AbstractAirborne microplastics (MPs) have been sampled globally, and their concentration is known to increase in areas of high human population and activity, especially indoors. Respiratory symptoms and disease following exposure to occupational levels of MPs within industry settings have also been reported. It remains to be seen whether MPs from the environment can be inhaled,… Continue reading Detection of microplastics in human lung tissue using μFTIR spectroscopy

The Impact of Face-Masks on Total Mortality Heterogenous Effects by Gender and Age
AbstractGovernments around the world have been implementing several non-pharmaceutical interventions (NPIs) to fight Covid-19 spread and its associated mortality. We estimate the causal impact of mandatory face-mask wearing policy in public places on (total) mortality in Switzerland. We exploit the staggered introduction of the policy across Swiss cantons using a Difference-in-Difference and an event study… Continue reading The Impact of Face-Masks on Total Mortality Heterogenous Effects by Gender and Age
Use of face masks did not impact COVID-19 incidence among 10–12-year-olds in Finland
AbstractIn fall 2021 in Finland, the recommendation to use face masks in schools for pupils ages 12 years and above was in place nationwide. Some cities recommended face masks for younger pupils as well. Our aim was to compare COVID-19 incidence among 10–12-year-olds between cities with different recommendations on the use of face masks in… Continue reading Use of face masks did not impact COVID-19 incidence among 10–12-year-olds in Finland
Current and future burdens of heat-related hyponatremia – a nationwide register-based study
ContextA seasonal variation in hyponatremia, with higher incidence rates during hot summer days has been demonstrated. Whether this applies to cool temperate regions is currently unknown. ObjectiveThe aim of this study was to investigate the influence of ambient temperature on hyponatremia in the Swedish population under current and future climate scenarios. Design, setting and patientsNationwide… Continue reading Current and future burdens of heat-related hyponatremia – a nationwide register-based study
Sex-specific effects of bisphenol A on the signaling pathway of ESRRG in the human placenta
AbstractBisphenol A (BPA) exposure during pregnancy is associated with low fetal weight, particularly in male fetuses. The expression of estrogen-related receptor gamma (ESRRG), a receptor for BPA in the human placenta, is reduced in fetal growth restriction. This study sought to explore whether ESRRG signaling mediates BPA-induced placental dysfunction and determine whether changes in the… Continue reading Sex-specific effects of bisphenol A on the signaling pathway of ESRRG in the human placenta
Light exposure during sleep impairs cardiometabolic function
SignificanceAmbient nighttime light exposure is implicated as a risk factor for adverse health outcomes, including cardiometabolic disease. However, the effects of nighttime light exposure during sleep on cardiometabolic outcomes and the related mechanisms are unclear. This laboratory study shows that, in healthy adults, one night of moderate (100 lx) light exposure during sleep increases nighttime… Continue reading Light exposure during sleep impairs cardiometabolic function
Saccade-related neural communication in the human medial temporal lobe is modulated by the social relevance of stimuli
Humans predominantly explore their environment by moving their eyes. To optimally communicate and process visual information, neural activity needs to be coordinated with the execution of eye movements. We investigated the coordination between visual exploration and interareal neural communication by analyzing local field potentials and single neuron activity in patients with epilepsy. We demonstrated that… Continue reading Saccade-related neural communication in the human medial temporal lobe is modulated by the social relevance of stimuli
The Foegen effect A mechanism by which facemasks contribute to the COVID-19 case fatality rate
Extensive evidence in the literature supports the mandatory use of facemasks to reduce the infection rate of severe acute respiratory syndrome coronavirus 2, which causes the coronavirus disease (COVID-19). However, the effect of mask use on the disease course remains controversial. This study aimed to determine whether mandatory mask use influenced the case fatality rate… Continue reading The Foegen effect A mechanism by which facemasks contribute to the COVID-19 case fatality rate
Unravelling the Role of the Mandatory Use of Face Covering Masks for the Control of SARS-CoV-2 in Schools: A Quasi-Experimental Study Nested in a Population-Based Cohort in Catalonia (Spain)
Background: Mandatory use of face covering masks (FCM) had been established for children aged six and above in Catalonia (Spain), as one of the non-pharmaceutical interventions aimed at mitigating SARS-CoV-2 transmission within schools. To date, the effectiveness of this mandate has not been well established. The quasi-experimental comparison between 5 year-old children, as a control… Continue reading Unravelling the Role of the Mandatory Use of Face Covering Masks for the Control of SARS-CoV-2 in Schools: A Quasi-Experimental Study Nested in a Population-Based Cohort in Catalonia (Spain)
