Quality of Resuscitative Care Provided to an Infant with Abusive Head Trauma in Community Emergency Departments: An In Situ, Prospective Simulation-Based Study
Objectives
Abusive head trauma (AHT) is a very common and serious form of physical abuse, and a major cause of mortality and morbidity for young children. Early Recognition and supportive care of children with AHT is a common challenge in community emergency department (CEDs). We hypothesized that standardized, in situ simulation can be used to measure and compare the quality of resuscitative measures provided to children with AHT in a diverse set of CEDs.
Methods
This prospective, simulation-based study measured teams' performance across CEDs. The primary outcome was overall adherence to AHT using a 15-item performance assessment checklist based on the number of tasks performed correctly on the checklist.
Results
Fifty-three multiprofessional teams from 18 CEDs participated in the study. Of 270 participants, 20.7% were physicians, 65.2% registered nurses, and 14.1% were other providers. Out of all tasks, assessment of airway/breathing was the most successfully conducted task by 53/53 teams (100%). Although 43/53 teams (81%) verbalized the suspicion for AHT, only 21 (39.6%) of 53 teams used hyperosmolar agent, 4 (7.5%) of 53 teams applied cervical spine collar stabilization, and 6 (11.3%) of 53 teams raised the head of the bed. No significant difference in adherence to the checklist was found in the CEDs with an inpatient pediatric service or these with designated adult trauma centers compared with CEDs without. Community emergency departments closer to the main academic center outperformed CEDs these that are further away.
Conclusions
This study used in situ simulation to describe quality of resuscitative care provided to an infant presenting with AHT across a diverse set of CEDs, revealing variability in the initial recognition and stabilizing efforts and provided and targets for improvement. Future interventions focusing on reducing these gaps could improve the performance of CED providers and lead to improved patient outcomes
Preparedness for Pediatric Office Emergencies: A Multicenter, Simulation-Based Study
OBJECTIVES
Pediatric emergencies can occur in pediatric primary care offices. However, few studies have measured emergency preparedness, or the processes of emergency care, provided in the pediatric office setting. In this study, we aimed to measure emergency preparedness and care in a national cohort of pediatric offices.
METHODS
This was a multicenter study conducted over 15 months. Emergency preparedness scores were calculated as a percentage adherence to 2 checklists on the basis of the American Academy of Pediatrics guidelines (essential equipment and supplies and policies and protocols checklists). To measure the quality of emergency care, we recruited office teams for simulation sessions consisting of 2 patients: a child with respiratory distress and a child with a seizure. An unweighted percentage of adherence to checklists for each case was calculated.
RESULTS
Forty-eight teams from 42 offices across 9 states participated. The mean emergency preparedness score was 74.7% (SD: 12.9). The mean essential equipment and supplies subscore was 82.2% (SD: 15.1), and the mean policies and protocols subscore was 57.1% (SD: 25.6). Multivariable analyses revealed that independent practices and smaller total staff size were associated with lower preparedness. The median asthma case performance score was 63.6% (interquartile range: 43.2–81.2), whereas the median seizure case score was 69.2% (interquartile range: 46.2–80.8). Offices that had a standardized process of contacting emergency medical services (EMS) had a higher rate of activating EMS during the simulations.
CONCLUSIONS
Pediatric office preparedness remains suboptimal in a multicenter cohort, especially in smaller, independent practices. Academic and community partnerships using simulation can help address gaps and implement important processes like contacting EMS
Mammal responses to global changes in human activity vary by trophic group and landscape
Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less active in undeveloped areas but unexpectedly more active in developed areas while exhibiting greater nocturnality. Carnivores were most sensitive, showing the strongest decreases in activity and greatest increases in nocturnality. Wildlife managers must consider how habituation and uneven sensitivity across species may cause fundamental differences in human–wildlife interactions along gradients of human influence.Peer reviewe
Finishing the euchromatic sequence of the human genome
The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf
We present the optical spectroscopic evolution of SN 2023ixf seen in subnight cadence spectra from 1.18 to 15 days after explosion. We identify high-ionization emission features, signatures of interaction with material surrounding the progenitor star, that fade over the first 7 days, with rapid evolution between spectra observed within the same night. We compare the emission lines present and their relative strength to those of other supernovae with early interaction, finding a close match to SN 2020pni and SN 2017ahn in the first spectrum and SN 2014G at later epochs. To physically interpret our observations, we compare them to CMFGEN models with confined, dense circumstellar material around a red supergiant (RSG) progenitor from the literature. We find that very few models reproduce the blended N iii ( λλ 4634.0,4640.6)/C iii ( λλ 4647.5,4650.0) emission lines observed in the first few spectra and their rapid disappearance thereafter, making this a unique diagnostic. From the best models, we find a mass-loss rate of 10 ^−3 –10 ^−2 M _⊙ yr ^−1 , which far exceeds the mass-loss rate for any steady wind, especially for an RSG in the initial mass range of the detected progenitor. These mass-loss rates are, however, similar to rates inferred for other supernovae with early circumstellar interaction. Using the phase when the narrow emission features disappear, we calculate an outer dense radius of circumstellar material R _CSM,out ≈ 5 × 10 ^14 cm, and a mean circumstellar material density of ρ = 5.6 × 10 ^−14 g cm ^−3 . This is consistent with the lower limit on the outer radius of the circumstellar material we calculate from the peak H α emission flux, R _CSM,out ≳ 9 × 10 ^13 cm
