Allergic Rhinitis Amplifies Asthma Risk in Patients With Chronic Rhinosinusitis: A Large‐Scale Retrospective Cohort Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and allergic rhinitis (AR) are two highly prevalent airway diseases in the United States. While the coexistence of CRS and asthma is well recognized, less is known about the development of new‐onset asthma in CRS, particularly in the context of comorbid AR. This study assessed the impact of CRS and AR on

Interspecies Biofilm Dynamics Among Staphylococci: Inflammatory Contributions to Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Introduction Staphylococcus species are frequently isolated from the sinonasal niche of chronic rhinosinusitis (CRS) patients. While Staphylococcus aureus is often associated with recalcitrant CRS, Staphylococcus epidermidis and Staphylococcus lugdunensis are largely deemed commensal.

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A

Angewandte Chemie, EarlyView.
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Fluorogenic Coupled Assays Reveal Catalytic Properties, Inhibition Constants and Cellular Location of Mucin‐Active Carbohydrate Sulfatases

Angewandte Chemie, EarlyView.
We report plate‐based coupled assays to rapidly and quantitatively determine the activity and selectivity of mucin‐active carbohydrate sulfatases. This fluorogenic assay further enables inhibitor identification and allows determination of (sub‐)cellular location. ABSTRACT Sulfated glycans play a central role in human health and influence cell signaling,

Leptin May Promote Eosinophilic CRSwNP Progression by Enhancing Eosinophil Chemotaxis and Angiogenesis Under a Type 2 Inflammatory Milieu

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyp (CRSwNP) is a heterogeneous Type 2 inflammatory disease characterized by enhanced eosinophilic infiltration. Both innate and adaptive immunity are involved in the onset and progression of CRSwNP.

Large‐Diameter DNA‐Scaffolded Nanopores Enabled by Loosely Packed Peptides for Single‐Molecule Sensing

Angewandte Chemie, EarlyView.
A nanopore composed of transmembrane peptides and a DNA scaffold that assists peptide assembly was constructed. By employing peptides containing the unnatural amino acid 2‐aminoisobutyric acid (Aib), which promotes loose packing between helices, a large‐diameter nanopore was achieved.

Complications and Clinical Outcomes Following Modified Endoscopic Denker's With Pyriform Aperture Preservation: A Prospective Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The modified endoscopic Denker's (MED) approach provides access to all maxillary sinus (MS) walls for resection of various MS and retromaxillary pathologies, but the anteromedial maxilla has historically been resected. This study determined complication rates and outcomes following MED with pyriform aperture (PA) preservation ...

Chronic alcohol consumption compromises gut barrier integrity and promotes endotoxemia: Implications for sepsis susceptibility in immunocompromised hosts

Animal Models and Experimental Medicine, EarlyView.
Chronic alcohol exposure disrupts intestinal barrier integrity, resulting in a leaky gut and enhanced translocation of lipopolysaccharide (LPS) and microbial products into the systemic circulation. Alcohol‐induced endotoxemia drives exaggerated pro‐inflammatory responses, mitochondrial damage, and activation of the cGAS–STING pathway, particularly in ...
