Journal ArticleDOI
Conformal piezoelectric energy harvesting and storage from motions of the heart, lung, and diaphragm
Canan Dagdeviren,Byung Duk Yang,Yewang Su,Yewang Su,Phat L. Tran,Pauline Joe,Eric K. Anderson,Jing Xia,Jing Xia,Vijay A. Doraiswamy,Behrooz Dehdashti,Xue Feng,Bingwei Lu,Robert S. Poston,Zain Khalpey,Roozbeh Ghaffari,Yonggang Huang,Marvin J. Slepian,John A. Rogers +18 more
TL;DR: Advanced materials and devices are reported that enable high-efficiency mechanical-to-electrical energy conversion from the natural contractile and relaxation motions of the heart, lung, and diaphragm, demonstrated in several different animal models, each of which has organs with sizes that approach human scales.
Journal ArticleDOI

Abbas Rana,Angelika C. Gruessner,Vatche G. Agopian,Zain Khalpey,Irbaz Bin Riaz,Bruce Kaplan,Karim J. Halazun,Ronald W. Busuttil,Rainer W.G. Gruessner +8 more
TL;DR: It is demonstrated that more than 2 million life-years were saved to date by solid-organ transplants during a 25-year study period.
Journal ArticleDOI
Relationship of perioperative hyperglycemia and postoperative infections in patients who undergo general and vascular surgery.
Margarita S. Ramos,Zain Khalpey,Stuart R. Lipsitz,Jill Steinberg,Maria T. Panizales,Michael J. Zinner,Selwyn O. Rogers +6 more
TL;DR: The increased risk of POI and length of hospitalization posed by postoperative hyperglycemia is independent of diabetic status and needs further evaluation to assess for possible benefits of postoperative glycemic control in patients who have undergone general surgery.
Journal ArticleDOI
Venoarterial Extracorporeal Membrane Oxygenation for Cardiogenic Shock and Cardiac Arrest
TL;DR: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) as discussed by the authors is a form of temporary mechanical circulatory support and simultaneous extrorporeal gas exchange and is a salvage intervention in patients with cardiogenic shock, even cardiac arrest refractory to standard therapies.
Journal ArticleDOI
Prevalence and Variability of Internal Mammary Artery Graft Use in Contemporary Multivessel Coronary Artery Bypass Graft Surgery. Analysis of the Society of Thoracic Surgeons National Cardiac Database
Minoru Tabata,Joshua D. Grab,Zain Khalpey,Fred H. Edwards,Sean M. O'Brien,Lawrence H. Cohn,R. Morton Bolman +6 more
TL;DR: Frequency of IMA use in coronary artery bypass graft surgery is increasing; however, many patients still do not receive the benefits of I MA grafts, and some hospitals have a very low Ima use rate.
