lementation of a mobile application to target systems barriers associated with event reporting significantly increased event reporting by EM residents, improved EM resident attitudes about event reporting, and reduced the time required to submit an event, ultimately promoting a culture of safety.
The usage of asynchronous resources such as blogs and podcasts is pervasive in academic medicine, despite little understanding of their actual effect on learner knowledge acquisition. This study sought to examine the objective effect of a blog post on knowledge acquisition and application among junior faculty in emergency medicine (EM) via randomized controlled study.

All accredited EM residency programs in the United States and Canada were contacted to identify assistant and associate program directors and medical education fellows for recruitment into this study. Upon enrollment, participants were randomized as to whether they received access to a supplemental blog post prior to listening to a podcast episode. After listening to the podcast episode, all participants completed an assessment that included a test of knowledge application and knowledge acquisition; demographic information was also obtained.

Ultimately, 103 participants completed the study; the study closed for enrollment in July 2019. Data were nonnormally distributed and groups were compared using the Wilcoxon rank-sum test. There were no significant differences between the demographics of the two groups nor was there a significant difference in knowledge between the two groups.

The addition of a supplementary blog post did not increase junior faculty knowledge of a podcast episode.

Navigating the emergency department (ED) workflow in an efficient manner is an important skill every emergency physician or advanced provider must master. There is a paucity of research into ways to improve how efficiently an ED provider works amid these distractions. This study seeks to determine whether the addition of an hourly automated reminder for resident physicians to review their patient list improves throughput metrics.

This a double-blinded randomized controlled trial in which resident physicians at a single community ED were randomly assigned to two groups the intervention group, which received automated hourly notifications within the electronic medical record (EMR) to review their patient list for those whose workup is completed, and the control group, which received no notifications. We prospectively analyzed records for 25,255 encounters with 19,264 individual patients seen by 64 residents over the study period. Three-level mixed-effects regression models were used to examine whether notift reduce the ED-LOS, TAT-D, or TAT-A. However, the TAT-A was 20.00 minutes longer in the intervention group compared to the control group. It is unclear whether this represents an unintended effect of the automated reminders or is simply a spurious correlation.
Regional knowledge dissemination and information sharing is a challenge among physically divided groups of physicians. Many staff and resident physicians do not have easy access to share clinical and medical education and research information with each other in an academic setting. Our divisions of emergency medicine could benefit from a novel approach aimed at improving overall connection and collaborative engagement.

By harnessing the sociomateriality properties of podcasting, we could achieve the dual goals of better connecting our faculty as well as educating the audience on aspects of clinical practice and education that are especially relevant to our region. We sought to primarily draw on local expertise for content. We developed a standardized structure for our monthly releases, with each episode composed of a main faculty segment, a resident-focused segment, and a medical education segment. Accessibility to the podcast was maximized through its publication across multiple platforms and detailed infect on our stated goals.
Emerging evidence suggests that chest radiography (CXR) following central venous catheter (CVC) placement is unnecessary when point-of-care ultrasound (POCUS) is used to confirm catheter position and exclude pneumothorax. However, few providers have adopted this practice, and it is unknown what contributing factors may play a role in this lack of adoption, such as ultrasound experience. The objective of this study was to evaluate the diagnostic accuracy of POCUS to confirm CVC position and exclude a pneumothorax after brief education and training of nonexperts.

We performed a prospective cohort study in a single academic medical center to determine the diagnostic characteristics of a POCUS-guided CVC confirmation protocol after brief training performed by POCUS nonexperts. POCUS nonexperts (emergency medicine senior residents and critical care fellows) independently performed a POCUS-guided CVC confirmation protocol after a 30-minute didactic training. The primary outcome was the diagnostic accuracy of thtic accuracy, efficiency, and feasibility of POCUS-guided CVC position confirmation, but not exclusion of pneumothorax.
Thirty-minute training of POCUS in nonexperts demonstrates adequate diagnostic accuracy, efficiency, and feasibility of POCUS-guided CVC position confirmation, but not exclusion of pneumothorax.Epidemiological studies frequently use black carbon (BC) as a proxy for traffic-related air pollution (TRAP). However, wildfire smoke (WFS) represents an important source of BC not often considered when using BC as a proxy for TRAP. Here, we examined the potential for WFS to bias TRAP exposure assessments based on BC measurements. Weekly integrated BC samples were collected across the Denver, CO region from May to November 2018. We collected 609 filters during our sampling campaigns, 35% of which were WFS-impacted. For each filter we calculated an average BC concentration. We assessed three GIS-based indicators of TRAP for each sampling location annual average daily traffic within a 300 m buffer, the minimum distance to a highway, and the sum of the lengths of roadways within 300 m. Median BC concentrations were 9% higher for WFS-impacted filters (median = 1.14 μg/m3, IQR = 0.23 μg/m3) than nonimpacted filters (median = 1.04 μg/m3, IQR = 0.48 μg/m3). During WFS events, BC concentrations were elevated and expected spatial gradients in BC were reduced. Akt inhibitor We conducted a simulation study to estimate TRAP exposure misclassification as the result of regional WFS. Our results suggest that linear health effect estimates were biased away from the null when WFS was present. Thus, exposure assessments relying on BC as a proxy for TRAP may be biased by wildfire events. Alternative metrics that account for the influence of "brown" carbon associated with biomass burning may better isolate the effects of traffic emissions from those of other black carbon sources.Mood disorders represent a pressing public health issue and significant source of disability throughout the world. The classical monoamine hypothesis, while useful in developing improved understanding and clinical treatments, has not fully captured the complex nature underlying mood disorders. Despite these shortcomings, the monoamine hypothesis continues to dominate the conceptual framework when approaching mood disorders. However, recent advances in basic and clinical research have led to a greater appreciation for the role that amino acid neurotransmitters play in the pathophysiology of mood disorders and as potential targets for novel therapies. In this article we review progress of compounds that focus on these systems. We cover both glutamate-targeting drugs such as esketamine, AVP-786, REL-1017, AXS-05, rapastinel (GLYX-13), AV-101, NRX-101; as well as GABA-targeting drugs such as brexanolone (SAGE-547), ganaxolone, zuranolone (SAGE-217), and PRAX-114. We focus the review on phase-II and phase-III clinical trials and evaluate the extant data and progress of these compounds.[This corrects the article DOI 10.1021/acsomega.1c00732.].Strontium ruthenium oxide (SrRuO3) is recognized as a metallic itinerant ferromagnet and utilized as a conducting electrode in heterostructure oxides with unforeseen optical characteristics, including remarkably low-reflection and high-absorption visible-light spectrum compared to classical metals. By coupling mesoporous SrRuO3 nanoparticles (NPs) with porous g-C3N4 nanosheets for the first time, we evidence remarkably promoted visible light absorption and superior photocatalytic performances for Hg(II) reduction under illumination with visible light. The photocatalytic performance of g-C3N4 increased upon boosting the SrRuO3 percentage to 1.5%, and this (1.5% SrRuO3/g-C3N4 heterostructure) is considered the optimum condition to obtain a high photocatalytic efficiency of about 100% within 50 min. It was promoted 3.68 and 5.75 times compared to SrRuO3 and g-C3N4, respectively. Also, a Hg(II) reduction rate of 1.5% SrRuO3/g-C3N4 was enhanced3.84- and 6.28-fold than those of pure SrRuO3 NPs and g-C3N4, respectively. Such a high photocatalytic performance over SrRuO3/g-C3N4 photocatalysts was explained by the characteristics of SrRuO3 NPs incorporated on porous g-C3N4 layers, which demonstrate strong absorption of visible light with a narrow band gap, a large photocurrent density of ∼9.07 mA/cm2, well-dispersed and small particle sizes, and cause facile diffusion of HCOOH and Hg(II) ions and electrons. The present work provides a dramatic novel approach to the challenge of constructing visible-light photosensitive photocatalysts for wastewater remediation.In the actual environment, impurity atoms significantly affect the adsorption/dissociation of gas molecules on the substrate surface and in turn promote or impede the formation of subsequent products. In this study, we investigate the effects of three kinds of impurity atoms (H, O, and S) on the adsorption/dissociation of hydrogen sulfide (H2S) and hydrogen (H) diffusion processes by using the density functional theory method. We found that impurity atoms can change the charge density distribution of the surface and thus affect the adsorption/dissociation process of H2S. The existence of a H atom reduces the dissociation barrier of H2S. The adsorption site of H2S near the O atom is transferred from the bridge site to the adjacent top site and the first-order dissociation barrier of H2S is 0.07 eV, which is prominently lower than that of the pristine surface (0.28 eV). The presence of a S atom transfers the adsorption site of H2S to a farther bridge site and effectively affects the dissociation process of H2S. Both O and S atoms hinder the dissociation process of HS. Moreover, the diffusion process of H atoms to the subsurface can be slightly impeded by the O atom. Our work theoretically explains the influence mechanism of impurity atoms on the adsorption/dissociation of H2S and H diffusion behavior on the Fe(100) surface.A new class of actinide complexes [(L)An(NSiMe32)3] (An = Th or U) (Th1-Th3 and U1-U3) supported by highly nucleophilic seven-membered N-heterocyclic iminato ligands were synthesized and fully characterized by single-crystal X-ray diffraction. These complexes were successfully exploited as powerful catalysts for the addition of alcohols to carbodiimides to yield the corresponding desirable isourea products at room temperature with short reaction times and excellent yields. Thorough stoichiometric, thermodynamic, and kinetic studies were carried out, allowing us to propose a plausible mechanism for the catalytic reaction.
