Child height is an important indicator of human capital and human development, in large part because early life health and net nutrition shape both child height and adult economic productivity and health. Between 2005 and 2010, the average height of children under 5 in Cambodia significantly increased. What contributed to this improvement? Recent evidence suggests that exposure to poor sanitation - and specifically to widespread open defecation - can pose a critical threat to child growth. We closely analyze the sanitation height gradient in Cambodia in these two years...

BACKGROUND: Traumatic brain injury (TBI) is a critical public health problem worldwide with a significant socioeconomic burden. While improved safety regulations in high-income countries have resulted in a decline in traffic-related TBI, the incidence of TBI in low-income countries is on the rise. We illustrate the trends and factors involved in TBI in a large Cambodian governmental hospital in Phnom Penh. Additionally, suggestions for improvement of the country's road traffic safety are discussed...

BACKGROUND: The recent dramatic decline in dihydroartemisinin-piperaquine (DHA-PPQ) efficacy in northwestern Cambodia has raised concerns about the rapid spread of piperaquine resistance just as DHA-PPQ is being introduced as first-line therapy in neighbouring countries. METHODS: Ex vivo parasite susceptibilities were tracked to determine the rate of progression of DHA, PPQ and mefloquine (MQ) resistance from sentinel sites on the Thai-Cambodian and Thai-Myanmar borders from 2010 to 2015...

BACKGROUND: The prevalence of HIV and sexually transmitted infections (STIs) among key populations in Cambodia continues to rise. To address this issue, KHANA, the largest national HIV organization in the country developed and implemented the Sustainable Action against HIV and AIDS in Communities (SAHACOM) project. This study aims to determine the impacts of the SAHACOM on sexual behaviors and the uptake of HIV/STI services among men who have sex with men (MSM) in Cambodia. METHODS: We compared outcome indicators at midterm (n = 352) and endline (n = 394)...

This study aimed to identify factors associated with cattle reproductive output in rural smallholder farms in Cambodia in order to determine the main causes of reproductive failure and design efficient interventions for improvement. The majority of the nation's beef is produced on smallholder farms where productivity is constrained by poor animal reproductivity reflected in the recent livestock population decline of approximately 13 % from 2009 to 2013. Farmers (n = 240) from 16 villages from five provinces were surveyed in mid-2015 to determine their baseline knowledge, attitude and practices (KAP) associated with cattle reproduction...

BACKGROUND: Malaria transmission is highly heterogeneous, especially in low endemic countries, such as Cambodia. This results in geographical clusters of residual transmission in the dry, low transmission season, which can fuel the transmission to wider areas or populations during the wet season. A better understanding of spatial clustering of malaria can lead to a more efficient, targeted strategy to reduce malaria transmission. This study aims to evaluate the potential of the use of serological markers to define spatial patterns in malaria exposure...

Opisthorchiasis caused by Opisthorchis viverrini is an important foodborne trematodiasis in Thailand, Laos and Cambodia. Interestingly, the opisthorchiasis endemic region overlaps with an area of leptospirosis emergence. Here we report an association between opisthorchiasis and leptospirosis in Thailand. Of 280 sera collected from villagers living around the Lawa wetland complex in Khon Kaen province, 199 (71%) were seropositive for leptospirosis by immunochromatography. Individuals with O. viverrini infection had a significantly higher rate of leptospirosis than those without (P=0...

PURPOSE: To determine whether trachoma is a public health problem requiring intervention in Cambodia. METHODS: Based on historical evidence and reports, 14 evaluation units (EUs) in Cambodia, judged to be most likely to harbor trachoma, were selected. The Global Trachoma Mapping Project methodology was used to carry out rigorous surveys to determine the prevalence of trachomatous inflammation-follicular (TF) and trichiasis in each EU. RESULTS: The EU-level prevalence of TF among 25,801 1-9-year-old children examined ranged from 0% to 0...

BACKGROUND: Access to cardiac surgery is limited in low-income settings, and data on patient outcomes are scarce. AIMS: To assess characteristics, surgical procedures and outcomes in patients undergoing open-heart surgery in low-income settings. METHODS: This was a cohort study (2001-2011) in two low-income countries, Cambodia and Mozambique, where cardiac surgery had been promoted by visiting non-governmental organizations. RESULTS: In Cambodia and Mozambique, respectively, 1332 and 767 consecutive patients were included; 547 (41...

The Cambodian National Strategic Plan for Elimination of Malaria aims to move step by step toward elimination of malaria across Cambodia with an initial focus on Plasmodium falciparum malaria before achieving elimination of all forms of malaria, including Plasmodium vivax in 2025. The emergence of artemisinin-resistant P. falciparum in western Cambodia over the last decade has drawn global attention to support the ultimate goal of P. falciparum elimination, whereas the control of P. vivax lags much behind, making the 2025 target gradually less achievable unless greater attention is given to P...

The recent Zika virus (ZIKV) outbreak has been linked to severe pathogenesis. Here, we report the construction of a plasmid carrying a cytomegalovirus (CMV) promoter-expressed prototype 1947 Uganda MR766 ZIKV cDNA that can initiate infection following direct plasmid DNA transfection of mammalian cells. Incorporation of a synthetic intron in the nonstructural protein 1 (NS1) region of the ZIKV polyprotein reduced viral cDNA-associated toxicity in bacteria. High levels of infectious virus were produced following transfection of the plasmid bearing the wild-type MR766 ZIKV genome, but not one with a disruption to the viral nonstructural protein 5 (NS5) polymerase active site...

Poor infant and young child feeding (IYCF) practices are major determinants of chronic malnutrition. The main objective of this study was to assess the impact of a nutrition education (NE) programme aimed at promoting improved IYCF behaviours in combination with an agriculture intervention on children's dietary diversity and nutritional status. From 2012 to 2014, a cluster randomised trial was rolled out in Cambodia in the context of an agriculture and nutrition project of the FAO of the UN. The cross-sectional baseline study was carried out in sixteen pre-selected communes in 2012...

In the current sense, Merogomphus Martin, 1904, is an artificial genus. It includes two unrelated groups of species: those with lyrate cerci with or without an outer spine and those with simple cerci, plus two species with large and broad epiproct branches placed in Merogomphus obviously in error. At the same time a number of species similar and obviously related to the former group were described from China in the genus Anisogomphus Selys, 1857. To resolve this taxonomic tangle, the genus Merogomphus is restricted to include only species with lyrate cerci: M pavici (Martin, 1904) (the type species), M...

BACKGROUND: Chronically dislocated hips (>6 weeks) are usually the consequence of difficulties accessing appropriate healthcare in a timely fashion after dislocation; this explains why they are more common in developing countries. Due to a lack of research, there is currently no consensus on the best treatment available for patients presenting with this condition. Therefore, it is important to assess the treatments available so as to ensure that doctors adequately manage those presenting with this debilitating condition in the future...

Non-marital births and divorce remain rare in Cambodia. Due to dramatic levels of adult mortality reached during the late 1970s, growing up with a single parent is not. Using nationally representative, cross-sectional data, we estimate that about 12% of children under age 18 co-reside with only one of their biological parents. Using longitudinal data representative of the Mekong River Valley, we find this proportion to be declining. Nearly half of these children live in nuclear families (single parent with or without a step-parent), even though they live in multigenerational families more frequently than children who live with both their parents, especially, when young and not living with their mother...

BACKGROUND: Dengue is endemic throughout Cambodia, a country faced with significant health and economic challenges. We undertook a clinical study at the National Paediatric Hospital in Phnom Penh to evaluate clinical diagnostic parameters for dengue and predictors of disease outcome. METHODS: Between September 2011 and January 2013, all consecutive inpatients aged between 1 and 15 years and presenting with suspected dengue were enrolled. They were clinically assessed using both the 1997 and 2009 WHO dengue classifications...

At the beginning of the new millennium, helminth infections continue to be prevalent, particularly among impoverished populations. This study attempts to create the first health informatics model of helminthiasis in Thailand. The authors investigate how a health informatics model could be used to predict the control and eradication in a national control campaign. Fish-borne helminthiasis caused by Opisthorchis viverrini remains a major public health problem in many parts of South-East Asia, including Thailand, Lao PDR, Vietnam and Cambodia...

Stellantchasmus falcatus (Digenea: Heterophyidae) is first reported from Cambodia through recovery of the metacercariae from mullet fish and adult flukes from an experimentally infected hamster. We purchased 7 mullets, Chelon macrolepis, in a local market of Phnom Penh, Cambodia, and each of them was examined by the artificial digestion method on May 2010. The metacercariae of S. falcatus were detected in all mullets (100%) examined, and their average density was 177 per fish. They were elliptical, 220×168 μm in average size...
