RESUMEN

Shigellosis is a gastrointestinal infection caused by species of Shigella. A large outbreak of Shigella flexneri serotype 2a occurred in Albuquerque, New Mexico (NM) between May 2021 and November 2023 that involved humans and nonhuman primates (NHP) from a local zoo. We analyzed the genomes of 202 New Mexico isolates as well as 15 closely related isolates from other states, and four from NHP. The outbreak was initially detected within men who have sex with men (MSM) but then predominantly affected people experiencing homelessness (PEH). Nearly 70% of cases were hospitalized and there was one human death. The outbreak extended into Albuquerque's BioPark Zoo, causing high morbidity and six deaths in NHPs. The NHP isolates were identical to those in the human outbreak. All isolates were multidrug-resistant, including towards fluoroquinolones, a first line treatment option which led to treatment failures in human and NHP populations. We demonstrate the transmission of this S. flexneri strain between humans and NHPs, causing fatalities in both populations. This study demonstrates the threat of antimicrobial resistant organisms to vulnerable human and primate populations and emphasizes the value of vigilant genomic surveillance within a One Health framework.

RESUMEN

Importance: Women account for only 28% of current US medical school deans. Studying the differences between women and men in their preparation to becoming deans might help to explain this discrepancy. Objective: To identify differences in the leadership development experiences between women and men in their ascent to the medical school deanship. Design, Setting, and Participants: In this qualitative study, volunteers from the roster of the Association of American Medical Colleges Council of Deans were solicited and interviewed from June 15 to November 9, 2023. Women deans were recruited first, then men who had been appointed to their deanships at a similar time to their women counterparts were recruited. Deans were interviewed on topics related to number of applications for deanships, prior leadership roles, leadership development, personal factors, and career trajectories. Interviews were coded, and themes were extracted through conventional content analysis. Main Outcome and Measures: Career and leadership development experiences were elicited using a semistructured interview guide. Results: We interviewed 17 women and 17 men deans, representing 25.8% (34 of 132) of the total population of US medical school deans. Most deans (23 [67.6%]) practiced a medicine-based specialty or subspecialty. No statistically significant differences were found between women and men with regard to years to attain deanship (mean [SD], 2.7 [3.4] vs 3.7 [3.7] years), years as a dean (mean [SD], 5.7 [5.2] vs 6.0 [5.0] years), highest salary during career (mean [SD], $525 769 [$199 936] vs $416 923 [$195 848]), or medical school rankings (mean [SD], 315.5 [394.5] vs 480.5 [448.9]). Their reports indicated substantive gender differences in their paths to becoming a dean. Compared with men, women deans reported having to work harder to advance, while receiving less support and opportunities for leadership positions by their own institutions. Subsequently, women sought leadership development from external programs. Women deans also experienced gender bias when working with search firms. Conclusions and Relevance: This qualitative study of US medical school deans found that compared with men, women needed to be more proactive, had to participate in external leadership development programs, and had to confront biases during the search process. For rising women leaders, this lack of support had consequences, such as burnout and attrition, potentially affecting the makeup of future generations of medical school deans. Institutional initiatives centering on leadership development of women is needed to mitigate the gender biases and barriers faced by aspiring women leaders.

RESUMEN

School closures in March 2020 due to the COVID-19 pandemic precipitated losses of critical student resources as physical, mental, emotional, and social needs escalated. Identifying the challenges, strategies, and changes in school nurse (SN) practice in Massachusetts during this pandemic is fundamental to understanding how to manage future anticipated pandemics while protecting children, communities, and SNs. The purpose of this mixed-methods descriptive study in the second year of the global pandemic was to (a) listen to SN voices through a novel online survey including the prompts of challenges, strategies, and practice changes and (b) describe the SN experience of COVID-19 response in Massachusetts schools, including identification of intent to leave school nursing. Responses were analyzed using descriptive qualitative analysis (n = 73). The prompts each elicited subthemes that coalesced to a cohesive theme: Finding one's way required the support of others to pave untraversed roads.

RESUMEN

PURPOSE: Locoregionally advanced HPV+ oropharyngeal squamous cell carcinoma (OPSCC) has excellent cure rates, although current treatment regimens are accompanied by acute and long-term toxicities. We designed a phase II deescalation trial for patients with HPV+ OPSCC to evaluate the feasibility of an upfront neck dissection to individualize definitive treatment selection to improve the quality of life without compromising survival. PATIENTS AND METHODS: Patients with T1-3, N0-2 HPV+ OPSCC underwent an upfront neck dissection with primary tumor biopsy. Arm A included patients with a single lymph node less than six centimeters, with no extracapsular spread (ECS) and no primary site adverse features underwent transoral surgery. Arm B included patients who had two or more positive lymph nodes with no ECS, or those with primary site adverse features were treated with radiation alone. Arm C included patients who had ECS in any lymph node and were treated with chemoradiation. The primary endpoint was quality of life at 1 year compared with a matched historical control. RESULTS: Thirty-four patients were enrolled and underwent selective neck dissection. On the basis of pathologic characteristics, 14 patients were assigned to arm A, 10 patients to arm B, and 9 to arm C. A significant improvement was observed in Head and Neck Quality of Life (HNQOL) compared with historical controls (-2.6 vs. -11.9, P = 0.034). With a median follow-up of 37 months, the 3-year overall survival was 100% and estimated 3-year estimated progression-free survival was 96% [95% confidence interval (CI), 76%-99%]. CONCLUSIONS: A neck dissection-driven treatment paradigm warrants further research as a deintensification strategy.

RESUMEN

Shigella flexneri is a nonmotile gram-negative bacillus that affects humans and nonhuman primates. In August 2021, 15 primates at the ABQ BioPark demonstrated clinical signs of Shigella infection: 3 out of 4 Sumatran and hybrid orangutans (Pongo abelii), 6 out of 8 gorillas (Gorilla gorilla), 2 out of 9 chimpanzees (Pan troglodytes), and 4 out of 4 siamangs (Hylobates syndactylus). Three siamangs and one gorilla succumbed to complications of shigellosis during the initial outbreak and a chimpanzee died 10 mon later. Although it is well documented that Shigella may cause morbidity and mortality in nonhuman primates, the rapid and devastating nature of the outbreak, the difference from previous reports in zoological collections (enzootic vs outbreak), and the chronological overlap with the increase in human cases in the region makes discussion of this Shigella outbreak of significance. The cases presented here are significantly different than previous reports, because these were part of an outbreak that arose and subsided, versus other reports where the authors describe an enzootic disease with persistently infected animals. Close communication with the New Mexico Department of Health allowed for the investigation into possible sources of the outbreak, recommendations regarding biosecurity protocols, and staff education.

RESUMEN

Importance: Historical data reveal that, compared with women, men are more likely to pursue a head and neck surgical oncology fellowship, but little is known about possible gender differences in academic productivity. Objective: To assess demographic trends and academic productivity among American Head & Neck Society (AHNS) fellowship graduates. Design, Setting, and Participants: This cross-sectional study used electronically published data from the AHNS on fellowship graduates in the US and Canada from July 1, 1997, to June 30, 2022. Scopus was used to extract h-indices for each graduate. Exposure: Scholarly activity. Main Outcomes and Measures: Main outcomes were changes in demographic characteristics and academic productivity among AHNS graduates over time. Data analysis included effect size, η2, and 95% CIs. Results: A total of 691 AHNS fellowship graduates (525 men [76%] and 166 women [24%]) were included. Over the study period, there was an increase in the number of programs offering a fellowship (η2, 0.84; 95% CI, 0.68-0.89) and an increase in the absolute number of women who completed training (η2, 0.66; 95% CI, 0.38-0.78). Among early-career graduates pursuing an academic career, there was a small difference in the median h-index scores between men and women (median difference, 1.0; 95% CI, -1.1 to 3.1); however, among midcareer and late-career graduates, there was a large difference in the median h-index scores (midcareer graduates: median difference, 4.0; 95% CI, 1.2-6.8; late-career graduates: median difference, 6.0; 95% CI, 1.0-10.9). A higher percentage of women pursued academic positions compared with men (106 of 162 [65.4%] vs 293 of 525 [55.8%]; difference, 9.6%; 95% CI, -5.3% to 12.3%). Conclusions and Relevance: This cross-sectional study suggests that women in head and neck surgery begin their careers with high levels of academic productivity. However, over time, a divergence in academic productivity between men and women begins to develop. These data argue for research to identify possible reasons for this observed divergence in academic productivity and, where possible, develop enhanced early faculty development opportunities for women to promote their academic productivity, promotion, and advancement into leadership positions.

RESUMEN

Importance: Sponsorship, distinct from mentorship or coaching, involves advancing the careers of individuals by nominating them for roles, increasing the visibility of their work, or facilitating opportunities. Sponsorship can open doors and enhance diversity; however, achieving desirable outcomes requires equitable approaches to cultivating potential in sponsees and promoting their success. The evidence on equitable sponsorship practices has not been critically examined, and this special communication reviews the literature, highlighting best practices. Observations: Sponsorship addresses an unmet need for supporting individuals who have historically been afforded fewer, less visible, or less effective opportunities for upward career mobility. Barriers to equitable sponsorship include the paucity of sponsors of underrepresented identity; smaller and underdeveloped networks among these sponsors; lack of transparent, intentional sponsorship processes; and structural inequities that are associated with recruitment, retention, and advancement of diverse individuals. Strategies to enhance equitable sponsorship are cross-functional, building on foundational principles of equity, diversity, and inclusion; patient safety and quality improvement; and insights from education and business. Equity, diversity, and inclusion principles inform training on implicit bias, cross-cultural communication, and intersectional mentoring. Practices inspired by patient safety and quality improvement emphasize continuously improving outreach to diverse candidates. Education and business insights emphasize minimizing cognitive errors, appreciating the bidirectional character of interactions, and ensuring that individuals are prepared for and supported in new roles. Collectively, these principles provide a framework for sponsorship. Persistent knowledge gaps are associated with timing, resources, and systems for sponsorship. Conclusions and Relevance: The nascent literature on sponsorship is limited but draws on best practices from various disciplines and has potential to promote diversity within the profession. Strategies include developing systematic approaches, providing effective training, and supporting a culture of sponsorship. Future research is needed to define best practices for identifying sponsees, cultivating sponsors, tracking outcomes, and fostering longitudinal practices that are sustainable at local, regional, and national levels.

RESUMEN

Head and neck cancer (HNC) is the seventh most common malignancy, with oropharyngeal squamous cell carcinoma (OPSCC) accounting for a majority of cases in the western world. While HNC accounts for only 5% of all cancers in the United States, the incidence of a subset of OPSCC caused by human papillomavirus (HPV) is increasing rapidly. The treatment for OPSCC is multifaceted, with a recently emerging focus on immunotherapeutic approaches. With the increased incidence of HPV-related OPSCC and the approval of immunotherapy in the management of recurrent and metastatic HNC, there has been rising interest in exploring the role of immunotherapy in the treatment of HPV-related OPSCC specifically. The immune microenvironment in HPV-related disease is distinct from that in HPV-negative OPSCC, which has prompted further research into various immunotherapeutics. This review focuses on HPV-related OPSCC, its immune characteristics, and current challenges and future opportunities for immunotherapeutic applications in this virus-driven cancer.

RESUMEN

BACKGROUND: We sought to characterize early changes in CD8+ tumor-infiltrating lymphocytes and tumor transcriptomes after induction cetuximab in a cohort with p16-positive oropharyngeal cancer on a phase II clinical de-escalation trial. METHODS: Tumor biopsies were obtained before and 1 week after a single cetuximab loading dose in eight patients enrolled in a phase II trial of cetuximab and radiotherapy. Changes in CD8+ tumor-infiltrating lymphocytes and transcriptomes were assessed. RESULTS: One week after cetuximab, five patients (62.5%) had an increase in CD8+ cell infiltration with a median (range) fold change of +5.8 (2.5-15.8). Three (37.5%) had unchanged CD8+ cells (median [range] fold change of -0.85 [0.8-1.1]). In two patients with evaluable RNA, cetuximab induced rapid tumor transcriptome changes in cellular type 1 interferon signaling and keratinization pathways. CONCLUSIONS: Within 1 week, cetuximab induced measurable changes in pro-cytotoxic T-cell signaling and immune content.

RESUMEN

OBJECTIVE: To explore challenges and opportunities for supporting midcareer women otolaryngologists in the areas of negotiation and sponsorship. STUDY DESIGN: Qualitative approach using semistructured interviews. SETTING: Online multi-institutional interviews. METHODS: This study was performed from June to August 2021. Women otolaryngologists representing diverse subspecialties, training, and practice environments were recruited via a purposive criterion-based sampling approach. Semistructured interviews were transcribed, coded, and analyzed via an inductive-deductive approach to produce a thematic content analysis. RESULTS: Among the 12 women interviewees, who represented 7 subspecialties, the majority were Caucasian (58%) and in academic practice (50%). The median residency graduation year was 2002 (range, 1982-2013). Participants expressed several challenges that women otolaryngologists face with respect to negotiation, including the absence of systematic formal negotiation training, gendered expectations that women experience during negotiations, and a perceived lack of power in negotiations. Obstacles to effective sponsorship included difficulty in the identification of sponsors and the influence of gender and related systemic biases that hindered sponsorship opportunities. CONCLUSION: Notable gender disparities exist for negotiation and sponsorship in the midcareer stage for women otolaryngologists. Women start at a disadvantage due to a lack of negotiation training and access to sponsors, which is exacerbated by systemic gender bias and power differentials as women advance in their careers. This study highlights opportunities to improve negotiation and sponsorship for women, with the goal of promoting a more diverse workforce.

RESUMEN

Objective: Although parenting responsibilities are correlated with gender disparities in professional development and salary, the nature of parental challenges is not well characterized. The aims of this study were to (1) illuminate faculty physicians' experiences with parenting and (2) identify system challenges and opportunities for improvement. Materials and Methods: In October 2019, a survey about parenting was sent to all physician faculty at a large Midwest academic medical center. Qualitative analysis of free-text response to the survey item "is there anything you wish to share about your experience of pregnancy or parenting as a physician" was performed. Themes were inductively identified and developed from the responses in a team-based iterative approach. Results: Of 2069 total physician faculty, 1085 (52.4%) responded to the survey and 253 (23%) of the respondents provided free-text comments. From these comments, the authors identified three themes as sources of challenges for physician parents: operational constraints, gender biases, and nontraditional or nonheteronormative family structures. Operational factors pertained to lack of scheduling flexibility, childcare challenges, lactation, colleague coverage, and transparency of policies. Responses indicated that gender biases are encountered by all genders, and expectations built on assumptions of "traditional" gender roles and family structure are problematic for many physician parents. Conclusion: Addressing the challenges and opportunities identified in the study is critical to building a more supportive institutional culture around parenting and to increase gender parity in academic medicine.

RESUMEN

BACKGROUND: Single cycle induction chemotherapy (IC) with platinum and 5-flurouracil (PF) and treatment based on clinical response predicts organ preservation in laryngeal cancer. Other agents offer intriguing alternatives with potentially increased ease of administration, reduced risk for severe toxicities, and increased platinum sensitivity. METHODS: We report the results of a phase II bioselection trial in advanced resectable laryngeal cancer utilizing an IC regimen of two cycles of platinum plus docetaxel (TP) with a Bcl-2 inhibitor. The primary endpoint was organ preservation rate at 12 weeks post chemoradiation. RESULTS: Fifty-four patients were enrolled. Response to IC was 72%. The organ preservation rate was 59% with a laryngectomy free survival of 46%. Induction related grade ≥3 toxicities were observed in 56% of patients with two grade 5 events. CONCLUSIONS: Two cycles of TP IC plus a Bcl-2 inhibitor did not improve laryngeal preservation compared to a single cycle of PF.

RESUMEN

Our objective was to identify the upper ambient temperature threshold that triggers an increase in cortisol in response to increased thermoregulatory demands in polar bears. The results reported here include endocrine data collected over two years from 25 polar bears housed in 11 accredited zoological institutions across North America. The effects of ambient temperature, sex, age group (juvenile, adult, elderly), breeding season and humidity on fecal cortisol metabolite (FCM) concentrations (N = 8439 samples) were evaluated using linear mixed models. Ambient temperatures were placed into five different categories: <5 °C, 6−10 °C, 11−15 °C, 16−20 °C, and >20 °C. Ambient temperature and humidity had a significant (p < 0.05) effect on FCM concentrations with significant (p < 0.05) interactions of sex, age and breeding season. Once biotic factors were accounted for, there was a significant (p < 0.05) increase in FCM concentrations associated with ambient temperatures above 20 °C in adult polar bears. The implications of these findings for the management of both zoo and wild polar bears are discussed.

RESUMEN

Head and neck squamous cell carcinomas (HNSCCs) arising in the mucosal linings of the upper aerodigestive tract are highly heterogeneous, aggressive, and multifactorial tumors affecting more than half a million patients worldwide each year. Classical etiological factors for HNSCC include alcohol, tobacco, and human papillomavirus (HPV) infection. Current treatment options for HNSCCs encompass surgery, radiotherapy, chemotherapy, or combinatorial remedies. Comprehensive integrative genomic analysis of HNSCC has identified mutations in TP53 gene as the most frequent of all somatic genomic alterations. TP53 mutations are associated with either loss of wild-type p53 function or gain of functions that promote invasion, metastasis, genomic instability, and cancer cell proliferation. Interestingly, disruptive TP53 mutations in tumor DNA are associated with aggressiveness and reduced survival after surgical treatment of HNSCC. This review summarizes the current evidence and impact of TP53 mutations in HNSCC.

RESUMEN

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is a debilitating disease with poor survival. Although epidermal growth factor receptor (EGFR)-targeting antibody cetuximab improves survival in some settings, responses are limited suggesting that alternative approaches are needed. METHODS: We performed a high throughput drug screen to identify EGFR inhibitor-based synergistic combinations of clinically advanced inhibitors in models resistant to EGFR inhibitor monotherapies, and then performed downstream validation experiments on prioritized synergistic combinations. RESULTS: From our screen, we re-discovered known synergistic EGFR inhibitor combinations with FGFR or IGF-1R inhibitors that were broadly effective and also discovered novel synergistic combinations with XIAP inhibitor and DNMT inhibitors that were effective in only a subset of models. CONCLUSIONS: Conceptually, our data identify novel synergistic combinations that warrant evaluation in future studies, and suggest that some combinations, although highly synergistic, will require parallel companion diagnostic development to be effectively advanced in patients.

RESUMEN

BACKGROUND AND PURPOSE: Bioselection with induction chemotherapy in larynx cancer is associated with excellent larynx preservation and disease-specific survival but requires visual inspection of the primary tumor. We retrospectively compare clinical and imaging response in bioselected patients to develop predictive models of surgeon-assessed response (SR), laryngectomy-free survival (LFS), and overall survival (OS) in bioselected patients. MATERIALS AND METHODS: In a secondary analysis of patients on two single-institution bioselection trials, model building used a regularized regression model (elastic-net) and applied nested cross-validation. Logistic regression-based model was used to predict SR and Cox proportional hazard-based models were used to predict LFS and OS. RESULTS: In 115 patients with a median age of 57 years, most patients had supraglottic tumors (73.0%) and T3/T4 disease (94.8%). Definitive treatment was chemoradiation in 76.5% and laryngectomy in 23.5%. Change in primary tumor (OR = 5.78, p < 0.001) and N-classification (OR = 1.64, p = 0.003) predicted SR (AUC 0.847). Change in tumor volume (HR = 0.58, p < 0.001) predicted LFS (c-index 0.724). N-classification (HR = 1.48, p = 0.04) and pre-chemotherapy tumor volume (HR = 1.30, p = 0.174) predicted OS (c-index 0.552). CONCLUSIONS: Imaging offers a non-invasive opportunity to evaluate response to induction chemotherapy, complementary to surgeon assessment. Further evaluation of approaches to bioselection that optimize generalizability of this paradigm are needed, and clinical trials utilizing imaging to predict outcomes including LFS are warranted.

RESUMEN

OBJECTIVE: Recent randomized data suggest that completion lymph node dissection after a positive sentinel lymph node biopsy (SLNB) improves locoregional control but does not improve survival for melanoma patients. Locoregional recurrences of head and neck cutaneous melanoma (HNCM) may result in significant morbidity. A better understanding of morbidity is thus important to inform decisions about whether to pursue completion neck dissection (ND). STUDY DESIGN: Cross-sectional study. SETTING: Academic tertiary care hospital. METHODS: Clinical data were collected for patients with HNCM seen between 2016 and 2019 who were at least 1-year disease free. Each patient completed the Self-administered Leeds Assessment of Neuropathic Symptoms and Signs (SLANSS), Neck Dissection Impairment Index, and SF-36 (Short Form-36). Scores were compared by surgical treatment: wide local excision (WLE) only, SLNB, and ND. Univariate and multivariable regression was performed. RESULTS: Of 474 patients, 140 returned questionnaires (29.5% response rate; WLE, n = 49; SLNB, n = 76; ND, n = 15). No significant differences in SLANSS or Neck Dissection Impairment Index scores were found between the WLE and SLNB groups. SLANSS scores differed by 2 SD (P = .001) in the ND cohort, which had a 36% rate of neuropathy. Neck impairment was worse by 1 SD (P = .01) in the ND cohort. No differences were found in SF-36 domains. CONCLUSION: Neuropathy and neck impairment are components of morbidity after ND. These risks must be balanced with potential morbidity of locoregional recurrence in HNCM.

RESUMEN

At the foundation of clinical medicine is the relationship among patients, families, and health care professionals. Implicit to that social contract, professionals pledge to bring clinical excellence to advance their patients' wellness and healing-and to prevent harm. Patients trust that those privileged to deliver care will do so unwaveringly in service of patients' best interests; however, the incentives and infrastructure surrounding health care delivery can promote or undermine individual performance, teamwork, and patient safety. Modeling professionalism and identifying slips and lapses supports pursuit of high reliability. Part 1, Promoting Professionalism, introduces the first of 3 pillars of advancing the clinical mission.

RESUMEN

When patients are harmed by health care, concerns fan out in all directions. Patients and families confront a sea of uncertainty, contending with injuries that drain them physically, emotionally, and financially. Health care professionals experience a powerful mix of emotions, but are seldom afforded the time to process what happened or the resources to relieve suffering and prevent harm. Honesty, transparency, and empathy are indispensable to a comprehensive approach that prioritizes patient and family-centered response to unintended harm, clinical improvement, and redemptive peer review. Part 2 introduces the second of three pillars for advancing the clinical mission: communication and transparency.

RESUMEN

The hidden epidemic of burnout exacts a staggering toll on professionals and patients, reflected in increased risk of medical errors, complications, and staff turnover. For surgeons, nurses, and other team members working at the sharp end of care, adverse events can amplify work exhaustion, interpersonal disengagement, and risk of moral adversity. Visionary leaders are not content to mitigate burnout and moral injury; they elevate the human experience throughout health care by modeling wellness, fostering moral courage, promoting safety of professionals, and restoring joy in work. Part 3, Health Professional Wellness and Resilience, introduces the final pillar for advancing the clinical mission.
