Hurdles in Diversifying Otolaryngology: A Survey of Medical Students.

The field of otolaryngology has one of the lowest rates of racial and ethnic diversity. An anonymous survey was distributed to members of the Student National Medical Association at different medical schools to identify factors that may contribute to this disparity. Responses were received from 104 students at 36 allopathic medical schools. Most respondents identified as black (86.5%). One-third of students (34.6%) noted that they were discouraged from pursuing otolaryngology due to lack of mentorship, and among these students, most noted that they lack mentors of the same race (75%). One-fourth of respondents (25%) indicated that they lack a home otolaryngology program. The most common reasons for participants' disinterest in otolaryngology included competitiveness, inadequate exposure, research, and the high board scores needed to match. This hypothesis-generating, proof-of-concept study highlights potential barriers that may discourage underrepresented medical students from pursuing a career in otolaryngology.

Increased body mass index predicts prolonged survival in patients with head and neck squamous cell carcinoma.

BACKGROUND: Higher body mass index (BMI) may have a protective effect on survival in patients with head and neck cancer. The aim of this study was to determine the effect of BMI on overall survival (OS) in veterans with head and neck squamous cell carcinoma (HNSCC). METHODS: A cohort of 702 patients diagnosed with HNSCC between 1995 and 2019 were identified at the Washington DC Veterans Affairs Medical Center, and 342 patients were included for analysis. Records were queried for clinical-demographic data, BMI, and outcomes. RESULTS: HNSCC patients categorized as overweight or obese at time of diagnosis had a lower 3-year risk of death (p = 0.033) and improved OS (p < 0.001) compared to patients who were underweight or normal weight. The majority of locoregional recurrences occurred in patients with low or normal pretreatment BMI. CONCLUSIONS: Higher BMI at diagnosis may have a protective effect on OS in veterans with HNSCC.

The Role of Neuregulin and Stem Cells as Therapy Post-Myocardial Infarction.

Coronary artery disease, including myocardial infarction (MI), is a leading cause of morbidity and mortality in the United States. Due to the limited self-renewal capacity of cardiac tissue, MIs can lead to progressive heart disease with a lasting impact on health and quality of life. The recent discovery of cardiac stem cells has incited research into their potential therapeutic applications for patients suffering from cardiovascular disease. Studies have demonstrated the ability of stem cells to both generate cardiac tissues in vitro and aid in the recovery of cardiovascular function in vivo in animal models. However, the long-term efficacy of stem cells as regenerative therapy is still unknown. Exploration of alternative therapies is underway, including the use of cardiac growth factor neuregulin-1 (NRG-1). Research has demonstrated that NRG-1 not only has direct effects on cardiomyocytes (CM) but also acts within the tissues supporting the CM. Transplantation of NRG-1 into ischemic cardiac tissue mitigates the progression of heart failure and can reverse cardiac remodeling. Recent publications have sought to study the combined use of these agents, and while the results are promising, they do warrant further research. This review aims to consider these therapies separately as well as in combination.
