The MBA in Medical Education: Current MD/MBA Student Aspirations, Perceptions, and Motivations.

BACKGROUND: As combined Doctor of Medicine and Master of Business Administration (MD/MBA) programs gain popularity, it is critical to understand the motives, perceptions, and interests of MD/MBA students. The purpose of this study was to investigate career aspirations of MD/MBA students, skills they perceive to gain from the dual degree, and reasons why students enroll in MD/MBA programs. MATERIALS AND METHODS: All 73 MD/MBA programs in the United States were invited to participate in a twelve-question, online survey. Responses were collected between August 2019 and February 2020 from students enrolled during the 2019-2020 academic year. The questions were designed to examine career aspirations, program perceptions, and personal motivations. Data were aggregated into descriptive summary statistics and rank orders. RESULTS: A total of 18 MD/MBA programs agreed to participate in this study, of which 14 met criteria for final analysis. From these programs, 67 of 175 students responded (38%). Among respondents, 100% planned to pursue residency. The most common career interests included the following: clinical practice at an academic hospital (85%), executive leadership in a hospital network (76%), and clinical practice in a community hospital (65%). Students ranked "making a broader impact on health care" and "pursuing leadership in clinical practice" highest among reasons to pursue an MD/MBA. Students reported high rates of acquiring MBA-oriented skills. CONCLUSIONS: MD/MBA students in this study focused on pursuing clinical careers. Students appear satisfied with their education, reporting high rates of skill acquisition. Residency programs interested in MD/MBA students can incorporate leadership and entrepreneurial opportunities to foster students' broad interests.

Patient-reported outcomes of meniscal repair and meniscectomy in patients 40 years of age and older show similar good results.

The purpose of this study is to evaluate patient-reported outcome measures (PROMs) in patients aged 40 years and older who underwent meniscal repair or meniscectomy. All patients aged 40 and older who underwent a meniscal repair at a single institution from 2006 to 2017 were included. Meniscal repair cases were matched with a meniscectomy control group in a 1:3 ratio, selected for an equal proportion of concomitant ACL reconstruction in each group. PROMs, collected at a minimum follow-up of 24 months, included International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), Marx activity scale, and a patient satisfaction scale. The primary outcome was IKDC score, which was compared between groups using a Mann-Whitney U test. Rate of failure, defined as repeat ipsilateral knee surgery or surgeon report of failure, was reported. Thirty-five meniscal repair patients and 131 meniscectomy patients were identified; 28 (80.0%) and 67 (51.1%) completed all PROMs with mean follow-up of 4.9 and 5.2 years, respectively. The mean age was 48.5 ± 7.0 years in the meniscal repair cohort and 52.8 ± 7.1 years in the meniscectomy cohort (p = 0.009). Concomitant ACL reconstruction was present in 46.4% and 49.3% of the meniscal repair and meniscectomy cohorts, respectively (n.s.). The median IKDC score was 78 (IQR 66, 87) in the repair cohort and 77 (IQR 56, 86) in the meniscectomy cohort (n.s.). The median Marx activity scale was 3.5 (IQR 0, 8) in the repair cohort and 3.0 (IQR 0, 9) in the meniscectomy cohort (n.s.). Over 85% of both groups were satisfied or very satisfied with no between-group differences (n.s.). In patients aged 40 years and older, patient-reported outcomes at an average of 5 years postoperatively were satisfactory and similar in patients undergoing meniscal repair and meniscectomy, indicating that age alone should not be a contraindication to meniscal repair.Level of evidence: Level III.

In canine bacterial pneumonia circulating granulocyte counts determine outcome from donor cells.

BACKGROUND: In experimental canine septic shock, depressed circulating granulocyte counts were associated with a poor outcome and increasing counts with prophylactic granulocyte colony-stimulating factor (G-CSF) improved outcome. Therapeutic G-CSF, in contrast, did not improve circulating counts or outcome, and therefore investigation was undertaken to determine whether transfusing granulocytes therapeutically would improve outcome. STUDY DESIGN AND METHODS: Twenty-eight purpose-bred beagles underwent an intrabronchial Staphylococcus aureus challenge and 4 hours later were randomly assigned to granulocyte (40-100 × 109 cells) or plasma transfusion. RESULTS: Granulocyte transfusion significantly expanded the low circulating counts for hours compared to septic controls but was not associated with significant mortality benefit (1/14, 7% vs. 2/14, 14%, respectively; p = 0.29). Septic animals with higher granulocyte count at 4 hours (median [interquartile range] of 3.81 3.39-5.05] vs. 1.77 [1.25-2.50]) had significantly increased survival independent of whether they were transfused with granulocytes. In a subgroup analysis, animals with higher circulating granulocyte counts receiving donor granulocytes had worsened lung injury compared to septic controls. Conversely, donor granulocytes decreased lung injury in septic animals with lower counts. CONCLUSION: During bacterial pneumonia, circulating counts predict the outcome of transfusing granulocytes. With low but normal counts, transfusing granulocytes does not improve survival and injures the lung, whereas for animals with very low counts, but not absolute neutropenia, granulocyte transfusion improves lung function.

Haptoglobin improves shock, lung injury, and survival in canine pneumonia.

During the last half-century, numerous antiinflammatory agents were tested in dozens of clinical trials and have proven ineffective for treating septic shock. The observation in multiple studies that cell-free hemoglobin (CFH) levels are elevated during clinical sepsis and that the degree of increase correlates with higher mortality suggests an alternative approach. Human haptoglobin binds CFH with high affinity and, therefore, can potentially reduce iron availability and oxidative activity. CFH levels are elevated over approximately 24-48 hours in our antibiotic-treated canine model of S. aureus pneumonia that simulates the cardiovascular abnormalities of human septic shock. In this 96-hour model, resuscitative treatments, mechanical ventilation, sedation, and continuous care are translatable to management in human intensive care units. We found, in this S. aureus pneumonia model inducing septic shock, that commercial human haptoglobin concentrate infusions over 48-hours bind canine CFH, increase CFH clearance, and lower circulating iron. Over the 96-hour study, this treatment was associated with an improved metabolic profile (pH, lactate), less lung injury, reversal of shock, and increased survival. Haptoglobin binding compartmentalized CFH to the intravascular space. This observation, in combination with increasing CFHs clearance, reduced available iron as a potential source of bacterial nutrition while decreasing the ability for CFH and iron to cause extravascular oxidative tissue injury. In contrast, haptoglobin therapy had no measurable antiinflammatory effect on elevations in proinflammatory C-reactive protein and cytokine levels. Haptoglobin therapy enhances normal host defense mechanisms in contrast to previously studied antiinflammatory sepsis therapies, making it a biologically plausible novel approach to treat septic shock.
