ABSTRACT
BACKGROUND: The utilization of stereotactic body radiation therapy (SBRT) is increasing for primary and secondary lung neoplasms. Despite encouraging results, SBRT is associated with an increased risk of osteoradionecrosis-induced rib fracture. We aimed to (1) evaluate potential clinical, demographic, and procedure-related risk factors for rib fractures and (2) describe the radiographic features of post-SBRT rib fractures. METHODS: We retrospectively identified 106 patients who received SBRT between 2015 and 2018 for a primary or metastatic lung tumor with at least 12 months of follow up. Exclusion criteria were incomplete records, previous ipsilateral thoracic radiation, or relevant prior trauma. Computed tomography (CT) images were reviewed to identify and characterize rib fractures. Multivariate logistic regression modeling was employed to determine clinical, demographic, and procedural risk factors (e.g., age, sex, race, medical comorbidities, dosage, and tumor location). RESULTS: A total of 106 patients with 111 treated tumors met the inclusion criteria, 35 (32%) of whom developed at least one fractured rib (60 total fractured ribs). The highest number of fractured ribs per patient was five. Multivariate regression identified posterolateral tumor location as the only independent risk factor for rib fracture. On CT, fractures showed discontinuity between healing edges in 77% of affected patients. CONCLUSIONS: Nearly one third of patients receiving SBRT for lung tumors experienced rib fractures, 34% of whom experienced pain. Many patients developed multiple fractures. Post-SBRT fractures demonstrated a unique discontinuity between the healing edges of the rib, a distinct feature of post-SBRT rib fractures. The only independent predictor of rib fracture was tumor location along the posterolateral chest wall. Given its increasing frequency of use, describing the risk profile of SBRT is vital to ensure patient safety and adequately inform patient expectations.

BACKGROUND: Although lung cancer screening (LCS) for high-risk individuals reduces lung cancer mortality in clinical trial settings, many questions remain about how to implement high-quality LCS in real-world programs. With the increasing use of telemedicine in healthcare, studies examining this approach in the context of LCS are urgently needed. We aimed to identify sociodemographic and other factors associated with screening completion among individuals undergoing telemedicine Shared Decision Making (SDM) for LCS. METHODS: This retrospective study examined patients who completed Shared Decision Making (SDM) via telemedicine between May 4, 2020 - March 18, 2021 in a centralized LCS program. Individuals were categorized into Complete Screening vs. Incomplete Screening subgroups based on the status of subsequent LDCT completion. A multi-level, multivariate model was constructed to identify factors associated with incomplete screening. RESULTS: Among individuals undergoing telemedicine SDM during the study period, 20.6% did not complete a LDCT scan. Bivariate analysis demonstrated that Black/African-American race, Medicaid insurance status, and new patient type were associated with greater odds of incomplete screening. On multi-level, multivariate analysis, individuals who were new patients undergoing baseline LDCT or resided in a census tract with a high level of socioeconomic deprivation had significantly higher odds of incomplete screening. Individuals with a greater level of education experienced lower odds of incomplete screening. CONCLUSIONS: Among high-risk individuals undergoing telemedicine SDM for LCS, predictors of incomplete screening included low education, high neighborhood-level deprivation, and new patient type. Future research should focus on testing implementation strategies to improve LDCT completion rates while leveraging telemedicine for high-quality LCS.

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: Racial disparities are well-documented in preventive cancer care, but they have not been fully explored in the context of lung cancer screening. We sought to explore racial differences in lung cancer screening outcomes within a lung cancer screening program (LCSP) at our urban academic medical center including differences in baseline low-dose computed tomography (LDCT) results, time to follow-up, adherence, as well as return to annual screening after additional imaging, loss to follow-up, and cancer diagnoses in patients with positive baseline scans. METHODS: A historical cohort study of patients referred to our LCSP was conducted to extract demographic and clinical characteristics, smoking history, and lung cancer screening outcomes. RESULTS: After referral to the LCSP, blacks had significantly lower odds of receiving LDCT compared to whites, even while controlling for individual lung cancer risk factors and neighborhood-level factors. Blacks also demonstrated a trend toward delayed follow-up, decreased adherence, and loss to follow-up across all Lung-RADS categories. CONCLUSIONS: Overall, lung cancer screening annual adherence rates were low, regardless of race, highlighting the need for increased patient education and outreach. Furthermore, the disparities in race we identified encourage further research with the purpose of creating culturally competent and inclusive LCSPs.

Women comprise more than one third of the active physician workforce, an estimated 46% of all physicians-in-training, and more than half of all medical students in the United States. Although progress has been made toward gender diversity in the physician workforce, disparities in compensation exist and inequities have contributed to a disproportionately low number of female physicians achieving academic advancement and serving in leadership positions. Women in medicine face other challenges, including a lack of mentors, discrimination, gender bias, cultural environment of the workplace, imposter syndrome, and the need for better work-life integration. In this position paper, the American College of Physicians summarizes the unique challenges female physicians face over the course of their careers and provides recommendations to improve gender equity and ensure that the full potential of female physicians is realized.

Substance use disorders involving illicit and prescription drugs are a serious public health issue. In the United States, millions of individuals need treatment for substance use disorders but few receive it. The rising number of drug overdose deaths and the changing legal status of marijuana pose new challenges. In this position paper, the American College of Physicians maintains that substance use disorder is a treatable chronic medical condition and offers recommendations on expanding treatment options, the legal status of marijuana, addressing the opioid epidemic, insurance coverage of substance use disorders treatment, education and workforce, and public health interventions.

The purpose of the fourth year of medical school remains controversial. Competing demands during this transitional phase cause confusion for students and educators. In 2014, the Association of American Medical Colleges (AAMC) released 13 Core Entrustable Professional Activities for Entering Residency (CEPAERs). A committee comprising members of the Clerkship Directors in Internal Medicine and the Association of Program Directors in Internal Medicine applied these principles to preparing students for internal medicine residencies. The authors propose a curricular framework based on five CEPAERs that were felt to be most relevant to residency preparation, informed by prior stakeholder surveys. The critical areas outlined include entering orders, forming and answering clinical questions, conducting patient care handovers, collaborating interprofessionally, and recognizing patients requiring urgent care and initiating that care. For each CEPAER, the authors offer suggestions about instruction and assessment of competency. The fourth year of medical school can be rewarding for students, while adequately preparing them to begin residency, by addressing important elements defined in the core entrustable activities. Thus prepared, new residents can function safely and competently in supervised postgraduate settings.

BACKGROUND: Lung cancer screening uptake for individuals at high risk is generally low across the United States, and reporting of lung cancer screening practices and outcomes is often limited to single hospitals or institutions. We describe a citywide, multicenter analysis of individuals receiving lung cancer screening integrated with geospatial analyses of neighborhood-level lung cancer risk factors. METHODS: The Philadelphia Lung Cancer Learning Community consists of lung cancer screening clinicians and researchers at the 3 largest health systems in the city. This multidisciplinary, multi-institutional team identified a Philadelphia Lung Cancer Learning Community study cohort that included 11â222 Philadelphia residents who underwent low-dose computed tomography for lung cancer screening from 2014 to 2021 at a Philadelphia Lung Cancer Learning Community health-care system. Individual-level demographic and clinical data were obtained, and lung cancer screening participants were geocoded to their Philadelphia census tract of residence. Neighborhood characteristics were integrated with lung cancer screening counts to generate bivariate choropleth maps. RESULTS: The combined sample included 37.8% Black adults, 52.4% women, and 56.3% adults who currently smoke. Of 376 residential census tracts in Philadelphia, 358 (95.2%) included 5 or more individuals undergoing lung cancer screening, and the highest counts were geographically clustered around each health system's screening sites. A relatively low percentage of screened adults resided in census tracts with high tobacco retailer density or high smoking prevalence. CONCLUSIONS: The sociodemographic characteristics of lung cancer screening participants in Philadelphia varied by health system and neighborhood. These results suggest that a multicenter approach to lung cancer screening can identify vulnerable areas for future tailored approaches to improving lung cancer screening uptake. Future directions should use these findings to develop and test collaborative strategies to increase lung cancer screening at the community and regional levels.

INTRODUCTION: Pulmonary carcinoid tumor (PCT) is a rare neuroendocrine lung neoplasm comprising approximately 2% of lung cancer diagnoses. It is classified as either localized low-grade (typical) or intermediate-grade (atypical) subtypes. PCT is known clinically to be a slow-growing cancer, however few studies have established its true growth rate when followed over time by computed tomography (CT). Therefore, we sought to determine the volume doubling time for PCTs as visualized on CT imaging. MATERIALS AND METHODS: We conducted a retrospective analysis of all PCTs treated at our institution between 2006 and 2020. Nodule dimensions were measured using a Picture Archiving and Communication System or retrieved from radiology reports. Volume doubling time was calculated using the Schwartz formula for PCTs followed by successive CT scans during radiographic surveillance. Consistent with Fleischner Society guidelines, tumors were considered to have demonstrated definitive growth by CT only when the interval change in tumor diameter was greater than or equal to 2 mm. RESULTS: The median volume doubling time of 13 typical PCTs was 977 days, or 2.7 years. Five atypical PCTs were followed longitudinally, with a median doubling time of 327 days, or 0.9 years. CONCLUSIONS: Typical pulmonary carcinoid features a remarkably slow growth rate as compared to more common lung cancers. Our analysis of atypical pulmonary carcinoid included too few cases to offer definitive conclusions. It is conceivable that clinicians following current nodule surveillance guidelines may mistake incidentally detected typical carcinoids for benign non-growing lesions when followed for less than 2 years in low-risk patients.

BACKGROUND: One challenge in high-quality lung cancer screening (LCS) is maintaining adherence with annual and short-interval follow-up screens among high-risk individuals who have undergone baseline low-dose CT (LDCT). This study aimed to characterize attitudes and beliefs toward lung cancer and LCS and to identify factors associated with LCS adherence. METHODS: We administered a questionnaire to 269 LCS participants to assess attitudes and beliefs toward lung cancer and LCS. Clinical data including sociodemographics and screening adherence were obtained from the LCS Program Registry. RESULTS: African-American individuals had significantly greater lung cancer worries compared with Whites (6.10 vs. 4.66, P < .001). In making the decision to undergo LCS, African-American participants described screening convenience and cost as very important factors significantly more frequently than Whites (60% vs. 26.8%, P< .001 and 58.4% vs. 37.8%, P = .001; respectively). African-American individuals with greater than high school education had significantly higher odds of LCS adherence (aOR 2.55; 95% CI, 1.14-5.60) than Whites with less than high school education. Participants who described screening convenience and cost as "very important" had significantly lower odds of completing screening follow-up after adjusting for demographic and other factors (aOR 0.56; 95% CI, 0.33-0.97 and aOR 0.54; 95% CI, 0.33-0.91, respectively). CONCLUSION: Racial differences in beliefs about lung cancer and LCS exist among African-American and White individuals enrolled in an LCS program. Cost, convenience, and low educational attainment may be barriers to LCS adherence, specifically among African-American individuals. IMPACT: More research is needed on how barriers can be overcome to improve LCS adherence.

Poverty is linked to negative health consequences and harmful health behaviors such as smoking. Despite this established correlation, few comparative studies have investigated the relationship between local poverty rates and smoking in urban settings through a Social Ecological Model framework. The authors sought to examine the linkage between local poverty rates in Philadelphia, Pennsylvania and adult smoking rates by scrutinizing existing patterns and potential mediating factors via publicly accessible data in established planning districts. The authors determined several individual, interpersonal, organizational, community, and environmental factors, varying across these districts, that impact smoking in Philadelphia. Poverty rates influence the resources, demographic makeup, and number of tobacco retailers a district has, which have downstream effects. The authors recommend that further investment is allocated to planning districts in order to mitigate the risk of smoking.

Audience: Emergency medicine residents (interns, junior residents), medical students, and mid-level providers (physician assistants, nurse practitioners). Introduction: Pneumothorax refers to the presence of gas within the pleural space and is a relatively common clinical entity in the emergency department.1 Traumatic pneumothorax results from blunt or penetrating trauma to the thorax. Iatrogenic pneumothorax is a risk inherent to a number of invasive procedures and represents a significant cause of preventable morbidity.2 Specifically, central venous catheterization (43.8%), thoracentesis (20.1%), and barotrauma due to mechanical ventilation (9.1%) are the most frequent causes.3A feared complication of pneumothorax is the development of tension pneumothorax, which involves the compression of mediastinal structures by increased pressures within the pleural space, leading to hemodynamic compromise.4 As tension pneumothorax is an emergent, life-threatening condition, the management of pneumothorax and the insertion of chest tubes are skills required of physicians involved in the care of injured patients, including general surgeons, intensivists, and emergency medicine physicians.5 The process of correcting pneumothorax is not without complication. Complications following chest tube insertion in trauma patients occur in 19% of cases,6 and are commonly a result of chest tubes placed by resident physicians.7The authors believe that a web-based learning module addressing topics related to pneumothorax (pathophysiology, clinical manifestations, diagnosis, and management) would be beneficial to healthcare providers who are likely to encounter pneumothorax in clinical practice. Specifically, the web-based nature of the module would lend itself to convenient viewing and would allow for utilization as a just-in-time training modality. Presenting these topics in an animated format may also be a useful way of capturing the complex and three-dimensional nature of respiratory physiology. Additionally, the web-based format may be particularly appealing to digital native natives, who occupy an increasing percentage of resident physician positions.8 It should be noted that a number of studies have examined the use of computerized modules in medical education, and found them to be at least as useful as traditional instructional methods, and are typically associated with high rates of satisfaction among learners.9-13. Educational Objectives: By the end of this module, participants should be able to:Review the normal physiology of the pleural spaceDiscuss the pathophysiology of pneumothoraxDescribe the clinical presentation of pneumothoraxIdentify pneumothorax on a chest radiographReview treatment options for pneumothorax. Educational Methods: This is a video podcast, which conveys information through animated content. It is available to learners on demand and just-in-time for practice. It may be used as a stand-alone educational tool, as a primer to other instructional methods (eg, simulation), or a just-in-time training tool. Research Methods: A small-scale study was conducted to evaluate the efficacy of this module as an educational tool. The learner group consisted of a convenience sample of 11 second-year medical students at the end of their pre-clinical training. All learners were administered the attached assessment form as a pre-test, shown the video, then asked to re-take the assessment as a post-test to assess improvement. Assessments were graded on a 10-point scale according to the attached answer key. Learners were also given the opportunity to rate the quality of the module as an educational tool, as well as to provide subjective feedback. Results: The average pre-test score across all learners was 34%. The average post-test score across all learners was 82%, representing an improvement of 48%. Learners were asked to rate their agreement with the statements, "This module effectively taught concepts related to pulmonary physiology and pneumothorax," and, "The animated format of this module was useful for illustrating concepts related to pulmonary physiology and pneumothorax." All learners responded with "agree" or "strongly agree" for each statement. When given the opportunity to provide subjective feedback regarding the module, learners responded with "This module is a great review! It is well organized, has effective animations, and information is clear," and "Helpful review that explained the concepts in an accessible way!" Discussion: Results from the pre-test and post-test suggest that this module was effective in teaching concepts related to pulmonary physiology and pneumothorax. All learners reported satisfaction with the animated format in particular. These results suggest that this module would be effective as a standalone educational tool or as a primer to other instructional methods. Topics: Pneumothorax, thoracostomy, needle decompression, flipped classroom, asynchronous learning, emergency medicine.
ABSTRACT
BACKGROUND: Bronchiolitis obliterans organizing pneumonia (BOOP) is a distinct pattern of reaction of the lung to injury. It may be idiopathic or secondary to a variety of injuries. The term cryptogenic organizing pneumonia (COP) is used for patients with idiopathic BOOP. In this study we describe clinical and radiologic features of patients with BOOP. METHODS: The medical records of 33 patients with diagnosis of BOOP on surgical lung biopsy over a 10-year time period were reviewed retrospectively. We obtained data on clinical and radiologic manifestations, etiology, and outcome of these patients. RESULTS: Dyspnea was the most common symptom, followed by dry cough and fever. Crackles was the most common physical finding. Mean age at diagnosis of BOOP was 59 years, and 42% were females. The main radiologic manifestation was bilateral patchy consolidation. Most patients had favorable prognosis; however, 17% did not respond to treatment. Female sex was more common in COP than in secondary BOOP (P = .004). Patients with COP had longer symptom duration before the diagnosis than secondary BOOP (P = .01). Patients with secondary BOOP reported fever more frequently, compared to COP (P = .005). Pleural effusion was present in 60% of patients with secondary BOOP, whereas none of the patients with COP had effusion (P = .004). CONCLUSIONS: COP and secondary BOOP have diverse clinical and radiologic manifestations. Patients with secondary BOOP are more symptomatic. Both COP and secondary BOOP patients have good prognosis, and most respond to treatment with corticosteroids or by discontinuing the injurious drug.
