Skinfold thickness is an indicator of body fat, allowing a more detailed description of obesity. In Vietnam, there are no published percentile values for triceps and subscapular skinfold measurements from population-based studies of adolescents. This study aims to establish percentile tables for triceps, subscapular, and triceps + subscapular skinfolds (TSF + SSSF) sum. We used data from a cross-sectional survey conducted in Ho Chi Minh City. BMI, triceps and subscapular skinfold measurements of 2660 students were obtained. The L (Box-Cox transformation), M (median), and S (coefficient of variation) parameters were used to generate exact percentiles. The proportion of overweight was higher in boys (18.4% vs. 8.2%, p < 0.0001). Triceps, subscapular skinfolds, and TSF + SSSF were significantly higher in girls than in boys (p < 0.001). Our results provide sex- and age-specific reference values for skinfold thickness that can be applied as a new complimentary assessment tool for Vietnamese adolescents.

Since the first case of COVID-19 was announced on January 23, there have been only 123 infected cases with zero death confirmed [1,2]. [...]we write this letter to shed more light about epidemiological maps of cases in Vietnam and also provide helpful information for epidemiologists and policy makers to address specific measures in response to the pandemic. While the infection rates of COVID-19 in countries like China and Italy are significantly higher among the elderly, the most cases (79 out of 123) reported in Vietnam have been observed for the young (aged 11 – 40) (Fig. 2).3 The Vietnam response Although Vietnam is not one of the countries with the highest number of confirmed cases, the novel coronavirus outbreak in Vietnam is considered complex and unpredictable. [...]Vietnamese government, personally the Deputy Prime Minister Vu Duc Dam, directed and deployed prevention and control measures rapidly from the early stage in Vinh Phuc province to current situations of the overall national epidemic. To further prevent the spread from overseas, the Vietnamese government has been imposing a series of rigorous measures, including a temporary suspension of entry of all foreigners who have come from or transited through the COVID-19 affected areas, and a new mandatory regulation that all incoming travelers to Vietnam have to be quarantined at centralized facilities for 14 days [4].4 Suggestions for COVID-19 infection control In regard to the 14-day mandatory quarantine, we speculate that this implementation might sooner or later lead to shortage of space for quarantine, especially in the two metropolitan areas, Hanoi and Ho Chi Minh City. [...]the Vietnamese government may consider a combination of strict self-quarantine in the community and use of new technology, such as application of big data and artificial intelligence to improve contact tracing and the management of potentially infected patients.

Understanding the relative contribution of modifiable risk factors to cancer morbidity and mortality is crucial for designing effective cancer prevention and control strategies. Our study estimated cancer-related deaths and disability-adjusted life years (DALYs) lost attributable to potentially modifiable risk factors in Australia using data from the Global Burden of Diseases 2021 study. In 2021, an estimated 20,409 cancer deaths (37.5%) and 431,575 cancer DALYs lost (37.9%) in Australia were attributable to potentially modifiable risk factors. Males had higher modifiable risk attributed to cancer death and DALY rates than females. Behavioral risks accounted for 25.0% of cancer deaths and 26.5% of DALYs. Metabolic risks and environmental/occupational risks accounted for 9.4% and 9.3% of deaths, respectively. Smoking remained the leading attributable risk factor, accounting for 12.2% cancer deaths and 13.1% DALYs lost. Dietary risks accounted for 40.0% of colorectal cancer deaths and DALYs lost. Cervical, larynx, liver, lung, and colorectal cancers had a high proportion of deaths and DALYs lost attributed to modifiable risks. Liver and nasopharyngeal cancers had the highest burden attributed to alcohol use (39.1% and 39.0%, respectively), while 21.3% liver cancer deaths were attributed to drug use. Strengthening public health interventions, such as multi-disciplinary approaches to promote a healthy lifestyle, is required.

Each rectangle represents a patient numbered by the Vietnam Ministry of Health. Because the confirmed cases linked to healthcare-acquired infection have only very recently been revealed and are increasing in Vietnam, several measures have been implemented to stop the spread of the disease in this hospital4: 1. [...]this decrease does not indicate that the outbreak in the hospital has been successfully eliminated. [...]in addition to the measures above, the hospital should take into consideration the following suggestions to stave off widespread coronavirus transmission in this healthcare facility and in the community: 1. Makeshift healthcare facilities are needed to accommodate non–COVID-19 outpatients and visitors as well as HCWs. 2. Because evidence increasingly favors the use of face masks, nonclinical staff should strictly wear new face masks and gloves and should update their daily health status using COVID-19 monitoring apps, such as NCOVI software developed for Vietnamese citizens. 3.

While many nations are struggling to slow the transmission rate of the coronavirus disease 2019 (COVID-19), Vietnam has seen no new locally acquired cases since April 16. After implementing 22 d of nationwide social distancing, on April 23, the government of Vietnam announced the easing of social distancing measures. This allows the country to restart its socio-economic activities in a gradual, prudent manner. Domestic tourism and exports of agricultural and anti-COVID-19 medical products take priority over the other sectors in this postpandemic economic recovery. Importantly, the country needs to stay vigilant on the fight against the disease to prevent a possibility of another outbreak.

Monofloral honey samples (Coffea robusta) from Vietnam were determined for their chemical compositions. This is the first report on the chemical composition and antioxidant activity of coffee honey from Vietnam. These samples were characterized by their high contents of total and reducing sugars, total phenolic contents, and total flavonoid contents. The contents of seven phenolic acids (PAs) were quantified by high performance liquid chromatography (HPLC) and analyzed with the assistance of principle component analysis (PCA) to differentiate the honey samples into groups. The hydroxymethylfurfural (HMF) (0.048–2.933 mg/kg) and free acid contents (20.326–31.163 meq/kg) of coffee honey were lower in Nepal, which reflected the freshness of the honey when conducting this survey. The coffee honey had total sugar and reducing sugar contents 831.711 g/kg and 697.903 g/kg, respectively. The high level of total phenolic (0.642 mg GAE/g) and flavonoid (0.0341 mg GE/g) contents of coffee honey contributed to their antioxidant activity of this honey sample. Among the coffee honey tested, the IC50 of DPPH radical-scavenging activities value was 1.134–17.031 mg/mL, while the IC50 of ABTS radical-scavenging activities value was 115.381–213.769 mg/mL. The phenolic acids composition analysis displayed that gallic acid appeared in high concentrations in all studied honey samples, ranging from 0.037–1.015 mg/kg, and ferulic acid content ranged from 0.193 to 0.276 mg/kg. The content of trigonelline and caffeine in coffee honey samples ranged from 0.314–2.399 mg/kg and 8.946–37.977 mg/kg. The data in this article highlight the relevance of coffee honey as a healthy substance.

The aim of the present study was to determine the phenolics, carotenoids, B-vitamins, and antioxidant activity of nuts and seeds grown in Vietnam. The concentrations of carotenoids and B-vitamins may vary among the nuts and seeds. Watermelon seed contained the highest level of lutein while pumpkin seed was the β-carotene richest sample. Sachi inchi and sunflower seed comprised considerable levels of vitamin B1, B6, and B9. The phenolic analysis revealed that cashew contained the highest total amount of flavonoids (466.04 μg/g), with catechin, epicatechin, and procyanidin B2 predominating over the other flavonoids. Likewise, chlorogenic and neochlorogenic acids made up the highest total amount of phenolic acids in sunflower seed (1870.41 μg/g). Walnut appeared to possess the highest antioxidant activity evaluated by DPPH, ABTS, FRAP, and reducing power assays. The correlation analysis indicated strong positive correlations between total phenolic content with DPPH and FRAP values. Principal component analysis graphically showed the distant positioning of cashew and sunflower seed, highlighting their significantly higher levels of phenolics. The findings of the study would be useful to improve nutrient database contents for flavonoids and phenolic acids as well as to promote the consumption of nut and seed products in Vietnam.

Vietnam, a Southeast Asian country, has documented 1,515 polymerase chain reaction-positive confirmed coronavirus disease 2019 (COVID-19) cases with 35 deaths a year after the first infection recorded in Ha Noi on January 23, 2020. Half of the infected patients are at the age of 21 to 40 y. While numbers of infections in many countries in the region continue to surge, Vietnam is seeing decreases in the number of daily new cases. As a result of COVID-19 trajectory different from the other countries, as of April 23, 2020, Vietnam is no longer under lockdown and is slowly restarting its socioeconomic activities. This report aims to provide a summary of the COVID-19 situation and response to the pandemic in Vietnam.

Very recently, we have reported that more than 60% of the infected cases occurring in a public hospital in Hanoi, the capital of Vietnam, are linked to food delivery of mildly ill or presymptomatic nonclinical staff working at the hospital cafeteria. 2 This has raised a concern that food delivery has a great potential of contributing to the spread of the disease. 3 While more and more people adhere to the shelter-in-place order, delivery workers are fulfilling customer orders. Evidence has shown that presymptomatic or asymptomatic transmission is 1 of the major routes by which the novel coronavirus spreads. 5 Furthermore, 1 study indicates that presymptomatic transmission accounts for 6.4% of 157 locally acquired cases of COVID-19 in Singapore. 6 FIGURE 1 Potential spread of COVID-19 through food delivery service (a), food delivery workers at a takeout restaurant (b), and close contact with a customer (c). Delivery workers should wear new face masks and gloves, and frequently apply hand sanitizers to minimize contamination with the novel coronavirus. 3.

In recent years, novel nanomaterials have received much attention due to their great potential for applications in agriculture, food safety, and food packaging. Among them, graphene and graphene oxide (GO) are emerging as promising nanomaterials that may have a profound impact on food packaging. However, there are some concerns from consumers and the scientific community about the potential toxicity and biocompatibility of nanomaterials. In this study, we investigated the antibacterial properties of GO against human intestinal bacteria. The cytotoxicity of GO was also studied in vitro using the Caco-2 cell line derived from a colon carcinoma. Electron microscopy was used to investigate the morphology of GO and the interaction between GO flakes and Caco-2 cells. GO at different concentrations (10 to 500 μg/ml) exhibited no toxicity against the selected bacteria and a mild cytotoxic action on Caco-2 cells after 24 h of exposure. The results show that weak adsorption of medium nutrients may contribute to GO's low toxicity. This study suggests that GO is biocompatible and has a potential to be used in agriculture and food science, indicating that more studies are needed to exploit its potential applications.
