Objective: Increased fast food consumption can have adverse effects on health and well-being among adolescents, posing a significant public health concern. The school closures due to the coronavirus disease-2019 (COVID-19) pandemic have led to changes in eating patterns and disrupted a balance diet among adolescents. This study explored the factors associated with fast food consumption among adolescents during school closures due to the COVID-19 pandemic.
Methods: A total of 1,710 middle and high school students in Gwangju, South Korea participated in a cross-sectional survey. The self-administered questionnaire included items assessing dietary intake, physical activity, sleep, media use, and sociodemographic information. The Patient Health Questonnaire-9, Generalized Anxiety Disorder-7, and three item version of the UCLA Loneliness Scale were also administered. Multivariable logistic regression was used to examine the factors associated with increased fast food consumption.
Results: Approximately 34.6% of the surveyed adolescents reported increased fast food consumption during school closures, as well as increased sleep duration, increased sedentary behaviors including watching TV and using the internet, and reduced physical activity. Multivariable logistic regression analysis revealed that fast food consumption during school closures was associated with irregular patterns of main meals and sleep, decreased physical activity, increased internet use, and a lack of daytime adult supervision.
Conclusion: Our results highlight the need for dietary and lifestyle monitoring and guidelines to promote health among adolescents, especially during school closures. In conclusion, nutrition intervention programs aiming to limit fast food consumption and enhance healthy dietary habits among adolescents during long-term school closures are warranted.

Thrips can damage over 200 species across 62 plant families, causing significant economic losses worldwide. Their tiny size, rapid reproduction, and wide host range make them prone to outbreaks, necessitating precise and efficient population monitoring methods. Existing intelligent counting methods lack effective solutions for tiny pests like thrips.

Melamine is an additive used fraudulently to enrich foods with nitrogen, particularly in the dairy industry. It is also known as the main metabolite or degradation phytosanitary product of cyromazine. However, the numerous incidents involving living beings in aquatic environments, children and pets fed with products made from melamine in China and certain African countries have led to distrust of melamine in food.

Background: The hydrogen sulfide (HS) in spoilage of raw meat poses significant food safety risks to human health. Meanwhile, as a signaling molecule, HS is crucial for maintaining human physiological homeostasis. Thus, the establishment of an efficient method for HS detection is essential for safeguarding human health.

Background: Obesity and the consumption of ultra-processed foods (UPF) are associated with gut microbiota composition and diversity, which may contribute to alterations in the regulation of hormones involved in satiety, given the gut microbiota's role in regulating host appetite. Therefore, this study aimed to investigate the association of gut microbiota composition and alpha-diversity at the genus-level on postprandial changes in satiety hormones, and appetitive measures in individuals with obesity, given either a meal rich in UPF or a meal without UPF.
Methods: Individuals were randomized to two groups: a) a non-UPF meal and b) a UPF meal.

Fungal pathogens pose a growing threat to global health, necessitating rapid and accurate identification methods. Here, liquid atmospheric pressure matrix-assisted laser desorption/ionisation (LAP-MALDI) mass spectrometry (MS) is applied to fast lipid and protein profiling of Candida albicans and Saccharomyces cerevisiae from cultured colonies. Species-specific lipid profiles were observed in the m/z 600-1100 range, dominated by phospholipids as confirmed by tandem mass spectrometry (MS/MS).
