The seasonality of respiratory diseases has been linked, among other factors, to low outdoor absolute humidity and low indoor relative humidity, which increase evaporation of water in the mucosal lining of the respiratory tract. We demonstrate that normal breathing results in an absorption-desorption cycle inside facemasks, in which supersaturated air is absorbed by the mask… Continue reading #Hydrating the respiratory tract: an alternative explanation why masks lower severity of #COVID-19

Quantifying asymptomatic infection and transmission of #COVID-19 in New York City using observed cases, serology, and testing capacity
The contributions of asymptomatic infections to herd immunity and community transmission are key to the resurgence and control of COVID-19, but are difficult to estimate using current models that ignore changes in testing capacity. Using a model that incorporates daily testing information fit to the case and serology data from New York City, we show… Continue reading Quantifying asymptomatic infection and transmission of #COVID-19 in New York City using observed cases, serology, and testing capacity
Post-traumatic stress disorder ( #PTSD ) in mid-age and older adults differs by immigrant status and ethnicity, #nutrition, and other determinants of health in the Canadian Longitudinal Study on Aging (CLSA)
This study aimed to address knowledge gaps about post-traumatic stress disorder (PTSD) in mid-age and older adults, with particular attention to the relationship of PTSD with nutrition and with ethnicity and immigrant status. Methods Binary logistic regression analysis of weighted comprehensive cohort data from the baseline Canadian Longitudinal Study on Aging (CLSA; n = 27,211) was conducted… Continue reading Post-traumatic stress disorder ( #PTSD ) in mid-age and older adults differs by immigrant status and ethnicity, #nutrition, and other determinants of health in the Canadian Longitudinal Study on Aging (CLSA)
A Little #Autonomy Support Goes a Long Way: Daily Autonomy‐Supportive Parenting, Child Well‐Being, Parental Need Fulfillment, and Change in Child, Family, and Parent Adjustment Across the Adaptation to the #COVID‐19 Pandemic
This study examined the effects of daily parental autonomy support on changes in child behavior, family environment, and parental well‐being across 3 weeks during the COVID‐19 pandemic in Germany. Day‐to‐day associations among autonomy‐supportive parenting, parental need fulfillment, and child well‐being were also assessed. Parents (longitudinal N = 469; Mage = 42.93, SDage = 6.40) of… Continue reading A Little #Autonomy Support Goes a Long Way: Daily Autonomy‐Supportive Parenting, Child Well‐Being, Parental Need Fulfillment, and Change in Child, Family, and Parent Adjustment Across the Adaptation to the #COVID‐19 Pandemic
Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study
To determine if accelerometer measured sedentary behavior (SED), light‐intensity physical activity (LPA), and moderate‐to‐vigorous–intensity physical activity (MVPA) in midlife is prospectively associated with cognitive function. Participants were 1970 adults enrolled in the CARDIA (Coronary Artery Risk Development in Young Adults) study who wore an accelerometer in 2005 to 2006 (ages 38–50 years) and had cognitive… Continue reading Longitudinal Associations of Midlife Accelerometer Determined #Sedentary Behavior and Physical Activity With #Cognitive Function: The CARDIA Study
Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia
Childhood overweight and obesity (OW/OB) is increasingly centered in low- and middle-income countries (LMICs) as rural populations experience market integration and lifeway change. Most explanatory studies have relied on imprecise estimates of children's energy expenditure, restricting understanding of the relative effects of changes in diet and energy expenditure on the development of OW/OB in transitioning… Continue reading Childhood Daily #Energy Expenditure Does Not Decrease with Market Integration and Is Not Related to #Adiposity in Amazonia
Recurrence of major #depressive disorder and its predictors in the general population: results from The Netherlands Mental Health Survey and Incidence Study (NEMESIS)
Knowledge of the risk of recurrence after recovery from major depressive disorder (MDD) in the general population is scarce. Method Data were derived from 687 subjects in the general population with a lifetime DSM-III-R diagnosis of MDD but without a current major depressive episode (MDE) or dysthymia. Participants had to be at least 6 months… Continue reading Recurrence of major #depressive disorder and its predictors in the general population: results from The Netherlands Mental Health Survey and Incidence Study (NEMESIS)
Progression of #Myopia in School-Aged Children After #COVID-19 Home Confinement
Time spent in outdoor activities has decreased owing to home confinement for the coronavirus disease 2019 (COVID-19) pandemic. Concerns have been raised about whether home confinement may have worsened the burden of myopia owing to substantially decreased time spent outdoors and increased screen time at home.. .. Of the 123 535 children included in the study,… Continue reading Progression of #Myopia in School-Aged Children After #COVID-19 Home Confinement
Evaluating the impact of a time orientation intervention on #well-being during the #COVID-19 lockdown: past, present or future?
Lockdown policies brought on by the COVID-19 pandemic pose a threat to well-being. This study examined the effectiveness of three positive psychology interventions, with different time-orientations, on well-being as well as predictors of well-being during lockdown. Participants (n= 216) completed measures of lockdown characteristics, attachment orientation, and emotion regulation, were then randomly allocated to one… Continue reading Evaluating the impact of a time orientation intervention on #well-being during the #COVID-19 lockdown: past, present or future?
