Published: August 2022

ABSTRACT Objective: The aim of this study was to perform a narrative review of the leading pediatric triage systems in emergency departments (EDs). Data source: Articles published between 1999 and 2019 were identified by searching the MEDLINE, EMBASE, and PubMed databases using the keywords “pediatric triage”, “pediatric assessment tools”, and “emergency department triage” with an emphasis on studies that evaluated the validation and reliability of triage systems. Data synthesis: A total of 105 articles on pediatric emergency triage systems in 12 countries were evaluated. Triage systems were divided into two groups: color-stratified triage systems and alert systems. The color-stratified triage systems included in this review were the Canadian Triage and Acuity Scale (CTAS), Manchester Triage System (MTS), Emergency Severity Index (ESI), and Australasian Triage Scale (ATS), and the alert systems included were the Paediatric Observation Priority Score (POPS), Pediatric Early Warning Score (PEWS), and Pediatric Approach Triangle (PAT). Evidence corroborates the validity and reliability of MTS, PaedCTAS, ESI version 4, PEWS, POPS, and PAT in pediatric emergency services. Conclusions: These are fundamental tools for risk classification of patients seeking treatment in EDs. Not all triage systems have been assessed for validity and reliability; nor are they well suited for all regions of the world. Employing triage systems in Brazil requires cultural adaptation and rigorous training of the local health staff, in addition to validation and reliability studies in our country, since the social and cultural context of this country differs from those where these tools were developed.

Significance Statement

Acquired nephrogenic diabetes insipidus (NDI), a common polyuric disorder, is caused by the loss of aquaporin-2 (AQP2), but early mediating molecular events remain unclear. Our previous study of lithium-induced NDI showed NF-κB signaling and an inflammatory-like response that represses Aqp2 transcription. Here, we investigate early signaling responses triggered by unilateral ureteral obstruction (UUO) using small-sample RNA-Seq of microdissected rat renal cortical collecting ducts. Early global mRNA suppression followed by an inflammatory signaling response explains loss of AQP2 after UUO. Activation of inflammatory-like signaling may be a shared property of acquired NDI syndromes that leads to repression of Aqp2 gene expression.

Background

Ureteral obstruction is marked by disappearance of the vasopressin-dependent water channel aquaporin-2 (AQP2) in the renal collecting duct and polyuria upon reversal. Most studies of unilateral ureteral obstruction (UUO) models have examined late time points, obscuring the early signals that trigger loss of AQP2.

Methods

We performed RNA-Seq on microdissected rat cortical collecting ducts (CCDs) to identify early signaling pathways after establishment of UUO.

Results

Vasopressin V2 receptor (AVPR2) mRNA was decreased 3 hours after UUO, identifying one cause of AQP2 loss. Collecting duct principal cell differentiation markers were lost, including many not regulated by vasopressin. Immediate early genes in CCDs were widely induced 3 hours after UUO, including Myc, Atf3, and Fos (confirmed at the protein level). Simultaneously, expression of NF-κB signaling response genes known to repress Aqp2 increased. RNA-Seq for CCDs at an even earlier time point (30 minutes) showed widespread mRNA loss, indicating a “stunned” profile. Immunocytochemical labeling of markers of mRNA-degrading P-bodies DDX6 and 4E-T indicated an increase in P-body formation within 30 minutes.

Conclusions

Immediately after establishment of UUO, collecting ducts manifest a stunned state with broad disappearance of mRNAs. Within 3 hours, there is upregulation of immediate early and inflammatory genes and disappearance of the V2 vasopressin receptor, resulting in loss of AQP2 (confirmed by lipopolysaccharide administration). The inflammatory response seen rapidly after UUO establishment may be relevant to both UUO-induced polyuria and long-term development of fibrosis in UUO kidneys.

Published: August 2022

The extensive use of chemical insecticides to control mosquitoes led to the development of insecticide resistance and environmental health hazards. This caused a surge in interest in eco-friendly biocontrol agents. The present study aimed to explore the susceptibility of different instar larvae of the common mosquito, Culex pipiens Linnaeus, 1758, to the mermithid nematode, Romanomermis iyengari Welch, 1964. Moreover, the effects of R. iyengari on the mosquito pupal developmental time, adult emergence, longevity, female fecundity, as well as egg-hatching rate were determined after larval treatment with an LC50 quantity of the nematode pre-parasites. Different instars of Cx. pipiens (1st–4th) were exposed separately to R. iyengari at concentrations of 1–6 pre-parasites/mosquito larva. Mortality rates of mosquito larvae were observed and the LC50 values were calculated. The estimated LC50 values for the 1st–4th larval instars were 3.18, 2.73, 3.79 and 4 pre-parasites/larva, respectively. Mean percent mortality of the 1st–4th larval instars ranged from 10–94%, 16–100%, 4–100% and 0–52%, respectively. The results indicated that exposure of 4th larval instar to the LC50 of R. iyengari pre-parasites significantly prolonged the duration of pupal development, reduced the percentage of emerged adults and reduced mosquito female fecundity compared with the control. In contrast, adult longevity and the egg-hatching rate did not differ between the control and the exposed group. In conclusion, this isolate of R. iyengari could be a promising biocontrol agent for Egyptian Cx. pipiens. Other trials are required to assess the biocontrol potential of this parasite in field conditions.

FOREIGN DIRECT INVESTMENTS IN DEVELOPING COUNTRIES
Authors: Ucar Onur Fahri , Tuncay Ozhan
Published: August 2022

Purpose- The purpose of this study is to study is to determine the possible determinants of foreign direct investment in 10 emerging economies (Argentina, Brazil, Chile, Colombia, Egypt, Indonesia, India, Mexico, South Africa, Turkey) that have current account deficit and need foreign direct investment for the period between 2010-19. An empirical model was created with the help of macro variables such as inflation rate, nominal exchange rate, trade openness, market size, interest rate and annual electricity consumption representing the development of infrastructure for 10 developing countries' economies..
Methodology- In this study, data were collected through Worldbank database.The study employs Feasible Generalized Least Squares (FGLS) method for analysis.
Findings- The analysis reveals that ; infrastructure, exchange rate and trade openness variables were found to be highly significant and explain the dependent variable. It has been observed that there is an inverse relationship between the market size, interest rate and trade openness variables and foreign direct investments, which is considered as dependent variable. On the other hand, it has been determined that there is a positive relationship between the infrastructure, exchange rate variables and the dependent variable.
Conclusion- - Based upon the analyisis findings it may be concluded that; the development of the infrastructure level in the countries discussed will encourage direct investments as it will increase the profitability of the companies that will invest.
An increase in the exchange rate will also make domestic firms cheaper and encourage direct investments through acquisitions. However, excessive fluctuations in exchange rates may adversely affect direct investments due to the uncertainty it will cause on the expected return of the investment. Considering the negative relationship between trade openness and direct investments, it can be thought that the increase in the degree of openness to foreign trade in the relevant countries will direct foreign companies to export their products instead of establishing facilities in the relevant countries. Since the 1980s, both the developments in communication technology and the adoption of more liberal economic policies by countries have led to an increase in capital flows between countries. As a more reliable source against the financial crisis risk borne by short-term capital flows, foreign direct investments play an important role in meeting the need for foreign exchange and capital accumulation, especially in developing countries. Therefore, it is important for the relevant countries to solve macroeconomic problems such as insufficient infrastructure, exchange rate instability and create a stable investment environment in order to increase direct investment inflows..

WORKPLACE HUMOR: ANTECEDENTS AND CONSQUENCES
Authors: Muceldili Busra
Published: August 2022

Purpose-In the last three years, individuals have been faced with many challenging events that will make them feel negative. Pandemics, economic crises and wars affect the daily lives of individuals as well as their business lives. In addition, employees state that they work under high pressure and often feel unhappy. Studies show that positive emotions and situations have positive outcomes such as employee performance and organizational citizenship behavior. In this context, employees need factors that will increase their positive emotions and situations. Although humor is an unusual concept for workplaces that are considered serious by nature, it has recently attracted the attention of both managers and academics. The purpose of this research is to examine the antecedents and consequences of humor in the workplace.
Methodology- In this study, quantitative and qualitative methods will be used together. First, a qualitative research will be conducted and employees will be asked what they understand from humor in the workplace. Then, content analysis will be made and common themes will be revealed. In the second stage, a survey will be conducted with the existing scales in the literature.
Findings- In the research, firstly, white-collar and 5 years of work experience were asked to define the concept of humor in the workplace, then they were asked what their suggestions were to improve humor, and finally, they were asked what positive outcomes they had on the days when they felt the sense of humor.
Conclusion- As a result of this study, humor in the workplace in Turkey has been examined. After the qualitative part of the research, study two, which is the quantitative part, will be started. After the concept of humor is defined by Turkish employees, the proposed research model will be tested in the light of organizational behaviour and management literature. In the research model, playful work design is suggested as the premise of the sense of humor, and creativity and knowledge sharing as its output. Questionnaire method will be used to test the research model. The research model will be tested using structural equation modeling.

Keywords: Humor,organizational culture, knowledge sharing, creativity, playfulness, work design.

Self-concept of EFL preservice teachers as reflected in their teaching performance
Authors: Rachmawati Dina
Published: August 2022

A number of studies discussing the significant role of self-concept in the educational field are evident.  However, research investigating the self-concept of English as a Foreign Language (EFL) preservice teachers and how the self-concept is reflected in the teaching performance is limited. Thus, this study was aimed at investigating the portrait of the self-concept of English preservice teachers in the Indonesian context and how the self-concept is reflected in their teaching performance. A qualitative research paradigm, especially an explanatory case study design was employed to figure them out. The study found that first, diverse portraits of self-concept i.e. highly positive, moderate, and low or negative self-concept were captured in the participants’ academic self-concept (pedagogic and professional self-concept) with the inclination of higher portrayal in the non-academic sub-aspects of self-concept (social and emotional self-concept). Second, the congruent and incongruent reflection of self-concept were identified. The findings imply that academic aspects of self-concept (pedagogic and professional competence) seem to be contributing factors to the participants’ negative self-perception of their self-concept. Moreover, reflexivity, internal and external frames of reference, and emotion regulation strategies seem to be contributing factors to the construction of the participants’ self-concept. This study concludes that the construction of the participants’ self-concept dynamic during the practicum and its manifestation in the teaching performance is affected by internal and external factors.
Evidence-Based Planning: A Multi-Criteria Index for Identifying Vacant Properties in Large Urban Centres
Authors: Jacovine Thiago Corrêa , Nogueira Kaio , Fernandes Camila Nastari , Da Silva Gabriel Marques
Published: August 2022

Attempts to avoid property vacancy represent an immense challenge for local authorities and planning policy design. Despite recent normative and regulatory advances witnessed in the recent past with the recognition of the social function of the property by the federal constitution (1988) and statutory instruments included in the city statute (2001) and local master plans, Brazilian cities still experience difficulty in producing evidence-based indicators to support the implementation of progressive planning policies. This article offers a methodological approach using a multi-criteria index to identify vacancy propensity levels in the central area of São Paulo. The research results from a partnership between the municipal authority and two planning laboratories from public universities and financial support from UNESCO. The index was designed using a multi-criteria decision aid technique, PROMETHEE II. The proposed methodology involved the manipulation of eight variables related to the vacancy phenomenon and a two-phased validation process: one quantitative using statistical tests and the second qualitative through the scrutiny of the index by urban specialists. The result represents the potential vacancy levels for 3,254 urban blocks and their spatial distribution. For the 344 blocks inspected through fieldwork, 619 potential vacant properties were identified. The development and analysis of the index show that this approach provides valuable information on vacancy levels accounting for its spatial distribution. The index is a flexible tool that can absorb particular local conditions and support evidence-based policy-making.

Published: August 2022

The necessity and relevance of the study of the experience of formation and implementation of anti-corruption policy in the EU member states in order to implement it in Ukraine, due to its European integration vector of development is substantiated. The essence and causes of corruption depending on the spheres of society, as well as the characteristics of corruption in Ukraine and its impact on the economic and social parameters of the country, resulting in lower living standards. The existing models of perception of corruption in the world and the main strategies of anti-corruption activity are described. It is proved that the choice of strategy and model of anti-corruption activities in each country depends on many factors, and Ukraine's European integration course requires harmonization of national anti-corruption legislation with EU standards. The main causes of corruption in EU member states and features of anti-corruption policy of some European countries are analyzed. It has been shown that corruption is more or less common to almost all EU countries, however, common to all countries in terms of formation and implementation of anti-corruption policy is that it aims to minimize opportunities for corruption offenses. It is established that the basis of the anti-corruption policy of the Scandinavian EU member states is the concept of public administration "Good Governance", which combines institutions, processes and mechanisms through which citizens express their interests and exercise legal rights. It was found that EU countries do not pursue a common anti-corruption policy, and each country develops its own anti-corruption infrastructure, which aims to minimize opportunities for corruption offenses. It is proved that the insufficient effectiveness of the mechanisms of the state anti-corruption policy makes it impossible to carry out structural reforms on the way to full membership of Ukraine in the EU. Priority areas for further formation and implementation of anti-corruption policy in Ukraine have been identified, taking into account European integration aspirations and existing international standards.

Authors:   Taras Shevchenko National University of Kyiv, Nelipa Dmytro
Published: August 2022

Today, digitalization has taken over almost all spheres of public life. The pandemic and the transition to an online format in work and study has significantly intensified the processes of technologicalization. The work of the civil service in Ukraine is no exception. The introduction of new technologies has opened up a number of new opportunities that have made the provision of public services even faster, more convenient and safer, thanks to compliance with quarantine regulations. However, the rapid development of technology has led to a shortage of staff who could work effectively with these technologies. And, if in big cities the situation needs additional training of specialists, then in remote settlements the lack of specialists is felt much more. The article theoretically substantiates the impact of digitalization processes on the development of civil service in Ukraine, identifies the main problematic aspects of the introduction of electronic services in this area and the need to develop training and retraining of civil servants in accordance with the challenges of the time. As a result of a thorough analysis of scientific and journalistic sources, as well as official government electronic portals, it was found that today the transfer of all public services in electronic format and the use of new technologies to maximize the efficiency of public services is a key vector of modern Ukrainian public service. services. However, the lack of qualified personnel who would be able to master these technologies has become a significant obstacle to digitalization processes. This is especially noticeable in local governments. Therefore, the formation of a system of professional training of relevant personnel today is more important than ever. The study analyzed the Ukrainian experience of implementing electronic services through the system of public services, highlighted the current obstacles to their further development and identified a number of recommendations for improving the system of appropriate training.

Published: August 2022

In this work, we study the issues of a constructive stochastic integral representation of Brownian functionals, which are interesting from the point of view of their practical application in the problem of hedging a European option. In addition to briefly discussing known results in this direction, in the case of stochastically smooth (in Malliavin sense) functionals, we also illustrate the usefulness of the Glonti–Purtukhia representation for non-smooth functionals. In particular, we generalize the Clarke–Ocone formula to the case when the functional is not stochastically smooth, but its conditional mathematical expectation is stochastically differentiable, and find an explicit expression for the integrand. Moreover, we consider such functionals that do not satisfy even weakened conditions, that is, non-smooth, past-dependent Brownian functionals, the conditional mathematical expectations of which are also not stochastically differentiable, and again we give a constructive martingale representation.
Role of media information in managing mass emotions in social communications of modern Ukraine (a brief overview as a statement of the question)
Authors:   Taras Shevchenko National University of Kyiv, Demutska Alevtyna
Published: August 2022

The study's main objective is to prove the presence of practical attempts in managing the third component of the mass communication message in modern Ukrainian social communications. It is the mass-emotional component. In previous studies, the author proved that the nature of social communications in the modern digital society is based on the unity of mass information, mass interpretation, and mass emotions. Therefore, it is essential to find actual attempts on the part of the organizers of certain political discourses to manage mass emotions in social communications with the help of the media. The main conclusion of the study is that the scientific assumption regarding the presence of attempts to manage mass emotions through audiovisual and digital domestic media in social communications was confirmed. However, it is vital for further investigations of the scientific problem of how to manage the mass emotions functioning in social communications. The methods used during the research to achieve the goal were content monitoring, comparison, generalization, and analysis of texts.

Copper is widely used and therefore it is a pollutant metal. It is important to develop probes that can selectively determine copper with high sensitivity. The benzoaza-15-crown-5 derivatives are used as fluorescence sensing systems and excellent spectroscopic properties are demonstrated. The “N”, “O” atoms of the heterocyclic unit act as binding sites for recognizing copper ions. A new, simple, sensitive fluorescence method for the determination of Cu2+ ions was developed and analytical characteristics of the proposed probe were estimated. The Cu2+ ions can significantly quench the fluorescence intensity of N-(2-carboxymethyl)benzoaza-15-crown-5 (Cr) in ethanol/H2O (4:6, v/v) solvent mix containing urotropine buffer (pH 7.5) at λex = 274 nm and λem = 308 nm. The probe has high photostability. Under optimal conditions, the quenching of fluorescence intensity depends on the concentration of Cu2+ ions in the range of 1.70 × 10-6 - 2.38 × 10-4 М, detection limit was 0.56 μМ. This method was applied for the determination of Cu2+ ions in drinking water. The quenching effect in the presence of copper (II) can be explained by the termination of intramolecular charge transfer from the chelate center to the aromatic part of the molecule due to chelation.
Implementation of Multi-Level Bidirectional Inter Allied Converter Community for Global Power Sharing in Hybrid AC/DC Microgrids
Authors: Pabbuleti Bhavana , Somlal Jarupula
Published: August 2022

Bidirectional Inter-Allied Converters (BIACs) plays a major role in hybrid ac-dc microgrids (HM) forming as a bridging unit for power exchange between ac and dc subgrids. Overcoming the stress faced by single BIAC multiple converter structure i.e BIAC community came into existence. Considering advantages over two-level converters, multi-level converters sustain its position in today and future applications. Implementing the multi-level converter topology for distributed power management enhances the system efficiency with less amount of harmonic content. This paper presents implementation of Multi Level Bidirectional Inter Allied Converter (MLBIAC) community along with the Localized Distributed Proportional Integral Controller (LDPIC) located at each converter in HM for distributed power management. The localized distribution controller includes PI controller for system stability and which allows exchanging the information in more flexible way. To achieve the global power sharing by implementing MLBIAC in HM, the concepts like balanced power sharing, leading role transition, bidirectional power flow, system stability were analyzed and simulated using MATLAB/Simulink software.

Published: August 2022

The Circle Diagram was used in past for the performance evaluation of 3-phase induction motor under different load conditions. But, now it is not preferred due to availability of programs for detailed analysis. The per-phase equivalent circuit is also not that suitable to estimate the dynamic performance. In this paper, a method is suggested to determine the performance using dq-model.  The objective of this paper is to describe modelling in terms of dq variables. The analysis under steady state condition is done using numerical technique tools. The numerical tools such as Gauss-Seidel and Successive Relaxation methods are used and the results are compared with that obtained from the experiment conducted in the laboratory. The comparison of results confirms the validity as well as the accuracy of the proposed methods, as yet another approach to predetermine the performance.

The problem of studying the goals, objectives and legal mechanisms for the implementation of the Environmental Doctrine of the Russian Federation and the development of the doctrine of environmental law in the absence of a clear systematization and interconnection of a set of strategic planning documents is very relevant.

The article summarizes and analyzes the main provisions of the Environmental Doctrine of Russia. The authors show that economic globalization significantly changes the nature of environmental management. Many environmental phenomena and related social relations are of a national, international nature.

The authors of the article investigated the issues of strategic understanding of international and national environmental policy. The necessity of forming the doctrine of environmental law is shown.

The authors believe that the current trends in the development of international relations and the national characteristics of Russia, its competitive advantages, as well as the challenges it faces internally and externally, require the development and implementation of a new environmental policy, its transformation into one of the national and foreign policy priorities. The authors substantiate the necessity and possibility of revising the current environmental and legal national regulation. The ideological and organizational-legal features of the preparation of a new environmental doctrine and the doctrine of environmental law are shown.

The article is aimed at the development of ecological and legal mechanisms of environmental protection in the conditions of economic sanctions in order to develop a balanced state environmental policy in the new economic and political conditions of socio-economic development of Russia.

Authors: Zinoveva O. A.
Published: August 2022

The article deals with the following issues: decarbonization; experiment on emissions quotas for pollutants conducted in some cities of the Russian Federation and the experiment planned to be conducted in some subjects of the Russian Federation; limitation of greenhouse gas emissions; atmospheric air protection; atmospheric air quality standards as well as standards for emissions of harmful (polluting) substances into the air and harmful physical impacts on it. In addition, the significance of such natural resource as forest, which is the main natural absorber of greenhouse gases in terrestrial ecosystems, and carbon polygons — one of the ways to study and control the global environmental problem of climate change on the planet — is shown.
Economic Measures to Limit Greenhouse Gas Emissions: A Comparative Legal Context
Authors: Krasnova I. O.
Published: August 2022

The article gives an assessment and, in a comparative legal context, analyzes the emerging Russian legislation aimed at reducing greenhouse gas emissions. The carbon regulation system is based on the introduction of an innovative for environmental law procedure for trading greenhouse gas emissions. The review and analysis of international agreements on climate is given. It is concluded that the current agreements do not prescribe the introduction of a legal mechanism for trading in carbon units, since the Kyoto Protocol has not been in force with respect to Russia since 2012. The main influence on the development of domestic legislation is exerted by the climate legislation of the European Union. Comparisons of recent federal emission control laws show some discrepancies with the EU. Criticisms are expressed that create risks of reducing the effectiveness of laws, and proposals are made on the integration of legal measures to limit emissions into the general legal model of environmental protection.

Introduction: Most of avoidable defibrillator therapies can be reduced by evidence-based programming, but defining tachycardia configurations across all device manufacturers is not straightforward. Aims: To determine if a uniform programming of tachycardia zones, independently of the manufacturer, result in a lower rate of avoidable shocks in primary-prevention heart failure (HF) patients and also if programming high-rate or delayed therapies can have some benefit. Methods: Prospective cohort with historical controls. HF patients with a primary-prevention indication for a defibrillator were randomized to receive one of two new programming configurations (high-rate or delayed therapies). A historical cohort of patients with conventional programming was analyzed for comparison. The primary endpoint was any therapy [shock or anti-tachycardia pacing (ATP)] delivered. Secondary endpoints were appropriate shocks, appropriate ATP, appropriate therapies, inappropriate shocks, syncope and death. Results: 89 patients were assigned for new programming group [high rate (n=47) or delayed therapy (n=42)]. They were compared with 94 historical patients with conventional programming. During a mean follow-up of 20±7 months, the new programming was associated with a reduction in any therapy (HR = 0.265, 95% CI 0.121-0.577, p=0.001), even after adjustment. Aproppriate ATP and any shock were also reduced. Syncope did not occur. Sudden, cardiovascular and all-cause deaths were not different between the groups. In the new programming group, neither highrate nor delayed programming were better than the other. Conclusions: In our study, programming tachycardia zones homogeneously across all manufacturers was possible and resulted in a lower rate of therapies, shocks and appropriate ATP.

Objective: The protective effect of the Mediterranean diet (MD) is known for several diseases, but the evidence in low- and middle-income countries was still missing. This article assesses the impact of MD and its components on Chronic Obstructive Pulmonary Disease (COPD) among Moroccan adults. Methods: in population-based cross-sectional study, A total of 744 adults with acceptable spirometry according to the GOLD guidelines were randomly selected from a sample frame, of Moroccan adults lived in the areas of the Saïs district-Fez city. Dietary data were collected through a validated food frequency questionnaire. Mediterranean Diet Score (MDS) was used to assess Adherence to the Mediterranean food model, A value of 0 or 1 has been assigned to each of the eight indicated food components according to their beneficial or deleterious effect on health. Results: Although no significant associations were found between COPD and the overall MD. score, associations were found between some of the MD components and COPD when stratifying for overall MDS adherence level (low, middle, high adherence). For the high adherence group, the high consumption of cereals, fruits and nuts were inversely associated with COPD risk with OR = 0.64; 95% CI = 0.26-0.89, and OR= 0.67; 95% CI = 0.44-0.96, respectively. The high consumption of meats and dairy products was positively associated with the risk of COPD, with OR = 1.37; 95% CI = 1.22-2.87, and OR= 1.83; 95% CI = 1.21-2.76, respectively. Conclusion: The results of this study confirmed previous results showing significant associations of COPD risk with some components of MDS. Extensive studies are needed to explore MDS components better and suggest more effective interventions to maintain healthy eating habits and reduce COPD risk.

Background: Congenital hearing loss has been linked with life-long deficits in speech and language abilities and children with vestibular deficits show delayed development of gross motor milestones. Aim and scope of the research: To analyze if the universal neonatal hearing screening (UNHS) and vestibular screening program in Flanders meet the current guidelines and benchmarks of the position statements from the Joint Committee on Infant Hearing and how big the impact of screening devices and strategy is. Methods: The UNHS is organized since 1997 by a Flemish public child care organization and performed by trained nurses. It is based on a two-step screening with Automated Auditory Brainstem Responses and in case of absent responses (named ‘refer’), audiological and medical diagnostic are done in one of 21 certified centers. Vestibular screening started in 2018 around the age of 6 months with cervical Vestibular Evoked Myogenic Potentials (cVEMP) for all children with confirmed permanent hearing loss. Results: The coverage of the UNHS from 1998 till 2020 was 96,3 % (range 91,1 – 98%). There was a bilateral refer for 0,27 % of the infants and unilateral refer for 0,37 %. A sensorineural or mixed hearing loss > 40 dB was diagnosed in 32 % of the referred infants, a conductive hearing loss which often resolved over time in 39 %, a normal hearing in 25% and 4,7 % were lost in follow-up for the diagnostic evaluation. There was an effect of the screening device on the detection of conductive hearing losses and false-positive cases. The incidence was higher with the MAICO MB Classic® device compared to the ALGO® devices. The incidences of sensorineural or mixed hearing loss were independent of the screening device and remained relatively stable over the years. A vestibular deficit was found in 9,5 % of all children with sensorineural hearing loss. The incidence was significantly higher in infants with severe or profound hearing loss (p=0,003) Conclusion: The Flemish UNHS has a high coverage, low referral rate and low loss of follow-up rate. Strict monitoring and follow-up by a central organization are essential for optimal results. Long-term follow-up remains a challenge.
