In addition to complying with strict academic standards, nursing students must acquire relevant knowledge and skills, and learn how to carry themselves in different and often stressful professional settings. These obligations could severely affect their mental health. The purpose of this study was to examine the mental health status of undergraduate nursing students and related factors. A total of 1368 nursing students from different universities in Spain and Chile were included in this study, which took place over the 2018–2019 academic year. We assessed their levels of stress related to specific learning methodologies and determined their mental health status using the General Health Questionnaire (GHQ-28). The results revealed that the more advanced the course was, the lower the total GHQ-28 score. The stress generated by different types of training activities had a significant effect on the total GHQ-28 score. These results suggest that nursing education could act as a protective factor against mental health disorders. Although a heavy academic workload could lead to higher levels of stress, overall, it seems that mental health is better in more advanced courses than in initial academic years.

Autoantibodies neutralizing type I interferons (IFN-Is; IFNα or IFNω) exacerbate severe viral disease, but specific treatments are unavailable. With footprint profiling, we delineate two dominant IFN-I faces commonly recognized by neutralizing IFN-I autoantibody–containing plasmas from aged individuals with HIV-1 and from individuals with severe COVID-19. These faces overlap with IFN-I regions independently essential for engaging the IFNAR1/IFNAR2 heterodimer, and neutralizing plasmas efficiently block the interaction of IFN-I with both receptor subunits in vitro. In contrast, non-neutralizing autoantibody–containing plasmas limit the interaction of IFN-I with only one receptor subunit and display relatively low IFN-I–binding avidities, thus likely hindering neutralizing function. Iterative engineering of signaling-inert mutant IFN-Is (simIFN-Is) retaining dominant autoantibody targets created potent decoys that prevent IFN-I neutralization by autoantibody-containing plasmas and that restore IFN-I–mediated antiviral activity. Additionally, microparticle-coupled simIFN-Is were effective at depleting IFN-I autoantibodies from plasmas, leaving antiviral antibodies unaffected. Our study reveals mechanisms of action for IFN-I autoantibodies and demonstrates a proof-of-concept strategy to alleviate pathogenic effects.

Aging is associated with increased breast cancer risk, and the oldest and youngest patients have worse outcomes, irrespective of subtype. It is unknown how age affects cells in the breast tumor microenvironment or how they contribute to age-related pathology. Here we discover age-associated differences in cell states in human estrogen receptor-positive and triple-negative breast cancers using analyses of existing bulk and single-cell transcriptomic data. We generate and apply an Age-Specific Program ENrichment (ASPEN) analysis pipeline, revealing age-related changes, including increased tumor cell epithelial–mesenchymal transition and cancer-associated fibroblast inflammatory responses in triple-negative breast cancer. Estrogen receptor-positive breast cancer displays increased ESR1 expression and reduced vascular and immune cell metabolism with age. Cell interactome analysis reveals candidate signaling pathways that drive age-related cell states. Spatial analyses across independent clinical cohorts support the computational findings. This work identifies potential targets for age-adapted therapeutic interventions for breast cancer.

New reperfusion therapies have improved the clinical recovery rates of acute ischemic stroke patients (AISP), but it is not known whether other factors, such as the ability to cope, might also have an effect. The aim of this study was to evaluate the effect of endovascular treatment (EVT) on coping strategies, quality of life, and neurological and functional outcomes in AISP at 3 months and 1 year post-stroke. A multicenter, prospective, longitudinal, and comparative study of a sub-study of the participants in the Endovascular Revascularization with Solitaire Device versus Best Medical Therapy in Anterior Circulation Stroke within 8 Hours (REVASCAT) clinical trial was conducted after recruiting from two stroke centers in Catalonia, Spain. The cohort consisted of 82 ischemic stroke patients (n = 42 undergoing EVT and n = 40 undergoing standard best medical treatment (BMT) as a control group), enrolled between 2013–2015. We assessed the coping strategies using the Brief Coping Questionnaire (Brief-COPE-28), the health-related quality of life (HRQoL) with the EQ-5D questionnaire, and the neurological and functional status using the National Institute of Health Stroke Scale (NIHSS), Barthel Index (BI), modified Rankin Scale (mRS), and Stroke Impact Scale-16 (SIS-16). Bivariate analyses and multivariate linear regression models were used. EVT patients were the ones that showed better neurological and functional outcomes, and more patients presented reporting no pain/discomfort at 3 months; paradoxically, problem-focused coping strategies were found to be significantly higher in patients treated with BMT at 1 year.

With a high risk of relapse and death, and a poor or absent response to therapeutics, the triple-negative breast cancer (TNBC) subtype is particularly challenging, especially in patients who cannot achieve a pathological complete response (pCR) after neoadjuvant chemotherapy (NAC). Although the tumor microenvironment (TME) is known to influence disease progression and the effectiveness of therapeutics, its predictive and prognostic potential remains uncertain. This work aimed to define the residual TME profile after NAC of a retrospective cohort with 96 TNBC patients by immunohistochemical staining (cell markers) and chromogenic in situ hybridization (genetic markers). Kaplan–Meier curves were used to estimate the influence of the selected TME markers on five-year overall survival (OS) and relapse-free survival (RFS) probabilities. The risks of each variable being associated with relapse and death were determined through univariate and multivariate Cox analyses. We describe a unique tumor-infiltrating immune profile with high levels of lymphocytes (CD4, FOXP3) and dendritic cells (CD21, CD1a and CD83) that are valuable prognostic factors in post-NAC TNBC patients. Our study also demonstrates the value of considering not only cellular but also genetic TME markers such as MUC-1 and CXCL13 in routine clinical diagnosis to refine prognosis modelling.

Triple-negative breast cancer (TNBC) is particularly challenging due to the weak or absent response to therapeutics and its poor prognosis. The effectiveness of neoadjuvant chemotherapy (NAC) response is strongly influenced by changes in elements of the tumor microenvironment (TME). This work aimed to characterize the residual TME composition in 96 TNBC patients using immunohistochemistry and in situ hybridization techniques and evaluate its prognostic implications for partial responders vs. non-responders. Compared with non-responders, partial responders containing higher levels of CD83+ mature dendritic cells, FOXP3+ regulatory T cells, and IL-15 expression but lower CD138+ cell concentration exhibited better OS and RFS. However, along with tumor diameter and positive nodal status at diagnosis, matrix metalloproteinase-9 (MMP-9) expression in the residual TME was identified as an independent factor associated with the impaired response to NAC. This study yields new insights into the key components of the residual tumor bed, such as MMP-9, which is strictly associated with the lack of a pathological response to NAC. This knowledge might help early identification of TNBC patients less likely to respond to NAC and allow the establishment of new therapeutic targets.
