Introduction The rapidly growing population of older adults (individuals aged 65 years and older) presents a new set of challenges for healthcare providers in the emergency department (ED), given the prevalence of severe and life-threatening conditions among this group, such as chronic cancer, Alzheimer’s disease/dementia and congestive heart failure. ED encounters often represent a critical point in an older patient’s trajectory of care and can thus be an important opportunity for various interventions such as palliative care consultation. Therefore, identifying those who will benefit most from palliative care is of high importance, especially in determining the course of future treatment. Thus, we aim to conduct a systematic review assessing the efficacy of palliative care screening in the ED by assessing inpatient length of stay as the primary outcome and quality of life, percentage of hospitalisation and cost of care as secondary outcomes. Methods This study will use Ovid MEDLINE, Embase, EBSCO CINAHL, Web of Science and Cochrane as databases. The study population comprises adults aged 60 years and older, with no focus on any specific clinical specialty or disease. Patients who have not received palliative care screening will serve as the comparator. Only studies with an applicable comparator will be considered. Studies published from 1 January 2000 to 1 July 2025 will be included. All articles will be reviewed independently and in duplicate, and every author will participate in the review, data abstraction and conflict resolution process. Ethics and dissemination Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

Abstract Background Sickle cell disease (SCD) is a hemoglobinopathy with limited treatment options. Genetic modification of the patient's own hematopoietic stem cells (HSCs) offers an avenue to curative therapy using the patient's own cells. Many challenges exist in collecting sufficient numbers of starting material for manufacturing, beginning with the pre‐mobilization optimization of the patient to the mobilization, collection, and post‐collection phases. Study Design and Methods A working group within the Cellular Therapy Subcommittee of the American Society for Apheresis Clinical Applications Committee describes the challenges associated with apheresis collection of the starting material for gene therapy (GT) product manufacturing for patients with SCD and discusses potential strategies for overcoming these challenges. Results and Discussion Patients must undergo automated red blood cell exchange (RCE) to lower hemoglobin S in a relatively short window of time before apheresis collection of HSCs. The risks and benefits of transfusion as well as the logistics of providing adequate and appropriate blood products must be considered. Limited agents are available for mobilization of HSCs into the peripheral blood for collection and the timing of administration is short. Each collection cycle consists of RCE followed by at least three mobilization and apheresis collection events in addition to collecting backup cells. More than one cycle is typically needed to collect enough cells for GT drug product manufacturing. Optimization of patient factors and apheresis instrument parameters leads to better collection yields. Early and frequent ongoing coordination with all stakeholders involved is critical to developing personalized treatment plans for patients.

Peripheral T cell lymphoma (PTCL) is a heterogeneous group of postthymic T cell neoplasms, with ~40% classified as PTCL–not otherwise specified (PTCL-NOS). PTCL-GATA3, a molecularly defined subtype, associated with T helper 2 (T H 2)–like differentiation and poor prognosis, has frequent co-occurrence of TP53 loss/mutation and heterozygous PTEN loss. CD4+ T cell conditional mouse models with Trp53 mutation/deletion and Pten loss demonstrated mature T cell lymphomas (mTCLs) with T H 2-like transcriptomic and immunophenotypic profiles. Molecular studies revealed that codeletion of Trp53/Pten induced T cell receptor and Janus kinase–signal transducer and activator of transcription signaling, promoting T H 2 differentiation while inhibiting T H 1 differentiation. These findings were validated by CRISPR editing of TP53/PTEN loss in human CD4+ T cells and mechanistically evaluated the p53 binding region in intron-3 of GATA3, resulting in transcriptional repression. Transcriptomic profiles of m-TCLs recapitulated human-PTCL-GATA3 transcriptome and distinguished PTCL-NOS subtypes. Preclinical assessment of m-TCLs with PI3Kγ/δ inhibitors significantly improved survival, supporting a therapeutic approach for the p53-aberrant PTCL-GATA3.

Variations in liver allocation systems worldwide are presented, with a specific focus on regional differences and their potential impact on outcomes, with the goal of serving as a reference for future policy development. Summaries of liver allocation across multiple European, Scandinavian, and Asian systems, as well as the combined allocation system of Australia plus Canada, the United States, and the systems in Central America, South America, and the Caribbean are reviewed. A comprehensive comparison of how different regions address MELD exceptions, primarily focusing on hepatocellular carcinoma, along with the most common etiologies of liver disease requiring transplantation is presented. In addition, the adoption of living donation and donation after circulatory death is discussed. The study involves contributions from a diverse group of world experts in liver transplantation and may serve as an essential resource to foster international dialogue as countries strive to optimize organ allocation policies, including MELD exceptions.

Abstract INTRODUCTION Increased white matter hyperintensity (WMH) volume is a common but non‐specific finding in AD. This study investigates the effect of baseline WMH volume and APO E ε4 on magnetic resonance imaging (MRI)‐visible hemorrhagic lesion emergence. METHODS We included A4 participants with 0/1 hemorrhagic lesion at baseline and >1 post‐baseline MRI. We examined age, sex, amyloid, WMH, APOE ε4, and cardiovascular risk as predictors of whether people would accrue ≥2 hemorrhagic lesions by their last MRI. RESULTS Among 1097 individuals with 0/1 baseline lesion, 120 had at least two hemorrhagic lesions on their last MRI. Elevated baseline WMH (odds ratio [OR] = 2.3, p = 0.002) and APOE ɛ4/ɛ4 (OR = 4.8, p < 0.001) independently predicted membership to this group. Both hetero‐ and homozygous APOE ɛ4 carriers with low WMH volume had a low risk of accumulating hemorrhagic lesions. DISCUSSION These results support the independent consideration of WMH and APOE ɛ4 in the natural history of hemorrhagic lesion accumulation and suggest that individuals with low WMH volume have a low short‐term risk, irrespective of APOE genotype. Trial Registration : NCT02008357 Highlights Elevated baseline white matter lesion volume is related to the risk of ARIA‐H emergence. The effects of white matter lesion volume and APOE ɛ4 on ARIA‐H are independent. APOE ɛ4 carriers with low white matter lesion volume had a low risk of ARIA‐H emergence.

Purpose: This study assesses intersurgeon variability in proptosis reduction after orbital decompression for thyroid eye disease. Methods: This multicenter retrospective study included patients with thyroid eye disease who underwent orbital decompression from 1 of 7 surgeons at 7 different institutions between January 2002 and December 2018. Data were included if a single decompression technique was performed on ≥10 patients by ≥2 surgeons. The primary outcome was postoperative change in proptosis with emphasis on comparison among surgeons utilizing similar surgical techniques. Statistical analysis was performed with χ 2 and ANOVA testing, and a multivariable logistic regression model was generated. Results: Six hundred thirty-three orbits that underwent orbital decompression were included. Five different decompression techniques were analyzed: medial wall (n = 29), fat + lateral wall (n = 113), medial wall + floor (n = 123), fat + lateral wall + medial wall (n = 140), and fat + lateral wall + medial wall + floor (n = 228), without significant difference in proptosis reduction among surgeons. Surgeons did not demonstrate significant differences in outcomes at different time points compared with each other or themselves. Outcomes when comparing endoscopic versus open medial wall decompression varied among surgery types. Multivariate modeling revealed a statistically significant association between postoperative change in proptosis with preoperative proptosis ( p < 0.001). Conclusions: Postoperative change in proptosis did not differ significantly between surgeons utilizing similar orbital decompression techniques for patients with thyroid eye disease. This study may strengthen the statistical validity of multicenter clinical trials assessing orbital decompression outcomes performed by surgeons employing uniform surgical techniques, thereby advancing our understanding of optimal surgical management strategies for thyroid eye disease.

Metastatic castration-resistant prostate cancer (mCRPC) progresses aggressively and resists existing therapies. Although poly(ADP-ribose) polymerase inhibitors (PARPis) benefit a subset of patients with mCRPC and BRCA1/2 deficiencies, therapeutic options remain limited for those without such mutations. Here, we uncover a critical role for the ATM-TRMT10A-BRCA1 signaling axis in regulating homologous recombination (HR) repair and PARPi sensitivity. We demonstrate that ATM phosphorylates TRMT10A at serine-28 after DNA damage, promoting BRCA1 recruitment and efficient HR repair. TRMT10A deletion disrupts HR repair, sensitizing cells to PARPis. Moreover, TRMT10A is up-regulated in mCRPC through stabilization by USP10. Targeting USP10 with spautin-1 induces TRMT10A degradation and enhances tumor sensitivity to PARPis in cell-derived xenografts and patient-derived xenograft models. These findings identify TRMT10A as a therapeutic vulnerability in mCRPC and demonstrate that combined inhibition of PARP and USP10 offers a promising synthetic lethal strategy for a broader group of patients lacking classical BRCA mutations.

Background: Thyroid eye disease (TED) is a debilitating autoimmune disorder linked to thyroid dysfunction. There is limited knowledge of TED in Asian populations. This multicenter study characterizes the clinical features and treatment response of TED in a large Chinese cohort. Methods: A retrospective multicenter study included 4157 patients with TED from nine Chinese hospitals from February 2016 to July 2023. Disease severity and activity were evaluated according to the European Group on Graves’ Orbitopathy standards. We examined associations of variables including sex, age, smoking status, I 131 treatment, consultation department, and geographical region with clinical outcomes. Logistic regression and nomogram models were developed to examine associations with sight-threatening TED and, in a subgroup analysis ( n = 126), patients’ responsiveness to intravenous glucocorticoid (IVGC) therapy. Results: We included 4157 patients with mean age and standard deviation (SD) 45.96 ± 16.44 years. Of these, 63.6% ( n = 2644) were females. Over half (55.6%, n = 2310) of participants were in the inactive phase, with a mean clinical activity score of 2.19 ± 1.61 (SD) for all patients. TED severity was categorized as mild (9.3%, n = 385), moderate-to-severe (82.5%, n = 3428), and sight-threatening (8.2%, n = 344). The average degree of exophthalmos was 20.04 ± 5.27 mm, and 48.8% ( n = 2029) of patients had diplopia. Patients treated with I 131 had higher disease activity (47.5%, n = 468, vs. 43.5%, n = 1379, p < 0.05). Coastal region patients exhibited more severe TED (sight-threatening cases: 10.1%, n = 195, vs. 7.2%, n = 147) and higher diplopia scores (1.00 ± 1.10 vs. 0.86 ± 1.09, p < 0.001) than inland counterparts. TED severity was also greater in patients treated in Ophthalmology departments (mild cases: 6.0%, n = 213; moderate-to-severe cases: 85.6%, n = 3055) compared with Endocrinology departments (mild cases: 29.3%, n = 172; moderate-to-severe cases: 63.5%, n = 373). Nomograms had an area under the receiver operating curve of 0.742 (confidence interval [CI] 0.716–0.768) for sight-threatening TED and 0.759 (CI 0.674–0.843) for IVGC therapy responsiveness. Conclusions: We characterized the clinical features and treatment response of TED in a large Chinese cohort. These findings offer valuable insights informing TED risk stratification in Asian patients and forming a foundation for future prospective studies.

Background: Cardiac fibrosis is a central pathological process that leads to worse outcomes in various cardiomyopathies. Recent evidence shows that CDCP1 (CUB domain-containing protein 1) modulates myocardial recovery by attenuating human cardiac fibroblast (HCF) proliferation. This study investigates the hypothesis that selective targeting of the CDCP1 cleavage domain can mitigate fibroblast proliferation, thereby offering a novel therapeutic approach to reducing cardiac fibrosis. Methods: A high-throughput in silico screening was performed using the Enamine compound library, focusing on structural regions that include the cleavage and adjacent sites of CDCP1 . A total of 147 candidate compounds were prioritized based on docking scores and binding stability profiles. Selected compounds were subsequently evaluated in vitro using HCF cultures seeded at 3,000 cells/well in 96-well plates. Each compound was administered at 10 μM concentration, and cell proliferation and viability were assessed by time-lapse imaging in the Incucyte® system at 24 and 96 hours. All experiments were done in triplicate with appropriate DMSO vehicle controls. Results: Compound C3 significantly reduced HCF proliferation (Fig B) to 27.3±2.4% relative to DMSO controls (99.9±0.5%, P <0.001) at 96 hours. Detailed structural modeling indicated that C3 binds to the CDCP1 cleavage site (Fig C) with a favorable Glide XP docking score of -7.66 kcal/mol. The interaction is stabilized by hydrogen bonds with Lys365 and Cys374 (Fig D), and supplementary hydrophobic interactions between aromatic rings and aliphatic groups, which contribute to a strong inhibitory effect. Conclusion: Targeting the CDCP1 cleavage domain with compound C3 effectively diminishes HCF proliferation in vitro. Therefore, these results substantiate the therapeutic potential of CDCP1 inhibition in cardiac fibrosis. Ongoing in vivo studies will explore the translational relevance of these findings.
