Correlating clinical assessment and MRI findings in diagnosing calf injuries in elite male Australian rules footballers.

OBJECTIVE: Calf complex injuries represent a significant injury burden among Australian Rules athletes. To date, there has been limited research correlating clinical and radiological findings of pathology within the calf. The objective of this study is to determine how accurately magnetic resonance imaging (MRI) findings correlate with clinical measures of calf muscle complex pathology in elite male athletes. MATERIALS AND METHODS: A prospective cohort study was conducted on Australian rules elite athletes. A cohort of 45 athletes underwent a high-load training session of approximately 10 km of running. Athletes were then assessed by a sports physiotherapist who made a diagnosis of no pathology, delayed onset muscle soreness, strain or other. Subsequently, the athletes underwent MRI of their bilateral calf complexes. Radiologists interpreted the MRI findings and radiological diagnosis were correlated with clinical diagnosis. RESULTS: A total of 90 calf MRIs were performed. Correlation of clinical and radiological diagnosis occurred in 57 cases. Of the 33 cases which did not correlate, there were 4 radiologically significant acute calf strains in clinically asymptomatic athletes, 3 of which involved old scar tissue. CONCLUSION: MRI may detect clinically insignificant injuries within the calf complex. If an athlete does not have any clinically relevant symptoms, abnormal signal on MRI may represent a different diagnosis to muscle strain. Signal change on MRI proximal to scar tissue may represent reactive oedema. Clinical history and examination should be correlated with radiological findings is recommended when diagnosing calf injury in elite athletes.

Surgery investigators funded through the National Institutes of Health: A rebirth.

BACKGROUND: Funding toward surgical research through the National Institutes of Health has decreased relative to other medical specialties. This study was initiated to characterize features of academically successful surgeon-scientists and departments of surgery. We hypothesized that there may be decreases in young investigators obtaining independent National Institutes of Health awards and that successful academic departments of surgery may be depending increasingly on PhD faculty. METHODS: The National Institutes of Health RePORTER database was queried for grants awarded to departments of surgery during fiscal years 2003 and 2013. Grant summaries were categorized by research methodology. Training of the principal investigator and academic position were determined through the RePORTER database and publicly available academic biographies. Institutions were ranked by number of grants funded. RESULTS: Between 2003 and 2013, total surgery grants awarded decreased by 19%. The number of National Institutes of Health-funded, clinically active surgeons (MDs) decreased 11%, while funded PhDs increased 9%; however, clinically active junior faculty have comprised an increasing proportion of funded MDs (from 20-38%). Shifts in research topics include an increasing proportion of investigators engaged in outcomes research. Among institutions ranking in the top 20 for surgical research in both 2003 and 2013 (N = 15), the ratio of MDs to PhDs was 2:1 in both fiscal years. Among institutions falling out of the top 20, this ratio was less than 1:1. CONCLUSION: There has been an expansion of outcomes-based surgical research. The most consistently successful institutions are those that actively cultivate MD researchers. Encouragingly, the number of young, independently funded surgeon-scientists in America appears to be increasing.

Recent trends in National Institutes of Health funding for surgery: 2003 to 2013.

BACKGROUND: The purpose of this study is to compare the compositions of federally funded surgical research between 2003 and 2013, and to assess differences in funding trends between surgery and other medical specialties. DATA SOURCES: The National Institutes of Health (NIH) Research Portfolio Online Reporting Tool database was queried for grants within core surgical disciplines during 2003 and 2013. Funding was categorized by award type, methodology, and discipline. Application success rates for surgery and 5 nonsurgical departments were trended over time. CONCLUSIONS: Inflation-adjusted NIH funding for surgical research decreased 19% from $270 M in 2003 to $219 M in 2013, with a shift from R-awards to U-awards. Proportional funding to outcomes research almost tripled, while translational research diminished. Nonsurgical departments have increased NIH application volume over the last 10 years; however, surgery's application volume has been stagnant. To preserve surgery's role in innovative research, new efforts are needed to incentivize an increase in application volume.

Vessel ligation training via an adaptive simulation curriculum.

BACKGROUND: A cost-effective model for open vessel ligation is currently lacking. We hypothesized that a novel, inexpensive vessel ligation simulator can efficiently impart transferrable surgical skills to novice trainees. MATERIALS AND METHODS: VesselBox was designed to simulate vessel ligation using surgical gloves as surrogate vessels. Fourth-year medical students performed ligations using VesselBox and were evaluated by surgical faculty using the Objective Structured Assessments of Technical Skills global rating scale and a task-specific checklist. Subsequently, each student was trained using VesselBox in an adaptive practice session guided by cumulative sum. Posttesting was performed on fresh human cadavers by evaluators blinded to pretest results. RESULTS: Sixteen students completed the study. VesselBox practice sessions averaged 21.8 min per participant (interquartile range 19.5-27.7). Blinded posttests demonstrated increased proficiency, as measured by both Objective Structured Assessments of Technical Skills (3.23 versus 2.29, P < 0.001) and checklist metrics (7.33 versus 4.83, P < 0.001). Median speed improved from 128.2 s to 97.5 s per vessel ligated (P = 0.001). After this adaptive training protocol, practice volume was not associated with posttest performance. CONCLUSIONS: VesselBox is a cost-effective, low-fidelity vessel ligation model suitable for graduating medical students and junior residents. Cumulative sum can facilitate an adaptive, individualized curriculum for simulation training.
