Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

A Copernican Approach to Brain Advancement: The Paradigm of Allostatic Orchestration
The objective of this presentation is to explore historical, scientific, interventional, and other differences between the two paradigms, so that innovators, researchers, practitioners, policy-makers, patients, end-users, and others can gain clarity with respect to both the explicit and implicit assumptions associated with brain advancement agendas of any kind. Over the course of three decades, a series of brain-centric, evolution-inspired insights have been articulated with increasing refinement, as principles of allostasis (Sterling and Eyer, 1988; Sterling, 2004, 2012, 2014). Allostasis recognizes that the role of the ...

Association of Long-Term Exposure to Transportation Noise and Traffic-Related Air Pollution with the Incidence of Diabetes: A Prospective Cohort Study
Conclusion: We found a positive association between residential transportation noise and diabetes, adding to the growing body of evidence that noise pollution exposure may be independently linked to metabolic health and should be considered when developing public health interventions. https://doi.org/10.1289/EHP1279 Received: 26 October 2016 Revised: 07 May 2017 Accepted: 09 May 2017 Published: 31 August 2017 Address correspondence to C.

Association between Exposure to p,p ′-DDT and Its Metabolite p,p′-DDE with Obesity: Integrated Systematic Review and Meta-Analysis
Conclusions: We classified p,p′-DDT and p,p′-DDE as “presumed” to be obesogenic for humans, based on a moderate level of primary human evidence, a moderate level of primary in vivo evidence, and a moderate level of supporting evidence from in vivo and in vitro studies. https://doi.org/10.1289/EHP527 Received: 17 May 2016 Revised: 04 May 2017 Accepted: 09 May 2017 Published: 18 September 2017 Please address correspondence to M.A. La Merrill, Dept. of Environmental Toxicology, University of California, Davis, 1 Shields Ave., 4245 Meyer Hall, Davis, CA 95616-5270 USA.

Using wearable devices in clinical trials
Brandy Chittester, chief of clinical operations, IMARC Globally, more than 325 million people own wearable, connected devices, and more than 2.5 billion own smartphones. Using wearable devices in clinical trials can bring huge benefits, however, there are also concerns. Here’s a look at how researchers are using wearable devices — and what you should consider before using them in your own research. How wearable devices are advancing medicine Right now, ClinicalTrials.gov, a global database of clinical trials, lists nearly 200 trials with “wearable devices” or “wearable technology” in the description. This in...

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...
