Demographics and characteristics of leadership at allergy and immunology fellowships in the U.S. as of 2022.

Background: The subspecialty of allergy and immunology (AI) has grown tremendously since the first fellowship programs were developed nearly 80 years ago; however, there is little information with regard to the demographic characteristics and trends in training of fellowship directors (FDs). Objective: Our goal was to analyze the demographic characteristics and pathways in training that have led FDs to advance in the field and train the next generation of allergists and immunologists. Methods: We created a list of all current AI fellowship programs and FDs within the United States. Specific biographical, training, and research information was collected via an Internet search and questionnaire responses. The data were recorded and analyzed in a spreadsheet and unpaired t-tests were performed between male versus female groups for H - index comparison to establish if there was a statistically significant difference. Results: There were 84 total AI fellowship programs with 84 FDs. Forty-one FDs (48.8%) were men and 43 FDs (51.2%) were women; mean age was 51.1 years; and the average age at appointment for men was 45.7 years and for women was 41.4 years, with a statistically significant difference (p = 0.02). Self-reported race and ethnicity (77.4% response rate [n = 65]) were as follows: 55.4% white (n = 36), 23.1% Asian (n = 15), 6.2% biracial (n = 4), 7.7% Middle Eastern (n = 5), 4.6% Hispanic (n = 3), and 3.1% Black (n = 2). The average Hirsch-index (h-index) for FDs was 14.2, with an average of 42.1 publications and 1532.2 citations. The difference between the h-index for the men and for the women was statistically significant, being 17.8 and 11.2 respectively, with p = 0.0143. Conclusion: In AI FDs, women were adequately represented, and men and women were hired at similar ages. There was a statistically significant difference in research output (estimated by the h-index) between men and women. This suggests that research output did not limit women in being appointed as FDs.

Leadership Trends at Hand Surgery Fellowships.

BACKGROUND: Fellowship directors (FDs) influence the future of trainees in the field of hand surgery. Currently, there are no studies that analyze the demographic background, institutional training, and academic experience of hand surgery FDs. This study aims to serve as a framework to understand the landscape of current leadership positions in hand surgery education and to identify opportunities to improve FD diversity. METHODS: The American Society for Surgery of the Hand Fellowship Directory was reviewed to include all hand surgery fellowships in the United States. Collected demographic information regarding FDs included age, sex, ethnicity, residency/fellowship training, residency/fellowship graduation year, year hired by current institution, time since training completion until FD appointment, length in FD role, and H-index. RESULTS: Of the 90 FDs included, 86.7% were men and 71.4% self-reported as Caucasian. The average H-index was 13.98 and significantly correlated with age and duration as FD; 71.1% of FDs were trained in orthopedic surgery. The most attended residency program was the University of Pennsylvania; Mayo Clinic and Harvard University were the most represented fellowship programs. CONCLUSION: This review reveals specific trends in demographic backgrounds, institutional training, and academic experiences among current FDs in hand surgery. Our observations, such as racial/ethnic and sex disparities, may offer opportunities to improve the representation of the communities these physicians serve. In addition, the trends described in this study provide objective data among current hand surgery FDs and could serve as a guide for individuals who desire academic leadership roles.

Demographics and Academic Productivity of Cardiothoracic Imaging Fellowship Program Directors in the United States: A Cross-Sectional Review.

Background In this study, we aimed to assess current demographics, measures of academic productivity, and other objective leadership characteristics among United States cardiothoracic imaging fellowship directors (FDs). Methodology A survey was sent to active members listed in the Society of Thoracic Radiology Cardiothoracic Imaging Fellowship Directory. Demographic, post-graduate training, and scholarly activity data were collected, including, but not limited to, age, sex, residency and fellowship training institutions, time since training completion until FD, length of time as FD, and Hirsch-index (h-index) to measure research activity. Results We identified 53 FDs from 50 cardiothoracic imaging fellowship programs. Of these, 31 (58.5%) were male and 22 (41.5%) were female with an average age of 48.5 years (standard deviation (SD) = 8.4, range = 35-67). There was no statistically significant difference between the mean age of male and female FDs (47.5 vs 50.2 years, p = 0.2811). The mean age of appointment to the FD role was 41.8 years. On average, FDs graduated from residency in 2005 and 2007 for fellowships. Most attended allopathic medical schools (52/53, 98.1%). The average Scopus h-index was 15.7 (SD = 17.4). Gender-wise comparison of mean h-indices revealed 16.2 for males and 15 for females, with no statistically significant difference between the two groups (p = 0.81). Ten (18.9%) FDs and 20 (37.7%) FDs were at the same location they completed residency and fellowship training, respectively. Conclusions This cross-sectional study shows the present demographics within the cardiothoracic radiology FD position. This field of radiology is observed to have FDs with research productivity that is comparable with other medical specialties. Some radiology residency and fellowship programs were shown to produce more FDs than others; however, we were not able to identify causality. Program directors appear to be selected from a familiar pool of applicants, and ultimately FDs are being replaced by individuals with similar distinctions. Overall, this research into cardiothoracic radiology FDs demographics and research productivity can add to the current body of literature on FDs in various medical specialties. It is important to continue to reflect on medical leadership as the field continues to advance.

Trends in leadership at orthopaedic surgery sports medicine fellowships.

BACKGROUND: Fellowship directors (FDs) in sports medicine influence the future of trainees in the field of orthopaedics. Understanding the characteristics these leaders share must be brought into focus. For all current sports medicine FDs, our group analyzed their demographic background, institutional training, and academic experience. AIM: To serve as a framework for those aspiring to achieve this position in orthopaedics and also identify opportunities to improve the position. METHODS: Fellowship programs were identified using both the American Orthopaedic Society for Sports Medicine and the Arthroscopy Association of North America Sports Medicine Fellowship Directories. The demographic and educational background data for each FD was gathered via author review of current curriculum vitae (CVs). Any information that was unavailable on CV review was gathered from institutional biographies, Scopus Web of Science, and emailed questionnaires. To ensure the collection of as many data points as possible, fellowship program coordinators, orthopaedic department offices and FDs were directly contacted via phone if there was no response via email. Demographic information of interest included: Age, gender, ethnicity, residency/fellowship training, residency/fellowship graduation year, year hired by current institution, time since training completion until FD appointment, length in FD role, status as a team physician and H-index. RESULTS: Information was gathered for 82 FDs. Of these, 97.5% (n = 80) of the leadership were male; 84.15% (n = 69) were Caucasian, 7.32% (n = 6) were Asian-American, 2.44% (n = 2) were Hispanic and 2.44% (n = 2) were African American, and 3.66% (n = 3) were of another race or ethnicity. The mean age of current FDs was 56 years old (± 9.00 years), and the mean Scopus H-index was 23.49 (± 16.57). The mean calendar years for completion of residency and fellowship training were 1996 (± 15 years) and 1997 (± 9.51 years), respectively. The time since fellowship training completion until FD appointment was 9.77 years. 17.07% (n = 14) of FDs currently work at the same institution where they completed residency training; 21.95% (n = 18) of FDs work at the same institution where they completed fellowship training; and 6.10% (n = 5) work at the same institution where they completed both residency and fellowship training. Additionally, 69.5% (n = 57) are also team physicians at the professional and/or collegiate level. Of those that were found to currently serve as team physicians, 56.14% (n = 32) of them worked with professional sports teams, 29.82% (n = 17) with collegiate sports teams, and 14.04% (n = 8) with both professional and collegiate sports teams. Seven residency programs produced the greatest number of future FDs, included programs produced at least three future FDs. Seven fellowship programs produced the greatest number of future FDs, included programs produced at least four future FDs. Eight FDs (9.75%) completed two fellowships and three FDs (3.66%) finished three fellowships. Three FDs (3.66%) did not graduate from any fellowship training program. The Scopus H-indices for FDs are displayed as ranges that include 1 to 15 (31.71%, n = 26), 15 to 30 (34.15%, n = 28), 30 to 45 (20.73%, n = 17), 45 to 60 (6.10%, n = 5) and 60 to 80 (3.66%, n = 3). Specifically, the most impactful FD in research currently has a Scopus H-index value of 79. By comparison, the tenth most impactful FD in research had a Scopus H-index value of 43 (accessed December 1, 2019). CONCLUSION: This study provides an overview of current sports medicine FDs within the United States and functions as a guide to direct initiatives to achieve diversity equality.

Trends in Leadership at Orthopedic Surgery Adult Reconstruction Fellowships.

BACKGROUND: Fellowship directors (FDs) in adult reconstruction have a profound impact on current and future trainees within orthopedics. Our group sought to evaluate the shared characteristics among current adult reconstruction FDs to provide a framework for those aspiring to achieve this position and identify possible areas of improvement. METHODS: Fellowship programs were identified using the American Association of Hip and Knee Surgeons Directory. Data for each FD were gathered via electronic mail, telephone, curriculum vitae, and online searches. Demographic information collected included age, gender, ethnicity, residency/fellowship training, residency/fellowship graduation year, year hired by current institution, time since training completion until FD appointment, length in FD role, and Scopus H-index. RESULTS: Information was gathered for 94 FDs. Of these, 100% were males; 80.6% were Caucasian, 12.90% were Asian American, 5.38% were Hispanic, and 1.08% were African American. The average age (52.6 years old), H-index (16.54), year of residency (2000) and fellowship (2001) graduation, and time since training until FD appointment (9.55 years) were analyzed. The top training programs to produce future FDs were Mayo Clinic (residency) and Harvard University (fellowship). CONCLUSION: Adult reconstruction FDs are frequently distinguished by their level of research productivity and experience, but certainly more demographic diversity is needed within this cohort. Specific training programs may inherently have a vital role in the development of individuals for future leadership positions. These developments could be a result of unique features inherent to the training programs or because of a subset of applicants who pursue specific programs with aspirations of subsequent leadership opportunities.

Reproductive life-history strategies in a species-rich assemblage of Amazonian electric fishes.

The reproductive biology of only a small fraction of Neotropical freshwater fishes has been described, and detailed comparative studies of reproductive life-history variation in the Neotropical ichthyofauna are lacking. Here we describe interspecific variation in reproductive life history for a multi-species assemblage of the electric knifefish genus Brachyhypopomus (Hypopomidae: Gymnotiformes: Ostariophysi) from Amazonian floodplain and terra firme stream systems. During a year-round quantitative sampling program, we collected and measured key life-history traits from 3,410 individuals. Based on oocyte size distributions, and on circannual variation in gonadosomatic indices, hepatosomatic indices, and capture-per-unit-effort abundance of reproductive adults, we concluded that all species exhibit a single protracted annual breeding season during which females spawn fractionally. We found small clusters of post-larval individuals in one floodplain species and one terra firme stream species, but no signs of parental care. From analyses of body size-frequency distributions and otolith growth increments, we concluded that five species in our study area have approximately one-year (annual) semelparous life history with a single reproductive period followed by death, while two species have a two-year iteroparous life history, with breeding in both year-groups. Despite predictions from life-history theory we found no salient correlations between life history strategy (semelparity or iteroparity) and habitat occupancy (floodplain or terra firme stream). In the iteroparous species B. beebei, we documented evidence for reproductive restraint in the first breeding season relative to the second breeding season and argue that this is consistent with age-regulated terminal investment.

Oxytocin in the tumor microenvironment is associated with lower inflammation and longer survival in advanced epithelial ovarian cancer patients.

BACKGROUND: Prior research demonstrates a protective role for oxytocin in ovarian cancer based on its anti-proliferative, anti-migratory, and anti-invasive effects in vitro and in vivo. However, the role of endogenous oxytocin has not been examined in ovarian cancer patients. Oxytocin also has anti-inflammatory properties that have not been examined in cancer. The purpose of this investigation was to examine relationships between endogenous oxytocin, tumor-associated inflammation (interleukin-6), and survival in advanced epithelial ovarian cancer patients. METHODS: Tumor microenvironment (ascites) and plasma oxytocin levels were analyzed via ELISA on extracted samples obtained from 79 patients. In vitro models were used to characterize oxytocin and oxytocin receptor expression in four ovarian cancer cell lines and to investigate direct anti-inflammatory effects of oxytocin on tumor cell secretion of interleukin-6. High and variable levels of oxytocin were observed in ascites, up to 200 times greater than in plasma. Higher levels of ascites oxytocin were associated with lower levels of systemic and tumor-associated interleukin-6, an inflammatory cytokine implicated in ovarian tumor progression. Oxytocin also attenuated interleukin-6 secretion from multiple ovarian tumor cell lines in vitro. Higher levels of ascites oxytocin were associated with a significant survival advantage and statistical mediation analyses suggested this effect was partially mediated by interleukin-6. CONCLUSIONS: These data identify a previously unacknowledged hormone in the ovarian tumor microenvironment and provide initial evidence that oxytocin has protective effects in ovarian cancer via anti-inflammatory mechanisms. Future studies should examine the therapeutic utility of oxytocin.
