Carr Z, Brenes-Bastos A, Longley M, Zafar J, Charchaflieh J. Rapid Submaximal Cardiopulmonary Exercise Testing in Older Adults Undergoing Noncardiac Surgery: Workflow Integration, Acceptability, and Physiologic Characterization in an Expanded Cohort. 2026, 1: e0016. DOI: 10.1097/ao9.0000000000000016.Peer-Reviewed Original ResearchReducing Systematic Overestimation Bias in the Duke Activity Status Index Estimated Peak Oxygen Uptake: A Cross-Sectional Analysis Using Submaximal Cardiopulmonary Exercise Testing
Hollingsworth K, Zhao Y, Charchaflieh J, Carr Z. Reducing Systematic Overestimation Bias in the Duke Activity Status Index Estimated Peak Oxygen Uptake: A Cross-Sectional Analysis Using Submaximal Cardiopulmonary Exercise Testing. A&A Practice 2026, 20: e02160. PMID: 41729842, DOI: 10.1213/xaa.0000000000002160.Peer-Reviewed Original ResearchThis study addresses the systematic overestimation of peak oxygen uptake by the Duke Activity Status Index (DASI) by validating a new, adjusted formula. By integrating BMI, age, and sex into the formula, the authors reduced bias.Does a Research Paper Always Need a Hypothesis?

Carr Z, Agarkov D, Li J, Charchaflieh J, Brenes-Bastos A, Freund J, Zafar J, Schonberger R, Heerdt P. Implementation of Brief Submaximal Cardiopulmonary Testing in a High-Volume Presurgical Evaluation Clinic: Feasibility Cohort Study. JMIR Perioperative Medicine 2025, 8: e65805. PMID: 39773953, PMCID: PMC11888076, DOI: 10.2196/65805.Peer-Reviewed Original ResearchThis study investigates the feasibility of implementing brief submaximal cardiopulmonary testing in high-volume presurgical clinics, showing it efficiently identifies lower functional capacity compared to traditional surveys in under 20 minutes.
