Abstract BACKGROUND Access to in-person evaluations is challenging for patients with glioma due to disease-related disability and distance from specialized neuro-oncology centers. Telehealth is an alternative to in-person evaluations, but acceptability of and therapy compliance with this model has not been prospectively evaluated. METHODS In this single-arm non-randomized pragmatic clinical trial, we compared patient satisfaction with telehealth and in-person assessments among patients with glioma undergoing chemotherapy with temozolomide. Participants acted as their own controls, alternating between telehealth and in-person visits. Patient satisfaction with care delivered was evaluated by Press-Ganey surveys with Likert response scales (1-5, 1=very poor, 5=very good). A digital pill diary (DPD) was implemented to track chemotherapy compliance. RESULTS We accrued 30 patients (median age 59, 38% female) between October 2024 and May 2025. Half of the patients (n=15) reported a primary residence greater than 150 miles from our institution. Surveys from 25 participants were reviewed, with 17/25 completing one or more surveys following an in-person visit, and 21/25 completing one or more surveys following a telehealth visit. Overall average Press-Ganey scores were similar between the two visit modalities with high scores (telehealth=4.8; in-person=4.7). Median scores for specific modalities were similarly highly rated: likelihood of recommending practice to others (telehealth=5.0; in-person=5.0), concern the care provider showed (telehealth=5.0, in-person=4.7), provider’s discussion of treatment options (telehealth=5.0, in-person=5.0), provider effort to include patients in decision-making (telehealth=5.0, in-person=5.0). DPDs used to monitor treatment compliance indicated adherence to all prescribed doses of temozolomide in 75/79 cycles; the other 4 (of 79) treatment cycles were halted per provider instructions. CONCLUSION This interim assessment demonstrates feasibility of treating patients with similar patient satisfaction of care delivered between telehealth and in-person visits. The DPD was effective in tracking chemotherapy administration. Additional results including visit type preference and acute care utilization data are maturing.

Abstract BACKGROUND The majority of pituitary neuroendocrine tumors (PitNETs) are effectively managed with medical therapy, surgery, and/or radiation therapy; however, a subset of pituitary adenomas exhibit aggressive behavior. Temozolomide is thought to be an effective treatment option for patients with PitNETs. METHODS We identified and retrospectively reviewed 11 patients with pituitary tumors treated with temozolomide. We then conducted a review of the literature, combining 114 previously published cases with our cohort. RESULTS 125 cases were identified with diagnoses of pituitary adenomas (n=45), aggressive pituitary tumors (n=61), and pituitary carcinoma (n=19) treated with temozolomide. 79 patients were male (68.1%) with a median age of 47.5 (range 9-72). A variety of tumor types were represented: 50 corticotroph adenomas (40.7%), 37 prolactinomas (30.1%), 22 hormone nonfunctioning adenomas (17.9%), 8 somatotroph adenomas (6.5%), 6 other functioning adenomas (4.9%), and 2 cases where the functional status was not mentioned. Median treatment duration was 9 cycles (n=91, 150-200 mg/m2 days 1-5, 28-day cycles; n=2, 75 mg/m2, days 1-21, 28-day cycles; n=1, 75 mg/m2 daily). 27 patients received concurrent therapy with a dopamine agonist/somatostatin analogue (n=10), other chemotherapy agent (n=9) or radiotherapy (n=8). Radiographic responses included stable disease (n=40), partial response (n=35), complete response (n=8), and progressive disease (n=30). Hormonal responses included complete response (n=13), partial response (n=32), and no response (n=16). 22 patients (47.8%; out of 46 patients where progression/recurrence was assessed) experienced progression/recurrence following temozolomide initiation with a median progression free survival (PFS) of 24 months. There was no significant association between MGMT methylation status and radiological or hormonal response. No unexpected toxicities were observed. CONCLUSION In this cohort, temozolomide was well-tolerated with a median PFS of 24 months. MGMT methylation status did not predict temozolomide response. Temozolomide is an option with a survival benefit for patients with PitNETs.

Importance Treatment for cognitive dysfunction due to postacute sequelae of long COVID (ie, symptoms of fatigue, malaise, weakness, confusion that persist beyond 12 weeks after an initial COVID infection) remains a significant unmet need. Objective To test evidence-based rehabilitation strategies for improving cognitive symptoms in persons with long COVID. Design, Setting, and Participants This was a 5-arm, multicenter, randomized clinical trial of 3 remotely delivered interventions conducted between August 17, 2023, and June 10, 2024. The study took place at 22 trial sites and included the screening of individuals with cognitive long COVID. Interventions Participants were randomized to 1 of 5 arms: adaptive computerized cognitive training (BrainHQ [Posit Science]), cognitive-behavioral rehabilitation involving both group and individual counseling sessions (PASC-Cognitive Recovery [PASC-CoRE]) paired with BrainHQ, and transcranial direct current stimulation (tDCS) paired with BrainHQ. Two comparator arms were included as follows: unstructured computer puzzles and games (active comparator) and sham tDCS paired with BrainHQ. The interventions occurred 5 times per week over 10 weeks. Main Outcomes and Measures Cognitive and behavioral in-person assessments were performed at baseline, midintervention, at the end of intervention, and 3 months after the end of the intervention. The primary outcome measure was the modified Everyday Cognition Scale 2 (ECog2) completed at the end of the intervention compared to the baseline visit based on participant self-report looking back over the prior 7 days. Results A total of 378 individuals were screened, from which there were 328 participants (median [IQR] age, 48.0 [37.0-58.0] years; 241 female [73.5%]; race: 15 Asian [4.6%], 47 Black [14.3%], and 235 White [71.6%]; ethnicity: 52 Hispanic [15.9%]). None of the 3 active interventions demonstrated benefits on the modified ECog2 in the intention-to-treat population by the end of the intervention period. The adjusted differences in mean change were 0.0 (95% CI, −0.2 to 0.2) for BrainHQ vs active comparator, 0.1 (95% CI, −0.1 to 0.3) for PASC-CoRE + BrainHQ vs active comparator, 0.0 (95% CI, −0.2 to 0.2) for tDCS-active + BrainHQ vs tDCS-sham + BrainHQ, and 0.1 (95% CI, −0.1 to 0.3) for PASC-CoRE + BrainHQ vs BrainHQ alone. Secondary participant-reported outcomes and neuropsychological tests showed no differential benefits for any treatment arm. All 5 arms demonstrated some improvements over time on the modified ECog2 and on secondary outcomes. There were no serious adverse events attributable to the interventions. Conclusions and Relevance This phase 2 randomized clinical trial failed to demonstrate differential benefits for online cognitive training, a structured cognitive rehabilitation program, and tDCS for cognitive long COVID.

Abstract INTRODUCTION The Consortium for Clarity in Alzheimer's disease related dementias (ADRD) Research Through Imaging (CLARiTI) is a study that aims to collect standardized imaging and plasma biomarkers on 2000 Clinical Core participants enrolled across all Alzheimer's Disease Research Centers (ADRC) sites. We sought to summarize the known heterogeneity across centers regarding scientific focus and initial enrollment plans for CLARiTI. METHODS We developed and distributed a survey capturing information on the 36 CLARiTI site's theme/expertise, recruitment plans, and the intersection of CLARiTI with other ADRC imaging efforts. RESULTS Anticipated CLARiTI enrollees spanned 11 different categories of suspected etiologies underlying impairment. A wide range of risk factors were endorsed across sites regarding the enrollment of unimpaired individuals. Variability also existed regarding site‐level strategies in enrollment into CLARiTI versus other imaging efforts. DISCUSSION We anticipate that the 2000 individuals that will enroll into CLARiTI will reflect the clinical heterogeneity already in place across the ADRC network. Highlights The ADRC Consortium for Clarity in ADRD Research Through Imaging (CLARiTI) will leverage and contribute to the existing Alzheimer's Disease Research Centers (ADRC) program by supporting standardized imaging and plasma collection across all centers. We summarize the variation in scientific focus and enrollment plans across ADRC sites participating in CLARiTI. The anticipated CLARiTI cohort will reflect the clinical heterogeneity that already exists across the ADRC network. CLARiTI will contribute to scientific goals related to the detection of multi‐etiological signatures relevant for Alzheimer's disease and related disorders (ADRDs).

Background: Fecal microbiota, live-jslm (RBL) is a microbiota-based product for the prevention of recurrent Clostridioides difficile infection (rCDI) in adults following antibiotic treatment. The safety and clinical effectiveness of RBL administered via colonoscopy in adults with rCDI were evaluated in CDI-SCOPE. An 8-week analysis showed 9.8% of participants had RBL-related treatment-emergent adverse events (TEAEs; primary endpoint) and 95.1% experienced treatment success (no CDI recurrence). Objectives: To evaluate long-term safety and clinical effectiveness of RBL through 6 months of follow-up in CDI-SCOPE. Design: Single-arm exploratory phase IIIb trial conducted at 12 sites in the United States. Methods: Eligible adults with rCDI received a single 150-mL dose of RBL to the right colon via colonoscopy. The primary endpoint was RBL-related TEAEs through 8 weeks after RBL administration or confirmed treatment failure. Secondary endpoints included safety up to 6 months after RBL administration. Exploratory analyses included assessment of further CDI episodes. Results: Of the 41 participants enrolled, 39 completed trial assessments through 6 months. From 8 weeks through 6 months after RBL administration, 36 TEAEs in 15 participants (36.6%) were reported, one of which (irritable bowel syndrome) was RBL-related; most TEAEs (97.2%) were of mild or moderate severity. Over the 6-month trial period, 23 participants (56.1%) experienced 69 TEAEs; 94.2% were of mild or moderate severity. Serious TEAEs occurred in three participants (7.3%), none of which were related to RBL or its administration, and no TEAEs led to discontinuation or death. Overall, 38 participants (92.7%) did not experience further CDI episodes, 1 (2.4%) did between 8 weeks and 6 months, and 2 (4.9%) had an indeterminate outcome due to trial withdrawal before 8 weeks. Conclusion: RBL administered via colonoscopy was safe and effective for preventing CDI recurrence in adults with rCDI in CDI-SCOPE. Trial registration: ClinicalTrials.gov: NCT05831189.

Abstract Background and Aims Patients with catecholaminergic polymorphic ventricular tachycardia (CPVT) are at risk for potentially life-threatening arrhythmic events (AEs) even while treated with β-blockers. The aim was to develop a model for individualized prediction of AEs in patients with RYR2-mediated CPVT on β-blocker monotherapy. Methods The derivation and independent validation cohorts included 743 and 129 patients, respectively. AEs were defined as arrhythmic syncope, appropriate implantable cardioverter–defibrillator shock, sudden cardiac arrest (SCA), and sudden cardiac death. Near-fatal or fatal AEs (nf/fAEs) included all AEs except for arrhythmic syncope. Prediction models using Cox regression were developed and internally and externally validated. Results A total of 102 (13.7%) patients in the derivation cohort and 24 (18.6%) patients in the validation cohort experienced ≥1 AE over a median follow-up of 5.1 [interquartile range (IQR), 7.7] and 2.4 (IQR, 4.4) years, respectively. Predictors of AE were arrhythmic syncope or SCA prior to diagnosis and age at β-blocker initiation. In the derivation and validation cohorts, the optimism-corrected C-indices of the models for AE were 0.67 [95% confidence interval (CI) 0.62–0.72] and 0.59 (95% CI 0.48–0.71), respectively. For nf/fAEs, ventricular arrhythmia severity before β-blocker initiation was a fourth independent predictor, and C-indices of the models in the derivation and validation cohorts were 0.74 (95% CI 0.68–0.80) and 0.60 (95% CI 0.47–0.72), respectively. In the derivation cohort, calibration slopes were 1.00 (95% CI 0.59–1.41) for AE and 1.00 (95% CI 0.69–1.32) for nf/fAE. Conclusions These externally validated risk prediction models using clinical parameters accurately distinguished CPVT patients on β-blocker monotherapy at low and high risk for future AEs while treated with β-blockers. These models provide guidance for implementation of clinical management therapies to prevent AEs in patients with CPVT.

Abstract Background Obesity is strongly associated with the development of heart failure (HF) with preserved ejection fraction (HFpEF). Beyond increased body mass index (BMI), an abundance of epicardial adipose tissue (EAT) may play a role in its pathophysiology. Purpose To study the associations between increased EAT, functional status and invasive exercise hemodynamics in a large cohort of HFpEF patients. Methods This is a sub-analysis from a large randomized clinical trial that investigated an atrial shunt device in patients with HF with left ventricular ejection fraction ≥40% and exercise pulmonary capillary wedge pressure (PCWP) ≥25mmHg. At baseline, all patients underwent echocardiography, 6-minute walk distance (6-MWD) test, Kansas City Cardiomyopathy Questionnaire (KCCQ) and invasive hemodynamic assessment at rest and during supine ergometry. EAT thickness was measured on the free wall of the right ventricle on echocardiography, expressed in mm and patients were divided according to EAT tertiles. Results In total, 566 patients were examined. Their mean age was 72±8 years, 62% were women, mean BMI was 33±6 kg/m2 and mean EAT thickness was 6.0±2.4 mm, ranging from 1.7 to 17.2 mm. With increasing EAT thickness tertiles, 6-MWD and KCCQ overall summary score were significantly lower (320 vs. 315 vs. 287m, p=.01; 51 vs. 45 vs. 41, p=.003; respectively, Figure 1A-B). The association between increased EAT and lower KCCQ score was independent of BMI (p=.004, β: -2.6), whereas the association with lower 6-MWD was not independent of BMI (p=.1, β: -6.9). At rest, invasive hemodynamics were not different across EAT tertiles. At peak exercise, patients in the highest EAT thickness tertile had higher PCWP and PCWP to right atrial pressure gradient, as compared to patients in the first and second EAT thickness tertiles (36±8 vs. 34±8 mmHg, p=.009; 18±7 vs. 16±7 mmHg, p=.002, respectively, Figure 1C). Conclusion Excess EAT is common in patients with HFpEF and is associated with lower functional status and with higher left-sided filling pressures at peak exercise. These data suggest that EAT plays a significant role in functional status and exercise hemodynamics in HFpEF.Figure 1

Abstract Background We examined real-world utilization of treat-to-target (TTT) strategies and conducted a quality improvement (QI) project to improve uptake of TTT strategies in a learning health system, IBD Qorus. Methods We implemented a structured QI intervention to increase uptake of TTT in 41 gastroenterology practices in the United States, over a 13-month intervention period (November 2020 to November 2021; modified breakthrough series [BTS] collaborative), and a 10-month post-BTS observation period (December 2021 to October 2022). Through encounter-level surveys, we examined providers’ “intention to TTT” based on discussion of TTT with patients, documentation of inflammation, and intention to change therapy to TTT. We examined changes in rates of “intention to TTT,” and whether improvement in intention to TTT influenced site-level rates of remission. Results Over 13 months, there were 7932 patient visits (55% with Crohn’s disease; 47% in clinical remission); patients in 2160 visits (27%) were not in endoscopic remission. Overall, rates of intention to TTT increased from 31% to 54% (P = .06) with considerable site-to-site variability and was maintained at 49% in the post-BTS observation period. The increased rate was attributable to higher rates of testing for inflammation. Despite an increase in the rate of intention to TTT, there was no significant change in site-level achievement of remission over the same time. Conclusions Through a QI initiative in a learning health system, rates of intention to TTT increased significantly over 12-months, though overall rates remained low. Assessing patient-, provider- and practice-level barriers and facilitators for successful implementation of a TTT strategy is warranted to improve clinical outcomes.

Abstract Background The associations between different types of diabetes, characterized by distinct pathophysiology and genetic architecture, and pancreatic ductal adenocarcinoma (PDAC) risk are not understood. Methods We investigated associations of genetic susceptibility to type 2 diabetes (T2D), 8 T2D mechanistic clusters, type 1 diabetes (T1D), and maturity-onset diabetes of the young (MODY) with PDAC risk. We used genome-wide association study (GWAS) summary-level statistics for T2D (242 283 cases, 1 569 734 controls), T1D (18 942 cases, 501 638 controls), and PDAC (10 244 cases and 360 535 controls) in individuals of European ancestry. Results Two-sample Mendelian randomization (MR) using the Robust Adjusted Profile Score (MR-RAPS) method indicated that genetically predicted T2D was associated with PDAC risk (OR = 1.10; 95% CI = 1.05 to 1.15), particularly the T2D obesity (OR = 1.28; 95% CI = 1.15 to 1.42) and lipodystrophy (OR = 1.25; 95% CI = 1.03 to 1.51) clusters. No association was observed for T1D with PDAC risk (OR = 1.01; 95% CI = 0.99 to 1.02). Pathway/gene-set analysis using the summary-based Adaptive Rank Truncated Product (sARTP) method revealed a significant association between the MODY gene-sets and PDAC risk (P = 1.5 × 10−8), which remained after excluding 20 known PDAC GWAS loci (P = 7.6 × 10−4). HNF1A, FOXA3, and HNF4A were the top contributing genes after excluding the previously identified GWAS loci regions. Conclusions Our results from this genetic association study support that T2D, particularly the obesity and lipodystrophy mechanistic clusters, and MODY genomic susceptibility regions play a role in the etiology of PDAC.

OBJECTIVE While endonasal transsphenoidal surgery (ETS) is the standard treatment for nonfunctioning pituitary adenomas (NFPAs), the postoperative recovery rates of secondary adrenal insufficiency and their predictive factors remain poorly understood. The authors investigated the relationship between the tumor resection rate and adrenal function recovery in patients with NFPAs. METHODS This retrospective study included 450 patients with NFPAs who underwent ETS between January 2013 and November 2023. The rates of preoperative hypopituitarism and postoperative recovery rates of secondary adrenal insufficiency and their associated factors were analyzed. Recovery was defined as normalization of serum cortisol levels without replacement therapy for at least 24 hours, accompanied by symptom resolution. The tumor resection rate was calculated as the percentage of the tumor volume resected. RESULTS The median follow-up period for the entire cohort was 52 months (range 1–131 months). A total of 246 (55%) patients had dysfunction in one or more pituitary axes. Fifty-three (47%) of 114 patients with preoperative adrenal insufficiency showed postoperative adrenal insufficiency recovery. The cumulative adrenal insufficiency recovery rates were 12% at 1 month, 19% at 3 months, 32% at 6 months, and 41% at 12 months. Among the 114 patients with preoperative adrenal insufficiency, the factors associated with postoperative adrenal insufficiency recovery were investigated. Patients with smaller tumor sizes of < 20 mm (log-rank test, p = 0.001) and those with tumor resection rates of more than 85% (log-rank test, p = 0.032) demonstrated better postoperative adrenal insufficiency improvement. Bivariate Cox proportional hazards analysis demonstrated that smaller tumor sizes (continuous, HR 0.97, 95% CI 0.93–0.98; p = 0.043) and higher tumor resection rates (HR 1.03, 95% CI 1.01–1.07; p = 0.001) were significantly associated with better postoperative adrenal insufficiency recovery. Multivariable analysis confirmed that only higher tumor resection rates were significantly associated with better postoperative adrenal insufficiency recovery (HR 1.03, 95% CI 1.01–1.06; p = 0.019). CONCLUSIONS Nearly half of the patients with preoperative adrenal insufficiency achieved recovery after ETS for NFPAs. The enhanced extent of tumor removal was an independent factor associated with better postoperative recovery, indicating that optimizing safe maximal resection procedures may be crucial in enhancing adrenal function.
