ABSTRACT

A hypertonic solution of Ibuprofen (Ibu) was designed to nebulize, associating a low concentration of Ibu with L-Arginine (AR), to increase solubility and serve as a nitric oxide donor. To provide preclinical research human bronchial epithelial cells derived from a cystic fibrosis patient homozygous for the ΔF508 CFTR mutation (CFBE41o-) and mouse RAW 264.7 macrophages were pre-treated with Ibu (10-100 μM), AR (20 and 200 μM), or the combination Ibu-AR (10-100 μM). After Angiotensin II (AngII) or LPS/Interferon ϒ (IFN) stimulation, Reactive Oxygen Species (ROS) generation, Nitric Oxide (NO) formation, and the expression of inflammatory markers were determined. Ibu-AR (10/20 μM) significantly reduced ROS generation stimulated by AngII (p < 0.01) in CFBE41o- cells preserved the NO pathway and inhibited LPS-stimulated nitrite generation (p < 0.001). In macrophages, the combination Ibu-Ar, in a ratio of 1:2-1:6, efficiently scavenged excessive ROS generated by LPS, and significantly induced NO generation (p < 0.001), but inhibited nitrite formation. In LPS/IFNϒ-activated Raw, gene signature of M1polarization including tumor necrosis factor (TNF-α), NADPH Oxidase 2 (NOX-2), MCP-1, and inducible nitric oxide synthase (iNOS) were significantly downregulated by Ibu-AR, as well TNF-α, IL-6, and iNOS protein expressions. The inhibitory effect produced by Ibu-AR on M1 macrophages was associated with the inhibition of p-ERK1/2 and p-STAT3. Ibu-AR represents an effective therapeutic strategy for reducing oxidative stress, preserving NO bioavailability, and modulating inflammation in chronic inflammatory diseases.

ABSTRACT

AIM: This study aimed to assess the relationship between sleep quality, malnutrition risk, and nutritional status in adolescents with cystic fibrosis(CF).

MATERIAL AND METHOD: This cross-sectional study was conducted with 55 adolescents (aged 10-18 years) diagnosed with CF. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), and malnutrition risk was evaluated based on disease-specific criteria. Nutritional status was assessed using body mass index (BMI), BMI percentiles, dietary energy intake, and food group consumption. Multiple linear regression analyses were used to determine the relationship between sleep quality, malnutrition risk, and nutritional status.

RESULTS: Among the participants, 50.9 % had poor sleep quality, and 29.1 % were classified as high-risk for malnutrition. Poor sleep quality was significantly associated with increased malnutrition risk (p < 0.05), independent of dietary energy intake and BMI percentiles. Lower BMI percentile was strongly associated with higher malnutrition risk (p < 0.001), identifying BMI as a critical predictor. Specifically, 27.3 % of participants had a BMI <10th percentile, which contributed to their classification as high-risk for malnutrition. However, dietary energy intake did not significantly predict malnutrition risk despite its relevance in dietary management.

CONCLUSION: This study emphasizes the crucial role of sleep quality in assessing malnutrition risk among adolescents with CF. Poor sleep quality was associated with higher malnutrition risk, suggesting that sleep disturbances may contribute to nutritional challenges. Sleep quality should be considered a key factor in assessing malnutrition risk among adolescents with CF and integrated into clinical practice to develop comprehensive management strategies addressing sleep disturbances and nutritional challenges, improving health outcomes.

ABSTRACT

INTRODUCTION: People with idiopathic pulmonary fibrosis (IPF) and other forms of progressive pulmonary fibrosis (PPF) have a high symptom burden and a poor health-related quality of life (HRQoL). Despite efforts to offer specialised treatment, clinical care for these patients remains suboptimal and several nonmedical needs remain unaddressed. Developing a core outcome set (COS) can help to identify a minimum set of agreed-upon outcomes that should be measured and acted-upon in clinical care.

AIM: As a first step towards developing a COS for IPF/PPF, we aimed to identify outcome domains investigated in IPF/PPF research.

METHODS: Conducted within the COCOS-IPF (Co-designing a Core Outcome Set for and with patients with IPF) project, this scoping review follows Joanna Briggs Institute methodology and PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines to search PubMed, Embase and Web of Science for quantitative, qualitative and mixed-methods papers. We extracted each paper's outcomes verbatim and classified them using the COMET (Core Outcome Measures in Effectiveness Trials) taxonomy. Then, the research team structured outcomes or concepts with similar meanings inductively into outcome domains.

RESULTS: We included 428 papers, extracting 1685 outcomes. Most outcomes (n=1340) were identified in quantitative sources, which we could classify in 64 outcome domains, with the main domains being "all-cause survival" (n=237), "lung function" (n=164) and "exercise capacity" (n=99). Qualitative sources identified 51 outcome domains, with the most frequent being "capability to do activities you enjoy" (n=31), "anxiety, worry and fear" (n=26) and "dealing with disease progression" (n=25).

CONCLUSIONS: The identified outcomes, spanning diverse domains, highlight the complexity of patient experiences and can form the basis to develop a COS for IPF/PPF clinical care, as well as future research.

ABSTRACT

A woman in her mid-70s presented with worsening dyspnoea, cough and fatigue initially treated for pneumonia. Despite antibiotics, her condition deteriorated, prompting further investigation. Medical history included previous breast implants, the latter of which had ruptured years earlier and was subsequently removed prior to the current presentation. Imaging revealed bilateral lung consolidations and lymphadenopathy. Bronchoalveolar lavage indicated macrophagic alveolitis, while biopsies showed chronic inflammation and the presence of silicone. Diagnosis of chronic pulmonary silicone embolism was made, a rare condition linked to the migration of silicone particles into the lungs, causing inflammation. Treatment involved corticosteroids, leading to symptom resolution. This case highlights the diagnostic challenges of silicone pneumonitis, which can manifest years after implant rupture and removal. Clinicians should be aware of this condition to avoid misdiagnosis and delayed treatment, as symptoms may persist even after implant removal due to irreversible lung fibrosis.

ABSTRACT

Patients with interstitial lung disease (ILD) and especially with idiopathic pulmonary fibrosis(IPF) suffer from reduced survival expectation and risk of exacerbations. Lung cancer is a relevant comorbidity in ILD patients and associated with impaired survival.The most frequent ILD among patients with NSCLC (Non-small cell lung cancer) is idiopathic pulmonary fibrosis (IPF), which is associated with an greater decline in lung function and a higher risk of death.The prevalence of lung cancer in patients with ILD is up to 10% and in autopsy studies a prevalence up to 48% has been found.There are no guidelines for patients with lung cancer and ILD. Moreover, no adequate evidence is available.Therefore, we reviewed currently available literature to present an overview of the state of the art.In this review we focus on staging and treatment of the comorbidity of lung cancer and ILD.

ABSTRACT

While the rise of antibiotic resistance poses a global health challenge, the development of new antibiotics has slowed down over the past decades. This turned the attention of researchers towards the rational design of drug combination therapies to combat antibiotic resistance. In this review we discuss how drug combinations can exploit the deleterious pleiotropic effects of antibiotic resistance and conclude that each drug interaction has its prospective therapeutic application.

ABSTRACT

Rubisco is the primary CO2-fixing enzyme of the biosphere1, yet it has slow kinetics2. The roles of evolution and chemical mechanism in constraining its biochemical function remain debated3,4. Engineering efforts aimed at adjusting the biochemical parameters of rubisco have largely failed5, although recent results indicate that the functional potential of rubisco has a wider scope than previously known6. Here we developed a massively parallel assay, using an engineered Escherichia coli7 in which enzyme activity is coupled to growth, to systematically map the sequence-function landscape of rubisco. Composite assay of more than 99% of single-amino acid mutants versus CO2 concentration enabled inference of enzyme velocity and apparent CO2 affinity parameters for thousands of substitutions. This approach identified many highly conserved positions that tolerate mutation and rare mutations that improve CO2 affinity. These data indicate that non-trivial biochemical changes are readily accessible and that the functional distance between rubiscos from diverse organisms can be traversed, laying the groundwork for further enzyme engineering efforts.

ABSTRACT

The assessment of research performance is widely seen as a vital tool in upholding the highest standards of quality, with selection and competition believed to drive progress. Academic institutions need to take critical decisions on hiring and promotion, while facing external pressure by also being subject to research assessment1-4. Here we present an outlook on research assessment for career progression with specific focus on promotion to full professorship, based on 314 policies from 190 academic institutions and 218 policies from 58 government agencies, covering 32 countries in the Global North and 89 countries in the Global South. We investigated how frequently various promotion criteria are mentioned and carried out a statistical analysis to infer commonalities and differences across policies. Although quantitative methods of assessment remain popular, in agreement with what is found in more geographically restricted studies5-9, they are not omnipresent. We find differences between the Global North and the Global South as well as between institutional and national policies, but less so between disciplines. A preference for bibliometric indicators is more marked in upper-middle-income countries. Although we see some variation, many promotion policies are based on the assumption of specific career paths that become normative rather than embracing diversity. In turn, this restricts opportunities for researchers. These results challenge current practice and have strategic implications for researchers, research managers and national governments.

ABSTRACT

Vibrio parahaemolyticus poses a notable threat to marine ecosystems and can cause infections and disease outbreaks in seafood species, which can affect humans upon consumption. The global impacts of such infections and outbreaks on human and animal health led to a growing number of studies from various countries discussing the prevention, control, treatment, and overall implications of V. parahaemolyticus. Hence, this study aims to retrieve relevant studies on V. parahaemolyticus using a bibliometric analysis to understand current research status, trends, and hotspots regarding this bacteria. Relevant literature was searched across the Scopus database, and the data were subsequently analyzed using Biblioshiny software. In addition, a manual examination was conducted to identify the hosts of V. parahaemolyticus and diseases caused by the bacteria. Overall, 7,096 records were obtained from Scopus from 1963 to 2023. A bibliometric analysis identified 17,220 authors, with China emerging as the global leader. The analysis also highlighted significant keywords such as "Vibrio parahaemolyticus," "Litopenaeus vannamei," and "innate immunity," suggesting a focus on the impact of V. parahaemolyticus on L. vannamei, specifically emphasizing the shrimp's innate immune responses. Host-disease interaction network also uncovered 53 interactions between hosts and diseases involving L. vannamei or Penaeus vannamei as the primary host, with acute hepatopancreas necrosis disease (AHPND) emerging as the most prevalent among them. This study can enhance our understanding of infections caused by V. parahaemolyticus and contribute to the development of effective strategies for their prevention and management.

ABSTRACT

Colonies of the social bacterium Myxococcus xanthus go through a morphological transition from a thin colony of cells to three-dimensional droplet-like fruiting bodies as a strategy to survive starvation. The biological pathways that control the decision to form a fruiting body have been studied extensively. However, the mechanical events that trigger the creation of multiple cell layers and give rise to droplet formation remain poorly understood. By measuring cell orientation, velocity, polarity, and force with cell-scale resolution, we reveal a stochastic local polar order in addition to the more obvious nematic order. Average cell velocity and active force at topological defects agree with predictions from active nematic theory, but their fluctuations are substantially larger than the mean due to polar active forces generated by the self-propelled rod-shaped cells. We find that M. xanthus cells adjust their reversal frequency to tune the magnitude of this local polar order, which in turn controls the mechanical stresses and triggers layer formation in the colonies.

ABSTRACT

Rats (Rattus norvegicus) have been widely utilized as model animals due to their physiological characteristics, making them suitable for surgical and long-term studies. They have played a crucial role in biomedical research, complementing studies conducted in mice. The advent of genome editing technologies has facilitated the generation of genetically modified rat strains, advancing studies in experimental animals. Among these innovations, Cre-driver rat models have emerged as powerful tools for spatiotemporal control of gene expression. However, their development and characterization remain less advanced compared to mouse models. In this study, we developed liver-targeting Cre knock-in rats and reporter knock-in rats to evaluate Cre recombinase expression profiles in different genetic contexts. Our results revealed that insertion orientation and promoter origin significantly influence Cre expression patterns. Notably, forward insertion of the Albumin (Alb) promoter-driven Cre sequence at the ROSA26 locus resulted in ubiquitous Cre expression, while reverse insertion confined Cre expression predominantly to the liver. Interestingly, Cre expression under an endogenous Alb promoter unexpectedly induced expression in non-liver tissues, which may suggest a potential link to the in vivo dynamics of albumin. These findings underscore the importance of rigorous characterization in Cre-based transgenic systems. By elucidating the roles of promoter origin, insertion site, and orientation, our study provides valuable insights for optimizing Cre-driver rat models. These findings pave the way for refining genetic strategies to enhance tissue specificity and reliability in functional genomics and disease modeling.

ABSTRACT

Tumor microenvironment (TME) has become a major focus of cancer research as a promising therapeutic target. TME comprises cancer cells surrounded by nonmalignant cells, vessels, lymphoid organs, immune cells, nerves, intercellular components, molecules and metabolites located within or near the tumor lesion. Neuromedin U (NMU), a secretory peptide identified in the TME, has gained much attention as an important player in cancer and nonmalignant cell crosstalk. NMU receptors were detected in cancer cells as well as in nonmalignant TME components, such as immune, stromal and endothelial cells. We propose here to discuss the concept that NMU secreted by cancer cells activates cellular components of TME and thus contributes to the formation of microenvironment that favors tumor growth and cancer progression. We summarized the available data on cancer tissues and cell types that have been identified as a source of NMU and/or receptor-expressing NMU targets. We made a critical selection of NMU-receptor positive cell types that are known components of the TME of most malignant tumors. Finally, we discussed whether NMUs and NMU receptors represent a potential therapeutic target for cancer treatment, and summarized information on the tools available to modulate their activity.

ABSTRACT

PURPOSE: The p.G12C mutation in KRAS is commonly found in many cancers and was previously untreatable until drugs like sotorasib were developed. However, up to 15% of patients treated with sotorasib have experienced hepatobiliary adverse events. To investigate whether these side effects are more common among sotorasib users, a pharmacovigilance study is necessary.

METHODS: This study used the FDA adverse event reporting system (FAERS) database, a publicly available repository of reported drug adverse events, and AERSMine, an open-access pharmacovigilance tool, to investigate these adverse events.

RESULTS: A total of 428 hepatobiliary adverse events were linked to sotorasib. Hepatic cytolysis had the highest reported relative risk at 26.541 and a safety signal of 4.726. Elevated liver and biliary enzymes such as AST, ALT, ALP, and GGT were commonly observed, but with lower reported relative risk and safety signal values, which supports previous real-world reports.

CONCLUSIONS: These findings highlight the hepatobiliary risks associated with sotorasib and underscore the importance of closely monitoring liver function in patients who are using the medication. This is particularly crucial for patients with hepatobiliary cancers, as disease progression and adverse events could be misinterpreted.

ABSTRACT

BACKGROUND: Amiodarone is a widely used antiarrhythmic agent with significant toxicities and drug interactions more likely to affect older adults. Nevertheless, data regarding amiodarone safety in this population are limited.

METHODS: We conducted a retrospective analysis of FDA Adverse Event Reporting System (FAERS) data from 2003 to 2024 . Reports with amiodarone as the primary suspect were compared to other antiarrhythmics (sotalol, dronedarone, flecainide, propafenone, dofetilide). Disproportionality analysis assessed reporting odds ratios (RORs) for predefined adverse events in adults (<75 years) and older adults (≥75 years). Interaction analysis evaluated differences between age groups.

RESULTS: Among 9,196 amiodarone FAERS reports, 4,129 (44.9%) involved older adults. Hyperthyroidism (ROR 39.1, 95% CI [25-61] and ROR of 23.4 [11-49.8]) and hypothyroidism (ROR 36.9 [15.2-89.8] and ROR 24.5 [11.5-52.1]) were substantially over-reported in amiodarone users among both adults and older adults, respectively. Drug-induced liver injury and peripheral neuropathy were also over-reported without a significant age interaction. Interstitial lung disease was reported more frequently in amiodarone users overall, with significantly higher reporting in older adults (ROR 11.4 [6.9-18.6] vs. 4.9 [3.4-7.0], Pinteraction=0.007). Bradycardia was also over-reported in older adults compared to adults (ROR 1.6 [1.3-2] vs. 1.0 [0.8-1.3], Pinteraction=0.003). Torsades de Pointes/QT prolongation were less frequently reported in both age groups.

CONCLUSIONS: In this global postmarketing study, interstitial lung disease and bradycardia were more frequently reported in older adults treated with amiodarone. These findings support vigilant monitoring for these adverse events, particularly in older patients.

ABSTRACT

INTRODUCTION: . Idiosyncratic adverse drug reactions (IADRs) or drug hypersensitivity reactions (DHRs) represent a major health problem because they are unpredictable and can be severe with potential life-long or even lethal consequences. Their pathophysiology is not clear but thought to be immune mediated supported by the significant statistical association of these reactions with specific alleles of the human leukocyte antigen (HLA) gene.

AREA COVERED: This comprehensive update review summarizes the currently available evidence on the role of HLA gene locus in IADRs and discusses the present understanding of the pathophysiology of IADRs. We searched the available literature in PubMed and Google Scholar with no date restriction for publications on HLA and adverse drug reactions. Findings are summarized and discussed in the context of the currently available evidence.

EXPERT OPINION: The role of the immune system in IADRs and the role of pharmacogenetic testing in this field is evident. HLA genetic testing is a very promising in the management of these reaction. Many obstacles seem to prevent pharmacogenetic testing to meet its full potential including cost and healthcare providers education. Further work in needed to provide more evidence and allow widespread use of pharmacogenetic testing in the clinical practice.

ABSTRACT

In patients with cystic fibrosis (CF), repeated cycles of infection and inflammation eventually lead to fatal lung damage. Although diminished mucus clearance can be restored by highly effective CFTR modulator therapy, inflammation and infection often persist. To elucidate the role of the innate immune system in CF etiology, we investigated a CF pig model and compared these results with those for preschool children with CF. In newborn CF pigs, we observed changes in lung immune cell composition before the onset of infection that were dominated by increased monocyte infiltration, whereas neutrophil numbers remained constant. Flow cytometric and transcriptomic profiling revealed that the infiltrating myeloid cells displayed a more immature status. Cells with comparably immature transcriptomic profiles were enriched in the blood of CF pigs at birth as well as in preschool children with CF. This pattern coincided with decreased CD16 expression in the myeloid cells of both pigs and humans, which translated into lower phagocytic activity and reduced production of reactive oxygen species in both species. These results were indicative of a congenital, translationally conserved, and functionally relevant aberration of the immune system in CF. In newborn wild-type pigs, CFTR transcription in immune cells, including lung-derived and circulating monocytes, isolated from the bone marrow, thymus, spleen, and blood was below the detection limits of highly sensitive assays, suggesting an indirect etiology of the observed effects. Our findings highlight the need for additional immunological treatments to target innate immune deficits in patients with CF.

ABSTRACT

The field of artificial intelligence (AI) has entered a new cycle of intense opportunity, fueled by advances in deep learning, including generative AI. Applications of recent advances affect many aspects of everyday life, yet nowhere is it more important to use this technology safely, effectively, and equitably than in health and health care. Here, as part of the National Academy of Medicine's Vital Directions for Health and Health Care: Priorities for 2025 initiative, which is designed to provide guidance on pressing health care issues for the incoming presidential administration, we describe the steps needed to achieve these goals. We focus on four strategic areas: ensuring safe, effective, and trustworthy use of AI; promotion and development of an AI-competent health care workforce; investing in AI research to support the science, practice, and delivery of health and health care; and promotion of policies and procedures to clarify AI liability and responsibilities.
