BackgroundAllergic rhinitis (AR) and rhinosinusitis (RS) negatively impact psychological well-being and health-related quality of life (HRQoL). However, few population-based studies have investigated the effects of these conditions on mental health and HRQoL.PurposeTo explore independent associations of AR and/or RS with mental health and HRQoL using data from the 2013–2015 Korea National Health and Nutrition Examination Survey (KNHANES).MethodsThe KNHANES is a nationwide cross-sectional survey of the non-institutionalized population of Korea. A total of 15,441 adults completed the clinical examination and the health questionnaire. We divided all participants into four groups: AR-/RS-, AR-/RS+, AR+/RS-, and AR+/RS+. Logistic regression analyses were performed after adjustment for sociodemographic characteristics, general health behaviors, and other comorbidities.ResultsThe AR+/RS+ group contained the highest proportion of subjects with perceived stress and depressed mood. Subjects with AR+/RS+ also had more frequent problems in terms of pain/discomfort and anxiety/depression. After adjusting for all confounders, the odds ratios (ORs) were 2.96 (p = 0.009) for depressed mood and 3.17 (p = 0.013) for suicidal ideation in the AR+/RS+ group compared with in the AR-/RS- group. The AR+/RS- group reported more perceived stress (OR, 1.56, p = 0.003) and depression (OR, 1.72, p = 0.024) compared with the AR-/RS- group. In terms of the ORs for HRQoL, the AR+/RS+ group reported more problems in terms of self-care (OR, 3.73, p = 0.038) and more pain/discomfort (OR 2.19, p = 0.006) compared with the AR-/RS- group.ConclusionsIn the Korean population, AR and RS exerted a synergistic negative impact on mental health and HRQoL, especially suicidal ideation. Most patients seek help from clinicians for impaired HRQoL. Therefore, clinicians should consider the underlying mental health and HRQoL of patients with AR and/or RS, as these may be impaired by their conditions.

The total perforation closure rate after FGM was 87% (40 cases), with no statistical difference among perforation size groups, even though the mean closure rates of the 10-20% and >30% perforation groups were lower than other groups. The difference in the closure rates of patients with anteriorly located perforations and those with perforations in other sites was not significant. The mean postoperative air-bone gap (ABG) was 14.3 (±7.5) dB. Mean postoperative ABG improved significantly after FGM; however, on a per-group basis, the >30% perforation group had the poorest results and the difference was statistically significant. The difference in mean postoperative ABGs of the two groups depending on the location of the perforation (anterior and other) was not significant.

Background Several studies have reported the benefits of olfactory training (OT) in the olfactory nervous system of mouse models. Therefore, in this study we performed next‐generation sequencing to evaluate the effects of OT on mRNA sequencing in the olfactory area. Methods Mice in each group were administered 300 mg of 3‐methylindole per kilogram of mouse weight. The olfactory function was evaluated by a food‐finding test once a week. The olfactory neuroepithelium was harvested for histologic examination and protein analysis. Subsequently, data analysis, gene ontology and pathway analysis, quantitative real‐time polymerase chain reaction of mRNA, and Western blot analysis were conducted. Results Mice were divided into 4 groups according to treatment. Control, anosmia, training, and steroid group mice resumed food finding. Olfactory Maker Protein, olfr1507, ADCY3, and GNAL mRNA expression was higher in the olfactory neuroepithelium of OT than anosmia group mice. In total, 26,364 mRNAs were analyzed. Comparison of the results of OT vs anosmia revealed that ADCY8,10, GFAP, NGF, NGFR, GFAP, and BDNF mRNAs were upregulated in the gene ontology. Conclusion OT improved olfactory function, as indicated by the food‐finding test. OT improved the olfactory recovery time to stimulate olfactory nerve regeneration. OT may initially stimulate the olfactory receptor, followed by neurogenesis. Steroid therapy and OT operated under completely different mechanisms in the upregulated gene study. These results indicate that OT may be one of the future modalities for treating olfactory impairment.
