The quantity and quality of children's digital screen media exposure is an emerging area of early childhood studies because of its strong social relevance, and this has been particularly true since the COVID-19 pandemic. The few existing parental questionnaires on children's digital screen media exposure mainly focus on monolingual children's media habits and address either the quantity or quality of children's media exposure. Inspired by the existing instruments, the current study introduces a new parental questionnaire to comprehensively assess the duration, frequency, content, design, and use of bilingual children's digital screen media exposure at home, before and since the COVID-19 pandemic. Focus group discussions and the first wave of our data collection on 141 3-6 years old Singaporean bilingual children indicate good face validity and internal consistency of the parental questionnaire. Our results reveal substantial differences in children's quantity and quality of daily digital screen media exposure, as well as the discrepancies in their digital media habits between English and their mother tongue languages, before and since the COVID-19 pandemic.

Objectives: To evaluate the predictive role of carotid stiffening, quantified using ultrafast pulse wave velocity (ufPWV), for assessing cardiovascular risk in young populations with no or elevated cardiovascular risk factors (CVRFs).
Materials And Methods: This study enrolled 180 young, apparently healthy individuals who underwent ufPWV measurements. They were classified into three groups: the CVRF-free group (n = 60), comprising current non-smokers with untreated blood pressure < 140/90 mmHg, fasting blood glucose (FBG) < 7.

Slippery liquid-infused porous surfaces (or "SLIPS") can prevent bacterial surface fouling, but they do not inherently possess the means to kill bacteria or reduce cell loads in surrounding media. Past reports show that the infused liquids in these materials can be leveraged to load and release antimicrobial agents, but these approaches are generally limited to the use of hydrophobic agents that are soluble in the infused oily phases. Here, we report the design of so-called "proto-SLIPS" that address this limitation and permit the release of highly water-soluble (or oil-insoluble) agents.

Ultraviolet B (UVB) radiation (280-320 nm) has been recognized as a carcinogen since 1928, leading to sun exposure minimization. However, epidemiological studies suggest that sun exposure correlates with increased life expectancy and reduced incidence of cardiovascular diseases and certain cancers such as colon and endometrial cancer. UVB exposure also influences liver metabolism, protects against hepatocellular lipotoxicity, and affects metabolic health.

Background: Digital media frequently contains positive portrayals of alcohol content, which has been shown to be associated with alcohol-related cognitions and behaviors. Because youth are heavy media consumers and have access to unsupervised, repeat viewing of media content on their personal mobile devices, it is critical to understand the frequency of encountering alcohol content in adolescents' daily lives and how adolescents engage with the content.
Objective: This paper outlines the study protocol for examining adolescents' exposure to alcohol-related content in digital media within their natural environments.
