Objectives: Research on the correlates of screen time in young children, that could be targeted in future interventions to improve healthy development, has primarily focused on TV viewing with little consideration of mobile devices. The objectives of this study were to examine the associations between a range of demographic, parental, and home environment correlates and preschool-aged children's TV/video viewing, video/computer game playing, and total screen time across traditional and mobile devices.
Methods: The results of this cross-sectional study are based on 106 preschool-aged children (3-5 years) and their parents recruited in 2018 in Edmonton, Alberta. Children's and parental demographic information, home characteristics, and information about parental and children's screen time use was measured using a parent questionnaire. Simple and multiple linear regression models were conducted.
Results: Each additional hour/day of parental screen time was associated with 12 (95%CI = 5.2, 19.8) minutes/day of children's TV/video, 6 (95%CI = 1.5, 11.0), minutes/day of video/computer game playing, and 19 (95%CI = 8.9, 29.2) minutes/day of total screen time. Additionally, significant associations of technology interference and presence of electronics in the bedroom with children's screen time were attenuated in the multiple regression models.
Conclusions: Parental screen time appears important to target in future family-based screen time interventions and initiatives. Future studies should explore potential mediating or moderating variables between parental screen time and children's screen time.

Are breast cancer patients with low distress at diagnosis at risk of psychological symptoms later in their disease trajectory? Considerations for when to screen for distress.

Introduction: To target psychological support to cancer patients most in need of support, screening for psychological distress has been advocated and, in some settings, also implemented. Still, no prior studies have examined the appropriate 'dosage' and whether screening for distress before cancer treatment may be sufficient or if further screenings during treatment are necessary. We examined the development in symptom trajectories for breast cancer patients with low distress before surgery and explored potential risk factors for developing burdensome symptoms at a later point in time.

Background: Developing interventions along with the population of interest using systems thinking is a promising method to address the underlying system dynamics of overweight. The purpose of this study is twofold: to gain insight into the perspectives of adolescents regarding: (1) the system dynamics of energy balance-related behaviours (EBRBs) (physical activity, screen use, sleep behaviour and dietary behaviour); and (2) underlying mechanisms and overarching drivers of unhealthy EBRBs.
Methods: We conducted Participatory Action Research (PAR) to map the system dynamics of EBRBs together with adolescents aged 10-14 years old living in a lower socioeconomic, ethnically diverse neighbourhood in Amsterdam East, the Netherlands.
Protocol for a systematic review and individual participant data meta-analysis for risk factors for lung cancer in individuals with lung nodules identified by low-dose CT screening.

Background: Worldwide, lung cancer (LC) is the second most frequent cancer and the leading cause of cancer related mortality. Low-dose CT (LDCT) screening reduced LC mortality by 20-24% in randomised trials of high-risk populations. A significant proportion of those screened have nodules detected that are found to be benign.

The foremost cause of dementia is Alzheimer's disease (AD). The vital pathological hallmarks of AD are amyloid beta (Aβ) peptide and hyperphosphorylated tau (p-tau) protein. The current animal models used in AD research do not precisely replicate disease pathophysiology, making it difficult for researchers to quickly and effectively gather data or screen potential therapy possibilities.

Sulfate and sulfonate compounds are extensively used as anionic surfactants in personal care products (PCPs), which might pose adverse potential to human health. However, available research mostly identified certain subsets of sulfated and sulfonated surfactants based on target analysis. In this study, we developed a comprehensive nontarget strategy for identification of sulfated and sulfonated surfactants in PCPs using UHPLCHRMS supplemented by an in-lab R script based on characteristic fragment ions and sulfur isotope patterns.
