Abstract	Background: Evidence regarding long-term postoperative follow-up of chronic rhinosinusitis with nasal polyps (CRSwNP) patients is scarce in the literature. The objective of the present study was to report long-term 12-year postoperative outcomes for CRSwNP patients. Methods: CRSwNP patients were prospectively followed after endoscopic sinus surgery. Sinonasal symptoms, nasal polyp score (NPS), Barcelona Smell Test 24 (BAST-24), Lund-Mackay Score (LMS), and Medical Outcome Study Short Form-36 (SF-36) questionnaire were assessed before and 12 years after surgery. Results: At long-term follow-up (median, 12 years), a strong improvement was noted for all patients (N=76) in nasal symptoms score, NPS, BAST-24, and LMS scores compared with baseline. No long-term improvement in SF-36 was found. Conclusion: Patients with CRSwNP have a long-term 12-year postoperative improvement in nasal symptoms, polyp size, computed tomography, and olfaction.

Abstract	An important pathogen of concern for Pacific oyster growers in the USA is ostreid herpesvirus 1 (OsHV-1). Currently, oyster stocks exist that are tolerant to OsHV-1; however, it is uncertain if a trade-off exists between their tolerance to OsHV-1 and their growth in different environments. To investigate any potential trade-offs, Pacific oyster families with varying levels of OsHV-1 tolerance were grown in a bay where OsHV-1 is endemic (Tomales Bay, CA) and in a bay where OsHV-1 is absent (Willapa Bay, WA). In Tomales Bay, we found that oysters from OsHV-1 tolerant families grew faster than oysters from OsHV-1 susceptible families, while in Willapa Bay, no statistically significant difference in growth was found between oyster families with different levels of OsHV-1 tolerance observed in Tomales Bay. These findings indicate that Pacific oysters bred to be tolerant to OsHV-1 would not be expected to have a longer time-to-market regardless of the presence of OsHV-1 in the growing environment.

Abstract	Two different perspectives have informed efforts to explain the link between the brain and behaviour. One approach seeks to identify neural circuit elements that carry out specific functions, emphasizing connectivity between neurons as a substrate for neural computations. Another approach centres on neural manifolds - low-dimensional representations of behavioural signals in neural population activity - and suggests that neural computations are realized by emergent dynamics. Although manifolds reveal an interpretable structure in heterogeneous neuronal activity, finding the corresponding structure in connectivity remains a challenge. We highlight examples in which establishing the correspondence between low-dimensional activity and connectivity has been possible, unifying the neural manifold and circuit perspectives. This relationship is conspicuous in systems in which the geometry of neural responses mirrors their spatial layout in the brain, such as the fly navigational system. Furthermore, we describe evidence that, in systems in which neural responses are heterogeneous, the circuit comprises interactions between activity patterns on the manifold via low-rank connectivity. We suggest that unifying the manifold and circuit approaches is important if we are to be able to causally test theories about the neural computations that underlie behaviour.

Abstract	Background: Septoplasty is one of the most frequently performed surgeries. However, there remains a question as to the effect of such intervention on the sense of smell. This study aims to examine the available evidence regarding the effect of septoplasty on the sense of smell. Methods: A database search was performed using PubMed, ScienceDirect, Google Scholar and The Cochrane Library databases from January 1990 to February 2020. Search terms included smell, olfaction, odor, septum, septoplasty, and septorhinoplasty. A meta-analysis was performed with 12 studies that provided sufficient data on change in olfaction. Results: 14 studies met the inclusion criteria, and 2 additional studies were included manually; comprising a total of 996 patients and 25 controls. Significant improvement in olfactory test scores was observed in all tests. Pre- and postoperative differences in means were 0.63 for BSIT, 0.80 for CCCRC test, 1.16 for odor threshold, 1.43 for odor discrimination, and 1.18 for odor identification. Conclusions: Septoplasty seems to improve olfactory function. However, the outcome of this intervention is discrete and not equal for all patients, so further randomized trials are needed to confirm current findings.

Abstract	Everyday challenges impact our ability to hear and comprehend spoken language with ease, such as accented speech (source factors), spectral degradation (transmission factors), complex or unfamiliar language use (message factors), and predictability (context factors). Auditory degradation and linguistic complexity in the brain and behavior have been well investigated, and several computational models have emerged. The work here provides a novel test of the hypotheses that listening effort is partially reliant on higher cognitive auditory attention and working memory mechanisms in the frontal lobe, and partially reliant on hierarchical linguistic computation in the brain's left hemisphere. We specifically hypothesize that these models are robust and can be applied in ecologically relevant and coarse-grain contexts that rigorously control for acoustic and linguistic listening challenges. Using functional near-infrared spectroscopy during an auditory plausibility judgment task, we show the hierarchical cortical organization for listening effort in the frontal and left temporal-parietal brain regions. In response to increasing levels of cognitive demand, we found (i) poorer comprehension, (ii) slower reaction times, (iii) increasing levels of perceived mental effort, (iv) increasing levels of brain activity in the prefrontal cortex, (v) hierarchical modulation of core language processing regions that reflect increasingly higher-order auditory-linguistic processing, and (vi) a correlation between participants' mental effort ratings and their performance on the task. Our results demonstrate that listening effort is partly reliant on higher cognitive auditory attention and working memory mechanisms in the frontal lobe and partly reliant on hierarchical linguistic computation in the brain's left hemisphere. Further, listening effort is driven by a voluntary, motivation-based attention system for which our results validate the use of a single-item post-task questionnaire for measuring perceived levels of mental effort and predicting listening performance. We anticipate our study to be a starting point for more sophisticated models of listening effort and even cognitive neuroplasticity in hearing aid and cochlear implant users.

Abstract	Background: Patients with septal deviation and/or turbinal hypertrophy may experience olfactory disfunction (OD). The aim of this study was to analyse the effect of septoplasty and/or turbinoplasty on both lateralized and bilateral olfactory function. Methodology: Prospective study of 47 patients with nasal obstruction secondary to septal deviation and/or turbinal hypertrophy and 20 healthy controls. The Barcelona Olfactory test (BOT-8), a new supraliminal orthonasal subjective olfactometry, was applied 3 times in a row (in each nostril separately and in both simultaneously). The 8 items were applied randomly to minimize the possible risk of learning. The test has not established the minimal clinically important difference (MCID). Anterior rhinomanometry and acoustic rhinometry were performed. All participants self-assessed smell loss and nasal obstruction using a visual analogue scale (VAS) and completed questionnaires for nasal obstruction (Nasal Obstruction Symptom Evaluation, NOSE) and for quality of life (QoL), using disease-specific (SinoNasal Outcome Test-22, SNOT-22) and generic (Short Form-12 Health Survey, SF-12) questionnaires. Nasal measurements and questionnaires were performed preoperatively and 12 months after surgery. Results: Before surgery, patients reported worse VAS on smell loss and on nasal obstruction compared to controls. Patients scored lower BOT-8 than controls. Lateralized preoperative olfactory function showed that all BOT-8 characteristics were lower at the narrow side than the wider one. Smell function and QoL improved significantly one year after surgery. Conclusions: Nasal septal deviation and turbinal hypertrophy lead to an olfactory impairment on the obstructed nostril. Nasal surgery provides a positive outcome on olfactory function, as well as on subjective and objective outcomes.
