The nasal microbiome is increasingly recognized for its role in asthma development, but inconsistent results small sample sizes have limited a clear understanding. We aimed to clarify the microbiome's using large datasets meta-transcriptomic analysis.

Asthma is considered severe if it remains uncontrolled despite optimal conventional therapy, characterised by poor symptom control, frequent exacerbations and increased exposure to systemic corticosteroids. This has a significant impact on morbidity, mortality healthcare resource utilisation. Recent advances in the understanding of asthma heterogeneity immunopathogenesis have helped delineate precise disease pathways. The discovery these pivotal pathways led development highly effective biologic therapies. Currently available biologics target immunoglobulin E, interleukin (IL)-5/IL-5Rα, IL-4Rα thymic stromal lymphopoietin. Identification specific phenotypes, utilising easily measurable biomarkers, paved way towards personalised precision management. Biologic therapies play role reducing exacerbations, hospitalisations need for maintenance steroids, while also improving quality life patients with asthma. evidence their clinical efficacy comes from randomised controlled trials (RCTs), extension studies, metanalyses real-world data. review synthesises findings early, RCTs subsequent studies following approval safety data completed variety settings, provide practical perspectives application enhance generalisability.

Pediatric asthma is the most common chronic childhood disease in US and a major public health concern. It considered to comprise multiple clinical variants or phenotypes with different etiologies pathophysiologies. Former research has shown that airway bacteriomes vary composition structure across pediatric phenotypes, but their functional diversity bacterial interactions have hardly been investigated. A previous study of 163 children from Washington DC identified three statistically each unique nasopharyngeal diversity. Here, I reanalyze 16S rRNA high-throughput sequences same cohort characterize metabolism interactions. detect 61 102 metabolic pathways (PICRUSt2; q ≤ 0.05) differentially expressed phenotypes. Most those are related biosynthesis degradation processes (p 0.0012) separated groups. Co-occurrence networks also differ connectivity suggesting group. Five eight keystone taxa detected Insights this studies, hence, confirm bacteriome heterogeneity asthma, increasing our understanding its etiology pathophysiology, provide new taxonomic biomarkers for targeted interventions therapies.

ABSTRACT Trichosanthes kirilowii is a plant used in traditional Chinese medicine. Its fruits, seeds, and roots can all be medicinally. The fruit of T. has moistening effect on the lung for arresting cough. However, there no scientific research to prove that improve asthma. Herein, we evaluated whether extract (TK) could reduce airway inflammation hyperresponsiveness (AHR) murine model Female BALB/c mice were sensitized with ovalbumin induce asthma treated varying oral doses TK from days 14 27 experiment. Additionally, IL‐4/TNF‐α‐stimulated BEAS‐2B cells different investigate inflammatory cytokine chemokine secretion. treatment significantly mitigated AHR, eosinophil infiltration, lungs asthmatic mice. It also alleviated goblet cell hyperplasia ROS levels while modulating Th2‐associated bronchoalveolar lavage fluid. Moreover, effectively proinflammatory cytokine, chemokine, eotaxin IL‐4 TNF‐α‐stimulated cells. Our results indicate improved symptoms through suppressed Th2‐cell activation, which inflammation, oxidative stress, AHR.

Asthma affects up to 10% of pregnancies and confers risk both mother child. Adverse maternal outcomes associated with asthma include preeclampsia, preterm labor, increased cesarean delivery. Maternal also increases risks low birth weight small-for-gestational-age weight, as well pediatric respiratory disease, including neonatal distress early-onset asthma. Despite these risks, evidence suggests that chronic acute exacerbations remain undertreated in pregnancy. Recent landmark clinical trials nonpregnant individuals have shown that, even for patients mild using as-needed inhaled corticosteroids combined long-acting bronchodilators rescue therapy dramatically reduces exacerbations. Inhaled are considered safe pregnancy effective reducing symptoms, preventing exacerbations, mitigating some adverse outcomes. Therefore, should be included a mainstay the treatment regimens all pregnant women asthma, preferably an corticosteroid rapid-onset bronchodilator combination inhaler use daily maintenance those more persistent symptoms or factors complications. Clinicians actively discourage discontinuation de-escalation therapies during educate on safety importance medications themselves their offspring. confer additional risk, so they must promptly recognized treated systemic bronchodilators.

Mitochondria are essential organelles within cells, playing various roles in numerous cellular processes, including differentiation, growth, apoptosis, energy conversion, metabolism, and immunity. The phenotypic variation of mitochondria is specific to different tissues cell types, resulting significant differences their function, morphology, molecular characteristics. Asthma a chronic, complex, heterogeneous airway disease influenced by external factors such as environmental pollutants allergen exposure, well internal at the tissue, cellular, genetic levels, lung structural immune granulocytes, mast cells. Therefore, comprehensive understanding responses stimuli changes crucial for elucidating pathogenesis asthma. Previous research on mitochondrial-targeted therapy asthma has primarily focused antioxidants. Consequently, it necessary summarize multifaceted discover additional strategies targeting this context. In review, our goal describe mitochondrial function response exposure across types other relevant context asthma, utilizing new terminology framework that encompasses cell-dependent characteristics, features, activity, behavior.
