Abstract Background Upadacitinib (UPA) is an oral selective Janus kinase inhibitor approved for the management of moderate-to-severe Crohn’s disease (CD). One in ten CD patients may need a permanent ostomy (colostomy or ileostomy) during their disease course, and this may impact the efficacy of UPA, given its extended-release formulation. However, there is no data available in this population since patients with an ostomy are excluded from registrational CD trials. This study addresses this gap by comparing the real-world clinical effectiveness of UPA in CD patients with and without ostomy. Methods This retrospective cohort study analyzed data from the TriNetX US Collaborative Network of sixty-eight tertiary institutions, to examine adult (≥18 years) CD patients treated with UPA from May 19th, 2023 (FDA approval date) to October 31st, 2024. Patients were categorized based on presence or absence of an ostomy during the previous 5 years, after exclusion of patients with rheumatologic disease indications for UPA usage. A 1:1 propensity score matching (PSM) was performed to balance cohorts on demographics, baseline comorbidities, and CD severity indicators (CD phenotype, extraintestinal manifestations, concurrent corticosteroid and other biologics usage, hemoglobin, and body weight). Cox proportional hazards model estimated hazard ratios (HRs) in matched cohorts for clinical effectiveness as a composite outcome (corticosteroid use, hospitalizations, emergency room visits) and secondary individual outcomes, at one year post-treatment, with a significance threshold set at p < 0.05. Results The study sample of CD patients on UPA included 170 with and 1,428 without a prior ostomy. There were 144 patients in each cohort after PSM. Baseline characteristics of the cohorts are shown in Figure 1. After PSM (Figure 2), there were no significant differences between patients with CD on UPA, with and without prior ostomy, for composite outcomes (HR 0.93, p = 0.64), corticosteroid use (HR 0.78, p = 0.18), hospitalizations (HR 1.13, p = 0.64), or emergency room visits (HR 0.99, p = 0.97). Additionally, no significant differences were observed in opioid use (HR 0.95, p = 0.76), switch to another advanced therapy (HR 1.62, p = 0.06), or elevated biomarkers, including CRP (>10 mg/L, HR 1.00, p = 0.99) and fecal calprotectin (>150 µg/g, HR 0.85, p = 0.63) at the 1-year follow-up. Conclusion In CD patients, UPA demonstrated similar effectiveness for clinical outcomes of corticosteroid use, hospitalizations, emergency room visits and other secondary outcomes, regardless of their ostomy status.

Importance Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology. Objective To examine the association between depressive symptoms and amyloid pathology and its dependency on age, sex, education, and APOE genotype in older individuals without dementia. Design, Setting, and Participants Cross-sectional analyses were performed using data from the Amyloid Biomarker Study data pooling initiative. Data from 49 research, population-based, and memory clinic studies were pooled and harmonized. The Amyloid Biomarker Study has been collecting data since 2012 and data collection is ongoing. At the time of analysis, 95 centers were included in the Amyloid Biomarker Study. The study included 9746 individuals with normal cognition (NC) and 3023 participants with mild cognitive impairment (MCI) aged between 34 and 100 years for whom data on amyloid biomarkers, presence of depressive symptoms, and age were available. Data were analyzed from December 2022 to February 2024. Main Outcomes and Measures Amyloid-β1-42 levels in cerebrospinal fluid or amyloid positron emission tomography scans were used to determine presence or absence of amyloid pathology. Presence of depressive symptoms was determined on the basis of validated depression rating scale scores, evidence of a current clinical diagnosis of depression, or self-reported depressive symptoms. Results In individuals with NC (mean [SD] age, 68.6 [8.9] years; 5664 [58.2%] female; 3002 [34.0%] APOE ε4 carriers; 937 [9.6%] had depressive symptoms; 2648 [27.2%] had amyloid pathology), the presence of depressive symptoms was not associated with amyloid pathology (odds ratio [OR], 1.13; 95% CI, 0.90-1.40; P = .29). In individuals with MCI (mean [SD] age, 70.2 [8.7] years; 1481 [49.0%] female; 1046 [44.8%] APOE ε4 carriers; 824 [27.3%] had depressive symptoms; 1668 [55.8%] had amyloid pathology), the presence of depressive symptoms was associated with a lower likelihood of amyloid pathology (OR, 0.73; 95% CI 0.61-0.89; P = .001). When considering subgroup effects, in individuals with NC, the presence of depressive symptoms was associated with a higher frequency of amyloid pathology in APOE ε4 noncarriers (mean difference, 5.0%; 95% CI 1.0-9.0; P = .02) but not in APOE ε4 carriers. This was not the case in individuals with MCI. Conclusions and Relevance Depressive symptoms were not consistently associated with a higher frequency of amyloid pathology in participants with NC and were associated with a lower likelihood of amyloid pathology in participants with MCI. These findings were not influenced by age, sex, or education level. Mechanisms other than amyloid accumulation may commonly underlie depressive symptoms in late life.

Abstract Background Tumor necrosis factor-like ligand 1A (TL1A) is upregulated in inflammatory bowel disease and believed to promote inflammation and intestinal fibrosis. RO7790121, an anti-TL1A antibody, showed promising results in the phase IIa TUSCANY trial.1 Here we report post-hoc analyses of patient-reported outcomes from the TUSCANY-2 trial. Methods This phase IIb, multicenter, randomized, double-blind, treat-through, dose-ranging study evaluated RO7790121 in patients (pts) aged 18–75 years with moderately to severely active ulcerative colitis (UC) (total Mayo score [MS] ≥6, endoscopic subscore ≥2). Pts were randomized to receive subcutaneous (SC) RO7790121 50mg, 150mg, 450mg or matched placebo (PBO) monthly during the 12-week induction period, and SC RO7790121 50mg, 150mg or 450mg monthly during the 40-week treat-through maintenance period. To assess efficacy of RO7790121 in supporting pts achieving early symptomatic improvement, rectal bleeding (RB), stool frequency (SF) and partial modified MS (RB+SF) were evaluated at baseline and Weeks 2, 4, 8, 12 and 14. The exploratory endpoint of symptomatic remission, defined as a RB subscore of 0 and a SF subscore of 0 or 1, was assessed throughout induction. Safety was assessed throughout the study. Results Overall, 245 pts received ≥1 dose of RO7790121 or PBO. At Week 2, pts receiving RO7790121 were more likely to report a RB subscore of 0 (34% RO7790121; 20% PBO) and less likely to report a RB subscore of 2 or 3 (25% RO7790121; 40% PBO) (Figure). Improvements in SF increased from Week 2 and throughout induction, with ~60% of pts receiving RO7790121 reporting a SF subscore of 0 or 1 at Weeks 12 and 14, vs ~40% for PBO. Greater rates of symptomatic remission were observed in pts receiving RO7790121 vs PBO throughout induction and from Week 2 (17.5% RO7790121; 8.9% PBO) (Table). Treatment-emergent adverse events (TEAEs) were reported during induction in 117/245 pts, the most common (reported in ≥5% of pts in any treatment group) were nausea, urinary tract infection and UC (highest in the 50mg arm), anemia (highest in the placebo arm) and fatigue, headache and pyrexia (highest in the 450mg arm). Serious TEAEs were reported in ten pts during induction (PBO=4; 50mg=3; 450mg=3); two were treatment related (PBO=1; 450mg=1). There were six treatment discontinuations due to TEAEs and a generally similar safety profile was observed during the maintenance period. Conclusion Greater and earlier improvements in RB and SF were observed in pts receiving RO7790121 vs PBO. These results indicate early symptom relief and a favorable safety profile for pts treated with RO7790121, supporting its further clinical development.

PURPOSE In patients with relapsed or refractory (R/R) diffuse large B-cell lymphoma (DLBCL), brentuximab vedotin (BV) as monotherapy or combined with either lenalidomide (Len) or rituximab (R) has demonstrated efficacy with acceptable safety. We evaluated the efficacy and safety of BV + Len + R versus placebo + Len + R in patients with R/R DLBCL. METHODS ECHELON-3 is a randomized, double-blind, placebo-controlled, multicenter, phase 3 trial comparing BV + Len + R with placebo + Len + R in patients with R/R DLBCL. Patients received BV or placebo once every 3 weeks, Len once daily, and R once every 3 weeks. The primary end point was overall survival (OS), and secondary end points included investigator-assessed progression-free survival (PFS) and objective response rate (ORR). A prespecified interim analysis was performed after 134 OS events, with two-sided P = .0232 as the efficacy boundary. RESULTS Patients (N = 230) were randomly assigned to receive BV + Len + R (n = 112) or placebo + Len + R (n = 118). Two patients in the placebo arm did not receive treatment. With a median follow-up of 16.4 months, the median OS was 13.8 months with BV + Len + R versus 8.5 months with placebo + Len + R (hazard ratio, 0.63 [95% CI, 0.45 to 0.89]; two-sided P = .009). The median PFS was 4.2 months with BV + Len + R versus 2.6 months with placebo + Len + R (hazard ratio, 0.53 [95% CI, 0.38 to 0.73]; two-sided P < .001). The ORR was 64% ([95% CI, 55 to 73]; two-sided P < .001) with BV + Len + R and 42% (95% CI, 33 to 51) with placebo + Len + R; complete response rates were 40% and 19%, respectively. Treatment-emergent adverse events (AEs) occurred in 97% of patients in both arms. In both arms, the most common treatment-emergent AEs were neutropenia, thrombocytopenia, diarrhea, and anemia. CONCLUSION BV + Len + R demonstrated a statistically significant survival benefit with a manageable safety profile in heavily pretreated patients with R/R DLBCL.

AbstractBackgroundPrior longitudinal studies among older adults have documented associations between hearing loss and changes in brain morphology. Whether interventions involving hearing aids can reduce age‐related atrophy is unknown. A substudy within the Aging and Cognitive Health Evaluation in Elders (ACHIEVE, Clinicaltrials.gov Identifier: NCT03243422) randomized controlled trial tested the effect of a best‐practices hearing intervention versus health education control on three‐year change in cortical thickness among older adults with hearing loss.MethodThe ACHIEVE study enrolled 977 community‐dwelling adults aged 70‐84 years at baseline (2018‐2019) with untreated hearing loss (better ear pure tone average [0.5‐4 kHz] ≥30 and <70 dB HL) and without substantial cognitive impairment from four sites across the U.S. (Jackson, MS, Forsyth County, NC, Minneapolis, MN, Washington County, MD). Participants were randomized to a hearing intervention (provision of hearing aids and related technologies, counseling, and education) or a health education control (individual sessions with a health educator covering topics relevant to chronic disease and disability prevention). Three‐dimensional magnetic resonance imaging was performed on 3 Tesla Siemens scanners in a subsample of 445 participants at the ACHIEVE baseline and three‐year follow‐up. Linear mixed effects models were used in intention‐to‐treat analyses to estimate three‐year change in cortical thickness. All models adjusted for baseline measures of hearing loss, recruitment source, site, age, sex, and education. Missing outcome and covariate data was imputed to mitigate bias caused by informative attrition.ResultAt baseline, 224 participants were women (50.3%), 52 participants were Black (11.7%), and the mean (SD) age was 76.4 (4.0) years old (Table 1). Compared to the health education control, the hearing intervention exhibited a nominally protective effect on three‐year change in average cortical thickness (Figure 1). The greatest effect size for cortical thickness was observed in the occipital lobe, while the smallest effect size was detected in the temporal lobe. Statistically significant effects were detected in the pars orbitalis, rostral anterior cingulate, posterior cingulate, and isthmus cingulate (Figure 2).ConclusionHearing aid use may reduce decline in cortical thickness among older adults. The effects of hearing aids may be greatest in regions other than those associated with the auditory cortex.

This review article represents a collaborative effort across continents, bringing together the latest developments in neuro-ophthalmology with a focus on innovative diagnostic and therapeutic modalities that are shaping the future of the field. Among the most significant advancements is the rise of optical coherence tomography (OCT), now recognized as an indispensable tool in neuro-ophthalmological research, providing unparalleled insights into optic nerve and central nervous system pathologies. Gene therapy, particularly for conditions such as Leber's hereditary optic neuropathy, marks a new frontier in personalized medicine, offering hope for previously untreatable conditions. The article also examines the transformative role of telemedicine and artificial intelligence (AI) in clinical practice, which are revolutionizing patient care and enhancing diagnostic precision. Furthermore, it highlights the impact of novel serological biomarkers on the understanding and management of immune-mediated optic neuritis, and discusses the introduction of new therapeutic agents like Tocilizumab and Teprotumumab, which are redefining treatment paradigms. Collectively, these advancements reflect the profound influence of modern medicine on neuro-ophthalmology, paving the way for improved patient outcomes and fostering new avenues for research and clinical practice.

Abstract Nocardiosis is an uncommon yet potentially devastating infection. Nocardia tends to affect individuals with chronic lung disease or immunocompromising conditions, 2 groups increasing in number. Incidence of nocardiosis is likely to increase as well, and it is vital to have an approach to this complex disease. Here, we aim to review the presentation, diagnosis, and management of Nocardia in the modern era. We will also highlight areas of uncertainty in our understanding of nocardiosis and propose a general approach to nocardiosis therapy, accounting for response and tolerance of Nocardia treatment.

Background The Minnesota Retaining Employment and Talent After Injury and Illness Network (MN RETAIN) is a randomized controlled study designed to evaluate early interventions promoting workforce retention among workers in Minnesota. The study compares a cohort receiving increased support for stay at work and return to work (SAW/RTW) services from healthcare organizations and resources through workforce development to a control cohort provided solely a list of SAW/RTW resources within the state they can access on their own. Objective This manuscript aims to describe the design of the MN RETAIN Phase 2 study and experience to date including enrollment. Target enrollment for Phase 2 of MN RETAIN is 3200 workers with approximately half receiving SAW/RTW services from a Return-to-Work Case Manager (RWTCM) who is embedded within the healthcare team. MN RETAIN is structured to be accessible to all workers within the state, with a focus on equity and reaching historically underserved populations. Methods Phase 2 of the RETAIN model expanded the focus from the southeast region of MN to state-wide coverage. Enrollment and services were designed to acquire a large enough cohort to reach adequate statistical power to detect differences in disability costs and rates of SAW/RTW in participating study subjects. Impact analysis of RETAIN will be performed by the federal evaluator at a future date. Results Characteristics of enrolled participants to date are summarized as well as considerations for sustainability of the program upon study completion. Conclusions To date, the study has reached diverse workers from throughout the state of MN to provide assistance with SAW/RTW.
