RESUMEN
OBJECTIVE: Health disparities in lesbian, gay, bisexual, transgender, and queer/questioning (LGBTQ+), or sexual and gender minority (SGM) people are known. SGM people have higher cancer risk, but lower rates of screenings, resulting in a higher likelihood of late-stage disease. This study evaluates medical students' clinical cultural awareness in cancer care of SGM patients to identify gaps in education. METHODS: This was a cross-sectional survey distributed to medical students at a academic center. There were 38 questions on demographics, attitudes, and knowledge of SGM topics. Descriptive statistics were used for demographic information and stratified analyses assessed responses by demographic subgroups. RESULTS: There were 238 responses from 1145 students (response rate = 20.7 %). Of the responders, 91.2 % and 79 % were comfortable treating lesbian, gay, bisexual (LGB) and transgender patients respectively. Only 28.6 % and 21.8 % were confident treating LGB and transgender patients respectively after taking the survey. 91.2 % of students were interested receiving education regarding SGM health needs. CONCLUSION: While most medical students are comfortable treating LGBTQ+ patients, most are not confident in their knowledge. This difference is most profound in knowledge of transgender patients. PRACTICE IMPLICATIONS: Schools must provide more education in SGM topics to improve student knowledge to produce competent providers.
RESUMEN
PURPOSE: Novel CT reconstruction techniques strive to maintain image quality and processing efficiency. The purpose of this study is to investigate the impact of a newer hybrid iterative reconstruction technique, Adaptive Statistical Iterative Reconstruction-V (ASIR-V), in combination with various CT scan parameters on the semi-automated quantification using various lung nodules. METHODS: A chest phantom embedded with eight spherical objects was scanned using varying CT parameters such as tube current and ASIR-V levels. We calculated absolute percentage error (APE) and mean APE (MAPE) using differences between the semi-automated measured diameters and known dimensions. Predictive variables were assessed using a multivariable general linear model. The linear regression slope coefficients (ß) were reported to demonstrate effect size and directionality. RESULTS: The APE of the semi-automated measured diameters was higher in ground-glass than solid nodules (ß = 9.000, p < 0.001). APE had an inverse relationship with nodule diameter (mm; ß = -3.499, p < 0.001) and tube current (mA; ß = -0.006, p < 0.001). MAPE did not vary based on the ASIR-V level (range: 5.7%-13.1%). CONCLUSION: Error is dominated by nodule characteristics with a small effect of tube current. Regardless of phantom size, nodule size accuracy is not affected by tube voltage or ASIR-V level, maintaining accuracy while maximizing radiation dose reduction.

To study whether a diagnosis of cancer affects the clinical presentation and outcomes of patients with pulmonary embolism (PE). A retrospective analysis was performed of all consecutive patients diagnosed with PE on a computed tomography scan from 2014 to 2016 at an urban tertiary-referral medical center. Baseline characteristics, treatment decisions, and mortality data were compared between study subjects with and without a known diagnosis of active cancer. There were 581 subjects, of which 187 (33.0%) had a diagnosis of cancer. On average, cancer subjects tended to be older (64.8 vs. 58.5 years, p < 0.01), had lower body mass index (BMI) (29.0 vs. 31.5 kg/m2, p = 0.01), and were less likely to be active smokers (9.2% vs. 21.1%, p < 0.01), as compared to non-cancer subjects. Cancer subjects were also less likely to present with chest pain (18.2% vs. 37.4%, p < 0.01), syncope (2.7% vs. 6.6%, p = 0.05), bilateral PEs (50% vs. 60%, p = 0.025), and evidence of right heart strain (48% vs. 58%, p = 0.024). There was no difference in-hospital length of stay (8.9 vs. 9.4 days, p = 0.61) or rate of intensive care unit (ICU) admission (31.9% vs. 33.3%, p = 0.75) between the two groups. Presence of cancer increased the risk of all-cause one-year mortality (adjusted HR 9.7, 95% CI 4.8-19.7, p < 0.01); however, it did not independently affect in-hospital mortality (adjusted HR 2.9, 95% CI 0.86-9.87, p = 0.086). Patients with malignancy generally presented with less severe PE. In addition, malignancy did not independently increase the risk of in-hospital mortality among PE patients.

BACKGROUND: Patients with esophageal cancer (EC) have high rates of malnutrition due to tumor location and treatment-related toxicity. Various strategies are used to improve nutritional status in patients with EC including oral and enteral support. METHODS: We conducted a retrospective analysis to determine the impact of malnutrition and prophylactic feeding jejunostomy tube (FJT) placement on toxicity and outcomes in patients with localized EC who were treated with neoadjuvant chemoradiation therapy (nCRT) followed by esophagectomy. RESULTS: We identified 125 patients who were treated with nCRT between 2002 and 2014. Weight loss and hypoalbuminemia occurred frequently during nCRT and were associated with multiple adverse toxicity outcomes including hematologic toxicity, nonhematologic toxicity, grade ≥3 toxicity, and hospitalizations. After adjusting for relevant covariates including the specific nCRT chemotherapy regimen received and the onset of toxicity, there were no significant associations between hypoalbuminemia, weight loss, or FJT placement and relapse-free survival (RFS) or overall survival (OS). FJT placement was associated with less weight loss during nCRT (p = 0.003) but was not associated with reduced toxicity or improved survival. CONCLUSIONS: Weight and albumin loss during nCRT for EC are important factors relating to treatment toxicity but not RFS or OS. While pretreatment FJT placement may reduce weight loss, it may not impact treatment tolerance or survival.

BACKGROUND: Neoadjuvant chemoradiation (nCRT) followed by esophagectomy is the standard treatment for locally advanced esophageal cancer. Older patients are often felt to be poor candidates for nCRT. Limited data is available to guide the use of nCRT in this population. METHODS: A retrospective review of patients treated at a tertiary cancer center between 2002 and 2014 was conducted grouping patients by age (≥ 65 orâ¯<â¯65) for evaluation of differences in toxicity and outcomes. Evaluation of pre-treatment platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) was also performed. Univariate (UVA) and multivariate analyses (MVA) determined associations between age, toxicities and outcomes. The Kaplan-Meier method (KM) assessed overall survival (OS) and relapse free survival (RFS). RESULTS: 125 patients were identified for this study (67 aging <65, and 58â¯≥â¯65). In the UVA, advanced age was only associated with increased hematologic toxicity (pâ¯=â¯.04). After adjusting for covariates in the MVA, there were no significant differences in toxicity between older and younger patients. There were also no differences between overall survival and relapse free survival between age groups. Increased pre-treatment NLR was strongly correlated with advanced age (pâ¯=â¯.01), increased hospitalizations (pâ¯=â¯.04), and decreased RFS (pâ¯=â¯.002). CONCLUSIONS: Older patients who underwent nCRT followed by esophagectomy had similar toxicities and outcomes as younger patients suggesting that nCRT before esophagectomy is safe in select older adults with esophageal cancer. PLR and NLR may serve as prognostic markers of aging, toxicity, and outcomes. Further research is warranted to optimize the therapy of older patients with this disease.
