Harnessing Opportunity: Pilot Intervention to Improve Lung Cancer Screening for Women Undergoing Breast Screening Mammography.

Introduction: The screening mammogram could be a "teachable moment" to improve lung cancer screening (LCS) uptake. The aim of our project was to combine patient self-referral with eligibility identification by providers as a two-pronged approach to increase rates of LCS among eligible women. Methods: LCS education materials were created to stimulate patient education and encourage self-referral. Chart review of patients scheduled for screening mammography was performed to identify patients who met LCS criteria. The primary outcome was rate of acceptance of targeted interventions as measured by qualitative survey material and rate of LCS uptake. Results: Between August 2022 and August 2023, 116 patients were identified by providers for potential eligibility for LCS and 34 patients (29.3%) deemed eligible based on the U.S. Preventative Services Task Force 2021 guidelines. There were 19 patients (56%) who completed LCS with three patients (16%) with screen-detected nodules that led to further workup. Post-implementation qualitative survey results reveal that 100% of the participants rated their shared decision-making visit experience as "very helpful" and 67% responded "very likely" to seek simultaneous breast and LCS in the future. Informational materials were rated as 80% favorable among all respondents; however, the rate of self-referral alone was 0%. The combined rates of eligible patients lost to follow-up or refusal was 24%. Conclusion: The self-referral aspect of the intervention revealed that patients are unlikely to self-refer for LCS. Nevertheless, patients undergoing screening mammograms individually identified for LCS were very responsive to learning more about dual screening.

Partial Tendon Injury at the Tendon-to-Bone Enthesis Activates Skeletal Stem Cells.

The tendon enthesis plays a critical role in facilitating movement and reducing stress within joints. Partial enthesis injuries heal in a mechanically inferior manner and never achieve healthy tissue function. The cells responsible for tendon-to-bone healing remain incompletely characterized and their origin is unknown. Here, we evaluated the putative role of mouse skeletal stem cells (mSSCs) in the enthesis after partial-injury. We found that mSSCs were present at elevated levels within the enthesis following injury and that these cells downregulated TGFß signaling pathway elements at both the RNA and protein levels. Exogenous application of TGFß post-injury led to a reduced mSSC response and impaired healing, whereas treatment with a TGFß inhibitor (SB43154) resulted in a more robust mSSC response. Collectively, these data suggest that mSSCs may augment tendon-to-bone healing by dampening the effects of TGFß signaling within the mSSC niche.

A national analysis of open versus minimally invasive thymectomy for stage I-III thymic carcinoma.

OBJECTIVES: The oncological efficacy of minimally invasive thymectomy for thymic carcinoma is not well characterized. We compared overall survival and short-term outcomes between open and minimally invasive surgical (video-assisted thoracoscopic and robotic) approaches using the National Cancer Database. METHODS: Perioperative outcomes and overall survival of patients who underwent open versus minimally invasive thymectomy for Masaoka stage I-III thymic carcinoma from 2010 to 2015 in the National Cancer Database were evaluated using propensity score-matched analysis and multivariable Cox proportional hazards modelling. Outcomes by surgical approach were assessed using an intent-to-treat analysis. RESULTS: Of the 216 thymectomies that were evaluated, 43 (20%) were performed with minimally invasive techniques (22 video-assisted thoracoscopic and 21 robotic). The minimally invasive approach was associated with a shorter median length of stay when compared to the open approach (3 vs 5 days, P < 0.001). In the propensity score-matched analysis of 30 open and 30 minimally invasive thymectomies, the minimally invasive group did not differ significantly in median length of stay (3 vs 4.5 days, P = 0.27), 30-day readmission (P = 0.13), 30-day mortality (P = 0.60), 90-day mortality (P = 0.60), margin positivity (P = 0.39) and 5-year survival (78.6% vs 54.6%, P = 0.15) when compared to the open group. CONCLUSIONS: In this national analysis, minimally invasive thymectomy for stage I-III thymic carcinoma was found to have no significant differences in short-term outcomes and overall survival when compared to open thymectomy.

The role of gender in non-small cell lung cancer: a narrative review.

The role of gender in the development, treatment and prognosis of thoracic malignancies has been underappreciated and understudied. While most research has been grounded in tobacco-related malignancies, the incidence of non-smoking related lung cancer is on the rise and disproportionately affecting women. Recent research studies have unveiled critical differences between men and women with regard to risk factors, timeliness of diagnosis, incongruent screening practices, molecular and genetic mechanisms, as well as response to treatment and survival. These studies also highlight the increasingly recognized need for targeted therapies that account for variations in the response and complications as a function of gender. Similarly, screening recommendations continue to evolve as the role of gender is starting to be ellucidated. As women have been underrepresented in clinical trials until recently, the data regarding optimal care and outcomes is still lagging behind. Understanding the underlying similarities and differences between men and women is paramount to providing adequate care and prognostication to patients of either gender. This review provides an overview of the critical role that gender plays in the care of patients with non-small cell lung cancer and other thoracic malignancies, with an emphasis on the need for increased awareness and further research to continue elucidating these disparities.

Impact of the Surgical Approach to Thymectomy Upon Complete Stable Remission Rates in Myasthenia Gravis: A Meta-analysis.

OBJECTIVES: To determine whether the available operative techniques for thymectomy in myasthenia gravis (MG) confer variable chances for achieving complete stable remission (CSR), we performed a meta-analysis of comparative studies of surgical approaches to thymectomy. METHODS: Meta-analysis was done of all studies providing comparative data on thymectomy approaches, with CSR reported and minimum 3-year mean follow-up. RESULTS: Twelve cohort studies and 1 randomized clinical trial, containing 1,598 patients, met entry criteria. At 3 years, CSR from MG was similar after video-assisted thoracoscopic (VATS) extended vs both basic (relative risk [RR] 1.00, p = 1.00, 95% confidence interval [CI] 0.39-2.58) and extended (RR 0.96, p = 0.74, 95% CI 0.72-1.27) transsternal approaches. CSR at 3 years was also similar after extended transsternal vs combined transcervical-subxiphoid (RR 1.08, p = 0.62, 95% CI 0.8-1.44) approaches. VATS extended approaches remained statistically equivalent to extended transsternal approaches through 9 years of follow-up (RR 1.51, p = 0.05, 95% CI 0.99-2.30). The only significant difference in CSR rate between a traditional open and a minimally invasive approach was seen at 10 years when the now-abandoned basic (non-sternum-lifting) transcervical approach was compared to the extended transsternal approach (RR 0.4, p = 0.01, 95% CI 0.2-0.8). CONCLUSIONS: A significant difference in the rate of CSR among various surgical approaches for thymectomy in MG was identified only at long-term follow-up and only between what might be considered the most aggressive approach (extended transsternal thymectomy) and the least aggressive approach (basic transcervical thymectomy). Extended minimally invasive approaches appear to have CSR rates equivalent to those of extended transsternal approaches and are therefore appropriate in the hands of experienced surgeons.

Impact of policy-based and institutional interventions on postoperative opioid prescribing practices.

BACKGROUND: We assessed the impact of policy-based and institutional interventions to limit postoperative opioid prescribing. METHODS: Retrospective cohort study of patients who underwent laparoscopic/open appendectomies, laparoscopic/open cholecystectomies, and laparoscopic/open inguinal hernia repair during a 6-month interval in 2018 (control), 2019 (post-policy intervention), and 2020 (post-institutional intervention) to assess changes in postoperative opioid prescribing patterns. A survey was collected for the 2020 cohort. RESULTS: Comparing the 762 patients identified in 2018, 2019, and 2020 cohorts there was a significant decrease in mean opioid tabs prescribed (23.5 ± 8.9 vs. 16.2 ± 7.0 vs. 12.8 ± 4.9, p < 0.01) and mean OME dosage (148.0 ± 68.0 vs. 108.6 ± 51.8 vs. 95.4 ± 38.0, p < 0.01), without a difference in refill requests. Patient survey (response rate 63%) indicated 91.4% of patients reported sufficient pain control. CONCLUSION: Formalized opioid-prescribing guidelines and statewide regulations can significantly decrease postoperative opioid prescribing with good patient satisfaction. Surgeon education may facilitate efforts to minimize narcotic over-prescription without compromising pain management.

A National Analysis of Minimally Invasive Vs Open Segmentectomy for Stage IA Non-Small-Cell Lung Cancer.

The objective of this study was to compare long-term outcomes of open vs minimally invasive (MIS) segmentectomy for early stage non-small-cell lung cancer (NSCLC), which has not been previouslyevaluated using national studies. Outcomes of open vs MIS segmentectomy for clinical T1, N0, M0 NSCLC in the National Cancer Data Base (2010-2015) were evaluated using propensity score matching. Of the 39,351 patients who underwent surgery for stage IA NSCLC from 2010 to 2015, 770 underwent segmentectomy by thoracotomy and 1056 by MIS approach (876 thoracoscopic [VATS], 180 robotic). The MIS to open conversion rate was 6.7% (n = 71). After propensity score matching, all baseline characteristics were well-balanced between the open (n = 683) and MIS (n = 683) groups. When compared to the open group, the MIS group had shorter median length of stay (4 vs 5 days, P< 0.001) and lower 30-day mortality (0.6% vs 1.9%, P = 0.037). There were no significant differences between MIS and open groups with regard to 30-day readmission (5.0% vs 3.7%, P = 0.43), or upstaging from cN0 to pN1/N2/N3 (3.1% vs 3.6%, P = 0.89). The MIS approach was associated with similar long-term overall survival as the open approach (5-year survival: 62.3% vs 63.5%, P = 0.89; multivariable-adjusted hazard ratio: 0.99, 95% Confidence Intervial (CI): 0.82-1.21, P = 0.96). In this national analysis of open vs MIS segmentectomy for clinical stage IA NSCLC, MIS was associated with shorter length of stay and lower perioperative mortality, and similar nodal upstaging and 5-year survival when compared to segmentectomy via thoracotomy. MIS segmentectomy does not appear to compromise oncologic outcomes for clinical stage IA NSCLC.

Understanding Health Care Utilization and Mortality After Emergency General Surgery in Patients With Underlying Liver Disease.

BACKGROUND: Mortality and complications are not well defined nationally for emergency general surgery (EGS) patients presenting with underlying all-cause liver disease (LD). STUDY DESIGN: We analyzed the 2012-2014 National Inpatient Sample for adults (aged ≥ 18 years) with a primary EGS diagnosis. Underlying LD included International Classification of Diseases, Ninth Revision, Clinical Modification codes for alcoholic and viral hepatitis, malignancy, congenital etiologies, and cirrhosis. The primary outcome was mortality; secondary outcomes included complications, operative intervention, and costs. RESULTS: Of the 6.8 million EGS patients, 358 766 (5.3%) had underlying LD. 59.1% had cirrhosis, 6.7% had portal hypertension, and 13.7% had ascites. Compared with other EGS patients, EGS-LD patients had higher mean costs ($12 847 vs $10 234, P < .001). EGS-LD patients were less likely to have surgery (26.1% vs 37.0%, P < .001) but for those who did, mortality was higher (4.8% vs 1.8%, P < .001). Risk factors for mortality included ascites (adjusted odds ratio [aOR] = 2.68, P < .001), dialysis (aOR = 3.44, P < .001), sepsis (aOR = 8.97, P < .001), and respiratory failure requiring intubation (aOR = 10.40, P < .001). Odds of death increased in both surgical (aOR = 4.93, P < .001) and non-surgical EGS-LD patients (aOR = 2.56, P < .001). CONCLUSIONS: Underlying all-cause LD among EGS patients is associated with increased in-hospital mortality, even in the absence of surgical intervention.
