Expedited Recovery Pain Management Pathway for Minimally Invasive Repair of Pectus Excavatum (MIRPE)

Introduction: Pectus Excavatum (PEX) is the most common anterior chest wall deformity. While minimally invasive repair of pectus excavatum (MIRPE) has improved perioperative outcomes, there continue to be opportunities to optimize postoperative pain management and reduce length of stay (LOS). We compared the impact of a multimodal expedited protocol utilizing a combination of systemic and regional analgesia (with single shot paravertebral truncal blocks), along with coping techniques (such as meditation), and physical therapy, with systemic analgesia on LOS and opioid requirements. Methods: 51 patients underwent MIRPE with an expedited recovery protocol in comparison with 112 historical control patients at a single center over 18 years. LOS and opioid analgesic morphine milliequivalent (MME) were compared. Data were stratified for age, biological sex, and Haller index (HI) to identify potential confounding variables. Results: There was no difference in age or HI between cohorts. LOS was reduced by 59.1% in the enhanced recovery group compared to the historic group (1.8 days vs 4.4 days, SD=0.5664 and 0.9503 respectively, P\u3c 0.0001). On postoperative day (POD)1, the expedited patients required an average of 100.7 MME (IQR 61.65-124.3) compared to 123.6 MME (IQR 79.5-161.1) for historic control patients (P=0.04). Cumulative MME for POD0-2 was 34.8% less in the expedited recovery patients (P= Conclusions: This MIRPE expedited recovery pain protocol using a standardized multimodal analgesia strategy and regional anesthesia is a safe and effective therapeutic plan that results in decreased opioid analgesic requirements and a significantly decreased LOS

A survey of the global impact of COVID‐19 on the practice of pediatric anesthesia: A study from the pediatric anesthesia COVID‐19 Collaborative Group

BackgroundPediatric anesthesiology has been greatly impacted by COVID-19 in the delivery of care to patients and to the individual providers. With this study, we sought to survey pediatric centers and highlight the variations in care related to perioperative medicine during the COVID-19 pandemic, including the availability of protective equipment, the practice of pediatric anesthesia, and economic impact.AimThe aim of the survey was to determine how COVID-19 directly impacted pediatric anesthesia practices during the study period.MethodsA survey concerning four major domains (testing, safety, clinical management/policy, economics) was developed. It was pilot tested for clarity and content by members of the Pediatric Anesthesia COVID-19 Collaborative. The survey was administered by email to all Pediatric Anesthesia COVID-19 Collaborative members on September 1, 2020. Respondents had six weeks to complete the survey and were instructed to answer the questions based on their institution's practice during September 1 - October 13, 2020.ResultsSixty-three institutions (100% response rate) participated in the COVID-19 Pediatric Anesthesia Survey. Forty-one hospitals (65%) were from the United States, and 35% included other countries. N95 masks were available to anesthesia teams at 91% of institutions (n = 57) (95% CI: 80%-96%). COVID-19 testing criteria of anesthesia staff and guidelines to return to work varied by institution. Structured simulation training aimed at improving COVID-19 safety and patient care occurred at 62% of institutions (n = 39). Pediatric anesthesiologists were economically affected by a reduction in their employer benefits and restriction of travel due to employer imposed quarantine regulations.ConclusionOur data indicate that the COVID-19 pandemic has impacted the testing, safety, clinical management, and economics of pediatric anesthesia practice. Further investigation into the long-term consequences for the specialty is indicated

\u3ci\u3eDrosophila\u3c/i\u3e Muller F Elements Maintain a Distinct Set of Genomic Properties Over 40 Million Years of Evolution

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D. erecta, D. mojavensis, and D. grimshawi F elements and euchromatic domains from the Muller D element. We find that F elements have greater transposon density (25–50%) than euchromatic reference regions (3–11%). Among the F elements, D. grimshawi has the lowest transposon density (particularly DINE-1: 2% vs. 11–27%). F element genes have larger coding spans, more coding exons, larger introns, and lower codon bias. Comparison of the Effective Number of Codons with the Codon Adaptation Index shows that, in contrast to the other species, codon bias in D. grimshawi F element genes can be attributed primarily to selection instead of mutational biases, suggesting that density and types of transposons affect the degree of local heterochromatin formation. F element genes have lower estimated DNA melting temperatures than D element genes, potentially facilitating transcription through heterochromatin. Most F element genes (~90%) have remained on that element, but the F element has smaller syntenic blocks than genome averages (3.4–3.6 vs. 8.4–8.8 genes per block), indicating greater rates of inversion despite lower rates of recombination. Overall, the F element has maintained characteristics that are distinct from other autosomes in the Drosophila lineage, illuminating the constraints imposed by a heterochromatic milieu
