Neuropsychiatric Symptoms Mediated the Relationship Between Odor Identification and Cognition in Alzheimer's Disease Spectrum: A Structural Equation Model Analysis

Background: Odor identification dysfunction is an early predictor of the development of Alzheimer's disease (AD), but neuropsychiatric symptoms (NPS), which are common in AD and mild cognitive impairment (MCI), are also associated with odor identification dysfunction. Whether NPS affect the specificity of using odor identification dysfunction to predict cognitive decline in AD and MCI remains unclear.

Methods: Patients (233 with MCI and 45 with AD) and 45 healthy controls (HCs) underwent assessments of odor identification (Sniffin' Sticks), NPS (Neuropsychiatric Inventory-12), and cognitive function (global cognition, memory, language, executive function, visual-spatial skill, and attention). Structural equation modeling (SEM) with bootstrapping estimation was conducted to explore the relationships between odor identification, NPS, and cognition.

Results: Patients with NPS showed significantly worse performance in odor identification and cognition than patients without NPS and HCs. The SEM showed odor identification to be positively associated with cognition, and cognition had special indirect effects on odor identification through affective and psychosis symptoms (two factors extracted from Neuropsychiatric Inventory-12). Additionally, affective and psychosis symptoms partially mediated the effect of cognition on odor identification.

Conclusion: Neuropsychiatric symptoms are associated with odor identification dysfunction in patients with AD and MCI. Studies exploring the relationship between odor identification dysfunction and cognitive decline in patients with AD and MCI should include an assessment of affective and psychosis symptoms, and adjust their confounding effects.

An effective simulation- and measurement-based workflow for enhanced diagnostics in rhinology

Physics-based analyses have the potential to consolidate and substantiate medical diagnoses in rhinology. Such methods are frequently subject to intense investigations in research. However, they are not used in clinical applications, yet. One issue preventing their direct integration is that these methods are commonly developed as isolated solutions which do not consider the whole chain of data processing from initial medical to higher valued data. This manuscript presents a workflow that incorporates the whole data processing pipeline based on a Jupyter environment. Therefore, medical image data are fully automatically pre-processed by machine learning algorithms. The resulting geometries employed for the simulations on high-performance computing systems reach an accuracy of up to 99.5% compared to manually segmented geometries. Additionally, the user is enabled to upload and visualize 4-phase rhinomanometry data. Subsequent analysis and visualization of the simulation outcome extend the results of standardized diagnostic methods by a physically sound interpretation. Along with a detailed presentation of the methodologies, the capabilities of the workflow are demonstrated by evaluating an exemplary medical case. The pipeline output is compared to 4-phase rhinomanometry data. The comparison underlines the functionality of the pipeline. However, it also illustrates the influence of mucosa swelling on the simulation. Graphical Abstract Workflow for enhanced diagnostics in rhinology.

Age-Related Cognitive Decline and the Olfactory Identification Deficit Are Associated to Increased Level of Depression

PURPOSE

Previous studies reported a correlation between olfactory function and depression. However, in literature, no data are available for the correlation between depression and all other factors such as age, sex, olfactory, gustatory, and cognitive function in healthy subjects taken together. The aim of this study was to provide a systematic account regarding the association between those variables in a non-clinical population.

METHODS

Two hundred and seventy-three participants were recruited with an age range of 19-84 years. Olfactory, gustatory, cognitive function, and depression level were evaluated by means of the following tests: the Sniffin' Sticks test, Taste Strips test, Montreal Cognitive Assessment (MoCA), and Beck Depression Inventory (BDI).

RESULTS

In our data, an age-related decrease in olfactory and gustatory function and a decline in cognitive functions such as attention, memory, and language were observed. Instead, no significant differences were observed for the depression level in relation to the different age ranges. However, our results indicated that the depression level could be associated to sex, odor identification impairment, and decreased attention and language.

CONCLUSION

Sex, the odor identification impairment, and an age-related decrease in attention and language are associated with increased level of depression in healthy subjects. Our data can be useful and informative for health care workers, that is, to have adequate preventive strategies to be used whenever these conditions are detected and recognized.

Comparison of Quality of Life Before and After Septoplasty With Short Form-36

The authors aimed to evaluate quality of life after septal surgery with Short Form-36 survey, and the effectiveness of the survey. Nasal symptoms (nasal obstruction, facial pain, catarrh), and general quality of life (using the Turkish version of the Short Form-36 questionnaire) were assessed preoperatively and at 1st and 6th postoperative months. Acoustic rhinometry and rhinomanometry were assessed preoperatively and at 6th postoperative month. Data from 78 patients were analyzed. This prospective clinical study was conducted on patients complaining of nasal obstruction with nasal septal deviation. Seventy-eight patients were included in the study. Fourty-two patients (53.8%) were male and 36 patients (46.2%) were female. At 1st postoperative month, nasal obstruction, facial pain and catarrh scores significantly improved in all, 46, 18 patients, respectively (P < 0.0001). At 6th postoperative month, scores nonsignificantly worsened by 1 point in 12, 6, 12 patients, respectively. Nasal volume significantly increased and total resistance significantly decreased at 6th month (P < 0.0001). Compared to preoperative values, all items except social function and bodily pain significantly increased at 1st postoperative month. Compared to values at 1st postoperative month, only bodily pain score decreased at 6th postoperative month. One patient presented with septal perforation. Septoplasty is a well-established technique to reduce nasal obstruction and improve quality of life. SF-36 may be used as a reliable measure of changes in quality of life after septal surgery.

[State of the art of quality-of-life measurement in patients with chronic otitis media and conductive hearing loss]

The evaluation of results after middle ear reconstruction has been mainly based on functional parameters. In clinical practice as well as in otological research, the pure tone audiogram represents the gold standard in the assessment of the postoperative outcome. In order to assess the patient's subjective outcome, outcome analyzes focus increasingly on the health-related quality of life (HRQOL). However, the evaluation of HRQOL requires reliable and validated measuring instruments. A modest number of validated questionnaires for determination of the disease-specific HRQOL in patients with chronic otitis media and/or conductive hearing loss are currently available. Three of seven available questionnaires were developed and validated in the German-speaking countries, the Zurich Chronic Middle Ear Inventory 21 (ZCMEI-21), the Chronic Otitis Media Outcome Test 15 (COMOT-15) and the Stapesplasty Outcome Test 25 (SPOT-25). In this review, all seven available disease-specific measuring instruments as well as the generic questionnaires, which were used in previous clinical trials, are explained and current findings of quality-of-life research in patients with chronic otitis media and/or conductive hearing loss are presented.

Assessment of non-response in quality control of nasal septal surgery

OBJECTIVE

This study evaluated the effect of mail non-response on the validity of the results of nasal septal surgery.

METHOD

Six months post-operatively, questionnaires with both prospective and retrospective ratings were mailed to patients. Patients who did not respond (non-responders) were contacted by telephone. This study compared two cohorts of patients using different interviewers (a nurse and a surgeon). Cohort one consisted of 182 patients (with 67 per cent mail response), and cohort two consisted of 454 patients (with 64.8 per cent mail response).

RESULTS

In both cohorts, the improvement in obstruction scores was significantly better among mail responders than among non-responders (telephone interviewees) using prospective ratings, but worse using retrospective ratings.

CONCLUSION

Mail responders had better improvement in nasal obstruction after septoplasty than non-responders. Therefore, low response rates may cause an overestimation of the results. The retrospective ratings obtained through telephone interviews are less reliable because they are influenced by memory and the patients' tendency to give socially acceptable answers.

Long-term olfaction outcomes in transnasal endoscopic skull-base surgery: a prospective cohort study comparing electrocautery and cold knife upper septal limb incision techniques

BACKGROUND

Olfactory nerve fibers are at risk of injury during transnasal endoscopic skull-base approaches. Olfactory outcomes for various techniques have not been thoroughly investigated. This study aims to report long-term olfactory outcomes when a cold knife upper septal limb incision technique is used compared to monopolar cautery.

METHODS

A prospective cohort study was performed at a tertiary referral center. Adult patients undergoing endoscopic approaches with septal incisions were randomized to cold knife or monopolar cautery groups. Patient demographics, clinical history, surgical data, and outcomes were collected. Preoperative, 3-month, and 12-month postoperative scores on the University of Pennsylvania Smell Inventory Test (UPSIT) and 22-item Sino-Nasal Outcome Test (SNOT-22) were measured. Fisher's exact tests were performed for categorical variables and t tests were performed for continuous variables.

RESULTS

Twenty-two (22) patients (10 cold knife, 12 cautery) were enrolled between March 2016 and August 2017. The average age ± standard deviation was 50.2 ± 14.0 years (p = 0.59), 54% (p = 0.69) were female, and the primary pathology was pituitary adenoma (73%, p = 1.00). Preoperative, 3-month, and 12-month postoperative UPSIT scores were similar between the cold knife and cautery groups (32.8 vs 32.4, p = 0.80; 33.1 vs 33.0, p = 0.96; 33.6 vs 33.3, p = 0.84). On the "sense of smell/taste" question of the SNOT-22, there was also no difference at all time points (p > 0.22).

CONCLUSION

There was no significant change in patient UPSIT scores 1 year after transnasal skull-base approaches, and no short-term or long-term differences between cold knife and cautery upper septal limb incision techniques. Our study supports an individualized approach based on surgeon preference.

A comparison of symptoms and quality of life before and after nasal septoplasty and radiofrequency therapy of the inferior turbinate

Background

The primary goal of this study is to compare pre- and postoperative symptoms and health related quality of life (HQOL) in 57 patients who underwent septoplasty (group-1), 56 patients who underwent septoplasty combined with radiofrequency therapy of inferior turbinates (RFIT) (group-2) and 58 patients who underwent RFIT alone (group-3). The secondary goal is to investigate if the change in symptoms and HQOL differed between these three patient groups after surgery.

Methods

All patients reported symptoms on a visual analogue scale (VAS) and HQOL on Sino-Nasal-Outcome-Test-20 (SNOT-20) and Short-Form-Health-Survey-36 (SF-36) before and 6 months after surgery. The pre- and postoperative scores and improvement were compared within and between the three patient groups.

Results

Preoperatively the three patient groups had a fairly similar symptom burden and HQOL, except for group-1 which reported more symptoms of oral breathing than group-3 (p < 0.01) and group-3 which reported more problems in the ear/facial--subset of SNOT-20 and in the general-mental-health-domain of SF-36 than group-1 (p < 0.01).

Postoperatively all patient groups reported improved symptom scores of nasal obstruction, nasal discharge, snoring, oral breathing and reduced general health (p < 0.01), and better HQOL (p < 0.05). Patients in group-2 had less symptoms of nasal obstruction than group-3 (p < 0.05). Postoperative symptom score for nasal obstruction was 29.1 (SD67.6) in group-1, 27.5 (SD22.5) in group-2 and 37.2 (SD24.8) in group-3. Revision cases reported more nasal obstruction postoperatively; 41.3 (SD27) than non revision cases; 28.6 (SD24) (p < 0.01).

The HQOL after surgery was about the same in all three patient groups, but we found that patients with comorbidities as sleep apnea and asthma reported worse HQOL than other patients (p < 0.01).

Conclusion

Surgical treatment of nasal obstruction led to less symptoms and better HQOL for all three patient groups. Comparing the postoperative scores between the patient groups we find that all groups reached the same level of HQOL. Regarding symptoms, the patients who underwent septoplasty combined with RFIT reported postoperatively less nasal obstruction than patients who underwent RFIT alone which may indicate that a combined procedure of septoplasty and RFIT is better than RFIT alone to treat nasal obstruction. Furthermore, revision cases, patients with sleep apnea and asthma patients seem to have poorer outcome after surgery than other patients. Both disease specific and general QOL instruments add valuable information for identifying factors influencing outcome.

Evaluation of non-response in quality control of nasal septal surgery

OBJECTIVE

Questionnaires are often used to assess the results of nasal septoplasty, but response rates vary widely. The possible bias caused by non-responders was evaluated to determine the validity of questionnaire results.

METHODS

Post-operative questionnaires employing visual analogue scales for nasal obstruction were mailed to 182 patients. The 62 non-responders (34.1 per cent) were contacted by telephone, 58 (93.5 per cent) of whom were contactable and responded orally to the questionnaire.

RESULTS

Non-responders were younger, but no different from responders with regard to gender, smoking habits or allergies. Post-operative visual analogue scale obstruction scores were slightly, but not statistically, higher in non-responders. However, because non-responders' pre-operative scores were lower, obstruction scores improved less than in responders. The main reason for not responding was forgetfulness. Some would have preferred an electronic version of the questionnaire.

CONCLUSION

Although post-operative obstruction scores did not differ between the groups, nasal obstruction scores improved more among responders than non-responders. Thus, low response rates may cause bias.

Cost utility analysis of endoscopic sinus surgery for chronic rhinosinusitis with and without nasal polyposis

OBJECTIVE

To evaluate the cost-effectiveness of endoscopic sinus surgery (ESS) compared to medical therapy for patients with chronic rhinosinusitis (CRS) with and without nasal polyposis (NP).

STUDY DESIGN

Cohort-style Markov decision-tree economic model with a 36-year time horizon.

METHODS

Two cohorts of 229 CRS patients with and without NP who underwent ESS were compared with a matched cohort of 229 CRS patients from the Medical Expenditures Survey Panel database (Agency for Healthcare Research and Quality, Rockville, MD) who underwent medical management. Utility scores were calculated from sequential patient responses to the EuroQol five-dimensions questionnaire. Decision-tree analysis and a 10-state Markov model utilized published event probabilities and primary data to calculate long-term costs and utility. The primary outcome was the incremental cost per quality-adjusted life year (QALY). Thorough sensitivity analyses were performed.

RESULTS

The reference case for CRS with NP yielded an incremental cost-effectiveness ratio (ICER) for ESS versus medical therapy of $5,687.41/QALY. The reference case for CRS without NP yielded an ICER of $5,405.44/QALY. The cost-effectiveness acceptability curve in both cases demonstrated 95% certainty that the ESS strategy was the most cost-effective option at a willingness-to-pay threshold of $20,000/QALY or higher. These results were robust to one-way and probabilistic sensitivity analysis.

CONCLUSION

This study demonstrates the cost-effectiveness of ESS compared to medical therapy alone for the management of CRS patients both with and without NP. The presence of nasal polyps was not found to affect the overall cost-effectiveness of ESS.

Comprehensive review on endonasal endoscopic sinus surgery

Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3-4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

Evidence-based surgery for chronic rhinosinusitis with and without nasal polyps

Meta-analysis of both large outcome studies as well as cohort studies support the safety and efficacy of Endoscopic Sinus Surgery for Chronic Rhinosinusitis. The efficacy of endoscopic sinus surgery is demonstrated in the improvement of both disease-specific and generic QOL as well as objective measures. However, this must be interpreted together with a well-recognized long-term 15-20 % revision rate, seen more often in patients with ASA trias and cystic fibrosis as well as osteitis and previous surgery. The effect of surgery is higher in managing nasal obstruction (effect size 1.7) and less so hyposmia (effect size 0.8). Allergy has an additive role on the symptomatology of CRS; however, its role if any on the outcome of ESS for CRS is unclear. The concurrent presence of aspiring sensitivity and asthma is associated with increased disease burden and more revision surgeries. Improved phenotyping of CRS may lead in the future to better tailoring of surgical treatments.

Functional endoscopic sinus surgery improves sinus-related symptoms and quality of life in children with chronic rhinosinusitis: a systematic analysis and meta-analysis of published interventional studies

AIM

To assess the current knowledge and evaluate the quality of evidence in the use of FESS for the treatment of chronic rhinosinusitis in children, regarding the respective changes in the quality-of-their-life (QoL) and the outcome that follows the operation.

MATERIALS/METHODS

Systematic literature review in Medline and other database sources and meta-analysis of pooled data.

RESULTS

15 studies were systematically analyzed. Four represented Level II, five Level III, and six Level IV evidence. The total number of treated patients was 1301. Thirteen research groups reported that pediatric FESS is an effective treatment for chronic rhinosinusitis; the respective positive outcome ranged between 71 and 100% of operated children. Five studies concluded that this treatment modality is associated with significant improvement in the children's postoperative QoL. Systemic diseases and environmental factors may have unfavourable prognostic effects; cystic fibrosis is associated with at least 50% recurrence rate. The rate of major complications following pediatric FESS is 0.6%, and the respective rate of minor complications 2%.

CONCLUSION

The surgical management in children with chronic rhinosinusitis, despite the reservations expressed by many clinicians, is effective when optimal medical treatment proves unsuccessful (grade B strength of recommendation), and is associated with improvement in the children's QoL (grade B strength of recommendation). FESS also improves the sinusitis-associated symptoms and QoL in children with cystic fibrosis (grade C strength of recommendation. Most complications of pediatric FESS reported in the literature are minor, and associated with difficulties in the postoperative assessment and care of pediatric patients.

Fluid mechanics based classification of the respiratory efficiency of several nasal cavities

The flow in the human nasal cavity is of great importance to understand rhinologic pathologies like impaired respiration or heating capabilities, a diminished sense of taste and smell, and the presence of dry mucous membranes. To numerically analyze this flow problem a highly efficient and scalable Thermal Lattice-BGK (TLBGK) solver is used, which is very well suited for flows in intricate geometries. The generation of the computational mesh is completely automatic and highly parallelized such that it can be executed efficiently on High Performance Computers (HPCs). An evaluation of the functionality of nasal cavities is based on an analysis of pressure drop, secondary flow structures, wall-shear stress distributions, and temperature variations from the nostrils to the pharynx. The results of the flow fields of three completely different nasal cavities allow their classification into ability groups and support the a priori decision process on surgical interventions.

Predictors of quality of life outcomes in chronic rhinosinusitis after sinus surgery

The predictive value of olfaction for quality of life (QoL) recovery after endoscopic sinus surgery (ESS) in chronic rhinosinusitis (CRS) is still underestimated. The aim of this study was to explore the proportion of patients suffering from CRS who experience clinically significant QoL improvement after ESS and identify pre-operative clinical phenotypes that best predict surgical outcomes for QoL, focusing mainly on the role of patients' olfaction. One hundred eleven patients following ESS for CRS and 48 healthy subjects were studied. Olfactory function was expressed by the combined "Threshold Discrimination Identification" score using "Sniffin' sticks" test pre-treatment and 12 months after treatment. All subjects completed validated, widely used QoL questionnaires, specific for olfaction (Questionnaire of Olfactory Deficits: QOD), for assessing psychology (Beck Depression Inventory: BDI) and for general health (Short Form-36: SF-36). Statistically significant improvement of olfactory function by 41.8% and of all QoL questionnaires scores (all p < 0.001) was observed on the 12-month follow-up examination. Clinically significant improvement for QoL was measured in a proportion of 56.8% of patients on QOD, 64.9% on SF-36 and 49.5% on BDI scales results. Although olfactory dysfunction, nasal polyps, female gender, high socio-economic status and non-smoking habits were significantly associated with better QoL results, multivariate logistic regression analysis revealed that only olfactory dysfunction and nasal polyps were independent predictors significantly associated with higher likelihood of clinically significant improvement in all QoL questionnaire results. Olfactory dysfunction and nasal polyps were independent pre-operative predictors for surgical outcomes with regard to QoL results.

One year after endoscopic sinus surgery in polyposis: asthma, olfaction, and quality-of-life outcomes

OBJECTIVE

Nasal polyposis is a disease known to be associated with asthma. The long-term effects of surgical treatment on lower airways have not been sufficiently studied.

STUDY DESIGN

One-year follow-up of a double-blind, randomized, placebo-controlled study.

SETTING

The study was conducted at the Karolinska University Hospital, Stockholm, Sweden.

SUBJECTS AND METHODS

Fifty-one patients, age 18 years or older, with nasal polyposis and asthma were evaluated 1 year after endoscopic sinus surgery (ESS). Outcomes included dyspnea/cough scores, mean daily peak expiratory flow rate, spirometry, butanol test, olfaction scores, peak nasal inspiratory flow, polyp scores, and health-related quality of life (SF-36).

RESULTS

The short-term postsurgery improvements in asthma symptom scores, daily peak expiratory flow rate, all nasal parameters including olfaction, and quality-of-life scores were generally maintained 1 year after ESS.

CONCLUSION

Endoscopic sinus surgery had beneficial long-term effects on asthma, olfaction, and quality of life in patients with nasal polyposis. This is the first study to show long-term benefits of ESS on butanol tests in patients with nasal polyposis.

Does septoplasty enhance the quality of life in patients?

Evaluation of the severity of disease and the effectiveness of operative treatment is commonly done by registering pre- and postoperative symptoms. During the preceding decade, greater awareness has focused not only on the symptoms but also on patients' quality of life (QoL). The aim of the study was to determine the effect of septoplasty, as measured by generic and disease-specific QoL questionnaires. The generic 15D and disease-specific SNOT-22 questionnaires were given to patients before the operation and 6 months after the operation. Data analysis consisted originally of 188 septoplasty patients. One-hundred and twenty-six patients (67%) answered the SNOT-22 questions, and in the 15D, the response rate was 76%. In the post-operative SNOT-22, the need to blow the nose, sneezing, runny nose, nasal obstruction, loss of smell or taste, post-nasal discharge, facial pain/pressure, difficulty in falling asleep and waking up at night improved significantly. However in the 15D the mean QoL, i.e., general well-being, became significantly poorer. The QoL became increasingly poor especially in the older age groups and among the patients in which the improvement achieved in nasal symptoms postoperatively was minor. The more nasal symptoms the patients had pre- or postoperatively, the poorer the QoL was in general. Based on our results, critical evaluation of the symptoms and findings in the patients is essential in deciding whether surgery or other treatment should be given to individual patients having nasal blockage symptoms. Especially in patients with mild symptoms or among older patients, adequate medical treatment has to be tried before even considering surgery. The results also encourage the use of a systematic questionnaire to estimate the severity of symptoms in daily clinical practice.
