Midterm survival, clinical, and hemodynamic outcomes of a novel mechanical mitral valve prosthesis.

Objective: To evaluate the midterm survival, clinical, and hemodynamic outcomes of the On-X mechanical mitral valve, based on the 5-year results of the Prospective Randomized On-X Anticoagulation Clinical Trial (PROACT).

Method: PROACT Mitral was a multicenter study evaluating 401 patients who underwent mitral valve replacement (MVR) with either Standard or Conform-X On-X mitral valves, comparing low-dose and standard-dose warfarin. Here we report prespecified secondary outcomes of survival, New York Heart Association (NYHA) functional classification, and valve hemodynamics as assessed by core lab-adjudicated echocardiography at 1, 3, and 5 years in the pooled population.

Determination of MexXY-OprM substrate profile in a major efflux knockout system reveals distinct antibiotic substrate classes.

Defining the substrates of Resistance-Nodulation-Division (RND) systems is often complicated by the presence of multiple systems in a single bacterial species. Using a major efflux knockout strain, we developed a system that enables controlled expression of MexXY-OprM in the absence of background efflux complexes with overlapping substrate profiles. This system identified three groups of potential substrates: substrates, partial substrates, and nonsubstrates, and defined trimethoprim as a new substrate for MexXY-OprM.

Diversity in the US Academic Microsurgery Pathway.

Although the representation of women and ethnic minority students in the US medical schools has recently increased, discrepancies in representation among plastic surgery residents and faculty continue. The state of sex and ethnic diversity in academic microsurgery remains minimally investigated. We aimed to evaluate the sex, race, and ethnicity demographics among academic microsurgeons and identify underrepresentation along the leadership pathway.

Remaining Steadfast on Diversity and Inclusion in Plastic Surgery.

Organized plastic and reconstructive surgery has recognized the importance of diversity for optimal patient care and advancement of the specialty. Initial goals focused on increasing opportunities for underrepresented members of the society: women and Blacks and Hispanic/Latino members. The diversity lens has expanded to not only include race and sex but also diversity of religion, sexual orientation, gender identity, disability, geography, economic status, membership status, and employment type.

Critical Assessment of Fellowship Director Gender and Ethnic Diversity across the Five Major Plastic Surgery Fellowships.

Background: Subspecialty fellowship directors are essential to the selection and mentorship of trainees. The purpose of this study is to evaluate the gender and racial/ethnic diversity of fellowship directors across fellowship programs in plastic and reconstructive surgery (PRS).
