Acute rhinosinusitis is a common ailment accounting for millions of office visits annually, including that of Mrs D, a 51-year-old woman presenting with 5 days of upper respiratory illness and facial pain. Her case is used to review the diagnosis and treatment of acute rhinosinusitis. Acute viral rhinosinusitis can be difficult to distinguish from acute bacterial rhinosinusitis, especially during the first 10 days of symptoms. Evidence-based clinical practice guidelines developed to guide diagnosis and treatment of acute viral and bacterial rhinosinusitis recommend that the diagnosis of acute rhinosinusitis be based on the presence of "cardinal symptoms" of purulent rhinorrhea and either facial pressure or nasal obstruction of less than 4 weeks' duration. Antibiotic treatment generally can be withheld during the first 10 days of symptoms for mild to moderate cases, given the likelihood of acute viral rhinosinusitis or of spontaneously resolving acute bacterial rhinosinusitis. After 10 days, the likelihood of acute bacterial rhinosinusitis increases, and initiation of antibiotic therapy is supported by practice guidelines. Complications of sinusitis, though rare, can be serious and require early recognition and treatment. [ABSTRACT FROM AUTHOR]

Objective: In 1997, the Task Force on Rhinosinusitis (TFR) set forth symptom-based diagnostic guidelines for chronic rhinosinusitis (CRS). In the present study, we examined radiologic correlates of the TFR diagnostic criteria for rhinosinusitis.Study Design and Setting: One hundred twenty-five consecutive patients undergoing computed tomography (CT) scans of the sinuses were studied at Oregon Health and Science University. Patients were evaluated prospectively with a questionnaire based on the TFR criteria, and their CT scans were graded according to the Lund-Mackay scoring system.Results: Of the 125 patients, 115 met the symptom criteria for CRS. However, 40 of 115 had negative scans (Lund-McKay score, 0) despite meeting the diagnostic criteria for rhinosinusitis. Of 115, 75 had positive scans (Lund-McKay score, >1). Of the 10 patients who had negative diagnoses for rhinosinusitis, 9 had a positive CT scan. The Kappa coefficient was -0.103 (+/-95% confidence interval, -0.201 to -0.004), indicating poor agreement between CRS positivity and CT positivity. The sensitivity of TFR criteria for detecting a positive scan was 89%, but the specificity was poor at only 2%.Conclusion and Significance: Based on these pilot data, it appears that the specificity and predictive value of the current TFR criteria may not be adequate to serve as a diagnostic standard for rhinosinusitis. Additional validating data may provide guidance for improving the sensitivity and specificity of symptom-based diagnostic instruments for rhinosinusitis. [ABSTRACT FROM AUTHOR]

Objectives: The 22-question SinoNasal Outcome Test (SNOT-22) assesses chronic rhinosinusitis (CRS) severity. We aimed to identify predictors of SNOT-22 score improvement following highly effective modulator therapy (HEMT) initiation and to corroborate the SNOT-22 minimal clinically important difference (MCID) in adults with cystic fibrosis (CF)., Methods: Prospective observational data was pooled from four studies across 10 US centers investigating people with CF (PwCF) and CRS. Three studies evaluated HEMT's impact on CRS. For participants enrolled prior to HEMT initiation, SNOT-22 scores were obtained at baseline and after 3-6 months of HEMT. Multivariate regression identified predictors of improvement. Cronbach's alpha and four distribution-based methods were used to assess internal consistency and calculate the MCID of the SNOT-22., Results: A total of 184 PwCF participated with mean baseline SNOT-22 scores ranging from 18.1 to 56.7. Cronbach's alpha was ≥0.90 across sites. Participants at sites with pre- and post-HEMT data reported improvement in SNOT-22 scores after initiating HEMT (all p < 0.05). Worse baseline SNOT-22 score (odds ratio (OR): 1.05, p < 0.001, 95% CI: 1.02-1.08), F508del homozygosity (OR: 4.30, p = 0.040, 95% CI: 1.14-18.99), and absence of prior modulator therapy (OR: 4.99, p = 0.017, 95% CI: 1.39-20.11) were associated with greater SNOT-22 improvement. The mean MCID calculated via distribution-based methods was 8.5., Conclusion: Worse baseline sinonasal symptoms, F508del homozygosity, and absence of prior modulator therapy predicted greater improvement after HEMT initiation. The mean MCID for SNOT-22 in PwCF is 8.5 points, similar to non-CF individuals with CRS, and provides a threshold specifically for PwCF. The SNOT-22 has strong internal consistency in PwCF., Level of Evidence: 3 Laryngoscope, 134:3965-3973, 2024., (© 2024 The Authors.

Background: With the aging global population and the rising burden of Alzheimer disease and related dementias (ADRDs), there is a growing focus on identifying mild cognitive impairment (MCI) to enable timely interventions that could potentially slow down the onset of clinical dementia. The production of speech by an individual is a cognitively complex task that engages various cognitive domains. The ease of audio data collection highlights the potential cost-effectiveness and noninvasive nature of using human speech as a tool for cognitive assessment., Objective: This study aimed to construct a machine learning pipeline that incorporates speaker diarization, feature extraction, feature selection, and classification to identify a set of acoustic features derived from voice recordings that exhibit strong MCI detection capability., Methods: The study included 100 MCI cases and 100 cognitively normal controls matched for age, sex, and education from the Framingham Heart Study. Participants' spoken responses on neuropsychological tests were recorded, and the recorded audio was processed to identify segments of each participant's voice from recordings that included voices of both testers and participants. A comprehensive set of 6385 acoustic features was then extracted from these voice segments using OpenSMILE and Praat software. Subsequently, a random forest model was constructed to classify cognitive status using the features that exhibited significant differences between the MCI and cognitively normal groups. The MCI detection performance of various audio lengths was further examined., Results: An optimal subset of 29 features was identified that resulted in an area under the receiver operating characteristic curve of 0.87, with a 95% CI of 0.81-0.94. The most important acoustic feature for MCI classification was the number of filled pauses (importance score=0.09, P=3.10E-08). There was no substantial difference in the performance of the model trained on the acoustic features derived from different lengths of voice recordings., Conclusions: This study showcases the potential of monitoring changes to nonsemantic and acoustic features of speech as a way of early ADRD detection and motivates future opportunities for using human speech as a measure of brain health., (©Huitong Ding, Adrian Lister, Cody Karjadi, Rhoda Au, Honghuang Lin, Brian Bischoff, Phillip H Hwang.

Background: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied., Methods: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023). Participants were administered the 22-SinoNasal Outcome Test (SNOT-22) survey and a modified SNOT-22 instrument examining symptom importance. We determined importance rankings for individual symptoms and SNOT-22 symptom importance subdomains in two sets of subgroups-those pursuing ESS versus continuing medical management (CMT), and those on elexacaftor/tezacaftor/ivacaftor (ETI) versus not on ETI., Results: Among 69 participants, the highest priorities were nasal congestion (n = 48, 69.6% important), post-nasal discharge (32, 46.4%), facial pain (29, 43.3%), waking up tired (27, 39.1%), and fatigue (26, 37.7%). Those electing surgery (n = 23) prioritized sleep and psychological dysfunction symptoms compared to those pursuing CMT (n = 49) (sleep median score = 19.0 [interquartile range: 12.0, 25.0] vs. 4.5 [0.0, 12.8]; p < 0.0001; psychological = 17.0 [7.0, 26.0] vs. 7.0 [0.0, 15.8]; p = 0.002). ETI users had comparable SNOT-22 total symptom importance scores to non-ETI users (p = 0.14). Non-ETI users (n = 34) showed a trend toward prioritizing sleep symptoms compared to ETI users (n = 35) (13.0 [2.8, 22.3] vs. 6.0 [2.0, 17.0]; p = 0.055)., Conclusions: Nasal congestion and post-nasal discharge were top priorities reported by PwCF + CRS. Those electing surgery prioritized sleep and psychological symptoms, highlighting their importance in pre-operative discussions. Non-ETI users' prioritization of sleep improvement may highlight their unique disease impact and therapeutic needs; however, additional investigation is required., (© 2024 The Authors.

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., Methods: Patients diagnosed with SNM were prospectively enrolled in a multi-center patient registry. SNOT-22 scores were collected at the time of diagnosis and through the post-treatment period for up to 5 years. Multivariable regression analysis was used to identify drivers of variation in SNOT-22 subdomains., Results: Note that 234 patients were reviewed, with a mean follow-up of 22 months (3 months-64 months). Rhinologic, psychological, and sleep subdomains significantly improved versus baseline (all p < 0.05). Subanalysis of 40 patients with follow-up at all timepoints showed statistically significant improvement in rhinologic, extra-nasal, psychological, and sleep subdomains, with minimal clinically important difference met between 2 and 5 years in sleep and psychological subdomains. Adjuvant chemoradiation was associated with worse outcomes in rhinologic (adjusted odds ratio (5.22 [1.69-8.66])), extra-nasal (2.21 [0.22-4.17]) and ear/facial (5.53 [2.10-8.91]) subdomains. Pterygopalatine fossa involvement was associated with worse outcomes in rhinologic (3.22 [0.54-5.93]) and ear/facial (2.97 [0.32-5.65]) subdomains. Positive margins (5.74 [2.17-9.29]) and surgical approach-combined versus endoscopic (3.41 [0.78-6.05])-were associated with worse psychological outcomes. Adjuvant radiation (2.28 [0.18-4.40]) was associated with worse sleep outcomes., Conclusions: Sinonasal QOL improvements associated with treatment of SNM are driven by rhinologic, extra-nasal, psychological, and sleep subdomains., (© 2024 ARS‐AAOA, LLC.)

Background: Sociodemographic status (SDS) including race/ethnicity and socioeconomic status as approximated by education, income, and insurance status impact pulmonary disease in people with cystic fibrosis (PwCF). The relationship between SDS and chronic rhinosinusitis (CRS) remains understudied., Methods: In a prospective, multi-institutional study, adult PwCF completed the 22-Question SinoNasal Outcome Test (SNOT-22), Smell Identification Test (SIT), Questionnaire of Olfactory Disorder Negative Statements (QOD-NS), and Cystic Fibrosis Questionnaire-Revised (CFQ-R). Lund-Kennedy scores, sinus computed tomography, and clinical data were collected. Data were analyzed across race/ethnicity, sex, and socioeconomic factors using multivariate regression., Results: Seventy-three PwCF participated with a mean age of 34.7 ± 10.9 years and 49 (67.1%) were female. Linear regression identified that elexacaftor/tezacaftor/ivacaftor (ETI) use (β = ‒4.09, 95% confidence interval [CI] [‒6.08, ‒2.11], p < 0.001), female sex (β = ‒2.14, 95% CI [‒4.11, ‒0.17], p = 0.034), and increasing age (β = ‒0.14, 95% CI [‒0.22, ‒0.05], p = 0.003) were associated with lower/better endoscopy scores. Private health insurance (β = 17.76, 95% CI [5.20, 30.32], p = 0.006) and >16 educational years (β = 13.50, 95% CI [2.21, 24.80], p = 0.020) were associated with higher baseline percent predicted forced expiratory volume in one second (ppFEV 1 ). Medicaid/Medicare insurance was associated with worse endoscopy scores, CFQ-R respiratory scores, and ppFEV 1 (all p < 0.017), and Hispanic/Latino ethnicity was associated with worse SNOT-22 scores (p = 0.047), prior to adjustment for other cofactors. No other SDS factors were associated with SNOT-22, QOD-NS, or SIT scores., Conclusions: Differences in objective measures of CRS severity exist among PwCF related to sex, age, and ETI use. Variant status and race did not influence patient-reported CRS severity measures or olfaction in this study. Understanding how these factors impact response to treatment may improve care disparities among PwCF., Clinical Trials: NCT04469439., (© 2024 The Authors.

Key Points: Increased dupilumab utilization coincided with decreased ESS in patients with CRSwNP between 2019 and 2021. One potential confounder was the concurrent COVID-19 pandemic, which may have negatively impacted surgery utilization rates., (© 2024 ARS‐AAOA, LLC.)

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., Methods: In this prospective, multi-institutional study, 273 patients with SNMs who underwent definitive treatment with curative intent were evaluated. We used the University of Washington Quality of Life (UWQOL) instrument over 5 years from diagnosis to identify demographic, treatment, and disease-related factors that influence each of the 12 UWQOL subdomains from baseline to 5 -years post-treatment., Results: Multivariate models found endoscopic resection predicted improved pain (vs. nonsurgical treatment CI 2.4, 19.4, p = 0.01) and appearance versus open (CI 27.0, 35.0, p < 0.001) or combined (CI 10.4, 17.1, p < 0.001). Pterygopalatine fossa involvement predicted worse swallow (CI -10.8, -2.4, p = 0.01) and pain (CI -17.0, -4.0, p < 0.001). Neck dissection predicted worse swallow (CI -14.8, -2.8, p < 0.001), taste (CI -31.7, -1.5, p = 0.02), and salivary symptoms (CI -28.4, -8.6, p < 0.001). Maxillary involvement predicted worse chewing (CI 9.8, 33.2; p < 0.001) and speech (CI -21.8, -5.4, p < 0.001) relative to other sites. Advanced T stage predicted worse anxiety (CI -13.0, -2.0, p = 0.03)., Conclusions: Surgical approach, management of cervical disease, tumor extent, and site of involvement impacted variable UWQOL symptom areas. Endoscopic resection predicted better pain, appearance, and chewing compared with open. These results may aid in counseling patients regarding potential QOL expectations in their SNM treatment and recovery course., (© 2024 The Author(s).

Introduction: Olfactory dysfunction (OD) is common among people with cystic fibrosis (PwCF). The Questionnaire of Olfactory Disorders (QOD) is a validated instrument that evaluates olfactory-specific quality-of-life. The QOD minimal clinically important difference (MCID) and factors associated with olfactory improvement after elexacaftor/tezacaftor/ivacaftor have not been determined for PwCF., Methods: Prospective observational data were pooled from three studies that enrolled adult PwCF with chronic rhinosinusitis (CRS). QOD scores and disease characteristics were assessed. To evaluate internal consistency and calculate the QOD MCID, Cronbach's alpha and four distribution-based methods were employed. For participants who enrolled prior to elexacaftor/tezacaftor/ivacaftor, QOD scores were obtained at baseline and after elexacaftor/tezacaftor/ivacaftor initiation. Multivariable regression was used to identify factors associated with QOD improvement., Results: Of 129 PwCF included, 65 had QOD scores before and 3-6 months after starting elexacaftor/tezacaftor/ivacaftor. Mean baseline QOD score was 6.5 ± 7.9. Mean Cronbach's alpha was ≥0.85. The MCID estimates were as follows: Cohen's effect size = 1.6, standard error of measurement = 2.5, ½ baseline standard deviation = 4.0, and minimal detectable change = 6.9. Mean MCID was 3.7. Of those with pre/post elexacaftor/tezacaftor/ivacaftor QOD scores, the mean change in QOD was -1.3 ± 5.4. After elexacaftor/tezacaftor/ivacaftor, QOD improvement surpassed the MCID in 22% of participants (14/65). Worse baseline QOD scores and nasal polyps were associated with improved QOD scores after elexacaftor/tezacaftor/ivacaftor (both p < 0.04)., Conclusion: The QOD MCID in PwCF was estimated to be 3.7. Elexacaftor/tezacaftor/ivacaftor led to qualitative but not clinically meaningful improvements in QOD score for most PwCF; PwCF with worse baseline QOD scores and nasal polyps improved in a clinically significant manner., (© 2023 ARS‐AAOA, LLC.)

Background: Acoustic resonance therapy (ART) is a novel vibrational treatment that delivers patient-specific resonant frequency acoustic energy to the sinonasal cavities. In a pilot study, ART was effective for the acute treatment of nasal congestion. We conducted a sham-controlled randomized trial to validate the efficacy of ART when administered daily for 2 weeks., Methods: A total of 52 adult patients were enrolled in a multi-center, randomized, double-blinded, sham-controlled, interventional study evaluating ART administered by a vibrational headband. Patients received either active treatment or a non-therapeutic sham treatment twice daily over 2 weeks. Clinical endpoints were the average change in nasal congestion sub-score of the Total Nasal Symptom Score (TNSS) and the average change in composite TNSS., Results: ART resulted in a significantly greater mean change in the nasal congestion sub-score compared to sham (-0.87 [95% confidence interval [CI] -1.11, -0.62] vs. -0.44 [95% CI -0.64, -0.23], p = 0.008). ART also resulted in a significantly greater reduction in the composite TNSS versus sham, (-2.85 [95% CI -3.85, -1.85], vs. -1.32 [95% CI -2.27, -0.36], p = 0.027). The response rate, determined by a nasal congestion sub-score minimal clinically important difference of 0.23, was 80.8% for ART and 46.2% for sham, with an adjusted risk ratio of 1.95 (95% CI 1.26, 3.02, p = 0.003) in favor of ART. Safety endpoints showed no adverse events., Conclusion: ART is a safe and effective non-pharmacologic alternative for the treatment of nasal congestion., (© 2023 The Authors.

Key Points: ETD symptoms are present in 16% patients with underlying skull base pathology. Preoperative ETD symptoms improve following surgical treatment of skull base pathology.

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., Methods: Patients with previously untreated SNMs were prospectively enrolled (2015-2022) in a multicenter observational study. Baseline pretreatment QOL instruments (SNOT-22, UWQOL) were obtained along with demographics, comorbidities, histopathology/staging, tumor involvement, and symptoms. Multivariable regression models identified factors associated with reduced baseline QOL., Results: Among 204 patients, presenting baseline QOL was significantly reduced. Multivariable regression showed worse total SNOT-22 QOL in patients with skull base erosion (p = 0.02). SNOT-rhinologic QOL was worse in women (p = 0.009), patients with epistaxis (p = 0.036), and industrial exposure (p = 0.005). SNOT extranasal QOL was worse in patients with industrial exposure (p = 0.016); worse SNOT ear/facial QOL if perineural invasion (PNI) (p = 0.027). Squamous cell carcinoma pathology (p = 0.037), palate involvement (p = 0.012), and pain (p = 0.017) were associated with worse SNOT sleep QOL scores. SNOT psychological subdomain scores were significantly worse in patients with palate lesions (p = 0.022), skull base erosion (p = 0.025), and T1 staging (p = 0.023). Low QOL was more likely in the presence of PNI on UW health (p = 0.019) and orbital erosion on UW overall (p = 0.03). UW social QOL was worse if palatal involvement (p = 0.023) or PNI (p = 0.005)., Conclusions: Our findings demonstrate a negative impact on baseline QOL in patients with SNMs and suggest sex-specific and symptom-related lower QOL scores, with minimal histopathology association. Anatomical tumor involvement may be more reflective of QOL than T-staging, as orbital and skull base erosion, PNI, and palate lesions are significantly associated with reduced baseline QOL., (© 2023 ARS‐AAOA, LLC.)

Background: Allergic rhinitis (AR) is a common condition that is frequently associated with atopic inferior turbinate hypertrophy (ITH) resulting in nasal obstruction. Current guidelines support the use of subcutaneous allergen immunotherapy (SCIT) when patients fail pharmacologic management. However, there is a lack of consensus regarding the role of inferior turbinate reduction (ITR), a treatment that we hypothesize is cost-effective compared with other available treatments., Methods: We conducted a cost-effectiveness analysis comparing the following treatment combinations over a 5-year time horizon for AR patients presenting with atopic nasal obstruction who fail initial pharmacotherapy: (1) continued pharmacotherapy alone, (2) allergy testing and SCIT, (3) allergy testing and SCIT and then ITR for SCIT nonresponders, and (4) ITR and then allergy testing and SCIT for ITR nonresponders. Results were reported as incremental cost-effectiveness ratios (ICERs)., Results: For patients who fail initial pharmacotherapy, prioritizing ITR, either by microdebrider-assisting submucous resection or radiofrequency ablation, before SCIT was the most cost-effective strategy. Probabilistic sensitivity analysis demonstrated that prioritizing ITR before SCIT was the most cost-effective option in 95.4% of scenarios. ITR remained cost-effective even with the addition of concurrent septoplasty., Conclusion: For many AR patients who present with nasal obstruction secondary to atopic inferior turbinate hypertrophy that is persistent despite pharmacotherapy, ITR is a cost-effective treatment that should be considered prior to immunotherapy., Level of Evidence: NA - Laryngoscope, 2023 Laryngoscope, 134:1572-1580, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

Background: Comorbid chronic rhinosinusitis (CRS) remains unresolved for many people with cystic fibrosis (PwCF). While highly effective modulator therapy improves quality-of-life and symptom severity, the impact of this intervention and other factors associated with pursuing endoscopic sinus surgery (ESS) remains understudied., Methods: Adult PwCF + CRS were enrolled into a prospective, observational, multi-institutional study. Participants completed validated outcome measures to evaluate respiratory symptom severity, depression, headache, and sleep quality, as well as nasal endoscopy, sinus computed tomography (CT), and olfactory testing. Bivariate comparisons and regression modeling evaluated treatment cofactors, disease characteristics, and outcome measures associated with pursuing ESS., Results: Sixty PwCF were analyzed, including 24 (40%) who elected ESS. Pursuing ESS was associated with worse SinoNasal Outcome Test (SNOT-22) total, rhinologic, psychological, and sleep dysfunction domain scores; worse Patient Health Questionnaire-9-Revised depression scores; worse Pittsburgh Sleep Quality Index total scores; worse weight, role, emotion, and eating domain scores on the Cystic Fibrosis Questionnaire-Revised; more severe disease on nasal endoscopy; and lack of modulator therapy (all p < 0.050). Multivariable regression identified that worse SNOT-22 total score was associated with electing ESS (odds ratio [OR] 1.09, 95% confidence interval [CI] 1.02-1.16, p = 0.015) and elexacaftor/tezacaftor/ivacaftor (ETI) treatment (OR 0.04, 95% CI 0.004-0.34, p = 0.004) was associated with pursing medical therapy., Conclusions: Worse sinonasal symptom burden, lack of ETI treatment, sleep quality, depression, and nasal endoscopy scores were associated with electing ESS, while lung disease severity and sinus CT scores were not. ETI use was associated with lower odds of pursuing ESS independent of sinonasal symptom burden., (© 2023 ARS‐AAOA, LLC.)

Introduction: Maxillomandibular advancement (MMA) remains an effective procedure for the management of obstructive sleep apnea (OSA). Maxillary advancement may lead to anatomical changes that impair paranasal sinus drainage, leading to chronic sinus inflammation. The aim of this study was to describe the clinical features and outcomes of patients suffering from chronic rhinosinusitis (CRS) following MMA., Methods: This is a retrospective case series study. Our study included subjects diagnosed with CRS following MMA from January 1992 to October 2018 at Stanford Hospital. We screened 730 patients undergoing MMA and identified a total of 57 with CRS after MMA. A descriptive analysis was performed using clinical data including patient demographics, comorbidities, prior surgical history, physical exam manifestations, CT findings, and quality of life outcomes (SNOT-22)., Results: Out of 730 patients undergoing MMA, 57(7.8%) were found to have CRS after orthognathic surgery. Presenting symptoms included facial pain (92.5%), nasal drainage (75%), nasal obstruction (67.5%), and hyposmia (20%). Endoscopic examination revealed recirculation (30.5%), purulent discharge (27.7%), polypoid changes (22.2%), and scarring (13.8%). Preoperative CT prior to undergoing endoscopic sinus surgery (ESS) demonstrated mucosal thickening in maxillary (64.2%), anterior ethmoid (39.2%), frontal (14.2%), posterior ethmoid (10.7%), sphenoid sinus (14.2%), and ostiomeatal complex (55.3%). Average Lund-Mackay score was 5.5(±3.8). Additional CT findings included secondary ostium in the inferior meatus (42.8%). Forty patients (70.1%) underwent ESS at a mean of 4.6 years after MMA. Patients undergoing ESS experienced significant improvement in SNOT-22 scores at 12-months post-surgery ( P  = .018)., Conclusion: Patients undergoing maxillary advancement surgery are at risk of developing CRS postoperatively and should be advised of the risk of CRS associated with this procedure. Surgical treatment can be an option for medically refractory CRS related to MMA surgery., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction and Objective: Prior studies have provided variable results regarding environmental risk factors for epistaxis. These studies were conducted in varying climate zones, which may explain discrepancies in results. The objective of this study is to investigate correlations between season, temperature, and humidity on frequency of pediatric epistaxis across climate zones., Methods: Children seen in the outpatient setting for epistaxis were identified from the 2007-2010 IBM MarketScan database. Climate zones were assigned according to International Energy Conservation Code (IECC) classification, where temperature zones in the United States and territories were assigned on an ordinal scale from 1 (tropical) to 8 (subarctic), and humidity zones were categorized as moist, dry, or marine. The control population was a sample of all well-child visits matched by age and county., Results: We identified 184,846 unique children seen for epistaxis and 1,897,012 matched controls. Moderate temperature zones were associated with lower odds of epistaxis compared with the hottest and coldest zones. Humidity was associated inversely with epistaxis rates in moderate temperature zones but was not a significant predictor of epistaxis in climates with extreme heat. Additionally, summer was associated with lower odds of epistaxis compared to winter. Interestingly, however, there were significantly higher rates of cautery procedures during summer months, driven largely by increased procedures performed in clinic, as opposed to the operating room or emergency room., Conclusions: Environmental risk factors for epistaxis vary by climate zone. The model presented reconciles prior reports and may allow for more personalized clinical management based on regional climate., Level of Evidence: 3 Laryngoscope, 134:1450-1456, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

Objectives: To investigate how eustachian tube dysfunction symptoms change following surgical treatment of nonsinusitis-related nasal obstruction., Study Design: Retrospective chart review., Setting: Single academic center., Methods: We assessed patients who underwent septoplasty, turbinate reduction, or both for nasal obstruction. Chronic sinusitis patients were excluded. Eustachian tube dysfunction (ETD) symptoms were studied using the Eustachian Tube Dysfunction Questionnaire (ETDQ-7), collected preoperatively and postoperatively (1 week, 1 month, 3 months, 6 months postop). Patients with preoperative ETDQ-7 > 14.5 were considered to have clinically significant symptoms. Sinonasal outcomes test scores were also assessed. Pre- and postoperative ETDQ-7 scores were compared using t test. Multivariate linear regression analysis identified factors associated with ETDQ-7 change., Results: We analyzed 259 patients. Preoperatively, 37.5% of patients with nasal obstruction had clinically significant ETD symptoms. These patients exhibited significant improvement in ETDQ-7 at all postoperative timepoints from 23.3 ± 7.6 at baseline to 19.1 ± 9.1 at 1 week, 16.5 ± 8.0 at 1 month, 16.2 ± 7.8 at 3 months, and 16.7 ± 10.4 at 6 months (all P < .01). In patients without baseline ETD symptoms, (baseline ETDQ-7: 9.1 ± 2.3) ETDQ-7 scores did not change significantly at postoperative timepoints, except for an acute worsening at 1 week postoperatively (10.7 ± 5.1, P < .001). Regression analysis showed that higher preoperative ETDQ-7 score (β = -0.84, 95% confidence interval [CI]: -1.10 to -0.59) and postoperative antihistamine spray usage (β = -8.70, 95% CI: -14.20 to -3.20) were associated with ETDQ-7 improvement, while comorbid GERD (β = 7.50, 95% CI: 3.42-11.58) and asthma (β = 5.62, 95% CI: 0.80-10.45) were negatively associated with improvement., Conclusion: Surgical correction of nasal obstruction may improve ETD symptoms., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Introduction: Although the growth of digital tools for cognitive health assessment, there's a lack of known reference values and clinical implications for these digital methods. This study aims to establish reference values for digital neuropsychological measures obtained through the smartphone-based cognitive assessment application, Defense Automated Neurocognitive Assessment (DANA), and to identify clinical risk factors associated with these measures., Methods: The sample included 932 cognitively intact participants from the Framingham Heart Study, who completed at least one DANA task. Participants were stratified into subgroups based on sex and three age groups. Reference values were established for digital cognitive assessments within each age group, divided by sex, at the 2.5th, 25th, 50th, 75th, and 97.5th percentile thresholds. To validate these values, 57 cognitively intact participants from Boston University Alzheimer's Disease Research Center were included. Associations between 19 clinical risk factors and these digital neuropsychological measures were examined by a backward elimination strategy., Results: Age- and sex-specific reference values were generated for three DANA tasks. Participants below 60 had median response times for the Go-No-Go task of 796 ms (men) and 823 ms (women), with age-related increases in both sexes. Validation cohort results mostly aligned with these references. Different tasks showed unique clinical correlations. For instance, response time in the Code Substitution task correlated positively with total cholesterol and diabetes, but negatively with high-density lipoprotein and low-density lipoprotein cholesterol levels, and triglycerides., Discussion: This study established and validated reference values for digital neuropsychological measures of DANA in cognitively intact white participants, potentially improving their use in future clinical studies and practice., Competing Interests: RA is a scientific advisor to Signant Health and NovoNordisk, and a consultant to Biogen and the Davos Alzheimer’s Collaborative; she also serves as Director of the Global Cohort Development program for the Davos Alzheimer’s Collaborative.

Background: Sinonasal neoplasms, whether benign and malignant, pose a significant challenge to clinicians and represent a model area for multidisciplinary collaboration in order to optimize patient care. The International Consensus Statement on Allergy and Rhinology: Sinonasal Tumors (ICSNT) aims to summarize the best available evidence and presents 48 thematic and histopathology-based topics spanning the field., Methods: In accordance with prior International Consensus Statement on Allergy and Rhinology documents, ICSNT assigned each topic as an Evidence-Based Review with Recommendations, Evidence-Based Review, and Literature Review based on the level of evidence. An international group of multidisciplinary author teams were assembled for the topic reviews using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses format, and completed sections underwent a thorough and iterative consensus-building process. The final document underwent rigorous synthesis and review prior to publication., Results: The ICSNT document consists of four major sections: general principles, benign neoplasms and lesions, malignant neoplasms, and quality of life and surveillance. It covers 48 conceptual and/or histopathology-based topics relevant to sinonasal neoplasms and masses. Topics with a high level of evidence provided specific recommendations, while other areas summarized the current state of evidence. A final section highlights research opportunities and future directions, contributing to advancing knowledge and community intervention., Conclusion: As an embodiment of the multidisciplinary and collaborative model of care in sinonasal neoplasms and masses, ICSNT was designed as a comprehensive, international, and multidisciplinary collaborative endeavor. Its primary objective is to summarize the existing evidence in the field of sinonasal neoplasms and masses., (© 2023 The Authors.

Most research using digital technologies builds on existing methods for staff-administered evaluation, requiring a large investment of time, effort, and resources. Widespread use of personal mobile devices provides opportunities for continuous health monitoring without active participant engagement. Home-based sensors show promise in evaluating behavioral features in near real time. Digital technologies across these methodologies can detect precise measures of cognition, mood, sleep, gait, speech, motor activity, behavior patterns, and additional features relevant to health. As a neurodegenerative condition with insidious onset, Alzheimer disease and other dementias (AD/D) represent a key target for advances in monitoring disease symptoms. Studies to date evaluating the predictive power of digital measures use inconsistent approaches to characterize these measures. Comparison between different digital collection methods supports the use of passive collection methods in settings in which active participant engagement approaches are not feasible. Additional studies that analyze how digital measures across multiple data streams can together improve prediction of cognitive impairment and early-stage AD are needed. Given the long timeline of progression from normal to diagnosis, digital monitoring will more easily make extended longitudinal follow-up possible. Through the American Heart Association-funded Strategically Focused Research Network, the Boston University investigative team deployed a platform involving a wide range of technologies to address these gaps in research practice. Much more research is needed to thoroughly evaluate limitations of passive monitoring. Multidisciplinary collaborations are needed to establish legal and ethical frameworks for ensuring passive monitoring can be conducted at scale while protecting privacy and security, especially in vulnerable populations.

Background: Smartphone-based cognitive assessments have emerged as promising tools, bridging gaps in accessibility and reducing bias in Alzheimer disease and related dementia research. However, their congruence with traditional neuropsychological tests and usefulness in diverse cohorts remain underexplored., Methods and Results: A total of 406 FHS (Framingham Heart Study) and 59 BHS (Bogalusa Heart Study) participants with traditional neuropsychological tests and digital assessments using the Defense Automated Neurocognitive Assessment (DANA) smartphone protocol were included. Regression models investigated associations between DANA task digital measures and a neuropsychological global cognitive Z score (Global Cognitive Score [GCS]), and neuropsychological domain-specific Z scores. FHS participants' mean age was 57 (SD, 9.75) years, and 44% (179) were men. BHS participants' mean age was 49 (4.4) years, and 28% (16) were men. Participants in both cohorts with the lowest neuropsychological performance (lowest quartile, GCS1) demonstrated lower DANA digital scores. In the FHS, GCS1 participants had slower average response times and decreased cognitive efficiency scores in all DANA tasks ( P <0.05). In BHS, participants in GCS1 had slower average response times and decreased cognitive efficiency scores for DANA Code Substitution and Go/No-Go tasks, although this was not statistically significant. In both cohorts, GCS was significantly associated with DANA tasks, such that higher GCS correlated with faster average response times ( P <0.05) and increased cognitive efficiency (all P <0.05) in the DANA Code Substitution task., Conclusions: Our findings demonstrate that smartphone-based cognitive assessments exhibit concurrent validity with a composite measure of traditional neuropsychological tests. This supports the potential of using smartphone-based assessments in cognitive screening across diverse populations and the scalability of digital assessments to community-dwelling individuals.

Background: Smartphone-based digital technology is increasingly being recognized as a cost-effective, scalable, and noninvasive method of collecting longitudinal cognitive and behavioral data. Accordingly, a state-of-the-art 3-year longitudinal project focused on collecting multimodal digital data for early detection of cognitive impairment was developed., Methods and Results: A smartphone application collected 2 modalities of cognitive data, digital voice and screen-based behaviors, from the FHS (Framingham Heart Study) multigenerational Generation 2 (Gen 2) and Generation 3 (Gen 3) cohorts. To understand the feasibility of conducting a smartphone-based study, participants completed a series of questions about their smartphone and app use, as well as sensory and environmental factors that they encountered while completing the tasks on the app. Baseline data collected to date were from 537 participants (mean age=66.6 years, SD=7.0; 58.47% female). Across the younger participants from the Gen 3 cohort (n=455; mean age=60.8 years, SD=8.2; 59.12% female) and older participants from the Gen 2 cohort (n=82; mean age=74.2 years, SD=5.8; 54.88% female), an average of 76% participants agreed or strongly agreed that they felt confident about using the app, 77% on average agreed or strongly agreed that they were able to use the app on their own, and 81% on average rated the app as easy to use., Conclusions: Based on participant ratings, the study findings are promising. At baseline, the majority of participants are able to complete the app-related tasks, follow the instructions, and encounter minimal barriers to completing the tasks independently. These data provide evidence that designing and collecting smartphone application data in an unsupervised, remote, and naturalistic setting in a large, community-based population is feasible.

Background: Budesonide irrigations (BIs) are commonly used to control inflammation in chronic rhinosinusitis (CRS). In 2016 we reported an analysis of long-term BI with regard to hypothalamic-pituitary-adrenal axis function. We present a follow-up analysis in a larger cohort of patients with longer follow-up., Methods: Patients were candidates for stimulated cortisol testing after regularly performing BI for CRS at least daily for ≥6 months. We retrospectively evaluated all patients who received stimulated cortisol testing at our center between 2012 and 2022. We correlated cortisol levels with the use of BI and other forms of corticosteroids., Results: We analyzed 401 cortisol test results in 285 patients. The mean duration of use was 34 months. Overall, 21.8% of patients were hypocortisolemic (<18 ug/dL) at first test. In patients who used only BI, the rate of hypocortisolemia was 7.5%, whereas in patients who also used concurrent oral and inhaled corticosteroids, the rate was 40% to 50%. Lower cortisol levels were associated with male sex (p < 0.0001) and concomitant use of oral and inhaled steroids (p < 0.0001). Duration of BI use was not significantly associated with lower cortisol levels (p = 0.701), nor was greater dosing frequency (p = 0.289)., Conclusion: Prolonged use of BI alone is not likely to cause hypocortisolemia in the majority of patients. However, concomitant use of inhaled and oral steroids and male sex may be associated with hypocortisolemia. Surveillance of cortisol levels may be considered in vulnerable populations who use BI regularly, particularly in patients using other forms of corticosteroids with known systemic absorption., (© 2023 ARS-AAOA, LLC.)

Objective: The aim of the study was to characterize the incidence and management of difficult tracheal intubations (DTIs) in nasopharyngeal carcinoma (NPC) after primary radiation therapy (RT)., Methods: The study was a retrospective review of airway assessment and outcomes in post-RT NPC patients. Primary analysis was performed on patients who underwent post-RT procedures, who were split into non-DTI and DTI groups. Patients were classified as DTI if they (i) required >1 attempt to intubate, (ii) failed to be intubated, or (iii) experienced complications attributed to airway management. Secondary analysis was performed between patients who underwent post-RT procedures (procedure group) and those who did not (control group)., Results: One-hundred and fifty patients were included, and 71.3% underwent post-RT procedures, with no differences in characteristics between the procedure and control groups. One-hundred and fifty procedures were identified, and 28.0% were categorized as DTI. There was no difference in patient characteristics or airway assessment measures between DTI and non-DTI groups. Regression analysis revealed concurrent cervical mobility restriction, and trismus increased DTI incidence by 7.1-fold (p = 0.011). Being non-White was an independent predictor of DTI. The incidence of high-grade intraoperative laryngoscopic view was lower in the non-DTI compared to the DTI group (20.4% vs. 64.3%, p < 0.0001). Failure to intubate occurred in 2.0% of cases, and 6.0% cases had perioperative complications. Based on preoperative assessment, sensitivity of predicting DTI was 54.8% and specificity was 63.9%., Conclusion: NPC patients frequently undergo post-RT procedures requiring complex airway management. Rates of DTI and failed intubation are significantly higher than those in the general surgical population, and the ability to predict DTI with standard preoperative airway measures is poor., Level of Evidence: 4 Laryngoscope, 134:120-126, 2024., (© 2023 The American Laryngological, Rhinological and Otological Society, Inc.)

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. QOL was assessed using the 22-item Sino-Nasal Outcome Test (SNOT-22) and University of Washington Quality of Life Questionnaire (UWQOL) instruments at pretreatment baseline and multiple follow-ups through 5 years posttreatment. Multivariable modeling was used to determine demographic, disease, and treatment factors associated with disease-specific and generalized physical and social/emotional function QOL., Results: One hundred ninety-four patients with SNM were analyzed. All QOL indices were impaired at pretreatment baseline and improved after treatment. SNOT-22 scores improved 3 months and UWQOL scores improved 6 to 9 months posttreatment. Patients who underwent open compared with endoscopic tumor resection had worse generalized QOL (p < 0.001), adjusted for factors including T stage. Pterygopalatine fossa (PPF) involvement was associated with worse QOL (SNOT-22, p < 0.001; UWQOL Physical dimension, p = 0.02). Adjuvant radiation was associated with worse disease-specific QOL (p = 0.03). Neck dissection was associated with worse generalized physical function QOL (p = 0.01). Positive margins were associated with worse generalized social/emotional function QOL (p = 0.01)., Conclusion: Disease-specific and generalized QOL is impaired at baseline in patients with SNM and improves after treatment. Endoscopic resection is associated with better QOL. PPF involvement, adjuvant radiation, neck dissection, and positive margins were associated with worse QOL posttreatment., (© 2023 ARS-AAOA, LLC.)

Background: Traditional management of olfactory neuroblastoma (ONB) includes margin-negative resection with removal of cribriform plate, dura, and olfactory bulb, regardless of intracranial disease. This approach may be overtreating certain patients. Our investigation examines risk factors associated with occult intracranial disease to optimize therapeutic outcomes., Methods: This retrospective, multi-institutional cohort study examined clinical covariates associated with occult intracranial involvement. Patient demographics, staging, Hyam's grade, and pathologic involvement of dura, olfactory bulb/tract, and brain were collected. Diagnostic imaging was reviewed. Positive and negative predictive value (NPV) were estimated along with effect size estimates. Cox hazard regression examined associations with overall survival (OS) and disease-free survival (DFS)., Results: A total of 224 subjects with new diagnoses of ONB (2005-2021) were identified. Skull base bone involvement on computed tomography (CT) had the highest NPV for pathologic dura (88.0%), olfactory bulb (88%), and brain involvement (97.3%). Hyam's grade category was significantly associated with dural involvement (φ C  = 0.26; 95% confidence interval [CI]: 0.16, 0.42). Subjects without radiologic skull base involvement (n = 66) had pathologic positivity of 12.1%. Within this subgroup, Hyam's grade was clinically significant for dural positivity (φ = 0.34; 95% CI: -0.12, 0.71) with 28.6% involvement in high grade tumors. Neither clinical nor pathologic positivity of intracranial structures were associated with significantly different OS or DFS., Conclusions: Both CT and magnetic resonance imaging (MRI) had reasonably good NPV for involvement of dura and olfactory bulb. Higher Hyam's grade was associated with dural involvement. Patients with low-grade tumors not involving the skull base may be suitable for avoiding skull base resection; however, further investigation is warranted., (© 2023 ARS-AAOA, LLC.)

Objective: Social media (SM) is an increasingly popular medium for the medical community to engage with patients, trainees, and colleagues. This review aimed to identify reported uses of SM in otolaryngology-head and neck surgery (OHNS), assess the quality of evidence supporting these uses, and identify gaps in the literature. With the relative lack of regulatory guidelines for the development of SM content, we hypothesized that the quality of content available on SM would be highly variable., Data Sources and Methods: A scoping review was performed of English-language peer-reviewed studies published to date discussing SM use in any form within OHNS. Three reviewers independently screened all abstracts. Two reviewers independently extracted data of interest from the full text of articles identified from the preliminary abstract screen., Results: 171 studies were included, with 94 (54.9%) studies published between 2020 and 2022. 104 (60.8%) studies were conducted in the US. 135 (78.9%) used cross-sectional or survey-based methodology; only 7 (4.1%) were controlled studies. SM was most commonly employed for professional networking (n = 37 [21%]), and within subspecialties of otology (n = 38 [22%]) and rhinology/allergy (n = 25 [15%]). Facebook was most frequently used for study recruitment (n = 23 [13.5%]), YouTube for patient education (n = 15 [14.6%]), and Twitter for professional networking (n = 16 [9.4%])., Conclusion: SM use within OHNS is increasing rapidly, with applications including patient education, professional networking, and study recruitment. Despite myriad articles, there remains a paucity of well-controlled studies. As SM becomes integrated into healthcare, particularly for applications directly impacting patient care, higher levels of evidence are needed to understand its true impact.

Background: Acute invasive fungal sinusitis (AIFS) is an aggressive disease that requires prompt diagnosis and multidisciplinary treatment given its rapid progression. However, there is currently no consensus on diagnosis, prognosis, and management strategies for AIFS, with multiple modalities routinely employed. The purpose of this multi-institutional and multidisciplinary evidence-based review with recommendations (EBRR) is to thoroughly review the literature on AIFS, summarize the existing evidence, and provide recommendations on the management of AIFS., Methods: The PubMed, EMBASE, and Cochrane databases were systematically reviewed from inception through January 2022. Studies evaluating management for orbital, non-sinonasal head and neck, and intracranial manifestations of AIFS were included. An iterative review process was utilized in accordance with EBRR guidelines. Levels of evidence and recommendations on management principles for AIFS were generated., Results: A review and evaluation of published literature was performed on 12 topics surrounding AIFS (signs and symptoms, laboratory and microbiology diagnostics, endoscopy, imaging, pathology, surgery, medical therapy, management of extrasinus extension, reversing immunosuppression, and outcomes and survival). The aggregate quality of evidence was varied across reviewed domains., Conclusion: Based on the currently available evidence, judicious utilization of a combination of history and physical examination, laboratory and histopathologic techniques, and endoscopy provide the cornerstone for accurate diagnosis of AIFS. In addition, AIFS is optimally managed by a multidisciplinary team via a combination of surgery (including resection whenever possible), antifungal therapy, and correcting sources of immunosuppression. Higher quality (i.e., prospective) studies are needed to better define the roles of each modality and determine diagnosis and treatment algorithms., (© 2023 ARS-AAOA, LLC.)

Background: Postoperative epistaxis is a known possibility following endoscopic sinonasal surgery. Tranexamic acid (TXA) has been shown to reduce intraoperative blood loss and improve the visual field. This study evaluated the clinical efficacy of TXA when given at end of surgery to reduce postoperative bleeding., Methods: This randomized, double-blinded placebo-controlled trial was conducted from April to November 2021. Patients scheduled to undergo endoscopic sinus or nasal surgery were randomized to receive an intravenous dose of 1 g TXA or saline intraoperatively prior to extubation. A 10-in. visual analog scale (VAS) was used to query patients regarding postoperative bleeding each day for 1 week. The medical record was examined to determine the need for additional evaluations or interventions for epistaxis., Results: Forty patients completed the study. The mean ± SD postoperative bleeding VAS for the TXA group on the day of surgery was not significantly different from the saline group (4.82 ± 2.18 in. vs. 5.03 ± 2.14 in., p = 0.8). There were no significant differences between treatment arms on any postoperative day through day 7 (0.67 ± 1.84 in. vs. 0.87 ± 0.99 in., p = 0.7), nor in the reduction in VAS compared to the respective baseline on the day of surgery. There were no significant differences in terms of additional interventions (e.g., additional evaluation in recovery, ED, or clinic, need for packing, or return to the operating room [OR])., Conclusion: Although TXA has previously demonstrated efficacy to reduce intraoperative bleeding during sinonasal surgery, when postoperative bleeding is already minimal at baseline, TXA does not appear to reduce it significantly further., (© 2023 ARS-AAOA, LLC.)

Indications Corridor and Limits of Exposure: The endoscopic endonasal transtuberculum approach grants access to suprasellar and retrochiasmatic lesions with hypothalamic involvement. Here, we present a case of a 13-year-old boy with a history of stunted growth, decreased vision, headaches, and low energy with a tuberoinfundibular craniopharyngioma. The patient consented to the procedure., Anatomic Essentials Need for Preoperative Planning and Assessment: Evaluation of the sphenoid sinus pneumatization, internal carotid artery disposition, presence of clinoidal rings, variations of the infrachiasmatic corridor (optic chiasm location, height of dorsum sella), and location of the pituitary stalk are crucial for surgical strategy., Essentials Steps of the Procedure: Harvesting of nasoseptal flap and access to the sphenoid sinus; drilling the sella, tuberculum, and chiasmatic sulcus up to the limbus sphenoidalis and laterally exposing the clinoidal carotid artery segment; wide dural opening to the level of distal rings inferolaterally and falciform ligaments superolaterally; identification and coagulation of superior hypophyseal branches providing tumor supply; intracapsular dissection and debulking and subpial sharp dissection at the hypothalamic tumor interface to achieve complete removal; and reconstruction with inlay collagen, fascia lata, and nasoseptal flap., Pitfalls/avoidance of Complications: Preservation of the superior hypophyseal arteries and stalk is essential for preventing pituitary dysfunction. Preoperative reckoning of hypothalamic invasion and identification of adequate interface aids in avoiding complications. To reduce CSF leak risk, multilayer reconstruction was performed and lumbar drain placed postoperatively., Variants and Indications for Their Use: For retroclival extension, intradural pituitary transposition should be considered to expand the corridor; in patients with preoperative hypopituitarism, pituitary sacrifice is most effective to increase retroclival access., (Copyright © Congress of Neurological Surgeons 2023.

Introduction: We examined for associations between potentially modifiable risk factors across the adult life course and incident dementia., Methods: Participants from the Framingham Heart Study were included (n = 4015). Potential modifiable risk factors included education, alcohol intake, smoking, body mass index (BMI), physical activity, social network, diabetes, and hypertension. Cox models were used to examine associations between each factor and incident dementia, stratified by early adult life (33-44 years), midlife (45-65 years), and late life (66-80 years)., Results: Increased dementia risk was associated with diabetes (hazard ratio [HR] = 1.62; 95% confidence interval [CI] = 1.07-2.46) and physical inactivity (HR = 1.57; 95% CI = 1.12-2.20) in midlife, and with obesity (HR = 1.76; 95% CI = 1.08-2.87) in late life. Having multiple potential modifiable risk factors in midlife and late life was associated with greater risk., Discussion: Potentially modifiable risk factors individually have limited impact on dementia risk in this population across the adult life course, although in combination they may have a synergistic effect., Highlights: Diabetes and physical inactivity in midlife is associated with increased dementia risk. Obesity in late life is associated with increased dementia risk. Having more potentially modifiable risk factors in midlife and late life is associated with greater dementia risk., (© 2023 the Alzheimer's Association.)
