Risk of COVID-19 Disease, Dialysis Unit Attributes, and Infection Control Strategy among London In-Center Hemodialysis Patients.

Background And Objectives: Patients receiving in-center hemodialysis treatment face unique challenges during the coronavirus disease 2019 (COVID-19) pandemic, specifically the need to attend for treatment that prevents self-isolation. Dialysis unit attributes and isolation strategies that might reduce dialysis center COVID-19 infection rates have not been previously examined.

Design, Setting, Participants, & Measurements: We explored the role of variables, including community disease burden, dialysis unit attributes (size and layout), and infection control strategies, on rates of COVID-19 among patients receiving in-center hemodialysis in London, United Kingdom, between March 2, 2020 and May 31, 2020.

Implementing neuroimaging and eye tracking methods to assess neurocognitive development of young infants in low- and middle-income countries.

Infants and children in low- and middle-income countries (LMICs) are frequently exposed to a range of environmental risk factors which may negatively affect their neurocognitive development. The mechanisms by which factors such as undernutrition and poverty impact development and cognitive outcomes in early childhood are poorly understood. This lack of knowledge is due in part to a paucity of objective assessment tools which can be implemented across different cultural settings and in very young infants.

Intranasal oxytocin decreases cross-frequency coupling of neural oscillations at rest.

Recent research has suggested a role for the hormone oxytocin in social cognition and behavior. Administration of intranasal oxytocin modulates multiple brain regions during experimental tasks; however, the neural mechanisms that underscore the changes associated with oxytocin administration are yet to be fully elucidated. In a double-blind placebo controlled design using electroencephalography, the effects of intranasal oxytocin on neural oscillations (delta, theta, alpha, beta) and their coupling during the resting state were examined.

Intranasal oxytocin and the neural correlates of infant face processing in non-parent women.

Event-related potentials (ERPs) have been widely employed to identify different stages of face processing, with recent research probing the neural dynamics of adult's processing of infant faces. Infant faces represent a salient category of visual stimuli, especially in parents, likely prioritized for processing through activity of the oxytocinergic system. Here we employed a randomized, double-blind, and within-subject crossover study of 24 non-parent women to examine the impact of intranasal oxytocin administration, relative to placebo, on processing infant and adult faces.

Ab initio calculation of the cross sections for electron impact vibrational excitation of CO via the (2)Π shape resonance.

The stabilization method is used to calculate the complex potential energy curve of the (2)Π state of CO(-) as a function of bond length, with the refinement that separate potentials are determined for p-wave and d-wave attachment and detachment of the excess electron. Using the resulting complex potentials, absolute vibrational excitation cross sections are calculated as a function of electron energy and scattering angle. The calculated cross sections agree well with experiment.
