A Systematic Review of Epileptiform Changes During Sevoflurane Anesthesia In Infants and Children

OBJECTIVES/GOALS: Early clinical case reports have described incidental epileptiform changes during electrophysiological monitoring. The objective of this study was to perform a systematic review of all existing investigations of epileptiform activity during sevoflurane use in pediatric anesthesia. The heterogenous EEG data will be analyzed in a meta analysis METHODS/STUDY POPULATION: A targeted, PICO-based clinical question was crafted and registered a priori on PROSPERO on 3/19/21. Under the guidance of a librarian from the Albert Einstein College of Medicine, a boolean search string was generated to search articles and gray literature for terms such as pediatric, sevoflurane and electroencephalogram in PubMed, OVID, Cochrane, Google Scholar, etc. We utilized the software platform tool COVIDENCE to manage our review. 495 references were imported for initial screening. 56 English-language, full-text studies were included for further review. The final 13 references were included in data extraction and Newcastle-Ottawa bias assessment. The characteristics of the studies and their primary outcomes were collected in tabular form. Strategies for data synthesis were discussed weekly. RESULTS/ANTICIPATED RESULTS: Epileptiform changes reported in the literature during pediatric sevoflurane anesthesia ranged from 0 - 95%. EEG data were acquired using a variety of recording systems with variable number of leads and heterogeneous outcomes reported. The periods of anesthesia monitoring were also heterogeneous. Characteristics of the studies are presented in Table 1. 495 references were imported for screening with 13 final references for data extraction. EEG abnormalities were reported in 204/649 (31.4%) subjects ranging in age from neonate to 18 years;the majority of studies utilized less than 16 channels of (10/13, 76.9%) (Table 1). There was variability in sevoflurane dosing, premedication (e.g., midzolam, hydroxyzine), and periods of anesthesia monitored. DISCUSSION/SIGNIFICANCE: There was heterogeneity noted across reviewed literature including study design, phases of anesthesia, ventilation methods, number of EEG leads recorded and adjuvant anesthetics administered. Nevertheless, this review rigorously classified epileptiform activity during Sevoflurane thereby influencing modern anesthesia.

Factors Associated With Hospitalization in Children and Adolescents With SARS-CoV-2 Infection.

In this retrospective study of 319 children with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, we assessed whether age, asthma, obesity, diabetes, and socioeconomic status were associated with hospitalization for coronavirus disease 2019 (COVID-19). Demographic and clinical characteristics were assessed using univariate statistics, excluding incidental or unrelated positives. There was a bimodal distribution of age among hospitalized children. Obesity (P < .001) and a past medical history of diabetes (P = .001) were significantly more prevalent in hospitalized children, including cases of new-onset diabetes and diabetic ketoacidosis. Neither a past medical history of asthma nor lower socioeconomic status was associated with hospitalization. Although limited to a single center, the findings in this study may have important clinical implications. Targeted, proactive health outreach to children with obesity and diabetes, with prioritization of preventative efforts such as vaccination, may be important in preventing worse SARS-CoV-2 infection in this vulnerable group.

Prioritizing the Interview in Selecting Resident Applicants: Behavioral Interviews to Determine Goodness of Fit.

From our initial screening of applications, we assess that the 10% to 15% of applicants whom we will interview are all academically qualified to complete our residency training program. This initial screening to select applicants to interview includes a personality assessment provided by the personal statement, Dean's letter, and letters of recommendation that, taken together, begin our evaluation of the applicant's cultural fit for our program. While the numerical scoring ranks applicants preinterview, the final ranking into best fit categories is determined solely on the interview day at a consensus conference by faculty and residents. We analyzed data of 819 applicants from 2005 to 2017. Most candidates were US medical graduates (62.5%) with 23.7% international medical graduates, 11.7% Doctors of Osteopathic Medicine (DO), and 2.1% Caribbean medical graduates. Given that personality assessment began with application review, there was excellent correlation between the preinterview composite score and the final categorical ranking in all 4 categories. For most comparisons, higher scores and categorical rankings were associated with applicants subsequently working in academia versus private practice. We found no problem in using our 3-step process employing virtual interviews during the COVID pandemic.

Rehabilitation and In-Hospital Mortality in COVID-19 Patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) guidelines endorse early rehabilitation to improve outcomes in hospitalized patients, but the evidence base to support this recommendation is lacking. We examined the association between early rehabilitation and in-hospital deaths in COVID-19 patients. METHOD: A single-center retrospective study, involving 990 COVID-19 patients (42.4% women, mean age 67.8 years) admitted between March 1, 2020 and May 31, 2020 to a community hospital, was conducted. Association of rehabilitation during hospitalization with in-hospital mortality was examined using logistic regression analysis adjusted for demographics, length of stay, body mass index, comorbid illnesses, functional status as well as for COVID-19 presentations, treatments, and complications. RESULTS: Over the 3-month study period, 475 (48.0%) inpatients were referred for rehabilitation. Patients who received rehabilitation were older (73.7 ± 14.0 vs 62.3 ± 17.2). There were 61 hospital deaths (12.8%) in the rehabilitation group and 165 (32.0%) in the nonrehabilitation group. Receiving rehabilitation was associated with an 89% lower in-hospital mortality (odds ratio [OR]: 0.11, 95% confidence interval [CI]: 0.06-0.19) after adjusting for multiple confounders and COVID-19 disease markers. In sensitivity analyses, the results were significant in subpopulations defined by age group, sex, race, length of hospitalization, or pulmonary presentations. Each additional rehabilitation session was associated with a 29% lower risk of in-hospital mortality (OR per session: 0.71, 95% CI: 0.64-0.79) in the fully adjusted model. CONCLUSION: Among hospitalized COVID-19 patients, receiving early rehabilitation was associated with lower in-hospital mortality. Our findings support implementation of rehabilitation services for COVID-19 patients in acute care settings, but further research from randomized clinical trials is needed.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Qualitative Immunoglobulin G Assays: The Value of Numeric Reporting.

CONTEXT.­: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) testing is used for serosurveillance and will be important to evaluate vaccination status. Given the urgency to release coronavirus disease 2019 (COVID-19) serology tests, most manufacturers have developed qualitative tests. OBJECTIVE.­: To evaluate clinical performance of 6 different SARS-CoV-2 IgG assays and their quantitative results to better elucidate the clinical role of serology testing in COVID-19. DESIGN.­: Six SARS-CoV-2 IgG assays were tested using remnant specimens from 190 patients. Sensitivity and specificity were evaluated for each assay with the current manufacturer's cutoff and a lower cutoff. A numeric result analysis and discrepancy analysis were performed. RESULTS.­: Specificity was higher than 93% for all assays, and sensitivity was higher than 80% for all assays (≥7 days post-polymerase chain reaction testing). Inpatients with more severe disease had higher numeric values compared with health care workers with mild or moderate disease. Several discrepant serology results were those just below the manufacturers' cutoff. CONCLUSIONS.­: Severe acute respiratory syndrome coronavirus 2 IgG antibody testing can aid in the diagnosis of COVID-19, especially with negative polymerase chain reaction. Quantitative COVID-19 IgG results are important to better understand the immunologic response and disease course of this novel virus and to assess immunity as part of future vaccination programs.

Correlation of Coagulation Parameters With Clinical Outcomes During the Coronavirus-19 Surge in New York: Observational Cohort.

IMPORTANCE: COVID-19 has caused a worldwide illness and New York became the epicenter of COVID-19 in the United States from Mid-March to May 2020. OBJECTIVE: To investigate the coagulopathic presentation of COVID and its natural course during the early stages of the COVID-19 surge in New York. To investigate whether hematologic and coagulation parameters can be used to assess illness severity and death. DESIGN: Retrospective case study of positive COVID inpatients between March 20, 2020-March 31, 2020. SETTING: Montefiore Health System main hospital, Moses, a large tertiary care center in the Bronx. PARTICIPANTS: Adult inpatients with positive COVID tests hospitalized at MHS. EXPOSURE FOR OBSERVATIONAL STUDIES: Datasets of participants were queried for demographic (age, sex, socioeconomic status, and self-reported race and/or ethnicity), clinical and laboratory data. MAIN OUTCOME AND MEASURES: Relationship and predictive value of measured parameters to mortality and illness severity. RESULTS: Of the 225 in this case review, 75 died during hospitalization while 150 were discharged home. Only the admission PT, absolute neutrophil count (ANC) and first D-Dimer could significantly differentiate those who were discharged alive and those who died. Logistic regression analysis shows increased odds ratio for mortality by first D-Dimer within 48 hrs. of admission. The optimal cut-point for the initial D-Dimer to predict mortality was found to be 2.1 µg/mL. 15% of discharged patients required readmission and more than a third of readmitted patients died (5% of all initially discharged). CONCLUSION: We describe here a comprehensive assessment of hematologic and coagulation parameters in COVID-19 and examine the relationship of these to mortality. We demonstrate that both initial and maximum D-Dimer values are biomarkers that can be used for survival assessments. Furthermore, D-Dimer may be useful to follow up discharged patients.

Anticoagulation in COVID-19: Effect of Enoxaparin, Heparin, and Apixaban on Mortality.

BACKGROUND: Mortality in coronavirus disease of 2019 (COVID-19) is associated with increases in prothrombotic parameters, particularly D-dimer levels. Anticoagulation has been proposed as therapy to decrease mortality, often adjusted for illness severity. OBJECTIVE: We wanted to investigate whether anticoagulation improves survival in COVID-19 and if this improvement in survival is associated with disease severity. METHODS: This is a cohort study simulating an intention-to-treat clinical trial, by analyzing the effect on mortality of anticoagulation therapy chosen in the first 48 hours of hospitalization. We analyzed 3,625 COVID-19+ inpatients, controlling for age, gender, glomerular filtration rate, oxygen saturation, ventilation requirement, intensive care unit admission, and time period, all determined during the first 48 hours. RESULTS: Adjusted logistic regression analyses demonstrated a significant decrease in mortality with prophylactic use of apixaban (odds ratio [OR] 0.46, p = 0.001) and enoxaparin (OR = 0.49, p = 0.001). Therapeutic apixaban was also associated with decreased mortality (OR 0.57, p = 0.006) but was not more beneficial than prophylactic use when analyzed over the entire cohort or within D-dimer stratified categories. Higher D-dimer levels were associated with increased mortality (p < 0.0001). When adjusted for these same comorbidities within D-dimer strata, patients with D-dimer levels < 1 µg/mL did not appear to benefit from anticoagulation while patients with D-dimer levels > 10 µg/mL derived the most benefit. There was no increase in transfusion requirement with any of the anticoagulants used. CONCLUSION: We conclude that COVID-19+ patients with moderate or severe illness benefit from anticoagulation and that apixaban has similar efficacy to enoxaparin in decreasing mortality in this disease.
