ObjectivesTechnical limitations of ureteroscopic (URS) biopsy has been considered responsible for substantial upgrading rate in upper tract urothelial carcinoma (UTUC). However, the impact of tumor specific factors for upgrading remain uninvestigated.MethodsPatients who underwent URS biopsy were included between 2005 and 2020 at 13 institutions. We assessed the prognostic impact of upgrading (low‐grade on URS biopsy) versus same grade (high‐grade on URS biopsy) for high‐grade UTUC tumors on radical nephroureterectomy (RNU) specimens.ResultsThis study included 371 patients, of whom 112 (30%) and 259 (70%) were biopsy‐based low‐ and high‐grade tumors, respectively. Median follow‐up was 27.3 months. Patients with high‐grade biopsy were more likely to harbor unfavorable pathologic features, such as lymphovascular invasion (p < 0.001) and positive lymph nodes (LNs; p < 0.001). On multivariable analyses adjusting for the established risk factors, high‐grade biopsy was significantly associated with worse overall (hazard ratio [HR] 1.74; 95% confidence interval [CI], 1.10–2.75; p = 0.018), cancer‐specific (HR 1.94; 95% CI, 1.07–3.52; p = 0.03), and recurrence‐free survival (HR 1.80; 95% CI, 1.13–2.87; p = 0.013). In subgroup analyses of patients with pT2‐T4 and/or positive LN, its significant association retained. Furthermore, high‐grade biopsy in clinically non‐muscle invasive disease significantly predicted upstaging to final pathologically advanced disease (≥pT2) compared to low‐grade biopsy.ConclusionsHigh tumor grade on URS biopsy is associated with features of biologically and clinically aggressive UTUC tumors. URS low‐grade UTUC that becomes upgraded to high‐grade might carry a better prognosis than high‐grade UTUC on URS. Tumor specific factors are likely to be responsible for upgrading to high‐grade on RNU.

Background: Septal reduction therapy (SRT) in patients with intractable symptoms from obstructive hypertrophic cardiomyopathy (oHCM) is associated with variable morbidity and mortality. The VALOR-HCM trial (A Study to Evaluate Mavacamten in Adults with Symptomatic Obstructive Hypertrophic Cardiomyopathy Who Are Eligible for Septal Reduction Therapy) examined the effect of mavacamten on the need for SRT through week 32 in oHCM. Methods: A double-blind randomized placebo-controlled multicenter trial at 19 US sites included patients with oHCM on maximal tolerated medical therapy referred for SRT with left ventricular outflow tract gradient ≥50 mm Hg at rest or provocation (enrollment, July 2020–October 2021). The group initially randomized to mavacamten continued the drug for 32 weeks, and the placebo group crossed over to dose-blinded mavacamten from week 16 to week 32. Dose titrations were based on investigator-blinded echocardiographic assessment of left ventricular outflow tract gradient and left ventricular ejection fraction. The principal end point was the proportion of patients proceeding with SRT or remaining guideline eligible at 32 weeks in both treatment groups. Results: From the 112 randomized patients with oHCM, 108 (mean age, 60.3 years; 50% men; 94% in New York Heart Association class III/IV) qualified for week 32 evaluation (56 in the original mavacamten group and 52 in the placebo cross-over group). After 32 weeks, 6 of 56 patients (10.7%) in the original mavacamten group and 7 of 52 patients (13.5%) in the placebo cross-over group met SRT guideline criteria or elected to undergo SRT. After 32 weeks, a sustained reduction in resting left ventricular outflow tract gradient (−33.0 mm Hg [95% CI, −41.1 to −24.9]) and Valsalva left ventricular outflow tract gradient (−43.0 mm Hg [95% CI, −52.1 to −33.9]) was observed in the original mavacamten group. A similar reduction in resting (−33.7 mm Hg [95% CI, −42.2 to −25.2]) and Valsalva (−52.9 mm Hg [95% CI, −63.2 to −42.6]) gradients was quantified in the cross-over group after 16 weeks of mavacamten. After 32 weeks, improvement by ≥1 New York Heart Association class was observed in 48 of 53 patients (90.6%) in the original mavacamten group and 35 of 50 patients (70%) after 16 weeks in the cross-over group. Conclusions: In severely symptomatic patients with oHCM, 32 weeks of mavacamten treatment showed sustained reduction in the proportion proceeding to SRT or remaining guideline eligible, with similar effects observed in patients who crossed over from placebo after 16 weeks.

Background Our goal was to compare the updated European Society of Gastrointestinal Endoscopy (ESGE) and United States Multi-Society Task Force on Colorectal Cancer (USMSTF) high risk groups in predicting metachronous advanced neoplasia on first follow-up colonoscopy and long-term colorectal cancer (CRC). Methods We compared advanced metachronous neoplasia risk (serrated polyps ≥ 1 cm or with dysplasia, advanced adenomas [≥ 1 cm, villous, high grade dysplasia], CRC) on first surveillance colonoscopy in patients with high risk findings according to ESGE versus USMSTF guidelines. We also compared the positive and negative predictive values (PPV, NPV) of both guidelines for metachronous neoplasia. Results The risk for metachronous neoplasia in our sample (n = 20 458) was higher in the high risk USMSTF (3 year) (13.6 %; 95 %CI 12.3–14.9) and ESGE groups (13.6 %; 95 %CI 12.3–15.0) compared with the lowest risk USMSTF (5.1 %; 95 %CI 4.7–5.5; P < 0.001) and ESGE categories (6.3 %; 95 %CI 6.0–6.7; P < 0.001), respectively. Adding other groups such as USMSTF 5–10-year and 3–5-year groups to the 3-year category resulted in minimal change in the PPV and NPV for metachronous advanced neoplasia. High risk ESGE (hazard ratio [HR] 3.03, 95 %CI 1.97–4.65) and USMSTF (HR 3.07, 95 %CI 2.03–4.66) designations were associated with similar long-term CRC risk (CRC per 100 000 person-years: USMSTF 3-year group 3.54, 95 %CI 2.68–4.68; ESGE high risk group: 3.43, 95 %CI 2.57–4.59). Conclusion Performance characteristics for the ESGE and USMSTF recommendations are similar in predicting metachronous advanced neoplasia and long-term CRC. The addition of risk groups, such as the USMSTF 5–10-year and 3–5-year groups to the USMSTF 3-year category did not alter the PPV or NPV significantly.

Introduction: During the early phase of the coronavirus disease 2019 (COVID-19), remdesivir was only approved for hospitalized patients. Our institution developed hospital-based, outpatient infusion centers for selected hospitalized patients with COVID-19 who had clinical improvement to allow for early dismissal. The outcomes of patients who transitioned to complete remdesivir in the outpatient setting were examined. Methods: Retrospective study of all hospitalized adult patients with COVID-19 who received at least one dose of remdesivir from 11/6/2020 to 11/5/2021 at one of the Mayo Clinic hospitals. Results: Among 3,029 hospitalized patients who received treatment with remdesivir for COVID-19, the majority (89.5%) completed the recommended the five-day course. Among them, 2,169 (80%) completed treatment during hospitalization, while 542 (20.0%) patients were dismissed to complete remdesivir in outpatient infusion centers. Patients who completed the treatment in the outpatient setting had lower odds of death within 28 days (aOR 0.14, 95% CI 0.06-0.32, p<0.001). However, their rate of subsequent hospital encounters within 30 days was higher (aHR 1.88, 95% CI 1.27-2.79, p=0.002). Among patients treated with remdesivir only in the inpatient setting, the adjusted odds of death within 28 days were significantly higher among those who did not complete the 5-day course of remdesivir (aOR 2.07, 95% CI 1.45-2.95, p<0.001). Conclusions: This study describes the clinical outcomes of a strategy of transitioning remdesivir therapy from inpatient to outpatient among selected patients. Mortality was lower among patients who completed the 5-day course of remdesivir.

In most patients with mitral valve prolapse (MVP) without severe mitral regurgitation (MR), left ventricular (LV) function is preserved. There are, however, patients with MVP who have unexplained LV dilatation and/or decreased LV function. An association between MVP and sudden cardiac death has also been reported. LV size and function may be affected by the type of MVP, severity of regurgitation, and cause of MVP (myxomatous degeneration versus fibroelastic deficiency). There is increasing evidence suggesting an intrinsic cardiomyopathy associated with MVP. The cardiomyopathy associated with MVP can also affect the right ventricle (RV). Although the impact on ventricular dimensions and function are usually subtle, these abnormalities can affect clinical and echocardiographic estimation of the severity of MR and may thus have an impact on therapeutic decisions. Particularly in patients with the most extreme forms of MVP (Barlow disease), and in patients with Marfan syndrome or other connective tissue disorders, a cardiomyopathy affecting the LV and RV may thus occur occasionally. A better understanding of LV impairment associated with MVP is important for risk assessment and clinical decision-making.

Background: Clinical management guidelines (CMGs) are decision support tools for patient care used by professionals, patients, and family caregivers. Since clinical experts develop numerous CMGs, their technical language hinders comprehension and access by nonmedical stakeholders. Additionally, the views of affected individuals and their families are often not incorporated into treatment guidelines. We developed an adequate methodology for addressing the needs and preferences of family and professional stakeholders regarding CMGs, a recently developed protocol for managing congenital disorders of glycosylation (CDG), a family of rare metabolic diseases. We used the CDG community and phosphomannomutase 2 (PMM2)-CDG CMGs as a pilot to test and implement our methodology. Results: We listened to 89 PMM2-CDG families and 35 professional stakeholders and quantified their CMG-related needs and preferences through an electronic questionnaire. Most families and professionals rated CMGs as relevant (86.5% and 94.3%, respectively), and valuable (84.3% and 94.3%, respectively) in CDG management. The most identified challenges were the lack of CMG awareness (50.6% of families) and the lack of plain language CMG (39.3% of professionals). Concordantly, among families, the most suggested solution was involving them in CMG development (55.1%), while professionals proposed adapting CMGs to include plain language (71.4%). Based on these results, a participatory framework built upon health literacy principles was created to improve CMG comprehension and accessibility. The outputs are six complementary CMG-related resources differentially adapted to the CDG community’s needs and preferences, with a plain language PMM2-CDG CMG as the primary outcome. Additionally, the participants established a distribution plan to ensure wider access to all resources. Conclusions: This empowering, people-centric methodology accelerates CMG development and accessibility to all stakeholders, ultimately improving the quality of life of individuals living with a specific condition and raising the possibility of application to other clinical guidelines.

Patients with adolescent idiopathic scoliosis (AIS) often have reduced sagittal thoracic kyphosis (hypokyphosis) and cervical lordosis causing an uneven distribution of physiologic load. However, the long-term consequences of hypokyphosis in AIS patients have not been previously documented. To evaluate whether uneven load distribution leads to future complications in patients with AIS, we conducted a retrospective chart review and subsequently surveyed 180 patients treated for idiopathic scoliosis between 1975 and 1992. These patients all had a minimum follow-up time of 20 years since their treatment. We observed a ten-fold increase in the incidence of anterior cervical discectomy and fusion (ACDF) compared to reported rates in the non-pathologic population. Out of the 180 patients, 33 patients met the criteria and returned for follow-up radiographs. This population demonstrated a statistically significant increased rate of cervical osteoarthritis and disc degeneration. Overall, our study suggests that hypokyphosis in patients with AIS presents with increased rates of cervical spine degeneration and dysfunction, suggesting that these patients may require additional follow-up and treatment.

Summary Esophageal adenocarcinoma (EAC) develops in a step-wise manner, from low-grade dysplasia (LGD) to high-grade dysplasia (HGD), and ultimately to invasive EAC. However, there remains diagnostic uncertainty about LGD and its risk of progression to HGD/EAC. The aim is to investigate the role of Ki-67, immune-histochemical marker of proliferation, surface expression in patients with confirmed LGD, and risk stratify progression to HGD/EAC. A retrospective cohort study was conducted. Patients with confirmed LGD and indefinite for dysplasia (IND), with a mean follow-up of ≥1 year, were included. Pathology specimens were stained for Ki-67 and analyzed for evidence of surface expression. Our results reveal that 29% of patients with confirmed LGD who stained positive with Ki-67 progressed to HGD/EAC as opposed to none (0%) of the patients who stained negative, a statistically significant result (P = 0.003). Similarly, specimens from patients with IND were stained and analyzed revealing a nonsignificant trend toward a higher rate of progression for Ki-67 positive cases versus Ki-67 negative, 30% versus 21%, respectively. Ki-67 expression by itself can identify patients with LGD at a high risk of progression.

307 Background: In the US, more than 12,000 people die from ovarian cancer annually. Although new treatments have recently become available, ovarian cancer care delivery remains suboptimal. The Association of Community Cancer Centers (ACCC) developed a series of initiatives to improve the quality of care for patients with ovarian cancer. In Phase I, ACCC evaluated the needs of cancer programs, conducted 3 quality improvement (QI) workshops, and developed expert-driven Quality of Care recommendations to aid cancer programs in self-assessment and quality improvement. In Phase II, ACCC invited programs to self-assess their level of care using the Quality of Care recommendations. Methods: In 2022, ACCC surveyed 7 ovarian cancer programs across the US. Developed by a multidisciplinary expert steering committee, the 26-question survey assessed the patient populations served, services provided, diagnostic evaluations performed, access to molecular testing, and a self-assessment of quality care delivery and interest in conducting QI projects related to self-identified needs. The survey was administered in Qualtrics and summarized using descriptive statistics. Results: Surveys were completed by 1 community, 2 comprehensive community, 2 hospital-associated, 1 academic comprehensive, and 1 NCI-designated comprehensive cancer programs. The median annual ovarian cases was 40 [range: 2 to 68]. The 7 programs serve diverse racial/ethnic distribution of patients with ovarian cancer ranging from 55% Black to 60% Asian and 30% Pacific Islander. Five programs have a multidisciplinary team for ovarian cancer. All 5 multidisciplinary teams included gynecologic oncology and pathology; 3 teams also included medical oncology and or radiology colleague(s). Sites assessed their level of care for 7 domains of quality care from 1 (lowest) to 5 (highest). The average score was 4.0 for Care Coordination and Patient Education, Treatment Planning, and Disease Surveillance. Diagnosis and Initial Management scored on average 3.8, Equity in Care 3.25, Prevention and Screening 3.25, and Quality of Life 3.2. Sites ranked areas of interest for future QI projects (1 = area of most interest, 7 = area of least interest). The highest ranked domains were Care Coordination and Patient Education as well as Diagnosis and Initial management (average rankings 2.8). These were followed by Quality of Life (average 3.0), Prevention and Screening (Average 3.8), Treatment Planning (Average 4.4), Equity in Care (Average 5.0), and Disease Surveillance (Average 6.2). Conclusions: This assessment will be used to identify 4 additional sites for Phase II QI workshops. Findings from these projects will be combined, summarized, and disseminated to inform future education opportunities and QI initiatives. This initiative aims to help organize and standardize the care of patients with ovarian cancer and improve patient care coordination.

Senescent cells can drive age-related tissue dysfunction partially via a senescence-associated secretory phenotype (SASP) involving proinflammatory and profibrotic factors. Cellular senescence has been associated with a structural and functional decline during normal lung aging and age-related diseases such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). Asthma in the elderly (AIE) represents a major healthcare burden. AIE is associated with bronchial airway hyperresponsiveness and remodeling, which involves increased cell proliferation and higher rates of fibrosis, and resistant to standard therapy. Airway smooth muscle (ASM) cells play a major role in asthma such as remodeling via modulation of inflammation and the extracellular matrix (ECM) environment. Whether senescent ASM cells accumulate in AIE and contribute to airway structural or functional changes is unknown. Lung tissues from elderly persons with asthma showed greater airway fibrosis compared with age-matched elderly persons with nonasthma and young age controls. Lung tissue or isolated ASM cells from elderly persons with asthma showed increased expression of multiple senescent markers including phospho-p53, p21, telomere-associated foci (TAF), as well as multiple SASP components. Senescence and SASP components were also increased with aging per se. These data highlight the presence of cellular senescence in AIE that may contribute to airway remodeling.
