Optimizing Longitudinal Tobacco Cessation Treatment in Lung Cancer Screening: A Sequential, Multiple Assignment, Randomized Trial.

Importance: Nearly half of the 14.8 million US adults eligible for lung cancer screening (LCS) smoke cigarettes. The optimal smoking cessation program components for the LCS setting are unclear. Objective: To assess the effect of adding a referral to prescription medication therapy management (MTM) to the tobacco longitudinal care (TLC) program among patients eligible for LCS who smoke and do not respond to early tobacco treatment and to assess the effect of decreasing the intensity of TLC among participants who do respond to early treatment. Design, Setting, and Participants: This randomized clinical trial included patients who currently smoked cigarettes daily and were eligible for LCS. Recruitment took place at primary care centers and LCS programs at 3 large health systems in the US and began in October 2016, and 18-month follow-up was completed April 2021. Interventions: (1) TLC comprising intensive telephone coaching and combination nicotine replacement therapy for 1 year with at least monthly contact; (2) TLC with MTM, MTM offered pharmacist-referral for prescription medications; and (3) Quarterly TLC, intensity of TLC was decreased to quarterly contact. Intervention assignments were based on early response to tobacco treatment (abstinence) that was assessed either 4 weeks or 8 weeks after treatment initiation. Main outcomes and Measures: Self-reported, 6-month prolonged abstinence at 18-month. Results: Of 636 participants, 228 (35.9%) were female, 564 (89.4%) were White individuals, and the median (IQR) age was 64.3 (59.6-68.8) years. Four weeks or 8 weeks after treatment initiation, 510 participants (80.2%) continued to smoke (ie, early treatment nonresponders) and 126 participants (19.8%) had quit (ie, early treatment responders). The 18 month follow-up survey response rate was 83.2% (529 of 636). Across TLC groups at 18 months follow-up, the overall 6-month prolonged abstinence rate was 24.4% (129 of 529). Among the 416 early treatment nonresponders, 6-month prolonged abstinence for TLC with MTM vs TLC was 17.8% vs 16.4% (adjusted odds ratio [aOR] 1.13; 95% CI, 0.67-1.89). In TLC with MTM, 98 of 254 participants (39%) completed at least 1 MTM visit. Among 113 early treatment responders, 6-month prolonged abstinence for Quarterly TLC vs TLC was 24 of 55 (43.6%) vs 34 of 58 (58.6%) (aOR, 0.54; 95% CI, 0.25-1.17). Conclusions and Relevance: In this randomized clinical trial, adding referral to MTM with TLC for participants who did not respond to early treatment did not improve smoking abstinence. Stepping down to Quarterly TLC among early treatment responders is not recommended. Integrating longitudinal tobacco cessation care with LCS is feasible and associated with clinically meaningful quit rates. Trial Registration: ClinicalTrials.gov Identifier: NCT02597491.

Retrograde incision from orifice (RIO) technique for endoscopic incision of ureterocele: 15 years of outcomes.

INTRODUCTION: Management of obstructing ureterocele often includes endoscopic transurethral incision (TUI) that can be challenging secondary to uncertainty in anatomic landmarks with risk of serious complications. To this end, we innovated a technique using predictable landmarks that begins endoscopic incision at the ureterocele orifice and extends retrograde proximal to the bladder neck (Figure). OBJECTIVE: With over 15 years of experience in performing this retrograde incision from orifice (RIO) technique, we aimed to examine post-operative outcomes and risk of surgical failure after RIO compared to traditional TUI techniques for ureteroceles. We hypothesized that clinical outcomes after RIO would be superior to traditional endoscopic approaches to decompression of obstructing ureterocele in infants. STUDY DESIGN: A retrospective study of patients ≤12 months old who underwent TUI ureterocele at our institution between 2007 and -2021 was conducted. Pre-, intra- and post-operative characteristics were compared between patients who underwent RIO vs non-RIO TUI. Primary outcome was post-incision febrile urinary tract infection (fUTI). Secondary outcome was a composite failure measure of fUTI, secondary surgery, de novo bladder outlet obstruction, or vesicoureteral reflux. Multivariable Cox proportional hazard models were fitted to compare the time-to-event risk of primary and secondary outcomes between groups. RESULTS: Ninety patients with 92 ureteroceles were included (49 RIO, 43 non-RIO). Median follow-up from TUI was 33 months. RIO had a shorter median operative duration (27 vs 35 min, p = 0.021). Primary and secondary outcomes were similar between groups (fUTI: 29% RIO vs 19% non-RIO, p = 0.27; composite failure 54% RIO vs 69% non-RIO, p = 0.15). In multivariable Cox proportional hazard models, there was no significant difference in risk of fUTI (RIO aHR 0.98, 95% CI 0.38-2.54, p = 0.97) or composite failure (RIO aHR 0.80, 95% CI 0.45-1.44, p = 0.46) between TUI techniques. DISCUSSION: RIO technique for TUI ureterocele is attractive in that it uses predictable anatomic landmarks making it simple to perform. In analyzing this 15-year institutional experience of TUI ureterocele, RIO showed similar success to non-RIO endoscopic incisions. This study is a retrospective, non-randomized, single-institutional study over 15 years and is therefore subject to change in surgeon practice over time and variable practices between providers. CONCLUSIONS: Given comparable success and durability over time to other TUI ureterocele techniques, and with the advantage of operator ease using consistent anatomic landmarks, RIO is a worthy option for endoscopic ureterocele decompression.

Robot-assisted Laparoscopic Pyeloplasty: Experience of a Single Pediatric Institution, Including Long-term and Safety Outcomes.

OBJECTIVE: To evaluate the efficacy and safety of robot-assisted laparoscopic pyeloplasty (RALP) and describe the short and long-term outcomes of pediatric RALP. METHODS: We retrospectively reviewed all patients ..±21 years old who underwent primary RALP from 7/2007 through 12/2019. Patients were excluded from postoperative analysis if follow-up data after stent removal was not available. The primary outcome was surgical success, defined as radiographic improvement of hydronephrosis without need for reoperation. Secondary outcomes were time to reoperation and 90-day complication rate. RESULTS: A total of 356 patients underwent primary repair of ureteropelvic junction obstruction during the study period; 29.ßpatients were limited to intraoperative data due to lack of follow-up imaging. Radiographic improvement at latest follow-up was seen in 308/327 (94.2%). Ten of 327 patients (3.1%) underwent reoperation: 7 were identified within 1 year of RALP and 3 were identified over 1 year after RALP. The median time to reoperation was 13.0 months (IQR 9.3-21.7). We defined long-term as>3 years after pyeloplasty. Over one-third (122/327, 37.3%) of the cohort had>3 years of follow-up, none of whom developed evidence of recurrent obstruction requiring reoperation beyond 3 years. Complications occurred within 90 days of surgery in 20/327 (6.1%). CONCLUSION: This largest single-institution series confirms short- and long-term surgical effectiveness and safety of RALP. Our data also indicate that most patients who needed reoperation were identified within 1 year, and reoperation more than 3 years after RALP is rare.

Increased Levels of the Acrolein Metabolite 3-Hydroxypropyl Mercapturic Acid in the Urine of e-Cigarette Users.

Carcinogen and toxicant uptake by e-cigarette users have not been fully evaluated. In the study reported here, we recruited 30 e-cigarette users, 63 nonsmokers, and 33 cigarette smokers who gave monthly urine samples over a period of 4-6 months. Their product use status was confirmed by measurements of exhaled CO, urinary total nicotine equivalents, cyanoethyl mercapturic acid (CEMA), and total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol. Urinary biomarkers of exposure to the carcinogens acrolein (3-hydroxypropyl mercapturic acid, 3-HPMA), benzene (S-phenyl mercapturic acid, SPMA), acrylonitrile (CEMA), and a combination of crotonaldehyde, methyl vinyl ketone, and methacrolein (3-hydroxy-1-methylpropyl mercapturic acid, HMPMA) were quantified at each visit. Data from subject visits with CEMA > 27 pmol/mL were excluded from the statistical analysis of the results because of possible unreported exposures to volatile combustion products such as secondhand cigarette smoke or marijuana smoke exposure; this left 22 e-cigarette users with 4 or more monthly visits and all 63 nonsmokers. Geometric mean levels of 3-HPMA (1249 versus 679.3 pmol/mL urine) were significantly higher (P = 0.003) in e-cigarette users than in nonsmokers, whereas levels of SPMA, CEMA, and HMPMA did not differ between these two groups. All analytes were significantly higher in cigarette smokers than in either e-cigarette users or nonsmokers. The results of this unique multimonth longitudinal study demonstrate consistent significantly higher uptake of the carcinogen acrolein in e-cigarette users versus nonsmokers, presenting a warning signal regarding e-cigarette use.

InCISE: Instrument for Comprehensive Incisional and Surgical Evaluation.

OBJECTIVE: The evaluation of healing after head and neck surgery is currently qualitative and non-standardized, limiting the quality of surgical healing assessments in clinical and research settings. We sought to develop an objective, standardized wound assessment score, and hypothesize that a reliable instrument can be developed to evaluate head and neck surgical wounds. METHODS: A prospective cohort study was conducted in a tertiary-care, academic head and neck surgery practice. Patients undergoing head and neck surgery were enrolled. A digital photograph protocol was developed for evaluating healing surgical wounds. A panel of experts developed and refined a wound healing score and established reliability, reproducibility, internal consistency, and validity of the score. RESULTS: InCISE: Instrument for comprehensive incisional and surgical evaluation was created. The utility of our wound healing score was assessed using classical test theory. We performed the major steps of establishing reliability in head and neck surgeons: (1) internal consistency (Cronbach's α = 0.81), (2) inter-observer reliability (intra-class correlation = 0.76), and (3) intra-rater reliability (intra-class correlation = 0.87), and content validity (through focus groups). Our composite measure was found to have strong internal consistency, inter-rater reliability, and intra-rater reliability. Preliminary work suggests criterion validity via associations with physical health related quality of life (SF-12). CONCLUSION: A wound healing score for head and neck surgery, InCISE, has been developed and is reliable, reproducible, and consistent. Although content validity is present and criterion validity is suggested, work continues to establish validity in this instrument to allow for expanded clinical and research use.

Adult Hematology/Oncology Patient Perspectives on Telemedicine Highlight Areas of Focus for Future Hybrid Care Models.

Introduction: Telemedicine use expanded rapidly during the COVID-19 pandemic, but publications analyzing patient perspectives on telemedicine are few. We aimed to study whether patient perspectives offer insights into how best to utilize telemedicine in the future for hematology and cancer care. Methods: A modified Telemedicine Satisfaction and Usefulness Questionnaire (TSUQ) was sent to adult hematology/oncology outpatients at the University of Minnesota Masonic Cancer Clinic who had ≥1 prior phone and/or video visit between March 15, 2020, and March 31, 2021. Two focus groups were subsequently conducted with volunteers who completed the survey. We evaluated dichotomized TSUQ items using logistic regression, and focus group data were analyzed qualitatively using constant comparison analysis. Results: Of 7,848 invitations, 588 surveys were completed. Focus groups included 16 survey respondents. Most respondents found telemedicine satisfactory, easy to use, and convenient, with the majority preferring a hybrid approach going forward. Oncology patients, females, and higher income earners endorsed decreased telemedicine satisfaction. Concerns were voiced about fewer in-person interactions, communication gaps, and provider style variability. Discussion: Adult hematology/oncology patients had varied perspectives on telemedicine utilization success based on gender, income, and disease burden, suggesting that a one-size-fits-all approach, as was implemented nearly universally during the COVID-19 pandemic, is not an ideal approach for the long term. Given that telemedicine use is likely to remain in some form in most centers, our findings suggest that a nuanced and tailored approach for some patient subgroups and using feedback from patients will make implementation more effective.

Latent constructs identified in older individuals who smoke cigarettes and are eligible for lung cancer screening: Factor analysis of baseline data from the PLUTO smoking cessation trial.

Introduction: Lung cancer screening (LCS) combined with smoking cessation intervention is currently recommended for older individuals with a history of heavy smoking. Tailoring tobacco treatment for this patient population of older, people who smoke (PWS) may improve cessation rates while efficiently using limited smoking cessation resources. Although some older people who smoke will need more intensive treatment to achieve sustained abstinence, others may be successful with less intensive treatment. A framework to identify them a priori would be helpful to distribute smoking cessation resources accordingly. Methods: Baseline demographic, smoking, and health data are reported from a randomized clinical trial of longitudinal smoking cessation interventions delivered in the setting of LCS. Candidate variables were factor analyzed to identify latent factors, or constructs, to identify subgroups of older participants among the heterogenous population of older people who smoke. Results: We identified three factor-derived constructs: self-reported health status, heaviness of smoking, and nicotine dependence. Nicotine dependence was moderately correlated with both of the other two factors. Conclusions: This factor analysis of baseline participant characteristics identified a set of latent constructs - based on a few practical clinical variables -- that can be used to classify the heterogenous population of older people who smoke to identify. We propose this framework to identify subgroups of people who smoke who might successfully quit with less intense treatment at the time of lung cancer screening.

Prospective Trial of Neutrophil/Lymphocyte Ratio and Other Blood Counts as Biomarkers of Survival among Patients with High-Grade Soft Tissue Sarcomas Treated with Pegylated Liposomal Doxorubicin and Ifosfamide.

Several studies have reported an association between levels of circulating blood cells, in particular the neutrophil to lymphocyte ratio (absolute neutrophil count (ANC)/absolute lymphocyte count (ALC)) and outcomes in patients with cancer. In the current study, the association between lymphocyte, neutrophil, monocyte, and platelet counts and survival was examined in a prospective trial of preoperative pegylated-liposomal doxorubicin and ifosfamide for high-grade soft-tissue sarcomas. A statistically significant association between overall survival, but not progression free-survival, was observed with the ANC/ALC ratio at a cutoff value of ≥2 and a statistically significant trend using a cutoff of ≥5. Our results suggest that a balance between the lymphocyte count and the number of circulating myeloid cells that can suppress lymphocyte function may be predictive of survival in patients with soft-tissue sarcomas. Future research should therefore examine the role of lymphocyte-myeloid cell balance in sarcoma biology.

Prospective Trial of Monocyte Count as a Biomarker of Hand-Foot Syndrome Among Patients With Soft Tissue Sarcomas Treated With Pegylated Liposomal Doxorubicin and Ifosfamide.

Pegylated liposomal doxorubicin (PLD) is widely used and can be used for prolonged periods, with the limiting toxicity usually being hand-foot syndrome (HFS). The pharmacokinetics of PLD is variable between patients, leading to variability in the risk of developing HFS. Dosing based on body surface area does not decrease variability in PLD clearance; thus, other predictive markers could be useful. The peripheral blood absolute monocyte count (AMC) has been suggested as a possible marker of both reticuloendothelial system function and PLD pharmacokinetics. The present study examined the AMC as a potential predictive biomarker in a prospective trial of pre-operative PLD combined with ifosfamide in soft tissue sarcomas (STSs). While our results suggest a relationship between pre-treatment AMC and PLD-induced HFS, the association did not reach statistical significance. The clinical utility of the AMC as a predictor of PLD-induced HFS appears limited, at least when given with ifosfamide.

Increased acrolein-DNA adducts in buccal brushings of e-cigarette users.

DNA adducts are central in the mechanism of carcinogenesis by genotoxic agents. We compared levels of a DNA adduct of acrolein, a genotoxic carcinogen found in e-cigarette vapor, in oral cell DNA of e-cigarette users and non-users of any tobacco or nicotine product. e-Cigarette users and non-users visited our clinic once monthly for 6 months, and oral brushings and urine samples were collected. For this study, we analyzed oral cell DNA adducts from three monthly visits in e-cigarette users and non-users as confirmed by urinary cyanoethyl mercapturic acid and total nicotine equivalents. DNA was isolated from the oral brushings and analyzed by a validated liquid chromatography-nanoelectrospray ionization-high resolution tandem mass spectrometry method for the acrolein DNA adduct 8R/S-3-(2'-deoxyribos-1'-yl)-5,6,7,8-tetrahydro-8-hydroxypyrimido[1,2-a]purine-10-(3H)-one (γ-OH-Acr-dGuo). The median value of this DNA adduct in the e-cigarette users was 179 fmol/µmol dGuo (range 5.0 - 793 fmol/µmol dGuo) while that for non-users was 21.0 fmol/µmol dGuo (range 5.0 - 539 fmol/µmol dGuo), P = 0.001. These results demonstrate for the first time that e-cigarette users have elevated levels of a carcinogen-DNA adduct in their oral cells.

Safety and Efficacy of Robot-Assisted Laparoscopic Pyeloplasty Compared to Open Repair in Infants under 1 Year of Age.

PURPOSE: Robot-assisted laparoscopic pyeloplasty (RALP) use in children has increased, though many centers still favor open pyeloplasty (OP) in infants. This study aims to compare safety and efficacy of RALP and OP in infants. MATERIALS AND METHODS: A single-institution, retrospective cohort study of infants <1 year of age who underwent primary RALP or OP between January 2009 and June 2020 was performed. Primary outcomes were intraoperative and 30-day complications, postoperative radiographic improvement at last clinic visit, and operative failure leading to redo pyeloplasty. Multivariable logistic regression was performed for 30-day complications to adjust for demographic variation between groups. Survival analysis was performed to compare time to diagnosis of operative failure leading to redo pyeloplasty. RESULTS: Among 204 patients, 121 underwent OP and 83 underwent RALP (74.5% male). RALP patients were older (median 7.2 vs 2.9 months, p <0.001) and larger (median 8.2 vs 5.9 kg, p <0.001) than OP patients. Radiographic improvement was seen in 91.1% of RALP patients and 88.8% of OP patients at last visit. Median (interquartile range) followup in months was 24.4 (10.8-50.3) for the full cohort. In adjusted analysis, the odds of a 30-day complication (OR 0.40, 95% CI 0.08-2.00) was lower for RALP compared to OP, though not statistically significant. In survival analysis, there was no difference in time to diagnosis of operative failure and redo pyeloplasty between groups (p=0.65). CONCLUSIONS: RALP is a safe and effective alternative to OP for infants, with comparable intraoperative and 30-day complications, radiographic improvement at last followup, and risk of pyeloplasty failure.

Characterization of Baseline Temperature Characteristics Using Thermography in The Clinical Setting.

BACKGROUND: Thermography is a diagnostic method based on the ability to record infrared radiation emitted by the skin and is unique in its ability to accurately show physiological and/or pathological cutaneous temperature changes in a non-invasive way. This method can be used to indirectly assess changes or impairments in cutaneous perfusion. Significant technological advancements have allowed thermography to be more commonly utilized by clinicians, yet a basic consensus of patient characteristics that may affect temperature recordings is not established. MATERIALS AND METHODS: We evaluated cutaneous temperature in a cohort of outpatients to understand what factors, including tobacco use and other high-risk characteristics, contribute to cutaneous tissue perfusion as measured by thermography. Participants were prospectively enrolled if they were a combustible cigarette smoker, an electronic cigarette (e-cigarette) user, or a never smoker. Standardized thermographic images of the subject's facial profiles, forearms, and calves were taken and demographic characteristics, medical comorbidities, and tobacco product use were assessed. These variables were statistically tested for associations with temperature at each anatomic site. RESULTS: We found that gender had a significant effect on thermographic temperature that differed by anatomic site, and we found a lack of significant difference in thermographic temperature by race. Our regression analysis did not support significant differences in thermographic temperatures across smoking groups, while there was a trend for decreased perfusion in smokers relative to non-smokers and e-cigarette users relative to non-smokers. CONCLUSION: Thermographic imaging is a useful tool for clinical and research use with consideration of sex and other perfusion-affecting characteristics.

The Use of the Video, "Dear 16-Year-Old Me," as a Melanoma Education Tool in Ambulatory Dermatology.

BACKGROUND: Skin cancer continues to be the most common cancer in the United States. The rise of social media platforms and internet use offers an opportunity to present health information through video-based education. The video "Dear 16-Year-OldMe," addresses the risks associated with tanning and sun exposure, the importance of practicing sun protection, and shares stories from melanoma survivors. OBJECTIVE: To evaluate the video "Dear 16-Year-Old Me," as a patient education tool in dermatology clinics and to investigate whether viewing a short educational video can change knowledge about skin cancer risks and intention to improve skin cancer prevention behavior. PATIENTS AND METHODS/MATERIALS AND METHODS/METHODS: English-speaking clinic patients between the ages of 14 to 45 years old were recruited. Exclusion criteria include both a personal or family history of skin cancer, dysplastic nevi, or other medical comorbidities. Forty-five participants agreed to participate; 38 were eligible for analysis. RESULTS: Comparison of prevideo and postvideo responses demonstrated a statistically significant reduction in participants reporting they were likely to tan outdoors (p-value = .001). A significant increase was observed in the reported likelihood to have a professional skin examination (p-value < .001) or self-examination (p-value < .001) in the future. CONCLUSION: and Relevance: Viewing "Dear 16-Year-Old Me," resulted in reported participant changes in intention to tan outdoors and participate in skin surveillance. Although these are encouraging results, future studies with a comparison group are needed to elucidate whether these results correspond to changes in behavior. In the age of viral videos and readily accessible health information via the internet, continued investigation of video media on patient health behaviors should be pursued.

Robot-assisted laparoscopic urologic surgery in infants weighing ≤10 kg: A weight stratified analysis.

INTRODUCTION: Robot-assisted laparoscopic (RAL) urologic surgery is widely used in pediatric patients, though less commonly in infants. There are small series demonstrating safety and efficacy in infants, however, stratification by infant size has rarely been reported. Whether a cut-off weight, below which RAL surgery is not technically feasible, safe, or efficacious has not be determined. OBJECTIVE: To assess safety and efficacy of RAL urologic procedures in infants <1 year of age, weighing ≤10 kg. STUDY DESIGN: A single-institution retrospective cohort study of patients <1 year of age, and ≤10 kg undergoing RAL pyeloplasty (RALP) or RAL ipsilateral ureteroureterostomy (RALUU) between January 2011 and September 2020 was performed. Demographic, operative, and post-operative data were extracted from the medical record. Patients were stratified by post-hoc weight quartiles. Outcomes, including operative time, total OR time, estimated blood loss (EBL), post-operative length of stay (LOS), post-operative radiographic improvement, and 30-day complications were assessed by weight quartile for each procedure. The Kruskal-Wallis rank test was used to assess differences in continuous outcomes between weight quartiles and Pearson's Chi-squared test was used for categorical outcomes. RESULTS: Of 696 RAL urologic surgeries performed, 101 met eligibility criteria. Median (IQR) age of patients was 7.2 (6.0-9.2) months with median weight of 8.0 (7.2-8.9) kg. The lowest weight was 5.5 kg. Procedures performed included 79 RALPs (78.2%), 22 RALUUs (21.8%). We identified 97 patients (94%) with post-operative imaging, with radiographic improvement in 92%. When stratified by weight quartile, there was no difference between groups in median operative time, total OR time, LOS, EBL, or post-operative radiographic improvement for both RALP and RALUU. Post-operative complications were assessed based on Clavien-Dindo classification with the majority of complications (9/12, 75%) in the >50th percentile weight groups. DISCUSSION: To our knowledge, this is the largest published series of infant RAL urologic procedures, with similar rates of radiographic improvement and post-operative complications to prior published series. There are few prior series of RALP and RALUU in infants ≤10 kg, and we show comparable outcomes regardless of patient weight. Our study is limited by the inherent biases of retrospective studies. CONCLUSION: RAL urologic surgery is technically feasible, safe, and efficacious in infants ≤10 kg, without worse outcomes as weight decrease. A cut-off weight, below which RAL surgery should not be performed has yet to be identified.

Self-reported exercise capacity among current smokers eligible for lung cancer screening: Distribution and association with key comorbidities.

ONE CONCERN: as lung cancer screening (LCS) is implemented is that patients will be screened who are too ill to benefit. Poor exercise capacity (EC) predicts adverse outcomes following lung resection. OBJECTIVE: Describe the distribution of EC among smokers eligible for LCS and examine associations with comorbidities. METHODS: Cross-sectional analysis of baseline data from a randomized controlled trial of tobacco treatment in the context of LCS. Participants responded regarding limitations in moderate activities, ability to climb stairs, and frequency of dyspnea on a scale from never/almost never to all or most of the time. Responses were assigned a numeric score and summed to categorize exercise limitation. Associations between poor EC and key comorbidities were examined using adjusted logistic regression. RESULTS: 660 participants completed a survey with the following characteristics: 64.4% male, 89.5% white, mean age 64.5. Overall EC categories were: good 39.0%, intermediate 41.6%, and poor 19.4%.  Prevalence of poor EC was higher among patients with COPD (OR 4.62 95%CI 3.05-7.02), heart failure (OR 3.07 95%CI 1.62-5.82) and cardiovascular disease (OR 2.24, 95%CI 1.45-3.47), and was highest among patients with multimorbidity. Among patients with COPD and heart failure, 57% had poor and 0% had good EC. In adjusted logistic regression, only COPD and Charlson comorbidity index remained significantly associated with poor EC. CONCLUSIONS: Many patients eligible for LCS reported poor EC, with increased odds of poor EC among patients with comorbidities. More research is needed to determine how to best integrate EC and comorbidity into eligibility and shared decision-making conversations.

The New Normal? Patient Satisfaction and Usability of Telemedicine in Breast Cancer Care.

BACKGROUND: Telemedicine was adopted to minimize exposure risks for patients and staff during the coronavirus disease 2019 pandemic. This study measured patient satisfaction and telemedicine usability in breast cancer care. METHODS: Adult breast cancer patients who had a telemedicine visit at a single academic institution (with surgical, radiation, or medical oncology) from 15 June 2020 to 4 September 2020 were surveyed anonymously. Patient and cancer characteristics were collected, and patient satisfaction and telemedicine usability were assessed using a modified Telehealth Usability Questionnaire with a 7-point Likert scale. Associations of satisfaction and usability with patient characteristics were analyzed using Wilcoxon rank-sum and Kruskal-Wallis tests. RESULTS: Of 203 patients who agreed to be contacted, 78 responded, yielding a response rate of 38%. The median age of the respondents was 63 years (range 25-83 years). The majority lived in an urban area (61%), were white (92%), and saw a medical oncologist (62%). The median patient satisfaction score was 5.5 (interquartile range [IQR] 4.25-6.25). The median telemedicine usability score was 5.6 (IQR 4.4-6.2). A strong positive correlation was seen between satisfaction and usability, with a Spearman correlation coefficient (ρ) of 0.80 (p < 0.001). Satisfaction and usability scores did not vary significantly according to patient age, race, location of residence, insurance status, previous visit commute time, oncology specialty seen, prior telemedicine visits, or whether patients were actively receiving cancer treatment. CONCLUSIONS: Breast cancer patients were satisfied with telemedicine and found it usable. Patient satisfaction and telemedicine usability should not limit the use of telemedicine in future post-pandemic breast cancer care.

Impact of nicotine reduction in cigarettes on smoking behavior and exposure: Are there differences by race/ethnicity, educational attainment, or gender?

BACKGROUND: Lowering nicotine in cigarettes may reduce smoking prevalences; however, it is not known whether an immediate or gradual reduction in nicotine is the optimal approach for all population groups. OBJECTIVES: We examined whether the optimal approach to nicotine reduction depended on the education, gender, or race of people who smoke and whether the optimal approach differentially benefited people who smoke based on their education, gender, or race. METHODS: Secondary analysis was conducted on a randomized clinical trial (N = 1250) comparing (1) immediate reduction from 15.5 to 0.4 mg of nicotine per gram of tobacco(mg/g);(2) gradual reduction to 0.4 mg/g;(3) control group with normal nicotine cigarettes(15.5 mg/g). Outcomes included cigarettes per day(CPD), carbon monoxide(CO), total nicotine equivalents(TNE), 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol and its glucuronides(NNAL), phenanthrene tetraol(PheT), N-Acetyl-S-(2-cyanoethyl)-l-cysteine(CEMA). Data were analyzed as area under the curve(AUC). RESULTS: Results were presented by education (High school[HS] or less n = 505, more than HS n = 745), gender (males n = 701, females n = 549), and race (Black participants n = 373,White participants n = 758). Regardless of education, gender, and race, CPD, CO, TNE, NNAL, PheT, and CEMA were lower in immediate versus gradual nicotine reduction. Comparing immediate versus the control, outcomes were lower for all subgroups; however, the magnitude of the effect for TNE varied by race. Specifically, geometric mean of the AUC of TNE in immediate versus gradual was 49 % lower in Black participants and 61 % lower in White participants (p-value = 0.047). CONCLUSIONS: Immediately reducing nicotine in cigarettes has the potential to benefit people who smoke across lower and higher educational attainment, male and female gender, and Black and White race.

Challenging proximal hypospadias repairs: An evolution of technique for two stage repairs.

INTRODUCTION: Proximal hypospadias repair remains challenging. Our approach to the first stage of two-stage proximal hypospadias repairs has evolved from using Byars' flaps to preputial inlay grafts in anatomically suitable cases and pedicled preputial flaps in more complex repairs. We reviewed our outcomes, hypothesizing that inlay grafts and pedicled preputial flaps were associated with lower complication risks than Byars' flaps. STUDY DESIGN: A single institution, retrospective, cohort study of consecutive two-stage, primary, proximal hypospadias repairs performed from 2007 to 2017 was conducted. Patients with <6 months follow-up and incomplete operative reports were excluded. Risk of complications (fistula, dehiscence, diverticulum, meatal stenosis, stricture) were evaluated following urethroplasty and stratified by first-stage repair technique. As technique refinements have been made since 2012, comparisons between two temporal subgroups (those who underwent repair in 2007-2012 and in 2013-2017) were made. RESULTS: 78 of 127 patients met inclusion criteria. Overall complication rate was 47% (Summary Table). Median follow-up was 25.4 months (range 6.4-128.5 months) after urethroplasty. Pedicled preputial flaps (hazards ratio [HR] 0.30; 95% Confidence Interval [CI] 0.14-0.65) and inlay grafts (HR 0.32; 95% CI 0.11-0.95) were associated with lower complication risks compared to Byars' flaps (Summary Table). Median time to complication was significantly shorter for Byars' flaps (5.7 months) than for inlay grafts (40.6 months) and pedicled preputial flaps (79.2 months) by Kaplan Meier analysis. Temporal subgroup comparisons showed that overall complication rates decreased from 70% to 31% (p = 0.001), but differences in complication rates by first-stage technique were not statistically significant. DISCUSSION: In our cohort, repairs with Byars' flaps had the highest complication rate, which is consistent with our observations that urethras tubularized from Byars' flaps lack appropriate backing and are hypermobile and irregular. To overcome these shortcomings, modifications were made to our approach to two-stage proximal hypospadias repairs with the use of inlay grafts and pedicled preputial flaps quilted to the underlying corporal bodies to optimize the stability of the urethral plate. Our preliminary results are promising. CONCLUSION: Approach to the first stage of two-stage repairs affects outcomes. Pedicled preputial flaps and inlay grafts were associated with lower complication risks than Byars' flaps. Refinement of technique and patient selection may have resulted in fewer complications in the short term. However, long-term follow-up is needed.
