Comparative safety of enoxaparin versus other low-molecular-weight heparins in cancer-associated venous thromboembolism : a real-world cohort study from RIETE
Full text linkPublisher Copyright: © 2025 The Author(s)Background: Low-molecular-weight heparins (LMWHs) are widely used in the treatment of cancer-associated venous thromboembolism (VTE), yet their long-term safety profiles remain insufficiently compared in clinical practice. Objectives: The primary outcome was major bleeding over a 6-month follow-up. Secondary outcomes included VTE recurrence, non-major clinically relevant bleeding, and all-cause mortality. Methods: We analyzed 7287 patients with active cancer and acute VTE from the RIETE registry (2009-2022) who were treated with full-dose enoxaparin (n = 5628) or tinzaparin/dalteparin (n = 1659). Analyses were adjusted using multivariable Cox models, Fine-Gray competing risk models, frailty models clustered by center, and propensity score approaches. Results: Major bleeding occurred in 3.84% of patients receiving enoxaparin versus 2.53% in the tinzaparin/dalteparin group (adjusted hazard ratio [aHR] 1.56; 95% CI: 1.11-2.19), with consistent findings across all sensitivity analyses. Enoxaparin was also associated with higher all-cause mortality (28.3% vs 25.1%; aHR 1.22; 95% CI: 1.09-1.37). No significant differences were observed in VTE recurrence (3.59% vs 3.07%) or non-major bleeding (3.98% vs 3.25%). Importantly, during the first 10 days of therapy, major bleeding occurred in 1.2% of patients treated with enoxaparin twice-daily, compared to 0.4% with once-daily dosing and 0.1% in the tinzaparin/dalteparin group (P < .001). Conclusion: In this large, observational study, enoxaparin, particularly in twice-daily regimens, was associated with significantly increased risks of bleeding and mortality compared to tinzaparin/dalteparin. These findings may help refine LMWH selection and dosing strategies in patients with cancer-associated VTE and warrant further investigation in prospective studies.Peer reviewe
¿INFLUYE EL CICLO MENSTRUAL EN EL RENDIMIENTO DEPORTIVO DE LAS JUGADORAS DE VOLEIBOL? UN ESTUDIO PILOTO
Full text linkPublisher Copyright: © 2025, Universidad Catolica San Antonio Murcia. All rights reserved.The menstrual cycle (MC) is a physiological concept that has had an exponential increase in the field of sports and research in recent years. In addition, it is a biological process corresponding to women and regulated by certain hormones that allow the possibility of fertility and may also affect other functional capacities of the female organism. Nevertheless, the related scientific literature is scarce. For this reason, the aim of the study was to perform research on female volleyball players, applying an educational methodology consisting of a talk and a workshop/focus group to discover the possible improvements in the analyzed variables. The sample consisted of eight female players (age = 20.5 ± 1.41 years; weight = 59.25 ± 7.59 kg; height = 168.75 ± 6.23 cm). A descriptive and association study was carried out between the study variables considering the time of data collection. The results highlight the importance of developing educational plans related to the MC in teams of female athletes because significant associations were found in the knowledge (question three and question six) and communication (question 14) sections. Finally, the results suggest the need to motivate and encourage the use of tools and education regarding to the MC both in sports and in the social sphere, to promote and improve knowledge, communication, and the perception of the influence of the MC. For this reason, it is recommended that sporting institutions to consider planning and developing informative talks before, during and after sports seasons.Peer reviewe
Maternal plasma cell-free RNA as a predictor of early and late-onset preeclampsia throughout pregnancy
Full text linkPublisher Copyright: © The Author(s) 2025.Early- and late-onset preeclampsia (EOPE and LOPE) pose serious maternal-fetal risks, yet non-invasive early prediction remains challenging. In a prospective cohort of 9,586 pregnancies, we analyze trimester-specific plasma cell-free RNA (cfRNA) profiles from 42 EOPE and 43 LOPE cases versus 131 normotensive controls. Organ-specific transcriptomic shifts distinguish EOPE from LOPE. Predictive models based on cfRNA signatures identify EOPE up to 18.0 weeks before clinical onset in the first-trimester (T1) (AUC = 0.88), and 8.5 weeks in the second trimester (T2) (AUC = 0.89). LOPE is predicted 14.9 weeks in advance using T2 data (AUC = 0.90), while T1 performance is lower (AUC = 0.68). External validation confirms robust EOPE prediction (AUC = 0.87 at T1; 0.81 at T2) and acceptable LOPE performance (AUC = 0.63 at T1; AUC = 0.77 at T2). EOPE models are enriched for decidual transcripts, suggesting early maternal involvement; LOPE models reflect broader tissue contributions. These findings offer a path to early, non-invasive, subtype-specific preeclampsia risk stratification and prevention.Peer reviewe

Immune Imprinting, Non-Durable Hybrid Immunity, and Hybrid Immune Damping Following SARS-CoV-2 Primary Vaccination with BNT162b2 and Boosting with mRNA-1273
Full text linkPublisher Copyright: © 2025 by the authors.Background/Objectives: Long-term studies on the immune response following multiple doses of SARS-CoV-2 mRNA vaccines remain limited. Methods: Secondary analyses of data from a cohort of non-immunocompromised subjects who received two doses of BNT162b2 (primary vaccination) and a booster with mRNA-1273 nine months later. Antibodies targeting the receptor-binding domain of the S1 subunit of the SARS-CoV-2 spike (anti-RBD) were measured at eight time points during follow-up; the SARS-CoV-2-specific T cell response was measured 16 and 25 months after primary vaccination using an interferon-γ release assay. Results: During the 9-month follow up period after primary vaccination and before the mRNA-1273 booster, anti-RBD were significantly higher at all time points in subjects with documented SARS-CoV-2 infection before the first study time point (previously infected subjects; n = 50) compared to naïve subjects (n = 208; p < 0.05). During a 16-month follow up period following the mRNA-1273 booster, anti-RBD were lower at all time points in previously infected subjects (n = 21) compared to naïve subjects (n = 109), although the differences were non-significant. Breakthrough SARS-CoV-2 infections increased over time in both groups, particularly after the mRNA-1273 booster. Most participants had a persistent SARS-CoV-2 specific T cell response regardless of prior infection. Conclusions: These findings suggest a modulating effect of previous SARS-CoV-2 infection on the humoral immune response to mRNA vaccination, a non-durable hybrid immunity following mRNA vaccination in previously infected subjects, and attenuation of the humoral immune response (immune damping) after repeated exposure to SARS-CoV-2 antigens through mRNA vaccination and/or infection.Peer reviewe

The JAK2 46/1 haplotype influences PD-L1 expression
No full textPublisher Copyright: © 2025 American Society of HematologyAlthough described more than a decade ago, the mechanism by which the JAK2 46/1 haplotype increases the risk of developing JAK2-mutated myeloproliferative neoplasms (MPNs) remains unexplained. Inflammation and immunity are linked to MPN development and thus could be relevant to the mechanism by which 46/1 mediates its effect. Here, we show that programmed death-1 receptor ligand (PD-L1) expression is elevated in 46/1 haplotype, both in healthy carriers and in CD34+ cells from patients with MPN. Using circular chromosome conformation capture, we observed that PD-L1 and the neighboring PD-L2 loci physically interact with JAK2 in a manner that differs between 46/1 and nonrisk haplotypes. CRISPR/Cas9 genome editing identified a region within JAK2 intron 2 that influences both JAK2 and PD-L1 expression. We suggest that increased PD-L1 expression may be relevant to the mechanism by which 46/1 leads to an increased inherited risk of developing MPN.Peer reviewe

Guiding first-line treatment decisions in advanced urothelial carcinoma : a global survey
Full text linkPublisher Copyright: © The Author(s) 2025. Published by Oxford University Press.Background: Enfortumab vedotin combined with pembrolizumab (EV-P) has become the new standard first-line therapy for patients with advanced urothelial carcinoma (aUC), based on its superior efficacy over platinum-based chemotherapy. As this regimen is increasingly adopted in routine care, treatment decisions may often occur in sites without dedicated genitourinary oncology expertise. This global survey aimed to explore how physicians perceive clinical factors that may influence the safe and effective use of EV-P in daily practice. Material and methods: A panel of international physicians with experience in treating patients with genitourinary cancers developed a 17-question survey addressing practice settings, experience in managing aUC, and clinical considerations relevant to the use of EV-P. The participants were recruited through a network-based convenience sampling method. The responses were descriptively analyzed. Results: A total of 201 genitourinary physicians from 32 countries completed the questionnaire. The most frequently cited potential absolute contraindications were sensory or motor neuropathy grade≥2 (64.2%), ECOG-PS≥3 (59.2%), and non–urothelial component >50% of the tissue sample (59.2%). Other notable concerns included severe corneal/retinal abnormalities, HbA1c >11%, severe skin comorbidities, liver impairment grade ≥2, and dialysis dependence. Conclusions and relevance: This survey provides practical insights into real-world physician perspectives on patient selection for EV-P. The findings highlight the need for guidance to support personalized risk assessment, facilitate early identification of patients who may require enhanced monitoring, and optimize safe integration of EV-P into clinical practice.Peer reviewe
Placental growth factor before 11 weeks for screening of preterm preeclampsia : The PreMoM study
Full text linkPublisher Copyright: © 2025 The Author(s). Acta Obstetricia et Gynecologica Scandinavica published by John Wiley & Sons Ltd on behalf of Nordic Federation of Societies of Obstetrics and Gynecology (NFOG).Introduction: Our objective was to compare the predictive performance of the Fetal Medicine Foundation (FMF) competing-risk model for preterm preeclampsia (PE) screening using placental growth factor (PlGF) measurements obtained at 11–13+6 weeks versus before 11 weeks of gestation. Material and Methods: This multicenter prospective cohort study included women with singleton pregnancies attending their routine first-trimester assessment (11+0 to 13+6 weeks) in four hospitals across Spain from 2021 to 2023. Maternal characteristics, biophysical parameters (mean arterial pressure and uterine artery pulsatility index), and biochemical markers (PlGF measured twice in each woman, before 11 weeks and between 11 and 13+6 weeks) were assessed. Risk assessment for preterm PE was estimated by the FMF algorithm. Predictive performance was evaluated by comparing detection rates (DR) at different fixed screen-positive rates (SPR), area under the receiver-operating characteristic curve (AUROC), and calibration plots. Statistical adjustments were made to account for prophylactic aspirin use. Results: The study population comprised 3448 women, including 19 (0.55%) who developed preterm preeclampsia and 47 (1.36%) who developed term preeclampsia. At 10% SPR, the detection rates (adjusted for aspirin use) were highest for the model incorporating PlGF between 11 and 13+6 weeks (72.9%; 95% CI, 42.2%–90.9%), compared to models with PlGF before 11 weeks (66.4%; 95% CI, 39.9%–85.4%) and without PlGF (66.0%; 95% CI, 39.3%–85.3%). Similar trends were observed at higher SPR thresholds. The best discrimination (AUROC: 0.863; 95% CI, 0.754–0.971) and calibration were also achieved by the model using PlGF between 11 and 13+6 weeks. Conclusions: PlGF measured before 11 weeks did not improve preterm PE screening performance. Due to the small number of cases, further validation is needed. Maternal and biophysical markers remain a viable alternative when PlGF is unavailable.Peer reviewe
