Abstract

IntroductionDecision-making in emergencies is a multifactorial process based on the rescuer, patient, setting and resources. The eye-tracking system is a proven method for assessing decision-making process that has been used in different fields of science. Our aim was to evaluate the lifeguards' capacity to perform the ABCDE (Airway-Breathing-Circulation-Dissability-Exposure) approach when facing a simulated critically ill-drowned victim. MethodsA cross sectional simulation study was designed to assess the skills and sequence of the ABCDE approach by 20 professional lifeguards. They had to assess a victim and act according to his/her clinical status following the ABCDE primary assessment approach. Two kind of variables were recorder: those related to quality of each step of the ABCDE approach; visual behaviour using a portable eye-movement system. The eye-tracking system was the Mobile Eye system (Bedford, USA). ResultsNone of the study participants was able to complete correctly the ABCDE approach. Lifeguards spent more time in the Circulation step: Airway (15.5{+/-}11.1 s), Breathing (25.1{+/-}21.1 s), Circulation (44.6{+/-}29.5 s), Disability (38.5{+/-}0.7 s). Participants spent more time in viewpoints considered as important (65.5{+/-}17.4 s) compared with secondary ones (34.6{+/-}17.4 s, p = 0.008). This also was represented in the percentage of visual fixations (fixations in important viewpoints: 63.36{+/-}15.06; fixation in secondary viewpoints: 36.64{+/-}15.06). ConclusionProfessional lifeguards failed to fully perform the ABCDE sequence. Evaluation by experts with the help of eye-tracking technology detected lifeguards' limitations in the assessment and treatment of an eventual critically ill victim. Such deficits should be considered in the design and implementation of lifeguards training programmes.

Functional Assessment and Extended Culture of Human Pediatric Cardiac Tissue Slices for Preclinical Testing

Background: Living human myocardial slices preserve native tissue architecture, but their application to pediatric cardiac physiology or prolonged functional testing remains limited. We adapted a passive culture method for small surgical myocardial specimens obtained from patients with congenital heart disease (CHD). Methods: Atrial and ventricular specimens were obtained from 41 cardiac surgery patients (7.7{+/-}11.1 years; 1 day-49 years). Myocardial tissue was sectioned into slices and studied acutely, or maintained under free floating, rocking cell culture conditions without electrical or mechanical stimulation. Calcium transients were recorded in response to external pacing (0.2-2 Hz) at baseline, and after isoproterenol or norepinephrine exposure. Selected preparations underwent viability, histological, and gene expression analyses. Results: Pacing evoked calcium transients were recorded from all four cardiac chambers, exhibiting expected frequency-dependent shortening. Mean interslice and intraslice coefficients of variation were 11.1% and 7.6%. Viability was 85.8 {+/-} 5.6% post-slicing and 78.8 {+/-} 5.0% after 3-5 hours. Calcium transients remained detectable through 178 days in atrial and 119 days in ventricular slices. Calcium transient durations were relatively stable during extended culture. Beta-adrenergic agonists shortened calcium transient durations (isoproterenol: 32% atrial, 25% ventricular at 0.3 Hz); responses to isoproterenol persisted to approximately 120 days in selected atrial slices and 60 days in ventricular slices. Selected histological features were preserved, although some extracellular matrix and apoptosis related transcripts changed. Conclusions: Small surgical specimens support repeated physiological measurements and pharmacological testing during extended passive culture, providing a platform for human developmental and disease-specific cardiac research.

High latitude, high tolerance: Northern juvenile Chinook salmon exhibit substantial thermal plasticity and acute heat tolerance

In a rapidly warming North, Chinook salmon are facing rising river temperatures, increasing frequencies of heat waves, and greater annual thermal variation. These factors have putatively contributed to substantial declines in Alaska Chinook salmon abundance; understanding the thermal sensitivity and acclimation capacity of Chinook salmon at the northern extents of their range is therefore imperative. To this end, we acclimated juvenile Yukon River Chinook to five ecologically relevant summer temperatures (12.5, 15, 17.5, 20, and 22.5{degrees}C) under two feeding treatments of 100% or 40% satiation. We then assessed whole organism heat tolerance at rest and while swimming, along with the thermal sensitivity of heart rate and cardiac electrical activity. Yukon River Chinook substantially increased whole organism heat tolerance at rest and under exercise with warm acclimation. Cardiac heat tolerance also increased, and fish showed marked thermal compensation of maximum heart rate, resetting it to lower levels with warm acclimation. Feed treatment had a limited effect outside of peak heart rate and the transition temperatures of Q10. Warm acclimation was also associated with a shortening of the PR and QRS intervals and a lengthening of the QT interval. Across all acclimation groups, the PR interval plateaued to an extent far greater than heart rate itself, suggesting that limitations to AV conduction may limit cardiac function at high acute temperatures. Altogether, high latitude juvenile Chinook display remarkable heat tolerance and thermal plasticity, which may be preserved in association with the large seasonal, weather dependent, and spatial thermal variation Yukon River Chinook face during freshwater rearing and along with their extensive seaward and return migrations. The acute heat tolerance of Yukon River Chinook, which is comparable to or outperforming lower latitude Chinook and other salmonids, emphasizes the need for population-specific work for informed conservation efforts.

mTORC1-dependent control of Hedgehog signaling mediates nutrient-responsive licensing of intestinal stem cell differentiation

How progenitor cells couple their metabolic state to the regulation of fate and differentiation remains a fundamental question in tissue development and regeneration. Here, we identify a nutrient-responsive circuit that links progenitor anabolism to differentiation in the Drosophila midgut. We show that the mTORC1 downstream effector PWP1 is necessary and sufficient for differentiation of intestinal stem cell progeny toward the absorptive lineage in fed animals. In progenitors with high mTORC1 activity, PWP1 controls gene expression to promote Hedgehog (Hh) signaling, which cell autonomously drives progenitor differentiation into enterocytes. This circuit is constrained by feedback regulation, as elevated Hh activity inhibits mTORC1 and consequently excludes PWP1 from the nucleus. Disruption of the mTORC1-PWP1-Hh axis causes a progressive failure of enterocyte turnover during aging and reduced lifespan. While the aged midguts retain their barrier function, defective renewal leads to aging-associated deregulation of intestinal metabolism. Collectively, these observations support the concept of growth-dependent licensing of differentiation, whereby the nutrient-responsive anabolic state of a progenitor cell controls its lineage progression, consequently enabling organ renewal.
