RESUMO

OBJECTIVES: To clarify the hearing outcomes after endoscopic type I tympanoplasty for medium and large perforations due to chronic otitis media. METHODS: We examined the clinical records of patients who underwent endoscopic type I tympanoplasty for medium and large perforations of the eardrum resulting from chronic otitis media between January 2019 and December 2021. We analyzed the changes in hearing pre- and post-operation in patients with healed eardrums and assessed the impact of tympanosclerosis on hearing. Patients with incomplete follow-up data, middle ear cholesteatoma, stapes fixation, severe lesions in the tympanic antrum and mastoid necessitating mastoidectomy and/or ossicular chain reconstruction were excluded. RESULTS: A total of 156 patients underwent analysis for audiological outcomes. Among them, 63 had medium tympanic membrane perforations, with 18 cases showing calcification of the tympanic membrane and 20 cases with calcification in the tympanic cavity. Additionally, 93 cases had large tympanic membrane perforations, with 25 cases showing tympanic membrane calcification and 32 cases with tympanic cavity calcification. Prior to surgery, the Air Conduction threshold (AC) in the large perforation group was higher than in the medium perforation group, particularly at low frequencies, measuring (47.4 ± 13.3 dB) and (41.2 ± 14.7 dB), respectively (p-value < 0.05). Following surgery, both groups experienced an improvement in AC, measuring (33.6 ± 13.9 dB) and (32.6 ± 12.8 dB), respectively, with no significant difference noted (p-value > 0.05). There was no significant change in Bone Conduction threshold (BC) before and after surgery in either the large or medium perforation groups (all p-values > 0.05). Except for 4000 Hz an increase, bone conduction did not increase post-surgery, instead showing further improved. Pre-surgery, the Air-Bone Gap (ABG) in the large and medium perforation groups was (27.7 ± 8.5 dB) and (21.8 ± 8.3 dB), respectively, mainly affecting low frequencies, with a statistically significant difference noted (p-value < 0.05). Following surgery, ABG in both groups improved to (16.3 ± 7.6 dB) and (15.7 ± 8.4 dB), respectively, with no significant difference observed (p-value > 0.05). There was no significant difference in hearing pre-surgery among the groups with No calcification (No), Tympanic Membrane Calcification (TM), and Tympanic Cavity Calcification (TC). However, TC significantly impacted low frequency (250-500 Hz) AC and ABG. The differences in AC and ABG pre-surgery between TC and No group, and TC and TM group (at 250-500 Hz) were statistically significant (all p-values < 0.05). Preoperative ABG in TM group was better than in No group and TC group, suggesting minimal impact of tympanic membrane calcification on hearing. No interaction was observed between tympanic membrane perforation size and tympanosclerosis on hearing. Post-surgery, both large and medium tympanic membrane perforation groups, regardless of tympanosclerosis presence, showed good AC and ABG, with no statistically significant difference in △ABG (all p-values > 0.05). CONCLUSION: Preoperative AC and ABG were increase in cases of large tympanic membrane perforations and medium tympanic membrane perforations with tympanic cavity calcification. Surgical intervention led to more significant hearing improvement in these patients. However, irrespective of tympanic membrane perforation size and the presence of tympanosclerosis, as long as the ossicular chain remains intact and functional, postoperative AC and ABG outcomes are satisfactory. Endoscopic type I tympanoplasty proves effective in achieving improved hearing outcomes for patients with medium to large tympanic membrane perforations and tympanosclerosis, provided there is no ossicle chain fixation. LEVEL OF EVIDENCE: Level 4.

RESUMO

Objective: We aimed to identify the factors associated with using digital platforms for physical activity during the COVID-19 pandemic among adults living in Southern Brazil. We also compared the trajectory of physical activity between users and non-users and by type of digital platform used. Methods: We analyzed data from the PAMPA (Prospective Study About Mental and Physical Health in Adults) cohort. The study started in June 2020, and tracked participants through three waves (December 2020, June 2021, and June 2022). The exposure variable was usingf digital platforms for physical activity. The outcome measure was minutes per week of physical activity. We employed a generalized linear model with robust variance to explore the interaction between time and the use of digital platforms, adjusting for sociodemographic covariates and the presence of chronic diseases. Results: The proportion of participants using digital platforms for physical activity declined from 36.8% in 2020 to 25.6% in 2021 and further to 13.5% in 2022. Using digital platforms for physical activity was associated with a higher mean daily physical activity during the COVID-19 pandemic. Participants who used digital platforms were more likely to be physically active when compared to their inactive contemparts throughout the entire study period. Notably, social media emerged with greater influence in the physical activity practice among digital platforms. Conclusion: Using these platforms had a positive impact on increasing the level of physical activity among the participants.

RESUMO

Abstract Social networks have become an ideal space for the exchange of information and knowledge. The objetive of this study was to determine the usefulness of the implementation of Instagram as a didactic tool to promote and facilitate student learning in the theoretical and laboratory courses of Pediatric Dentistry and Orthodontics during 2022. Private Instagram accounts were created for each of the four courses. During 4 months relevant information was posted to review concepts and strengthen the teaching-learning process of the students. At the end of the courses, a survey was conducted containing the following variables: usefulness of the social network, amount of information provided, preferred place to view content (wall or stories) and whether students recommend the use of Instagram in other courses of the Department of Dentistry and Orthodontics. For the association of variables, the chi-square test was used, value of p<0.05, 95%Cl. The participation in the accounts was 222 individuals; the interaction of the students with the accounts was 87.5% with respect to the stories, 95% observed the stories completely. There was a statistically significant difference with respect to where the information was posted: stories was the preferred place for students. There were 167 students participating in the survey. All the students found very useful or useful the content of the application on the social network.100% of the respondents recommended keeping the implementation of social networks in the theoretical courses of the Department. Instagram is not only a social application but also a channel to make the teaching process more dynamic and attractive. Teachers can integrate this social platform to foster motivation and learning in students.

RESUMO

Platelet lysate (PL) is investigated as a potential replacement for fetal bovine serum (FBS) in cell culture. However, there is limited research on its impact on the immune profile of equine mesenchymal stromal cells (eMSCs). This study aimed to evaluate the effects of different PL formulations on the proliferative capacity, multipotentiality, and immune profile of equine adipose tissue-derived MSCs (eAD-MSCs). In vitro growth kinetics and trilineage differentiation of eAD-MSCs (n = 7) were assessed under three culture conditions: medium-concentration PL (MPL), high-concentration PL (HPL), and FBS as a control. The immune profile was evaluated by studying the expression of immunogenic receptors such as MHC I, MHC II, and immunomodulatory molecules IL-6, IL-10, and TNF-α, determined by gene expression, surface marker expression, and cytokine quantification. Both PL formulations, pooled from 5 donors, exhibited 3.3 and 6.5-fold higher platelet counts than baseline plasma for MPL and HPL, respectively. Higher concentrations of TGF-ß and PDGF were found in both PL formulations compared to baseline. Furthermore, MPL and HPL subcultures demonstrated proliferative, clonogenic, and multipotent capacities similar to FBS. The immune profile of PL-cultured cells exhibited gene expression levels related to immunogenicity and immunomodulation similar to the reference condition, and the surface antigen presence of MHC II was also similar. However, HPL media exhibited higher IL-6, IL-10, and TNF-α concentrations in the culture supernatant. In conclusion, both PL media contained higher concentrations of growth factors compared to FBS, supporting the in vitro culture of eAD-MSCs with proliferative, clonogenic, and multipotent capacity similar to the reference medium. Nonetheless, PL usage led to a variation in the immunomodulatory cytokine microenvironment, with higher concentrations of IL-6, IL-10, and TNF-α in HPL media compared to MPL and FBS.

RESUMO

Background: Digital inclusion of older people is an important agenda for the future and well-being of the older population, as it represents a form of social inclusion with significant gains for healthy aging. The present study aimed to understand the experiences of Brazilian older adults who use smartphones and the implications in their daily lives. Method: A qualitative study was developed using a constructivist grounded approach. Older people (≥60 years) with prior access to a smartphone were invited to participate in the study. Participation took place through semi-structured, audio-recorded interviews. Data collection and analysis occurred simultaneously using a constant comparative approach. Data management and analysis used the Atlas.ti® software. Results: Overall, 37 older people participated, with an average age of 70.60 ± 6.95 years, predominantly female (n = 33), white (n = 25), married (n = 26) and retired (n = 27). The first sample group included 27 older people with family support and the second group included 10 older people without family support (who lived alone in their homes). A core category emerged from the data analysis-"Expanding the personal and social development of older adults through smartphone communication"-around which three main categories emerged: 1) The smartphone as "a window to the world"; 2) The problem of misinformation and fake news on virtual networks; 3) Technological paradoxes in the use of smartphones. Conclusions: The digital transition associated with smartphone use brings unimaginable benefits to older adults who adopt positive habits to improve their well-being and expand their social connections, following efforts proposed by the Decade of Healthy Aging. However, older adults still face disparities and experience a significant digital divide, which represents a major challenge. Barriers to access are further aggravated in developing countries. We hope this study contributes to public health policies on digital inclusion and healthy aging.

RESUMO

BACKGROUND: The frequency of health-related information seeking on the internet and social media platforms has increased remarkably. Thus, the ability to understand and select accurate health-related information online, known as EHealth literacy, is crucial for the population. Therefore, this study aimed to evaluate how eHealth literacy influences the critical analysis of oral health-related information obtained from the Internet and its influence on oral health-related behaviors.  METHODS: A cross-sectional online study was conducted with 418 Brazilian adults who responded to the eHEALS questionnaire, with questions regarding the influence of online information on oral health decisions. Socioeconomic and demographic characteristics were also collected. RESULTS: The mean eHEALS score was 27.85 (± 8.13), with a range spanning from 8 to 40 points. Participants with higher eHEALS scores reported using social media platforms to seek for dentists and to acque information about symptoms, diagnoses, and treatments. Furthermore, this group tended not to disregard professional health recommendations based on Internet information and abstained from utilizing products promoted by digital influencers. In multivariate models, increased eHEALS scores were associated with reduced consumption of products endorsed by digital influencers. CONCLUSIONS: The findings from this study suggest that individuals with higher scores on the eHealth literacy questionnaire often conduct research on their health status and seek for health care providers on the Internet. Moreover, these individuals were less likely to be influenced by digital influencers.

RESUMO

The use of yeast to biologically control the production of ochratoxin A, which is caused by filamentous fungal growth, in coffee farms is a promising alternative to conventional methods. However, yeast strains, environmental field conditions, and the chemical composition of grains / fruits can influence the effectiveness of biological control agents. We tested the efficiency of different yeast strains in controlling three species of ochratoxigenic fungi in a coffee-based medium. The reasons and mechanisms behind the varying sensitivities of different Aspergillus species to biological control remains unclear. Aspergillus carbonarius rapidly assimilated carbon sources, giving it an advantage over yeasts in substrate colonisation. Saccharomyces cerevisiae CCMA 0159 inhibited all three fungal species, achieving efficiencies of 74.4%, 100%, and 80.9% against A. carbonarius, A. westerdijkiae, and A. ochraceus, respectively. The strategies employed by S. cerevisiae CCMA 0159 to inhibit the growth of ochratoxigenic fungi included competition, production of fungicidal volatile compounds, and alteration of the substrate's physicochemical properties. Our results indicate that among the yeast isolates tested, S. cerevisiae CCMA 0159 is the most effective in inhibiting ochratoxigenic fungi in coffee, including the more resistant A. carbonarius.

RESUMO

This study examined the association between media and Instagram interaction patterns with weight bias among undergraduate nutrition students in the Brazilian Nutritionists' Health Study. We also explored the potential mediating role of students' own body image perception in these relationships. A total of 406 students (78% women) participated in this cross-sectional analysis. Sociodemographic data, media influence, Instagram interaction patterns, body image perception, and weight bias were assessed using semi-structured questionnaires. Findings indicated that exposure to fitness content on Instagram (ß = 0.17, p < 0.001) and the pursuit of an ideal athletic body (ß = 0.12, p = 0.034) were associated with increased weight bias. In contrast, engagement with body diversity content (ß = -0.23, p < 0.001) and perceived pressure from media to conform to appearance ideals (ß = -0.24, p < 0.001) had a mitigating effect on weight bias. Notably, body image perception did not mediate these relationships (p > 0.05). In conclusion, this study revealed a link between media exposure and weight bias among undergraduate nutrition students, independent of their body image perception. Developing social media literacy programs that encourage students to critically evaluate media content is imperative to reduce weight bias. Additionally, a deeper examination of the media content that contributes to weight bias and the potential need for targeted regulatory measures is warranted.

RESUMO

A positive relationship has been reported between advanced periodontitis and carotid intima-media thickness (cIMT) measurement. The aim of this study was to investigate this relationship with parameters for periodontitis, such as PISA and systemic inflammation biomarkers. An observational descriptive cross-sectional study was conducted. A blood sample was collected from 75 subjects to analyze glucose, total cholesterol, HDL, LDL, and cytokine values. Increased cIMT was found in 32% of the patients with fewer teeth. Patients with periodontitis had a larger periodontal inflamed surface area (PISA) (p = 0.000) and had a 1.42-times-higher risk of having increased cIMT values compared to periodontally healthy individuals, though without a statistically significant association. Higher values in the left cIMT, IL-8, and TNF-α were found in men than in women with significant differences. In the multivariate analysis involving cytokines, age continues to be linked to increased cIMT values. INF-γ showed a trend towards a protective effect; as the IMT-M decreases, there is an increase in the expression of INF-γ, and a higher proportion of subjects with elevated INF-γ concentrations demonstrated normal IMT-C. This study did not find a statistically significant association between cIMT and periodontal disease, but the risk of having increased cIMT is 1.42-times higher for individuals with periodontitis.

RESUMO

BACKGROUND: Acute otitis media (AOM) causes inflammation and hearing loss. Ventilation tubes are key in treatment. 3D printing improves prostheses in otorhinolaryngology, offering precision and greater adaptability. MATERIALS AND METHODS: An experimental study was conducted with Wistar rats from July to December 2020. 3D tympanostomy tube models were designed, with technical specifications and tests performed on inexpensive 3D printers. The tympanostomy tube was inserted endoscopically. RESULTS: Procedures were performed on five rats with implants in both ears. Pre-intervention pathologies, such as atical retraction and glue ear, were found. The PLA-printed tympanostomy tube showed improvement after adjustments. Histopathological results revealed significant middle and inner ear damage. CONCLUSION: In our study, the design and 3D printing of implants fulfilled the desired functions when modified, with a height of 5 mm. Complications included PLA degradation and ear damage. There were no adverse events during observation, highlighting the need for further research on 3D-printed implants.

RESUMO

CienciaPR, a nonprofit that brings together the largest network of Puerto Rican scientists and one of the largest networks of Hispanic/Latine scientists in the world, has collaborated with El Nuevo Día (END), Puerto Rico's newspaper of record, to increase culturally relevant stories in their science section. This Practice Insight quantifies and compares the presence of culturally relevant elements (e.g., referring to Puerto Rico, local landmarks, historic figures, slang) and other content information (e.g., topics, location, focus, protagonist) in articles authored by CienciaPR members versus articles by END, news agencies, and other organizations. Results demonstrate that CienciaPR-authored articles published in END featured culturally relevant elements more often (e.g., mentioned Puerto Rico, used Puerto Rican slang, stories located in Puerto Rico) than those by other sources.

RESUMO

Introduction The prevalence of otitis media (OM) is substantial all over the world. Epidemiological data related to the economic burden of OM globally is minimal. The present systematic review was undertaken to estimate the economic burden of this disease in various parts of the world. Objectives An extensive literature search was done using PRISMA guidelines to identify relevant studies that estimated the economic burden of OM in monetary terms. The databases searched were PubMed Central, Ovid, and Embase. The cost estimation was done for one specific year and then compared considering the inflation rate. Data Synthesis The literature search led to the inclusion of 10 studies. The studies evaluated direct and indirect costs in monetary terms. Direct costs (health system and patient perspective) ranged from USD (United States Dollar) 122.64 (Netherlands) to USD 633.6 (USA) per episode of OM. Looking at only the patient perspective, the costs ranged from USD 19.32 (Oman) to USD 80.5 (Saudi Arabia). The total costs (direct and indirect) ranged from USD 232.7 to USD 977 (UK) per episode of OM. The economic burden per year was highest in the USA (USD 5 billion). The incidence of OM episodes was found more in children < 5 years old. Introduction of pneumococcal conjugate vaccines decreased the incidence in children and now the prevalence in adults is of concern. Conclusion The economic burden of OM is relatively high globally and addressing this public health burden is important. Approaches for the prevention, diagnosis, and treatment should be undertaken by the health system to alleviate this disease burden.

RESUMO

Introduction Aural polyps are a misnomer. Any lesion can present as a mass in the external auditory canal. Aural polyps are proliferation of the granulation tissue due to long standing inflammatory process with associated otalgia and otorrhea. Objectives To document the clinicoradiological presentations, intraoperative findings, and histopathological diagnosis of aural polyp, correlating them. Methods In our study 81 patients underwent treatment for aural polyps in the department of Ear, Nose, and Throat (ENT) from April 1997 to April 2022. Results were tabulated, a simple descriptive analysis was done using the Statistical Package Social Sciences software, and the results obtained were represented as percentages and presented in tables. Results The majority (38) of the patients presenting with aural polyps were diagnosed with mucosal and squamous type of CSOM, and 22 with simple granulation polyps. There were also 5 patients with malignant otitis externa, 3 patients had glomus tumors, 2 patients with retained foreign bodies, and 3 patients with brain herniation. We also identified aberrant internal carotid artery, high jugular bulb, one patient had facial nerve neuroma, one patient had polyp from the tragus diagnosed with tuberculosis, one patient with keratosis obturans, and one with exostosis. Conclusion A thorough detailed examination and mastoid exploration with radiological and histopathological evaluation is mandatory for better defining the definitive treatment. Utmost care and meticulousness are advised for the surgeons while dealing with aural polyps to avoid any complications.

RESUMO

Introduction Myringoplasty is a common otologic procedure to restore the integrity of the tympanic membrane in cases of traumatic or pathologic perforations. Many grafting materials have been used with different techniques. Objective In the present work, we evaluate the surgical and audiological outcomes of periosteal graft overlying the mastoid cortex through a retroauricular incision in a pediatric cohort. Methods A retrospective study was carried out involving all children aged ≤ 16 years who underwent periosteal graft myringoplasty for the treatment of chronic suppurative otitis media with dry central perforation in our hospital from April 2019 to April 2021. All patients were followed up for one year to assess the anatomical success and functional outcomes by comparing the preoperative and postoperative (after six months) results of pure tone audiometry (PTA). Results The sample was composed of 36 patients; 20 of them were female (55.6%) and 16 were male (44.4%) subjects, with ages ranging from 7 to 16 (mean: 12.7) years. Four patients underwent surgery in both ears (with an interval of 6 to 9 months). Out of 40 surgeries performed, 38 ears have shown anatomical success (95%). A highly significant improvement in hearing was obtained (the mean difference between the pre- and postoperative results of the PTA was of 14.6 ± 3.45 dB ( p < 0.001). Conclusion We advocate the use of periosteal graft in the pediatric population as a good alternative for other types of grafts, with comparable and even better functional and anatomical outcomes.

RESUMO

BACKGROUND: The increased screen media use among children aged 3 to 5, particularly in the post-COVID era, is concerning. Despite several organizations' recommendation of a one-hour screen limit for young children, actual usage often exceeds this guideline. OBJECTIVE: This study explored the influence of parental characteristics such as self-efficacy, motivation, socioeconomic status, and cognitive abilities on children's screen time habits. METHODS: Employing a feature selection model, 251 caregivers answered an online survey, presenting data from themselves and on-screen usage for 126 girls and 125 boys. We found that the caregiver's executive functions, including cognitive flexibility, initiation, task monitoring, and material organization, significantly impact children's screen time. RESULTS: Our analysis highlighted the vital role of caregivers' self-efficacy in moderating children's screen usage. Family net income, children's age and gender, and motivations related to children's desires and behavioral control were also significant contributors to usage patterns. CONCLUSION: This study offers insights into interventions and effective parenting strategies in the digital age, highlighting the importance of addressing socio-demographic factors in understanding this complex issue.

RESUMO

The Chikungunya virus (CHIKV) presents global health challenges, with Brazil experiencing outbreaks since its introduction in 2014. In 2023, following a CHIKV outbreak in Minas Gerais (MG), social media was used to optimize an entomological survey aimed at identifying vectors and viral lineages and assessing insecticide resistance. Following Instagram posts, residents with suspected CHIKV infection were able to schedule mosquito aspirations. In total, 421 mosquitoes (165 Aedes aegypti and 256 Culex quinquefasciatus) were captured from 40 households in Salinas city (MG) and tested for the Dengue, Zika, and Chikungunya viruses through RT-qPCR. Twelve of 57 pools (10 Ae. aegypti and two Cx. quinquefasciatus) tested positive for CHIKV RNA. Viral RNA was also detected in the heads of nine Ae. aegypti, indicating viral dissemination but not in Cx. quinquefasciatus. Genome sequencing yielded the first near-complete genome from the 2023 outbreak, unveiling that the CHIKV strain belonged to the East/Central/South African (ECSA) genotype. Additionally, genetic analyses revealed high frequencies of kdr alleles, including in CHIKV-infected mosquitoes, suggesting resistance to pyrethroid insecticides in this Ae. aegypti population. Social media was important for guiding mosquito-capture efforts in CHIKV transmission hotspots, thus optimizing the opportunity for viral detection. These findings emphasize the urgent need for innovative vector studies and control strategies, as well as interdisciplinary approaches in public health interventions.

ABSTRACT Background: The community of Quilmes (Tucumán) encompasses 2400 mid- and high mountain inhabitants (1800 to 4000 meters above sea level). In 2018, a study was carried out on their cardiovascular health status (2018 SONQO-CALCHAQUÍ Program). Objective: The aim of this study is to update and expand the survey carried out in 2018, to obtain a broader panorama of the cardiovascular health of this community. Methods: A descriptive cross-sectional study was carried out in the Quilmes community, in people who voluntarily attended specially established clinics in September 2022. Questionnaires, laboratory tests, ECG, echocardiogram, anthropometric measurements, muscular resistance and strength tests were carried out. Results: A total of 186 patients (119 women and 67 men) aged 45.0±1.3 years attended the study. The prevalence of cardiovascular risk factors (hypertension 17.8%, smoking 14.1%, diabetes 4.9% and dyslipidemia 30.6%) was acceptable, but a high proportion of cases had not been examined in the last year. The diet consisted mainly of flour products, with little fresh fruit and vegetables. The prevalence of overweight (34.3%) and obesity (35.4%) was high. Forty percent of respondents had secondary or higher education. Good quality of life (69.5±1.1% of the maximum possible value of satisfaction on the self-perception scale) was reported. The Minimental Test average was 15.7±0.2 points. Prehensile strength in 55.8% of cases was below the normal range. Conclusions: The Quilmes population presents an acceptable physical condition, but with a high rate of overweight and obesity, due to the diet, a condition that should be considered in future health programs.

RESUMO

Introdução: Com o passar dos anos e o proporcional crescimento das mídia sociais, focado principalmente no culto ao corpo e à perfeição, a procura por cirurgias plásticas vem aumentando de forma avassaladora, despertando um interminável desejo pela mudança corporal, na maioria das vezes com promessas "irreais" de alguns profissionais. Método: Pesquisa composta por 62 pacientes dos sexos feminino e masculino, com idade entre 22 e 61 anos, residentes no estado de São Paulo, que já se submeteram a um procedimento de cirurgia plástica e/ou ainda passarão por procedimentos de cirurgia plástica e cosmiatria, que responderam ao questionário "A influência das mídias sociais na cirurgia plástica". Resultados: Os resultados demonstram que a mídia exerce um importante papel na escolha do cirurgião plástico, principalmente quando o sucesso dos procedimentos de cirurgia plástica e cosmiatria é demonstrado através de fotos de antes e depois. Conclusão: A cirurgia plástica é uma especialidade médica que desempenha um papel fundamental na transformação estética e psicológica de muitos indivíduos, no entanto, é importante ressaltar a necessidade de uma abordagem ética, com o objetivo de garantir o bem-estar dos pacientes e a excelência na prática médica.

Introduction: Over the years and with the proportional growth of social media, focused mainly on the cult of the body and perfection, the demand for plastic surgeries has increased overwhelmingly, awakening an endless desire for body change, most of the time with "unrealistic" promises" from some professionals. Method: Research consisting of 62 female and male patients, aged between 22 and 61 years, residing in the state of São Paulo, who have already undergone a plastic surgery procedure and/or will undergo plastic surgery and cosmiatry procedures, who responded to the questionnaire "The influence of social media on plastic surgery". Results: The results demonstrate that the media plays an important role in choosing a plastic surgeon, especially when the success of plastic surgery and cosmetic surgery procedures is demonstrated through before and after photos. Conclusion: Plastic surgery is a medical specialty that plays a fundamental role in the aesthetic and psychological transformation of many individuals, however, it is important to highlight the need for an ethical approach, to guarantee patients' well-being and excellence in medical practice.

RESUMO

ABSTRACT Introduction: Contrast-associated acute kidney injury (CA-AKI) is a deterioration of kidney function that occurs after the administration of a iodinated contrast medium (ICM). Most studies that defined this phenomenon used older ICMs that were more prone of causing CA-AKI. In the past decade, several articles questioned the true incidence of CA-AKI. However, there is still a paucity of a data about the safety of newer ICM. Objective: To assess the incidence of CA-AKI in hospitalized patients that were exposed to computed tomography (CT) with and without ICM. Methods: Prospective cohort study with 1003 patients who underwent CT in a tertiary hospital from December 2020 through March 2021. All inpatients aged > 18 years who had a CT scan during this period were screened for the study. CA-AKI was defined as a relative increase of serum creatinine of ≥ 50% from baseline or an absolute increase of ≥ 0.3 mg/dL within 18 to 48 hours after the CT. Chi-squared test, Kruskal-Wallis test, and linear regression model with restricted cubic splines were used for statistical analyses. Results: The incidence of CA-AKI was 10.1% in the ICM-exposed group and 12.4% in the control group when using the absolute increase criterion. The creatinine variation from baseline was not significantly different between groups. After adjusting for baseline factors, contrast use did not correlate with worse renal function. Conclusion: The rate of CA-AKI is very low, if present at all, with newer ICMs, and excessive caution regarding contrast use is probably unwarranted.

RESUMO Introdução: Lesão renal aguda associada ao contraste (LRA-AC) é uma deterioração da função renal que ocorre após a administração de meio de contraste iodado (MCI). A maioria dos estudos que definiram esse fenômeno utilizaram MCI mais antigos, mais propensos a causar LRA-AC. Na última década, diversos artigos questionaram a verdadeira incidência de LRA-AC. Entretanto, ainda há escassez de dados sobre a segurança dos MCI mais novos. Objetivo: Avaliar a incidência de LRA-AC em pacientes hospitalizados expostos à tomografia computadorizada (TC) com e sem MCI. Métodos: Estudo de coorte prospectivo com 1.003 pacientes submetidos a TC em hospital terciário, de dezembro/2020 a março/2021. Todos os pacientes internados com idade ≥ 18 anos que realizaram TC nesse período foram selecionados. A LRA-AC foi definida como aumento relativo de creatinina sérica de ≥ 50% em relação ao valor basal ou aumento absoluto de ≥ 0,3 mg/dL dentro de 18 a 48 horas após a TC. Utilizamos o teste qui-quadrado, teste de Kruskal-Wallis e modelo de regressão linear com splines cúbicos restritos para análises estatísticas. Resultados: A incidência de LRA-AC foi 10,1% no grupo exposto ao MCI e 12,4% no grupo controle ao usar o critério de aumento absoluto. A variação da creatinina em relação ao valor basal não foi significativamente diferente entre os grupos. Após ajuste para fatores basais, o uso de contraste não se correlacionou com pior função renal. Conclusão: A taxa de LRA-AC é muito baixa, caso exista, com MCIs mais novos, e a cautela excessiva quanto ao uso de contraste provavelmente não se justifica.
