Un nouvel esprit du capital-risque spatial ? Sur quelques tendances récentes du financement de l’industrie spatiale américaine
Authors: Saint-Martin Arnaud
Published: June 2021

Le constat d’un basculement dans le financement des activités spatiales s’est imposé aux États-Unis depuis au moins une dizaine d’années. D’abord tâtonnant, puis de plus en plus substantiel, l’investissement issu du capital-risque a infléchi le cours du spatial privé. C’est même l’un des ressorts de ce qu’il est convenu d’appeler le New Space. Il ne s’agit pas seulement d’une source de financement qui en complèterait d’autres. L’introduction du capital-risque s’accompagne de la vulgarisation d’approches entrepreneuriales se voulant innovantes et audacieuses. La recherche des retours sur investissement les plus profitables est un objectif prioritaire, mais les créanciers du spatial « 2.0 » entendent influer directement sur le développement des start-ups qu’ils consentent à soutenir. Les fondateurs d’entreprises se revendiquant du « changement de paradigme » New Space emboîtent le pas et cherchent à persuader ces nouveaux soutiens que leurs promesses d’affaires sont crédibles. Cela ne fonctionne pas toujours, mais sur le marché des applications spatiales il se trouve toujours de possibles récits de réussite convertibles en dizaines de millions de dollars pour les investisseurs. Cette financiarisation du spatial n’est pas sans effets non plus sur l’establishment, à commencer par la NASA et les grandes firmes de l’aérospatiale. Des dispositifs de capital-risque sont ainsi créés par ces organisations. Si elle est encore marginale, l’importation de ces logiques n’est pas anecdotique et atteste la banalisation d’un modèle d’activité entrepreneurial jusqu’alors plus ou moins refoulé. Cet article propose d’objectiver et de mettre en perspective ces évolutions. À partir de données publiques et d’observations réalisées à l’occasion d’une recherche sur l’émergence du New Space aux États-Unis, on tentera de cerner les enjeux de l’affirmation de cette finance privée du spatial de « nouvelle génération », sans pour autant en conclure que ces tendances du capitalisme spatial sont inévitables ou nécessaires. Ce tableau se veut aussi une contribution à la critique de l’économie politique du spatial contemporain.

Authors: Lemay Louise , Marion Élodie , Jasmin Emmanuelle , Tougas Anne-Marie , Lessard Manon , Ricard Normand
Published: June 2021

L’implication de plusieurs acteurs est nécessaire pour répondre aux besoins multiples de jeunes souvent reconnus, dans le système scolaire québécois, en tant qu’Élèves handicapés ou en difficulté d’adaptation ou d’apprentissage (EHDAA). Or, la collaboration intersectorielle autour de la situation complexe de ces jeunes génère des défis et des tensions entre les partenaires. L’article rend compte de résultats issus d’une étude qualitative portant sur l’analyse des controverses, c’est-à-dire des positions divergentes des acteurs de l’éducation et de la santé et des services sociaux autour des situations de ces jeunes et de leur famille. Soixante-deux professionnels et gestionnaires œuvrant dans neuf régions du Québec (Canada) ont participé à l’étude. L’article expose les différents positionnements des acteurs au regard de situations relatives aux jeunes et aux parents.
La collaboration, une activité empêchée ?
Authors: Maillot Clémentine , Merini Corinne
Published: June 2021

Si la collaboration est souvent promue et poussée par des injonctions régulières, sa mise en œuvre n’est pas simple sur le terrain. La présente recherche vise à mieux comprendre la réalité professionnelle du travail collectif en situation d’intermétiers, en contexte scolaire. Nous étudions les mécanismes à l’œuvre et l’activité déployée par les professionnels dans ces situations. Les données ont été recueillies selon une méthodologie qualitative qui fait dialoguer les données récoltées à partir de trois outils : observation de séquences de négociation, autoconfrontation et questionnaire. Nos résultats font apparaître la collaboration comme une dynamique en tension, freinée par différentes catégories d’empêchements dont la régulation passe, à la fois par l’analyse des enjeux/contraintes en présence, la définition d’un outillage professionnel et la proposition de formations communes.
Postures des parents entendants d’enfant sourd au regard des services et des intervenants dans le domaine de la surdité
Authors: Kirsch Sarah , Piérart Geneviève , Gaucher Charles
Published: June 2021

La naissance d’un enfant présentant une surdité déstabilise le projet familial initialement prévu par les parents. Ils se retrouvent projetés dans un monde qui leur est inconnu et se sentent rapidement désorientés parmi les nouvelles terminologies, les nouvelles attentes et les nouvelles technologies qui font irruption dans leur vie. Les différents intervenants qui accompagnent les parents jouent un rôle prépondérant dans l’accès à l’information et dans l’acquisition d’un sentiment de compétence de la part des parents. Cet article, s’appuyant sur des données d’une recherche qualitative faite auprès de 117 parents d’enfant ayant une surdité dans différents pays francophones, s’intéresse aux postures des parents au regard des mesures de soutien et des professionnels.

Genèse de la politique d’intégration scolaire en France. Le rôle majeur d’Aimé Labregère (1925-1991)
Authors: Plaisance Éric , Vial Monique
Published: June 2021

Le mouvement de transformation de l’enseignement en France dans les années 1960 a des répercussions sur l’enseignement spécial, qui connaît alors un développement spectaculaire (classes spéciales, instituts médico-pédagogiques). De vives critiques sont énoncées contre les extensions sans limites du spécial et de ses effets de filière. Des évolutions se font jour au sein de l’Éducation nationale en faveur de mesures de prévention et d’adaptation au début des années 1970. Dans le prolongement de la loi de 1975 qui consacre le principe de l’éducabilité pour tous, les politiques d’intégration scolaire sont mises en place au début des années quatre-vingt. L’action d’Aimé Labregère se comprend dans ce contexte évolutif. Appelé en 1964 comme conseiller technique pour l’enfance inadaptée au ministère de l’Éducation nationale, il jouera un rôle majeur dans les mesures de prévention en 1970, dans la loi de 1975 et dans les politiques suivantes d’intégration scolaire. Le texte qui suit est une conférence prononcée dans l’académie du Calvados en 1984, où il présente, d’une manière originale, ses analyses sur l’intégration en fonction de son expérience internationale et de ses actions au sein de l’Éducation nationale.
Échiquier de la gouvernance : administrateurs indépendants et latitude discrétionnaire : cas des entreprises françaises

Published: June 2021

Nous abordons, dans le cadre de cette proposition, le poids des administrateurs indépendants sur la latitude discrétionnaire des managers, développée dans le cadre de l’activisme managérial. L’étude statistique menée sur les entreprises françaises, sur une période de 14 ans (2002 à 2015), montre que les administrateurs indépendants agissent défavorablement sur l’ancienneté du dirigeant dans son poste et renforcent le cumul qu’ils opèrent entre les mandats de manager et de président du conseil d’administration.
Obtenir un service de remplacement pour les objecteurs de conscience
Authors: Loustalot Arnaud
Published: June 2021

Au sein des organisations luttant pour la reconnaissance de l’objection de conscience en France, le Service civil international se distingue par sa volonté d’obtenir pour ces réfractaires la création d’un service civil en remplacement du service militaire. En organisant des chantiers internationaux de travail volontaire et des opérations de secours d’urgence, le SCI entend démontrer par l’exemple l’utilité sociale d’un tel service. Il se voit ainsi confier, avant même la reconnaissance officielle de ce service de remplacement, la gestion des premiers objecteurs une fois ces derniers désincarcérés. Luttant alors à leurs côtés pour l’obtention d’un statut acceptable, le SCI apparaît comme l’un des acteurs clés de la reconnaissance d’un droit fondamental.
Effect of conjugated protein composed of porcine myofibril and Protaetia brevitarsis protein on protein functionality
Authors: Kim T.-K. , Yong H.-I. , Sung J.-M. , Jang H.W. , Choi Y.-S.
Published: June 2021

The replacement of conventional protein supply has been studied in the context of continuous population growth and the consequent environmental problems. Among protein substitutes, edible insects have gained relevance due to their high breeding efficiency. This study was conducted to estimate the effect of the partial replacement of porcine myofibril protein (pork protein; PP) with protein extracted from Protaetia brevitarsis (insect protein; IP) in protein-containing solutions and gels. The protein concentration was regulated at 30 and 1 mg/ml for gels and solutions, respectively, and the replacement percentages were increased by 20%. Gels containing IP showed a lower viscosity and thermal stability; the texture and surface of the gels were negatively impacted as the replacement percentage increased. Therefore, heating is not an appropriate method to induce the gelation of IP containing solutions. However, the replacement of PP with IP increased the foam capacity and emulsion capacity in solutions. In conclusion, we show that the partial replacement of PP with IP positively impacts on protein solutions but impairs their gelation.
Extracting Wavefront Error From Shack-Hartmann Images Using Spatial Demodulation
Authors: Sarver Edwin J , Schwiegerling Jim , Applegate Raymond A
Published: June 2021

ABSTRACT

PURPOSE: To determine whether the spatial demodulation processing of Shack-Hartmann images is suitable for extracting wavefront gradients for ocular wavefront sensors.

METHODS: We developed a custom software program to implement the spatial demodulation technique. To test the algorithm's performance, we generated simulated spot images and obtained an eye examination image. We generated a collection of simulated aberrated spot images corresponding to: astigmatic wavefront (-5.00 -2.00 × 17), highly aberrated defocus (±20.00 diopters [D]), high-resolution defocus (-0.01 D), and third-order aberrations (trefoil and coma). The eye examination image and its measured Zernike coefficients were obtained from a Shack-Hartmann ocular aberrations system. We evaluated the output from the algorithm in terms of comparing the results to the known Zernike coefficients (for the simulated images) or the previously measured Zernike coefficients (for the eye examination image).

RESULTS: The spatial demodulation algorithm was able to correctly recover the aberrations to better than 1/100 (0.01) D for the simulated spot images. The processing of the eye examination image yielded results within approximately 1/4 (0.25) D to the values provided by the Shack-Hartmann system.

CONCLUSIONS: From the set of simulated images and the eye examination image used to test the spatial demodulation technique, it appears that the method is suitable for application in ocular wavefront aberrations Shack-Hartmann systems. The method appears capable of accurately processing high levels of aberrations (±20.00 D) as well as providing high resolution as evidenced by finding the -0.01 D defocus. The method may be especially well suited for processing highly aberrated wavefronts. [J Refract Surg. 2006;22:949-953.]

Authors: Kiziltan Anna
Published: June 2021

This chapter examines the nexus between population aging, international trade, foreign direct investment, and economic growth in the G20 countries over 1994-2018 by using the panel vector autoregressive analysis approach. The G20 countries are considered locomotives of the world economy. Moreover, the G20 countries are also be regarded as the center of concentration of the interconnection of the above factors in connection with their economic significance and the population size. Thus, the analysis carried out within the framework of this chapter allows a better understanding the nature of the relationship between the examined variables. Moreover, using the impulse-response functions and the variance decomposition method, both the individual response of the variables to the shocks and the overall effect's magnitude are revealed.
On the Socio-Economic Impacts of the Difference Between Healthy and Sick Aging
Authors: Caleiro António Bento
Published: June 2021

Population aging is a phenomenon that has characterized most countries in the world for many years now. Also, for some time now, the literature has shown some social and economic impacts of this phenomenon. This chapter intends to address an impact of a social nature, namely gender inequality, and an impact of an economic nature, namely the global burden of diseases, to which the literature on population aging has not yet given the necessary attention. For these impacts it is important to distinguish healthy aging from unhealthy aging. In fact, healthy aging not only reduces the global burden of disease but also contributes to a reduction in gender inequalities with regard to quality-adjusted years of life.

Authors: Anunciação Pedro Fernandes , Dinis Vitor Manuel Lemos , Esteves Francisco Madeira
Published: June 2021

Industry 4.0 marks the beginning of the so-called fourth industrial revolution. The new emerging information technologies, such as internet of things, cloud computing, machine learning, artificial intelligence, among others, have challenged the management and organization of industrial companies. They have now shorter market response times, higher quality requirements, and customization needs, which challenges many industrial areas from production to maintenance, from design to asset management. The maintenance and asset management condition and the reliability of production lines are closely linked and constitute key areas of good industrial operation. This work seeks to present a roadmap proposal for the management of industrial assets from maintenance management. In addition, it seeks to identify the key elements for a roadmap design and proposes a set of management questions to assess maintenance maturity.
Inequality in Early Childhood
Authors: Ali Dhouha Haj
Published: June 2021

This paper has a dual purpose. First, it aims to construct and evaluate parental investment in early childhood based on five indicators: mental development, discipline, nutrition, health, and leisure. Second, it aspires to establish a link between the education of mother and family well-being and the level of parental investment in early childhood with regard to the five indicators. The author tests the impact of family well-being and mother's education on investment in early childhood to find out if discrimination of gender and residence inequalities matter. Results indicate that the family's degree of wealth/socio-economic class and mother's education have a significant positive effect on all indicators of parental investment in early childhood except on discipline. The author also sees that households in rural areas invest more in the discipline of their children than urban ones. Moreover, they discriminate between gender in favor of boys.
A Hesitant Intuitionistic Fuzzy Set Approach to Study Ideals of Semirings
Authors: Mandal Debabrata
Published: June 2021

The classical set theory was extended by the theory of fuzzy set and its several generalizations, for example, intuitionistic fuzzy set, interval valued fuzzy set, cubic set, hesitant fuzzy set, soft set, neutrosophic set, etc. In this paper, the author has combined the concepts of intuitionistic fuzzy set and hesitant fuzzy set to study the ideal theory of semirings. After the introduction and the priliminary of the paper, in Section 3, the author has defined hesitant intuitionistic fuzzy ideals and studied several properities of it using the basic operations intersection, homomorphism and cartesian product. In Section 4, the author has also defined hesitant intuitionistic fuzzy bi-ideals and hesitant intuitionistic fuzzy quasi-ideals of a semiring and used these to find some characterizations of regular semiring. In that section, the author also has discussed some inter-relations between hesitant intuitionistic fuzzy ideals, hesitant intuitionistic fuzzy bi-ideals and hesitant intuitionistic fuzzy quasi-ideals, and obtained some of their related properties.

Power Allocation Adaptation With Coherence Time for Nonorthogonal Multiple Access on Downlink Transmission
Authors: Lin Jia-Chin , Liu Chih-Yen
Published: June 2021

Nonorthogonal multiple access (NOMA) methods are expected to improve spectral efficiency or increase sum rate in a recent mobile communication network. The performance of the power-domain NOMA highly relies on the effectiveness of successive interference cancelation (SIC) and power allocation techniques. This paper proposes an adaptive power allocation method according to analytical coherence time of time-varying channels to improve the SIC effectiveness. Simulations show that the proposed technique can improve SIC, therefore reducing error probability without reduction of the sum rate.
Conceptual Modeling of an IP Phone Communication System
Authors: Al-Fedaghi Sabah S. , Aldamkhi Ghadeer
Published: June 2021

In computing, a network generally denotes devices, often referred to as nodes, connected by links. Networks that are modeled with diagrams consist of hundreds of symbols, images, pictures, and icons, such as a computer, a server rack, or a cloud-based storage system. Network representations provide valuable insights into understanding the systems' underlying structures and mechanisms. Nevertheless, this unusually large number of superficial symbols and icons reflects a need for more systematic representations of the interiority of nodes. To give uniformity to this cascade of notions of basic units of nodes in network diagrams, the authors propose adoption of a new modeling methodology, called a thinging (abstract) machine (TM) (abstract machine of things) that represents all notions as a single diagrammatic machine. Because of the large number of network types, in this paper, they specifically and without loss of generality focus on IP telephone (internet protocol telephone) networks to exemplify communication networks. A real case study of IP telephone networks is modeled using TM.
COVID-19 Misinformation and Polarization on Twitter
Authors: Godard Rebecca , Holtzman Susan
Published: June 2021

This study investigated polarization on Twitter related to the COVID-19 pandemic by examining tweets containing #Plandemic (suggests the pandemic is a hoax) or #StayHome (encourages compliance with health recommendations). Over 35,000 tweets from over 25,000 users were collected in April 2020 and examined using sentiment and social network analyses. Compared to #StayHome tweets, #Plandemic tweets came from a more tightly connected network, were higher in negative emotional content, and could be sub-divided into specific categories of misinformation and conspiracy theories. To evaluate the stability of users' COVID-related perspectives, the prevalence of pro- and anti-mask sentiment was measured in same users' tweets approximately four months later. Results revealed substantial stability over time, with 40% of #Plandemic users tweeting anti-mask hashtags compared to just 2% of #StayHome users. Findings demonstrate COVID-related polarization on Twitter and have implications for public health interventions to quell the propagation of misinformation.

Published: June 2021

This study uses a content analysis method to systematically review 83 research papers from 2002-2018 to explore consumer-to-consumer (C2C) e-commerce research trends. The findings of this study indicate that (1) C2C e-commerce is discussed and investigated in many disciplines, but mainly published in e-commerce journals; (2) studies on C2C e-commerce increasingly focus on diverse topics, but concentrate on regions such as China and the United States; (3) the focus of academic collaboration has shifted from domestic to international collaboration, and collaboration within the same institution. However, collaboration is scarce across different study teams; (4) the data-driven approach is the main approach used in studies on C2C e-commerce; (5) while the number of recent C2C e-commerce studies adopted theories is increasing, few have developed theoretical frameworks or models. Finally, study implications and future study suggestions are also discussed.
Deep Neural Network and Time Series Approach for Finance Systems
Authors: Srivastava Praveen Ranjan , Zuopeng (Justin) Zhang  , Eachempati Prajwal
Published: June 2021

The stock market is an aggregation of investor sentiment that affects daily changes in stock prices. Investor sentiment remained a mystery and challenge over time, inviting researchers to comprehend the market trends. The entry of behavioral scientists in and around the 1980s brought in the market trading's human dimensions. Shortly after that, due to the digitization of exchanges, the mix of traders changed as institutional traders started using algorithmic trading (AT) on computers. Nevertheless, the effects of investor sentiment did not disappear and continued to intrigue market researchers. Though market sentiment plays a significant role in timing investment decisions, classical finance models largely ignored the role of investor sentiment in asset pricing. For knowing if the market price is value-driven, the investor would isolate components of irrationality from the price, as reflected in the sentiment. Investor sentiment is an expression of irrational expectations of a stock's risk-return profile that is not justified by available information. In this context, the paper aims to predict the next-day trend in the index prices for the centralized Indian National Stock Exchange (NSE) deploying machine learning algorithms like support vector machine, random forest, gradient boosting, and deep neural networks. The training set is historical NSE closing price data from June 1st, 2013-June 30th, 2020. Additionally, the authors factor technical indicators like moving average (MA), moving average convergence-divergence (MACD), K (%) oscillator and corresponding three days moving average D (%), relative strength indicator (RSI) value, and the LW (R%) indicator for the same period. The predictive power of deep neural networks over other machine learning techniques is established in the paper, demonstrating the future scope of deep learning in multi-parameter time series prediction.
An Empirical Examination of the Relationship Between Data Storytelling Competency and Business Performance
Authors: Daradkeh Mohammad Kamel
Published: June 2021

With the proliferation of big data and business analytics practices, data storytelling has gained increasing importance as an effective means for communicating analytical insights to the target audience to support decision-making and improve business performance. However, there is a limited empirical understanding of the relationship between data storytelling competency, decision-making quality, and business performance. Drawing on the resource-based view (RBV), this study develops and validates the concept of data storytelling competency as a multidimensional construct consisting of data quality, story quality, storytelling tool quality, storyteller skills, and storyteller domain knowledge. It also develops a mediation model to examine the relationship between data storytelling competency and business performance, and whether this relationship is mediated by decision-making quality. Based on an empirical analysis of data collected from business analytics practitioners, the results of this study reveal that the data storytelling competency is positively linked to business performance, which is partially mediated by decision-making quality. These results provide a theoretical basis for further investigation of possible antecedents and consequences of data storytelling competency. They also offer guidance for practitioners on how to leverage data storytelling capabilities in business analytics practices to improve decision-making and business performance.

Cloud computing is an optimistic technology that leverages the computing resources to offer globally better and more efficient services than the collection of individual use of internet resources. Due to the heterogeneous and high dynamic nature of resources, failure during resource allocation is a key risk in cloud. Such resource failures lead to delay in tasks execution and have adverse impacts in achieving quality of service (QoS). This paper proposes an effective and adaptive fault tolerant scheduling approach in an effort to facilitate error free task scheduling. The proposed method considers the most impactful parameters such as failure rate and current workload of the resources for optimal QoS. The suggested approach is validated using the CloudSim toolkit based on the commonly used metrics including the resource utilization, average execution time, makespan, throughput, and success rate. Empirical results prove that the suggested approach is more efficient than the benchmark techniques in terms of load balancing and fault tolerance.

Published: June 2021

Introduction

Known as the “great mimic,” pheochromocytoma is rare and difficult to diagnose. When a pheochromocytoma begins to cause end-organ damage, it becomes pheochromocytoma multisystem crisis, an even more rare and deadly diagnosis.

Clinical Findings

N.R., a 63-year old man, presented to the emergency department 1 day after receiving a cortisone injection for a nondisplaced wrist fracture. His chief concern was a “racing heart and chest pressure.” N.R. was admitted to the telemetry unit after routine electrocardiography showed atrial fibrillation and elevated blood pressure. Symptoms quickly progressed, and N.R. was transferred to the intensive care unit where he received noninvasive positive pressure ventilation.

Diagnosis

A computed tomography scan revealed a 7-cm right intra-adrenal mass, and an echocardiogram showed a markedly reduced ejection fraction. N.R. received a preliminary diagnosis of pheochromocytoma multisystem crisis, although confirmatory laboratory test results were pending. N.R. became progressively more hemodynamically unstable and his respiratory status worsened, and by the end of hospital day 2 he had been intubated and was receiving multiple vasoactive medications intravenously. On hospital day 7, N.R. was transferred to a facility for definitive surgical intervention.

Conclusion

This case represents the importance of timely interventions by nursing staff, clear communication between staff on different shifts, and real-time education by physicians to nursing staff. This collaborative milieu empowered nurses to use their experience and critical thinking to make clinical decisions in providing care.
The Correlation between Sleep Quality and the Prevalence of Obesity in School-Age Children

Published: June 2021

Background

The prevalence of obesity increases year by year. Sleep quality is considered to be one of the obesity causes. The current average sleep range of children in Indonesia was 6-7 hours. This study aims to analyze whether the sleep quality affects the prevalence of obesity in children.

Design and methods

This study used prospective cohort as the research method. The samples consisted of 37 primary schoolage children (4th-6th grade) from West Java and Sumatra. The respondents were selected using snowball sampling technique due to pandemic situation during data collection period. The data were collected by using PSQI and sleep logs (within a month).

Results

The statistical results show that there were 19 obese and 18 non-obese children. Fourteen out of 19 obese children were boys, while among not obese children, the number of boys and girls were similar. Twelve out of 19 obese children had poor sleep quality (63.2%), while most of the non-obese children had good sleep quality (83.3%). Based on the chi-square statistic, the pvalue = 0.011 < (0.05) indicating that H0 was rejected, which means there was a correlation between sleep quality and obesity, with OR=8.571 (95% CI: 1.818-40.423). In another words, the children with poor sleep quality were likely to experience obesity 8.6 times greater than those who had good sleep quality.

Conclusions

This study found there were correlations between dietary intake, physical activity, sleep quality, and obesity in school-age children. The most dominant factor related to obesity in school-age children is the habitual sleep efficiency (OR=12.354).

Background

Adherence to self-care is the goal of nursing care for elderly people with hypertension to give them optimal functional health status. The purpose of this paper is to determine the effectiveness of self-management on adherence to self-care and management of health status elderly people living with hypertension in Pekanbaru City.

Design and methods

This study design was quasi-experimental with a pre-post test with a control group. The self-management intervention was provided through four home visits to elderly people living with hypertension with a caregiver. Samples were taken by the consecutive sampling technique, and a total number 134 elderly people were participants. The instruments used were the adherence to self-care questionnaire and the Short Form 12 Health Survey (SF12) for elderly people.

Results

The results showed that most of the respondents with hypertension were 60-74 years of age (84.3%), were female (67.9%), of Minang ethnicity (48.5%), had completed primary school (44%), were unemployed (81.3) %), had a family history of hypertension (50%), were non-smokers (52.2%), and had never drunk alcohol (95.5%). The effects of self-management were positive on adherence to caring for themselves (p<0.001) and on health status (p<0.001). The most influencing factor on self-care compliance and health status after being controlled by confounding variables was self-management (p<0.001).

Conclusions

This study recommends that nursing interventions on self-management for elderly people with hypertension in the community and should be integrated into the Community Health Nurses’ (Perkesmas) program in Indonesia.

Published: June 2021

Background: Loss of sense of smell is one of the most frequent complaints in patients with nasal polyposis (NP). The aim of this study was to evaluate the impact of asthma and its severity on the sense of smell. Material and methods: Patients with massive NP and healthy controls were included. More than half of patients presented with asthma. Olfactometry by Barcelona Smell Test 24, nasal symptoms score, nasal endoscopy, allergy study, and paranasal sinus CT scan were assessed. Results: NP patients showed a significant impairment in smell detection, identification, and forced choice compared to the control. Asthmatics reported lower scores for detection, identification, and forced choice than non-asthmatic patients. Patients with persistent asthma had an increased impairment of sense of smell on detection, identification, and forced choice than patients with intermittent asthma. No significant differences were found between mild, moderate, and severe persistent asthmatics. Paranasal sinuses opacification was inversely correlated with smell detection, identification and forced choice. Conclusion: These findings suggest that patients with NP have an impaired sense of smell, that asthma -particularly persistent asthma- has a further impact on sense of smell, and that loss of smell may be used as a clinical tool to identify the severity of both NP and asthma.
Visual analogue scale assessment of nasal obstruction might define patients candidates to spirometry

Published: June 2021

Background: Asthma may be frequently associated with allergic rhinitis. Bronchial obstruction is a characteristic of asthma and spirometry is a cardinal step in asthma diagnosis. However, spirometry is rarely suitable in medical office. Visual Analogue Scales (VAS) is frequently used in common practice. Objective: This study aimed at evaluating the suitability of the use of VAS assessment of nasal obstruction to define patients with allergic rhinitis candidates for spirometry. Methods: 1728 patients with allergic rhinitis were consecutively evaluated. Clinical examination, skin prick test, VAS assessment, and spirometry were performed in all patients. Results: 7.9% of patients had impaired FEV1 values and 24.5% had impaired FEF25-75 values. A VAS value < 3.3 might identify with good reliability patients with impaired FEF25-75 values, such as having initial bronchial airflow limitation. Conclusions: This study, performed in a large cohort of subjects, highlights the close link between upper and lower airways and shows the possible suitability of the use of nasal obstruction VAS assessment to define patients with allergic rhinitis candidates for spirometry.
