Importance  The 2008 Physical Activity Guidelines for Americans recommended a minimum of 75 vigorous-intensity or 150 moderate-intensity minutes per week (7.5 metabolic-equivalent hours per week) of aerobic activity for substantial health benefit and suggested additional benefits by doing more than double this amount. However, the upper limit ...

Importance  Few studies have examined how different proportions of moderate and vigorous physical activity affect health outcomes.

Objective  To examine whether the proportion of total moderate to vigorous activity (MVPA) that is achieved through vigorous activity is associated with all-cause mortality independently of the total amount ...

Todd M. Manini, PhD

The overall health benefits of physical activity have been known for several decades. It is clear that consistent participation in physical activity leads to large physiologic adaptations that are closely connected to improved cardiorespiratory, vascular, musculoskeletal, mental, and metabolic health. These effects are pervasive across the lifespan. In ...

Importance  Percutaneous ventricular assist devices (PVADs) provide robust hemodynamic support compared with intra-aortic balloon pumps (IABPs), but clinical use patterns are unknown.

Objective  To examine contemporary patterns in PVAD use in the United States and compare them with use of IABPs.

Importance  Although the end-of-life care patients receive is known to vary across nations, regions, and centers, these differences are best explored within a group of patients with presumably similar care preferences.

Objective  To examine the proportions of patients admitted to the intensive care unit (ICU) with ...

In this issue of JAMA Internal Medicine, Hart and colleagues 1 provide, to our knowledge, the first known epidemiologic data on treatment patterns among patients admitted to the intensive care unit (ICU) with preexisting treatment limitations. Treatment limitations are explicit statements by the patient, documented in the ...

Editor's Note 
Joseph S. Ross, MD, MHS

The intra-aortic balloon pump (IABP), a mechanical device designed to increase both myocardial perfusion and cardiac output, was pioneered in the 1960s to treat patients in cardiogenic shock. An innovation at the time, the device was made available for use prior to passage of the 1976 Medical Device ...
