BackgroundBreast conserving surgery represents the preferred surgical treatment option for patients with early-stage breast cancer. Reexcision rates are generally higher for patients undergoing lumpectomies for ductal carcinoma in situ (DCIS) compared to invasive breast cancer, as the microscopic extent of disease is difficult to assess during excision. This study investigated the clinicopathological characteristics of patients undergoing BCS for pure DCIS and reexcision rates over time, including the effect of the MarginProbe™ device.MethodsWe queried our prospectively maintained Institutional Breast Cancer Database for patients diagnosed with DCIS and treated with BCS as their primary procedure from 2010-2021. The primary endpoint was the rate of reexcision. Variables of interest included age at diagnosis, race/ethnicity, mode of diagnostic imaging, mammographic breast density, method of core biopsy, nuclear grade, size of DCIS, multifocality, DCIS subtype, and MarginProbe™ use.ResultsPapillary DCIS (P < 0.004) and larger size (P < 0.001) was associated with an increased reexcision rate. There were also differences in the method of core biopsy (P < 0.001), with stereotactic core biopsy predominating among patients who did not require reexcision (71.3% vs 49.5%). In an unadjusted estimate for the odds ratio for association, patients who had MarginProbe™ used were 81% less likely to require reexcision (OR = 0.19, 95% CI = 0.12, 0.31, P < 0.0001).ConclusionYounger age, papillary DCIS, larger DCIS size, and non-stereotactic core biopsy method were found to be associated with higher reexcision rates. Additionally, patients whose primary procedures included intraoperative margin assessment with the MarginProbe™ were significantly less likely to require reexcision.

BACKGROUND:Current guidelines recommend the resection of main duct- (MD) and mixed-type (MT) intraductal papillary mucinous neoplasms (IPMN) based on specific risk criteria to prevent or treat pancreatic cancer in selected patients. This paradigm follows high rates of malignancy observed in published surgical series. The aim of this systematic review and meta-analysis was to provide robust, pooled rates of invasive carcinoma (IC) and high-grade dysplasia (HGD) in resected MD- and MT-IPMNs of the pancreas. METHODS:The PubMed, Embase, Scopus, Web of Science, and Cochrane CENTRAL databases were systematically searched. Studies that reported rates of IC or HGD, diagnosed by histopathology of surgical specimens, in MD- or MT-IPMNs were included. Pooled prevalence with 95 % confidence interval (95 % CI) was calculated using a random effects model. Galbraith plots were used to evaluate heterogeneity. Risk of bias was assessed using the National Institutes of Health Quality Assessment Tool. RESULTS:Based on 51 studies, 59 % (95 % CI: 54 %, 64 %) of resected MD- and MT-IPMN had IC or HGD, with IC in up to 39 % (95 % CI: 33 %, 44 %) of lesions and HGD in 20 % (95 % CI: 16 %, 25 %). Most studies were deemed to be of good quality and Galbraith plots demonstrated high concordance. CONCLUSIONS:These results confirm the rates of IC and HGD in resected MD/MT-IPMNs. However, a significant proportion of patients have benign lesions, and future research is needed to develop precise diagnostics to distinguish between patients with and without high-risk or cancerous disease.

BACKGROUND:Despite fall-related injuries accounting for over two-thirds of older adult trauma injuries, fall-related injuries are more likely to be under-triaged. The Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA) is an injury risk-triage tool. This study aims to validate STTGMA's accuracy in predicting fall-related mortality among older adult trauma patients and compare its predictive accuracy with the Geriatric Trauma Outcome Score (GTOS) and the Revised Trauma Score (RTS). METHODS:Using a retrospective cohort design, we selected 6,458 older adult trauma patients (aged 65 years and older) from a single institutional trauma database (2017-2023). The primary outcome variable was in-hospital death, measured as a binary variable. The primary predictor variable was the STTGMA score, measured as a continuous variable and a four-level categorical variable. The secondary predictor variables were the GTOS and the RTS. We compared the predictive accuracy (95% confidence interval (CI)) of the STTGMA, GTOS, and RTS. We further assessed the relationships between the STTGMA risk categories and time-to-death and hospital length of stay using multivariable time-varying Cox proportional hazard analysis and multivariable quantile regression analysis, respectively. RESULTS:A total of 130 patients (2.0%) died during admission, and the median hospital length of stay was 2 days. STTGMA exhibited 84% (95% CI: 77.3-89.8) accuracy in predicting in-hospital fall-related mortality, while the GTOS and RTS both exhibited 71% diagnostic accuracies. Compared to the minimal risk category, older adult trauma patients classified as low, moderate, and high risks each had significantly longer hospital stays and adjusted mortality risks, in a dose-response pattern. CONCLUSION/CONCLUSIONS:STTGMA can accurately predict in-hospital mortality and risk-stratify the length of stay and the time to death among older adult trauma patients with fall-related injuries.

BACKGROUND:Pre-injury frailty among older adults with trauma injuries is a predictor of increased morbidity and mortality. OBJECTIVES/OBJECTIVE:We sought to determine the relationship between frailty status and the care trajectories of older adult patients who underwent frailty screening in the emergency department (ED). METHODS:Using a retrospective cohort design, we pooled trauma data from a single institutional trauma database from August 2020 to June 2023. We limited the data to adults 65 years and older, who had trauma injuries and frailty screening at ED presentation (N = 2,862). The predictor variable was frailty status, measured as either robust (score 0), pre-frail (score 1-2), or frail (score 3-5) using the FRAIL index. The outcome variables were measures of clinical care trajectory: trauma team activation, inpatient admission, ED discharge, length of hospital stay, in-hospital death, home discharge, and discharge to rehabilitation. We controlled for age, sex, race/ethnicity, health insurance type, body mass index, Charlson Comorbidity Index, injury type and severity, and Glasgow Coma Scale score. We performed multivariable logistic and quantile regressions to measure the influence of frailty on post-trauma care trajectories. RESULTS:The mean (SD) age of the study population was 80 (8.9) years, and the population was predominantly female (64%) and non-Hispanic White (60%). Compared to those classified as robust, those categorized as frail had 2.5 (95% CI: 1.86-3.23), 3.1 (95% CI: 2.28-4.12), and 0.3 (95% CI: 0.23-0.42) times the adjusted odds of trauma team activation, inpatient admission, and ED discharge, respectively. Also, those classified as frail had significantly longer lengths of hospital stay as well as 3.7 (1.07-12.62), 0.4 (0.28-0.47), and 2.2 (95% CI: 1.71-2.91) times the odds of in-hospital death, home discharge, and discharge to rehabilitation, respectively. CONCLUSION/CONCLUSIONS:Pre-injury frailty is a predictor of clinical care trajectories for older adults with trauma injuries.

INTRODUCTION/UNASSIGNED:To assess the association of race and ethnicity with self-reported personal protective equipment shortages during the COVID-19 pandemic among healthcare workers in New York. METHODS/UNASSIGNED:The COVID-19 Healthcare Personnel Study of New York was a prospective cohort study of HCWs with baseline data collected in April 2020 and follow-up data collected in February 2021. Multivariable logistic regression modeling was used to estimate the adjusted OR and 95% CIs of personal protective equipment shortages associated with race and ethnic minority status. RESULTS/UNASSIGNED:=0.005). With adjustment for demographic and clinical characteristics, racial and ethnic minority status was associated with 44% and 49% increased odds of experiencing PPE shortages at baseline (adjusted OR=1.44; 95% CI=1.10, 1.88) and follow up (adjusted OR=1.49; 95% CI=1.01, 2.21), respectively. CONCLUSIONS/UNASSIGNED:Healthcare workers of racial and ethnic minority status in New York experienced more pervasive personal protective equipment shortages than their non-Hispanic White counterparts during the COVID-19 pandemic.

PURPOSE/OBJECTIVE:The premature infant brain may be particularly vulnerable to anesthesia effects, but there is conflicting evidence on the association between anesthesia exposure and developmental outcomes. Twin studies can control for confounding factors. A twin cohort of premature twins provides internal control of difficulty to measure confounders and delivers added power to a study examining the effects of anesthesia on neurodevelopmental outcomes. METHODS:We conducted a retrospective cohort study of sets of premature twins and multiples born at an academic medical center, in which 1 member of the set was exposed to general anesthesia. The primary outcome was the composite scores using Bayley Scale of Infant and Toddler Development III performed at age 6 months to 18 months. Unpaired and paired analyses were performed with linear regression models, Wilcoxon signed rank test, and Mann-Whitney U test. RESULTS:We identified 81 children born at less than 32 weeks gestation within 39 sets of twins and 1 set of triplets for a total of 18 paired observations. All of the exposed infants had a single exposure to general anesthesia. There was no significant association between anesthesia exposure and a diagnosis of developmental delay (OR = 0.8; 95% confidence interval, 0.2-3.2; p = 0.99). Regression models demonstrated no association between anesthesia exposure and cognitive (96.67 vs 97.50; p = 0.74), language (98.33 vs 98.61; p = 0.94), or motor (96.25 vs 96.44; p = 0.91) composite Bayley scores. There was no association between duration of anesthesia and the 3 composite Bayley scores ( p = 0.33; p = 0.40; p = 0.74). CONCLUSION/CONCLUSIONS:Using a premature twin cohort with discordant exposure to anesthesia, our data did not demonstrate any association between anesthesia exposure and developmental delay in this vulnerable population of premature infants.

BACKGROUND/UNASSIGNED:Annually since 2008; over 38% of fatally injured motorcycle riders and 20% of pedalcyclists involved in traffic crashes were under the influence of alcohol, yet public health surveillance of alcohol involvement in these injuries is underdeveloped. This study determined alcohol involvement among fatally and non-fatally injured pedalcycle and motorcycle riders and compared findings across three national public-use datasets. METHODS/UNASSIGNED:Using the 2019 National Emergency Medical Services Information System (NEMSIS), the Fatality Analysis Reporting System (FARS), and National Electronic Injury Surveillance System (NEISS) datasets, we identified alcohol involvement in fatal and non-fatal injuries to pedalcycle and motorcycle riders (≥21 years). Alcohol involvement was positive based on the clinician's evaluation of alcohol at the scene (NEMSIS) or within the ED record (NEISS); or when Blood Alcohol Content (BAC) values were ≥.01 (FARS). Pedalcycle and motorcycle injuries were identified across datasets using: 1) ICD10 codes for pedalcycle (V10-V19) or motorcycle (V20-V29) within the cause of injury and EMS respondent's impression of the encounter variables (NEMSIS); 2) product codes for bicycles or moped/power-assisted cycle/minibike/two-wheeled, powered, off-road vehicles (NEISS); and 3) American National Standard Institute's classifications for pedalcycle and motorcycle in the person and vehicle type variables (FARS). The descriptive epidemiology was compared across datasets. RESULTS/UNASSIGNED:There were 26,295 pedalcyclist and 50,122 motorcycle rider injuries resulting in an EMS response within NEMSIS data; 10.2% and 8.5% of these injuries respectively involved alcohol. These estimates were greater than the 7.3% of pedalcyclist and 6.1% of moped/power-assisted cycle/minibike/two-wheeled, powered, off-road vehicle injuries involving alcohol among patients who presented to an ED within the NEISS dataset. Based on FARS data, alcohol was involved in 27.0% of pedalcyclist and 42.0% of motorcyclist fatal injuries. Regardless of the data source, pedalcyclist and motorcycle fatal and non-fatal injuries were more likely to involve alcohol among middle-aged adults compared to older and early aged adults, and for men compared to women, with proportions that were generally 3-8% higher for men. CONCLUSIONS/UNASSIGNED:Measures for pedalcycle and motorcycle injuries and alcohol involvement vary substantially across national public-use datasets. Standardized, valid, and feasible methods are needed to accurately inform injury prevention efforts.

INTRODUCTION/BACKGROUND:This study aimed to assess emergency nurses' perceived barriers toward engaging patients in serious illness conversations. METHODS:Using a mixed-method (quant + QUAL) convergent design, we pooled data on the emergency nurses who underwent the End-of-Life Nursing Education Consortium training across 33 emergency departments. Data were extracted from the End-of-Life Nursing Education Consortium post-training questionnaire, comprising a 5-item survey and 1 open-ended question. Our quantitative analysis employed a cross-sectional design to assess the proportion of emergency nurses who report that they will encounter barriers in engaging seriously ill patients in serious illness conversations in the emergency department. Our qualitative analysis used conceptual content analysis to generate themes and meaning units of the perceived barriers and possible solutions toward having serious illness conversations in the emergency department. RESULTS:A total of 2176 emergency nurses responded to the survey. Results from the quantitative analysis showed that 1473 (67.7%) emergency nurses reported that they will encounter barriers while engaging in serious illness conversations. Three thematic barriers-human factors, time constraints, and challenges in the emergency department work environment-emerged from the content analysis. Some of the subthemes included the perceived difficulty of serious illness conversations, delay in daily throughput, and lack of privacy in the emergency department. The potential solutions extracted included the need for continued training, the provision of dedicated emergency nurses to handle serious illness conversations, and the creation of dedicated spaces for serious illness conversations. DISCUSSION/CONCLUSIONS:Emergency nurses may encounter barriers while engaging in serious illness conversations. Institutional-level policies may be required in creating a palliative care-friendly emergency department work environment.
