These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. They are intended to assist oncology teams to identify patients who require referral to psychosocial resources and to give oncology teams guidance on interventions for patients with significant distress. These guidelines also provide guidance for social workers, certified chaplains, and mental health professionals by describing treatments and interventions for various psychosocial problems as they relate to patients with cancer. These NCCN Guidelines Insights summarize the panel’s most recent recommendations regarding standards of care for distress management in patients with cancer and implementation of these standards, including application of evidence-based care delivery models, such as the collaborative care model.

Introduction: Online self-triage is a newer eHealth modality, and there is a paucity of research on patient adherence to self-triage recommendations. We evaluated patient compliance with online self-triage guidance to seek emergency care and compared to nurse-triage adherence rates. Methods: We reviewed primary care empaneled patients who had either nurse phone triage or an online self-triage encounter that resulted in an emergency care recommendation between January 1, 2023, and November 30, 2024. Patients triaged for mood concerns, abdominal pain, chest pain, constipation, cough, and diarrhea were included. We reviewed whether patients had an emergency department visit within 24 h of their triage encounter. For self-triage encounters, we also examined whether patients called nurse triage within 24 h of their self-triage encounter. Results: There were 689 self-triage and 2,385 nurse triage encounters with an emergency care endpoint. Adherence to the emergency care recommendation was substantially lower after self-triage (22%) than after nurse triage (61%). Patients who underwent nurse triage were significantly more likely to seek emergency care than those who self-triaged (odds ratio of 5.4 [95% CI: 4.5–6.6] p < 0.001). Both male and female patients were less likely to follow emergency care recommendations after self-triage compared to nurse triage ( p < 0.001). There were 258 patients with an emergency care endpoint from self-triage who chose to call nurse triage (median time between encounters of 16 min). Only 78 (30.2%) also received an endpoint recommendation for emergency care, and 73% of those patients sought emergency care within 24 h. Discussion: Patient compliance with online self-triage recommendations to seek emergency care was poor and significantly less than nurse triage. Follow-up calls to nurse triage led to higher compliance. Health systems using online symptom checkers should consider employing mechanisms to follow up on emergency care recommendations. Further research should elucidate factors that contribute to patients’ willingness to follow care recommendations.

Objective Immunohistochemically (IHC) measured transactive response DNA‐binding protein 43 (TDP‐43) inclusions are observed in Alzheimer's disease (AD) and are associated with medial temporal lobe atrophy. Accumulation of cryptic exons occurs in AD in response to TDP‐43 pathology. We aimed to assess relationships between IHC and biochemically measured insoluble TDP‐43 and cryptic exons and assess associations with hippocampal and amygdala volume loss and atrophy rates on magnetic resonance imaging (MRI). Methods Eighty‐one neuropathologically diagnosed AD cases were analyzed. For biochemistry, insoluble TDP‐43 was quantified using a Meso‐scale discovery (MSD) immunoassay. IHC‐TDP burden was quantified with digital histopathology. Cryptic RNAs were assessed via quantitative real‐time polymerase chain reaction (qRT‐PCR). Thirty‐eight cases had serial brain MRI. Hippocampal and amygdala volumes were calculated using FreeSurfer. Regression models were used to investigate associations among IHC‐TDP‐43 status/burden, MSD‐TDP status/levels, cryptic RNAs, and hippocampal and amygdala volumes and atrophy rates. Results IHC‐TDP(+) cases exhibited elevated levels of MSD‐TDP and cryptic RNAs ( KCNQ2 , STMN2 , and UNC13A ) and increased MSD‐TDP levels were associated with increased cryptic RNA levels, in the hippocampus and amygdala. IHC‐TDP(+) cases had smaller hippocampal and amygdala volumes compared to IHC‐TDP(−) cases. MSD‐TDP(+) cases had smaller hippocampal volumes and faster amygdala rates of atrophy compared with MSD‐TDP(−) cases. Higher KCNQ2 and UNC13A levels were associated with smaller amygdala volumes. Interpretation MSD‐TDP level is a reliable surrogate for IHC‐based TDP‐43 status. Both TDP‐43 and cryptic RNA levels are associated with reduced medial temporal volumes, suggesting cryptic exons may be playing a role in brain volume loss in AD. ANN NEUROL 2026;100:193–205

Objective We investigated potential racial disparities in the effects of audiometric hearing loss and its treatment on dementia and mortality among 3,602 older adults aged 68–89 years, 22% of whom were self-identified Black race. Methods Adjudicated all-cause dementia was determined using neurocognitive test data, proxy reports, and surveillance of hospital records and death certificates. Audiometric hearing loss, defined as the better-ear averaged pure-tone threshold (0.5–4 kHz), was categorized using clinical cutpoints. Multivariable-adjusted Cox proportional hazards models included hearing loss–race interaction terms. Results Dementia risk associated with moderate-to-severe hearing loss did not differ by race [Black participants: hazard ratio (HR): 1.66; 95% confidence interval (CI): 1.05, 2.61; White participants: HR: 1.71; 95% CI: 1.16, 2.51; P -interaction = 0.92]. However, moderate-to-severe hearing loss was associated with a 2.3-fold increase in mortality among Black participants only (95% CI: 1.17, 4.60). Conclusions Our findings emphasize the importance of including minoritized populations in hearing treatment research to build an evidence base for policy development and clinical decision-making. Hearing loss affects the health of both Black and White Americans. Racial disparities in hearing healthcare should be addressed to advance health equity for all older adults.

ABSTRACT Introduction It is controversial whether surgical correction of tethered spinal cord in non‐myelomeningocele tethered cord patients results in reversal versus stabilization of urologic (GU), gastrointestinal (GI), and musculoskeletal (MSK) symptoms. Objective To determine factors associated with clinical improvement in symptoms after spinal cord de‐tethering, and evaluate whether pre‐operative urodynamic testing predicts post‐operative clinical outcomes. Methods 213 non‐myelomeningocele children who underwent primary spinal cord de‐tethering at a quaternary children's hospital from 2012 to 2020 were retrospectively reviewed. Age at surgery, gender, and presence of GU symptoms, constipation, MSK symptoms, and urodynamic studies were collected. Pre‐operative symptoms and demographics were compared between patients with and without resolution of GU symptoms after surgery. Results Mean age at surgery was 5.36 years, 48% were female, and mean length of follow up was 1.8 years. Before surgery, 133/213 (62%) experienced a GU symptom. 105/213 (49%) patients were potty‐trained. Of 105 potty‐trained patients, 50 (48%) had daytime incontinence and 55 (52%) had nocturnal enuresis. Of 88 potty‐trained patients with urinary symptoms, 22 (25%) had resolution of and 59 (67%) had improvement following surgery. Of the 102 with constipation, 45 (44%) had improvement. Of the 116 with musculoskeletal symptoms, 60 (52%) had improvement. Patients with resolution of GU symptoms were younger (4.97 vs. 8 years, p = 0.0019). Patients with daytime urinary incontinence ( p = 0.0119) were less likely to have resolution of GU symptoms. There was no difference in urodynamic findings between patients with and without improvement or resolution of urologic symptoms. Conclusion Younger age at de‐tethering surgery is associated with improvement in genitourinary symptoms. Preoperative urodynamic studies may not be predictive of postoperative outcomes.

Abstract Background Anti‐M antibodies were described as rarely eliciting hemolytic disease of the fetus and newborn (HDFN) in pregnancy. More recent literature, primarily from Asia, reports severe HDFN attributed to maternal anti‐M. The objective of this study is to determine if there is a difference in the frequency and/or severity of anti‐M HDFN among subjects who self‐report as Asian compared to non‐Asian. Methods Retrospective data were collected from 18 sites. Fetuses/neonates affected by HDFN were categorized as unaffected, mild, moderate, or severe based on clinical management and outcomes. Results Anti‐M was identified in 557 obstetric patients. Among 332 neonates with complete data for analysis, anti‐M was detected in isolation during the pregnancies of 210 (63.3%) neonates; 198 (94.3%) were unaffected by HDFN. The overall frequency of HDFN was 6.5% (2/31) in Asian patients and 5.6% (10/179) in non‐Asian patients. The frequency of severe HDFN was 6.5% (2/31) among Asian patients and 0.6% (1/179) among non‐Asian patients. Among non‐Asian patients, eight (4.5%) were mild and one (0.6%) was moderate. Of 63 pregnancies with anti‐M and ABO incompatibility, 6 (9.5%) were associated with mild HDFN and 57 (90.5%) were unaffected. Of 49 pregnancies with anti‐M and non‐ABO antibody(s), 6 (12.2%) were associated with mild HDFN and 43 (87.8%) were unaffected. One case (10.0%) of HDFN (mild) occurred in the presence of anti‐M, additional antibody(s), and ABO incompatibility. Conclusion In this study, severe anti‐M HDFN was rare in non‐Asian subjects. There is a signal that Asian patients are at greater risk for severe anti‐M HDFN.

Critically ill patients frequently require intrahospital transport (IHT) to diagnostic exams or procedures and must remain connected to life-sustaining medical lines. During IHT, the risk of tangled medical lines is unavoidable. The idea for a novel medical line securement device was inspired by a patient transport nurse due to frustrations and workflow inefficiencies managing tangled medical lines. The study aim was to explore the correlation between the utilization of a single-use securement device to manual or accidental disconnections of medical lines during IHT, and nurses’ perception of efficiency, compared to the current practice of no utilization of a securement device. In 2019, a randomized, descriptive, correlational study was conducted on 142 progressive and intensive care hospitalized patients. Study coordinators measured the number of times either IV lines or monitor cords were accidentally or manually disconnected to detangle during or after transportation and the perception of transport efficiency. Results revealed fewer manual disconnections among intervention group compared to the control. Nurses’ perception regarding the efficiency between the intervention and control group was statistically significant when the device was utilized to secure the lines and cords during transport. Nurses reported much higher satisfaction rates of transport efficiency when the device was used. This finding showed the device’s utility for improving nurse satisfaction during IHT of critically ill patients. Utilization of the medical line securement device may be generalizable across other healthcare settings and disciplines where the complexity of medical lines may exist.

Abstract Background: Cholangiocarcinoma (CCA) is an aggressive hepatobiliary malignancy with limited treatment options. CCA exhibits a distinct desmoplastic and tolerogenic tumor immune microenvironment (TIME) characterized by elevated bile acid concentrations resulting from obstructive cholestasis and dysregulated bile acid metabolism. TGR5 is an essential component of bile acid signaling. We hypothesize that bile acids promote CCA progression by establishing an immunosuppressive TIME through TGR5 signaling, which can be therapeutically targeted using SBI-364, a novel potent small molecule TGR5 inhibitor. Methods: Single-cell RNA sequencing (scRNA-seq) of immune cells from human intrahepatic (iCCA) and perihilar (pCCA) CCA tumors were conducted. Therapeutic studies were performed using syngeneic murine models of iCCA (PMID: 38458319), a novel syngeneic model of pCCA, and patient-derived xenograft (PDX) models. In collaboration with Sanford Burnham Prebys, SBI-364, a first in-class competitive TGR5 antagonist, was assessed in vivo. Additionally, we performed co-culture experiments with bile acid +/- SBI-364-treated murine bone marrow-derived monocytic myeloid-derived suppressor cells (M-MDSCs) and CD8+ T cells to assess functional immunosuppressive effects. Results: Human scRNA-seq revealed significantly increased TGR5 (GPBAR1) expression predominantly in myeloid cell populations within the CCA TIME. SBI-364 treatment significantly reduced tumor burden in both syngeneic orthotopic iCCA models and a novel pCCA model that recapitulates the anatomic characteristics of perihilar CCA. In contrast, NOD/SCID mice bearing PDX535 (predicted sensitive) and PDX136 (predicted resistant), SBI-364 treatment did not achieve tumor reduction, suggesting that TGR5 inhibition predominantly attenuates tumor progression through modulation of bile acid-immune cell interactions. SBI-364 treated murine tumors had a significant reduction in immunosuppressive macrophages expressing interleukin-10 and M-MDSCs compared to vehicle treated tumors. Furthermore, bile acid-treated M-MDSCs exhibited enhanced suppression of CD8+ T cell proliferation and function, an effect that was abrogated by SBI-364 co-treatment. Conclusion: We demonstrate that TGR5 inhibition represents a promising therapeutic strategy across multiple immunocompetent preclinical CCA models. We demonstrate that the bile-acid TGR5 axis promotes CCA progression via immunosuppressive myeloid cells. Specifically, TGR5 signaling potentiates the immunosuppressive capacity of M-MDSCs, contributing to an immunosuppressive niche that facilitates tumor progression. These results establish TGR5 as a rational therapeutic target for overcoming immune evasion in cholangiocarcinoma.

Abstract Background: Diffuse pleural mesothelioma (DPM) is a highly aggressive malignancy with limited treatment options and poor prognosis. Although immune checkpoint inhibitors have improved outcomes, particularly for non-epithelioid subtypes, there remains no approved targeted therapy for mesothelioma. EGFR and MET are receptor tyrosine kinases frequently overexpressed in DPM, suggesting susceptibility to targeted antibody therapy. Amivantamab is a bispecific EGFR/MET antibody, originally developed for EGFR-mutant lung cancer, that blocks growth signals and engaging immune mechanisms. Given the high levels of EGFR and MET expression in mesothelioma, we evaluated the therapeutic potential of amivantamab in preclinical models. Methods: EGFR and MET transcript levels in DPM were analyzed using TCGA. Eight human mesothelioma cell lines were assessed by Western blotting and flow cytometry. Amivantamab binding, internalization, and signaling inhibition were examined using flow cytometry, confocal microscopy, and ligand-stimulated phosphorylation assays. Cytotoxicity and immune-effector activity were quantified using PBMCs, NK cells, and monocytes from healthy donors, along with an ADCC reporter assay. In vivo efficacy was tested in a DPM patient-derived xenograft (PDX) model in NOD/SCID-γ (NSG) mice supplemented with human NK cells and treated with amivantamab or control IgG. Results: TCGA analysis showed frequent EGFR/MET co-expression in DPM. Mesothelioma cell lines expressed higher EGFR and MET levels compared with mesothelial cells. Amivantamab strongly bound both receptors, induced receptor internalization, and inhibited EGF- and HGF-stimulated phosphorylation of EGFR, MET, and downstream AKT/ERK signaling. Direct cytotoxicity was minimal; however, the addition of PBMCs or NK cells resulted in robust, dose-dependent tumor cell killing consistent with antibody-dependent cellular cytotoxicity (ADCC). Reporter assays demonstrated 7-11-fold Fcγ receptor activation in tumor cells compared with ∼2-fold activation in non-malignant mesothelial cells. Co-culture with monocytes revealed amivantamab-induced trogocytosis, evidenced by loss of EGFR and MET from tumor-cell membranes. In the DPM PDX model, amivantamab produced 89.1% tumor-growth inhibition (TGI) relative to controls (P &lt; 0.0001), with no overt toxicity observed in treated mice. Conclusions: Dual EGFR/MET targeting with amivantamab produced potent antitumor effects in mesothelioma through coordinated receptor-signaling blockade, ADCC, and monocyte-mediated trogocytosis. These results support amivantamab as a promising targeted therapeutic strategy for EGFR/MET-positive DPM, particularly epithelioid subtypes that currently derive limited benefit from immunotherapy.

Abstract Background: Most colorectal cancer (CRC) arises from polyps and is mainly prevented by polypectomy. The most important polyps to manage with colonoscopy are those with highest CRC risk- namely, advanced polyps (&gt; 1cm, villous histology or high-grade dysplasia (HGD). Yet, 48% of advanced polyps recur within 1 to 3 years of removal, and up to 5% of advanced polyps under surveillance still progress to CRC. We performed this pilot study to investigate molecular and microenvironment heterogeneities of polyps and how they might impact their clinical behavior. Methods: GeoMx spatial transcriptomics was performed on FFPE tissues from three different polyp outcome phenotypes (POPs) including the polyp that does not recur (POP-NR), that recurs following polypectomy but cured by colonoscopy (POP-R) or the polyp despite polypectomy develops CRC at the polypectomy(ies) site (POP-CRC). Normal colon and polyp with low or HGD from the index polyp were assessed from 6 patients with POP-NR, 9 with POP-R and 12 with POP-CRC with a minimum of 2 follow up colonoscopies at 3-year intervals. Epithelium was identified as PanCK positive, and stroma identified as PanCK negative and positive nuclear staining. Cell type deconvolution was implemented using single-cell adult human intestinal tract catalogue (Elmentaite et al., https://www.gutcellatlas.org/). Differential gene expression (DEG), cell type abundance and functional enrichment analyses was performed using linear mixed effects model, and observations with p-value &lt; 0.05 and log2FC &gt;= |1| are reported. Results: The greatest number of DEGs were identified in stroma of the index POP-CRC compared to POP-NR polyps (n = 17 down and 11 upregulated genes), followed by epithelium of the index POP-CRC vs POP-NR polyps (n = 10 down and one upregulated gene(s)). Between the index POP-CRC and POP-R, epithelium showed downregulation of 7 genes, and upregulation of no genes. In stroma two genes were down and none upregulated. Four genes were downregulated in stroma of the index POP-R vs POP-NR polyp and 3 in epithelium, and one gene was upregulated in stroma and another in epithelium. MZT2B was upregulated in stroma of both the index POP-R (log2FC = 1.09, p-value = 0.0014) and POP-CRC (log2FC = 1.29, p-value = 0.0001) and has been implicated as a prognostic marker associated with worse prognosis in certain cancers. IgM and IgA plasma cells, proximal progenitors, MMP9+ inflammatory macrophages and myofibroblasts were found to be downregulated in epithelium of index POP-CRC and POP-R compared to POP-NR polyps; while microfold cells were downregulated in stroma of index POP-CRC and POP-R compared to POP-NR polyps. Conclusions: The stromal microenvironment and less so, epithelial features present in the index polyp differ based on a polyp’s future clinical behavior. The polyp-immune interaction warrants further study as a potential prevention target against polyp progression. Citation Format: Mrunal Dehankar, Lisa A. Boardman, Daniel O'Brien, E.
