Risk messaging style and its effect on public preparedness for earthquakes: longitudinal intervention-based study.

This study examines the effect of risk communication styles (fear-based versus empowerment-based) on households' earthquake preparedness. An online longitudinal study with intervention and control groups was conducted using a representative sample of the adult population in Israel. The change in the reported level of preparedness was assessed through Repeated Measures ANOVA with interaction effects for both the risk communication style and gender.

Bronchoalveolar lavage cytokine-based risk stratification of clinically-stable lung transplant recipients with undefined rejection: Further insights from a follow-up investigation.

Background: Surveillance bronchoscopies with bronchoalveolar lavage (BAL) and transbronchial biopsies (TBB) are primarily used to detect acute cellular rejection (ACR) or infection in lung transplant (LTx) recipients. We previously identified a BAL protein signature associated with chronic lung allograft dysfunction (CLAD) or death/retransplant in patients with stable minimal (grade A1) ACR. This present study aimed to determine whether similar BAL biomarkers predict outcomes in stable patients when ACR grade is undetermined.

Real-World and Patient-Reported Outcomes of Dupilumab and Other Biological Drugs for Chronic Obstructive Pulmonary Disease-A Systematic Review.

Background: Over the last few decades, the efficacy of biological therapies for COPD has been evaluated by different randomized controlled trials (RCTs). Still, the evaluation of real-world data and patient-reported outcome measures (PROMs) have not been performed in this field before. In the current work, we present a systematic literature review of the real-world data and PROMs of biological treatments for COPD.

[Pediatric coeliac disease: Clinical features and diagnostic process].

Celiac disease is a chronic condition that affects approximately 1% of the world's population, becoming a public health problem. The numerous publications and international guides published in recent years make it necessary to update aspects related to its diagnosis. Highly sensitive and specific serological determinations have allowed the identification of the clinical polymorphism.

Murine astrovirus (MuAstV) infection in mouse facilities in Brazil: First South American report.

Fragment-Based Interrogation of the 14-3-3/TAZ Protein-Protein Interaction.

The identification of chemical starting points for the development of molecular glues is challenging. Here, we employed fragment screening and identified an allosteric stabilizer of the complex between 14-3-3 and a TAZ-derived peptide. The fragment binds preferentially to the 14-3-3/TAZ peptide complex and shows moderate stabilization in differential scanning fluorimetry and microscale thermophoresis.

CYYR1 promotes the degradation of the E3 ubiquitin ligase WWP1 and is associated with favorable prognosis in breast cancer.

Ubiquitination plays a crucial role in cellular homeostasis by regulating the degradation, localization, and activity of proteins, ensuring proper cell function and balance. Among E3 ubiquitin ligases, WW domain-containing protein 1 (WWP1) is implicated in cell proliferation, survival, and apoptosis. Notably WWP1 is frequently amplified in breast cancer and associated with poor prognosis.

Comparison of galactomannan lateral flow assay and enzyme immunoassay to identify Aspergillus spp. in bronchoalveolar lavage fluid.

Aspergillus species can colonize and infect immunocompetent and immunocompromised hosts. Conventional fungal identification depends on microscopic analysis and microorganism medium growth. Other diagnostic methods, non-growth dependent, to invasive fungal infections, are the biomarkers that detect circulating polysaccharides, for example, 1-3-β-d-Glucan and galactomannan.

Microbial community-scale metabolic modelling predicts personalized short-chain fatty acid production profiles in the human gut.

Microbially derived short-chain fatty acids (SCFAs) in the human gut are tightly coupled to host metabolism, immune regulation and integrity of the intestinal epithelium. However, the production of SCFAs can vary widely between individuals consuming the same diet, with lower levels often associated with disease. A systems-scale mechanistic understanding of this heterogeneity is lacking.

Advanced Monitoring of HS Injection through the Coupling of Reactive Transport Models and Geophysical Responses.

Hydrogen sulfide (HS), an environmentally harmful pollutant, is a byproduct of geothermal energy production. To reduce the HS emissions, HS-charged water is injected into the basaltic subsurface, where it mineralizes to iron sulfides. Here, we couple geophysical induced polarization (IP) measurements in HS injection wells and geochemical reactive transport models (RTM) to monitor the HS storage efforts in the subsurface of Nesjavellir, one of Iceland's most productive geothermal fields.

The CD8 T cell content of transbronchial biopsies from patients with a first episode of clinically stable grade A1 cellular rejection is associated with future chronic lung allograft dysfunction.

Background: T cells drive acute cellular rejection (ACR) and its progression to chronic lung allograft dysfunction (CLAD) following lung transplantation. International Society for Heart and Lung Transplantation grade A1 ACR without associated allograft dysfunction is often untreated, yet some patients develop progressive graft dysfunction. T-cell composition of A1 ACR lesions may have prognostic value; therefore, protein-level and epigenetic techniques were applied to transbronchial biopsy tissue to determine whether differential T-cell infiltration in recipients experiencing a first episode of stable grade A1 ACR (StA1R) is associated with early CLAD.

Impact of Hurricanes, Tropical Storms, and Coastal Extratropical Storms on Indoor Air VOC Concentrations.

Understanding vapor intrusion (VI) temporal variability is key for the design of sampling strategies intended to assess reasonable maximum exposure of indoor air concentrations of volatile organic compounds (VOCs) as well as risk evaluation and mitigation planning. VI temporal variability has previously been shown to be dependent on the complex interactions of multiple independent variables-meteorological, hydrogeological, and human behavioral. Several meteorological variables, including barometric pressure, wind speed, and rainfall, are linked during tropical and extratropical storm events.

Neoantigen-specific stimulation of tumor-infiltrating lymphocytes enables effective TCR isolation and expansion while preserving stem-like memory phenotypes.

Background: Tumor-infiltrating lymphocytes (TILs) targeting neoantigens can effectively treat a selected set of metastatic solid cancers. However, harnessing TILs for cancer treatments remains challenging because neoantigen-reactive T cells are often rare and exhausted, and ex vivo expansion can further reduce their frequencies. This complicates the identification of neoantigen-reactive T-cell receptors (TCRs) and the development of TIL products with high reactivity for patient treatment.
