RESUMO
BACKGROUND: For over 50 years, the United States (US) used affirmative action as one strategy to increase diversity in higher education including medical programs, citing benefits including training future public and private sector leaders. However, the recent US Supreme Court ending affirmative action in college admissions threatens advancements in the diversity of medical college faculty. OBJECTIVE: Our study evaluated the demographic trends in Internal Medicine (IM) faculty in the US by assessing sex and race/ethnicity diversity to investigate who is likely to be impacted most with the end of affirmative action. DESIGN: Longitudinal retrospective analysis SUBJECTS: IM faculty from the Association of American Medical Colleges faculty roster from 1966 to 2021 who self-reported sex and ethnicity MAIN OUTCOMES: The primary study measurement was the annual proportion of women and racial/ethnic groups among IM faculty based on academic rank and department chairs. RESULTS: Although racial/ethnic diversity increased throughout the era of affirmative action, African American, Hispanic, and American Indian populations remain underrepresented. White physicians occupied > 50% of faculty positions across academic ranks and department chairs. Among the non-White professors, Asian faculty had the most significant increase in proportion from 1966 to 2021 (0.6 to 16.6%). The percentage of women increased in the ranks of professor, associate professor, assistant professor, and instructor by 19.5%, 27.8%, 25.6%, and 26.9%, respectively. However, the proportion of women and racial/ethnic minority faculty decreased as academic rank increased. CONCLUSION: Despite an increase in the representation of women and racial/ethnic minority IM faculty, there continues to be a predominance of White and men physicians in higher academic ranks. With the end of affirmative action, this trend has the danger of being perpetuated, resulting in decreasing diversity among IM faculty, potentially impacting patient access and health outcomes.

INTRODUCTION AND HYPOTHESIS: Urogynecology fellowship program websites are an important source of information to potential applicants, especially given the ongoing COVID-19 pandemic and resulting travel restrictions. Our study evaluated the publicly available information on American and Canadian urogynecology fellowship websites and present recommendations for website content development to promote the subspecialty of urogynecology. METHODS: Data were collected from all active American and Canadian urogynecology fellowship program websites between May and June 2020 against 72 criteria developed from previously published studies. The criteria included the following sections: Recruitment, Faculty Information, Current Fellows, Research and Education, Surgical Program, Clinical Work, Benefits and Career Planning, Wellness, and Environment. RESULTS: 54 American urogynecology program websites and 11 Canadian urogynecology program websites were analyzed. The mean score of American and Canadian websites was 46.46% (n = 33.45 ± 7.20 out of 72) and 27.40% (n = 19.73 ± 3.77 out of 72), respectively. American program websites scored significantly higher on available information than Canadian websites. The highest prevalence section across American websites was Wellness (64%, n = 1.92 ± 0.85 out of 3 criteria) while the lowest prevalence section was Clinical Work (15.17%, n = 0.91 ± 1.02 out of 6 criteria). Comparatively, Canadian websites scored highest in the Faculty Information section (43.12%, 3.45 ± 2.02) and lowest in the Clinical Work section (6%, n = 0.36 ± 0.67 out of 6 criteria). CONCLUSIONS: American and Canadian websites thoroughly covered the Wellness and Faculty Information sections, respectively. Program websites should consider adding details about Benefits and Career Planning and Clinical Work.

OBJECTIVE: The purpose of our study was to assess the comprehensiveness of Canadian obstetrics and gynaecology residency and fellowship program websites to understand the quality of information available to prospective students and make recommendations, if needed. METHODS: All active residency and fellowship program websites (as of May 2020) were evaluated and compared using 72-point criteria in the following domains: Recruitment, Faculty, Current Residents/Fellows, Research and Education, Surgical Procedures, Clinical Work, Benefits and Incentives, Wellness, and Environment. Programs without websites were excluded from the study. Program website information availability was compared by geographic region. RESULTS: Out of the identified 80 residency and fellowship programs, 68.75% (55) were from central Canada, 6.25% (5) from Atlantic Canada, and 25% (20) from western Canada. The mean score for residency websites was 25.4 ± 7.59 (35.6% of criteria complete). The domains with the highest and lowest inclusion rates were Research and Education (46.3% criteria complete) and Current Residents (16.2% criteria complete). The mean score of fellowship websites was 27.9 ± 8.89 (38.8% criteria complete). For fellowship websites, Wellness had the highest inclusion rate (66.0% criteria complete), while Current Fellows had the lowest (13.2% criteria complete). Overall, fellowship websites scored higher than residency websites (27.9 ± 8.89 and 25.4 ± 7.59 out of 72 criteria, respectively). CONCLUSION: Overall, Canadian postgraduate obstetrics and gynaecology program websites include information on many topics relevant to prospective students, such as research, education, and wellness. Programs should provide more information about work hours, call schedules, and current trainees. Lastly, there is an opportunity for programs in western and Atlantic Canada to increase the comprehensiveness of their websites.

BACKGROUND: Krüppel-type zinc finger protein genes located on chromosome 19q13 are aberrantly hypermethylated with high frequency in all anatomic sub-sites of head and neck cancers as well as other epithelial tumours resulting in decreased expression. METHODS: We examined prognostic significance of ZNF154 and ZNF132 expression and DNA methylation in independent patient cohort of about 500 head and neck cancer patients in the Cancer Genome Atlas (TCGA). We also overexpressed these genes in HEK-293 cells, as well as the oral cancer cell line UM-SCC-1. RESULTS: In 20 patients from the TCGA cohort of HNSCC patients where ZNF154 and ZNF132 DNA methylation and RNA expression could be compared in tumor and adjacent normal tissue, there was increased DNA methylation and decreased expression of both ZNF154 and ZNF132 in primary tumours. Low ZNF154 and low ZNF132 expression were associated with shorter overall survival in both head and neck squamous cell carcinoma (HNSCC) and lung adenocarcinoma (LUAC patients). While expression of these proteins in HEK-293 cells produced full-length protein, only truncated copies could be expressed in head and neck cancer cells (UM-SCC-1). The truncated version of ZNF154 protein increased doubling time and reduced cell migration in UM-SCC-1 cancer cells. CONCLUSIONS: Both ZNF132 and ZNF154 represent novel clinically significant biomarkers in head and neck cancer with potential tumour suppressive properties. Future studies will address the underlying molecular mechanisms by which ZNF154 expression in HNSCC contributes to the control of cell growth and migration.

INTRODUCTION: The pathophysiologic differences between methacholine-induced cough but normal airway sensitivity (COUGH) and healthy individuals (CONTROL) are incompletely understood and may be due to differences in the bronchodilating effect of deep inspirations (DIs). The purpose of this study is to compare the bronchodilating effect of DIs in individuals with classic asthma (CA), cough variant asthma (CVA), and COUGH with CONTROL and to assess impulse oscillometry (IOS) measures as predictors of the bronchodilating effect of DIs. METHODS: A total of 43 adults [18 female; 44.8 ± 12.3 years (mean ± SD); n = 11 CA, n = 10 CVA, n = 7 COUGH, n = 15 CONTROL] underwent modified high-dose methacholine challenge, with IOS and partial/maximal expiratory flow volume (PEFV/MEFV) maneuvers (used to calculate DI Index) to a maximum change (Δ) in FEV1 of 50% from baseline (MAX). Cough count and dyspnea were measured at each dose. The relation between IOS parameters and DI Index was assessed at baseline and MAX using multivariable linear regression analysis. RESULTS: Cough frequency, dyspnea intensity, and baseline peripheral resistance (R5-R20) were significantly greater in COUGH compared with CONTROL (p = 0.006, p = 0.029, and p = 0.035, respectively). At MAX, the DI Index was significantly lower in COUGH (0.01 ± 0.36) compared with CA (0.67 ± 0.97, p = 0.008), CVA (0.51 ± 0.73, p = 0.012), and CONTROL (0.68 ± 0.45, p = 0.005). Fres and R5-R20 were independent IOS predictors of the DI Index. CONCLUSION: The bronchodilating effect is impaired in COUGH and preserved in mild CA, CVA, and CONTROL. Increased peripheral airway resistance and decreased resonant frequency are associated with a decreased DI Index. COUGH is a clinical phenotype distinct from healthy normals and asthma.
RESUMO
The clinical relevance of cough during methacholine challenge in individuals with normal airway sensitivity is unknown. We compared responses of individuals with chronic cough who cough during high-dose methacholine bronchoprovocation and have normal versus increased airway sensitivity to healthy controls. Fifteen healthy participants (CONTROL) aged 26 ± 7 yr (mean ± SD) and 32 participants aged 42 ± 14 yr with chronic cough and suspected asthma completed high-dose methacholine challenge testing. Three participants who did not cough and had normal airway sensitivity were excluded. Spirometry and lung volumes were compared at the maximum response (MAX) among 1) ASTHMA [ n = 15, provocative concentration of methacholine causing a 20% fall in forced expiratory volume in 1 s (FEV1) from baseline (PC20) 4.71 ± 1.37 mg/ml], 2) methacholine-induced cough with normal airway sensitivity (COUGH, n = 14, PC20 41.2 ± 18.7 mg/ml for 3 participants with a measurable PC20), and 3) CONTROL ( n = 15; PC20 93.4 ± 95.4 mg/ml for 4 participants with a measurable PC20). Esophageal pressure-derived pulmonary mechanics were compared at MAX for the ASTHMA and COUGH groups. From baseline to MAX, FEV1 and forced expiratory flow between 25% and 75% of forced vital capacity decreased more in ASTHMA (-36.2 ± 3.8 %pr; -47.1 ± 6.9 %pr, respectively) than COUGH (-12.2 ± 3.0 %pr ( P < 0.001); -24.7 ± 6.5 %pr ( P < 0.001), respectively) and CONTROL (-13.7 ± 2.0 %pr ( P < 0.001); -32.8 ± 5.4 %pr ( P < 0.017), respectively). In both ASTHMA and COUGH, inspiratory capacity decreased by 500-800 ml, and functional residual capacity and residual volume increased by ~800 ml. Individuals with COUGH develop dynamic hyperinflation and gas trapping comparable to individuals with ASTHMA despite less bronchoconstriction and smaller reductions in mid-to-late expiratory flows, which leads us to believe that COUGH is a distinct phenotype. NEW & NOTEWORTHY Healthy individuals and individuals with chronic cough who demonstrate normal airway sensitivity but cough during methacholine bronchoprovocation bronchoconstrict less than individuals with mild asthma. However, those who cough and have normal airway sensitivity develop dynamic hyperinflation and gas trapping comparable to individuals with mild asthma. Thus, methacholine-induced cough with normal airway sensitivity may be clinically relevant, related to reversible small airway obstruction and preservation of the bronchodilating and/or bronchoprotective effects of deep inspirations.
