A new sterol, langcosterol A (1), together with two known sterols 2 and 3, were isolated from the marine sponge Xestospongia testudinaria collected in Vietnam. Their chemical structures were elucidated on the basis of extensive spectroscopic analyses and comparisons with published data. The new compound 1 and the known compound 3 exhibited moderate cytotoxic activities against three human cancer cell lines (A549, lung cancer; MCF7, breast cancer; HeLa, cervical cancer) and a human normal cell line (WI-38 fibroblast), with IC50 values ranging from 29...

Heavy metal contamination of crop lands surrounding mines in North Vietnam is a major environmental issue for both farmers and the population as a whole. Technology for the production of biochar at a village and household level has been successfully introduced into Vietnamese villages. This study was undertaken to determine if rice straw biochar produced in simple drum ovens could remediate contaminated land. Tests were also carried out to determine if biochar and apatite mixed together could be more effective than biochar alone...

Highly pathogenic avian influenza (HPAI) H5N1 virus has been circulating in Vietnam since 2003, whilst outbreaks of HPAI H5N6 virus are more recent, having only been reported since 2014. Although the spatial distribution of H5N1 outbreaks and risk factors for virus occurrence has been extensively studied, there have been no comparative studies for H5N6. Data collected through active surveillance of Vietnamese live bird markets (LBMs) between 2011 and 2015 were used to explore and compare the spatiotemporal distributions of H5N1- and H5N6-positive LBMs...

BACKGROUND: Effective vaccines against porcine reproductive and respiratory syndrome virus (PRRSV), especially against highly pathogenic (HP) PRRSV are still missing. The objective of this study was to evaluate the protective efficacy of an experimental live attenuated PRRSV 2 vaccine, composed of two strains, against heterologous challenge with a Vietnamese HP PRRSV 2 field strain. For this reason, 20 PRRSV negative piglets were divided into two groups. The pigs of group 1 were vaccinated with the experimental vaccine, group 2 remained unvaccinated...

BACKGROUND: Circulating microRNAs (miRNA) are biomarkers for several neoplastic diseases, including hepatocellular carcinoma (HCC). We performed a literature search, followed by experimental screening and validation in order to establish a miRNA panel in combination with the assessment of alpha-fetoprotein (AFP) levels and to evaluate its performance in HCC diagnostics. METHODS: Expression of miRNAs was quantified by quantitative PCR (qPCR) in 406 serum samples from 118 Vietnamese patients with hepatitis B (HBV)-related HCC, 69 patients with HBV-related liver cirrhosis (LC), 100 chronic hepatitis B (CHB) patients and 119 healthy controls (HC)...

Altruistic surrogacy among close relatives has been legal in Vietnam since the beginning of 2015. Following the revision of the Marriage and Family Law, there have been dozens of cases of surrogacy, and instances of successful pregnancy and childbirth have also been reported. Although surrogacy was completely prohibited in 2003, numerous local brokers offered commercial surrogacy services. Today, surrogacy is permitted under very limited conditions, and commercial surrogacy is prohibited. However, brokers continue to offer illegal commercial surrogacy services, and some even present its incidence may be increasing...

BACKGROUND: There is an increasing global movement of foreign female entertainment workers (FEWs), a hard-to-reach population vulnerable to HIV/STIs. This paper described the needs assessment phase before intervention implementation where the socio-organisation, sexual risk behaviours and access to health services of foreign FEWs in Singapore were explored. We also highlighted how qualitative inquiry, census enumeration technique and community-based engagement approaches were used to gain access and to develop a culturally appropriate STI prevention intervention...

Infectious disease transmission is frequently mediated by the environment, where people's movements through and interactions with the environment dictate risks of infection and/or illness. Capturing these interactions, and quantifying their importance, offers important insights into effective interventions. In this study, we capture high time-resolution activity data for twenty-five Vietnamese farmers during collection and land application of human excreta for agriculture. Although human excreta use improves productivity, the use increases risks of enteric infections for both farmers and end users...

The Vietnamese Mekong delta is subsiding due to a combination of natural and human-induced causes. Over the past several decades, large-scale anthropogenic land-use changes have taken place as a result of increased agricultural production, population growth and urbanization in the delta. Land-use changes can alter the hydrological system or increase loading of the delta surface, amplifying natural subsidence processes or creating new anthropogenic subsidence. The relationships between land use histories and current rates of land subsidence have so far not been studied in the Mekong delta...

Large areas of the Vietnamese Mekong Delta floodplains (VMDF) are protected by high dikes to facilitate three rice crops per year. While this has increased rice production, there is evidence that triple rice systems have negative long-term effects, both environmental and economic. Double rice cropping, or other alternatives, may be more advantageous. We analyzed the costs and benefits of intensive rice systems over time and compared these with alternatives farming systems, based on data collected via field surveys and interviews with farmers in two provinces in the VMDF...

The present study investigated what complaints are prominent in psychologically distressed Vietnamese in Vietnam beyond standard symptoms assessed by Western diagnostic instruments for anxiety and depression. To form the initial Vietnamese Symptom and Cultural Syndrome Addendum (VN SSA), we reviewed the literature, consulted experts, and conducted focus groups. The preliminary VN SSA was then used in a general survey (N = 1004) of five provinces in Vietnam. We found that the VN SSA items were highly and significantly correlated with a measure of anxious-depressive psychopathology (a composite measure of the General Anxiety Disorder-7; Posttraumatic Diagnostic Scale; and Patient Health Questionnaire-9)...

Background: Hepatocellular carcinoma (HCC) is characterized by disparate risk patterns by race/ethnicity. We examined HCC incidence patterns and temporal trends among detailed racial/ethnic populations, including disaggregated Asian-American subgroups. Methods: Using data from the population-based California Cancer Registry, we identified 41 929 invasive HCC cases diagnosed during 1988-2012. Patients were grouped into mutually exclusive racial/ethnic groups of non-Hispanic (NH) white, NH black, Hispanic, and NH Asian/Pacific Islander (API), as well as Asian subgroups of Chinese, Filipino, Japanese, Korean, Vietnamese, Cambodian, Laotian, and South Asian...

Men who have sex with men (MSM) in Vietnam experience disproportionate rates of HIV infection. To advance understanding of how structural barriers may shape their engagement with HIV prevention services, we draw on 32 in-depth interviews and four focus groups (n = 31) conducted with MSM in Hanoi between October 2015- March 2016. Three primary factors emerged: (1) Diversity, both in relation to identity and income; Vietnamese MSM described themselves as segregated into Bóng kín (hidden, often heterosexually-identified MSM) and Bóng lộ ('out,' transgender, or effeminate MSM)...

Screening for hepatitis B (HBV) among high-risk young adults can help prevent its transmission and lead to earlier treatment and better long-term health outcomes. Yet few interventions have focused on increasing HBV awareness among young adults. Social media (SM) may be an effective method for disseminating information and engaging young adults about HBV. In this pilot study, qualitative and quantitative methods were applied to collect information on current use and perceptions toward SM through semistructured interviews and focus groups with young Chinese and Vietnamese adults and community leaders from local organizations in Philadelphia...

INTRODUCTION: To date, death acceptance is not well investigated in the Vietnamese population. Cultural influences may affect death acceptance. The purpose of this phenomenological study is to describe Vietnamese cancer patients' lived experience with death acceptance. METHOD: Eleven Vietnamese patients with various cancer diagnoses participated in the study. Data were analyzed using the Giorgian method of data analysis. RESULTS: Themes of death acceptance found were (1) accepting destiny, (2) knowing and sacrificing the self, (3) believing in living persons and handing over responsibilities, (4) accepting death while continuing to fight for life, and (5) looking for a "role model death...
