Large-scale and detailed analyses of activity in the United States (US) remain limited. In this work, we leveraged the comprehensive wearable, demographic, and survey data from the All of Us Research Program, the largest and most diverse population health study in the US to date, to apply and extend the previous global findings on activity inequality within the context of the US. We found that daily steps differed by sex at birth, age, body characteristics, geography, and built environment.

Background: Longitudinal digital health studies combine passively collected information from digital devices, such as commercial wearable devices, and actively contributed data, such as surveys, from participants. Although the use of smartphones and access to the internet supports the development of these studies, challenges exist in collecting representative data due to low adherence and retention. We aimed to identify key factors related to adherence and retention in digital health studies and develop a methodology to identify factors that are associated with and might affect study participant engagement.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder with profound global impact. While Genome-wide Association Studies (GWAS) have revealed genomic variants linked to AD, their translational impact has been limited due to challenges in interpreting the identified genetic associations. To address this challenge, we have devised a novel approach termed Transcription Factor-Wide Association Studies (TF-WAS).

Article Synopsis
  • Higher olefins (HO) are important chemicals used to make various products including plastics, lubricants, and detergents, and their developmental toxicity was studied for regulatory purposes.
  • Five specific HO were tested on pregnant Sprague-Dawley rats at different doses (0, 100, 300, and 1000 mg/kg bw/day) to assess their effects from Day 3 to Day 19 of gestation.
  • The studies found no significant maternal or fetal toxicity from HO, with a No-Observed-Adverse-Effect Level (NOAEL) of 1000 mg/kg bw/day, indicating safety for both mother and fetus at this dose.

Recovering nitrogen (N) from wastewater is a potential avenue to reduce reliance on energy-intensive synthetic nitrogen fixation via Haber-Bosch and subsequent treatment of N-laden wastewaters through nitrification-denitrification. However, many technical and economic factors hinder widespread application of N recovery, particularly low N concentrations in municipal wastewater, paucity of high-efficiency separations technologies compatible with biological treatment, and suitable products and markets for recovered N. In this perspective, we contextualize the challenges of N recovery today, propose integrated biological and physicochemical technologies to improve selective and tunable N recovery, and propose an expanded product portfolio for recovered N products beyond fertilizers.

Background: Following the onset of the COVID-19 pandemic, RSV infections deviated from a previously reliable epidemiologic pattern of presentation. To investigate whether this change in RSV seasonality resulted in a change in frequency and severity of RSV infections, this single center retrospective study compares demographic and hospital factors during RSV seasons before and after the onset of the COVID-19 pandemic.

Methods: Included were patients under age 5 years who tested positive for RSV only by RT-PCR in our pediatric emergency departments during the last three RSV seasons before the onset of the COVID-19 pandemic in spring 2020, as compared to the first three seasons after the pandemic started.
