    During his time, Former President Ho Chi Minh had consistently emphasized the central role, position, and competence of the young generation in realizing the Party and the people's revolutionary path. He believed, “The youth are the future owners of the home country. Indeed, the vitality of the home country, whether it is prosperous or wilting, depends largely on the youth.” Before passing, his words had become the guiding principle for leaders of the Communist Party of Vietnam, “Nurturing future revolutionary generations is of utmost importance and necessity.” Especially, given that the functioning of the current market economy has revealed its multiple drawbacks, it is salient to educate and orient the youth following Ho Chi Minh's ideology to produce a young generation that is moral in ethics and efficient in labour.  Article visualizations

    DEMONSTRATING ADAPTABILITY: ROLE MODELLING MULTIDISCIPLINARY LEARNING IN THE LAB, ONLINE AND AT HOME

    In this paper we analyse changes required in the role of laboratory demonstrators to support students across a mid-semester move to online learning in response to COVID-19. ‘Multidisciplinary Laboratories’ is a large (~450 students) first-year, multi-campus course at the University of Newcastle that is organised around two multifaceted investigations: ‘Water – would you drink it?’, and ‘Energy – can it be sustainable?’. The course introduces students each week to diverse disciplinary perspectives, i.e. Environmental Science and Management, Biology, Chemistry, Psychology, Human Geography, Earth Sciences, and Physics. The teaching cohort in each laboratory session (~45 students) comprises a discipline-specific academic lead that changes weekly, and two demonstrators who remain with the class for the whole semester. As laboratories moved online, demonstrators supported students’ learning through synchronous live classes, experiments at home, virtual experiments and asynchronous materials including video tutorials. Importantly, demonstrators have role-modelled for students adaptability under conditions of uncertainty. Analysis of evaluative data including Blackboard engagement records, student surveys and demonstrators’ observations suggests effectively supporting students’ learning required nuanced and important changes in demonstrators’ roles including technical aspects, and techniques for engaging students and facilitating classes

    Mortality from tuberculous meningitis (TBM) remains around 30%, with most deaths occurring within 2 months of starting treatment. Mortality from drug-resistant strains is higher still, making early detection of drug resistance (DR) essential. Targeted next-generation sequencing (tNGS) produces high read depths, allowing the detection of DR-associated alleles with low frequencies. We applied Deeplex Myc-TB-a tNGS assay-to cerebrospinal fluid (CSF) samples from 72 adults with microbiologically confirmed TBM and compared its genomic drug susceptibility predictions to a composite reference standard of phenotypic susceptibility testing (pDST) and whole genome sequencing, as well as to clinical outcomes. Deeplex detected Mycobacterium tuberculosis complex DNA in 24/72 (33.3%) CSF samples and generated full DR reports for 22/24 (91.7%). The read depth generated by Deeplex correlated with semi-quantitative results from MTB/RIF Xpert. Alleles with <20% frequency were seen at canonical loci associated with first-line DR. Disregarding these low-frequency alleles, Deeplex had 100% concordance with the composite reference standard for all drugs except pyrazinamide and streptomycin. Three patients had positive CSF cultures after 30 days of treatment; reference tests and Deeplex identified isoniazid resistance in two, and Deeplex alone identified low-frequency rifampin resistance alleles in one. Five patients died, of whom one had pDST-identified pyrazinamide resistance. tNGS on CSF can rapidly and accurately detect drug-resistant TBM, but its application is limited to those with higher bacterial loads. In those with lower bacterial burdens, alternative approaches need to be developed for both diagnosis and resistance detection

    Multilocus sequence typing of Cryptococcus neoformans var. grubii from Laos in a regional and global context.

    Cryptococcosis causes approximately 180 000 deaths each year in patients with human immunodeficiency virus (HIV). Patients with other forms of immunosuppression are also at risk, and disease is increasingly recognized in apparently immunocompetent individuals. Cryptococcus neoformans var. grubii, responsible for the majority of cases, is distributed globally. We used the consensus ISHAM Multilocus sequence typing (MLST) scheme to define the population structure of clinical C. neoformans var. grubii isolates from Laos (n = 81), which we placed into the global context using published MLST data from other countries (total N = 1047), including a reanalysis of 136 Vietnamese isolates previously reported. We observed a phylogeographical relationship in which the Laotian population was similar to its neighbor Thailand, being dominated (83%) by Sequence Types (ST) 4 and 6. This phylogeographical structure changed moving eastwards, with Vietnam's population consisting of an admixture of isolates dominated by the ST4/ST6 (35%) and ST5 (48%) lineages. The ST5 lineage is the predominant ST reported from China and East Asia, where it accounts for >90% of isolates. Analysis of genetic distance (Fst) between different populations of C. neoformans var. grubii supports this intermediate structure of the Vietnamese population. The pathogen and host diversity reported from Vietnam provide the strongest epidemiological evidence of the association between ST5 and HIV-uninfected patients. Regional anthropological genetic distances suggest diversity in the C. neoformans var. grubii population across Southeast Asia is driven by ecological rather than human host factors. Where the ST5 lineage is present, disease in HIV-uninfected patients is to be expected

    Rifampicin resistant 'Mycobacterium tuberculosis' in Vietnam, 2020–2022

    Objective: We conducted a descriptive analysis of multi-drug resistant tuberculosis (MDR-TB) in Vietnam’s two largest cities, Hanoi and Ho Chi Minh city. Methods: All patients with rifampicin resistant tuberculosis were recruited from Hanoi and surrounding provinces between 2020 and 2022. Additional patients were recruited from Ho Chi Minh city over the same time period. Demographic data were recorded from all patients, and samples collected, cultured, whole genome sequenced and analysed for drug resistance mutations. Genomic susceptibility predictions were made on the basis of the World Health Organization’s catalogue of mutations in Mycobacterium tuberculosis associated with drug resistance, version 2. Comparisons were made against phenotypic drug susceptibility test results where these were available. Multivariable logistic regression was used to assess risk factors for previous episodes of tuberculosis. Results: 233/265 sequenced isolates were of sufficient quality for analysis, 146 (63 %) from Ho Chi Minh City and 87 (37 %) from Hanoi. 198 (85 %) were lineage 2, 20 (9 %) were lineage 4, and 15 (6 %) were lineage 1. 17/211 (8 %) for whom HIV status was known were infected, and 109/214 (51 %) patients had had a previous episode of tuberculosis. The main risk factor for a previous episode was HIV infection (odds ratio 5.1 (95 % confidence interval 1.3–20.0); p = 0.021). Sensitivity for predicting first-line drug resistance from whole genome sequencing data was over 90 %, with the exception of pyrazinamide (85 %). For moxifloxacin and amikacin it was 50 % or less. Among rifampicin-resistant isolates, prevalence of resistance to each non-first-line drug was < 20 %. Conclusions: Drug resistance among most MDR-TB strains in Vietnam’s two largest cities is confined largely to first-line drugs. Living with HIV is the main risk factor among patients with MDR-TB for having had a previous episode of tuberculosis

    Drivers of antibiotic use in Vietnam: implications for designing community interventions.

    INTRODUCTION: Antimicrobial resistance is a global challenge that threatens our ability to prevent and treat common infectious diseases. Vietnam is affected by high rates of antimicrobial resistant infections, driven by the overuse of antibiotics and the Vietnamese government has recognised antimicrobial resistance as a health security priority. This study aimed to understand how people in Vietnam use antibiotics in community settings, and the factors that impact their practices and decision-making regarding antibiotics. METHODS: We conducted 43 qualitative in-depth interviews with 50 community members in two urban and two rural sites in Vietnam. We conducted iterative, inductive thematic analysis alongside data collection through a process of systematic debriefings based on detailed interview summaries. Through this process, we developed a coding framework that was then applied to transcribed interview data. RESULTS: Frequent and indiscriminate use of antibiotics was driven by the powerful appeal that antibiotics held for many Vietnamese consumers. Consumers were discerning in making decisions in their purchase and use of antibiotics. Consumers' decisions were affected by perceptions of what constitutes high-quality medicine (effective, strong, accessible and affordable); privileging symptom control over diagnosis; social constructions of antibiotics as a trusted remedy with embodied evidence of prior efficacy, which is reinforced by advice from trusted sources in their community; and varied, generally incomplete, understanding of the concept of antibiotic resistance and its implications for individuals and for public health. CONCLUSION: Antibiotic use at the community and primary care level in Vietnam is driven by community members' social and economic response to what constitutes effective healthcare, rather than biomedical logic. Community-based interventions to reduce unnecessary antibiotic use need to engage with the entangled socio-structural factors that 'resist' current public health efforts to ration antibiotic use, alongside biomedical drivers. This study has informed the design of a community-based trial to reduce unnecessary antibiotic use

    Evaluation of awake prone positioning effectiveness in moderate to severe COVID-19

    Get PDF
    Evidence mainly from high income countries suggests that lying in the prone position may be beneficial in patients with COVID-19 even if they are not receiving invasive ventilation. Studies indicate that increased duration of prone position may be associated with improved outcomes, but achieving this requires additional staff time and resources. Our study aims to support prolonged (≥ 8hours/day) awake prone positioning in patients with moderate to severe COVID-19 disease in Vietnam. We use a specialist team to support prone positioning of patients and wearable devices to assist monitoring vital signs and prone position and an electronic data registry to capture routine clinical data
