Dysregulation of the activity of the mechanistic target of rapamycin complex 1 (mTORC1) is commonly linked to aging, cancer, and genetic disorders such as tuberous sclerosis (TS), a rare neurodevelopmental multisystemic disease characterized by benign tumors, seizures, and intellectual disability. Although patches of white hair on the scalp (poliosis) are considered as early signs of TS, the underlying molecular mechanisms and potential involvement of mTORC1 in hair depigmentation remain unclear. Here, we have used healthy, organ‐cultured human scalp hair follicles (HFs) to interrogate the role of mTORC1 in a prototypic human (mini‐)organ. Gray/white HFs exhibit high mTORC1 activity, while mTORC1 inhibition by rapamycin stimulated HF growth and pigmentation, even in gray/white HFs that still contained some surviving melanocytes. Mechanistically, this occurred via increased intrafollicular production of the melanotropic hormone, α‐MSH. In contrast, knockdown of intrafollicular TSC2, a negative regulator of mTORC1, significantly reduced HF pigmentation. Our findings introduce mTORC1 activity as an important negative regulator of human HF growth and pigmentation and suggest that pharmacological mTORC1 inhibition could become a novel strategy in the management of hair loss and depigmentation disorders.

Authors: Álvarez-Gómez Yesmmy , Ricardo Delgado Daniel
Published: May 2023

[Introduction]: Contaminants of emerging concern (CECs) are now a subject of interest for various areas of scientific research, mostly international studies are identified, however, there is still insufficient information on the true effects of these compounds on the environment and on the health of populations that are in contact with these types of contaminants, requiring in turn the search and execution of effective treatments to minimize their bioaccumulation in the environment, especially those substances of pharmaceutical origin, which are already being recognized for their high degree of toxicity. [Objective]: In the present investigation, the degradation of the emerging contaminant methylparaben was studied. [Methodology]: For this study, the distilled water was contaminated, after which the analysis of the effectiveness of ozone, ultraviolet radiation, and the combined treatment of UV radiation and ozonation in the degradation of the substance of pharmaceutical origin was carried out. [Results]: In the study it was found that the combined treatment of UV radiation and ozonation was more effective in the degradation of methylparaben, compared to the techniques of UV and Ozone radiation used separately. [Conclusions]: The results obtained in this research generate information regarding a new alternative that allows the degradation of pharmaceutical contaminants, such as methylparaben, to minimize the environmental impact of this type of substance.

Authors: Gupta Aman , Dutt Bhupender , Sharma Sonika
Published: May 2023

Effects of thermal modification were determined relative to chemical parameters of Pinus roxburghii. Thermal modification of wood was carried out at 80, 120, 160, and 200 °C for 2, 4, and 6 h. The chemical properties were different for different temperatures and different heating time. All parameters were similar except for cold water soluble extractives. Among the chemical properties studied, the maximum mean value of cold water extractives (8.20%), hot water soluble extractives (12.7%), holocellulose content (71.8%), and ash content (1.46%) were recorded at 120 °C, whereas the maximum mean values of alcohol benzene soluble extractives (13.9%) and lignin content (33.7%) were observed at 200 °C. The minimum mean value of cold water soluble extractives (5.82%), hot water soluble extractives (9.27%), holocellulose content (65.8%), and ash content (1.03%) were found to be at 200 °C, while the highest value of alcohol benzene soluble extractives 12.2% (control) and lignin content (28.0%) were found to be at 80 °C.
The Welfare State Scattergram
Authors: Askola Joni , Davison Benjamin
Published: May 2023

Welfare states have traditionally been studied through quantitative tools such as indices and qualitative ones such as typologies. However, there seems to be a lack of analytical tools that simultaneously show welfare state outcomes and development potential. In this paper, we developed the Welfare State Scattergram. This result of two indices gives the welfare state’s outcomes and fiscal capacity, the latter serving as a proxy for improvement potential. The indicator used for the X-axis is a modified debt-sustainability formula to indicate fiscal capacity and, thus, the development potential of the welfare state. The indicator used for the Y-axis gives the welfare state outcomes and consists of a weighted welfare state outcomes indicator.
„You Won’t Break the Ice and Won’t Talk about It“: Mental Health Professionals’ Difficulties in Providing Assistance to Individuals who Later Suicide

Published: May 2023

Accessible and effective mental health services for people at risk of suicide are one of the cornerstones of suicide prevention. However, some people suicide while receiving such help, and it is important to understand the reasons for this. In the absence of a direct way to reveal the experiences of people who have received services and subsequently suicided, the professionals providing mental health services are an important source of information on this process. The main aim of this study was to describe the main difficulties experienced by professionals supporting people who later suicided. The sample included 15 mental health professionals (7 psychiatrists, 6 medical psychologists, and 2 social workers) who experienced patient suicide. The data were collected using semi-structured interviews, which were then analysed using thematic analysis. The following themes were identified in the stories of the participants: lack of collaboration from the patient, specific topics that were challenging to work with, treatment limitations, difficulties in assessing suicide risk, reactions experienced when working with the suicidal patient, and the role of the patient’s relatives. Therefore, the results of this study speak about the challenge of being with a patient in a suicidal crisis, who is not inclined to accept help, while bearing the limitations of the system and oneself as a specialist. This causes intense experiences of helplessness and anger.
Technical specialization in Nuclear Medicine: an analysis of courses in Brazil and a proposal for a basic curriculum
Authors: Clavery Maicon B. , Razuck Fernando Barcellos
Published: May 2023

Nuclear Medicine (NM) is a medical specialty that, through non-invasive methods, uses radioactive materials for diagnostic and therapeutic purposes. According to Standard NN 3.05 of the Brazilian National Nuclear Energy Commission (CNEN), a Nuclear Medicine System (NMS) must be composed of, at least, a Holder, a Nuclear Physician, a Radiation Protection Supervisor and higher and mid-level professionals, duly qualified for the performance of their duties, which may be exercised, in this case, by a radiology technician. Thus, in 2009, the National Council of Radiology Technicians (CONTER) granted a period of 5 (five) years for radiology technicians who work in the NM and Radiotherapy specialties to specialize in their areas of expertise, a period that was extended for another 5 (five) years. In this sense, this paper aims to carry out a survey of the Technical Specialization courses in NM offered in Brazil, considering that almost 10 years have passed since the CONTER Resolution No. 17, of 2014, verifying aspects such as structure and workload, based on the requirements of the Ministry of Education (MEC), in order to suggest a core curriculum for courses in NM. It was found that, with the legal requirement of this training, these courses began to be offered, but in a reduced number and only in some regions of Brazil, despite the existence of courses in the distance modality. It is understood, therefore, that an expansion of courses in the area is necessary, in view of the relevance of the service for NM.

Analysis of Horse Bones from a Cellar of the 11th⸺12th Centuries near the Western Palace in Kyiv
Authors:   PhD, Research Fellow, the Institute of Archaeology, the National Academy of Sciences of Ukraine, the Bioarchaeology Department, Kublii Mykhailo
Published: May 2023

During archaeological excavations in the Upper Town in Kyiv in 2008, a cellar was discovered next to the Western Palace. Among other materials, there were animal bones, the absolute majority of which were horses’ bones. Based on the bones, it was calculated that the minimum number of individual horses was four. These bones belonged to kitchen remains, as they were fragmented and showed a large number of cutting marks on almost all anatomical parts of the horses. However, they were larger than those that are usually thrown away after cooking. Perhaps, in this case, we are dealing with horse carcasses that were stored as supplies after initial butchering, but never used. The presence of bones from non-meat parts of the body, such as the phalanges, indicates that the animals were slaughtered in the same place. According to the nature of the cut marks, they were probably made with an ax and a knife. Two of the horses were likely males. The sex of the other two could not be determined. Two individuals were five years old, one was 3—3.5 years old, and one was 15—18 months old. Breed characteristics were established only for one individual. The female belonged to medium-legged horses. In addition, the horse performed heavy physical work during life, which is indicated well-developed muscle attachments on the bones. It should be noted that by the 11th and 12th centuries, the practice of eating horse meat had stopped. There are several reasons for this. One of them is changing the role of the horse. At this time, the horse began to be actively used as a draft animal, particularly when cultivating the land, and as a riding animal. Another reason is the spread of Christianity, which prohibited eating horse meat, because it was associated with pre-Christian cults. This is evidenced by several references in the Chronicle. However, under unforeseen circumstances, such as famine during the siege of the city, the practice of eating horse meat could have been returned. It is likely that the horses, the bones of which were found in the cellar, were slaughtered and divided into fragments precisely under unfavourable circumstances for the residents of Kyiv.

Book collectors and patrons of the Zólyomradvány Bibliotheca
Authors: Czeglédi László
Published: May 2023

Over many decades, the library of Radvány castle has developed into a valuable and organized collection. The founders and owners of the library were members of the Radvánszky family from Radvány right until the time when it finally became state property. The collection has been described on several occasions, and the state of the library has been explored several times in the literature; however, to date, its holdings have not been described and published in detail. However, the specialist would be in an easy position, since catalogs have survived and, in addition, a significant part of the collection still exists, so there is a good chance that the library's stock can be reconstructed. The real and the supposed processes of building the collection may be traced back quite clearly over a period of more than a century and a half.
The Character of ‘Passive Hero’ in the Narrative Structures of Korea’s Premodern Literature
Authors: Riotto Maurizio
Published: May 2023

This article examines the figure of the passive hero first in the Korean literature of origins, and then in classical Korean literature of the Koryŏ and Chosŏn periods. After a general introductory section, in which the worldwide literary archetype of the hero and its evolution over time are examined, the author, specifically examining Korean literature, analyzes in part one the passive heroes of four short historical/mythological stories variously set in an era between the second and eighth centuries, and then part two of the article analyzes three passive hero figures as protagonists of one 14th-century tale and two 18th-century classic novels. The author thus shows how the narrative of the passive hero has undergone a significant transformation in Korea, passing from a mythical/spiritual state (which often does not even admit the figure of an antagonist) to a decidedly secular, materialist and politicized condition where the protagonists find themselves facing cultural superstructures which, in addition to generating antagonists, push passive heroes towards true forms of defensive fundamentalism.

Published: May 2023

Relevance. Structural changes in the Russian market create new trends, including energy supply in remote areas. The government is planning to redirect natural gas to domestic buyers. However, according to the estimates of biogas potential, it can fully meet the energy needs of households with no access to centralized gas supply. Research objective is to choose the optimal scenario of gasification in remote areas by evaluating the economic feasibility of several alternatives, including biogas technologies and the centralized gas supply system. Data and methods. The study focuses on the case of Sverdlovsk region and considers three scenarios of gasification in its remote areas. The method includes the calculation of the full discounted value of energy facilities, the comparison of their productive capacity, the analysis of the key external factors. Results. In terms of cost, the most economically feasible is the scenario of biogas plants using by individual households. However, accounting productivity, the scenarios based on the use of centralized gas supply or collective biogas plants. The economic feasibility of these two scenarios depends on the number of buildings serviced. Conclusions. The optimal scenario is the centralized gas supply. Despite its high costs, it can ensure the uninterrupted supply of the necessary energy amount to private households and does not depend on factors such as the availability of manure and organic waste and weather conditions. One more advantage is that Russia currently has a more elaborate and adequate legal framework regulating its use than for the other two options.

Relevance. Recent practice has convincingly tested the fact that the transition to a circular economy is an important goal for society and individual companies, especially in resource-intensive manufacturing industries. Research objective. The purpose of the study is to develop a theoretical and methodological basis for the creation of innovative solvates in regional industry, based on the concept of circular economy. Data and methods. The research methodology is represented by the convergence of system-synergetic, resource-efficient and cluster approaches, which makes it possible to identify regions where integrating industrial enterprises and related fields of activity form conditions and produce values in the concept of the circular economy. Results. The theoretical and methodological basis for the creation of new structures for the innovative development of regional industry on the platform of circularity, principles of inclusiveness, resilience and environmental friendliness has been formed; a new concept - innovative solvates has been introduced into scientific circulation. Based on the cluster analysis, the zones of localization of innovative solvates in the regions of Russia were identified. This made it possible to single out a cluster group with a high scientific and innovative potential, as well as a cluster of regions with the potential to localize innovative solvates, which included regions of industrial and resource specialization. Conclusions. The article presents the directions of solving the problem of achieving the conditions imposed by the circular economy in the innovative solvates of the industrial sector of the region. The study is motivated by several considerations. The first is the formation of an integral conceptual and terminological apparatus, theoretical and methodological basis of research. The second is the establishment of partnerships necessary for the implementation of circularity conditions in an innovative solvate, and the analysis of ways in which a solvate can switch to a circular economy.

ABSTRACT Introduction: with the improvement and wide acceptance of laparoscopy in colorectal operations, there was a need for specific training of surgeons in training. There are few studies evaluating the postoperative results of laparoscopic colectomies performed by resident physicians and their impact on patient safety. Purpose: to analyze the surgical and oncological results of laparoscopic colectomies performed by coloproctology residents and compare them with data in the literature. Methods: this is a retrospective analysis of patients undergoing laparoscopic colorectal surgery performed by resident physicians at the Hospital das Clínicas de Ribeirão Preto, between 2014 and 2018. The clinical characteristics of the patients were studied, as well as the main surgical and oncological aspects in a period of one year. Results: we analyzed 191 operations, whose main surgical indication was adenocarcinoma, most of them stage III. The mean duration of surgeries was 210±58 minutes. There was a need for a stoma in 21.5% of the patients, mainly loop colostomy. The conversion rate was 23%, with 79.5% due to technical difficulties, and the main predictors of conversion were obesity and intraoperative accidents. The median length of stay was 6 days. Preoperative anemia was associated with a higher rate of complications (11.5%) and reoperations (12%). Surgical resection margins were compromised in 8.6% of cases. The one-year recurrence rate was 3.2% and the mortality rate was 6.3%. Conclusions: videolaparoscopic colorectal surgery performed by residents showed efficacy and safety similar to data found in the literature.

Published: May 2023

RESUMO Este artigo sugere que as cláusulas antidumping na Organização Mundial do Comércio podem ter um impacto positivo no crescimento dos países do Terceiro Mundo. O aumento dos custos de mão de obra causado pressionaria por mudanças técnicas mais rápidas, acelerando o crescimento. Os possíveis desequilíbrios de curto prazo nas contas correntes seriam temporários e desapareceriam no longo prazo. Também se argumenta que as alianças políticas para introduzir tais cláusulas em uma organização internacional podem ser uma mudança importante no cenário político mundial, trazendo esperança de futuras relações internacionais prevalecentes que possam ser mais positivas para o crescimento do Terceiro Mundo.

Abstract Background Studies show that among the drugs most commonly used in judicial litigation in Brazil, are those used to treat diabetes mellitus, especially insulin analogues. Objective Evaluate the use of the Unified Health System (SUS) by patients with type 1 diabetes mellitus (T1DM), who receive insulin analogues through judicial action, before and after this process. Method In a retrospective longitudinal observational study, secondary data was used from these patients in Minas Gerais, Brazil, in 2018. Socio-demographic information was collected and related to the follow-up of these patients in the SUS. The McNemar χ2 test was used to compare the proportions of the variables. Results Of the 89 patients analyzed, women (53.9%) were predominant. Most patients were aged between 20 and 39 years (52.8%), and more than half, 55.1%, use only a private health system. After the judicial action, there was a significant increase (p <0.05) in the number of patients who had consultations in primary health care (from 19.1% to 30.3%) and emergency medical appointments (from 1.1% to 9.0%). Conclusion It is observed that the majority of patients with T1DM via judicial action in the SUS are not monitored by this health system through examinations, consultations, and hospitalizations.

By telling Nuveo’s story, this teaching case allows the identification of principles and recommendations for ethical development and use of AI systems, enabling discussions about ethical challenges related to digital transformation and its impacts on individuals, companies, and society. It is intended for use at undergraduate and graduate courses in business administration, public administration, and information technology and can be applied in disciplines that address digital ethics, ESG (environmental, social, and governance), and artificial intelligence.
Effect of drying conditions on physiological quality of cowpea seeds of the cultivar brs-tumucumaque
Authors: Assis Miquéias de O. , Araujo Eduardo F. , de Freitas Francisco C. L. , da Silva Laercio J. , Araujo Roberto F.
Published: May 2023

ABSTRACT Seed drying has many advantages, but it can cause irreversible damages, compromising the physiological quality of seeds, especially when they present high water contents. The objective of this work was to evaluate the effect of drying conditions (inside and outside the pod) on the physiological quality of cowpea seeds of the cultivar BRS-Tumucumaque before and after storage. A completely randomized experimental design with four replications was used, in a split-plot arrangement. The plots consisted of combinations of harvest seasons (1, 2, 3, 4, and 5) and artificial seed drying conditions (inside and outside the pod); and the subplots consisted of storage times (0 and 6 months). The seed water contents were determined and the seeds were evaluated for germination, first germination count, emergence, emergence index, accelerated aging, and electrical conductivity. Higher physiological quality was found for dried seeds inside the pods, which was more evident in seasons 1 and 2, in both storage times. In the other seasons, the drying conditions had no effect on seed germination and vigor at the beginning of storage. The dried seeds inside the pods showed greater vigor after six months of storage. Drying seeds inside the pods favors the maintenance of physiological quality and allows artificial drying of cowpea seeds of the cultivar BRS-Tumucumaque with water content of 47%. Artificial drying of seeds with water contents higher than 32.5% is not recommended for the condition outside the pod. The seed physiological potential decreases after six months of storage, regardless of the drying condition.

ABSTRACT Tangerines and their hybrids are affected by economically essential diseases. The Alternaria brown spot (Alternaria alternata f. sp. citri) deserves to be highlighted, as it is present in all tangerine production areas. This study aimed to determine the effect of essential oils on A. alternata f. sp. citri. The experiments were carried out in the Laboratories of Phytopathology and Biology and Technology of Post-Harvest of the Federal University of Paraíba, Areia, PB. Three pathogen isolates were used, and ten essential oils from grape, sunflower, eucalyptus, ginger, copaiba, mint, fennel, citronella, clove, and linseed at a concentration of 1%, diluted in potato dextrose agar for in vitro tests. The oils were diluted in distilled water for the fruit test, and the fruits were immersed in the treatments for 5 min. In addition, the fungicide Thiabendazole (400 mL/100L) and sterile distilled water were used as the control treatments. The fruits were inoculated with a conidia suspension of the pathogen (105 conidia/mL). Mycelial Growth Rate Index, colony diameter, spore production and dimensions, fruit disease severity, and enzymatic activity were evaluated. A completely randomized design was used, with 12 treatments and four replications in vivo. The results indicate that the essential oils of mint, eucalyptus, fennel, and citronella were efficient in the in vitro control of the pathogen, ultimately inhibiting the growth of fungal colonies. Eucalyptus oil efficiently managed A. alternata f. sp. citri on ‘Dancy’ tangerine fruits. Essential oils did not influence the enzymatic activity of the fruits.

Published: May 2023

ABSTRACT The low mean yield of sweet potato crops in Brazil is related to several inadequate crop management practices. Considering the increasing production of this vegetable, the objective of this work was to evaluate the yield response of sweet potato crops subjected to different NPK fertilizer rates (NPK) combined with different growth regulator concentrations. The experiment was carried out in a randomized block design, with a 5×5 factorial arrangement consisted of 5 NPK fertilizer rates (0, 696, 1044, 1392, and 1740 kg ha-1) combined with 5 growth regulator concentrations (0, 20, 25, 30, and 35 mL L-1). Numbers of total and commercial roots per plant were affected by the factors tested, presenting a linear increase as the rates and concentrations were increased. The highest estimated sweet potato yield was 43 Mg ha -1, which was obtained using a NPK rate of 1522.64 kg ha-1 and a growth regulator concentration of 34.69 mL L-1. The higher NPK rates improved water use efficiency up to a maximum value of 8.1 kg m-3 with application of the NPK rate of 1740 kg ha-1. After determining a fixed yield level, the production factors tested act as imperfect substitutes in some intervals of variation of the inputs.

ABSTRACT Simultaneous selection for plant architecture and yield traits will be more efficient if a minimum number of experiments is established, but no such definition has been made for common bean. The objectives of this study were to select superior common bean lines for several plant architecture and yield traits and identify the minimum number of experiments that provide greater efficiency in simultaneous selection for agronomic traits. Twelve plant architecture and five yield traits of common bean lines were evaluated in four experiments. Analysis of variance and selection index (multiplicative) were carried out using data from individual experiments I (2016 rainy), II (2017 dry), III (2017 rainy), and IV (2018 dry-season crops), or data from two (I and II), three (I, II, and III), and four (I, II, III, and IV) experiments. Most agronomic traits showed a significant genotype × experiment interaction effect. The use of data from individual experiments resulted in variable heritability and genetic gain estimates and in the selection of different common bean genotypes for each growing environment. However, data from three or four experiments allowed 100% of coincidence in the selection of four superior common bean genotypes: LP 09-33, BRS Valente, Pérola, and Carioca. Data from at least three experiments should be used to select superior common bean lines for plant architecture and yield traits to increase the efficiency of simultaneous selection.

ABSTRACT The use of high doses of vinasse in sugarcane crop can cause modifications in the chemical characteristics of the soil. The aim of this study was to evaluate the effect of the application of high doses of vinasse on the chemical characteristics of an Ultisol cultivated with sugarcane for 210 days. The treatments used were doses equivalent to 0 (D0), 150 (D150), 300 (D300), 600 (D600) and 1200 (D1200) m3 ha-1 of vinasse plus a control treatment with mineral fertilization. The experimental design was completely randomized with six treatments and six repetitions. Exchangeable potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na) contents, organic matter, cation exchange capacity, sodium adsorption ratio, exchangeable sodium percentage, electrical conductivity and pH were analyzed at 90, 120, 150 and 210 days after planting (DAP), in addition to microbial basal respiration at 210 days at depths of 0-0.20 and 0.20-0.40 m. Soil pH increased with the use of vinasse within the proper range for sugarcane, varying from 6.2 to 6.4. The highest K and Na contents were found at D600 and D1200; the highest K and Na availability occurred at 120 DAP and 150 DAP, respectively, indicating competition between these nutrients for exchange sites. Organic matter content was proportionally high according to the vinasse dose applied. D600 and D1200 doses increased Na content in the soil, with greater magnitude at the 0-0.20 m depth.

ABSTRACT It is believed that nitrogen fertilization will attenuate the salt stress on pearl millet plants. Thus, the objective was to evaluate the agronomic performance of the millet crop under different saline water irrigation strategies and nitrogen fertilization. The experimental design adopted was completely randomized (CRD), in a 4 x 2 factorial scheme, with 4 replicates, with the first factor being four irrigation strategies: S1 = low-salinity water (W1) = 0.3 dS m-1 throughout the cycle; S2 = saline water (W2) = 4.0 dS m-1 from 30 days after sowing - DAS; S3 = W2 from 45 DAS; and S4 = W2 from 65 DAS; and the second factor being two nitrogen doses (60 and 120 kg ha-1 of N). At the end of the experiment, the following variables were evaluated: photosynthesis, transpiration, stomatal conductance, instantaneous water use efficiency, internal CO2 concentration, leaf temperature, plant height, stem diameter, root length, panicle length, leaf dry mass, stem dry mass and root dry mass. Fertilization with 60 and 120 kg ha-1 promotes greater photosynthesis, transpiration, stomatal conductance and internal CO2 concentration in millet plants under the strategies S1, S2 and S3. The strategies S1 and S4 were more efficient to increase the efficient use of water and reduce leaf temperature.

ABSTRACT Purpose To identify the reasons that lead the individual to follow or not the recommendation to use the hearing aid and its use over the years. Research strategy Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) recommendations were followed. The databases searched were: Pubmed, Pubmed Central, Scopus, Embase, Web of science and Cochrane, using the following descriptors: “Hearing Aids”, “Patient Compliance” and the Boolean indicator AND. Selection criteria primary original articles with prospective, retrospective, observational or experimental designs; that raise, report, verify or analyze the reasons for adherence or not to the use of hearing aids, regardless of being an experienced user or not; carried out with the young, adult and elderly population; with individuals with any degree, type and configuration of hearing loss; with unilateral or bilateral adaptations and in Portuguese, English and Spanish. Results 27 studies were included in the analysis. There were two distinct situations in the auditory rehabilitation process: acceptance of the indication of the use of HA and the continuity of the effective use. Thus, the aspects that positively, negatively or do not interfere in these two phases were compiled and presented. Conclusion the most relevant factors in the non-adherence to HA were: perception of low cost-benefit, lack of understanding of the real need and difficulty in accepting its use; while the ones that most impacted the continuity of use were: HA sound quality, handling difficulties and perception of little benefit.

RESUMO Objetivo identificar os motivos que levam o indivíduo a seguir ou não a recomendação da necessidade do uso do aparelho de amplificação sonora individual (AASI) e a utilização desse dispositivo ao longo dos anos. Estratégia de pesquisa orientações do Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) foram seguidas. As bases de dados pesquisadas foram: Pubmed, Pubmed Central, Scopus, Embase, Web of Science e Cochrane, utilizando os seguintes descritores: “Hearing Aids”, “Patient Compliance” e o indicador booleano AND. Critérios de seleção artigos originais primários com desenhos prospectivos, retrospectivos, observacionais ou experimentais; que levantassem, relatassem, verificassem ou analisassem os motivos de adesão ou não ao uso de AASI, independentemente de ser usuário experiente ou não; realizados com a população jovem, adulta e idosa; com indivíduos com qualquer grau, tipo e configuração de perda auditiva; com adaptações unilaterais ou bilaterais e em português, inglês e espanhol. Resultados incluídos 27 estudos na análise. Verificaram-se duas situações distintas no processo de reabilitação auditiva: aceitação à indicação do uso do AASI e a continuidade do uso do dispositivo de maneira efetiva. Os aspectos que auxiliaram positivamente, negativamente ou não interferiram nessas duas fases foram compilados e apresentados. Conclusão os fatores de maior relevância para a não aquisição do AASI são: percepção de baixo custo-benefício, falta de entendimento da real necessidade e dificuldade de aceitação do uso, enquanto que os que mais impactam na continuidade do uso são: qualidade sonora do AASI, dificuldades de manuseio e percepção de pouco benefício.
