Despite significant improvements in survival of patients with multiple myeloma (MM), outcomes remain heterogeneous, and a significant proportion of patients experience suboptimal outcomes. Importantly, traditional prognostic factors based on data from patients treated with older therapies no longer capture prognosis accurately in the contemporary era of novel triplet or quadruplet therapies. Therefore, risk stratification requires refinement in the context of available and investigational treatment options in routine practice and clinical trials, respectively. The current identification of high-risk MM (HRMM) in routine practice is based on the Revised International Staging System, which stratifies patients using a combination of widely available serum biomarkers and chromosomal abnormalities assessed via fluorescence in situ hybridization. In recent years, a substantial body of evidence concerning additional clinical, biological, and molecular/genomic prognostic factors has accumulated, along with new MM risk stratification tools and consensus reports. The International Myeloma Society, along with the International Myeloma Working Group, convened an Expert Panel with the primary aim of revisiting the definition of HRMM and formulating a practical and data-driven consensus definition, based on new evidence from molecular/genomic assays, updated clinical data, and contemporary risk stratification concepts. The Panel proposes the following Consensus Genomic Staging (CGS) of HRMM which relies upon the presence of at least one of these abnormalities: (1) del(17p), with a cutoff of >20% clonal fraction, and/or TP53 mutation; (2) an IgH translocation including t(4;14), t(14;16), or t(14;20) along with 1q+ and/or del(1p32); (3) monoallelic del(1p32) along with 1q+ or biallelic del(1p32); or (4) β2 microglobulin ≥5.5 mg/L with normal creatinine (<1.2 mg/dL).

Rashes are a common issue in primary care, encompassing various differential diagnoses. Chilblain lupus erythematosus (CHLE), a subset of cutaneous lupus erythematosus (CLE), is a rare skin condition with limited documented cases. A young male patient presented with purple discoloration of his toes and fingers, along with violaceous skin scaling after exposure to cold temperatures. A positive antinuclear antibody test led to the diagnosis of CHLE and the initiation of treatment, resulting in a positive response.

Abstract Inotuzumab ozogamicin (InO) is an antibody-calicheamicin conjugate with high efficacy in lymphoid malignancies. It targets the B-cell surface protein CD22, which is expressed in most B-cell acute lymphoblastic leukemia (B-ALL) cases, albeit with variable intensity. However, factors governing CD22 expression and thus leukemia sensitivity to InO remain incompletely understood. Using multiomic characterization of 196 human B-ALL samples, coupled with ex vivo InO sensitivity profiling, we showed that early leukemia differentiation arrest at the pre–pro-B stage is associated with resistance to InO. Screening of 1639 transcription factor genes identified early B-cell factor 1 (EBF1) as a key regulator of CD22 expression (false discovery rate of 7.1 × 10−4). When comparing the assay for transposase-accessible chromatin with sequencing profiling results of the most InO-sensitive and -resistant cases (50% lethal concentration &lt;10th vs &gt;90th percentile, n = 18), the binding motif for EBF1 was strikingly enriched in regions with differential open chromatin status (P = 8 × 10−174). CRISPR interference targeting EBF1 binding sites at the CD22 locus led to an ∼50-fold reduction in cell surface CD22 expression and, consequently, an ∼22-fold increase in InO resistance in ALL cell lines. Interestingly, within BCR::ABL1 ALL, we observed intrasubtype heterogeneity linked to EBF1 transcriptional downregulation (P = 1.1 × 10−15) and/or somatic alteration (P = .004), which led to reduced CD22 expression (P = 8.3 × 10−11) and ex vivo and in vivo resistance to InO. Collectively, these findings point to the direct impact of EBF1 on CD22 expression during B-cell development, which, in turn, contributes to interpatient variability in InO response, even within the same subtype of B-ALL.

Background Heart failure (HF) is a growing public health burden. Systemic inflammation is commonly observed in patients with HF and believed to be related to disease pathogenesis. Infection is a potential acute trigger of chronic inflammation. Our objective was to examine the relationship between infection‐related hospitalization (IRH) and HF. Methods and Results We studied beneficiaries with at least 15 months of continuous enrollment in the US‐based MarketScan databases during 2013 to 2019. We included n=152 008 patients with an inpatient or outpatient HF International Classification of Diseases, Ninth Revision/Tenth Revision ( ICD‐9/10 ) code in the primary position. Among patients with HF, IRH was identified using select ICD‐9/10 codes. We used a case‐crossover design to compare the frequency of IRH occurring within 3 months of the index HF event (case period) versus the frequency of IRH occurring 12 to 15 months before the index HF event (control period). Logistic models regressed the log‐odds of having an IRH during the case versus control periods; odds ratios (ORs; 95% CIs) are presented. Among 152 008 beneficiaries, 53% were male with a mean±SD age of 56(±11) years. The odds of having an IRH during the case (versus control) period was elevated for both the 3‐month case period (OR, 4.39 [95% CI, 4.18–4.60]), and 1‐month case period (OR, 7.39 [95% CI, 6.88–7.94]), after adjusting for the total number of hospitalizations. This relationship persisted across different types of infections. Conclusions IRH was associated with incident HF after both 1 and 3 months and may represent a modifiable risk factor for HF.

Summary The eosinophilic esophagitis (EoE) Endoscopic Reference Score (EREFS) measures endoscopic severity. While a score of ≤2 has been proposed for endoscopic response, it is unknown whether achieving this threshold results in clinically important outcomes. We aimed to determine whether an EREFS response to topical steroids (tCS) is associated with a decreased need for future esophageal dilation. In this retrospective cohort study, we included patients with a new diagnosis of EoE who underwent esophageal dilation, were then treated with tCS, and had at least two follow-up endoscopies. Endoscopic response was defined as EREFS ≤2. Histological and global symptom responses were recorded. We compared patients with and without endoscopic response and calculated the number of subsequent dilations in each group. Of 113 EoE patients, 55 (49%) had endoscopic response post-tCS. Compared to endoscopic non-responders, responders were older (43.4 vs 34.4 years; p = 0.001) and had lower EREFS (4.4 ± 1.6 vs. 6.3 ± 1.5; p &lt; 0.001) at baseline. EREFS responders required fewer dilations on their initial post-treatment endoscopy (65% vs 90%; p = 0.002) and had greater symptom (92% vs 64%; p = 0.005) and histologic responses (82% vs 24% &lt;15 eos/hpf; p &lt; 0.001). Over the median follow-up time of 1106 days, EREFS responders required fewer dilations than non-responders (4.5 ± 2.9 vs 6.2 ± 4.5; p = 0.03). Endoscopic responders to tCS required fewer esophageal dilations compared to non-responders. Responders also had better symptom and histologic responses. These results provide evidence that endoscopic response is associated with important clinical outcomes including a reduction in future esophageal dilations.

PURPOSE The combination of the Bruton tyrosine kinase inhibitor ibrutinib with bendamustine-rituximab for first-line treatment of mantle cell lymphoma (MCL) prolonged progression-free survival (PFS), but without improvement in overall survival (OS), likely because of toxicity. Acalabrutinib was shown to be efficacious and less toxic than ibrutinib in a head-to-head trial in chronic lymphocytic leukemia and therefore might lead to better outcomes in MCL. METHODS Patients 65 years and older with previously untreated MCL received acalabrutinib (100 mg twice daily) or placebo (until disease progression or unacceptable toxicity), plus six cycles of bendamustine (90 mg/m 2 once daily; days 1 and 2) and rituximab (375 mg/m 2 as a single dose; day 1) followed by rituximab maintenance in responding patients for 2 years. Crossover to acalabrutinib at disease progression was permitted. The primary end point was PFS per the independent review committee; overall response rate and OS were secondary end points. RESULTS In total, 598 patients were randomly assigned, with 299 in each arm. At a median follow-up of 49.8 months using the reverse Kaplan-Meier method, the median PFS was 66.4 months in the acalabrutinib arm and 49.6 months in the placebo arm (hazard ratio [HR], 0.73 [95% CI, 0.57 to 0.94]; P = .0160). Benefit was seen across all subgroups, including those with high-risk features. Overall response/complete response rates were 91.0%/66.6% and 88.0%/53.5% in the acalabrutinib and placebo arms, respectively. OS was not significantly different (HR, 0.86 [95% CI, 0.65 to 1.13]; P = .27). Grade 3 or greater adverse events were reported in 88.9% and 88.2% in the acalabrutinib and placebo arms, respectively. CONCLUSION The combination of acalabrutinib with bendamustine-rituximab significantly improved PFS. Clinical benefit of acalabrutinib with bendamustine-rituximab was achieved with manageable toxicity.

ABSTRACTIntroduction/AimsPacinian corpuscles are end organs of the sensory nervous system. The size and superficial location of Pacinian corpuscles allows them to be visualized with high‐resolution ultrasound. This pilot study sought to assess the reliability of Pacinian corpuscle counting in the hand using ultrasound.MethodsTwo healthy participants underwent ultrasound evaluation by three ultrasonographers using a scanning protocol developed for this study. The ultrasound protocol used anatomic landmarks to identify and trace digital nerves in the palms and the adjacent Pacinian corpuscles. The ultrasonographers used morphologic features to identify and count Pacinian corpuscles at two sites in each hand for each participant using a 10–22 MHz linear‐array transducer. The procedure was repeated at 2 time points. Inter‐rater and intrarater reliabilities were determined using intraclass correlation coefficients (ICCs).ResultsPacinian corpuscles were identified in the second–third and fourth–fifth intermetacarpal spaces. The ultrasound appearance of Pacinian corpuscles is of a hypoechoic, rounded structure without a hyperechoic rim. A clustered appearance and septate internal structure are distinct features of Pacinian corpuscles, but these features are not always present. The mean number at each site was between 10.71 and 11.71. Inter‐rater and intrarater reliability both resulted in ICC values over 0.8, indicating “good” inter‐rater and intrarater reliabilities.DiscussionPacinian corpuscles can be reliably counted in the hand using high‐resolution ultrasound. The reliability data from this pilot study may facilitate further ultrasound studies of Pacinian corpuscles, which may be decreased in number or undergo other changes in polyneuropathies.

Introduction: Physical activity (PA) has been identified as a protective factor for dementia, but the mechanisms linking PA to brain health are unclear. To elucidate potential pathways linking PA to brain health, we tested the hypothesis that higher levels of late-life PA are associated with a lower burden of Alzheimer’s disease (AD) pathology, cerebrovascular disease, and neurodegeneration measured through brain imaging and plasma biomarkers. Methods: ARIC-NCS participants without dementia in 2011-13 and with measures of PA, 3T brain magnetic resonance imaging (MRI), and stored plasma samples were examined (n=1,771; mean age: 76.5 years; 40.5% male; 27.6% Black). Participants were classified as meeting or not meeting 2018 aerobic PA guidelines based on a standardized interviewer-administered questionnaire. MRI biomarkers included white matter hyperintensity (WMH) volume (cm 3 ), total brain volume (TBV) (cm 3 ), and cortical thickness (CT) (mm). Plasma biomarkers of the ratio of amyloid beta 42 to 40 (Aβ42/Aβ40), phosphorylated Tau-181 (p-Tau181), neurofilament light chain (NfL), and glial fibrillary acidic protein (GFAP) were measured using Quanterix Simoa immunoassays. All biomarkers were standardized to measures in 2011-13 to facilitate comparisons. Covariate-adjusted linear regression models estimated cross-sectional associations of PA with MRI or plasma biomarkers. Covariate-adjusted linear mixed effects models quantified associations of PA with the 5-year rate of change in a subset of participants with MRI (n=669) or plasma (n=651) biomarkers at both baseline and follow-up from 2011-19 (median follow-up: 5.4 years). Results: Meeting versus not meeting aerobic PA guidelines was cross-sectionally associated with lower volumes of WMH (β = -0.16, 95% CI: -0.25, -0.07), higher TBV (β = 0.09; 95% CI: 0.05, 0.13), and lower plasma NfL (β = -0.102, 95% CI: -0.184, -0.021) ( Figure ). Late-life PA was not associated with 5-year rates of change in MRI or plasma biomarkers. Conclusions: Late-life PA was cross-sectionally associated with less neurodegeneration and cerebrovascular disease. Associations with 5-year changes in imaging and plasma biomarkers of AD pathology, cerebrovascular disease, or neurodegeneration were not statistically supported. Longitudinal biomarker studies with wearable devices that quantify other daily intensity-based movement metrics (e.g., light PA) and larger sample sizes are needed to further examine mechanisms linking PA to brain health.

Chronic pain is a pervasive and complex symptom experienced by patients with Systemic Lupus Erythematosus (SLE), often impacting their quality of life. Traditional data sources, such as clinical records and surveys, provide valuable insights but may not fully capture the breadth of patient experiences and self-management strategies. This study leverages Reddit discussions as a real-world data source to explore chronic pain patterns, management approaches, and unmet needs among individuals with SLE. Utilizing natural language processing (NLP), we analyzed over 30,000 posts from r/Lupus and r/LupusSupport subreddits to identify key themes, trends, and alternative therapies discussed by users. This approach highlights the potential of social media as a complementary resource for understanding chronic pain and guiding patient-centered care interventions.
