RESUMO

BACKGROUND: Breast cancer incidence is increasing in Vietnam with studies indicating low levels of knowledge and awareness and late presentation. While there is a growing body of literature on challenges faced by women in accessing breast cancer services, and for delivering care, no studies have sought to analyse breast cancer messaging in the Vietnamese popular media. The aim of this study was to investigate and understand the content of messages concerning breast cancer in online Vietnamese newspapers in order to inform future health promotional content. METHODS: This study describes a mixed-methods media content analysis that counted and ranked frequencies for media content (article text, themes and images) related to breast cancer in six Vietnamese online news publications over a twelve month period. RESULTS: Media content (n = 129 articles & n = 237 images) sampled showed that although information is largely accurate, there is a marked lack of stories about Vietnamese women's personal experiences. Such stories could help bridge the gap between what information about breast cancer is presented in the Vietnamese media, and what women in Vietnam understand about breast cancer risk factors, symptoms, screening and treatment. CONCLUSIONS: Given findings from other studies indicating low levels of knowledge and women with breast cancer experiencing stigma and prejudice, more nuanced and in-depth narrative-focused messaging may be required.

RESUMO

In this study, we investigated the host choice of naïve Amphiprion ocellaris, a specialist, at two different stages of development (newly settling juveniles and post-settlement juveniles). The fish were exposed to their natural and unnatural host species in the laboratory and their fitness was assessed in terms of activity and growth rate. Newly settling juveniles exhibited little host preference, while post-settlement juveniles immediately associated with their most common host in the wild. The analysis of fish activity confirmed that A. ocellaris is diurnal; they are most active in the morning, less at midday and barely move at night. The average travelling distance of juveniles was shorter in the groups living with their natural host, increasing in the groups living with an unnatural host and was highest in groups that did not become associated with any other unnatural host species. Post-settlement juveniles living with the natural host species grew better than those living with unnatural hosts or without anemone contact. These results suggest that the welfare of A. ocellaris in captivity will be optimized by keeping them with their natural anemone host species, although more generalist Amphiprion species may survive in association with other hosts.

RESUMO

Antimicrobials are a core aspect of most livestock production systems, especially in low-and middle-income countries. They underpin the efficient use of scarce feed resources and stabilize returns on capital and labor inputs. Antimicrobial use (AMU) contributes to the production of healthy animals, yet AMU in livestock is linked to antimicrobial resistance (AMR) in animals, humans and the environment. The Vietnamese Platform for Antimicrobial Reduction in Chicken Production was implemented during 2016-2019 and was one of Southeast Asia's first interventions focused on AMU reductions in livestock production. The project targeted small-scale commercial poultry farms in the Mekong Delta region of Vietnam using a "randomized before-and-after controlled" study design. It provided farmers with a locally adapted support service (farmer training plan, advisory visits, biosecurity, and antimicrobial replacement products) to help them reduce their reliance on antimicrobials. A partial budget analysis was performed comparing the control group (status-quo) and intervention group (alternative). The median net farm-level benefit of the intervention strategies with the project's support was VND 6.78 million (interquartile range (IR) VND -71.9-89 million) per farm. Without project support the benefit was reduced to VND 5.1 million (IR VND -69.1-87.2 million) to VND 5.3 million (IR -VND 68.9-87.5 million) depending on the antimicrobial alternative product used. At the project level with a focus on AMU and its reduction, subsequently influence on the resistance reduction, our results showed that achieving resistance reduction benefits with the current knowledge and technologies required investment of at least VND 9.1 million (US$ 395.10) per farm during the project's lifetime. The results highlight the positive net profit for the majority of enrolled farms and a reasonable investments from the project. The recommendation focuses on the implementation of policies on financial support, legislation, and information as potential solutions to facilitate the application of intervention strategies to reduce AMU in poultry production.

RESUMO

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important swine pathogens because it is highly infectious and causes economic losses due to decreased pig productivity. In this study, the 603 bp complete major envelope protein encoding gene (ORF5) of 32 field PRRSV isolates from Vietnam collected during 2008-2012 were sequenced and analyzed. Multiple nucleotide (nt) and deduced amino acid (aa) alignments of ORF5 were performed on the 32 isolates: the representative strains (European and North American genotypes), Chinese strains available in GenBank and vaccine strains licensed for use in Vietnam. The results showed 94.8-100.0% nt identity and 94.0-100% aa similarity among the 32 isolates. These isolates shared similarities with the prototype of the North American PRRSV strain (VR-2332; nt 87.8-89.3%, aa 87.5-90.0%), and Lelystat virus, the prototype of the European PRRSV strain (LV; nt 61.1-61.9%, aa 55.1-57.0%). There was greater similarity with QN07 (nt 96.5-98.5%, aa 96.0-99.0%) from the 2007 PRRS outbreak in QuangNam Province, CH-1a (nt 93.2-95.1%, 91.5-93.5%) isolated in China in 1995 and JXA1 (nt 96.5-98.6%, aa 95.0-98.0%), the highly pathogenic strain from China isolated in 2006. The Vietnamese isolates were more similar to JXA1-R (nt 96.5-98.6%, aa 95.0-98.0%), the strain used in Chinese vaccines, than to Ingelvac MLV/BSL-PS (nt 87.2-89.0%, aa 86.0-89.0%). Phylogenetic analysis showed that the 32 isolates were of the North American genotype and classified into sub-lineage 8.7. This sub-lineage contains highly pathogenic Chinese PRRSV strains. This study documents genetic variation in circulating PRRSV strains and could assist more effective use of PRRS vaccines in Vietnam.

RESUMO

Background: Harlequin ichthyosis (HI) is a severe rare genetic disease that mainly affects the skin. Neonates with this disease are born with thick skin and large diamond-shaped plates covering most of their bodies. Affected neonates lose the ability to control dehydration and regulate temperature and are more susceptible to infections. They also face respiratory failure and feeding problems. These clinical symptoms are factors associated with high mortality rates of neonates with HI. Until now, there are still no effective treatments for HI patients and most patients die in the newborn period. Mutation in the ABCA12 gene, which encodes an adenosine triphosphate-binding cassette (ABC) transporter, has been demonstrated as the major cause of HI. Case presentation: In this study, we report the case who is one infant that was born prematurely at 32 gestational weeks with the whole body covered with thick plate-like scales of skin. The infant was severely infected with mild edema, multiple cracked skins full of the body, yellow discharge, and necrosis of fingers and toes. The infant was suspected to be affected by HI. Whole exome sequencing (WES) was performed as a tool for detecting the novel mutation in one prematurely born Vietnam infant with HI phenotype. And after that, the mutation was confirmed by the Sanger sequencing method in the patient and the members of his family. In this case, one novel mutation c.6353C > G (p.S2118X, Hom) in the ABCA12 gene, was detected in the patient. The mutation has not been reported in any HI patients previously. This mutation was also found in a heterozygous state in the members of the patient's family, including his parents, an older brother, and an older sister who are no symptoms. Conclusions: In this study, we identified a novel mutation in a Vietnamese patient with HI by whole exome sequencing. The results for the patient and the members of his family will be helpful in understanding the etiology of the disease, diagnosing carriers, assisting in genetic counseling, and emphasizing the need for DNA-based prenatal screening for families with a history of the disease.

RESUMO

BACKGROUND: Literature on the spirituality of cancer patients has been mainly focused on the experiences of western patients. Few studies explore the experience of Asian cancer patients, while no spiritual study on cancer patients has been conducted in Vietnam. PURPOSE: The purpose of this study was to survey the spiritual distress of cancer patients at two general hospitals in northern Vietnam. METHODS: This was a quantitative survey with a cross-sectional design. This study used purposive sampling with a fitting the inclusion criteria, alongside the Spiritual Distress Scale-Vietnam version (SDS-V). The data was collected by an investigator in two general hospitals in northern Vietnam. The study received approval from two research councils. RESULTS: The results demonstrated that the demographics of cancer patients in the study reflected the national data of Vietnam. Regarding the four exploratory dimensions, more than 50% of cancer patients expressed feeling hardship and sorrow, most did not feel loneliness, most patients reported a good relationship with others and God, while the majority of were afraid to discuss death. CONCLUSIONS: Due to impact of aging and poverty on the sample patients, further studies into the interconnectivity between economics and the spiritual health status of patients is recommended. Additionally, since the 132 Vietnamese cancer patients reported a positive relationship with others and God, healthcare professionals should study effective strategies to apply the above strengths in easing hardships for future cancer patients.

RESUMO

The usage of antimicrobials in livestock production is a driver for antimicrobial resistance worldwide. Reducing the use of antibiotics in the animal sector is a priority and requires a change in practices. Vietnam has diverse husbandry and antimicrobial use practices. The objective of this study was to determine the socio-economic and technical factors associated with antibiotic usage patterns on chicken farms in the north and south of Vietnam. Semi-structured interviews (n = 34) and on-farm questionnaires (n = 125) were conducted to collect socio-economic, technical, biosecurity, health management, and antibiotic usage data. Using Multivariate Corresponding Analysis, we identified three production systems (A, B, C) and three patterns of antibiotic usage (1, 2, 3). Group A raised indoor exotic chickens in an intensive setting and was associated with group 1, which used antibiotics according to company recommendations for both treatment and prevention. Group C raised free-range chickens for their own consumption and was associated with group 2, which used antibiotics according to drugstore advice for treatment. Finally, group B was a market-oriented, semi-confined system associated with group 3, which practiced experience-based antibiotic use and overuse. Farms in the south of Vietnam were associated with group 3 and those in the north with group 2. The prediction of antibiotic usage patterns based on farming practices could lead to the identification of a group of farms to be targeted in order to foster the more prudent use of antibiotics in Vietnam.

RESUMO

This study aims to establish the association of family support and nutrition and health education by health workers with the status of overweight and obesity among patients with type 2 diabetes mellitus (T2DM) receiving outpatient treatment at a hospital. This descriptive cross-sectional study was conducted on 280 outpatients with type 2 diabetes at Bach Mai hospital from December 2019 to September 2020 by using assessments of anthropometric parameters and examining dietary habits and family support, as well as nutrition and health education and counseling by health workers. The prevalence of overweight and obesity in patients with T2DM was 35.4% (51.2% in men and 22.2% in women; P < .05). Patients never or rarely supported by their families or counseled by health workers were more vulnerable to overweight and obesity than those who frequently received support and counseling (OR = 1.41 vs 2.06; P < .05). Family support and counseling from health workers play a crucial role in promoting and sustaining healthy dietary habits and proper physical exercise in diabetic patients, contributing to their lowered risk of overweight and obesity.

RESUMO

BACKGROUND: Adolescent knowledge of safe sex and sexually transmitted infections (STIs) can reduce the risk of STIs as well as unplanned pregnancies. OBJECTIVE: To describe the knowledge of safe sex and STIs and to identify related factors among high school students in Vientiane Prefecture, Lao PDR. METHOD: This was an analytical cross-sectional study conducted at one high school from January to February 2019. A self-administered questionnaire was used to collect information from respondents. The questionnaires were completed by 337 respondents who were selected by stratified random sampling. The data collected were entered into and analysed using EpiData and Stata 13.0 software. Descriptive and inferential statistics were applied to determine the factors associated with knowledge of safe sex and STIs. RESULTS: The results showed that nearly half of the participants (49.5%) had a good knowledge of safe sex and 51.9% of the respondents had a good knowledge of STIs. Significant positive associations were shown between knowledge of safe sex by students living with other people, those who had studied family planning and had religious beliefs reflecting acceptance to using birth control. Other factors positively associated with knowledge of STIs were students being in Grade 10, and who had studied STIs including HIV/AIDS. CONCLUSION: In this study, approximately half of the participants were aware of safe sex and had knowledge of STIs. There is a need to have comprehensive sexual education, particularly emphasising family planning, STIs, and HIV/AIDS for all grades in school.

RESUMO

OBJECTIVE: The study aims to explore the association between the adherence to dietary recommendations among type 2 diabetes mellitus (T2DM) patients with their fasting blood glucose levels. METHOD: This is a cross-sectional anthropometric and dietary study conducted on 169 T2DM patients receiving outpatient treatment at the Central Nursing and Rehabilitation Hospital in Thanh Hoa provincial hospital in Vietnam in 2018. RESULTS: The rate of patients who had good fasting glycemic control was still low (30.8%). Their diets were poor in energy and unbalanced; the contribution of carbohydrates to the total dietary intake was high (68.2%), and only 24.9% of patients consumed 4-6 meals/day. There was a statistically significant association between the dietary intake with carbohydrate dietary intake containing ≥60% carbohydrate and the number of meals per day (<4 meals) with their fasting blood glucose levels (OR = 4.964, p < 0.05 and OR = 16.508; p < 0.01, respectively). CONCLUSIONS AND RECOMMENDATIONS: Hospital staff are advised to combine treatment with dietary counseling to help patients controlling their weights and glycemic levels more efficient, thereby contributing to improving their treatment outcomes.

RESUMO

BACKGROUND: Overweight and obesity have short-term and long-term effects on children's physical and mental health. These conditions currently have a tendency to increase among Vietnamese school children. AIMS: This study aimed to assess the quality of life among 8-10 year-old children in Vietnam. METHODS: This cross-sectional study was conducted with a sample of 264 children aged 8-10 years (including 88 obese children and 176 normal-weight ones) at two primary schools in Hanoi, Vietnam, in 2018 and their mothers or fathers participated in this study. The Vietnamese version of the Pediatric Quality of Life Inventory (PedsQL) 4.0 generic score scales were used to collect information from children and their parents about the children's quality-of-life. Mean and standard deviation of PedsQL scores were calculated. Independent t-test was used to compare mean scores between normal-weight and obese children. RESULTS: Both child self reports and parent-proxy reports revealed that obese children had significantly lower scores for the total scales compared to normal weight children (80.7 versus 84.0; p < 0.05 for proxy reports and 77.6 vs 84.6; p < 0.001 for self reports). Total scale and subscale scores reported by parents were lower compared to those reported by children. Besides, 79% of normal weight children reported having PedsQL total scores in the highest quartile (≥75%), compared to 56.8 % of obese children (p = 0.01). Similarly, these proportions for parent-proxy reports were 79.5% and 65.9%, respectively (p < 0.05). Emotional scores were both found the lowest among the four subscales (71.6 for child self reports and 73.1 for parent-proxy reports). RECOMMENDATIONS: Interventions aimed to improve quality of life of overweight and obese children in Vietnam should not focus only on diet adjustment and physical exercise but need to address all dimensions of health-related quality of life, especially emotional, social and school functioning.

RESUMO

OBJECTIVE: This article aims to describe the knowledge, attitude, frequency and level of consumption regarding non-alcoholic carbonated soft drinks (NCSD) among students from two high schools in Hanoi. MATERIALS AND METHODS: A cross-sectional survey including a semi-quantitative food frequency were conducted with 620 students from two high schools, one in the urban area and the other in the rural area of Hanoi city. RESULTS: Data on knowledge of health risk associated with the consumption of NCSD showed neagtive results (only 11.9% of the students were able to identify all the contents of NCSD correctly, and 2.7% knew all eight health risks due to consumption of NCSD). Besides, 31.4% of all students did not have the intention to quit NCSD despite being aware of health risks associated with the consumption of NCSD. Students who reported consuming NCSD within one month prior to the study constituted 83.1%, and those who consumed NCSD 1-2 times/week accounted for the highest proportion, being 21.3%. On average, each student consumed 2,094 ml NCSD within one month prior to the study. Suburban students and male students consumed more than urban and female ones, respectively (p < 0.01). RECOMMENDATIONS: Students should be equipped with information about NCSD related health risks and encouraged to consume less NCSD.

RESUMO

As Vietnam confronts with the challenge of an aging population, the importance of quality of life for elderly people becomes apparent. This article aims to assess health-related quality of life (HRQoL) and its correlates for the elderly, using a cross-sectional study design. A total of 1599 adults, aged 60 years and older, were drawn from the 2016 baseline survey of Chi Linh Health and Demographic Surveillance System (CHILILAB HDSS), which incorporated the EQ-5D, to measure HRQoL. Data were analyzed using multivariate linear regression analyses. The EQ-5D index of the elderly was found to be 0.871 (95% confidence interval = 0.862-0.880). After controlling for covariates, there were statistically significant associations between lower HRQoL and older age (≥80 years), lower education, no pension, chronic disease(s), and health insurance schemes targeting poor/near poor/priority groups. Current and future policies for improving HRQoL in old age should be extended to cover the most vulnerable groups.

RESUMO

OBJECTIVE: To describe the cause-specific morbidity and mortality, and referral patterns of all neonates admitted to a tertiary referral hospital in the northern provinces of Vietnam. DESIGN: A prospective hospital based observational study. SETTING: The Neonatal Department, National Hospital of Pediatrics, Hanoi, Vietnam. PATIENTS: All admissions to the Neonatal Department over a 12 month period. MAIN OUTCOME MEASURES: Cause-specific morbidity and mortality; deaths. RESULTS: There were 5064 admissions with the commonest discharge diagnoses being infection (32%) and prematurity (29%). The case fatality ratio (CFR) was 13.9% (n = 703). Infection (38%), cardio/respiratory disorders (27%), congenital abnormalities (20%) and neurological conditions (10%) were the main causes of death. Of all the deaths, 38% had an admission weight ≥2500g. Higher CFR were associated with lower admission weights. Very few deaths (3%) occurred in the first 24 hours of life. Most referrals and deaths came from Hanoi and neighbouring provincial hospitals, with few from the most distant provinces. Two distant referral provinces had the highest CFR. CONCLUSIONS: The CFR was high and few deaths occurred in neonates <24 hours old. The high rates of infection call for an improvement in infection control practices and peripartum antibiotic use at provincial and tertiary level. Understanding provincial hospital capacity and referral pathways is crucial to improving the outcomes at tertiary centres. A quality of care audit tool would enable more targeted interventions and monitoring of health outcomes.

RESUMO

BACKGROUND: The evaluation of tools to accurately identify low birth weight (LBW) and/or premature newborns in resource-limited countries is a research priority. We explored the use of foot length, chest circumference, and mid-upper arm circumference (MUAC) measured within 24 h as diagnostic tools for identifying newborns who are LBW, premature, or both; and compared measurements taken at birth with those taken at five days of age. MATERIALS AND METHODS: An observational study was undertaken in Hoa Binh Province General Hospital, Vietnam, in ethnic minority newborns. Birth weight, foot length, chest circumference, and MUAC were measured within 24 h of birth and in a subset of 200, were repeated on day five of life. Gestational age was estimated using the New Ballard Score. Receiver Operating Characteristic curves and optimal cut-points (the point with the highest sensitivity and specificity where the sensitivity was at least 0.8) were calculated, for predicting prematurity, LBW, and both. Measurements within 24 h and at five days of life were compared. RESULTS: 485 newborns were recruited. Chest circumference and MUAC measured within 24 h of birth were found to be highly predictive of LBW (both yielding area under the curve [AUC] of 0.98, 95% confidence interval [CI] 0.96-0.99), and performed marginally better than foot length (AUC 0.94, 95%CI 0.92-0.96). The optimal cut-points for measurements within 24 h of birth were ≤ 7.4 cm for foot length; ≤ 30.4 cm for chest circumference; and ≤ 9.0 cm for MUAC. There was statistical evidence that anthropometric measurements taken within 24 h of birth were higher than measurements on day five (p<0.02 for all anthropometric measurements) but the magnitude of these differences was small (at most 2mm). CONCLUSIONS: All measurements taken within 24 h of birth were good predictors of LBW, prematurity and both. Differences in measurements taken within 24 h and on day five were not clinically relevant. Further research will ensure that the application of these measures is reliable in community settings.

RESUMO

A simple method was introduced to prepare magnetic chitosan nanoparticles by co-precipitation via epichlorohydrin cross-linking reaction. The average size of magnetic chitosan nanoparticles is estimated at ca. 30 nm. It was found that the adsorption of Cr(VI) was highly pH-dependent and its kinetics follows the pseudo-second-order model. Maximum adsorption capacity (at pH 3, room temperature) was calculated as 55.80 mg·g(-1), according to Langmuir isotherm model. The nanoparticles were thoroughly characterized before and after Cr(VI) adsorption. From this result, it can be suggested that magnetic chitosan nanoparticles could serve as a promising adsorbent for Cr(VI) in wastewater treatment technology.

RESUMO

BACKGROUND: Quality of life (QoL) is an important health index for the elderly, necessary for assessing interventions, and prioritising medical and social care needs. As the ageing population in Vietnam continues to increase, understanding important dimensions of QoL for the elderly is essential. There is a paucity of research in this area, however, and the available literature focuses on functional capacities. The purpose of this article is to explore perceptions on the dimensions of QoL among the elderly in Vietnam, to use these perceptions to broaden the concept, and to explore similarities and differences between those living in urban compared to rural areas. METHOD: Qualitative methods included in-depth interviews (IDI) with experts in ageing and elderly persons, as well as focus group discussions (FGDs) in three communes in Hai Duong province. IDIs and FGDs were recorded and transcribed. NVivo software was used to analyse the data. RESULTS: Thematic analysis identified physical, psychological, social, environmental, religious, and economic as important dimensions of QoL. For elderly participants in both urban and rural areas, physical health, social relations, finances and economics, the physical and social environment, and psychological health were reported as important. Rural participants also identified religious practice as an important dimension of QoL. In terms of relationships, the elderly in urban areas prioritised those with their children, while the elderly in rural areas focussed their concerns on community relationships and economic conditions. CONCLUSION: Isolating individual factors that contribute to QoL among the elderly is difficult given the inter-relations and rich cross-linkages between themes. Elderly participants in urban and rural areas broadly shared perspectives on the themes identified, in particular social relationships, but their experiences diverged around issues surrounding finances and economics, their respective physical and social environments, and the contribution of religious practice. The study findings may help provide guidance for the development of a socially and culturally relevant instrument for measuring QoL among the elderly in Vietnam. The results will also be useful for developing policies and interventions that are responsive to the needs of the elderly, and reflect the themes perceived to be important.

RESUMO

BACKGROUND: Vietnam is one of the most disaster-prone countries in the world. The country suffers from many kinds of natural disasters, of which the most common and serious one is flooding. Long and heavy rainfall during the last days of October and the first week of November 2008 resulted in a devastating flood unseen for over three decades in the capital city of Hanoi. It caused a substantial health impact on residents in and around the city and compromised the capacity of local health services. OBJECTIVE: The aim of this study is to ascertain the vulnerability and health impacts of the devastating flood in Hanoi by identifying the differences in mortality, injuries, and morbidity patterns (dengue, pink eye, dermatitis, psychological problems, and hypertension) between flood affected and non-affected households. DESIGN: A cross-sectional study was carried out involving 871 households in four selected communes (two heavily flood affected and two comparatively less affected) from two severely flooded districts of Hanoi. Participants were interviewed and information collected on the social, economic, and health impacts of the devastation within 1 month after the flood. RESULTS: The self-reported number of deaths and injuries reported in this study within 1 month after the heavy rainfall were a bit higher in severely affected communes as compared to that of the less affected communes of our study. The findings showed higher incidences of dengue fever, pink eye, dermatitis, and psychological problems in communes severely affected by flood as compared to that of the controlled communes. CONCLUSIONS: For people in flood prone areas (at risk for flooding), flood prevention and mitigation strategies need to be seriously thought through and acted upon, as these people are exposed to greater health problems such as psychological issues and communicable diseases such as pink eye or dermatitis.
