PURPOSE This national study was undertaken to determine screening mammography rates among transgender and gender diverse (TGD) individuals. METHODS TGD individuals and cisgender women who qualified to receive screening mammography based on American College of Radiology guidelines were identified in the longitudinal OptumLabs Data Warehouse. The primary end point was the percentage of patients who had high rates of screening (>75% recommended screenings). Multivariable analyses were conducted in a matched population of transgender men to cisgender women to identify and adjust for factors associated with high adherence. Individuals were matched at a 1:4 ratio (transgender men: cisgender women) on age, race/ethnicity, year of enrollment in their health care plan, and duration of follow-up. RESULTS This study focused on 10,478 TGD individuals (3,778 transgender men; 1,294 transgender women; 5,406 with gender dysphoria not meeting other TGD criteria, NMOT) and 6,218,369 cisgender women. For transgender men, transgender women, individuals with gender dysphoria NMOT, and cisgender women, high mammography rates were observed in 41.1% (95% CI, 39.5 to 42.6), 7.4% (95% CI, 6.0 to 8.8), 11.9% (95% CI, 11.0 to 12.7), and 38.3% (95% CI, 38.3 to 38.4), respectively ( P < .0001). When transgender men were compared with 15,112 matched cisgender women, an age-based differential association was observed between sex and high mammography rates (interaction P = .0003); compared with cisgender women, transgender men appeared more likely to manifest high rates of screening at age 40-49 years (odds ratios [ORs], 1.38 [95% CI, 1.28 to 1.50]; P < .0001) and 50-59 years (OR, 1.57 [95% CI, 1.35 to 1.81]; P < .0001) but not in the older age groups. CONCLUSION The relatively high rates of screening mammography in cisgender women and transgender men suggest clinicians are offering mammography to individuals who are at average or high breast cancer risk, as compared with cisgender women, and not to transgender women at low risk.

Abstract Cellular senescence has been implicated in the pathophysiology of radiotherapy-related bone loss. Based on our previous work, clearance of senescent cells using genetic and pharmacological tools alleviates the anomalies associated with radiation-associated bone deterioration. The pro-inflammatory senescence associated secretome referred to as senescence associated secretory phenotype (SASP), is a hallmark of cellular senescence. The modulation of SASP by senomorphic drugs, potentially can suppress the pro-inflammatory secretome of senescent cells, irrespective of the underlying senescence mechanism. In this study we tested a senomorphic drug, ruxolitinib, a Janus kinase inhibitor (JAKi), during acute and chronic radiotherapy related effects on the bone. Our clinical data indicate an early increase in several pro-inflammatory SASP proteins following radiotherapy of spinal metastasis in prostate cancer patients. Longitudinal assessment of SASP-related genes confirmed this acute elevation in several SASP markers in systemic circulation following irradiation of mouse femurs. In a proof-of-concept study, following two preclinical radiotherapy regimens of cumulative doses of 30Gy (5 x 6Gy) and 60Gy (5 x 12Gy), a senomorphic approach of JAKi treatment was more effective in alleviating radiation-related bone loss compared to the senolytic cocktail of D+Q. Early and intermittent suppression of SASP using JAK inhibitors alleviated chronic bone deterioration, diminished telomere dysfunction, lowered senescence and SASP marker expression, reduced bone-marrow adiposity, and mitigated radiation related lymphatic impairment. Overall, our study shows that early targeting of SASP proteins could be a potential therapeutic to prevent radiotherapy-related chronic bone loss and risk of fractures. Lay Summary Radiotherapy as part of cancer treatment is correlated with an acute increase in senescent cells. Here we show that the pro-inflammatory senescence associated secretory phenotype (SASP) becomes much more prominent soon after radiotherapy in both patients and mice. Suppression of the SASP using a Janus kinase inhibitor, ruxolitinib, reduced the overall senescent cell burden, improved bone architecture by promoting bone formation, reduced bone marrow adiposity, and mitigated radiation-induced lymphatic impairment. Overall, these findings suggest that early inhibition of the SASP may help mitigate several bone anomalies and prevent long-term bone loss and fractures after radiotherapy. Graphical Abstract

Abstract Background OpenEvidence answers clinical questions using retrieval augmented generation on curated sources with explicit citations. The company reports that over 40% of U.S. physicians (~ 400,000) consult it daily. Although several studies have evaluated the platform, the evidence base remains heterogeneous. Objective To systematically review studies evaluating OpenEvidence for clinical question answering and decision support. Methods A systematic search of MEDLINE/PubMed, Scopus, Web of Science, and Google Scholar was conducted from database inception to January 2026. Peer-reviewed studies evaluating OpenEvidence in clinical or clinically simulated contexts were included. Study selection, data extraction, and risk-of-bias assessment were performed independently by two reviewers in accordance with PRISMA guidelines. Results Eleven studies published between 2024 and 2026 were included in the analysis. OpenEvidence was evaluated as the primary platform in eight studies and as a comparator in three. OpenEvidence demonstrated the ability to generate evidence-supported responses and avoided fabricated citations. Performance was strongest in structured, guideline-based contexts. However, accuracy varied in complex clinical scenarios, and the platform often reinforced rather than altered clinical decisions. Limitations included dependence on the available retrieval context, interpretive errors despite accurate citations, variability across clinical domains, and the fact that OpenEvidence is a continuously updated system, limiting the generalizability and cross‑study comparability of point‑in‑time evaluations. Conclusions The rapid adoption of OpenEvidence among clinicians outpaces the sparse research available. With just 11 studies, limited in scope or confined to niche clinical domains, the evidence is still thin relative to its purported usage in daily medical practice. Adoption of such platforms demands prospective real-world studies with clinical endpoints and ongoing benchmarking.

Background The primary objective of this analysis was to assess the association between non-invasive biomarker results within the first 2-years post-kidney transplant and 10-year All Cause Graft Loss (ACGL). Methods CTOT-08 was linked with the Scientific Registry of Transplant Recipients (SRTR) to assess 10-year ACGL. Cox Regression was used to determine the association between gene expression profile (GEP) and donor-derived cell-free DNA (dd-cfDNA) results and ACGL. A Cox Regression with time-varying covariates was used to test associations with ACGL with simultaneous and repeated biomarker results. Results The final landmarked Cox model included clinical acute rejection (aHR 2.58 (1,30,5.13) for 1 rejection, aHR 3.41 (1.07,10.85) for 2 rejections), diabetes (aHR 1.71 (0.99,2.96)), recipient age (aHR 1.02 (1.00,1.04)), the highest quartile of positive GEP (aHR 2.44 (1.45,4.10)) and the highest quartile of positive dd-cfDNA (aHR 2.91 (1.77,4.78)). In the time-varying model, having both biomarkers positive at the same time carried the greatest association with ACGL (aHR 4.29 (2.10,8.76)). Conclusions In this multicenter, prospective analysis of GEP and dd-cfDNA on patient and graft outcomes, an independent association with long-term ACGL was demonstrated. Further, a time-varying analysis demonstrated that two biomarkers with independent methodologies tested at the same time can provide more information than either one alone.

Rationale: Neuromuscular blocking agents (NMBAs) show potential benefits on mortality and other complications of acute respiratory distress syndrome (ARDS) in adult patients. Evidence-based decisions and processes ensure appropriate use of neuromuscular blockade in adult patients with ARDS. Objectives: The objective of these guidelines was to develop evidence-based recommendations for the administration of NMBAs in critically ill adult patients with ARDS. Design: The American College of Critical Care Medicine Board convened a 21-member multidisciplinary panel of experts in critical care medicine, nursing, respiratory therapy, pharmacology, surgery, neurology, and anesthesiology. The panel included two expert methodologists specialized in developing evidence-based recommendations in alignment with the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. Conflict-of-interest policies were strictly followed during all phases of guidelines development including task force selection and voting. Methods: The panel members identified and formulated five Population, Intervention, Comparison, and Outcome questions. We conducted a systematic review for each question to identify the best available evidence, statistically analyzed the evidence, and assessed the certainty of the evidence using the GRADE methodology. We used the GRADE evidence-to-decision framework to formulate the recommendations. Results: The panel generated two conditional recommendations. One recommendation is to use NMBAs in adults with ARDS with Pa o 2 /F io 2 less than 150. For the other recommendations, there was equipoise in the recommendation for and against using titratable vs. fixed-dose NMBA dosing, a monitoring-based strategy for assessing depth of sedation and analgesia in adults with ARDS before initiating or while receiving neuromuscular blockade, and administration of NMBAs for patients who are proned, due to overall lack of evidence in critically ill patients and due to considerations of patient safety and experience concerns. Conclusions: These guidelines provide additional perspectives on the use of NMBA in patients with ARDS, recognizing that institutional and patient-specific considerations must help to guide the decision-making process.

ABSTRACT Lytic phages are a promising consideration to combat recalcitrant bacterial infections. To advance the possibility of using phage therapy in the clinical routine, standardized phage susceptibility testing methods are needed. Here, staphylococcal phage K was tested against 154 periprosthetic joint infection-associated Staphylococcus aureus isolates using a double overlay spot assay in technical and biological triplicates. Individual plaques were assessed using a morphology scoring system ranging from 0 (no plaques) to 4 (large, clear plaques), with scores ≥2 considered indicative of infectivity. Overall, 107 isolates exhibited scores ≥2. The intra-day and inter-day coefficients of variation were 0.9 and 2.5, respectively. Plaque-forming unit per milliliter (PFU/mL) titers correlated with morphology scores (Spearman’s ρ = 0.8, P < 0.0001). The results suggest high precision of the described spot assay assessing S. aureus susceptibility to phage K. IMPORTANCE Standardized laboratory assays for assessing phage susceptibility are a prerequisite for clinical implementation of phage therapy. No assay has been denoted a reference standard. Criteria that can be used to assess assay precision and suitability for routine testing are intermediate precision and repeatability. Here, staphylococcal phage K was tested using the double overlay spot assay against 154 periprosthetic joint infection-associated Staphylococcus aureus isolates in technical and biological triplicates. In addition to measuring phage titers, plaque-forming units were assessed with a scoring system. Results indicate high intermediate precision and repeatability of the method described.

Background Antitumor immune responses induced by oncolytic immunotherapy (OI) are often followed by upregulation of programmed death-ligand 1 (PD-L1). As such, the combination of OI with blockade of the programmed cell death protein-1 (PD-1)/PD-L1 axis has demonstrated therapeutic activity in preclinical and clinical trials. The purpose of this study is to understand further the immune-mediated mechanism of interaction between oncolytic viruses and anti-PD-1 therapy. Methods Tumor cells and immune cells (splenocytes) were cultured separately, or in co-culture with vusolimogene oderparepvec, an oncolytic herpes simplex virus expressing the fusogenic gibbon-ape leukemia virus-fusogenic membrane glycoprotein protein (GALV) and granulocyte-macrophage colony-stimulating factor (GM-CSF), also known as RP1. Viral replication, interferon (IFN) responses and PD-L1 expression were analyzed using wild-type, IFNAR1, TNFAR1 and STING knockout splenocytes. In vivo studies evaluated immune cell infiltrates into the tumor following RP1 administration with anti-PD-1 therapy. Results RP1 replication was evident in tumor cells but not splenocytes. This was also accompanied by upregulated IFN expression in cultured splenocytes that was absent in cultured tumor cells. However, when these cell types were co-cultured, splenocytes mediated an interferon response to RP1 via STING that was transmitted to tumor cells in a non-touch-dependent manner. Tumor cells responded to these input signals via upregulation of cell surface major histocompatibility complex-I and PD-L1 through tumor intrinsic JAK-STAT signaling. In vivo, an IFN signature was observed following intratumoral injection of RP1, both in injected and non-injected tumors, which was further increased when combined with anti-PD-1 therapy. Marked upregulation of PD-L1 was observed in tumors injected with RP1 accompanied by the recruitment of CD11b+Ly6G+neutrophils into the tumor microenvironment, which stained positive for PD-L1. Conclusion Overall, the data demonstrate that RP1 remodels the tumor microenvironment through a combination of direct and indirect effects on both tumor and immune cells, resulting in an overall more inflamed phenotype.

Abstract Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbidity, yet modifiable environmental risk factors remain poorly characterized. Prior studies typically have only examined a limited number of exposures and have rarely distinguished HDP subtypes (ie, gestational hypertension, preeclampsia, eclampsia, and chronic hypertension with or without superimposed preeclampsia) or accounted for residential mobility during pregnancy. To address these gaps, we conducted a spatial and contextual exposome study of HDP using linked electronic health records (EHR) and vital statistics data in Florida. We analyzed 686 412 singleton pregnancies conceived between 2013 and 2018, using computable phenotyping to distinguish HDP subtypes. A total of 245 spatial and contextual exposome measures spanning natural, built, and social environments were linked to residential histories from conception through gestational week 19. Using a two-phase double machine learning (DML) framework with exposure-specific, directed acyclic graph-guided confounder adjustment, we conducted discovery and replication analyses, followed by multi-treatment DML to estimate effect sizes. In Phase 1, 26 exposome measures replicated for gestational hypertension and 34 for overall HDP. In Phase 2, 12 measures remained associated with gestational hypertension and 11 with overall HDP, including air toxicants, meteorological factors, ultraviolet radiation, neighborhood crime indicators, environmental noise, and proximity to coastline. No exposures passed multiple-comparison thresholds for preeclampsia or eclampsia. These findings demonstrate that the spatial and contextual exposome contributes to HDP in a subtype-specific manner. Integrating EHR-linked phenotyping, residential mobility, and causal machine-learning methods offers a scalable framework for identifying environmental factors relevant to HDP prevention.
