Infection remains a common cause of morbidity and mortality in patients with both left ventricular assist devices (LVADs) and cardiac implanted electronic devices (CIEDs) with limited data describing outcomes in patients who have both devices implanted. We performed a single-center, retrospective, observational cohort study of patients with both a transvenous CIED and LVAD who developed bacteremia. Ninety-one patients were evaluated.

Objectives: Delirium is a common postoperative complication associated with death and long-term cognitive impairment. The authors studied the association between opioid-sparing anesthetics, incorporating Enhanced Recovery After Cardiac Surgery (ERACS)-guided analgesics and postoperative delirium.

Design: The authors performed a retrospective review of nonemergent coronary, valve, or ascending aorta surgery patients.

Objective: To determine whether pursuit of an advanced degree during dedicated research time (DRT) in a general surgery residency training program impacts a resident's research productivity.

Design: A retrospective, multi-institutional cohort study.

Setting: General surgery residency programs that were approved to graduate more than 5 categorical residents per year and that offered at least 1 year of DRT were contacted for participation in the study.

Motile cilia are essential for clearance of particulates and pathogens from airways. For effective transport, ciliary motor proteins and axonemal structures interact to generate the rhythmic, propulsive bending, but the mechanisms that produce a dynamic waveform remain incompletely understood. Biomechanical measures of human ciliary motion and their relationships to ciliary assembly are needed to illuminate the biophysics of normal ciliary function and to quantify dysfunction in ciliopathies.
