Mapping COVID-19-related research from Vietnam: a scoping review: Mapping COVID-19 related research in Vietnam

Introduction: The situation of COVID-19 pandemic is becoming more complex. The research institutes should focus on the most important challenge related to this outbreak at the national level. We aim to realize this scoping review to map publications on COVID-19 in Vietnam in order to guide research priorities and policies in the country. Methods: This study was conducted at the Thai Binh University of Medicine and Pharmacy, from May to August 2020, according to the guidance for conducting systematic scoping review. Results: A total of 72 studies met the inclusion criteria. The most frequent publications were original articles (27.8%), followed by letter to editor/correspondence (26.4%). According to the research priorities for COVID-19 set by the WHO, 41.7% studies focused on control and prevention of COVID-19, but none of studies on personal protective equipment or protocol for healthcare workers’ safety were conducted. 12.5% studies carried out a thorough investigation into epidemiology of the COVID-19 pandemic in Vietnam. Virology and genomics, natural history of the virus and its transmission in Vietnam were described by 18.1% papers. Only one study was conducted in terms of development for candidate therapeutics. Conclusion: We call for national investigation on treatment against SARS-CoV-2 and protocol for medical staff protection. The government and academic institutions should work in collaboration with international stakeholders, including the WHO, to combat together the COVID-19

Field-induced spin-liquid-like state in a magnetic honeycomb lattice

Physical Review B. Volume 98, Issue 22, 18 December 2018, Article number 220407.© 2018 American Physical Society. Quantum fluctuations in magnetic lattices can yield a quantum spin-liquid (QSL) state, where no long-range order appears even at zero temperature. The variety of mechanisms that can generate the spin-liquid state and the more exotic QSL state remain unclear, however. Here, we report a magnetic honeycomb system, BaCo2(P1-xVx)2O8, in which the spin correlations can be tuned by the disorder, leading to different magnetic behaviors. At low x, the material has a spin-glass ground state that appears to be due to coexisting and competing correlations. We have found that an external magnetic field can introduce spin-liquid-like behavior for some members of the solid solution, testified by the magnetic and thermodynamic experiments. Our results suggest that structural geometry, chemical disorder, and external field may help enhance quantum fluctuations in magnetic honeycomb materials

Clinical and Laboratory Characteristics of Kawasaki Disease and COVID-19-Related Multisystem Inflammatory Syndrome in Children

International audienceGeographical and racial factors constitute important distinctions between Kawasaki disease (KD) and multisystem inflammatory syndrome in children (MIS-C), but no study has been conducted in Vietnam. Forty-one children with KD from January 2018 to July 2020 and 42 with KD/MIS-C from August 2020 to December 2022 were included in this study. Of the patients, 52.3% were aged between 12 and 35 months. Only two were aged over 5 years, and both were belong to the KD/MIS-C group. A 59.5% of the patients were male. Apart from fever, all symptoms tended to be more frequent in patients with KD/MIS-C. The prevalence of diffuse skin rash, hand and foot edema or erythema and gastrointestinal signs was significantly higher in patients hospitalized with KD/MIS-C. There was no significant difference in laboratory findings between the two groups. Coronary artery dilation was more frequently observed in patients with KD/MIS-C compared to those with KD (40.5% vs. 14.6%, P = 0.009)

Effect of the COVID-19 Outbreak on the Incidence of Other Respiratory and Gastrointestinal Infections in Children in Thai Binh, Vietnam in 2020

International audienceAbstract Introduction To evaluate the impact of COVID-19 mitigation measures on the total number of consultations for respiratory and gastrointestinal infections among children under 16 years in Thai Binh Pediatric Hospital, Vietnam during the year 2020. Methods A retrospective study was carried out to review consecutive consultations occurring in children admitted from January 01, 2016 to December 31, 2020. All medical records were collected from the central numeric database of the hospital. Diagnoses were documented according to the International Classification of Diseases 10 criteria. Results 436,276 children consulted at the outpatient department during the period of study. A gradual increase in the total number of outpatients was observed from 2016 to 2019, including those consulting for respiratory and gastrointestinal infections. However, the total number of outpatients and the numbers of those consulting for respiratory and gastrointestinal infections dramatically decreased in 2020. A significant decrease of respiratory infections relative proportion was observed in 2020 when compared to 2016–2019 ( p < 0.0001). By contrast, the relative proportion of gastrointestinal infections did not significantly vary ( p = 0.91). The proportion of outpatients aged under 5 years was significantly lower in 2020 compared to previous years ( p < 0.0001). The proportion of male patients was significantly higher in 2020 than from 2016 to 2019 ( p = 0.001). Conclusion Public health measures against the COVID-19 pandemic likely decreased the prevalence of other respiratory tract infections. Further studies are needed to validate the effectiveness of each type of measure. Microbiological studies are also recommended, to better understand the effect of preventive measures

The Blast furnace slag properties at different grinding times and its effect on foam concrete properties

The paper presents the blast furnace slag properties at different grinding times by the dry grinding method. The process of fine grinding blast furnace slag is prepared at different times (10 minutes, 20 minutes, 30 minutes, 40 minutes). The results indicated that the main component in BFS is the amorphous structure defined in about 25÷35 degrees (with the appearance of Akermanite at 31.1, Calcite at 29.2 and Aragonite at 26.4). The results also showed that the compressive strength and activity index of blast furnace slag increased significantly after extending the grinding time from 0-40 minutes (corresponding to compressive strength from 51.2 ÷ 7 2.1 MPa at 28 days of age and activity index of blast furnace slag from 91.92% -129.44%). The fine grinding process shows that the particle size of blast furnace slag is significantly reduced. In addition, the paper also presents the effect of finely ground blast furnace slag in 40 minutes on foam concrete properties. Research results show that the use of finely crushed blast furnace slag by the mechanical grinding method to replace sand in foam concrete not only improves the mechanical properties such as compressive strength, flexural strength, the elastic modulus of foam concrete but also protect the environment, reduce product costs

Short-Term Adverse Effects Immediately after the Start of COVID-19 Booster Vaccination in Vietnam

Background: Risk communication is necessary to improve the booster vaccination rate, but Vietnam does not have a system to collect and disclose such information. Therefore, the purpose of this study was to clarify adverse reactions and their frequency in the early period after booster vaccination, and to obtain primary data for improving the booster vaccination rate. Methods: A cross-sectional survey was conducted among adults aged ≥18 years. Clinical data were collected 14 days after booster vaccination by using a standard questionnaire. Results: A total of 1322 participants were included with median age = 23 and sex ratio (Male/Female) = 0.53. AstraZeneca was the most commonly used vaccine for the first and second doses, while Pfizer was the most commonly used vaccine for booster shots. Injection site pain, fatigue, and myalgia were the most common side effect reported (71.9%, 28.1%, and 21.8%, respectively). Compared to previous COVID-19 vaccine injections, 81.9% of participants reported that their symptoms were similar or milder after receiving the booster dose. They were more likely to present injection site pain (OR = 1.43, p p p p = 0.002) were less often reported after booster shots compared to the first and second injections. The severity of symptoms occurring after booster dose versus first and second doses increased significantly with each additional year of age and among participants receiving the Pfizer and Moderna vaccines. Conclusion: Adverse reactions to booster vaccination are minor and their incidence is the same as for the first or the second vaccination. Multicenter studies with larger sample sizes on the side effects and safety of COVID-19 vaccine booster shots need to be conducted to make the population less worried, in order to increase the vaccination rate, to protect individuals’ and communities’ health
