It is unclear to what extent the duration of screen time in infancy is associated with the subsequent diagnosis of autism spectrum disorder. Objective To examine the association between screen time in infancy and the development of autism spectrum disorder at 3 years of age. Design, Setting, and Participants This cohort study analyzed data from… Continue reading Association Between Screen Time Exposure in Children at 1 Year of Age and Autism Spectrum Disorder at 3 Years of AgeThe Japan Environment and Children’s Study

SARS-CoV-2 reinfections: Overview of efficacy and duration of natural and hybrid immunity
Highlights•A previous SARS-CoV-2 infection is associated with a significantly reduced risk of reinfections with efficacy lasting for at least one year and only relatively moderate waning immunity. •Natural immunity shows roughly similar effect sizes regarding protection against reinfection across different SARS-CoV-2 variants, with the exception of the Omicron variant for which data are just emerging… Continue reading SARS-CoV-2 reinfections: Overview of efficacy and duration of natural and hybrid immunity
The influence of bright and dim light on substrate metabolism, energy expenditure and thermoregulation in insulin-resistant individuals depends on time of day
Aims/hypothesisIn our modern society, artificial light is available around the clock and most people expose themselves to electrical light and light-emissive screens during the dark period of the natural light/dark cycle. Such suboptimal lighting conditions have been associated with adverse metabolic effects, and redesigning indoor lighting conditions to mimic the natural light/dark cycle more closely… Continue reading The influence of bright and dim light on substrate metabolism, energy expenditure and thermoregulation in insulin-resistant individuals depends on time of day
Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
BackgroundTogether with poor biodegradability and insufficient recycling, the massive production and use of plastics have led to widespread environmental contamination by nano- and microplastics. These particles accumulate across ecosystems - even in the most remote habitats - and are transferred through food chains, leading to inevitable human ingestion, that adds to the highest one due… Continue reading Immunotoxicity and intestinal effects of nano- and microplastics: a review of the literature
Non-target screening for the identification of migrating compounds from reusable plastic bottles into drinking water
Highlights•Migration of > 400 plastic related and > 3500 dishwasher related compounds. •The dishwashing process increased the migration of plastic related compounds. •Oligomers suspected from polycaprolactone (PCL) were migrating. •Three of the identified photoinitiators have possible endocrine disrupting effects. •Diethyltoluamide (DEET) may have been formed from the plasticizer laurolactam. AbstractReusable plastic sports bottles are used… Continue reading Non-target screening for the identification of migrating compounds from reusable plastic bottles into drinking water
School closure and management practices during coronavirus outbreaks including COVID-19: a rapid systematic review
In response to the coronavirus disease 2019 (COVID-19) pandemic, 107 countries had implemented national school closures by March 18, 2020. It is unknown whether school measures are effective in coronavirus outbreaks (eg, due to severe acute respiratory syndrome [SARS], Middle East respiratory syndrome, or COVID-19). We undertook a systematic review by searching three electronic databases… Continue reading School closure and management practices during coronavirus outbreaks including COVID-19: a rapid systematic review
Adolescent psychiatric disorders during the COVID-19 pandemic and lockdown
Highlights•The COVID-19 pandemic and lockdown may have a negative impact on the mental health of adolescents. •Epidemics and disasters are associated with adolescent Post Traumatic Stress, Depression, and Anxiety symptoms. •Healthcare system adaptations are necessary for mental health support despite the lockdown. •Home confinement may be associated with increased intrafamilial violence. •Data is scarce on… Continue reading Adolescent psychiatric disorders during the COVID-19 pandemic and lockdown
Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study
Late-life exposure to ambient air pollution is a modifiable risk factor for dementia, but epidemiological studies have shown inconsistent evidence for cognitive decline. Air quality (AQ) improvement has been associated with improved cardiopulmonary health and decreased mortality, but to the best of our knowledge, no studies have examined the association with cognitive function. We examined… Continue reading Air quality improvement and cognitive decline in community-dwelling older women in the United States: A longitudinal cohort study
Adipogenic Activity of Chemicals Used in Plastic Consumer Products
Bisphenols and phthalates, chemicals frequently used in plastic products, promote obesity in cell and animal models. However, these well-known metabolism-disrupting chemicals (MDCs) represent only a minute fraction of all compounds found in plastics. To gain a comprehensive understanding of plastics as a source of exposure to MDCs, we characterized the chemicals present in 34 everyday… Continue reading Adipogenic Activity of Chemicals Used in Plastic Consumer Products
