to various surfaces. PMID:27305955

    This paper describes the trials of the MINEHOUND TM dual sensor, land mine detector carried out in Cambodia, Bosnia and Angola. MINEHOUND TM has been developed for use in humanitarian demining as a means of improving the efficiency of clearance operations. The trials were sponsored by the UK Department for International Development (DFID). ERA Technology Ltd conducted the trials, which were monitored by staff drawn from the countries participating in the International Test and Evaluation Programme (ITEP) for humanitarian de-mining. Experienced deminers from the Mines Advisory Group (MAG) and Norwegian Peoples Aid (NPA) used the pre-production units in live minefields. The objectives of the trial were: 1. To record information on the performance of MINEHOUND TM when used in a live minefield. 2. To determine the reduction in False Alarm Rate (FAR) that could be achieved using a dual sensor mine detector. The trials were conducted in three mine-affected countries for a period of eight weeks per country; the programme of trials ran from July 2005 to December 2005, with an additional smaller trial in late February 2006. The results of the trials showed that MINEHOUND TM achieved 100% detection of the mines encountered and an improvement in FAR of better than 5:1 compared with a basic metal detector. The trials enabled optimisation of the production design and clearly demonstrated that new technology can be brought to humanitarian clearance operations in a safe and controlled manner. As a result of the highly successful trials, Vallon and ERA will produce the MINEHOUND TM (Type number VMR1) starting in Q3 of 2006.

    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. PMID:25903454

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 light

    The Real Engagement in Active Problem Solving (REAPS) model was developed in 2004 by C. June Maker and colleagues as an intervention for gifted students to develop creative problem solving ability through the use of real-world problems. The primary purpose of this study was to examine the effects of the REAPS model on developing students' general creativity and creative problem solving in science with two durations as independent variables. The long duration of the REAPS model implementation lasted five academic quarters or approximately 10 months; the short duration lasted two quarters or approximately four months. The dependent variables were students' general creativity and creative problem solving in science. The second purpose of the study was to explore which aspects of creative problem solving (i.e., generating ideas, generating different types of ideas, generating original ideas, adding details to ideas, generating ideas with social impact, finding problems, generating and elaborating on solutions, and classifying elements) were most affected by the long duration of the intervention. The REAPS model in conjunction with Amabile's (1983; 1996) model of creative performance provided the theoretical framework for this study. The study was conducted using data from the Project of Differentiation for Diverse Learners in Regular Classrooms (i.e., the Australian Project) in which one public elementary school in the eastern region of Australia cooperated with the DISCOVER research team at the University of Arizona. All students in the school from first to sixth grade participated in the study. The total sample was 360 students, of which 115 were exposed to a long duration and 245 to a short duration of the REAPS model. The principal investigators used a quasi-experimental research design in which all students in the school received the treatment for different durations. Students in both groups completed pre- and posttests using the Test of Creative Thinking

    This image of Cambodia's Angkor region, taken by NASA's Airborne Synthetic Aperture Radar (AIRSAR), reveals a temple (upper-right) not depicted on early 19th Century French archeological survey maps and American topographic maps. The temple, known as 'Sman Teng,' was known to the local Khmer people, but had remained unknown to historians due to the remoteness of its location. The temple is thought to date to the 11th Century: the heyday of Angkor. It is an important indicator of the strategic and natural resource contributions of the area northwest of the capitol, to the urban center of Angkor. Sman Teng, the name designating one of the many types of rice enjoyed by the Khmer, was 'discovered' by a scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif., working in collaboration with an archaeological expert on the Angkor region. Analysis of this remote area was a true collaboration of archaeology and technology. Locating the temple of Sman Teng required the skills of scientists trained to spot the types of topographic anomalies that only radar can reveal.

    The rapid and widespread expansion of rubber plantations in Southeast Asia necessitates a greater understanding of tree physiology and the impacts of water consumption on local hydrology. Sap flow measurements were used to study the intra- and inter-annual variations in transpiration rate (Et) in a rubber stand in the low-elevation plain of central Cambodia. Mean stand sap flux density (JS) indicates that rubber trees actively transpire in the rainy season, but become inactive in the dry season. A sharp, brief drop in JS occurred simultaneously with leaf shedding in the middle of the dry season in January. Although the annual maxima of JS were approximately the same in the two study years, the maximum daily stand Et of ∼2.0 mm day(-1) in 2010 increased to ∼2.4 mm day(-1) in 2011. Canopy-level stomatal response was well explained by changes in solar radiation, vapor pressure deficit, soil moisture availability, leaf area, and stem diameter. Rubber trees had a relatively small potential to transpire at the beginning of the study period, compared with average diffuse-porous species. After 2 years of growth in stem diameter, transpiration potential was comparable to other species. The sensitivity of canopy conductance (gc) to atmospheric drought indicates isohydric behavior of rubber trees. Modeling also predicted a relatively small sensitivity of gc to the soil moisture deficit and a rapid decrease in gc under extreme drought conditions. However, annual observations suggest the possibility of a change in leaf characteristics with tree maturity and/or initiation of latex tapping. The estimated annual stand Et was 469 mm year(-1) in 2010, increasing to 658 mm year(-1) in 2011. Diagnostic analysis using the derived gc model showed that inter-annual change in stand Et in the rapidly growing young rubber stand was determined mainly by tree growth rate, not by differences in air and soil variables in the surrounding environment. Future research should focus on the

    This image shows the Old Khmer Road (Inrdratataka-Bakheng causeway) in Cambodia extending from the 9th Century A.D. capitol city of Hariharalaya in the lower right portion of the image to the later 10th Century AD capital of Yasodharapura. This was located in the vicinity of Phnom Bakheng (not shown in image). The Old Road is believed to be more than 1000 years old. Its precise role and destination within the 'new' city at Angkor is still being studied by archeologists. But wherever it ended, it not only offered an immense processional way for the King to move between old and new capitols, it also linked the two areas, widening the territorial base of the Khmer King. Finally, in the past and today, the Old Road managed the waters of the floodplain. It acted as a long barrage or dam for not only the natural streams of the area but also for the changes brought to the local hydrology by Khmer population growth.

    The image was acquired by NASA's Airborne Synthetic Aperture Radar (AIRSAR).

    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.

    NASA Technical Reports Server (NTRS)

    2002-01-01

    This image of Lovea, Cambodia, was acquired by NASA's Airborne Synthetic Aperture Radar (AIRSAR). Lovea, the roughly circular feature in the middle-right of the image, rises some 5 meters (16.4 feet) above the surrounding terrain. Lovea is larger than many of the other mound sites with a diameter of greater than 300 meters (984.3 feet). However, it is one of a number highlighted by the radar imagery. The present-day village of Lovea does not occupy all of the elevated area. However, at the center of the mound is an ancient spirit post honoring the legendary founder of the village. The mound is surrounded by earthworks and has vestiges of additional curvilinear features. Today, as in the past, these harnessed water during the rainy season, and conserved it during the long dry months of the year.

    The village of Lovea located on the mound was established in pre-Khmer times, probably before 500 A.D. In the lower left portion of the image is a large trapeng and square moat. These are good examples of construction during the historical 9th to 14th Century A.D. Khmer period; construction that honored and protected earlier circular villages. This suggests a cultural and technical continuity between prehistoric circular villages and the immense urban site of Angkor. This connection is one of the significant finds generated by NASA's radar imaging of Angkor. It shows that the city of Angkor was a particularly Khmer construction. The temple forms and water management structures of Angkor were the result of pre-existing Khmer beliefs and methods of water management.

    Hariharalaya, the ancient 9th Century A.D. capitol of the Khmer in Cambodia, is shown in the upper center portion of this NASA Airborne Synthetic Aperture Radar (AIRSAR) image. The image was acquired during the 1996 PACRIM mission with AIRSAR operating in the TOPSAR mode. At the center of the image is the terraced sandstone temple mountain of the King Indravarman, the Bakong. The smaller enclosed rectangular feature just to the north is Preah Ko. Further to the south are more rectangular features, temples and water reservoirs attributed to other kings in the earlier part of the 9th Century A.D. and maybe even earlier. Just visible at the top on the image is a long linear feature that forms the southern border of the immense water reservoir, at the center of which is the Lolei temple. The city was the first capitol of the Khmer after the 802 A.D. ceremony consecrating the king as 'Devaraja'. This usually translated as 'god who was king' or 'king who was god'. In the next century, the center of power shifted to the northwest, to the area known today as Angkor.

    Thus this early capital is unique both in being the first after the historical 'founding' of the Khmer Empire, and for being inhabited for a relatively short time. Although kings returned from Angkor in the 11th and 12th Centuries A.D. to build the temple known as the Lolei and to construct the tower in the center of Bakong, the city of Hariharalaya remained on the perimeter of royal power. It was revered, however, as part of a longstanding and important custom of ancestral veneration. This manifested itself in a complex set of rituals honoring one's forebears--also ensuring legitimacy for one's claim to the throne. So behind this seemingly simple patterning of rectangles on the radar image lies many layers of history, ritual and meaning for the Khmer people, past and present.

    This paper offers a new interpretation of the 'resistance' carried out by local civil society organisations in Cambodia against intimate partner violence (IPV). In this, the paper explores the nexus between 'rupture', 'resistance' and 'repetition' and concludes that different 'repetitions' can contribute to acts of violence while simultaneously creating possibilities for resisting IPV. In regard to the latter, the concept of 'rupture' is investigated as a performative politics through which organisations try to disrupt the 'repetitions' of violent masculinities. Furthermore, it is argued that the importance of 'repetitions' and the concept of time should be acknowledged. The French criminal defence lawyer Jacques Vergès' understanding of 'rupture' and the French philosopher Gilles Deleuze's notions of 'repetition' inform the analysis. To exemplify our discussion and findings, the paper embraces stories of a number of civil society workers who facilitate various men's groups in Cambodia in order to negotiate the practice of IPV.

    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. PMID:18160981

    HIV transmission in Cambodia has declined considerably in recent years, yet new incidents of HIV transmission within marital relationships have increased. Evidence suggests that the cause of this is transmission from HIV-positive men to their HIV-negative spouses. The objective of this paper is to develop an evidence-based model of HIV transmission from husbands to wives in Cambodia in a context of culture and society, drawing from the published literature. A critical analysis of peer reviewed literature, professional papers, policy reports and reference books identified four plausible factors influencing inter-spousal HIV transmission: (1) a hierarchical male-dominated society, (2) husbands' involvement with sex workers, (3) cultural values concerning the ideal Khmer woman and (4) unprotected sex between an HIV-infected husband and his uninfected wife. This evidence-based explanatory model can be used to inform future culturally appropriate HIV-education and prevention programmes. PMID:23701215

    The agents of human febrile illness can vary by region and country suggesting that diagnosis, treatment, and control programs need to be based on a methodical evaluation of area-specific etiologies. From December 2006 to December 2009, 9,997 individuals presenting with acute febrile illness at nine health care clinics in south-central Cambodia were enrolled in a study to elucidate the etiologies. Upon enrollment, respiratory specimens, whole blood, and serum were collected. Testing was performed for viral, bacterial, and parasitic pathogens. Etiologies were identified in 38.0% of patients. Influenza was the most frequent pathogen, followed by dengue, malaria, and bacterial pathogens isolated from blood culture. In addition, 3.5% of enrolled patients were infected with more than one pathogen. Our data provide the first systematic assessment of the etiologies of acute febrile illness in south-central Cambodia. Data from syndromic-based surveillance studies can help guide public health responses in developing nations. PMID:22302857

    A new methodology for measuring human security is presented. The three stages of the methodology are: i) threat assessment, ii) data collection and organization, and iii) data visualization and analysis, using Geographic Information Systems. Results from a Cambodia case study are highlighted. The United Nations Development Program's notion of human security, which gives equal weight to economic, health, food, political, personal, and environmental factors, is used. Country-specific threats in each category are determined, and local, spatially referenced data are collected. In this paper, poverty, dengue fever, and tuberculosis are used as examples of the analytic process. Regions of Cambodia exposed to all three of these threats ("hot spots") are located, and spatial correlation between poverty, dengue fever, and tuberculosis is calculated. The methodology i) advances a broad concept of human security, ii) will potentially assist policy and decision makers, and iii) identifies research questions that cannot be resolved using single-sector analysis.

The aim of this paper is to identify, analyse and recommend those management system factors that are critical to the success of health management performance, with a particular focus on provincial management. The review has identified critical success factors associated with health management performance at the sub-national level that include a stronger role for effective human resource management in health sector reform, elevation of the status of planning in senior level management, and the development of a more comprehensive and transparent finance system. These success factors will position the provincial level of health management to respond more effectively to the reform challenges of administrative de-concentration and political decentralization that are currently underway across a range of government sectors in Cambodia.

    The debate around the issues raised by HIV/AIDS and human rights has largely focused on the protection from rights violations of individuals or groups affected by the disease. The relationship between political and social conditions where human rights abuses are frequent and the spread of HIV infection has been less studied. Two countries in Southeast Asia, Burma and Cambodia, are currently undergoing serious and uncontrolled epidemics of HIV; both are marked by political cultures of state violence and corruption, chronic civil war and insurgency, and widespread human rights violations. This article attempts to investigate associations between rapid HIV spread and political and social crises, using Burma and Cambodia as case studies. The climate and context of rights abuses are seen as significant factors of national vulnerability to the epidemic spread of HIV/AIDS. PMID:10347369

    Background Psychological and social problems are major concerns in this era of successful antiretroviral therapy. Although livelihood programs have been implemented extensively to improve the daily living conditions of people living with HIV in Cambodia, no studies have yet investigated the impacts of these programs on the mental health of this vulnerable population. Therefore, we examined the impact of a livelihood program on depressive symptoms and associated factors among people living with HIV in Cambodia. Design A quasi-experimental, nonequivalent comparison group study was conducted in six provinces of Cambodia in 2014. Data were collected from an intervention group comprising 357 people living with HIV who had participated in the livelihood program and a comparison group comprising 328 people living with HIV who had not participated in this program. Multiple logistic regression analysis was carried out to examine the association between livelihood-program participation and depressive symptoms as measured by the depressive symptoms subscale of the 25-item Cambodian version of the Hopkins Symptom Checklist. A propensity score matching was used to examine the effect of the livelihood program on depressive symptoms while controlling for selection bias. Results Overall, 56.0% and 62.7% of the participants in the intervention and comparison groups, respectively, met the Hopkins Symptom Checklist threshold for depressive symptoms. The multiple logistic regression analysis showed that the participants in the intervention group had significantly lower odds of having depressive symptoms (adjusted odds ratio 0.68, 95% confidence interval 0.52–0.88). The analysis from propensity score matching indicated that the livelihood program helped mitigate depressive symptoms among the participants in the intervention group (T=−1.99). Conclusions The livelihood program appeared to help mitigate the burden of depressive symptoms among people living with HIV in Cambodia. Thus

    This first extensive retrospective study of the molecular epidemiology of dog rabies in Cambodia included 149 rabies virus (RABV) entire nucleoprotein sequences obtained from 1998-2011. The sequences were analyzed in conjunction with RABVs from other Asian countries. Phylogenetic reconstruction confirmed the South-East Asian phylogenetic clade comprising viruses from Cambodia, Vietnam, Thailand, Laos and Myanmar. The present study represents the first attempt to classify the phylogenetic lineages inside this clade, resulting in the confirmation that all the Cambodian viruses belonged to the South-East Asian (SEA) clade. Three distinct phylogenetic lineages in the region were established with the majority of viruses from Cambodia closely related to viruses from Thailand, Laos and Vietnam, forming the geographically widespread phylogenetic lineage SEA1. A South-East Asian lineage SEA2 comprised two viruses from Cambodia was identified, which shared a common ancestor with RABVs originating from Laos. Viruses from Myanmar formed separate phylogenetic lineages within the major SEA clade. Bayesian molecular clock analysis suggested that the time to most recent common ancestor (TMRCA) of all Cambodian RABVs dated to around 1950. The TMRCA of the Cambodian SEA1 lineage was around 1964 and that of the SEA2 lineage was around 1953. The results identified three phylogenetically distinct and geographically separated lineages inside the earlier identified major SEA clade, covering at least five countries in the region. A greater understanding of the molecular epidemiology of rabies in South-East Asia is an important step to monitor progress on the efforts to control canine rabies in the region. PMID:26705238

    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 (HDDSCambodia, 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. PMID:26693758

    Cambodia had suffered enormously due to war and internecine conflict during the latter half of the twentieth century, more so during the Vietnam War. Total collapse of education and health systems during the Pol Pot era continues to be a challenge for developing the necessary infrastructure and human resources to provide basic minimum mental health care which is compounded by the prevailing cultural belief and stigma over mental, neurological and substance abuse disorders (MNSDs). The mental health research and services in Cambodia had been predominantly 'trauma focused', a legacy of war, and there is a need to move toward epidemiologically sound public health oriented mental health policy and service development. Integrating mental health program with primary health care services with specifically stated minimum package of activities at primary level and complementary package of activities at secondary level is an opportunity to meet the needs and rights of persons with mental, neurological and substance abuse disorders (PWMNSDs) in Cambodia, provided there is mental health leadership, government commitment and political will.

    SUMMARY Setting Previously treated tuberculosis (TB) patients are a priority for drug susceptibility testing (DST) to identify cases with multidrug resistance (MDR). In Cambodia, a recent study found that only one-third of smear-positive previously treated patients had DST results. Objective To quantify the gaps in detecting MDR in previously treated TB patients in Cambodia, and describe health workers’ perspectives on barriers, facilitators and potential interventions. Design We analyzed case notifications in Cambodia (2004–2012) and conducted semi-structured interviews with key stakeholders Results The proportion of previously treated notifications varied significantly across provinces 2010–12, in the context of longer term trends of decreasing relapse and increasing “other” retreatment notifications. Correct classification of patients’ TB treatment history and ensuring specimens from previously-treated patients are collected and reach the laboratory could nearly double the number of detected MDR-TB cases. Identified barriers include patients’ reluctance to disclose and staff difficulty eliciting treatment history, partly due to availability of streptomycin only in hospitals. Facilitators include trained health workers, collection of sputum for DST even if previously treated patients are not taking streptomycin, streamlining sputum transportation and promptly reporting results. Conclusion Improved monitoring, supportive supervision, and correctly classifying previously treated patients are essential for improving detection of MDR-TB. PMID:25299861

    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.

  14. Knowledge, attitudes, and behavior. Cambodia's monks, nuns fill gap for AIDS patients.

    1997-12-01

    The UN has reported that Cambodia has one of Asia's most serious HIV epidemics, with 100,000-120,000 of the country's 10.5 million people infected with HIV and up to 1 million more people to be potentially infected over the next 10 years. Cambodia has the fastest growing HIV/AIDS epidemic in the region. The country's resources, however, are inadequate and health facilities have been unable to keep up with the rapid spread of HIV/AIDS. Poverty, lack of education, widespread prostitution, limited condom use, and a social breakdown after years of war have all contributed to the problem. 50% of adult men regularly have sex with prostitutes, but they see no need to practice safer sex if a woman looks healthy. Furthermore, little professional and family care is available for the infected and sick. While doctors are few and far between in Cambodia, almost every community has a religious institution and many religious leaders are wiling to help people with AIDS. People in the religious community such as Buddhist monks and the Sisters of Charity help people mainly through counseling, encouragement to keep on living, and accommodating those who have no place else to go.

    Cornerstone, or guiding documents, for nursing and healthcare support the profession of nursing throughout the world. This article describes the impact of the civil war and instability in Cambodia that led to poverty and destruction of the healthcare system and provides a brief overview of nursing in Cambodia today. Since the 1990s, the Cambodian healthcare system has been recovering from war. Nurses have been transitioning from task oriented roles to more sophisticated roles that incorporate the nursing process. In addition to significant changes in nursing education and other advances in the healthcare system during the last five years, the Ministry of Health (MoH) has strongly encouraged the development of cornerstone documents to guide nursing practice for patient care provided in Cambodia. Standards and competencies have been developed based on the American Nurses Association (ANA) template for Scope and Standards of Practice. Cornerstone documents for nursing that have been implemented by the MoH, many at the Angkor Hospital for Children, include evidence based protocols, the nursing process framework, the Code of Ethics for Nurses and development of the Scope of Practice and Standards of Care for Cambodian Nurses.

    2013-01-01

    Introduction Human influenza infection poses a serious public health threat in Cambodia, a country at risk for the emergence and spread of novel influenza viruses with pandemic potential. Prior pandemics demonstrated the adverse impact of influenza on poor communities in developing countries. Investigation of healthcare resource distribution can inform decisions regarding resource mobilization and investment for pandemic mitigation. Methods A health facility survey performed across Cambodia obtained data on availability of healthcare resources important for pandemic influenza response. Focusing on five key resources considered most necessary for treating severe influenza (inpatient beds, doctors, nurses, oseltamivir, and ventilators), resource distributions were analyzed at the Operational District (OD) and Province levels, refining data analysis from earlier studies. Resources were stratified by respondent type (hospital vs. District Health Office [DHO]). A summary index of distribution inequality was calculated using the Gini coefficient. Indices for local spatial autocorrelation were measured at the OD level using geographical information system (GIS) analysis. Finally, a potential link between socioeconomic status and resource distribution was explored by mapping resource densities against poverty rates. Results Gini coefficient calculation revealed variable inequality in distribution of the five key resources at the Province and OD levels. A greater percentage of the population resides in areas of relative under-supply (28.5%) than over-supply (21.3%). Areas with more resources per capita showed significant clustering in central Cambodia while areas with fewer resources clustered in the northern and western provinces. Hospital-based inpatient beds, doctors, and nurses were most heavily concentrated in areas of the country with the lowest poverty rates; however, beds and nurses in Non-Hospital Medical Facilities (NHMF) showed increasing concentrations at higher

    This project aims to increase the resilience of Cambodian communities to the health risks posed by climate change-related impacts on water-related diseases. There are a number of water-related diseases that are present in Cambodia and are likely to be susceptible to climate change. These include diarrheal diseases, typhoid fever, leptospirosis, melioidosis, viral hepatitis, and schistosomiasis. Certain subsectors of Cambodia's population may be more vulnerable than others with respect to climate change impacts on water and health, including agricultural workers and residents of flood-and drought-prone areas. The current level of understanding on the part of health professionals and other key stakeholders in Cambodia regarding the risks posed by climate change on water-sensitive diseases is relatively low. Strategies by which this understanding might be strengthened are suggested. PMID:25388662

    2011-01-01

    Background Reliable information on mobility patterns of migrants is a crucial part of the strategy to contain the spread of artemisinin-resistant malaria parasites in South-East Asia, and may also be helpful to efforts to address other public health problems for migrants and members of host communities. In order to limit the spread of malarial drug resistance, the malaria prevention and control programme will need to devise strategies to reach cross-border and mobile migrant populations. Methodology The Respondent-driven sampling (RDS) method was used to survey migrant workers from Cambodia and Myanmar, both registered and undocumented, in three Thai provinces on the Thailand-Cambodia border in close proximity to areas with documented artemisinin-resistant malaria parasites. 1,719 participants (828 Cambodian and 891 Myanmar migrants) were recruited. Subpopulations of migrant workers were analysed using the Thailand Ministry of Health classification based on length of residence in Thailand of greater than six months (long-term, or M1) or less than six months (short-term, or M2). Key information collected on the structured questionnaire included patterns of mobility and migration, demographic characteristics, treatment-seeking behaviours, and knowledge, perceptions, and practices about malaria. Results Workers from Cambodia came from provinces across Cambodia, and 22% of Cambodian M1 and 72% of Cambodian M2 migrants had been in Cambodia in the last three months. Less than 6% returned with a frequency of greater than once per month. Of migrants from Cambodia, 32% of M1 and 68% of M2 were planning to return, and named provinces across Cambodia as their likely next destinations. Most workers from Myanmar came from Mon state (86%), had never returned to Myanmar (85%), and only 4% stated plans to return. Conclusion Information on migratory patterns of migrants from Myanmar and Cambodia along the malaria endemic Thailand-Cambodian border within the artemisinin resistance

    Injury is a growing public health concern worldwide. Since severe injuries require urgent treatment, involving smooth, timely patient referral between facilities, strengthening of the referral system would reduce injury mortality. Smooth referral consists of identification of severe cases, organization of transportation, communication between facilities and prompt care at the receiving facility. This study examined these components of referral of injured patients in a representative sample of health centres (HCs) and referral hospitals (RHs) in Cambodia. We analysed data from a survey carried out in 80 HCs and 17 RHs by interview or mailed questionnaire from December 2006 to April 2007. Collected information on referral included the presence of referral guidelines for injured patients, distance of referral, commonly used transportation and its cost, communication with receiving facilities, and fast-tracking at receiving facilities. Formal referral systems were not functioning well in some areas (insufficient communication and underutilization of ambulances), and informal systems were frequently involved (patient transfer by taxi or referral by community volunteers, and treatment by traditional healers) but were not fully integrated into the referral network (traditional healers seldom referred patients to public facilities). The referral distance was long for most of the surveyed facilities and transportation costs were high when transferring from remote areas, even by ambulance. This study identified the weaknesses and strengths of the emergency referral system in Cambodia. Streamlining referral mechanisms will require organization of each component of the referral mechanism by strengthening the existing system and mobilizing local resources, which would allow Cambodia to develop an efficient system at reasonable cost, though it may differ from Western models. Guidelines including these components along with training and supervision, and expansion of the system to

    Background Hypertension is strongly associated with adverse cardiovascular outcomes and was the leading modifiable associated factor for global disease burden in 2010. Analysis of modifiable associated factors will be important to those concerned with mitigating the adverse effects of hypertension. We studied factors associated with hypertension in adults aged 25–64 years of age in Cambodia in order to help develop strategies for planned new initiatives for prevention and control of hypertension. Methods Using data from a nationwide survey in Cambodia assessing the prevalence of associated factors for non-communicable disease in 2010 (WHO STEPs survey), 5017 participants between the ages of 25 and 64 years were included in a secondary analysis of the prevalence and predictors of hypertension. Results The prevalence of prehypertension in this sample was approximately double that of overall hypertension (27.9% vs 15.3%). Male sex, increasing age and known cardiovascular associated factors, including higher Body Mass Index (BMI), dyslipidaemia, impaired fasting glycaemia, and abdominal obesity were all associated with an increased prevalence of hypertension. In multivariate models, increasing age was the strongest associated factor for hypertension (OR 8.79, 95% CI (5.43 to 14.2)), whereas, higher BMI was the primary associated factor associated with prehypertension (OR 3.27, 95% CI 2.21 to 4.82). Conclusions Modifiable cardiovascular-associated factors are strongly correlated with prehypertension and hypertension in Cambodia, and may be a focus of public health and primary care strategies to mitigate subsequent ischaemic heart disease and stroke. A national strategy aimed at increased screening and adherence to medical therapy is a necessary first step to reduce burden of disease and related morbidities. PMID:27326148

    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. PMID:26298061

  3. A cross-sectional investigation of the quality of selected medicines in Cambodia in 2010

    2014-01-01

    Background Access to good-quality medicines in many countries is largely hindered by the rampant circulation of spurious/falsely labeled/falsified/counterfeit (SFFC) and substandard medicines. In 2006, the Ministry of Health of Cambodia, in collaboration with Kanazawa University, Japan, initiated a project to combat SFFC medicines. Methods To assess the quality of medicines and prevalence of SFFC medicines among selected products, a cross-sectional survey was carried out in Cambodia. Cefixime, omeprazole, co-trimoxazole, clarithromycin, and sildenafil were selected as candidate medicines. These medicines were purchased from private community drug outlets in the capital, Phnom Penh, and Svay Rieng and Kandal provinces through a stratified random sampling scheme in July 2010. Results In total, 325 medicine samples were collected from 111 drug outlets. Non-licensed outlets were more commonly encountered in rural than in urban areas (p < 0.01). Of all the samples, 93.5% were registered and 80% were foreign products. Samples without registration numbers were found more frequently among foreign-manufactured products than in domestic ones (p < 0.01). According to pharmacopeial analytical results, 14.5%, 4.6%, and 24.6% of the samples were unacceptable in quantity, content uniformity, and dissolution test, respectively. All the ultimately unacceptable samples in the content uniformity tests were of foreign origin. Following authenticity investigations conducted with the respective manufacturers and medicine regulatory authorities, an unregistered product of cefixime collected from a pharmacy was confirmed as an SFFC medicine. However, the sample was acceptable in quantity, content uniformity, and dissolution test. Conclusions The results of this survey indicate that medicine counterfeiting is not limited to essential medicines in Cambodia: newer-generation medicines are also targeted. Concerted efforts by both domestic and foreign manufacturers, wholesalers

    In the past decade, malaria control has been successfully implemented in Cambodia, leading to a substantial decrease in reported cases. Wide-spread use of malaria rapid diagnostic tests (RDTs) has revealed a large burden of malaria-negative fever cases, for which no clinical management guidelines exist at peripheral level health facilities. As a first step towards developing such guidelines, a 3-year cross-sectional prospective observational study was designed to investigate the causes of acute malaria-negative febrile illness in Cambodia. From January 2008 to December 2010, 1193 febrile patients and 282 non-febrile individuals were recruited from three health centers in eastern and western Cambodia. Malaria RDTs and routine clinical examination were performed on site by health center staff. Venous samples and nasopharyngeal throat swabs were collected and analysed by molecular diagnostic tests. Blood cultures and blood smears were also taken from all febrile individuals. Molecular testing was applied for malaria parasites, Leptospira, Rickettsia, O. tsutsugamushi, Dengue- and Influenza virus. At least one pathogen was identified in 73.3% (874/1193) of febrile patient samples. Most frequent pathogens detected were P. vivax (33.4%), P. falciparum (26.5%), pathogenic Leptospira (9.4%), Influenza viruses (8.9%), Dengue viruses (6.3%), O. tsutsugamushi (3.9%), Rickettsia (0.2%), and P. knowlesi (0.1%). In the control group, a potential pathogen was identified in 40.4%, most commonly malaria parasites and Leptospira. Clinic-based diagnosis of malaria RDT-negative cases was poorly predictive for pathogen and appropriate treatment. Additional investigations are needed to understand their impact on clinical disease and epidemiology, and the possible role of therapies such as doxycycline, since many of these pathogens were seen in non-febrile subjects.

    There remains a very high rate of smoked and smokeless tobacco use in the Western Pacific Region. The most recent findings from national adult tobacco surveys indicate that very few daily users of tobacco intend to quit tobacco use. In Cambodia, a nation that is predominantly Buddhist, faith-based tobacco control programs have been implemented where, under the fifth precept of Buddhism that proscribes addictive behaviors, monks were encouraged to quit tobacco and temples have been declared smoke-free. In the present study, we included items on a large national tobacco survey to examine the relation between beliefs (faith-based, other) about tobacco, health, and addiction among adults (18 years and older). In a stratified, multistage cluster sample (n = 13,988) of all provinces of Cambodia, we found that (1) 88–93% believe that Buddhist monks should not use tobacco, buy tobacco, or be offered tobacco during a religious ceremony; (2) 86–93% believe that the Wat (temple) should be a smoke-free area; (3) 93–95% believe that tobacco is addictive in the same way as habits (opium, gambling, alcohol) listed under the fifth precept of Buddhism; and (4) those who do not use tobacco are significantly more likely to cite a Buddhist principle as part of their anti-tobacco beliefs. These data indicate that anti-tobacco sentiments are highly prevalent in the Buddhist belief system of Cambodian adults and are especially evident among non-users of tobacco. Our findings indicate that faith-based initiatives could be an effective part of anti-tobacco campaigns in Cambodia. PMID:21948146

    Phthalate esters are used in a wide variety of consumer products, and human exposure to this class of compounds is widespread. Nevertheless, studies on dietary exposure of human to phthalates are limited. In this study, to assess the daily intakes of phthalate esters and the possible adverse health impacts, different food samples were collected from three areas of Cambodia, one of the poorest countries in the world. The ∑phthalate ester concentrations in Kampong Cham, Kratie and Kandal provinces ranged from 0.05 to 2.34 (median 0.88) μgg(-1), 0.19-1.65 (median 0.86) μgg(-1) and 0.24-3.05 (median 0.59) μgg(-1) wet weight (ww), respectively. Di-2-Ethylhexyl phthalate (DEHP) and diisobutyl phthalate (DiBP) were the predominant compounds among all foodstuffs. The estimated daily intake (EDI) of phthalate esters for the general population in Kampong Cham, Kratie and Kandal was 34.3, 35.6 and 35.8μgkg(-1) bw d(-1), respectively. The dietary daily intake of DEHP, benzylbutyl phthalate (BBP) and di-n-butyl phthalate (DBP) in Kampong Cham, Kratie and Kandal were below the tolerable daily intakes (TDI) imposed by the European Food Safety Authority (EFSA) and reference doses (RfD) imposed by The United States Environmental Protection Agency (USEPA). Rice contributed the greatest quantity of DEHP to the daily intake in Cambodia so may deserve further exploration. To our knowledge, this is the first study to investigate the occurrence and the daily intakes of phthalate esters in Cambodia. PMID:27372065

    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. PMID:27051442

    Global flows of people, information and capital have created transnational spaces in Cambodia. Within those spaces exists the formation of complex and multilayered interpersonal relationships between people attempting to capitalize on the opportunities created by these flows. The purpose of this article is to describe these transnational relationships, namely between young women employed in the entertainment sectors in Phnom Penh, and their western male partners, while highlighting the racialized and gendered motivations of the global actors, the inevitable sociocultural conflicts/constraints/ misunderstandings that arise within the partnerships, and the resulting challenges and psychobehavioral consequences experienced by the mobile and differentiated individuals involved in these postcolonial relational formations.

    Background The threadworm, Strongyloides stercoralis, endemic in tropical and temperate climates, is a neglected tropical disease. Its diagnosis requires specific methods, and accurate information on its geographic distribution and global burden are lacking. We predicted prevalence, using Bayesian geostatistical modeling, and determined risk factors in northern Cambodia. Methods From February to June 2010, we performed a cross-sectional study among 2,396 participants from 60 villages in Preah Vihear Province, northern Cambodia. Two stool specimens per participant were examined using Koga agar plate culture and the Baermann method for detecting S. stercoralis infection. Environmental data was linked to parasitological and questionnaire data by location. Bayesian mixed logistic models were used to explore the spatial correlation of S. stercoralis infection risk. Bayesian Kriging was employed to predict risk at non-surveyed locations. Principal Findings Of the 2,396 participants, 44.7% were infected with S. stercoralis. Of 1,071 strongyloidiasis cases, 339 (31.6%) were among schoolchildren and 425 (39.7%) were found in individuals under 16 years. The incidence of S. stercoralis infection statistically increased with age. Infection among male participants was significantly higher than among females (OR: 1.7; 95% CI: 1.4–2.0; P<0.001). Participants who defecated in latrines were infected significantly less than those who did not (OR: 0.6; 95% CI: 0.4–0.8; P = 0.001). Strongyloidiasis cases would be reduced by 39% if all participants defecated in latrines. Incidence of S. stercoralis infections did not show a strong tendency toward spatial clustering in this province. The risk of infection significantly decreased with increasing rainfall and soil organic carbon content, and increased in areas with rice fields. Conclusions/Significance Prevalence of S. stercoralis in rural Cambodia is very high and school-aged children and adults over 45 years were the most at

    This paper assesses the impact of three main destabilizing factors on marital stability in Cambodia: the radical reformation of marriage under the Khmers Rouges (KR); the imbalanced gender ratio among marriageable adults resulting from gendered mortality during the KR regime; and, after decades of isolation from the West, a period of rapid social change. Although there is evidence of declining marital stability in the most recent period, marriages contracted under the KR appear as stable as adjacent marriage cohorts. These findings suggest that the conditions under which spouses were initially paired matter less for marital stability than does their contemporaneous environment. PMID:16579210

    Polymorphism in the ortholog gene of the Plasmodium falciparum K13 gene was investigated in Plasmodium vivax isolates collected in Cambodia. All of them were Sal-1 wild-type alleles except two (2/284, 0.7%), and P. vivax K12 polymorphism was reduced compared to that of the P. falciparum K13 gene. Both mutant allele isolates had the same nonsynonymous mutation at codon 552 (V552I) and were from Ratanak Kiri province. These preliminary data should encourage additional studies for associating artemisinin or chloroquine resistance and K12 polymorphism. PMID:25385109

    In a medical mission to Cambodia, our team of doctors, dentists, and nurses saw over 1000 patients during 4 days of clinics. The most common cardiovascular problems were hypertension (11%) and heart murmurs (3%). Obesity and a history of diabetes were very rare. Unlike the cardiac patients I typically see in my Atlanta office, the Cambodians were trim and muscular from their predominantly farming and, less often, construction jobs. They are a gentle, seemingly happy people, appreciative of whatever limited medical help we could offer. Tuberculosis was the most prevalent serious illness noted. PMID:24688208

    Despite the recognition that people with disability are among the poorest and most marginalized, breaking the disability-poverty cycle has proven challenging. Although UN agencies, most donors, and nongovernmental organizations have disability and development policies, many programs perpetuate disability-based discrimination. Little research examines why such programs fail to achieve sustained livelihood improvement for people with disability. Findings from this study that explored the experience of disability in Cambodia suggest that programs must explicitly address social and cultural norms and power relations. Recommendations for inclusive practice are presented. Listening to the voices of people with disability is the crucial first step. PMID:23879427

    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. PMID:22011103

    Although the arctiine fauna of Cambodia remains poorly known, considerable progress has been made over the last seven years (Bucsek, 2012; Cerny & Pinratana, 2009; Bae et al., 2012; Dubatolov, 2012, 2013; Dubatolov et al., 2012, 2013). The genus Danielithosia (Arctiinae) was established by Dubatolov and Kishida (2012), with the type species Tigrioides aureolata Daniel, 1954 from Fujian, Sichuan, and Zhejiang, China. To date, this genus comprises 11 species in the world, most of which are distributed in the Palaearctic and Oriental Regions (Dubatolov, 2013). The genus Danielithosia can be recognized by the following characters: sacculus with a characteristic broadening subapically; juxta long, with a long sclerotized bifurcated process apically (Dubatolov et al., 2012). In Cambodia, only one species, D. hoenei Dubatolov, 2013, has been reported (Dubatolov, 2013), and we here describe one new species from Cambodia. Terminology in this paper follows Dubatolov et al. (2012), and the specimens used in this study are deposited in the collection of Incheon National University (INU), on indefinite loan from Cambodia. PMID:26249460

    Background 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. Method 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. Results 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.

    2013-04-01

    In Cambodia, dengue virus (DENV) was first isolated in 1963 and has become endemic with peak epidemic during raining season. Since 2000, the Dengue National Control Program has reported from 10,000 to 40,000 cases per year with fatality rates ranging from 0.7 to 1.7. All four dengue serotypes are found circulating in Cambodia with alternative predominance of serotypes DENV-2 and DENV-3. The DENV-1 represents from 5% to 20% of all circulating viruses, depending upon the year. In this work, 79 clinical strains of DENV-1 were isolated between 2000 and 2009 and their genome fully sequenced. Four distinct lineages with different dynamics were identified. The main evolutionary drive was negative selective pressure but each lineage was characterized by the presence of specific mutations acquired through evolution. Coexistence, extinction and replacement of lineages occurred over the 10-year period. Lineages 1, 2 and 3 were all detected since 2000-2002 and disappeared in 2003, 2004-2005 and 2007, respectively. Lineages 1 and 2 displayed different dynamics. Lineage 1 was very diverse whereas lineage 2 was very homogeneous. Lineage 4 which derived from lineage 3 in 2003 remained the only one at the end of the sampling period in 2008-2009 owing to a selective sweep. The lineages dynamic of DENV-1 viruses and consequences for molecular epidemiology are discussed. PMID:21757030

    The declining efficacy of artemisinin derivatives against Plasmodium falciparum in western Cambodia is a major concern. The knowledge gap in the understanding of the mechanisms involved hampers designing monitoring tools. Here, we culture-adapted 20 isolates from Pailin and Ratanakiri (areas of artemisinin resistance and susceptibility in western and eastern Cambodia, respectively) and studied their in vitro response to dihydroartemisinin. No significant difference between the two sets of isolates was observed in the classical isotopic test. However, a 6-h pulse exposure to 700 nM dihydroartemisinin (ring-stage survival assay -RSA]) revealed a clear-cut geographic dichotomy. The survival rate of exposed ring-stage parasites (ring stages) was 17-fold higher in isolates from Pailin (median, 13.5%) than in those from Ratanakiri (median, 0.8%), while exposed mature stages were equally and highly susceptible (0.6% and 0.7%, respectively). Ring stages survived drug exposure by cell cycle arrest and resumed growth upon drug withdrawal. The reduced susceptibility to artemisinin in Pailin appears to be associated with an altered in vitro phenotype of ring stages from Pailin in the RSA. PMID:23208708

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

    PubMed

    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. PMID:12321720

  14. Fairness of utilizing health care facilities and out-of-pocket payment burden: evidence from Cambodia.

    2013-05-01

    Catastrophic spending on health care through out-of-pocket payment is a huge problem in most low- and middle-income countries all over the world. The collapse of health systems and poverty have resulted in the proliferation of the private health sector in Cambodia, but very few studies have examined the fairness in ease of utilization of these services based on mode of payment. This study examined the utilization of health services for sickness or injury and identified its relationship with people's ability to pay for treatment seeking at various instances. Based on cross-sectional data from the Cambodian 2007 Demographic and Health Survey, the economic index estimated through principal component analysis and Lorenz curve was used to quantify the degree of fairness and equality in utilization and payment burden among the respondents. A distinct level of fairness was found in health care utilization and out-of-pocket payments. Specifically, use of private health care facilities and over-the-counter remedies dominate, and out-of-pocket payments cut across all socioeconomic strata. As many countries in low- and middle-income regions, and most importantly those in transition such as Cambodia, are repositioning their health systems, efforts should be made towards maintaining equitable access through adoption of finance mechanisms that make utilization of health care services fair and equitable.

    Forest malaria remains a major problem in many parts of Southeast Asia and South America. In Cambodia, where a significant reduction of malaria morbidity and mortality has been observed in the last 20 years, the forest malaria situation was studied in Chumkiri District by analysing the available passive case detection data and conducting malariometric (n=1018) and questionnaire surveys (n=374) in four forest-fringe villages. There has been a decreasing trend of malaria incidence from 2001. Plasmodium falciparum was highly predominant and P. vivax was rare. The nearby-forest villages showed significantly higher parasite rates than the far-from-forest villages (9.0% vs. 1.2%, p<0.01). Malaria was highly restricted to the male adults but was nearly non-existent in other accompanying family members, including small children and females. Low income and working in forests were strongly associated with the malaria risk. Our results suggest that transmission has greatly reduced in forest-fringe villages, but remains active in forests, which is primarily maintained between the forest vector Anopheles dirus and ethnic minority inhabitants. Specific interventions directed to these previously neglected in-forest inhabitants to protect themselves and male adult villagers during their forest activities are necessary to achieve an ultimate goal of malaria elimination from Cambodia.

  16. 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.

    Investment in agricultural land in the developing world has rapidly increased in the past two decades. In Cambodia, there has been a surge in economic land concessions, in which long-term leases are provided to foreign and domestic investors for economic development. More than two million hectares have been leased so far, sparking debate over the consequences for local communities and the environment. Here we combined official records of concession locations with a high-resolution data set of changes in forest cover to quantify the contribution of land concessions to deforestation between 2000 and 2012. We used covariate matching to control for variables other than classification as a concession that may influence forest loss. Nearly half of the area where concessions were granted between 2000 and 2012 was forested in 2000; this area then represented 12.4% of forest land cover in Cambodia. Within concessions, the annual rate of forest loss was between 29% and 105% higher than in comparable land areas outside concessions. Most of the deforestation within concessions occurred after the contract date, and whether an investor was domestic or foreign had no effect on deforestation rates. We conclude that land acquisitions can act as powerful drivers of deforestation.

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

    2013-06-01

    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.

    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.

    Background The continuing contribution of dengue fever to the hospitalization and deaths in hospital of infants and small children in Cambodia is associated with delays in presentation for medical attention, diagnosis and appropriate care. It is important to identify the reasons that influence these delays, in order to develop appropriate interventions to redress the impact of dengue. Methods Data on health seeking were collected during an ethnographic study conducted in two villages in the eastern province of Kampong Cham, Cambodia in 2004. Interviews were conducted with mothers whose children had been infected with suspected dengue fever, or who had been sick for other reasons, in 2003 and 2004. Results Women selected a therapeutic option based on perceptions of the severity of the child's condition, confidence in the particular modality, service or practitioner, and affordability of the therapy. While they knew what type of health care was required, poverty in combination with limited availability and perceptions of the poor quality of care at village health centers and public referral hospitals deterred them from doing so. Women initially used home remedies, then sought advice from public and private providers, shifting from one sector to another in a pragmatic response to the child's illness. Conclusion The lack of availability of financial resources for poor people and their continuing lack of confidence in the care provided by government centres combine to delay help seeking and inappropriate treatment of children sick with dengue.

    We describe a new, medium-sized Leptolalax species from the Kon Tum Plateau of Vietnam and adjacent Cambodia. Leptolalax isos sp. nov. is distinguished from its congeners by a combination of an absence of distinct dark brown/black dorsolateral markings; toes with rudimentary webbing, wide lateral dermal fringes in males and weak or absent lateral dermal fringes in females; most males with wide lateral dermal fringes on Finger II, a body size of 23.7-27.9 mm in 38 adult males and 28.6-31.5 mm in 9 adult females, near immaculate white chest and belly; absence of white speckling on the dorsum; and a call consisting of 2-3 notes with a dominant frequency of 5.9-6.2 kHz (at 22.4-22.8º C). Uncorrected sequence divergences between L. isos sp. nov. and all homologous 16S rRNA sequences available are >10%. At present, the new species is known from montane evergreen forest between ~650-1100 m elevation in northeastern Cambodia and central Vietnam. Habitat within the range of the new species is threatened by deforestation and upstream hydroelectric dams. PMID:26624626

    Since bovine immunodeficiency virus (BIV), known as bovine lentivirus, has been detected in dairy and beef cattle in various countries around the world, a prevalence study of antibodies to BIV and bovine leukemia virus (BLV) was conducted in draught animals in five provinces in Cambodia, where protozoan parasite infections were suspected in some animals. To clarify the status of draught animals including Haryana, Brahman, mixed-breed, local breed cattle and muscle water buffaloes, a total of 544 cattle and 42 buffaloes were tested, and 26.3 and 16.7%, respectively, were found positive for anti-BIV p26 antibodies determined by Western blotting. There were 5.3% positive for anti-BLV antibodies detected by immunodiffusion test among the cattle, but no reactors among buffaloes and no dual infection for both BIV and BLV was determined in this study. Peripheral blood mononuclear cells from BIV-seropositive cattle were found to have BIV-provirus DNA, as detected by polymerase chain reaction and subsequent Southern blot hybridization. This is the first evidence for the presence of BIV and BLV infections in draught animals in tropical countries such as Cambodia. This wide distribution of BIV suggests its association with problems in animal health as reported worldwide, and that a primary BIV infection can predispose death of affected animals by other aggressive pathogens or stresses.

    OBJECTIVE: To examine the effects on immunization equity of the large-scale contracting of primary health-care services in rural areas of Cambodia. METHODS: Data were obtained pre-intervention and post-intervention from a large-scale quasi-experiment in contracting with nongovernmental organizations to provide primary health care in nine rural districts of Cambodia between 1999 and mid-2001. Coverage targets and equity targets for all primary health-care services, including immunization of children, were explicitly included in the contracts awarded in five of nine rural districts which together have a population of over 1.25 million people. The remaining four districts used the traditional government model for providing services and were given identical targets. FINDINGS: After the 2.5 years of the trial, bivariate and multivariate analyses of the results suggested that although there was a substantial increase in the proportion of children who were fully immunized in all districts, children in the poorest 50% of households in the districts served by contractors were more likely to be fully immunized than poor children living in similar circumstances in districts using the government's model, all other things being equal. CONCLUSION: The contracting approach described in this paper suggests a means of moving towards a more equitable distribution of immunization services in developing countries. PMID:15628203

    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 remote areas and the

    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

    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

    Introduction In the mid-1990s, Cambodia faced one of the fastest growing HIV epidemics in Asia. For its achievement in reversing this trend, and achieving universal access to HIV treatment, the country received a United Nations millennium development goal award in 2010. This article reviews Cambodia’s response to HIV over the past two decades and discusses its current efforts towards elimination of new HIV infections. Methods A literature review of published and unpublished documents, including programme data and presentations, was conducted. Results and discussion Cambodia classifies its response to one of the most serious HIV epidemics in Asia into three phases. In Phase I (1991–2000), when adult HIV prevalence peaked at 1.7% and incidence exceeded 20,000 cases, a nationwide HIV prevention programme targeted brothel-based sex work. Voluntary confidential counselling and testing and home-based care were introduced, and peer support groups of people living with HIV emerged. Phase II (2001–2011) observed a steady decline in adult prevalence to 0.8% and incidence to 1600 cases by 2011, and was characterized by: expanding antiretroviral treatment (coverage reaching more than 80%) and continuum of care; linking with tuberculosis and maternal and child health services; accelerated prevention among key populations, including entertainment establishment-based sex workers, men having sex with men, transgender persons, and people who inject drugs; engagement of health workers to deliver quality services; and strengthening health service delivery systems. The third phase (2012–2020) aims to attain zero new infections by 2020 through: sharpening responses to key populations at higher risk; maximizing access to community and facility-based testing and retention in prevention and care; and accelerating the transition from vertical approaches to linked/integrated approaches. Conclusions Cambodia has tailored its prevention strategy to its own epidemic, established

    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 drug of choice for

    The Japanese ALOS-2 satellite was launched on May 24th, 2014. It has the L-band SAR, PALSAR-2. Kim,Y. and van Zyl, J.J. proposed a kind of Radar Vegetation Index (RVI) as RVI = 8 * σ0hv / (σ0hh + σ0vv + 2* σ0hv) by L-band full-polarimetric radar data. Kim, Y. and Jackson, T.J., et al. applied the equation into rice and soybean by multi-frequency polarimetric scatterometer above 4.16 meters from the ground. Their report showed the L-band was the most promising wave length for estimating LAI and NDVI from RVI. The author tried to apply the analysis to the actual paddy field areas, both Inashiki region and Miyagi region in the eastern main island, "Honshu", areas of Japan by ALOS-2/PALSAR-2 full-polarimetry data in the summer season, the main crop growing time, of 2015. Judging from conventional methods, it will be possible to discriminate paddy rice growing fields from reaped fields or the other crops growing fields by the PALSAR-2 data. But the RVI value is vaguely related to such land use or biomass at the present preliminary experiment. The continuous research by the additional PALSAR-2 full-polarimetry data should be desired.

    The popular media have publicized the idea that social networking Web sites (e.g., Facebook) may enrich the interpersonal lives of people who struggle to make social connections. The opportunity that such sites provide for self-disclosure-a necessary component in the development of intimacy--could be especially beneficial for people with low self-esteem, who are normally hesitant to self-disclose and who have difficulty maintaining satisfying relationships. We suspected that posting on Facebook would reduce the perceived riskiness of self-disclosure, thus encouraging people with low self-esteem to express themselves more openly. In three studies, we examined whether such individuals see Facebook as a safe and appealing medium for self-disclosure, and whether their actual Facebook posts enabled them to reap social rewards. We found that although people with low self-esteem considered Facebook an appealing venue for self-disclosure, the low positivity and high negativity of their disclosures elicited undesirable responses from other people.

    In December 1998, 2,700 metric tons of industrial waste containing high levels of mercury and other metals and possibly other toxic compounds were shipped illegally from Taiwan to Sihanoukville, Cambodia. There the waste was unloaded and transferred to a nearby inland dumpsite. An estimated 2,000 Sihanoukville residents were exposed to the waste occupationally or environmentally, and at least six deaths and hundreds of injuries have been associated with the incident. The authors describe the human exposures and associated morbidity and mortality, recount the medical and public health response, and consider the issues complicating epidemiologic analysis of the incident. They also consider the major issues highlighted by the incident, including the trade in toxic waste between developed and less developed countries, the factors that shape emergency public health responses in resource-poor environments, and the importance of prevention and preparedness in containing emergencies in developing countries.

    Public providers have no financial incentive to respect their legal obligation to exempt the poor from user fees. Health Equity Funds (HEFs) aim to make exemptions effective by giving NGOs responsibility for assessing eligibility and compensating providers for lost revenue. We use the geographic spread of HEFs over time in Cambodia to identify their impact on out-of-pocket (OOP) payments. Among households with some OOP payment, HEFs reduce the amount paid by 35%, on average. The effect is larger for households that are poorer and mainly use public health care. Reimbursement of providers through a government operated scheme also reduces household OOP payments but the effect is not as well targeted on the poor. Both compensation models raise household non-medical consumption but have no impact on health-related debt. HEFs reduce the probability of primarily seeking care in the private sector. PMID:24189447

    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. PMID:25916602

    2011-01-01

    Fair-trade and organic products are often sold at price premiums justified by smaller production volumes that are associated with greater social and environmental responsibility. The consumption of these products confers on the consumer a greater sense of morality – and usually a claim to better taste. This paper tells the story of attempts to promote organic/fair-trade rice production by de facto organic Cambodian farmers for export to North American and European markets in order to assist poor farmers to trade their way out of poverty. It demonstrates that instead of promoting sustainable agriculture and fair trade between developed and developing markets, organic/fair-trade projects may impose First World consumer ideals and tastes that are out of step with the larger realities of agrarian transition in Cambodia and the wider region of developing Southeast Asia.

    The paper gives an account of the development and implementation of a stakeholder management framework at Ream National Park, Cambodia. Firstly, the concept of stakeholder is reviewed in management and in conservation literatures. Secondly, the context in which the stakeholder framework was implemented is described. Thirdly, a five-step methodological framework is suggested: (1) stakeholder analysis, (2) stakeholder mapping, (3) development of generic strategies and workplan, (4) presentation of the workplan to stakeholders, and (5) implementation of the workplan. This framework classifies stakeholders according to their level of influence on the project and their potential for the conservation of natural resources. In a situation characterized by conflicting claims on natural resources, park authorities were able to successfully develop specific strategies for the management of stakeholders. The conclusion discusses the implications of the Ream experience and the generalization of the framework to other protected areas. PMID:11437000

    The “hydraulic city” of Angkor, the capitol of the Khmer Empire in Cambodia, experienced decades-long drought interspersed with intense monsoons in the fourteenth and fifteenth centuries that, in combination with other factors, contributed to its eventual demise. The climatic evidence comes from a seven-and-a-half century robust hydroclimate reconstruction from tropical southern Vietnamese tree rings. The Angkor droughts were of a duration and severity that would have impacted the sprawling city’s water supply and agricultural productivity, while high-magnitude monsoon years damaged its water control infrastructure. Hydroclimate variability for this region is strongly and inversely correlated with tropical Pacific sea surface temperature, indicating that a warm Pacific and El Niño events induce drought at interannual and interdecadal time scales, and that low-frequency variations of tropical Pacific climate can exert significant influence over Southeast Asian climate and society.

    Background Artemisinin combination therapy (ACT) is now the recommended first-line treatment for falciparum malaria throughout the world. Initiatives to eliminate malaria are critically dependent on its efficacy. There is recent worrying evidence that artemisinin resistance has arisen on the Thai-Cambodian border. Urgent containment interventions are planned and about to be executed. Mathematical modeling approaches to intervention design are now integrated into the field of malaria epidemiology and control. The use of such an approach to investigate the likely effectiveness of different containment measures with the ultimate aim of eliminating artemisinin-resistant malaria is described. Methods A population dynamic mathematical modeling framework was developed to explore the relative effectiveness of a variety of containment interventions in eliminating artemisinin-resistant malaria in western Cambodia. Results The most effective intervention to eliminate artemisinin-resistant malaria was a switch of treatment from artemisinin monotherapy to ACT (mean time to elimination 3.42 years (95% CI 3.32–3.60 years). However, with this approach it is predicted that elimination of artemisinin-resistant malaria using ACT can be achieved only by elimination of all malaria. This is because the various forms of ACT are more effective against infections with artemisinin-sensitive parasites, leaving the more resistant infections as an increasing proportion of the dwindling parasite population. Conclusion Containment of artemisinin-resistant malaria can be achieved by elimination of malaria from western Cambodia using ACT. The "last man standing" is the most resistant and thus this strategy must be sustained until elimination is truly achieved. PMID:19228438

    Low cost and attractive equipment for use in experimental higher physics education has been desired by teachers, especially those in developing world. A system of novel experimental apparatus named Personal Desk Lab (PDL) was developed [1]. Each apparatus is miniaturized to one-fifth of the conventional one or less, and built on a steel plate; therefore, it is portable and can be used on a classroom desk. Each set is constructed by some parts divided according to their functions, and some of the parts are used in a number of experiments; which saves material, cost, and storage space. All parts are designed to be easy to make, maintain and repair. Almost all apparatus are battery driven [2]. After ICPE 2006, we have improved the system continuously; consequently, the experimental themes cover the field of mechanics, electromagnetism and optics. The number of these themes in use exceeds ten. The performance of PDL has been tested at Chiba University, Japan and Royal University of Phnom Penh (RUPP), Cambodia. In Chiba University, physics education with PDL is currently conducted individually to 80(max.) students in a classroom at the same time, and to more than 900 students per year. Experiment class using PDL in Cambodia started on October 2008 with 120 students of physics department, RUPP. They were divided into three classes, and conducted four experimental themes in pairs. The advantages confirmed from the practices at two universities are as follows: (1) the use of PDL arouses learner's interest, promotes their deep understanding extensively, and inspires to learn further; and (2) costs for introduction and running of PDL system are fairly small compared to the traditional one. Furthermore, the instruction for distant learners having PDL on each hand was conducted successfully through internet.

    Background The threadworm Strongyloides stercoralis, the most neglected helminth, affects an estimated 30-100 million people worldwide. Information on S. stercoralis infection is scarce in tropical and sub-tropical resource poor countries, including Cambodia. We determined S. stercoralis infection prevalence and risk factors for infection in the general population in Southern Cambodia. Methods A cross-sectional study was carried out between January and April 2011 among 2,861 participants living in 60 villages of Takeo province, using Koga-agar plate culture, the Baermann technique and the Kato-Katz technique on a single stool sample. Results Eight intestinal helminth species were diagnosed. Hookworm (31.4%) and S. stercoralis (21.0%) occurred most frequently. Prevalence of S. stercoralis infection increased with age. In all age groups a higher prevalence was found among males than among females (OR: 1.7; 95% CI: 1.4 – 2.0; P < 0.001). Participants who had a latrine at home were significantly less frequently infected with S. stercoralis than those who did not (OR: 0.7; 95% CI: 0.4 – 0.8; P = 0.003). Muscle pain (OR: 1.3; 95% CI: 1.0 – 1.6; P = 0.028) and urticaria (OR: 1.4; 95% CI: 1.1 – 1.8; P = 0.001) were significantly associated with S. stercoralis infection. Conclusions S. stercoralis is highly prevalent among the general Cambodian population and should no longer be neglected. Access to adequate diagnosis and treatment is urgently needed. PMID:24886763

    In countries with a lack of primary care systems, health workers are of crucial importance to improving the delivery of health and animal health services at community level. But somehow they are rarely evaluated and usually with a top-down approach. This is the case in Cambodia, where thousands of Village Animal Health Workers (VAHWs) have been trained by the government, and where no standardized evaluation tool is available to accurately assess the situation. Based on methodology developed by the French NGO Agronomes et Vétérinaires Sans Frontières (AVSF) in Madagascar for farmers' association evaluation, we developed our own participatory methods to collect information about the VAHW context and build a criteria grid for their evaluation. In this framework, several participatory approaches were used such as problem trees, semi-structured interviews, pair-wise ranking and focus groups. The grid was built with the help of relevant stakeholders involved in the animal health system in Cambodia in order to (i) identify VAHW functions; (ii) set up criteria and associated questionnaires, and (iii) score the grid with all the stakeholders. The tool was divided into five categories of evaluation criteria: sustainability, treatment, production, vaccination and disease reporting. Our approach looked at local indicators of success developed and used by VAHWs themselves, which should lead to better acceptability of evaluation. This method gave priority to dialog aiming to engage decision makers and other stakeholders in a mutual learning process and could be applied in other countries to develop trust between health workers and official service representatives as well as to foster corrective action after evaluation.

    Abstract Objective To identify the demographic characteristics of current tobacco users in Cambodia, particularly women, and to explore the reasons for current tobacco use in demographic subgroups of the Cambodian population. Methods We used a stratified three-stage cluster sample of 13 988 adults aged 18 years and older from all provinces in 2005–2006. Participants completed an interviewer-administered survey that contained items on all forms of tobacco use and on health and lifestyle variables. Multivariable regression analysis was performed to identify demographic predictors of tobacco use. Findings Cigarette smoking occurred among 48.0% of men and 3.6% of women. We estimated that 560 482 women (95% confidence interval, CI: 504 783 to 616 180) currently chewed tobacco (typically as a component of betel quid) and that the prevalence more than doubles with each decade of adulthood up to the point that about half of all older women chew tobacco. Both men and women cited the influence of older relatives as their primary reason for starting to use tobacco. About one out of five rural women who used chewing tobacco started their habit for relief from morning sickness. The highest prevalence of chewing tobacco among women was seen among midwives (67.9%) and traditional healers (47.2%). High rates (66.8%) of cigarette and pipe tobacco use occurred among ethnic minorities who represent hill tribes found throughout south-east Asia. Conclusion The tobacco epidemic in Cambodia extends far beyond cigarette smoking in men. Tobacco control that focuses only on cigarettes will not address the health burden from smokeless tobacco use in women that may be an integral part of cultural, familial, and traditional medicine practices.

Questions related to the composition of the betel quid, the physiological and oral effects as well as traditional and sociological aspects. Statistical tests showed that there were differences between dental and medical students, particularly relating to the knowledge about oral effects. While 81.1% of dental students knew that betel quid chewing causes oral cancer, only 31.0% of the medical students were adequately informed. Similarly, 51.4% of the dental students knew about the relation between betel quid chewing and submucous fibrosis compared to 8.6% of the medical students (P < 0.001). In contrast, only 18.9% of the dental students thought that betel quid chewing strengthens the gum, while 56.9% of the medical students believed that betel quid chewing would have this effect (P < 0.001). The answers also showed that students do not indulge in the betel quid habit. The decline of the betel quid chewing habit was also indicated by the fact that while 5.3% of students had parents chewing betel quid, in contrast 40% of students reported grandparents with this habit. There are deficiencies of knowledge about the most important effects of betel quid chewing, particularly in medical students. Since both medical and dental students will in their future professional life have an enormous impact on health and health education, it seems justified that the dental and medical curricula should focus on these traditional habits. Proper health education starting in the dental and medical school is warranted in Cambodia and probably also in other South and Southeast Asian countries where the betel quid chewing habit is prevalent so as ultimately to improve public knowledge on the oral and other effects of this habit.

    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.

    In Cambodia, both anaemia and vitamin A deficiency are serious health problems. Despite this, few comprehensive nutritional surveys have been completed to date. This study evaluates the adequacy of iron and vitamin A intakes, as well as women's nutritional knowledge in rural Kandal province. Twenty-four hour recalls, pile sort activities, socioeconomic surveys, focus groups, and market surveys were carried out with 67 women from 5 villages in rural Kandal Province. Ninety seven percent of women did not meet their daily-recommended intake of iron, while 70% did not meet their daily-recommended intake of vitamin A. Although many women consume vitamin A-rich and iron rich-foods daily, they do not consume large enough quantities of these foods. Results suggest that both the cost of foods as well as the extent of health knowledge is linked to nutritional practice. Most animal-source iron and vitamin A-rich foods are considered expensive; however, small fish, and several plant-source vitamin A-rich foods are inexpensive and easy to access. Despite health education, food restrictions lead some healthy foods to be considered to be harmful to women. Ultimately, this study demonstrates the importance of developing comprehensive nutritional interventions in Cambodia. Health programming must provide women with not only suggestions to include low-cost nutrient-rich foods, but also advise them about the quantities that are likely to have an impact on nutritional status. Programs should take a community-based, inter-sectoral approach that simultaneously combines culturally informed health education with initiatives that combat poverty and increase access to nutrient rich foods.

    ABSTRACT Health care-associated infection (HCAI) is the most frequent adverse event for hospitalized patients. Hand hygiene is a simple and effective solution to protect patients from HCAI. This study aimed to introduce hand hygiene to health care workers based on the World Health Organization guideline for reducing HCAI in Cambodia and to assess their behavioral patterns on hand hygiene. All health care workers at Kampong Cham provincial hospital had lectures and practice on hand hygiene in January 2012. The surveys for hand hygiene compliance (HHC) were performed after 6 months, 1 year and 2 years, respectively. The number of surgical site infections (SSI) was counted in 2011 and 2014. Our analysis used the data of 58 workers, who were observed at all three points, although 139 workers were observed during the study period. The average of HHC at 6 months, 1 year and 2 years were 62.37%, 85.76% and 80.36%, respectively. The improved group (HHC 2 years/1 year≧1) had 32 workers, whereas the worsened group (HHC 2 years/1 year<1) had 26. There was a significant difference in departments of the two groups (P=0.011) but not in sex, age or occupations. The improved group had more workers of General (31.2% vs. 19.2%), Surgical (25.0% vs. 11.5%) and Infection (21.9% vs. 11.5%) categories compared to the worsened group. The incidence of SSI was improved from 32.26% in 2011 to 0.97% in 2014. Our results suggest that the education and the survey on hand hygiene are effective for reducing HCAI in Cambodia.

    A survey was conducted to better understand the contribution of farm productivity to rural household income and identify differences in production systems, feeding practices and development constraints to smallholder beef cattle producers in the four agro-ecological zones (AEZs) of Cambodia. A semi-structured questionnaire was used to interview 360 households in the four AEZs: I, the Great Lake Floodplain; II, the Mekong Floodplain; III, the Coastal and IV, the Plateau/Mountainous. In addition, samples of common nutritional resources used for cattle feed were collected for nutrient composition analysis, plus cattle were scored for body condition. Rice farming and cattle production were the most common sources of income in all AEZs. The average cattle herd size was 3.7 (SD = 2.4), but the majority of households raised 1-3 animals. The most common cattle management system was grazing with supplementation, mainly with rice straw and 'cut-and-carry' natural grasses fed during the wet season in all AEZs. The body condition score of all cattle types was 3.2 (SD = 0.8), except for cows in lactation that were 1.8. Major constraints to cattle production in AEZs I, II and III were lack of quality feed resources, capital for cattle production and concerns on breed quality, whereas in AEZ IV, diseases were identified as the main constraint. This survey confirms the importance of cattle to smallholders in the four AEZs. Interventions including farmer education to improve husbandry skills, increase the utilisation of forages and crop residues and address disease issues are necessary to enhance cattle production and rural livelihoods in Cambodia.

    In the small number of trials for matters such as genocide and crimes against humanity that have taken place before the Extraordinary Chambers in the Courts of Cambodia, by 2014 three occasions had arisen in which the fitness of the accused persons to participate in their trials had become contentious. This is hardly surprising given that the key period of Khmer Rouge government occurred a very long while ago--between 1975 and 1979. The accused persons are all aged. In two instances, the Trial Chamber of the Courts of its own motion sought expert evaluations of the accused persons' fitness to stand trial and, promptly, upon receipt of such reports, determined them to be fit by reference to criteria utilised by the Appeal Chamber of the International Criminal Court for the Former Yugoslavia (the ICTY). In the other instance an accused person, leng Thirith, was found unfit to stand trial and a range of important issues was traversed as to the measures that can properly be taken to try to render a person fit for trial and how legitimate the imposition of detention for that purpose is, and then how legitimate encroachments on a person's civil liberties are to monitor them if there is only a remote possibility that their mental state might improve. It is likely that the balance adopted by the Supreme Court Chamber in the Courts of Cambodia in making significant efforts to render an accused person fit for trial and then in continuing to monitor their mental state when such efforts do not bear fruit, instead of simply releasing them back into the community, will stand as an important precedent for future occasions under international criminal law when issues of fitness to stand trial and how they should be handled arise.

    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. PMID:23517629

  10. The village/commune safety policy and HIV prevention efforts among key affected populations in Cambodia: finding a balance

    The Village/Commune Safety Policy was launched by the Ministry of Interior of the Kingdom of Cambodia in 2010 and, due to a priority focus on “cleaning the streets”, has created difficulties for HIV prevention programs attempting to implement programs that work with key affected populations including female sex workers and people who inject drugs. The implementation of the policy has forced HIV program implementers, the UN and various government counterparts to explore and develop collaborative ways of delivering HIV prevention services within this difficult environment. The following case study explores some of these efforts and highlights the promising development of a Police Community Partnership Initiative that it is hoped will find a meaningful balance between the Village/Commune Safety Policy and HIV prevention efforts with key affected populations in Cambodia.
