A national pilot study on simulation-based upstander training for emergency medicine clinicians.

Objective: This study assesses the effectiveness of clinical simulation-based training in boosting self-perceived confidence for using upstander communication skills to confront racism, discrimination, and microaggressions (RDM).

Methods: We conducted an observational cohort study with emergency medicine professionals at the 2023 Scientific Assembly of the American Academy of Emergency Medicine in New Orleans, Louisiana. The study featured a clinical simulation-based training on upstander communications skills session followed by small- and large-group debriefs.

Long-Term Mortality Predictors Using a Machine-Learning Approach in Patients With Chronic Limb-Threatening Ischemia After Peripheral Vascular Intervention.

Background: Patients with chronic limb-threatening ischemia (CLTI) face a high long-term mortality risk. Identifying novel mortality predictors and risk profiles would enable individual health care plan design and improved survival. We aimed to leverage a random survival forest machine-learning algorithm to identify long-term all-cause mortality predictors in patients with CLTI undergoing peripheral vascular intervention.

Long-range electrostatic effects from intramolecular Lewis acid binding influence the redox properties of cobalt-porphyrin complexes.

A Co-porphyrin complex (1) with an appended aza-crown ether for Lewis acid (LA) binding was synthesized and characterized. NMR spectroscopy and electrochemistry show that cationic group I and II LAs (, Li, Na, K, Ca, Sr, and Ba) bind to the aza-crown ether group of 1. The binding constant for Li is comparable to that observed for a free aza-crown ether.

Racial Disparities in Blood Pressure at Time of Acute Ischemic Stroke Presentation: A Population Study.

Background: Hypertension is a stroke risk factor with known disparities in prevalence and management between Black and White patients. We sought to identify if racial differences in presenting blood pressure (BP) during acute ischemic stroke exist.

Methods And Results: Adults with acute ischemic stroke presenting to an emergency department within 24 hours of last known normal during study epochs 2005, 2010, and 2015 within the Greater Cincinnati/Northern Kentucky Stroke Study were included.

Prevalence and predictors of workplace violence against nurses in Africa: A systematic review and meta-analysis.

Background And Aims: Workplace violence (WPV) against nurses is a pervasive global issue, yet the extent of this phenomenon in the African context remains insufficiently explored. This review aimed to synthesize the available literature to identify the prevalence and predictors of WPV against nurses in Africa.

Methods: A systematic search was conducted across MEDLINE, CINAHL, PsycINFO, and Scopus, to identify studies published from 2000 to October 2023.

Emotional State Transitions in Trauma-Exposed Individuals With and Without Posttraumatic Stress Disorder.

Importance: Posttraumatic stress disorder (PTSD) is marked by the contrasting symptoms of hyperemotional reactivity and emotional numbing (ie, reduced emotional reactivity). Comprehending the mechanism that governs the transition between neutral and negative emotional states is crucial for developing targeted therapeutic strategies.

Objectives: To explore whether individuals with PTSD experience a more pronounced shift between neutral and negative emotional states and how the intensity of emotional numbing symptoms impacts this shift.

An updated infrageneric classification of the pantropical species-rich genus L. (Clusiaceae) and some insights into the systematics of New Caledonian species, based on molecular and morphological evidence.

L. is a pantropically distributed genus comprised of at least 250 species of shrubs and trees and has centers of diversity located in Africa/Madagascar, Australasia, and Southeast Asia. The genus is notable due to its extreme diversity of floral form, common presence in lowland tropical rainforests worldwide, and potential pharmacological value.

Switching the proton-coupled electron transfer mechanism for non-canonical tyrosine residues in a protein.

The proton-coupled electron transfer (PCET) reactions of tyrosine (Y) are instrumental to many redox reactions in nature. This study investigates how the local environment and the thermodynamic properties of Y influence its PCET characteristics. Herein, 2- and 4-mercaptophenol (MP) are placed in the well-folded αC protein (forming 2MP-αC and 4MP-αC) and oxidized by external light-generated [Ru(L)] complexes.

Factors related to willingness to participate in biomedical research on neglected tropical diseases: A systematic review.

Background: Understanding the barriers to and facilitators of participation in research could enhance recruitment rates for biomedical research on Neglected Tropical Diseases (NTDs) and help to avoid the problems associated with poor recruitment.

Methodology/principal Findings: We conducted a systematic review to identify factors related to willingness to participate in biomedical research on Neglected Tropical Diseases (NTDs). Our search included the following databases: Medline/PubMed, Embase (Embase.

Iron(iv) alkyl complexes: electronic structure contributions to Fe-C bond homolysis and migration reactions that form N-C bonds from N.

High-valent iron alkyl complexes are rare, as they are prone to Fe-C bond homolysis. Here, we describe an unusual way to access formally iron(iv) alkyl complexes through double silylation of iron(i) alkyl dinitrogen complexes to form an NNSi group. Spectroscopically validated computations show that the disilylehydrazido(2-) ligand stabilizes the formal iron(iv) oxidation state through a strongly covalent Fe-N π-interaction, in which one π-bond fits an "inverted field" description.

Asymptomatic Intracerebral Hemorrhage Following Endovascular Stroke Therapy Is Not Benign: A Systematic Review and Meta-Analysis.

Background: Asymptomatic intracerebral hemorrhage (aICH) occurs in approximately 35% of patients with acute ischemic stroke after endovascular thrombectomy. Unlike symptomatic ICH, studies evaluating the effect of aICH on outcomes have been inconclusive. We performed a systematic review and meta-analysis to evaluate the long-term effects of postendovascular thrombectomy aICH.

Understanding clerkship experiences in emergency medicine and their potential influence on specialty selection: A qualitative study.

Objectives: The specialty of emergency medicine (EM) is experiencing a significant decrease in student interest. In addition, women are historically underrepresented within the specialty at all levels of training and practice. We sought to understand how clinical experiences and perceptions of EM influence specialty selection by medical students, particularly women.

Support vector machine prediction of individual Autism Diagnostic Observation Schedule (ADOS) scores based on neural responses during live eye-to-eye contact.

Social difficulties during interactions with others are central to autism spectrum disorder (ASD). Understanding the links between these social difficulties and their underlying neural processes is a primary aim focused on improved diagnosis and treatment. In keeping with this goal, we have developed a multivariate classification method based on neural data acquired by functional near infrared spectroscopy, fNIRS, during live eye-to-eye contact with adults who were either typically developed (TD) or individuals with ASD.

Association of Periodic Limb Movements and Obstructive Sleep Apnea With Risk of Cardiovascular Disease and Mortality.

Background: Obstructive sleep apnea is a well-established risk factor for cardiovascular disease (CVD). Recent studies have also linked periodic limb movements during sleep to CVD. We aimed to determine whether periodic limb movements during sleep and obstructive sleep apnea are independent or synergistic factors for CVD events or death.

Bulky, electron-rich, renewable: analogues of Beller's phosphine for cross-couplings.

In recent years, considerable progress has been made in the conversion of biomass into renewable chemicals, yet the range of value-added products that can be formed from biomass remains relatively small. Herein, we demonstrate that molecules available from biomass serve as viable starting materials for the synthesis of phosphine ligands, which can be used in homogeneous catalysis. Specifically, we prepared renewable analogues of Beller's ligand (di(1-adamantyl)--butylphosphine, cataCXium® A), which is widely used in homogeneous catalysis.
