TL;DR: This large, multicenter series demonstrates that transmural, minimally invasive endoscopic débridement of WOPN performed in the United States is an efficacious and reproducible technique with an acceptable safety profile.
Journal ArticleDOI
Variation in the prevalence of sarcopenia and sarcopenic obesity in older adults associated with different research definitions: dual-energy X-ray absorptiometry data from the National Health and Nutrition Examination Survey 1999-2004.
John A. Batsis,Laura K. Barre,Todd A. MacKenzie,Sarah I. Pratt,Francisco Lopez-Jimenez,Stephen J. Bartels +5 more
TL;DR: To determine the prevalence range for sarcopenic obesity and its relationship with sex, age, and ethnicity, a large number of patients with the condition are randomly assigned to receive either statins or statins.
Journal ArticleDOI
Diagnostic accuracy of body mass index to identify obesity in older adults: NHANES 1999–2004
John A. Batsis,Todd A. MacKenzie,Stephen J. Bartels,Stephen J. Bartels,Karine R. Sahakyan,Virend K. Somers,Francisco Lopez-Jimenez +6 more
TL;DR: The diagnostic accuracy of BMI is determined using dual-energy X-ray absorptiometry (DEXA) in assessing the degree of obesity in older adults, suggesting that BMI may be a suboptimal marker for adiposity in elderly adults.
Journal ArticleDOI
Sarcopenia, sarcopenic obesity, and functional impairments in older adults: National Health and Nutrition Examination Surveys 1999-2004.
John A. Batsis,Todd A. MacKenzie,Francisco Lopez-Jimenez,Stephen J. Bartels,Stephen J. Bartels +4 more
TL;DR: A uniform definition is needed to identify and characterize these high-risk populations of sarcopenia and sarcopenic obesity, as well as the association of physical limitations, basic and instrumental activities of daily living and sarc Openia status.
Journal ArticleDOI
Perioperative Increases in Serum Creatinine Are Predictive of Increased 90-Day Mortality After Coronary Artery Bypass Graft Surgery
Jeremiah R. Brown,Richard P. Cochran,Lawrence J. Dacey,Cathy S. Ross,Karyn S. Kunzelman,Robert F. Dunton,John H. Braxton,David C. Charlesworth,Robert A. Clough,Robert E. Helm,Bruce J. Leavitt,Todd A. MacKenzie,Gerald T. O'Connor +12 more
TL;DR: Patients with large creatinine increases after CABG surgery have a higher 90-day mortality compared with patients with small increases, and efforts to identify patients with impaired renal function and to preserve renal function before cardiac surgery may yield benefits for patients in the future.
