The effect of lockdowns and distant learning on the health-related behaviours of school students in the United Arab Emirates.

BACKGROUND: The COVID-19 pandemic began to affect the world in early 2020. As a preventive measure, schools in the UAE adopted remote learning. This study aimed to assess the effects of the lockdown and remote learning on the health-related behaviours of school students in the UAE. METHODS: A cross-sectional study using an online survey comprising 33 questions related to physical activity, eating, sleeping and screen time was answered by the students' parents. Chi-square tests, paired Student's t tests and frequency tables were used for analysis. RESULTS: A total of 27,754 responses were received: 46.3% of the parents indicated a significant decrease in physical activity; 44.6% indicated an increase in unhealthy snack consumption; and 51.9% indicated decreased food ordering from restaurants. The percentage of students who slept more than 9 hours and those who slept less than 6 hours increased. Screen time increased significantly for both educational and entertainment purposes (P value < 0.0001). CONCLUSION: The study showed changes in the lifestyle and health-related behaviours of school students as indicated by their parents. Risk factors such as a lack of physical activity, increased food consumption, sleeping and screen time were directly affected. Therefore, it is important to further investigate these changes and their effects to help design targeted health education programs and promotion campaigns.

Frondoside A is a potential anticancer agent from sea cucumbers.

Cancer is a leading cause of death worldwide. Although high cure rates are achievable with current available drugs, this is not without side effects. Hence, attention has been shifted to alternative anticancer agents coming from natural products as treatment options. Extracts from marine sea cucumbers have been investigated for such properties. Frondoside A is a natural glycoside extracted from the sea cucumber, Cucumaria frondosa, which has been used as a traditional remedy, recently, the extract was found to have potential anti-tumor properties. This narrative review aimed at critically analyzing and summarizing the literature available regarding Frondoside A anticancer properties. For that, scientific databases such as PubMed, EMBASE, and ScienceDirect were searched for the keywords; Frondoside A, cancer, metastasis, anticancer properties, and sea cucumbers. Articles in languages other than English were excluded from the study. Such review will help researchers to better tailor future experiments and will enrich the knowledge about natural compounds consumed as traditional substances.
