Adsorption of extracellular lipase in a packed-bed reactor: an alternative immobilization approach.

In light of the growing demand for novel biocatalysts and enzyme production methods, this study aimed to evaluate the potential of Aspergillus tubingensis for producing lipase under submerged culture investigating the influence of culture time and inducer treatment. Moreover, this study also investigated conditions for the immobilization of A. tubingensis lipase by physical adsorption on styrene-divinylbenzene beads (Diaion HP-20), for these conditions to be applied to an alternative immobilization system with a packed-bed reactor. Furthermore, A. tubingensis lipase and its immobilized derivative were characterized in terms of their optimal ranges of pH and temperature. A. tubingensis was shown to be a good producer of lipase, obviating the need for inducer addition. The enzyme extract had a hydrolytic activity of 23 U mL-1 and achieved better performance in the pH range of 7.5 to 9.0 and in the temperature range of 20 to 50 °C. The proposed immobilization system was effective, yielding an immobilized derivative with enhanced hydrolytic activity (35 U g-1), optimum activity over a broader pH range (5.6 to 8.4), and increased tolerance to high temperatures (40 to 60 ℃). This research represents a first step toward lipase production from A. tubingensis under a submerged culture and the development of an alternative immobilization system with a packed-bed reactor. The proposed system holds promise for saving time and resources in future industrial applications.

Self-inflicted burns in Brazil: systematic review and meta-analysis.

INTRODUCTION: burns represent a pivotal component of trauma in Brazil, accounting for 2 million incidents and 2,500 deaths annually. Self-intentional burns are associated with a worse prognosis, larger burned surface area, higher infection rates, and death. The lack of studies on the issue of self-immolation raises epidemiological questions regarding Brazilian victims. This study aimed to investigate the profile of burn events associated with self-injurious behavior among Brazilian victims. METHODS: this systematic review was performed according to PRISMA 2020 guidelines and evaluated the correlation between self-injurious behavior as a cause of burns in Brazilian victims and its epidemiological implications in the last 20 years (2003-2023). The MeSH terms "Burns", "Self-Injurious Behavior", "Epidemiology" and "Brazil" were queried in the PubMed/MEDLINE, SciELO, and Cochrane Library databases, and, after selection by inclusion/exclusion criteria, the most relevant studies were critically analyzed. RESULTS: From 1,077 pre-selected studies, 92 were potentially eligible, resulting in 7 manuscripts incorporated in this review. From 3,510 burned victims assembled in the pool of selected studies, 311 cases displayed self-injurious behavior. Burned patients who attempted to burn their lives have a higher risk of death (p<0.05; RR=5.1 [3.2-8.1]) and larger burned surface area (p<0.05; MD=19.2 [10-28.2]), compared to accidental cases. Moreover, the female gender was at a higher risk of attempting self-immolation (p<0.05; RR=4.01 [2.9-5.5]). CONCLUSION: our results show that self-inflicted burn cases were associated with a larger burned surface area and a higher risk of death, and the female gender was identified as a relevant risk factor in Brazil.

The reorganization of predator-prey networks over 20 million years explains extinction patterns of mammalian carnivores.

Linking the species interactions occurring at the scale of local communities to their potential impact at evolutionary timescales is challenging. Here, we used the high-resolution fossil record of mammals from the Iberian Peninsula to reconstruct a timeseries of trophic networks spanning more than 20 million years and asked whether predator-prey interactions affected regional extinction patterns. We found that, despite small changes in species richness, trophic networks showed long-term trends, gradually losing interactions and becoming sparser towards the present. This restructuring of the ecological networks was driven by the loss of medium-sized herbivores, which reduced prey availability for predators. The decrease in prey availability was associated with predator longevity, such that predators with less available prey had greater extinction risk. These results not only reveal long-term trends in network structure but suggest that prey species richness in ecological communities may shape large scale patterns of extinction and persistence among predators.

Accuracy of infrared thermography evaluation in burn wound healing: a systematic review and meta-analysis.

OBJECTIVE: Accurate assessment of burn depth and burn wound healing potential is essential to determine early treatments. Infrared thermography (IRT) is a non-invasive and objective tool to do this. This systematic review evaluated the accuracy of IRT to determine burn wound healing potential. METHOD: This systematic review and meta-analysis used MEDLINE, EMBASE, CINAHL, PEDro, DiTA and CENTRAL databases. IRT data were extracted from primary studies and categorised into four cells (i.e., true positives, false positives, true negatives and false negatives). Subgroup analysis was performed according to methods used to capture thermal images. RESULTS: The search strategy identified 2727 publications; however, 15 articles were selected for review and 11 for meta-analysis. In our meta-analysis, the accuracy of IRT was 84.8% (63% sensitivity and 81.9% specificity). CONCLUSION: IRT is a moderately accurate tool to identify burn depth and healing potential. Thus, IRT should be used carefully for evaluating burn wounds.

Vocal Tract Discomfort Scale-Brazil (VTDS-BR): Validation Based on Internal Consistency, Reliability, and Accuracy.

OBJECTIVE: To validate the Vocal Tract Discomfort Scale for the Brazilian Portuguese (VTDS-BR), based on internal consistency, reliability, and accuracy. METHODS: The participants were 431 adults of both sexes, divided in two groups: dysphonia (DG) and vocally healthy (VHG). We built a digital database with personal, professional information and the item-by-item VTDS-BR responses of the participants. We applied Cronbach's alpha, exploratory factor analysis; confirmatory factor analysis; Item Response Theory (IRT) using the Samejima model; and ROC (Receiver Operating Characteristic) curve analysis to obtain the VTDS-BR cut-off point. RESULTS: The VTDS-BR has an eight-item structure and two factors: vocal hyperfunction without phonotraumatic injury and with phonotraumatic injury. Each item is evaluated based on two facets related to frequency and intensity, with a Likert scale response key. There are four possible answers: never, sometimes, often, and always for frequency and none, mild, moderate, and intense for intensity. We applied an IRT model, which allowed the identification of which items are more related to dysphonia, based on higher values in the parameters discrimination (a) and difficulty (b), which contributed to the calculation of each participant's aptitude for the development of voice problems, by means of a score. The cut-off value was determined using the ROC curve, in which values greater than - 1.432 indicate a higher probability of voice alterations. CONCLUSION: VTDS-BR went through the stages of validation of internal consistency, reliability, and accuracy. It presents an 8-item, two-factor, and two-facet structure to assess frequency and intensity of vocal tract discomfort symptoms. VTDS-BR is suitable for clinical use or in screening activities, as it is quick to apply and its interpretation is indicative of people with and without phonotraumatic injury.

Immunogenicity and safety of inactivated SARS-CoV-2 vaccine (CoronaVac) using two-dose primary protocol in children and adolescents (Immunita-002, Brazil): A phase IV six-month follow up.

Introduction: Vaccines are essential for the prevention and control of several diseases, indeed, monitoring the immune response generated by vaccines is crucial. The immune response generated by vaccination against SARS-CoV-2 in children and adolescents is not well defined regarding to the intensity and medium to long-term duration of a protective immune response, which may point out the need of booster doses and might support the decisions in public health. Objective: The study aims to evaluate the immunogenicity and safety of inactivated SARS-CoV-2 vaccine (CoronaVac) in a two-dose primary protocol in children and adolescent aging from 3 to 17 years old in Brazil. Methods: Participants were invited to participate in the research at two public healthcare centers located in Serrana (São Paulo) and Belo Horizonte (Minas Gerais), Brazil. Participants underwent medical interviews to gather their medical history, including COVID-19 history and medical records. Physical exams were conducted, including weight, blood pressure, temperature, and pulse rate measurements. Blood samples were obtained from the participants before vaccination, 1 month after the first dose, and 1, 3, and 6 months after the second dose and were followed by a virtual platform for monitoring post-vaccination reactions and symptoms of COVID-19. SARS-CoV-2 genome from Swab samples of COVID-19 positive individuals were sequenced by NGS. Total antibodies were measured by ELISA and neutralizing antibodies to B.1 lineage and Omicron variant (BA.1) quantified by PRNT and VNT. The cellular immune response was evaluated by flow cytometry by the quantification of systemic soluble immune mediators. Results: The follow-up of 640 participants showed that the CoronaVac vaccine (Sinovac/Butantan Institute) was able to significantly induce the production of total IgG antibodies to SARS-CoV-2 and the production of neutralizing antibodies to B.1 lineage and Omicron variant. In addition, a robust cellular immune response was observed with wide release of pro-inflammatory and regulatory mediators in the early post-immunization moments. Adverse events recorded so far have been mild and transient except for seven serious adverse events reported on VigiMed. Conclusions: The results indicate a robust and sustained immune response induced by the CoronaVac vaccine in children and adolescents up to six months, providing evidences to support the safety and immunogenicity of this effective immunizer.

Renal vein thrombosis in the course of non-operative treatment of kidney trauma: A rare case report.

INTRODUCTION: Venous thromboembolism is widely recognized as a life-threatening complication in trauma, yet renal vein thrombosis (RVT) following trauma is particularly rare. PRESENTATION OF CASE: We report a case of a 67-year-old man who was brought to the emergency department after falling down a 14-step staircase at home which presented right kidney trauma (parenchyma laceration with a perirenal hematoma) on computed tomography, and hematuria. Considering the patient's hemodynamic stability, a non-operative treatment was initiated, and the patient was referred to the intensive care unit for close observation. On post-trauma day 3, a repeated CT revealed right renal vein thrombosis. After evaluation, it was decided to maintain prophylactic anticoagulation doses of enoxaparin (40 mg/day) due to the elevated risk of bleeding in high-grade renal trauma and planned an inferior vena cava (IVC) filter placement. In the following days, the hematuria resolved spontaneously and an IVC filter was placed. The patient progressed with no complaints, spontaneous diuresis, improvement in laboratory parameters, and cardiovascular stability, which led to his discharge on day 12 with rivaroxaban 10 mg/day. The patient was successfully treated with a non-operative approach, and the RVT disappeared after 35 days. DISCUSSION: Post-traumatic renal vein thrombosis is a rare occurrence, and due to the infrequent nature of these events, specific management guidelines are not fully established, particularly when thrombosis is confirmed in an acutely injured patient. CONCLUSION: Conservative therapy seems to play a meaningful role in trauma-related renal vein thrombosis treatment.

Olfactory and taste disorders in COVID-19: a cross-sectional study in primary health care.

OBJECTIVE: The objective of this study was to describe the occurrence of self-reported olfactory and taste disorders in non-hospitalized Brazilian adults who presented severe acute respiratory syndrome-related coronavirus 2 infection symptoms and attended primary health care. METHODS: This cross-sectional study was based on a routine standardized diagnostic screening questionnaire applied in a Brazilian primary care facility. The olfactory and taste disorder occurrence was compared between severe acute respiratory syndrome-related coronavirus 2-positive and severe acute respiratory syndrome-related coronavirus 2-negative cases and described by age and sex. RESULTS: Severe acute respiratory syndrome-related coronavirus 2-positive patients had a higher proportion of self-reported olfactory and taste disorders, as compared with severe acute respiratory syndrome-negative (50.7%, vs. 20.6%, p<0.0001). Of all individuals with self-reported olfactory and taste disorder cases, 69% presented both olfactory and taste impairments, 13% olfactory only, and 17% taste only. In severe acute respiratory syndrome-related coronavirus 2-positive cases, the frequency of olfactory and taste disorders was significantly higher among females as compared with males (71% vs. 34%). Additionally, people with olfactory and taste disorders were significantly younger in the severe acute respiratory syndrome-related coronavirus 2-positive group. CONCLUSION: Self-reported olfactory and taste disorders are highly common among non-hospitalized severe acute respiratory syndrome-related coronavirus 2-positive Brazilian people who attended the Family Health Care Unit. The co-occurrence of both self-reported olfactory and taste disorders was more frequent than self-reported olfactory or taste disorders alone.

Starch-PVA based films with Clitoria ternatea flower extract: Characterization, phenolic compounds release and compostability.

The kinetic release of phenolic compounds from biodegradable films with Clitoria ternatea flower extract (ECT) in different food-simulant fluids and compostability were evaluated for the first time. This work aimed to incorporate ECT in starch-PVA-based film formulations, and the antioxidant capacity, total phenolic compounds, opacity, color, mechanical properties, compostability, and polyphenol release in different fluid simulants were determined. The results obtained showed that antioxidant activity and the total phenolic compounds were ECT dose dependent. Due to its antioxidant properties, ECT interfered with the film's composting process, reaching an average weight loss of 70 %. Additionally, the addition of ECT interfered with the mechanical properties, reducing the tensile strength, probably due to the plasticizer effect. The type of simulating fluid influenced the release of polyphenols from the films, and the presence of water favored the release because it hydrated and swelled the starch-PVA matrix, facilitating diffusion. The classic zero- and first-order models were the most effective in describing the release kinetics of polyphenols from the films. The results of this study demonstrate that the antioxidant potential and the release of polyphenols from starch-PVA-based films in different simulated fluids allow their application in active packaging, making them a sustainable alternative for food preservation.

Percepção de cuidadores sobre a qualidade de serviços de Fisioterapia Neuropediátrica em Centros de reabilitação no estado da Paraíba, Brasil / Caregiver perception of the quality of Neuropediatric Physiotherapy services at rehabilitation Centers in the State of Paraíba, Brazil

Este trabalho teve como objetivo avaliar a percepção de curadores sobre a qualidade dos serviços de Fisioterapia neuropediátrica ofertados em Centros Especializados em reabilitação (CER) no Brasil. Trata-se de um estudo transversal, quantitativo, de caráter avaliativo, cujo público-alvo foi representado por cuidadores das crianças em reabilitação. O instrumento AQSF-Neuroped foi utilizado para avaliar a qualidade dos serviços de Fisioterapia neuropediátrica em três CER, com base na percepção de 320 cuidadores. Utilizou-se o teste de hipótese para uma proporção a partir de cada item e dimensão do AQSF-Neuroped. Os modelos Weight of Evidence e Análise de Classes Latentes foram usados para avaliar o comportamento de variáveis sobre a percepção de qualidade. Obteve-se um escore médio total de qualidade de 133±14 pontos, implicando uma percepção positiva de qualidade; porém, há aspectos relacionados à estrutura física (dimensão interpessoal) e ao acesso (dimensão organizacional II) que precisam ser aprimorados (p-valores<0,05) para melhor atender às expectativas dos cuidadores. O CER B foi melhor avaliado dentre os demais serviços (IV<0,10). A ACL permitiu identificar, por meio da formação de grupo, características do cuidador que determinaram uma perspectiva positiva ou negativa da qualidade. Assim, disponibilizou-se os resultados para subsidiar as melhores práticas nos serviços.

This study evaluates the perception of caregivers of the quality of neuropediatric physiotherapy services offered at specialized rehabilitation centers (SRC) in Brazil. This is a cross-sectional, quantitative, evaluative study whose target population was caregivers of children in rehabilitation. The AQSF-Neuroped instrument was used to evaluate the quality of three SRC based on the perception of 320 caregivers. The one-proportion hypothesis test was used based on each AQSF-Neuroped item and dimension. The Weight of Evidence and Latent Class Analysis models were used to evaluate the influence of variables on the perception of quality. A mean overall quality score of 133±14 points indicated a positive perception of quality; however, there were aspects related to physical structure (Interpersonal Dimension) and access (Organizational Dimension II) that needed to be improved (p-values<0.05) to better meet the expectations of caregivers. By group formation, the LCA enabled identification of the caregivers' characteristics that determined either a positive or negative perspective of the quality. SRC B was best evaluated among all SRC (IV<0.10). Finally, managers are provided with results to support improvements in services.

Effects of the COVID-19 pandemic on delays in diagnosis-to-treatment initiation for breast cancer in Brazil: a nationwide study.

Background: Short period from diagnosis to breast cancer (BC) treatment initiation remains challenging for the public health system in Brazil, which may have been further affected by the coronavirus disease-2019 (COVID-19) pandemic. This study assessed BC diagnosis-to-treatment intervals (DTi) in Brazil and the possible effects of the COVID-19 outbreak on delays. Methods: The Painel de Monitoramento de Tratamento Oncológico database was queried to obtain the number of Brazilian patients with a BC confirmed diagnosis and initiating cancer treatment in the pre-COVID-19 (2013-2019) and during the COVID-19 (2020-2021) periods, adopting a 60-day limit as timely treatment. A p-value of <0.05 was considered significant. Results: A total of 315,951 cases were included (females: 99.3% and males: 0.7%), of which 251,667 and 64,284 records were computed before and during the COVID-19 years, respectively. Most patients failed to perform the first cancer treatment within 60 days (>60: 51.8%). We observed an upward trend in the number of BC treatments provided in the pre-COVID-19 years (r2 = 0.9575; p < 0.05), but the volume of treatments exhibited an average reduction of 24.6% yearly during the COVID-19 pandemic. The average DTi in days was 122.4, 122.5 and 122.3 in the total period studied, before and during the COVID-19 outbreak, respectively. The arrival of COVID-19 in Brazil increased the chances of treatment delay (OR = 1.043; p < 0.05) and inverted the proportion of early/advanced stages at BC diagnosis (55.8%/44.2%-48.4%/51.6%). Conclusion: COVID-19 has imposed changes in BC care in Brazil, reducing the number of treatments provided by the Brazilian public health system, increasing the chances of delayed treatment initiation despite no differences in DTi averages being identified, and raising the proportion of advanced-stage diagnoses.

Air velocity spatial variability in open Compost-Bedded Pack Barn system with positive pressure ventilation.

In Compost-Bedded Pack Barn (CBP) systems, air velocity is linked with the thermal comfort of housed dairy cattle and bedding quality and, therefore, assessing ventilation efficiency is essential. In this context, the objective of this study was to evaluate and characterize dependence and spatial distribution of air velocity at the 1.5 m height (vair,M) and at bedding level (vair,B) in an open CBP system with positive pressure ventilation. The study was conducted in 2021, in a facility located in the Zona da Mata region, Minas Gerais, Brazil. The facility area was divided into a mesh composed of 55 equidistant points, where vair,M and vair,B data were collected in the morning (09:00 a.m.) and afternoon (03:00 p.m.) periods, during three weeks in Brazilian winter. Geostatistics techniques were used to assess dependence and spatial distribution. In both periods evaluated, there were a strong occurrence of spatial dependence and non-uniform vair,M and vair,B distributions. The vair,M and vair,B values were lower than recommended (1.8 m∙s-1) in more than 65.0% of the area. Adequate ventilation levels were observed only in the first 20.0 m of the facility, from Southeast to Northwest, because of the fan lines present.

Trends in the morbidity and mortality of coronavirus disease 2019 in different ethnic groups and gender in a large Brazilian city.

As the coronavirus disease 2019 (COVID-19) outbreak spread, evidence has emerged that gender and race would bear a disproportionate impact on the morbimortality of COVID-19. Here, we conducted a retrospective observational study using the TabNet/Departamento de informática do sistema único de saúde platform of the city of São Paulo. COVID-19 records from March 2020 through December 2021 were included, and we evaluated the temporal trends of confirmed cases and case fatality rate by gender and ethnicity. Statistical analysis was performed using the R-software and BioEstat-software, considering p < 0.05 significant. From March/2020 to December/2021, 1 315 160 COVID-19 confirmed cases were recorded (57.1% females), and 2973 deaths were due to COVID-19. Males presented higher median mortality (0.44% vs. 0.23%; p < 0.05) and intensive care unit (ICU) admission rates (0.34% vs. 0.20%; p < 0.05). Men were also associated with a higher risk of death (risk ratio [RR] = 1.28; p < 0.05) and a higher chance of requiring ICU care (RR = 1.29; p < 0.05). Black ethnicity was associated with a higher risk of death (RR = 1.19; p < 0.05). White patients were more likely to require ICU admission (RR = 1.13; p < 0.05), whereas Browns were associated with a protective effect (RR = 0.86; p < 0.05). Furthermore, men presented a higher chance of death than women across the three major ethnic groups: Whites (RR = 1.33; p < 0.05), Blacks (RR = 1.24; p < 0.05), and Browns (RR = 1.35; p < 0.05). In this study of COVID-19 in São Paulo, men were associated with worse outcomes, including in the three major ethnicities in the population. Blacks exhibited a higher risk of death, Whites were more likely to require intensive care, and Browns were at protection from ICU hospitalization.

Effects of the Quality of Life on the Adaptation of People With An Intestinal Stoma.

The study aimed to examine the effects of the quality of life on the adaptation of people with an intestinal stoma. Cross-sectional study with 152 people with an ostomy. Three instruments were used: the sociodemographic and clinical characterization, Scale for the Level of Adaptation of Ostomy Patients, and City of Hope Quality of Life - Ostomy Questionnaire. The multiple linear regression model, multivariate technique, and cluster were used. The determination coefficient showed that 94.1% of the variability of the Adaptation scores is explained by the dimensions of quality of life. It can be seen that the highest standardized coefficients are the psychological dimension (ß = .386) and the social dimension (ß = .365), in which they produce the greatest changes in the average adaptation scores.

A taxa de mortalidade infantil é um indicador internacional que melhor representa os estágios de desenvolvimento econômico e social de um país ou região, uma vez que está diretamente ligada às características socioeconômicas e, consequentemente, sofre variações decorrentes de alterações neste padrão. Este artigo aponta os principais fatores que contribuíram no aumento da taxa de mortalidade infantil no Brasil no período de 2005 a 2019. Logo, configura-se como do tipo observacional, de caráter ecológico, com abordagem quantitativa, utilizando dados secundários sobre mortalidade infantil. A coleta dos dados foi realizada por intermédio do site do Departamento de Informática do Sistema Único de Saúde (DATASUS), utilizando a ferramenta denominada TABNET para subtrair as informações sobre Sistema de Informações sobre Mortalidade (SIM). Em seguida foram analisados no software estatístico RStudio e apresentados em tabelas e gráficos. Os principais motivos para óbitos foram: afecções originadas no período perinatal, malformações congênitas, deformidade e anomalias cromossômicas, doenças do aparelho respiratório e algumas doenças infecciosas e parasitárias, sendo assim, observou-se que o ambiente hospitalar com 90,93% atingiu os maiores casos de mortalidade, seguido do ambiente domiciliar com 5,53%. Em relação às regiões, o Sudeste obteve maior número de casos de mortalidade infantil, seguido da região Nordeste. Percebe-se que a redução da mortalidade infantil é de extrema importância, bem como a descrição dos fatores que contribuem para a sua redução.

The infant mortality rate is an international indicator that best represents the stages of economic and social development of a country or region, since it is directly linked to socioeconomic characteristics and, consequently, suffers variations arising from changes in this pattern. This article points out the main factors that contributed to the increase in the infant mortality rate in Brazil in the period from 2005 to 2019. Therefore, it is characterized as observational, ecological, with a quantitative approach, using secondary data on infant mortality. Data collection was carried out through the website of the Department of Informatics of the Unified Health System (DATASUS), using the tool called TABNET to subtract information on the Mortality Information System (SIM). They were then analyzed in the statistical software RStudio and presented in tables and graphs. The main reasons for death were: disorders originating in the perinatal period, congenital malformations, deformity and chromosomal abnormalities, respiratory system diseases and some infectious and parasitic diseases. Thus, it was observed that the hospital environment with 90.93% reached the highest mortality cases, followed by the home environment with 5.53%. In relation to the regions, the Southeast region had the highest number of infant mortality cases, followed by the Northeast region. It is perceived that the reduction of infant mortality is of extreme importance, as well as the description of the factors that contribute to its reduction.

Representações sociais de pessoas vivendo com hiv: do abandono do tratamento à motivação para a retomada / Representaciones sociales de las personas que viven con vih: del abandono del tratamiento a la motivación para reanudar / Social representations of people living with hiv: from treatment abandonment to motivation for resuming

Introdução: O uso contínuo da terapia antirretroviral é eficiente para interromper a replicação viral causada pelo Vírus da Imunodeficiência Humana impedindo o comprometimento do sistema imunológico e o aparecimento das infecções oportunistas. Estima-se que em 2021, 10,2 milhões de pessoas infectadas pelo HIV não se beneficiaram com o uso dos antirretrovirais em todo o mundo. No mesmo ano esse indicador atingiu 333 mil pessoas, e na esfera municipal de Londrina, 288 pessoas vivendo com HIV encontravam-se em abandono do tratamento. Objetivo: Apreender as representações sociais de pessoas vivendo com HIV acerca do abandono do tratamento e a motivação para a retomada. Percurso metodológico: Trata-se de um estudo qualitativo pautado na Teoria das Representações Sociais de Serge Moscovici. O cenário foi um Serviço de Atendimento Especializado em HIV/aids localizado na região Sul do Brasil. A população foi composta por 288 pessoas diagnosticadas com HIV em abandono do tratamento por período superior a 100 dias. Destas, 250 foram excluídas em função de critérios relacionados a informações cadastrais incompletas ou equivocadas, e aspectos impeditivos do comparecimento ao serviço e de contato. Outras 18 pessoas foram consideradas perdas por desistência. A amostra foi composta por 20 pessoas que se enquadraram aos critérios de elegibilidade e aceitaram participar do estudo. A coleta das informações ocorreu entre junho de 2021 e junho de 2022 em entrevistas semiestruturadas audiogravadas e transcritas na íntegra. Para análise das falas foi utilizado o discurso do sujeito coletivo. Resultados: Participaram do estudo 20 pessoas vivendo com HIV, sendo 12 homens e oito mulheres, com idade entre 27 e 55 anos. O tempo de abandono variou entre 210 e 1580 dias. A análise das entrevistas permitiu a emersão de 18 ideias centrais e duas ancoragens, as quais foram agrupadas em quatro grandes temas: 1) Abandono do tratamento por questões intrínsecas à pessoa vivendo com HIV; 2) Abandono do tratamento por questões ligadas à terapia medicamentosa; 3) Abandono do tratamento por dogmas sociais; 4) Forças propulsoras para a retomada do tratamento. Considerações finais: A análise qualitativa das representações sociais das pessoas vivendo com HIV indicou que o abandono da terapia antirretroviral é multifatorial, e envolve questões socioculturais, geográficas, familiares e biológicas. É essencial considerar todas as questões que permeiam e impactam as vidas das pessoas vivendo com HIV em abandono do tratamento para além das questões biológicas, viabilizando a implementação de ações que contribuam para a efetividade das políticas públicas de saúde no intuito de estimular a adesão e encorajar a retomada ao tratamento. Almeja-se que esta investigação possa despertar para as questões subjetivas ao universo da pessoa que vive com HIV e estas respeitadas na prática humanizada, voltadas ao incentivo do tratamento contínuo para controle da infecção e promoção da qualidade de vida.

Introduction: The continuous use of antiretroviral therapy is efficient to interrupt viral replication caused by the Human Immunodeficiency Virus, preventing the compromise of the immune system and the appearance of opportunistic infections. It is estimated that in 2021, 10.2 million people infected with HIV did not benefit from the use of antiretrovirals worldwide. In the same year, this indicator reached 333,000 people, and at the municipal level of Londrina, 288 people living with HIV were abandoning treatment. Objective: To apprehend the social representations of people living with HIV about abandoning treatment and the motivation for resuming it. Methodological path: This is a qualitative study based on Serge Moscovici's Theory of Social Representations. The setting was a Specialized Care Service for HIV/AIDS located in the south of Brazil. The population consisted of 288 people diagnosed with HIV who had abandoned treatment for more than 100 days. Of these, 250 were excluded due to criteria related to incomplete or wrong registration information, and aspects that impeded attendance at the service and contact. Another 18 people were considered dropout losses. The sample consisted of 20 people who met the eligibility criteria and agreed to participate in the study. Data collection took place between June 2021 and June 2022 in semi-structured interviews that were audio-recorded and transcribed in full. For the analysis of the speeches, the collective subject discourse was used. Results: 20 people living with HIV participated in the study, 12 men and eight women, aged between 27 and 55 years. The abandonment time varied between 210 and 1580 days. The analysis of the interviews allowed the emergence of 18 central ideas and two anchors, which were grouped into four major themes: 1) Abandonment of treatment due to issues intrinsic to the person living with HIV; 2) Abandonment of treatment due to issues related to drug therapy; 3) Abandonment of treatment by social dogmas; 4) Driving forces for the resumption of treatment. Final considerations: The qualitative analysis of the social representations of people living with HIV indicated that the abandonment of antiretroviral therapy is multifactorial, and involves sociocultural, geographic, family and biological issues. It is essential to consider all the issues that permeate and impact the lives of people living with HIV who abandon treatment in addition to biological issues, enabling the implementation of actions that contribute to the effectiveness of public health policies in order to stimulate adherence and encourage resumption of treatment. It is hoped that this investigation may awaken to the subjective issues of the universe of the person living with HIV and these respected in humanized practice, aimed at encouraging continuous treatment to control the infection and promote quality of life.

Consideraciones finales: El análisis cualitativo de las representaciones sociales de las personas viviendo con VIH indicó que el abandono de la terapia antirretroviral es multifactorial, e involucra cuestiones socioculturales, geográficas, familiares y biológicas. Es fundamental considerar todas las cuestiones que permean e impactan la vida de las personas que viven con el VIH que abandonan el tratamiento además de las cuestiones biológicas, posibilitando la implementación de acciones que contribuyan a la efectividad de las políticas públicas de salud para estimular la adherencia y alentar la reanudación. De tratamiento se espera que esta investigación pueda despertar a las cuestiones subjetivas del universo de la persona que vive con VIH y estas respetadas en la práctica humanizada, con el objetivo de incentivar el tratamiento continuo para el control de la infección y promover la calidad de vida.
