Manual Uterine Aspiration Simulation for Emergency Medicine Learners.

Introduction: Manual uterine aspiration is a potentially lifesaving procedure for treating patients with hemorrhagic complications of early pregnancy loss. While early pregnancy loss is a common diagnosis seen in the emergency department, manual uterine aspiration education is lacking for emergency medicine physicians.

Methods: We designed a 90-minute procedural skills training session for 30 emergency medicine learners.

Scheduling practices for pregnant emergency medicine residents.

Background: Night shift work is associated with adverse pathophysiologic effects on maternal and fetal well-being. Although emergency medicine (EM) residents work frequent night shifts, there is no existing guidance for residency program directors (PDs) regarding scheduling pregnant residents. Our study assessed scheduling practices for pregnant EM residents, differences based on program and PD characteristics, barriers and attitudes toward implementing a formal scheduling policy, and PDs' awareness of literature describing adverse effects of night shifts on maternal-fetal outcomes.

Hand Therapy Regimen for Functional Recovery Following Combined Face and Bilateral Hand Transplantation.

Intensive postoperative rehabilitation therapy is associated with positive functional recovery in hand transplants (HTs). Our goal is to share the hand therapy protocol developed for our patient who underwent a combined face and bilateral HT. The patient is a 23-year-old right-hand-dominant male with a history of third-degree burns to 80% of his body following a motor vehicle accident.

Generational 'othering': The myth of the Millennial learner.

Context: The health professions education (HPE) literature is replete with recommendations for how educators should adapt practices to the needs of generations of learners using generation theory to bridge perceived differences between learners and educators. Yet the evidence supporting the application of generation theory in HPE has not been critically examined. If unsubstantiated, these applications may perpetuate biases towards learners they are intended to support.

Development and Empirical Testing of a Novel Team Leadership Assessment Measure: A Pilot Study Using Simulated and Live Patient Encounters.

Background: Team leadership is critical to health care resuscitation team performance. There has been increased focus on competency in team leadership behaviors; however, there is still variability in how team leadership is assessed within emergency medicine. The objective of this study was to develop and pilot a novel team leadership assessment measure for emergency medicine resuscitation teams.

Detecting rare asymmetrically methylated cytosines and decoding methylation patterns in the honeybee genome.

Context-dependent gene expression in eukaryotes is controlled by several mechanisms including cytosine methylation that primarily occurs in the CG dinucleotides (CpGs). However, less frequent non-CpG asymmetric methylation has been found in various cell types, such as mammalian neurons, and recent results suggest that these sites can repress transcription independently of CpG contexts. In addition, an emerging view is that CpG hemimethylation may arise not only from deregulation of cellular processes but also be a standard feature of the methylome.

Differential expression of melanopsin isoforms Opn4L and Opn4S during postnatal development of the mouse retina.

Photosensitive retinal ganglion cells (pRGCs) respond to light from birth and represent the earliest known light detection system to develop in the mouse retina. A number of morphologically and functionally distinct subtypes of pRGCs have been described in the adult retina, and have been linked to different physiological roles. We have previously identified two distinct isoforms of mouse melanopsin, Opn4L and Opn4S, which are generated by alternate splicing of the Opn4 locus.

Protein-tyrosine phosphatase 1B expression is induced by inflammation in vivo.

Protein-tyrosine phosphatase 1B (PTP1B) is a major negative regulator of insulin and leptin sensitivity. PTP1B overexpression in adipose tissue and skeletal muscle of humans and rodents may contribute to insulin resistance and obesity. The mechanisms mediating PTP1B overexpression in obese and diabetic states have been unclear.

Macrophage migration inhibitory factor governs endothelial cell sensitivity to LPS-induced apoptosis.

Human endothelial cells (EC) are typically resistant to the apoptotic effects of stimuli associated with lung disease. The determinants of this resistance remain incompletely understood. Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine produced by human pulmonary artery EC (HPAEC).

Effect of NADPH oxidase inhibition on cardiopulmonary bypass-induced lung injury.

Cardiopulmonary bypass (CPB) causes acute lung injury. Reactive oxygen species (ROS) from NADPH oxidase may contribute to this injury. To determine the role of NADPH oxidase, we pretreated pigs with structurally dissimilar NADPH oxidase inhibitors.

Effect of cGMP on lung microvascular endothelial barrier dysfunction following hydrogen peroxide.

The authors determined the effect of cyclic guanosine 3',5'-monophosphate (cGMP) on hydrogen peroxide (H(2)O(2))-induced barrier dysfunction in bovine lung microvascular endothelial cell (BLMVEC) monolayers and compared the results to bovine pulmonary artery endothelial cells (BPAECs). In BLMVECs, H(2)O(2) (250 microM) caused a 31.9% +/- 4.

Effect of bronchial artery blood flow on cardiopulmonary bypass-induced lung injury.

Cardiovascular surgery requiring cardiopulmonary bypass (CPB) is frequently complicated by postoperative lung injury. Bronchial artery (BA) blood flow has been hypothesized to attenuate this injury. The purpose of the present study was to determine the effect of BA blood flow on CPB-induced lung injury in anesthetized pigs.

Inhibition of inwardly rectifying K(+) channels by cGMP in pulmonary vascular endothelial cells.

Endothelial barrier dysfunction is typically triggered by increased intracellular Ca(2+) concentration. Membrane-permeable analogs of guanosine 3',5'-cyclic monophosphate (cGMP) prevent disruption of endothelial cell integrity. Because membrane potential (E(m)), which influences the electrochemical gradient for Ca(2+) influx, is regulated by K(+) channels, we investigated the effect of 8-bromo-cGMP on E(m) and inwardly rectifying K(+) (K(IR)) currents in bovine pulmonary artery and microvascular endothelial cells (BPAEC and BMVEC), using whole cell patch-clamp techniques.
