Pain management in adult patients with sickle cell disease in the emergency department: how does current practice compare with existing standards of care?

Purpose: Sickle cell disease (SCD) is an inherited blood disorder with a natural course punctuated by acute complications including painful vaso-occlusive episodes. The objectives were: (1) to determine what proportion of patients with SCD receive opioids within 30 min of triage as recommended by the current clinical recommendations and quality standard; and (2) to identify facilitators to timely opioid administration for patients with SCD.

Methods: This was a retrospective observational study.

Anti-seizure medication treatment trials prior to pre-surgical evaluation.

Purpose: Our study evaluates patterns of anti-seizure medication (ASM) usage prior to pre-surgical evaluation in drug resistant epilepsy (DRE).

Methods: We conducted a retrospective study of patients with DRE presenting for pre-surgical evaluation from 1/1/2017 to 12/31/2018. We abstracted demographic data, ASM usage, MRI and EEG findings, and distance from home to our center.

A meta-analysis of experienced incivility and its correlates: Exploring the dual path model of experienced workplace incivility.

The present study proposes and examines a theoretical Dual Path Model of Experienced Workplace Incivility using meta-analytic relationships (k = 246; N = 145, 008) between experienced incivility and frequent correlates. The stress-induced mechanism was supported with perceived stress mediating the meta-analytical relationship between experienced incivility and occupational health (i.e.

Larger neural responses produce BOLD signals that begin earlier in time.

Functional MRI analyses commonly rely on the assumption that the temporal dynamics of hemodynamic response functions (HRFs) are independent of the amplitude of the neural signals that give rise to them. The validity of this assumption is particularly important for techniques that use fMRI to resolve sub-second timing distinctions between responses, in order to make inferences about the ordering of neural processes. Whether or not the detailed shape of the HRF is independent of neural response amplitude remains an open question, however.

Object recognition in clutter: cortical responses depend on the type of learning.

Theoretical studies suggest that the visual system uses prior knowledge of visual objects to recognize them in visual clutter, and posit that the strategies for recognizing objects in clutter may differ depending on whether or not the object was learned in clutter to begin with. We tested this hypothesis using functional magnetic resonance imaging (fMRI) of human subjects. We trained subjects to recognize naturalistic, yet novel objects in strong or weak clutter.

Contrast Response Functions for Single Gabor Patches: ROI-Based Analysis Over-Represents Low-Contrast Patches for GE BOLD.

IMPORTANT FOR THE INTERPRETATION OF BOLD FMRI DATA IS A LINEAR RELATIONSHIP BETWEEN THE BOLD RESPONSE AND THE UNDERLYING NEURAL ACTIVITY: increased BOLD responses should reflect proportionate increases in the underlying neural activity. While previous studies have demonstrated a linear relationship between the peak amplitude of the BOLD response and neural activity in primary visual cortex (V1), these studies have used stimuli that excite large areas of cortex, and the linearity of the BOLD response has not been demonstrated when only a small patch of cortex is stimulated. The BOLD response to isolated Gabor patches of increasing contrast was measured with gradient echo (GE) BOLD and spin echo (SE) BOLD at 7 T.
