    Abstract In this edition of Rhinology we feature the work of Connell and colleagues from Australia on chronic rhinosinusitis that describes an interesting new pipeline to characterize the bacterial composition of microbiota. We are constantly exposed to a multitude of micro-organisms in the environment and our immune system has the important task discerning and fighting off potential threats. In most people the immune system is doing its job properly and prevents anything untoward from happening. On occasion, a microbe slips by the first (innate) level of defense and we might suffer from an infection. This then activates the second layer of (the adaptive) defense tasked to clear this infection. Sometimes the immune system gets its wrong and starts a full-out defense against something harmless, and an allergy is born. The task of the immune system of doing what is right is even more difficult than it might seem at first sight. In addition to these incidental potential threats, our mucosal surfaces are lined with commensal bacteria which contributes to the complexity of our environment. This collection of bacteria or microbiome has become a major focus of research, as the composition of this microbiome seems related to the health state of the individual. Originally the relationship between the gut microbiome and the development of asthma and allergy was the main focus. In recent years, the focus has been broadened to include the microbiome of the upper and lower airways. In addition to allergy, our field has also been given more and more attention to studying the microbiome in chronic rhinosinusitis.

    Abstract Cystic fibrosis is caused by genetic defects that impair the CFTR channel in airway epithelial cells. These defects may be overcome by specific CFTR modulating drugs, for which the efficacy can be predicted in a personalized manner using 3D nasal-brushing-derived airway organoids in a forskolin-induced swelling assay. Despite of this, previously described CFTR function assays in 3D airway organoids were not fully optimal, because of inefficient organoid differentiation and limited scalability. In this report, we therefore describe an alternative method of culturing nasal-brushing-derived airway organoids, which are created from an equally differentiated airway epithelial monolayer of a 2D air-liquid interface culture. In addition, we have defined organoid culture conditions, with the growth factor/cytokine combination neuregulin-1β and interleukin-1β, which enabled consistent detection of CFTR modulator responses in nasal-airway organoid cultures from subjects with cystic fibrosis.

    Abstract This work describes for the first time the fabrication and characterization of multicomponent interpenetrating networks composed of collagen I, hyaluronic acid, and poly(ethylene glycol) diacrylate for the 3D culture of human neural stem cells, astrocytes, and microglia. The chemical composition of the scaffolds can be modulated while maintaining values of complex moduli within the range of the mechanical performance of brain tissue (∼6.9 kPa) and having cell viability exceeding 84%. The developed scaffolds are a promising new family of biomaterials that can potentially serve as 3D

    Abstract The nasal cavity displays immune tolerance to commensal bacteria under homeostatic conditions, which is rapidly converted to a pro-inflammatory response upon infection. Yet, the factors that control this conversion are still largely unknown. Here, we provide evidence that Fc gamma receptor III (FcγRIII) stimulation breaks immune tolerance to bacteria in the human nasal cavity through activation of nasal epithelial cells, which are the first line of defense against invading microbes. While under steady-state conditions human nasal epithelial cells were completely non-responsive to Gram-negative bacteria P. aeruginosa or TLR4 ligand LPS, IgG opsonization of bacteria, as occurs upon infection, strongly induced production of pro-inflammatory agents such as IL-6 and IL-8. This breaking of tolerance to bacteria was completely dependent on FcγRIII, which amplified cytokine gene transcription through cross-talk with TLR4. In addition, we identified that epithelial cells from patients suffering from chronic rhinosinusitis with nasal polyps do not display LPS tolerance, thereby providing an explanation for the disturbed host defense responses of these patients. Taken together, these data are the first to identify FcγR expression on nasal epithelial cells, as well as to identify its important role in controlling the balance between tolerance and inflammation in the nasal cavity.

    Abstract Background: In contrast to the well-known significant impairment of quality of life (QoL) in allergic rhinitis (AR), the degree of impairment in QoL in nonallergic rhinitis (NAR) remained unknown for a long time, due to a lack of a validated questionnaire to assess QoL in the NAR patient group. In this study, a validation of the mini-RQLQ questionnaire in NAR patients was performed, followed by an assessment of QoL in NAR patients compared to AR and healthy controls. Secondly, use of medication and treatment satisfaction in AR and NAR was assessed.
    Methods: The study was an observational cohort study in 287 AR and 160 NAR patients. Patients with symptoms of rhinitis were recruited from a tertiary care outpatient clinic of the Otorhinolaryngology Department. Allergic rhinitis (AR) was defined as one or more positive results on skin prick testing and clinically relevant symptoms of rhinitis related to their sensitization. Nonallergic rhinitis (NAR) was defined as clinically relevant symptoms of rhinitis but without positive results on skin prick testing. The mini-RQLQ was successfully validated in this study for NAR patients.
    Results: Quality of life (QoL) in NAR patients was equally-and for some aspects even more-impaired compared to AR. More than half of both AR and NAR patients were unsatisfied with treatment.
    Conclusion: These results demonstrate a significant impairment in both AR and NAR patients in their QoL combined with a low treatment satisfaction, emphasizing the need for adequate treatment, especially in the NAR patient group.

    Abstract Abstract Domestic cats Felis catus have a complex and contentious history. They fill multiple societal roles (e.g. as pest controllers and companion animals), which has led to a variety of animal welfare, conservation, and human health concerns. Popular press articles play an important role in how people learn about key issues surrounding cats, but they may present some issues more frequently than other issues. We conducted a global media content analysis of 796 articles in the English‐language media from 1990 to 2018 on issues related to free‐roaming cats, such as their environmental impacts, the threats and welfare issues cats face, and how they are managed. We aimed to determine whether non‐experts learning about the issues around free‐roaming cats exclusively from the popular press would be exposed to multiple stakeholder views or opinions. Over 95% of articles analysed were from North America. Most of the people interviewed in the popular press were from non‐governmental organizations, mainly from cat welfare or cat rights groups (which are often focused on only one side of the issue). Researchers, shelter organizations, veterinarians, and groups that have different opinions than cat rights or welfare organizations on how to resolve issues surrounding free‐roaming cats were rarely interviewed by the popular press. Most articles focused on cat welfare issues and the management strategies of euthanasia or trap–neuter–release (TNR), whereas less than one‐third of the articles acknowledged that cats have any impact on wildlife or the broader environment. We found that the popular press often presented an oversimplified picture of issues related to free‐roaming cats and provided unbalanced coverage. We also show evidence of framing by the popular press, including mainly presenting the viewpoints and perspectives from animal welfare and rights groups, focusing on TNR or euthanasia as the only viable cat management strategies when many alternatives exist and often have greater support from experts, and discussing ...
