Prevalence, determinants, intervention strategies and current gaps in addressing childhood malnutrition in Vietnam: a systematic review.

BACKGROUND: Childhood malnutrition in all forms is a major public health issue worldwide. This review systematically examined the prevalence and determinants and identify the potential interventions and current gap in addressing malnutrition including undernutrition, overnutrition and micronutrient deficiencies (MNDs) in Vietnamese children aged 0-18 years old. METHODS: Embase, Scopus, PubMed, and Web of Science were systematically searched through June 2022 to identify relevant articles published within the past 25 years. Study selection and data extraction were performed by one reviewer and checked for accuracy by the other two reviewers in accordance with PRISMA guideline. Risk of publication bias was assessed using American Dietetic Association Quality Criteria Checklist. RESULTS: Seventy-two studies that met the inclusion criteria were included. Undernutrition has decreased over time but still 22.4%, 5.2% and 12.2% of children under 5 were stunted, wasted and underweight, respectively. Anaemia, iron, zinc, and vitamin D deficiencies were the more common forms of MNDs, the prevalence varied by age, region, and socioeconomic group. Population-based surveys reported that 11% and 48% of children aged 0-11 years old were iron and vitamin D deficient, respectively. Zinc deficiency affected almost one-quarter of the children and adolescents. Retinol deficiency was of less concern (< 20%). However, more evidence on MNDs prevalence is needed. Overweight and obesity is now on the rise, affecting one-third of school-aged children. The key determinants of undernutrition included living in rural areas, children with low birth weight, and poor socio-economic status, whereas living in urban and affluent areas, having an inactive lifestyle and being a boy were associated with increased risk of overweight and obesity. Nutrition specific intervention studies including supplementation and food fortification consistently showed improvements in anthropometric indices and micronutrient biomarkers. National nutrition-sensitive programmes also provided nutritional benefits for children's growth and eating behaviours, but there is a lack of data on childhood obesity. CONCLUSION: This finding highlights the need for effective double duty actions to simultaneously address different forms of childhood malnutrition in Vietnam. However, evidence on the potential intervention strategies, especially on MNDs and overnutrition are still limited to inform policy decision, thus future research is warranted.

Prevalence and risk factors of work-related musculoskeletal disorders among physical therapists in Ho Chi Minh City, Vietnam.

BACKGROUND: Understanding risk factors linked to work-related musculoskeletal disorders (WMSDs) is crucial for enhancing health promotion and ensuring workplace safety among healthcare professionals particularly physical therapists (PTs). However, in Vietnam, there has been lack of an investigation. Therefore, this study was to determine whether potential risk factors contributed to the occurrence of WMSDs among PTs in Ho Chi Minh City. METHOD: An online self-reported questionnaire for WMSDs comprising the Nordic Musculoskeletal Questionnaire (NMQ), Job-risk and Environmental factors, the Perceived Stress Scale (PSS-4) and the coping strategies, were distributed to PTs. They were enrolled if they had: age ≥ 22 years, graduated from PT program, a full-time job with ≥1 year of experience. Unadjusted and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were determined using Logistic regression. RESULTS: Our study found that within the past 12 months, the prevalence of WMSDs was 76.4% (n = 204/267): neck 58.4% and lower back 57.3%. PTs aged 22-29 years, < 4 years of education, and < 7 years of working experience were more likely to have WMSDs 2-3 times than those who did not. After adjusting for age, education, and work experience, PTs who engaged in manual techniques/exercises, lifting/transferring patients, and maintaining awkward postures were 5-7 times more likely to have WMSDs in the neck and lower back than those who did not. Environmental and psychological factors, such as number of treatment tables, size of electrotherapy rooms, using PTs modalities, and stress were significantly associated with WMSDs. More than 50% of PTs used modified positions and new treatment/techniques that did not aggravate their symptoms, as coping strategies. CONCLUSIONS: This study indicates potential risk factors associated with WMSDs, affecting the neck and lower back among PTs in Vietnam. These risk factors should be addressed to improve overall PTs health, retain skilled workers, and encourage them to continue working.

Post-COVID condition: a survey of patients recovered from COVID-19 in Central Vietnam.

INTRODUCTION: Evidence on post-COVID-19 conditions is emerging. This study aims to assess post-COVID conditions and related factors in COVID-19 patients in Central Vietnam. METHODOLOGY: A descriptive cross-sectional study was performed on people who have recovered from COVID-19 at least 2 weeks prior to the online survey. Participants were interviewed face-to-face after 6 and 9 months from the first survey. RESULTS: 53 patients (21.2%) were confirmed to have persistent symptoms, of which, 100% and 94.3% reported prolonged fatigue and full-body weakness respectively. Loss of appetite was reported by 90.6%, while persistent cough, insomnia, and trouble sleeping were reported by 86.3% of patients. Headaches and dyspnea were reported by 69.5% and 56.8% respectively, while other symptoms had lower rates. The prevalence of post-COVID condition showed a statistically significant relationship with the time of infection, duration of illness, treatment place, use of herbal medicine, adherence to the 5K message from Vietnam's Ministry of Health, and daily saltwater mouthwash (p < 0.05). However, the use of medicine and supplements was not related to the post-COVID condition (p > 0.05). After 6 months, 125 participants were interviewed face-to-face, and only 15 people (12.0%) reported having post-COVID symptoms, mainly prolonged fatigue (33.3%) and persistent cough (26.7%). After 9 months, these 15 patients no longer had symptoms related to the post- COVID-19 condition. CONCLUSIONS: The post-COVID condition can persist for several weeks or months, but will mostly be in remission after 6 months, and completely resolve after 9 months from the onset of the infection.

Sleep disorders among patients suffering from road traffic injuries in an urban setting of Vietnam: an exploratory study.

Sleep quality is an important indicator of treatment outcome for patients with traffic accident injuries. In Vietnam, the impacts of injury on sleep status are usually amplified in urban areas due to disproportionate distribution of mental care services between the city and less developed settings. Our study investigated deterioration in sleep quality and identified associated demographic factors among traffic injury patients in an small urban setting of Vietnam. A cross-sectional study was conducted among 408 patients in one provincial hospital and five district hospitals in Thai Binh, Vietnam from October to December 2018. A structured questionnaire was designed based on 3 standardized scales: Health-related Quality of Life, the Pittsburgh Sleep Quality Index and the Kessler Scale. Face-to-face interviews and medical records were conducted by trained health professionals on patients hospitalized in the Trauma-Orthopedic/Burn Department and Surgery and General Department. About 16.9% of respondents had sleep disturbances, and there was a statistically significant difference between age group (p < 0.01), education level (p < 0.01), and monthly household income (p < 0.01) between participants who with and without sleep disturbances. Furthermore, more than half (50.7%) of respondents sleep less than 5 h per day, while 18.7% of the sampled also reported that the habitual sleep efficiency was below 85%. Current results indicated that people being female, suffering from traumatic brain injury, being comatose at hospitalization, and having higher psychological distress scores were more likely to suffer from sleep problems. Our study is one of the first evidence in Vietnam to assess sleep disturbances in road traffic injury patients and their correlated factors. It is important to identify patients who are at risk of sleep disturbances based on socio-demographic and clinical characteristics, as well as psychological distress status. Therefore, a holistic approach should be taken to include sleep quality and psychological state in the treatment process and outcome assessment for road traffic injury patients.

A qualitative study on stress, coping strategies and feasibility of music intervention among women with cancer receiving chemotherapy during COVID-19 pandemic in Vietnam.

Breast and gynaecological cancer (BGC) patients receiving chemotherapy may experience high levels of stress during the COVID-19 pandemic. Music interventions may be effective in lowering their stress levels. This study explored stressors, coping strategies, and the feasibility of music interventions among BGC patients in Vietnam. An exploratory qualitative study with individual face-to-face semi-structured interviews was conducted. A convenience sample of BGC patients receiving chemotherapy was recruited from the oncology centre of a public hospital in Vietnam. Twenty patients were interviewed with open-ended questions developed based on the transactional model of stress and coping to explore stress-causing factors and coping strategies and based on guidelines for music therapy practice to explore their music preferences and perceptions. Field notes and interview transcripts were analysed following the qualitative content analysis approach. Two stressor themes were identified: undesirable experiences during treatment and patients' inability to fulfil their own roles and responsibilities. Our findings revealed a new coping strategy-self-realisation of responsibilities towards the family-that is not listed in the transactional model of stress and coping. Future psychological interventions for stress management among BGC patients should focus on raising the patients' awareness of their values and responsibilities towards their families. Three categories of preferred music genres for stress reduction were identified: religious, softly melodic, and revolutionary music. The patients were aware of the positive effects of music and had different musical preferences. This study also explored the acceptance of music interventions and facilitators and barriers to implementing them among BGC patients in Vietnam. The findings suggest that before implementing music interventions, the musical preferences, religions, and beliefs of each individual should be considered to achieve desirable results. Music interventions for BGC patients receiving chemotherapy in Vietnam are feasible. Further intervention studies are needed to evaluate their effectiveness.

Very preterm infants admitted to a tertiary neonatal unit in central Vietnam showed poor postnatal growth.

AIM: We aimed to evaluate the postnatal growth of very preterm infants. METHODS: This was a cross-sectional observational study of neonates born before 32 weeks of gestation and admitted to the neonatal unit at Da Nang Hospital for Women and Children, Vietnam, between 1 February 2020 and 30 September 2020. Morbidities, therapies, nutrition modalities and growth status were recorded from admission to discharge. RESULTS: The 78 infants (51% female) were born at a median of 29 weeks and mean birth weight of 1247 grams. The mean weight gain velocity from regaining their birth weight until discharge was 12.7 ± 4.9 g/kg/d. At discharge, the Z-scores for weight, length, both weight and length and weight for length were lower than at birth in 94%, 67%, 64% and 95% of infants and the Delta Z-scores were less than -1 in 73%, 44%, 39% and 82%. Late-onset sepsis (LOS) and bronchopulmonary dysplasia (BPD) were significantly associated with growth failure, with adjusted odds ratios of 3.6 and 20.1, respectively. CONCLUSION: The high rate of poor growth among the very preterm infants in our study indicates the need to reduce LOS and BPD and ensure the availability of human milk fortifier, vitamin and mineral supplements.

Perspectives on COVID-19 prevention and treatment using herbal medicine in Vietnam: A cross-sectional study.

Introduction: The significance of herbal medicine (HM) during the COVID-19 pandemic has been confirmed. Nevertheless, limited studies have included the people perspectives on COVID-19 prevention/treatment using herbal medicine in Vietnam. Thus, this study tackled the aforementioned issue. Methods: Online-based cross-sectional study was conducted in Vietnamese adults between February-April 2021. Descriptive analysis, regression and Chi-squared tests were implemented for the statistical purposes. Results: total of 787 respondents attended the study, 368 (46.8%) confirmed that they use herbal medicine/nutritional supplements for COVID-19 prevention/treatment. Over 50% of the respondents possessed positive perspective on vitamin C ingestion. Using herbal medicine for external use as a disinfectant was mostly preferred. Respondents who had a 'very good' health self-perception or who lived in rural areas, were more likely to have a positive opinion in the COVID-19 prevention/treatment using herbal medicine. The main barrier for herbal medicine utilization was the deficiency of personal experience or expert advice. Conclusion: The Vietnamese people commonly utilize herbal medicine for the COVID-19 prevention/treatment. These data might help policy-makers in managing the public knowledge and practice on herbal medicine use in Vietnam.

Understanding Malaria Persistence: A Mixed-Methods Study on the Effectiveness of Malaria Elimination Strategies in South-Central Vietnam.

Despite the scale-up of vector control, diagnosis and treatment, and health information campaigns, malaria persists in the forested areas of South-Central Vietnam, home to ethnic minority populations. A mixed-methods study using an exploratory sequential design was conducted in 10 Ra-glai villages in Bac Ai district of Ninh Thuan province to examine which social factors limited the effectiveness of the national malaria elimination strategy in the local setting. Territorial arrangements and mobility were found to directly limit the effectiveness of indoor residual spraying and long-lasting insectidical treated nets (LLINs). Households (n=410) were resettled in the "new villages" by the government, where they received brick houses (87.1%) and sufficient LLINs (97.3%). However, 97.6% of households went back to their "old villages" to continue slash-and-burn agriculture. In the old village, 48.5% of households lived in open-structured plot huts and only 5.7% of them had sufficient LLIN coverage. Household representatives believed malaria could be cured with antimalarials (57.8%), but also perceived non-malarial medicines, rituals, and vitamin supplements to be effective against malaria. Household members (n = 1,957) used public health services for their most recent illness (62.9%), but also reported to buy low-cost medicines from the private sector to treat fevers and discomfort as these were perceived to be the most cost-effective treatment option for slash-and-burn farmers. The study shows the relevance of understanding social factors to improve the uptake of public health interventions and calls for contextually adapted strategies for malaria elimination in ethnic minority populations in Vietnam and similar settings.

The first newborn patient with SARS-CoV-2 variant B.1.1.7 identified in Viet Nam: treatment and care practices.

SARS-CoV-2 variant B.1.1.7, first detected in September 2020 in the United Kingdom of Great Britain and Northern Ireland, has spread quickly to many countries around the world. While some publications have described the clinical features of adult patients with the B.1.1.7 variant, little information is available on newborn patients. We report the clinical characteristics, treatment and care practices for a 21-day-old newborn patient who was confirmed to be infected with SARS-CoV-2 variant B.1.1.7 in Viet Nam during contact tracing after her father was confirmed to be infected with SARS-CoV-2. The patient displayed no symptoms of COVID-19 on admission but 3 days later developed diarrhoea, vomiting, a runny nose and a productive cough. These symptoms lasted for 3 days before becoming milder for 1 day and then stopping until discharge. During treatment, the patient received Vietnamese traditional herbal peppermint extracts for cough and digestive probiotics for diarrhoeal symptoms. A saltwater solution (Sterimar 0.9%) was used to clean the patient's sinuses. The patient was cared for and fed breastmilk by her mother, who was provided with personal protective equipment, including sterilized infant equipment, medical masks and hand sanitizer, during hospitalization. The patient's mother tested negative for SARS-CoV-2 throughout hospitalization. In conclusion, we found no severely abnormal clinical symptoms in a newborn infected with SARS-CoV-2 variant B.1.1.7 during treatment. Our case suggests that newborn patients with the B.1.1.7 variant can receive exclusive breastmilk feeding if sufficient preventive measures are provided for both mother and child.

COVID-19 Stressors on Migrant Workers in Vietnam: Cumulative Risk Consideration.

This study explored the impact of COVID-19 on migrant workers in Vietnam, using a cumulative risk assessment (CRA) framework which comprises four domains (workplace, environment, individual and community). A cross-sectional study was conducted. Data were collected in 2020 through a self-administered questionnaire with 445 domestic migrant workers in two industrial zones in two northern provinces (Bac Ninh and Ninh Binh) in Vietnam. The majority of migrant workers were female (65.2%), aged between 18 and 29 years old (66.8%), and had high school or higher education level qualifications. Most migrant workers had good knowledge about preventive measures (>90%) and correct practices on COVID-19 prevention (81.1%). Three health risk behaviors were reported: 10% of participants smoked, 25% consumed alcohol and 23.1% were engaged in online gaming. In terms of workplace, occupational working conditions were good. Noise was the most commonly reported hazard (29%). Regarding environment, about two-thirds of migrant workers lived in a small house (<36 m2). Most participants (80.4%) lived with their families. About community domain, many reported low salary or losing their job during January-July, 2020. Most migrants received information about COVID-19. The migrant workers suffered from poor health and low occupational safety, fear of job loss and income cut, poor housing and living conditions and limited access to public services. The holistic approach to address stressors is recommended to improve health and safety of migrant workers.

Depression, stigma and quality of life in people with drug-susceptible TB and drug-resistant TB in Vietnam.

BACKGROUND: Drug resistance poses a major barrier to global control of TB - a leading infectious cause of death. Depression and stigma occur commonly among people with TB. However, the relationship between drug-resistant forms of TB, depression and stigma are not well understood.OBJECTIVE: To compare depression, stigma and health-related quality of life (HRQoL), among people with drug-susceptible TB (DS-TB) and multidrug-resistant TB (MDR-TB).METHODS: A cross-sectional study of people treated for DS-TB and MDR-TB in four provinces of Vietnam. The survey included a stigma scale (Vietnamese Tuberculosis Stigma Scale), depression scale (9-item Patient Health Questionnaire) and HRQoL scale (Functional Assessment of Chronic Illness Therapy - Tuberculosis). Differences between the two populations were compared using linear regression.RESULTS: Eighty-one people with DS-TB and 315 people with MDR-TB participated in the study. People with MDR-TB had a higher prevalence of depression than those with DS-TB (difference 17.8%, χ² 8.64). The mean depression and stigma scores were higher for people with MDR-TB than those with DS-TB (adjusted difference [AD] 8.6 and 7.6 respectively). People with MDR-TB reported lower HRQoL than those with DS-TB (AD -23.8).CONCLUSION: Depression and stigma are common among people with TB in Vietnam. Strategies to prevent and treat depressive symptoms and stigma in people with TB are critical to a holistic, patient-centred approach to care.

Preconception micronutrient supplementation positively affects child intellectual functioning at 6 y of age: A randomized controlled trial in Vietnam.

BACKGROUND: Although there is growing evidence on the role of preconception nutrition for birth outcomes, very few studies have evaluated the long-term effects of nutrition interventions during the preconception period on offspring cognitive outcomes. OBJECTIVE: We evaluate the impact of preconception weekly multiple micronutrients (MMs) or iron and folic acid (IFA) supplementation compared with folic acid (FA) alone on offspring intellectual functioning at age 6-7 y. METHODS: We followed 1599 offspring born to women who participated in a double-blinded randomized controlled trial of preconception supplementation in Vietnam. Women received weekly supplements containing either 2800 µg FA only, 60 mg iron and 2800 µg FA, or MMs (15 micronutrients including IFA) from baseline until conception, followed by daily prenatal IFA supplements until delivery. We used the Wechsler Intelligence Scale for Children to measure full-scale IQ (FSIQ) and 4 related domains of intellectual functioning [Verbal Comprehension Index (VCI), Perceptual Reasoning Index (PRI), Working Memory Index (WMI), and Processing Speed Index (PSI) scores] at 6-7 y. Group comparisons were done using ANOVA tests for all children and the subgroup born to women who consumed the supplements ≥26 wk before conception (per-protocol analyses). RESULTS: The final sample with data at 6-7 y (n = 1321) was similar for baseline maternal and offspring birth characteristics and age at follow-up by treatment group. Compared with the offspring in the FA group, those in the MM group had higher FSIQ (ß = 1.7; 95% CI: 0.1, 3.3), WMI (ß = 1.7; 95% CI: 0.2, 3.2), and PSI (ß = 2.5; 95% CI: 0.9, 4.1). Similar findings were observed in the per-protocol analyses. There were no significant differences by treatment group for VCI and PRI. CONCLUSIONS: Preconception supplementation with MMs improved certain domains of intellectual functioning at age 6-7 y compared with FA. These findings suggest the potential for preconception micronutrient interventions to have long-term benefits for offspring cognition.

[The association between aeroallergenic structures and allergic rhinitis: a study on northern Vietnam]. / Assotsiatsiya mezhdu strukturami aeroallergenov i allergicheskim rinitom: issledovanie o severe V'etnama.

Recently, there has been an increase in the number of patients with allergic rhinitis (AR) and the number of publications devoted to this problem is increasing. The main etiological factors of AR are pollen of trees, meadow and weeds, as well as mold spores, household allergens and epidermis of animals. Epidemiological studies have found that the prevalence and structure of AR are influenced by regional characteristics, such as the climatic and geographical and social characteristics of the region, and successively therapeutic and preventive algorithms in AR are also different. AIM: To examine the phenotype of the incidence of AR in connection with the characteristics of aeroallergens under the influence of climatic and geographical conditions in northern Vietnam, to make a new contribution to knowledge about AR in Asia and to increase the effect of treatment and prevention in this territory. MATERIALS AND RESEARCH METHODS: The study was conducted in the period from 06.2018 to 09.2018 on the basis of the ENT department of Thainguyen Central Hospital, Vietnam. A total of 556 patients with pathology of ENT organs aged 18 to 70 years were examined, 158 cases of chronic rhinitis were revealed. Among data from 158 patients, 64 patients were diagnosed with AR. We used otorhinolaryngological examination, a standard specific allergological examination and carried out aeropolyneological research in the city of the northern Vietnam, from 06.2018 to 06.2019. RESULT: The aerobiological spectrum is dominated by pollen from the families Moraceae, Urticaceae, Poaceae, Acacia, Artemisia, fern spores and fungal spores from the genus Alternaria. Among patients with chronic rhinitis, 40% were diagnosed with AR, 98.44% of them year-round or perennial AR, with predominant sensitization to house dust mites and molds, much more often to plant pollen. Among 9 (14.06%) patients diagnosed with a polyp of the nasal cavity, 6 (9.37%) patients had increased levels of specific IgE in the blood to a mixture of molds. Sensitization in patients with AR with hypertrophy of the mucous membrane of the nasal cavity is predominant on house dust. CONCLUSION: Predominantly, AR in northern Vietnam was year-round. Especially the connection between the formation of a polyp of the nasal cavity and hypersensitivity to fungal spores has been indicated, which may also indicate the role of social factors in further recommendations for the diagnosis, treatment and prevention of AR in patients living in North Vietnam.

Female breast cancer in New South Wales, Australia, by country of birth: implications for health-service delivery.

BACKGROUND: NSW has a multicultural population with increasing migration from South East Asia, the Western Pacific and Eastern Mediterranean. OBJECTIVE: To compare cancer stage, treatment (first 12 months) and survival for 12 country of birth (COB) categories recorded on the population-based NSW Cancer Registry. DESIGN: Historic cohort study of invasive breast cancers diagnosed in 2003-2016. PATIENTS: Data for 48,909 women (18+ ages) analysed using linked cancer registry, hospital inpatient and Medicare and pharmaceutical benefits claims data. MEASUREMENT: Comparisons by COB using multivariate logistic regression and proportional hazards regression with follow-up of vital status to April 30th, 2020. RESULTS: Compared with the Australia-born, women born in China, the Philippines, Vietnam and Lebanon were younger at diagnosis, whereas those from the United Kingdom, Germany, Italy and Greece were older. Women born in China, the Philippines, Vietnam, Greece and Italy lived in less advantaged areas. Adjusted analyses indicated that: (1) stage at diagnosis was less localised for women born in Germany, Greece, Italy and Lebanon; (2) a lower proportion reported comorbidity for those born in China, the Philippines and Vietnam; (3) surgery type varied, with mastectomy more likely for women born in China, the Philippines and Vietnam, and less likely for women born in Italy, Greece and Lebanon; (4) radiotherapy was more likely where breast conserving surgery was more common (Greece, Italy, and Lebanon) and the United Kingdom; and (5) systemic drug therapy was less common for women born in China and Germany. Five-year survival in NSW was high by international standards and increasing. Adjusted analyses indicate that, compared with the Australian born, survival from death from cancer at 5 years from diagnosis was higher for women born in China, the Philippines, Vietnam, Italy, the United Kingdom and Greece. CONCLUSIONS: There is diversity by COB of stage, treatment and survival. Reasons for survival differences may include cultural factors and healthier migrant populations with lower comorbidity, and potentially, less complete death recording in Australia if some women return to their birth countries for treatment and end-of-life care. More research is needed to explore the cultural and clinical factors that health services need to accommodate.

Multiple micronutrient supplementation improves micronutrient status in primary school children in Hai Phong City, Vietnam: a randomised controlled trial.

We aimed to determine the efficacy of multiple micronutrient supplementation on the biomarkers of iron, zinc, and vitamin A status across anthropometric status categories in Vietnamese school children. In this 22-week randomised controlled trial, 347 undernourished, normal weight, or overweight/obese children aged 6-9 years were allocated to receive every school day a multiple micronutrient supplement (10 mg iron, 10 mg zinc, 400 µg vitamin A) or a placebo. Haematological indices; circulating ferritin, zinc, and retinol (corrected for inflammation); and C-reactive protein were measured at baseline and 22 weeks. At week 22, linear mixed models showed that mean corpuscular volume increased by 0.3 fL, serum ferritin by 9.1 µg/L, plasma zinc by 0.9 µmol/L, and plasma retinol by 15%, and the prevalence of zinc deficiency decreased by 17.3% points in the intervention group compared to placebo. No intervention effects were found for other haematological indices, or the prevalence of anaemia. Multiple micronutrient supplementation for 22 weeks improved the biomarkers of zinc and vitamin A status and some biomarkers of iron status, and reduced the prevalence of zinc deficiency in Vietnamese school children.Trial registration: This trial was registered on 06/09/2016 at www.anzctr.org.au as ACTRN12616001245482.

Feasibility, benefits, and cost-effectiveness of adding universal hepatitis B and syphilis testing to routine antenatal care services in Thai Nguyen province, Vietnam.

Pregnant women in Vietnam have a high prevalence of hepatitis B virus (HBV) and low prevalence of human immunodeficiency virus (HIV) and syphilis. This study aims to assess the feasibility and benefit of universal testing for HIV, HBV and syphilis in antenatal care (ANC) services. A pilot project was conducted in the Thai Nguyen province of Vietnam between 2012 and 2014. HIV, HBV and syphilis testing were offered to pregnant women. Interventions to eliminate mother-to child-transmission (MTCT) of the three pathogens were provided to infected mothers and their infants. Descriptive analysis was conducted, and the number of infections averted from integrating hepatitis B tests into ANC was estimated. Testing coverage for HIV, HBV and syphilis for the cohort of pregnant women during the pilot project was 98%. Prevalence of HIV, HBV and syphilis infections in this cohort was 0.14%, 7.8%, and 0.03%, respectively. No infant was infected with HIV or syphilis, while HBV infection was diagnosed in 27 infants (13.9%). An estimated 23 mother to child HBV infections were prevented by integrated interventions. The triple prevention of mother-to-child transmission of HIV, HBV and syphilis is feasible. Investment in the expansion of the integrated approach is required to achieve the goal of eliminating MTCT.

Trends in antimicrobial resistance in Neisseria gonorrhoeae in Hanoi, Vietnam, 2017-2019.

BACKGROUND: Antimicrobial resistance (AMR) in Neisseria gonorrhoeae is an emerging global health threat. Surveillance of AMR in N. gonorrhoeae in the Western Pacific Region is important, as resistant strains have typically emerged from this region. There are sparse data regarding antibiotic susceptibility of N. gonorrhoeae from Vietnam. This study aimed to provide updated data on antibiotic susceptibilities in N. gonorrhoeae isolates from Hanoi, Vietnam. METHODS: From 2017 to 2019, 409 N. gonorrhoeae clinical isolates were collected at the National Hospital for Venereology and Dermatology in Hanoi, Vietnam. Antibiotic susceptibility testing was performed by disk diffusion method according to the Clinical and Laboratory Standards Institute (CLSI) protocol. The zone diameters of inhibition were recorded and interpreted according to standard CLSI criteria, except for azithromycin, due to the absence of CLSI interpretation. Categorical variables were analyzed by Chi-square and Fisher's exact tests. Linear regression was used to evaluate zones of inhibition by year. RESULTS: Among the 409 isolates, no isolates were susceptible to penicillin, 98.3% were resistant to ciprofloxacin, and all isolates were susceptible to spectinomycin. There were 122/407 (30.0%) isolates resistant to azithromycin and there was an association between resistance and year (p <  0.01), ranging from 15.3% of isolates in 2017 to 46.7% of the isolates in 2018. Resistance to cefixime was found in 13/406 (3.2%) of isolates and there was no association by year (p = 0.30). Resistance to ceftriaxone occurred in 3/408 (0.7%) of isolates. Linear regression indicated the zone of inhibition diameters decreased by 0.83 mm each year for ceftriaxone (95% CI: - 1.3, - 0.4; p <  0.01) and decreased by 0.83 mm each year (95% CI: - 1.33, - 0.33; p <  0.01) for azithromycin; the association was not significant for cefixime (p = 0.07). CONCLUSIONS: We found decreasing susceptibility of N. gonorrhoeae to ceftriaxone and azithromycin, as well as a high prevalence of resistance to azithromycin, among isolates in Hanoi, Vietnam from 2017 to 2019. The trends of decreasing susceptibility to first-line treatments are concerning and highlight the urgency of addressing antimicrobial resistance in N. gonorrhoeae. Expanded surveillance efforts within the Western Pacific Region are critical to monitoring trends and informing treatment guidelines.

The first cohort of the COVID-19 patients in Vietnam and the national response to the pandemic.

The COVID-19 pandemic is a novel infectious disease pandemic with the agent SARS-CoV-2 virus which is currently affecting and causing damage globally. The outbreak has been crossing over 200 countries in the world. In the situation of the outbreak of COVID-19, Vietnam has first sixteen typical cases confirmed positive updated to Feb 28th, 2020. After completely applying the medical prevention and active control, Vietnam has the ability to take control of the outbreak of COVID-19 as a recent of WHO assessment. Vietnam has been reported as an effective country for prevention and control the outbreak of COVID-19. We retroactive reviewed our experience with 16 positive cases isolation. This article aims to present the first cohort of COVID-19 patients updated to Feb 28th, 2020 in Vietnam and sharing the national response to the pandemic.

The role of animals as a source of antimicrobial resistant nontyphoidal Salmonella causing invasive and non-invasive human disease in Vietnam.

BACKGROUND: Nontyphoidal Salmonella (NTS) are associated with both diarrhea and bacteremia. Antimicrobial resistance (AMR) is common in NTS in low-middle income countries, but the major source(s) of AMR NTS in humans are not known. Here, we aimed to assess the role of animals as a source of AMR in human NTS infections in Vietnam. We retrospectively combined and analyzed 672 NTS human and animal isolates from four studies in southern Vietnam and compared serovars, sequence types (ST), and AMR profiles. We generated a population structure of circulating organisms and aimed to attribute sources of AMR in NTS causing invasive and noninvasive disease in humans using Bayesian multinomial mixture models. RESULTS: Among 672 NTS isolates, 148 (22%) originated from human blood, 211 (31%) from human stool, and 313 (47%) from animal stool. The distribution of serovars, STs, and AMR profiles differed among sources; serovars Enteritidis, Typhimurium, and Weltevreden were the most common in human blood, human stool, and animals, respectively. We identified an association between the source of NTS and AMR profile; the majority of AMR isolates were isolated from human blood (p < 0.001). Modelling by ST-AMR profile found chickens and pigs were likely the major sources of AMR NTS in human blood and stool, respectively; but unsampled sources were found to be a major contributor. CONCLUSIONS: Antimicrobial use in food animals is hypothesized to play role in the emergence of AMR in human pathogens. Our cross-sectional population-based approach suggests a significant overlap between AMR in NTS in animals and humans, but animal NTS does explain the full extent of AMR in human NTS infections in Vietnam.

Perceptions About Mindfulness and Text Messaging for Smoking Cessation in Vietnam: Results From a Qualitative Study.

BACKGROUND: With 15.6 million smokers, Vietnam is one of the top 10 largest cigarette-consuming countries in the world. Unfortunately, smoking cessation programs are still scarce in Vietnam. Mindfulness-based and text messaging-based interventions have been increasingly used in smoking cessation studies in developed countries, with promising results. Given the exponential growth of mobile phone usage in Vietnam in recent years, mobile health interventions could be a potential strategy to increase smoking cessation in Vietnam. However, substantial cultural adaptations are needed to optimize the effectiveness of these interventions among Vietnamese smokers. OBJECTIVE: This study aims to involve qualitative research to inform the development of a mindfulness-based text messaging smoking cessation intervention for Vietnamese smokers. METHODS: A total of 10 focus groups were conducted with 71 Vietnamese male smokers aged between 18 and 65 years (5-9 participants per focus group). Overall, 5 focus groups were conducted with smokers who had the intention to quit (ie, preparation stage of change in the transtheoretical model), and 5 focus groups were conducted with smokers who did not have the intention to quit (contemplation or precontemplation stage). The focus groups were audio recorded, transcribed verbatim, and analyzed using NVivo 12 software (QSR International). RESULTS: The major themes included smoking triggers, barriers and facilitators for quitting, the perceptions of text messaging and mindfulness approaches for smoking cessation, and suggestions for the development of a text messaging-based smoking cessation program. Common smoking triggers included stress, difficulties concentrating, and fatigue. Frequently encountering other people who were smoking was a common barrier to quitting. However, participants indicated that concerns about the harmful effects of smoking on themselves and their wives and children, and encouragement from family members could motivate them to quit. The participants preferred diverse message content, including information about the consequences of smoking, encouragement to quit, and tips to cope with cravings. They suggested that text messages be clear and concise and use familiar language. Most smokers perceived that mindfulness training could be useful for smoking cessation. However, some suggested that videos or in-person training may also be needed to supplement teaching mindfulness through text messages. CONCLUSIONS: This study provides important insights to inform the development of a text messaging-based smoking cessation program that incorporates mindfulness for Vietnamese male smokers. The results could also be useful for informing similar programs in other low- and middle-income countries.
