Purpose: Functional septorhinoplasty is an effective treatment for nasal airway obstruction. Little distinction exists between bilaterally and unilaterally obstructed patients in literature. Our study evaluates outcomes in patients with unilateral nasal airway obstruction compared to those with bilateral nasal airway obstruction as measured by nasal obstruction symptom evaluation scores following functional septorhinoplasty. Materials and Methods: A total of 227 patients underwent functional septorhinoplasty for nasal airway obstruction. Patients were grouped into unilateral (n = 64) and bilateral (n = 163) nasal obstruction cohorts based on patient report and physician assessment. Nasal obstruction symptom evaluation (NOSE) scores were obtained pre-operatively and post-operatively at least 3 months following surgery. Results: Patients with unilateral nasal obstruction had slightly less severe symptoms preoperatively than patients with bilateral obstruction. Average preoperative NOSE scores for patients with unilateral obstruction was 64 (SD = 19) and 72 (SD = 18) for patients with bilateral obstruction ( P = .004). Postoperative NOSE scores following septorhinoplasty were significantly reduced for patients with both unilateral and bilateral nasal obstruction (postoperative NOSE scores unilateral: 17, SD = 16 ; bilateral: 23, SD = 21). There was no statistical significance in outcomes between patients with unilateral or bilateral nasal obstruction groups. Conclusions: Symptoms in patients with unilateral obstruction are similar but slightly less severe than patients with bilateral obstruction. Patients with unilateral and bilateral nasal obstruction experienced a similar degree of improvement in symptom following functional septorhinoplasty.

Abstract GBM AGILE(NCT03970447) is a phase 2/3 Bayesian adaptive registration platform trial testing multiple therapies against a common control. Paxalisib, a PI3K/mTOR inhibitor, is the 3rd arm in the trial to conclude evaluation. METHODS Paxalisib was open to patients with newly diagnosed unmethylated (NDU) and recurrent (RD) glioblastoma, with three possible signatures: NDU, RD, and All(NDU+RD). Arm enrollment occurred Dec2020 through May2022. Control patients were enrolled from study initiation (July2019) and were treated with temozolomide(NDU) or lomustine(RD). GBM AGILE investigational arms have 1 or 2 stages, with adaptive randomization in stage 1 and fixed randomization if arms continue to stage 2. Efficacy is based on OS hazard ratio(HR) of Arm/Control. Efficacy goal is final Bayesian probability ≥ 98% for HR<1.00 in combined Stages. An Arm continues to Stage 2 if Bayesian predictive power (PP) ≥ 0.8. An Arm stops accruing in Stage 1 if it reaches maximal sample size(N) or does not meet a minimum efficacy threshold (PP<0.25 for all signatures when N>50). Clinical cut-off is 12 months after accrual stops. The maximum N for paxalisib was approximately 150(Stage 1) and 50(Stage 2). RESULTS After paxalisib reached >150 patients in Stage 1, accrual stopped [Paxalisib/control N 54/75(NDU), 100/188(RD)]. Neither PP thresholds for moving to Stage 2 nor stopping for minimum efficacy were met. Following an unplanned public disclosure that the arm did not continue to stage 2, clinical cut-off for final analysis (planned May2023) was updated to public disclosure date (August2022). At final analysis mean HRs were 0.89(NDU), 1.25(RD), 1.05(All), probabilities of HR<1.00 of 0.72(NDU), 0.076(RD), 0.398(All). Model estimated median OS paxalisib/control (months) were 14.77/13.84(NDU) and 8.58/10.06(RD). CONCLUSION Paxalisib did not show survival benefit over cumulative control in final primary analysis; additional secondary analyses are being considered. GBM AGILE continues to rapidly and efficiently assess therapies in ND and RD glioblastoma.

Background: Guidelines recommend shared decision-making (SDM) for patients with atrial fibrillation (AF) making decisions regarding anticoagulation for stroke prevention. Decision support tools (e.g., Decision Aids [DAs]) facilitate SDM. However, little research has compared the effectiveness of the two most common types of DAs: (1) encounter decision aid (EDA) and (2) pre-encounter patient decision aid (PDA). Our study assessed the comparative effectiveness of PDAs and EDAs on SDM during AF clinical encounters where stroke prevention strategies were discussed. Research Question: Do decision aids (PDA or EDA), alone or in combination, improve patients’ AF decision-making experience compared to usual care? Methods: A cluster randomized multi-center trial in patients with AF comparing usual care (no DA) vs. one DA (EDA or PDA) or both DAs. Clinicians and patients were randomized independently into 4 study arms. Clinicians were randomized to use or not use the EDA for all study visits, and patients were randomized to use or not use the PDA. Co-primary outcome domains were: (1) quality of SDM (2) patient knowledge, and (3) decisional conflict. Secondary outcomes included: (1) treatment choice, (2) treatment initiation, and (3) treatment persistence. Patient characteristics were assessed. We will present comparisons of the randomized DAs on the co-primary and secondary outcomes and subgroup analyses. Results: Between December 2020-July 2023, investigators in 6 U.S. healthcare systems enrolled 1117 patients (mean (M) age 69, 63% male, 89% White) and 107 clinicians. Compared to usual care (no DA, M=31.6), SDM was better in patients receiving PDA (M=35.4) and EDA (44.5) alone or together (M=43.7; p’s<0.001). Knowledge about AF was greatest for those receiving both DAs or the PDA alone (84% accurate responses for PDA and both vs 76% with no DA, p<0.001), followed closely by the EDA alone (82%, p=0.003). Finally, both DAs (M=19.5) and EDA alone (M=20.0) had better decisional conflict scores compared to usual care (M=25.8; p’s<0.001). We will present analyses that assess the impact of DAs on secondary outcomes and interactions with DA, patient, and clinical characteristics across each outcome. Conclusions: In one of the first randomized trials examining the comparative effectiveness of EDAs and PDAs on SDM in clinical medicine, both PDAs and EDAs improved shared decision-making, decisional conflict, and knowledge compared to patients receiving usual care.

Abstract Many patients in the emergency department present with signs and symptoms that arouse concern for sepsis; however, other explanations are also possible. There are currently no rapid tests used in clinical practice that reliably distinguish the presence of a bacterial or viral infection vs. a non-infectious etiology and can predict a patient’s likelihood to decompensate. The diagnostic and prognostic uncertainty in “gray zone” patients complicates the decision to begin therapy as clinicians need to balance the risk of withholding therapy vs. the risk of the therapy itself (e.g., overtreatment with antibiotics and hospitalization, which is costly, potentially harmful, and contributes to antibiotic resistance). The TriVerity™ Test uses isothermal amplification and machine-learning algorithms to quantify and interpret mRNA expression levels to determine both likelihood of bacterial infection, viral infection, or no infection, and whether the patient will likely require one or more critical interventions within 7 days. The three scores each fall into one of five interpretation bands ranging from Very high to Very low. Testing takes approximately 30 minutes using the proprietary Myrna™ Instrument with an operator hands-on-time of under one minute. We enrolled 1,222 patients from 22 emergency departments (ED) to validate the performance of the TriVerity Test. Patients were treated as per local standard of care and were followed for 28 days. Bacterial and viral TriVerity results were validated against clinically adjudicated infection status; the illness severity TriVerity result was validated against the need for at least one critical interventions within 7 days. The bacterial TriVerity result had high AUROC for the diagnosis of bacterial infection (0.83; 80% CI 0.81–0.85) and divided bacterial infection likelihood scores into five interpretation bands with increasing likelihood ratios of infection ranging from Very low (LR- 0.08, 80% CI 0.06–0.11) to Very high (LR + 8.04, 80% CI 5.72–11.78). The AUROC for the bacterial TriVerity result was significantly higher compared to AUROCs for C-reactive protein, procalcitonin or white blood cell count. Similarly, the viral TriVerity score showed high AUROC for the diagnosis of viral infection (0.91; 80% CI 0.90–0.93) and likelihood ratios from Very low (LR- 0.09, 80% CI 0.05–0.14) to Very high (LR + 40.93; 80% CI 29.11–79.23). The TriVerity Illness Severity score showed a high AUROC for the prediction of illness severity (0.77; 80% CI 0.77–0.81) with scores divided into five interpretation bands with increasing likelihood ratios ranging from Very low (LR- 0.22; 80% CI 0.14–0.33) to Very high (LR + 11.33; 80% CI 7.31–17.00). TriVerity illness severity results allowed marked re-classification of the risk for “ICU-level care” as compared to clinical assessment (qSOFA scores) alone. In conclusion, TriVerity provides rapid, highly accurate and actionable results for the diagnosis and prognosis of patients with suspected acute infection and/or sepsis, supporting a major unmet medical need. TriVerity may improve personalized management of patients with suspected acute infections and suspected sepsis for improved overall healthcare outcomes.

INTRODUCTION: Early neoplastic progression of Barrett's esophagus (BE) is often treated with endoscopic therapy. Although effective, some patients are refractory to therapy or recur after apparent eradication of the BE. The goal of this study was to determine whether genomic alterations within the treated BE may be associated with persistent or recurrent disease. METHODS: We performed DNA sequencing on pre-treatment esophageal samples from 45 patients who were successfully treated by endoscopic therapy and did not recur as well as pre-treatment and post-treatment samples from 40 patients who had persistent neoplasia and 21 patients who had recurrent neoplasia. The genomic alterations were compared between groups. RESULTS: The genomic landscape was similar between all groups. Patients with persistent disease were more likely to have pre-treatment alterations involving the receptor tyrosine kinase pathway ( P = 0.01), amplifications of oncogenes ( P = 0.01), and deletions of tumor suppressor genes ( P = 0.02). These associations were no longer significant after adjusting for patient age and BE length. More than half of patients with persistent (52.5%) or recurrent (57.2%) disease showed pre-treatment and post-treatment samples that shared at least 50% of their driver mutations. DISCUSSION: Pre-treatment samples were genomically similar between those who responded to endoscopic therapy and those who had persistent or recurrent disease, suggesting there is not a strong genomic component to treatment response. Although it was expected to find shared driver mutations in pre-treatment and post-treatment samples in patients with persistent disease, the finding that an equal number of patients with recurrent disease also showed this relation suggests that many recurrences represent undetected minimal residual disease.

6574 Background: Pts with MF experience debilitating symptoms that negatively impact health-related quality of life (HRQOL), a burden compounded in those with anemia. Prior analysis of the phase 3 SIMPLIFY-1 (S1) and SIMPLIFY-2 (S2) trials found that achieving transfusion independence at wk 24 was associated with improved PROs, but the association of anemia severity by Hb level with PROs was inconclusive (Mesa, ASCO 2023, Poster 7066). This new post hoc analysis explored the impact of Hb improvement on PROs in pts with MF and anemia. Methods: The pooled treatment-agnostic analysis set included pts with anemia (baseline [BL] Hb <10 g/dL) from 3 phase 3 trials: S1 (JAK inhibitor [JAKi] naive; MMB vs ruxolitinib), S2 (JAKi experienced; MMB vs best available therapy), and MOMENTUM (JAKi experienced; MMB vs danazol). The EQ-5D-5L was administered, and health state index (UK value set) and visual analog scale (VAS) scores derived, in all 3 trials. Patient Global Impression of Change (PGIC) was administered in S1/S2. Hb improvement was defined as an increase of ≥1, ≥1.5, or ≥2 g/dL from BL at wk 24. Multivariate (MV) analyses included change in EQ-5D-5L scores from BL as the dependent variable, with wk 24 Hb improvement and key BL characteristics as independent variables. Results: Mean age of the anemic subpopulation (N=480) was 68.8 y; 62% were male, 81% were White, and 64% had primary MF.436 pts were evaluable for Hb improvement at wk 24; 298 and 297 were evaluable for EQ-5D-5L index and VAS scores, respectively. Mean improvements from BL in index and VAS scores were greater in pts who achieved Hb improvement at any threshold than in those who did not (Table). 241 pts were evaluable for Hb improvement at wk 24 in S1/S2; 215 were evaluable for PGIC. Hb improvement was associated with a higher percentage of pts with any symptom improvement and lower percentage with symptom worsening based on PGIC (Table). In MV analyses, Hb improvement at any threshold was significantly associated with positive change in EQ-5D-5L VAS scores at wk 24 (mean change estimates of 5.5 to 7.3); similar trends were observed in MV analyses for EQ-5D-5L index scores. Conclusions: In these trial populations, Hb improvement at wk 24 was associated with improved HRQOL and symptoms in pts with MF and anemia. These results highlight the value of treatments with anemia-related benefits in improving the pt experience in MF. Clinical trial information: NCT04173494 ; NCT02101268 ; NCT01969838 .

Background and Hypothesis Clozapine is an effective yet underutilized treatment for treatment‐resistant schizophrenia spectrum disorders. This study aimed to identify factors affecting clozapine prescribing patterns among patients with treatment‐resistant schizophrenia and schizoaffective disorder at an academic medical center. Study Design This retrospective combined cohort and case‐control study examined demographic, socioeconomic, medical and psychiatric characteristics to determine predictors of clozapine initiation. Eligible patients had a diagnosis of schizophrenia or schizoaffective disorder with at least two prior antipsychotic trials and were admitted to a University of Utah inpatient psychiatric facility (1/2014–3/2021). Patients who did and did not receive clozapine during the index hospitalization were compared in cohort and case‐control study arms. Study Results Twelve percent (59/477) of the cohort received clozapine during the index admission. Among the cohort ( n = 477), Black patients were twice as likely to receive clozapine than White and Hispanic patients (OR 2.18, 95% CI 1.20–3.97, p = 0.008). In the case‐control analysis, patients with a greater number of previous psychiatric admissions (OR 1.14, p = 0.079) and antipsychotic trials (OR 1.40, p = 0.038) had greater odds of receiving clozapine. Homelessness was identified as a predictor against clozapine use (OR 2.77, p = 0.014). Conclusions This is the first study to identify homelessness as a predictor against clozapine use, which raises important clinical and ethical considerations. Our findings also add to the literature on clozapine prescribing discrepancies among ethnic‐minority patients. Overall, clozapine remains underutilized as the gold‐standard treatment for treatment‐resistant schizophrenia‐spectrum disorders, reinforcing a need to improve evidence‐based prescribing.

AbstractIntroductionPrior consensus meetings have addressed the relationship between phosphodiesterase type 5 (PDE5) inhibition and cardiac health. Given significant accumulation of new data in the past decade, a fourth consensus conference on this topic was convened in Pasadena, California, on March 10 and 11, 2023.ObjectivesOur meeting aimed to update existing knowledge, assess current guidelines, and make recommendations for future research and practice in this area.MethodsAn expert panel reviewed existing research and clinical practice guidelines.ResultsKey findings and clinical recommendations are the following: First, erectile dysfunction (ED) is a risk marker and enhancer for cardiovascular (CV) disease. For men with ED and intermediate levels of CV risk, coronary artery calcium (CAC) computed tomography should be considered in addition to previous management algorithms. Second, sexual activity is generally safe for men with ED, although stress testing should still be considered for men with reduced exercise tolerance or ischemia. Third, the safety of PDE5 inhibitor use with concomitant medications was reviewed in depth, particularly concomitant use with nitrates or alpha-blockers. With rare exceptions, PDE5 inhibitors can be safely used in men being treated for hypertension, lower urinary tract symptoms and other common male disorders. Fourth, for men unresponsive to oral therapy or with absolute contraindications for PDE5 inhibitor administration, multiple treatment options can be selected. These were reviewed in depth with clinical recommendations. Fifth, evidence from retrospective studies points strongly toward cardioprotective effects of chronic PDE5-inhibitor use in men. Decreased rates of adverse cardiac outcomes in men taking PDE-5 inhibitors has been consistently reported from multiple studies. Sixth, recommendations were made regarding over-the-counter access and potential risks of dietary supplement adulteration. Seventh, although limited data exist in women, PDE5 inhibitors are generally safe and are being tested for use in multiple new indications.ConclusionStudies support the overall cardiovascular safety of the PDE5 inhibitors. New indications and applications were reviewed in depth.
