The cerebellum influences motor control through Purkinje target neurons, which transmit cerebellar output. Such output is required, for instance, for larval zebrafish to learn conditioned fictive swimming. The output cells, called eurydendroid neurons (ENs) in teleost fish, are inhibited by Purkinje cells and excited by parallel fibers. Here, we investigated the electrophysiological properties of glutamatergic ENs labeled by the transcription factor olig2. Action potential firing and synaptic responses were recorded in current clamp and voltage clamp from olig2⁺ neurons in immobilized larval zebrafish (before sexual differentiation) and were correlated with motor behavior by simultaneous recording of fictive swimming. In the absence of swimming, olig2⁺ ENs had basal firing rates near 8 spikes/s, and EPSCs and IPSCs were evident. Comparing Purkinje firing rates and eurydendroid IPSC rates indicated that 1-3 Purkinje cells converge onto each EN. Optogenetically suppressing Purkinje simple spikes, while preserving complex spikes, suggested that eurydendroid IPSC size depended on presynaptic spike duration rather than amplitude. During swimming, EPSC and IPSC rates increased. Total excitatory and inhibitory currents during sensory-evoked swimming were both more than double those during spontaneous swimming. During both spontaneous and sensory-evoked swimming, the total inhibitory current was more than threefold larger than the excitatory current. Firing rates of ENs nevertheless increased, suggesting that the relative timing of IPSCs and EPSCs may permit excitation to drive additional eurydendroid spikes. The data indicate that olig2⁺ cells are ENs whose activity is modulated with locomotion, suiting them to participate in sensorimotor integration associated with cerebellum-dependent learning.

SIGNIFICANCE STATEMENT The cerebellum contributes to movements through signals generated by cerebellar output neurons, called eurydendroid neurons (ENs) in fish (cerebellar nuclei in mammals). ENs receive sensory and motor signals from excitatory parallel fibers and inhibitory Purkinje cells. Here, we report electrophysiological recordings from ENs of larval zebrafish that directly illustrate how synaptic inhibition and excitation are integrated by cerebellar output neurons in association with motor behavior. The results demonstrate that inhibitory and excitatory drive both increase during fictive swimming, but inhibition greatly exceeds excitation. Firing rates nevertheless increase, providing evidence that synaptic integration promotes cerebellar output during locomotion. The data offer a basis for comparing aspects of cerebellar coding that are conserved and that diverge across vertebrates.

Of the 58 people who have died due to COVID-19 in Windsor-Essex, 14 of them were patients at Windsor Regional Hospital's field hospital.

Skills learned in standardized courses are estimated to last only a few months. Neonatal Resuscitation Program certification is mandatory for all pediatric residents and is valid for 2 years. Exact timing of when proficiency is lost is unknown.

Neonatal Resuscitation Program skills deteriorate immediately after certification, whereas knowledge is better retained. Significant skill deficits were seen at baseline raising concerns regarding the efficacy of the current course structure. Discrepancies in knowledge and skill retention may impact caregiver performance. (Read the full article)

Heart rate continues to be the single most important indicator of well-being in a newborn. Availability of a reliable method to determine heart rate in the first minute would help determine resuscitation interventions, particularly for the extremely premature infant.

Electrocardiograms can provide a reliable, continuous heart rate in the most premature infants in the first minute of resuscitation compared with pulse oximeters. (Read the full article)

Rapid initiation of effective chest compressions (CCs) for patients in cardiac arrest improves outcomes, yet even trained rescuers fail to provide consistently effective CCs. Pediatric data on CC quality and objective measures of CC work are limited.

CC quality deteriorates similarly in pediatric and adult models, and overall work done to compress the pediatric chest is similar to that in adults. Power output during CC performance is analogous to that generated during intense exercise such as running. (Read the full article)

Excess tissue oxygenation should be avoided during neonatal resuscitation, especially in premature infants. Delivered oxygen concentrations when using a self-inflating bag (SIB) at oxygen flows <1 L/min remain to be established.

Low oxygen concentrations (30%– 40%) can be delivered with a SIB at an oxygen flow <1 L/min. A practical scheme has been developed correlating the oxygen flow rate and the corresponding delivered fraction of oxygen when using a neonatal SIB. (Read the full article)

Preterm infants can be successfully resuscitated with <100% oxygen (O₂); however, initiation with room air remains controversial. Current Neonatal Resuscitation Program (NRP) guidelines suggest using air or blended O₂ to titrate O₂ to meet target preductal saturation goals.

This is the first trial to compare a limited O₂ strategy to target NRP–recommended transitional goal saturations versus a high O₂ strategy in preterm infants. The limited O₂ strategy decreased integrated excess oxygen and oxidative stress and improved respiratory outcomes. (Read the full article)

Pulse oximeter is better than skin color assessment in the initial minutes of life. After sensor application, a delay occurs in the display of reliable saturation and heart rate. An appropriate method of sensor placement can minimize the delay.

Attaching sensor first to oximeter and then to neonate picked up signal faster than attaching it to the neonate first and then to the equipment. However, the time from birth to display of reliable signal was similar between the methods. (Read the full article)

High-fidelity simulation improves individual skills in neonatal resuscitation. Usually, training is performed in a simulation center. Little is known about the impact of in situ training on overall team performance.

In situ high-fidelity simulation training of 80% of a maternity’s staff significantly improved overall team performance in neonatal resuscitation (technical skills and teamwork). Fewer hazardous events occurred, and delay in improving the heart rate was shorter. (Read the full article)

Infants who require positive pressure ventilation at birth are considered to be at risk for subsequent compromise and are recommended to receive postresuscitation care. The supportive evidence and details of this care have not been fully investigated.

We investigate the need for postresuscitation care in infants who require positive pressure ventilation at birth, review the aspects of care needed, and explore the important risk factors most predictive of it. (Read the full article)

The frequency of cardiac arrest is significantly lower in children than in adults, rendering the delivery of high-quality cardiopulmonary resuscitation more difficult. Metronome-based studies in adults showed improvement in adequate compression rate, with a detrimental effect on the depth of chest compressions.

This is the first pediatric study to confirm that the use of a metronome during cardiopulmonary resuscitation significantly improves the delivery of adequate rate without affecting the compression depth. This effect was more prominent among medical students and pediatric residents and fellows than nurses. (Read the full article)

PMC is happy to announce the addition of a citation exporter feature. This feature makes it easy to retrieve either styled citations that you can copy/paste into your manuscripts, or to download them into a format compatible with your bibliographic reference manager software.

When viewing an Entrez search results page, each result summary will now include a "Citation" link. When, clicked, this will open a pop-up window that you can use to easily copy/paste citations formatted in one of three popular styles: AMA (American Medical Association), MLA (Modern Language Association), or APA (American Psychological Association). In addition, the box has links at the bottom that can be used to download the citation information in one of three machine-readable formats, which most bibliographic reference management software can import.

The same citation box can also be invoked from an individual article, either in classic view (with the "Citation" link among the list of formats) or the PubReader view, by clicking on the citation information just below the article title in the banner.

These human-readable styled citations, and machine-readable formats, will be available through a public API, and we will be providing more details about that in another announcement, on the pmc-utils-announce mailing list. Please subscribe to that list if you are interested.

Actin polymerization is a crucial process during sperm capacitation. We have recently described the participation of FAK during actin polymerization in guinea pig spermatozoa. However, the mechanism by which FAK mediates these processes is unknown. Our previous data have shown that MAPK1 (hereafter referred to as ERK2) is activated during the first minutes of capacitation, and inhibition of ERK2 blocked actin polymerization and the acrosome reaction. In this current study, we found that FAK is involved in ERK2 activation – as FAK was phosphorylated at tyrosine residue 925 and bound to Grb2 – and that inhibition of FAK results in a significant decrease of ERK2 activation. We also confirmed the presence of Rho guanine nucleotide exchange factor 2 (ARHGEF2, hereafter referred to as GEF-H1), which is able to associate with RhoA during capacitation. RhoA activation and its participation in actin polymerization were also analyzed. Inhibition of FAK or ERK1/2 impeded GEF-H1 phosphorylation, RhoA activation, and the association between GEF-H1 and RhoA. Finally, we observed the presence of fibronectin on the sperm surface, its role in sperm–sperm interaction as well as participation of β-integrin in the activation of ERK2. Our results show that the signaling pathway downstream of fibronectin, via integrin, FAK, Grb2, MEK1/2, ERK2, GEF-H1 and RhoA regulates the actin polymerization associated with spermatozoa capacitation.

When managing septic shock, passive leg raising is the best test to determine if a patient is likely to respond to a fluid bolus, better than CVP lines or even bedside ultrasound. Dr Najib Ayas, Associate professor of Critical Care Medicine at the University of British Columbia, discusses shock management from the context of his Rational Clinical examination article in the September 27, 2016 issue of JAMA, entitled “Will This Hemodynamically Unstable Patient Respond to a Bolus of Intravenous Fluids?”
