Outcomes of Immunotherapy Treatment in Sinonasal Mucosal Melanoma.

Background: Sinonasal mucosal melanoma has poor survival despite multimodality treatment. While the impact of immunotherapy (IT) on metastatic cutaneous melanoma is well-defined, there are relatively little data on sinonasal mucosal melanoma.

Objective: We sought to define immunotherapy outcomes in patients with sinonasal mucosal melanoma.

Correlation of the Sinonasal Outcome Test-22 With the University of Washington Quality of Life in Assessing Quality of Life in Sinonasal Malignancy Utilizing a Multicenter Prospective Observational Cohort Registry.

In this multi-center sinonasal malignancies (SNM) cohort, the Sino-nasal Outcome Test has a correlation with the University of Washington Quality of Life (UWQOL) for assessing QOL. The use of both instruments remains recommended to provide complete and complementary information. Future design of an easy-to-use tool specific to SNM is needed to encompass all aspects of QOL.

A prospective longitudinal study assessing the impact of rhinovirus and bacterial infections in acute exacerbations of chronic rhinosinusitis.

Background: Acute exacerbations of chronic rhinosinusitis (AECRS) are thought to arise from common viral infections progressing to secondary bacterial infections. However, the pathophysiology of AECRS remains poorly understood due to a lack of prospective longitudinal studies.

Methods: We conducted a one-year prospective longitudinal study involving chronic rhinosinusitis (CRS) adults.

University of Washington Quality of Life subdomain outcomes after treatment of sinonasal malignancy: A prospective, multicenter study.

Purpose: Sinonasal malignancies (SNMs) adversely impact patients' quality of life (QOL) and are frequently identified at an advanced stage. Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients.

SNOT-22 subdomain outcomes following treatment for sinonasal malignancy: A prospective, multicenter study.

Background: Patients with sinonasal malignancy (SNM) present with significant sinonasal quality of life (QOL) impairment. Global sinonasal QOL as measured by the 22-item Sinonasal Outcomes Test (SNOT-22) has been shown to improve with treatment. This study aims to characterize SNOT-22 subdomain outcomes in SNM.

Does Extended Reality Simulation Improve Surgical/Procedural Learning and Patient Outcomes When Compared With Standard Training Methods?: A Systematic Review.

Introduction: The use of extended reality (XR) technologies, including virtual, augmented, and mixed reality, has increased within surgical and procedural training programs. Few studies have assessed experiential learning- and patient-based outcomes using XR compared with standard training methods.

Methods: As a working group for the Society for Simulation in Healthcare, we used Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and a PICO strategy to perform a systematic review of 4238 articles to assess the effectiveness of XR technologies compared with standard training methods.

Predictive factors for decreased baseline quality of life in patients with sinonasal malignancies.

Background: The impact of sinonasal malignancies (SNMs) on quality of life (QOL) at presentation is poorly understood. The Sinonasal Outcome Test (SNOT-22) and University of Washington Quality of Life (UWQOL) are validated QOL instruments with distinctive subdomains. This study aims to identify factors impacting pretreatment QOL in SNM patients to personalize multidisciplinary management and counseling.

Viral infections and chronic rhinosinusitis.

Viral infections are the most common cause of upper respiratory infections; they frequently infect adults once or twice and children 6 to 8 times annually. In most cases, these infections are self-limiting and resolve. However, many patients with chronic rhinosinusitis (CRS) relay that their initiating event began with an upper respiratory infection that progressed in both symptom severity and duration.

Long-term quality of life after treatment in sinonasal malignancy: A prospective, multicenter study.

Background: Quality of life (QOL) for individuals with sinonasal malignancy (SNM) is significantly under-studied, yet it is critical for counseling and may impact treatment. In this study we evaluated how patient, treatment, and disease factors impact sinonasal-specific and generalized QOL using validated metrics in a large cohort over a 5-year posttreatment time frame.

Methods: Patients with SNM who underwent definitive treatment with curative intent were enrolled in a prospective, multisite, longitudinal observational study.

The Role of Viruses in the Inception of Chronic Rhinosinusitis.

Chronic rhinosinusitis (CRS) is a complex inflammatory disorder that affects between 2% and 16% of adults in the United States, with estimated healthcare costs between 4 and 12 million USD. Viruses are a common etiologic factor for URIs, are frequently identified in the sinuses of patients with CRS, and trigger CRS exacerbations. Therefore, investigating the role of viruses provides an opportunity to identify their role in the pathogenesis of CRS.

Epithelial cell responses to rhinovirus identify an early-life-onset asthma phenotype in adults.

Background: The study of pathogenic mechanisms in adult asthma is often marred by a lack of precise information about the natural history of the disease. Children who have persistent wheezing (PW) during the first 6 years of life and whose symptoms start before age 3 years (PW) are much more likely to have wheezing illnesses due to rhinovirus (RV) in infancy and to have asthma into adult life than are those who do not have PW (PW).

Objective: Our aim was to determine whether nasal epithelial cells from PW asthmatic adults as compared with cells from PW asthmatic adults show distinct biomechanistic processes activated by RV exposure.

The GSDMB rs7216389 SNP is associated with chronic rhinosinusitis in a multi-institutional cohort.

Background: Chronic rhinosinusitis (CRS) is a multifactorial disease with a high co-occurrence with asthma. In this multicohort study, we tested whether single nucleotide polymorphisms (SNPs) associated with childhood asthma and rhinovirus (RV)-associated disease are related to an increased susceptibility to adult CRS in a multicohort retrospective case-control study.

Methods: Participants at two tertiary academic rhinology centers, University of Arizona (UofA) and University of Pennsylvania (UPenn) were recruited.

Development of a self-directed sinonasal surgical anatomy video curriculum: Phase 1 validation.

Background: Sinusitis is a common outpatient diagnosis made by physicians and is a reason for referral to otolaryngologists. A foundation in basic sinonasal anatomy is critical in understanding sinus pathophysiology and avoiding complications. Our objective in this study was to develop and to validate a self-directed surgical anatomy video for medical students.

International consensus statement on allergy and rhinology: rhinosinusitis 2021.

Unlabelled: I.

Executive Summary: BACKGROUND: The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR-RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR-RS-2021 as well as updates to the original 140 topics.

MUC1 contributes to goblet cell metaplasia and MUC5AC expression in response to cigarette smoke in vivo.

Goblet cell metaplasia (GCM) and mucin overproduction are a hallmark of chronic rhinosinusitis (CRS) and chronic obstructive pulmonary disease (COPD). In the airways, cigarette smoke (CS) induces activation of the epidermal growth factor receptor (EGFR) leading to GCM and overexpression of the gel-forming mucin MUC5AC. Although previous studies have demonstrated that a membrane-bound mucin, MUC1, modulates the activation of CS-induced EGFR, the role of MUC1 in CS-induced GCM and mucin overproduction has not been explored.

High-Efficiency, Selection-free Gene Repair in Airway Stem Cells from Cystic Fibrosis Patients Rescues CFTR Function in Differentiated Epithelia.

Cystic fibrosis (CF) is a monogenic disorder caused by mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene. Mortality in CF patients is mostly due to respiratory sequelae. Challenges with gene delivery have limited attempts to treat CF using in vivo gene therapy, and low correction levels have hindered ex vivo gene therapy efforts.

Virtual coach: the next tool in functional endoscopic sinus surgery education.

Backgound: Functional endoscopic sinus surgery (FESS) can be challenging as novices become accustomed to handling endoscopes and instruments while navigating complex sinonasal anatomy. Experts demonstrate fluid and efficient motions when addressing pathology. The training process from novice to expert relies on hands-on experience in cadaveric laboratories and preceptorship models that require significant time and expense.

Are rhinoviruses implicated in the pathogenesis of sinusitis and chronic rhinosinusitis exacerbations? A comprehensive review.

Background: Rhinovirus (RV) infections are the most common cause of viral upper respiratory infections (URIs), and in the majority of persons they are self-limiting. However, in others, viral URIs can progress to bacterial sinusitis and induce chronic rhinosinusitis (CRS) exacerbations.

Methods: We conducted a comprehensive Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) review through April 2018 based on MEDLINE, EMBASE, Web of Science-Science Citation Index (SCI), and Conference Proceedings Citation Index- Science (CPCI-S) using keywords: RV, respiratory virus, sinusitis, and airway epithelial cells.
