Intraoperative Goal-Directed Perfusion Improves Outcomes in Left Ventricular Assist Device Explant Heart Transplantation.

Left ventricular assist device (LVAD) explant heart transplantation represents a metabolically vulnerable population with an increased risk for renal failure and mortality. Oxygen extraction ratio (O2ER), which integrates oxygen delivery and tissue oxygen demand, may provide a physiologic marker of cumulative metabolic...

Does Postoperative Glycemic Control Lead to Worse Outcomes in Adult Spinal Deformity Surgery? A Study of Diabetic and Nondiabetic Patients.

BACKGROUND AND OBJECTIVES Postoperative hyperglycemia is a known risk factor of complications after surgery. In patients undergoing adult spinal deformity (ASD) surgery, we evaluated the effect of postoperative hyperglycemia in diabetics and nondiabetics on: (1) medical complications, (2) mechanical complications, and...

Impaired Proteostasis is an Early Feature of the Diabetic Heart in Humans and Mice

Diabetes and obesity increase cardiac lipid levels leading to cardiomyopathy and heart failure. We hypothesized that intermittent fasting would reduce cardiac lipid levels. Surprisingly, intermittent fasting increased myocardial triglyceride content, but rescued mortality and attenuated cardiomyopathy in mice overexpre...

Bridge or Burden? Heart Transplant Outcomes Following Left Ventricular Assist Device Explant in the Contemporary Allocation Era.

These findings suggest LVAD explant identifies a higher-risk transplant phenotype shaped by surgical burden, device-associated physiologic effects, and allocation-era transplant timing, rather than by intrinsic device-related risk alone.

Correction of the Lumbosacral Fractional Curve vs. Thoracolumbar Major Curves in Adult Spinal Deformity Surgery: How Much Do We Correct Each Curve?

OBJECTIVE In adult spinal deformity (ASD) surgery, lumbosacral fractional curve (LSF) is stiffer and harder to correct than thoracolumbar major curve (MC). In patients undergoing ASD surgery, we aimed to:1) assess correction rate of LSF vs. MC, 2) determine association between their correction and postoperative alignme...

How changes in segmental lordosis impact L1-pelvic-angle after adult spinal deformity surgery: Which lumbar levels matter most?

Focusing on adding lordosis at the L4/5 and L5/S1 level will result in the greatest improvement in L1PA, suggesting that focusing on adding lordosis at the L4/5 and L5/S1 level will result in the greatest improvement in L1PA.
