Relationship of Surgical Approach With Financial Toxicity in Patients With Resected Lung Cancer.

INTRODUCTION: Minimally invasive surgery (MIS) reduces lengths of stay, complications, and potentially perioperative hospital costs. However, the impact of MIS on financial toxicity (FT), defined as the costs resulting from oncologic care and their negative effects on quality of life, in patients with lung cancer is unknown. Our objective was to investigate the association between surgical approach and FT in this population. METHODS: A single-institution study was performed evaluating resected lung cancer patients (2016-2021). FT was assessed using the Comprehensive Score for Financial Toxicity (COST) questionnaire. The relationship between surgical approach (MIS vs. thoracotomy) and FT was evaluated using propensity score-matched (PSM) regression analysis. A sensitivity analysis involving the entire cohort was also performed using an inverse probability-weighted generalized linear model. RESULTS: As reported previously, of 1477 patients surveyed, 463 responded (31.3%) with FT reported in 196 patients (42.3%). Resection was performed by thoracotomy in 53.3% (n = 247), and by MIS in the remainder (n = 216, 46.7%; video-assisted thoracoscopic surgery [VATS] = 115; robotic-assisted = 101). There was no difference in FT in patients who underwent VATS and robotic-assisted surgery (p = 0.515). In the PSM analysis, MIS was not associated with FT (odds ratio [OR]: 0.980, 95% confidence interval [CI]: 0.628-1.533, p = 0.929). Similar results were found on sensitivity analysis (OR: 1.488, CI: 0.931-2.378, p = 0.096). CONCLUSIONS: Compared to MIS, thoracotomy was not associated with FT in patients with resected lung cancer. Though there are several benefits from MIS, it does not appear to be a meaningful strategy to alleviate FT in this population.

5α-reductase inhibitors with or without alpha-blockers and risk of incident upper tract urothelial carcinoma in men with benign prostatic hyperplasia: Analysis of US insurance claims data.

BACKGROUND: Increasing data suggests that androgen receptor signaling may play an important role in the carcinogenesis of urothelial cancers. While the chemoprotective effect of 5-alpha reductase inhibitors (5-ARi) on bladder cancer risk in men with Benign Prostatic Hyperplasia (BPH) has been explored with conflicting results, the evidence regarding 5-ARi treatment, and the risk of incident Upper Tract Urothelial Carcinoma (UTUC) development is lacking. Therefore, our objective was to investigate the impact of the 5-ARi administration on the incidence of new UTUC cases using a large US database. METHODS: The MerativeTM Marketscan® database was used to identify men ≥ 50 years old with a diagnosis of BPH and an active 5-ARi prescription between 2007 and 2021 and were subsequently matched with paired controls. A multivariable Cox regression model was implemented to ascertain the association of 5-ARi and/or alpha-blocker (α-B) medications on the incidence of UTUC. Additional subgroup analyses were conducted based on exposure risk (with a 2-year threshold) to investigate the relationship between 5-ARi and UTUC over time. RESULTS: Overall, n=1,103,743 men BPH without prescriptions for BPH, n=31,142 men on 5-ARi, and n=160,049 using 5-ARi + α-B were identified. Over the follow-up period, a total of n=4,761 patients were diagnosed with UTUC. After matching, UTUC incidence ranged from 0.36% to 0.41% in men without active BPH therapy vs. 0.30% and 0.52% for the 5-ARi and 5-ARi + α-B groups, respectively. In multivariable analysis, the chemoprotective effect on UTUC risk was not observed for either 5-ARi monotherapy (adjusted hazard ratio [aHR]: 0.91, 95% CI: 0.58-1.44) or 5-ARi + α-B combination (aHR: 1.02, 95% CI: 0.87-1.19). This remained true for both short-term (≤ 2 years) and long-term (> 2 years) follow-up periods. CONCLUSIONS: The use of 5-ARi for BPH, whether used alone or in combination with α-B, is not associated with incident UTUC.

Assessing Artificial Intelligence-Generated Responses to Urology Patient In-Basket Messages.

INTRODUCTION: Electronic patient messaging utilization has increased in recent years and has been associated with physician burnout. ChatGPT is a language model that has shown the ability to generate near-human level text responses. This study evaluated the quality of ChatGPT responses to real-world urology patient messages. METHODS: One hundred electronic patient messages were collected from a practicing urologist's inbox and categorized based on the question content. Individual responses were generated by entering each message into ChatGPT. The questions and responses were independently evaluated by 5 urologists and graded on a 5-point Likert scale. Questions were graded based on difficulty, and responses were graded based on accuracy, completeness, harmfulness, helpfulness, and intelligibleness. Whether or not the response could be sent to a patient was also assessed. RESULTS: Overall, 47% of responses were deemed acceptable to send to patients. ChatGPT performed better on easy questions with 56% of responses to easy questions being acceptable to send as compared to 34% of difficult questions (P = .03). Responses to easy questions were more accurate, complete, helpful, and intelligible than responses to difficult questions. There was no difference in response quality based on question content. CONCLUSIONS: ChatGPT generated acceptable responses to nearly 50% of patient messages with better performance for easy questions compared to difficult questions. Use of ChatGPT to help respond to patient messages can help to decrease the time burden for the care team and improve wellness. Artificial intelligence performance will likely continue to improve with advances in generative artificial intelligence technology.

Sociodemographic Trends and Perinatal Outcomes in Fathers 50 Years and Older.

Importance: The age of fathers at childbirth is rising, with an increasing number of births attributed to older fathers. While the impact of advanced paternal age has been documented, sociodemographic data about fathers aged 50 years and older remain scarce. Objectives: To explore sociodemographic and temporal trends among the oldest US fathers (age ≥50 years) and their associations with perinatal outcomes. Design, Setting, and Participants: This retrospective cross-sectional study included data from all US births from 2011 to 2022 using the National Vital Statistics System. Data were analyzed from August 2023 and May 2024. Exposures: Reported paternal age at childbirth. Main Outcomes and Measures: Outcomes of interest were sociodemographic factors, temporal trends in older fatherhood, and perinatal outcomes, including preterm birth, low birth weight, gestational diabetes, gestational hypertension, assisted reproductive technology (ART), rates of maternal primiparity, and the infant sex ratio. Results: From 2011 to 2022, the US recorded 46 195 453 births, with an overall mean (SD) paternal age of 31.5 (6.8) years and 484 507 (1.1%) involving fathers aged 50 years or older, 47 785 (0.1%) aged 60 years or older, and 3777 (0.008%) aged 70 years or older. Births to fathers aged 50 years or older increased from 1.1% in 2011 to 1.3% in 2022 (P for trend < .001). Fathers aged 50 years or older were more diverse, with variations in educational achievement and race and ethnicity. Marital status and maternal racial and ethnic and educational backgrounds also varied by paternal age and race. Despite controlling for maternal age and other sociodemographic and perinatal factors, every 10-year increase in paternal age was consistently associated with greater use of ART (eg, age 50-59 years: adjusted odds ratio [aOR], 2.23; 95% CI, 2.19-2.27), higher likelihood of first maternal birth (eg, age 50-59 years: aOR, 1.16; 95% CI, 1.15-1.17), and increased risks of preterm birth (eg, age 50-59 years: aOR, 1.16; 95% CI, 1.15-1.18) and low birth weight (eg, age 50-59 years: aOR, 1.14; 95% CI, 1.13-1.15) compared with fathers aged 30 to 39 years. No significant changes in the infant sex ratio were observed, except among fathers aged 70 years or older (aOR, 0.92; 95% CI, 0.86-0.99) and 75 years or older (aOR, 0.84; 95% CI, 0.73-0.97), who showed a decreased likelihood of having male offspring. Conclusions and Relevance: In this cross-sectional study of all US births from 2011 to 2022, the percentage attributed to older fathers, while small, increased. Notable variations in paternal and maternal race and education were identified. Older fatherhood was associated with increased ART use, first-time maternal births, adverse perinatal outcomes, and altered sex ratio. Further research of this population is crucial for improving patient counseling and family planning.

Factors associated with dating app use for sexual "hookups" in the United States: insights from the National Survey of Family Growth.

BACKGROUND: The use of dating applications for matchmaking and sexual exploits ("hookups") has increased, and this modern phenomenon has supplanted traditional socialization and relationship formation. To date, sociodemographic data on the use of dating apps has been limited. AIM: In this study, we sought to identify predictors associated with the use of dating apps in the United States. METHODS: Using cross-sectional data from the 2017-2019 National Survey of Family Growth, we examined sociodemographic determinants influencing the use of dating apps to find partners for sexual intercourse. We constructed survey-weighted regression models to study these associations, with additional sensitivity analyses performed within specific subgroups. Furthermore, this study investigated the correlation of app use with sexual frequency. OUTCOME: Study outcomes were participant data regarding reported use of dating apps for sexual intercourse in the 2017-2019 National Survey of Family Growth. RESULTS: A total of 11,225 respondents were examined, representing a survey-weighted total of approximately 143,201, 286 Americans. Among them, 757 respondents (6.7%), equating to approximately 8, 818, 743 individuals, reported dating app use for sexual hookups. Regression analysis revealed that factors such as male sex, White race, previous sexual experience, substance/alcohol use, history of sexually transmitted infections, same-sex attraction, and bisexuality increased the likelihood of dating app usage. Conversely, reduced odds of dating app use were observed among Catholics, Protestants, married/widowed individuals, and older respondents. Stratified analyses across various demographics, including male and female individuals aged 20 to 40 years, heterosexual, and lesbian, gay, and bisexual respondents, generally supported these trends. Notably, dating app use did not correlate with increased sexual frequency (adjusted incidence rate ratio: 1.10; 95% CI: 0.96-1.26; P = .16). CLINICAL IMPLICATIONS: Dating app use is prevalent among male patients and White individuals and correlates with increased sexually transmitted infection risk, alcohol/illicit substance use, past sexual experience, and popularity within the lesbian, gay, and bisexual community, all important considerations for public health interventions. Dating app use, however, was not associated with increased sexual encounters. STRENGTHS AND LIMITATIONS: Strengths of our study were the utilization of a national survey of individuals of reproductive age in the United States and focus on a clearly defined outcome of dating app utilization for the purposes of sexual intercourse. Limitations include self-reported survey responses and insufficient detail on the types and duration of dating app platforms and their use. CONCLUSIONS: Many sociodemographic factors, including male sex, White race, history of STIs, substance and alcohol use, and same-sex and bisexual attraction, were linked with dating app use. However, there was no increase in sexual frequency associated with dating app utilization. Further research is essential for integrating these technologies into the relational and sexual dynamics of individuals.

Pulmonary Surgical Margins for Metastatic Osteosarcoma: Is Negative Margin Enough?

BACKGROUND: In advanced osteosarcoma, the lung is the most frequent site of distant metastasis, with metastasectomy often used for local disease control. The influence of pulmonary resection margin length on outcomes for osteosarcoma has not been well explored. This study sought to evaluate the impact of margin length relative to tumor size on local recurrence and survival in lung-limited metastatic osteosarcoma. METHODS: Patients with metastatic osteosarcoma who underwent lung resection between 2000 and 2020 were identified from a single institution. Clinicopathologic variables were collected. The margin length-to-tumor size ratio (MTR) was calculated per nodule and classified relative to an MTR of 0.5. The primary outcome was development of local recurrence per nodule. Multivariate logistic regression was used to investigate covariates. RESULTS: A total of 142 patients with 689 nodules met inclusion criteria, with mean age of 35.6 years (interquartile range [IQR], 20.9-46.6 years). Patients were predominantly male (n = 87; 61.3%) and White (n = 106; 72.5%). Most nodules (n = 644; 93.5%) were resected through thoracotomy. The mean tumor size was 0.8 cm (IQR, 0.5-1.70 cm), with an average margin length of 0.3 cm (IQR, 0.1-0.7 cm). Among all nodules, 299 (43.4%) had an MTR >0.5. Systemic therapy was received by 94 patients (66.2%) preoperatively and by 100 patients (70.4%) postoperatively. Importantly, the study found that an MTR >0.5 conferred a protective effect against disease recurrence (hazard ratio, 0.67; 95% CI, 0.52-0.87; P = .003). CONCLUSIONS: In resected pulmonary metastatic osteosarcoma, a margin length greater than one-half the size of the pulmonary nodule is associated with a lower incidence of local disease recurrence. This finding has implications for the subsequent need for additional therapy and disease-free status, thus meriting attentive intraoperative consideration.

Current global status of male reproductive health.

BACKGROUND: The widespread interest in male reproductive health (MRH), fueled by emerging evidence, such as the global decline in sperm counts, has intensified concerns about the status of MRH. Consequently, there is a pressing requirement for a strategic, systematic approach to identifying critical questions, collecting pertinent information, and utilizing these data to develop evidence-based strategies. The methods for addressing these questions and the pathways toward their answers will inevitably vary based on the variations in cultural, geopolitical, and health-related contexts. To address these issues, a conjoint ESHRE and Male Reproductive Health Initiative (MRHI) Campus workshop was convened. OBJECTIVE AND RATIONALE: The three objectives were: first, to assess the current state of MRH around the world; second, to identify some of the key gaps in knowledge; and, third, to examine how MRH stakeholders can collaboratively generate intelligent and effective paths forward. SEARCH METHODS: Each expert reviewed and summarized the current literature that was subsequently used to provide a comprehensive overview of challenges related to MRH. OUTCOMES: This narrative report is an overview of the data, opinions, and arguments presented during the workshop. A number of outcomes are presented and can be summarized by the following overarching themes: MRH is a serious global issue and there is a plethora of gaps in our understanding; there is a need for widespread international collaborative networks to undertake multidisciplinary research into fundamental issues, such as lifestyle/environmental exposure studies, and high-quality clinical trials; and there is an urgent requirement for effective strategies to educate young people and the general public to safeguard and improve MRH across diverse population demographics and resources. LIMITATIONS REASONS FOR CAUTION: This was a workshop where worldwide leading experts from a wide range of disciplines presented and discussed the evidence regarding challenges related to MRH. While each expert summarized the current literature and placed it in context, the data in a number of areas are limited and/or sparse. Equally, important areas for consideration may have been missed. Moreover, there are clear gaps in our knowledge base, which makes some conclusions necessarily speculative and warranting of further study. WIDER IMPLICATIONS: Poor MRH is a global issue that suffers from low awareness among the public, patients, and heathcare professionals. Addressing this will require a coordinated multidisciplinary approach. Addressing the significant number of knowledge gaps will require policy makers prioritizing MRH and its funding.

Early Interventional Treatment of High Output Chyle Leak After Esophagectomy is Associated With Improved Survival.

OBJECTIVE: To investigate overall survival and length of stay (LOS) associated with differing management for high output (>1 L over 24 hours) leaks (HOCL) after cancer-related esophagectomy. BACKGROUND: Although infrequent, chyle leak after esophagectomy is an event that can lead to significant perioperative sequelae. Low-volume leaks appear to respond to nonoperative measures, whereas HOCLs often require invasive therapeutic interventions. METHODS: From a prospective single-institution database, we retrospectively reviewed patients treated from 2001 to 2021 who underwent esophagectomy for esophageal cancer. Within that cohort, we focused on a subgroup of patients who manifested a HOCL postoperatively. Clinicopathologic and operative characteristics were collected, including hospital LOS and survival data. RESULTS: A total of 53/2299 patients manifested a HOCL. These were mostly males (77%), with a mean age of 62 years. Of this group, 15 patients received nonoperative management, 15 patients received prompt (<72 hours from diagnosis) interventional management, and 23 received late interventional management. Patients in the late intervention group had longer LOSs compared with early intervention (slope = 9.849, 95% CI: 3.431-16.267). Late intervention (hazard ratio: 4.772, CI: 1.384-16.460) and nonoperative management (hazard ratio: 4.731, CI: 1.294-17.305) were associated with increased mortality compared with early intervention. Patients with early intervention for HOCL had an overall survival similar to patients without chyle leaks in survival analysis. CONCLUSIONS: Patients with HOCL should receive early intervention to possibly reverse the prognostic implications of this potentially detrimental complication.

A preconception cohort study of sugar-sweetened beverage consumption and semen quality.

BACKGROUND: Dietary factors, including high sugar intake, may have adverse effects on male reproduction. Studies of the association between sugar-sweetened beverage (SSB) intake and semen quality have reported inconsistent results. OBJECTIVE: We estimated the effects of SSB consumption on semen quality in a North American preconception cohort study. METHODS: We analyzed baseline data from 690 males (n = 1,247 samples) participating in Pregnancy Study Online (PRESTO) during 2015-2022. Participants aged ≥21 years completed a baseline questionnaire on which they reported information about intake of SSBs, including sodas, energy drinks, sports drinks, and fruit juices. After enrollment, we invited U.S. participants to a semen testing substudy, in which they collected and analyzed two samples using an at-home semen testing kit. We used linear regression models to estimate adjusted percent differences (%D) and 95% confidence intervals (CI) for associations of SSB intake with semen volume, sperm concentration, total sperm count (TSC), motility, and total motile sperm count (TMSC). We used modified Poisson regression models to estimate adjusted risk ratios (RRs) and 95% CIs for the association of SSB intake with World Health Organization semen parameter cut points. RESULTS: Relative to non-consumers of SSBs, those who consumed ≥7 SSBs/week had lower semen volume (%D = -6, 95% CI: -13, 0), sperm concentration (%D = -22, 95% CI: -38, 0), TSC (%D = -22, 95% CI: -38, -2), motility (%D = -4, 95% CI: -10, 2), and TMSC (%D = -25, 95% CI: -43, -2). High SSB consumers also had greater risks of low sperm concentration (≤16 million/mL; RR = 1.89, 95% CI: 1.11, 3.21), low TSC (≤39 million; RR = 1.75, 95% CI: 0.92, 3.33), low motility (≤42%; RR = 1.23, 95% CI: 0.87, 1.75) and low TMSC (≤21 million; RR = 1.95, 95% CI: 1.12, 3.38). Associations were stronger among participants with body mass index ≥ 25 kg/m2 . CONCLUSION: Greater SSB consumption was associated with reduced semen quality in a North American preconception cohort.

Octreotide's role in the management of post-esophagectomy chylothorax.

The use of octreotide in managing intrathoracic chyle leak following esophagectomy has gained popularity in the adult population. While the benefits of octreotide have been confirmed in the pediatric population, there remains limited evidence to support its use in the adults post-esophagectomy. Thus, we performed a single-institution cohort study to characterize its efficacy. The study was performed using a prospective, single-center database, from which clinicopathologic characteristics were extracted of patients who had post-esophagectomy chyle leaks. Kaplan-Meier and multivariable Cox regression analyses were performed to investigate the effect of octreotide use on chest tube duration (CTD), hospital length of stay (LOS), and overall survival (OS). In our cohort, 74 patients met inclusion criteria, among whom 27 (36.5%) received octreotide. Kaplan-Meier revealed no significant effect of octreotide on CTD (P = 0.890), LOS (P = 0.740), or OS (P = 0.570). Multivariable Cox regression analyses further corroborated that octreotide had no effect on CTD (HR = 0.62, 95% confidence interval [CI]: 0.32-1.20, P = 0.155), LOS (HR = 0.64, CI: 0.34-1.21, P = 0.168), or OS (1.08, CI: 0.53-2.19, P = 0.833). Octreotide use in adult patients with chyle leak following esophagectomy lacks evidence of association with meaningful clinical outcomes. Level 1 evidence is needed prior to further consideration in this population.

The paternal role in pregnancy loss.

In this comprehensive review, the intricate relationship between paternal factors and pregnancy loss is examined. While pregnancy loss has historically been predominantly attributed to maternal factors, recent research underscores the significant contribution of the male partner. The review delves into various aspects of paternal influence, including paternal age, health, chromosome abnormalities, Y chromosome deletions, and sperm DNA fragmentation. Notably, advanced paternal age is found to be associated with an increased risk of recurrent pregnancy loss, shedding light on the importance of understanding the impact of aging on male fertility. Additionally, paternal health, particularly metabolic syndrome, emerges as a noteworthy factor contributing to pregnancy loss. Chromosome abnormalities in male partners, such as balanced translocations, and Y chromosome microdeletions are explored in the context of pregnancy loss risk. Moreover, the review highlights the growing body of evidence linking sperm DNA fragmentation and sperm protein abnormalities to spontaneous pregnancy loss, emphasizing the significance of sperm health in reproductive outcomes. Overall, this review provides a comprehensive overview of the multifaceted role of the male partner in pregnancy loss, calling for a more inclusive approach to pregnancy loss investigations that encompasses both maternal and paternal factors.

Systematic review and meta-analysis of serum total testosterone and luteinizing hormone variations across hospitalized Covid-19 patients.

A growing body of evidence suggests the role of male hypogonadism as a possible harbinger for poor clinical outcomes across hospitalized Covid-19 patients. Accordingly, we sought to investigate the impact of dysregulated hypothalamic-pituitary-gonadal axis on the severity of the clinical manifestations for hospitalized Covid-19 patients matched with healthy controls through a systematic review and meta-analysis. Databases were searched from inception to March 2022. A standardized mean difference (SMD) meta-analysis focused on hospitalized Covid-19 patients and healthy controls was developed for studies who reported total testosterone (TT) and luteinizing hormone (LH) levels at hospital admission. Overall, n = 18 series with n = 1575 patients between 2020 and 2022 were reviewed. A significant decrease in SMD of TT levels in Covid-19 patients compared to paired controls was observed (- 3.25 nmol/L, 95%CI - 0.57 and - 5.93). This reduction was even more consistent when matching severe Covid-19 patients with controls (- 5.04 nmol/L, 95%CI - 1.26 and - 8.82) but similar for Covid-19 survivors and non-survivors (- 3.04 nmol/L, 95%CI - 2.04 and - 4.05). No significant variation was observed for serum LH levels across studies. Patient related comorbidities, year of the pandemic, and total lymphocyte count were associated with the observed estimates. TT levels may be a useful serum marker of poor outcomes among Covid-19 patients. These findings may support the development of ad-hoc clinical trials in the Covid-19 risk-group classification and subsequent disease monitoring. The interplay between TT and immune response should be evaluated in future researches.

Endobronchial ultrasound: A novel screening test for pulmonary hypertension prior to major pulmonary surgery.

Objectives: Pulmonary hypertension (PH) is an important physiologic variable in the assessment of patients undergoing major thoracic operations but all too often neglected because of the need for right heart catheterization (RHC) due to the inaccuracy of transthoracic echocardiography. Patients with lung cancer often require endobronchial ultrasound (EBUS) as part of the staging of the cancer. We sought to investigate whether EBUS can be used to screen these patients for PH. Methods: Patients undergoing a major thoracic operation requiring EBUS for staging were included prospectively in the study. All patients had also a RHC (gold standard). We aimed to compare the pulmonary artery pressure measurements by EBUS with the RHC values. Results: A total of 20 patients were enrolled in the study. The prevalence of abnormal pulmonary artery pressure was 65% based on RHC. All patients underwent measurement of the pulmonary vascular acceleration time (PVAT) by EBUS with no adverse events. Linear regression analysis comparing PVAT and RHC showed a correlation (r = -0.059, -0.010 to -0.018, P = .007). A receiver operator characteristic curve (area under the curve = 0.736) was used to find the optimal PVAT threshold (140 milliseconds) to predict PH; this was used to calculate a positive and negative likelihood ratio following a positive diagnosis of 2.154 and 0.538, respectively. Conclusions: EBUS interrogation of pulmonary artery hemodynamic is safe and feasible. EBUS may be used as a screening test for PH in high-risk individuals.

Lung surveillance following colorectal cancer pulmonary metastasectomy: Utilization of clinicopathologic risk factors to guide strategy.

BACKGROUND: Appropriately selected patients clearly benefit from resection of colorectal cancer (CRC) pulmonary metastases (PMs). However, there remains equipoise surrounding optimal chest surveillance strategies following pulmonary metastasectomy. We aimed to identify risk factors that may inform chest surveillance in this population. METHODS: Patients who underwent CRC pulmonary metastasectomy were identified from a single institution's prospectively maintained surgical database. Clinicopathologic and genomic characteristics were collected. Patients were stratified by diagnosis of subsequent PM within 6 months of the index lung resection. Multivariate modeling was used to evaluate risk factors. RESULTS: A total of 197 patients met the study's inclusion criteria, of whom 52.3% (n = 103) developed subsequent PM, at a median of 9.51 months following the index metastasectomy. Patients with KRAS alterations (odds ratio [OR], 3.073; 95% confidence interval [CI], 1.363-6.926; P = .007), TP53 alterations (OR, 3.109; 95% CI, 1.318-7.341; P = .010) were found to be at risk of PM diagnosis within 6 months of the index metastasectomy, while those with an APC alteration (OR, .218; 95% CI, 0.080-0.598; P = .003) were protected. Moreover, patients who received systemic therapy within 3 months of the initial PM diagnosis also were more likely to develop early lung recurrence (OR, 2.105; 95% CI, 0.971-4.563; P = .059). CONCLUSIONS: Patients with KRAS alterations, TP53 alterations, and no APC alterations developed early recurrence in the lung following pulmonary metastasectomy, as did those who received chemotherapy after their initial PM diagnosis. As such, these groups benefit from early lung imaging after metastasectomy, as chest surveillance protocols should be based on patient-centered clinicopathologic and genomic risk factors.

Impact of travel distance on receipt of indicated adjuvant therapy in resected non-small cell lung cancer.

OBJECTIVE: We have previously demonstrated the negative impact of travel distance on adherence to surveillance imaging guidelines for resected non-small cell lung cancer (NSCLC). The influence of patient residential location on adherence to recommended postoperative treatment plans remains unclear. We sought to characterize the impact of travel distance on receipt of indicated adjuvant therapy in resected NSCLC. METHODS: We performed a single-institution, retrospective review of patients with stage II-III NSCLC who underwent upfront pulmonary resection, 2012-2016. Clinicopathologic and operative/perioperative details of treatment were collected. Travel distance was measured from patients' homes to the operative hospital. Our primary outcome was receipt of adjuvant systemic or radiotherapy. Travel distance was stratified as <100 or >100 miles. Multivariable logistic regression was performed. RESULTS: In total, 391 patients met inclusion criteria, with mean age of 65.9 years and fairly even sex distribution (182 women, 49.2%). Most patients were Non-Hispanic White (n = 309, 83.5%), and most frequent clinical stage was II (n = 254, 64.9%). Indicated adjuvant therapy was received by 266 (71.9%), and median distance traveled was 209 miles (interquartile range, 50.7-617). Multivariate analysis revealed that longer travel distance was inversely associated with receipt of indicated adjuvant therapy (odds ratio, 0.13; 95% confidence interval, 0.06-0.26; P < .001). In addition, Black patients were less likely to receive appropriate treatment (odds ratio, 0.05; 95% confidence interval, 0.02-0.15; P < .001). CONCLUSIONS: Travel distance >100 miles negatively impacts the likelihood of receiving indicated adjuvant therapy in NSCLC. Indications for systemic therapy in earlier staged disease are rapidly expanding, and these findings bear heightened relevance as we aim to provide equitable access to all patients.

Emergency vascular repairs in trauma: Predictors of poor prognosis and a novel scoring system.

BACKGROUND: Vascular injuries comprise 1% to 4% of all trauma patients, and there are no widely used risk-stratification tools. We sought to establish predictors of revascularization failures and compare outcomes of trauma and vascular surgeons. METHODS: We performed a single-institution, case-control study of consecutive patients with traumatic arterial injuries who underwent open repair between 2016 and 2021. Multivariable logistic regression was used to investigate covariates impacting the primary composite outcome of repair failure/revision, amputation, or in-hospital mortality. RESULTS: Among 165 patients, the median age was 34 years, 149 (90%) were male, and 99 (60%) suffered penetrating injury. Popliteal (46%) and superficial femoral (44%) arterial injuries were most common. Interposition graft/bypass was the most frequent repair (n = 107 [65%]). Revascularization failure was observed in 24 patients (15%). Compared with trauma surgeons, vascular surgeons more frequently repaired blunt injuries (66% vs. 20%, p < 0.001), anterior tibial (18% vs. 5%, p = 0.012), or tibioperoneal injuries (28% vs. 4%, p < 0.001), with a below-knee bypass (38% vs. 20%, p = 0.019). Revascularization failure occurred in 10% (9 of 93) of repairs by trauma surgeons and 21% (13 of 61) of repairs by vascular surgeons. Mangled Extremity Severity Score >8 (odds ratio, 15.6; 95% confidence interval, 4.4-55.9; p < 0.001) and concomitant laparotomy or orthopedic procedure (odds ratio, 6.7; 95% confidence interval, 1.6-28.6; p = 0.010) were independently associated with revascularization failure. A novel composite scoring system (UT Houston Score) was developed by combining Mangled Extremity Severity Score, concomitant procedure, mechanism of injury, and injury location. This score demonstrated a sensitivity of 100% with a score of 0 and a specificity of 95% with a score of >3. CONCLUSION: After traumatic arterial injury, trauma surgeons repaired less-complex injuries but with fewer revascularization failures than vascular surgeons. The UT Houston Score may be used to risk stratify patients to determine who may benefit from vascular surgery consultation. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Do resected colorectal cancer patients need early chest imaging? Impact of clinicopathologic characteristics on time to development of pulmonary metastases.

BACKGROUND AND OBJECTIVES: For patients with colorectal cancer (CRC), the lung is the most common extra-abdominal site of distant metastasis. However, practices for chest imaging after colorectal resection vary widely. We aimed to identify characteristics that may indicate a need for early follow-up imaging. METHODS: We retrospectively reviewed charts of patients who underwent CRC resection, collecting clinicopathologic details and oncologic outcomes. Patients were grouped by timing of pulmonary metastases (PM) development. Analyses were performed to investigate odds ratio (OR) of PM diagnosis within 3 months of CRC resection. RESULTS: Of 1600 patients with resected CRC, 233 (14.6%) developed PM, at a median of 15.4 months following CRC resection. Univariable analyses revealed age, receipt of systemic therapy, lymph node ratio (LNR), lymphovascular and perineural invasion, and KRAS mutation as risk factors for PM. Furthermore, multivariable regression showed neoadjuvant therapy (OR: 2.99, p < 0.001), adjuvant therapy (OR: 6.28, p < 0.001), LNR (OR: 28.91, p < 0.001), and KRAS alteration (OR: 5.19, p < 0.001) to predict PM within 3 months post-resection. CONCLUSIONS: We identified clinicopathologic characteristics that predict development of PM within 3 months after primary CRC resection. Early surveillance in such patients should be emphasized to ensure timely identification and treatment of PM.

The Association Between Insomnia, Insomnia Medications, and Erectile Dysfunction.

BACKGROUND: Sleep quality and duration have been investigated for their association with health. Insomnia affects up to one-third of adults and may impact male erectile function. In addition, medical treatments for insomnia (many of which are sedatives) may also affect erectile quality. OBJECTIVE: To investigate the association of erectile dysfunction (ED) in patients diagnosed with and treated for insomnia. DESIGN, SETTING, AND PARTICIPANTS: We utilized the IBM MarketScan (2007-2016) Commercial and Medicare Supplemental Databases (v 2.0). Age- and enrollment-matched controls were selected among patients without insomnia diagnosis or treatment. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Cox proportional hazard models were used to estimate the risk of incident ED (ie, diagnosis alone, or diagnosis and treatment with phosphodiesterase-5 inhibitors [PDE5i], intracavernous injection (ICI)/urethral suppositories, and penile prosthesis) after the diagnosis or treatment of insomnia while adjusting for relevant comorbidities. RESULTS AND LIMITATIONS: In total, 539 109 men with an insomnia diagnosis were identified. Of these men, 356 575 were also medically treated for insomnia. The mean (±standard deviation) follow-up times for patients diagnosed with insomnia and those diagnosed with and treated for insomnia were 2.8 ± 1.6 and 3.1 ± 1.8 yr, respectively. Men with insomnia were more commonly smokers and had a higher number of office visits and comorbidities than controls (p < 0.001). On an adjusted analysis, both untreated and treated insomnia were associated with increased risks of ED diagnosis (hazard ratio or HR [95% confidence interval {CI}]: 1.58 [1.54-1.62] and 1.66 [1.64-1.69], respectively; p < 0.001). Similarly, men with treated insomnia had a higher risk of having ED treated with PDE5i (HR [95% CI]: 1.52 [1.49-1.55]; p < 0.001) and ICI (HR [95% CI]: 1.32 [1.14-1.54]; p < 0.001) when compared with controls. A limitation of this study was that a lack of granularity regarding patient clinical characteristics (eg, severity of disease, laboratory data, etc.) is inherent to insurance claims data. In addition, the follow-up was limited and may affect associations at longer time points. CONCLUSIONS: In the current report, a consistent association between insomnia and ED diagnosis was identified. Men diagnosed with insomnia only were found to have a higher risk of developing ED. Moreover, men with pharmacological insomnia treatments were more often prescribed treatments for ED. Given the prevalence of insomnia, future studies are warranted to delineate the association of insomnia and its treatment with erectile function. PATIENT SUMMARY: Insomnia affects up to one-third of adults and impact male erectile function. Men only diagnosed with insomnia were found to have a higher risk of developing erectile dysfunction (ED). Moreover, men with pharmacological insomnia treatments were more often prescribed treatments for ED.
