Complete genome characterization of two wild-type measles viruses from Vietnamese infants during the 2014 outbreak
A large measles virus outbreak occurred across Vietnam in 2014. We identified and obtained complete measles virus genomes in stool samples collected from two diarrheal pediatric patients in Dong Thap Province. These are the first complete genome sequences of circulating measles viruses in Vietnam during the 2014 measles outbreak
Genome sequences of a novel Vietnamese bat bunyavirus
To document the viral zoonotic risks in Vietnam, fecal samples were systematically collected from a number of mammals in southern Vietnam and subjected to agnostic deep sequencing. We describe here novel Vietnamese bunyavirus sequences detected in bat feces. The complete L and S segments from 14 viruses were determined
Applying lessons learnt from research of child pneumonia management in Vietnam
Pneumonia is the leading cause of paediatric hospitalisation in Vietnam, placing a huge burden on the health care system. Pneumonia is also the main reason for antibiotic use in children. Unfortunately many hospital admissions for child pneumonia in Vietnam are unnecessary and inappropriate use of antibiotics is common, as in the rest of Asia, with little awareness of its adverse effects. We explored the value of an alternative approach that, instead of focusing on the identification of children with severe bacterial pneumonia, focuses on the identification of children with 'unlikely bacterial pneumonia' to improve patient care and rational antibiotic use. Implementing improved models of care require pragmatic management algorithms that are well validated, but it is ultimately dependent on financial structures, management support and evidence-based training of healthcare providers at all relevant levels. Apart from better case management, sustained reductions in the pneumonia disease burden also require increased emphasis on primary prevention
Pharmacists' training to improve inhaler technique of patients with COPD in Vietnam
Tu-Son Nguyen,1,2 Thi Lien Huong Nguyen,1 Thi Thuy Van Pham,1 Susan Hua,2 Quy Chau Ngo,3 Shu Chuen Li2 1Department of Clinical Pharmacy, Hanoi University of Pharmacy, Hanoi, Vietnam; 2School of Biomedical Sciences and Pharmacy, Faculty of Health and Medicine, University of Newcastle, Callaghan, NSW, Australia; 3Respiratory Centre, Bach Mai Hospital, Hanoi, Vietnam Background: Incorrect use of inhalers is very common and subsequently leads to poor control of COPD. Among health care providers, pharmacists are in the best position to educate patients about the correct use of inhaler devices. Objective: The objective of this study was to evaluate the impact of pharmacist-led training on the improvement of inhaler technique for COPD patients in Vietnam. Patients and methods: For this pre- and post-intervention study, standardized checklists of correct use of metered-dose inhalers (MDIs) and dry powder inhalers (DPIs) were used to evaluate the inhaler technique. A scoring system (maximum score =8) was applied before and after training to guarantee assessment uniformity among pharmacists. Three methods including “face-to-face training”, “teach-back” and “technique reminder label” were used. After the baseline evaluation (T0), the inhaler technique was reassessed after 1 month (T1), 3 months (T2), 6 months (T3) and 12 months (T4). Results: A total of 211 COPD patients participated in the study. Before the training, a high rate of errors was recorded. After the training, the percentage of patients using MDIs and DPIs perfectly increased significantly (p<0.05). The mean technique score for MDIs and DPIs improved from 6.0 (T0) to 7.5 (T3) and 6.9 (T4) and 6.7 (T0) to 7.6 (T3) and 7.2 (T4), respectively (p<0.05). The average training time was 6 minutes (T0) and 3 minutes (T3), respectively. Conclusion: Pharmacist-led comprehensive inhaler technique intervention program using an unbiased and simple scoring system can significantly improve the inhaler techniques in COPD patients. Our results indicated a 3-month period as the optimal time period between training and retraining for maintaining the correct inhaler technique. The training would be highly feasible and suitable for implementing in the clinical setting. Our model of pharmacist-led training should be considered as an effective solution for managing COPD patients and better utilization of health care human resources, especially in a developing country like Vietnam.

Knowledge, attitudes, practices and emotional reactions among residents of avian influenza (H5N1) hit communities in Vietnam
Background Awareness of individualsâ knowledge and predicting their behavior and emotional reactions is crucial when evaluating clinical preparedness for influenza pandemics with a highly pathogenic virus. Knowledge, attitude, and practice (KAP) relating to avian influenza (H5N1) virus infection among residents in communities where H5N1 patients occurred in Vietnam has not been reported. Methods and Principal Findings Face-to-face interviews including KAP survey were conducted in Bac Kan province, located in the northeast mountainous region of Vietnam. Participants were residents who lived in a community where H5N1 cases have ever been reported (event group, nâ=â322) or one where cases have not been reported (non-event group, nâ=â221). Data on emotional reactions of participants and healthcare-seeking behavior after the event in neighboring areas were collected as well as information on demographics and environmental measures, information sources, and KAP regarding H5N1. These data were compared between two groups. Higher environmental risk of H5N1 and improper poultry-handling behaviors were identified in the event group. At the time of the event, over 50% of the event group sought healthcare for flu-like symptoms or because they were scared. Awareness of the event influenced KAP scores. Healthcare-seeking behavior and attention to H5N1 poultry outbreaks diminished in the event group as time passed after the outbreak compared with the non-event group. Factors that motivated participants to seek healthcare sooner were knowledge of early access to healthcare and the risk of eating sick/dead poultry, and perception of the threat of H5N1. Conclusions Awareness of H5N1 patients in neighboring areas can provoke panic in residents and influence their healthcare-seeking behavior. Periodic education to share experiences on the occurrence of H5N1 patients and provide accurate information may help prevent panic and infection and reduce mortality. Local conditions should be taken into account when emphasizing the need for early access to healthcare

Identification and characterization of Coronaviridae genomes from Vietnamese bats and rats based on conserved protein domains
The Coronaviridae family of viruses encompasses a group of pathogens with a zoonotic potential as observed from previous outbreaks of the severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus. Accordingly, it seems important to identify and document the coronaviruses in animal reservoirs, many of which are uncharacterized and potentially missed by more standard diagnostic assays. A combination of sensitive deep sequencing technology and computational algorithms is essential for virus surveillance, especially for characterizing novel- or distantly related virus strains. Here, we explore the use of profile Hidden Markov Model-defined Pfam protein domains (Pfam domains) encoded by new sequences as a Coronaviridae sequence classification tool. The encoded domains are used first in a triage to identify potential Coronaviridae sequences and then processed using a Random Forest method to classify the sequences to the Coronaviridae genus level. The application of this algorithm on Coronaviridae genomes assembled from agnostic deep sequencing data from surveillance of bats and rats in Dong Thap province (Vietnam) identified thirty-four Alphacoronavirus and eleven Betacoronavirus genomes. This collection of bat and rat coronaviruses genomes provided essential information on the local diversity of coronaviruses and substantially expanded the number of coronavirus full genomes available from bat and rats and may facilitate further molecular studies on this group of viruses
