ABSTRACT
OBJECTIVES: Laryngeal and hypopharyngeal cancers treated with total laryngectomy (TL) may provide a unique avenue for COVID-19 to infect cancer patients. The objective of this investigation was to identify incidence of COVID-19 infection and potential complications in TL patients. MATERIALS AND METHODS: Data was extracted from TriNetX COVID-19 research network from from 2019 to 2021 and ICD-10 codes were utilized to query for laryngeal or hypopharyngeal cancer, and outcomes of interest. Cohorts were propensity score-matched based on demographics and co-morbidities. RESULTS: A query of active patients in TriNetX from January 1, 2019 to December 31, 2021 identified 36,414 patients with laryngeal or hypopharyngeal cancer out of the 50,474,648 active patients in the database. The overall COVID-19 incidence in the non-laryngeal or hypopharyngeal cancer population was 10.8% compared to 18.8% (p < 0.001) in the laryngeal and hypopharyngeal cancer group. Those who underwent TL had a statistically significant increased incidence of acquiring COVID-19 (24.0%) when compared to those without TL (17.7%) (p < 0.001). TL patients with COVID-19 had a higher risk of developing pneumonia RR (risk ratio) 1.80 (1.43, 2.26), death 1.74 (1.41, 2.14), ARDS 2.42 (1.16, 5.05), sepsis 1.77 (1.37, 2.29), shock 2.81 (1.88, 4.18), respiratory failure 2.34 (1.90, 2.88), and malnutrition 2.46 (2.01, 3.01) when matched with those COVID-19 positive cancer patients without TL. CONCLUSIONS: Laryngeal and hypopharyngeal cancer patients had a higher rate of acquiring COVID-19 than patients without these cancers. TL patients have a higher rate of COVID-19 compared to those without TL and may be at a higher risk for sequalae of COVID-19.

BACKGROUND: Rising healthcare costs have emphasized the need to teach cost-conscious care in graduate medical education. OBJECTIVE: To teach high-value care and diagnostic evaluation of pediatric musculoskeletal complaints to residents and rotating medical students through online cases. METHODS: Six online cases were developed and tested at the University Hospitals Cleveland Medical Center. Learners completed modules in one of two groups, those who saw itemized costs of diagnostic tests or those who did not. All learners completed a post-simulation survey. Measured outcomes included presumed diagnosis, cost of evaluation, tests ordered, and perceptions toward high-value care. Simulation outcomes were assessed using paired t-tests. Survey data was analyzed with Chi-squared tests. Outcomes separated by training year were analyzed using ANOVA and post-hoc Tukey test. RESULTS: Thirty-nine residents and medical students participated and were randomly assigned to complete the cases with costs (n = 19) or no costs (n = 20) displayed during workup. Overall, learners who saw costs spent less money on diagnostics ($1511.11 mean per learner versus $2311.35, p = 0.01). Arrival at the correct diagnosis was associated with lower costs in 3 of 6 cases. When compared to the no cost group, learners in the costs group reported feeling more knowledgeable about the price of diagnostic tests (p = 0.04) and were more likely to factor costs into their practice moving forward (p = 0.03). Third year or above residents demonstrated a statically significant increase in correctly diagnosed cases as opposed to medical students. CONCLUSIONS: Interventions that challenge learners to integrate costs into decision-making can potentially change future practice.
ABSTRACT
PURPOSE: The purpose of this work is to explore audiometry following cochlear implantation (CI) in patients with enlarged vestibular aqueduct (EVA) and to investigate the effects of inner ear morphological variation on post CI audiometry. METHODS: This was a retrospective review of both natural and cochlear-implant-aided audiometry results, using all available measurements in a mixed-effects model accounting for longitudinal change and the grouping structure of ears. Patients who visited our tertiary academic medical center between 2000 and 2016 were identified as having EVA according to Cincinnati criteria on radiological examination; patients eligible for CI were then selected for analysis. RESULTS: Multivariable modeling showed a statistically significant hearing improvement in ears with EVA undergoing CI with regards to pure tone average (-64.0â¯dB, pâ¯<â¯0.0001), speech reception threshold (-57.90â¯dB, pâ¯<â¯0.0001), and word score (34.8%, pâ¯>â¯0.0001). Vestibular aqueduct midpoint size and the presence of incomplete partition type II (IP II) did not have significant independent associations with audiometric findings. However, multivariable modeling revealed a statistically significant interaction between IP II and CI such that IP II ears demonstrated a decrease in WS improvement of 30.2% (pâ¯=â¯0.0059) compared to non-IP II ears receiving CI. CONCLUSION: There is a statistically significant audiometric benefit to ears with EVA receiving CI. Morphology, specifically the presence of IP II, may hinder CI benefit in terms of word score however this finding needs clinical validation. This data improves personalization of surgical counseling and planning for patients with EVA considering CI.

BACKGROUND: Disparities in access to colorectal cancer care are multifactorial and are affected by socioeconomic elements. Uninsured and Medicaid patients present with advanced stage disease and have worse outcomes compared with similar privately insured patients. Safety net hospitals are a major care provider to this vulnerable population. Few studies have evaluated outcomes for safety net hospitals compared with private institutions in colorectal cancer. OBJECTIVE: The purpose of this study was to compare demographics, screening rates, presentation stage, and survival rates between a safety net hospital and a tertiary care center. DESIGN: Comparative review of patients at 2 institutions in the same metropolitan area were conducted. SETTINGS: The study included colorectal cancer care delivered either at 1 safety net hospital or 1 private tertiary care center in the same city from 2010 to 2016. PATIENTS: A total of 350 patients with colorectal cancer from each hospital were evaluated. MAIN OUTCOME MEASURES: Overall survival across hospital systems was measured. RESULTS: The safety net hospital had significantly more uninsured and Medicaid patients (46% vs 13%; p < 0.001) and a significantly lower median household income than the tertiary care center ($39,299 vs $49,741; p < 0.0001). At initial presentation, a similar percentage of patients at each hospital presented with stage IV disease (26% vs 20%; p = 0.06). For those undergoing resection, final pathologic stage distribution was similar across groups (p = 0.10). After a comparable median follow-up period (26.6 mo for safety net hospital vs 29.2 mo for tertiary care center), log-rank test for overall survival favored the safety net hospital (p = 0.05); disease-free survival was similar between hospitals (p = 0.40). LIMITATIONS: This was a retrospective review, reporting from medical charts. CONCLUSIONS: Our results support the value of safety net hospitals for providing quality colorectal cancer care, with survival and recurrence outcomes equivalent or improved compared with a local tertiary care center. Because safety net hospitals can provide equivalent outcomes despite socioeconomic inequalities and financial constraints, emphasis should be focused on ensuring that adequate funding for these institutions continues.

BACKGROUND: Increasingly, patients with multiple co-morbidities undergo surgery for rectal cancer. We aimed to evaluate if decreased psoas muscle area and volume, as measures for sarcopenia, were associated with postoperative morbidity. METHODS: Retrospective review of patients undergoing rectal cancer resection at a tertiary medical center (2007-2015). Variables included demographics, co-morbidities, preoperative psoas muscle area and volume, and postoperative complications. RESULTS: Among 180 patients (58% male, mean age 62.7 years), 44% experienced complications (n = 79), of which 38% (n = 30) were major complications. Malnourished patients had smaller height-adjusted total psoas area than non-malnourished patients (6.4 vs. 9.5 cm2/m2, p = 0.004). Among patients with imaging obtained within 90 days of surgery, major morbidity was associated with smaller total psoas area (6.7 vs. 10.5 cm2/m2, p = 0.04) and total psoas volume (26.7 vs. 42.2 cm3/m2, p = 0.04) compared to those with minor complications. CONCLUSION: Preoperative cross-sectional imaging may help surgeons anticipate postoperative complications following rectal cancer surgery.

BACKGROUND: Extraneuronal levels of the neurotransmitter glutamate in brain rise during aging. This is thought to lead to synaptic dysfunction and neuronal injury or death. To study the effects of glutamate hyperactivity in brain, we created transgenic (Tg) mice in which the gene for glutamate dehydrogenase (Glud1) is over-expressed in neurons and in which such overexpression leads to excess synaptic release of glutamate. In this study, we analyzed whole genome expression in the hippocampus, a region important for learning and memory, of 10 day to 20 month old Glud1 and wild type (wt) mice. RESULTS: During development, maturation and aging, both Tg and wt exhibited decreases in the expression of genes related to neurogenesis, neuronal migration, growth, and process elongation, and increases in genes related to neuro-inflammation, voltage-gated channel activity, and regulation of synaptic transmission. Categories of genes that were differentially expressed in Tg vs. wt during development were: synaptic function, cytoskeleton, protein ubiquitination, and mitochondria; and, those differentially expressed during aging were: synaptic function, vesicle transport, calcium signaling, protein kinase activity, cytoskeleton, neuron projection, mitochondria, and protein ubiquitination. Overall, the effects of Glud1 overexpression on the hippocampus transcriptome were greater in the mature and aged than the young. CONCLUSIONS: Glutamate hyperactivity caused gene expression changes in the hippocampus at all ages. Some of these changes may result in premature brain aging. The identification of these genomic expression differences is important in understanding the effects of glutamate dysregulation on neuronal function during aging or in neurodegenerative diseases.
