RESUMO

OBJECTIVES: The objective of this study was to determine the association of the use of extracorporeal cardiopulmonary resuscitation (ECPR) with survival to hospital discharge in pediatric patients with a noncardiac illness category. A secondary objective was to report on trends in ECPR usage in this population for 20 years. DESIGN: Retrospective multicenter cohort study. SETTING: Hospitals contributing data to the American Heart Association's Get With The Guidelines-Resuscitation registry between 2000 and 2021. PATIENTS: Children (<18 yr) with noncardiac illness category who received greater than or equal to 30 minutes of cardiopulmonary resuscitation (CPR) for in-hospital cardiac arrest. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Propensity score weighting balanced ECPR and conventional CPR (CCPR) groups on hospital and patient characteristics. Multivariable logistic regression incorporating these scores tested the association of ECPR with survival to discharge. A Bayesian logistic regression model estimated the probability of a positive effect from ECPR. A secondary analysis explored temporal trends in ECPR utilization. Of 875 patients, 159 received ECPR and 716 received CCPR. The median age was 1.0 [interquartile range: 0.2-7.0] year. Most patients (597/875; 68%) had a primary diagnosis of respiratory insufficiency. Median CPR duration was 45 [35-63] minutes. ECPR use increased over time ( p < 0.001). We did not identify differences in survival to discharge between the ECPR group (21.4%) and the CCPR group (16.2%) in univariable analysis ( p = 0.13) or propensity-weighted multivariable logistic regression (adjusted odds ratio 1.42 [95% CI, 0.84-2.40; p = 0.19]). The Bayesian model estimated an 85.1% posterior probability of a positive effect of ECPR on survival to discharge. CONCLUSIONS: ECPR usage increased substantially for the last 20 years. We failed to identify a significant association between ECPR and survival to hospital discharge, although a post hoc Bayesian analysis suggested a survival benefit (85% posterior probability).

RESUMO

AIM: To evaluate pediatric cardiopulmonary resuscitation (CPR) quality during intra-hospital transport to facilitate extracorporeal membrane oxygenation (ECMO)-CPR (ECPR). We compared chest compression (CC) rate, depth, and fraction (CCF) between the pre-transport and intra-transport periods. METHODS: Observational study of children <18 years with either in-hospital cardiac arrest (IHCA) or out-of-hospital cardiac arrest (OHCA) who underwent transport between two care locations within the hospital for ECPR and who had CPR mechanics data available. Descriptive patient and arrest characteristics were summarized. The primary analysis compared pre- to intra-transport CC rate, depth, and fraction. A secondary analysis compared the proportion of pre- versus intra-transport 60-s epochs meeting guideline recommendations for rate (100-120/min), depth (≥4 cm for infants; ≥5 cm for children ≥1 year), and CCF (≥0.80). RESULTS: Seven patients (four IHCA; three witnessed OHCA) met eligibility criteria. Six (86%) patients survived the event and two (28%) survived to hospital discharge. Median transport CPR duration was 7 [IQR 5.5, 8.5] minutes. There were no differences in pre- vs. intra-transport CC rate (115 [113, 118] vs. 118 [114, 127] CCs/minute; p = 0.18), depth (3.2 [2.7, 4.4] vs. 3.6 [2.5, 4.6] cm; p = 0.50), or CCF (0.89 [0.82, 0.90] vs. 0.92 [0.79, 0.97]; p = 0.31). Equivalent proportions of 60-s CPR epochs met guideline recommendations between pre- and intra-transport (rate: 66% vs. 57% [p = 0.22]; depth: 14% vs. 19% [p = 0.39]; CCF: 80% vs. 75% [p = 0.43]). CONCLUSIONS: Pediatric CPR quality was maintained during intra-hospital patient transport, suggesting that it is reasonable for ECPR systems to incorporate patient transport to facilitate ECMO cannulation.

RESUMO

Students presenting with varying degrees of respiratory symptoms and distress occur commonly in the school setting. It is important to develop a differential diagnosis for respiratory distress, to initiate stabilization of the student with life-threatening symptoms, and to triage these students to an appropriate level of care (back to the classroom, home with their guardian with follow up at their primary health care provider's office, or directly to the closest emergency department via Emergency Medical Services). This article describes the initial assessment and management of a student presenting with respiratory distress.

RESUMO

Chemotherapy is the main treatment for patients with breast cancer metastases, but natural alternatives have been receiving attention for their potential as novel anti-tumor reagents. Amplexicaule A (APA) is a flavonoid glucoside isolated from rhizomes of Polygonum amplexicaule D. Don var. sinense Forb (PADF). We found that APA has anti-tumor effects in a breast cancer xenograft mouse model and induces apoptosis in breast cancer cell lines. APA increased levels of cleaved caspase-3,-8,-9 and PARP, which resulted from suppression of MCL-1 and BCL-2 expression in the cells. APA also inactivated the Akt/mTOR pathway in breast cancer cells. Thus, APA exerts a strong anti-tumor effect on breast cancer cells, most likely through induction of apoptosis. Our study is the first to identify this novel anti-tumor compound and provides a new strategy for isolation and separation of single compounds from herbs.
